Medical students(MS) will face ethical issues throughout their lives as doctors. The present study aims to investigate medical students' opinions on controversial ethical issues and factors associated with these opinions. SBRAME (Spirituality and Brazilian Medical Education) is a multicenter study involving 12 Brazilian medical schools with 5950 MS. Participants completed a questionnaire that collected information on socio-demographic data, medical schools characteristics, religious beliefs and opinions on controversial ethical issues. Of all MS, 3630 participated in the survey (61.0%). The sample was 53.8% women and the mean age was 22.5 years. In general, most MS have no objections to prescription of birth control (90.8%), adult stem cell use (87.5%), embryonic stem cell use (82.0%) and abortion for genetic reasons (51.2%). Approximately half of students have no objections to human cloning (47.3%), 45.7% to withdrawal of artificial life support, 41.4% to euthanasia and 23.3% to abortion for failed contraception. Socio-demographic data such as age, gender and income had little influence on MS opinions. On the other hand, medical schools characteristics (number of medical students in the university, year of medical school foundation, location of the university and type of university) and religious aspects (religious affiliation, religious attendance, non-organizational religiousness and intrinsic religiousness) were highly correlated with their opinions. In general, MS with more supportive opinions on controversial ethical issues were less religious and from non-traditional (newer), urban, public and bigger universities. The current study reveals MS have different opinions regarding controversial ethical issues. Noteworthy, these opinions seem to be shaped more by university characteristics and religious beliefs than socio-demographic data.

Subclinical Cushing's syndrome is a condition of hypercortisolism in the absence of signs specific of overt cortisol excess, and it is associated with an increased risk of diabetes, hypertension, fragility fractures, cardiovascular events and mortality. The subclinical Cushing's syndrome is not rare, being estimated to be between 0.2-2 % in the adult population. Despite the huge number of studies that have been published in the recent years, several issues remain controversial for the subclinical Cushing's syndrome screening, diagnosis and treatment. The Altogether to Beat Cushing's syndrome Group was founded in 2012 for bringing together the leading Italian experts in the hypercortisolism-related diseases. This document represents the Altogether to Beat Cushing's syndrome viewpoint regarding the following controversial issues on Subclinical Cushing's syndrome (SCS): (1) Who has to be screened for subclinical Cushing's syndrome? (2) How to screen the populations at risk? (3) How to diagnose subclinical Cushing's syndrome in patients with an adrenal incidentaloma? (4) Which consequence of subclinical Cushing's syndrome has to be searched for? (5) How to address the therapy of choice in AI patients with subclinical Cushing's syndrome? (6) How to follow-up adrenal incidentaloma patients with subclinical Cushing's syndrome surgically or conservatively treated? Notwithstanding the fact that most studies that faced these points may have several biases (e.g., retrospective design, small sample size, different criteria for the subclinical Cushing's syndrome diagnosis), we believe that the literature evidence is sufficient to affirm that the subclinical Cushing's syndrome condition is not harmless and that the currently available diagnostic tools are reliable for identifying the majority of individuals with subclinical Cushing's syndrome.

Key non-controversial concepts of population education.

PubMed

Sikes, O J; Palacio, J; Kerr, B

1993-03-01

The important components of population education should focus on sexuality rather than sex education; content for inclusion depends upon whether the goal is population awareness or critical awareness. Population awareness is the better understanding of the nature, causes, and consequences of population changes experienced by a community, country, region. Critical awareness is the intent and ability to change the sociocultural or educational characteristics that influence fertility, mortality, and migration. 6 basic concepts with universal applicability are discussed, because if not handled properly, the topic become controversial. The concepts are linked to developing thinking or reasoning ability. The concepts are as follows: 1) respect for others, particularly those of the opposite sex; 2) development of self-esteem for both boys and girls; 3) the knowledge that planning is possible and desirable; 4) postponement of first pregnancy; 5) acceptance of responsibility for the consequences of behavior; and 6) the ability to recognize and withstand social pressure. When children learn respect for others, there is little likelihood that others will be harmed. Respect for girls and women is particularly important, and harmful stereotyping and their effects should be pointed out. The key is to develop healthy attitudes and values toward people, not just an intellectualization of gender issues. Self-esteem is used here to mean self-worth in the present and the future. Children can be helped to develop confidence, perseverance, and optimism. Children need to understand that carefully thought out decisions should precede a birth; fatalism and destiny is a choice. Postponing the first pregnancy can lead to economic, emotional, and physical benefits. Risk to the health of the mother and baby occurs during the teen years. The best time for pregnancy is between the ages of 20 and 30 years. A pregnancy in the teen years may have longterm consequences such as more pregnancy and

Ethical Considerations for Psychologists Taking a Public Stance on Controversial Issues: The Balance Between Personal and Professional Life

PubMed Central

Haeny, Angela M.

2014-01-01

Previous literature has documented the general issues psychologists often face while balancing their personal and professional lives. The struggle stems from attempting to satisfy the need to maintain a life outside of work while having the professional obligation to follow the American Psychological Association’s (APA’s) Ethical Principles of Psychologists and Code of Conduct (Ethics Code) to prevent their personal lives from interfering with their professional roles and relationships. The present paper analyzes the subject of psychologists taking a public position on controversial public issues. Although the APA Ethics Code does not restrict how psychologists conduct themselves during their personal time, taking a public stance on a controversial issue could potentially strain professional relationships and inadvertently reflect negatively on the profession. The present paper examines ethical issues that a) should be taken into account before psychologists take a public position on a controversial issue, and b) are in conflict with APA’s Ethics Code or current research.

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

Scientific risk communication about controversial issues influences public perceptions of scientists' political orientations and credibility

PubMed Central

2018-01-01

Many scientists communicate with the public about risks associated with scientific issues, but such communication may have unintended consequences for how the public views the political orientations and the credibility of the communicating scientist. We explore this possibility using an experiment with a nationally representative sample of Americans in the fall of 2015. We find that risk communication on controversial scientific issues sometimes influences perceptions of the political orientations and credibility of the communicating scientist when the scientist addresses the risks of issues associated with conservative or liberal groups. This relationship is moderated by participant political ideology, with liberals adjusting their perceptions of the scientists' political beliefs more substantially when the scientist addressed the risks of marijuana use when compared with other issues. Conservatives' political perceptions were less impacted by the issue context of the scientific risk communication but indirectly influenced credibility perceptions. Our results support a contextual model of audience interpretation of scientific risk communication. Scientists should be cognizant that audience members may make inferences about the communicating scientist's political orientations and credibility when they engage in risk communication efforts about controversial issues.

2017-01-01

The recently passed legislation and proposed policy changes governing the healthcare system have been met with extensive debate and controversy. The primary objective of the study was to determine the attitudes of Doctor of Physical Therapy (DPT) students towards some of these controversial issues. The secondary objective was to determine the demographic factors, including number of years in a physical therapy program, that contribute to their attitude formation. The research design was a cross-sectional non-experimental survey. Purposive sampling was used to recruit subjects in a public university. Subjects took the survey including nine Likert scale questions/statements on controversial issues inspired from legislative efforts and news media sources and one open-ended question. Of the 111 recruited, 106 students agreed to participate as subjects and completed the survey. Only 18.9% agreed or strongly agreed that the Patient Protection and Affordable Care Act is a positive solution for the healthcare system in America. Political affiliation, class level, and developmental environment were associated with a few questions/statements. DPT students in the sample had very diverse attitudes towards controversial issues in healthcare policy. Some of these attitudes revealed very different paradigms from the results found among medical students and the general public.

Collective judicial management of mass toxic tort controversies: lessons and issues from the Agent Orange litigation.

PubMed

Novey, L B

1988-01-01

Viewing the Agent Orange litigation as a case study, this article explores the feasibility and desirability of strengthening the powers of the courts to manage toxic tort controversies en masse. The Agent Orange lawsuit, brought on behalf of potentially millions of Vietnam War veterans and family members, charged that herbicides used for military purposes during the war caused a wide range of health problems. This article first reviews the current national debate over how mass toxic tort controversies should be handled, including key legislative reform options, and describes how attention is increasingly focused on ways that the court system might better cope with mass toxic torts. The principal events of the Agent Orange litigation are then summarized, by which the litigation was consolidated into a massive class action, the class action was settled, and a streamlined plan for distributing the settlement fund was adopted. The article evaluates the outcome of the litigation, and discusses whether the solution there can and should be broadly applied to other mass toxic tort cases. This question depends, in part, on a series of complex legal and practical issues, but the author suggests that the question will also depend on what institutional role we expect the judiciary to play within society.

Scientific literacy for citizenship: Tools for dealing with the science dimension of controversial socioscientific issues

NASA Astrophysics Data System (ADS)

Kolst, Stein D.

2001-05-01

This article offers a general framework for examining the science dimension of controversial socioscientific issues. Eight specific content-transcending topics to be emphasized in science education are proposed. The topics are grouped under the headings science as a social process, limitations of science, values in science, and critical attitude. Each topic is explored, and it is argued that knowledge of the topics can serve as tools for students' examination of science-related claims in controversial socioscientific issues. The underlying perspective here is empowerment and the needs of students as lay people. The need of society as a whole for decisions to be made on a broad and firm basis is nevertheless also included. The main reason for suggesting the eight content-transcending topics is to provide focal points for the future development of teaching models aimed at science education for citizenship.

Policing Matters: Addressing the Controversial Issue of Policing Through Education for Reconciliation

Cusack, Mella

2009-05-01

Policing is widely held to constitute a contentious issue in classrooms on both sides of the border on the island of Ireland, despite the fact that the ongoing peace process has led to a normalising of cross-border policing relationships. The Education for Reconciliation Project works with teachers and members of the two police services to produce teaching/learning modules on law and policing for use in Citizenship Education classrooms. This paper examines the commonly-held teacher perception of policing as a controversial issue and the reasons why these perceptions exist. It takes into consideration the opinion that it is time for schools to begin work on policing, and investigates the implications for practice.

This study analyzes the issue attention cycle for print and online media coverage of a scientific publication examining the deaths of Chinese factory workers due to lung damage from chronic exposure to nanoparticles. The results of the nanoparticle study, published in 2009, embody news values that would make the study a prime candidate for press coverage, namely, novelty, negativity, controversy, and potential widespread impact. Nevertheless, mentions of the event in traditional English-language print media were nearly nonexistent. Online media, on the other hand, gave the story greater coverage. This case study exemplifies why online media may not be bound to the same issue attention cycle that print media are for controversial scientific events.

Perspective: Challenges and Controversial Issues in the Dietary Guidelines for Americans, 1980-2015.

PubMed

Nestle, Marion

2018-03-01

Since 1980, every edition of the Dietary Guidelines for Americans (DGAs) has recommended increased consumption of fruits, vegetables, and whole grains, but reduced consumption of saturated fat, sugars, and sodium and, therefore, their primary food sources. Every edition has generated controversy, mainly from producers of foods affected by "eat less" recommendations, particularly meat. Objections to the 2015 DGAs focused on environmental as well as scientific issues, but also on purported conflicts of interest among members of the Dietary Guidelines Advisory Committee. On this basis, critics induced Congress to authorize the National Academy of Medicine (NAM) to review the process of drawing up the guidelines. The NAM's 2017 reports should strengthen the process, but as long as science continues to support advice to reduce consumption of targeted foods, the guidelines will continue to elicit political controversy.

Promoting the role of the personal narrative in teaching controversial socio-scientific issues

NASA Astrophysics Data System (ADS)

Levinson, Ralph

2008-09-01

Citizens participating in contemporary socio-scientific issues (SSI) need to draw on local knowledge and personal experience. If curricular developments in the teaching of controversial SSI are to reflect contemporary notions of citizenship then the personal narrative is an indispensable instrument in bridging the gap between the local/personal and the emergent science. In the context of controversy personal narratives help contending parties to see events in the light of those who do not share their views. A goal-oriented protagonist is the narrator in the personal narrative, which consists of three components - situation-event-reaction—the reaction being an evaluation of the event. Promoting personal narratives in science-based curricula is considered problematic given the dominant role of science’s explanatory frameworks. An inter-disciplinary approach is proposed based on McLaughlin’s levels of disagreement.

De Nicola, Luca; Di Lullo, Luca; Paoletti, Ernesto; Cupisti, Adamasco; Bianchi, Stefano

2018-06-07

Chronic hyperkalemia is a major complication of chronic kidney disease (CKD) that occurs frequently, heralds poor prognosis, and necessitates careful management by the nephrologist. Current strategies aimed at prevention and treatment of hyperkalemia are still suboptimal, as evidenced by the relatively high prevalence of hyperkalemia in patients under stable nephrology care, and even in the ideal setting of randomized trials where best treatment and monitoring are mandatory. The aim of this review was to identify and discuss a range of unresolved issues related to the management of chronic hyperkalemia in non-dialysis CKD. The following topics of clinical interest were addressed: diagnosis, relationship with main comorbidities of CKD, therapy with inhibitors of the renin-angiotensin-aldosterone system, efficacy of current dietary and pharmacological treatment, and the potential role of the new generation of potassium binders. Opinion-based answers are provided for each of these controversial issues.

Adequate symptom relief is a central aspect of medical care of all patients especially in those with an incurable disease. However, as an illness progresses and the end of life approaches, physical or psychoexistential symptoms may remain uncontrollable requiring palliative sedation. Although palliative sedation has become an increasingly implemented practice in the care of terminally ill patients, sedation in the management of refractory psychological symptoms and existential distress is still a controversial issue and much debated. This case report presents a patient who received palliative sedation for the treatment of existential distress and discusses considerations that may arise from such a therapeutic approach.

Contrasting Controversies: Fracking and Climate Change

Slickwater high-volume hydraulic fracturing (commonly known as "fracking") is highly controversial. So is global warming, and the two issues are closely related, but the natures of these two controversies have substantial and important differences. Building upon years of experience in teaching and developing resources and strategies for teaching about evolution and climate change, staff at the Paleontological Research Institution have engaged in public outreach and educator professional development to help nurture understanding of fracking and the broader energy system. How are these controversies similar to and different from one another, and how should understanding these similarities and differences inform educational programming (and about how you talk about these issues with your Uncle Fred at the family holiday dinner?). It is nearly universally agreed amongst scientists who study climate that changes now underway are real and human caused, and are posing or likely to pose very serious problems for humanity. Scientists who study slickwater high-volume hydraulic fracturing agree that it causes environmental damage, but there is no consensus as to whether fracking causes more or less harm (e.g., among different kinds of environment harm, across different temporal and spatial scales, and among different social contexts) than other ways of producing energy on a large scale. In other words, the basic tenets of climate change are not a matter of scientific controversy, though the implications for policy making obviously remain politically controversial, while fracking is an issue of both scientific and political controversy. Without advocating for or against fracking, we help audiences disentangle scientific and political issues, better understand the energy resources used in their own communities, and consider issues of scale, systems, and complexity. We will compare and contrast the overlapping controversies surrounding climate change and fracking and highlight

2008-05-01

Donation after cardiac death (DCD) remains controversial in some pediatric institutions. An evidence-based, consensus-building approach to setting institutional policy about DCD can address the controversy openly and identify common ground. To resolve an extended internal debate regarding DCD policy at Children's Hospital Boston, a multidisciplinary task force was commissioned to engage in fact finding and deliberations about clinical and ethical issues in pediatric DCD, and attempt to reach consensus regarding the development of a protocol for pediatric DCD. Issues examined included values and attitudes of staff, families, and the public; number of possible candidates for DCD at the hospital; risks and benefits for child donors and their families; and research needs. Consensus was reached on a set of foundational ethical principles for pediatric DCD. With assistance from the local organ procurement organization (OPO), the task force developed a protocol for pediatric kidney DCD which most members believed could meet all the requirements of the foundational ethical principles. Complete consensus on the use of the protocol was not reached; however, almost all members supported initiation of kidney DCD for older pediatric patients who had wished to be organ donors. The hospital has implemented the protocol on this limited basis and established a process for considering proposals to expand the eligible donor population and include other organs.

Sexual Orientation, Controversy, and Science.

SummaryOngoing political controversies around the world exemplify a long-standing and widespread preoccupation with the acceptability of homosexuality. Nonheterosexual people have seen dramatic surges both in their rights and in positive public opinion in many Western countries. In contrast, in much of Africa, the Middle East, the Caribbean, Oceania, and parts of Asia, homosexual behavior remains illegal and severely punishable, with some countries retaining the death penalty for it. Political controversies about sexual orientation have often overlapped with scientific controversies. That is, participants on both sides of the sociopolitical debates have tended to believe that scientific findings-and scientific truths-about sexual orientation matter a great deal in making political decisions. The most contentious scientific issues have concerned the causes of sexual orientation-that is, why are some people heterosexual, others bisexual, and others homosexual? The actual relevance of these issues to social, political, and ethical decisions is often poorly justified, however. © The Author(s) 2016.

Brokered dialogue: A new research method for controversial health and social issues.

Parsons, Janet A; Lavery, James V

2012-07-02

Dialogue is a foundational feature of social life and an important way in which we come to understand one another. In situations of controversy dialogue is often absent because of a range of social barriers. We have developed a new film-based qualitative research method for studying controversial issues in healthcare and social policy. We call this method Brokered Dialogue. Theoretically informed by the traditions in narrative inquiry and visual anthropology, the method is premised on the idea that dialogue possesses features making it unique as a generator of new knowledge and opportunities for social intervention. Film is not only an extraordinarily rich data source, but an excellent medium for knowledge transfer and dissemination. The paper introduces the Brokered Dialogue method. We outline its critical steps, including the procedures for sampling, data collection and data analysis of both textual and visual data. Participants in a Brokered Dialogue engage in filmed interviews that capture their perspectives on a given topic; they then share their perspectives with, and pose questions of, one another through the medium of film. Using a participatory editing process, only footage that participants feel comfortable showing to others is incorporated. This technique offers participants a 'safe' space for respectful interaction. The editing process itself is analytic, and the final assembly of footage approximates a dialogue on the topic at hand. A link to a film produced from a project piloting the method is provided to demonstrate its real world application. Brokered Dialogue is a method for promoting respectful interactions among those with seemingly divergent views on a controversial topic and for discovering critical points of divergence that may represent pathways for improvement. While the end product is a 'film', the goal is to have these films used as catalysts for ongoing respectful dialogue and problem-solving concerning the topic at hand informing

Controversies in rabies vaccination.

Ghosh, Tapan Kr

2003-06-01

Rabies is a cent per cent fatal disease and there should not be any controversy in giving rabies vaccine to the victims. WHO has fixed schedules for doses for both pre and post-exposure in different category of cases, which also help us to avoid all controversies. But controversies arise in five main areas, which are related to the strategies of rabies prevention. These are: (i) Replacing use of NTV by MTCV. (ii) Intradermal schedule of MTCV, in place of Essen protocol of 5 i.m. doses to reduce the cost. (iii) Acceptability and inclusion of pre-exposure doses of MTCV in the immunization schedule of children as additional vaccine (iv) Schedule for re-exposure in already post-exposure vaccinated cases and schedule for exposure in pre-exposure vaccinated cases. (v) Uses of RIG in WHO category III cases. If these controversial issues are considered scientifically, rabies prophylaxis will see the light of success.

A Cross-Continental Study on Children's Drawings of Football Players: Implications for Understanding Key Issues and Controversies in Human Figure Drawings

Baluch, Bahman; Duffy, Linda J.; Badami, Rokhsareh; Pereira, Elisangela C. Ap

2017-01-01

Professionals examine various aspects of girls’ and boys’ drawings as a way of understanding their intelligence, personality and emotional state. However, the extent to which such measures could be universally generalised or attributed to a specific cultural norm is still a debatable issue. In the present study five key features of children’s drawings namely: the size (height) of the drawings, profile or full face, figure in action or static, shaded or non-shaded and the nature of additional details were examined from a cross-cultural perspective, and by providing a topic (football) for which children’s drawing of a human figure could provide opportunities for the latter indices to manifest and flourish. Children from three countries; England, Iran and Brazil, representing three continents took part in this study. The participants were asked to draw a football player from their own country and from the other participating countries. The results showed that Brazilian children differ from Iranian and English children by drawing significantly smaller figures and putting more football action in the drawings. Shading of the figure drawn was more prevalent amongst English children. Such findings have implications for the interpretation of key aspects of children's drawings in educational, clinical and therapeutic settings and from a universal vs. culturally-specific viewpoint.

2015-10-01

In response to a joint request from the World Climate Research Program's Climate and Cryosphere Project, the International Arctic Science Committee, and the Arctic Council's Arctic Monitoring and Assessment Program an updated scientific assessment has been conducted of the Arctic Freshwater System (AFS), entitled the Arctic Freshwater Synthesis (AFSΣ). The major reason behind the joint request was an increasing concern that changes to the AFS have produced, and could produce even greater, changes to biogeophysical and socioeconomic systems of special importance to northern residents and also produce extra-Arctic climatic effects that will have global consequences. The AFSΣ was structured around six key thematic areas: atmosphere, oceans, terrestrial hydrology, terrestrial ecology, resources, and modeling, the review of each coauthored by an international group of scientists and published as separate manuscripts in this special issue of Journal of Geophysical Research-Biogeosciences. This AFSΣ summary manuscript reviews key issues that emerged during the conduct of the synthesis, especially those that are cross-thematic in nature, and identifies future research required to address such issues.

2016-01-01

Although endometrial cancer (EC) is the most common gynecologic cancer in developed countries, several aspects of its management are still controversial. In particular, the need to perform lymphadenectomy represents an important matter of discussion. Because of the discordant results in the literature, it is still not possible to draft any definitive conclusions regarding the therapeutic value of lymph node dissection. The present review discusses the role of lymphadenectomy in the setting of EC, risk factors for lymphatic spread, identification of patients at risk for lymph node dissemination, and the current evidence for adjuvant therapies in patients with positive nodes. Reasons for the difficulty in demonstrating any therapeutic value of pelvic and para-aortic lymphadenectomy are also discussed.

Butt, Muhammad U; Zacharias, Nikolaos; Velmahos, George C

2009-01-01

Penetrating abdominal injuries have been traditionally managed by routine laparotomy. New understanding of trajectories, potential for organ injury, and correlation with advanced radiographic imaging has allowed a shift towards non-operative management of appropriate cases. Although a selective approach has been established for stab wounds, the management of abdominal gunshot wounds remains a matter of controversy. In this chapter we describe the rationale and methodology of selecting patients for non-operative management. We also discuss additional controversial issues, as related to antibiotic prophylaxis, management of asymptomatic thoracoabdominal injuries, and the use of colostomy vs. primary repair for colon injuries.

2012-01-01

Research into the pathogenesis of dengue fever has exploded over the last half-century, with issues that were considered simple becoming more complex as additional data are found. This has led to the development of a number of controversies that are being studied across the globe and debated in the literature. In this paper, the following six controversies are analysed and, where possible, resolved: the 1997 World Health Organization (WHO) case definition of dengue haemorrhagic fever (DHF) is not useful; DHF is not significantly associated with secondary dengue infection; DHF results from infection with a ‘virulent’ dengue virus; DHF is owing to abnormal T-cell responses; DHF results from auto-immune responses; and DHF results from direct infection of endothelial cells.

In both atypical hemolytic uremic syndrome (aHUS) and C3 glomerulopathy (C3G) complement plays a primary role in disease pathogenesis. Herein we report the outcome of a 2015 Kidney Disease: Improving Global Outcomes (KDIGO) Controversies Conference where key issues in the management of these 2 diseases were considered by a global panel of experts. Areas addressed included renal pathology, clinical phenotype and assessment, genetic drivers of disease, acquired drivers of disease, and treatment strategies. In order to help guide clinicians who are caring for such patients, recommendations for best treatment strategies were discussed at length, providing the evidence base underpinning current treatment options. Knowledge gaps were identified and a prioritized research agenda was proposed to resolve outstanding controversial issues. Copyright © 2016 International Society of Nephrology.

Lyme disease: diagnostic issues and controversies.

PubMed

Aguero-Rosenfeld, Maria E; Wormser, Gary P

2015-01-01

The diagnosis of Lyme disease is a controversial topic. Most practitioners and scientists recognize that Lyme disease is associated with certain objective clinical manifestations supported by laboratory evidence of infection with Borrelia burgdorferi sensu lato (the etiologic agent). There are others, however, who believe that patients with Lyme disease may have a wide variety of entirely nonspecific symptoms without any objective clinical manifestation and that laboratory evidence of infection by B. burgdorferi is not required to support the diagnosis. In reality, this perspective is not evidence based and would inevitably lead to innumerable misdiagnoses, given the high frequency of medically unexplained symptoms, such as fatigue and musculoskeletal pains, in the general population. Although those espousing this viewpoint do not believe that a positive laboratory test is required, nevertheless, they often seek out and promote alternative, unapproved testing methods that frequently provide false-positive results to justify their diagnosis. Herein, we provide a brief overview of Lyme disease testing, emphasizing current usage and limitations. We also discuss the use of nonvalidated procedures and the prospects for a reduction in such testing practices in the future.

Controversial issues: female genital mutilation.

PubMed

Richards, D

2000-01-01

As immigrant women from African countries enter the U.S., Canada, Australia, and Western Europe, western health care providers are beginning to see patients affected by the cultural practice of Female Genital Mutilation (FGM). Unfamiliar with the practice, either medically or culturally, these providers are turning to medical librarians for information. Complicating the issue are the strong negative feelings most western health care workers have about FGM, which appears to them to be both barbaric and cruel. These feelings may conflict strongly with those of their immigrant patients, who regard the practice as normal and desirable. Both medical and cultural information are needed for the professional to provide treatment of medical conditions, while also establishing a good relationship with the FGM affected patient. This article identifies and describes the most important refereed journal article databases, available now over the Internet, providing both medical and cultural information on FGM, and the most useful Web sites for health professionals, librarians, and interested laypersons who need information about this difficult multicultural issue.

Physical activity and sedentary behaviours in youth: issues and controversies.

PubMed

Biddle, Stuart J; Gorely, Trish; Marshall, Simon J; Murdey, Ian; Cameron, Noel

2004-01-01

There is growing concern over the effects of sedentary lifestyles on the health of young people. Recent rapid increases in juvenile obesity have received a great deal of attention in the scientific and popular press and have been attributed partly to television viewing, computer games and other sedentary behaviours. These are thought to compete with physical activity. There is a 'moral panic' concerning the 'couch kids' culture in modern western society. Project STIL (Sedentary Teenagers and Inactive Lifestyles) at Loughborough University is investigating 'what young people do' and focuses on active and inactive pursuits chosen in their leisure time. The following issues are addressed in this paper with specific reference to young people: how do we define 'sedentary behaviour' and do key sedentary behaviours displace physical activity? Are key sedentary behaviours obesogenic? What are the secular trends for children and youth for TV viewing? Our results for young people suggest that: 1. TV viewing and video-game playing are largely uncorrelated with physical activity, suggesting that there is time for both 2. meta-analytic findings show that body fatness is not related in any clinically meaningful way with key sedentary behaviours 3. although more children and youth have greater access to TVs than in previous generations, the amount of TV watched per head has not changed for 40 years. Preliminary findings from Project STIL suggest that inactivity is more complex that we sometimes think. Indeed, measures of 'couch potato-ism', such as TV viewing, may be inappropriate markers of inactivity.

Three controversies over item disclosure in medical licensure examinations

Park, Yoon Soo; Yang, Eunbae B.

2015-01-01

In response to views on public's right to know, there is growing attention to item disclosure – release of items, answer keys, and performance data to the public – in medical licensure examinations and their potential impact on the test's ability to measure competence and select qualified candidates. Recent debates on this issue have sparked legislative action internationally, including South Korea, with prior discussions among North American countries dating over three decades. The purpose of this study is to identify and analyze three issues associated with item disclosure in medical licensure examinations – 1) fairness and validity, 2) impact on passing levels, and 3) utility of item disclosure – by synthesizing existing literature in relation to standards in testing. Historically, the controversy over item disclosure has centered on fairness and validity. Proponents of item disclosure stress test takers’ right to know, while opponents argue from a validity perspective. Item disclosure may bias item characteristics, such as difficulty and discrimination, and has consequences on setting passing levels. To date, there has been limited research on the utility of item disclosure for large scale testing. These issues requires ongoing and careful consideration. PMID:26374693

Key Scientific Issues in the Health Risk Assessment of Trichloroethylene

Chiu, Weihsueh A.; Caldwell, Jane C.; Keshava, Nagalakshmi; Scott, Cheryl Siegel

2006-01-01

Trichloroethylene (TCE) is a common environmental contaminant at hazardous waste sites and in ambient and indoor air. Assessing the human health risks of TCE is challenging because of its inherently complex metabolism and toxicity and the widely varying perspectives on a number of critical scientific issues. Because of this complexity, the U.S. Environmental Protection Agency (EPA) drew upon scientific input and expertise from a wide range of groups and individuals in developing its 2001 draft health risk assessment of TCE. This scientific outreach, which was aimed at engaging a diversity of perspectives rather than developing consensus, culminated in 2000 with 16 state-of-the-science articles published together as an Environmental Health Perspectives supplement. Since that time, a substantial amount of new scientific research has been published that is relevant to assessing TCE health risks. Moreover, a number of difficult or controversial scientific issues remain unresolved and are the subject of a scientific consultation with the National Academy of Sciences coordinated by the White House Office of Science and Technology Policy and co-sponsored by a number of federal agencies, including the U.S. EPA. The articles included in this mini-monograph provide a scientific update on the most prominent of these issues: the pharmacokinetics of TCE and its metabolites, mode(s) of action and effects of TCE metabolites, the role of peroxisome proliferator–activated receptor in TCE toxicity, and TCE cancer epidemiology.

Lewis, Tené T; Cogburn, Courtney D; Williams, David R

2015-01-01

Over the past two decades, research examining the impact of self-reported experiences of discrimination on mental and physical health has increased dramatically. Studies have found consistent associations between exposure to discrimination and a wide range of Diagnostic and Statistical Manual of Mental Disorders (DSM)-diagnosed mental disorders as well as objective physical health outcomes. Associations are seen in cross-sectional as well as longitudinal studies and persist even after adjustment for confounding variables, including personality characteristics and other threats to validity. However, controversies remain, particularly around the best approach to measuring experiences of discrimination, the significance of racial/ethnic discrimination versus overall mistreatment, the need to account for "intersectionalities," and the importance of comprehensive assessments. These issues are discussed in detail, along with emerging areas of emphasis including cyber discrimination, anticipatory stress or vigilance around discrimination, and interventions with potential to reduce the negative effects of discrimination on health. We also discuss priorities for future research and implications for interventions and policy.

Diamond, Ian; Abbott, Owen; Jackson, Neil

2003-01-01

As part of the 2001 Census, the One Number Census project estimated and adjusted the Census database for underenumeration. As a result of the highly innovative One Number Census and the Quality Assurance process it encompassed, it was also ensured that robust results could be obtained for each local authority area. This article examines some of the issues and analyses that were undertaken as part of that assessment of the 2001 Census population counts for England and Wales. The article firstly highlights the key issues surrounding the implementation of the 2001 Census fieldwork. The article then explores the 2001 Census results through a series of demographic analyses to illustrate the sorts of issues investigated during the One Number Census Quality Assurance process itself. These analyses look at the patterns contained within the results, and comparisons with key alternative sources of population counts. Overall, these in-depth analyses and investigations provide further credence to the plausibility of the One Number Census results.

Human Health Effects of Biphenyl: Key Findings and Scientific Issues

Background: In support of the Integrated Risk Information System (IRIS), the U.S. Environmental Protection Agency (EPA) has evaluated the human health hazards of biphenyl exposure. Objectives: We review key findings and scientific issues regarding expected human health effects of biphenyl. Methods: Scientific literature from 1926 through September 2012 was critically evaluated to identify potential human health hazards associated with biphenyl exposure. Key issues related to the carcinogenicity and noncancer health hazards of biphenyl were examined based on evidence from experimental animal bioassays and mechanistic studies. Discussion: Systematic consideration of experimental animal studies of oral biphenyl exposure took into account the variety of study designs (e.g., study sizes, exposure levels, and exposure durations) to reconcile differing reported results. The available mechanistic and toxicokinetic evidence supports the hypothesis that male rat urinary bladder tumors arise through urinary bladder calculi formation but is insufficient to hypothesize a mode of action for liver tumors in female mice. Biphenyl and its metabolites may induce genetic damage, but a role for genotoxicity in biphenyl-induced carcinogenicity has not been established. Conclusions: The available health effects data for biphenyl provides suggestive evidence for carcinogenicity in humans, based on increased incidences of male rat urinary bladder tumors at high exposure levels and on female mouse liver tumors. Kidney toxicity is also a potential human health hazard of biphenyl exposure. Citation: Li Z, Hogan KA, Cai C, Rieth S. 2016. Human health effects of biphenyl: key findings and scientific issues.

2002-07-15

To identify key issues affecting women general practitioners in their professional and non-professional lives. A qualitative study using the Delphi technique, with three rounds of data provision circulated to each participant. Coding was used to ensure anonymity. The participants were a purposive sample of 40 women GPs drawn from all Australian States and Territories. The study was conducted between October 1996 and January 1997. Key issues affecting the professional and non-professional lives of women GPs. Some of the key professional issues for women GPs were job satisfaction, balancing work and personal life, autonomy, availability of flexible and part-time work and training, affordability of professional expenses, fair remuneration, and having a voice in decision-making. Key non-professional issues included self-care; time for relationships with a partner, children, family and friends; and time management to allow pursuit of non-medical interests. The conflicting demands made on women GPs diminish their job satisfaction and lead to stress and imbalance in their lives. Recommendations to ameliorate the problems for women GPs include appropriate training, policy formation, financial and other support, and a change in cultural expectations of women GPs by the community, the profession and governments.

NCAP projection displays: key issues for commercialization

NASA Astrophysics Data System (ADS)

Tomita, Akira; Jones, Philip J.

1992-06-01

Recently there has been much interest in a new polymer nematic dispersion technology, often called as NCAP, PDLC, PNLC, LCPC, etc., since projection displays using this technology have been shown to produce much brighter display images than projectors using conventional twisted nematic (TN) lightvalves. For commercializing projection displays based on this polymer nematic dispersion technology, the new materials must not only meet various electro- optic requirements, e.g., operational voltage, `off-state'' scattering angle, voltage holding ratio and hysteresis, but must also be stable over the lifetime of the product. This paper reports recent progress in the development of NCAP based projection displays and discusses some of the key commercialization issues.

[Controversies over the surgical placebo: legal issues and the ethical debate].

Hervé, C; Moutel, G; Meningaud, J P; Wolf, M; Lopes, M

2000-06-17

The debate on controlled surgery trials has had some rather "sensational" repercussions, enlivening the placebo issue. In France, there is a consensus on the ethical conditions necessary for proper protection of individual persons. This consensus has taken on a legal form with the promulgation of the Huriet law. For this reason, all studies and research protocols in medicine and surgery are examined by ethics committees (CCPPRB) who assess the inclusion conditions within the framework of biomedical research and in compliance with the concept that individual participants must be give proper protection. These committees are faced with increasingly complex situations, particularly concerning the pertinence of information give to the participant and the modalities of consent. In France, standard measures were established after a parliamentary debate issuing from a wider public debate. The issue has become a social transaction between biomedical research professionals and the society in general. The international debate over the surgery placebo is an interesting illustration of how mediation institutions, working along the principles of ethical committees, play a key role in social awareness of the ethical issues involved before an innovating practice is initiated. But how legitimate are sensational pieces published in the media, which as is clearly demonstrated with the debate over the surgical placebo, are almost always individual points of view? Shouldn't the debate take into account the contributions of ethical committees which integrate representatives of the social community as well as the importance of a legal framework for individual protection as proposed by the French law? Shouldn't personal points of view be counterbalanced by regularly expressed ethical committee opinions formed after appropriate ethics-oriented discussion going beyond the simple question of "should we do it", a question often dismissed by extreme theoretical arguments that leave unanswered

Dufoe, A.; Guertin, L. A.

2012-12-01

This project looks to help teachers utilize iPad technology in their classrooms as an instructional tool for Earth system science and connections to the Big Ideas in Earth Science. The project is part of Penn State University's National Science Foundation (NSF) Targeted Math Science Partnership grant, with one goal of the grant to help current middle school teachers across Pennsylvania engage students with significant and complex questions of Earth science. The free Apple software iBooks Author was used to create an electronic book for the iPad, focusing on a variety of controversial issues impacting the hydrosphere. The iBook includes image slideshows, embedded videos, interactive images and quizzes, and critical thinking questions along Bloom's Taxonomic Scale of Learning Objectives. Outlined in the introductory iBook chapters are the Big Ideas of Earth System Science and an overview of Earth's spheres. Since the book targets the hydrosphere, each subsequent chapter focuses on specific water issues, including glacial melts, aquifer depletion, coastal oil pollution, marine debris, and fresh-water chemical contamination. Each chapter is presented in a case study format that highlights the history of the issue, the development and current status of the issue, and some solutions that have been generated. The next section includes critical thinking questions in an open-ended discussion format that focus on the Big Ideas, proposing solutions for rectifying the situation, and/or assignments specifically targeting an idea presented in the case study chapter. Short, comprehensive multiple-choice quizzes are also in each chapter. Throughout the iBook, students are free to watch videos, explore the content and form their own opinions. As a result, this iBook fulfills the grant objective by engaging teachers and students with an innovative technological presentation that incorporates Earth system science with current case studies regarding global water issues.

Controversies in gestational diabetes.

PubMed

Nolan, Christopher J

2011-02-01

Gestational diabetes mellitus (GDM) and controversy are old friends. However, several major studies in the field have clarified some of the main issues. There is now no doubt that hyperglycaemia, at levels less than those that occur in overt diabetes, is associated with adverse pregnancy outcomes, such as large-for-gestational age infants, neonatal hyperinsulinism, neonatal hypoglycaemia and pre-eclampsia. We also have evidence now that a standard approach to GDM with diagnosis at 24-28 weeks, dietary advice, self-monitoring of blood glucose and insulin therapy as needed reduces these adverse perinatal outcomes. Unknown, however, is if this same approach is effective at reducing long-term risks of metabolic syndrome, type 2 diabetes and cardiovascular disease in both the mothers and babies. For example, could our management strategies miss critical time points of fuel-mediated injury to the foetus important for the baby's long-term metabolic health? The implications of a recent international consensus statement on new diagnostic criteria for GDM are discussed, as well as issues relating to the timing of diagnosis. The potential place for a risk calculator for adverse outcomes in GDM pregnancy that takes into account glycaemic and non-glycaemic risk factors is considered. Such a tool could help stratify GDM women to different levels of care. Ongoing issues relating to maternal glycaemic and foetal growth targets, and the use of oral hypoglycaemic agents in GDM are discussed. To resolve some of the remaining controversies, further carefully designed randomised controlled trials in GDM with long-term follow-up of both mothers and babies are necessary.

Recent controversy regarding the meaning and usefulness of weak values is reviewed. It is argued that in spite of recent statistical arguments by Ferrie and Combes, experiments with anomalous weak values provide useful amplification techniques for precision measurements of small effects in many realistic situations. The statistical nature of weak values is questioned. Although measuring weak values requires an ensemble, it is argued that the weak value, similarly to an eigenvalue, is a property of a single pre- and post-selected quantum system. This article is part of the themed issue `Second quantum revolution: foundational questions'.

The primary treatment of pancreatic cancer was the topic of the 3rd St. Gallen Conference 2016. A multidisciplinary panel reviewed the current evidence and discussed controversial issues in a moderated consensus session. Here we report on the key expert recommendations. It was generally accepted that radical surgical resection followed by adjuvant chemotherapy offers the only evidence-based treatment with a chance for cure. Initial staging should classify localised tumours as resectable or unresectable (i.e. locally advanced pancreatic cancer) although there remains a large grey-zone of potentially resectable disease between these two categories which has recently been named as borderline resectable, a concept which was generally accepted by the panel members. However, the definition of these borderline-resectable (BR) tumours varies between classifications due to their focus on either (i) technical hurdles (e.g. the feasibility of vascular resection) or (ii) oncological outcome (e.g. predicting the risk of a R1 resection and/or occult metastases). The resulting expert discussion focussed on imaging standards as well as the value of pretherapeutic laparoscopy. Indications for biliary drainage were seen especially before neoadjuvant therapy. Following standard resection, the panel unanimously voted for the use of adjuvant chemotherapy after R0 resection and considered it as a reasonable standard of care after R1 resection, even though the optimal pathologic evaluation and the definition of R0/R1 was the issue of an ongoing debate. The general concept of BR tumours was considered as a good basis to select patients for preoperative therapy, albeit its current impact on the therapeutic strategy was far less clear. Main focus of the conference was to discuss the limits of surgical resection and to identify ways to standardise procedures and to improve curative outcome, including adjuvant and perioperative treatment.

Differences in religious faith-based viewpoints (controversies) on the sanctity of human life, acceptable behaviour, health-care technologies and health-care services contribute to the widespread variations in health care worldwide. Faith-linked controversies include family planning, child protection (especially child marriage, female genital mutilation, and immunisation), stigma and harm reduction, violence against women, sexual and reproductive health and HIV, gender, end-of-life issues, and faith activities including prayer. Buddhism, Christianity, Hinduism, Islam, Judaism, and traditional beliefs have similarities and differences in their viewpoints. Improved understanding by health-care providers of the heterogeneity of viewpoints, both within and between faiths, and their effect on health care is important for clinical medicine, public-health programmes, and health-care policy. Increased appreciation in faith leaders of the effect of their teachings on health care is also crucial. This Series paper outlines some faith-related controversies, describes how they influence health-care provision and uptake, and identifies opportunities for research and increased interaction between faith leaders and health-care providers to improve health care.

The bellerophont controversy revisited

USGS Publications Warehouse

Harper, J.A.; Rollins, H.B.

2000-01-01

An old controversy reestablished itself in the late 1970s and early 1980s that focused on the systematic placement of the enigmatic Bellerophontoidea (informally, "bellerophonts"), a group of planispirally coiled, wholly fossil molluscs. The controversy embraced three fundamental concepts that are based on different philosophical interpretations of shell form, muscle scar patterns, and other preserved shell features: 1) all bellerophonts were monoplacophorans; 2) all bellerophonts were gastropods; and 3) some bellerophonts were monoplacophorans and some were gastropods. A review of the main issues appearing in the literature since the early 1980s indicates that these three philosophical divisions still exist and, indeed, have become entrenched. An examination of the relevant anatomical and shell features of recent gastropods and monoplacophorans, and comparison with preserved features in enigmatic fossil forms, convinces us that the bellerophontoideans and the coiled and high-domed "monoplacophorans" (Cyclomya) were gastropods. Only the flattened, spoon-and cap-shaped monoplacophorans (Tergomya) were true monoplacophorans. We present a hypothetical scheme for the morphological diversification of gastropods from early monoplacophorans that could account for Cyclomya, Bellerophontoidea, Patellogastropoda, and Prosobranchia.

Silica and lung cancer: a controversial issue.

PubMed

Pairon, J C; Brochard, P; Jaurand, M C; Bignon, J

1991-06-01

The role of crystalline silica in lung cancer has long been the subject of controversy. In this article, we review the main experimental and epidemiological studies dealing with this problem. Some evidence for a genotoxic potential of crystalline silica has been obtained in the rare in vitro studies published to date. In vivo studies have shown that crystalline silica is carcinogenic in the rat; the tumour types appear to vary according to the route of administration. In addition, an association between carcinogenic and fibrogenic potency has been observed in various animal species exposed to crystalline silica. An excess of lung cancer related to occupational exposure to crystalline silica is reported in many epidemiological studies, regardless of the presence of silicosis. However, most of these studies are difficult to interpret because they do not correctly take into account associated carcinogens such as tobacco smoke and other occupational carcinogens. An excess of lung cancer is generally reported in studies based on silicosis registers. Overall, experimental and human studies suggest an association between exposure to crystalline silica and an excess of pulmonary malignancies. Although the data available are not sufficient to establish a clear-cut causal relationship in humans, an association between the onset of pneumoconiosis and pulmonary malignancies is probable. In contrast, experimental observations have given rise to a pathophysiological mechanism that might account for a putative carcinogenic potency of crystalline silica.

2013-09-12

To implement peer-led team learning in an online course on controversial issues surrounding medications and the US healthcare system. The course was delivered completely online using a learning management system. Students participated in weekly small-group discussions in online forums, completed 3 reflective writing assignments, and collaborated on a peer-reviewed grant proposal project. In a post-course survey, students reported that the course was challenging but meaningful. Final projects and peer-reviewed assignments demonstrated that primary learning goals for the course were achieved and students were empowered to engage in the healthcare debate. A peer-led team-learning is an effective strategy for an online course offered to a wide variety of student learners. By shifting some of the learning and grading responsibility to students, the instructor workload for the course was rendered more manageable.

Background: In support of the Integrated Risk Information System (IRIS), the U.S. Environmental Protection Agency (EPA) completed a toxicological review of trichloroethylene (TCE) in September 2011, which was the result of an effort spanning > 20 years. Objectives: We summarized the key findings and scientific issues regarding the human health effects of TCE in the U.S. EPA’s toxicological review. Methods: In this assessment we synthesized and characterized thousands of epidemiologic, experimental animal, and mechanistic studies, and addressed several key scientific issues through modeling of TCE toxicokinetics, meta-analyses of epidemiologic studies, and analyses of mechanistic data. Discussion: Toxicokinetic modeling aided in characterizing the toxicological role of the complex metabolism and multiple metabolites of TCE. Meta-analyses of the epidemiologic data strongly supported the conclusions that TCE causes kidney cancer in humans and that TCE may also cause liver cancer and non-Hodgkin lymphoma. Mechanistic analyses support a key role for mutagenicity in TCE-induced kidney carcinogenicity. Recent evidence from studies in both humans and experimental animals point to the involvement of TCE exposure in autoimmune disease and hypersensitivity. Recent avian and in vitro mechanistic studies provided biological plausibility that TCE plays a role in developmental cardiac toxicity, the subject of substantial debate due to mixed results from epidemiologic and rodent studies. Conclusions: TCE is carcinogenic to humans by all routes of exposure and poses a potential human health hazard for noncancer toxicity to the central nervous system, kidney, liver, immune system, male reproductive system, and the developing embryo/fetus.

Socioscientific Issues: A Path Towards Advanced Scientific Literacy and Improved Conceptual Understanding of Socially Controversial Scientific Theories

NASA Astrophysics Data System (ADS)

Pinzino, Dean William

This thesis investigates the use of socioscientific issues (SSI) in the high school science classroom as an introduction to argumentation and socioscientific reasoning, with the goal of improving students' scientific literacy (SL). Current research is reviewed that supports the likelihood of students developing a greater conceptual understanding of scientific theories as well as a deeper understanding of the nature of science (NOS), through participation in informal and formal forms of argumentation in the context of SSI. Significant gains in such understanding may improve a student's ability to recognize the rigor, legitimacy, and veracity of scientific claims and better discern science from pseudoscience. Furthermore, students that participate in significant SSI instruction by negotiating a range of science-related social issues can make significant gains in content knowledge and develop the life-long skills of argumentation and evidence-based reasoning, goals not possible in traditional lecture-based science instruction. SSI-based instruction may therefore help students become responsible citizens. This synthesis also suggests that that the improvements in science literacy and NOS understanding that develop from sustained engagement in SSI-based instruction will better prepare students to examine and scrutinize socially controversial scientific theories (i.e., evolution, global warming, and the Big Bang).

Towards Providing Culturally Aware Nutritional Care for Transgender People: Key Issues and Considerations.

PubMed

Fergusson, Pamela; Greenspan, Nicole; Maitland, Lukas; Huberdeau, Rémy

2018-06-01

Transgender people are an important group for whom access to healthcare is often problematic. Dietitians need to be aware of key issues in transgender health to provide culturally competent clinical nutritional care. This article serves as a primer, clarifying key terms and concepts, exploring the impact of stigma and discrimination on health and nutrition for people from transgender communities, and offering practical advice for nutritional and other related issues. Education for dietitians both pre- and postqualification is an important part of improving care and building skills and awareness of cultural humility. Transgender people may be at increased nutritional risk due to increased risk of cardiovascular disease, HIV, body image issues, and food insecurity. This risk profile, along with the history of trauma both outside and related to the medical community means that there is an urgent need for dietitians to develop practice tools for assessment, care, and referral to improve the nutritional status and well-being of this client group.

Controversy in the allometric application of fixed- versus varying-exponent models: a statistical and mathematical perspective.

PubMed

Tang, Huadong; Hussain, Azher; Leal, Mauricio; Fluhler, Eric; Mayersohn, Michael

2011-02-01

This commentary is a reply to a recent article by Mahmood commenting on the authors' article on the use of fixed-exponent allometry in predicting human clearance. The commentary discusses eight issues that are related to criticisms made in Mahmood's article and examines the controversies (fixed-exponent vs. varying-exponent allometry) from the perspective of statistics and mathematics. The key conclusion is that any allometric method, which is to establish a power function based on a limited number of animal species and to extrapolate the resulting power function to human values (varying-exponent allometry), is infused with fundamental statistical errors.

Veno-venous ECMO: a synopsis of nine key potential challenges, considerations, and controversies

PubMed Central

2014-01-01

Background Following the 2009 H1N1 Influenza pandemic, extracorporeal membrane oxygenation (ECMO) emerged as a viable alternative in selected, severe cases of ARDS. Acute Respiratory Distress Syndrome (ARDS) is a major public health problem. Average medical costs for ARDS survivors on an annual basis are multiple times those dedicated to a healthy individual. Advances in medical and ventilatory management of severe lung injury and ARDS have improved outcomes in some patients, but these advances fail to consistently “rescue” a significant proportion of those affected. Discussion Here we present a synopsis of the challenges, considerations, and potential controversies regarding veno-venous ECMO that will be of benefit to anesthesiologists, surgeons, and intensivists, especially those newly confronted with care of the ECMO patient. We outline a number of points related to ECMO, particularly regarding cannulation, pump/oxygenator design, anticoagulation, and intravascular fluid management of patients. We then address these challenges/considerations/controversies in the context of their potential future implications on clinical approaches to ECMO patients, focusing on the development and advancement of standardized ECMO clinical practices. Summary Since the 2009 H1N1 pandemic ECMO has gained a wider acceptance. There are challenges that still must be overcome. Further investigations of the benefits and effects of ECMO need to be undertaken in order to facilitate the implementation of this technology on a larger scale. PMID:25110462

Sparking controversy: Jean Antoine Nollet and medical electricity south of the Alps.

PubMed

Bertucci, Paola

2005-01-01

The paper considers a significant episode in the history of eighteenth-century electricity: the controversy over the "medicated tubes". Invented by the Italian erudite Gianfrancesco Pivati, the tubes were said to produce instantaneous cures. Jean Antoine Nollet was one of the main actors of the controversy. In 1749, after touring Italy to see for himself the Italian tubes and their effects, he published a report, discrediting Pivati's accounts. This study shows that the report, which has since been the main source for interpretations of the controversy, hides the key role of the Bologna Istituto delle Scienze in promoting Pivati's invention. Relying on manuscript sources, I propose a change of perspective on the controversy that illuminates the world of Italian experimental philosophy during the Enlightenment and its place in the Republic of Letters. I also analyze the reasons for Nollet's silence over the involvement of the Istituto delle Scienze in the controversy and the relevance of medical electricity in the wider context of contemporary electrical experimental philosophy.

Lee, Andrew C K; Phillips, Wendy; Challen, Kirsty; Goodacre, Steve

2012-10-19

Emergency planning in the UK has grown considerably in recent years, galvanised by the threat of terrorism. However, deficiencies in NHS emergency planning were identified and the evidence-base that underpins it is questionable. Inconsistencies in terminologies and concepts also exist. Different models of emergency management exist internationally but the optimal system is unknown. This study examines the evidence-base and evidence requirements for emergency planning in the UK health context. The study involved semi-structured interviews with key stakeholders and opinion leaders. Purposive sampling was used to obtain a breadth of views from various agencies involved in emergency planning and response. Interviews were then analysed using a grounded approach using standard framework analysis techniques. We conducted 17 key informant interviews. Interviewees identified greater gaps in operational than technical aspects of emergency planning. Social and behavioural knowledge gaps were highlighted with regards to how individuals and organisations deal with risk and behave in emergencies. Evidence-based approaches to public engagement and for developing community resilience to disasters are lacking. Other gaps included how knowledge was developed and used. Conflicting views with regards to the optimal configuration and operation of the emergency management system were voiced. Four thematic categories for future research emerged:(i) Knowledge-base for emergency management: Further exploration is needed of how knowledge is acquired, valued, disseminated, adopted and retained.(ii) Social and behavioural issues: Greater understanding of how individuals approach risk and behave in emergencies is required.(iii) Organisational issues in emergencies: Several conflicting organisational issues were identified; value of planning versus plans, flexible versus standardized procedures, top-down versus bottom-up engagement, generic versus specific planning, and reactive versus

Key technology issues for space robotic systems

Schappell, Roger T.

1987-01-01

Robotics has become a key technology consideration for the Space Station project to enable enhanced crew productivity and to maximize safety. There are many robotic functions currently being studied, including Space Station assembly, repair, and maintenance as well as satellite refurbishment, repair, and retrieval. Another area of concern is that of providing ground based experimenters with a natural interface that they might directly interact with their hardware onboard the Space Station or ancillary spacecraft. The state of the technology is such that the above functions are feasible; however, considerable development work is required for operation in this gravity-free vacuum environment. Furthermore, a program plan is evolving within NASA that will capitalize on recent government, university, and industrial robotics research and development (R and D) accomplishments. A brief summary is presented of the primary technology issues and physical examples are provided of the state of the technology for the initial operational capability (IOC) system as well as for the eventual final operational capability (FOC) Space Station.

Controversy matters: Impacts of topic and solution controversy on the perceived credibility of a scientist who advocates.

PubMed

Beall, Lindsey; Myers, Teresa A; Kotcher, John E; Vraga, Emily K; Maibach, Edward W

2017-01-01

In this article, we focus on the potential influence of a scientist's advocacy position on the public's perceived credibility of scientists as a whole. Further, we examine how the scientist's solution position (information only, non-controversial, and controversial) affects the public's perception of the scientist's motivation for sharing information about specific issues (flu, marijuana, climate change, severe weather). Finally, we assess how perceived motivations mediate the relationship between solution position and credibility. Using data from a quota sample of American adults obtained by Qualtrics (n = 2,453), we found that in some conditions advocating for a solution positively predicted credibility, while in one condition, it negatively predicted scientist credibility. We also found that the influence of solution position on perceived credibility was mediated by several motivation perceptions; most notably through perception that the scientist was motivated to: (a) serve the public and (b) persuade the public. Further results and implications are discussed.

2004-08-06

Application for contestable government-research funding and ethical approval requires researchers to outline how their intended research project contributes to Maori development or advancement. When formulating their research proposals, the key issues for researchers are research utility, defining Maori, informed consent, confidentiality, issues with human tissues and genetic material, participant remuneration and recognition (koha), intellectual property, and involvement of local Maori health or social services. The most common Maori responsiveness issues in research applications can be readily approached by researchers who address straightforward methodological concerns, by working through precedents established by peers and colleagues, as well as by working with end-users of their research.

Increasing use of the new oral anticoagulants (NOACs) - dabigatran, rivaroxaban, and apixaban - has prompted considerable discussion in the medical community even as warfarin remains the mainstay of therapy. This article raises 10 controversial issues regarding the use of NOACs for stroke prevention in patients with atrial fibrillation, and offers a review of the latest available evidence. We provide a brief overview of the mechanism and dosing of these drugs, as well as a summary of the key clinical trials that have brought them into the spotlight. Comparative considerations relative to warfarin such as NOAC safety, efficacy, bleeding risk, reversibility, drug-transitioning and use in patients well controlled on warfarin are addressed. Use in select populations such as the elderly, those with coronary disease, renal impairment, or on multiple anti-platelet drugs is also discussed. Finally, we consider such specific issues as comparative efficacy, off-label use, cost, rebound and management during events. Ultimately, the rise of the NOACs to mainstream use will depend on further data and clinical experience amongst the medical community. © The Author(s) 2014.

Human Health Effects of Dichloromethane: Key Findings and Scientific Issues

Schlosser, Paul M.; Bale, Ambuja S.; Gibbons, Catherine F.; Wilkins, Amina

2014-01-01

Background: The U.S. EPA’s Integrated Risk Information System (IRIS) completed an updated toxicological review of dichloromethane in November 2011. Objectives: In this commentary we summarize key results and issues of this review, including exposure sources, identification of potential health effects, and updated physiologically based pharmacokinetic (PBPK) modeling. Methods: We performed a comprehensive review of primary research studies and evaluation of PBPK models. Discussion: Hepatotoxicity was observed in oral and inhalation exposure studies in several studies in animals; neurological effects were also identified as a potential area of concern. Dichloromethane was classified as likely to be carcinogenic in humans based primarily on evidence of carcinogenicity at two sites (liver and lung) in male and female B6C3F1 mice (inhalation exposure) and at one site (liver) in male B6C3F1 mice (drinking-water exposure). Recent epidemiologic studies of dichloromethane (seven studies of hematopoietic cancers published since 2000) provide additional data raising concerns about associations with non-Hodgkin lymphoma and multiple myeloma. Although there are gaps in the database for dichloromethane genotoxicity (i.e., DNA adduct formation and gene mutations in target tissues in vivo), the positive DNA damage assays correlated with tissue and/or species availability of functional glutathione S-transferase (GST) metabolic activity, the key activation pathway for dichloromethane-induced cancer. Innovations in the IRIS assessment include estimation of cancer risk specifically for a presumed sensitive genotype (GST-theta-1+/+), and PBPK modeling accounting for human physiological distributions based on the expected distribution for all individuals 6 months to 80 years of age. Conclusion: The 2011 IRIS assessment of dichloromethane provides insights into the toxicity of a commonly used solvent. Citation: Schlosser PM, Bale AS, Gibbons CF, Wilkins A, Cooper GS. 2015.

2012-05-01

Lately, glaciers have been subjects of unceasing controversy. Current debate about planned hydroelectric facilities—a US7- to 10-billion megaproject—in a pristine glacierized area of Patagonia, Chile [Romero Toledo et al., 2009; Vince, 2010], has raised anew the matter of how glaciologists and global change experts can contribute their knowledge to civic debates on important issues. There has been greater respect for science in this controversy than in some previous debates over projects that pertain to glaciers, although valid economic motivations again could trump science and drive a solution to the energy supply problem before the associated safety and environmental problems are understood. The connection between glaciers and climate change—both anthropogenic and natural—is fundamental to glaciology and to glaciers' practical importance for water and hydropower resources, agriculture, tourism, mining, natural hazards, ecosystem conservation, and sea level [Buytaert et al., 2010; Glasser et al., 2011]. The conflict between conservation and development can be sharper in glacierized regions than almost anywhere else. Glaciers occur in spectacular natural landscapes, but they also supply prodigious exploitable meltwater.

Understanding of the pathophysiological basis of Alzheimer's disease (AD) is increasing rapidly and a variety of potential treatment modalities have emerged based on these improved mechanistic insights. The optimal way of proceeding with disease-modifying drug development remains to be clarified and controversies have emerged regarding the definition of Alzheimer's disease, the participation of mild cognitive impairment patients in clinical trials, the definition of disease modification, the potential impediments to satisfaction from patients receiving disease-modifying therapy, the importance of add-on therapy with symptomatic agents, the optimal clinical trial design to demonstrate disease modification, the best means of minimizing time spent in Phase II of drug development, the potential role of adaptive designs in clinical trials, the use of enrichment designs in clinical trials, the role of biomarkers in clinical trials, the treatment of advanced patients with disease-modifying agents, and distinctions between disease modification and disease prevention. The questions surrounding these issues must be resolved as disease-modifying therapies for AD are advanced. These controversies are framed and potential directions towards resolution described.

Textual analysis of tobacco editorials: how are Key media gatekeepers framing the issues?

PubMed

Smith, Katherine Clegg; Wakefield, Melanie

2005-01-01

The news media's potential to promote awareness of health issues is established, and media advocacy is now an important tool in combating tobacco use. This study examines newspaper editors' perspectives of tobacco-related issues. This study presents a textual analysis of tobacco-related editorials. The data consist of editorials on tobacco from a sample of 310 U.S. daily newspapers over the course of 1 year (2001). Data were sampled from a random one-third of the days per month, yielding 162 editorials for analysis. A qualitative textual analysis was conducted. Each editorial was coded for theme, position, and frame. We analyzed the topics gaining editorial attention and the arguments made to support various perspectives. Editorials discussed a variety of both positive and negative news events, largely conveying support for tobacco-control objectives. Various organizing frames were used-supporting policy interventions, condemning the industry, highlighting individual rights, and expressing general cynicism were most prevalent. Editors largely promoted tobacco-control efforts, particularly policy advances. There was, however, little coverage of key issues such as health effects and addiction-perhaps because they are no longer perceived to be contentious. Advocates should seek to address this area and minimize the cynicism of key media gatekeepers to avoid undermining policy and individual change efforts.

This report identifies key human-performance-related issues associated with Next Generation Air Transportation System (NextGen) research in the NASA NextGen-Airspace Project. Four Research Focus Areas (RFAs) in the NextGen-Airspace Project - namely Separation Assurance (SA), Airspace Super Density Operations (ASDO), Traffic Flow Management (TFM), and Dynamic Airspace Configuration (DAC) - were examined closely. In the course of the research, it was determined that the identified human performance issues needed to be analyzed in the context of NextGen operations rather than through basic human factors research. The main gaps in human factors research in NextGen were found in the need for accurate identification of key human-systems related issues within the context of specific NextGen concepts and better design of the operational requirements for those concepts. By focusing on human-system related issues for individual concepts, key human performance issues for the four RFAs were identified and described in this report. In addition, mixed equipage airspace with components of two RFAs were characterized to illustrate potential human performance issues that arise from the integration of multiple concepts.

Student Identity Considerations and Implications Associated with Socioscientific Issues Instruction

NASA Astrophysics Data System (ADS)

Ruzek, Mitchel James

The purpose of this investigation was to explore how aspects of identity, perceived levels of controversy, and the strength of a student's attachment to their controversial identity relate to conceptual understanding and knowledge acquisition during socioscientific issues (SSI) based instruction in a biology classroom. The knowledge gained from this study will have the capacity to enhance our understanding of the role that attachment to identity plays during SSI negotiation. Additionally, insight was gained into the role played by aspects of identity in conceptual understanding of scientifically controversial topics during SSI based instruction. This study contributed to the existing knowledge base in science education by illuminating processes involved in socioscientific issue navigation among students of differing perceptions of controversy as well as students who held aspects of controversial identity that may or may not interact with the specific issues chosen. Students demonstrated evidence of variations of reasoning, justification, perception of controversy, and aspects of knowledge gain as they negotiated the issues of marijuana safety and fast food legality. Additionally, evidence was provided that showed general knowledge gain throughout the group during socioscientific issues instruction. It has been said that one of the appeals of the SSI instructional model is that is serves not only as a context for the delivery of content, but acts as a catalyst for various forms of epistemological beliefs and research into the development of conceptual and psychological knowledge structures (Zeidler, 2013). This investigation supports the deeper understanding of the contribution of controversy perception to epistemology as well as conceptual and psychological knowledge structures during SSI navigation.

Clinical trials are crucial to improve cancer treatment but recruitment is difficult. Optimised patient information has been recognised as a key issue. In line with the increasing focus on patients' perspectives in health care, we aimed to study patients' opinions about the written information used in three clinical trials for breast cancer. Primary data collection was done in focus group interviews with breast cancer patient advocates. Content analysis identified three major themes: comprehensibility, emotions and associations, and decision making. Based on the advocates' suggestions for improvements, 21 key issues were defined and validated through a questionnaire in an independent group of breast cancer patient advocates. Clear messages, emotionally neutral expressions, careful descriptions of side effects, clear comparisons between different treatment alternatives and information about the possibility to discontinue treatment were perceived as the most important issues. Patients' views of the information in clinical trials provide new insights and identify key issues to consider in optimising future written information and may improve recruitment to clinical cancer trials. © 2010 Blackwell Publishing Ltd.

The breast implant controversy.

PubMed

Cook, R R; Harrison, M C; LeVier, R R

1994-02-01

The breast implant issue is a "bad news/good news" story. For many women with implants, the controversy has caused a fair degree of anxiety which may or may not be resolved as further information becomes available. It has also taken its toll on Dow Corning. Whole lines of medical products have been eliminated or are being phase out. The development of new medical applications has been terminated. As a consequence, employees have lost their jobs. What the effect will be on the biomedical industry as a whole remains to be seen (11). While silicones have been an important component in various medical devices, it is likely that other materials can be used as replacements. However, suppliers of non-silicone materials are also reevaluating their role in this market. For example, Du Pont, the nation's largest chemical company, has determined that the unpredictable and excessive costs of doing business with manufacturers of implantable medical devices no longer justifies the unrestricted sale of standard raw materials into this industry. Other companies are quietly following suit. On the up side, it is possible that the research being driven by this controversy will result in a greater understanding of the immunologic implications of xenobiotics, of the importance of nonbiased observations, of the need for ready access to valid data sets, and of the opportunity for valid scientific information to guide legal decisions. Only time will tell.

Controversial issues in treating the dental patient with autism.

PubMed

Rada, Robert E

2010-08-01

The author conducted a literature review to investigate concerns that parents of a child with an autism spectrum disorder may have when oral health care is provided to the child. The author conducted a search of PubMed using the terms "mercury," "fluoride," "nitrous oxide," "antibiotics," "gluten," "casein," "acetaminophen" and "dentistry" each with the term "autism." He identified controlled studies and literature reviews in both medical and alternative medical literature that were related to areas of importance to oral health care workers. The use of mercury, fluoride, nitrous oxide, antibiotic agents and acetaminophen all are sources of controversy between dentistry and the parents of children who have autism. The author found that patients who have autism frequently also have allergies, immune system problems, gastrointestinal disturbances and seizures. Dental health care workers must be aware of these comorbid conditions so they can provide optimal care to the children with autism spectrum disorders. The author found two distinct theories as to what causes autism: one that focuses on genetic causes, and one that focuses on the impact of the environment. He found that the interpretation of these theories might affect parents' concerns about various dental treatments. Dentists treating patients who have autism may need to provide more than standard patient care, as the use of time-tested dental treatment and prevention modalities may be questioned or refused by parents.

Controversies in Alzheimer’s disease drug development

2010-01-01

Understanding of the pathophysiological basis of Alzheimer’s disease (AD) is increasing rapidly and a variety of potential treatment modalities have emerged based on these improved mechanistic insights. The optimal way of proceeding with disease-modifying drug development remains to be clarified and controversies have emerged regarding the definition of Alzheimer’s disease, the participation of mild cognitive impairment patients in clinical trials, the definition of disease modification, the potential impediments to satisfaction from patients receiving disease-modifying therapy, the importance of add-on therapy with symptomatic agents, the optimal clinical trial design to demonstrate disease modification, the best means of minimizing time spent in Phase II of drug development, the potential role of adaptive designs in clinical trials, the use of enrichment designs in clinical trials, the role of biomarkers in clinical trials, the treatment of advanced patients with disease-modifying agents, and distinctions between disease modification and disease prevention. The questions surrounding these issues must be resolved as disease-modifying therapies for AD are advanced. These controversies are framed and potential directions towards resolution described.

Nghiem, Nhung; Genç, Murat; Blakely, Tony

2013-01-01

Pricing policies such as taxes and subsidies are important tools in preventing and controlling a range of threats to public health. This is particularly so in tobacco and alcohol control efforts and efforts to change dietary patterns and physical activity levels as a means of addressing increases in noncommunicable diseases. To understand the potential impact of pricing policies, it is critical to understand the nature of price elasticities for consumer products. For example, price elasticities are key parameters in models of any food tax or subsidy that aims to quantify health impacts and cost-effectiveness. We detail relevant terms and discuss key issues surrounding price elasticities to inform public health research and intervention studies. PMID:24028228

Practical issues in quantum-key-distribution postprocessing

NASA Astrophysics Data System (ADS)

Fung, Chi-Hang Fred; Ma, Xiongfeng; Chau, H. F.

2010-01-01

Quantum key distribution (QKD) is a secure key generation method between two distant parties by wisely exploiting properties of quantum mechanics. In QKD, experimental measurement outcomes on quantum states are transformed by the two parties to a secret key. This transformation is composed of many logical steps (as guided by security proofs), which together will ultimately determine the length of the final secret key and its security. We detail the procedure for performing such classical postprocessing taking into account practical concerns (including the finite-size effect and authentication and encryption for classical communications). This procedure is directly applicable to realistic QKD experiments and thus serves as a recipe that specifies what postprocessing operations are needed and what the security level is for certain lengths of the keys. Our result is applicable to the BB84 protocol with a single or entangled photon source.

Controversial medical and agri-food biotechnology: a cultivation analysis.

PubMed

Bauer, Martin W

2002-04-01

Whether biotechnology is one or several developments is not clear. Once distinctions are required, the question is: Which one prevails? When the good, the bad, and the ugly settle, where do they fall? Evaluation implies distinction, and representation drives attitude. The controversies over biotechnology are fertile ground on which to study these issues. The imports of genetically modified (GM) soya into Europe in 1996-97 and the cloning of Dolly the sheep from adult cells in 1997 changed the symbolic environment for genetic engineering. The ensuing public controversies came to focus mainly on field trials of GM crops and food labeling. This paper will explore the relationship between quality press coverage and public perception, in particular the cultivation of the contrast between "desirable" biomedical (RED) and "undesirable" agri-food (GREEN) biotechnology in Britain. The argument draws on a systematic analysis of the British press coverage of biotechnology from 1973 to 1999 and analysis of public perceptions in 1996 and 1999. The paper concludes that the debate over GM crops and food ingredients fostered the RED-GREEN contrast among the newspaper-reading public, thereby shielding RED biotechnology from public controversy, and ushered in a realignment of the regulatory framework in 2000.

Addressing controversies in science education: a pragmatic approach to evolution education

NASA Astrophysics Data System (ADS)

Hildebrand, David; Bilica, Kimberly; Capps, John

2008-09-01

Science education controversies typically prove more intractable than those in scientific research because they involve a wider range of considerations (e.g., epistemic, social, ethical, political, and religious). How can educators acknowledge central issues in a controversy (such as evolution)? How can such problems be addressed in a way that is ethically sensitive and intellectually responsible? Drawing in part on pragmatic philosopher John Dewey, our solution is politically proactive, philosophically pragmatic, and grounded in research. Central to our proposal is (1) steps toward creating a philosophical “total attitude” that is democratic, imaginative, and hypothetical; (2) a deeper understanding of how scientific theories can be pragmatically true; and (3) an assessment of differing pedagogical approaches for teaching evolution in the classroom.

Contact dermatitis: facts and controversies.

2013-01-01

The history of contact dermatitis (CD) is inseparable from the history of the patch test, and the patch test is inseparable from the pioneer in the field, Josef Jadassohn (1860-1936). Despite the fact that we have been diagnosing, treating, and investigating the condition for more than 100 years, there are still many unsolved questions and controversies, which show no signs of coming to an end in the foreseeable future. This contribution reviews and highlights some of the disagreements and discrepancies associated with CD. For example: • What is the real sensitizer in balsam of Peru, one of the most common allergens, and what, if any, is the value of a low-balsam diet? • Is benzalkonium chloride, which has well-known and undisputed irritant properties, a contact allergen as well? • Is cocamidopropyl betaine (CABP) a common contact allergen and what is the actual sensitizer in CABP allergy the molecule itself, or impurities, or intermediaries in its synthesis? • How can the significant differences in the prevalence of sensitization of formaldehyde (FA, a common cause of contact allergy) between the United States (8%-9%) and Europe (2%-3%) be explained? • What is the relationship between formaldehyde releasers (FRs) allergy and an FA allergy? Should we recommend that FA-allergic patients also avoid FRs, and, if so, to what extent? • What is the true frequency of lanolin allergy? This issue remains enigmatic despite the expenditure of thousands of dollars and the innumerable hours spent investigating this subject. • What is the basis behind the so-called "lanolin paradox"? This label was coined in 1996 and is still a matter of controversy. • Is there such a thing as systemic CD from nickel, and, if so, to what extent? Is there a cross-reactivity or concomitant sensitization between nickel and cobalt?These are some of the controversial problems discussed. We have selected the ones that we consider to be of special interest and importance to the

Scaling up in international health: what are the key issues?

PubMed

Mangham, Lindsay J; Hanson, Kara

2010-03-01

The term 'scaling up' is now widely used in the international health literature, though it lacks an agreed definition. We review what is meant by scaling up in the context of changes in international health and development over the last decade. We argue that the notion of scaling up is primarily used to describe the ambition or process of expanding the coverage of health interventions, though the term has also referred to increasing the financial, human and capital resources required to expand coverage. We discuss four pertinent issues in scaling up the coverage of health interventions: the costs of scaling up coverage; constraints to scaling up; equity and quality concerns; and key service delivery issues when scaling up. We then review recent progress in scaling up the coverage of health interventions. This includes a considerable increase in the volume of aid, accompanied by numerous new health initiatives and financing mechanisms. There have also been improvements in health outcomes and some examples of successful large-scale programmes. Finally, we reflect on the importance of obtaining a better understanding of how to deliver priority health interventions at scale, the current emphasis on health system strengthening and the challenges of sustaining scaling up in the prevailing global economic environment.

[On controversies around the Oedipus Complex].

Drwiega, Marek

2002-01-01

In the article the author would like to draw the readers' attention to one of the central issues of psychoanalysis, i.e. Oedipus complex. In the development of the psychoanalysis the classical conception of Oedipus complex presented by Freud gave rise to a severe criticism both on the part of some psychoanalysts, especially women such as e.g. Melanie Klein, and on the part of ethnographers such as B. Malinowski. In the paper the author presents the main controversies concerning this interesting discussion. The fact of the matter is that the Oedipus complex is a hotly debated subject, not only from the cultural point of view but also within the psychoanalytical movement.

Sugar substitutes: Health controversy over perceived benefits

PubMed Central

Tandel, Kirtida R.

2011-01-01

Sugar is an inseparable part of the food we consume. But too much sugar is not ideal for our teeth and waistline. There have been some controversial suggestions that excessive sugar may play an important role in certain degenerative diseases. So artificial sweeteners or artificially sweetened products continue to attract consumers. A sugar substitute (artificial sweetener) is a food additive that duplicates the effect of sugar in taste, but usually has less food energy. Besides its benefits, animal studies have convincingly proven that artificial sweeteners cause weight gain, brain tumors, bladder cancer and many other health hazards. Some kind of health related side effects including carcinogenicity are also noted in humans. A large number of studies have been carried out on these substances with conclusions ranging from “safe under all conditions” to “unsafe at any dose”. Scientists are divided in their views on the issue of artificial sweetener safety. In scientific as well as in lay publications, supporting studies are often widely referenced while the opposing results are de-emphasized or dismissed. So this review aims to explore the health controversy over perceived benefits of sugar substitutes. PMID:22025850

Sexuality education for adolescents is one of the most controversial topics in the field of child health. In the past decade, policymakers in India have also struggled with the issue and there has been greater public discourse. However, policymaking and public discussions on adolescent sexuality education are frequently fueled by religious, social, and cultural values, while receiving scant scientific attention. To meet the needs of an expanding young population in India, scientific evidence for best practices must be kept at the core of policymaking in the context of sexuality education for adolescents.

Survey of controversial issues of end-of-life treatment decisions in Korea: similarities and discrepancies between healthcare professionals and the general public

PubMed Central

2013-01-01

Introduction End-of-life (EOL) treatment issues have recently gained societal attention after the Korean Supreme Court’s ruling that the presumed wishes of an elderly woman in a persistent vegetative state (PVS) should be honored. We tried to evaluate what Koreans thought about controversial issues regarding EOL treatments. Methods We surveyed Koreans with the following questions: 1) are ventilator-dependent PVS patients candidates for end-of life treatment decisions? 2) Is withholding and withdrawing EOL treatment the same thing? 3) In an unconscious, terminally ill patient, whose wishes are unknown, how should EOL decisions be made? 4) How should we settle disagreement amongst medical staff and the patient’s family on EOL decisions? Results One thousand Koreans not working in healthcare and five hundred healthcare professionals responded to the survey. Fifty-seven percent of Koreans not working in healthcare and sixty seven percent of Korean healthcare professionals agreed that ventilator-dependent PVS patients are candidates for EOL treatment decisions. One quarter of all respondents regarded withholding and withdrawing EOL treatment as equal. Over 50% thought that EOL treatment decisions should be made through discussions between the physician and the patient’s family. For conflict resolution, 75% of Koreans not working in healthcare preferred direct settlement between the medical staff and the patient’s family while 55% of healthcare professionals preferred the hospital ethics committee. Conclusions Unsettled issues in Korea regarding EOL treatment decision include whether to include ventilator-dependent PVS patients as candidates of EOL treatment decision and how to sort out disagreements regarding EOL treatment decisions. Koreans viewed withholding and withdrawing EOL treatment issues differently. PMID:24093519

Diagnosis of Celiac Disease: Taking a Bite Out of the Controversy.

PubMed

Turner, Justine M

2018-06-01

Celiac disease is a common autoimmune disorder of the small intestine, triggered by an immunological response to the gluten present in wheat, barley, and rye in individuals who are genetically at risk. A key to reducing the complications of this disease is early diagnosis, preferably in childhood, and consuming a lifelong gluten-free diet once diagnosis is confirmed. Yet, the diagnosis of celiac disease is often considerably delayed, exposing patients to needless suffering and morbidity. It is also difficult to confirm histologically if dietary gluten has been restricted prior to obtaining a diagnostic biopsy, a significant problem given the current growing popularity of gluten-free diets. Furthermore, failure to understand or follow current guidelines means physicians may recommend patients commence the gluten-free diet before initiating referral to a gastroenterologist. Finally, adding further confusion, pediatric guidelines in Europe support a diagnosis based on serology rather than on histology, whereas those based in North America do not. The purpose of this review is to discuss these issues and other controversies in the diagnosis of celiac disease and to consider ways to optimize diagnosis across the lifespan.

1981-05-01

The Two Cultures schism is a persistent problem in our society. For over a century, scientific spokesmen and literary critics, from T. H. Huxley and M. Arnold to C. P. Snow and F. R. Leavis, have been involved in the Two Cultures issue. This article examines the evolution of the controversy between the ''scientific'' and ''humanistic'' elements of Western culture and its relation to educational policies. The division and antagonism between these two cultures appears to have arisen from differences in the human attitudes that they are preceived to engender. ''Scientific'' professionalism has been associated with a progressive optimism and self-assurance that nurture a broad humanitarianism, while the ''literary'' tradition is characterized by restraint, acceptance, and a more selective humanism.

Static nature of performance reporting systems in health care sector has resulted in inconsistent, incomparable, time consuming, and static performance reports that are not able to transparently reflect a round picture of performance and effectively support healthcare managers' decision makings. So, the healthcare sector needs interactive performance management tools such as performance dashboards to measure, monitor, and manage performance more effectively. The aim of this article was to identify key issues that need to be addressed for developing high-quality performance dashboards in healthcare sector. A literature review was established to search electronic research databases, e-journals collections, and printed journals, books, dissertations, and theses for relevant articles. The search strategy interchangeably used the terms of "dashboard", "performance measurement system", and "executive information system" with the term of "design" combined with operator "AND". Search results (n=250) were adjusted for duplications, screened based on their abstract relevancy and full-text availability (n=147) and then assessed for eligibility (n=40). Eligible articles were included if they had explicitly focused on dashboards, performance measurement systems or executive information systems design. Finally, 28 relevant articles included in the study. Creating high-quality performance dashboards requires addressing both performance measurement and executive information systems design issues. Covering these two fields, identified contents were categorized to four main domains: KPIs development, Data Sources and data generation, Integration of dashboards to source systems, and Information presentation issues. This study implies the main steps to develop dashboards for the purpose of performance management. Performance dashboards developed on performance measurement and executive information systems principles and supported by proper back-end infrastructure will result in

The search strategy interchangeably used the terms of “dashboard”, “performance measurement system”, and “executive information system” with the term of “design” combined with operator “AND”. Search results (n=250) were adjusted for duplications, screened based on their abstract relevancy and full-text availability (n=147) and then assessed for eligibility (n=40). Eligible articles were included if they had explicitly focused on dashboards, performance measurement systems or executive information systems design. Finally, 28 relevant articles included in the study. Results: Creating high-quality performance dashboards requires addressing both performance measurement and executive information systems design issues. Covering these two fields, identified contents were categorized to four main domains: KPIs development, Data Sources and data generation, Integration of dashboards to source systems, and Information presentation issues. Conclusion: This study implies the main steps to develop dashboards for the purpose of performance management. Performance dashboards developed on performance measurement and executive information systems principles and

Patients with advanced chronic kidney disease (CKD) have a high burden of physical and psychosocial symptoms, poor outcomes, and high costs of care. Current paradigms of care for this highly vulnerable population are variable, prognostic and assessment tools are limited, and quality of care, particularly regarding conservative and palliative care, is suboptimal. The KDIGO Controversies Conference on Supportive Care in CKD reviewed the current state of knowledge in order to define a roadmap to guide clinical and research activities focused on improving the outcomes of people living with advanced CKD, including those on dialysis. An international group of multidisciplinary experts in CKD, palliative care, methodology, economics, and education identified the key issues related to palliative care in this population. The conference led to a working plan to address outstanding issues in this arena, and this executive summary serves as an output to guide future work, including the development of globally applicable guidelines.

Students' socio-scientific reasoning on controversies from the viewpoint of education for sustainable development

NASA Astrophysics Data System (ADS)

Simonneaux, Laurence; Simonneaux, Jean

2009-09-01

In this article, we study third-year university students' reasoning about three controversial socio-scientific issues from the viewpoint of education for sustainable development: local issues (the reintroduction of bears in the Pyrenees in France, wolves in the Mercantour) and a global one (global warming). We used the theoretical frameworks of social representations and of socio-scientific reasoning. Students' reasoning varies according to the issues, in particular because of their emotional proximity with the issues and their socio-cultural origin. About this kind of issues, it seems pertinent to integrate into the operations of socio-scientific reasoning not only the consideration of values, but also the analysis of the modes of governance and the place given to politics.

Professional Hubris and its Consequences: Why Organizations of Health-Care Professions Should Not Adopt Ethically Controversial Positions.

PubMed

Vogelstein, Eric

2016-05-01

In this article, I argue that professional healthcare organizations such as the AMA and ANA ought not to take controversial stances on professional ethics. I address the best putative arguments in favor of taking such stances, and argue that none are convincing. I then argue that the sort of stance-taking at issue has pernicious consequences: it stands to curb critical thought in social, political, and legal debates, increase moral distress among clinicians, and alienate clinicians from their professional societies. Thus, because there are no good arguments in favor of stance-taking and at least some risks in doing so, professional organizations should refrain from adopting the sort of ethically controversial positions at issue. © 2015 John Wiley & Sons Ltd.

Marshall, Julie

2003-01-01

This paper discusses a number of key challenges facing professionals who work with people who have communication disabilities. The challenges are related to working internationally and in a cross-culturally competent way. Each challenge is discussed, drawing on material from a range of sources, including the papers in the final 2003 edition of FOLIA PHONIATRICA ET LOGOPAEDICA ('International and Cross-Cultural Issues'). The challenges discussed cover how experiences from majority world countries can be used to benefit services elsewhere, 'mainstreaming' commitment to cross-cultural competence, learning from relationships with other professionals, influencing research practice, responding to requests to work internationally and finally, dealing with cultural differences that challenge working practices. Some solutions are suggested and additional questions posed. Copyright 2003 S. Karger AG, Basel

Background Controversy about the introduction of a non-dispensing pharmacist in primary care practice hampers implementation. Objective The aim of this study is to systematically map the debate on this new role for pharmacists amongst all stakeholders to uncover and understand the controversy and consensus. Primary health care in the Netherlands. Method Q methodology. 163 participants rank-ordered statements on issues concerning the integration of a non-dispensing pharmacist in primary care practice. Stakeholder perspectives on the role of the non-dispensing pharmacist and pharmaceutical care in primary care. Results This study identified the consensus on various features of the non-dispensing pharmacist role as well as the financial, organisational and collaborative aspects of integrating a non-dispensing pharmacist in primary care practice. Q factor analysis revealed four perspectives: "the independent community pharmacist", "the independent clinical pharmacist", "the dependent clinical pharmacist" and "the medication therapy management specialist". These four perspectives show controversies to do with the level of professional independency of the non-dispensing pharmacist and the level of innovation of task performance. Conclusion Despite the fact that introducing new professional roles in healthcare can lead to controversy, the results of this Q study show the potential of a non-dispensing pharmacist as a pharmaceutical care provider and the willingness for interprofessional collaboration. The results from the POINT intervention study in the Netherlands will be an important next step in resolving current controversies.

Adjunctive use of the diode laser in non-surgical periodontal therapy: exploring the controversy.

PubMed

Porteous, Mary Sornborger; Rowe, Dorothy J

2014-04-01

Despite the controversy regarding clinical efficacy, dental hygienists use the diode laser as an adjunct to non-surgical periodontal therapy. The technique to maximize successful laser therapy outcome is controversial as well. The purpose of this review is to explore the scientific foundation of the controversy surrounding the use of the diode laser as an adjunct to non-surgical periodontal therapy. Further, this paper addresses the weaknesses in study design, the heterogeneity of methodology in the published clinical studies, especially the laser parameters, and how these issues impact the collective clinical and microbial data, and thus conclusions regarding clinical efficacy. Evaluation of the literature identifies possible mechanisms that could contribute to the varied, often conflicting results among laser studies that are the foundation of the controversy surrounding clinical efficacy. These mechanisms include current paradigms of periodontal biofilm behavior, tissue response to laser therapy being dependent on tissue type and health, and that the successful therapeutic treatment window is specific to the target tissue, biofilm composition, laser wavelength, and laser energy delivered. Lastly, this paper discusses laser parameters used in the various clinical studies, and how their diversity contributes to the controversy. Although this review does not establish clinical efficacy, it does reveal the scientific foundation of the controversy and the need for standardized, well designed randomized controlled clinical trials to develop specific guidelines for using the laser as an adjunct to non-surgical periodontal therapy. Using evidence-based laser guidelines would allow dental hygienists to provide more effective non-surgical periodontal care.

Breast vs. bottle: a new controversy.

PubMed

Caruncho, E S

1979-01-01

The infant feeding controversy had its roots in the early 1960s, when the declining birth rate in industrialized countries led the multinational baby food manufacturers to look to the fast growing populations of the 3rd World to bolster their sales. The connection between infant formula, malnutrition, and infant mortality has been increasingly recognized by the World Health Organization and other groups and individuals. The expense of infant formula, overdilution by impoverished parents attempting to stretch the food budget, and poor sanitary conditions made millions of 3rd World babies victims of malnutrition, infectious diseases, and premature death. In 1974, the British public interest group called War on Want launched an international campaign against the aggressive promotional practices of the infant formula manufacturers. A nonbinding agreement between the International Council of Infant Food Industries and their critics in Geneva in 1979 was regarded as a truce rather than a solution to the controversy, but worldwide attention was attracted to the infant feeding issue. Scientific research has confirmed the advantages of breast feeding in providing immunity as well as optimal nutrition and contraceptive protection. Although greater convenience, necessity of working outside the home, or insufficient milk lead some mothers to bottle feed, misleading and aggressive promotional campaigns of the infant feeding companies have been very effective in persuading mothers of all income levels to choose bottle feeding. With increasing realization of the benefits of breast feeding, efforts are now underway to reverse the trends.

Behavioral consequences of conflict-oriented health news coverage: the 2009 mammography guideline controversy and online information seeking.

Weeks, Brian E; Friedenberg, Laura M; Southwell, Brian G; Slater, Jonathan S

2012-01-01

Building on channel complementarity theory and media-system dependency theory, this study explores the impact of conflict-oriented news coverage of health issues on information seeking online. Using Google search data as a measure of behavior, we demonstrate that controversial news coverage of the U.S. Preventive Services Task Force's November 2009 recommendations for changes in breast cancer screening guidelines strongly predicted the volume of same-day online searches for information about mammograms. We also found that this relationship did not exist 1 year prior to the coverage, during which mammography news coverage did not focus on the guideline controversy, suggesting that the controversy frame may have driven search behavior. We discuss the implications of these results for health communication scholars and practitioners.

How did the fracking controversy emerge in the period 2010-2012?

PubMed

Mazur, Allan

2016-02-01

In 2010-2012, the controversy over fracking grew rapidly, first in the United States, and then internationally. An important step was the anti-fracking documentary film Gasland. With help from celebrity sources, the film was produced and won a prize at the Sundance Film Festival by early 2010 and had an Oscar nomination by early 2011, in the meantime popularizing potent images of hazard including tainted aquifers and ignitable water running from kitchen faucets. During this period, major US news organizations paid little attention to the issue. The offshore Deepwater Horizon disaster of April 2010 spurred The New York Times to prolific reporting on potential risks of the new onshore technique for extracting shale gas. With flagship news coverage, the controversy had by 2012 gained wide media attention that evoked public concern and opposition, spreading from the United States to other nations. © The Author(s) 2014.

Although less common than other musculoskeletal injuries, spinal trauma may lead to significantly more disability and costs. During the last 2 decades there was substantial improvement in our understanding of the basic patterns of spinal fractures leading to more reliable classification and injury severity assessment systems but also rapid developments in surgical techniques. Despite these advancements, there remain unresolved issues concerning the management of these injuries. At this moment there is persistent controversy within the spinal trauma community, which can be grouped under 6 headings. First of all there is still no unanimity on the role and timing of medical and surgical interventions for patients with associated neurologic injury. The same is also true for type and timing of surgical intervention in multiply injured patients. In some common injury types like odontoid fractures and burst type (A3-A4) fractures in thoracolumbar spine, there is wide variation in practice between operative versus nonoperative management without clear reasons. Also, the role of different surgical approaches and techniques in certain injury types are not clarified yet. Methods of nonoperative management and care of elderly patients with concurrent complex disorders are also areas where there is no consensus. In this overview article the main reasons for these controversies are reviewed and the possible ways for resolutions are discussed.

Key issues in human resource planning for home support workers in Canada.

Keefe, Janice M; Knight, Lucy; Martin-Matthews, Anne; Légaré, Jacques

2011-01-01

This paper is a synthesis of research on recruitment and retention challenges for home support workers (HSWs) in Canada. Home support workers (HSWs) provide needed support with personal care and daily activities to older persons living in the community. Literature (peer reviewed, government, and non-government documents) published in the past decade was collected from systematic data base searches between January and September 2009, and yielded over 100 references relevant to home care human resources for older Canadians. Four key human resource issues affecting HSWs were identified: compensation, education and training, quality assurance, and working conditions. To increase the workforce and retain skilled employees, employers can tailor their marketing strategies to specific groups, make improvements in work environment, and learn about what workers value and what attracts them to home support work. Understanding these HR issues for HSWs will improve recruitment and retention strategies for this workforce by helping agencies to target their limited resources. Given the projected increase in demand for these workers, preparations need to begin now and consider long-term strategies involving multiple policy areas, such as health and social care, employment, education, and immigration.

Diabetes mellitus and tuberculosis facts and controversies

PubMed Central

2013-01-01

Tuberculosis (TB) and diabetes mellitus (DM) are both important health issues. A bidirectional association between them has been demonstrated by many researchers. The link of DM and TB is more prominent in developing countries where TB is endemic and the burden of diabetes mellitus is increasing. The association between diabetes and tuberculosis may be the next challenge for global tuberculosis control worldwide. Proper planning and collaboration are necessary to reduce the dual burden of diabetes and TB. One model similar to the TB-HIV program for prevention, screening and treatment of both diseases can be the best approach. In this paper, we review existing data and discuss the matters of controversy that would be helpful for determining research priorities in different countries. PMID:24360398

Family-friendliness in business as a key issue for the future.

PubMed

Stutzer, Erich

2012-01-01

These days family-friendliness is a key issue for the future of businesses. Investments in a family conscious personnel policy are considered as forward-looking decisions in companies. This happens against the background of a sustainable personnel policy in times of a decrease in the number of employable persons, an increasing shortage of skilled workers and an ageing workforce. Family-friendly working conditions are becoming a key factor in the competition for staff. When choosing an employer, family-friendliness has become a crucial topic. Employment participation and skills of women, especially of mothers, have greatly increased. To facilitate the realisation of their wish to return to paid employment, however, measures to reconcile work and family are required. Family-conscious measures have been proven to lead to higher employee productivity. Job satisfaction and motivation of employees and accumulation of human capital increase, absenteeism declines, the return of investment rises. Fields of activity for family-friendly measures in companies range from working arrangements, parental leave and re-entry programmes and various child care offers to services for families. In connection with the demographic development the demand for a better reconciliation of work and elder care should in future become ever more important, just as the upkeep of the occupational skills and working capacity of an ageing workforce. Family-friendliness has to become an integral part of corporate culture.

The dental amalgam controversy: a review

PubMed Central

Feuer, George; Injeyan, H Stephen

1996-01-01

In spite of the long history of mercury amalgam as a dental restorative material, its use continues to be controversial. Mercury vapour is continuously released from dental amalgam and is ultimately absorbed into a variety of tissues. Experimental data have demonstrated that the uptake, tissue retention and excretion of mercury from dental amalgam is significant. Evidence has accumulated indicating a relationship between tissue mercury levels and a multitude of clinical manifestations. However, the clinical significance of mercury toxicity from dental amalgams is a matter for debate. The literature is devoid of randomized clinical trials that are rigorously designed to address this issue. Thus, although research data renders the notion of amalgam safety questionable, the dental community appears determined to continue its use as long as unequivocal evidence correlating amalgam mercury toxicity to specific clinical conditions is lacking.

2016-01-01

Fertility preservation in the young cancer survivor is recognized as a key survivorship issue by the American Society of Clinical Oncology and the American Society of Reproductive Medicine. Thus, health-care providers should inform women about the effects of cancer therapy on fertility and should discuss the different fertility preservation options available. It is also recommended to refer women expeditiously to a fertility specialist in order to improve counseling. Women’s age, diagnosis, presence of male partner, time available, and preferences regarding use of donor sperm influence the selection of the appropriate fertility preservation option. Embryo and oocyte cryopreservation are the standard techniques used while ovarian tissue cryopreservation is new, yet promising. Despite the importance of fertility preservation for cancer survivors’ quality of life, there are still communication and financial barriers faced by women who wish to pursue fertility preservation.

Key issues review: evolution on rugged adaptive landscapes

NASA Astrophysics Data System (ADS)

Obolski, Uri; Ram, Yoav; Hadany, Lilach

2018-01-01

Adaptive landscapes represent a mapping between genotype and fitness. Rugged adaptive landscapes contain two or more adaptive peaks: allele combinations with higher fitness than any of their neighbors in the genetic space. How do populations evolve on such rugged landscapes? Evolutionary biologists have struggled with this question since it was first introduced in the 1930s by Sewall Wright. Discoveries in the fields of genetics and biochemistry inspired various mathematical models of adaptive landscapes. The development of landscape models led to numerous theoretical studies analyzing evolution on rugged landscapes under different biological conditions. The large body of theoretical work suggests that adaptive landscapes are major determinants of the progress and outcome of evolutionary processes. Recent technological advances in molecular biology and microbiology allow experimenters to measure adaptive values of large sets of allele combinations and construct empirical adaptive landscapes for the first time. Such empirical landscapes have already been generated in bacteria, yeast, viruses, and fungi, and are contributing to new insights about evolution on adaptive landscapes. In this Key Issues Review we will: (i) introduce the concept of adaptive landscapes; (ii) review the major theoretical studies of evolution on rugged landscapes; (iii) review some of the recently obtained empirical adaptive landscapes; (iv) discuss recent mathematical and statistical analyses motivated by empirical adaptive landscapes, as well as provide the reader with instructions and source code to implement simulations of evolution on adaptive landscapes; and (v) discuss possible future directions for this exciting field.
