The limits for life under multiple extremes.
Harrison, Jesse P; Gheeraert, Nicolas; Tsigelnitskiy, Dmitry; Cockell, Charles S
2013-04-01
Life on Earth is limited by physical and chemical extremes that define the 'habitable space' within which it operates. Aside from its requirement for liquid water, no definite limits have been established for life under any extreme. Here, we employ growth data published for 67 prokaryotic strains to explore the limitations for microbial life under combined extremes of temperature, pH, salt (NaCl) concentrations, and pressure. Our review reveals a fundamental lack of information on the tolerance of microorganisms to multiple extremes that impedes several areas of science, ranging from environmental and industrial microbiology to the search for extraterrestrial life.

Background: Researchers report difficulties in conducting research with children and young people with life-limiting conditions or life-threatening illnesses and their families. Recruitment is challenged by barriers including ethical, logistical and clinical considerations. Aim: To explore how children and young people (aged 0–25 years) with life-limiting conditions or life-threatening illnesses and their families were identified, invited and consented to research published in the last 5 years. Design: Systematic review. Data sources: MEDLINE, PsycINFO, Web of Science, Sciences Citation Index and SCOPUS were searched for original English language research published between 2009 and 2014, recruiting children and young people with life-limiting conditions or life-threatening illness and their families. Results: A total of 215 studies – 152 qualitative, 54 quantitative and 9 mixed methods – were included. Limited recruitment information but a range of strategies and difficulties were provided. The proportion of eligible participants from those screened could not be calculated in 80% of studies. Recruitment rates could not be calculated in 77%. A total of 31% of studies recruited less than 50% of eligible participants. Reasons given for non-invitation included missing clinical or contact data, or clinician judgements of participant unsuitability. Reasons for non-participation included lack of interest and participants’ perceptions of potential burdens. Conclusion: All stages of recruitment were under reported. Transparency in reporting of participant identification, invitation and consent is needed to enable researchers to understand research implications, bias risk and to whom results apply. Research is needed to explore why consenting participants decide to take part or not and their experiences of research recruitment. PMID:27609607

PA11 The dreamers - life, death and dreams.
Wischer, Pippa
2015-04-01
Palliative Care Victoria is building community capacity to have end of life conversations. To create a conversation resource. In partnership with Pippa Wischer, we published The Dreamers, an exploration of life, death and dreams through interviews and photographs of forty palliative care patients. The Dreamers was an effective advocacy tool during the 2014 Victorian State Election. Palliative care services are using it with patients and families. The photographs are being exhibited at a rural regional gallery with several other galleries expressing interest. Other applications are being explored (e.g. conversation cards). The Dreamers highlights the importance of personal stories in overcoming the taboos around death and the value of the arts to foster community engagement and social change. © 2015, Published by the BMJ Publishing Group Limited.

Intestinal failure in children and young people with neurodisabling conditions.
Wahid, Amar M; Powell, Colin V; Davies, Ieuan H; Evans, Jennifer A; Jenkins, Huw R
2017-05-01
Gastrointestinal dysmotility is common in children and young people with neurodisabling conditions. In this article we seek to highlight the increasing difficulties faced by paediatricians in managing intestinal failure in this patient group. It is becoming clear that, as the median age for survival increases, intestinal failure is a significant problem, and can in some cases become life-limiting. The ethical issues around starting children with life-limiting conditions on parenteral nutrition (PN) are extremely complicated, not least because we are ignorant of the mechanism of intestinal failure in these children, and indeed, which of these children might be able to return to enteral feeding after a period of PN. Our article highlights these issues, drawing on our experience of a particularly difficult case, which we hope will stimulate further discussion among paediatricians providing care for children with neurodisabling conditions.

Life expectancy--a commentary on this life table variable.
Singer, Richard B
2005-01-01
In 1992, I wrote an article on a method of modifying the Decennial US Life Table to accommodate any pattern of excess mortality expressed in terms of excess death rate (EDR), for the specific purpose of calculating the reduced life expectancy, e. I believe this was the first article published in the Journal of Insurance Medicine (JIM) that dealt specifically with life expectancy as an index of survival and risk appraisal, never used in the classification of extra mortality risk in applicants for life insurance. In this commentary, I discuss the 1989-91 US Decennial Life Table in detail. I link the subject matter of the 1992 article with several more recent articles that also focus on the utility of life expectancy in underwriting structured settlement annuities and preparing reports on life expectancy for an attorney in a tort case. A few references are given for further reading on life table methodology and its use in the most accurate estimate of life expectancy, given the inherent limitations of the life table and the limited duration of follow-up studies.

Paediatric palliative care is no longer restricted to patients with cancer and has been extended to patients with other chronic conditions, such as cystic fibrosis or neuromuscular disorders. This review focused on the current state of palliative care for children and adolescents with chronic kidney disease (CKD). We assessed the literature on CKD published up to August 2017. All the papers, except one from 1996, were published this century. This review discusses the role that palliative care plays in the process of decision-making and explores the possibilities of implementing palliative care into the routine therapy of affected patients and providing support for their families. Offering early palliative care as an integral part of the kidney, supportive care provided by the nephrology care team is both necessary and feasible for patients with CKD. As a minimum, a specialised palliative care team should be involved in patients with multiple comorbidities, in conservative treatment scenarios and in acute life-threatening complications. Further studies and guidelines are required to improve the care of patients with CKD and their families. Supportive palliative care should be implemented into the routine care of patients with life-limiting kidney disease. ©2017 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.
Thalassaemia in children: from quality of care to quality of life.
Amid, Ali; Saliba, Antoine N; Taher, Ali T; Klaassen, Robert J
2015-11-01
Over the past few decades, there has been a remarkable improvement in the survival of patients with thalassaemia in developed countries. Availability of safe blood transfusions, effective and accessible iron chelating medications, the introduction of new and non-invasive methods of tissue iron assessment and other advances in multidisciplinary care of thalassaemia patients have all contributed to better outcomes. This, however, may not be true for patients who are born in countries where the resources are limited. Unfortunately, transfusion-transmitted infections are still major concerns in these countries where paradoxically thalassaemia is most common. Moreover, oral iron chelators and MRI for monitoring of iron status may not be widely accessible or affordable, which may result in poor compliance and suboptimal iron chelation. All of these limitations will lead to reduced survival and increased thalassaemia-related complications and subsequently will affect the patient's quality of life. In countries with limited resources, together with improvement of clinical care, strategies to control the disease burden, such as public education, screening programmes and appropriate counselling, should be put in place. Much can be done to improve the situation by developing partnerships between developed countries and those with limited resources. Future research should also particularly focus on patient's quality of life as an important outcome of care. Published by the BMJ Publishing Group Limited.

Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is associated with high morbidity. The Quality of Life (QoL) assessment in this patient group with a limited life expectancy and high recurrence rate is important. Published data show an impairment of postoperative Quality of Life at 3 months postoperatively with an improvement over 6-12 months at levels higher than the baseline. Standardized instruments QoL have to be included in clinical trials assessing the efficacy of CRS and HIPEC. (c) 2009 Wiley-Liss, Inc.
Life style and peptic ulcer disease.
Yegen, Berrak C
2018-05-09
The risk of developing peptic ulcer disease (PUD) was shown to be associated with genetic inheritance, life-style and social status of the patients. Unhealthy lifestyle habits and failure in coping with stress have been closely associated with the occurrence of PUD. In contrary, limiting the use of analgesic drugs and glucocorticoids, controlling environmental and socioeconomic factors that predispose to H. Pylori infection, having a balanced diet, exercising regularly, coping successfully with stress, avoiding smoking, limiting alcohol intake and getting sufficient night sleep are essential in prevention and healing of PUD.

Psychometric properties of the Portuguese version of the Quality of Life Questionnaire (QOL-Q).
Albuquerque, Cristina P
2012-09-01
This study analyzes the psychometric properties of the Portuguese version of the Quality of Life Questionnaire (QOL-Q; Quality of Life Questionnaire Manual - 1993 Manual and 2004 Revision. 2004, IDS Publishing Company, Worthington, OH; Schalock & Keith 2004). The analysis of the factorial structure was carried out on a sample of 304 adults with intellectual disabilities, through the use of confirmatory (CFA) and exploratory (EFA) factor analysis. The relationships of the QOL-Q with life satisfaction and self-concept measures were determined in groups composed of respectively 72 and 78 adults with intellectual disabilities. Confirmatory factorial analysis indicated a poor adjustment of the original factor structure to the Portuguese data. EFA indicated the existence of four factors, which include 30 items, and that were also supported by CFA. The total score of the QOL-Q revealed a reduced correlation with life satisfaction, and a moderate correlation with the self-concept. The Portuguese version of the QOL-Q shows satisfactory psychometric properties, but also some limitations. © 2012 Blackwell Publishing Ltd.

To collect the views of experts to inform the development of an education package for multidisciplinary adult specialist palliative care (SPC) teams caring for young people with life-limiting conditions. A modified online Delphi process collated expert opinion on format, delivery and content of an education package to up-skill adult SPC teams. Round 1 participants (n=44) answered free-text questions, generating items for Round 2. In Round 2, 68 participants rated the extent to which they agreed/disagreed with the items on 5-point Likert-type scales. Median and mean scores assessed the importance of each item. IQR scores assessed level of consensus for each item; items lacking consensus were rerated by 35 participants in Round 3. In the Delphi, consensus was reached on a range of suggested formats, on who should deliver the training, and on several clinical, psychosocial and practical topics. Development of a continuous/rolling programme of education, tailored for content and mode of delivery and incorporated into working practice is recommended. As a direct outcome of the results of this study, a series of six linked study days has been established, focusing specifically on the issues around caring for young adults with life-limiting conditions and palliative care needs.

Although prolonging life is usually in the best interests of patients, the British Medical Association states that it is not appropriate to prolong life with no regard to its quality. Medical advances both on the battlefield and within the field hospitals have resulted in the unexpected survival of a number of British personnel, and in some cases, soldiers are being repatriated with injuries categorised as 'catastrophic'. This paper considers medical ethics based on the Beauchamp and Childress Four Principles framework with regard to whether catastrophically injured individuals should be repatriated without any prior advanced directive and without evaluation of future quality of life.

An up-to-date review of the behavioral assessments of language development in the first year of life is reported. After recalling the anatomical bases of the early development of the auditory system, the different stages of language development during the first year of life are considered: discrimination, transition and perception. The different kinds of behavioral assessment during the course of the first year are then described by stressing their indications and limitations.

Fetuses at low gestational age limit of viability, neonates with life threatening or life limiting congenital anomalies and deteriorating acutely ill newborn babies in intensive care, pose taxing ethical questions on whether to forego or stop treatment and allow them to die naturally. Although there is essentially no ethical difference between end of life decision between neonates and other children and adults, in the former, the fact that we are dealing with a new life, may pose greater problems to staff and parents. Good communication skills and involvement of all the team and the parents should start from the beginning to see which treatment can be foregone or stopped in the best interests of the child. This article deals with the importance of clinical ethics to avoid legal and moral showdowns and discusses accepted moral practice in this difficult area. Copyright © 2018. Published by Elsevier B.V.
The minimal cost of life in space.

The cost of keeping people alive in space is assessed from a theoretical viewpoint and using two actual designs for plant growth systems. While life support is theoretically not very demanding, our ability to implement life support is well below theoretical limits. A theoretical limit has been calculated from requirements and the state of the art for plant growth has been calculated using data from the BIO-Plex PDR and from the Cornell CEA prototype system. The very low efficiency of our current approaches results in a high mission impact, though we can still see how to get a significant reduction in cost of food when compared to supplying it from Earth. Seeing the distribution of costs should allow us to improve our current designs. c2004 COSPAR. Published by Elsevier Ltd. All rights reserved.

This bibliography is comprised of approximately 1200 reference citations related to the mechanics of failure in aerospace structures. Most of the references are for information on life prediction for materials exposed to monotonic and cyclic loading in elevated temperature environments such as that in the hot end of a gas turbine engine. Additional citations listed are for documents on the thermal and mechanical effects on solar cells in the cryogenic vacuum environment; radiation effects on high temperature mechanical properties; and high cycle fatigue technology as applicable to gas turbine engine bearings. The bibliography represents a search of the literature published in the period April 1962 through April 1974 and is largely limited to documents published in the United States. It is a companion volume to NASA CR-134750, Life Prediction of Materials Exposed to Monotonic and cyclic Loading - A Technology Survey.

Purpose: The purpose was to develop an end-of-life care (EOLC) policy for patients who are dying with an advanced life limiting illness and to develop practical procedural guidelines for limiting inappropriate therapeutic medical interventions and improve the quality of care of the dying within an ethical framework and through a professional and family/patient consensus process. Evidence: The Indian Society of Critical Care Medicine (ISCCM) published its first guidelines on EOLC in 2005 [1] which was later revised in 2012.[2] Since these publications, there has been an exponential increase in empirical information and discussion on the subject. The literature reviewed observational studies, surveys, randomized controlled studies, as well as guidelines and recommendations, for education and quality improvement published across the world. The search terms were: EOLC; do not resuscitate directives; withdrawal and withholding; intensive care; terminal care; medical futility; ethical issues; palliative care; EOLC in India; cultural variations. Indian Association of Palliative Care (IAPC) also recently published its consensus position statement on EOLC policy for the dying.[3] Method: An expert committee of members of the ISCCM and IAPC was formed to make a joint EOLC policy for the dying patients. Proposals from the chair were discussed, debated, and recommendations were formulated through a consensus process. The members extensively reviewed national and international established ethical principles and current procedural practices. This joint EOLC policy has incorporated the sociocultural, ethical, and legal perspectives, while taking into account the needs and situation unique to India. PMID:25249748

Research with adults on the autism spectrum is as yet limited in scope and quality. The present study describes quality of life (QoL) of a large sample of autistic adults in the UK and investigates characteristics that may be predictive of QoL. A total of 370 autistic adults from the Adult Autism Spectrum Cohort-UK (ASC-UK) completed the WHOQoL-BREF, and the Social Responsiveness Scale (SRS, autism symptom severity), along with the ASC-UK registration questionnaire giving information on mental health and their life situation. QoL for autistic adults was lower than for the general population for each WHOQoL domain. Younger participants reported higher QoL than older participants in psychological and environment domains. Males reported higher physical QoL than females, and females reported higher social QoL than males. Significant positive predictors of QoL were: being employed (physical QoL), receiving support (social and environment QoL), and being in a relationship (social QoL). Having a mental health condition and higher SRS total score were negative predictors of QoL across all four domains. Autistic adults require access to effective mental health interventions, and informal and formal support for their social difficulties, to improve their quality of life. Autism Res 2018. © 2018 The Authors Autism Research published by International Society for Autism Research and Wiley Periodicals, Inc. There has been limited research into the lived experience of autistic adults. Using the World Health Organization quality of life measure, we found that autistic people (370) in the UK reported their quality of life to be lower than that of the general population. Better quality of life was associated with being in a relationship; those with a mental health condition had poorer quality of life. This research suggests some ways in which autistic people can be helped to improve their quality of life. © 2018 The Authors Autism Research published by International Society for Autism Research and Wiley Periodicals, Inc.

The delivery of end-of-life care in nursing homes is challenging. This situation is of concern as 20% of the population die in this setting. Commonly reported reasons include limited access to medical care, inadequate clinical leadership and poor communication between nursing home and medical staff. Education for nursing home staff is suggested as the most important way of overcoming these obstacles. To identify educational interventions to enhance end-of-life care for nursing home staff and to identify types of study designs and outcomes to indicate success and benchmark interventions against recent international guidelines for education for palliative and end-of-life care. Thirteen databases and reference lists of key journals were searched from the inception of each up to September 2014. Included studies were appraised for quality and data were synthesised thematically. Twenty-one studies were reviewed. Methodological quality was poor. Education was not of a standard that could be expected to alter clinical behaviour and was evaluated mainly from the perspectives of staff: self-reported increase in knowledge, skills and confidence delivering care rather than direct evidence of impact on clinical practice and patient outcomes. Follow-up was often short term, and despite sound economic arguments for delivering effective end-of-life care to reduce burden on the health service, no economic analyses were reported. There is a clear and urgent need to design educational interventions that have the potential to improve end-of-life care in nursing homes. Robust evaluation of these interventions should include impact on residents, families and staff and include economic analysis. Published by the BMJ Publishing Group Limited.

The effect of periodontal surgery on patients' quality of life was investigated. Sixty patients received regenerative surgery or resective osseous surgery. Oral health-related quality of life and health-related quality of life instruments were used to assess the participants' quality of life before surgery and 4 weeks after surgery. Periodontal surgery can improve patients' quality of life by alleviating the physical pain and psychological discomfort. The scores were lower (more favorable) in the regenerative surgery group, and the functional limitations of the regenerative surgery group improved substantially compared with those of the resective osseous surgery group (P = 0.0421). The patients' oral health-related quality of life scores improved significantly after periodontal surgery. Clinicians can take advantage of the positive functional oral health-related quality of life impacts of regenerative surgery. Copyright © 2017. Published by Elsevier Taiwan.

The aim of this article is to show how, and in which context, astrobiological reasoning was employed before the establishment of astrobiology as a scientific discipline. By way of an example, I will discuss a popular science book published in 1931 by the Hungarian journalist Desiderius Papp. The author claims that this book represents an innovation in astrobiological reasoning, as it draws on contemporary biological research to conduct thought experiments, thereby coming up with concrete forms of possible extraterrestrial life. One of the most interesting of these forms was crystalline life. After a short overview on the history of this concept, this article will show how Papp drew on recent research by Otto Lehmann on liquid crystals to convey the idea that life may be based on other elements than carbon. The author concludes by arguing that popular science did not only make specialist knowledge accessible to a general public but also served to probe the limits of knowledge and point toward the situatedness of established categories and definitions.
[Limit of therapeutic effort in Spanish medical journals].

2012-01-01
In this paper we review articles concerning the limits of therapeutic effort that have been published in the past decade in journals directed at health professionals. Most of these articles are opinion pieces in which the influence of principlism is clear, even going so far as to justify the right to terminate life based on patient autonomy. It is time for personalistic bioethics to transmit its approaches in medical journals that are not specialized in bioethics.

Single motherhood is associated with poorer health, but whether this association varies between countries is not known. We examine associations between single motherhood and poor later-life health in the USA, England and 13 European countries. Data came from 25 125 women aged 50+ who participated in the US Health and Retirement Study, the English Longitudinal Study of Ageing and Survey of Health, Ageing and Retirement in Europe. We tested whether single motherhood at ages 16-49 was associated with increased risk of limitations with activities of daily living (ADL), instrumental ADL and fair/poor self-rated health in later life. 33% of American mothers had experienced single motherhood before age 50, versus 22% in England, 38% in Scandinavia, 22% in Western Europe and 10% in Southern Europe. Single mothers had higher risk of poorer health and disability in later life than married mothers, but associations varied between countries. For example, risk ratios for ADL limitations were 1.51 (95% CI 1.29 to 1.98) in England, 1.50 (1.10 to 2.05) in Scandinavia and 1.27 (1.17 to 1.40) in the USA, versus 1.09 (0.80 to 1.47) in Western Europe, 1.13 (0.80 to 1.60) in Southern Europe and 0.93 (0.66 to 1.31) in Eastern Europe. Women who were single mothers before age 20, for 8+ years, or resulting from divorce or non-marital childbearing, were at particular risk. Single motherhood during early-adulthood or mid-adulthood is associated with poorer health in later life. Risks were greatest in England, the USA and Scandinavia. Selection and causation mechanisms might both explain between-country variation. Published by the BMJ Publishing Group Limited.

Distrust in the American healthcare system is common among Afro-Caribbeans but the role of this distrust in conflict over life-sustaining treatment is not well described. To identify the ways that distrust manifests in ethics committee consultation for conflict over life-sustaining treatment among Afro-Caribbean patients. This was a retrospective cohort study at a large academic hospital of all ethics committee consultations for life-sustaining treatment among Afro-Caribbean patients and their surrogates. We reviewed medical records and identified cases in which ethics consultants described distrust as playing a role in the conflict over life-sustaining treatment. Of the 169 ethics committee consultation cases for conflict over life-sustaining treatment, 11 (6.5%) involved patients who self-identified as Afro-Caribbean. Distrust played a role in several of these cases, with surrogates of three patients, in particular, illustrating the way that perceived heath disparities, past labelling and concerns about continued maltreatment generated distrust leading to conflict over life-sustaining treatment. Exploring issues of distrust may help ethics consultants identify the source of conflict over life-sustaining treatment among Afro-Caribbean patients. Published by the BMJ Publishing Group Limited.

Background Most self-pollinating plants are annuals. According to the 'time-limitation' hypothesis, this association between selfing and the annual life cycle has evolved as a consequence of strong r-selection, involving severe time-limitation for completing the life cycle. Under this model, selection from frequent density-independent mortality in ephemeral habitats minimizes time to flower maturation, with selfing as a trade-off, and / or selection minimizes the time between flower maturation and ovule fertilization, in which case selfing has a direct fitness benefit. Predictions arising from this hypothesis were evaluated using phylogenetically-independent contrasts of several life history traits in predominantly selfing versus outcrossing annuals from a data base of 118 species distributed across 14 families. Data for life history traits specifically related to maturation and pollination times were obtained by monitoring the start and completion of different stages of reproductive development in a greenhouse study of selfing and outcrossing annuals from an unbiased sample of 25 species involving five pair-wise family comparisons and four pair-wise genus comparisons. Results Selfing annuals in general had significantly shorter plant heights, smaller flowers, shorter bud development times, shorter flower longevity and smaller seed sizes compared with their outcrossing annual relatives. Age at first flower did not differ significantly between selfing and outcrossing annuals. Conclusions This is the first multi-species study to report these general life-history differences between selfers and outcrossers among annuals exclusively. The results are all explained more parsimoniously by selection associated with time-limitation than by selection associated with pollinator/mate limitation. The shorter bud development time reported here for selfing annuals is predicted explicitly by the time-limitation hypothesis for the fitness benefit of selfing (and not by the alternative 'reproductive assurance' hypothesis associated with pollinator/mate limitation). Support for the time-limitation hypothesis is also evident from published surveys: whereas selfers and outcrossers are about equally represented among annual species as a whole, selfers occur in much higher frequencies among the annual species found in two of the most severely time-limited habitats where flowering plants grow – deserts and cultivated habitats.

There is insufficient evidence to guide decisions around (non-)disclosure of bad news of life-limiting illness and death to people with intellectual disabilities. The aim of this study was to develop guidelines for decisions about (non-)disclosure of bad news around life-limiting illness and death to people with intellectual disabilities, by examining stakeholders' preferences (and reasons) around disclosure and non-disclosure. Focus groups and interviews were held with 109 participants: people with intellectual disabilities, family carers, intellectual disabilities professionals and medical healthcare professionals. People with intellectual disabilities had wide-ranging views about disclosure. Reasons for non-disclosure included: preventing distress; too difficult for the bearer of bad news; the bearer of bad news lacks knowledge; inability to understand; no sense of time; conflicting views among stakeholders. Reasons for disclosure included: a right to know; knowledge helps the person cope; need for involvement. Disclosure of bad news could cause harm in some situations, but this needs careful assessment. The authors present guidelines for disclosure that now need to be tested in practice. © 2013 Blackwell Publishing Ltd.
Gelatinous drop-like corneal dystrophy: a review.

2017-01-01
Gelatinous drop-like corneal dystrophy (GDLD) is a rare autosomal recessive form of corneal dystrophy characterised by subepithelial and stromal amyloid deposits. It is relatively common in Japan. It usually presents in the first two decades of life with subepithelial nodular lesions that later coalesce to form mulberry-like opacities. Although various surgical modalities have been attempted, recurrence remains a major challenge. Published by the BMJ Publishing Group Limited.

Satisfaction with life domains in people with epilepsy.
Kobau, Rosemarie; Luncheon, Cecily; Zack, Matthew M; Shegog, Ross; Price, Patricia H
2012-12-01
While commonly used quality-of-life instruments assess perceived epilepsy-associated limitations in life domains and formally document patient concerns, less is known of community-dwelling adults with epilepsy about their satisfaction with broader life domains, such as satisfaction with housing, education, neighborhood, ability to help others, and achievement of goals. The purpose of this study was to examine satisfaction with life domains in a representative sample of community-dwelling adults with self-reported epilepsy from the 2008 HealthStyles survey. Following adjustment for sex, age group, race/ethnicity, education, and income, people with epilepsy were more likely to report frustration in the domains of achievement (e.g., dissatisfaction with education and life goals), compromised social interactions (dissatisfaction with family life, friends, and social life), and compromised physical capability (dissatisfaction with health and energy level). Life satisfaction and other well-being domains can supplement health indicators to guide treatment and program services for people with epilepsy to maximize their well-being.

Sensory shelf-life limiting factor of high hydrostatic pressure processed avocado paste.
Jacobo-Velázquez, D A; Hernández-Brenes, C
2011-08-01
High hydrostatic pressure (HHP) processing pasteurizes avocado paste without a significant impact on flavor. Although HHP-treated avocado paste stored under refrigeration is safe for human consumption for months, sensory changes taking place during storage cause the rejection of the product by consumers within days. Although it is known that the shelf life of the product ends before its microbial counts are high, its sensory shelf life limiting factor remains unknown. The present study focused on the use of a trained panel and a consumer panel to determine the sensory shelf life limiting factor of HHP-treated avocado paste. The trained panel identified sour and rancid flavors as the main sensory descriptors (critical descriptors) that differentiated stored from freshly processed samples. Further data obtained from consumers identified sour flavor as the main cause for a significant decrease in the acceptability (shelf life limiting factor) of refrigerated HHP-treated avocado paste. The study allowed the elucidation of a proposed deterioration mechanism for HHP-treated avocado paste during its refrigerated shelf life. The information through this work enhances scientific knowledge of the product and proposes the sour flavor development during storage as a relevant sensory attribute that needs to be improved in order to enhance the product shelf life. At present, HHP is the most effective commercial nonthermal technology to process avocado paste when compared to thermal and chemical alternatives. HHP-treated avocado paste is a microbiologically stable food for a period of at least 45 d stored under refrigeration. However, previous published work indicated that consumers rejected the product after approximately 19 d of storage due to sensory changes. This manuscript presents a sensory study that permitted the identification of the critical sensory descriptor that is acting as the sensory shelf life limiting factor of the product. The data presented herein along with previous reported data allows a better understanding of the deterioration mechanism that occurs during the storage of HHP-treated avocado paste. This information is relevant and useful for the elucidation of possible alternatives to enhance the shelf life of HHP-treated avocado paste. © 2011 Institute of Food Technologists®
[Chances and limitations of patients' advance decisions at the end of life].
Bauer, Axel W
2009-01-01
Death by "natural" causes is not appreciated in Western industrialized countries because it may be regarded as an obstacle against performance and consumption. In addition, life-saving therapies for patients with an infaust prognosis are often rather expensive and therefore classified as "futile". Utilitarian measures for the individual's quality of life (QALY's), which are allegedly objective, veil the fact that they can only reflect the parameters that have been considered during their construction. Caused by fear of a life in the nursing home, which is partially intensified by the media, many ethicists and lawyers propagate anticipating models of retaining patients' autonomy at the end of life. Apart from general considerations published by the former National Ethics Council in 2005, the German Parliament in 2009 will have to discuss three different bills concerning patients' advance decisions to refuse medical treatment. The illusion of "autonomous dying" is not a convincing model for the end of life debate.
Is procreative beneficence obligatory?
Saunders, Ben
2015-02-01
Julian Savulescu defends the principle of procreative beneficence, according to which parents have a prima facie moral obligation to choose the child with the best expected life. In this paper, I argue that Savulescu fails to show that procreative beneficence is genuinely obligatory, because of his equivocation between moral reason and moral obligation. Savulescu assumes that morality requires us to do what we have most (moral) reason to do, but many deny this, for instance because they believe we have reasons (but no obligation) to perform supererogatory actions. Even if parents have moral reasons to choose the child with the best expected life, they may not be under any obligation to do so. Published by the BMJ Publishing Group Limited.

Posttraumatic stress disorder (PTSD) is a leading cause of impairments in quality of life and functioning among Veterans. Service dogs have been promoted as an effective adjunctive intervention for PTSD, however published research is limited and design and implementation flaws in published studies limit validated conclusions. This paper describes the rationale for the study design, a detailed methodological description, and implementation challenges of a multisite randomized clinical trial examining the impact of service dogs on the on the functioning and quality of life of Veterans with PTSD. Trial design considerations prioritized participant and intervention (dog) safety, selection of an intervention comparison group that would optimize enrollment in all treatment arms, pragmatic methods to ensure healthy well-trained dogs, and the selection of outcomes for achieving scientific and clinical validity in a Veteran PTSD population. Since there is no blueprint for conducting a randomized clinical trial examining the impact of dogs on PTSD of this size and scope, it is our primary intent that the successful completion of this trial will set a benchmark for future trial design and scientific rigor, as well as guiding researchers aiming to better understand the role that dogs can have in the management of Veterans experiencing mental health conditions such as PTSD.

Physical occupational exposures and health expectancies in a French occupational cohort.

2017-03-01
To examine the relationships of strenuous and hazardous working conditions and rotating shifts that involve night working with life expectancy in good perceived health and life expectancy without chronic disease. The sample contained male gas and electricity workers from the French GAZEL cohort (n=13 393). Six measures of physical working conditions were examined: Self-reports from 1989 and 1990 of ergonomic strain, physical danger, rotating shifts that involve night working and perceived physical strain; company records of workplace injuries and a job-exposure matrix of chemical exposures. Partial healthy life expectancies (age 50-75) relating to (1) self-rated health and (2) chronic health conditions, obtained from annual questionnaires (1989-2014) and company records, were estimated using multistate life tables. The analyses were adjusted for social class and occupational grade. Participants with physically strenuous jobs and who had experienced industrial injuries had shorter partial life expectancy. More physically demanding and dangerous work was associated with fewer years of life spent in good self-rated health and without chronic conditions, with the exception of shift work including nights, where the gradient was reversed. Strenuous and hazardous work may contribute to lost years of good health in later life, which has implications for individuals' quality of life as well as healthcare use and labour market participation.

In a meta-analysis published by myself and co-authors, we report differences in the life history risk factors for estrogen receptor negative (ER-) and estrogen receptor positive (ER+) breast cancers. Our meta-analysis did not find the association of ER- breast cancer risk with fast life history characteristics that Hidaka and Boddy suggest in their response to our article. There are a number of possible explanations for the differences between their conclusions and the conclusions we drew from our meta-analysis, including limitations of our meta-analysis and methodological challenges in measuring and categorizing estrogen receptor status. These challenges, along with the association of ER+ breast cancer with slow life history characteristics, may make it challenging to find a clear signal of ER- breast cancer with fast life history characteristics, even if that relationship does exist. The contradictory results regarding breast cancer risk and life history characteristics illustrate a more general challenge in evolutionary medicine: often different sub-theories in evolutionary biology make contradictory predictions about disease risk. In this case, life history models predict that breast cancer risk should increase with faster life history characteristics, while the evolutionary mismatch hypothesis predicts that breast cancer risk should increase with delayed reproduction. Whether life history tradeoffs contribute to ER- breast cancer is still an open question, but current models and several lines of evidence suggest that it is a possibility. © The Author(s) 2016.

Ethics and end of life care: the Liverpool Care Pathway and the Neuberger Review.
Wrigley, Anthony
2015-08-01
The Liverpool Care Pathway for the Dying has recently been the topic of substantial media interest and also been subject to the independent Neuberger Review. This review has identified clear failings in some areas of care and recommended the Liverpool Care Pathway be phased out. I argue that while the evidence gathered of poor incidences of practice by the Review is of genuine concern for end of life care, the inferences drawn from this evidence are inconsistent with the causes for the concern. Seeking to end an approach that is widely seen as best practice and which can genuinely deliver high quality care because of negative impressions that have been formed from failing to implement it properly is not a good basis for radically overhauling our approach to end of life care. I conclude that improvements in training, communication and ethical decision-making, without the added demand to end the Liverpool Care Pathway, would have resulted in a genuine advance in end of life care.

Oxygen supply limits the heat tolerance of lizard embryos.
Smith, Colton; Telemeco, Rory S; Angilletta, Michael J; VandenBrooks, John M
2015-04-01
The mechanisms that set the thermal limits to life remain uncertain. Classically, researchers thought that heating kills by disrupting the structures of proteins or membranes, but an alternative hypothesis focuses on the demand for oxygen relative to its supply. We evaluated this alternative hypothesis by comparing the lethal temperature for lizard embryos developing at oxygen concentrations of 10-30%. Embryos exposed to normoxia and hyperoxia survived to higher temperatures than those exposed to hypoxia, suggesting that oxygen limitation sets the thermal maximum. As all animals pass through an embryonic stage where respiratory and cardiovascular systems must develop, oxygen limitation may limit the thermal niches of terrestrial animals as well as aquatic ones. © 2015 The Author(s) Published by the Royal Society.

In this essay I examine the formal structure of the concept of futility, enabling identification of the appropriate roles played by patient, professional, and society. I argue that the concept of futility does not justify unilateral decisions to forego life-sustaining medical treatment over patient or legitimate surrogate objection, even when futility is determined by a process or subject to ethics committee review. Furthermore, I argue for a limited positive ethical obligation on the part of health care professionals to assist patients in achieving certain restricted goals, including the preservation of life, even in circumstances in which most would agree that that life is of no benefit to the patient. Finally, I address the objection that professional integrity overrides this limited obligation and find the objection unconvincing. In short, my aim in this essay is to see the concept of futility finally buried, once and for all. © The Author 2015.

Functional Status, Cognition, and Social Relationships in Dyadic Perspective.
Wong, Jaclyn S; Hsieh, Ning
2017-03-28
Health limitations can change older adults' social relationships and social engagement. Yet, researchers rarely examine how the disability of one's spouse might affect one's social relationships, even though such life strains are often experienced as a couple. This study investigates the association between functional and cognitive limitations and social experience in a dyadic context. We use actor-partner interdependence models to analyze the partner data from 953 heterosexual couples in Wave II (2010-2011) of the National Social Life, Health, and Aging Project. One spouse's functional and cognitive health is associated with the other's relationship quality, but the pattern varies by gender. Husbands' functional limitations are associated with lower marital support and higher marital strain in wives, but wives' functional limitations are related to lower family and friendship strain in husbands. Husbands' cognitive impairment also predicts higher family and friend support in wives. Findings support a gendered dyadic relationship between health and social life and highlight women's caregiver role and better connection with family and friends. There are also differences between experiencing cognitive and physical limitations in couples. Finally, mild health impairment sometimes shows stronger effects on social relationships than severe impairment, suggesting adaptation to health transition. © The Author 2017.

Previous studies have found generally better health among those who combine employment and family responsibilities; however, most research excludes men, and relies on subjective measures of health and information on work and family activities from only 1 or 2 time points in the life course. This study investigated associations between work-family life course types (LCTs) and markers of metabolic risk in a British birth cohort study. Multichannel sequence analysis was used to generate work-family LCTs, combining annual information on work, partnership and parenthood between 16 and 42 years for men and women in the British National Child Development Study (NCDS, followed since their birth in 1958). Associations between work-family LCTs and metabolic risk factors in mid-life (age 44-45) were tested using multivariate linear regression in multiply imputed data. Life courses characterised by earlier transitions into parenthood were associated with significantly increased metabolic risk, regardless of attachment to paid work or marital stability over the life course. These associations were only partially attenuated by educational qualifications, early life circumstances and adult mediators. The positive association between weak labour markets ties and metabolic risk was weaker than might be expected from previous studies. Associations between work-family LCTs and metabolic risk factors did not differ significantly by gender. Earlier transitions to parenthood are linked to metabolic risk in mid-life.

Coping with arthritis-related stress has been extensively studied. However, limited evidence exists regarding coping with stress extraneous to the disease (life stress). This study explored life stress and coping in a subset of older women with osteoarthritis from a larger longitudinal study. An Australian regional university. This qualitative study involved semistructured telephone interviews. Potential participants were mailed a letter of invitation/participant information statement by the Australian Longitudinal Study on Women's Health (ALSWH). Invitations were sent out in small batches (primarily 10). Interviews were conducted until data saturation was achieved using a systematic process (n=19). Digitally recorded interviews were transcribed verbatim and deidentified. Data were thematically analysed. Women who indicated being diagnosed or treated for arthritis in the previous 3 years in the fifth survey of the ALSWH (conducted in 2007) provided the sampling frame. Potential participants were randomly sampled by a blinded data manager using a random number generator. Coping with life stress involved both attitudinal coping processes developed early in life (ie, stoicism) and transient cognitive and support-based responses. Women also described a dualistic process involving a reduction in the ability to cope with ongoing stress over time, coupled with personal growth. This is the first study to examine how individuals cope with non-arthritis-related stress. The findings add to the current understanding of stress and coping, and have implications regarding the prevention of arthritis in women. Importantly, this study highlighted the potential detrimental impact of persistent coping patterns developed early in life. Public health campaigns aimed at stress mitigation and facilitation of adaptive coping mechanisms in childhood and adolescence may assist with arthritis prevention.

The European Academy of Allergy and Clinical Immunology (EAACI) is in the process of developing the EAACI Guidelines on Allergen Immunotherapy (AIT) for the management of insect venom allergy. To inform this process, we sought to assess the effectiveness, cost-effectiveness and safety of AIT in the management of insect venom allergy. We undertook a systematic review, which involved searching 15 international biomedical databases for published and unpublished evidence. Studies were independently screened and critically appraised using established instruments. Data were descriptively summarized and, where possible, meta-analysed. Our searches identified a total of 16 950 potentially eligible studies; of which, 17 satisfied our inclusion criteria. The available evidence was limited both in volume and in quality, but suggested that venom immunotherapy (VIT) could substantially reduce the risk of subsequent severe systemic sting reactions (OR = 0.08, 95% CI 0.03-0.26); meta-analysis showed that it also improved disease-specific quality of life (risk difference = 1.41, 95% CI 1.04-1.79). Adverse effects were experienced in both the build-up and maintenance phases, but most were mild with no fatalities being reported. The very limited evidence found on modelling cost-effectiveness suggested that VIT was likely to be cost-effective in those at high risk of repeated systemic sting reactions and/or impaired quality of life. The limited available evidence suggested that VIT is effective in reducing severe subsequent systemic sting reactions and in improving disease-specific quality of life. VIT proved to be safe and no fatalities were recorded in the studies included in this review. The cost-effectiveness of VIT needs to be established. © 2016 The Authors.

PA2 Satisfaction with information received: perceptions of the patient and the informal caregiver.

Provision of information to patients and families is a priority of palliative care. Lack of information on symptoms, treatment and disease progress adversely affects patients' and caregivers' abilities to self manage and participate in decision making and care. Qualitative reports of end of life care suggest caregivers seek more information than patients. Ignorance of this need may hamper health promotion strategies and limitation of patient and caregiver morbidity during end of life and bereavement processes. To compare satisfaction of dying patients with information given; to proxy satisfaction estimates on the patient's behalf. Prospective study comparing assessment of satisfaction with information received by nurse, informal caregiver and dying patient (>64 years) in hospital. Assessments made within 24 h, using patient and caregiver versions of the palliative outcome scale (POS). weighted kappa for agreement between proxy and patient. Informal caregivers overestimate dissatisfaction with level of information given compared to patients. Weighted kappa patient versus ICG 0.187 (slight agreement), n = 50. The disparity between patient and proxy information satisfaction reflects the complexity of participatory strategies to limit morbidity at the end of life. Proxy over- estimation of patient dissatisfaction with information received may reflect the caregivers own dissatisfaction. As death approaches, caregivers require more information than patients, their burden increases and they become the interpreter of patient symptoms. Ignorance may lead to overestimation of symptoms, early breakdown of social care, and unplanned admission, risking death other than in the patients preferred place. Meeting caregiver information needs may reduce caregiver burden and improve proxy assessments, reducing patient and caregiver morbidity. © 2015, Published by the BMJ Publishing Group Limited.

Preparing patients with cancer who work and treatment responsiveness.
Kamau, Caroline
2017-03-01
Many patients with life-limiting illnesses continue to work because of financial reasons and because work provides good psychosocial support. A lack of appropriate advice/support through patient education could, however, make having a job detrimental to well-being (eg, symptom worsening). This study investigated the frequency with which patients received information that empowers their understanding of their condition, treatment, side effects of treatment and the likely impact on occupational functioning. A cross-sectional study. An analysis of survey data from 3457 patients with cancer in employment. Logistic regression showed that patients who received information about the impact of cancer on work life or education are 1.72 times more likely to have a positive treatment outcome. Patients who receive written information about the type of cancer are 1.99 times more likely to have a positive treatment outcome. Also, patients who receive written information before a cancer-related operation are 1.90 times more likely to have a positive treatment outcome. Information about the side effects of cancer treatment produces worse odds of a positive treatment outcome (0.65-1). A stepwise logistic regression analysing the effects irrespective of current employment status in 6710 patients showed that preparing them produces nearly twice better odds of cancer treatment responsiveness. Palliative care teams should consider ways of actively advising patients who work. Whereas the results showed evidence of good practice in cancer care, there is a need to ensure that all working patients with potentially life-limiting illnesses receive similar support.

To understand patients and family caregivers' experiences with home palliative care services, in order to identify, explore and integrate the key components of care that shape the experiences of service users. We performed a meta-ethnography of qualitative evidence following PRISMA recommendations for reporting systematic reviews. The studies were retrieved in 5 electronic databases (MEDLINE, EMBASE, PsycInfo, BNI, CINAHL) using 3 terms and its equivalents ('Palliative', 'Home care', 'Qualitative research') combined with 'AND', complemented with other search strategies. We included original qualitative studies exploring experiences of adult patients and/or their family caregivers (≥18 years) facing life-limiting diseases with palliative care needs, being cared for at home by specialist or intermediate home palliative care services. 28 papers reporting 19 studies were included, with 814 participants. Of these, 765 were family caregivers and 90% were affected by advanced cancer. According to participants' accounts, there are 2 overarching components of home palliative care: presence (24/7 availability and home visits) and competence (effective symptom control and skilful communication), contributing to meet the core need for security. Feeling secure is central to the benefits experienced with each component, allowing patients and family caregivers to focus on the dual process of living life and preparing death at home. Home palliative care teams improve patients and caregivers experience of security when facing life-limiting illnesses at home, by providing competent care and being present. These teams should therefore be widely available and empowered with the resources to be present and provide competent care. Published by the BMJ Publishing Group Limited.

This analysis investigated the relationships between healthcare expenditures in the last 6 months of life and use of general practitioner (GP) services in the preceding 12-month period among older residents of New South Wales, Australia. Questionnaire data (2006-2009) for more than 260,000 people aged 45 years and over were linked to individual hospital and death records and cost data. For 14,819 participants who died during follow-up, generalised linear mixed models were used to explore the relationships between costs of hospital, emergency department (ED) and Medicare-funded outpatient and pharmaceutical services in the last 6 months of life, and quintile of GP use in the 18-7 months before death. Analyses were adjusted for age at death, sex, educational level, language, private health insurance, household income, self-reported health status, functional limitation, psychological distress, number of comorbidities and geographic clustering. Almost 85% of decedents had at least one hospitalisation in the last 6 months, and the mean (median) of total cost for each person in this period was $A20,453 (14,835). There was no significant difference in the hospital cost, including cost for preventable hospitalisations in the last 6 months of life, across quintiles of GP use in the 18-7 months before death. Participants in the lowest quintile of GP use incurred more ED costs, but ED costs were similar across the other quintiles of GP use. Costs for Medicare-funded outpatient services and pharmaceuticals increased steeply according to quintile of GP use. In the Australian setting, there was no association between use of GP services in the 18-7 months before death and hospital costs in the last 6 months, but there was significant association with higher costs for outpatient services and pharmaceuticals. However, there was some indication that limited GP access might be associated with increased ED use at end of life. Published by the BMJ Publishing Group Limited.

Hashimoto thyroiditis (HT) and other benign goiters (BG) might influence patients' quality of life (QoL). The objective of this study was to analyze influence of surgery on these patients' QoL. A prospective cohort study was conducted. The ThyPRO questionnaire was used in the QoL assessment. The HT patients experienced significantly worse hypothyroid symptoms and sex life than the BG patients. The improvement in QoL in the BG patients was significant after surgery in all ThyPRO domains. In the HT patients, the improvement was significant in all but two domains, eye symptoms and cognitive impairment. The best improvement in both groups was in overall QoL. None of the patients developed permanent consequences. The QoL of HT and BG patients is impaired and improves significantly after surgical treatment. Thyroidectomy should be considered as a treatment option in the HT patients more often as in the BG patients. Copyright © 2015 IJS Publishing Group Limited. Published by Elsevier Ltd.

Social support is associated with better health. However, only a limited number of studies have examined the association of social support with health from the adult life course perspective and whether this association is bidirectional. Participants (n=6797; 30% women; age range from 40 to 77 years) who were followed from 1989 (phase 2) to 2006 (phase 8) were selected from the ongoing Whitehall II Study. Structural and functional social support was measured at follow-up phases 2, 5 and 7. Mental and physical health was measured at five consecutive follow-up phases (3-8). Social support predicted better mental health, and certain functional aspects of social support, such as higher practical support and higher levels of negative aspects in social relationships, predicted poorer physical health. The association between negative aspects of close relationships and physical health was found to strengthen over the adult life course. In women, the association between marital status and mental health weakened until the age of approximately 60 years. Better mental and physical health was associated with higher future social support. The strength of the association between social support and health may vary over the adult life course. The association with health seems to be bidirectional. Published by the BMJ Publishing Group Limited.

Current recommendations for physical activity in children overlook the critical importance of motor skill acquisition early in life. Instead, they focus on the quantitative aspects of physical activity (eg, accumulate 60 min of daily moderate to vigorous physical activity) and selected health-related components of physical fitness (eg, aerobic fitness, muscular strength, muscular endurance, flexibility and body composition). This focus on exercise quantity in youth may limit considerations of qualitative aspects of programme design which include (1) skill development, (2) socialisation and (3) enjoyment of exercise. The timing of brain development and associated neuroplasticity for motor skill learning makes the preadolescence period a critical time to develop and reinforce fundamental movement skills in boys and girls. Children who do not participate regularly in structured motor skill-enriched activities during physical education classes or diverse youth sports programmes may never reach their genetic potential for motor skill control which underlies sustainable physical fitness later in life. The goals of this review are twofold: (1) challenge current dogma that is currently focused on the quantitative rather than qualitative aspects of physical activity recommendations for youth and (2) synthesise the latest evidence regarding the brain and motor control that will provide the foundation for integrative exercise programming that provide a framework sustainable activity for life.

While there are many published studies on HIV and functional limitations, there are few in the context of early abuse and its impact on functionality and Quality of Life (QoL) in HIV. The present study focused on HIV in the context of childhood trauma and its impact on functionality and Quality of Life (QoL) by evaluating 85 HIV-positive (48 with childhood trauma and 37 without) and 52 HIV-negative (21 with childhood trauma and 31 without) South African women infected with Clade C HIV. QoL was assessed using the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q), the Patient's Assessment of Own Functioning Inventory (PAOFI), the Activities of Daily Living (ADL) scale and the Sheehan Disability Scale (SDS). Furthermore, participants were assessed using the Center for Epidemiologic Studies Depression Scale (CES-D) and the Childhood Trauma Questionnaire (CTQ). Subjects had a mean age of 30.1 years. After controlling for age, level of education and CES-D scores, analysis of covariance (ANCOVA) demonstrated significant individual effects of HIV status and childhood trauma on self-reported QoL. No significant interactional effects were evident. Functional limitation was, however, negatively correlated with CD4 lymphocyte count. In assessing QoL in HIV-infected women, we were able to demonstrate the impact of childhood trauma on functional limitations in HIV.

The social gradient in smoking is well known, with higher rates among those in less advantaged socioeconomic position. Some recent research has reported that personality characteristics partly explain this gradient. However, the majority of existing work is limited by cross-sectional designs unsuitable to determine whether differences in conscientiousness are a predictor or a product of social inequalities. Adopting a life course perspective, we investigated in the current paper the influence of conscientiousness in early and mid-life on the social gradient in smoking and the role of potential confounding factors in a large longitudinal cohort study. Using data from the 1958 National Child Development Study, we examined the extent to which two measures of conscientiousness, one assessed with a personality questionnaire at age 50 and one derived from three related items at 16 years in childhood, explained the social gradient of smoking at age 50 by comparing nested logistic regression models that included social class at birth, cognitive ability, attention and conduct problems at age 7, and educational qualification. Childhood conscientiousness was a significant predictor of smoking at 50 years (OR=0.86, CI (95%) 0.84 to 0.88), explaining 5.0% of the social gradient independent of all other variables. Childhood conscientiousness was a stronger predictor than adult conscientiousness, statistically accounting for the observed direct association of adult conscientiousness with smoking. Conscientiousness may be a predictor rather than a product of social differences in smoking. Inclusion of personality measures and adoption of a life course perspective add significantly to our understanding of health inequalities. Published by the BMJ Publishing Group Limited.

This research aims to provide a better understanding of the experience of support workers, as paid carers, caring for adults with learning disabilities (LDs) nearing the end of life in residential settings. In the past 100 years, people with LDs (also referred to as 'learning difficulty', 'mental retardation' and 'intellectual disability' internationally) are living longer with life expectancy approaching the population norm and more likely to die from diseases such as cancer, respiratory and vascular diseases. Community-based supported accommodation has become the foremost provider for people with LDs in their late 30 s or over in the UK. In the midst of the transition from living to dying for people with LDs, and even postdeath, the needs of support workers are often neglected against a background where most are unqualified, often with little experience of death and dying event, and with limited access to clinical supervision and education. 3 focus groups involving 13 support workers were conducted at 3 independent service provider settings for people with LDs in London. In recounting the experiences of these groups of support workers, 6 themes are described: strong emotional bond and identification; collaboration with other services; training issues around the extended role; support within the organisation; relationship with family/other residents; and grieving the 'loss'. Although support workers play a key role in meeting the end-of-life care needs of people with LDs in residential settings, their own needs are often neglected. There are still significant gaps in understanding these needs and practice development in this area. Published by the BMJ Publishing Group Limited.

Dietary changes which improve health are also likely to be beneficial for the environment by reducing emissions of greenhouse gases (GHG). However, previous analyses have not accounted for the potential acceptability of low GHG diets to the general public. This study attempted to quantify the health effects associated with adopting low GHG emission diets in the UK. Epidemiological modelling study. UK. UK population. Adoption of diets optimised to achieve the WHO nutritional recommendations and reduce GHG emissions while remaining as close as possible to existing dietary patterns. Changes in years of life lost due to coronary heart disease, stroke, several cancers and type II diabetes, quantified using life tables. If the average UK dietary intake were optimised to comply with the WHO recommendations, we estimate an incidental reduction of 17% in GHG emissions. Such a dietary pattern would be broadly similar to the current UK average. Our model suggests that it would save almost 7 million years of life lost prematurely in the UK over the next 30 years and increase average life expectancy by over 8 months. Diets that result in additional GHG emission reductions could achieve further net health benefits. For emission reductions greater than 40%, improvements in some health outcomes may decrease and acceptability will diminish. There are large potential benefits to health from adopting diets with lower associated GHG emissions in the UK. Most of these benefits can be achieved without drastic changes to existing dietary patterns. However, to reduce emissions by more than 40%, major dietary changes that limit both acceptability and the benefits to health are required. Published by the BMJ Publishing Group Limited.

Clinically assisted hydration and the Liverpool Care Pathway: Catholic ethics and clinical evidence.
Nowarska, Anna
2015-08-01
The Liverpool Care Pathway for the Dying Patient (LCP), a framework introduced for providing comfortable care at the last stage of life, has recently become highly contentious. Among the most serious allegations levelled against it, has been that the LCP may be used as a covert form of euthanasia by withdrawal of clinically assisted hydration (CAH). This concern has been raised, in particular by a number of Catholic medical professionals, who have asserted that the LCP is incompatible with Catholic ethics. This paper examines the key Catholic ethical principles relevant to treatment and care towards the end of life (the sanctity/inviolability of life principle, the distinction between ordinary and extraordinary means). Relevant current clinical evidence regarding CAH in relation to terminal thirst, dehydration, prolongation of life and possible negative impacts on the dying is also scrutinised. It is argued that for some patients at the very end of life it may be permissible and even desirable to withhold or withdraw it. Thus, as administration of CAH may become extraordinary, forgoing it in some situations is fully compatible with Catholic ethics. The article therefore concludes that the stance of the LCP in respect of provision of CAH is fully in alignment with Catholic teaching. Published by the BMJ Publishing Group Limited.

Life histories predict coral community disassembly under multiple stressors.
Darling, Emily S; McClanahan, Timothy R; Côté, Isabelle M
2013-06-01
Climate change is reshaping biological communities against a background of existing human pressure. Evaluating the impacts of multiple stressors on community dynamics can be particularly challenging in species-rich ecosystems, such as coral reefs. Here, we investigate whether life-history strategies and cotolerance to different stressors can predict community responses to fishing and temperature-driven bleaching using a 20-year time series of coral assemblages in Kenya. We found that the initial life-history composition of coral taxa largely determined the impacts of bleaching and coral loss. Prior to the 1998 bleaching event, coral assemblages within no-take marine reserves were composed of three distinct life histories - competitive, stress-tolerant and weedy- and exhibited strong declines following bleaching with limited subsequent recovery. In contrast, fished reefs had lower coral cover, fewer genera and were composed of stress-tolerant and weedy corals that were less affected by bleaching over the long term. Despite these general patterns, we found limited evidence for cotolerance as coral genera and life histories were variable in their sensitivities to fishing and bleaching. Overall, fishing and bleaching have reduced coral diversity and led to altered coral communities of 'survivor' species with stress-tolerant and weedy life histories. Our findings are consistent with expectations that climate change interacting with existing human pressure will result in the loss of coral diversity and critical reef habitat. © 2013 Blackwell Publishing Ltd.

Psychologist B. F. Skinner developed and promoted a technology of behavior as the basis for widespread social reform over much of his career. In 1948, he published his behaviorally engineered vision of the good life in his utopian novel Walden Two (Skinner, 1948). Skinner's efforts were part of a much larger social engineering tradition that received one of its fullest expressions in the Technocracy Movement of the 1930s. Fifteen years before Skinner's Walden Two , at the height of the Technocracy Movement's public visibility in the United States, technocrat Harold Loeb (1933/1996) published his utopia, Life in a Technocracy: What It Might Be Like . In this article, I place the socially engineered visions of the good life promoted by the Technocracy Movement and by Skinner on an intellectual and ideological continuum to amplify and explore American attitudes toward psychology, technology, and social engineering during the middle decades of the 20th century. I argue that responses to both reveal the possibilities and limits of the social engineering enterprise, and suggest that historians of technology might consider how the history of psychology and other psy-disciplines can deepen conceptualizations of the relationships among the psychological, the social, and the technological in this period.

Previous research has highlighted the importance of accumulated life-course labour market status and the balancing of multiple roles for understanding inequalities in health in later life. This may be particularly important for women, who are increasingly required to balance work and family life in liberal welfare contexts, such as in Britain. This study analyses retrospective life history data for 2160 women aged 64+ years (born 1909-1943) from the English Longitudinal Study of Ageing, collected in 2006-2007 as part of an ongoing panel study. Optimal matching and cluster analyses are used to produce a taxonomy of women's life-course economic activity trajectories based on their experiences between ages 16 and 64 years. This classification is then used in logistic regression analysis to investigate associations with self-rated health in later life. A set of five trajectories emerge as the dominant patterns of women's economic activity over the life course for those cohorts of English women born prior to 1943: (1) full-time workers; (2) family carers; (3) full-time returners; (4) part-time returners; (5) atypical/inactive. Regression analyses show that women who experience defined periods of full-time work both before and after focusing on family life appear to have the most favourable later life health outcomes. The findings are discussed with reference to the accumulation of social and economic resources over the life course and the balancing of multiple roles in work and family domains. In conclusion, the development of policies that facilitate women, if they wish, to successfully combine paid employment with family life could have a positive impact on their health in later life.

Religious leaders are well respected in most Nigerian communities and are often called in to provide support for terminally-ill patients. Many Nigeria communities still view cancer as a stigmatised disease. This study sought to elicit the perceptions of Christian and Islamic religious leaders and explore problems associated with their involvement in end-of-life care for cancer patients. Participants were recruited among 114 religious leaders. Four focus group discussion sessions were then conducted with open-ended questions on previous involvement in end-of-life care of cancer patients and whether they would like to do more. There were thirty (30) willing participants in all. The discussions were audiotaped, transcribed and coded using the NUDIST software. Ninety of the respondents (62%) would not be involved in end-of-life care. This is because of the fear of peer pressure. The responses could be classified under three major themes were identified: (1) Care supposed to be provided by all religious leaders (2) End-of-Life care in institutions are safer (3) End-of-Life care consumes time. Statements made by respondents include "I will fall out with many if I am found ministering to dying patients". We observe that peer pressure played an important role in the acceptability of end-of-life activities in this group. This could be used in the positive light in designing interventions. © 2015, Published by the BMJ Publishing Group Limited.

In the first decade of the 21st century, the Mexican life expectancy changed from a long trend of increase to stagnation. These changes concur with an increase in deaths by homicides that the country experienced in that decade, and an obesity epidemic that had developed over the last decades of the 20th century. We quantify the impact of causes of death on life expectancy from 2000 to 2010. Two approaches to analyse causes of death are used: the number of life years lost due to each of the causes of death in a given year, and cause-decomposition techniques for comparisons of life expectancy from 2000 to 2010. The apparent stagnation in life expectancy is the result of an increase in deaths by homicides and diabetes mellitus on the one hand, and the positive improvements observed in other causes of death on the other. The negative impact of homicides is particularly observed for ages 15 and 50, and for that of diabetes mellitus at ages above 45 years. There is little basis for optimism regarding the future scenarios of the health of the Mexican population based on the first decade of the 21st century. Male life expectancy would have increased by 2 years if deaths by homicides and diabetes mellitus had been avoided. Published by the BMJ Publishing Group Limited.

The Limits on Trypanosomatid Morphological Diversity
Wheeler, Richard John; Gluenz, Eva; Gull, Keith
2013-01-01
Cell shape is one, often overlooked, way in which protozoan parasites have adapted to a variety of host and vector environments and directional transmissions between these environments. Consequently, different parasite life cycle stages have characteristic morphologies. Trypanosomatid parasites are an excellent example of this in which large morphological variations between species and life cycle stage occur, despite sharing well-conserved cytoskeletal and membranous structures. Here, using previously published reports in the literature of the morphology of 248 isolates of trypanosomatid species from different hosts, we perform a meta-analysis of the occurrence and limits on morphological diversity of different classes of trypanosomatid morphology (trypomastigote, promastigote, etc.) in the vertebrate bloodstream and invertebrate gut environments. We identified several limits on cell body length, cell body width and flagellum length diversity which can be interpreted as biomechanical limits on the capacity of the cell to attain particular dimensions. These limits differed for morphologies with and without a laterally attached flagellum which we suggest represent two morphological superclasses, the ‘juxtaform’ and ‘liberform’ superclasses. Further limits were identified consistent with a selective pressure from the mechanical properties of the vertebrate bloodstream environment; trypanosomatid size showed limits relative to host erythrocyte dimensions. This is the first comprehensive analysis of the limits of morphological diversity in any protozoan parasite, revealing the morphogenetic constraints and extrinsic selection pressures associated with the full diversity of trypanosomatid morphology.

The sudden death of Pablo Picasso's closest friend Carlos Casagemas in 1901 came as a great shock to the young Picasso. From a young age, Picasso had ruminated on life and death; however, this was his first experience of bereavement. Following the death of Casagemas, Picasso's paintings can be seen as a diary of his grieving process and clearly illustrate the five stages of the grieving process as outlined by Kubler-Ross in ' On Death and Dying ' (1969).

The pharmacokinetics (PK), safety and efficacy of BAY 81-8973, a full-length, unmodified, recombinant human factor VIII (FVIII), were evaluated in the LEOPOLD trials. The aim of this study was to develop a population PK model based on pooled data from the LEOPOLD trials and to investigate the importance of including samples with FVIII levels below the limit of quantitation (BLQ) to estimate half-life. The analysis included 1535 PK observations (measured by the chromogenic assay) from 183 male patients with haemophilia A aged 1-61 years from the 3 LEOPOLD trials. The limit of quantitation was 1.5 IU dL -1 for the majority of samples. Population PK models that included or excluded BLQ samples were used for FVIII half-life estimations, and simulations were performed using both estimates to explore the influence on the time below a determined FVIII threshold. In the data set used, approximately 16.5% of samples were BLQ, which is not uncommon for FVIII PK data sets. The structural model to describe the PK of BAY 81-8973 was a two-compartment model similar to that seen for other FVIII products. If BLQ samples were excluded from the model, FVIII half-life estimations were longer compared with a model that included BLQ samples. It is essential to assess the importance of BLQ samples when performing population PK estimates of half-life for any FVIII product. Exclusion of BLQ data from half-life estimations based on population PK models may result in an overestimation of half-life and underestimation of time under a predetermined FVIII threshold, resulting in potential underdosing of patients. © 2017 Bayer AG.

In 1956, Hans Selye tentatively suggested that the scientific study of stress could 'help us to formulate a precise program of conduct' and 'teach us the wisdom to live a rich and meaningful life'. Nearly two decades later, Selye expanded this limited vision of social order into a full-blown philosophy of life. In Stress without Distress , first published in 1974, he proposed an ethical code of conduct designed to mitigate personal and social problems. Basing his arguments on contemporary understandings of the biological processes involved in stress reactions, Selye referred to this code as 'altruistic egotism'. This article explores the origins and evolution of Selye's 'natural philosophy of life', analysing the links between his theories and adjacent intellectual developments in biology, psychosomatic and psychosocial medicine, cybernetics and socio-biology, and situating his work in the broader cultural framework of modern western societies.

We aimed to identify which personal and parental factors best explained all-cause mortality and cardiovascular disease (CVD). In 1996, data were collected on 2338 adult offspring of the participants in the 1972-1976 Renfrew and Paisley prospective cohort study. Recorded risk factors were assigned to 5 groups: mid-life biological and behavioural (BB), mid-life socioeconomic, parental BB, early-life socioeconomic and parental lifespan. Participants were followed up for mortality and hospital admissions to the end of 2011. Cox proportional hazards models were used to analyse how well each group explained all-cause mortality or CVD. Akaike's Information Criterion (AIC), a measure of goodness-of-fit, identified the most important groups. For all-cause mortality (1997 participants with complete data, 111 deaths), decreases in AIC from the null model (adjusting for age and sex) to models including mid-life BB, mid-life socioeconomic, parental BB, early-life socioeconomic and parental lifespan were 55.8, 21.6, 10.3, 7.3 and 5.9, respectively. For the CVD models (1736 participants, 276 with CVD), decreases were 37.8, 3.7, 6.7, 17.3 and 0.4. Mid-life BB factors were the most important for both all-cause mortality and CVD; mid-life socioeconomic factors were important for all-cause mortality, and early-life socioeconomic factors were important for CVD. Parental lifespan was the weakest factor. As mid-life BB risk factors best explained all-cause mortality and CVD, continued action to reduce these is warranted. Targeting adverse socioeconomic factors in mid-life and early life may contribute to reducing all-cause mortality and CVD risk, respectively. Published by the BMJ Publishing Group Limited.

For late-life neurocognitive disorders, as for other late-life chronic diseases, much recent interest has focused on the possible relevance of Developmental Origins of Health and Disease (DOHaD). Programming by undernutrition in utero, followed by overnutrition in adult life may lead to an increased risk, possibly mediated through cardiovascular and metabolic pathways. This study will specifically examine, if lower birth weight is associated with poorer cognitive functioning in late life in a south Indian population. From 1934 onwards, the birth weight, length and head circumference of all babies born in the CSI Holdsworth Memorial Hospital, Mysore, India, were recorded in obstetric notes. Approximately 800 men and women from the Mysore Birth Records Cohort aged above 55 years, and a reliable informant for each, will be asked to participate in a single cross-sectional baseline assessment for cognitive function, mental health and cardiometabolic disorders. Participants will be assessed for hypertension, type-2 diabetes and coronary heart disease, nutritional status, health behaviours and lifestyles, family living arrangements, economic status, social support and social networks. Additional investigations include blood tests (for diabetes, insulin resistance, dyslipidaemia, anaemia, vitamin B 12 and folate deficiency, hyperhomocysteinemia, renal impairment, thyroid disease and Apolipoprotein E genotype), anthropometry, ECG, blood pressure, spirometry and body composition (bioimpedance). We will develop an analysis plan, first using traditional univariate and multivariable analytical paradigms with independent, dependent and mediating/confounding/interacting variables to test the main hypotheses. This study has been approved by the research ethics committee of CSI Holdsworth Memorial Hospital. The findings will be disseminated locally and at international meetings, and will be published in open access peer reviewed journals. Published by the BMJ Publishing Group Limited.

There is an increasing number of new oncology drugs being studied, approved and put into clinical practice based on improvement in progression-free survival, when no overall survival benefits exist. In oncology, the association between progression-free survival and health-related quality of life is currently unknown, despite its importance for patients with cancer, and the unverified assumption that longer progression-free survival indicates improved health-related quality of life. Thus far, only 1 study has investigated this association, providing insufficient evidence and inconclusive results. The objective of this study protocol is to provide increased transparency in supporting a systematic summary of the evidence bearing on this association in oncology. Using the OVID platform in MEDLINE, Embase and Cochrane databases, we will conduct a systematic review of randomised controlled human trials addressing oncology issues published starting in 2000. A team of reviewers will, in pairs, independently screen and abstract data using standardised, pilot-tested forms. We will employ numerical integration to calculate mean incremental area under the curve between treatment groups in studies for health-related quality of life, along with total related error estimates, and a 95% CI around incremental area. To describe the progression-free survival to health-related quality of life association, we will construct a scatterplot for incremental health-related quality of life versus incremental progression-free survival. To estimate the association, we will use a weighted simple regression approach, comparing mean incremental health-related quality of life with either median incremental progression-free survival time or the progression-free survival HR, in the absence of overall survival benefit. Identifying direction and magnitude of association between progression-free survival and health-related quality of life is critically important in interpreting results of oncology trials. Systematic evidence produced from our study will contribute to improvement of patient care and practice of evidence-based medicine in oncology. Published by the BMJ Publishing Group Limited.

Learning From Leaders: Life-span Trends in Olympians and Supercentenarians.

Life-span trends progression has worldwide practical implications as it may affect the sustainability of modern societies. We aimed to describe the secular life-span trends of populations with a propensity to live longer-Olympians and supercentenarians-under two hypotheses: an ongoing life-span extension versus a biologic "probabilistic barrier" limiting further progression. In a study of life-span densities (total number of life durations per birth date), we analyzed 19,012 Olympians and 1,205 supercentenarians deceased between 1900 and 2013. Among most Olympians, we observed a trend toward increased life duration. This trend, however, decelerates at advanced ages leveling off with the upper values with a perennial gap between Olympians and supercentenarians during the whole observation period. Similar tendencies are observed among supercentenarians, and over the last years, a plateau attests to a stable longevity pattern among the longest-lived humans. The common trends between Olympians and supercentenarians indicate similar mortality pressures over both populations that increase with age, scenario better explained by a biologic "barrier" forecast. © The Author 2014.

Participants were 632 women and 410 men who had cognitive function tests (CFT) and physical function tasks (PFT) assessed at a clinic visit between 1988 and 1992, and who responded in 1992 to a mailed survey that included life satisfaction measures. Cognitive impairment was defined as ≤24 on MMSE, ≥132 on Trails B, ≤12 on Category Fluency, ≤13 on Buschke long-term recall, and ≤7 on Heaton immediate recall. Physical impairment was defined as participants' self-reported difficulty (yes/no) in performing 10 physical functions. Multiple linear regression examined associations between life satisfaction and impairment on ≥1 CFT or difficulty with ≥1 PFT. The Satisfaction with Life Scale (SWLS; range:0-26) and Life Satisfaction Index-Z (LSI-Z; range:5-35). Participants' average age was 73.4 years (range=60-94). Categorically defined cognitive impairment was present in 40% of men and 47% of women. Additionally, 30% of men and 43% of women reported difficulty performing any PFT. Adjusting for age and impairment on ≥1 CFT, difficulty performing ≥1 PFT was associated with lower LSI-Z and SWLS scores in men (β=-1.73, -1.26, respectively, p<0.05) and women (β=-1.79, -1.93, respectively, p<0.01). However, impairment on ≥ 1 CFT was not associated with LSI-Z or SWLS score after adjusting for age and difficulty with ≥1 PFT. Limited cognitive function was more common than limited physical function; however, limited physical function was more predictive of lower life satisfaction. Interventions to increase or maintain mobility among older adults may improve overall life satisfaction. Copyright © 2016. Published by Elsevier Ireland Ltd.

The purpose of this study was two-fold. The first goal was to investigate which variables were associated with the remaining physical limitations of severely injured patients after the initial rehabilitation phase. Second, we investigated whether physical limitations were attributable to the association between psychological complaints and quality of life in this patient group. Patients who were 18 years or older and who had an injury severity score (ISS)>15 completed a set of questionnaires at one time-point after their rehabilitation phase (15-53 months after their trauma). The Short Musculoskeletal Function Assessment (SMFA) questionnaire was used to determine physical limitations. The Hospital Anxiety and Depression Scale, the Dutch Impact of Event Scale and the Cognitive Failure Questionnaire were used to determine psychological complaints, and the World Health Organization Quality of Life assessment instrument-BREF was used to measure general Quality of Life (QOL). Differences in physical limitations were investigated for several trauma- and patient-related variables using non-parametric independent-sample Mann-Whitney U tests. Multiple linear regression was performed to investigate whether the decreased QOL of severely injured patients with psychological complaints could be explained by their physical limitations. Older patients, patients with physical complaints before the injury, patients with higher ISS scores, and patients who had an injury of the spine or of the lower extremities reported significantly more physical problems. Additionally, patients with a low education level, patients who were living alone, and those who were unemployed reported significantly more long-term physical problems. Severely injured patients without psychological complaints reported significantly less physical limitations than those with psychological complaints. The SMFA factor of Lower extremity dysfunction was a confounder of the association between psychological complaints and QOL in all QOL domains. Long-term physical limitations were mainly reported by patients with psychological complaints. The decreased QOL of severely injured patients with psychological complaints can partially be explained by physical limitations, particularly those involving lower extremity function. Experienced physical limitations were significantly different for some trauma and patient characteristics. These characteristics may be used to select patients for whom a rehabilitation programme would be useful. Copyright © 2017. Published by Elsevier Ltd.

Despite advances in the care of infants, there remain many newborns whose medical conditions are incompatible with sustained life. At times, healthcare providers and parents may agree that prolonging life is not an appropriate goal of care, and they may redirect treatment to alleviate suffering. While pediatric palliative treatment protocols are gaining greater acceptance, there remain some children whose suffering is unrelenting despite maximal efforts. Due to the realization that some infants suffer unbearably (ie, the burdens of suffering outweigh the benefits of life), the Dutch have developed a protocol for euthanizing these newborns. In this review, I examine the ethical aspects of 6 forms of end of life care, explain the ethical arguments in support of euthanasia, review the history and verbiage of the United States regulations governing limiting and withdrawing life-prolonging interventions in infants, describe the 3 categories of neonates for whom the Dutch provide euthanasia, review the published analyses of the Dutch protocol, and finally present some practical considerations should some form of euthanasia ever be deemed appropriate.
Physiology limits commercially viable photoautotrophic production of microalgal biofuels.
Kenny, Philip; Flynn, Kevin J
2017-01-01
Algal biofuels have been offered as an alternative to fossil fuels, based on claims that microalgae can provide a highly productive source of compounds as feedstocks for sustainable transport fuels. Life cycle analyses identify algal productivity as a critical factor affecting commercial and environmental viability. Here, we use mechanistic modelling of the biological processes driving microalgal growth to explore optimal production scenarios in an industrial setting, enabling us to quantify limits to algal biofuels potential. We demonstrate how physiological and operational trade-offs combine to restrict the potential for solar-powered algal-biodiesel production in open ponds to a ceiling of ca. 8000 L ha -1 year -1 . For industrial-scale operations, practical considerations limit production to ca. 6000 L ha -1 year -1 . According to published economic models and life cycle analyses, such production rates cannot support long-term viable commercialisation of solar-powered cultivation of natural microalgae strains exclusively as feedstock for biofuels. The commercial viability of microalgal biofuels depends critically upon limitations in microalgal physiology (primarily in rates of C-fixation); we discuss the scope for addressing this bottleneck concluding that even deployment of genetically modified microalgae with radically enhanced characteristics would leave a very significant logistical if not financial burden.

Breaking bad news should be fine-tuned to the individual patient, contain intelligible information, include emotional support and offer a tailor-made treatment plan. To achieve this goal in motor neuron disease (MND), neurologists of the amyotrophic lateral sclerosis (ALS) centre Amsterdam deliver the message on 2 separate visits within 14 days. To evaluate how patients with MND react to and view disclosure of the diagnosis, in this 2-tiered approach. Non-participating observations and in-depth interviews with patients were conducted in 1 tertiary ALS referral centre. Qualitative analysis consisted of inductive analysis of observation reports and verbatim typed out interviews. 10 2-tiered appointments were observed and 21 Dutch patients with MND interviewed. They experienced the straightforward message to be suffering from a fatal disease as devastating, yet unavoidable. The prospect of a short-term second appointment offered structure for the period immediately following the diagnosis. The time between appointments provided the opportunity for a first reorientation on their changed perspective on their life. The second appointment allowed for detailed discussions about various aspects of MND and a tailor-made treatment plan. The 2-tiered approach fits well with the way in which Dutch patients with MND process the disclosure of their diagnosis, gather information and handle the changed perspective on their life. It may serve as a model for other life-limiting diseases. Published by the BMJ Publishing Group Limited.

Life history trade-offs imposed by dragline use in two money spiders.
Bonte, Dries; Verduyn, Lieselot; Braeckman, Bart P
2016-01-01
Trade-offs among life history traits are central to understanding the limits of adaptations to stress. In animals, virtually all decisions taken during life are expected to have downstream consequences. To what degree rare, but energy-demanding, decisions carry over to individual performance is rarely studied in arthropods. We used spiders as a model system to test how single investments in silk use - for dispersal or predator escape - affect individual performance. Silk produced for safe lines and as threads for ballooning is of the strongest kind and is energetically costly, especially when resources are limited. We induced dragline spinning in two species of money spider at similar quantities to that under natural conditions and tested trade-offs with lifespan and egg sac production under unlimited prey availability and a dietary restriction treatment. We demonstrate strong trade-offs between dragline spinning and survival and fecundity. Survival trade-offs were additive to those imposed by the dietary treatment, but a reduction in eggs produced after silk use was only prevalent under conditions where food was restricted during the spider's life. Because draglines are not recycled after their use for dispersal or predator escape, their spinning incurs substantial fitness costs in dispersal, especially in environments with prey limitation. Rare but energetically costly decisions related to dispersal or predator escape may thus carry over to adult performance and explain phenotypic heterogeneity in natural populations. © 2016.

Although most seriously ill Americans wish to avoid burdensome and aggressive care at the end of life, such care is often provided unless patients or family members specifically request otherwise. Advance directives (ADs) were created to provide opportunities to set limits on aggressive care near life's end. This study tests the hypothesis that redesigning ADs such that comfort-oriented care is provided as the default, rather than requiring patients to actively choose it, will promote better patient-centred outcomes. This multicentre trial randomises seriously ill adults to receive 1 of 3 different ADs: (1) a traditional AD that requires patients to actively choose their goals of care or preferences for specific interventions (eg, feeding tube insertion) or otherwise have their care guided by their surrogates and the prevailing societal default toward aggressive care; (2) an AD that defaults to life-extending care and receipt of life-sustaining interventions, enabling patients to opt out from such care; or (3) an AD that defaults to comfort care, enabling patients to opt into life-extending care. We seek to enrol 270 patients who return complete, legally valid ADs so as to generate sufficient power to detect differences in the primary outcome of hospital-free days (days alive and not in an acute care facility). Secondary outcomes include hospital and intensive care unit admissions, costs of care, hospice usage, decision conflict and satisfaction, quality of life, concordance of preferences with care received and bereavement outcomes for surrogates of patients who die. This study has been approved by the Institutional Review Boards at all trial centres, and is guided by a data safety and monitoring board and an ethics advisory board. Study results will be disseminated using methods that describe the results in ways that key stakeholders can best understand and implement. NCT02017548; Pre-results.

Uterus transplantation: ethical and regulatory challenges.
Arora, Kavita Shah; Blake, Valarie
2014-06-01
Moving forward rapidly in the clinical research phase, uterus transplantation may be a future treatment option for women with uterine factor infertility, which accounts for three per cent of all infertility in women. This new method of treatment would allow women, who currently rely on gestational surrogacy or adoption, to gestate and birth their own genetic offspring. Since uterus transplantation carries significant risk when compared with surrogacy and adoption as well as when compared with other organ transplants, it requires greater justification because its goals are quality of life, not life-saving, in their scope. It is important to address questions regarding the physical, psychosocial and ethical risks and benefits of uterus transplantation for all three parties involved--the patient, the donor and the potential child--as well as discuss the regulatory implications as research on uterus transplantations moves forward.

The circadian clock of Neurospora crassa.
Baker, Christopher L; Loros, Jennifer J; Dunlap, Jay C
2012-01-01
Circadian clocks organize our inner physiology with respect to the external world, providing life with the ability to anticipate and thereby better prepare for major fluctuations in its environment. Circadian systems are widely represented in nearly all major branches of life, except archaebacteria, and within the eukaryotes, the filamentous fungus Neurospora crassa has served for nearly half a century as a durable model organism for uncovering the basic circadian physiology and molecular biology. Studies using Neurospora have clarified our fundamental understanding of the clock as nested positive and negative feedback loops regulated through transcriptional and post-transcriptional processes. These feedback loops are centered on a limited number of proteins that form molecular complexes, and their regulation provides a physical explanation for nearly all clock properties. This review will introduce the basics of circadian rhythms, the model filamentous fungus N. crassa, and provide an overview of the molecular components and regulation of the circadian clock. © 2011 Federation of European Microbiological Societies.

Adaptation: a contemporary view, revisiting Crichton-Miller's 1925 paper.
Music, Graham
2016-03-01
In this paper I discuss a contemporary 'take' on the concept of adaptation in light of Crichton-Miller's original 1926 paper. I look briefly at some of the ways that contemporary thinking is both similar to and different from ideas of 90 years ago. In particular I think about how recent neurobiological findings, epigenetic research and attachment theory have cast new light on our understanding of the ways humans adapt to social and emotional environments. It looks at how psychiatric presentations which are seen as maladaptive might well have an adaptive origin in early life. In this account I emphasise how a more modern version of evolutionary theory can be developed, particularly one influenced by life history theory, and suggest that such ideas have powerful explanatory power as well as being based solidly in good research.

Meaning of living with severe chronic obstructive lung disease: a qualitative study.

To explore what it means for patients to live with chronic obstructive pulmonary disease (COPD) as an incurable and constantly progressing disease. Qualitative longitudinal study using narrative and semistructured interviews. This paper presents findings of the initial interviews. Analysis using grounded theory. Lung care clinics and community care in Lower Saxony, Germany. 17 patients with advanced-stage COPD (Global Initiative for Chronic Obstructive Lung Disease (GOLD) III/IV). Analysis shows that these patients have difficulties accepting their life situation and feel at the mercy of the disease, which could be identified as a core-experienced phenomenon. Over a long period of time, patients have only a vague feeling of being ill, caused by uncertain knowledge, slow progress and doubtful attribution of clinical symptoms of the disease (causal conditions). As an action strategy, patients try to maintain daily routines for as long as possible after diagnosis. Both effective standard and rescue medication, which helps to reduce breathlessness and other symptoms, and the feeling of being faced with one's own responsibility (intervening conditions) support this strategy, whereby patients' own responsibility is too painful to acknowledge. As a consequence, patients try to deny the threat to life for a long period of time. Frequently, they need to experience facing their own limits, often in the form of an acute crisis, to realise their health situation. The experience of the illness is contextualised by a continuous increase in limited mobility and social isolation. In order to help patients to improve disease awareness, to accept their life situation and to improve their reduced quality of life, patients may benefit from the early integration of palliative care (PC), considering its multiprofessional patient-centred and team-centred approach. Psychological support and volunteer work, which are relevant aspects of PC, should be appropriate to address psychosocial needs. More research is needed to evaluate how patients could benefit from early PC. Published by the BMJ Publishing Group Limited.

This paper, pursuing themes indefatigably defended in this journal and elsewhere by Professors Jenny and Celia Kitzinger, explains what led me to write my own advance decision (AD) to refuse life-prolonging treatment if I become legally incapacitated to make my own healthcare decisions for longer than 3 months and am medically assessed as very unlikely to regain such legal capacity. I attach my Advance Decision to Refuse Life Prolonging Treatment to the online version of this paper for comment advice and possible general interest. I argue that while a Supreme Court judgement in 2013, followed by a Court of Protection judgement in 2015 greatly ameliorate my earlier concerns about excessive judicial emphasis on the sanctity of life, certain current requirements in the Code of Practice to the Mental Capacity Act 2005 and in the Rules of the Court of Protection, especially Practice Direction 9E, concerning permanent vegetative state and minimally conscious state, seem clearly to contradict aspects of that Supreme Court judgement. If the logical implications of those legal requirements were thoroughly implemented medical practice would be substantially and undesirably skewed towards provision of treatments to prolong life that are unwanted, non-beneficial and wasteful of healthcare resources. I urge that these legal requirements are modified to make them consistent with the Supreme Court's judgement in Aintree v James. Published by the BMJ Publishing Group Limited.

Couple-based communication interventions have beneficial effects for patients with cancer and their partners. However, few studies have targeted patients with advanced stages of disease and little is known about how best to assist couples in discussing issues related to life-limiting illness. The purpose of the present study was to identify themes couples addressed during a couple communication skills intervention, and the frequency with which they discussed issues related to end-of-life. Content analyses were conducted on recordings of 72 sessions from 12 couples facing advanced gastrointestinal (GI) cancer. Coding was based six themes identified a priori from the framework for understanding what patients and family value at end of life. The percent of couples addressing each theme was calculated to gauge level of importance and acceptability of these topics. The majority of couples addressed topics previously identified as salient at end-of-life, including clear decision making, affirmation of the whole person, pain and symptom management, contributing to others, and preparation for death. In addition, novel aspects to these themes emerged in the context of couples' conversations, illustrating the importance of the couple relationship in adjusting to life with a life-limiting illness and anticipating the transition to end-of-life. Findings suggest that couples likely would be receptive to an intervention that combines training in communication skills with guidance in focusing on issues related to life completion to assist with transitions at end of life. Such interventions might enhance both individuals' abilities to cope with illness-related symptoms and demands, enjoy the time they have together, and derive meaning from the experience.

This article overviews previously published and ongoing research from the Americans' Changing Lives (ACL) Study, a longitudinal study of a nationally representative sample of 3,617 adults aged 25 years and older when first interviewed in 1986, focusing on socioeconomic disparities in the way health changes with age during middle and later life, especially in terms of compression of morbidity/functional limitations. A variety of descriptive and multivariate regression and growth curve analyses are done on the ACL sample, now surveyed over four waves spanning 15.5 years between 1986 and 2001/2002 with continuing mortality ascertainment via the National Death Index, death certificate searches, and informant reports. Both cross-sectional and longitudinal analyses indicate that socioeconomic disparities in health are small in early adulthood, increase through middle and early old age, and then lessen again in later old age. In other terms, compression of morbidity/functional limitations into the later stages of the life course is realized to a much greater degree among the better educated compared with the less educated. Cross-sectional evidence suggests that this reflects differential exposure to or experience of a wide range of psychosocial, environmental, and biomedical risk factors for health (and perhaps their differential impact at different ages and life stages), as well as variations in biological robustness and frailty and also perhaps in the strength of social welfare supports for health at different life stages. Longitudinal analyses reveal several new insights: (a) The flow of causality is much greater from socioeconomic position to health than vice versa; (b) education plays a greater role relative to income in the onset of functional limitations, whereas income has much stronger effects on their progression or course; and (c) educational disparities in the onset and hence of compression of functional limitations over the life course have increased strikingly in later middle and early old age (ages 55-84 years) since 1986. The results indicate that understanding and alleviating social disparities in health are both theoretically and methodologically quintessential problems of life course analysis and research.

Dysregulated biological stress systems and adverse life events, independently and in interaction, have been hypothesised to initiate chronic pain. We examine whether (1) function of biological stress systems, (2) adverse life events, and (3) their combination predict the onset of chronic multisite musculoskeletal pain. Subjects (n=2039) of the Netherlands Study of Depression and Anxiety, free from chronic multisite musculoskeletal pain at baseline, were identified using the Chronic Pain Grade Questionnaire and followed up for the onset of chronic multisite musculoskeletal pain over 6 years. Baseline assessment of biological stress systems comprised function of the hypothalamic-pituitary-adrenal axis (1-h cortisol awakening response, evening levels, postdexamethasone levels), the immune system (basal and lipopolysaccharide-stimulated inflammation) and the autonomic nervous system (heart rate, pre-ejection period, SD of the normal-to-normal interval, respiratory sinus arrhythmia). The number of recent adverse life events was assessed at baseline using the List of Threatening Events Questionnaire. Hypothalamic-pituitary-adrenal axis, immune system and autonomic nervous system functioning was not associated with onset of chronic multisite musculoskeletal pain, either by itself or in interaction with adverse life events. Adverse life events did predict onset of chronic multisite musculoskeletal pain (HR per event=1.14, 95% CI 1.04 to 1.24, p=0.005). This longitudinal study could not confirm that dysregulated biological stress systems increase the risk of developing chronic multisite musculoskeletal pain. Adverse life events were a risk factor for the onset of chronic multisite musculoskeletal pain, suggesting that psychosocial factors play a role in triggering the development of this condition.

The increasing incidence of childhood obesity in Asia could be a reflection of early life programming in which environmental/nutritional challenges during pregnancy and first two years of life (the so-called first 1000 days) influence later health. To assess differences/similarities of anthropometric measures in early life and their influences on metabolic health risk in later life among children in Asia. Literature search for publication in English using selected key words from Medline (PubMed), Scopus, Science Direct and Google Scholar published from 1994 to October 2014. Some comparisons with Caucasian setting were made when relevant. From 152 publications selected for this narrative review, differences in foetal growth and birth weight were deducted between Asian and Caucasian children. Infants in India and Hong Kong had increased fat mass at birth and early infancy as compared to those from other parts of the world. Pre- and during pregnancy conditions influenced birth weight; feeding practices and gender influenced post-natal growth and body composition development. High and low birth weights followed by rapid postnatal growth were linked to increased risks of obesity, insulin resistance and high blood pressure in later life. Foetal and postnatal growth trajectories are different between countries within and outside Asia. Extremes in birth weight followed by rapid postnatal growth were linked to increased risks of metabolic health of children in this region. As there is limited evidence in Asia, it is important to conduct thorough investigations by using longitudinal studies on early life programming.

Despite being one of the healthiest countries in the world, Australia displays substantial mortality differentials by socioeconomic disadvantage, remoteness and sex. In this study, we examined how these mortality differentials translated to differences in life expectancy between 2001 and 2012. Population-based study using mortality and estimated residential population data from Australia's largest state, New South Wales (NSW), between 2001 and 2012. Age-group-specific death rates by socioeconomic disadvantage quintile, remoteness (major cities vs regional and remote areas), sex and year were estimated via Poisson regression, and inputted into life table calculations to estimate life expectancy. Life expectancy decreased with increasing socioeconomic disadvantage in males and females. The disparity between the most and least socioeconomically deprived quintiles was 3.77 years in males and 2.39 years in females in 2012. Differences in life expectancy by socioeconomic disadvantage were mostly stable over time. Gender gaps in life expectancy ranged from 3.50 to 4.93 years (in 2012), increased with increasing socioeconomic disadvantage and decreased by ∼1 year for all quintiles between 2001 and 2012. Overall, life expectancy varied little by remoteness, but was 1.8 years higher in major cities compared to regional/remote areas in the most socioeconomically deprived regions in 2012. Socioeconomic disadvantage and sex were strongly associated with life expectancy. The disparity in life expectancy across the socioeconomic spectrum was larger in males and was stable over time. In contrast, gender gaps reduced for all quintiles between 2001 and 2012, and a remoteness effect was evident in 2012, but only for those living in the most deprived areas.

The impact of delinquency on young adult sexual risk behaviors and sexually transmitted infections.
Aalsma, Matthew C; Tong, Yan; Wiehe, Sarah E; Tu, Wanzhu
2010-01-01
Youth in the juvenile justice system have increased sexual risk behavior and sexually transmitted infections (STI). However, research exploring the effect of self-reported delinquency on sexual risk behavior and STI is limited, and results vary depending on the populations studied. Therefore, we used nationally representative data to examine the longitudinal association between delinquent behavior, sexual risk behavior, and STI among adolescents and young adults. We used a sample of 10,828 participants from the National Longitudinal Study of Adolescent and Health. Outcomes included STI and sexual risk behavior from Wave III (17-27-year-olds). Predictors for the generalized linear regression models (stratified by gender) include race, age, education, relationship status at Wave III, and delinquent behavior groups (life-course persistent, adolescence-limited, late-onset and nondelinquency). None of the delinquency groups were associated with young adult STI. Only life-course persistent delinquency was associated consistently with sexual risk behavior (except for condom use). The adolescence-limited and late-onset groups had limited effects on sexual risk outcomes. Life-course persistent delinquency influences the expression of young adult sexual risk behavior. However, delinquent behavior does not predict STI in a population-based sample of youth. Programs and interventions that address the sexual health of youth need to consider the role of delinquency in shaping sexual risk behaviors, and future research should explore broader societal and environmental risk factors on STIs.

Using a United Kingdom (UK)-based National Health Services perspective for 2011 this study first estimated the cost-effectiveness and budget impact implications for lopinavir/ritonavir (LPV/r) vs atazanavir plus ritonavir (ATV+RTV) treatment of antiretroviral therapy (ART)-naïve patients and secondly examined the long-term health-related quality-of-life (HRQoL) and economic implications for LPV/r vs ATV+RTV treatment of ART-experienced patients. A previously published Markov model that integrates epidemiological data of human immunodeficiency virus (HIV) with predictors of coronary heart disease (CHD) was modified under a clearly specified set of assumptions to reflect viral load (VL) suppression profiles and other differences for these two regimens, applying results from the CASTLE study in ART-naïve patients and using data from BMS-045 in ART-experienced patients. ART costs were referenced to current (2011) pricing guidelines in the UK. Medical care costs reflected UK treatment patterns and relevant drug pricing. Costs and outcomes were discounted at 3.5% per year. Costs are expressed in British pounds (£) and life expectancy in quality-adjusted life years (QALYs). In the ART-naïve subjects, the model predicted a marginal improved life expectancy of 0.031 QALYs (11 days) for the ATV+RTV regimen as a result of predicted CHD outcomes based on lower increases in cholesterol levels compared with the LPV/r regimen. The model demonstrated cost savings with the LPV/r regimen. The total lifetime cost savings was £4070 per patient for the LPV/r regimen. LPV/r saved £2133 and £3409 per patient at 5 and 10 years, respectively. Referenced to LPV/r, the incremental cost-effectiveness ratio (ICER) for ATV+RTV was £149,270/QALY. For ART-experienced patients VL suppression differences favored LPV/r, while CHD risk associated with elevated total cholesterol marginally favored ATV+RTV, resulting in a net improvement in life expectancy of 0.31 QALYs (106 days) for LPV/r. Five-year costs were £5538 per patient greater for ATV+RTV, with a discounted lifetime saving of £1445 per LPV/r patient. LPV/r was modestly dominant economically, producing better outcomes and cost savings. The limitations of this study include uncertainty related to how well the model's assumptions capture current practice, as well as the validity of the model parameters used. This study was limited to using aggregated data in the public domain from the two clinical trials. Thus, some of the model parameters may reflect limitations due to trial design and data aggregation bias. This study has attempted to illuminate the effect of these limitations by presenting the results of the comprehensive sensitivity analysis. Based on 2011 costs of HIV in the UK and the published efficacy data from the CASTLE and BMS-045 studies, ATV+RTV-based regimens are not expected to be a cost-effective use of resources for ART-naïve patients similar to patients in the CASTLE study, nor for ART-experienced patients based on the only published comparison of ATV+RTV and LPV/r.

Palliative sedation is a highly debated medical practice, particularly regarding its proper use in end-of-life care. Worldwide, guidelines are used to standardise care and regulate this practice. In this review, we identify and compare national/regional clinical practice guidelines on palliative sedation against the European Association for Palliative Care (EAPC) palliative sedation Framework and assess the developmental quality of these guidelines using the Appraisal Guideline Research and Evaluation (AGREE II) instrument. Using the PRISMA criteria, we searched multiple databases (PubMed, CancerLit, CINAHL, Cochrane Library, NHS Evidence and Google Scholar) for relevant guidelines, and selected those written in English, Dutch and Italian; published between January 2000 and March 2016. Of 264 hits, 13 guidelines-Belgium, Canada (3), Ireland, Italy, Japan, the Netherlands, Norway, Spain, Europe, and USA (2) were selected. 8 contained at least 9/10 recommendations published in the EAPC Framework; 9 recommended 'pre-emptive discussion of the potential role of sedation in end-of-life care'; 9 recommended 'nutrition/hydration while performing sedation' and 8 acknowledged the need to 'care for the medical team'. There were striking differences in terminologies used and in life expectancy preceding the practice. Selected guidelines were conceptually similar, comparing closely to the EAPC Framework recommendations, albeit with notable variations. Based on AGREE II, 3 guidelines achieved top scores and could therefore be recommended for use in this context. Also, domains 'scope and purpose' and 'editorial independence' ranked highest and lowest, respectively-underscoring the importance of good reportage at the developmental stage.

[Diabetes mellitus and depressive disorder, an undesirable association].
Nicolau, Joana; Masmiquel, Lluís
2013-12-01
Type 2 diabetes and depressive disorder are 2 chronic diseases highly prevalent in developed countries and with a negative impact on quality of life and life expectancy. In recent years, both conditions have been shown to be strongly associated. Thus, diabetics have an increased risk of suffering depressive disorder, as well as impaired glucose homeostasis, if they experience depression. In diabetic patients, concurrent depression is associated to greater difficulties in disease management and metabolic control, increased risk of developing chronic complications, decreased quality of life, and higher healthcare expenses. As a result, the interest of diabetic scientific societies in this association has increased, and they recommend regular mood assessment in diabetic patients. However, the limited clinical experience available and the conflicting results reported to date make it difficult to draw conclusions. Copyright © 2012 SEEN. Published by Elsevier Espana.

Active management of food allergy: an emerging concept.
Anagnostou, Katherine; Stiefel, Gary; Brough, Helen; du Toit, George; Lack, Gideon; Fox, Adam T
2015-04-01
IgE-mediated food allergies are common and currently there is no cure. Traditionally, management has relied upon patient education, food avoidance and the provision of an emergency medication plan. Despite this, food allergy can significantly impact on quality of life. Therefore, in recent years, evolving research has explored alternative management strategies. A more active approach to management is being adopted, which includes early introduction of potentially allergenic foods, anticipatory testing, active monitoring, desensitisation to food allergens and active risk management. This review will discuss these areas in turn. Published by the BMJ Publishing Group Limited.

Fifteen-minute consultation: public health for paediatricians-adolescent public health.
Hargreaves, Dougal S; Williams, Bhanu; Straw, Fiona; Gregorowski, Anna; Yassaee, Arrash; Devakumar, Delan
2016-10-01
Paediatricians have a key role to play in ensuring a holistic, integrated approach is taken to meeting adolescent health needs. There is increasing evidence that failure to do so can lead to poor healthcare experience, avoidable ill health and increased need for healthcare services, both in the short term and in adult life. This article aims to guide paediatricians in answering the questions 'How well are the public health and clinical needs of the adolescent population in my area being met? And how can we improve?'

The pearl of the 'Pro-Life' movement? Reflections on the Kermit Gosnell controversy.
Greasley, Kate
2014-06-01
The paper comments briefly on the recent controversy surrounding the criminal prosecution and conviction of rogue abortion doctor Kermit Gosnell in the USA, for, among other things, the murder of infants born alive. Without contesting the disturbing nature of the crimes committed by Gosnell and his colleagues, it critiques a few ways in which opponents of abortion have sought to use the case as ammunition against the legal provision of abortion and against the morality of all abortion.

Best interests decision-making and end-of-life care for patients in permanent vegetative or minimally conscious states (VS/MCS) is a complex area of clinical and legal practice, which is poorly understood by most clinicians, lawyers and members of the public. In recent weeks, the Oxford Shrieval lecture by Mr Justice Baker ('A Matter of Life and Death', 11 October 2016) and its subsequent reporting in the public press has sparked debate on the respective roles of clinicians, the Court of Protection and the Mental Capacity Act 2005 in decisions to withhold or withdraw life-sustaining treatments from patients with disorders of consciousness. The debate became polarised and confused by misquotation and inaccurate terminology, and highlighted a lack of knowledge about how patients in VS/MCS die in the absence of court approval. This article sets out the background and discussion and attempts to give a more accurate representation of the facts. In the spirit of transparency, I present a mortality review of all the patients in VS/MCS who have died under the care of my own unit in the last decade-with or without referral to the court, but always in accordance with the law. These data demonstrate that clinicians regularly undertake best interests decision-making in conjunction with families that may include life and death decisions (sometimes even the withdrawal or withholding of clinically assisted nutrition and hydration); and that these can be made within the current legal framework without necessarily involving the court in all cases. This is the first published case series of its kind. Published by the BMJ Publishing Group Limited.

For a patient nearing the end of his or her life, transfer from a nursing home to the ED can be inappropriate, with potentially negative consequences, but transfer in these circumstances is, regrettably, all too common. There is a lack of published literature exploring how paramedics make decisions in end-of-life care situations. This study aims to explore how paramedics make decisions when asked to transport nursing home residents nearing the end of their lives. Phenomenological influenced design with a pragmatic approach. Semi-structured face-to-face interviews were conducted with six paramedics in an English NHS Ambulance Trust and subsequent data collected by text message. Audio-recorded interviews were transcribed verbatim and analysed using a thematic approach. Three themes emerged in relation to the decision to transport patients from nursing homes to EDs in end-of-life care situations. Paramedics identified difficulties in understanding nursing home residents' wishes. When a patient no longer had the capacity for decision making, paramedics' reasoning processes were aligned to best interest decision making, weighing the risks and benefits of hospitalisation. Paramedics found it challenging to balance patients' best interests with pressure from others: nursing staff, patients' relatives and colleagues. A range of factors influence paramedics' decisions to transport nursing home residents to EDs in end-of-life care situations. Decision making became a process of negotiation when the patient's perceived best interests conflicted with that of others, resulting in contrasting approaches by paramedics. This paper considers how paramedics might be better trained and supported in dealing with these situations, with the aim of providing dignified and appropriate care to patients as they reach the end of their lives.

Using social media in supportive and palliative care research.
Casañas i Comabella, Carolina; Wanat, Marta
2015-06-01
Difficulties relating to supportive and palliative care research are often reported. However, studies have highlighted that people near the end of life are happy to participate in research and want their voices heard. Thus, one may raise a twofold question: are we limiting the free will of people who are seriously ill? And are we missing important data, which probably cannot be obtained from other sources? In light of this landscape, a new opportunity has emerged: the use of social media (SM). This paper provides a comprehensive summary of SM, including its theoretical underpinnings, and recent examples of successful uses of SM in healthcare research. It also outlines the opportunities (wider reach, direct access, the potential of Big Data, readiness of research data, empowered participants) and challenges (anonymity of participants, digital divide, sample bias, screening and 'saying no' to participants, data analysis) of using SM in end-of-life care research. Finally, it describes the practical steps that a researcher could follow to recruit patients using SM. Implications for palliative care clinicians, researchers and policymakers are also discussed, with a focus on the need to facilitate patient-centred care through the use of SM. The need for relevant and updated guidelines in this new, emerging field is highlighted. Published by the BMJ Publishing Group Limited.

The successful operation of long-life, highly loaded mechanisms used for planetary exploration or autonomous structures assembly will depend upon the ability to effectively lubricate rolling-element bearings. As new tools are developed (i.e., drill, abraders, robotic manipulators, etc.) that interact with their environment in a more direct manner, lubricants will be pushed past the bounds that current scientific literature has published. This paper details results from bearing lubrication lifetime testing performed in support of Honeybee Robotics development of the Mars Science Laboratory (MSL) Surface Removal Tool (SRT). This testing was done due to the lack of available data in research literature that is applicable to the lubrication regime the SRT bearings are being designed for. Based on the test results, the chosen bearing arrangement can be used for the SRT Grind Shaft bearings with the use of a Braycote Micronic 601EF grease-plate with a 10 vol% grease slurry fill (50/50 wt% Braycote Micronic 601EF and Brayco 815Z). This arrangement showed no signs of detrimental degradation over the course of the 3x life test. The purely grease-plated bearing ran at a consistently higher torque and showed signs of failure beginning at approximately 2.2 x 10(exp 7) revs (approximately 6.3 x 10(exp 7) stress-cycles) with a torque over-limit failure at approximately 4.5 x 10(exp 7) revs (approximately 1.3 x 10(exp 8) stress-cycles). Barring cold-start torque margin limitations, it is recommended that any long-life bearing application include some vol% grease-pack in addition to a standard grease-plate to reduce parasitic torque and increase bearing life. While these results are specific to a particular environment and loading condition, they demonstrate the extended capabilities of a commonly used flight lubricant outside of the range that is published in current research literature.

More adolescents report pain now than previously. In Norway, episodic pain problems have been reported by 60% of children and adolescents aged 8-18 years, with 21% reporting duration of pain of more than 3 months. Since adolescents spend much time at school, the attitude and behaviour of teachers play important roles regarding the experience of pain felt by adolescents in everyday life. Yet research on how teachers perceive the pain experienced by adolescents in a school setting is limited. We therefore seek to gain insight to teachers' classroom experiences with (1) adolescent's self-reported pain symptoms; (2) adolescents management of their pain and (3) how to help adolescents manage their pain. Teachers in 5 junior high schools in Norway representing municipalities in 3 rural areas and 2 cities. A qualitative study with an explorative design comprising 5 focus group interviews. Each group consisted of 3-8 junior high school teachers. A semistructured interview guide was used to cover the issues. The transcribed text was analysed with qualitative content analysis. 22 teachers participated (5 men, 17 women; age range 29-62 years) with teaching experience ranging from 3 to nearly 40 years. The main theme describing the experience of teachers with adolescents' pain in everyday life is that pain and management of pain is a social, physical and psychological interwoven phenomenon. Through empirical analyses, 3 subcategories emerged: (1) everyday pain--expressing strenuous life; (2) managing pain--escaping struggle and (3) strategies of teachers--support and normalisation. Teachers have a biopsychosocial understanding and approach to pain experienced by adolescents. This understanding influences the role of teachers as significant others in the lives of adolescents with regard to pain and management of their pain in a school setting.

Longitudinal studies on the evolution of autism spectrum disorder (ASD) symptoms are limited and have primarily used repeated measurements performed several months apart. However, measurements of changes in everyday life should more closely reflect the 'real life' of the patient and his or her family. We propose to study the child's ASD symptoms and their effect on the quality of life, psychological status and anxiety of the child's parents over a 6-month period using SMARTAUTISM, a smartphone application. This is a prospective, longitudinal, exploratory, open study with a 6-month follow-up period. Data will be recorded longitudinally over multiple weeks under natural conditions. The factors affecting the quality of life and anxiety of parents of children with ASD and the children's functional symptoms will be examined, and the feasibility of using a smartphone application designed for parents of ASD patients will be assessed. Explore the evolution of a child's behaviour over 6 months and the (psychological and social) effects of these changes on the family. Assess the feasibility of our application by examining the filling rate and application usage by parents for 6 months. 100 families containing 1 child diagnosed with ASD will be included. At baseline, sociodemographic, psychiatric and medical data will be recorded. The correlations of the general epidemiological variables (primary outcome measure) will be evaluated via multivariate analysis. The application filling rate (relative to the ideal filling rate) will be used to assess the feasibility of the application (secondary outcome measure). The SMARTAUTISM study has the approval of the local ethics committee, and data security will be ensured via the use of encryption and a secure medical server. The use of this application will be proposed at autism resource centres across France. Published by the BMJ Publishing Group Limited.

Inspiratory muscle training to enhance recovery from mechanical ventilation: a randomised trial.
Bissett, Bernie M; Leditschke, I Anne; Neeman, Teresa; Boots, Robert; Paratz, Jennifer
2016-09-01
In patients who have been mechanically ventilated, inspiratory muscles remain weak and fatigable following ventilatory weaning, which may contribute to dyspnoea and limited functional recovery. Inspiratory muscle training may improve inspiratory muscle strength and endurance following weaning, potentially improving dyspnoea and quality of life in this patient group. We conducted a randomised trial with assessor-blinding and intention-to-treat analysis. Following 48 hours of successful weaning, 70 participants (mechanically ventilated ≥7 days) were randomised to receive inspiratory muscle training once daily 5 days/week for 2 weeks in addition to usual care, or usual care (control). Primary endpoints were inspiratory muscle strength and fatigue resistance index (FRI) 2 weeks following enrolment. Secondary endpoints included dyspnoea, physical function and quality of life, post-intensive care length of stay and in-hospital mortality. 34 participants were randomly allocated to the training group and 36 to control. The training group demonstrated greater improvements in inspiratory strength (training: 17%, control: 6%, mean difference: 11%, p=0.02). There were no statistically significant differences in FRI (0.03 vs 0.02, p=0.81), physical function (0.25 vs 0.25, p=0.97) or dyspnoea (-0.5 vs 0.2, p=0.22). Improvement in quality of life was greater in the training group (14% vs 2%, mean difference 12%, p=0.03). In-hospital mortality was higher in the training group (4 vs 0, 12% vs 0%, p=0.051). Inspiratory muscle training following successful weaning increases inspiratory muscle strength and quality of life, but we cannot confidently rule out an associated increased risk of in-hospital mortality.

There is limited evidence documenting the effectiveness of Advance Care Planning (ACP) in cancer care. The present randomised trial is designed to evaluate whether the administration of formal ACP improves compliance with patients' end-of-life (EOL) wishes and patient and family satisfaction with care. A randomised control trial in eight oncology centres across New South Wales and Victoria, Australia, is designed to assess the efficacy of a formal ACP intervention for patients with cancer. Patients with incurable cancer and an expected survival of 3-12 months, plus a nominated family member or friend will be randomised to receive either standard care or standard care plus a formal ACP intervention. The project sample size is 210 patient-family/friend dyads. The primary outcome measure is family/friend-reported: (1) discussion with the patient about their EOL wishes and (2) perception that the patient's EOL wishes were met. Secondary outcome measures include: documentation of and compliance with patient preferences for medical intervention at the EOL; the family/friend's perception of the quality of the patient's EOL care; the impact of death on surviving family; patient-family and patient-healthcare provider communication about EOL care; patient and family/friend satisfaction with care; quality of life of patient and family/friend subsequent to trial entry, the patient's strength of preferences for quality of life and length of life; the costs of care subsequent to trial entry and place of death. Ethical approval was received from the Sydney Local Health District (RPA Zone) Human Research Ethical Committee, Australia (Protocol number X13-0064). Study results will be submitted for publication in peer-reviewed journals and presented at national and international conferences. Pre-results; ACTRN12613001288718.

Limited data exist on health-related quality of life (HRQoL) after intracerebral haemorrhage (ICH). We aimed to determine baseline factors associated with HRQoL among participants of the pilot and main phases of the Intensive Blood Pressure Reduction in Acute Cerebral Haemorrhage Trials (INTERACT 1 and 2). The INTERACT studies were randomised controlled trials of early intensive blood pressure (BP) lowering in patients with ICH (<6 hours) and elevated systolic BP (150-220 mm Hg). HRQoL was determined using the European Quality of Life Scale (EQ-5D) at 90 days, completed by patients or proxy responders. Binary logistic regression analyses were performed to identify factors associated with poor overall HRQoL. 2756 patients were included. Demographic, clinical and radiological factors associated with lower EQ-5D utility score were age, randomisation outside of China, antithrombotic use, high baseline National Institutes of Health Stroke Scale (NIHSS) score, larger ICH, presence of intraventricular extension and use of proxy responders. High (≥14) NIHSS score, larger ICH and proxy responders were associated with low scores in all five dimensions of the EQ-5D. The NIHSS score had a strong association with poor HRQoL (p<0.001). Female gender and antithrombotic use were associated with decreased scores in dimensions of pain/discomfort and usual activity, respectively. Poor HRQoL was associated with age, comorbidities, proxy source of assessment, clinical severity and ICH characteristics. The strongest association was with initial clinical severity defined by high NIHSS score. NCT00226096 and NCT00716079; Post-results. Published by the BMJ Publishing Group Limited.

OA11 Public health and hospices: what is really possible?
Hartley, Nigel; Richardson, Heather
2015-04-01
Whilst a growing number of hospices are proactively engaging in the public health agenda, questions remain about whether this is an approach that hospices can adopt successfully. (Sallnow et al . 2014). The experience of St Christopher's in the development of its social hub (The Anniversary Centre) offers insights into the challenges and how these are best addressed. The Anniversary Centre was established to provide a more open and flexible approach to end of life care and to challenge and change public attitudes towards death and dying. It sought, also, to contest an existing culture of care, shifting from professional management of problems to one in which people take a lead in their own care and wellbeing. A review of the progress of the Centre in achieving these aims has been undertaken five years after its establishment. Questions focus on: The degree to which the centre has engaged more of the local communities How much its users are able to determine their own priorities, care and wellbeing through attendance at the centre What evidence of a public health approach exists in the support it provides. The Centre offers a new and alternative way of supporting people living with a life threatening condition. Although successes have been achieved, organisational and historical cultural barriers continue to limit progress. Hospice culture can prohibit public health approaches to palliative care. However, related innovation is possible when clear values and stories are shared, champions are identified and professional assumptions are challenged. Sallnow L, Paul S.

Since our knowledge of the associations between socioeconomic position (SEP) over the life course and inflammatory and metabolic markers, which are excellent predictors of cardiovascular disease, remains limited, we examined the association between social mobility over the life course and these markers at older ages. Our study used cross-sectionally collected data from 6142 participants aged 50 years and older from the English Longitudinal Study of Ageing. We estimated linear and logistic models of the associations between social mobility, using information on childhood and adult SEP, C reactive protein (CRP), fibrinogen, glycated haemoglobin (HbA1c) and high-density lipoprotein (HDL) cholesterol. Our models were gradually adjusted for age, sex, chronic diseases, obesity, physical activity, alcohol consumption, smoking status and depressive symptoms. Participants who experienced upward social mobility had higher CRP, fibrinogen and HbA1c levels compared with those who had stable high SEP over the life course, but lower compared with those who experienced downward social mobility or had stable low SEP. They also had lower HDL levels compared with those who had stable high SEP or downwardly mobile. Adjustment for covariates partially explained the associations between social mobility and CRP and HDL, and fully explained those between social mobility and fibrinogen and HbA1c. Social mobility is associated with inflammatory and metabolic markers at older ages with some of the observed associations persisting after accounting for covariates. Upward social mobility appears to partially reverse the damaging effect of childhood social disadvantage on inflammatory profiles in older ages. Published by the BMJ Publishing Group Limited.

Futile treatment, which by definition cannot benefit a patient, is undesirable. This research investigated why doctors believe that treatment that they consider to be futile is sometimes provided at the end of a patient's life. Semistructured in-depth interviews. Three large tertiary public hospitals in Brisbane, Australia. 96 doctors from emergency, intensive care, palliative care, oncology, renal medicine, internal medicine, respiratory medicine, surgery, cardiology, geriatric medicine and medical administration departments. Participants were recruited using purposive maximum variation sampling. Doctors attributed the provision of futile treatment to a wide range of inter-related factors. One was the characteristics of treating doctors, including their orientation towards curative treatment, discomfort or inexperience with death and dying, concerns about legal risk and poor communication skills. Second, the attributes of the patient and family, including their requests or demands for further treatment, prognostic uncertainty and lack of information about patient wishes. Third, there were hospital factors including a high degree of specialisation, the availability of routine tests and interventions, and organisational barriers to diverting a patient from a curative to a palliative pathway. Doctors nominated family or patient request and doctors being locked into a curative role as the main reasons for futile care. Doctors believe that a range of factors contribute to the provision of futile treatment. A combination of strategies is necessary to reduce futile treatment, including better training for doctors who treat patients at the end of life, educating the community about the limits of medicine and the need to plan for death and dying, and structural reform at the hospital level.

A large body of evidence documents the adverse relationship between concentrated deprivation and health. Among the evaluations of regeneration initiatives to tackle these spatial inequalities, few have traced the trajectories of individuals over time and fewer still have employed counterfactual comparison. We investigate the impact of one such initiative in England, the New Deal for Communities (NDC), which ran from 1999 to 2011, on socioeconomic inequalities in health trajectories. Latent Growth Curve modelling of within-person changes in self-rated health, mental health and life satisfaction between 2002 and 2008 of an analytical cohort of residents of 39 disadvantaged areas of England in which the NDC was implemented, compared with residents of comparator, non-intervention areas, focusing on: (1) whether differences over time in outcomes can be detected between NDC and comparator areas and (2) whether interventions may have altered socioeconomic differences in outcomes. No evidence was found for an overall improvement in the three outcomes, or for significant differences in changes in health between respondents in NDC versus comparator areas. However, we found a weakly significant gap in life satisfaction and mental health between high and low socioeconomic status individuals in comparator areas which widened over time to a greater extent than in NDC areas. Change over time in the three outcomes was non-linear: individual improvements among NDC residents were largest before 2006. There is limited evidence that the NDC moderated the impact of socioeconomic factors on mental health and life satisfaction trajectories. Furthermore, any NDC impact was strongest in the first 6 years of the programmes. Published by the BMJ Publishing Group Limited.

2016-06-01
Information and communication technology (ICT) is potentially mature enough to empower outdoor and social activities in dementia. However, actual ICT-based devices have limited functionality and impact, mainly limited to safety. What is an ideal operational framework to enhance this field to support outdoor and social activities? Review of literature and cross-disciplinary expert discussion. A situation-aware ICT requires a flexible fine-tuning by stakeholders of system usability and complexity of function, and of user safety and autonomy. It should operate by artificial intelligence/machine learning and should reflect harmonized stakeholder values, social context, and user residual cognitive functions. ICT services should be proposed at the prodromal stage of dementia and should be carefully validated within the life space of users in terms of quality of life, social activities, and costs. The operational framework has the potential to produce ICT and services with high clinical impact but requires substantial investment. Copyright © 2016 The Authors. Published by Elsevier Inc.

Willingness to pay per quality-adjusted life year for life-saving treatments in Thailand.
Nimdet, Khachapon; Ngorsuraches, Surachat
2015-10-05
To estimate the willingness to pay (WTP) per quality-adjusted life year (QALY) value for life-saving treatments and to determine factors affecting the WTP per QALY value. A cross-sectional survey with multistage sampling and face-to-face interviews. General population in the southern part of Thailand. A total of 600 individuals were included in the study. Only 554 (92.3%) responses were usable for data analyses. Participants were asked for the maximum amount of WTP value for life-saving treatments by an open-ended question. EQ-5D-3L and visual analogue scale (VAS) were used to estimate additional QALY. The amount of WTP values varied from 0 to 720,000 Baht/year (approximately 32 Baht=US$1). The averages of additional QALY obtained from VAS and EQ-5D-3L were only slightly different (0.872 and 0.853, respectively). The averages of WTP per QALY obtained from VAS and EQ-5D-3L were 244,720 and 243,120 Baht/QALY, respectively. As compared to male participants, female participants were more likely to pay less for an additional QALY (p=0.007). In addition, participants with higher household incomes tended to have higher WTP per QALY values (p<0.001). Our study added another WTP per QALY value specifically for life-saving treatments, which would complement the current cost-effectiveness threshold used in Thailand and optimise patient access to innovative treatments or technologies.

Studying patients during the end of life is important, as it has the potential to lead to improvements in care for the dying. For patients who die after a controlled withdrawal of life-sustaining therapies in the intensive care unit, information about the natural history of death and the process of removing life support has additionally led to advances in practice for deceased organ donation. However, this unique population of severely critically ill and imminently dying patients has been difficult to study, largely due to assumptions made by research teams and ethics boards alike about the logistical difficulties of obtaining consent and completing research procedures before or during the process of withdrawal of life-sustaining therapies. In this paper, we describe the ethics substudy of the first prospective observational research study in Canada to obtain consent and collect clinical data on patients during the process of withdrawal of life-sustaining therapies in the intensive care unit. We describe in detail the process of protocol development, review by five institutional research ethics boards and bedside staff satisfaction with the study. We conclude that prospective research on a critically ill and imminently dying population is feasible and can be conducted in an ethical manner. Further information is needed about the experiences and motivations of families and substitute decision makers who provide consent for research on critically ill intensive care unit patients at the end of life.

Surgical, ethical, and psychosocial considerations in human head transplantation.
Furr, Allen; Hardy, Mark A; Barret, Juan P; Barker, John H
2017-05-01
Transplanting a head and brain is perhaps the final frontier of organ transplantation. The goal of body-to-head transplantation (BHT) is to sustain the life of individuals who suffer from terminal disease, but whose head and brain are healthy. Ideally BHT could provide a lifesaving treatment for several conditions where none currently exists. BHT is no ordinary experiment, to transfer a head to another body involves extraordinarily complex medical challenges as well as ethical and existential dilemmas that were previously confined to the imagination of writers of fiction. The possibility of replacing an incurably ill body with a healthy one tests not only our surgical limits, but also the social and psychological boundaries of physical life and alters what we recognize life to be. The purpose of this target article, the complementary manuscript focused on immunological issues in BHT, and the accompanying Commentaries by scholars and practitioners in medicine, immunology, and bioethics is to review major surgical and psychosocial-ethical and immunological considerations surrounding body-to-head transplantation. We hope that together these ideas will provide readers with a comprehensive overview of the possibilities and challenges associated with BHT and initiate professional discussion and debate through which this new frontier in medicine is considered and approached.

Teaching authorship and publication practices in the biomedical and life sciences.
Macrina, Francis L
2011-06-01
Examination of a limited number of publisher's Instructions for Authors, guidelines from two scientific societies, and the widely accepted policy document of the International Committee of Medical Journal Editors (ICMJE) provided useful information on authorship practices. Three of five journals examined (Nature, Science, and the Proceedings of the National Academy of Sciences) publish papers across a variety of disciplines. One is broadly focused on topics in medical research (New England Journal of Medicine) and one publishes research reports in a single discipline (Journal of Bacteriology). Similar elements of publication policy and accepted practices were found across the policies of these journals articulated in their Instructions for Authors. A number of these same elements were found in the professional society guidelines of the Society for Neuroscience and the American Chemical Society, as well as the ICMJE Uniform Requirements for Manuscripts Submitted to Biomedical Journals. Taken together, these sources provide the basis for articulating best practices in authorship in scientific research. Emerging from this material is a definition of authorship, as well as policy statements on duplicative publication, conflict of interest disclosure, electronic access, data sharing, digital image integrity, and research requiring subjects' protection, including prior registration of clinical trials. These common elements provide a foundation for teaching about scientific authorship and publication practices across biomedical and life sciences disciplines.

To examine whether adiposity is associated with an impaired quality of life (an individual's perception of their life) in general population samples in early adolescence. Relationships between a direct measure of adiposity (fat mass index from bioimpedance) and a proxy measure (waist circumference), and a generic (KIDSCREEN-27) and a weight-specific measure of health-related quality of life (HRQoL, Impact of Weight on Quality of Life-Kids (IWQOL-Kids)) were examined in a longitudinal population-based cohort of young adolescents aged 12 years (n=519). The effects of change in adiposity over time (from 7 years and 9 years) were also examined (n=331-445 in longitudinal analyses). Impairment in HRQoL was associated with current adiposity but it was not predicted by earlier adiposity. At 12 years, higher adiposity was associated with lower Physical Well-Being on KIDSCREEN-27, and with lower Total Scores on the weight-specific IWQOL-Kids instrument, the latter particularly in girls. Health and education professionals need to be aware in their clinical practice that higher adiposity impairs HRQoL in general populations of young adolescents. Further research would be useful to determine whether or not children of primary school age self-reporting lower HRQoL are more likely to develop higher adiposity later in adolescence or early adulthood.

The objective of this study was to compare patients with epiphora and cataract in terms of the activity limitations they experience in daily life due to their visual disability and to validate the use of the Catquest-9SF questionnaire for epiphora patients. Seventy-two consecutively encountered adult patients with confirmed lacrimal obstruction and listed for dacryocystorhinostomy (DCR) or lacrimal intubation at the St. Erik Eye Hospital, Stockholm, Sweden, completed the Catquest-9SF questionnaire, which measures activity limitations in daily life due to visual disability. The psychometric qualities of the Catquest-9SF results obtained from this group of patients were evaluated by Rasch analysis. Rasch analysis was further employed to convert the ordinal raw data to a Rasch score for comparison with the preoperative scores of patients registered in the Swedish National Cataract Register (NCR) during March 2013. The Catquest-9SF exhibited good psychometric qualities when investigating epiphora patients, with the exception of a misfit for Item 4, the item regarding facial recognition. On the Rasch scale (-5.43 = no activity limitations to +5.01 = severe activity limitations), the mean score for epiphora patients was -0.82 while for patients listed for 1st eye and 2nd eye cataract surgery it was -0.17 and -0.76, respectively. An equivalence test confirmed that the reported visual disability of epiphora patients was not significantly different from visual disability reported by patients waiting for 2nd eye cataract surgery. The Catquest-9SF is a valid measure of visual disability in patients with epiphora. Epiphora patients experience visual disability to the same degree as patients awaiting 2nd eye cataract surgery. © 2017 Acta Ophthalmologica Scandinavica Foundation.

Research has shown that individual socio-economic circumstances throughout life affect health in older ages. However, little attention has been paid to the broad economic context affecting individual's life-chances. This paper examines whether economic downturns experienced during young and mid-adulthood have long-run effects on physical health. We exploit data on economic fluctuations in the period 1945-2010 in 11 European countries, linked to longitudinal data from three waves of the Survey of Health, Ageing and Retirement in Europe. We estimate a country fixed effect model assessing whether downturns experienced at 5-year intervals between ages 25 and 54 are associated with levels and onset of new limitations with Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) in older age (55-80). Experiencing an economic downturn at ages 45-59 is associated with increased risk of having at least one disability limitation in later-life (odds ratio [OR] for ADL = 1.66, 95% CI [Confidence Interval] 1.24, 2.22; OR for IADL = 1.46, 95% CI 1.10, 1.94). Economic downturns at ages 40-44 and 45-49 also increase the risk of a new functional limitation in later-life (OR for IADL ages 40-44 = 1.20, 95% CI 1.03, 1.40; OR for IADL ages 45-49 = 1.44, CI 1.10-1.88). Economic downturns experienced around these ages are also associated with significantly greater risks of smoking and excessive alcohol consumption as well as lower incomes in older age. Exposure to an economic downturn at ages 40-49 is associated with poorer health in older ages, possibly by increasing risk of unhealthy behaviours and low incomes persisting into older age. © The Author 2016.

Are end-of-life practices in Norway in line with ethics and law?
Førde, R; Aasland, O G
2014-10-01
End-of-life decisions, including limitation of life prolonging treatment, may be emotionally, ethically and legally challenging. Euthanasia and physician-assisted suicide (PAS) are illegal in Norway. A study from 2000 indicated that these practices occur infrequently in Norway. In 2012, a postal questionnaire addressing experience with limitation of life-prolonging treatment for non-medical reasons was sent to a representative sample of 1792 members of the Norwegian Medical Association (7.7% of the total active doctor population of 22,500). The recipients were also asked whether they, during the last 12 months, had participated in euthanasia, PAS or the hastening of death of non-competent patients. Seventy-one per cent of the doctors responded. Forty-four per cent of the respondents reported that they had terminated treatment at the family's request not knowing the patient's own wish, doctors below 50 and anaesthesiologists more often. Anaesthesiologists more often reported to have terminated life-prolonging treatment because of resource considerations. Six doctors reported having hastened the death of a patient the last 12 months, one by euthanasia, one by PAS and four had hastened death without patient request. Male doctors and doctors below 50 more frequently reported having hastened the death of a patient. Forgoing life-prolonging treatment at the request of the family may be more frequent in Norway that the law permits. A very small minority of doctors has hastened the death of a patient, and most cases involved non-competent patients. Male doctors below 50 seem to have a more liberal end-of-life practice. © 2014 The Acta Anaesthesiologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.
Parents and end-of-life decision-making for their child: roles and responsibilities.
Sullivan, Jane; Gillam, Lynn; Monagle, Paul
2015-09-01
Whether parents want to be and should be the decision-maker for their child in end-of-life matters are contested clinical and ethical questions. Previous research outcomes are equivocal. A qualitative interview method was used to examine the views and experiences of 25 bereaved parents in end-of-life decision-making for their child. Data were analysed thematically. Three types of decision-making roles were identified: self-determined, guided (both involving active decision-making) and acquiescent (passive).The majority of parents had been active in the decision-making process for their child. They perceived themselves as the ultimate end-of-life decision-maker. This was perceived as part of their parental responsibility. A minority of parents did not consider that they had been an active, ultimate decision-maker. Generally, parents in the self-determined and guided groups reported no negative consequences from their decision-making involvement. Importantly, parents in the acquiescent group described their experience as difficult at the time and subsequently, although not all difficulties related directly to decision-making. Parents considered that in principle parents should be the end-of-life decision-maker for their child, but understood personal characteristics and preference could prevent some parents from taking this role. This study unequivocally supports parents' desire to fulfil the end-of-life decision-making role. It provides a nuanced understanding of parents' roles and contributes evidence for the ethical position that parents should be the end-of-life decision-makers for their child, unless not in the child's best interests. On the whole, parents want this role and can manage its consequences. Indeed, not being the end-of-life decision-maker could be detrimental to parents' well-being.

Disseminated intravascular coagulation in paediatrics.
Rajagopal, Revathi; Thachil, Jecko; Monagle, Paul
2017-02-01
Disseminated intravascular coagulation (DIC) in paediatrics is associated with significant morbidity and mortality. Although there have been several recent advances in the pathophysiology of DIC, most of these studies were done in adults. Since the haemostatic system is very different in early life and changes dramatically with age, creating a variety of challenges for the clinician, delay in the diagnosis of DIC can happen until overt DIC is evident. In this review article, we report the aetiology, pathophysiology, clinical manifestations, diagnostic tests and a management algorithm to guide paediatricians when treating patients with DIC.

Future care planning: a first step to palliative care for all patients with advanced heart disease.
Denvir, M A; Murray, S A; Boyd, K J
2015-07-01
Palliative care is recommended for patients with end-stage heart failure with several recent, randomised trials showing improvements in symptoms and quality of life and more studies underway. Future care planning provides a framework for discussing a range of palliative care problems with patients and their families. This approach can be introduced at any time during the patient's journey of care and ideally well in advance of end-of-life care. Future care planning is applicable to a wide range of patients with advanced heart disease and could be delivered systematically by cardiology teams at the time of an unplanned hospital admission, akin to cardiac rehabilitation for myocardial infarction. Integrating cardiology care and palliative care can benefit many patients with advanced heart disease at increased risk of death or hospitalisation. Larger, randomised trials are needed to assess the impact on patient outcomes and experiences. Published by the BMJ Publishing Group Limited.

A major limitation of past work linking area socioeconomic conditions to health in mid-life has been the reliance on single point in time measurement of area. Using the MRC National Survey of Health and Development, this study for the first time linked place of residence at three major life periods of childhood (1950), young adulthood (1972), and mid-life (1999) to area-socioeconomic data from the nearest census years. Using objective measures of physical capability as the outcome, the purpose of this study was to highlight four methodological challenges of attrition bias, secular changes in socio-economic measures, historical data availability, and changing reporting units over time. In general, standing balance and chair rise time showed clear cross-sectional associations with residing in areas with high deprivation. However, it was the process of overcoming the methodological challenges, which led to the conclusion that in this example percent low social class occupations was the most appropriate measure to use when extending cross-sectional analysis of standing balance and chair rise to life course investigation.

To determine the short-term outcomes of babies for whom clinicians or parents discussed the limitation of life-sustaining treatment (LST). Prospective multicentre observational study. Two level 3, six level 2 and one level 1 neonatal units in the North-East London Neonatal Network. A total of 87 babies including 68 for whom limiting LST was discussed with parents and 19 babies died without discussion of limiting LST in the labour ward or neonatal unit. Final decision reached after discussions about limiting LST and neonatal unit outcomes (death or survived to discharge) for babies. Withdrawing LST, withholding LST and do not resuscitate (DNR) order was discussed with 48, 16 and 4 parents, respectively. In 49/68 (72%) cases decisions occurred in level 3 and 19 cases in level 2 units. Following the initial discussions, 34/68 parents made the decision to continue LST. In 33/68 cases, a second opinion was obtained. The parents of 14/48 and 2/16 babies did not agree to withdraw and withhold LST, respectively. Forty-seven out of 87 babies (54%) died following limitation of LST, 28/87 (32%) died receiving full intensive care support, 5/87 (6%) survived following a decision to limit LST and 7/87 (8%) babies survived following decision to continue LST. A significant proportion of parents chose to continue treatment following discussions regarding limiting LST for their babies, and a proportion of these babies survived to neonatal unit discharge. The long-term outcomes of babies who survive following limiting LST discussion need to be investigated. Published by the BMJ Publishing Group Limited.

Economic Studies in Motor Neurone Disease: A Systematic Methodological Review.
Moore, Alan; Young, Carolyn A; Hughes, Dyfrig A
2017-04-01
Motor neurone disease (MND) is a devastating condition which greatly diminishes patients' quality of life and limits life expectancy. Health technology appraisals of future interventions in MND need robust data on costs and utilities. Existing economic evaluations have been noted to be limited and fraught with challenges. The aim of this study was to identify and critique methodological aspects of all published economic evaluations, cost studies, and utility studies in MND. We systematically reviewed all relevant published studies in English from 1946 until January 2016, searching the databases of Medline, EMBASE, Econlit, NHS Economic Evaluation Database (NHS EED) and the Health Economics Evaluation Database (HEED). Key data were extracted and synthesised narratively. A total of 1830 articles were identified, of which 15 economic evaluations, 23 cost and 3 utility studies were included. Most economic studies focused on riluzole (n = 9). Six studies modelled the progressive decline in motor function using a Markov design but did not include mutually exclusive health states. Cost estimates for a number of evaluations were based on expert opinion and were hampered by high variability and location-specific characteristics. Few cost studies reported disease-stage-specific costs (n = 3) or fully captured indirect costs. Utilities in three studies of MND patients used the EuroQol EQ-5D questionnaire or standard gamble, but included potentially unrepresentative cohorts and did not consider any health impacts on caregivers. Economic evaluations in MND suffer from significant methodological issues such as a lack of data, uncertainty with the disease course and use of inappropriate modelling framework. Limitations may be addressed through the collection of detailed and representative data from large cohorts of patients.

Timely communication about life expectancy and end-of-life care is crucial for ensuring good patient quality-of-life at the end of life and a good quality of death. This article describes the protocol for a multisite randomised controlled trial of a nurse-led communication support programme to facilitate patients' and caregivers' efforts to communicate about these issues with their healthcare team. This NHMRC-sponsored trial is being conducted at medical oncology clinics located at/affiliated with major teaching hospitals in Sydney, Australia. Patients with advanced, incurable cancer and life expectancy of less than 12 months will participate together with their primary informal caregiver where possible. Guided by the self-determination theory of health-behaviour change, the communication support programme pairs a purpose-designed Question Prompt List (QPL-an evidence-based list of questions patients/caregivers can ask clinicians) with nurse-led exploration of QPL content, communication challenges, patient values and concerns and the value of early discussion of end-of-life issues. Oncologists are also cued to endorse patient and caregiver question asking and use of the QPL. Behavioural and self-report data will be collected from patients/caregivers approximately quarterly for up to 2.5 years or until patient death, after which patient medical records will be examined. Analyses will examine the impact of the intervention on patients' and caregivers' participation in medical consultations, their self-efficacy in medical encounters, quality-of-life, end-of-life care receipt and quality-of-death indicators. Approvals have been granted by the human ethics review committee of Royal Prince Alfred Hospital and governance officers at each participating site.

Retired flies, hidden plateaus, and the evolution of senescence in Drosophila melanogaster.
Curtsinger, James W
2016-06-01
Late-life plateaus in age-specific mortality have been an evolutionary and biodemographic puzzle for decades. Although classic theory on the evolution of senescence predicts late-life walls of death, observations in experimental organisms document the opposite trend: a slowing in the rate of increase of mortality at advanced ages. Here, I analyze published life-history data on individual Drosophila melanogaster females and argue for a fundamental change in our understanding of mortality in this important model system. Mortality plateaus are not, as widely assumed, exclusive to late life, and are not explained by population heterogeneity-they are intimately connected to individual fecundity. Female flies begin adult life in the working stage, a period of active oviposition and low but accelerating mortality. Later they transition to the retired stage, a terminal period characterized by limited fecundity and relatively constant mortality. Because ages of transition differ between flies, age-synchronized cohorts contain a mix of working and retired flies. Early- and mid-life plateaus are obscured by the presence of working flies, but can be detected when cohorts are stratified by retirement status. Stage-specificity may be an important component of Drosophila life-history evolution. © 2016 The Author(s). Evolution © 2016 The Society for the Study of Evolution.
End-of-Life Care for Undocumented Immigrants With Advanced Cancer: Documenting the Undocumented.
Jaramillo, Sylvia; Hui, David
2016-04-01
There are approximately 11.1 million undocumented immigrants in the United States, with a majority being Latino. Cancer is now the leading cause of death in Latinos. There is little research guiding providers on how to deliver optimal end-of-life care in this population. We describe a case of an undocumented Latino patient with advanced cancer, and provide a review of the literature on end-of-life care in undocumented immigrants. Our patient encountered many challenges as he navigated through the healthcare system in the last months of life. These included delayed diagnosis, limited social support, financial issues, fear of deportation, and language and cultural barriers, which resulted in significant physical and psychological distress. Within the undocumented patient population, there is often a lack of advance care planning, prognostic understanding, mistrust, religious practices, and cultural beliefs that may affect decision making. Given the growing number of undocumented immigrants in the United States, it is important for clinicians and policy makers to have a better understanding of the issues surrounding end-of-life care for undocumented immigrants, and work together to improve the quality of life and quality of end-of-life care for these disadvantaged individuals.

social inequalities in health are believed to arise in part because individuals make use of social and economic resources in order to improve survival. In recent years, health literacy has received increased attention as a factor that can help explain differences in health outcomes. However, examination of life course predictors of health literacy has been limited. life course data from the Wisconsin Longitudinal Study 1957-2011 were used to examine predictors of health literacy in old age (N = 2,122), using the Newest Vital Sign. Generalised structural equation modelling was used to model pathways to health literacy. predictors of health literacy included educational attainment, and adolescent cognitive and non-cognitive skills, and, in men, rate of cognitive decline from middle to later life. numerous studies have documented health literacy issues among older adults, and recommendations have been made for ways to improve health literacy for this population. This study reports on risk factors across the life course that are associated with health literacy later in life, identifying possible intervention targets to reduce risk of poor health as people age. Our results suggest that a range of life course factors, beginning in early life, predict health literacy. Further research studying health literacy over the life course is warranted. © The Author 2016. Published by Oxford University Press on behalf of the British Geriatrics Society.

Over the life course, we are invariably faced with some form of adversity. The process of positively adapting to adverse events is known as 'resilience'. Despite the acknowledgement of 2 common components of resilience, that is, adversity and positive adaptation, no consensus operational definition has been agreed. Resilience operationalisations have been reviewed in a cross-sectional context; however, a review of longitudinal methods of operationalising resilience has not been conducted. The present study conducts a systematic review across Scopus and Web of Science capturing studies of ageing that posited operational definitions of resilience in longitudinal studies of ageing. Thirty-six studies met inclusion criteria. Non-acute events, for example, cancer, were the most common form of adversity identified and psychological components, for example, the absence of depression, the most common forms of positive adaptation. Of the included studies, 4 used psychometrically driven methods, that is, repeated administration of established resilience metrics, 9 used definition-driven methods, that is, a priori establishment of resilience components and criteria, and 23 used data-driven methods, that is, techniques that identify resilient individuals using latent variable models. Acknowledging the strengths and limitations of each operationalisation is integral to the appropriate application of these methods to life course and longitudinal resilience research.

Pulmonary arterial hypertension (PAH) causes profound functional limitations and poor quality of life. Yet, there is only a limited literature available on the role of exercise training. This paper systematically reviews the effects of exercise training on exercise capacity in PAH. A systematic search of databases (PubMed, CINAHL, CENTRAL, Web of Science and PEDRo) was undertaken for English language articles published between 1(st) January 1980 and 31(st) March 2015. Quality rating for all articles was done using the Downs and Black scoring system. Fifteen articles of good (n=4), moderate (n=6) and poor (n=5) quality were included in the review. Exercise interventions included aerobic, resistance, inspiratory muscle training or a combination, for 6-18 weeks. Improvements were seen in exercise capacity (six minute walk distance (6MWD) and peak VO2) by 17-96m and 1.1-2.1ml/Kg/min, functional class by one class and quality of life, with minimal adverse events. There is evidence to recommend the use of exercise training as an adjunct to medical treatment in PAH. More clinical trials and research are required to assess the effects of different types of exercise programs in patients with PAH, while focussing on strong exercise endpoints to quantify the improvements seen with exercise training.

Decision-making, when providing care and treatment for a person with dementia at the end of life, can be complex and challenging. There is a lack of guidance available to support practitioners and family carers, and even those experienced in end of life dementia care report a lack of confidence in decision-making. It is thought that the use of heuristics (rules of thumb) may aid decision-making. The aim of this study is to identify whether heuristics are used in end of life dementia care, and if so, to identify the context in which they are being used. A narrative literature review was conducted taking a systematic approach to the search strategy, using the Centre for Reviews and Dissemination guidelines. Rapid appraisal methodology was used in order to source specific and relevant literature regarding the use of heuristics in end of life dementia care. A search using terms related to dementia, palliative care and decision-making was conducted across 4 English language electronic databases (MEDLINE, EMBASE, PsycINFO and CINAHL) in 2015. The search identified 12 papers that contained an algorithm, guideline, decision tool or set of principles that we considered compatible with heuristic decision-making. The papers addressed swallowing and feeding difficulties, the treatment of pneumonia, management of pain and agitation, rationalising medication, ending life-sustaining treatment, and ensuring a good death. The use of heuristics in palliative or end of life dementia care is not described in the research literature. However, this review identified important decision-making principles, which are largely a reflection of expert opinion. These principles may have the potential to be developed into simple heuristics that could be used in practice. Published by the BMJ Publishing Group Limited.

To explore the association between unexpected potentially disruptive life events in a patient or family member that may challenge an individual's ability to take medications as prescribed and the discontinuation of evidence-based medications for common, chronic conditions. Understanding the relationship between medication adherence and life stressors, especially those that can be identified using administrative data, may help identify patients at risk of non-adherence. Observational self-controlled case-crossover design. Individuals in a nationally representative US commercial health insurance database. Adult individuals who initiated an oral hypoglycaemic, antihypertensive and/or statin and subsequently stopped the medication for ≥90 days. Potentially disruptive life events among patients and their family members measured in the 30 days just before the medication was discontinued ('hazard period') compared with the 30 days before this period ('control period'). These events included personal injury, hospitalisation, emergency room visits, changes in insurance coverage, acute stress or acute anxiety. Among the 326 519 patients meeting study criteria who discontinued their chronic disease medications, 88 896 (27.2%) experienced at least one potentially disruptive life event. Newly experiencing an injury (OR: 1.26, 95% CI 1.12 to 1.42), an emergency room visit (OR: 1.19, 95% CI 1.13 to 1.26) and acute stress (OR: 1.19, 95% CI 1.08 to 1.31) were associated with discontinuation. Life events among patients' family members did not appear to be associated with medication discontinuation or occurred less frequently just prior to discontinuation. Potentially disruptive life events among individuals identified using routinely collected claims data are associated with discontinuation of chronic disease medications. Awareness of these events may help providers or payers identify patients at risk of non-adherence to maximise patient outcomes. Published by the BMJ Publishing Group Limited.

To examine quality of life and coping strategies among immigrant women living with chronic pain. Qualitative content analysis based on in-depth semistructured interviews. A clinic specifically targeting immigrants at a larger university hospital in Copenhagen, Denmark. Non-western female immigrant patients suffering from chronic pain (n=13). Experiences of the impact of chronic pain on quality of life. Chronic pain was perceived to have an extensive, adverse effect on all aspects of quality of life, including physical health, mental well-being and social relations. This included the ability to maintain activities of daily living and the ability to work. Chronic pain was further experienced as a cause of emotional distress, depression and altered personalities, which all had great consequences on women's social interactions, causing change and loss of social relations. A variety of coping strategies were used to cope with the pain, manage its consequences, and restore a level of health that would enable women to function and fulfil social roles. Many participants coped with the pain by altering everyday life, keeping daily activities to a minimum and taking pain-killing drugs, offering temporary relief. Seeking healthcare was another coping strategy used as an active means to assert agency and as a temporary distraction from pain. However, accessing healthcare also involved a risk of disagreement and disappointments. Chronic pain had a severe negative impact on quality of life and necessitated alterations in everyday life and active health-seeking strategies. Implications for practice imply a need for a more holistic approach to immigrant women with chronic pain, including a family-centred approach. Further research is needed to explore similarities or differences in and between populations with diverse ethnic, socioeconomic and psychosocial backgrounds, and to assess how ethnicity and culture might influence the experiences of chronic pain.

Cerebral palsy (CP) is the most common cause of motor disability in children and is often accompanied by sensory and/or cognitive impairment. The aim of this study was to characterise visual acuity impairment, perceptual visual dysfunction (PVD) and physical disability in a community-based sample of Bangladeshi children with CP and to assess the impact of these factors on the quality of life of the children. A key informant study was used to recruit children with CP from Sirajganj district. Gross Motor Function Classification System (GMFCS) levels and visual impairment were assessed by a physiotherapist and an optometrist, respectively. Assessments of visual perception were performed and standardised questionnaires were administered to each child's main carer to elicit indicators of PVD and parent-reported health-related quality of life. A generalised linear regression analysis was conducted to assess the determinants of the quality of life scores. 180 children were recruited. The median age was 8 years (IQR: 6-11 years); 112 (62%) were male; 57 (32%) had visual acuity impairment and 95 (53%) had some parent-reported PVD. In analyses adjusted for age, sex, GMFCS and acuity impairment, visual attention (p<0.001) and recognition/navigation (p<0.001) were associated with total health-related quality of life, and there were similar trends for total PVD score (p=0.006) and visual search (p=0.020). PVD is an important contributor in reducing quality of life in children with CP, independent of motor disability and acuity impairment. Better characterisation of PVD is important to help design interventions for affected children, which may improve their quality of life. Published by the BMJ Publishing Group Limited.

The combined effect of life-course influences on obesity development and thus their potential public health impact is unclear. We evaluated combined associations and predicted probabilities for early and adult life risk factors with central and general obesity in mid-adulthood. 1958 British birth cohort. 4629 males and 4670 females with data on waist circumference. 45 year obesity measured via waist circumference, waist-hip ratio (WHR) and BMI. At 45 years, approximately a third of the population were centrally obese and a quarter were generally obese. Three factors (parental overweight, maternal smoking during pregnancy and adult inactivity) were consistently associated with central and general obesity. Predicted probabilities for waist obesity increased from those with none to all three risk factors (0.15-0.33 in men; 0.19-0.39 in women (ptrend<0.001)), with a similar trend for general obesity. Additional factors (adult smoking, low fibre and heavy alcohol consumption) were associated with WHR obesity, although varying by gender. Prevalence of risk factors was higher in manual than non-manual groups: for example, in men 38% versus 25%, respectively, had ≥2 risk factors for waist and general obesity. Early-life and adult factors that are amenable to change are highly prevalent and accumulate in association with central and general obesity in mid-adulthood. The increase in probabilities for mid-adult obesity associated with cumulative levels of risk factors suggests the potential for public health impact. Published by the BMJ Publishing Group Limited.

Extend analyses of maternal mental health and infant growth in low- and middle-income countries (LMICs) to children through age eight years, and broaden analyses to cognitive and psychosocial outcomes. Community-based longitudinal cohort study in four LMICs (Ethiopia, India, Peru and Vietnam). Surveys and anthropometric assessments were carried out when the children were approximately ages 1, 5 and 8 years. Risk of maternal common mental disorders (rCMDs) was assessed with the Self-Reporting Questionnaire (SRQ)-20 (score ≥8). Rural and urban as well as low- and middle-income communities. 7722 mothers and their children. Child stunting and underweight (Z score ≤2 of height and weight for age), and <20th centile for: cognitive development (Peabody Picture Vocabulary Test), and the psychosocial outcomes self pride and life satisfaction. A high rate of rCMD, stunting and underweight was seen in the cohorts. After adjusting for confounders, significant associations were found between maternal rCMDs and growth variables in the first year of life, with persistence to age 8 years in India and Vietnam, but not in the other countries. India and Vietnam also showed significant associations between rCMDs and lower cognitive development. After adjustment, rCMD was associated with low life satisfaction in Ethiopia but not in the other cohorts. Associations of maternal rCMD in the first year of life with child outcomes varied across the study cohorts and, in some cases, persisted across the first 8 years of life of the child, and included growth, cognitive development and psychosocial domains.

There is little agreement about what constitutes good death or successful dying. The authors conducted a literature search for published, English-language, peer-reviewed reports of qualitative and quantitative studies that provided a definition of a good death. Stakeholders in these articles included patients, prebereaved and bereaved family members, and healthcare providers (HCPs). Definitions found were categorized into core themes and subthemes, and the frequency of each theme was determined by stakeholder (patients, family, HCPs) perspectives. Thirty-six studies met eligibility criteria, with 50% of patient perspective articles including individuals over age 60 years. We identified 11 core themes of good death: preferences for a specific dying process, pain-free status, religiosity/spirituality, emotional well-being, life completion, treatment preferences, dignity, family, quality of life, relationship with HCP, and other. The top three themes across all stakeholder groups were preferences for dying process (94% of reports), pain-free status (81%), and emotional well-being (64%). However, some discrepancies among the respondent groups were noted in the core themes: Family perspectives included life completion (80%), quality of life (70%), dignity (70%), and presence of family (70%) more frequently than did patient perspectives regarding those items (35%-55% each). In contrast, religiosity/spirituality was reported somewhat more often in patient perspectives (65%) than in family perspectives (50%). Taking into account the limitations of the literature, further research is needed on the impact of divergent perspectives on end-of-life care. Dialogues among the stakeholders for each individual must occur to ensure a good death from the most critical viewpoint-the patient's. Copyright © 2016 American Association for Geriatric Psychiatry.

Asian-Americans outlive whites by an average of nearly 8 years. By determining the sources of the Asian mortality advantage, we can pinpoint where there is the greatest potential for raising the life expectancy of whites and other groups in the USA. Our analyses include all Asian and white deaths in the USA between 2006 and 2010, from the Center for Disease Control. Using the International Classification of Diseases (V.10), we code causes of deaths into 19 categories, based on the most common causes as well as causes particularly relevant to racial differences. We then create life tables and apply a newly-developed demographic method to determine whether Asians have longer life expectancy because they are less likely than whites to die of causes of death that strike at younger ages, or because they tend to outlive whites regardless of cause of death. Nearly 90% of the Asian-white life expectancy gap is attributable to the fact that Asians tend to outlive whites regardless of the cause of death. The causes that contribute the most to the gap are heart disease (24%) and cancers (18%). Men contribute somewhat more to the gap than women do (55% vs 45%), primarily because Asian-white differences in mortality are greater among men than among women with respect to suicide, traffic accidents and accidental poisoning. For almost all causes of death, Asian victims tend to be older than white victims. The greatest potential for raising the life expectancy of whites to that of Asians, then, resides in efforts that effectively increase whites' average age at death for the most common causes of death.

Visible vascular and pigmentary conditions have a negative impact on children's and adolescents' quality of life (QoL). We sought to quantitate the effect of visible skin anomalies and their camouflage on QoL. In all, 41 patients, 5 years of age and older, were taught to use cosmetic camouflage. QoL was assessed using the Children's Dermatology Life Quality Index (CDLQI) before and 6 months after the intervention. Satisfaction and use were evaluated after 1 and 6 months. Baseline QoL scores revealed a small impact of vascular anomalies (CDLQI score 4.2) and a small to moderate effect of pigmentary anomalies (CDLQI score 6.1). Six months after the intervention, QoL improved in the study population as a whole (CDLQI score 5.1 vs 2.1, P<.001), with significant improvements documented for facial lesions and vascular malformations. Cosmetic camouflage was well tolerated and patients with pigmentary anomalies were more likely to continue using the products. Limitations include small study population, few male patients, cultural influences not addressed, and limited range of conditions. Children and teenagers with visible vascular and pigmentary anomalies experience an impairment of QoL that is abrogated by introduction to use of cosmetic camouflage.

Low-income and middle-income countries (LMICs) are experiencing a growing disease burden due to cardiovascular and other chronic non-communicable diseases. Interventions for the control of these diseases are paramount; however, these countries are faced with competing health and financial needs. There is an urgent need for quality evidence on cost-effective strategies to address these chronic diseases. We aim to synthesise the current literature on economic evaluations of interventions for primary and secondary cardiovascular disease prevention in LMICs. A systematic review of studies (published and unpublished) in LMICs up to 30 October 2016 will be conducted. The following databases will be searched: PubMed/MEDLINE, EMBASE, SCOPUS, CINAHL, Web of Science, EconLit, NHS Economic Evaluations Database (NHS EED). Data sources specific to African literature, such as the WHO AFROLIB, Africa Index Medicus and African Journals online (AJOL) as well as grey literature, will also be searched. 2 reviewers shall independently screen potential articles for inclusion and disagreements shall be resolved by consensus. Quality appraisal of studies shall be done using Drummond's checklist for economic evaluation of studies. A descriptive synthesis of the evidence obtained is planned. The primary outcomes will be costs per life years gained or unit of clinical outcome, cost per quality-adjusted life years or disability-adjusted life years. This systematic review protocol has been prepared according to the Preferred Reporting Items for Systematic reviews and Meta-analyses for Protocols (PRISMA-P) 2015 statement. Ethics approval is not required considering that this is a protocol for a systematic review of published studies.

Synthetic Biology: Engineering Living Systems from Biophysical Principles.
Bartley, Bryan A; Kim, Kyung; Medley, J Kyle; Sauro, Herbert M
2017-03-28
Synthetic biology was founded as a biophysical discipline that sought explanations for the origins of life from chemical and physical first principles. Modern synthetic biology has been reinvented as an engineering discipline to design new organisms as well as to better understand fundamental biological mechanisms. However, success is still largely limited to the laboratory and transformative applications of synthetic biology are still in their infancy. Here, we review six principles of living systems and how they compare and contrast with engineered systems. We cite specific examples from the synthetic biology literature that illustrate these principles and speculate on their implications for further study. To fully realize the promise of synthetic biology, we must be aware of life's unique properties. Copyright © 2017 Biophysical Society. Published by Elsevier Inc. All rights reserved.

Transsexual patients can only be diagnosed and treated at functional gender identity Units with provision of high quality care, development of clinical practice guidelines, and interdisciplinary working groups. The therapeutic process has three mainstays: initial psychological diagnostic evaluation and psychotherapy, endocrinological evaluation and hormone therapy, and sex reassignment surgery. Cross-sex hormone therapy is essential for the anatomical and psychological transition process in duly selected patients. Hormones help optimize real-life sex identity, improve quality of life, and limit psychiatric co-morbidities often associated to lack of treatment. Development of this clinical practice guideline addresses the need for implementing a coordinated action protocol for comprehensive health care for transgender people in the National Health System.

Distinct origins of the external carotid artery and the internal carotid artery (ICA) from the aortic arch have been rarely described, and represent an aberrant development of the aortic arches during fetal life. This anatomical variation is usually discovered incidentally; infrequently, an aneurysm of the cervical ICA might accompany this rare configuration. We describe one such case in a patient with Noonan syndrome who presented with pulsatile neck mass. The diagnostic features and management of the aneurysm and a review of the literature are presented. Published by the BMJ Publishing Group Limited.

Eye disorders in newborn infants (excluding retinopathy of prematurity).
Wan, Michael J; VanderVeen, Deborah K
2015-05-01
A screening eye examination is an essential part of the newborn assessment. The detection of many ocular disorders in newborn infants can be achieved through careful observation of the infant's visual behaviour and the use of a direct ophthalmoscope to assess the ocular structures and check the red reflex. Early diagnosis and subspecialty referral can have a critical impact on the prognosis for many ocular conditions, including potentially blinding but treatable conditions such as congenital cataracts, life-threatening malignancies such as retinoblastoma and harbingers of disease elsewhere such as sporadic aniridia and its association with the development of Wilms tumour.

Competence in chronic mental illness: the relevance of practical wisdom.
Widdershoven, Guy A M; Ruissen, Andrea; van Balkom, Anton J L M; Meynen, Gerben
2017-06-01
The concept of competence is central to healthcare because informed consent can only be obtained from a competent patient. The standard approach to competence focuses on cognitive abilities. Several authors have challenged this approach by emphasising the role of emotions and values. Combining cognition, emotion and values, we suggest an approach which is based on the notion of practical wisdom. This focuses on knowledge and on determining what is important in a specific situation and finding a balance between various values, which are enacted in an individual's personal life. Our approach is illustrated by two cases of patients with obsessive-compulsive disorder. Published by the BMJ Publishing Group Limited.

Improving the resiliency of healthcare workers is a national imperative, driven in part by healthcare workers having minimal exposure to the skills and culture to achieve work-life balance (WLB). Regardless of current policies, healthcare workers feel compelled to work more and take less time to recover from work. Satisfaction with WLB has been measured, as has work-life conflict, but how frequently healthcare workers engage in specific WLB behaviours is rarely assessed. Measurement of behaviours may have advantages over measurement of perceptions; behaviours more accurately reflect WLB and can be targeted by leaders for improvement. 1. To describe a novel survey scale for evaluating work-life climate based on specific behavioural frequencies in healthcare workers.2. To evaluate the scale's psychometric properties and provide benchmarking data from a large healthcare system.3. To investigate associations between work-life climate, teamwork climate and safety climate. Cross-sectional survey study of US healthcare workers within a large healthcare system. 7923 of 9199 eligible healthcare workers across 325 work settings within 16 hospitals completed the survey in 2009 (86% response rate). The overall work-life climate scale internal consistency was Cronbach α=0.790. t-Tests of top versus bottom quartile work settings revealed that positive work-life climate was associated with better teamwork climate, safety climate and increased participation in safety leadership WalkRounds with feedback (p<0.001). Univariate analysis of variance demonstrated differences that varied significantly in WLB between healthcare worker role, hospitals and work setting. The work-life climate scale exhibits strong psychometric properties, elicits results that vary widely by work setting, discriminates between positive and negative workplace norms, and aligns well with other culture constructs that have been found to correlate with clinical outcomes.

Higher levels of alcohol consumption have been observed in the UK armed forces compared with the general population. For some, this may increase the risk of using alcohol as a coping strategy when adjusting to multiple life events occurring when moving back into civilian life. A systematic review was conducted to determine the effectiveness of alcohol brief interventions for military personnel during transition. Electronic databases including Medline, Central, Healthcare Management Information Consortium (HMIC) and Embase, and grey literature, were searched. Two reviewers independently assessed potential studies for inclusion, extracted data and assessed quality of selected articles using an established instrument. Ten studies met criteria for inclusion. Studies were synthesised narratively. Interventions were heterogeneous, and bias within studies may have acted to increase or decrease their reported effectiveness. The findings suggest some evidence for effectiveness of self-administered web-based interventions, involving personalised feedback over a number of sessions, and system-level electronic clinical reminders. All studies were from the USA. Delivery of interventions by a clinician during motivational interviews was most effective for those with post-traumatic stress disorder symptoms. A UK trial of web-based interventions with personalised feedback is recommended. Published by the BMJ Publishing Group Limited.

2014-05-01
Medical errors frequently contribute to morbidity and mortality. Prehospital emergency medicine is prone to incidents that can lead to immediate deadly consequences. Critical incident reporting can identify typical problems and be the basis for structured risk management in order to reduce and mitigate these incidents. We set up a free access internet website for German-speaking countries, with an anonymous reporting system for emergency medical services personnel. After a 7-year study period, an expert team analysed and classified the incidents into staff related, equipment related, organisation and tactics, or other. 845 reports were entered in the study period. Physicians reported 44% of incidents, paramedics 42%. Most patients were in a life-threatening or potentially life-threatening situation (82%), and only 53% of all incidents had no influence on the outcome of the patient. Staff-related problems were responsible for 56% of the incidents, when it came to harm, 78% of these incidents were staff related. Incident reporting in prehospital emergency medicine can identify system weaknesses. Most of the incidents were reported during care of patients in life-threatening conditions with a high impact on patient outcome. Staff-related problems contributed to the most frequent and most severe incidents. Published by the BMJ Publishing Group Limited.

For the past 30 years, there has been a steady increase in the number of female physicians, but the relationship between their romantic lives and their pattern of training has been inadequately reported. This study was designed to investigate the interrelationships between medical training, quality of life, and the attitudes that female residents have toward romance. Of the 106 female medical residents at our medical center in 2009, a total of 78 residents (73.6%) were enrolled for the study. Structured questionnaires (Cronbach α = 0.878), which included questions about female resident quality of life, attitude toward spousal choice, and the impact of programmed professional medical training, were self-administered through an anonymous process. Female residents, especially ward-care specialists, were determined to have excessively long working hours (84.6% > 88 work hours/week), insufficient and irregular sleep (44.9%), and inadequate personal time (73.1% < 24 hours/week) on average. Of the 48 residents with ongoing romances, 87.5% (n = 40) of romantic partners were physicians and 58.3% (n = 28) initiated their relationships when they were medical students, but exhibited no preferential dating of senior medical students or physicians. Factors affecting the choice of spouses included time limitations, a limited circle of friends, differences in values, and work-related stress. Those presumptive factors influencing romance between the assumed partner being a doctor or a "nondoctor" were significantly different with regard to lack of time (p = 0.002), values (p < 0.001), work-related stress (p < 0.001), and family background (p = 0.004). Romance and quality of life were significantly influenced by the pattern of medical training in female residents. Setting duty-hour limits and initiating a new hobby were determined to be potentially beneficial to their quality of life and attitudes toward romance. Copyright © 2012. Published by Elsevier B.V.

Skin grafts are utilized in dermatology to reconstruct a defect secondary to surgery or trauma of the skin. Common indications for skin grafts include surgical removal of cutaneous malignancies, replacement of tissue after burns or lacerations, and hair transplantation in alopecia. Skin grafts may be cosmetically displeasing, functionally limiting, and significantly impact patient's quality-of-life. There is limited published data regarding skin graft revision to enhance aesthetics and function. Here, we present a case demonstrating excellent aesthetic and functional outcome after fractionated carbon dioxide (CO2) laser skin graft revision surgery and review of the medical literature on laser skin graft revision techniques.

Dyspnoea and chest pain are signs shared with multiple pathologies ranging from the benign to life-threatening diseases. Gut feelings such as the sense of alarm and the sense of reassurance are known to play a substantial role in the diagnostic reasoning of general practitioners (GPs). A Gut Feelings Questionnaire (GFQ) has been validated to measure the GP's sense of alarm. A French version of the GFQ is available following a linguistic validation procedure. The aim of the study is to calculate the diagnostic test accuracy of a GP's sense of alarm when confronted with dyspnoea and chest pain. Prospective observational study. Patients aged between 18 and 80 years, consulting their GP for dyspnoea and/or thoracic pain will be considered for enrolment in the study. These GPs will have to complete the questionnaire immediately after the consultation for dyspnoea and/or thoracic pain. The follow-up and the final diagnosis will be collected 4 weeks later by phone contact with the GP or with the patient if their GP has no information. Life-threatening and non-life-threatening diseases have previously been defined according to the pathologies or symptoms in the (ICPC2) International Collegiate Programming Contest classification. Members of the research team, blinded to the actual outcomes shown on the index questionnaire, will judge each case in turn and will, by consensus, classify the expected outcomes as either life-threatening or non-life-threatening diseases. The sensitivity, the specificity, the positive and negative likelihood ratio of the sense of alarm will be calculated from the constructed contingency table. This study was approved by the ethical committee of the University de Bretagne Occidentale. A written informed consent form will be signed and dated by GPs and patients at the beginning of the study. The results will be published in due course. Published by the BMJ Publishing Group Limited.

Early-late life trade-offs and the evolution of ageing in the wild.
Lemaître, Jean-François; Berger, Vérane; Bonenfant, Christophe; Douhard, Mathieu; Gamelon, Marlène; Plard, Floriane; Gaillard, Jean-Michel
2015-05-07
Empirical evidence for declines in fitness components (survival and reproductive performance) with age has recently accumulated in wild populations, highlighting that the process of senescence is nearly ubiquitous in the living world. Senescence patterns are highly variable among species and current evolutionary theories of ageing propose that such variation can be accounted for by differences in allocation to growth and reproduction during early life. Here, we compiled 26 studies of free-ranging vertebrate populations that explicitly tested for a trade-off between performance in early and late life. Our review brings overall support for the presence of early-late life trade-offs, suggesting that the limitation of available resources leads individuals to trade somatic maintenance later in life for high allocation to reproduction early in life. We discuss our results in the light of two closely related theories of ageing-the disposable soma and the antagonistic pleiotropy theories-and propose that the principle of energy allocation roots the ageing process in the evolution of life-history strategies. Finally, we outline research topics that should be investigated in future studies, including the importance of natal environmental conditions in the study of trade-offs between early- and late-life performance and the evolution of sex-differences in ageing patterns. © 2015 The Author(s) Published by the Royal Society.

Exposure to early-life adversity may program brain function to prepare individuals for adaptation to matching environmental contexts. In this study we tested this hypothesis in more detail by examining the effects of early-life stress - induced by raising offspring with limited nesting and bedding material from postnatal days 2-9 - in various behavioral tasks and on synaptic function in adult mice. Early-life stress impaired adult performance in the hippocampal dependent low-arousing object-in-context recognition memory task. This effect was absent when animals were exposed to a single stressor before training. Early-life stress did not alter high-arousing context and auditory fear conditioning. Early-life stress-induced behavioral modifications were not associated with alterations in the dendritic architecture of hippocampal CA1 pyramidal neurons or principal neurons of the basolateral amygdala. However, early-life stress reduced the ratio of NMDA to AMPA receptor-mediated excitatory postsynaptic currents and glutamate release probability specifically in hippocampal CA1 neurons, but not in the basolateral amygdala. These ex vivo effects in the hippocampus were abolished by acute glucocorticoid treatment. Our findings support that early-life stress can hamper object-in-context learning via pre- and postsynaptic mechanisms that affect hippocampal function but these effects are counteracted by acute stress or elevated glucocorticoid levels.

Little data exist with regard to the effect of peripartum cardiomyopathy (PPCM) on quality of life. The aim of this study was to determine the impact of PPCM on quality of life and emotional well-being. We sought to determine the feasibility of using social media to perform quality of life research. We conducted a study using a survey distributed to established members of "Peripartum Cardiomyopathy Survivors" support group on the social networking site Facebook. A total of 116 women completed the survey (age 36 ± 6.4 years; 91% white, 75% married, 46% college educated), with 4.9 ± 0.5 years (range 0.02 to 24 years) since the initial diagnosis. Most women (41%) never returned to their baseline level of activity, and 28% discontinued their job because of the diagnosis. Most respondents (56%) were not limited or only slightly limited by heart failure symptoms over the past 2 months. Most respondents (56%) never returned to their baseline emotionally after the diagnosis of PPCM, and most patients (73%) were dissatisfied with their current level of heart failure symptoms. Most patients (67%) felt discouraged frequently (more than several times per month) because of heart failure. Only 26% of women were satisfied with the counseling they received from their providers. The emotional and physical burden of PPCM on young mothers with PPCM years after the diagnosis is striking. Identifying strategies that promote better emotional health and potential treatment strategies may be required. Copyright © 2016. Published by Elsevier Inc.

To conduct a systematic review of evidence surrounding the effects of exercise training on physical fitness, mobility, fatigue, and health-related quality of life in adults with multiple sclerosis (MS). The databases included EMBASE, 1980 to 2011 (wk 12); Ovid MEDLINE and Ovid OLDMEDLINE, 1947 to March (wk 3) 2011; PsycINFO, 1967 to March (wk 4) 2011; CINAHL all-inclusive; SPORTDiscus all-inclusive; Cochrane Library all-inclusive; and Physiotherapy Evidence Database all-inclusive. The review was limited to English-language studies (published before December 2011) of people with MS that evaluated the effects of exercise training on outcomes of physical fitness, mobility, fatigue, and/or health-related quality of life. One research assistant extracted data and rated study quality. A second research assistant verified the extraction and quality assessment. From the 4362 studies identified, 54 studies were included in the review. The extracted data were analyzed using a descriptive approach. There was strong evidence that exercise performed 2 times per week at a moderate intensity increases aerobic capacity and muscular strength. The evidence was not consistent regarding the effects of exercise training on other outcomes. Among those with mild to moderate disability from MS, there is sufficient evidence that exercise training is effective for improving both aerobic capacity and muscular strength. Exercise may improve mobility, fatigue, and health-related quality of life. Copyright © 2013 American Congress of Rehabilitation Medicine. Published by Elsevier Inc. All rights reserved.

This study compared youth and parent-proxy reports of health-related quality of life (HRQoL) among youth with inflammatory bowel disease (IBD) to published comparison group data and examined concordance between youth and parent-proxy reports of HRQoL. One hundred thirty-six youth and parent-proxy reports on the PedsQL 4.0 Generic Core Scales were compared to published data from chronically ill, acutely ill, and healthy comparison groups using independent samples t-tests. Reporter agreement was examined using paired samples t-tests and intraclass correlations (ICCs). Youth with IBD reported lower psychosocial functioning than the healthy comparison group, higher physical and social functioning than the chronically ill group, and lower school functioning than all published comparison groups. Parent-proxy reports of youth HRQoL were higher than the chronically ill group, but lower than the healthy group on all scales except psychosocial functioning. Youth with active IBD reported lower physical health domain scores than youth with inactive disease. Concordance between youth and parent-proxy reports was moderate, with the lowest agreement in school and social functioning. Youth with IBD and their parents rate HRQoL as lower than healthy youth but do not perceive the impact of IBD to be as limiting as in other chronic conditions. Youth report suggests that IBD may be particularly detrimental to HRQoL in the school functioning domain. Moderate agreement between parent and youth reports substantiates continued use of multiple informants in studies of pediatric HRQoL.
Disciplinary perspectives on later-life migration in the core journals of social gerontology.
Walters, William H; Wilder, Esther I
2003-10-01
The authors examine the bibliographic structure of recent research on later-life migration, highlighting the contributions of particular journals and disciplines. The authors identify the primary journals publishing research in this area, including a set of four core journals within the field of social gerontology. They evaluate the disciplinary affiliations of authors publishing in the core journals and the extent to which those journals cite relevant research published elsewhere. Geographical and economic perspectives on later-life migration are underrepresented within the core journals of social gerontology. In particular, major articles published outside the core journals are seldom cited within those journals. Although the core journals of social gerontology account for over a third of the recent literature on later-life migration, they present only a partial (chiefly sociological) perspective on the subject.

Despite the extensive knowledge of pollen limitation in angiosperms, its assessment within tropical forests is still limited. Especially lacking are large scale comparisons of species within this biome – one that is highly diverse but also becoming increasingly threatened. In fact, many tropical plant species depend upon pollinators for reproduction but evaluation of the impact of this dependence via different levels of pollination specialization has yet to be made at the biome scale. We assessed the occurrence and magnitude of pollen limitation for species in the Brazilian Atlantic forest and tested the association of pollination specialization, breeding system, and life habit with pollination efficiency. We compiled data from studies published between 1985 and 2012. We calculated species' effect size (d) from data on fruit set after hand cross-pollination and natural pollination and conducted standard and phylogenetically independent meta-analysis. Overall pollen limitation was moderate, with magnitude of 0.50, and 95% confidence interval [0.37, 0.62] for 126 species. Pollen limitation was observed in 39% of species. Pollination specialization was the factor that best explained the occurrence of pollen limitation. Specifically, phenotypic and ecological specialists (plants with zygomorphic flowers and pollinated by one species of pollinator, respectively) had higher pollen limitation than generalist plants (actinomorphic flowers and pollination by two or more species). Functional generalists (plants pollinated by three or more functional groups) were not pollen limited. On the other hand, breeding system and life habit were not associated to pollen limitation. Pollen limitation was observed in the Atlantic forest and its magnitude was comparable to that for angiosperms as a whole. The finding that pollination specialization was the strongest predictor of pollen limitation suggests that specialist plants in this biome may be most prone to the reproductive failure as a result of pollinator loss.

High serum uric acid (sUA) has been associated with increased mortality risks, but its clinical treatment varied with potential side effects. The role of physical activity has received limited attention. A cohort, consisting of 467 976 adults, who went through a standard health screening programme, with questionnaire and fasting blood samples, was successively recruited between 1996 and 2008. High sUA is defined as uric acid above 7.0 mg/dL. Leisure time physical activity level was self-reported, with fully active defined as those with 30 min per day for at least 5 days a week. National death file identified 12 228 deaths with a median follow-up of 8.5 years. Cox proportional model was used to analyse HRs, and 12 variables were controlled, including medical history, life style and risk factors. High sUA constituted one quarter of the cohort (25.6%). Their all-cause mortality was significantly increased [HR: 1.22 (1.15-1.29)], with much of the increase contributed to by the inactive (HR: 1.27 (1.17-1.37)), relative to the reference group with sUA level of 5-6 mg/dL. When they were fully active, mortality risks did not increase, but decreased by 11% (HR: 0.89 (0.82-0.97)), reflecting the benefits of being active was able to overcome the adverse effects of high sUA. Given the same high sUA, a 4-6 years difference in life expectancy was found between the active and the inactive. Physical activity is a valuable alternative to pharmacotherapy in its ability to reduce the increases in mortality risks from high sUA. By being fully active, exercise can extend life span by 4-6 years, a level greater than the 1-4 years of life-shortening effect from high sUA. Published by the BMJ Publishing Group Limited.

To evaluate the clinical and cost-effectiveness of a new blended dental contract incentivising improved oral health compared with a traditional dental contract based on units of dental activity (UDAs). Non-randomised controlled study. Six UK primary care dental practices, three working under a new blended dental contract; three matched practices under a traditional contract. 550 new adult patients. A new blended/incentive-driven primary care dentistry contract and service delivery model versus the traditional contract based on UDAs. Primary outcome was as follows: percentage of sites with gingival bleeding on probing. Secondary outcomes were as follows: extracted and filled teeth (%), caries (International Caries Detection and Assessment System (ICDAS)), oral health-related quality of life (Oral Health Impact Profile-14 (OHIP-14)). Incremental cost-effective ratios used OHIP-14 and quality adjusted life years (QALYs) derived from the EQ-5D-3L. At 24 months, 291/550 (53%) patients returned for final assessment; those lost to follow-up attended 6.46 appointments on average (SD 4.80). The primary outcome favoured patients in the blended contract group. Extractions and fillings were more frequent in this group. Blended contracts were financially attractive for the dental provider but carried a higher cost for the service commissioner. Differences in generic health-related quality of life were negligible. Positive changes over time in oral health-related quality of life in both groups were statistically significant. This is the first UK study to assess the clinical and cost-effectiveness of a blended contract in primary care dentistry. Although the primary outcome favoured the blended contract, the results are limited because 47% patients did not attend at 24 months. This is consistent with 39% of adults not being regular attenders and 27% only visiting their dentist when they have a problem. Promotion of appropriate attendance, especially among those with high need, necessitates being factored into recruitment strategies of future studies. Published by the BMJ Publishing Group Limited.

The Antarctic black meristematic fungus Cryomyces antarcticus CCFEE 515 occurs endolithically in the McMurdo Dry Valleys of Antarctica, one of the best analogue for Mars environment on Earth. To date, this fungus is considered one of the best eukaryotic models for astrobiological studies and has been repeatedly selected for space experiments in the last decade. The obtained results are reviewed here, with special focus on responses to space relevant irradiation, UV radiation, and both sparsely and densely ionizing radiation, which represent the major injuries for a putative space-traveller. The remarkable resistance of this model organism to space stress, its radioresistance in particular, and mechanisms involved, significantly contributed to expanding our concept of limits for life and provided new insights on the origin and evolution of life in planetary systems, habitability, and biosignatures for life detection as well as on human protection during space missions.

Climate change in fish: effects of respiratory constraints on optimal life history and behaviour.
Holt, Rebecca E; Jørgensen, Christian
2015-02-01
The difference between maximum metabolic rate and standard metabolic rate is referred to as aerobic scope, and because it constrains performance it is suggested to constitute a key limiting process prescribing how fish may cope with or adapt to climate warming. We use an evolutionary bioenergetics model for Atlantic cod (Gadus morhua) to predict optimal life histories and behaviours at different temperatures. The model assumes common trade-offs and predicts that optimal temperatures for growth and fitness lie below that for aerobic scope; aerobic scope is thus a poor predictor of fitness at high temperatures. Initially, warming expands aerobic scope, allowing for faster growth and increased reproduction. Beyond the optimal temperature for fitness, increased metabolic requirements intensify foraging and reduce survival; oxygen budgeting conflicts thus constrain successful completion of the life cycle. The model illustrates how physiological adaptations are part of a suite of traits that have coevolved. © 2015 The Author(s) Published by the Royal Society. All rights reserved.
Menstrual questionnaires for clinical and research use.
Matteson, Kristen A
2017-04-01
Patient-reported outcome measures (PROMs) have the potential to be extremely valuable in the clinical care delivery for women who report heavy menstrual bleeding (HMB). Increasingly, studies on HMB have incorporated PROMs to evaluate the impact of bleeding on quality of life. These measures have included semiquantitative charts and pictograms, questionnaires to assess symptoms and impact on quality of life, and health-related quality of life questionnaires. Recent systematic reviews have highlighted inconsistency of outcome measurement across studies on HMB as a challenge limiting the interpretability of the body of literature and the ability to generate consensus on the relative effectiveness of treatment options. Consequently, research initiatives and international collaborations are working to harmonize outcome measurement. Harmonizing the use of questionnaires in research and clinical care has the potential to improve patient-centered care delivery for women with HMB and improve the generation of patient-focused evidence-based guidelines for the evaluation and treatment of HMB.

Fast life history traits promote invasion success in amphibians and reptiles.
Allen, William L; Street, Sally E; Capellini, Isabella
2017-02-01
Competing theoretical models make different predictions on which life history strategies facilitate growth of small populations. While 'fast' strategies allow for rapid increase in population size and limit vulnerability to stochastic events, 'slow' strategies and bet-hedging may reduce variance in vital rates in response to stochasticity. We test these predictions using biological invasions since founder alien populations start small, compiling the largest dataset yet of global herpetological introductions and life history traits. Using state-of-the-art phylogenetic comparative methods, we show that successful invaders have fast traits, such as large and frequent clutches, at both establishment and spread stages. These results, together with recent findings in mammals and plants, support 'fast advantage' models and the importance of high potential population growth rate. Conversely, successful alien birds are bet-hedgers. We propose that transient population dynamics and differences in longevity and behavioural flexibility can help reconcile apparently contrasting results across terrestrial vertebrate classes. © 2017 The Authors.

This article analyses the concept of narrative empathy in illness memoirs. These texts negotiate the narrative identity of an autobiographer as he or she recounts the disruptive experience of illness, an experience in which physical and emotional traces dramatically and definitively shape our sense of self. While narrative emotions are certainly deployed in these autobiographies in order to connect with the readers and promote social change, this empathic connection is not so much aimed at arousing compassion but rather more positive emotions on the experience of illness. I will explore the emotional representations of cancer in Arthur Frank's At the Will of the Body (1991) and Kathlyn Conway's Ordinary Life: A Memoir of Illness (1997), focusing on the identity strategies these authors use in order to become affirmative models of disability and illness, showing the damaging effects not of disease or impairment but, rather, of the cultural mythologies that interpret those conditions in reductive or disparaging ways.

Culture and spirituality: essential components of palliative care.
Speck, Peter
2016-06-01
Palliative care advocates a holistic, multiprofessional approach to the care of people with life-threatening disease. In addition to the control of physical symptoms attention should also be paid to psychosocial, cultural and spiritual aspects of the patient's experience of illness. Guidance documents and research evidence reflect the complexity of the patient's journey and the need to regularly assess these areas of need over time. Cultural background can shape how patients respond to life-threatening illness, as can the beliefs held by the patients, whether religious or more broadly spiritual. Research evidence shows the importance of identifying and addressing cultural and spiritual aspects of care held by patients, families and staff. These are often neglected in clinical practice due to the focus on biomedical concerns and staff discomfort in engaging with beliefs and culture. Recent studies have highlighted gaps in the research, and some methodological difficulties and indicate many patients welcome healthcare staff enquiring about the importance of their beliefs and culture. Identifying research priorities is necessary to guide future research and strengthen the evidence base. Published by the BMJ Publishing Group Limited.

Dutch physicians on the role of the family in continuous sedation.
van Tol, Donald G; Kouwenhoven, Pauline; van der Vegt, Bea; Weyers, Heleen
2015-03-01
In order to relieve intractable suffering of a terminal patient, doctors may decide to continuously sedate a patient until the end of life. Little research is done on the role the family plays during the process of continuous sedation. This study aims to get a view of doctors' experiences with continuous sedation, and the role of the family throughout that process. We held in-depth interviews with 48 doctors (19 general practitioners, 16 nursing home doctors and 18 medical specialists). Participants were selected varying in experience and opinions concerning end-of-life decisions. Dutch physicians experience the role of family in continuous sedation as important and potentially difficult. Difficulties may rise especially during the final stages when the patient is no longer conscious and family members are waiting for death to come. Disagreement may arise between physician and family, concerning the dignity of the dying process or the question whether the sedated patient is suffering or not. Some physicians report they hastened the dying process, in order to relieve the families' suffering. Published by the BMJ Publishing Group Limited.

In the hospital setting, inadequate engagement between healthcare professionals and seriously ill patients and their families regarding end-of-life decisions is common. This problem may lead to medical orders for life-sustaining treatments that are inconsistent with patient preferences. The prevalence of this patient safety problem has not been previously described. Using data from a multi-institutional audit, we quantified the mismatch between patients' and family members' expressed preferences for care and orders for life-sustaining treatments. We recruited seriously ill, elderly medical patients and/or their family members to participate in this audit. We considered it a medical error if a patient preferred not to be resuscitated and there were orders to undergo resuscitation (overtreatment), or if a patient preferred resuscitation (cardiopulmonary resuscitation, CPR) and there were orders not to be resuscitated (undertreatment). From 16 hospitals in Canada, 808 patients and 631 family members were included in this study. When comparing expressed preferences and documented orders for use of CPR, 37% of patients experienced a medical error. Very few patients (8, 2%) expressed a preference for CPR and had CPR withheld in their documented medical orders (Undertreatment). Of patients who preferred not to have CPR, 174 (35%) had orders to receive it (Overtreatment). There was considerable variability in overtreatment rates across sites (range: 14-82%). Patients who were frail were less likely to be overtreated; patients who did not have a participating family member were more likely to be overtreated. Medical errors related to the use of life-sustaining treatments are very common in internal medicine wards. Many patients are at risk of receiving inappropriate end-of-life care.

Setting Occupational Exposure Limits for Genotoxic Substances in the Pharmaceutical Industry.
Lovsin Barle, Ester; Winkler, Gian Christian; Glowienke, Susanne; Elhajouji, Azeddine; Nunic, Jana; Martus, Hans-Joerg
2016-05-01
In the pharmaceutical industry, genotoxic drug substances are developed for life-threatening indications such as cancer. Healthy employees handle these substances during research, development, and manufacturing; therefore, safe handling of genotoxic substances is essential. When an adequate preclinical dataset is available, a risk-based decision related to exposure controls for manufacturing is made following a determination of safe health-based limits, such as an occupational exposure limit (OEL). OELs are calculated for substances based on a threshold dose-response once a threshold is identified. In this review, we present examples of genotoxic mechanisms where thresholds can be demonstrated and OELs can be calculated, including a holistic toxicity assessment. We also propose a novel approach for inhalation Threshold of Toxicological Concern (TTC) limit for genotoxic substances in cases where the database is not adequate to determine a threshold. © The Author 2016.

Self-esteem and life satisfaction are important aspects of positive mental health in young people, and both are socially distributed. However, the majority of evidence is based on socioeconomic characteristics of the family. As children enter adolescence and gain independence, perceptions of their own social position are likely to influence mental health. Using data on 11-year-olds from the UK Millennium Cohort Study, we investigated associations of both family income and young adolescents' perception of their social position with self-esteem and life satisfaction. We hypothesised that there would be differences in the impact of perceived social position on positive mental health when investigating the full scale scoring distribution or the bottom of the distribution. Therefore, we estimated proportional odds for having greater positive mental health (across the distribution of scores) and ORs for poor outcomes (lowest 10% scores). The likelihood of greater self-esteem and life satisfaction increased with income; similarly, the risk of having poor self-esteem and life satisfaction increased as income decreased. Young adolescents who perceived their family as poorer than their friends (instead of about the same) were less likely to have greater self-esteem and life satisfaction and were more likely to have poor outcomes. Young adolescents who perceived their family as richer were more likely to have poor self-esteem, but were not less likely to have greater self-esteem. For life satisfaction, young adolescents who perceived their families as richer were less likely to have greater and more likely to have poor life satisfaction. Policies to redistribute income in families with children are likely to benefit the mental health of young people. However, it is also important to consider the impact of social comparison on young people's mental health as they enter adolescence. Published by the BMJ Publishing Group Limited.

A. Palmgren Revisited: A Basis for Bearing Life Prediction
NASA Technical Reports Server (NTRS)
Zaretsky, Erwin V.
1997-01-01
Bearing technology, as well as the bearing industry, began to develop with the invention of the bicycle in the 1850's. At the same time, high-quality steel was made possible by the Bessemer process. In 1881, H. Hertz published his contact stress analysis. By 1902, R. Stribeck had published his work based on Hertz theory to calculate the maximum load of a radially loaded ball bearing. By 1920, all of the rolling bearing types used today were being manufactured. AISI 52100 bearing steel became the material of choice for these bearings. Beginning in 1918, engineers directed their attention to predicting the lives of these bearings. In 1924, A. Palmgren published a paper outlining his approach to bearing life prediction. This paper was the basis for the Lundberg-Palmgren life theory published in 1947. A critical review of the 1924 Palmgren paper is presented here together with a discussion of its effect on bearing life prediction.
[Book Review] Biology of marine birds

A text devoted to the biology and ecology of marine birds has not been published in the last 15 years. Although a number of more taxa-specific texts have been produced during that period, there has not been a single publication that attempted to review our knowledge of all the major seabird orders since the works of Nelson (1979), Croxall (1987), and Furness and Monaghan (1987). Following the publication of those works, a large and impressive body of literature has been produced. Given the rapid expansion of the field in the last two decades, the time was ripe for production of an extensive compendium on the biology, ecology, and conservation of the world's seabirds.E. A. Schreiber and J. Burger are editors of this CRC publication, Biology of Marine Birds. The book consists of 19 chapters that vary in length from 15 to 51 pages. There are also two extensive appendices: (1) a list of seabird species (restricted to the orders Sphenisciformes, Procellariiformes, Pelecaniformes, and Charadriiformes, the latter limited to Stercorariidae, Laridae, Rhynchopidae, and Alcidae) and their IUCN status, and (2) a very useful table of species-specific life-history traits. The 19 chapters were prepared by 26 authors, among them some of the most respected and published seabird scientists in the world. A brief preface introduces the book, its objective (to provide an examination and summary of the research on seabirds), its audience (researchers, conservationists, managers, and policy-makers), and the taxa covered. The editors coauthored the introductory chapter, Seabirds in the Marine Environment. The authors describe distinctive characteristics of seabird life-histories in comparison to other taxa, hypotheses for why those lifestyles evolved and the potential role of energy limitation in the evolution of seabird life-histories. Along with a discussion of other common seabird traits, such as a propensity for colonial breeding, the authors also suggest directions for future research in seabird ecology.

Chronic thoracic aortic aneurysm (CTAA) affecting the arch or descending aorta is an indolent but life-threatening condition with a rising prevalence as the UK population ages. Treatment may be in the form of open surgical repair (OSR) surgery, endovascular stent grafting (ESG) or best medical therapy (BMT). Currently, there is no consensus on the best management strategy, and no UK-specific economic studies that assess outcomes beyond the chosen procedure, but this is required in the context of greater demand for treatment and limited National Health Service (NHS) resources. This is a prospective, multicentre observational study with statistical and economic modelling of patients with CTAA affecting the arch or descending aorta. We aim to gain an understanding of how treatments are currently chosen, and to determine the clinical effectiveness and cost-effectiveness of the three available treatment strategies (BMT, ESG and OSR). This will be achieved by: (1) following consecutive patients who are referred to the teams collaborating in this proposal and collecting data regarding quality of life (QoL), medical events and hospital stays over a maximum of 5 years; (2) statistical analysis of the comparative effectiveness of the three treatments; and (3) economic modelling of the comparative cost-effectiveness of the three treatments. Primary study outcomes are: aneurysm growth, QoL, freedom from reintervention, freedom from death or permanent neurological injury, incremental cost per quality-adjusted life year gained. The study will generate an evidence base to guide patients and clinicians to determine the indications and timing of treatment, as well as informing healthcare decision-makers about which treatments the NHS should provide. The study has achieved ethical approval and will be disseminated primarily in the form of a Health Technology Assessment monograph at its completion. ISRCTN04044627.

Review and statistical analysis of studies evaluating the effect of surgery on the health-related quality of life of adolescents with adolescent idiopathic scoliosis, using Scoliosis Research Society (SRS) outcomes. Apply published minimum clinical important differences (MCID) values for the SRS22r questionnaire to the literature to identify what areas of health-related quality of life are consistently affected by surgery and whether changes are clinically meaningful. The interpretation of published studies using the SRS outcomes has been limited by the lack of MCID values for the questionnaire domains. The recent publication of these data allows the clinical importance of any changes in these studies to be examined for the first time. A literature search was undertaken to locate suitable studies that were then analyzed. Statistically significant differences from baseline to 2 years postoperatively were ascertained by narratively reporting the analyses within included studies. When possible, clinically significant changes were assessed using 95% confidence intervals for the change in mean domain score. If the lower bound of the confidence intervals for the change exceeded the MCID for that domain, the change was considered clinically significant. The numbers of cohorts available for the different analyses varied (5-16). Eighty-one percent and 94% of included cohorts experienced statistically significant improvements in pain and self-image domains. In terms of clinical significance, it was only self-image that regularly improved by more than MCID, doing so in 4 of 5 included cohorts (80%) compared with 1 of 12 cohorts (8%) for pain. No clinically relevant changes occurred in mental health or activity domains. Evidence suggests that surgery can lead to clinically important improvement in patient self-image. Surgeons and patients should be aware of the limited evidence for improvements in domains other than self-image after surgery. Surgical decision-making will also be influenced by the natural history of adolescent idiopathic scoliosis.

With greater survival rates, patient-reported outcome measures (PROMs) among survivors of ruptured cerebral aneurysm should be an increasing concern among neurointerventionalists. Prior studies were limited in scale and generalizability. Our study aims were to (1) evaluate the validity of cerebral aneurysm PROMs obtained from social media; (2) determine the persistence of PROMs over time; and (3) determine what PROMs still exist in those with no physical impairments. By engaging national brain aneurysm support groups and using an online questionnaire modeled after the generic EQ-5D instrument, we asked respondents to classify their health in five dimensions including mobility, self-care, usual activities, pain/discomfort, and anxiety/depression using a 3-point Likert scale. In 2 months we received 604 responses from 46 states in the USA. Our cohort of ruptured aneurysm respondents reported PROMs similar to previously published series. Over time, headache and anxiety improved while depression, level of exercise, and return to work remained unchanged. We found that memory worsened after 2 years. Among those without any physical impairment, rates of 20.6%, 14.9%, 12.6%, and 23% were seen for significant headaches, significant memory loss, significant depression, and sense of life being negatively affected, respectively. Despite this novel study design, we obtained results comparable to prior studies. These results suggest that many patients with ruptured cerebral aneurysms, regardless of whether they are >2 years after the event and/or free of physical impairment, struggle with a poor quality of life. The latency, scale, and low cost of this study design may accelerate future cerebral aneurysm PROM research. Published by the BMJ Publishing Group Limited.

Objective To determine the availability of data on overall survival and quality of life benefits of cancer drugs approved in Europe. Design Retrospective cohort study. Setting Publicly accessible regulatory and scientific reports on cancer approvals by the European Medicines Agency (EMA) from 2009 to 2013. Main outcome measures Pivotal and postmarketing trials of cancer drugs according to their design features (randomisation, crossover, blinding), comparators, and endpoints. Availability and magnitude of benefit on overall survival or quality of life determined at time of approval and after market entry. Validated European Society for Medical Oncology Magnitude of Clinical Benefit Scale (ESMO-MCBS) used to assess the clinical value of the reported gains in published studies of cancer drugs. Results From 2009 to 2013, the EMA approved the use of 48 cancer drugs for 68 indications. Of these, eight indications (12%) were approved on the basis of a single arm study. At the time of market approval, there was significant prolongation of survival in 24 of the 68 (35%). The magnitude of the benefit on overall survival ranged from 1.0 to 5.8 months (median 2.7 months). At the time of market approval, there was an improvement in quality of life in seven of 68 indications (10%). Out of 44 indications for which there was no evidence of a survival gain at the time of market authorisation, in the subsequent postmarketing period there was evidence for extension of life in three (7%) and reported benefit on quality of life in five (11%). Of the 68 cancer indications with EMA approval, and with a median of 5.4 years' follow-up (minimum 3.3 years, maximum 8.1 years), only 35 (51%) had shown a significant improvement in survival or quality of life, while 33 (49%) remained uncertain. Of 23 indications associated with a survival benefit that could be scored with the ESMO-MCBS tool, the benefit was judged to be clinically meaningful in less than half (11/23, 48%). Conclusions This systematic evaluation of oncology approvals by the EMA in 2009-13 shows that most drugs entered the market without evidence of benefit on survival or quality of life. At a minimum of 3.3 years after market entry, there was still no conclusive evidence that these drugs either extended or improved life for most cancer indications. When there were survival gains over existing treatment options or placebo, they were often marginal. Published by the BMJ Publishing Group Limited.

Due to the increasing number of long-term (≥5 years post diagnosis) colorectal cancer survivors, long-term quality of life of these patients is highly relevant. Several studies have reported a positive association between physical activity and quality of life in colorectal cancer survivors, however, so far no systematic review has been published which focuses on long-term colorectal cancer survivors. A systematic review was conducted using the databases PubMed, Web of Science, PsychINFO, and CINAHL. Studies which investigated associations between physical activity and quality of life in long-term colorectal cancer survivors were included. Ten articles based on seven studies were identified. Long-term colorectal cancer survivors who were physically active reported better quality of life than long-term survivors who were not physically active. Both, moderate to vigorous physical activity and lower levels like light physical activity were associated with higher quality of life. Most studies assessed the association between physical activity and quality of life cross-sectionally but one prospective study which measured physical activity and quality of life at three different points in time also found associations between physical activity and quality of life. The association between physical activity and quality of life seemed to be stronger among women than among men. The findings of this systematic review support an association between physical activity and quality of life in long-term colorectal cancer survivors. However, the evidence is limited as most studies were based on cross-sectional and observational design.
Procedural abortion rights: Ireland and the European Court of Human Rights.
Erdman, Joanna N
2014-11-01
The Irish Protection of Life During Pregnancy Act seeks to clarify the legal ground for abortion in cases of risk to life, and to create procedures to regulate women's access to services under it. This article explores the new law as the outcome of an international human rights litigation strategy premised on state duties to implement abortion laws through clear standards and procedural safeguards. It focuses specifically on the Irish law reform and the jurisprudence of the European Court of Human Rights, including A. B. and C. v. Ireland (2010). The article examines how procedural rights at the international level can engender domestic law reform that limits or expands women's access to lawful abortion services, serving conservative or progressive ends.

We describe the management of a 4-year-old child with acute lymphoblastic leukaemia (ALL) who presented with febrile neutropenia, Cryptosporidium and subsequently developed refeeding syndrome. Febrile neutropenia is common and can be life-threatening and we highlight the identification of well low-risk neutropenic children with resolved febrile illnesses suitable for early discharge. We also discuss the potential management strategies for Cryptosporidium Refeeding syndrome is not common, but should be considered as a cause of acute inpatient deterioration and is a significant risk, with potential morbidity, in children who have undergone a period of catabolism. This article reviews the current literature and provides useful guidance on these issues. Published by the BMJ Publishing Group Limited.

Transfers from hospital or 'hospice palliative care units' to care homes for end-of-life care are an increasingly common part of clinical practice but are a source of anxiety and distress for patients, relatives and healthcare professionals. To understand the experiences of patients discharged to care homes for end-of-life care. Systematic review and narrative synthesis of the UK literature concerning inpatient transfer from a hospital or hospice palliative care unit to a care home for end-of-life care. The published literature is very limited: only three papers and one conference abstract were identified, all of low quality using Gough's weight of evidence assessment. No papers examined transfer from hospital: all were of transfers from hospices and were retrospective case note reviews. Many patients were reported to have been negative or ambivalent about moving and experienced feelings of anxiety or abandonment when transferred. Relatives were often either vehemently opposed or ambivalent. Although some came to accept transfer, others reported the transfer to have seriously affected their loved one's quality of life and that the process of finding a care home had been traumatic. No studies investigated patients' views prospectively, the views of staff or the processes of decision-making. The UK literature is very limited, despite such transfers being an increasingly common part of clinical practice and a source of concern to patients, relatives and staff alike. Further research is urgently needed in this area, especially studies of patients themselves, in order to understand their experiences and views.

The International Children's Palliative Care Network (ICPCN) is a global network of individuals and organizations working together to reach the estimated 21 million children with life-limiting conditions and life-threatening illnesses. The drive to establish the ICPCN was born from the recognition of the gaps in service provision for children's palliative care and the need to collaborate, network, and share resources. Established in 2005 during a meeting in Seoul, South Korea, the ICPCN has developed over the years into an established network with a global membership. The history of the organization is described, including some of the key events since its inception. Working in collaboration with others, ICPCN has five key focus areas: Communication; Advocacy; Research; Education; and Strategic development, and is the only international charity working globally for the rights of children with palliative care needs. Activities in these areas are discussed, along with the inter-connection between the five areas. Without the ICPCN, palliative care for children would not have developed as far as it has over the years and the organization is committed to ongoing work in this area until all children requiring palliative care have access to quality services, wherever they live around the world.

Background/Objectives To validly assess quality-of-care differences among providers, performance measurement programs must reliably identify and exclude patients for whom the quality indicator may not be desirable, including those with limited life expectancy. We developed an algorithm to identify patients with limited life expectancy and examined the impact of limited life expectancy on glycemic control and treatment intensification among diabetic patients. Design We identified diabetic patients with coexisting congestive heart failure, chronic obstructive pulmonary disease, dementia, end-stage liver disease, and/or primary/metastatic cancers with limited life expectancy. To validate our algorithm, we assessed 5-year mortality among patients identified as having limited life expectancy. We compared rates of meeting performance measures for glycemic control between patients with and without limited life expectancy. Among uncontrolled patients, we examined the impact of limited life expectancy on treatment intensification within 90 days. Setting 110 Veterans Administration facilities; October 2006 – September 2007 Participants 888,628 diabetic patients Measurements Hemoglobin A1c (HbA1c) <9%; treatment intensification within 90 days Results 29,016 (3%) patients had limited life expectancy. Adjusting for age, 5-year mortality was 5 times higher among patients with limited life expectancy than those without. Patients with limited life expectancy had poorer glycemic control (77.1% vs. 78.1%) and less frequent treatment intensification (20.9% vs. 28.6%) than patients without, even after controlling for patient-level characteristics (odds ratio [OR]=0.84; 95% confidence interval [CI]=0.81-0.86 and OR=0.71; 95% CI=0.67-0.76, respectively). Conclusion Patients with limited life expectancy were slightly, but significantly less likely than those without to have HbA1c levels controlled and to receive treatment intensification, suggesting that providers treat these patients less aggressively. Quality measurement and performance-based reimbursement systems should acknowledge the different needs of this population. PMID:22260627
[What is an efficient health technology in Spain?].

Despite the growing recognition of the potential applications of cost-effectiveness assessments, a criterion to establish what is an efficient health technology does not exist in Spain. The objective of this work is to describe the limits and the criteria used in Spain to recommend the adoption of health interventions. A review of the economic evaluations of health technologies published in Spain from 1990 to 2001 was conducted. Complete economic assessments in which the cost-effectiveness ratio was expressed as cost per life-year gained (LYG), cost per quality-adjusted-life-year (QALY) or cost per saved live were selected. Those interventions in which the authors established recommendations (adoption or rejection) and the criteria used were analyzed. Twenty (20%) of the 100 complete economic evaluations fulfilled the selection criteria. In16 studies, the results were expressed as cost per LYG, in 6 studies as cost per QALY and in 1 as cost per saved live. A total of 82 health interventions were assessed and some kind of recommendation was established in 44 of them. All technologies with a cost-effectiveness ratio lower than 30,000 euros (5 million pesetas) per LYG were recommended for adoption by the authors. Up to that limit there was no a clear tendency. Although the results must be interpreted with much precaution, given the limitations of the study, the limits of cost-effectiveness presented in this work could be a first reference to which would be an efficient health intervention in Spain.

Previous research has suggested that individuals who identify as being more religious request more aggressive medical treatment at end of life. These requests may generate disagreement over life-sustaining treatment (LST). Outside of anecdotal observation, however, the actual role of religion in conflict over LST has been underexplored. Because ethics committees are often consulted to help mediate these conflicts, the ethics consultation experience provides a unique context in which to investigate this question. The purpose of this paper was to examine the ways religion was present in cases involving conflict around LST. Using medical records from ethics consultation cases for conflict over LST in one large academic medical centre, we found that religion can be central to conflict over LST but was also present in two additional ways through (1) religious coping, including a belief in miracles and support from a higher power, and (2) chaplaincy visits. In-hospital mortality was not different between patients with religiously versus non-religiously centred conflict. In our retrospective cohort study, religion played a variety of roles and did not lead to increased treatment intensity or prolong time to death. Ethics consultants and healthcare professionals involved in these cases should be cognisant of the complex ways that religion can manifest in conflict over LST.

It is unclear whether psychological stress is associated with increased risk of multiple sclerosis (MS). We studied the association between major stressful life events and MS in a nationwide cohort study using death of a child or a spouse or marital dissolution as indicators of severe stress. We created two study cohorts based on all Danish men and women born 1950-1992. One cohort consisted of all persons who became parents between 1968 and 2010, and another cohort consisted of all persons who married between 1968 and 2010. Members of both cohorts were followed for MS between 1982 and 2010 using data from the National Multiple Sclerosis Registry. Associations between major stressful life events and risk of MS were evaluated by means of MS incidence rate ratios (RR) with 95% confidence interval (CI) obtained in Poisson regression analyses. During approximately 30 million person-years of follow-up, bereaved parents experienced no unusual risk of MS compared with parents who did not lose a child (RR=1.12 (95% CI 0.89 to 1.38)). Likewise, neither divorced (RR=0.98 (95% CI 0.89 to 1.06)) nor widowed (RR=0.98 (95% CI 0.71 to 1.32) persons were at any unusual risk of MS compared with married persons of the same sex. Our national cohort study provides little evidence for a causal association between major stressful life events (as exemplified by divorce or the loss of a child or a spouse) and subsequent MS risk.

The burden of ill-health due to inactivity has recently been highlighted. Better studies on environments that support physical activity are called for, including longitudinal studies of environmental interventions. A programme of residential street improvements in the UK (Sustrans 'DIY Streets') allowed a rare opportunity for a prospective, longitudinal study of the effect of such changes on older adults' activities, health and quality of life. Pre-post, cross-sectional surveys were carried out in locations across England, Wales and Scotland; participants were aged 65+ living in intervention or comparison streets. A questionnaire covered health and quality of life, frequency of outdoor trips, time outdoors in different activities and a 38-item scale on neighbourhood open space. A cohort study explored changes in self-report activity and well-being postintervention. Activity levels were also measured by accelerometer and accompanying diary records. The cross-sectional surveys showed outdoor activity predicted by having a clean, nuisance-free local park, attractive, barrier-free routes to it and other natural environments nearby. Being able to park one's car outside the house also predicted time outdoors. The environmental changes had an impact on perceptions of street walkability and safety at night, but not on overall activity levels, health or quality of life. Participants' moderate-to-vigorous activity levels rarely met UK health recommendations. Our study contributes to methodology in a longitudinal, pre-post design and points to factors in the built environment that support active ageing. We include an example of knowledge exchange guidance on age-friendly built environments for policy-makers and planners. Published by the BMJ Publishing Group Limited.

It is not known which of the many asthma-specific quality of life (QoL) questionnaires best capture the lived experience of people with asthma. The objective of this study was to explore patients' views of three commonly used asthma-specific QoL questionnaires. Qualitative study using semistructured interviews. Primary and secondary care in Brighton and Hove, UK. 30 adult people with a physician-diagnosis of asthma who were asked to complete the Juniper Asthma Quality of Life Questionnaire (AQLQ-J), the Sydney Asthma Quality of Life Questionnaire (AQLQ-S) and the Living with Asthma Questionnaire (LWAQ) to elicit their views on the content validity of these. Thematic content analysis revealed a lack of congruence between the concerns of people with asthma and the questionnaire content in terms of missing (eg, allergies) and irrelevant (eg, smoky restaurants) content. The AQLQ-J was perceived as a 'narrow', 'medical' questionnaire focused on symptoms, the environment and functional ability. In contrast, the LWAQ and the AQLQ-S were perceived to be 'non-medical'. The LWAQ was described as a 'test' and as a wide-ranging, embracing and holistic questionnaire. Its strong emotional focus was irritating to some. The AQLQ-S was described as a simple, quick and easy questionnaire, although there was a perception that it was lacking in depth. Patient interviews highlighted strengths and shortcomings in the content validity of these three asthma-specific questionnaires. For patients, the AQLQ-S content seemed to be the most pertinent in its adequacy of coverage of medical, social and emotional aspects of health-related QoL in asthma.

To examine bereaved relatives' experiences from time of diagnosis of incurable cancer until death with specific emphasis on their role in the (end-of-life) decision-making concerning chemotherapy. Qualitative interview study. Hospital-based. In-depth interviews with 15 close relatives of patients who died from non-small cell lung cancer or pancreatic cancer, using a thematic content analysis. All relatives reported that patients' main reason to request chemotherapy was the possibility to prolong life. Relatives reported that patients receiving chemotherapy had more difficulty to accept the incurable nature of their disease than patients who did not. They mostly followed the patients' treatment wish and only infrequently suggested ceasing chemotherapy (because of side effects) despite sometimes believing that this would be a better option. Relatives continuously tried to support the patient in either approaching the death or in attaining hope to continue life satisfactorily. Most relatives considered the chemotherapy period meaningful, since it sparked patients' hope and was what patients wanted. Cessation of chemotherapy caused a relief but coincided with physical deterioration and an increased caregivers' role; many relatives recalled this latter period as more burdensome. Relatives tend to follow patients' wish to continue or cease chemotherapy, without expressing their own feelings, although they were more inclined to opt cessation. They experience a greater caregiver role after cessation and their feelings of responsibility associated with the disease can be exhausting. More attention is needed to reduce relatives' distress at the end of life, also to fully profit from this crucial form of (informal) healthcare. Published by the BMJ Publishing Group Limited.

To present and discuss the views of researchers at an academic palliative care research centre on research encounters with terminally ill patients in the home setting and to generate a list of recommendations for qualitative researchers working in palliative and end-of-life care. Eight researchers took part in a consensus meeting to discuss their experiences of undertaking qualitative interviews. The researchers were of varying backgrounds and all reported having experience in interviewing terminally ill patients, and all but one had experience of interviewing patients in their home environment. The main areas discussed by researchers included: whether participation in end-of-life research unintentionally becomes a therapeutic experience or an ethical concern; power relationships between terminally ill patients and researchers; researcher reflexivity and reciprocity; researchers' training needs. Qualitative methods can complement the home environment; however, it can raise ethical and practical challenges, which can be more acute in the case of research undertaken with palliative and patients at the end-of-life. The ethical and practical challenges researchers face in this context has the potential to place both participant and researcher at risk for their physical and psychological well-being. We present a set of recommendations for researchers to consider prior to embarking on qualitative research in this context and advocate researchers in this field carefully consider the issues presented on a study-by-study basis.

UK policymakers, clinicians and public wish to see improvements in end-of-life care (EoLC). However, healthcare professionals' skills and knowledge to deliver high-quality care are often lacking. Since May 2012, palliative care staff in an inner-city tertiary hospital have run a 2-day Transforming End of Life Care (TEoLC) course to improve EoLC confidence, and competence among hospital and community staff. To evaluate course participants' self-rated confidence, competence and knowledge of EoLC topics. A before-and-after design using self-completion questionnaires, precourse and postcourse. 14 self-assessment questions examined confidence, understanding and knowledge of EoLC topics. Mean change scores and paired t tests were calculated and free-text responses analysed thematically. 236 staff members completed the course between May 2012 and April 2014. 42% worked in hospitals and 55% in the community; the most frequent staff roles were qualified nurses (49%), senior nurses (16%) and general practitioners (15%). All 14 self-assessment topics improved significantly (p<0.001); most improved was 'understanding and implementing Fast Track discharge'. Qualitative data showed increased knowledge and confidence in EoLC, particularly in communication, commitment to team work and holistic care. Overall, 217 (92%) participants would recommend the course and 215 (98%) indicated it would influence their practice. The TEoLC course improved participants' self-rated confidence, competence and knowledge in EoLC. Findings have utility beyond the UK in light of the international policy recommendations to improve the palliative care skills of generalist healthcare providers.

The Belgian model of 'integral' end-of-life care consists of universal access to palliative care (PC) and legally regulated euthanasia. As a first worldwide, the Flemish PC organisation has embedded euthanasia in its practice. However, some critics have declared the Belgian-model concepts of 'integral PC' and 'palliative futility' to fundamentally contradict the essence of PC. This article analyses the various essentialistic arguments for the incompatibility of euthanasia and PC. The empirical evidence from the euthanasia-permissive Benelux countries shows that since legalisation, carefulness (of decision making) at the end of life has improved and there have been no significant adverse 'slippery slope' effects. It is problematic that some critics disregard the empirical evidence as epistemologically irrelevant in a normative ethical debate. Next, rejecting euthanasia because its prevention was a founding principle of PC ignores historical developments. Further, critics' ethical positions depart from the PC tenet of patient centeredness by prioritising caregivers' values over patients' values. Also, many critics' canonical adherence to the WHO definition of PC, which has intention as the ethical criterion is objectionable. A rejection of the Belgian model on doctrinal grounds also has nefarious practical consequences such as the marginalisation of PC in euthanasia-permissive countries, the continuation of clandestine practices and problematic palliative sedation until death. In conclusion, major flaws of essentialistic arguments against the Belgian model include the disregard of empirical evidence, appeals to canonical and questionable definitions, prioritisation of caregiver perspectives over those of patients and rejection of a plurality of respectable views on decision making at the end of life.

Researchers carrying out a rebranding exercise for us in 2006 found that people from Black Asian and other Minority Ethnic (BAME) communities did not respond to their survey. This appeared to support anecdotal evidence from staff suggesting that the number of BAME patients accessing our services did not reflect the real need. To increase access to Hospice Care services for people from BAME communities. From April to July 2007 we used qualitative methods to carry out an exploratory study, to identify barriers to hospice care for patients from BAME communities. Currently we use community development methods to raise awareness of hospice services among BAME communities in Birmingham and Sandwell; while offering training and cultural/spiritual broker services to clinicians increasing their understanding of patients and families from these communities. There was no information about Hospice care services among people from BAME communities. Many people from BAME communities belong to cultural or spiritual groups whose members support each other during times of celebration, illness, death and bereavement. They refer to this support as 'our way of life'. Death, dying, and cancer are taboo subjects. In 2009 we set up the Compassionate Communities Project (CCP) within our Reaching People Programme (RPP) to increase access to our services for people from BAME communities. CCP enables community groups and service providers to work together in end of life. Representatives from BAME communities help train clinicians on supporting people from their communities in end of life. © 2015, Published by the BMJ Publishing Group Limited.

Life cycle water use for electricity generation: a review and harmonization of literature estimates
NASA Astrophysics Data System (ADS)
Meldrum, J.; Nettles-Anderson, S.; Heath, G.; Macknick, J.
2013-03-01
This article provides consolidated estimates of water withdrawal and water consumption for the full life cycle of selected electricity generating technologies, which includes component manufacturing, fuel acquisition, processing, and transport, and power plant operation and decommissioning. Estimates were gathered through a broad search of publicly available sources, screened for quality and relevance, and harmonized for methodological differences. Published estimates vary substantially, due in part to differences in production pathways, in defined boundaries, and in performance parameters. Despite limitations to available data, we find that: water used for cooling of thermoelectric power plants dominates the life cycle water use in most cases; the coal, natural gas, and nuclear fuel cycles require substantial water per megawatt-hour in most cases; and, a substantial proportion of life cycle water use per megawatt-hour is required for the manufacturing and construction of concentrating solar, geothermal, photovoltaic, and wind power facilities. On the basis of the best available evidence for the evaluated technologies, total life cycle water use appears lowest for electricity generated by photovoltaics and wind, and highest for thermoelectric generation technologies. This report provides the foundation for conducting water use impact assessments of the power sector while also identifying gaps in data that could guide future research.
Family food practices: relationships, materiality and the everyday at the end of life.
Ellis, Julie
2018-02-01
This article draws on data from a research project that combined participant observation with in-depth interviews to explore family relationships and experiences of everyday life during life-threatening illness. In it I suggest that death has often been theorised in ways that make its 'mundane' practices less discernible. As a means to foreground the everyday, and to demonstrate its importance to the study of dying, this article explores the (re)negotiation of food and eating in families facing the end of life. Three themes that emerged from the study's broader focus on family life are discussed: 'food talk' and making sense of illness; food, family and identity; and food 'fights'. Together the findings illustrate the material, social and symbolic ways in which food acts relationally in the context of dying, extending conceptual work on materiality in death studies in novel directions. The article also contributes new empirical insights to a limited sociological literature on food, families and terminal illness, building on work that theorises the entanglements of materiality, food, bodies and care. The article concludes by highlighting the analytical value of everyday materialities such as food practices for future research on dying as a relational experience. © 2018 The Author.

The genetic covariance between life cycle stages separated by metamorphosis.
Aguirre, J David; Blows, Mark W; Marshall, Dustin J
2014-08-07
Metamorphosis is common in animals, yet the genetic associations between life cycle stages are poorly understood. Given the radical changes that occur at metamorphosis, selection may differ before and after metamorphosis, and the extent that genetic associations between pre- and post-metamorphic traits constrain evolutionary change is a subject of considerable interest. In some instances, metamorphosis may allow the genetic decoupling of life cycle stages, whereas in others, metamorphosis could allow complementary responses to selection across the life cycle. Using a diallel breeding design, we measured viability at four ontogenetic stages (embryo, larval, juvenile and adult viability), in the ascidian Ciona intestinalis and examined the orientation of additive genetic variation with respect to the metamorphic boundary. We found support for one eigenvector of G: (gobsmax ), which contrasted larval viability against embryo viability and juvenile viability. Target matrix rotation confirmed that while gobsmax shows genetic associations can extend beyond metamorphosis, there is still considerable scope for decoupled phenotypic evolution. Therefore, although genetic associations across metamorphosis could limit that range of phenotypes that are attainable, traits on either side of the metamorphic boundary are capable of some independent evolutionary change in response to the divergent conditions encountered during each life cycle stage. © 2014 The Author(s) Published by the Royal Society.

Investigate the work-life balance of doctors in training in the UK from the perspectives of trainers and trainees. Qualitative semistructured focus groups and interviews with trainees and trainers. Postgraduate medical training in London, Yorkshire and Humber, Kent, Surrey and Sussex, and Wales during the junior doctor contract dispute at the end of 2015. Part of a larger General Medical Council study about the fairness of postgraduate medical training. 96 trainees and 41 trainers. Trainees comprised UK graduates and International Medical Graduates, across all stages of training in 6 specialties (General Practice, Medicine, Obstetrics and Gynaecology, Psychiatry, Radiology, Surgery) and Foundation. Postgraduate training was characterised by work-life imbalance. Long hours at work were typically supplemented with revision and completion of the e-portfolio. Trainees regularly moved workplaces which could disrupt their personal lives and sometimes led to separation from friends and family. This made it challenging to cope with personal pressures, the stresses of which could then impinge on learning and training, while also leaving trainees with a lack of social support outside work to buffer against the considerable stresses of training. Low morale and harm to well-being resulted in some trainees feeling dehumanised. Work-life imbalance was particularly severe for those with children and especially women who faced a lack of less-than-full-time positions and discriminatory attitudes. Female trainees frequently talked about having to choose a specialty they felt was more conducive to a work-life balance such as General Practice. The proposed junior doctor contract was felt to exacerbate existing problems. A lack of work-life balance in postgraduate medical training negatively impacted on trainees' learning and well-being. Women with children were particularly affected, suggesting this group would benefit the greatest from changes to improve the work-life balance of trainees.

End-of-life conversations and care: an asset-based model for community engagement.
Matthiesen, Mary; Froggatt, Katherine; Owen, Elaine; Ashton, John R
2014-09-01
Public awareness work regarding palliative and end-of-life care is increasingly promoted within national strategies for palliative care. Different approaches to undertaking this work are being used, often based upon broader educational principles, but little is known about how to undertake such initiatives in a way that equally engages both the health and social care sector and the local communities. An asset-based community engagement approach has been developed that facilitates community-led awareness initiatives concerning end-of-life conversations and care by identifying and connecting existing skills and expertise. (1) To describe the processes and features of an asset-based community engagement approach that facilitates community-led awareness initiatives with a focus on end-of-life conversations and care; and (2) to identify key community-identified priorities for sustainable community engagement processes. An asset-based model of community engagement specific to end-of-life issues using a four-step process is described (getting started, coming together, action planning and implementation). The use of this approach, in two regional community engagement programmes, based across rural and urban communities in the northwest of England, is described. The assets identified in the facilitated community engagement process encompassed people's talents and skills, community groups and networks, government and non-government agencies, physical and economic assets and community values and stories. Five priority areas were addressed to ensure active community engagement work: information, outreach, education, leadership and sustainability. A facilitated, asset-based approach of community engagement for end-of-life conversations and care can catalyse community-led awareness initiatives. This occurs through the involvement of community and local health and social care organisations as co-creators of this change across multiple sectors in a sustainable way. This approach provides a framework for other communities seeking to engage with public awareness in end-of-life issues. Published by the BMJ Publishing Group Limited.

Inching towards wholeness: C.G. Jung and his relationship to Judaism.
Zemmelman, Steve
2017-04-01
The evolution of Jung's relationship with Judaism is interpreted as reflecting aspects of the individuation journey over the course of a long life. The progress and limitations of his public positions and personal relationships are explored through his published work and correspondence. Perspectives from relational psychoanalysis and Jewish philosophy are used to amplify Jung's understanding of Jewish, and specifically Kabbalistic, text and image. Dimensions of the author's own journey toward greater acceptance of his own Jewish soul is also considered, along with the wider contemporary relevance of these themes. © 2017, The Society of Analytical Psychology.

Breathlessness remains a highly prevalent and distressing symptom for many patients with progressive life-limiting illnesses. Evidence-based interventions for chronic breathlessness are limited, and there is an ongoing need for high-quality research into developing management strategies for optimal palliation of this complex symptom. Previous studies have suggested that selective serotonin reuptake inhibitors such as sertraline may have a role in reducing breathlessness. This paper presents the protocol for a large, adequately powered randomised study evaluating the use of sertraline for chronic breathlessness in people with progressive life-limiting illnesses. A total of 240 participants with modified Medical Research Council Dyspnoea Scale breathlessness of level 2 or higher will be randomised to receive either sertraline or placebo for 28 days in this multisite, double-blind study. The dose will be titrated up every 3 days to a maximum of 100 mg daily. The primary outcome will be to compare the efficacy of sertraline with placebo in relieving the intensity of worst breathlessness as assessed by a 0-100 mm Visual Analogue Scale. A number of other outcome measures and descriptors of breathlessness as well as caregiver assessments will also be recorded to ensure adequate analysis of participant breathlessness and to allow an economic analysis to be performed. Participants will also be given the option of continuing blinded treatment until either study data collection is complete or net benefit ceases. Appropriate statistical analysis of primary and secondary outcomes will be used to describe the wealth of data obtained. Ethics approval was obtained at all participating sites. Results of the study will be submitted for publication in peer-reviewed journals and the key findings presented at national and international conferences. ACTRN12610000464066.

Life zone investigations in Wyoming
Cary, Merritt
1917-01-01
Wyoming is among the foremost of our States in its wealth of natural scenery, culminating in the grandeur of Yellowstone National Park, one of the wonders of the world. In addition to this distinction it posseses vast open plains and lofty mountains whence flow the headwaters of mighty river systems emptying far away to the west into the Pacific Ocean, to the southeast into the Gulf of Mexico, and to the southwest into the Gulf of California. The various slope exposures of its mountain ranges, the fertility of its intervening valleys or basins, and the aridity of its desert spaces present a study of geographic and vertical distribution of wild life that is in many particulars unique.The study of geographic and vertical distribution of life with the governing factors and attendant problems is valuable as a matter of scientific research and in the attainment of practical knowledge. The Biological Survey has been making detailed investigations of the transcontinental life belts, or zones, of North America for some years, and this work has been carried on with special reference to their practical value. It has become increasingly evident that life zones furnish a fairly accurate index to average climatic conditions and, therefore, are useful as marking the limits of agricultural possibilities, so far as these are dependent upon climate. The knowledge thus gained has been published and made available as the investigations have progressed and the life zones have been mapped.1
Mexico's epidemic of violence and its public health significance on average length of life.
Canudas-Romo, Vladimir; Aburto, José Manuel; García-Guerrero, Victor Manuel; Beltrán-Sánchez, Hiram
2017-02-01
A disproportionate number of homicides have caused Mexican life expectancy to stagnate during the new millennium. No efforts currently exist to quantify the harm of violent acts on the lives of the general population. We quantified the impact of perceived vulnerability on life expectancy. Three Mexican national surveys on perceptions of public safety, life tables, and crime and vital statistics (2000-2014) were used. Prevalence rates of vulnerability/safety by age and sex were obtained from surveys at 2 different levels: federal state and home. The Sullivan method was used to estimate life expectancy lived with and without vulnerability for Mexican women and men. Overall life expectancy at age 20 stagnated between 2005 and 2014 for females and males; yet, there was an increase of 40% and 70% in average number of years lived with vulnerability at the state and home levels, respectively. In 2014, female life expectancy at age 20 was 59.5 years (95% CI 59.0 to 60.1); 71% of these years (42.3 years, 41.6 to 43.0) were spent with perceived vulnerability of violence taking place in the state and 26% at the home (15.3 years, 15 to 15.8). For males, life expectancy at age 20 was 54.5 years (53.7 to 55.1); 64% of these years (34.6 years, 34.0 to 35.4) were lived with perceived vulnerability of violence at the state and 20% at the home (11.1 years, 10.8 to 11.5). The number of years lived with perceived vulnerability among Mexicans has increased by 30.5 million person-years over the last 10 years. If perceived vulnerability remains at its 2014 level, the average Mexican adults would be expected to live a large fraction of his/her life with perceived vulnerability of violence. Acts of violence continue to rise in the country and they should be addressed as a major public health issue before they become endemic. Published by the BMJ Publishing Group Limited.

[End-of-life in specialized medical pediatrics department: A French national survey].
Ravanello, Alice; Desguerre, Isabelle; Frache, Sandra; Hubert, Philippe; Orbach, Daniel; Aubry, Régis
2017-03-01
In France, most of children die in the hospital. This national survey aimed to achieve better understanding of end-of life care in specialized medical pediatrics departments for children facing the end-of-life, identify the available resources, put forward the difficulties encountered by professionals and describe end-of-life paths of children who died in these departments. This study is based on a nationwide survey conducted among all existing specialized medical pediatrics departments (onco-haematology, neurology, reanimation) in France in 2015. Among 94 specialized medical pediatrics departments in France, 53 participated in our survey (response rate=56%). At the time of the survey, 13% of inpatients were facing the end-of-life. Regarding training, 13% of departments did not have personnel trained in palliative care and 21% did not set up any professional support. However, when taking care of a child's end of life in 2014, 77% of these departments solicited a regional resource team of pediatric palliative care. This survey helps describe 225 end-of-life paths of children decease of a terminal illness in the specialized pediatrics departments. Seventy-two percent suffered from refractory symptoms before their death, 64% were concerned by a terminal sedation and 75% by a limitation of life-sustaining treatment decision. End-of-life care is a reality for specialized pediatrics departments. The frequency of major and refractory symptoms often requires the completion of sedation. The resources of service are acceptable but some deficiencies have been noted especially concerning training and support for caregivers, adaptation of premises or family support. Copyright © 2017.

Changing the "Normal Range" for Blood Pressure from 140/90 to 130/Any Improves Risk Assessment.
Fulks, Michael; Stout, Robert L; Dolan, Vera F
2015-01-01
Objective .- Redefine the "normal" reference range for blood pressure from <140/90 to one that more effectively identifies individuals with increased mortality risk. Method .- Data from the recently published 2014 CRL blood pressure study was used. It includes 2,472,706 life insurance applicants tested by Clinical Reference Laboratory from 1993 to 2007 with follow-up for vital status using the September 2011 Social Security Death Master File. Various upper limits of blood pressure (BP in mm Hg) were evaluated to determine if any was superior to the current, commonly used limit of 140/90 in identifying individuals with increased mortality risk. Results .- An alternative reference range using a systolic BP (SBP) <130 with any diastolic BP (DBP) included 84% of life insurance applicants. It had a lower mortality rate and narrower range of relative risk than <140/90, including 89% as many applicants but only 68% as many deaths. This pattern of lives and deaths was consistent across age and sex. Conclusion .- Switching to a "normal" reference range of SBP <130 offers superior risk assessment relative to using BP <140/90 while still including a sufficient percentage of the population.
Aquatic concentrations of chemical analytes compared to ecotoxicity estimates.
Kostich, Mitchell S; Flick, Robert W; Batt, Angela L; Mash, Heath E; Boone, J Scott; Furlong, Edward T; Kolpin, Dana W; Glassmeyer, Susan T
2017-02-01
We describe screening level estimates of potential aquatic toxicity posed by 227 chemical analytes that were measured in 25 ambient water samples collected as part of a joint USGS/USEPA drinking water plant study. Measured concentrations were compared to biological effect concentration (EC) estimates, including USEPA aquatic life criteria, effective plasma concentrations of pharmaceuticals, published toxicity data summarized in the USEPA ECOTOX database, and chemical structure-based predictions. Potential dietary exposures were estimated using a generic 3-tiered food web accumulation scenario. For many analytes, few or no measured effect data were found, and for some analytes, reporting limits exceeded EC estimates, limiting the scope of conclusions. Results suggest occasional occurrence above ECs for copper, aluminum, strontium, lead, uranium, and nitrate. Sparse effect data for manganese, antimony, and vanadium suggest that these analytes may occur above ECs, but additional effect data would be desirable to corroborate EC estimates. These conclusions were not affected by bioaccumulation estimates. No organic analyte concentrations were found to exceed EC estimates, but ten analytes had concentrations in excess of 1/10th of their respective EC: triclocarban, norverapamil, progesterone, atrazine, metolachlor, triclosan, para-nonylphenol, ibuprofen, venlafaxine, and amitriptyline, suggesting more detailed characterization of these analytes.

Poverty and child health in the UK: using evidence for action.
Wickham, Sophie; Anwar, Elspeth; Barr, Ben; Law, Catherine; Taylor-Robinson, David
2016-08-01
There are currently high levels of child poverty in the UK, and for the first time in almost two decades child poverty has started to rise in absolute terms. Child poverty is associated with a wide range of health-damaging impacts, negative educational outcomes and adverse long-term social and psychological outcomes. The poor health associated with child poverty limits children's potential and development, leading to poor health and life chances in adulthood. This article outlines some key definitions with regard to child poverty, reviews the links between child poverty and a range of health, developmental, behavioural and social outcomes for children, describes gaps in the evidence base and provides an overview of current policies relevant to child poverty in the UK. Finally, the article outlines how child health professionals can take action by (1) supporting policies to reduce child poverty, (2) providing services that reduce the health consequences of child poverty and (3) measuring and understanding the problem and assessing the impact of action.

Clinical effectiveness in the diagnosis and acute management of pediatric nephrolithiasis.
Van Batavia, Jason P; Tasian, Gregory E
2016-12-01
The incidence of pediatric nephrolithiasis has risen over the past few decades leading to a growing public health burden. Children and adolescents represent a unique patient population secondary to their higher risks from radiation exposure as compared to adults, high risk of recurrence, and longer follow up time given their longer life expectancies. Ultrasound imaging is the first-line modality for diagnosing suspected nephrolithiasis in children. Although data is limited, the best evidence based medicine supports the use of alpha-blockers as first-line MET in children, especially when stones are small and in a more distal ureteral location. Surgical management of pediatric nephrolithiasis is similar to that in adults with ESWL and URS first-line for smaller stones and PCNL reserved for larger renal stone burden. Clinical effectiveness in minimizing risks in children and adolescents with nephrolithiasis centers around ED pathways that limit CT imaging, strict guidance to ALARA principles or use of US during surgical procedures, and education of both patients and families on the risks of repeat ionizing radiation exposures during follow up and acute colic events.

Quality of life in long-term survivors of intensive care.
Buckley, T A; Cheng, A Y; Gomersall, C D
2001-05-01
Traditionally, outcome from intensive care has focused on mortality. The cost of intensive care and the limited resources devoted to patients who have a poor prognosis also raises questions about the utilisation of such resources. There is increasing pressure for outcome evaluation of intensive care to incorporate assessment of long-term survival and the quality of life in survivors. The principal objectives of this article were to examine current methods of assessing quality of life measures in critically ill patients surviving intensive care and to determine the quality of life of these survivors. Direct and computerised search of published research articles. Measurement of quality of life after intensive care is not common practice. There is a lack of consensus concerning appropriate measuring instruments to be used and how best to interpret results. Despite the availability of general outcome tools and disease specific instruments, there is a paucity of studies in the literature which include assessments of quality of life following intensive care unit (ICU) care. Generic health indices suggest that the quality of life in ICU survivors is acceptable though in certain sub-groups, e.g. adult respiratory distress syndrome and sepsis, quality of life may be moderately impaired. ICU survivors appear to suffer less disability than chronic physical disease patients. Assessment of outcome after intensive care should include health related quality of life measurements. A unifying framework is required to enhance communication between clinicians, administrators and investigators of quality of life research and also to enable more rational and effective decision making at the bedside. Patients who survive intensive care appear to enjoy a reasonable standard of quality of life. While their health status may not be as good, subjectively patients find this acceptable.
Measuring double-electron capture with liquid xenon experiments

We investigate the possibilities of observing the decay mode for 124Xe in which two electrons are captured, two neutrinos are emitted, and the final daughter nucleus is in its ground state, using dark matter experiments with liquid xenon. The first upper limit of the decay half-life is calculated to be 1.66 × 1021 years at a 90% confidence level (C.L.) obtained with the published background data from the XENON100 experiment. Employing a known background model from the large underground xenon (LUX) experiment, we predict that the detection of double-electron capture of 124Xe to the ground state of 124Te with LUX will have approximately 115 events, assuming a half-life of 2.9 × 1021 years. We conclude that measuring 124Xe 2ν double-electron capture to the ground state of 124Te can be performed more precisely with the proposed LUX-Zeplin (LZ) experiment.
Recent Observations on the Performance of Hybrid Ceramic Tribo-Contacts

2015-09-01
Hybrid ceramic ball bearings offer great promise in space applications but have not been rapidly adopted by industry perhaps partly due to the relatively low amount of published data on specific in-vacuum performance. Such bearings, having, typically, silicon nitride balls and 440C or high nitrogen steel (e.g. X30) raceways offer the potential for long life and low torque noise due a combination of chemical inertness, high hardness and the extremely smooth surfaces produced in ceramic balls. Though initial benefits were foreseen for high speed applications, the potential for reduced adhesive forces and wear in conditions of marginal lubrication, and for improvements in lubricant lifetime in long life applications limited by oil tribo-degradation render hybrid ceramic bearings more generally attractive.This paper draws together a number of experimental studies carried out at Pin-on-Disc (POD), Spiral Orbit Tribometer (SOT) and bearing-level recently at ESTL.
Adjuvant Whole Brain Radiotherapy: Strong Emotions Decide But Rational Studies Are Needed

Brain metastases are common in cancer patients and cause considerable morbidity and mortality. For patients with limited disease and good performance status, treatment typically involves a combination of focal measures (e.g., surgical resection or radiosurgery) for the radiographically apparent disease, followed by adjuvant whole brain radiotherapy (WBRT) to treat subclinical disease. Because of concerns regarding the toxicity of WBRT, especially neurocognitive deterioration, many have advocated withholding adjuvant WBRT. Recently published studies have shed more light on the efficacy of adjuvant WBRT and the neurocognitive effects of WBRT. However, the inclusion of neurocognitive and quality-of-life data in clinical trials are stillmore » required to better define the role of adjuvant WBRT. Currently, two Phase III trials are underway, one in Europe and one in North America, that will determine the effect of adjuvant WBRT on patients' quality of life, neurocognitive function, and survival.« less
Early Life Metabolism of Bisphenol A: A Systematic Review of the Literature

2014-01-01
When a comprehensive report on BPA was published in 2008, few data were available to assess the extent to which known poor glucuronidation capacity impacts BPA internal dose in infants and young children. In this paper, evidence that has emerged since the 2008 report is summarized, including: 1) human biomarker studies in children aged 0–5 years; 2) animal studies of neonatal toxicokinetics; and 3) physically based pharmacokinetic (PBPK) models. To address limitations in these studies, we recommend more human biomonitoring studies in children aged 0–5 years in which unmetabolized (free) BPA and BPA metabolites are separately quantified and detailed quality-control data are reported, investigation of metabolic differences between humans and animal species used for the study of BPA metabolism, and enzyme ontogeny studies, which along with biomonitoring studies would reduce uncertainty in PBPK models of early-life BPA metabolism.

A large number of end-of-life tires (ELTs) were sampled and classified by type, age and origin to obtain recycled rubber samples representative of the materials placed on the Italian market. The selected recycled tire rubber samples were physically and chemically characterized and a chemometric approach was used to determine correlations. The polycyclic aromatic hydrocarbons (PAHs) content was correlated to the aromaticity index and a model was built to establish the H-Bay aromaticity index (H-Bay) from the PAH concentrations. ELT of different origin and age produced in non-European countries generally had higher PAH content and a higher H-Bay index. H-Bay values of all the samples were lower than the REACH limits and old tires had higher aromatic content than recent ones, possibly due to the replacement of aromatic oils in tire production.

This article intends to summarize the current views of the IQ Consortium Dissolution Working Group, which comprises various industry companies, on the roles of dissolution testing throughout pharmaceutical product development, registration, commercialization, and beyond. Over the past 3 decades, dissolution testing has evolved from a routine and straightforward test as a component of end-product release into a comprehensive set of tools that the developer can deploy at various stages of the product life cycle. The definitions of commonly used dissolution approaches, how they relate to one another and how they may be applied in modern drug development, and life cycle management is described in this article. Specifically, this article discusses the purpose, advantages, and limitations of quality control, biorelevant, and clinically relevant dissolution methods.

An international committee of demographers has created a carefully documented list of worldwide living supercentenarians (> or =110 years old) that has been published by the Los Angeles Gerontology Research Group on its web site and updated on a weekly basis for the past 6 years [see "snapshot" for the year 2003 in the Appendix]. What can be learned by studying this distinguished group of individuals? Also, what are the implications for understanding the fundamental biological limits to human longevity and maximum life span? Our conclusion: Although everyone agrees that average life expectancy has systematically advanced linearly over the last century, it is not realistic to expect that this pace can continue indefinitely. Our data suggest that, without the invention of some new unknown form of medical breakthrough, the Guinness Book of World Records benchmark established by French woman Jeanne Calment of 122 years, set back in 1997, will be exceedingly difficult to break in our lifetime.

Māori regard stories as a preferred method for imparting knowledge through waiata (song), moteatea (poetry), kauwhau (moralistic tale), pakiwaitara (story) and purakau (myths). Storytelling is also an expression of tinorangatiratanga (self-determination); Māori have the right to manage their knowledge, which includes embodiment in forms transcending typical western formulations. Digital storytelling is a process by which 'ordinary people' create short autobiographical videos. It has found application in numerous disciplines including public health and has been used to articulatethe experiences of those often excluded from knowledge production. To explore the use of digital storytelling as a research method for learning about whānau (family) experiences providing end of life care for kaumātua (older people). Eight Māori and their nominated co-creators attended a three-day digital story telling workshop led by co-researchers Shuchi Kothari and Sarina Pearson. They were guided in the creation of first-person digital stories about caring for kaumātua. The videos were shared at a group screening, and participants completed questionnaires about the workshop and their videos. A Kaupapa Māori narrative analysis was applied to their stories to gain new perspectives on Māori end of life caregiving practices. (Kaupapa Maori research privileges Maori worldviews and indigenous knowledge systems.) Digital storytelling is an appropriate method as Māori is an oral/aural society. It allows Māori to share their stories with others, thus promoting community support at the end of life, befitting a public health approach. Digital storytelling can be a useful method for Māori to express their experiences providing end of life caregiving. © 2015, Published by the BMJ Publishing Group Limited.

Employing imaginative rationality: using metaphor when discussing death.
Llewellyn, Rebecca; Jaye, Chrystal; Egan, Richard; Cunningham, Wayne; Young, Jessica; Radue, Peter
2017-03-01
The prevalence of metaphors in medicine is widely acknowledged. In a qualitative study exploring expectations of longevity, we observed repeated recourse to the imaginative rationality provided by metaphors to express perspectives on longevity and death. Bafflement, acceptance, uncertainty and distress were conveyed through metaphors, providing valuable insight into the internal healthcare frameworks of participants. Skilful use of imaginative rationality in the healthcare setting may illuminate the elusive and often eschewed topic of death in a way that fosters clarity and new understandings, and pave the way towards a better life, and death for patients. By becoming aware of the nuances contained within patients'-as well as their own-metaphors, clinicians may enhance patients' overall healthcare experience and avert unintended miscommunication.

Opposed to the being of Henrietta: bioslavery, pop culture and the third life of HeLa cells.
Moore, Marlon Rachquel
2017-03-01
Operating at the intersection of thanatopolitics and African-American cultural studies, this essay argues that the commercial sale of HeLa-themed art and other bioproducts perpetuates the bioslavery of HeLa cells, a circumstance created by legal and medical discourses tracing back to US racial slavery. Racial slavery normalised economic, social and legal inequities that the nation continues to struggle with and, the article posits, laid foundation for the dynamics that currently exist between Henrietta Lacks' genealogical family, the HeLa cell line, and the medical-pharmaceutical establishment. The author turns to fashion ethics discourse and trademark law as potential sites for reparations. Published by the BMJ Publishing Group Limited.

Mining biomedical images towards valuable information retrieval in biomedical and life sciences.
Ahmed, Zeeshan; Zeeshan, Saman; Dandekar, Thomas
2016-01-01
Biomedical images are helpful sources for the scientists and practitioners in drawing significant hypotheses, exemplifying approaches and describing experimental results in published biomedical literature. In last decades, there has been an enormous increase in the amount of heterogeneous biomedical image production and publication, which results in a need for bioimaging platforms for feature extraction and analysis of text and content in biomedical images to take advantage in implementing effective information retrieval systems. In this review, we summarize technologies related to data mining of figures. We describe and compare the potential of different approaches in terms of their developmental aspects, used methodologies, produced results, achieved accuracies and limitations. Our comparative conclusions include current challenges for bioimaging software with selective image mining, embedded text extraction and processing of complex natural language queries. © The Author(s) 2016.

Nanotechnology and its Application in Dentistry
Abiodun-Solanke, IMF; Ajayi, DM; Arigbede, AO
2014-01-01
Nanotechnology influences almost every facet of everyday life from security to medicine. The concept of nanotechnology is that when one goes down to the bottom of things, one can discover unlimited possibilities and potential of the basic particle. In nanotechnology, analysis can be made to the level of manipulating atoms, molecules and chemical bonds between them. The growing interest in the dental applications of nanotechnology is leading to the emergence of a new field called nanodentistry. An electronic database search that included PubMed, MedLine, and Cochrane library was conducted. Key words used in the search are nanotechnology dentistry and applications. Language limitation was set as articles reviewed were only those written and published in English language. We did not search the gray literature. Initially, 52 articles were retrieved from the database, and articles considered were those published from 2008 to 2013. Eight articles that met the selection criteria were eventually selected and reviewed. PMID:25364585
Wealth in Middle and Later Life: Examining the Life Course Timing of Women's Health Limitations.
Wilkinson, Lindsay R; Ferraro, Kenneth F; Mustillo, Sarah A
2018-06-04
Guided by cumulative inequality theory, this study poses two main questions: (a) Does women's poor health compromise household financial assets? (b) If yes, is wealth sensitive to the timing of women's health limitations? In addressing these questions, we consider the effect of health limitations on wealth at older ages, as well as examine how health limitations influence wealth over particular segments of the life course, giving attention to both the onset and duration of health limitations. Using 36 years of data from the National Longitudinal Survey of Mature Women, piecewise growth curve and linear regression models were used to estimate the effects of life course timing and duration of health limitations on household wealth. The findings reveal that women who experienced health limitations accumulated substantially less wealth over time, especially if the health limitations were manifest during childhood or early adulthood. This study identifies how early-life health problems lead to less wealth in later life.

The quality of life of people living with HIV and AIDS (PLWHA) is becoming increasingly important--a fact that is also reflected in extensive research efforts. Owing to the almost complete lack of systematic integration of research findings, it is hardly possible to provide an overview of the current status of research, or to derive valid statements about research results. A literature search regarding the quality of life of PLWHA was performed in two international research databases. After checking their relevance, 852 publications appearing in scientific journals and explicitly measuring the quality of life of PLWHA were categorized on the basis of various study characteristics. The number of publications per year in our study pool has been rising steadily since 1989. Well over 40 established instruments were used to determine the quality of life, most frequently the MOS-HIV, followed by the SF-36. The great majority of the studies are correlation studies. CD4 cells, gender, and age are the most common variables for which correlations with quality of life are reported. Our descriptive review stresses both the increasing significance and the challenges of research into quality of life of PLWHA such as the great variety of instruments used. The limits of this review are discussed and we conclude with the formulation of research desiderata concerning comparative review studies on instruments and systematic reviews of frequent research questions.

Abstract Detection of extant microbial life on Earth and elsewhere in the Solar System requires the ability to identify and enumerate micrometer-scale, essentially featureless cells. On Earth, bacteria are usually enumerated by culture plating or epifluorescence microscopy. Culture plates require long incubation times and can only count culturable strains, and epifluorescence microscopy requires extensive staining and concentration of the sample and instrumentation that is not readily miniaturized for space. Digital holographic microscopy (DHM) represents an alternative technique with no moving parts and higher throughput than traditional microscopy, making it potentially useful in space for detection of extant microorganisms provided that sufficient numbers of cells can be collected. Because sample collection is expected to be the limiting factor for space missions, especially to outer planets, it is important to quantify the limits of detection of any proposed technique for extant life detection. Here we use both laboratory and field samples to measure the limits of detection of an off-axis digital holographic microscope (DHM). A statistical model is used to estimate any instrument's probability of detection at various bacterial concentrations based on the optical performance characteristics of the instrument, as well as estimate the confidence interval of detection. This statistical model agrees well with the limit of detection of 103 cells/mL that was found experimentally with laboratory samples. In environmental samples, active cells were immediately evident at concentrations of 104 cells/mL. Published estimates of cell densities for Enceladus plumes yield up to 104 cells/mL, which are well within the off-axis DHM's limits of detection to confidence intervals greater than or equal to 95%, assuming sufficient sample volumes can be collected. The quantitative phase imaging provided by DHM allowed minerals to be distinguished from cells. Off-axis DHM's ability for rapid low-level bacterial detection and counting shows its viability as a technique for detection of extant microbial life provided that the cells can be captured intact and delivered to the sample chamber in a sufficient volume of liquid for imaging.

Chronic lymphocytic leukemia: economic burden and quality of life: literature review.
Stephens, Jennifer M; Gramegna, Paola; Laskin, Benjamin; Botteman, Marc F; Pashos, Chris L
2005-01-01
The purpose of this review was answer 2 main questions: what is the impact of chronic lymphocytic leukemia (CLL) on the patient's quality of life and how great is the economic burden of this disease on the health care payers and providers. Patients with CLL typically do not receive any treatment soon after the initial diagnosis. Although there is no known cure for CLL yet, when treated, the patients receive aggressive and expensive therapies (eg, chemotherapy or bone marrow transplantation). A rigorous and systematic literature review was performed of English-language articles published in 1990-2002. It was supplemented with additional articles published before 1990 for completeness and additional references to fill the gaps identified in the published medical literature. The literature on the quality of life (QOL) of CLL patients is very limited. We identified only 8 articles, and none of them analyzed the QOL in untreated CLL patients. Because CLL is a disease affecting adults, especially the elderly, all 8 studies measured the QOL in the adult population. QOL difficulties include fear of death and disability, problems gaining employment or health insurance, and fatigue. No specific leukemia or CLL instruments but general QOL instruments (eg, I-HRQL) were identified and some cancer-specific ones (eg, EORTC QLQ-C30, FACT-G, FACT Anemia, FACT-Fatigue). Interestingly, a FACT-Bone Marrow Transplant instrument exists, although we found no study on CLL that used it. Even the literature on the economic burden of CLL is very limited. We identified 13 studies on the cost of CLL: Most of them were cost-identification or cost-comparison studies, and 5 dealt with the cost-effectiveness of medical interventions to treat CLL. Cost drivers identified for CLL were the chemotherapy costs, intravenous immunoglobulin costs, transplantation costs, and costs associated with the differential staining cytotoxicity assay. We identified very few articles on the QOL of CLL patients and therefore cannot draw strong conclusions about the key QOL predictors. Nevertheless, patients with anemia were found to have a better QOL if they had higher hemoglobin counts and good response to erythropoietin treatment. The articles published seem to demonstrate that the older the age of the patient was, the poorer the QOL. The main cost drivers identified for CLL were related to the treatment chosen (eg, chemotherapy, bone marrow transplantation). There are hints that higher costs often result from the delivery of non-optimal therapy that leads to adverse events, infections, and drug resistance. In summary, the impact of this disease on the health care budget of the different health care providers and payers as well as on the patient's QOL is substantially unknown, calling for appropriate economic and QOL studies.

The NASA Lewis Research Center Structures Division is an international leader and pioneer in developing new structural analysis, life prediction, and failure analysis related to rotating machinery and more specifically to hot section components in air-breathing aircraft engines and spacecraft propulsion systems. The research consists of both deterministic and probabilistic methodology. Studies include, but are not limited to, high-cycle and low-cycle fatigue as well as material creep. Studies of structural failure are at both the micro- and macrolevels. Nondestructive evaluation methods related to structural reliability are developed, applied, and evaluated. Materials from which structural components are made, studied, and tested are monolithics and metal-matrix, polymer-matrix, and ceramic-matrix composites. Aeroelastic models are developed and used to determine the cyclic loading and life of fan and turbine blades. Life models are developed and tested for bearings, seals, and other mechanical components, such as magnetic suspensions. Results of these studies are published in NASA technical papers and reference publication as well as in technical society journal articles. The results of the work of the Structures Division and the bibliography of its publications for calendar year 1995 are presented.

Imprinted genes are regulated according to parental origin and can influence embryonic growth and metabolism and confer disease susceptibility. Here, we designed sensitive allele-specific reporters to non-invasively monitor imprinted Cdkn1c expression in mice and showed that expression was modulated by environmental factors encountered in utero. Acute exposure to chromatin-modifying drugs resulted in de-repression of paternally inherited (silent) Cdkn1c alleles in embryos that was temporary and resolved after birth. In contrast, deprivation of maternal dietary protein in utero provoked permanent de-repression of imprinted Cdkn1c expression that was sustained into adulthood and occurred through a folate-dependent mechanism of DNA methylation loss. Given the function of imprinted genes in regulating behavior and metabolic processes in adults, these results establish imprinting deregulation as a credible mechanism linking early-life adversity to later-life outcomes. Furthermore, Cdkn1c-luciferase mice offer non-invasive tools to identify factors that disrupt epigenetic processes and strategies to limit their long-term impact. Copyright © 2017 The Authors.

Life cycle thinking is a good approach to be used for environmental decision-support, although the complexity of the Life Cycle Assessment (LCA) studies sometimes prevents their wide use. The purpose of this paper is to show how LCA methodology can be simplified to be more useful for certain applications. In order to improve waste management in Catalonia (Spain), a Cumulative Energy Demand indicator (LCA-based) has been used to obtain four mathematical models to help the government in the decision of preventing or allowing a specific waste from going out of the borders. The conceptual equations and all the subsequent developments and assumptions made to obtain the simplified models are presented. One of the four models is discussed in detail, presenting the final simplified equation to be subsequently used by the government in decision making. The resulting model has been found to be scientifically robust, simple to implement and, above all, fulfilling its purpose: the limitation of waste transport out of Catalonia unless the waste recovery operations are significantly better and justify this transport.

From the most recent systematic revision of the literature, an orthotopic neobladder would seem to show marginally better health related quality of life (HR-QoL) scores compared with an ileal conduit. The aim of this study was to review all relevant published studies about the comparison between ileal orthotopic neobladder (IONB) and ileal conduit using validated HR-QoL questionnaires. Studies were identified by searching multiple literature databases. Data were synthesized using meta-analytic methods conformed to the PRISMA statement. The literature search identified 10 papers; pooled effect sizes of combined quality of life outcomes for ileal conduit versus IONB showed a significantly better HR-QoL in patients with IONB (Hedges' g = 0.278; p = 0.000);. The present study has an important limitation due to the type of the analyzed comparative studies, all retrospective and not randomized. This meta-analysis of not-randomized, retrospective comparative studies on the impact of ileal conduit versus IONB on HR-QoL showed a significant advantage of IONB subgroups.
Life cycle assessment and grid electricity: what do we know and what can we know?

The generation and distribution of electricity comprises nearly 40% of U.S. CO(2), emissions, as well as large shares of SO(2), NO(x), small particulates, and other toxins. Thus, correctly accounting for these electricity-related environmental releases is of great importance in life cycle assessment of products and processes. Unfortunately, there is no agreed-upon protocol for accounting for the environmental emissions associated with electricity, as well as significant uncertainty in the estimates. Here, we explore the limits of current knowledge about grid electricity in LCA and carbon footprinting for the U.S. electrical grid, and show that differences in standards, protocols, and reporting organizations can lead to important differences in estimates of CO(2) SO(2), and NO(x) emissions factors. We find a considerable divergence in published values for grid emissions factor in the U.S. We discuss the implications of this divergence and list recommendations for a standardized approach to accounting for air pollution emissions in life cycle assessment and policy analyses in a world with incomplete and uncertain information.

Few studies have been published on the reactions of residents to modifications of their residential landscape. We explored residents' experiences of home zone remodelling and construction of a new cycle-walkway in a deprived neighbourhood with a particular focus on aspects of quality of life and physical activity participation. Focus groups (n=5 groups, 21 individuals) were used to investigate residents' perceptions of the effects of neighbourhood change on their lives. Consultation by planners was received positively. Several aspects of the neighbourhood were perceived to have improved, including spatial aesthetics, lighting and streetscape planting. However, influence on physical activity was minimal. Car-focused behaviour and ownership remained dominant, and safety related concerns limited behavioural choices. Residents highlighted many socio-environmental challenges that remained such as sense of neighbourhood safety, poor public transport provision, people's parking behaviour locally, and problem neighbours, and these tended to dominate conversations. Infrastructural intervention may be one important part of multi-layered solutions to improved neighbourhood life. PMID:21145277
Planetarium Inversum -- a space vision for Earth education.
Lotsch, B
2003-01-01
In a planetarium, the visitor is sitting on Earth and looking into an imaginary space. The Planetarium Inversum is the opposite: visitors are sitting in a space station, looking down on Mother Earth. It is a scientifically-based information show with visitors involvement, its elements being partially virtual (Earth in space has to be projected with highest possible resolution) but also containing real structures, such as the visitors' Earth observatory with adjacent biological systems (plant cultures and other ecological life support components). Its main message concerns the limits and the vulnerability of our home planet, its uniqueness, beauty and above all, its irreplaceableness: Earth does not have an emergency exit. The Earth observatory is part of a ring shaped, rotating space station of the type designed by Wernher von Braun decades ago. Visitors are told that gravity is being substituted by centrifugal force. Both types of life support systems are being demonstrated--self regenerative life based ones and technical ones as a backup (solar electric splitting of water and chemical absorption of respiratory CO2). c2003 COSPAR.

Life cycle assessment of thermal waste-to-energy technologies: review and recommendations.
Astrup, Thomas Fruergaard; Tonini, Davide; Turconi, Roberto; Boldrin, Alessio
2015-03-01
Life cycle assessment (LCA) has been used extensively within the recent decade to evaluate the environmental performance of thermal Waste-to-Energy (WtE) technologies: incineration, co-combustion, pyrolysis and gasification. A critical review was carried out involving 250 individual case-studies published in 136 peer-reviewed journal articles within 1995 and 2013. The studies were evaluated with respect to critical aspects such as: (i) goal and scope definitions (e.g. functional units, system boundaries, temporal and geographic scopes), (ii) detailed technology parameters (e.g. related to waste composition, technology, gas cleaning, energy recovery, residue management, and inventory data), and (iii) modeling principles (e.g. energy/mass calculation principles, energy substitution, inclusion of capital goods and uncertainty evaluation). Very few of the published studies provided full and transparent descriptions of all these aspects, in many cases preventing an evaluation of the validity of results, and limiting applicability of data and results in other contexts. The review clearly suggests that the quality of LCA studies of WtE technologies and systems including energy recovery can be significantly improved. Based on the review, a detailed overview of assumptions and modeling choices in existing literature is provided in conjunction with practical recommendations for state-of-the-art LCA of Waste-to-Energy.

To investigate the effect of silicone stent intubation (SI) on the quality of life of patients diagnosed with nasolacrimal duct stenosis and dry eye syndrome. This study is a prospective, interventional case series. Consecutive 30 patients diagnosed with nasolacrimal duct stenosis and reflex tearing due to dry eye syndrome were included. Eligible subjects underwent SI and were asked to complete the Glasgow Benefit Inventory (GBI) questionnaire. Surgical outcomes and GBI scores were investigated 6 months postoperatively. The surgical success rate determined by the patients' subjective symptoms was 76.7% (23/30). Mean total GBI score was +17.19 (95% CI 8.34 to 26.03). The general subscale score was +20.36 (95% CI 10.19 to 30.54), the social support scale score was +21.54 (95% CI 11.37 to 31.71) and the physical health score was -0.56 (95% CI -8.92 to 7.80). SI could be an effective treatment option for reflex tearing in patients diagnosed with dry eye syndrome and nasolacrimal duct stenosis. Published by the BMJ Publishing Group Limited.

Chronic conditions burden patients with illness and treatments. We know little about the disruption of life by the work of dialysis in relation to the resources patients can mobilize, that is, their capacity, to deal with such demands. We sought to determine the disruption of life by dialysis and its relation to patient capacity to cope. We administered a survey to 137 patients on dialysis at an academic medical center. We captured disruption from illness and treatment, and physical, mental, personal, social, financial, and environmental aspects of patient capacity using validated scales. Covariates included number of prescriptions, hours spent on health care, existence of dependents, age, sex, and income level. On average, patients reported levels of capacity and disruption comparable to published levels. In multivariate regression models, limited physical, financial, and mental capacity were significantly associated with greater disruption. Patients in the top quartile of disruption had lower-than-expected physical, financial, and mental capacity. Our sample generally had capacity comparable to other populations and may be able to meet the demands imposed by treatment. Those with reduced physical, financial, and mental capacity reported higher disruption and represent a vulnerable group that may benefit from innovations in minimally disruptive medicine.

Aim To evaluate publications of clinical and life scientists from research institutions in Split, Croatia, and the publication output from government-funded research projects of the University of Split School of Medicine. Methods We analyzed the number of publications from research institutions in Split, Croatia, in the 2000-2006 period, relative impact factors, predominant research fields, output of researchers from the University of Split School of Medicine receiving government research grants, and the average price of published article. Results From 2000 to 2006, clinical and life scientists published 350 articles indexed in Thomson Scientific database Current Contents. The number of articles increased from 30 in 2000 to 76 in 2006, and the average impact factor of journals where these articles were published increased from 2.03 in 2000 to 2.89 in 2006. Twenty percent of articles (72/350) were published in the Croatian Medical Journal. Principal investigators of the 12 research projects receiving government grants published 0 to 8 articles related to the project topic in the 2002-2006 research grant cycle. The research grantees published 78 original research articles, with an average price per article of € 29.210. Conclusion Although the number and impact factor of research articles published by clinical and life scientists from Split, Croatia, is increasing, it is still low when the number of scientists is taken into account. There should be better mechanisms of control and evaluation of research performance of government-funded research projects. PMID:18461671

Advance care planning (ACP) is a process of discussing and recording patients' preferences for future care, aiming to guide healthcare decisions at the end of life (EOL). To explore nuances in the long-term impact of ACP by studying patient and relative experiences. A qualitative follow-up interview study. Interviews were recorded, transcribed and analysed using thematic synthesis. 3 patients with a life-limiting disease (lung or heart disease), affiliated with a major Danish hospital, and 7 relatives were interviewed 1 year after participating in an ACP discussion. The experiences were diverse. Some patients and relatives felt 'relieved', 'more secure' and more in control due to ACP. To some, ACP had led to open communication rather than 'beating around the bush', and to spending more quality time together. However, others perceived ACP as irrelevant. Some stated that the patient's wishes had not been met regardless of ACP. Others felt that EOL questions cannot be realistically considered until 'you're in the middle of it', because many factors are involved. In one case, participating in ACP led to a patient-relative conflict, resulting in EOL issues being 'tucked away'. The study reveals great diversity in patient and relative experiences of ACP. The study challenges previous research which mainly emphasises ACP as a valuable tool to optimise EOL care. This study stresses the importance of awareness of the highly individual nature of preferences and needs of patients and relatives regarding information, involvement and communication about EOL care.

Although morbidity is reduced when sentinel lymph node (SLN) biopsy is performed with dual isotopic and blue dye identification, the effectiveness of adding blue dye to radioisotope remains debated because side effects including anaphylactic reactions. Using data from a prospectively maintained database, 1884 lymph node-negative breast cancer patients who underwent partial mastectomy with SLN mapping by a dual-tracer using patent blue dye (PBD) and radioisotope were retrospectively studied between January 2000 and July 2013. Patients with tumors <3 cm and with >1 node detected by one of the two techniques (N = 1024) were included in this real-life cross-sectional study. Among the 1024 patients, 274 had positive SLN detected by isotopic and/or PBD staining. Only 4 patients having no detectable radioactivity in the axilla had SLN identified only by PBD staining (blue-only) while 26 patients had SLN only identified by isotopic detection (hot-only) illustrating failure rates of 9.5% (26/274) and 1.5% (4/274), respectively. Among these four patients, two had negative lymphoscintigraphy. Therefore, the contribution of PBD to metastatic nodes identification was relevant for only 2/274 patients (0.8%). Three patients (0.3%) had an allergic reaction with PBD, and anaphylactic shock occurred in two cases (0.2%). The added-value of PBD to reduce the false-negative rate of SLN mapping is only limited to the rare cases in which no radioactivity is detectable in the axilla (<1%). When a radioisotope mapping agent is available, the use of PBD should be avoided, because it can induce anaphylaxis. Copyright © 2016 IJS Publishing Group Ltd. Published by Elsevier 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.

As an alternative to the traditional approach to physical exercise, new kinds of organized physical activity have been developed designed to engage large segments of the population. Among these, Zumba fitness is extremely popular, with a growing number of participants. This article aims to summarize and analyze the body of evidence on the effects of Zumba fitness interventions on physical function, fitness, and wellbeing. TYPE: Systematic review. Keyword "Zumba" was identified as term for the literature research in MEDLINE, Scopus, Bandolier, PEDro, and Web of Science. Only studies published in peer-reviewed journals written in English language were considered. Eleven manuscripts were classified as eligible with 586 total participants, ranging in age from 18 to 65 years. After a quality appraisal, we classified 4 studies as high-quality investigations and 7 as low quality. Results were summarized in several domains: "anthropometric parameters and body composition," "hormonal and metabolic profiles," "aerobic and cardiovascular performance," "muscular fitness parameters," and "quality of life, pain score and physical activity questionnaire." Results from this systematic review indicated that Zumba fitness could be considered an effective type of physical activity able to improve aerobic capacity. Small but positive benefits were noted for reducing body weight and other body measurements. Furthermore, other effects, including psychological and social benefits on quality of life, were found after Zumba fitness interventions. Otherwise, limited evidence described positive effects on muscular strength and flexibility. Zumba fitness could be considered an effective type of physical activity able to improve aerobic capacity.

Population ageing is a global challenge and understanding the dynamics of living arrangements in later life and their implications for the design of appropriate housing and long-term care is a critical policy issue. Existing research has focused on the study of transitions into residential care in the UK. This paper investigates transitions into sheltered accommodation among older people in England and Wales between 1993 and 2008. The study uses longitudinal data constructed from pooled observations across waves 2-18 of the British Household Panel Survey (BHPS) data, focusing on individuals aged 65 and over who lived in private housing at baseline and who were observed for two consecutive time points. A discrete-time logistic regression model was used to examine the association of transitioning into sheltered accommodation with a range of demographic, health and socioeconomic predictors. Demographic (age, region), socioeconomic factors (housing tenure, having a washing machine) and contact with health professionals (number of visits to the general practitioner, start in use of health visitor) were significant determinants of an older person's move into sheltered accommodation. Transitions into sheltered accommodation are associated with a range of demographic and socioeconomic characteristics as well as service use but not with health. Such results indicate that this type of housing option may be accessible by individuals with relatively good health, but may be limited to those who are referred by gatekeepers. Policymakers could consider making such housing option available to everyone, as well as providing incentives for building lifecourse-sensitive housing in the future.

Many patients throughout the world consult homeopathic medical doctors. Using a similar methodology as in a first survey published in 2002 a second survey was done including 919 adults receiving homeopathic treatment in six European countries and Brazil aimed to look at who are they, their reasons for consultations and expectations and satisfaction with homeopathy prescribed by a homeopathic doctor after a follow-up time of six months. An initial questionnaire included demographic information and questions for assessing health-related Quality of Life (QoL). A follow-up questionnaire collected data on changes in QoL. 77% patients had initially used conventional treatments and 23% other non-conventional treatments. Satisfaction of patients with the medical homeopathic consultation is high. The difference between the final QoL scores after six months and the baseline are positive. Reported differences between baseline and final index range from 3.87 to 10.41 depending on diagnosis. Taking 7% as a reference value for 'minimal clinically significant difference', this is reached for 3 of 8 conditions. Changes in complaint limitations visual scales are positive. Conclusions on clinical impact must be cautious. 6% of the patients experienced side-effects which they attributed to homeopathic treatment. 7.8% of the patients reported significant aggravation at the beginning of the homeopathic treatment and 26.2% slight aggravation of symptoms. The satisfaction of patients using a medical homeopathic approach is linked to the perceived competence of the doctor homeopath, the perceived improvement of the main complaints limitations and the time dedicated to them by the doctor.

: This one-hour symposium considers Milford Care Centre's Compassionate Communities Good Neighbour Partnership and it's evaluation by an international team, led by Maynooth University and funded by the All Ireland Institute of Hospice and Palliative Care, The Irish Cancer Society, The Irish Hospice Foundation and Milford Care Centre. The symposium will be divided into three sections: 1. The Good Neighbour Partnership: Why do we need it? In this section we will describe the findings from a recent scoping study to determine the social and practical needs of community dwelling adults (and their families) living with advanced life limiting illness at home. We will consider the rationale for specialist palliative care services, working with community groups, to lead the development of a volunteer-based social model of care to address unmet need. 2. The Good Neighbour Partnership: How do we recruit and train volunteers? We will share our process and experience of recruiting and training 15 Compassionate Communities Volunteers to assess unmet social and practical need, and to mobile the person's circle of community to meet those needs. An understanding of the motivating factors of volunteers will be shared. 3. The Good Neighbour Partnership: How on earth are we going to evaluate it? Here we describe the INSPIRE study - Investigating Social and Practical Supports at the End of life. An exploratory delayed intervention randomised controlled trial (framed by the MRC Framework for Complex Interventions) to assess the feasibility, acceptability and potential effectiveness of the Good Neighbour Partnership. © 2015, Published by the BMJ Publishing Group Limited.

social support has demonstrated cross-sectional associations with greater cognitive function and a protective effect against cognitive decline in older adults, but exploration of its temporal role in cognitive ageing from mid-life to older adulthood has been limited. We aimed to quantify the associations of social support, assessed at mid-life, with cognitive function in mid-life and with cognitive decline into late life among African Americans and Caucasians. data from the community-based, prospective Atherosclerosis Risk in Communities (ARIC) cohort of 15,792 biracial participants were examined for baseline and longitudinal associations of mid-life social support with global cognition at mid-life and with 20-year change in global cognition, respectively, stratified by race. Interactions with sociodemographic and cardiometabolic covariates were additionally explored within each race group. Social support was ascertained using two metrics: interpersonal support and social network. interpersonal support was directly associated with greater global cognition at baseline in both race groups. Social network was directly associated with greater global cognition at baseline among Caucasians and African American females, but it was not significantly associated with global cognition in African American males. Neither mid-life social support measure was associated with 20-year change in global cognition. higher levels of social support were moderately associated with greater multi-dimensional cognitive function at mid-life, but mid-life social support was not associated with temporal change in global cognitive function over 20 years into late life. Prospective studies with time-dependent measures of social support and cognition are needed to better understand the role of social engagement in ageing-related cognitive functioning. © The Author 2016.

Research was conducted, within the framework of the International Family Quality of Life Project, on the quality of life of families with a member who has a disability. We concentrated on the nine specific domains that the family life measure used, and recorded data from five of its six measurement dimensions: Importance, Opportunities, Initiative, Attainment and Satisfaction. The sample consisted of 20 families from Slovenia with children who have intellectual or developmental disabilities. The data were collected using the Family Quality of Life Survey-2006. Except for Community Interaction, the other domains (Health, Financial Well-Being, Family Relations, Support from Others, Support Services, Influence of Values, Careers, Leisure and Recreation) show statistically significant differences among the five dimensions measured. Importance was rated highest, and Attainment and Opportunities were rated lowest, while Initiative and Satisfaction were evaluated lower than Importance but higher than Attainment and Opportunities. Among the domains of family life, Family Relations was evaluated the highest from the perspective of all five dimensions. The family members rated Importance high for all of the quality of family life domains, but it appears from the lower Opportunities scores that their opportunities are limited; this may result in fewer possibilities for attaining a better quality of life. The results of our research are useful to Slovene researchers who work in the areas of special pedagogy and rehabilitation, politicians, non-governmental organisations and social services. The quality of life of families with children with disabilities, their empowerment and their inclusion into community life should be significantly enhanced when consideration is given to all the family members' support and service needs. © 2011 The Authors.

Impact of Treatment Subsidies and Cash Payouts on Treatment Choices at the End of Life.
Finkelstein, Eric; Malhotra, Chetna; Chay, Junxing; Ozdemir, Semra; Chopra, Akhil; Kanesvaran, Ravindran
To examine the extent to which financial assistance, in the form of subsidies for life-extending treatments (LETs) or cash payouts, distorts the demand for end-of-life treatments. A discrete choice experiment was administered to 290 patients with cancer in Singapore to elicit preferences for LETs and only palliative care (PC). Responses were fitted to a latent class conditional logistic regression model. We also quantified patients' willingness to pay to avoid and willingness to accept a less effective LET or PC-only. We then simulated the effects of various LET subsidy and cash payout policies on treatment choices. We identified three classes of patients according to their preferences. The first class (26.1% of the sample) had a strong preference for PC and were willing to give up life expectancy gains and even pay for receiving only PC. The second class (29.8% of the sample) had a strong preference for LETs and preferred to extend life regardless of cost or quality of life. The final class (44.1% of the sample) preferred LETs to PC, but actively traded off costs and length and quality of life when making end-of-life treatment choices. Policy simulations showed that LET subsidies increase demand for LETs at the expense of demand for PC, but an equivalent cash payout was not shown to distort demand. Patients with cancer have heterogeneous end-of-life preferences. LET subsidies and cash payouts have differing effects on the use of LETs. Policymakers should be mindful of these differences when designing health care financing schemes for patients with life-limiting illnesses. Copyright © 2016. Published by Elsevier Inc.
Life-history variation of a neotropical thrush challenges food limitation theory
Ferretti, V.; Llambias, P.E.; Martin, T.E.
2005-01-01
Since David Lack first proposed that birds rear as many young as they can nourish, food limitation has been accepted as the primary explanation for variation in clutch size and other life-history traits in birds. The importance of food limitation in life-history variation, however, was recently questioned on theoretical grounds. Here, we show that clutch size differences between two populations of a neotropical thrush were contrary to expectations under Lack's food limitation hypothesis. Larger clutch sizes were found in a population with higher nestling starvation rate (i.e. greater food limitation). We experimentally equalized clutches between populations to verify this difference in food limitation. Our experiment confirmed greater food limitation in the population with larger mean clutch size. In addition, incubation bout length and nestling growth rate were also contrary to predictions of food limitation theory. Our results demonstrate the inability of food limitation to explain differences in several life-history traits: clutch size, incubation behaviour, parental feeding rate and nestling growth rate. These life-history traits were better explained by inter-population differences in nest predation rates. Food limitation may be less important to life history evolution in birds than suggested by traditional theory. ?? 2005 The Royal Society.

To systematically review the published evidence on the prevalence and economic and humanistic burden of astigmatism in cataract patients. For this systematic literature review, the Medline, PubMed, Embase, and Cochrane databases were searched from 1996 to September 2015 for available scientific literature that met the inclusion criteria. Studies published in the English language reporting prevalence and humanistic and economic burden in patients diagnosed with cataract and astigmatism were included. Of 3,649 papers reviewed, 31 studies from 32 publications met the inclusion criteria of this review. Preexisting astigmatism ≥1 D was present in up to 47% of cataract eyes. The cost burden of residual uncorrected astigmatism after cataract surgery was driven by the cost of spectacles, which was estimated to range from $2,151 to $3,440 in the US and $1,786 to $4,629 in Europe over a lifetime. In cataract patients, both preexisting and postoperative residual astigmatism were associated with poor vision-related patient satisfaction and quality of life, as well as higher spectacle burden. Astigmatism correction during cataract surgery appears to improve visual outcomes and results in overall lifetime cost savings compared to astigmatism correction with postoperative vision correction. There is a high prevalence of preexisting astigmatism in cataract patients. Although published data are limited, both preoperative astigmatism and postoperative residual astigmatism affect visual function and vision-related quality of life, resulting in increased humanistic burden. Suboptimal correction of astigmatism during cataract surgery drives the continuous need for vision correction with spectacles in the postoperative period. Patients must bear the out-of-pocket expenses, since payers often do not reimburse the cost of spectacles. Greater access to astigmatism correction during cataract surgery could improve visual outcomes and quality of life in patients. More research is required to gain a better understanding of the disease burden of astigmatism in cataract patients.

To review systematically the evidence of age-related macular degeneration (AMD) affecting real-world visual ability and quality of life (QoL). To explore trends in specific topics within this body of the literature. Systematic review. A systematic literature search was carried out using MEDLINE, EMBASE, CINAHL, PsycINFO, PsychARTICLES and Health and Psychosocial Instruments for articles published up to January 2015 for studies including people diagnosed with AMD, assessing real-world visual ability or QoL as an outcome. Two researchers screened studies for eligibility. Details of eligible studies including study design, characteristics of study population and outcomes measured were recorded in a data extraction table. All included studies underwent quality appraisal using the Mixed Methods Appraisal Tool 2011 Version (MMAT). From 5284 studies, 123 were eligible for inclusion. A range of approaches were identified, including performance-based methods, quantitative and qualitative patient-reported outcome measures (PROMs). AMD negatively affects tasks including mobility, face recognition, perception of scenes, computer use, meal preparation, shopping, cleaning, watching TV, reading, driving and, in some cases, self-care. There is evidence for higher rates of depression among people with AMD than among community dwelling elderly. A number of adaptation strategies have been associated with AMD of varying duration. Much of the research fails to report the type of AMD studied (59% of included studies) or the duration of disease in participants (74%). Of those that do report type studied, the breakdown is as follows: wet AMD 20%, dry AMD 4% and both types 17%. There are many publications highlighting the negative effects of AMD in various domains of life. Future research should focus on delivering some of this research knowledge into patient management and clinical trials and differentiating between the types of AMD.

The critical care context presents important opportunities for nurses to deliver skilled, comprehensive care to patients at the end of life and their families. Limited research has identified the actual end-of-life care practices of critical care nurses. To identify the end-of-life care practices of critical care nurses. A national cross-sectional online survey. The survey was distributed to members of an Australian critical care nursing association and 392 critical care nurses (response rate 25%) completed the survey. Exploratory factor analysis using principal axis factoring with oblique rotation was undertaken on survey responses to identify the domains of end-of-life care practice. Descriptive statistics were calculated for individual survey items. Exploratory factor analysis identified six domains of end-of-life care practice: information sharing, environmental modification, emotional support, patient and family centred decision-making, symptom management and spiritual support. Descriptive statistics identified a high level of engagement in information sharing and environmental modification practices and less frequent engagement in items from the emotional support and symptom management practice areas. The findings of this study identified domains of end-of-life care practice, and critical care nurse engagement in these practices. The findings highlight future training and practice development opportunities, including the need for experiential learning targeting the emotional support practice domain. Further research is needed to enhance knowledge of symptom management practices during the provision of end-of-life care to inform and improve practice in this area.

Socioeconomic differences in screening have been well documented in upper-income countries; however, few studies have examined socioeconomic status (SES) over the life-course in relation to cancer screening in lower-income and middle-income countries. Here, we examine individual, parental and life-course SES differences in breast and cervical cancer screening among women in India, China, Mexico, Russia and South Africa. Data from the WHO's Study on Global Ageing and Adult Health (SAGE) 2007-2008 data were used for survey-weighted multivariable regression analysis. We examined the association between individual, parental and life-course SES in relation to breast and cervical cancer screening using education-based and employment-based measures of SES. 22 283 women aged 18-65 years, recruited from China, India, Mexico, Russia and South Africa. Having a college degree (OR 4.18; 95% CI 2.36 to 7.40) increased the odds of breast cancer screening compared with no formal education. Women with higher parental SES were almost 10 times more likely to receive breast cancer screening (OR 9.84; 95% CI 1.75 to 55.5) compared with women with low parental SES. Stable higher life-course (OR 3.07; 95% CI 1.96 to 4.79) increased breast cancer screening by threefold and increased cervical cancer screening by more than fourfold (OR 4.35; 95% CI 2.94 to 6.45); however, declining life-course SES was associated with reduced breast cancer screening (OR 0.26; 95% CI 0.08 to 0.79) compared to low life-course SES. Higher individual, parental and life-course SES was positively associated with breast and cervical cancer screening, although education-based SES measures were stronger predictors of screening compared with employment-based measures. Improving knowledge of the benefits of cancer screening and integrating cancer screening into routine healthcare practice for low SES women are actionable strategies that may significantly improve screening rates in low-income and middle-income countries.

Effects of cryptic mortality and the hidden costs of using length limits in fishery management
Coggins, L.G.; Catalano, M.J.; Allen, M.S.; Pine, William E.; Walters, C.J.
2007-01-01
Fishery collapses cause substantial economic and ecological harm, but common management actions often fail to prevent overfishing. Minimum length limits are perhaps the most common fishing regulation used in both commercial and recreational fisheries, but their conservation benefits can be influenced by discard mortality of fish caught and released below the legal length. We constructed a computer model to evaluate how discard mortality could influence the conservation utility of minimum length regulations. We evaluated policy performance across two disparate fish life-history types: short-lived high-productivity (SLHP) and long-lived low-productivity (LLLP) species. For the life-history types, fishing mortality rates and minimum length limits that we examined, length limits alone generally failed to achieve sustainability when discard mortality rate exceeded about 0.2 for SLHP species and 0.05 for LLLP species. At these levels of discard mortality, reductions in overall fishing mortality (e.g. lower fishing effort) were required to prevent recruitment overfishing if fishing mortality was high. Similarly, relatively low discard mortality rates (>0.05) rendered maximum yield unobtainable and caused a substantial shift in the shape of the yield response surfaces. An analysis of fishery efficiency showed that length limits caused the simulated fisheries to be much less efficient, potentially exposing the target species and ecosystem to increased negative effects of the fishing process. Our findings suggest that for overexploited fisheries with moderate-to-high discard mortality rates, reductions in fishing mortality will be required to meet management goals. Resource managers should carefully consider impacts of cryptic mortality sources (e.g. discard mortality) on fishery sustainability, especially in recreational fisheries where release rates are high and effort is increasing in many areas of the world. ?? 2007 Blackwell Publishing Ltd.

Living with food allergies affects quality of life (QOL) and may be particularly problematic for teenagers. To develop a validated food allergy QOL assessment tool for US adolescents (FAQL-teen). Initial items were developed through expert opinion, literature review, and adolescent focus groups, resulting in an 88-question impact assessment questionnaire. This questionnaire was completed by 52 adolescents for effect scoring; final instrument questions were determined through analysis of effect scores. The final 17-item instrument was completed by 203 participants aged 13 to 19 years via an Internet link on the Food Allergy & Anaphylaxis Network Web site and via paper surveys distributed at a Food Allergy & Anaphylaxis Network conference. Items were scored on a 7-point Likert scale: 0 corresponded to "not troubled/limited," 3 to "moderately troubled/limited," and 6 to "extremely troubled/limited." Areas most troubling included limitations on social activities (score, 2.7), not being able to eat what others were eating (score, 2.7), and limited choice of restaurants (score, 3.9). Instrument validation steps showed strong internal validity (Cronbach α = .9). The instrument discriminated by disease severity: adolescents with a history of anaphylaxis had significantly lower QOL (higher scores) than did those without a history of anaphylaxis (P = .003). While developing a food allergy QOL assessment tool for US adolescents (FAQL-teen), we identified multiple social and emotional concerns that could be targeted for adolescent counseling. This instrument is internally valid and has the ability to discriminate, making it a useful tool in adolescent food allergy studies. Copyright © 2010 American College of Allergy, Asthma & Immunology.

Thermal tolerance has been hypothesized to result from a mismatch between oxygen supply and demand. However, the generality of this hypothesis has been challenged by studies on various animal groups, including air-breathing adult insects. Recently, comparisons across taxa have suggested that differences in gas exchange mechanisms could reconcile the discrepancies found in previous studies. Here, we test this suggestion by comparing the behaviour of related insect taxa with different gas exchange mechanisms, with and without access to air. We demonstrate oxygen-limited thermal tolerance in air-breathing adults of the plastron-exchanging water bug Aphelocheirus aestivalis. Ilyocoris cimicoides, a related, bimodal gas exchanger, did not exhibit such oxygen-limited thermal tolerance and relied increasingly on aerial gas exchange with warming. Intriguingly, however, when denied access to air, oxygen-limited thermal tolerance could also be induced in this species. Patterns in oxygen-limited thermal tolerance were found to be consistent across life-history stages in these insects, with nymphs employing the same gas exchange mechanisms as adults. These results advance our understanding of oxygen limitation at high temperatures; differences in the degree of respiratory control appear to modulate the importance of oxygen in setting tolerance limits. © 2015.

Background The Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification of severity of chronic obstructive pulmonary disease (COPD) is based solely on obstruction and does not capture physical functioning. The hypothesis that the Medical Research Council (MRC) dyspnoea scale would correlate better with quality of life than the level of airflow limitation was examined. Aim To study the associations between quality of life in smokers and limitations in physical functioning (MRC dyspnoea scale) and, quality of life and airflow limitation (GOLD COPD stages). Design Cross-sectional study. Setting The city of IJsselstein, a small town in the centre of The Netherlands. Method Male smokers aged 40–65 years without a prior diagnosis of COPD and enlisted with a general practice, participated in this study. Quality of life was assessed by means of a generic (SF–36) and a disease-specific, questionnaire (QOLRIQ). Results A total of 395 subjects (mean age 55.4 years, pack years 27.1) performed adequate spirometry and completed the questionnaires. Limitations of physical functioning according to the MRC dyspnoea scale were found in 25.1 % (99/395) of the participants and airflow limitation in 40.2% (159/395). The correlations of limitations of physical functioning with all quality-of-life components were stronger than the correlations of all quality-of-life subscales with the severity of airflow limitation. Conclusion In middle-aged smokers the correlation of limitations of physical functioning (MRC dyspnoea scale) with quality of life was stronger than the correlation of the severity of airflow limitation with quality of life. Future staging systems of severity of COPD should capture this and not rely on forced expiratory volume in one second (FEV1) alone. PMID:17550673

Research on the health-enhancing effects of later life activities gives limited attention to the age-segregated nature of many organizations; such consideration draws into focus identity processes contributing to these benefits. Studies also focus more on social than on educational organizations. We address these limitations by examining older adults' identity work within the Osher Lifelong Learning Institute (OLLI), a not-for-credit later life educational organization. We use qualitative data from three sources: interviews with OLLI participants and staff (n = 32); observations at OLLI courses, events, and two regional conferences (118 hours); and content analysis of program materials. Data analyses followed a grounded theory approach. Analyses revealed identity work allowing members to view themselves as "lifelong learners." This work involved four processes: (a) framing as a college experience, (b) distancing from nonacademic pursuits, (c) embracing the mature love of learning, and (d) (re)casting themselves as lifelong students. Our study contributes to research on the benefits of later life activity by illuminating identity work processes operating within an age-segregated educational organization. These processes allow members to positively frame themselves as older adults; however, they not only reinforce stereotypes of younger and older adults but also devalue older adults unable to participate or uninterested in lifelong learning programs. © The Author(s) 2015.

The aim of this study was to investigate patients' and families' perspectives of safety and quality in the setting of a life-limiting illness. Data reported here were generated from a qualitative study using video-reflexive ethnographic methodology. Data were collected over 18 months and generated through participant observation, shadowing of clinicians, field-interviews and semi-structured interviews with patients and families. The study was conducted at two hospital sites in Sydney, Australia and in patients' homes. Patients with an advanced life-limiting illness (n = 29) ranging in age between 27 and 89 years and family members (n = 5) participated in the study. Patient safety remains important to dying patients and families. For dying people, iatrogenic harm is not regarded as 'one off' incidents. Rather, harm is experienced as a result of an unfolding series of negative events. Critically, iatrogenic harm is emotional, social and spiritual and not solely technical-clinical misadventure and is inextricably linked with feeling unsafe. Thus, patient safety extends beyond narrowly defined technical-clinical parameters to include interpersonal safety. Current approaches to patient safety do not address fully the needs of dying patients and their families. Patients and their families regard poor communication with and by health professionals to be harmful in and of itself. © The Author 2015.

To evaluate whether accredited hospitals maintain quality and patient safety standards over the accreditation cycle by testing a life cycle explanation of accreditation on quality measures. Four distinct phases of the accreditation life cycle were defined based on the Joint Commission International process. Predictions concerning the time series trend of compliance during each phase were specified and tested. Interrupted time series (ITS) regression analysis of 23 quality and accreditation compliance measures. A 150-bed multispecialty hospital in Abu Dhabi, UAE. Each month (over 48 months) a simple random sample of 24% of patient records was audited, resulting in 276,000 observations collected from 12,000 patient records, drawn from a population of 50,000. The impact of hospital accreditation on the 23 quality measures was observed for 48 months, 1 year preaccreditation (2009) and 3-year postaccreditation (2010-2012). The Life Cycle Model was evaluated by aggregating the data for 23 quality measures to produce a composite score (YC) and fitting an ITS regression equation to the unweighted monthly mean of the series. The four phases of the life cycle are as follows: the initiation phase, the presurvey phase, the postaccreditation slump phase and the stagnation phase. The Life Cycle Model explains 87% of the variation in quality compliance measures (R(2)=0.87). The ITS model not only contains three significant variables (β1, β2 and β3) (p≤0.001), but also the size of the coefficients indicates that the effects of these variables are substantial (β1=2.19, β2=-3.95 (95% CI -6.39 to -1.51) and β3=-2.16 (95% CI -2.52 to -1.80). Although there was a reduction in compliance immediately after the accreditation survey, the lack of subsequent fading in quality performance should be a reassurance to researchers, managers, clinicians and accreditors.

The neighbourhood environment can assist the adoption and maintenance of an active lifestyle and affect the physical and mental well-being of older adults. The psychosocial and behavioural mechanisms through which the environment may affect physical and mental well-being are currently poorly understood. This observational study aims to examine associations between the physical and social neighbourhood environments, physical activity, quality of life and depressive symptoms in Chinese Hong Kong older adults. An observational study of the associations of measures of the physical and social neighbourhood environment, and psychosocial factors, with physical activity, quality of life and depressive symptoms in 900 Hong Kong older adults aged 65+ years is being conducted in 2012-2016. The study involves two assessments taken 6 months apart. Neighbourhood walkability and access to destinations are objectively measured using Geographic Information Systems and environmental audits. Demographics, socioeconomic status, walking for different purposes, perceived neighbourhood and home environments, psychosocial factors, health status, social networks, depressive symptoms and quality of life are being assessed using validated interviewer-administered self-report measures and medical records. Physical functionality is being assessed using the Short Physical Performance Battery. Physical activity and sedentary behaviours are also being objectively measured in approximately 45% of participants using accelerometers over a week. Physical activity, sedentary behaviours, quality of life and depressive symptoms are being assessed twice (6 months apart) to examine seasonality effects on behaviours and their associations with quality of life and depressive symptoms. The study received ethical approval from the University of Hong Kong Human Research Ethics Committee for Non-Clinical Faculties (EA270211) and the Department of Health (Hong Kong SAR). Data are stored in a password-protected secure database for 10 years, accessible only to the named researchers. Findings will be submitted for publication in peer-reviewed journals.

Current coverage of palliative care services in sub-Saharan Africa (SSA) remains woefully inadequate, but harnessing mHealth could be one approach to facilitate greater service coverage and engagement with patients with life-limiting progressive disease. A systematic literature review to identify the development and use of mHealth in palliative care services in SSA. 13 electronic databases from 1990 to 2015 were searched alongside the manual searching of journals and citation searching of included article reference lists. Articles were assessed against inclusion and exclusion criteria and study details extracted and tabulated by two researchers. Studies were plotted against a modified WHO mHealth and ICT framework to classify how they are targeting health system strengthening. Of the 1110 articles identified, 5 met the inclusion criteria, describing mHealth use in Nigeria, Uganda, Kenya and Malawi. Descriptive analysis has shown that existing mHealth interventions for palliative care services in SSA are limited in number and are being developed for use at the palliative treatment, guidance and coordination stage of care provision. Levels of detail about the development and structure of interventions are low. mHealth interventions for palliative care in SSA are limited. This is an opportune time to explore how evidence-based mHealth interventions could form part of the evolving palliative care services in the region. Published by the BMJ Publishing Group Limited.

In the Eplerenone in Mild Patients Hospitalization and Survival Study in Heart Failure (EMPHASIS-HF), aldosterone blockade with eplerenone decreased mortality and hospitalisation in patients with mild symptoms (New York Heart Association class II) and chronic systolic heart failure (HF). The present study evaluated the cost-effectiveness of eplerenone in the treatment of these patients in the UK and Spain. Results from the EMPHASIS-HF trial were used to develop a discrete-event simulation model estimating lifetime direct costs and effects (life years and quality-adjusted life years (QALYs) gained) of the addition of eplerenone to standard care among patients with chronic systolic HF and mild symptoms. Eplerenone plus standard care compared with standard care alone increased lifetime direct costs per patient by £4284 for the UK and €7358 for Spain, with additional quality-adjusted life expectancy of 1.22 QALYs for the UK and 1.33 QALYs for Spain. Mean lifetime costs were £3520 per QALY in the UK and €5532 per QALY in Spain. Probabilistic sensitivity analysis suggested a 100% likelihood of eplerenone being regarded as cost-effective at a willingness-to-pay threshold of £20 000 per QALY (UK) or €30 000 per QALY (Spain). By currently accepted standards of value for money, the addition of eplerenone to optimal medical therapy for patients with chronic systolic HF and mild symptoms is likely to be cost-effective.

In June 2016, following the decision of the Supreme Court of Canada to decriminalise assistance in dying, the Canadian government enacted Bill C-14, legalising medical assistance in dying (MAID). In 2014, the province of Quebec had passed end-of-life care legislation making MAID available as of December 2015. The availability of MAID has many implications, including the possibility of combining this practice with organ donation through the controlled donation after cardiac death (cDCD) protocol. cDCD most often occurs in cases where the patient has a severe neurological injury but does not meet all the criteria for brain death. The donation is subsequent to the decision to withdraw life-sustaining treatment (LST). Cases where patients are conscious prior to the withdrawal of LST are unusual, and have raised doubts as to the acceptability of removing organs from individuals who are not neurologically impaired and who have voluntarily chosen to die. These cases can be compared with likely scenarios in which patients will request both MAID and organ donation. In both instances, patients will be conscious and competent. Organ donation in such contexts raises ethical issues regarding respect for autonomy, societal pressure, conscientious objections and the dead-donor rule. In this article, we look at relevant policies in other countries and examine the ethical issues associated with cDCD in conscious patients who choose to die.

Towards a Medicine of the Invisible: bioethics and relationship in "The Little Prince".
Colucci, Massimiliano; Pegoraro, Renzo
2017-03-01
The Little Prince is one of the most famous fables. In this paper, we attempt to look at three bioethical issues through the Little Prince's eyes: the end-of-life context, the patient-physician relationship and prevention/precaution. The fable gives us the basis for a perspective we have called 'Medicine of the Invisible', which is value-focused. The Little Prince suggests that we seek the invisible-the "thing that is important", the "matters of consequence", even on a gnoseological and epistemological level-as a new type of 'clinical data' which may help to make healthcare more ethical and effective. However, this invisible is attainable only within a relationship, in which the physician needs to be tamed by the patient and the patient needs to be tamed by the physician-each one becoming responsible for the other, each one becoming himself through the dialogue with the other. Responsibility is also projected towards the future, against those threats to life that are still unseen and unknown: owning a part of the world entails the ethical imperative to act, in order to safeguard life. But, without a relationship-saturated with lived time, shared experiences, and individual's uniqueness-no meaning and no value can be given. For this reason, the Medicine of the Invisible reminds bioethics that "the thing that is important is the thing that is not seen". Published by the BMJ Publishing Group Limited.

Gaucher disease epidemiology and natural history: a comprehensive review of the literature.
Nalysnyk, Luba; Rotella, Philip; Simeone, Jason C; Hamed, Alaa; Weinreb, Neal

The objectives of this research were: (1) to heighten awareness of Gaucher disease (GD), a rare lysosomal storage disorder with highly heterogeneous patterns of organ involvement and disease severity, to clinicians most likely to encounter these patients, and; (2) to summarize the published evidence on GD epidemiology which is essential to accurately depict the total societal burden of this rare worldwide disorder. A comprehensive literature review was undertaken to summarize the published evidence on the epidemiology of GD. MEDLINE, EMBASE, CENTRAL, and 'grey' literature sources published in English between January 1990 and March 2015 were searched to identify relevant publications. In total, 188 full-text articles were reviewed and findings from 49 studies are summarized herein. The standardized birth incidence of GD in the general population varied from 0.39 to 5.80 per 100 000, and prevalence ranged from 0.70 to 1.75 per 100 000, respectively. Time from onset of GD symptoms to clinical diagnosis was highly variable, with median delays of up to 7 years reported. The incidence and prevalence of GD is substantially higher among the Ashkenazi Jewish population than the general population. Limited epidemiologic information was available from Latin America, Africa, Asia, and developed nations such as the United States, Germany, and the United Kingdom. Signs and symptoms of GD frequently mimic more common hematologic conditions resulting in missed or delayed diagnosis. Early diagnosis and prompt initiation of treatment when indicated is crucial to prevent or minimize life-altering or life-threatening liver and skeletal complications.

Primary care-based comprehensive care programs have the potential to improve outcomes in frail older adults. We evaluated the impact of the Geriatric Care Model (GCM) on the quality of life of community-dwelling frail older adults. A 24-month stepped wedge cluster randomized controlled trial was conducted between May 2010 and March 2013 in 35 primary care practices in the Netherlands, and included 1147 frail older adults. The intervention consisted of a geriatric in-home assessment by a practice nurse, followed by a tailored care plan. Reassessment occurred every six months. Nurses worked together with primary care physicians and were supervised and trained by geriatric expert teams. Complex patients were reviewed in multidisciplinary consultations. The primary outcome was quality of life (SF-12). Secondary outcomes were health-related quality of life, functional limitations, self-rated health, psychological wellbeing, social functioning and hospitalizations. Intention-to-treat analyses based on multilevel modeling showed no significant differences between the intervention group and usual care regarding SF-12 and most secondary outcomes. Only for IADL limitations we found a small intervention effect in patients who received the intervention for 18months (B=-0.25, 95%CI=-0.43 to -0.06, p=0.007), but this effect was not statistically significant after correction for multiple comparisons. The GCM did not show beneficial effects on quality of life in frail older adults in primary care, compared to usual care. This study strengthens the idea that comprehensive care programs add very little to usual primary care for this population. The Netherlands National Trial Register NTR2160.

Recognising colorectal cancer (CRC) patients with Lynch syndrome (LS) can increase life expectancy of these patients and their close relatives. To improve identification of this under-diagnosed disease, experts suggested raising the age limit for CRC tumour genetic testing from 50 to 70 years. The present study evaluates the efficacy and cost-effectiveness of this strategy. Probabilistic efficacy and cost-effectiveness analyses were carried out comparing tumour genetic testing of CRC diagnosed at age 70 or below (experimental strategy) versus CRC diagnosed at age 50 or below (current practice). The proportions of LS patients identified and cost-effectiveness including cascade screening of relatives, were calculated by decision analytic models based on real-life data. Using the experimental strategy, four times more LS patients can be identified among CRC patients when compared with current practice. Both the costs to detect one LS patient (€9437/carrier versus €4837/carrier), and the number needed to test for detecting one LS patient (42 versus 19) doubled. When family cascade screening was included, the experimental strategy was found to be highly cost-effective according to Dutch standards, resulting in an overall ratio of €2703 per extra life-year gained in additionally tested patients. Testing all CRC tumours diagnosed at or below age 70 for LS is cost-effective. Implementation is important as relatives from the large number of LS patients that are missed by current practice, can benefit from life-saving surveillance. © The Author 2014.

To assess the relationships between golf and health. Scoping review. Published and unpublished reports of any age or language, identified by searching electronic databases, platforms, reference lists, websites and from consulting experts. A 3-step search strategy identified relevant published primary and secondary studies as well as grey literature. Identified studies were screened for final inclusion. Data were extracted using a standardised tool, to form (1) a descriptive analysis and (2) a thematic summary. 4944 records were identified with an initial search. 301 studies met criteria for the scoping review. Golf can provide moderate intensity physical activity and is associated with physical health benefits that include improved cardiovascular, respiratory and metabolic profiles, and improved wellness. There is limited evidence related to golf and mental health. The incidence of golfing injury is moderate, with back injuries the most frequent. Accidental head injuries are rare, but can have serious consequences. Practitioners and policymakers can be encouraged to support more people to play golf, due to associated improved physical health and mental well-being, and a potential contribution to increased life expectancy. Injuries and illnesses associated with golf have been identified, and risk reduction strategies are warranted. Further research priorities include systematic reviews to further explore the cause and effect nature of the relationships described. Research characterising golf's contribution to muscular strengthening, balance and falls prevention as well as further assessing the associations and effects between golf and mental health are also indicated.

KnowLife: a versatile approach for constructing a large knowledge graph for biomedical sciences.
Ernst, Patrick; Siu, Amy; Weikum, Gerhard
2015-05-14
Biomedical knowledge bases (KB's) have become important assets in life sciences. Prior work on KB construction has three major limitations. First, most biomedical KBs are manually built and curated, and cannot keep up with the rate at which new findings are published. Second, for automatic information extraction (IE), the text genre of choice has been scientific publications, neglecting sources like health portals and online communities. Third, most prior work on IE has focused on the molecular level or chemogenomics only, like protein-protein interactions or gene-drug relationships, or solely address highly specific topics such as drug effects. We address these three limitations by a versatile and scalable approach to automatic KB construction. Using a small number of seed facts for distant supervision of pattern-based extraction, we harvest a huge number of facts in an automated manner without requiring any explicit training. We extend previous techniques for pattern-based IE with confidence statistics, and we combine this recall-oriented stage with logical reasoning for consistency constraint checking to achieve high precision. To our knowledge, this is the first method that uses consistency checking for biomedical relations. Our approach can be easily extended to incorporate additional relations and constraints. We ran extensive experiments not only for scientific publications, but also for encyclopedic health portals and online communities, creating different KB's based on different configurations. We assess the size and quality of each KB, in terms of number of facts and precision. The best configured KB, KnowLife, contains more than 500,000 facts at a precision of 93% for 13 relations covering genes, organs, diseases, symptoms, treatments, as well as environmental and lifestyle risk factors. KnowLife is a large knowledge base for health and life sciences, automatically constructed from different Web sources. As a unique feature, KnowLife is harvested from different text genres such as scientific publications, health portals, and online communities. Thus, it has the potential to serve as one-stop portal for a wide range of relations and use cases. To showcase the breadth and usefulness, we make the KnowLife KB accessible through the health portal (http://knowlife.mpi-inf.mpg.de).

The present systematic literature review is a part of the 5th revision of the Nordic Nutrition Recommendations. The aim was to assess the health effects of different levels of protein intake in infancy and childhood in a Nordic setting. The initial literature search resulted in 435 abstracts, and 219 papers were identified as potentially relevant. Full paper selection resulted in 37 quality-assessed papers (4A, 30B, and 3C). A complementary search found four additional papers (all graded B). The evidence was classified as convincing, probable, limited-suggestive, and limited-inconclusive. Higher protein intake in infancy and early childhood is convincingly associated with increased growth and higher body mass index in childhood. The first 2 years of life is likely most sensitive to high protein intake. Protein intake between 15 E% and 20 E% in early childhood has been associated with an increased risk of being overweight later in life, but the exact level of protein intake above which there is an increased risk for being overweight later in life is yet to be established. Increased intake of animal protein in childhood is probably related to earlier puberty. There was limited-suggestive evidence that intake of animal protein, especially from dairy, has a stronger association with growth than vegetable protein. The evidence was limited-suggestive for a positive association between total protein intake and bone mineral content and/or other bone variables in childhood and adolescence. Regarding other outcomes, there were too few published studies to enable any conclusions. In conclusion, the intake of protein among children in the Nordic countries is high and may contribute to increased risk of later obesity. The upper level of a healthy intake is yet to be firmly established. In the meantime, we suggest a mean intake of 15 E% as an upper limit of recommended intake at 12 months, as a higher intake may contribute to increased risk for later obesity. PMID:23717219

A Contextual Work-Life Experiences Model to Understand Nurse Commitment and Turnover.

2018-05-17
To present a discussion and model depicting most effecting work life experience contextual factors that influence commitment and turnover intentions for nurses in Sri Lanka. Increasing demand for nurses has made the retention of experienced, qualified nursing staff a priority for health care organizations and highlights the need to capture contextual work-life experiences that influence nurses' turnover decisions. Discussion paper. This discussion paper and model is based on our experiences and knowledge of Sri Lanka and represents an integration of classic turnover research and commitment theory and others published between 1958 - 2017, contextualized to reflect the reality faced by Sri Lanka nurses. The model presents a high-level view of intrinsic, extrinsic, personal and professional antecedents to nurse turnover where relevance can be used by researchers, policy makers, clinicians and educators to establish focused and limited scope models and examine comprehensive contexts. This model emphasizes the role that work-life experiences play to fortify (or weaken) nurses' motivation to remain committed to their organization, profession, family, and country. Understanding of contextual work-life influences on nurses' intent to stay should lead to evidence-based strategies that result in a higher number of nurses wanting to remain in the nursing profession and work in the health sector in Sri Lanka.

Neuromyelitis optica (NMO) is an auto-immune disease that can cause severe visual and mobility impairments. Research on health-related quality of life (HRQoL) in NMO is scarce, limiting knowledge on factors influencing HRQoL and support needs. This study provides the first qualitative exploration of HRQoL in NMO, conducted to provide a conceptual framework for the development of an NMO patient-reported outcome measure. Fifteen people with NMO (aged 18-74; 11 women, 4 men) participated in semi-structured interviews; data were analysed using constant comparative analysis. HRQoL in NMO is a multifaceted concept incorporating highly subjective perceptions of normality and meaning. Four major themes were identified: impact of physical symptoms on daily living, utilizing support to achieve independence, expectations for life and meaningful roles in life and purpose. Themes highlighted the importance of perceived normality, and its relationship to attaining life goals comparable to peers, as underpinning evaluations of HRQoL. Many people with severe disability reported a high HRQoL, suggesting the inappropriateness of assuming a negative HRQoL on the basis of an individual's neurological impairment. These findings further the conceptual understanding of HRQoL in NMO, informing patient-care approaches and the development of an NMO-specific patient-reported outcome measure. © 2015 The Authors.

Previous studies have examined the relationships between structural brain characteristics and early life stress in adults. However, there is limited evidence for functional brain variation associated with early life stress in children. We hypothesized that early life stress and trauma would be associated with increased functional brain activation response to negative emotional faces in children with and without a history of depression. Psychiatric diagnosis and life events in children (starting at age 3-5 years) were assessed in a longitudinal study. A follow-up magnetic resonance imaging (MRI) study acquired data (N = 115 at ages 7-12, 51% girls) on functional brain response to fearful, sad, and happy faces relative to neutral faces. We used a region-of-interest mask within cortico-limbic areas and conducted regression analyses and repeated-measures analysis of covariance. Greater activation responses to fearful, sad, and happy faces in the amygdala and its neighboring regions were found in children with greater life stress. Moreover, an association between life stress and left hippocampal and globus pallidus activity depended on children's diagnostic status. Finally, all children with greater life trauma showed greater bilateral amygdala and cingulate activity specific to sad faces but not the other emotional faces, although right amygdala activity was moderated by psychiatric status. These findings suggest that limbic hyperactivity may be a biomarker of early life stress and trauma in children and may have implications in the risk trajectory for depression and other stress-related disorders. However, this pattern varied based on emotion type and history of psychopathology. Copyright © 2014 American Academy of Child and Adolescent Psychiatry. Published by Elsevier Inc.

An exercise program (EP) during cancer treatment seems to be a valid strategy against physiological and quality-of-life impairments, but scientific evidence of benefits among pediatric patients is still limited. This review summarizes the literature focused on randomized controlled trials of EP offered to patients during leukemia and lymphoma treatment. Studies published up to June 2017 were selected from multiple databases and assessed by three independent reviewers for methodological validity. The review identified eight studies, but several types of bias have to be avoided to provide evidence-based recommendations accessible to patients, families, and professionals. © 2018 Wiley Periodicals, Inc.
Damage tolerance and structural monitoring for wind turbine blades.

The paper proposes a methodology for reliable design and maintenance of wind turbine rotor blades using a condition monitoring approach and a damage tolerance index coupling the material and structure. By improving the understanding of material properties that control damage propagation it will be possible to combine damage tolerant structural design, monitoring systems, inspection techniques and modelling to manage the life cycle of the structures. This will allow an efficient operation of the wind turbine in terms of load alleviation, limited maintenance and repair leading to a more effective exploitation of offshore wind. © 2015 The Author(s) Published by the Royal Society.

2011-12-01
The purpose of this study is to describe and analyse the quality of life of Israeli families raising a child with a disability while challenged with all the usual demands of family life. Respondents were main caregivers of 103 children with disability receiving services at Beit Issie Shapiro, a service agency in Israel. The respondents completed the Family Quality of Life Survey-2006 which operationalises family quality of life (FQOL) as a construct in nine domains of family life. The findings show an underlying pattern within the domains that define FQOL. In general, the findings indicate that the families are strongly challenged to meet the needs of a special child and raise a family meeting the needs of all its members. The respondents report that, within the limits of available opportunities, they had achieved well and they are satisfied with their attainment. In general, our findings seem to reflect in our respondents a sense of resilience and an ability to manage family challenges to achieve a reasonably high FQOL. Domains described as internal to the family were rated highly in terms of FQOL as compared to domains external to the family. The Family Quality of Life Survey-2006 was found to be a valuable tool for identifying and evaluating factors that enhance FQOL. Further research is needed to develop application models for integrating this instrument into the agency's service and evaluation repertoire. © 2011 The Authors.

Background Observation is underused among men with localized, low-risk prostate cancer. Objective To assess the costs and benefits of observation versus initial treatment. Design Decision analysis simulating treatment or observation. Data Sources Medicare schedules, published literature. Target Population Men ages 65 and 75 years with newly diagnosed low-risk prostate cancer (prostate-specific antigen level <10 μg/L, stage ≤T2a, Gleason score ≤3+3). Time Horizon Lifetime. Perspective Societal. Intervention Treatment (brachytherapy, intensity-modulated radiation therapy, or radical prostatectomy) or observation (active surveillance [AS] or watchful waiting [WW]). Outcome Measures Quality-adjusted life expectancy, costs. Results of Base-Case Analysis Observation was more effective and less costly than initial treatment. Compared with AS, WW provided 2 additional months of quality-adjusted life expectancy (9.02 vs. 8.85 years) at a savings of $15 374 ($24 520 vs. $39 894) in men aged 65 years and 2 additional months (6.14 vs. 5.98 years) at a savings of $11 746 ($18 302 vs. $30 048) in men aged 75 years. Brachytherapy was the most effective and least expensive initial treatment. Results of Sensitivity Analysis Treatment became more effective than observation when it led to more dramatic reductions in prostate cancer death (hazard ratio, 0.47 vs. WW and 0.64 vs. AS). Active surveillance became as effective as WW in men aged 65 years when the probability of progressing to treatment on AS decreased below 63% or when the quality of life with AS versus WW was 4% higher in men aged 65 years or 1% higher in men aged 75 years. Watchful waiting remained least expensive in all analyses. Limitation Results depend on outcomes reported in the published literature, which is limited. Conclusion Among these men, observation is more effective and costs less than initial treatment, and WW is most effective and least expensive under a wide range of clinical scenarios.

To investigate agreement between children with visual impairment (VI) and their parents on their ratings of the child's vision-related quality of life (VQoL) and functional vision (FV) using two novel self-report patient-reported outcome measures developed for this population. 99 children aged 10-15 years (mean age=12.2, SD=1.9) with VI (best corrected acuity (logarithm of the minimum angle of resolution) 0.50 or worse in better eye) and their parents participated in a national postal survey, completing the child and proxy versions of our novel instruments assessing VQoL and FV of children with VI-the vision-related quality of life instrument for children and young people (VQoL_CYP) and the functional vision questionnaire for children and young people (FVQ_CYP), respectively. Parent-child agreement was investigated using the Bland-Altman (BA) method. Variation across key sociodemographic and clinical characteristics was examined using the Intraclass Correlation Coefficient. Average parental ratings of their child's VQoL and FV were significantly lower than the children's own ratings, but the range of disagreement was wide, with parents both overestimating and underestimating their child's VQoL (mean score difference=5.7, BA limits of agreement (LOA): lower -22.10 (CI 95% -24.61 to 19.59) and upper 33.50 (CI 95% 30.99 to 36.01)), but more consistently underestimating the child's FV (mean score difference=-11.8, BA LOA: lower -39.60 (CI 95% -42.12 to 37.08) and upper 16 (CI 95% 13.48 to 18.52)). There was variation in agreement by some child characteristics, including vision level, time of onset and course of VI progression. Visually impaired children and their parents perceive the broader impact of living with VI very differently. There is value in routine capture of information independently from children and their parents for comprehensively gauging the impact of childhood VI and tailoring appropriate interventions.

Care farms, where all or part of the farm is used for therapeutic purposes, show much potential for improving the health and well-being of a range of disadvantaged groups. Studies to date have been qualitative or observational, with limited empirical evidence of the effectiveness of care farms in improving health and well-being. Understanding the underlying mechanisms that lead to improvements for different disadvantaged groups is a further gap in the evidence. Participants in this study are offenders serving community orders. Their low socioeconomic status and poor health outcomes relative to the general population exemplifies disadvantage. This paper describes the protocol of a study to understand the impacts of care farms and to pilot the design and tools for a study to assess cost-effectiveness of care farms in improving the quality of life of offenders. As a pilot study, no power calculation has been conducted. However, 150 offenders serving community sentences on care farms and 150 on other probation locations (eg, litter picking, painting) will be recruited over a 1-year period. Changes in quality of life, measured by Clinical Outcome in Routine Evaluation-Outcome Measure, health and reconvictions of offenders at care farms compared to other probation locations will be analysed to inform the sample size calculation for the follow on study. The feasibility of recruitment, retention, collecting cost data and modelling cost-effectiveness will also be assessed. The study will use qualitative methods to explore the experiences of offenders attending care farms and perceptions of probation and care farm staff on the processes and impacts of the intervention. Findings will be published and inform development of a natural experiment and will be disseminated to probation services, care farms and academics.

The Significance of Sexuality and Intimacy in the Lives of Older African Americans With HIV/AIDS.
Nevedal, Andrea; Sankar, Andrea
2016-08-01
Aging and HIV/AIDS research focuses primarily on standardized clinical, social, and behavioral measures, leaving unanswered questions about how this chronic and stigmatizing condition affects life course expectations and the meaning of aging with the disease. Utilizing Gaylene Becker's (1997) life course disruption theory, we explored older African Americans' experiences of living with HIV/AIDS. A purposive sample (N = 43) of seropositive African Americans aged 50 and older was selected from a parent study. Thirteen participants completed one semi-structured in-depth interview on life course expectations and experiences of living with HIV/AIDS. Interview transcripts were analyzed using standard qualitative coding and thematic analysis. Responding to broad, open-ended questions about the impact of HIV on life course expectations, participants emphasized how HIV limited their ability to experience sexuality and intimacy. Two major themes emerged, damaged sexuality and constrained intimacy. Older African Americans' discussions of living with HIV focused on the importance of and the challenges to sexuality and intimacy. Researchers and clinicians should be attentive to significant and ongoing HIV-related challenges to sexuality and intimacy facing older African Americans living with HIV/AIDS. © The Author 2015.

Background Smoking, alcohol consumption, poor diet and low levels of physical activity significantly contribute to the burden of illness in developed countries. Whilst the links between specific and multiple risk behaviours and individual chronic conditions are well documented, the impact of these behaviours in mid-life across a range of later life outcomes has yet to be comprehensively assessed. This review aimed to provide an overview of behavioural risk factors in mid-life that are associated with successful ageing and the primary prevention or delay of disability, dementia, frailty and non-communicable chronic conditions. Methods A literature search was conducted to identify cohort studies published in English since 2000 up to Dec 2014. Multivariate analyses and a minimum follow-up of five years were required for inclusion. Two reviewers screened titles, abstracts and papers independently. Studies were assessed for quality. Evidence was synthesised by mid-life behavioural risk for a range of late life outcomes. Findings This search located 10,338 individual references, of which 164 are included in this review. Follow-up data ranged from five years to 36 years. Outcomes include dementia, frailty, disability and cardiovascular disease. There is consistent evidence of beneficial associations between mid-life physical activity, healthy ageing and disease outcomes. Across all populations studied there is consistent evidence that mid-life smoking has a detrimental effect on health. Evidence specific to alcohol consumption was mixed. Limited, but supportive, evidence was available relating specifically to mid-life diet, leisure and social activities or health inequalities. Conclusions There is consistent evidence of associations between mid-life behaviours and a range of late life outcomes. The promotion of physical activity, healthy diet and smoking cessation in all mid-life populations should be encouraged for successful ageing and the prevention of disability and chronic disease.

Although heart failure negatively affects the health-related quality of life of Spanish patients there is little information on the clinical factors associated with this issue. Cross-sectional multicenter study of health-related quality of life. A specific questionnaire (Kansas City Cardiomyopathy Questionnaire) and a generic questionnaire (EuroQoL-5D) were administered to 1037 consecutive outpatients with systolic heart failure. Most patients with poor quality of life had a worse prognosis and increased severity of heart failure. Mobility was more limited and rates of pain/discomfort and anxiety/depression were higher in the study patients than in the general population and patients with other chronic conditions. The scores on both questionnaires were very highly correlated (Pearson r =0.815; P < .001). Multivariable linear regression showed that being older (standardized β=-0.2; P=.03), female (standardized β=-10.3; P < .001), having worse functional class (standardized β=-20.4; P < .001), a higher Charlson comorbidity index (standardized β=-1.2; P=.005), and recent hospitalization for heart failure (standardized β=6.28; P=.006) were independent predictors of worse health-related quality of life. Patients with heart failure have worse quality of life than the general Spanish population and patients with other chronic diseases. Female sex, being older, comorbidity, advanced symptoms, and recent hospitalization are determinant factors in health-related quality of life in these patients.

Generalizability of cost-utility analyses across countries and settings.
Ginsberg, Gary M
2013-12-01
All societies have limited resources, so decisions have to be made about which public health interventions should be provided. A major tool used for prioritisation is cost-utility analysis (CUA) where the outcomes are measured in terms of Disability Adjusted Life Years (DALYs) prevented. Collecting data and building models to calculate the ratio of net costs (i.e.: intervention costs less treatment costs averted due to decreases in morbidity and mortality) to outcomes (CUR) is complex and time consuming. Therefore, there is a great appeal in using CUA calculations that have already been published in other countries. This paper points out the many limitations and inaccuracies caused by generalizing results from CUAs across different countries. However, if time constraints are pressing then first-order estimates of results could be presented after adjustments for the major drivers of the CUR, such as incidence rates, intervention costs and averted treatment costs.

Life cycle environmental impacts of vacuum cleaners and the effects of European regulation.
Gallego-Schmid, Alejandro; Mendoza, Joan Manuel F; Jeswani, Harish Kumar; Azapagic, Adisa
2016-07-15
Energy efficiency of vacuum cleaners has been declining over the past decades while at the same time their number in Europe has been increasing. The European Commission has recently adopted an eco-design regulation to improve the environmental performance of vacuum cleaners. In addition to the existing directive on waste electrical and electronic equipment (WEEE), the regulation could potentially have significant effects on the environmental performance of vacuum cleaners. However, the scale of the effects is currently unknown, beyond scant information on greenhouse gas emissions. Thus, this paper considers for the first time life cycle environmental impacts of vacuum cleaners and the effects of the implementation of these regulations at the European level. The effects of electricity decarbonisation, product lifetime and end-of-life disposal options are also considered. The results suggest that the implementation of the eco-design regulation alone will reduce significantly the impacts from vacuum cleaners (37%-44%) by 2020 compared with current situation. If business as usual continued and the regulation was not implemented, the impacts would be 82%-109% higher by 2020 compared to the impacts with the implementation of the regulation. Improvements associated with the implementation of the WEEE directive will be much smaller (<1% in 2020). However, if the WEEE directive did not exist, then the impacts would be 2%-21% higher by 2020 relative to the impacts with the implementation of the directive. Further improvements in most impacts (6%-20%) could be achieved by decarbonising the electricity mix. Therefore, energy efficiency measures must be accompanied by appropriate actions to reduce the environmental impacts of electricity generation; otherwise, the benefits of improved energy efficiency could be limited. Moreover, because of expected lower life expectancy of vacuum cleaners and limited availability of some raw materials, the eco-design regulation should be broadened to reduce the impacts from raw materials, production and end-of-life management.

Occupational exposure to manufactured nano-objects and their agglomerates, and aggregates (NOAA) has been described in several workplace air monitoring studies. However, data pooling for general conclusions and exposure estimates are hampered by limited exposure data across the occupational life cycle of NOAA and a lack in comparability between the methods of collecting and analysing the data. By applying a consistent method of collecting and analysing the workplace exposure data, this study aimed to provide information about the occupational NOAA exposure levels across various life cycle stages of NOAA in the Netherlands which can also be used for multi-purpose use. Personal/near field task-based exposure data was collected using a multi-source exposure assessment method collecting real time particle number concentration, particle size distribution (PSD), filter-based samples for morphological, and elemental analysis and detailed contextual information. A decision logic was followed allowing a consistent and objective way of analysing the exposure data. In total, 46 measurement surveys were conducted at 15 companies covering 18 different exposure situations across various occupational life cycle stages of NOAA. Highest activity-effect levels were found during replacement of big bags (<1000-76000 # cm(-3)), mixing/dumping of powders manually (<1000-52000 # cm(-3)) and mechanically (<1000-100000 # cm(-3)), and spraying of liquid (2000-800000 # cm(-3)) showing a high variability between and within the various exposure situations. In general, a limited change in PSD was found during the activity compared to the background. This broad-scale exposure study gives a comprehensive overview of the NOAA exposure situations in the Netherlands and an indication of the levels of occupational exposure to NOAA across various life cycle of NOAA. The collected workplace exposure data and contextual information will serve as basis for future pooling of data and modelling of worker exposure. © The Author 2015.

A deterministic computer simulation model of life-cycle lamb and wool production.
Wang, C T; Dickerson, G E
1991-11-01
A deterministic mathematical computer model was developed to simulate effects on life-cycle efficiency of lamb and wool production from genetic improvement of performance traits under alternative management systems. Genetic input parameters can be varied for age at puberty, length of anestrus, fertility, precocity of fertility, number born, milk yield, mortality, growth rate, body fat, and wool growth. Management options include mating systems, lambing intervals, feeding levels, creep feeding, weaning age, marketing age or weight, and culling policy. Simulated growth of animals is linear from birth to inflection point, then slows asymptotically to specified mature empty BW and fat content when nutrition is not limiting. The ME intake requirement to maintain normal condition is calculated daily or weekly for maintenance, protein and fat deposition, wool growth, gestation, and lactation. Simulated feed intake is the minimum of availability, DM physical limit, or ME physiological limit. Tissue catabolism occurs when intake is below the requirement for essential functions. Mortality increases when BW is depressed. Equations developed for calculations of biological functions were validated with published and unpublished experimental data. Lifetime totals are accumulated for TDN, DM, and protein intake and for market lamb equivalent output values of empty body or carcass lean and wool from both lambs and ewes. These measures of efficiency for combinations of genetic, management, and marketing variables can provide the relative economic weighting of traits needed to derive optimal criteria for genetic selection among and within breeds under defined industry production systems.

Myths and realities of the 80-hour work week.
Schenarts, Paul J; Anderson Schenarts, Kimberly D; Rotondo, Michael F
2006-01-01
Myths are so ingrained into cultural traditions that emotion frequently overshadows a rational evaluation of the facts. The reduction in resident work hours has resulted in the formation of several myths. The purpose of this review is to examine the published data on resident work hours to separate out myth from reality. An electronic database was searched for publications related to resident training, work-hours, continuity of care, sleep deprivation, quality of life, patient safety, clinical/operative experience, faculty work hours, and surgical education. Sleep deprivation has been shown to be harmful, and residents played a role in advocating for work-hour limits. Surgical residents have seen a less dramatic improvement in quality of life compared with other disciplines. Work-hour reductions have decreased participation in clinic but have not resulted in a significant decline in clinical or operative exposure. Limiting resident work hours will unlikely result in a decrease health-care cost. Reduction in resident work hours has not resulted in an improvement or deterioration in patient outcome. Reduction of work hours has not increased faculty work hours nor made surgery a more attractive career choice. Despite strongly held opinions, resident work-hour reduction has resulted in little significant change in lifestyle, clinical exposure, patient well-being, faculty work hours, or medical student recruitment.
The deep-sea under global change.
Danovaro, Roberto; Corinaldesi, Cinzia; Dell'Anno, Antonio; Snelgrove, Paul V R
2017-06-05
The deep ocean encompasses 95% of the oceans' volume and is the largest and least explored biome of Earth's Biosphere. New life forms are continuously being discovered. The physiological mechanisms allowing organisms to adapt to extreme conditions of the deep ocean (high pressures, from very low to very high temperatures, food shortage, lack of solar light) are still largely unknown. Some deep-sea species have very long life-spans, whereas others can tolerate toxic compounds at high concentrations; these characteristics offer an opportunity to explore the specialized biochemical and physiological mechanisms associated with these responses. Widespread symbiotic relationships play fundamental roles in driving host functions, nutrition, health, and evolution. Deep-sea organisms communicate and interact through sound emissions, chemical signals and bioluminescence. Several giants of the oceans hunt exclusively at depth, and new studies reveal a tight connection between processes in the shallow water and some deep-sea species. Limited biological knowledge of the deep-sea limits our capacity to predict future response of deep-sea organisms subject to increasing human pressure and changing global environmental conditions. Molecular tools, sensor-tagged animals, in situ and laboratory experiments, and new technologies can enable unprecedented advancement of deep-sea biology, and facilitate the sustainable management of deep ocean use under global change.

Untreated perinatal paternal depression: Effects on offspring.
Gentile, Salvatore; Fusco, Maria Luigia
2017-06-01
Transition to parenthood represents an important life event which increases vulnerability to psychological disorders. Aim of this article is to analyze all studies which investigated the effects of untreated perinatal paternal depression in offspring. We searched pertinent, peer-reviewed articles published in English (January 1980 to April 2016) on MEDLINE, PsycINFO, and Science.gov. Twenty-three studies met the inclusion criteria. Most of the reviewed studies suffer from methodological limitations, including the small sample, the lack of a structured psychiatric diagnosis, and inclusion bias. Despite such limitations, paternal depression seems to be associated with an increased risk of developmental and behavioural problems and even psychiatric disorders in offspring. In particular, in infants and toddlers such problems vary from increased crying to hyperactivity and conduct problems to psychological and developmental impairment, and poor social outcomes. School-age children of depressed fathers have a doubled risk for suffering from specific psychiatric disorders. Hence, facilitating access to vigorous and evidence based treatments is a public health opportunity for improving the quality of life of depressed parents and their children. Evidences emerging from this review actually suggest that the traditional gender-focused approach to perinatal mood disorders should be completed by a family-centred approach, in order to improve the effectiveness of perinatal mental health programs.

Obesity: the new childhood disability?
Tsiros, M D; Coates, A M; Howe, P R C; Grimshaw, P N; Buckley, J D
2011-01-01
This review addresses the impact of obesity on paediatric physical functioning utilizing the World Health Organization International Classification of Functioning, Disability and Health Framework (ICF). The ICF encompasses functioning (as it relates to all body functions and structures), activities (undertaking a particular task) and participation (in a life situation) with disability referring to impairments in body functions/structures, activity restrictions or participation limitations. Electronic databases were searched for peer-reviewed studies published in English prior to May 2009 that examined aspects of physical functioning in children (≤18 years). Eligible studies (N = 104) were ranked by design and synthesized descriptively. Childhood obesity was found to be associated with deficits in function, including impaired cardiorespiratory fitness and performance of motor tasks; and there was some limited evidence of increased musculoskeletal pain and decrements in muscle strength, gait and balance. Health-related quality of life and the subset of physical functioning was inversely related to weight status. However, studies investigating impacts of obesity on wider activity and participation were lacking. Further research utilizing the ICF is required to identify and better characterize the effects of paediatric obesity on physical function, activity and participation, thereby improving targets for intervention to reduce disability in this population. © 2010 The Authors. obesity reviews © 2010 International Association for the Study of Obesity.

Chronic respiratory diseases often cause impairment in the functions and/or structure of the respiratory system, and impose limitations on different activities in the lives of persons who suffer them. In younger patients with an active working life, these limitations can cause problems in carrying out their normal work. Article 41 of the Spanish Constitution states that «the public authorities shall maintain a public Social Security system for all citizens guaranteeing adequate social assistance and benefits in situations of hardship». Within this framework is the assessment of fitness for work, as a dual-nature process (medico-legal) that aims to determine whether it is appropriate or not to recognise a person's right to receive benefits which replace the income that they no longer receive as they cannot carry out their work, due to loss of health. The role of the pulmonologist is essential in evaluating the diagnosis, treatment, prognosis and functional capacity of respiratory patients. These recommendations seek to bring the complex setting of fitness for work evaluation to pulmonologists and thoracic surgeons, providing action guidelines that allow them to advise their own patients about their incorporation into working life.

There is limited research exploring the pain experience of boys and young men with Duchenne Muscular Dystrophy. We conducted a mixed-methods pilot study to assess the feasibility of using particular measures of pain, pain coping and quality of life within semi-structured interviews with boys and young men with Duchenne Muscular Dystrophy and a postal survey of their parents. Non-probability, convenience sampling was used. Twelve young men aged 11-21 years (median 15 years), three of whom were still ambulant, and their parents/guardians were recruited. The measures used were acceptable to the young men and demonstrated potential to provide useful data. Two-thirds of young men suffered from significant daily pain which was associated with reduced quality of life. Pain complaints were largely kept within the family. Young men's pain-coping strategies were limited by their restricted physical abilities. Statistical power based on these preliminary results suggests a study of approximately 50 boys/young men which appears feasible. Further study is needed to explore acceptable and effective methods of pain management in this population and ways of enhancing pain-coping strategies. In clinical practice, assessment of pains and discomfort should form part of all routine consultations. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

This study investigates the efficiency of two types of rehabilitation methods based on economic justification that can lead to logical decision making between the retrofitting schemes. Among various rehabilitation methods, concentric chevron bracing (CCB) and cylindrical friction damper (CFD) were selected. The performance assessment procedure of the frames is divided into two distinct phases. First, the limit state probabilities of the structures before and after rehabilitation are investigated. In the second phase, the seismic risk of structures in terms of life safety and financial losses (decision variables) using the recently published FEMA P58 methodology is evaluated. The results show that the proposed retrofitting methods improve the serviceability and life safety performance levels of steel and RC structures at different rates when subjected to earthquake loads. Moreover, these procedures reveal that financial losses are greatly decreased, and were more tangible by the application of CFD rather than using CCB. Although using both retrofitting methods reduced damage state probabilities, incorporation of a site-specific seismic hazard curve to evaluate mean annual occurrence frequency at the collapse prevention limit state caused unexpected results to be obtained. Contrary to CFD, the collapse probability of the structures retrofitted with CCB increased when compared with the primary structures.

There are limited data describing the epidemiology, management and outcomes of children with toxic shock syndrome (TSS), a potentially life-threatening illness. Here, we describe the incidence, clinical features, treatment and outcome of children with staphylococcal and streptococcal TSS in Victoria, Australia. Retrospective chart review of children admitted between 2003 and 2014 to two tertiary paediatric referral centres who fulfilled the Centers for Disease Control and Prevention case definition of TSS. There were 62 cases over the 11-year period; 43 staphylococcal TSS and 19 streptococcal TSS. The majority (46 (74%)) of cases were admitted to an intensive care unit and 44 (71%) required inotropic support. Compared with those with staphylococcal TSS, patients with streptococcal TSS were younger, more unwell and more likely to have residual morbidity. Adjunctive therapy with intravenous immunoglobulin or clindamycin was used in 58 (94%) of cases and fresh frozen plasma was used in 15 (24%). Seven patients received extracorporeal membrane oxygenation. All patients survived. This study highlights the importance of early recognition of TSS and supports rapid tertiary referral and intensive care management, which includes the use of adjunctive therapy with intravenous immunoglobulin and clindamycin.

Prediction of psychosis in patients at clinical high risk (CHR) has become a mainstream focus of clinical and research interest worldwide. When using CHR instruments for clinical purposes, the predicted outcome is but only a probability; and, consequently, any therapeutic action following the assessment is based on probabilistic prognostic reasoning. Yet, probabilistic reasoning makes considerable demands on the clinicians. We provide here a scholarly practical guide summarising the key concepts to support clinicians with probabilistic prognostic reasoning in the CHR state. We review risk or cumulative incidence of psychosis in, person-time rate of psychosis, Kaplan-Meier estimates of psychosis risk, measures of prognostic accuracy, sensitivity and specificity in receiver operator characteristic curves, positive and negative predictive values, Bayes' theorem, likelihood ratios, potentials and limits of real-life applications of prognostic probabilistic reasoning in the CHR state. Understanding basic measures used for prognostic probabilistic reasoning is a prerequisite for successfully implementing the early detection and prevention of psychosis in clinical practice. Future refinement of these measures for CHR patients may actually influence risk management, especially as regards initiating or withholding treatment. Published by the BMJ Publishing Group Limited.

Public health strategies have placed increasing emphasis on psychosocial and arts-based strategies for promoting well-being. This study presents preliminary findings for a specific literary-based intervention, Shared Reading, which provides community-based spaces in which individuals can relate with both literature and one another. A 12-week crossover design was conducted with 16 participants to compare benefits associated with six sessions of Shared Reading versus a comparison social activity, Built Environment workshops. Data collected included quantitative self-report measures of psychological well-being, as well as transcript analysis of session recordings and individual video-assisted interviews. Qualitative findings indicated five intrinsic benefits associated with Shared Reading: liveness, creative inarticulacy, the emotional, the personal and the group (or collective identity construction). Quantitative data additionally showed that the intervention is associated with enhancement of a sense of 'Purpose in Life'. Limitations of the study included the small sample size and ceiling effects created by generally high levels of psychological well-being at baseline. The therapeutic potential of reading groups is discussed, including the distinction between instrumental and intrinsic value within arts-and-health interventions.

Cohort studies have reported that midlife high total serum cholesterol (TC) is associated with increased risk of Alzheimer's disease (AD) in late-life but findings have been based on few studies and previous reviews have been limited by a lack of compatible data. We synthesized all high quality data from cohort studies reporting on the association between total serum cholesterol measured and late-life cognitive outcomes including Alzheimer's disease (AD), vascular dementia (VaD), any dementia, mild cognitive impairment (MCI), and cognitive decline. The literature was searched up to October 2016 using a registered protocol. Thirty-four articles meeting study criteria were identified. Seventeen studies published from 1996 to 2014, including 23,338 participants were included in meta-analyses. Relative risk of developing AD for adults with high TC in midlife was 2.14 (95% CI 1.33-3.44) compared with normal cholesterol. Individual studies that could not be pooled also reported high TC in midlife increased the risk of MCI and cognitive decline in late-life. High TC in late-life was not associated with MCI, AD, VaD, any dementia, or cognitive decline. Late-life measured HDL cholesterol and triglycerides were not associated with increased risk of VaD, and HDL was not associated with risk of MCI, AD, or any dementia. There were insufficient data to examine other cholesterol sub-fractions, sex differences, or APOE interactions. Significant gaps in the literature regarding TC and late-life dementia remain. Evidence suggests that high midlife TC increases risk of late-life AD, and may correlate with the onset of AD pathology.

Vitiligo is the most common pigmentation disorder. It is an acquired, progressive disorder, presenting with white macules that can appear anywhere on the skin. Presently, there is no cure for vitiligo. Although there are therapies targeted at improving its appearance, their effectiveness is limited. Without satisfactory solution to vitiligo, patients are permanently disfigured for life. Quality of life of vitiligo patients has been commonly found to be moderately impaired. Patients are chronically embarrassed and depressed. Stigmatisation is also common and cause marginalization. Hence, while vitiligo is not "life-threatening", it can be "life-ruining". Because current treatments are unsatisfactory in repigmenting the skin, the question of continuing treatment must also consider the benefits to quality of life, and that is the purpose of this review. The overall objective of this systematic review was to examine the effectiveness of therapeutic interventions, in terms of quality of life for adult patients with vitiligo. Types of studies - The review considered quantitative papers, including randomised controlled trials and quasi-experimental studies.Types of participants - Adult patients who have vitiligo from 18 to 75 years-old.Types of interventions - This review considered studies of current therapeutic interventions for vitiligo, including oral, topical, combination, camouflage, cognitive-behavioural therapy and grafting.Types of measured outcomes - Quality of life outcomes as measured by validated tools. The search aimed to find published studies and papers, limited to English language reports. A three-step search strategy was utilised: An initial limited search of MEDLINE and CINAHL was undertaken, followed by an analysis of the text words contained in the title and abstract, and of the index terms used to describe the article. A second search using all identified keywords and index terms were then undertaken. Search strategies were developed using terms that were specific to the databases. Thirdly, the reference lists of all identified papers were searched for additional studies. The databases searched include: PubMed, CINAHL, Scopus, JSTOR, ScienceDirect,PsycARTICLES (Ovid) and PsycINFO (Ovid) DATA COLLECTION: Two reviewers critically appraised the methodological quality of research studies using a standardised critical appraisal tool from the Joanna-Briggs Institute. Data was extracted from nine papers for this review, however as the studies were heterogeneous in population, interventions and methodologies, it was not possible to conduct a meta-analysis to establish superiority of interventions in terms of improving quality of life. Hence, a narrative summary was presented to collate the results of the interventions where there were similar. All treatments were found to improve quality of life for vitiligo patients. Disease-altering interventions that were effective in repigmentation arrest of disease progression were also effective in improving quality of life. Lifestyle-altering interventions were found to be selectively effective for patients with more severe quality of life impairment and Subscale analysis showed particular effectiveness of interventions in improving the emotional dimension of quality of life. Current interventions for vitiligo are effective in bettering the quality of life either by improving physical appearance of the patient or by addressing the psychological distress directly. Less effectiveness was achieved for the functional and social dimensions, which are more dependent on social and cultural norms. This suggests that current interventions alone are inadequate to address the holistic quality of life challenges associated with vitiligo. IMPLICATIONS FOR RESEARCH.

To date, no research has been published on the health related quality of life (HRQOL) and mental health of children with spinal cord injury and disorders (SCI/D) in Latin America, although limited previous research in Western countries has demonstrated the debilitating and chronic nature of these conditions in children. The aim was to examine the connections between HRQOL and mental health in children with SCI/D from Neiva, Colombia. Thirty children (8- 17 years) were recruited from the Hospital Universatario Hernando Mocaleano Perdomo in Neiva, Colombia. Participants completed self-report measures administered verbally by trained research staff. A correlation matrix generally suggested that higher HRQOL was robustly associated with better mental health. A series of multiple regressions found that HRQOL explained 50.5% of the variance in children's depression, 31.5% of the variance in worry, and 41.9% of the variance in social anxiety. Within these regressions, emotional and social functioning were uniquely associated with depression, and emotional functioning was uniquely associated with social anxiety. This is the first published study to examine psychosocial outcomes in children with SCI/D in Latin America, and its findings suggest that future research and interventions for children with SCI/D in Colombia - and possibly in other regions of Latin America - would benefit from emphasizing emotional and social functioning.

Sex differences in brain development and aging are important to identify, as they may help to understand risk factors and outcomes in brain disorders that are more prevalent in one sex compared with the other. Brain imaging techniques have advanced rapidly in recent years, yielding detailed structural and functional maps of the living brain. Even so, studies are often limited in sample size, and inconsistent findings emerge, one example being varying findings regarding sex differences in the size of the corpus callosum. More recently, large-scale neuroimaging consortia such as the Enhancing Neuro Imaging Genetics through Meta Analysis Consortium have formed, pooling together expertise, data, and resources from hundreds of institutions around the world to ensure adequate power and reproducibility. These initiatives are helping us to better understand how brain structure is affected by development, disease, and potential modulators of these effects, including sex. This review highlights some established and disputed sex differences in brain structure across the life span, as well as pitfalls related to interpreting sex differences in health and disease. We also describe sex-related findings from the ENIGMA consortium, and ongoing efforts to better understand sex differences in brain circuitry. © 2016 The Authors.

The topological architecture of the whole-brain functional networks in those with and without late-life depression (LLD) and amnestic mild cognitive impairment (aMCI) are unknown. To investigate the differences in the small-world measures and the modular community structure of the functional networks between patients with LLD and aMCI when occurring alone or in combination and cognitively healthy non-depressed controls. 79 elderly participants (LLD (n=23), aMCI (n=18), comorbid LLD and aMCI (n=13), and controls (n=25)) completed neuropsychiatric assessments. Graph theoretical methods were employed on resting-state functional connectivity MRI data. LLD and aMCI comorbidity was associated with the greatest disruptions in functional integration measures (decreased global efficiency and increased path length); both LLD groups showed abnormal functional segregation (reduced local efficiency). The modular network organisation was most variable in the comorbid group, followed by patients with LLD-only. Decreased mean global, local and nodal efficiency metrics were associated with greater depressive symptom severity but not memory performance. Considering the whole brain as a complex network may provide unique insights on the neurobiological underpinnings of LLD with and without cognitive impairment.

Rapid response systems are commonly employed by hospitals to identify and respond to deteriorating patients outside of the intensive care unit. Controversy exists about the benefits of rapid response systems. We aimed to review the current state of the rapid response literature, including evolving aspects of afferent (risk detection) and efferent (intervention) arms, outcome measurement, process improvement, and implementation. Articles written in English and published in PubMed. Rapid response systems are heterogeneous, with important differences among afferent and efferent arms. Clinically meaningful outcomes may include unexpected mortality, in-hospital cardiac arrest, length of stay, cost, and processes of care at end of life. Both positive and negative interventional studies have been published, although the two largest randomized trials involving rapid response systems - the Medical Early Response and Intervention Trial (MERIT) and the Effect of a Pediatric Early Warning System on All-Cause Mortality in Hospitalized Pediatric Patients (EPOCH) trial - did not find a mortality benefit with these systems, albeit with important limitations. Advances in monitoring technologies, risk assessment strategies, and behavioral ergonomics may offer opportunities for improvement. Rapid responses may improve some meaningful outcomes, although these findings remain controversial. These systems may also improve care for patients at the end of life. Rapid response systems are expected to continue evolving with novel developments in monitoring technologies, risk prediction informatics, and work in human factors. Copyright © 2018 Elsevier B.V.

Intractable hematuria from the bladder or the prostate can be life-threatening and its management remains a difficult clinical problem. Severe bleeding can arise as a result of radiation cystitis, bladder carcinoma, cyclophosphamide-induced cystitis, severe infection, transurethral resection of the prostate and prostate cancer. When irrigation of the bladder through a three-way catheter and fulguration of the bleeding lesions fail to stop the hematuria, a life-threatening situation can develop, when blood transfusion fails to keep pace with the rate of blood loss. Patients with massive uncontrollable hematuria are often elderly and unfit for cystectomy as a treatment. Many urologists have had to manage this difficult problem, and several different treatments have been attempted and described, with varying degrees of success. Transcatheter arterial embolization of the vesical or prostatic arteries is occasionally indicated in these patients when all other measures have failed. There is limited published experience with this procedure, but success in 90% of patients is reported when the vesical or prostatic arteries can be identified. The aim of this review is to describe the current place of transcatheter arterial embolization in the management of severe bladder or prostate bleeding after failed conservative therapy, and to review its efficacy and morbidity.

To develop, test and validate a versatile questionnaire, the East Midlands Evaluation Tool (EMET), for measuring effects of end of life care training events on trainees' self-reported confidence and competence. A paper-based questionnaire was designed on the basis of the English Department of Health's core competences for end of life care, with sections for completion pretraining, immediately post-training and also for longer term follow-up. Preliminary versions were field tested at 55 training events delivered by 13 organisations to 1793 trainees working in diverse health and social care backgrounds. Iterative rounds of development aimed to maximise relevance to events and trainees. Internal consistency was assessed by calculating interitem correlations on questionnaire responses during field testing. Content validity was assessed via qualitative content analysis of (1) responses to questionnaires completed by field tester trainers and (2) field notes from a workshop with a separate cohort of experienced trainers. Test-retest reliability was assessed via repeat administration to a cohort of student nurses. The EMET comprises 27 items with Likert-scaled responses supplemented with questions seeking free-text responses. It measures changes in self-assessed confidence and competence on 5 subscales: communication skills; assessment and care planning; symptom management; advance care planning; overarching values and knowledge. Test-retest reliability was found to be good, as was internal consistency: the questions successfully assess different aspects of the same underlying concept. The EMET provides a time-efficient, reliable and flexible means of evaluating effects of training on self-reported confidence and competence in the key elements of end of life care.

Evidence currently suggests that many people would prefer to die at home. However, optimal end-of-life homecare depends on the patient's ability to express their care preferences, prognostic awareness, complexity of care, concordance of patient/carer preferences and availability of appropriate services/support. This study explores Irish Head and Neck Cancer (HNC) patient and caregivers' views on end-of-life care (EoLC), an area hitherto little studied. Qualitative data were collected using semistructured, one-to-one interviews with HNC patients with therapeutic experience and their nearest caregivers (n=10, 7 patients, 3 carers). Interview topic guide was developed from the PRISMA EoLC survey. Thematic content analysis was employed to interpret findings. Thematic analysis identified five broad EoLC themes: prognostication, decision making, preferred focus of care/advanced care planning (ACP), preferred place of care/death, perceived barriers/supports to home death. Participants were very willing to discuss most aspects of EoLC, exhibiting no signs of distress. Patients were reluctant to discuss preferred focus-of-care and ACP. This seemed linked to an overly optimistic view of aggressive medical intervention. While carers favoured full patient involvement in decision making, patients were divided between wanting autonomy and those preferring a more passive approach. All expressed a preference for homecare, and most felt they would ideally prefer to die at home. However, decision making was considered a complex process intertwined with risks, responsibilities and commitments to others. Carer burden and symptom control were major concerns. Normalising discussions on EoLC may benefit those affected by HNC. However, in HNC, this needs to be done alongside discussions regarding potentially life-extending treatment, symptom management and support. Published by the BMJ Publishing Group Limited.

To determine the role played by law in medical specialists' decision-making about withholding and withdrawing life-sustaining treatment from adults who lack capacity, and the extent to which legal knowledge affects whether law is followed. Cross-sectional postal survey of medical specialists. The two largest Australian states by population. 649 medical specialists from seven specialties most likely to be involved in end-of-life decision-making in the acute setting. Compliance with law and the impact of legal knowledge on compliance. 649 medical specialists (of 2104 potential participants) completed the survey (response rate 31%). Responses to a hypothetical scenario found a potential low rate of legal compliance, 32% (95% CI 28% to 36%). Knowledge of the law and legal compliance were associated: within compliers, 86% (95% CI 83% to 91%) had specific knowledge of the relevant aspect of the law, compared with 60% (95% CI 55% to 65%) within non-compliers. However, the reasons medical specialists gave for making decisions did not vary according to legal knowledge. Medical specialists prioritise patient-related clinical factors over law when confronted with a scenario where legal compliance is inconsistent with what they believe is clinically indicated. Although legally knowledgeable specialists were more likely to comply with the law, compliance in the scenario was not motivated by an intention to follow law. Ethical considerations (which are different from, but often align with, law) are suggested as a more important influence in clinical decision-making. More education and training of doctors is needed to demonstrate the role, relevance and utility of law in end-of-life care. Published by the BMJ Publishing Group Limited.

There is a growing emphasis on the perspective of individuals living with diabetes and the need for a more person-centred diabetes care. At present, the Swedish National Diabetes Register (NDR) lacks patient-reported outcome measures (PROMs) based on the perspective of the patient. As a basis for a new PROM, the aim of this study was to describe important aspects in life for adult individuals with diabetes. Semistructured qualitative interviews analysed using content analysis. Hospital-based outpatient clinics and primary healthcare clinics in Sweden. 29 adults with type 1 diabetes mellitus (DM) (n=15) and type 2 DM (n=14). Swedish adults (≥ 18 years) living with type 1 DM or type 2 DM (duration ≥ 5 years) able to describe their situation in Swedish. Purposive sampling generated heterogeneous characteristics. To live a good life with diabetes is demanding for the individual, but experienced barriers can be eased by support from others in the personal sphere, and by professional support from diabetes care. Diabetes care was a crucial resource to nurture the individual's ability and knowledge to manage diabetes, and to facilitate life with diabetes by supplying support, guidance, medical treatment and technical devices tailored to individual needs. The analysis resulted in the overarching theme 'To live a good life with diabetes' constituting the two main categories 'How I feel and how things are going with my diabetes' and 'Support from diabetes care in managing diabetes' including five different categories. Common aspects were identified including the experience of living with diabetes and support from diabetes care. These will be used to establish a basis for a tailored PROM for the NDR.

To better understand the patient's perspective of pulmonary hypertension (PH), including the impact of living with PH, disease management and treatment. This qualitative ethnographic study collected observational video footage, supplemented by field notes and patient diaries to assess the impact of PH on the patient's life. Patients were observed and filmed in their home for up to 6 h, capturing the environment, interactions and activities of everyday life. Patients with pulmonary arterial hypertension (PAH) or chronic thromboembolic PH who were receiving PAH-specific medication were recruited through healthcare professionals (HCPs) and patient associations in seven countries across four continents. Sampling was purposive and subgroup analysis was not intended. Overall, 39 patients with PH were enrolled. Many patients had a poor understanding of PH and found their 'invisible' disease difficult to explain to others. An important finding was the secrecy surrounding PH. Feelings of insecurity and isolation were regularly reported, and many patients admitted to hiding their symptoms. The marked improvement in symptoms after therapy initiation made assessment of disease progression more difficult as patients compared their quality of life (QoL) against pretreatment levels. Extensive planning and adherence to daily routines were required in patients' everyday life. Ethnography was used for the first time, in several countries, to evaluate the patient's perception of living with PH. This approach revealed key findings that would not typically be uncovered using other qualitative techniques, including the secrecy surrounding PH, the difficulties in describing the disease and the challenges in assessing disease progression. A more tailored dissemination of information from HCPs and development of a simple and understandable PH definition may be beneficial in alleviating the secrecy reported by patients. A greater appreciation of how patients perceive their disease and QoL has the potential to improve PH management. Published by the BMJ Publishing Group Limited.

It is unclear whether the increase in life expectancy (LE) globally is coupled with a postponement of morbidity and disability. Evidence on trends and determinants of disability-free life expectancies (DFLEs) are available in high-income countries but less in low and middle-income countries (LMICs). This study examines the levels of and inequalities in LE, disability and DFLE between men and women across different age groups aged 50 years and over in six countries with developing economies. This study utilised the cross-sectional data (n=32 724) from the WHO Study on global AGEing and adult health (SAGE) in China, Ghana, India, Mexico, the Russian Federation and South Africa in 2007-2010. Disability was measured with the activity of daily living (ADL) instrument. The DFLE was estimated using the Sullivan method based on the standard period life table and ADL-disability proportions. The disability prevalence ranged from 13% in China to 54% in India. The prevalence of disability was highest and occurred at younger age in both sexes in India. Women were more disadvantaged with higher prevalence of disability across all age groups, and the situation was worst among older women in Mexico and the Russian Federation. Though women had higher LE, their proportion of remaining LE free from disability was lower than men. There are inequalities in the levels of disability and DFLE among men and women in different age groups among people aged over 50 years in these six countries. Countermeasures to decrease intercountry and gender gaps in DFLE, including improvements in health promotion and healthcare distribution, with a gender equity focus, are needed.

The global economy is changing the labour market and social protection systems in Europe. The effect of both changes on health needs to be monitored in view of an ageing population and the resulting increase in prevalence of chronic health conditions. The Spanish WORKing life Social Security (WORKss) cohort study provides unique longitudinal data to study the impact of labour trajectories and employment conditions on health, in terms of sickness absence, permanent disability and death. The WORKss cohort originated from the Continuous Working Life Sample (CWLS) generated by the General Directorate for the Organization of the Social Security in Spain. The CWLS contains a 4% representative sample of all individuals in contact with the Social Security system. The WORKss cohort exclusively includes individuals with a labour trajectory from 1981 or later. In 2004, the cohort was initiated with 1,022 ,79 Social Security members: 840,770 (82.2%) contributors and 182,009 (17.8%) beneficiaries aged 16 and older. The WORKss cohort includes demographic characteristics, chronological data about employment history, retirement, permanent disability and death. These data make possible the measurement of incidence of permanent disability, the number of potential years of working life lost, and the number of contracts and inactive periods with the Social Security system. The WORKss cohort was linked to temporary sickness absence registries to study medical diagnoses that lead to permanent disability and consequently to an earlier exit from the labour market in unhealthy conditions. Thanks to its administrative source, the WORKss cohort study will continue follow-up in the coming years, keeping the representativeness of the Spanish population affiliated to the Social Security system. The linkage between the WORKss cohort and temporary sickness absence registries is envisioned to continue. Future plans include the linkage of the cohort with mortality registries.

Given the importance of unemployment in health inequalities, re-employment of unemployed persons into paid employment may be a powerful intervention to increase population health. It is suggested that integrated programmes of vocational reintegration with health promotion may improve the likelihood of entering paid employment of long-term unemployed persons with severe mental health problems. However, the current evidence regarding whether entering paid employment of this population will contribute to a reduction in health problems remains unambiguous. This systematic review and meta-analysis aimed to assess the effects of re-employment programmes with regard to health and quality of life. Three electronic databases were searched (up to March 2015). Two reviewers independently selected articles and assessed the risk of bias on prespecified criteria. Measures of effects were pooled and random effect meta-analysis of randomised controlled trials was conducted, where possible. Sixteen studies were included. Nine studies described functioning as an outcome measure. Five studies with six comparisons provided enough information to calculate a pooled effect size of -0.01 (95% CI -0.13 to 0.11). Fifteen studies presented mental health as an outcome measure of which six with comparable psychiatric symptoms resulted in a pooled effect size of 0.20 (95% CI -0.23 to 0.62). Thirteen studies described quality of life as an outcome measure. Seven of these studies, describing eight comparisons, provided enough information to calculate a pooled effect size of 0.28 (95% CI 0.04 to 0.52). Re-employment programmes have a modest positive effect on the quality of life. No evidence was found for any effect of these re-employment programmes on functioning and mental health.

To identify the combination of factors most protective of developmental delay at age 2 among children exposed to poor maternal mental health. Observational cohort study. Pregnant women were recruited from primary healthcare offices, the public health laboratory service and community posters in Calgary, Alberta, Canada. 1596 mother-child dyads who participated in the All Our Babies study and who completed a follow-up questionnaire when their child was 2 years old. Among participants who completed the 2-year questionnaire and had complete mental health data (n=1146), 305 women (27%) were classified as high maternal mental health risk. Child development at age 2 was described and a resilience analysis was performed among a subgroup of families at maternal mental health risk. The primary outcome was child development problems. Protective factors were identified among families at risk, defined as maternal mental health risk, a composite measure created from participants' responses to mental health life course questions and standardised mental health measures. At age 2, 18% of children were classified as having development problems, 15% with behavioural problems and 13% with delayed social-emotional competencies. Among children living in a family with maternal mental health risk, protective factors against development problems included higher social support, higher optimism, more relationship happiness, less difficulty balancing work and family responsibilities, limiting the child's screen time to <1 hour per day and the child being able to fall asleep in <30 min and sleeping through the night by age 2. Among families where the mother has poor mental health, public health and early intervention strategies that support interpersonal relationships, social support, optimism, work-life balance, limiting children's screen time and establishing good sleep habits in the child's first 2 years show promise to positively influence early child development.

Evolution of organogenesis and the origin of altriciality in mammals.
Werneburg, Ingmar; Laurin, Michel; Koyabu, Daisuke; Sánchez-Villagra, Marcelo R
2016-07-01
Mammals feature not only great phenotypic disparity, but also diverse growth and life history patterns, especially in maturity level at birth, ranging from altriciality to precocity. Gestation length, morphology at birth, and other markers of life history are fundamental to our understanding of mammalian evolution. Based on the first synthesis of embryological data and the study of new ontogenetic series, we reconstructed estimates of the ancestral chronology of organogenesis and life-history modes in placental mammals. We found that the ancestor of marsupial and placental mammals was placental-like at birth but had a long, marsupial-like infancy. We hypothesize that mammalian viviparity might have evolved in association with the extension of growth after birth, enabled through lactation, and that mammalian altriciality is inherited from the earliest amniotes. The precocial lifestyle of extant sauropsids and that of many placental mammals were acquired secondarily. We base our conclusions on the best estimates and provide a comprehensive discussion on the methods used and the limitations of our dataset. We provide the most comprehensive embryological dataset ever published, "rescue" old literature sources, and apply available methods and illustrate thus an approach on how to investigate comparatively organogenesis in macroevolution. © 2016 Wiley Periodicals, Inc.

Introduction From the most recent systematic revision of the literature, an orthotopic neobladder would seem to show marginally better health related quality of life (HR-QoL) scores compared with an ileal conduit. The aim of this study was to review all relevant published studies about the comparison between ileal orthotopic neobladder (IONB) and ileal conduit using validated HR-QoL questionnaires. Materials and Methods Studies were identified by searching multiple literature databases. Data were synthesized using meta-analytic methods conformed to the PRISMA statement. Results The literature search identified 10 papers; pooled effect sizes of combined quality of life outcomes for ileal conduit versus IONB showed a significantly better HR-QoL in patients with IONB (Hedges' g = 0.278; p = 0.000);. The present study has an important limitation due to the type of the analyzed comparative studies, all retrospective and not randomized. Conclusion This meta-analysis of not-randomized, retrospective comparative studies on the impact of ileal conduit versus IONB on HR-QoL showed a significant advantage of IONB subgroups. PMID:28785189

Patients undergoing radiation therapy for the head and neck are susceptible to a significant and often abrupt deterioration in their oral health. The oral morbidities of radiation therapy include but are not limited to an increased susceptibility to dental caries and periodontal disease. They also include profound and often permanent functional and sensory changes involving the oral soft tissue. These changes range from oral mucositis experienced during and soon after treatment, mucosal opportunistic infections, neurosensory disorders, and tissue fibrosis. Many of the oral soft tissue changes following radiation therapy are difficult challenges to the patients and their caregivers and require life-long strategies to alleviate their deleterious effect on basic life functions and on the quality of life. We discuss the presentation, prognosis, and management strategies of the dental structure and oral soft tissue morbidities resulting from the administration of therapeutic radiation in head and neck patient. A case for a collaborative and integrated multidisciplinary approach to the management of these patients is made, with specific recommendation to include knowledgeable and experienced oral health care professionals in the treatment team. © 2017 The Authors.

Status of nuclear Class 1 component requalification: Final report
DOE Office of Scientific and Technical Information (OSTI.GOV)
Cooper, W.E.
1986-12-01
Qualification relates to assurance of acceptability of the component with respect to structural integrity, operability and functional capability. Requalification is required if existing qualification is lost because of: expiration of the qualified service life (life extension); reactivation of a cancelled or suspended plant; failure to conform with certain requirements of the Technical Specifications, or revision to the applicable Regulatory requirements. The alternatives to requalification are replacement or removal from service. The choice between requalification, replacement and removal from service is governed by economics. The purpose of requalification standards is to ensure the acceptability of the requalification process. A previous EPRImore » Report prepared by Teledyne Engineering Services (TES) (NP-1921) developed a rationale for, and a draft of, a generic requalification standard for Class 1 Pressure Boundary Components presently considered by the Boiler and Pressure Vessel Code published by The American Society of Mechanical Engineers (ASME/BPVC). International Energy Associates Limited (IEA) prepared another report for EPRI shortly thereafter (NP-2418), which reviewed the economic and technologies factors of nuclear plant life extension, and concluded that NP-1921 makes a strong case that the nuclear industry will benefit from the development of the proposed standard.« less
Neural predictors of emotional inertia in daily life.
Waugh, Christian E; Shing, Elaine Z; Avery, Bradley M; Jung, Youngkyoo; Whitlow, Christopher T; Maldjian, Joseph A
2017-09-01
Assessing emotional dynamics in the brain offers insight into the fundamental neural and psychological mechanisms underlying emotion. One such dynamic is emotional inertia-the influence of one's emotional state at one time point on one's emotional state at a subsequent time point. Emotion inertia reflects emotional rigidity and poor emotion regulation as evidenced by its relationship to depression and neuroticism. In this study, we assessed changes in cerebral blood flow (CBF) from before to after an emotional task and used these changes to predict stress, positive and negative emotional inertia in daily life events. Cerebral blood flow changes in the lateral prefrontal cortex (lPFC) predicted decreased non-specific emotional inertia, suggesting that the lPFC may feature a general inhibitory mechanism responsible for limiting the impact that an emotional state from one event has on the emotional state of a subsequent event. CBF changes in the ventromedial prefrontal cortex and lateral occipital cortex were associated with positive emotional inertia and negative/stress inertia, respectively. These data advance the blossoming literature on the temporal dynamics of emotion in the brain and on the use of neural indices to predict mental health-relevant behavior in daily life. © The Author (2017).

Optimization of protein and peptide drugs based on the mechanisms of kidney clearance.
Huang, Jiaguo; Wu, Huizi
2018-05-30
Development of proteins and peptides into drugs has been considered as a promising strategy to target certain diseases. However, only few proteins and peptides has been approved as new drugs into the market each year. One major problem is that proteins and peptides often exhibit short plasma half-life times, which limits the application for their clinical use. In most cases a short half-life time is not effective to deliver sufficient amount of drugs to the target organs and tissues, which is generally caused by fast renal clearance and low plasma stability due to proteolytic degradation during systemic circulation, because the most common clearance pathway of small proteins and peptides is through glomerular filtration by the kidneys. In this review, enzymatic degradation of proteins and peptides were discussed. Furthermore, several approaches to lengthen the half-life of peptides and proteins drugs based on the unique structures of glomerular capillary wall and the mechanisms of glomerular filtration were summarized, such as increasing the size and hydrodynamic diameter; increasing the negative charge to delay the filtration; increasing plasma protein binding to decrease plasma clearance.

Cancer end-of-life care and associated racial-ethnic disparities have been in focus during the last few years due to concerns regarding subjective care variations and poor quality of care. Given the high mortality rate and disease burden of lung cancer, end-of-life care quality is particularly crucial for this disease. This study uses previously validated measures and examines racial-ethnic disparities in lung cancer end-of-life care quality. This study involves retrospective analysis of patients ≥66 years, who were diagnosed with stage I-IV lung cancer, and who died on or before December 31, 2013, using the Surveillance Epidemiology and End Result-Medicare data from 1991-2013. Poor quality of care was measured using three themes: (1) potentially preventable medical encounters, (2) delayed hospice referral, and (3) aggressive chemotherapy provision during end-of-life. The patients were analyzed as two separate cohorts of NSCLC and SCLC patients. Logistic regression analyses were performed to estimate racial-ethnic disparities in the adjusted odds of receiving poor quality end-of-life care. The study found considerable racial-ethnic disparities in end-of-life care quality. The racial-ethnic minorities had higher odds of experiencing potentially preventable medical encounters in the last month of life as compared with non-Hispanic whites. Odds of delayed hospice referral and aggressive chemotherapy provision during end-of-life were lower in non-Hispanic blacks as compared with non-Hispanic whites. The study findings highlight the continued lack of access and care disparity among the minorities, which could precipitate potentially preventable utilizations, and limit access to hospice care during end-of-life. The study suggests the need to develop educational, patient navigational and other interventions that could potentially reduce aggressive utilizations and improve appropriate hospice care provision during end-of-life.

To clarify the relationship between masticatory performance and oral health-related quality of life (OHRQoL) before and after complete denture treatment. Thirty patients wearing complete dentures were asked to chew a gummy jelly on their habitual chewing side, and the amount of glucose extraction during chewing was measured as the parameter of masticatory performance. Subjects were asked to answer the Oral Health Impact Profile (OHIP-J49) questionnaire, which consists of 49 questions related to oral problems. The total score of 49 question items along with individual domain scores within the seven domains (functional limitation, pain, psychological discomfort, physical disability, psychological disability, social disability and handicap) were calculated and used as the parameters of OHRQoL. These records were obtained before treatment and 3 months after treatment. Each parameter of masticatory performance and OHRQoL was compared before treatment and after treatment. The relationship between masticatory performance and OHRQoL was investigated, and a stepwise multiple linear regression analysis was performed. Both masticatory performance and OHRQoL were significantly improved after treatment. Furthermore, masticatory performance was significantly correlated with some parameters of OHRQoL. The stepwise multiple linear regression analysis showed functional limitation and pain as important factors affecting masticatory performance before treatment and functional limitation as important factors affecting masticatory performance after treatment. These results suggested that masticatory performance and OHRQoL are significantly improved after treatment and that there is a close relationship between the two. Moreover, functional limitation was found to be the most important factor affecting masticatory performance. Copyright © 2018 Japan Prosthodontic Society. Published by Elsevier Ltd.

An immediate decrease in the total antioxidant activity (23%) and total phenolic content (14%) was observed after addition of strawberry preparations to yoghurt. The total anthocyanin content did not change immediately, but decreased 24% throughout the yoghurt shelf-life. The individual compounds, (+)-catechin (60%), (-)-epicatechin (60%), kaempferol (33%) and quercetin-3-rutinoside (29%) decreased after 24h in the yoghurt made with the strawberry preparation. During the remaining period of storage these compounds increased by 47%, 6%, 4% and 18%, respectively. Pelargonidin-3-glucoside decreased 49% after 28 d. Immediately after the addition of the strawberry preparation to yoghurt, β-lactoglobulin decreased to values lower than the limit of detection and α-lactalbumin by approximately 34%, and was reduced further slowly throughout yoghurt self-life. An immediate interaction between the carrageenan present in the strawberry preparation and β-LG was observed. The variations of both polyphenols and protein in the presence of carrageenan and the potential interactions were discussed. Copyright © 2014. Published by Elsevier Ltd.

American Indians/Alaska Natives (AIs/ANs) have higher rates of chronic illness and lack access to palliative/end-of-life (EOL) care. This integrative review ascertained the state of the science on culturally acceptable palliative/EOL care options for Indigenous persons in the United States. Databases searched: CINAHL, PubMed/MEDLINE, SocINDEX, PsycINFO, PsycARTICLES, ERIC, Health Source: Nursing/Academic Edition, and EBSCO Discovery Service 1880s-Present. Key terms used: palliative care, EOL care, and AI/AN. peer-reviewed articles published in English. Findings/Results: Twenty-nine articles were identified, 17 remained that described culturally specific palliative/EOL care for AIs/ANs. Synthesis revealed four themes: Communication, Cultural Awareness/Sensitivity, Community Guidance for Palliative/EOL Care Programs, Barriers and two subthemes: Trust/Respect and Mistrust. Limitations are lack of research funding, geographic isolation, and stringent government requirements. Palliative/EOL care must draw on a different set of skills that honor care beyond cure provided in a culturally sensitive manner.
Quality of work life, burnout, and stress in emergency department physicians: a qualitative review.
Bragard, Isabelle; Dupuis, Gilles; Fleet, Richard
2015-08-01
A 2006 literature review reported that emergency department (ED) physicians showed elevated burnout levels and highlighted several environment and personal issues contributing toward burnout. Research on burnout in EDs is limited. We propose an updated qualitative review on the relationships between work stress, burnout, and quality of work life in ED physicians. We searched MEDLINE, PsycInfo, and Science Direct for studies published since 2005. Of 491 papers, 10 papers were retained, using validated measures and having a minimum of 75 participants. Data extraction was performed manually by the first author and was reviewed by the second author. The majority of the studies used large samples, cross-sectional designs, random, and/or stratified assignment. ED physicians showed moderate to high levels of burnout with difficult work conditions including significant psychological demands, lack of resources, and poor support. Nonetheless, physicians reported high job satisfaction. Further studies should focus on the implementation of measures designed to prevent burnout.
Physiotherapy management of lower limb osteoarthritis.
Walsh, Nicola E; Pearson, Jennifer; Healey, Emma L
2017-06-01
Osteoarthritis (OA) of the lower limb affects millions of people worldwide, and results in pain and reduced function. We reviewed guidelines and Cochrane reviews for physical therapy interventions to manage the condition. Evidence from meta-analyses and systematic reviews was included. We also identified the recommendations from guidelines relevant to practice in the UK. There is strongest evidence to support the use of exercise to improve pain, function and quality of life. There is limited evidence to support the use of some commonly utilized physiotherapy interventions. National Institute for Health and Clinical Excellence do not recommend the use of acupuncture. Programmes that include single exercise type may be more beneficial than combined strengthening and aerobic interventions. Further research is required to determine how to facilitate long-term engagement with exercise to sustain the beneficial effects on pain, function and quality of life. Studies that investigate packages of care, combining interventions require further investigation. © The Author 2017. Published by Oxford University Press. All rights reserved.

Idiopathic pulmonary fibrosis is defined as a chronic fibrosing interstitial pneumonia limited to the lung, of unknown cause, with poor prognosis and few treatment options. In recent years there has been an increase in their prevalence, probably due to the optimization of diagnostic methods and increased life expectancy. The ATS/ERS Consensus (2000) established the diagnostic criteria and recommendations for the assessment of the disease course and treatment. Later studies have helped to redefine diagnostic criteria and treatment options. In 2011, an international consensus was published, establishing diagnostic criteria and new treatment strategies. These guidelines have been updated with the newest aspects of diagnosis and treatment of idiopathic pulmonary fibrosis. A level of evidence has been identified for the most relevant questions, particularly with regard to treatment options. Copyright © 2012 SEPAR. Published by Elsevier Espana. All rights reserved.

Lateral ankle sprains (LASs) are the most prevalent musculoskeletal injury in physically active populations. They also have a high prevalence in the general population and pose a substantial healthcare burden. The recurrence rates of LASs are high, leading to a large percentage of patients with LAS developing chronic ankle instability. This chronicity is associated with decreased physical activity levels and quality of life and associates with increasing rates of post-traumatic ankle osteoarthritis, all of which generate financial costs that are larger than many have realised. The literature review that follows expands this paradigm and introduces emerging areas that should be prioritised for continued research, supporting a companion position statement paper that proposes recommendations for using this summary of information, and needs for specific future research.

Electrical Stimulation and Swallowing: How Much Do We Know?
Humbert, Ianessa A.; Michou, Emilia; MacRae, Phoebe R.; Crujido, Lisa
2012-01-01
Consequences of dysphagia substantially reduce quality of life, increase the risk of medical complications and mortality, and pose a substantial cost to healthcare systems. As a result, it is of no wonder that the clinical and scientific communities are showing interest in new avenues for dysphagia rehabilitation. Electrical stimulation (e-stim) for the treatment of swallowing impairments is among the most studied swallowing interventions in the published literature, yet many unanswered questions about its efficacy remain. In the meantime, many speech-language pathologists who treat dysphagia are attending educational and training sessions to obtain certifications to use this technique. Here, we review the values and limitations of the published literature on the topic of e-stim for swallowing to assist clinicians in decision making in their clinical practice. The discussion provides a review of swallowing anatomy and physiology, the fundamentals of e-stim, and information essential for the readers’ independent critique of these studies—all of which are crucial for evaluating the possible effects of e-stim.

Urea cycle disorders: a life-threatening yet treatable cause of metabolic encephalopathy in adults.
Blair, Nicholas F; Cremer, Philip D; Tchan, Michel C
2015-02-01
Urea cycle disorders are inborn errors of metabolism that, in rare cases, can present for the first time in adulthood. We report a perplexing presentation in a woman 4 days postpartum of bizarre and out-of-character behaviour interspersed with periods of complete normality. Without any focal neurological signs or abnormality on initial investigations, the diagnosis became clear with the finding of a significantly elevated plasma ammonia level, just as she began to deteriorate rapidly. She improved following intravenous dextrose and lipid emulsion, together with sodium benzoate, arginine and a protein-restricted diet. She remains well 12 months later with no permanent sequelae. Whilst this is a rare presentation of an uncommon disease, it is a treatable disorder and its early diagnosis can prevent a fatal outcome. Published by the BMJ Publishing Group Limited.

Sir William Osler meticulously described the clinical manifestations of infective endocarditis in 1885, concluding that: 'few diseases present greater difficulties in the way of diagnosis … which in many cases are practically insurmountable'. Even with modern investigation techniques, diagnosing infective endocarditis can be hugely challenging, yet is critically important in patients presenting with stroke (both cerebral infarction and intracranial haemorrhage), its commonest neurological complication. In ischaemic stroke, intravenous thrombolysis carries an unacceptably high risk of intracranial haemorrhage, while in intracerebral haemorrhage, mycotic aneurysms require urgent treatment to avoid rebleeding, and in all cases, prompt treatment with antibiotics and valve surgery may be life-saving. Here, we describe typical presentations of ischaemic stroke and intracerebral haemorrhage caused by infective endocarditis. We review the diagnostic challenges, the importance of rapid diagnosis, treatment options and controversies. Published by the BMJ Publishing Group Limited.

Each year, at least 280,000 children are born with sickle cell disease (SCD) in resource-limited settings. For cost, logistic and political reasons, the availability of SCD testing is limited in such settings and consequently 50-90 % of affected children die undiagnosed before their fifth birthday. The recent development of a point of care method for the diagnosis of SCD - the Sickle SCAN™ device - could afford such children the prompt access to appropriate services that has transformed the outlook for affected children in resource-rich areas. In research published in BMC Medicine, Kanter and colleagues describe a small but carefully conducted study involving 208 children and adults, in which they found that by using Sickle SCAN™ it was possible to diagnose the common forms of SCD with 99 % sensitivity and 99 % specificity, in under 5 minutes. If repeatable both in newborn babies and under real-life conditions, and if marketed at an affordable price, Sickle SCAN™ could revolutionize the survival prospects for children born with SCD in resource-limited areas.Please see related article: http://dx.doi.org/10.1186/s12916-015-0473-6.

Smokers and nonsmokers can encounter a variety of antismoking messages in their everyday life. Antismoking warnings often involve fear appeals to which particularly smokers may react in a defensive manner by avoiding or derogating the messages, or downplaying their personal risk. However, previous studies testing the effects of antismoking warnings have either been retrospective or lab-based, thus introducing potential recall biases and yielding limited ecological validity. We used ecological momentary assessment (EMA) to give an overview on the number, type, and locations where individuals encounter such messages and to examine their immediate reactions. In an EMA study, 33 smokers and 37 never-smokers logged every encounter with antismoking warnings during 2.5 weeks (1,237 participant days of monitoring). After randomly selected encounters, several markers of defensiveness were assessed. On average, nonsmokers reported noticing significantly fewer warnings than smokers (M = 0.49/day vs. M = 2.14/day). Both groups saw the majority of warnings on cigarette packages. Smokers reported a significantly higher level of message derogation and a significantly lower level of message acceptance than nonsmokers. There were no differences in feelings of vulnerability between smokers and nonsmokers upon encountering the warnings. The overall number of encounters with antismoking warnings in people's everyday life is relatively low, particularly among smokers. Smokers are likely to avoid messages and respond defensively, thus limiting their potential effectiveness. © The Author 2014.

Historically, palliative care has been developed for cancer patients and is not yet generally available for patients suffering from chronic life-limiting illnesses, such as chronic obstructive pulmonary disease (COPD). To examine whether COPD patients experience similar or worse disease burden in comparison with non-small cell lung cancer (NSCLC) patients, we compared the health-related quality of life (HRQOL) scores of severe COPD patients with those of advanced NSCLC patients. We also formally updated previous evidence in this area provided by a landmark study published by Gore et al. in 2000. In updating this previous evidence, we addressed the methodological limitations of this study and a number of confounding variables. Eighty-two GOLD IV COPD patients and 19 Stage IIIb or IV NSCLC patients completed generic and disease-specific HRQOL questionnaires. We used an individual patient data meta-analysis to integrate the new and existing evidence (total n=201). Finally, to enhance between-group comparability, we performed a sensitivity analysis using a subgroup of patients with a similar degree of "terminality," namely those who had died within one year after study entry. Considerable differences in HRQOL were found for physical functioning, social functioning, mental health, general health perceptions, dyspnea, activities of daily living, and depression. All differences favored the NSCLC patients. The sensitivity analysis, using only terminal NSCLC and COPD patients, confirmed these findings. In conclusion, end-stage COPD patients experience poor HRQOL comparable to or worse than that of advanced NSCLC patients. We discuss these findings in the light of the notion that these COPD patients may have a similar need for palliative care.

: Ageing, death, dying and loss are universal issues that have a range of health, wellbeing, financial and socio-economic costs for society. The End of Life Partnership (EoLP) is a charitable collaborative in Cheshire, which aims to transform end of life experience and care, by working with a wide range partners from the public, private and third sectors and by engaging individuals, families and communities. Launched in April 2014, the EoLP merged three existing programmes focussing on public health, education and service development and added an additional research focus. There are now four dedicated departments: Public Health and Wellbeing; Research, Evaluation and Technology; Service Development; Education and Practice Development. In October 2014 a Dementia work stream was added. The work of The EoLP is shaped, overseen and monitored by a Strategic Partnership Executive, with representation from key local stakeholders and a board of trustees. The EoLP meets national objectives and delivers on local priorities agreed with stakeholders, including patients and the public. This is strengthened through a dedicated Cheshire Living Well, Dying Well Partnership to enable community voices to be heard. Significant milestones have already been realised as a partnership collaborative. For example, response to the national review of the Liverpool Care Pathway incorporated development of a local care plan with stakeholders, educational strategy to ensure effective roll-out, public consultation and work to measure impact. The EoLP works to influence and shape policy and practice at a local, regional, national and international level. © 2015, Published by the BMJ Publishing Group Limited.

QALYs, euthanasia and the puzzle of death.
Barrie, Stephen
2015-08-01
This paper considers the problems that arise when death, which is a philosophically difficult concept, is incorporated into healthcare metrics, such as the quality-adjusted life year (QALY). These problems relate closely to the debate over euthanasia and assisted suicide because negative QALY scores can be taken to mean that patients would be 'better off dead'. There is confusion in the literature about the meaning of 0 QALY, which is supposed to act as an 'anchor' for the surveyed preferences on which QALYs are based. In the context of the debate over euthanasia, the QALY assumes an ability to make meaningful comparisons between life-states and death. Not only is this assumption questionable, but the ethical debate is much more broad than the question of whether death is preferable to a state of living. QALYs are derived from preferences about health states, so do not necessarily reflect preferences about events (eg, dying) or actions (eg, killing). This paper presents a new kind of problem for the QALY. As it stands, the QALY provides confused and unreliable information when it reports zero or negative values, and faces further problems when it appears to recommend death. This should preclude its use in the debate over euthanasia and assisted suicide. These problems only apply where the QALY involves or seems to involve a comparison between life-states and death, and are not relevant to the more general discussion of the use of QALYs as a tool for comparing the benefits derived from treatment options.

To investigate pain, activities of daily living (ADL) function, sport function, quality of life and satisfaction at different time points after hip arthroscopy in patients with femoroacetabular impingement (FAI). Systematic review with meta-analysis. Weighted mean differences between preoperative and postoperative outcomes were calculated and used for meta-analysis. EMBASE, MEDLINE, SportsDiscus, CINAHL, Cochrane Library, and PEDro. Studies that evaluated hip pain, ADL function, sport function and quality of life before and after hip arthroscopy and postoperative satisfaction in patients with symptomatic FAI. Twenty-six studies (22 case series, 3 cohort studies, 1 randomised controlled trial (RCT)) were included in the systematic review and 19 in the meta-analysis. Clinically relevant pain and ADL function improvements were first reported between 3 and 6 months, and sport function improvements between 6 months and 1 year after surgery. It is not clear when quality of life improvements were first achieved. On average, residual mild pain and ADL and sport function scores lower than their healthy counterparts were reported by patients following surgery. Postoperative patient satisfaction ranged from 68% to 100%. On average, patients reported earlier pain and ADL function improvements, and slower sport function improvements after hip arthroscopy for FAI. However, average scores from patients indicate residual mild hip pain and/or hip function lower than their healthy counterparts after surgery. Owing to the current low level of evidence, future RCTs and cohort studies should investigate the effectiveness of hip arthroscopy in patients with FAI. CRD42015019649.

Young people are often denied volunteering experiences with vulnerable dying people as this is considered to be 'too distressing'. This project challenged this paternalistic attitude and trained young people to volunteer in the hospice, and other organisations to enhance the delivery of compassionate care. To promote dignity in care, for older people, people with dementia, those at end of life and those with learning disabilities. To reduce social isolation and the stigma associated with dying and being old. To create new volunteering opportunities for young people to raise their awareness of the needs of the dying and the frail elderly. Develop a model of best practice - that could be replicated in other parts of the country. A health promotion approach was used combining education and a community development, partnership approach. Results 120 Volunteers delivered over 3,650 hrs of volunteering activities, supporting individuals to engage in social activities. The project broke myths about having 16-18 year olds volunteering. The relationship between the hospice and the local community has strengthened and the employability skills for the young people taking part have increased. 16% of those who responded to an exit survey had gained full time employment, 9% had gained university places. The personalisation of care for the frail elderly and those at end of life has increased by the use of volunteers. Young volunteers need mentoring. Staff needs support to feel confident to utilise the volunteers and let go of myths about risks. © 2015, Published by the BMJ Publishing Group Limited.

Wealth, income, and health before and after retirement.
Geyer, Siegfried; Spreckelsen, Ove; von dem Knesebeck, Olaf
2014-11-01
It was supposed that associations of wealth and health might be higher after retirement than in the economically active periods of life, but no comparisons were available. Most studies on wealth were based on net worth, a measure combining several elements of wealth into an index. We examined associations between different elements of wealth and health by comparing retired women and men with economically active ones. Data were drawn from the German Socio-Economic Panel, a nationwide longitudinal survey project. Two waves (2002 and 2007) included indicators of wealth in addition to household income and education. Wealth was not depicted by an index. Instead, debts, property of life insurances, home ownership and assets were considered separately with their associations with self-rated health. Two data sets were used to examine whether the results were occasional, or whether they can be replicated. Associations of income and education emerged in respondents in their active periods of life. In most cases indicators of wealth were associated with subjective health. In retired respondents home ownership was the only indicator yielding consistent associations with health, but their sizes turned out as rather moderate. Contrary to expectation, the associations of wealth and health were inconsistent in the retired study population. These results were obtained in a country with national pension schemes, and it has to be examined whether the findings can be generalised to other countries. The inconsistent findings of indicators of wealth are calling the utility of net worth into question. Published by the BMJ Publishing Group Limited.

To assess the cost-effectiveness of an educational intervention encouraging self-skin examinations for early detection of skin cancers among men older than 50 years. A lifetime Markov model was constructed to combine data from the Skin Awareness Trial and other published sources. The model incorporated a health system perspective and the cost and health outcomes for melanoma, squamous and basal cell carcinomas, and benign skin lesions. Key model outcomes included Australian costs (2015), quality-adjusted life-years (QALYs), life-years, and counts of skin cancers. Univariate and probabilistic sensitivity analyses were undertaken to address parameter uncertainty. The mean cost of the intervention was A$5,298 compared with A$4,684 for usual care, whereas mean QALYs were 7.58 for the intervention group and 7.77 for the usual care group. The intervention was thus inferior to usual care. When only survival gain is considered, the model predicted the intervention would cost A$1,059 per life-year saved. The likelihood that the intervention was cost-effective up to A$50,000 per QALY gained was 43.9%. The model was stable to most data estimates; nevertheless, it relies on the specificity of clinical diagnosis of skin cancers and is subject to limited health utility data for people with skin lesions. Although the intervention improved skin checking behaviors and encouraged men to seek medical advice about suspicious lesions, the overall costs and effects from also detecting more squamous and basal cell carcinomas and benign lesions outweighed the positive health gains from detecting more thin melanomas.

Our aim was to study associations between physical exposures throughout working life and physical function measured as chair-rise performance in midlife. The Copenhagen Aging and Midlife Biobank (CAMB) provided data about employment and measures of physical function. Individual job histories were assigned exposures from a job exposure matrix. Exposures were standardised to ton-years (lifting 1000 kg each day in 1 year), stand-years (standing/walking for 6 h each day in 1 year) and kneel-years (kneeling for 1 h each day in 1 year). The associations between exposure-years and chair-rise performance (number of chair-rises in 30 s) were analysed in multivariate linear and non-linear regression models adjusted for covariates. Mean age among the 5095 participants was 59 years in both genders, and, on average, men achieved 21.58 (SD=5.60) and women 20.38 (SD=5.33) chair-rises in 30 s. Physical exposures were associated with poorer chair-rise performance in both men and women, however, only associations between lifting and standing/walking and chair-rise remained statistically significant among men in the final model. Spline regression analyses showed non-linear associations and confirmed the findings. Higher physical exposure throughout working life is associated with slightly poorer chair-rise performance. The associations between exposure and outcome were non-linear. Published by the BMJ Publishing Group Limited.

WA3 Room for death - international museum - visitors' preferences regarding the end of their life.
Lindqvist, Olav; Tishelman, Carol
2015-04-01
Just as pain medications aim to relieve physical suffering, supportive surrounding for death and dying may facilitate well-being and comfort. However, little has been written of the experience of or preferences for settings for death and dying. We investigate preferences for and reflections about settings for end-of-life (EoL) in an international sample of museum visitors. Data derive from a project teaming artists and craftspeople together to create prototypes of space for difficult conversations in EoL settings. These prototypes were presented in a museum exhibition, "Room for Death", in Stockholm in 2012. As project consultants, we contributed a question to the public viewing the exhibition: "How would you like it to be around you when you are dying?" and analysed responses with a phenomenographic approach. Five-hundred twelve responses were obtained from visitors from 46 countries. Responses were categorised in the following inductively- derived categories of types of deaths: The "Familiar", "Larger-than life", "Lone", "Mediated" "Calm and peaceful", "Sensuous", "'Green'", and "Distanced" death. Responses could relate to one category or be composites uniting different categories in individual combinations. These data provide insight into different facets of contemporary reflections about death and dying. Despite the selective sample, the findings give reason to consider how underlying assumptions and care provision in established forms for EoL care may differ from people's preferences. This project can be seen as an example of innovative endeavours to promote public awareness of issues related to death and dying, within the framework of health-promoting palliative care. © 2015, Published by the BMJ Publishing Group Limited.

The Asthma Impact Survey (AIS-6) is a brief disease-specific quality-of-life instrument with limited published validation data. To obtain additional validation data and psychometric properties of the AIS-6. In November, 2007, patients with persistent asthma were mailed a survey that included the AIS-6, the mini-Asthma Quality of Life Questionnaire (mAQLQ), and the Asthma Control Test (ACT). Follow-up surveys were sent in April, July, and October 2008. Year 2008 exacerbations and short-acting β-agonist (SABA) dispensings were captured from administrative data. A total of 2680 patients had complete baseline survey data. Criterion validity was demonstrated by the strong correlations of the AIS-6 with the mAQLQ (r = -0.84 to -0.86); construct validity by significant relationships (P < .0001) of the AIS-6 with mAQLQ domain scores, ACT score, and history of exacerbations; and predictive validity by significant relationships (P < .0001) between AIS-6 scores at the end of 2007 and year 2008 exacerbations and high SABA dispensings. Responsiveness was demonstrated by significant (P < .0001) correlations (r = -0.39 to -0.58) between changes in AIS-6 scores and changes in mAQLQ and ACT scores over time. A preliminary minimally important difference (MID) in AIS-6 was estimated to be 4 by using the mAQLQ MID as an anchor. Excellent internal consistency (α = 0.94) and test-retest reliability (intraclass correlation coefficient = 0.86-0.91) were also demonstrated. The AIS-6 demonstrated good psychometric properties in a large independent sample and could be used to assess asthma-specific quality of life in clinical practice and clinical research.

Few studies have addressed health-related quality of life (QoL) in patients who chose conservative management over dialysis. This systematic review aims to better define the role of conservative management in improving health-related QoL in patients with end-stage renal disease (ESRD). Medline, Cochrane and EMBASE were searched for prospective or retrospective studies published until June 30, 2016, that examined QoL of ESRD patients. The primary outcome was health-related QoL. Four studies were included (405 patients received dialysis and 332 received conservative management). Two studies that used the Short Form-36 Survey (SF-36) showed that the dialysis group had higher physical component scores, but the conservative management group had similar, or better, mental component scores at the end of intervention. Another study using the SF-36 showed that the physical and mental component scores of the dialysis group did not significantly change after intervention. In the conservative management group, the physical component scores did not change, but the mental component scores increased significantly over time (0.12 ± 0.32, p < 0.05). One study, which used the Kidney Disease Quality of Life-Short Form (KD QoL-SF), found no change after intervention in either physical or mental component scores in the dialysis group; however, the physical component score declined (p = 0.047) and the mental component score increased (p = 0.033) in the conservative management group. Although there are only a limited number of published articles, ESRD patients who receive conservative management may have improved mental health-related QoL when compared with those who receive dialysis.

Fetal and postnatal growth have been associated with adult blood pressure (BP), but findings about the relative importance of growth at different stages of life on BP are inconsistent. The study population comprised 5198 participants from the Northern Finland Birth Cohort 1966 with data on birth weight, height and weight measurements until adolescence, systolic and diastolic BP at 31 years and several covariates. Structural equation modelling was used in the analysis. Negative direct effects of birth weight on adult systolic BP were observed (standardised regression coefficients: -0.08 (-0.14 to -0.03) in males and -0.04 (-0.09 to 0.01) in females, equalling -1.99 (-3.32 to -0.65) and -1.01 (-2.33 to 0.32) mm Hg/kg, respectively). Immediate postnatal growth was associated with adult BP only indirectly via growth later in life. In contrast, growth from adiposity rebound onwards had large direct, indirect and total effects on adult BP. Current body mass index was the strongest growth-related predictor of adult BP (0.36 (0.30 to 0.41) in males and 0.31 (0.24, 0.37) in females, equalling 1.29 (1.09 to 1.48) and 0.81 (0.63 to 0.99) mm Hg/(kg/m(2)), respectively). Our path analytical approach provides evidence for the importance of both fetal growth and postnatal growth, especially from adiposity rebound onwards, in determining adult BP, together with genetic predisposition and behavioural factors.

The effect of urban green on small-area (healthy) life expectancy.
Jonker, M F; van Lenthe, F J; Donkers, B; Mackenbach, J P; Burdorf, A
2014-10-01
Several epidemiological studies have investigated the effect of the quantity of green space on health outcomes such as self-rated health, morbidity and mortality ratios. These studies have consistently found positive associations between the quantity of green and health. However, the impact of other aspects, such as the perceived quality and average distance to public green, and the effect of urban green on population health are still largely unknown. Linear regression models were used to investigate the impact of three different measures of urban green on small-area life expectancy (LE) and healthy life expectancy (HLE) in The Netherlands. All regressions corrected for average neighbourhood household income, accommodated spatial autocorrelation, and took measurement uncertainty of LE, HLE as well as the quality of urban green into account. Both the quantity and the perceived quality of urban green are modestly related to small-area LE and HLE: an increase of 1 SD in the percentage of urban green space is associated with a 0.1-year higher LE, and, in the case of quality of green, with an approximately 0.3-year higher LE and HLE. The average distance to the nearest public green is unrelated to population health. The quantity and particularly quality of urban green are positively associated with small-area LE and HLE. This concurs with a growing body of evidence that urban green reduces stress, stimulates physical activity, improves the microclimate and reduces ambient air pollution. Accordingly, urban green development deserves a more prominent place in urban regeneration and neighbourhood renewal programmes. Published by the BMJ Publishing Group Limited.

Social media describes technological applications which are used to exchange information in a virtual environment. The use of social media is increasing, in professional and social contexts, on a variety of platforms such as Twitter; however, the scope and breadth of its use to discuss end-of-life care has not previously been reported. To determine the frequency, sentiment and trend of Twitter 'tweets' containing palliative care-related identifiers (hashtags) and/or phrases sent by users over a 2-year period. A 2-year retrospective analysis of Twitter posts (tweets), between the 1 August 2011 to 31 July 2013, using a social media analytics tool: TopsyPro. Thirteen search terms were identified and analysed for tweet volume, frequency, sentiment and acceleration. A total of 683.5K tweets containing a combination of 13 palliative care terms were analysed. The tweet volume for all terms increased by 62.3% between 2011-2012 (262.5K) and 2012-2013 (421K). The most popular terms include 'end-of-life' (210K), #hpm (114K) and 'palliative care' (93.8K). Sentiment was high with 89% of tweets rated more positive than all other tweets sent on Twitter during this period. The term 'Liverpool Care Pathway' experienced the highest percentage increase in tweets (55% increase) reaching a peak in July 2013. A lot of discussion about palliative care is taking place on Twitter, and the majority of this is positive. Social media presents a novel opportunity for engagement and ongoing dialogue with public and professional groups. Published by the BMJ Publishing Group Limited.

To determine the views and experiences of health and social care professionals on using integrated care pathways (ICPs)for caring for people in the last days to hours of life. Online cross-sectional questionnaire survey of UK professionals working in UK primary and secondary care settings. 1331 professionals returned completed questionnaires. Ninety-three per cent (1138/1228) of respondents used the Liverpool Care Pathway (LCP) or local variant. Eighty-eight (1089/1234) felt ICPs enabled professionals to provide better care for individuals and their families/carers. ICPs were viewed as promoting patient-centred holistic care, improving pain and symptom control, providing guidance and standards and improving communication with patients/families. Sixty-two per cent (770/1234) had no concerns regarding the use of ICPs. Areas of concern included incorrect use and implementation of the ICP, poor communication with families, junior level staff making decisions and insufficient education and support. There was strong support for using ICPs for caring for people in the last days to hours of life. ICPs were viewed as supporting high-quality patient-centred holistic care. Given the recommendations of the More Care Less Pathway report, those that develop the guidance and support that replace the LCP need to incorporate the aspects of this that have resulted in the benefits seen by professionals within this survey, but also learn from the instances where ICPs have failed to prevent poor care, or worse, have contributed to it.

The life course perspective suggests a pathway may exist among maternal exposure to stressful life events prior to conception (PSLEs), infant birth weight and subsequent offspring health, whereby PSLEs are part of a 'chains-of-risk' that set children on a certain health pathway. No prior study has examined the link between PSLEs and offspring health in a nationally representative sample of US mothers and their children. We used longitudinal, nationally representative data to evaluate the relation between maternal exposure to PSLEs and subsequent measures of infant and toddler health, taking both maternal and obstetric characteristics into account. We examined 6900 mother-child dyads participating in 2 waves of the nationally representative Early Childhood Longitudinal Study-Birth Cohort (n=6900). Infant and toddler health outcomes assessed at 9 and 24 months included overall health status, special healthcare needs and severe health conditions. Adjusted path analyses examined associations between PSLEs, birth weight and child health outcomes. In adjusted analyses, PSLEs increased the risk for very low birth weight (VLBW, <1500 g), which, in turn, predicted poor health at both 9 and 24 months of age. Path analyses demonstrated that PSLEs had small indirect effects on children's subsequent health that operated through VLBW. Our analysis suggests a chains-of-risk model in which women's exposure to PSLEs increases the risk for giving birth to a VLBW infant, which, in turn, adversely affects infant and toddler health. Addressing women's preconception health may have important downstream benefits for their children, although more research is needed to replicate these findings.

People living and dying with non-cancer diagnoses, including dementia, have poorer access to generalist and specialist palliative care than people with cancer, and experience worse outcomes in terms of pain and symptom control, and quality and experience of care. In the UK, the National Council for Palliative Care (NCPC) ran a national survey of services for end-of-life care for people with dementia (2008) in which 16 services were identified, and reported on case studies and examples of good practice. We updated the NCPC survey to review progress in previously identified services, identify factors that lead to sustainable services and identify new initiatives in this area of care. An online survey was developed and piloted before use. Initiatives were contacted via targeted (N=63) and open call invitations. The survey was made up of 5 sections. Quantitative data were analysed using descriptive statistics. 15 services responded. They engaged in a wide range of activities predominately providing direct care (80%) and workforce development/advisory or educational activities (87%). Results suggest that sustainability of services is reliant on clinicians with a leadership role and wider system support through funding mechanisms and a minimum level of integration within normal service provision. Recent initiatives are largely built on the expertise of the nursing profession (with or without input from medical consultants), and driven mainly by the charity and hospice sector. This has generated a potential new model of care provision in end of life dementia care, 'Hospice-enabled Dementia Care'. Published by the BMJ Publishing Group Limited.

Cost-effectiveness of supervised exercise therapy in heart failure patients.

2011-01-01
Exercise therapy in heart failure (HF) patients is considered safe and has demonstrated modest reduction in hospitalization rates and death in recent trials. Previous cost-effectiveness analysis described favorable results considering long-term supervised exercise intervention and significant effectiveness of exercise therapy; however, these evidences are now no longer supported. To evaluate the cost-effectiveness of supervised exercise therapy in HF patients under the perspective of the Brazilian Public Healthcare System. We developed a Markov model to evaluate the incremental cost-effectiveness ratio of supervised exercise therapy compared to standard treatment in patients with New York Heart Association HF class II and III. Effectiveness was evaluated in quality-adjusted life years in a 10-year time horizon. We searched PUBMED for published clinical trials to estimate effectiveness, mortality, hospitalization, and utilities data. Treatment costs were obtained from published cohort updated to 2008 values. Exercise therapy intervention costs were obtained from a rehabilitation center. Model robustness was assessed through Monte Carlo simulation and sensitivity analysis. Cost were expressed as international dollars, applying the purchasing-power-parity conversion rate. Exercise therapy showed small reduction in hospitalization and mortality at a low cost, an incremental cost-effectiveness ratio of Int$26,462/quality-adjusted life year. Results were more sensitive to exercise therapy costs, standard treatment total costs, exercise therapy effectiveness, and medications costs. Considering a willingness-to-pay of Int$27,500, 55% of the trials fell below this value in the Monte Carlo simulation. In a Brazilian scenario, exercise therapy shows reasonable cost-effectiveness ratio, despite current evidence of limited benefit of this intervention.

End-of-life care (EoLC) communication skills training for generalist palliative care providers is recommended in policy guidance globally. Although many training programs now exist, there has been no comprehensive evidence synthesis to inform future training delivery and evaluation. To identify and appraise how EoLC communication skills training interventions for generalist palliative care providers are developed, delivered, evaluated, and reported. Systematic review. Ten electronic databases (inception to December 2015) and five relevant journals (January 2004 to December 2015) were searched. Studies testing the effectiveness of EoLC communication skills training for generalists were included. Two independent authors assessed study quality. Descriptive statistics and narrative synthesis are used to summarize the findings. From 11,441 unique records, 170 reports were identified (157 published, 13 unpublished), representing 160 evaluation studies of 153 training interventions. Of published papers, eight were of low quality, 108 medium, and 41 high. Few interventions were developed with service user involvement (n = 7), and most were taught using a mixture of didactics (n = 123), reflection and discussion (n = 105), and role play (n = 86). Evaluation designs were weak: <30% were controlled, <15% randomized participants. Over half (n = 85) relied on staff self-reported outcomes to assess effectiveness, and 49% did not cite psychometrically validated measures. Key information (e.g., training duration, participant flow) was poorly reported. Despite a proliferation of EoLC communication skills training interventions in the literature, evidence is limited by poor reporting and weak methodology. Based on our findings, we present a CONSORT statement supplement to improve future reporting and encourage more rigorous testing. Copyright © 2017 The Author(s). Published by Elsevier Inc.

2016-11-01
For patients with pharmacoresistant focal epilepsy in whom surgical resection of the epileptogenic focus fails or was not feasible in the first place, there were few therapeutic options. Increasingly, neurostimulation provides an alternative treatment strategy for these patients. Vagal nerve stimulation (VNS) is well established. Deep brain stimulation (DBS) and cortical responsive stimulation (CRS) are newer neurostimulation therapies with recently published long-term efficacy and safety data. In this literature review, we introduce these therapies to a non-specialist audience. Furthermore, we compare and contrast long-term (5-year) outcomes of newer neurostimulation techniques with the more established VNS. A search to identify all studies reporting long-term efficacy (>5 years) of VNS, CRS and DBS in patients with refractory focal/partial epilepsy was conducted using PubMed and Cochrane databases. The outcomes compared were responder rate, percentage seizure frequency reduction, seizure freedom, adverse events, neuropsychological outcome and quality of life. We identified 1 study for DBS, 1 study for CRS and 4 studies for VNS. All neurostimulation technologies showed long-term efficacy, with progressively better seizure control over time. Sustained improvement in quality of life measures was demonstrated in all modalities. Intracranial neurostimulation had a greater side effect profile compared with extracranial stimulation, though all forms of stimulation are safe. Methodological differences between the studies mean that direct comparisons are not straightforward. We have synthesised the findings of this review into a pragmatic decision tree, to guide the further management of the individual patient with pharmacoresistant focal-onset epilepsy.

Today, a growing need exists for greater research into cancer survivorship, focusing on different spheres of the day-to-day life of diagnosed patients. This article describes the design and implementation of VICAN (VIe après le CANcer), a national survey on French cancer survivors. The target population included patients aged 18-82, diagnosed with cancer between January and June 2010, and registered in one of the three main French Health Insurance Schemes. It was restricted to 12 tumour sites. Sampling was stratified using a non-proportional allocation, based on age at diagnosis (18-52 and 53-82) and tumour site. Data were collected from telephone interviews with patients 2 and 5 years after diagnosis, a medical survey completed by the physician who initiated cancer treatment, and information from the national medicoadministrative database on reimbursement data and hospital discharge records. First data collection, 2 years after diagnosis, occurred between March and December 2012. Second data collection, 5 years after diagnosis, will be conducted in 2015. Analyses will be conducted on various outcomes: quality of life, health status and psychosocial conditions, with a particular focus on the impact of cancer diagnosis on the labour market. The variety of measurements included in the survey will enable us to control a wide range of factors. The methodology of the VICAN survey was approved by three national ethics commissions. Results of the study will be disseminated through national and international research conferences, and in articles published in international peer-reviewed journals.

End of life care guidance for people with dementia is lacking and this has been made more problematic in England with the removal of one of the main end of life care guidelines which offered some structure, the Liverpool Care Pathway. This guidance gap may be eased with the development of heuristics (rules of thumb) which offer a fast and frugal form of decision-making. To develop a toolkit of heuristics (rules of thumb) for practitioners to use when caring for people with dementia at the end of life. A mixed-method study using a co-design approach to develop heuristics in three phases. In phase 1, we will conduct at least six focus groups with family carers, health and social care practitioners from both hospital and community care services, using the 'think-aloud' method to understand decision-making processes and to develop a set of heuristics. The focus group topic guide will be developed from the findings of a previous study of 46 interviews of family carers about quality end-of-life care for people with dementia and a review of the literature. A multidisciplinary development team of health and social care practitioners will synthesise the findings from the focus groups to devise and refine a toolkit of heuristics. Phase 2 will test the use of heuristics in practice in five sites: one general practice, one community nursing team, one hospital ward and two palliative care teams working in the community. Phase 3 will evaluate and further refine the toolkit of heuristics through group interviews, online questionnaires and semistructured interviews. This study has received ethical approval from a local NHS research ethics committee (Rec ref: 15/LO/0156). The findings of this study will be presented in peer-reviewed publications and national and international conferences. Published by the BMJ Publishing Group Limited.

Although there is evidence that socioeconomic conditions in adulthood are associated with worse self-rated health, the putative effect of early adverse life circumstances on adult self-rated health is not consistent. Besides, little is known on this subject in the context of middle-income countries. We aimed to investigate the association between indicators of socioeconomic position in early life and self-rated health in adulthood, taking into account the influence of current socioeconomic position. Cross-sectional. 3339 civil servants (44.5% male) working at a public university in Rio de Janeiro, Brazil, participants of the Pró-Saúde cohort study. Through a lifecourse approach, we evaluated if seven indicators of participants' socioeconomic position earlier in life were associated with worse self-rated health in adulthood. Ordinal logistic regression analysis with a proportional odds model was used. After adjusting for socioeconomic position in adulthood (education and income), the indicators of early socioeconomic position associated with poor self-rated health were as follows: not eating at home due to lack of money at the age of 12 (OR=1.29 95% CI 1.06 to 1.57) and having lived in a small city or rural area at the age of 12 (OR=1.51 95% CI 1.21 to 1.89). Self-rated health was associated with two indicators of remarkable experiences of poverty in early life, even when socioeconomic conditions improved throughout life. Our findings have shown a long-term impact of extreme socioeconomic hardship during childhood and/or adolescence on the development of social inequalities in health. In terms of implications for public health, our work emphasises that health policies, usually focused on adult lifestyle interventions, should be complemented by initiatives aimed at reducing socioeconomic inequalities during the earliest stages of development, such as childhood and adolescence.

Education and disability trends of older Americans, 2000-2014.
Tsai, Yuping
2017-09-01
Trends in disability among older Americans has declined since the 1980s. The study examines whether the trend continues to decline and whether educational disparities exist in the prevalence of functional limitations. I used the 2000-2014 National Health Interview Survey and included adults aged ≥65 years. Functional limitations was measured by three outcomes: the need for help with activities of daily living (ADLs) or instrumental activities of daily living (IADLs) and physical function limitations. I used a set of logistic models to estimate the average annual change rate of functional limitations. I examined whether the annual rate of change differed by education, age group and sex. During 2000-2014, the annual increase rate of ADL limitations was 1.7% (P < 0.001) and was 2.0% (P < 0.001) for physical function limitations; IADL limitation did not change significantly. All subgroups experienced an increase in ADL and physical function limitations except for adults with a more than high school education. The lower-educated group had a higher proportion and a higher annual rate of increase in all outcomes. Increasing trends in chronic conditions may contribute to the increasing trend in functional limitations. The study highlighted a large educational disparity in late-life disability among older Americans. Published by Oxford University Press on behalf of Faculty of Public Health 2016.

Occupations, including physical activity, are a strong determinant of health. However, mobility limitations can restrict opportunities to perform these occupations, which may affect quality of life. Some people will turn to adapted sports to meet their need to be involved in occupations. Little is known, however, about how participation in adapted sports affects the quality of life of people with mobility limitations. This study thus aimed to explore the influence of adapted sports on quality of life in adult wheelchair users. A mixed-method sequential explanatory design was used, including a quantitative and a qualitative component with a clinical research design. A total of 34 wheelchair users aged 18 to 62, who regularly played adapted sports, completed the Quality of Life Index (/30). Their scores were compared to those obtained by people of similar age without limitations (general population). Ten of the wheelchair users also participated in individual semi-structured interviews exploring their perceptions regarding how sports-related experiences affected their quality of life. The participants were 9 women and 25 men with paraplegia, the majority of whom worked and played an individual adapted sport (athletics, tennis or rugby) at the international or national level. People with mobility limitations who participated in adapted sports had a quality of life comparable to the group without limitations (21.9 ± 3.3 vs 22.3 ± 2.9 respectively), except for poorer family-related quality of life (21.0 ± 5.3 vs 24.1 ± 4.9 respectively). Based on the interviews, participants reported that the positive effect of adapted sports on the quality of life of people with mobility limitations operates mainly through the following: personal factors (behavior-related abilities and health), social participation (in general and through interpersonal relationships), and environmental factors (society's perceptions and support from the environment). Some contextual factors, such as resources and the accessibility of organizations and training facilities, are important and contributed indirectly to quality of life. Negative aspects, such as performance-related stress and injury, also have an effect. People with mobility limitations playing adapted sports and people without limitations have a similar quality of life. Participation in adapted sports was identified as having positive effects on self-esteem, self-efficacy, sense of belonging, participation in meaningful activities, society's attitude towards people with mobility limitations, and physical well-being. However, participants stated that this involvement, especially at higher levels, had a negative impact on their social life.
Vaccines against enteric infections for the developing world.
Czerkinsky, Cecil; Holmgren, Jan
2015-06-19
Since the first licensure of the Sabin oral polio vaccine more than 50 years ago, only eight enteric vaccines have been licensed for four disease indications, and all are given orally. While mucosal vaccines offer programmatically attractive tools for facilitating vaccine deployment, their development remains hampered by several factors: -limited knowledge regarding the properties of the gut immune system during early life; -lack of mucosal adjuvants, limiting mucosal vaccine development to live-attenuated or killed whole virus and bacterial vaccines; -lack of correlates/surrogates of mucosal immune protection; and -limited knowledge of the factors contributing to oral vaccine underperformance in children from developing countries. There are now reasons to believe that the development of safe and effective mucosal adjuvants and of programmatically sound intervention strategies could enhance the efficacy of current and next-generation enteric vaccines, especially in lesser developed countries which are often co-endemic for enteric infections and malnutrition. These vaccines must be safe and affordable for the world's poorest, confer long-term protection and herd immunity, and must be able to contain epidemics. © 2015 The Author(s) Published by the Royal Society.

Sexual Consent Capacity Assessment with Older Adults.
Syme, Maggie L; Steele, Debora
2016-09-01
Many healthcare providers have a limited knowledge of sexual and intimate expression in later life, often due to attitudinal and informational limitations. Further, the likelihood of an older adult experiencing cognitive decline increases in a long-term care (LTC) setting, complicating the ability of the providers to know if the older adult can make his or her own sexual decisions, or has sexual consent capacity. Thus, the team is left to question if and how to support intimacy and/or sexuality among residents with intimacy needs. Psychologists working with LTC need to be aware and knowledgeable about sexual consent capacity in older adulthood to be prepared to conduct evaluations and participate in planning care. Limited research is available to consult for best practices in sexual consent capacity assessment; however, models of assessment have been developed based on the best available evidence, clinical judgment, and practice. Existing models will be discussed and an integrated model will be illustrated via a case study. © The Author 2016. Published by Oxford University Press. All rights reserved.

Human milk oligosaccharides (HMOs) are complex sugars highly abundant in human milk but currently not present in infant formula. Rapidly accumulating evidence from in vitro and in vivo studies, combined with epidemiological associations and correlations, suggests that HMOs benefit infants through multiple mechanisms and in a variety of clinical contexts. Until recently, however, research on HMOs has been limited by an insufficient availability of HMOs. Most HMOs are found uniquely in human milk, and thus far it has been prohibitively tedious and expensive to isolate and synthesize them. This article reviews new strategies to overcome this lack of availability by generating HMOs through chemoenzymatic synthesis, microbial metabolic engineering, and isolation from human donor milk or dairy streams. Each approach has its advantages and comes with its own challenges, but combining the different methods and acknowledging their limitations creates new opportunities for research and application with the goal of improving maternal and infant health. © The Author(s) 2016.

A new bee species that excavates sandstone nests.
Orr, Michael C; Griswold, Terry; Pitts, James P; Parker, Frank D
2016-09-12
Humanity has long been fascinated by animals with apparently unfavorable lifestyles [1]. Nesting habits are especially important because they can limit where organisms live, thereby driving population, community, and even ecosystem dynamics [2]. The question arises, then, why bees nest in active termite mounds [3] or on the rim of degassing volcanoes, seemingly preferring such hardship [4]. Here, we present a new bee species that excavates sandstone nests, Anthophora (Anthophoroides) pueblo Orr (described in Supplemental Information, published with this article online), despite the challenges already inherent to desert life. Ultimately, the benefits of nesting in sandstone appear to outweigh the associated costs in this system. Copyright © 2016 Elsevier Ltd. All rights reserved.

In this report, we describe a male patient who presented with recurrent life-threatening hemoptysis due to the sequential formation of multiple pulmonary aneurysms. Both pulmonary artery coil embolization and right lower lobectomy were performed, with limited success. The patient experienced extensive bilateral femoral DVT extending into the inferior vena cava, with massive hemoptysis, fulfilling the diagnosis of Hughes-Stovin syndrome. A final diagnosis of Behçet disease was made following extensive investigation, and the patient responded well to prednisone 20 mg orally and azathioprine 100 mg orally.

Under-reporting of violent incidents against nursing staff.
Ferns, Terry
This article examines factors that contribute to nurses failing to report incidents of violence and aggression in the clinical area and it develops the information published in a previous article (Ferns and Chojnacka 2005). Broader social factors are considered, including gender, violence experienced by women, the status of the nursing profession and bureaucratic structures that contribute to under-reporting. The life experiences of individual nursing staff play a significant role in how they react to violence in the clinical area. Strategies to minimise violence against nurses should consider the social, political and personal issues that limit the reporting of violent incidents. Only by reporting such incidents can the extent of violence towards nurses be determined and minimised.

Fanconi anaemia (FA) is an inherited disease with congenital and developmental abnormalities, cross-linker hypersensitivity and extreme cancer predisposition. With better understanding of the genetic and molecular basis of the disease, and improved clinical management, FA has been transformed from a life-limiting paediatric disease to an uncommon chronic condition that needs lifelong multidisciplinary management, and a paradigm condition for the understanding of the gene-environment interaction in the aetiology of congenital anomalies, haematopoiesis and cancer development. Here we review genetic, molecular and clinical aspects of FA, and discuss current controversies and future prospects. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Mobile genetic elements (MGEs) such as viruses, plasmids, vesicles, gene transfer agents (GTAs), transposons and transpovirions, which collectively represent the mobilome, interact with cellular organisms from all three domains of life, including those thriving in the most extreme environments. While efforts have been made to better understand deep-sea vent microbial ecology, our knowledge of the mobilome associated with prokaryotes inhabiting deep-sea hydrothermal vents remains limited. Here we focus on the abyssal mobilome by reviewing accumulating data on viruses, plasmids and vesicles associated with thermophilic and hyperthermophilic Bacteria and Archaea present in deep-sea hydrothermal vents.

The objectives of this integrative review were to understand how parents of children with severe developmental disorders experience their involvement in end-of-life decision-making, how they prefer to be involved and what factors influence their decisions. We searched MEDLINE, EMBASE, CINAHL and PsycINFO. The search was limited to articles in English or Dutch published between January 2004 and August 2014. We included qualitative and quantitative original studies that directly investigated the experiences of parents of children aged 0-18 years with severe developmental disorders for whom an end-of-life decision had been considered or made. We identified nine studies that met all inclusion criteria. Reportedly, parental involvement in end-of-life decision-making varied widely, ranging from having no involvement to being the sole decision-maker. Most parents preferred to actively share in the decision-making process regardless of their child's specific diagnosis or comorbidity. The main factors that influenced parents in their decision-making were: their strong urge to advocate for their child's best interests and to make the best (possible) decision. In addition, parents felt influenced by their child's visible suffering, remaining quality of life and the will they perceived in their child to survive. Most parents of children with severe developmental disorders wish to actively share in the end-of-life decision-making process. An important emerging factor in this process is the parents' feeling that they have to stand up for their child's interests in conversations with the medical team. Copyright © 2015 Elsevier Ltd.

The scarcity of liquid water in the hyperarid core of the Atacama Desert makes this region one of the most challenging environments for life on Earth. The low numbers of microbial cells in the soils suggest that within the Atacama Desert lies the dry limit for life on our planet. Here, we show that the Ca-sulfate crusts of this hyperarid core are the habitats of lithobiontic micro-organisms. This microporous, translucent substrate is colonized by epilithic lichens, as well as endolithic free-living algae, fungal hyphae, cyanobacteria and non photosynthetic bacteria. We also report a novel type of endolithic community, "hypoendoliths", colonizing the undermost layer of the crusts. The colonization of gypsum crusts within the hyperarid core appears to be controlled by the moisture regime. Our data shows that the threshold for colonization is crossed within the dry core, with abundant colonization in gypsum crusts at one study site, while crusts at a drier site are virtually devoid of life. We show that the cumulative time in 1 year of relative humidity (RH) above 60% is the best parameter to explain the difference in colonization between both sites. This is supported by controlled humidity experiments, where we show that colonies of endolithic cyanobacteria in the Ca-sulfate crust undergo imbibition process at RH >60%. Assuming that life once arose on Mars, it is conceivable that Martian micro-organisms sought refuge in similar isolated evaporite microenvironments during their last struggle for life as their planet turned arid. © 2010 Blackwell Publishing Ltd.
Listening to Religious Music and Mental Health in Later Life.
Bradshaw, Matt; Ellison, Christopher G; Fang, Qijuan; Mueller, Collin
2015-12-01
Research has linked several aspects of religion--including service attendance, prayer, meditation, religious coping strategies, congregational support systems, and relations with God, among others--with positive mental health outcomes among older U.S. adults. This study examines a neglected dimension of religious life: listening to religious music. Two waves of nationally representative data on older U.S. adults were analyzed (n = 1,024). Findings suggest that the frequency of listening to religious music is associated with a decrease in death anxiety and increases in life satisfaction, self-esteem, and a sense of control across the 2 waves of data. In addition, the frequency of listening to gospel music (a specific type of religious music) is associated with a decrease in death anxiety and an increase in a sense of control. These associations are similar for blacks and whites, women and men, and low- and high-socioeconomic status individuals. Religion is an important socioemotional resource that has been linked with desirable mental health outcomes among older U.S. adults. This study shows that listening to religious music may promote psychological well-being in later life. Given that religious music is available to most individuals--even those with health problems or physical limitations that might preclude participation in more formal aspects of religious life--it might be a valuable resource for promoting mental health later in the life course. © The Author 2014.

This paper aimed to ascertain if hospital policy on medical futility helps in conflict resolution, and in ensuring good end-of-life care. Literature on the subject published in the last 5 years was identified through Pubmed, and those with empirical data pertaining to the outcomes of interest were examined. A systematic analysis was not possible as papers varied greatly in aims, designs, outcomes and their measures. Instead, the outcomes of representative papers were described and discussed. There is a widespread use of policies and guidelines based on the concept of medical futility. Conflicts are rare and appear to arise primarily from the manner in which policies are implemented. End-of-life care appears to be improving as evidenced by a significant number of deaths occurring following: (i) discussions involving patient, family, healthcare team members; (ii) cessation of intensive care and (iii) cessation of institution of palliative care. Deaths are increasingly taking place in the presence of family and outside the intensive care wards. Finally, post mortem audit of processes and practices indicate (i) compliance but in a limited manner with policies and recommended guidelines, (ii) family satisfaction and (iii) identify areas where improvement in end-of-life (EOL) care can be effected. Key areas are in improving education of, communication with, and documentation by all stakeholders. Hospital policies on medical futility have helped to resolve conflicts and improve end-of-life care. Prospective, multicentre and controlled trials will be useful in determining the value of specific interventions, obtaining generalisable data and facilitating implementation of better end-of-life care models.
Ammonia and urea handling by early life stages of fishes.
Zimmer, Alex M; Wright, Patricia A; Wood, Chris M
2017-11-01
Nitrogen metabolism in fishes has been a focus of comparative physiologists for nearly a century. In this Review, we focus specifically on early life stages of fishes, which have received considerable attention in more recent work. Nitrogen metabolism and excretion in early life differs fundamentally from that of juvenile and adult fishes because of (1) the presence of a chorion capsule in embryos that imposes a limitation on effective ammonia excretion, (2) an amino acid-based metabolism that generates a substantial ammonia load, and (3) the lack of a functional gill, which is the primary site of nitrogen excretion in juvenile and adult fishes. Recent findings have shed considerable light on the mechanisms by which these constraints are overcome in early life. Perhaps most importantly, the discovery of Rhesus (Rh) glycoproteins as ammonia transporters and their expression in ion-transporting cells on the skin of larval fishes has transformed our understanding of ammonia excretion by fishes in general. The emergence of larval zebrafish as a model species, together with genetic knockdown techniques, has similarly advanced our understanding of ammonia and urea metabolism and excretion by larval fishes. It has also now been demonstrated that ammonia excretion is one of the primary functions of the developing gill in rainbow trout larvae, leading to new hypotheses regarding the physiological demands driving gill development in larval fishes. Here, we highlight and discuss the dramatic changes in nitrogen handling that occur over early life development in fishes. © 2017. Published by The Company of Biologists Ltd.

Physical therapy encompasses the skilled treatment and care for patients across the life span through a multitude of different practice settings. This includes caring for individuals within end-of-life or palliative care settings. The goal of treatment in this stage of care is to relieve physical, social, psychological, and spiritual suffering in order to improve overall quality of life in patients with terminal illnesses. There has been limited research conducted to investigate the utilization of physical therapy interventions in palliative care settings. The purpose of this study was to contribute to the current research involving physical therapy and end-of-life care in terms of its efficacy, value, and how this value is perceived by patients and their caregivers. This was completed by independently screening and reviewing the studies that were published between the years 1994 and 2014 and related to this topic. The databases and journals searched included CINAHL, PUBMED, MEDLINE, Cochrane, PEDro, the Journal of Palliative Care, the American Journal of Hospice and Palliative Medicine, and Google Scholar. Thirteen qualitative articles were selected which met all inclusion criteria and discussed the role of physical therapy intervention in the palliative care setting. Methodological quality of articles were assessed using the QASP, scale and their findings were summarized and presented in table format. These articles support the utilization of physical therapy in palliative care settings and emphasizes the impact of physical therapy on improving patients' physical, social, and emotional well-being.

As the largest group of professional voice users, teachers are more likely to face voice disorders because of their specific job conditions. This study aimed to compare the quality of life in female teachers with and without voice complaints. This is a cross-sectional descriptive-analytical study. This was a cross-sectional study of samples of primary school female teachers with (n = 60) and without (n = 60) voice disorders. All teachers were serving in Tehran, Iran. Professional background information was obtained through interviews, and quality of life was measured using the 36-item Short Form Health Survey questionnaire. A comparison was made between the study groups to analyze the data. The mean age of teachers was 44 (standard deviation = 3.95) years. There were no significant differences between the two groups regarding their professional background. However, significant differences were observed between the two groups in all subscales of the 36-item Short Form Health Survey, including physical and social functioning, role limitations because of either physical or emotional problems, bodily pain, general health, vitality, and mental health (P < 0.05). Findings of this study point to the effect of voice complaint on quality of life and showed that teachers with voice complaints suffer from poor health-related quality of life. Therefore, both voice-specific and unspecific assessment methods are required for clinical diagnostics. Copyright © 2016. Published by Elsevier Inc.
Biosecurity policies at international life science journals.
van Aken, Jan; Hunger, Iris
2009-03-01
The prospect of bioterrorism has raised concerns about the potential abuse of scientific information for malign purposes and the pressure on scientific publishers to prevent the publication of "recipes" for weapons of mass destruction. Here we present the results of a survey of 28 major life science journals--20 English-language international journals and 3 Chinese and 5 Russian journals--with regard to their biosecurity policies and procedures. The survey addressed the extent to which life science journals have implemented biosecurity procedures in recent years, how authors and reviewers are advised about these procedures and the underlying concerns, and what the practical experiences have been. Few of the English-language publishers and none of the Russian and Chinese publishers surveyed implement formal biosecurity policies or inform their authors and reviewers about potentially sensitive issues in this area.
Life Prediction/Reliability Data of Glass-Ceramic Material Determined for Radome Applications

Brittle materials, ceramics, are candidate materials for a variety of structural applications for a wide range of temperatures. However, the process of slow crack growth, occurring in any loading configuration, limits the service life of structural components. Therefore, it is important to accurately determine the slow crack growth parameters required for component life prediction using an appropriate test methodology. This test methodology also should be useful in determining the influence of component processing and composition variables on the slow crack growth behavior of newly developed or existing materials, thereby allowing the component processing and composition to be tailored and optimized to specific needs. Through the American Society for Testing and Materials (ASTM), the authors recently developed two test methods to determine the life prediction parameters of ceramics. The two test standards, ASTM 1368 for room temperature and ASTM C 1465 for elevated temperatures, were published in the 2001 Annual Book of ASTM Standards, Vol. 15.01. Briefly, the test method employs constant stress-rate (or dynamic fatigue) testing to determine flexural strengths as a function of the applied stress rate. The merit of this test method lies in its simplicity: strengths are measured in a routine manner in flexure at four or more applied stress rates with an appropriate number of test specimens at each applied stress rate. The slow crack growth parameters necessary for life prediction are then determined from a simple relationship between the strength and the applied stress rate. Extensive life prediction testing was conducted at the NASA Glenn Research Center using the developed ASTM C 1368 test method to determine the life prediction parameters of a glass-ceramic material that the Navy will use for radome applications.

Value-based methods are increasingly used to reimburse therapeutic innovation, and the payment-by-results approach has been proposed for handling interventions with limited therapeutic evidence. Because most left ventricular assist devices are supported by preliminary efficacy data, we examined the effectiveness data of the HeartMate (Thoratec Corp, Pleasanton, CA) device to explore the application of the payment-by-results approach to these devices and to develop a model for handling reimbursements. According to our model, after establishing the societal economic countervalue for each month of life saved, each patient treated with one such device is associated to the payment of this countervalue for every month of survival lived beyond the final date of estimated life expectancy without left ventricular assist devices. Our base-case analysis, which used the published data of 68 patients who received the HeartMate device, was run with a monthly countervalue of euro 5000, no adjustment for quality of life, and a baseline life expectancy of 150 days without left ventricular assist devices. Sensitivity analysis was aimed at testing the effect of quality of life adjustments and changes in life expectancy without device. In our base-case analysis, the mean total reimbursement per patient was euro 82,426 (range, euro 0 to euro 250,000; N = 68) generated as the sum of monthly payments. This average value was close to the current price of the HeartMate device (euro 75,000). Sensitivity testing showed that the base-case reimbursement of euro 82,426 was little influenced by variations in life expectancy, whereas variations in utility had a more pronounced impact. Our report delineates an innovative procedure for appropriately allocating economic resources in this area of invasive cardiology.

Earlier life stressors can increase the risk of persistent anxiety and depressive symptoms in women after cancer, though our understanding of the underlying mechanisms is limited. In this study, we tested alternative life course models to determine which best described associations between exposure to stressors in childhood, adolescence, and adulthood, and self-reported health in women previously treated for breast, gynaecological, and blood cancer. Data were drawn from 351 Australian women within 2 years of completing active cancer treatment who were participating in the Women's Wellness After Cancer Program (WWACP) randomised controlled trial. A model-building framework compared "accumulative risk" and "sensitive period" stress exposure hypotheses with the saturated model to determine best fit. Symptoms of anxiety and depression were measured using the Center for Epidemiologic Studies Depression Scale (CES-D) and the Zung Self-rating Anxiety Scale (SAS). Participants with the greatest number of stressful life events (SLEs) reported higher anxiety scores and more depressive symptoms. Alternative life course models for psychological distress (measured through the CES-D and SAS) and stress were compared with the saturated model (i.e., the accumulative risk). The more restrictive "sensitive period" models were the best fit for depressive symptoms though none was significantly better than another. In contrast, an "early sensitive" model provided the best fit for anxiety data. Anxiety scores were higher in women with early life stressors. This study highlights the need for whole-of-life supportive care approaches for women previously treated for cancer, which should include targeted strategies for effective management of stress, anxiety and depression.

Building on social stress theory, this study has 2 aims. First, we aim to estimate the effects of stressful life events in childhood and adulthood on Successful Aging (SA). Second, we examine how unequal exposure to such life events between individuals with different socioeconomic position (SEP) contributes to socioeconomic inequalities in SA. We used 16-year longitudinal data from 2,185 respondents aged 55-85 years in 1992 in the Dutch nationally representative Longitudinal Aging Study Amsterdam. Measurement of SA was based on earlier work, in which we integrated trajectories in 9 indicators of functioning into an index of SA. Using path analysis, we investigated direct and indirect effects of parental and adulthood SEP as well as of self-reported childhood and adulthood life events on SA. Almost all included life events had negative direct effects on SA. Parental SEP had no direct effect on SA, whereas adulthood SEP had. Higher Parental SEP increased the likelihood of parental problems and parental death in childhood, resulting in negative indirect effects on SA. Higher adulthood SEP had both positive and negative indirect effects on SA, through increasing the likelihood of divorce and unemployment, but decreasing the likelihood of occupational disability. SEP and particular stressful life events are largely, but not entirely independent predictors of SA. We found that high and low SEP may increase exposure to particular events that negatively affect SA. Findings suggest that low (childhood) SEP and stressful life events are interrelated factors that may limit individual opportunities to age successfully. © The Author 2016.

Aging: Learning to Live a Finite Life.
Baars, Jan
2017-10-01
Although biodemographic research informs us that life expectancies have risen impressively during the last century, this has not led to much interest in these new horizons of aging. The instrumentalist culture of late modern societies, including its health cure system, has clearly difficulties to relate to the elusive but inevitable limitations of finite life. Moreover, as most people can be expected to survive into old age, thinking about finitude is easily postponed and reserved for those who are "really old." Indeed, a meaningful and realistic understanding of aging needs to include a confrontation with the finitude of life. Instead of reducing aging to the opposite or continuation of vital adulthood, it should be seen as something with a potentially broad and deep significance: a process of learning to live a finite life. As a contribution to this cultural repositioning of aging, the article presents a philosophical exploration of finitude and finite life. Among the discussed topics are the Stoic and Epicurean ways of living with death but also the necessity to expand the meaning of "finitude" beyond mortality. Aging is foremost a process of living through changes that are largely beyond our control although they require active responding. Next, individualistic or existentialist interpretations are criticized because finite lives presuppose a social world in which they emerge and on which they depend. Unfortunately, aging, the most important experiential source of knowledge about what it is to live a finite life, is neglected by the same culture that needs its wisdom. © The Author 2016.

Introduction Cardiovascular diseases are always one of the major causes of mortality in the world affecting all aspects of patients’ lives. Therefore, this study was conducted to summarize and provide a clear view of quality of life in these patients in Iran through a systematic review on the results of previously conducted studies. Methods In a systematic review, required information was collected by searching keywords of Iran, quality of life, heart failure, cardiac, heart, and their Persian equivalents in databases of Science Direct, Pubmed, IRAN doc, SID, Medlib and Magiran. The selected time period for searching articles was since 2000 to 2012. Inclusion criteria were: releasing of article during 2000 to 2012, articles reporting patients’ quality of life in any domains of heart diseases, and articles published in Persian and English. Extracted results first were summarized in Extraction Table, and then analyzed manually. Results Finally 18 of 1592 found articles were included in the study. A total of 3,797 cardiac patients' quality of life was measured using six different tools, the most important one of which was SF36 questionnaire. Among eight dimensions of SF36 questionnaire, the highest mean was for social role functioning with average score of 58.37 and the lowest for physical limitation (physical role functioning) with score of 42.95. Overall, mean of eight dimensions was 53.19. Among 4 general domains of quality of life, physical activity had the lowest average of 43.63 and average of general dimensions of quality of life was 47.65. The most important factors affecting quality of life were sex, age, education, marital status, occupational status, suffering duration, number of hospitalizations etc. Conclusion The results of the studies showed relatively low quality of life of cardiovascular patients in general. Therefore, according to the introduced effective factors in this study, it is necessary to consider regular programs for improving quality of life in these patients and providing suitable and qualitative services.

Nicholson, David
Wiley-Blackwell was formed in February 2007 as a result of the acquisition of Blackwell Publishing Ltd. by John Wiley & Sons, Inc. and the merger between Blackwell and Wiley's Scientific, Technical, and Medical business. Wiley-Blackwell publishes approximately 1,250 scholarly peer-reviewed journals including Monthly Notices of the Royal Astronomical Society and Astronomische Nachrichten, and has relationships with over 800 learned societies. The "secret life" of the article's title refers to the two broad areas of activity we undertake for our society partners, namely practical assistance and strategic advice. One of our goals at Wiley-Blackwell is to set the standard for both areas, and this article illustrates how we are doing this with a series of tangible examples.

Nurses' knowledge regarding advance directives may affect their administration and completion in end-of-life care. Confidence among nurses is a barrier to the provision of quality end-of-life care. This study investigated nurses' knowledge of advance directives and perceived confidence in end-of-life care, in Hong Kong, Ireland, Israel, Italy and the USA using a cross-sectional descriptive design (n = 1089). In all countries, older nurses and those who had more professional experience felt more confident managing patients' symptoms at end-of-life and more comfortable stopping preventive medications at end-of-life. Nurses in the USA reported that they have more knowledge and experience of advance directives compared with other countries. In addition, they reported the highest levels of confidence and comfort in dealing with end-of-life care. Although legislation for advance directives does not yet exist in Ireland, nurses reported high levels of confidence in end-of-life care. © 2016 The Authors International Journal of Nursing Practice Published by Wiley Publishing Asia Pty Ltd.

Data are sparse regarding the value of physical activity (PA) surveillance among older adults-particularly among those with mobility limitations. The objective of this study was to examine longitudinal associations between objectively measured daily PA and the incidence of cardiovascular events among older adults in the LIFE (Lifestyle Interventions and Independence for Elders) study. Cardiovascular events were adjudicated based on medical records review, and cardiovascular risk factors were controlled for in the analysis. Home-based activity data were collected by hip-worn accelerometers at baseline and at 6, 12, and 24 months postrandomization to either a physical activity or health education intervention. LIFE study participants (n=1590; age 78.9±5.2 [SD] years; 67.2% women) at baseline had an 11% lower incidence of experiencing a subsequent cardiovascular event per 500 steps taken per day based on activity data (hazard ratio, 0.89; 95% confidence interval, 0.84-0.96; P =0.001). At baseline, every 30 minutes spent performing activities ≥500 counts per minute (hazard ratio, 0.75; confidence interval, 0.65-0.89 [ P =0.001]) were also associated with a lower incidence of cardiovascular events. Throughout follow-up (6, 12, and 24 months), both the number of steps per day (per 500 steps; hazard ratio, 0.90, confidence interval, 0.85-0.96 [ P =0.001]) and duration of activity ≥500 counts per minute (per 30 minutes; hazard ratio, 0.76; confidence interval, 0.63-0.90 [ P =0.002]) were significantly associated with lower cardiovascular event rates. Objective measurements of physical activity via accelerometry were associated with cardiovascular events among older adults with limited mobility (summary score >10 on the Short Physical Performance Battery) both using baseline and longitudinal data.

Factors influencing deprescribing habits among geriatricians.
Ní Chróinín, Danielle; Ní Chróinín, Chantelle; Beveridge, Alexander
2015-07-01
deprescribing habits among physicians managing older, frailer, cognitively impaired patients have not been well investigated. an anonymised electronic survey was disseminated to all members of an international geriatric society/local advanced trainee network (N = 930). This comprised a Likert-scale analysis of factors influencing desprescribing, and five case vignettes, detailing a patient with progressive cognitive impairment and dependency, on a background of ischaemic heart disease and hypertension. among 134 respondents (response rate 14.4%), 47.4% were female, 48.9% aged 36-50 years and 84.1% specialists (15.9% trainees). Respondents commonly rated limited life expectancy (96.2%) and cognitive impairment (84.1%) as very/extremely important to deprescribing practices. On multivariable analysis, older respondents less commonly rated functional dependency (odds ratio [OR] 0.22 per change in age category; P < 0.001) and limited life expectancy (OR 0.09, P = 0.04) important when deprescribing, while female participants (OR 3.03, P < 0.001) and trainees (versus specialists OR 14.29, P < 0.001) more often rated adherence to evidence-based guidelines important. As vignettes described increasing dependency and cognitive impairment, physicians were more likely to stop donepezil, aspirin, atorvastatin and antihypertensives (all P < 0.001 for trend). Aspirin (93.6%) and ramipril (94.1%) were most commonly deprescribed. Commonest reasons cited for deprescribing medications were 'dementia severity', followed by pill burden. in this exploratory analysis, geriatricians rated limited life expectancy and cognitive impairment very important in driving deprescribing practices. Geriatricians more often deprescribed multiple medications in the setting of advancing dependency and cognitive impairment, driven by dementia severity and pill burden concerns. Physician characteristics also influence deprescribing practices. Further exploration of factors influencing deprescribing patterns, and patient outcomes, is needed. © The Author 2015.

Cancelled and missed colonoscopy appointments waste resources, increase colonoscopy delays, and can adversely affect patient outcomes. We examined individual and organizational factors associated with missed and cancelled colonoscopy appointments in Veteran Health Administration facilities. From 69 facilities meeting inclusion criteria, we identified 27,994 patients with colonoscopy appointments scheduled for follow-up, on the basis of positive fecal occult blood test results, between August 16, 2009 and September 30, 2011. We identified factors associated with colonoscopy appointment status (completed, cancelled, or missed) by using hierarchical multinomial regression. Individual factors examined included age, race, sex, marital status, residence, drive time to nearest specialty care facility, limited life expectancy, comorbidities, colonoscopy in the past decade, referring facility type, referral month, and appointment lead time. Organizational factors included facility region, complexity, appointment reminders, scheduling, and prep education practices. Missed appointments were associated with limited life expectancy (odds ratio [OR], 2.74; P = .0004), no personal history of polyps (OR, 2.74; P < .0001), high facility complexity (OR, 2.69; P = .007), dual diagnosis of psychiatric disorders and substance abuse (OR, 1.82; P < .0001), and opt-out scheduling (OR, 1.57; P = .02). Cancelled appointments were associated with age (OR, 1.61; P = .0005 for 85 years or older and OR, 1.44; P < .0001 for 65-84 years old), no history of polyps (OR, 1.51; P < .0001), and opt-out scheduling (OR, 1.26; P = .04). Additional predictors of both outcomes included race, marital status, and lead time. Several factors within Veterans Health Administration clinic control can be targeted to reduce missed and cancelled colonoscopy appointments. Specifically, developing systems to minimize referrals for patients with limited life expectancy could reduce missed appointments, and use of opt-in scheduling and reductions in appointment lead time could improve both outcomes.

Improvements in care and treatment have led to more young adults with life-limiting conditions living beyond childhood, which means they must make the transition from children's to adult services. This has proved a challenging process for both young adults and service providers, with complex transition interventions interacting in unpredictable ways with local contexts. To explain how intervention processes interact with contextual factors to help transition from children's to adult services for young adults with life-limiting conditions. Systematic realist review of the literature. Literature was sourced from four electronic databases: Embase, MEDLINE, Science Direct and Cochrane Library from January 1995 to April 2016. This was supplemented with a search in Google Scholar and articles sourced from reference lists of included papers. Data were extracted using an adapted standardised data extraction tool which included identifying information related to interventions, mechanisms, contextual influences and outcomes. Two reviewers assessed the relevance of papers based on the inclusion criteria. Methodological rigor was assessed using the relevant Critical Appraisal Skills Programme tools. 78 articles were included in the review. Six interventions were identified related to an effective transition to adult services. Contextual factors include the need for children's service providers to collaborate with adult service providers to prepare an environment with knowledgeable staff and adequate resources. Mechanisms triggered by the interventions include a sense of empowerment and agency amongst all stakeholders. Early planning, collaboration between children's and adult service providers, and a focus on increasing the young adults' confidence in decision-making and engaging with adult services, are vital to a successful transition. Interventions should be tailored to their context and focused not only on organisational procedures but on equipping young adults, parents/carers and staff to engage with each other effectively.

To summarise and synthesise published qualitative studies to characterise factors that shape patient and caregiver experiences of chronic heart failure (CHF), chronic obstructive pulmonary disease (COPD) and chronic kidney disease (CKD). Meta-review of qualitative systematic reviews and metasyntheses. Papers analysed using content analysis. CINAHL, EMBASE, MEDLINE, PsychINFO, Scopus and Web of Science were searched from January 2000 to April 2015. Systematic reviews and qualitative metasyntheses where the participants were patients, caregivers and which described experiences of care for CHF, COPD and CKD in primary and secondary care who were aged ≥18 years. Searches identified 5420 articles, 53 of which met inclusion criteria. Reviews showed that patients' and caregivers' help seeking and decision-making were shaped by their degree of structural advantage (socioeconomic status, spatial location, health service quality); their degree of interactional advantage (cognitive advantage, affective state and interaction quality) and their degree of structural resilience (adaptation to adversity, competence in managing care and caregiver response to demands). To the best of our knowledge, this is the first synthesis of qualitative systematic reviews in the field. An important outcome of this overview is an emphasis on what patients and caregivers value and on attributes of healthcare systems, relationships and practices that affect the distressing effects and consequences of pathophysiological deterioration in CHF, COPD and CKD. Interventions that seek to empower individual patients may have limited effectiveness for those who are most affected by the combined weight of structural, relational and practical disadvantage identified in this overview. We identify potential targets for interventions that could address these disadvantages. PROSPERO CRD42014014547. Published by the BMJ Publishing Group Limited.

The thermal limits to life on Earth
NASA Astrophysics Data System (ADS)
Clarke, Andrew
2014-04-01
Living organisms on Earth are characterized by three necessary features: a set of internal instructions encoded in DNA (software), a suite of proteins and associated macromolecules providing a boundary and internal structure (hardware), and a flux of energy. In addition, they replicate themselves through reproduction, a process that renders evolutionary change inevitable in a resource-limited world. Temperature has a profound effect on all of these features, and yet life is sufficiently adaptable to be found almost everywhere water is liquid. The thermal limits to survival are well documented for many types of organisms, but the thermal limits to completion of the life cycle are much more difficult to establish, especially for organisms that inhabit thermally variable environments. Current data suggest that the thermal limits to completion of the life cycle differ between the three major domains of life, bacteria, archaea and eukaryotes. At the very highest temperatures only archaea are found with the current high-temperature limit for growth being 122 °C. Bacteria can grow up to 100 °C, but no eukaryote appears to be able to complete its life cycle above ~60 °C and most not above 40 °C. The lower thermal limit for growth in bacteria, archaea, unicellular eukaryotes where ice is present appears to be set by vitrification of the cell interior, and lies at ~-20 °C. Lichens appear to be able to grow down to ~-10 °C. Higher plants and invertebrates living at high latitudes can survive down to ~-70 °C, but the lower limit for completion of the life cycle in multicellular organisms appears to be ~-2 °C.

Objectives To evaluate the impact of total knee replacement on quality of life in people with knee osteoarthritis and to estimate associated differences in lifetime costs and quality adjusted life years (QALYs) according to use by level of symptoms. Design Marginal structural modeling and cost effectiveness analysis based on lifetime predictions for total knee replacement and death from population based cohort data. Setting Data from two studies-Osteoarthritis Initiative (OAI) and the Multicenter Osteoarthritis Study (MOST)-within the US health system. Participants 4498 participants with or at high risk for knee osteoarthritis aged 45-79 from the OAI with no previous knee replacement (confirmed by baseline radiography) followed up for nine years. Validation cohort comprised 2907 patients from MOST with two year follow-up. Intervention Scenarios ranging from current practice, defined as total knee replacement practice as performed in the OAI (with procedural rates estimated by a prediction model), to practice limited to patients with severe symptoms to no surgery. Main outcome measures Generic (SF-12) and osteoarthritis specific quality of life measured over 96 months, model based QALYs, costs, and incremental cost effectiveness ratios over a lifetime horizon. Results In the OAI, total knee replacement showed improvements in quality of life with small absolute changes when averaged across levels of confounding variables: 1.70 (95% uncertainty interval 0.26 to 3.57) for SF-12 physical component summary (PCS); -10.69 (-13.39 to -8.01) for Western Ontario and McMaster Universities arthritis index (WOMAC); and 9.16 (6.35 to 12.49) for knee injury and osteoarthritis outcome score (KOOS) quality of life subscale. These improvements became larger with decreasing functional status at baseline. Provision of total knee replacement to patients with SF-12 PCS scores <35 was the optimal scenario given a cost effectiveness threshold of $200 000/QALY, with cost savings of $6974 ($5789 to $8269) and a minimal loss of 0.008 (-0.056 to 0.043) QALYs compared with current practice. These findings were reproduced among patients with knee osteoarthritis from the MOST cohort and were robust against various scenarios including increased rates of total knee replacement and mortality and inclusion of non-healthcare costs but were sensitive to increased deterioration in quality of life without surgery. In a threshold analysis, total knee replacement would become cost effective in patients with SF-12 PCS scores ≤40 if the associated hospital admission costs fell below $14 000 given a cost effectiveness threshold of $200 000/QALY. Conclusion Current practice of total knee replacement as performed in a recent US cohort of patients with knee osteoarthritis had minimal effects on quality of life and QALYs at the group level. If the procedure were restricted to more severely affected patients, its effectiveness would rise, with practice becoming economically more attractive than its current use.

Evaluation of Hose in Hose Transfer Line Service Life for Hanfords Interim Stabilization Program
DOE Office of Scientific and Technical Information (OSTI.GOV)
TORRES, T.D.
RPP-6153, Engineering Task Plan for Hose-in-Hose Transfer System for the Interim Stabilization Program (Torres, 2000a), defines the programmatic goals, functional requirements, and technical criteria for the development and subsequent installation of waste transfer line equipment to support Hanford's Interim Stabilization Program. RPP-6028, Specification for Hose in Hose Transfer Lines for Hanford's Interim Stabilization Program (Torres, 2000b), has been issued to define the specific requirements for the design, manufacture, and verification of transfer line assemblies for specific waste transfer applications associated with Interim Stabilization. Included in RPP-6028 are tables defining the chemical constituents of concern to which transfer lines will bemore » exposed. Current Interim Stabilization Program planning forecasts that the at-grade transfer lines will be required to convey pumpable waste for as much as three years after commissioning, RPP-6028 Section 3.2.7. Performance Incentive Number ORP-05 requires that all the Single Shell Tanks be Interim Stabilized by September 30, 2003. The Tri-Party Agreement (TPA) milestone M-41-00, enforced by a federal consent decree, requires all the Single Shell Tanks to be Interim stabilized by September 30, 2004. By meeting the Performance Incentive the TPA milestone is met. Prudent engineering dictates that the equipment used to transfer waste have a life in excess of the forecasted operational time period, with some margin to allow for future adjustments to the planned schedule. This document evaluates the effective service life of the Hose-in-Hose Transfer Lines, based on information submitted by the manufacturer, published literature and calculations. The effective service life of transfer line assemblies is a function of several factors. Foremost among these are the hose material's resistance to the harmful effects of process fluid characteristics, ambient environmental conditions, exposure to ionizing radiation and the manufacturer's stated shelf life. In order to determine the transfer line service life this evaluation examines the certification of shelf life, the certification of chemical compatibility with waste, catalog information of ambient ratings and published literature on the effects of exposure to ionizing radiation on the mechanical properties of elastomeric materials. During initial hose procurements, the hose-in-hose transfer line vendor River Bend Hose Specialty (RBHS) submitted a letter, dated 6/8/00, which recommended the service and shelf life of the hose to be seven years. In submittals for later hose procurements, RBHS submitted a letter, dated 11/6/00, which recommended the service life of the hose to be three years. This submittal was followed by documentation, on 2/14/01, which submitted new storage requirements and restated the seven year shelf life. RBHS revised their original hose service life estimate to a more conservative three years due to concerns over the effects of chemicals in transferred waste. The above mentioned submittals from RBHS are the primary drivers of the three year service life limit established by this document.« less

Primary biliary cirrhosis (PBC) is an autoimmune liver disease with approximately 50% of patients experiencing fatigue. This can be a particularly debilitating symptom, affecting quality of life and resulting in social isolation. Fatigue is highlighted by patients as a priority for research and patient support groups were involved in designing this trial. This is the first randomised controlled trial to investigate a treatment for fatigue in PBC. The trial protocol is innovative as it utilises novel magnetic resonance spectroscopy (MRS) techniques as an outcome measure. The protocol will be valuable to research groups planning clinical trials targeting fatigue in PBC and also transferrable to other conditions associated with fatigue. RITPBC is a Medical Research Council (MRC) and National Institute for Health Research (NIHR) Efficacy and Mechanism Evaluation Programme (EME)-funded project. It is a phase II, single-centre, randomised controlled, double-blinded trial comparing rituximab with placebo in fatigued PBC patients. 78 patients with PBC and moderate to severe fatigue will be randomised to receive two infusions of rituximab or placebo. The study aims to assess whether rituximab improves fatigue in patients with PBC, the safety, and tolerability of rituximab in PBC and the sustainability of any beneficial actions. The primary outcome will be an improvement in fatigue domain score of the PBC-40, a disease-specific quality of life measure, evaluated at 12-week assessment. Secondary outcome measures include novel MRS techniques assessing muscle bioenergetic function, physical activity, anaerobic threshold and symptom, and quality of life measures. The trial started recruiting in October 2012 and recruitment is ongoing. The trial has ethical approval from the NRES Committee North East, has Clinical Trial Authorisation from MHRA and local R&D approval. Trial results will be communicated to participants, presented at national and international meetings and published in peer-reviewed journals. ISRCTN03978701.

The European Space Agency has recently initiated a study of the human responses, limits and needs with regard to the stress environments of interplanetary and planetary missions. Emphasis has been laid on human health and performance care as well as advanced life support developments including bioregenerative life support systems and environmental monitoring. The overall study goals were as follows: (i) to define reference scenarios for a European participation in human exploration and to estimate their influence on the life sciences and life support requirements; (ii) for selected mission scenarios, to critically assess the limiting factors for human health, wellbeing, and performance and to recommend relevant countermeasures; (iii) for selected mission scenarios, to critically assess the potential of advanced life support developments and to propose a European strategy including terrestrial applications; (iv) to critically assess the feasibility of existing facilities and technologies on ground and in space as testbeds in preparation for human exploratory missions and to develop a test plan for ground and space campaigns; (v) to develop a roadmap for a future European strategy towards human exploratory missions, including preparatory activities and terrestrial applications and benefits. This paper covers the part of the HUMEX study dealing with lunar missions. A lunar base at the south pole where long-time sunlight and potential water ice deposits could be assumed was selected as the Moon reference scenario. The impact on human health, performance and well being has been investigated from the view point of the effects of microgravity (during space travel), reduced gravity (on the Moon) and abrupt gravity changes (during launch and landing), of the effects of cosmic radiation including solar particle events, of psychological issues as well as general health care. Countermeasures as well as necessary research using ground-based test beds and/or the International Space Station have been defined. Likewise advanced life support systems with a high degree of autonomy and regenerative capacity and synergy effects were considered where bioregenerative life support systems and biodiagnostic systems become essential. Finally, a European strategy leading to a potential European participation in future human exploratory missions has been recommended. c2003 COSPAR. Published by Elsevier Ltd. All rights reserved.

While universal screening for CD in patients with diabetes is frequently advocated, objective data is limited as to benefits on diabetes control, bone health or quality of life related to the adoption of a gluten-free diet (GFD) in the large proportion of patients with diabetes with asymptomatic CD. The Celiac Disease and Diabetes-Dietary Intervention and Evaluation Trial (CD-DIET) study is a multicenter, randomised controlled trial to evaluate the efficacy and safety of a GFD in patients with type 1 diabetes with asymptomatic CD. Children and adults (8-45 years) with type 1 diabetes will be screened for asymptomatic CD. Eligible patients with biopsy-proven CD will be randomly assigned in a 1:1 ratio to treatment with a GFD for 1 year, or continue with a gluten-containing diet. The primary outcome will evaluate the impact of the GFD on change in glycated haemoglobin. Secondary outcomes will evaluate changes in bone mineral density, blood glucose variability and health-related quality of life between GFD-treated and the regular diet group over a 1-year period. The study was initiated in 2012 and has subsequently expanded to multiple paediatric and adult centres in Ontario, Canada. The findings from this study will provide high-quality evidence as to the impact of GFD treatment on glycaemic control and complications in asymptomatic children and adults with CD and type 1 diabetes.

The evidence on the effect of secondhand smoke (SHS) on Health Related Quality of Life (HRQoL) is limited. We examined the relation between SHS and HRQoL among Chinese in Hong Kong. Adult never smokers from a probability sample of three cross-sectional waves (2010, 2012, 2013) of The Hong Kong Family and Health Information Trends Survey who completed the Cantonese-version of Short-Form 12 Health Survey Questionnaire (SF12v2) were included in the data analysis conducted in 2014. Models were used to examine associations of SHS with SF12 domains and summary scores of Physical (PCS12) and Mental Component (MCS12) with subgroups analysis by SHS locations. After adjustments, SHS was associated with lower scores on all SF12 domains except physical functioning. PCS12 (regress coefficient=-0.76, 95% CI -1.34 to -0.17) and MCS12 (regress coefficient=-1.35, 95% CI -2.06 to -0.64) were lower in those with SHS exposure than those non-exposed. Those exposed to SHS in outdoor public places had lower scores on most SF12 domains and PSC12 and MCS12. SHS exposure in one's home and workplace was associated with lower scores on role physical, body pain and role emotional while SHS exposure in friends' homes was additionally associated with lower social functioning and mental health scores. Lower MCS12 was associated with SHS exposure at all locations except one's home. Our study showed that SHS exposure, particularly in outdoor public places, was associated with decreased HRQoL. It can provide new evidence for stronger smoke-free policies on public places and promoting smoke-free homes. Published by the BMJ Publishing Group Limited.

Neurodegenerative diseases, such as dementia, have a profound impact on those with the conditions and their family carers. Consequently, the accurate measurement of family carers' quality of life (QOL) is important. Generic measures may miss key elements of the impact of these conditions, so using disease-specific instruments has been advocated. This systematic review aimed to identify and examine the psychometric properties of disease-specific outcome measures of QOL of family carers of people with neurodegenerative diseases (Alzheimer's disease and other dementias; Huntington's disease; Parkinson's disease; multiple sclerosis; and motor neuron disease). Systematic review. Instruments were identified using 5 electronic databases (PubMed, PsycINFO, Web of Science, Scopus and the International Bibliography of the Social Sciences (IBSS)) and lateral search techniques. Only studies which reported the development and/or validation of a disease-specific measure for adult family carers, and which were written in English, were eligible for inclusion. The methodological quality of the included studies was evaluated using the COnsensus based Standards for the selection of health Measurement Instruments (COSMIN) checklist. The psychometric properties of each instrument were examined. 676 articles were identified. Following screening and lateral searches, a total of 8 articles were included; these reported 7 disease-specific carer QOL measures. Limited evidence was available for the psychometric properties of the 7 instruments. Psychometric analyses were mainly focused on internal consistency, reliability and construct validity. None of the measures assessed either criterion validity or responsiveness to change. There are very few measures of carer QOL that are specific to particular neurodegenerative diseases. The findings of this review emphasise the importance of developing and validating psychometrically robust disease-specific measures of carer QOL. Published by the BMJ Publishing Group Limited.

To identify predictive markers for the outcomes of anti-vascular endothelial growth factor therapy for neovascular age-related macular degeneration (nAMD). AURA was a retrospective, observational, multicentre study that monitored the 2-year outcomes following intravitreal ranibizumab treatment in patients with nAMD. Using stepwise regression analysis, we evaluated the association between visual acuity outcomes, baseline characteristics and resource utilisation in order to determine which variables are significantly linked to outcomes in AURA. We also examined the relationship between visual acuity outcomes and number of injections received. Analyses were performed using data from year 1 (n=1695) and year 2 completers (n=1184). Logistic analysis showed that baseline visual acuity score, age at start of therapy, number of ophthalmoscopies and optical coherence tomography (OCT) (combined) and number of injections (ranibizumab) were significant (p<0.05) prognostic factors for vision maintenance (loss <15 letters) or vision gain (≥15 letters). Patients who received >7 injections (in 1 year) or >14 injections (over 2 years) gained more letters and demonstrated greater vision maintenance (loss of <15 letters) than patients who received fewer injections. There was a significant (p<0.05) association between number of injections and national reimbursement schemes and OCT. A number of factors that are predictive of treatment outcomes in a real-life setting were identified. Notably, the decline of treatment benefits may be linked to number of injections and a failure to visit clinicians and receive OCT as required. These findings may be helpful in guiding ophthalmologist treatment decisions under limited time and financial constraints. NCT01447043. Published by the BMJ Publishing Group Limited.

'Keeping your body and mind active': an ethnographic study of aspirations for healthy ageing.
Guell, Cornelia; Shefer, Guy; Griffin, Simon; Ogilvie, David
2016-01-07
To describe and explore perceptions, practices and motivations for active living in later life. Qualitative study with semistructured interviews and 'semistructured' participant observations of participant-selected activities, such as exercise classes, private or organised walks, shopping and gardening. 27 participants (65-80 years) from the European Prospective Investigation into Cancer Norfolk study, purposefully selected by gender, age, occupational class, living status and residential location; 19 of the participants agreed to be accompanied for observed activities. Participants' homes, neighbourhoods, places of leisure activities and workplaces in Norfolk, England. All participants regarded a positive attitude as important for healthy ageing; this included staying active, both physically and mentally through sedentary activities such as reading and crosswords. 'Getting out of the house', being busy, or following a variety of interests were regarded as both important motivators and descriptions of their 'activeness'. Purposeful activities formed an important part of this, for example, still being engaged in paid or voluntary work, having caring responsibilities, or smaller incidental activities such as helping neighbours or walking for transport. Many also reported adapting previous, often lifelong, activity preferences and habits to their ageing body, or replacing them altogether with lower impact activities such as walking. This included adapting to the physical limitations of partners and friends which dictated the intensity and frequency of shared activities. The social context of activities could thus form a barrier to active living, but could also encourage it through companionship, social responsibilities and social pressures. Promoting and maintaining physical activity among older people may require more attention to activeness as an attitude and way of life as well as to its social context, and initiatives encouraging broader activity habits rather than discrete activities.

Dual use research: investigation across multiple science disciplines.
Oltmann, Shannon
2015-04-01
Most recent studies of dual use research have focused on the life sciences, although some researchers have suggested that dual use research occurs across many disciplines. This research is an initial investigation into the prevalence of dual use research in other scientific disciplines by surveying senior editors of scientific journals, drawn from Journal Citation Reports. The survey was emailed to 7,500 journal editors with a response rate of 10.1 %. Approximately 4.8 % of life science editors reported they had to consider whether to publish dual use research and 38.9 % said they decided to not publish the research in question. In disciplines other than the life sciences, 7.2 % of editors from other science disciplines reported that they had to consider whether to publish dual use research, and 48.4 % declined to publish it. The survey investigated relationships between dual use and the journal's source of funding and place of publication, but no relationships were found. Further research is needed to better understand the occurrence of dual use research in other science disciplines.
Utilisation of the c-fos immunohistochemical method: a 2004 quantitative study.
Robert, C; Arreto, C D; Gaudy, J F; Wilson, C S
2007-10-01
The aim of this study was to provide a quantitative view of the utilisation of the c-fos immunohistochemical method. Articles including the term "c-fos" in their title, abstract or keywords and published in 2004 were retrieved from the Current Content/Life Sciences or Current Content/Clinical Medicine collection of the SCI database. The 933 article-type documents retained were distributed in almost all the sub-disciplines of the Life Sciences and Clinical Medicine, but were principally published in the field of neuroscience. They were authored by researchers from 44 countries - the most prolific were the USA (435 articles), Japan (135) and the UK (55). The 933 articles were published in 283 different journals; all but one of the top-20 most prolific journals are in the Life Sciences discipline, and their Impact Factors ranged from 2.0 to 7.9. A comparison of the USA and the European Union scientific profiles is also made.
Documenting the Durability and Service Life of Pressure-treated Wood
Stan Lebow; Bessie Woodward; Patricia Lebow
2014-01-01
Estimates of service life are increasingly used to compare life cycle costs of building materials. Because of a lack of published data for treated wood, some users assume a relatively low service life for wood in comparison to alternative materials. Such bias against durable wood products may cause alternative materials to appear more economical. This paper discusses...

We aimed to study the psychosocial adjustment (PSA), psychiatric morbidity and quality of life of adolescents and young adults with congenital heart disease (CHD) to determine which demographic and clinical variables negatively affect adjustment and which increase resilience. The study included 74 patients with CHD, 41 male and 33 female, aged between 12 and 26 years (mean 18.76±3.86). Demographic information and a complete clinical history were obtained. The participants were interviewed regarding social support, family environment, self-image and physical limitations. A standardized psychiatric interview was conducted, and self-report questionnaires were administered for assessment of PSA (Youth Self Report and Adult Self Report) and quality of life (World Health Organization Quality of Life - Short Version). A caregiver completed an observational version of the PSA questionnaire (Child Behavior Checklist or Adult Behavior Checklist). Female participants showed more feelings of anxiety and depression (U=952.500; p=0.003), thought problems (U=929.500; p=0.005) and aggressive behavior (U=999.000; p=0.000). They also showed a higher rate of psychopathology. Patients with complex forms of CHD reported more thought problems (U=442.000; p=0.027) and internalization (U=429.000; p=0.021). Compared to the Portuguese population as a whole, participants showed better quality of life in the domains of social relationships (t=2.333; p=0.022) and environment (t=3.754; p=0.000). Patients who had undergone surgery had worse quality of life in physical terms (t=-1.989; p=0.050), social relationships (t=-2.012; p=0.048) and general quality of life (U=563.000; p=0.037), compared to those who were not operated. Better social support was associated with better quality of life in physical terms (t=3.287; p=0.002) and social relationships (t=3.669; p=0.000). Better school performance was also associated with better overall quality of life (U=457.000; p=0.046), less withdrawn behavior (U=812.500; p=0.031), fewer feelings of anxiety and depression (U=854.000; p=0.009), fewer attention problems (U=903.500; p=0.001), and lower scores for internalization (U=817.000; p=0.029) and externalization (U=803.500; p=0.042). Physical limitations had a detrimental effect on quality of life (U=947.500; p=0.001). Female participants were more prone to worse psychological adjustment and to psychopathology. Patients with complex forms of CHD showed worse PSA, as they need regular care, which restricts social contact with peers and family and integration in school and leisure activities. Patients who had undergone surgery showed worse quality of life as they often have long hospital stays, during which social activities are restricted, making it more difficult for them to develop a good social support network. They require close medical care, and the restrictions on their activities may be life-limiting. Their sense of survival may also be threatened. Patients with CHD appear to be more prone to psychopathology and female patients are more likely to show worse PSA. Social support was shown to play a crucial role in buffering stress and promoting patients' adjustment. Copyright © 2013 Sociedade Portuguesa de Cardiologia. Published by Elsevier España.

Advance care planning has been shown to improve end-of-life care but it was developed in the USA and most research has been conducted in western communities. We aimed to study the attitudes and perceptions of patients with life-limiting illnesses, informal caregivers, doctors, nurses and medical social workers regarding advance care planning in a multi-cultural family-centric community. We conducted an explorative qualitative study, using focus groups and individual in-depth interviews. We used purposive sampling techniques to recruit 61 adults (15 doctors, 13 nurses, 5 medical social workers, 15 patients and 13 caregivers) from multiple healthcare settings across the country. The participants are genuinely anxious about the implementation of advance care planning. They had positive and negative expectations of advance care planning. Many were confused about the legal framework for healthcare decision-making and expected advance care planning to be of limited value because family members, rather than the patient, were usually the key decision-makers. A nuanced approach to advance care planning which considers the family network is required in multi-cultural family centric communities. Policies should be reconciled to create a more consistent message that respects patients, the family, and is legally coherent. Further research could focus on adaptations of advance care planning to promote its acceptance in such communities. Copyright © 2018. Published by Elsevier Inc.
[Sub-maximal aerobic capacity and quality of life of patients with rheumatoid arthritis].
Lataoui, S; Belghali, S; Zeglaoui, H; Bouajina, E; Ben Saad, H
2017-01-01
Studies about sub-maximal aerobic capacity of patients with rheumatoid arthritis are scarce. To assess the sub-maximal aerobic capacity of these patients through the 6-min walk test, estimated age of the "muscular and cardiorespiratory" chain. Thirty-seven consecutive patients (aged 20 to 60 years) with newly diagnosed rheumatoid arthritis will be included. Non-inclusion criteria will be: use of drugs (e.g.; methotrexate, beta-blockers), orthopaedic or rheumatologic conditions (other than rheumatoid arthritis) that may alter walking ability and recent infections. Exclusion criteria will be: 6-min walking test contra-indications and imperfect performance of the required lung function and walking maneuvers. Signs of walking intolerance will be: test interruption, distance ≤lower limit of normal, dyspnea score ≥5/10 (visual analogue scale) at the end of the test, haemoglobin oxygen saturation (SpO 2 ) drop ≥5%, cardiac frequency at the end of the test ≤60% of maximum predicted. An estimated "muscular and cardiorespiratory chain" age higher than the chronological one will be considered as a sign of accelerated ageing. A high percentage of patients suffering from rheumatoid arthritis would show evidences of walking limitation and accelerated "muscular and cardiorespiratory chain" ageing. There would be a significant correlation between the walking test and clinical, biological, radiological and pulmonary function data and the patients' quality-of-life status. Copyright © 2016 SPLF.

Formaldehyde and formic acid are reactive impurities found in commonly used excipients and can be responsible for limiting drug product shelf-life. Described here is the use of activated carbon in drug product packaging to attenuate formaldehyde-induced and formic acid-induced drug degradation in tablets and cross-linking in hard gelatin capsules. Several pharmaceutical products with known or potential vulnerabilities to formaldehyde-induced or formic acid-induced degradation or gelatin cross-linking were subjected to accelerated stability challenges in the presence and absence of activated carbon. The effects of time and storage conditions were determined. For all of the products studied, activated carbon attenuated drug degradation or gelatin cross-linking. This novel use of activated carbon in pharmaceutical packaging may be useful for enhancing the chemical stability of drug products or the dissolution stability of gelatin-containing dosage forms and may allow for the 1) extension of a drug product's shelf-life when the limiting attribute is a degradation product induced by a reactive impurity, 2) marketing of a drug product in hotter and more humid climatic zones than currently supported without the use of activated carbon, and 3) enhanced dissolution stability of products that are vulnerable to gelatin cross-linking.

The hidden practices and experiences of healthcare practitioners dealing with fuel poverty.
Mc Conalogue, D; Kierans, C; Moran, A
2016-06-01
Fuel poverty negatively impacts a population's health affecting life chances along the life course. Moreover, it represents a substantial inequality in the UK. Healthcare practitioners (HCPs) have a key role in identifying and supporting patients who are fuel poor. A qualitative inquiry with District Nurses and General Practitioners, to explore their understanding and experiences of dealing with patients living in fuel poverty. Participants recognize fuel poverty by observing material cues. They perceive their relationship with the patient as pivotal to recognizing the fuel poor. Practitioners' sense of responsibility for their patients' social concerns is determined by their knowledge about the link to health outcomes. The services that they sign-post to are motivated by their experience dealing with the service, or their patients' experiences of the service. Participants' reliance on temporary material cues resulted in few experiences of recognition of the fuel poor. HCPs' perceptions of patient pride and the lack of personal relationship between doctor and patient presented barriers to identifying fuel poor patients. A limitation of this study is the small sample size of nine participants. These came from two professional groups, which afforded more depth of exploration, but may limit applicability to other professionals. © The Author 2015.

People with suspected breast cancer who are not referred for diagnostic testing remain unregistered and are not included in cancer statistics. Little is known about the extent of and motivation for nonreferral of these patients. A Web-based survey was sent to all elderly care physicians (ECPs) registered at the National Association of Elderly Care Physicians and Social Geriatricians in the Netherlands, inquiring about the number of patients with suspected breast cancer they encountered and subsequent choices regarding referral. Surveys were completed by 419 (34%) of 1239 ECPs; 249 (60%) of these had encountered one or more patients with suspected breast cancer in the past year. Seventy-four (33%) ECPs reported not referring the last patient. Reasons for nonreferral were end-stage dementia (57%), patient/family preference (29%), and limited life expectancy (23%). Referral was frequently thought to be too burdensome (13%). For 16% of nonreferred patients, hormonal treatment was started by the ECP without diagnostic confirmation of cancer. In this survey, more than 33% of nursing home patients with suspected breast cancer were not referred for further testing, in particular those with advanced dementia, limited life expectancy, and poor functional status. As the combination of dementia and suspected breast cancer is expected to double in the coming decades, now is the time to optimize cancer care for these vulnerable patients.

Revisiting the safety of aspartame.
Choudhary, Arbind Kumar; Pretorius, Etheresia
2017-09-01
Aspartame is a synthetic dipeptide artificial sweetener, frequently used in foods, medications, and beverages, notably carbonated and powdered soft drinks. Since 1981, when aspartame was first approved by the US Food and Drug Administration, researchers have debated both its recommended safe dosage (40 mg/kg/d) and its general safety to organ systems. This review examines papers published between 2000 and 2016 on both the safe dosage and higher-than-recommended dosages and presents a concise synthesis of current trends. Data on the safe aspartame dosage are controversial, and the literature suggests there are potential side effects associated with aspartame consumption. Since aspartame consumption is on the rise, the safety of this sweetener should be revisited. Most of the literature available on the safety of aspartame is included in this review. Safety studies are based primarily on animal models, as data from human studies are limited. The existing animal studies and the limited human studies suggest that aspartame and its metabolites, whether consumed in quantities significantly higher than the recommended safe dosage or within recommended safe levels, may disrupt the oxidant/antioxidant balance, induce oxidative stress, and damage cell membrane integrity, potentially affecting a variety of cells and tissues and causing a deregulation of cellular function, ultimately leading to systemic inflammation. © The Author(s) 2017.

Iron and malaria: a dangerous liaison?
Moya-Alvarez, Violeta; Bodeau-Livinec, Florence; Cot, Michel
2016-10-01
Malaria increases the burden of anemia in low-income countries, where, according to 2012 data from the World Health Organization, 40% of children are anemic. Moreover, iron is a cofactor for Plasmodium falciparum development, raising fears that iron supplementation might be harmful in patients with P. falciparum infection. The primary objective of this narrative review is to describe current knowledge on the iron-malaria association, including recent findings and substantive qualitative results. Between 2012 and 2016 the MEDLINE database was searched for literature published about malaria and iron levels. Observational studies reported some protection of iron supplementation against malaria among iron-deficient children, while older clinical trials reported increased susceptibility to malaria among iron-supplemented children. However, iron supplements were not significantly associated with increased malaria risk in recent clinical trials or in a 2016 Cochrane review. Evidence of an iron-malaria association is limited by the following factors: the protective effect of control interventions, the limited follow-up of children, and the lack of homogenous iron indicators. The effects of previous health status and possible thresholds in iron levels should be investigated using a gold-standard combination of iron markers. Moreover, the benefits of iron supplementation require further evaluation. © The Author(s) 2016. Published by Oxford University Press on behalf of the International Life Sciences Institute.

Airway surface liquid homeostasis in cystic fibrosis: pathophysiology and therapeutic targets.
Haq, Iram J; Gray, Michael A; Garnett, James P; Ward, Christopher; Brodlie, Malcolm
2016-03-01
Cystic fibrosis (CF) is a life-limiting disease characterised by recurrent respiratory infections, inflammation and lung damage. The volume and composition of the airway surface liquid (ASL) are important in maintaining ciliary function, mucociliary clearance and antimicrobial properties of the airway. In CF, these homeostatic mechanisms are impaired, leading to a dehydrated and acidic ASL. ASL volume depletion in CF is secondary to defective anion transport by the abnormal cystic fibrosis transmembrane conductance regulator protein (CFTR). Abnormal CFTR mediated bicarbonate transport creates an unfavourable, acidic environment, which impairs antimicrobial function and alters mucus properties and clearance. These disease mechanisms create a disordered airway milieu, consisting of thick mucopurulent secretions and chronic bacterial infection. In addition to CFTR, there are additional ion channels and transporters in the apical airway epithelium that play a role in maintaining ASL homeostasis. These include the epithelial sodium channel (ENaC), the solute carrier 26A (SLC26A) family of anion exchangers, and calcium-activated chloride channels. In this review we discuss how the ASL is abnormal in CF and how targeting these alternative channels and transporters could provide an attractive therapeutic strategy to correct the underlying ASL abnormalities evident in CF.

To evaluate quality of life and patients' satisfaction in transsexual patients (TS) after sex reassignment operation compared with healthy controls. A case-control study. A tertiary referral center. Patients after sex reassignment operation were compared with a similar group of healthy controls in respect to quality of life and general satisfaction. For quality of life we used the King's Health Questionnaire, which was distributed to the patients and to the control group. Visual analogue scale was used for the determination of satisfaction. Main outcome measures were quality of life and satisfaction. Fifty-five transsexuals participated in this study. Fifty-two were male-to-female and 3 female-to-male. Quality of life as determined by the King's Health Questionnaire was significantly lower in general health, personal, physical and role limitations. Patients' satisfaction was significantly lower compared with controls. Emotions, sleep, and incontinence impact as well as symptom severity is similar to controls. Overall satisfaction was statistically significant lower in TS compared with controls. Fifteen years after sex reassignment operation quality of life is lower in the domains general health, role limitation, physical limitation, and personal limitation.

Participation in regular physical activity is associated with a multitude of health benefits across the life course. However, many people fail to meet PA recommendations. Despite a plethora of studies, the evidence regarding the environmental (physical) determinants of physical activity remains inconclusive. To identify the physical environmental determinants that influence PA across the life course. An online systematic literature search was conducted using MEDLINE, ISI Web of Science, Scopus and SPORTDiscus. The search was limited to studies published in English (January 2004 to April 2016). Only systematic literature reviews (SLRs) and meta-analyses (MAs) of observational studies, that investigated the association between physical determinants and physical activity outcomes, were eligible for inclusion. The extracted data were assessed on the importance of determinants, strength of evidence and methodological quality. The literature search identified 28 SLRs and 3 MAs on 67 physical environmental characteristics potentially related to physical activity that were eligible for inclusion. Among preschool children, a positive association was reported between availability of backyard space and outdoor toys/equipment in the home and overall physical activity. The availability of physical activity programs and equipment within schools, and neighbourhood features such as pedestrian and cyclist safety structure were positively associated with physical activity in children and adolescents. Negative street characteristics, for example, lack of sidewalks and streetlights, were negatively associated with physical activity in adults. Inconsistent associations were reported for the majority of reviewed determinants in adults. This umbrella SLR provided a comprehensive overview of the physical environment determinants of physical activity across the life course and has highlighted, particularly amongst youth, a number of key determinants that may be associated with overall physical activity. Given the limited evidence drawn mostly from cross-sectional studies, longitudinal studies are needed to further explore these associations. PROSPERO CRD42015010616.

Cancer cachexia negatively impacts cancer-related treatment options, quality of life, morbidity, and mortality, yet no established therapies exist. We investigated the anabolic properties of testosterone to limit the loss of body mass in late stage cancer patients undergoing standard of care cancer treatment. A randomized, double-blind, placebo-controlled phase II clinical trial was undertaken to assess the potential therapeutic role of adjunct testosterone to limit loss of body mass in patients with squamous cell carcinoma of the cervix or head and neck undergoing standard of care treatment including chemotherapy and chemoradiation. Patients were randomly assigned in blocks to receive weekly injections of either 100 mg testosterone enanthate or placebo for 7 weeks. The primary outcome was per cent change in lean body mass, and secondary outcomes included assessment of quality of life, tests of physical performance, muscle strength, daily activity levels, resting energy expenditure, nutritional intake, and overall survival. A total of 28 patients were enrolled, 22 patients were studied to completion, and 21 patients were included in the final analysis (12 placebo, nine testosterone). Adjunct testosterone increased lean body mass by 3.2% (95% confidence interval [CI], 0-7%) whereas those receiving placebo lost 3.3% (95% CI, -7% to 1%, P = 0.015). Although testosterone patients maintained more favourable body condition, sustained daily activity levels, and showed meaningful improvements in quality of life and physical performance, overall survival was similar in both treatment groups. In patients with advanced cancer undergoing the early phase of standard of care therapy, adjunct testosterone improved lean body mass and was also associated with increased quality of life, and physical activity compared with placebo. © 2018 The Authors.

To what extent does terrestrial life "follow the water"?
Jones, Eriita G; Lineweaver, Charles H
2010-04-01
Terrestrial life is known to require liquid water, but not all terrestrial water is inhabited. Thus, liquid water is a necessary, but not sufficient, condition for life. To quantify the terrestrial limits on the habitability of water and help identify the factors that make some terrestrial water uninhabited, we present empirical pressure-temperature (P-T) phase diagrams of water, Earth, and terrestrial life. Eighty-eight percent of the volume of Earth where liquid water exists is not known to host life. This potentially uninhabited terrestrial liquid water includes (i) hot and deep regions of Earth where some combination of high temperature (T > 122 degrees C) and restrictions on pore space, nutrients, and energy is the limiting factor and (ii) cold and near-surface regions of Earth, such as brine inclusions and thin films in ice and permafrost (depths less than approximately 1 km), where low temperatures (T < -40 degrees C), low water activity (a(w) < 0.6), or both are the limiting factors. If the known limits of terrestrial life do not change significantly, these limits represent important constraints on our biosphere and, potentially, on others, since approximately 4 billion years of evolution have not allowed life to adapt to a large fraction of the volume of Earth where liquid water exists.
Requirements and limits for life in the context of exoplanets
McKay, Christopher P.
2014-01-01
The requirements for life on Earth, its elemental composition, and its environmental limits provide a way to assess the habitability of exoplanets. Temperature is key both because of its influence on liquid water and because it can be directly estimated from orbital and climate models of exoplanetary systems. Life can grow and reproduce at temperatures as low as −15 °C, and as high as 122 °C. Studies of life in extreme deserts show that on a dry world, even a small amount of rain, fog, snow, and even atmospheric humidity can be adequate for photosynthetic production producing a small but detectable microbial community. Life is able to use light at levels less than 10−5 of the solar flux at Earth. UV or ionizing radiation can be tolerated by many microorganisms at very high levels and is unlikely to be life limiting on an exoplanet. Biologically available nitrogen may limit habitability. Levels of O2 over a few percent on an exoplanet would be consistent with the presence of multicellular organisms and high levels of O2 on Earth-like worlds indicate oxygenic photosynthesis. Other factors such as pH and salinity are likely to vary and not limit life over an entire planet or moon. PMID:24927538

To test whether a long term, structured physical activity program compared with a health education program reduces the risk of serious fall injuries among sedentary older people with functional limitations. Multicenter, single blinded randomized trial (Lifestyle Interventions and Independence for Elders (LIFE) study). Eight centers across the United States, February 2010 to December 2011. 1635 sedentary adults aged 70-89 years with functional limitations, defined as a short physical performance battery score ≤ 9, but who were able to walk 400 m. A permuted block algorithm stratified by field center and sex was used to allocate interventions. Participants were randomized to a structured, moderate intensity physical activity program (n=818) conducted in a center (twice a week) and at home (3-4 times a week) that included aerobic, strength, flexibility, and balance training activities, or to a health education program (n=817) consisting of workshops on topics relevant to older people and upper extremity stretching exercises. Serious fall injuries, defined as a fall that resulted in a clinical, non-vertebral fracture or that led to a hospital admission for another serious injury, was a prespecified secondary outcome in the LIFE Study. Outcomes were assessed every six months for up to 42 months by staff masked to intervention assignment. All participants were included in the analysis. Over a median follow-up of 2.6 years, a serious fall injury was experienced by 75 (9.2%) participants in the physical activity group and 84 (10.3%) in the health education group (hazard ratio 0.90, 95% confidence interval 0.66 to 1.23; P=0.52). These results were consistent across several subgroups, including sex. However, in analyses that were not prespecified, sex specific differences were observed for rates of all serious fall injuries (rate ratio 0.54, 95% confidence interval 0.31 to 0.95 in men; 1.07, 0.75 to 1.53 in women; P=0.043 for interaction), fall related fractures (0.47, 0.25 to 0.86 in men; 1.12, 0.77 to 1.64 in women; P=0.017 for interaction), and fall related hospital admissions (0.41, 0.19 to 0.89 in men; 1.10, 0.65 to 1.88 in women; P=0.039 for interaction). In this trial, which was underpowered to detect small, but possibly important reductions in serious fall injuries, a structured physical activity program compared with a health education program did not reduce the risk of serious fall injuries among sedentary older people with functional limitations. These null results were accompanied by suggestive evidence that the physical activity program may reduce the rate of fall related fractures and hospital admissions in men.Trial registration ClinicalsTrials.gov NCT01072500.

Annual species may increase reproduction by increasing adult body size through extended development, but risk being unable to complete development in seasonally limited environments. Synthetic reviews indicate that most, but not all, species have responded to recent climate warming by advancing the seasonal timing of adult emergence or reproduction. Here, we show that 50 years of climate change have delayed development in high-elevation, season-limited grasshopper populations, but advanced development in populations at lower elevations. Developmental delays are most pronounced for early-season species, which might benefit most from delaying development when released from seasonal time constraints. Rearing experiments confirm that population, elevation and temperature interact to determine development time. Population differences in developmental plasticity may account for variability in phenological shifts among adults. An integrated consideration of the full life cycle that considers local adaptation and plasticity may be essential for understanding and predicting responses to climate change. © 2015 The Author(s) Published by the Royal Society.

The Arabidopsis thaliana aquaporin AtPIP1;2 is a physiologically relevant CO₂ transport facilitator.
Heckwolf, Marlies; Pater, Dianne; Hanson, David T; Kaldenhoff, Ralf
2011-09-01
Cellular exchange of carbon dioxide (CO₂) is of extraordinary importance for life. Despite this significance, its molecular mechanisms are still unclear and a matter of controversy. In contrast to other living organisms, plants are physiologically limited by the availability of CO₂. In most plants, net photosynthesis is directly dependent on CO₂ diffusion from the atmosphere to the chloroplast. Thus, it is important to analyze CO₂ transport with regards to its effect on photosynthesis. A mutation of the Arabidopsis thaliana AtPIP1;2 gene, which was characterized as a non-water transporting but CO₂ transport-facilitating aquaporin in heterologous expression systems, correlated with a reduction in photosynthesis under a wide range of atmospheric CO₂ concentrations. Here, we could demonstrate that the effect was caused by reduced CO₂ conductivity in leaf tissue. It is concluded that the AtPIP1;2 gene product limits CO₂ diffusion and photosynthesis in leaves. © 2011 The Authors. The Plant Journal © 2011 Blackwell Publishing Ltd.
Prospective audit to evaluate the potential of the coronial system to increase solid organ donation.

Anecdotal evidence suggests that organ donation from deceased donors referred to the Coroner/Procurator Fiscal (PF) could be increased if all followed best practice. The aim of this prospective audit was to establish how referrals affected organ donation and to develop evidence-based guidelines to ensure that organ donation can be facilitated safely without interfering in the Coroner/PF's investigative process. Prospective audit. All acute National Health Service Hospitals in the UK where deceased organ donation was considered. 1437 deceased patients who met the eligibility criteria for organ donation and were referred to Coroner/PF. Number of cases where permission for transplantation was given, number of organs where permission was refused and number of organs which might have been transplanted if all had followed best practice. Full permission for organ retrieval was given in 87% cases and partial permission in 9%. However, if full permission had been given where no autopsy was performed or restrictions seemed unjustified, up to 77 organs (22 lungs, 22 kidneys, 9 pancreases, 9 livers, 8 hearts and 7 small bowels) could have been available for transplant. Coroners/PFs and their officers show strong support for transplantation but improvement in practice could result in a small but significant increase in life-saving and life-enhancing transplants.

Traumatic brain injury (TBI) is a major cause of death and disability and may cause transient or persistent, isolated or multiple hypopituitarism in a variable percentage of cases. The primary aim of this study was to determine the incidence of isolated and multiple anterior pituitary hormone deficiency in subjects with TBI in a single institution. The secondary aim was to determine a correlation between pituitary deficiency and quality of life (QOL) after TBI. Thirty-five patients, aged between 18 and 63 years, were evaluated 6months to 5 years after TBI. We evaluated the QOL by SF-12(®) questionnaire and measured serum basal GH, IGF1, LH, FSH, testosterone (in males), 17-β-estradiol (in women), PRL, fT4 and TSH. In patients with low IGF1, a GHRH + Arginine test was performed. Single or multiple pituitary failure was found in 13 patients (37%). Low testosterone was found in 7 males, low FSH and/or LH in 4, low IGF1 in 7 patients. Hypogonadotropic hypogonadism and GH insufficiency assessed by GHRH + Arginine test were found respectively in 3 and 2 patients. One patient displayed a concomitant GH insufficiency and low TSH level. Twenty six patients showed a reduction in QOL. A correlations between altered QOL and hormonal deficiency was not observed. Isolated or multiple hypopituitarism resulting from TBI are frequent. Alterations in QOL and pituitary function resulting from TBI are not associated. Copyright © 2015 IJS Publishing Group Limited.

Autobiographical memory, central in human cognition and every day functioning, enables past experienced events to be remembered. A variety of disorders affecting autobiographical memory are characterized by the difficulty of retrieving specific detailed memories of past personal events. Owing to the impact of autobiographical memory impairment on patients' daily life, it is necessary to better understand these deficits and develop relevant methods to improve autobiographical memory. The primary objective of the present systematic PRISMA review was to give an overview of the first empirical evidence of the potential of wearable cameras in autobiographical memory investigation in remediating autobiographical memory impairments. The peer-reviewed literature published since 2004 on the usefulness of wearable cameras in research protocols was explored in 3 databases (PUBMED, PsycINFO, and Google Scholar). Twenty-eight published studies that used a protocol involving wearable camera, either to explore wearable camera functioning and impact on daily life, or to investigate autobiographical memory processing or remediate autobiographical memory impairment, were included. This review analyzed the potential of wearable cameras for 1) investigating autobiographical memory processes in healthy volunteers without memory impairment and in clinical populations, and 2) remediating autobiographical memory in patients with various kinds of memory disorder. Mechanisms to account for the efficacy of wearable cameras are also discussed. The review concludes by discussing certain limitations inherent to using cameras, and new research perspectives. Finally, ethical issues raised by this new technology are considered.

Basic Life Support (BLS) is a life-saving and fundamental skill in resuscitation. However, studies have reported limitations in BLS training outcomes for both health professional and lay populations, and noted the resource and time-intensive nature of traditional training approaches. This exploratory study evaluated the effectiveness of an interactive CD-based BLS training programme that included unsupervised manikin practice compared with a traditional instructor-led BLS training programme involving demonstration and supervised practice. A quasi-experimental post-test with follow-up design was used. The sample was comprised of two cohorts: Novice second-year undergraduate Nursing students (n=187) and Practising Nurses (n=107) in their first year of hospital employment. BLS skill outcomes were assessed at one week and again at eight weeks post training. No statistically significant differences were found between the CD and traditional instructor-led BLS training methods in BLS skills of Novice and Practising Nurses at one week and eight weeks post training. However, there was a decrement in skill between one week and eight weeks post-training across both groups and an overall low level of competence. The failure to find a difference between the CD-based BLS programme with unsupervised manikin practice and a resource-intensive traditional instructor-led BLS training programme may indicate equivalence of the programmes or, even study design limitations. It is concerning that competence displayed by trainees from both groups was less than optimal and suggests the need for renewed efforts to develop and evaluate BLS training programmes which can achieve high rates of competence with acceptable skill retention over time.

AIMS To assess the pharmacokinetics of vildagliptin at different doses and build a mechanism-based population model that simultaneously describes vildagliptin pharmacokinetics and its effects on DPP-4 activity based on underlying physiology and biology. METHODS Vildagliptin concentrations and DPP-4 activity vs. time from 13 type 2 diabetic patients after oral vildagliptin 10, 25 or 100 mg and placebo twice daily for 28 days were co-modelled. NONMEM VI and S-ADAPT were utilized for population modelling. RESULTS A target-mediated drug disposition (TMDD) model accounting for capacity-limited high affinity binding of vildagliptin to DPP-4 in plasma and tissues had good predictive performance. Modelling the full time course of the vildagliptin-DPP-4 interaction suggested parallel vildagliptin dissociation from DPP-4 by a slow first-order process and hydrolysis by DPP-4 to an inactive metabolite as a disposition mechanism. Due to limited amounts of DPP-4, vildagliptin concentrations increased slightly more than dose proportionally. This newly proposed model and the parameter estimates are supported by published in vitro studies. Mean parameter estimates (inter-individual coefficient of variation) were: non-saturable clearance 36 l h−1 (25%), central volume of distribution 22 l (37%), half-life of dissociation from DPP-4 1.1 h (94%) and half-life of hydrolysis 6.3 h (81%). CONCLUSIONS Vildagliptin is both an inhibitor and substrate for DPP-4. By utilizing the TMDD approach, slow dissociation of vildagliptin from DPP-4 was found in patients and the half-life of hydrolysis by DPP-4 estimated. This model can be used to predict DPP-4 inhibition effects of other dosage regimens and be modified for other DPP-4 inhibitors to differentiate their properties. PMID:22442826
Quantification provides a conceptual basis for convergent evolution.
Speed, Michael P; Arbuckle, Kevin
2017-05-01
While much of evolutionary biology attempts to explain the processes of diversification, there is an important place for the study of phenotypic similarity across life forms. When similar phenotypes evolve independently in different lineages this is referred to as convergent evolution. Although long recognised, evolutionary convergence is receiving a resurgence of interest. This is in part because new genomic data sets allow detailed and tractable analysis of the genetic underpinnings of convergent phenotypes, and in part because of renewed recognition that convergence may reflect limitations in the diversification of life. In this review we propose that although convergent evolution itself does not require a new evolutionary framework, none the less there is room to generate a more systematic approach which will enable evaluation of the importance of convergent phenotypes in limiting the diversity of life's forms. We therefore propose that quantification of the frequency and strength of convergence, rather than simply identifying cases of convergence, should be considered central to its systematic comprehension. We provide a non-technical review of existing methods that could be used to measure evolutionary convergence, bringing together a wide range of methods. We then argue that quantification also requires clear specification of the level at which the phenotype is being considered, and argue that the most constrained examples of convergence show similarity both in function and in several layers of underlying form. Finally, we argue that the most important and impressive examples of convergence are those that pertain, in form and function, across a wide diversity of selective contexts as these persist in the likely presence of different selection pressures within the environment. © 2016 The Authors.

Neonatal and pediatric extracorporeal membrane oxygenation in developing Latin American countries.
Kattan, Javier; González, Álvaro; Castillo, Andrés; Caneo, Luiz Fernando
To review the principles of neonatal-pediatric extracorporeal membrane oxygenation therapy, prognosis, and its establishment in limited resource-limited countries in Latino America. The PubMed database was explored from 1985 up to the present, selecting from highly-indexed and leading Latin American journals, and Extracorporeal Life Support Organization reports. Extracorporeal membrane oxygenation provides "time" for pulmonary and cardiac rest and for recovery. It is used in the neonatal-pediatric field as a rescue therapy for more than 1300 patients with respiratory failure and around 1000 patients with cardiac diseases per year. The best results in short- and long-term survival are among patients with isolated respiratory diseases, currently established as a standard therapy in referral centers for high-risk patients. The first neonatal/pediatric extracorporeal membrane oxygenation Program in Latin America was established in Chile in 2003, which was also the first program in Latin America to affiliate with the Extracorporeal Life Support Organization. New extracorporeal membrane oxygenation programs have been developed in recent years in referral centers in Argentina, Colombia, Brazil, Mexico, Perú, Costa Rica, and Chile, which are currently funding the Latin American Extracorporeal Life Support Organization chapter. The best results in short- and long-term survival are in patients with isolated respiratory diseases. Today extracorporeal membrane oxygenation therapy is a standard therapy in some Latin American referral centers. It is hoped that these new extracorporeal membrane oxygenation centers will have a positive impact on the survival of newborns and children with respiratory or cardiac failure, and that they will be available for an increasing number of patients from this region in the near future.

The purpose of this multiple case study was to compare and contrast older people's and their relatives' experiences of participation in decision-making processes regarding the planning of everyday life after discharge from hospital. Internationally, patient involvement in health services is established to benefit patient health and to improve quality of the services. The literature shows that at hospital discharge, older people would benefit from better communication and more active participation of relatives in the discharge planning. Little research has been carried out on the experiences of patients and relatives as a family in this context, and even less has investigated their participation. This study used a qualitative design with a comparative multicase approach. Participants were recruited from two hospitals in Norway using a purposive sampling strategy. Semi-structured interviews were conducted with five patients and with six of their relatives. Three patterns of experiences were identified: contradicting experiences; consistent experiences of nonpreferred participation; similar, but separate experiences of user participation. User participation in the planning of everyday life following discharge appeared to be random and limited for both patients and their relatives, and conflicting for the families as a whole. The decision-making processes seemed to be limited to the hospital context and did not include the broader context of everyday life following discharge. The results underscore the importance of taking a family perspective when caring for older people. Family meetings might be a useful tool to ensure systematic assessment and integration of the perspectives of both older people and their family in the planning of follow-up care. © 2017 The Authors.

The relation between positive psychological well-being (PPWB) and sexual behaviour is understudied in older adult groups. To examine the relation between PPWB (positive affect and life satisfaction) and sexual behaviour (sexual activity and physical tenderness) in older adults, and whether it is independent from depressive symptoms and uniform across older age groups. Cross-sectional. Community-dwelling adults aged 65 years or older, Rotterdam, The Netherlands. Sexual behaviour, the Cantril Self-Anchoring Striving Scale, the Center for Epidemiological Studies Depression (CES-D) scale and partner status were assessed in 2,373 dementia-free older adults from the Rotterdam Study. For partnered participants, greater positive affect and life satisfaction was associated with more sexual activity and physical tenderness. Although CES-D was negatively associated with sexual behaviour within partnered older adults, there was no association between the negative affect sub-scale and sexual behaviour. The relations were independent of depressive symptoms, physical health and chronic disease status and were observed for both sexes at all older ages. For unpartnered participants, greater life satisfaction and was associated with more physical tenderness. There was low prevalence of sexual behaviour in unpartnered participants, limiting further stratification. Greater PPWB was associated with more sexual behaviour in partnered, community-dwelling older adults. We are the first to demonstrate that sexual behaviour is associated with PPWB, rather than lack of depressive symptoms; and that the association was present at all ages for partnered older adults. Limited conclusions can be drawn for unpartnered older adults as their sexual behaviour was infrequent. © The Author 2016.

With prevalence of noncommunicable diseases and life expectancy rising in Senegal, the need for palliative care is likely growing. No national palliative care needs assessments have been carried out. To assess the capacity and need for palliative care in Senegal. A multicomponent assessment of availability and demand for palliative care was conducted in two tertiary and two regional hospitals in Senegal in 2015 with approval from Senegal's National Ethics Committee for Health Research. The assessment consisted of (1) an inpatient hospital census; (2, 3) surveys of inpatients and outpatients with life-limiting illness; (4) a knowledge, attitudes, and practices survey among health care workers; and (5) a facility survey to assess availability of palliative care medications. Nearly half (44.4%) of all inpatients (n = 167) had an active life-limiting illness. Among them, 56.6% reported moderate-to-severe pain in the past three days, 2.3% of whom received morphine, and 76.7% received weak or no pain medication. Inpatients also experienced moderate-to-severe dyspnea (42.1%), fatigue (66.5%), nausea (16.5%), and drowsiness (42.1%). About 39.2% of all outpatients (n = 395) reported moderate-to-severe pain, and 52.8% reported that the treatment they had received relieved their pain only partially or not at all. Two-thirds of all doctors reported feeling comfortable prescribing pain medicines; however, 83.0% rarely or never prescribed morphine. Two of four hospitals reported no use of morphine in 2014. There is significant need for palliative care in Senegal. Training of health care workers and ensuring availability of relevant medications should be prioritized.

On the decomposition of life expectancy and limits to life.
Mayhew, Les; Smith, David
2015-01-01
Life expectancy is a measure of how long people are expected to live and is widely used as a measure of human development. Variations in the measure reflect not only the process of ageing but also the impacts of such events as epidemics, wars, and economic recessions. Since 1950, the influence of these events in the most developed countries has waned and life expectancy continues to lengthen unabated. As a result, it has become more difficult to forecast long-run trends accurately, or identify possible upper limits. We present new methods for comparing past improvements in life expectancy and also future prospects, using data from five developed, low-mortality countries. We consider life expectancy in 10-year age intervals rather than over the remaining lifetime, and show how natural limits to life expectancy can be used to extrapolate trends. We discuss the implications and compare our approach with other commonly used methods.

The results of the European Randomized Study of Screening for Prostate Cancer (ERSPC) trial showed a statistically significant 29% prostate cancer mortality reduction for the men screened in the intervention arm and a 23% negative impact on the life-years gained because of quality of life. However, alternative prostate-specific antigen (PSA) screening strategies for the population may exist, optimizing the effects on mortality reduction, quality of life, overdiagnosis, and costs. Based on data of the ERSPC trial, we predicted the numbers of prostate cancers diagnosed, prostate cancer deaths averted, life-years and quality-adjusted life-years (QALY) gained, and cost-effectiveness of 68 screening strategies starting at age 55 years, with a PSA threshold of 3, using microsimulation modeling. The screening strategies varied by age to stop screening and screening interval (one to 14 years or once in a lifetime screens), and therefore number of tests. Screening at short intervals of three years or less was more cost-effective than using longer intervals. Screening at ages 55 to 59 years with two-year intervals had an incremental cost-effectiveness ratio of $73000 per QALY gained and was considered optimal. With this strategy, lifetime prostate cancer mortality reduction was predicted as 13%, and 33% of the screen-detected cancers were overdiagnosed. When better quality of life for the post-treatment period could be achieved, an older age of 65 to 72 years for ending screening was obtained. Prostate cancer screening can be cost-effective when it is limited to two or three screens between ages 55 to 59 years. Screening above age 63 years is less cost-effective because of loss of QALYs because of overdiagnosis. © The Author 2014. Published by Oxford University Press. All rights reserved.

Introduction: Rheumatoid arthritis is a chronic autoimmune disorder that leads to joint swelling, stiffness, pain and progressive joint destruction. It is a common disease with prevalence of 1% worldwide that affecting all aspects of patients’ lives. Therefore, this study was conducted to summarize and provide a clear view of quality of life among the patients in Iran through a literature review. Methods: This study was conducted as a literature review over article published between 2000 to 2013, by using data bases comprise of Google scholar, Science Direct, Pubmed, IRANDOC, SID, Medlib, Magiran and by key words: “quality of life”, “rheumatoid arthritis”, “Iran” and their Persian equivalents. Finally 2065 articles assessed and according to the aim of the study are 11 studies synthesized. Extracted results first were summarized in Extraction Table, and then analyzed manually. Results: In reviewed articles rheumatoid arthritis patients’ quality of life was measured by using five different tools, the most important one of them was SF36 questionnaire. Among eight dimensions of SF36 questionnaire, the highest mean according included articles result was social functioning with average score of 63.4 and the lowest for physical limitation (physical role functioning) with score of 43. Overall, mean of eight dimensions was 52.47. The most important factors affecting quality of life were disease severity and pain, depression, income, educational, occupational status, married status, sign of disease, fatigue, anxiety and disease activity scores. Conclusion: The results of the study showed relatively low quality of life of rheumatoid arthritis patients in Iran. Empowering patients by participating them in service delivery process and decision making can improves quality of life and in this regard health care provider must be focused on patient self-care abilities and reinforcing this factor by training them.

The discrepancy between patients' preferred and actual place of death highlights the dilemma inherent in achieving their preferences for home death. Research on determinants of home death has been limited largely by focusing on individual-level factors and somewhat on health care resources at the primary hospital and regional levels. To investigate factors associated with home death, specifically, services received by cancer patients at the end of life (EOL). This was a retrospective cohort study using administrative data from 201,201 Taiwanese cancer decedents in the period 2001-2006. Rates of home death decreased significantly over time (from 35.67% to 32.39%). Dying at home was associated with patient demographics (gender, age, and marital status) and disease characteristics (cancer type, metastatic status, postdiagnosis survival time, and comorbidity level). Taiwanese cancer patients were less likely to die at home if they received care from a medical oncologist and in hospitals or regions with abundant health care resources. Furthermore, Taiwanese cancer patients were less likely to die at home if they used life-sustaining treatments (intensive care unit care, cardiopulmonary resuscitation, intubation, and mechanical ventilation) in the last month of life. However, multiple emergency room visits in the last month of life and receiving hospice care increased Taiwanese cancer patients' propensity to die at home. Despite the causal ambiguity in interpreting our research findings, they indicate that using life-sustaining treatments at EOL not only exacts a substantial toll from patients, family members, and society, but also decreases the likelihood of dying at home.

Increasing disability-free life expectancy among older adults in Palestine from 2006 to 2010.
Brønnum-Hansen, Henrik; Duraidi, Mohammed; Qalalwa, Khaled; Jeune, Bernard

The population of Palestine comprises almost 200 000 Palestinians aged 60 or older. The purpose of the study was to estimate disability-free life expectancy for Palestinians living in the West Bank and Gaza Strip and to evaluate changes from 2006 to 2010. The study combined mortality data and prevalence of activity limitation derived from the Palestinian Family Health Surveys carried out in 2006 and 2010. Based on questions about the ability to perform five basic daily activities, disability-free life expectancy was estimated. Changes between 2006 and 2010 were decomposed into contributions from changes in mortality and disability. Life expectancy at age 60 increased from 17.1 years in 2006 to 17.3 years in 2010 for men and from 18.7 years to 19.0 years for women. Disability-free life expectancy increased significantly, by 1.3 years for 60-year-old men (from 12.8 years to 14.1 years) and 1.8 years for 60-year-old women (from 12.6 years to 14.4 years). This increase was seen in the Gaza Strip as well as in the West Bank. While the modest contribution of the mortality effect did not differ between gender and regions, the strong contributions from the disability effects varied, being greatest for women in the Gaza Strip. The significant increase in disability-free life expectancy for both genders is remarkable and, to our knowledge, not seen in other low-income countries. This change may be due to decreasing incidence of disability and greater recovery from disability as a result of better prevention, care and rehabilitation of chronic diseases. © The Author 2014.

The implantation of defibrillators should not be studied simply on the basis of clinical improvement or quality of life: it is also important to understand the significance, which the recipients attach to the defibrillator and their experiences with it. The aim of this work was, therefore, to determine the experience of Spanish implantable defibrillator recipients. A qualitative phenomenological study. Purposeful sampling of male implantable defibrillator recipients older than 18 years of age attended at the defibrillator consultancy at the Hospital Fuenlabrada or belonging to the Heart Patients' Association (Asociación de Pacientes Coronarios, APACOR). A secondary, theoretical sampling was also carried out to gain a more in-depth understanding of certain aspects identified in the first sampling, such as living with the discharges and difficulties during sexual activity. Data were collected using unstructured and semi-structured questionnaires and applying a question guide, field notes and the recipients' personal diaries/letters. Data collection was terminated once theoretical saturation was reached. Data were analysed using the Giorgi method. Finally, the seven themes, which showed what it means to be an implantable cardioverter-defibrillator recipient, were described. The defibrillator is perceived positively and is considered to be a form of life insurance, whereas the discharges are a limiting factor. The recipient's outlook on life changes. Acceptance of the changes resulting from the implant leads to the development of strategies to facilitate everyday life. An understanding of the significance attached by recipients to their disease, diagnosis and treatment allows their behaviour and expectations to be understood. Provide the basis for nursing assessment after discharge, understand the effects of the device in the recipient and track the process of adapting the recipient to daily life. © 2011 Blackwell Publishing Ltd.

Professor Samuel David Gross (1805-1884) and His Innovations in Surgery and Medicine.
Laios, Konstantinos
2018-06-01
Professor Samuel David Gross (1805-1884) is considered as one of the founders of American surgery. He was a skillful surgeon who could excellently perform a lithotomy, an amputation, and a cataract surgery. He introduced many new surgical techniques and designed new surgical and medical instruments. He expertise was not limited to surgery alone; he also published studies concerning internal medicine, pathology, experimental physiology, and pharmacology. His most important treatise was his 2-volume work, A System of Surgery, Pathological, Diagnostic, Therapeutic and Operative (1861), which was a standard reference book in surgery in the United States during the second half of 19th century. Gross received many honors during his life. He was active in the operating room until his death.
[Oropharyngeal candidiasis and radiotherapy].
Pinel, B; Cassou-Mounat, T; Bensadoun, R-J
2012-05-01
The oropharyngeal candidiasis is a common condition in cancer patients treated by irradiation, during and after their treatment. For example, almost 70% of patients treated with chemoradiation for head and neck cancer are colonized, and 40% of symptomatic patients have an oropharyngeal candidiasis. Furthermore, we noticed an increase in non-albicans Candida strains, which are present in almost 50% of samples. Cancer treatments, especially radiation therapy, and comorbidities are risk factors of oropharyngeal candidiasis. Oropharyngeal candidiasis has substantial effects on quality of life, and may limit treatment. Epidemiologic data, physiopathology, clinical diagnosis criteria, consequences and treatment of oropharyngeal candidiasis will be discussed in this article.

Beyond the sensible world: a discussion of Mark Zuss' The practice of theoretical curiosity
NASA Astrophysics Data System (ADS)
Fellner, Gene; Pitts, Wesley; Zuss, Mark
2012-09-01
In this article, Gene Fellner reviews Mark Zuss's recently published The practice of theoretical curiosity (2012) and provides a synopsis of the book's structure. These two sections are followed by a metalogue in which Mark Zuss, Welsey Pitts, and Fellner discuss curiosity and the conundrum of establishing limits beyond which curiosity should not roam. This is a central theme of Zuss's book, and it is of particular significance today as curiosity, driven by developments in technoscience and transgenics, transforms nature and we who are part of it. Influenced by Merleau-Ponty's phenomenological lens, Zuss discusses how our knowing the world through our senses is entering an uncertain future mediated by curiosity's reach into everyday life.
Roles of nurses and parents caring for hospitalised children.
Bedells, Ella; Bevan, Ann
2016-03-01
This article reviews the literature on nurses' and parents' self-perceived roles when caring for hospitalised children, focusing on research conducted since the Department of Health published the National Service Framework for Children: Standard for Hospital Services in 2003. Three main themes emerge from the review: nurses' perceptions, parents' perceptions, and negotiation. Clarification of what nurses and parents consider to be their respective roles when caring for hospitalised children is a prerequisite for negotiation of those roles. The family's background, life experiences and circumstances influence the effectiveness of negotiation between nurses and parents. The article explores potential barriers to negotiation, including poor communication and failure to provide information. Limitations of the research and the implications for practice are considered.
High dose rivastigmine in the symptom management of Lewy body dementia.
Nour, Joseph Marwan; Chouliaras, Leonidas; Hickey, Lilian
2016-11-29
A man presented in late 2004 at the age of 65 with a decline in memory. He was diagnosed with Lewy body dementia and started on 3 mg rivastigmine a day, which made a marked clinical improvement. He lived with the illness for 10 years, over which time the dose of acetylcholinesterase inhibitors (ChEI) he took rose to two 9.5 mg rivastigmine patches and 7.5 mg donepezil, significantly above British National Formulary (BNF) limits. He demonstrated clear clinical response to ChEI and showed improvements in alertness and functioning. He did not exhibit life-threatening cardiac side effects and his death in 2014 was not related to the ChEI. 2016 BMJ Publishing Group Ltd.
Severe overdosage with the antiepileptic drug oxcarbazepine
van Opstal, J M; Janknegt, R; Cilissen, J; L’Ortije, W H V M; Nel, J E; De Heer, F
2004-01-01
Few published human data are available concerning the acute toxicity of the new antiepileptic drug oxcarbazepine of which the metabolite 10- monohydroxy derivate (MHD) is the pharmacologically effective compound. Two hours after a documented overdosage of more than 100 tablets oxcarbazepine, the serum level of the parent compound was 10-fold higher than the therapeutic dosage (31.6 mg l−1). However, the concentration of MHD, which peaked 7 h after intake, was only twofold higher (59.0 mg l−1). No life-threatening situations occurred and the patient fully recovered. The fact that oxcarbazepine is a prodrug and that the formation of the active MHD metabolite is a rate-limiting process may contribute to the relative low toxicity of the drug in overdose.

Hypoglycemia is an essential issue for diabetic patients and considered a limiting factor in the glycemic management. Heterogeneity of the diseases in Type 2 Diabetes Mellitus can affect the frequency of hypoglycemia, especially when the patient has cardiovascular diseases. There are several factors that lead to hypoglycemia including sulfonylurea therapy, insulin therapy, delaying or missing a meal, physical exercise, or alcohol consumption. Long-term studies reported that repeated hypoglycemia could increase the risk of cardiovascular diseases. During Ramadan fasting, diabetic patients have high incidence of hypoglycemia. Therefore, focused education about hypoglycemia in routine life of diabetic patients and during fasting in Ramadan is important to reduce the complications. Copyright © 2018 Diabetes India.

The Spirit of "Ubuntu" in Children's Palliative Care.
Marston, Joan M
2015-09-01
The concept of "ubuntu," a Nguni word, is found in many southern African cultures and means that we are part of all humanity and we are who we are through our interconnectedness with others. Children with life-limiting conditions often become isolated and take on a new identity in the eyes of others, linked to their illness and treatment. Terms that are used can dehumanize the child. The concept of ubuntu can help the child, the family, and the community to ensure the child remains connected to society. Programs providing palliative care for children often say they feel isolated; ubuntu principles are relevant to effective network development.

Risk-reducing salpingo-oophorectomy (RRSO) is the most effective intervention to prevent ovarian cancer (OC). It is only available to high-risk women with >10% lifetime OC risk. This threshold has not been formally tested for cost-effectiveness. To specify the OC risk thresholds for RRSO being cost-effective for preventing OC in premenopausal women. The costs as well as effects of surgical prevention ('RRSO') were compared over a lifetime with 'no RRSO' using a decision analysis model. RRSO was undertaken in premenopausal women >40 years. The model was evaluated at lifetime OC risk levels: 2%, 4%, 5%, 6%, 8% and 10%. Costs and outcomes are discounted at 3.5%. Uncertainty in the model was assessed using both deterministic sensitivity analysis and probabilistic sensitivity analysis (PSA). Outcomes included in the analyses were OC, breast cancer (BC) and additional deaths from coronary heart disease. Total costs and effects were estimated in terms of quality-adjusted life-years (QALYs); incidence of OC and BC; as well as incremental cost-effectiveness ratio (ICER). Published literature, Nurses Health Study, British National Formulary, Cancer Research UK, National Institute for Health and Care Excellence guidelines and National Health Service reference costs. The time horizon is lifetime and perspective: payer. Premenopausal RRSO is cost-effective at 4% OC risk (life expectancy gained=42.7 days, ICER=£19 536/QALY) with benefits largely driven by reduction in BC risk. RRSO remains cost-effective at >8.2% OC risk without hormone replacement therapy (ICER=£29 071/QALY, life expectancy gained=21.8 days) or 6%if BC risk reduction=0 (ICER=£27 212/QALY, life expectancy gained=35.3 days). Sensitivity analysis indicated results are not impacted much by costs of surgical prevention or treatment of OC/ BC or cardiovascular disease. However, results were sensitive to RRSO utility scores. Additionally, 37%, 61%, 74%, 84%, 96% and 99.5% simulations on PSA are cost-effective for RRSO at the 2%, 4%, 5%, 6%, 8% and 10% levels of OC risk, respectively. Premenopausal RRSO appears to be extremely cost-effective at ≥4% lifetime OC risk, with ≥42.7 days gain in life expectancy if compliance with hormone replacement therapy is high. Current guidelines should be re-evaluated to reduce the RRSO OC risk threshold to benefit a number of at-risk women who presently cannot access risk-reducing surgery.

Benefits of fidelity: does host specialization impact nematode parasite life history and fecundity?
Koprivnikar, J; Randhawa, H S
2013-04-01
The range of hosts used by a parasite is influenced by macro-evolutionary processes (host switching, host-parasite co-evolution), as well as 'encounter filters' and 'compatibility filters' at the micro-evolutionary level driven by host/parasite ecology and physiology. Host specialization is hypothesized to result in trade-offs with aspects of parasite life history (e.g. reproductive output), but these have not been well studied. We used previously published data to create models examining general relationships among host specificity and important aspects of life history and reproduction for nematodes parasitizing animals. Our results indicate no general trade-off between host specificity and the average pre-patent period (time to first reproduction), female size, egg size, or fecundity of these nematodes. However, female size was positively related to egg size, fecundity, and pre-patent period. Host compatibility may thus not be the primary determinant of specificity in these parasitic nematodes if there are few apparent trade-offs with reproduction, but rather, the encounter opportunities for new host species at the micro-evolutionary level, and other processes at the macro-evolutionary level (i.e. phylogeny). Because host specificity is recognized as a key factor determining the spread of parasitic diseases understanding factors limiting host use are essential to predict future changes in parasite range and occurrence.

Health-related quality of life (HRQoL) is an important measure to evaluate a child's reported treatment experience. Although there are numerous studies of HRQoL in children undergoing curative cancer treatment, there is limited literature on factors that influence this. To review published studies that describe the HRQoL and associated factors in children undergoing curative cancer treatment. Full-text publications in English from January 2005 to March 2013 were searched in PubMed, PsychINFO, and CINAHL for children ≤18 years of age undergoing curative cancer treatment. HRQoL-associated factors were categorized as cancer diagnosis, treatment, child, family, and community. Twenty-six studies met the inclusion criteria. The most frequently used generic and cancer-specific instruments were PedsQL (Pediatric Quality of Life Inventory) Generic and PedsQL Cancer, respectively. Cancer diagnosis and treatment were the most frequently identified variables; fewer studies measured family and community domains. Gender, treatment intensity, type of cancer treatments, time in treatment, and cancer diagnosis were correlated with HRQoL. Our study highlights the need to develop interventions based on diagnosis and treatment regimen to improve the HRQoL in children undergoing curative cancer treatment. © 2015 by Association of Pediatric Hematology/Oncology Nurses.
Why has Not There been More Research of Concern?
Rappert, Brian
2014-01-01
Amid the renewed concern in the last several years about the potential for life science research to facilitate the spread of disease, a central plank of the policy response has been to enact processes for assessing the risks and benefits of "research of concern." The recent controversy regarding a proposed redaction of work on the modification of a H5N1 avian influenza virus is perhaps the most prominent such instance. And yet, a noteworthy feature of this case is its exceptionalness. In the last 10 years, life science publishers, funders, and labs have rarely identified any research as "of concern," let alone proposed censors. This article takes this experience with risk assessment as an invitation for reflection. Reasons for the low number of instances of concern are related to how the biosecurity dimensions of the life sciences are identified, how they are described, how the assessments of benefits and risks are undertaken, how value considerations do and do not enter into assessments, as well as the lack of information on the outcomes of reviews. This argument builds on such considerations to examine the limitations and implications of the risk-benefit experiment of concern framing, the politics of expertise as well as the prospects for alternative responses.

The early life origin theory in the development of cardiovascular disease and type 2 diabetes.
Lindblom, Runa; Ververis, Katherine; Tortorella, Stephanie M; Karagiannis, Tom C
2015-04-01
Life expectancy has been examined from a variety of perspectives in recent history. Epidemiology is one perspective which examines causes of morbidity and mortality at the population level. Over the past few 100 years there have been dramatic shifts in the major causes of death and expected life length. This change has suffered from inconsistency across time and space with vast inequalities observed between population groups. In current focus is the challenge of rising non-communicable diseases (NCD), such as cardiovascular disease and type 2 diabetes mellitus. In the search to discover methods to combat the rising incidence of these diseases, a number of new theories on the development of morbidity have arisen. A pertinent example is the hypothesis published by David Barker in 1995 which postulates the prenatal and early developmental origin of adult onset disease, and highlights the importance of the maternal environment. This theory has been subject to criticism however it has gradually gained acceptance. In addition, the relatively new field of epigenetics is contributing evidence in support of the theory. This review aims to explore the implication and limitations of the developmental origin hypothesis, via an historical perspective, in order to enhance understanding of the increasing incidence of NCDs, and facilitate an improvement in planning public health policy.
Duchenne and Becker muscular dystrophy in adolescents: current perspectives
Andrews, Jennifer G; Wahl, Richard A
2018-01-01
Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) are life-limiting and progressive neuromuscular conditions with significant comorbidities, many of which manifest during adolescence. BMD is a milder presentation of the condition and much less prevalent than DMD, making it less represented in the literature, or more severely affected individuals with BMD may be subsumed into the DMD population using clinical cutoffs. Numerous consensus documents have been published on the clinical management of DMD, the most recent of which was released in 2010. The advent of these clinical management consensus papers, particularly respiratory care, has significantly increased the life span for these individuals, and the adolescent years are now a point of transition into adult lives, rather than a period of end of life. This review outlines the literature on DMD and BMD during adolescence, focusing on clinical presentation during adolescence, impact of living with a chronic illness on adolescents, and the effect that adolescents have on their chronic illness. In addition, we describe the role that palliative-care specialists could have in improving outcomes for these individuals. The increasing proportion of individuals with DMD and BMD living into adulthood underscores the need for more research into interventions and intracacies of adolescence that can improve the social aspects of their lives.

The Impact of Kidney Development on the Life Course: A Consensus Document for Action.
2017-01-01
Hypertension and chronic kidney disease (CKD) have a significant impact on global morbidity and mortality. The Low Birth Weight and Nephron Number Working Group has prepared a consensus document aimed to address the relatively neglected issue for the developmental programming of hypertension and CKD. It emerged from a workshop held on April 2, 2016, including eminent internationally recognized experts in the field of obstetrics, neonatology, and nephrology. Through multidisciplinary engagement, the goal of the workshop was to highlight the association between fetal and childhood development and an increased risk of adult diseases, focusing on hypertension and CKD, and to suggest possible practical solutions for the future. The recommendations for action of the consensus workshop are the results of combined clinical experience, shared research expertise, and a review of the literature. They highlight the need to act early to prevent CKD and other related noncommunicable diseases later in life by reducing low birth weight, small for gestational age, prematurity, and low nephron numbers at birth through coordinated interventions. Meeting the current unmet needs would help to define the most cost-effective strategies and to optimize interventions to limit or interrupt the developmental programming cycle of CKD later in life, especially in the poorest part of the world. © 2017 The Author(s) Published by S.
