Ethical issues with colorectal cancer screening-a systematic review.

PubMed

Hofmann, Bjørn

2017-06-01

Colorectal cancer (CRC) screening is widely recommended and implemented. However, sometimes CRC screening is not implemented despite good evidence, and some types of CRC screening are implemented despite lack of evidence. The objective of this article is to expose and elucidate relevant ethical issues in the literature on CRC screening that are important for open and transparent deliberation on CRC screening. An axiological question-based method is used for exposing and elucidating ethical issues relevant in HTA. A literature search in MEDLINE, Embase, PsycINFO, PubMed Bioethics subset, ISI Web of Knowledge, Bioethics Literature Database (BELIT), Ethics in Medicine (ETHMED), SIBIL Base dati di bioetica, LEWI Bibliographic Database on Ethics in the Sciences and Humanities, and EUROETHICS identified 870 references of which 114 were found relevant according to title and abstract. The content of the included papers were subject to ethical analysis to highlight the ethical issues, concerns, and arguments. A wide range of important ethical issues were identified. The main benefits are reduced relative CRC mortality rate, and potentially incidence rate, but there is no evidence of reduced absolute mortality rate. Potential harms are bleeding, perforation, false test results, overdetection, overdiagnosis, overtreatment (including unnecessary removal of polyps), and (rarely) death. Other important issues are related to autonomy and informed choice equity, justice, medicalization, and expanding disease. A series of important ethical issues have been identified and need to be addressed in open and transparent deliberation on CRC screening. © 2016 John Wiley & Sons, Ltd.

Cystic fibrosis lung transplantation.

Braun, Andrew T; Merlo, Christian A

2011-11-01

This review summarizes recently published investigations on issues pertaining to cystic fibrosis (CF) lung transplantation. We specifically focus on indications and candidate selection as well as infectious and noninfectious issues specific to CF lung transplant recipients. Recent studies have focused on candidate adequacy in high-risk CF patients. We review the current literature on individuals who develop respiratory failure requiring mechanical ventilation and those patients with a pretransplant diagnosis of pulmonary hypertension. Furthermore, the management of peri-operative infectious issues is reviewed including recurrent infections with multidrug-resistant bacterial, mycobacterial, and fungal organisms. Other CF-specific issues addressed include common comorbidities such as CF-related diabetes, gastroesophageal reflux, CF liver disease, and bone metabolism. Lung transplantation is a limited, but potentially life-saving therapeutic option for patients with CF. Optimal candidate selection and awareness of CF-specific issues in the pretransplant and posttransplant setting may lead to better long-term outcomes. © 2011 Wolters Kluwer Health | Lippincott Williams & Wilkins

Neuroimaging techniques for memory detection: scientific, ethical, and legal issues.

PubMed

Meegan, Daniel V

2008-01-01

There is considerable interest in the use of neuroimaging techniques for forensic purposes. Memory detection techniques, including the well-publicized Brain Fingerprinting technique (Brain Fingerprinting Laboratories, Inc., Seattle WA), exploit the fact that the brain responds differently to sensory stimuli to which it has been exposed before. When a stimulus is specifically associated with a crime, the resulting brain activity should differentiate between someone who was present at the crime and someone who was not. This article reviews the scientific literature on three such techniques: priming, old/new, and P300 effects. The forensic potential of these techniques is evaluated based on four criteria: specificity, automaticity, encoding flexibility, and longevity. This article concludes that none of the techniques are devoid of forensic potential, although much research is yet to be done. Ethical issues, including rights to privacy and against self-incrimination, are discussed. A discussion of legal issues concludes that current memory detection techniques do not yet meet United States standards of legal admissibility.

Yehuda, Rachel; Vermetten, Eric; McFarlane, Alexander C.; Lehrner, Amy

2014-01-01

Given the unique context of warzone engagement, which may include chronic threat, multiple and lengthy deployments, and loss, there is a need to understand whether and to what extent knowledge about PTSD derived from studies of civilian trauma exposure is generalizeable to the military. This special issue on PTSD in the military addresses a range of issues and debates related to mental health in military personnel and combat veterans. This article provides an overview of the issues covered in selected contributions that have been assembled for a special volume to consider issues unique to the military. Several leading scholars and military experts have contributed papers regarding: 1) prevalence rates of PTSD and other post-deployment mental health problems in different NATO countries, 2) the search for biomarkers of PTSD and the potential applications of such findings, and 3) prevention and intervention approaches for service members and veterans. The volume includes studies that highlight the divergence in prevalence rates of PTSD and other post-deployment mental health problems across nations and that discuss potential causes and implications. Included studies also provide an overview of research conducted in military or Veteran's Affairs settings, and overarching reviews of military-wide approaches to research, promotion of resilience, and mental health interventions in the Unites States and across NATO and allied ISAF partners.

To provide future directions for Internet research based on issues raised during the recruitment process of an Internet survey of oncology nurses. Throughout the research process, the research staff recorded issues as they arose and wrote memos regarding recruitment issues and possible reasons for the issues. Weekly group discussions were conducted, and written records of the discussions were kept. The written memos and records were reviewed, and the content was analyzed. The recruitment issues included flexibility required, mutual trust, changing Internet dynamics, and potential selection bias. As the issues indicated, recruiting nurses for the study only through the Internet did not work well. For future Internet research, the authors suggest using multiple Internet and real settings for recruitment, a variety of strategies, the quota sampling method, and creative motivation strategies.

The implementation of a new clinical service is associated with anxiety and challenges that may prevent smooth and safe execution of the service. Unexpected issues may not be apparent until the actual clinical service commences. We present a novel approach to test the new clinical setting before actual implementation of our endovascular aortic repair service. In-situ simulation at the new clinical location would enable identification of potential process and system issues prior to implementation of the service. After preliminary planning, a simulation test utilising a case scenario with actual simulation of the entire care process was carried out to identify any logistic, equipment, settings or clinical workflow issues, and to trial a contingency plan for a surgical complication. All patient care including anaesthetic, surgical, and nursing procedures and processes were simulated and tested. Overall, 17 vital process and system issues were identified during the simulation as potential clinical concerns. They included difficult patient positioning, draping pattern, unsatisfactory equipment setup, inadequate critical surgical instruments, blood products logistics, and inadequate nursing support during crisis. In-situ simulation provides an innovative method to identify critical deficiencies and unexpected issues before implementation of a new clinical service. Life-threatening and serious practical issues can be identified and corrected before formal service commences. This article describes our experience with the use of simulation in pre-implementation testing of a clinical process or service. We found the method useful and would recommend it to others.

Pathways to potentially preventable hospitalizations for diabetes and heart failure: a qualitative analysis of patient perspectives.

2016-07-26

Potentially preventable hospitalizations (PPH) for heart failure (HF) and diabetes mellitus (DM) cost the United States over $14 billion annually. Studies about PPH typically lack patient perspectives, especially across diverse racial/ethnic groups with known PPH health disparities. English-speaking individuals with a HF or DM-related PPH (n = 90) at the largest hospital in Hawai'i completed an in-person interview, including open-ended questions on precipitating factors to their PPH. Using the framework approach, two independent coders identified patient-reported factors and pathways to their PPH. Seventy-two percent of respondents were under 65 years, 30 % were female, 90 % had health insurance, and 66 % had previously been hospitalized for the same problem. Patients' stories identified immediate, precipitating, and underlying reasons for the admission. Underlying background factors were critical to understanding why patients had the acute problems necessitating their hospitalizations. Six, non-exclusive, underlying factors included: extreme social vulnerability (e.g., homeless, poverty, no social support, reported by 54 % of respondents); health system interaction issues (e.g., poor communication with providers, 44 %); limited health-related knowledge (42 %); behavioral health issues (e.g., substance abuse, mental illness, 36 %); denial of illness (27 %); and practical problems (e.g., too busy, 6 %). From these findings, we developed a model to understand an individual's pathways to a PPH through immediate, precipitating, and underlying factors, which could help identify potential intervention foci. We demonstrate the model's utility using five examples. In a young, predominately insured population, factors well outside the traditional purview of the hospital, or even clinical medicine, critically influenced many PPH. Patient perspectives were vital to understanding this issue. Innovative partnerships and policies should address these issues, including linkages to social services and behavioral health.

2011-01-01

The diversion, misuse, and non-medically supervised use of buprenorphine and buprenorphine/naloxone by opioid users are reviewed. Buprenorphine and buprenorphine/naloxone are used globally as opioid analgesics and in the treatment of opioid dependency. Diversion of buprenorphine and buprenorphine/naloxone represents a complex medical and social issue, and has been widely documented in various geographical regions throughout the world. We first discuss the clinical properties of buprenorphine and its abuse potential. Second, we discuss its diversion and illicit use on an international level, as well as motivations for those activities. Third, we examine the medical risks and benefits of buprenorphine’s non-medically supervised use and misuse. These risks and benefits include the effect of buprenorphine’s use on HIV risk and the risk of its concomitant use with other medications and drugs of abuse. Finally, we discuss the implications of diversion, misuse, and non-medically supervised use (including potential measures to address issues of diversion); and potential areas for further research.

Comment on 'Current Budget of the Atmospheric Electric Global Circuit'

NASA Technical Reports Server (NTRS)

Driscoll, Kevin T.; Blakeslee, Richard J.

1996-01-01

In this paper, three major issues relevant to Kasemir's new model will be addressed. The first concerns Kasemir's assertion that there are significant differences between the potentials associated with the new model and the conventional model. A recalculation of these potentials reveals that both models provide equivalent results for the potential difference between the Earth and ionosphere. The second issue to be addressed is Kasemir's assertion that discrepancies in the electric potentials associated with both models can be attributed to modeling the Earth as a sphere, instead of as a planar surface. A simple analytical comparison will demonstrate that differences in the equations for the potentials of the atmosphere derived with a spherical and a planar Earth are negligible for applications to global current flow. Finally, the third issue to be discussed is Kasemir's claim that numerous aspects of the conventional model are incorrect, including the role of the ionosphere in global current flow as well as the significance of cloud-to-ground lightning in supplying charge to the global circuit. In order to refute these misconceptions, it will be shown that these aspects related to the flow of charge in the atmosphere are accurately described by the conventional model of the global circuit.

Wildenbos, G A; Peute, L W; Jaspers, M W M

2016-01-01

This paper discusses the preliminary results of a literature review on studies published in 2014-2015 concerning patient-centered mHealth applications' (apps) impact. Abstracts were included when they described a mHealth app targeted at patients and reported on the effects of this app on patient care. From a total of 559 potentially relevant articles, 17 papers were finally included. Nine studies reported a positive impact of the patient-centered mHealth app on patient care; 4 of these studies were randomized controlled trials. Measured impacts in the 17 studies focused on improving patients' physical activity, self-efficacy and medication adherence. Human factors issues potentially mediating these effects were discussed in all studies. Transitions in the interaction between healthcare providers and their patients were most often discussed as influencing the impact of the mHealth app. More research is needed, focussing on human issues mediating the effect of patient-centered mHealth apps to precipitate knowledge on the effectiveness of mHealth. This research should preferably be guided by socio-technical models.

We review the conservation issues facing migratory shorebird populations that breed in temperate regions and use wetlands in the non-breeding season. Shorebirds are excellent model organisms for understanding ecological, behavioural and evolutionary processes and are often used as indicators of wetland health. A global team of experienced shorebird researchers identified 45 issues facing these shorebird populations, and divided them into three categories (natural, current anthropogenic and future issues). The natural issues included megatsunamis, volcanoes and regional climate changes, while current anthropogenic threats encompassed agricultural intensification, conversion of tidal flats and coastal wetlands by human infrastructure developments and eutrophication of coastal systems. Possible future threats to shorebirds include microplastics, new means of recreation and infectious diseases. We suggest that this review process be broadened to other taxa to aid the identification and ranking of current and future conservation actions.

Has the question of e-waste opened a Pandora's box? An overview of unpredictable issues and challenges.

2018-01-01

Despite regulatory efforts and position papers, electrical and electronic waste (e-waste) remains ill-managed as evidenced by the extremely low rates of proper e-waste recycling (e-recycling) worldwide, ongoing illegal shipments to developing countries and constantly reported human health issues and environmental pollution. The objectives of this review are, first, to expose the complexity of e-waste problems, and then to suggest possible upstream and downstream solutions. Exploring e-waste issues is akin to opening a Pandora's box. Thus, a review of prevailing e-waste management practices reveals complex and often intertwined gaps, issues and challenges. These include the absence of any consistent definition of e-waste to date, a prevalent toxic potential still involving already banned or restricted hazardous components such as heavy metals and persistent and bioaccumulative organic compounds, a relentless growth in e-waste volume fueled by planned obsolescence and unsustainable consumption, problematic e-recycling processes, a fragile formal e-recycling sector, sustained and more harmful informal e-recycling practices, and more convoluted and unpredictable patterns of illegal e-waste trade. A close examination of the e-waste legacy contamination reveals critical human health concerns, including significant occupational exposure during both formal and informal e-recycling, and persistent environmental contamination, particularly in some developing countries. However, newly detected e-waste contaminants as well as unexpected sources and environmental fates of contaminants are among the emerging issues that raise concerns. Moreover, scientific knowledge gaps remain regarding the complexity and magnitude of the e-waste legacy contamination, specifically, a comprehensive characterization of e-waste contaminants, information on the scale of legacy contamination in developing countries and on the potential environmental damage in developed countries, and a stronger body of evidence of adverse health effects specifically ascribed to e-waste contaminants. However, the knowledge accumulated to date is sufficient to raise awareness and concern among all stakeholders. Potential solutions to curb e-waste issues should be addressed comprehensively, by focusing on two fronts: upstream and downstream. Potential upstream solutions should focus on more rational and eco-oriented consumer habits in order to decrease e-waste quantities while fostering ethical and sustained commitments from manufacturers, which include a limited usage of hazardous compounds and an optimal increase in e-waste recyclability. At the downstream level, solutions should include suitable and pragmatic actions to progressively reduce the illegal e-waste trade particularly through international cooperation and coordination, better enforcement of domestic laws, and monitoring in both exporting and receiving countries, along with the supervised integration of the informal sector into the recycling system of developing countries and global expansion of formal e-waste collection and recycling activities. Downstream solutions should also introduce stronger reverse logistics, together with upgraded, more affordable, and eco-friendly and worker-friendly e-recycling technologies to ensure that benefits are derived fully and safely from the great economic potential of e-waste.

There is a critical need for objective data to guide effective health promotion and care for homeless populations. However, many investigators exclude homeless populations from clinical trials due to practical concerns about conducting research with this population. This report is based on our experience and lessons learned while conducting two large NIH-funded randomized controlled trials targeting smoking cessation among persons who are homeless. The current report also addresses challenges when conducting clinical trials among homeless populations and offers potential solutions. Homeless individuals face several challenges including the need to negotiate daily access to food, clothing, and shelter. Some of the critical issues investigators encounter include recruitment and retention obstacles; cognitive impairment, mental health and substance abuse disorders; transportation and scheduling challenges; issues pertaining to adequate study compensation; the need for safety protocols for study staff; and issues related to protecting the wellbeing of these potentially vulnerable adults. Anticipating realistic conditions in which to conduct studies with participants who are homeless will help investigators to design efficient protocols and may improve the feasibility of conducting clinical trials involving homeless populations and the quality of the data collected by the researchers.

An overview of algae biofuel production and potential environmental impact.

PubMed

Menetrez, Marc Y

2012-07-03

Algae are among the most potentially significant sources of sustainable biofuels in the future of renewable energy. A feedstock with virtually unlimited applicability, algae can metabolize various waste streams (e.g., municipal wastewater, carbon dioxide from industrial flue gas) and produce products with a wide variety of compositions and uses. These products include lipids, which can be processed into biodiesel; carbohydrates, which can be processed into ethanol; and proteins, which can be used for human and animal consumption. Algae are commonly genetically engineered to allow for advantageous process modification or optimization. However, issues remain regarding human exposure to algae-derived toxins, allergens, and carcinogens from both existing and genetically modified organisms (GMOs), as well as the overall environmental impact of GMOs. A literature review was performed to highlight issues related to the growth and use of algal products for generating biofuels. Human exposure and environmental impact issues are identified and discussed, as well as current research and development activities of academic, commercial, and governmental groups. It is hoped that the ideas contained in this paper will increase environmental awareness of issues surrounding the production of algae and will help the algae industry develop to its full potential.

Our aim in conducting annual horizon scans is to identify issues that, although currently receiving little attention, may be of increasing importance to the conservation of biological diversity in the future. The 15 issues presented here were identified by a diverse team of 22 experts in horizon scanning, and conservation science and its application. Methods for identifying and refining issues were the same as in two previous annual scans and are widely transferable to other disciplines. The issues highlight potential changes in climate, technology and human behaviour. Examples include warming of the deep sea, increased cultivation of perennial grains, burning of Arctic tundra, and the development of nuclear batteries and hydrokinetic in-stream turbines.

Fetal growth: a review of terms, concepts and issues relevant to obstetrics.

PubMed

Mayer, C; Joseph, K S

2013-02-01

The perinatal literature includes several potentially confusing and controversial terms and concepts related to fetal size and growth. This article discusses fetal growth from an obstetric perspective and addresses various issues including the physiologic mechanisms that determine fetal growth trajectories, known risk factors for abnormal fetal growth, diagnostic and prognostic issues related to restricted and excessive growth and temporal trends in fetal growth. Also addressed are distinctions between fetal growth 'standards' and fetal growth 'references', and between fetal growth charts based on estimated fetal weight vs those based on birth weight. Other concepts discussed include the incidence of fetal growth restriction in pregnancy (does the frequency of fetal growth restriction increase or decrease with increasing gestation?), the obstetric implications of studies showing associations between fetal growth and adult chronic illnesses (such as coronary heart disease) and the need for customizing fetal growth standards.

Mitochondrial metals as a potential therapeutic target in neurodegeneration

PubMed Central

Grubman, A; White, A R; Liddell, J R

2014-01-01

Transition metals are critical for enzyme function and protein folding, but in excess can mediate neurotoxic oxidative processes. As mitochondria are particularly vulnerable to oxidative damage due to radicals generated during ATP production, mitochondrial biometal homeostasis must therefore be tightly controlled to safely harness the redox potential of metal enzyme cofactors. Dysregulation of metal functions is evident in numerous neurological disorders including Alzheimer's disease, stroke, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis and Friedrich's ataxia. This review describes the mitochondrial metal defects in these disorders and highlights novel metal-based therapeutic approaches that target mitochondrial metal homeostasis in neurological disorders.

The Last Arctic Sea Ice Refuge

Pfirman, S. L.; Tremblay, B.; Newton, R.; Fowler, C.

2010-12-01

Summer sea ice may persist along the northern flank of Canada and Greenland for decades longer than the rest of the Arctic, raising the possibility of a naturally formed refugium for ice-associated species. Observations and models indicate that some ice in this region forms locally, while some is transported to the area by winds and ocean currents. Depending on future changes in melt patterns and sea ice transport rates, both the central Arctic and Siberian shelf seas may be sources of ice to the region. An international system of monitoring and management of the sea ice refuge, along with the ice source regions, has the potential to maintain viable habitat for ice-associated species, including polar bears, for decades into the future. Issues to consider in developing a strategy include: + the likely duration and extent of summer sea ice in this region based on observations, models and paleoenvironmental information + the extent and characteristics of the “ice shed” contributing sea ice to the refuge, including its dynamics, physical and biological characteristics as well as potential for contamination from local or long-range sources + likely assemblages of ice-associated species and their habitats + potential stressors such as transportation, tourism, resource extraction, contamination + policy, governance, and development issues including management strategies that could maintain the viability of the refuge.

Protecting Ideas: Ethical and Legal Considerations When a Grant's Principal Investigator Changes.

PubMed

Koniaris, Leonidas G; Coombs, Mary I; Meslin, Eric M; Zimmers, Teresa A

Ethical issues related the responsible conduct of research involve questions concerning the rights and obligations of investigators to propose, design, implement, and publish research. When a principal investigator (PI) transfers institutions during a grant cycle, financial and recognition issues need to be addressed to preserve all parties' obligations and best interests in a mutually beneficial way. Although grants often transfer with the PI, sometimes they do not. Maintaining a grant at an institution after the PI leaves does not negate the grantee institution's obligation to recognize the PI's original ideas, contributions, and potential rights to some forms of expression and compensation. Issues include maintaining a role for the PI in determining how to take credit for, share and publish results that involve his or her original ideas. Ascribing proper credit can become a thorny issue. This paper provides a framework for addressing situations and disagreements that may occur when a new PI continues the work after the original PI transfers. Included are suggestions for proactively developing institutional mechanisms that address such issues. Considerations include how to develop solutions that comply with the responsible conduct of research, equitably resolve claims regarding reporting of results, and avoid the possibility of plagiarism.

Coalbed methane produced water in China: status and environmental issues.

PubMed

Meng, Yanjun; Tang, Dazhen; Xu, Hao; Li, Yong; Gao, Lijun

2014-01-01

As one of the unconventional natural gas family members, coalbed methane (CBM) receives great attention throughout the world. The major associated problem of CBM production is the management of produced water. In the USA, Canada, and Australia, much research has been done on the effects and management of coalbed methane produced water (CMPW). However, in China, the environmental effects of CMPW were overlooked. The quantity and the quality of CMPW both vary enormously between coal basins or stratigraphic units in China. The unit produced water volume of CBM wells in China ranges from 10 to 271,280 L/well/day, and the concentration of total dissolved solids (TDS) ranges from 691 to 93,898 mg/L. Most pH values of CMPW are more than 7.0, showing the alkaline feature, and the Na-HCO3 and Na-HCO3-Cl are typical types of CMPW in China. Treatment and utilization of CMPW in China lag far behind the USA and Australia, and CMPW is mainly managed by surface impoundments and evaporation. Currently, the core environmental issues associated with CMPW in China are that the potential environmental problems of CMPW have not been given enough attention, and relevant regulations as well as environmental impact assessment (EIA) guidelines for CMPW are still lacking. Other potential issues in China includes (1) water quality monitoring issues for CMPW with special components in special areas, (2) groundwater level decline issues associated with the dewatering process, and (3) potential environmental issues of groundwater pollution associated with hydraulic fracturing.

2010-01-01

Clinical trials of stem cell transplantation raise ethical issues that are intertwined with scientific and design issues, including choice of control group and intervention, background interventions, endpoints, and selection of subjects. We recommend that the review and IRB oversight of stem cell clinical trials should be strengthened. Scientific and ethics review should be integrated in order to better assess risks and potential benefits. Informed consent should be enhanced by assuring that participants comprehend key aspects of the trial. For the trial to yield generalizable knowledge, negative findings and serious adverse events must be reported.

Selection bias in rheumatic disease research.

2014-07-01

The identification of modifiable risk factors for the development of rheumatic conditions and their sequelae is crucial for reducing the substantial worldwide burden of these diseases. However, the validity of such research can be threatened by sources of bias, including confounding, measurement and selection biases. In this Review, we discuss potentially major issues of selection bias--a type of bias frequently overshadowed by other bias and feasibility issues, despite being equally or more problematic--in key areas of rheumatic disease research. We present index event bias (a type of selection bias) as one of the potentially unifying reasons behind some unexpected findings, such as the 'risk factor paradox'--a phenomenon exemplified by the discrepant effects of certain risk factors on the development versus the progression of osteoarthritis (OA) or rheumatoid arthritis (RA). We also discuss potential selection biases owing to differential loss to follow-up in RA and OA research, as well as those due to the depletion of susceptibles (prevalent user bias) and immortal time bias. The lesson remains that selection bias can be ubiquitous and, therefore, has the potential to lead the field astray. Thus, we conclude with suggestions to help investigators avoid such issues and limit the impact on future rheumatology research.

Prescription opioid abuse, pain and addiction: Clinical issues and implications

PubMed Central

LING, WALTER; MOONEY, LARISSA; HILLHOUSE, MAUREEN

2014-01-01

Issues Prescription opioid misuse in the USA has increased over threefold since 1990 to epidemic proportions, with substantial increases in prescription opioid use also reported in other countries, such as Australia and New Zealand. The broad availability of prescription pain medications, coupled with public misconceptions about their safety and addictive potential, have contributed to the recent surge in non-medical use of prescription opioids and corresponding increases in treatment admissions for problems related to opioid misuse. Given competing pressures faced by physicians to both diagnose and treat pain syndromes and identify individuals at risk for addictive disorders, the use of opioids in the treatment of pain poses a significant clinical challenge. Approach This paper reviews the interaction between pain and opioid addiction with a focus on clinical management issues, including risk factors for opioid dependence in patients with chronic pain and the use of assessment tools to identify and monitor at-risk individuals. Treatment options for opioid dependence and pain are reviewed, including the use of the partial μ agonist buprenorphine in the management of concurrent pain and opioid addiction. Implications Physicians should strive to find a reasonable balance between minimising potential adverse effects of opioid medications without diminishing legitimate access to opioids for analgesia. Conclusions The article discusses the need to identify methods for minimising risks and negative consequences associated with opioid analgesics and poses research directions, including the development of abuse-deterrent opioid formulations, genetic risk factors for opioid dependence and opioid-induced hyperalgesia as a potential target for medication therapy.

Stevens, G. H.; Anzic, G.

1979-01-01

Issues and results in a NASA study of the potential concepts and markets for a multibeam 30/20 GHz domestic satellite system in the 1990s are presented. Issues considered include the reduction of signal attenuation due to rain, beam-beam interference isolation in the multibeam system, the method of access/modulation (FDMA, TDMA or hybrid) and the market for reduced reliability and wideband services. A hypothetical demonstration payload configuration which would attempt to resolve these issues is illustrated. The communications payload would employ a system of seven contiguous coverage spots in order to demonstrate a typical cell in a contiguous beam system having extensive frequency re-use, as in a direct-to-user system, and a single spot, typical of a trunking system, to determine signal isolation. The payload could be carried on several existing buses and is illustrated on an MMS bus.

Emerging Environmental Justice Issues in Nuclear Power and Radioactive Contamination.

PubMed

Kyne, Dean; Bolin, Bob

2016-07-12

Nuclear hazards, linked to both U.S. weapons programs and civilian nuclear power, pose substantial environment justice issues. Nuclear power plant (NPP) reactors produce low-level ionizing radiation, high level nuclear waste, and are subject to catastrophic contamination events. Justice concerns include plant locations and the large potentially exposed populations, as well as issues in siting, nuclear safety, and barriers to public participation. Other justice issues relate to extensive contamination in the U.S. nuclear weapons complex, and the mining and processing industries that have supported it. To approach the topic, first we discuss distributional justice issues of NPP sites in the U.S. and related procedural injustices in siting, operation, and emergency preparedness. Then we discuss justice concerns involving the U.S. nuclear weapons complex and the ways that uranium mining, processing, and weapons development have affected those living downwind, including a substantial American Indian population. Next we examine the problem of high-level nuclear waste and the risk implications of the lack of secure long-term storage. The handling and deposition of toxic nuclear wastes pose new transgenerational justice issues of unprecedented duration, in comparison to any other industry. Finally, we discuss the persistent risks of nuclear technologies and renewable energy alternatives.

Notify patients of a potential exposure to hepatitis C virus, coordinate testing, and provide follow-up counseling. A team was convened to identify various needs in developing a patient care call center. The areas addressed included the following: location, hours, and duration; telephone accessibility; tracking calls and test results; billing; staffing; notification; and potential issues requiring additional evaluation. Disclosure letters were sent to 1275 patients; 57 letters were not deliverable. There were 245 calls to the helpline from October 25 through November 15. Lessons learned centered on hours of availability, staffing, use of an automated phone system and email communication, tracking results, and billing issues. A successful patient notification and follow-up effort requires a multidisciplinary team, internal and external communication, collection of data over an extended period, and coordination of patient information.

From shame to shame resilience: narratives of counselor trainees with eating issues.

PubMed

Dayal, Helena; Weaver, Kathryn; Domene, José F

2015-02-01

Using narrative analysis, the experiences of 7 Canadian counselor trainees with eating issues were explored for meanings of shame and resilience. Shame was experienced as layers of discounting and disconnection from self and others, which served as barriers to help seeking and recovery. Trainees' attempts to overcome shame were characterized by a dialectic conflict of protecting shame vs. prioritizing recovery. Finding a culture of safety and belonging, invalidating perfection, and redefining ideals emerged as elements that fostered resilience from the layers of shame. Recommendations for future research include exploring the important features of social support and examining how safe disclosure contributes to overcoming shame. Potential implications for counselor education programs include introducing self-care initiatives, discussions about counselor wellness and ethical practice, and education on eating issues. © The Author(s) 2014.

Environmental change poses risks to societies, including disrupting social and economic systems such as migration. At the same time, migration is an effective adaptation to environmental and other risks. We review novel science on interactions between migration, environmental risks and climate change. We highlight emergent findings, including how dominant flows of rural to urban migration mean that populations are exposed to new risks within destination areas and the requirement for urban sustainability. We highlight the issue of lack of mobility as a major issue limiting the effectiveness of migration as an adaptation strategy and leading to potentially trapped populations. The paper presents scenarios of future migration that show both displacement and trapped populations over the incoming decades. Papers in the special issue bring new insights from demography, human geography, political science and environmental science to this emerging field.

PubMed

New, Peter Wayne; Eriks-Hoogland, Inge; Scivoletto, Giorgio; Reeves, Ronald K; Townson, Andrea; Marshall, Ruth; Rathore, Farooq A

2017-01-01

Background: Non-traumatic spinal cord dysfunction (SCDys) is caused by a large range of heterogeneous etiologies. Although most aspects of rehabilitation for traumatic spinal cord injury and SCDys are the same, people with SCDys have some unique rehabilitation issues. Purpose: This article presents an overview of important clinical rehabilitation principles unique to SCDys. Methods: Electronic literature search conducted (January 2017) using MEDLINE and Embase (1990-2016) databases for publications regarding SCDys. The focus of the literature search was on identifying publications that present suggestions regarding the clinical rehabilitation of SCDys. Results: The electronic search of MEDLINE and Embase identified no relevant publications, and the publications included were from the authors' libraries. A number of important clinical rehabilitation principles unique to people with SCDys were identified, including classification issues, general rehabilitation issues, etiology-specific issues, and a role for the rehabilitation physician as a diagnostic clinician. The classification issues were regarding the etiology of SCDys and the International Standards for Neurological Classification of Spinal Cord Injury. The general rehabilitation issues were predicting survival, improvement, and rehabilitation outcomes; admission to spinal rehabilitation units, including selection decision issues; participation in rehabilitation; and secondary health conditions. The etiology-specific issues were for SCDys due to spinal cord degeneration, tumors, and infections. Conclusions: Although there are special considerations regarding the rehabilitation of people with SCDys, such as the potential for progression of the underlying condition, functional improvement is typically significant with adequate planning of rehabilitation programs and special attention regarding the clinical condition of patients with SCDys.

This survey assessed rural parents' (n = 374) perceptions of the characteristics, content, and comfort level of discussions about sexual issues with their teens. Almost all parents (94%) reported they had talked with their teens about sex. Two-thirds (65%) reported being comfortable talking with their teens about sexual issues. From a list of 17 potential topical areas in sexual communication, parents were most likely to discuss with their teens the responsibilities of being a parent (46%), sexually transmitted diseases (40%), dating behavior (37%), and not having sex until marriage (36%). Most parents (80%) believed that the majority of sexuality education should be provided by the family and supplemented by outside organizations, preferably schools. Almost all parents (92%) believed sexuality education should include information on birth control methods including condoms. Almost two of three parents (64%) believed schools should begin teaching sexuality education before students reach seventh grade. Parents (52%) claimed they could best be helped in communicating with their teens by receiving a regular newsletter regarding teen sexual issues.

Telemedicine: legal and licensure issues

Wood, Michael B.; Whelan, Leo J.

1995-10-01

The National Information Infrastructure program offers a great opportunity for the United States to capitalize on remarkable technological advancements over a broad range of applications benefiting society. One such application, telemedicine, has the potential to offer widespread access to sophisticated medical care, curtailed health care delivery costs, and homogeneous health and health-related educational opportunities. However, there are a variety of barriers to widespread application of telemedicine once the technical infrastructure of the information highway is well established and ubiquitous. These barriers include technical limitations, reimbursement issues, equipment and networking costs, and appropriate scientific studies to document efficacy and cost effectiveness. These issues may prove to be only transient disincentives which can be surmounted. Additional barriers exist, however, that may not be as readily resolved by traditional methods of analysis and more widespread practice applications. These political and regulatory obstacles will require clarification of the issues and solutions based on national consensus. It is the purpose of this discussion to amplify on these particular barriers which include licensure and tort jurisdiction.

Collaborative Paradigm of Preventive, Personalized, and Precision Medicine With Point-of-Care Technologies.

PubMed

Dhawan, Atam P

2016-01-01

Recent advances in biosensors, medical instrumentation, and information processing and communication technologies (ICT) have enabled significant improvements in healthcare. However, these technologies have been mainly applied in clinical environments, such as hospitals and healthcare facilities, under managed care by well-trained and specialized individuals. The global challenge of providing quality healthcare at affordable cost leads to the proposed paradigm of P reventive, Personalized, and Precision Medicine that requires a seamless use of technology and infrastructure support for patients and healthcare providers at point-of-care (POC) locations including homes, semi or pre-clinical facilities, and hospitals. The complexity of the global healthcare challenge necessitates strong collaborative interdisciplinary synergies involving all stakeholder groups including academia, federal research institutions, industry, regulatory agencies, and clinical communities. It is critical to evolve with collaborative efforts on the translation of research to technology development toward clinical validation and potential healthcare applications. This special issue is focused on technology innovation and translational research for POC applications with potential impact in improving global healthcare in the respective areas. Some of these papers were presented at the NIH-IEEE Strategic Conference on Healthcare Innovations and POC Technologies for Precision Medicine (HI-POCT) held at the NIH on November 9-10, 2015. The papers included in the Special Issue provide a spectrum of critical issues and collaborative resources on translational research of advanced POC devices and ICT into global healthcare environment.

BACKGROUND: During future long-duration space missions, countermeasures need to be developed to deal with psychosocial issues that might impact negatively on crewmember performance and well-being. METHODS: In our recently completed NASA-funded study of 5 U.S. astronauts, 8 Russian cosmonauts, and 42 U.S. and 16 Russian mission control personnel who participated in the Shuttle/Mir program, we evaluated a number of important psychosocial issues such as group tension, cohesion, leadership role, and the displacement of negative emotions from crewmembers to people in mission control and from mission control personnel to management. RESULTS: Based on our findings, which are reviewed, a number of psychosocial countermeasures are suggested to help ameliorate the negative impact of potential psychosocial problems during future manned space missions. CONCLUSIONS: Crewmembers should be selected not only to rule out psychopathology but also to select-in for group compatibility and facility in a common language. Training should include briefings and team building related to a number of psychosocial issues and should involve both crewmembers and mission control personnel. During the mission, both experts on the ground and the crewmembers themselves should be alert to potential interpersonal problems, including the displacement of negative emotions from the crew to the ground. Supportive activities should consist of both individual and interpersonal strategies, including an awareness of changing leisure time needs. Finally, attention should be given to postmission readjustment and to supporting the families on Earth.

Imaginable Technologies for Human Missions to Mars

NASA Technical Reports Server (NTRS)

Bushnell, Dennis M.

2007-01-01

The thesis of the present discussion is that the simultaneous cost and inherent safety issues of human on-site exploration of Mars will require advanced-to-revolutionary technologies. The major crew safety issues as currently identified include reduced gravity, radiation, potentially extremely toxic dust and the requisite reliability for years-long missions. Additionally, this discussion examines various technological areas which could significantly impact Human-Mars cost and safety. Cost reductions for space access is a major metric, including approaches to significantly reduce the overall up-mass. Besides fuel, propulsion and power systems, the up-mass consists of the infrastructure and supplies required to keep humans healthy and the equipment for executing exploration mission tasks. Hence, the major technological areas of interest for potential cost reductions include propulsion, in-space and on-planet power, life support systems, materials and overall architecture, systems, and systems-of-systems approaches. This discussion is specifically offered in response to and as a contribution to goal 3 of the Presidential Exploration Vision: "Develop the Innovative Technologies Knowledge and Infrastructures both to explore and to support decisions about the destinations for human exploration".

Three themes emerged from the data: (1) four service delivery models were identified in operation, including both those expected models involving genetic counselors and variations that do not route through the formal genetic service program; (2) multiple barriers to sharing and using genetic information were perceived, including technological, organizational, institutional, legal, ethical, and social issues; and (3) impediments to wider use of genetic testing technology, including variable understanding of genetic test utilities among clinicians and the limited capacity of clinical genetic services. Targeting these problems, information technologies and knowledge management tools have the potential to support key tasks in genetic services delivery, improve knowledge processes, and enhance knowledge networks. Because of the effect of issues in genetic information and knowledge management, the potential of human genetic variation knowledge to enhance health care delivery has been put on a "leash."

Forinash, Betsy; Schultheisz, Daniel; Peake, Tom

2013-07-01

Following the decision to withdraw the Yucca Mountain license application, the Department of Energy created a Blue Ribbon Commission (BRC) on America's Nuclear Future, tasked with recommending a national strategy to manage the back end of the nuclear fuel cycle. The BRC issued its final report in January 2012, with recommendations covering transportation, storage and disposal of spent nuclear fuel (SNF); potential reprocessing; and supporting institutional measures. The BRC recommendations on disposal of SNF and high-level waste (HLW) are relevant to the U.S. Environmental Protection Agency (EPA), which shares regulatory responsibility with the Nuclear Regulatory Commission (NRC): EPA issues 'generallymore » applicable' performance standards for disposal repositories, which are then implemented in licensing. For disposal, the BRC endorses developing one or more geological repositories, with siting based on an approach that is adaptive, staged and consent-based. The BRC recommends that EPA and NRC work cooperatively to issue generic disposal standards-applying equally to all sites-early in any siting process. EPA previously issued generic disposal standards that apply to all sites other than Yucca Mountain. However, the BRC concluded that the existing regulations should be revisited and revised. The BRC proposes a number of general principles to guide the development of future regulations. EPA continues to review the BRC report and to assess the implications for Agency action, including potential regulatory issues and considerations if EPA develops new or revised generic disposal standards. This review also involves preparatory activities to define potential process and public engagement approaches. (authors)« less

Ethical issues in obesity prevention for school children: a systematic qualitative review.

PubMed

Kahrass, Hannes; Strech, Daniel; Mertz, Marcel

2017-12-01

Planning and conducting preventive measures against obesity for school children is beset with ethical issues which should be known to make well-informed decisions. The goal of this study was to provide a comprehensive spectrum of these ethical issues by means of a systematic review. In this context, the study also assesses the value of different search strategies for ethical literature in public health. Literature was searched in Medline, EBSCO and others. Three different search strategies with varied scopes were applied and their output was compared. Qualitative content analysis was used for extracting and categorizing ethical issues. 109 publications (published from 1995 to 2015) were finally included. The qualitative analysis resulted in 60 potentially relevant ethical issues. The three search strategies showed substantial differences regarding their search results. The presented spectrum provides an initial evidence base for dealing with ethical issues adequately. The findings of the study further suggest that a broader scope is more fruitful for systematic reviews on ethical issues in the field of public health.

Carpooling: status and potential

Kendall, D.C.

1975-06-01

Studies were conducted to analyze the status and potential of work-trip carpooling as a means of achieving more efficient use of the automobile. Current and estimated maximum potential levels of carpooling are presented together with analyses revealing characteristics of carpool trips, incentives, impacts of increased carpooling and issues related to carpool matching services. National survey results indicate the average auto occupancy for urban work-trip is 1.2 passengers per auto. This value, and average carpool occupancy of 2.5, have been relatively stable over the last five years. An increase in work-trip occupancy from 1.2 to 1.8 would require a 100% increasemore » in the number of carpoolers. A model was developed to predict the maximum potential level of carpooling in an urban area. Results from applying the model to the Boston region were extrapolated to estimate a maximum nationwide potential between 47 and 71% of peak period auto commuters. Maximum benefits of increased carpooling include up to 10% savings in auto fuel consumption. A technique was developed for estimating the number of participants required in a carpool matching service to achieve a chosen level of matching among respondents, providing insight into tradeoffs between employer and regional or centralized matching services. Issues recommended for future study include incentive policies and their impacts on other modes, and the evaluation of new and ongoing carpool matching services. (11 references) (GRA)« less

Here we address the potential difference in rosuvastatin pharmacokinetics in Asians vs. whites. Our prospective study, reported in this issue, shows no ethnic difference when all subjects are wild-type for OATP1B1 and BCRP. We argue that although our study may be under powered to prove no ethnic difference, and that further confirmatory study is required, the virtual clinical study analysis, also reported in this issue, does not contradict the results of our prospective clinical study and that previous retrospective analysis of clinical studies does not include enough relevant subjects to conclude that wild-type OATP1B1 and BCRP do still demonstrate ethnic differences.

Koch, R J; Chavez, A; Dagum, P; Newman, J P

1998-02-01

Despite the growing popularity of computer imaging systems, it is not clear whether the medical and legal advantages of using such a system outweigh the disadvantages. The purpose of this report is to evaluate these aspects, and provide some protective guidelines in the use of computer imaging in cosmetic surgery. The positive and negative aspects of computer imaging from a medical and legal perspective are reviewed. Also, specific issues are examined by a legal panel. The greatest advantages are potential problem patient exclusion, and enhanced physician-patient communication. Disadvantages include cost, user learning curve, and potential liability. Careful use of computer imaging should actually reduce one's liability when all aspects are considered. Recommendations for such use and specific legal issues are discussed.

2013-01-01

There is a growing demand for off-the-shelf tissue engineered vascular grafts (TEVGs) for replacement or bypass of damaged arteries in various cardiovascular diseases. Scaffolds from the decellularized tissue skeletons to biopolymers and biodegradable synthetic polymers have been used for fabricating TEVGs. However, several issues have not yet been resolved, which include the inability to mimic the mechanical properties of native tissues, and the ability for long term patency and growth required for in vivo function. Electrospinning is a popular technique for the production of scaffolds that has the potential to address these issues. However, its application to human TEVGs has not yet been achieved. This review provides an overview of tubular scaffolds that have been prepared by electrospinning with potential for TEVG applications. PMID:23973391

U.S. Food System Working Conditions as an Issue of Food Safety.

PubMed

Clayton, Megan L; Smith, Katherine C; Pollack, Keshia M; Neff, Roni A; Rutkow, Lainie

2017-02-01

Food workers' health and hygiene are common pathways to foodborne disease outbreaks. Improving food system jobs is important to food safety because working conditions impact workers' health, hygiene, and safe food handling. Stakeholders from key industries have advanced working conditions as an issue of public safety in the United States. Yet, for the food industry, stakeholder engagement with this topic is seemingly limited. To understand this lack of action, we interviewed key informants from organizations recognized for their agenda-setting role on food-worker issues. Findings suggest that participants recognize the work standards/food safety connection, yet perceived barriers limit adoption of a food safety frame, including more pressing priorities (e.g., occupational safety); poor fit with organizational strategies and mission; and questionable utility, including potential negative consequences. Using these findings, we consider how public health advocates may connect food working conditions to food and public safety and elevate it to the public policy agenda.

2005-01-01

A new park is being considered for the confluence of the Los Angeles River and the Arroyo Seco in Los Angeles County, California. Components of the park development may include creation of a temporary lake on the Los Angeles River, removal of channel lining along part of the Arroyo Seco, restoration of native plants, creation of walking paths, and building of facilities such as a boat ramp and a visitor center. This report, prepared in cooperation with the Mountains Recreation and Conservancy Authority, delineates the geological, hydrological, and biological issues that may have an impact on the park development or result from development at the confluence, and identifies a set a tasks to help address these science issues. Geologic issues of concern relate to surface faulting, earthquake ground motions, liquefaction, landsliding, and induced seismicity. Hydrologic issues of concern relate to the hydraulics and water quality of both surface water and ground water. Biological issues of concern include colonization-extinction dynamics, wildlife corridors, wildlife reintroduction, non-native species, ecotoxicology, and restoration of local habitat and ecology. Potential tasks include (1) basic data collection and follow-up monitoring, and (2) statistical and probabilistic analyses and simulation modeling of the seismic, hydraulic, and ecological processes that may have the greatest impact on the park. The science issues and associated tasks delineated for the proposed confluence park will also have transfer value for river restoration in other urban settings.

Science education as a civil right: Urban schools and opportunity-to-learn considerations

2001-11-01

In this article I make the case that urban science education is a civil rights issue and that to effectively address it as such we must shift from arguments for civil rights as shared physical space in schools to demands for high-quality academic preparation that includes the opportunity to learn science. The argument is organized into two sections: first, a review of the school desegregation literature to make the case that urban science education for all is a civil rights issue; and second, an examination and critique of opportunity-to-learn literature, including an analysis of three opportunity-to-learn constructs to illustrate their potential as civil rights tools in science education.

The goal of this study was to develop and evaluate the impact of an aviation-style challenge and response sinus surgery-specific checklist on potential safety and equipment issues during sinus surgery at a tertiary academic health center. The secondary goal was to assess the potential impact of use of the checklist on surgical times during, before, and after surgery. This initiative is designed to be utilized in conjunction with the "standard" World Health Organization (WHO) surgical checklist. Although endoscopic sinus surgery is generally considered a safe procedure, avoidable complications and potential safety concerns continue to occur. The WHO surgical checklist does not directly address certain surgery-specific issues, which may be of particular relevance for endoscopic sinus surgery. This prospective observational pilot study monitored compliance with and compared the occurrence of safety and equipment issues before and after implementation of the checklist. Forty-seven consecutive endoscopic surgeries were audited; the first 8 without the checklist and the following 39 with the checklist. The checklist was compiled by evaluating the patient journey, utilizing the available literature, expert consensus, and finally reevaluation with audit type cases. The final checklist was developed with all relevant stakeholders involved in a Delphi method. Implementing this specific surgical checklist in 39 cases at our institution, allowed us to identify and rectify 35 separate instances of potentially unsafe, improper or inefficient preoperative setup. These incidents included issues with labeling of topical vasoconstrictor or injectable anesthetics (3, 7.7%) and availability, function and/or position of video monitors (2, 5.1%), endoscope (6, 15.4%), microdebrider (6, 15.4%), bipolar cautery (6, 15.4%), and suctions (12, 30.8%). The design and integration of this checklist for endoscopic sinus surgery, has helped improve efficiency and patient safety in the operating room setting. © 2018 ARS-AAOA, LLC.

The provision of neuropsychological services in rural/regional settings: professional and ethical issues.

PubMed

Allott, Kelly; Lloyd, Susan

2009-07-01

Despite rapid growth of the discipline of clinical neuropsychology during recent times, there is limited information regarding the identification and management of professional and ethical issues associated with the practice of neuropsychology within rural settings. The aim of this article is to outline the characteristics unique to practicing neuropsychology in rural communities and to describe the potential professional and ethical dilemmas that might arise. Issues are illustrated using examples from neuropsychological practice in a rural/regional setting in Victoria, Australia. Relative to urban regions, there is an inequality in the distribution of psychologists, including neuropsychologists, in rural areas. The unique characteristics of rural and regional communities that impact on neuropsychological practice are: 1) limited resources in expertise, technology, and community services, 2) greater travel distances and costs, 3) professional isolation, and 4) beliefs about psychological services. These characteristics lower the threshold for particular ethical issues. The ethical issues that require anticipation and careful management include: 1) professional competence, 2) multiple relationships, and 3) confidentiality. Through increased awareness and management of rural-specific professional and ethical issues, rural neuropsychologists can experience their work as rewarding and enjoyable. Specific guidelines for identifying, managing, and resolving ethically and professionally challenging situations that may arise during rural practice are provided.

Emerging Environmental Justice Issues in Nuclear Power and Radioactive Contamination

PubMed Central

Kyne, Dean; Bolin, Bob

2016-01-01

Nuclear hazards, linked to both U.S. weapons programs and civilian nuclear power, pose substantial environment justice issues. Nuclear power plant (NPP) reactors produce low-level ionizing radiation, high level nuclear waste, and are subject to catastrophic contamination events. Justice concerns include plant locations and the large potentially exposed populations, as well as issues in siting, nuclear safety, and barriers to public participation. Other justice issues relate to extensive contamination in the U.S. nuclear weapons complex, and the mining and processing industries that have supported it. To approach the topic, first we discuss distributional justice issues of NPP sites in the U.S. and related procedural injustices in siting, operation, and emergency preparedness. Then we discuss justice concerns involving the U.S. nuclear weapons complex and the ways that uranium mining, processing, and weapons development have affected those living downwind, including a substantial American Indian population. Next we examine the problem of high-level nuclear waste and the risk implications of the lack of secure long-term storage. The handling and deposition of toxic nuclear wastes pose new transgenerational justice issues of unprecedented duration, in comparison to any other industry. Finally, we discuss the persistent risks of nuclear technologies and renewable energy alternatives. PMID:27420080

Corrosion Considerations for Thermochemical Biomass Liquefaction Process Systems in Biofuel Production

NASA Astrophysics Data System (ADS)

Brady, M. P.; Keiser, J. R.; Leonard, D. N.; Whitmer, L.; Thomson, J. K.

2014-12-01

Thermochemical liquefaction processing of biomass to produce bio-derived fuels (e.g., gasoline, jet fuel, diesel, home heating oil, etc.) is of great recent interest as a renewable energy source. Approaches under investigation include direct liquefaction, hydrothermal liquefaction, hydropyrolysis, fast pyrolysis, etc., to produce energy dense liquids that can be utilized as produced or further processed to provide products of higher value. An issue with bio-oils is that they tend to contain significant concentrations of organic oxygenates, including acids, which make the bio-oil a potential source of corrosion issues in transport, storage, and use. Efforts devoted to modified/further processing of bio-oils to make them less corrosive are currently being widely pursued. Another issue that must also be addressed in bio-oil liquefaction is potential corrosion issues in the process equipment. Depending on the specific process, bio-oil liquefaction production temperatures are typically in the 300-600°C range, and the process environment can contain aggressive sulfur and halide species from both the biomass used and/or process additives. Detailed knowledge of the corrosion resistance of candidate process equipment alloys in these bio-oil production environments is currently lacking. This paper summarizes recent, ongoing efforts to assess the extent of corrosion of bio-oil process equipment, with the ultimate goal of providing a basis for the selection of the lowest cost alloy grades capable of providing the long-term corrosion resistance needed for future bio-oil production plants.

International adoption: a health and developmental prospective.

PubMed

Mason, Patrick; Narad, Christine

2005-02-01

Adoptions from international countries have become an option for many US families, with over 150,000 children adopted in the past 14 years. Typically, internationally adopted children present with a host of medical and developmental concerns. Issues such as growth stunting, abnormal behaviors, and significant delays in motor, speech, and language development are likely directly related to the prenatal and early postnatal environment experienced prior to adoption. The new family and its health-care team must quickly work to identify and address these issues to aid the child's integration into his or her new family. This article will examine potential issues seen in children who are being adopted, including the impact of early environment on subsequent development. We will summarize early and long-term medical issues and review the extent of developmental delays seen in children adopted internationally. Finally, we will discuss possible mechanisms leading to the observed delays, including the impact of stress on subsequent development. By understanding the extent of expected delays and the mechanisms likely causing the issues, the health-care team will be in a good position to quickly identify and develop intervention protocols that will foster the child's assimilation into his or her new family.

Argumentation in elementary science education: addressing methodological issues and conceptual understanding

NASA Astrophysics Data System (ADS)

Kaya, Ebru

2017-11-01

In this review essay I respond to issues raised in Mijung Kim and Wolff-Michael Roth's paper titled "Dialogical argumentation in elementary science classrooms", which presents a study dealing with dialogical argumentation in early elementary school classrooms. Since there is very limited research on lower primary school students' argumentation in school science, their paper makes a contribution to research on children's argumentation skills. In this response, I focus on two main issues to extend the discussion in Kim and Roth's paper: (a) methodological issues including conducting a quantitative study on children's argumentation levels and focusing on children's written argumentation in addition to their dialogical argumentation, and (b) investigating children's conceptual understanding along with their argumentation levels. Kim and Roth emphasize the difficulty in determining the level of children's argumentation through the Toulmin's Argument Pattern and lack of high level arguments by children due to their difficulties in writing texts. Regarding these methodological issues, I suggest designing quantitative research on coding children's argument levels because such research could potentially provide important findings on children's argumentation. Furthermore, I discuss alternative written products including posters, figures, or pictures generated by children in order to trace children's arguments, and finally articulating argumentation and conceptual understanding of children.

The right of children to have their voice heard has been accepted by researchers, and there are increasing numbers of qualitative health studies involving children. The ethical and methodological issues of including children in research have caused worldwide concerns, and many researchers have published articles sharing their own experiences. To systematically review and synthesise experts' opinions and experiences about ethical and methodological issues of including children in research, as well as related solution strategies. The research design was a systematic review of opinion-based evidence, based on the guidelines by Joanna Briggs Institute. A search of five computerised databases has been conducted in April 2014 and 2271 articles were found. After screening the titles, abstracts, full texts and appraising the quality, 30 articles were finally included in the review. A meta-aggregative approach was applied in the data analysis and synthesis process. Ethical approval is not needed as it is a systematic review of published literature. Six themes were identified, including evaluating potential risks and benefits, gaining access, obtaining informed consent/assent, protecting confidentiality and privacy, building rapport and collecting rich data. The similarities and differences between research involving children and that involving adults were indicated. All potential incentives should be justified when designing the study. Further studies need to research how to evaluate individual capacity of children and how to balance protecting children's right to participate and their interests in the research. Cultural differences related to researching children in different regions should also be studied. © The Author(s) 2014.

Dynamic Radioisotope Power System Development for Space Explorations

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

Qualls, A L

Dynamic power conversion offers the potential to produce radioisotope power systems (RPS) that generate higher power outputs and utilize the Pu-238 radioisotope more efficiently than Radioisotope Thermoelectric Generators (RTG). Additionally, dynamic systems also offer the potential of producing generators with significantly reduced power degradation over the course of deep space missions so that more power will be available at the end of the mission when it is needed for both powering the science and transmitting the results. The development of dynamic generators involves addressing technical issues not typically associated with traditional thermoelectric generators. Developing long-life, robust and reliable dynamic conversionmore » technology is challenging yet essential to building a suitable generator. Considerations include working within existing handling infrastructure where possible so that development costs can be kept low and integrating dynamic generators into spacecraft, which may be more complex than integration of static systems. Methods of interfacing to and controlling a dynamic generator must be considered and new potential failure modes must be taken into account. This paper will address some of the key issues of dynamic RPS design, development and adaption.Dynamic power conversion offers the potential to produce Radioisotope Power Systems (RPS) that generate higher power outputs and utilize the available heat source plutonium fuel more efficiently than Radioisotope Thermoelectric Generators.

2011-12-16

In today's era of energy crisis and global warming, hydrogen has been projected as a sustainable alternative to depleting CO(2)-emitting fossil fuels. However, its deployment as an energy source is impeded by many issues, one of the most important being storage. Chemical hydrogen storage materials, in particular B-N compounds such as ammonia borane, with a potential storage capacity of 19.6 wt % H(2) and 0.145 kg(H2)L(-1), have been intensively studied from the standpoint of addressing the storage issues. Ammonia borane undergoes dehydrogenation through hydrolysis at room temperature in the presence of a catalyst, but its practical implementation is hindered by several problems affecting all of the chemical compounds in the reaction scheme, including ammonia borane, water, borate byproducts, and hydrogen. In this Minireview, we exhaustively survey the state of the art, discuss the fundamental problems, and, where applicable, propose solutions with the prospect of technological applications.

The golden goose in the crosshairs: the transition to defined contribution pension plans in the public sector: unintended consequences.

PubMed

Johnson, Brian R

2013-01-01

State, county, and local governments are currently facing a myriad of economic issues, based on shrinking tax revenues combined with increased expenditures. Of these, the costs related to defined benefit pension plans are one of the most serious issues facing many public employers. Through a comprehensive review of the existing literature, this article examines how the shift from the defined benefit (DB) to defined contribution (DC) pension plan has the potential to enhance levels of labor unrest due to changes in union militancy, bargaining skills deficits, intra-organizational conflict, and issues related to economic trade-offs. Besides the capacity for immediate and deleterious ramifications in the collective bargaining process, the transition to the DC pension also presents some potentially negative consequences related to human resource management, including changes in the psychological contract, recruitment strategies, employee turnover, and changes in retirement patterns. Recommendations to improve labor relations and human resource management practices in the DC pension environment are also explored.

2013-06-01

Many papers have dealt with the political difficulties and ramifications of deep nuclear arms reductions, and the issues of “Going to Zero”. Political issues include extended deterrence, conventional weapons, ballistic missile defense, and regional and geo-political security issues. At each step on the road to low numbers, the verification required to ensure compliance of all parties will increase significantly. Looking post New START, the next step will likely include warhead limits in the neighborhood of 1000 . Further reductions will include stepping stones at1000 warheads, 100’s of warheads, and then 10’s of warheads before final elimination could be considered ofmore » the last few remaining warheads and weapons. This paper will focus on these three threshold reduction levels, 1000, 100’s, 10’s. For each, the issues and challenges will be discussed, potential solutions will be identified, and the verification technologies and chain of custody measures that address these solutions will be surveyed. It is important to note that many of the issues that need to be addressed have no current solution. In these cases, the paper will explore new or novel technologies that could be applied. These technologies will draw from the research and development that is ongoing throughout the national laboratory complex, and will look at technologies utilized in other areas of industry for their application to arms control verification.« less

A safer detection or sensing of toxic pollutants is one among several environmental contamination issues, across the globe. The ever-increasing industrial practices and controlled or uncontrolled release of toxic pollutants from various industrial sectors is a key source of this environmental problem. Significant research efforts have been or being made to tackle this problematic issue to fulfill the growing needs of the modern world. Despite many useful aspects, heavy metals are posing noteworthy toxicological concerns and human-health related issues at various levels of the ecosystem. In this context, notable efforts from various regulatory authorities, the increase in the concentration of these toxic heavy metals in the environment is of serious concern, so real-time monitoring is urgently required. Herein, we reviewed fluorescent sensor based models and their potentialities to address the detection fate of hazardous pollutants including chromium, manganese, cobalt, nickel, copper, and zinc as model elements. The novel aspects of turn-on/off fluorescent sensors have also been discussed from a state of the art viewpoint. In summary, comprehensive literature regarding fluorescent sensor based models and their potentialities to detect various types of toxic pollutants is reviewed. Copyright © 2018 Elsevier B.V.

Brunovskis, Anette; Surtees, Rebecca

2010-01-01

Recent discussions of trafficking research have included calls for more innovative studies and new methodologies in order to move beyond the current trafficking narrative, which is often based on unrepresentative samples and overly simplified images. While new methods can potentially play a role in expanding the knowledge base on trafficking, this article argues that the solution is not entirely about applying new methods, but as much about using current methods to greater effect and with careful attention to their limitations and ethical constraints. Drawing on the authors' experience in researching trafficking issues in a number of projects over the past decade, the article outlines and exemplifies some of the methodological and ethical issues to be considered and accommodated when conducting research with trafficked persons -- including unrepresentative samples; access to respondents; selection biases by "gatekeepers" and self selection by potential respondents. Such considerations should inform not only how research is undertaken but also how this information is read and understood. Moreover, many of these considerations equally apply when considering the application of new methods within this field. The article maintains that a better understanding of how these issues come into play and inform trafficking research will translate into tools for conducting improved research in this field and, by implication, new perspectives on human trafficking.

Ethical issues in microbicide clinical trials for HIV prevention.

PubMed

Gangestad, Angelina K; Salata, Robert A

2012-01-01

Women account for half of new infections with HIV annually. Heterosexual transmission is the most common route of infection in resource limited settings (RLS). An effective microbicide would help decrease transmission of HIV and potentially enable women to have more control in sexual relationships. Research into microbicides is done predominantly in RLS. In addition, there will be different issues and challenges to consider with respect to rectal microbicide use in men. There exist several ethical issues around microbicide development and clinical research which we explore in this review. Respect for persons, including autonomy and protection of vulnerable populations, beneficence, and justice are explored as they relate to microbicide research. Improving standards of care in RLS, trial design, and informed consent are discussed in more detail. Special populations including pregnant women, adolescents, and men who have sex with men are considered in more detail. A multipronged approach to HIV prevention will be necessary to have an impact on HIV prevention. A continued discussion around ethical issues in regard to study design, interpretation of results and implementation of compounds brought to market will remain critically important.

Media coverage of health issues and how to work more effectively with journalists: a qualitative study

PubMed Central

2010-01-01

Background The mass media has enormous potential to influence health-related behaviours and perceptions. Much research has focused on how the media frames health issues. This study sought to explore how journalists in Australia select and shape news on health issues. Methods The study involved semi-structured interviews with 16 journalists from major Australian print, radio and television media organisations reporting on avian influenza and pandemic planning. Journalists, including reporters, editors and producers, were interviewed between October 2006 and August 2007. Thematic analysis was used to draw out major lessons for health communicators. Results Journalists routinely attempted to balance different, sometimes competing, aims amidst significant operational constraints. They perceived the most trusted sources on health issues to be respected and independent doctors. Specialist health and medical reporters had a more sound technical knowledge, channels to appropriate sources, power within their organisations, and ability to advocate for better quality coverage. Conclusions An awareness of how to work with the media is essential for health communicators. This includes understanding journalists' daily routines, being available, providing resources, and building relationships with specialist health reporters. PMID:20822552

Methods for assessment of keel bone damage in poultry.

2015-10-01

Keel bone damage (KBD) is a critical issue facing the laying hen industry today as a result of the likely pain leading to compromised welfare and the potential for reduced productivity. Recent reports suggest that damage, while highly variable and likely dependent on a host of factors, extends to all systems (including battery cages, furnished cages, and non-cage systems), genetic lines, and management styles. Despite the extent of the problem, the research community remains uncertain as to the causes and influencing factors of KBD. Although progress has been made investigating these factors, the overall effort is hindered by several issues related to the assessment of KBD, including quality and variation in the methods used between research groups. These issues prevent effective comparison of studies, as well as difficulties in identifying the presence of damage leading to poor accuracy and reliability. The current manuscript seeks to resolve these issues by offering precise definitions for types of KBD, reviewing methods for assessment, and providing recommendations that can improve the accuracy and reliability of those assessments. © 2015 Poultry Science Association Inc.

Ethics Issues Arising in the Transition to Learning Health Care Systems: Results from Interviews with Leaders from 25 Health Systems.

Morain, Stephanie R; Kass, Nancy E

2016-01-01

There is increased interest in transitioning to a "learning health care system" (LHCS). While this transition brings the potential for significant benefits, it also presents several ethical considerations. Identifying the ethical issues faced by institutions in this transition is critical for realizing the goals of learning health care so that these issues can be anticipated and, where possible, resolved. 29 semi-structured telephone interviews were conducted with leaders within 25 health care institutions. Respondents were recruiting using purposive sampling, targeting institutions considered as LHCS leaders. All interviews were audiorecorded and transcribed. NVIVO10 software was used to support qualitative analysis. Respondents described seven ethical challenges: (1) ethical oversight of learning activities; (2) transparency of learning activities to patients; (3) potential tensions between improving quality and reducing costs; (4) data sharing and data management; (5) lag time between discovery and implementation; (6) transparency to patients about quality; and (7) randomization for quality improvement initiatives. To move towards LHCS, several ethical considerations require further attention, including: the continued appropriateness of the research-treatment distinction; policy frameworks for privacy and data sharing; informing patients about learning activities; obligations to share data on quality; and the potential for trade-offs between quality improvement and cost control. To our knowledge, this is the first project to ask leaders from health care systems committed to ongoing learning about the ethical issues they have faced in this effort. Their experiences can provide guidance on relevant ethical issues, and what might be done to resolve them.

Did I Tell You That? Ethical Issues Related to Using Computational Methods to Discover Non-Disclosed Patient Characteristics.

PubMed

Cato, Kenrick D; Bockting, Walter; Larson, Elaine

2016-07-01

Widespread availability of electronic health records coupled with sophisticated statistical methods offer great potential for a variety of applications for health and disease surveillance, developing predictive models and advancing decision support for clinicians. However, use of "big data" mining and discovery techniques has also raised ethical issues such as how to balance privacy and autonomy with the wider public benefits of data sharing. Furthermore, electronic data are being increasingly used to identify individual characteristics, which can be useful for clinical prediction and management, but were not previously disclosed to a clinician. This process in computer parlance is called electronic phenotyping, and has a number of ethical implications. Using the Belmont Report's principles of respect for persons, beneficence, and justice as a framework, we examined the ethical issues posed by electronic phenotyping. Ethical issues identified include the ability of the patient to consent for the use of their information, the ability to suppress pediatric information, ensuring that the potential benefits justify the risks of harm to patients, and acknowledging that the clinician's biases or stereotypes, conscious or unintended, may become a factor in the therapeutic interaction. We illustrate these issues with two vignettes, using the person characteristic of gender minority status (i.e., transgender identity) and health history characteristic of substance abuse. Data mining has the potential to uncover patient characteristics previously obscured, which can provide clinicians with beneficial clinical information. Hence, ethical guidelines must be updated to ensure that electronic phenotyping supports the principles of respect for persons, beneficence, and justice. © The Author(s) 2016.

LePoire, D. J.; Glenn, J. C.; Environmental Assessment

2007-02-01

In the application of new technologies that address the terrorism problem, an objective is to ensure that the technology does not cause more problems than it solves. Potential new technologies, including convergences of genomics, robotics, information technology, and nanotechnology, might rapidly develop. As with any technological advance, each of these offers a mixture of benefits and risks. At first, a direct approach is reviewed by looking at how these technologies might deter the motive, means, and opportunity for terrorist activities. While there are many potential deterrence applications, other issues are identified that might cause unintended problems in the system. Somemore » of these problems include the possible contribution to terrorist motives by increasing stresses toward divisiveness in society, terrorist means through the development of dual-use technologies, or terrorist opportunities by further developing technological vulnerabilities. Next, a more systemic approach is taken by reviewing a wider range of issues, such as resource availability, management of science and technology, and general societal trends. The balance between technological change and social response is important in realizing benefits while mitigating unintended consequences such as harmful uses through terrorist actions. To explore issues concerning this balance, possible technological development scenarios are reviewed, including the possibility of accelerating or slowing technological development. Some recent recommendations are considered within this context. The need for a balance between technological and social response in this asymmetric situation suggests that the benefits of a rapid technological response against terrorism might not be as large as those observed during World War II.« less

Collaborative Paradigm of Preventive, Personalized, and Precision Medicine With Point-of-Care Technologies

PubMed Central

2016-01-01

Recent advances in biosensors, medical instrumentation, and information processing and communication technologies (ICT) have enabled significant improvements in healthcare. However, these technologies have been mainly applied in clinical environments, such as hospitals and healthcare facilities, under managed care by well-trained and specialized individuals. The global challenge of providing quality healthcare at affordable cost leads to the proposed paradigm of P reventive, Personalized, and Precision Medicine that requires a seamless use of technology and infrastructure support for patients and healthcare providers at point-of-care (POC) locations including homes, semi or pre-clinical facilities, and hospitals. The complexity of the global healthcare challenge necessitates strong collaborative interdisciplinary synergies involving all stakeholder groups including academia, federal research institutions, industry, regulatory agencies, and clinical communities. It is critical to evolve with collaborative efforts on the translation of research to technology development toward clinical validation and potential healthcare applications. This special issue is focused on technology innovation and translational research for POC applications with potential impact in improving global healthcare in the respective areas. Some of these papers were presented at the NIH-IEEE Strategic Conference on Healthcare Innovations and POC Technologies for Precision Medicine (HI-POCT) held at the NIH on November 9–10, 2015. The papers included in the Special Issue provide a spectrum of critical issues and collaborative resources on translational research of advanced POC devices and ICT into global healthcare environment.

2015-10-01

Since their ubiquity in the ocean and marine organisms was first revealed, global concern about microplastics has grown considerably. The North Pacific Ocean and the adjacent marginal seas have high levels of microplastic contamination compared with the global average. This special issue on microplastics was organized by the North Pacific Marine Science Organization to share information on microplastic pollution in the North Pacific region. The special issue highlights high levels of contamination in the North Pacific both on shorelines and at the sea surface. Particularly high levels of contamination were reported on the western and southern coasts of Korea. Sources, including sewage discharge, aquaculture, and shipyards, were implicated. With the direction and energy of surface winds and currents have an important influence on shoreline patterns of distribution. The special issue also demonstrates potential for ingestion of microplastic by small planktonic organisms at the base of the food chain. A wide range of chemicals are associated with plastic debris and concerns are expressed about the potential for these chemicals to transfer to biota upon ingestion. As an introduction to the topic, this paper provides a brief background on microplastic contamination, highlights some key research gaps, and summarizes findings from the articles published in this issue.

Internet Cancer Support Groups (ICSGs) are an emerging form of support group on Internet specifically for cancer patients. Previous studies have indicated the effectiveness of ICSGs as a research setting or a data-collection method. Yet recent studies have also indicated that ICSGs tend to serve highly educated, high-income White males who tend to be at an early stage of cancer. In this article, a total of 317 general ICSGs and 229 ethnic-specific ICSGs searched through Google.com, Yahoo.com, http://Msn.com, AOL.com, and ACOR.org are analyzed from a feminist perspective. The written records of group discussions and written memos by the research staff members were also analyzed using content analysis. The idea categories that emerged about these groups include (a) authenticity issues; (b) ethnicity and gender issues; (c) intersubjectivity issues; and (d) potential ethical issues. The findings suggest that (a) researchers adopt multiple recruitment strategies through various Internet sites and/or real settings; (b) researchers raise their own awareness of the potential influences of the health-related resources provided by ICSGs and regularly update their knowledge related to the federal and state standards and/or policies related to ICSGs; and (c) researchers consider adopting a quota-sampling method.

Dental tourism is patients travelling across international borders with the intention of receiving dental care. It is a growing phenomenon that raises many ethical issues, particularly regarding the dentist-patient relationship. We discuss various issues related to this phenomenon, including patient autonomy over practitioner choice, patient safety, continuity of care, informed consent and doctor-patient communication, among other factors. In particular, patients partaking in medical tourism should be informed of its potential problems and the importance of proper planning and post-treatment care to guarantee high-quality treatment outcomes.

To characterize the prevalence of health-related housing quality exposure for the vulnerable populations that live in affordable housing. Retrospective cross-sectional study. Affordable housing properties in Ohio inspected between 2007 and 2011. Stratified random sample of physical inspection reports (n = 370), including a case study of properties receiving multiple inspections (n = 35). Health-related housing factors, including mold, fire hazard, and others. The majority of affordable housing property inspections (85.1%) included at least 1 health-related housing quality issue. The prevalence of specific health-related violations was varied, with appliance and plumbing issues being the most common, followed by fire, mold, and pest violations. Across funding agencies, the actual implementation of inspection protocols differed. The majority of physical inspections identified housing quality issues that have the potential to impact human health. If the frequency of physical inspections is reduced as a result of inspection alignment, the most health protective inspection protocol should be selected for funding agency inspections; a standardized physical inspection tool is recommended to improve the consistency of inspection findings between mandatory physical inspections in order to promote optimum tenant health.

Boyce, P; Mason, C

1996-02-01

A number of personality styles have been proposed as vulnerability traits to depression. In this paper methodological problems associated with identifying such traits are discussed. These include state effects contaminating personality scales and the issue of depressive heterogeneity. Potential depression-prone personality traits are then discussed, including obsessionality, neuroticism, dependency and cognitive dysfunction. High interpersonal sensitivity as a risk factor to depression is then discussed.

In 2003 and 2013, the World Health Organization convened informal consultations on characterization and quality aspects of vaccines based on live virus vectors. In the resulting reports, one of several issues raised for future study was the potential for recombination of virus-vectored vaccines with wild type pathogenic virus strains. This paper presents an assessment of this issue formulated by the Brighton Collaboration. To provide an appropriate context for understanding the potential for recombination of virus-vectored vaccines, we review briefly the current status of virus vectored vaccines, mechanisms of recombination between viruses, experience with recombination involving live attenuated vaccines in the field, and concerns raised previously in the literature regarding recombination of virus-vectored vaccines with wild type virus strains. We then present a discussion of the major variables that could influence recombination between a virus-vectored vaccine and circulating wild type virus and the consequences of such recombination, including intrinsic recombination properties of the parent virus used as a vector; sequence relatedness of vector and wild virus; virus host range, pathogenesis and transmission; replication competency of vector in target host; mechanism of vector attenuation; additional factors potentially affecting virulence; and circulation of multiple recombinant vectors in the same target population. Finally, we present some guiding principles for vector design and testing intended to anticipate and mitigate the potential for and consequences of recombination of virus-vectored vaccines with wild type pathogenic virus strains.

Cooke, Megan E; Meyers, Jacquelyn L; Latvala, Antti; Korhonen, Tellervo; Rose, Richard J; Kaprio, Jaakko; Salvatore, Jessica E; Dick, Danielle M

2015-10-01

The purpose of this study was to address two methodological issues that have called into question whether previously reported gene-environment interaction (GxE) effects for adolescent alcohol use are 'real'. These issues are (1) the potential correlation between the environmental moderator and the outcome across twins and (2) non-linear transformations of the behavioral outcome. Three environments that have been previously studied (peer deviance, parental knowledge, and potentially stressful life events) were examined here. For each moderator (peer deviance, parental knowledge, and potentially stressful life events), a series of models was fit to both a raw and transformed measure of monthly adolescent alcohol use in a sample that included 825 dizygotic (DZ) and 803 monozygotic (MZ) twin pairs. The results showed that the moderating effect of peer deviance was robust to transformation, and that although the significance of moderating effects of parental knowledge and potentially stressful life events were dependent on the scale of the adolescent alcohol use outcome, the overall results were consistent across transformation. In addition, the findings did not vary across statistical models. The consistency of the peer deviance results and the shift of the parental knowledge and potentially stressful life events results between trending and significant, shed some light on why previous findings for certain moderators have been inconsistent and emphasize the importance of considering both methodological issues and previous findings when conducting and interpreting GxE analyses.

Dual-Energy CT: New Horizon in Medical Imaging

PubMed Central

Goo, Jin Mo

2017-01-01

Dual-energy CT has remained underutilized over the past decade probably due to a cumbersome workflow issue and current technical limitations. Clinical radiologists should be made aware of the potential clinical benefits of dual-energy CT over single-energy CT. To accomplish this aim, the basic principle, current acquisition methods with advantages and disadvantages, and various material-specific imaging methods as clinical applications of dual-energy CT should be addressed in detail. Current dual-energy CT acquisition methods include dual tubes with or without beam filtration, rapid voltage switching, dual-layer detector, split filter technique, and sequential scanning. Dual-energy material-specific imaging methods include virtual monoenergetic or monochromatic imaging, effective atomic number map, virtual non-contrast or unenhanced imaging, virtual non-calcium imaging, iodine map, inhaled xenon map, uric acid imaging, automatic bone removal, and lung vessels analysis. In this review, we focus on dual-energy CT imaging including related issues of radiation exposure to patients, scanning and post-processing options, and potential clinical benefits mainly to improve the understanding of clinical radiologists and thus, expand the clinical use of dual-energy CT; in addition, we briefly describe the current technical limitations of dual-energy CT and the current developments of photon-counting detector.

Preclinical Development of Cell-Based Products: a European Regulatory Science Perspective.

PubMed

McBlane, James W; Phul, Parvinder; Sharpe, Michaela

2018-06-25

This article describes preclinical development of cell-based medicinal products for European markets and discusses European regulatory mechanisms open to developers to aid successful product development. Cell-based medicinal products are diverse, including cells that are autologous or allogeneic, have been genetically modified, or not, or expanded ex vivo, and applied systemically or to an anatomical site different to that of their origin; comments applicable to one product may not be applicable to others, so bespoke development is needed, for all elements - quality, preclinical and clinical. After establishing how the product is produced, proof of potential for therapeutic efficacy, and then safety, of the product need to be determined. This includes understanding biodistribution, persistence and toxicity, including potential for malignant transformation. These elements need to be considered in the context of the intended clinical development. This article describes regulatory mechanisms available to developers to support product development that aim to resolve scientific issues prior to marketing authorization application, to enable patients to have faster access to the product than would otherwise be the case. Developers are encouraged to be aware of both the scientific issues and regulatory mechanisms to ensure patients can be supplied with these products.

Opportunities at the Intersection of Bioinformatics and Health Informatics

PubMed Central

Miller, Perry L.

2000-01-01

This paper provides a “viewpoint discussion” based on a presentation made to the 2000 Symposium of the American College of Medical Informatics. It discusses potential opportunities for researchers in health informatics to become involved in the rapidly growing field of bioinformatics, using the activities of the Yale Center for Medical Informatics as a case study. One set of opportunities occurs where bioinformatics research itself intersects with the clinical world. Examples include the correlations between individual genetic variation with clinical risk factors, disease presentation, and differential response to treatment; and the implications of including genetic test results in the patient record, which raises clinical decision support issues as well as legal and ethical issues. A second set of opportunities occurs where bioinformatics research can benefit from the technologic expertise and approaches that informaticians have used extensively in the clinical arena. Examples include database organization and knowledge representation, data mining, and modeling and simulation. Microarray technology is discussed as a specific potential area for collaboration. Related questions concern how best to establish collaborations with bioscientists so that the interests and needs of both sets of researchers can be met in a synergistic fashion, and the most appropriate home for bioinformatics in an academic medical center.

Ethics and the cardiac pacemaker: more than just end-of-life issues.

PubMed

Hutchison, Katrina; Sparrow, Robert

2018-05-01

For many years, ethical debate about pacemakers has focused on whether and under what circumstances they may be turned off in end of life care. Several other important ethical issues have been neglected, perhaps because the dilemmas they pose for cardiologists are not so immediate. These include: potential conflicts of interest, particularly those arising from the role of industry employed allied professionals (IEAPs) in pacemaker care; unanticipated impacts of commercial competition and the device improvement cycle; risks associated with remotely accessible software; equity in access to healthcare; and questions about reuse of explanted pacemakers in low and middle income countries. This paper analyses these issues in order to facilitate a more comprehensive approach to ethics and the cardiac pacemaker. Cardiologists should be aware of all of these issues and contribute to ongoing discussions about how they are resolved.

Assessment of Adolescent Neurotoxicity: Rationale and Methodological Considerations

PubMed Central

Spear, Linda Patia

2007-01-01

This introduction to the special issue of Neurotoxicology and Teratology on “Risk of neurobehavioral toxicity in adolescence” begins by broadly considering the ontogeny and phylogeny of adolescence, and the potential value of animal models of adolescence. Major findings from the emerging neuroscience of adolescence are then highlighted to establish the importance of studies of adolescent neurotoxicity. A variety of methodological issues that are of particular relevance to adolescent exposures are then discussed. These include consideration of pharmacokinetic factors, inclusion of other-aged comparison group(s), and issues involving timing, route of administration, and exposure-induced alterations in growth rate. Despite such methodological challenges, research to determine whether adolescence is a time of increased vulnerability (or greater resiliency) to specific drugs and environmental toxicants is progressing rapidly, as exemplified by the work presented in the articles of this special issue.

The Ethics of Clinical Trials Research in Severe Mood Disorders.

Nugent, Allison C; Miller, Franklin G; Henter, Ioline D; Zarate, Carlos A

2017-07-01

Mood disorders, including major depressive disorder (MDD) and bipolar disorder (BD), are highly prevalent, frequently disabling, and sometimes deadly. Additional research and more effective medications are desperately needed, but clinical trials research in mood disorders is fraught with ethical issues. Although many authors have discussed these issues, most do so from a theoretical viewpoint. This manuscript uses available empirical data to inform a discussion of the primary ethical issues raised in mood disorders research. These include issues of consent and decision-making capacity, including patients' motivations for participating in research. We also address drug withdrawals, placebo controls, and the overall safety of research. Finally, we examine the extant literature for studies discussing potential indirect benefits of clinical trials research to participants. Taken together, the evidence suggests that clinical trials research incorporating drug withdrawals and placebo controls can be conducted safely and ethically, even in patients with severe or treatment-resistant mood disorders. In fact, given the dearth of effective treatment options for this population, it is our opinion that a moral imperative exists to extend the offer of research participation to severely ill or treatment-resistant groups. Published 2017. This article is a U.S. Government work and is in the public domain in the USA.

Preferred drug lists: potential impact on healthcare economics.

PubMed

Ovsag, Kimberly; Hydery, Sabrina; Mousa, Shaker A

2008-01-01

To analyze the implementation of Medicaid preferred drug lists (PDLs) in a number of states and determine its impact on quality of care and cost relative to other segments of healthcare. We reviewed research and case studies found by searching library databases, primarily MEDLINE and EBSCOHost, and searching pertinent journals. Keywords initially included "drug lists," "prior authorization," "prior approval," and "Medicaid." We added terms such as "influence use of other healthcare services," "quality of care," and "overall economic impact." We mainly used primary sources. Based on our literature review, we determined that there are a number of issues regarding Medicaid PDLs that need to be addressed. Some issues include: (a) the potential for PDLs to influence the utilization of other healthcare services, (b) criteria used by Medicaid for determining acceptance of drugs onto a PDL, (c) the effect of PDL implementation on compliance to new regimens, (d) the potential effects of restricting medication availability on quality of care, (e) administrative costs associated with PDLs, and (f) satisfaction rates among patients and medical providers. This review highlighted expected short-term cost savings with limited degree of compromised quality of PDL implementation, but raised the concern about the potential long-term decline in quality of care and overall economic impact. The number of concerns raised indicates that further studies are warranted regarding both short-term cost benefits as well as potential long-term effects of Medicaid PDL implementation. Objective analysis of these effects is necessary to ensure cost-effectiveness and quality of care.

This tutorial highlights some issues in the experimental design of clinical 'omics biomarker discovery, how to avoid bias and get as true quantities as possible from biochemical analyses, and how to select samples to improve the chance of answering the clinical question at issue. This includes the importance of defining clinical aim and end point, knowing the variability in the results, randomization of samples, sample size, statistical power, and how to avoid confounding factors by including clinical data in the sample selection, that is, how to avoid unpleasant surprises at the point of statistical analysis. The aim of this Tutorial is to help translational clinical and preclinical biomarker candidate research and to improve the validity and potential of future biomarker candidate findings.

The evaluation of the National Long Term Care Demonstration. 2. Estimation methodology.

PubMed Central

Brown, R S

1988-01-01

Channeling effects were estimated by comparing the post-application experience of the treatment and control groups using multiple regression. A variety of potential threats to the validity of the results, including sample composition issues, data issues, and estimation issues, were identified and assessed. Of all the potential problems examined, the only one determined to be likely to cause widespread distortion of program impact estimates was noncomparability of the baseline data. To avoid this distortion, baseline variables judged to be noncomparably measured were excluded from use as control variables in the regression equation. (Where they existed, screen counterparts to these noncomparable baseline variables were used as substitutes.) All of the other potential problems with the sample, data, or regression estimation approach were found to have little or no actual effect on impact estimates or their interpretation. Broad implementation of special procedures, therefore, was not necessary. The study did find that, because of the frequent use of proxy respondents, the estimated effects of channeling on clients' well-being actually may reflect impacts on the well-being of the informal caregiver rather than the client. This and other isolated cases in which there was some evidence of a potential problem for specific outcome variables were identified and examined in detail in technical reports dealing with those outcomes. Where appropriate, alternative estimates were presented. PMID:3130329

Direct-to-consumer online genetic testing and the four principles: an analysis of the ethical issues.

PubMed

Wasson, Katherine; Cook, E David; Helzlsouer, Kathy

2006-01-01

The development of genetic tests marketed and sold direct-to-consumers (DTC) via the internet raises moral concerns and debate about their appropriateness and ethical and clinical significance. These tests are offered for a wide range of diseases and conditions, and the mutations have variable penetrance and associated risk. A number of these tests lack data on their accuracy and reliability, making interpretation of results difficult. DTC genetic testing is undertaken outside the context of the physician-patient relationship and may lack appropriate individual and family genetic counseling, leaving the consumer vulnerable to potential harms, such as misinterpretation of results, including false positive or false reassurance, with limited or no benefits. Beauchamp and Childress's four principles of biomedical ethics provide a framework for analyzing the ethical issues raised by DTC genetic testing. We argue that the potential harms outweigh the potential benefits of such tests, that respect for autonomy should be limited in light of potential harm from DTC testing, and that the availability of genetic testing over the internet may be considered unfair and unjust and affect resource allocation by placing an unfair burden on primary care physicians. In light of the moral issues posed by these tests, practical responses are suggested in the areas of consumer education, medical education, and interaction with commercial companies.

A review on remote monitoring technology applied to implantable electronic cardiovascular devices.

PubMed

Costa, Paulo Dias; Rodrigues, Pedro Pereira; Reis, António Hipólito; Costa-Pereira, Altamiro

2010-12-01

Implantable electronic cardiovascular devices (IECD) include a broad spectrum of devices that have the ability to maintain rhythm, provide cardiac resynchronization therapy, and/or prevent sudden cardiac death. The incidence of bradyarrhythmias and other cardiac problems led to a broader use of IECD, which turned traditional follow-up into an extremely heavy burden for healthcare systems to support. Our aim was to assess the impact of remote monitoring on the follow-up of patients with IECD. We performed a review through PubMed using a specific query. The paper selection process included a three-step approach in which title, abstract, and cross-references were analyzed. Studies were then selected using previously defined inclusion criteria and analyzed according to the country of origin of the study, year, and journal of publication; type of study; and main issues covered. Twenty articles were included in this review. Eighty percent of the selected papers addressed clinical issues, from which 94% referred clinical events identification, clinical stability, time savings, or physician satisfaction as advantages, whereas 38% referred disadvantages that included both legal and technical issues. Forty-five percent of the papers referred patient issues, from which 89% presented advantages, focusing on patient acceptance/satisfaction, and patient time-savings. The main downsides were technical issues but patient privacy was also addressed. All the papers dealing with economic issues (20%) referred both advantages and disadvantages equally. Remote monitoring is presently a safe technology, widely accepted by patients and physicians, for its convenience, reassurance, and diagnostic potential. This review summarizes the principles of remote IECD monitoring presenting the current state-of-the-art. Patient safety and device interaction, applicability of current technology, and limitations of remote IECD monitoring are also addressed. The use of remote monitor should consider the selection of patients, the type of disease, and centers' availability to receive, interpret and respond to device alerts. Before remote IECD monitoring can be routinely used, technical, procedure, and ethical/legal issues should be addressed.

Therapeutic Applications of Extracellular Vesicles: Clinical Promise and Open Questions

PubMed Central

Breakefield, Xandra O.; Leonard, Joshua N.

2015-01-01

This review provides an updated perspective on rapidly proliferating efforts to harness extracellular vesicles (EVs) for therapeutic applications. We summarize current knowledge, emerging strategies, and open questions pertaining to clinical potential and translation. Potentially useful EVs comprise diverse products of various cell types and species. EV components may also be combined with liposomes and nanoparticles to facilitate manufacturing as well as product safety and evaluation. Potential therapeutic cargoes include RNA, proteins, and drugs. Strategic issues considered herein include choice of therapeutic agent, means of loading cargoes into EVs, promotion of EV stability, tissue targeting, and functional delivery of cargo to recipient cells. Some applications may harness natural EV properties, such as immune modulation, regeneration promotion, and pathogen suppression. These properties can be enhanced or customized to enable a wide range of therapeutic applications, including vaccination, improvement of pregnancy outcome, and treatment of autoimmune disease, cancer, and tissue injury.

Ethical Considerations Regarding the Use of Smart Home Technologies for Older Adults: An Integrative Review.

PubMed

Chung, Jane; Demiris, George; Thompson, Hilaire J

2016-01-01

With the wide adoption and use of smart home applications, there is a need for examining ethical issues regarding smart home use at the intersection of aging, technology, and home environment. The purpose of this review is to provide an overview of ethical considerations and the evidence on these ethical issues based on an integrative literature review with regard to the utilization of smart home technologies by older adults and their family members. REVIEW DESIGN AND METHODS: We conducted an integrative literature review of the scientific literature from indexed databases (e. g., MEDLINE, CINAHL, and PsycINFO). The framework guiding this review is derived from previous work on ethical considerations related to telehealth use for older adults and smart homes for palliative care. Key ethical issues of the framework include privacy, informed consent, autonomy, obtrusiveness, equal access, reduction in human touch, and usability. Six hundred and thirty-five candidate articles were identified between the years 1990 and 2014. Sixteen articles were included in the review. Privacy and obtrusiveness issues appear to be the most important factors that can affect smart home technology adoption. In addition, this article recommends that stigmatization and reliability and maintenance of the system are additional factors to consider. When smart home technology is used appropriately, it has the potential to improve quality of life and maintain safety among older adults, ultimately supporting the desire of older adults for aging in place. The ability to respond to potential ethical concerns will be critical to the future development and application of smart home technologies that aim to enhance safety and independence.

Fertility and pregnancy-related issues represent one of the main areas of concerns for young women with breast cancer. Carrying a germline deleterious BRCA mutation adds additional burden on this regard due to the specific issues that should be considered during the oncofertility counseling of this special patient group. Despite the availability of a growing amount of data in the general breast cancer population on the feasibility and safety of fertility preservation and pregnancy after diagnosis, numerous challenges remain for BRCA-mutated breast cancer patients in whom very limited studies have been performed so far. Therefore, studies aiming to address the specific issues of these patients, including the impact of the mutation on their fertility potential, the safety and efficacy of the different strategies for fertility preservation, and the feasibility of having a pregnancy after diagnosis, should be considered a research priority. The aim of the present manuscript is to perform an in depth overview on the role of BRCA mutations in breast cancer with a specific focus on their impact on reproductive potential, and to discuss the fertility and pregnancy issues faced by BRCA-mutated breast cancer patients. The final goal of this manuscript is to highlight current and upcoming knowledge in this field for trying to help physicians dealing with these patients during oncofertility counseling.

This is our ninth annual horizon scan to identify emerging issues that we believe could affect global biological diversity, natural capital and ecosystem services, and conservation efforts. Our diverse and international team, with expertise in horizon scanning, science communication, as well as conservation science, practice, and policy, reviewed 117 potential issues. We identified the 15 that may have the greatest positive or negative effects but are not yet well recognised by the global conservation community. Themes among these topics include new mechanisms driving the emergence and geographic expansion of diseases, innovative biotechnologies, reassessments of global change, and the development of strategic infrastructure to facilitate global economic priorities.

Cancer of the lung and bronchus is the leading fatal malignancy in the United States. Five-year survival is low, but treatment of early stage disease considerably improves chances of survival. Advances in multidetector-row computed tomography technology provide detection of smaller lung nodules and offer a potentially effective screening tool. The large number of images per exam, however, requires considerable radiologist time for interpretation and is an impediment to clinical throughput. Thus, computer-aided diagnosis (CAD) methods are needed to assist radiologists with their decision making. To promote the development of CAD methods, the National Cancer Institute formed the Lung Image Database Consortium (LIDC). The LIDC is charged with developing the consensus and standards necessary to create an image database of multidetector-row computed tomography lung images as a resource for CAD researchers. To develop such a prospective database, its potential uses must be anticipated. The ultimate applications will influence the information that must be included along with the images, the relevant measures of algorithm performance, and the number of required images. In this article we outline assessment methodologies and statistical issues as they relate to several potential uses of the LIDC database. We review methods for performance assessment and discuss issues of defining "truth" as well as the complications that arise when truth information is not available. We also discuss issues about sizing and populating a database.

Ethical Issues Raised by Private Practice Physiotherapy Are More Diverse than First Meets the Eye: Recommendations from a Literature Review

Drolet, Marie-Josée; Williams-Jones, Bryn

2015-01-01

ABSTRACT Purpose: Physiotherapy in private practice differs from physiotherapy practised in a public setting in several ways, the most evident of which is the for-profit nature of private physiotherapy clinics; these differences can generate distinct and challenging ethical issues. The objectives of this article are to identify ethical issues encountered by physiotherapists in private practice settings and to identify potential solutions and recommendations to address these issues. Method: After a literature search of eight databases, 39 studies addressing ethical issues in a private practice context were analyzed. Results: A total of 25 ethical issues emerging from the included studies were classified into three main categories: (1) business and economic issues (e.g., conflicts of interests, inequity in a managed care context, lack of time affecting quality of care); (2) professional issues (e.g., professional autonomy, clinical judgment, treatment effectiveness, professional conduct); and (3) patients' rights and welfare issues (e.g., confidentiality, power asymmetries, paternalism vs. patient autonomy, informed consent). Recommendations as to how physiotherapists could better manage these issues were then identified and categorized. Conclusions: The physiotherapy community should reflect on the challenges raised by private practice so that professionals can be supported—through education, research, and good governance—in providing the best possible care for their patients.

2018-01-01

Rotavirus vaccines have demonstrated significant impact in reducing the burden of morbidity and mortality from childhood diarrhoea in countries that have implemented routine vaccination to date. Despite this success, in many countries, rotavirus vaccine coverage remains lower than that of other routine childhood vaccines. Several issues may potentially affect vaccine uptake, namely safety concerns related to intussusception with consequent age restrictions on rotavirus vaccination, contamination with porcine circovirus, vaccine-derived reassortant strains and hospitalization in newborn nurseries at time of administration of live oral rotavirus vaccine. In addition to these safety concerns, other factors may also affect uptake, including lower vaccine efficacy in the developing world, potential emergence of strains escaping from vaccine protection resulting in lower overall impact of a vaccination programme and sustainable vaccine financing. Although further work is needed to address some of these concerns, global policy bodies have reaffirmed that the benefits of rotavirus vaccination outweigh the risks, and vaccine use is recommended globally.

Examining the Role of Mental Health and Clinical Issues within Talent Development

Hill, Andy; MacNamara, Áine; Collins, Dave; Rodgers, Sheelagh

2016-01-01

Although significant research supports the association between physical activity and mental wellbeing, current literature acknowledges that athletes are no less susceptible to mental illness than the general population. Despite welcomed initiatives aimed at improving mental health within elite sport, these programs often fail to target young athletes; an important concern given that the genesis of many mental illnesses are recognized to occur during this critical period. Given the importance of early intervention and effective treatment, and the potentially devastating consequences of clinical issues going undiagnosed, the implications for talent identification and development (TID) become obvious. With this in mind, this study sought to examine the range of mental health issues that may impact upon developing athletes and potential consequences for the development process, specific risk and protective factors associated with talent development, along with an examination of current practices concerning the identification of mental health issues in such environments. Qualitative interviews were conducted with purposively sampled clinicians (n = 8) experienced in working with adolescents and/or young athletes. Inductive content analysis was undertaken, identifying four main themes: key behavioral indicators; associated risk factors; associated protective factors; and issues around identification and diagnosis. Key behavioral indicators included behavioral change, along with behaviors associated with eating disorders, anxiety and depression. Risk factors centered on family background, the performance environment, and issues surrounding adolescence. Protective factors were primarily social in nature. Finally, a lack of awareness and understanding of clinical issues, multiple causes of symptoms, non-disclosure and the need for triangulation of assessment were identified. The need for improved identification and intervention strategies was apparent, with coaches identified as well placed to detect general “warning signs” such as behavioral change. Short of integrating trained clinicians into talent development environments, as part of a triangulation process, ecologically validated assessment tools—coupled with appropriate training and signposting—could offer a practical way of flagging potential issues in developing athletes. The need for the development of such an instrument is therefore apparent. Finally, education around the influential role of family is also recommended in order to promote the protective elements and mitigate risk factors. PMID:26793153

Definition of key concepts; review of health personalisation, emergent health information and communication technologies and knowledge sources available to citizens and social media; and identification of unresolved issues threatening optimal use of each. A structured review supported by citations and examples. Several new aspects of consumer health informatics are emerging, including new knowledge sources, feedback on treatments and care providers, on-line videos, and a new generation of patient experience sites including those which are for profit and seek to influence treatment paradigms. Not just the information usage, but also the potential social challenges and malicious abuses, are global issues, and also transcend the traditional health community and thus should be addressed in partnership with other global agencies.

California Tribal Nations Technical Water Research

2005-08-15

This research focused on identifying the key technical water issues of federally recognized California Native American tribes, the context within which these water issues arise for the tribes, and an appropriate format for potentially opening further dialogue on water research issues between the tribes and Lawrence Livermore National Laboratory (LLNL) scientists. At LLNL, a Water Quality and Resource Management Issues Workshop held in January of 2003 resulted in multiple recommendations, one proposing a LLNL dialogue with California tribes to further inform LLNL's prioritization of water issues based on identified needs across national sectors. The focus of this aforementioned Water Qualitymore » and Resource Management Issues Workshop was to identify national and international priority water research issues with which LLNL may align their research efforts and contribute to resolving these needs. LLNL staff researched various sectors to delineate the key water issues associated with each. This preliminary water issue research included diverse entities such as international water agencies, federal and state agencies, industry, non-governmental agencies, and private organizations. The key (identified) water issues across these sectors were presented to workshop attendees and used during workshop debates and sessions. However, the key water issues of federally recognized Native American tribes remained less understood, resulting in a workshop proposal for additional research and LLNL potentially hosting a dialog with representatives of these tribes. Federally recognized Native American tribes have a unique government-to-government relationship with the United States (U.S.) government, in contrast to other sectors researched for the workshop. Within the U.S., the number of federally recognized tribes currently stands at 562 and, in addition to this large number of tribes, much diversity across these tribes exists. For the purposes of this preliminary research and report, it was necessary to confine the analysis to a smaller geographic area, yet still represent the diversity of tribes and context within which tribal water issues arise. The state of California provides this opportunity. California has 106 federally recognized tribes. California is diverse in its geography, environment, demographics, and economic bases; California tribes demonstrate similar diversity. Additionally, no central repository of national or state tribal water issues exists and information must be aggregated, in general, tribe by tribe. This presents research challenges and, for this report, these were overcome by developing a method to essentially ''sub-sample'' the 106 federally recognized tribes in the state, while making every effort to maintain a sub-sample that broadly represents all of the 106 tribes. n an effort to develop an equitable and appropriate method with which to identify this set of representative tribes, multiple entities were contacted for guidance. Consultation with the Bureau of Indian Affairs (BIA), Environmental Protection Agency (EPA), Indian Health Services (IHS), U.S. Department of Agriculture (USDA), Bureau of Reclamation (BOR) and Tribal Environmental Directors, provided key information and recommendations to guide the research process. It is hoped that an appropriate representation of the diversity of tribes across the state has been achieved; this includes an adequate representation of similarities and differences between Californian tribes on key water research issues (and the same between regions). This research occurred over a limited time period (i.e., three months) and given a general concern that this may not be sufficient, any information and conclusions in this report should be viewed with this in mind. Finally, it is hoped that this research allows for an (enhanced) informed capacity to better propose further dialog between tribes and LLNL to continue to exchange water research perspectives and define potential research collaborations.« less

Did I Tell You That? Ethical Issues Related to Using Computational Methods to Discover Non-Disclosed Patient Characteristics

PubMed Central

Cato, Kenrick D; Bockting, Walter; Larson, Elaine

2016-01-01

Background Widespread availability of large data sets through warehousing of electronic health records coupled with increasingly sophisticated information technology and related statistical methods offer great potential for a variety of applications for health and disease surveillance, developing predictive models and advancing decision support for clinicians. However, use of such ‘big data’ mining and discovery techniques has also raised ethical issues such as how to balance privacy and autonomy with the wider public benefits of data sharing. More specifically, electronic data are being increasingly used to identify individual characteristics which can be useful for clinical prediction and management, but that were not previously disclosed to a clinician. This process in computer parlance is called electronic phenotyping, and has a number of ethical implications. Approach Using the Belmont Report’s principles of respect for persons, beneficence, and justice as a framework, we examined the ethical issues posed by electronic phenotyping. Findings Ethical issues identified include the ability of the patient to consent for the use of their information, the ability to suppress pediatric information, ensuring that the potential benefits justify the risks of harm to patients, and acknowledging that the clinician’s biases or stereotypes, conscious or unintended, may also become a factor in the therapeutic interaction. We illustrate these issues with two vignettes, using the person characteristic of gender minority status (i.e., transgender identity) and the health history characteristic of substance abuse. Conclusion Big data mining has the potential to uncover patient characteristics previously obscured which can provide clinicians with beneficial clinical information. Hence, ethical guidelines must be updated to ensure that electronic phenotyping supports the principles of respect for persons, beneficence, and justice. PMID:27534587

Physiotherapy clinical educators' perceptions of student fitness to practise.

Lo, Kristin; Curtis, Heather; Keating, Jennifer L; Bearman, Margaret

2017-01-17

Health professional students are expected to maintain Fitness to Practise (FTP) including clinical competence, professional behaviour and freedom from impairment (physical/mental health). FTP potentially affects students, clinicians and clients, yet the impact of supervising students across the spectrum of FTP issues remains relatively under-reported. This study describes clinical educators' perceptions of supporting students with FTP issues. Between November 2012 and January 2013 an online survey was emailed to physiotherapy clinical educators from 34 sites across eight health services in Australia. The self-developed survey contained both closed and open ended questions. Demographic data and Likert scale responses were summarised using descriptive statistics. The hypotheses that years of clinical experience increased clinical educator confidence and comfort in supporting specific student FTP issues were explored with correlational analysis. Open text questions were analysed based on thematic analysis. Sixty-one percent of the 79 respondents reported supervising one or more students with FTP issues. Observed FTP concerns were clinical competence (76%), mental health (51%), professional behaviour (47%) and physical health (36%). Clinicians considered 52% (95% CI 38-66) of these issues avoidable through early disclosure, student and clinician education, maximising student competency prior to commencing placements, and human resources. Clinicians were confident and comfortable supporting clinical competence, professional behaviour and physical health issues but not mental health issues. Experience significantly increased confidence to support all FTP issues but not comfort. Student FTP issues affects the clinical educator role with 83% (95% CI 75-92) of clinicians reporting that work satisfaction was affected due to time pressures, emotional impact, lack of appreciation of educator time, quality of care conflict and a mismatch in role perception. Educators also considered that FTP issues affect service delivery and impact on those seeking health care. Strategies to support student FTP have potential to positively impact on students, clinicians and clients. Collaboration between these stakeholders is required, particularly in supporting mental health. Universities are strategically placed to implement appropriate support such as communication support.

Goldberg, Caren S.; Strickler, Katherine M.; Pilliod, David S.

2015-01-01

The discovery that macroorganisms can be detected from their environmental DNA (eDNA) in aquatic systems has immense potential for the conservation of biological diversity. This special issue contains 11 papers that review and advance the field of eDNA detection of vertebrates and other macroorganisms, including studies of eDNA production, transport, and degradation; sample collection and processing to maximize detection rates; and applications of eDNA for conservation using citizen scientists. This body of work is an important contribution to the ongoing efforts to take eDNA detection of macroorganisms from technical breakthrough to established, reliable method that can be used in survey, monitoring, and research applications worldwide. While the rapid advances in this field are remarkable, important challenges remain, including consensus on best practices for collection and analysis, understanding of eDNA diffusion and transport, and avoidance of inhibition in sample collection and processing. Nonetheless, as demonstrated in this special issue, eDNA techniques for research and monitoring are beginning to realize their potential for contributing to the conservation of biodiversity globally.

NASA's Earth Science Applications Directorate evaluated the potential of NASA remote sensing data and modeling products to enhance the General NOAA Oil Modeling Environment (GNOME) decision support tool. NOAA's Office of Response and Restoration (OR&R) Hazardous Materials (HAZMAT) Response Division is interested in enhancing GNOME with near-realtime (NRT) NASA remote sensing products on oceanic winds and ocean circulation. The NASA SeaWinds sea surface wind and Jason-1 sea surface height NRT products have potential, as do sea surface temperature and reflectance products from the Moderate Resolution Imaging Spectroradiometer and sea surface reflectance products from Landsat and the Advanced Spaceborne Thermal Emission and Reflectance Radiometer. HAZMAT is also interested in the Advanced Circulation model and the Ocean General Circulation Model. Certain issues must be considered, including lack of data continuity, marginal data redundancy, and data formatting problems. Spatial resolution is an issue for near-shore GNOME applications. Additional work will be needed to incorporate NASA inputs into GNOME, including verification and validation of data products, algorithms, models, and NRT data.

2011-09-01

This article addresses the current paradigms of surgical oncology training and the directions in which the training process may evolve over the course of the next decade. In doing so, the potential influences upon this evolution are discussed along with potential barriers associated with each of these factors. In particular, the topics include issues of specialty training with regard to new technologies and procedures, involvement of the surgeon as part of the multi-disciplinary team of oncologists, and the very real issue of burnout and career satisfaction associated with the profession of surgical oncology. Changes to the training of tomorrow's cancer surgeons will need to involve each one of these factors in a comprehensive and efficient manner, in order to ensure the continued strength and growth of the field.

1993-01-01

Basic research will spur development of genetic tests that are capable of presymptomatic prediction of disease, disability, and premature death in presently asymptomatic individuals. Concerns have been expressed about potential harms related to the use of genetic test results, especially loss of confidentiality, eugenics, and discrimination. Existing laws and administrative policies may not be sufficient to assure that genetic information is used fairly. To provide factual information and conceptual principles upon which sound social policy can be based, the Human Genome Initiative established an Ethical, Legal, and Social Issues Program. Among the first areas to be identified as a priority for study was insurance. This paper provides a review of life, health, and disability insurance systems, including basic principles, risk classification, and market and regulatory issues, and examines the potential impact of genetic information on the insurance industry.

The Electric Insertion Transfer Experiment (ELITE) - An Air Force critical experiment to revolutionize space transportation

NASA Astrophysics Data System (ADS)

Matlock, Richard S.; Feig, Jason R.; Dickey, Michael R.

A program called the Electric Insertion Transfer Experiment or ELITE for demonstrating the use of solar-electric propulsion is proposed and described. The ELITE concept is based on the use of solar propulsion for the orbit-raising mode of an electric orbital-transfer vehicle (EOTV) and examines issues associated with electric thrusters. Experimental subsystems are compared including arcjet, ion, and magnetoplasmadynamic thrusters, and the design and performance impacts on EOTVs are listed. The ELITE experiment is shown to be capable of studying such issues as the plume-to-plume interaction of multiple thrusters, the contamination of spacecraft components, potential interferences from radio-frequency transmissions, and the charging of spacecraft surfaces. Solar propulsion can be studied within the context of the ELITE program to demonstrate its potential as both enhancing and enabling technology.

Solar Energy Economics Revisited: The Promise and Challenge of Orbiting Reflectors for World Energy Supply

NASA Technical Reports Server (NTRS)

Billman, Kenneth W.; Gilbreath, William P.; Bowen, Stuart W.

1978-01-01

A system of orbiting, large-area, low mass density reflector satellites which provide nearly continuous solar energy to a world-distributed set of conversion sites is examined under the criteria for any potential new energy system: technical feasibility, significant and renewable energy impact, economic feasibility and social/political acceptability. Although many technical issues need further study, reasonable advances in space technology appear sufficient to implement the system. The enhanced insolation is shown to greatly improve the economic competitiveness of solar-electric generation to circa 1995 fossil/nuclear alternatives. The system is shown to have the potential for supplying a significant fraction of future domestic and world energy needs. Finally, the environmental and social issues, including a means for financing such a large shift to a world solar energy dependence, is addressed.

The telephone has become an indispensable method of communication in the practice of obstetrics. The telephone is one of the primary methods by which the patient makes her appointments and contacts her health care provider for advice, reassurance, and referrals. Current methods of telephone triage include personal at the physicians' office, telephone answering services, labor and delivery nurses, and a dedicated telephone triage system using algorithms. Limitations of telephone triage include the inability of the provider to see the patient and receive visual clues from the interaction and the challenges of obtaining a complete history over the telephone. In addition, there are potential safety and legal issues with telephone triage. To date, there is insufficient evidence to either validate or refute the use of a dedicated telephone triage system compared with a traditional system using an answering service or nurses on labor and delivery. Obstetricians and gynecologists, family physicians. After completing this CME activity, physicians should be better able to analyze the scope of variation in telephone triage across health care providers and categorize the components that go into a successful triage system, assess the current scope of research in telephone triage in obstetrics, evaluate potential safety and legal issues with telephone triage in obstetrics, and identify issues that should be addressed in any institution that is using or implementing a system of telephone triage in obstetrics.

Little research has explored the possible effects of government institutions in emerging economies on ethical reviews of multinational research. We conducted semi-structured, in-depth telephone interviews with 15 researchers, Research Ethics Committees (RECs) personnel, and a government agency member involved in multinational HIV Prevention Trials Network (HPTN) research in emerging economies. Ministries of Health (MOH) or other government agencies often play pivotal roles as facilitators or barriers in the research ethics approval process. Government agency RECs reviewing protocols may face particular challenges, as they can lack resources, be poorly organized, have inconsistent review processes and, limited expertise, use differing definitions of national interests, including upholding national reputation and avoiding potential exploitation and stigma of the country’s population. The MOH/governmental review body may be affected by power dynamics and politics in study reviews; may consider issues both related and unrelated to research ethics as understood elsewhere; and may prioritize particular diseases, treatments, or interventions over other topics/types of research. Poor communication and deeply-rooted tensions may exist between sponsor and host countries, impeding optimal interactions and reviews. Investigators must understand and plan for the potential effects of governmental agencies on multinational collaborative research, including preserving adequate time for agency review, and contacting these agencies beforehand to address issues that may arise. Better understanding of these issues can aid and advance appropriate global scientific collaboration. PMID:25388003

2016-09-01

The objectives in this article are the exploration of demographic and service usage data gained through clinical data mining audit and suggesting recommendations for social work service delivery model and future research. The method is clinical data-mining audit of 100 sequentially sampled cases gathering quantitative demographic and service usage data. Descriptive analysis of file audit data raised interesting trends with potential to inform service delivery and usage; the key areas of the results included patient demographics, family involvement and impact, and child safety and risk issues. Transport accidents involving children often include other family members. Care planning must take into account psychosocial issues including patient and family emotional responses, availability of primary carers, and other practical needs that may impact on recovery and discharge planning. This study provides evidence to plan for further research and development of more integrated models of care.

AIDS and the responsibilities of academic health science centers: a case law approach.

PubMed

McKenzie, S B

1992-01-01

The advent of AIDS and HIV infection has heightened administrator and faculty concern over providing and maintaining a safe environment for students in the health professions. Failure to provide this environment may result in litigation. Although case law on AIDS-related issues in higher education is sparse, court decisions on related issues are helpful in providing guidance on university responsibility. Case law indicates that if faculty provide appropriate supervision and give adequate instruction, including accepted safety practices, the courts will determine that the university has provided reasonable care to prevent student exposure to HIV. Other issues, related to HIV-positive students, demand that universities create carefully deliberated policies and procedures that do not discriminate against these individuals. This paper is the result of research on case law as it pertains to the potential legal issues of HIV and the university.

Prescription Drug Monitoring Programs: Ethical Issues in the Emergency Department.

2016-11-01

Prescription drug monitoring programs are statewide databases available to clinicians to track prescriptions of controlled medications. These programs may provide valuable information to assess the history and use of controlled substances and contribute to clinical decisionmaking in the emergency department (ED). The widespread availability of the programs raises important ethical issues about beneficence, nonmaleficence, respect for persons, justice, confidentiality, veracity, and physician autonomy. In this article, we review the ethical issues surrounding prescription drug monitoring programs and how those issues might be addressed to ensure the proper application of this tool in the ED. Clinical decisionmaking in regard to the appropriate use of opioids and other controlled substances is complex and should take into account all relevant clinical factors, including age, sex, clinical condition, medical history, medication history and potential drug-drug interactions, history of addiction or diversion, and disease state.

Pediatric Issues in Return of Results and Incidental Findings: Weighing Autonomy and Best Interests.

PubMed

Holm, Ingrid A

2017-03-01

Nowhere are the ethical issues in genomic research more complex than in pediatrics. Balancing the sometime conflicting autonomy of the parent and the child, and the best interest of the family and the child, brings up many challenging issues. Addressing this balance, especially in the context of the child's developing maturity and comprehension, requires deep analysis and discussion. Issues discussed include the impact of genetic information on the family, parental versus the child's autonomy, the best interests of the child versus the family, potential limitations on the parents' right to know or not know information about their child, and changing role of the developing child in return of research results. Finally, a dynamic model will be proposed that takes into consideration the child's evolving role in consenting and return of results that can be adapted in different national contexts.

Emerging issues in biodiversity & conservation management: The need for a palaeoecological perspective

Froyd, C. A.; Willis, K. J.

2008-09-01

The study of Quaternary environmental change is directly applicable to on-going issues of global conservation. Palaeoecological research techniques provide the tools to address some of the key questions presently being asked by conservation ecologists and land management organizations. But is this type of analysis currently being utilized to its full potential? Are the results of palaeoenvironmental analyses routinely applied to practical issues of natural resource management, and if not what can be done to expand the application of this research within the conservation community? This paper reviews recent developments in the application of the analysis of late Quaternary environmental change to key environmental issues of biodiversity and conservation management and examines areas which could be strengthened in the future including: (i) determination of baselines and natural ecosystem variability; (ii) understanding ecological thresholds and resilience; (iii) climate change conservation strategies; (iv) biological invasions; and (v) conservation and culture.

Beyond research: a primer for considerations on using viral metagenomics in the field and clinic.

2015-01-01

Powered by recent advances in next-generation sequencing technologies, metagenomics has already unveiled vast microbial biodiversity in a range of environments, and is increasingly being applied in clinics for difficult-to-diagnose cases. It can be tempting to suggest that metagenomics could be used as a "universal test" for all pathogens without the need to conduct lengthy serial testing using specific assays. While this is an exciting prospect, there are issues that need to be addressed before metagenomic methods can be applied with rigor as a diagnostic tool, including the potential for incidental findings, unforeseen consequences for trade and regulatory authorities, privacy and cultural issues, data sharing, and appropriate reporting of results to end-users. These issues will require consideration and discussion across a range of disciplines, with inclusion of scientists, ethicists, clinicians, diagnosticians, health practitioners, and ultimately the public. Here, we provide a primer for consideration on some of these issues.

Quality assurance exercises and networking on the detection of highly infectious pathogens (QUANDHIP) is a joint action initiative set up in 2011 that has successfully unified the primary objectives of the European Network on Highly Pathogenic Bacteria (ENHPB) and of P4-laboratories (ENP4-Lab) both of which aimed to improve the efficiency, effectiveness, and response capabilities of laboratories directed at protecting the health of European citizens against high consequence bacteria and viruses of significant public health concern. Both networks have established a common collaborative consortium of 37 nationally and internationally recognized institutions with laboratory facilities from 22 European countries. The specific objectives and achievements include the initiation and establishment of a recognized and acceptable quality assurance scheme, including practical external quality assurance exercises, comprising living agents, that aims to improve laboratory performance, accuracy, and detection capabilities in support of patient management and public health responses; recognized training schemes for diagnostics and handling of highly pathogenic agents; international repositories comprising highly pathogenic bacteria and viruses for the development of standardized reference material; a standardized and transparent Biosafety and Biosecurity strategy protecting healthcare personnel and the community in dealing with high consequence pathogens; the design and organization of response capabilities dealing with cross-border events with highly infectious pathogens including the consideration of diagnostic capabilities of individual European laboratories. The project tackled several sensitive issues regarding Biosafety, Biosecurity and "dual use" concerns. The article will give an overview of the project outcomes and discuss the assessment of potential "dual use" issues.

Speech and language pathology & pediatric HIV.

PubMed

Retzlaff, C

1999-12-01

Children with HIV have critical speech and language issues because the virus manifests itself primarily in the developing central nervous system, sometimes causing speech, motor control, and language disabilities. Language impediments that develop during the second year of life seem to be especially severe. HIV-infected children are also susceptible to recurrent ear infections, which can damage hearing. Developmental issues must be addressed for these children to reach their full potential. A decline in language skills may coincide with or precede other losses in cognitive ability. A speech pathologist can play an important role on a pediatric HIV team. References are included.

Arsenic (As) distribution and toxicology in the environment is a serious issue, with millions of individuals worldwide being affected by As toxicosis. Sources of As contamination are both natural and anthropogenic and the scale of contamination ranges from local to regional. There are many areas of research that are being actively pursued to address the As contamination problem. These include new methods of screening for As in the field, determining the epidemiology of As in humans, and identifying the risk of As uptake in agriculture. Remediation of As-affected water supplies is important and research includes assessing natural remediation potential as well as phytoremediation. Another area of active research is on the microbially mediated biogeochemical interactions of As in the environment.In 2005, a conference was convened to bring together scientists involved in many of the different areas of As research. In this paper, we present a synthesis of the As issues in the light of long-standing research and with regards to the new findings presented at this conference. This contribution provides a backdrop to the issues raised at the conference together with an overview of contemporary and historical issues of As contamination and health impacts.

The new human papillomavirus (HPV) vaccine: pros and cons for pediatric and adolescent health.

2008-01-01

The new human papillomavirus (HPV) vaccine is a research breakthrough for pediatric/adolescent health to prevent cervical cancer and related morbidity. The annual heath care cost for the treatment of cervical cancer and genital warts is estimated to be more than three billion dollars a year. The new HPV vaccine has incredible potential to improve reproductive health promotion, reduce health care costs, and close health care disparity gaps. However, issues both for and against the new HPV vaccine, including mandating vaccination, high cost of the vaccine, the short duration of protection offered, and the perceived promotion of sexual activity, cause confusion. Pediatric nurses, including those in advanced practice, benefit by understanding the pros and cons of these issues in advocating for their patients.

The Influence of Weight-of-Evidence Messages on (Vaccine) Attitudes: A Sequential Mediation Model.

PubMed

Clarke, Christopher E; Weberling McKeever, Brooke; Holton, Avery; Dixon, Graham N

2015-01-01

Media coverage of contentious risk issues often features competing claims about whether a risk exists and what scientific evidence shows, and journalists often cover these issues by presenting both sides. However, for topics defined by scientific agreement, balanced coverage erroneously heightens uncertainty about scientific information and the issue itself. In this article, we extend research on combating so-called information and issue uncertainty using weight of evidence, drawing on the discredited autism-vaccine link as a case study. We examine whether people's perceptions of issue uncertainty (about whether a link exists) change before and after they encounter a news message with weight-of-evidence information. We also explore whether message exposure is associated with broader issue judgments, specifically vaccine attitudes. Participants (n = 181) read news articles that included or omitted weight-of-evidence content stating that scientific studies have found no link and that scientists agree that none exists. Postexposure issue uncertainty decreased-in other words, issue certainty increased-from preexposure levels across all conditions. Moreover, weight-of-evidence messages were associated with positive vaccine attitudes indirectly via reduced information uncertainty (i.e., one's belief that scientific opinion and evidence concerning a potential link is unclear) as well as issue uncertainty. We discuss implications for risk communication.

Ethical Issues in Measuring Biomarkers in Children’s Environmental Health

2009-01-01

Background Studying the impact of environmental exposures is important in children because they are more vulnerable to adverse effects on growth, development, and health. Assessing exposure in children is difficult, and measuring biomarkers is potentially useful. Research measuring biomarkers in children raises a number of ethical issues, some of which relate to children as research subjects and some of which are specific to biomarker research. Objective As an international group with experience in pediatric research, biomarkers, and the ethics of research in children, we highlight the ethical issues of undertaking biomarker research in children in these environments. Discussion Significant issues include undertaking research in vulnerable communities, especially in developing countries; managing community expectations; obtaining appropriate consent to conduct the research; the potential conflicts of obtaining permission from an ethics review board in an economically developed country to perform research in a community that may have different cultural values; returning research results to participants and communities when the researchers are uncertain of how to interpret the results; and the conflicting ethical obligations of maintaining participant confidentiality when information about harm or illegal activities mandate reporting to authorities. Conclusion None of these challenges are insurmountable and all deserve discussion. Pediatric biomarker research is necessary for advancing child health. PMID:19672395

Central venous catheters: legal issues.

2011-01-01

In dialysis patients, both central venous catheter (CVC) insertion and CVC use during the dialysis procedure pose important legal issues, because of potentially severe, even fatal, complications. The first issue is the decision of the kind of vascular access that should be proposed to patients: an arteriovenous (AV) fistula, a graft, or a CVC. The second issue, when choosing the CVC option, is the choice of CVC: nontunneled versus tunneled. Leaving a temporary nontunneled CVC for a prolonged time increases the risk of complications and could raise a liability issue. Even when choosing a long-term tunneled CVC, nephrologists should systematically explain its potential harms, presenting them as "unsafe for long-term use" unless there is a clear contraindication to an AV native or prosthetic access. Another critical issue is the preparation of a complete, informative, and easy-to-understand consent form. The CVC insertion procedure has many aspects of legal interest, including the choice of CVC, the use of ECG monitoring, the use of ultrasound guidance for cannulation, and the use of fluoroscopy for checking the position of the metal guidewire during the procedure as well as the CVC tip before the end of the procedure. Use of insertion devices and techniques that can prevent complications should obviously be encouraged. Complications of CVC use are mainly thrombosis and infection. These are theoretically expected as pure complications (and not as malpractice effects), but legal issues might relate to inappropriate catheter care (in both the inpatient and outpatient settings) rather than to the event per se. Thus, in the individual case it is indeed very difficult to establish malpractice and liability with a catheter-related infection or thrombosis. In conclusion, we cannot avoid complications completely when using CVCs, but reducing them to a minimum and adopting safe approaches to their insertion and use will reduce legal liability.

2008-01-01

Objectives To analyze the implementation of Medicaid preferred drug lists (PDLs) in a number of states and determine its impact on quality of care and cost relative to other segments of healthcare. Methods We reviewed research and case studies found by searching library databases, primarily MEDLINE and EBSCOHost, and searching pertinent journals. Keywords initially included “drug lists,” “prior authorization,” “prior approval,” and “Medicaid.” We added terms such as “influence use of other healthcare services,” “quality of care,” and “overall economic impact.” We mainly used primary sources. Results Based on our literature review, we determined that there are a number of issues regarding Medicaid PDLs that need to be addressed. Some issues include: (a) the potential for PDLs to influence the utilization of other healthcare services, (b) criteria used by Medicaid for determining acceptance of drugs onto a PDL, (c)the effect of PDL implementation on compliance to new regimens, (d) the potential effects of restricting medication availability on quality of care, (e) administrative costs associated with PDLs, and (f) satisfaction rates among patients and medical providers. This review highlighted expected short-term cost savings with limited degree of compromised quality of PDL implementation, but raised the concern about the potential long-term decline in quality of care and overall economic impact. Conclusions The number of concerns raised indicates that further studies are warranted regarding both short-term cost benefits as well as potential long-term effects of Medicaid PDL implementation. Objective analysis of these effects is necessary to ensure cost-effectiveness and quality of care. PMID:18561515

A Primer for Preventing Teen Dating Violence? The Representation of Teen Dating Violence in Young Adult Literature and Its Implications for Prevention.

PubMed

Storer, Heather L; Strohl, Katyayani R

2016-09-18

Teen dating violence (TDV) is a significant public health issue. Preventing TDV requires attention to risk and protective factors across ecological system levels. The media is one of the primary cultural drivers of societal-level social scripts about the causes of TDV. Framing theory asserts that the media's portrayal of social issues, including what contextual information is included and/or excluded, affects individual-level attitudes about TDV and potential policy responses. This study investigates the representation of TDV in young adult (YA) literature, a media genre that is marketed to adolescent audiences. Data include all YA novels (N = 8) that have a primary focus on TDV. Texts were analyzed systematically using thematic content analysis methods. Results indicate that the antecedents of TDV were portrayed as being related to victim personal characteristics such as inexperience in relationships and low self-esteem. Rather than underscoring how societal-level factors contribute to TDV, perpetration was seen as stemming from family dysfunction and mental health issues. These results underscore how the structural determinants of TDV have been overshadowed in the media's portrayal of TDV, in favor of narrow portrayals of victimization and perpetration. Implications for TDV prevention programs including the importance of media literacy are discussed. © The Author(s) 2016.

Boeing's program for Advanced Technology Composite Aircraft Structure (ATCAS) has focused on the manufacturing and performance issues associated with a wide body commercial transport fuselage. The primary goal of ATCAS is to demonstrate cost and weight savings over a 1995 aluminum benchmark. A 31 foot section of fuselage directly behind the wing to body intersection was selected for study purposes. This paper summarizes ATCAS contract plans and review progress to date. The six year ATCAS program will study technical issues for crown, side, and keel areas of the fuselage. All structural details in these areas will be included in design studies that incorporate a design build team (DBT) approach. Manufacturing technologies will be developed for concepts deemed by the DBT to have the greatest potential for cost and weight savings. Assembly issues for large, stiff, quadrant panels will receive special attention. Supporting technologies and mechanical tests will concentrate on the major issues identified for fuselage. These include damage tolerance, pressure containment, splices, load redistribution, post-buckled structure, and durability/life. Progress to date includes DBT selection of baseline fuselage concepts; cost and weight comparisons for crown panel designs; initial panel fabrication for manufacturing and structural mechanics research; and toughened material studies related to keel panels. Initial ATCAS studies have shown that NASA's Advanced Composite Technology program goals for cost and weight savings are attainable for composite fuselage.

Placental masses are uncommonly identified at the time of obstetric ultrasound evaluation. Understanding the pathologies presenting as placental masses is key for providing a differential diagnosis and guiding subsequent management, which may include additional imaging with magnetic resonance (MR) imaging. Potential benign entities include chorioangiomas and teratomas. Larger chorioangiomas can cause fetal cardiovascular issues from volume overload. Placental mesenchymal dysplasia has an association with fetal anomalies and detailed fetal evaluation should be performed when it is suspected. Identifying other cystic masses such as partial and complete moles is crucial to prevent erroneous pregnancy termination. This review addresses normal imaging appearance of the placenta on ultrasound and MR imaging and describes various trophoblastic and nontrophoblastic placental masses. Potential placental mass mimics including uterine contractions and thrombo-hematomas are also presented.

With regard to career issues, clarification of expectations and discussion between partners regarding career commitment, job selection and mobility, and maintenance of professional identity is emphasized. Benefits of dual-career relationships include shared occupational interests, financial rewards, and respect for each partner's professional expertise. Strategies for managing domestic responsibilities include modifying standards, setting priorities, and distributing tasks evenly among family members. Pharmacist couples who are parents have chosen several routes in managing child-care issues, including postponing childbearing until each adult's career is established, decreasing one partner's career involvement, and hiring community or in-home caretakers. Sharing equally in child care can help prevent an excessive workload for one parent. Progressive family-oriented employment practices may also aid dual-career couples with children. Striking a balance between career and family is identified as perhaps the most challenging task facing the dual-career couple; time distribution must be adjusted according to the couple's priorities. Identifying realistic priorities, negotiating honestly regarding attainment of mutual and individual goals, and maintaining flexibility are key in achieving success in the professional and private lives of two-pharmacist couples.

Science and Strategic - Climate Implications

NASA Astrophysics Data System (ADS)

Tindall, J. A.; Moran, E. H.

Energy of weather systems greatly exceeds energy produced and used by humans. Variation in this energy causes climate variability potentially resulting in local, national, and/or global catastrophes beyond our ability to deter the loss of life and economic destabilization. Large scale natural disasters routinely result in shortages of water, disruption of energy supplies, and destruction of infrastructure. The resulting unforeseen and disastrous events occurring beyond national emergency preparation, as related to climate variability, could insight civil unrest due to dwindling and/or inaccessible resources necessary for survival. Lack of these necessary resources in impacted countries often leads to wars. Climate change coupled with population growth, which exposes more of the population to potential risks associated with climate and environmental change, demands faster technological response. Understanding climate/associated environmental changes, the relation to human activity and behavior, and including this in national and international emergency/security management plans would alleviate shortcomings in our present and future technological status. The scale of environmental change will determine the potential magnitude of civil unrest at the local, national, and/or global level along with security issues at each level. Commonly, security issues related to possible civil unrest owing to temporal environmental change is not part of a short and/or long-term strategy, yet recent large-scale disasters are reminders that system failures (as in hurricane Katrina) include acknowledged breaches to individual, community, and infrastructure security. Without advance planning and management concerning environmental change, oncoming and climate related events will intensify the level of devastation and human catastrophe. Depending upon the magnitude and period of catastrophic events and/or environmental changes, destabilization of agricultural systems, energy supplies, and other lines of commodities often results in severely unbalanced supply and demand ratios, which eventually affect the entire global community. National economies potentially risk destabilization, which is especially important since economics plays a major role in strategic planning. This presentation will address these issues and the role that science can play in human sustainability and local, national, and international security.

The ethics of creating genetically modified children using genome editing.

PubMed

Ishii, Tetsuya

2017-12-01

To review the recent ethical, legal, and social issues surrounding human reproduction involving germline genome editing. Genome editing techniques, such as CRISPR/Cas9, have facilitated genetic modification in human embryos. The most likely purpose of germline genome editing is the prevention of serious genetic disease in offspring. However, complex issues still remain, including irremediable risks to fetuses and future generations, the role of women, the availability of alternatives, long-term follow-up, health insurance coverage, misuse for human enhancement, and the potential effects on adoption. Further discussions, a broad consensus, and appropriate regulations are required before human germline genome editing is introduced into the global society. Before germline genome editing is used for disease prevention, a broad consensus must be formed by carefully discussing its ethical, legal, and social issues.

Established in 1999, the Global Advisory Committee on Vaccine Safety advises the World Health Organization (WHO) on vaccine-related safety issues and enables WHO to respond promptly, efficiently, and with scientific rigor to issues of vaccine safety with potential global importance. The committee also assesses the implications of vaccine safety for practice worldwide and for WHO policies. We describe the principles on which the committee was established, its modus operandi, and the scope of the work undertaken, both present and future. We highlight its recent recommendations on major issues, including the purported link between the measles–mumps–rubella vaccine and autism and the safety of the mumps, influenza, yellow fever, BCG, and smallpox vaccines as well as that of thiomersal-containing vaccines.

Niemiec, Emilia; Kalokairinou, Louiza; Howard, Heidi Carmen

2017-09-01

A variety of health-related genetic testing is currently advertized directly to consumers. This article provides a timely overview of direct-to-consumer genetic testing (DTC GT) and salient ethical issues, as well as an analysis of the impact of the recently adopted regulation on in vitro diagnostic medical devices on DTC GT. DTC GT companies currently employ new testing approaches, report on a wide spectrum of conditions and target new groups of consumers. Such activities raise ethical issues including the questionable analytic and clinical validity of tests, the adequacy of informed consent, potentially misleading advertizing, testing in children, research uses and commercialization of genomic data. The recently adopted regulation on in vitro diagnostic medical devices may limit the offers of predisposition DTC GT in the EU market.

Ethical issues when using social media for health outside professional relationships.

PubMed

DeCamp, Matthew

2015-04-01

Social media have the potential to revolutionize health and healthcare, but fulfilling this potential requires attention to the ethical issues social media may raise. This article reviews the major ethical issues arising when social media are used for research, public health, mobile health applications, and global health. It focuses on social media use outside fiduciary relationships between healthcare professionals and patients. Emphasis is given to the potential of social media in these contexts, the ethical issues relatively unique to each, and where possible how existing ethical principles and frameworks could help navigate these issues. In some cases social media create the circumstance for particular ethical issues but also facilitate managing them, such as in informed consent for research. In other cases, disagreement exists about whether social media - despite their potential - should be used for certain purposes, such as in public health surveillance (where confidentiality represents a significant ethical concern). In still others, ethical uncertainty exists about how social media will affect ethical issues, such as inequality in global health. As social media technologies continue to develop, identifying and managing the ethical issues they raise will be critical to their success in improving health while preserving fundamental ethical values.

Conceptual and Analytical Considerations toward the Use of Patient-Reported Outcomes in Personalized Medicine.

PubMed

Alemayehu, Demissie; Cappelleri, Joseph C

2012-07-01

Patient-reported outcomes (PROs) can play an important role in personalized medicine. PROs can be viewed as an important fundamental tool to measure the extent of disease and the effect of treatment at the individual level, because they reflect the self-reported health state of the patient directly. However, their effective integration in personalized medicine requires addressing certain conceptual and methodological challenges, including instrument development and analytical issues. To evaluate methodological issues, such as multiple comparisons, missing data, and modeling approaches, associated with the analysis of data related to PRO and personalized medicine to further our understanding on the role of PRO data in personalized medicine. There is a growing recognition of the role of PROs in medical research, but their potential use in customizing healthcare is not widely appreciated. Emerging insights into the genetic basis of PROs could potentially lead to new pathways that may improve patient care. Knowledge of the biologic pathways through which the various genetic predispositions propel people toward negative or away from positive health experiences may ultimately transform healthcare. Understanding and addressing the conceptual and methodological issues in PROs and personalized medicine are expected to enhance the emerging area of personalized medicine and to improve patient care. This article addresses relevant concerns that need to be considered for effective integration of PROs in personalized medicine, with particular reference to conceptual and analytical issues that routinely arise with personalized medicine and PRO data. Some of these issues, including multiplicity problems, handling of missing values-and modeling approaches, are common to both areas. It is hoped that this article will help to stimulate further research to advance our understanding of the role of PRO data in personalized medicine. A robust conceptual framework to incorporate PROs into personalized medicine can provide fertile opportunity to bring these two areas even closer and to enhance the way a specific treatment is attuned and delivered to address patient care and patient needs.

Mitigating Adverse Effects of a Human Mission on Possible Martian Indigenous Ecosystems

2000-01-01

Although human beings are, by most standards, the most capable agents to search for and detect extraterrestrial life, we are also potentially the most harmful. While there has been substantial work regarding forward contamination with respect to robotic missions, the issue of potential adverse effects on possible indigenous Martian ecosystems, such as biological contamination, due to a human mission has remained relatively unexplored and may require our attention now as this presentation will try to demonstrate by exploring some of the relevant scientific questions, mission planning challenges, and policy issues. An informal, high-level mission planning decision tree will be discussed and is included as the next page of this abstract. Some of the questions to be considered are: (1) To what extent could contamination due to a human presence compromise possible indigenous life forms? (2) To what extent can we control contamination? For example, will it be local or global? (3) What are the criteria for assessing the biological status of Mars, both regionally and globally? For example, can we adequately extrapolate from a few strategic missions such as sample return missions? (4) What should our policies be regarding our mission planning and possible interaction with what are likely to be microbial forms of extraterrestrial life? (5) Central to the science and mission planning issues is the role and applicability of terrestrial analogs, such as Lake Vostok for assessing drilling issues, and modeling techniques. Central to many of the policy aspects are scientific value, international law, public concern, and ethics. Exploring this overall issue responsibly requires an examination of all these aspects and how they interrelate. A chart is included, titled 'Mission Planning Decision Tree for Mitigating Adverse Effects to Possible Indigenous Martian Ecosystems due to a Human Mission'. It outlines what questions scientists should ask and answer before sending humans to Mars.

2018-05-31

As telemedicine and telehealth services are experiencing increasing rates of adoption, industry leaders and healthcare service providers are becoming increasingly focused on human resource issues encountered in the delivery of a broad range of telehealth services. To create a forum for the discussion of many interrelated elements of telehealth service industry, a national conference entitled "Telemedicine & Telehealth Service Provider Showcase" (SPS) Conference was established in 2014, and repeated in 2016 and 2017, in Arizona. These SPS Conferences include thought leaders, telehealth service providers, government administrators, and academicians from leading programs addressing service provider workforce issues. This report summarizes the content of SPS 2017 conference, held in Phoenix, AZ, October 2-3, 2017. The topics covered at SPS 2017 include using telehealth services as a strategic asset; development of appropriate effective partnerships; direct-to-consumer initiatives; important reimbursement, legislative, and regulatory issues (i.e., Centers for Medicare & Medicaid Services [CMS] approaches, financial models, and return on investment [ROI]); marketing; evaluation and applied metrics; remote monitoring and sensors; integration with electronic health records; and overall lessons learned. The content of SPS 2017 is summarized in the body of this report. The SPS 2017 program evaluators included attendees, speakers, and exhibitors. The knowledge attendees gained at SPS 2017 was characterized, by all three groups, as forward-looking and practical. SPS 2017 succeeded in identifying, and focusing on, solutions for issues, challenges, and barriers impacting the rapidly expanding telehealth service segment of the healthcare industry. The growing interest in this annual SPS Conference series apparently reflects, in part, the program committee's successes in identifying practical issues and their potential solutions.

Ethical, Legal, Social, and Policy Implications of Behavioral Genetics

PubMed Central

Berryessa, Colleen M.; Cho, Mildred K.

2015-01-01

The field of behavioral genetics has engendered a host of moral and social concerns virtually since its inception. The policy implications of a genetic basis for behaviors are widespread and extend beyond the clinic to the socially important realms of education, criminal justice, childbearing, and child rearing. The development of new techniques and analytic approaches, including whole-genome sequencing, noninvasive prenatal genetic testing, and optogenetics, has clearly changed the study of behavioral genetics. However, the social context of biomedical research has also changed profoundly over the past few decades, and in ways that are especially relevant to behavioral genetics. The ever-widening scope of behavioral genetics raises ethical, legal, social, and policy issues in the potential new applications to criminal justice, education, the military, and reproduction. These issues are especially critical to address because of their potentially disproportionate effects on vulnerable populations such as children, the unborn, and the incarcerated. PMID:23452225

During September 2009 to September 2010, we conducted 10 focus groups and 36 in-depth interviews (n = 140) in Lima and Iquitos, Peru, and Guayaquil, Ecuador, to examine 5 RM domains: knowledge, thoughts and opinions about RM as an HIV prevention tool, use, condoms, and social concerns. We coded emergent themes in recorded and transcribed data sets and extracted representative quotes. We collected sociodemographic information with a self-administered questionnaire. RM issues identified included limited knowledge; concerns regarding plausibility, side effects, and efficacy; impact on condom use; target users (insertive vs receptive partners); and access concerns. Understanding the sociocultural issues affecting RMs is critical to their uptake and should be addressed prior to product launch.

Attention Deficit Hyperactivity Disorder on YouTube: Framing, Anchoring, and Objectification in Social Media.

PubMed

Kang, Seok; Ha, Jae-Sik; Velasco, Teresa

2017-05-01

This study investigated videos about Attention Deficit Hyperactivity Disorder (ADHD) on YouTube in terms of issues, sources, and episodic-thematic aspects. A total of 685 videos uploaded onto YouTube between 2006 and 2014 were content analyzed. Results demonstrated that the top three key issues about ADHD were symptom, child, and treatment. Doctor, patient, and supporter were the three most interviewed sources. Videos from the public sector including the government, company representative, and public organizations were relatively rare compared to other sources suggesting the potential for a greater role for the government and public sector contributions to YouTube to provide credible information relevant to public awareness, campaigns, and policy announcements. Meanwhile, many personal videos in the episodic frame advocated social solutions. This result implies that YouTube videos about health information from the private sectors have the potential to affect change at the social level.

GRACE Follow-On and Potential Successors: Mission Options for the Upcoming Decadaes

NASA Astrophysics Data System (ADS)

Watkins, M. M.

2017-12-01

The GRACE Follow-On mission is currently scheduled to launch in the first quarter of 2018, providing a successor to GRACE for ongoing critical measurements of Earth's time varying mass distribution for the coming decade. As noted in the literature (and in several talks in this session), there are also several possible mission proposals and technologies to either augment or succeed GRACE FO for extended and improved measurements. Various scientific, programmatic, and technical issues drive each of these potential missions and these factors will be important in determining which will ultimately be selected for flight. These issues include accuracy requirements based on science goals, technical maturity, cost, and international partnership options. In this talk, we will provide a final detailed update before launch on the GRACE Follow-On status and expectations, and we will outline several of the key options for future missions after GRACE FO.

Regulating the helping hand: improving legal preparedness for cross-border disaster medicine.

PubMed

Fisher, David

2010-01-01

Medical care is a highly regulated field in nearly every country. Therefore, it is not surprising that legal issues regularly arise in cross-border disaster operations that have with the potential to profoundly impact the effectiveness of international assistance. Little attention has been paid to preparing for and addressing these kinds of issues. This paper will report on research by the International Federation of Red Cross and Red Crescent Societies (IFRC) on International Disaster Response Law, and discuss new developments in the international legal framework for addressing these issues. For seven years, the IFRC has studied legal issues in cross-border disaster assistance. Its activities have included several dozen case studies, a global survey of governments and humanitarian stakeholders, and a series of meetings and high-level conferences. The IFRC has found a consistent set of regulatory problems in major disaster relief operations related to the entry and regulation of international relief. These include some issues specific to the health field, such as the regulation of drug donations and the recognition of foreign medical qualifications. To address the gaps in domestic and international regulatory structures, the IFRC spearheaded the development of new international guidelines. The legal risks for international health providers in disaster settings are real and should be better integrated into program planning. Governments must become more proactive in ensuring that legal frameworks are flexible enough to mitigate these problems.

Data were sourced by a literature search using MEDLINE, Embase, PsycINFO and a manual search of scientific journals to identify relevant articles. Clinical practice guidelines from the American Psychiatric Association, National Institute of Clinical Excellence, Royal Australian and New Zealand College of Psychiatrists and World Federation of Societies of Biological Psychiatry were sourced. Prescription data were sourced from Australian governmental sources. Alprazolam has shown efficacy for control of PD symptoms, particularly in short-term controlled clinical trials, but is no longer recommended as a first-line pharmacological treatment due to concerns about the risks of developing tolerance, dependence and abuse potential. Almost no evidence is available comparing alprazolam to current first-line pharmacological treatment. Despite this, prescription rates are increasing. A number of potential issues including use in overdose and impact on car accidents are noted. conclusion: Although effective for PD symptoms in clinical trials, a number of potential issues may exist with use. Consideration of its future place in PD treatment in Australia may be warranted.

Preservation of Fertility Potential for Gender and Sex Diverse Individuals.

Johnson, Emilie K; Finlayson, Courtney

2016-01-01

Gender and sex diverse individuals-transgender individuals and those with disorders of sex development (DSD)-both face medical treatments that may impair biological fertility potential. Young DSD patients also often have abnormal gonadal development. Fertility preservation for these populations has historically been poorly understood and rarely addressed. Future fertility should be discussed with gender and sex diverse individuals, particularly given recent advances in fertility preservation technologies and evolving views of fertility potential. Key ethical issues include parental proxy decision-making and uncertainty regarding prepubertal fertility preservation technologies. Many opportunities exist for advancing fertility-related care and research for transgender and DSD patients.

Human factors evaluations of Free Flight Issues solved and issues remaining.

Ruigrok, Rob C J; Hoekstra, Jacco M

2007-07-01

The Dutch National Aerospace Laboratory (NLR) has conducted extensive human-in-the-loop simulation experiments in NLR's Research Flight Simulator (RFS), focussed on human factors evaluation of Free Flight. Eight years of research, in co-operation with partners in the United States and Europe, has shown that Free Flight has the potential to increase airspace capacity by at least a factor of 3. Expected traffic loads and conflict rates for the year 2020 appear to be no major problem for professional airline crews participating in flight simulation experiments. Flight efficiency is significantly improved by user-preferred routings, including cruise climbs, while pilot workload is only slightly increased compared to today's reference. Detailed results from three projects and six human-in-the-loop experiments in NLR's Research Flight Simulator are reported. The main focus of these results is on human factors issues and particularly workload, measured both subjectively and objectively. An extensive discussion is included on many human factors issues resolved during the experiments, but also open issues are identified. An intent-based Conflict Detection and Resolution (CD&R) system provides "benefits" in terms of reduced pilot workload, but also "costs" in terms of complexity, need for priority rules, potential compatibility problems between different brands of Flight Management Systems and large bandwidth. Moreover, the intent-based system is not effective at solving multi-aircraft conflicts. A state-based CD&R system also provides "benefits" and "costs". Benefits compared to the full intent-based system are simplicity, low bandwidth requirements, easy to retrofit (no requirements to change avionics infrastructure) and the ability to solve multi-aircraft conflicts in parallel. The "costs" involve a somewhat higher pilot workload in similar circumstances, the smaller look-ahead time which results in less efficient resolution manoeuvres and the sometimes false/nuisance alerts due to missing intent information. The optimal CD&R system (in terms of costs versus benefits) has been suggested to be state-based CD&R with the addition of intended or target flight level. This combination of state-based CD&R with a limited amount of intent provides "the best of both worlds". Studying this CD&R system is still an open issue.

Experiences with Cray multi-tasking

NASA Technical Reports Server (NTRS)

Miya, E. N.

1985-01-01

The issues involved in modifying an existing code for multitasking is explored. They include Cray extensions to FORTRAN, an examination of the application code under study, designing workable modifications, specific code modifications to the VAX and Cray versions, performance, and efficiency results. The finished product is a faster, fully synchronous, parallel version of the original program. A production program is partitioned by hand to run on two CPUs. Loop splitting multitasks three key subroutines. Simply dividing subroutine data and control structure down the middle of a subroutine is not safe. Simple division produces results that are inconsistent with uniprocessor runs. The safest way to partition the code is to transfer one block of loops at a time and check the results of each on a test case. Other issues include debugging and performance. Task startup and maintenance (e.g., synchronization) are potentially expensive.

Advances in biological engineering are likely to have substantial impacts on global society. To explore these potential impacts we ran a horizon scanning exercise to capture a range of perspectives on the opportunities and risks presented by biological engineering. We first identified 70 potential issues, and then used an iterative process to prioritise 20 issues that we considered to be emerging, to have potential global impact, and to be relatively unknown outside the field of biological engineering. The issues identified may be of interest to researchers, businesses and policy makers in sectors such as health, energy, agriculture and the environment.

Expanding the three Rs to meet new challenges in humane animal experimentation.

PubMed

Schuppli, Catherine A; Fraser, David; McDonald, Michael

2004-11-01

The Three Rs are the main principles used by Animal Ethics Committees in the governance of animal experimentation, but they appear not to cover some ethical issues that arise today. These include: a) claims that certain species should be exempted on principle from harmful research; b) increased emphasis on enhancing quality of life of research animals; c) research involving genetically modified (GM) animals; and d) animals bred as models of disease. In some cases, the Three Rs can be extended to cover these developments. The burgeoning use of GM animals in science calls for new forms of reduction through improved genetic modification technology, plus continued attention to alternative approaches and cost-benefit analyses that include the large numbers of animals involved indirectly. The adoption of more expanded definitions of refinement that go beyond minimising distress will capture concerns for enhancing the quality of life of animals through improved husbandry and handling. Targeting refinement to the unpredictable effects of gene modification may be difficult; in these cases, careful attention to monitoring and endpoints are the obvious options. Refinement can also include sharing data about the welfare impacts of gene modifications, and modelling earlier stages of disease, in order to reduce the potential suffering caused to disease models. Other issues may require a move beyond the Three Rs. Certain levels of harm, or numbers and use of certain species, may be unacceptable, regardless of potential benefits. This can be addressed by supplementing the utilitarian basis of the Three Rs with principles based on deontological and relational ethics. The Three Rs remain very useful, but they require thoughtful interpretation and expansion in order for Animal Ethics Committees to address the full range of issues in animal-based research.

A number of persons with an intractable disease (ID) experience work-related problems that could lead to job loss. The aim of this study was to ascertain perceptions regarding a range of work-related issues and corresponding support needs of individuals with an ID. Potential participants were people ages 15 to 64 with one of the 130 intractable chronic diseases designated in the Act to Comprehensively Support the Daily and Social Activities of Persons with Disabilities (Comprehensive Support for the Disabled Act). Participants completed a self-administered questionnaire. With the assistance of patients' organizations, 3,000 questionnaires were mailed to potential participants. Questions included demographic characteristics, family concerns, employment/supported employment, work accommodations, and other aspects of life. Responses were received from 889 (29.6%) participants, and respondents had 57 IDs. Forty-six-point-seven percent of respondents reported being unemployed due to fatigue and/or long-term treatment. Nearly half of the unemployed respondents reported that they had been unable to work despite their willingness to do so. Common requests for accommodation included flexible work hours, working at home, and job/workplace modifications. Only 30% of respondents knew about job training programs and supported work available for persons with disabilities. The results of the study are relevant for employees, employers, and occupational health/human resource professionals. The issue of reasonable accommodations for persons with an ID needs to be addressed in future research in order to promote continued work by those persons.

Risk management and post-marketing surveillance of CNS drugs.

Henningfield, Jack E; Schuster, Charles R

2009-12-01

Drugs affecting the central nervous system span a broad range of chemical entities, dosage forms, indications, and risks. Unintended consequences include potential abuse and overdose in non-patient drug abusers, deliberate tampering of drug dosage forms, and criminal behavior associated with diversion. Regulators must consider diverse factors to find the appropriate conditions of approval to minimize unintended consequences while enabling a level of access desired by health care providers and patients. This commentary appears as part of a special issue of Drug and Alcohol Dependence that focuses on risk management and post-marketing surveillance and addresses key issues that pose real-world challenges to pharmaceutical sponsors and regulators in particular. For example, in the U.S., Controlled Substances Act drug scheduling can be considered a risk management strategy but its legal authorities and administrative processes are independent from those of risk management (including Risk Evaluation and Mitigation Strategies or REMS); better harmonization of these approaches is vital from drug development and regulatory perspectives. Risk management would ideally be implemented on a strong science foundation demonstrating that the tools employed to mitigate risks and ensure safe use are effective. In reality, research and evaluation of tools in this area is in its infancy and will necessarily be an evolutionary process; furthermore, there is little precedent for linking interventions and program evolution to unintended consequences such as regional outbreaks of abuse and diversion. How such issues are resolved has the potential to stimulate or stifle innovations in drug development and advance or imperil health care.

ABodyBuilder: Automated antibody structure prediction with data–driven accuracy estimation

ABSTRACT Computational modeling of antibody structures plays a critical role in therapeutic antibody design. Several antibody modeling pipelines exist, but no freely available methods currently model nanobodies, provide estimates of expected model accuracy, or highlight potential issues with the antibody's experimental development. Here, we describe our automated antibody modeling pipeline, ABodyBuilder, designed to overcome these issues. The algorithm itself follows the standard 4 steps of template selection, orientation prediction, complementarity-determining region (CDR) loop modeling, and side chain prediction. ABodyBuilder then annotates the ‘confidence’ of the model as a probability that a component of the antibody (e.g., CDRL3 loop) will be modeled within a root–mean square deviation threshold. It also flags structural motifs on the model that are known to cause issues during in vitro development. ABodyBuilder was tested on 4 separate datasets, including the 11 antibodies from the Antibody Modeling Assessment–II competition. ABodyBuilder builds models that are of similar quality to other methodologies, with sub–Angstrom predictions for the ‘canonical’ CDR loops. Its ability to model nanobodies, and rapidly generate models (∼30 seconds per model) widens its potential usage. ABodyBuilder can also help users in decision–making for the development of novel antibodies because it provides model confidence and potential sequence liabilities. ABodyBuilder is freely available at http://opig.stats.ox.ac.uk/webapps/abodybuilder. PMID:27392298

On November 3, 2014, in Bethesda, MD, the Office of Cancer Complementary and Alternative Medicine of the National Cancer Institute held a meeting to examine the potential utility and feasibility of establishing an international consortium for Chinese medicine and cancer. There is significant interest in the West in using components of Chinese medicine (CM) —such as botanicals and herbal medicines, acupuncture and acupressure, and qigong—in the field of oncology, as potential anticancer agents, for symptom management, and to improve quality of life. The proposal for a consortium on CM came from the Chinese Academy of Chinese Medical Sciences, with the aims of improving scientific communications and collaborations and modernizing the studies of CM for cancer. The US National Cancer Institute’s Office of Cancer Complementary and Alternative Medicine agreed to work with Chinese Academy of Chinese Medical Sciences to explore the feasibility of establishing an international consortium for Chinese medicine and cancer. At the meeting, participants from the United States, China, Canada, Australia, and Korea discussed issues in CM and cancer research, treatment, and management, including potential mechanisms of action, proof of efficacy, adverse effects, regulatory issues, and the need for improving the quality of randomized clinical trials of CM treatments and supportive care interventions. Presented in these proceedings are some of the main issues and opportunities discussed by workshop participants. PMID:29244995

Technology-driven efforts to implement automation often encounter problems due to lack of acceptance or begrudging acceptance by the personnel involved. It is argued in this paper that the level of automation perceived by an individual heavily influences whether or not the automation is accepted by that individual. The factors that appear to affect perceived level of automation are discussed. Issues considered include the impact of automation on the system and the individual, correlates of acceptance, problems and risks of automation, and factors influencing alienation. Based on an understanding of these issues, a set of eight guidelines is proposed as a possible means of avoiding problems in implementing automation.

Sleep issues are common in people with psychiatric disorders, and the interaction is complex. Sleep disorders, particularly insomnia, can precede and predispose to psychiatric disorders, can be comorbid with and exacerbate psychiatric disorders, and can occur as part of psychiatric disorders. Sleep disorders can mimic psychiatric disorders or result from medication given for psychiatric disorders. Impairment of sleep and of mental health may be different manifestations of the same underlying neurobiological processes. For the primary care physician, key tools include recognition of potential sleep effects of psychiatric medications and familiarity with treatment approaches for insomnia in depression and anxiety.

Mountaineering expeditions combine a number of factors which make them potentially good analogs to the planetary exploration facet of long-duration space missions. A study of mountain climbing teams was conducted in order to evaluate the usefulness of the environment as a space analog and to specifically identify the factors and issues surrounding teamwork and 'successful' team performance in two mountaineering environments. This paper focuses on social/organizational factors, including team size and structure, leadership styles and authority structure which were found in the sample of 22 climb teams (122 individuals). The second major issue discussed is the construction of a valid performance measure in this high-risk environment.

Responding to policymakers' concerns, the Internal Revenue Service (IRS) implemented significant new hospital community benefit reporting under Schedule H of its revised Form 990, the return used by tax-exempt organizations. This issue brief considers the policy implications of the quantitative and qualitative information that hospitals are now mandated to report through Schedule H, including the costs associated with charity care, bad debt, and the unreimbursed costs of Medicaid and Medicare. The paper examines unresolved issues related to the new reporting requirements, such as controversies regarding the scope of Schedule H, and considers the potential for these reports to influence IRS oversight activities, legislative action, and hospital policies and practices.

Factors that introduce intrasubject variability into ear-canal absorbance measurements.

Voss, Susan E; Stenfelt, Stefan; Neely, Stephen T; Rosowski, John J

2013-07-01

Wideband immittance measures can be useful in analyzing acoustic sound flow through the ear and also have diagnostic potential for the identification of conductive hearing loss as well as causes of conductive hearing loss. To interpret individual measurements, the variability in test–retest data must be described and quantified. Contributors to variability in ear-canal absorbance–based measurements are described in this article. These include assumptions related to methodologies and issues related to the probe fit within the ear and potential acoustic leaks. Evidence suggests that variations in ear-canal cross-sectional area or measurement location are small relative to variability within a population. Data are shown to suggest that the determination of the Thévenin equivalent of the ER-10C probe introduces minimal variability and is independent of the foam ear tip itself. It is suggested that acoustic leaks in the coupling of the ear tip to the ear canal lead to substantial variations and that this issue needs further work in terms of potential criteria to identify an acoustic leak. In addition, test–retest data from the literature are reviewed.

Introduction for the special issue on recent advances in drug delivery across tissue barriers.

Mrsny, Randall J; Brayden, David J

2016-01-01

This special issue of Tissue Barriers contains a series of reviews with the common theme of how biological barriers established at epithelial tissues limit the uptake of macromolecular therapeutics. By improving our functional understanding of these barriers, the majority of the authors have highlighted potential strategies that might be applied to the non-invasive delivery of biopharmaceuticals that would otherwise require an injection format for administration. Half of the articles focus on the potential of particular technologies to assist oral delivery of peptides, proteins and other macromolecules. These include use of prodrug chemistry to improve molecule stability and permeability, and the related potential for oral delivery of poorly permeable agents by cell-penetrating peptides and dendrimers. Safety aspects of intestinal permeation enhancers are discussed, along with the more recent foray into drug-device combinations as represented by intestinal microneedles and externally-applied ultrasound. Other articles highlight the crossover between food research and oral delivery based on nanoparticle technology, while the final one provides a fascinating interpretation of the physiological problems associated with subcutaneous insulin delivery and how inefficient it is at targeting the liver.

Medical application of ionizing radiation is a massive and increasing activity globally. While the use of ionizing radiation in medicine brings tremendous benefits to the global population, the associated risks due to stochastic and deterministic effects make it necessary to protect patients from potential harm. Current issues in radiation protection of patients include not only the rapidly increasing collective dose to the global population from medical exposure, but also that a substantial percentage of diagnostic imaging examinations are unnecessary, and the cumulative dose to individuals from medical exposure is growing. In addition to this, continued reports on deterministic injuries from safety related events in the medical use of ionizing radiation are raising awareness on the necessity for accident prevention measures. The International Atomic Energy Agency is engaged in several activities to reverse the negative trends of these current issues, including improvement of the justification process, the tracking of radiation history of individual patients, shared learning of safety significant events, and the use of comprehensive quality audits in the clinical environment.

Comprehensive design requirements associated with designing habitats for humans in a partial gravity environment were investigated and then applied to a lunar base design. Other potential sites for application include planetary surfaces such as Mars, variable gravity research facilities, or a rotating spacecraft. Design requirements for partial gravity environments include: (1) locomotion changes in less than normal Earth gravity; (2) facility design issues, such as interior configuration, module diameter and geometry; and (3) volumetric requirements based on the previous as well as psychological issues involved in prolonged isolation. For application to a Lunar Base, it was necessary to study the exterior architecture and configuration to insure optimum circulation patterns while providing dual egress. Radiation protection issues were addressed to provide a safe and healthy environment for the crew, and finally, the overall site was studied to locate all associated facilities in context with the habitat. Mission planning was not the purpose of this study; therefore, a Lockheed scenario was used as an outline for the Lunar Base application, which was then modified to meet the project needs.

Prescription opioid abuse, pain and addiction: clinical issues and implications.

Ling, Walter; Mooney, Larissa; Hillhouse, Maureen

2011-05-01

Prescription opioid misuse in the USA has increased over threefold since 1990 to epidemic proportions, with substantial increases in prescription opioid use also reported in other countries, such as Australia and New Zealand. The broad availability of prescription pain medications, coupled with public misconceptions about their safety and addictive potential, have contributed to the recent surge in non-medical use of prescription opioids and corresponding increases in treatment admissions for problems related to opioid misuse. Given competing pressures faced by physicians to both diagnose and treat pain syndromes and identify individuals at risk for addictive disorders, the use of opioids in the treatment of pain poses a significant clinical challenge. This paper reviews the interaction between pain and opioid addiction with a focus on clinical management issues, including risk factors for opioid dependence in patients with chronic pain and the use of assessment tools to identify and monitor at-risk individuals. Treatment options for opioid dependence and pain are reviewed, including the use of the partial µ agonist buprenorphine in the management of concurrent pain and opioid addiction. Physicians should strive to find a reasonable balance between minimising potential adverse effects of opioid medications without diminishing legitimate access to opioids for analgesia. The article discusses the need to identify methods for minimising risks and negative consequences associated with opioid analgesics and poses research directions, including the development of abuse-deterrent opioid formulations, genetic risk factors for opioid dependence and opioid-induced hyperalgesia as a potential target for medication therapy. © 2011 Australasian Professional Society on Alcohol and other Drugs.

The growing role of biologics and biosimilars in the United States: Perspectives from the APhA Biologics and Biosimilars Stakeholder Conference.

PubMed

Crespi-Lofton, Judy; Skelton, Jann B

The American Pharmacists Association (APhA) convened the Biologics and Biosimilars Stakeholder Conference on November 30, 2016, in Washington DC. The objectives of the Conference were to determine the key issues and challenges within the marketplace for biologics, follow-on biologics (FOBs), and biosimilars, identify potential roles and responsibilities of pharmacists regarding biologic and biosimilar medications, and identify actions or activities that pharmacists may take to optimize the safe and cost-effective use of biologics and biosimilars. National thought leaders and stakeholder representatives, including individuals from the Food and Drug Administration, Centers for Medicare and Medicaid Services, a private third-party payer, manufacturers, and several national organizations of health care professionals, participated in the conference. Information shared by this group was supplemented with relevant legal and regulatory information and published literature. Biologics play a valuable role in the treatment of numerous health conditions, but their associated costs, which tend to be greater than those of small-molecule drugs, place a burden on the health care system. Biosimilars (both noninterchangeable and interchangeable) are highly similar copies of the originator biologic and offer the potential to reduce costs and improve patient access to biological products by increasing treatment options and creating a more competitive market. Despite the potential benefits of biosimilars, certain factors may limit their uptake. The conference participants explored issues that different stakeholders think influence the use of biologics, including biosimilars, in the United States. Barriers included technology, prescriber-pharmacist communication, legislation and regulations, limited patient and health care practitioner knowledge of biological products, patient and health care practitioner perceptions of biosimilars, and evolving science or lack of long-term data. After participants identified issues, they discussed strategies to address these concerns, including the need to enhance the education of pharmacists, prescribers, and patients regarding biologic products, including biosimilars and FOBs; the passage of state laws and regulations that do not impede the use of biosimilars, including interchangeable biosimilars; the use of product-specific tracking information in electronic health records and surveillance systems; bidirectional communication among pharmacists, prescribers, and other members of the care team to support pharmacovigilance and the maintenance of accurate patient records; and the development of evidence-based third-party payer policies. Patient access to safe and cost-effective treatments is an important goal for the health care system. As the availability and use of biosimilars, including those determined to be interchangeable, increases, their potential to lower costs and improve patient access to treatment grows. However, the extent of such growth is, in part, dependent on various stakeholders' decisions to provide, pay for, or use these products in a safe and thoughtful manner.

Continuous Codes and Standards Improvement (CCSI)

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

Rivkin, Carl H; Burgess, Robert M; Buttner, William J

2015-10-21

As of 2014, the majority of the codes and standards required to initially deploy hydrogen technologies infrastructure in the United States have been promulgated. These codes and standards will be field tested through their application to actual hydrogen technologies projects. Continuous codes and standards improvement (CCSI) is a process of identifying code issues that arise during project deployment and then developing codes solutions to these issues. These solutions would typically be proposed amendments to codes and standards. The process is continuous because as technology and the state of safety knowledge develops there will be a need to monitor the applicationmore » of codes and standards and improve them based on information gathered during their application. This paper will discuss code issues that have surfaced through hydrogen technologies infrastructure project deployment and potential code changes that would address these issues. The issues that this paper will address include (1) setback distances for bulk hydrogen storage, (2) code mandated hazard analyses, (3) sensor placement and communication, (4) the use of approved equipment, and (5) system monitoring and maintenance requirements.« less

In 1996, the Federal Energy Regulatory Commission (FERC) issued Order 888, which required transmission-owning utilities under FERC jurisdiction to provide open access transmission service to eligible wholesale power customers. Among other things, the elements of electric service are unbundled, meaning that wind project developers must not only find a taker for the energy but also potentially make interconnection, ancillary service, and transmission arrangements for their wind projects. In 1999, the FERC issued Order 2000, which required transmission-owning utilities to file an intent with FERC on whether they have joined or plan to join a regional transmission organization (RTO). Order 2000more » also required RTOs to meet certain criteria and be approved by FERC in order to begin operations as an RTO. More recently, FERC said it would issue a Notice of Proposed Rulemaking in 2002 on certain requirements and services, often termed''standard market design'' (SMD), that must be included in all transmission tariffs filed at FERC. This paper discusses the chronology of open access transmission issues, from Order 888 onward, and reviews some of the important issues raised by FERC's SMD initiative.« less

Civil Legal Services and Medical-Legal Partnerships Needed by the Homeless Population: A National Survey.

PubMed

Tsai, Jack; Jenkins, Darlene; Lawton, Ellen

2017-03-01

To examine civil legal needs among people experiencing homelessness and the extent to which medical-legal partnerships exist in homeless service sites, which promote the integration of civil legal aid professionals into health care settings. We surveyed a national sample of 48 homeless service sites across 26 states in November 2015. The survey asked about needs, attitudes, and practices related to civil legal issues, including medical-legal partnerships. More than 90% of the homeless service sites reported that their patients experienced at least 1 civil legal issue, particularly around housing, employment, health insurance, and disability benefits. However, only half of all sites reported screening patients for civil legal issues, and only 10% had a medical-legal partnership. The large majority of sites reported interest in receiving training on screening for civil legal issues and developing medical-legal partnerships. There is great need and potential to deploy civil legal services in health settings to serve unstably housed populations. Training homeless service providers how to screen for civil legal issues and how to develop medical-legal partnerships would better equip them to provide comprehensive care.

Shale gas resource potential in China is assessed to be large, and its development could have wide-ranging economic, environmental, and energy security implications. Although commercial scale shale gas development has not yet begun in China, it holds the potential to change the global energy landscape. Chinese decision-makers are wrestling with the challenges associated with bringing the potential to reality: geologic complexity; infrastructure and logistical difficulties; technological, institutional, social and market development issues; and environmental impacts, including greenhouse gas emissions, impacts on water availability and quality, and air pollution. This paper briefly examines the current situation and outlook for shale gasmore » in China, and explores existing and potential avenues for international cooperation. We find that despite some barriers to large-scale development, Chinese shale gas production has the potential to grow rapidly over the medium-term.« less

Bridging the Divide between Safety and Risk Management for your Project or Program

NASA Technical Reports Server (NTRS)

Lutomski, Mike

2005-01-01

This presentation will bridge the divide between these separate but overlapping disciplines and help explain how to use Risk Management as an effective management decision support tool that includes safety. Risk Management is an over arching communication tool used by management to prioritize and effectively mitigate potential problems before they concur. Risk Management encompasses every kind of potential problem that can occur on a program or project. Some of these are safety issues such as hazards that have a specific likelihood and consequence that need to be controlled and included to show an integrated picture of accepted) mitigated, and residual risk. Integrating safety and other assurance disciplines is paramount to accurately representing a program s or projects risk posture. Risk is made up of several components such as technical) cost, schedule, or supportability. Safety should also be a consideration for every risk. The safety component can also have an impact on the technical, cost, and schedule aspect of a given risk. The current formats used for communication of safety and risk issues are not consistent or integrated. The presentation will explore the history of these disciplines, current work to integrate them, and suggestions for integration for the future.

Improvement Science Meets Improvement Scholarship: Reframing Research for Better Healthcare.

PubMed

Cribb, Alan

2018-06-01

In this editorial essay I explore the possibilities of 'improvement scholarship' in order to set the scene for the theme of, and the other papers in, this issue. I contrast a narrow conception of quality improvement (QI) research with a much broader and more inclusive conception, arguing that we should greatly extend the existing dialogue between 'problem-solving' and 'critical' currents in improvement research. I have in mind the potential for building a much larger conversation between those people in 'improvement science' who are expressly concerned with tackling the problems facing healthcare and the wider group of colleagues who are engaged in health-related scholarship but who do not see themselves as particularly interested in quality improvement, indeed who may be critical of the language or concerns of QI. As one contribution to that conversation I suggest that that the increasing emphasis on theory and rigour in improvement research should include more focus on normative theory and rigour. The remaining papers in the issue are introduced including the various ways in which they handle the 'implicit normativity' of QI research and practice, and the linked theme of combining relatively 'tidy' and potentially 'unruly' forms of knowledge.

The Environmental Health/Home Safety Education Project (Proyecto de Salud Ambiental y Seguridad en el Hogar) has been developed in response to a wide array of severe and often preventable environmental health issues occurring in and around homes on the U.S.-Mexico border. Utilizing well-trained community members, called promotoras , homes are visited and assessed for potential environmental hazards, including home fire and food safety issues. Data analyzed from project years 2002 to 2005 shows a significant impact in knowledge levels and initial behavior change among targeted participants as it relates to fire and food safety issues. Since the initiation of the project in 1999, hundreds of participants have improved their quality of life by making their homes safer. The project has proven to be sustainable, replicable, flexible, and attractive to funders.

Key Issues Concerning Biolog Use for Aerobic and Anaerobic Freshwater Bacterial Community-Level Physiological Profiling

NASA Astrophysics Data System (ADS)

Christian, Bradley W.; Lind, Owen T.

2006-06-01

Bacterial heterotrophy in aquatic ecosystems is important in the overall carbon cycle. Biolog MicroPlates provide information into the metabolic potential of bacteria involved in carbon cycling. Specifically, Biolog EcoPlatesTM were developed with ecologically relevant carbon substrates to allow investigators to measure carbon substrate utilization patterns and develop community-level physiological profiles from natural bacterial assemblages. However, understanding of the functionality of these plates in freshwater research is limited. We explored several issues of EcoPlate use for freshwater bacterial assemblages including inoculum density, incubation temperature, non-bacterial color development, and substrate selectivity. Each of these has various effects on plate interpretation. We offer suggestions and techniques to resolve these interpretation issues. Lastly we propose a technique to allow EcoPlate use in anaerobic freshwater bacterial studies.

Epidemics have the potential to severely strain intensive care resources and may require an increase in intensive care capability. Few intensivists have direct experience of rapidly expanding intensive care services in response to an epidemic. This contribution presents the recommendations of an expert group from Hong Kong and Singapore who had direct experience of expanding intensive care services in response to the epidemic of severe acute respiratory syndrome. These recommendations cover training, infection control, staffing, communication and ethical issues. The issue of what equipment to purchase is not addressed. Early preparations should include fit testing of negative pressure respirators, training of reserve staff, sourcing of material for physical modifications to the ICU, development of infection control policies and training programmes, and discussion of triage and quarantine issues.

Social networking sites (SNS) are now part of everyday life, and SNSs such as Facebook, YouTube, and Twitter are among the most accessed Web sites on the Internet. Although SNSs are primarily used for staying in touch with friends and family, they are increasingly being used for health-related purposes for a variety of conditions, including concussion awareness. As health interventions begin to be more commonly provided through SNSs (particularly Facebook), ethical issues have been raised with regard to confidentiality, privacy, and trust; these issues need to be addressed. This article outlines some of the key considerations when providing a concussion intervention through Facebook and discusses potential solutions to these issues.

Nursing research: can a feminist perspective make any contribution?

PubMed

Ehlers, V

1999-03-01

As more than 90% of the RSA's nurses are women and as at least 50% of the health care clients are also women, nursing research can definitely benefit by incorporating feminist research approaches. Specific feminist research issues which could be relevant to nursing research include: inherent themes in feminist research feminist research methodology gender stereotypes and nursing research gender-based stereotypes of researchers potential benefits of incorporating feminist research approaches in nursing research. Most formal models of nursing, and thus also most nursing research based on these models, ignore gender issues. Thus they ignore part of the social reality of nursing and might provide distorted images of nursing. A feminist approach to nursing research could enhance the reality-based gender issues relevant to nursing specifically, and health care generally, and contribute towards rendering effective health care within a multidisciplinary health care context.

Attending to scalar ethical issues in emerging approaches to environmental health research and practice.

PubMed

Buse, Chris G; Smith, Maxwell; Silva, Diego S

2018-06-04

Accelerated changes to the planet have created novel spaces to re-imagine the boundaries and foci of environmental health research. Climate change, mass species extinction, ocean acidification, biogeochemical disturbance, and other emergent environmental issues have precipitated new population health perspectives, including, but not limited to, one health, ecohealth, and planetary health. These perspectives, while nuanced, all attempt to reconcile broad global challenges with localized health impacts by attending to the reciprocal relationships between the health of ecosystems, animals, and humans. While such innovation is to be encouraged, we argue that a more comprehensive engagement with the ethics of these emerging fields of inquiry will add value in terms of the significance and impact of associated interventions. In this contribution, we highlight how the concept of spatial and temporal scale can be usefully deployed to shed light on a variety of ethical issues common to emerging environmental health perspectives, and that the potential of scalar analysis implicit to van Potter's conceptualization of bioethics has yet to be fully appreciated. Specifically, we identify how scale interacts with key ethical issues that require consideration and clarification by one health, ecohealth, and planetary health researchers and practitioners to enhance the effectiveness of research and practice, including justice and governance.

Informed Consent for Electroconvulsive Therapy--Finding Balance.

PubMed

Mankad, Mehul

2015-09-01

Informed consent underpins all medical decisions, including the decision to undergo electroconvulsive therapy (ECT). Written informed consent remains the standard before the initiation of ECT and requires the inclusion of several components to be considered valid. Prospective patients must be aware of risks and benefits of ECT as well as risks and benefits of alternate, and potentially less effective, interventions. Patients must also possess adequate decision-making capacity to make an informed choice about treatment. Consent for ECT may present unique issues, such as the interplay between potential cognitive adverse effects and informed consent. Options to address this concern include thorough explanation of this topic before the initiation of ECT, continued reassessment of consent during ECT, or some combination of approaches.

2015-03-01

Brain-computer interfaces (BCIs) may potentially be of significant practical value to patients in advanced stages of amyotrophic lateral sclerosis and locked-in syndrome for whom conventional augmentative and alternative communication (AAC) systems, which require some measure of consistent voluntary muscle control, are not satisfactory options. However, BCIs have primarily been used for communication in laboratory research settings. This article discusses 4 critical issues that should be addressed as BCIs are translated out of laboratory settings to become fully functional BCI/AAC systems that may be implemented clinically. These issues include (1) identification of primary, secondary, and tertiary system features; (2) integrating BCI/AAC systems in the World Health Organization's International Classification of Functioning, Disability and Health framework; (3) implementing language-based assessment and intervention; and (4) performance measurement. A clinical demonstration project is presented as an example of research beginning to address these critical issues. Copyright © 2015 American Congress of Rehabilitation Medicine.

At the conclusion of a nearly four year study cycle following the closing of the 2012 World Radiocommunication Conference (WRC-12), the 2015 WRC in November of 2015 considered a number of agenda items and issues relevant to systems and spectrum allocations supporting communications, navigation and surveillance for the operation of civil aviation. Among a number of WRC-15 agenda items and issues, the key agenda items affecting civil aviation included: unmanned aircraft systems use of the Fixed Satellite Service for command and control communications; global flight tracking; new allocations to International Mobile Telecommunications (IMT); and protection of the Fixed Satellite Service to support safe operation of aircraft. A number of other agenda items affecting or potentially affecting civil aviation were also addressed by WRC-15. In this paper we describe the outcomes of WRC-15 for these civil aeronautical-relevant issues. We then outline the civil aviation-related agenda items and issues that will be considered at the upcoming 2019 WRC.

Saudi Science Teachers' Views and Teaching Strategies of Socioscientific Issues

Alamri, Aziz S.

Scientific developments such as cloning and nuclear energy have generated many controversial issues pertain to many political, social, environmental, ethical and cultural values in different societies around the globe. These controversies delimited and encircled the potential of including and teaching some important aspects of science in schools and therefore caused less consideration to the influence of these issues on enhancing the scientific literacy of people in general. The purpose of this study was to investigate how Saudi science teachers in the city of Tabuk in Saudi Arabia view and teach SSI in Saudi Arabia. This study employed semi-structured interviews with Saudi science teachers. Methodologically, this study used a constructivist grounded theory as a method for analysis to generate in-depth descriptive data about Saudi science teachers' views and teaching strategies of socio-scientific issues. Some direct and indirect benefits pertain to teaching science, understanding the relationship between science, religion, and society and some other topics are discussed in this study.

Healing the incest wound: a treatment update with attention to recovered-memory issues.

PubMed

Courtois, C A

1997-01-01

This article provides an updated treatment model for adults who report having experienced incestuous abuse in childhood. It integrates psychodynamic, traumatic stress, developmental and feminist formulations, accords greater emphasis to object relations and self-psychology perspectives, includes more attention to dissociative reactions, and utilizes more cognitive-behavioral interventions. It is also responsive to issues raised in the recovered/false memory controversy. This holistic model is sequenced, paced, and titrated according to the patient's characterological structure, ego strength, and needs as well as the range and severity of presenting problems and life difficulties. Special consideration is given to issues pertaining to memory and the maintenance of a neutral stance by the therapist, especially in the case of recovered rather than continuous memories and/or suspicions rather than actual knowledge of abuse. Contemporary perspectives regarding some of the unique transference, countertransference, and vicarious traumatization issues with this population and their potential impact on treatment are also discussed.

2017-11-26

The 2016 World Cancer Congress, organised by UICC, was held in Paris in November 2016, under the theme “Mobilizing action – Inspiring Change.” As part of Track 4 presentations on the theme of “Strengthening cancer control: optimizing outcomes of health systems,” UICC-Asian Regional Office (UICC-ARO) held a symposium to discuss the issue of mobilizing action to realize UHC in Asia. Introducing the symposium, Hideyuki Akaza noted that universal health coverage (UHC) is included in the Sustainable Development Goals and one of the key issues for achieving UHC will be how to balance patient needs with the economic burden of cancer. Speakers from Japan and Indonesia addressed various issues, including the current status and challenges for medical economic evaluation in Asia, the importance of resource stratification, prospects for precision medicine, and the outlook for cancer control and UHC in developing and emerging countries in Asia. Key issues raised included how to respond to the rising costs of treating cancer as new and increasingly expensive drugs come to the market. Speakers and participants noted that health technology assessment programs are being developed around Asia in order to evaluate the cost-effectiveness of drugs in the face of budgetary constraints within increasingly pressurized national health systems. The importance of screening and early detection was also noted as effective means that have the potential to reduce reliance on expensive drugs for advanced cancers. The symposium was chaired jointly by Hideyuki Akaza and Shinjiro Nozaki (WHO Kobe Centre). Creative Commons Attribution License

In 1983, an FAA-sponsored National Rotorcraft Program sought to identify improvements to the national interurban transportation networks and determined that conventional helicopters did not have the potential to satisfy requirements because of a lack of capacity, high operational costs, and high noise levels. Tiltrotors, it was felt offered a better potential to improve interurban air transport service. In 1985, the FAA proposed a joint civil tiltrotor study with NASA and DOD that would capitalize on development of the military V-22 tiltrotor and document the potential of the commercial tiltrotor transport market. The results of a study on the mission and application of a civil tiltrotor is presented. This study addresses national issues and includes a market summary. A technical summary provides information on six design configurations and potential risk areas are identified. The development of a National Plan for a tiltrotor transportation system is recommended including civil tiltrotor technology development, infrastructure planning and development, a flight technology demonstration plan, and near term actions.

2016-07-21

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.

[Energy drinks and their contribution to current health concerns for children and adolescents].

PubMed

Cichocki, Michał

2012-01-01

Carbonated beverages including energy drinks make up an increasing percentage of energy intake amongst adults as well as children and adolescents. Due to high content of di- or monosaccharides and biologically active compounds (mainly caffeine), their regular intake may involve addictions and potential health risks, including diabetes. Although consumption of energy drinks is usually not recommended by the manufacturers to the children under the age of 16, due to its popularity and unrestricted availability on market energy drinks are easily accessible to younger children. Low awareness of the potential health risks involved with such beverages in society together with unrestricted distribution and advertising requires undertaking general information campaign concerning energy drinks. In this paper a critical review has been made to discuss potential somatic and psychological health risks issue. Moreover, conclusions were supported with the results of the survey conducted among college and high-school adolescents.

High volume hydraulic fracturing operations: potential impacts on surface water and human health.

PubMed

Mrdjen, Igor; Lee, Jiyoung

2016-08-01

High volume, hydraulic fracturing (HVHF) processes, used to extract natural gas and oil from underground shale deposits, pose many potential hazards to the environment and human health. HVHF can negatively affect the environment by contaminating soil, water, and air matrices with potential pollutants. Due to the relatively novel nature of the process, hazards to surface waters and human health are not well known. The purpose of this article is to link the impacts of HVHF operations on surface water integrity, with human health consequences. Surface water contamination risks include: increased structural failure rates of unconventional wells, issues with wastewater treatment, and accidental discharge of contaminated fluids. Human health risks associated with exposure to surface water contaminated with HVHF chemicals include increased cancer risk and turbidity of water, leading to increased pathogen survival time. Future research should focus on modeling contamination spread throughout the environment, and minimizing occupational exposure to harmful chemicals.

Social inclusion of the people with mental health issues: Compare international results.

Santos, Jussara Carvalho Dos; Barros, Sônia; Huxley, Peter John

2018-06-01

Social inclusion of people with mental health issues is an aim of the World Health Organisation. Many countries have adopted that objective, including Brazil and the United Kingdom and both have focused treatment in the community. The aim of this article is to compare international results using the same inclusion instrument. The samples in this study were 225 people with mental health issues in community services in São Paulo, Brazil. Their results are compared to findings from 168 people with similar mental health issues in Hong Kong, China, and from the United Kingdom - a nationally representative sample of 212 people without mental health issues. The instrument used to measure a social inclusion called Social and Communities Opportunities Profile (SCOPE) has been validated for use in the United Kingdom, China and Brazil. The results are that people with mental health issues have worse social inclusion when compared to general population. Between the people with mental health issues, the sample of São Paulo has the lowest social inclusion index but, in relation to access to the Brazilian revised mental health services, that sample has a similarly high inclusion rating to the general population of the United Kingdom. Findings are important to understand mental health in the community context, as well as their adversities and potentialities.

Advances in biological engineering are likely to have substantial impacts on global society. To explore these potential impacts we ran a horizon scanning exercise to capture a range of perspectives on the opportunities and risks presented by biological engineering. We first identified 70 potential issues, and then used an iterative process to prioritise 20 issues that we considered to be emerging, to have potential global impact, and to be relatively unknown outside the field of biological engineering. The issues identified may be of interest to researchers, businesses and policy makers in sectors such as health, energy, agriculture and the environment. PMID:29132504

Health researchers undertake studies which combine qualitative and quantitative methods. Little attention has been paid to the structural issues affecting this mixed methods approach. We explored the facilitators and barriers to undertaking mixed methods studies in health research. Face-to-face semi-structured interviews with 20 researchers experienced in mixed methods research in health in the United Kingdom. Structural facilitators for undertaking mixed methods studies included a perception that funding bodies promoted this approach, and the multidisciplinary constituency of some university departments. Structural barriers to exploiting the potential of these studies included a lack of education and training in mixed methods research, and a lack of templates for reporting mixed methods articles in peer-reviewed journals. The 'hierarchy of evidence' relating to effectiveness studies in health care research, with the randomised controlled trial as the gold standard, appeared to pervade the health research infrastructure. Thus integration of data and findings from qualitative and quantitative components of mixed methods studies, and dissemination of integrated outputs, tended to occur through serendipity and effort, further highlighting the presence of structural constraints. Researchers are agents who may also support current structures - journal reviewers and editors, and directors of postgraduate training courses - and thus have the ability to improve the structural support for exploiting the potential of mixed methods research. The environment for health research in the UK appears to be conducive to mixed methods research but not to exploiting the potential of this approach. Structural change, as well as change in researcher behaviour, will be necessary if researchers are to fully exploit the potential of using mixed methods research.

Since 1990 mortality and morbidity decline has been more extensive for some conditions prevalent in low- and middle-income countries than for others. One reason may be differences in the effectiveness of global health networks, which have proliferated in recent years. Some may be more capable than others in attracting attention to a condition, in generating funding, in developing interventions and in convincing national governments to adopt policies. This article introduces a supplement on the emergence and effectiveness of global health networks. The supplement examines networks concerned with six global health problems: tuberculosis (TB), pneumonia, tobacco use, alcohol harm, maternal mortality and newborn deaths. This article presents a conceptual framework delineating factors that may shape why networks crystallize more easily surrounding some issues than others, and once formed, why some are better able than others to shape policy and public health outcomes. All supplement papers draw on this framework. The framework consists of 10 factors in three categories: (1) features of the networks and actors that comprise them, including leadership, governance arrangements, network composition and framing strategies; (2) conditions in the global policy environment, including potential allies and opponents, funding availability and global expectations concerning which issues should be prioritized; (3) and characteristics of the issue, including severity, tractability and affected groups. The article also explains the design of the project, which is grounded in comparison of networks surrounding three matched issues: TB and pneumonia, tobacco use and alcohol harm, and maternal and newborn survival. Despite similar burden and issue characteristics, there has been considerably greater policy traction for the first in each pair. The supplement articles aim to explain the role of networks in shaping these differences, and collectively represent the first comparative effort to understand the emergence and effectiveness of global health networks.

There is a growing need to develop online services for university students with the capacity to complement existing services and efficiently address student mental health problems. Previous research examining the development and acceptability of online interventions has revealed that issues such as privacy critically impact user willingness to engage with these services. To explore university student perspectives on privacy issues related to using an online mental health service within the context of the development of an online, university-based virtual mental health clinic. There were two stages of data collection. The first stage consisted of four 1.5-hour focus groups conducted with university students (n=19; 10 female, 9 male, mean age = 21.6 years) to determine their ideas about the virtual clinic including privacy issues. The second stage comprised three 1-hour prototype testing sessions conducted with university students (n=6; 3 male, 3 female, mean age = 21.2 years) using participatory design methods to develop and refine a service model for the virtual clinic and determine student views on privacy within this context. The students raised a number of issues related to privacy in relation to the development of the university virtual clinic. Major topics included the types of personal information they would be willing to provide (minimal information and optional mental health data), concern about potential access to their personal data by the university, the perceived stigma associated with registering for the service, and privacy and anonymity concerns related to online forums contained within the virtual clinic. Students would be more comfortable providing personal information and engaging with the virtual clinic if they trust the privacy and security of the service. Implications of this study include building the clinic in a flexible way to accommodate user preferences.

Music Therapy and Spiritual Care in End-of-Life: A Qualitative Inquiry into Ethics and Training Issues Identified by Chaplains and Music Therapists.

Masko, Meganne K

2016-01-01

Music therapists are increasingly employed by hospices. As such, they are often called upon to provide additional spiritual care to patients receiving end-of-life care. However, researchers have not yet examined the appropriateness of music therapists providing spiritual care as part of the hospice team, or ethics and training issues related to music therapist-led spiritual care. The purpose of this study was to explore the thoughts and attitudes of hospice chaplains and music therapists (MTs) about ethics and training issues related to music therapists providing spiritual care as part of the hospice interdisciplinary team. The study used semi-structured interviews with a purposive sample of music therapists and chaplains specializing in hospice care as part of a larger exploratory mixed methods study. Each interview was recorded, transcribed, and analyzed using a two-step process including both a modified phenomenological inductive approach and thematic analysis. Participants discussed ethics and training issues related to the provision of music therapist-led spiritual care as part of the hospice team. These issues included scope of practice, cultural competence and maintaining personal boundaries, and spiritual care training topics such as educational content and educational methods. While it was clear that both chaplains and music therapists felt it was appropriate for music therapists to provide spiritual care as part of the hospice team, there is a need for formal and informal spiritual care training for music therapists doing this type of work. Training should potentially include information about comparative religions, cultural competence, scope of practice, and maintaining personal boundaries. © the American Music Therapy Association 2016.

Temporal trends and stationarity in annual peak flow and peak-flow timing for selected long-term streamflow-gaging stations in or near Montana through water year 2011: Chapter B in Montana StreamStats

The two low-elevation gaging stations in eastern Montana (Poplar River at international boundary [gaging station 06178000] and Powder River at Moorhead, Montana [gaging station 06324500]) had considerable changes in annual-peakflow characteristics after the mid-1970s, which might provide evidence of potential nonstationarity in the peak-flow records. The two low-elevation gaging stations that have potential nonstationarity are located in drainage basins that are strongly affected by agricultural activities that potentially affect the hydrologic regimes. Primary agricultural activities that might alter natural hydrologic conditions include construction of small impoundments (primarily for stock-watering purposes) and irrigation diversions. Temporal variability in these activities might contribute to the potential nonstationarity issues. Changes in climatic characteristics after the mid-1970s also possibly contribute to the potential nonstationarity issues. Lack of considerable indication of potential nonstationarity in annual peak flow for the other long-term gaging stations in this study might indicate that climatic changes have been more pronounced with respect to effects on peak flows in low elevation areas in eastern Montana than in areas represented by the other long-term gaging stations. Another possibility is that climatic changes after the mid-1970s are exacerbated in low-elevation areas where small-impoundment development and potential effects of irrigation diversions might be more extensive.

Prosperity Games are an outgrowth and adaptation of move/countermove and seminar War Games. Prosperity Games are simulations that explore complex issues in a variety of areas including economics, politics, sociology, environment, education and research. These issues can be examined from a variety of perspectives ranging from a global, macroeconomic and geopolitical viewpoint down to the details of customer/supplier/market interactions in specific industries. All Prosperity Games are unique in that both the game format and the player contributions vary from game to game. This report documents the Environmental Prosperity Game conducted under the sponsorship of the Silicon Valley Environmental Partnership. Playersmore » were drawn from all stakeholders involved in environmental technologies including small and large companies, government, national laboratories, universities, environmentalists, the legal profession, finance, and the media. The primary objectives of this game were to: investigate strategies for developing a multi-agency (national/state/regional), one-step regulatory approval process for certifying and implementing environmental technologies and evaluating the simulated results; identify the regulatory hurdles and requirements, and the best approaches for surmounting them; identify technical problems and potential resources (environmental consultants, labs, universities) for solving them. The deliberations and recommendations of these players provided valuable insights as to the views of this diverse group of decision makers concerning environmental issues, including the development, licensing, and commercialization of new technologies.« less

Mitigating Adverse Effects of a Human Mission On Possible Martian Indigenous Ecosystems

NASA Technical Reports Server (NTRS)

Lupisella, Mark L.

2000-01-01

Although human beings are, by most standards, the most capable agents to search for and detect extraterrestrial life, we are also potentially the most harmful. While there has been substantial work regarding forward contamination with respect to robotic missions, the issue of potential adverse effects on possible indigenous Martian ecosystems, such as biological contamination, due to a human mission has remained relatively unexplored and may require our attention now as this presentation will try to demonstrate by exploring some of the relevant scientific questions, mission planning challenges, and policy issues. An informal, high-level mission planning decision tree will be discussed and is included as the next page of this abstract. Some of the questions to be considered are: To what extent could contamination due to a human presence compromise possible indigenous life forms? To what extent can we control contamination? For example, will it be local or global? What are the criteria for assessing the biological status of Mars, both regionally and globally? For example, can we adequately extrapolate from a few strategic missions such as sample return missions? What should our policies be regarding our mission planning and possible interaction with what are likely to be microbial forms of extraterrestrial life? Central to the science and mission planning issues is the role and applicability of terrestrial analogs, such as Lake Vostok for assessing drilling issues, and modeling techniques. Central to many of the policy aspects are scientific value, international law, public concern, and ethics. Exploring this overall issue responsibly requires an examination of all these aspects and how they interrelate.

Managing the integration and harmonization of national airspace for unmanned and manned systems

NASA Astrophysics Data System (ADS)

Mumm, Hans

This dissertation examines the leadership challenge created by the requirement to integrate unmanned aerial vehicles (UAVs) into the national airspace system (NAS). The lack of UAV-related federal rules and regulations is a primary factor prolonging this integration. This effort focuses primarily on the leadership portion of the solution and not the technological requirements. The research explores an adaptation of the complexity theory that offers a potential leadership framework for the government, industry, and academia to use for achieving the full integration of UAVs into the NAS. Due to the large number of stakeholders and the multitude of interrelated issues, a complexity-theory-leadership methodology was created and examined as a potential way to help the FAA accelerate their rule-making efforts. This dissertation focuses on United States UAV issues. The United States is one of the leaders in the unmanned systems arena, to include the first significant use of recoverable autonomous weaponized systems in combat. Issues such as airspace, airworthiness, social issues, privacy issues, regulations, and the lack of policies, procedures, or governance are universal for all countries that are active in this technology area. This qualitative dissertation makes use of the grounded theory methodology as it combines a literature review and research along with interviews with subject matter experts, and information gained from attending UAV related gatherings/discussions. The investigation uncovered significant FAA process impediments as well as some possible break through concepts that could work well with the complexity-theory-leadership methodology. Keywords: Complexity theory, leadership, change management, UAV, unmanned aerial vehicle, National Airspace, NAS, FAA, Federal Aviation Administration.

Factors Influencing Professional Help-Seeking for Suicidality.

Evidence suggests that the majority of people with suicidality do not seek help. Little systematic evaluation of factors influencing professional help-seeking has been done. To systematically evaluate the factors that influence professional help-seeking for suicidality. Published quantitative and qualitative studies in Medline and PsycInfo databases were reviewed following PRISMA. In all, 55 relevant studies were identified. Of these, 15 studies examined professional help-seeking intentions for perceived suicidal ideation, among people with or without suicidality; 21 studies examined professional help-seeking behavior among people with suicidality; and 19 studies examined suicidal decedents' health services use. Several potential important barriers were identified including high self-reliance, lack of perceived need for treatment, and stigmatizing attitudes toward suicide, toward mental health issues, and toward seeking professional treatment. The presence of suicidality and mental health issues was found to generally decrease help-seeking intentions for perceived suicidal ideation while facilitating actual service use. Social support and informal support from family and friends also played an important role in professional help-seeking. Although the majority of the included studies were of sound quality, some of the factors identified in the review were assessed in relatively few studies, and most of the included studies were conducted in industrialized countries. Further quantitative and qualitative studies examining the potential important factors in broader community samples, especially in developing countries, are needed.

Introduction of the pill and its impact.

PubMed

Tyrer, L

1999-01-01

Introduction of the birth control pill in the United States in 1960 marked the end of a relatively short period of time (< 10 years) to intentionally produce an oral contraceptive, and the beginning of a relatively long period of controversy surrounding the use of the pill. Availability of the pill had an impact on various aspects of social life, including women's health, fertility trends, laws and policies, religion, interpersonal relationships and family roles, feminist issues, and gender relations, as well as sexual practices among both adults and adolescents. The pill proved to be highly effective from the outset. Although safety issues developed with the earlier formulations, continued evolution of pill hormones and doses has resulted in a greatly improved and safe oral contraceptive. A broad range of noncontraceptive health benefits also is associated with the pill. These health effects are significant, as they include protection against potentially fatal diseases, including ovarian and endometrial cancers, as well as against other conditions that are associated with substantial morbidity and potential hospitalization and associated costs. The popularity of the pill has remained high, with rates of use in the past 30 years in the United States ranging from one-quarter to almost one-third of women using contraception. Almost 40 years after its introduction, the pill's contraceptive efficacy is proven, its improved safety has been established, and the focus has shifted from supposed health risks to documented and real health benefits.

This article examines some of the issues, including the ''real property'' question, that corporations may encounter in implementing the provisions of Code Section 189 and its regulations. The extension of 189 to regular corporations represents a significant change in congressional intent, since it was originally enacted as a reform measure and is now primarily a provision to raise revenue at a time when Congress is facing a large dificit. Code Section 189 was conceived and enacted in haste, however, and this expansion will undoubtedly have an adverse impact on capital investment at a time when stimulation is needed for themore » economy as a whole. The workload of the courts and the Internal Revenue Service will certainly increase. Careful drafting of the regulations could anticipate potential issues and clarify them in the drafting stage. The meaning of real property, capitalization rate, capitalization period, and self-constructed assets all need to be carefully addressed. 18 references.« less

Applications of Electronic Health Information in Public Health: Uses, Opportunities & Barriers

Tomines, Alan; Readhead, Heather; Readhead, Adam; Teutsch, Steven

2013-01-01

Electronic health information systems can reshape the practice of public health including public health surveillance, disease and injury investigation and control, decision making, quality assurance, and policy development. While these opportunities are potentially transformative, and the federal program for the Meaningful Use (MU) of electronic health records (EHRs) has included important public health components, significant barriers remain. Unlike incentives in the clinical care system, scant funding is available to public health departments to develop the necessary information infrastructure and workforce capacity to capitalize on EHRs, personal health records, or Big Data. Current EHR systems are primarily built to serve clinical systems and practice rather than being structured for public health use. In addition, there are policy issues concerning how broadly the data can be used by public health officials. As these issues are resolved and workable solutions emerge, they should yield a more efficient and effective public health system. PMID:25848571

2016-06-01

Men, transgender people, and those working in off-street locales have historically been underrepresented in sex work health research. Failure to include all sections of sex worker populations precludes comprehensive understandings about a range of population health issues, including potential variations in the manifestation of such issues within and between population subgroups, which in turn can impede the development of effective services and interventions. In this article, we describe our attempts to define, determine, and recruit a purposeful sample for a qualitative study examining the interrelationships between sex workers' health and the working conditions in the Vancouver off-street sex industry. Detailed is our application of ethnographic mapping approaches to generate information about population diversity and work settings within distinct geographical boundaries. Bearing in mind the challenges and the overwhelming discrimination sex workers experience, we scope recommendations for safe and effective purposeful sampling inclusive of sex workers' heterogeneity. © The Author(s) 2015.

'They don't just come for Machu Picchu': locals' views of tourist-local sexual relationships in Cuzco, Peru.

PubMed

Bauer, Irmgard

2008-08-01

Sexual and romantic relationships between local people and tourists have long taken place. Such encounters are not a modern phenomenon, but the potential of sexually transmitted infections (STIs), including HIV/AIDS, warrants greater research into the issue. This paper analyses local people's views of local-tourist relationships in Cuzco/Peru. Data were obtained through in-depth interviews, participant and non-participant observation and informal discussions. Attraction based on physical difference was reportedly the main trigger for such relationships. Emerging themes discussed include issues of self-esteem, strategies of approach, tourists' motives, emotional involvement and expectations from such encounters. Levels of unprotected sexual behaviour and lack of STI awareness are of sufficient concern to recommend urgent action. Suggestions for sexual health education are made with particular emphasis on targeting local people involved in the tourism and hospitality industries.

Chimeric animals are made up of cells from two separate zygotes. Human/non-human animal chimeras have been used for a number of research purposes, including human disease modeling. Pluripotent stem cell (PSC) research has relied upon the chimera approach to examine the developmental potential of stem cells, to determine the efficacy of cell replacement therapies, and to establish a means of producing human organs. Based on ethical issues, this work has faced pushback from various sources including funding agencies. We discuss here the essential role these studies have played, from gaining a better understanding of human biology to providing a stepping stone to human disease treatments. We also consider the major ethical issues, as well as the current status of support for this work in the United States. Copyright © 2017 The Authors. Published by Elsevier B.V. All rights reserved.

2003-01-01

Little research exists on the relationship between working overtime and possible adverse health and safety outcomes for construction workers. Five focus-group discussions were conducted with construction workers from around the United States. From the analyzed transcripts, a model of overtime was developed. The model includes three dominant themes: (1) work organization issues [(a) definitions of overtime, (b) scheduling, and (c) economic conditions], (2) why workers choose to work overtime [(a) management expectations, (b) career, and (c) money], and (3) the effects of working overtime [(a) health and safety, including sleep deprivation, injury, fatigue, and stress, and (b) productivity]. Health and safety is only one of the adverse outcomes related to working too much overtime. A list of worker-inspired recommendations for addressing overtime issues is provided. Both employers and workers need to better understand the potential adverse effects of working too much overtime.

EPA guidance on improving the image of psychiatry.

Möller-Leimkühler, A M; Möller, H-J; Maier, W; Gaebel, W; Falkai, P

2016-03-01

This paper explores causes, explanations and consequences of the negative image of psychiatry and develops recommendations for improvement. It is primarily based on a WPA guidance paper on how to combat the stigmatization of psychiatry and psychiatrists and a Medline search on related publications since 2010. Furthermore, focussing on potential causes and explanations, the authors performed a selective literature search regarding additional image-related issues such as mental health literacy and diagnostic and treatment issues. Underestimation of psychiatry results from both unjustified prejudices of the general public, mass media and healthcare professionals and psychiatry's own unfavourable coping with external and internal concerns. Issues related to unjustified devaluation of psychiatry include overestimation of coercion, associative stigma, lack of public knowledge, need to simplify complex mental issues, problem of the continuum between normality and psychopathology, competition with medical and non-medical disciplines and psychopharmacological treatment. Issues related to psychiatry's own contribution to being underestimated include lack of a clear professional identity, lack of biomarkers supporting clinical diagnoses, limited consensus about best treatment options, lack of collaboration with other medical disciplines and low recruitment rates among medical students. Recommendations are proposed for creating and representing a positive self-concept with different components. The negative image of psychiatry is not only due to unfavourable communication with the media, but is basically a problem of self-conceptualization. Much can be improved. However, psychiatry will remain a profession with an exceptional position among the medical disciplines, which should be seen as its specific strength.

Innovative method for prioritizing emerging disinfection by-products (DBPs) in drinking water on the basis of their potential impact on public health.

Providing microbiologically safe drinking water is a major public health issue. However, chemical disinfection can produce unintended health hazards involving disinfection by-products (DBPs). In an attempt to clarify the potential public health concerns associated with emerging disinfection by-products (EDBPs), this study was intended to help to identify those suspected of posing potential related health effects. In view of the ever-growing list of EDBPs in drinking water and the lack of consensus about them, we have developed an innovative prioritization method that would allow us to address this issue. We first set up an exhaustive database including all the current published data relating to EDBPs in drinking water (toxicity, occurrence, epidemiology and international or local guidelines/regulations). We then developed a ranking method intended to prioritize the EDBPs. This method, which was based on a calculation matrix with different coefficients, was applied to the data regarding their potential contribution to the health risk assessment process. This procedure allowed us to identify and rank three different groups of EDBPs: Group I, consisting of the most critical EDBPs with regard to their potential health effects, has moderate occurrence but the highest toxicity. Group II has moderate to elevated occurrence and is associated with relevant toxicity, and Group III has very low occurrence and unknown or little toxicity. The EDBPs identified as posing the greatest potential risk using this method were as follows: NDMA and other nitrosamines, MX and other halofuranones, chlorate, formaldehyde and acetaldehyde, 2,4,6-trichlorophenol and pentachlorophenol, hydrazine, and two unregulated halomethanes, dichloromethane and tetrachloromethane. Our approach allowed us to define the EDBPs that it is most important to monitor in order to assess population exposure and related public health issues, and thus to improve drinking water treatment and distribution. It is also important to extend our knowledge about exposure to mixtures of emerging DBPs and possible related health effects.

The feasibility of using mobile health applications to conduct observational clinical studies requires rigorous validation. Here, we report initial findings from the Asthma Mobile Health Study, a research study, including recruitment, consent, and enrollment, conducted entirely remotely by smartphone. We achieved secure bidirectional data flow between investigators and 7,593 participants from across the United States, including many with severe asthma. Our platform enabled prospective collection of longitudinal, multidimensional data (e.g., surveys, devices, geolocation, and air quality) in a subset of users over the 6-month study period. Consistent trending and correlation of interrelated variables support the quality of data obtained via this method. We detected increased reporting of asthma symptoms in regions affected by heat, pollen, and wildfires. Potential challenges with this technology include selection bias, low retention rates, reporting bias, and data security. These issues require attention to realize the full potential of mobile platforms in research and patient care.

To explore a number of issues related to boundary violations in psychiatry, including the relationship between the individual physician and his or her patient and broader issues related to various dilemmas arising in academic departments of psychiatry. Several potentially troublesome scenarios are presented and discussed in the contexts of 1) the doctor-patient relationship, 2) sexual boundary violations, and 3) nonsexual forms of exploitation, such as finances, confidentiality, dual relationships, and relationships with industry. A number of examples of boundary problems involving psychiatrists have been explored, and although some of these behaviours are clearly forbidden and harmful, others are less clear and require careful consideration if the profession is to arrive at a thoughtful consensus.

What is learned from longitudinal studies of advertising and youth drinking and smoking? A critical assessment.

PubMed

Nelson, Jon P

2010-03-01

This paper assesses the methodology employed in longitudinal studies of advertising and youth drinking and smoking behaviors. These studies often are given a causal interpretation in the psychology and public health literatures. Four issues are examined from the perspective of econometrics. First, specification and validation of empirical models. Second, empirical issues associated with measures of advertising receptivity and exposure. Third, potential endogeneity of receptivity and exposure variables. Fourth, sample selection bias in baseline and follow-up surveys. Longitudinal studies reviewed include 20 studies of youth drinking and 26 studies of youth smoking. Substantial shortcomings are found in the studies, which preclude a causal interpretation.

Genetic mouse models relevant to schizophrenia complement, and have to a large extent supplanted, pharmacological and lesion-based rat models. The main attraction is that they potentially have greater construct validity; however, they share the fundamental limitations of all animal models of psychiatric disorder, and must also be viewed in the context of the uncertain and complex genetic architecture of psychosis. Some of the key issues, including the choice of gene to target, the manner of its manipulation, gene-gene and gene-environment interactions, and phenotypic characterization, are briefly considered in this commentary, illustrated by the relevant papers reported in this special issue.

What is Learned from Longitudinal Studies of Advertising and Youth Drinking and Smoking? A Critical Assessment

PubMed Central

Nelson, Jon P

2010-01-01

This paper assesses the methodology employed in longitudinal studies of advertising and youth drinking and smoking behaviors. These studies often are given a causal interpretation in the psychology and public health literatures. Four issues are examined from the perspective of econometrics. First, specification and validation of empirical models. Second, empirical issues associated with measures of advertising receptivity and exposure. Third, potential endogeneity of receptivity and exposure variables. Fourth, sample selection bias in baseline and follow-up surveys. Longitudinal studies reviewed include 20 studies of youth drinking and 26 studies of youth smoking. Substantial shortcomings are found in the studies, which preclude a causal interpretation.

Van Dusen, Virgil

2011-01-01

The potential for legal liability involving faculty members and students in higher education settings is a topic that warrants serious attention by administrators. Specific areas identified as high risk include dismissal of a faculty member, denial of tenure, misappropriation of grant-funding, intellectual property conflicts, Family and Medical Leave Act (FMLA) issues, sexual harassment, student suspension, disabilities, and student privacy issues. Examples of litigation in the higher-education setting are presented, along with a list of online resources for additional information. It is important for higher education administrators, faculty members, staff members, and students to recognize the currently accepted legal rights and responsibilities associated with these high-risk areas.

Intimate partner violence (IPV) often culminates in acute physical injury, sexual assault, and mental health issues. It is crucial to understand the healthcare habits of victims to develop interventions that can drastically improve a victim's quality of life and prevent future abuse. The objective of this study is to mine de-identified and aggregated Electronic Health Record data to identify women's health issues that are potentially associated with IPV. In this study we compared health issues of female domestic abuse victims to female non-domestic abuse victims. The Domestic abuse population contained 5870 patients, while the Non-Domestic Abuse population contained 14,315,140 patients. Explorys provides National Big Data from the entire USA. Statistical analysis identified 2429 terms as significantly more prevalent among victims of domestic abuse, compared to the general population. These terms were classified into broad categories, including acute injury, chronic conditions, substance abuse, mental health, disorders, gynecological and pregnancy related problems.

1981-01-01

The use of a training simulator along with carefully structured, detailed, line trip scenarios was envisioned by NASA as a means of providing a controllable, repeatable way to observe line crews in a highly realistic simulation of their working environment and obtain better understanding operationally significant human factors problems and issues. Relevant research done by the agency and the results of full-mission simulation scenarios revealed potential implications for flight training. Aspects to be considered in creating training programs closely related to the actual line environment with a total crew application in real world incident experiences include: (1) operational, environmental, equipment, and crew problems in scenario design; (2) real time line oriented flight training operation; (3) performance assessment and debriefing; (4) instructor qualification and training; and (5) other issues such as ub un initial, transition, and upgrade training; procedures developent and evaluation, and equipment evaluation.

Do Supplemental Remedial Reading Programs Address the Motivational Issues of Struggling Readers? An Analysis of Five Popular Programs.

PubMed

Quirk, Matthew P; Schwanenflugel, Paula J

2004-04-01

Five popular, but distinctly different, remedial reading programs were reviewed regarding the potential to motivate children to read. It is argued that current remedial reading program designs and research on program effectiveness ignore the impact that motivation has on struggling readers. In addition, we develop a theory of reading motivation specific to struggling readers that highlights motivational constructs we feel are important to the improvement of reading skill for this population of students. The three aspects of reading motivation most relevant to the instruction of remedial readers include: (a) improving reading self-efficacy; (b) making internal and controllable outcome attributions for successes and failures associated with reading; and (c) establishing personally relevant value in becoming a better reader. We conclude that, while most programs address some motivational issues and other issues not at all, most programs could make minor modifications that would greatly enhance their motivational impact.

Transplantation and the primary care physician.

PubMed

McGill, Rita L; Ko, Tina Y

2011-11-01

Increasing appreciation of the survival benefits of kidney transplantation, compared with chronic dialysis, has resulted in more patients with kidney disease being referred and receiving organs. The evolving disparity between a rapidly increasing pool of candidates and a smaller pool of available donors has created new issues for the physicians who care for kidney patients and their potential living donors. This article outlines current efforts to address the growing number of patients who await transplantation, including relaxation of traditional donation criteria, maximization of living donation, and donation schemas that permit incompatible donor-recipient pairs to participate through paired donation and transplantation chains. New ethical issues faced by donors and recipients are discussed. Surgical advances that reduce the morbidity of donors are also described, as is the role of the primary physician in medical issues of both donors and recipients.

Coalition Priorité Cancer and the Pharmaceutical Industry in Quebec: Conflicts of Interest in the Reimbursement of Expensive Cancer Drugs?

PubMed Central

Hughes, David; Williams-Jones, Bryn

2013-01-01

In the context of scarce public resources, patient interest groups have increasingly turned to private organizations for financing, including the pharmaceutical industry. This practice puts advocacy groups in a situation of potential conflicts between the interests of patients and those of the drug companies. The interests of patients and industry can converge on issues related to the approval and reimbursement of medications. But even on this issue, interests do not always align perfectly. Using the Quebec example of Coalition Priorité Cancer (CPC) as a case study, we examine the ethical issues raised by such financial relationships in the context of drug reimbursement decision-making. We collected, compiled and analyzed publicly available information on the CPC's organization and activities; this approach allowed us to raise and discuss important questions regarding the possible influence exerted on patient groups by donors. We conclude with some recommendations. PMID:23968674

Rogers, William H.; Waldron, Timothy P.; Stroiney, Steven R.

2011-01-01

The goal of this work was to analytically identify and quantify the issues, challenges, technical hurdles, and pilot-vehicle interface issues associated with conflict detection and resolution (CD&R)in emerging operational concepts for a NextGen terminal aneuvering area, including surface operations. To this end, the work entailed analytical and trade studies focused on modeling the achievable safety benefits of different CD&R strategies and concepts in the current and future airport environment. In addition, crew-vehicle interface and pilot performance enhancements and potential issues were analyzed based on review of envisioned NextGen operations, expected equipage advances, and human factors expertise. The results of perturbation analysis, which quantify the high-level performance impact of changes to key parameters such as median response time and surveillance position error, show that the analytical model developed could be useful in making technology investment decisions.

Urban sprawl and you: how sprawl adversely affects worker health.

PubMed

Pohanka, Mary; Fitzgerald, Sheila

2004-06-01

Urban sprawl, once thought of as just an environmental issue, is currently gaining momentum as an emerging public health issue worthy of research and political attention. Characteristics seen in sprawling communities include increasing traffic volumes; inadequate public transportation; pedestrian unfriendly streets; and the division of businesses, shops, and homes. These characteristics can affect health in many ways. Greater air pollution contributes to higher asthma and other lung disorder rates. An increased dependence on the automobile encourages a more sedentary lifestyle and can potentially contribute to obesity. The increased danger and stress of long commutes can lead to more accidents, anxiety, and social isolation. Occupational health nurses can become involved by promoting physical activity in the workplace, creating programs for injury prevention and stress management, becoming involved in political smart growth measures, and educating and encouraging colleagues to become active in addressing this issue.

Facilitating reintegration for military service personnel, veterans, and their families: An introduction to the special issue.

PubMed

Elnitsky, Christine A; Kilmer, Ryan P

2017-01-01

As service members return from active duty and, in some cases, exit the military, they face a process of reintegration (also referred to as community reintegration) as they seek to resume participation in their life roles as civilians. Facilitating this dynamic process of reintegration for service members, veterans, and their families-including outlining potential strategies for supporting this return to civilian life and its demands, roles, and responsibilities-is the focus of this Special Issue. Reintegration has been framed as a national priority (U.S. Department of Veterans Affairs, 2015) and has been a point of emphasis of efforts at federal, state, and local levels. As the articles in this issue suggest, multiple public, private, and voluntary systems and the communities to which service members, veterans, and their families return can help influence their health outcomes and, ultimately, their reintegration.

Cultural differences in end-of-life care.

Vincent, J L

2001-02-01

The exact time of death for many intensive care unit patients is increasingly preceded by an end-of-life decision. Such decisions are fraught with ethical, religious, moral, cultural, and legal difficulties. Key questions surrounding this issue include the difference between withholding and withdrawing, when to withhold/withdraw, who should be involved in the decision-making process, what are the relevant legal precedents, etc. Cultural variations in attitude to such issues are perhaps expected between continents, but key differences also exist on a more local basis, for example, among the countries of Europe. Physicians need to be aware of the potential cultural differences in the attitudes not only of their colleagues, but also of their patients and families. Open discussion of these issues and some change in our attitude toward life and death are needed to enable such patients to have a pain-free, dignified death.

Managing psychotropic drug costs: will formularies work?

Huskamp, Haiden A

2003-01-01

Payers of pharmaceutical benefits are increasingly turning to drug formularies in an attempt to control rising pharmacy costs, including those for psychotropic drugs. In this paper I examine several issues that policymakers should consider when addressing formulary design for psychotropic drugs: heterogeneity within mental health disorders and limited information about treatment effectiveness for individual patients; the potential for plans to try to use formularies to avoid adverse selection and implications for psychotropic coverage; the interaction of Medicaid formulary policy and manufacturers' incentives for psychotropic innovation; and incentives created by mental health institutions that decrease formularies' potential effectiveness in controlling psychotropic drug costs.

1978-01-01

The potential military role, both offensive and defensive, of a Satellite Power System (SPS) is examined. A number of potential military support possibilities are described. An SPS with military capabilities may have a strong negative impact on international relations if it is not internationalized. The SPS satellite would be vulnerable to military action of an enemy with good space capability, but would experience little or no threat from saboteurs or terrorists, except via the ground controls. The paper concludes with an outline of some of the key issues involved, and a number of recommendations for future study, including some areas for long term efforts.

1982-12-01

A study has been made of issues and researchable questions regarding the influence of potential CO/sub 2/-induced climatic change on grazing lands. Generalized scenarios of possible changes in climate in grazing land regions of the world were constructed based on published and ongoing investigations. These studies were of two general types: (i) general circulation climate, and (ii) analyses of historical data for periods which were warmer than average current conditions, based on the assumption that global warming can be expected. A review of scenarios derived from recent research suggests that surface temperature may increase and precipitation may decrease in somemore » important grazing land regions of the world. Research needs related specifically to climate in grazing lands were discussed. In the second workship, scientists discussed individual abiotic, autotrophic, and heterotrophic processes. Potential studies of these processes which were discussed included (i) work in the laboratory and the field, (ii) modelling, and (iii) analysis and synthesis of existing data bases and scientific literature. Both biological and socio-economic issues were discussed. Several overall conclusions were derived including the following: a planned, time-phased, and integrated study would be desirable to obtain the greatest amount of information for the least amount of funding in future investigations; a relatively small interdisciplinary group should be assembled consisting of individuals with backgrounds in such areas as meteorology, plant ecology, animal ecology, range science, economics, sociology, and systems analysis, and should operate over perhaps 10 years and draw upon specific short-term contractual inputs.« less

Body Dysmorphic Disorder: Some Key Issues for DSM-V

Phillips, Katharine A.; Wilhelm, Sabine; Koran, Lorrin M.; Didie, Elizabeth R.; Fallon, Brian A.; Feusner, Jamie; Stein, Dan J.

2014-01-01

Body dysmorphic disorder (BDD), a distressing or impairing preoccupation with an imagined or slight defect in appearance, has been described for more than a century and increasingly studied over the past several decades. This paper provides a focused review of issues pertaining to BDD that are relevant to DSM-V. The review presents a number of options and preliminary recommendations to be considered for DSM-V: 1) Criterion A may benefit from some rewording, without changing its focus or meaning; 2) Potential disadvantages of adding a new criterion to reflect BDD compulsive behaviors seem to outweigh potential advantages, but adding such a criterion remains an option that can be considered; 3) A clinical significance criterion seems necessary for BDD to differentiate it from normal appearance concerns; 4) BDD and eating disorders have some overlapping features and need to be differentiated; some minor changes to DSM-IV’s criterion C are suggested; 5) BDD should not be broadened to include body integrity identity disorder (apotemnophilia) or olfactory reference syndrome; 6) There is no compelling evidence for including diagnostic features or subtypes that are specific to gender-related, age-related, or cultural manifestations of BDD; 7) Adding muscle dysmorphia as a specifier may have clinical utility; and 8) The ICD-10 criteria for hypochondriacal disorder are not suitable for BDD, and there is no empirical evidence that BDD and hypochondriasis are the same disorder. The issue of how BDD’s delusional variant should be classified in DSM-V is briefly discussed and will be addressed more extensively in a separate paper. PMID:20533368

Update to the College of American Pathologists reporting on thyroid carcinomas.

PubMed

Ghossein, Ronald

2009-03-01

The reporting of thyroid carcinomas follows the recommendations of the College of American Pathologists (CAP) protocols and includes papillary carcinoma, follicular carcinoma, anaplastic carcinoma and medullary carcinoma. Despite past and recent efforts, there are a number of controversial issues in the classification and diagnosis of thyroid carcinomas (TC) that, potentially impact on therapy and prognosis of patients with TC. The most updated version of the CAP thyroid cancer protocol incorporates recent changes in histologic classification as well as changes in the staging of thyroid cancers as per the updated American Joint Commission on Cancer staging manual. Among the more contentious issues in the pathology of thyroid carcinoma include the defining criteria for tumor invasiveness. While there are defined criteria for invasion, there is not universal agreement in what constitutes capsular invasion, angioinvasion and extrathyroidal invasion. Irrespective of the discrepant views on invasion, pathologists should report on the presence and extent (focal, widely) of capsular invasion, angioinvasion and extrathyroidal extension. These findings assist clinicians in their assessment of the recurrence risk and potential for metastatic disease. It is beyond the scope of this paper to detail the entire CAP protocol for thyroid carcinomas; rather, this paper addresses some of the more problematic issues confronting pathologists in their assessment and reporting of thyroid carcinomas. The new CAP protocol for reporting of thyroid carcinomas is a step toward improving the clinical value of the histopathologic reporting of TC. Large meticulous clinico-pathologic and molecular studies with long term follow up are still needed in order to increase the impact of microscopic examination on the prognosis and management of TC.

2016-05-21

The British Columbia take-home naloxone (BCTHN) program has been in operation since 2012 and has resulted in the successful reversal of over 581 opioid overdoses. The study aims to explore BCTHN program participant perspectives about the program, barriers to participants contacting emergency services (calling "911") during an overdose, and perspectives of law enforcement officials on naloxone administration by police officers. Two focus groups and four individual interviews were conducted with BCTHN program participants; interviews with two law enforcement officials were also conducted. Qualitative analysis of all transcripts was performed. Positive themes about the BCTHN program from participants included easy to understand training, correcting misperceptions in the community, and positive interactions with emergency services. Potential barriers to contacting emergency services during an overdose include concerns about being arrested for outstanding warrants or for other illegal activities (such as drug possession) and confiscation of kits. Law enforcement officials noted that warrants were complex situational issues, kits would normally not be confiscated, and admitted arrests for drug possession or other activities may not serve the public good in an overdose situation. Law enforcement officials were concerned about legal liability and jurisdictional/authorization issues if naloxone administration privileges were expanded to police. Program participants and law enforcement officials expressed differing perspectives about warrants, kit confiscation, and arrests. Facilitating communication between BCTHN program participants and other stakeholders may address some of the confusion and remove potential barriers to further improving program outcomes. Naloxone administration by law enforcement would require policies to address jurisdiction/authorization and liability issues.

Young men's health promotion and new information communication technologies: illuminating the issues and research agendas.

PubMed

Robinson, Mark; Robertson, Steve

2010-09-01

The article examines the use of newer, interactive information and communication technologies (ICTs) in young men's health promotion (HP), drawing on gender theory, HP research and evidence on young men's Internet usage. The focus is on highlighting an agenda for research in terms of emerging issues. New forms of social media ICT (for example 'web 2'-based on-line social networking sites, micro-blogging services, i-phones and podcasts) have the potential to enable young men to engage with health information in new and interesting ways. Given concerns about young men's engagement with health services, innovative ICT formats, particularly using the Internet, have been tried. However, issues persist around surfing 'addiction', quality control and equal access. Approaches to HP using new ICTs offer distributed control over information content and quality and a lay social context for accessing information. Online communities can potentially legitimize young men's participation in discourses around health, and support sustained engagement. The article discusses how this could support young men to re-conceptualize healthy choices in the context of masculine imperatives and responsible citizenship if specific conditions are met (for trusting engagement) and risks addressed (such as commercial disinformation). The skill requirements for young men to engage effectively with new ICTs are explored, focusing on health literacy (HL). It is predicted that social marketing approaches to HP for young men will increasingly include new ICTs, making specific requirements for HL. These approaches may appeal narrowly to hegemonic masculinities or broadly to multiple masculinities, including those historically marginalized. Recommendations are made for future research.

Postmortem interrogations of cardiac implantable electronic devices (CIEDs), recommended at autopsy in suspected cases of sudden cardiac death, are rarely performed, and data on systematic postmortem CIED analysis in the forensic pathology are missing. The aim of the study was to determine whether nonselective postmortem CIED interrogations and data analysis are useful to the forensic pathologist to determine the cause, mechanism, and time of death and to detect potential CIED-related safety issues. From February 2012 to April 2017, all autopsy subjects in the department of forensic medicine at the University Hospital Charité who had a CIED underwent device removal and interrogation. Over the study period, 5368 autopsies were performed. One hundred fifty subjects had in total 151 CIEDs, including 109 pacemakers, 35 defibrillators, and 7 implantable loop recorders. In 40 cases (26.7%) time of death and in 51 cases (34.0%) cause of death could not be determined by forensic autopsy. Of these, CIED interrogation facilitated the determination of time of death in 70.0% of the cases and clarified the cause of death in 60.8%. Device concerns were identified in 9 cases (6.0%), including 3 hardware, 4 programming, and 2 algorithm issues. One CIED was submitted to the manufacturer for a detailed technical analysis. Our data demonstrate the necessity of systematic postmortem CIED interrogation in forensic medicine to determine the cause and timing of death more accurately. In addition, CIED analysis is an important tool to detect potential CIED-related safety issues. © 2018 American Heart Association, Inc.

Genetic testing for the BRCA1 gene and the need for protection from discrimination: an evolving legislative and social issue.

PubMed

Dressler, L

1998-04-01

Genetic testing for the BRCA1 gene is available commercially and clinically. The information gained from this test impacts not only on the individual tested, but on family members as well. The test can offer an individual and their family the opportunity to gain valuable information about their risks of developing certain forms of inherited breast cancer and other inherited cancers. In addition to its emotional and psychological impact, this information is associated with significant social and economic issues. This includes the potential for denial, loss, or increased rates for health insurance as well as denial and loss of employment based on genetic test information. The risk for such discrimination can lead to fear of seeking testing and can discourage participation in and potential benefit from prevention, screening, and treatment programs. Therefore, misuse of this information carries significant risk for the individual being tested and for their family members. It is imperative that the potential benefits of genetic testing and genetic information be afforded to all without this risk and fear. In addition to protecting all individuals from genetic discrimination, there is a need to protect the confidentiality of genetic information and an individual's right to privacy. This article discusses protection currently available through legislation at the federal and state level, focusing on the experience in North Carolina in developing and passing a genetic antidiscrimination bill. Although progress has been made, troublesome issues still remain.

2014-06-01

Predator-prey interactions are a main issue in ecological theory, including multispecies predator-prey relationships and intraguild predation. This knowledge is mainly based on the study of plants and animals, while its relevance for microorganisms is not well understood. The three key groups of micro-predators include protists, predatory bacteria and bacteriophages. They greatly differ in size, in prey specificity, in hunting strategies and in the resulting population dynamics. Yet, their potential to jointly control bacterial populations and reducing biomass in complex environments such as wastewater treatment plants is vast. Here, we present relevant ecological concepts and recent findings on micropredators, and propose that an integrative approach to predation at the microscale should be developed enabling the exploitation of this potential.

2011-01-01

Reliable and sensitive pathogen detection in clinical and environmental (including food and water) samples is of greatest importance for public health. Standard microbiological methods have several limitations and improved alternatives are needed. Most important requirements for reliable analysis include: (i) specificity; (ii) sensitivity; (iii) multiplexing potential; (iv) robustness; (v) speed; (vi) automation potential; and (vii) low cost. Microarray technology can, through its very nature, fulfill many of these requirements directly and the remaining challenges have been tackled. In this review, we attempt to compare performance characteristics of the microbial diagnostic microarrays developed for the detection and typing of food and water pathogens, and discuss limitations, points still to be addressed and issues specific for the analysis of food, water and environmental samples.

Family tree and ancestry inference: is there a need for a 'generational' consent?

Wallace, Susan E; Gourna, Elli G; Nikolova, Viktoriya; Sheehan, Nuala A

2015-12-09

Genealogical research and ancestry testing are popular recreational activities but little is known about the impact of the use of these services on clients' biological and social families. Ancestry databases are being enriched with self-reported data and data from deoxyribonucleic acid (DNA) analyses, but also are being linked to other direct-to-consumer genetic testing and research databases. As both family history data and DNA can provide information on more than just the individual, we asked whether companies, as a part of the consent process, were informing clients, and through them clients' relatives, of the potential implications of the use and linkage of their personal data. We used content analysis to analyse publically-available consent and informational materials provided to potential clients of ancestry and direct-to-consumer genetic testing companies to determine what consent is required, what risks associated with participation were highlighted, and whether the consent or notification of third parties was suggested or required. We identified four categories of companies providing: 1) services based only on self-reported data, such as personal or family history; 2) services based only on DNA provided by the client; 3) services using both; and 4) services using both that also have a research component. The amount of information provided on the potential issues varied significantly across the categories of companies. 'Traditional' ancestry companies showed the greatest awareness of the implications for family members, while companies only asking for DNA focused solely on the client. While in some cases companies included text recommending clients inform their relatives, showing they recognised the issues, often it was located within lengthy terms and conditions or privacy statements that may not be read by potential clients. We recommend that companies should make it clearer that clients should inform third parties about their plans to participate, that third parties' data will be provided to companies, and that that data will be linked to other databases, thus raising privacy and issues on use of data. We also suggest investigating whether a 'generational consent' should be created that would include more than just the individual in decisions about participating in genetic investigations.

Breath Analysis in Disease Diagnosis: Methodological Considerations and Applications

2014-01-01

Breath analysis is a promising field with great potential for non-invasive diagnosis of a number of disease states. Analysis of the concentrations of volatile organic compounds (VOCs) in breath with an acceptable accuracy are assessed by means of using analytical techniques with high sensitivity, accuracy, precision, low response time, and low detection limit, which are desirable characteristics for the detection of VOCs in human breath. “Breath fingerprinting”, indicative of a specific clinical status, relies on the use of multivariate statistics methods with powerful in-built algorithms. The need for standardisation of sample collection and analysis is the main issue concerning breath analysis, blocking the introduction of breath tests into clinical practice. This review describes recent scientific developments in basic research and clinical applications, namely issues concerning sampling and biochemistry, highlighting the diagnostic potential of breath analysis for disease diagnosis. Several considerations that need to be taken into account in breath analysis are documented here, including the growing need for metabolomics to deal with breath profiles. PMID:24957037

This report summarizes the results of a six month study that addressed specific issues to transfer the Pd-13Cr static strain sensor to a gas turbine engine environment. The application issues that were addressed include: (1) evaluation of a miniature, variable potentiometer for use as the ballast resistor, in conjunction with a conventional strain gage signal conditioning unit; (2) evaluation of a metal sheathed, platinum conductor leadwire assembly for use with the three-wire sensor; and (3) subjecting the sensor to dynamic strain cyclic testing to determine fatigue characteristics. Results indicate a useful static strain gage system at all temperature levels up to 1350 F. The fatigue characteristics also appear to be very promising, indicating a potential use in dynamic strain measurement applications. The procedure, set-up, and data for all tests are presented in this report. This report also discusses the specific strain gage installation technique for the Pd-13Cr gage because of its potential impact on the quality of the output data.

Non-dairy probiotic food products: An emerging group of functional foods.

2018-04-09

The functional food sector has shown tremendous growth in recent years with the application of probiotic bacteria as "food additives". The utilization of probiotic bacteria in food presents many challenges related to their growth, survival, viability, stability and functionality in food processing, storage and consumption as well as changes of sensory characteristics of probiotic foods. Although dairy foods are currently the most common food carrier to deliver probiotics, an increasing number of non-dairy food matrices exhibit potential for delivery of probiotics. This review provides more recent insight into the emergence of non-dairy probiotics products, the interactions between probiotics and different food matrices and the challenges in developing such products. Some of the technical issues are also reviewed and discussed. These issues include the efficacy of probiotic bacteria in non-chilled, low pH or high water activity foods; the potential loss of bacterial viability, additionally unwanted fermentation and changes of the sensory characteristics of food products which may result in poor microbiological quality and low acceptability to consumers.

Objective To analyze patient perspectives on the role of housing in their potentially preventable hospitalization. Methods Individuals admitted with cardiovascular-or diabetes-related diagnoses (n = 90) in a major medical center in Hawai‘i completed an in-person interview eliciting patient perspectives on key factors leading to hospitalization. Using the framework approach, two independent coders identified themes. This study focused on housing-related findings. Results Overall, 23% of participants reported housing as a precipitating factor to their hospitalization, including 12 with no regular place to stay. Four housing-related themes emerged: challenges meeting basic needs, complex chronic care management difficulties, stigma and relationship with provider, and stress and other mental health issues. Discussion Almost 25% of patients identified housing as a key factor to their hospital stay. Patient-reported themes highlight specific mechanisms by which housing challenges may lead to hospitalization. Addressing housing issues could help reduce the number and associated cost burden of preventable hospitalizations. PMID:28529224

Use of thermoplastic materials as encapsulants in photovoltaic (PV) modules presents a potential concern in terms of high temperature creep, which should be evaluated before thermoplastics are qualified for use in the field. Historically, the issue of creep has been avoided by using thermosetting polymers as encapsulants, such as crosslinked ethylene-co-vinyl acetate (EVA). Because they lack crosslinked networks, however, thermoplastics may be subject to phase transitions and visco-elastic flow at the temperatures and mechanical stresses encountered by modules in the field, creating the potential for a number of reliability and safety issues. Thermoplastic materials investigated in this study include PV-grademore » uncured-EVA (without curing agents and therefore not crosslinked); polyvinyl butyral (PVB); thermoplastic polyurethane (TPU); and three polyolefins (PO), which have been proposed for use as PV encapsulation. Two approaches were used to evaluate the performance of these materials as encapsulants: module-level testing and a material-level testing.« less

Systems biology ('omics) technologies are emerging as tools for the comprehensive analysis and monitoring of human health. In order for these tools to be used in military medicine, clinical sampling and biobanking will need to be optimized to be compatible with downstream processing and analysis for each class of molecule measured. This article provides an overview of 'omics technologies, including instrumentation, tools, and methods, and their potential application for warfighter exposure monitoring. We discuss the current state and the potential utility of personalized data from a variety of 'omics sources including genomics, epigenomics, transcriptomics, metabolomics, proteomics, lipidomics, and efforts to combine their use. Issues in the "sample-to-answer" workflow, including collection and biobanking are discussed, as well as national efforts for standardization and clinical interpretation. Establishment of these emerging capabilities, along with accurate xenobiotic monitoring, for the Department of Defense could provide new and effective tools for environmental health monitoring at all duty stations, including deployed locations.

2014-12-01

Environmental and societal issues are often inherently linked, especially in coastal and estuarine environments, and science and social values must often be balanced in ecosystem management and decision-making. A new seminar course has been developed for the Marine Estuarine and Environmental Science (MEES) graduate program, an inter-institutional program within the University System of Maryland, to examine these issues. This 1-credit course, offered for the first time in Spring 2015, takes a complex systems perspective on major environmental and societal challenges to examine these linked issues in a variety of contexts. After a brief introduction to the emerging field of "geoethics," students develop a list of issues to examine throughout the seminar. Example topics could include fracking, offshore wind technology, dam removal, and iron fertilization, among others. A case-study approach is taken, with each class meeting focusing on one issue. For each case study, students are asked to 1) identify relevant scientific principles and major knowledge gaps, 2) predict potential outcomes, 3) identify stakeholders and likely viewpoints, and 4) construct communication plans to disseminate findings to these stakeholders. At the end of the semester, students give a brief presentation of the ethical aspects of their own research topics.

2015-09-01

Improvements in curative therapies and the advent of screening have led to increased numbers of non-small cell lung cancer (NSCLC) survivors. Most survivors have undergone invasive treatment (surgery, radiation therapy, and/or chemotherapy) and carry a higher comorbidity burden than survivors of other cancers. Overall quality of life (QOL) and health-related quality of life (HRQOL) suffer during the treatment phase, with the potential for long-term decline, and both clinical characteristics and treatment impact these measures. Physical and mental components of HRQOL seem to be most at risk for decline. The issues faced by survivors include physical symptoms such as respiratory issues, fatigue, hearing loss, neuropathy, and postsurgical pain; psychological distress leading to depression, financial issues, and poor compliance with recommended guidelines; and fear or risk of recurrence and secondary malignancies. This article summarizes the major issues faced by NSCLC survivors and suggests appropriate management. Future collaborative efforts are needed to further elucidate the complex issues that affect overall QOL and HRQOL in NSCLC survivors and to develop appropriate interventions in this large and diverse survivor population.

Stem cell research remains a tremendously promising yet controversial field of study. It continues to attract considerable public interest and generate discussion and debate. However, while the high profile of this field has endured, the tone and nature of the discourse that drives this profile appears to be changing. In order to get a better sense of how these potential shifts are perceived by individuals directly embedded in the field, we conducted an international internet survey of members of the stem cell research community. Our participants included individuals publishing on both scientific and ethical, legal and social issues topics. We explored the degree to which participants perceived that key policy issues were becoming more or less contentious over time. We queried views regarding the effect of regulatory frameworks on emerging stem cell research technologies and the extent to which participants experience pressure related to clinical translation. We also explored participants' relationships with industry, experience with patents and perceptions regarding the emphasis placed on the potential economic benefits of stem cell research. Our results suggest that while traditional debates such as those surrounding the moral status of the embryo remain, other issues more closely associated with clinical translation and commercialization are perceived as becoming increasingly contentious. This survey provides useful insight into the perspectives of a sample of active researchers working in countries around the world as well as an opportunity to reflect on the likely direction of future stem cell policy debates.

Corrosion considerations for thermochemical biomass liquefaction process systems in biofuel production

2014-11-11

Thermochemical liquifaction processing of biomass to produce bio-derived fuels (e.g. gasoline, jet fuel, diesel, home heating oil, etc.) is of great recent interest as a renewable energy source. Approaches under investigation include direct liquefaction, hydrothermal liquefaction, hydropyrolysis, fast pyrolysis, etc. to produce energy dense liquids that can be utilized as produced or further processed to provide products of higher value. An issue with bio-oils is that they tend to contain significant concentrations of organic compounds, which make the bio-oil acidic and a potential source of corrosion issues in in transport, storage, and use. Efforts devoted to modified/further processing of bio-oilsmore » to make them less corrosive are currently being widely pursued. Another aspect that must also be addressed is potential corrosion issues in the bio-oil liquefaction process equipment itself. Depending on the specific process, bio-oil liquefaction production temperatures can reach up to 400-600 °C, and involve the presence of aggressive sulfur, and halide species from both the biomass used and/or process additives. Detailed knowledge of the corrosion resistance of candidate process equipment alloys in these bio-oil production environments is currently lacking. Lastly, this paper summarizes our recent, ongoing efforts to assess the extent to which corrosion of bio-oil process equipment may be an issue, with the ultimate goal of providing the basis to select the lowest cost alloy grades capable of providing the long-term corrosion resistance needed for future bio-oil production plants.« less

Purpose To develop, conduct, and evaluate a proactive risk assessment (PRA) of the design and implementation of CPOE in an ICU. Methods We developed a PRA method based on issues identified from documented experience with conventional PRA methods and the constraints of an organization about to implement CPOE in an intensive care unit. The PRA method consists of three phases: planning (three months), team (one five-hour meeting), and evaluation (short- and long-term). Results Sixteen unique relevant vulnerabilities were identified as a result of the PRA team’s efforts. Negative consequences resulting from the vulnerabilities included potential patient safety and quality of care issues, non-compliance with regulatory requirements, increases in cognitive burden on CPOE users, and/or worker inconvenience or distress. Actions taken to address the vulnerabilities included redesign of the technology, process (workflow) redesign, user training, and/or ongoing monitoring. Verbal and written evaluation by the team members indicated that the PRA method was useful and that participants were willing to participate in future PRAs. Long-term evaluation was accomplished by monitoring an ongoing “issues list” of CPOE problems identified by or reported to IT staff. Vulnerabilities identified by the team were either resolved prior to CPOE implementation (n = 7) or shortly thereafter (n = 9). No other issues were identified beside those identified by the team. Conclusions Generally positive results from the various evaluations including a long-term evaluation demonstrate the value of developing an efficient PRA method that meets organizational and contextual requirements and constraints.

Dendritic cell (DC) active immunotherapy is potentially efficacious in a broad array of malignant disease settings. However, challenges remain in optimizing DC-based therapy for maximum clinical efficacy within manufacturing processes that permit quality control and scale-up of consistent products. In this review we discuss the critical issues that must be addressed in order to optimize DC-based product design and manufacture, and highlight the DC based platforms currently addressing these issues. Variables in DC-based product design include the type of antigenic payload used, DC maturation steps and activation processes, and functional assays. Issues to consider in development include: (a) minimizing the invasiveness of patient biological material collection; (b) minimizing handling and manipulations of tissue at the clinical site; (c) centralized product manufacturing and standardized processing and capacity for commercial-scale production; (d) rapid product release turnaround time; (e) the ability to manufacture sufficient product from limited starting material; and (f) standardized release criteria for DC phenotype and function. Improvements in the design and manufacture of DC products have resulted in a handful of promising leads currently in clinical development.

Environmental and social determinants of health often co-occur, particularly among socially disadvantaged populations, yet because they are usually studied separately, their joint effects on health are likely underestimated. Building on converging bodies of literature, we delineate a conceptual framework to address these issues. Previous models provided a foundation for study in this area, and generated research pointing to additional important issues. These include a stronger focus on biobehavioral pathways, both positive and adverse health outcomes, and intergenerational effects. To accommodate the expanded set of issues, we put forward the Integrated Socio-Environmental Model of Health and Well-Being (ISEM), which examines how social and environmental factors combine and potentially interact, via multi-factorial pathways, to affect health and well-being over the life span. We then provide applied examples including the study of how food environments affect dietary behavior. The ISEM provides a comprehensive, theoretically informed framework to guide future research on the joint contribution of social and environmental factors to health and well-being across the life span.

Renewable energy technologies offer the promise of non-polluting alternatives to fossil and nuclear-fueled power plants to meet growing demand for electrical energy. Two emerging categories of renewable energy technologies, hydrokinetic and wave energy conversion devices, offer ways to tap the energy of moving water without impoundment (dams) or diversion required by many conventional hydroelectric facilities. These technologies include devices designed for deployment in natural streams, tidal estuaries, ocean currents, and constructed waterways, as well as devices designed to capture the energy of ocean waves. On October 26-28, 2005, 54 representatives from government, non-governmental organizations, and private business met to (1)more » identify the varieties of hydrokinetic energy and wave technology devices, their stages of development, and the projected cost to bring each to market; (2) identify where these technologies can best operate; (3) identify the potential environmental issues associated with these technologies and possible mitigation measures; (4) develop a list of research needs and/or practical solutions to address unresolved environmental issues.

There are many issues in dealing with the problems of the release of toxic chemicals into the environment. Those issues include determining the extent of the contamination, identifying possible receptor populations, and estimating the amount of exposure to those populations. Geographic Information Systems (GIS) are useful tools to address those issues. With a GIS, a professional can plot the location of areas of contamination, populations can be estimated by linking census data with the graphical data in the GIS or addresses of individuals can be plotted, sampling results can be used to create contours of exposure levels, and overlays ofmore » other relevant information (cancer rates) can all be done using a GIS. The spatial features in a GIS can be used with diffusion and other models to estimate spread of contamination from a source. This paper will use a case study method to demonstrate various aspects of using GIS to answer questions of public health relevance from the potential exposures to toxic substances in the environment. The case study will include a discussion of data identification and gathering, spatial analysis, and a full discussion of the possible conclusions that could be reached using the data in the GIS.« less

Ethical Perspectives on RNA Interference Therapeutics

2008-01-01

RNA interference is a mechanism for controlling normal gene expression which has recently begun to be employed as a potential therapeutic agent for a wide range of disorders, including cancer, infectious diseases and metabolic disorders. Clinical trials with RNA interference have begun. However, challenges such as off-target effects, toxicity and safe delivery methods have to be overcome before RNA interference can be considered as a conventional drug. So, if RNA interference is to be used therapeutically, we should perform a risk-benefit analysis. It is ethically relevant to perform a risk-benefit analysis since ethical obligations about not inflicting harm and promoting good are generally accepted. But the ethical issues in RNA interference therapeutics not only include a risk-benefit analysis, but also considerations about respecting the autonomy of the patient and considerations about justice with regard to the inclusion criteria for participation in clinical trials and health care allocation. RNA interference is considered a new and promising therapeutic approach, but the ethical issues of this method have not been greatly discussed, so this article analyses these issues using the bioethical theory of principles of the American bioethicists, Tom L. Beauchamp and James F. Childress. PMID:18612370

Staff perceptions of addressing lifestyle in primary health care: a qualitative evaluation 2 years after the introduction of a lifestyle intervention tool.

Preventive services and health promotion in terms of lifestyle counselling provided through primary health care (PHC) has the potential to reduce morbidity and mortality in the population. Health professionals in general are positive about and willing to develop a health-promoting and/or preventive role. A number of obstacles hindering PHC staff from addressing lifestyle issues have been identified, and one facilitator is the use of modern technology. When a computer-based tool for lifestyle intervention (CLT) was introduced at a number of PHC units in Sweden, this provided an opportunity to study staff perspectives on the subject. The aim of this study was to explore PHC staff's perceptions of handling lifestyle issues, including the consultation situation as well as the perceived usefulness of the CLT. A qualitative study was conducted after the CLT had been in operation for 2 years. Six focus group interviews, one at each participating unit, including a total of 30 staff members with different professions participated. The interviews were designed to capture perceptions of addressing lifestyle issues, and of using the CLT. Interview data were analysed using manifest content analysis. Two main themes emerged from the interviews: a challenging task and confidence in handling lifestyle issues. The first theme covered the categories responsibilities and emotions, and the second theme covered the categories first contact, existing tools, and role of the CLT. Staff at the units showed commitment to health promotion/prevention, and saw that patients, caregivers, managers and politicians all have responsibilities regarding the issue. They expressed confidence in handling lifestyle-related conditions, but to a lesser extent had routines for general screening of lifestyle habits, and found addressing alcohol the most problematic issue. The CLT, intended to facilitate screening, was viewed as a complement, but was not considered an important tool for health promotion/prevention. Additional resources, for example in terms of manpower, may help to build the structures necessary for the health promotion/prevention task. Committed leaders could enhance the engagement among staff. Cooperation in multi-professional teams seems to be important, and methods or tools perceived by staff as compatible have a potential to be successfully implemented. Economic incentives rewarding quantity rather than quality appear to be frustrating to PHC staff.

2017-10-01

Sleep specialists have proposed measures to counteract the negative short- and long-term consequences of sleep debt, and some have suggested the nap as a potential and powerful "public health tool". Here, we address this countermeasure aspect of napping viewed as an action against sleep deprivation rather than an action associated with poor health. We review the physiological functions that have been associated positively with napping in both public health and clinical settings (sleep-related accidents, work and school, and cardiovascular risk) and in laboratory-based studies with potential public health issues (cognitive performance, stress, immune function and pain sensitivity). We also discuss the circumstances in which napping-depending on several factors, including nap duration, frequency, and age-could be a potential public health tool and a countermeasure for sleep loss in terms of reducing accidents and cardiovascular events and improving sleep-restriction-sensitive working performance. However, the impact of napping and the nature of the sleep stage(s) involved still need to be evaluated, especially from the perspective of coping strategies in populations with chronic sleep debt, such as night and shift workers.

The rising popularity of digital applications, such as social networking, media share sites, and blogging, has significantly affected how medical trainees interact with educators, colleagues, and the public. Despite the increased popularity and use of such applications amongst the current generation of trainees, medical educators have little evidence or guidance about preventing misuse and ensuring standards for professional conduct. As trainees become more technologically savvy, it is the responsibility of medical educators to familiarize themselves not only with the advantages of this technology but also with the potential negative effects of its misuse. Professionalism, appropriateness for public consumption, and individual or institutional representation in digital media content are just some of the salient issues that arise when considering the ramifications of trainees' digital behavior in the absence of established policies or education on risk. In this commentary the authors explore the rising use of digital media and its reflection of medical trainees' professionalism. To address possible issues related to professionalism in digital media, the authors hypothesize potential solutions, including exploring faculty familiarity with digital media and policy development, educating students on the potential risks of misuse, and modeling professionalism in this new digital age.

Reducing the potential for processing contaminant formation in cereal products.

Processing contaminants may be defined as substances that are produced in a food when it is cooked or processed, are not present or are present at much lower concentrations in the raw, unprocessed food, and are undesirable either because they have an adverse effect on product quality or because they are potentially harmful. The presence of very low levels of processing contaminants in common foods is becoming an increasingly important issue for the food industry, as developments in analytical techniques and equipment bring foods under closer and closer scrutiny. This review considers the formation of lipid oxidation products, hydrogenation of polyunsaturated fatty acids to prevent lipid oxidation and the associated risk of trans fatty acid formation. The formation of acrylamide in the Maillard reaction is described, as well as the genetic and agronomic approaches being taken to reduce the acrylamide-forming potential of cereal grain. The multiple routes for the formation of furan and associated chemicals, including hydroxymethylfurfuryl, are also described. The evolving regulatory and public perception situations for these processing contaminants and their implications for the cereal supply chain are discussed, emphasising the need for cereal breeders to engage with the contaminants issue.

This overview covers a wide range of cannabis topics, initially examining issues in dispensaries and self-administration, plus regulatory requirements for production of cannabis-based medicines, particularly the Food and Drug Administration “Botanical Guidance.” The remainder pertains to various cannabis controversies that certainly require closer examination if the scientific, consumer, and governmental stakeholders are ever to reach consensus on safety issues, specifically: whether botanical cannabis displays herbal synergy of its components, pharmacokinetics of cannabis and dose titration, whether cannabis medicines produce cyclo-oxygenase inhibition, cannabis-drug interactions, and cytochrome P450 issues, whether cannabis randomized clinical trials are properly blinded, combatting the placebo effect in those trials via new approaches, the drug abuse liability (DAL) of cannabis-based medicines and their regulatory scheduling, their effects on cognitive function and psychiatric sequelae, immunological effects, cannabis and driving safety, youth usage, issues related to cannabis smoking and vaporization, cannabis concentrates and vape-pens, and laboratory analysis for contamination with bacteria and heavy metals. Finally, the issue of pesticide usage on cannabis crops is addressed. New and disturbing data on pesticide residues in legal cannabis products in Washington State are presented with the observation of an 84.6% contamination rate including potentially neurotoxic and carcinogenic agents. With ongoing developments in legalization of cannabis in medical and recreational settings, numerous scientific, safety, and public health issues remain. PMID:27683558

Soliciting scientific information and beliefs in predictive modeling and adaptive management

Glynn, P. D.; Voinov, A. A.; Shapiro, C. D.

2015-12-01

Post-normal science requires public engagement and adaptive corrections in addressing issues with high complexity and uncertainty. An adaptive management framework is presented for the improved management of natural resources and environments through a public participation process. The framework solicits the gathering and transformation and/or modeling of scientific information but also explicitly solicits the expression of participant beliefs. Beliefs and information are compared, explicitly discussed for alignments or misalignments, and ultimately melded back together as a "knowledge" basis for making decisions. An effort is made to recognize the human or participant biases that may affect the information base and the potential decisions. In a separate step, an attempt is made to recognize and predict the potential "winners" and "losers" (perceived or real) of any decision or action. These "winners" and "losers" include present human communities with different spatial, demographic or socio-economic characteristics as well as more dispersed or more diffusely characterized regional or global communities. "Winners" and "losers" may also include future human communities as well as communities of other biotic species. As in any adaptive management framework, assessment of predictions, iterative follow-through and adaptation of policies or actions is essential, and commonly very difficult or impossible to achieve. Recognizing beforehand the limits of adaptive management is essential. More generally, knowledge of the behavioral and economic sciences and of ethics and sociology will be key to a successful implementation of this adaptive management framework. Knowledge of biogeophysical processes will also be essential, but by definition of the issues being addressed, will always be incomplete and highly uncertain. The human dimensions of the issues addressed and the participatory processes used carry their own complexities and uncertainties. Some ideas and principles are provided that may help guide and implement the proposed adaptive management framework and its public and stakeholder engagement processes. Examples and characteristics of issues that could be beneficially addressed through the proposed framework will also be presented.
