Scholarship on patients accessing unproven stem cell interventions is dominated by research addressing 'stem cell tourism' to such countries as China, India, Mexico, and the Ukraine. However, clinics marketing 'adipose-derived mesenchymal stem cell treatments' are proliferating across the USA. These businesses typically claim to operate in compliance with federal regulations, but careful review of their commercial practices suggests that such clinics are marketing unapproved and noncompliant biological drugs.

Transforming clinical practice guidelines and clinical pathways into fast-and-frugal decision trees to improve clinical care strategies.

PubMed

Djulbegovic, Benjamin; Hozo, Iztok; Dale, William

2018-02-27

Contemporary delivery of health care is inappropriate in many ways, largely due to suboptimal Q5 decision-making. A typical approach to improve practitioners' decision-making is to develop evidence-based clinical practice guidelines (CPG) by guidelines panels, who are instructed to use their judgments to derive practice recommendations. However, mechanisms for the formulation of guideline judgments remains a "black-box" operation-a process with defined inputs and outputs but without sufficient knowledge of its internal workings. Increased explicitness and transparency in the process can be achieved by implementing CPG as clinical pathways (CPs) (also known as clinical algorithms or flow-charts). However, clinical recommendations thus derived are typically ad hoc and developed by experts in a theory-free environment. As any recommendation can be right (true positive or negative), or wrong (false positive or negative), the lack of theoretical structure precludes the quantitative assessment of the management strategies recommended by CPGs/CPs. To realize the full potential of CPGs/CPs, they need to be placed on more solid theoretical grounds. We believe this potential can be best realized by converting CPGs/CPs within the heuristic theory of decision-making, often implemented as fast-and-frugal (FFT) decision trees. This is possible because FFT heuristic strategy of decision-making can be linked to signal detection theory, evidence accumulation theory, and a threshold model of decision-making, which, in turn, allows quantitative analysis of the accuracy of clinical management strategies. Fast-and-frugal provides a simple and transparent, yet solid and robust, methodological framework connecting decision science to clinical care, a sorely needed missing link between CPGs/CPs and patient outcomes. We therefore advocate that all guidelines panels express their recommendations as CPs, which in turn should be converted into FFTs to guide clinical care. © 2018 John Wiley & Sons, Ltd.

The American Academy of Orthopaedic Surgeons (AAOS) has developed Appropriate Use Criteria (AUC) for Management of Carpal Tunnel Syndrome. Evidence-based information, in conjunction with the clinical expertise of physicians, was used to develop the criteria to improve patient care and obtain best outcomes while considering the subtleties and distinctions necessary in making clinical decisions. To provide the evidence foundation for this AUC, the AAOS Evidence-Based Medicine Unit provided the writing panel and voting panel with the 2016 AAOS Clinical Practice Guideline titled Management of Carpal Tunnel Syndrome Evidence-Based Clinical Practice Guideline. The Management of Carpal Tunnel Syndrome AUC clinical patient scenarios were derived from indications typical of patients with suspected carpal tunnel syndrome in clinical practice, as well as from current evidence-based clinical practice guidelines and supporting literature to identify the appropriateness of treatments. The 135 patient scenarios and 6 treatments were developed by the writing panel, a group of clinicians who are specialists in this AUC topic. Next, a separate, multidisciplinary, voting panel (made up of specialists and nonspecialists) rated the appropriateness of treatment of each patient scenario using a 9-point scale to designate a treatment as Appropriate (median rating, 7 to 9), May Be Appropriate (median rating, 4 to 6), or Rarely Appropriate (median rating, 1 to 3).

Using electronic clinical practice audits as needs assessment to produce effective continuing medical education programming.

2012-01-01

The traditional needs assessment used in developing continuing medical education programs typically relies on surveying physicians and tends to only capture perceived learning needs. Instead, using tools available in electronic medical record systems to perform a clinical audit on a physician's practice highlights physician-specific practice patterns. The purpose of this study was to test the feasibility of implementing an electronic clinical audit needs assessment process for family physicians in Canada. A clinical audit of 10 preventative care interventions and 10 chronic disease interventions was performed on family physician practices in Alberta, Canada. The physicians used the results from the audit to produce personalized learning needs, which were then translated into educational programming. A total of 26 family practices and 4489 patient records were audited. Documented completion rates for interventions ranged from 13% for ensuring a patient's tetanus vaccine is current to 97% of pregnant patients receiving the recommended prenatal vitamins. Electronic medical record-based needs assessments may provide a better basis for developing continuing medical education than a more traditional survey-based needs assessment. This electronic needs assessment uses the physician's own patient outcome information to assist in determining learning objectives that reflect both perceived and unperceived needs.

Individualized assessment and phenomenological psychology.

PubMed

Fischer, C T

1979-04-01

Although there is growing openness to tailoring of assessment procedures and reports to the particular client, these efforts typically have been sporadic and incomplete. This article reviews a systematic approach to individualized assessment, one whose practices are referred to as collaborative, contextual, and interventional. Clinical examples of these practices are presented in terms of their grounding in phenomenological psychology. Prior to that, themes such as intentionality, situatedness, dialectics, structuralism, and hermeneutics are introduced briefly. Phenomenological psychology as such is not seen here as necessary for all individualized practices, but it is seen as a critical touchpoint for development of theory and further practices.

To review psychiatrists' attitudes and actual practice on the use of typical and atypical antipsychotics in the elderly. Audit data were collected from 18-old-age psychiatry units across Australia. The attitudes of old age psychiatrists and their perceptions of the efficacy, tolerability and clinical usefulness of antipsychotics were examined. The medications used for 321 patients were audited, and the attitudes of the 57 prescribing doctors were assessed. All available atypicals were prescribed and reported as more efficacious and clinically useful than typicals. Adverse events perceived by doctors as an obstacle to prescribing were more frequent than reported adverse event rates in product information. All diagnostic groups improved. Off-label use comprised almost 22% in this sample. Adverse events are impediments to prescribing, more so with typical than atypical antipsychotics. All available atypicals were used and appeared effective in this elderly population.

Surveys show GPs use placebos in clinical practice and reported prevalence rates vary widely. To explore GPs' perspectives on clinical uses of placebos. A web-based survey of 783 UK GPs' use of placebos in clinical practice. Qualitative descriptive analysis of written responses ('comments') to three open-ended questions. Comments were classified into three categories: (i) defining placebos and their effects in general practice; (ii) ethical, societal and regulatory issues faced by doctors and (iii) reasons why a doctor might use placebos and placebo effects in clinical practice. GPs typically defined placebos as lacking something, be that adverse or beneficial effects, known mechanism of action and/or scientific evidence. Some GPs defined placebos positively as having potential to benefit patients, primarily through psychological mechanisms. GPs described a broad array of possible harms and benefits of placebo prescribing, reflecting fundamental bioethical principles, at the level of the individual, the doctor-patient relationship, the National Health Service and society. While some GPs were adamant that there was no place for placebos in clinical practice, others focused on the clinically beneficial effects of placebos in primary care. This study has elucidated specific costs, benefits and ethical barriers to placebo use as perceived by a large sample of UK GPs. Stand-alone qualitative work would provide a more in-depth understanding of GPs' views. Continuing education and professional guidance could help GPs update and contextualize their understanding of placebos and their clinical effects. © The Author 2014.

Part of the fabric and mostly right: an ethnography of ethics in clinical practice.

To describe how ethics is practised in a health care setting, and to ascertain whether there was interest in establishing clinical ethics support services. Observations and interviews undertaken between April and November 2012 in a large NSW urban hospital with newborn care, maternity and oncology departments and analysed by coding and categorising the data. Key themes in the participants' attitudes to professional ethics were identified. Ethics is not typically an explicit feature of clinical deliberations, and clinicians tend to apply basic ethical principles when ethical problems are identified. They also discuss difficult decisions with colleagues, and try to resolve ethical differences by discussion. Participants judged the ethics of clinical practice to be "mostly right", primarily because ethics is "part of the fabric" of everyday clinical work that aspires to "optimising care". Nevertheless, most clinicians would welcome ethics support because ethics is integral to health care practice, is not always "done well", and may be the source of conflict. Ethics is very much a part of the fabric of clinical practice, and the ethical challenges that arise in patient care in this particular setting are generally managed adequately. However, many clinicians have concerns about the ethical aspects of some practices and decisions, and believe that access to expert ethics support would be useful. Helping clinicians to provide ethically sound patient care should be a priority for health care providers across Australia.

ABSTRACT Background Identifying PD‐specific biomarkers in biofluids will greatly aid in diagnosis, monitoring progression, and therapeutic interventions. PD biomarkers have been limited by poor discriminatory power, partly driven by heterogeneity of the disease, variability of collection protocols, and focus on de novo, unmedicated patients. Thus, a platform for biomarker discovery and validation in well‐characterized, clinically typical, moderate to advanced PD cohorts is critically needed. Methods BioFIND (Fox Investigation for New Discovery of Biomarkers in Parkinson's Disease) is a cross‐sectional, multicenter biomarker study that established a repository of clinical data, blood, DNA, RNA, CSF, saliva, and urine samples from 118 moderate to advanced PD and 88 healthy control subjects. Inclusion criteria were designed to maximize diagnostic specificity by selecting participants with clinically typical PD symptoms, and clinical data and biospecimen collection utilized standardized procedures to minimize variability across sites. Results We present the study methodology and data on the cohort's clinical characteristics. Motor scores and biospecimen samples including plasma are available for practically defined off and on states and thus enable testing the effects of PD medications on biomarkers. Other biospecimens are available from off state PD assessments and from controls. Conclusion Our cohort provides a valuable resource for biomarker discovery and validation in PD. Clinical data and biospecimens, available through The Michael J. Fox Foundation for Parkinson's Research and the National Institute of Neurological Disorders and Stroke, can serve as a platform for discovering biomarkers in clinically typical PD and comparisons across PD's broad and heterogeneous spectrum. © 2016 The Authors.

User-centered design to improve clinical decision support in primary care.

A growing literature has demonstrated the ability of user-centered design to make clinical decision support systems more effective and easier to use. However, studies of user-centered design have rarely examined more than a handful of sites at a time, and have frequently neglected the implementation climate and organizational resources that influence clinical decision support. The inclusion of such factors was identified by a systematic review as "the most important improvement that can be made in health IT evaluations." (1) Identify the prevalence of four user-centered design practices at United States Veterans Affairs (VA) primary care clinics and assess the perceived utility of clinical decision support at those clinics; (2) Evaluate the association between those user-centered design practices and the perceived utility of clinical decision support. We analyzed clinic-level survey data collected in 2006-2007 from 170 VA primary care clinics. We examined four user-centered design practices: 1) pilot testing, 2) provider satisfaction assessment, 3) formal usability assessment, and 4) analysis of impact on performance improvement. We used a regression model to evaluate the association between user-centered design practices and the perceived utility of clinical decision support, while accounting for other important factors at those clinics, including implementation climate, available resources, and structural characteristics. We also examined associations separately at community-based clinics and at hospital-based clinics. User-centered design practices for clinical decision support varied across clinics: 74% conducted pilot testing, 62% conducted provider satisfaction assessment, 36% conducted a formal usability assessment, and 79% conducted an analysis of impact on performance improvement. Overall perceived utility of clinical decision support was high, with a mean rating of 4.17 (±.67) out of 5 on a composite measure. "Analysis of impact on performance improvement" was the only user-centered design practice significantly associated with perceived utility of clinical decision support, b=.47 (p<.001). This association was present in hospital-based clinics, b=.34 (p<.05), but was stronger at community-based clinics, b=.61 (p<.001). Our findings are highly supportive of the practice of analyzing the impact of clinical decision support on performance metrics. This was the most common user-centered design practice in our study, and was the practice associated with higher perceived utility of clinical decision support. This practice may be particularly helpful at community-based clinics, which are typically less connected to VA medical center resources. Published by Elsevier B.V.

Constrained physical therapist practice: an ethical case analysis of recommending discharge placement from the acute care setting.

PubMed

Nalette, Ernest

2010-06-01

Constrained practice is routinely encountered by physical therapists and may limit the physical therapist's primary moral responsibility-which is to help the patient to become well again. Ethical practice under such conditions requires a certain moral character of the practitioner. The purposes of this article are: (1) to provide an ethical analysis of a typical patient case of constrained clinical practice, (2) to discuss the moral implications of constrained clinical practice, and (3) to identify key moral principles and virtues fostering ethical physical therapist practice. The case represents a common scenario of discharge planning in acute care health facilities in the northeastern United States. An applied ethics approach was used for case analysis. The decision following analysis of the dilemma was to provide the needed care to the patient as required by compassion, professional ethical standards, and organizational mission. Constrained clinical practice creates a moral dilemma for physical therapists. Being responsive to the patient's needs moves the physical therapist's practice toward the professional ideal of helping vulnerable patients become well again. Meeting the patient's needs is a professional requirement of the physical therapist as moral agent. Acting otherwise requires an alternative position be ethically justified based on systematic analysis of a particular case. Skepticism of status quo practices is required to modify conventional individual, organizational, and societal practices toward meeting the patient's best interest.

Gaussian processes for personalized e-health monitoring with wearable sensors.

2013-01-01

Advances in wearable sensing and communications infrastructure have allowed the widespread development of prototype medical devices for patient monitoring. However, such devices have not penetrated into clinical practice, primarily due to a lack of research into "intelligent" analysis methods that are sufficiently robust to support large-scale deployment. Existing systems are typically plagued by large false-alarm rates, and an inability to cope with sensor artifact in a principled manner. This paper has two aims: 1) proposal of a novel, patient-personalized system for analysis and inference in the presence of data uncertainty, typically caused by sensor artifact and data incompleteness; 2) demonstration of the method using a large-scale clinical study in which 200 patients have been monitored using the proposed system. This latter provides much-needed evidence that personalized e-health monitoring is feasible within an actual clinical environment, at scale, and that the method is capable of improving patient outcomes via personalized healthcare.

Manifesto: towards a clinically-oriented psychometrics.

New technologies to collect patient - reported outcomes have substantially solved the challenge of integrating a questionnaire in a busy clinical practice. At Memorial Sloan Kettering, we have been collecting patient reported outcomes electronically for many years. Our experience confirms the predicted benefits of obtaining patient reported outcomes but has also raised serious concerns about whether instruments developed for the research setting are appropriate for routine clinical use. We summarize four principles for a clinically - relevant psychometrics. First, minimize patient burden: the use of a large number of items for a single domain may be of interest for research but additional items have little clinical utility. Secondly, use simplified language: patients who do not have good language skills are typically excluded from research studies but will nonetheless present in clinical practice. Third, avoid dumb questions: many questionnaire items are inappropriate when applied to a more general population. Fourth, what works for the group may not work for the individual: group level statistics used to validate survey instruments can obscure problems when applied to a subgroup of patients. There is a need for a clinically-oriented psychometrics to help design, test, and evaluate questionnaires that would be used in routine practice. Developing statistical methods to optimize questionnaires will be highly challenging but needed to bring the potential of patient reported outcomes into widespread clinical use.

2013-01-01

Development or synthesis of the best clinical research is in itself insufficient to change practice. Knowledge translation (KT) is an emerging field focused on moving knowledge into practice, which is a non-linear, dynamic process that involves knowledge synthesis, transfer, adoption, implementation, and sustained use. Successful implementation requires using KT strategies based on theory, evidence, and best practice, including tools and processes that engage knowledge developers and knowledge users. Tools can provide instrumental help in implementing evidence. A variety of theoretical frameworks underlie KT and provide guidance on how tools should be developed or implemented. A taxonomy that outlines different purposes for engaging in KT and target audiences can also be useful in developing or implementing tools. Theoretical frameworks that underlie KT typically take different perspectives on KT with differential focus on the characteristics of the knowledge, knowledge users, context/environment, or the cognitive and social processes that are involved in change. Knowledge users include consumers, clinicians, and policymakers. A variety of KT tools have supporting evidence, including: clinical practice guidelines, patient decision aids, and evidence summaries or toolkits. Exemplars are provided of two KT tools to implement best practice in management of neck pain-a clinician implementation guide (toolkit) and a patient decision aid. KT frameworks, taxonomies, clinical expertise, and evidence must be integrated to develop clinical tools that implement best evidence in the management of neck pain.

Disconnects in pedagogy and practice in community health nursing clinical experiences: Qualitative findings of a mixed method study.

Pijl-Zieber, Em M; Barton, Sylvia; Awosoga, Olu; Konkin, Jill

2015-10-01

Many baccalaureate schools of nursing are using non-traditional placements for undergraduate community health clinical rotations. These placements occur at agencies not organizationally affiliated with the health care system and they typically do not employ registered nurses (RNs). In this paper, we describe the qualitative findings of a mixed method study that explored these gaps as they relate to pre-registration nursing students' preparation for community health roles. While non-traditional community health placements offer unique opportunities for learning through carefully crafted service learning pedagogy, these placements also present challenges for student preparation for practice in community health roles. The theory-practice gap and the gap between the expected and actual performance of new graduates are accentuated through the use of non-traditional community clinical experiences. These gaps are not necessarily due to poor pedagogy, but rather due to the perceptions and values of the stakeholders involved: nursing students, community health nursing faculty, and community health nurses. New ways must be developed between academe and community health practice areas to provide students with opportunities to develop competence for practice. Copyright © 2015 Elsevier Ltd.

On art and science: an epistemic framework for integrating social science and clinical medicine.

PubMed

Wasserman, Jason Adam

2014-06-01

Calls for incorporating social science into patient care typically have accounted for neither the logistic constraints of medical training nor the methodological fallacies of utilizing aggregate "social facts" in clinical practice. By elucidating the different epistemic approaches of artistic and scientific practices, this paper illustrates an integrative artistic pedagogy that allows clinical practitioners to generate social scientific insights from actual patient encounters. Although there is no shortage of calls to bring social science into medicine, the more fundamental processes of thinking by which art and science proceed have not been addressed to this end. As such, the art of medical practice is conceptualized as an innate gift, and thus little is done to cultivate it. Yet doing so is more important than ever because uncertainty in diagnosing and treating chronic illnesses, the most significant contemporary mortality risks, suggests a re-expanding role for clinical judgment. © The Author 2014.

Varieties of clinical reasoning.

PubMed

Bolton, Jonathan W

2015-06-01

Clinical reasoning comprises a variety of different modes of inference. The modes that are practiced will be influenced by the sociological characteristics of the clinical settings and the tasks to be performed by the clinician. This article presents C.S. Peirce's typology of modes of inference: deduction, induction and abduction. It describes their differences and their roles as stages in scientific argument. The article applies the typology to reasoning in clinical settings. The article describes their differences, and their roles as stages in scientific argument. It then applies the typology to reasoning in typical clinical settings. Abduction is less commonly taught or discussed than induction and deduction. However, it is a common mode of inference in clinical settings, especially when the clinician must try to make sense of a surprising phenomenon. Whether abduction is followed up with deductive and inductive verification is strongly influenced by situational constraints and the cognitive and psychological stamina of the clinician. Recognizing the inevitability of abduction in clinical practice and its value to discovery is important to an accurate understanding of clinical reasoning. © 2015 John Wiley & Sons, Ltd.

Clinical productivity of primary care nurse practitioners in ambulatory settings.

PubMed

Xue, Ying; Tuttle, Jane

Nurse practitioners are increasingly being integrated into primary care delivery to help meet the growing demand for primary care. It is therefore important to understand nurse practitioners' productivity in primary care practice. We examined nurse practitioners' clinical productivity in regard to number of patients seen per week, whether they had a patient panel, and patient panel size. We further investigated practice characteristics associated with their clinical productivity. We conducted cross-sectional analysis of the 2012 National Sample Survey of Nurse Practitioners. The sample included full-time primary care nurse practitioners in ambulatory settings. Multivariable survey regression analyses were performed to examine the relationship between practice characteristics and nurse practitioners' clinical productivity. Primary care nurse practitioners in ambulatory settings saw an average of 80 patients per week (95% confidence interval [CI]: 79-82), and 64% of them had their own patient panel. The average patient panel size was 567 (95% CI: 522-612). Nurse practitioners who had their own patient panel spent a similar percent of time on patient care and documentation as those who did not. However, those with a patient panel were more likely to provide a range of clinical services to most patients. Nurse practitioners' clinical productivity was associated with several modifiable practice characteristics such as practice autonomy and billing and payment policies. The estimated number of patients seen in a typical week by nurse practitioners is comparable to that by primary care physicians reported in the literature. However, they had a significantly smaller patient panel. Nurse practitioners' clinical productivity can be further improved. Copyright © 2016 Elsevier Inc. All rights reserved.

The Prevention of Hemorrhagic Stroke

Raymond, J.; Mohr, JP; the TEAM-ARUBA collaborative groups

2008-01-01

Summary There is currently no evidence that preventive treatment of unruptured aneurysms or AVMs is beneficial and randomized trials have been proposed to address this clinical uncertainty. Participation in a trial may necessitate a shift of point of view compared to a certain habitual clinical mentality. A review of the ethical and rational principles governing the design and realization of a trial may help integrate clinical research into expert clinical practices. The treatment of unruptured aneurysms and AVMs remains controversial, and data from observational studies cannot provide a normative basis for clinical decisions. Prevention targets healthy individuals and hence has an obligation of results. There is no opposition between the search for objective facts using scientific methods and the ethics of medical practice since a good practice cannot forbid physicians the means to define what could be beneficial to patients. Perhaps the most difficult task is to recognize the uncertainty that is crucial to allow resorting to trial methodology. The reasoning that is used in research and analysis differs from the casuistic methods typical of clinical work, but clinical judgement remains the dominant factor that decides both who enters the trial and to whom the results of the trial will apply. Randomization is still perceived as a difficult and strange method to integrate into normal practice, but in the face of uncertainty it assures the best chances for the best outcome to each participant. Some tension exists between scientific methods and normal practice, but they need to coexist if we are to progress at the same time we care for patients. PMID:20557736

Reducing the Environmental Impact of Clinical Laboratories.

Healthcare is a significant contributor to environmental impact but this has received little attention. The typical laboratory uses far more energy and water per unit area than the typical office building. There is a need to sensitise laboratories to the importance of adopting good environmental practices. Since this comes at an initial cost, it is vital to obtain senior management support. Convincing management of the various tangible and intangible benefits that can accrue in the long run should help achieve this support. Many good environmental practices do not have a cost but will require a change in the culture and mind-set of the organisation. Continuing education and training are important keys to successful implementation of good practices. There is a need to undertake a rigorous cost-benefit analysis of every change that is introduced in going green. The adoption of good practices can eventually lead to ISO certification if this is desired. This paper provides suggestions that will allow a laboratory to start going green. It will allow the industry to enhance its corporate citizenship whilst improving its competitive advantage for long-term.

Substance use disorder and compulsory commitment to care: a care-ethical decision-making framework.

PubMed

Nicolini, Marie; Vandenberghe, Joris; Gastmans, Chris

2017-11-29

In the era of deinstitutionalisation of psychiatric patients, steady or even increasing rates of compulsory commitment to care (CCC) are an intriguing phenomenon to analyse. From a clinical, legal and ethical perspective, CCC continues to be a controversial practice in psychiatry, and perhaps even more so when applied to patients with severe substance use disorder (SUD). Several reasons make it controversial. The lack of consensus about the benefits of CCC and professional disagreement about what mental illness and autonomy mean in the case of SUD make it difficult to apply ethically sound clinical decision-making in CCC. Also, the medico-legal framework underlying CCC use sometimes appears to foster the use of reductionist clinical evaluation. Layered on top of these issues is how stakeholders view coercion. There is a discrepancy between clinicians' and patients' perception of coercion, which leads to clinician-patient differences on whether CCC is necessary. Moreover, the way in which the evaluation is typically carried out influences patients' perception of coercion and subsequently their motivation for participating fully in treatment. In this article, we explore the value of care ethics, often applied to care practices such as nursing, when applied to more procedural medical practices, such as decision-making regarding CCC. The care-ethical approach views decision-making as part of a dynamic care process, within which the lived experience, interpretative dialogue and promotion of dignity are core features. Embracing this new framework means a paradigm shift in when the therapeutic relationship begins, namely, investing in it occurs while conducting an evaluation for a possible CCC procedure. Unlike in current typical evaluations, early cultivation of the therapeutic relationship enables the patient to participate in the definition of his needs, reduces perceived coercion and negative emotions and enhances treatment motivation. Finally, implications of this novel approach for clinical practice are formulated and discussed. © 2017 Nordic College of Caring Science.

Clinical trials are considered the gold standard for examining drug efficacy and for approval of new drugs. Medical databases and population surveillance registries are valuable resources for post-approval observational research, which are increasingly used in studies of benefits and risk of new cancer drugs. Here, we address the challenges in translating endpoints from oncology trials to observational studies. Registry-based cohort studies can investigate real-world safety issues – including previously unrecognized concerns – by examining rare endpoints or multiple endpoints at once. In contrast to clinical trials, observational cohort studies typically do not exclude real-world patients from clinical practice, such as old and frail patients with comorbidity. The observational cohort study complements the clinical trial by examining the effectiveness of interventions applied in clinical practice and by providing evidence on long-term clinical outcomes, which are often not feasible to study in a clinical trial. Various endpoints can be included in clinical trials, such as hard endpoints, soft endpoints, surrogate endpoints, and patient-reported endpoints. Each endpoint has it strengths and limitations for use in research studies. Endpoints used in oncology trials are often not applicable in observational cohort studies which are limited by the setting of standard clinical practice and by non-standardized endpoint determination. Observational studies can be more helpful moving research forward if they restrict focus to appropriate and valid endpoints. PMID:27354827

Distinguishing between different tremor disorders can be challenging. Some tremor disorders are thought to have typical tremor characteristics: the current study aims to provide sensitivity and specificity for five 'typical' tremor phenomena. Retrospectively, we examined 210 tremor patients referred for electrophysiological recordings between January 2008 and January 2014. The final clinical diagnosis was used as the gold standard. The first step was to determine whether patients met neurophysiological criteria for their type of tremor. Once established, we focused on 'typical' characteristics: tremor frequency decrease upon loading (enhanced physiological tremor (EPT)), amplitude increase upon loading, distractibility and entrainment (functional tremor (FT)), and intention tremor (essential tremor (ET)). The prevalence of these phenomena in the 'typical' group was compared to the whole group. Most patients (87%) concurred with all core clinical neurophysiological criteria for their tremor type. We found a frequency decrease upon loading to be a specific (95%), but not a sensitive (42%) test for EPT. Distractibility and entrainment both scored high on sensitivity (92%, 91%) and specificity (94%, 91%) in FT, whereas a tremor amplitude increase was specific (92%), but not sensitive (22%). Intention tremor was a specific finding in ET (85%), but not a sensitive test (45%). Combination of characteristics improved sensitivity. In this study, we retrospectively determined sensitivity and specificity for five 'typical' tremor characteristics. Characteristics proved specific, but few were sensitive. These data on tremor phenomenology will help practicing neurologists to improve distinction between different tremor disorders. Copyright © 2016 Elsevier Ltd. All rights reserved.

Background and purpose New ideas, methods, and technologies spread through cultures through typical patterns described by diffusion of innovation (DOI) theory. Professional cultures, including the physical therapy profession, have distinctive features and traditions that determine the adoption of practice innovation. The Consolidated Framework for Implementation Research (CFIR) proposes a framework of innovation implementation specific to health care services. While the CFIR has been applied to medical and nursing practice, it has not been extended to rehabilitation professions. The purpose of this qualitative study was to verify the CFIR factors in outpatient physical therapy practice. Design Through a nomination process of area rehabilitation managers and area directors of clinical education, 2 exemplar, outpatient, privately owned physical therapy clinics were identified as innovation practices. A total of 18 physical therapists (PTs), including 3 owners and a manager, participated in the study. Methods The 2 clinics served as case studies within a qualitative approach of directed content analysis. Data were collected through observation, spontaneous, unstructured questioning, workflow analysis, structured focus group sessions, and artifact analysis including clinical documents. Focus group data were transcribed. All the data were analyzed and coded among 4 investigators. Results Through data analysis and alignment with literature in DOI theory in health care practice, the factors that determine innovation adoption were verified. The phenomena of implementation in PT practice are largely consistent with models of implementation in health care service. Within the outpatient practices studied, patient-centered care and collaborative learning were foundational elements to diffusion of an innovation. Conclusion Innovation in outpatient physical therapy practice can be understood as a social process situated within the culture of the physical therapy professional that follows predictable patterns that strongly align with DOI theory and the CFIR.

This study examined how characteristics of practice leadership affect the change process in a statewide initiative to improve the quality of diabetes and asthma care. We used a mixed methods approach, involving analyses of existing quality improvement data on 76 practices with at least 1 year of participation and focus groups with clinicians and staff in a 12-practice subsample. Existing data included monthly diabetes or asthma measures (clinical measures) and monthly practice implementation, leadership, and practice engagement scores rated by an external practice coach. Of the 76 practices, 51 focused on diabetes and 25 on asthma. In aggregate, 50% to 78% made improvements within in each clinical measure in the first year. The odds of making practice changes were greater for practices with higher leadership scores (odds ratios = 2.41-4.20). Among practices focused on diabetes, those with higher leadership scores had higher odds of performing nephropathy screening (odds ratio = 1.37, 95% CI, 1.08-1.74); no significant associations were seen for the intermediate outcome measures of hemoglobin A1c, blood pressure, and cholesterol. Focus groups revealed the importance of a leader, typically a physician, who believed in the transformation work (ie, a visionary leader) and promoted practice engagement through education and cross-training. Practices with greater change implementation also mentioned the importance of a midlevel operational leader who helped to create and sustain practice changes. This person communicated and interacted well with, and was respected by both clinicians and staff. In the presence of a vision for transformation, operational leaders within practices can facilitate practice changes that are associated with clinical improvement.

The objective of the study described is to assess the feasibility and effectiveness of using a criterion-based clinical audit to measure and improve the quality of obstetric care at the district hospital level in developing countries. The focus is on the management of five life-threatening obstetric complications--hemorrhage, eclampsia, genital tract infection, obstructed labor and uterine rupture was audited using a "before and after" design. The five steps of the audit cycle were followed: establish criteria of good quality care; measure current practice (Review I); feedback findings and set targets; take action to change practice; and re-evaluate practice (Review II). Systematic literature review, panel discussions and pilot work led to the development of 31 audit criteria. Review I included 555 life-threatening complications occurring over 66 hospital-months; Review II included 342 complications over 42 hospital-months. Many common areas for improvement were identified across the four hospitals. Agreed mechanisms for achieving these improvements included clinical protocols, reviews of staffing, and training workshops. Some aspects of clinical monitoring, drug use and record keeping improved significantly between Reviews I and II. Criterion-based clinical audit in four typical district hospitals in Ghana and Jamaica is a feasible and acceptable method for quality assurance and appears to have improved the management of life-threatening obstetric complications.

Guo, Shijun; Lyu, Jie; Zhang, Peiming

2017-08-01

In this paper, the teaching goals, teaching contents and teaching methods in biomedical optics course construction are discussed. From the dimension of teaching goals, students should master the principle of optical inspection on the human body, diagnosis and treatment of methodology and instruments, through the study of the theory and practice of this course, and can utilize biomedical optics methods to solve practical problems in the clinical medical engineering practice. From the dimension of teaching contents, based on the characteristics of biomedical engineering in medical colleges, the organic integration of engineering aspects, medical optical instruments, and biomedical aspects dispersed in human anatomy, human physiology, clinical medicine fundamental related to the biomedical optics is build. Noninvasive measurement of the human body composition and noninvasive optical imaging of the human body were taken as actual problems in biomedical optics fields. Typical medical applications such as eye optics and laser medicine were also integrated into the theory and practice teaching. From the dimension of teaching methods, referencing to organ-system based medical teaching mode, optical principle and instrument principle were taught by teachers from school of medical instruments, and the histological characteristics and clinical actual need in areas such as digestive diseases and urinary surgery were taught by teachers from school of basic medicine or clinical medicine of medical colleges. Furthermore, clinical application guidance would be provided by physician and surgeons in hospitals.

In Latin America, sexual role, sexual identity and sexual practices are intricately related; the roles activo, pasivo and moderno often encompass sexual identity and sexual practices. We aimed to understand the association between sexual role and HIV status in Peruvian men who have sex with men. HIV-testing services at Epicentro Salud, a Peruvian gay men's health centre, were paired with clinic data on demographics and sexual behaviour. Bidirectional stepwise logistic regression was conducted to determine associations between sexual role and HIV status. Of 366 clients who underwent HIV testing, 86 (23.5%) tested positive. There was a strong association between sexual role ('activo' or typically insertive, 'pasivo' or typically receptive, 'moderno' or typically versatile) and a positive HIV test (p = 0.002). Compared to clients with an activo role, those who reported a pasivo (OR = 6.14) and moderno (OR = 6.26) role were more likely to test positive for HIV. Sexual role was associated with sexual identity (gay, straight and bisexual) and gender of partners in the past six months. Self-reported pasivo and moderno sexual roles were strongly associated with a positive HIV test result. Further research should examine differences in sexual practices between sexual role groups. © The Author(s) 2016.

To foster nursing professionals, nursing education requires the integration of knowledge and practice. Nursing students in their senior year experience considerable stress in performing the core nursing skills because, typically, they have limited opportunities to practice these skills in their clinical practicum. Therefore, nurse educators should revise the nursing curricula to focus on core nursing skills. To identify the effect of an intensive clinical skills course for senior nursing students on their self-confidence and clinical competence. A quasi-experimental post-test study. A university in South Korea during the 2015-2016 academic year. A convenience sample of 162 senior nursing students. The experimental group (n=79) underwent the intensive clinical skills course, whereas the control group (n=83) did not. During the course, students repeatedly practiced the 20 items that make up the core basic nursing skills using clinical scenarios. Participants' self-confidence in the core clinical nursing skills was measured using a 10-point scale, while their clinical competence with these skills was measured using the core clinical nursing skills checklist. Independent t-test and chi-square tests were used to analyze the data. The mean scores in self-confidence and clinical competence were higher in the experimental group than in the control group. This intensive clinical skills courses had a positive effect on senior nursing students' self-confidence and clinical competence for the core clinical nursing skills. This study emphasizes the importance of reeducation using a clinical skills course during the transition from student to nursing professional. Copyright © 2017. Published by Elsevier Ltd.

Atopic dermatitis (AD) is a disease characterized by relapsing eczema with pruritus as a primary lesion. Most patients have an atopic predisposition. The definitive diagnosis of AD requires the presence of all three features: (i) pruritus; (ii) typical morphology and distribution of the eczema; and (iii) chronic and chronically relapsing course. The current strategies to treat AD in Japan from the perspective of evidence-based medicine consist of three primary measures: (i) the use of topical corticosteroids and tacrolimus ointment as the main treatment for the inflammation; (ii) topical application of emollients to treat the cutaneous barrier dysfunction; and (iii) avoidance of apparent exacerbating factors, psychological counseling and advice about daily life. The guidelines present recommendations to review clinical research articles, evaluate the balance between the advantages and disadvantages of medical activities, and optimize medical activity-related patient outcomes with respect to several important points requiring decision-making in clinical practice. © 2016 Japanese Dermatological Association.

Intramuscular preparations of antipsychotics: uses and relevance in clinical practice.

Intramuscular formulations of antipsychotics can be sub-divided into two groups on the basis of their pharmacokinetic features: short-acting preparations and long-acting or depot preparations. Short-acting intramuscular formulations are used to manage acute psychotic episodes. On the other hand, long-acting compounds, also called "depot", are administered as antipsychotic maintenance treatment to ensure compliance and to eliminate bioavailability problems related to absorption and first pass metabolism. Adverse effects of antipsychotics have been studied with particular respect to oral versus short- and long-acting intramuscular formulations of the different compounds. For short-term intramuscular preparations the main risk with classical compounds are hypotension and extrapyramidal side effects (EPS). Data on the incidence of EPS with depot formulations are controversial: some studies point out that the incidence of EPS is significantly higher in patients receiving depot preparations, whereas others show no difference between oral and depot antipsychotics. Studies on the strategies for switching patients from oral to depot treatment suggest that this procedure is reasonably well tolerated, so that in clinical practice depot antipsychotic therapy is usually begun while the oral treatment is still being administered, with gradual tapering of the oral dose. Efficacy, pharmacodynamics and clinical pharmacokinetics of haloperidol decanoate, fluphenazine enanthate and decanoate, clopenthixol decanoate, zuclopenthixol decanoate and acutard, flupenthixol decanoate, perphenazine enanthate, pipothiazine palmitate and undecylenate, and fluspirilene are reviewed. In addition, the intramuscular preparations of atypical antipsychotics and clinical uses are reviewed. Olanzapine and ziprasidone are available only as short-acting preparations, while risperidone is to date the only novel antipsychotic available as depot formulation. To date, acutely ill, agitated psychotic patients have been treated with high parenteral doses of typical antipsychotics, which often cause serious EPS, especially dystonic reactions. Intramuscular formulations of novel antipsychotics (olanzapine and ziprasidone), which appear to have a better tolerability profile than typical compounds, showed an equivalent efficacy to parenteral typical agents in the acute treatment of psychoses. However, parenteral or depot formulations of atypical antipsychotics are not yet widely available.

Custom software development for use in a clinical laboratory

2012-01-01

In-house software development for use in a clinical laboratory is a controversial issue. Many of the objections raised are based on outdated software development practices, an exaggeration of the risks involved, and an underestimation of the benefits that can be realized. Buy versus build analyses typically do not consider total costs of ownership, and unfortunately decisions are often made by people who are not directly affected by the workflow obstacles or benefits that result from those decisions. We have been developing custom software for clinical use for over a decade, and this article presents our perspective on this practice. A complete analysis of the decision to develop or purchase must ultimately examine how the end result will mesh with the departmental workflow, and custom-developed solutions typically can have the greater positive impact on efficiency and productivity, substantially altering the decision balance sheet. Involving the end-users in preparation of the functional specifications is crucial to the success of the process. A large development team is not needed, and even a single programmer can develop significant solutions. Many of the risks associated with custom development can be mitigated by a well-structured development process, use of open-source tools, and embracing an agile development philosophy. In-house solutions have the significant advantage of being adaptable to changing departmental needs, contributing to efficient and higher quality patient care. PMID:23372985

Aneurysmal bone cysts are rare entities which causes expansile and destructive bone lesions characterized by reactive proliferation of connective tissue. They usually grow rapidly with hypervascularity. In clinical practice they can be easily misdiagnosed due to the rare occurance and having no such typical findings as radiologically. Most cases have uncommon pain symptoms, but rarely, if fractures occur, neurological findings can be seen and the surgical treatment, if needed, could be difficult. We will discuss our evaluations to two cases that we experienced in our clinic in this report. PMID:25620988

2014-01-01

A survey of 231 Australian speech-language pathologists (SLPs) was undertaken to describe practices regarding assessment, analysis, target selection, intervention, and service delivery for children with speech sound disorders (SSD). The participants typically worked in private practice, education, or community health settings and 67.6% had a waiting list for services. For each child, most of the SLPs spent 10-40 min in pre-assessment activities, 30-60 min undertaking face-to-face assessments, and 30-60 min completing paperwork after assessments. During an assessment SLPs typically conducted a parent interview, single-word speech sampling, collected a connected speech sample, and used informal tests. They also determined children's stimulability and estimated intelligibility. With multilingual children, informal assessment procedures and English-only tests were commonly used and SLPs relied on family members or interpreters to assist. Common analysis techniques included determination of phonological processes, substitutions-omissions-distortions-additions (SODA), and phonetic inventory. Participants placed high priority on selecting target sounds that were stimulable, early developing, and in error across all word positions and 60.3% felt very confident or confident selecting an appropriate intervention approach. Eight intervention approaches were frequently used: auditory discrimination, minimal pairs, cued articulation, phonological awareness, traditional articulation therapy, auditory bombardment, Nuffield Centre Dyspraxia Programme, and core vocabulary. Children typically received individual therapy with an SLP in a clinic setting. Parents often observed and participated in sessions and SLPs typically included siblings and grandparents in intervention sessions. Parent training and home programs were more frequently used than the group therapy. Two-thirds kept up-to-date by reading journal articles monthly or every 6 months. There were many similarities with previously reported practices for children with SSD in the US, UK, and the Netherlands, with some (but not all) practices aligning with current research evidence.

Vitamin D is of paramount importance to skeletal development, integrity and health. Vitamin D homeostatis is typically deranged in a number of chronic conditions, of which chronic kidney disease is one of the most important. The use of vitamin D based therapy to target secondary hyperparathyroidism is now several decades old, and there is a large body of clinical practice, experience, guidelines and research to underpin this. However, there are many unknowns, of significant clinical relevance. Amongst which is what "species" of vitamin D we should be using, in what patient, and, under what conditions. Sadly, there has been a real dearth of randomised controlled trials, and trials with outputs of clinical relevance, which means our clinical practice has not developed and refined adequately ove the last 4 decades. This article will discuss the vexed but critical questions of which vitamin D therapies might suit which kidney patients, and will high-light the many important clinical questions which urgently require answering.

Newman, Eric D; Lerch, Virginia; Jones, J B; Stewart, Walter

2012-04-01

While questionnaires have been developed to capture patient-reported outcomes (PROs) in rheumatology practice, these instruments are not widely used. We developed a touchscreen interface designed to provide reliable and efficient data collection. Using the touchscreen to obtain PROs, we compared 2 different workflow models implemented separately in 2 rheumatology clinics. The Plan-Do-Study-Act methodology was used in 2 cycles of workflow redesign. Cycle 1 relied on off-the-shelf questionnaire builder software, and cycle 2 relied on a custom programmed software solution. During cycle 1, clinic 1 (private practice model, resource replete, simple flow) demonstrated a high completion rate at the start, averaging between 74% and 92% for the first 12 weeks. Clinic 2 (academic model, resource deficient, complex flow) did not achieve a consistent completion rate above 60%. The revised cycle 2 implementation protocol incorporated a 15-minute "nurse visit," an instant messaging system, and a streamlined authentication process, all of which contributed to substantial improvement in touchscreen questionnaire completion rates of ∼80% that were sustained without the need for any additional clinic staff support. Process redesign techniques and touchscreen technology were used to develop a highly successful, efficient, and effective process for the routine collection of PROs in a busy, complex, and resource-depleted academic practice and in typical private practice. The successful implementation required both a touchscreen questionnaire, human behavioral redesign, and other technical solutions. Copyright © 2012 by the American College of Rheumatology.

The Length of Child Anxiety Treatment in a Regional Health System.

2016-12-01

Anxiety disorders are often undertreated due to unsuccessful dissemination of evidence-based treatments (EBTs). Lack of empirical data regarding the typical length of treatment in clinical settings may hamper the development of clinically relevant protocols. The current study examined billing records for 335 children ages 7-17 years to quantify the treatment received for newly diagnosed anxiety disorders within a regional health system. The vast majority of patients did not receive a sufficient number of appointments to complete the typical cognitive behavioral therapy protocol or reach the sessions introducing exposure. Although half of the sample received pharmacotherapy, the vast majority received fewer follow-up appointments than participants in pharmacotherapy research studies. Further, the type of treatment (i.e., number of sessions and medication) differed depending on utilization of specialty care. These results underscore the need to develop brief and flexible EBT protocols that can be standardized and implemented in community practice.

To describe the nature and scope of nurse-midwifery practice in Texas and to determine legislative priorities and practice barriers. Across the globe, midwives are the largest group of maternity care providers despite little known about midwifery practice. With a looming shortage of midwives, there is a pressing need to understand midwives' work environment and scope of practice. Mixed methods research utilizing prospective descriptive survey and interview. An online survey was administered to nurse-midwives practicing in the state of Texas (N=449) with a subset (n=10) telephone interviewed. Descriptive and inferential statistics and content analysis was performed. The survey was completed by 141 midwives with 8 interviewed. Most were older, Caucasian, and held a master's degree. A majority worked full-time, were in clinical practice in larger urban areas, and were employed by a hospital or physician-group. Care was most commonly provided for Hispanic and white women; approximately a quarter could care for greater numbers of patients. Most did not clinically teach midwifery students. Physician practice agreements were believed unnecessary and prescriptive authority requirements restrictive. Legislative issues were typically followed through the professional organization or social media sites; most felt a lack of competence to influence health policy decisions. While most were satisfied with current clinical practice, a majority planned a change in the next 3 to 5 years. An aging midwifery workforce, not representative of the race/ethnicity of the populations served, is underutilized with practice requirements that limit provision of services. Health policy changes are needed to ensure unrestricted practice. This article is protected by copyright. All rights reserved. This article is protected by copyright. All rights reserved.

Smorgick, Noam; Maymon, Ron

2014-01-01

Pelvic ultrasound is commonly used as part of the routine gynecologic exams, resulting in diagnosis of adnexal masses, the majority of which are functional or benign. However, due to the possible complications involving benign adnexal cysts (ie, adnexal torsion, pelvic pain) and the utmost importance of early diagnosis and treatment of ovarian cancer, the correct ultrasound diagnosis of adnexal masses is essential in clinical practice. This review will describe the typical ultrasound appearance of the common physiologic, benign, and malignant adnexal masses with the aim of aiding the clinician to reach the correct diagnosis.

Changes in patterns of living result in changes in the nature and causes of disease. The industrial revolution of the late 18th century, and the technological revolution of the late 20th century are cases in point. The former was associated with a decline in infectious diseases; the latter with an increase in lifestyle and environmentally induced chronic diseases . Health practices are typically modified to deal with such changes, hence the recent rise in interest in lifestyle-oriented forms of clinical practice. © 2014 John Wiley & Sons Ltd.

Clinical neuropsychology practice and training in Canada.

PubMed

Janzen, Laura A; Guger, Sharon

2016-11-01

This invited paper provides information about professional neuropsychology issues in Canada and is part of a special issue addressing international perspectives on education, training, and practice in clinical neuropsychology. Information was gathered from literature searches and personal communication with other neuropsychologists in Canada. Canada has a rich neuropsychological history. Neuropsychologists typically have doctoral-level education including relevant coursework and supervised practical experience. Licensure requirements vary across the 10 provinces and there are regional differences in salary. While training at the graduate and internship level mirrors that of our American colleagues, completion of a two-year postdoctoral fellowship in neuropsychology is not required to obtain employment in many settings and there are few postdoctoral training programs in this country. The majority of neuropsychologists are employed in institutional settings (e.g. hospitals, universities, rehabilitation facilities), with a growing number entering private practice or other settings. There are challenges in providing neuropsychological services to the diverse Canadian population and a need for assessment measures and normative data in multiple languages. Canadian neuropsychologists face important challenges in defining ourselves as distinct from other professions and other psychologists, in maintaining funding for high-quality training and research, in establishing neuropsychology-specific training and practice standards at the provincial or national level, and ensuring the clinical care that we provide is efficient and effective in meeting the needs of our patient populations and consumers, both within and outside of the publically funded health care system.

The 'sense of alarm' ('gut feeling') in clinical practice. A survey among European general practitioners on recognition and expression.

Most general practitioners in the Netherlands and Flanders (Belgium) are familiar with that special feeling during certain consultations: 'There's something wrong here, though I have no specific indications yet'. This 'sense of alarm' alerts the doctor, activates the diagnostic process and induces him to initiate specific management to prevent serious health problems. We wanted to know whether this sense of alarm is a typical phenomenon among Dutch-speaking GPs or is also recognized by GPs elsewhere in Europe. A short questionnaire survey was held among 128 GPs in 28 countries included in the European General Practitioners Research Network (EGPRN). GPs were asked if they recognized our description of the 'sense of alarm' and if they used a typical phrase in their language to express this uneasy feeling. We received 30 replies from GPs in 16 European countries, plus Israel and South-Africa. They all recognized our description and 25 GPs reported typical expressions in their own language. The GPs' uneasy feeling was sometimes perceived as a bodily sensation. The 'sense of alarm' is a familiar phenomenon in general practices in Europe. We propose to use the English phrase 'gut feelings' in further research reports.

Existing text-based clinical practice guidelines can be difficult to put into practice. While a growing number of such documents have gained acceptance in the medical community and contain a wealth of valuable information, the time required to digest them is substantial. Yet the expressive power, subtlety and flexibility of natural language pose challenges when designing computer tools that will help in their application. At the same time, formal computer languages typically lack such expressiveness and the effort required to translate existing documents into these languages may be costly. We propose a method based on the mark-up concept for converting text-based clinical guidelines into a machine-operable form. This allows existing guidelines to be manipulated by machine, and viewed in different formats at various levels of detail according to the needs of the practitioner, while preserving their originally published form.

Why nursing has not embraced the clinician--scientist role.

PubMed

Mackay, Martha

2009-10-01

Reasons for the limited uptake of the clinician-scientist role within nursing are examined, specifically: the lack of consensus about the nature of nursing science; the varying approaches to epistemology; and the influence of post-modern thought on knowledge development in nursing. It is suggested that under-development of this role may be remedied by achieving agreement that science is a necessary, worthy pursuit for nursing, and that rigorous science conducted from a clinical perspective serves nursing well. Straddling practice and research is a powerful strategy for ensuring relevant research while forging strong links with practice. The clinician-scientist role, typically requiring a 75:25 ratio between research and clinical activities, is well established in medicine. Nursing, however, has been slow to institute the role; it is rare within North America, Australia, and western European countries, and almost non-existent outside those areas. Beyond structural obstacles, philosophical issues may explain nursing's reluctance to implement the role. Following a survey of clinician-scientist roles throughout the world, the nature of nursing science and epistemology, and the influence of post-modern thought on nursing attitudes to research are examined with respect to their influence on this role. The nurse clinician-scientist role holds promise for making strides in clinically relevant research, and for accelerating the knowledge cycle from clinical problem to research question to change in clinical practice.

[Philosophy of psychiatry and phenomenology of everyday life: The disruptions of ordinary experience in schizophrenia].

PubMed

Troubé, Sarah

2016-12-01

The paper considers the philosophy of psychiatry from the perspective of everyday life, as a particular structure of experience. We outline some questions raised by disturbances typical of psychotic disorders with regard to a phenomenology of the everyday and common sense. As a link between philosophy and clinical psychopathology, this phenomenology implies a transcendental point of view, embedded in concrete and practical forms of ordinary experience, along with social norms. This opens the possibility of a mutual questioning between philosophy and psychiatry, drawing on its clinical, epistemological, and ethical dimensions.

Anorexia nervosa is a potentially life-threatening disorder with a typical onset in adolescence and high rates of medical complications and psychiatric comorbidity. This article summarizes issues relating to classification in DSM-5 and presents a narrative review of key evidence-based medical and behavioral interventions for adolescent AN and subthreshold restricting eating disorders, mainly, but not exclusively published between 2012 and 2014. In addition, it systematically compares the clinical guidelines of four European countries (Germany, Spain, The Netherlands, and United Kingdom) and outlines common clinical practice, in relation to treatment settings, nutritional rehabilitation, family-oriented and individual psychotherapy, and psychopharmacological treatment. With the exception of family-based treatment, which is mainly evaluated and practiced in Anglo-American countries, the evidence base is weak, especially for medical interventions such as refeeding and pharmacological intervention. There is a need for common European research efforts, to improve the available evidence base and resulting clinical guidance.

Do motives matter in male circumcision? 'Conscientious objection' against the circumcision of a Muslim child with a blood disorder.

PubMed

Ahmad, Ayesha

2014-02-01

Whilst there have been serious attempts to locate the practice of male circumcision for religious motives in the context of the (respective) religion's narrative and community, the debate, when referring to a clinical context, is often more nuanced. This article will contribute further to the debate by contextualising the Islamic practice of male circumcision within the clinical setting typical of a contemporary hospital. It specifically develops an additional complication; namely, the child has a pre-existing blood disorder. As an approach to contributing to the circumcision debate further, the ethics of a conscientious objection for secular motives towards a religiously-motivated clinical intervention will be explored. Overall, the discussion will provide relevance for such debates within the value-systems of a multi-cultural society. This article replicates several approaches to deconstructing a request for conscientious refusal of non-therapeutic circumcision by a Clinical Ethics Committee (CEC), bringing to light certain contradictions that occur in normatively categorizing motives for performing the circumcision. © 2013 John Wiley & Sons Ltd.

Immunonutrition in septic patients: a philosophical view of the current situation.

PubMed

Bertolini, Guido; Luciani, Davide; Biolo, Gianni

2007-02-01

Two different ways of thinking pervaded the history of science: rationalism and empiricism. In theory, these two paradigms are not necessarily in conflict. In practice, there has always been tension between them. The coming of evidence-based medicine put empiricism in a privileged position, but empiricism without a rationalistic guide could even be usefulness. The aim of this work is to present the tension between the rational reasons to administer immunonutrients to patients with sepsis and the controversial empirical evidence stemming from clinical trials. We reviewed the literature on immunonutrition in sepsis from the rationalist and the empiricist perspectives. The large body of evidence for positive effects of immunonutrients in experimental models and the contradictory results from clinical trials make the discussion on immunonutrition in sepsis a typical example where the conflict between rationalism and empiricism hampered the advancement of knowledge and the implementation of new effective therapies into clinical practice. Future research projects involving immunonutrients should be based on robust knowledge of basic mechanisms of action to be properly addressed in clinical trials.

The University of Colorado Denver School of Dental Medicine has operated a community-based dental education program for all of its students since 1985. A database of student productivity has been maintained in a standardized format, capable of multiyear compilation, since 1994. This study utilizes twelve years of these data to profile the type and amount of clinical treatment that can be provided by a typical fourth-year dental student during a 100-day community-based training experience. Between 1994 and 2006, the school's 423 graduates provided a mean of 922 treatment procedures per student at a mean of 498 patient visits per student. During a typical four-week clinical affiliation, each student provided a mean of approximately twenty-seven restorations on permanent teeth, sixteen restorations on primary teeth, and twenty-four oral surgery procedures (extractions). Students also gained considerable experience in periodontics, fixed and removable prosthodontics, and endodontics. Self-assessed competency ratings tended to increase after completing the program, as did willingness to treat underserved populations after graduation. About 16 percent of graduates reported planning to practice in the public sector after completing dental school. A community-based experience such as this appears to offer an opportunity to substantially augment dental students' clinical training experiences.

The number of Natural Language Processing (NLP) tools and systems for processing clinical free-text has grown as interest and processing capability have surged. Unfortunately any two systems typically cannot simply interoperate, even when both are built upon a framework designed to facilitate the creation of pluggable components. We present two ongoing activities promoting open source clinical NLP. The Open Health Natural Language Processing (OHNLP) Consortium was originally founded to foster a collaborative community around clinical NLP, releasing UIMA-based open source software. OHNLP's mission currently includes maintaining a catalog of clinical NLP software and providing interfaces to simplify the interaction of NLP systems. Meanwhile, Apache cTAKES aims to integrate best-of-breed annotators, providing a world-class NLP system for accessing clinical information within free-text. These two activities are complementary. OHNLP promotes open source clinical NLP activities in the research community and Apache cTAKES bridges research to the health information technology (HIT) practice.

The role of acute care nurse practitioners (ACNPs) in trauma care has evolved over time. A survey was performed with the aim of describing the role across the United States. There were 68 respondents who depicted the typical trauma ACNP as being a 42-year-old woman who works full-time at a level I American College of Surgeons verified trauma center. Trauma ACNPs typically practice with 80% of their time for clinical care and are based on a trauma and acute care surgery service. They are acute care certified and hold several advanced certifications to supplement their nursing license.

Understanding barriers to evidence-based assessment: Clinician attitudes toward standardized assessment tools

Jensen-Doss, Amanda; Hawley, Kristin M.

2010-01-01

In an era of evidence-based practice, why are clinicians not typically engaged in evidence-based assessment? To begin to understand this issue, a national multidisciplinary survey was conducted to examine clinician attitudes toward standardized assessment tools. 1442 child clinicians provided opinions about the psychometric qualities of these tools, their benefit over clinical judgment alone, and their practicality. Doctoral-level clinicians and psychologists expressed more positive ratings in all three domains than master’s-level clinicians and non-psychologists respectively, although only the disciplinary differences remained significant when predictors were examined simultaneously. All three attitude scales were predictive of standardized assessment tool use, although practical concerns were the strongest and only independent predictor of use. PMID:21058134

Procurement of Human Tissues for Research Banking in the Surgical Pathology Laboratory: Prioritization Practices at Washington University Medical Center

Academic hospitals and medical schools with research tissue repositories often derive many of their internal human specimen acquisitions from their site's surgical pathology service. Typically, such acquisitions come from appropriately consented tissue discards sampled from surgical resections. Because the practice of surgical pathology has patient care as its primary mission, competing needs for tissue inevitably arise, with the requirement to preserve adequate tissue for clinical diagnosis being paramount. A set of best-practice gross pathology guidelines are summarized here, focused on the decision for tissue banking at the time specimens are macroscopically evaluated. These reflect our collective experience at Washington University School of Medicine, and are written from the point of view of our site biorepository. The involvement of trained pathology personnel in such procurements is very important. These guidelines reflect both good surgical pathology practice (including the pathologic features characteristic of various anatomic sites) and the typical objectives of research biorepositories. The guidelines should be helpful to tissue bank directors, and others charged with the procurement of tissues for general research purposes. We believe that appreciation of these principles will facilitate the partnership between surgical pathologists and biorepository directors, and promote both good patient care and strategic, value-added banking procurements.

Global Collaboration in Acute Care Clinical Research: Opportunities, Challenges, and Needs.

Marshall, John C

2017-02-01

The most impactful research in critical care comes from trials groups led by clinician-investigators who study questions arising through the day-to-day care of critically ill patients. The success of this model reflects both "necessity"-the paucity of new therapies introduced through industry-led research-and "clinical reality"-nuanced modulation of standard practice can have substantial impact on clinically important outcomes. Success in a few countries has fueled efforts to build similar models around the world and to collaborate on an unprecedented scale in large international trials. International collaboration brings opportunity-the more rapid completion of clinical trials, enhanced generalizability of the results of these trials, and a focus on questions that have evoked international curiosity. It has changed practice, improved outcomes, and enabled an international response to pandemic threats. It also brings challenges. Investigators may feel threatened by the loss of autonomy inherent in collaboration, and appropriate models of academic credit are yet to be developed. Differences in culture, practice, ethical frameworks, research experience, and resource availability create additional imbalances. Patient and family engagement in research is variable and typically inadequate. Funders are poorly equipped to evaluate and fund international collaborative efforts. Yet despite or perhaps because of these challenges, the discipline of critical care is leading the world in crafting new models of clinical research collaboration that hold the promise of not only improving the care of the most vulnerable patients in the healthcare system but also transforming the way that we conduct clinical research.

The Development of English as a Second Language With and Without Specific Language Impairment: Clinical Implications.

PubMed

Paradis, Johanne

2016-02-01

The purpose of this research forum article is to provide an overview of typical and atypical development of English as a second language (L2) and to present strategies for clinical assessment with English language learners (ELLs). A review of studies examining the lexical, morphological, narrative, and verbal memory abilities of ELLs is organized around 3 topics: timeframe and characteristics of typical English L2 development, comparison of the English L2 development of children with and without specific language impairment (SLI), and strategies for more effective assessment with ELLs. ELLs take longer than 3 years to converge on monolingual norms and approach monolingual norms asynchronously across linguistic subdomains. Individual variation is predicted by age, first language, language learning aptitude, length of exposure to English in school, maternal education, and richness of the English environment outside school. ELLs with SLI acquire English more slowly than ELLs with typical development; their morphological and nonword repetition abilities differentiate them the most. Use of strategies such as parent questionnaires on first language development and ELL norm referencing can result in accurate discrimination of ELLs with SLI. Variability in the language abilities of ELLs presents challenges for clinical practice. Increased knowledge of English language learning development with and without SLI together with evidence-based alternative assessment strategies can assist in overcoming these challenges.

The aims of this study were (1) to develop centile reference values for anaerobic performance of Dutch children tested using the Muscle Power Sprint Test (MPST) and (2) to examine the test-retest reliability of the MPST. Children who were developing typically (178 boys and 201 girls) and aged 6 to 12 years (mean = 8.9 years) were recruited. The MPST was administered to 379 children, and test-retest reliability was examined in 47 children. MPST scores were transformed into centile curves, which were created using generalized additive models for location, scale, and shape. Height-related reference curves were created for both genders. Excellent (intraclass correlation coefficient = 0.98) test-retest reliability was demonstrated. The reference values for the MPST of children who are developing typically and aged 6 to 12 years can serve as a clinical standard in pediatric physical therapy practice. The MPST is a reliable and practical method for determining anaerobic performance in children.

Clinical implications of contemporary gender theory.

PubMed

Kulish, Nancy

2010-04-01

The current intellectual scene in psychoanalysis is marked by vigorous theoretical controversies about gender. The ideas being debated have important implications for clinical work, which have not been thoroughly explicated or integrated into common practice. These implications include the following: gender can accrue idiosyncratic meanings; gender identity is considered fluid and rigidity of gender identity deemed problematic; gender-related conflicts are typically described as divergent; analysis of superego conflicts related to gender becomes particularly important; and, finally, gender-related biases are seen as inevitable and must be taken into account in the clinical situation. A detailed clinical example illustrates the application of these ideas. While the more dramatic cases related to gender have been more frequent subjects of study, conflicts about gender are everyday occurrences for our patients and deserve further attention.

A cornerstone of the recent consensus statements on concussion is a multifaceted concussion-assessment program at baseline and postinjury and when tracking recovery. Earlier studies of athletic trainers' (ATs') practice patterns found limited use of multifaceted protocols; however, these authors typically grouped diverse athletic training settings together. To (1) describe the concussion-management practice patterns of National Collegiate Athletic Association (NCAA) Division I ATs, (2) compare these practice patterns to earlier studies, and (3) objectively characterize the clinical examination. Cross-sectional study. Online survey. A total of 610 ATs from NCAA Division I institutions, for a response rate of 34.4%. The survey had 3 subsections: demographic questions related to the participant's experiences, concussion-assessment practice patterns, and concussion-recovery and return-to-participation practice patterns. Specific practice-pattern questions addressed balance, cognitive and mental status, neuropsychological testing, and self-reported symptoms. Finally, specific components of the clinical examination were examined. We identified high rates of multifaceted assessments (i.e., assessments using at least 3 techniques) during testing at baseline (71.2%), acute concussion assessment (79.2%), and return to participation (66.9%). The specific techniques used are provided along with their adherence with evidence-based practice findings. Respondents endorsed a diverse array of clinical examination techniques that often overlapped objective concussion-assessment protocols or were likely used to rule out associated potential conditions. Respondents were cognizant of the Third International Consensus Statement, the National Athletic Trainers' Association position statement, and the revised NCAA Sports Medicine Handbook recommendations. Athletic trainers in NCAA Division I demonstrated widespread use of multifaceted concussion-assessment techniques and appeared compliant with recent consensus statements and the NCAA Sports Medicine Handbook.

The goal of this study was to document current clinical practice and report patient outcomes in presurgical language functional MRI (fMRI) for epilepsy surgery. Epilepsy surgical programs worldwide were surveyed as to the utility, implementation, and efficacy of language fMRI in the clinic; 82 programs responded. Respondents were predominantly US (61%) academic programs (85%), and evaluated adults (44%), adults and children (40%), or children only (16%). Nearly all (96%) reported using language fMRI. Surprisingly, fMRI is used to guide surgical margins (44% of programs) as well as lateralize language (100%). Sites using fMRI for localization most often use a distance margin around activation of 10mm. While considered useful, 56% of programs reported at least one instance of disagreement with other measures. Direct brain stimulation typically confirmed fMRI findings (74%) when guiding margins, but instances of unpredicted decline were reported by 17% of programs and 54% reported unexpected preservation of function. Programs reporting unexpected decline did not clearly differ from those which did not. Clinicians using fMRI to guide surgical margins do not typically map known language-critical areas beyond Broca's and Wernicke's. This initial data shows many clinical teams are confident using fMRI not only for language lateralization but also to guide surgical margins. Reported cases of unexpected language preservation when fMRI activation is resected, and cases of language decline when it is not, emphasize a critical need for further validation. Comprehensive studies comparing commonly-used fMRI paradigms to predict stimulation mapping and post-surgical language decline remain of high importance. © 2018 The Authors Human Brain Mapping Published by Wiley Periodicals, Inc.

The present study sought to quantify the generalizability of pharmacologic and psychotherapy clinical trial results in individuals with a DSM-IV diagnosis of posttraumatic stress disorder (PTSD) to a large representative community sample. Data were derived from the 2004-2005 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a large nationally representative sample of the adult US population. We applied a standard set of exclusion criteria representative of pharmacologic and psychotherapy clinical trials to all adults with a DSM-IV diagnosis of PTSD in the previous 12 months (n = 1,715) and then to a subsample of participants seeking treatment (n = 366). Our aim was to assess how many participants with PTSD would fulfill typical eligibility criteria. We found that more than 6 of 10 respondents from the overall PTSD sample and more than 7 of 10 respondents seeking treatment for PTSD would have been excluded by 1 exclusion criterion or more in a typical pharmacologic trial. In contrast, about 2 of 10 participants in the full sample and about 3 of 10 participants seeking treatment for PTSD would have been excluded in a typical psychotherapy efficacy trial. We found that psychotherapy trial results may be applied to most patients with PTSD in routine clinical practice. The designers of pharmacologic clinical trials should carefully consider the trade-offs between the application of each exclusion criterion and its impact on representativeness. Specification a priori of the goals of the study, better justification for each exclusion criterion, and estimation of the proportion of individuals ineligible for the trial would assist study design. Developing integrated forms of pharmacotherapy and psychotherapy that simultaneously target commonly overlapping psychiatric disorders may yield more informative results for mental health care providers and research funding agencies. © Copyright 2016 Physicians Postgraduate Press, Inc.

Knowledge translation is an essential and emerging arena in healthcare research. It is the process of aiding the application of research knowledge into clinical practice or policymaking. Individuals at all levels of the health care system, including patients, healthcare professionals, and policymakers, are affected by the gaps that exist between research evidence and practice; the process of knowledge translation plays a role in bridging these gaps and incorporating high-quality clinical research into decision-making. Cardiovascular disease (CVD) management is a crucial area of healthcare where information gaps are known to exist. Although Japan has one of the lowest risks and mortality rates from CVDs, an increasing trend of cardiovascular incidence and changes in the risk factor conditions have been observed in recent years. This article provides an overview of knowledge translation and its importance in the cardiovascular health of the Japanese population, and describes the key steps of a typical knowledge translation strategy.

An important issue in the debate about terminal sedation is the extent to which it differs from euthanasia. We studied clinical differences and similarities between both practices in the Netherlands. Personal interviews were held with a nationwide stratified sample of 410 physicians (response rate, 85%) about the most recent cases in which they used terminal sedation, defined as administering drugs to keep the patient continuously in deep sedation or coma until death without giving artificial nutrition or hydration (n = 211), or performed euthanasia, defined as administering a lethal drug at the request of a patient with the explicit intention to hasten death (n = 123). We compared characteristics of the patients, the decision-making process, and medical care of both practices. Terminal sedation and euthanasia both mostly concerned patients with cancer. Patients receiving terminal sedation were more often anxious (37%) and confused (24%) than patients receiving euthanasia (15% and 2%, respectively). Euthanasia requests were typically related to loss of dignity and a sense of suffering without improving, whereas requesting terminal sedation was more often related to severe pain. Physicians applying terminal sedation estimated that the patient's life had been shortened by more than 1 week in 27% of cases, compared with 73% in euthanasia cases. Terminal sedation and euthanasia both are often applied to address severe suffering in terminally ill patients. However, terminal sedation is typically used to address severe physical and psychological suffering in dying patients, whereas perceived loss of dignity during the last phase of life is a major problem for patients requesting euthanasia.

Concurrent Oral Antipsychotic Drug Use Among Schizophrenia Patients Initiated on Long-Acting Injectable Antipsychotics Post-Hospital Discharge.

Pharmacological treatment is central to effective management of schizophrenia. Prescribing clinicians have an increasing array of options from which to choose, and oral antipsychotic polypharmacy is common in routine clinical practice. Practice guidelines recommend long-acting injectable (LAI) formulations, typically viewed as monotherapeutic alternatives, for patients with established nonadherence. Yet there are limited data on the prevalence and nature of concurrent oral antipsychotic prescriptions in patients receiving LAIs. Our observational, claims-based study examined the frequency and duration of concurrent oral prescriptions in 340 Medicaid patients receiving LAI therapy. Specifically, we examined patients with a recent history of nonadherence and hospitalization for schizophrenia and included both first-generation antipsychotic depot medications (fluphenazine decanoate, haloperidol decanoate) and more recently available second-generation injectables (LAI risperidone, paliperidone palmitate). Of all patients initiated on LAIs, 75.9% had a concurrent oral antipsychotic prescription in the 6 months post-hospital discharge. Patients receiving concurrent prescriptions were frequently prescribed an oral formulation of their LAI agent, but many first-generation LAI users received a concurrent second-generation oral medication. The lowest rate of concurrent prescribing (58.8%) was found with paliperidone palmitate, whereas the highest rate was with LAI risperidone (88.9%). Overlap in oral and LAI prescriptions typically occurred for a substantial period of time (ie, >30 days) and for a notable percentage of the days covered by LAIs (often 50% or more). Our findings highlight the need to further examine such prescribing patterns, to probe the reasons for them, and to clarify the optimal roles of different antipsychotic treatments in clinical practice.

The clinical effectiveness of cognitive behaviour therapy for chronic insomnia: implementation and evaluation of a sleep clinic in general medical practice.

2001-01-01

Chronic insomnia is a very common clinical condition which may respond well to non-pharmacological treatment. Indeed, the literature supports the efficacy of cognitive behaviour therapy (CBT). However, there has been no substantial study of clinical effectiveness. Since insomniacs typically present in general medical practice this is a crucial gap in the outcome research. This study, therefore, specifically investigated the clinical effectiveness of CBT delivered by Health Visitors (primary care nurses) trained as therapists. One hundred and thirty-nine insomniacs (mean age 51 yr) were randomised to CBT or Self-Monitoring Control (SMC) in a controlled trial. CBT comprised six group sessions (n=4 to 6 patients). After the controlled phase, SMC patients entered deferred treatment (CBT-DEF), allowing both treatment replication and long-term outcome to be investigated for a sizeable, treated sample. Repeated measures ANOVAs demonstrated superiority of CBT over SMC in substantially reducing sleep latency and wakefulness during the night. CBT-DEF replicated similar effects and maintained improvement was observed in both groups one year later. Furthermore, total sleep increased significantly during follow-up and 84% of patients initially using hypnotics remained drug-free. Results suggest that CBT administered by Health Visitors offers a clinically effective treatment for insomnia.

There is often a rich but untold history of events that occurred and relationships that formed prior to the launching of a practice-based research network (PBRN.) This is particularly the case in PBRNs that are community-based and comprised of partnerships outside of the health care system. In this article we summarize an organizational "prenatal history" prior to the birth of a PBRN devoted to persons with developmental disabilities. Using a case study approach, this article describes the historical events that preceded and fostered the evolution of this PBRN and contrasts how the processes leading to the creation of this multi-stakeholder community-based PBRN differ from those of typical academic-clinical practice PBRNs. We propose potential advantages and complexities inherent to this newest iteration of PBRNs. PMID:25381081

The diagnosis of Alzheimer's disease (AD) and its related disorders rely on clinical criteria. There is, however, a large clinical overlap between the different neurodegenerative diseases affecting cognition and, frequently, there are diagnostic uncertainties with atypical clinical presentations. Current clinical practices can now regularly use positron emission tomography (PET) and single-photon emission computed tomography (SPECT) molecular imaging to help resolve such uncertainties. The Neurology Group of the French Society of Nuclear Medicine and Federations of Memory, Resources and Research Centers have collaborated to establish clinical guidelines to determine which molecular imaging techniques to use when seeking a differential diagnosis between AD and other neurodegenerative disorders affecting cognition. According to the current medical literature, the potential usefulness of molecular imaging to address the typical clinical criteria in common forms of AD remains modest, as typical AD presentations rarely raise questions of differential diagnoses with other neurodegenerative disorders. However, molecular imaging could be of significant value in the diagnosis of atypical neurodegenerative disorders, including early onset, rapid cognitive decline, prominent non-amnestic presentations involving language, visuospatial, behavioral/executive and/or non-cognitive symptoms in AD, or prominent amnestic presentations in other non-AD dementias. The clinical use of molecular imaging should be recommended for assessing cognitive disturbances particularly in patients with early clinical onset (before age 65) and atypical presentations. However, diagnostic tools should always be part of the global clinical approach, as an isolated positive result cannot adequately establish a diagnosis of any neurodegenerative disorder.

Uptake of a web-based oncology protocol system: how do cancer clinicians use eviQ cancer treatments online?

PubMed Central

2013-01-01

Background The use of computerized systems to support evidence-based practice is commonplace in contemporary medicine. Despite the prolific use of electronic support systems there has been relatively little research on the uptake of web-based systems in the oncology setting. Our objective was to examine the uptake of a web-based oncology protocol system (http://www.eviq.org.au) by Australian cancer clinicians. Methods We used web-logfiles and Google Analytics to examine the characteristics of eviQ registrants from October 2009-December 2011 and patterns of use by cancer clinicians during a typical month. Results As of December 2011, there were 16,037 registrants; 85% of whom were Australian health care professionals. During a typical month 87% of webhits occurred in standard clinical hours (08:00 to 18:00 weekdays). Raw webhits were proportional to the size of clinician groups: nurses (47% of Australian registrants), followed by doctors (20%), and pharmacists (14%). However, pharmacists had up to three times the webhit rate of other clinical groups. Clinicians spent five times longer viewing chemotherapy protocol pages than other content and the protocols viewed reflect the most common cancers: lung, breast and colorectal. Conclusions Our results demonstrate eviQ is used by a range of health professionals involved in cancer treatment at the point-of-care. Continued monitoring of electronic decision support systems is vital to understanding how they are used in clinical practice and their impact on processes of care and patient outcomes. PMID:23497080

Recruitment of representative samples in primary care research is essential to ensure high-quality, generalizable results. This is particularly important for research using routinely recorded patient data to examine the delivery of care. Yet little is known about how different recruitment strategies influence the characteristics of the practices included in research. We describe three approaches for recruiting practices to data-sharing studies, examining differences in recruitment levels and practice representativeness. We examined three studies that included varying populations of practices from West Yorkshire, UK. All used anonymized patient data to explore aspects of clinical practice. Recruitment strategies were 'opt-in', 'mixed opt-in and opt-out' and 'opt-out'. We compared aggregated practice data between recruited and not-recruited practices for practice list size, deprivation, chronic disease management, patient experience and rates of unplanned hospital admission. The opt-out strategy had the highest recruitment (80%), followed by mixed (70%) and opt-in (58%). Practices opting-in were larger (median 7153 versus 4722 patients, P = 0.03) than practices that declined to opt-in. Practices recruited by mixed approach were larger (median 7091 versus 5857 patients, P = 0.04) and had differences in the clinical quality measure (58.4% versus 53.9% of diabetic patients with HbA1c ≤ 59 mmol/mol, P < 0.01). We found no differences between practices recruited and not recruited using the opt-out strategy for any demographic or quality of care measures. Opt-out recruitment appears to be a relatively efficient approach to ensuring participation of typical general practices. Researchers should, with appropriate ethical safeguards, consider opt-out recruitment of practices for studies involving anonymized patient data sharing. © The Author 2016.

Practitioners of Western herbal medicine and their practice in the UK: beginning to sketch the profession.

PubMed

Nissen, Nina

2010-11-01

To profile the profession of Western herbal medicine (WHM) in the UK. A self-completion postal questionnaire sent to a sample of practitioners of WHM in England. A typical practitioner of WHM in the UK is female, aged 41-50, white, and practises part-time from a shared clinic or from home. Motivations to embark on a career in WHM are grounded in an interest in natural healing and the desire to help others. The practice of WHM in the UK responds extensively to women's health needs. Tensions in the practice of WHM are identified between a framework of healthcare that is described as 'traditional' and the influences of evidence-based developments in healthcare. Women, both as practitioners and as patients, and women's health needs play a central role in the contemporary practice of WHM in the UK. Copyright © 2010 Elsevier Ltd. All rights reserved.

Remote nursing certified practice: viewing nursing and nurse practitioner practice through a social justice lens.

PubMed

Tarlier, Denise S; Browne, Annette J

2011-06-01

Remote Nursing Certified Practice (RNCP) was introduced in 2010 to regulate nursing practice in remote, largely First Nations communities in British Columbia, Canada. These are communities that often experience profound health and health-care inequities. Typically nurses are the main health-care providers. Using a critical social justice lens, the authors explore the clinical and ethical implications of RNCP in terms of access to equitable, high-quality primary health care.They examine the fit between the level and scope of health services provided by registered nurses working under RNCP and the health needs of remote First Nations communities. In doing so, they draw comparisons between nurse practitioners (NPs) and outpost nurses working in NP roles who historically were employed to provide health care in these communities.The authors conclude by calling for nursing regulations that support equitable, high-quality primary care for all British Columbians.

Urbanová, Jana; Brunerová, Ludmila; Brož, Jan

2018-01-01

Maturity Onset Diabetes of the Young (MODY) comprises inherited forms of diabetes mellitus caused by the mutations in the genes involved in the development, differentiation and function of beta-cells. The majority of patients with MODY remains misdiagnosed and erroneously classified as type 1 or type 2 diabetic patients. Correct MODY diagnosis is, however, essential since it enables individualization of treatment, assessment of the prognosis and identification of diabetes among patient´s relatives. Clinical presentation of MODY is highly variable and it could resemble other types of diabetes, thus identification of MODY patients might be difficult. In this review, we describe typical clinical presentation of the most common MODY subtypes, we summarize current diagnostic guidelines in confirmation of MODY and we raise the question of possible need for extension of current clinical criteria indicating a patient for molecular-genetic testing.Key words: clinical course - diagnosis - differential diagnosis - glucokinase - hepatocyte nuclear factors - MODY.

Teenagers like to draw. A drawing is a fundamental object of creativity in the process of re-construction and change typical of this period. However, theoretical approaches often consider that the evolution of the stages of drawing come to an end in adolescence. It is important to consider the practical and clinical benefit of drawing and to develop expression-based activities which can be carried out with this population.

Deferoxamine mesylate (DFO) reduces morbidity and mortality associated with transfusional iron overload. Data on the utilization and costs of care among U.S. patients receiving DFO in typical clinical practice are limited however. This was a retrospective study using a large U.S. health insurance claims database spanning 1/97-12/04 and representing 40 million members in >70 health plans. Study subjects (n = 145 total, 106 sickle cell disease [SCD], 39 thalassemia) included members with a diagnosis of thalassemia or SCD, one or more transfusions (whole blood or red blood cells), and one or more claims for DFO. Mean transfusion episodes were 12 per year. Estimated mean DFO use was 307 g/year. Central venous access devices were required by 20% of patients. Cardiac disease was observed in 16% of patients. Mean total medical costs were $59,233 per year including $10,899 for DFO and $8,722 for administration of chelation therapy. In multivariate analyses, potential complications of iron overload were associated with significantly higher medical care costs. In typical clinical practice, use of DFO in patients with thalassemia and SCD receiving transfusions is low. Administration costs represent a large proportion of the cost of chelation therapy. Potential complications of iron overload are associated with increased costs. (c) 2007 Wiley-Liss, Inc.

Legal Issues for the Medical Director.

PubMed

Trulove, William G

2015-09-04

The nephrologist serving as medical director of a dialysis clinic must understand that the role of director is not simply an extension of being a good nephrologist. The two roles-nephrology practice and the leadership of a dialysis clinic-may be filled by a single person. However, each role contains unique tasks, requiring specific skill sets, and each role comes with inherent, associated legal risks. The medical director assumes a new level of responsibility and accountability defined by contractual obligations to the dialysis provider and by state and federal regulations. Hence, a medical director is accountable not only for providing standard-of-care treatment to his or her private practice patients dialyzed at the clinic but also for maintaining the safety of the dialysis clinic patient population and staff. Accordingly, a nephrologist serving in the role of medical director faces distinct legal risks beyond typical professional liability concerns. The medical director must also be mindful of regulatory compliance, unique avenues to licensure board complaints, and implications of careless communication habits. A thoughtful and prepared medical director can mitigate these risk exposures by understanding the sources of these challenges: contractual obligations, pertinent regulatory responsibilities, and the modern electronic communications environment.

Melatonin exerts its actions through membrane MT1/MT2 melatonin receptors, which belong to the super family of G-protein-coupled receptors consisting of the typical seven transmembrane domains. MT1 and MT2 receptors are expressed in various tissues of the body either as single ones or together. A growing literature suggests that the melatonergic system may be involved in the pathophysiology of mood and anxiety disorders. In fact, some core symptoms of depression show disturbance of the circadian rhythm in their clinical expression, such as diurnal mood and other symptomatic variation, or are closely linked to circadian system functioning, such as sleep-wake cycle alterations. In addition, alterations have been described in the circadian rhythms of several biological markers in depressed patients. Therefore, there is interest in developing antidepressants that have a chronobiotic effect (i.e., treatment of circadian rhythm disorders). As melatonin produces chronobiotic effects, efforts have been aimed at developing agomelatine, an antidepressant with melatonin agonist activity. The present paper reviews the role of the melatonergic system in the pathophysiology of mood and anxiety disorders and the clinical characteristics of agomelatine. Implications of agomelatine in "real world" clinical practice will be also discussed.

How can primary care providers manage pediatric obesity in the real world?

To provide information regarding evidence-based interventions and clinical practice guidelines as a basis for a clinical toolkit utilizing a step management approach for the primary care provider in managing childhood obesity. Evidence-based literature including original clinical trials, literature reviews, and clinical practice guidelines. Interventions can be stratified based on initial screening of children and adolescents so that selection of treatment options is optimized. For all treatments, lifestyle modifications include attention to diet and activity level. Levels of initial success, as well as maintenance of target body mass index, may be related to the intensity and duration of interventions; involvement of family may increase success rates. For failed lifestyle interventions, or for patients with extreme obesity and/or certain comorbidities, pharmacologic or surgical options should be considered. Many intensive programs have shown success, but the resources required for these approaches may be unavailable to the typical community provider and family. However, using current guidelines, the primary care provider can initiate and manage ongoing interventions in pediatric obesity. A toolkit for primary care implementation and maintenance interventions is provided. ©2011 The Author(s) Journal compilation ©2011 American Academy of Nurse Practitioners.

The objective of this randomized clinical experiment was to test the influence of a mindfulness meditation practice, when delivered during 1 session of active chemotherapy administration, on the acute salivary cortisol response as a marker of neuroendocrine system activity in cancer patients. A mindfulness, attention-control, or resting exposure was assigned to 57 English- or Spanish-speaking colorectal cancer patients at 1 county oncology clinic and 1 university oncology clinic at the start of chemotherapy. Saliva samples were collected at the start of chemotherapy and at subsequent 20-minute intervals during the first 60 minutes of chemotherapy (4 samples in all). Self-reporting on biobehavioral assessments after chemotherapy included distress, fatigue, and mindfulness. An area-under-the-curve analysis (AUC) showed a relative increase in cortisol reactivity in the mindfulness group after adjustments for biological and clinical measures (β = 123.21; P = .03). More than twice as many patients in the mindfulness group versus the controls displayed a cortisol rise from the baseline to 20 minutes (69% vs 34%; P = .02). AUC values were uncorrelated with biobehavioral measure scores, although mindfulness scores were inversely correlated with fatigue (r = -0.46; P < .01) and distress scores (r = -0.54; P < .01). Findings suggest that mindfulness practice during chemotherapy can reduce the blunting of neuroendocrine profiles typically observed in cancer patients. Implications include support for the use of mindfulness practice in integrative oncology. Cancer 2017;123:3088-96. © 2017 American Cancer Society. © 2017 American Cancer Society.

Clinical reasoning is essential to physical therapist practice. Solid clinical reasoning processes may lead to greater understanding of the patient condition, early diagnostic hypothesis development, and well-tolerated examination and intervention strategies, as well as mitigate the risk of diagnostic error. However, the complex and often subconscious nature of clinical reasoning can impede the development of this skill. Protracted tools have been published to help guide self-reflection on clinical reasoning but might not be feasible in typical clinical settings. This case illustrates how the Systematic Clinical Reasoning in Physical Therapy (SCRIPT) tool can be used to guide the clinical reasoning process and prompt a physical therapist to search the literature to answer a clinical question and facilitate formal mentorship sessions in postprofessional physical therapist training programs. The SCRIPT tool enabled the mentee to generate appropriate hypotheses, plan the examination, query the literature to answer a clinical question, establish a physical therapist diagnosis, and design an effective treatment plan. The SCRIPT tool also facilitated the mentee's clinical reasoning and provided the mentor insight into the mentee's clinical reasoning. The reliability and validity of the SCRIPT tool have not been formally studied. Clinical mentorship is a cornerstone of postprofessional training programs and intended to develop advanced clinical reasoning skills. However, clinical reasoning is often subconscious and, therefore, a challenging skill to develop. The use of a tool such as the SCRIPT may facilitate developing clinical reasoning skills by providing a systematic approach to data gathering and making clinical judgments to bring clinical reasoning to the conscious level, facilitate self-reflection, and make a mentored physical therapist's thought processes explicit to his or her clinical mentor. © 2017 American Physical Therapy Association

The GH-IGF-I response to typical field sports practices in adolescent athletes: a summary.

2014-11-01

The present study compares previous reports on the effect of "real-life" typical field individual (i.e., cross-country running and wrestling--representing combat versus noncombat sports) and team sports (i.e., volleyball and water polo-representing water and land team sports) training on GH and IGF-1, the main growth factors of the GH→IGF axis, in male and female late pubertal athletes. Cross-country running practice and volleyball practice in both males and females were associated with significant increases of circulating GH levels, while none of the practices led to a significant increase in IGF-I levels. The magnitude (percent change) of the GH response to the different practices was determined mainly by preexercise GH levels. There was no difference in the training-associated GH response between individual and team sports practices. The GH response to the different typical practices was not influenced by the practice-associated lactate change. Further studies are needed to better understand the effect of real-life typical training in prepubertal and adolescent athletes and their role in exercise adaptations.

This article describes the impact of an 8-week community program implemented by trained volunteers on the hypertension self-management of 185 patients who were batch randomized to intervention or wait-list control groups. Compared with control group participants, a higher proportion of treatment group participants moved from the cognitive to behavioral stages of motivational readiness for being physically active (P < .001), practicing healthy eating habits (P = .001), handling stress well (P = .001), and living an overall healthy lifestyle (P = .003). They also demonstrated a greater average increase in perceived competence for self-management, F(1.134) = 4.957, P = .028, η2 = .036, and a greater increase in mean hypertension-related knowledge, F(1.160) = 16.571, P < .0005, η(2) = .094. Enduring lifestyle changes necessary for chronic disease self-management require that psychosocial determinants of health behavior are instilled, which is typically beyond standard medical practice. We recommend peer-led, community-based programs as a complement to clinical care and support the increasing health system interest in promoting population health beyond clinical walls. © The Author(s) 2016.

PROBLEM ADDRESSED: In addition to clinical instruction, residents need "people" skills that will enable them to deal with all sorts of patients in difficult clinical situations. We planned a series of 12 seminars to teach these skills to first-year residents. OBJECTIVES OF PROGRAM: To ask relevant questions typical of the patient-centred approach; with empathy and respect, to encourage patients to express their emotions; to become more aware of one's own emotions and reactions in one's work as a physician; to negotiate with patients, taking into account both the patient's agenda and one's own. MAIN COMPONENTS OF PROGRAM: Clinical problems drawn from a list of situations likely to involve difficult contact with patients were used to achieve program objectives. Various teaching methods (discussion, brief presentation, practical demonstration, role play) were used during the four stages of skills development: information, demonstration, practice, and feedback. Various tools were used to test the program. CONCLUSION: Proper planning requires ongoing exploration of objectives, content, teaching methods, and evaluation. This discussion of the teaching principles applied in planning our seminars might inspire others to develop similar programs. PMID:10349069

The number of Natural Language Processing (NLP) tools and systems for processing clinical free-text has grown as interest and processing capability have surged. Unfortunately any two systems typically cannot simply interoperate, even when both are built upon a framework designed to facilitate the creation of pluggable components. We present two ongoing activities promoting open source clinical NLP. The Open Health Natural Language Processing (OHNLP) Consortium was originally founded to foster a collaborative community around clinical NLP, releasing UIMA-based open source software. OHNLP’s mission currently includes maintaining a catalog of clinical NLP software and providing interfaces to simplify the interaction of NLP systems. Meanwhile, Apache cTAKES aims to integrate best-of-breed annotators, providing a world-class NLP system for accessing clinical information within free-text. These two activities are complementary. OHNLP promotes open source clinical NLP activities in the research community and Apache cTAKES bridges research to the health information technology (HIT) practice. PMID:25954581

Surrogate decision making: reconciling ethical theory and clinical practice.

Berger, Jeffrey T; DeRenzo, Evan G; Schwartz, Jack

2008-07-01

The care of adult patients without decision-making abilities is a routine part of medical practice. Decisions for these patients are typically made by surrogates according to a process governed by a hierarchy of 3 distinct decision-making standards: patients' known wishes, substituted judgments, and best interests. Although this framework offers some guidance, it does not readily incorporate many important considerations of patients and families and does not account for the ways in which many patients and surrogates prefer to make decisions. In this article, the authors review the research on surrogate decision making, compare it with normative standards, and offer ways in which the 2 can be reconciled for the patient's benefit.

2005-01-01

Unlike most other industries in which company employees are, well, company employees, U.S. hospitals are typically run by both employees (nurses, technicians, and administrative staff) and independent entrepreneurs (physicians and nurse practitioners). Therefore, major enterprise-wide clinical IT projects can never simply be implemented by mandate. Project management processes in these environments must rely on methods that influence adoption rather than presume adoption will occur. "Build it and they will come" does not work in a hospital setting. This paper outlines a large academic medical center's experiences in managing an enterprise-wide project to replace its core clinical systems functionality. Best practices include developing a cogent optimal future-state vision, communications planning and execution, vendor validation against the optimal future-state vision, and benefits realization assessment.

Clinical psychologists' experiences of reflective staff groups in inpatient psychiatric settings: a mixed methods study.

2014-01-01

Background Reflective practice groups have been recommended for improving staff wellbeing and team functioning in inpatient psychiatric services, and clinical psychologists have been identified as potential leaders in this type of work. Research is limited with little information about reflective practice group guidelines, prevalence and effectiveness. Aims The aims of this study were to describe clinical psychologists' practice in reflective groups for staff in inpatient psychiatric services and to explore how such groups are conceptualized and implemented. Methods Online questionnaires and follow-up interviews were used to gain broad descriptions of practice and in-depth information about participants' experiences. The sample consisted of 73 clinical psychologists working in the UK, six of whom were interviewed. Data were analysed using descriptive statistics, content analysis and thematic analysis. Results Clinical psychologists regularly facilitate reflective staff groups in inpatient psychiatric settings in the UK. Common outcomes related to staff wellbeing, service culture and teamwork. Engagement, group dynamics and lack of management support were common challenges. Group experiences were influenced by the organizational context. Conclusions Clinical psychologists' practices regarding reflective staff groups were in line with recent professional developments. Several difficulties were described, which may be indicative of both a difficulty inherent to the task and a training gap in reflective staff group process. The study had methodological limitations but offers a useful contribution to the literature, and enables practice and training implications to be drawn. The need for further research exploring facilitator characteristics, views of group participants and the impact of reflective staff groups on patients is indicated. The term 'reflective practice group' encompasses a range of practices, but a typical group structure was found with common aims, outcomes and challenges. Reflective staff groups are regularly facilitated by clinical psychologists in inpatient psychiatric settings in the UK and are influenced by practitioner experience as well as psychodynamic, systemic and group process theories. The safety required for reflective groups to function is influenced by the organizational context, and groups can contribute to shifts in culture toward including psychosocial perspectives. Reflective staff groups represent one type of contribution to an inpatient psychiatric service and team relationships; other processes to encourage alternative professional perspectives and values might also support change. More research is recommended to explore facilitator characteristics, the views of staff teams on reflective staff groups and the impact of these groups on patients.

A case of periorbital and eyelid edema in an eighteen-year-old student is presented as the initial manifestation of acute infectious mononucleosis occurring one week before the typical prodrome. Although periorbital and eyelid edema have been reported in about 50 percent of patients with early infectious mononucleosis, its occurrence is much less frequent in clinical practice. Physicians, particularly those specializing in the treatment of cutaneous and ocular diseases, should now include acute infectious mononucleosis in the differential diagnosis of periorbital and eyelid edema.

MO-G-9A-01: Imaging Refresher for Standard of Care Radiation Therapy

2014-06-15

Imaging techniques and technology which were previously the domain of diagnostic medicine are becoming increasingly integrated and utilized in radiation therapy (RT) clinical practice. As such, there are a number of specific imaging topics that are highly applicable to modern radiation therapy physics. As imaging becomes more widely integrated into standard clinical radiation oncology practice, the impetus is on RT physicists to be informed and up-to-date on those imaging modalities relevant to the design and delivery of therapeutic radiation treatments. For example, knowing that, for a given situation, a fluid attenuated inversion recovery (FLAIR) image set is most likely whatmore » the physician would like to import and contour is helpful, but may not be sufficient to providing the best quality of care. Understanding the physics of how that pulse sequence works and why it is used could help assess its utility and determine if it is the optimal sequence for aiding in that specific clinical situation. It is thus important that clinical medical physicists be able to understand and explain the physics behind the imaging techniques used in all aspects of clinical radiation oncology practice. This session will provide the basic physics for a variety of imaging modalities for applications that are highly relevant to radiation oncology practice: computed tomography (CT) (including kV, MV, cone beam CT [CBCT], and 4DCT), positron emission tomography (PET)/CT, magnetic resonance imaging (MRI), and imaging specific to brachytherapy (including ultrasound and some brachytherapy specific topics in MR). For each unique modality, the image formation process will be reviewed, trade-offs between image quality and other factors (e.g. imaging time or radiation dose) will be clarified, and typically used cases for each modality will be introduced. The current and near-future uses of these modalities and techniques in radiation oncology clinical practice will also be discussed. Learning Objectives: To review the basic physical science principles of CT, PET, MR, and ultrasound imaging. To understand how the images are created, and present their specific role in patient management and treatment planning for therapeutic radiation (both external beam and brachytherapy). To discuss when and how each specific imaging modality is currently used in clinical practice, as well as how they may come to be used in the near future.« less

International Practice in Care Provision for Post-stroke Visual Impairment.

PubMed

Rowe, Fiona J

2017-09-01

This study sought to explore the practice of orthoptists internationally in care provision for poststroke visual impairment. Survey questions were developed and piloted with clinicians, academics, and users. Questions addressed types of visual problems, how these were identified, treated, and followed up, care pathways in use, links with other professions, and referral options. The survey was approved by the institutional ethical committee. The survey was accessed via a web link that was circulated through the International Orthoptic Association member professional organisations to orthoptists. Completed electronic surveys were obtained from 299 individuals. About one-third (35.5%) of orthoptists saw patients within 2 weeks of stroke onset and over half (55.5%) by 1 month post stroke. Stroke survivors were routinely assessed by 87%; over three-quarters in eye clinics. Screening tools were used by 11%. Validated tests were used for assessment of visual acuity (76.5%), visual field (68.2%), eye movement (80.9%), binocular vision (77.9%), and visual function (55.8%). Visual problems suspected by family or professionals were high (86.6%). Typical overall follow-up period of vision care was less than 3 months. Designated care pathways for stroke survivors with visual problems were used by 56.9% of orthoptists. Information on visual impairment was provided by 85.9% of orthoptists. In international orthoptic practice, there is general agreement on assessment and management of visual impairment in stroke populations. More than half of orthoptists reported seeing stroke survivors within 1 month of the stroke onset, typically in eye clinics. There was a high use of validated tests of visual acuity, visual fields, ocular motility, and binocular vision. Similarly there was high use of established treatment options including prisms, occlusion, compensatory strategies, and oculomotor training, appropriately targeted at specific types of visual conditions/symptoms. This information can be used to inform choice of core outcome orthoptic measures in stroke practice.

Renal sympathetic denervation is currently performed in the treatment of resistant hypertension by interventionists who otherwise do not typically use radiofrequency (RF) energy ablation in their clinical practice. Adequate RF lesion formation is dependent upon good electrode-tissue contact, power delivery, electrode-tissue interface temperature, target-tissue impedance and the size of the catheter's active electrode. There is significant interplay between these variables and hence an appreciation of the biophysical determinants of RF lesion formation is required to provide effective and safe clinical care to our patients. In this review article, we summarize the biophysics of RF ablation and explain why and how complications of renal sympathetic denervation may occur and discuss methods to minimise them.

The Mediterranean diet: is it cardioprotective?

PubMed

Bautista, Marita C; Engler, Margurite M

2005-01-01

Coronary heart disease is one of the leading causes of morbidity and mortality in the United States. Dietary interventions are first-line therapy for coronary heart disease prevention and treatment. Increasing scientific evidence suggests that the traditional Mediterranean diet may reduce the risk of cardiovascular disease. The cardiovascular benefits of this whole-diet approach may outweigh those of typically prescribed low-fat diets. The burden of coronary heart disease is enormous, and nutritional approaches that optimize cardiovascular health are essential. Clinical trial evidence supporting the role of the Mediterranean diet in cardiovascular health is presented with an emphasis on the physiological effects of omega-3 fatty acids. Implications for clinical practice and future research are also discussed.

Patients with first episode schizophrenia may present in a variety of clinical settings to providers who have a range of knowledge and skills. A thoughtful workup of patients with new-onset psychosis is critical, and the treatment of first episode schizophrenia differs from that of chronic psychotic disorders. Clinical case vignettes with free-form responses can be used to carefully assess whether front line practitioners provide guideline-adherent management of first episode psychosis. A clinical case vignette, presenting a patient with first episode schizophrenia, was created and administered to the attendees of a continuing medical education programme. Free-form responses to questions regarding differential diagnosis, workup, treatment and treatment duration were scored based on published practice guidelines. Response frequencies were tabulated and performance was compared among professional disciplines. Sixty-two attendees completed the vignette. Though the attendees typically considered a broad differential diagnosis and appropriately initiated treatment with antipsychotics, the respondents' proposed medical workup was limited, and they prescribed antipsychotics at higher doses and for a shorter duration than recommended in the literature. The prescribers outperformed the non-prescribers on treatment questions (P = 0.006), but the two groups' performance did not significantly differ on the assessment questions (P = 0.08). The front line clinicians who encounter patients with first episode schizophrenia may have significant practice gaps in the initial and follow-up care of these patients. Given the preliminary nature of this study and the debate about the optimal care for first episode psychosis, further study is needed. If such gaps are confirmed, additional educational interventions are required to align clinical management with published practice guidelines.

The Clinical Assessment in the Legal Field: An Empirical Study of Bias and Limitations in Forensic Expertise

Iudici, Antonio; Salvini, Alessandro; Faccio, Elena; Castelnuovo, Gianluca

2015-01-01

According to the literature, psychological assessment in forensic contexts is one of the most controversial application areas for clinical psychology. This paper presents a review of systematic judgment errors in the forensic field. Forty-six psychological reports written by psychologists, court consultants, have been analyzed with content analysis to identify typical judgment errors related to the following areas: (a) distortions in the attribution of causality, (b) inferential errors, and (c) epistemological inconsistencies. Results indicated that systematic errors of judgment, usually referred also as “the man in the street,” are widely present in the forensic evaluations of specialist consultants. Clinical and practical implications are taken into account. This article could lead to significant benefits for clinical psychologists who want to deal with this sensitive issue and are interested in improving the quality of their contribution to the justice system.

2015-01-01

Neurogastroenterology and motility disorders of the gastrointestinal (GI) tract encompass a broad spectrum of diseases involving the GI tract and central nervous system. They have varied pathophysiology, clinical presentation and management, and make up a substantial proportion of outpatient clinic visits. Typically, patients experience persistent symptoms referable to the GI tract despite normal endoscopic and radiologic findings. An appropriate evaluation is thus important in the patient’s care. Advances in technology and understanding of the disease pathophysiology have provided better insight into the physiological basis of disease and a more rational approach to patient management. While technological advances serve to explain patients’ persistent symptoms, they should be balanced against the costs of diagnostic tests. This review highlights the GI investigative modalities employed to evaluate patients with persistent GI symptoms in the absence of a structural lesion, with particular emphasis on investigative modalities available locally and the clinical impact of such tools.

Diagnostic Approach to Ocular Toxoplasmosis

PubMed Central

Garweg, Justus G; de Groot-Mijnes, Jolanda DF; Montoya, Jose G

2011-01-01

Toxoplasmic retinochoroiditis is deemed a local event, which may fail to evoke a detectable systemic immune response. A correct diagnosis of the disease is a necessary basis for estimating its clinical burden. This is not so difficult in a typical clinical picture. In atypical cases, further diagnostic efforts are to be installed. Although the aqueous humor may be analyzed for specific antibodies or the presence of parasitic DNA, the DNA burden therein is low, and in rare instances a confirmation would necessitate vitreous sampling. A laboratory confirmation of the diagnosis is frustrated by individual differences in the time elapsing between clinical symptoms and activation of specific antibody production, which may result in false negatives. In congenital ocular toxoplasmosis, a delay in the onset of specific local antibody production could reflect immune tolerance. Herein, the authors attempt to provide a simple and practicable algorithm for a clinically tailored diagnostic approach in atypical instances. PMID:21770803

Viral bronchiolitis.

Florin, Todd A; Plint, Amy C; Zorc, Joseph J

2017-01-14

Viral bronchiolitis is a common clinical syndrome affecting infants and young children. Concern about its associated morbidity and cost has led to a large body of research that has been summarised in systematic reviews and integrated into clinical practice guidelines in several countries. The evidence and guideline recommendations consistently support a clinical diagnosis with the limited role for diagnostic testing for children presenting with the typical clinical syndrome of viral upper respiratory infection progressing to the lower respiratory tract. Management is largely supportive, focusing on maintaining oxygenation and hydration of the patient. Evidence suggests no benefit from bronchodilator or corticosteroid use in infants with a first episode of bronchiolitis. Evidence for other treatments such as hypertonic saline is evolving but not clearly defined yet. For infants with severe disease, the insufficient available data suggest a role for high-flow nasal cannula and continuous positive airway pressure use in a monitored setting to prevent respiratory failure.

Clinical utility of bone turnover markers in the management of common metabolic bone diseases in adults.

PubMed

Glendenning, Paul; Chubb, S A Paul; Vasikaran, Samuel

2018-06-01

Bone turnover marker (BTMs) concentrations in blood and urine reflect bone-remodelling activity, and may be useful adjuncts in the diagnosis and management of metabolic bone diseases. Newer biomarkers, mainly bone regulatory proteins, are currently being investigated to elucidate their role in bone metabolism and disease and may in future be useful in clinical diagnosis and management of metabolic bone disease. BTM concentrations increase around menopause in women, and at a population level the degree of increase in BTMs reflect bone loss. However, lack of adequate data precludes their use in individual patients for fracture risk assessment in clinical practice. The rapid and large changes in BTMs following anti-resorptive and anabolic therapies for osteoporosis treatment indicate they may be useful for monitoring therapy in clinical practice. The offset of drug effect on BTMs could be helpful for adjudicating the duration of bisphosphonate drug holidays. BTMs may offer useful additional data in skeletal diseases that are typically characterised by increased bone remodelling: chronic kidney disease (CKD), primary hyperparathyroidism (PHPT) and Paget's disease. In CKD, bone specific alkaline phosphatase (bAP) is currently endorsed for use for the assessment of mineral bone disease. The role of BTMsin predicting the bone mineral density response to successful parathyroidectomy in PHPT shows some utility but the data are not consistent and studies are limited in size and/or duration. In Paget's disease of bone, BTMs are used to confirm diagnosis, evaluate extent of disease or degree of activity and for monitoring the response to bisphosphonate treatment. Whilst BTMs are currently used in specific clinical practice instances when investigating or managing metabolic bone disease, further data are needed to consolidate their clinical use where evidence of utility is limited.

Vodovatov, A V; Balonov, M I; Golikov, V Yu; Shatsky, I G; Chipiga, L A; Bernhardsson, C

2017-04-01

In 2009-2014, dose surveys aimed to collect adult patient data and parameters of most common radiographic examinations were performed in six Russian regions. Typical patient doses were estimated for the selected examinations both in entrance surface dose and in effective dose. 75%-percentiles of typical patient effective dose distributions were proposed as preliminary regional diagnostic reference levels (DRLs) for radiography. Differences between the 75%-percentiles of regional typical patient dose distributions did not exceed 30-50% for the examinations with standardized clinical protocols (skull, chest and thoracic spine) and a factor of 1.5 for other examinations. Two different approaches for establishing national DRLs were evaluated: as a 75%-percentile of a pooled regional sample of patient typical doses (pooled method) and as a median of 75%-percentiles of regional typical patient dose distributions (median method). Differences between pooled and median methods for effective dose did not exceed 20%. It was proposed to establish Russian national DRLs in effective dose using a pooled method. In addition, the local authorities were granted an opportunity to establish regional DRLs if the local radiological practice and typical patient dose distributions are significantly different. © The Author 2016.

Abstract Needle fear typically begins in childhood and represents an important health-related issue across the lifespan. Individuals who are highly fearful of needles frequently avoid health care. Although guidance exists for managing needle pain and fear during procedures, the most highly fearful may refuse or abstain from such procedures. The purpose of a clinical practice guideline (CPG) is to provide actionable instruction on the management of a particular health concern; this guidance emerges from a systematic process. Using evidence from a rigorous systematic review interpreted by an expert panel, this CPG provides recommendations on exposure-based interventions for high levels of needle fear in children and adults. The AGREE-II, GRADE, and Cochrane methodologies were used. Exposure-based interventions were included. The included evidence was very low quality on average. Strong recommendations include the following. In vivo (live/in person) exposure-based therapy is recommended (vs. no treatment) for children seven years and older and adults with high levels of needle fear. Non-in vivo (imaginal, computer-based) exposure (vs. no treatment) is recommended for individuals (over seven years of age) who are unwilling to undergo in vivo exposure. Although there were no included trials which examined children < 7 years, exposure-based interventions are discussed as good clinical practice. Implementation considerations are discussed and clinical tools are provided. Utilization of these recommended practices may lead to improved health outcomes due to better health care compliance. Research on the understanding and treatment of high levels of needle fear is urgently needed; specific recommendations are provided. PMID:27007463

The past decade has provided many technological advances in radiotherapy. The European Institute of Radiotherapy (EIR) was established by the European Society of Therapeutic Radiology and Oncology (ESTRO) to provide current consensus statement with evidence-based and pragmatic guidelines on topics of practical relevance for radiation oncology. This report focuses primarily on 3D CT-based in-room image guidance (3DCT-IGRT) systems. It will provide an overview and current standing of 3DCT-IGRT systems addressing the rationale, objectives, principles, applications, and process pathways, both clinical and technical for treatment delivery and quality assurance. These are reviewed for four categories of solutions; kV CT and kV CBCT (cone-beam CT) as well as MV CT and MV CBCT. It will also provide a framework and checklist to consider the capability and functionality of these systems as well as the resources needed for implementation. Two different but typical clinical cases (tonsillar and prostate cancer) using 3DCT-IGRT are illustrated with workflow processes via feedback questionnaires from several large clinical centres currently utilizing these systems. The feedback from these clinical centres demonstrates a wide variability based on local practices. This report whilst comprehensive is not exhaustive as this area of development remains a very active field for research and development. However, it should serve as a practical guide and framework for all professional groups within the field, focussed on clinicians, physicists and radiation therapy technologists interested in IGRT.

Keeping experience at the bedside: the emergency consultant nurse role.

PubMed

Currie, Jane

The consultant nurse concept has not yet been transferred to the military setting. The motivation for developing the role in the NHS was to improve the quality of patient care by strengthening professional leadership and extending the clinical career ladder. The consultant nurse may be defined as an expert in their clinical field, possessing expert leadership and visionary skills. The role is based on four domains: expert practice, professional leadership, education and research. Typically, the emergency consultant nurse spends 50% of their time working clinically, thereby providing senior clinical expertise and adding value to the clinical role. In a military context the consultant nurse role could be perceived as the coming together of the senior command and administrative role and the clinical role. The military has the opportunity to develop a senior clinical emergency nurse role encompassing elements of the civilian consultant nurse model, which may strengthen leadership, provide a central resource of expertise and raise the profile of military nursing. This has the added potential to provide inspiration for junior nurses and retain experienced emergency nurses in the clinical arena.

From the Consulting Room to the Court Room? Taking the Clinical Model of Responsibility Without Blame into the Legal Realm.

PubMed

Lacey, Nicola; Pickard, Hanna

2013-03-01

Within contemporary penal philosophy, the view that punishment can only be justified if the offender is a moral agent who is responsible and hence blameworthy for their offence is one of the few areas on which a consensus prevails. In recent literature, this precept is associated with the retributive tradition, in the modern form of 'just deserts'. Turning its back on the rehabilitative ideal, this tradition forges a strong association between the justification of punishment, the attribution of responsible agency in relation to the offence, and the appropriateness of blame. By contrast, effective clinical treatment of disorders of agency employs a conceptual framework in which ideas of responsibility and blameworthiness are clearly separated from what we call 'affective blame': the range of hostile, negative attitudes and emotions that are typical human responses to criminal or immoral conduct. We argue that taking this clinical model of 'responsibility without blame' into the legal realm offers new possibilities. Theoretically, it allows for the reconciliation of the idea of 'just deserts' with a rehabilitative ideal in penal philosophy. Punishment can be reconceived as consequences-typically negative but occasionally not, so long as they are serious and appropriate to the crime and the context-imposed in response to, by reason of, and in proportion to responsibility and blameworthiness, but without the hard treatment and stigma typical of affective blame. Practically, it suggests how sentencing and punishment can better avoid affective blame and instead further rehabilitative and related ends, while yet serving the demands of justice.

Clinical test responses to different orthoptic exercise regimes in typical young adults

Horwood, Anna; Toor, Sonia

2014-01-01

Purpose The relative efficiency of different eye exercise regimes is unclear, and in particular the influences of practice, placebo and the amount of effort required are rarely considered. This study measured conventional clinical measures following different regimes in typical young adults. Methods A total of 156 asymptomatic young adults were directed to carry out eye exercises three times daily for 2 weeks. Exercises were directed at improving blur responses (accommodation), disparity responses (convergence), both in a naturalistic relationship, convergence in excess of accommodation, accommodation in excess of convergence, and a placebo regime. They were compared to two control groups, neither of which were given exercises, but the second of which were asked to make maximum effort during the second testing. Results Instruction set and participant effort were more effective than many exercises. Convergence exercises independent of accommodation were the most effective treatment, followed by accommodation exercises, and both regimes resulted in changes in both vergence and accommodation test responses. Exercises targeting convergence and accommodation working together were less effective than those where they were separated. Accommodation measures were prone to large instruction/effort effects and monocular accommodation facility was subject to large practice effects. Conclusions Separating convergence and accommodation exercises seemed more effective than exercising both systems concurrently and suggests that stimulation of accommodation and convergence may act in an additive fashion to aid responses. Instruction/effort effects are large and should be carefully controlled if claims for the efficacy of any exercise regime are to be made. PMID:24471739

We report the case of a 48-year-old, Caucasian female who presented with slowly progressing asymptomatic poikilodermatous changes of the extensor aspects of the forearms. She also had typical Poikiloderma of Civatte on the V of the neck and erythemato-telangiectatic rosacea of the central face. The patient had been practicing aroma-therapy for many years. Histologic examination revealed findings consistent with PC. Patch-testing revealed positive reactions to Fragrance mix and Nickel sulphate. Based on clinical and histological findings, a diagnosis of extracervical PC was suggested. PC with extra-cervical or extra-facial involvement is rare. In addition, this case supports the theory that contact sensitization to fragrances may contribute to the development of PC. PMID:25054757

Abstract Background. Thyroid dysfunction and hypertension (HTN) have been sporadically reported with sunitinib (SUN) and sorafenib (SOR). Determination of the side effect incidence will enhance monitoring and management recommendations. Methods. An observational cohort study was performed using deidentified pharmacy claims data from a 3‐year period to evaluate patients prescribed SUN, SOR, or capecitabine (CAP; comparison group). The primary outcome was time to first prescription for thyroid replacement or HTN treatment. Hazard ratios (HRs) with 95% confidence intervals (CIs) were estimated by Cox proportional hazards models. Results. A total of 20,061 patients were eligible for evaluation of thyroid replacement therapy, which was initiated in 11.6% of those receiving SUN (HR, 16.77; 95% CI, 13.54–20.76), 2.6% of those receiving SOR (HR, 3.47; 95% CI, 2.46–4.98), and 1% of those receiving CAP, with median time to initiation of 4 months (range, 1–35 months). A total of 14,468 patients were eligible for evaluation of HTN therapy, which was initiated in 21% of SUN recipients (HR, 4.91; 95% CI, 4.19–5.74), 14% of SOR recipients (HR, 3.25; 95% CI, 2.69–3.91), and 5% of CAP recipients, with median time to initiation of 1 month (range, 1–18 months) for SOR and 2 months (range, 1–25 months) for SUN. Conclusion. SUN and SOR significantly increased the risk for clinically relevant hypothyroidism; the risk was at least 4 times greater with SUN than with SOR. Patients receiving SUN and SOR had a similar elevated risk for clinically relevant HTN. These data provide robust measures of the incidence and time to onset of these clinically actionable adverse events. Implications for Practice. The side effect profiles for novel therapies are typically used to create monitoring and management recommendations using clinical trial data from patient populations that may not represent those seen in standard clinical practice. This analysis using a large pharmacy claims database better reflects typical patients treated with sorafenib or sunitinib outside of a clinical trial. The findings of increased need for thyroid replacement in patients receiving sunitinib compared with sorafenib and a similar increase in need for hypertension therapy with both agents can be used to form clinically relevant monitoring recommendations for these agents.

Background: Social workers entering the profession typically receive little, if any, content or training on evaluation practice. This is, in part, due to limited course offerings outside of the typical courses in most schools of social work. In addition, practicing social workers who often serve in the role as field instructors have not fully…

Despite evidence supporting restrictive red blood cell (RBC) transfusion thresholds and the associated clinical practice guidelines, clinical practice has been slow to change in the intensive care unit (ICU). Our aim was to identify barriers to conservative transfusion practice adherence. A mixed-methods study involving observation of prescriber (i.e., physicians, physician assistants, nurse practitioners) and bedside nurse daily bedside rounds, provider survey, and medical record abstraction was conducted in one cardiac surgical ICU (CSICU) and one surgical ICU (SICU) in an academic hospital in Baltimore, Maryland. Of 52 patient encounters observed during bedside rounds, 38 (73%) involved patients without evidence of active bleeding or cardiac ischemia. Surveys were completed by 52 (93%) of the 56 providers participating in rounds. Prescribers in the CSICU and SICU (87 and 90%, respectively) indicated the ideal pretransfusion hemoglobin (Hb) to be not more than 7 g/dL in nonbleeding and/or nonischemic patients compared to a minority of nurses (8% [p = 0.002] and 42% [p = 0.015], respectively). Prescribers and nurses in both ICUs overestimated the typical pretransfusion Hb in their units (CSICU, p < 0.001; SICU, p = 0.019). During rounds, providers infrequently explicitly discussed Hb monitoring or transfusion thresholds (33%) despite most (60%) reporting significant variation in transfusion thresholds between individual prescribers. Our study identified several provider and system barriers to evidence-based transfusion practices including knowledge differences, overly optimistic estimates of current practice, and heterogeneous transfusion practice in each ICU. Further work is necessary to develop targeted interventions to improve evidence-based RBC transfusion practices. © 2014 AABB.

Preapproval randomized controlled trials of antiepileptic drugs provide data in limited patient groups. We assessed the side effect and seizure reduction profile of tiagabine (TGB) in typical clinical practice. Investigators recorded adverse effect (AE), seizure, and assessment-of-benefit data prospectively in sequential patients treated open label with TGB. Two hundred ninety-two patients (39 children) were enrolled to be treated long term with TGB. Seizure types were focal-onset (86%), generalized-onset (12%), both focal- and generalized-onset (0.3%), and multiple associated with Lennox-Gastaut Syndrome (2%). Two hundred thirty-one received at least one dose of TGB (median = 28 mg/day) and had follow-up seizure or AE data reported. Common AEs were fatigue, dizziness, psychomotor slowing, ataxia, gastrointestinal upset, weight change, insomnia, and "others" (mostly behavioral). Serious AEs occurred in 19 patients: behavioral effects (n = 12), status epilepticus (n = 3), others (n = 3), and sudden unexplained death (n = 1). No patients experienced suicidal ideation/behavior, rash, nephrolithiasis, or organ failure. Seizure outcomes were seizure freedom (5%), ≥75% reduction (12%), ≥50% reduction (23%), and increased number of seizures (17%), or new seizure type (1%). Behavioral AEs occurred in a larger proportion of patients compared to those reported in TGB preapproval randomized controlled trials. A moderate percentage of patients had a meaningful reduction in seizure frequency. In clinical practice, TGB remains a useful antiepileptic drug. Copyright © 2013 Elsevier Inc. All rights reserved.

Patient Education and Informed Consent for Preimplantation Genetic Diagnosis: Health Literacy for Genetics and Assisted Reproductive Technology

PubMed Central

McGowan, Michelle L.; Burant, Chris; Moran, Rocio; Farrell, Ruth

2013-01-01

Introduction Innovative applications of genetic testing have emerged within the field of assisted reproductive technology through preimplantation genetic diagnosis (PGD). As in all forms of genetic testing, adequate genetic counseling and informed consent are critical. Despite the growing recognition of the role of informed consent in genetic testing, there is little data available about how this process occurs in the setting of PGD. Methods A cross sectional study of IVF clinics offering PGD in the U.S. was conducted to assess patient education and informed consent practices. Descriptive data were collected with a self-administered survey instrument. Results More than half of the clinics offering PGD required genetic counseling prior to PGD (56%). Genetic counseling was typically performed by certified genetic counselors (84 %). Less than half (37%) of the clinics required a separate informed consent process for genetic testing of embryonic cells. At a majority of those clinics requiring a separate informed consent for genetic testing (54%), informed consent for PGD and genetic testing took place as a single event before beginning IVF procedures. Conclusions The results suggest that patient education and informed consent practices for PGD have yet to be standardized. These findings warrant the establishment of professional guidelines for patient education and informed consent specific to embryonic genetic testing. PMID:19652605

Understanding and treatment of chronic abdominal pain in pediatric primary care.

Schurman, Jennifer Verrill; Kessler, Emily D; Friesen, Craig A

2014-10-01

This study examined the practices used by primary care pediatricians to assess and treat chronic abdominal pain (CAP), as an initial step in guiding clinical practice guideline (CPG) development. A survey was mailed to a random sample of office-based pediatrician members (primary care pediatricians [PCPs]) of the American Medical Association. PCPs (n = 470) provided information about the typical presentation of CAP, assessment/treatment approaches used in their own practice, their definition of a functional gastrointestinal disorder (FGID), and their familiarity with the Rome Criteria for diagnosing FGIDs. Substantial variability among PCPs was noted across all these areas. Results suggest that perceptions and practices of pediatric CAP vary widely among PCPs; no single standard of care emerged to guide development of a CPG for this population. Future research should evaluate the efficacy of specific strategies currently in use to identify potential opportunities for improving assessment and treatment of CAP in pediatric primary care. © The Author(s) 2014.

Predicting Friendship Quality in Autism Spectrum Disorders and Typical Development

PubMed Central

Solomon, Marjorie; Rogers, Sally J.

2009-01-01

The role played by social relationship variables (attachment security; mother–child relationship qualities) and social-cognitive capacities (theory of mind) was examined in both observed friendship behaviors and in children’s descriptions of friendships (age 8–12) with high functioning children with autism spectrum disorders (HFASD) (n = 44) and with typical development (TYP) (n = 38). Overall, half of the HFASD sample (54.45%) reported maternal attachment security, corroborating data from younger children with ASD. The hypothesized predictors and their interrelations had both direct and indirect effects on friendship for both groups of children, highlighting the importance of these factors in children’s friendship development and suggesting both compensatory and amplification mechanisms for friendship qualities. Practical and clinical implications are discussed for friendship support in both ASD and TYP. PMID:20039110

Legal Issues for the Medical Director

PubMed Central

2015-01-01

The nephrologist serving as medical director of a dialysis clinic must understand that the role of director is not simply an extension of being a good nephrologist. The two roles—nephrology practice and the leadership of a dialysis clinic—may be filled by a single person. However, each role contains unique tasks, requiring specific skill sets, and each role comes with inherent, associated legal risks. The medical director assumes a new level of responsibility and accountability defined by contractual obligations to the dialysis provider and by state and federal regulations. Hence, a medical director is accountable not only for providing standard-of-care treatment to his or her private practice patients dialyzed at the clinic but also for maintaining the safety of the dialysis clinic patient population and staff. Accordingly, a nephrologist serving in the role of medical director faces distinct legal risks beyond typical professional liability concerns. The medical director must also be mindful of regulatory compliance, unique avenues to licensure board complaints, and implications of careless communication habits. A thoughtful and prepared medical director can mitigate these risk exposures by understanding the sources of these challenges: contractual obligations, pertinent regulatory responsibilities, and the modern electronic communications environment.

"What constitutes a 'problem'?" Producing 'alcohol problems' through online counselling encounters.

PubMed

Savic, Michael; Ferguson, Nyssa; Manning, Victoria; Bathish, Ramez; Lubman, Dan I

2017-08-01

Typically, health policy, practice and research views alcohol and other drug (AOD) 'problems' as objective things waiting to be detected, diagnosed and treated. However, this approach to policy development and treatment downplays the role of clinical practices, tools, discourses, and systems in shaping how AOD use is constituted as a 'problem'. For instance, people might present to AOD treatment with multiple psycho-social concerns, but usually only a singular AOD-associated 'problem' is considered serviceable. As the assumed nature of 'the serviceable problem' influences what treatment responses people receive, and how they may come to be enacted as 'addicted' or 'normal' subjects, it is important to subject clinical practices of problem formulation to critical analysis. Given that the reach of AOD treatment has expanded via the online medium, in this article we examine how 'problems' are produced in online alcohol counselling encounters involving people aged 55 and over. Drawing on poststructural approaches to problematisation, we not only trace how and what 'problems' are produced, but also what effects these give rise to. We discuss three approaches to problem formulation: (1) Addiction discourses at work; (2) Moving between concerns and alcohol 'problems'; (3) Making 'problems' complex and multiple. On the basis of this analysis, we argue that online AOD counselling does not just respond to pre-existing 'AOD problems'. Rather, through the social and clinical practices of formulation at work in clinical encounters, online counselling also produces them. Thus, given a different set of circumstances, practices and relations, 'problems' might be defined or emerge differently-perhaps not as 'problems' at all or perhaps as different kinds of concerns. We conclude by highlighting the need for a critical reflexivity in AOD treatment and policy in order to open up possibilities for different ways of engaging with, and responding to, people's needs in their complexity.

Background Using an online survey, we collected data to present a picture of how clinical authorization is performed in the UK. Methods A 21-question survey was uploaded to www.surveymonkey.com , and responses were invited via the mail base of the Association for Clinical Biochemistry and Laboratory Medicine. The questionnaire examined the intensity and function of the duty biochemist role and how different types of authorization are used to handle and release results. Results Of 70 responses received, 60 were suitable for analysis. Responses were received from every region of the UK. A typical duty biochemist shift started on average at 8:50, and finished at 17:25. The mean duration was 8 h 58 min. Clinical scientists are the most abundantly represented group on duty biochemist rotas. Higher banded clinical scientists and chemical pathologists covered out-of-hours shifts. Results were handled differently depending on the level of abnormality and the requesting area. Normal results tended to be released either directly from the analyser or after technical then autoauthorization (90%). A greater preference for clinical authorization was seen for abnormal and critical results originating from outpatients (49% and 69%, respectively) or general practice (51% and 71%) than for inpatients (33% and 53%) or A&E (25% and 37%). Conclusions The handling and authorization of biochemistry results varies greatly between laboratories. The role is clearly heterogeneous in the UK. Guidance from the Association for Clinical Biochemistry and Royal College of Pathologists may help to clarify the essential roles of the duty biochemist.

Foreign exam management in practice: seamless access to foreign images and results in a regional environment.

PubMed

Nagels, Jason; MacDonald, David; Parker, David

2015-04-01

A challenge for many clinical users is that a patient may receive a diagnostic imaging (DI) service at a number of hospitals or private imaging clinics. The DI services that patients receive at other locations could be clinically relevant to current treatments, but typically, there is no seamless method for a clinical user to access longitudinal DI results for their patient. Radiologists, and other specialists that are intensive users of image data, require seamless ingestion of foreign exams into the picture archiving and communication system (PACS) to achieve full clinical value. Most commonly, a clinical user will depend on the patient to bring in a CD that contains imaging from another location. However, a number of issues can arise when using this type of solution. Firstly, a CD will not provide the clinical user with the full longitudinal record of the patient. Secondly, a CD often will not contain the report associated with the images. Finally, a CD is not seamless, due to the need to manually import the contents of the CD into the local PACS. In order to overcome these limitations, and provide clinical users with a greater benefit related to a patient's longitudinal DI history, the implementation of foreign exam management (FEM) at the local site level is required. This paper presents the experiences of FEM in practice. By leveraging industry standards and edge devices to support FEM, multiple sites with disparate PACS and radiology information system (RIS) vendors are able to seamlessly ingest foreign exams within their local PACS as if they are local exams.

[Body dysmorphic disorder].

Grau, Katharina; Fegert, Jörg Michael; Allroggen, Marc

2015-01-01

Body dysmorphic disorder (BDD) is a relatively common disorder with a point prevalence of 0.7-2.4 %. BDD is characterized by the patient's excessive concern with an imagined or slight defect in physical appearance. BDD usually begins in adolescence. Comorbidity rates and also suicidality rates are high. The course of BDD tends to be chronic. According to the present state of knowledge, cognitive-behavioral therapy and pharmacotherapy with selective serotonin reuptake inhibitors are valuable options in the therapy of BDD. The case report describes a recent case of BDD with typical clinical and therapy-related characteristics. The aim of this work is to strengthen the awareness of BDD in clinical practice of child and adolescent psychiatry, facilitating an adequate diagnosis and treatment of the affected individuals.

Bridging the clinician/researcher gap with systemic research: the case for process research, dyadic, and sequential analysis.

Oka, Megan; Whiting, Jason

2013-01-01

In Marriage and Family Therapy (MFT), as in many clinical disciplines, concern surfaces about the clinician/researcher gap. This gap includes a lack of accessible, practical research for clinicians. MFT clinical research often borrows from the medical tradition of randomized control trials, which typically use linear methods, or follow procedures distanced from "real-world" therapy. We review traditional research methods and their use in MFT and propose increased use of methods that are more systemic in nature and more applicable to MFTs: process research, dyadic data analysis, and sequential analysis. We will review current research employing these methods, as well as suggestions and directions for further research. © 2013 American Association for Marriage and Family Therapy.

Prolonged delirium misdiagnosed as a mood disorder.

PubMed

Cao, Fei; Salem, Haitham; Nagpal, Caesa; Teixeira, Antonio L

2017-01-01

Delirium can be conceptualized as an acute decline in cognitive function that typically lasts from hours to a few days. Prolonged delirium can also affect patients with multiple predisposing and/or precipitating factors. In clinical practice, prolonged delirium is often unrecognized, and can be misdiagnosed as other psychiatric disorders. We describe a case of a 59-year-old male presenting with behavioral and cognitive symptoms that was first misdiagnosed as a mood disorder in a general hospital setting. After prolonged delirium due to multiple factors was confirmed, the patient was treated accordingly with symptomatic management. He evolved with progressive improvement of his clinical status. Early diagnosis and management of prolonged delirium are important to improve patient prognosis and avoid iatrogenic measures.

Reimbursement and costs of pediatric ambulatory diabetes care by using the resource-based relative value scale: is multidisciplinary care financially viable?

PubMed

Melzer, Sanford M; Richards, Gail E; Covington, Maxine L

2004-09-01

The ambulatory care for children with diabetes mellitus (DM) within an endocrinology specialty practice typically includes services provided by a multidisciplinary team. The resource-based relative value scale (RBRVS) is increasingly used to determine payments for ambulatory services in pediatrics. It is not known to what extent resource-based practice expenses and physician work values as allocated through the RBRVS for physician and non-physician practice expenses cover the actual costs of multidisciplinary ambulatory care for children with DM. A pediatric endocrinology and diabetes clinic staffed by faculty physicians and hospital support staff in a children's hospital. Data from a faculty practice plan billing records and income and expense reports during the period from 1 July 2000 to 30 June 2001 were used to determine endocrinologist physician ambulatory productivity, revenue collection, and direct expenses (salary, benefits, billing, and professional liability (PLI)). Using the RBRVS, ambulatory care revenue was allocated between physician, PLI, and practice expenses. Applying the activity-based costing (ABC) method, activity logs were used to determine non-physician and facility practice expenses associated with endocrine (ENDO) or diabetes visits. Of the 4735 ambulatory endocrinology visits, 1420 (30%) were for DM care. Physicians generated $866,582 in gross charges. Cash collections of 52% of gross charges provided revenue of $96 per visit. Using the actual Current Procedural Terminology (CPT)-4 codes reported for these services and the RBRVS system, the revenue associated with the 13,007 total relative value units (TRVUs) produced was allocated, with 58% going to cover physician work expenses and 42% to cover non-physician practice salary, facility, and PLI costs. Allocated revenue of $40.60 per visit covered 16 and 31% of non-physician and facility practice expenses per DM and general ENDO visit, respectively. RBRVS payments ($35/RVU) covered 46% of all expenses ($76.74/RVU), including 132% of physician expenses for the time worked in the clinic ($27/RVU), and only 23% of actual incurred practice expenses ($152/TRVU). Clinical revenues in a pediatric endocrinology practice, allocated by using the RBRVS system, do cover physician expenses for the time spent working in a hospital ENDO and DM clinic, but do not closely approximate non-physician and facility practice expenses while delivering multidisciplinary care to children with DM. Using payment based on the RBRVS system, and without additional payments to compensate for increased practice expenses incurred in the delivery of multidisciplinary care, this care model may not be financially viable.

Health professionals' perceptions about their clinical performance and the influence of audit and feedback on their intentions to improve practice: a theory-based study in Dutch intensive care units.

Audit and feedback aims to guide health professionals in improving aspects of their practice that need it most. Evidence suggests that feedback fails to increase accuracy of professional perceptions about clinical performance, which likely reduces audit and feedback effectiveness. This study investigates health professionals' perceptions about their clinical performance and the influence of feedback on their intentions to change practice. We conducted an online laboratory experiment guided by Control Theory with 72 intensive care professionals from 21 units. For each of four new pain management indicators, we collected professionals' perceptions about their clinical performance; peer performance; targets; and improvement intentions before and after receiving first-time feedback. An electronic audit and feedback dashboard provided ICU's own performance, median and top 10% peer performance, and improvement recommendations. The experiment took place approximately 1 month before units enrolled into a cluster-randomised trial assessing the impact of adding a toolbox with suggested actions and materials to improve intensive care pain management. During the experiment, the toolbox was inaccessible; all participants accessed the same version of the dashboard. We analysed 288 observations. In 53.8%, intensive care professionals overestimated their clinical performance; but in only 13.5%, they underestimated it. On average, performance was overestimated by 22.9% (on a 0-100% scale). Professionals similarly overestimated peer performance, and set targets 20.3% higher than the top performance benchmarks. In 68.4% of cases, intentions to improve practice were consistent with actual gaps in performance, even before professionals had received feedback; which increased to 79.9% after receiving feedback (odds ratio, 2.41; 95% CI, 1.53 to 3.78). However, in 56.3% of cases, professionals still wanted to improve care aspects at which they were already top performers. Alternatively, in 8.3% of cases, they lacked improvement intentions because they did not consider indicators important; did not trust the data; or deemed benchmarks unrealistic. Audit and feedback helps health professionals to work on aspects for which improvement is recommended. Given the abundance of professionals' prior good improvement intentions, the limited effects typically found by audit and feedback studies are likely predominantly caused by barriers to translation of intentions into actual change in clinical practice.

Revenue-based cost assignment: a potent but hidden threat to the survival of the multispecialty medical practice.

PubMed

Cooper, Robin; Kramer, Theresa R

2010-03-01

To demonstrate detrimental effects of revenue-based cost assignment (RBCA) in clinical practice and to compare that system with activity-based costing (ABC). Four cost-allocation methods including RBCA were applied to a comprehensive ophthalmology practice using typical accounting methods. Data were obtained by a survey of practitioners or practices and/or extracted from decision support and practice management systems. Inaccuracies and distortions in reported costs were enumerated. Accounting scenario analysis was used to predict resultant provider and managerial decisions. A sampling survey was used to analyze other specialties. ABC was applied to the practice. RBCA causes procedures with higher profitability to appear less profitable and those with lower profitability to appear more profitable. The distortion in reported costs, in medical settings, is often sufficient to incentivize providers with higher profitability to exit a practice and those with lower profitability to remain in it. The departure of providers causes the residual practice profits to decline. These detrimental effects occur in many subspecialties, which suggests a national effect on health care. ABC allocation can reduce cost distortions and eliminate detrimental effects. RBCA leads to fragmentation of health care and a reduction in the profitability of multispecialty practices. Its use may slow the updating of reimbursement and help eliminate low-profitability specialties.

Gendered negotiations for research participation in community-based studies: implications for health research policy and practice

PubMed Central

Kamuya, Dorcas M; Molyneux, Catherine, S; Theobald, Sally

2017-01-01

There is a growing literature documenting the complex realities of consent processes in the field, and the negotiations and ethical dilemmas involved. Much has also been written about how gender and power shape household decision-making processes. However, these bodies of literature have rarely been brought together to inform research theory and practice in low-income settings. In this paper, qualitative research (observation, focus group discussions and interviews) were used alongside large clinical community-based studies conducted on the Kenyan Coast to explore how gender and power relations within households and communities and between fieldworkers and communities shape consent processes and interactions. This exploration is embedded in relevant literature and the implications for community-based health research policy and practice are considered. Across diverse forms of households, we observed significant consultation on whether or not to participate in research. Although men are typically described as household decision-makers, in practice, decision-making processes are often far more nuanced, with many women using their agency to control, sometimes subtly, the decisions made. Where decisions are made without adequately consulting women, many find strategies to exercise their choice, in ways that safeguard important relationships within households in the longer term. We also found that the gender of field staff who typically conduct research activities in the field, including consent processes, can influence household dynamics and decision-making processes with important implications for the science and ethics of research. It is essential that frontline field staff and their supervisors are aware of the complex and gendered realities of consent processes at household level, and their implications, and that they develop appropriate context-informed approaches that support ethical practice.

Thinking like a nurse: a research-based model of clinical judgment in nursing.

PubMed

Tanner, Christine A

2006-06-01

This article reviews the growing body of research on clinical judgment in nursing and presents an alternative model of clinical judgment based on these studies. Based on a review of nearly 200 studies, five conclusions can be drawn: (1) Clinical judgments are more influenced by what nurses bring to the situation than the objective data about the situation at hand; (2) Sound clinical judgment rests to some degree on knowing the patient and his or her typical pattern of responses, as well as an engagement with the patient and his or her concerns; (3) Clinical judgments are influenced by the context in which the situation occurs and the culture of the nursing care unit; (4) Nurses use a variety of reasoning patterns alone or in combination; and (5) Reflection on practice is often triggered by a breakdown in clinical judgment and is critical for the development of clinical knowledge and improvement in clinical reasoning. A model based on these general conclusions emphasizes the role of nurses' background, the context of the situation, and nurses' relationship with their patients as central to what nurses notice and how they interpret findings, respond, and reflect on their response.

Opioid Use in the Twenty First Century: Similarities and Differences Across National Borders

Vasilev, Georgi; Milcheva, Svetla; Vassileva, Jasmin

2016-01-01

Opinion Statement The global prevalence in the use of opiates and opioids has remained stable, though there were some unprecedented recent increases in opioid use and associated mortality and morbidity in the United States. Internationally, there is a strong tendency for consolidation of drug treatment strategies in favor of more systematic, structured and balanced approaches to regional and national drug policies. However, there are considerable differences in the scope, focus, and implementation of national drug policies and the political context is shaping drug prevention, treatment and rehabilitation efforts to an extent not typically observed in other public health domains. As a result, though in theory, there is a considerable multi-national agreement about the efficacy and effectiveness of different treatment modalities for opioid dependence, in practice, there are striking differences among different world regions and countries in the degree of implementation of these treatment modalities into clinical practice. Such discrepancies between theory and practice are observed even in high-income countries such as the United States and European Union member states, where evidence-based treatment modalities are still not well implemented into clinical practice. Despite the lack of evidence-based support for the role of detoxification as a stand-alone treatment for opioid use disorders, it appears to be the most widely used intervention for opioid use across the world.

Telephone-based mental health triage services are frontline health-care providers that operate 24/7 to facilitate access to psychiatric assessment and intervention for people requiring assistance with a mental health problem. The mental health triage clinical role is complex, and the populations triage serves are typically high risk; yet to date, no evidence-based methods have been available to assess clinician competence to practice telephone-based mental health triage. The present study reports the findings of a study that investigated the validity and usability of the Mental Health Triage Competency Assessment Tool, an evidence-based, interactive computer programme designed to assist clinicians in developing and assessing competence to practice telephone-based mental health triage. © 2015 Australian College of Mental Health Nurses Inc.

A consistent feature of many lung nodule management guidelines is the recommendation to evaluate nodule size by using diameter measurements and electronic calipers. Traditionally, the use of nodule volumetry applications has primarily been reserved for certain lung cancer screening trials rather than clinical practice. However, even before the first nodule management guidelines were published more than a decade ago, research has been ongoing into the use of nodule volumetry as a means of measuring nodule size, and this research has accelerated in recent years. This article aims to provide radiologists with an up-to-date review of the most recent literature on volumetry and volume doubling times in lung nodule management, outlining their benefits and drawbacks. A brief technical review of typical volumetry applications is also provided. © RSNA, 2017.

An emphasis on quality improvement (QI) is vital to the cost-effective provision of evidence-based health care. QI projects in gastroenterology have typically focused on endoscopy to minimize or eliminate procedure-related complications or errors. However, a significant component of gastroenterology care is based on the management of chronic disease. Patients with chronic diseases are seen in many different outpatient practices in the community and academia. In an attempt to ensure that every patient receives high-quality care, major gastrointestinal societies have published guidelines on the management of common gastrointestinal complaints. However, adherence to these guidelines varies. We discuss common outpatient gastrointestinal illnesses with established guidelines for management that could benefit from active QI projects; these would ensure a consistently high standard of care for every patient.

2018-06-01

The study assessed the clinical utility of an invented spelling tool and determined whether invented spelling with linguistic manipulation at segmental and supra-segmental levels can be used to better identify reading difficulties. We conducted linguistic manipulation by using real and nonreal words, incorporating word stress, alternating the order of consonants and vowels, and alternating the number of syllables. We recruited 60 third-grade students, of which half were typical readers and half were poor readers. The invented spelling task consistently differentiated those with reading difficulties from typical readers. It explained unique variance in conventional spelling, but not in word reading. Word stress explained unique variance in both word reading and conventional spelling, highlighting the importance of addressing phonological awareness at the supra-segmental level. Poor readers had poorer performance when spelling both real and nonreal words and demonstrated substantial difficulty in detecting word stress. Poor readers struggled with spelling words with double consonants at the beginning and ending of words, and performed worse on spelling two- and three-syllable words than typical readers. Practical implications for early identification and instruction are discussed.

Activation of tissue mast cells (MCs) and their abnormal growth and accumulation in various organs are typically found in primary MC disorders also referred to as mastocytosis. However, increasing numbers of patients are now being informed that their clinical findings are due to MC activation (MCA) that is neither associated with mastocytosis nor with a defined allergic or inflammatory reaction. In other patients with MCA, MCs appear to be clonal cells, but criteria for diagnosing mastocytosis are not met. A working conference was organized in 2010 with the aim to define criteria for diagnosing MCA and related disorders, and to propose a global unifying classification of all MC disorders and pathologic MC reactions. This classification includes three types of ‘MCA syndromes’ (MCASs), namely primary MCAS, secondary MCAS and idiopathic MCAS. MCA is now defined by robust and generally applicable criteria, including (1) typical clinical symptoms, (2) a substantial transient increase in serum total tryptase level or an increase in other MC-derived mediators, such as histamine or prostaglandin D2, or their urinary metabolites, and (3) a response of clinical symptoms to agents that attenuate the production or activities of MC mediators. These criteria should assist in the identification and diagnosis of patients with MCAS, and in avoiding misdiagnoses or overinterpretation of clinical symptoms in daily practice. Moreover, the MCAS concept should stimulate research in order to identify and exploit new molecular mechanisms and therapeutic targets. PMID:22041891

From the bench to clinical practice: understanding the challenges and uncertainties in immunogenicity testing for biopharmaceuticals

2016-01-01

Summary Unlike conventional chemical drugs where immunogenicity typically does not occur, the development of anti‐drug antibodies following treatment with biologics has led to concerns about their impact on clinical safety and efficacy. Hence the elucidation of the immunogenicity of biologics is required for drug approval by health regulatory authorities worldwide. Published ADA ‘incidence’ rates can vary greatly between same‐class products and different patient populations. Such differences are due to disparate bioanalytical methods and interpretation approaches, as well as a plethora of product‐specific and patient‐specific factors that are not fully understood. Therefore, the incidence of ADA and their association with clinical consequences cannot be generalized across products. In this context, the intent of this review article is to discuss the complex nature of ADA and key nuances of the methodologies used for immunogenicity assessments, and to dispel some fallacies and myths.

Nakamura, Yusaku

2017-07-29

Dystonia is defined as a movement disorder characterized by sustained or intermittent muscles contraction causing abnormal, often repetitive, movements, postures, or both. Dystonic movements are typically patterned and twisting, and may be tremulous. The precis diagnosis of dystonia is difficult for physicians because neurological brain imaging does not provide enough practical information. The diagnosis is depend on clinical experience of physicians. Botulinum toxin treatment is the accepted standard of care for patients with focal dystonia. Botulinum toxin treatment results in significant improvement of decreasing the symptom of dystonia. The success of treatment is dependent on muscle selection for treating involved muscles. Usually performance of botulinum toxin treatment is injected according to clinical experience of surface anatomy or clinical location method. However, the benefit of guidance of botulinum toxin treatment is improve outcome in dystonia. Injection techniques with ultra sound echogram or EMG guidance to identify dystonic muscles can be more benefit for patients.

Aggressive/attacking and helpful/emphatic/prosocial behaviors are extremely important in human relationships. Both high levels of aggression and deficits of prosociality play important role in the development and conservation of mental disorders. We review the measurement options and clinical importance of aggressive and prosocial behavior. The typical developmental pathways and the genetic and environmental background of these behaviors are presented. The clinical tools used in the measurement of aggression and prosociality are summarized in the present paper, with specific attention on questionnaires applied in Hungarian practice. The connections between diagnostic categories (conduct disorder, oppositional-defiant disorder, attention deficit and hyperactive disorder, autism spectrum disorders) and the two behaviors are evaluated. In the end, we present those additional research projects that explore the cognitive-emotional background of aggressive or prosocial behavior with clinical relevance either in the diagnosis or in the treatment of child psychiatric diseases.

We evaluated emergency physicians' (EP) current perceptions, practice, and attitudes towards evaluating stroke as a cause of dizziness among emergency department patients. We administered a survey to all EPs in a large integrated healthcare delivery system. The survey included clinical vignettes, perceived utility of historical and exam elements, attitudes about the value of and requisite post-test probability of a clinical prediction rule for dizziness. We calculated descriptive statistics and post-test probabilities for such a clinical prediction rule. The response rate was 68% (366/535). Respondents' median practice tenure was eight years (37% female, 92% emergency medicine board certified). Symptom quality and typical vascular risk factors increased suspicion for stroke as a cause of dizziness. Most respondents reported obtaining head computed tomography (CT) (74%). Nearly all respondents used and felt confident using cranial nerve and limb strength testing. A substantial minority of EPs used the Epley maneuver (49%) and HINTS (head-thrust test, gaze-evoked nystagmus, and skew deviation) testing (30%); however, few EPs reported confidence in these tests' bedside application (35% and 16%, respectively). Respondents favorably viewed applying a properly validated clinical prediction rule for assessment of immediate and 30-day stroke risk, but indicated it would have to reduce stroke risk to <0.5% to be clinically useful. EPs report relying on symptom quality, vascular risk factors, simple physical exam elements, and head CT to diagnose stroke as the cause of dizziness, but would find a validated clinical prediction rule for dizziness helpful. A clinical prediction rule would have to achieve a 0.5% post-test stroke probability for acceptability.

Clinical test responses to different orthoptic exercise regimes in typical young adults.

The relative efficiency of different eye exercise regimes is unclear, and in particular the influences of practice, placebo and the amount of effort required are rarely considered. This study measured conventional clinical measures following different regimes in typical young adults. A total of 156 asymptomatic young adults were directed to carry out eye exercises three times daily for 2 weeks. Exercises were directed at improving blur responses (accommodation), disparity responses (convergence), both in a naturalistic relationship, convergence in excess of accommodation, accommodation in excess of convergence, and a placebo regime. They were compared to two control groups, neither of which were given exercises, but the second of which were asked to make maximum effort during the second testing. Instruction set and participant effort were more effective than many exercises. Convergence exercises independent of accommodation were the most effective treatment, followed by accommodation exercises, and both regimes resulted in changes in both vergence and accommodation test responses. Exercises targeting convergence and accommodation working together were less effective than those where they were separated. Accommodation measures were prone to large instruction/effort effects and monocular accommodation facility was subject to large practice effects. Separating convergence and accommodation exercises seemed more effective than exercising both systems concurrently and suggests that stimulation of accommodation and convergence may act in an additive fashion to aid responses. Instruction/effort effects are large and should be carefully controlled if claims for the efficacy of any exercise regime are to be made. © 2014 The Authors Ophthalmic & Physiological Optics published by John Wiley & Sons Ltd on behalf of The College of Optometrists.

The Clinical Presentation of Oral Potentially Malignant Disorders.

Mccormick, Neal J; Thomson, Peter J; Carrozzo, Marco

2016-02-01

Early detection of oral cancer improves survival rates significantly, however, the incidence of oral cancer has continued to rise in the UK - between 2002-2012, it increased by more than 30%. There is currently no national screening programme for oral cancer, so undertaking a full examination of the oral mucosa during routine dental appointments is vital. Although strong evidence is still lacking, oral cancer is thought to be preceded by oral potential malignant disorders (OPMDs) or oral precancerous diseases. These mainly present as white/red lesions within the mouth and their clinical appearance can be challenging to diagnose accurately, which can lead to them being misdiagnosed as negligible problems. Dentists must keep up to date with OPMDs detection and ensure they are capable of correctly recognising lesions that carry a potential risk. This paper aims to provide a brief overview on OPMDs, highlighting potentially malignant disorders as they may present to the practitioner, showing their typical clinical appearance, and suggesting differential diagnosis and clinical management in dental practice.

The assessment and treatment of prosodic disorders and neurological theories of prosody.

Diehl, Joshua J; Paul, Rhea

2009-08-01

In this article, we comment on specific aspects of Peppé (Peppé, 2009). In particular, we address the assessment and treatment of prosody in clinical settings and discuss current theory on neurological models of prosody. We argue that in order for prosodic assessment instruments and treatment programs to be clinical effective, we need assessment instruments that: (1) have a representative normative comparison sample and strong psychometric properties; (2) are based on empirical information regarding the typical sequence of prosodic acquisition and are sensitive to developmental change; (3) meaningfully subcategorize various aspects of prosody; (4) use tasks that have ecological validity; and (5) have clinical properties, such as length and ease of administration, that allow them to become part of standard language assessment batteries. In addition, we argue that current theories of prosody processing in the brain are moving toward network models that involve multiple brain areas and are crucially dependent on cortical communication. The implications of these observations for future research and clinical practice are outlined.

Turning the Waiting Room into a Classroom: Weekly Classes Using a Vegan or a Portion-Controlled Eating Plan Improve Diabetes Control in a Randomized Translational Study.

In research settings, plant-based (vegan) eating plans improve diabetes management, typically reducing weight, glycemia, and low-density lipoprotein (LDL) cholesterol concentrations to a greater extent than has been shown with portion-controlled eating plans. The study aimed to test whether similar benefits could be found using weekly nutrition classes in a typical endocrinology practice, hypothesizing that a vegan eating plan would improve glycemic control, weight, lipid concentrations, blood pressure, and renal function and would do so more effectively than a portion-controlled eating plan. In a 20-week trial, participants were randomly assigned to a low-fat vegan or portion-controlled eating plan. Individuals with type 2 diabetes treated in a single endocrinology practice in Washington, DC, participated (45 starters, 40 completers). Participants attended weekly after-hours classes in the office waiting room. The vegan plan excluded animal products and added oils and favored low-glycemic index foods. The portion-controlled plan included energy intake limits for weight loss (typically a deficit of 500 calories/day) and provided guidance on portion sizes. Body weight, hemoglobin A1c (HbA1c), plasma lipids, urinary albumin, and blood pressure were measured. For normally distributed data, t tests were used; for skewed outcomes, rank-based approaches were implemented (Wilcoxon signed-rank test for within-group changes, Wilcoxon two-sample test for between-group comparisons, and exact Hodges-Lehmann estimation to estimate effect sizes). Although participants were in generally good metabolic control at baseline, body weight, HbA1c, and LDL cholesterol improved significantly within each group, with no significant differences between the two eating plans (weight: -6.3 kg vegan, -4.4 kg portion-controlled, between-group P=0.10; HbA1c, -0.40 percentage point in both groups, P=0.68; LDL cholesterol -11.9 mg/dL vegan, -12.7 mg/dL portion-controlled, P=0.89). Mean urinary albumin was normal at baseline and did not meaningfully change. Blood pressure changes were not significant. Weekly classes, integrated into a clinical practice and using either a low-fat vegan or portion-controlled eating plan, led to clinical improvements in individuals with type 2 diabetes.

Physician training and standards for medical licensure differ widely across the globe. The medical education process in the United States (US) typically involves a minimum of 11 years of formal training and multiple standardized examinations between graduating from secondary school and becoming an attending physician with full medical licensure. Students in the US traditionally enter a 4-year medical school after completing an undergraduate bachelor's degree, in contrast to most other countries where medical training begins after graduation from high school. Medical school seniors planning to practice medicine in the US must complete postgraduate clinical training, referred to as residency, within the specialty of their choosing. The duration of residency varies depending on specialty, typically lasting between 3 and 7 years. For subspecialty fields, additional clinical training is often required in the form of a fellowship. Many experts have called for changes in the medical education system to shorten medical training in the US, and reforms are ongoing in some institutions. However, physician education in the US generally remains a progression from undergraduate premedical coursework to 4 years of medical school, followed by residency training with an optional subspecialty fellowship.

Social communication skills are critical in the health professions. The aim of this study was to measure and identify professional practice predictors of social communication skills of practicing chiropractors. The study population was derived from a group of doctors of chiropractic who participated in a practice-based research program. Participating chiropractors agreed to complete a survey detailing the chiropractor's sex, years in practice, practice type, size of the practice community, typical weekly practice volume, and an instrument to measure skills of social communication. Regression analysis was applied to identify associations between independent variables and responses to the social skills instrument. Results suggested that selected characteristics of clinical practice may be associated with clinician's social skills of communication. The weekly volume of patients to the practice emerged as a salient explanatory factor of overall social communication skills and as a factor individually for dimensions of social expressivity and social control. The practice arrangement (solo vs group) proved important in terms of respondent emotional control scores. Similarly, the solo vs group practice variable was associated with higher levels of emotional sensitivity; however, this association was mediated by the sex of the doctor of chiropractic; men reported lower levels of emotional sensitivity than women. The findings of this study suggest associations between dimensions of social communication skills, practice characteristics, practice arrangements, and sex that may inform the efforts of educators as they endeavor to better prepare health professionals for practice in a wide spectrum of settings.

Driving CT developments the last mile: case examples of successful and somewhat less successful translations into clinical practice

2017-03-01

CT technology has advanced rapidly in recent years, yet not all innovations translate readily into clinical practice. Technology advances must meet certain key requirements to make it into routine use: They must provide a well-defined clinical benefit. They must be easy to use and integrate readily into existing workflows, or better still, further streamline these workflows. These requirements heavily favor fully integrated or automated solutions that remove the human factor and provide a reproducible output independent of operator skill level. Further, to achieve these aims, collaboration with the ultimate end users is needed as early as possible in the development cycle, not just at the point of product testing. Technology innovators are encouraged to engage such collaborators even at early stages of feature or product definition. This manuscript highlights these concepts through exploration of challenging areas in CT imaging in an Emergency Department setting. Technique optimization for pulmonary embolus CT is described as an example of successful integration of multiple advances in radiation dose reduction and imaging speed. The typical workflow of a trauma "pan-scan" (incorporating scans from head through pelvis) is described to highlight workflow challenges and opportunities for improvement. Finally, Dual Energy CT is discussed to highlight the undeniable clinical value of the material characterization it provides, yet also its surprisingly slow integration into routine use beyond early adopters.

Deep brain stimulation (DBS) of the subthalamic nucleus improves the motor symptoms of Parkinson's disease, but may produce a worsening of speech and language performance at rates and amplitudes typically selected in clinical practice. The possibility that these dissociated effects might be modulated by selective stimulation of left and right STN has never been systematically investigated. To address this issue, we analyzed motor, speech and language functions of 12 patients implanted with bilateral stimulators configured for optimal motor responses. Behavioral responses were quantified under four stimulator conditions: bilateral DBS, right-only DBS, left-only DBS and no DBS. Under bilateral and left-only DBS conditions, our results exhibited a significant improvement in motor symptoms but worsening of speech and language. These findings contribute to the growing body of literature demonstrating that bilateral STN DBS compromises speech and language function and suggests that these negative effects may be principally due to left-sided stimulation. These findings may have practical clinical consequences, suggesting that clinicians might optimize motor, speech and language functions by carefully adjusting left- and right-sided stimulation parameters.

Traditional Chinese medicine (TCM), the ancient medicine popular in China and surrounding areas, has been recognized as a typical representative of complementary and alternative medicine. Over long period in clinical practice, especially the progress in basic research, data on the effectiveness and beneficial contribution of TCM herbs to public health and disease control have been accumulated while the quality of the evidence is generally poor. The most common clinical practice of TCM herbs is herb combination called formula which consists of several types of medicinal herbs or minerals, which is quite different from modern medicine. Definitely, tens of hundreds of compounds could be identified in even a small formula. With the regained enthusiasm on natural products based new drug R&D, the proposed multi-target drug discovery strategy, the booming of -omics technologies, and the implementation of ambitious plan of TCM modernization in China, attempts have been made to fill the gap between TCM herbs and modern drugs.

Deciding about fast and slow decisions.

Croskerry, Pat; Petrie, David A; Reilly, James B; Tait, Gordon

2014-02-01

Two reports in this issue address the important topic of clinical decision making. Dual process theory has emerged as the dominant model for understanding the complex processes that underlie human decision making. This theory distinguishes between the reflexive, autonomous processes that characterize intuitive decision making and the deliberate reasoning of an analytical approach. In this commentary, the authors address the polarization of viewpoints that has developed around the relative merits of the two systems. Although intuitive processes are typically fast and analytical processes slow, speed alone does not distinguish them. In any event, the majority of decisions in clinical medicine are not dependent on very short response times. What does appear relevant to diagnostic ease and accuracy is the degree to which the symptoms of the disease being diagnosed are characteristic ones. There are also concerns around some methodological issues related to research design in this area of enquiry. Reductionist approaches that attempt to isolate dependent variables may create such artificial experimental conditions that both external and ecological validity are sacrificed. Clinical decision making is a complex process with many independent (and interdependent) variables that need to be separated out in a discrete fashion and then reflected on in real time to preserve the fidelity of clinical practice. With these caveats in mind, the authors believe that research in this area should promote a better understanding of clinical practice and teaching by focusing less on the deficiencies of intuitive and analytical systems and more on their adaptive strengths.

Implementing evidence-based practices in an emergency department: contradictions exposed when prioritising a flow culture.

Kirk, Jeanette W; Nilsen, Per

2016-02-01

An emergency department is typically a place of high activity where practitioners care for unanticipated presentations, which yields a flow culture so that actions that secure available beds are prioritised by the practitioners. How does the flow culture in an emergency department influence nurses' use of a research-based clinical guideline and a nutrition screening routine. Ethnographic fieldwork was carried out over three months. The first author followed nurses, medical secretaries and doctors in the emergency department. Data were also collected by means of semi-structured interviews. An activity system analysis, as described in the Cultural Historical Activity Theory, was conducted to identify various contradictions that could exist between different parts of the activity system. The main contradiction identified was that guidelines and screening routines provided a flow stop. Four associated contradictions were identified: insufficient time to implement guidelines; guilty conscience due to perceived nonadherence to evidence-based practices; newcomers having different priorities; and conflicting views of what constituted being a professional. We found that research-supported guidelines and screening routines were not used if they were perceived to stop the patient flow, suggesting that the practice was not fully evidence based. © 2016 The Authors.

Addressing phenoconversion: the Achilles' heel of personalized medicine

PubMed Central

Shah, Rashmi R; Smith, Robert L

2015-01-01

Phenoconversion is a phenomenon that converts genotypic extensive metabolizers (EMs) into phenotypic poor metabolizers (PMs) of drugs, thereby modifying their clinical response to that of genotypic PMs. Phenoconversion, usually resulting from nongenetic extrinsic factors, has a significant impact on the analysis and interpretation of genotype-focused clinical outcome association studies and personalizing therapy in routine clinical practice. The high phenotypic variability or genotype–phenotype mismatch, frequently observed due to phenoconversion within the genotypic EM population, means that the real number of phenotypic PM subjects may be greater than predicted from their genotype alone, because many genotypic EMs would be phenotypically PMs. If the phenoconverted population with genotype–phenotype mismatch, most extensively studied for CYP2D6, is as large as the evidence suggests, there is a real risk that genotype-focused association studies, typically correlating only the genotype with clinical outcomes, may miss clinically strong pharmacogenetic associations, thus compromising any potential for advancing the prospects of personalized medicine. This review focuses primarily on co-medication-induced phenoconversion and discusses potential approaches to rectify some of the current shortcomings. It advocates routine phenotyping of subjects in genotype-focused association studies and proposes a new nomenclature to categorize study populations. Even with strong and reliable data associating patients' genotypes with clinical outcome(s), there are problems clinically in applying this knowledge into routine pharmacotherapy because of potential genotype–phenotype mismatch. Drug-induced phenoconversion during routine clinical practice remains a major public health issue. Therefore, the principal challenges facing personalized medicine, which need to be addressed, include identification of the following factors: (i) drugs that are susceptible to phenoconversion; (ii) co-medications that can cause phenoconversion; and (iii) dosage amendments that need to be applied during and following phenoconversion.

Background High prevalence rates of posttraumatic stress disorder (PTSD) in active military and veterans present a treatment challenge. Many PTSD studies have demonstrated the efficacy and safety of Emotional Freedom Techniques (EFT). Objectives To develop clinical best practice guidelines for the use of EFT to treat PTSD, on the basis of the published literature, practitioner experience, and typical case histories. Methods We surveyed 448 EFT practitioners to gather information on their experiences with PTSD treatment. This included their demographic profiles, prior training, professional settings, use of assessments, and PTSD treatment practices. We used their responses, with the research evidence base, to formulate clinical guidelines applying the “stepped care” treatment model used by the United Kingdom’s National Institute for Health and Clinical Excellence. Results Most practitioners (63%) reported that even complex PTSD can be remediated in 10 or fewer EFT sessions. Some 65% of practitioners found that more than 60% of PTSD clients are fully rehabilitated, and 89% stated that less than 10% of clients make little or no progress. Practitioners combined EFT with a wide variety of other approaches, especially cognitive therapy. Practitioner responses, evidence from the literature, and the results of a meta-analysis were aggregated into a proposed clinical guideline. Conclusion We recommend a stepped care model, with 5 EFT therapy sessions for subclinical PTSD and 10 sessions for clinical PTSD, in addition to group therapy, online self-help resources, and social support. Clients who fail to respond should be referred for appropriate further care. PMID:28678690

Patient-reported outcomes to initiate a provider-patient dialog for the management of hip and knee osteoarthritis.

Although many treatment guidelines exist for hip and knee osteoarthritis (OA), uptake in clinical practice is typically low. Valid patient-reported outcome measures (PROs) that can be easily used in the clinic could aid implementation and evaluation of treatment recommendations, and the tracking of symptoms and function over time. This project responded to a 2012 Call to Action of the Chronic Osteoarthritis Management Initiative of the United States Bone and Joint Initiative; we aimed to develop a tiered list of recommended PROs that could be feasibly applied in common clinical settings, across four domains of pain, function, fatigue, and sleep. PROs were identified through a focused literature review. Clinicians and researchers with OA expertise evaluated each measure' feasibility for use in routine clinical practice, followed by meaningfulness in assessing OA outcomes. Eligible PROs were categorized by domain and ranked into Tiers One (very brief measures for initial use in clinical settings), Two (brief measures with more in-depth assessment), and Three (most detailed assessment). Total PROs identified were 172 for pain, 160 for function, 55 for fatigue, and 60 for sleep. Of these, 9 pain, 7 function, 7 fatigue, and 8 sleep PROs were ranked into one of three tiers. This three-tiered list of recommended PROs provides a basis for tools to systematically track outcomes, facilitate provider-patient dialog, and guide treatment for hip or knee OA. Research is needed to test the utility and feasibility of systematic implementation of these measures in primary care and specialty clinical settings. Copyright © 2015 Elsevier Inc.

This present study is a report of an interview study exploring personal views on participating in group clinical supervision among mental health nursing staff members who do not participate in supervision. There is a paucity of empirical research on resistance to supervision, which has traditionally been theorized as a supervisee's maladaptive coping with anxiety in the supervision process. The aim of the present study was to examine resistance to group clinical supervision by interviewing nurses who did not participate in supervision. In 2015, we conducted semistructured interviews with 24 Danish mental health nursing staff members who had been observed not to participate in supervision in two periods of 3 months. Interviews were audio-recorded and subjected to discourse analysis. We constructed two discursive positions taken by the informants: (i) 'forced non-participation', where an informant was in favour of supervision, but presented practical reasons for not participating; and (ii) 'deliberate rejection', where an informant intentionally chose to not to participate in supervision. Furthermore, we described two typical themes drawn upon by informants in their positioning: 'difficulties related to participating in supervision' and 'limited need for and benefits from supervision'. The findings indicated that group clinical supervision extended a space for group discussion that generated or accentuated anxiety because of already-existing conflicts and a fundamental lack of trust between group members. Many informants perceived group clinical supervision as an unacceptable intrusion, which could indicate a need for developing more acceptable types of post-registration clinical education and reflective practice for this group. © 2017 Australian College of Mental Health Nurses Inc.

Clinical practice improvement carried out in a quality assurance framework relies on routinely collected data using clinical indicators. Herein we describe the development, minimum training requirements, and inter-rater agreement of indicators that were used in an Australian multi-site evaluation of the effectiveness of early psychosis (EP) teams. Surveys of clinician opinion and face-to-face consensus-building meetings were used to select and conceptually define indicators. Operationalization of definitions was achieved by iterative refinement until clinicians could be quickly trained to code indicators reliably. Calculation of percentage agreement with expert consensus coding was based on ratings of paper-based clinical vignettes embedded in a 2-h clinician training package. Consensually agreed upon conceptual definitions for seven clinical indicators judged most relevant to evaluating EP teams were operationalized for ease-of-training. Brief training enabled typical clinicians to code indicators with acceptable percentage agreement (60% to 86%). For indicators of suicide risk, psychosocial function, and family functioning this level of agreement was only possible with less precise 'broad range' expert consensus scores. Estimated kappa values indicated fair to good inter-rater reliability (kappa > 0.65). Inspection of contingency tables (coding category by health service) and modal scores across services suggested consistent, unbiased coding across services. Clinicians are able to agree upon what information is essential to routinely evaluate clinical practice. Simple indicators of this information can be designed and coding rules can be reliably applied to written vignettes after brief training. The real world feasibility of the indicators remains to be tested in field trials.

Clinical decision support systems (CDSSs) are gaining popularity as tools that assist physicians in optimizing medical care. These systems typically comply with evidence-based medicine and are designed with input from domain experts. Nonetheless, deviations from CDSS recommendations are abundant across a broad spectrum of disorders, raising the question as to why this phenomenon exists. Here, we analyze this gap in adherence to a clinical guidelines-based CDSS by examining the physician treatment decisions for 1329 adult soft tissue sarcoma patients in northern Italy using patient-specific parameters. Dubbing this analysis "CareGap", we find that deviations correlate strongly with certain disease features such as local versus metastatic clinical presentation. We also notice that deviations from the guideline-based CDSS suggestions occur more frequently for patients with shorter survival time. Such observations can direct physicians' attention to distinct patient cohorts that are prone to higher deviation levels from clinical practice guidelines. This illustrates the value of CareGap analysis in assessing quality of care for subsets of patients within a larger pathology.

Three upper limb robotic devices for stroke rehabilitation: a review and clinical perspective.

PubMed

Bishop, Lauri; Stein, Joel

2013-01-01

Stroke is a leading cause of disability worldwide. Many survivors of stroke remain with residual disabilities, even years later. Advances in technology have led to the development of a variety of robotic devices for use in rehabilitation. The integration of robotics in the delivery of neurorehabilitation is promising, but still not widely used in clinical settings. The aim of this review is to discuss the general design of three typical upper limb robotic devices, and examine the practical considerations for their use in a clinical environment. Each device is described, the available clinical literature is reviewed and a clinical perspective is given on the usefulness of these robotic devices in rehabilitation of this population. Current literature supports the use of robotics in the clinical environment. However, claims that robotic therapy is more effective than traditional treatment is not substantially supported. The majority of clinical trials reported are small, and lack the use of a control group for comparison treatment. The use of robotics in stroke rehabilitation is still a relatively new treatment platform, and still evolving. As technological advances are made, there is much potential for growth in this field.

Functional tics, also called psychogenic tics or pseudo-tics, are difficult to diagnose because of the lack of diagnostic criteria and their clinical similarities to organic tics. The aim of the present study was to report a case series of patients with documented functional tics and to describe their clinical characteristics, risk factors and psychiatric comorbidity. Also clinical tips are suggested which might help the differential diagnosis in clinical practice. Eleven patients (mean age at onset 37.2, SD 13.5; three females) were included with a documented or clinically established diagnosis of functional tics, according to consultant neurologists who have specific expertise in functional movement disorders or in tic disorders. Adult onset, absent family history of tics, inability to suppress the movements, lack of premonitory sensations, absence of pali-, echo- and copro-phenomena, presence of blocking tics, the lack of the typical rostrocaudal tic distribution and the coexistence of other functional movement disorders were common in our patients. Our data suggest that functional tics can be differentiated from organic tics on clinical grounds, although it is also accepted that this distinction can be difficult in certain cases. Clinical clues from history and examination described here might help to identify patients with functional tics. © 2014 EAN.

Environmental Chemical Assessment in Clinical Practice: Unveiling the Elephant in the Room

PubMed Central

Bijlsma, Nicole; Cohen, Marc M.

2016-01-01

A growing body of evidence suggests chemicals present in air, water, soil, food, building materials and household products are toxicants that contribute to the many chronic diseases typically seen in routine medical practice. Yet, despite calls from numerous organisations to provide clinicians with more training and awareness in environmental health, there are multiple barriers to the clinical assessment of toxic environmental exposures. Recent developments in the fields of systems biology, innovative breakthroughs in biomedical research encompassing the “-omics” fields, and advances in mobile sensing, peer-to-peer networks and big data, provide tools that future clinicians can use to assess environmental chemical exposures in their patients. There is also a need for concerted action at all levels, including actions by individual patients, clinicians, medical educators, regulators, government and non-government organisations, corporations and the wider civil society, to understand the “exposome” and minimise the extent of toxic exposures on current and future generations. Clinical environmental chemical risk assessment may provide a bridge between multiple disciplines that uses new technologies to herald in a new era in personalised medicine that unites clinicians, patients and civil society in the quest to understand and master the links between the environment and human health.

Determining if an older adult can make and execute decisions to live safely at home: a capacity assessment and intervention model

Determining an older adult’s capacity to live safely and independently in the community presents a serious and complicated challenge to the health care system. Evaluating one’s ability to make and execute decisions regarding safe and independent living incorporates clinical assessments, bioethical considerations, and often legal declarations of capacity. Capacity assessments usually result in life changes for patients and their families, including a caregiver managing some everyday tasks, placement outside of the home, and even legal guardianship. The process of determining capacity and recommending intervention is often inefficient and highly variable in most cases. Physicians are rarely trained to conduct capacity assessments and assessment methods are heterogeneous. An interdisciplinary team of clinicians developed the capacity assessment and intervention (CAI) model at a community outpatient geriatrics clinic to address these critical gaps. This report follows one patient through the entire CAI model, describing processes for a typical case. It then examines two additional case reports that highlight common challenges in capacity assessment. The CAI model uses assessment methods common to geriatrics clinical practice and conducts assessments and interventions in a standardized fashion. Reliance on common, validated measures increases generalizability of the model across geriatrics practice settings and patient populations. PMID:19481271

[Dissociative identity disorder or schizophrenia?].

2010-01-01

We present a case of dissociative identity disorder in which Schneiderian first rank symptoms were present besides of various states of consciousness. Thus the diagnosis of schizophrenia had to be considered. Formally, the symptoms met ICD-10 criteria for schizophrenia. However, taking into account the lack of formal thought disorder and of negative symptoms as well as a typical history of severe and prolonged traumatisation, we did not diagnose a co-morbid schizophrenic disorder. There is good evidence for the existence of psychotic symptoms among patients with dissociative disorders. However, in clinical practice this differential diagnosis is rarely considered.

Surrogate biochemical markers: precise measurement for strategic drug and biologics development.

1995-05-01

More efficient drug and biologics development is necessary for future success of pharmaceutical and biotechnology companies. One way to achieve this objective is to use rationally selected surrogate markers to improve the early decision-making process. Using typical clinical chemistry methods to measure biochemical markers may not ensure adequate precision and reproducibility. In contrast, using analytical methods that meet good laboratory practices along with rational selection and validation of biochemical markers can give those who use them a competitive advantage over those who do not by providing meaningful data for earlier decision making.

Unlike traditional clinical trial research, Comparative Effectiveness Research seeks to determine what is 'best' for a typical patient when deciding between effective options used in daily practice - a therapy, diagnostic test, or course of action. There is a clear need for Comparative Effectiveness Research in Inflammatory Bowel Disease, a point emphasized by the Institute of Medicine and supported by governmental agencies and escalating funding. This review highlights the rationale and support for Comparative Effectiveness Research, provides examples of Comparative Effectiveness Research in Inflammatory Bowel Disease, and outlines current and future focus for Comparative Effectiveness Research in Inflammatory Bowel Disease.

Facilitating behavioral learning and habit change in voice therapy--theoretic premises and practical strategies.

PubMed

Iwarsson, Jenny

2015-12-01

A typical goal of voice therapy is a behavioral change in the patient's everyday speech. The SLP's plan for voice therapy should therefore optimally include strategies for automatization. The aim of the present study was to identify and describe factors that promote behavioral learning and habit change in voice behavior and have the potential to affect patient compliance and thus therapy outcome. Research literature from the areas of motor and behavioral learning, habit formation, and habit change was consulted. Also, specific elements from personal experience of clinical voice therapy are described and discussed from a learning theory perspective. Nine factors that seem to be relevant to facilitate behavioral learning and habit change in voice therapy are presented, together with related practical strategies and theoretical underpinnings. These are: 1) Cue-altering; 2) Attention exercises; 3) Repetition; 4) Cognitive activation; 5) Negative practice; 6) Inhibition through interruption; 7) Decomposing complex behavior; 8) The 'each time-every time' principle; and 9) Successive implementation of automaticity.

Similarities and differences in parenting practices of children (Mage = 10; range 8-13 years) with traumatic brain injury (TBI) and socially-typical controls were examined. In addition, parenting practices were examined as moderators between injury group status (TBI or socially-typical) and social adjustment in the peer group. Mothers completed assessments of parenting practices; children's peers reported about children's social adjustment. The mothers of children with TBI reported significantly lower levels of nurturance and significantly higher levels of restrictiveness than mothers of socially-typical children. In addition, mothers’ nurturance moderated the relation between injury group and peer rejection, such that children with TBI were more rejected by classmates compared to their socially-typical peers at low levels of maternal nurturance. The findings are interpreted as supporting the important role parents play in the development of children with a history of TBI, as well as the implications for family-level interventions.

Psychological treatments for posttraumatic stress disorder: recommendations for the clinician based on a review of the literature.

This article reviews available research data supporting the use of psychotherapy in the treatment of posttraumatic stress disorder (PTSD). The authors highlight how this evidence might inform clinical choices in treating PTSD, as well as demonstrating how assumptions based on gaps in the available literature may be misleading. The authors first discuss findings concerning a number of interventions that are commonly used in the treatment of trauma victims or patients with PTSD: critical incident stress debriefing, psychoeducation, exposure therapy, eye movement desensitization reprocessing, stress inoculation therapy, trauma management therapy, cognitive therapy, psychodynamic psychotherapy, and hypnotherapy. They also discuss a number of treatment strategies that have recently been studied in PTSD, including imagery rehearsal, memory structure intervention, interpersonal psychotherapy, and dialectical behavior therapy. PTSD is associated with significant symptomatic morbidity, although desired outcomes in clinical practice are typically related more to reduction in social, interpersonal, and occupational impairment. The most methodologically robust studies, which have typically examined cognitive or behavioral treatments, indicate that psychotherapy helps to relieve symptom severity; however, there is no consistent information about whether these interventions are helpful in improving other domains of impairment and associated disability, even though these problems are often the greatest concern to patients. Nor does the available evidence indicate when, and for whom, various psychotherapeutic interventions should be provided, or whether different modalities of treatment can and should be combined, or sequentially offered, as is often done in specialized treatment programs. Clinicians should keep these issues in mind in reviewing the literature on current (and future) clinical research. Unfortunately, the current evidence base on psychotherapy for PTSD gives only limited guidance concerning clinical choices in managing PTSD. The authors therefore provide some clinical guidelines based on the literature for clinicians treating patients with PTSD.

Introduction We evaluated emergency physicians’ (EP) current perceptions, practice, and attitudes towards evaluating stroke as a cause of dizziness among emergency department patients. Methods We administered a survey to all EPs in a large integrated healthcare delivery system. The survey included clinical vignettes, perceived utility of historical and exam elements, attitudes about the value of and requisite post-test probability of a clinical prediction rule for dizziness. We calculated descriptive statistics and post-test probabilities for such a clinical prediction rule. Results The response rate was 68% (366/535). Respondents’ median practice tenure was eight years (37% female, 92% emergency medicine board certified). Symptom quality and typical vascular risk factors increased suspicion for stroke as a cause of dizziness. Most respondents reported obtaining head computed tomography (CT) (74%). Nearly all respondents used and felt confident using cranial nerve and limb strength testing. A substantial minority of EPs used the Epley maneuver (49%) and HINTS (head-thrust test, gaze-evoked nystagmus, and skew deviation) testing (30%); however, few EPs reported confidence in these tests’ bedside application (35% and 16%, respectively). Respondents favorably viewed applying a properly validated clinical prediction rule for assessment of immediate and 30-day stroke risk, but indicated it would have to reduce stroke risk to <0.5% to be clinically useful. Conclusion EPs report relying on symptom quality, vascular risk factors, simple physical exam elements, and head CT to diagnose stroke as the cause of dizziness, but would find a validated clinical prediction rule for dizziness helpful. A clinical prediction rule would have to achieve a 0.5% post-test stroke probability for acceptability. PMID:26587108

This study determined which clinical factors influence Canadian primary care physicians' management decisions in cases of female partner abuse. We used a cross-sectional survey design and randomly sampled (n = 2,014) English-speaking Canadian physicians with a primary interest in family or general practice who were practicing in any of the 12 provinces and territories in Canada and who were active in private practice and registered to prescribe. Respondents completed a questionnaire that required them to score management decision plans in response to case scenarios illustrating typical office-based situations that might involve domestic violence. The response rate was 50.7% (n = 1,022). Using forward stepwise regression analysis, the strongest predictor of whether a physician endorsed a management plan in response to violence was whether the woman acknowledged or revealed the abuse. Male physicians were more likely than females to endorse talking with the suspected abuser if he was known to them, regardless of the quality of this patient-physician relationship with the abuser. Decisions about whether to deal with the abuse or the selection of a management plan are not dependent on the severity of the physical abuse and the emotional consequences. Whether a woman acknowledges or reveals the abuse, as well as whether both the male and female patients are in the physician's practice, are predictive of whether a physician's response to a case scenario involves dealing with spousal abuse and how he/she will address it.

Background Clinical guidelines recommend against routine prostate specific antigen (PSA) screening in older men and those with lower life expectancies. We examined providers’ decision-making regarding discontinuing PSA screening. Methods We administered a survey of primary providers from a large, university-affiliated primary care practice. Providers were asked about their current screening practices, factors that influence their decision to discontinue screening, and barriers to discontinuing screening. Bivariate and multivariable logistic regression analyses were used to examine whether taking age and/or life expectancy into account and barriers to discontinuing were associated with clinician characteristics and practice styles. Results 88.7% of providers participated in the survey (125 out of 141). Over half (59.3%) took both age and life expectancy into account whereas 12.2% did not consider either in their decisions to discontinue PSA screening. Providers varied with the age they typically stop screening and majority (66.4%) report difficulty in assessing life expectancy. Taking patient age and life expectancy into account was not associated with provider characteristics or practice styles. The most frequently cited barriers to discontinuing PSA screening were patient expectation (74.4%) and time constraints (66.4%). Black providers were significantly less likely than non-black providers to endorse barriers related to time constraints and clinical uncertainty, though these results are limited by the small sample size of black providers. Conclusion Though age and life expectancy often figure prominently in decisions to employ screening, providers face multiple barriers to discontinue PSA routine screening, PMID:22517310

MODULAR ANALYTICS (Roche Diagnostics) (MODULAR ANALYTICS, Elecsys and Cobas Integra are trademarks of a member of the Roche Group) represents a new approach to automation for the clinical chemistry laboratory. It consists of a control unit, a core unit with a bidirectional multitrack rack transportation system, and three distinct kinds of analytical modules: an ISE module, a P800 module (44 photometric tests, throughput of up to 800 tests/h), and a D2400 module (16 photometric tests, throughput up to 2400 tests/h). MODULAR ANALYTICS allows customised configurations for various laboratory workloads. The performance and practicability of MODULAR ANALYTICS were evaluated in an international multicentre study at 16 sites. Studies included precision, accuracy, analytical range, carry-over, and workflow assessment. More than 700 000 results were obtained during the course of the study. Median between-day CVs were typically less than 3% for clinical chemistries and less than 6% for homogeneous immunoassays. Median recoveries for nearly all standardised reference materials were within 5% of assigned values. Method comparisons versus current existing routine instrumentation were clinically acceptable in all cases. During the workflow studies, the work from three to four single workstations was transferred to MODULAR ANALYTICS, which offered over 100 possible methods, with reduction in sample splitting, handling errors, and turnaround time. Typical sample processing time on MODULAR ANALYTICS was less than 30 minutes, an improvement from the current laboratory systems. By combining multiple analytic units in flexible ways, MODULAR ANALYTICS met diverse laboratory needs and offered improvement in workflow over current laboratory situations. It increased overall efficiency while maintaining (or improving) quality.

Incubating the research independence of a medical scientist training program graduate: a case study.

Physician-scientists play a critical role in discovering new biological knowledge and translating findings into medical practices that can improve clinical outcomes. Collectively, the National Institutes of Health (NIH) and its affiliated Medical Scientist Training Programs (MSTPs) invest upwards of $500,000 to fully train each of the 900+ MD/PhD students enrolled in these programs. Nevertheless, graduates face the challenges of navigating fragmented intervals of clinical training and research engagement, reinitiating research upon completing their residencies, managing financial pressures, and competing for funding following what is typically four or more years of research inactivity. Together, these barriers contribute to the high attrition rate of MSTP graduates from research careers. The authors designed and implemented (2009-2014), for a single trainee, an alternative postgraduate training model characterized by early research engagement, strategic mentoring, unyoked clinical and research milestones, and dedicated financial support. The pilot training experiment was so successful that the trainee secured an NIH project grant and completed his transition to research independence 3.5 years after starting the experimental training schedule-nearly 9 years earlier (based on age) than is typical for MD/PhDs transitioning from mentored to independent research. This success has demonstrated that unyoking research engagement from conventional calendar-based clinical training milestones is a feasible, effective means of incubating research independence in MSTP graduates. The authors encourage the design and application of similar unconventional approaches that interweave residency training with ongoing research activity for appropriate candidates, especially in subspecialties with increased MSTP graduate enrollment.

2010-12-01

To determine the current policies and practices of Society for Pediatric Radiology (SPR) members regarding the evaluation of pediatric patients with suspected pulmonary embolism (PE) with an emphasis on use of computed tomography pulmonary angiography (CTPA). Institutional review board exemption was granted for this study. Surveys were mailed electronically to the 1575 members of the SPR representing 416 institutions. Information gathered included the existence of written policies, the imaging study of choice for suspected PE, routine acquisition of chest radiographs before CTPA, currently used CTPA techniques, modifications of protocols for radiation dose reduction, typical DLP (dose-length-product) for CTPA, and estimated annual frequency of performing CTPA for evaluating PE in children. Survey items pertaining to policies and practices were compared between practice settings and populations using chi-square analysis. One hundred and sixty members representing 118 institutions responded, which resulted in a response rate of 28% (118/416), on an institutional basis. Of these 118 respondents, 104 (88%) perform CTPA in children with clinical suspicion of PE. Of the 104 respondents who perform CTPA, 26 (25%) have a written policy for CTPA, 93 (89%) perform CTPA as the first study choice, and 67 (64%) routinely obtain chest radiographs before CTPA. The most commonly used CTPA techniques in children with clinical suspicion of PE include intravenous contrast amount of 2 mL/kg, mechanical injection of intravenous contrast, and tailored bolus tracking method for CTPA scan initiation by observing the Hounsfield units of contrast in the central pulmonary artery on the monitoring scan. Sixty respondents (58%) modify CTPA imaging protocols for evaluating PE in children in order to decrease radiation dose. The two most common modifications for radiation dose reduction were reduced mAs in 41 (68%) and automatic exposure control in 38 (63%). The majority of respondents (88%) did not know the typical DLP for a 20-kg child during CTPA study performed to evaluate for PE. A significantly greater percentage of radiation dose-reduction techniques are performed within academic institutions compared with private institutions (P = .03). Most survey respondents perform CTPA as the study of choice for evaluating PE in children, but there is considerable variability in their policies and practices. Respondents from academic medical centers are more likely to employ radiation dose-reduction techniques for CTPA than those in private practice settings. Copyright © 2010 AUR.

Should fertility clinics divest themselves of pornography?

PubMed

Murphy, Timothy F

2016-12-01

Some commentators object to the way in which fertility clinics make pornography available to men as an aid to masturbation when those men produce sperm for evaluation, storage or IVF. These objections typically rely on claims that pornography is generally harmful to women, unnecessary and dissociates sexual acts from conception. In light of these objections, certain commentators want fertility clinics to divest themselves of pornography, but these objections to pornography are not morally convincing. In general, pornography can have psychological value to men masturbating 'on demand' in clinical contexts. Not all erotica must, either, work to the disadvantage of women in its means of production or social effects. Moreover, the sexuality expressed in masturbation has a value of its own, and conception apart from sexual intercourse is morally defensible on its own. Divestment from pornography would do little to constrain the putative harms of pornography because clinics consume only a fractional amount of the total amount of pornography available. The provision of pornography is a defensible clinical practice, even if it is not absolutely necessary to all men in producing a sperm sample important to their fertility or their interests in donating gametes.

Health-Related Quality of Life after Pediatric Mild Traumatic Brain Injury/Concussion: A Systematic Review.

Fineblit, Samuel; Selci, Erin; Loewen, Hal; Ellis, Michael; Russell, Kelly

2016-09-01

Health-related quality of life (HRQOL) is an emerging method to quantify the consequences of pediatric mild traumatic brain injury (mTBI)/concussion in both clinical practice and research. However, to utilize HRQOL measurements to their full potential in the context of mTBI/concussion recovery, a better understanding of the typical course of HRQOL after these injuries is needed. The objective of this study was to summarize current knowledge on HRQOL after pediatric mTBI/concussion and identify areas in need of further research. The following databases from their earliest date of coverage through June 1, 2015 were used: MEDLINE(®), PubMed, Embase, Scopus, Cumulative Index to Nursing and Allied Health Literature (CINAHL), SPORTDiscus, Cochrane Central Register of Controlled Trials (CENTRAL), Physiotherapy Evidence Database (PEDro), and Child Development and Adolescent Studies (CDAS). Studies must have examined and reported HRQOL in a pediatric population after mTBI/concussion, using a validated HRQOL measurement tool. Eight of 1660 records identified ultimately met inclusion criteria. Comprehensive data were extracted and checked by a second reviewer for accuracy and completeness. There appears to be a small but important subgroup of patients who experience poor HRQOL outcomes up to a year or longer post-injury. Potential predictors of poor HRQOL include older age, lower socioeconomic status, or a history of headaches or trouble sleeping. Differing definitions of mTBI precluded meta-analysis. HRQOL represents an important outcome measure in mTBI/concussion clinical practice and research. The evidence shows that a small but important proportion of patients have diminished HRQOL up to a year or longer post-injury. Further study on this topic is warranted to determine the typical longitudinal progression of HRQOL after pediatric concussion.

A preliminary audit of orders for computed tomography was performed to evaluate the typical performance of interns ordering radiologic examinations. According to the audit, the interns showed only minimal improvement after 8 months of work experience. The online radiology ordering module (ROM) program included baseline assessment of student performance (part I), online learning with the ROM (part II), and follow-up assessment of performance with simulated ordering with the ROM (part III). A curriculum blueprint determined the content of the ROM program, with an emphasis on practical issues, including provision of logistic information, clinical details, and safety-related information. Appropriate standards were developed by a committee of experts, and detailed scoring systems were devised for assessment. The ROM program was successful in addressing practical issues in a simulated setting. In the part I assessment, the mean score for noting contraindications for contrast media was 24%; this score increased to 59% in the part III assessment (P = .004). Similarly, notification of methicillin-resistant Staphylococcus aureus status and pregnancy status and provision of referring physician contact information improved significantly. The quality of the clinical notes was stable, with good initial scores. Part III testing showed overall improvement, with the mean score increasing from 61% to 76% (P < .0001). In general, medical students lack the core knowledge that is needed for good-quality ordering of radiology services, and the experience typically afforded to interns does not address this lack of knowledge. The ROM program was a successful intervention that resulted in statistically significant improvements in the quality of radiologic examination orders, particularly with regard to logistic and radiation safety issues.

A case of urticarial vasculitis (UV) is presented. The pathogenesis, clinical characteristics, diagnosis, and management of this disease are reviewed, followed by clinical pearls and pitfalls for the practicing allergist (Venzor J, et al., Urticarial vasculitis, Clin Rev Allergy Immunol 23:201-216, 2002). The lesions in UV typically lasts > 24 hours in a fixed location, resolves with residual hyperpigmentation, and may or may not be pruritic. In contrast, standard urticaria lesions persist < 24 hours, leave no trace, and is always pruritic (Black AK, Urticarial vasculitis, Clin Dermatol 17:565-569, 1999). Since urticarial vasculitis is characterized by a variety of cutaneous, systemic, and serological features, different names of this disorder exist in the literature (Wisnieski JJ, Urticarial vasculitis, Curr Opin Rheumatol 12:24-31, 2000). A biopsy of an active lesion remains the gold standard for the diagnosis of urticarial vasculitis.

Dental students in programs around the world typically pass preclinical courses before entering the clinic and working on actual patients. Since fixed prosthodontics is a preclinical course that requires a great deal of effort, students may experience a substantial amount of stress that may affect their self-confidence and/or clinical performance. In this study, an instructional video CD (VCD) and study guide depicting the step-by-step procedures involved in a metal-ceramic tooth preparation and provisional crown fabrication was prepared. Students at the Faculty of Dentistry, Tehran University of Medical Sciences, Tehran, Iran, were divided randomly into two groups. Group A students trained as usual with live patients, and Group B students were given a copy of the VCD and study guide following a lecture. The students in Group B were encouraged to read the study guide and watch the VCD after live demonstrations. Then, both groups practiced individually on mannequins. At the end of the course, the students completed a sixteen-item questionnaire about their stress level, self-confidence, and knowledge base. The results showed that the students exposed to the extra media performed significantly better on some practical phases, e.g., laboratory procedures. A moderate, insignificant correlation was detected between exposure to media and decreasing the students' stress and self-esteem. We concluded that supplementary teaching aids such as a VCD and study guide may improve the clinical performance of dental students to some extent, but the live demonstration is still preferred by students.

To assess the impact of the electronic health record (EHR) on cost (i.e., payments to providers) and process measures of quality of care. Retrospective before-after-study-control. From the database of a large managed care organization (MCO), we obtained the claims of patients from four community physician practices that implemented the EHR and from about 50 comparison practices without the EHR in the same counties. The diverse patient and practice populations were chosen to be a sample more representative of typical private practices than has previously been studied. For four chronic conditions, we used commercially-available software to analyze cost per episode over a year and the rate of adherence to clinical guidelines as a measure of quality. The implementation of the EHR had a modest positive impact on the quality measure of guideline adherence for hypertension and hyperlipidemia, but no significant impact for diabetes and coronary artery disease. No measurable impact on the short-term cost per episode was found. Discussions with the study practices revealed that the timing and comprehensiveness of EHR implementation varied across practices, creating an intervention variable that was heterogeneous. Guideline adherence increased across practices without EHRs and slightly faster in practices with EHRs. Measuring the impact of EHRs on cost per episode was challenging, because of the difficulty of completely capturing the long-term episodic costs of a chronic condition. Few practices associated with the study MCO had implemented EHRs in any form, much less utilizing standardized protocols.

Objectives Tackling the harm associated with acute kidney injury (AKI) is a global priority. In England, a national computerised AKI algorithm is being introduced across the National Health Service (NHS) to drive this change. The study sought to maximise its clinical utility and minimise the potential for burden on clinicians and patients in primary care. Design An appropriateness ratings evaluation using the RAND/UCLA Appropriateness Method. Setting Clinical scenarios were developed to test the timeliness in (1) communication of AKI warning stage test results from clinical pathology services to primary care, and (2) primary care clinician response to an AKI warning stage test result. Participants A 10-person panel was purposively sampled with representation from clinical biochemistry, acute and emergency medicine and general practice. General practitioners (GPs) represented typical practice in relation to rural and urban practice, out of hours care, GP commissioning and those interested in reducing the impact of medicalisation and ‘overdiagnosis’. Results There was agreement that delivery of AKI warning stage test results through interruptive methods of communication (ie, telephone) from laboratories to primary care was the appropriate next step for patients with an AKI warning stage 3 test result. In the context of acute illness, waiting up to 72 hours to respond to an AKI warning stage test result was deemed an inappropriate action in 62 out of the 65 (94.5%) cases. There was agreement that a clinician response was required within 6 hours, or less, in 39 out of 40 (97.5%) clinical cases relating AKI warning stage test results in the presence of moderate hyperkalaemia. Conclusions The study has informed national guidance to support a timely and calibrated response to AKI warning stage test results for adults in primary care. Further research is needed to support effective implementation, with a view to examine the effect on health outcomes and costs. PMID:27729353

Objectives To analyse patterns and characteristics of pharmaceutical industry sponsorship of events for Australian health professionals and to understand the implications of recent changes in transparency provisions that no longer require reporting of payments for food and beverages. Design Cross-sectional analysis. Participants and setting 301 publicly available company transparency reports downloaded from the website of Medicines Australia, the pharmaceutical industry trade association, covering the period from October 2011 to September 2015. Results Forty-two companies sponsored 116 845 events for health professionals, on average 608 per week with 30 attendees per event. Events typically included a broad range of health professionals: 82.0% included medical doctors, including specialists and primary care doctors, and 38.3% trainees. Oncology, surgery and endocrinology were the most frequent clinical areas of focus. Most events (64.2%) were held in a clinical setting. The median cost per event was $A263 (IQR $A153–1195) and over 90% included food and beverages. Conclusions Over this 4-year period, industry-sponsored events were widespread and pharmaceutical companies maintained a high frequency of contact with health professionals. Most events were held in clinical settings, suggesting a pervasive commercial presence in everyday clinical practice. Food and beverages, known to be associated with changes to prescribing practice, were almost always provided. New Australian transparency provisions explicitly exclude meals from the reporting requirements; thus, a large proportion of potentially influential payments from pharmaceutical companies to health professionals will disappear from public view.

Mobile health clinics provide an alternative portal into the healthcare system for the medically disenfranchised, that is, people who are underinsured, uninsured or who are otherwise outside of mainstream healthcare due to issues of trust, language, immigration status or simply location. Mobile health clinics as providers of last resort are an essential component of the healthcare safety net providing prevention, screening, and appropriate triage into mainstream services. Despite the face value of providing services to underserved populations, a focused analysis of the relative value of the mobile health clinic model has not been elucidated. The question that the return on investment algorithm has been designed to answer is: can the value of the services provided by mobile health programs be quantified in terms of quality adjusted life years saved and estimated emergency department expenditures avoided? Using a sample mobile health clinic and published research that quantifies health outcomes, we developed and tested an algorithm to calculate the return on investment of a typical broad-service mobile health clinic: the relative value of mobile health clinic services = annual projected emergency department costs avoided + value of potential life years saved from the services provided. Return on investment ratio = the relative value of the mobile health clinic services/annual cost to run the mobile health clinic. Based on service data provided by The Family Van for 2008 we calculated the annual cost savings from preventing emergency room visits, $3,125,668 plus the relative value of providing 7 of the top 25 priority prevention services during the same period, US$17,780,000 for a total annual value of $20,339,968. Given that the annual cost to run the program was $567,700, the calculated return on investment of The Family Van was 36:1. By using published data that quantify the value of prevention practices and the value of preventing unnecessary use of emergency departments, an empirical method was developed to determine the value of a typical mobile health clinic. The Family Van, a mobile health clinic that has been serving the medically disenfranchised of Boston for 16 years, was evaluated accordingly and found to have return on investment of $36 for every $1 invested in the program.

How to Appropriately Extrapolate Costs and Utilities in Cost-Effectiveness Analysis.

2017-08-01

Costs and utilities are key inputs into any cost-effectiveness analysis. Their estimates are typically derived from individual patient-level data collected as part of clinical studies the follow-up duration of which is often too short to allow a robust quantification of the likely costs and benefits a technology will yield over the patient's entire lifetime. In the absence of long-term data, some form of temporal extrapolation-to project short-term evidence over a longer time horizon-is required. Temporal extrapolation inevitably involves assumptions regarding the behaviour of the quantities of interest beyond the time horizon supported by the clinical evidence. Unfortunately, the implications for decisions made on the basis of evidence derived following this practice and the degree of uncertainty surrounding the validity of any assumptions made are often not fully appreciated. The issue is compounded by the absence of methodological guidance concerning the extrapolation of non-time-to-event outcomes such as costs and utilities. This paper considers current approaches to predict long-term costs and utilities, highlights some of the challenges with the existing methods, and provides recommendations for future applications. It finds that, typically, economic evaluation models employ a simplistic approach to temporal extrapolation of costs and utilities. For instance, their parameters (e.g. mean) are typically assumed to be homogeneous with respect to both time and patients' characteristics. Furthermore, costs and utilities have often been modelled to follow the dynamics of the associated time-to-event outcomes. However, cost and utility estimates may be more nuanced, and it is important to ensure extrapolation is carried out appropriately for these parameters.

Enterotoxigenic Escherichia coli strains are highly prevalent in Ugandan piggeries but disease outbreaks are masked by antibiotic prophylaxis.

Post-weaning diarrhea (PWD) caused by enterotoxigenic Escherichia coli (ETEC) is an important disease of newly weaned piglets. ETEC strains commonly express F4 and/or F18 fimbriae that attach to carbohydrate receptors present on the intestinal epithelium during colonization. The disease status in the Ugandan piggeries had previously not been studied. In this cross-sectional sero-survey and clinical outbreak monitoring, we found very high sero-prevalence levels of both anti-F4 (70.5%) and anti-F18 (73.7%) antibodies, despite limited cases of clinical outbreaks. Strains isolated from these cases were typically F18(+) ETEC. High antibiotic resistance and multi-drug resistance were characteristics of the isolates, with highest resistance level of over 95% to commonly used antibiotics such as penicillin and tetracycline. We conclude that ETEC infections are widely spread on farms in Central Uganda but clinical disease outbreaks were masked by the management practices on these farms, like the use of extensive antibiotic prophylaxis.

Medical therapeutics: from induction to scientific evolution.

PubMed

Nunes, José Pedro Lopes

2013-01-01

The field of medical therapeutics may be characterized as having suffered major scientific evolution in the last decades. The publication of landmark studies has been important enough to produce shifts in patient care. However, the scientific evolution in this field does not necessarily imply a progressively greater degree of certitude. In fact, it is not uncommon for new knowledge, when reflected in clinical practice, to weaken previous knowledge. In medical therapeutics, strict inductive reasoning implies the existence of empirical intervention data, typically clinical trial data. In many instances, however, such data does not exist-leaving room for a mixture of inductive and "pseudo-deductive" reasoning. It is often necessary to establish treatment on the basis of incomplete and inconclusive information, more so when the clinical situation is grave, but when no valid information exists, no treatment may be an option. In many instances, the rule "I wish not to impose on others" has superseded the concept "Do not impose on others what you yourself do not desire."

The mental health field has seen a trend in recent years of the increased use of information technology, including mobile phones, tablets, and laptop computers, to facilitate clinical treatment delivery to individual patients and for record keeping. However, little attention has been paid to ensuring that electronic communication with patients is private and secure. This is despite potentially deleterious consequences of a data breach, which are reported in the news media very frequently in modern times. In this article, we present typical security concerns associated with using technology in clinical services or research. We also discuss enhancing the privacy and security of electronic communication with clinical patients and research participants. We offer practical, easy-to-use software application solutions for clinicians and researchers to secure patient communication and records. We discuss such issues as using encrypted wireless networks, secure e-mail, encrypted messaging and videoconferencing, privacy on social networks, and others. © Copyright 2015 Physicians Postgraduate Press, Inc.

Uveitis associated with juvenile idiopathic arthritis (JIA) typically involves the anterior chamber segment, follows an indolent chronic course, and presents a high rate of uveitic complications and a worse outcome as compared to other aetiologies of uveitis. Disease assessment, treatment, and outcome measures have not been standardized. Collaboration between pediatric rheumatologists and ophthalmologists is critical for effective management and prevention of morbidity, impaired vision, and irreparable visual loss. Although the Standardization of Uveitis Nomenclature Working Group recommendations have been a great advance to help clinicians to improve consistency in grading and reporting data, difficulties arise at the time of deciding the best treatment approach in the individual patient in routine daily practice. For this reason, recommendations for a systematized control and treatment strategies according to clinical characteristics and disease severity in children with JIA-related uveitis were developed by a panel of experts with special interest in uveitis associated with JIA. A clinical management algorithm organized in a stepwise regimen is here presented.

Practice facilitation can help family physicians adopt evidence-based guidelines. However, many practices struggle to effectively implement practice changes that result in meaningful improvement. Building on our previous research, we examined the barriers to and enablers of implementation perceived by practice facilitators (PF) in helping practices to adopt the Improved Delivery of Cardiovascular Care (IDOCC) program, which took place at 84 primary care practices in Ottawa, Canada between April 2008 and March 2012. We conducted a qualitative analysis of PFs' narrative reports using a multiple case study design. We used a combined purposeful sampling approach to identify cases that 1) reflected experiences typical of the broader sample and 2) presented sufficient breadth of experience from each project step and family practice model. Sampling continued until data saturation was reached. Team members conducted a qualitative analysis of reports using an open and axial coding style and a constant comparative approach. Barriers and enablers were divided into five constructs: structural, organizational, provider, patient, and innovation. Narratives from 13 practice sites were reviewed. A total of 8 barriers and 11 enablers were consistently identified across practices. Barriers were most commonly reported at the organizational (n = 3) and structural level, (n = 2) while enablers were most common at the innovation level (n = 6). While physicians responded positively to PFs' presence and largely supported their recommendations for practice change, organizational and structural aspects such as lack of time, minimal staff engagement, and provider reimbursement remained too great for practices to successfully implement practice-level changes.

Widespread application of clinical natural language processing (NLP) systems requires taking existing NLP systems and adapting them to diverse and heterogeneous settings. We describe the challenges faced and lessons learned in adapting an existing NLP system for measuring colonoscopy quality. Colonoscopy and pathology reports from 4 settings during 2013-2015, varying by geographic location, practice type, compensation structure, and electronic health record. Though successful, adaptation required considerably more time and effort than anticipated. Typical NLP challenges in assembling corpora, diverse report structures, and idiosyncratic linguistic content were greatly magnified. Strategies for addressing adaptation challenges include assessing site-specific diversity, setting realistic timelines, leveraging local electronic health record expertise, and undertaking extensive iterative development. More research is needed on how to make it easier to adapt NLP systems to new clinical settings. A key challenge in widespread application of NLP is adapting existing systems to new clinical settings. © The Author 2017.

Is tapentadol different from classical opioids? A review of the evidence

PubMed Central

Langford, Richard M; Knaggs, Roger; Farquhar-Smith, Paul; Dickenson, Anthony H

2016-01-01

Tapentadol is a single molecule able to deliver analgesia by two distinct mechanisms, a feature which differentiates it from many other analgesics. Pre-clinical data demonstrate two mechanisms of action: mu-opioid receptor agonist activity and noradrenaline re-uptake inhibition. From these, one may predict that tapentadol would be applicable across a broad spectrum of pain from nociceptive to neuropathic. The evidence in animal models suggests that norepinephrine re-uptake inhibition (NRI) is a key mechanism and may even predominate over opioid actions in chronic (and especially neuropathic) pain states, reinforcing that tapentadol is different to classical opioids and may, therefore, be an a priori choice for the treatment of neuropathic and mixed pain. The clinical studies and subsequent practice experience and surveillance support the concept of opioid and non-opioid mechanisms of action. The reduced incidence of some of the typical opioid-induced side effects, compared to equianalgesic doses of classical opioids, supports the hypothesis that tapentadol analgesia is only partially mediated by opioid agonist mechanisms. Both the pre-clinical and clinical profiles appear to be differentiated from those of classical opioids. PMID:27867511

Inflammation may be involved in the pathophysiology of schizophrenia. However, few cross-sectional or longitudinal studies have examined changes in biomarker expression to evaluate diagnostic and prognostic efficacy in acute-stage schizophrenia. We compared serum inflammatory biomarker concentrations in 87 patients with acute-stage schizophrenia on admission to 105 age-, sex-, and body mass index (BMI)-matched healthy controls. The measured biomarkers were soluble tumor necrosis factor receptor 1 (sTNFR1) and adiponectin, which are associated with inflammatory responses, and pigment epithelium-derived factor (PEDF), which has anti-inflammatory properties. We then investigated biomarker concentrations and associations with clinical factors in 213 patients (including 42 medication-free patients) and 110 unmatched healthy controls to model conditions typical of clinical practice. Clinical symptoms were assessed using the Brief Psychiatric Rating Scale and Global Assessment of Function. In 121 patients, biomarker levels and clinical status were evaluated at both admission and discharge. Serum sTNFR1 was significantly higher in patients with acute-stage schizophrenia compared to matched controls while no significant group differences were observed for the other markers. Serum sTNFR1 was also significantly higher in the 213 patients compared to unmatched controls. The 42 unmedicated patients had significantly lower PEDF levels compared to controls. Between admission and discharge, sTNFR1 levels decreased significantly; however, biomarker changes did not correlate with clinical symptoms. The discriminant accuracy of sTNFR1 was 93.2% between controls and patients, showing no symptom improvement during care. Inflammation and a low-level anti-inflammatory state may be involved in both schizophrenia pathogenesis and acute-stage onset. High serum sTNFR1 in the acute stage could be a useful prognostic biomarker for treatment response in clinical practice. Copyright © 2017 Elsevier Inc. All rights reserved.

Wound-healing outcomes applying standardized protocols have typically been measured within controlled clinical trials, not natural settings. Standardized protocols of wound care have been validated for clinical use, creating an opportunity to measure the resulting outcomes. Wound-healing outcomes were explored during clinical use of standardized validated protocols of care based on patient and wound assessments. This was a prospective multicenter study of wound-healing outcomes management in real-world clinical practice. Healing outcomes from March 26 to October 31, 2001, were recorded on patients in 3 long-term care facilities, 1 long-term acute care hospital, and 12 home care agencies for wounds selected by staff to receive care based on computer-generated validated wound care algorithms. After diagnosis, wound dimensions and status were assessed using a tool adapted from the Pressure Sore Status Toolfor use on all wounds. Wound, ostomy, and continence nursing professionals accessed consistent protocols of care, via telemedicine in home care or paper forms in long-term care. A physician entered assessments into a desktop computer in the wound clinic. Based on evidence that healing proceeds faster with fewer infections in environments without gauze, the protocols generally avoided gauze dressings. Most of the 767 wounds selected to receive the standardized-protocols of care were stage III-IV pressure ulcers (n = 373; mean healing time 62 days) or full-thickness venous ulcers (n = 124; mean healing time 57 days). Partial-thickness wounds healed faster than same-etiology full-thickness wounds. These results provide benchmarks for natural-setting healing outcomes and help to define and address wound care challenges. Outcomes primarily using nongauze protocols of care matched or surpassed best previously published results on similar wounds using gauze-based protocols of care, including protocols applying gauze impregnated with growth factors or other agents.

The long-term follow-up (LTFU) team at the Seattle Cancer Care Alliance uses telemedicine to diagnose and treat post-transplantation complications in hematopoietic cell transplantation (HCT) survivors. Photos are often requested via the telemedicine service to aid in diagnosis, but they are typically of poor quality, making them unusable. This project offered bachelor of science in nursing students, partnered with a comprehensive cancer center, the opportunity to participate in an evidence-based practice project to improve detection and management of chronic graft-versus-host disease (cGVHD) in patients after HCT. Students partnered with RNs to develop instructional tools using multiple evidence sources. A brochure and video were developed. Providing these instructional tools to those in the LTFU program improved patient outcomes for managing cGVHD through telemedicine. This partnership provided an opportunity for mutual learning and improved clinical practice.

Private for-profit health care providers are prominent in the health system of the Philippines. To examine the practices of the private practitioners in Malabon, Metropolitan Manila, Philippines, concerning diagnosis and treatment of tuberculosis (TB). Forty-five private practitioners of Malabon who treat adult TB patients were interviewed. For diagnosis, most private practitioners relied on the clinical presentation and result of an X-ray. Only 13% of the respondents routinely also asked for sputum examination. Ninety-six percent used X-ray as a tool to monitor treatment. Sixty percent of the respondents prescribed a regimen consisting of isoniazid, rifampicin, pyrazinamide, and ethambutol. Except for rifampicin, over-dosage was common. For re-treatment cases, none prescribed the WHO-recommended re-treatment regimen. The private practitioners perceived the main reasons for patient non-adherence to be the patients' lack of finances to buy drugs and patients' perceived well being after a certain period of treatment. Patients' lack of money was seen as the main obstacle to compliance. The only case holding mechanism mentioned was occasional clinic appointments of the TB patients. Private practices for diagnosis and treatment of TB typically deviate from guidelines. The quality of care among private practitioners needs improvement. Innovative strategies are required.

Stakeholder-Driven Quality Improvement: A Compelling Force for Clinical Practice Guidelines.

PubMed

Rosenfeld, Richard M; Wyer, Peter C

2018-01-01

Clinical practice guideline development should be driven by rigorous methodology, but what is less clear is where quality improvement enters the process: should it be a priority-guiding force, or should it enter only after recommendations are formulated? We argue for a stakeholder-driven approach to guideline development, with an overriding goal of quality improvement based on stakeholder perceptions of needs, uncertainties, and knowledge gaps. In contrast, the widely used topic-driven approach, which often makes recommendations based only on randomized controlled trials, is driven by epidemiologic purity and evidence rigor, with quality improvement a downstream consideration. The advantages of a stakeholder-driven versus a topic-driven approach are highlighted by comparisons of guidelines for otitis media with effusion, thyroid nodules, sepsis, and acute bacterial rhinosinusitis. These comparisons show that stakeholder-driven guidelines are more likely to address the quality improvement needs and pressing concerns of clinicians and patients, including understudied populations and patients with multiple chronic conditions. Conversely, a topic-driven approach often addresses "typical" patients, based on research that may not reflect the needs of high-risk groups excluded from studies because of ethical issues or a desire for purity of research design.

Tumor, lymph node, and metastasis (TNM) classification of lung cancer is typically performed with the TNM staging system, as recommended by the Union Internationale Contre le Cancer (UICC), the American Joint Committee on Cancer (AJCC), and the International Association for the Study of Lung Cancer (IASLC). Radiologic examinations for TNM staging of lung cancer patients include computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography with 2-[fluorine-18] fluoro-2-deoxy-D-glucose (FDG-PET), and FDG-PET combined with CT (FDG-PET/CT) and are used for pretherapeutic assessments. Recent technical advances in MR systems, application of fast and parallel imaging and/or introduction of new MR techniques, and utilization of contrast media have markedly improved the diagnostic utility of MRI in this setting. In addition, FDG-PET can be combined or fused with MRI (PET/MRI) for clinical practice. This review article will focus on these recent advances in MRI as well as on PET/MRI for lung cancer staging, in addition to a discussion of their potential and limitations for routine clinical practice in comparison with other modalities such as CT, FDG-PET, and PET/CT.

Implications of Pharmacogenomics to the Management of IBS.

PubMed

Camilleri, Michael

2018-04-27

The objectives are to review the role of pharmacogenomics in drug metabolism of medications typically used in patients with irritable bowel syndrome (IBS) focusing predominantly on cytochrome P450 metabolism. Other aims are to provide examples of genetic variation of receptors or intermediary pathways that are targets for IBS drugs and to critically appraise the situations where precision medicine is impacting health in IBS. Pharmacogenomics impacts both pharmacokinetics and pharmacodynamics. Although large clinical trials have not incorporated testing for genetic variations that could impact the efficacy of medications in IBS, there are therapeutic advantages to inclusion of pharmacogenomics testing for individual patients, as has been demonstrated particularly in the treatment with central neuromodulators in psychiatry practice. Clinical practice in IBS is moving in the same direction with the aid of commercially available tests focused on drug metabolism. Specific mechanisms leading to pathophysiology of IBS are still poorly characterized, relative to diseases such as cancer and inflammatory bowel disease, and, therefore, pharmacogenomics related to drug pharmacodynamics is still in its infancy and requires extensive future research. With increased attention to pharmacogenomics affecting drug metabolism, it is anticipated that pharmacogenomics will impact care of IBS. Copyright © 2018 AGA Institute. Published by Elsevier Inc.

Best practices research identifies and disseminates effective clinical strategies developed and refined by clinicians for their practices. As opposed to the content of health care, medical students and residents are typically not trained in the process of its provision. This paper illustrates a best practices approach to development of a Web-based classroom data collection method to improve medication management in attention deficit hyperactivity disorder (ADHD). 1) To increase Primary Care Physician (PCP) awareness of the process of best practices research, and; 2) to highlight the use of the World Wide Web as a tool for integration of care of children with ADHD. Based on the review of a large national study in ADHD, the key ingredients for the best pharmacotherapy practices were identified. The lessons from the literature were adapted for local practice using the framework and steps for best practices outlined by Mold and Gregory. A conceptual model of managing information provided by parents/caregivers and teachers to PCPs was developed. Several steps were identified, including Web-based classroom behavioral data collection by a care manager and feedback reports to PCPs from a child psychiatrist based on the data collected. This model is currently being tested. Our preliminary experience suggests that a best practices approach has potential applications to a variety of primary care settings in South Dakota. We encourage PCPs to consider best practice strategies for their own practices. The practice-based research network (Rush Net) being developed by the Center for Rural Health Improvement of the University of South Dakota School of Medicine's Department of Family Medicine can be helpful in this regard.

Lyme disease is the most common tick-borne infection in the Northern hemisphere. Cardiac manifestations of Lyme disease typically include variable atrioventricular nodal block and rarely structural heart pathology. The incidence of Lyme carditis may be underestimated based on current reporting practices of confirmed cases. This case of a 59-year-old man with Lyme carditis demonstrates the unique presentation of widespread conduction system disease, mitral regurgitation, and suspected ischemic disease. Through clinical data, electrocardiograms, and cardiac imaging, we show the progression, and resolution, of a variety of cardiac symptoms attributable to infection with Lyme.

2013-09-01

The process of monitoring treatment outcome, also known as "client feedback," is increasingly becoming a recommended practice for psychotherapy. One concern, however, is how to integrate such a process into the work that psychotherapists typically do. Three clinical examples are presented, illustrating how a client feedback system can be used in conjunction with a specific theoretical framework, interpersonal process therapy (Teyber, 2006). The examples highlight that client feedback not only can be of minimal disruption to the psychotherapy process, but may also offer the potential to augment a clinician's approach to helping. Theoretical and research support are provided for each example. 2013 APA, all rights reserved

Kyphosis and Kyphoscoliosis Associated with Congenital Malformations of the Thoracic Vertebral Bodies in Dogs.

Dewey, Curtis W; Davies, Emma; Bouma, Jennifer L

2016-03-01

Congenital malformations of the thoracic vertebral bodies are commonly encountered in veterinary practice. These anomalies are prevalent in juvenile and adult small-breed dogs. These anomalous vertebrae typically result in various degrees of kyphosis and scoliosis in the region of the abnormality. They are thought to occur following developmental errors during embryonic or fetal vertebral segmentation and ossification; most are incidental. This article focuses on those anomalies of the thoracic vertebral bodies that lead to clinical signs of neurologic dysfunction. Based on a limited number of reported cases, the prognosis for surgically managed dogs with thoracic vertebral body abnormalities is favorable. Published by Elsevier Inc.

Improving stroke transitions: Development and implementation of a social work case management intervention.

Hughes, Anne K; Woodward, Amanda T; Fritz, Michele C; Reeves, Mathew J

2018-02-01

Strokes impact over 800,000 people every year. Stroke care typically begins with inpatient care and then continues across an array of healthcare settings. These transitions are difficult for patients and caregivers, with psychosocial needs going unmet. Our team developed a case management intervention for acute stroke patients and their caregivers aimed at improving stroke transitions. The intervention focusses on four aspects of a successful care transition: support, preparedness, identifying and addressing unmet needs, and stroke education. This paper describes the development and implementation of this program, and is an example of the synergy created between neuroscience and clinical practice.

An accountability server for health care information systems.

PubMed

Kowalski, S

1994-02-01

The paper starts off by first briefly discussing the necessary ethical, legal and administrative/management controls that are required before the mechanisms of accountability controls can be implemented in automated clinical patient record systems. After these social aspects are discussed the technical aspects of the ALS are outlined. The security concepts of the ECMA framework are reviewed and used to explain the technical design of the ALS. A walk-through of the server in a typical patient record transaction is used to explain the operations of the server. The paper concludes with a general discussion of the usefulness of accountability mechanisms in making security in health care information work in practice.

Word-initial /r/-clusters in Swedish speaking children with typical versus protracted phonological development.

2018-01-01

The present study investigated word-initial (WI) /r/-clusters in Central Swedish-speaking children with and without protracted phonological development (PPD). Data for WI singleton /r/ and singleton and cluster /l/ served as comparisons. Participants were twelve 4-year-olds with PPD and twelve age- and gender-matched typically developing (TD) controls. Native speakers audio-recorded and transcribed 109 target single words using a Swedish phonology test with 12 WI C+/r/-clusters and three WI CC+/r/-clusters. The results showed significantly higher match scores for the TD children, a lower match proportion for the /r/ targets and for singletons compared with clusters, and differences in mismatch patterns between the groups. There were no matches for /r/-cluster targets in the PPD group, with all children except two in that group showing deletions for both /r/-cluster types. The differences in mismatch proportions and types between the PPD group and controls suggests new directions for future clinical practice.

Background Users of typical antipsychotics have increased risk of serious ventricular arrhythmias and sudden cardiac death. However, less is known regarding the cardiac safety of the atypical antipsychotic drugs, which have largely replaced the older agents in clinical practice. Methods We calculated the adjusted incidence of sudden cardiac death among current users of antipsychotics in a retrospective cohort of Tennessee Medicaid enrollees. The primary analysis included 44,218 and 46,089 baseline users of single typical and atypical drugs, respectively, and 186,600 matched nonuser controls. To assess residual confounding related to antipsychotic indication, we performed a secondary analysis of antipsychotic users with no baseline diagnosis of schizophrenia or related psychoses, propensity-score matched with nonusers. Results Current users of both typical and atypical antipsychotics had greater rates of sudden cardiac death than did nonusers of any antipsychotic, with adjusted incidence-rate ratios (IRRs) of 2.00 (95% CI, 1.69–2.35) and 2.27 (1.89–2.73), respectively. Former antipsychotic users had no significantly increased risk (IRR = 1.13 [0.98–1.30]). For both classes of drugs, the risk for current users increased significantly with dose. For typical antipsychotics the IRRs increased from 1.31 (0.97–1.77) for low doses to 2.42 (1.91–3.06) for high doses (p<.001). For atypical agents the IRRs increased from 1.59 (1.03–2.46) for low doses to 2.86 (2.25–3.65) for high doses (p=.015). The IRR for atypical vs typical antipsychotics was 1.14 (.93–1.39). Similar findings were present in the propensity-score matched cohort. Conclusion Current users of both typical and atypical antipsychotics had a similar, dose-related increased risk of sudden cardiac death. PMID:19144938

Factors Influencing the Clinical Stratification of Suitability to Drive after Stroke: A Qualitative Study.

2015-01-01

While a clinical pre-selection screening process for a stroke patient's suitability for driving has been acknowledged, little is known about the factors or processes influencing this screening typically conducted by clinicians practicing at a generalist level. This study explored this clinical stratification process through the use of semi-structured interviews with senior occupational therapists (n = 17) and stroke physicians (n = 7) using qualitative description methodology. The findings revealed a trichotomy stratification of stroke patients for driving in the clinical setting; those who are fit to drive, unfit to drive, and a "maybe" group who need more detailed assessment and observation. Factors that had a major influence on this clinical-based stratification of driving suitability were client's levels of awareness, insight, and impulsivity. A period of prolonged contact with the client was preferential to guide the stratification decision in order for clinicians to build a comprehensive picture of the person. A mix of assessment approaches including standardized assessment but with increased emphasis on naturalistic observation of functional performance underpinned the clinical stratification process. This study uncovers some of the factors and processes influencing the early clinical-based stratification of driving suitability after stroke, and highlights the contribution of the generalist practitioner in the assessment of fitness to drive continuum.

Meta-Analysis of the Effects of Computerized Cognitive Training on Executive Functions: a Cross-Disciplinary Taxonomy for Classifying Outcome Cognitive Factors.

PubMed

Webb, Shannon L; Loh, Vanessa; Lampit, Amit; Bateman, Joel E; Birney, Damian P

2018-06-01

The growing prevalence of neurodegenerative disorders associated with aging and cognitive decline has generated increasing cross-disciplinary interest in non-pharmacological interventions, such as computerized cognitive training (CCT), which may prevent or slow cognitive decline. However, inconsistent findings across meta-analytic reviews in the field suggest a lack of cross-disciplinary consensus and on-going debate regarding the benefits of CCT. We posit that a contributing factor is the lack of a theoretically-based taxonomy of constructs and representative tasks typically used. An integration of the Cattell-Horn-Carroll (CHC) taxonomy of broad and narrow cognitive factors and the Miyake unity-diversity theory of executive functions (EF) is proposed (CHC-M) as an attempt to clarify this issue through representing and integrating the disciplines contributing to CCT research. The present study assessed the utility of this taxonomy by reanalyzing the Lampit et al. (2014) meta-analysis of CCT in healthy older adults using the CHC-M framework. Results suggest that: 1) substantively different statistical effects are observed when CHC-M is applied to the Lampit et al. meta-analytic review, leading to importantly different interpretations of the data; 2) typically-used classification practices conflate Executive Function (EF) tasks with fluid reasoning (Gf) and retrieval fluency (Gr), and Attention with sensory perception; and 3) there is theoretical and practical advantage in differentiating attention and working-memory tasks into the narrow shifting, inhibition, and updating EF domains. Implications for clinical practice, particularly for our understanding of EF are discussed.

Psychopathological changes and dysfunction in emotion processing have been described for anorexia nervosa (AN). Yet, findings are applicable to adult patients only. Furthermore, potential for discriminative power in clinical practice in relation to clinical parameters has to be discussed. The aim of this study was to investigate psychopathology and emotional face processing in adolescent female patients with AN. In a sample of 15 adolescent female patients with AN (16.2 years, SD ± 1.26) and 15 age and sex matched controls we assessed alexithymia, depression, anxiety and empathy in addition to emotion labelling and social information processing. AN patients had significantly higher alexithymia, higher levels of depression, and state and trait anxiety compared to controls. There was a trend for a lower ability to recognize disgust. Happiness as a positive emotion was recognized better. All facial expressions were recognized significantly faster by AN patients. Associations of pathological eating behaviour and trait anxiety were seen. In accordance with the stress reduction hypothesis, typical psychopathology of alexithymia, anxiety and depression is prevalent in female adolescent AN patients. It is present detached from physical stability. Pathogenesis of AN is multifactorial and already fully present in adolescence. An additional reinforcement process can be discussed. For clinical practice, those parameters might have a better potential for early prognostic factors related to AN than physical parameters and possible implication for intervention is given.

This paper describes a system that uses electronic forms to collect patient and procedure data for clinical trials. During clinical trials, patients are typically required to provide background information such as demographics and medical history, as well as review and complete any consent forms. Physicians or their assistants then usually have additional forms for recording technical data from the procedure and for gathering follow-up information from patients after completion of the procedure. This approach can lead to substantial amounts of paperwork to collect and manage over the course of a clinical trial with a large patient base. By using e-forms instead, data can be transmitted to a single, centralized database, reducing the problem of managing paper forms. Additionally, the system can provide a means for relaying information from the database to the physician on his/her portable wireless device, such as to alert the physician when a patient has completed the pre-procedure forms and is ready to begin the procedure. This feature could improve the workflow in busy clinical practices. In the future, the system could be expanded so physicians could use their portable wireless device to pull up entire hospital records and view other pre-procedure data and patient images.

CADASIL (cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy) is caused by mutations in the NOTCH3 gene, affecting the number of cysteines in the extracellular domain of the receptor, causing protein misfolding and receptor aggregation. The pathogenic role of cysteine-sparing NOTCH3 missense mutations in patients with typical clinical CADASIL syndrome is unknown. The aim of this article is to describe these mutations to clarify if any could be potentially pathogenic. Articles on cysteine-sparing NOTCH3 missense mutations in patients with clinical suspicion of CADASIL were reviewed. Mutations were considered potentially pathogenic if patients had: (a) typical clinical CADASIL syndrome; (b) diffuse white matter hyperintensities; (c) the 33 NOTCH3 exons analyzed; (d) mutations that were not polymorphisms; and (e) Granular osmiophilic material (GOM) deposits in the skin biopsy. Twenty-five different mutations were listed. Four fulfill the above criteria: p.R61W; p.R75P; p.D80G; and p.R213K. Patients carrying these mutations had typical clinical CADASIL syndrome and diffuse white matter hyperintensities, mostly without anterior temporal pole involvement. Cysteine-sparing NOTCH3 missense mutations are associated with typical clinical CADASIL syndrome and typical magnetic resonance imaging (MRI) findings, although with less involvement of the anterior temporal lobe. Hence, these mutations should be further studied to confirm their pathological role in CADASIL.

Independence: proposing an initial framework for occupational therapy.

PubMed

Collins, Bethan

2017-11-01

The concept of independence is common in occupational therapy theory and practice but has rarely been clearly defined or conceptualized within in occupational therapy literature and there seems to be no standard definition. This can result in ambiguity, which potentially jeopardizes client-centred practice. This paper proposes an occupational therapy independence framework (OTIF) that synthesizes the range of characterizations of independence in a practically useful and occupation-centred manner. A review of literature, clinical experience, doctoral research and conversations with occupational therapists and disabled people, in particular those involved in a disability activism group and people with physical disabilities, has led to the development of the OTIF. Independence and interdependence, as characterized in the OTIF, occur when an individual exerts choice over occupational performance and can engage in occupations in a manner acceptable to the individual. Interdependence results when occupations are performed with another person whereas independence involves solitary occupational performance. Dependence typically results from inability to choose occupations or a mismatch between performance capacity and environmental factors. The OTIF has the potential to clarify the conceptualization of independence within occupational therapy theory and practice. This initial proposal is presented to stimulate debate and discussion.

Objective To quantify the role of practice characteristics in patient-specific receipt of dental diagnostic radiographic services. Data Source/Study Setting Florida Dental Care Study (FDCS). Study Design The FDCS was a 48-month prospective observational cohort study of community-dwelling adults. Participants' dentists were asked to complete a questionnaire about their practice characteristics. Data Collection/Extraction Methods In-person interviews and clinical examinations were conducted at baseline, 24, and 48 months, with 6-monthly telephone interviews in between. A single multivariate (four radiographic service outcomes) multivariable (multiple explanatory covariates) logistic regression was used to model service receipts. Principal Findings These practice characteristics were significantly associated with patient-specific receipt of radiographic services: number of different practices attended during follow-up; dentist's rating of how busy the practice was; typical waiting time for a new patient examination; practice size; percentage of patients that the dentist reported as interested in details about the condition of their mouths; percentage of African American patients in the practice; percentage of patients in the practice who do not have dental insurance; and dentist's agreement with a statement regarding whether patients should be dismissed from the practice. Effects had differential magnitudes and directions of effect, depending upon radiograph type. Conclusions Practice characteristics were significantly associated with patient-specific receipt of services. These effects were independent of patient-specific disease level and patient-specific sociodemographic characteristics, suggesting that practitioners do influence receipt of these diagnostic services. These findings are consistent with the conclusion that practitioners act in response to a mix of patients' interests, economic self-interests, and their own treatment preferences. PMID:16987308

Evaluation of the Expression Profile of Extrapyramidal Symptoms Due to Antipsychotics by Data Mining of Japanese Adverse Drug Event Report (JADER) Database.

PubMed

2017-01-01

 Typical antipsychotics are easily expressed as adverse events such as extrapyramidal symptom (EPS). On the other hand, incidence of adverse events due to atypical antipsychotics is low. Therefore, currently, atypical antipsychotics are widely used to treat schizophrenia. However, it has been reported that there is no difference in the frequency of EPS in atypical and typical antipsychotics. This study aimed to evaluate the expression profile of EPS in atypical and typical antipsychotics treatment using the Japanese Adverse Drug Event Report (JADER) database. We analyzed reports of EPS in the JADER database and calculated the reporting odds ratio (ROR) of antipsychotics potentially associated with EPS. We applied the Weibull shape parameter to time-to-event data in the JADER database. Consequently, there was little information to distinguish between the ROR of atypical and typical antipsychotics. A significant difference related to the time of onset of EPS in both antipsychotics was not recognized. However, when comparing each drug, Paliperidone, Perospirone, Blonanserin, and Aripiprazole were relatively developed as EPS in the early stage. On the other hand, Risperidone, Clozapine, Olanzapine, and Quetiapine were developed as EPS not only at an early stage but also after long-term use. In addition, this finding was suggested from the result of the cumulative incidence of EPS in each drug and of the time-to-onset analysis using Weibull distribution. These findings may contribute to future clinical practice because we revealed the expression profile of EPS in treatment with atypical and typical antipsychotics.

Comparative effectiveness research (CER) strives for evidence to inform clinical decisions for specific clients in typical health care settings. While the randomized controlled trial (RCT) is well-aligned with the objectives of CER, this design may not be feasible or applicable to all research questions, particularly those pertaining to clinical decision making and individually based change. It is important, therefore, to consider alternative approaches, especially when studying complex and subjective outcomes such as children's participation. We propose the use of interrupted time series (ITS) quasi-experimental design for its potential application in determining the effectiveness of participation-focused interventions. In this perspective, ITS design is described, ascertaining its advantages and limitations, and suggestions are provided to overcome challenges to implementation. Results of a case study using the ITS approach to evaluate changes in participation of an adolescent with physical disabilities are described. Finally, strategies to implement this design in practice are suggested.

2015-01-01

Background: Physical therapy care for musculoskeletal conditions includes an ongoing process that systematically considers and prioritises diagnostic hypotheses. These diagnostic hypotheses include those that are typical for common musculoskeletal conditions, and must also include more rare conditions that would require care outside the scope of practice of the physical therapist. When additional screening is required, physical therapists collaborate with other providers or directly order the appropriate tests to rule out suspected pathology. Case Description: This article illustrates the use of musculoskeletal imaging ordered by a physical therapist to guide ongoing management of a patient with back pain and a history of cancer. Outcomes: The patient successfully returned to moderate-intensity sport activities after a course of physical therapy. Discussion: This case provides an example of how clinical diagnostic reasoning combined with clinical privileges to order musculoskeletal imaging can facilitate diagnostic accuracy in a timely and cost-efficient manner.

Antibody-drug conjugates (ADCs) typically consist of a cytotoxic drug covalently bound to an antibody by a linker. These conjugates have the potential to substantially improve efficacy and reduce toxicity compared with cytotoxic small-molecule drugs. Since ADCs are generally complex heterogeneous mixtures of multiple species, these novel therapeutic products present unique bioanalytical challenges. The growing number of ADCs being developed across the industry suggests the need for alignment of the bioanalytical methods or approaches used to assess the multiple species and facilitate consistent interpretation of the bioanalytical data. With limited clinical data, the current strategies that can be used to provide insight into the relationship between the multiple species and the observed clinical safety and efficacy are still evolving. Considerations of the bioanalytical strategies for ADCs based on the current industry practices that take into account the complexity and heterogeneity of ADCs are discussed.

Should extended blastocyst culture include Day 7?

PubMed

Hammond, Elizabeth R; Cree, Lynsey M; Morbeck, Dean E

2018-06-01

Extended culture to the blastocyst stage is widely practised, improving embryo selection and promoting single embryo transfer. Selection of useable blastocysts typically occurs on Days 5 and 6 of embryo culture. Embryos not suitable for transfer, biopsy or cryopreservation after Day 6 are routinely discarded. Some embryos develop at a slower rate, however, forming blastocysts on Day 7 of culture. Day 7 blastocysts can be viable, they can be of top morphological grade, euploid and result in a healthy live birth. Since ending culture on Day 6 is current practice in most clinics, viable Day 7 blastocysts may be prematurely discarded. Although Day 7 blastocysts make up only 5% of useable blastocysts, those which are suitable for cryopreservation or biopsy are clinically significant. Overall, culturing embryos an additional day increases the number of useable embryos per IVF cycle and provides further opportunity for pregnancy for patients, especially those who have only a few or low-quality blastocysts.

Burning mouth syndrome (BMS) refers to chronic orofacial pain, unaccompanied by mucosal lesions or other evident clinical signs. It is observed principally in middle-aged patients and postmenopausal women. BMS is characterized by an intense burning or stinging sensation, typically on the tongue or in other areas of the oral mucosa. It can be accompanied by other sensory disorders such as dry mouth or taste alterations. Probably of multifactorial origin, and often idiopathic, with a still unknown etiopathogenesis in which local, systemic and psychological factors are implicated. Currently there is no consensus on the diagnosis and classification of BMS. This study reviews the literature on this syndrome, with special reference to the etiological factors that may be involved and the clinical aspects they present. The diagnostic criteria that should be followed and the therapeutic management are discussed with reference to the most recent studies.

2016-04-09

Bipolar disorder is a recurrent chronic disorder characterised by fluctuations in mood state and energy. It affects more than 1% of the world's population irrespective of nationality, ethnic origin, or socioeconomic status. Bipolar disorder is one of the main causes of disability among young people, leading to cognitive and functional impairment and raised mortality, particularly death by suicide. A high prevalence of psychiatric and medical comorbidities is typical in affected individuals. Accurate diagnosis of bipolar disorder is difficult in clinical practice because onset is most commonly a depressive episode and looks similar to unipolar depression. Moreover, there are currently no valid biomarkers for the disorder. Therefore, the role of clinical assessment remains key. Detection of hypomanic periods and longitudinal assessment are crucial to differentiate bipolar disorder from other conditions. Current knowledge of the evolving pharmacological and psychological strategies in bipolar disorder is of utmost importance. Copyright © 2016 Elsevier Ltd. All rights reserved.

Objective To examine disease activity and clinical outcomes, and describe overall patterns of systemic lupus erythematosus (SLE) care in patients who received belimumab in a real-world clinical setting. Methods This observational cohort study was conducted in US clinical practices. Rheumatologists (n=92) identified adults with SLE who had received ≥8 infusions of belimumab plus standard of care (SoC). Physicians assessed disease outcomes at 6-month intervals using patient medical charts, for up to 24 months. The primary outcome was physician-assessed change in SLE disease. Other outcomes included change in steroid use, laboratory tests and healthcare resource utilisation (HCRU). Results Of 501 patients (intent-to-treat population (ITT)), 446 were female, mean age was 43.3 years and 98% had moderate/severe disease activity at baseline (first dose of belimumab). Data for 277 patients who completed 24 months of belimumab treatment were available. Among the ITT, a ≥50% improvement in overall clinical response between baseline and month 6 was reported for 48.7% of patients; continued improvement was seen at all subsequent 6-month intervals relative to the previous timepoint. The percentage of patients with moderate/severe disease also decreased at each timepoint. At baseline, 77.0% of patients received steroids at a mean (SD) prednisone equivalent dose of 19.9 (14.39) mg/day, which decreased to 8.4 (7.35) mg/day at month 6 and 6.1 (9.31) mg/day at month 24. Abnormal laboratory values typically associated with SLE also demonstrated improvements at month 6, which continued through 24 months. HCRU decreased over the duration of the study. Conclusions Patients with SLE who received belimumab plus SoC for up to 24 months demonstrated improvements in disease severity and laboratory values and a reduction in steroid use and HCRU as early as month 6. Improvements continued through 24 months, providing evidence of reduced disease activity among patients taking belimumab in real-world clinical practice. PMID:26835146

Acute vulvar pain in a lady with post circumcision inclusion cyst of the vulva containing stones: a case report.

2014-01-06

Despite global eradication efforts, female genital cutting is still deep routed practice in some parts of Asia and East Africa. The crude and unscientific natures of the practice lead to many complications. Epidermoid inclusion cysts of the vulva are one of the late complications of female genital cutting and typically present as painless cystic swellings. But clinical presentation as 'stone' containing, hard vulvar mass is reported only once in the literature and presentation with acute vulvar pain has never been documented. A 21 yrs old, Ethiopian, unmarried, lady presented with sever acute vulvar pain, discharge, and a stony hard vulvar swelling 13 years after type-III female genital cutting (infibulation). Surgical excision of the cyst, which contained two 'stones' inside it, and defibulation were done. Histopathology confirmed calcified, keratinizing epidermoid inclusion cyst of the vulva. Clinicians, in areas where female genital cutting is prevalent, should be aware of such unusual late vulvar complication of the practice which might be misdiagnosed for other solid vulvar swellings and be familiar with the appropriate management.

The aims of this study were to describe nurses' perceptions of nursing activities and analyze for consistency with top-of-license (TOL) practice. The Advisory Board Company expert panel proposed 8 TOL core nursing responsibilities representing practice at its potential. Thus far, no empirical work has examined nursing practices relative to TOL, from staff nurses' points of view. This qualitative study used focus groups to explore perceptions of typical nursing activities. We analyzed activities for themes that described nurses' work during typical shifts. Nurses' full scope of work included TOL-consistent categories, as well as categories that did not exemplify TOL practice, such as nonnursing care. A proposed model was developed, which depicts nurses' total scope of work, inclusive of all activity categories. In addition, hindrances to TOL practice were also identified. Findings from this study can inform leadership imperatives and the development of innovative, sustainable nursing practice models that support nursing practice at TOL.

Effective communication skills are essential to their ability to effectively contribute to their clinical team and the patient care they deliver. The authors propose an interactive workshop that can support students' deliberate practice of communication skills. The authors designed a simulation workshop that affords students the opportunity to practice their communication and peer-to-peer coaching skills. Using LEGOs, a one-hour workshop was conducted with medical students. Students were divided into groups of two. Each student took on a different role: teacher or builder. Teachers were tasked with instructing builders on how to construct a pre-made LEGO structure, not allowing builders to look at the structure. A group debriefing followed to evaluate the activity and explore the themes that emerged. Twenty first-year medical students and 25 fourth-year medical students participated in this activity. Most groups were successful in reproducing the pre-made structure. Groups that pre-briefed before building were most successful. Unsuccessful groups did not define orientation or direction in mutually understood terms, resulting in the creation of an incorrect mirror image of the structure - a common phenomenon seen during the teaching of procedures in the clinical learning environment. The workshop was well received. Students made requests to have similar sessions throughout their training to better support the development of effective communication skills. The workshop can easily be applied to other specialties to assist with procedural skills instruction or in workshops focusing on effective communication.

Data on absolute risks of outcomes and patterns of drug use in cost-effectiveness analyses are often based on randomised clinical trials (RCTs). The objective of this study was to evaluate the external validity of published cost-effectiveness studies by comparing the data used in these studies (typically based on RCTs) to observational data from actual clinical practice. Selective Cox-2 inhibitors (coxibs) were used as an example. The UK General Practice Research Database (GPRD) was used to estimate the exposure characteristics and individual probabilities of upper gastrointestinal (GI) events during current exposure to nonsteroidal anti-inflammatory drugs (NSAIDs) or coxibs. A basic cost-effectiveness model was developed evaluating two alternative strategies: prescription of a conventional NSAID or coxib. Outcomes included upper GI events as recorded in GPRD and hospitalisation for upper GI events recorded in the national registry of hospitalisations (Hospital Episode Statistics) linked to GPRD. Prescription costs were based on the prescribed number of tables as recorded in GPRD and the 2006 cost data from the British National Formulary. The study population included over 1 million patients prescribed conventional NSAIDs or coxibs. Only a minority of patients used the drugs long-term and daily (34.5% of conventional NSAIDs and 44.2% of coxibs), whereas coxib RCTs required daily use for at least 6-9 months. The mean cost of preventing one upper GI event as recorded in GPRD was US$104k (ranging from US$64k with long-term daily use to US$182k with intermittent use) and US$298k for hospitalizations. The mean costs (for GPRD events) over calendar time were US$58k during 1990-1993 and US$174k during 2002-2005. Using RCT data rather than GPRD data for event probabilities, the mean cost was US$16k with the VIGOR RCT and US$20k with the CLASS RCT. The published cost-effectiveness analyses of coxibs lacked external validity, did not represent patients in actual clinical practice, and should not have been used to inform prescribing policies. External validity should be an explicit requirement for cost-effectiveness analyses.

Background Clinical practice guidelines are important for guiding practice, but it is unclear if they are commensurate with the available evidence. Methods We examined guidelines produced by cancer and gynecological societies and organizations and evaluated their coverage of and stance towards chemotherapy for advanced stage disease among 4 gynecological malignancies (breast, ovarian, cervical, endometrial cancer) where the evidence for the use of chemotherapy is very different (substantial and conclusive for breast and ovarian cancer, limited and suggesting no major benefit for cervical and endometrial cancer). Eligible societies and organizations were identified through systematic internet searches (last update June 2009). Pertinent websites were scrutinized for presence of clinical practice guidelines, and relative guidelines were analyzed. Results Among 224 identified eligible societies and organizations, 69 (31%) provided any sort of guidelines, while recommendations for chemotherapy on advanced stage gynecological malignancies were available in 20 of them. Only 14 had developed their own guideline, and only 5 had developed guidelines for all 4 malignancies. Use of levels of evidence and grades of recommendations, and aspects of the production, implementation, and timeliness of the guidelines did not differ significantly across malignancies. Guidelines on breast and ovarian cancer utilized significantly more randomized trials and meta-analyses. Guidelines differed across malignancies on their coverage of disease-free survival (p = 0.033), response rates (p = 0.024), symptoms relief (p = 0.005), quality of life (p = 0.001) and toxicity (p = 0.039), with breast and ovarian cancer guidelines typically covering more frequently these outcomes. All guidelines explicitly or implicitly endorsed the use of chemotherapy. Conclusions Clinical practice guidelines are provided by the minority of professional societies and organizations. Available guidelines tend to recommend chemotherapy even for diseases where the effect of chemotherapy is controversial and recommendations are based on scant evidence. PMID:21611154

No formal guidelines for diagnosing psychogenic nonepileptic seizures (PNES) in children exist, and little is known about the clinical practice of diagnosing PNES in the pediatric setting. We therefore performed a national survey as a first step to document pediatricians' current diagnostic practice for PNES. A questionnaire was distributed to all pediatricians (n=64) working in the field of neuropediatrics and/or social pediatrics in the Danish hospital setting to uncover their use of terminology and of the International Classification of Diseases, 10th Revision (ICD-10) codes as well as their clinical diagnostic approach to pediatric PNES. The questionnaire included questions on 18 history and 24 paroxysmal event characteristics. The response rate was 95% (61/64). There was no consensus on which terminology and diagnostic codes to use. Five history characteristics (psychosocial stressors/trauma, sexual abuse, paroxysmal events typically occur in stressful situations, no effect of antiepileptic drugs, and physical abuse) and six paroxysmal event characteristics (resisted eyelid opening, avoidance/guarding behavior, paroxysmal events occur in the presence of others, closed eyes, rarely injury related to paroxysmal event, and absence of postictal change) were agreed to be very predictive of PNES by at least 50% of the pediatricians. Supplementary diagnostic tests such as blood chemistry measurements (e.g., blood glucose or acute phase reactants; i.e., white blood cell count and C-reactive protein) and electrocardiography were inconsistently used. Only 49% of the respondents reported to use video-electroencephalography (VEEG) frequently as part of their diagnostic procedure. To our knowledge, this is the first national survey that offers a systematic insight into the diagnostic practices for children with PNES in the hospital setting. The results demonstrate a need for clinical guidelines to improve and systematize the diagnostic approach for PNES in children. Wiley Periodicals, Inc. © 2014 International League Against Epilepsy.

Background and purpose A rapid learning approach has been proposed to extract and apply knowledge from routine care data rather than solely relying on clinical trial evidence. To validate this in practice we deployed a previously developed decision support system (DSS) in a typical, busy clinic for non-small cell lung cancer (NSCLC) patients. Material and methods Gender, age, performance status, lung function, lymph node status, tumor volume and survival were extracted without review from clinical data sources for lung cancer patients. With these data the DSS was tested to predict overall survival. Results 3919 lung cancer patients were identified with 159 eligible for inclusion, due to ineligible histology or stage, non-radical dose, missing tumor volume or survival. The DSS successfully identified a good prognosis group and a medium/poor prognosis group (2 year OS 69% vs. 27/30%, p < 0.001). Stage was less discriminatory (2 year OS 47% for stage I–II vs. 36% for stage IIIA–IIIB, p = 0.12) with most good prognosis patients having higher stage disease. The DSS predicted a large absolute overall survival benefit (~40%) for a radical dose compared to a non-radical dose in patients with a good prognosis, while no survival benefit of radical radiotherapy was predicted for patients with a poor prognosis. Conclusions A rapid learning environment is possible with the quality of clinical data sufficient to validate a DSS. It uses patient and tumor features to identify prognostic groups in whom therapy can be individualized based on predicted outcomes. Especially the survival benefit of a radical versus non-radical dose predicted by the DSS for various prognostic groups has clinical relevance, but needs to be prospectively validated. PMID:25241994

To assess the relationship between the addition of advanced monitoring variables and changes in clinical decision-making. A 15-questions survey was anonymously emailed to international experts and physician members of five anesthesia societies which focused on assessing treatment decisions of clinicians during three realistic clinical scenarios measured at two distinct time points. The first is when typical case information and basic monitoring (T1) were provided, and then once again after the addition of advanced monitoring variables (T2). We hypothesized that the addition of advanced variables would increase the incidence of an optimal therapeutic decision (a priori defined as the answer with the highest percentage of expert agreement) and decrease the variability among the physician's suggested treatments. The survey was completed by 18 experts and 839 physicians. Overall, adding advanced monitoring did not significantly increase physician response accuracy, with the least substantial changes noted on questions related to volume expansion or vasopressor administration. Moreover, advanced monitoring data did not significantly decrease the high level of initial practice variability in physician suggested treatments (P = 0.13), in contrast to the low variability observed within the expert group (P = 0.039). Additionally, 5-10 years of practice (P < 0.0001) and a cardiovascular subspecialty (P = 0.048) were both physician characteristics associated with a higher rate of optimal therapeutic decisions. The addition of advanced variables was of limited benefit for most physicians, further indicating the need for more in depth education on the clinical value and technical understanding of such variables.

Objective. The paper investigates the presence of autism using the functional brain connectivity measures derived from electro-encephalogram (EEG) of children during face perception tasks. Approach. Phase synchronized patterns from 128-channel EEG signals are obtained for typical children and children with autism spectrum disorder (ASD). The phase synchronized states or synchrostates temporally switch amongst themselves as an underlying process for the completion of a particular cognitive task. We used 12 subjects in each group (ASD and typical) for analyzing their EEG while processing fearful, happy and neutral faces. The minimal and maximally occurring synchrostates for each subject are chosen for extraction of brain connectivity features, which are used for classification between these two groups of subjects. Among different supervised learning techniques, we here explored the discriminant analysis and support vector machine both with polynomial kernels for the classification task. Main results. The leave one out cross-validation of the classification algorithm gives 94.7% accuracy as the best performance with corresponding sensitivity and specificity values as 85.7% and 100% respectively. Significance. The proposed method gives high classification accuracies and outperforms other contemporary research results. The effectiveness of the proposed method for classification of autistic and typical children suggests the possibility of using it on a larger population to validate it for clinical practice.

Decreased physical activity has been linked to poor fitness and obesity, resulting in increased risk for health concerns. The objective is to study the relationships between children's motor coordination and their physical activity, sedentary behaviour, fitness and weight status in a cross-cultural study in the United States and Israel. Participants included 118 children 6-11 years of age: 53 children with developmental coordination disorder (DCD) and 65 typical children. The US sample included 31 DCD children and 44 typical children. The Israeli sample included 22 DCD children and 21 typical children. Participants were assessed on Movement Assessment Battery for Children 2, strength test of the Bruininks-Oseretsky Test of Motor Proficiency 2 and Six-minute Walk Test and wore an accelerometer. Parents completed physical activity questionnaires and demographic information. Body mass index was calculated based on height and weight. Testing took place in two sessions. Findings are that in both Israel and the United States, children with DCD demonstrated significantly reduced physical activity, increased sedentary behaviour, poorer fitness and increased overweight compared with typical children. No significant differences were found for country. With relevance to clinical practice, fitness and obesity are major concerns for children with DCD in both countries. Inclusion of occupational therapy in health promotion for this population is critical. Additional studies with testers blind to group, larger samples and other countries are recommended.

Errorless Learning in Cognitive Rehabilitation: A Critical Review

PubMed Central

Middleton, Erica L.; Schwartz, Myrna F.

2012-01-01

Cognitive rehabilitation research is increasingly exploring errorless learning interventions, which prioritize the avoidance of errors during treatment. The errorless learning approach was originally developed for patients with severe anterograde amnesia, who were deemed to be at particular risk for error learning. Errorless learning has since been investigated in other memory-impaired populations (e.g., Alzheimer's disease) and acquired aphasia. In typical errorless training, target information is presented to the participant for study or immediate reproduction, a method that prevents participants from attempting to retrieve target information from long-term memory (i.e., retrieval practice). However, assuring error elimination by preventing difficult (and error-permitting) retrieval practice is a potential major drawback of the errorless approach. This review begins with discussion of research in the psychology of learning and memory that demonstrates the importance of difficult (and potentially errorful) retrieval practice for robust learning and prolonged performance gains. We then review treatment research comparing errorless and errorful methods in amnesia and aphasia, where only the latter provides (difficult) retrieval practice opportunities. In each clinical domain we find the advantage of the errorless approach is limited and may be offset by the therapeutic potential of retrieval practice. Gaps in current knowledge are identified that preclude strong conclusions regarding a preference for errorless treatments over methods that prioritize difficult retrieval practice. We offer recommendations for future research aimed at a strong test of errorless learning treatments, which involves direct comparison with methods where retrieval practice effects are maximized for long-term gains.

Several diagnostic criteria for multifocal motor neuropathy have been proposed in recent years and a beneficial effect of intravenous immunoglobulin (IVIg) and various other immunomodulatory drugs has been suggested in several trials and uncontrolled studies. The objectives were to prepare consensus guidelines on the definition, investigation and treatment of multifocal motor neuropathy. Disease experts and a patient representative considered references retrieved from MEDLINE and the Cochrane Library in July 2004 and prepared statements which were agreed in an iterative fashion. The Task Force agreed good practice points to define clinical and electrophysiological diagnostic criteria for multifocal motor neuropathy and investigations to be considered. The principal recommendations and good practice points were: (i) IVIg (2 g/kg given over 2-5 days) should be considered as the first line treatment (level A recommendation) when disability is sufficiently severe to warrant treatment. (ii) Corticosteroids are not recommended (good practice point). (iii) If initial treatment with IVIg is effective, repeated IVIg treatment should be considered (level C recommendation). The frequency of IVIg maintenance therapy should be guided by the individual response (good practice point). Typical treatment regimens are 1 g/kg every 2-4 weeks or 2 g/kg every 4-8 weeks (good practice point). (iv) If IVIg is not or not sufficiently effective then immunosuppressive treatment may be considered. Cyclophosphamide, ciclosporin, azathioprine, interferon beta1a, or rituximab are possible agents (good practice point). (v) Toxicity makes cyclophosphamide a less desirable option (good practice point).

The objective of this review was to identify current practices and relevant patient-reported and objective outcome measures with regard to rehabilitation protocols directed at the lumbar spine in perioperative procedure settings in order to inform clinical practice and future research. A literature search was performed in MEDLINE, CINAHL (Cumulative Index to Nursing and Allied Health Literature), the Cochrane Central Register of Controlled Trials, PEDro (Physiotherapy Evidence Database), and PubMed using terms relevant to surgical interventions, rehabilitation, and the lumbar spine. Twenty-nine studies met the inclusion criteria, and 28 investigated postoperative forms of rehabilitation. Patient-reported outcomes typically used were pain and disability, although a wide range of objective measures based on physical capacities were often reported. Rehabilitation programs, for the most part, included some form of strengthening exercises alone or in combination with stabilization exercises, aerobic conditioning, stretching, or education. Despite most studies reporting statistically significant results between intervention groups, considering clinically significant improvement within intervention groups yielded a different portrait. A wide range of objective and subjective outcomes is used to document changes after active rehabilitation. Program components include both active and assisted interventions combined with various means of education and discussion. Multimodal rehabilitation protocols after lumbar surgery may be used to improve patient-reported and objective outcome measures such as pain, disability, and physical function. Further research should be conducted on the effects of preoperative rehabilitation programs. Copyright © 2016. Published by Elsevier Inc.

Scabies has been on the rise in France in recent years and has posed therapeutic problems, mainly due to the withdrawal of benzyl benzoate. The objective of this study was to describe prescribing practices for scabies in children. A national survey was conducted by means of a standardized questionnaire covering various clinical situations of scabies and the drugs used preferentially according to age, which was sent out between December 2014 and March 2015 to members of the clinical research group of the French Society of Paediatric Dermatology. Of the 38 experts contacted, 20 replied. For a typical case of scabies, 55% of the experts initially prescribed oral ivermectin for children aged 6 years, 15% prescribed ivermectin in children aged 2 years, and 5% in infants aged 3 months. Ivermectin was more widely prescribed after failure of prior treatment or recurrence of scabies, on skin lesions or impetigo, if precarious, especially for profuse hyperkeratotic scabies. A total of 35% of the experts reported no prescribing restrictions with regard to patient age or weight. Discrepancies were observed concerning the mode of administration and the time between consecutive doses. Esdepallethrin remained the preferred local treatment among the experts (38% of all topical prescriptions) except in asthmatic children, while permethrin was the least-prescribed topical agent. This study confirms the heterogeneity of our practices. Formal expert recommendations are awaited, particularly concerning the use of ivermectin in infants. Copyright © 2017.

Background There is much interest in virtual consultations using video technology. Randomized controlled trials have shown video consultations to be acceptable, safe, and effective in selected conditions and circumstances. However, this model has rarely been mainstreamed and sustained in real-world settings. Objective The study sought to (1) define good practice and inform implementation of video outpatient consultations and (2) generate transferable knowledge about challenges to scaling up and routinizing this service model. Methods A multilevel, mixed-method study of Skype video consultations (micro level) was embedded in an organizational case study (meso level), taking account of national context and wider influences (macro level). The study followed the introduction of video outpatient consultations in three clinical services (diabetes, diabetes antenatal, and cancer surgery) in a National Health Service trust (covering three hospitals) in London, United Kingdom. Data sources included 36 national-level stakeholders (exploratory and semistructured interviews), longitudinal organizational ethnography (300 hours of observations; 24 staff interviews), 30 videotaped remote consultations, 17 audiotaped face-to-face consultations, and national and local documents. Qualitative data, analyzed using sociotechnical change theories, addressed staff and patient experience and organizational and system drivers. Quantitative data, analyzed via descriptive statistics, included uptake of video consultations by staff and patients and microcategorization of different kinds of talk (using the Roter interaction analysis system). Results When clinical, technical, and practical preconditions were met, video consultations appeared safe and were popular with some patients and staff. Compared with face-to-face consultations for similar conditions, video consultations were very slightly shorter, patients did slightly more talking, and both parties sometimes needed to make explicit things that typically remained implicit in a traditional encounter. Video consultations appeared to work better when the clinician and patient already knew and trusted each other. Some clinicians used Skype adaptively to respond to patient requests for ad hoc encounters in a way that appeared to strengthen supported self-management. The reality of establishing video outpatient services in a busy and financially stretched acute hospital setting proved more complex and time-consuming than originally anticipated. By the end of this study, between 2% and 22% of consultations were being undertaken remotely by participating clinicians. In the remainder, clinicians chose not to participate, or video consultations were considered impractical, technically unachievable, or clinically inadvisable. Technical challenges were typically minor but potentially prohibitive. Conclusions Video outpatient consultations appear safe, effective, and convenient for patients in situations where participating clinicians judge them clinically appropriate, but such situations are a fraction of the overall clinic workload. As with other technological innovations, some clinicians will adopt readily, whereas others will need incentives and support. There are complex challenges to embedding video consultation services within routine practice in organizations that are hesitant to change, especially in times of austerity. PMID:29625956

Costello syndrome is a rare genetic disorder with an estimated 300 medical cases worldwide. Typical features that characterize this syndrome include short stature, macrocephaly, developmental delay, loose skin folds, distinctive coarse facial features, and multiorgan system anomalies. The following case report discusses the anesthetic management for a 3-year-old boy undergoing general anesthesia for a scheduled dental restoration, hydrocelectomy, inguinal hernia repair, and bilateral myringotomy with placement of pressure equalization tubes. A scarcity of literature for the anesthetic management of Costello syndrome (also known as faciocutaneoskeletal syndrome) exists. Utilizing an overview of the pertinent literature, clinical practice recommendations are suggested for the anesthetic implications of managing a pediatric patient with this rare syndrome.

It focuses on the overall concept and practical realisation of the cornerstone within this transition, the Macintosh Mosaic Software Architecture (MMSA) which delivers now more than 90% of the clinical data which is entered on the wards and within the operating rooms. Besides the technical problems of the project, the paper also describes some aspects of the organisational challenges which took place within a typical German University Hospital during the last 4 Years and which mainly affect the daily management of a large HIS.

Developmental improvements in dynamic control of fingertip forces last throughout childhood and into adolescence

2013-01-01

While it is clear that the development of dexterous manipulation in children exhibits dramatic improvements over an extended period, it is difficult to separate musculoskeletal from neural contributors to these important functional gains. This is in part due to the inability of current methods to disambiguate improvements in hand strength from gains in finger dexterity (i.e., the dynamic control of fingertip force vectors at low magnitudes). We adapted our novel instrumentation to evaluate finger dexterity in 130 typically developing children between the ages of 4 and 16 yr. We find that finger dexterity continues to develop well into late adolescence and musculoskeletal growth and strength are poorly correlated with the improvements in dexterity. Importantly, because these behavioral results seem to mirror the known timelines of neuroanatomical development up to adolescence, we speculate that they reflect the functional benefits of such continual neural maturation. This novel perspective now enables the systematic study of the functional roles of specific neuroanatomical structures and their connectivity, maturity, and plasticity. Moreover, the temporal dynamics of the fingertip force vectors shows improvements in stability that provide a novel way to look at the maturation of finger control. From a clinical perspective, our results provide a practical means to chart functional development of dexterous manipulation in typically developing children and could be adapted for clinical use and for use in children with developmental disorders.

Formal testing of 3 year old children is a new feature in the revised version of the Movement Assessment Battery for Children (Movement ABC-2). Our study evaluated the reliability and explored the clinical applicability of the Movement ABC-2 Test in this young age group. A total of 50 typically children were given two trials of the test within a one to two week interval by two physical therapists: same assessor (n=28 children) and different assessors (n=22 children). Psychometric properties were evaluated by calculating internal consistency (Cronbach α), intra-class correlation (ICC), the standard error of measurement (SEM), the smallest detectable difference (SDD) and Kappa values for classification agreement. The results are promising for future implementation of the Movement ABC-2 in clinical practice. The children's performance was highly reproducible when tested by the same assessor (ICC .94) The SEM was 1.7 or 2.1 standard scores for 90% or 95% confidence intervals respectively, making the test sensitive enough to detect individual changes. If two different assessors tested the children the ICC was .76. In conclusion, the revised test can be applied to assess motor performance in typically developing 3-year old children. Future studies are needed to confirm if the same can be said for children with motor delays. Copyright © 2011 Elsevier Ltd. All rights reserved.

Unfolding linac photon spectra and incident electron energies from experimental transmission data, with direct independent validation

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

2012-11-15

Purpose: In a recent computational study, an improved physics-based approach was proposed for unfolding linac photon spectra and incident electron energies from transmission data. In this approach, energy differentiation is improved by simultaneously using transmission data for multiple attenuators and detectors, and the unfolding robustness is improved by using a four-parameter functional form to describe the photon spectrum. The purpose of the current study is to validate this approach experimentally, and to demonstrate its application on a typical clinical linac. Methods: The validation makes use of the recent transmission measurements performed on the Vickers research linac of National Research Councilmore » Canada. For this linac, the photon spectra were previously measured using a NaI detector, and the incident electron parameters are independently known. The transmission data are for eight beams in the range 10-30 MV using thick Be, Al and Pb bremsstrahlung targets. To demonstrate the approach on a typical clinical linac, new measurements are performed on an Elekta Precise linac for 6, 10 and 25 MV beams. The different experimental setups are modeled using EGSnrc, with the newly added photonuclear attenuation included. Results: For the validation on the research linac, the 95% confidence bounds of the unfolded spectra fall within the noise of the NaI data. The unfolded spectra agree with the EGSnrc spectra (calculated using independently known electron parameters) with RMS energy fluence deviations of 4.5%. The accuracy of unfolding the incident electron energy is shown to be {approx}3%. A transmission cutoff of only 10% is suitable for accurate unfolding, provided that the other components of the proposed approach are implemented. For the demonstration on a clinical linac, the unfolded incident electron energies and their 68% confidence bounds for the 6, 10 and 25 MV beams are 6.1 {+-} 0.1, 9.3 {+-} 0.1, and 19.3 {+-} 0.2 MeV, respectively. The unfolded spectra for the clinical linac agree with the EGSnrc spectra (calculated using the unfolded electron energies) with RMS energy fluence deviations of 3.7%. The corresponding measured and EGSnrc-calculated transmission data agree within 1.5%, where the typical transmission measurement uncertainty on the clinical linac is 0.4% (not including the uncertainties on the incident electron parameters). Conclusions: The approach proposed in an earlier study for unfolding photon spectra and incident electron energies from transmission data is accurate and practical for clinical use.« less

Research suggests that stress and depressed mood are associated with food-related parenting practices (ie, parent feeding practices, types of food served at meals). However, current measures of parental stress, depressed mood, and food-related parenting practices are typically survey-based and assessed as static/unchanging characteristics, failing to account for fluctuations across time and context. Identifying momentary factors that influence parent food-related parenting practices will facilitate the development of effective interventions aimed at promoting healthy food-related parenting practices. In this study, we used ecological momentary assessment to examine the association between momentary factors (eg, stress, depressed mood) occurring early in the day and food-related parenting practices at the evening meal. Children aged 5 to 7 years and their families ( N = 150) from 6 racial and/or ethnic groups ( n = 25 each African American, Hispanic/Latino, Hmong, American Indian, Somali, and white families) were recruited for this mixed-methods study through primary care clinics. Higher stress and depressed mood earlier in the day predicted pressure-to-eat feeding practices and fewer homemade foods served at meals the same night. Effect modification was found for certain racial and/or ethnic groups with regard to engaging in pressure-to-eat feeding practices (ie, America Indian, Somali) or serving fewer homemade meals (ie, African American, Hispanic/Latino) in the face of high stress or depressed mood. Clinicians may want to consider discussing with parents the influence stress and depressed mood can have on everyday food-related parenting practices. Additionally, future researchers should consider using real-time interventions to reduce parental stress and depressed mood to promote healthy parent food-related parenting practices.

The field of autoimmune encephalitides associated with antibodies targeting cell-surface antigens is rapidly expanding and new antibodies are discovered frequently. Typical clinical presentations include cognitive deficits, psychiatric symptoms, movement disorders and seizures and the majority of patients respond well to immunotherapy. Pathophysiological mechanisms and clinical features are increasingly recognized and indicate hippocampal dysfunction in most of these syndromes. Here, we review the neuroimaging characteristics of autoimmune encephalitides, including N-methyl-d-aspartate (NMDA) receptor, leucine-rich glioma inactivated 1 (LGI1), contactin-associated protein-like 2 (CASPR2) encephalitis as well as more recently discovered and less frequent forms such as dipeptidyl-peptidase-like protein 6 (DPPX) or glycine receptor encephalitis. We summarize findings of routine magnetic resonance imaging (MRI) investigations as well as (18)F-fluoro-2-deoxy-d-glucose (FDG)-positron emission tomography (PET) and single photon emission tomography (SPECT) imaging and relate these observations to clinical features and disease outcome. We furthermore review results of advanced imaging analyses such as diffusion tensor imaging, volumetric analyses and resting-state functional MRI. Finally, we discuss contributions of these neuroimaging observations to the understanding of the pathophysiology of autoimmune encephalitides. Copyright © 2015 IBRO. Published by Elsevier Ltd.

The introduction of next generation sequencing (NGS) has revolutionized molecular diagnostics, though several challenges remain limiting the widespread adoption of NGS testing into clinical practice. One such difficulty includes the development of a robust bioinformatics pipeline that can handle the volume of data generated by high-throughput sequencing in a cost-effective manner. Analysis of sequencing data typically requires a substantial level of computing power that is often cost-prohibitive to most clinical diagnostics laboratories. To address this challenge, our institution has developed a Galaxy-based data analysis pipeline which relies on a web-based, cloud-computing infrastructure to process NGS data and identify genetic variants. It provides additional flexibility, needed to control storage costs, resulting in a pipeline that is cost-effective on a per-sample basis. It does not require the usage of EBS disk to run a sample. We demonstrate the validation and feasibility of implementing this bioinformatics pipeline in a molecular diagnostics laboratory. Four samples were analyzed in duplicate pairs and showed 100% concordance in mutations identified. This pipeline is currently being used in the clinic and all identified pathogenic variants confirmed using Sanger sequencing further validating the software.

Patterns of functional vision loss in glaucoma determined with archetypal analysis

Glaucoma is an optic neuropathy accompanied by vision loss which can be mapped by visual field (VF) testing revealing characteristic patterns related to the retinal nerve fibre layer anatomy. While detailed knowledge about these patterns is important to understand the anatomic and genetic aspects of glaucoma, current classification schemes are typically predominantly derived qualitatively. Here, we classify glaucomatous vision loss quantitatively by statistically learning prototypical patterns on the convex hull of the data space. In contrast to component-based approaches, this method emphasizes distinct aspects of the data and provides patterns that are easier to interpret for clinicians. Based on 13 231 reliable Humphrey VFs from a large clinical glaucoma practice, we identify an optimal solution with 17 glaucomatous vision loss prototypes which fit well with previously described qualitative patterns from a large clinical study. We illustrate relations of our patterns to retinal structure by a previously developed mathematical model. In contrast to the qualitative clinical approaches, our results can serve as a framework to quantify the various subtypes of glaucomatous visual field loss. PMID:25505132

Bipolar disorders are chronic and recurrent disorders that affect >1% of the global population. Bipolar disorders are leading causes of disability in young people as they can lead to cognitive and functional impairment and increased mortality, particularly from suicide and cardiovascular disease. Psychiatric and nonpsychiatric medical comorbidities are common in patients and might also contribute to increased mortality. Bipolar disorders are some of the most heritable psychiatric disorders, although a model with gene-environment interactions is believed to best explain the aetiology. Early and accurate diagnosis is difficult in clinical practice as the onset of bipolar disorder is commonly characterized by nonspecific symptoms, mood lability or a depressive episode, which can be similar in presentation to unipolar depression. Moreover, patients and their families do not always understand the significance of their symptoms, especially with hypomanic or manic symptoms. As specific biomarkers for bipolar disorders are not yet available, careful clinical assessment remains the cornerstone of diagnosis. The detection of hypomanic symptoms and longtudinal clinical assessment are crucial to differentiate a bipolar disorder from other conditions. Optimal early treatment of patients with evidence-based medication (typically mood stabilizers and antipsychotics) and psychosocial strategies is necessary.

Ambulatory Blood Pressure Monitoring in Clinical Practice: A Review

PubMed Central

Viera, Anthony J.; Shimbo, Daichi

2016-01-01

Ambulatory blood pressure monitoring offers the ability to collect blood pressure readings several times an hour across a 24-hour period. Ambulatory blood pressure monitoring facilitates the identification of white-coat hypertension, the phenomenon whereby certain individuals who are not on antihypertensive medication show elevated blood pressure in a clinical setting but show non-elevated blood pressure averages when assessed by ambulatory blood pressure monitoring. Additionally, readings can be segmented into time windows of particular interest, e.g., mean daytime and nighttime values. During sleep, blood pressure typically decreases, or dips, such that mean sleep blood pressure is lower than mean awake blood pressure. A non-dipping pattern and nocturnal hypertension are strongly associated with increased cardiovascular morbidity and mortality. Approximately 70% of individuals dip ≥10% at night, while 30% have non-dipping patterns, when blood pressure remains similar to daytime average, or occasionally rises above daytime average. The various blood pressure categorizations afforded by ambulatory blood pressure monitoring are valuable for clinical management of high blood pressure since they increase accuracy for diagnosis and the prediction of cardiovascular risk.

Although individuals with medical problems (e.g., diabetes, hypertension) can monitor their symptoms using objective measures (e.g., blood glucose, blood pressure), objective measures are not typically used by individuals with psychotic disorders to monitor symptoms of mental illness. To examine the benefits and limitations of the use of video self-observation for treatment of individuals with psychotic disorders. The authors reviewed studies examining video self-observation among individuals with severe mental illnesses. Individuals with psychotic disorders who viewed videos of themselves while symptomatic reported some benefit to this approach, with 1 study showing sustained improvement in understanding of mental illness. Still, some individuals reported negative feelings about the process, and also attributed symptoms to stress or drug abuse rather than their psychotic disorder. The authors found no studies examining the potential for video self-observation as a strategy to improve clinical decision-making in the context of mental health care. Implications of this approach for mental health recovery and clinical practice are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

The clinical trajectory of emerging bipolar disorder among the high-risk offspring of bipolar parents: current understanding and future considerations.

Duffy, A; Vandeleur, C; Heffer, N; Preisig, M

2017-11-22

Relatively little is known about the onset of bipolar disorder, yet the early illness course is already associated with significant morbidity and mortality. Therefore, characterizing the bipolar illness trajectory is key to risk prediction and early intervention advancement. In this narrative review, we discuss key findings from prospective longitudinal studies of the high-risk offspring of bipolar parents and related meta-analyses that inform us about the clinical trajectory of emerging bipolar disorder. Challenges such as phenotypic and etiologic heterogeneity and the non-specificity of early symptoms and syndromes are highlighted. Implications of the findings for both research and clinical practice are discussed. Bipolar disorder in young people at familial risk does not typically onset with a hypomanic or manic episode. Rather the first activated episode is often preceded by years of impairing psychopathological states that vary over development and across emerging bipolar subtype. Taking heterogeneity into account and adopting a more comprehensive approach to diagnosis seems necessary to advance earlier identification and our understanding of the onset of bipolar disorder.

Intensive care unit research ethics and trials on unconscious patients.

PubMed

Gillett, G R

2015-05-01

There are widely acknowledged ethical issues in enrolling unconscious patients in research trials, particularly in intensive care unit (ICU) settings. An analysis of those issues shows that, by and large, patients are better served in units where research is actively taking place for several reasons: i) they do not fall prey to therapeutic prejudices without clear evidential support, ii) they get a chance of accessing new and potentially beneficial treatments, iii) a climate of careful monitoring of patients and their clinical progress is necessary for good clinical research and affects the care of all patients and iv) even those not in the treatment arm of a trial of a new intervention must receive best current standard care (according to international evidence-based treatment guidelines). Given that we have discovered a number of 'best practice' regimens of care that do not optimise outcomes in ICU settings, it is of great benefit to all patients (including those participating in research) that we are constantly updating and evaluating what we do. Therefore, the practice of ICU-based clinical research on patients, many of whom cannot give prospective informed consent, ticks all the ethical boxes and ought to be encouraged in our health system. It is very important that the evaluation of protocols for ICU research should not overlook obvious (albeit probabilistic) benefits to patients and the acceptability of responsible clinicians entering patients into well-designed trials, even though the ICU setting does not and cannot conform to typical informed consent procedures and requirements.

Percutaneous coronary intervention versus coronary artery bypass grafting: where are we after NOBLE and EXCEL?

PubMed

Fortier, Jacqueline H; Shaw, Richard E; Glineur, David; Grau, Juan B

2017-11-01

The publication of the NOBLE and EXCEL trials, with seemingly conflicting results, brought into question whether percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) is better for low-risk patients with left main coronary artery stenosis (LMCAS). This review appraises the methods and results of NOBLE and EXCEL, contextualizes them within the literature, and determines how they may affect clinical practice. We appraised the trials and describe differences in methodology and results. NOBLE recruited primarily isolated LMCAS, and found that CABG was superior to PCI. EXCEL's population included patients LMCAS in the context of multivessel CAD, and found PCI and CABG were comparable. Both trials enrolled young patients with few comorbidities, and there was more protocol-mandated consistency in the procedural techniques and medical therapy of patients receiving PCI. The generalizability of these trials is limited by the use of young, healthy patients at highly skilled centres that rarely reflect typical clinical practice. If these studies are to maintain relevance, trialists must address the lack of protocolization of surgical interventions and inconsistent medical therapies. Unfortunately, the limitations of NOBLE and EXCEL mean that we are no closer to answering the question of what is the optimal treatment for patients with LMCAS.

Despite the early recognition of the potential of proton imaging to assist proton therapy (Cormack 1963 J. Appl. Phys. 34 2722), the modality is still removed from clinical practice, with various approaches in development. For proton-counting radiography applications such as computed tomography (CT), the water-equivalent-path-length that each proton has travelled through an imaged object must be inferred. Typically, scintillator-based technology has been used in various energy/range telescope designs. Here we propose a very different alternative of using radiation-hard CMOS active pixel sensor technology. The ability of such a sensor to resolve the passage of individual protons in a therapy beam has not been previously shown. Here, such capability is demonstrated using a 36 MeV cyclotron beam (University of Birmingham Cyclotron, Birmingham, UK) and a 200 MeV clinical radiotherapy beam (iThemba LABS, Cape Town, SA). The feasibility of tracking individual protons through multiple CMOS layers is also demonstrated using a two-layer stack of sensors. The chief advantages of this solution are the spatial discrimination of events intrinsic to pixelated sensors, combined with the potential provision of information on both the range and residual energy of a proton. The challenges in developing a practical system are discussed.

Endovascular Management of Refractory Hepatic Encephalopathy Complication of Transjugular Intrahepatic Portosystemic Shunt (TIPS): Comprehensive Review and Clinical Practice Algorithm

Transjugular intrahepatic portosystemic shunt (TIPS) has evolved as an effective intervention for treatment of complications of portal hypertension. The use of polytetrafluoroethylene-covered stents have improved the patency of the shunts and diminished the incidence of TIPS dysfunction. However, TIPS-related refractory hepatic encephalopathy (rHE) poses a significant challenge. Approximately 3–7 % of patients with TIPS develop rHE. Refractory hepatic encephalopathy is defined as a recurrent or persistent encephalopathy despite appropriate medical treatment. Hepatic encephalopathy can be an extremely debilitating complication that profoundly affects quality of life. The approach to management of patients with rHE is complex and typically requires collaboration between differentmore » specialties. Liver transplantation is the ultimate treatment for rHE; however, the ongoing shortage of organ donation markedly limits this treatment option. Alternative therapies such as shunt occlusion or reduction can control symptoms and serve as a ‘bridge’ therapy to liver transplantation. Therefore, interventional radiologists play a key role in the management of these patients by offering a variety of endovascular techniques. The purpose of this review is to highlight some of these endovascular techniques and to develop a therapeutic algorithm that can be applied in clinical practice for the management of rHE.« less

Despite the early recognition of the potential of proton imaging to assist proton therapy the modality is still removed from clinical practice, with various approaches in development.

Owing to a reported learning effect in patients with chronic cardiopulmonary disease, performance of at least two six-minute walk tests (6MWT) are recommended as standard practice. Patients with chronic heart failure (CHF) are typically elderly and frail and it is unknown whether current guidelines are practical in a clinical setting. The aim of this study was to determine whether repeat performance of 6MWTs in patients with CHF is related to between-test interval or baseline performance. This was a multisite observational study enrolling participants entering into heart failure rehabilitation programmes. Participants performed two 6MWTs with randomly allocated inter-test intervals between 15 and 90 minutes. Distance walked in the second test was compared with the first test using a paired t test. Eighty-eight participants (45 females, age 65 ± 14 years) with stable CHF were enrolled. Mean distance walked increased from 301 metres in test 1 to 313 metres in test 2 (p < 0.001). No significant change was recorded between test 1 and test 2 for those whose baseline distance was <300 metres. The interval between tests had no significant effect on the distance walked. The change in 6MWT distance was significantly associated with better baseline performance but not with the interval between tests.

Health promotion activities may decrease preventable diseases and health system overuse. This study examined how low-income Euro-American mothers described their health/wellness, self-care practices (SCP), and SCP benefits, barriers, and interpersonal influences (norms, modeling, and social support) affecting their SCP. This descriptive qualitative study used a convenience sample of 10 low-income, English-speaking mothers, 25-43 years old, seeking women's/children's health services at a large urban Texas health clinic. Data were collected via face-to-face interviews, using a standardized semistructured interview guide; data were analyzed using Miles and Huberman's qualitative research methods. All participants primarily described themselves positively and as mothers and workers. Most viewed health and wellness as distinct but typically included physical and emotional well-being. Mothers valued health and SCP for personal and family reasons. All identified SCP benefits. Most identified SCP barriers. Women viewed themselves as vital to family function and well-being, learned SCP primarily from parents during childhood, and described limited support for SCP. The results provide a better understanding of participants' self-care decision making and are useful in designing appropriate clinical health promotions. Reducing health inequities in low-income women requires further study of the underlying causes and development of effective policies and measures to address them. © 2011 Wiley Periodicals, Inc.

Gesture Therapy: A Vision-Based System for Arm Rehabilitation after Stroke

NASA Astrophysics Data System (ADS)

Sucar, L. Enrique; Azcárate, Gildardo; Leder, Ron S.; Reinkensmeyer, David; Hernández, Jorge; Sanchez, Israel; Saucedo, Pedro

Each year millions of people in the world survive a stroke, in the U.S. alone the figure is over 600,000 people per year. Movement impairments after stroke are typically treated with intensive, hands-on physical and occupational therapy for several weeks after the initial injury. However, due to economic pressures, stroke patients are receiving less therapy and going home sooner, so the potential benefit of the therapy is not completely realized. Thus, it is important to develop rehabilitation technology that allows individuals who had suffered a stroke to practice intensive movement training without the expense of an always-present therapist. Current solutions are too expensive, as they require a robotic system for rehabilitation. We have developed a low-cost, computer vision system that allows individuals with stroke to practice arm movement exercises at home or at the clinic, with periodic interactions with a therapist. The system integrates a web based virtual environment for facilitating repetitive movement training, with state-of-the art computer vision algorithms that track the hand of a patient and obtain its 3-D coordinates, using two inexpensive cameras and a conventional personal computer. An initial prototype of the system has been evaluated in a pilot clinical study with promising results.

Determine the socio-demographic and educational characteristics of and develop a profile of practice for Pediatric Dentists (PDs) in Puerto Rico. A 34-item questionnaire assessing 3 dimensions: socio-demographic and education, practice profile, and level of satisfaction/desire to relocate, was developed and pre-tested for comprehensiveness, validity, and reliability. Data were collected through telephone interviews by a calibrated interviewer, entered and tabulated using Excel (Microsoft Office 2010) and exported to SPSS v. 17 (SPSS Inc., Chicago, IL). Descriptive statistical analyses were conducted. Eighty percent (80%) of all of the licensed PDs in PR participated in our study. The typical PD in PR has been in practice for 19 years, is 48 years old, and spends 31 hours/week providing clinical care. Female PDs, who comprise 70% of the PD workforce, devote more time to clinical and managerial activities than do their male counterparts. Seventy-three percent (73%) of the current PD workforce will be retiring within the next 20 years and 70% are solo-practitioners. Most PDs (65%) participate in the government-subsidized dental insurance program "Mi Salud," which represents as much as 48% of their income. PDs beginning or ending their careers were more likely to be participating providers for "Mi Salud" than were those in mid-career. In evaluating the adequacy of the pediatric dentistry workforce in Puerto Rico, the socio-demographic information of the PDs and the characteristics of their practices must be taken into account. These variables must be examined in relation to epidemiological indicators as well as environmental factors, including the comprehensiveness of dental benefits and the adequacy of reimbursement levels by third-party payers, which when inadequate may lead to decreased access to care.

Last year saw the 20th anniversary edition of JECP, and in the introduction to the philosophy section of that landmark edition, we posed the question: apart from ethics, what is the role of philosophy 'at the bedside'? The purpose of this question was not to downplay the significance of ethics to clinical practice. Rather, we raised it as part of a broader argument to the effect that ethical questions - about what we should do in any given situation - are embedded within whole understandings of the situation, inseparable from our beliefs about what is the case (metaphysics), what it is that we feel we can claim to know (epistemology), as well as the meaning we ascribe to different aspects of the situation or to our perception of it. Philosophy concerns fundamental questions: it is a discipline requiring us to examine the underlying assumptions we bring with us to our thinking about practical problems. Traditional academic philosophers divide their discipline into distinct areas that typically include logic: questions about meaning, truth and validity; ontology: questions about the nature of reality, what exists; epistemology: concerning knowledge; and ethics: how we should live and practice, the nature of value. Any credible attempt to analyse clinical reasoning will require us to think carefully about these types of question and the relationships between them, as they influence our thinking about specific situations and problems. So, the answers to the question we posed, about the role of philosophy at the bedside, are numerous and diverse, and that diversity is illustrated in the contributions to this thematic edition. © 2015 John Wiley & Sons, Ltd.

An inquiry into chiropractors' intention to treat adolescent idiopathic scoliosis: a telephone survey.

Feise, R J

2001-01-01

The primary aim of this study was to (1) determine the clinical management approach of practicing chiropractors with regard to patients with adolescent idiopathic scoliosis and (2) measure the response rate of a telephone survey. A survey instrument was developed and pretested, and a case-specific clinical vignette was generated for a hypothetical typical 12-year-old girl with adolescent idiopathic scoliosis. The instrument addressed 3 domains: the specific management of idiopathic scoliosis, elements guiding the general selection of treatment recommendations, and demographics of respondents. The sample frame consisted of 62,000 US chiropractors, of whom 165 were randomly selected for the survey sample. Interviews were conducted by telephone through use of the tested survey instrument. The response rate was 69% (114/165). Of the 51 nonrespondents, 15 did not have a listed business telephone number and 24 were not in active practice. The response rate of those who met the inclusion criteria (practicing chiropractor with a listed telephone number) was 90% (114/126). The gender, chiropractic college, and years in practice of respondents in this survey were similar to those of respondents in 3 other national surveys. In general, the respondents would provide 6 months of "intensive" chiropractic therapy, then follow the patient for 4 years (near skeletal maturity). Eighty-two percent of respondents named diversified technique as their primary adjustive treatment, 87% would use exercise, and 30% would use electric muscle stimulation as an adjunct to manual therapy. Most surveyed chiropractors would use similar methods (frequency and length of treatment, manipulation technique, and exercise) in the treatment of patients with adolescent idiopathic scoliosis. A high response rate to a national survey can be achieved through use of telephone contact.

Tackling the harm associated with acute kidney injury (AKI) is a global priority. In England, a national computerised AKI algorithm is being introduced across the National Health Service (NHS) to drive this change. The study sought to maximise its clinical utility and minimise the potential for burden on clinicians and patients in primary care. An appropriateness ratings evaluation using the RAND/UCLA Appropriateness Method. Clinical scenarios were developed to test the timeliness in (1) communication of AKI warning stage test results from clinical pathology services to primary care, and (2) primary care clinician response to an AKI warning stage test result. A 10-person panel was purposively sampled with representation from clinical biochemistry, acute and emergency medicine and general practice. General practitioners (GPs) represented typical practice in relation to rural and urban practice, out of hours care, GP commissioning and those interested in reducing the impact of medicalisation and 'overdiagnosis'. There was agreement that delivery of AKI warning stage test results through interruptive methods of communication (ie, telephone) from laboratories to primary care was the appropriate next step for patients with an AKI warning stage 3 test result. In the context of acute illness, waiting up to 72 hours to respond to an AKI warning stage test result was deemed an inappropriate action in 62 out of the 65 (94.5%) cases. There was agreement that a clinician response was required within 6 hours, or less, in 39 out of 40 (97.5%) clinical cases relating AKI warning stage test results in the presence of moderate hyperkalaemia. The study has informed national guidance to support a timely and calibrated response to AKI warning stage test results for adults in primary care. Further research is needed to support effective implementation, with a view to examine the effect on health outcomes and costs. Published by the BMJ Publishing Group Limited.

The United States appears to be the only country which typically requires completion of a two-year postdoctoral fellowship for one to be considered competent to practice clinical neuropsychology. We review the history of how this came to be in the United States. Further, we describe obstacles that postdoctoral trainees face during this stage of training. We first describe the most significant events leading to the requirement of a two-year fellowship in clinical neuropsychology. Next, we describe factors that trainees face when selecting and completing postdoctoral training. Finally, we review the results of the most recent annual survey of applicants for postdoctoral training to measure their experiences. Postdoctoral training in the United States is a relatively recent requirement in neuropsychology. Trainees face many obstacles when obtaining a postdoctoral position some of which can be addressed by the field. Training in Clinical Neuropsychology in the United States has evolved considerably over at least the last 45 or so years to the point that a two-year postdoctoral fellowship is now required for one to be a candidate for board certification through the American Board of Clinical Neuropsychology. We review many of the challenges that postdoctoral trainees face and provide survey data to describe their experiences and preferences.

The analysis of verbal interaction sequences in dyadic clinical communication: a review of methods.

2009-05-01

To identify methods available for sequential analysis of dyadic verbal clinical communication and to review their methodological and conceptual differences. Critical review, based on literature describing sequential analyses of clinical and other relevant social interaction. Dominant approaches are based on analysis of communication according to its precise position in the series of utterances that constitute event-coded dialogue. For practical reasons, methods focus on very short-term processes, typically the influence of one party's speech on what the other says next. Studies of longer-term influences are rare. Some analyses have statistical limitations, particularly in disregarding heterogeneity between consultations, patients or practitioners. Additional techniques, including ones that can use information about timing and duration of speech from interval-coding are becoming available. There is a danger that constraints of commonly used methods shape research questions and divert researchers from potentially important communication processes including ones that operate over a longer-term than one or two speech turns. Given that no one method can model the complexity of clinical communication, multiple methods, both quantitative and qualitative, are necessary. Broadening the range of methods will allow the current emphasis on exploratory studies to be balanced by tests of hypotheses about clinically important communication processes.

The use of control groups in music therapy research: a content analysis of articles in the Journal of Music Therapy.

The use of a control group is fundamental to experimental research design, though the use with clinical populations must be carefully considered. The purpose of this research was to examine the use of control groups in research with clinical and nonclinical populations published in Journal of Musical Therapy from 1964 through 2004. Criteria for inclusion were music or music therapy as an independent variable applied to one or more groups and at least one control group that did not receive a music treatment. Control groups were qualified as alternative treatment, placebo, no contact, and treatment as usual. Of the 692 articles, 94 met these criteria, 62 clinical and 32 nonclinical, representing 13.5% of the publications. Results indicated that research with clinical populations involved a mean of 38.1 subjects typically divided into two groups, an experimental and a control group. The pretest-posttest design was the most common (55%) as was a treatment as usual control group (45%). These design methods maximized the impact of the experimental music treatment on outcome. Experimental music groups significantly improved over control groups in the vast majority of studies identified. Undoubtedly, the foundation for evidence-based clinical practice is firm.

Patient similarity for precision medicine: a systematic review.

Evidence-based medicine is the most prevalent paradigm adopted by physicians. Clinical practice guidelines typically define a set of recommendations together with eligibility criteria that restrict their applicability to a specific group of patients. The ever-growing size and availability of health-related data is currently challenging the broad definitions of guideline-defined patient groups. Precision medicine leverages on genetic, phenotypic, or psychosocial characteristics to provide precise identification of patient subsets for treatment targeting. Defining a patient similarity measure is thus an essential step to allow stratification of patients into clinically-meaningful subgroups. The present review investigates the use of patient similarity as a tool to enable precision medicine. 279 articles were analyzed along four dimensions: data types considered, clinical domains of application, data analysis methods, and translational stage of findings. Cancer-related research employing molecular profiling and standard data analysis techniques such as clustering constitute the majority of the retrieved studies. Chronic and psychiatric diseases follow as the second most represented clinical domains. Interestingly, almost one quarter of the studies analyzed presented a novel methodology, with the most advanced employing data integration strategies and being portable to different clinical domains. Integration of such techniques into decision support systems constitutes and interesting trend for future research. Copyright © 2018. Published by Elsevier Inc.

To examine clinical outcomes in Asian patients with schizophrenia receiving monotherapy with olanzapine, risperidone or typical antipsychotics in naturalistic settings. In this report, data from the first 12 months of the prospective, observational, 3-year Intercontinental Schizophrenia Outpatient Health Outcomes study are presented for patients from participating Asian countries (Korea, Taiwan and Malaysia) who were started on, or switched to, monotherapy with olanzapine (n = 484), risperidone (n = 287) or a typical antipsychotic drug (n = 127) at baseline. At 12 months, overall reduction in the score of Clinical Global Impressions-Severity of Illness rating scale was greatest with olanzapine (p < 0.001 vs typical agents), followed by risperidone (p = 0.007 vs typical agents) treatment. Olanzapine treatment was found to have significantly better effects than typical agents on negative and depressive symptom scores, and significantly greater improvements than risperidone on negative and cognitive symptoms. The occurrence of extrapyramidal symptoms was least likely with olanzapine (p < 0.001 vs typical agents, and p = 0.012 vs risperidone), while the estimated odds of tardive dyskinesia were greatest in the typical treatment group (p = 0.046 vs olanzapine, and p = 0.082 vs risperidone). Mean weight increase was greater for olanzapine-treated patients compared with the other agents (p = 0.030 vs typical agents and p < 0.001 vs risperidone). The risk of menstrual disturbance was relatively high with risperidone when compared with olanzapine treatment (p < 0.001). The results of this observational study indicate that, in Asian patients with schizophrenia, olanzapine may offer benefits when compared with typical agents or risperidone. However, the significantly greater odds of weight gain should be considered in the clinical management of olanzapine-treated patients.

Case studies in two typical UK veterinary practices were undertaken to explore teamwork, including interprofessional working. Each study involved one week of whole team observation based on practice locations (reception, operating theatre), one week of shadowing six focus individuals (veterinary surgeons, veterinary nurses and administrators) and a final week consisting of semistructured interviews regarding teamwork. Errors emerged as a finding of the study. The definition of errors was inclusive, pertaining to inputs or omitted actions with potential adverse outcomes for patients, clients or the practice. The 40 identified instances could be grouped into clinical errors (dosing/drugs, surgical preparation, lack of follow-up), lost item errors, and most frequently, communication errors (records, procedures, missing face-to-face communication, mistakes within face-to-face communication). The qualitative nature of the study allowed the underlying cause of the errors to be explored. In addition to some individual mistakes, system faults were identified as a major cause of errors. Observed examples and interviews demonstrated several challenges to interprofessional teamworking which may cause errors, including: lack of time, part-time staff leading to frequent handovers, branch differences and individual veterinary surgeon work preferences. Lessons are drawn for building better veterinary teams and implications for Disciplinary Proceedings considered. British Veterinary Association.

Dysfunctional metacognition and drive for thinness in typical and atypical anorexia nervosa.

Anorexia nervosa is complex and difficult to treat. In cognitive therapies the focus has been on cognitive content rather than process. Process-oriented therapies may modify the higher level cognitive processes of metacognition, reported as dysfunctional in adult anorexia nervosa. Their association with clinical features of anorexia nervosa, however, is unclear. With reclassification of anorexia nervosa by DSM-5 into typical and atypical groups, comparability of metacognition and drive for thinness across groups and relationships within groups is also unclear. Main objectives were to determine whether metacognitive factors differ across typical and atypical anorexia nervosa and a non-clinical community sample, and to explore a process model by determining whether drive for thinness is concurrently predicted by metacognitive factors. Women receiving treatment for anorexia nervosa (n = 119) and non-clinical community participants (n = 100), aged between 18 and 46 years, completed the Eating Disorders Inventory (3(rd) Edition) and Metacognitions Questionnaire (Brief Version). Body Mass Index (BMI) of 18.5 kg/m(2) differentiated between typical (n = 75) and atypical (n = 44) anorexia nervosa. Multivariate analyses of variance and regression analyses were conducted. Metacognitive profiles were similar in both typical and atypical anorexia nervosa and confirmed as more dysfunctional than in the non-clinical group. Drive for thinness was concurrently predicted in the typical patients by the metacognitive factors, positive beliefs about worry, and need to control thoughts; in the atypical patients by negative beliefs about worry and, inversely, by cognitive self-consciousness, and in the non-clinical group by cognitive self-consciousness. Despite having a healthier weight, the atypical group was as severely affected by dysfunctional metacognitions and drive for thinness as the typical group. Because metacognition concurrently predicted drive for thinness in both groups, a role for process-oriented therapy in adults is suggested. Implications are discussed.

The model of Bobath clinical practice provides a framework identifying the unique aspects of the Bobath concept in terms of contemporary neurological rehabilitation. The utilisation of a framework to illustrate the clinical application of the Bobath concept provides the basis for a common understanding with respect to Bobath clinical practice, education, and research. The development process culminating in the model of Bobath clinical practice is described. The use of the model in clinical practice is illustrated using two cases: a client with a chronic incomplete spinal cord injury and a client with a stroke. This article describes the clinical application of the Bobath concept in terms of the integration of posture and movement with respect to the quality of task performance, applying the Model of Bobath Clinical Practice. Facilitation, a key aspect of Bobath clinical practice, was utilised to positively affect motor control and perception in two clients with impairment-related movement problems due to neurological pathology and associated activity limitations and participation restrictions - the outcome measures used to reflect the individual clinical presentation.

Intestinal Behçet disease (intestinal BD) and inflammatory bowel disease (IBD) share a lot of characteristics, including genetic background, clinical manifestations, and therapeutic strategies, especially the extraintestinal manifestations, such as oral ulcers, arthralgia, eye lesions, skin lesions, etc, but the coexistence of these 2 diseases are uncommon. Behçet disease with gastrointestinal involvement in ulcerative colitis (UC) patient has been reported in just 1 previous case report, but, which can not be diagnosed as definite intestinal BD based on Korean novel diagnositic criteria due to lacking the typical ileocecal ulcer. We present a 23-year-old woman with ulcerative disease who developed typical intestinal BD, which is the first case report of patient with coexisting UC and typical intestinal BD. This patient was diagnosed as coexistence of intestinal BD and UC base on the clinical manifestations, extra intestinal manifestations and typical colonoscopic findings. Steroid and methotrexate were administered. This patient achieved clinical remission and mucosal healing. Coexistence of intestinal BD and UC is uncommon, and the combination with steroid, methotrexate, and 5-aminosalicylic acids is an effective therapy.

Mathematics Competency for Beginning Chemistry Students Through Dimensional Analysis.

Mathematics competency in nursing education and practice may be addressed by an instructional variation of the traditional dimensional analysis technique typically presented in beginning chemistry courses. The authors studied 73 beginning chemistry students using the typical dimensional analysis technique and the variation technique. Student quantitative problem-solving performance was evaluated. Students using the variation technique scored significantly better (18.3 of 20 points, p < .0001) on the final examination quantitative titration problem than those who used the typical technique (10.9 of 20 points). American Chemical Society examination scores and in-house assessment indicate that better performing beginning chemistry students were more likely to use the variation technique rather than the typical technique. The variation technique may be useful as an alternative instructional approach to enhance beginning chemistry students' mathematics competency and problem-solving ability in both education and practice.

2001-07-01

Edgar Buchanan, D.D.S., pursued a diverse mix of careers during his lifetime: as he practiced dentistry, he also worked as a popular film and television actor. Although he eventually relinquished a full-time dental practice for acting, he continued his commitment to clinical dentistry. Acting in 100 films and four television series across a 35-year span (1939-1975). He personified a scheming, yet well-meaning rustic who specialized in "cracker-barrel" philosophy. Typically, he was cast in classic western movies as a bewhiskered character actor. In several films he played a frontier dentist who was always portrayed in a sympathetic and authentic manner. His unique gravelly voice, subtle facial expressions, folksy mannerisms and portly build enabled Buchanan to step into a wide variety of character roles. His most memorable television role was in the classic situation comedy, "Petticoat Junction," (1963-1970), where he played Uncle Joe, a folksy, lovable, free-loader whose many entertaining schemes created chaos.

Cluster analysis reveals subclinical subgroups with shared autistic and schizotypal traits.

2018-07-01

Autism and schizophrenia spectrum research is typically based on coarse diagnostic classification, which overlooks individual variation within clinical groups. This method limits the identification of underlying cognitive, genetic and neural correlates of specific symptom dimensions. This study, therefore, aimed to identify homogenous subclinical subgroups of specific autistic and schizotypal traits dimensions, that may be utilised to establish more effective diagnostic and treatment practices. Latent profile analysis of subscale scores derived from an autism-schizotypy questionnaire, completed by 1678 subclinical adults aged 18-40 years (1250 females), identified a local optimum of eight population clusters: High, Moderate and Low Psychosocial Difficulties; High, Moderate and Low Autism-Schizotypy; High Psychosis-Proneness; and Moderate Schizotypy. These subgroups represent the convergent and discriminant dimensions of autism and schizotypy in the subclinical population, and highlight the importance of examining subgroups of specific symptom characteristics across these spectra in order to identify the underlying genetic and neural correlates that can be utilised to advance diagnostic and treatment practices.

The purpose of this study was to describe barriers and facilitators to implementing a transitional care intervention for cognitively impaired older adults and their caregivers lead by advanced practice nurses (APNs). APNs implemented an evidence-based protocol to optimize transitions from hospital to home. An exploratory, qualitative directed content analysis examined 15 narrative case summaries written by APNs and fieldnotes from biweekly case conferences. Three central themes emerged: patients and caregivers having the necessary information and knowledge, care coordination, and the caregiver experience. An additional category was also identified, APNs going above and beyond. APNs implemented individualized approaches and provided care that exceeds the type of care typically staffed and reimbursed in the American health care system by applying a Transitional Care Model, advanced clinical judgment, and doing whatever was necessary to prevent negative outcomes. Reimbursement reform as well as more formalized support systems and resources are necessary for APNs to consistently provide such care to patients and their caregivers during this vulnerable time of transition.

To investigate usefulness of adherence to gastro-esophageal reflux disease (GERD) guideline established by the Spanish Association of Gastroenterology. Prospective, observational and multicentre study of 301 patients with typical symptoms of GERD who should be managed in accordance with guidelines and were attended by gastroenterologists in daily practice. Patients (aged > 18 years) were eligible for inclusion if they had typical symptoms of GERD (heartburn and/or acid regurgitation) as the major complaint in the presence or absence of accompanying atypical symptoms, such as dyspeptic symptoms and/or supraesophageal symptoms. Diagnostic and therapeutic decisions should be made based on specific recommendations of the Spanish clinical practice guideline for GERD which is a widely disseminated and well known instrument among Spanish in digestive disease specialists. Endoscopy was indicated in 123 (41%) patients: 50 with alarm symptoms, 32 with age > 50 years without alarm symptom. Seventy-two patients (58.5%) had esophagitis (grade A, 23, grade B, 28, grade C, 18, grade D, 3). In the presence of alarm symptoms, endoscopy was indicated consistently with recommendations in 98% of cases. However, in the absence of alarm symptoms, endoscopy was indicated in 33% of patients > 50 years (not recommended by the guideline). Adherence for proton pump inhibitors (PPIs) therapy was 80%, but doses prescribed were lower (half) in 5% of cases and higher (double) in 15%. Adherence regarding duration of PPI therapy was 69%; duration was shorter than recommended in 1% (4 wk in esophagitis grades C-D) or longer in 30% (8 wk in esophagitis grades A-B or in patients without endoscopy). Treatment response was higher when PPI doses were consistent with guidelines, although differences were not significant (95% vs 85%). GERD guideline compliance was quite good although endoscopy was over indicated in patients > 50 years without alarm symptoms; PPIs were prescribed at higher doses and longer duration.

Transcranial magnetic stimulation--may be useful as a preoperative screen of motor tract function.

Transcranial motor stimulation with noninvasive cortical surface stimulation, using a high-intensity magnetic field referred to as transcranial magnetic stimulation generally, is considered a nonpainful technique. In contrast, transcranial electric stimulation of the motor tracts typically cannot be done in unanesthesized patients. Intraoperative monitoring of motor tract function with transcranial electric stimulation is considered a standard practice in many institutions for patients during surgical procedures in which there is potential risk of motor tract impairment so that the risk of paraplegia or paraparesis can be reduced. Because transcranial electric stimulation cannot be typically done in the outpatient setting, transcranial magnetic stimulation may be able to provide a well-tolerated method for evaluation of the corticospinal motor tracts before surgery. One hundred fifty-five patients aged 5 to 20 years were evaluated preoperatively with single-stimulation nonrepetitive transcranial magnetic stimulation for preoperative assessment. The presence of responses to transcranial magnetic stimulation reliably predicted the presence of responses to transcranial electric stimulation intraoperatively. No complications occurred during the testing, and findings were correlated to the clinical history and used in the setup of the surgical monitoring.

Participants in clinical trials of spinal manipulation have not been rigorously blinded to group assignment. This study reports on secondary analyses of the retention of participant blinding beyond the immediate posttreatment time frame following a single-session, randomized clinical study. A novel control cervical manipulation procedure that has previously been shown to be therapeutically inert was contrasted with a typical manipulation procedure. A randomized clinical study of a single session of typical vs sham-control manipulation in patients with chronic neck pain was conducted. Findings of self-reported group registration at 24 to 48 hours posttreatment were computed. The Blinding Index (BI) of Bang et al was then applied to both the immediate and post-24- to 48-hour results. Twenty-four to 48 hours after treatment, 94% and 22% of participants in the typical and control groups, respectively, correctly identified their group assignment. When analyzed with the BI of Bang et al, the immediate posttreatment BI for the group receiving a typical manipulation was 0.22 (95% confidence interval [CI], -0.03 to 0.47); for the group receiving a control manipulation, it was 0.19 (95% CI, -0.06 to 0.43). The BI at post-24 hours was as follows: typical = 0.75 (95% CI, 0.59-0.91) and control = -0.34 (95% CI, -0.58 to -0.11). This study found that the novel sham-control cervical manipulation procedure may be effective in blinding sham group allocation up to 48 hours posttreatment. It appears that, at 48 hours posttreatment, the modified form of the typical cervical manipulation was not. The sham-control procedure appears to be a promising procedure for future clinical trials. © 2013. Published by National University of Health Sciences All rights reserved.

The influence of a novel simulated learning environment upon student clinical subjective refraction performance: A pilot study.

Woodman-Pieterse, Emily C; De Souza, Neilsen J; Vincent, Stephen J

2016-07-01

Optometry students are taught the process of subjective refraction through lectures and laboratory-based practicals before progressing to supervised clinical practice. Simulated leaning environments (SLEs) form part of an emerging technology used in a range of health disciplines; however, there is limited evidence regarding the effectiveness of clinical simulators as educational tools. Forty optometry students (20 fourth year and 20 fifth year) were assessed twice by a qualified optometrist (two examinations separated by four to eight weeks), while completing a monocular non-cycloplegic subjective refraction on the same patient with an unknown refractive error, simulated using contact lenses. Half of the students were granted access to an online simulated learning environment, The Brien Holden Vision Institute (BHVI) Virtual Refractor, and the remaining students formed a control group. The primary outcome measures at each visit were; accuracy of the clinical refraction compared to a qualified optometrist and relative to the Optometry Council of Australia and New Zealand (OCANZ) subjective refraction examination criteria. Secondary measures of interest included descriptors of student SLE engagement, student self-reported confidence levels and correlations between performance in the simulated and real-world clinical environment. Eighty per cent of students in the intervention group interacted with the simulated learning environment (for an average of 100 minutes); however, there was no correlation between measures of student engagement with the BHVI Virtual Refractor and speed or accuracy of clinical subjective refractions. Fifth year students were typically more confident and refracted more accurately and more quickly than fourth year students. A year group by experimental group interaction (p = 0.03) was observed for accuracy of the spherical component of refraction and post hoc analysis revealed that less experienced students exhibited greater gains in clinical accuracy following exposure to the SLE intervention. Short-term exposure to a SLE can positively influence clinical subjective refraction outcomes for less experienced optometry students and may be of benefit in increasing the skills of novice refractionists to levels appropriate for commencing supervised clinical interactions. © 2016 Optometry Australia.

Successful treatment of suspected organizing pneumonia in a patient without typical imaging and pathological characteristic: A case report.

Organizing pneumonia (OP) is a clinicopathological entity characterized by granulation tissue plugs in the lumen of small airways, alveolar ducts, and alveoli. Diagnosis of OP needs the combination of clinical features, imaging and pathology. But it occurs often that there are no typical pathological features to support the diagnosis, which poses a challenge for clinicians' diagnosis and treatment. We diagnosed a case of OP without typical imaging and pathological characteristic and treated successfully. Finally we confirmed the pathological diagnosis. Not every OP case is supported by pathological evidence and typical imaging changes. It is important for us to judge and decide the diagnosis according to clinical experience.

Molecular genetic testing for hereditary hemochromatosis (HH) is recognized as a reference test to confirm the diagnosis of suspected HH or to predict its risk. The vast majority (typically >90%) of patients with clinically characterized HH are homozygous for the p.C282Y variant in the HFE gene, referred to as HFE-related HH. Since 1996, HFE genotyping was implemented in diagnostic algorithms for suspected HH, allowing its early diagnosis and prevention. However, the penetrance of disease in p.C282Y homozygotes is incomplete. Hence, homozygosity for p.C282Y is not sufficient to diagnose HH. Neither is p.C282Y homozygosity required for diagnosis as other rare forms of HH exist, generally referred to as non-HFE-related HH. These pose significant challenges when defining criteria for referral, testing protocols, interpretation of test results and reporting practices. We present best practice guidelines for the molecular genetic diagnosis of HH where recommendations are classified, as far as possible, according to the level and strength of evidence. For clarification, the guidelines' recommendations are preceded by a detailed description of the methodology and results obtained with a series of actions taken in order to achieve a wide expert consensus, namely: (i) a survey on the current practices followed by laboratories offering molecular diagnosis of HH; (ii) a systematic literature search focused on some identified controversial topics; (iii) an expert Best Practice Workshop convened to achieve consensus on the practical recommendations included in the guidelines.

Ad hoc supervision of general practice registrars as a 'community of practice': analysis, interpretation and re-presentation.

Clement, T; Brown, J; Morrison, J; Nestel, D

2016-05-01

General practice registrars in Australia undertake most of their vocational training in accredited general practices. They typically see patients alone from the start of their community-based training and are expected to seek timely ad hoc support from their supervisor. Such ad hoc encounters are a mechanism for ensuring patient safety, but also provide an opportunity for learning and teaching. Wenger's (Communities of practice: learning, meaning, and identity. Cambridge University Press, New York, 1998) social theory of learning ('communities of practice') guided a secondary analysis of audio-recordings of ad hoc encounters. Data from one encounter is re-presented as an extended sequence to maintain congruence with the theoretical perspective and enhance vicariousness. An interpretive commentary communicates key features of Wenger's theory and highlights the researchers' interpretations. We argue that one encounter can reveal universal understandings of clinical supervision and that the process of naturalistic generalisation allows readers to transfer others' experiences to their own contexts. The paper raises significant analytic, interpretive, and representational issues. We highlight that report writing is an important, but infrequently discussed, part of research design. We discuss the challenges of supporting the learning and teaching that arises from adopting a socio-cultural lens and argue that such a perspective importantly captures the complex range of issues that work-based practitioners have to grapple with. This offers a challenge to how we research and seek to influence work-based learning and teaching in health care settings.

To (1) identify and summarize procedures of Foxx and Azrin's classic toilet training protocol that continue to be used in training typically developing children and (2) adapt recent findings with the original Foxx and Azrin procedures to inform practical suggestions for the rapid toilet training of typically developing children in the primary care setting. Literature searches of PsychINFO and MEDLINE databases used the search terms "(toilet* OR potty* AND train*)." Selection criteria were only peer-reviewed experimental articles that evaluated intensive toilet training with typically developing children. Exclusion criteria were (1) nonpeer reviewed research, (2) studies addressing encopresis and/or enuresis, (3) studies excluding typically developing children, and (4) studies evaluating toilet training during infancy. In addition to the study of Foxx and Azrin, only 4 publications met the above criteria. Toilet training procedures from each article were reviewed to determine which toilet training methods were similar to components described by Foxx and Azrin. Common training elements include increasing the frequency of learning opportunities through fluid loading and having differential consequences for being dry versus being wet and for voiding in the toilet versus elsewhere. There is little research on intensive toilet training of typically developing children. Practice sits and positive reinforcement for voids in the toilet are commonplace, consistent with the Foxx and Azrin protocol, whereas positive practice as a corrective procedure for wetting accidents often is omitted. Fluid loading and differential consequences for being dry versus being wet and for voiding in the toilet also are suggested procedures, consistent with the Foxx and Azrin protocol.

This study evaluated the effects of massed and distributed practice on the acquisition of tacts and textual behavior in typically developing children. We compared the effects of massed practice (i.e., consolidating all practice opportunities during the week into a single session) and distributed practice (i.e., distributing all practice opportunities across 4 sessions during the week) on the acquisition of textual behavior in English, tacting pictures of common nouns in Spanish, and textual behavior in Spanish using an adapted alternating treatments design embedded within a multiple probe design. We also examined correct responding during probes that (a) excluded prompts and reinforcement and (b) occurred 48 hr after training each week. The results indicated that distributed practice was the more efficient training format. Maintenance data collected up to 4 weeks after training also indicated that the participants consistently displayed higher levels of correct responding to targets that had been trained in distributed format. We discuss implications for practice and potential areas for future research. © Society for the Experimental Analysis of Behavior.

Evidence based practice in clinical physiotherapy education: a qualitative interpretive description.

Olsen, Nina R; Bradley, Peter; Lomborg, Kirsten; Nortvedt, Monica W

2013-04-11

Health care undergraduate students are expected to practice evidence-based after they graduate. Previous research indicates that students face several problems with transferring evidence-based practice to real patient situations. Few studies have explored reasons for this. The aim of this study was to explore beliefs, experiences and attitudes related to third year students' use of evidence-based practice in clinical physiotherapy education among students, clinical instructors and visiting teachers. In total, six focus group interviews were conducted: three with 16 students, two with nine clinical instructors and one with four visiting teachers. In addition, one individual interview and one interview in a pair were conducted with clinical instructors. Interviewing three different participant-categories ensured comparative analysis and enabled us to exploit differences in perspectives and interactions. Interpretive description guided this process. Four integrative themes emerged from the analysis: "attempt to apply evidence-based practice", "novices in clinical practice", "prioritize practice experience over evidence-based practice" and "lack role models in evidence-based practice". Students tried to search for research evidence and to apply this knowledge during clinical placements; a behaviour that indicated a positive attitude towards evidence-based practice. At the same time, students were novices and required basic background information more than research information. As novices they tended to lean on their clinical instructors, and were more eager to gain practical experience than practicing evidence-based; a behaviour that clinical instructors and visiting teachers often supported. Students noticed a lack of an EBP culture. Both students and clinical instructors perceived a need for role models in evidence-based practice. Clinical instructors are in a position to influence students during clinical education, and thus, important potential role models in evidence-based practice. Actions from academic and clinical settings are needed to improve competence in evidence-based practice among clinical instructors, and future research is needed to investigate the effect of such efforts on students' behaviour.

To determine prognostic factors of clinically relevant radiographic progression (CRRP) in patients with rheumatoid arthritis (RA) in clinical practice.We performed a multicenter prospective study in Japan of biological disease-modifying antirheumatic drug (bDMARD)-naive RA patients with moderate to high disease activity treated with conventional synthetic DMARDs (csDMARDs) at study entry. We longitudinally observed 408 patients for 1 year and assessed disease activity every 3 months. CRRP was defined as yearly progression of modified total Sharp score (mTSS) > 3.0 U. We also divided the cohort into 2 groups based on disease duration (<3 vs ≥3 years) and performed a subgroup analysis.CRRP was found in 10.3% of the patients. A multiple logistic regression analysis revealed that the independent variables to predict the development of CRRP were: CRP at baseline (0.30 mg/dL increase, 95% confidence interval [CI] 1.01-1.11), time-integrated Disease Activity Score in 28 joints-erythrocyte sedimentation rate (DAS28-ESR) during the 1 year postbaseline (12.4-unit increase, 95%CI 1.17-2.59), RA typical erosion at baseline (95%CI 1.56-21.1), and the introduction of bDMARDs (95%CI 0.06-0.38). The subgroup analysis revealed that time-integrated DAS28-ESR is not a predictor whereas the introduction of bDMARDs is a significant protective factor for CRRP in RA patients with disease duration <3 years.We identified factors that could be used to predict the development of CRRP in RA patients treated with DMARDs. These variables appear to be different based on the RA patients' disease durations.

Study design and data analysis considerations for the discovery of prognostic molecular biomarkers: a case study of progression free survival in advanced serous ovarian cancer.

Accurate discovery of molecular biomarkers that are prognostic of a clinical outcome is an important yet challenging task, partly due to the combination of the typically weak genomic signal for a clinical outcome and the frequently strong noise due to microarray handling effects. Effective strategies to resolve this challenge are in dire need. We set out to assess the use of careful study design and data normalization for the discovery of prognostic molecular biomarkers. Taking progression free survival in advanced serous ovarian cancer as an example, we conducted empirical analysis on two sets of microRNA arrays for the same set of tumor samples: arrays in one set were collected using careful study design (that is, uniform handling and randomized array-to-sample assignment) and arrays in the other set were not. We found that (1) handling effects can confound the clinical outcome under study as a result of chance even with randomization, (2) the level of confounding handling effects can be reduced by data normalization, and (3) good study design cannot be replaced by post-hoc normalization. In addition, we provided a practical approach to define positive and negative control markers for detecting handling effects and assessing the performance of a normalization method. Our work showcased the difficulty of finding prognostic biomarkers for a clinical outcome of weak genomic signals, illustrated the benefits of careful study design and data normalization, and provided a practical approach to identify handling effects and select a beneficial normalization method. Our work calls for careful study design and data analysis for the discovery of robust and translatable molecular biomarkers.

Advances in osteoporosis (OP)case definition, treatment options, optimal therapy duration and pharmacoeconomic evidence in the national context motivated the Portuguese Society of Rheumatology (SPR) to update the Portuguese recommendations for the diagnosis and management of osteoporosis published in 2007. SPR bone diseases' working group organized meetings involving 55 participants (rheumatologists, rheumatology fellows and one OP specialist nurse) to debate and develop the document. First, the working group selected 11 pertinent clinical questions for the diagnosis and management of osteoporosis in standard clinical practice. Then, each question was investigated through literature review and draft recommendations were built through consensus. When insufficient evidence was available, recommendations were based on experts' opinion and on good clinical practice. At two national meetings, the recommendations were discussed and updated. A draft of the recommendations full text was submitted to critical review among the working group and suggestions were incorporated. A final version was circulated among all Portuguese rheumatologists before publication and the level of agreement was anonymously assessed using an online survey. The 2018 SPR recommendations provide comprehensive guidance on osteoporosis prevention, diagnosis, fracture risk assessment, pharmacological treatment initiation, therapy options and duration of treatment, based on the best available evidence. They attained desirable agreement among Portuguese rheumatologists. As more evidence becomes available, periodic revisions will be performed. Target audience and patient population: The target audience for these guidelines includes all clinicians. The target patient population includes adult Portuguese people. Intended use: These recommendations provide general guidance for typical cases. They may not be appropriate in all situations - clinicians are encouraged to consider this information together with updated evidence and their best clinical judgment in individual cases.

Background Peanut allergy is relatively common, typically permanent, and often severe. Double-blind, placebo-controlled food challenge is considered the gold standard for the diagnosis of food allergy–related disorders. However, the complexity and potential of double-blind, placebo-controlled food challenge to cause life-threatening allergic reactions affects its clinical application. A laboratory test that could accurately diagnose symptomatic peanut allergy would greatly facilitate clinical practice. Objective We sought to develop an allergy diagnostic method that could correctly predict symptomatic peanut allergy by using peptide microarray immunoassays and bioinformatic methods. Methods Microarray immunoassays were performed by using the sera from 62 patients (31 with symptomatic peanut allergy and 31 who had outgrown their peanut allergy or were sensitized but were clinically tolerant to peanut). Specific IgE and IgG4 binding to 419 overlapping peptides (15 mers, 3 offset) covering the amino acid sequences of Ara h 1, Ara h 2, and Ara h 3 were measured by using a peptide microarray immunoassay. Bioinformatic methods were applied for data analysis. Results Individuals with peanut allergy showed significantly greater IgE binding and broader epitope diversity than did peanut-tolerant individuals. No significant difference in IgG4 binding was found between groups. By using machine learning methods, 4 peptide biomarkers were identified and prediction models that can predict the outcome of double-blind, placebo-controlled food challenges with high accuracy were developed by using a combination of the biomarkers. Conclusions In this study, we developed a novel diagnostic approach that can predict peanut allergy with high accuracy by combining the results of a peptide microarray immunoassay and bioinformatic methods. Further studies are needed to validate the efficacy of this assay in clinical practice. PMID:22444503

Interstitial granulomatous dermatitis with arthritis (IGDA), also known as Ackerman's syndrome, is a rare cutaneous disease classically characterized by the triad of cutaneous cords, a typical histologic infiltrate mainly constituted by histiocytes and arthritis/connective tissue disease. Here we report the case of IGDA with the typical clinical and histological features in a patient affected by lupus erythematosus. In this article we underline that IGDA may have a variety of different clinical and histological features. The rope sign is typical but infrequent, while histology is usually characteristic and shows a dermal inflammatory infiltrate, with a predominance of histiocytes, localized interstitially and in a palisaded array between collagen fibres, that show signs of degeneration. Clinical and histological differential diagnoses are discussed.

With the widespread use of information communication technologies, computerized clinical practice guidelines are developed and considered as effective decision supporting tools in assisting the processes of clinical activities. However, the development of computerized clinical practice guidelines in Taiwan is still at the early stage and acceptance level among major users (physicians) of computerized clinical practice guidelines is not satisfactory. This study aims to investigate critical factors influencing physicians' intention to computerized clinical practice guideline use through an integrative model of activity theory and the technology acceptance model. The survey methodology was employed to collect data from physicians of the investigated hospitals that have implemented computerized clinical practice guidelines. A total of 505 questionnaires were sent out, with 238 completed copies returned, indicating a valid response rate of 47.1 %. The collected data was then analyzed by structural equation modeling technique. The results showed that attitudes toward using computerized clinical practice guidelines (γ = 0.451, p < 0.001), organizational support (γ = 0.285, p < 0.001), perceived usefulness of computerized clinical practice guidelines (γ = 0.219, p < 0.05), and social influence (γ = 0.213, p < 0.05) were critical factors influencing physicians' intention to use computerized clinical practice guidelines, and these factors can explain 68.6 % of the variance in intention to use computerized clinical practice guidelines. This study confirmed that some subject (human) factors, environment (organization) factors, tool (technology) factors mentioned in the activity theory should be carefully considered when introducing computerized clinical practice guidelines. Managers should pay much attention on those identified factors and provide adequate resources and incentives to help the promotion and use of computerized clinical practice guidelines. Through the appropriate use of computerized clinical practice guidelines, the clinical benefits, particularly in improving quality of care and facilitating the clinical processes, will be realized.

Confronting Therapeutic Failure: A Conversation Guide

2015-01-01

We reflect on the impact of bad news on both clinician and patient in the setting of cancer treatment failure. We review the classic six-step SPIKES (setting, perception, invitation for information, knowledge, empathy, summarize and strategize) protocol for giving bad news that has been widely adopted since it was first published in this journal in 2005. The goal of such a conversation guide is to describe both the process and the tasks that constitute vital steps for clinicians and to comment on the emotional impact of the conversation on the clinician. Confronting therapeutic failure is the hardest task for oncologists. We offer practical tips derived from a thorough review of the evidence and our clinical experience. Implications for Practice: Discussing the failure of anticancer therapy remains a very difficult conversation for oncologists and their patients. In this article, the process of confronting this failure is broken down into various components, and practical tips are provided for clinicians following a classic protocol for breaking bad news. Also addressed are the emotions of the oncologist and the reasons why these conversations are typically so hard. These insights are based on solid research intended to deepen the therapeutic connection between physician and patient.

Tattooing the skin as a means of personal expression is a ritualized practice that has been around for centuries across many different cultures. Accordingly, the symbolic meaning of tattoos has evolved over time and is highly individualized, from both the internal perspective of the wearer and the external perspective of an observer. Within modern Western societies through the 1970s, tattoos represented a cultural taboo, typically associated with those outside of the mainstream such as soldiers, incarcerated criminals, gang members, and others belonging to marginalized and counter-cultural groups. This paper aims to review the more recent epidemiology of tattoos in Western culture in order to establish that tattooing has become a mainstream phenomenon. We then review psychological and psychiatric aspects of tattoos, with a goal of revising outmoded stigmas about tattooing and helping clinicians working with tattooed patients to facilitate an exploration of the personal meaning of skin art and self-identity. We suggest that as a kind of augmentation of the physical exam, looking at and talking to patients about their tattoos can provide a valuable window into the psyche, informing clinical practice.

One dramatic advance in human immunodeficiency virus (HIV) prevention efforts has been the prescription of medications typically used for HIV treatment as prophylaxis against acquiring HIV. As a preventative agent, this practice is referred to as “preexposure prophylaxis” (PrEP). The U.S. Federal Drug Administration approved daily PrEP for adults at risk for HIV who do not consistently use condoms during sex with HIV-infected or unknown-status partners. In this paper, we describe a cognitive-behavioral therapy (CBT) PrEP adherence intervention developed for use in high-risk sexual-minority men in the United States, adapted from “Life-Steps,” an evidence-based CBT intervention to promote adherence to HIV treatment. Modules include creating a PrEP dosing schedule, adhering to daily PrEP, problem solving barriers to adherence, and sexual risk-reduction techniques. Supplemented with practical video vignettes, this novel intervention may help to enhance the clinical practice of health care providers in outpatient settings to increase PrEP adherence in sexual-minority men.

Occipital neuralgia is a well-recognized cause of posterior head and neck pain that may associate mild sensory changes in the cutaneous distribution of the occipital nerves, lacking a recognizable local structural aetiology in most cases. Atypical clinical features or an abnormal neurological examination are alerts for a potential underlying cause of pain, although cases of clinically typical occipital neuralgia as isolated manifestation of lesions of the cervical spinal cord, cervical roots, or occipital nerves have been increasingly reported. We describe two cases (one with typical and another one with atypical clinical features) of occipital neuralgia secondary to paravertebral pyomyositis and vertebral relapse of multiple myeloma in patients with relevant medical history that aroused the possibility of an underlying structural lesion. We discuss the need for cranio-cervical magnetic resonance imaging in all patients with occipital neuralgia, even when typical clinical features are present and neurological examination is completely normal.

Abstract Introduction: Physical and mental changes associated with aging commonly lead to a decrease in communication capacity, reducing social interactions and increasing loneliness. Computer classes for older adults make significant contributions to social and cognitive aspects of aging. Games in a virtual reality (VR) environment stimulate the practice of communicative and cognitive skills and might also bring benefits to older adults. Furthermore, it might help to initiate their contact to the modern technology. The purpose of this study protocol is to evaluate the effects of practicing VR games during computer classes on the level of loneliness of students of an elderly reference center. Methods and Analysis: This study will be a prospective longitudinal study with a randomised cross-over design, with subjects aged 50 years and older, of both genders, spontaneously enrolled in computer classes for beginners. Data collection will be done in 3 moments: moment 0 (T0) – at baseline; moment 1 (T1) – after 8 typical computer classes; and moment 2 (T2) – after 8 computer classes which include 15 minutes for practicing games in VR environment. A characterization questionnaire, the short version of the Short Social and Emotional Loneliness Scale for Adults (SELSA-S) and 3 games with VR (Random, MoviLetrando, and Reaction Time) will be used. For the intervention phase 4 other games will be used: Coincident Timing, Motor Skill Analyser, Labyrinth, and Fitts. The statistical analysis will compare the evolution in loneliness perception, performance, and reaction time during the practice of the games between the 3 moments of data collection. Performance and reaction time during the practice of the games will also be correlated to the loneliness perception. Ethics and Dissemination: The protocol is approved by the host institution's ethics committee under the number 52305215.3.0000.0082. Results will be disseminated via peer-reviewed journal articles and conferences. This clinical trial is registered at ClinicalTrials.gov identifier: NCT02798081. PMID:28272198

Practice-based research should be performed in all practice settings if the results are to be applied to all settings. However, some practice settings, such as community clinics, have unique features that may make the conduct of such research more challenging. The purpose of this article is to describe and compare the similarities and unique challenges related to conducting research in community clinics compared to private practices within the Northwest Practice-Based REsearch Collaborative in Evidence-Based DENTistry (PRECEDENT) network. Information was obtained from meetings with general dentists, a survey of general dentists (N = 253), and a clinical examination and record review of a systemic random sample of patients visiting community clinics and private practices. (N = 1903)—all part of a dental practice-based research network. The processes of conducting research, the dentist and patient sociodemographic characteristics, the prevalence of oral diseases, and the dental treatments received in community clinics and private practices were compared. Both community clinics and private practices have the clinical treatment of the patients as their priority and have time constraints on research. The processes of research training, obtaining informed consent, and collecting, transmitting, and securely maintaining research data are also similar. The patient populations and treatment needs differ substantially between community clinics and private practices, with a higher prevalence of dental caries and higher restorative treatment needs in the community clinic patients. The process of study participant selection and follow-up for research and the dentist and staff work arrangements also vary between the two practice settings. Although community clinic patients and their dental healthcare providers have different research needs and challenges than their counterparts in private practice, practice-based research can be successfully PMID:25429251

Gait efficiency in children with cerebral palsy is decreased. To date, most research did not include the upper body as a separate functional unit when exploring these changes in gait efficiency. Since children with spastic diplegia often experience problems with trunk control, they could benefit from separate evaluation of the so-called 'passenger unit'. Therefore, the aim of the current study was to improve insights in the role of the passenger unit in decreased gait efficiency in children with diplegia. Mechanical cost of walking was investigated by calculating work by the integrated joint power approach in 18 children with diplegia and 25 age-related typical developing controls. The total mechanical work in children with diplegia was 1.5 times higher than in typical children. In children with diplegia work at the lower limbs was increased by 37% compared to typical children. Substantially higher increases, up to 222%, were noted at the passenger unit. Trunk and head were the main contributors to the increased work of the passenger unit, but the role of the arms cannot be neglected. Due to these disproportional increases in locomotor and passenger unit, the demands of the passenger unit in pathological gait can no longer be considered minor, as in typical gait. Therefore, the role of the passenger unit must be recognized in the decrease of gait efficiency in children with spastic diplegia and should be part of the evaluation of gait efficiency in clinical practice.

What does it take to change practice? Perspectives of pharmacists in Ontario.

Gregory, Paul A M; Teixeira, Beatriz; Austin, Zubin

This is a time of rapid change in the profession of pharmacy. Anecdotally, there are concerns that the pace, extent and rate of practice evolution are lagging. There is little evidence documenting the influencers and mechanisms that drive practice changes forward in pharmacy in Canada. An exploratory qualitative method was selected, using both one-on-one interviews with self-categorized typical pharmacists and larger focus groups to provide context and confirmation of themes generated through interviews. Data were analyzed and coded using a constant-comparative iterative method, in order to generate themes related to the factors influencing pharmacists to actually change their practice. A total of 46 pharmacists meeting inclusion criteria participated in this study in focus groups, interviews or both. Nine themes were identified: 1) permission, 2) process pointers, 3) practice/rehearsal, 4) positive reinforcement, 5) personalized attention, 6) peer referencing, 7) physician acceptance, 8) patients' expectations and 9) professional identity supportive of a truly clinical role. One theme that did not emerge was payment, or remuneration, as a specific or isolated motivational factor for change. The complexity of practice change in pharmacy and the multiple factors highlighted in this study point to a more deliberate and concerted effort being needed by diverse pharmacy organizations (educators, regulators, employers, professional associations, etc.) to support pharmacists through the change management process. The "9 Ps of practice change" identified through this study can provide pharmacists with guidance in terms of how to better support evolution of the profession in a more time-efficient and effective manner.

Gender differences in moral judgment and the evaluation of gender-specified moral agents.

PubMed

Capraro, Valerio; Sippel, Jonathan

2017-11-01

Whether, and if so, how exactly gender differences are manifested in moral judgment has recently been at the center of much research on moral decision making. Previous research suggests that women are more deontological than men in personal, but not impersonal, moral dilemmas. However, typical personal and impersonal moral dilemmas differ along two dimensions: Personal dilemmas are more emotionally salient than impersonal ones and involve a violation of Kant's practical imperative that humans must never be used as a mere means, but only as ends. Thus, it remains unclear whether the reported gender difference is due to emotional salience or to the violation of the practical imperative. To answer this question, we explore gender differences in three moral dilemmas: a typical personal dilemma, a typical impersonal dilemma, and an intermediate dilemma, which is not as emotionally salient as typical personal moral dilemmas, but contains an equally strong violation of Kant's practical imperative. While we replicate the result that women tend to embrace deontological ethics more than men in personal, but not impersonal, dilemmas, we find no gender differences in the intermediate situation. This suggests that gender differences in these type of dilemmas are driven by emotional salience, and not by the violation of the practical imperative. Additionally, we also explore whether people think that women should behave differently than men in these dilemmas. Across all three dilemmas, we find no statistically significant differences about how people think men and women should behave.

The relationship between dissociable components of autobiographical memory (e.g. semantic personality traits and episodic memory retrieval) and other cognitive skills that are proposed to enable one to develop a sense of self (e.g. introspection) have not previously been explored for children with autism spectrum disorder. This study compared autobiographical memory (semantic and episodic) and knowledge of self (internal/external self-knowledge and introspection/mentalising abilities) in children (aged 11-18 years) with high-functioning autism spectrum disorder and typically developing controls (total N = 48). Novel and standard tasks were employed. Compared to typically developing controls, young people with autism spectrum disorder had autobiographical memory difficulties that were characterised by a reduction in the retrieval of semantic personality traits, with more initial prompts required to facilitate episodic memory retrieval and fewer episodic memories containing emotional and sensory information. Knowledge of the self and others was also impaired, with reduced introspection and poorer mentalising abilities. Young people with autism spectrum disorder were also identified as presenting with an atypical relationship between autobiographical memory and self-knowledge, which was significantly different from typically developing controls. Test performance is discussed in relation to the functions of autobiographical memory, with consideration of how these cognitive difficulties may contribute to clinical practices and the social and behavioural characteristics of autism spectrum disorder.

Studies performed in the US and other Western countries have documented that physicians generate many clinical questions during a typical day and rely on various information sources for answers. Little is known about the information seeking behaviors of physicians practicing in other countries, particularly those with limited Internet connectivity. We conducted this study to document the perceived barriers to information resources used by medical residents in Iran. Our findings reveal that different perceived barriers exist for electronic versus paper-based resources. Notably, paper-based resources are perceived to be limited by resident time-constraints and availability of resources, whereas electronic resources are limited by cost decentralized resources (such as PDAs) and accessibility of centralized, Internet access. These findings add to the limited literature regarding health information-seeking activities in international healthcare settings, particularly those with limited Internet connectivity, and will supplement future studies of and interventions in such settings.

OBJECTIVE. To provide an example of an occupational therapy feasibility study and evaluate the implementation of a randomized controlled pilot and feasibility trial examining the impact of a sensory-adapted dental environment (SADE) to enhance oral care for children with autism spectrum disorder (ASD). METHOD. Twenty-two children with ASD and 22 typically developing children, ages 6–12 yr, attended a dental clinic in an urban hospital. Participants completed two dental cleanings, 3–4 mo apart, one in a regular environment and one in a SADE. Feasibility outcome measures were recruitment, retention, accrual, dropout, and protocol adherence. Intervention outcome measures were physiological stress, behavioral distress, pain, and cost. RESULTS. We successfully recruited and retained participants. Parents expressed satisfaction with research study participation. Dentists stated that the intervention could be incorporated in normal practice. Intervention outcome measures favored the SADE condition. CONCLUSION. Preliminary positive benefit of SADE in children with ASD warrants moving forward with a large-scale clinical trial. PMID:25871593

Mild traumatic brain injury (mTBI) reportedly occurs in 8-22% of U.S. servicemembers who conduct combat operations in Afghanistan and Iraq. The current definition for mTBI found in the medical literature, to include the Department of Defense (DoD) and Veterans Administration (VA) clinical practice guidelines is limited by the parameters of loss of consciousness, altered consciousness, or post-traumatic amnesia, and does not account for other constellations of potential symptoms. Although mTBI symptoms typically resolve within seven days, some servicemembers experience symptoms that continue for weeks, months, or years following an injury. Mild TBI is one of few disorders in medicine where a benign and misleading diagnostic classification is bestowed on patients at the time of injury, yet still can be associated with lifelong complications. This article comprehensively reviews the clinical literature over the past 20 years and proposes a new classification for TBI that addresses acute, sub-acute, and chronic phases, and includes neurocognitive, somatic, and psychological symptom presentation. 2011.

To assess US availability and use of measles-mumps-rubella (MMR) vaccination documentation for refugees vaccinated overseas. We selected 1500 refugee records from 14 states from March 2013 through July 2015 to determine whether overseas vaccination records were available at the US postarrival health assessment and integrated into the Advisory Committee on Immunization Practices schedule. We assessed number of doses, dosing interval, and contraindications. Twelve of 14 (85.7%) states provided data on 1118 (74.5%) refugees. Overseas records for 972 (86.9%) refugees were available, most from the Centers for Disease Control and Prevention's Electronic Disease Notification system (66.9%). Most refugees (829; 85.3%) were assessed appropriately for MMR vaccination; 37 (3.8%) should have received MMR vaccine but did not; 106 (10.9%) did not need the MMR vaccine but were vaccinated. Overseas documentation was available at most clinics, and MMR vaccinations typically were given when needed. Further collaboration between refugee health clinics and state immunization information systems would improve accessibility of vaccination documentation.

This chapter examines the perceptions and treatment of psychological combat reactions by American Indians. My goal is to provide the reader with an introduction to the clinical implications of these perceptions and treatment in order to encourage a closer examination of what American Indian healers have to offer mental health professionals trained in the mainstream (what I will refer to as Anglo) psychological tradition. To do this we shall briefly examine how American Indians regard war and the role of warriors, for this cultural perception influences how combat reactions such as posttraumatic stress disorder symptoms are perceived and treated. Regardless of the value of what we might learn from American Indian culture, it does not matter what they say if we will not hear. It is necessary to consider attitudes typically held toward the concepts and techniques of American Indian healing practices if we wish for this examination to be more than an anthropological exposition, and have clinical value for Anglo mental health professionals.

Reversal deterioration of renal function accompanied with primary hypothyrodism.

Dragović, Tamara

2012-02-01

Hypothyroidism is often accompanied with decline of kidney function, or inability to maintain electrolyte balance. These changes are usually overlooked in everyday practice. Early recognition of this association eliminates unnecessary diagnostic procedures that postpone the adequate treatment. Two patients with elevated serum creatinine levels due to primary autoimmune hypothyroidism, with complete recovery of creatinine clearance after thyroid hormone substitution therapy are presented. The first patient was a young male whose laboratory tests suggested acute renal failure, and the delicate clinical presentation of reduced thyroid function. The second patient was an elderly woman with a history of a long-term signs and symptoms attributed to ageing, including the deterioration of renal function, with consequently delayed diagnosis of hypothyroidism. Serum thyrotropin and thyroxin levels measurement should be done in all cases of renal failure with undefined renal desease, even if the typical clinical presentation of hypothyroidism is absent. Thyroid hormone assays sholud also be performed in all patients with chronic kidney disease whose kidney function is rapidly worsening.

Fiber tracking algorithms yield valuable information for neurosurgery as well as automated diagnostic approaches. However, they have not yet arrived in the daily clinical practice. In this paper we present an open source integration of the global tractography algorithm proposed by Reisert et.al.1 into the open source Medical Imaging Interaction Toolkit (MITK) developed and maintained by the Division of Medical and Biological Informatics at the German Cancer Research Center (DKFZ). The integration of this algorithm into a standardized and open development environment like MITK enriches accessibility of tractography algorithms for the science community and is an important step towards bringing neuronal tractography closer to a clinical application. The MITK diffusion imaging application, downloadable from www.mitk.org, combines all the steps necessary for a successful tractography: preprocessing, reconstruction of the images, the actual tracking, live monitoring of intermediate results, postprocessing and visualization of the final tracking results. This paper presents typical tracking results and demonstrates the steps for pre- and post-processing of the images.

2017-11-01

In nursing education, physiological concepts are typically presented within a body 'systems' framework yet learners are often challenged to apply this knowledge in the holistic and functional manner needed for effective clinical decision-making and safe patient care. A nursing faculty addressed this learning challenge by developing an advanced organizer as a conceptual and integrative learning tool to support learners in diverse learning environments and practice settings. A mixed methods research study was conducted that explored the effectiveness of the Oxygen Supply and Demand Framework as a learning tool in undergraduate nursing education. A pretest/post-test assessment and reflective journal were used to gather data. Findings indicated the Oxygen Supply and Demand Framework guided the development of pattern recognition and thinking processes and supported knowledge development, knowledge application and clinical decision-making. The Oxygen Supply and Demand Framework supports undergraduate students learning to provide safe and effective nursing care. Copyright © 2017 Elsevier Ltd. All rights reserved.

Genetic neurological channelopathies: molecular genetics and clinical phenotypes.

2016-01-01

Evidence accumulated over recent years has shown that genetic neurological channelopathies can cause many different neurological diseases. Presentations relating to the brain, spinal cord, peripheral nerve or muscle mean that channelopathies can impact on almost any area of neurological practice. Typically, neurological channelopathies are inherited in an autosomal dominant fashion and cause paroxysmal disturbances of neurological function, although the impairment of function can become fixed with time. These disorders are individually rare, but an accurate diagnosis is important as it has genetic counselling and often treatment implications. Furthermore, the study of less common ion channel mutation-related diseases has increased our understanding of pathomechanisms that is relevant to common neurological diseases such as migraine and epilepsy. Here, we review the molecular genetic and clinical features of inherited neurological channelopathies. Published by the BMJ Publishing Group Limited.

1997-01-01

Clinical trials today typically are inefficient, paper-based operations. Poor community physician awareness of available trials and difficult referral mechanisms also contribute to poor accrual. The Physicians Research Network (PRN) web was developed for more efficient trial protocol distribution and eligibility inquiries. The Medical University of South Carolina's Hollings Cancer Center trials program and two community oncology practices served as a testbed. In 581 man-hours over 18 months, 147 protocols were loaded into PRN. The trials program eliminated all protocol hardcopies except the masters, reduced photocopier use 59%, and saved 1.0 full-time equivalents (FTE), but 1.0 FTE was needed to manage PRN. There were no known security breaches, downtime, or content-related problems. Therefore, PRN is a paperless, user-preferred, reliable, secure method for distributing protocols and reducing distribution errors and delays because only a single copy of each protocol is maintained. Furthermore, PRN is being extended to serve other aspects of trial operations. PMID:8988471

Bayesian predictive power: choice of prior and some recommendations for its use as probability of success in drug development.

Bayesian predictive power, the expectation of the power function with respect to a prior distribution for the true underlying effect size, is routinely used in drug development to quantify the probability of success of a clinical trial. Choosing the prior is crucial for the properties and interpretability of Bayesian predictive power. We review recommendations on the choice of prior for Bayesian predictive power and explore its features as a function of the prior. The density of power values induced by a given prior is derived analytically and its shape characterized. We find that for a typical clinical trial scenario, this density has a u-shape very similar, but not equal, to a β-distribution. Alternative priors are discussed, and practical recommendations to assess the sensitivity of Bayesian predictive power to its input parameters are provided. Copyright © 2016 John Wiley & Sons, Ltd.

Beyond Information Retrieval—Medical Question Answering

Physicians have many questions when caring for patients, and frequently need to seek answers for their questions. Information retrieval systems (e.g., PubMed) typically return a list of documents in response to a user’s query. Frequently the number of returned documents is large and makes physicians’ information seeking “practical only ‘after hours’ and not in the clinical settings”. Question answering techniques are based on automatically analyzing thousands of electronic documents to generate short-text answers in response to clinical questions that are posed by physicians. The authors address physicians’ information needs and described the design, implementation, and evaluation of the medical question answering system (MedQA). Although our long term goal is to enable MedQA to answer all types of medical questions, currently, we currently implement MedQA to integrate information retrieval, extraction, and summarization techniques to automatically generate paragraph-level text for definitional questions (i.e., “What is X?”). MedQA can be accessed at http://www.dbmi.columbia.edu/~yuh9001/research/MedQA.html. PMID:17238385

Effective clinical decision support (CDS) is essential for addressing healthcare performance improvement imperatives, but care delivery organizations (CDO) typically struggle with CDS deployment. Ensuring safe and effective medication delivery to patients is a central focus of CDO performance improvement efforts, and this article provides an overview of best-practice strategies for applying CDS to these goals. The strategies discussed are drawn from a new guidebook, co-published and co-sponsored by more than a dozen leading organizations. Developed by scores of CDS implementers and experts, the guidebook outlines key steps and success factors for applying CDS to medication management. A central thesis is that improving outcomes with CDS interventions requires that the CDS five rights be addressed successfully. That is, the interventions must deliver the right information, to the right person, in the right format, through the right channel, at the right point in workflow. This paper provides further details about these CDS five rights, and highlights other important strategies for successful CDS programs. PMID:19894486

. Mixed methods designs: an innovative methodological approach for nursing research. The mixed method research designs (MM) combine qualitative and quantitative approaches in the research process, in a single study or series of studies. Their use can provide a wider understanding of multifaceted phenomena. This article presents a general overview of the structure and design of MM to spread this approach in the Italian nursing research community. The MM designs most commonly used in the nursing field are the convergent parallel design, the sequential explanatory design, the exploratory sequential design and the embedded design. For each method a research example is presented. The use of MM can be an added value to improve clinical practices as, through the integration of qualitative and quantitative methods, researchers can better assess complex phenomena typical of nursing.

Viscosity coefficients of microfluids—Newtonian and non-Newtonian—were explored through the rotational motion of a particle trapped by optical tweezers in a microflute. Unlike conventional methods based on viscometers, our microfluidic system employs samples of less than 30 μl to complete a measurement. Viscosity coefficients of ethanol and fetal bovine serum, as typical examples of Newtonian and non-Newtonian fluids, were obtained experimentally, and found to be in excellent agreement with theoretical predictions. Additionally, a practical application to a DNA solution with incremental ethidium bromide content was employed and the results are consistent with clinical data, indicating that our system provides a potentially important complementary tool for use in such biological and medical applications.

International guidelines for contrast-enhanced ultrasonography: ultrasound imaging in the new millennium

PubMed Central

Lorentzen, Torben

2016-01-01

The intent of this review is to discuss and comment on common clinical scenarios in which contrast-enhanced ultrasonography (CEUS) may play a decisive role and to illustrate important points with typical cases. With the advent of CEUS, the scope of indications for ultrasonography has been dramatically extended, and now includes functional imaging and tissue characterization, which in many cases enable tumor diagnosis without a biopsy. It is virtually impossible to imagine the practice of modern medicine as we know it in high-income countries without the use of imaging, and yet, an estimated two thirds of the global population may receive no such care. Ultrasound imaging with CEUS has the potential to correct this inequity. PMID:26867761

Adolescents with autism spectrum disorder often do not have access to crucial peer social activities. This study examines how typically developing adolescents evaluate decisions not to include a peer based on disability status, and the justifications they apply to these decisions. A clinical interview methodology was used to elicit judgments and justifications across four contexts. We found adolescents are more likely to judge the failure to include as acceptable in personal as compared to public contexts. Using logistic regression, we found that adolescents are more likely to provide moral justifications as to why failure to include is acceptable in a classroom as compared to home, lab group, and soccer practice contexts. Implications for intervention are also discussed.

[Purpose] This study aimed to investigate Japanese physical therapists’ attitudes of evidence-based practice and clinical practice guidelines. [Subjects and Methods] In 2014, a cross-sectional postal mail survey using a self-administered questionnaire was conducted. Of 2,982 physical therapists belonging to the Chiba Prefecture Physical Therapist Association, 1,000 were randomly selected. The questionnaire comprised 42 items pertaining to the attitudes of and behavior toward evidence-based practice and clinical practice guidelines. It was investigated to reveal the relationship between clinical practice guidelines/evidence-based practice and therapist characteristics. [Results] The response rate was 39.6%, and 384 questionnaires were available. The main results were as follows: 83.3% participants agreed to the importance of evidence-based practice, 77.1% agree to that evidence-based practice supports clinical decision of physical therapists, and about 11% agreed to have been educated about evidence-based practice. Then, 29.2% used, 54.9% agreed to the importance of, and 13.3% agreed to the utility of clinical practice guidelines. An important factor related mostly to a positive attitude, knowledge and behavior of evidence-based practice and clinical practice guidelines was participating in research activities. [Conclusion] Many of physical therapists do not use and understand the importance of clinical practice guidelines. Participating in research activities may partially contribute to improving these conditions. PMID:28265139

We aimed to assess effectiveness and tolerability of rotigotine in patients with moderate to severe idiopathic restless legs syndrome (RLS) under daily practice conditions in Germany. In this 3-month noninterventional study, effectiveness was assessed using RLS-6 (primary variables were symptom severity when falling asleep [item 2] and during the night [item 3]). Data were collected at baseline and at the end of treatment. Safety assessments included adverse events (AEs). Six hundred and eighty-four patients were treated with rotigotine and 418 (61%) completed the study. The full analysis set (FAS) comprised 564 patients (106 de novo; 458 pretreated [454 had complete rotigotine dosing data]). Mean rotigotine dose of longest duration was 2.4±1.4 mg/24 h. Rotigotine improved all RLS-6 items (mean change from baseline [item 2], -2.4±3.6; [item 3], -2.7±3.4), with the most pronounced improvement observed in daytime symptoms while at rest (item 4, -2.9±3.2). AEs were typical of dopaminergic treatment and transdermal administration. De novo patients generally started rotigotine on 1 mg/24 h (85% [90/106]) and pretreated patients on 1 (50% [227/454]) or 2 mg/24 h (40% [183/454]). Most patients who were pretreated with levodopa (57%), pramipexole (84%), or ropinirole (78%) monotherapy discontinued these medications on initiation of rotigotine. Rotigotine was effective and well-tolerated when used in routine clinical practice. Copyright © 2013 Elsevier B.V. All rights reserved.

Understanding the phenomenon of nursing student empowerment in clinical practice is important. Investigating the cognition of empowerment and identifying predictors are necessary to enhance nursing student empowerment in clinical practice. To identify empowerment predictors for Korean nursing students in clinical practice based on studies by Bradbury-Jones et al. and Spreitzer. A cross-sectional design was used for this study. This study was performed in three nursing colleges in Korea, all of which had similar baccalaureate nursing curricula. Three hundred seven junior or senior nursing students completed a survey designed to measure factors that were hypothesized to influence nursing student empowerment in clinical practice. Data were collected from November to December 2011. Study variables included self-esteem, clinical decision making, being valued as a learner, satisfaction regarding practice with a team member, perception on professor/instructor/clinical preceptor attitude, and total number of clinical practice fields. Data were analyzed using stepwise multiple regression analyses. All of the hypothesized study variables were significantly correlated to nursing student empowerment. Stepwise multiple regression analysis revealed that clinical decision making in nursing (t=7.59, p<0.001), being valued as a learner (t=6.24, p<0.001), self-esteem (t=3.62, p<0.001), and total number of clinical practice fields (t=2.06, p=0.040). The explanatory power of these predictors was 35% (F=40.71, p<0.001). Enhancing nursing student empowerment in clinical practice will be possible by using educational strategies to improve nursing student clinical decision making. Simultaneously, attitudes of nurse educators are also important to ensure that nursing students are treated as valued learners and to increase student self-esteem in clinical practice. Finally, diverse clinical practice field environments should be considered to enhance experience. Copyright © 2015 Elsevier Ltd. All rights reserved.

Accuracy of intuition in clinical decision-making among novice clinicians.

To assess the reliance on intuitive and analytical approaches during clinical decision-making among novice clinicians and whether that reliance is associated with accurate decision-making. Nurse educators and managers tend to emphasize analysis over intuition during clinical decision-making though nurses typically report some reliance on intuition in their practice. We hypothesized that under certain conditions, reliance on intuition would support accurate decision-making, even among novices. This study utilized an experimental design with clinical complication (familiar vs. novel) and decision phase (cue acquisition, diagnosis and action) as within-subjects' factors, and simulation role (observer, family, auxiliary nurse and primary nurse) as between-subjects' factor. We examined clinical decision-making accuracy among final semester pre-licensure nursing students in a simulation experience. Students recorded their reasoning about emerging clinical complications with their patient during two distinct points in the simulation; one point involved a familiar complication and the other a relatively novel complication. All data were collected during Spring 2015. Although most participants relied more heavily on analysis than on intuition, use of intuition during the familiar complication was associated with more accurate decision-making, particularly in guiding attention to relevant cues. With the novel complication, use of intuition appeared to hamper decision-making, particularly for those in an observer role. Novice clinicians should be supported by educators and nurse managers to note when their intuitions are likely to be valid. Our findings emphasize the integrated nature of intuition and analysis in clinical decision-making. © 2016 John Wiley & Sons Ltd.

Current measures of parent feeding practices are typically survey-based and assessed as static/unchanging characteristics, failing to account for fluctuations in these behaviors across time and context. The current study uses ecological momentary assessment to examine variability of, and predictors of, parent feeding practices within a low-income, racially/ethnically diverse, and immigrant sample. Children ages 5-7 years old and their parents (n = 150 dyads) from six racial/ethnic groups (n = 25 from each; Black/African American, Hispanic, Hmong, Native American, Somali, White) were recruited for this mixed-methods study through primary care clinics. Among parents who used restriction (49%) and pressure-to-eat (69%) feeding practices, these feeding practices were utilized about every other day. Contextual factors at the meal associated with parent feeding practices included: number of people at the meal, who prepared the meal, types of food served at meals (e.g., pre-prepared, homemade, fast food), meal setting (e.g., kitchen table, front room), and meal emotional atmosphere (p < 0.05). Parents tended to restrict desserts, dairy, and vegetables and pressure children to eat fruits, vegetables, meat proteins, and refined grains (p < 0.05). There were some differences by race/ethnicity across findings (p < 0.01), with Hmong parents engaging in the highest levels of pressure-to-eat feeding practices. Parent feeding practices varied across the week, indicating feeding practices are more likely to be context-specific, or state-like than trait-like. There were some meal characteristics more strongly associated with engaging in restriction and pressure-to-eat feeding practices. Given that parent feeding practices appear to be state-like, future interventions and health care providers who work with parents and children may want to address contextual factors associated with parent feeding practices to decrease restriction and pressure-to-eat parent feeding practices.

Autoimmune Subepidermal Bullous Diseases of the Skin and Mucosae: Clinical Features, Diagnosis, and Management.

PubMed

2018-02-01

Autoimmune subepidermal blistering diseases of the skin and mucosae constitute a large group of sometimes devastating diseases, encompassing bullous pemphigoid, gestational pemphigoid, mucous membrane pemphigoid, epidermolysis bullosa acquisita, and anti-p200 pemphigoid. Their clinical presentation is polymorphic. These autoimmune blistering diseases are associated with autoantibodies that target distinct components of the basement membrane zone of stratified epithelia. These autoantigens represent structural proteins important for maintenance of dermo-epidermal integrity. Bullous pemphigoid (BP) is the most common subepidermal autoimmune blistering disease of the skin and mucosae. Although the disease typically presents with a generalized blistering eruption associated with itch, atypical variants with either localized bullous lesions or "non-bullous" presentations are observed in approximately 20% of patients. A peculiar form of BP typically associated with pregnancy is pemphigoid gestationis. In anti-p200 pemphigoid, patients present with tense blisters on erythematosus or normal skin resembling BP, with a predilection for acral surfaces. These patients have antibodies targeting the 200-kDa basement membrane protein. Epidermolysis bullosa is a rare autoimmune blistering disease associated with autoantibodies against type VII collagen that can have several phenotypes including a classical form mimicking dystrophic epidermolysis bullosa, an inflammatory presentation mimicking BP, or mucous membrane pemphigoid-like lesions. Mucous membrane pemphigoid (MMP) is the term agreed upon by international consensus for an autoimmune blistering disorder, which affects one or more mucous membrane and may involve the skin. The condition involves a number of different autoantigens in the basement membrane zone. It may result in severe complications from scarring, such as blindness and strictures. Diagnosis of these diseases relies on direct immunofluorescence microscopy studies and immunoserological assays. Management of affected patients is often challenging. We will here review the clinical and immunopathological features as well as the pathophysiology of this group of organ-specific autoimmune diseases. Finally, we will discuss the diagnostic approach and the principles of management in clinical practice.

Management of Lyme Disease in European Children: a Review for Practical Purpose.

PubMed

D'Alessandro, Matteo; Loy, Anna; Castagnola, Elio

2017-08-01

Lyme disease is a tick-borne zoonosis transmitted through a bite of a tick carrying a spirochete belonging to Borrelia species. In the last 20 years, the reported incidence of Lyme disease is increased by three times in Europe. Clinically, the illness develops through a primary stage with a typical skin rash (erythema marginatum), then a secondary stage with possible neurologic or cardiac involvement. The last stage (chronic Lyme disease) is mainly represented by arthritis or late neurological complications but nowadays is rarely seen due to precocious antibiotic use. The diagnosis of Lyme disease is essentially based on history in agreement with tick exposure (living/recent traveling in endemic area or tick bite) and clinical findings compatible with the disease. At present, no laboratory diagnostic tool available can neither establish nor exclude the diagnosis of Lyme disease. The management of Lyme disease should comprise a prophylactic administration of antibiotic in selected population (patients exposed to a tick bite in endemic regions) in which the typical signs of Lyme disease are not yet appeared; conversely, patients with current signs of Lyme disease should undergo a standard therapeutic course. First-line therapy should be oral tetracycline or oral penicillin/cephalosporin (in pediatric populations, beta-lactamic drugs are preferred).

Evidence-based ethics? On evidence-based practice and the "empirical turn" from normative bioethics

PubMed Central

Goldenberg, Maya J

2005-01-01

Background The increase in empirical methods of research in bioethics over the last two decades is typically perceived as a welcomed broadening of the discipline, with increased integration of social and life scientists into the field and ethics consultants into the clinical setting, however it also represents a loss of confidence in the typical normative and analytic methods of bioethics. Discussion The recent incipiency of "Evidence-Based Ethics" attests to this phenomenon and should be rejected as a solution to the current ambivalence toward the normative resolution of moral problems in a pluralistic society. While "evidence-based" is typically read in medicine and other life and social sciences as the empirically-adequate standard of reasonable practice and a means for increasing certainty, I propose that the evidence-based movement in fact gains consensus by displacing normative discourse with aggregate or statistically-derived empirical evidence as the "bottom line". Therefore, along with wavering on the fact/value distinction, evidence-based ethics threatens bioethics' normative mandate. The appeal of the evidence-based approach is that it offers a means of negotiating the demands of moral pluralism. Rather than appealing to explicit values that are likely not shared by all, "the evidence" is proposed to adjudicate between competing claims. Quantified measures are notably more "neutral" and democratic than liberal markers like "species normal functioning". Yet the positivist notion that claims stand or fall in light of the evidence is untenable; furthermore, the legacy of positivism entails the quieting of empirically non-verifiable (or at least non-falsifiable) considerations like moral claims and judgments. As a result, evidence-based ethics proposes to operate with the implicit normativity that accompanies the production and presentation of all biomedical and scientific facts unchecked. Summary The "empirical turn" in bioethics signals a need for reconsideration of the methods used for moral evaluation and resolution, however the options should not include obscuring normative content by seemingly neutral technical measure.

At present, several clinical practice guidelines for the treatment of osteoarthritis have been developed by institutes or societies. The ultimate purpose of developing clinical practice guidelines is to formulate the process in the treatment of osteoarthritis effectively. However, the methodologies used in developing clinical practice guidelines may place an influence on the transformation and application of that in treating osteoarthritis. The present study summarized the methodological features of individual clinical practice guideline and presented the tools for quality evaluation of clinical practice guideline. The limitations of current osteoarthritis guidelines of China are also indicated. The review article might help relevant institutions improve the quality in developing guide and clinical transformation.

Agreement Analysis: What He Said, She Said Versus You Said.

Vetter, Thomas R; Schober, Patrick

2018-06-01

Correlation and agreement are 2 concepts that are widely applied in the medical literature and clinical practice to assess for the presence and strength of an association. However, because correlation and agreement are conceptually distinct, they require the use of different statistics. Agreement is a concept that is closely related to but fundamentally different from and often confused with correlation. The idea of agreement refers to the notion of reproducibility of clinical evaluations or biomedical measurements. The intraclass correlation coefficient is a commonly applied measure of agreement for continuous data. The intraclass correlation coefficient can be validly applied specifically to assess intrarater reliability and interrater reliability. As its name implies, the Lin concordance correlation coefficient is another measure of agreement or concordance. In undertaking a comparison of a new measurement technique with an established one, it is necessary to determine whether they agree sufficiently for the new to replace the old. Bland and Altman demonstrated that using a correlation coefficient is not appropriate for assessing the interchangeability of 2 such measurement methods. They in turn described an alternative approach, the since widely applied graphical Bland-Altman Plot, which is based on a simple estimation of the mean and standard deviation of differences between measurements by the 2 methods. In reading a medical journal article that includes the interpretation of diagnostic tests and application of diagnostic criteria, attention is conventionally focused on aspects like sensitivity, specificity, predictive values, and likelihood ratios. However, if the clinicians who interpret the test cannot agree on its interpretation and resulting typically dichotomous or binary diagnosis, the test results will be of little practical use. Such agreement between observers (interobserver agreement) about a dichotomous or binary variable is often reported as the kappa statistic. Assessing the interrater agreement between observers, in the case of ordinal variables and data, also has important biomedical applicability. Typically, this situation calls for use of the Cohen weighted kappa. Questionnaires, psychometric scales, and diagnostic tests are widespread and increasingly used by not only researchers but also clinicians in their daily practice. It is essential that these questionnaires, scales, and diagnostic tests have a high degree of agreement between observers. It is therefore vital that biomedical researchers and clinicians apply the appropriate statistical measures of agreement to assess the reproducibility and quality of these measurement instruments and decision-making processes.

There is much interest in virtual consultations using video technology. Randomized controlled trials have shown video consultations to be acceptable, safe, and effective in selected conditions and circumstances. However, this model has rarely been mainstreamed and sustained in real-world settings. The study sought to (1) define good practice and inform implementation of video outpatient consultations and (2) generate transferable knowledge about challenges to scaling up and routinizing this service model. A multilevel, mixed-method study of Skype video consultations (micro level) was embedded in an organizational case study (meso level), taking account of national context and wider influences (macro level). The study followed the introduction of video outpatient consultations in three clinical services (diabetes, diabetes antenatal, and cancer surgery) in a National Health Service trust (covering three hospitals) in London, United Kingdom. Data sources included 36 national-level stakeholders (exploratory and semistructured interviews), longitudinal organizational ethnography (300 hours of observations; 24 staff interviews), 30 videotaped remote consultations, 17 audiotaped face-to-face consultations, and national and local documents. Qualitative data, analyzed using sociotechnical change theories, addressed staff and patient experience and organizational and system drivers. Quantitative data, analyzed via descriptive statistics, included uptake of video consultations by staff and patients and microcategorization of different kinds of talk (using the Roter interaction analysis system). When clinical, technical, and practical preconditions were met, video consultations appeared safe and were popular with some patients and staff. Compared with face-to-face consultations for similar conditions, video consultations were very slightly shorter, patients did slightly more talking, and both parties sometimes needed to make explicit things that typically remained implicit in a traditional encounter. Video consultations appeared to work better when the clinician and patient already knew and trusted each other. Some clinicians used Skype adaptively to respond to patient requests for ad hoc encounters in a way that appeared to strengthen supported self-management. The reality of establishing video outpatient services in a busy and financially stretched acute hospital setting proved more complex and time-consuming than originally anticipated. By the end of this study, between 2% and 22% of consultations were being undertaken remotely by participating clinicians. In the remainder, clinicians chose not to participate, or video consultations were considered impractical, technically unachievable, or clinically inadvisable. Technical challenges were typically minor but potentially prohibitive. Video outpatient consultations appear safe, effective, and convenient for patients in situations where participating clinicians judge them clinically appropriate, but such situations are a fraction of the overall clinic workload. As with other technological innovations, some clinicians will adopt readily, whereas others will need incentives and support. There are complex challenges to embedding video consultation services within routine practice in organizations that are hesitant to change, especially in times of austerity. ©Trisha Greenhalgh, Sara Shaw, Joseph Wherton, Shanti Vijayaraghavan, Joanne Morris, Satya Bhattacharya, Philippa Hanson, Desirée Campbell-Richards, Seendy Ramoutar, Anna Collard, Isabel Hodkinson.

The American College of Physicians (ACP) established its evidence-based clinical practice guidelines program in 1981. The ACP's Guidelines Committee and the staff of the Clinical Programs and Quality of Care Department develop the clinical recommendations. The ACP develops 2 different types of clinical recommendations: clinical practice guidelines and clinical guidance statements. The ACP clinical practice guidelines and guidance statements follow a multistep development process that includes a systematic review of the evidence, deliberation of the evidence by the committee, summary recommendations, and evidence and recommendation grading. All ACP clinical practice guidelines and clinical guidance statements, if not updated, are considered automatically withdrawn or invalid 5 years after publication or once an update has been issued.

An Opportunity to Bridge the Gap Between Clinical Research and Clinical Practice: Implications for Clinical Training

2013-01-01

Clinical researchers and clinical practitioners share a goal of increasing the integration of research and clinical practice, which is reflected in an evidence-based practice (EBP) approach to psychology. The EBP framework involves the integration of research findings with clinical expertise and client characteristics, values, and preferences, and consequently provides an important foundation for conducting clinically relevant research, as well as empirically based and clinically sensitive practice. Given the critical role that early training can play in the integration of science and practice and in promoting the future of the field, the present article addresses predoctoral training programs as a context for adopting an EBP approach to clinical work. We address training in the three components of EBP and provide suggestions for curriculum development and practicum training that we hope will contribute to bridging the gap between research and practice.

Ultrasound (US) is the most commonly used liver imaging modality worldwide. It plays an important role in follow-up of cancer patients with liver metastases. We present an interactive segmentation approach for liver tumors in US acquisitions. Due to the low image quality and the low contrast between the tumors and the surrounding tissue in US images, the segmentation is very challenging. Thus, the clinical practice still relies on manual measurement and outlining of the tumors in the US images. We target this problem by applying an interactive segmentation algorithm to the US data, allowing the user to get real-time feedback of the segmentation results. The algorithm has been developed and tested hand-in-hand by physicians and computer scientists to make sure a future practical usage in a clinical setting is feasible. To cover typical acquisitions from the clinical routine, the approach has been evaluated with dozens of datasets where the tumors are hyperechoic (brighter), hypoechoic (darker) or isoechoic (similar) in comparison to the surrounding liver tissue. Due to the interactive real-time behavior of the approach, it was possible even in difficult cases to find satisfying segmentations of the tumors within seconds and without parameter settings, and the average tumor deviation was only 1.4mm compared with manual measurements. However, the long term goal is to ease the volumetric acquisition of liver tumors in order to evaluate for treatment response. Additional aim is the registration of intraoperative US images via the interactive segmentations to the patient's pre-interventional CT acquisitions.

Background Cardiovascular disease remains the major contributor to morbidity and mortality. In routine care for patients with an elevated cardiovascular risk or with symptomatic cardiovascular disease information is mostly collected in an unstructured manner, making the data of limited use for structural feedback, quality control, learning and scientific research. Objective The Utrecht Cardiovascular Cohort (UCC) initiative aims to create an infrastructure for uniform registration of cardiovascular information in routine clinical practice for patients referred for cardiovascular care at the University Medical Center Utrecht, the Netherlands. This infrastructure will promote optimal care according to guidelines, continuous quality control in a learning healthcare system and creation of a research database. Methods The UCC comprises three parts. UCC-1 comprises enrolment of all eligible cardiovascular patients in whom the same information will be collected, based on the Dutch cardiovascular management guideline. A sample of UCC-1 will be invited for UCC-2. UCC-2 involves an enrichment through extensive clinical measurements with emphasis on heart failure, cerebral ischaemia, arterial aneurysms, diabetes mellitus and elevated blood pressure. UCC-3 comprises on-top studies, with in-depth measurements in smaller groups of participants typically based on dedicated project grants. All participants are followed up for morbidity and mortality through linkage with national registries. Conclusion In a multidisciplinary effort with physicians, patients and researchers the UCC sets a benchmark for a learning cardiovascular healthcare system. UCC offers an invaluable resource for future high quality care as well as for first-class research for investigators.

Empagliflozin/linagliptin single-pill combination therapy for patients with type 2 diabetes mellitus.

PubMed

2017-04-01

Type 2 diabetes mellitus (T2DM) is typically progressive, with sequential addition of therapies often needed to address increasing hyperglycemia over the disease course. Using treatments in combination may be preferred to sequential addition, as a means of providing a more rapid clinical response and potentially avoiding clinical inertia. In such cases, a single-pill combination can help to reduce pill burden. Although various single-pill combinations of oral glucose-lowering agents are available, empagliflozin/linagliptin was the first approved combination of a sodium glucose co-transporter 2 (SGLT2) inhibitor with a dipeptidyl peptidase 4 (DPP-4) inhibitor in the United States. Areas covered: Two publications of the clinical trial investigating the efficacy and safety of single-pill combinations of empagliflozin/linagliptin in treatment-naive or metformin-treated patients with T2DM (NCT01422876) are reviewed, and their potential impact on clinical practice is discussed. Expert opinion: The study discussed provides evidence for the efficacy and safety of empagliflozin/linagliptin single pills. Addition of an empagliflozin/linagliptin single pill may be considered in patients with inadequate glycemic control on metformin, or as an alternative to first-line treatment with empagliflozin or linagliptin when metformin is not suitable, particularly in patients with very poor glycemic control, or those who need to achieve target more quickly.

Benign hepatocellular nodules of healthy liver: focal nodular hyperplasia and hepatocellular adenoma

PubMed Central

Roncalli, Massimo; Sciarra, Amedeo; Tommaso, Luca Di

2016-01-01

Owing to the progress of imaging techniques, benign hepatocellular nodules are increasingly discovered in the clinical practice. This group of lesions mostly arises in the context of a putatively normal healthy liver and includes either pseudotumoral and tumoral nodules. Focal nodular hyperplasia and hepatocellular adenoma are prototypical examples of these two categories of nodules. In this review we aim to report the main pathological criteria of differential diagnosis between focal nodular hyperplasia and hepatocellular adenoma, which mainly rests upon morphological and phenotypical features. We also emphasize that for a correct diagnosis the clinical context such as sex, age, assumption of oral contraceptives, associated metabolic or vascular disturbances is of paramount importance. While focal nodular hyperplasia is a single entity epidemiologically more frequent than adenoma, the latter is representative of a more heterogeneous group which has been recently and extensively characterized from a clinical, morphological, phenotypical and molecular profile. The use of the liver biopsy in addition to imaging and the clinical context are important diagnostic tools of these lesions. In this review we will survey their systematic pathobiology and propose a diagnostic algorithm helpful to increase the diagnostic accuracy of not dedicated liver pathologists. The differential diagnosis between so-called typical and atypical adenoma and well differentiated hepatocellular carcinoma will also be discussed. PMID:27189732

An experimental clinical evaluation of EIT imaging with ℓ1 data and image norms.

Electrical impedance tomography (EIT) produces an image of internal conductivity distributions in a body from current injection and electrical measurements at surface electrodes. Typically, image reconstruction is formulated using regularized schemes in which ℓ2-norms are used for both data misfit and image prior terms. Such a formulation is computationally convenient, but favours smooth conductivity solutions and is sensitive to outliers. Recent studies highlighted the potential of ℓ1-norm and provided the mathematical basis to improve image quality and robustness of the images to data outliers. In this paper, we (i) extended a primal-dual interior point method (PDIPM) algorithm to 2.5D EIT image reconstruction to solve ℓ1 and mixed ℓ1/ℓ2 formulations efficiently, (ii) evaluated the formulation on clinical and experimental data, and (iii) developed a practical strategy to select hyperparameters using the L-curve which requires minimum user-dependence. The PDIPM algorithm was evaluated using clinical and experimental scenarios on human lung and dog breathing with known electrode errors, which requires a rigorous regularization and causes the failure of reconstruction with an ℓ2-norm solution. The results showed that an ℓ1 solution is not only more robust to unavoidable measurement errors in a clinical setting, but it also provides high contrast resolution on organ boundaries.

Involvement of the central nervous system (CNS) by Histoplasma capsulatum in AIDS is uncommon and not easily recognized. CNS histoplasmosis cases from our institution were identified by a retrospective chart review from 2004-2014. A thorough literature search was performed for additional cases and their characteristics were compared. Clinical findings, treatment and outcomes are discussed. A total of 5 cases from our institution were identified. They had a clinical presentation that included classic signs of meningitis, often with evidence of disseminated involvement, and was typically severe with important neurological impairment. These cases were treated with antifungal agents, including a lipid amphotericin B formulation and azole drugs, but eventually 3 experienced nonresolution of their disease likely because of lack of adherence to therapy and died from their infection. The clinical presentation, treatment and outcome of these cases did not significantly differ from cases found in the review of the literature. Clinicians practicing in endemic areas should be aware of this rare but serious form of histoplasmosis. The recognition of 5 cases of CNS histoplasmosis in AIDS patients from a single institution suggests that histoplasmosis should be included in the differential diagnosis of the CNS complications of AIDS.

2017-04-01

To investigate the formation of one kind of typical inter-dendritic crack around triple point region in continuous casting(CC) slab during the operation of soft reduction, fully coupled 3D thermo-mechanical finite element models was developed, also plant trials were carried out in a domestic continuous casting machine. Three possible types of soft reduction amount distribution (SRAD) in the soft reduction region were analyzed. The relationship between the typical inter-dendritic cracks and soft reduction conditions is presented and demonstrated in production practice. Considering the critical strain of internal crack formation, a critical tolerance for the soft reduction amount distribution and related casing parameters have been proposed for better contribution of soft reduction to the internal quality of slabs. The typical inter-dendritic crack around the triple point region had been eliminated effectively through the application of proposed suggestions for continuous casting of X70 pipeline steel in industrial practice.

Celiac disease presents with a spectrum of clinical disorders. The variety of clinical presentations largely depends on age and extraintestinal findings. This study aimed to determine typical and atypical cases according to presenting symptoms and to evaluate their biochemical and pathological parameters. Eighty-seven patients with celiac disease in our unit between 2000 and 2007 were reviewed. Their diagnosis was made by serological and histological examination. The patients were divided into two groups according to their typical or atypical symptoms. The mean age of the patients at diagnosis was 8.2 years (range, 1-18 years), but patients presenting with typical symptoms were younger than those presenting with atypical symptoms. The patients in the two groups did not differ significantly in sex, weight and height Z scores except age. Diarrhea (96.3%), abdominal distention (65.4%) and failure to thrive (60%) were the most common clinical presentations in the typical group, and short stature (62.5%) and anemia (31.2%) were the most common in the atypical group. Total/subtotal villous atrophy was significantly higher in the typical group than in the atypical group. Many children with celiac disease show an atypical form. The understanding of presentations of celiac disease may prevent delayed diagnosis. Celiac disease should be specially investigated in patients with recurrent iron deficiency anemia, short stature and autoimmune disorders.

Objective To examine the perceived effect of teaching clinical skills and associated teacher training programmes on general practitioners' morale and clinical practice. Design Qualitative semistructured interview study. Setting General practices throughout north London. Subjects 30 general practitioners who taught clinical skills were asked about the effect of teaching and teacher training on their morale, confidence in clinical and teaching skills, and clinical practice. Results The main theme was a positive effect on morale. Within teacher training this was attributed to developing peer and professional support; improved teaching skills; and revision of clinical knowledge and skills. Within teaching this was attributed to a broadening of horizons; contact with enthusiastic students; increased time with patients; improved clinical practice; improved teaching skills; and an improved image of the practice. Problems with teaching were due to external factors such as lack of time and space and anxieties about adequacy of clinical cover while teaching. Conclusions Teaching clinical skills can have a positive effect on the morale of general practitioner teachers as a result of contact with students and peers, as long as logistic and funding issues are adequately dealt with. Key messagesThe increase in community based teaching of clinical skills requires an increase in the number of general practitioner teachersLittle evidence is available about the effect of teaching of clinical skills and teacher training on general practitioner teachers and practicesGeneral practitioner teachers reported an increase in morale, improvements in clinical skills, and changes in clinical practice and in practice infrastructure as a result of teaching and trainingGeneral practitioner teachers reported problems because of pressure on time, lack of space, problems recruiting patients, and unsupportive practice partnersPositive effects on morale and clinical practice may be important for sustainable teaching and continuing medical education PMID:10541508

Teaching basic science to optimize transfer.

PubMed

Norman, Geoff

2009-09-01

Basic science teachers share the concern that much of what they teach is soon forgotten. Although some evidence suggests that relatively little basic science is forgotten, it may not appear so, as students commonly have difficulty using these concepts to solve or explain clinical problems: This phenomenon, using a concept learned in one context to solve a problem in a different context, is known to cognitive psychologists as transfer. The psychology literature shows that transfer is difficult; typically, even though students may know a concept, fewer than 30% will be able to use it to solve new problems. However a number of strategies to improve transfer can be adopted at the time of initial teaching of the concept, in the use of exemplars to illustrate the concept, and in practice with additional problems. In this article, we review the literature in psychology to identify practical strategies to improve transfer. Critical review of psychology literature to identify factors that enhance or impede transfer. There are a number of strategies available to teachers to facilitate transfer. These include active problem-solving at the time of initial learning, imbedding the concept in a problem context, using everyday analogies, and critically, practice with multiple dissimilar problems. Further, mixed practice, where problems illustrating different concepts are mixed together, and distributed practice, spread out over time, can result in significant and large gains. Transfer is difficult, but specific teaching strategies can enhance this skill by factors of two or three.

Conceptualizing clinical nurse leader practice: an interpretive synthesis.

PubMed

Bender, Miriam

2016-01-01

The Institute of Medicine's Future of Nursing report identifies the clinical nurse leader as an innovative new role for meeting higher health-care quality standards. However, specific clinical nurse leader practices influencing documented quality outcomes remain unclear. Lack of practice clarity limits the ability to articulate, implement and measure clinical nurse leader-specific practice and quality outcomes. Interpretive synthesis design and grounded theory analysis were used to develop a theoretical understanding of clinical nurse leader practice that can facilitate systematic and replicable implementation across health-care settings. The core phenomenon of clinical nurse leader practice is continuous clinical leadership, which involves four fundamental activities: facilitating effective ongoing communication; strengthening intra and interprofessional relationships; building and sustaining teams; and supporting staff engagement. Clinical nurse leaders continuously communicate and develop relationships within and across professions to promote and sustain information exchange, engagement, teamwork and effective care processes at the microsystem level. Clinical nurse leader-integrated care delivery systems highlight the benefits of nurse-led models of care for transforming health-care quality. Managers can use this study's findings to frame an implementation strategy that addresses theoretical domains of clinical nurse leader practice to help ensure practice success. © 2015 John Wiley & Sons Ltd.

What Ethical Issues Really Arise in Practice at an Academic Medical Center? A Quantitative and Qualitative Analysis of Clinical Ethics Consultations from 2008 to 2013.

2016-09-01

As the field of clinical ethics consultation sets standards and moves forward with the Quality Attestation process, questions should be raised about what ethical issues really do arise in practice. There is limited data on the type and number of ethics consultations conducted across different settings. At Loyola University Medical Center, we conducted a retrospective review of our ethics consultations from 2008 through 2013. One hundred fifty-six cases met the eligibility criteria. We analyzed demographic data on these patients and conducted a content analysis of the ethics consultation write-ups coding both the frequency of ethical issues and most significant, or key, ethical issue per case. Patients for whom ethics consultation was requested were typically male (55.8 %), white (57.1 %), between 50 and 69 years old (38.5 %), of non-Hispanic origin (85.9 %), and of Roman Catholic faith (43.6 %). Nearly half (47.4 %) were in the intensive care unit and 44.2 % died in the hospital. The most frequent broad ethical categories were decision-making (93.6 %), goals of care/treatment (80.8 %), and end-of-life (73.1 %). More specifically, capacity (57.1 %), patient's wishes/autonomy (54.5 %), and surrogate decision maker (51.3 %) were the most frequent particular ethical issues. The most common key ethical issues were withdrawing/withholding treatment (12.8 %), patient wishes/autonomy (12.2 %), and capacity (11.5 %). Our findings provide additional data to inform the training of clinical ethics consultants regarding the ethical issues that arise in practice. A wider research agenda should be formed to collect and compare data across institutions to improve education and training in our field.

2017-03-07

Interest in nephrology has been declining in recent years. Long work hours and a poor work/life balance may be partially responsible, and may also affect a fellowship's educational mission. We surveyed nephrology program directors using a web-based survey in order to define current clinical and educational practice patterns and identify areas for improvement. Our survey explored fellowship program demographics, fellows' workload, call structure, and education. Program directors were asked to estimate the average and maximum number of patients on each of their inpatient services, the number of patients seen by fellows in clinic, and to provide details regarding their overnight and weekend call. In addition, we asked about number of and composition of didactic conferences. Sixty-eight out of 148 program directors responded to the survey (46%). The average number of fellows per program was approximately seven. The busiest inpatient services had a mean of 21.5±5.9 patients on average and 33.8±10.7 at their maximum. The second busiest services had an average and maximum of 15.6±6.0 and 24.5±10.8 patients, respectively. Transplant-only services had fewer patients than other service compositions. A minority of services (14.5%) employed physician extenders. Fellows most commonly see patients during a single weekly continuity clinic, with a typical fellow-to-faculty ratio of 2:1. The majority of programs do not alter outpatient responsibilities during inpatient service time. Most programs (approximately 75%) divided overnight and weekend call responsibilities equally between first year and more senior fellows. Educational practices varied widely between programs. Our survey underscores the large variety in workload, practice patterns, and didactics at different institutions and provides a framework to help improve the service/education balance in nephrology fellowships.

2017-01-01

Purpose Guidelines generally do not recommend oral antimicrobials for prophylaxis against chemotherapy-related infections in patients with solid tumors. Evidence on antimicrobial prophylaxis use, and associated chemotherapy-related infection risk, in US clinical practice is limited. Methods A retrospective cohort design and data from two US private healthcare claims repositories (2008-2011) were employed. Study population included adults who received myelosuppressive chemotherapy for non-metastatic cancer of the breast, colon/rectum, or lung, or for non-Hodgkin's lymphoma. For each subject, the first chemotherapy course was characterized, and within the first course, each chemotherapy cycle and chemotherapy-related infection episode was identified. Use of prophylaxis with oral antimicrobials and colony-stimulating factors in each cycle also was identified. Results A total of 7116 (22% of all) non-metastatic breast cancer, 1833 (15%) non-metastatic colorectal cancer, 1999 (15%) non-metastatic lung cancer, and 1949 (21%) non-Hodgkin's lymphoma patients received antimicrobial prophylaxis in ≥1 cycle. Mean number of antimicrobial prophylaxis cycles during the course among these patients was typically <2, with little difference across cancers and chemotherapy regimens. Fluoroquinolones were the most commonly received class of antimicrobials, accounting for 20%-50% all antimicrobials administered. Among subjects who received first-cycle antimicrobial prophylaxis, chemotherapy-related infection risk in that cycle ranged from 3% to 6% across cancer types. Among patients who received first-cycle antimicrobial prophylaxis and developed chemotherapy-related infections, 38%-67% required inpatient care. Chemotherapy-related infection risk in subsequent cycles with antimicrobial prophylaxis was comparable. Conclusion The results of this study suggest that use of antimicrobial prophylaxis during myelosuppressive chemotherapy is far from uncommon in clinical practice. The results also suggest that an important minority of cancer chemotherapy patients receiving antimicrobial prophylaxis still develop serious infection requiring hospitalization.

Clinical pharmacists have a challenging task when answering patients' question about whether they can take specific drugs with grapefruit juice (GFJ) without risk of drug interaction. To identify the most practicable method for predicting clinically relevant changes in plasma concentrations of orally administered drugs caused by the ingestion of GFJ, we compared the predictive performance of three methods using data obtained from the literature. We undertook a systematic search of drug interactions associated with GFJ using MEDLINE and the Metabolism & Transport Drug Interaction Database (DIDB version 4.0). We considered an elevation of the area under the plasma concentration-time curve (AUC) of 2 or greater relative to the control value [AUC ratio (AUCR) ≥ 2.0] as a clinically significant interaction. The data from 74 drugs (194 data sets) were analysed. When the reported information of CYP3A involvement in the metabolism of a drug of interest was adopted as a predictive criterion for GFJ-drug interaction, the performance assessed by positive predictive value (PPV) was low (0.26), but that assessed by negative predictive value (NPV) and sensitivity was high (1.00 for both). When the reported oral bioavailability of ≤ 0.1 was used as a criterion, the PPV improved to 0.50 with an acceptable NPV of 0.81, but sensitivity was reduced to 0.21. When the reported AUCR was ≥ 10 after co-administration of a typical CYP3A inhibitor, the corresponding values were 0.64, 0.79 and 0.19, respectively. We consider that an oral bioavailability of ≤ 0.1 or an AUCR of ≥ 10 caused by a CYP3A inhibitor of a drug of interest may be a practical prediction criterion for avoiding significant interactions with GFJ. Information about the involvement of CYP3A in their metabolism should also be taken into account for drugs with narrow therapeutic ranges. © 2014 John Wiley & Sons Ltd.

(18)F-labeled positron emission tomographic radiopharmaceuticals in oncology: an overview of radiochemistry and mechanisms of tumor localization.

PubMed

2007-11-01

Molecular imaging is the visualization, characterization, and measurement of biological processes at the molecular and cellular levels in a living system. At present, positron emission tomography/computed tomography (PET/CT) is one the most rapidly growing areas of medical imaging, with many applications in the clinical management of patients with cancer. Although [(18)F]fluorodeoxyglucose (FDG)-PET/CT imaging provides high specificity and sensitivity in several kinds of cancer and has many applications, it is important to recognize that FDG is not a "specific" radiotracer for imaging malignant disease. Highly "tumor-specific" and "tumor cell signal-specific" PET radiopharmaceuticals are essential to meet the growing demand of radioisotope-based molecular imaging technology. In the last 15 years, many alternative PET tracers have been proposed and evaluated in preclinical and clinical studies to characterize the tumor biology more appropriately. The potential clinical utility of several (18)F-labeled radiotracers (eg, fluoride, FDOPA, FLT, FMISO, FES, and FCH) is being reviewed by several investigators in this issue. An overview of design and development of (18)F-labeled PET radiopharmaceuticals, radiochemistry, and mechanism(s) of tumor cell uptake and localization of radiotracers are presented here. The approval of clinical indications for FDG-PET in the year 2000 by the Food and Drug Administration, based on a review of literature, was a major breakthrough to the rapid incorporation of PET into nuclear medicine practice, particularly in oncology. Approval of a radiopharmaceutical typically involves submission of a "New Drug Application" by a manufacturer or a company clearly documenting 2 major aspects of the drug: (1) manufacturing of PET drug using current good manufacturing practices and (2) the safety and effectiveness of a drug with specific indications. The potential routine clinical utility of (18)F-labeled PET radiopharmaceuticals depends also on regulatory compliance in addition to documentation of potential safety and efficacy by various investigators.

To investigate the effect of the different eligibility criteria used by phase III clinical studies in heart failure with preserved ejection fraction (HFpEF) on patient selection, phenotype, and survival. We applied the key eligibility criteria of 7 phase III HFpEF studies (Digitalis Investigation Group Ancillary, Candesartan in Patients With Chronic Heart Failure and Preserved Left-Ventricular Ejection Fraction, Perindopril in Elderly People With Chronic Heart Failure, Irbesartan in Heart Failure With Preserved Systolic Function, Japanese Diastolic Heart Failure, Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist, and Efficacy and Safety of LCZ696 Compared to Valsartan, on Morbidity and Mortality in Heart Failure Patients With Preserved Ejection Fraction [PARAGON-HF; ongoing]) to a typical and well-characterized HFpEF population (n = 557) seen in modern European cardiological practice. Follow-up was available for a minimum of 24 months in each patient. Increasing the number of study eligibility criteria identifies a progressively smaller group of patients from real-life practice suitable for recruitment into clinical trials; using the J-DHF criteria, 81% of our clinic patients would have been eligible, whereas the PARAGON-HF criteria significantly reduced this proportion to 32%. The patients identified from our clinical population had similar mortality rates using the different criteria, which were consistently higher than those reported in the actual clinic trials. Trial eligibility criteria have become stricter with time, which reduces the number of eligible patients, affecting both generalizability of any findings and feasibility of completing an adequately powered trial. We could not find evidence that the additional criteria used in more recent randomized trials in HFpEF have identified patients at higher risk of all-cause mortality. Copyright © 2017 Elsevier Inc.

Measuring forgetting: a critical review of accelerated long-term forgetting studies.

PubMed

Elliott, Gemma; Isaac, Claire L; Muhlert, Nils

2014-05-01

Accelerated long-term forgetting (ALF) refers to abnormal forgetting over hours to weeks despite normal acquisition or initial consolidation. Since standardised assessments of memory typically only test at delays of up to 40-minutes, ALF may go undetected in clinical practice. The memory difficulties associated with ALF can however cause considerable distress to patients. It is important therefore that clinicians are aware that ALF may represent a distinct phenomenon that will require additional and careful assessment to aid patients' understanding of the condition and assist in developing strategies to address its effects. At the same time, ALF may also provide insight into long-term memory processes. Studies of ALF in patients with epilepsy have so far demonstrated mixed results, which may reflect differences in methodology. This review explores the methodological issues that can affect forgetting, such as the effects of age, general cognitive function, test sensitivity and initial learning. It then evaluates the extent to which existing studies have considered these key issues. We outline the points to consider when designing ALF studies that can be used to help improve their validity. These issues can also help to explain some of the mixed findings in studies of ALF and inform the design of standardised tests for assessing ALF in clinical practice. Copyright © 2014 The Authors.

2006-03-01

We present a fully-automated and robust microarray image analysis system for handling multi-resolution images (down to 3-micron with sizes up to 80 MBs per channel). The system is developed to provide rapid and accurate data extraction for our recently developed microarray analysis and quality control tool (SNP Chart). Currently available commercial microarray image analysis applications are inefficient, due to the considerable user interaction typically required. Four-channel DNA microarray technology is a robust and accurate tool for determining genotypes of multiple genetic markers in individuals. It plays an important role in the state of the art trend where traditional medical treatments are to be replaced by personalized genetic medicine, i.e. individualized therapy based on the patient's genetic heritage. However, fast, robust, and precise image processing tools are required for the prospective practical use of microarray-based genetic testing for predicting disease susceptibilities and drug effects in clinical practice, which require a turn-around timeline compatible with clinical decision-making. In this paper we have developed a fully-automated image analysis platform for the rapid investigation of hundreds of genetic variations across multiple genes. Validation tests indicate very high accuracy levels for genotyping results. Our method achieves a significant reduction in analysis time, from several hours to just a few minutes, and is completely automated requiring no manual interaction or guidance.

Primer on clinical acid-base problem solving.

PubMed

Whittier, William L; Rutecki, Gregory W

2004-03-01

Acid-base problem solving has been an integral part of medical practice in recent generations. Diseases discovered in the last 30-plus years, for example, Bartter syndrome and Gitelman syndrome, D-lactic acidosis, and bulimia nervosa, can be diagnosed according to characteristic acid-base findings. Accuracy in acid-base problem solving is a direct result of a reproducible, systematic approach to arterial pH, partial pressure of carbon dioxide, bicarbonate concentration, and electrolytes. The 'Rules of Five' is one tool that enables clinicians to determine the cause of simple and complex disorders, even triple acid-base disturbances, with consistency. In addition, other electrolyte abnormalities that accompany acid-base disorders, such as hypokalemia, can be incorporated into algorithms that complement the Rules and contribute to efficient problem solving in a wide variety of diseases. Recently urine electrolytes have also assisted clinicians in further characterizing select disturbances. Acid-base patterns, in many ways, can serve as a 'common diagnostic pathway' shared by all subspecialties in medicine. From infectious disease (eg, lactic acidemia with highly active antiviral therapy therapy) through endocrinology (eg, Conn's syndrome, high urine chloride alkalemia) to the interface between primary care and psychiatry (eg, bulimia nervosa with multiple potential acid-base disturbances), acid-base problem solving is the key to unlocking otherwise unrelated diagnoses. Inasmuch as the Rules are clinical tools, they are applied throughout this monograph to diverse pathologic conditions typical in contemporary practice.

To establish the prevalence of patients with advance directives in a family practice, and to describe patients' perspectives on a family doctor's role in initiating discussions about advance directives. A self-administered patient questionnaire. A busy urban family medicine teaching clinic in Hamilton, Ont. A convenience sample of adult patients attending the clinic over the course of a typical business week. The prevalence of advance directives in the patient population was determined, and the patients' expectations regarding the role of their family doctors were elucidated. The survey population consisted of 800 participants (a response rate of 72.5%) well distributed across age groups; 19.7% had written advance directives and 43.8% had previously discussed the topic of advance directives, but only 4.3% of these discussions had occurred with family doctors. In 5.7% of cases, a family physician had raised the issue; 72.3% of respondents believed patients should initiate the discussion. Patients who considered advance directives extremely important were significantly more likely to want their family doctors to start the conversation (odds ratio 3.98; P < .05). Advance directives were not routinely addressed in the family practice. Most patients preferred to initiate the discussion of advance directives. However, patients who considered the subject extremely important wanted their family doctors to initiate the discussion. Copyright© the College of Family Physicians of Canada.

From the laboratory to the therapy room: National dissemination and implementation of evidence-based psychotherapies in the U.S. Department of Veterans Affairs Health Care System.

Karlin, Bradley E; Cross, Gerald

2014-01-01

Despite their established efficacy and recommendation--often as first-line treatments--in clinical practice guidelines, evidence-based psychotherapies (EBPs) have largely failed to make their way into mainstream clinical settings. Numerous attempts over the years to promote the translation of EBPs from science to practice, typically relying on one-dimensional dissemination approaches, have yielded limited success. As part of the transformation of its mental health care system, the Veterans Health Administration (VHA) of the U.S. Department of Veterans Affairs (VA) is working to disseminate and implement a number of EBPs for various mental and behavioral health conditions throughout the VA health care system. This article examines VHA's multidimensional model and specific strategies, involving policy, provider, local systems, patient, and accountability levels, for promoting the national dissemination and implementation of EBPs in VHA. In addition, the article identifies key lessons learned and next steps for further promoting EBP delivery and sustainability in the VA health care system. Beyond promoting the availability of effective treatments for veterans returning from Iraq and Afghanistan and for veterans of previous combat eras, VHA's EBP dissemination and implementation model and key lessons learned may help to inform other private and public health care systems interested in disseminating and implementing EBPs.

Transforming practice into clinical scholarship.

Limoges, Jacqueline; Acorn, Sonia

2016-04-01

The aims of this paper were to explicate clinical scholarship as synonymous with the scholarship of application and to explore the evolution of scholarly practice to clinical scholarship. Boyer contributed an expanded view of scholarship that recognized various approaches to knowledge production beyond pure research (discovery) to include the scholarship of integration, application and teaching. There is growing interest in using Boyer's framework to advance knowledge production in nursing but the discussion of clinical scholarship in relation to Boyer's framework is sparse. Discussion paper. Literature from 1983-2015 and Boyer's framework. When clinical scholarship is viewed as a synonym for Boyer's scholarship of application, it can be aligned to this well established framework to support knowledge generated in clinical practice. For instance, applying the three criteria for scholarship (documentation, peer review and dissemination) can ensure that the knowledge produced is rigorous, available for critique and used by others to advance nursing practice and patient care. Understanding the differences between scholarly practice and clinical scholarship can promote the development of clinical scholarship. Supporting clinical leaders to identify issues confronting nursing practice can enable scholarly practice to be transformed into clinical scholarship. Expanding the understanding of clinical scholarship and linking it to Boyer's scholarship of application can assist nurses to generate knowledge that addresses clinical concerns. Further dialogue about how clinical scholarship can address the theory-practice gap and how publication of clinical scholarship could be expanded given the goals of clinical scholarship is warranted. © 2016 John Wiley & Sons Ltd.

The purpose of this study was to compare the cortisol responses from a regular season game and a typical practice session in female National Collegiate Athletic Association Division I collegiate soccer players. Eighteen players were assigned to 2 groups, 10 starters and 8 nonstarters, depending on their playing time. Salivary cortisol concentration, as well as competitive sport anxiety (somatic and cognitive anxiety, self-confidence), was monitored before and after 1 regular season game and 1 typical practice session. Although salivary cortisol levels increased postgame for both starters (+250%) and nonstarters (+140%), they increased to a greater extent for the starters. Practice salivary cortisol did not significantly change (p > 0.05). Cognitive and somatic anxiety was greater pre- and postgame when compared with the pre- and postpractice scores, respectively. These data clearly demonstrate the psychological and physiological differences between soccer competition and practice in collegiate women. It appears that both physiological and psychological variables combine to contribute to the large stress hormone response to an actual competitive game.

The Epidemiology and Associated Phenomenology of Formal Thought Disorder: A Systematic Review

2015-01-01

Background: Authors of the Diagnostic and Statistical Manual, Fifth Edition (DSM-V) have recommended to “integrate dimensions into clinical practice.” The epidemiology and associated phenomenology of formal thought disorder (FTD) have been described but not reviewed. We aimed to carry out a systematic review of FTD to this end. Methods: A systematic review of FTD literature, from 1978 to 2013, using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Results: A total of 881 abstracts were reviewed and 120 articles met inclusion criteria; articles describing FTD factor structure (n = 15), prevalence and longitudinal course (n = 41), role in diagnosis (n = 22), associated clinical variables (n = 56), and influence on outcome (n = 35) were included. Prevalence estimates for FTD in psychosis range from 5% to 91%. Dividing FTD into domains, by factor analysis, can accurately identify 91% of psychotic diagnoses. FTD is associated with increased clinical severity. Poorer outcomes are predicted by negative thought disorder, more so than the typical construct of “disorganized speech.” Conclusion: FTD is a common symptom of psychosis and may be considered a marker of illness severity. Detailed dimensional assessment of FTD can clarify diagnosis and may help predict prognosis. PMID:25180313

[Pathological features of myositis with myositis -specific autoantibodies].

PubMed

Shimizu, Jun; Mimori, Tsuneyo

2014-01-01

Myositis is a heterogeneous group of systemic autoimmune disorders characterized by inflammation of skeletal muscle. Historically, myositis has been defined using clinical features including muscle weakness, skin disease, internal organ involvement, and an association with cancer in adults. From a clinicopathologic approach, myositis has been classified into pathologically distinct subsets, polymyositis, dermatomyositis(DM), necrotizing autoimmune myositis, amyopathic DM, and non-specific myositis. Although the characteristic pathological changes are believed to be important in pathological mechanisms of each subset of myositis, in clinical practices, the percentages of the patients with typical pathological findings are usually not high. On the other hand, with the recent discovery of new myositis-specific autoantibodies (MSAs), it has been revealed that around 60% of patients with IIMs have been shown to have a anti-myositis-specific autoantibody, including anti-synthetase, anti-Mi-2, anti-MDA5, anti-TIF1 and anti-SRP antibodies. Because of striking association between unique MSAs and distinct clinical phenotypes, these antibodies are thought to be important not only for classifications of IIMs, but also as factors involved in the mechanism underlying their pathogenesis. This review reports recent progress in understanding of pathological features of myositis with MSAs.

Peroxisome biogenesis disorders in the Zellweger spectrum (PBD-ZSD) are a heterogeneous group of genetic disorders caused by mutations in PEX genes responsible for normal peroxisome assembly and functions. As a result of impaired peroxisomal activities, individuals with PBD-ZSD can manifest a complex spectrum of clinical phenotypes that typically result in shortened life spans. The extreme variability in disease manifestation ranging from onset of profound neurologic symptoms in newborns to progressive degenerative disease in adults presents practical challenges in disease diagnosis and medical management. Recent advances in biochemical methods for newborn screening and genetic testing have provided unprecedented opportunities for identifying patients at the earliest possible time and defining the molecular bases for their diseases. Here, we provide an overview of current clinical approaches for the diagnosis of PBD-ZSD and provide broad guidelines for the treatment of disease in its wide variety of forms. Although we anticipate future progress in the development of more effective targeted interventions, the current guidelines are meant to provide a starting point for the management of these complex conditions in the context of personalized health care.

2017-11-01

Clinical decision support tools for risk prediction are readily available, but typically require workflow interruptions and manual data entry so are rarely used. Due to new data interoperability standards for electronic health records (EHRs), other options are available. As a clinical case study, we sought to build a scalable, web-based system that would automate calculation of kidney failure risk and display clinical decision support to users in primary care practices. We developed a single-page application, web server, database, and application programming interface to calculate and display kidney failure risk. Data were extracted from the EHR using the Consolidated Clinical Document Architecture interoperability standard for Continuity of Care Documents (CCDs). EHR users were presented with a noninterruptive alert on the patient's summary screen and a hyperlink to details and recommendations provided through a web application. Clinic schedules and CCDs were retrieved using existing application programming interfaces to the EHR, and we provided a clinical decision support hyperlink to the EHR as a service. We debugged a series of terminology and technical issues. The application was validated with data from 255 patients and subsequently deployed to 10 primary care clinics where, over the course of 1 year, 569 533 CCD documents were processed. We validated the use of interoperable documents and open-source components to develop a low-cost tool for automated clinical decision support. Since Consolidated Clinical Document Architecture-based data extraction extends to any certified EHR, this demonstrates a successful modular approach to clinical decision support. © The Author 2017.

Initiating decision-making in neurology consultations: 'recommending' versus 'option-listing' and the implications for medical authority.

PubMed

Toerien, Merran; Shaw, Rebecca; Reuber, Markus

2013-07-01

This article compares two practices for initiating treatment decision-making, evident in audio-recorded consultations between a neurologist and 13 patients in two hospital clinics in the UK. We call these 'recommending' and 'option-listing'. The former entails making a proposal to do something; the latter entails the construction of a list of options. Using conversation analysis (CA), we illustrate each, showing that the distinction between these two practices matters to participants. Our analysis centres on two distinctions between the practices: epistemic differences and differences in the slots each creates for the patient's response. Considering the implications of our findings for understanding medical authority, we argue that option-listing - relative to recommending - is a practice whereby clinicians work to relinquish a little of their authority. This article contributes, then, to a growing body of CA work that offers a more nuanced, tempered account of medical authority than is typically portrayed in the sociological literature. We argue that future CA studies should map out the range of ways - in addition to recommending - in which treatment decision-making is initiated by clinicians. This will allow for further evidence-based contributions to debates on the related concepts of patient participation, choice, shared decision-making and medical authority. © 2013 The Authors.

Evidence based practice in clinical physiotherapy education: a qualitative interpretive description

PubMed Central

2013-01-01

Background Health care undergraduate students are expected to practice evidence-based after they graduate. Previous research indicates that students face several problems with transferring evidence-based practice to real patient situations. Few studies have explored reasons for this. The aim of this study was to explore beliefs, experiences and attitudes related to third year students’ use of evidence-based practice in clinical physiotherapy education among students, clinical instructors and visiting teachers. Methods In total, six focus group interviews were conducted: three with 16 students, two with nine clinical instructors and one with four visiting teachers. In addition, one individual interview and one interview in a pair were conducted with clinical instructors. Interviewing three different participant-categories ensured comparative analysis and enabled us to exploit differences in perspectives and interactions. Interpretive description guided this process. Results Four integrative themes emerged from the analysis: “attempt to apply evidence-based practice”, “novices in clinical practice”, “prioritize practice experience over evidence-based practice” and “lack role models in evidence-based practice”. Students tried to search for research evidence and to apply this knowledge during clinical placements; a behaviour that indicated a positive attitude towards evidence-based practice. At the same time, students were novices and required basic background information more than research information. As novices they tended to lean on their clinical instructors, and were more eager to gain practical experience than practicing evidence-based; a behaviour that clinical instructors and visiting teachers often supported. Students noticed a lack of an EBP culture. Both students and clinical instructors perceived a need for role models in evidence-based practice. Conclusions Clinical instructors are in a position to influence students during clinical education, and thus, important potential role models in evidence-based practice. Actions from academic and clinical settings are needed to improve competence in evidence-based practice among clinical instructors, and future research is needed to investigate the effect of such efforts on students’ behaviour.

Implementation of national comprehensive cancer network evidence-based guidelines to prevent and treat cancer-related infections.

PubMed

Wood, Sylvia K; Payne, Judith K

2012-06-01

Clinical practice guidelines are an important result of evidence-based research. However, current clinical practice remains out of step with the rapid pace of research advancements. Often, decades pass before research is translated into clinical practice. The National Comprehensive Cancer Network (NCCN) has created evidence-based clinical guidelines to promote effective clinical practice. Formerly, the NCCN established guidelines to reduce cancer-related infections only for neutropenic patients; however, they have expanded their guidelines beyond neutropenia to prevent and treat cancer-related infections. Implementing scientific evidence into clinical practice is challenging and complex, and healthcare professionals should understand barriers to implementing clinical practice guidelines to ensure successful translation into practice. This article provides a brief review of NCCN guidelines and describes common barriers encountered during implementation. In addition, a conceptual framework is offered to help identify and address potential concerns before and after adoption of guidelines.

Morphologic, Immunophenotypic, and Molecular Features of Epithelial Ovarian Cancer.

PubMed

Ramalingam, Preetha

2016-02-01

Epithelial ovarian cancer comprises a heterogeneous group of tumors. The four most common subtypes are serous, endometrioid, clear cell, and mucinous carcinoma. Less common are transitional cell tumors, including transitional cell carcinoma and malignant Brenner tumor. While in the past these subtypes were grouped together and designated as epithelial ovarian tumors, these tumor types are now known to be separate entities with distinct clinical and biologic behaviors. From a therapeutic standpoint, current regimens employ standard chemotherapy based on stage and grade rather than histotype. However, this landscape may change in the era of personalized therapy, given that most subtypes (with the exception of high-grade serous carcinoma) are relatively resistant to chemotherapy. It is now well-accepted that high-grade and low-grade serous carcinomas represent distinct entities rather than a spectrum of the same tumor type. While they are similar in that patients present with advanced-stage disease, their histologic and molecular features are entirely different. High-grade serous carcinoma is associated with TP53 mutations, whereas low-grade serous carcinomas are associated with BRAF and KRAS mutations. Endometrioid and clear cell carcinomas typically present as early-stage disease and are frequently associated with endometriosis. Mucinous carcinomas typically present as large unilateral masses and often show areas of mucinous cystadenoma and mucinous borderline tumor. It must be emphasized that primary mucinous carcinomas are uncommon tumors, and metastasis from other sites such as the appendix, colon, stomach, and pancreaticobiliary tract must always be considered in the differential diagnosis. Lastly, transitional cell tumors of the ovary, specifically malignant Brenner tumors, are quite uncommon. High-grade serous carcinoma often has a transitional cell pattern, and adequate sampling in most cases shows more typical areas of serous carcinoma. Immunohistochemical markers are routinely employed in the diagnosis of epithelial ovarian carcinomas. However, molecular testing of these tumors, unlike in endometrial carcinoma, is not routinely used in clinical practice.

With the growing accessibility of computer-assisted technology, rehabilitation programs for individuals with cerebral palsy (CP) increasingly use virtual reality environments to enhance motor practice. Thus, it is important to examine whether performance improvements in the virtual environment generalize to the natural environment. To examine this issue, we had 64 individuals, 32 of which were individuals with CP and 32 typically developing individuals, practice two coincidence-timing tasks. In the more tangible button-press task, the individuals were required to 'intercept' a falling virtual object at the moment it reached the interception point by pressing a key. In the more abstract, less tangible task, they were instructed to 'intercept' the virtual object by making a hand movement in a virtual environment. The results showed that individuals with CP timed less accurate than typically developing individuals, especially for the more abstract task in the virtual environment. The individuals with CP did-as did their typically developing peers-improve coincidence timing with practice on both tasks. Importantly, however, these improvements were specific to the practice environment; there was no transfer of learning. It is concluded that the implementation of virtual environments for motor rehabilitation in individuals with CP should not be taken for granted but needs to be considered carefully.

A newly graduated resident faces many new challenges in the first year of practice. Foremost among these is how to handle the newfound wealth that typically accompanies the transition from residency to a successful practice. The ramifications of these decisions are not insignificant. This article explains the important financial considerations a new practitioner must face in the transition from resident to private practice.

Biomarker-Guided Adaptive Trial Designs in Phase II and Phase III: A Methodological Review

PubMed Central

Antoniou, Miranta; Jorgensen, Andrea L; Kolamunnage-Dona, Ruwanthi

2016-01-01

Background Personalized medicine is a growing area of research which aims to tailor the treatment given to a patient according to one or more personal characteristics. These characteristics can be demographic such as age or gender, or biological such as a genetic or other biomarker. Prior to utilizing a patient’s biomarker information in clinical practice, robust testing in terms of analytical validity, clinical validity and clinical utility is necessary. A number of clinical trial designs have been proposed for testing a biomarker’s clinical utility, including Phase II and Phase III clinical trials which aim to test the effectiveness of a biomarker-guided approach to treatment; these designs can be broadly classified into adaptive and non-adaptive. While adaptive designs allow planned modifications based on accumulating information during a trial, non-adaptive designs are typically simpler but less flexible. Methods and Findings We have undertaken a comprehensive review of biomarker-guided adaptive trial designs proposed in the past decade. We have identified eight distinct biomarker-guided adaptive designs and nine variations from 107 studies. Substantial variability has been observed in terms of how trial designs are described and particularly in the terminology used by different authors. We have graphically displayed the current biomarker-guided adaptive trial designs and summarised the characteristics of each design. Conclusions Our in-depth overview provides future researchers with clarity in definition, methodology and terminology for biomarker-guided adaptive trial designs. PMID:26910238

Hassan, Elham A; Hassan, Marwa H; Torad, Faisal A

2018-05-18

The aim of the study was to correlate the clinical severity of pectus excavatum with its type and degree based on objective radiographic evaluation. Twelve brachycephalic dogs were included. Grading of the clinical severity was done based on a 6-point grading score. Thoracic radiographs were used to calculate the frontosagittal and vertebral indices at the tenth thoracic vertebra and the vertebra overlying the excavatum. Correlation between the clinical severity score and frontosagittal and vertebral indices was evaluated using Pearson's correlation coefficient. Typical pectus excavatum was recorded in the caudal sternum in seven dogs, with a mean clinical severity score of 1.7 ± 1.4, whereas in five dogs, atypical mid-sternal deviation was recorded with a mean clinical severity score of 3.8 ± 0.7. A strong correlation (r=0.7) was recorded between the clinical severity score and vertebral index in the atypical form, whereas a weak correlation (r=0.02) was recorded in the typical form (P<0.05). The clinical severity and degree of pectus excavatum was poorly correlated (r=0.3) in the typical form of pectus excavatum, whereas it was strongly correlated (r=0.9) in the atypical form. Pectus excavatum in dogs is associated with compressive cardiopulmonary dysfunction, which depends mainly on the site/type of deviation rather than the degree of deviation.

Corticobasal degeneration (CBD) is a neurodegenerative disease characterized pathologically by neuronal loss, gliosis and tau deposition in neocortex, basal ganglia and brainstem. Typical clinical presentation is known as corticobasal syndrome (CBS) and involves the core features of progressive asymmetric rigidity and apraxia, accompanied by other signs of cortical and extrapyramidal dysfunction. Asymmetry is also emphasized on neuroimaging. To describe a series of cases of CBD with symmetric clinical features and to compare clinical and imaging features of these symmetric CBD cases (S-CBD) to typical cases of CBS with CBD pathology. All cases of pathologically confirmed CBD from the Mayo Clinic Rochester database were identified. Clinical records were reviewed and quantitative volumetric analysis of symmetric atrophy on head MRI using atlas based parcellation was performed. Subjects were classified as S-CBD if no differences had been observed between right- and left-sided cortical or extrapyramidal signs or symptoms. S-CBD cases were compared to 10 randomly selected typical CBS cases. Five cases (2 female) met criteria for S-CBD. None had limb dystonia, myoclonus, apraxia or alien limb phenomena. S-CBD cases had significantly less asymmetric atrophy when compared with CBS cases (p=0.009); they were also younger at onset (median 61 versus 66 years, p<0.05) and death (67 versus 73 years, p<0.05). Family history was present in 40% of S-CBD cases. CBD can have a symmetric presentation, clinically and radiologically, in which typical features of CBS, such as limb apraxia, myoclonus, dystonia and alien limb phenomenon, may be absent.

Engagement and practical wisdom in clinical practice: a phenomenological study.

PubMed

Saraga, Michael; Boudreau, Donald; Fuks, Abraham

2018-05-08

In order to understand the lived experiences of physicians in clinical practice, we interviewed eleven expert, respected clinicians using a phenomenological interpretative methodology. We identified the essence of clinical practice as engagement. Engagement accounts for the daily routine of clinical work, as well as the necessity for the clinician to sometimes trespass common boundaries or limits. Personally engaged in the clinical situation, the clinician is able to create a space/time bubble within which the clinical encounter can unfold. Engagement provides an account of clinical practice as a unitary lived experience. This stands in stark contrast to the prevailing notion, referred to as a dual discourse, that describes medicine as the addition of humanism to science. Drawing on Aristotle's notion of phronesis and Sartre's definition of the situation, we illustrate how this novel perspective entwines clinical practice, the person of the clinician, and the clinician's situation.

Expense comparison of a telemedicine practice versus a traditional clinical practice.

Barker, Gail P; Krupinski, Elizabeth A; Schellenberg, Bonnie; Weinstein, Ronald S

2004-01-01

This paper compares the expenses of a telemedicine program to those of a traditional clinical practice using data from two fiscal years (FY) 1998/1999 and 2000/2001. As part of that evaluation, we compared expenses of the University of Arizona's clinical practice group, the University Physicians Incorporated (UPI), to those of the Arizona Telemedicine Program (ATP) practice. For this study, we used the reporting categories published in the year-end UPI financial statement. These categories included clinical services, administration, equipment depreciation, and overhead. Results showed that clinical service expenses and administrative expenses for FY 2000/2001 were higher in the traditional UPI practice, whereas equipment depreciation and overhead expenses are higher in the telemedicine practice. This differs somewhat from FY 1998/1999, where clinical expenses and overhead were higher in the UPI practice and administration and equipment depreciation were higher in the telemedicine practice. We will discuss the relevance of these results and the critical factors that contribute to these differences.

Shiu, Ann T Y; Lee, Diana T F; Chau, Janita P C

2012-08-01

This article is a report on a study to explore the development of expanding advanced nursing practice in nurse-led clinics in Hong Kong. Nurse-led clinics serviced by advanced practice nurses, a common international practice, have been adopted in Hong Kong since 1990s. Evaluations consistently show that this practice has good clinical outcomes and contributes to containing healthcare cost. However, similar to the international literature, it remains unclear as to what the elements of good advanced nursing practice are, and which directions Hong Kong should adopt for further development of such practice. A multiple-case study design was adopted with six nurse-led clinics representing three specialties as six case studies, and including two clinics each from continence, diabetes and wound care. Each case had four embedded units of analysis. They included non-participant observation of nursing activities (9 days), nurse interviews (N = 6), doctor interviews (N = 6) and client interviews (N = 12). The data were collected in 2009. Within- and cross-case analyses were conducted. The cross-case analysis demonstrated six elements of good advanced nursing practice in nurse-led clinics, and showed a great potential to expand the practice by reshaping four categories of current boundaries, including community-hospital, wellness-illness, public-private and professional-practice boundaries. From these findings, we suggest a model to advance the scope of advanced nursing practice in nurse-led clinics. The six elements may be applied as audit criteria for evaluation of advanced nursing practice in nurse-led clinics, and the proposed model provides directions for expanding such practice in Hong Kong and beyond. © 2011 Blackwell Publishing Ltd.

Cross-sectional study to examine evidence-based practice skills and behaviors of physical therapy graduates: is there a knowledge-to-practice gap?

PubMed

Manns, Patricia J; Norton, Amy V; Darrah, Johanna

2015-04-01

Curricula changes in physical therapist education programs in Canada emphasize evidence-based practice skills, including literature retrieval and evaluation. Do graduates use these skills in practice? The aim of this study was to evaluate the use of research information in the clinical decision making of therapists with different years of experience and evidence-based practice preparation. Perceptions about evidence-based practice were explored qualitatively. A cross-sectional study with 4 graduating cohorts was conducted. Eighty physical therapists representing 4 different graduating cohorts participated in interviews focused on 2 clinical scenarios. Participants had varying years of clinical experience (range=1-15 years) and academic knowledge of evidence-based practice skills. Therapists discussed the effectiveness of interventions related to the scenarios and identified the sources of information used to reach decisions. Participants also answered general questions related to evidence-based practice knowledge. Recent graduates demonstrated better knowledge of evidence-based practice skills compared with therapists with 6 to 15 years of clinical experience. However, all groups used clinical experience most frequently as their source of information for clinical decisions. Research evidence was infrequently included in decision making. This study used a convenience sample of therapists who agreed to volunteer for the study. The results suggest a knowledge-to-practice gap; graduates are not using the new skills to inform their practice. Tailoring academic evidence-based activities more to the time constraints of clinical practice may help students to be more successful in applying evidence in practice. Academic programs need to do more to create and nurture environments in both academic and clinical settings to ensure students practice using evidence-based practice skills across settings. © 2015 American Physical Therapy Association.

Health and well-being in midlife parents of children with special health needs.

Smith, Amy M; Grzywacz, Joseph G

2014-09-01

The objectives of this study were to delineate variation in mental and physical health outcomes over a 10-year period among parents with a child with special health needs as compared to parents of a typically developing child; and evaluate the possible protective effects of parental perceived control and social support. The sample consisted of 646 parents from the longitudinal Midlife Development in the United States (MIDUS) study. Nearly one-quarter of the sample (n = 128; 22.3%) reported having a child with a special health care need. Cross-sectional analyses indicated that parents of a child with special care needs reported poorer self-rated mental health, greater depressive symptoms, and more restrictions in instrumental activities of daily living (IADL). Parents of a child with special health care needs had greater increases in depressive symptoms over time and greater declines in instrumental activities of daily living than parents of typically developing children. Perceived control was a robust predictor of all health outcomes over time. The added stressors of parenting a child with special health needs may undermine the long-term health of parents. Behavioral interventions and clinical practices that facilitate parental perceived control may enable resilience and better health.

New journals for publishing medical case reports.

PubMed

Akers, Katherine G

2016-04-01

Because they do not rank highly in the hierarchy of evidence and are not frequently cited, case reports describing the clinical circumstances of single patients are seldom published by medical journals. However, many clinicians argue that case reports have significant educational value, advance medical knowledge, and complement evidence-based medicine. Over the last several years, a vast number (∼160) of new peer-reviewed journals have emerged that focus on publishing case reports. These journals are typically open access and have relatively high acceptance rates. However, approximately half of the publishers of case reports journals engage in questionable or "predatory" publishing practices. Authors of case reports may benefit from greater awareness of these new publication venues as well as an ability to discriminate between reputable and non-reputable journal publishers.

A picture is worth a thousand lies: using false photographs to create false childhood memories.

2002-09-01

Because image-enhancing technology is readily available, people are frequently exposed to doctored images. However, in prior research on how adults can be led to report false childhood memories, subjects have typically been exposed to personalized and detailed narratives describing false events. Instead, we exposed 20 subjects to a false childhood event via a fake photograph and imagery instructions. Over three interviews, subjects thought about a photograph showing them on a hot air balloon ride and tried to recall the event byusing guided-imagery exercises. Fifty percent of the subjects created complete or partial false memories. The results bear on ways in which false memories can be created and also have practical implications for those involved in clinical and legal settings.

Reconsidering the H&E stain as the gold standard in assessing the depth of burn wounds.

2017-12-01

While histological examination is considered by most as the gold standard for burn depth assessment, it has no practical use in the clinical setting. It has, however, been used in the research setting, as a mean for evaluating emerging techniques of depth measurement. Due to the limitations of the H&E stain, other stains have also been explored, such as lactate dehydrogenase (LDH), as presented in this issue, in "Improving the Histologic Characterization of Burn Depth." As the determination of burn depth is not a typical subject in dermatopathology, a summary of selected techniques and the possible role for the LDH stain in future research, is described herein. © 2017 John Wiley & Sons A/S.

Journal of Psychiatric and Mental Health Nursing 12, 310-316), place increasing emphasis on nurse educators undertaking clinical practice to facilitate their clinical confidence and competence. This study investigated nurse educators' perceptions and experiences of undertaking clinical practice. A qualitative design and descriptive, exploratory approach were used. A purposive sample of 11 nurse educators in one nursing department, took part in two focus group interviews, one with 5 and the other with 6 respondents, to identify and discuss their perceptions and experiences of undertaking clinical practice. A process of thematic content analysis revealed three broad themes relating to the meaning and importance of clinical practice, perceived benefits and barriers which are examined and discussed. The paper concludes that despite policy recommendations, barriers highlighted in this study such as insufficient time, heavy workload and a lack of valuing of the clinical role have been raised over the past few decades. The effect of undertaking clinical practice, particularly on the quality of teaching is argued to be valuable armoury in the battle to secure sufficient resources to support engagement in clinical practice. Financial and organisational commitment; valuing of clinical practice and research evidence are crucial to realising clinical practice for nurse educators. Alternative interpretations of what may constitute the clinical role such as joint research projects and supporting and supervising students are offered, which need to be assessed against clear, specific and realistic aims for the clinical role of the nurse educator.

Although linkage by computer of hospital administration systems across all clinics in a health district is becoming a practical possibility, complete records of general practitioners' referrals to outpatient clinics will be difficult to achieve. Data from a large study of general practitioners' referrals to such clinics were used to calculate the proportion of referrals that crossed district boundaries, the proportion that were made to the private sector; and the number of locations that each practice referred patients to. Of the 17,601 referrals from practices in Oxford Regional Health Authority, 13,857 (78.7%) were made to NHS outpatient clinics within practices' own districts, 1524 (8.7%) to clinics in other districts in the same region, 420 (2.4%) to NHS clinics in other regions, and 1800 (10.2%) to the private sector; but these proportions varied considerably among the practices. The mean number of different NHS hospitals or clinics that each practice referred patients to was 15.8 (range 4-42). PMID:2504414

A framework for promoting scholarship productivity in occupational therapy curricula.

2013-01-01

This paper describes a curricular model to support the production of quality research and development of occupational therapy professional students, prepared to become leaders in the production and utilization of evidence for practice. This model is designed for programs with faculty challenged by the dual mandate of program excellence and expectations for scholarly productivity needed for tenure and promotion: typically programs at research universities. The essence of the model is the paralleling of research and competencies for clinical practice where faculty and students participate as a community of scholars. It is based on the literature that addresses the tensions between achieving excellence in research and scholarly productivity, and excellence in teaching. The experience of one university with this model over a five-year period of time is shared with the student-faculty productivity outcomes. These outcomes include dissemination of 55 collaborative peer reviewed products and faculty has generated support for 25 paid graduate assistantships. The combination of student outcomes and faculty support for their research has strengthened the ability of the faculty to excel in meeting the University mandate of scholarship while providing a high quality professional educational program.

The practice and earnings of preventive medicine physicians.

Salive, M E

1992-01-01

A shortage of preventive medicine (PM) physicians exists in the United States. Researchers know little about these physicians' earnings and practice characteristics. The American College of Preventive Medicine (ACPM) mailed a survey to all self-identified PM physicians on the American Medical Association (AMA) Physician Masterfile. A total of 3,771 (54%) responded; respondents' sex and region of residence were typical for PM physicians in general, with a slight excess of older physicians and those reporting board certification. A total of 2,664 (71%) were working full time, with median earnings of $85,000 (mean $90,000). Among full-time physicians, relatively higher earnings were associated with the following characteristics: male sex; age 45 to 64 years; major source of income from clinical, business, or industrial sources, rather than governmental or academic; and PM board certification. Full-time PM physicians earned much less than office-based private practitioners in several primary care specialties in 1989. The gap in earnings between PM specialists in government positions and those in the private sector is also substantial. Both disparities may require creative solutions.

Patients with multiple myeloma (MM) are typically of an advanced age and may have significant co-existing medical conditions. They have often had multiple lines of therapy and as such experience disease-related effects alongside associated treatment toxicities. Daratumumab is a monoclonal antibody approved for the treatment of MM in the relapsed/refractory setting. Clinical studies found that daratumumab showed good tolerability as a monotherapy and in combination with current standard therapies. However, the administration of daratumumab does require specific management considerations. It is administered as an intravenous infusion and infusion-related reactions (IRRs) may occur. Daratumumab also interferes with routine blood transfusion tests, giving false positives for the indirect antiglobulin test. This article highlights key nursing care considerations and practical management aspects to improve the treatment experience of patients receiving daratumumab infusions. Pretreatment aspects, patient education, pre- and post-medication, daratumumab administration, and the management of IRRs are discussed. An IRR management sheet that could be used by nurses and a patient information sheet are located at the end of this article.

Hybrid Operations in Patients with Peripheral Arterial Disease

PubMed Central

Murakami, Atsubumi

2018-01-01

In this seminar, I would like to discuss the recent hybrid operations in patients with peripheral arterial diseases. Hybrid is generally defined as combinations of different types of things. In the surgical community, it is loosely defined as therapy combining open surgery (OS) and endovascular therapy (EVT). In practice, combination surgery of diseased inflow vessels by EVT and outflow vessels by OS is a typical example, namely, the combination therapy of thromboendarterectomy (TEA) for common femoral artery and EVT (PTA and stenting) for iliac artery in patients with PAD (ilio-femoral lesions). Also, there is the potential of various combinations of OS and EVT for complex lesions. Unfortunately, we do not have specific guidelines for hybrid therapy of PAD, but in clinical practices, justified decision-making for surgical indication is strictly required. I emphasize that the cardiovascular surgeon (or vascular specialist) must have the ability of decision-making for suitable combination therapy of OS and EVT which adheres to existing specific guidelines.

2010-05-01

This article reviews an aspect of daily clinical practice which is of critical importance in virtually every clinical consultation, but which is seldom formally considered. Non-clinical influences on clinical decision-making profoundly affect medical decisions. These influences include patient-related factors such as socioeconomic status, quality of life and patient's expectations and wishes, physician-related factors such as personal characteristics and interaction with their professional community, and features of clinical practice such as private versus public practice as well as local management policies. This review brings together the different strands of knowledge concerning non-clinical influences on clinical decision-making. This aspect of decision-making may be the biggest obstacle to the reality of practising evidence-based medicine. It needs to be understood in order to develop clinical strategies that will facilitate the practice of evidence-based medicine.

2016-12-08

Instead of asking clinicians to work faster or longer to improve quality of care, implementation science provides another option. Implementation science is an emerging interdisciplinary field dedicated to studying how evidence-based practice can be adopted into routine clinical care. This article summarizes principles and methods of implementation science, illustrates how they can be applied in a routine clinical setting, and highlights their importance to practicing clinicians as well as clinical trainees. A hypothetical clinical case scenario is presented that explains how implementation science improves clinical practice. The case scenario is also embedded within a real-world implementation study to improve metabolic monitoring for individuals prescribed antipsychotics. Context, recipient, and innovation (ie, the evidence-based practice) factors affected improvement of metabolic monitoring. To address these factors, an external facilitator and a local quality improvement team developed an implementation plan involving a multicomponent implementation strategy that included education, performance reports, and clinician follow-up. The clinic remained compliant with recommended metabolic monitoring at 1-year follow up. Implementation science improves clinical practice by addressing context, recipient, and innovation factors and uses this information to develop and utilize specific strategies that improve clinical practice. It also enriches clinical training, aligning with core competencies by the Accreditation Council for Graduate Medical Education and American Boards of Medical Specialties. By learning how to change clinical practice through implementation strategies, clinicians are more able to adapt in complex systems of practice. © Copyright 2016 Physicians Postgraduate Press, Inc.

The increasing practicality of genomic sequencing technology has led to its incorporation into routine clinical practice. Successful identification and targeting of driver genomic alterations that provide proliferative and survival advantages to tumor cells have led to approval and ongoing development of several targeted cancer therapies. Within many major cancer centers, molecular tumor boards are constituted to shepherd precision medicine into clinical practice. In July 2014, the Clinical Genomics Action Committee (CGAC) was established as the molecular tumor board companion to the Personalized Medicine Clinical Service (PMCS) at Moffitt Cancer Center in Tampa, Florida. The processes and outcomes of the program were assessed in order to help others move into the practice of precision medicine. Through the establishment and initial 1,400 patients of the PMCS and its associated molecular tumor board at a major cancer center, five practical lessons of broad applicability have been learned: transdisciplinary engagement, the use of the molecular report as an aid to clinical management, clinical actionability, getting therapeutic options to patients, and financial considerations. Value to patients includes access to cutting-edge practice merged with individualized preferences in treatment and care. Genomic-driven cancer medicine is increasingly becoming a part of routine clinical practice.

Edlow, Richard C

2015-01-01

Medical practices are under significant pressure to provide superior customer service in an environment of declining or flat reimbursement. The solution for many practices involves the integration of a variety of third-party technologies that conveniently interface with one's electronic practice management and medical records systems. Typically, the applications allow the practice to reduce the cost of each patient interaction. Drilling down to quantify the cost of each individual patient interaction helps to determine the practicality of implementation.

Introduction to fragment-based drug discovery.

PubMed

Erlanson, Daniel A

2012-01-01

Fragment-based drug discovery (FBDD) has emerged in the past decade as a powerful tool for discovering drug leads. The approach first identifies starting points: very small molecules (fragments) that are about half the size of typical drugs. These fragments are then expanded or linked together to generate drug leads. Although the origins of the technique date back some 30 years, it was only in the mid-1990s that experimental techniques became sufficiently sensitive and rapid for the concept to be become practical. Since that time, the field has exploded: FBDD has played a role in discovery of at least 18 drugs that have entered the clinic, and practitioners of FBDD can be found throughout the world in both academia and industry. Literally dozens of reviews have been published on various aspects of FBDD or on the field as a whole, as have three books (Jahnke and Erlanson, Fragment-based approaches in drug discovery, 2006; Zartler and Shapiro, Fragment-based drug discovery: a practical approach, 2008; Kuo, Fragment based drug design: tools, practical approaches, and examples, 2011). However, this chapter will assume that the reader is approaching the field with little prior knowledge. It will introduce some of the key concepts, set the stage for the chapters to follow, and demonstrate how X-ray crystallography plays a central role in fragment identification and advancement.

Approximately 24% of stroke survivors experience co-occurring aphasia and hemiparesis. These individuals typically attend back-to-back therapy sessions. However, sequentially scheduled therapy may trigger physical and mental fatigue and have an adverse impact on treatment outcomes. The current study tested a hypothesis that exerting less effort during a therapy session would reduce overall fatigue and enhance functional recovery. Two stroke survivors chronically challenged by non-fluent aphasia and right hemiparesis sequentially completed verbal naming and upper-limb tasks on their home computers. The level of cognitive-linguistic effort in speech/language practice was manipulated by presenting verbal naming tasks in two conditions: Decreasing cues (i.e., most-to-least support for word retrieval), and Increasing cues (i.e., least-to-most support). The participants completed the same upper-limb exercises throughout the study periods. Both individuals showed a statistically significant advantage of decreasing cues over increasing cues in word retrieval during the practice period, but not at the end of the practice period or thereafter. The participant with moderate aphasia and hemiparesis achieved clinically meaningful gains in upper-limb functions following the decreasing cues condition, but not after the increasing cues condition. Preliminary findings from the current study suggest a positive impact of decreasing cues in the context of multidisciplinary stroke rehabilitation.

To explore how nurse researchers in clinical positions experience the presence of a nursing research culture in clinical practice. Higher demands in the hospitals for increasing the quality of patient care engender a higher demand for the skills of health professionals and evidence-based practice. However, the utilisation of nursing research in clinical practice is still limited. Intrinsic single case study design underlined by a constructivist perspective. Data were produced through a focus group interview with seven nurse researchers employed in clinical practice in two university hospitals in Zealand, Denmark, to capture the intrinsic aspects of the concept of nursing research culture in the context of clinical practice. A thematic analysis was conducted based on Braun and Clarke's theoretical guideline. "Caught between a rock and a hard place" was constructed as the main theme describing how nurse researchers in clinical positions experience the presence of a nursing research culture in clinical practice. The main theme was supported by three subthemes: Minimal academic tradition affects nursing research; Minimal recognition from physicians affects nursing research; and Moving towards a research culture. The nurse researchers in this study did not experience the presence of a nursing research culture in clinical practice, however; they called for more attention on removing barriers against research utilisation, promotion of applied research and interdisciplinary research collaboration, and passionate management support. The results of this case study show the pressure which nurse researchers employed in clinical practice are exposed to, and give examples on how to accommodate the further development of a nursing research culture in clinical practice. © 2017 John Wiley & Sons Ltd.

'Can he have the test for bipolar, doctor? His dad's got it': exploring the potential of general practitioners to work with children and young people presenting in primary care with common mental health problems - a clinical initiative.

PubMed

Roberts, Jane H; Bernard, Paul M

2012-06-01

Background General practitioners (GPs) play a key role in assessing and managing adult mental health problems, but this input is not seen in their management of child and adolescent mental health. Mental health problems in 5-19-year-olds are common, yet detection rates in primary care are low. The symptoms of most adult diagnoses of mental health problems are present by mid-adolescence, yet the typical time from onset to diagnosis is 5-15 years. The role of general practice in this area has been underexplored. Aim This pilot study explores the potential of GPs to respond to common mental health problems in children and adolescents. Design Children and young people who would have ordinarily been referred to Child and Adolescent Mental Health Services (CAMHS) were seen in a GP setting. In a UK general practice surgery serving a disadvantaged population. Method Children and young people were seen for an initial biopsychosocial assessment and formulation of the presenting concerns. GP-based interventions were offered as appropriate or referred to CAMHS. Results Data from the first 50 children (2-19 years) are presented. Twenty younger children (10 years and under) and 30 older children (11 years and above) were seen. Eighteen referrals were made to CAMHS. GP interventions included watchful waiting, brief behavioural interventions, non-directive counselling, brief cognitive- behavioural therapy (CBT) and liaison with colleagues in education, CAMHS and the voluntary sector. Conclusion This clinical pilot demonstrates that with adequate time, access to supervision and practice support, children and young people experiencing emotional and behavioural problems associated with common mental health issues can be helped in primary care.

Statistics teaching in medical school: opinions of practising doctors.

2010-11-04

The General Medical Council expects UK medical graduates to gain some statistical knowledge during their undergraduate education; but provides no specific guidance as to amount, content or teaching method. Published work on statistics teaching for medical undergraduates has been dominated by medical statisticians, with little input from the doctors who will actually be using this knowledge and these skills after graduation. Furthermore, doctor's statistical training needs may have changed due to advances in information technology and the increasing importance of evidence-based medicine. Thus there exists a need to investigate the views of practising medical doctors as to the statistical training required for undergraduate medical students, based on their own use of these skills in daily practice. A questionnaire was designed to investigate doctors' views about undergraduate training in statistics and the need for these skills in daily practice, with a view to informing future teaching. The questionnaire was emailed to all clinicians with a link to the University of East Anglia Medical School. Open ended questions were included to elicit doctors' opinions about both their own undergraduate training in statistics and recommendations for the training of current medical students. Content analysis was performed by two of the authors to systematically categorize and describe all the responses provided by participants. 130 doctors responded, including both hospital consultants and general practitioners. The findings indicated that most had not recognised the value of their undergraduate teaching in statistics and probability at the time, but had subsequently found the skills relevant to their career. Suggestions for improving undergraduate teaching in these areas included referring to actual research and ensuring relevance to, and integration with, clinical practice. Grounding the teaching of statistics in the context of real research studies and including examples of typical clinical work may better prepare medical students for their subsequent career.

Executive abilities in children with congenital visual impairment in mid-childhood.

2018-02-01

The role of vision and vision deprivation in the development of executive function (EF) abilities in childhood is little understood; aspects of EF such as initiative, attention orienting, inhibition, planning and performance monitoring are often measured through visual tasks. Studying the development and integrity of EF abilities in children with congenital visual impairment (VI) may provide important insights into the development of EF and also its possible relationship with vision and non-visual senses. The current study investigates non-visual EF abilities in 18 school-age children of average verbal intelligence with VI of differing levels of severity arising from congenital disorders affecting the eye, retina, or anterior optic nerve. Standard auditory neuropsychological assessments of sustained and divided attention, phonemic, semantic and switching verbal fluency, verbal working memory, and ratings of everyday executive abilities by parents were undertaken. Executive skills were compared to age-matched typically-sighted (TS) typically-developing children and across levels of vision (mild to moderate VI [MVI] or severe to profound VI [SPVI]). The results do not indicate significant differences or deficits on direct assessments of verbal and auditory EF between the groups. However, parent ratings suggest difficulties with everyday executive abilities, with the greatest difficulties in those with SPVI. The findings are discussed as possibly reflecting increased demands of behavioral executive skills for children with VI in everyday situations despite auditory and verbal EF abilities in the typical range for their age. These findings have potential implications for clinical and educational practices.

[Science and ethics, therapeutic misconception and mirage].

PubMed

Raymond, J; Long, H

2008-12-01

Medical practice changes constantly. Ethical imperatives are however incorrigible. How can we reconcile ethics, practice and progress? Some bioethicians argue that research and care should be disentangled to minimize the 'therapeutic misconception', a clinical propensity to believe that patients are the object of medical care, while in fact they are the subjects of a scientific experiment. On the contrary, we believe that clinical research should be an integral part of the good practice. A divorce between research and clinical practice leads to an incorrigible medicine, liable to the therapeutic mirage, that is the false belief that everything modern medicine can offer has been proved beneficial. But both therapeutic misconception and mirage are possible because of a misunderstanding of either research or clinical practice. In this essay we review ethical principles behind clinical trial methodology and attempt to reconcile ethics, science and clinical practice. Not only should clinical research be integrated to the good practice of medicine, it should also be part of training in our specialty.

[Clinical practice guidelines (II): searching and critical evaluation].

PubMed

Alonso, P; Bonfill, X

2007-01-01

Clinical practice guidelines have unique characteristics of the Internet era in which they are starting to be increasingly popular. The fact that they are often elaborated by governmental agencies and are not published in conventional journals means that they may not be accessible using the usual search methods employed for other types of scientific studies and documents (clinical trials, reviews, etc.). The Internet has become an essential tool for locating clinical practice guidelines, and meta-search engines, specific databases, directories, and elaborating institutions are of special importance. The relative lack of indexing of clinical practice guides means that Medline and Embase are not as useful in this context as in searching for original studies. With the aim of evaluating the validity, reproducibility, and reliability of clinical practice guidelines, a series of European institutions designed a tool to evaluate clinical practice guidelines at the end of the 1990s. This instrument, named AGREE, aims to offer a framework for the evaluation of the quality of clinical practice guidelines. It can also be useful in the design of new clinical practice guidelines as well as in the evaluation of the validity of guidelines to be updated or adapted. The AGREE instrument has become the reference for those that use guidelines, those that elaborate them, and for healthcare providers.

Practice of clinical forensic medicine in Sri Lanka: does it need a new era?

PubMed

Kodikara, Sarathchandra

2012-07-01

Clinical forensic medicine is a sub-specialty of forensic medicine and is intimately associated with the justice system of a country. Practice of clinical forensic medicine is evolving, but deviates from one jurisdiction to another. Most English-speaking countries practice clinical forensic medicine and forensic pathology separately while most non-English-speaking countries practice forensic medicine which includes clinical forensic medicine and forensic pathology. Unlike the practice of forensic pathology, several countries have informal arrangements to deal with forensic patients and there are no international standards of practice or training in this discipline. Besides, this is rarely a topic of discussion. In the adversarial justice system in Sri Lanka, the designated Government Medical Officers practice both clinical forensic medicine and forensic pathology. Practice of clinical forensic medicine, and its teaching and training in Sri Lanka depicts unique features. However, this system has not undergone a significant revision for many decades. In this communication, the existing legal framework, current procedure of practice, examination for drunkenness, investigations, structure of referrals, reports, subsequent legal procedures, undergraduate, in-service, and postgraduate training are discussed with suggestions for reforms.

To elicit perceptions of midwifery graduates regarding the impact of Enquiry Based Learning (EBL) on their clinical practice. A qualitative approach utilising semi-structured interviews and content analysis. A midwifery education provider in the Republic of Ireland. Purposive sampling was employed to recruit fourteen midwifery graduates, from a total of twenty eight, from two cohorts who had successfully completed a Higher Diploma in Midwifery programme. Findings centred on the theme 'Effect of EBL on clinical practice', with positive perceptions of EBL reported in relation to its connexion to midwifery practice. Findings affirm the view that EBL augments linkage of theory to clinical practice in addition to linking clinical practice to theory. Consequently, competent practitioners are cultivated and an array of transferable skills developed, thus demonstrating the significant contribution of EBL in enriching clinical practice.

BACKGROUND This study aimed to elucidate how clinical preventive services are delivered in family practices and how this information might inform improvement efforts. METHODS We used a comparative case study design to observe clinical preventive service delivery in 18 purposefully selected Midwestern family medicine offices from 1997 to 1999. Medical records, observation of outpatient encounters, and patient exit cards were used to calculate practice-level rates of delivery of clinical preventive services. Field notes from direct observation of clinical encounters and prolonged observation of the practice and transcripts from in-depth interviews of practice staff and physicians were systematically examined to identify approaches to delivering clinical preventive services recommended by the US Preventive Services Task Force. RESULTS Practices developed individualized approaches for delivering clinical preventive services, with no one approach being successful across practices. Clinicians acknowledged a 3-fold mission of providing acute care, managing chronic problems, and prevention, but only some made prevention a priority. The clinical encounter was a central focus for preventive service delivery in all practices. Preventive services delivery rates often appeared to be influenced by competing demands within the clinical encounter (including between different preventive services), having a physician champion who prioritized prevention, and economic concerns. CONCLUSIONS Practice quality improvement efforts that assume there is an optimal approach for delivering clinical preventive services fail to account for practices’ propensity to optimize care processes to meet local contexts. Interventions to enhance clinical preventive service delivery should be tailored to meet the local needs of practices and their patient populations. PMID:16189059

Developability assessment of clinical drug products with maximum absorbable doses.

PubMed

Ding, Xuan; Rose, John P; Van Gelder, Jan

2012-05-10

Maximum absorbable dose refers to the maximum amount of an orally administered drug that can be absorbed in the gastrointestinal tract. Maximum absorbable dose, or D(abs), has proved to be an important parameter for quantifying the absorption potential of drug candidates. The purpose of this work is to validate the use of D(abs) in a developability assessment context, and to establish appropriate protocol and interpretation criteria for this application. Three methods for calculating D(abs) were compared by assessing how well the methods predicted the absorption limit for a set of real clinical candidates. D(abs) was calculated for these clinical candidates by means of a simple equation and two computer simulation programs, GastroPlus and an program developed at Eli Lilly and Company. Results from single dose escalation studies in Phase I clinical trials were analyzed to identify the maximum absorbable doses for these compounds. Compared to the clinical results, the equation and both simulation programs provide conservative estimates of D(abs), but in general D(abs) from the computer simulations are more accurate, which may find obvious advantage for the simulations in developability assessment. Computer simulations also revealed the complex behavior associated with absorption saturation and suggested in most cases that the D(abs) limit is not likely to be achieved in a typical clinical dose range. On the basis of the validation findings, an approach is proposed for assessing absorption potential, and best practices are discussed for the use of D(abs) estimates to inform clinical formulation development strategies.

Deciding when to biopsy a man with non-suspicious DRE findings and tPSA in the 4-10 ng/ml range can be challenging, because two-thirds of such biopsies are typically found to be benign. The Prostate Health Index (phi) exhibits significantly improved diagnostic accuracy for prostate cancer detection when compared to tPSA and %fPSA, however only one published study to date has investigated its impact on biopsy decisions in clinical practice. An IRB approved observational study was conducted at four large urology group practices using a physician reported two-part questionnaire. Physician recommendations were recorded before and after receiving the phi test result. A historical control group was queried from each site's electronic medical records for eligible men who were seen by the same participating urologists prior to the implementation of the phi test in their practice. 506 men receiving a phi test were prospectively enrolled and 683 men were identified for the historical control group (without phi). Biopsy and pathological findings were also recorded for both groups. Men receiving a phi test showed a significant reduction in biopsy procedures performed when compared to the historical control group (36.4% vs. 60.3%, respectively, P < 0.0001). Based on questionnaire responses, the phi score impacted the physician's patient management plan in 73% of cases, including biopsy deferrals when the phi score was low, and decisions to perform biopsies when the phi score indicated an intermediate or high probability of prostate cancer (phi ≥36). phi testing significantly impacted the physician's biopsy decision for men with tPSA in the 4-10 ng/ml range and non-suspicious DRE findings. Appropriate utilization of phi resulted in a significant reduction in biopsy procedures performed compared to historical patients seen by the same participating urologists who would have met enrollment eligibility but did not receive a phi test.

Salmonella enterica is the most commonly reported cause of outbreaks of nosocomial infections in large animal veterinary teaching hospitals and the closure of equine hospitals. Rapid detection may facilitate effective control practices in equine populations. Shipping and laboratory testing typically require ≥48 h to obtain results. Lateral flow immunoassays developed for use in food-safety microbiology provide an alternative that has not been evaluated for use with faeces or environmental samples. We aimed to identify enrichment methods that would allow commercially available rapid Salmonella detection systems (lateral flow immunoassays) to be used in clinical practice with equine faecal and environmental samples, providing test results in 18-24 h. In vitro experiment. Equine faecal and environmental samples were inoculated with known quantities of S. enterica serotype Typhimurium and cultured using 2 different enrichment techniques for faeces and 4 enrichment techniques for environmental samples. Samples were tested blindly using 2 different lateral flow immunoassays and plated on agar media for confirmatory testing. In general, commercial lateral flow immunoassays resulted in fewer false-negative test results with enrichment of 1 g faecal samples in tetrathionate for 18 h, while all environmental sample enrichment techniques resulted in similar detection rates. The limit of detection from spiked samples, ∼4 colony-forming units/g, was similar for all methods evaluated. The lateral flow immunoassays evaluated could reliably detect S. enterica within 18 h, indicating that they may be useful for rapid point-of-care testing in equine practice applications. Additional evaluation is needed using samples from naturally infected cases and the environment to gain an accurate estimate of test sensitivity and specificity and to substantiate further the true value of these tests in clinical practice. © 2014 EVJ Ltd.

Clinical research program managers are regularly faced with the quandary of determining how much of a workload research staff members can manage while they balance clinical practice and still achieve clinical trial accrual goals, maintain data quality and protocol compliance, and stay within budget. A tool was developed to measure clinical trial-associated workload, to apply objective metrics toward documentation of work, and to provide clearer insight to better meet clinical research program challenges and aid in balancing staff workloads. A project was conducted to assess the feasibility and utility of using this tool in diverse research settings. Community-based research programs were recruited to collect and enter clinical trial-associated monthly workload data into a web-based tool for 6 consecutive months. Descriptive statistics were computed for self-reported program characteristics and workload data, including staff acuity scores and number of patient encounters. Fifty-one research programs that represented 30 states participated. Median staff acuity scores were highest for staff with patients enrolled in studies and receiving treatment, relative to staff with patients in follow-up status. Treatment trials typically resulted in higher median staff acuity, relative to cancer control, observational/registry, and prevention trials. Industry trials exhibited higher median staff acuity scores than trials sponsored by the National Institutes of Health/National Cancer Institute, academic institutions, or others. The results from this project demonstrate that trial-specific acuity measurement is a better measure of workload than simply counting the number of patients. The tool was shown to be feasible and useable in diverse community-based research settings. Copyright © 2016 by American Society of Clinical Oncology.

Muthathi, Immaculate S; Thurling, Catherine H; Armstrong, Susan J

Clinical facilitation is an essential part of the undergraduate nursing curriculum. A number of studies address the issue of clinical facilitation in South Africa, but there remains a lack of knowledge and understanding regarding what students perceive as best practice in clinical facilitation of their learning. To determine what type of clinical facilitation undergraduate students believe should be offered by clinical facilitators (nurse educators, professional nurses and clinical preceptors) in the clinical area in order to best facilitate their learning. A qualitative, exploratory and descriptive study was conducted. Purposive sampling was performed to select nursing students from the second, third and fourth year of studies from a selected nursing education institution in Johannesburg. The sampling resulted in one focus group for each level of nursing, namely second, third and fourth year nursing students. Interviews were digitally recorded and transcribed verbatim, thematic data analysis was used and trustworthiness was ensured by applying credibility, dependability, confirmability and transferability. The data revealed that participants differentiated between best practices in clinical facilitation in the clinical skills laboratory and clinical learning environment. In the clinical skills laboratory, pre-contact preparation, demonstration technique and optimising group learning were identified as best practices. In the clinical learning environment, a need for standardisation of procedures in simulation and practice, the allocation and support for students also emerged. There is a need for all nurses involved in undergraduate nursing education to reflect on how they approach clinical facilitation, in both clinical skills laboratory and clinical learning environment. There is also a need to improve consistency in clinical practices between the nursing education institution and the clinical learning environment so as to support students' adaptation to clinical practice.

Background Clinical care team members in Department of Veterans' Affairs (VA) facilities nationwide are working to integrate the use of Secure Messaging (SM) into care delivery and identify innovative uses. Identifying best practices for proactive use of SM is a key factor in its successful implementation and sustained use by VA clinical care team members and veterans. Objectives A collaborative project solicited input from VA clinical care teams about their local practices using SM to provide access to proactive patient-centered care for veterans and enhance workflow. Methods This project implemented a single-item cross-sectional qualitative electronic survey via internal e-mail to local coordinators in all 23 Veterans Integrated Service Networks (VISNs). Content analysis was used to manage descriptive data responses. Descriptive statistics described sample characteristics. Results VA clinical care team members across 15 of 23 VISNs responded to the questionnaire. Content analysis of 171 responses produced two global domains: (1) benefits of SM and (2) SM best practices. Benefits of SM use emphasize enhanced and efficient communication and increased access to care. Care team members incorporate SM into their daily clinical practices, using it to provide services before, during, and after clinical encounters as a best practice. SM users suggest improvements in veteran care, clinical team workflow, and efficient use of health resources. Clinical team members invested in the successful implementation of SM integrate SM into their daily practices to provide meaningful and useful veteran-centered care and improve workflow. Conclusion VA clinical care team members can use SM proactively to create an integrated SM culture. With adequate knowledge and motivation to proactively use this technology, all clinical team members within the VA system can replicate best practices shared by other clinical care teams to generate meaningful and useful interactions with SM to enrich veterans' health care experience.

Configurations of leadership practices in hospital units.

PubMed

Meier, Ninna

2015-01-01

The purpose of this paper is to explore how leadership is practiced across four different hospital units. The study is a comparative case study of four hospital units, based on detailed observations of the everyday work practices, interactions and interviews with ten interdisciplinary clinical managers. Comparing leadership as configurations of practices across four different clinical settings, the author shows how flexible and often shared leadership practices were embedded in and central to the core clinical work in all units studied here, especially in more unpredictable work settings. Practices of symbolic work and emotional support to staff were particularly important when patients were severely ill. Based on a study conducted with qualitative methods, these results cannot be expected to apply in all clinical settings. Future research is invited to extend the findings presented here by exploring leadership practices from a micro-level perspective in additional health care contexts: particularly the embedded and emergent nature of such practices. This paper shows leadership practices to be primarily embedded in the clinical work and often shared across organizational or professional boundaries. This paper demonstrated how leadership practices are embedded in the everyday work in hospital units. Moreover, the analysis shows how configurations of leadership practices varied in four different clinical settings, thus contributing with contextual accounts of leadership as practice, and suggested "configurations of practice" as a way to carve out similarities and differences in leadership practices across settings.

Advanced practice nursing role delineation in acute and critical care: application of the strong model of advanced practice.

PubMed

Mick, D J; Ackerman, M H

2000-01-01

This purpose of this study was to differentiate between the roles of clinical nurse specialists and acute care nurse practitioners. Hypothesized blending of the clinical nurse specialist and acute care nurse practitioner roles is thought to result in an acute care clinician who integrates the clinical skills of the nurse practitioner with the systems knowledge, educational commitment, and leadership ability of the clinical nurse specialist. Ideally, this role blending would facilitate excellence in both direct and indirect patient care. The Strong Model of Advanced Practice, which incorporates practice domains of direct comprehensive care, support of systems, education, research, and publication and professional leadership, was tested to search for practical evidence of role blending. This descriptive, exploratory, pilot study included subjects (N = 18) solicited from an academic medical center and from an Internet advanced practice listserv. Questionnaires included self-ranking of expertise in practice domains, as well as valuing of role-related tasks. Content validity was judged by an expert panel of advanced practice nurses. Analyses of descriptive statistics revealed that clinical nurse specialists, who had more experience both as registered nurses and in the advanced practice nurse role, self-ranked their expertise higher in all practice domains. Acute care nurse practitioners placed higher importance on tasks related to direct comprehensive care, including conducting histories and physicals, diagnosing, and performing diagnostic procedures, whereas clinical nurse specialists assigned greater importance to tasks related to education, research, and leadership. Levels of self-assessed clinical expertise as well as valuing of role-related tasks differed among this sample of clinical nurse specialists and acute care nurse practitioners. Groundwork has been laid for continuing exploration into differentiation in advanced practice nursing roles. As the clinical nurse specialist role changes and the acute care nurse practitioner role emerges, it is imperative that advanced practice nurses describe their contribution to health care. Associating advanced practice nursing activities with outcomes will help further characterize these 2 advanced practice roles.

Main outcome measures were rehospitalisation rates, mean hospital bed days, mean length of stay, cost of inpatient and pharmaceutical care to the sickness fund during follow-up and medication used to treat side-effects. 3121 patients were included into the study. There were no statistically significant differences in the effectiveness of atypical and typical antipsychotics on rehospitalisation during follow-up (rehospitalisation rate ratio 1.07, 95% confidence interval 0.86 to 1.33). However, there were consistent observations of atypical antipsychotics being more effective for severe cases of schizophrenia (14.6% of study population; >61 prior bed days per year in 2000-2002) in the follow-up period, whereas for the other severity strata typical antipsychotics seemed more effective in reducing various rehospitalisation outcomes. Patients treated with atypical antipsychotics received significantly less prescriptions for anticholinergics or tiaprid (relative risk 0.26, 95% confidence interval 0.18 to 0.38). The effectiveness of atypical antipsychotics for schizophrenia on rehospitalisation measures appeared similar to that of typical antipsychotics. With the exception of severe cases, the higher costs for atypical antipsychotics were not offset by savings from reduced inpatient care. Major limitations include the lack of statistical power for subgroup analyses, the lack of clinical severity scale data and of life-course medical history data which both increase the risk of residual confounding by disease severity. This study provides evidence that the effectiveness of atypical and typical antipsychotics measured in terms of hospital readmissions appears to be similar in routine care. From a clinical perspective, this study provides evidence that the effectiveness of atypical and typical antipsychotics measured in terms of hospital readmissions appears to be similar in routine care. Routine data studies can yield valuable information for policy decision-makers on the costs and the effectiveness of pharmaceuticals in routine care, complementing efficacy data from randomised clinical trials currently used for licensing and reimbursement decisions. The non-significant differences in the effectiveness of atypical compared to typical antipsychotics according to severity of disease should be investigated in a prospective observational study or in a randomised clinical trial.

Clinical Skills Assessment in the Twenty-First Century.

Clinical skills remain fundamental to the practice of medicine and form a core component of the professional identity of the physician. However, evidence exists to suggest that the practice of some clinical skills is declining, particularly in the United States. A decline in practice of any skill can lead to a decline in its teaching and assessment, with further decline in practice as a result. Consequently, assessment not only drives learning of clinical skills, but their practice. This article summarizes contemporary approaches to clinical skills assessment that, if more widely adopted, could support the maintenance and reinvigoration of bedside clinical skills.

In South Africa, first-contact primary care is delivered by nurses in small clinics and larger community health centres (CHC). CHCs also employ doctors, who often work in isolation from the nurses, with poor differentiation of roles and little effective teamwork or communication. Worcester CHC, a typical public sector CHC in rural South Africa, decided to explore how to create more successful practice teams of doctors and nurses. This paper is based on their experience of both unsuccessful and successful attempts to introduce practice teams and reports on their learning regarding organisational change. An emergent action research study design utilised a co-operative inquiry group. The first nine months of inquiry focused on understanding the initial unsuccessful attempt to create practice teams. This paper reports primarily on the subsequent nine months (four cycles of planning, action, observation and reflection) during which practice teams were re-introduced. The central question was how more effective practice teams of doctors and nurses could be created. The group utilised outcome mapping to assist with planning, monitoring and evaluation. Outcome mapping defined a vision, mission, boundary partners, outcome challenges, progress markers and strategies for the desired changes and supported quantitative monitoring of the process. Qualitative data were derived from the co-operative inquiry group (CIG) meetings and interviews with doctors, nurses, practice teams and patients. The CIG engaged effectively with 68% of the planned strategies, and more than 60% of the progress markers were achieved for clinical nurse practitioners, doctors, support staff and managers, but not for patients. Key themes that emerged from the inquiry group's reflection on their experience of the change process dealt with the amount of interaction, type of communication, team resilience, staff satisfaction, leadership style, reflective capacity, experimentation and evolution of new structures. The group's learning supported a view of change that sees the organisation as a living system in which information flow, participation and the development of resilience are key aspects. These themes fit well into an understanding of change based on complexity theory. If managers of the health system wish to enhance organisational change, then their goal may need to shift from optimising health care delivery in a mechanistic model to optimising health care workers in a living system.

Essentials Warfarin typically requires International Normalized Ratio (INR) testing at least every 4 weeks. We implemented extended INR testing for stable warfarin patients in six anticoagulation clinics. Use of extended INR testing increased from 41.8% to 69.3% over the 3 year study. Use of extended INR testing appeared safe and effective. Background A previous single-center randomized trial suggested that patients with stable International Normalized Ratio (INR) values could safely receive INR testing as infrequently as every 12 weeks. Objective To test the success of implementation of an extended INR testing interval for stable warfarin patients in a practice-based, multicenter collaborative of anticoagulation clinics. Methods At six anticoagulation clinics, patients were identified as being eligible for extended INR testing on the basis of prior INR value stability and minimal warfarin dose changes between 2014 and 2016. We assessed the frequency with which anticoagulation clinic providers recommended an extended INR testing interval (> 5 weeks) to eligible patients. We also explored safety outcomes for eligible patients, including next INR values, bleeding events, and emergency department visits. Results At least one eligible period for extended INR testing was identified in 890 of 3362 (26.5%) warfarin-treated patients. Overall, the use of extended INR testing in eligible patients increased from 41.8% in the first quarter of 2014 to 69.3% in the fourth quarter of 2016. The number of subsequent out-of-range next INR values were similar between eligible patients who did and did not have an extended INR testing interval (27.3% versus 28.4%, respectively). The numbers of major bleeding events were not different between the two groups, but rates of clinically relevant non-major bleeding (0.02 per 100 patient-years versus 0.09 per 100 patient-years) and emergency department visits (0.07 per 100 patient-years versus 0.19 per 100 patient-years) were lower for eligible patients with extended INR testing intervals than for those with non-extended INR testing intervals. Conclusions Extended INR testing for stable warfarin patients can be successfully and safely implemented in diverse, practice-based anticoagulation clinic settings. © 2018 International Society on Thrombosis and Haemostasis.

Consensus statements and clinical practice guidelines are widely available for enhancing the care of cancer patients. Despite subtle differences in their definition and purpose, these terms are often used interchangeably. We systematically assessed the methodological quality of consensus statements and clinical practice guidelines published in three commonly read, geographically diverse, cancer-specific journals. Methods Consensus statements and clinical practice guidelines published between January 2005 and September 2013 in Current Oncology, European Journal of Cancer and Journal of Clinical Oncology were evaluated. Each publication was assessed using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) rigour of development and editorial independence domains. For assessment of transparency of document development, 7 additional items were taken from the Institute of Medicine's standards for practice guidelines and the Journal of Clinical Oncology guidelines for authors of guidance documents. Consensus statements and clinical practice guidelines published between January 2005 and September 2013 in Current Oncology, European Journal of Cancer and Journal of Clinical Oncology were evaluated. Each publication was assessed using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) rigour of development and editorial independence domains. For assessment of transparency of document development, 7 additional items were taken from the Institute of Medicine's standards for practice guidelines and the Journal of Clinical Oncology guidelines for authors of guidance documents. Thirty-four consensus statements and 67 clinical practice guidelines were evaluated. The rigour of development score for consensus statements over the three journals was 32% lower than that of clinical practice guidelines. The editorial independence score was 15% lower for consensus statements than clinical practice guidelines. One journal scored consistently lower than the others over both domains. No journals adhered to all the items related to the transparency of document development. One journal's consensus statements endorsed a product made by the sponsoring pharmaceutical company in 64% of cases. Guidance documents are an essential part of oncology care and should be subjected to a rigorous and validated development process. Consensus statements had lower methodological quality than clinical practice guidelines using AGREE II. At a minimum, journals should ensure that that all consensus statements and clinical practice guidelines adhere to AGREE II criteria. Journals should consider explicitly requiring guidelines to declare pharmaceutical company sponsorship and to identify the sponsor's product to enhance transparency.

Pediatric syncope is common. Cardiac causes are rarely found. We describe and assess a pragmatic approach to these patients first seen by a pediatric cardiologist in the New England region, using Standardized Clinical Assessment and Management Plans (SCAMPs). Ambulatory patients aged 7 to 21 years initially seen for syncope at participating New England Congenital Cardiology Association practices over a 2.5-year period were evaluated using a SCAMP. Findings were iteratively analyzed and the care pathway was revised. The vast majority (85%) of the 1254 patients had typical syncope. A minority had exercise-related or more problematic symptoms. Guideline-defined testing identified one patient with cardiac syncope. Syncope Severity Scores correlated well between physician and patient perceived symptoms. Orthostatic vital signs were of limited use. Largely incidental findings were seen in 10% of ECGs and 11% of echocardiograms. The 10% returning for follow-up, by design, reported more significant symptoms, but did not have newly recognized cardiac disease. Iterative analysis helped refine the approach. SCAMP methodology confirmed that the vast majority of children referred to the outpatient pediatric cardiology setting had typical low-severity neurally mediated syncope that could be effectively evaluated in a single visit using minimal resources. A simple scoring system can help triage patients into treatment categories. Prespecified criteria permitted the effective diagnosis of the single patient with a clear cardiac etiology. Patients with higher syncope scores still have a very low risk of cardiac disease, but may warrant attention. © 2016 The Authors.

High-throughput laboratory technologies coupled with sophisticated bioinformatics algorithms have tremendous potential for discovering novel biomarkers, or profiles of biomarkers, that could serve as predictors of disease risk, response to treatment or prognosis. We discuss methodological issues in wedding high-throughput approaches for biomarker discovery with the case-control study designs typically used in biomarker discovery studies, especially focusing on nested case-control designs. We review principles for nested case-control study design in relation to biomarker discovery studies and describe how the efficiency of biomarker discovery can be effected by study design choices. We develop a simulated prostate cancer cohort data set and a series of biomarker discovery case-control studies nested within the cohort to illustrate how study design choices can influence biomarker discovery process. Common elements of nested case-control design, incidence density sampling and matching of controls to cases are not typically factored correctly into biomarker discovery analyses, inducing bias in the discovery process. We illustrate how incidence density sampling and matching of controls to cases reduce the apparent specificity of truly valid biomarkers 'discovered' in a nested case-control study. We also propose and demonstrate a new case-control matching protocol, we call 'antimatching', that improves the efficiency of biomarker discovery studies. For a valid, but as yet undiscovered, biomarker(s) disjunctions between correctly designed epidemiologic studies and the practice of biomarker discovery reduce the likelihood that true biomarker(s) will be discovered and increases the false-positive discovery rate. © 2012 The Authors.
