The purpose of this research was to examine how oncologists, nurses, and social workers identify suicidality in cancer patients. Sixty-one healthcare professionals (23 oncologists, 18 social workers, and 20 nurses) at two academic cancer centers were interviewed using an in-depth interview guide. This was a qualitative study based on grounded theory methodology. Analysis involved line-by-line coding, with categories and themes emerging from participants' narratives. Suicidality in cancer patients exists on a wide spectrum that ranges from an active will to live to an active will to die. Four phases were identified that included: (A) a strong will to live expressed in themes of active treatments, seeking second opinions, overtreatment, and alternative treatments; (B) a decreasing will to live indicated in themes of mental health distress and physical pain and suffering; (C) a readiness to die expressed in themes of mental health distress, previous mental health diagnoses, physical pain, avoiding more suffering, preserving quality of life in old age, nearing end of life, lack of social support, and maintaining a sense of control; and (D) a will to die indicated in themes of euthanasia and active suicidality. Suicidality in cancer patients exists on a continuum. Cancer patients fluctuate on this spectrum depending on circumstances such as degree of suffering, their personalities and life circumstances, and whether they are nearing the end of life. Results of the study emphasize the need to collect more context specific data on suicidality among cancer patients and the importance of early integration of psychosocial and palliative care in the cancer treatment trajectory.

'Round-table' ethical debate: is a suicide note an authoritative 'living will'?

Living wills are often considered by physicians who are faced with a dying patient. Although popular with the general public, they remain problems of authenticity and authority. It is difficult for the examining physician to know whether the patient understood the terms of the advance directive when they signed it, and whether they still consider it authoritative at the time that it is produced. Also, there is little consensus on what spectrum of instruments constitutes a binding advance directive in real life. Does a 'suicide note' constitute an authentic and authoritative 'living will'? Our panel of authorities considers this problem in a round-table discussion.

Living Wills in Italy: Ethical and Comparative Law Approaches.

PubMed

Veshi, Denard; Neitzke, Gerald

2015-03-01

In this article, advance directives will be analysed through ethical and comparative law approaches. Their importance, the two different types of advance directives and the so-called three steps hierarchy, will be discussed. Living wills will be treated in detail, considering the criticism they have attracted, as well as their known benefits. A thorough examination of the latest version of Arts. 3 and 4 of Italian Bill No. 2350, as approved by the Italian Senate in March 2009 and then amended by the Chamber of Deputies in July 2011, is included. This bill grants advance directives advisory force, limits their application in time and does not allow the validity of oral declarations. This political decision limits autonomy. Furthermore, there are doubts about the constitutionality of this bill, especially with respect to Arts. 2, 13 and 32 of the Italian Constitution, related to the right of self-determination. Further, this article will include a comparative approach of the legal aspects, with particular attention to the French and German models. To conclude, some ethical principles that the Italian legislator must take into consideration are indicated. In addition, some possible modifications of this Bill are suggested based on the experience of other European legislation.

The importance of living wills and advance directives.

PubMed

Alfonso, Heather

2009-10-01

Living wills and advance directives are important components of patients' medical records, which all too often do not indicate the appropriate palliative care measures the patient desires. A review of the current literature indicates that approximately 85% to 95% of the population does not have adequate advance directives or palliative care measures written in their medical record. Furthermore, these orders may not follow the patient when he or she is transferred to other facilities for intermittent care. Unwanted tracheal intubations can be both costly to the facility and distressing to the patient and family members. By instituting a change in policy, organizations can ensure that patients' wishes for end-of-life care are met appropriately. In addition, nurses should advocate for a centralized database at the political level. Copyright 2009, SLACK Incorporated.

An international smoking ban-how many lives will be saved?

PubMed

Kelleher, Cecily C; Frazer, Kate

2014-06-01

Multicomponent tobacco control strategies are crucial to combat the ongoing global smoking challenge. In the twenty-first century, many countries have signed up to the World Health Organization Framework Convention on Tobacco Control, and in recent years a mounting number of countries and regions have implemented partial or complete smoking bans to protect the general public from passive smoke exposure. There is substantial evidence that workers, particularly in the hospitality sector, benefit from reduced exposure. More recently, several reports have appeared from different countries showing a temporal relationship between the introduction of a smoking ban and reduced hospital admissions for cardiovascular, respiratory and maternity outcomes. This will have a measurable benefit for public health, saving many lives. Multicomponent strategies could also reduce active smoking significantly if successfully implemented worldwide.

Adding constitutional depravation to untimely death: South Dakota's living will pregnancy provision.

PubMed

Matchan, H E; Sheffield, K E

1992-01-01

In 1991, the South Dakota Legislature enacted a living will statute. Included is a pregnancy provision that prevents pregnant women from obtaining the full benefit of the statute. A South Dakota Attorney General's opinion was released discussing the conflict of laws problems posed by the statute. That opinion, however, did not address the more important question of the constitutionality of the pregnancy provision. This comment analyzes the pregnancy provision under the Due Process, Equal Protection, and the Establishment Clauses and concludes that South Dakota's pregnancy provision is unconstitutional under all three doctrines.

Clinical ethics case report: questionable capacity and the guidance of living wills.

VanderWalde, Ari

2011-01-01

After falling from a roof, an older man lost neurological function below his face. In two days, the patient regained consciousness, but it was unclear whether he could communicate his preferences, whether due to injuries or difficulties with language. His family believed he could communicate with them, and that he was capable of making treatment decisions. The staff did not think to contact the hospital's largely inactive ethics consultation service for assistance, and instead looked to the patient's living will for guidance, even though the patient was not terminally ill, and his lack of capacity had not been determined.

This study examined whether participants with low somatization (no bodily manifestations of anxiety) who are assumed to identify with- and be inspired- by the Olympic-Games-spirit will present a stronger association between their Olympic-game viewing hours and their will-to-live, than persons with high somatization. One hundred and thirty seven participants reported their daily Olympic-game viewing hours, somatization and will-to-live levels. Results show that while among those with low somatization symptoms level, the relationships between Olympic game viewing hours and will-to-live was positive, the opposite was found among those with high somatization symptoms level. Viewing the Olympic Games may be beneficial for individuals with low somatization level but less so to individuals with higher somatization. Copyright © 2017 Elsevier B.V. All rights reserved.

Clinicians may feel conflicted when a patient's legal decision maker is making decisions that seem inconsistent with a patient's living will. We provide evidence-based information to help clinicians consider whether a surrogate's inconsistent decisions are ethically appropriate. Surrogates are not flawless translators of their loved one's preferences; they are influenced by their own hopes and the current clinical context. Patients may be aware of this, are often concerned about burdening their loved ones, and often grant their surrogates leeway in interpreting their wishes. When appropriate, clinicians should respect surrogates' interpretations of patient values and take steps to decrease surrogate stress during the decision-making process. Finally, if clinicians are cognizant of their own values and preferences, they may recognize how these may affect their responses to certain clinical cases.

Vaccine supply chains need to be better funded and strengthened, or lives will be at risk.

PubMed

Kaufmann, Judith R; Miller, Roger; Cheyne, James

2011-06-01

In the next decade, at least twelve additional vaccines that target such diseases as typhoid, malaria, and dengue will become available to lower- and middle-income countries. These vaccines must travel along what are called supply chains, which include all personnel, systems, equipment, and activities involved in ensuring that vaccines are effectively delivered from the point of production to the people who need them. But for various reasons, supply chains are already strained in many developing countries, and the potential inability to distribute new vaccines will place lives at risk. Among the many steps needed to strengthen the global vaccine supply chain, we suggest that the international community pursue improved coordination between organizations that donate and ship vaccines and the host-country officials who receive and distribute the vaccines, as well as better training for supply-chain managers.

Influences of Nationalism and Historical Traumatic Events on the Will-to-Live of Elderly Israelis.

Carmel, Sara; Granek, Leeat; Zamir, Alon

2016-08-01

Existing research suggests that will-to-live (WTL) is an indicator of subjective well-being (SWB), and that similar personal variables including physical and mental health, quality-of-life, and sociodemographic characteristics influence elderly people's WTL. The purpose of this qualitative study was to explore additional factors which influence older persons' WTL. Twenty-five elderly Israelis across the country were interviewed about what weakens and strengthens their WTL. The grounded theory method guided the data collection and analysis. In addition to the previously reported aspects influencing WTL, analysis resulted in two new categories: nationalism and historical traumatic events. Negative influences of nationalism-related emotions on participants' WTL included themes of disappointment with the state, with children leaving the state, and with existential insecurity. Among the positive influences on WTL, participants mentioned pride in the state and in its development, personal security, and hope for a peaceful future. Under the category of historical traumatic events, participants reported posttraumatic stress and war anxieties, as well as satisfaction and revenge in continued existence, and appreciation for life in Israel compared with life before immigrating to Israel. Our findings indicate that nationalism and feelings of personal involvement in national developments play an important role in the lives of elderly Israelis to the degree that they contribute to their SWB and motivation to continue living. Practitioners and family members can intentionally arouse and strengthen positive nationalistic feelings in the elderly as a way to maintain and promote SWB and WTL. © The Author 2015.

To identify the underlying interests of the Living Will Declaration (LWD) process and to determine the consensus, using a questionnaire, of the knowledge and attitudes of health professionals. A study was performed in two phases using a Delphi technique with a Rand method. 1. Dimensions proposed: generation of ideas and their subsequent prioritizing; 2. Proposal and prioritizing of items grouped into blocks of Knowledge and Attitudes, developed between August 2012 and January 2013. The work was carried out by initial telephone contact with panellists, and then later by the panellists belonged to the Andalusia Public Health System. The criteria for selecting the eight components of the panel were knowledge and experience in the field of the freedom of the patient in Andalusia. The Knowledge identified included: 1 A) Legal and general aspects; 2 A) A conceptual definition; 3 A) Standardised LWD documents: 4 A) Practical experience; 5 A) Procedure and registering of the LWDs. The second block included Attitudes: 1 B) Attitudes of the professional in the application of LWDs in clinical practice, and 2 B) Attitudes of the professional in «complex» ethical scenarios The 7 panellists who finally took part proposed 165 items. After applying the prioritizing criteria, scores, and scenario selection, 58 (35.2%) items were identified as suitable scenarios. The proposed questionnaire included wide parcels of concepts and contents that, once validated, will help to measure the training interventions carried out on health professionals in order to improve knowledge and attitudes on the subject of LWDs.

[Right of self-determination and the duty to treat--the conflict between the patients's right to self-determination and the physician's duty to treat in relation to living wills].

PubMed

Moe, C; Schroll, M

1994-11-21

The principle of autonomy requires competency. A competent patient is a patient who is capable of exercising his or her right to self-determination. However, in practical clinical work there is a continuum between competency and incompetency, and it is the doctor who has to decide whether the right to autonomy can be meaningfully upheld. When a patient rejects curative treatment, a conflict arises between the patient's right to autonomy and the doctor's duty to treat. While emphasizing the principle of autonomy is a guideline, the presence or absence of a living will is almost misguided. One may fear that the question of whether cure or relief is possible may altogether be neglected when a living will is in existence. The interpretation of when a living will should be used is dependent on the health staff's evaluation. There are widely divergent opinions of when a person is unavoidably dying or permanently incapable of taking care of themselves physically and mentally. If a treatment does not have a view to a cure, an improvement or a relief of symptoms it should in all circumstances be discontinued, independently of whether or not a living will is in existence.

Self-determination is a core element of human dignity. Advance directive documents include a living will, and durable power of attorney for healthcare. This article reviews current issues and ethical dilemmas with regard to advance directives. Patients, family members, and clinicians may require better education on the Hospice-Palliative Care Act in order to respect more appropriately patient end of life medical care wishes.

Live chat alternative security protocol

Indonesia is one of the largest e-commerce markets in Southeast Asia, as many as 5 million people do transactions in e-commerce, therefore more and more people use live chat service to communicate with customer service. In live chat, the customer service often asks customers’ data such as, full name, address, e-mail, transaction id, which aims to verify the purchase of the product. One of the risks that will happen is sniffing which will lead to the theft of confidential information that will cause huge losses to the customer. The anticipation that will be done is build an alternative security protocol for user interaction in live chat by using a cryptographic algorithm that is useful for protecting confidential messages. Live chat requires confidentiality and data integration with encryption and hash functions. The used algorithm are Rijndael 256 bits, RSA, and SHA256. To increase the complexity, the Rijndael algorithm will be modified in the S-box and ShiftRow sections based on the shannon principle rule, the results show that all pass the Randomness test, but the modification in Shiftrow indicates a better avalanche effect. Therefore the message will be difficult to be stolen or changed.

Will Life Be Worth Living in a World Without Work? Technological Unemployment and the Meaning of Life.

PubMed

Danaher, John

2017-02-01

Suppose we are about to enter an era of increasing technological unemployment. What implications does this have for society? Two distinct ethical/social issues would seem to arise. The first is one of distributive justice: how will the (presumed) efficiency gains from automated labour be distributed through society? The second is one of personal fulfillment and meaning: if people no longer have to work, what will they do with their lives? In this article, I set aside the first issue and focus on the second. In doing so, I make three arguments. First, I argue that there are good reasons to embrace non-work and that these reasons become more compelling in an era of technological unemployment. Second, I argue that the technological advances that make widespread technological unemployment possible could still threaten or undermine human flourishing and meaning, especially if (as is to be expected) they do not remain confined to the economic sphere. And third, I argue that this threat could be contained if we adopt an integrative approach to our relationship with technology. In advancing these arguments, I draw on three distinct literatures: (1) the literature on technological unemployment and workplace automation; (2) the antiwork critique-which I argue gives reasons to embrace technological unemployment; and (3) the philosophical debate about the conditions for meaning in life-which I argue gives reasons for concern.

Underprotection of unpredictable statistical lives compared to predictable ones

PubMed Central

Evans, Nicholas G.; Cotton-Barratt, Owen

2016-01-01

Existing ethical discussion considers the differences in care for identified versus statistical lives. However there has been little attention to the different degrees of care that are taken for different kinds of statistical lives. Here we argue that for a given number of statistical lives at stake, there will sometimes be different, and usually greater care taken to protect predictable statistical lives, in which the number of lives that will be lost can be predicted fairly accurately, than for unpredictable statistical lives, where the lives are at stake because of a low-probability event, such that most likely no one will be affected by the decision but with low probability some lives will be at stake. One reason for this difference is the statistical challenge of estimating low probabilities, and in particular the tendency of common approaches to underestimate these probabilities. Another is the existence of rational incentives to treat unpredictable risks as if the probabilities were lower than they are. Some of these factors apply outside the pure economic context, to institutions, individuals, and governments. We argue that there is no ethical reason to treat unpredictable statistical lives differently from predictable statistical lives. Moreover, lives that are unpredictable from the perspective of an individual agent may become predictable when aggregated to the level of a societal decision. Underprotection of unpredictable statistical lives is a form of market failure that may need to be corrected by altering regulation, introducing compulsory liability insurance, or other social policies.

How structure relates to function—across spatial scales, from the single molecule to the whole organism—is a central theme in biology. Bioengineers, however, wrestle with the converse question: will function follow form? That is, we struggle to approximate the architecture of living tissues experimentally, hoping that the structure we create will lead to the function we desire. A new means to explore the relationship between form and function in living tissue has arrived with three-dimensional printing, but the technology is not without limitations. PMID:24937565

For reasons of geography and geophysics, the poles of our planet, the Arctic and Antarctica, are places where climate change appears first: they are global canaries in the mine shaft. But while Antarctica (its penguins and ozone hole, for example) has been relatively well-documented in recent books, TV programs and journalism, the far North has received somewhat less attention. This project builds on and advances what has been done to date to share the people, places, and stories of the North with all Americans through multiple media, over several years. In a collaborative project between the Arctic Research Consortium of the United States (ARCUS) and PASSPORT TO KNOWLEDGE, Live from the Arctic will bring the Arctic environment to the public through a series of primetime broadcasts, live and taped programming, interactive virtual field trips, and webcasts. The five-year project will culminate during the 2007-2008 International Polar Year (IPY). Live from the Arctic will: A. Promote global understanding about the value and world -wide significance of the Arctic, B. Bring cutting-edge research to both non-formal and formal education communities, C. Provide opportunities for collaboration between arctic scientists, arctic communities, and the general public. Content will focus on the following four themes. 1.

Vehicle emissions of short-lived and long-lived climate forcers: trends and tradeoffs.

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

Live surgery is an important part of surgical education, with an increase in the number of live surgery events (LSEs) at meetings despite controversy about their real educational value, risks to patient safety, and conflicts of interest. To provide a European Association of Urology (EAU) policy on LSEs to regulate their organisation during urologic meetings. The project was carried out in phases: a systematic literature review generating key questions, surveys sent to Live Surgery Panel members, and Internet- and panel-based consensus finding using the Delphi process to agree on and formulate a policy. The EAU will endorse LSEs, provided that the EAU Code of Conduct for live surgery and all organisational requirements are followed. Outcome data must be submitted to an EAU Web-based registry and complications reported using the revised Martin criteria. Regular audits will take place to evaluate compliance as well as the educational role of live surgery. This policy represents the consensus view of an expert panel established to advise the EAU. The EAU recognises the educational role of live surgery and endorses live case demonstration at urologic meetings that are conducted within a clearly defined regulatory framework. The overriding principle is that patient safety must take priority over all other considerations in the conduct of live surgery. Controversy exists regarding the true educational value of live surgical demonstrations on patients at surgical meetings. An EAU committee of experts developed a policy on how best to conduct live surgery at urologic meetings. The key principle is to ensure safety for every patient, including a code of conduct and checklist for live surgery, specific rules for how the surgery is organised and performed, and how each patient's results are reported to the EAU.

Chance vs. necessity in living systems: a false antinomy.

PubMed

Buiatti, Marcello; Buiatti, Marco

2008-01-01

The concepts of order and randomness are crucial to understand 'living systems' structural and dynamical rules. In the history of biology, they lay behind the everlasting debate on the relative roles of chance and determinism in evolution. Jacques Monod [1970] built a theory where chance (randomness) and determinism (order) were considered as two complementary aspects of life. In the present paper, we will give an up to date version of the problem going beyond the dichotomy between chance and determinism. To this end, we will first see how the view on living systems has evolved from the mechanistic one of the 19th century to the one stemming from the most recent literature, where they emerge as complex systems continuously evolving through multiple interactions among their components and with the surrounding environment. We will then report on the ever increasing evidence of "friendly" co-existence in living beings between a number of "variability generators", fixed by evolution, and the "spontaneous order" derived from interactions between components. We will propose that the "disorder" generated is "benevolent" because it allows living systems to rapidly adapt to changes in the environment by continuously changing, while keeping their internal harmony.

Half-Lives of 101Rh and 108m Ag

NASA Astrophysics Data System (ADS)

2014-09-01

Half-lives of short-lived nuclei can easily be measured by direct counting techniques, whereas those of long-lived naturally-occurring nuclei are usually determined by specific activity measurements. However, half-lives in the range of 1 - 1,000,000 years are notoriously difficult to determine. For example, published values for the half-life of 101Rh range from 3.0 +/- 0.4 years to 10 +/- 1 years, and for 108m Ag published values range from 127 +/- 21 years to 438 +/- 9 years. In order to resolve the issues of what the half-lives of these isotopes actually are, we set up two separate long-term gamma-ray counting experiments. Gamma-ray data were collected in time bins using high-purity Ge detectors and ORTEC PC-based data acquisition systems. We counted in this manner for a period of approximately 5 years for 101Rh and 3 years for 108mAg. In this talk we will describe the details of these experiments and will present the final results for the half-lives of 101Rh and 108mAg determined from these measurements.

To describe the nutritional status of older persons living at home, to investigate factors of importance for nutritional status, and to describe possible relationships between nutritional status and health-related quality of life (HRQoL). A longitudinal study using data from older persons born between 1916 and 1925. Data were collected at three occasions separated by four-year intervals. Data collection was carried out in the participants' own homes. An experimenter administered all tests and conducted the interviews. A randomized selection from the Swedish Twin Register included 258 persons, all still living at home. Nutritional status was assessed using the Mini Nutritional Assessment (MNA), cognitive function using the Mini-Mental State Examination (MMSE) and HRQoL using the Nottingham Health Profile (NHP). Questions covering physical, psychological and social factors that may have an impact on nutritional status were also posed. Approximately 17% of participants were assessed as being at risk for malnutrition or as being malnourished. Cognitive impairment, reduced perceived health, recent hospital stay and receiving meals-on-wheels were factors associated with being at risk for malnutrition. Being at risk for malnutrition is common in older persons living at home, and many factors related to frailty increase this risk in later life. Making use of knowledge of these factors when giving care to older persons may be important in preventing nutritional problems.

Ethical Issues in Live-Donor Reimbursement Program.

Reimbursement of expenses and costs incurred by live organ donation is permitted in many countries to encourage donation and to protect the welfare of live donors. Potential ethical issues may arise with reimbursement programs and their implementation, which vary across countries. This paper discusses some ethical issues with live donor reimbursement to stimulate discussion on how to ethically enhance its implementation to improve outcomes for both donors and recipients. In addition, we will consider whether reimbursement should be supplemented with compensation for nonfinancial losses, such as pain and suffering, to encourage live donation.

Live Cell Imaging and Measurements of Molecular Dynamics

w3-2 Live cell microscopy is becoming widespread across all fields of the life sciences, as well as, many areas of the physical sciences. In order to accurately obtain live cell microscopy data, the live specimens must be properly maintained on the imaging platform. In addition, the fluorescence light path must be optimized for efficient light transmission in order to reduce the intensity of excitation light impacting the living sample. With low incident light intensities the processes under study should not be altered due to phototoxic effects from the light allowing for the long term visualization of viable living samples. Aspects for maintaining a suitable environment for the living sample, minimizing incident light and maximizing detection efficiency will be presented for various fluorescence based live cell instruments. Raster Image Correlation Spectroscopy (RICS) is a technique that uses the intensity fluctuations within laser scanning confocal images, as well as the well characterized scanning dynamics of the laser beam, to extract the dynamics, concentrations and clustering of fluorescent molecules within the cell. In addition, two color cross-correlation RICS can be used to determine protein-protein interactions in living cells without the many technical difficulties encountered in FRET based measurements. RICS is an ideal live cell technique for measuring cellular dynamics because the potentially damaging high intensity laser bursts required for photobleaching recovery measurements are not required, rather low laser powers, suitable for imaging, can be used. The RICS theory will be presented along with examples of live cell applications.

[Cancer Survivorship: the patient and medical care staff - how will society deal with cancer ?].

Honda, Mayumi

2011-07-01

Instead of being preoccupied with treatment effectiveness, rates of survival, and asking how much longer will I live?, let us think in terms of how will I live my life the way I want to live it? In recent years, a new way of thinking called Cancer Survivorship has emerged in the United States, and has been drawing attention in Japan. Cancer Survivorship is a concept developed by a cancer patient support group in the United States in 1986, focusing on the experience of living with, through, and beyond cancer. Opposing society's narrow view of cancer patients as victims handed out a death sentence, Cancer Survivorship focuses on living life to the fullest from the time of cancer diagnosis until the moment of death,and works as a movement appealing to society to allow cancer survivors the right to live as they wish. This way of thinking has spread globally, and in Italy, a movement aimed at protecting cancer survivors' freedom to do paid work has unfolded. Even in Japan, with an increase in the number of cancer patients and an improved five-year survival rate, patient support groups have been emerging with the Cancer Survivorship mentality. However, Japanese society still has not given the movement sufficient recognition, and the question now is if cancer patients, even those in the terminal stage, can seize their lives and be someone who lives in the present.

Live-cell imaging of cyanobacteria.

PubMed

Yokoo, Rayka; Hood, Rachel D; Savage, David F

2015-10-01

Cyanobacteria are a diverse bacterial phylum whose members possess a high degree of ultrastructural organization and unique gene regulatory mechanisms. Unraveling this complexity will require the use of live-cell fluorescence microscopy, but is impeded by the inherent fluorescent background associated with light-harvesting pigments and the need to feed photosynthetic cells light. Here, we outline a roadmap for overcoming these challenges. Specifically, we show that although basic cyanobacterial biology creates challenging experimental constraints, these restrictions can be mitigated by the careful choice of fluorophores and microscope instrumentation. Many of these choices are motivated by recent successful live-cell studies. We therefore also highlight how live-cell imaging has advanced our understanding of bacterial microcompartments, circadian rhythm, and the organization and segregation of the bacterial nucleoid.

Your friends know how long you will live: a 75-year study of peer-rated personality traits.

Jackson, Joshua J; Connolly, James J; Garrison, S Mason; Leveille, Madeleine M; Connolly, Seamus L

2015-03-01

Although self-rated personality traits predict mortality risk, no study has examined whether one's friends can perceive personality characteristics that predict one's mortality risk. Moreover, it is unclear whether observers' reports (compared with self-reports) provide better or unique information concerning the personal characteristics that result in longer and healthier lives. To test whether friends' reports of personality predict mortality risk, we used data from a 75-year longitudinal study (the Kelly/Connolly Longitudinal Study on Personality and Aging). In that study, 600 participants were observed beginning in 1935 through 1938, when they were in their mid-20s, and continuing through 2013. Male participants seen by their friends as more conscientious and open lived longer, whereas friend-rated emotional stability and agreeableness were protective for women. Friends' ratings were better predictors of longevity than were self-reports of personality, in part because friends' ratings could be aggregated to provide a more reliable assessment. Our findings demonstrate the utility of observers' reports in the study of health and provide insights concerning the pathways by which personality traits influence health. © The Author(s) 2015.

To evaluate the knowledge, the experience and the attitudes of the health professionals of Primary (PC) and Specialized (SC) Carein our Health Area with respect to Living Wills (LW). Descriptive, cross-sectional study, by means of a survey addressed to PC and SC doctors Ferrol (Galicia, Spain) Health Area A total of 120 (42.85%) doctors completed the questionnaire.The professionals self-assessed their level of knowledge with a mean of 3.83 (rank from 0 to 10). Only 21 professionals (17.5%) had objective knowledge of LW, that is to say, they fulfilled the following premises: they had read some pieces of LW legislation, had read an LW document and knew the elements that could figure in it. There were differences that verged on the statistical significance in the objective knowledge between PC and SC doctors (11.7% versus 23.3%, P= .093) and between professionals with under 10 years of professional experience and those with more than 10 years (6.9% versus 21.1%, P=.081). These differences reached statistical significance in some of the items that valued the objective knowledge. A few professionals (28 (23.3%)), had explained to their patients the convenience of having written an LW document, and even fewer (8 (6,7%)) had helped patients with writing one. The knowledge of health care professionals can be clearly improved. The highest deficiency was found between PC professionals and those with less experience. Nevertheless, they showed a favourable attitude towards them. Copyright © 2012 SECA. Published by Elsevier Espana. All rights reserved.

Predicting What Will Happen When You Intervene.

Cartwright, Nancy; Hardie, Jeremy

2017-01-01

This paper offers some rules of thumb that practicing social workers can use for case studies that aim to construct, albeit not fully and never entirely reliably, models designed to help predict what will happen if they intervene in specific ways to help this particular client, here and now. We call these 'ex ante case-specific causal models'. 'Ex ante' because they are for before-the-fact prediction of what the likely effects of proposed actions are. 'Case-specific' because we are not concerned with studies that provide evidence for some general conclusion but rather with using what general and local knowledge one can get to predict what will happen to a specific client in the real settings in which they live. 'Causal' because this kind of case study aims to trace out as best possible the web of causal processes that will be responsible for what happens. In this sense our case studies resemble post facto realist evaluations.

Short Lived Fission Product Yield Measurements in 235U, 238U and 239Pu

Yields of short lived fission products (FPYs) with half lives of a few minutes to an hour contain a wealth of information about the fission process. Knowledge of short lived FPYs would contribute to existing data on longer lived FPY mass and charge distributions. Of particular interest are the relative yields between the ground states and isomeric states of FPYs since these isomeric ratios can be used to determine the angular momentum of the fragments. Over the past five years, a LLNL-TUNL-LANL collaboration has made precision measurements of FPYs from quasi-monoenergetic neutron induced fission of 235U, 238U and 239Pu. These efforts focused on longer lived FPYs, using a well characterized dual fission chamber and several days of neutron beam exposure. For the first time, this established technique will be applied to measuring short lived FPYs, with half lives of minutes to less than an hour. A feasibility study will be performed using irradiation times of < 1 hour, improving the sensitivity to short lived FPYs by limiting the buildup of long lived isotopes. Results from this exploratory study will be presented, and the implications for isomeric ratio measurements will be discussed. This work was performed under the auspices of US DOE by LLNL under Contract DE-AC52-07NA27344.

If We Build It, Will They Come? Perceptions of HIV Cure-Related Research by People Living with HIV in Four U.S. Cities: A Qualitative Focus Group Study.

Global interest and investment in the search for an HIV cure has increased. Research has focused on what experts refer to as a sterilizing or eradicating cure, where HIV is eliminated from the body, and on what is often called a functional cure, where HIV remains, kept durably suppressed in the absence of antiretroviral treatment and therapy (ART). Many believe that a functional cure is likely to be found first. HIV cure studies will require active participation by people living with HIV (PLWHIV). Their desires and perceptions will be important to effectively recruit study participants and for the uptake of any future strategy that demonstrates safety and efficacy. The perspectives of PLWHIV are essential to advancing HIV cure research, and they should be taken into consideration as biomedical research advances. We conducted 10 focus groups in four U.S. cities, eliciting perspectives of PLWHIV on HIV cure and cure research. Most participants conceived of a cure as eradicating, and felt favorably toward it. In addition to the physical benefits of a potential cure, participants valued the possible de-stigmatization related to no longer living with HIV, liberation from concerns about transmitting HIV, and freedom from the burden of daily medication. Many participants did not regard a functional cure as an improvement over controlling HIV through ART, were distrustful about viral rebound potential, and noted concerns about medical complications and accompanying psychological distress. Some felt that the risks of HIV cure research were not worth taking. Many were skeptical about science's ability to eliminate HIV from the body.

How long does a space or an object have to last? If in the past an object or a building manufacturing was designed to last as much as possible, nowadays it is designed to have a life related to the time in which it will be used. Flexibility is what characterizes a space, it’s the ability to be variable and adaptable to changes in the lives of users or in relation to the use which these will make over time. The evolution of the labour market, the difficulty of inserting within it and the need to push more and more frequent move today in the trial of living space models increasingly flexible: people, especially young people, are forced to move on territory outlining a new condition to which the flexible nomadic dwellings offer an adequate response, ensuring high functional performance in confined spaces.

Live Ultra-High Definition from the International Space Station

NASA Technical Reports Server (NTRS)

Grubbs, Rodney; George, Sandy

2017-01-01

The first ever live downlink of Ultra-High Definition (UHD) video from the International Space Station (ISS) was the highlight of a 'Super Session' at the National Association of Broadcasters (NAB) in April 2017. The Ultra-High Definition video downlink from the ISS all the way to the Las Vegas Convention Center required considerable planning, pushed the limits of conventional video distribution from a space-craft, and was the first use of High Efficiency Video Coding (HEVC) from a space-craft. The live event at NAB will serve as a pathfinder for more routine downlinks of UHD as well as use of HEVC for conventional HD downlinks to save bandwidth. HEVC may also enable live Virtual Reality video downlinks from the ISS. This paper will describe the overall work flow and routing of the UHD video, how audio was synchronized even though the video and audio were received many seconds apart from each other, and how the demonstration paves the way for not only more efficient video distribution from the ISS, but also serves as a pathfinder for more complex video distribution from deep space. The paper will also describe how a 'live' event was staged when the UHD coming from the ISS had a latency of 10+ seconds. Finally, the paper will discuss how NASA is leveraging commercial technologies for use on-orbit vs. creating technology as was required during the Apollo Moon Program and early space age.

It would be hard to argue that live-cell imaging has not changed our view of biology. The past 10 years have seen an explosion of interest in imaging cellular processes, down to the molecular level. There are now many advanced techniques being applied to live cell imaging. However, cellular health is often under appreciated. For many researchers, if the cell at the end of the experiment has not gone into apoptosis or is blebbed beyond recognition, than all is well. This is simply incorrect. There are many factors that need to be considered when performing live-cell imaging in order to maintain cellular health such as: imaging modality, media, temperature, humidity, PH, osmolality, and photon dose. The wavelength of illuminating light, and the total photon dose that the cells are exposed to, comprise two of the most important and controllable parameters of live-cell imaging. The lowest photon dose that achieves a measureable metric for the experimental question should be used, not the dose that produces cover photo quality images. This is paramount to ensure that the cellular processes being investigated are in their in vitro state and not shifted to an alternate pathway due to environmental stress. The timing of the mitosis is an ideal canary in the gold mine, in that any stress induced from the imaging will result in the increased length of mitosis, thus providing a control model for the current imagining conditions.

The purpose of this study was to establish the relationship between the will of bedridden elderly people to be self-reliant and their life prognosis, and to clarify the factors related to the will to be self-reliant of such persons.The cohort consisted of 274 bedridden elderly persons aged 65 years and over who lived at home and were observed continually over ten years. Data were obtained from observation records done by four public health nurses who visited the subjects at least once a year and assessed their state of health. The variables studied were demographic variables, activities of daily living, the cause of being bedridden, the strength of the will to be self-reliant and the date of having become bedridden. Cox's proportional hazard model, the Kaplan-Meier method and discriminant analysis were used for statistical analysis.Of the 274 subjects, 107 subjects (39.1%) were male and 167 (60.9%) female, with a mean age of 82 years. The subjects who lived with their families accounted for 96.7%. The mortality hazard ratio for subjects with a weak will to be self-reliant to those with a strong will was 1.64, which was statistically significant. Discriminant analysis demonstrated that the will to be self-reliant showed a significant relationship with age, level of activities of daily living and refraining from expressing one's own feelings in consideration of the family's feelings.Bedridden elderly persons with a strong will to be self-reliant had a significandy better life prognosis than those with a weak one. A strong will to be self-reliant among the elderly is related to age, level of activities of daily living, and refraining from expressing one's own feelings in consideration of the family's feelings.This study clearly points out the need for home care service personnel to work in cooperation with families to emphasize encouragement to build the will to be self-reliant for the elderly in Japan.

The goal is to encourage public participation in policy formulation. The book emphasizes that escapism will not improve security; that idealistic plans to eliminate nuclear weapons are a form of escapism. Learning to live with nuclear weapons, they suggest, requires an understanding of the current nuclear predicament and the implications of alternative weapons and policy choices. After reviewing these matters, they emphasize that informed persons will continue to disagree, but that knowledge will improve understanding andmore » appreciation of their differences and improve the quality of policy debates. 54 references, 5 figures, 2 tables.

1989-12-01

In 1986, we adapted the Tandem Scanning Reflected Light Microscope of Petran and Hadraysky to permit non-invasive, confocal imaging of the living eye in real-time. We were first to obtain stable, confocal optical sections in vivo, from human and animal eyes. Using confocal imaging systems we have now studied living, normal volunteers, rabbits, cats and primates sequentially, non-invasively, and in real-time. The continued development of real-time confocal imaging systems will unlock the door to a new field of cell biology involving for the first time the study of dynamic cellular processes in living organ systems. Towards this end we have concentrated our initial studies on three areas (1) evaluation of confocal microscope systems for real-time image acquisition, (2) studies of the living normal cornea (epithelium, stroma, endothelium) in human and other species; and (3) sequential wound-healing responses in the cornea in single animals to lamellar-keratectomy injury (cellular migration, inflammation, scarring). We believe that this instrument represents an important, new paradigm for research in cell biology and pathology and that it will fundamentally alter all experimental and clinical approaches in future years.

Downey, A M

1983-01-01

Living, loving and losing - we live, we love and we lose - this is an integral part of life's unending circle. Throughout the lifecycle, we are confronted continually with experiences of loss and separation. The loss of a loved one through separation, divorce, or death is one of the most difficult experiences to be dealt with in a lifetime. How do we cope with the "crisis of loss" in our lives? If education is supposed to prepare one for life, then Death Education is crucial in assisting individuals to cope with "myriad loss issues." This paper will explore the implications of loss for health and well-being, and briefly review some of the research findings regarding the negative impact of grief and bereavement upon health. The stages of the grief process will be cited, mentioning some of the barriers to grief resolution. Most importantly, the positive aspects of loss upon life and health will be elaborated.

Bubbles in supersaturated tissues and blood occur in beaked whales stranded near sonar exercises, and post-mortem in dolphins bycaught at depth and then hauled to the surface. To evaluate live dolphins for bubbles, liver, kidneys, eyes and blubber-muscle interface of live-stranded and capture-release dolphins were scanned with B-mode ultrasound. Gas was identified in kidneys of 21 of 22 live-stranded dolphins and in the hepatic portal vasculature of 2 of 22. Nine then died or were euthanized and bubble presence corroborated by computer tomography and necropsy, 13 were released of which all but two did not re-strand. Bubbles were not detected in 20 live wild dolphins examined during health assessments in shallow water. Off-gassing of supersaturated blood and tissues was the most probable origin for the gas bubbles. In contrast to marine mammals repeatedly diving in the wild, stranded animals are unable to recompress by diving, and thus may retain bubbles. Since the majority of beached dolphins released did not re-strand it also suggests that minor bubble formation is tolerated and will not lead to clinically significant decompression sickness.

High rates of HIV and poverty place women in a precarious economic situation in Lusaka, Zambia. Mortality from HIV infection is high, leaving many households single headed and creating almost a half a million orphans. One of the most prevalent forms of gender violence that creates poverty in women is when the male's family claims the property of the deceased from the widow and the children. The Zambia-Emory HIV Research Project collected 184 wills from individuals in monogamous unions where one or both of the individuals were HIV-positive. Despite the fact that many wills specifically stated that their extended family was not allowed to tamper with their possessions in the event of death, property grabbing proved to be a prevalent and difficult issue in Lusaka. In order to improve the lives of widowed women in Lusaka, the government and other civic and non-governmental organisations must inform women of their rights to own and protect their land and other assets in the event of their husbands' death, an issue of increasing importance in the area of HIV/AIDS.

The delicate balance in genetically engineering live vaccines

PubMed Central

Galen, James E.; Curtiss, Roy

2014-01-01

Contemporary vaccine development relies less on empirical methods of vaccine construction, and now employs a powerful array of precise engineering strategies to construct immunogenic live vaccines. In this review, we will survey various engineering techniques used to create attenuated vaccines, with an emphasis on recent advances and insights. We will further explore the adaptation of attenuated strains to create multivalent vaccine platforms for immunization against multiple unrelated pathogens. These carrier vaccines are engineered to deliver sufficient levels of protective antigens to appropriate lymphoid inductive sites to elicit both carrier-specific and foreign antigen-specific immunity. Although many of these technologies were originally developed for use in Salmonella vaccines, application of the essential logic of these approaches will be extended to development of other enteric vaccines where possible. A central theme driving our discussion will stress that the ultimate success of an engineered vaccine rests on achieving the proper balance between attenuation and immunogenicity. Achieving this balance will avoid over-activation of inflammatory responses, which results in unacceptable reactogenicity, but will retain sufficient metabolic fitness to enable the live vaccine to reach deep tissue inductive sites and trigger protective immunity. The breadth of examples presented herein will clearly demonstrate that genetic engineering offers the potential for rapidly propelling vaccine development forward into novel applications and therapies which will significantly expand the role of vaccines in public health.

Managing patients with inflammatory bowel disease requires multidisciplinary coordination. Technological advances have enhanced access to care for patients and improved physician interactions. The primary aim of our project was to convene diverse institutions and specialties through a multisite virtual conferencing platform to discuss complex patient management. The case conference is designed to include multiple institutions to exchange ideas, review evidence-based data, and provide input on the management of patients with Crohn's disease and ulcerative colitis. Technology is supplied and coordinated by an information technology specialist and Chorus Call, Inc., an international teleconferencing service provider. The Inflammatory Bowel Disease Live Interinstitutional Interdisciplinary Videoconference Education (IBD LIVE) initiative is accredited by the University of Pittsburgh Medical Center (UPMC) Center for Continuing Education in the Health Sciences for 1 AMA PRA Category 1 Credit per weekly session. IBD LIVE began in 2009 comprising only adult gastroenterology and pediatric gastroenterology from UPMC Presbyterian and Children's Hospitals. Participation steadily increased from 5 sites in 2010 to 11 sites in 2014. Maximum attendance for a single conference was 73 participants with a median of 48. The Continuing Medical Education scores (1 = worst to 5 = best) have a high median overall score (4.6, range 3.2-5.0) with positive responses with regard to the degree to which the conference changed practice. IBD LIVE has been successful and continues to grow. Implementation of the Crohn's and Colitis Foundation of America Virtual Preceptor Program using the IBD LIVE platform will provide expanded national physician access to this professional education activity.

Engendering independence while living with purpose: women's lives after leaving abusive intimate partners.

McDonald, Penelope W; Dickerson, Suzanne

2013-12-01

The purpose of this study was to determine the common meanings a history of violence has for women out of abusive and violent relationships with an intimate male partner for 5 or more years. To describe the common meanings and shared practices of women who left violent and abusive heterosexual intimate relationships 5 or more years ago, the challenges they face in their current lives, and the resources they use to meet those challenges. An additional aim is to elucidate practical advice they have for others who want to be supportive of the efforts of women recovering from intimate partner violence. An interpretive phenomenological approach using Heideggerian hermeneutics was utilized. Approval of the University Social Sciences Institutional Review Board was obtained. Participants were recruited by means of fliers distributed through a domestic violence listserv and through postings in health clinics in western New York. Interviews were recorded and transcribed. A hermeneutic team approach was used for analysis and interpretation of texts. Twenty-one women of various ages, ethnicities, and backgrounds, who self-identified as being out of abusive relationships for 5 or more years, were interviewed. Six themes were identified: developing and maintaining self reliance; negotiating relationships; creating a safe and supportive environment; challenging societal roles and expectations; nurturing the self; and protecting the children. Engendering independence while living with purpose was the constitutive pattern that unified the themes. Women can successfully establish productive, meaningful lives after violence and will fiercely protect and maintain their independence as they negotiate relationships and developmental challenges throughout their lives. A need for control of their lives and difficulty trusting others remain a lasting legacy of living with a history of violence. This is the first study that examines women's lives 5 or more years after leaving violent and

[Distant mental influence on living organisms].

PubMed

Bonilla, Ernesto

2013-12-01

This article reviews studies of distant mental influence on living organisms, including mental suggestions of sleeping and awakening, mental influence at long distances, mental interactions with remote biological systems, mental effects on physiological activity and the sense of being stared at. Significant effects of distant mental influence have been shown in several randomized controlled trials in humans, animals, plants, bacteria and cells in the laboratory. Although distant mental influence on living organisms appears to contradict our ordinary sense of reality and the laws defined by conventional science, several hypotheses have been proposed to explain the observed effects; they include skeptical, signal transfer, field, multidimensional space/time and quantum mechanics hypotheses. In conclusion, as the progress of physics continues to expand our comprehension of reality, a rational explanation for distant mind-matter interaction will emerge and, as history has shown repeatedly, the supernatural events will evolve into paranormal and then, into normal ones, as the scientific frontiers expand.

Finished with Menthol: An Evidence-Based Policy Option That Will Save Lives.

PubMed

Lester, Joelle M; Gagosian, Stacey Younger

2017-03-01

Smoking remains the leading cause of preventable disease and death in the United States, killing approximately 480,000 people each year. This crushing health burden falls disproportionately, and recent CDC data shows that large disparities in adult cigarette smoking remain. One factor in these disparities is the use of flavors. Menthol cigarettes and other flavored tobacco products are used at higher rates by vulnerable populations including youth and young adults, African Americans, women, Hispanics and Asian Americans. This is no accident; the tobacco industry has long targeted these same groups. Given FDA's failure to act to ban flavored tobacco products, states and municipalities are considering taking matters into their own hands to protect their communities from these dangerous products. The authors will explore state and local authority to restrict the sales of these products and review the evidence base indicating that removing flavored tobacco products - and menthol combustible products in particular - from the market would significantly reduce the toll of illness and death caused by these products.

Should living kidney donor candidates with impaired fasting glucose donate?

PubMed

Vigneault, Christine Buchek; Asch, William Stuart; Dahl, Neera Kanhouwa; Bia, Margaret Johnson

2011-08-01

As the kidney transplant waiting list grows, the willingness of transplant centers to accept complex donors increases. Guidelines for the evaluation of living kidney donors exist but do not provide clear guidance when evaluating the complex donor. Although few transplant centers will approve donor candidates with impaired glucose tolerance and most, if not all, will deny candidates with diabetes, many will approve candidates with impaired fasting glucose (IFG). Furthermore, the demographic of living donors has changed in the past 10 years to increasingly include more nonwhite and Hispanic individuals who are at greater risk for future diabetes and hypertension. IFG may be more of a concern in potential donors whose nonwhite and Hispanic ethnicity already places them at greater risk. We review the definition of diabetes, diabetes prediction tools, and transplant guidelines for donor screening and exclusion as it pertains to impaired glucose metabolism, and additional ethnic and nonethnic factors to consider. We offer an algorithm to aid in evaluation of potential living donors with IFG in which ethnicity, age, and features of the metabolic syndrome play a role in the decision making.

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

Living Independently: Exploring the Experiences of Visually Impaired People Living in Age-Related and Lifetime Housing Through Qualitative Synthesis.

2017-01-01

The aim of this study is to gain a deeper understanding of the experiences of visually impaired older people living independently at home. As populations are aging globally, there is now an increase in the prevalence of visual impairment. That means for ongoing and future aging-in-place strategies that seek to enable older people to remain independent for longer, more attention needs to be given to the needs of those with visual impairment. As people develop visual impairment, they use adaptive strategies including modifying long-term homes or relocating to more suitable accommodation. In the United Kingdom, aging-in-place strategies include employing statutory lifetime home standards (LTHS) in the home or relocating to sheltered housing to live independently with support available if required. To get a better understanding of the needs of the visually impaired in the home, 12 interviews with six visually impaired occupants of LTHS homes and six from sheltered accommodation were analyzed separately using interpretative phenomenological analysis. Secondly, qualitative synthesis was used to further analyze themes generated from both samples before interview results were conceptualized in two superordinate concepts, namely, "negotiating priorities" and "understanding visual impairment." Participants from both groups had similar needs and were willing to compromise by living with some negative features. Those who coped well with moving utilized various resources. These findings will shed more understanding on providing good quality housing for those with visual impairment wanting to live either independently or within healthcare home environments.

Living my narrative: storying dishonesty and deception in mental health nursing.

PubMed

Grant, Alec J

2016-07-01

This article proceeds from MacIntyre's moral philosophical perspective of individual human lives constituting unified narratives, in the context of co-evolving framing and guiding master narratives. This perspective accords specific episodes in people's lives the status of significant component parts of their developing, storied and enacted individual histories. From this philosophical base, autoethnographic principles will be employed in providing accounts from my own professional life narrative strand as a mental health nurse educator that speak to the issue of institutionalized dishonesty and deception in mental health nursing education and practice. On the basis of my pre-existing experience of publishing in nursing journals and scholarly identity, my argument will proceed from contesting the idea of an imagined stable foundational professional ethos underpinning mental health nursing practice, against which to judge professional dishonesty and deception. Using illustrative, relatively recent short stories, drawn from my lived-experience base as a mental health nurse educator, I will argue throughout at implicit and explicit levels that dishonesty and deception are always an inevitable part of the lives of mental health nurses and their educators. This is because of a constant gap between the nursing rhetoric and ideology that both groups espouse and how they actually behave on a day-to-day, mundane level, in and out of work and classroom practice. This gap shows up the public front of what mental health nursing is supposed to be about as dishonest and deceitful window dressing. I will assert that the many first-person, lived-experience accounts in mental health nursing teaching and publication are important educational resources in reducing this gap at professional practice, academic, and informal levels. Such storied accounts may also be useful in moving nurses and their educators towards more morally and ethically sensitive and reflexively attuned positions

Is hepatitis C virus elimination possible among people living with HIV and what will it take to achieve it?

The World Health Organization targets for hepatitis C virus (HCV) elimination include a 90% reduction in new infections by 2030. Our objective is to review the modelling evidence and cost data surrounding feasibility of HCV elimination among people living with HIV (PLWH), and identify likely components for elimination. We also discuss the real-world experience of HCV direct acting antiviral (DAA) scale-up and elimination efforts in the Netherlands. We review modelling evidence of what intervention scale-up is required to achieve WHO HCV elimination targets among HIV-infected (HIV+) people who inject drugs (PWID) and men who have sex with men (MSM), review cost-effectiveness of HCV therapy among PLWH and discuss economic implications of elimination. We additionally use the real-world experience of DAA scale-up in the Netherlands to illustrate the promise and potential challenges of HCV elimination strategies in MSM. Finally, we summarize key components of the HCV elimination response among PWLH. Modelling indicates HCV elimination among HIV+ MSM and PWID is potentially achievable but requires combination treatment and either harm reduction or behavioural risk reductions. Preliminary modelling indicates elimination among HIV+ PWID will require elimination efforts among PWID more broadly. Treatment for PLWH and high-risk populations (PWID and MSM) is cost-effective in high-income countries, but costs of DAAs remain a barrier to scale-up worldwide despite the potential low production price ($50 per 12 week course). In the Netherlands, universal DAA availability led to rapid uptake among HIV+ MSM in 2015/16, and a 50% reduction in acute HCV incidence among HIV+ MSM from 2014 to 2016 was observed. In addition to HCV treatment, elimination among PLWH globally also likely requires regular HCV testing, development of low-cost accurate HCV diagnostics, reduced costs of DAA therapy, broad treatment access without restrictions, close monitoring for HCV reinfection and

Set-Theoretic Analysis of Ethical Systems for Off-Planet Future Engagement with Living Organisms

2016-10-01

Living organisms are a conundrum. Their origin and provenance are open questions. An operational definition for their detection has been settled upon for practical reasons, i.e. in order to plan mission goals. The spirit of such undertakings is typically noble, and yet the question arises clearly related to how humanity will engage with other living organisms. Prudence demands a pre-contact appraisal of ethical requirements towards other living organisms. To answer this question, an anology with the number line in mathematics (integers versus the set of real numbers) will be presented to explore the structure of finite versus open-ended hierarchies. In this, the architecture of set theory will be used as a basis to describe the validity of systems hierarchies in general. Note that how numbers populate sets follow distinct rules when the elements of the sets or the sets themselves are unbounded. Principles of axiomatic versus observed conclusions will be emphasized. Results from mathematics will be used to inform analysis and dilemmas in ethical systems.

Enhanced neurorehabilitation techniques in the DVBIC Assisted Living Pilot Project.

2010-01-01

Traumatic Brain Injury has been labeled the "silent epidemic" in our current wars. Both CBO and the RAND reports predict that the costs of these injuries will be both extensive and enduring. The projected costs are based not only upon the loss contribution of these warriors to our economy, but also the long-term medical and assistive care that will be needed to support these veterans for decades to come. Thus, the primary goal of the Assisted Living Pilot Project (ALPP) at the Defense and Veterans Brain Injury Center - Johnstown (DVBIC-J) is to promote the ability of the injured warrior to move from assisted living to living independently and to be self-supporting by providing a continuum of care. To accomplish this goal the DVBIC-J ALPP is providing full set of traditional services (physical, occupational, speech, psychological/cognitive, social/familial, vocational, and spiritual), along with "cutting-edge" rehabilitative treatment technologies. These cutting-edge therapies include transdisciplinary clinical consultations, interactive patient and family counseling, and telemedicine-teleconferencing for clinical evaluations and family/significant other care participation. These services will be available to those who require assisted living through their progression to community re-entry. The ALPP also serves as a vehicle for clinical trials to investigate the effects of an enriched environment (e.g., recreational therapies, massage, multisensory stimulation, etc.) on neurorehabilitation therapy, rural telemedicine for servicemembers with traumatic brain injury, and long-term outcome measures of those who have received neurorehabilitation services at the DVBIC-J site. DVBIC-J is also developing collaborative projects with universities and private industry to create an incubator for new rehabilitation technologies. The technologies that DVBIC-J will be focusing on will include assistive technologies (to assist cognitive, physical, and communicative impairments

By 2050, the number of Brazilians living in urban areas will be over 200 million and 29% of the population will be elderly. The long-lived elderly are 80 or more years old and the young elderly are between 60 and 79 years of age. The scope of this article was to verify the difference in perception between the young elderly and the long-lived elderly from Rio Grande do Sul (RS) about the urban environment they live in. This is a population-based, observational, descriptive, retrospective study with a quantitative analysis paradigm. Data was analyzed from Elderly Profile research in RS conducted by the Geriatric and Gerontological Institute of PUCRS in partnership with the RS School of Public Health. The sample consisted of 6913 questionnaires answered by the elderly from 59 cities. Data analysis was performed for each age group and independent variables were processed using the Chi-square test, with p under 0.05. Results showed that the perception of difficulties such as a lack of park benches and safety strips, short traffic light times for pedestrians, high steps and bad-smelling public toilets was greater among the young elderly. The long-lived elderly noticed these facts less, though they admitted that they frequent community environments less often.

A cellulosic responsive "living" membrane.

Bacterial cellulose has been demonstrated to be a remarkably versatile biomaterial and widely used in biomedical applications due to its unique physical properties. Here we reported for the first time a "living membrane" system based on recombinant Escherichia coli bacterial strains entrapped in cellulosic membranes produced by Gluconacetobacter xylinus. Biologically driven detection and identification of a range of target molecules presents unique challenges, and requires that detection methods are developed to be rapid, specific and sensitive. The compatibility of G. xylinus and recombinant E. coli strains was first investigated for co-cultivation, and the relationship between the number of entrapped E. coli and the level of inducible signal achieved was further explored by fluorescent signal observation in confocal microscopy. Finally to amplify the response to inducers for maximum fluorescent signal, a positive-feedback genetic amplifier was designed within recombinant E. coli strain entrapped in the living cellulosic membrane system, allowing for the detection mechanism to be extremely sensitive and resulting in a significant fluorescent signal from a single receptor binding event. The living membrane system proposed here will create devices of greater complexity in function for applications in biological and chemical detection. Copyright © 2013. Published by Elsevier Ltd.

As the gap between supply and demand for donor organs is increasing, we sought to clarify the knowledge and attitudes regarding living-organ donation among Chinese medical students and analyze their incentives and influencing factors. Data were collected from Chinese medical students using a standardized questionnaire. Of 320 surveyed participants, 261 participants (81.6%) said they would consider donating their live kidney organ, and 262 participants (81.9%) were willing to donate posthumously. Although 177 participants (55.7%) confirmed current regulations on posthumous organ donation, only 85 participants (26.7%) could correctly identify the regulations on live organ donation in China. Gender differences were not significantly associated with willingness to donate a kidney, whereas religion and socioeconomic status of the respondents were significantly associated with willingness to donate a live or posthumous kidney. Among well-informed, young, healthy, and economically well-off Chinese male and female medical students, most were willing to be live kidney donors. Religion and socioeconomic status may affect the decision-making process for organ disposition.

Changing Course: The Studio Misi-Ziibi Team_ New Misi-Ziibi Living Delta

NASA Astrophysics Data System (ADS)

Hoal, J.

2016-02-01

Acknowledging that the Mississippi River Delta will continue to evolve over the next 100 years, the new MISI-ZIIBI LIVING DELTA for the 22nd century - a healthy, productive and resilient delta - relies on a synergistic and leveraged combination of delta building, the working delta, and delta living. This new Delta will be more sustainable and smaller in area, but have faster vertical accretion rates than earlier deltas, which keeps pace with current and future rates of global sea-level rise. The vision for the new Delta will be achieved through ECO 3D [dredge + dump, dredge-siphon, divert] - in which the bounded Mississippi River will be fragmented into a network of constructed distributaries, using sediment diversions, in order to feed the wetlands with the necessary sediment for delta building. Although the diversions will be constructed and managed, the delta formation in the receiving basins is self-organizing and naturally formed. In addition, we propose to shorten the Mississippi River and construct a new navigation entry point further upstream with a new distributary node near West Point à la Hache. The realigned and shortened river provides more efficient methods to use the sediment loads and increase safety and navigation reliability, and lower flood levels along the Mississippi River in this area. Ensuring that the navigation and marine economy continues to expand the river will be dredged to 50ft deep, the existing ports and Port Fourchon expanded, existing navigable inland water bodies maintained, and a new port constructed in the new Bird's Foot. We propose retreat from the southern rim of the existing Delta in order to assure long-term sustainability of the regions with the highest population density and economic productivity. The concept of DELTA LIVING is about embracing the ideology and cultural aspect of communities by enabling a means to continue to live with the Delta in new ways, and accommodating a regional growth strategy of safe, strong

Big data, smart homes and ambient assisted living.

To discuss how current research in the area of smart homes and ambient assisted living will be influenced by the use of big data. A scoping review of literature published in scientific journals and conference proceedings was performed, focusing on smart homes, ambient assisted living and big data over the years 2011-2014. The health and social care market has lagged behind other markets when it comes to the introduction of innovative IT solutions and the market faces a number of challenges as the use of big data will increase.

Summary Objectives To discuss how current research in the area of smart homes and ambient assisted living will be influenced by the use of big data. Methods A scoping review of literature published in scientific journals and conference proceedings was performed, focusing on smart homes, ambient assisted living and big data over the years 2011-2014. Results The health and social care market has lagged behind other markets when it comes to the introduction of innovative IT solutions and the market faces a number of challenges as the use of big data will increase. First, there is a need for a sustainable and trustful information chain where the needed information can be transferred from all producers to all consumers in a structured way. Second, there is a need for big data strategies and policies to manage the new situation where information is handled and transferred independently of the place of the expertise. Finally, there is a possibility to develop new and innovative business models for a market that supports cloud computing, social media, crowdsourcing etc. Conclusions The interdisciplinary area of big data, smart homes and ambient assisted living is no longer only of interest for IT developers, it is also of interest for decision makers as customers make more informed choices among today’s services. In the future it will be of importance to make information usable for managers and improve decision making, tailor smart home services based on big data, develop new business models, increase competition and identify policies to ensure privacy, security and liability.

Should health care professionals encourage living kidney donation?

PubMed

Hilhorst, Medard T; Kranenburg, Leonieke W; Busschbach, Jan J V

2007-03-01

Living kidney donation provides a promising opportunity in situations where the scarcity of cadaveric kidneys is widely acknowledged. While many patients and their relatives are willing to accept its benefits, others are concerned about living kidney programs; they appear to feel pressured into accepting living kidney transplantations as the only proper option for them. As we studied the attitudes and views of patients and their relatives, we considered just how actively health care professionals should encourage living donation. We argue that active interference in peoples' personal lives is justified - if not obligatory. First, we address the ambiguous ideals of non-directivity and value neutrality in counselling. We describe the main pitfalls implied in these concepts, and conclude that these concepts cannot account for the complex reality of living donation and transplantation. We depict what is required instead as truthful information and context-relative counselling. We then consider professional interference into personal belief systems. We argue that individual convictions are not necessarily strong, stable, or deep. They may be flawed in many ways. In order to justify interference in peoples' personal lives, it is crucial to understand the structure of these convictions. Evidence suggests that both patients and their relatives have attitudes towards living kidney donation that are often open to change and, accordingly, can be influenced. We show how ethical theories can account for this reality and can help us to discern between justified and unjustified interference. We refer to Stephen Toulmin's model of the structure of logical argument, the Rawlsian model of reflective equilibrium, and Thomas Nagel's representation of the particularistic position.

A sample of Malaysians in the Klang Valley indicating their decision on becoming unrelated living kidney donors was surveyed regarding huge amounts of financial incentives to be rewarded to them. From the 1310 respondents, 72.1% said "no" on becoming a living donor. The reason "I don't think humans can live with only one kidney" scored the highest (35.6%), and from the 27.9% of the respondents who are willing to donate their organ with the right financial incentive, most of the respondents picked the reasons "I want to do something noble in life" (50%), and monetary reason scored the lowest (6.2%), indicating that financial incentive is not a major reason guiding individuals' decision on becoming living donors. We suggest that the government should put priority at targeting public education to raise the understanding on the risk, safety and the quality of life of donation and transplantation, and improving the public trust on the donation and the surgical methods to carry out transplantation. © 2014 John Wiley & Sons A/S.

Living into the imagined body: how the diagnostic image confronts the lived body.

PubMed

Stahl, Devan

2013-06-01

In this paper I will show how the medical image, presented to the patient by the physician, participates in medicine's cold culture of abstraction, objectification and mandated normativity. I begin by giving a brief account of the use of anatomical imaging since the Renaissance to show how images have historically functioned in contrast to how they are currently used in medical practice. Next, I examine how contemporary medical imaging techniques participate in a kind of knowledge production that objectifies the human body. Finally, I elucidate how physicians ought to place the medical image within the context of the lived body so as to create a healing relationship with the patient. In all this I hope to show that the medical image, far from a piece of objective data, testifies to the interplay of particular beliefs, practices and doctrines contemporary medicine holds dear. To best treat her patient, the physician must appreciate the influence of these images and appropriately place them within the context of the patient's lived experience.

Heart failure and frailty are clinical syndromes that present with overlapping phenotypic characteristics. Importantly, their co-presence is associated with increased mortality and morbidity. While mechanical and electrical device therapies for heart failure are vital for select patients with advanced stage disease, the majority of patients and especially those with undiagnosed heart failure would benefit from early disease detection and prompt initiation of guideline-directed medical therapies. In this article, we review the problematic interactions between heart failure and frailty, introduce a focused cardiac screening program for community-living elderly initiated by a mobile communication device app leading to the Undiagnosed heart Failure in frail Older individuals (UFO) study, and discuss how the knowledge of pre-frailty and frailty status could be exploited for the detection of previously undiagnosed heart failure or advanced cardiac disease. The widespread use of mobile devices coupled with increasing availability of novel, effective medical and minimally invasive therapies have incentivized new approaches to heart failure case finding and disease management.

2015-01-01

Right lobe living donor liver transplantation (LDLT) is the predominant form of adult-to-adult LDLT. Accordingly, cosmetic and functional demand by young donors is increasing. We developed the world first total laparoscopic donor right hepatectomy (LDRH) in adult living donors. Total LDRH was performed in two young donors without vascular clamping. Modified extended right graft (right liver including all the middle hepatic vein branches) was retrieved from suprapubic transverse incision. After full mobilization of right liver, hilar dissection was done. First, right portal vein was isolated under retracting common bile duct laterally. Right hepatic artery was cautiously dissected and isolated without injuring. An exact transection line was drawn during transient clamping of the hepatic artery and portal vein on the right side of the liver using bulldog clamp. Dissection was meticulously performed along the right side of the middle hepatic vein until the origin of middle hepatic vein until exposure of the hilar plate. Anterior section vein branches (V5 and V8) were finely dissected and were reconstructed using an artificial vascular graft. A modified extended right graft with preservation of the middle hepatic vein branches was extracted through the suprapubic incision. There was no complication in both donors and recipients. Postoperative hospital stay of donors was 10 and 8 days, respectively. After follow-up of more than 1 year, all donors and recipients live well with normal liver function. Total LDRH was feasible in selected adult donors. If this procedure will be more standardized, then total LDRH will be new option for adult LDLT, which meets demand by donors and diminish guilty feeling by recipients.

NASA's plan to build and launch a fleet of long-lived space observatories that include the Hubble Space Telescope (HST), the Gamma Ray Observatory (GRO), the Advanced X Ray Astrophysics Observatory (AXAF), and the Space Infrared Telescope Facility (SIRTF) are discussed. These facilities are expected to have a profound impact on the sciences of astronomy and astrophysics. The long-lived observatories will provide new insights about astronomical and astrophysical problems that range from the presence of planets orbiting nearby stars to the large-scale distribution and evolution of matter in the universe. An important concern to NASA and the scientific community is the operation and maintenance cost of the four observatories described above. The HST cost about $1.3 billion (1984 dollars) to build and is estimated to require $160 million (1986 dollars) a year to operate and maintain. If HST is operated for 20 years, the accumulated costs will be considerably more than those required for its construction. Therefore, it is essential to plan carefully for observatory operations and maintenance before a long-lived facility is constructed. The primary goal of this report is to help NASA develop guidelines for the operations and management of these future observatories so as to achieve the best possible scientific results for the resources available. Eight recommendations are given.

MEART: The Semi-Living Artist

Here, we and others describe an unusual neurorobotic project, a merging of art and science called MEART, the semi-living artist. We built a pneumatically actuated robotic arm to create drawings, as controlled by a living network of neurons from rat cortex grown on a multi-electrode array (MEA). Such embodied cultured networks formed a real-time closed-loop system which could now behave and receive electrical stimulation as feedback on its behavior. We used MEART and simulated embodiments, or animats, to study the network mechanisms that produce adaptive, goal-directed behavior. This approach to neural interfacing will help instruct the design of other hybrid neural-robotic systems we call hybrots. The interfacing technologies and algorithms developed have potential applications in responsive deep brain stimulation systems and for motor prosthetics using sensory components. In a broader context, MEART educates the public about neuroscience, neural interfaces, and robotics. It has paved the way for critical discussions on the future of bio-art and of biotechnology.

Live pertussis vaccines: will they protect against carriage and spread of pertussis?

PubMed

Locht, C

2016-12-01

Pertussis is a severe respiratory disease that can be fatal in young infants. Its main aetiological agent is the Gram-negative micro-organism Bordetella pertussis. Vaccines against the disease have been in use since the 1950s, and global vaccination coverage has now reached more than 85%. Nevertheless, the disease has not been controlled in any country, and has even made a spectacular come-back in the industrialized world, where the first-generation whole-cell vaccines have been replaced by the more recent, less reactogenic, acellular vaccines. Several hypotheses have been proposed to explain these observations, including the fast waning of acellular vaccine-induced protection. However, recent mathematical modelling studies have indicated that asymptomatic transmission of B. pertussis may be the main reason for the current resurgence of pertussis. Recent studies in non-human primates have shown that neither whole-cell, nor acellular vaccines prevent infection and transmission of B. pertussis, in contrast to prior exposure. New vaccines that can be applied nasally to mimic natural infection without causing disease may therefore be useful for long-term control of pertussis. Several vaccine candidates have been proposed, the most advanced of which is the genetically attenuated B. pertussis strain BPZE1. This vaccine candidate has successfully completed a first-in-man phase I trial and was shown to be safe in young male volunteers, able to transiently colonize the nasopharynx and to induce antibody responses to B. pertussis antigens in all colonized individuals. Whether BPZE1 will indeed be useful to ultimately control pertussis obviously needs to be assessed by carefully conducted human efficacy trials.

With passage of the HIV Organ Policy Equity (HOPE) Act, people living with HIV (PLWH) can donate organs to PLWH awaiting transplant. Understanding knowledge and attitudes regarding organ donation among PLWH in the US is critical to implementing the HOPE Act. PLWH were surveyed regarding their knowledge, attitudes, and beliefs about organ donation and transplantation at an urban academic HIV clinic in Baltimore, MD between 08/2016-10/2016. Responses were compared using Fisher's exact and chi-squared tests. Among 114 survey respondents, median age was 55 years, 47.8% were female, and 91.2% were African American. Most were willing to be deceased donors (79.8%) or living donors (62.3%). Most (80.7%) were aware of the US organ shortage; however, only 24.6% knew about the HOPE Act and only 21.1% were registered donors. Respondents who trusted the medical system or thought their organs would function adequately in recipients were more likely to be willing to be deceased donors (p<0.001). Respondents who were concerned about surgery, worse health post-donation, or need for changes in HIV treatment due to donation were less likely to be willing to be living donors (p<0.05 for all). Most believed that PLWH should be permitted to donate (90.4%) and that using HIV+ donor organs for transplant would reduce discrimination against PLWH (72.8%). Many of the PLWH surveyed expressed willingness to be organ donors. However, knowledge about the HOPE Act and donor registration was low, highlighting a need to increase outreach.

Where can wolves live and how can we live with them?

Mech, L. David

2017-01-01

In the contiguous 48 United States, southern Canada, and in Europe, wolves (Canis lupus) have greatly increased and expanded their range during the past few decades.They are prolific, disperse long distances, readily recolonize new areas where humans allow them, and are difficult to control when populations become established.Because wolves originally lived nearly everywhere throughout North America and Eurasia, and food in the form of wild and domestic prey is abundant there, many conservation-minded people favor wolves inhabiting even more areas.On the other hand, wolves conflict in several ways with rural residents who prefer fewer wolves. This article discusses the recovery of wolves, their benefits and values, the ways in which they conflict with humans, and the potential for their expansion into new areas.It concludes that wolf conservation will best be accomplished by each responsible political entity adaptively prescribing different management strategies for different zones within its purview.Some zones for some periods can support total protection, whereas in others, wolf numbers will have to be reduced to various degrees or removed.

Women over the age of 85 years who live alone: a descriptive study.

Foster, Pam; Neville, Stephen

2010-03-01

New Zealand as a society is ageing. This translates to an increasing number of people particularly women, over the age of 85 years. Despite many older women living alone, they are often perceived by both society and health professionals as frail and dependent. This qualitative study was designed to explore and describe experiences of older women who lived alone in the community. A qualitative descriptive methodology underpinned the study. A sample of five older women who lived alone in their own homes was interviewed. Data were analysed using a general inductive approach. Three themes emerged which reflected the reality of living by themselves: "active participation", "keeping control", and" healthy living". The information gained from describing the lives of this group of women suggests that many older women are able to live full and successful independent lives in the community. This research provides nursing with a better understanding of the realities for older women who live alone. Finally, this paper will provide nurses with some ideas about how best to support this group of people as they age.

We describe a fourth-generation paradigm: studies of assisted living technologies in their organisational, social, political and policy context. Fourth-generation studies are necessarily organic and emergent; they view technology as part of a dynamic, networked and potentially unstable system. They use co-design methods to generate and stabilise local solutions, taking account of context. SCALS (Studies in Co-creating Assisted Living Solutions) consists (currently) of 5 organisational case studies, each an English health or social care organisation striving to introduce technology-supported services to support independent living in people with health and/or social care needs. Treating these cases as complex systems, we seek to explore interdependencies, emergence and conflict. We employ a co-design approach informed by the principles of action research to help participating organisations establish, refine and evaluate their service. To that end, we are conducting in-depth ethnographic studies of people's experience of assisted living technologies (micro level), embedded in evolving organisational case studies that use interviews, ethnography and document analysis (meso level), and exploring the wider national and international context for assisted living technologies and policy (macro level).

Elderly women living alone in Spain: the importance of having children.

PubMed

Reher, David; Requena, Miguel

2017-09-01

Our goal in this paper is to analyse the extent to which completed fertility, and in particular childlessness, is a valid predictor of living alone at advanced ages, an increasingly important residential option in advanced societies with crucial implications for social policy design and the organization of welfare services. Based on micro-data from the 2011 Spanish population census, logistic regression techniques are used to assess the impact of fertility on living alone among elderly women net the effect of age, marital status, educational attainment, and other standard population controls. Our results show a clear relationship between completed fertility and living alone. Childlessness is strongly associated with living alone, while having offspring acts as a powerful buffer against living alone, particularly in larger families. A relevant conclusion of this study is that a growing deficit of family resources available for the elderly women will take place in those societies where low fertility and high rates of childlessness have prevailed in recent decades, leading to substantial growth in the number of childless elderly women and in the incidence of living alone during later life.

Making a living: gender and sustainable livelihoods.

Leach, A

2000-07-01

Humans are vulnerable to poverty in many ways, especially women. Poor people do not necessarily benefit from the way markets are managed, and women are experiencing particular barriers in making their independent living, such as low salary and access to fewer assets. In view of the above, Oxfam recognizes that in order for poor men and women to achieve sustainable livelihood they need equal access to assets and opportunities to make a living; markets need to be regulated to benefit the poor as well as the rich; and commitments need to be made to welfare services that will protect them if things go wrong. Oxfam believes that achieving sustainable development depends on creating a mix of assets, to give poor people power over markets. It will press for the effective development and regulation of markets at local, national, and global levels, to create equal opportunities for poor men and women, and to enable them to compete in markets on a fair basis. Finally, Oxfam shall lobby for recognition on the true economic and social value of household, care, and community work, and encourage producers and consumers to develop coalitions to achieve a more just and gender-equitable global economy.

To determine the level of affordability of community-directed treatment with ivermectin (CDTI) to households living in two onchocerciasis endemic Nigerian communities namely Toro in the north and Nike in the south. The proportion of the cost of treating people with ivermectin will deplete in average monthly/projected annual household expenditure on food and health care, and on average monthly and projected annual household income were respectively calculated and used to determine the level of affordability of CDTI. Questionnaires administered to heads of households or their representatives were used to collect information on the household expenditures and income. The suggested unit CDTI cost of $0.20 was used. However, as a test of sensitivity, we also used the unit cost of $0.056 which some community based distributors are charging per treatment. Using $0.20 as the unit treatment cost, this will consume less than 0.05% of average annual household income in both communities. It will equally deplete 0.05% of combined annual household expenditures on food and health care in both communities. However, using $0.056 as the unit treatment cost, then 0.02% of average annual household expenditure on health care, 0.01% average annual expenditure on combined health care and food, and 0.01% of average annual household income will be depleted. The households living in both communities may be able to afford CDTI schemes. However, the final decision on levels of affordability lies with the households. They will decide whether they can afford to trade-off some household income for ivermectin distribution.

The applicability of the magnetic resonance (MR) technique in the liquid phase is limited by poor sensitivity and short nuclear spin coherence times which are insufficient for many potential applications. Here we illustrate how it is possible to address both of these issues simultaneously by harnessing long-lived hyperpolarised spin states that are formed by adapting the Signal Amplification by Reversible Exchange (SABRE) technique. We achieve more than 4% net 1 H-polarisation in a long-lived form that remains detectable for over ninety seconds by reference to proton pairs in the biologically important molecule nicotinamide and a pyrazine derivative whose in vivo imaging will offer a new route to probe disease in the future.

In phylogenetic reconstruction the result is a tree where all taxa are leaves and internal nodes are hypothetical ancestors. In a live phylogeny, both ancestral and living taxa may coexist, leading to a tree where internal nodes may be living taxa. The well-known Neighbor-Joining heuristic is largely used for phylogenetic reconstruction. We present Live Neighbor-Joining, a heuristic for building a live phylogeny. We have investigated Live Neighbor-Joining on datasets of viral genomes, a plausible scenario for its application, which allowed the construction of alternative hypothesis for the relationships among virus that embrace both ancestral and descending taxa. We also applied Live Neighbor-Joining on a set of bacterial genomes and to sets of images and texts. Non-biological data may be better explored visually when their relationship in terms of content similarity is represented by means of a phylogeny. Our experiments have shown interesting alternative phylogenetic hypothesis for RNA virus genomes, bacterial genomes and alternative relationships among images and texts, illustrating a wide range of scenarios where Live Neighbor-Joining may be used.

Will Renewable Energy Save Our Planet?

2010-06-01

This paper discusses some important fundamental issues behind application of renewable energy (RE) to evaluate its impact as a climate change mitigation technology. The discussed issues are the following: definition of renewable energy, concentration of RE by weight and volume, generation of electrical energy and its power at unit area, electrical energy demand per unit area, life time approach vs. layman approach, energy return time, energy return ratio, CO2 return time, energy mix for RES production and use, geographical distribution of RES use, huge scale of energy shift from RES to non-RES, increase in energy consumption, Thermodynamic equilibrium of earth, and probable solutions for energy future of our energy and environmental crisis of today. The future solution (that would enable to human civilization further welfare, and good living, but with lower release of CO2 in atmosphere) may not be only RES. This will rather be an energy mix that may contain nuclear energy, non-nuclear renewable energy, or fossil energy with CO2 sequestration, efficient energy technologies, energy saving, and energy consumption decrease.

Living in a Patient-Centric Universe.

Kraus, Dennis H

2016-12-01

Patients with head and neck cancer face a number of challenges in terms of treatment, cure of their underlying malignant condition, and quality of survivorship. This presentation will focus on the patient perception of both the quality of care and the empathy and availability of the head and neck oncology team. It has become evident that the quality of survivorship plays a central role in the patient's decision-making process. The process of decision making by the patient facing head and neck cancer and the impact on treatment choices will be explored. The ability of the patient and her or his support system to navigate through the increasingly complicated health care system will be considered, with an emphasis on strategies for success. Finally, the role of the of the head and neck surgeon, and the need for physician wellness in predicating successful patient outcomes will be considered. The ultimate goal of achieving optimal care, superior patient outcomes, and patient satisfaction is the true objective of the concept of living in a patient-centric universe.

Increasingly media are asserting themselves as live. In television, this has been an important strategy and recently it has been employed by new media platforms such as Facebook, Periscope and Snapchat. This commentary explains the revival of live media by exploring the meaning and operations of the concept and argues the continued relevance of the concept for the study of social media. Traditionally, there have been three main approaches to the live in academic writing (i.e. liveness as ontology, as phenomenology and as rhetoric): each has its particular shortcoming. This paper proposes that it is more productive to understand the live as a construction that assists to secure media a central role in everyday life. PMID:29278259

Direct Force Measurements of Receptor-Ligand Interactions on Living Cells

NASA Astrophysics Data System (ADS)

Eibl, Robert H.

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

'I am doing fine only because I have not told anyone': the necessity of concealment in the lives of people living with HIV in India.

PubMed

George, Mathew Sunil; Lambert, Helen

2015-01-01

In HIV prevention and care programmes, disclosure of status by HIV-positive individuals is generally encouraged to contain the infection and provide adequate support to the person concerned. Lack of disclosure is generally framed as a barrier to preventive behaviours and accessing support. The assumption that disclosure is beneficial is also reflected in studies that aim to identify determinants of disclosure and recommend individual-level measures to promote disclosure. However, in contexts where HIV infection is stigmatised and there is fear of rejection and discrimination among those living with HIV, concealment of status becomes a way to try and regain as much as possible the life that was disrupted by the discovery of HIV infection. In this study of HIV-positive women and children in India, concealment was considered essential by individuals and families of those living with HIV to re-establish and maintain their normal lives in an environment where stigma and discrimination were prevalent. This paper describes why women and care givers of children felt the need to conceal HIV status, the various ways in which people tried to do so and the implications for treatment of people living with HIV. We found that while women were generally willing to disclose their status to their husband or partner, they were very keen to conceal their status from all others, including family members. Parents and carers with an HIV-positive child were not willing to disclose this status to the child or to others. Understanding the different rationales for concealment would help policy makers and programme managers to develop more appropriate care management strategies and train care providers to assist clients in accessing care and support without disrupting their lives.

Quality of life in elders living alone in Taiwan.

The aim of this study was to identify and describe predictors of QOL of elders who live alone in Taiwan. Despite a growing population of elders who live alone, research on their quality of life, important for policy decisions and health care provider interventions is virtually absent. A descriptive correlational design surveyed 192 Taiwanese elders living alone, selected at random from urban and rural areas. During home visits elders completed the WHO-QOL-BREF, Social Support Scale and Center for Epidemiological Studies Depression Scale (CES-D) in addition to providing demographic data. Multiple linear regressions showed that six variables predicted physical health and the psychological wellbeing QOL domains, accounting for 74.5 and 60.1% of the variance, respectively. Four variables predicted 46.7 and 34.3% of the environmental and the social relationship QOL domains, respectively. Elders who live alone in rural areas and suffer from depression are at high risk for a low quality of life. However, elders living alone reported a better quality of life than their institutionalized counterparts. Interventional research and policy decisions focused on treatment for depression and providing social support networks, as these elders age, will be particularly important. By understanding variables associated with elders' quality of life, nurses can coordinate interventions to improve their quality of life. Poorly educated rural women who live alone are particularly vulnerable. Nursing assessment of quality of life indicators and implementation of strategies for increased social support are needed for high-risk elders.

Regardless of geographic location, the cancer journey is an extremely difficult experience for both patients and their families. The aim of this literature review is to explore the impact of rural or remote residence on the supportive care needs of individuals living with cancer. This review included ten qualitative, seven quantitative, and six mixed design studies. Data collection, analysis, and evaluation were guided using a multi-domain supportive care framework based on seven domains: physical, emotional, informational, psychological, spiritual, social, and practical (Fitch, 2009). This review will suggest that there are distinct experiences that present both challenges and benefits to individuals living with cancer in rural areas. These findings will be detailed with recommendations, and grounding for future research outlined.

The ability to regulate small molecule chemistry in vivo will enable new avenues of exploration in imaging and pharmacology. However, realization of these goals will require reactions with high specificity and precise control. Here we demonstrate photocontrol over the highly specific Staudinger–Bertozzi ligation in vitro and in vivo. Our simple approach, photocaging the key phosphine atom, allows for the facile production of reagents with photochemistry that can be engineered for specific applications. The resulting compounds, which are both stable and efficiently activated, enable the spatial labeling of metabolically introduced azides in vitro and on live zebrafish. PMID:27010217

Neutron scattering to study membrane systems: from lipid vesicles to living cells.

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

Nickels, Jonathan D.; Chatterjee, Sneha; Stanley, Christopher B.

The existence and role of lateral lipid organization in biological membranes has been studied and contested for more than 30 years. Lipid domains, or rafts, are hypothesized as scalable compartments in biological membranes, providing appropriate physical environments to their resident membrane proteins. This implies that lateral lipid organization is associated with a range of biological functions, such as protein co-localization, membrane trafficking, and cell signaling, to name just a few. Neutron scattering techniques have proven to be an excellent tool to investigate these structural features in model lipids, and more recently, in living cells. I will discuss our recent workmore » using neutrons to probe the structure and mechanical properties in model lipid systems and our current efforts in using neutrons to probe the structure and organization of the bilayer in a living cell. These efforts in living cells have used genetic and biochemical strategies to generate a large neutron scattering contrast, making the membrane visible. I will present our results showing in vivo bilayer structure and discuss the outlook for this approach.« less

From Research to Application: Supportive and Therapeutic Environments for People Living With Dementia.

PubMed

Calkins, Margaret P

2018-01-18

The evidence about the role the designed and built environment plays in supporting individuals living with dementia has been steadily mounting for almost 40 years. Beginning with the work of M. Powell Lawton at the Weiss Pavilion at the Philadelphia Geriatric Center, there are now dozens of researchers who are exploring how the environment can be either supportive and therapeutic, indeed even serving as a prosthetic for various changes in cognition, or be a barrier to independent functioning and high quality of life. Two recent literature reviews published on the impact of environmental factors and characteristics on individuals living with dementia clearly delineate evidence that the environment can have a therapeutic or a debilitating impact on individuals living with dementia. Rather than duplicate these excellent reviews, this article puts the knowledge gleaned from this research into the shifting context that is long-term care. This article begins with an exploration of the evolution of approaches to the design of spaces for individuals living with dementia from traditional or medical models, to special care units (SCUs), to person-centered care (PCC), which is the organizing theme of this supplemental issue. A novel, person-centered way of conceptualizing the domains of environmental systems is then presented and used as the framework for structuring recommendations and creating supportive and therapeutic environments for individuals living with dementia. Although there are distinct pathophysiological and behavioral manifestations of different forms of dementia, there is almost no evidence that suggests alternative environmental characteristics are better for one type of dementia over another. Thus, this article will refer to "individuals living with dementia" as opposed to Alzheimer's disease or other specific forms of dementia. Further, this article only addresses residential environments: homes in the community, independent and assisted living residences

A Living Systems Perspective on Health

PubMed Central

Forrest, Christopher B

2014-01-01

Absence of a theoretical basis for defining health has made it an elusive concept and problematic to measure. This deficiency has precluded a clear delineation of the content of health science as a field. In this manuscript I use a living systems theoretical perspective to distinguish the parts and emergent properties of health. I term the parts of health, “assets,” which include the dimensions of energetics, restoration, mind, reproduction, and capabilities. Health assets interact at the level of the whole person to form integrated and emergent capacities that enable adaptation to environmental challenges, satisfaction of needs, attainment of life goals, and survival. Healthy individuals live long and adapt to and thrive within their environments. As more is learned about the interrelationships among health assets, their influences, their consequences, and how they interact to produce integrated functional capacities, a theoretically grounded and empirically informed ontology of health will emerge.

From September 2001 until March 2007, we performed 127 living-donor liver transplantations in our transplantation center. Of 127 donors, 74 were men and 53 women, of overall mean donor age of 35.2 +/- 9.3 years (range, 20-56 years). Ninety-six (75.6%) were first-degree relatives, 18 (14.1%) were second-degree relatives, and 13 (10.3%) were spouses. We performed 34 (26.7%) left hepatic lobectomies, 33 (25.3%) left lateral segmentectomies, and 60 (48%) right hepatic lobectomies. The mean percentages of remnant to donor total liver volume for the right, left, and left-lateral lobectomies were 41.7%, 67.8%, and 75.1%, respectively. The mean length of patient postoperative hospital stay was 7.4 +/- 3.1 days (range, 3-33 days). There was no postoperative mortality. Ten complications occurred in 7 of the 127 donors (5.5%). Most complications were treated with radiologic interventions. In conclusion, donor safety should be the primary focus in living-donor liver transplantation. More experience, improved surgical techniques, and meticulous donor evaluation will help to minimize morbidity and mortality for living liver donors.

Physicians' social competence in the provision of care to persons living in poverty: research protocol

PubMed Central

2010-01-01

Background The quality of the physician-patient therapeutic relationship is a key factor in the effectiveness of care. Unfortunately, physicians and people living in poverty inhabit very different social milieux, and this great social distance hinders the development of a therapeutic alliance. Social competence is a process based on knowledge, skills and attitudes that support effective interaction between the physician and patient despite the intervening social distance. It enables physicians to better understand their patients' living conditions and to adapt care to patients' needs and abilities. Methods/Design This qualitative research is based on a comprehensive design using in-depth semi-structured interviews with 25 general practitioners working with low-income patients in Montreal's metropolitan area (Québec, Canada). Physicians will be recruited based on two criteria: they provide care to low-income patients with at least one chronic illness, and are identified by their peers as having expertise in providing care to a poor population. For this recruitment, we will draw upon contacts we have made in another research study (Loignon et al., 2009) involving clinics located in poor neighbourhoods. That study will include in-clinic observations and interviews with physicians, both of which will help us identify physicians who have developed skills for treating low-income patients. We will also use the snowball sampling technique, asking participants to refer us to other physicians who meet our inclusion criteria. The semi-structured interviews, of 60 to 90 minutes each, will be recorded and transcribed. Our techniques for ensuring internal validity will include data analysis of transcribed interviews, indexation and reduction of data with software qualitative analysis, and development and validation of interpretations.

2012-06-01

The objective of the June 2010 "Workshop on Personal Motions Technologies for Healthy Independent Living" was to discuss personal motion technologies that might enable older adults and individuals with disability to live independently for longer periods. The 60 participants included clinicians, academic researchers, engineers, patient advocates, caregivers, members of the public, and federal representatives. The workshop was divided into 6 sessions that addressed the following: (1) use of technologies in identifying early indicators of disease or adverse events; (2) monitoring daily activities; (3) coping with impairment; (4) managing mild cognitive impairment; (5) rehabilitation and exercise in the home; and (6) caregiver support. Presentations and discussion focused on clinical needs, the health impact of addressing those needs, state-of-the-art technologies, and challenges to adoption of those technologies. Conclusions included the following: (1) Involvement of end-users in research and development will increase the likelihood that technologies will be adopted. (2) Integration of differing types of technology into a system that includes clinical measures is required for independent living. (3) Seniors are willing to sacrifice some privacy for an effective technology that keeps them in their homes as long as they control who receives their data. (4) Multilevel and multiscale models are needed to understand motion in the context of the environment and to design effective systems. Copyright © 2012 American Congress of Rehabilitation Medicine.

Live imaging of mitosis in the developing mouse embryonic cortex.

PubMed

Pilaz, Louis-Jan; Silver, Debra L

2014-06-04

Although of short duration, mitosis is a complex and dynamic multi-step process fundamental for development of organs including the brain. In the developing cerebral cortex, abnormal mitosis of neural progenitors can cause defects in brain size and function. Hence, there is a critical need for tools to understand the mechanisms of neural progenitor mitosis. Cortical development in rodents is an outstanding model for studying this process. Neural progenitor mitosis is commonly examined in fixed brain sections. This protocol will describe in detail an approach for live imaging of mitosis in ex vivo embryonic brain slices. We will describe the critical steps for this procedure, which include: brain extraction, brain embedding, vibratome sectioning of brain slices, staining and culturing of slices, and time-lapse imaging. We will then demonstrate and describe in detail how to perform post-acquisition analysis of mitosis. We include representative results from this assay using the vital dye Syto11, transgenic mice (histone H2B-EGFP and centrin-EGFP), and in utero electroporation (mCherry-α-tubulin). We will discuss how this procedure can be best optimized and how it can be modified for study of genetic regulation of mitosis. Live imaging of mitosis in brain slices is a flexible approach to assess the impact of age, anatomy, and genetic perturbation in a controlled environment, and to generate a large amount of data with high temporal and spatial resolution. Hence this protocol will complement existing tools for analysis of neural progenitor mitosis.

Health and urban living.

PubMed

Dye, Christopher

2008-02-08

The majority of people now live in urban areas and will do so for the foreseeable future. As a force in the demographic and health transition, urbanization is associated with falling birth and death rates and with the shift in burden of illness from acute childhood infections to chronic, noncommunicable diseases of adults. Urban inhabitants enjoy better health on average than their rural counterparts, but the benefits are usually greater for the rich than for the poor, thus magnifying the differences between them. Subject to better evidence, I suggest that the main obstacles to improving urban health are not technical or even financial, but rather are related to governance and the organization of civil society.

Changing the choice architecture of ageing: live different and 'catch old'.

PubMed

Gale, Deborah

2014-01-01

Physical ageing and being old are broadly feared or denied, particularly by the young (Chittister 2008: 53). The future is viewed in terms of vague, looming, disabilities, despite the fact that no one can know their personal, ageing fate. As physical and functional limitations become more apparent over time, expected validation occurs in support of the conventional narrative of decline. It is necessary to understand the traditional negative perceptions about ageing if we are to alter them. At present, they do not match the unfolding realities of what it means to grow old, in the early twenty-first century.The challenge of the new longevity is learning to navigate the unexplored life terrain between middle and extreme age. How, then, can we redefine this life stage, navigate new pathways for growing old in order to maximize the untapped contributions of the largest and longest ever living cohort? The baby boomers (born 1946-1964) are not homogenous but they are in position to become the standard bearers for a new narrative and an alternative way to live differently, while ageing.This will require changes to choice architecture and decision making about personal ageing that will challenge long held attitudes, perceptions and mindsets. Hence, changing the narrative about living long and well is the void addressed here.Life is ultimately terminal. In the interim, the process of catching old by living different is the ultimate, life enhancing skill. It is all in the choosing.

Simulation of Ozone and Long Lived Tracers in the GSFC Two-Dimensional Model

Fleming, Eric L.; Jackman, Charles H.; Considine, David B.; Stolarski, Richard S.

1999-01-01

The GSFC two-dimensional transport and chemistry model has been used for a wide variety of scientific and assessment studies of stratospheric ozone. Transport is a key element in the ozone simulations, and we have recently upgraded our model transport formulation to include much of the information about atmospheric transport processes available from existing data sets. To properly evaluate the model transport, it is desirable to examine the effects of transport and photochemistry separately. Recently, high quality observations of several long lived stratospheric tracers have become available from aircraft, balloon, and satellite measurement systems. This data provides a means to do a detailed model transport evaluation, as has been done in the recent Models and Measurements Intercomparison Project II. In this paper, we will discuss the GSFC 2D model simulations of ozone together with model-data comparisons of long lived tracers such as methane and the age of air transport diagnostic. We will show that the model can reproduce many of the transport-sensitive features observed in the stratosphere, and can compare reasonably well with measurements of both total ozone and long lived tracers simultaneously. We will also discuss the model deficiencies in simulating some of the detailed aspects of the observations.

2018-01-01

Since the shooting of Black teenager Michael Brown by White police officer Darren Wilson in Ferguson, Missouri, the protest hashtag #BlackLivesMatter has amplified critiques of extrajudicial killings of Black Americans. In response to #BlackLivesMatter, other Twitter users have adopted #AllLivesMatter, a counter-protest hashtag whose content argues that equal attention should be given to all lives regardless of race. Through a multi-level analysis of over 860,000 tweets, we study how these protests and counter-protests diverge by quantifying aspects of their discourse. We find that #AllLivesMatter facilitates opposition between #BlackLivesMatter and hashtags such as #PoliceLivesMatter and #BlueLivesMatter in such a way that historically echoes the tension between Black protesters and law enforcement. In addition, we show that a significant portion of #AllLivesMatter use stems from hijacking by #BlackLivesMatter advocates. Beyond simply injecting #AllLivesMatter with #BlackLivesMatter content, these hijackers use the hashtag to directly confront the counter-protest notion of "All lives matter."

Since the shooting of Black teenager Michael Brown by White police officer Darren Wilson in Ferguson, Missouri, the protest hashtag #BlackLivesMatter has amplified critiques of extrajudicial killings of Black Americans. In response to #BlackLivesMatter, other Twitter users have adopted #AllLivesMatter, a counter-protest hashtag whose content argues that equal attention should be given to all lives regardless of race. Through a multi-level analysis of over 860,000 tweets, we study how these protests and counter-protests diverge by quantifying aspects of their discourse. We find that #AllLivesMatter facilitates opposition between #BlackLivesMatter and hashtags such as #PoliceLivesMatter and #BlueLivesMatter in such a way that historically echoes the tension between Black protesters and law enforcement. In addition, we show that a significant portion of #AllLivesMatter use stems from hijacking by #BlackLivesMatter advocates. Beyond simply injecting #AllLivesMatter with #BlackLivesMatter content, these hijackers use the hashtag to directly confront the counter-protest notion of “All lives matter.” Our findings suggest that Black Lives Matter movement was able to grow, exhibit diverse conversations, and avoid derailment on social media by making discussion of counter-protest opinions a central topic of #AllLivesMatter, rather than the movement itself.

How do people live in the Anthropocene?

Robin, Libby

2016-04-01

While geologists have focused their efforts on which changes in the strata might constitute a functional shift out of the present epoch, environmental humanities scholars, museums and creative artists have taken up the Anthropocene as a concept raising new moral and practical dilemmas. A central concern is with how people adapt and live creatively in a world that is functioning beyond the physical planetary boundaries defined by the Holocene. This paper will provide an overview of the lively scholarly and popular debates on the question of what it means, ethically, to be human in an Age of Humans. Major questions include the question of who are 'we' in the Anthropocene, and how the conditions of the putative new epoch will affect 'more-than-human-others'. Creative and justice activist responses to the Anthropocene typically distinguish among humans, focusing not on the causes, but rather on concerns of the people on the receiving end of global change (for example, the Small Islands Developing States (SIDS) group of 39+8). Some are concerned about the collateral effects of technological 'fixes' for energy transformations and climate, and others about economic shifts and market-based incentives. As a historian of ideas, I explore the multiple paths by which people have come to the Anthropocene concept, and the uses to which it has already been put, even before a final decision is made on its formal status. The Anthropocene already arouses anxiety about 'the future'. One big idea that is shared across activists and scholars (and not just those in the humanities) is the question of enabling hopeful responses. A diversity of creative projects for living in the Anthropocene, which can contribute to coping with the stress of accelerating global change, is essential to this.

Assisted-living elderly and the mealtime experience.

Although there is increasing evidence of barriers to nutritional health among elderly assisted-living residents, there has not been the same emphasis when examining the ways in which these individuals experience their mealtimes, as well as the factors that they perceive as contributing to their overall sense of health and well-being. Mealtimes may be disregarded as being particularly unimportant or hurried and overlooked, especially for those residents who may be lonely and have feelings of isolation, ultimately leading to a reduced food intake and poor nutrition. A convenience sample of 38 men and women, aged ≥65 years, were selected from four assisted-living facilities in and around Montclair, NJ, USA, to participate in focus group discussions. Data were analysed using content analysis procedures. Participants described their experiences of mealtimes, and the factors contributing to an overall sense of well-being during these occasions. The ability to make healthy food choices, socialise, interact with staff, friends and family members, and enjoy a tasty meal in a warm and inviting dining environment, may provide a dignity that is unmatched by other services. The findings of the present study highlight the importance of maintaining the health of elderly assisted-living residents through strategies that enhance their mealtime experiences. Listening to the food voice of elderly through research such as that carried out in the present study will help policy makers develop a plan that will effectively deal with systemic barriers prevalent in these facilities, and incorporate strategies to motivate and encourage their residents to increase their food intake and improve their health and well-being. © 2013 The Authors Journal of Human Nutrition and Dietetics © 2013 The British Dietetic Association Ltd.

'It's a regional thing': financial impact of renal transplantation on live donors.

PubMed

McGrath, Pam; Holewa, Hamish

2012-01-01

long-term results for individuals diagnosed with end-stage renal disease. An essential element of the transplantation procedure is the voluntary donation of a healthy kidney by the live renal donor. Such an altruistic gift, which has no personal health benefit for the donor, is to be applauded and supported. The present research demonstrates that for some donors, particularly those living outside the metropolitan area, the gift may also include a range of financial costs to the donor. There is no prior research available on the financial impact of live renal donation for individuals living in non-metropolitan areas. Thus, this article is a seminal work in the area. The findings affirm 'rural disadvantage' by demonstrating that it is the live renal donors in non-metropolitan areas who are reporting financial concerns in relation to testing, hospitalisation and surgery for nephrectomy. It is the hope and expectation that the reporting on these costs will encourage further work in this area and the findings will be used for health policy and service delivery considerations.

The inverse care law persists: people living in poverty have the greatest needs and face considerable challenges in getting the care they need. Evidence reveals that GPs encounter difficulties in delivering care to poor patients, while many of those patients feel stigmatized by healthcare professionals. Patients living in poverty report negative healthcare experiences and unmet healthcare needs. Indeed, there is a growing recognition in primary care research of the importance of addressing the capabilities and social conditions of the poor when delivering care. Few studies have looked at the factors contributing to effective and "socially responsive" care for people living in poverty. Our study adopts a qualitative ethnographic approach in four healthcare organizations in deprived areas of metropolitan Montreal (Québec, Canada), using patient shadowing techniques and interviews. Data will be collected through fieldwork observations and informal interviews with patients before and after consultations. We will observe medical consultations, care organization activities, and waiting areas and reception of patients. We will conduct a total of 36 individual interviews with 12 GPs and 24 patients. The interviews will be audio-recorded and transcribed for purposes of analysis. The analysis consists of debriefing sessions, coding and interpretive analysis. This study aims to investigate how positive healthcare interactions between physicians and patients can improve the management of chronic conditions. We hypothesize that factors related to care organization, to healthcare professionals' experience and to patients may enhance the quality of healthcare interactions, which may have positive impacts for preventing and managing chronic conditions. Our study will provide a unique set of data grounded in the perspectives of healthcare professionals and of patients living in poverty.

Peltzer, Jill N; Domian, Elaine W; Teel, Cynthia S

2016-02-01

This hermeneutic phenomenological study explored the lived experiences of young African American HIV-infected women. Eleven women between the ages of 21 and 35 participated. One pattern, Infected Lives, and three themes--Living Alone With HIV, Living With Unresolved Conflicts, and Living With Multiple Layers of Betrayal--emerged. The pattern and themes portray the very complex and challenging experiences faced by these young women living with HIV infection. They have experienced isolation, abandonment, betrayal, and discrimination in their interpersonal and social systems. They often dealt with conflicts of hope and anguish in the relationships with their children, and portraying strength, while feeling fragile. These complexities negatively influence the ability to fully engage in self-care activities. Implications for future research include further investigation about the experiences of psychological distress experienced post-diagnosis, development and evaluation of holistic nursing interventions, and evaluative research on mass media educational campaigns to reduce HIV-related stigma. © The Author(s) 2014.

Living Well? Strategies Used by Women Living With Metastatic Breast Cancer.

Lewis, Sophie; Willis, Karen; Yee, Jasmine; Kilbreath, Sharon

2016-07-01

Metastatic breast cancer is a disease of changing status-once an imminent death sentence, now a chronic (albeit incurable) disease. Medical intervention advances mean women with metastatic breast cancer now have symptoms alleviated and, potentially, life extended. Living with this disease, however, requires more than a medical approach to symptoms. We were interested to know whether women manage, and if so, how, to "live well" with metastatic cancer. We conducted interviews with 18 women. Women differed in the approaches they used. Most common was the attempt to reestablish a sense of normality in their lives. However, a second group reevaluated and reprioritized their lives; and a third group was restricted in their capacity to live well because of symptoms. The findings provide the foundation for future research exploring normalization of experiences of metastatic cancer, and other chronic illnesses, where people are living with knowledge that they have contracted time. © The Author(s) 2015.

Using simulations to forecast homeowner response to sea level rise in South Florida: Will they stay or will they go?

Treuer, G.

2017-12-01

Sea level rise threatens coastal communities around the world, including South Florida which may be the most financially vulnerable region in the world. Proactive investments in sea level rise adaptive flood protections could reduce South Florida's financial vulnerability. However, it is unclear if local governments and homeowners will be willing to make those investments before it is too late. Our research explores this issue by reporting the results of a novel online simulation that accelerates 348 South Florida homeowners thirty-five years into the future so that they can `live' the effects of sea level rise. The results contain a mix of optimism and caution for the prospects of future adaptation. On the positive side over 75% of participants indicated a willingness to support bond issues to pay for adaptation, even as the costs of the measures and effects of sea level rise increased over the years. Likewise, we find little evidence that politically conservative residents who normally have more skeptical views about climate change would be any less inclined to support adaptation, or only look to information sources that downplay the threat. On the negative side, homeowner interest in moving out of the region increases steadily over time as the sea level rises. This is driven by an increase in worry associated with viewing more information within the simulation.

Although recent control measures have significantly reduced malaria cases and deaths in many endemic areas, an effective vaccine will be essential to eradicate this parasitic disease. Malaria vaccine strategies developed to date focus on different phases of the parasite's complex life cycle in the human host and mosquito vector, and include both subunit-based and whole-parasite vaccines. This review focuses on the 3 live-attenuated malaria vaccination strategies that have been tested in humans to date, and discusses their progress, challenges and the immune correlates of protection that have been identified.

Poor, powerless and pregnant. Empowering women will benefit all.

In South Africa, the better educated women have a responsibility to help out less fortunate women. The possibilities for action could include the following: literacy classes for adult women with the help of teachers, librarians, social workers, development program workers, and among church groups and adult literacy groups; and promotion campaigns to encourage mothers to keep their children in school as long as possible. Women and teenagers could be educated about the complications of teenage births and parental responsibilities. Child spacing should be encouraged as a means of achieving better health and a higher standard of living. Women must be motivated to attend family planning clinics and health education programs. Income generation programs for women could be established. Community improvement projects and new housing projects could be instrumental in improving living conditions. Leadership courses and job creation for women must be provided. These activities would highlight women as assets, such as the UN Population Fund described in its 1992 report of The State of the World. Women's high status has been found to be directly related to economic growth and higher quality of life. 7-9% of a child's mortality risk might be reduced for each year of maternal education. In Africa, the ratio of girls to boys in school attendance averages 80 girls to 100 boys in primary school and 47 girls to 100 boys in secondary school. Almost 66% of adult illiterates were women in 1985: 949 million. Early marriage and childbearing perpetuates the cycle of low status and high fertility. Where human resource development has been high, such as in Asian countries, there have been as many as 78% of women active in the labor force. In South Africa, rural women have had as many as 7 children. The growth rate was 2.3% and population has been doubling every 32 years. At the present rate, greater numbers of women will be poor and illiterate, and their children will continue the cycle.

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

NASA Astrophysics Data System (ADS)

Coker, D. J.; Graham, N. A. J.; Pratchett, M. S.

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

Supermassive Black Holes as Revealed by LISA: How Gravitational Wave Astronomy Will be a Game Changer

Astronomers now know that supermassive black holes are in nearly every galaxy.Though these black holes are an observational certainty, nearly every aspect of their evolution -- from their birth, to their fuel source, to their basic dynamics -- is a matter of lively debate. Fortunately, LISA, a space-based gravitational wave observatory set to launch in 2034, will revolutionize this field by providing data that is complementary to electromagnetic observations as well as data in regimes that are electromagnetically dark. This talk will touch on our current understanding of how SMBHs form, evolve, and alter their galaxy host, and will outline the theoretical, computational and observational work needed to make the most of LISA observations.

The tyranny of the gift: sacrificial violence in living donor transplants.

Scheper-Hughes, N

2007-03-01

Medical anthropology can bring to living donor transplant useful insights on the nature of gifting, family obligations, reciprocity and invisible sacrifice. Whereas, ethical reflections and debates on the marketing of tissues and organs, especially sales by living strangers, have proliferated to the point of saturation, the larger issue of the ethics of "altruistic" donation by and among family members is more rarely the focus of bio-ethical scrutiny and discussion today, though of course it was much debated in the early decades of kidney transplant. As the proportion of living over deceased donors (especially of kidneys) has increased markedly in the past decade, the time is ripe to revisit the topic, which I shall do via three vignettes, all of them informed by my 10 years as founding Director of Organs Watch, an independent, university-based, anthropological and ethnographic field-research and medical human rights project. Whereas living-related (altruistic) and living-unrelated (commercial) donation are often treated as very different phenomena, I will illustrate what social elements are shared. In both instances, paid kidney sellers and related donors, are often responding to family pressures and to a call to "sacrifice".

Tracking chemical changes in a live cell: Biomedical applications of SR-FTIR spectromicroscopy

DOE PAGES

Holman, Hoi-Ying N.; Martin, Michael C.; McKinney, Wayne R.

2003-01-01

Synchrotron radiation-based Fourier transform infrared (SR-FTIR) spectromicroscopy is a newly emerging bioanalytical and imaging tool. This unique technique provides mid-infrared (IR) spectra, hence chemical information, with high signal-to-noise at spatial resolutions as fine as 3 to 10 microns. Thus it enables researchers to locate, identify, and track specific chemical events within an individual living mammalian cell. Mid-IR photons are too low in energy (0.05-0.5 eV) to either break bonds or to cause ionization. In this review, we show that the synchrotron IR beam has no detectable effects on the short- and long-term viability, reproductive integrity, cell-cycle progression, and mitochondrial metabolismmore » in living human cells, and produces only minimal sample heating (<0.5°C). We will then present several examples demonstrating the application potentials of SR-FTIR spectromicroscopy in biomedical research. These will include monitoring living cells progressing through the cell cycle, including death, and cells reacting to dilute concentrations of toxins.« less

The urban population is growing at such a rate that by 2050 it is estimated that 84% of the world's population will live in cities, with flats being the most common living place. Moreover, WiFi technology is present in most developed country urban areas, with a quick growth in developing countries. New Ambient-Assisted Living applications will be developed in the near future having user positioning as ground technology: elderly tele-care, energy consumption, security and the like are strongly based on indoor positioning information. We present an Indoor Positioning System for wearable devices based on WiFi fingerprinting. Smart-watch wearable devices are used to acquire the WiFi strength signals of the surrounding Wireless Access Points used to build an ensemble of Machine Learning classification algorithms. Once built, the ensemble algorithm is used to locate a user based on the WiFi strength signals provided by the wearable device. Experimental results for five different urban flats are reported, showing that the system is robust and reliable enough for locating a user at room level into his/her home. Another interesting characteristic of the presented system is that it does not require deployment of any infrastructure, and it is unobtrusive, the only device required for it to work is a smart-watch.

FRET and BRET-based biosensors in live cell compound screens.

PubMed

Robinson, Katie Herbst; Yang, Jessica R; Zhang, Jin

2014-01-01

Live cell compound screening with genetically encoded fluorescence or bioluminescence-based biosensors offers a potentially powerful approach to identify novel regulators of a signaling event of interest. In particular, compound screening in living cells has the added benefit that the entire signaling network remains intact, and thus the screen is not just against a single molecule of interest but against any molecule within the signaling network that may modulate the distinct signaling event reported by the biosensor in use. Furthermore, only molecules that are cell permeable or act at cell surface receptors will be identified as "hits," thus reducing further optimization of the compound in terms of cell penetration. Here we discuss a detailed protocol for using genetically encoded biosensors in living cells in a 96-well format for the execution of high throughput compound screens and the identification of small molecules which modulate a signaling event of interest.

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

Wilson, Lynere; Whitehead, Lisa; Burrell, Beverley

2011-10-01

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

Photo- and electropatterning of hydrogel-encapsulated living cell arrays.

2005-01-01

Living cells have the potential to serve as sensors, naturally integrating the response to stimuli to generate predictions about cell fate (e.g., differentiation, migration, proliferation, apoptosis). Miniaturized arrays of living cells further offer the capability to interrogate many cells in parallel and thereby enable high-throughput and/or combinatorial assays. However, the interface between living cells and synthetic chip platforms is a critical one wherein the cellular phenotype must be preserved to generate useful signals. While some cell types retain tissue-specific features on a flat (2-D) surface, it has become increasingly apparent that a 3-D physical environment will be required for others. In this paper, we present two independent methods for creating living cell arrays that are encapsulated within a poly(ethylene glycol)-based hydrogel to create a local 3-D microenvironment. First, 'photopatterning' selectively crosslinks hydrogel microstructures containing living cells with approximately 100 microm feature size. Second, 'electropatterning' utilizes dielectrophoretic forces to position cells within a prepolymer solution prior to crosslinking, forming cell patterns with micron resolution. We further combine these methods to obtain hierarchical control of cell positioning over length scales ranging from microns to centimeters. This level of microenvironmental control should enable the fabrication of next-generation cellular microarrays in which robust 3-D cultures of cells are presented with appropriate physical and chemical cues and, consequently, report on cellular responses that resemble in vivo behavior.

"They are happier and having better lives than I am": the impact of using Facebook on perceptions of others' lives.

Chou, Hui-Tzu Grace; Edge, Nicholas

2012-02-01

Facebook, as one of the most popular social networking sites among college students, provides a platform for people to manage others' impressions of them. People tend to present themselves in a favorable way on their Facebook profile. This research examines the impact of using Facebook on people's perceptions of others' lives. It is argued that those with deeper involvement with Facebook will have different perceptions of others than those less involved due to two reasons. First, Facebook users tend to base judgment on examples easily recalled (the availability heuristic). Second, Facebook users tend to attribute the positive content presented on Facebook to others' personality, rather than situational factors (correspondence bias), especially for those they do not know personally. Questionnaires, including items measuring years of using Facebook, time spent on Facebook each week, number of people listed as their Facebook "friends," and perceptions about others' lives, were completed by 425 undergraduate students taking classes across various academic disciplines at a state university in Utah. Surveys were collected during regular class period, except for two online classes where surveys were submitted online. The multivariate analysis indicated that those who have used Facebook longer agreed more that others were happier, and agreed less that life is fair, and those spending more time on Facebook each week agreed more that others were happier and had better lives. Furthermore, those that included more people whom they did not personally know as their Facebook "friends" agreed more that others had better lives.

The Qinghai-Tibetan plateau: how high do Tibetans live?

PubMed

Wu, T

2001-01-01

A lower incidence of chronic mountain sickness (CMS) has apparently been observed in Tibetans in comparison to Andeans of South America. In the past, the hypothesis of "geographic differences" has been constructed to explain these population differences. In order to assess the importance of this hypothesis in the development of CMS, this article will first review the geographic factors of the Qinghai-Tibetan plateau where Tibetans live. The plateau is bounded by the Himalayas in the southwest and the Kunlun and Aljin mountains in the northeast. It towers over southwestern China at an average elevation of 4000 m above sea level and is known as "the roof of the world." Covering more than 2.5 million km(2), the Qinghai-Tibetan plateau is the highest and largest plateau in the world. The plateau has a highland continental climate and a very complex topography with great variations. Second, at what altitude do Tibetans live? In 1990 it was estimated that 4,594,188 Tibetans live on the plateau, with 53% living at an altitude over 3500 m. Fairly large numbers (about 600,000) live at an altitude exceeding 4500 m in the Chantong-Qingnan area. People of Tibetan ethnic descent are lifelong high-altitude residents and cannot easily move to higher or lower elevations. Over 90% of the population are engaged in farming and herding. The upper altitude limit of crops is around 4500 m, while the nomads reside above 4800 m and 5500 m. Recently, mining activities in the plateau have sustained a part of the population that lives permanently at altitudes between 3700 and 6000 m. Therefore, the Tibetans living in the Qinghai-Tibetan plateau live at an altitude as high as the Andeans in South America. Thus the apparently low incidence of CMS in Tibetans cannot be ascribed to "geographic differences." We propose that the genetic adaptation to hypoxia that has occurred in Tibetans is of importance in CMS.

Abating New York City transit noise: a matter of will, not way.

PubMed

Bronzaft, Arline L

2010-01-01

From the latter part of the 19th century, when New York City trains began to operate, until the present time, New York City's Transit Authority has received train noise complaints from riders and residents living near its transit system. The growing body of literature demonstrating the adverse effects of noise on physical and mental health raises the question as to whether transit noise is hazardous to the health of New York City's transit riders and residents living near the transit system. Several studies have examined the impacts of the noise of New York's transit system on hearing, health and learning. Despite the Transit Authority's efforts to remedy transit noise in response to complaints, the noise problem has not yet been satisfactorily ameliorated. This paper will suggest how the Transit Authority could employ techniques that could lower the noise levels of its system and benefit the health and welfare of New Yorkers. The recommendations in this paper could also apply to other cities with major transit systems where noise abatement has not been treated seriously.

Living alone and fall risk factors in community-dwelling middle age and older adults.

As part of a larger study on fall-related risk factors, this study investigated the relationship between living alone status and fall-related variables among community-dwelling adults who lived in a rural county in eastern North Carolina. A convenience sample of 666 community-dwelling adults ages 50 and over participated in this 4-year study and completed a fall questionnaire. Significant findings were found in relation to living alone status and experiencing a fall, who they informed about their fall, injuries, safety equipment, ambulatory devices, and personal emergency response system usage. Three hundred thirty-eight participants stated they lived alone, compared to 300 who lived with others. The percentage reporting a fall was appreciably larger for those living alone (52%) than for those living with others (48%) in both genders in all age groups except for the 61-70 year old adults where the percentage was less. Findings from this research enhance knowledge about the prevalence and contributing fall-related factors in adults who live alone compared to those who live with others. Insights gained from this research will assist community and public health leaders and health care professionals in developing more efficacious intervention strategies to prevent or reduce falls, and associated psychological and physical consequences.

In recent years much attention has been focussed on the potential of bromine-containing VSLS (very short lived substances) to contribute to stratospheric ozone depletion. This is primarily due to the large observed discrepancy between the measured inorganic bromine in the stratosphere and the amount of bromine available from known, longer lived sources gases (halons and CH3Br). In contrast, the role of very short-lived chlorine compounds (VSLS-CL) has been considered trivial because they contribute only a few percent to the total organic chlorine in the troposphere, the majority of which is supplied by long-lived compounds such as the CFCs, HCFCs, methyl chloroform and carbon tetrachloride. However recent evidence shows that one VSLS-Cl, dichloromethane (CH2Cl2) has increased by 60% over the past decade (WMO, 2014) and has already begun to offset the long-term decline in stratospheric chlorine loading caused by the reduction in emissions of substances controlled by the Montreal Protocol. We will present new VSLS-Cl measurements from recent ground-based and aircraft campaigns in SE Asia where we have observed dramatic enhancements in a number of VSLS-Cl, including CH2Cl2. Furthermore we will demonstrate how pollution from China and the surrounding region can rapidly, and regularly, be transported across the South China Sea and subsequently uplifted to altitudes of 11-12 km, the region close to the lower TTL. This process occurs frequently during the winter monsoon season and could represent a fast and efficient mechanism for transporting short-lived compounds, and other pollutants, to the lower stratosphere.

Living donor liver transplant (LDLT) is the way forward in Asia.

Rela, Mohamed; Reddy, Mettu Srinivas

2017-03-01

Living donor liver transplantation (LDLT) is currently the commonest form of liver transplantation in Asia. Efforts to improve the number of deceased donor liver transplantation have not been uniformly successful. We believe that THE unique combination of demographic, social, economic and political factors that exist in Asia will ensure that LDLT will continue to remain the predominant form of liver transplantation. While efforts to increase deceased donation rates should continue and intensify, progress in LDLT should also be supported and encouraged, as it will be the main workhorse of liver transplantation in Asia in the near and medium-term future.

Artificial Cell Therapy: New Strategies for the Therapeutic Delivery of Live Bacteria

PubMed Central

2005-01-01

There has been rapid growth in research regarding the use of live bacterial cells for therapeutic purposes. The recognition that these cells can be genetically engineered to synthesize products that have therapeutic potential has generated considerable interest and excitement among clinicians and health professionals. It is expected that a wide range of disease modifying substrates such as enzymes, hormones, antibodies, vaccines, and other genetic products will be used successfully and will impact upon health care substantially. However, a major limitation in the use of these bacterial cells is the complexity of delivering them to the correct target tissues. Oral delivery of live cells, lyophilized cells, and immobilized cells has been attempted but with limited success. Primarily, this is because bacterial cells are incapable of surviving passage through the gastrointestinal tract. In many occasions, when given orally, these cells have been found to provoke immunogenic responses that are undesirable. Recent studies show that these problems can be overcome by delivering live bacterial cells, such as genetically engineered cells, using artificial cell microcapsules. This review summarizes recent advances in the therapeutic use of live bacterial cells for therapy, discusses the principles of using artificial cells for the oral delivery of bacterial cells, outlines methods for preparing suitable artificial cells for this purpose, addresses potentials and limitations for their application in therapy, and provides insight for the future direction of this emergent and highly prospective technology.

Swindell, William R; Harper, James M; Miller, Richard A

2008-09-01

Prediction of individual life span based on characteristics evaluated at middle-age represents a challenging objective for aging research. In this study, we used machine learning algorithms to construct models that predict life span in a stock of genetically heterogeneous mice. Life-span prediction accuracy of 22 algorithms was evaluated using a cross-validation approach, in which models were trained and tested with distinct subsets of data. Using a combination of body weight and T-cell subset measures evaluated before 2 years of age, we show that the life-span quartile to which an individual mouse belongs can be predicted with an accuracy of 35.3% (+/-0.10%). This result provides a new benchmark for the development of life-span-predictive models, but improvement can be expected through identification of new predictor variables and development of computational approaches. Future work in this direction can provide tools for aging research and will shed light on associations between phenotypic traits and longevity.

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

PubMed

Lang, Jessica; Schmitz, Bernhard

2016-11-01

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

A home-based rehabilitation intervention for people living with HIV and disability in a resource-poor community, KwaZulu-Natal: study protocol for a randomised controlled trial.

In the era of highly active antiretroviral therapy HIV is now viewed as a chronic disease. Although people living with HIV are living longer lives, they are prone to a number of disabilities. Home-based rehabilitation has been shown to be an effective means of improving quality of life and function for people with a wide range of chronic diseases. There is a dearth of evidence, however, related to home-based rehabilitation interventions for people living with HIV, particularly in sub-Saharan Africa - the region with the highest global prevalence of HIV. A randomised controlled trial design will be employed. Adults living with HIV who have been on antiretroviral therapy for at least six months and with defined limited mobility will be randomly allocated to either an intervention group or the control group. Pre and post-intervention testing will be conducted at a public hospital in KwaZulu-Natal, South Africa in order to assess the participants' quality of life, perceived level of disability, functional ability and endurance. Individuals randomly allocated to the intervention group will participate in a four-month home-based rehabilitation programme, conducted once a week in their homes. This programme will be implemented by community workers who will be trained and supervised by a qualified physiotherapist. The participants in the control group will continue with the standard clinic management offered to them. On completion of the intervention, all participants will be re-assessed using the same outcome measures. Analysis of results will be carried out on intention-to-treat basis in order to identify any changes between intervention and control groups. The researchers aim to employ a novel task shifting approach to implement a needs-based home-based rehabilitation programme for people living with HIV in order to improve their quality of life and functional ability. It is hoped that this study will provide rehabilitation professionals and researchers with evidence

Synthetic mixed-signal computation in living cells

PubMed Central

Rubens, Jacob R.; Selvaggio, Gianluca; Lu, Timothy K.

2016-01-01

Living cells implement complex computations on the continuous environmental signals that they encounter. These computations involve both analogue- and digital-like processing of signals to give rise to complex developmental programs, context-dependent behaviours and homeostatic activities. In contrast to natural biological systems, synthetic biological systems have largely focused on either digital or analogue computation separately. Here we integrate analogue and digital computation to implement complex hybrid synthetic genetic programs in living cells. We present a framework for building comparator gene circuits to digitize analogue inputs based on different thresholds. We then demonstrate that comparators can be predictably composed together to build band-pass filters, ternary logic systems and multi-level analogue-to-digital converters. In addition, we interface these analogue-to-digital circuits with other digital gene circuits to enable concentration-dependent logic. We expect that this hybrid computational paradigm will enable new industrial, diagnostic and therapeutic applications with engineered cells. PMID:27255669

Living systems, such as bacteria, yeasts, and mammalian cells, can be genetically programmed with synthetic circuits that execute sensing, computing, memory, and response functions. Integrating these functional living components into materials and devices will provide powerful tools for scientific research and enable new technological applications. However, it has been a grand challenge to maintain the viability, functionality, and safety of living components in freestanding materials and devices, which frequently undergo deformations during applications. Here, we report the design of a set of living materials and devices based on stretchable, robust, and biocompatible hydrogel–elastomer hybrids that host various types of genetically engineered bacterial cells. The hydrogel provides sustainable supplies of water and nutrients, and the elastomer is air-permeable, maintaining long-term viability and functionality of the encapsulated cells. Communication between different bacterial strains and with the environment is achieved via diffusion of molecules in the hydrogel. The high stretchability and robustness of the hydrogel–elastomer hybrids prevent leakage of cells from the living materials and devices, even under large deformations. We show functions and applications of stretchable living sensors that are responsive to multiple chemicals in a variety of form factors, including skin patches and gloves-based sensors. We further develop a quantitative model that couples transportation of signaling molecules and cellular response to aid the design of future living materials and devices. PMID:28202725

This study was conducted to clarify the knowledge and attitudes of Chinese university students regarding living organ donation and analyze the determinants impacting their decisions. A questionnaire was delivered to college students chosen by random assignment. The data was analyzed by Statistics Package for Social Science (SPSS) software. Of 434 participants, 49.8% indicated they would be willing to be living organ donors, 58.4% believed living organ donation could ease the organ shortage, 48.2% thought that the recovery rate of recipients of living organ donors transplants was equal to or even better than deceased donation, 62.4% designated relatives as their most probable recipients, 48.0% argued that partial compensation was an effective method to increase live organ donation, and 53.7% wished to donate through transplantation centers. According to univariate analysis, attitudes regarding the value of life, relationship between body integrity and health as well as body integrity and conventional culture were factors that impacted on an individual's decision. Students' knowledge of the value of living organ transplantation and their economic background were considered to be determinants of individual willingness. Furthermore, the operation's impact on quality of life and postoperative complications were additional concerns. Multivariate analysis indicated that other factors influencing students' willingness to donate included attitudes toward the relationship between body integrity and health, beliefs regarding body integrity and conventional culture, value of living donor organ transplantation, economic background of students, and anxiety about the impact on postoperative complications. Numerous students were willing to participate in living organ donation. At the same time, social education and advertisements for living organ donation were far from adequate, having little or no influence on the decision-making process.

Leishmania parasites: could we consider them as living organisms per se?

PubMed

Milon, Geneviève

2008-07-01

Over the last 10 years - in Microbes and Infection - the publications dealing with protozoan parasites were mainly providing insights on the pathogenic processes leading to the local or systemic damages in the mammals, these parasitic organisms exploit/subvert as hosts. As a result, many investigators introduced the objectives of their analysis by referring to "host-pathogen" interactions. Though we, as investigators, are all determined to decipher the pathogenic processes which can indeed be coupled to the parasite uncontrolled development, I think that the parasites - alike the living organisms they subvert as hosts - need to be considered as living organisms per se, instead of being considered as "pathogens". Such a conceptual frame will promote research on the processes on which relies their perpetuation whatever the level under investigations - individual and/or population level. Only the unicellular protozoan parasites of the genus Leishmania known to be hosted by blood-feeding insects and mammals will be further considered in this brief contribution.

Educators routinely use standardized patients to teach medical students a variety of clinical concepts. Standardized patients have also been used to teach students about medical ethics and deceased organ donation. Not reported before, however, is the use of standardized patients to educate medical students about the ethical issues in living organ donation. It seems important to fill this gap because in the United States, roughly 45% of organ donors are living donors, and these patients will visit physicians throughout their lifespan, not just with the occurrence of donation. This article reports an experience teaching concepts in living donation and transplant ethics to second-year osteopathic medicine students using a standardized patient and supplementary instructional materials (eg, film, panel discussion, reading list). Specifically, a transplant ethics module was created that included an actor portraying a living donor candidate who had a number of case variables pertaining to medical and psychosocial matters. Instructional themes included informed consent, altruism, patient selection criteria, organ vending, and post-donation support systems.

Exploring talk about sexuality and living gay social lives among Chinese and South Asian gay and bisexual men in Auckland, New Zealand.

To identify ways Chinese and South Asian gay and bisexual men living in Auckland talk about issues related to sexuality and experiences of living 'gay social lives.' Results will be available to inform health policy and practice. A qualitative design with individual interviews and thematic analysis was used. Semi-structured digitally recorded interviews were undertaken with 27 Chinese and 17 South Asian gay and bisexual men living in Auckland. Four themes in the data related to talk about sexuality and living gay social lives are reported: (a) 'Happy in my skin': Being gay is Ok! (b) 'To come out or not': Managing sexual identity, (c) 'Places to go, people to see': Connecting with others, and (d) 'What's wrong with being Asian': Tolerating discrimination. There are many similarities in the ways these men talked about their identity and sexuality that can be usefully considered by health policy makers and service planners. The concept of gay (and bisexual) sexuality had some salience for the men interviewed, despite the adoption and acknowledgement of same-sex identity being a relatively new phenomenon in some Asian countries. This supports the use of these terms in local health interventions. However, as these men closely managed their gay identity and typically had not disclosed their sexuality to others, including healthcare professionals, interventions to address the skills and comfort of healthcare providers in addressing sexuality in clinical settings appear warranted to facilitate optimal healthcare. These men are not well connected with others and this has implications for HIV health promotion that is based on creating cultural norms among networks to encourage safe sex. Discrimination results in many Chinese and South Asian gay and bisexual men disengaging from connecting with others and should be addressed.

Consequently all these properties enable us to follow the evolution of the "product" of any generative process from the very beginning, in its "rising", in its "incipient" act of being born. This is why the new "operator" introduced, specifically apt when describing the above-mentioned aspects, was termed as "incipient" (or "spring") derivative.In addition, even if the considered approach was suggested by the analysis of self-organizing living Systems, some specific examples of non-living Systems will also be mentioned. In fact, what is much more surprising is that such an approach is even more valid (than the traditional one) to describe non-living Systems too. In fact the resulting "drift" between traditional solutions and "incipient" solutions led us to reconsider the phenomenon of Mercury's precessions. The satisfactory agreement with the astronomical data suggested, as a consequential hypothesis, a different interpretation of its physical origin, substantially based on the Maximum Em-Power Principle.

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

2014-01-01

As the older adult population grows and becomes more diverse, so will their needs and preferences for living environments. Many adults over 65 years of age require some assistance [1, 2]; yet it is important for their feelings of well-being that the assistance not restrict their autonomy [3]. Not only is autonomy correlated with quality of life [4], autonomy enhancement may improve functionality [2, 5]. The goal of this paper is to provide guidance for the development of technology to enhance autonomy and quality of life for older adults. We explore the potential for robotics to meet these needs. We evaluated older adults' diverse living situations and the predictors of residential moves to higher levels of care in the United States. We also examined older adults' needs for assistance with activities of daily living (ADLs), instrumental activities of daily living (IADLs), and medical conditions when living independently or in a long-term care residence. By providing support for older adults, mobile manipulator robots may reduce need-driven, undesired moves from residences with lower levels of care (i.e., private homes, assisted living) to those with higher levels of care (i.e., skilled nursing).

Public health concerns associated with care of free-living birds.

PubMed

Whittington, Julia K

2011-09-01

Free-living birds are not only susceptible to certain infectious diseases; wild bird populations serve as reservoirs of several important diseases of public health concern. Bacterial and viral diseases endemic in populations of free-living birds such as tuberculosis, avian influenza, arboviral infections, and enteropathogens have been classified as emerging or reemerging. Providing care to wild avian patients increases the opportunity for direct contact with infected birds and the possibility of transmission of infectious disease to human handlers. Awareness of disease potential is critical to disease monitoring of wild populations and will allow for the implementation of precautionary measures when working with wild avian species. Biosecurity measures designed to minimize risk must be evaluated by individual facilities.

Active living for rural youth: addressing physical inactivity in rural communities.

2009-01-01

Rural youth are at greater risk than urban youth for obesity and physical inactivity. Active living research incorporates an ecological approach to promoting physical activity (PA) by recognizing that individual behavior, social environments, physical environments, and policies contribute to behavior change. Active living research and interventions have been limited primarily to urban settings. Because rural communities have unique environmental features and sociocultural characteristics, this project combines insights from current active living models with more focused consideration of the physical and social realities of rural areas. In this study, we report on our efforts to develop, test, and refine a conceptual model describing the interaction between the individual and the environment as it enhances or thwarts active living in rural communities. Our findings revealed a host of relevant "predisposing" and "enabling" factors, including sociodemographic, environmental, policy, and programmatic elements, that extend across the four domains of active living--transportation, recreation, occupation, and household. A one-size approach to PA promotion will not fit the needs of rural youth. Given the unique challenges that rural communities face, efforts to combat childhood obesity must consider rural residents a priority population. More research, interventions, and evaluations on ways to promote rural PA are needed.

Risky business: Lived experience mental health practice, nurses as potential allies.

PubMed

Byrne, Louise; Happell, Brenda; Reid-Searl, Kerry

2017-06-01

Mental health policy includes a clear expectation that consumers will participate in all aspects of the design and delivery of mental health services. This edict has led to employment roles for people with lived experience of significant mental health challenges and service use. Despite the proliferation of these roles, research into factors impacting their success or otherwise is limited. This paper presents findings from a grounded theory study investigating the experiences of Lived Experience Practitioners in the context of their employment. In-depth interviews were conducted with 13 Lived Experience Practitioners. Risk was identified as a core category, and included sub-categories: vulnerability, 'out and proud', fear to disclose, and self-care. Essentially participants described the unique vulnerabilities of their mental health challenges being known, and while there were many positives about disclosing there was also apprehension about personal information being so publically known. Self-care techniques were important mediators against these identified risks. The success of lived experience roles requires support and nurses can play an important role, given the size of the nursing workforce in mental health, the close relationships nurses enjoy with consumers and the contribution they have made to the development of lived experience roles within academia. © 2016 Australian College of Mental Health Nurses Inc.

Background Studies aimed at understanding the association between induced abortion and HIV are scarce and differ on the direction of the association. This paper aims to show the prevalence of induced abortion in a sample of pregnancies of women living and not living with HIV/Aids, determining variables associated with pregnancy termination and linked to the life course of women and to the specific context of the pregnancy. Methods Data came from a cross-sectional study, using interviewer-administered questionnaire, developed with women that attended public health services in Porto Alegre, Brazil. A generalized estimating equation model with logit link measured the association between determinants and abortion. Findings The final sample was composed of 684 women living with HIV/Aids (2,039 pregnancies) and 639 women not living with HIV/Aids (1,539 pregnancies). The prevalence of induced abortion among pregnancies in women living with HIV/Aids was 6.5%, while in women not living with HIV/Aids was 2.9%. Among women living with HIV/Aids, the following were associated with induced abortion in the multivariable analysis: being older, having a higher education level, having had more sexual partners (i.e., variables linked to the life course of women), having had children prior to the index pregnancy and living with a sexual partner during pregnancy (i.e., variables linked to the context of each pregnancy). On the other hand, among women not living with HIV/Aids, only having a higher education level and having had more sexual partners (i.e., determinants linked to the life course of women) were associated with voluntary pregnancy termination in multivariable analysis. Conclusion Although determinants are similar between women living and not living with HIV/Aids, prevalence of induced abortion is higher among pregnancies in women living with HIV/Aids, pointing to their greater social vulnerability and to the need for public policy to address prevention and treatment of HIV

2016-01-01

This article considers the relationship between where a person lives and who they live with and their mental health and well-being. In particular, this article considers the regional locale as an important factor in understanding the perspective of a person with lived experience of mental illness. This article questions the influential, yet somewhat narrow, argument that living in the community and in the family home is somehow better for people with mental illness. The arguments presented in this article illustrate that for some people with mental illness, the issues of stigma, autonomy, and lack of alternatives (choice) are just as prevalent for them now, living in the community, as when they lived in institutions. The assumption that place alone can redress the lack of choice and autonomy is unfounded.

The urban population is growing at such a rate that by 2050 it is estimated that 84% of the world’s population will live in cities, with flats being the most common living place. Moreover, WiFi technology is present in most developed country urban areas, with a quick growth in developing countries. New Ambient-Assisted Living applications will be developed in the near future having user positioning as ground technology: elderly tele-care, energy consumption, security and the like are strongly based on indoor positioning information. We present an indoor positioning system for wearable devices based on WiFi fingerprinting. Smart-watch wearable devices are used to acquire the WiFi strength signals of the surrounding Wireless Access Points used to build an ensemble of Machine Learning classification algorithms. Once built, the ensemble algorithm is used to locate a user based on the WiFi strength signals provided by the wearable device. Experimental results for five different urban flats are reported, showing that the system is robust and reliable enough for locating a user at room level into his/her home. Another interesting characteristic of the presented system is that it does not require deployment of any infrastructure, and it is unobtrusive, the only device required for it to work is a smart-watch.

Human trophoblast syncytialization, a process of cell-cell fusion, is one of the most important yet least understood events during placental development. Investigating the fusion process in a placenta in vivo is very challenging given the complexity of this process. Application of primary cultured cytotrophoblast cells isolated from term placentas and BeWo cells derived from human choriocarcinoma formulates a biphasic strategy to achieve the mechanism of trophoblast cell fusion, as the former can spontaneously fuse to form the multinucleated syncytium and the latter is capable of fusing under the treatment of forskolin (FSK). Live-cell imaging is a powerful tool that is widely used to investigate many physiological or pathological processes in various animal models or humans; however, to our knowledge, the mechanism of trophoblast cell fusion has not been reported using a live- cell imaging manner. In this study, a live-cell imaging system was used to delineate the fusion process of primary term cytotrophoblast cells and BeWo cells. By using live staining with Hoechst 33342 or cytoplasmic dyes or by stably transfecting enhanced green fluorescent protein (EGFP) and DsRed2-Nuc reporter plasmids, we observed finger-like protrusions on the cell membranes of fusion partners before fusion and the exchange of cytoplasmic contents during fusion. In summary, this study provides the first video recording of the process of trophoblast syncytialization. Furthermore, the various live-cell imaging systems used in this study will help to yield molecular insights into the syncytialization process during placental development. © 2014 by the Society for the Study of Reproduction, Inc.

'Smart' homes and telecare for independent living.

PubMed

Tang, P; Venables, T

2000-01-01

Telecare services and 'smart' homes share a common technological base in information technology and telecommunications. There is growing interest in both telecare services and smart homes, although they have been studied in isolation. Telecare has been driven largely by perceived cost savings and improved service delivery to the home, leading to improved quality of life and independent living. Smart homes are also expected to provide better and safer living conditions. The integration of the two should produce more secure and autonomous living. There are different forms of telecare services, as there are different types of smart homes, each ranging from basic systems involving the use of alarms and the ordinary telephone to intelligent monitoring with sensors and interactive communication. The introduction of these systems has policy implications, such as the need for coordination between health, social services and housing policy makers, which will reduce duplication and inefficient allocation of resources. Successful delivery of telecare to the home is as much dependent on the construction and condition of the housing stock as it is on the ability of the care provider to meet users' needs. If the UK National Health Service (NHS) could replace a significant proportion of domiciliary nursing visits by telephone calls, then savings of up of 200 million Pounds per annum would be possible.

Self-care among older people living with chronic conditions.

LeBlanc, Raeann G; Jacelon, Cynthia S

2018-03-24

The aim of this study was to clarify the concept of self-care among older people living with chronic health conditions. This concept clarification will assist nurses in addressing self-care among older people through research, policy and practice in offering an expanded conceptual model. Several policy influences over the past decade directly relate to the increased importance and economic necessity to require self-directed care for older people living with chronic health conditions to maintain their care at home in the community. A selective review of literature on the concept of self-care included 31 sources. The Norris Concept Clarification method (1982) was used for clarification. The phenomenon is described historically according to its antecedents, attributes and consequences. A proposed definition is provided based on the clarification of this concept. A conceptual model is presented through an ecological framework. Self-care among older people living with chronic conditions is multidimensional and has multilevel influences (individual, community, system levels) and is mediated by the contexts and processes of ageing. Self-care originates along one's life course and is learned. Self-care responses are based on care needs when living with chronic health conditions. Self-care is an individual capacity, disposition and activity older people manifest in living with multiple chronic conditions. These features (capacity, disposition, action) influence one another and are hierarchical and continuous. Research, practice and policies that promote self-care among older people can focus on these features to improve health outcomes and promote new models of care consistent with personal development and chronic care needs in older age. This concept clarification can offer a model to support self-care among older people living with chronic conditions. © 2018 John Wiley & Sons Ltd.

Agency is a stunning feature of human and some wider range of life. Third, to discuss a still poorly articulated feature of life noticed by the philosopher Immanuel Kant over 200 years ago: A self propagating organization of process. We have no theory for this aspect of life, yet it is central to life. Fourth, I will discuss constraints, as in Schroedinger’s aperiodic crystal (Schroedinger E, What is life?

Structural studies on living cells by conventional methods are limited to low resolution because radiation damage kills cells long before the necessary dose for high resolution can be delivered. X-ray free-electron lasers circumvent this problem by outrunning key damage processes with an ultra-short and extremely bright coherent X-ray pulse. Diffraction-before-destruction experiments provide high-resolution data from cells that are alive when the femtosecond X-ray pulse traverses the sample. This paper presents two data sets from micron-sized cyanobacteria obtained at the Linac Coherent Light Source, containing a total of 199,000 diffraction patterns. Utilizing this type of diffraction data will require the development of new analysis methods and algorithms for studying structure and structural variability in large populations of cells and to create abstract models. Such studies will allow us to understand living cells and populations of cells in new ways. New X-ray lasers, like the European XFEL, will produce billions of pulses per day, and could open new areas in structural sciences.

Real-time Molecular Study of Bystander Effects of Low dose Low LET radiation Using Living Cell Imaging and Nanoparticale Optics

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

Natarajan, Mohan; Xu, Nancy R; Mohan, Sumathy

2013-06-03

In this study two novel approaches are proposed to investigate precisely the low dose low LET radiation damage and its effect on bystander cells in real time. First, a flow shear model system, which would provide us a near in vivo situation where endothelial cells in the presence of extra cellular matrix experiencing continuous flow shear stress, will be used. Endothelial cells on matri-gel (simulated extra cellular matrix) will be subjected to physiological flow shear (that occurs in normal blood vessels). Second, a unique tool (Single nano particle/single live cell/single molecule microscopy and spectroscopy; Figure A) will be used tomore » track the molecular trafficking by single live cell imaging. Single molecule chemical microscopy allows one to single out and study rare events that otherwise might be lost in assembled average measurement, and monitor many target single molecules simultaneously in real-time. Multi color single novel metal nanoparticle probes allow one to prepare multicolor probes (Figure B) to monitor many single components (events) simultaneously and perform multi-complex analysis in real-time. These nano-particles resist to photo bleaching and hence serve as probes for unlimited timeframe of analysis. Single live cell microscopy allows one to image many single cells simultaneously in real-time. With the combination of these unique tools, we will be able to study under near-physiological conditions the cellular and sub-cellular responses (even subtle changes at one molecule level) to low and very low doses of low LET radiation in real time (milli-second or nano-second) at sub-10 nanometer spatial resolution. This would allow us to precisely identify, at least in part, the molecular mediators that are responsible of radiation damage in the irradiated cells and the mediators that are responsible for initiating the signaling in the neighboring cells. Endothelial cells subjected to flow shear (2 dynes/cm2 or 16 dynes/cm2) and exposed to 0.1, 1

Updated data on effective and safe immunizations with live-attenuated vaccines for children after living donor liver transplantation.

Although immunizations using live-attenuated vaccines are not recommended for children post-liver transplant due to their theoretical risks, they will inevitably encounter vaccine-preventable viral diseases upon returning to real-life situations. The window of opportunity for vaccination is usually limited prior to transplantation because these children often have unstable disease courses. Also, vaccine immunity does not always persist after transplantation. Beginning in 2002, subcutaneous immunizations with four individual live-attenuated vaccines (measles, rubella, varicella, and mumps) to pediatric patients following living donor liver transplantation (LDLT) were performed for those who fulfilled the clinical criteria, including humoral and cell-mediated immunity. Written informed consent was collected. We included the study on 70 immunizations for 18 cases that we reported in 2008 (Shinjoh et al., 2008). A total of 196 immunizations were administered to 48 pediatric post-LDLT recipients. Of these, 144 were first immunizations and 52 were repeated immunizations following LDLT. The seroconversion rates at the first dose for measles (AIK-C), rubella (TO-336), varicella (Oka), and mumps (Hoshino) were 100% (36/36), 100% (35/35), 70% (23/33), and 75% (24/32), respectively. Antibody levels did not fall over time in patients immunized with rubella vaccine. Three mild cases of breakthrough varicella were observed. Two cases with transient parotid gland swelling were observed after mumps immunization. Two admissions because of fever at 2-3 weeks after the measles vaccine were reported but the patients had no symptoms of measles. Immunizations using selected live-attenuated vaccines were safe and effective for post-LDLT children who were not severely immunosuppressed. However, with the exception of rubella, repeated immunization may be necessary. Copyright © 2014 Elsevier Ltd. All rights reserved.

Population explosion is considered to be one of the most crucial problems in the world. However, in Japan, the opposite problem: population decline has become serious now. Japanese population is estimated to decrease by twenty millions in 2040. This negative situation will cause to increase areas where many residents cannot make a daily living all over Japan because many convenience living facilities such as supermarkets, convenience stores and drugstores will be difficult to maintain their market area population due to future population decline. In our research, we used point data of convenience living facilities developed by address geocoding of digital telephone directory and point data of future population projection developed by distribution of Japanese official population projection data proportionally among the building volume of digital residential map, which can monitor building volumes all over Japan. In conclusion, we estimated that various convenience living facilities in Japan will shrink and close by population decline in near future. In particular, it is cleared that approximately 14.7% of supermarkets will be possible to withdraw all over Japan by 2040. In addition, it is cleared that over 40% of supermarkets in some countryside prefectures will be possible to withdraw by 2040. Thus, we estimated future distributions of convenience living facilities that cannot maintain their market area population due to future population decline. Moreover, we estimated the number of people that they will become inconvenience in buying fresh foods.

We provide an overview of the Intended Nationally Determined Contributions (INDCs) submitted prior to the 21st meeting of the Conference of the Parties to the United Nations Framework Convention on Climate Change, which are the backbone of the Paris Climate Agreement. Two flavors of INDCs were submitted: unconditional (i.e., firm commitments) and conditional (commitments contingent on financial flow and/or technology transfer). Generally, the Paris INDCs extend to year 2030. However, achievement of either the target (1.5 °C warming) or upper limit (2.0 °C warming) of the Paris Agreement requires consideration of emissions out to 2060, due to the projected rise in energy demand, growing populations, and rising standards of living. We therefore project global carbon emissions out to year 2060, and compare to various RCP scenarios of IPCC (2013). These projections will be used to assess whether the target (1.5 °C warming) or upper limit (2.0 °) of the Paris Climate Agreement will be met.

HIV infection has been a manageable and chronic illness in Taiwan since the highly active antiretroviral therapy was introduced in 1997. HIV infection is a stigmatized disease due to its perceived association with risky behaviors. HIV often carries a negative image, and people living with HIV(PLWH) face discrimination on multiple fronts. Internalized HIV stigma impacts the spiritual health of people living with HIV in terms of increased levels of shame, self-blame, fear of disclosing HIV status, and isolation and decreased value and connections with God, others, the environment, and the self. Nursing professionals provide holistic care for all people living with HIV and value their lives in order to achieve the harmony of body, mind, and spirit. This article describes the stigma that is currently associated with HIV and how stigma-related discrimination affects the spiritual health of PLWH and then proposes how to reduce discrimination and stigma in order to improve the spiritual health of PLWH through appropriate spiritual care. Reducing HIV stigma and promoting spiritual well-being will enable Taiwan to achieve the 'Three Zeros' of zero discrimination, zero infection, and zero death advocated by the Joint United Nations Programme on HIV/AIDS for ending the AIDS epidemic in 2030.

Tele-care robot for assisting independent senior citizens who live at home.

In the last twenty years most developed countries face dramatic demographic changes, and predominantly the rapid aging of their population. As the share of elderly people is climbing while the number of care providers is declining, the aging problem is becoming an increasingly important social and economic challenge. The supply of care at home, utilizing affordable tele-care systems and smart home technologies, is one of the promising strategies to cope with challenges posed by these demographic changes. The goal of this paper is to present a tele-care robot (TCR) aimed to assist Senior citizens who live independently at their home, that need assistance in daily life activities. The idea of the proposed system is that a caregiver, operating from a central location, will be able to service between 10 to 20 patients living at their home, by using the tele-care robot. The robot will possess motion control capabilities to move inside the house of each patient and alert in case that emergency events occur. The robot will allow the care provider to communicate remotely with the patient using audio and video equipment installed on the robot. By using the robot, the caregiver will be able to examine several times during the day the well-being of the patient, his medication consumption, and his overall functionality.

The aim of the study was to understand the experience of people living with advanced-stage cancer through literature. The search included The Cochrane Library, PubMed, PsycInfo, CINAHL and Cuiden. Thirteen studies were included. A qualitative meta-synthesis was conducted. One thread emerged from the thematic synthesis: the desire to live as normally as possible, despite being aware of the proximity of death. Three themes also emerged: "a process that is unique" with its four sub-themes; "support network" and "health context," each of them having two sub-themes. This study concludes that living with advanced-stage cancer is a unique and complex process which has both positive and negative aspects. The review provides a comprehensive view of the experience, which considers the importance of the support network and the health context in which the person lives. In this study, "normalcy" is the adjustment to the new reality and living as closely as possible to the way one lived before the disease, while developing a new relationship with being finite and death. A better understanding of the experience of living with advanced-stage cancer will help health professionals to identify the needs of the patients in order to plan individual, high-quality care. © 2016 John Wiley & Sons Ltd.

Living organ donation becomes more and more important as the number of patients needing organ transplantation is increasing. The University Hospital of Erlangen initiated a survey of living kidney donors to improve the process of living donation. The survey aimed to assess the donor's needs and experiences during the process of living kidney donation. From 2003 to 2014 n=199 living kidney donations were registered at the University Hospital of Erlangen. A total of n=144 living kidney donors (65.3% females, mean age M=58.7 years) participated in the study. In general, the majority of the living kidney donors were satisfied with the process of donation. Almost all of them (98%) confirmed to donate again, if it was possible. A large part of the living kidney donors denied any negative physical or psychological consequences of the donation. However, around 25% reported still physical problems for example wound healing, pain or long-term hypertension. Furthermore, a lack of pre- and post-operative psychological care or a regular medical follow-up care was reported. Thus, clinical practice needs to be further developed to meet the patient's needs. © Georg Thieme Verlag KG Stuttgart · New York.

Governance strategies for living technologies: bridging the gap between stimulating and regulating technoscience.

PubMed

van Est, Rinie; Stemerding, Dirk

2013-01-01

The life sciences present a politically and ethically sensitive area of technology development. NBIC convergence-the convergence of nanotechnology, biotechnology, and information and cognitive technology-presents an increased interaction between the biological and physical sciences. As a result the bio-debate is no longer dominated by biotechnology, but driven by NBIC convergence. NBIC convergence enables two bioengineering megatrends: "biology becoming technology" and "technology becoming biology." The notion of living technologies captures the latter megatrend. Accordingly, living technology presents a politically and ethically sensitive area. This implies that governments sooner or later are faced with the challenge of both promoting and regulating the development of living technology. This article describes four current political models to deal with innovation promotion and risk regulation. Based on two specific developments in the field of living technologies-(psycho)physiological computing and synthetic biology-we reflect on appropriate governance strategies for living technologies. We conclude that recent pleas for anticipatory and deliberative governance tend to neglect the need for anticipatory regulation as a key factor in guiding the development of the life sciences from a societal perspective. In particular, when it is expected that a certain living technology will radically challenge current regulatory systems, one should opt for just such a more active biopolitical approach.

Reducing stillbirth and early neonatal death is a national priority in the UK. Current evidence indicates this is potentially achievable through application of four key interventions within routine maternity care delivered as the National Health Service (NHS) England's Saving Babies' Lives care bundle. However, there is significant variation in the degree of implementation of the care bundle between and within maternity units and the effectiveness in reducing stillbirth and improving service delivery has not yet been evaluated. This study aims to evaluate the impact of implementing the care bundle on UK maternity services and perinatal outcomes. The Saving Babies' Lives Project Impact and Results Evaluation (SPiRE) study is a multicentre evaluation of maternity care delivered through the Saving Babies' Lives care bundle using both quantitative and qualitative methodologies. The study will be conducted in twenty NHS Hospital Trusts and will include approximately 100,000 births. It involves participation by both service users and care providers. To determine the impact of the care bundle on pregnancy outcomes, birth data and other clinical measures will be extracted from maternity databases and case-note audit from before and after implementation. Additionally, this study will employ questionnaires with organisational leads and review clinical guidelines to assess how resources, leadership and governance may affect implementation in diverse hospital settings. The cost of implementing the care bundle, and the cost per stillbirth avoided, will also be estimated as part of a health economic analysis. The views and experiences of service users and service providers towards maternity care in relation to the care bundle will be also be sought using questionnaires. This protocol describes a pragmatic study design which is necessarily limited by the availability of data and limitations of timescales and funding. In particular there was no opportunity to prospectively gather

Sauvy, A

It has been just 2 centuries since France began to struggle seriously against mortality and excess fertility. Life expectancy, which for millenia had been under 30 years at birth, began to increase because of the discovery of effective treatments, improved production and standards of living, and access of large numbers of persons to health care. France, in the 2nd half of the 18th century, became the first country in which fertility regulation was achieved on a wide scale. The failure of England, a country of similar culture, to follow suit until a century later remains unexplained. After World War II, simple and fairly inexpensive means of mortality control, such as vaccines and water purifiers, became widely distributed throughout the developing world. These countries, which traditionally had mortality rates of 35 or 40/1000 and fertility of 40-45/1000, experienced rapid declines in mortality rates while their fertility remained constant or even increased. Because antinatal techniques diffused so much more slowly, the equilibrium of births and deaths was disturbed as rates of increase of 2 or 3% per year became common. Although the inhabitants of poor countries were not concerned, perhaps through ignorance of what was occurring, the rich countries were alarmed by the increase. Their principal objective became to spread contraception in the poor countries. The available methods at the time, however, were none too reliable. When oral contraceptive pills became available, fertility dropped to very low levels in Europe but such factors as cost and illiteracy discouraged use in many underdeveloped countries. Fertility declined in a few insular states such as Hong Kong, Taiwan, and Singapore even before the appearance of pills. Life expectancies in developing countries except a few in Africa have increased since World War II and are now higher than in Europe at the turn of the century. "Health for all by the year 2000" is an astonishing slogan for a serious

Living organ donation: an ethical evolution or evolution of ethics?

PubMed

Ghahramani, N

2010-01-01

The disparity between available and needed organs is rapidly increasing, and the number of patients dying while still on the waiting list is growing exponentially. As a partial solution to this disparity, living unrelated transplantation is being performed more frequently, and some have proposed providing financial incentives to donors. The aim of this discussion is to illustrate that with an ever-increasing number of living unrelated transplantations, society and the transplant community should adopt a more active role in developing specific strategies to scrutinize the process. The current paper will also examine the viewpoint that medical ethics is not separable from the prevailing needs of society and involves a constant balancing of often opposing goods. Issues surrounding living unrelated donor transplantation illustrate ethics as a dynamically evolving field, which is often influenced by necessity and which evolves with progression of science and society. As part of this evolution, it is the collective responsibility of society and the transplant community to devise safeguards to guarantee adherence to basic principles of ethics and to avoid "situational ethics."

Data for improvement and clinical excellence: protocol for an audit with feedback intervention in home care and supportive living.

Although considerable evidence exists about the effectiveness of audit coupled with feedback, very few audit-with-feedback interventions have been done in either home care or supportive living settings to date. With little history of audit and feedback in home care or supportive living there is potential for greater effects, at least initially. This study extends the work of an earlier study designed to assess the effects of an audit-with-feedback intervention. It will be delivered quarterly over a one-year period in seven home care offices and 11 supportive living sites. The research questions are the same as in the first study but in a different environment. They are as follows: 1. What effects do feedback reports have on processes and outcomes over time? 2. How do different provider groups in home care and supportive living sites respond to feedback reports based on quality indicator data? The research team conducting this study includes researchers and decision makers in continuing care in the province of Alberta, Canada. The intervention consists of quarterly feedback reports in 19 home care offices and supportive living sites across Alberta. Data for the feedback reports are based on the Resident Assessment Instrument Home Care tool, a standardized instrument mandated for use in home care and supportive living environments throughout Alberta. The feedback reports consist of one page, printed front and back, presenting both graphic and textual information. Reports are delivered to all employees working in each site. The primary evaluation uses a controlled interrupted time-series design, both adjusted and unadjusted for covariates. The concurrent process evaluation includes observation, focus groups, and self-reports to assess uptake of the feedback reports. The project described in this protocol follows a similar intervention conducted in our previous study, Data for Improvement and Clinical Excellence--Long-Term Care.

Many long-lived avian species adopt life strategies that involve a gregarious way of life at juvenile and sub-adult stages and territoriality during adulthood. However, the potential associated costs of these life styles, such as stress, are poorly understood. We examined the effects of group living, sex and parasite load on the baseline concentration of faecal stress hormone (corticosterone) metabolites in a wild population of common ravens (Corvus corax). Corticosterone concentrations were significantly higher in non-breeding gregarious ravens than in territorial adults. Among territorial birds, males showed higher stress levels than their mates. Parasite burdens did not affect hormone levels. Our results suggest a key role of the social context in the stress profiles of the two population fractions, and that group living may be more energetically demanding than maintaining a territory. These findings have implications for understanding hormonal mechanisms under different life styles and may inspire further research on the link between hormone levels and selective pressures modulating gregarious and territorial strategies in long-lived birds.

Periscope is a live video-streaming smartphone application (app) that allows any individual with a smartphone to broadcast live video simultaneously to multiple smartphone users around the world. The aim of this review is to describe the potential of this emerging technology for global pathology education. To our knowledge, since the launch of the Periscope app (2015), only a handful of educational presentations by pathologists have been streamed as live video via Periscope. This review includes links to these initial attempts, a step-by-step guide for those interested in using the app for pathology education, and a summary of the pros and cons, including ethical/legal issues. We hope that pathologists will appreciate the potential of Periscope for sharing their knowledge, expertise, and research with a live (and potentially large) audience without the barriers associated with traditional video equipment and standard classroom/conference settings.

Living science: Science as an activity of living beings.

PubMed

MacLennan, Bruce J

2015-12-01

The philosophy of science should accommodate itself to the facts of human existence, using all aspects of human experience to adapt more effectively, as individuals, species, and global ecosystem. This has several implications: (1) Our nature as sentient beings interacting with other sentient beings requires the use of phenomenological methods to investigate consciousness. (2) Our embodied, situated, purposeful physical interactions with the world are the foundation of scientific understanding. (3) Aristotle's four causes are essential for understanding living systems and, in particular, the final cause aids understanding the role of humankind, and especially science, in the global ecosystem. (4) In order to fulfill this role well, scientists need to employ the full panoply of human faculties. These include the consciousness faculties (thinking, sensation, feeling, intuition), and therefore, as advocated by many famous scientists, we should cultivate our aesthetic sense, emotions, imagination, and intuition. Our unconscious faculties include archetypal structures common to all humans, which can guide scientific discovery. By striving to engage the whole of human nature, science will fulfill better its function for humans and the global ecosystem. Copyright © 2015. Published by Elsevier Ltd.

Physician perceptions about living organ donation in patients with Amyotrophic Lateral Sclerosis.

PubMed

Ansari, S; Bromberg, M B; Gibson, S B

2017-09-01

Patients with Amyotrophic Lateral Sclerosis (ALS) have expressed desire to become living organ donors but are unable to do so with current organ donation policies. Our objective is to assess ALS patient's interest in organ donation, and perceived concerns of this practice by ALS neurologists. An electronic survey was administered to ALS neurologists across the United States regarding living organ donation in ALS patients prior to respiratory failure. 52 complete responses were received from 121 invites. 67% (35/52) of neurologists expressed no concerns about living organ donation in ALS patients, and 33% had concerns. The concerns related to respiratory failure, anesthesia exposure and renal dysfunction. With their concerns addressed, 71% of neurologists reported that they would endorse living organ donation. 49% of neurologists reported being asked by a patient for information regarding living organ donation. ALS neurologists felt that 22.8% of ALS patients (median 19%) would be interested in learning more about organ donation, while only 6% of neurologists broach this subject with their patients. Our results indicate that 1 in every 4 ALS patients may be interested in exploring options for living organ donation, and this topic is not routinely addressed by ALS clinics. These results indicate an unexplored area of patient interest. To honor a patient's wishes to donate, the transplant community will have to accommodate living organ donation from terminally ill patients, and address neurologist concerns. Such a practice could benefit two groups of patients. Copyright © 2017 Elsevier B.V. All rights reserved.

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

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

2016-01-01

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

The purpose of this study was to examine the prevalence of screening-detected depression and the association of depression with QoL in community-dwelling postmenopausal women living in three Asian countries. We examined self-reported questionnaires and conducted the study. A total of 698 community-dwelling postmenopausal women living in three Asian countries participated in this study. The mean age was 59.4±6.6 years (±SD) Depressive symptoms were assessed using a 15-item geriatric depression scale (GDS-15). Using the cut-off of 5/6 for the GDS-15, the percentages of subjects with depression were 39.0% of the Korean subjects, 29.2% of the Chinese subjects, and 33.9% of the Japanese subjects. For the assessment of QoL, we used the EQ-5D of the EuroQoL Group. The following five dimensions were assessed: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. The proportions of subjects reporting problems for each dimension were examined. Subjects with depression had significantly lower levels of some dimensions of QoL than those without depression in all three countries. In all three countries, 29.2-39.0% of community-dwelling postmenopausal women had screening-detected depression, which was significantly associated with a lower level of some dimensions of QoL. These results suggest that clinicians should pay more attention to depression in community-dwelling postmenopausal women. Copyright © 2010. Published by Elsevier Ireland Ltd.

High resolution quantitative phase imaging of live cells with constrained optimization approach

Pandiyan, Vimal Prabhu; Khare, Kedar; John, Renu

2016-03-01

Quantitative phase imaging (QPI) aims at studying weakly scattering and absorbing biological specimens with subwavelength accuracy without any external staining mechanisms. Use of a reference beam at an angle is one of the necessary criteria for recording of high resolution holograms in most of the interferometric methods used for quantitative phase imaging. The spatial separation of the dc and twin images is decided by the reference beam angle and Fourier-filtered reconstructed image will have a very poor resolution if hologram is recorded below a minimum reference angle condition. However, it is always inconvenient to have a large reference beam angle while performing high resolution microscopy of live cells and biological specimens with nanometric features. In this paper, we treat reconstruction of digital holographic microscopy images as a constrained optimization problem with smoothness constraint in order to recover only complex object field in hologram plane even with overlapping dc and twin image terms. We solve this optimization problem by gradient descent approach iteratively and the smoothness constraint is implemented by spatial averaging with appropriate size. This approach will give excellent high resolution image recovery compared to Fourier filtering while keeping a very small reference angle. We demonstrate this approach on digital holographic microscopy of live cells by recovering the quantitative phase of live cells from a hologram recorded with nearly zero reference angle.

Recent changes to United States law now permit people living with HIV (PLWH) to donate organs to HIV-infected (HIV+) recipients under research protocols. PLWH may have unique motivations for and concerns about living donation and understanding them is critical to ensuring the integrity of this novel approach to organ transplantation. We conducted in-depth interviews with PLWH from an urban HIV clinic who had previously indicated their willingness to be a living donor. Interviews elicited information on their motivations, perceived benefits, and concerns regarding living donation. Codes were identified inductively and then organized into themes and subthemes. Two coders independently analyzed the interviews and reconciled differences in coding by consensus. Thematic saturation was reached after 20 interviews. Motivations for living donation among PLWH included an altruistic desire to help others as well as HIV-specific motivations including solidarity with potential recipients and a desire to overcome HIV-related stigma. Perceived benefits of living donation included gratification from saving or improving the recipient's life and conferring a sense of normalcy for the HIV+ donor. Concerns about donation included the possibility of a prolonged recovery period, organ failure, and transmission of another strain of the virus to the recipients. PLWH had unique motivations, perceived benefits, and concerns about living donation in addition to those previously identified in the general population. These unique factors should be addressed in research protocols, informed consent processes, and the education and training of independent living donor advocates so that these endeavors are ethically sound.

Engineering a Live UHD Program from the International Space Station

The first-ever live downlink of Ultra-High Definition (UHD) video from the International Space Station (ISS) was the highlight of a “Super Session” at the National Association of Broadcasters (NAB) Show in April 2017. Ultra-High Definition is four times the resolution of “full HD” or “1080P” video. Also referred to as “4K”, the Ultra-High Definition video downlink from the ISS all the way to the Las Vegas Convention Center required considerable planning, pushed the limits of conventional video distribution from a space-craft, and was the first use of High Efficiency Video Coding (HEVC) from a space-craft. The live event at NAB will serve as a pathfinder for more routine downlinks of UHD as well as use of HEVC for conventional HD downlinks to save bandwidth. A similar demonstration was conducted in 2006 with the Discovery Channel to demonstrate the ability to stream HDTV from the ISS. This paper will describe the overall work flow and routing of the UHD video, how audio was synchronized even though the video and audio were received many seconds apart from each other, and how the demonstration paves the way for not only more efficient video distribution from the ISS, but also serves as a pathfinder for more complex video distribution from deep space. The paper will also describe how a “live” event was staged when the UHD video coming from the ISS had a latency of 10+ seconds. In addition, the paper will touch on the unique collaboration between the inherently governmental aspects of the ISS, commercial partners Amazon and Elemental, and the National Association of Broadcasters.

This qualitative study examined the intersection of sexual orientation and religion in the Jewish Orthodox community by exploring 22 Orthodox Jewish gay men's experiences living in secrecy. Analysis of in-depth interviews conducted with these men revealed four primary themes: emotional turmoil, ways of coping, impact on family relationships, and importance of the context. Findings from this study describe the daily struggles these men experienced keeping their homosexuality a secret. The findings suggest that in order to design effective interventions with this population, it is crucial to consider the larger community and religious context.

Implications of free will beliefs for basic theory and societal benefit: critique and implications for social psychology.

Vonasch, Andrew J; Baumeister, Roy F

2013-06-01

Greater belief in free will is associated with greater empathy towards the working poor, support for social mobility, greater desire for socio-economic equality, and less belief that poor people are fated to live in poverty. We found no sign that belief in free will led to prejudice or discrimination against poor people or undercut justice. These findings from an online survey flatly contradict the claims made by James Miles (2013). Belief in a just world did produce many of the patterns Miles attributed to belief in free will. We also question the reasoning and the strength of the purported evidence in his article, and we recommend that future writers on the topic should cultivate cautious, open-minded consideration of competing views. Miles' article is a useful reminder that to some writers, the topic of free will elicits strong emotional reactions. ©2012 The British Psychological Society.

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

2012-01-01

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

What do we know about the situation of women living with HIV in Europe?

Miralles, Celia; Mardarescu, Mariana; Sherr, Lorraine

At present, women represent approximately one-third of new diagnoses of HIV in Europe - most are infected by heterosexual transmission. Some specific populations of women, such as migrants, sex workers and those who are intravenous drug users, may be at increased risk of HIV infection. Women living with HIV face a range of intersecting situations and challenges distinct from those faced by men. The most familiar of these is pregnancy and motherhood; however, family and social situations will also be different for women compared with men, and can affect how individuals access care and manage their disease. The stigma of HIV can be a particular problem for women in many communities. Improved surveillance of HIV and increased study of the situations facing women living with HIV will help to identify improved strategies to support the care of this patient population.

Magnetic imaging is a powerful tool for probing biological and physical systems. However, existing techniques either have poor spatial resolution compared to optical microscopy and are hence not generally applicable to imaging of sub-cellular structure (e.g., magnetic resonance imaging [MRI]1), or entail operating conditions that preclude application to living biological samples while providing sub-micron resolution (e.g., scanning superconducting quantum interference device [SQUID] microscopy2, electron holography3, and magnetic resonance force microscopy [MRFM]4). Here we demonstrate magnetic imaging of living cells (magnetotactic bacteria) under ambient laboratory conditions and with sub-cellular spatial resolution (400 nm), using an optically-detected magnetic field imaging array consisting of a nanoscale layer of nitrogen-vacancy (NV) colour centres implanted at the surface of a diamond chip. With the bacteria placed on the diamond surface, we optically probe the NV quantum spin states and rapidly reconstruct images of the vector components of the magnetic field created by chains of magnetic nanoparticles (magnetosomes) produced in the bacteria, and spatially correlate these magnetic field maps with optical images acquired in the same apparatus. Wide-field sCMOS acquisition allows parallel optical and magnetic imaging of multiple cells in a population with sub-micron resolution and >100 micron field-of-view. Scanning electron microscope (SEM) images of the bacteria confirm that the correlated optical and magnetic images can be used to locate and characterize the magnetosomes in each bacterium. The results provide a new capability for imaging bio-magnetic structures in living cells under ambient conditions with high spatial resolution, and will enable the mapping of a wide range of magnetic signals within cells and cellular networks5, 6.

A brief update on the destruction of the environment is given. The concern is for the coastal waters and rivers which are polluted daily by raw sewage, industrial waste, and sedimentation, e.g., the Juru in Malaysia, the Pasig in the Philippines, and the Chao Phraya in Thailand are open sewers by the time the rivers reach the sea or bay. Metropolitan Manila's river is said to be biologically dead from pollution, and the bays of Manila and Jakarta suffer from oxygen depletion. Unfortunately, the coastal area maintains population as well as the wealth of marine life. In the US in 1990, 75% of the population will live within 50 miles of a shore including the Great Lakes. 30 southeast Asia's 50 largest cities are located on or near a coast. Over fishing, over population, over developing, and over exploitation are unacceptable; the alternative is for man to correct his mistakes.

Urban reconciliation ecology: the potential of living roofs and walls.

PubMed

Francis, Robert A; Lorimer, Jamie

2011-06-01

Reconciling human and non-human use of urban regions to support biological conservation represents a major challenge for the 21st century. The concept of reconciliation ecology, by which the anthropogenic environment may be modified to encourage non-human use and biodiversity preservation without compromising societal utilization, potentially represents an appropriate paradigm for urban conservation given the generally poor opportunities that exist for reserve establishment and ecological restoration in urban areas. Two habitat improvement techniques with great potential for reconciliation ecology in urban areas are the installation of living roofs and walls, which have been shown to support a range of taxa at local scales. This paper evaluates the reconciliation potential of living roofs and walls, in particular highlighting both ecological and societal limitations that need to be overcome for application at the landscape scale. We further consider that successful utilization of living roofs and walls for urban reconciliation ecology will rely heavily on the participation of urban citizens, and that a 'citizen science' model is needed to facilitate public participation and support and to create an evidence base to determine their effectiveness. Living roofs and walls are just one aspect of urban reconciliation ecology, but are particularly important 'bottom-up' techniques for improving urban biodiversity that can be performed directly by the citizenry.

Hospitals will send an integrated nurse home with each discharge.

Morrow, Thomas

2015-01-01

Hospitals must adapt to the rapidly changing environment of risk by changing the health behavior of their population. There is only one way to do this efficiently and at scale; send a nurse home with every patient at the time of discharge. That nurse can ensure adherence to medication and slowly, over time, transform personal behavior to evidence based levels ... basically taking their medication as prescribed, changing eating habits, increasing exercise, getting people to throw away their cigarettes, teaching them how to cope, improving their sleep and reducing their stress. But, this approach will require a nurse to basically "live" with the patient for prolonged periods of time, as bad health behaviors are quick to start but slow to change or end. The rapid developments in artificial intelligence and natural language understanding paired with cloud based computing and integrated with a variety of data sources has led to a new marketplace comprised of cognitive technologies that can emulate even the most creative, knowledgeable and effective nurse. Termed the Virtual Health Assistant, your patients can literally talk to these agents using normal conversational language. The possibility to send a nurse home with each patient to maintain adherence and prevent readmissions has arrived. The technology is available. Who will step forward to reap the rewards first?

Information and communication technologies are widely and rapidly spreading in people's daily lives. But what is the possible role of the mass proliferation of digital devices in supporting healthy living and active ageing? Are they useful in fostering personal growth and individual integration of the elderly, by promoting satisfaction, opportunities for action, and self-expression? Rather, do they enhance automation, impose constraints on personal initiative, and result in compulsive consumption of information? In this chapter, we suggest that possible answers to these questions will be offered by the "Positive Technology" approach, i.e., the scientific and applied approach to using technology so that it improves the quality of our personal experiences through its structuring, augmentation, and/or replacement. First, we suggest that it is possible to use technology to manipulate the quality of experience with the goal of increasing wellness and generating strengths and resilience in individuals, organizations, and society. Then, we classify positive technologies according to their effects on these three features of personal experience - Hedonic: technologies used to induce positive and pleasant experiences; Eudaimonic: technologies used to support individuals in reaching engaging and self-actualizing experiences; Social/Interpersonal: technologies used to support and improve the connectedness between individuals, groups, and organizations. Finally, we discuss the possible role of positive technologies for healthy living and active ageing by presenting different practical applications of this approach.

The purpose of this phenomenological qualitative study was to examine the quality of life among college students living with Type 1 diabetes (T1D). Inclusion criteria included age 18 to 24, current college student, and a diagnosis of T1D for at least 1 year. Semi-structured interviews were conducted, in-person and by phone. During these interviews, college students shared stories of living with T1D and its impact on their quality of life. Three major themes emerged, which included "planning ahead," "thinking positive," and "seeking support." These findings provide a better understanding of the transitional experience of living with T1D and the impact on perceived quality of life while attending college. Techniques and strategies aimed at the enhancement of perceived quality of life for college students living with T1D were identified. These findings will provide valuable insight for professionals working with this population. © The Author(s) 2016.

On the notion of free will in the Free Will Theorem

NASA Astrophysics Data System (ADS)

Landsman, Klaas

2017-02-01

The (Strong) Free Will Theorem (FWT) of Conway and Kochen (2009) on the one hand follows from uncontroversial parts of modern physics and elementary mathematical and logical reasoning, but on the other hand seems predicated on an undefined notion of free will (allowing physicists to "freely choose" the settings of their experiments). This makes the theorem philosophically vulnerable, especially if it is construed as a proof of indeterminism or even of libertarian free will (as Conway & Kochen suggest). However, Cator and Landsman (Foundations of Physics 44, 781-791, 2014) previously gave a reformulation of the FWT that does not presuppose indeterminism, but rather assumes a mathematically specific form of such "free choices" even in a deterministic world (based on a non-probabilistic independence assumption). In the present paper, which is a philosophical sequel to the one just mentioned, I argue that the concept of free will used in the latter version of the FWT is essentially the one proposed by Lewis (1981), also known as 'local miracle compatibilism' (of which I give a mathematical interpretation that might be of some independent interest also beyond its application to the FWT). As such, the (reformulated) FWT in my view challenges compatibilist free will à la Lewis (albeit in a contrived way via bipartite EPR-type experiments), falling short of supporting libertarian free will.

Live donor kidney transplantation (LDKT), an optimal therapy for many patients with end-stage kidney disease, is underutilized, particularly by African Americans. Potential recipient difficulties initiating and sustaining conversations about LDKT, identifying willing and medically eligible donors, and potential donors' logistical and financial hurdles have been cited as potential contributors to race disparities in LDKT. Few interventions specifically targeting these factors have been tested. We report the protocol of the Talking about Living Kidney Donation Support (TALKS) study, a study designed to evaluate the effectiveness of behavioral, educational and financial assistance interventions to improve access to LDKT among African Americans on the deceased donor kidney transplant recipient waiting list. We adapted a previously tested educational and social worker intervention shown to improve consideration and pursuit of LDKT among patients and their family members for its use among patients on the kidney transplant waiting list. We also developed a financial assistance intervention to help potential donors overcome logistical and financial challenges they might face during the pursuit of live kidney donation. We will evaluate the effectiveness of these interventions by conducting a randomized controlled trial in which patients on the deceased donor waiting list receive 1) usual care while on the transplant waiting list, 2) the educational and social worker intervention, or 3) the educational and social worker intervention plus the option of participating in the financial assistance program. The primary outcome of the randomized controlled trial will measure potential recipients' live kidney donor activation (a composite rate of live donor inquiries, completed new live donor evaluations, or live kidney donation) at 1 year.

Although lifespan is increasing, there is no evidence to suggest that older people are experiencing better health in their later years than previous generations. Nutrition, at all stages of life, plays an important role in determining health and wellbeing. A roundtable meeting of UK experts on nutrition and ageing considered key aspects of the diet-ageing relationship and developed a consensus position on the main priorities for research and public health actions that are required to help people live healthier lives as they age. The group consensus highlighted the requirement for a life course approach, recognising the multifactorial nature of the impact of ageing. Environmental and lifestyle influences at any life stage are modified by genetic factors and early development. The response to the environment at each stage of life can determine the impact of lifestyle later on. There are no key factors that act in isolation to determine patterns of ageing and it is a combination of environmental and social factors that drives healthy or unhealthy ageing. Too little is known about how contemporary dietary patterns and sedentary lifestyles will impact upon healthy ageing in future generations and this is a priority for future research. There is good evidence to support change to lifestyle (i.e. diet, nutrition and physical) activity in relation to maintaining or improving body composition, cognitive health and emotional intelligence, immune function and vascular health. Lifestyle change at any stage of life may extend healthy lifespan, although the impact of early changes appears to be greatest. © 2018 The British Dietetic Association Ltd.

More than 27,000 Australians currently live with HIV. Most of these people have access to quality clinical care and antiretroviral treatment (ART) and can expect good general health. However, HIV-related stigma is a problem and many people living with HIV experience poorer than average mental health. Issues of aging are also of increasing concern. This paper describes the methods and sample for the HIV Futures 8 study, a national survey of people living with HIV in Australia that aimed to identify factors that support health and well-being among this population. HIV Futures 8 forms part of a series of cross-sectional surveys (The "HIV Futures" studies) that have been repeated periodically since 1997. In the most recent survey, participants were able to opt into a prospective longitudinal study. HIV Futures 8 was open to people aged over 17 who were living with HIV. Data were collected in 2015/2016 using a self-complete survey that contained approximately 250 items related to physical and mental health, use of ART, HIV exposure and testing, financial security, social connectedness, relationships, life satisfaction, resilience, stigma, use of health and support services, and health literacy. To enable comparison of cross-sectional data over time, questionnaire items were consistent with those used in previous HIV Futures surveys. In HIV Futures 8, participants were invited to volunteer coded information that will allow longitudinal follow-up when participants complete subsequent HIV Futures surveys. The survey was advertised through the networks of HIV organizations, on social media and through HIV clinics and services. HIV Futures 8 was completed by 895 participants. This represents approximately 3.8% of the total number of people living with diagnosed HIV in Australia in 2014. Findings from HIV Futures 8 will contribute important insights into the complexity of factors that support physical and mental well-being among people living with HIV. The findings will also

Because of the absence of methods for tracking RNA G-quadruplex dynamics, especially the folding and unfolding of this attractive structure in live cells, understanding of the biological roles of RNA G-quadruplexes is so far limited. Herein, we report a new red-emitting fluorescent probe, QUMA-1, for the selective, continuous, and real-time visualization of RNA G-quadruplexes in live cells. The applications of QUMA-1 in several previously intractable applications, including live-cell imaging of the dynamic folding, unfolding, and movement of RNA G-quadruplexes and the visualization of the unwinding of RNA G-quadruplexes by RNA helicase have been demonstrated. Notably, our real-time results revealed the complexity of the dynamics of RNA G-quadruplexes in live cells. We anticipate that the further application of QUMA-1 in combination with appropriate biological and imaging methods to explore the dynamics of RNA G-quadruplexes will uncover more information about the biological roles of RNA G-quadruplexes. © 2018 Wiley-VCH Verlag GmbH & Co.

Living cells are remarkably complex. To unravel this complexity, living-cell assays have been developed that allow delivery of experimental stimuli and measurement of the resulting cellular responses. High-throughput adaptations of these assays, known as living-cell microarrays, which are based on microtiter plates, high-density spotting, microfabrication, and microfluidics technologies, are being developed for two general applications: (a) to screen large-scale chemical and genomic libraries and (b) to systematically investigate the local cellular microenvironment. These emerging experimental platforms offer exciting opportunities to rapidly identify genetic determinants of disease, to discover modulators of cellular function, and to probe the complex and dynamic relationships between cells and their local environment.

Recreating communities to support active living: a new role for social marketing.

PubMed

Maibach, Edward W

2003-01-01

The lack of routine physical activity has become an all too pervasive health threat in the United States. Social marketing can be used directly to promote increased physical activity among people who have access to active living options (e.g., safe and convenient sidewalks or bike paths). A second, albeit indirect, use of social marketing to promote physical activity--and the focus of this article--involves promoting behaviors that influence the built environment for the purpose of increasing people's access to active living options. This use of social marketing involves changing the behavior of consumers, developers, distribution channels (e.g., real estate agents) and policy makers. The approach offers public health and other organizations a disciplined, consumer-focused means of mobilizing their available resources in a manner that maximizes the odds of creating active living communities. These means include understanding the competition, understanding target markets, creating mutually beneficial exchanges, segmenting markets and targeting them based on anticipated return. This article identifies specific opportunities for applying the social marketing approach to create active living communities, and identifies opportunities at the state and national level that will enhance the effectiveness of local efforts.

Colon-targeted delivery of live bacterial cell biotherapeutics including microencapsulated live bacterial cells

Prakash, Satya; Malgorzata Urbanska, Aleksandra

2008-01-01

There has been an ample interest in delivery of therapeutic molecules using live cells. Oral delivery has been stipulated as best way to deliver live cells to humans for therapy. Colon, in particular, is a part of gastrointestinal (GI) tract that has been proposed to be an oral targeted site. The main objective of these oral therapy procedures is to deliver live cells not only to treat diseases like colorectal cancer, inflammatory bowel disease, and other GI tract diseases like intestinal obstruction and gastritis, but also to deliver therapeutic molecules for overall therapy in various diseases such as renal failure, coronary heart disease, hypertension, and others. This review provides a comprehensive summary of recent advancement in colon targeted live bacterial cell biotherapeutics. Current status of bacterial cell therapy, principles of artificial cells and its potentials in oral delivery of live bacterial cell biotherapeutics for clinical applications as well as biotherapeutic future perspectives are also discussed in our review.

Live-cell imaging: new avenues to investigate retinal regeneration

Lahne, Manuela; Hyde, David R.

2017-01-01

Sensing and responding to our environment requires functional neurons that act in concert. Neuronal cell loss resulting from degenerative diseases cannot be replaced in humans, causing a functional impairment to integrate and/or respond to sensory cues. In contrast, zebrafish (Danio rerio) possess an endogenous capacity to regenerate lost neurons. Here, we will focus on the processes that lead to neuronal regeneration in the zebrafish retina. Dying retinal neurons release a damage signal, tumor necrosis factor α, which induces the resident radial glia, the Müller glia, to reprogram and re-enter the cell cycle. The Müller glia divide asymmetrically to produce a Müller glia that exits the cell cycle and a neuronal progenitor cell. The arising neuronal progenitor cells undergo several rounds of cell divisions before they migrate to the site of damage to differentiate into the neuronal cell types that were lost. Molecular and immunohistochemical studies have predominantly provided insight into the mechanisms that regulate retinal regeneration. However, many processes during retinal regeneration are dynamic and require live-cell imaging to fully discern the underlying mechanisms. Recently, a multiphoton imaging approach of adult zebrafish retinal cultures was developed. We will discuss the use of live-cell imaging, the currently available tools and those that need to be developed to advance our knowledge on major open questions in the field of retinal regeneration.

2010-05-01

Intravital microscopy encompasses various optical microscopy techniques aimed at visualizing biological processes in live animals. In the last decade, the development of non-linear optical microscopy resulted in an enormous increase of in vivo studies, which have addressed key biological questions in fields such as neurobiology, immunology and tumor biology. Recently, few studies have shown that subcellular processes can be imaged dynamically in the live animal at a resolution comparable to that achieved in cell cultures, providing new opportunities to study cell biology under physiological conditions. The overall aim of this review is to give the reader a general idea of the potential applications of intravital microscopy with a particular emphasis on subcellular imaging. An overview of some of the most exciting studies in this field will be presented using resolution as a main organizing criterion. Indeed, first we will focus on those studies in which organs were imaged at the tissue level, then on those focusing on single cells imaging, and finally on those imaging subcellular organelles and structures.

Single-molecule live-cell imaging of bacterial DNA repair and damage tolerance.

Ghodke, Harshad; Ho, Han; van Oijen, Antoine M

2018-02-19

Genomic DNA is constantly under threat from intracellular and environmental factors that damage its chemical structure. Uncorrected DNA damage may impede cellular propagation or even result in cell death, making it critical to restore genomic integrity. Decades of research have revealed a wide range of mechanisms through which repair factors recognize damage and co-ordinate repair processes. In recent years, single-molecule live-cell imaging methods have further enriched our understanding of how repair factors operate in the crowded intracellular environment. The ability to follow individual biochemical events, as they occur in live cells, makes single-molecule techniques tremendously powerful to uncover the spatial organization and temporal regulation of repair factors during DNA-repair reactions. In this review, we will cover practical aspects of single-molecule live-cell imaging and highlight recent advances accomplished by the application of these experimental approaches to the study of DNA-repair processes in prokaryotes. © 2018 The Author(s).

To examine perceived control among live-in and live-out home care workers and to identify factors that contribute to perceived control among both types of caregiving. 338 migrant live-in home care workers and 185 local live-out home care workers were asked to report their perceived control. Burnout, satisfaction with the relationship with the care recipient and the care recipient's family, and satisfaction with social relationship were also gathered. Both types of caregivers reported high levels of perceived control, although live-in home care workers expressed more perceived control. Higher age, higher levels of satisfaction with the relationship with the care recipient and the care recipient's family and lower levels of burnout, predicted perceived control. Satisfaction with social relationship was a stronger predictor of one's perceived control among live-in home care workers. Promoting social relationships outside the home care context by allowing migrant live-in home care workers to take part in social gatherings is recommended as this can strengthen their sense of perceived control.

Visit http://www.cern.ch/sci-tech on 7 - 8 November to find out what modern Europeans can't live without. Seven of Europe's leading Research Organizations [1] are presenting three live Webcasts from CERN in a joint outreach programme for the European Science and Technology Week . The aim of Sci-Tech... couldn't be without it! is to show how today's society couldn't be without cutting-edge scientific research. See also ESO Press Release 05/02. Northern Europeans can't imagine their households without ovens, whereas Southern Europeans identify the refrigerator as the most essential household appliance. In the area of communications, cars and motorbikes are clearly the technologies of choice in Italy, but are regarded as less important in countries like Norway and Germany. For entertainment, the personal computer is a clear winner as the device is considered most essential by all Europeans, followed by the TV and the Internet. This hit parade of technological marvels is the result of a phone and online survey conducted by the Sci-Tech... couldn't be without it! team for this year's European Science and Technology Week on 4-10 November. The technologies Europeans could not be without, form the starting point of three entertaining and informative Webcast shows in Italian (Thursday 7 November at 10:00 CET), French (Thursday 7 November at 15:00 CET) and English (Friday 8 November at 15:00 CET), broadcast live on the Internet from a studio at CERN. During these Webcasts scientists from the seven research Organizations and their industrial partners Sun Microsystems, Siemens, L'Oreal and Luminex will engage - from the CERN studio or from remote locations through teleconference links - an audience of Internauts all over the world. The public will be taken inside their most popular gadgets to discover the science that made them possible and how vital fundamental research has been in the creation of modern technology. Fundamental science will be brought as close as possible to

Objective. To estimate the HIV prevalence and the number of people living with HIV (PLHIV) in Italy with a projection for 2020. Methods. Two methods elaborated by Joint United Nations Programme on HIV/AIDS (UNAIDS) were used: Estimate and Projection Package and Spectrum. Results. A total of 123,000 (115,000–145,000) individuals aged 15 or more were estimated to be living with HIV in Italy at the end of 2012 and the estimated HIV prevalence was 0.28 (0.24–0.32) per 100 residents aged 15 or more. In 2012, the estimated number of new HIV infections among adults was 3,000 (2,700–4,000), and the number of adults in need for ART was 93,000 (80,000–110,000). The projection estimates that 130,000 (110,000–150,000) adults will live with HIV/AIDS in 2020 in Italy. Conclusion. Estimates of PLHIV in Italy stress the high number of PLHIV in need of care and treatment, as well as the need for more information and prevention campaigns. PMID:25136562

The last will and testament in literature: rupture, rivalry, and sometimes rapprochement from Middlemarch to Lemony Snicket.

PubMed

Stone, Elizabeth

2008-12-01

Although the psychological literature on the last will and testament is sparse, authors of fiction and memoir have filled the gap, writing in rich detail about the impact of wills on families. Henry James, George Eliot, J. R. Ackerley, and others reveal that a will is not only a legal document but a microcosm of family life: a coded and non-negotiable message from the will's writer to its intended readers, the heirs, delivered at a stressful time and driving home the truth that options for discussion between testator and heirs are now gone, all factors which may intensify the ambivalence of grief and stall its resolution. Among the problems the authors chronicle: reinvigorated sibling rivalries, vindictive testators, and the revelation of traumatic family secrets. Writers also demonstrate how contemporary social factors, such as divorce, second families, and geographic distance between family members, may complicate wills and ensuing family relations. Exemplary wills, or will-like documents, appear in fiction by Maria Katzenbach and Marilynne Robinson, allowing the living to make rapprochements with the dead, and pointing to testamentary strategies clinicians might develop to lead to a resolution of grief. The depth of these writers' accounts allows clinicians to imagine points at which they might productively intervene in matters pertaining to a will.

Free will in addictive behaviors: A matter of definition.

PubMed

Cox, W Miles; Klinger, Eric; Fadardi, Javad Salehi

2017-06-01

Certain people are at risk for using alcohol or other drugs excessively and for developing problems with their use. Their susceptibility might arise from a variety of factors, including their genetic make-up, brain chemistry, family background, personality and other psychological variables, and environmental and sociocultural variables. Moreover, after substance use has become established, there are additional cognitive-motivational variables (e.g., substance-related attentional bias) that contribute to enacting behaviors consistent with the person's motivation to acquire and use the substance. People who are at such risk are likely to choose to use addictive substances even though doing so entails negative consequences. In the sense of complete freedom from being determined by causal factors, we believe that there is no such thing as free will, but defined as ability to make choices from among multiple options, even though the choices are ultimately governed by natural processes, addicted individuals are free to choose. Although they might appear unable to exercise this kind of free will in decisions about their substance use, addictive behaviors are ultimately always goal-directed and voluntary. Such goal pursuits manifest considerable flexibility. Even some severely addicted individuals can cease their use when the value of continuing the use abruptly declines or when the subjective cost of continuing the use is too great with respect to the incentives in other areas of their lives. Formal treatment strategies (e.g., contingency management, Systematic Motivational Counseling, cognitive training) can also be used to facilitate this reversal.

Ethics and commerce in live donor renal transplantation: classification of the issues.

Daar, A S; Salahudeen, A K; Pingle, A; Woods, H F

1990-06-01

Renal transplantation is now very successful. A shortage of kidneys continues to be a problem. Attempts to increase the supply have recently led to unethical practices, but the issues in the discussion of the ethics need clarification. We propose a classification that we believe will help to achieve this for living donor renal transplantation. This can be considered under five categories: (1) living-related donation; (2) emotionally related donation; (3) altruistic donation; (4) "rewarded" gifting; and (5) rampant commercialism. Ethical issues for categories 1, 2, and 3 are either esoteric or have been resolved. Category 4 needs further discussion and elucidation and should be the area of concentration. Category 5 we perceive to be unethical.

Protein and Overtraining: Potential Applications for Free-Living Athletes

PubMed Central

Lowery, Lonnie; Forsythe, Cassandra E

2006-01-01

Despite a more than adequate protein intake in the general population, athletes have special needs and situations that bring it to the forefront. Overtraining is one example. Hard-training athletes are different from sedentary persons from the sub-cellular to whole-organism level. Moreover, competitive, "free-living" (less-monitored) athletes often encounter negative energy balance, sub-optimal dietary variety, injuries, endocrine exacerbations and immune depression. These factors, coupled with "two-a-day" practices and in-season demands require that protein not be dismissed as automatically adequate or worse, deleterious to health. When applying research to practice settings, one should consider methodological aspects such as population specificity and control variables such as energy balance. This review will address data pertinent to the topic of athletic protein needs, particularly from a standpoint of overtraining and soft tissue recovery. Research-driven strategies for adjusting nutrition and exercise assessments will be offered for consideration. Potentially helpful nutrition interventions for preventing and treating training complications will also be presented. PMID:18500962

2009-03-01

The ongoing development of live donor kidney transplant has generated many ethical dilemmas. It is important to be aware of the attitudes of transplant professionals involved in this practice. An anonymous and confidential questionnaire was sent to 236 members of the medical and nursing staff of the West London Renal and Transplant Centre, to assess their views on the ethics of the current practice of live donor kidney transplant. Of the 236 questionnaires, 108 (45.8%) were returned. Respondents considered live donor kidney transplant ethically acceptable between blood relatives (100%), nonblood relatives and friends (92.6%), and strangers (47.2%). Most respondents were willing to donate a kidney to a blood relative (92.6%) or a nonblood relative or friend (81.5%), and 12.0% were willing to donate to a stranger. Considering themselves as potential recipients if they had end-stage renal disease, most would accept a kidney from a blood relative (91.7%) or nonblood relative or friend (85.2%),while 44.5% would accept a kidney from a stranger. The highest number of respondents (43.5%) believed that the recipient should approach the potential donor. About one-third believed there should be no financial reward, not even compensation for expenses, for donors; 8% favored direct financial rewards for donors known to recipients, and 18% favored rewards for donors not known to recipients. Slightly more than half were in favor of accepting donors with mild to moderate medical problems. Live related and unrelated kidney donation are considered ethically acceptable procedures, and nondirected donation is gaining support among transplant professionals. A substantial minority favored direct financial rewards for donors, especially in the case of nondirected donation.

Protein-protein interactions control transcription, cell division, and cell proliferation as well as mediate signal transduction, oncogenic transformation, and regulation of cell death. Although a variety of methods have been used to investigate protein interactions in vitro and in cultured cells, none can analyze these interactions in intact, living animals. To enable noninvasive molecular imaging of protein-protein interactions in vivo by positron-emission tomography and fluorescence imaging, we engineered a fusion reporter gene comprising a mutant herpes simplex virus 1 thymidine kinase and green fluorescent protein for readout of a tetracycline-inducible, two-hybrid system in vivo. By using micro-positron-emission tomography, interactions between p53 tumor suppressor and the large T antigen of simian virus 40 were visualized in tumor xenografts of HeLa cells stably transfected with the imaging constructs. Imaging protein-binding partners in vivo will enable functional proteomics in whole animals and provide a tool for screening compounds targeted to specific protein-protein interactions in living animals.

Live cell imaging of Argonaute proteins in mammalian cells.

PubMed

Pare, Justin M; Lopez-Orozco, Joaquin; Hobman, Tom C

2011-01-01

The central effector of mammalian RNA interference (RNAi) is the RNA-induced silencing complex (RISC). Proteins of the Argonaute family are the core components of RISC. Recent work from multiple laboratories has shown that Argonaute family members are associated with at least two types of cytoplasmic RNA granules: GW/Processing bodies and stress granules. These Argonaute-containing granules harbor proteins that function in mRNA degradation and translational repression in response to stress. The known role of Argonaute proteins in miRNA-mediated translational repression and siRNA-directed mRNA cleavage (i.e., Argonaute 2) has prompted speculation that the association of Argonautes with these granules may reflect the activity of RNAi in vivo. Accordingly, studying the dynamic association between Argonautes and RNA granules in living cells will undoubtedly provide insight into the regulatory mechanisms of RNA-based silencing. This chapter describes a method for imaging fluorescently tagged Argonaute proteins in living mammalian cells using spinning disk confocal microscopy.

It has long been recognized that microorganisms play a central role in our lives. By beating the diffraction limit that restricts traditional light microscopy, single-molecule fluorescence imaging is a precise, noninvasive way to sensitively probe position and dynamics, even in living cells. We are pioneering this super-resolution imaging method for unraveling important biological processes in live bacteria, and I will discuss how we infer function from subcellular dynamics (Tuson and Biteen, Analytical Chemistry 2015). In particular, we have understood the mechanism of membrane-bound transcription regulation in the pathogenic Vibrio cholerae, revealed an intimate and dynamic coupling between DNA mismatch recognition and DNA replication, and measured starch utilization in an important member of the human gut microbiome.

Fluorescence Live Cell Imaging

2014-01-01

Fluorescence microscopy of live cells has become an integral part of modern cell biology. Fluorescent protein tags, live cell dyes, and other methods to fluorescently label proteins of interest provide a range of tools to investigate virtually any cellular process under the microscope. The two main experimental challenges in collecting meaningful live cell microscopy data are to minimize photodamage while retaining a useful signal-to-noise ratio, and to provide a suitable environment for cells or tissues to replicate physiological cell dynamics. This chapter aims to give a general overview on microscope design choices critical for fluorescence live cell imaging that apply to most fluorescence microscopy modalities, and on environmental control with a focus on mammalian tissue culture cells. In addition, we provide guidance on how to design and evaluate fluorescent protein constructs by spinning disk confocal microscopy. PMID:24974023

2014-06-02

In spite of the wide application potential of 1,2,4,5-tetrazines, particularly in live-cell and in vivo imaging, a major limitation has been the lack of practical synthetic methods. Here we report the in situ synthesis of (E)-3-substituted 6-alkenyl-1,2,4,5-tetrazine derivatives through an elimination-Heck cascade reaction. By using this strategy, we provide 24 examples of π-conjugated tetrazine derivatives that can be conveniently prepared from tetrazine building blocks and related halides. These include tetrazine analogs of biological small molecules, highly conjugated buta-1,3-diene-substituted tetrazines, and a diverse array of fluorescent probes suitable for live-cell imaging. These highly conjugated probes show very strong fluorescence turn-on (up to 400-fold) when reacted with dienophiles such as cyclopropenes and trans-cyclooctenes, and we demonstrate their application for live-cell imaging. This work provides an efficient and practical synthetic methodology for tetrazine derivatives and will facilitate the application of conjugated tetrazines, particularly as fluorogenic probes for live-cell imaging. © 2014 WILEY-VCH Verlag GmbH & Co.

Bear bile is a traditional Chinese medicine that has been used for millennia. Several arguments support and oppose the use of bear farming in terms of conservation and nonhuman animal welfare. This study involved designing a questionnaire and surveying a random sample of general citizens and college students in Beijing to elicit their attitudes on bile extraction from living bears. Older people and people with lower education levels used more bear bile medicines. In total, 29.47% (n = 204) of citizens and 23.14% (n = 81) of students surveyed used bear bile medicine since 1990. Students were less willing to use bear bile medicines than citizens (p < .05). The level the respondents agreed with the blue side (against the extraction of bile from living bears; anti for short) was significantly higher than that for the red side (support the extraction of bile from living bears; pro for short; p < .05). Additionally, college students had a more distinct attitude toward the opposing views, which indicates they were more inclined to oppose bile extraction from living bears.

Live bacterial vaccines represent a highly valid preventive strategy in the fight against infectious disease. However, the road from research to market is peppered with hurdles, one of which is the requirement for high biosafety characteristics, which the candidate vaccine has to display. In Europe, the European Agency for the evaluation of medicinal products (EMEA) is the relevant authority regulating the licensure of genetically engineered vaccines. For this purpose, the agency may rely on several directives and guidelines defined in the past 15 years. As for live vaccines containing genetically modified organisms (GMOs) susceptible to be released into the environment, Directive 2001/18/EC determines the framework and principles of an environmental risk assessment (ERA) process, the results of which constitute an important section of the vaccine registration package submitted to registration authorities. In this article, we address the implications of current European regulations for the approval of live oral bacterial vaccines with emphasis on the assessment of potential risks associated with environmental release. Biosafety aspects of already registered and some promising live bacterial vaccine strains will be briefly discussed.

Disaster management mobile protocols: a technology that will save lives.

Although training and education have long been accepted as integral to disaster preparedness, many currently taught practices are neither evidence based nor standardized. The need for effective evidence-based disaster education for healthcare workers at all levels in the multidisciplinary medical response to major events has been designated by the disaster response community as a high priority. This article describes a disaster management mobile application of systematic evidence-based practice. The application is interactive and comprises portable principles, algorithms, and emergency protocols that are agile, concise, comprehensive, and response relevant to all healthcare workers. Early recognition through clinical assessment versus laboratory and diagnostic procedures in chemical, biological, radiological, and nuclear (CBRNE) exposures grounded in an evidence-based skill set is especially important. During the immediate threat, the clinical diagnosis can get frustrating because CBRNE casualties can mimic everyday healthcare illnesses and initially present with nonspecific respiratory or flu-like symptoms. As there is minimal time in a catastrophic event for the medical provider to make accurate decisions, access to accurate, timely, and comprehensive information in these situations is critical. The CBRNE mobile application is intended to provide a credible source for treatment and management of numerous patients in an often intimidating environment with scarce resources and overwhelming tasks.

This article describes interactive learning about independent living for people with disabilities and features the partnership of the College of Nursing and a Center for Independent Living (CIL). Using qualitative descriptive approach, students' written reflections were analyzed. Through "Xtreme Challenge," 82 undergraduate nursing students participated in aspects of independent living as well as identifying barriers. Students were engaged and learned to consider the person before the disability. Moreover, students valued the activity leaders' openness, which facilitated understanding the point of view of a person with disability. The value of partnership was evident as it allowed students to participate in active learning, which led to growth in the affective domain. Students became aware of potential education resources through the CIL. This article will guide educators in designing experiences that teach nursing care at the individual, family, and community level for people living with disabilities. © 2015 Association of Rehabilitation Nurses.

Volition and will in psychoanalysis.

PubMed

Meissner, W W

2009-10-01

To clarify the role and function of the will in psychoanalytic theory and praxis, the use and meaning of the concept of will are traced in the philosophical tradition influencing Freud, in Freud's own view of will, and in the subsequent history of psychoanalysis. Functions of the will relevant to psychoanalysis are described in terms of intellective preference and executive functioning. Operations of will as an executive function of the ego-self are analyzed, emphasizing will as efficient cause of motivated actions. The will functions to decide, choose, and initiate action directed to motivationally determined goals. The conclusion is drawn that will action is determined and directed by motivational influences, and that will decision and choice, while predominantly secondary process in organization, can operate consciously or unconsciously. Expressions of will action in psychopathology and in the analytic process are briefly discussed.

Morphological and immunofluorescent study of changes in the central nervous system of monkeys with mumps was carried out in order to determine the criteria of neurovirulence of different mumps virus strains. Quantitative evaluation showed a lower residual neurovirulence of L-3 strain vs. Jeryl Lynn and Urabe Am9 strains. Use of new methodological approaches to evaluation of mumps vaccine strain neurovirulence will improve the safety control of live mumps vaccines.

A microRNA-initiated DNAzyme motor operating in living cells

Synthetic DNA motors have great potential to mimic natural protein motors in cells but the operation of synthetic DNA motors in living cells remains challenging and has not been demonstrated. Here we report a DNAzyme motor that operates in living cells in response to a specific intracellular target. The whole motor system is constructed on a 20 nm gold nanoparticle (AuNP) decorated with hundreds of substrate strands serving as DNA tracks and dozens of DNAzyme molecules each silenced by a locking strand. Intracellular interaction of a target molecule with the motor system initiates the autonomous walking of the motor on the AuNP. An example DNAzyme motor responsive to a specific microRNA enables amplified detection of the specific microRNA in individual cancer cells. Activated by specific intracellular targets, these self-powered DNAzyme motors will have diverse applications in the control and modulation of biological functions.

Organ and tissue donation: are minorities willing to donate?

Daniels, D E; Smith, K; Parks-Thomas, T; Gibbs, D; Robinson, J

1998-01-01

The Task Force on Organ Transplantation (DHHS,1986) addressed the issue of increasing organ donation. The Report of the Task Force recommended that "educational efforts aimed at increasing organ donation among minority populations be developed and implemented, so that the donor population will more closely reflect the ethnicity of potential transplant recipients, in order to gain the advantage of improved donor and recipient immunologic matching (DHHS,1986). Donor rates for minorities has increased as follows: 16% in 1988 to 23% in 1995 among cadaveric donors and 24% in 1988 to 28% in 1995 among living donors. The improvement in donor rates among minorities may positively affect the transplantation success rate experienced by organ recipients of the same race. Strategies must be implemented that will increase the effectiveness and frequency of communication between minority patients and the medical community. An increase in the effectiveness of communication between potential minority donor families and the health care community will contribute to the process of Consciousness Raising as discussed by Prochasksa. The result of increased awareness of the organ donation and transplantation process may have a favorable impact on organ donation. The media has, through public service announcements, paid advertising and entertainment programming, attempted to promote discussion of organ donation in the community and within families. Johnson et al. discussed Mexican-American and Anglo-American Attitudes Toward Organ Donation. The primary impediment contributing to the disparity of consent rates between Mexican-American and Anglo-American population occurs with regard to the donation of organs of relatives. Johnson stated that this impediment to organ donation can be effectively addressed by promoting family discussion. Communication within families will inform surviving next of kin of the desire of the deceased to be an organ donor and hence improve the likelihood of the

In 2003, the Haitian Study Group on Kaposi's Sarcoma and Opportunistic Infections (GHESKIO), a nonprofit organization, began administering antiretroviral therapy (ART) to its patients. This practice transformed HIV from a fatal disease to a more manageable chronic condition. However, relatively few studies focus on the experiences of survivors. This study provided a unique opportunity to interview patients who survived at least 10 years after being treated with ART at GHESKIO. The goal of the study was to elicit from patients their perspectives on what enabled them to survive with AIDS. Grounded Theory, a qualitative research method was used to guide data collection, coding, and analysis. Individual interviews were conducted, audio-taped, transcribed and analyzed in Creole, and translated into English. Data saturation was reached at 25 participants. Of which, 64% were women, the mean age was 49, range of 43-55 years, 24% were married, 44% had not completed elementary school, and 72% had no income, the remaining participants had incomes ranging from $1000 to $5000 annually. Qualitative analysis resulted in 681 codes, which were grouped into six categories: being spiritually grounded, having supportive interactions with providers, caring for children, setting personal goals, persevering and living life as usual, and maintaining strict medication adherence practices. The overarching theory was that having a reason to live despite one's circumstances and living life as usual enabled one to survive. Having a strong spiritual foundation coupled with supportive family and providers motivated participants to live and adhere to their ART. As the number of patients who are living longer with HIV in Haiti increases, results from this study will be important in helping tailor interventions that enhance their overall quality of life.

Patients with lymphoma are at risk of experiencing adverse physical and psychosocial problems from their cancer and its treatment. Regular screening of these symptoms by the use of patient-reported outcomes (PROs) could increase timely recognition and adequate symptom management. Moreover, self-management interventions intend to enhance knowledge and skills and empower patients to better manage their disease and related problems. The objective of the Lymphoma InterVEntion (LIVE) trial is to examine whether feedback to patients on their PROs and access to a web-based, self-management intervention named Living with lymphoma will increase self-management skills and satisfaction with information, and reduce psychological distress. The LIVE randomised controlled trial consists of three arms: (1) standard care, (2) PRO feedback, and (3) PRO feedback and the Living with lymphoma intervention. Patients who have been diagnosed with Hodgkin lymphoma, non-Hodgkin lymphoma, including chronic lymphocytic leukaemia, as registered in the Netherlands Cancer Registry in various hospitals will be selected for participation. Patients are invited via their haemato-oncologist 6 to 15 months after diagnosis. The PRO feedback includes a graphical overview of patients' own symptom and functioning scores and an option to compare their scores with those of other patients with lymphoma and a normative population of the same age and sex. The Living with lymphoma intervention is based on cognitive behavioural therapy components and includes information, assignments, assessments, and videos. Changes in outcomes from baseline to 16 weeks, 12, and 24 months post intervention will be measured. Primary outcomes are self-management skills, satisfaction with information, and psychological distress. Secondary outcomes are health-related quality of life, illness perceptions, fatigue, and health care use. The results of the LIVE trial will provide novel insights into whether access to PRO feedback

Background Based on known or suggested genetic risk factors, a growing number of women now live with knowledge of a potential cancer diagnosis that may never occur. Given this, it is important to understand the meaning of living with high risk for hereditary breast cancer. Objective The objective of the study was to explore how women at high risk for hereditary breast cancer (1) form self-identity, (2) apply self-care strategies toward risk, and (3) describe the meaning of care through a high-risk breast program. Methods Interpretive hermeneutic phenomenology guided the qualitative research method. Women at high risk for hereditary breast cancer were recruited from a high-risk breast program. Open-ended interview questions focused on experiences living as women managing high risk for breast cancer. Consistent with hermeneutic methodology, the principal investigator led a team to analyze the interview transcripts. Results Twenty women participated in in-depth interviews. Analysis revealed that women describe their own identity based on their family story and grieve over actual and potential familial loss. This experience influences self-care strategies, including seeking care from hereditary breast cancer risk experts for early detection and prevention, as well as maintaining a connection for early treatment “when” diagnosis occurs. Conclusions Healthy women living with high risk for hereditary breast cancer are living within the context of their family cancer story, which influences how they define themselves and engage in self-care. Implications for Practice Findings present important practical, research, and policy information regarding health promotion, psychosocial assessment, and support for women living with this risk.

Care for commercial living donors: the experience of an NGO's outreach in Egypt.

Follow-up care for living organ donors is inadequate in countries with advanced transplantation systems based on altruistic donation. In cases where financial incentives drive an organ donation, care for the live 'donor' is largely absent. Care must be provided not only to living altruistic organ donors but especially to victims of organ trafficking who are often not suitable candidates for a donation and subject to poor surgical practices and conditions. Such follow-up is essential not only as a basic right, but also as an important reconciliatory step to regain public trust in transplants where they have been characterized by commercialism. Yet, the question, who will provide care for the commercial living donor? persists. In the absence of public or private commitments to this care, the Coalition for Organ-Failure Solutions (COFS) conducts outreach programmes that include identifying victims of organ trafficking, assessing their consequences and arranging support services. This paper presents studies on consequences for commercial living donors (CLDs), describes the case of organ trafficking and COFS' care provision in Egypt and discusses why follow-up care for CLDs is not an appropriate ingredient for advancing regulation proposals but should be considered an essential component of the movement to end organ trafficking. © 2010 The Authors.

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

The Liminal and the Parallax: Living and Dying at the End of Life.

Transitions to palliative care can involve a shift in philosophy from life-prolonging to life-enhancing care. People living with a life-limiting illness will often receive palliative care through specialist outpatient clinics, while also being cared for by another medical specialty. Experiences of this point of care have been described as being liminal in character, that is, somewhere between living and dying. Drawing on experiences of illness and care taken from semistructured interviews with 30 palliative care outpatients in Australia, we found that this phase was frequently understood as concurrently living and dying. We suggest that this is a "parallax experience" involving narratives of a coherent linear self that is able to understand both realities, in a way that acknowledges the benefits of being multiple. These findings have significant implications for the ways in which palliative care is understood and how the self and subjectivity might be conceptualized at the end of life.

"No future without a past" or "History will teach us nothing"?

.In 1947, Harold Clayton Urey published a landmark paper on the thermodynamic properties of isotopic substances. With his work, Urey paved the way for the reconstruction of paleotemperatures based on small differences in the distribution of stable isotopes in compounds such as sedimentary calcium carbonate. Cesare Emiliani (a student of Urey) followed in Urey's footsteps and in 1955 provided temperature reconstructions over several glacial cycles based on stable isotopes - as Urey had proposed. Emiliani is today considered the father of Paleoceanography. Over the past 60 years, the field has grown immensely and has provided unique and fundamental knowledge about the functioning of the Earth system and Earth's climatic history. In this presentation, I will explain why studying the climate of the past is fun and important. I will make the case that studying past climate events is indispensable to predicting future climate change resulting from human activities ("No future without a past"). If mankind continues on the current path of carbon emissions, atmospheric carbon dioxide concentrations will reach levels probably unprecedented during the past 30 million years. The rate of anthropogenic carbon input is likely unprecedented during the past 56 million years. Recent evidence from paleoclimate archives reveals dramatic and long-lived consequences for Earth's climate and environment following large and rapid carbon release into the ocean-atmosphere system. While the evidence for the close link between rising atmospheric carbon dioxide levels and past climate change is unequivocal, such lessons from the past seem to be largely ignored at the moment ("History will teach us nothing"?). Currently, there is no indication that mankind will start reducing carbon emissions any time soon. In 1973, Emiliani warned: "If the present climatic balance is not maintained, we may soon be confronted with either a runaway glaciation or runaway deglaciation." The past forty years of

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

The Hidden Lives of Nurses' Cognitive Artifacts.

Standardizing nursing handoffs at shift change is recommended to improve communication, with electronic tools as the primary approach. However, nurses continue to rely on personally created paper-based cognitive artifacts - their "paper brains" - to support handoffs, indicating a deficiency in available electronic versions. The purpose of this qualitative study was to develop a deep understanding of nurses' paper-based cognitive artifacts in the context of a cancer specialty hospital. After completing 73 hours of hospital unit field observations, 13 medical oncology nurses were purposively sampled, shadowed for a single shift and interviewed using a semi-structured technique. An interpretive descriptive study design guided analysis of the data corpus of field notes, transcribed interviews, images of nurses' paper-based cognitive artifacts, and analytic memos. Findings suggest nurses' paper brains are personal, dynamic, living objects that undergo a life cycle during each shift and evolve over the course of a nurse's career. The life cycle has four phases: Creation, Application, Reproduction, and Destruction. Evolution in a nurse's individually styled, paper brain is triggered by a change in the nurse's environment that reshapes cognitive needs. If a paper brain no longer provides cognitive support in the new environment, it is modified into (adapted) or abandoned (made extinct) for a different format that will provide the necessary support. The "hidden lives" - the life cycle and evolution - of paper brains have implications for the design of successful electronic tools to support nursing practice, including handoff. Nurses' paper brains provide cognitive support beyond the context of handoff. Information retrieval during handoff is undoubtedly an important function of nurses' paper brains, but tools designed to standardize handoff communication without accounting for cognitive needs during all phases of the paper brain life cycle or the ability to evolve with

Beam-on imaging of short-lived positron emitters during proton therapy

In vivo dose delivery verification in proton therapy can be performed by positron emission tomography (PET) of the positron-emitting nuclei produced by the proton beam in the patient. A PET scanner installed in the treatment position of a proton therapy facility that takes data with the beam on will see very short-lived nuclides as well as longer-lived nuclides. The most important short-lived nuclide for proton therapy is 12N (Dendooven et al 2015 Phys. Med. Biol. 60 8923-47), which has a half-life of 11 ms. The results of a proof-of-principle experiment of beam-on PET imaging of short-lived 12N nuclei are presented. The Philips Digital Photon Counting Module TEK PET system was used, which is based on LYSO scintillators mounted on digital SiPM photosensors. A 90 MeV proton beam from the cyclotron at KVI-CART was used to investigate the energy and time spectra of PET coincidences during beam-on. Events coinciding with proton bunches, such as prompt gamma rays, were removed from the data via an anti-coincidence filter with the cyclotron RF. The resulting energy spectrum allowed good identification of the 511 keV PET counts during beam-on. A method was developed to subtract the long-lived background from the 12N image by introducing a beam-off period into the cyclotron beam time structure. We measured 2D images and 1D profiles of the 12N distribution. A range shift of 5 mm was measured as 6  ±  3 mm using the 12N profile. A larger, more efficient, PET system with a higher data throughput capability will allow beam-on 12N PET imaging of single spots in the distal layer of an irradiation with an increased signal-to-background ratio and thus better accuracy. A simulation shows that a large dual panel scanner, which images a single spot directly after it is delivered, can measure a 5 mm range shift with millimeter accuracy: 5.5  ±  1.1 mm for 1  ×  108 protons and 5.2  ±  0.5 mm for 5  ×  108 protons.

Addiction and will.

PubMed

Johnson, Brian

2013-01-01

A hypothesis about the neurobiological bases of drive, drive reduction and will in addictive illness is presented. Drive reduction seems to require both SEEKING and gratification. Will is the everyday term for our experience of drives functioning within us. Addictive drugs take over the will by altering neurotransmission in the SEEKING system. As a result of this biological change, psychological defenses are arrayed that allow partial gratification and reduce anxiety about the consequences of drug use. Repeated partial gratification of the addictive drive creates a cathexis to the drug and the drug seller. It also keeps the addicted person in a permanent state of SEEKING. The cathexis to the drug and drug seller creates a difficult situation for psychoanalytic therapists. The actively addicted patient will have one set of feelings for the analyst, and a split off set of feelings for the drug dealer. Addictive neuroses, which feature a split transference, are contrasted with Freud's concept of transference and narcissistic neuroses. For treatment of an actively addicted patient, the treater must negotiate the split transference. By analyzing the denial system the relationship with the drug dealer ends and the hostility involved in addictive behavior enters the transference where it can be interpreted. Selling drugs that take over the will is a lucrative enterprise. The addictive drug industry, about the size of the oil and gas industry worldwide, produces many patients in need of treatment. The marketers of addictive drugs understand the psychology of inducing initial ingestion of the drugs, and of managing their addicted populations. The neuropsychoanalytic understanding of addiction might be used to create more effective public health interventions to combat this morbid and mortal illness.

A year later, we value the role of this museum in the film.

Watch Out for the "Living Dead": Cell-Free Enzymes and Their Fate.

PubMed

Baltar, Federico

2017-01-01

Microbes are the engines driving biogeochemical cycles. Microbial extracellular enzymatic activities (EEAs) are the "gatekeepers" of the carbon cycle. The total EEA is the sum of cell-bound (i.e., cell-attached), and dissolved (i.e., cell-free) enzyme activities. Cell-free enzymes make up a substantial proportion (up to 100%) of the total marine EEA. Although we are learning more about how microbial diversity and function (including total EEA) will be affected by environmental changes, little is known about what factors control the importance of the abundant cell-free enzymes. Since cell-attached EEAs are linked to the cell, their fate will likely be linked to the factors controlling the cell's fate. In contrast, cell-free enzymes belong to a kind of "living dead" realm because they are not attached to a living cell but still are able to perform their function away from the cell; and as such, the factors controlling their activity and fate might differ from those affecting cell-attached enzymes. This article aims to place cell-free EEA into the wider context of hydrolysis of organic matter, deal with recent studies assessing what controls the production, activity and lifetime of cell-free EEA, and what their fate might be in response to environmental stressors. This perspective article advocates the need to go "beyond the living things," studying the response of cells/organisms to different stressors, but also to study cell-free enzymes, in order to fully constrain the future and evolution of marine biogeochemical cycles.

Dynamical Signatures of Living Systems

One of the main challenges in modeling living systems is to distinguish a random walk of physical origin (for instance, Brownian motions) from those of biological origin and that will constitute the starting point of the proposed approach. As conjectured, the biological random walk must be nonlinear. Indeed, any stochastic Markov process can be described by linear Fokker-Planck equation (or its discretized version), only that type of process has been observed in the inanimate world. However, all such processes always converge to a stable (ergodic or periodic) state, i.e., to the states of a lower complexity and high entropy. At the same time, the evolution of living systems directed toward a higher level of complexity if complexity is associated with a number of structural variations. The simplest way to mimic such a tendency is to incorporate a nonlinearity into the random walk; then the probability evolution will attain the features of diffusion equation: the formation and dissipation of shock waves initiated by small shallow wave disturbances. As a result, the evolution never "dies:" it produces new different configurations which are accompanied by an increase or decrease of entropy (the decrease takes place during formation of shock waves, the increase-during their dissipation). In other words, the evolution can be directed "against the second law of thermodynamics" by forming patterns outside of equilibrium in the probability space. Due to that, a specie is not locked up in a certain pattern of behavior: it still can perform a variety of motions, and only the statistics of these motions is constrained by this pattern. It should be emphasized that such a "twist" is based upon the concept of reflection, i.e., the existence of the self-image (adopted from psychology). The model consists of a generator of stochastic processes which represents the motor dynamics in the form of nonlinear random walks, and a simulator of the nonlinear version of the diffusion

Bioluminescence imaging is widely used for cell-based assays and animal imaging studies in biomedical research and drug development, capitalizing on the high signal to background of this technique. A relatively small number of luciferases are available for imaging studies, substantially limiting the ability to image multiple molecular and cellular events, as done commonly with fluorescence imaging. To advance dual reporter bioluminescence molecular imaging, we tested a recently developed, adenosine triphosphate–independent luciferase enzyme from Oplophorus gracilirostris (NanoLuc [NL]) as a reporter for animal imaging. We demonstrated that NL could be imaged in superficial and deep tissues in living mice, although the detection of NL in deep tissues was limited by emission of predominantly blue light by this enzyme. Changes in bioluminescence from NL over time could be used to quantify tumor growth, and secreted NL was detectable in small volumes of serum. We combined NL and firefly luciferase reporters to quantify two key steps in transforming growth factor β signaling in intact cells and living mice, establishing a novel dual luciferase imaging strategy for quantifying signal transduction and drug targeting. Our results establish NL as a new reporter for bioluminescence imaging studies in intact cells and living mice that will expand imaging of signal transduction in normal physiology, disease, and drug development.

We examined the meaning of living with HIV/AIDS among women in Lebanon. Ten women living with HIV/AIDS (WLWHA) described their experiences via semistructured in-depth interviews. They navigated a process of HIV diagnosis acceptance that incorporated six overlapping elements: receiving the news, accessing care, starting treatment, navigating disclosure decisions, negotiating stigma, and maintaining stability. Through these elements, we provide a framework for understanding three major themes that were constructed during data analysis: Stand by my side: Decisions of disclosure; Being “sick” and feeling “normal”: Interacting with self, others, and society; and Living day by day: focusing on the present. We contribute to the existing literature by providing a theoretical framework for understanding the process of diagnosis and sero-status acceptance among WLWHA. This was the first study of its kind to examine the meaning of living with HIV/AIDS among women in a Middle Eastern country. PMID:28462340

In the setting of the current social and political climate, the focus on protection of Black lives in America has come to the forefront. We evaluate how health in the Black community should be a paramount concern that can be addressed in three ways: 1. Connecting the medical community to the Black community, empowering patients with knowledge, and diversifying the medical workforce. These three initiatives will help to decrease the health disparities seen in Black health. Copyright © 2018 National Medical Association. Published by Elsevier Inc. All rights reserved.

Living together in biofilms: the microbial cell factory and its biotechnological implications.

PubMed

Berlanga, Mercedes; Guerrero, Ricardo

2016-10-01

In nature, bacteria alternate between two modes of growth: a unicellular life phase, in which the cells are free-swimming (planktonic), and a multicellular life phase, in which the cells are sessile and live in a biofilm, that can be defined as surface-associated microbial heterogeneous structures comprising different populations of microorganisms surrounded by a self-produced matrix that allows their attachment to inert or organic surfaces. While a unicellular life phase allows for bacterial dispersion and the colonization of new environments, biofilms allow sessile cells to live in a coordinated, more permanent manner that favors their proliferation. In this alternating cycle, bacteria accomplish two physiological transitions via differential gene expression: (i) from planktonic cells to sessile cells within a biofilm, and (ii) from sessile to detached, newly planktonic cells. Many of the innate characteristics of biofilm bacteria are of biotechnological interest, such as the synthesis of valuable compounds (e.g., surfactants, ethanol) and the enhancement/processing of certain foods (e.g., table olives). Understanding the ecology of biofilm formation will allow the design of systems that will facilitate making products of interest and improve their yields.

Mauna Loa--history, hazards and risk of living with the world's largest volcano

Mauna Loa on the Island Hawaiʻi is the world’s largest volcano. People residing on its flanks face many hazards that come with living on or near an active volcano, including lava flows, explosive eruptions, volcanic smog, damaging earthquakes, and local tsunami (giant seawaves). The County of Hawaiʻi (Island of Hawaiʻi) is the fastest growing County in the State of Hawaii. Its expanding population and increasing development mean that risk from volcano hazards will continue to grow. U.S. Geological Survey (USGS) scientists at the Hawaiian Volcano Observatory (HVO) closely monitor and study Mauna Loa Volcano to enable timely warning of hazardous activity and help protect lives and property.

Negative Emissions: Where Will the Carbon Come From?

Aines, R. D.; McCoy, S. T.

2017-12-01

The need for energy technologies that remove carbon dioxide from the air grows with each year of delay in acting to address climate change. The most commonly mentioned approach for achieving that, bioenergy with carbon capture and storage (BECCS), today is largely a modeler's concept, not a technology. Thus, in the near term how can we confidently discuss the scale of biomass for energy with a net reduction in CO2 concentrations in the absence of examples? As a first step toward achieving that research objective, this talk frames the likely ways in which net reductions in CO2 concentrations can be achieved from a lifecycle perspective, and the pathways through which biomass can be converted to fuels and materials while removing CO2 from the atmosphere. We will address questions such as: What pathways exist for converting biomass into transportation fuels, electricity, and materials? How can we capture and manage the carbon dioxide emissions from these kinds of activities? And, what are the tradeoffs between pathways? We have conducted preliminary analyses of some of the common biofuel production pathways, such as ethanol from corn with and without carbon capture. These pathways are still uniformly carbon positive, that is to say, they do not achieve the goal of reducing atmospheric CO2, even if they result in lower emissions than do petroleum-based fuels. More advanced pathways appear to have the capacity for minor atmospheric reductions, including those for drop-in replacement transportation fuels and some long-lived materials. Targets and options for improving these technologies to the point that they can, in fact, be carbon negative will be discussed, including pre-processing of the biomass near the production site to reduce transportation emissions, finding ways to manage small CO2 sources associated with processing, and uses of biochar. We will end with a summary of near-term RD&D needs to advance carbon-negative pathways and the associated technologies. This

Background Non‐married persons are known to have poor mental health compared with married persons. Health differences between marital status groups may largely arise from corresponding differences in interpersonal social bonds. However, official marital status mirrors the social reality of persons to a decreasing extent, and living arrangements may be a better measure of social bonds. Little is known about mental health in different living arrangement groups. This study aims to establish the extent and determinants of mental health differences by living arrangement in terms of psychological distress (GHQ) and DSM‐IV psychiatric disorders (CIDI). Methods Data were used from the nationally representative cross sectional health 2000 survey, conducted in 2000–1 in Finland. Altogether 4685 participants (80%) aged 30–64 years were included in these analyses; comprehensive information was available on measures of mental health and living arrangements. Living arrangements were measured as follows: married, cohabiting, living with other(s) than a partner, and living alone. Results Compared with the married, persons living alone and those living with other(s) than a partner were approximately twice as likely to have anxiety or depressive disorders. Cohabiters did not differ from the married. In men, psychological distress was similarly associated with living arrangements. Unemployment, lack of social support, and alcohol consumption attenuated the excess psychological distress and psychiatric morbidity of persons living alone and of those living with other(s) than a partner by about 10%–50% each. Conclusions Living arrangements are strongly associated with mental health, particularly among men. Information on living arrangements, social support, unemployment, and alcohol use may facilitate early stage recognition of poor mental health in primary health care. PMID:16698975

Flow around a Living Tree

Flow around a living tree was investigated as basic research of a windbreak forest. A type of conifer, which is named “goldcrest, ” was used as the test piece in a wind tunnel experiment. The drag coefficient of the living tree was measured in the range of a mean flow velocity of 5˜15m/s. The drag coefficient of the living tree was less than that of a two-dimensional circular cylinder. Because flow passes through the tree’s crown which has the permeability of branches and leaves, the drag coefficient was decreased as the flow velocity was increased. Moreover, the flexibility is that the bole of a living tree also plays an important role in drag reduction, bending itself so as to decrease the projected area. In the wake behind the living tree, reverse flow was found at further downstream region than the case of a circular cylinder.

Addiction and will

PubMed Central

Johnson, Brian

2013-01-01

A hypothesis about the neurobiological bases of drive, drive reduction and will in addictive illness is presented. Drive reduction seems to require both SEEKING and gratification. Will is the everyday term for our experience of drives functioning within us. Addictive drugs take over the will by altering neurotransmission in the SEEKING system. As a result of this biological change, psychological defenses are arrayed that allow partial gratification and reduce anxiety about the consequences of drug use. Repeated partial gratification of the addictive drive creates a cathexis to the drug and the drug seller. It also keeps the addicted person in a permanent state of SEEKING. The cathexis to the drug and drug seller creates a difficult situation for psychoanalytic therapists. The actively addicted patient will have one set of feelings for the analyst, and a split off set of feelings for the drug dealer. Addictive neuroses, which feature a split transference, are contrasted with Freud’s concept of transference and narcissistic neuroses. For treatment of an actively addicted patient, the treater must negotiate the split transference. By analyzing the denial system the relationship with the drug dealer ends and the hostility involved in addictive behavior enters the transference where it can be interpreted. Selling drugs that take over the will is a lucrative enterprise. The addictive drug industry, about the size of the oil and gas industry worldwide, produces many patients in need of treatment. The marketers of addictive drugs understand the psychology of inducing initial ingestion of the drugs, and of managing their addicted populations. The neuropsychoanalytic understanding of addiction might be used to create more effective public health interventions to combat this morbid and mortal illness. PMID:24062657

2015-01-01

Live-donor kidney transplantation (LDKT) is the best treatment for eligible people with late-stage kidney disease. Despite this, living kidney donation rates have declined in the United States in recent years. A potential source of this decline is the financial impact on potential and actual living kidney donors (LKDs). Recent evidence indicates that the economic climate may be associated with the decline in LDKT and that there are nontrivial financial ramifications for some LKDs. In June 2014, the American Society of Transplantation’s Live Donor Community of Practice convened a Consensus Conference on Best Practices in Live Kidney Donation. The conference included transplant professionals, patients, and other key stakeholders (with the financial support of 10 other organizations) and sought to identify best practices, knowledge gaps, and opportunities pertaining to living kidney donation. This workgroup was tasked with exploring systemic and financial barriers to living kidney donation. The workgroup reviewed literature that assessed the financial effect of living kidney donation, analyzed employment and insurance factors, discussed international models for addressing direct and indirect costs faced by LKDs, and summarized current available resources. The workgroup developed the following series of recommendations to reduce financial and systemic barriers and achieve financial neutrality for LKDs: (1) allocate resources for standardized reimbursement of LKDs' lost wages and incidental costs; (2) pass legislation to offer employment and insurability protections to LKDs; (3) create an LKD financial toolkit to provide standardized, vetted education to donors and providers about options to maximize donor coverage and minimize financial effect within the current climate; and (4) promote further research to identify systemic barriers to living donation and LDKT to ensure the creation of mitigation strategies.

Live Storybook Outcomes of pilot multidisciplinary elementary earth science collaborative project Anchoring phenomena leading to student led investigations are key to applying the NGSS standards in the classroom. This project employs the GLOBE elementary storybook, Discoveries at Willow Creek, as an inspiration and operational framework for a collaborative pilot project engaging 4th grade students in asking questions, collecting relevant data, and using analytical tools to document and understand natural phenomena. The Institute of Global Environmental Strategies (IGES), a GLOBE Partner, the Outdoor Campus, an informal educational outdoor learning facility managed by South Dakota Game, Fish and Parks, University of Sioux Falls, and All City Elementary, Sioux Falls are collaborating partners in this project. The Discoveries at Willow Creek storyline introduces young students to the scientific process, and models how they can apply science and engineering practices (SEPs) to discover and understand the Earth system in which they live. One innovation associated with this project is the formal engagement of elementary students in a global citizen science program (for all ages), GLOBE Observer, and engaging them in data collection using GLOBE Observer's Cloud and Mosquito Habitat Mapper apps. As modeled by the fictional students from Willow Creek, the 4th grade students will identify their 3 study sites at the Outdoor Campus, keep a journal, and record observations. The students will repeat their investigations at the Outdoor Campus to document and track change over time. Students will be introduced to "big data" in a manageable way, as they see their observations populate GLOBE's map-based data visualization and . Our research design recognizes the comfort and familiarity factor of literacy activities in the elementary classroom for students and teachers alike, and postulates that connecting a science education project to an engaging storybook text will contribute to a

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

According to the Japanese renal transplant registry in 2009, there were 1123 living kidney transplantations (LKT), including 35% from spouses (husband/wife). Up to the present in Japan, biologically living unrelated donors (LURD) are most frequently spouses. This study summarized our experience with LURD, especially spousal, kidney transplantation. We performed 112 cases of LKT between April 2003 and March 2011, including 44 (39%) from spouses and two from other LURD. The other 66 cases received kidneys from living related donors (LRD). We divided the patients into two groups: 44 patients (group 1) received kidneys from spouses (LURD) and 66 (group 2) from LRD. During the induction phase, tacrolimus or cyclosporine, mycophenolate mofetil, and methylprednisolone were prescribed for immunosuppression. Basiliximab was administered on postoperative days 0 and 4. In ABO-incompatible LKT, plasmapheresis was performed to remove anti-AB antibodies prior to LKT; splenectomy or rituximab administration, at the time of or before LKT. Among group 1, one patient died with a functioning graft and one lost her graft. Among group 2, one patient died with a functioning graft and one lost his graft. The incidences of an acute rejection episode were 31.8% and 24.2% in groups 1 and 2, respectively. There were three cases of antibody-mediated rejection in group 1. No patient experienced a lethal infectious complication. Our results demonstrated that spousal LKT (LURD) was equivalent to LKT from LRD. In response to the shortage of deceased donors, LKT between married couples and from ABO-incompatible donors will spread in Japan. Copyright © 2012 Elsevier Inc. All rights reserved.

Different categories of living and non-living sound-sources activate distinct cortical networks

With regard to hearing perception, it remains unclear as to whether, or the extent to which, different conceptual categories of real-world sounds and related categorical knowledge are differentially represented in the brain. Semantic knowledge representations are reported to include the major divisions of living versus non-living things, plus more specific categories including animals, tools, biological motion, faces, and places—categories typically defined by their characteristic visual features. Here, we used functional magnetic resonance imaging (fMRI) to identify brain regions showing preferential activity to four categories of action sounds, which included non-vocal human and animal actions (living), plus mechanical and environmental sound-producing actions (non-living). The results showed a striking antero-posterior division in cortical representations for sounds produced by living versus non-living sources. Additionally, there were several significant differences by category, depending on whether the task was category-specific (e.g. human or not) versus non-specific (detect end-of-sound). In general, (1) human-produced sounds yielded robust activation in the bilateral posterior superior temporal sulci independent of task. Task demands modulated activation of left-lateralized fronto-parietal regions, bilateral insular cortices, and subcortical regions previously implicated in observation-execution matching, consistent with “embodied” and mirror-neuron network representations subserving recognition. (2) Animal action sounds preferentially activated the bilateral posterior insulae. (3) Mechanical sounds activated the anterior superior temporal gyri and parahippocampal cortices. (4) Environmental sounds preferentially activated dorsal occipital and medial parietal cortices. Overall, this multi-level dissociation of networks for preferentially representing distinct sound-source categories provides novel support for grounded cognition models that may

Long-lived stops in MSSM scenarios with a neutralino LSP

Johansen, M.; Edsjö, J.; Hellman, S.; Milstead, D.

2010-08-01

This work investigates the possibility of a long-lived stop squark in supersymmetric models with the neutralino as the lightest supersymmetric particle (LSP). We study the implications of meta-stable stops on the sparticle mass spectra and the dark matter density. We find that in order to obtain a sufficiently long stop lifetime so as to be observable as a stable R-hadron at an LHC experiment, we need to fine tune the mass degeneracy between the stop and the LSP considerably. This increases the stop-neutralino co-anihilation cross section, leaving the neutralino relic density lower than what is expected from the WMAP results for stop masses ≲1.5 TeV/ c 2. However, if such scenarios are realised in nature we demonstrate that the long-lived stops will be produced at the LHC and that stop-based R-hadrons with masses up to 1 TeV/c2 can be detected after one year of running at design luminosity.

Designed Proteins as Novel Imaging Reagents in Living Escherichia coli.

2016-09-02

Fluorescence imaging is a powerful tool to study protein function in living cells. Here, we introduce a novel imaging strategy that is fully genetically encodable, does not require the use of exogenous substrates, and adds a minimally disruptive tag to the protein of interest (POI). Our method was based on a set of designed tetratricopeptide repeat affinity proteins (TRAPs) that specifically and reversibly interact with a short, extended peptide tag. We co-expressed the TRAPs fused to fluorescent proteins (FPs) and the peptide tags fused to the POIs. We illustrated the method using the Escherichia coli protein FtsZ and showed that our system could track distinct FtsZ structures under both low and high expression conditions in live cells. We anticipate that our imaging strategy will be a useful tool for imaging the subcellular localization of many proteins, especially those recalcitrant to imaging by direct tagging with FPs. © 2016 WILEY-VCH Verlag GmbH & Co.

Children Living with HIV-Infected Adults: Estimates for 23 Countries in sub-Saharan Africa

PubMed Central

Short, Susan E.; Goldberg, Rachel E.

2015-01-01

Background In sub-Saharan Africa many children live in extreme poverty and experience a burden of illness and disease that is disproportionately high. The emergence of HIV and AIDS has only exacerbated long-standing challenges to improving children’s health in the region, with recent cohorts experiencing pediatric AIDS and high levels of orphan status, situations which are monitored globally and receive much policy and research attention. Children’s health, however, can be affected also by living with HIV-infected adults, through associated exposure to infectious diseases and the diversion of household resources away from them. While long recognized, far less research has focused on characterizing this distinct and vulnerable population of HIV-affected children. Methods Using Demographic and Health Survey data from 23 countries collected between 2003 and 2011, we estimate the percentage of children living in a household with at least one HIV-infected adult. We assess overlaps with orphan status and investigate the relationship between children and the adults who are infected in their households. Results The population of children living in a household with at least one HIV-infected adult is substantial where HIV prevalence is high; in Southern Africa, the percentage exceeded 10% in all countries and reached as high as 36%. This population is largely distinct from the orphan population. Among children living in households with tested, HIV-infected adults, most live with parents, often mothers, who are infected; nonetheless, in most countries over 20% live in households with at least one infected adult who is not a parent. Conclusion Until new infections contract significantly, improvements in HIV/AIDS treatment suggest that the population of children living with HIV-infected adults will remain substantial. It is vital to on-going efforts to reduce childhood morbidity and mortality to consider whether current care and outreach sufficiently address the distinct

Molecular nanodevices are computational assemblers that switch defined states upon external stimulation. However, interfacing artificial nanodevices with natural molecular machineries in living cells remains a great challenge. Here, we delineate a generic method for programming assembly of enzyme-initiated DNAzyme nanodevices (DzNanos). Two programs including split assembly of two partzymes and toehold exchange displacement assembly of one intact DNAzyme initiated by telomerase are computed. The intact one obtains higher assembly yield and catalytic performance ascribed to proper conformation folding and active misplaced assembly. By employing MnO 2 nanosheets as both DNA carriers and source of Mn 2+ as DNAzyme cofactor, we find that this DzNano is well assembled via a series of conformational states in living cells and operates autonomously with sustained cleavage activity. Other enzymes can also induce corresponding DzNano assembly with defined programming modules. These DzNanos not only can monitor enzyme catalysis in situ but also will enable the implementation of cellular stages, behaviors, and pathways for basic science, diagnostic, and therapeutic applications as genetic circuits.

Detecting infrared luminescence and non-chemical signaling of living cells: single cell mid-IR spectroscopy in cryogenic environments

NASA Astrophysics Data System (ADS)

Pereverzev, Sergey

2017-02-01

Many life-relevant interaction energies are in IR range, and it is reasonable to believe that some biochemical reactions inside cells can results in emission of IR photons. Cells can use this emission for non-chemical and non-electrical signaling. Detecting weak infrared radiation from live cells is complicated because of strong thermal radiation background and absorption of radiation by tissues. A microfluidic device with live cells inside a vacuum cryogenic environment should suppress this background, and thereby permit observation of live cell auto-luminescence or signaling in the IR regime. One can make IR-transparent windows not emitting in this range, so only the cell and a small amount of liquid around it will emit infrared radiation. Currently mid-IR spectroscopy of single cells requires the use of a synchrotron source to measure absorption or reflection spectra. Decreasing of thermal radiation background will allow absorption and reflection spectroscopy of cells without using synchrotron light. Moreover, cell auto-luminescence can be directly measured. The complete absence of thermal background radiation for cryogenically cooled samples allows the use IR photon-sensitive detectors and obtaining single molecule sensitivity in IR photo-luminescence measurements. Due to low photon energies, photo-luminescence measurements will be non-distractive for pressures samples. The technique described here is based upon US patent 9366574.

Live-donor kidney transplantation (LDKT) is the best treatment for eligible people with late-stage kidney disease. Despite this, living kidney donation rates have declined in the United States in recent years. A potential source of this decline is the financial impact on potential and actual living kidney donors (LKDs). Recent evidence indicates that the economic climate may be associated with the decline in LDKT and that there are nontrivial financial ramifications for some LKDs. In June 2014, the American Society of Transplantation's Live Donor Community of Practice convened a Consensus Conference on Best Practices in Live Kidney Donation. The conference included transplant professionals, patients, and other key stakeholders (with the financial support of 10 other organizations) and sought to identify best practices, knowledge gaps, and opportunities pertaining to living kidney donation. This workgroup was tasked with exploring systemic and financial barriers to living kidney donation. The workgroup reviewed literature that assessed the financial effect of living kidney donation, analyzed employment and insurance factors, discussed international models for addressing direct and indirect costs faced by LKDs, and summarized current available resources. The workgroup developed the following series of recommendations to reduce financial and systemic barriers and achieve financial neutrality for LKDs: (1) allocate resources for standardized reimbursement of LKDs' lost wages and incidental costs; (2) pass legislation to offer employment and insurability protections to LKDs; (3) create an LKD financial toolkit to provide standardized, vetted education to donors and providers about options to maximize donor coverage and minimize financial effect within the current climate; and (4) promote further research to identify systemic barriers to living donation and LDKT to ensure the creation of mitigation strategies.

Ochiai, Hiroshi; Sugawara, Takeshi; Yamamoto, Takashi

2015-01-01

The relationship between genome organization and gene expression has recently been established. However, the relationships between spatial organization, dynamics, and transcriptional regulation of the genome remain unknown. In this study, we developed a live-imaging method for simultaneous measurements of the transcriptional activity and nuclear position of endogenous genes, which we termed the ‘Real-time Observation of Localization and EXpression (ROLEX)’ system. We demonstrated that ROLEX is highly specific and does not affect the expression level of the target gene. ROLEX enabled detection of sub-genome-wide mobility changes that depended on the state of Nanog transactivation in embryonic stem cells. We believe that the ROLEX system will become a powerful tool for exploring the relationship between transcription and nuclear dynamics in living cells. PMID:26092696

Live-cell imaging for the assessment of the dynamics of autophagosome formation: focus on early steps.

PubMed

Karanasios, Eleftherios; Ktistakis, Nicholas T

2015-03-01

Autophagy is a cytosolic degradative pathway, which through a series of complicated membrane rearrangements leads to the formation of a unique double membrane vesicle, the autophagosome. The use of fluorescent proteins has allowed visualizing the autophagosome formation in live cells and in real time, almost 40 years after electron microscopy studies observed these structures for the first time. In the last decade, live-cell imaging has been extensively used to study the dynamics of autophagosome formation in cultured mammalian cells. Hereby we will discuss how the live-cell imaging studies have tried to settle the debate about the origin of the autophagosome membrane and how they have described the way different autophagy proteins coordinate in space and time in order to drive autophagosome formation.

Benzofurazan Sulfides for Thiol Imaging and Quantification in Live Cells through Fluorescence Microscopy

PubMed Central

Li, Yinghong; Yang, Yang; Guan, Xiangming

2012-01-01

Thiol groups play a significant role in various cellular functions. Cellular thiol concentrations can be affected by various physiological or pathological factors. A fluorescence imaging agent that can effectively and specifically image thiols in live cells through fluorescence microscopy is desirable for live cell thiol monitoring. Benzofurazan sulfides 1a–e were synthesized and found to be thiol specific fluorogenic agents except 1d. They are not fluorescent but form strong fluorescent thiol adducts after reacting with thiols through a sulfide-thiol exchange reaction. On the other hand, they exhibit no reaction with other biologically relevant nucleophilic functional groups such as -NH2, -OH, or -COOH revealing the specificity for the detection of thiols. Sulfide 1a was selected to confirm its ability to image cellular thiols through fluorescence microscopy. The compound was demonstrated to effectively image and quantify thiol changes in live cells through fluorescence microscopy using 430 nm and 520 nm as the excitation and emission wavelengths respectively. The quantification results of total thiol in live cells obtained from fluorescence microscopy were validated by an HPLC/UV total thiol assay method. The reagents and method will be of a great value to thiol redox-related research. PMID:22794193

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

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

Solid organ transplantation as a treatment for end stage organ failure has been an accepted treatment option for decades. Despite advances in medicine and technology, and increased awareness of organ donation and transplantation, the gap between supply and demand continues to widen. Living donation has been an option that has increased the number of transplants despite the continued shortage of deceased organs. In the early 2000s live donor transplantation reached an all-time high in the United States. As a result, a consensus meeting was convened in 2000 to increase the oversight of living donor transplantation. Both the Centers for Medicare and Medicaid Services and the United Network for Organ Sharing developed regulations that transplant programs performing live donor transplantation. These regulations and guidelines involve the education, evaluation, informed consent process and living donor follow-up care. Two areas in which had significant changes included the psychosocial and the independent living donor advocate (ILDA) evaluation. The purpose of this paper was to outline the current regulations and guidelines associated with the psychosocial and ILDA evaluation as well as provide further recommendations for the administration of a high quality evaluation of living donors. The goals and timing of the evaluation and education of donors; qualifications of the health care providers performing the evaluation; components of the evaluation; education provided to donors; documentation of the evaluation; participation in the selection committee meeting; post-decline and post-donation care of donors is described. Caveats including the paired donor exchange programs and non-directed and directed donation are also considered.

Paired kidney donations to expand the living donor pool.

PubMed

Ferrari, Paolo; de Klerk, Marry

2009-01-01

The shortage of available deceased donors and the longer kidney transplant waiting lists in many countries around the world have placed greater emphasis on living donation (LD) as a means of meeting demand for transplantation in patients with end-stage kidney disease (ESKD). Increased LD rates are also driven by less invasive approaches to donor nephrectomy and by the excellent long-term results. LD kidney transplant outcomes are equivalent, if not superior, to those from deceased donors, even when donor and recipient are not genetically related, as is the case with spousal donations, the most frequent cohort of LD. Approximately 30% of willing and otherwise appropriate kidney donor/recipient pairs are biologically incompatible and do not proceed to live donor transplantation. In recent years, a number of strategies have been introduced to expand living donation programs beyond the classical direct donation, to overcome immunological barriers of blood group or HLA sensitization of recipients. New strategies in LD include paired kidney exchange (PKE), altruistic donation, altruistic donor chains and list exchange programs. Other alternative programs are desensitization and transplantation across the blood-type barrier. Regular PKE programs operate nationally in The Netherlands and the United Kingdom, or regionally in South Korea, Romania, the United States and Australia. If PKE were performed routinely using 2-way or 3-way PKE and altruistic donor chains, the rate of kidney transplants could increase by between 7% and 10%.

A vast amount of literature exists concerning pharmaceutical adherence in osteoporosis. However, the process of learning to live with osteoporosis over time remains largely unknown. The purpose of this study was to gain a deeper understanding of the continued process of how women learn to live with osteoporosis. Our objective was to explore what characterizes women's experiences of living with osteoporosis during the first year after diagnosis, when patients are prescribed anti-osteoporotic treatment, without having experienced an osteoporotic fracture. Forty-two narrative qualitative interviews were conducted with fifteen recently diagnosed Danish women. A longitudinal design was chosen since this allows an investigation of the perspective over time. The interviews were conducted in the period of March 2011 to August 2012. Data were analyzed using a phenomenological-hermeneutic interpretation of text. No medical records were available for the researchers. All information with the exception of T-score was self-reported. The participants' experiences could be described in two key themes developed through the analysis: 1) "To become influenced by the medical treatment" which consisted of two sub-themes "taking the medication", and "discontinuing the medication". 2) "Daily life with osteoporosis", which was characterized by three sub-themes: "interpretation of symptoms", "interpretation of the scan results" and "lifestyle reflections". The results highlighted that learning to live with osteoporosis is a multifaceted process that is highly influenced by the medical treatment. In some cases, this is a prolonged process that can take around one year. The results suggest a need for improved support for individual women during the complex process of learning to live with osteoporosis. The study adds new knowledge that can be useful for healthcare professionals taking a health-oriented stance when supporting women in self-management of their illness. Further investigations

A long-standing desire in biological and biomedical sciences is to be able to probe cellular chemistry as biological processes are happening inside living cells. Synchrotron radiation-based Fourier transform infrared (SR-FTIR) spectral microscopy is a label-free and nondestructive analytical technique that can provide spatiotemporal distributions and relative abundances of biomolecules of a specimen by their characteristic vibrational modes. Despite great progress in recent years, SR-FTIR imaging of living biological systems remains challenging because of the demanding requirements on environmental control and strong infrared absorption of water. To meet this challenge, microfluidic devices have emerged as a method to control the water thickness while providing a hospitable environment to measure cellular processes and responses over many hours or days. This paper will provide an overview of microfluidic device development for SR-FTIR imaging of living biological systems, provide contrast between the various techniques including closed and open-channel designs, and discuss future directions of development within this area. Even as the fundamental science and technological demonstrations develop, other ongoing issues must be addressed; for example, choosing applications whose experimental requirements closely match device capabilities, and developing strategies to efficiently complete the cycle of development.

Background There are few weight gain prevention interventions aimed at new immigrants. Live Well, a community-based participatory research (CBPR) study, was designed to address this gap. Objective The goal of this paper is to describe the development of the Live Well nutrition and physical activity curriculum. Methods The curriculum draws on behavioral theory and popular education and was co-created, implemented, and will be evaluated by community partners and academic researchers. Results The time it took to develop the curriculum exceeded initial estimates. However, the extra time taken was spent engaging in needed dialogue to create a better product, fully co-created by academic and community partners. Additionally, working with an outside expert created the opportunity for all partners to train together, build capacity, and increase cohesion. Our approach developed relationships and trust, and resulted in a unique curriculum. Conclusions The commitment to partnership resulted in a curriculum to empower immigrant women to improve health decisions and behaviors. This will inform future research and programming targeting other at-risk and new immigrant communities. PMID:22820229

On harm thresholds and living organ donation: must the living donor benefit, on balance, from his donation?

PubMed

Williams, Nicola Jane

2018-03-01

For the majority of scholars concerned with the ethics of living organ donation, inflicting moderate harms on competent volunteers in order to save the lives or increase the life chances of others is held to be justifiable provided certain conditions are met. These conditions tend to include one, or more commonly, some combination of the following: (1) The living donor provides valid consent to donation. (2) Living donation produces an overall positive balance of harm-benefit for donors and recipients which cannot be obtained in a less harmful manner. (3) Donation is not liable to cause significant and long-term morbidity to, or the death of, the donor. This paper critically examines the suggestion that these criteria are not sufficient to offer a general account of justified living organ donation in the context of competent volunteers and that key to justified living organ donation is that donors receive sufficient benefits from their donation that these outweigh the harms they suffer. However, although this view-termed here 'The Donor Benefit Standard'-directs welcome attention to the many and complex motives which may underlie living organ donation, this paper ultimately concludes that given the threats this position poses to individual autonomy and the lives of those in need of organ transplants 'The Donor Benefit Standard' should ultimately be rejected.

There exists a conspicuous gap of knowledge about the organization of life at mesoscopic levels. Ultra-fast coherent diffractive imaging with X-ray free-electron lasers can probe structures at the relevant length scales and may reach sub-nanometer resolution on micron-sized living cells. Here we show that we can introduce a beam of aerosolised cyanobacteria into the focus of the Linac Coherent Light Source and record diffraction patterns from individual living cells at very low noise levels and at high hit ratios. We obtain two-dimensional projection images directly from the diffraction patterns, and present the results as synthetic X-ray Nomarski images calculated from the complex-valued reconstructions. We further demonstrate that it is possible to record diffraction data to nanometer resolution on live cells with X-ray lasers. Extension to sub-nanometer resolution is within reach, although improvements in pulse parameters and X-ray area detectors will be necessary to unlock this potential.

Development of low level 226Ra analysis for live fish using gamma-ray spectrometry

NASA Astrophysics Data System (ADS)

Chandani, Z.; Prestwich, W. V.; Byun, S. H.

2017-06-01

A low level 226Ra analysis method for live fish was developed using a 4π NaI(Tl) gamma-ray spectrometer. In order to find out the best algorithm for accomplishing the lowest detection limit, the gamma-ray spectrum from a 226Ra point was collected and nine different methods were attempted for spectral analysis. The lowest detection limit of 0.99 Bq for an hour counting occurred when the spectrum was integrated in the energy region of 50-2520 keV. To extend 226Ra analysis to live fish, a Monte Carlo simulation model with a cylindrical fish in a water container was built using the MCNP code. From simulation results, the spatial distribution of the efficiency and the efficiency correction factor for the live fish model were determined. The MCNP model will be able to be conveniently modified when a different fish or container geometry is employed as fish grow up in real experiments.

Abstract Donor safety is the major concern in living donor liver transplantation, although hepatic resection may be associated with postoperative coagulopathy. Recently, the use of sugammadex has been gradually increased, but sugammadex is known to prolong prothrombin time (PT) and activated partial thromboplastin time (aPTT). We compared the postoperative coagulation profiles and outcomes of sugammadex versus pyridostigmine group in donors receiving living donor hepatectomy. Consecutive donor hepatectomy performed between September 2013 and August 2016 was retrospectively analyzed. For reversal of rocuronium-induced neuromuscular blockade, donors received sugammadex 4 mg/kg or pyridostigmine 0.25 mg/kg. The primary end-points were laboratory findings (PT, aPTT, hemoglobin, platelet count) and clinically evaluated postoperative bleeding (relaparotomy for bleeding, cumulative volume collected in drains). Secondary outcomes were anesthesia time, postoperative hospital day. Of 992 donors, 383 treated with sugammadex and 609 treated with pyridostigmine for the reversal of neuromuscular blockade. There were no significant differences between both groups for drop in hemoglobin and platelet, prolongation in PT, aPTT, and the amount of 24-h drain volume. Bleeding events within 24 h were reported in 2 (0.3%) for pyridostigmine group and 0 (0%) for sugammadex group (P = .262). Anesthesia time was significantly longer in pyridostigmine group than that in sugammadex group (438.8 ± 71.4 vs. 421.3 ± 62.3, P < .001). Postoperative hospital stay was significantly longer in pyridostigmine group than that in sugammadex group (P = .002). Sugammadex 4 mg/kg was not associated with increased bleeding tendency, but associated with reduced anesthesia time and hospital stay. Therefore, sugammadex may be safely used and will decrease morbidity in donor undergoing living-donor hepatectomy. PMID:29538210

Donor safety is the major concern in living donor liver transplantation, although hepatic resection may be associated with postoperative coagulopathy. Recently, the use of sugammadex has been gradually increased, but sugammadex is known to prolong prothrombin time (PT) and activated partial thromboplastin time (aPTT). We compared the postoperative coagulation profiles and outcomes of sugammadex versus pyridostigmine group in donors receiving living donor hepatectomy.Consecutive donor hepatectomy performed between September 2013 and August 2016 was retrospectively analyzed. For reversal of rocuronium-induced neuromuscular blockade, donors received sugammadex 4 mg/kg or pyridostigmine 0.25 mg/kg. The primary end-points were laboratory findings (PT, aPTT, hemoglobin, platelet count) and clinically evaluated postoperative bleeding (relaparotomy for bleeding, cumulative volume collected in drains). Secondary outcomes were anesthesia time, postoperative hospital day.Of 992 donors, 383 treated with sugammadex and 609 treated with pyridostigmine for the reversal of neuromuscular blockade. There were no significant differences between both groups for drop in hemoglobin and platelet, prolongation in PT, aPTT, and the amount of 24-h drain volume. Bleeding events within 24 h were reported in 2 (0.3%) for pyridostigmine group and 0 (0%) for sugammadex group (P = .262). Anesthesia time was significantly longer in pyridostigmine group than that in sugammadex group (438.8 ± 71.4 vs. 421.3 ± 62.3, P < .001). Postoperative hospital stay was significantly longer in pyridostigmine group than that in sugammadex group (P = .002).Sugammadex 4 mg/kg was not associated with increased bleeding tendency, but associated with reduced anesthesia time and hospital stay. Therefore, sugammadex may be safely used and will decrease morbidity in donor undergoing living-donor hepatectomy.

"Living theatre, theatre of life".

Wenzel, E

Young people love to play theatre--in one way or another. They like to play with behaviours, costumes, words, communication patterns, etc.; they like to disguise themselves, to create certain spheres and scenes of drama and tragedy, excitement and extacy, satire and irony, morals and decadence. Due to the particular uncertainties of the adolescent passage, youth oscillates between taking life both, too seriously and easy. Searching for identity and integration, they tend to experiment with styles of behaviour and culturally defined patterns of lifestyles conductive to well-being. Sometimes, life is perceived as pure entertainment, and sometimes as pure drama. It's living theatre and theatre of life. On the one hand it is "acting out", on the other hand it is playing precisely defined roles. And, in-between, it is always the question: Who am I? They tend to slip into roles in order to check out whether they are willing to accept their implications with regard to the priorities they have set so far.

Mechano-biochemical wear encompasses the tribological interplay between biological and mechanical mechanisms responsible for cartilage wear and degradation. The aim of this study was to develop and start validating a novel tribological testing system, which better resembles the natural joint environment through incorporating a live cartilage-on-cartilage articulating interface, joint specific kinematics, and the application of controlled mechanical stimuli for the measurement of biological responses in order to study the mechano-biochemical wear of cartilage. The study entailed two parts. In Part 1, the novel testing rig was used to compare two bearing systems: (a) cartilage articulating against cartilage (CoC) and (b) metal articulating against cartilage (MoC). The clinically relevant MoC, which is also a common tribological interface for evaluating cartilage wear, should produce more wear to agree with clinical observations. In Part II, the novel testing system was used to determine how wear is affected by tissue viability in live and dead CoC articulations. For both parts, bovine cartilage explants were harvested and tribologically tested for three consecutive days. Wear was defined as release of glycosaminoglycans into the media and as evaluation of the tissue structure. For Part I, we found that the live CoC articulation did not cause damage to the cartilage, to the extent of being comparable to the free swelling controls, whereas the MoC articulation caused decreased cell viability, extracellular matrix disruption, and increased wear when compared to CoC, and consistent with clinical data. These results provided confidence that this novel testing system will be adequate to screen new biomaterials for articulation against cartilage, such as in hemiarthroplasty. For Part II, the live and dead cartilage articulation yielded similar wear as determined by the release of proteoglycans and aggrecan fragments, suggesting that keeping the cartilage alive may not be

Watch Out for the “Living Dead”: Cell-Free Enzymes and Their Fate

PubMed Central

Baltar, Federico

2018-01-01

Microbes are the engines driving biogeochemical cycles. Microbial extracellular enzymatic activities (EEAs) are the “gatekeepers” of the carbon cycle. The total EEA is the sum of cell-bound (i.e., cell-attached), and dissolved (i.e., cell-free) enzyme activities. Cell-free enzymes make up a substantial proportion (up to 100%) of the total marine EEA. Although we are learning more about how microbial diversity and function (including total EEA) will be affected by environmental changes, little is known about what factors control the importance of the abundant cell-free enzymes. Since cell-attached EEAs are linked to the cell, their fate will likely be linked to the factors controlling the cell’s fate. In contrast, cell-free enzymes belong to a kind of “living dead” realm because they are not attached to a living cell but still are able to perform their function away from the cell; and as such, the factors controlling their activity and fate might differ from those affecting cell-attached enzymes. This article aims to place cell-free EEA into the wider context of hydrolysis of organic matter, deal with recent studies assessing what controls the production, activity and lifetime of cell-free EEA, and what their fate might be in response to environmental stressors. This perspective article advocates the need to go “beyond the living things,” studying the response of cells/organisms to different stressors, but also to study cell-free enzymes, in order to fully constrain the future and evolution of marine biogeochemical cycles.

Traditionally shellfish hatcheries produce live microalgal cultures to feed larvae. This process is time consuming, labor intensive, expensive, and requires a large and sterile environment. The use of commercial microalgal concentrates allows hatcheries to reduce operational costs and optimize floor space; however, there have been no systematic studies examining the relative yields from live algal vs. concentrate-based diets. The effects of diet type on the growth-rate, survival, and settling efficiency of Crassostrea virginica were explored by varying diet proportions in two-day old spawned larvae through metamorphosis and settlement. Live microalgal feed was blended from axenic Isochrysis, Tetraselmis, Pavlova, and Chaetoceros cultures to mimic typical hatchery recipes. The live microalgae was supplemented with variable amounts of the concentrate, Reed Mariculture Shellfish Diet 1800™, across multiple treatments ranging from 100% concentrate vs. 100% live diet. Caloric content was used to normalize between the diet types to achieve treatments with 25, 50 and 75% live diet supplemented with proportional amounts of concentrate (e.g. 75, 50, and 25% concentrate, respectively). The goal of this method was to show whether survival and settling rates depend on the proportion of live microalgal diet. Such data will inform a cost-benefit analysis of whether concentrates are a financially viable alternative for oyster hatcheries.

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

Three-Dimensional, Live-Cell Imaging of Chromatin Dynamics in Plant Nuclei Using Chromatin Tagging Systems.

PubMed

Hirakawa, Takeshi; Matsunaga, Sachihiro

2016-01-01

In plants, chromatin dynamics spatiotemporally change in response to various environmental stimuli. However, little is known about chromatin dynamics in the nuclei of plants. Here, we introduce a three-dimensional, live-cell imaging method that can monitor chromatin dynamics in nuclei via a chromatin tagging system that can visualize specific genomic loci in living plant cells. The chromatin tagging system is based on a bacterial operator/repressor system in which the repressor is fused to fluorescent proteins. A recent refinement of promoters for the system solved the problem of gene silencing and abnormal pairing frequencies between operators. Using this system, we can detect the spatiotemporal dynamics of two homologous loci as two fluorescent signals within a nucleus and monitor the distance between homologous loci. These live-cell imaging methods will provide new insights into genome organization, development processes, and subnuclear responses to environmental stimuli in plants.

Lived Religion as Reproductive Decision-Making Resource Among Romanian Women Who Use Abortion as Contraception.

PubMed

Pop, Cristina A

2017-05-30

This article draws upon qualitative ethnographic data collected between 2005 and 2013 in southern Romania among women who have been consistently using abortion as a contraceptive method. It particularly considers the role that lived religion might have played in some individuals' strategies to render abortion a justifiable practice. Over the last seven decades, Romanian women's experiences of abortion have often been at odds with both secular and religious regulations. This study shifts the perspective from the biopolitics and the bioethics of abortion toward women's own reproductive decision-making strategies in a context of enduring traditional patriarchy. It explores the fluid and pragmatic ways in which some Romanians use the notions of "God's will," "sin," "redemption," "afterlife," and "Godparenting" to redefine abortion as a partially disembodied reproductive event. As a reproductive decision-making resource, lived religion empowers women to navigate the lived complexities of conception and contraception.

The Living Systems Energy Module, renamed Voyage from the Sun, is a twenty-lesson curriculum designed to introduce students to the major ways in which energy is important in living systems. Voyage from the Sun tells the story of energy, describing its solar origins, how it is incorporated into living terrestrial systems through photosynthesis, how it flows from plants to herbivorous animals, and from herbivores to carnivores. A significant part of the unit is devoted to examining how humans use energy, and how human impact on natural habitats affects ecosystems. As students proceed through the unit, they read chapters of Voyagemore » from the Sun, a comic book that describes the flow of energy in story form (Appendix A). During the course of the unit, an ``Energy Pyramid`` is erected in the classroom. This three-dimensional structure serves as a classroom exhibit, reminding students daily of the importance of energy and of the fragile nature of our living planet. Interactive activities teach students about adaptations that allow plants and animals to acquire, to use and to conserve energy.

Will Moores law be sufficient?

DeBenedictis, Erik P.

2004-07-01

It seems well understood that supercomputer simulation is an enabler for scientific discoveries, weapons, and other activities of value to society. It also seems widely believed that Moore's Law will make progressively more powerful supercomputers over time and thus enable more of these contributions. This paper seeks to add detail to these arguments, revealing them to be generally correct but not a smooth and effortless progression. This paper will review some key problems that can be solved with supercomputer simulation, showing that more powerful supercomputers will be useful up to a very high yet finite limit of around 1021 FLOPSmore » (1 Zettaflops) . The review will also show the basic nature of these extreme problems. This paper will review work by others showing that the theoretical maximum supercomputer power is very high indeed, but will explain how a straightforward extrapolation of Moore's Law will lead to technological maturity in a few decades. The power of a supercomputer at the maturity of Moore's Law will be very high by today's standards at 1016-1019 FLOPS (100 Petaflops to 10 Exaflops), depending on architecture, but distinctly below the level required for the most ambitious applications. Having established that Moore's Law will not be that last word in supercomputing, this paper will explore the nearer term issue of what a supercomputer will look like at maturity of Moore's Law. Our approach will quantify the maximum performance as permitted by the laws of physics for extension of current technology and then find a design that approaches this limit closely. We study a 'multi-architecture' for supercomputers that combines a microprocessor with other 'advanced' concepts and find it can reach the limits as well. This approach should be quite viable in the future because the microprocessor would provide compatibility with existing codes and programming styles while the 'advanced' features would provide a boost to the limits of performance.« less

We describe the development of the Genotype and Phenotype (GaP) Registry, a living biobank of normal volunteers who are genotyped for genetic markers related to human disease. Participants in the GaP can be recalled for hypothesis driven study of disease associated genetic variants. The GaP has facilitated functional studies of several autoimmune disease associated loci including Csk, Blk, PDRM1 (Blimp-1) and PTPN22. It is likely that expansion of such living biobank registries will play an important role in studying and understanding the function of disease associated alleles in complex disease.

We reviewed the history, volume, outcomes, uniqueness, and challenges of living donor liver transplantation (LDLT) in Latin America. We used the data from the Latin American and Caribbean Transplant Society, local transplant societies, and opinions from local transplant experts. There are more than 160 active liver transplant teams in Latin America, but only 30 centers have used LDLT in the past 2 years. In 2014, 226 LDLTs were done in the region (8.5% of liver transplant activities). Living donor liver transplantation is mainly restricted to pediatric patients. Adult-to-adult LDLT activities decreased after the implementation of the model for end-stage liver disease score and a concomitant increase on the rate of deceased donors per million population. Posttransplant outcome analysis is not mandatory, transparent or regulated in most countries. More experienced teams have outcomes comparable to international expert centers, but donor and recipient morbidity might be underreported. Latin America lags behind in terms of the number of adult LDLT and the rate of living donor utilization in comparison with other continents with similar donation rates. Local alliances and collaborations with major transplant centers in the developed world will contribute to the development of LDLT in Latin America.

Some living kidney donors report lost income during recovery from surgery. Little is known about whether concern for living donor's lost income affects the decision to undergo donation evaluation and the willingness of transplant candidates to discuss living kidney donation (LKD) with others. To examine whether transplant patients were told by potential donors about lost income concerns and whether patients chose not to discuss LKD with others due to lost income concerns. Kidney transplant patients (185 wait-listed candidates, 171 deceased donor recipients, and 100 live donor recipients) at 2 centers completed a questionnaire to assess whether concern about donor's lost income was a consideration in discussion about LKD with others. One-third (32%) were told by a family member/friend that they were willing to donate but were concerned about potential lost income. The majority of those who expressed financial concern (64%) did not initiate donation evaluation. Many patients (42%) chose not to discuss living donation with a family member/friend due to concern about the impact of lost income on the donor. In the multivariable model, lower annual household income was the only statistically significant predictor of both having a potential donor expressing lost income concern and choosing not to talk to someone because of lost income concern. Findings from the current study underscore how concern about income loss for living donors may affect decision-making by both transplant candidates and potential donors.

Live-Cell Imaging of Filoviruses.

Observation of molecular processes inside living cells is fundamental to a deeper understanding of virus-host interactions in filoviral-infected cells. These observations can provide spatiotemporal insights into protein synthesis, protein-protein interaction dynamics, and transport processes of these highly pathogenic viruses. Thus, live-cell imaging provides the possibility for antiviral screening in real time and gives mechanistic insights into understanding filovirus assembly steps that are dependent on cellular factors, which then represent potential targets against this highly fatal disease. Here we describe analysis of living filovirus-infected cells under maximum biosafety (i.e., BSL4) conditions using plasmid-driven expression of fluorescently labeled viral and cellular proteins and/or viral genome-encoded expression of fluorescently labeled proteins. Such multiple-color and multidimensional time-lapse live-cell imaging analyses are a powerful method to gain a better understanding of the filovirus infection cycle.

Patients’ experiences of support for learning to live with diabetes to promote health and well-being: A lifeworld phenomenological study

Learning to live with diabetes in such a way that the new conditions will be a normal and natural part of life imposes requirements on the person living with diabetes. Previous studies have shown that there is no clear picture of what and how the learning that would allow persons to incorporate the illness into their everyday life will be supported. The aim of this study is to describe the phenomenon of support for learning to live with diabetes to promote health and well-being, from the patient’s perspective. Data were collected by interviews with patients living with type 1 or type 2 diabetes. The interviews were analysed using a reflective lifeworld approach. The results show that reflection plays a central role for patients with diabetes in achieving a new understanding of the health process, and awareness of their own responsibility was found to be the key factor for such a reflection. The constituents are responsibility creating curiosity and willpower, openness enabling support, technology verifying bodily feelings, a permissive climate providing for participation and exchanging experiences with others. The study concludes that the challenge for caregivers is to create interactions in an open learning climate that initiates and supports reflection to promote health and well-being. PMID:27539956

Free will and paranormal beliefs

Free will is one of the fundamental aspects of human cognition. In the context of cognitive neuroscience, various experiments on time perception, sensorimotor coordination, and agency suggest the possibility that it is a robust illusion (a feeling independent of actual causal relationship with actions) constructed by neural mechanisms. Humans are known to suffer from various cognitive biases and failures, and the sense of free will might be one of them. Here I report a positive correlation between the belief in free will and paranormal beliefs (UFO, reincarnation, astrology, and psi). Web questionnaires involving 2076 subjects (978 males, 1087 females, and 11 other genders) were conducted, which revealed significant positive correlations between belief in free will (theory and practice) and paranormal beliefs. There was no significant correlation between belief in free will and knowledge in paranormal phenomena. Paranormal belief scores for females were significantly higher than those for males, with corresponding significant (albeit weaker) difference in belief in free will. These results are consistent with the view that free will is an illusion which shares common cognitive elements with paranormal beliefs. PMID:24765084

2011-01-01

This article presents a synthesis of what is known about the educational experiences of youth living in residential group care based on a literature review that highlights both the experiences of the youth themselves and the operational context of residential group care in Ontario as it pertains to educational performance. The author argues that there is little emphasis on education within the residential group care sector in Ontario that could translate into more productive educational experiences for youth. The article then provides a framework for developing a culture of education for residential group care that can be acted upon expeditiously. Enhancing the educational performance of young people living in group care will require a cultural approach that provides for daily and pervasive education supports and encouragement, and aims to enhance the lived experience of young people pursuant to their education.

Background: Suicide is a significant public health concern, which impacts on health outcomes. Few suicide research studies have been interdisciplinary. We combined a psychobiographical autopsy with a visual arts autopsy, in which families donated stories, images and objects associated with the lived life of a loved one lost to suicide. From this interdisciplinary research platform, a mediated exhibition was created ( Lived Lives ) with artist, scientist and families, co-curated by communities, facilitating dialogue, response and public action around suicide prevention. Indigenous ethnic minorities (IEMs) bear a significant increased risk for suicide. Irish Travellers are an IEM with social and cultural parallels with IEMs internationally, experiencing racism, discrimination, and poor health outcomes including elevated suicide rates (SMR 6.6). Methods: An adjusted Lived Lives exhibition, Lived Lives: A Pavee Perspective manifested in Pavee Point, the national Traveller and Roma Centre. The project was evaluated by the Travelling Community as to how it related to suicide in their community, how it has shaped their understanding of suicide and its impacts, and its relevance to other socio-cultural contexts, nationally and internationally. The project also obtained feedback from all relevant stakeholders. Evaluation was carried out by an international visual arts research advisor and an independent observer from the field of suicide research. Results: Outputs included an arts-science mediated exhibition with reference to elevated Irish Traveller suicide rates.

We end with a brief look at the social and ethical questions generated by the prospect of living technology.

The third dimension bridges the gap between cell culture and live tissue.

Moving from cell monolayers to three-dimensional (3D) cultures is motivated by the need to work with cellular models that mimic the functions of living tissues. Essential cellular functions that are present in tissues are missed by 'petri dish'-based cell cultures. This limits their potential to predict the cellular responses of real organisms. However, establishing 3D cultures as a mainstream approach requires the development of standard protocols, new cell lines and quantitative analysis methods, which include well-suited three-dimensional imaging techniques. We believe that 3D cultures will have a strong impact on drug screening and will also decrease the use of laboratory animals, for example, in the context of toxicity assays.

Many second-line treatments for advanced non-small-cell lung cancer (NSCLC) have been assessed in randomised controlled trials, but which treatments work the best remains unclear. Novel treatments are being rapidly developed. We need a comprehensive up-to-date evidence synthesis of all these treatments. We present the protocol for a live cumulative network meta-analysis (NMA) to address this need. We will consider trials of second-line treatments in patients with advanced NSCLC with wild-type or unknown epidermal growth factor receptor status. We will consider any single agent of cytotoxic chemotherapy, targeted therapy, combination of cytotoxic chemotherapy and targeted therapy and any combination of targeted therapies. The primary outcomes will be overall survival and progression-free survival. The live cumulative NMA will be initiated with a NMA and then iterations will be repeated at regular intervals to keep the NMA up-to-date over time. We have defined the update frequency as 4 months, based on an assessment of the pace of evidence production on this topic. Each iteration will consist of six methodological steps: adaptive search for treatments and trials, screening of reports and selection of trials, data extraction, assessment of risk of bias, update of the network of trials and synthesis, and dissemination. We will set up a research community in lung cancer, with different groups of contributors of different skills. We will distribute tasks through online crowdsourcing. This proof-of-concept study in second-line treatments of advanced NSCLC will allow one for assessing the feasibility of live cumulative NMA and opening the path for this new form of synthesis. Ethical approval is not required because our study will not include confidential participant data and interventions. The description of all the steps and the results of this live cumulative NMA will be available online. CRD42015017592. Published by the BMJ Publishing Group Limited. For permission to

Psychosocial evaluation is an important part of the live organ donor evaluation process, yet it is not standardized across institutions, and although tools exist for the psychosocial evaluation of organ recipients, none exist to assess donors. We set out to develop a semistructured psychosocial evaluation tool (the Live Donor Assessment Tool, LDAT) to assess potential live organ donors and to conduct preliminary analyses of the tool's reliability and validity. Review of the literature on the psychosocial variables associated with treatment adherence, quality of life, live organ donation outcome, and resilience, as well as review of the procedures for psychosocial evaluation at our center and other centers around the country, identified 9 domains to address; these domains were distilled into several items each, in collaboration with colleagues at transplant centers across the country, for a total of 29 items. Four raters were trained to use the LDAT, and they retrospectively scored 99 psychosocial evaluations conducted on live organ donor candidates. Reliability of the LDAT was assessed by calculating the internal consistency of the items in the scale and interrater reliability between raters; validity was estimated by comparing LDAT scores between those with a "positive" evaluation outcome and "negative" outcome. The LDAT was found to have good internal consistency, inter-rater reliability, and showed signs of validity: LDAT scores differentiated the positive vs. negative outcome groups. The LDAT demonstrated good reliability and validity, but future research on the LDAT and the ability to implement the LDAT prospectively is warranted.

Common challenges and experiences of the lived experience/peer workforce globally are considered, with an emphasis on ensuring that future developments both protect and promote the unique lived experience perspective. In the Western world, rapid growth in lived experience roles has led to an urgent need for training and workforce development. However, research indicates the roles risk being coopted without clear lived experience leadership, which is often not occurring. In developing countries and in many Western contexts, the lived experience role has not yet been accepted within the mental health workforce. The need for lived experience leadership to guide these issues is highlighted. Peer-reviewed research, relevant gray literature, and professional experience in countries where little published material currently exists. A window of opportunity currently exists to maximize lived experience leadership, and that window may be closing fast if broad-based actions are not initiated now.

Hidden impacts of ocean acidification to live and dead coral framework.

Cold-water corals, such as Lophelia pertusa, are key habitat-forming organisms found throughout the world's oceans to 3000 m deep. The complex three-dimensional framework made by these vulnerable marine ecosystems support high biodiversity and commercially important species. Given their importance, a key question is how both the living and the dead framework will fare under projected climate change. Here, we demonstrate that over 12 months L. pertusa can physiologically acclimate to increased CO2, showing sustained net calcification. However, their new skeletal structure changes and exhibits decreased crystallographic and molecular-scale bonding organization. Although physiological acclimatization was evident, we also demonstrate that there is a negative correlation between increasing CO2 levels and breaking strength of exposed framework (approx. 20-30% weaker after 12 months), meaning the exposed bases of reefs will be less effective 'load-bearers', and will become more susceptible to bioerosion and mechanical damage by 2100. © 2015 The Authors.

Sleep, biological stress, and health among toddlers living in socioeconomically disadvantaged homes: A research protocol.

Healthy sleep is important to behavioral, neurobiological, and physiologic health. In older children and adults, stress biomarkers, such as cortisol and C-reactive protein, increase when they do not practice healthy sleep habits. However, little is known about the relationships among sleep health, stress, and health outcomes among very young children living with socioeconomic adversity, a group that is particularly at risk for poor future health. The NIH-funded study described in this protocol addresses this scientific gap to improve understanding of these relationships during a critical developmental period in children's lives-toddlerhood. We will use a longitudinal design with repeated measures to prospectively examine the relationships among sleep health, stress, and toddlers' health from age 12 to 24 months, to address the following aims: i) examine changes in subjective and objective sleep health measures; ii) examine changes in stress biomarkers; iii) examine the cross-sectional and longitudinal relationships between sleep health measures and stress response; and iv) examine the cross-sectional and longitudinal relationships between sleep health measures, stress biomarkers, and toddlers' behavioral health. The sample will include 113 toddlers and their caregivers. We are collecting subjective and objective data on sleep health, multi-systemic biomarkers of stress, and toddlers' behavioral health. Generalized linear models will be used in the data analyses. Results from this study will be used to support development and testing of interventions, such as those that may improve sleep, among young children at risk for toxic stress. © 2017 Wiley Periodicals, Inc.

Population Pressure, Global Living Standards, and the Promise of Space Solar Power

What many sincere environmentalists advocate: (severe restrictions on energy use, to reduce global warming), may actually end up being very harmful to the environment. Since 85 percent of the global energy use is derived from carbon based fossil fuels, this may seem to be a reasonable position. However, the proponents of energy use restrictions are ignoring some very important relationships. The greatest damage to the environment, in terms of species loss, is loss and/or human modification of habitat. The two greatest threats to habitat seem to be (1) population pressure and (2) logging. Logging does not necessarily permanently occupy the land, while either default squatter occupation or "colonization by policy" is often permanent. Increased population degrades the land by causing over- farming, and also creates an ever greater demand for raw materials and food resources. Poor people have no time nor money to think about or help save the environment. Therefore the greatest threat to species survival is human population growth and its frequent companion: poverty. There is an existing way to reduce population growth, and thus to reduce pressure on habitats, called "raising the standard of living". Wherever it succeeds, population growth slows rapidly. In many European countries, there would be a negative population growth if not for immigration. Personal energy use is closely correlated with living standards, and it is impossible to have a higher living standard without a higher degree of personal energy use. It would seem, however, that extending high living standards to the developing world would create an even greater demand for the use of fossil fuels. The solution to this dilemma can only be found in the use of very high capacity sources of non- fossil energy that do not significantly damage the environment. Are there sources of clean, economical energy with a large enough combined capacity to provide high living standards for the whole world, including those

Multi-scale Modeling of Chromosomal DNA in Living Cells

Spakowitz, Andrew

The organization and dynamics of chromosomal DNA play a pivotal role in a range of biological processes, including gene regulation, homologous recombination, replication, and segregation. Establishing a quantitative theoretical model of DNA organization and dynamics would be valuable in bridging the gap between the molecular-level packaging of DNA and genome-scale chromosomal processes. Our research group utilizes analytical theory and computational modeling to establish a predictive theoretical model of chromosomal organization and dynamics. In this talk, I will discuss our efforts to develop multi-scale polymer models of chromosomal DNA that are both sufficiently detailed to address specific protein-DNA interactions while capturing experimentally relevant time and length scales. I will demonstrate how these modeling efforts are capable of quantitatively capturing aspects of behavior of chromosomal DNA in both prokaryotic and eukaryotic cells. This talk will illustrate that capturing dynamical behavior of chromosomal DNA at various length scales necessitates a range of theoretical treatments that accommodate the critical physical contributions that are relevant to in vivo behavior at these disparate length and time scales.

Live coral repels a common reef fish ectoparasite

2013-06-01

Coral reefs are undergoing rapid changes as living corals give way to dead coral on which other benthic organisms grow. This decline in live coral could influence habitat availability for fish parasites with benthic life stages. Gnathiid isopod larvae live in the substratum and are common blood-feeding parasites of reef fishes. We examined substrate associations and preferences of a common Caribbean gnathiid, Gnathia marleyi. Emergence traps set over predominantly live coral substrata captured significantly fewer gnathiids than traps set over dead coral substrata. In laboratory experiments, gnathiids preferred dead coral and sponge and tended to avoid contact with live coral. When live gnathiids were added to containers with dead or live coral, significantly fewer were recovered from the latter after 24 h. Our data therefore suggest that live coral is not suitable microhabitat for parasitic gnathiid isopods and that a decrease in live coral cover increases available habitat for gnathiids.

When Opportunity Knocks Twice: Dual Living Kidney Donation, Autonomy and the Public Interest

PubMed Central

Huxtable, Richard

2015-01-01

Abstract Living kidney transplantation offers the best treatment in terms of life‐expectancy and quality of life for those with end‐stage renal disease. The long‐term risks of living donor nephrectomy, although real, are very small, with evidence of good medium‐term outcomes. Who should be entitled to donate, and in which circumstances, is nevertheless a live question. We explore the ethical dimensions of a request by an individual to donate both of their kidneys during life: ‘dual living kidney donation’. Our ethical analysis is tethered to a hypothetical case study in which a father asks to donate a kidney to each of his twin boys. We explore the autonomy of the protagonists, alongside different dimensions of the public interest, such as the need to protect not only the recipients, but also the donor and even the wider community. Whilst acknowledging objections to ‘dual‐donation’, not least by reference to the harms that the donor might be expected to endure, we suggest there is a prima facie case for permitting this, provided that both donor and recipients are willing and that due attention is paid to such considerations as the autonomy and welfare of all parties, as well as to the wider ramifications of acting on such a request. We argue for broader interpretations of the concepts of autonomy and welfare, recognizing the importance of relationships and the relevance of more than merely physical well‐being. Equipped with such a holistic assessment, we suggest there is a prima facie case for allowing ‘dual living kidney donation’. PMID:26194324

The objective of this study was to evaluate progression to surgery rates for live and online seminar and assess weight loss outcome comparisons at 1-year postoperation. University Hospital Network, Allentown, PA, USA. The entry point into our program was an information seminar where prospective patients are educated about obesity, bariatric surgery, indications and contraindications, risks and benefits, and our center's process. Between January of 2009 and November of 2011, only live information seminars were offered. In November of 2011, we started offering an online information seminar to reach those who are unable to attend a live seminar. Tracking of live versus online seminar attendance was documented in our database. Between November 1, 2011 and September 30, 2015, 3484 people completed an information seminar. Of those, 2744 attendees came to a live seminar while 740 completed the online seminar. A significantly higher number of live seminar attendees, 78.1% (2144/2744) progressed to an office visit compared with online seminar attendees 66.5% (492/740), P<.0001. Similarly significant, 40.1% (1101/2744) of live seminar attendees progressed to surgery versus 29.7% (220/740) of online attendees (P<.0001). Sex (78.2% female for live seminar versus 79.5% female for online seminar, P = .65) and initial body mass index (46.3 ± 7.4 for live seminar versus 45.3 ± 7.1 for online seminar, P = .09) were very similar between the groups. Online seminar attendees' age (42.7 ± 12.1) was younger than that of the live seminar attendees' (47.3 ± 12.3) (P<.0001) but has little clinical value. Our results demonstrated that live seminar attendees are more likely to progress to surgery and therefore should continue to be offered. Copyright © 2018 American Society for Bariatric Surgery.

Modular fluorescence complementation sensors for live cell detection of epigenetic signals at endogenous genomic sites.

Investigation of the fundamental role of epigenetic processes requires methods for the locus-specific detection of epigenetic modifications in living cells. Here, we address this urgent demand by developing four modular fluorescence complementation-based epigenetic biosensors for live-cell microscopy applications. These tools combine engineered DNA-binding proteins with domains recognizing defined epigenetic marks, both fused to non-fluorescent fragments of a fluorescent protein. The presence of the epigenetic mark at the target DNA sequence leads to the reconstitution of a functional fluorophore. With this approach, we could for the first time directly detect DNA methylation and histone 3 lysine 9 trimethylation at endogenous genomic sites in live cells and follow dynamic changes in these marks upon drug treatment, induction of epigenetic enzymes and during the cell cycle. We anticipate that this versatile technology will improve our understanding of how specific epigenetic signatures are set, erased and maintained during embryonic development or disease onset.Tools for imaging epigenetic modifications can shed light on the regulation of epigenetic processes. Here, the authors present a fluorescence complementation approach for detection of DNA and histone methylation at endogenous genomic sites allowing following of dynamic changes of these marks by live-cell microscopy.

This study assesses the preparedness of long-term care facilities in Texas responding to Hurricanes Katrina and Rita. A 41-item questionnaire was mailed to facilities; the response rate was 42%. Among responding facilities, 4513 residents were evacuated, and 6% of respondents reported resident death. Financial losses were reported by 8% of nursing facilities and 45% of assisted living facilities due to transportation and staff overtime. Respondents indicated the need for improved disaster preparednesstraining, better coordination, and transportation. Changes in policy and practice will lead to better trained staff who will provide the care residents need for improved health outcomes during future public health disasters.

Zika virus infection during pregnancy is a cause of congenital brain abnormalities. Its consequences to pregnancies has made governments, national and international agencies issue advices and recommendations to women. There is a clear need to investigate how the Zika outbreak affects the decisions that women take concerning their lives and the life of their families, as well as how women are psychologically and emotionally dealing with the outbreak. We conducted a qualitative study to address the impact of the Zika epidemic on the family life of women living in Brazil, Puerto Rico, and the US, who were affected by it to shed light on the social repercussions of Zika. Women were recruited through the snowball sampling technique and data was collected through semi-structured interviews. We describe the effects in mental health and the coping strategies that women use to deal with the Zika epidemic. Zika is taking a heavy toll on women's emotional well-being. They are coping with feelings of fear, helplessness, and uncertainty by taking drastic precautions to avoid infection that affect all areas of their lives. Coping strategies pose obstacles in professional life, lead to social isolation, including from family and partner, and threaten the emotional and physical well-being of women. Our findings suggest that the impacts of the Zika epidemic on women may be universal and global. Zika infection is a silent and heavy burden on women's shoulders.

Parental cancer can have a significant impact on a family's psychosocial functioning and quality of life, whereby the children's situation is strongly related to parental coping and capacity. Such parents ask for more help in order to increase their care capacity, while the network is often insecure about how to help and thereby withdraw. They ask for guidance and training to be able to support cancer families. Based on this, the Cancer- Psycho-Educational Program for the SOcial NEtwork (PEPSONE) study was developed. To optimize social network support through a psycho-educational program for families living with parental cancer and their network members in order to increase parental capacity and thereby secure the children's safety and quality of life. A randomized controlled trial (RCT) in which families (N=60) living with parental cancer will be randomized to either an intervention group or a control group. The intervention will last for 3 hours and includes (1) introduction, (2) psycho-education (living with cancer in the family and the importance of social network support), and (3) discussion (this family's need for social support). Primary outcomes are social support, mental health, and quality of life, and secondary outcomes are resilience and parental capacity. Data will be collected by a set of questionnaires distributed to healthy parents (N=60) living with a partner with cancer, one child in the family between 8-18 years of age (N=60), and network members (N=210) of the intervention families at inclusion, and after 3 and 6 months. Comparing differences between the intervention group (n=30) and the control group (n=30), the power analysis shows that P<.05 and a statistical power = .80 would detect effect sizes of clinical interest. This paper presents the Cancer-PEPSON study's protocol to provide a broader understanding of the background and content of the program. The study is ongoing until August 2016 and the first results are anticipated to be finished

No statistician, social scientist or tarot card reader is needed to attest that the gap between the rich and poor in America is increasing. Further, most Americans don't care that much about it. There are also more rich people today living in the U.S. and there are more people living in poverty. Between 2000 and 2002, the number of Americans living in poverty increased by nearly 3 million to 34.6 million. Of these, 12% (or about one half a million persons) are living extreme poverty and many are children, with 16.7% likely to be poor (National Association of Social Workers, 2003).

People living with a substance use disorder (SUD) are a key population within the hepatitis C virus (HCV) epidemic. While integrated and community-based models of care have shown positive outcomes among this population, the literature has been primarily focused on the HIV context. This paper outlines a systematic review protocol on the impact of various integrated models of care, which includes HCV and SUD services, on various treatment, and health-related outcomes among this population. The objective of this review is to determine the impact of integrated models of care on HCV and addiction treatment and health-related outcomes for adults living with HCV and an SUD. We will search 5 databases, article reference lists, and abstracts from relevant conferences that investigate the impact of integrated models of care on treatment and health-related outcomes among people living with HCV and an SUD. Database searches will be conducted and titles, abstracts, and the full-text of the relevant studies will be independently reviewed in separate stages. The methodological quality of included studies will be assessed using a validated tool. Data from included articles will be extracted using a standardized form and synthesized in a narrative account. For this project, we have received funding from the Canadian Institute of Health Research. To date, we have completed the search strategy, reviewed the titles, abstracts, and full-texts. Grading the selected studies and qualitative synthesis of the results are currently under way, and we expect the final results to be submitted for publication in the fall of 2018. The systematic review will describe different integrated models of care that could be effective in improving the health and well-being of people living with HCV and an SUD. Results of this review could also identify quality improvement strategies to minimize the health and cost burden imposed on patients, healthcare professionals, and the healthcare system.

Psychoanalysis and creative living.

Rubin, Jeffrey B

Psychoanalysis is ambivalent about creativity and its own creative potential. On the one hand, psychoanalysis offers enormous resources for elucidating obstacles to creativity, that way of living, making and relating to self and others that is fresh, vital, unpredictable and open to feedback and evolution. On the other hand, when we analysts know too much beforehand about what a work of art really means or the fundamental and singular motives of creativity, then psychoanalysis unconsciously partakes of a perverse scenario in which the work of art serves as merely a means to the author's ends and is psychologically colonized. When psychoanalysis is The Discipline That Knows, then art has nothing new to teach psychoanalysts and our field is impoverished. "Psychoanalysis and Creative Living" attempts to elucidate how psychoanalysis could work through this tension between its creative and perverse possibilities and foster creative living.

Tyche and its dark comet absorb light like a dark light which is a negative black-body radiation. (1) Eddν=-c1dνd^3dνe^c2dνd/Td-1. Among it, Ed: the dark energy, νd: the dark frequence, Td: the dark temperature, c1d,c2d: the constant. So when they go near us, their wave has a against Doppler redshift as 0.000165. And they will inbreak solar system at the rate of 99AU/y, from the distance of 1,500AU and in 20 years. It can cause the broken ozonosphere, the lithosphere to crack, many big activity volcanic and the continental drift. And it can darked the light and colded the climate to the Great Ice Age. Not only it will break our environment by a special ``nuclear explosion'' under low temperature, but also the dark life will change the Genetic code of our life. So it will kill many lives and will produce new life. So it could trigger the Mass Extinction. We can bulid up a new pair of nuclear reactor (include dark nuclear energy) to drive a universal craft and can change the orbit of our earth for evading the impaction. We need a new life-information technology to develop our life and consciousness.

We examined the meaning of living with HIV/AIDS among women in Lebanon. Ten women living with HIV/AIDS (WLWHA) described their experiences via semistructured in-depth interviews. They navigated a process of HIV diagnosis acceptance that incorporated six overlapping elements: receiving the news, accessing care, starting treatment, navigating disclosure decisions, negotiating stigma, and maintaining stability. Through these elements, we provide a framework for understanding three major themes that were constructed during data analysis: Stand by my side: Decisions of disclosure; Being "sick" and feeling "normal": Interacting with self, others, and society; and Living day by day: focusing on the present. We contribute to the existing literature by providing a theoretical framework for understanding the process of diagnosis and sero-status acceptance among WLWHA. This was the first study of its kind to examine the meaning of living with HIV/AIDS among women in a Middle Eastern country.

Since cyclosporine A (CsA) had been used in renal transplant recipients, important improvements in short-term and long-term graft survivals have been detected. In spite of these improvements CsA seems to have several adverse effects. First, CsA leads to nephrotoxicity. Moreover, CsA affects the other organs and systems (skin, liver, nervous system, etc.) and causes, increased risks of infections and malignancies. Hypomagnesemia is one of the side effects of CsA therapy, but it is a rare condition in living related donor renal transplant recipients. It may also cause multi-system dysfunction, especially hypocalcemia and hypokalemia, which cannot be corrected without magnesium therapy. In addition, rhabdomyolysis was detected in animals, but it has not been reported in living related donor renal transplant recipients. In this case report, a living related donor renal transplant recipient who suffered from hypomagnesemia and mild rhabdomyolysis due to CsA therapy will be described and discussed.

[Concept of living conditions or social strata?--which approach is more suitable for describing unhealthy living circumstances of mothers?].

PubMed

Sperlich, S; Geyer, S

2010-11-01

The aim of this study was to identify living conditions associated with elevated health risks for mothers. Following up the debate on appropriate characterisation of social structure in modern societies, two different approaches, namely the 'social strata concept' and the 'concept of living conditions', were considered. Of particular interest was the question if the concept of living conditions, which is based on a broader definition of social status, allowed a more precise description of health-related living circumstances. The study was based on clinical data from 6,094 inpatients in Mother-Child rehabilitation centres in Germany. Taking socioeconomic status, household characteristics and psychosocial stressors into account seven typical living conditions of mothers could be identified by cluster analysis. Social status was measured by the Winkler Index. A moderate health-related gradient of increasing health risks with decreasing social position could be found for psychological and bodily disabilities. The approach of living conditions revealed that two living circumstances of mothers could be identified as being related to extremely poor health. These are i) dissatisfied single mothers with high degrees of psychosocial distress and lack of social support, and ii) married mothers with conflicts within the family and self-perceived lack of appreciation. Different from these findings, a pronounced social gradient could be found for overweight and smoking. Here the concept of social strata revealed in part excessive risks compared to the concept of living conditions. Overall, the integration of further social determinants allowed a more detailed insight into health-related living conditions, which are not solely determined by socioeconomic position. A global answer about the adequacy of the 'social strata concept' versus 'concept of living conditions' for identifying unhealthy living conditions could not be given because the relevance of both conceptual frameworks

Risk appreciation for living kidney donors: another new subspecialty?

PubMed

Steiner, Robert W

2004-05-01

Quantitative estimates of the risk of end stage renal disease (ESRD) for living donors would seem essential to defensible donor selection practices, as the 'safe/unsafe' model for donor selection is not viable. All kidney donors take risk, and four fundamental, qualitative criteria should instead be used to decide when donor rejection is justified. These criteria are lack of donor education about transplantation, donor irrationality, lack of free and voluntary donation, and/or that donor acceptance would unavoidably threaten the public trust or the integrity of the center's selection procedures. Such a data-based selection policy, with explicit documentation of unbiased and comprehensive donor education, will help neutralize the center's self interest in a more defensible way than by rejecting 'complicated' kidney donors out of hand, and in a more practical way than by the creation of center-independent donor counselors or waiting for donor registries to come to fruition. Living kidney donors with isolated medical abnormalities comprise a sizable subset of at risk donors for whom center acceptance practices vary markedly. This population provides a paradigm opportunity for quantitative risk estimation and counseling.

The US Bureau of Labor Statistics lists several problems associated with using the CPI as a cost-of-living index where the proportion of 2-worker families is increasing, population is shifting, and work week hours are changing. This study shows how to compute cost-of-living indexes which are inexpensive to update, use less restrictive assumptions about consumer preferences, do not require statistical estimation, and handle the problem of increasing numbers of families where both the husband and wife work. This study attempts to how widely in fact the CPI varies with alternative true cost-of-living varies with alternative true cost-of-living indexes although in the end this de facto cost-of-living measure holds up quite well. In times of severe price inflation people change their preferences by substitution, necessitating a flexible cost-of-living index that accounts for this fundamental economic behavior.

The shortage of cadaveric organs and increased success of living donor transplantation support the use of living organ donors. Clinical social workers have the opportunity to explore a variety of donor-specific issues when performing psychosocial evaluations of living donors, including motivation, psychological stability, and personal and family consequences of donation, as well as the direct and indirect financial consequences faced by living donors. Although most donor-related medical costs are covered, other associated expenses are not reimbursable and may put donors at risk for financial hardship. Out-of-pocket expenses also serve as a disincentive to donate for some volunteers. During the evaluation process, healthcare professionals should openly discuss how surgery, recovery, and any potential complications might impact prospective donors' financial situation. Donors can then decide whether they are able to realistically handle the costs of donation. We present the financial dilemmas experienced by many living donors and highlight efforts that have been made to deal with them.

HIV is a global pandemic. However, anti-retroviral therapy (ART) has transformed the prognosis and providing compliance is good, a normal life expectancy can be anticipated. This has led to a growing population of people with chronic prevalent, treated infection living to older ages. Musculoskeletal symptoms, particularly musculoskeletal pain, is common in HIV patients and, with resumption of near-normal immune function, HIV-infected patients develop inflammatory rheumatic diseases which require assessment and management in rheumatology clinics. Moreover, it is becoming apparent that avascular necrosis and osteoporosis are common comorbidities of HIV. This review will contextualise the prevalence of musculoskeletal symptoms in HIV, informed by data from a UK-based clinic and will discuss the management of active inflammatory rheumatic diseases amongst HIV-infected patients taking ART, highlighting known drug interactions.

Background: Use of administrative data for outcomes assessment in living kidney donors is increasing given the rarity of complications and challenges with loss to follow-up. Objective: To assess the validity of living donor nephrectomy in health care administrative databases compared with the reference standard of manual chart review. Design: Retrospective cohort study. Setting: 5 major transplant centers in Ontario, Canada. Patients: Living kidney donors between 2003 and 2010. Measurements: Sensitivity and positive predictive value (PPV). Methods: Using administrative databases, we conducted a retrospective study to determine the validity of diagnostic and procedural codes for living donor nephrectomies. The reference standard was living donor nephrectomies identified through the province’s tissue and organ procurement agency, with verification by manual chart review. Operating characteristics (sensitivity and PPV) of various algorithms using diagnostic, procedural, and physician billing codes were calculated. Results: During the study period, there were a total of 1199 living donor nephrectomies. Overall, the best algorithm for identifying living kidney donors was the presence of 1 diagnostic code for kidney donor (ICD-10 Z52.4) and 1 procedural code for kidney procurement/excision (1PC58, 1PC89, 1PC91). Compared with the reference standard, this algorithm had a sensitivity of 97% and a PPV of 90%. The diagnostic and procedural codes performed better than the physician billing codes (sensitivity 60%, PPV 78%). Limitations: The donor chart review and validation study was performed in Ontario and may not be generalizable to other regions. Conclusions: An algorithm consisting of 1 diagnostic and 1 procedural code can be reliably used to conduct health services research that requires the accurate determination of living kidney donors at the population level.

Willed action, free will, and the stochastic neurodynamics of decision-making

It is shown that the randomness of the firing times of neurons in decision-making attractor neuronal networks that is present before the decision cues are applied can cause statistical fluctuations that influence the decision that will be taken. In this rigorous sense, it is possible to partially predict decisions before they are made. This raises issues about free will and determinism. There are many decision-making networks in the brain. Some decision systems operate to choose between gene-specified rewards such as taste, touch, and beauty (in for example the peacock's tail). Other processes capable of planning ahead with multiple steps held in working memory may require correction by higher order thoughts that may involve explicit, conscious, processing. The explicit system can allow the gene-specified rewards not to be selected or deferred. The decisions between the selfish gene-specified rewards, and the explicitly calculated rewards that are in the interests of the individual, the phenotype, may themselves be influenced by noise in the brain. When the explicit planning system does take the decision, it can report on its decision-making, and can provide a causal account rather than a confabulation about the decision process. We might use the terms “willed action” and “free will” to refer to the operation of the planning system that can think ahead over several steps held in working memory with which it can take explicit decisions. Reduced connectivity in some of the default mode cortical regions including the precuneus that are active during self-initiated action appears to be related to the reduction in the sense of self and agency, of causing willed actions, that can be present in schizophrenia.
