  1. Clinical equipoise: actual or hypothetical disagreement?

    PubMed

    Gelfand, Scott

    2013-12-01

    In his influential 1987 essay, "Equipoise and The Ethics of Randomized Clinical Research," Benjamin Freedman argued that Charles Fried's theoretical equipoise requirement threatened clinical research because it was overwhelmingly fragile and rendered unethical too many randomized clinical trials. Freedman, therefore, proposed an alternative requirement, the clinical equipoise requirement, which is now considered to be the fundamental or guiding principle concerning the ethics of enrolling patients in randomized clinical trials. In this essay I argue that Freedman's clinical equipoise requirement is ambiguous and can be interpreted in (at least) two different ways. I furthermore claim that, ironically, the best interpretation of the clinical equipoise requirement opens Freedman to the same objection that he leveled against Fried twenty-five years ago; namely, that it (Freedman's clinical equipoise requirement) renders unethical too many randomized clinical trials.

  2. Telemedicine in clinical setting

    The telemedicine department of a hospital is an emerging branch in upcoming hospitals and may become an essential component of every hospital. It basically utilizes the information technologies along with telecommunication systems in order to provide clinical care and assistance. Furthermore, the branch of telemedicine offers significant opportunities for the process of developmental freedom from illness, early death, and preventable diseases. It advances development by providing relevant drugs and the necessary care aimed to alleviate patient suffering. It is also beneficial for patients in rural remote areas who usually do not have adequate access to advanced hospitals. Telemedicine in these remote areas allows for timely treatment of emergency cases. Thus, it contributes towards remote emergency critical care in order to save lives in crucial cases. Additionally, the emerging advances have now enabled telemedicine to transfer large amounts of clinical informatics data including images, and test reports to the specifically specialized health professionals in some serious cases. However, as in the case of many emerging technologies, organizing information and understanding the field has significant challenges. The present review article aimed to discuss important aspects of the field with regard to the better management of patients in clinical settings. PMID:27703503

  5. Optimal maintenance and consolidation therapy for multiple myeloma in actual clinical practice

    PubMed Central

    Lee, Ho Sup; Min, Chang-Ki

    2016-01-01

    Multiple myeloma is an incurable malignant plasma cell-originating cancer. Although its treatment outcomes have improved with the use of glucocorticoids, alkylating drugs, and novel agents, including proteasome inhibitors (bortezomib and carfilzomib) and immunomodulatory drugs (thalidomide, lenalidomide, and pomalidomide), relapse remains a serious problem. Strategies to improve outcomes following autologous stem cell transplantation and frontline treatments in non-transplant patients include consolidation to intensify therapy and improve the depth of response and maintenance therapy to achieve long-term disease control. Many clinical trials have reported increased progression-free and overall survival rates after consolidation and maintenance therapy. The role of consolidation/maintenance therapy has been assessed in patients eligible and ineligible for transplantation and is a valuable option in clinical trial settings. However, the decision to use consolidation and/or maintenance therapy needs to be guided by the individual patient situation in actual clinical practice. This review analyzes the currently available evidence from several reported clinical trials to determine the optimal consolidation and maintenance therapy in clinical practice. PMID:27604793

    Infrared eye tracker has been demonstrated to provide a more objective and quantitative results of the cover test measurement in eye care practices. This paper reviews the application of eye trackers in oculary clinical setting. It highlights the different types of eye movement recording system (EMRS) available, the advantages and disadvantages of each and their use in a clinical setting. This paper also discusses the parameters that can be derived from the EMRS and the significance of the parameters in a clinical interpretation. Using an eye tracker would make available to the clinician a simple system for making quantitative measurements when performing the cover test in an eye examination.

    2012-01-01

    Context Occult hepatitis B (OHB), or persistent HBV DNA in patients who are hepatitis B surface antigen (HBsAg) negative, is a recently recognized entity. In an attempt to summarize the issues, this review presents an overview of the current proposed hypothesis on the clinical relevance and also updates the knowledge on the classification of OHB in different clinical settings. Evidence Acquisition OHB could be found in different population and clinical backgrounds including: viral co-infections (with either human immunodeficiency or hepatitis C viruses), HBV chronic carriers, dialysis patients, transplantation settings and certain clinical situations (named in here: special clinical settings) with no apparent distinguishable clinical parameters. Results The exact magnitude, pathogenesis, and clinical relevance of OHB are unclear. Even the possible role exerted by this cryptic infection on liver disease outcome, and hepatocellular carcinoma development remains unknown. Conclusions Monitoring of Individuals with positive anti-HBc, mass immunization programs and improvement in diagnostic tools seem to be important to control the probability of transmission of HBV through cryptic HBV infection.

  9. A new adaptation of linear reservoir models in parallel sets to assess actual hydrological events

    NASA Astrophysics Data System (ADS)

    Mateo Lázaro, Jesús; Sánchez Navarro, José Ángel; García Gil, Alejandro; Edo Romero, Vanesa

    2015-05-01

    A methodology based on Parallel Linear Reservoir (PLR) models is presented. To carry it out has been implemented within the software SHEE (Simulation of Hydrological Extreme Events), which is a tool for the analysis of hydrological processes in catchments with the management and display of DEM and datasets. The algorithms of the models pass throughout the cells and drainage network, by means of the Watershed Traversal Algorithm (WTA) that runs the entire drainage network of a basin in both directions, upwards and downwards, which is ideal for incorporating the models of the hydrological processes of the basins into its structure. The WTA methodology is combined with another one based on models of Parallel Linear Reservoirs (PLR) whose main qualities include: (1) the models are defined by observing the recession curves of actual hydrographs, i.e., the watershed actual responses; (2) the models serve as a way to simulate the routing through the watershed and its different reservoirs; and (3) the models allow calculating the water balance, which is essential to the study of actual events in the watershed. A complete hydrometeorological event needs the combination of several models, each one of which represents a hydrological process. The PLR model is a routing model, but it also contributes to the adjustment of other models (e.g., the rainfall-runoff model) and allows establishing a distributed model of effective rainfall for an actual event occurred in a basin. On the other hand, the proposed formulation solves the rainfall distribution problem for each deposit in the reservoir combination models.

    2016-03-01

    This study deals with student nurses' experiences of collaborative learning in gerontological clinical settings where aged people are involved as age-experts in students' learning processes. The data were collected in 2012 using the contents of students' reflective writing assignments concerning elderly persons' life history interviews and the students' own assessments of their learning experiences in authentic elder care settings. The results, analyzed using qualitative content analysis, revealed mostly positive learning experiences. Interaction and collaborative learning activities in genuine gerontological clinical settings contributed to the students' understanding of the multiple age-related and disease-specific challenges as well as the issues of functional decline that aged patients face. Three types of factors influenced the students' collaborative learning experiences in gerontological clinical settings: student-related, patient-related and learning environment-related factors. According to the results, theoretical studies in combination with collaboration, in an authentic clinical environment, by student nurses, elderly patients, representatives of the elder care staff and nurse educators provide a feasible method for helping students transform their experiences with patients into actual skills. Their awareness of and sensitivity to the needs of the elderly increase as they learn.

  12. Actual Versus Estimated Utility Factor of a Large Set of Privately Owned Chevrolet Volts

    2014-04-01

    In order to determine the overall fuel economy of a plug-in hybrid electric vehicle (PHEV), the amount of operation in charge depleting (CD) versus charge sustaining modes must be determined. Mode of operation is predominantly dependent on customer usage of the vehicle and is therefore highly variable. The utility factor (UF) concept was developed to quantify the distance a group of vehicles has traveled or may travel in CD mode. SAE J2841 presents a UF calculation method based on data collected from travel surveys of conventional vehicles. UF estimates have been used in a variety of areas, including the calculation of window sticker fuel economy, policy decisions, and vehicle design determination. The EV Project, a plug-in electric vehicle charging infrastructure demonstration being conducted across the United States, provides the opportunity to determine the real-world UF of a large group of privately owned Chevrolet Volt extended range electric vehicles. Using data collected from Volts enrolled in The EV Project, this paper compares the real-world UF of two groups of Chevrolet Volts to estimated UF's based on J2841. The actual observed fleet utility factors (FUF) for the MY2011/2012 and MY2013 Volt groups studied were observed to be 72% and 74%, respectively. Using the EPA CD ranges, the method prescribed by J2841 estimates a FUF of 65% and 68% for the MY2011/2012 and MY2013 Volt groups, respectively. Volt drivers achieved higher percentages of distance traveled in EV mode for two reasons. First, they had fewer long-distance travel days than drivers in the national travel survey referenced by J2841. Second, they charged more frequently than the J2841 assumption of once per day - drivers of Volts in this study averaged over 1.4 charging events per day. Although actual CD range varied widely as driving conditions varied, the average CD ranges for the two Volt groups studied matched the EPA CD range estimates, so CD range variation did not affect FUF results.

    2016-01-01

    INTRODUCTION This study examines the relationship between the clinical performance of medical students and their performance as doctors during their internships. METHODS This retrospective study involved 63 applicants of a residency programme conducted at Chonnam National University Hospital, South Korea, in November 2012. We compared the performance of the applicants during their internship with their clinical performance during their fourth year of medical school. The performance of the applicants as interns was periodically evaluated by the faculty of each department, while their clinical performance as fourth-year medical students was assessed using the Clinical Performance Examination (CPX) and the Objective Structured Clinical Examination (OSCE). RESULTS The performance of the applicants as interns was positively correlated with their clinical performance as fourth-year medical students, as measured by the CPX and OSCE. The performance of the applicants as interns was moderately correlated with the patient-physician interaction items addressing communication and interpersonal skills in the CPX. CONCLUSION The clinical performance of medical students during their fourth year in medical school was related to their performance as medical interns. Medical students should be trained to develop good clinical skills through actual encounters with patients or simulated encounters using manikins, to enable them to become more competent doctors.

    Abstract Ladder inclined angle is a critical factor that could lead to a slip at the base of portable straight ladders, a major cause of falls from heights. Despite several methods established to help workers achieve the recommended 75.5° angle for ladder set-up, it remains unclear if these methods are used in practice. This study explored ladder set-up behaviours in a field environment. Professional installers of a company in the cable and other pay TV industry were observed for ladder set-up at their worksites. The results showed that the actual angles of 265 ladder set-ups by 67 participants averaged 67.3° with a standard deviation of 3.22°. Although all the participants had training on recommended ladder set-up methods, only 3 out of 67 participants applied these methods in their daily work and even they failed to achieve the desired 75.5° angle. Therefore, ladder set-up remains problematic in real-world situations. Practitioner Summary: Professional installers of a cable company were observed for portable straight ladder set-up at their worksites. The ladder inclined angle averaged 67.3° with a standard deviation of 3.22°, while the recommended angle is 75.5°. Only a few participants used the methods that they learned during training in their daily work. PMID:26672809

    Background: Providing holistic nursing care when there is a shortage of personnel and equipment exposes nurses to stress and a higher risk of occupational burnout. Humour can promote nurses’ health and influence nursing care. The aim of this study was to describe nurses’ experiences of humour in clinical settings and factors affecting it. Methods: This qualitative study investigated nurses’ experiences of humour. Five hospitals affiliated to Tehran University of Medical Sciences provided the setting for this study. The participants comprised of 17 nurses with master’s and Baccalaureate degrees (BSN) in nursing. These nurses worked at educational hospitals affiliated to Tehran University of Medical Sciences and had minimum work experience of 12 months in various clinical wards. Nurses from all wards were invited to participate in this study. The data were collected through semi structure interviews using guides comprising probing questions. Telephonic interviews were used to further supplement the data. The data were analysed using conventional content analysis. Results: The data were classified into five themes including the dynamics of humour, condition enforcement, Risk making probability, Instrumental use and Change: opportunities and threats. Conclusion: Understanding nurses’ perceptions and experiences of humour helps identify its contributing factors and provides valuable guidelines for enhancing nurses and patients’ mental, emotional and physical health. Spreading a culture of humour through teaching methods can improve workplace cheerfulness and highlights the importance of humour in patient care in nurses and nursing students. PMID:26034735

  17. The Physics of a Volcanic System: What is the Actual Role Played by Tectonic Setting in Controlling Volcanic Activity?

    2005-12-01

    Modern text-books commonly explain volcanic activity as a direct consequence of plate tectonics, overlooking the different scales characteristic of both types of processes. By acknowledging such differences, however, it is possible to envisage a model of a volcanic system that is based in the same principles of hydrostatics established by Blaise Pascal over 300 yrs ago. Such principles allow us to estimate the local conditions required for the occurrence of volcanism at a given location highlighting the importance of the rock strength and the density difference between melt and its surroundings. This model shows that the minimum thickness of the zone of partial melting in the mantle (or seismically defined Low Velocity Zone) that is required to feed volcanic activity might range from 5 to over 100 km, but also that under certain circumstances a rock strength < 200 MPa may suffice to keep magma trapped at depth whereas in other cases a strength > 600 MPa will not suffice to stop magma ascent resulting in volcanic activity at the surface. Consequently, the model of volcanism developed here explains why is that a given LVZ may lead to volcanic activity in some places whereas a completely identical LVZ may not result in volcanic activity in a different location. Consequently, this model provides a general framework that allows us to better understand the actual role played by tectonic setting in controlling volcanism at a planetary scale.

    Rhinosinusitis (RS) is a heterogeneous group of diseases. It is a significant and increasing health problem that affects about 15% of the population in Western countries. It has a substantial impact on patients' health-related quality of life and daily functioning and represents a huge financial burden to society and the health care system as a result of the direct and indirect costs. In addition, RS is not well-understood, and little is known about the etiology and pathophysiology. In the past decade, many papers have been published that have changed our understanding of RS. RS is commonly classified into acute and chronic RS based on symptom duration. In acute RS, an inflammatory reaction initiated by a viral infection characterizes most uncomplicated, mild to moderate cases. Therefore, the first line of treatment for these cases are intranasal steroids and not antibiotics. In severe and complicated cases, antibiotics combined with topical steroids remain the treatment of choice. On the other hand, chronic RS is actually subdivided into two distinct entities (chronic rhinosinusitis with and without polyps), as growing evidence indicates that these entities have specific inflammatory pathways and cytokine profiles. The authors review recent data regarding the clinical presentations, cytokine profiles, tissue remodeling, and modalities of treatment for each form of RS.

    Diffuse gliomas are a heterogeneous group of malignancies with highly variable outcomes, and diagnosis is largely based on histologic appearance. Tumor classification according to cell type and grade provides some prognostic information. However, significant clinical and biologic heterogeneity exists in glioma, even after accounting for known clinicopathologic variables. Significant advances in knowledge of the molecular genetics of brain tumors have occurred in the past decade, largely because of the availability of high-throughput profiling techniques, including new sequencing methodologies and multidimensional profiling by The Cancer Genome Atlas project. The large amount of data generated from these efforts has enabled the identification of prognostic and predictive factors and helped to identify pathways driving tumor growth. Implementing these signatures into the clinic to personalize therapy presents a new challenge. Identification of relevant biomarkers, especially when coupled with clinical trials of newer targeted therapies, will enable better patient stratification and individualization of treatment for patients with glioma.

  20. Evidence supporting primary prevention of cardiovascular diseases with statins: Gaps between updated clinical results and actual practice.

    2014-03-01

    The use of pharmacological lipid-lowering intervention in individuals with hypercholesterolaemia and known cardiovascular disease or diabetes/chronic kidney disease is well established. Current European Society of Cardiology guidelines recommend immediate initiation of drugs in adjunct to lifestyle intervention in these patients at high or very high cardiovascular risk. In these clinical settings, statins are generally chosen as the first-choice drug intervention, in consideration of the robust evidence showing a reduction in all-cause mortality and major adverse cardiac events (MACE). In contrast, primary prevention with statins, even in the subset of patients at high-risk of cardiovascular events, is not well implemented. This might be related to a lack of public awareness regarding the actual risk associated with prolonged exposure to high concentrations of low-density lipoprotein cholesterol (LDL-C) and uncertainties in the clinical evidence coming from the earliest trials in this patient subset. However, recent observational studies suggest that lowering LDL-C earlier in life and for a longer duration can substantially decrease the burden of cardiovascular disease and mortality. Moreover, results from recent well-conducted large meta-analyses of randomized clinical trials showed that primary prevention with statins reduced all-cause mortality by 14% and MACE by > 20% - findings similar to those observed for the use of statins in secondary prevention. Recently published American Heart Association/American College of Cardiology guidelines on the treatment of blood cholesterol emphasize that primary prevention using high-dose statins in individuals with LDL-C ≥ 190 mg/dL induces a benefit in atherosclerotic cardiovascular risk reduction that clearly exceeds the potential for adverse effects. We aim in this review to discuss the new data that advocate the use of statins in primary prevention earlier and more frequently, putting the efficacy evidence into

    2010-07-01

    The explosive growth of automatic examination of the eye, in particular for determining refractive corrections, invites an analysis of the strengths and limitations of these devices and their role in clinical decisions. Subjective refraction procedures are based on a patient's visual responses and these embrace many levels of additional optical and neural processing and factors involving the higher-order nervous system and perception. Because the ultimate mission is the maintenance and improvement of a patient's visual experiences, the optometric examination necessarily extends beyond the employment of automatic devices and therefore, should include engaging the patients in tests of their visual functions.

    2008-09-01

    The purpose of this article is to propose a screening procedure to assess venous insufficiency with a hand-held photoplethysmography (PPG) instrument in the clinical setting. PPG is noninvasive technology that is used as part of venous assessment of the lower extremities. Although duplex ultrasound remains the industry gold standard for assessment, there are many situations in which access or expertise is not available. The measurement of venous refill time with PPG, one measure of venous insufficiency, is becoming increasingly more prevalent in research settings; however, PPG is underused in clinical settings. Rapid venous refill time clinical settings as a screening mechanism may provide useful data to augment diagnostic and therapeutic decision making. Future research is needed to establish a best-practice guideline for venous assessment in clinical settings to validate using PPG.

    Over the last century, much has been learned about the pathogenesis, manifestations, and management of Graves' disease leading to the establishment of evidence-based clinical practice guidelines. The joint clinical practice guidelines from the American Thyroid Association and the American Association of Clinical Endocrinologists give recommendations on both the diagnosis and treatment of hyperthyroidism. A survey of clinicians performed that same year, however, revealed that current practices diverge from these recently published guidelines in multiple areas. These differences will need to be assessed serially to determine the impact of the guidelines on future clinical practice and perhaps vice versa.

    While evidence continues to accumulate on the relevance of cognitive inflexibility in anorexia nervosa (AN), its clinical correlates remain unclear. We aimed at examining the relationship between set-shifting and clinical variables (i.e., eating psychopathology, depression, and personality) in AN. Ninety-four individuals affected by AN and 59 healthy controls (HC) were recruited. All participants were assessed using: Eating Disorders Inventory-2 (EDI-2), Temperament and Character Inventory (TCI), Beck Depression Inventory (BDI), and Wisconsin Card Sorting Test (WCST). The AN group scored worse than HCs on set-shifting. According to their neuropsychological performances, AN patients were split into two groups corresponding to poor (N=30) and intact (N=64) set-shifting subtypes. Interoceptive awareness, impulse regulation, and maturity fears on the EDI-2 and depression on the BDI differed across all groups (HC, intact, and poor set-shifting subtype). Self-directedness on the TCI differed significantly among all groups. Cooperativeness and reward dependence differed instead only between HC and AN poor set-shifting subtype. After controlling for depression, only interoceptive awareness remained significant with reward dependence showing a trend towards statistical significance. These findings suggest that multiple clinical variables may be correlated with set-shifting performances in AN. The factors contributing to impaired cognitive inflexibility could be more complex than heretofore generally considered.

    Objective To compare the outcomes of cognitive therapy for depression under controlled and clinically representative conditions, while holding several therapist and clinical assessment factors constant. Method Treatment outcomes for a sample of 23 adults with a primary diagnosis of Major Depressive Disorder who received cognitive therapy in an outpatient clinic were compared with outcomes of 18 clients who were treated in the cognitive therapy condition of a large, multi-site randomized clinical trial of treatments for depression. All participants had been treated by one of two therapists who served as clinicians in both settings. Individuals in the two samples were diagnostically and demographically similar (approximately 50% Female, 83% White). A variety of client characteristics, assessed prior to treatment, as well as the outcomes of treatment, were examined. Results Significantly superior treatment outcomes were observed in the individuals treated in the research study, relative to clients in the outpatient clinic, and the difference was not accounted for by intake characteristics. Individuals treated by the therapists in the RCT experienced almost three times as much improvement in depressive symptoms as clients seen in the outpatient setting. Conclusions If replicated, the findings suggest that differences exist between treatment outcomes in research and outpatient settings and that these differences may not simply be due to therapist experience and training, or differences in patient populations. Future research should further examine the impact of fidelity monitoring, treatment expectation and motivation, and the duration and timing of treatment protocols on clinical outcomes. PMID:23710102

    There is no doubt that emotions have an important effect on practices of moral reasoning such as clinical ethics consultation. Empathy is not only a basic human emotion but also an important and learnable skill for health care professionals. A basic amount of empathy is essential both in patient care and in clinical ethics consultation. This article debates the "adequate dose" of empathy in ethics consultations in clinical settings and tries to identify possible situations within the process of consultation in which this crucial feeling is at risk.

  9. Would Socrates Have Actually Used the "Socratic Method" for Clinical Teaching?

    2016-09-01

    Medical students and residents are familiar with clinical teaching methods in which a faculty member poses a series of questions to them. This technique is often called the "Socratic method," but it is frequently perceived by learners as an attempt to demean them, a practice that is colloquially known as "pimping." The distinction between Socratic teaching and pimping lies in the perception of "psychological safety." Psychological safety allows learners to answer questions or ask for help without threats to their dignity or worthiness. In a psychologically safe clinical teaching context, learners recognize that questions posed by attending physicians probe their current understanding and guide them to expand their knowledge. In pimping, questions are posed to embarrass the learner and to reinforce the teacher's position of power over them. Absent a threat of disparagement or condemnation, learners are able to focus on building schema for knowledge, skills, and attitudes, rather than worrying about shielding their self-worth. This article presents the proper Socratic method, as intended by Socrates, and contrasts it with pimping. This perspective defines psychological safety as the pivotal factor distinguishing Socratic teaching from pimping, and establishes the foundation for empirical studies of these common practices in medical education.

    The origin of pathogenic Enteroaggregative Escherichia coli (EAEC), a major causative agent of childhood diarrhea worldwide, remains ill-defined. The objective of this study was to determine the relative prevalence of EAEC in clinical and non-clinical sources and compare their genetic characteristics in order to identify strains that rarely and commonly cause human diarrhea. The virulence gene astA was commonly detectable in both clinical and non-clinical EAEC, while clinical isolates, but not the non-clinical strains, were consistently found to harbor other virulence factors such as aap (32%), aatA (18%) and aggR (11%). MLST analysis revealed the extremely high diversity of EAEC ST types, which can be grouped into three categories including: (i) non-clinical EAEC that rarely cause human infections; (ii) virulent strains recoverable in diarrhea patients that are also commonly found in the non-clinical sources; (iii) organisms causing human infections but rarely recoverable in the non-clinical setting. In addition, the high resistance in these EAEC isolates in particular resistance to fluoroquinolones and cephalosporins raised a huge concern for clinical EAEC infection control. The data from this study suggests that EAEC strains were diversely distributed in non-clinical and clinical setting and some of the clinical isolates may originate from the non-clinical setting.

    The rapidly expanding use of electronic records in health-care settings is generating unprecedented quantities of data available for clinical, epidemiological, and cost-effectiveness research. Several challenges are associated with using these data for clinical research, including issues surrounding access and information security, poor data quality, inconsistency of data within and across institutions, and a paucity of staff with expertise to manage and manipulate large clinical data sets. In this article, we describe our experience with assembling a data-mart and conducting clinical research using electronic data from four facilities within a single hospital network in New York City. We culled data from several electronic sources, including the institution's admission-discharge-transfer system, cost accounting system, electronic health record, clinical data warehouse, and departmental records. The final data-mart contained information for more than 760,000 discharges occurring from 2006 through 2012. Using categories identified by the National Institutes of Health Big Data to Knowledge initiative as a framework, we outlined challenges encountered during the development and use of a domain-specific data-mart and recommend approaches to overcome these challenges.

    The difficulties in establishing and delivering reliable clinical hematology and laboratory services in resource-limited settings are well recognized. However, much can be achieved by better use of existing resources through a concerted quality improvement approach. The recommendations of this article are based in part upon work in the thalassemias, inherited disorders of hemoglobin that are widely prevalent in Asia, which may serve as a model that is applicable to other common, chronic disorders in resource-poor settings. Available resources are highlighted and recommendations made regarding approaches to improving services. Over the last few years, a number of low and middle-income countries, obtaining support from appropriate governmental sources, have identified and overcome difficulties and significantly improved clinical services for patients with thalassemia.

  16. Estimating the re-identification risk of clinical data sets

    PubMed Central

    2012-01-01

    Background De-identification is a common way to protect patient privacy when disclosing clinical data for secondary purposes, such as research. One type of attack that de-identification protects against is linking the disclosed patient data with public and semi-public registries. Uniqueness is a commonly used measure of re-identification risk under this attack. If uniqueness can be measured accurately then the risk from this kind of attack can be managed. In practice, it is often not possible to measure uniqueness directly, therefore it must be estimated. Methods We evaluated the accuracy of uniqueness estimators on clinically relevant data sets. Four candidate estimators were identified because they were evaluated in the past and found to have good accuracy or because they were new and not evaluated comparatively before: the Zayatz estimator, slide negative binomial estimator, Pitman’s estimator, and mu-argus. A Monte Carlo simulation was performed to evaluate the uniqueness estimators on six clinically relevant data sets. We varied the sampling fraction and the uniqueness in the population (the value being estimated). The median relative error and inter-quartile range of the uniqueness estimates was measured across 1000 runs. Results There was no single estimator that performed well across all of the conditions. We developed a decision rule which selected between the Pitman, slide negative binomial and Zayatz estimators depending on the sampling fraction and the difference between estimates. This decision rule had the best consistent median relative error across multiple conditions and data sets. Conclusion This study identified an accurate decision rule that can be used by health privacy researchers and disclosure control professionals to estimate uniqueness in clinical data sets. The decision rule provides a reliable way to measure re-identification risk. PMID:22776564

    In a clinical setting, where motor-driven systems are not readily available, the major difficulty in the assessment of the stretch reflex lies in the control of passive limb displacement velocity. A potential approach to this problem arises from the use of manual sinusoidal movements (made by continuous alternating flexions and extensions) paced by an external stimulus. Unfortunately, there are conditions in which sinusoidal movements induce interfering phenomena such as the shortening reaction or postactivation depression. In the present paper, a novel manual method to control the velocity of passive linear movements is described and the results obtained from both healthy subjects and spastic patients are reported. This method is based on the synchronisation of movements with tones played by a metronome at different speeds. In a first set of experiments performed in healthy subjects, we demonstrated consistent control of velocity during passive limb movements using this method. Four joints usually examined during muscle tone assessment were tested: wrist, elbow, knee and ankle joints. Following this, we conducted a longitudinal assessment of the stretch reflex amplitude in wrist flexor muscles in patients with spasticity treated with botulinum toxin type A. The evaluators were not only able to vary the movement velocity based on the metronome speed, but also could reproduce the respective speeds two weeks later, despite the changing degree of hypertonia. This method is easy to perform in a clinical setting and hardware requirements are minimal, making it an attractive and robust procedure for the widespread clinical assessment of reflex hypertonia.

    In order to compare a newly established diagnostic clinic with two existing clinical settings in the management of the diagnostic phase of multiple sclerosis (MS), a retrospective audit was performed over a 12-month period comparing the length of time, adherence to recently published standards and price charged in diagnosing MS in three different clinical diagnostic settings operating within the same hospital: a specifically designed demyelinating disease diagnostic clinic (DDC), a general neurology clinic (GNC) and an inpatient investigation unit (IIU). An audit tool was created to measure the standards advocated by the UK MS Society on management of the diagnostic phase of MS. The costing tool was the price charged to health authorities. A randomized retrospective case note and referral letter review method was used. The entry criterion was a confirmed diagnosis of MS documented in the medical notes following investigation during the period April 1999-April 2001. The time between referral and first appointment favoured the DDC with a mean time of 5.9 weeks, compared to 7.7 weeks for the GNC and 10.0 weeks for the IIU. The mean times between the first appointment and receipt of results were 4.7 weeks (DDC), 18.8 weeks (GNC) and 21.2 weeks (IIU). Prices ranged from pounds sterling 395-pounds sterling 790 (DDC), pounds sterling 95-pounds sterling 380 (GNC) and pounds sterling 1940-pounds sterling 2700 (IIU). This study suggests that the UK MS Society standards are achievable in most areas without excessive additional costs and provides evidence that the DDC offers a better service than other existing models.

    Most older adults diagnosed with a mental disorder receive treatment in primary care settings that lack personnel skilled in geropsychological diagnosis and treatment. The Ferkauf Older Adult Program of Yeshiva University endeavors to bridge this gap by providing training in geriatric psychology, through coursework and diverse clinical practica, to clinical psychology doctoral students within a large urban professional psychology program. In an innovative effort to provide the most disadvantaged elderly with comprehensive mental health treatment and maximize trainee exposure to an interdisciplinary treatment model, the program also pairs selected doctoral psychology trainees with medical residents to optimize integrated mental health service delivery for primary care elderly. The program has the following core objectives: (1) Infuse the mental health and aging knowledge base into the regular graduate curriculum; (2) Provide interdisciplinary training in geropsychological diagnostic and consultative services within an urban primary care setting; (3) Provide interdisciplinary training in the practice of psychological and neuropsychological evaluation of elderly; (4) Provide training in geropsychological psychotherapeutic intervention, including individual, couples/family, and brief/psycho-educational therapies with outpatient older adults. These objectives are achieved by pooling the resources of a graduate school of psychology, a local public hospital, and an academic medical center to achieve educational and clinical service goals.

  20. Integrative Nursing: Application of Principles Across Clinical Settings

    PubMed Central

    Kreitzer, Mary Jo

    2015-01-01

    While the essence of nursing has long been whole person (body, mind, and spirit) and whole system-focused, in reality the contemporary practice of nursing in many settings around the globe has become increasingly fragmented and de-stabilized. Nursing shortages in many parts of the world are significant, and hierarchies and bureaucracies often remove nurses from the point of care, be that the bedside, home, or clinic, replacing them with less skilled workers and filling their time with documentation and other administrative tasks. Integrative nursing is a framework for providing whole person/whole system care that is relationship-based and person-centered and focuses on improving the health and wellbeing of caregivers as well as those they serve. It is aligned with what is being called the “triple aim” in the United States—an effort focused on improving the patient experience (quality and satisfaction), improving the health of populations, and reducing the cost of care. The principles of integrative nursing offer clear and specific guidance that can shape and impact patient care in all clinical settings. PMID:25973268

    Traditionally, rule interactions are handled at implementation time through rule task properties that control the order in which rules are executed. By doing so, knowledge about the behavior and interactions of decision rules is not captured at modeling time. We argue that this is important knowledge that should be integrated in the modeling phase. In this project, we build upon current work on a conceptual schema to represent clinical knowledge for decision support in the form of if then rules. This schema currently captures provenance of the clinical content, context where such content is actionable (i.e. constraints) and the logic of the rule itself. For this project, we borrowed concepts from both the Semantic Web (i.e., Ontologies) and Complex Adaptive Systems (CAS), to explore a conceptual approach for modeling rule interactions in an enterprise-wide clinical setting. We expect that a more comprehensive modeling will facilitate knowledge authoring, editing and update; foster consistency in rules implementation and maintenance; and develop authoritative knowledge repositories to promote quality, safety and efficacy of healthcare.

    Indicators of the performance of clinical preventive services (CPS) have been adopted in the ambulatory setting to improve quality of care. The impact of CPS was evaluated in a network of 49 primary care practices providing care to an estimated 245,000 adults in the Dallas–Fort Worth area through a sample chart review to determine delivery of recommended evidence-based CPS combined with medical literature estimates of the effectiveness of CPS. In this population in 2005, CPS were estimated to have prevented 36 deaths and 97 incident cases of cancer; 420 coronary heart disease events (including 66 sudden deaths) and 118 strokes; 816 cases of influenza and pneumonia (including 24 hospital admissions); and 87 osteoporosis-related fractures. Thus, CPS have substantial benefits in preventing deaths and illness episodes. PMID:18628969

    Person-centred care can improve the well-being of patients and is therefore a key driver in healthcare developments in the UK. The current study aims to investigate the complex relationship between cognitive impairment, dependency and well-being in people with a wide range of acquired brain and spinal injuries. Sixty-five participants, with varied acquired brain and spinal injuries, were selected by convenience sampling from six inpatient clinical neuroscience settings. Participants were observed using Dementia Care Mapping - Neurorehabilitation (DCM-NR) and categorised based on severity of cognitive impairment. A significant difference in the behaviours participants engaged in, their well-being and dependency was found between the severe cognitive impairment group and the mild, moderate or no cognitive impairment groups. Dependency and cognitive impairment accounted for 23.9% of the variance in well-ill-being scores and 17.2% of the variance in potential for positive engagement. The current study highlights the impact of severe cognitive impairment and dependency on the behaviours patients engaged in and their well-being. It also affirms the utility of DCM-NR in providing insights into patient experience. Consideration is given to developing DCM-NR as a process that may improve person-centred care in neuroscience settings.

    The principles of 'lean management' have permeated many sectors of today's business world, secondary to the success of the Toyota Production System. This management method enables workers to eliminate mistakes, reduce delays, lower costs, and improve the overall quality of the product or service they deliver. These lean management principles can be applied to health care. Their implementation within the ambulatory care setting is predicated on the continuous identification and elimination of waste within the process. The key concepts of flow time, inventory and throughput are utilized to improve the flow of patients through the clinic, and to identify points that slow this process -- so-called bottlenecks. Nonessential activities are shifted away from bottlenecks (i.e. the physician), and extra work capacity is generated from existing resources, rather than being added. The additional work capacity facilitates a more efficient response to variability, which in turn results in cost savings, more time for the physician to interact with patients, and faster completion of patient visits. Finally, application of the lean management principle of 'just-in-time' management can eliminate excess clinic inventory, better synchronize office supply with patient demand, and reduce costs.

    Objectives: To assess the knowledge and behaviour of researchers regarding criteria for authorship, and the practices of ghost and gift authorship. Design: Semidirective interviews of senior clinical researchers. Setting: University hospital. Participants: Thirty-nine main investigators of clinical research programmes. Main measurements: Awareness and use of International Committee of Medical Journal Editors (ICMJE) criteria for authorship, and perceptions about ghost and gift authorship. Results: A total of 48 protocols submitted by 42 principal investigators between 1994 and 1996 were identified. Thirty-nine investigators were contacted; 37 (one of whom delegated a co-author) were interviewed between May 2002 and March 2003. Two co-authors of two principal investigators were also interviewed. In all, 42 studies were represented. The interviews lasted for 40–90 minutes and were conducted with openness and respect for confidentiality. The choice of names of co-authors did not follow the ICMJE recommendations. Half of the respondents stated they were aware of criteria for authorship and knew of ICMJE, but most of them did not cite any of the ICMJE criteria among those they applied in deciding authorship. Most of them disagreed with the obligation to meet the three criteria justifying co-authorship because they found these too rigid and inapplicable. Gift authorship was a common practice; 59% of the respondents had been a recipient of gift authorship. Twenty-five (64%) were aware of ghost authorship and the majority considered it questionable and blameworthy. Conclusions: The ICMJE criteria were ignored by clinicians at a university hospital. Ghost and gift authorship were frequent among them. There is a need for French guidelines for authorship to be prepared and implemented. PMID:16199598

    Objective To evaluate the potential feasibility of application of the extended International Classification of Functioning, Disability and Health (ICF) Core Set for stroke. Methods We retrospectively reviewed the medical records of 40 stroke outpatients (>6 months after onset) admitted to the Department of Rehabilitation Medicine for comprehensive rehabilitation. Clinical information of the patients were respectively evaluated to link to the 166 second-level categories of the extended ICF Core Set for stroke. Results Clinical information could be linked to 111 different ICF categories, 58 categories of the body functions component, eight categories of the body structures component, 38 categories of the activities and participation component, and seven categories of the environmental factors component. Conclusion The body functions component might be feasible for application of the extended ICF Core Set for stroke to clinical settings. The activities and participation component and environmental factors component may not be directly applied to clinical settings without additional evaluation tools including interview and questionnaire.

    2016-02-01

    Sarcopenia refers to age-associated decrease in muscle mass and function. The condition was originally described in the elderly, but emerging evidence suggests that it is also a concern among the chronically ill nonelderly. Currently there are a number of definitions for diagnosing sarcopenia; however, in the clinical setting, abdominal computed tomography (CT) scans completed for diagnostic purposes can be utilized to identify CT-defined sarcopenia. Recent studies suggest that prevalence of CT-defined sarcopenia is high among chronically ill patients, ranging from 15%-50% in patients with cancer, 30%-45% with liver failure, and 60%-70% for critically ill patients in the intensive care unit. Depleted muscle mass is associated with infectious complications, prolonged duration of mechanical ventilation, longer hospitalization, greater need for rehabilitation care after hospital discharge, and higher mortality. In consideration of the growing population of older adults with multiple comorbidities, more research is needed to identify sarcopenia and develop interventions that are directed at attenuating or reversal muscle loss.

    The objective of this study was to provide what we believe to be the first report of the establishment of a clinical psychology service to provide accessible psychological assessment, intervention and crisis support, integrated within an existing East London sexual health clinical and outreach service for commercial sex workers (CSWs). Data are presented on referral patterns, demographics, presenting issues to clinical psychology, interventions and outcomes for the first year of the service. Women presented with a range of psychosocial needs. Psychological interventions included direct therapy, signposting to other services and consultation with staff. We concluded that this flexible model of service provision improves access to mental health services within the context of a specialist sexual health and outreach service for CSWs. The provision of a named, female clinical psychologist who provides both the clinical sessions and attends outreach has been an important factor in developing trust and familiarity, leading to better uptake of the clinical psychology service.

    Objectives To estimate the cost and patterns of expenditure of dry eye treatment. Methodology We retrieved data on the type and cost of dry eye treatment in Singapore National Eye Centre from pharmacy and clinic inventory databases over a 2 year period (2008–2009) retrospectively. According to the type of treatment, data were sorted into 7 groups; meibomien gland disease (MGD) treatment, preservative free lubricant eye drops, preserved lubricant eye drops, lubricant ointments and gels, cyclosporine eye drops, oral supplements and non-pharmacological treatments/procedures. Each recorded entry was considered as one patient episode (PE). Comparisons in each group between two years were carried out using Pearson Chi-Square test. Significance level was set at alpha  = 0.05. Results Cost data from 54,052 patients were available for analysis. Total number of recorded PEs was 132,758. Total annual expenditure on dry eye treatment for year 2008 and 2009 were US$1,509,372.20 and US$1,520,797.80 respectively. Total expenditure per PE in year 2008 and 2009 were US$22.11 and US$23.59 respectively. From 2008 to 2009, there was a 0.8% increase in total annual expenditure and 6.69% increase in expenditure per PE. Pharmacological treatment attributes to 99.2% of the total expenditure with lubricants accounting for 79.3% of the total pharmacological treatment expenditure. Total number of units purchased in preservative free lubricants, cyclosporine eye drops and MGD therapy have increased significantly (p<0.001) whereas number of units purchased in preserved lubricants and ointments/gels have reduced significantly (p<0.001) from 2008 to 2009. Conclusion Dry Eye imposes a significant direct burden to health care expenditure even without considering indirect costs. Health care planners should be aware that these direct costs appear to increase over the time and more so for particular types of medications. Given the limitations of socio-economic data, true societal costs of Dry

    This article utilizes the case of Ms H. to examine the contrasting ways that surrogate decision makers move from simply hearing information about the patient to actually knowing and understanding the patient's medical condition. The focus of the case is on a family's request to actually see the patient's wounds instead of being told about the wounds, and the role of clinical ethicists in facilitating this request. We argue that clinical ethicists have an important role to play in the work of converting information into knowledge and that this can serve as a valuable way forward in the midst of seemingly intractable conflicts in the medical setting.

    Background Diabetes group clinics can effectively control hypertension, but data to support glycemic control is equivocal. This study evaluated the comparative effectiveness of two diabetes group clinic interventions on glycosolated hemoglobin (HbA1c) levels in primary care. Methods Participants (n = 87) were recruited from a diabetes registry of a single regional VA medical center to participate in an open, randomized comparative effectiveness study. Two primary care based diabetes group interventions of three months duration were compared. Empowering Patients in Care (EPIC) was a clinician-led, patient-centered group clinic consisting of four sessions on setting self-management action plans (diet, exercise, home monitoring, medications, etc.) and communicating about progress with action plans. The comparison intervention consisted of group education sessions with a diabetes educator and dietician followed by an additional visit with one’s primary care provider. HbA1c levels were compared post-intervention and at one-year follow-up. Results Participants in the EPIC intervention had significantly greater improvements in HbA1c levels immediately following the active intervention (8.86 to 8.04 vs. 8.74 to 8.70, mean [SD] between-group difference 0.67±1.3, P=.03) and these differences persisted at 1 year follow-up (.59±1.4, P=.05). A repeated measures analysis using all study time points found a significant time-by-treatment interaction effect on HbA1c levels favoring the EPIC intervention (F(2,85) =3.55, P= .03). The effect of the time-by-treatment interaction appears to be partially mediated by diabetes self-efficacy (F(1,85) =10.39, P= .002). Conclusions Primary care based diabetes group clinics that include structured goal-setting approaches to self-management can significantly improve HbA1c levels post-intervention and maintain improvements for 1-year.

    2014-12-01

    The clinical use of the Diagnostic and Statistical Manual of Mental Disorders (DSM) is explicitly stated as a goal for both the DSM Fourth Edition and DSM Fifth Edition (DSM-5) revisions. Many uses assume a relatively faithful application of the DSM diagnostic definitions. However, studies demonstrate significant discrepancies between clinical psychiatric diagnoses with those made using structured interviews suggesting that clinicians do not systematically apply the diagnostic criteria. The limited information regarding how clinicians actually use the DSM raises important questions: a) How can the clinical use be improved without first having a baseline assessment? b) How can potentially significant shifts in practice patterns based on wording changes be assessed without knowing the extent to which the criteria are used as written? Given the American Psychiatric Association's plans for interim revisions to the DSM-5, the value of a detailed exploration of its actual use in clinical practice remains a significant ongoing concern and deserves further study including a number of survey and in vivo studies.

    The recommendations from the seventh report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7) were compared with those of a recent article by Aram V. Chobanian, Chairman of the JNC 7. The purpose was to identify the changes that this author proposed and determine how they might affect clinical work, as well as the health services and public health implications. The JNC 7 and the article in question coincide on all essential points, except that the article is more flexible when it comes to the use of diuretics at the start of treatment for high blood pressure. Chronic disease management should take place in health systems with primary care approach, where the epidemiology of such diseases and scientific advances in prevention offer an excellent opportunity for redesigning the health services and making them more effective. High blood pressure, as a public health problem, demands health interventions aimed not only at reducing harm but modifying its etiologic determinants. The challenge is to recognize that an integrated approach to clinical medicine, health services, and public health would offer an attractive opportunity to interrupt and prevent the continuous and costly vicious circle that managing high blood pressure and its complications implies.

    "The Pregnancy and Health Profile" (PHP) is a free prenatal genetic screening and clinical decision support (CDS) software tool for prenatal providers. PHP collects family health history (FHH) during intake and provides point-of-care risk assessment for providers and education for patients. This pilot study evaluated patient and provider responses to PHP and effects of using PHP in practice. PHP was implemented in four clinics. Surveys assessed provider confidence and knowledge and patient and provider satisfaction with PHP. Data on the implementation process were obtained through semi-structured interviews with administrators. Quantitative survey data were analyzed using Chi square test, Fisher's exact test, paired t tests, and multivariate logistic regression. Open-ended survey questions and interviews were analyzed using qualitative thematic analysis. Of the 83% (513/618) of patients that provided feedback, 97% felt PHP was easy to use and 98% easy to understand. Thirty percent (21/71) of participating physicians completed both pre- and post-implementation feedback surveys [13 obstetricians (OBs) and 8 family medicine physicians (FPs)]. Confidence in managing genetic risks significantly improved for OBs on 2/6 measures (p values ≤0.001) but not for FPs. Physician knowledge did not significantly change. Providers reported value in added patient engagement and reported mixed feedback about the CDS report. We identified key steps, resources, and staff support required to implement PHP in a clinical setting. To our knowledge, this study is the first to report on the integration of patient-completed, electronically captured and CDS-enabled FHH software into primary prenatal practice. PHP is acceptable to patients and providers. Key to successful implementation in the future will be customization options and interoperability with electronic health records.

    PURPOSE We examine the processes and document the calendar time required to activate Phase II and III clinical trials by an oncology group: the Eastern Cooperative Oncology Group (ECOG). METHODS Setup steps were documented by: 1) interviewing ECOG headquarters and statistical center staff, and committee chairs, 2) reviewing standard operating procedure manuals, and 3) inspecting study records, documents, and emails to identify additional steps. Calendar time was collected for each major process for each study in this set. RESULTS Twenty-eight Phase III studies were activated by ECOG during the 01/2000–07/2006 study period. We examined in detail a sample of 16 of those studies. More than 481 distinct processes were required for study activation: 420 working steps, 61 major decision points, 26 processing loops, and 13 stopping points. Median calendar days to activate a trial in the Phase III subset was 783 days (median, 285 to 1542 days) from executive approval and 808 days (range, 435 to 1604 days) from initial conception of the study. Data were collected for all Phase II and Phase III trials activated and completed during this time period (n=52) for which development time represented 43.9% and 54.1% of the total trial time respectively. CONCLUSION The steps required to develop and activate a clinical trial may require as much or more time than the actual completion of a trial. The data demonstrates that to improve the activation process, research should to be directed toward streamlining both internal and external groups and processes. PMID:18519773

    Interindividual variability in drug response is a major clinical problem. Polymedication and genetic polymorphisms modulating drug-metabolising enzyme activities (cytochromes P450, CYP) are identified sources of variability in drug responses. We present here the relevant data on the clinical impact of the major CYP polymorphisms (CYP2D6, CYP2C19 and CYP2C9) on drug therapy where genotyping and phenotyping may be considered, and the guidelines developed when available. CYP2D6 is responsible for the oxidative metabolism of up to 25% of commonly prescribed drugs such as antidepressants, antipsychotics, opioids, antiarrythmics and tamoxifen. The ultrarapid metaboliser (UM) phenotype is recognised as a cause of therapeutic inefficacy of antidepressant, whereas an increased risk of toxicity has been reported in poor metabolisers (PMs) with several psychotropics (desipramine, venlafaxine, amitriptyline, haloperidol). CYP2D6 polymorphism influences the analgesic response to prodrug opioids (codeine, tramadol and oxycodone). In PMs for CYP2D6, reduced analgesic effects have been observed, whereas in UMs cases of life-threatening toxicity have been reported with tramadol and codeine. CYP2D6 PM phenotype has been associated with an increased risk of toxicity of metoprolol, timolol, carvedilol and propafenone. Although conflicting results have been reported regarding the association between CYP2D6 genotype and tamoxifen effects, CYP2D6 genotyping may be useful in selecting adjuvant hormonal therapy in postmenopausal women. CYP2C19 is responsible for metabolising clopidogrel, proton pump inhibitors (PPIs) and some antidepressants. Carriers of CYP2C19 variant alleles exhibit a reduced capacity to produce the active metabolite of clopidogrel, and are at increased risk of adverse cardiovascular events. For PPIs, it has been shown that the mean intragastric pH values and the Helicobacter pylori eradication rates were higher in carriers of CYP2C19 variant alleles. CYP2C19 is

    A hybrid model combining Monte Carlo method with diffraction theory of wave optics has been developed and applied to quantitatively simulate the in-line diffractive phase-contrast x-ray imaging of three dimensional tissue samples under actual clinic imaging parameters. The primary microcosmic interactions of medical-energy x-ray within matter including photoabsorption, Compton scattering, and coherent scattering, have been taken into account in the Monte Carlo simulation. A diffraction processing based on Fresnel diffraction theory is carried out to simulate the macroscopic diffraction effect. A comparison with experiment results has also been performed.

    Objective The 17-item PCS was designed for priority-setting and queue management of children and adolescents referred for mental health services. Here we assess aspects of the validity of the Children’s Mental Health (CMH) Priority Criteria Score (PCS), developed by the Western Canada Waiting List Project (WCWL). The PCS was evaluated across clinical settings of increasing acuity and in terms of its relationship to two variables reflecting criteria-related validity and actual wait times. Method Intake workers completed PCS forms for 497 referrals enrolled for treatment in three clinical areas over approximately two fiscal years. The completion time of the PCS form was estimated in relation to the total referral and screening process. Intake workers completed the PCS items and did not use the total score at the time of intake and form completion to triage or place clients; hence, the PCS was independent of enrollment and placement within the continuum of care. Furthermore, clinicians in the receiving programs had to accept the triage decisions for the PCS to be used in the study analysis. Results The PCS score was meaningfully related to the measures of criteria-related validity (e.g., clinician perceived urgency, clinician perceived maximum acceptable waiting times) and triage to clinical settings of increasing acuity. There was a significant mean difference in the PCS for those accepted to community, day, or inpatient settings. Conclusions The PCS appears to be a useful, efficient measure of clinical urgency adequate for use in priority-setting for children waiting for mental health services. PMID:18392175

    2007-01-01

    Unethical behavior in both classroom and clinical settings is a concern for nurse educators and has the potential to greatly influence the quality of patient care. A review of the literature suggests that students may view unethical clinical behaviors as different from unethical classroom behaviors because they recognize that clinical behaviors may have a direct effect on patient care. An overview of three moral theories, proposed by Kohlberg, Gilligan, and Rest, provides insight into the reasons for unethical behavior. These theories provide the foundation for strategies nurse educators can use to help reduce unethical behavior in both classroom and clinical settings in an attempt to ensure quality patient care.

    In the past decade, molecular classification of cancer has gained high popularity owing to its high predictive power on clinical outcomes as compared with traditional methods commonly used in clinical practice. In particular, using gene expression profiles, recent studies have successfully identified a number of gene sets for the delineation of cancer subtypes that are associated with distinct prognosis. However, identification of such gene sets remains a laborious task due to the lack of tools with flexibility, integration and ease of use. To reduce the burden, we have developed an R package, CAsubtype, to efficiently identify gene sets predictive of cancer subtypes and clinical outcomes. By integrating more than 13,000 annotated gene sets, CAsubtype provides a comprehensive repertoire of candidates for new cancer subtype identification. For easy data access, CAsubtype further includes the gene expression and clinical data of more than 2000 cancer patients from TCGA. CAsubtype first employs principal component analysis to identify gene sets (from user-provided or package-integrated ones) with robust principal components representing significantly large variation between cancer samples. Based on these principal components, CAsubtype visualizes the sample distribution in low-dimensional space for better understanding of the distinction between samples and classifies samples into subgroups with prevalent clustering algorithms. Finally, CAsubtype performs survival analysis to compare the clinical outcomes between the identified subgroups, assessing their clinical value as potentially novel cancer subtypes. In conclusion, CAsubtype is a flexible and well-integrated tool in the R environment to identify gene sets for cancer subtype identification and clinical outcome prediction. Its simple R commands and comprehensive data sets enable efficient examination of the clinical value of any given gene set, thus facilitating hypothesis generating and testing in biological and

    The instant measurements provided by the Portacount fit-test instrument have been used as the gold standard in predicting the protection of an N95 respirator in a laboratory environment. The conventional Portacount fit-test method, however, cannot deliver real-time measurements of face-seal leakage when the N95 respirator is in use in clinical settings. This research was divided into two stages. Stage 1 involved developing and validating a new quantitative fit-test method called the Personal Respiratory Sampling Test (PRST). In Stage 2, PRST was evaluated in use during nursing activities in clinical settings. Eighty-four participants were divided randomly into four groups and were tested while performing bedside nursing procedures. In Stage 1, a new PRST method was successfully devised and validated. Results of Stage 2 showed that the new PRST method could detect different concentrations and different particle sizes inside the respirator while the wearer performed different nursing activities. This new fit-test method, PRST, can detect face seal leakage of an N95 respirator being worn while the wearer performs clinical activities. Thus, PRST can help ensure that the N95 respirator actually fulfils its function of protecting health-care workers from airborne pathogens.

    Ubiquitous computing requires ubiquitous access to information and knowledge. With the release of openEHR Version 1.0 there is a common model available to solve some of the problems related to accessing information and knowledge by improving semantic interoperability between clinical systems. Considerable work has been undertaken by various bodies to standardise Clinical Data Sets. Notwithstanding their value, several problems remain unsolved with Clinical Data Sets without the use of a common model underpinning them. This paper outlines these problems like incompatible basic data types and overlapping and incompatible definitions of clinical content. A solution to this based on openEHR archetypes is motivated and an approach to transform existing Clinical Data Sets into archetypes is presented. To avoid significant overlaps and unnecessary effort during archetype development, archetype development needs to be coordinated nationwide and beyond and also across the various health professions in a formalized process.

    IN BRIEF This article describes a study to gain insight into the utility and perceived feasibility of the American Diabetes Association's Diabetes Risk Test (DRT) implemented by nurse practitioners (NPs) in the retail clinic setting. The DRT is intended for those without a known risk for diabetes. Researchers invited 1,097 NPs working in the retail clinics of a nationwide company to participate voluntarily in an online questionnaire. Of the 248 NPs who sent in complete responses, 114 (46%) indicated that they used the DRT in the clinic. Overall mean responses from these NPs indicated that they perceive the DRT as a feasible tool in the retail clinic setting. Use of the DRT or similar risk assessment tools in the retail clinic setting can aid in the identification of people at risk for type 2 diabetes.

    Canine parvovirus type 2 (CPV-2) is the main etiological agent of viral enteritis in dogs. Actually in literature, CPV-2 has been reported with clinical signs that vary from the classical disease, and immunochromatography test and PCR technique have been introduced to veterinary hospitals to confirm CPV-2 diagnosis and other infections. However, the reliability of these techniques has been poorly analyzed. In this study, we evaluated the sensitivity and specificity of veterinary clinical diagnosis, immunochromatography test and PCR technique. Our data indicate that variations in the clinical signs of CPV-2 complicate the gathering of an appropriate diagnosis; and immunochromatography test and PCR technique do not have adequate sensitivity to diagnose positive cases.

    Care for low back pain remains a clinical enigma. Its high prevalence and cost to the system warrants attention for improvement. Although, no major recent clinical breakthroughs for resolving back pain have emerged, reducing unnecessary tests, eliminating useless or harmful practices, preventing care dependence, and enhancing coping skills can be useful goals for improving patient outcomes. Quality Improvement (QI) approaches can serve as bridge between clinical intuition and large scale science. Three chiropractic delivery settings including two teaching clinics and one large multidisciplinary spine care center incorporated QI approaches as part of an initiative to improve low back pain care. All clinics were able to implement sustainable process and outcomes improvements.

    Aim: To examine the relationship between sensitivity measured from the BREAST test-set and clinical performance. Background: Although the UK and Australia national breast screening programs have regarded PERFORMS and BREAST test-set strategies as possible methods of estimating readers' clinical efficacy, the relationship between test-set and real life performance results has never been satisfactorily understood. Methods: Forty-one radiologists from BreastScreen New South Wales participated in this study. Each reader interpreted a BREAST test-set which comprised sixty de-identified mammographic examinations sourced from the BreastScreen Digital Imaging Library. Spearman's rank correlation coefficient was used to compare the sensitivity measured from the BREAST test-set with screen readers' clinical audit data. Results: Results shown statistically significant positive moderate correlations between test-set sensitivity and each of the following metrics: rate of invasive cancer per 10 000 reads (r=0.495; p < 0.01); rate of small invasive cancer per 10 000 reads (r=0.546; p < 0.001); detection rate of all invasive cancers and DCIS per 10 000 reads (r=0.444; p < 0.01). Conclusion: Comparison between sensitivity measured from the BREAST test-set and real life detection rate demonstrated statistically significant positive moderate correlations which validated that such test-set strategies can reflect readers' clinical performance and be used as a quality assurance tool. The strength of correlation demonstrated in this study was higher than previously found by others.

    There exist limitations in both commercial and in-house clinical decision support systems (CDSSs) and issues related to the integration of different knowledge sources and CDSSs. We chose Standard-based Shareable Active Guideline Environment (SAGE) as a new architecture with knowledge integration and a centralized knowledge base which includes authoring/management functions and independent CDSS, and applied it to Drug-Drug Interaction (DDI) CDSS. The aim of this study was to evaluate the feasibility of the newly integrated DDI alerting CDSS into a real world hospital information system involving construction of an integrated CDSS derived from two heterogeneous systems and their knowledge sets. The proposed CDSS was successfully implemented and compensated for the weaknesses of the old CDSS from knowledge integration and management, and its applicability in actual situations was verified. Although the DDI CDSS was constructed as an example case, the new CDS architecture might prove applicable to areas of CDSSs.

    Objective: To assess the quality of value sets in clinical quality measures, both individually and as a population of value sets. Materials and methods: The concepts from a given value set are expected to be rooted by one or few ancestor concepts and the value set is expected to contain all the descendants of its root concepts and only these descendants. (1) We assessed the completeness and correctness of individual value sets by comparison to the extension derived from their roots. (2) We assessed the non-redundancy of value sets for the entire population of value sets (within a given code system) using the Jaccard similarity measure. Results: We demonstrated the utility of our approach on some cases of inconsistent value sets and produced a list of 58 potentially duplicate value sets from the current set of clinical quality measures for the 2014 Meaningful Use criteria. Conclusion: These metrics are easy to compute and provide compact indicators of the completeness, correctness, and non-redundancy of value sets. PMID:24551422

    Solutions are employed to support clinical research trial tasks in community-based practice settings. Using the IT Implementation Framework (ITIF), an integrative framework intended to guide the synthesis of theoretical perspectives for planning multi-level interventions to enhance IT use, we sought to understand the barriers and facilitators to clinical research in community-based practice settings preliminary to implementing new informatics solutions for improving clinical research infrastructure. The studies were conducted in practices within the Columbia University Clinical Trials Network. A mixed-method approach, including surveys, interviews, time-motion studies, and observations was used. The data collected, which incorporates predisposing, enabling, and reinforcing factors in IT use, were analyzed according to each phase of ITIF. Themes identified in the first phase of ITIF were 1) processes and tools to support clinical trial research and 2) clinical research peripheral to patient care processes. Not all of the problems under these themes were found to be amenable to IT solutions. Using the multi-level orientation of the ITIF, we set forth strategies beyond IT solutions that can have an impact on reengineering clinical research tasks in practice-based settings. Developing strategies to target enabling and reinforcing factors, which focus on organizational factors, and the motivation of the practice at large to use IT solutions to integrate clinical research tasks with patient care processes, is most challenging. The ITIF should be used to consider both IT and non-IT solutions concurrently for reengineering of clinical research in community-based practice settings.

  1. Vaginal Birth After Caesarean Section in Low Resource Settings: The Clinical and Ethical Dilemma.

    PubMed

    Wanyonyi, Sikolia; Muriithi, Francis G

    2015-10-01

    Vaginal birth after Caesarean section (VBAC) has long been practised in low resource settings using unconventional methods. This not only poses danger to the woman and her baby, but could also have serious legal and ethical implications. The adoption of this practice has been informed by observational studies with many deficiencies; this is so despite other studies from settings in which the standard of care is much better that show that elective repeat Caesarean section (ERCS) may actually be safer than VBAC. This raises questions about whether we should insist on a dangerous practice when there are safer alternatives. We highlight some of the challenges faced in making this decision, and discuss why the fear of ERCS may not be justified after all in low resource settings. Since a reduction in rates of Caesarean section may not be applicable in these regions, because their rates are already low, the emphasis should instead be on adequate birth spacing and safer primary operative delivery.

    The SET protein is a potent inhibitor of protein phosphatase 2A (PP2A). Here, we report the oncogenic role of SET in hepatocarcinogenesis, clinical aggressiveness and anti-hepatocellular carcinoma (HCC) therapeutics. By analyzing samples obtained from 147 HCC patients, we found that SET overexpression was detected specifically in 30.6% HCC tumor samples, and was significantly associated with worse clinical features and high p-Akt expression in HCC tumors. Co-expression of SET and Akt predicted shorter post-operative recurrence-free survival in this cohort (P=0.045). Furthermore, SET was significantly associated with cell growth and hepatosphere formation. To elucidate the anti-HCC potential of targeting SET, we generated a novel SET antagonist, EMQA (N(4)-(3-ethynylphenyl)-6,7-dimethoxy-N(2)-(4-phenoxyphenyl) quinazoline-2,4-diamine). EMQA enhanced PP2A activity via disrupting SET-PP2Ac (catalytic domain of PP2A) binding in HCC cells, which restored PP2A-mediated p-Akt downregulation and promoted HCC cell death. In HCC cells or recombinant proteins expressing the N- and C- truncated forms of SET, only the C-terminal SET was required for EMQA targeting. Furthermore, combining sorafenib and EMQA showed good synergism in inhibiting HCC survival. Our findings suggested the oncogenic role of SET and the adverse prognostic value of SET overexpression in HCC. This alteration defines a subgroup of HCC patients who could benefit from SET antagonists, such as EMQA.

    Modern history of short-term group psychotherapy dates back to the late 1950-ies. From then to present day, this psychotherapeutic method has been used in various forms, from dynamic-oriented to cognitive behavioural psychotherapies. Although it has always been considered rather controversial, due its cost-effectiveness, it has been capturing more and more popularity. This paper presents the specificities of first session short-term psychotherapy psychodrama group through session work with two examined groups: a group of 20 adult women who suffer from mild or moderate forms of unipolar depression and a group of 20 students of the School of Medicine in Zagreb without any psychiatric symptomatology. The results indicate the high importance of having structure in first psychodrama session, of relating it with the previously thoroughly conducted, initial, clinical, interviews, and of the clarity and focus in terms of determining the goals of therapy, especially in a clinical context. This study also confirmed assumptions regarding the need for different approaches of warming-up in psychodrama, both in the clinical and in non-clinical samples. A psychodrama psychotherapist should have good time managing skills and capability to convert the time available into an opportunity for directly boosting the group energy and work on therapeutic alliance.

    Since a large amount of clinical data are being stored electronically, discovery of knowledge from such clinical databases is one of the important growing research area in medical informatics. For this purpose, we develop KDD-R (a system for Knowledge Discovery in Databases using Rough sets), an experimental system for knowledge discovery and machine learning research using variable precision rough sets (VPRS) model, which is an extension of original rough set model. This system works in the following steps. First, it preprocesses databases and translates continuous data into discretized ones. Second, KDD-R checks dependencies between attributes and reduces spurious data. Third, the system computes rules from reduced databases. Finally, fourth, it evaluates decision making. For evaluation, this system is applied to a clinical database of meningoencephalitis, whose computational results show that several new findings are obtained. PMID:8563283

    Handheld or palm-based computing technology, commonly known as personal digital assistants (PDAs), are having a tremendous impact in many personal, educational, and business settings. The potential is particularly compelling for healthcare, specifically in the clinical setting. By exploring the development of the technology, applications, and products, as well as issues regarding its use, a better understanding of this technology can be gained. The rapid acceptance and ongoing swift development of handheld computing technology is leading to an evolution in the way clinical data and information move to and from the bedside and into the patient record. This article focuses on three main areas related to PDAs: the development of the palm technology, its potential in clinical settings, and available specific resources.

    Currently, quality issues concerning clinical research of traditional Chinese medicine (TCM) have come into the spotlight. It has been recognized that poorly-devised research methodology largely restricted the development of clinical research in TCM. The choice of appropriate outcome measurements is key to the success of clinical research; however, the current procedure for outcomes selection in clinical research of TCM is problematic due to the underdevelopment of clinical methodology. Under this circumstance, we propose the introduction to the concept of Core Outcome Set (COS) and discuss the feasibility of developing a COS system that caters for clinical studies in TCM, in the hope that the outcome evaluation system could be up to international standards.

    This article describes a method for creating highly contextual assessments of couples therapy interaction using concepts from Systemic Functional Linguistics (SFL). According to SFL, talk in interaction serves three primary functions: to mediate social relations, to negotiate representations of reality, and to organize and structure the event as coherent. These concepts are operationalized using observational q-methodology. The Clinical Discourse Q-Sets (CDQS) include three separate q-sets for use by trained observers in rating 12-min segments of couples therapy conversation. Each q-set captures one aspect of the communication process as defined by Systemic Functional theory. Good-to-high reliabilities for the q-set profiles over various (n = 16) couples therapy episodes were found. Preliminary evidence for the conceptual structure and clinical validity of the system was found.

    Organizational interventions are being suggested to increase the rate of quality research dissemination and uptake. This article describes how one tertiary institution is using an evidence-based nursing (EBN) committee as an organizational strategy to shift its nursing culture toward clinical scholarship. A number of approaches and activities that have stimulated the movement toward evidence-based practice (EBP) are examined: organizational commitment to EBP, strategic positioning of the EBN committee within nursing's administrative structure, articulation of a mission, conceptualization of a model for EBN practice, learning on the job, selection and adoption of an evidence-based model for implementing change, marketing for a change in culture toward clinical scholarship, and other selected examples of projects undertaken by the committee. Action-oriented principles associated with committee experiences are related to the approaches and activities.

    In this study, the social interactions between students and their teachers in an ambulatory clinic setting were investigated using Bales's interaction process analysis framework. Observational data were collected during five small-group sessions. The observations were quantified, and the behaviors of students and teachers were compared statistically. This study demonstrated that the interaction between students and their teachers was for the most part equal and could be characterized as "positively task oriented." The study has implications for veterinary educators wishing to use social psychology frameworks to assess the quality of learning in small-group clinical setting.

    Background Although support is one of the most substantial needs of nursing students during clinical education, it is not clearly defined in the literature. Objectives The current study aimed to explore the concept of support in clinical settings as perceived by nursing students. Materials and Methods A qualitative content analysis was used to explore the meaning of student support in clinical settings. A purposive sampling with maximum variation was used to select the participants among bachelor nursing students in the nursing school of Babol University of Medical Sciences in the north of Iran. Semi-structured interviews were conducted to gather the perceptions and experiences of seventeen nursing students. Conventional content analysis was applied to analyze the data. Results In the current study, the main theme, nurturance, was emerged with seven subthemes of humanistic behavior with the student, respectful communication with students, accepting the student in the clinical setting, sustaining confidence, need based supervision, accepting the profession in the society and empowerment. Conclusions Nursing students support in the clinical education requires a nurturing care; a care that leads to the sense of worthiness and respectability in students and contributes to the improvement of their clinical abilities.

    2014-06-01

    Pharmacists have developed innovative practices in various settings as singular providers or as members of multidisciplinary or interdisciplinary teams. Examples include pharmacists practicing in heart failure, hypertension, or hyperlipidemia clinics. There is a paucity of literature describing pharmacists in interdisciplinary memory clinics and specifically pharmacists practicing in interdisciplinary, primary care-based memory clinics. New practice models should be disseminated to guide others in the development of similar models given the complexity of this population. Patients with dementia are more difficult to manage because of cognitive impairment, behavioral and psychological symptoms, the common presence of multiple comorbidities, and related polypharmacy and caregiver issues. These challenges require expertise in neurodegenerative disorders and geriatrics. The purpose of this article is to describe the role of clinical pharmacists providing care to patients with cognitive complaints in a primary care-based, interdisciplinary memory clinic, with a focus on how the pharmacist practices and is integrated in this collaborative care setting. Patients are assessed using an interdisciplinary approach, with team consensus for assessment and planning of care. Pharmacists' activities include assessment of (1) appropriateness of medications based on frailty, (2) medications that can impair cognition and/or function, (3) medication adherence and management skills, and (4) vascular risk factor control. Pharmacists provide education regarding medications and diseases, ensure appropriate transitions in care, and conduct home visits. Pharmacist participation in this clinic represents a novel opportunity to advance pharmacy practice in primary care, interdisciplinary models. Work is ongoing to describe outcomes attributable to pharmacist participation in this clinic.

    The availability of clinical datasets and knowledge mining methodologies encourages the researchers to pursue research in extracting knowledge from clinical datasets. Different data mining techniques have been used for mining rules, and mathematical models have been developed to assist the clinician in decision making. The objective of this research is to build a classifier that will predict the presence or absence of a disease by learning from the minimal set of attributes that has been extracted from the clinical dataset. In this work rough set indiscernibility relation method with backpropagation neural network (RS-BPNN) is used. This work has two stages. The first stage is handling of missing values to obtain a smooth data set and selection of appropriate attributes from the clinical dataset by indiscernibility relation method. The second stage is classification using backpropagation neural network on the selected reducts of the dataset. The classifier has been tested with hepatitis, Wisconsin breast cancer, and Statlog heart disease datasets obtained from the University of California at Irvine (UCI) machine learning repository. The accuracy obtained from the proposed method is 97.3%, 98.6%, and 90.4% for hepatitis, breast cancer, and heart disease, respectively. The proposed system provides an effective classification model for clinical datasets. PMID:25821508

    Objectives Use of a rubber dam during root canal treatment is considered the standard of care because it enhances patient safety and optimises the odds of successful treatment. Nonetheless, not all dentists use a rubber dam, creating disconnect between presumed standard of care and what is actually done in clinical practice. Little is known about dentists’ attitudes towards use of the rubber dam in their practices. The objectives were to: (1) quantify these attitudes and (2) test the hypothesis that specific attitudes are significantly associated with rubber dam use. Setting National Dental Practice-Based Research Network (NationalDentalPBRN.org). Participants 1490 network dentists. Outcome measures Dentists completed a questionnaire about their attitudes towards rubber dam use during root canal treatment. Three attitude scales comprised 33 items that used a 5-point ordinal scale to measure beliefs about effectiveness, inconvenience, ease of placement, comparison to other isolation techniques and patient factors. Factor analysis, cluster analysis and multivariable logistic regression analysed the relationship between attitudes and rubber dam use. Results All items had responses at each point on the 5-point scale, with an overall pattern of substantial variation across dentists. Five attitudinal factors (rubber dam effectiveness; inconvenient/time-consuming; ease of placement; effectiveness compared to Isolite; patient factors) and 4 clusters of practitioners were identified. Each factor and cluster was independently and strongly associated with rubber dam use. Conclusions General dentists have substantial variation in attitudes about rubber dam use. Beliefs that rubber dam use is not effective, inconvenient, time-consuming, not easy to place or affected by patient factors, were independently and significantly associated with lower rubber dam use. These attitudes explain why there is substantial discordance between presumed standard of care and actual practice

    Most training programs use learners' subjective ratings of their teachers as the primary measure of teaching effectiveness. In a recent study we found that preclinical medical students' ratings of classroom teachers were associated with perceived charisma and physical attractiveness of the teacher, but not intellect. Here we explored whether the relationship between these variables and teaching effectiveness ratings holds in the clinical setting. We asked 27 Internal Medicine residents to rate teaching effectiveness of ten teachers with whom they had worked on a clinical rotation, in addition to rating each teacher's clinical skills, physical attractiveness, and charisma. We used linear regression to study the association between these explanatory variables and teaching effectiveness ratings. We found no association between rating of physical attractiveness and teaching effectiveness. Clinical skill and charisma were independently associated with rating of teaching effectiveness (regression coefficients [95 % confidence interval] 0.73 [0.60, 0.85], p < 0.001 and 0.12 [0.01, 0.23], p = 0.03, respectively). The variables associated with effectiveness of classroom and clinical teachers differ, suggesting context specificity in teaching effectiveness ratings. Context specificity may be explained by differences in the exposure that learners have to teachers in the classroom versus clinical setting-so that raters in the clinical setting may base ratings upon observed behaviours rather than stereotype data. Alternatively, since subjective ratings of teaching effectiveness inevitably incorporate learners' context-specific needs, the attributes that make a teacher effective in one context may not meet the needs of learners in a different context.

    Transitioning to digital imaging operations in a department of radiology is often difficult for many radiologists, but it is a change that many have made effectively. Transitioning to digital operations in a clinic setting is even more difficult for the referring physician operating a business in the clinic. This paper will discuss our experience with transitioning several off site clinics to digital imaging operations. We will discuss the process followed to identify the physical equipment required to support clinic operations in a digital imaging environment, the process followed to help the physicians adjust their work patterns to allow them to practice in a digital imaging environment, and the benefits and pitfalls of implementing digital imaging in an off site clinic. Four off site clinic locations will be evaluated: 1. cancer clinic located immediately adjacent to the main hospital that relies heavily on CT and MRI images in their practice, 2. small clinic located about 60 miles from the main hospital that acquires xray images on site, 3. larger clinic located about 20 miles from the main hospital that acquires xray, MRI and CT images on site, 4. sports medicine clinic located about 2 miles from the main hospital that acquires xray images on site. Each of these clinics has a very different patient clientele and therefore operates differently in nearly all aspects of their daily operations. The physician's need for and use of film and digital images varies significantly between the sites and therefore each site has presented different challenges to our implementation process. As we explain the decisions that were made for each of these sites and reveal the methods that were used to help the physicians make the transition, the readers should be able to draw information that will be helpful to them as they make their own transition to a digital operation.

    This paper describes an automated medical information management system within a clinic setting. The system includes an optically scanned data entry system (OpScan), a generalized, interactive retrieval and storage software system(Medical Information Management System, MIMS) and the use of time-sharing. The system has the advantages of minimal hardware purchase and maintenance, rapid data entry and retrieval, user-created programs, no need for user knowledge of computer language or technology and is cost effective. The OpScan-MIMS system has been operational for approximately 16 months in a sexually transmitted disease clinic. The system's application to medical audit, quality assurance, clinic management and clinical training are demonstrated.

    2015-01-01

    By the use of extended intelligent information technology tools for fully automated healthcare-associated infection (HAI) surveillance, clinicians can be informed and alerted about the emergence of infection-related conditions in their patients. Moni--a system for monitoring nosocomial infections in intensive care units for adult and neonatal patients--employs knowledge bases that were written with extensive use of fuzzy sets and fuzzy logic, allowing the inherent un-sharpness of clinical terms and the inherent uncertainty of clinical conclusions to be a part of Moni's output. Thus, linguistic as well as propositional uncertainty became a part of Moni, which can now report retrospectively on HAIs according to traditional crisp HAI surveillance definitions, as well as support clinical bedside work by more complex crisp and fuzzy alerts and reminders. This improved approach can bridge the gap between classical retrospective surveillance of HAIs and ongoing prospective clinical-decision-oriented HAI support.

  4. Lung cancer staging: the value of PET depends on the clinical setting

    PubMed Central

    2014-01-01

    Background Although positron emission tomography (PET) imaging is widely recommended in the evaluation of patients with lung cancer, randomized controlled trials (RCTs) assessing this have demonstrated inconsistent results. We asked whether differences in the clinical context and endpoints could explain these discrepancies. Methods We used realist synthesis methods to analyze how contextual differences among RCTs affected the results. We focused on RCTs to minimize confounding yet permit evaluation of differences by comparing across studies. Results This analysis suggests that the impact of PET depends on the clinical setting. PET is of greatest benefit in identifying M1 disease in patients with a high chance of such involvement and when little traditional imaging [e.g., abdominal/pelvis computed tomography (CT) and bone scan] is used. Identification of N2,3 involvement by PET prior to resection is seen primarily when there is at least a moderate probability of such and the rate of invasive staging is high. The rate of N2 disease not identified preoperatively appears to increase if PET is used to avoid invasive mediastinal staging in clinical settings in which the risk of N2,3 involvement is moderately high. There is both a potential benefit in avoiding stage-inappropriate resection as well as a risk of missed (stage-appropriate) resection if PET findings are not evaluated carefully. Conclusions A blanket recommendation for PET may be too simplistic without considering nuances of the clinical setting. PMID:25589964

    Karam, Elie G.; El Khoury, Elaine; Itani, Lynn

    2016-01-01

    Background An essential point in evaluating the utility of measuring temperaments is the stability of the instrument used especially in the presence of mental disorders. One of the most commonly used instruments in the clinical setting is the Temperament Evaluation of Memphis, Pisa, Paris and San Diego Auto-questionnaire (TEMPS-A). To our knowledge, the TEMPS-A’s stability in an outpatient adult clinical setting has not been evaluated. Objective: To assess the stability of the effect of temperament, time and clinical intervention. Methods: A sample of 89 adult outpatients was assessed at baseline and follow-up on their TEMPS-A scores. Diagnoses of mental disorders were reached through clinical interviews, and the severity of the conditions was clinically assessed at baseline and follow-up on a Likert scale. Changes in scores were examined in terms of z-scores, and possible predictors of the change in scores were assessed. Results: Eighty-nine percent of all subjects’ temperaments scores did not change or changed less than one z-score, and specifically: 84.2% in the case of depressive, 89.9% for cyclothymic, 92.1% for hyperthymic, 92.2% for irritable, and 86.5% for anxious temperaments. For all of the five temperaments, age, gender, time difference between baseline and follow up, number of diagnoses, and percent improvement were not significantly associated with the change in temperament scores. Limitations: Well-established severity measures would add to the validity of any future findings. Conclusion: Shifts in temperament scores between baseline and follow-up were minor, thus proving the stability of temperaments and the TEMPS-A scale in a clinical setting. PMID:27733865

    The purpose of this article was to discuss the process of setting up a nuchal translucency (NT) screening clinic in clinical practice, how to interpret the information in combination with other clinical tests, what to do if abnormal results are obtained, and to illustrate some of the fetal anomalies that are associated with an increased NT. The NT was initially implemented to predict the likelihood of a fetus with Down syndrome. Maternal age can be combined with fetal NT and maternal serum biochemistry (free β-hCG and PAPP-A) at 11 to 14 weeks to identify about 90% of affected fetuses. Setting up a clinic to perform the NT screening requires certified physicians and certified sonographers. Certification can be obtained for both physicians and sonographers through Nuchal Translucency Quality Review and Fetal Medicine Foundation. Cell-free DNA testing is now altering what our patients are choosing to evaluate fetuses at risk for chromosomal anomalies and congenital anomalies. Common pitfalls to performing, interpreting, and conveying results of the NT are illustrated in this article. Nasal bone measurement, fetal anatomy examination and fetal echocardiography are tools that add sensitivity to the detection of chromosomal abnormalities. Examples of fetal anomalies discovered during the NT screening are also illustrated. Screening for obstetric complications is an additional benefit to the NT clinic.

    The present study applied item response theory to identify an efficient set of items of the Achenbach Externalizing scale from the Child Behavior Checklist (CBCL; 33 items) and Teacher's Report Form (TRF; 35 items) that were sensitive to clinical-range scores. Mothers and teachers rated children's externalizing problems annually from ages 5 to 13 years in two independent samples (Ns = 585 and 1,199). Item properties for each rater across ages 5–8 and 9–13 were examined with item response theory. We identified 10 mother- and teacher-reported items from both samples based on the items' measurement precision for sub-clinical and clinical levels of externalizing problems: externalizing problems that involve meanness to others, destroying others' things, fighting, lying and cheating, attacking people, screaming, swearing/obscene language, temper tantrums, threatening people, and being loud. Scores on the scales using these items had strong reliability and psychometric properties, capturing nearly as much information as the full Externalizing scale for classifying clinical levels of externalizing problems. Scores on the scale with the 10 CBCL items had moderate accuracy, equivalent to the full Externalizing scale, in classifying diagnoses of conduct disorder based on a research diagnostic interview. Of course, comprehensive clinical assessment would consider additional items, dimensions of behavior, and sources of information, too, but it appears that the behaviors tapped by this select set of items may be core to externalizing psychopathology in children.

    2014-01-01

    Control of walking has been described by a tripartite model consisting of stepping, equilibrium, and adaptability. This review focuses on walking adaptability, which is defined as the ability to modify walking to meet task goals and environmental demands. Walking adaptability is crucial to safe ambulation in the home and community environments and is often severely compromised after a stroke. Yet quantification of walking adaptability after stroke has received relatively little attention in the clinical setting. The objectives of this review were to examine the conceptual challenges for clinical measurement of walking adaptability and summarize the current state of clinical assessment for walking adaptability. We created nine domains of walking adaptability from dimensions of community mobility to address the conceptual challenges in measurement and reviewed performance-based clinical assessments of walking to determine if the assessments measure walking adaptability in these domains. Our literature review suggests the lack of a comprehensive well-tested clinical assessment tool for measuring walking adaptability. Accordingly, recommendations for the development of a comprehensive clinical assessment of walking adaptability after stroke have been presented. Such a clinical assessment will be essential for gauging recovery of walking adaptability with rehabilitation and for motivating novel strategies to enhance recovery of walking adaptability after stroke.

    Patient safety is enhanced when nursing staff recognize and respond to subtle changes in a patient's condition. In this quality improvement project, simulated clinical scenarios were conducted with staff nurses on a multi-specialty surgical unit. Scenarios were developed from actual patient situations as well as from calls to the rapid response team. Nurses were given the opportunity to practice assessment, critical thinking, and communication skills. Pre- and post-project surveys were used to assess nurses' perceived level of confidence and skill in handling emergency situations. Post-project survey data showed that nurses perceived that the scenario exercises improved their confidence and skill in managing critical patient situations. In addition, the findings supported the continued use of the scenarios as a teaching strategy. The scenarios have increased nurses' awareness of early signs of patients' conditions deteriorating and have the potential to decrease the number of patient situations that escalate to emergencies.

    In clinical settings, nursing staff often find themselves responsible for students who have varying time management skills. Nurses need to respond sensitively and appropriately, and to teach nursing students how to prioritize and better allocate time. This is important not only for developing students' clinical skills but also for shaping their perceptions about the quality of the placement and their willingness to consider it as a potential work specialty. In this column, some simple, practical strategies that nurses can use to assist students with improving their time management skills are identified.

    Findlay, Barbara; Verhoef, Marja

    2004-01-01

    Creation of an optimal healing environment (OHE) in a clinical setting is a multifaceted undertaking and subject to a wide variety of developmental influences. While comprehensive definitions for OHE might provide sufficient guidance for communicating philosophy and values and developing patient-practitioner processes, direction for creating a supportive administrative structure or establishing an evaluation/research strategy is less defined. Operationalizing the concept of OHE by breaking it down into components such as values, structure, process, and measurement of outcomes, proved to be a useful framework for analyzing the evolution of our integrated care program. Future OHE initiatives may benefit from using this type of framework to assess readiness among cocreators prior to development and implementation, as a guide for ongoing evaluation of an OHE postimplementation and as a basis for comparing OHEs across a variety of clinical settings.

    The International Society for Stem Cell Research (ISSCR) presents its 2016 Guidelines for Stem Cell Research and Clinical Translation (ISSCR, 2016). The 2016 guidelines reflect the revision and extension of two past sets of guidelines (ISSCR, 2006; ISSCR, 2008) to address new and emerging areas of stem cell discovery and application and evolving ethical, social, and policy challenges. These guidelines provide an integrated set of principles and best practices to drive progress in basic, translational, and clinical research. The guidelines demand rigor, oversight, and transparency in all aspects of practice, providing confidence to practitioners and public alike that stem cell science can proceed efficiently and remain responsive to public and patient interests. Here, we highlight key elements and recommendations in the guidelines and summarize the recommendations and deliberations behind them.

    Purpose The aim of this study was to determine the diagnostic value of three screening questionnaires in identifying Korean patients at high risk for obstructive sleep apnea (OSA) in a sleep clinic setting in Korea. Materials and Methods Data were collected from 592 adult patients with suspected OSA who visited a sleep center. All patients completed the Sleep Apnea of Sleep Disorder Questionnaire (SA-SDQ), the Berlin questionnaire, and the STOP-Bang questionnaire. Estimated OSA risk was compared to a diagnosis of OSA. The sensitivity, specificity, positive predictive value, and negative predictive value were calculated for each questionnaire. Results The prevalence of OSA was 83.6% using an apnea-hypopnea index (AHI) ≥5/h and 58.4% for an AHI ≥15/h. The STOP-Bang questionnaire had a high sensitivity (97% for AHI ≥5/h, 98% for AHI ≥15/h), but the specificity was low (19% and 11%, respectively). In contrast, the sensitivity of the SA-SDQ was not high enough (68% for AHI ≥5/h, 74% for AHI ≥15/h) to be useful in a clinical setting, whereas the specificity was relatively good (66% and 61%, respectively). The sensitivity and specificity values of the Berlin questionnaire fell between those of the STOP-Bang questionnaire and the SA-SDQ. Conclusion The STOP-Bang questionnaire may be useful for screening OSA in a sleep clinic setting, but its specificity is lower than the acceptable level for this purpose. A new screening questionnaire with a high sensitivity and acceptable specificity is therefore needed in a sleep clinic setting. PMID:25837173

    A new set of 174 pictures in black-and-white, coloured and spatially filtered versions, taken from photographs of real objects belonging to different semantic categories, was realised for experimental and clinical research on visual object processing. Two samples, one of English speakers and one of Italian speakers, were tested in order to provide the normative data for each picture, in both black-and-white and coloured versions, in relation to familiarity, visual complexity and name agreement.

    Clinical, epidemiological, and laboratory diagnostic issues of human monocytotropic ehrlichiosis (HME) were investigated in a retrospective case study conducted at a national reference laboratory (Focus Technologies, formerly MRL Reference Laboratory), and at the University of Texas Medical Branch at Galveston, Texas, during 1997 and 1998. Standard questionnaires were sent to physicians for each laboratory-diagnosed patient 2 days to 2 weeks after immunofluorescent antibody assay results were available. Among the 41 cases for which data were obtained, 32 (78%) were definite cases of HME, and 9 (22%) were probable cases of HME. Tick bite or exposure to ticks was recorded in more than 97% of cases. The most prominent clinical findings were fever, abdominal tenderness, and regional lymphadenopathy. There was an association between age and severity of illness. The main laboratory findings included leukopenia, thrombocytopenia, and elevated aspartate aminotransferase and alanine aminotransferase. Clinical and laboratory findings were nonspecific and were not good predictors of the severity of illness. The 90% of patients who received doxycycline treatment underwent rapid clinical improvement with a favorable outcome. The usual duration of effective treatment with doxycycline was 7 to 10 days. This retrospective study is unique because it was based in a commercial reference laboratory setting that receives specimens from different geographic locations. The clinical and laboratory information from 41 patients provides insight into the epidemiological, clinical, and laboratory characteristics of HME. PMID:12965923

    Social changes and new technologies have brought new problems in doctor-patient relationships. In many clinical contexts conscientious objection is misused, with negative effects for patients, healthcare professionals and institutions. The paper aims to clarify what conscientious objection means in a plural society based on a deliberative democracy and to show the different ways of understanding this society in order to respect both the ethical reasons of individuals and the compulsory normative framework of the Rule of Law. Furthermore, the paper identifies some clinical settings where conscientious objection is often invoked by healthcare professionals, and points out and analyses the arguments that explain why this appeal for conscientious objection is neither legitimate nor correct. Finally, it provides examples of the legal basis and Spanish jurisprudence, as well as the relevant clinical and ethical literature on this topic.

    The prescribing clinical health psychologist brings together in one individual a combination of skills to create a hybrid profession that can add value to any healthcare organization. This article addresses the high demand for mental health services and the inequitable distribution of mental health practitioners across the nation. The close link between physical and mental health and evidence that individuals in psychological distress often enter the mental health system via primary care medical clinics is offered as background to a discussion of the author's work as a commissioned officer of the U.S. Public Health Service assigned to the Chaparral Medical Center of La Clinica de Familia, Inc. near the U.S.-Mexico border. The prescribing clinical health psychologist in primary care medical settings is described as a valuable asset to the future of professional psychology.

    The U.S. Veterans Administration (VA) has implemented the clinical nurse leader (CNL) role nationwide. Nursing leaders at the Malcolm Randall VA Medical Center in Gainesville, Florida, implemented the development of the CNL role in the perioperative setting during the summer of 2012. The perioperative department developed the position in partnership with the University of Florida College of Nursing, Gainesville, Florida. The team developed a description of the roles and experiences of the preceptors, the clinical nurse leader resident, and the University of Florida faculty member. The clinical nurse leader resident's successes and the positive outcomes, such as improved patient outcomes, experienced by the perioperative department demonstrated the importance of the CNL role.

    The present study applied item response theory to identify an efficient set of items of the Achenbach Externalizing scale from the Child Behavior Checklist (CBCL; 33 items) and Teacher's Report Form (TRF; 35 items) that were sensitive to clinical-range scores. Mothers and teachers rated children's externalizing problems annually from ages 5 to 13 years in 2 independent samples (Ns = 585 and 1,199). Item properties for each rater across ages 5-8 and 9-13 were examined with item response theory. We identified 10 mother- and teacher-reported items from both samples based on the items' measurement precision for subclinical and clinical levels of externalizing problems: externalizing problems that involve meanness to others, destroying others' things, fighting, lying and cheating, attacking people, screaming, swearing/obscene language, temper tantrums, threatening people, and being loud. Scores on the scales using these items had strong reliability and psychometric properties, capturing nearly as much information as the full Externalizing scale for classifying clinical levels of externalizing problems. Scores on the scale with the 10 CBCL items had moderate accuracy, equivalent to the full Externalizing scale, in classifying diagnoses of conduct disorder based on a research diagnostic interview. Of course, comprehensive clinical assessment would consider additional items, dimensions of behavior, and sources of information, too, but it appears that the behaviors tapped by this select set of items may be core to externalizing psychopathology in children.

    2013-02-01

    Best practice diabetes mellitus clinical treatment and education takes place in the medical clinic, however, patient outcomes are largely mediated through their own behaviour and lifestyle that occurs after they leave the clinical setting. Once they return home, people usually continue to engage in the social, cultural and lifestyle behaviours that had contributed to having diabetes in the first place. Although a host of factors (e.g. economic, health care team and system, condition and client-related) can impact a client's capacity to self-manage, there are client, organizational and community level strategies that may partially mitigate these difficulties. To address client behaviour, clinicians are increasingly becoming skilled to incorporate self-management support including behavioural counselling interventions into routine practice. At the organizational level, the operation and structure of the clinical setting may create difficulty for staff to provide self-management support. Sustaining benefits on a day-to-day basis presents an additional challenge. This article will review several common implementation barriers to self-management support and describe strategies and techniques used elsewhere to successfully integrate self-management support as a core care component for persons with diabetes.

    Aim: The aim of this study is to describe the setting up of a cerebral visual impairment (CVI) clinic in a tertiary care hospital in South India and to describe the spectrum of cases seen. Materials and Methods: The CVI clinic, set up in February 2011, receives interdisciplinary input from a core team involving a pediatrician, neurologist, psychiatrist, occupational therapist, pediatric ophthalmologist, and an optometrist. All children, <18 years of age, with cerebral palsy (CP), learning disability, autism, neurodegenerative diseases, and brain trauma are referred to the clinic for functional vision assessment and opinion for further management. Results: One thousand four hundred and seventy-eight patients were seen in the CVI clinic from February 2011 to September 2015. Eighty-five percent of the patients were from different parts of India. In the clinic, 61% had CP, 28% had seizure disorders, autism was seen in 9.5%, and learning disability, neurodegenerative conditions, and brain injury together constituted 1.5%. Most of the children (45%) had moderate CP. Forty percent of CVI was due to birth asphyxia, but about 20% did not have any known cause for CVI. Seventy percent of patients, who came back for follow-up, were carrying out the habilitation strategies suggested. Conclusions: Average attendance of over 300 new patients a year suggests a definite need for CVI clinics in the country. These children need specialized care to handle their complex needs. Although difficult to coordinate, an interdisciplinary team including the support groups and voluntary organizations is needed to facilitate the successful implementation of such specialized service.

    Background Governments, universities and pan-African research networks are building durable infrastructure and capabilities for biomedical research in Africa. This offers the opportunity to adopt from the outset innovative approaches and technologies that would be challenging to retrofit into fully established research infrastructures such as those regularly found in high-income countries. In this context we piloted the use of a novel mobile digital health platform, designed specifically for low-resource environments, to support high-quality data collection in a clinical research study. Objective Our primary aim was to assess the feasibility of a using a mobile digital platform for clinical trial data collection in a low-resource setting. Secondarily, we sought to explore the potential benefits of such an approach. Methods The investigative site was a research institute in Nairobi, Kenya. We integrated an open-source platform for mobile data collection commonly used in the developing world with an open-source, standard platform for electronic data capture in clinical trials. The integration was developed using common data standards (Clinical Data Interchange Standards Consortium (CDISC) Operational Data Model), maximising the potential to extend the approach to other platforms. The system was deployed in a pharmacokinetic study involving healthy human volunteers. Results The electronic data collection platform successfully supported conduct of the study. Multidisciplinary users reported high levels of satisfaction with the mobile application and highlighted substantial advantages when compared with traditional paper record systems. The new system also demonstrated a potential for expediting data quality review. Discussion and Conclusions This pilot study demonstrated the feasibility of using a mobile digital platform for clinical research data collection in low-resource settings.

    Pure parahydrogen (pH(2) ) is the prerequisite for optimal pH(2) -based hyperpolarization experiments, promising approaches to access the hidden orders of magnitude of MR signals. pH(2) production on-site in medical research centers is vital for the proliferation of these technologies in the life sciences. However, previously suggested designs do not meet our requirements for safety or production performance (flow rate, pressure or enrichment). In this article, we present the safety concept, design and installation of a pH(2) converter, operated in a clinical setting. The apparatus produces a continuous flow of four standard liters per minute of ≈98% enriched pH(2) at a pressure maximum of 50 bar. The entire production cycle, including cleaning and cooling to 25 K, takes less than 5 h, only ≈45 min of which are required for actual pH(2) conversion. A fast and simple quantification procedure is described. The lifetimes of pH(2) in a glass vial and aluminum storage cylinder are measured to be T(1C) (glass vial) =822 ± 29 min and T(1C) (Al cylinder) =129 ± 36 days, thus providing sufficiently long storage intervals and allowing the application of pH(2) on demand. A dependence of line width on pH(2) enrichment is observed. As examples, (1) H hyperpolarization of pyridine and (13) C hyperpolarization of hydroxyethylpropionate are presented.

    Background Clinical relevance of nontuberculous mycobacteria (NTM) is increasing worldwide including in Saudi Arabia. A high species diversity of NTM’s has been noticed in a recent study. However, the identification in diagnostic laboratories is mostly limited to common species. The impact of NTM species diversity on clinical outcome is so far neglected in most of the clinical settings. Methodology/Principal Findings During April 2014 to September 2015, a nationwide collection of suspected NTM clinical isolates with clinical and demographical data were carried out. Primary identification was performed by commercial line probe assays. Isolates identified up to Mycobacterium species level by line probe assays only were included and subjected to sequencing of 16S rRNA, rpoB, hsp65 and 16S-23S ITS region genes. The sequence data were subjected to BLAST analysis in GenBank and Ez-Taxon databases. Male Saudi nationals were dominated in the study population and falling majorly into the 46–59 years age group. Pulmonary cases were 59.3% with a surprising clinical relevance of 75% based on American Thoracic Society guidelines. Among the 40.7% extra-pulmonary cases, 50% of them were skin infections. The identification revealed 16 species and all of them are reporting for the first time in Saudi Arabia. The major species obtained were Mycobacterium monascence (18.5%), M. cosmeticum (11.1%), M. kubicae (11.1%), M. duvalli (7.4%), M.terrae (7.4%) and M. triplex (7.4%). This is the first report on clinical relevance of M. kubicae, M. tusciae, M.yongonense, M. arupense and M.iranicum causing pulmonary disease and M. monascence, M. duvalli, M. perigrinum, M. insubricum, M. holsaticum and M. kyorinense causing various extra-pulmonary diseases in Saudi Arabia. Ascites caused by M. monascence and cecum infection by M. holsaticum were the rarest incidents. Conclusions/Significance To the first time in the country, clinical significance of various rare NTM’s are well explored and

    Previous studies have reported thermal injuries with thick cast materials and warm dip water temperatures, often much higher than is clinically applicable. The goal of this study was to assess the temperature produced in vivo by current casting techniques and materials. The study was done using clinically applicable materials and water temperatures. A single volunteer was used to test skin temperatures produced with various casting techniques. We tested several types of fiberglass and plaster of 5 or 10 layers, used soft roll of 1 or 3 layers, and used dip water temperatures of 30 °C and 40 °C. We tested 2 plaster types: Johnson & Johnson Specialist Fast Set and Specialist Extra Fast Set (New Brunswick, New Jersey). Fiberglass tested included 3M Scotchcast Poly Casting Tape and Scotchcast Plus (St Paul, Minnesota), Royce Medical Techform (Camarrillo, California), and DeBusk Classic Synthetic Tape (Powell, Tennessee). The highest temperature reached using 30 °C water temperature was 39 °C with 10 layers of 3M Scotchcast fiberglass and 1 layer of soft roll. The highest temperature reached with 40 °C water was 39.5 °C, which was reached twice: once with Johnson & Johnson Fast Set Plaster with 5 layers of plaster and 3 layers of soft roll, and once with DeBusk Classic Synthetic Casting Tape of 10 layers with 1 layer of soft roll. Under the clinically applicable conditions described in this study, using the materials we tested and with a normal vascular supply, it is unlikely that temperatures high enough to cause a burn will be produced. We caution that good clinical judgment is advised if a patient reports a cast is too hot.

    Challenging statistical issues often arise in the design and analysis of clinical trials to assess safety and effectiveness of medical devices in the regulatory setting. The use of Bayesian methods in the design and analysis of medical device clinical trials has been increasing significantly in the past decade, not only due to the availability of prior information, but mainly due to the appealing nature of Bayesian clinical trial designs. The Center for Devices and Radiological Health at the Food and Drug Administration (FDA) has gained extensive experience with the use of Bayesian statistical methods and has identified some important issues that need further exploration. In this article, we discuss several topics relating to the use of Bayesian statistical methods in medical device trials, based on our experience and real applications. We illustrate the benefits and challenges of Bayesian approaches when incorporating prior information to evaluate the effectiveness and safety of a medical device. We further present an example of a Bayesian adaptive clinical trial and compare it to a traditional frequentist design. Finally, we discuss the use of Bayesian hierarchical models for multiregional trials and highlight the advantages of the Bayesian approach when specifying clinically relevant study hypotheses.

    2013-01-01

    BACKGROUND: Clinical and epidemiological studies commonly use different case definitions in different settings when investigating work-exacerbated asthma (WEA). These differences are likely to impact characteristics of the resulting WEA cases. OBJECTIVES: To investigate this issue by comparing two groups of WEA cases, one identified using an intensive clinical evaluation and another that fulfilled epidemiological criteria. METHODS: A total of 53 clinical WEA cases had been referred for suspected work-related asthma to two tertiary clinics in Canada, where patients completed tests that confirmed asthma and ruled out asthma caused by work. Forty-seven epidemiological WEA cases were employed asthma patients treated at a health maintenance organization in the United States who completed a questionnaire and spirometry, and fulfilled criteria for WEA based on self-reported, work-related worsening of asthma and relevant workplace exposures as judged by an expert panel. RESULTS: Using different case criteria in different settings resulted in case groups that had a mix of similarities and differences. The clinical WEA cases were more likely to have visited a doctor’s office ≥3 times for asthma in the past year (75% versus 11%; P<0.0001), but did not seek more asthma-related emergency or in-patient care, or have lower spirometry values. The two groups differed substantially according to the industries and occupations where the cases worked. CONCLUSIONS: Findings from both types of studies should be considered when measuring the contribution of work to asthma exacerbations, identifying putative agents, and selecting industries and occupations in which to implement screening and surveillance programs.

    While there are a plethora of in-vivo spectroscopic techniques that have demonstrated the ability to detect a number of diseases in research trials, very few techniques have successfully become a fully realized clinical technology. This is primarily due to the stringent demands on a clinical device for widespread implementation. Some of these demands include: simple operation requiring minimal or no training, safe for in-vivo patient use, no disruption to normal clinic workflow, tracking of system performance, warning for measurement abnormality, and meeting all FDA guidelines for medical use. Previously, our group developed a fiber optic probe-based optical sensing technique known as low-coherence enhanced backscattering spectroscopy (LEBS) to quantify tissue ultrastructure in-vivo. Now we have developed this technique for the application of prescreening patients for colonoscopy in a primary care (PC) clinical setting. To meet the stringent requirements for a viable medical device used in a PC clinical setting, we developed several novel components including an automated calibration tool, optical contact sensor for signal acquisition, and a contamination sensor to identify measurements which have been affected by debris. The end result is a state-of-the-art medical device that can be realistically used by a PC physician to assess a person's risk for harboring colorectal precancerous lesions. The pilot study of this system shows great promise with excellent stability and accuracy in identifying high-risk patients. While this system has been designed and optimized for our specific application, the system and design concepts are universal to most in-vivo fiber optic based spectroscopic techniques.

Gerry Dolan provided an introduction to the symposium by describing what is meant by real-world data (RWD), stressing the role RWD can play in optimising patient outcomes in haemophilia and highlighting the responsibility of all stakeholders to collaborate in continuous data collection. Kristian Juusola (Oulu University Hospital, Oulu, Finland) then provided personal experience as a haemophilia nurse around patient views on adherence to treatment regimes, and how collecting insights into real-world use of treatment can shape approaches to improving adherence. The importance of elucidating pharmacokinetic parameters in a real-world setting was then explored by Vuokko Jokela (Helsinki University, Helsinki, Finland). Finally, Alfonso Iorio (McMaster University, Hamilton, Ontario, Canada) highlighted the importance of quality data collection in translating clinical reality into scientific advances.

    2001-01-01

    Mouse embryonic stem cells have been shown to differentiate into a variety of tissues in vitro and in transplantation experiments can produce many different cell types. Multipotent stem cells in adult humans have also shown a high degree of plasticity: haemopoietic stem cells, for example, have been shown to contribute to several other tissues, such as liver. From these simple observations there has been considerable extrapolation into the use of such putative totipotent stem cells in the clinical setting, with the development of 'designer' tissue engineering, whose aim is to create large tissues or even whole organs for clinical use. In practical terms, however, there are many limitations and difficulties and clinical use has been restricted to a very few settings, eg the use of fetal cells in Parkinson's disease. Nonetheless, there is enormous potential in this area, and also in the application of embryonic or adult stem cells as carriers for gene therapy; but the limitations of such treatment, in particular the stability of manipulated cells, and the problems of ageing and Ooncogenicity, not to mention a host of ethical and regulatory issues, all need to be considered.

    Knowledge of the signalling pathways involved in various diseases has enabled advances in the understanding of pathophysiological, diagnostic and therapeutic models of several inflammatory and autoimmune diseases. Systemic lupus erythematosus is a widely studied autoimmune disease that can affect multiple organs, with a major impact on morbidity and mortality when it involves the kidneys. Over the past 10 years, interest in the role of the TWEAK/Fn14 signalling pathway in lupus nephritis, as well as other clinical settings, has increased. By reviewing the literature, this article assesses the role of this pathway in lupus nephritis, underlines the importance of TWEAK in urine (uTWEAK) as a biomarker of the disease and stresses the favourable results published in the literature from the inhibition of the TWEAK/Fn14 pathway as a therapeutic target in experimental animal models, demonstrating its potential application in other settings. Results of ongoing clinical trials and future research will give us a better understanding of the real benefit of blocking this pathway in the clinical course of several conditions.

    Background: Creativity and innovation are key elements for organization improvement, particularly in nursing, and for finding alternatives for solving nurses’ occupational problems. Nurses’ creativity is affected by motivation. Although, there are many possible sources of motivation, the Iranian nurses’ creativity is seldom clarified, and the most important factors motivating nurses to be creative in clinical settings has rarely been addressed. Objectives: The aim of this study was to explore Iranian nurses’ experiences regarding the most important factors that motivate their creativity in clinical settings. Methods: This qualitative study was conducted using conventional content analysis approach. A purposive sample of sixteen nurses was recruited from two educational hospitals affiliated to Tehran and Jahrom Universities of Medical Sciences in Iran. Data were gathered through conducting face-to-face semi-structured interviews and were analyzed by qualitative content analysis approach. Findings: Five main themes emerged from the data analysis, including: (a) Intrinsic motivators, (b) Extrinsic motivators, (c) Achievement motivators, (d) Relational or altruistic motivators, and (e) Spiritual motivators. Conclusions: Study findings indicated that nurses are creative and innovative individuals. So nurse managers and health policy makers should consider creativity as an integral part of all health and clinical strategies and policies. They should support creative and innovative efforts of nurses and provide a climate in which nurses engage in more creative and productive behaviors. PMID:26156918

    The increasing threat to global health posed by antibiotic resistance remains of serious concern. Human health remains at higher risk due to several reported therapeutic failures to many life threatening drug resistant microbial infections. The resultant effects have been prolonged hospital stay, higher cost of alternative therapy, increased mortality, etc. This opinionated review considers the two main concerns in integrated human health risk assessment (i.e., residual antibiotics and antibiotic resistant genes) in various compartments of human environment, as well as clinical dynamics associated with the development and transfer of antibiotic resistance (AR). Contributions of quorum sensing, biofilms, enzyme production, and small colony variants in bacteria, among other factors in soil, water, animal farm and clinical settings were also considered. Every potential factor in environmental and clinical settings that brings about AR needs to be identified for the summative effects in overall resistance. There is a need to embrace coordinated multi-locational approaches and interrelationships to track the emergence of resistance in different niches in soil and water versus the hospital environment. The further integration with advocacy, legislation, enforcement, technological innovations and further research input and recourse to WHO guidelines on antibiotic policy would be advantageous towards addressing the emergence of antibiotic resistant superbugs.

    Noncognitive neuropsychiatric symptoms (NPS) of dementia (aggression, agitation, depression, anxiety, delusions, hallucinations, apathy, disinhibition) affect individuals with dementia nearly universally across dementia stages and etiologies. NPS are associated with poor outcomes for individuals with dementia and caregivers, including excess morbidity and mortality, greater healthcare use, and earlier nursing home placement, as well as caregiver stress, depression, and difficulty with employment. Although the Food and Drug Administration has not approved pharmacotherapy for NPS, psychotropic medications are frequently used to manage these symptoms, but in the few cases of proven pharmacological efficacy, significant risk of adverse effects may offset benefits. There is evidence of efficacy and limited potential for adverse effects of nonpharmacological treatments, typically considered first line, but their uptake as preferred treatments remains inadequate in real-world clinical settings. Thus, the field currently finds itself in a predicament in terms of management of these difficult symptoms. It was in this context that the University of Michigan Program for Positive Aging, working in collaboration with the Johns Hopkins Alzheimer's Disease Research Center and Center for Innovative Care in Aging sponsored and convened a multidisciplinary expert panel in Detroit, Michigan, in fall 2011 with three objectives: to define critical elements of care for NPS in dementia; to construct an approach describing the sequential and iterative steps of managing NPS in real-world clinical settings that can be used as a basis for integrating nonpharmacological and pharmacological approaches; and to discuss how the approach generated could be implemented in research and clinical care.

    Comprehensive geriatric assessment (CGA) is a multidisciplinary diagnostic and treatment process that identifies medical, psychosocial, and functional capabilities of older adults to develop a coordinated plan to maximize overall health with aging. Specific criteria used by CGA programs to evaluate patients include age, medical comorbidities, psychosocial problems, previous or predicted high healthcare utilization, change in living situation, and specific geriatric conditions. However, no universal criteria have been agreed upon to readily identify patients who are likely to benefit from CGA. Evidence from randomized controlled trials and large systematic reviews and meta-analyses suggested that the healthcare setting may modify the effectiveness of CGA programs. Home CGA programs and CGA performed in the hospital were shown to be consistently beneficial for several health outcomes. In contrast, the data are conflicting for posthospital discharge CGA programs, outpatient CGA consultation, and CGA-based inpatient geriatric consultation services. The effectiveness of CGA programs may be modified also by particular settings or specific clinical conditions, with tailored CGA programs in older frail patients evaluated for preoperative assessment, admitted or discharged from emergency departments and orthogeriatric units or with cancer and cognitive impairment. CGA is capable of effectively exploring multiple domains in older age, being the multidimensional and multidisciplinary tool of choice to determine the clinical profile, the pathologic risk and the residual skills as well as the short- and long-term prognosis to facilitate the clinical decision making on the personalized care plan of older persons.

    The emergency department (ED) serves as the entry point into the U.S. health care system for many patients with limited English proficiency (LEP). This paper reviews the literature on language interpreter utilization in the ED setting. We focused on three clinical issues related to professional language interpretation: (1) patient satisfaction, (2) health care delivery, and (3) current interpreter utilization practices. Compared with-English speaking patients, LEP patients report less satisfaction with medical encounters, have different rates of diagnostic testing, and receive less explanation and follow-up. Although professional interpretation has been associated with improvements in patient satisfaction, communication, and health care access, these services are largely under-utilized in ED settings. Reliance on untrained ad hoc interpreters, perceived time and labor associated with obtaining and working with an interpreter, and costs of implementing professional interpreter services serve as barriers to implementation and utilization.

    Drug abuse is often seen as a unitary phenomenon, partly as a result of the discovery over the past three decades of shared mechanisms of action for addictive substances. Yet the pattern of drug taking is often very different from drug to drug. This is particularly evident in the case of 'club drugs', such as ketamine. Although the number of ketamine abusers is relatively small in the general population, it is quite substantial in some settings. In particular, ketamine abuse is almost exclusively limited to clubs and large music parties, which suggests a major role of context in modulating the reward effects of this drug. This review focuses on recent preclinical and clinical findings, including previously unpublished data, that provide evidence that, even under controlled conditions, ketamine reward is a function of the setting of drug taking.

    Chromosomal microarray analysis (CMA) is a technology used for the detection of clinically-significant microdeietions or duplications, with a high sensitivity for submicroscopic aberrations. It is able to detect changes as small as 5-10Kb in size - a resolution up to 1000 times higher than that of conventional karyotyping. CMA is used for uncovering copy number variants (CNVs) thought to play an important role in the pathogenesis of a variety of disorders, primarily neurodevelopmental disorders and congenital anomalies. CMA may be applied in the prenatal or postnatal setting, with unique benefits and limitations in each setting. The growing use of CMA makes it essential for practicing physicians to understand the principles of this technology and be aware of its powers and limitations.

    Improvement in clinic efficiency in the ambulatory setting is often looked at as an area for development of lean management strategies to deliver a higher quality of healthcare while reducing errors, costs, and delays. To examine the benefits of improving team communication and its impact on clinic flow and efficiency, we describe a time-motion study performed in an academic outpatient Ophthalmology clinic and its objective and subjective results. Compared to clinic encounters without the use of the portable radios, objective data demonstrated an overall significant decreases in mean workup time (15.18 vs. 13.10), room wait (13.10 vs. 10.47), and decreased the total time needed with an MD per encounter (9.45 vs. 6.63). Subjectively, significant improvements were seen in careprovider scores for patient flow (60.78 vs. 84.29), getting assistance (61.89 vs. 88.57), moving patient charts (54.44 vs. 85.71), teamwork (69.56 vs. 91.0), communications (62.33 vs. 90.43), providing quality patient care (76.22 vs. 89.57), and receiving input on the ability to see walk-in patients (80.11 vs. 90.43). For academic purposes, an improvement in engagement in patient care and learning opportunities was noted by the clinic resident-in-training during the pilot study. Portable radios in our pilot study were preferred over the previous method of communication and demonstrates significant improvements in certain areas of clinical efficiency, subjective perception of teamwork and communications, and academic learning.

    Clinical supervision should be a proactive and considered endeavor, not a reactive one. To that end, supervisors should choose supervision processes that are driven by theory, best available research, and clinical experience. These processes should be aimed at helping trainees develop as clinicians. We highlight 3 supervision processes we believe should be used at each supervision meeting: agenda setting, encouraging trainee problem-solving, and formative feedback. Although these are primarily cognitive-behavioral skills, they can be helpful in combination with other supervision models. We provide example dialogue from supervision exchanges, and discuss theoretical and research support for these processes. Using these processes not only encourages trainee development but also models for them how to use the same processes and approaches with clients.

  1. An easy and reliable automated method to estimate oxidative stress in the clinical setting.

    2008-01-01

    During the last few years, reliable and simple tests have been proposed to estimate oxidative stress in vivo. Many of them can be easily adapted to automated analyzers, permitting the simultaneous processing of a large number of samples in a greatly reduced time, avoiding manual sample and reagent handling, and reducing variability sources. In this chapter, description of protocols for the estimation of reactive oxygen metabolites and the antioxidant capacity (respectively the d-ROMs and OXY Adsorbent Test, Diacron, Grosseto, Italy) by using the clinical chemistry analyzer SYNCHRON, CX 9 PRO (Beckman Coulter, Brea, CA, USA) is reported as an example of such an automated procedure that can be applied in the clinical setting. Furthermore, a calculation to compute a global oxidative stress index (Oxidative-INDEX), reflecting both oxidative and antioxidant counterparts, and, therefore, a potentially more powerful parameter, is also described.

    Summary Awake surgery requires coordinated teamwork and communication between the surgeon and the anesthesiologist, as he monitors the patient, the neuroradiologist as he interprets the images for intraoperative confirmation, and the neuropsychologist and neurophysiologist as they evaluate in real-time the patient’s responses to commands and questions. To improve comparison across published studies on clinical assessment and operative settings in awake surgery, we reviewed the literature, focusing on methodological differences and aims. In complex, interdisciplinary medical care, such differences can affect the outcome and the cost-benefit ratio of the treatment. Standardization of intraoperative mapping and related controversies will be discussed in Part II. PMID:24139657

    Due to the rapid expansion of first-line antiretroviral therapy in resource-limited settings (RLS), increasing numbers of people are living with HIV for prolonged periods of time. Treatment programs must now decide how to balance monitoring costs necessary to maximize health benefits for those already on treatment with the continued demand to initiate more patients on first-line treatment. We review currently available evidence related to monitoring strategies in RLS and discuss their implications on timing of switching to second-line treatment, development of HIV resistance, and clinical outcome.

    Background This article describes the development of a virtual glaucoma clinic, whereby technicians collect information for remote review by a consultant specialist. Design and Methods This was a hospital-based service evaluation study. Patients suitable for the stable monitoring service (SMS) were low-risk patients with “suspect”, “early”-to-“moderate” glaucoma who were deemed stable by their consultant care team. Three technicians and one health care assistant ran the service. Patients underwent tests in a streamlined manner in a dedicated clinical facility, with virtual review of data by a consultant specialist through an electronic patient record. Main outcome measure Feasibility of developing a novel service within a UK National Health Service setting and improvement of patient journey time within the service were studied. Results Challenges to implementation of virtual clinic include staffing issues and use of information technology. Patient journey time within the SMS averaged 51 minutes, compared with 92 minutes in the glaucoma outpatient department. Patient satisfaction with the new service was high. Conclusion Implementing innovation into existing services of the National Health Service is challenging. However, the virtual clinic showed an improved patient journey time compared with that experienced within the general glaucoma outpatient department. There exists a discrepancy between patient management decisions of reviewers, suggesting that some may be more risk averse than others when managing patients seen within this model. Future work will assess the ability to detect progression of disease in this model compared with the general outpatient model of care. PMID:26508830

    A Good Clinical Practices (GCPs) course, based on the combination of theoretical modules with a practical training in real-life conditions, was held in 2010 in Burkina Faso. It was attended by 15 trainees from nine African, Asian, and Latin American countries. There were some discrepancies between the average good results at the end of the theoretical phase and the GCP application during the first days of the practical phase, underlying the difficulties of translating theoretical knowledge into good practices. Most of the findings were not unexpected and reflected the challenges commonly faced by clinical investigators in resource-poor contexts (i.e., the high workload at peripheral health facilities, the need to conciliate routine clinical activities with clinical research, and the risk of creating a double standard among patients attending the same health facility [free care for recruited patients versus user fees for non-recruited patients with the same medical condition]). Even if limited in number and time, these observations suggest that a theoretical training alone may not be sufficient to prepare trainees for the challenges of medical research in real-life settings. Conversely, when a practical phase immediately follows a theoretical one, trainees can immediately experience what the research methodology implicates in terms of work organization and relationship with recruited and non-recruited patients. This initial experience shows the complexity of translating GCP into practice and suggests the need to rethink the current conception of GCP training.

    Genetic risk prediction of chronic conditions including obesity, diabetes and CVD currently has limited predictive power but its potential to engage healthy behaviour change has been of immense research interest. We aimed to understand whether the latter is indeed true by conducting a systematic review and meta-analysis investigating whether genetic risk communication affects motivation and actual behaviour change towards preventative lifestyle modification. We included all randomised controlled trials (RCT) since 2003 investigating the impact of genetic risk communication on health behaviour to prevent cardiometabolic disease, without restrictions on age, duration of intervention or language. We conducted random-effects meta-analyses for perceived motivation for behaviour change and clinical changes (weight loss) and a narrative analysis for other outcomes. Within the thirteen studies reviewed, five were vignette studies (hypothetical RCT) and seven were clinical RCT. There was no consistent effect of genetic risk on actual motivation for weight loss, perceived motivation for dietary change (control v. genetic risk group standardised mean difference (smd) -0·15; 95 % CI -1·03, 0·73, P=0·74) or actual change in dietary behaviour. Similar results were observed for actual weight loss (control v. high genetic risk SMD 0·29 kg; 95 % CI -0·74, 1·31, P=0·58). This review found no clear or consistent evidence that genetic risk communication alone either raises motivation or translates into actual change in dietary intake or physical activity to reduce the risk of cardiometabolic disorders in adults. Of thirteen studies, eight were at high or unclear risk of bias. Additional larger-scale, high-quality clinical RCT are warranted.

    Purpose The purpose of this paper is to assess the relationship between patient satisfaction and a variety of clinical quality measures in an ambulatory setting to determine if there is significant overlap between patient satisfaction and clinical quality or if they are separate domains of overall physician quality. Assessing this relationship will help to determine whether there is congruence between different types of clinical quality performance and patient satisfaction and therefore provide insight to appropriate financial structures for physicians. Design/methodology/approach Ordered probit regression analysis is conducted with overall rating of physician from patient satisfaction responses to the Clinician and Groups Consumer Assessment of Healthcare Providers and Systems survey as the dependent variable. Physician clinical quality is measured across five composite groups based on 26 Healthcare Effectiveness Data and Information Set (HEDIS) measures aggregated from patient electronic health records. Physician and patient demographic variables are also included in the model. Findings Better physician performance on HEDIS measures are correlated with increases in patient satisfaction for three composite measures: antibiotics, generics, and vaccination; it has no relationship for chronic conditions and is correlated with decrease in patient satisfaction for preventative measures, although the negative relationship for preventative measures is not robust in sensitivity analysis. In addition, younger physicians and male physicians have higher satisfaction scores even with the HEDIS quality measures in the regression. Research limitations/implications There are four primary limitations to this study. First, the data for the study come from a single hospital provider organization. Second, the survey response rate for the satisfaction measure is low. Third, the physician clinical quality measure is the percent of the physician's relevant patient population that met

    In the early 80s, the word automation was used in the clinical laboratory setting referring only to analyzers. But in late 80s and afterwards, automation found its way into all aspects of the diagnostic process, embracing not only the analytical but also the pre- and post-analytical phase. While laboratories in the eastern world, mainly Japan, paved the way for laboratory automation, US and European laboratories soon realized the benefits and were quick to follow. Clearly, automation and robotics will be a key survival tool in a very competitive and cost-concious healthcare market. What sets automation technology apart from so many other efficiency solutions are the dramatic savings that it brings to the clinical laboratory. Further standardization will assure the success of this revolutionary new technology. One of the main difficulties laboratory managers and personnel must deal with when studying solutions to reengineer a laboratory is familiarizing themselves with the multidisciplinary and technical terminology of this new and exciting field. The present review/glossary aims at giving an overview of the most frequently used terms within the scope of laboratory automation and to put laboratory automation on a sounder linguistic basis.

    Health data has long been scrutinised in relation to data quality and integrity problems. Currently, no internationally accepted or "gold standard" method exists measuring data quality and error rates within datasets. We conducted a source data verification (SDV) audit on a prospective clinical trial dataset. An audit plan was applied to conduct 100% manual verification checks on a 10% random sample of participant files. A quality assurance rule was developed, whereby if >5% of data variables were incorrect a second 10% random sample would be extracted from the trial data set. Error was coded: correct, incorrect (valid or invalid), not recorded or not entered. Audit-1 had a total error of 33% and audit-2 36%. The physiological section was the only audit section to have <5% error. Data not recorded to case report forms had the greatest impact on error calculations. A significant association (p=0.00) was found between audit-1 and audit-2 and whether or not data was deemed correct or incorrect. Our study developed a straightforward method to perform a SDV audit. An audit rule was identified and error coding was implemented. Findings demonstrate that monitoring data quality by a SDV audit can identify data quality and integrity issues within clinical research settings allowing quality improvement to be made. The authors suggest this approach be implemented for future research.

    Unintended pregnancies account for about half of all pregnancies in the United States and, in 1995, numbered nearly 3 million pregnancies. They pose appreciable medical, emotional, social and financial costs on women, their families and society. The US is not attaining national goals to decrease unintended pregnancies, and little is known about effective means for reducing unintended pregnancy rates in adults or adolescents.To examine the evidence about the effectiveness, benefits and harms of counseling in a clinical setting to prevent unintended pregnancy in adults and adolescents and to use the evidence to propose a research agenda.We identified English-language articles from comprehensive searches of the MEDLINE, CINAHL, PsychLit and other databases from 1985 through May 2000; the main clinical search terms included pregnancy (mistimed, unintended, unplanned, unwanted), family planning, contraceptive behavior, counseling, sex counseling, and knowledge, attitudes and behavior. We also used published systematic reviews, hand searching of relevant articles, the second Guide to Clinical Preventive Services and extensive peer review to identify important articles not otherwise found and to assure completeness. Of 673 abstracts examined, we retained 354 for full article review; of these, we used 74 for the systematic evidence review and abstracted data from 13 articles for evidence tables. Four studies addressed the effectiveness of counseling in a clinical setting in changing knowledge, skills and attitudes about contraception and pregnancy; all had poor internal validity and generalizability and collectively did not provide definitive guidance about effective counseling strategies. Nine studies (three in teenage populations) addressed the relationship of knowledge on contraceptive use and adherence. Knowledge of correct contraceptive methods may be positively associated with appropriate use, but reservations about the method itself, partner support of the method

    Background Since September 2005 the International Committee of Medical Journal Editors has required that trials be registered in accordance with the World Health Organization (WHO) minimum dataset, in order to be considered for publication. The objective is to evaluate registries' and individual trial records' compliance with the 2006 version of the WHO minimum data set. Methods A retrospective evaluation of 21 online clinical trial registries (international, national, specialty, pharmaceutical industry and local) from April 2005 to February 2007 and a cross-sectional evaluation of a stratified random sample of 610 trial records from the 21 registries. Results Among 11 registries that provided guidelines for registration, the median compliance with the WHO criteria were 14 out of 20 items (range 6 to 20). In the period April 2005–February 2007, six registries increased their compliance by six data items, on average. None of the local registry websites published guidelines on the trial data items required for registration. Slightly more than half (330/610; 54.1%, 95% CI 50.1% – 58.1%) of trial records completed the contact details criteria while 29.7% (181/610, 95% CI 26.1% – 33.5%) completed the key clinical and methodological data fields. Conclusion While the launch of the WHO minimum data set seemed to positively influence registries with better standardisation of approaches, individual registry entries are largely incomplete. Initiatives to ensure quality assurance of registries and trial data should be encouraged. Peer reviewers and editors should scrutinise clinical trial registration records to ensure consistency with WHO's core content requirements when considering trial-related publications. PMID:19624821

    Clinical features of 40 lymphoproliferative neoplasm patients in the setting of systemic autoimmune diseases managed in the Clinic of Hematology during 1994-2006 were analyzed retrospectively. The classification of systemic autoimmune disease patients was as follows: 15 systemic lupus erythematosus--SLE, 11 rheumatoid arthritis--RA, 12 Sjögren's syndrome--SS, 1 scleroderma, and 1 dermatomyositis. Patients comprised 31 women and 9 men of mean age 55 years (range 33-76). Systemic autoimmune diseases preceeded the development of lymphoproliferative neoplasms in 37/40 (92.5%) patients. Mean latency period between the onset of systemic autoimmune diseases and lymphoproliferative neoplasms occurrence was significantly longer in RA (113 months) than in SLE (75 months) and SS patients (65 months)--P < 0.05. The most frequent lymphoproliferative neoplasms were non-Hodgkin's lymphoma--NHL (35/40; 88%), diffuse large B-cell lymphoma (DBCL)--12 (34%), follicular lymphoma (FC)--7 (20%), small lymphocytic (SL), and marginal zone lymphoma (MZL)--5 (14%) each. The primary site of NHL was extranodal in 18/35 (51.5%) cases. Advanced disease on diagnosis (III + IV clinical stages), constitutional symptoms, and bulky disease were diagnosed in 27/35 (77%), 26/35 (74%), and 3/35 (8.5%) patients, respectively. The overall survival (OS) was as follows (months): DBCL-12, FC-63, SLL-60, and MZL-48. There was no association between the lymphoproliferative neoplasm histological subtype and the systemic autoimmune diseases type or antirheumatic treatment P > 0.05. Our findings are in line with earlier reports showing a high proportion of patients with advanced disease, constitutional symptoms, extranodal manifestations, high grade histology, and low OS in the systemic autoimmune diseases setting.

    New emerging data suggest that bisphosphonates may exert antitumor properties. Preclinical studies have demonstrated that zoledronic acid (ZA) can induce direct and indirect antitumor activities such as inhibition of angiogenesis, invasion and adhesion of tumor cells, and overall tumor progression, stimulation of adoptive and innate immunity and emerging evidence suggests that the use of these agents may prevent the development of skeletal and extra skeletal metastases. This review will critically describe the new growing evidence of antitumor activity exerted by bisphosphonates in cancer patients, both in metastatic disease and in the adjuvant setting. The effects of bisphosphonates on survival in metastatic cancer patients will be described and evidence from retrospective analyses and prospective studies will be critically reported. The early evidence from prospective analyses of survival impact by ZA in the adjuvant setting in breast cancer will be discussed together with the recently published results of the ABCSG-12 study. A new "era" for bisphosphonates in the oncological setting is opening. The clinical data that will be reported in this review represent the first step in a path that will conduct us to explore new horizons in the field of adjuvant and metastatic cancer therapies.

    Many recommended best practices exist for clinical and community diabetes management and prevention. However, in many cases, these recommendations are not being fully utilized. It is useful to gain a sense of currently utilized and needed practices when beginning a partnership building effort to ameliorate such practice problems. The purpose of this study was to assess current practices in clinical settings within the Brazos Valley in preparation for beginning a community-based participatory research project on improving diabetes prevention and management in this region. Fifty-seven physicians with admission privileges to a regional health system were faxed a survey related to current diabetes patient loads, knowledge and implementation of diabetes-related best practices, and related topics. Both qualitative and quantitative examination of the data was conducted. Fifteen percent of responding providers indicated they implemented diabetes prevention best practices, with significant differences between primary-care physicians and specialists. Respondents indicated a need for educational and counseling resources, as well as an increased health-care workforce in the region. The utilization of a faxed-based survey proved an effective means for assessing baseline data as well as serving as a catalyst for further discussion around coalition development. Results indicated a strong need for both clinical and community-based services regarding diabetes prevention and management, and provided information and insight to begin focused community dialogue around diabetes prevention and management needs across the region. Other sites seeking to begin similar projects may benefit from a similar process.

    Studies of the attitudes of medical personnel regarding computer-based clinical consultation systems have shown that successful programs must be designed not only to satisfy a need for expert level advice but also to fit smoothly into the dally routine of physician/users. Planning for system use should accordingly be emphasized in all aspects of the system design. ONCOCIN is an oncology protocol management system that assists physicians with the management of outpatients enrolled in experimental cancer chemotherapy protocols. ONCOCIN was designed for initial implementation in the Stanford Oncology Day Care Center, where it has been in limited use since May of 1981. The clinic's physicians currently use the system dally in the management of patients with Hodgkin's and non-Hodgkin's lymphoma. This work has allowed us to study physician-computer interaction and to explore artificial intelligence research issues. This paper discusses the practical issues to consider when designing a consultation system for physicians and the logistical issues to address when integrating such a system into a clinic setting. We describe how ONCOCIN has addressed these issues, the problems encountered, their resolution, and the lessons learned.

    The Shriners Hospitals for Children-Canada has developed an innovative Interprofessional Education Program to help tomorrow's healthcare professionals gain the skills and knowledge they need to work effectively in teams to provide efficient, collaborative and family-centred care. Undergraduate students in nursing, physiotherapy and occupational therapy participated in group discussions, seminars by staff members and group presentations. Students reported increased understanding of their own and others' roles and a more holistic view of patients and families, and demonstrated their ability to work in teams to create collaborative care plans. Facilitating factors were a strong existing interprofessional team, administrative buy-in and support, consistent clinical nurse specialist involvement and strong, enthusiastic students. Challenges included logistics, time taken away from students' regular clinical time, time required of staff for program planning and implementation, and the difficulty of evaluating effects on patient care. The program shows promise as a way of introducing students to interprofessional practice and giving them a chance to practise their newly acquired skills in a clinical setting. It also has the potential to enhance staff awareness of interprofessional issues and facilitate staff development.

    Task based repetitive therapy has been proposed to help stroke survivors to regain functional control of arm movement. We developed a wearable exoskeleton rehabilitation robot with associated control algorithm and safety protection mechanisms, and a graphic user interface that is easy to use and intuitive to patients and therapists, as the framework for automated and customizable robot-assisted rehabilitation system for clinic and home based therapy. The system was tested in two feasibility studies. The first study involved 6 patients to receive therapeutic training during three time weekly clinic visits for 4 weeks. The second study set up the robot-assisted rehabilitation system at patient's house, where the therapeutic training was practiced on a daily base. Two patients were recruited for the home application study. Patients' performances were assessed using clinical evaluation tools, including Wolf Motor Function Test and Fugl Meyer Assessment (FMA), both before and after the training. The performances of patients during the training weeks were also objectively evaluated by using the robot sensory data.

    Indications for cochlear implants are determined by audiological and medical considerations. Clinical imaging is therefore an integral element for anatomical evaluation in terms of medical considerations. Several authors have discussed the variability of cochlear shape, especially cochlear length. Cochlear length is, however, an increasingly recognized parameter in terms of preoperative evaluation. This study introduces a methodology to determine individual cochlear length in clinical setting by using Cone Beam Computed Tomography. Cochlear length determination was performed retrospectively with an OsiriX curved 3D Multiplanar Reconstruction tool on subjects who underwent temporal bone imaging from January 2011 to February 2013. Cochlear length was defined as the spiral route from the center-distal point of the bony round window along the lateral wall towards the helicotrema, which is the endpoint of the measurement. Cochlear length was measured in 436 temporal bones (218 left ears, 218 right ears, 218 subjects). The mean cochlear length was 37.6 mm (SD: ± 1.93 mm), median was 37.6 mm, range 32-43.5 mm. The cochlear length had a normal distribution. A significant difference was found between cochlear length by gender (p < .0001), but not between the left and right cochlea (p = .301) or according to age. Consideration of the cochlear length in clinical data may be an insufficiently represented parameter in cochlear implant treatment. Literature shows the impact of electrode insertion depth on residual hearing preservation and speech performance. Individual evaluation of the cochlear implant electrode choice may be the next step in personalized cochlear implant treatment as a valuable addition to existing audiological and surgical evaluation.

    Objective: To examine the learning styles of undergraduate athletic training students to determine their consistency in traditional classroom versus clinical settings. Design and Setting: Subjects completed the Learning Styles Inventory twice, once focusing on learning new information in the classroom and the other focusing on learning new information in the clinical setting. The order of focus regarding setting (classroom or clinical) was counterbalanced across subjects. Subjects: A total of 26 undergraduate athletic training students from a Committee on the Accreditation of Allied Health Education Programs accredited athletic training education program (16 women and 10 men; mean age, 24.42 ± 6.44 years) who were currently assigned to a clinical practicum as part of their academic program served as subjects. Measurements: I performed 4 paired t tests, 1 for each learning mode, to determine if differences existed between the classroom and clinical settings. The percentage of respondents whose learning styles changed across settings was also calculated. Results: The paired t tests revealed a significant difference between the Reflective Observation and Active Experimentation modes across settings. In addition, 58% of respondents' learning styles changed according to setting focus. Conclusions: It appears that learning styles do indeed shift, depending on the domain through which an individual is learning. Consequently, teaching strategies incorporated in 1 setting may not be equally effective in the other setting. Each learning setting should, therefore, be treated separately in order to accommodate individual learning styles and maximize learning achievement. Furthermore, if learning styles are to be considered when designing athletic training education, these findings indicate that in order to ensure the validity of the resulting learning style profile, it may be necessary to provide the respondent with a specific focus, either that of a classroom or clinical

    Despite the rising number of new HIV infections among youth, few tailored interventions for youth living with HIV (YLH) have been developed and rigorously tested. Developing tailored interventions necessitates identifying different profiles of YLH and understanding how risk and protective factors cluster together. Obtaining this critical information requires accessing a sufficiently large sample of YLH from diverse geographic settings such as those available through the Adolescent Trials Network for HIV Interventions (ATN). We recruited a cross-sectional sample of 1,712 YLH from ATN clinics; participants completed a survey on psychosocial and health factors. Using latent class analysis on nine composite variables representing risk factors, we identified five classes distinguished by substance use, sexual behavior, and pregnancy history and differing on health outcomes. Findings suggest a need for tailored interventions addressing multiple risky behaviors of HIV-infected youth and research to clarify how intervention effectiveness may differ by risk profile.

    The objective of this paper is to present a brief description of technical solutions for health information system security threats caused by inadequate security and privacy practices in healthcare professionals. A literature search was carried out in ScienceDirect, ACM Digital Library and IEEE Digital Library to find papers reporting technical solutions for certain security problems in information systems used in clinical settings. A total of 17 technical solutions were identified: measures for password security, the secure use of e-mail, the Internet, portable storage devices, printers and screens. Although technical safeguards are essential to the security of healthcare organization's information systems, good training, awareness programs and adopting a proper information security policy are particularly important to prevent insiders from causing security incidents.

    Effective standardization of clinical processes, which is a growing priority for healthcare provider organizations and networks, requires effective teamwork among clinicians and staff from multidisciplinary backgrounds--often from geographically dispersed facilities--to reach consensus on care practices. Yet, most healthcare provider organizations have no precedence or tools for managing large-scale, sustained, collaborative activities. This presentation explores the human and social implications of technology. It specifically addresses healthcare collaboration and describes how innovative collaboration management technologies can be used in the healthcare industry to accelerate care standardization, order set standardization and other initiatives necessary for successful computerized provider order entry and electronic health record deployments. These topics are explored through presentation of a survey of healthcare executives and a case study of an advanced collaboration application that was adapted and deployed in a partnership between a large healthcare provider organization and a commercial developer of document management and collaboration management technologies.

    Rule discovery methods have been introduced to find useful and unexpected patterns from databases. However, one of the most important problems on these methods is that extracted rules have only positive knowledge, which do not include negative information that medical experts need to confirm whether a patient will suffer from symptoms caused by drug side-effect. This paper first discusses the characteristics of medical reasoning and defines positive and negative rules based on rough set model. Then, algorithms for induction of positive and negative rules are introduced. Then, the proposed method was evaluated on clinical databases, the experimental results of which shows several interesting patterns were discovered, such as a rule describing a relation between urticaria caused by antibiotics and food.

    For the past few decades, there has been intense debate in bioethics about the standard of care that should be provided in clinical trials conducted in developing countries. Some interpret the Declaration of Helsinki to mean that control groups should receive the best intervention available worldwide, while others interpret this and other international guidelines to mean the best local standard of care. Questions of justice are particularly relevant where limited resources mean that the local standard of care is no care at all. Introducing human rights law into this complex and longstanding debate adds a new and important perspective. Through non-derogable rights, including the core obligations of the right to health, human rights law can help set a minimum standard of care.

    Wernicke's encephalopathy is an acute neuropsychiatric syndrome resulting from thiamine deficiency, which is associated with significant morbidity and mortality. According to autopsy-based studies, the disorder is still greatly underdiagnosed in both adults and children. In this review, we provide an update on the factors and clinical settings that predispose to Wernicke's encephalopathy, and discuss the most recent insights into epidemiology, pathophysiology, genetics, diagnosis, and treatment. To facilitate the diagnosis, we classify the common and rare symptoms at presentation and the late-stage symptoms. We emphasise the optimum dose of parenteral thiamine required for prophylaxis and treatment of Wernicke's encephalopathy and prevention of Korsakoff's syndrome associated with alcohol misuse. A systematic approach helps to ensure that patients receive a prompt diagnosis and adequate treatment.

    Purpose To estimate the prevalence of off-label and unlicensed prescribing during 2008 at a major paediatric teaching hospital in Western Australia. Methods A 12-month retrospective study was conducted at Princess Margaret Hospital using medication chart records randomly selected from 145,550 patient encounters from the Emergency Department, Inpatient Wards and Outpatient Clinics. Patient and prescribing data were collected. Drugs were classified as off-label or unlicensed based on Australian registration data. A hierarchical system of age, indication, route of administration and dosage was used. Drugs were classified according to the Anatomical Therapeutic Chemical Code. Results A total of 1,037 paediatric patients were selected where 2,654 prescriptions for 330 different drugs were prescribed to 699 patients (67.4%). Most off-label drugs (n = 295; 43.3%) were from the nervous system; a majority of unlicensed drugs were systemic hormonal preparations excluding sex hormones (n = 22, 32.4%). Inpatients were prescribed more off-label drugs than outpatients or Emergency Department patients (p < 0.0001). Most off-label prescribing occurred in infants and children (31.7% and 35.9% respectively) and the highest percentage of unlicensed prescribing (7.2%) occurred in infants (p < 0.0001). There were 25.7% of off-label and 2.6% of unlicensed medications prescribed across all three settings. Common reasons for off-label prescribing were dosage (47.4%) and age (43.2%). Conclusion This study confirmed off-label and unlicensed use of drugs remains common. Further, that prevalence of both is influenced by the clinical setting, which has implications in regards to medication misadventure, and the need to have systems in place to minimise medication errors. Further, there remains a need for changes in the regulatory system in Australia to ensure that manufacturers incorporate, as it becomes available, evidence regarding efficacy and safety of their drugs in children in the

    2016-01-01

    Objective: Review the clinical skills needed to recognize, diagnose, and manage binge-eating disorder (BED) in a primary care setting. Data Sources: A PubMed search of English-language publications (January 1, 2008–December 11, 2014) was conducted using the term binge-eating disorder. Relevant articles known to the authors were also included. Study Selection/Data Extraction: Publications focusing on preclinical topics (eg, characterization of receptors and neurotransmitter systems) without discussing clinical relevance were excluded. A total of 101 publications were included in this review. Results: Although BED is the most prevalent eating disorder, it is underdiagnosed and undertreated. BED can be associated with medical (eg, type 2 diabetes and metabolic syndrome) and psychiatric (eg, depression and anxiety) comorbidities that, if left untreated, can impair quality of life and functionality. Primary care physicians may find diagnosing and treating BED challenging because of insufficient knowledge of its new diagnostic criteria and available treatment options. Furthermore, individuals with BED may be reluctant to seek treatment because of shame, embarrassment, and a lack of awareness of the disorder. Several short assessment tools are available to screen for BED in primary care settings. Pharmacotherapy and psychotherapy should focus on reducing binge-eating behavior, thereby reducing medical and psychiatric complications. Conclusions: Overcoming primary care physician– and patient-related barriers is critical to accurately diagnose and appropriately treat BED. Primary care physicians should take an active role in the initial recognition and assessment of suspected BED based on case-finding indicators (eg, eating habits and being overweight), the initial treatment selection, and the long-term follow-up of patients who meet DSM-5 BED diagnostic criteria.

    Clinical trials designed for survival probability estimation of different treatment policies for chronic diseases like cancer, leukemia, and schizophrenia usually need randomization of treatments in two stages. Since complete remission is rare for these diseases, initially an induction therapy is given for patient's remission. Further treatment, which is often an expensive maintenance therapy, is administered only for the patients with remission. If the maintenance therapy is so expensive that the cost of the trial inflates, only a simple random sample of patients will be treated with the expensive maintenance due to budget constraint. In this article, we have implemented a design using ranked sets instead of simple randomization in the second stage and obtained an unbiased estimator of the overall survival distribution for a particular treatment combination. Through simulation studies under different conditions, we have found that the design we developed based on ranked sets gives an unbiased estimate of the population survival probability which is more efficient than the estimate obtained by the usual design.

    By November 2013, a total of 125 clinical practice guidelines (CPGs) have been developed in Korea. However, despite the high burden of diseases and the clinical importance of CPGs, most chronic diseases do not have available CPGs. Merely 83 CPGs are related to chronic diseases, and only 40 guidelines had been developed in the last 5 yr. Considering the rate of the production of new evidence in medicine and the worsening burden from chronic diseases, the need for developing CPGs for more chronic diseases is becoming increasingly pressing. Since 2011, the Korean Academy of Medical Sciences and the Korea Centers for Disease Control and Prevention have been jointly developing CPGs for chronic diseases. However, priorities have to be set and resources need to be allocated within the constraint of a limited funding. This study identifies the chronic diseases that should be prioritized for the development of CPGs in Korea. Through an objective assessment by using the analytic hierarchy process and a subjective assessment with a survey of expert opinion, high priorities were placed on ischemic heart disease, cerebrovascular diseases, Alzheimer's disease and other dementias, osteoarthritis, neck pain, chronic kidney disease, and cirrhosis of the liver.

    Gene therapy using viral vectors that stably integrate into ex vivo cultured cells holds great promises for the treatment of monogenic diseases as well as cancer. However, carry-over of infectious vector particles has been described to occur upon ex vivo transduction of target cells. This, in turn, may lead to inadvertent spreading of viral particles to off-target cells in vivo, raising concerns for potential adverse effects, such as toxicity of ectopic transgene expression, immunogenicity from in vivo transduced antigen-presenting cells and, possibly, gene transfer to germline cells. Here, we have investigated factors influencing the extent of lentiviral vector (LV) shedding upon ex vivo transduction of human hematopoietic stem and progenitor cells. Our results indicate that, although vector carry-over is detectable when using laboratory-grade vector stocks, the use of clinical-grade vector stocks strongly decreases the extent of inadvertent transduction of secondary targets, likely because of the higher degree of purification. These data provide supportive evidence for the safe use of the LV platform in clinical settings.

    Sonodynamic therapy (SDT) is a form of ultrasound therapy in which specialized chemotherapeutic agents known as sonosensitizers are administered to increase the efficacy of ultrasound-mediated preferential damage of neoplastic cells. Multiple in vitro and in vivo studies have indicated that SDT has the ability to exhibit profound physical and chemical changes on cellular structure. As supportive as the data have been, assessment of this method at the clinical level has been limited to only solid tumors. Although SDT has shown efficacy against multiple adherent neoplastic cell lines, it has also shown particular promise with leukemia-derived cell lines. Potential procedures to administer SDT to leukemia patients are heating the appendages as ultrasound is applied to these areas (Heat and Treat), using an ultrasound probe to scan the body for malignant growths (Target and Destroy), and extracorporeal blood sonication (EBS) through dialysis. Each method offers a unique set of benefits and concerns that will need to be evaluated in preclinical mammalian models of malignancy before clinical examination can be considered. PMID:26380110

    Royal Decree 1093/2010 (3 September 2010) establishes the minimum data set that the clinical reports of discharges and outpatient visits elaborated in the facilities of the National Health System should contain, among others. Until then, the Ministerial Order 221/1984, that only required the drawing up of a discharge report for patients seen in a hospital-regime health care establishment, was in force. In spite of the importance of these documents, their quality is far from that desired, especially that of the reports on visits, which, among other things, are not performed in a high percentage of the cases. Recently the Sociedad Española de Medicina Interna (SEMI) (Spanish Society of Internal Medicine), in collaboration with other scientific societies, issued some recommendations for the drawing up of the discharge reports. In this present work, a series of thoughts are made on the implications of the new decree, especially in the case of the reports of the outpatient clinics.

    Antibacterial strategies to eradicate superbugs from hospitals/nursing homes have had limited success, suggesting the need for employing innovative preventative measures and better understanding of the prevalence of microbial pathogens in close proximity of susceptible populations. A total of 120 environmental samples were collected from the Aga Khan University hospital. Amoebae were identified using morphological characteristics as well as PCR using genus-specific primers, while bacteria were identified using standard biochemical testing. Out of 120 samples tested, 52 (43.3 %) samples were positive for Acanthamoeba, while all 120 (100 %) samples were positive for bacteria. Following bacterial identification, samples showed mixed bacterial populations. Out of 120 samples, 76 (63.3 %) samples were positive for Bacillus spp., 64 (53.3 %) samples were positive for Corynebacterium spp., 32 (26.6 %) samples were positive for Staphylococcus spp., and 9 (7.5 %) samples were positive for Micrococcus spp. The antibiotic susceptibility showed that all bacterial isolates recovered were multiple drug-resistant. The current findings suggest that Acanthamoeba and bacteria coexist in a clinical environment. Given that Acanthamoeba can harbor bacteria, anti-amoebic approaches may represent a strategy in eradicating "superbugs" from the clinical setting in addition to the current measures.

    Because human immunodeficiency virus (HIV)-infected patients receive prophylaxis with oxidative drugs, those with glucose-6-phosphate dehydrogenase (G6PD) deficiency may experience hemolysis. However, G6PD deficiency has not been studied in the Dominican Republic, where many individuals have African ancestry. Our objective was to determine the prevalence of G6PD deficiency in Dominican HIV-infected patients and to attempt to develop a cost-effective algorithm for identifying such individuals. To this end, histories, chart reviews, and G6PD testing were performed for 238 consecutive HIV-infected adult clinic patients. The overall prevalence of G6PD deficiency (8.8%) was similar in males (9.3%) and females (8.5%), and higher in Haitians (18%) than Dominicans (6.4%; P = 0.01). By logistic regression, three clinical variables predicted G6PD status: maternal country of birth (P = 0.01) and a history of hemolysis (P = 0.01) or severe anemia (P = 0.03). Using these criteria, an algorithm was developed, in which a patient subset was identified that would benefit most from G6PD screening, yielding a sensitivity of 94.7% and a specificity of 97.2%, increasing the pretest probability (8.8–15.1%), and halving the number of patients needing testing. This algorithm may provide a cost-effective strategy for improving care in resource-limited settings. PMID:26240158

    When the safety of the public is at stake, it is particularly relevant for licensing and credentialing exam agencies to use defensible standard setting methods to categorize candidates into competence categories (e.g., pass/fail). The aim of this study was to gather evidence to support change to the Comprehensive Osteopathic Medical Licensing-USA Level 2-Performance Evaluation standard setting design and administrative process. Twenty-two video recordings of candidates assessed for clinical competence were randomly selected from the 2014-2015 Humanistic domain test score distribution ranging from the highest to lowest quintile of performance. Nineteen panelists convened at the same site to receive training and practice prior to generating judgments of qualified or not qualified performance to each of the twenty videos. At the end of training, one panel remained onsite to complete their judgments and the second panel was released and given 1 week to observe the same twenty videos and complete their judgments offsite. The two one-sided test procedure established equivalence between panel group means at the 0.05 confidence level, controlling for rater errors within each panel group. From a practical cost-effective and administrative resource perspective, results from this study suggest it is possible to diverge from typical panel groups, who are sequestered the entire time onsite, to larger numbers of panelists who can make their judgments offsite with little impact on judged samples of qualified performance. Standard setting designs having panelists train together and then allowing those to provide judgments yields equivalent ratings and, ultimately, similar cut scores.

    Objective: Body dysmorphic disorder (BDD) is a relatively common psychiatric disorder characterized by preoccupations with perceived defects in physical appearance. This review aimed to explore epidemiology, clinical features, comorbidities, and treatment options for BDD in different clinical settings. Data Source and Study Selection: A search of the literature from 1970 to 2011 was performed using the MEDLINE search engine. English-language articles, with no restriction regarding the type of articles, were identified using the search terms body dysmorphic disorder, body dysmorphic disorder clinical settings, body dysmorphic disorder treatment, and body dysmorphic disorder & psychodermatology. Results: BDD occurs in 0.7% to 2.4% of community samples and 13% of psychiatric inpatients. Etiology is multifactorial, with recent findings indicating deficits in visual information processing. There is considerable overlap between BDD and obsessive-compulsive disorder (OCD) in symptom etiology and response to treatment, which has led to suggestions that BDD can be classified with anxiety disorders and OCD. A recent finding indicated genetic overlap between BDD and OCD. Over 60% of patients with BDD had a lifetime anxiety disorder, and 38% had social phobia, which tends to predate the onset of BDD. Studies reported a high level of comorbidity with depression and social phobia occurring in > 70% of patients with BDD. Individuals with BDD present frequently to dermatologists (about 9%–14% of dermatologic patients have BDD). BDD co-occurs with pathological skin picking in 26%–45% of cases. BDD currently has 2 variants: delusional and nondelusional, and both variants respond similarly to serotonin reuptake inhibitors (SRIs), which may have effect on obsessive thoughts and rituals. Cognitive-behavioral therapy has the best established treatment results. Conclusions: A considerable overlap exists between BDD and other psychiatric disorders such as OCD, anxiety, and delusional

    In May 2011, the Japanese Society of Psychiatry and Neurology released their Guidelines on Conflict of Interest (COI) in Clinical Research and detailed regulations. These guidelines cover clinical research, although each committee of the society may have a policy to cover basic research as well as clinical research. The COI Committee implemented the guidelines, including a one-year trial period. According to the guidelines, members of the society have to disclose their COIs at the time of presentations, manuscript submissions, and publications; the board and committees members have to submit their COIs to the president of the society. During the trial period, the latter was limited to the four committees involved in the development of the guidelines: Conflict of Interest; Pharmaceutical Affairs; Research Ethics; and Editorial Committees. The COI Committee reviewed the COIs submitted by the board and committee members. The COI Committee found that, among the 382 board and committee members, 298 were without COI; 31 COIs were regarded by one committee member as not necessary to be circulated to all the attending members (total of these 2 categories: 329, 87%); 31 COIs (8%) were regarded as necessary to be circulated; and 18 cases (4.7%) were problematic: not submitted or explicit rejection of submission. Considering the seriousness of scientific misconduct by a researcher in another disease area who resigned his professorship and is now under investigation, we should further discuss the implementation of our COI guidelines.

    2016-01-01

    Background: Palliative care in low and middle-income countries is a new discipline, responding to a greater patient need, than in high-income countries. By its very nature, palliative as a specialty has to network with other specialties to provide quality care to patients. For any medical discipline to grow as a specialty, it should be well established in the teaching medical institutions of that country. Data show that palliative care is more likely to establish and grow in an academic health care institution. It is a necessity that multiple networking strategies are adopted to reach this goal. Objectives: (1) To describe a strategic approach to palliative care service development and integration into clinical academic setting. (2) To present the change in metrics to evaluate progress. Design and Setting: This is a descriptive study wherein, the different strategies that are adopted by the Department of Palliative Medicine for networking in an academic health care institution and outside the institution are scrutinized. Measurement: The impact of this networking was assessed, one, at the level of academics and the other, at the level of service. The number of people who attended various training programs conducted by the department and the number of patients who availed palliative care service over the years were assessed. Results: Ten different strategies were identified that helped with networking of palliative care in the institution. During this time, the referrals to the department increased both for malignant diseases (52–395) and nonmalignant diseases (5–353) from 2000 to 2013. The academic sessions conducted by the department for undergraduates also saw an increase in the number of hours from 6 to 12, apart from the increase in a number of courses conducted by the department for doctors and nurses. Conclusion: Networking is an essential strategy for the establishment of a relatively new medical discipline like palliative care in a developing and

    Nuclear medicine imaging provides valuable functional information that complements information obtained with anatomic imaging techniques in the evaluation of patients with specific acute clinical manifestations. Nuclear medicine studies are most often used in conjunction with other imaging modalities and as a problem-solving tool. Under certain circumstances a nuclear medicine study may be indicated as the first-line imaging modality, as in the case of renal scintigraphy for transplant dysfunction in the early postoperative period. Nuclear imaging may be preferred when a conventional first-line study is contraindicated or when it is important to minimize radiation exposure. The portability of nuclear imaging offers particular advantages for the evaluation of critically ill patients whose clinical condition is unstable and who cannot be safely transported out of the intensive care unit. The ability to visualize physiologic and pathophysiologic processes over relatively long time periods without adding to the patient's radiation exposure contributes to the high diagnostic sensitivity of several types of nuclear medicine studies. Viewing the acquired images in the cine mode adds to the value of these studies for diagnosing and characterizing dynamic abnormalities such as intermittent internal bleeding and bile or urine leakage. In this pictorial review, the spectrum of nuclear medicine studies commonly performed in the acute care setting is reviewed according to body systems and organs, with detailed descriptions of the indications, technical considerations, findings, and potential pitfalls of each type of study.

    Objective The aims of this study were to describe the experiences of senior students using mobile devices in a clinical setting while learning and interacting with clinical teachers, patients and each other, and to identify challenges that facilitated or impeded the use of such devices in the hospital. Design Interpretative phenomenology was chosen to guide our enquiry. Semi-structured interviews were conducted to examine the experiences of five senior medical students using mobile devices in the clinical setting. Setting and participants Senior medical students at an international medical school in the Middle East. Results Three main themes emerged from the data analysis: learning; professional identity and transitioning from student to doctor. The findings showed that using mobile devices in the clinical area as a learning tool was not a formalised process. Rather, it was opportunistic learning at the bedside and on occasion a source of distraction from clinical teaching. Students needed to negotiate relationships between themselves, the clinical teacher and patients in order to ensure that they maintained an acceptable professional image. Participants experienced and negotiated the change from student to doctor making them mindful of using their devices at the bedside. Conclusions Mobile devices are part of daily life for a medical student and there is a need to adapt medical education in the clinical setting, to allow the students to use their devices in a sensitive manner.

    Education providers globally use various models for undergraduate nurse clinical education. This paper presents the major findings of a research project conducted by a rural university in Australia that aimed to explore the Clinical Facilitation Model of undergraduate nursing education from a rural perspective. In particular how the Clinical Facilitators enacted their role within the rural environment and to identify any barriers to the provision of effective clinical learning during facilitated clinical experience within this context. This qualitative study used a phenomenological approach to explore the experiences of Clinical Facilitators. Individual in-depth interviews were conducted with eight Clinical Facilitators. Data was analysed using thematic analysis and several themes emerged from the study. This paper will report two of the major findings which are based on how Clinical Facilitators enacted their role within the rural environment. Whilst this study has a rural focus the findings will add to the limited body of knowledge internationally regarding the Clinical Facilitation model used as a result of balancing educational needs of the student with the care needs of the patients in the current health policy climate. The findings will be useful for informing undergraduate curricula, and will assist faculty and health services in planning and implementation of models of clinical education that meet the needs of the student and that are specific to the rural environment. In addition, the findings will provide insight into strategies that the rural Clinical Facilitator can utilise to assist in fulfilling their teaching role.

    The detective quantum efficiency (DQE) is widely accepted as a primary measure of x-ray detector performance in the scientific community. A standard method for measuring the DQE, based on IEC 62220-1, requires the system to have a linear response meaning that the detector output signals are proportional to the incident x-ray exposure. However, many systems have a non-linear response due to characteristics of the detector, or post processing of the detector signals, that cannot be disabled and may involve unknown algorithms considered proprietary by the manufacturer. For these reasons, the DQE has not been considered as a practical candidate for routine quality assurance testing in a clinical setting. In this article we described a method that can be used to measure the DQE of both linear and non-linear systems that employ only linear image processing algorithms. The method was validated on a Cesium Iodide based flat panel system that simultaneously stores a raw (linear) and processed (non-linear) image for each exposure. It was found that the resulting DQE was equivalent to a conventional standards-compliant DQE with measurement precision, and the gray-scale inversion and linear edge enhancement did not affect the DQE result. While not IEC 62220-1 compliant, it may be adequate for QA programs.

    There is a paucity of literature on direct treatment outcomes for impoverished minority populations. The current study supports the feasibility of successfully treating women for depressive symptoms in community settings where they typically seek care, adding to the small but growing direct knowledge base in this area. The sample of the 2-site study consisted of 91 women seeking treatment for depressive complaints at a homeless shelter program and a municipal hospital psychiatric clinic for Latino patients. Participants were randomly assigned to either a 16-week cognitive-behavioral group or a 16-week supportive/exploratory group for depression. Best-practice features with this population were integrated throughout. Findings showed that both treatment conditions were equally effective in decreasing depressive symptoms (BDI, CES-D) up to 4 months after treatment termination. These changes were paralleled by improvements in self-reported physical health (Duke Physical Profile). No significant differences between treatment conditions were found. Directives for next steps in the current research agenda are offered in efforts to broaden the direct evidence base for treating vulnerable urban women at high risk for depression and other forms of mental illness.

    The effects of autogenic training for anxiety disorders were investigated in a psychiatric setting of a medical school hospital and the predictors of this treatment outcome were identified. Fifty-five patients who meet the DSM-III-R criteria for anxiety disorders were treated individually with autogenic training by the author from October 1981 to October 1995. The medical records of the patients were investigated retrospectively. The results showed that the autogenic training was successful. Twenty-eight patients (51%) were cured, fourteen (25%) much improved, eight (15%) improved and five (9%) unchanged at the end of the treatment. Forty-two patients (76%) were assessed as having had successful treatment. Pretreatment variables, such as patient's clinical characteristics, did not provide a useful guide to the outcome. Four treatment variables did have a bearing on outcome. First, practicing the second standard autogenic training exercise was a satisfactory predictor of a better outcome. Second, practicing generalization training also was a useful predictor. Third, the application of other behavioral treatment techniques was found to be positively associated with outcome. Fourth, longer treatment periods were associated with a better outcome. These findings suggested that autogenic training could be of significant benefit for the treatment of anxiety disorders.

    To evaluate the performance of four kinds of carbon dioxide (CO(2)) absorbents (Medisorb GE Healthcare, Amsorb Plus Armstrong Medical, YabashiLime Yabashi Industries, and Sodasorb LF Grace Performance Chemicals), we measured their dust production, acceptability of colour indicator, and CO(2) absorption capacity in in vitro experimental settings and the concentration of compound A in an inspired anaesthetic circuit during in vivo clinical practice. In vitro, the order of the dust amount was Sodasorb LF > Medisorb > Amsorb Plus = YabashiLime both before and after shaking. The order of the color acceptability was similar: Sodasorb LF > Amsorb Plus = Medisorb > YabashiLime both initially and 16 h after CO(2) exhaustion. During exposure to 200 ml.min(-1) CO(2) in vitro, the period until 1 kg of fresh soda lime allowed inspired CO(2) to increase to 0.7 kPa (as a mark of utilisation of the absorbent) was longer with Medisorb (1978 min) than with the other absorbents (1270-1375 min). In vivo, compound A (1.0% inspired sevoflurane) was detected only when using Medisorb. While Medisorb has the best ability to absorb CO(2), it alone produces compound A.

    Human infections by coelomycetous fungi are becoming more frequent and range from superficial to systemic dissemination. Traumatic implantation of contaminated plant material is the most common cause. The typical morphological feature of these fungi is the production of asexual spores (conidia) within fruiting bodies called conidiomata. This study aimed to determine the distribution of the coelomycetes in clinical samples by a phenotypic and molecular study of a large set of isolates received from a U.S. reference mycological institution and by obtaining the in vitro antifungal susceptibility pattern of nine antifungals against a selected group of isolates. A total of 230 isolates were identified by sequencing the D1 and D2 domains of the large subunit (LSU) nuclear ribosomal RNA (nrRNA) gene and by morphological characterization. Eleven orders of the phylum Ascomycota were identified: Pleosporales (the largest group; 66.1%), Botryosphaeriales (19.57%), Glomerellales (4.35%), Diaporthales (3.48%), Xylariales (2.17%), Hysteriales and Valsariales (0.87%), and Capnodiales, Helotiales, Hypocreales and Magnaporthales (0.43% each). The most prevalent species were Neoscytalidium dimidiatum, Paraconiothyrium spp., Phoma herbarum, Didymella heteroderae, and Epicoccum sorghinum The most common anatomical site of isolation was superficial tissue (66.5%), followed by the respiratory tract (17.4%). Most of the isolates tested were susceptible to the majority of antifungals, and only flucytosine showed poor antifungal activity.

    Gluten is the product of a chemical bond of wheat prolamin proteins (glia- dins and glutenins) in an aqueous me- dium. IgE mediated gluten allergy can be induced either by gluten as an in- gredient in foods or wheat prolamines present in the air. The aim of the study was clinical analysis of 13 patients, who demonstrated elevated levels of gluten specific IgE and identification of the most allergenic protein fractions from several samples of wheat using serum of examined subjects. Clinical analysis showed the occupational allergy to gluten in the form of rhinitis, asthma and airborne dermatistis in 9 subjects, whose symptoms disappeared during isolation from occupational exposure despite the use of a normal diet. In case of 4 patients with severe forms of chronic urticaria and atopic dermatitis, who are also allergic to grass pollen at the same time, the introduction of a gluten-free diet resulted in improvement of health conditions. The study of wheat protein fractions revealed a significant polymorphism dependent on the wheat sample. In the protein fractions, low and high molecular glutenin fractions, and alpha, beta, gamma, and omega-gliadins were separated. It has been shown that the strongest immunogenic effect causes omega-5 gliadin fraction. The removal of this fraction resulted in reduction of skin reactivity evaluated by skin prick test in the studied patients.

    Residential thermostats have been a key element in controlling heating and cooling systems for over sixty years. However, today's modern programmable thermostats (PTs) are complicated and difficult for users to understand, leading to errors in operation and wasted energy. Four separate tests of usability were conducted in preparation for a larger study. These tests included personal interviews, an on-line survey, photographing actual thermostat settings, and measurements of ability to accomplish four tasks related to effective use of a PT. The interviews revealed that many occupants used the PT as an on-off switch and most demonstrated little knowledge of how to operate it. The on-line survey found that 89% of the respondents rarely or never used the PT to set a weekday or weekend program. The photographic survey (in low income homes) found that only 30% of the PTs were actually programmed. In the usability test, we found that we could quantify the difference in usability of two PTs as measured in time to accomplish tasks. Users accomplished the tasks in consistently shorter times with the touchscreen unit than with buttons. None of these studies are representative of the entire population of users but, together, they illustrate the importance of improving user interfaces in PTs.

    At the beginning of the medical encounter, clinicians should elicit patients' agendas several times using open-ended questions. Little is known, however, about how many times physicians really solicit a patient's agenda during follow-up encounters. The objective was to analyze the number of agenda solicitations by physicians, of agendas initiated by physicians, and of patients' spontaneous agendas during the beginning and the entire encounter. We analyzed 68 videotaped follow-up encounters at a university primary care outpatient clinic. The number of different types of agenda setting was searched for and analyzed using negative binomial regression or logistic regression models. Physicians solicited agendas a mean ± SD of 0.8 ± 0.7 times/patient during the first 5 minutes and 1.7 ± 1.2 times/patient during the entire encounter. Physicians in 32.4% of encounters did not solicit the patient agenda, and there were never more than two physician's solicitations during the first 5 minutes. The mean number of physician's solicitations of the patients' agenda was 42% lower among female physicians during the first 5 minutes and 34% lower during the entire encounter. The number of agendas initiated by physicians was 1.2 ± 1.2/patient during the beginning and 3.2 ± 2.3/patient during the entire encounter. In 58.8% of the encounters, patients communicated their agendas spontaneously. There were twice as many patient spontaneous agendas (IRR = 2.12, p = .002) with female physicians than with males. This study showed that agenda solicitation with open-ended questions in follow-up encounters does not occur as often as recommended. There is thus a risk of missing new agendas or agendas that are important to the patient.

    Drinking to cope with negative affect is a drinking pattern that leads to problematic alcohol use both in college and after graduation. Despite theory and correlational evidence to this effect, establishing a link between stress and alcohol consumption among college students in the laboratory has yielded both a limited number of studies and, at times, inconsistent results. The present study attempts to resolve these issues through investigating the effects of an ecologically relevant stressor-ostracism-on alcohol consumption in a clinical laboratory setting. Social drinking college students (N = 40; 55% female) completed a 5-min game of Cyberball and were randomly assigned either to be included or excluded in the virtual ball-toss game. The amount (in ml) of beer consumed in a subsequent mock taste test served as our primary dependent variable, with breath alcohol concentration (BrAC) as a secondary dependent variable. Results indicated that excluded participants reported a trend toward an increase in negative affect from pre- to post-Cyberball, and endorsed significantly lower self-esteem, belonging, control, and belief in a meaningful existence compared to included participants. A significant Sex × Condition effect indicated that excluded women consumed less beer than both included women and excluded men, supported by a nonsignificant trend in BrAC. Men did not differ in their consumption of beer as a result of Cyberball condition. Implications of sex and social context on alcohol use are discussed, as well as ostracism as a method for investigating relationships between social stress and alcohol use.

    When Efexor (venlafaxine) became available in Sweden, a therapeutic drug monitoring (TDM) service was developed in the authors' laboratory. This analytical service was available to all physicians in the country. From March 1996, to November 1997, 797 serum concentration analyses of venlafaxine (VEN) and its main metabolites, O-desmethylvenlafaxine (ODV), N-desmethylvenlafaxine (NDV), and N,O-didesmethylvenlafaxine (DDV) were requested. These samples, each of which was accompanied by clinical information on a specially designed request form, represented 635 inpatients or outpatients, comprising all ages, treated in a naturalistic setting. The first sample per patient, drawn as a trough value in steady state and with documented concomitant medication, was further evaluated pharmacokinetically (n = 187). The doses prescribed were from 37.5 mg/d to 412.5 mg/d. There was a wide interindividual variability of serum concentrations on each dose level, and the mean coefficient of variation of the dose-corrected concentrations (C/D) was 166% for C/D VEN, 60% for C/D ODV, 151% for C/D NDV, and 59% for C/D DDV. The corresponding CV for the ratio ODV/VEN was 110%. However, within patients over time, the C/D VEN and ODV/VEN variation was low, indicating stability in individual metabolizing capacity. Patients over 65 years of age had significantly higher concentrations of C/D VEN and C/D ODV than the younger patients. Women had higher C/D NDV and C/D DDV, and a higher NDV/VEN ratio than men, and smokers showed lower C/D ODV and C/D DDV than nonsmokers. A number of polycombinations of drugs were assessed for interaction screening, and a trend for lowered ODV/VEN ratio was found, predominantly with concomitant medication with CNS-active drug(s) known to inhibit CYP2D6.

    The neck disability index (NDI) is a valid and widely used clinical instrument, which enjoys the recommendation of the World Health Organization for outcome assessment in neck pain. Its psychometric properties have not been investigated in the Nigerian clinical setting. This study investigated the content validity and test-retest reliability of the NDI in order to encourage its integration in the Nigerian clinical setting. Content validity of NDI was assessed through an expert panel review for content relevance/coverage and pretesting. Thirty two subjects with neck pain, recruited through a purposive sampling technique participated in the study. The NDI was administered twice within 48 hours interval. Data were summarized in percentages. Intra class correlation coefficient was used to analyze data for test-retest reliability with alpha set at 0.05. Participants were 1 males, 21 females with a majority within age group 38-57. Twenty four (75%) participants had mild to moderate disability, 7 (21.9%) had severe to complete disability and one individual had no disability. There was a significant correlation (r = 0.969, P=0.01) between the scores obtained from the first administration of the NDI and the second administration. The NDI is a valid and reliable outcome measure and it is recommended for integration into the assessment of neck pain in the Nigerian clinical setting.

    An automatic variational level set segmentation framework for Computer Aided Dental X-rays Analysis (CADXA) in clinical environments is proposed. Designed for clinical environments, the segmentation contains two stages: a training stage and a segmentation stage. During the training stage, first, manually chosen representative images are segmented using hierarchical level set region detection. Then the window based feature extraction followed by principal component analysis (PCA) is applied and results are used to train a support vector machine (SVM) classifier. During the segmentation stage, dental X-rays are classified first by the trained SVM. The classifier provides initial contours which are close to correct boundaries for three coupled level sets driven by a proposed pathologically variational modeling which greatly accelerates the level set segmentation. Based on the segmentation results and uncertainty maps that are built based on a proposed uncertainty measurement, a computer aided analysis scheme is applied. The experimental results show that the proposed method is able to provide an automatic pathological segmentation which naturally segments those problem areas. Based on the segmentation results, the analysis scheme is able to provide indications of possible problem areas of bone loss and decay to the dentists. As well, the experimental results show that the proposed segmentation framework is able to speed up the level set segmentation in clinical environments.

    Objective. To examine pharmacy students’ ownership of, use of, and preference for using a mobile device in a practice setting. Methods. Eighty-one pharmacy students were recruited and completed a pretest that collected information about their demographics and mobile devices and also had them rank the iPhone, iPad mini, and iPad for preferred use in a pharmacy practice setting. Students used the 3 devices to perform pharmacy practice-related tasks and then completed a posttest to again rank the devices for preferred use in a pharmacy practice setting. Results. The iPhone was the most commonly owned mobile device (59.3% of students), and the iPad mini was the least commonly owned (18.5%). About 70% of the students used their mobile devices at least once a week in a pharmacy practice setting. The iPhone was the most commonly used device in a practice setting (46.9% of students), and the iPod Touch was the least commonly used device (1.2%). The iPad mini was the most preferred device for use in a pharmacy practice setting prior to performing pharmacy practice-related tasks (49.4% of students), and was preferred by significantly more students after performing the tasks (70.4%). Conclusion. Pharmacy students commonly use their mobile devices in pharmacy practice settings and most selected the iPad mini as the preferred device for use in a practice setting even though it was the device owned by the fewest students.

    The process of risk assessment which should inform and help identify clinical needs is often seen as a tick box and task-focussed approach. While on the surface this provides a sense of security that forms have been completed, we often fail to communicate in a meaningful manner about the clinical needs identified, which would assist in supporting the care planning delivery processes. A clinical practice improvement (CPI) project implemented a care zoning framework as an evidenced-based process that provides pragmatic support to nurses who are required to continually assess, implement, and evaluate plans to address clinical need across three acute mental health inpatient settings. Risk descriptors informed by the New South Wales (NSW) Mental Health Assessment & Outcome Tools (MHAOT) criteria were developed and described in behavioural contexts in order to improve the project's reliability and translation. A pragmatic traffic light tool was used to share clinical information across three agreed care zones, red (high clinical need), amber (medium clinical need), and green (low clinical need). Additionally nurses were asked to utilise a shift review form in the context of supporting the recording of care zoning and promoting action-orientated note writing. The introduction of care zoning has enthused the nursing teams and the mental health service to adopt care zoning as a supervisory framework that increases their capacity to communicate clinical needs, share information, and gain invaluable support from one another in addressing clinical needs. This includes increased opportunities for staff to feel supported in asking for assistance in understanding and addressing complex clinical presentations.

    With the shift towards interprofessional education to promote collaborative practice, clinical preceptors are increasingly working with trainees from various professions to provide patient care. It is unclear whether and how preceptors modify their existing precepting approach when working with trainees from other professions. There is little information on strategies for this type of precepting, and how preceptors may foster or impede interprofessional collaboration. The purpose of this qualitative description pilot study was to identify current methods preceptors use to teach trainees from other professions in the clinical setting, particularly advanced practice nursing and medical trainees, and to identify factors that support or impede this type of precepting. Data collected through observations and interviews were analyzed by the research team using thematic analysis procedures. Three major themes were identified: 1) a variety of teaching approaches and levels of engagement with trainees of different professions, 2) preceptor knowledge gaps related to curricula, goals, and scope of practice of trainees from other professions, and 3) administrative, structural and logistical elements that impact the success of precepting trainees from different professions in the clinical setting. This study has implications for faculty development and evaluation of current precepting practices in clinical settings.

    Background Skin surface pH is known to influence the dissolution and partitioning of chemicals and may influence exposures that lead to skin diseases. Non-clinical environments (e.g. workplaces) are highly variable, thereby presenting unique measurement challenges that are not typically encountered in clinical settings. Hence, guidelines are needed for consistent measurement of skin surface pH in environments that are difficult to control. Methods An expert workshop was convened at the 5th International Conference on Occupational and Environmental Exposure of Skin to Chemicals to review available data on factors that could influence the determination of skin surface pH in non-clinical settings with emphasis on the workplace as a worst case scenario. Results The key elements of the guidelines are: (i) minimize, to the extent feasible, the influences of relevant endogenous (anatomical position, skin health, time of day), exogenous (hand washing, barrier creams, soaps and detergents, occlusion), environmental (seasonality), and measurement (atmospheric conditions) factors; (ii) report pH measurements results as a difference or percent change (not absolute values) using a measure of central tendency and variability; and (iii) report notable deviations from these guidelines and other relevant factors that may influence measurements. Conclusion Guidelines on the measurement and reporting of skin surface pH in non-clinical settings should promote consistency in data reporting, facilitate inter-comparison of study results, and aid in understanding and preventing occupational skin diseases.

    Purpose dinamic roentgen stereophotogrammetric analysis (RSA), a technique currently based only on customized radiographic equipment, has been shown to be a very accurate method for detecting three-dimensional (3D) joint motion. The aim of the present work was to evaluate the applicability of an innovative RSA set-up for in vivo knee kinematic analysis, using a biplane fluoroscopic image system. To this end, the Authors describe the set-up as well as a possible protocol for clinical knee joint evaluation. The accuracy of the kinematic measurements is assessed. Methods the Authors evaluated the accuracy of 3D kinematic analysis of the knee in a new RSA set-up, based on a commercial biplane fluoroscopy system integrated into the clinical environment. The study was organized in three main phases: an in vitro test under static conditions, an in vitro test under dynamic conditions reproducing a flexion-extension range of motion (ROM), and an in vivo analysis of the flexion-extension ROM. For each test, the following were calculated, as an indication of the tracking accuracy: mean, minimum, maximum values and standard deviation of the error of rigid body fitting. Results in terms of rigid body fitting, in vivo test errors were found to be 0.10±0.05 mm. Phantom tests in static and kinematic conditions showed precision levels, for translations and rotations, of below 0.1 mm/0.2° and below 0.5 mm/0.3° respectively for all directions. Conclusions the results of this study suggest that kinematic RSA can be successfully performed using a standard clinical biplane fluoroscopy system for the acquisition of slow movements of the lower limb. Clinical relevance a kinematic RSA set-up using a clinical biplane fluoroscopy system is potentially applicable and provides a useful method for obtaining better characterization of joint biomechanics.

    Although poor clinic attendance is associated with increased morbidity and mortality among HIV-infected individuals, less is known about predictors of retention and the acceptability of targeted interventions to increase regular clinic attendance. To better understand which patients are at risk for irregular clinic attendance and to explore interventions to aid in retention to care, we surveyed patients attending two outpatient HIV clinics affiliated with the University of California, San Francisco. A total of 606 participants were surveyed, and the analysis was restricted to the 523 male respondents. Of this group, 45% (N = 299) reported missing at least one visit a year. Missing a clinic visit was associated with being African American (aOR = 1.99; 95%CI 1.12-3.52), being a man who has sex with both men and women (aOR=2.72; 95%CI 1.16-6.37), and reporting at least weekly methamphetamine use (aOR=5.79; 95%CI 2.47-13.57). Participants who reported a monthly income greater than $2000 were less likely to miss an appointment (aOR = 0.56; 95%CI 0.34-0.93). Regarding possible retention interventions, most patients preferred phone calls over other forms of support. These findings support the need for ongoing engagement support with particular attention to at-risk sub-groups.

    Purpose of Review Biomarkers of type 1 diabetes are important for assessing risk of developing disease, monitoring disease progression, and determining responses to clinical treatments. Here we review recent advances in the development of biomarkers of type 1 diabetes with a focus on their utility in clinical trials. Recent Findings Measurements of auto antibodies and metabolic outcomes have been the foundation of monitoring type 1 diabetes for the past 20 years. Recent advancements have lead to improvements in T cell specific assays that have been used in large-scale clinical trials to measure antigen specific T cell responses. Additionally, new tools are being developed for the measurement of β cell mass and death that will allow for more direct measurement of disease activity. Lastly, recent studies have used both immunologic and non-immunologic biomarkers to identify responders to treatments in clinical trials. Summary Use of biomarkers in the study of type 1 diabetes have largely not changed over the past 20 years, however recent advancements in the field are establishing new techniques that allow for more precise monitoring of disease progression. These new tools will ultimately lead to an improvement in understanding of disease and will be utilized in clinical trials. PMID:24937037

    A national workgroup convened by the Centers for Disease Control and Prevention identified principles and made recommendations for standardizing the description of sequence data contained within the variant file generated during the course of clinical next-generation sequence analysis for diagnosing human heritable conditions. The specifications for variant files were initially developed to be flexible with regard to content representation to support a variety of research applications. This flexibility permits variation with regard to how sequence findings are described and this depends, in part, on the conventions used. For clinical laboratory testing, this poses a problem because these differences can compromise the capability to compare sequence findings among laboratories to confirm results and to query databases to identify clinically relevant variants. To provide for a more consistent representation of sequence findings described within variant files, the workgroup made several recommendations that considered alignment to a common reference sequence, variant caller settings, use of genomic coordinates, and gene and variant naming conventions. These recommendations were considered with regard to the existing variant file specifications presently used in the clinical setting. Adoption of these recommendations is anticipated to reduce the potential for ambiguity in describing sequence findings and facilitate the sharing of genomic data among clinical laboratories and other entities.

    Kolb's Learning Style Inventory and Environmental Press Questionnaire were used to study 68 third-year baccalaureate nursing students' learning styles and perceptions of environmental press differences in medical-surgical and psychiatric nursing settings from the experiential learning theory perspective. Evidence for a hypothesized match between predominating student learning styles and predominating environmental press was sought. As hypothesized, student learning styles were found to be predominantly concrete as was the predominating environmental press in both nursing settings. Medical-surgical and psychiatric nursing settings did not differ significantly from environmental press. A profile of competencies felt to be important in nursing emerged with concrete people-oriented competencies rating higher than abstract competencies.

    Automated knowledge acquisition is an important research issue to solve the bottleneck problem in developing expert systems. Although many inductive learning methods have been proposed for this purpose, most of the approaches focus only on inducing classification rules. However, medical experts also learn other information important for diagnosis from clinical cases. In this paper, a rule induction method is introduced, which extracts not only classification rules but also other medical knowledge needed for diagnosis. This system is evaluated on a clinical database of headache, whose experimental results show that our proposed method correctly induces diagnostic rules and estimates the statistical measures of rules.

    In the health field, clinical information is the raw material for the clinician delivering health services. Therefore, the clinical information available to the physician is often incomplete or even non¿existent upon consultation. Furthermore, the reconstruction of the medical history, which is the most important source of data for the clinician to establish a diagnosis and initiate a treatment, suffers from many constraints. The smart card, like the one used in Quebec's project, could ease the physician's decision-making by allowing fast access to accurate and pertinent data. The smart card is a major asset in the present health system.

    Although there is a growing literature on the incidence of occurrence and reporting of occupational exposures in clinics in dental schools, the contributing factors to fear of such injuries and their dynamic evolution over time remain unstudied. It is hypothesized that fear of occupational exposures is a function of estimated likelihood of such events and their perceived importance. Individual personality factors and situational circumstances are also thought to play a role, although it is believed that these factors recede in importance as students gain direct knowledge through clinical experience. Path analysis methods are applied to longitudinal survey data in a single dental school to confirm these hypotheses.

    Background The purpose of this study was to identify recommended practices for computerized clinical decision support (CDS) development and implementation and for knowledge management (KM) processes in ambulatory clinics and community hospitals using commercial or locally developed systems in the U.S. Methods Guided by the Multiple Perspectives Framework, the authors conducted ethnographic field studies at two community hospitals and five ambulatory clinic organizations across the U.S. Using a Rapid Assessment Process, a multidisciplinary research team: gathered preliminary assessment data; conducted on-site interviews, observations, and field surveys; analyzed data using both template and grounded methods; and developed universal themes. A panel of experts produced recommended practices. Results The team identified ten themes related to CDS and KM. These include: 1) workflow; 2) knowledge management; 3) data as a foundation for CDS; 4) user computer interaction; 5) measurement and metrics; 6) governance; 7) translation for collaboration; 8) the meaning of CDS; 9) roles of special, essential people; and 10) communication, training, and support. Experts developed recommendations about each theme. The original Multiple Perspectives framework was modified to make explicit a new theoretical construct, that of Translational Interaction. Conclusions These ten themes represent areas that need attention if a clinic or community hospital plans to implement and successfully utilize CDS. In addition, they have implications for workforce education, research, and national-level policy development. The Translational Interaction construct could guide future applied informatics research endeavors. PMID:22333210

    The spectrum of somatic alterations in hematologic malignancies includes substitutions, insertions/deletions (indels), copy number alterations (CNAs), and a wide range of gene fusions; no current clinically available single assay captures the different types of alterations. We developed a novel next-generation sequencing-based assay to identify all classes of genomic alterations using archived formalin-fixed paraffin-embedded blood and bone marrow samples with high accuracy in a clinically relevant time frame, which is performed in our Clinical Laboratory Improvement Amendments–certified College of American Pathologists–accredited laboratory. Targeted capture of DNA/RNA and next-generation sequencing reliably identifies substitutions, indels, CNAs, and gene fusions, with similar accuracy to lower-throughput assays that focus on specific genes and types of genomic alterations. Profiling of 3696 samples identified recurrent somatic alterations that impact diagnosis, prognosis, and therapy selection. This comprehensive genomic profiling approach has proved effective in detecting all types of genomic alterations, including fusion transcripts, which increases the ability to identify clinically relevant genomic alterations with therapeutic relevance.

    Copy number variants (CNVs) have a major role in the etiology of autism spectrum disorders (ASD), and several of these have reached statistical significance in case–control analyses. Nevertheless, current ASD cohorts are not large enough to detect very rare CNVs that may be causative or contributory (that is, risk alleles). Here, we use a tiered approach, in which clinically significant CNVs are first identified in large clinical cohorts of neurodevelopmental disorders (including but not specific to ASD), after which these CNVs are then systematically identified within well-characterized ASD cohorts. We focused our initial analysis on 48 recurrent CNVs (segmental duplication-mediated ‘hotspots') from 24 loci in 31 516 published clinical cases with neurodevelopmental disorders and 13 696 published controls, which yielded a total of 19 deletion CNVs and 11 duplication CNVs that reached statistical significance. We then investigated the overlap of these 30 CNVs in a combined sample of 3955 well-characterized ASD cases from three published studies. We identified 73 deleterious recurrent CNVs, including 36 deletions from 11 loci and 37 duplications from seven loci, for a frequency of 1 in 54; had we considered the ASD cohorts alone, only 58 CNVs from eight loci (24 deletions from three loci and 34 duplications from five loci) would have reached statistical significance. In conclusion, until there are sufficiently large ASD research cohorts with enough power to detect very rare causative or contributory CNVs, data from larger clinical cohorts can be used to infer the likely clinical significance of CNVs in ASD.

    2008-01-01

    Background The ability for patients to access and consume sufficient quantities of nutrients to meet recommendations for wound management is vital if decline in nutritional status during hospital admission is to be prevented. This study aims to investigate menu quality, consumption patterns, and changes in nutritional status for inpatients with wounds. Methods Wound healing recommendations were compared against the nutrient content of the inpatient menu. Individual intakes were compared to estimated requirements: energy using the Schofield equation; protein using wound healing recommendations; vitamin A, C, and zinc using the recommended daily intake (RDI). Results The inpatient menu did not provide sufficient energy or zinc to meet the estimated average requirement while the ordering practices of participants allowed all RDI to be achieved except for zinc. Actual intake fell below recommendations: 62%, 41%, 55%, and 79% of patients not meeting energy, minimum protein requirements, vitamin A or zinc RDI respectively. A nonsignificant trend for weight loss, particularly fat mass, was observed over time. Conclusion Inpatients with wounds are at risk of being unable to consume sufficient quantities of nutrients important for healing and prevention of decline in nutritional status. This is despite the menu seemingly providing sufficient nutrients. More attention to education, encouragement, and supplementation are recommended. PMID:21197335

    Complex Regional Pain Syndrome (CRPS) is a persistent pain condition that remains incompletely understood and challenging to treat. Historically, a wide range of different outcome measures have been used to capture the multidimensional nature of CRPS. This has been a significant limiting factor in the advancement of our understanding of the mechanisms and management of CRPS.In 2013, an international consortium of patients, clinicians, researchers and industry representatives was established, to develop and agree on a minimum core set of standardised outcome measures for use in future CRPS clinical research, including but not limited to clinical trials within adult populationsThe development of a core measurement set was informed through workshops and supplementary work, using an iterative consensus process. 'What is the clinical presentation and course of CRPS, and what factors influence it?' was agreed as the most pertinent research question that our standardised set of patient-reported outcome measures should be selected to answer. The domains encompassing the key concepts necessary to answer the research question were agreed as: pain, disease severity, participation and physical function, emotional and psychological function, self efficacy, catastrophizing and patient's global impression of change. The final core measurement set included the optimum generic or condition-specific patient-reported questionnaire outcome measures, which captured the essence of each domain, and one clinician reported outcome measure to capture the degree of severity of CRPS. The next step is to test the feasibility and acceptability of collecting outcome measure data using the core measurement set in the CRPS population internationally.

    The development of new massive sequencing techniques has now made it possible to significantly reduce the time and costs of whole-genome sequencing (WGS). Although WGS will soon become a routine testing tool, new ethical issues have surfaced. In light of these concerns, a systematic review of papers published by expert authors on IC or specific ethical issues related to IC for WGS analysis in the clinical setting has been conducted using the Pubmed, Embase and Cochrane Library databases. Additionally, a search was conducted for international ethical guidelines for genetic studies published by scientific societies and ethical boards. Based on these documents, a minimum set of information to be provided to patients in the IC form was determined. Fourteen and seven documents from the database search and from scientific societies, respectively, were selected. A very high level of consistency between them was found regarding the recommended IC form content. Pre-test counselling and general information common to all genetic tests should be included in the IC form for WGS for diagnostic purposes, but additional information addressing specific issues on WGS are proposed, such as a plan for the ethical, clinically oriented return of incidental findings. Moreover, storage of additional information for future use should also be agreed upon with the patient in advance. Recommendations for WGS studies in the clinical setting concerning both the elements of information and the process of obtaining the IC as well as how to handle the results obtained are proposed.

    The National Cancer Institute (NCI)-funded cooperative group cancer clinical trial system develops experimental therapies and often collects samples from patients for correlative research. The cooperative group bank (CGB) system maintains biobanks with a current policy not to return research results to individuals. An online survey was created, and 10 directors of CGBs completed the surveys asking about understanding and attitudes in changing policies to consider return of incidental findings (IFs) and individual research results (IRRs) of health significance. The potential impact of the 10 consensus recommendations of Wolf et al. presented in this issue are examined. Reidentification of samples is often not problematic; however, changes to the current banking and clinical trial systems would require significant effort to fulfill an obligation of recontact of subjects. Additional resources, as well as a national advisory board would be required to standardize implementation.

    In industry, hospital, clinic, laboratory or office, professionals are continually faced with “all size” of problems which can be successfully answered by using investigative scientific methods. The recognition and formulation of an existing problem followed by the desire to seek an answer are the first major steps. Collecting and analyzing data, followed by valid scientific conclusion completes the picture. Professional success means knowing most about something, not something about most. Investigation-research is a particular pattern in weaving, made of organized curiosity, skillful analysis, inventive thinking and professional objectivity. The purpose of the article remains to identify fundamental questions which emerge from clinical observations and practice, to identify and project needed research and to guide the finding of scientific answers.

    Background In malaria endemic regions people are commonly infected with multiple species of malaria parasites but the clinical impact of these Plasmodium co-infections is unclear. Differences in transmission seasonality and transmission intensity between endemic regions have been suggested as important factors in determining the effect of multiple species co-infections. Principal Findings In order to investigate the impact of multiple-species infections on clinical measures of malaria we carried out a cross-sectional community survey in Malawi, in 2002. We collected clinical and parasitological data from 2918 participants aged >6 months, and applied a questionnaire to measure malaria morbidity. We examined the effect of transmission seasonality and intensity on fever, history of fever, haemoglobin concentration ([Hb]) and parasite density, by comparing three regions: perennial transmission (PT), high intensity seasonal transmission (HIST) and low intensity seasonal transmission (LIST). These regions were defined using multi-level modelling of PCR prevalence data and spatial and geo-climatic measures. The three Plasmodium species (P. falciparum, P. malariae and P. ovale) were randomly distributed amongst all children but not adults in the LIST and PT regions. Mean parasite density in children was lower in the HIST compared with the other two regions. Mixed species infections had lower mean parasite density compared with single species infections in the PT region. Fever rates were similar between transmission regions and were unaffected by mixed species infections. A history of fever was associated with single species infections but only in the HIST region. Reduced mean [Hb] and increased anaemia was associated with perennial transmission compared to seasonal transmission. Children with mixed species infections had higher [Hb] in the HIST region. Conclusions Our study suggests that the interaction of Plasmodium co-infecting species can have protective effects against

    2010-09-01

    The American Academy of Pediatrics promotes the inclusion of the gynecologic examination in the primary care setting within the medical home. Gynecologic issues are commonly seen by clinicians who provide primary care to adolescents. Some of the most common concerns include questions related to pubertal development; menstrual disorders such as dysmenorrhea, amenorrhea, oligomenorrhea, and abnormal uterine bleeding; contraception; and sexually transmitted and non-sexually transmitted infections. The gynecologic examination is a key element in assessing pubertal status and documenting physical findings. Most adolescents do not need an internal examination involving a speculum or bimanual examination. However, for cases in which more extensive examination is needed, the primary care office with the primary care clinician who has established rapport and trust with the patient is often the best setting for pelvic examination. This report reviews the gynecologic examination, including indications for the pelvic examination in adolescents and the approach to this examination in the office setting. Indications for referral to a gynecologist are included. The pelvic examination may be successfully completed when conducted without pressure and approached as a normal part of routine young women's health care.

    Introduction: Data quality and fitness for analysis are crucial if outputs of analyses of electronic health record data or administrative claims data should be trusted by the public and the research community. Methods: We describe a data quality analysis tool (called Achilles Heel) developed by the Observational Health Data Sciences and Informatics Collaborative (OHDSI) and compare outputs from this tool as it was applied to 24 large healthcare datasets across seven different organizations. Results: We highlight 12 data quality rules that identified issues in at least 10 of the 24 datasets and provide a full set of 71 rules identified in at least one dataset. Achilles Heel is a freely available software that provides a useful starter set of data quality rules with the ability to add additional rules. We also present results of a structured email-based interview of all participating sites that collected qualitative comments about the value of Achilles Heel for data quality evaluation. Discussion: Our analysis represents the first comparison of outputs from a data quality tool that implements a fixed (but extensible) set of data quality rules. Thanks to a common data model, we were able to compare quickly multiple datasets originating from several countries in America, Europe and Asia. PMID:28154833

    Pseudomonas putida strains are frequent inhabitants of soil and aquatic niches and they are occasionally isolated from hospital environments. As the available iron sources in human tissues, edaphic, and aquatic niches are different, we have analyzed iron-uptake related genes in different P. putida strains that were isolated from all these environments. We found that these isolates can be grouped into different clades according to the genetics of siderophore biosynthesis and recycling. The pyoverdine locus of the six P. putida clinical isolates that have so far been completely sequenced, are not closely related; three strains (P. putida HB13667, HB3267, and NBRC14164T) are grouped in Clade I and the other three in Clade II, suggesting possible different origins and evolution. In one clinical strain, P. putida HB4184, the production of siderophores is induced under high osmolarity conditions. The pyoverdine locus in this strain is closely related to that of strain P. putida HB001 which was isolated from sandy shore soil of the Yellow Sea in Korean marine sand, suggesting their possible origin, and evolution. The acquisition of two unique TonB-dependent transporters for xenosiderophore acquisition, similar to those existing in the opportunistic pathogen P. aeruginosa PAO, is an interesting adaptation trait of the clinical strain P. putida H8234 that may confer adaptive advantages under low iron availability conditions.

    Data to fully evaluate the effectiveness of many commonly used interventions in the clinical pain management setting are inadequate. Clinical data collected for patient management often are not based on validated instruments, and this impedes the ability to conduct longitudinal research. To address these needs, modified patient intake and return visit forms were established and the Assessment of Pain Outcomes Longitudinal Electronic Data Capture system was developed. Data collection has been underway since November 22, 2010. As of December 7, 2011, 951 New Patient and 688 Return Visit forms had been entered. The forms have been well received, with less than 6.5% failing to complete at least 90% of the data requested. Accuracy of data entry is excellent, with an error rate of 1 in 11,250 potential data points. Data output converts easily to standard statistical programs. The creation of a pain outcomes database using validated measures and clinically relevant data is feasible.

    Reality Orientation (RO) was developed as a strategy to assist people with dementia to improve their orientation and everyday function. Although its efficacy has been extensively studied in long-term care facilities, its effectiveness has rarely been examined in acute care settings. The aim of this review was to examine the studies cited in systematic reviews of RO to determine the potential clinical usefulness and the feasibility of using RO in acute care settings. Based on this information, the authors make recommendations for future research in this area. The feasibility of implementing RO in acute care poses challenges because of the short time a patient is in hospital and their ability to participate given their acute medical condition. Although the efficacy and feasibility of using RO in acute care settings have not been sufficiently examined, its potential to improve care should not be ignored. A comprehensive and rigorous study is necessary to investigate the usefulness of RO in the acute care setting and to help establish clinical guidelines for dementia care in the context of acute care nursing.

    Background Patient-generated health data (PGHD) are health-related data created or recorded by patients to inform their self-care and understanding about their own health. PGHD is different from other patient-reported outcome data because the collection of data is patient-driven, not practice- or research-driven. Technical applications for assisting patients to collect PGHD supports self-management activities such as healthy eating and exercise and can be important for preventing and managing disease. Technological innovations (eg, activity trackers) are making it more common for people to collect PGHD, but little is known about how PGHD might be used in outpatient clinics. Objective The objective of our study was to examine the experiences of health care professionals who use PGHD in outpatient clinics. Methods We conducted an evaluation of Project HealthDesign Round 2 to synthesize findings from 5 studies funded to test tools designed to help patients collect PGHD and share these data with members of their health care team. We conducted semistructured interviews with 13 Project HealthDesign study team members and 12 health care professionals that participated in these studies. We used an immersion-crystallization approach to analyze data. Our findings provide important information related to health care professionals’ attitudes toward and experiences with using PGHD in a clinical setting. Results Health care professionals identified 3 main benefits of PGHD accessibility in clinical settings: (1) deeper insight into a patient’s condition; (2) more accurate patient information, particularly when of clinical relevance; and (3) insight into a patient’s health between clinic visits, enabling revision of care plans for improved health goal achievement, while avoiding unnecessary clinic visits. Study participants also identified 3 areas of consideration when implementing collection and use of PGHD data in clinics: (1) developing practice workflows and protocols

    This study examined the test-retest reliability of oxygen cost (ml·kg-1·min-1) during level walking in individuals with acquired brain injury (ABI). Ten individuals with ABI (5 men, 5 women) (Traumatic brain injury, 1, central pontine myelinolysis, 1, stroke 8) and 21 healthy controls (11 men, 10 women). Measurements of gross and net (walking minus resting) oxygen consumption (ml·kg-1·min-1), and oxygen cost (ml·kg-1·min-1) during level walking at self-selected speeds. Measurements were taken on two occasions within one week. Oxygen cost was significantly lower (p < 0.05) in individuals with ABI on the second test versus the first test. Percentage variability in oxygen cost from test to re-test ranged from 14.7 to 17.3% in the control group and from 17.4 to 20.8% in the brain injury group. Clinical populations may demonstrate a significant decrease in oxygen cost between testing occasions. Individuals require at least one period of familiarisation if oxygen cost is used as an outcome measure during level walking in clinical groups. The amount of familiarisation has yet to be investigated in individuals with ABI. Key Points Individuals with brain injury during level walking May demonstrate a significant decrease in oxygen cost between testing occasions. May require at least one period of familiarisation if oxygen cost is used as an outcome measure The degree of familiarisation required in this clinical group needs further investigation PMID:24482582

    OBJECTIVE: To determine the validity of an algorithm used by primary care health workers to identify children with symptomatic human immunodeficiency virus (HIV) infection. This HIV algorithm is being implemented in South Africa as part of the Integrated Management of Childhood Illness (IMCI), a strategy that aims to improve childhood morbidity and mortality by improving care at the primary care level. As AIDS is a leading cause of death in children in southern Africa, diagnosis and management of symptomatic HIV infection was added to the existing IMCI algorithm. METHODS: In total, 690 children who attended the outpatients department in a district hospital in South Africa were assessed with the HIV algorithm and by a paediatrician. All children were then tested for HIV viral load. The validity of the algorithm in detecting symptomatic HIV was compared with clinical diagnosis by a paediatrician and the result of an HIV test. Detailed clinical data were used to improve the algorithm. FINDINGS: Overall, 198 (28.7%) enrolled children were infected with HIV. The paediatrician correctly identified 142 (71.7%) children infected with HIV, whereas the IMCI/HIV algorithm identified 111 (56.1%). Odds ratios were calculated to identify predictors of HIV infection and used to develop an improved HIV algorithm that is 67.2% sensitive and 81.5% specific in clinically detecting HIV infection. CONCLUSIONS: Children with symptomatic HIV infection can be identified effectively by primary level health workers through the use of an algorithm. The improved HIV algorithm developed in this study could be used by countries with high prevalences of HIV to enable IMCI practitioners to identify and care for HIV-infected children. PMID:14997238

    The global population is aging. With the high prevalence of dementia and functional decline in older Americans, many aging adults with disabilities reside in nursing homes in their final stage of life. Immunosenescence, multiple comorbid disease, and grouped quarter living all coalesce in nursing home residents to increase the risk for infectious disease. The unique issues involved with diagnosis, prognosis, and management of infectious diseases in nursing home residents make research based in the nursing home setting both necessary and exciting for the physician investigator. This review discusses the opportunities and challenges involved with research of the evolving public health problem of infections among nursing home residents. PMID:20822459

    Purpose The aims of this study were to determine the prevalence of vitreomacular adhesion (VMA) in a random sample of clinical patients at three US retina clinics and to assess comorbid retinal conditions, ocular diseases, prior treatment history, and other medical histories. Patients and methods This observational, retrospective cohort study was based on patients from the Doheny Eye Centers, Duke Eye Center, and Tufts Medical Center who received a bilateral spectral domain optical coherence tomography (SD-OCT) scan (one scan/eye) for clinical evaluation with available medical records. The study had three phases: 1) collection of retrospective patient data; 2) review of OCT scans at a reading center to assess VMA and associated conditions; and 3) analyses and reporting of data on the prevalence of VMA, patient demographics, and comorbid conditions. Data were obtained from electronic health records and OCT grading forms. Outcome measures from bilateral SD-OCT scans and medical records included OCT evaluation of VMA and retinal comorbid conditions. Results In 719 patients with 1,483 reviewable OCT scans, the prevalence of VMA was estimated at 14.74% (90% CI, 12.58%–16.92%). The prevalence of unilateral VMA was estimated at 12.39%, while bilateral VMA was 2.36%. In patients with VMA, 34 out of 123 eyes with VMA (27.64%) also had fovea deformed by vitreomacular traction. Macular hole (MH) was significantly more prevalent in VMA-diagnosed eyes versus non-VMA-diagnosed eyes (6.5% versus 1.9%; P=0.02). There was a significantly higher incidence of full-thickness MH (P=0.008), operculum/flaps (P<0.0001), and lamellar or pseudo-holes (P=0.048) in VMA-diagnosed versus non-VMA-diagnosed eyes. Age, MH as a comorbid condition, full-thickness MH, lamellar or pseudo-holes, and operculum were predictive of a VMA diagnosis. Conclusion The prevalence of VMA was estimated at 14.74% in a random sample of patients from three retina clinics. VMA diagnosis can be predicted by factors

    Introduction Fetal distress has been shown to contribute to the increasing caesarean section rate. There has been controversy on the usefulness of clinical diagnosis of fetal distress using only the intermittent counting of the fetal heart rate and/or passage of meconium-stained liquor. Aim To evaluate the clinical diagnosis of fetal distress and the perinatal outcome. Materials and Methods This was a retrospective study in which the case records of the patients, who were diagnosed of fetal distress at Federal Teaching Hospital, Abakaliki, Nigeria, from January 1, 2008 to December 31, 2014, were collated. The statistical analysis was done using the Statistical Package for Social Sciences version 17 software (SPSS Inc., Chicago IL, USA). Results Out of the 15,640 deliveries carried out within the study period, 3,761 (24.05%) deliveries were through caesarean section. A total of 326 (8.9%) of the 3,761 caesarean sections were due to fetal distress within the study period. More so, a total of 227 (70.9%) babies were born with ≥ 7 Apgar score at the 1st minute of delivery. The perinatal mortality rate was 31.25 per 1000 deliveries. Though birth asphyxia was recorded more on babies of mothers that had fresh meconium-stained liquor and whose decision-intervention interval was more than 30 minutes when compared with those without any of the two conditions, there was no statistical significant difference between them. Conclusion The clinical diagnosis of fetal distress is accurate in 29.1% of the cases. However, it has led to an unnecessary caesarean section in the remaining 70.9% of the parturients. In order to reduce this high trend of unnecessary caesarean sections due to clinical diagnosis of fetal distress in this environment, antepartum fetal assessment with non-stress test or biophysical profile and intrapartum use of continuous electronic fetal monitoring should be used to confirm or refute the fetal distress before any surgical intervention.

    In this paper, we present the concept of feedbackability and how to identify the Minimum Feedbackability Set of an arbitrary complex directed network. Furthermore, we design an estimator and a feedback controller accessing one MFS to realize actual feedback control, i.e. control the system to our desired state according to the estimated system internal state from the output of estimator. Last but not least, we perform numerical simulations of a small linear time-invariant dynamics network and a real simple food network to verify the theoretical results. The framework presented here could make an arbitrary complex directed network realize actual feedback control and deepen our understanding of complex systems.

    Study Objectives: To translate, back-translate and cross-language validate (English/Spanish) the Sleep Heart Health Study Sleep Habits Questionnaire for use with Spanish-speakers in clinical and research settings. Methods: Following rigorous translation and back-translation, this cross-sectional cross-language validation study recruited bilingual participants from academic, clinic, and community-based settings (N = 50; 52% women; mean age 38.8 ± 12 years; 90% of Mexican heritage). Participants completed English and Spanish versions of the Sleep Habits Questionnaire, the Epworth Sleepiness Scale, and the Acculturation Rating Scale for Mexican Americans II one week apart in randomized order. Psychometric properties were assessed, including internal consistency, convergent validity, scale equivalence, language version intercorrelations, and exploratory factor analysis using PASW (Version18) software. Grade level readability of the sleep measure was evaluated. Results: All sleep categories (duration, snoring, apnea, insomnia symptoms, other sleep symptoms, sleep disruptors, restless legs syndrome) showed Cronbach α, Spearman-Brown coefficients and intercorrelations ≥ 0.700, suggesting robust internal consistency, correlation, and agreement between language versions. The Epworth correlated significantly with snoring, apnea, sleep symptoms, restless legs, and sleep disruptors) on both versions, supporting convergent validity. Items loaded on 4 factors accounted for 68% and 67% of the variance on the English and Spanish versions, respectively. Conclusions: The Spanish-language Sleep Habits Questionnaire demonstrates conceptual and content equivalency. It has appropriate measurement properties and should be useful for assessing sleep health in community-based clinics and intervention studies among Spanish-speaking Mexican Americans. Both language versions showed readability at the fifth grade level. Further testing is needed with larger samples. Citation: Baldwin CM

    Objectives The purpose of this study was to better understand the prevalence and correlates of substance use behaviors among HIV-infected adolescents in HIV care settings. Methods A cross-sectional sample of 2216 youth living with HIV (YLWH; ages 12-26) was recruited through the Adolescent Trials Network for HIV Interventions. Participants completed a one-time survey on sociodemographic factors, substance use and health behaviors. We used logistic regression models to understand the correlates of substance use outcomes. Results Overall, weekly or more frequent tobacco use was reported by 32.9% of participants, 27.5% marijuana use, and 21.3% alcohol use; and 22.5% reported any other illicit drug use. In multivariable models, young MSM had higher odds of reporting each substance use behavior, and transgender women had increased odds of marijuana and other illicit drug use. Criminal justice involvement, unstable housing, condomless sex, and suboptimal antiretroviral therapy was associated with increased risk of substance use behaviors. Conclusions Study findings highlight the need for regular screening for substance use in HIV care settings in order to improve access to and delivery of culturally competent substance use prevention and treatment services.

    Evidence indicates that nurses regularly experience bullying within the workplace which has the potential for health and social effects, as well as worker attrition. Literature suggests that nursing students are exposed to workplace violence during clinical placements including from health professionals and mentors, however little is known about midwifery students. This study sought to examine undergraduate midwifery students' experiences of workplace violence during clinical placements. A cross-sectional approach using a paper-based survey, the Paramedic Workplace Questionnaire, was used to solicit the information. Students were exposed to workplace violence with the main act being intimidation (30%), verbal abuse (17%), physical abuse (3%), and sexual harassment (3%). In more than three-quarters of the incidents the students had some level of apprehension or were frightened as a result of the violence. Students responded to the acts of violence with changes to emotions, self-confidence, and a desire to "give up". This paper demonstrates ways in which midwifery students are vulnerable to potential workplace violence from various sources. Support mechanisms need to be developed to ensure this can be minimised.

    Prevention of HIV transmission from patients living with HIV (PLH) is a high national priority and strategies that are easy to implement and sustain to eliminate sexual transmission acts among PLH are needed. We evaluated a brief intervention that focused primarily on the enhancing motivations and encouraging PLH to act in accordance with their values without providing the intensity of the existing evidence-based programs for PLH. Using a quasiexperimental design, six medical clinics in Los Angeles County, CA, were evaluated across three intervention conditions: 1) computerized delivery; 2) provider delivery; or 3) standard care. We examined longitudinal changes in patients' reports of the number of HIV-negative (HIV-) or serostatus-unknown sexual partners and the number of unprotected vaginal and anal sex acts. Among 566 PLH, PLH in the computerized delivery condition reported a significant decrease in the number of HIV-/unknown sexual partners compared with the provider delivery and standard care conditions and a significant decrease in the number of unprotected sex acts in comparison to the standard care condition. Computerized motivational interventions delivered in waiting rooms at medical clinics may be an efficient strategy to reduce unprotected sex acts among PLH.

    As the traditional definition of "medical ethics" has recently changed markedly with advances in medical knowledge and technology, medical doctors and researchers in Japan are required to understand and apply both research and clinical ethics. Quite frequently, ethical problems in clinical settings cannot be addressed by the simple application of good will, hard work, and perseverance by medical personnel. The Ministry of Health, Labour and Welfare (MHLW) and the Ministry of Education, Culture, Sports, Science and Technology (MEXT) have jointly published "Ethical Guidelines for Clinical Studies;" however, clear guidelines (legal, ministerial, or governmental) outlining the expectations regarding clinical ethics do not exist. All medical personnel face deep ethical dilemmas. In these instances, if the fulfillment of 'ethics' relies solely on the capacity of personnel to apply their own individual moral efforts, the result will be burn-out among these workers who have a strong sense of responsibility. In order to avoid this, a system which comprises multiple physicians, nurses, and other personnel must be established, allowing collaboration when an appropriate response is required. A major factor supporting this approach is the offering of Clinical Ethics Consultations.

    This article analyzes the process whereby physicians and patients set the agenda for medical interviews. Applying a conversation analytic perspective to the analysis of 22 videotapes of primary care interviews at a large, urban, teaching and research hospital, a 3-stage model is developed, consisting of (a) an opening sequence, (b) an initial statement of concerns by the patient, and (c) the negotiation process. The analysis illustrates the critical function of the opening verbal exchanges, showing how patient responses to the physician's first question and subsequent queries and summaries by the physician are intricately interwoven. The interaction at the very beginning of the interview is shown to significantly alter the ensuing interaction. The analysis provides a discursive framework for analyzing problematic communication during the primary care interview.

    Technologies are not always successfully implemented into practice. This study elicited experiences of acute care providers with the introduction of technology and identified barriers and facilitators in the implementation process. A qualitative study using one-on-one interviews among a purposeful sample of 19 physicians and nurses within 10 emergency departments and intensive care units was performed. Grounded theory, iterative data analysis and the constant comparative method were used to inductively generate ideas and build theories. Five major categories emerged: decision-making factors, the impact on practice, technology's perceived value, facilitators and barriers to implementation. Barriers included negative experiences, age, infrequent use and access difficulties. A positive outlook, sufficient training, support staff and user friendliness were facilitators. This study describes strategies implicated in the successful implementation of newly adopted technology in acute care settings. Improved implementation methods and evaluation of implementation processes are necessary for successful adoption of new technology.

    Differences and relations between effects of acupuncture therapy and sham acupuncture are systematically analyzed in this article through the influential factors of acupuncture effect. And it is held that sham acupuncture effect is not exactly equal to placebo effect. The effects of both acupuncture and sham acupuncture are composed by specific effects and non-specific effects, and the differences of non-specific effects between acupunc ture and sham acupuncture can be minimized furthest with blinding and randomized method. Therefore, the difference of acupuncture and sham acupuncture treatment rests with the degree of differences of the specific effects. Only when both of the specific effect of acupuncture and the effect of acupuncture are minimized, can it be applied as the ideal placebo control. Consequently when placebo acupunture are setted up, factors such as the body condition, site of stimulation and stimulation parameters which can influence the specific effect of acupuncture should be taken into consideration to produce the relatively minimum specific effect.

    Advancing age is associated with an increased risk of herpes zoster (shingles) infection and latent effects such as postherpetic neuralgia. The herpes zoster vaccine is recommended in those 60 years of age and older and has been shown to prevent both the primary disease and associated complications. While this recommendation applies to those living in long-term care facilities, there is little clinical evidence to support use in this population. Additionally, there are logistical barriers that may complicate the use of the vaccine. The article examines the evidence for vaccinating residents in long-term care facilities and discusses logistical barriers to vaccination. Pharmacists and providers may consider life expectancy and other factors when evaluating which patients should receive the vaccination.

    Wisdom can be defined as expert knowledge in the fundamental pragmatics of life. Examined here is whether clinical practice may facilitate access to and acquisition of such knowledge. Spontaneous think-aloud responses to 2 wisdom-related dilemmas from young (M = 32 years) and older (M = 70 years) clinicians were compared with responses obtained from other professionals. Raters judged clinicians' responses as higher on 5 criteria of wisdom: factual knowledge, procedural knowledge, life-span contextualism, value relativism, and management of uncertainty. Contrary to most studies of cognitive aging, young and older adults did not differ. Rather, each age-cohort group received highest ratings when responding to a life dilemma matched to their own life phase. Discussed is the application of a wisdom framework to assessing therapeutic treatment goals and therapist interventions as well as global changes in client's beliefs during therapy.

    Purpose To evaluate the effect of introduction of iterative reconstruction as a mandated software upgrade on radiation dosimetry in routine clinical practice over a range of computed tomography examinations. Methods Random samples of scanning data were extracted from a centralised Picture Archiving Communication System pertaining to 10 commonly performed computed tomography examination types undertaken at two hospitals in Western Australia, before and after the introduction of iterative reconstruction. Changes in the mean dose length product and effective dose were evaluated along with estimations of associated changes to annual cancer incidence. Results We observed statistically significant reductions in the effective radiation dose for head computed tomography (22–27%) consistent with those reported in the literature. In contrast the reductions observed for non-contrast chest (37–47%); chest pulmonary embolism study (28%), chest/abdominal/pelvic study (16%) and thoracic spine (39%) computed tomography. Statistically significant reductions in radiation dose were not identified in angiographic computed tomography. Dose reductions translated to substantial lowering of the lifetime attributable risk, especially for younger females, and estimated numbers of incident cancers. Conclusion Reduction of CT dose is a priority Iterative reconstruction algorithms have the potential to significantly assist with dose reduction across a range of protocols. However, this reduction in dose is achieved via reductions in image noise. Fully realising the potential dose reduction of iterative reconstruction requires the adjustment of image factors and forgoing the noise reduction potential of the iterative algorithm. Our study has demonstrated a reduction in radiation dose for some scanning protocols, but not to the extent experimental studies had previously shown or in all protocols expected, raising questions about the extent to which iterative reconstruction achieves dose

    AIM To determine the outcome of non-investigational treatment with intravitreal bevacizumab (IVB) in neovascular age-related macular degeneration (AMD) patients. METHODS Retrospective chart review of 81 eyes with neovascular AMD followed-up for at least 12mo and received 3-monthly loading IVB injections. Re-treat was based upon the individual clinician's judgment. Best-corrected visual acuity (BCVA) and optical coherence tomography measurements of central foveal thickness outcomes were evaluated at 12, 24mo. RESULTS Eighty-one eyes (of 75 patients) completed 12mo of follow-up and 44 eyes (of 41 patients) completed 24mo of follow-up. The mean baseline logMAR BCVA significantly improved from 0.94±0.69 to 0.85±0.68 at 12mo (P<0.001) and from 0.91±0.65 to 0.85±0.60 (P=0.004) at 24mo. The proportion of eyes that lost <15 logMAR letters at 12mo was 90.1% and at 24mo was 81.8%. IVB was effective in improving visual acuity in both treatment naïve and previous photodynamic therapy (PDT)-treated subgroups. Treatment naive patients required significantly fewer injections than patients with prior PDT. Multiple regression analysis identified that poorer baseline visual acuity was associated with greater improvement in visual acuity (P=0.015). CONCLUSION Fewer injections in clinical practice may result in suboptimal visual outcomes compared with clinical trials of IVB in neovascular AMD patients. Poor baseline visual acuity and prior PDT treatment may also improve vision after IVB. The safety and durability of effect was maintained at 24mo. PMID:27158614

    The endothelial glycocalyx has a profound influence at the vascular wall on the transmission of shear stress, on the maintenance of a selective permeability barrier and a low hydraulic conductivity, and on attenuating firm adhesion of blood leukocytes and platelets. Major constituents of the glycocalyx, including syndecans, heparan sulphates and hyaluronan, are shed from the endothelial surface under various acute and chronic clinical conditions, the best characterized being ischaemia and hypoxia, sepsis and inflammation, atherosclerosis, diabetes, renal disease and haemorrhagic viral infections. Damage has also been detected by in vivo microscopic techniques. Matrix metalloproteases may shed syndecans and heparanase, released from activated mast cells, cleaves heparan sulphates from core proteins. According to new data, not only hyaluronidase but also the serine proteases thrombin, elastase, proteinase 3 and plasminogen, as well as cathepsin B lead to loss of hyaluronan from the endothelial surface layer, suggesting a wide array of potentially destructive conditions. Appropriately, pharmacological agents such as inhibitors of inflammation, antithrombin and inhibitors of metalloproteases display potential to attenuate shedding of the glycocalyx in various experimental models. Also, plasma components, especially albumin, stabilize the glycocalyx and contribute to the endothelial surface layer. Though symptoms of the above listed diseases and conditions correlate with sequelae expected from disturbance of the endothelial glycocalyx (oedema, inflammation, leukocyte and platelet adhesion, low reflow), therapeutic studies to prove a causal connection have yet to be designed. With respect to studies on humans, some clinical evidence exists for benefits from application of sulodexide, a preparation delivering precursors of the glycocalyx constituent heparan sulphate. At present, the simplest option for protecting the glycocalyx seems to be to ensure an adequate level of

    The objective of this review was to examine the effects of nursing education interventions on clinical outcomes for acute pain management in hospital settings, relating interventions to health care behavior change theory. Three databases were searched for nursing education interventions from 2002 to 2015 in acute hospital settings with clinical outcomes reported. Methodological quality was rated as strong, moderate, or weak using the Effective Public Health Practice Project Quality Assessment Tool for quantitative studies. The 12 eligible studies used varied didactic and interactive teaching methods. Several studies had weaknesses attributable to selection biases, uncontrolled confounders, and lack of blinding of outcome assessors. No studies made reference to behavior change theory in their design. Eight of the 12 studies investigated nursing documentation of pain assessment as the main outcome, with the majority reporting positive effects of education interventions on nursing pain assessment. Of the remaining studies, two reported mixed findings on patient self-report of pain scores as the key measure, one reported improvements in patient satisfaction with pain management after a nursing intervention, and one study found an increase in nurses' delivery of a relaxation treatment following an intervention. Improvements in design and evaluation of nursing education interventions are suggested, drawing on behavior change theory and emphasizing the relational, contextual, and emotionally demanding nature of nursing pain management in hospital settings.

    Whilst there is a growing evidence to support the impact of cognitive-behavioural therapy (CBT) in the treatment of adults with eating disorders, much of this evidence comes from tightly controlled efficacy trials. This study aimed to add to the evidence regarding the effectiveness of CBT when delivered in a routine clinical setting. The participants were 203 adults presenting with a range of eating disorder diagnoses, who were offered CBT in an out-patient community eating disorders service in the UK. Patients completed measures of eating disorder pathology at the start of treatment, following the sixth session, and at the end of treatment. Symptoms of anxiety, depression, and psychosocial functioning were measured pre- and post-treatment. Approximately 55% of patients completed treatment, and there were no factors that predicted attrition. There were significant improvements in eating disorder psychopathology, anxiety, depression and general functioning, with particular changes in eating attitudes in the early part of therapy. Effect sizes were medium to large for both completer and intention to treat analyses. These findings confirm that evidence-based forms of CBT can be delivered with strong outcomes in routine clinical settings. Clinicians should be encouraged to deliver evidence-based treatments when working in these settings.

  3. Organ and tissue donation in clinical settings: a systematic review of the impact of interventions aimed at health professionals

    In countries where presumed consent for organ donation does not apply, health professionals (HP) are key players for identifying donors and obtaining their consent. This systematic review was designed to verify the efficacy of interventions aimed at HPs to promote organ and tissue donation in clinical settings. CINAHL (1982 to 2012), COCHRANE LIBRARY, EMBASE (1974 to 2012), MEDLINE (1966 to 2012), PsycINFO (1960 to 2012), and ProQuest Dissertations and Theses were searched for papers published in French or English until September 2012. Studies were considered if they met the following criteria: aimed at improving HPs’ practices regarding the donation process or at increasing donation rates; HPs working in clinical settings; and interventions with a control group or pre-post assessments. Intervention behavioral change techniques were analyzed using a validated taxonomy. A risk ratio was computed for each study having a control group. A total of 15 studies were identified, of which only 5 had a control group. Interventions were either educational, organizational or a combination of both, and had a weak theoretical basis. The most common behavior change technique was providing instruction. Two sets of interventions showed a significant risk ratio. However, most studies did not report the information needed to compute their efficacy. Therefore, interventions aimed at improving the donation process or at increasing donation rates should be based on sound theoretical frameworks. They would benefit from more rigorous evaluation methods to ensure good knowledge translation and appropriate organizational decisions to improve professional practices. PMID:24628967

    Individual speech intelligibility was measured in quiet and noise for cochlear Implant recipients upgrading from the Freedom to the CP900 series sound processor. The postlingually deafened participants (n = 23) used either Nucleus CI24RE or CI512 cochlear implant, and currently wore a Freedom sound processor. A significant group mean improvement in speech intelligibility was found in quiet (Freiburg monosyllabic words at 50 dBSPL) and in noise (adaptive Oldenburger sentences in noise) for the two CP900 series SmartSound programs compared to the Freedom program. Further analysis was carried out on individual's speech intelligibility outcomes in quiet and in noise. Results showed a significant improvement or decrement for some recipients when upgrading to the new programs. To further increase speech intelligibility outcomes when upgrading, an enhanced upgrade procedure is proposed that includes additional testing with different signal-processing schemes. Implications of this research are that future automated scene analysis and switching technologies could provide additional performance improvements by introducing individualized scene-dependent settings.

    The aim of the study was to develop a real-time RT-PCR for the detection of enteroviruses (EVs) and rhinoviruses (RVs) and to assess the performance of the xTAG RVP Fast assay in comparison to a direct fluorescent assay (DFA), a real-time RT-PCR assay for the detection of respiratory syncytial virus (RSV) and human metapneumovirus (hMPV), and the EV/RV RT-PCR assay developed in this study. The performance of the RVP Fast assay was assessed in the analysis of 373 nasopharyngeal samples. For the viruses of the DFA panel, detection rates of 27.6% and 23.8% were obtained by RVP and DFA, respectively, in analysis of a set of 297 samples collected in 2009-2010. These results show statistically significant superiority of the RVP Fast assay (P=0.049). For RSV, hMPV, EV, and RV, detection rates of 48.0% and 45.2% were achieved by RVP and RT-PCR, respectively. For individual targets, increased detection of EV/RV (P=0.043) and decreased detection of influenza A virus (P=0.004) by RVP in comparison to real-time RT-PCR was observed. The results of the present study imply the need to adjust the InfA component of the RVP Fast assay to also cover the InfA(H1N1) 2009 virus.

    Often, baccalaureate nursing students initially approach a psychiatric mental health practicum with uncertainty, and even fear. They may feel unprepared for the myriad complex practice situations encountered. In addition, memories of personal painful life events may be vicariously evoked through learning about and listening to the experiences of those diagnosed with mental disorders. When faced with such challenging situations, nursing students often seek counsel from the clinical and/or classroom faculty. Pedagogic boundaries may begin to blur in the face of student distress. For the nurse educator, several questions arise: Should a nurse educator provide counseling to students? How does one best negotiate the boundaries between 'counselor', and 'caring educator'? What are the limits of a caring and professional pedagogic relation? What different knowledges provide guidance and to what differential consequences for ethical pedagogic relationships? This paper offers a comparative analysis of three philosophical stances to examine differences in key assumptions, pedagogic positioning, relationships of power/knowledge, and consequences for professional ethical pedagogic practices. While definitive answers are difficult, the authors pose several questions for consideration in discerning how best to proceed and under what particular conditions.

    Kampo-medicine has become popular in Japanese medical practice combined with western medicine. For example, Daikenchu-To for intestinal obstruction after surgical operation, Shakuyakukanzo-To and Goshajinki-Gan for anti-cancer agents-induced neuropathy, and Yokkan-San for behavioral psychological symptoms of dementia are alternatively used in addition to conventional treatments in Japan. However, combined use of Kampo-medicine and western medicine may cause unexpected adverse events including undesirable drug-drug interactions because Kampo-medicine was not originally developed to be used with western medicine. Although adverse effects of Kampo-medicine are rare compared with those of western medicine, severe events such as liver dysfunction and interstitial pneumonia have been reported in increasing trends. Medical staff including pharmacists, therefore, should be aware of the onset of adverse events before the patients' symptoms become severe. Several adverse effects are caused by chemical constituents such as glycyrrhizin in licorice for pseudoaldosteronism and geniposide in Gardeniae fructus for mesenteric phlebosclerosis. To understand the adverse effects of Kampo-medicine, pharmacists should learn trends in current medication as well as pharmacology and toxicology of the chemical constituents in pharmacognosy. These issues should also be addressed in educational materials for students of clinical pharmacy and pharmacy practice.

    The current study explored the clinical feasibility and costs of embedding three different intensive service delivery models for aphasia treatment (computer, group therapy, and therapy with a speech pathology therapy assistant) within three sub-acute facilities. The study employed a two cohort comparison design, with the first cohort (n = 22) receiving the standard service of treatment currently offered. This treatment was delivered by a speech-language pathologist and involved on average 3 hours of treatment/week over 8 weeks. Participants in the second cohort (n = 31) received one of the three intensive treatment models providing up to 9 hours of therapy/week for 11 weeks. Organizational data was collected throughout treatment, with participant, caregiver, and clinician satisfaction with the intensive models also being measured. Participants completed the spoken language production sub-tests and the Disability Questionnaire of the Comprehensive Aphasia Test (CAT) pre- and post-treatment. All intensive models yielded high participant attendance, satisfaction, and significant improvements to the CAT sub-tests. The pro-rata cost of providing treatment per hour per client for the computer and group therapy models was found to be ˜ 30% cheaper compared to the standard service. The outcomes support the potential feasibility of embedding the different models into sub-acute facilities to enhance client access to intensive treatment for aphasia.

    Achieving hemostasis is a crucial focus of clinicians working in surgical and trauma settings. Topical hemostatic agents-including mechanical hemostats, active hemostats, flowable hemostats, and fibrin sealants-are frequently used in efforts to control bleeding, and new options such as hemostatic dressings, initially used in combat situations, are increasingly being used in civilian settings. To achieve successful hemostasis, a number of vital factors must be considered by surgeons and perioperative nurses, such as the size of the wound; bleeding severity; and the efficacy, possible adverse effects, and method of application of potential hemostatic agents. Understanding how and when to use each of the available hemostatic agents can greatly affect clinical outcomes and help to limit the overall cost of treatment.

    Only a small minority of mobile healthcare technologies that have been successful in pilot studies have subsequently been integrated into healthcare systems. Understanding the reasons behind this discrepancy is crucial if such technologies are to be adopted. We believe that the mismatch is due to a breakdown in the relation between technical soundness of the original mobile health (mHealth) device design, and integration into healthcare provision workflows. Quantitative workflow modelling provides an opportunity to test this hypothesis. In this paper we present our current progress in developing a clinical workflow model for mobile eye assessment in low-income settings. We test the model for determining the appropriateness of design parameters of a mHealth device within this workflow, by assessing their impact on the entire clinical workflow performance.

    Parkinson's disease (PD) is the second most common neurodegenerative disorder, affecting 5% of the elderly population. PD diagnosis is still based on the identification of neuromotor symptoms although nonmotor manifestations emerge years prior to diagnosis. The discovery of biomarkers at the earliest stages of PD is of extreme interest. miRNAs have been considered potential biomarkers for neurodegenerative diseases, but only a limited number have been found to be PD related. This review focuses on the current findings in the field of circulating miRNAs in PD and the challenges surrounding clinical utility and validation. We briefly describe the more established circulating biomarkers in PD and provide a more thorough review of miRNAs differentially expressed in PD. We highlight their potential for being considered as biomarkers for diagnosis while emphasizing the challenges for adequate validation of the findings and how miRNAs can be envisioned in a clinical setting satisfying regulatory bodies.

    Core clinical skills acquisition is an essential component of undergraduate medical and midwifery education. Although interprofessional education is an increasingly common format for learning efficient teamwork in clinical medicine, its value in undergraduate education is less clear. We present a collaborative effort from the medical and midwifery schools of Monash University, Melbourne, towards the development of an educational package centred around a core skills-based workshop using low fidelity simulation models in an interprofessional setting. Detailed feedback on the package was positive with respect to the relevance of the teaching content, whether the topic was well taught by task trainers and simulation models used, pitch of level of teaching and perception of confidence gained in performing the skill on a real patient after attending the workshop. Overall, interprofessional core skills training using low fidelity simulation models introduced at an undergraduate level in medicine and midwifery had a good acceptance.

    Clinical pharmacology as an interdisciplinary science is unique in its capacity and the diversity of the methods and approaches it can provide to derive dosing recommendations in various subpopulations. This article illustrates cases where an integrated clinical pharmacology approach was used to derive dosing recommendations for psychiatry drugs within regulatory settings. The integrated approach is based on the view that once a drug is shown to be effective in the general population, it is reasonable to take into consideration other relevant findings and the use of alternative scientific tools and analysis to derive dosing recommendations in specific populations. The method provides useful means to solve the challenges of the paucity of available data and lead to clear dosing instructions. This in turn expands the benefits of any given drug to all individuals in which the drug is likely to be effective.

    Background There is little evidence to guide the establishment of treatment goals for moderate-to-severe psoriasis in the clinical setting. Objective To compare Dermatology Life Quality Index scores and prescription topical medication use between patients with clear versus almost clear skin. Methods Multicenter cross-sectional study of 97 patients with clear skin and 441 patients with almost clear skin receiving current systemic therapy or phototherapy for a primary indication of plaque psoriasis evaluated at one of ten US outpatient dermatology sites participating in the Dermatology Clinical Effectiveness Research Network. Results In adjusted analyses, patients with clear versus almost clear skin were more likely to report no impact of psoriasis on quality of life (relative risk 1.60; 95% confidence interval, 1.37–1.86). Patients with clear versus almost clear skin were also more likely to report no prescription topical medication use in the preceding week (relative risk 2.08; 95% confidence interval, 1.73–2.49). Limitations Cross-sectional design prohibits longitudinal assessment of outcomes. Conclusions and Relevance Clinically important differences in quality of life and prescription topical medication use exist between patients with clear versus almost clear skin. Collectively, our results indicate that achievement of clear skin may be an important clinical distinction among patients with moderate-to-severe psoriasis. PMID:24928705

    The elderly population in the United States is increasing exponentially in tandem with risk for frailty. Frailty is described by a clinically significant state where a patient is at risk for developing complications requiring increased assistance in daily activities. Frailty syndrome studied in geriatric patients is responsible for an increased risk for falls, and increased mortality. In efforts to prepare for and to intervene in perioperative complications and general frailty, a universal scale to measure frailty is necessary. Many methods for determining frailty have been developed, yet there remains a need to define clinical frailty and, therefore, the most effective way to measure it. This article reviews six popular scales for measuring frailty and evaluates their clinical effectiveness demonstrated in previous studies. By identifying the most time-efficient, criteria comprehensive, and clinically effective scale, a universal scale can be implemented into standard of care and reduce complications from frailty in both non-surgical and surgical settings, especially applied to the perioperative surgical home model. We suggest further evaluation of the Edmonton Frailty Scale for inclusion in patient care. PMID:27493935

    Carrier screening for certain diseases is recommended by major medical and Ashkenazi Jewish (AJ) societies. Most carrier screening panels test only for common, ethnic-specific variants. However, with formerly isolated ethnic groups becoming increasingly intermixed, this approach is becoming inadequate. Our objective was to develop a rigorous process to curate all variants, for relevant genes, into a database and then apply stringent clinical validity classification criteria to each in order to retain only those with clear evidence for pathogenicity. The resulting variant set, in conjunction with next-generation DNA sequencing (NGS), then affords the capability for an ethnically diverse, comprehensive, highly specific carrier-screening assay. The clinical utility of our approach was demonstrated by screening a pan-ethnic population of 22,864 individuals for Bloom syndrome carrier status using a BLM variant panel comprised of 50 pathogenic variants. In addition to carriers of the common AJ founder variant, we identified 57 carriers of other pathogenic BLM variants. All variants reported had previously been curated and their clinical validity documented, or were of a type that met our stringent, preassigned validity criteria. Thus, it was possible to confidently report an increased number of Bloom’s syndrome carriers compared to traditional, ethnicity-based screening, while not reducing the specificity of the screening due to reporting variants of unknown clinical significance.

    The burden of chronic disease is greater in individuals with dementia, a patient group that is growing as the population is aging. The cornerstone of optimal management of chronic disease requires effective patient self-management. However, this is particularly challenging in older persons with a comorbid diagnosis of dementia. The impact of dementia on a person's ability to self-manage his/her chronic disease (eg, diabetes mellitus or heart failure) varies according to the cognitive domain(s) affected, severity of impairment and complexity of self-care tasks. A framework is presented that describes how impairment in cognitive domains (attention and information processing, language, visuospatial ability and praxis, learning and memory and executive function) impacts on the five key processes of chronic disease self-management. Recognizing the presence of dementia in a patient with chronic disease may lead to better outcomes. Patients with dementia require individually tailored strategies that accommodate and adjust to the individual and the cognitive domains that are impaired, to optimize their capacity for self-management. Management strategies for clinicians to counter poor self-management due to differentially impaired cognitive domains are also detailed in the presented framework. Clinicians should work in collaboration with patients and care givers to assess a patient's current capabilities, identify potential barriers to successful self-management and make efforts to adjust the provision of information according to the patient's skill set. The increasing prevalence of age-related chronic illness along with a decline in the availability of informal caregivers calls for innovative programs to support self-management at a primary care level.

    Background: Childhood bacterial meningitis is a neurologic emergency that continues to kill and maims children particularly in developing countries with poor immunization coverage. Objective: This study set out to assess the hospital incidence, pattern of presentation, etiologic agents, outcome and determinants of mortality among the children admitted with bacterial meningitis at the Wesley Guild Hospital (WGH), Ilesa. Patients and Methods: We carried out a retrospective review of admitted cases of bacterial meningitis in children aged one month to 15 years at the WGH, Ilesa over a three year period by looking at the hospital records. Factors in the history and examinations were compared among survivors and those that died to determine factors significantly associated with mortality in these children. Results: Eighty-one (5.5%) of the 1470 childhood admissions during the study period had bacterial meningitis. Male preponderance was observed and two-thirds of the children were infants. More cases were admitted during the wet rainy season than during the dry harmattan season. Haemophilus influenzae type B and Streptococcus pneumoniae were the leading etiologic agents and ciprofloxacin and ceftriaxone adequately cover for these organisms. Twenty-two (27.2%) of the 81 children died, while 34 (42.0%) survived with neurologic deficits. Children with multiple seizures, coma, neck retraction, hyponatremia, hypoglycorrhachia, turbid CSF as well as Gram positive meningitis at presentation were found to more likely to die (P < 0.05). None of these factors however independently predict mortality. Conclusion: Childhood bacterial meningitis often results in death and neurologic deficit among infants and young children admitted at the WGH, Ilesa. Children diagnosed with meningitis who in addition had multiple seizures, neck retraction and coma at presentation are at increased risk of dying. PMID:26752902

    The aim of this study was to assess the prevalence clinical presentation, and impact on outcome of late hepatic artery thrombosis (HAT) after OLT. We also sought risk factors other than technical problems that predispose to the pathogenesis of late HAT among 178 OLT performed from 1999 to 2002. Late HAT was diagnosed using Doppler ultrasonography and arteriography. Late HAT was observed in nine patients (3.8%), all of whom had experienced chronic HCV infection. Median time to HAT diagnosis was 4.88 months after OLT. Mean follow-up time was 40.25 months. Recipient age ranged from 30 to 61 years and median donor age, 28 years. Mean warm ischemia time was 63 minutes and mean cold ischemia time, 660 minutes. All of our study group were cigarette smokers. Postoperative CMV infection, presenting with hepatitis, had been treated in 55.6%. Before the diagnosis of HAT more than one episode of acute cellular rejection had been observed in six patients (55.6%) and 44.5% had chronic rejection. The diagnosis of CR was established after the diagnosis of HAT in all cases. Recurrence of HCV infection was histologically documented in 44.5%. Only one patient experienced graft loss (77 months after OLT). Six of nine patients had biliary complications, treated either by endoscopic stenting or by surgical drainage. Two patients were asymptomatic. In conclusion, late HAT shows a benign presentation that has no impact on graft survival. Possible risk factors have yet to be defined by multicenter trials.

    Food insecurity is a serious health concern among children in the United States with 15.3 million children living in food insecure households. The American Academy of Pediatrics recommends that pediatricians screen for food insecurity at health maintenance visits as identifying children at risk is a crucial step in the amelioration of food insecurity. Two surveys were administered in a Midwest pediatric clinic. A cross-sectional survey was electronically distributed to pediatric providers to assess perceptions of food insecurity among patients, provider readiness to conduct food security screenings, and barriers to conducting those screenings. A cross-sectional caregiver survey was administered to assess demographics, household food security status, participation in nutrition assistance programs, and barriers to getting enough food to eat. Descriptive statistics and odds ratios were calculated. Eighty-eight percent of physicians believe that food insecurity is a challenge for some of their patients. Only 15 % of providers reported screening for food insecurity, while 80 % were willing to screen. Physicians were most concerned with knowing how to handle a positive screen. Among caregivers, 57 % screened positive for food insecurity. Those experiencing food insecurity were more likely to be non-white, participate in SNAP and to feel discomfort towards the idea of talking to a doctor or nurse about food needs. Caregivers reporting food insecurity were significantly less likely to have a personal vehicle. Effective food insecurity screening requires addressing caregiver and health provider barriers in order to increase the likelihood of identifying households most at risk.

    To review the interaction between melatonin and the dopaminergic system in the hypothalamus and striatum and its potential clinical use in dopamine-related disorders in the central nervous system. Medline-based search on melatonin-dopamine interactions in mammals. Melatonin. the hormone produced by the pineal gland at night. influences circadian and seasonal rhythms, most notably the sleep-wake cycle and seasonal reproduction. The neurochemical basis of these activities is not understood yet. Inhibition of dopamine release by melatonin has been demonstrated in specific areas of the mammalian central nervous system (hypothalamus, hippocampus, medulla-pons, and retina). Antidopaminergic activities of melatonin have been demonstrated in the striatum. Dopaminergic transmission has a pivotal role in circadian entrainment of the fetus, in coordination of body movement and reproduction. Recent findings indicate that melatonin may modulate dopaminergic pathways involved in movement disorders in humans. In Parkinson patients melatonin may, on the one hand, exacerbate symptoms (because of its putative interference with dopamine release) and, on the other, protect against neurodegeneration (by virtue of its antioxidant properties and its effects on mitochondrial activity). Melatonin appears to be effective in the treatment of tardive dyskinesia. a severe movement disorder associated with long-term blockade of the postsynaptic dopamine D2 receptor by antipsychotic drugs in schizophrenic patients. The interaction of melatonin with the dopaminergic system may play a significant role in the nonphotic and photic entrainment of the biological clock as well as in the fine-tuning of motor coordination in the striatum. These interactions and the antioxidant nature of melatonin may be beneficial in the treatment of dopamine-related disorders.

    Background and Purpose: In vitro radiation doses of below 0.5 Gy have been shown to be more effective than higher doses per unit dose in killing clonogenic cells of many epithelial tumor cell lines. This phenomenon is known as low-dose hyperradiosensitivity. Preclinical studies have now suggested that there is synergism between chemotherapy and low-dose fractionated radiotherapy (LD-FRT). To test the clinical efficacy of this approach, we prospectively evaluated concurrent palliative chemotherapy and LD-FRT in patients with various types of epithelial tumors. Methods and Materials: Patients suffering from relapses or metastases of epithelial tumors were scheduled to receive concurrent LD-FRT (two fractions of 0.4 Gy per day) and chemotherapy. Radiologic assessments were performed after three cycles of chemotherapy plus LD-FRT. Results: Between June 2006 and October 2007, 12 patients with lung cancer, 7 patients with head-and-neck tumors, 2 patients with breast cancer, and 1 patient with esophageal carcinoma, for a total patient population of 22, underwent concomitant LD-FRT and chemotherapy. All patients but 3 (86%) had received previous treatments for their cancer. The median total dose of LD-FRT delivered was 800 cGy (range, 320-1280 cGy). The overall response rate was 45% (42% in previously treated patients). Grade 3-4 hematologic toxicities (Radiation Therapy Oncology Group ratings) were observed in 2 patients. At a median follow-up of 6.5 months, however, no local toxicity was observed. Conclusion: In our experience, concurrent LD-FRT and chemotherapy was well tolerated. Because the response rate seems promising, prospective Phase II studies of the strategy are now under way.

    This study aimed to apply the recently proposed Oslo hand osteoarthritis magnetic resonance imaging (MRI) scoring system to evaluate MRI findings in a cohort of patients affected by long-standing erosive hand osteoarthritis (EHOA). Eleven female EHOA patients (median 59 [interquartile range 62-52] years, disease duration 9.5 [interquartile range 13-3.75] years) underwent MRI (1.5 T) of the dominant hand, and synovitis, bone marrow lesions (BMLs), joint space narrowing, osteophytes, cysts, malalignment, and erosions were scored using the Oslo scoring system. Intra- and inter-reader reliability were assessed. The patients also underwent X-ray examination, and bone features were evaluated using the same scoring system. Pain and tenderness were assessed during a physical examination. Spearman's non-parametric test was used to analyze the correlations between variables. MRI intra- and inter-reader reliability were found between good and moderate for many features. No statistical differences were found between the radiographs and MRI with regard to detection of JSN, malalignment, and bone erosions. Synovitis was detected in 39.8 % of the 80 joints examined (in a mild form in 80 %), erosions were found in 51.1 %, and BMLs were identified in 20.5 and 23.9 % at the distal and the proximal side, respectively. BMLs at both the proximal and distal ends were correlated with tender joints (BML distal p = 0.0013, BML proximal p = 0.012). The presence of synovitis was correlated with tenderness (p = 0.004) and erosions at both the distal and proximal joints (p = 0.004). The presence of erosions correlated with tender joints (p < 0.01) and the mean visual analog scale (VAS) score (distal p = 0.03, proximal p = 0.01). Synovitis and BMLs were correlated with clinical symptoms in our patients affected with long-standing EHOA.

    The estimated prevalence of hepatitis C virus (HCV) infection in the US is 1.8 %. Data are limited on the clinical profile of the disease at first presentation and dynamic follow-up of ALT level, especially in publicly-funded patients. This information is critical for optimal management of these patients. The present study is aimed to assess the clinical profiles of chronic hepatitis C (CHC) at first presentation and clinical implication of dynamic follow-up of ALT level in a county medical center setting. A total of 294 patients were selected from the population consecutively evaluated in the Hepatitis Clinic at Los Angeles County-USC Medical Center between Jan. 1990 and Dec. 1998. Ethnicity of the patients was Hispanics-49.0%, Caucasian-28.6%, African American-13.6%, and Asian-8.8%. Risk factors were identifiable in 84.0% of patients, and injection drug use (IDU) represented the leading risk factor for HCV acquisition (47.4%). History of alcoholism was present in 39.1%. The initial clinical diagnoses were chronic hepatitis 76.9%; compensated cirrhosis 20.4%; and decompensated cirrhosis 2.7%. Elevation of ALT, alpha fetoprotein (AFP), ferritin, and anti-nuclear antibody (ANA) titer were seen in 219/294 (74.5%), 60/194 (30.9%), 20/83 (24.1%), and 35/97 (36.1%) patients, respectively. Anti-HBc (total) test was positive in 65/129 (50.5%) patients. The presence of cirrhosis was significantly associated with age greater than 55 years at entry, female gender, non-African American ethnicity, history of transfusion, lower level of albumin and elevated level of AFP. Longitudinal observation of ALT changes in 178 patients who had neither evidence of cirrhosis at entry nor received interferon treatment showed persistently normal, intermittently or persistently elevated ALT level in 15.2%, 38.3%, and 46.6% patients, respectively. The frequency of developing clinical evidence of cirrhosis during follow-up was significantly higher in patients with persistently (16.0%) or

    Objective: To simultaneously improve patient care processes and clinical research activities by starting a hypothesis-driven reorganization trajectory mimicking the rigorous methodology of a prospective clinical trial. Methods: The design of this reorganization trajectory was based on the model of a prospective trial. It consisted of (1) listing problems and analysing their potential causes, (2) defining interventions, (3) defining end points and (4) measuring the effect of the interventions (i.e. at baseline and after 1 and 2 years). The primary end point for patient care was the number of organizational root causes of incidents/near incidents; for clinical research, it was the number of patients in trials. There were several secondary end points. We analysed the data using two sample z-tests, χ2 test, a Mann–Whitney U test and the one-way analysis of variance with Bonferroni correction. Results: The number of organizational root causes was reduced by 27% (p < 0.001). There was no effect on the percentage of patients included in trials. Conclusion: The reorganizational trajectory was successful for the primary end point of patient care and had no effect on clinical research. Some confounding events hampered our ability to draw strong conclusions. Nevertheless, the transparency of this approach can give medical professionals more confidence in moving forward with other organizational changes in the same way. Advances in knowledge: This article is novel because managerial interventions were set up similarly to a prospective clinical trial. This study is the first of its kind in radiotherapy, and this approach can contribute to discussions about the effectiveness of managerial interventions. PMID:25679320

    The 20th anniversary of the Journal of Clinical Psychology in Medical Settings is celebrated by highlighting the scientist-practitioner philosophy on which it was founded. The goal of the Journal-to provide an outlet for evidence-based approaches to healthcare that underscore the important scientific and clinical contributions of psychology in medical settings-is discussed. The contemporary relevance of this approach is related to the current implementation of the Patient Protection and Affordable Care and its focus on accountability and the development of an interprofessional healthcare workforce; both of which have been foci of the Journal throughout its history and will continue to be so into the future. Several recommendations of future topic areas for the Journal to highlight regarding scientific, practice, policy, and education and training in professional health service psychology are offered. Successfully addressing these topics will support the growth of the field of psychology in the ever evolving healthcare system of the future and continue ensure that the Journal is a key source of professional information in health service psychology.

    Virtual Fracture Clinics (VFCs) are an alternative to the conventional fracture clinics, to manage certain musculoskeletal injuries. This has recently been reported as a safe, cost-effective and efficient care model. As demonstrated at vanguard sites in the United Kingdom, VFCs can enhance patient care by standardising treatment and reducing outpatient appointments. This project demonstrates how a Quality Improvement approach was applied to introduce VFCs in the District General Hospital setting. We demonstrate how undertaking Process Mapping, Driver Diagrams, and Stakeholder Analysis can assist implementation. We discuss Whole Systems Measures applicable to VFCs, to consider how robust and specific data collection can progress this care model. Three Plan-Do-Study-Act cycles led to a change in practice over a 21-month period. Our target for uptake of new patients seen in VFCs within 6 months of starting was set at 50%. It increased from 0% to 56.1% soon after introduction, and plateaued at an average of 56.4% in the six-months before the end of the study period. Careful planning, frequent monitoring, and gathering feedback from a multidisciplinary team of varying seniority, were the important factors in transitioning to, and sustaining, a successful VFC model.

    Neuropsychiatric symptoms (NPS) of dementia include aggression, agitation, depression, anxiety, delusions, hallucinations, apathy, and disinhibition. NPS affect dementia patients nearly universally across dementia stages and etiologies. They are associated with poor patient and caregiver outcomes, including increased health care utilization, excess morbidity and mortality, and earlier nursing home placement, as well as caregiver stress, depression and reduced employment. There are no FDA-approved medications for NPS, but it is a common clinical practice to use psychotropic medications such as antipsychotics, to control symptoms; however, antipsychotics show only modest efficacy in improving NPS and have significant risks for patients, including side effects and mortality. Nonpharmacologic treatments are considered first-line by multiple medical bodies and expert consensus, as they show evidence for efficacy and have limited potential for adverse effects. Ideally, nonpharmacological management of NPS in clinical settings occurs in multidisciplinary teams, where occupational therapists play an important collaborative role in the care of the person with dementia. Our group has articulated an evidence-informed structured approach to the management of NPS that can be integrated into diverse practice settings and used by providers of various disciplines. The "DICE" (Describe, Investigate, Create, and Evaluate) approach is inherently patient- and caregiver-centered, as patient and caregiver concerns are integral to each step of the process. DICE offers a clinical reasoning approach through which providers can more efficiently and effectively choose optimal treatment plans. The purpose of this paper is to describe the role of the occupational therapy in using the DICE approach for NPS management.

    Infrastructure for conducting neurological research in resource-limited settings (RLS) is limited. The lack of neurological and neuropsychological (NP) assessment and normative data needed for clinical interpretation impedes research and clinical care. Here, we report on ACTG 5271, which provided neurological training of clinical site personnel and collected neurocognitive normative comparison data in diverse settings. At ten sites in seven RLS countries, we provided training for NP assessments. We collected normative comparison data on HIV- participants from Brazil (n = 240), India (n = 480), Malawi (n = 481), Peru (n = 239), South Africa (480), Thailand (n = 240), and Zimbabwe (n = 240). Participants had a negative HIV test within 30 days before standardized NP exams were administered at baseline and 770 at 6 months. Participants were enrolled in eight strata, gender (female and male), education (<10 and ≥10 years), and age (<35 and ≥35 years). Of 2400 enrolled, 770 completed the 6-month follow-up. As expected, significant between-country differences were evident in all the neurocognitive test scores (p < 0.0001). There was variation between the age, gender, and education strata on the neurocognitive tests. Age and education were important variables for all tests; older participants had poorer performance, and those with higher education had better performance. Women had better performance on verbal learning/memory and speed of processing tests, while men performed better on motor tests. This study provides the necessary neurocognitive normative data needed to build infrastructure for future neurological and neurocognitive studies in diverse RLS. These normative data are a much-needed resource for both clinicians and researchers.

    Cerebral microbleeds (CMBs) have emerged as a new imaging marker of small vessel disease. Composed of hemosiderin, CMBs are paramagnetic and can be detected with MRI sequences sensitive to magnetic susceptibility (typically, gradient recalled echo T2* weighted images). Nevertheless, their identification remains challenging on T2* magnitude images because of confounding structures and lesions. In this context, T2* phase image may play a key role in better characterizing CMBs because of its direct relationship with local magnetic field variations due to magnetic susceptibility difference. To address this issue, susceptibility-based imaging techniques were proposed, such as Susceptibility Weighted Imaging (SWI) and Quantitative Susceptibility Mapping (QSM). But these techniques have not yet been validated for 2D clinical data in multicenter settings. Here, we introduce 2DHF, a fast 2D phase processing technique embedding both unwrapping and harmonic filtering designed for data acquired in 2D, even with slice-to-slice inconsistencies. This method results in internal field maps which reveal local field details due to magnetic inhomogeneity within the region of interest only. This technique is based on the physical properties of the induced magnetic field and should yield consistent results. A synthetic phantom was created for numerical simulations. It simulates paramagnetic and diamagnetic lesions within a 'brain-like' tissue, within a background. The method was evaluated on both this synthetic phantom and multicenter 2D datasets acquired in standardized clinical setting, and compared with two state-of-the-art methods. It proved to yield consistent results on synthetic images and to be applicable and robust on patient data. As a proof-of-concept, we finally illustrate that it is possible to find a magnetic signature of CMBs and CMCs on internal field maps generated with 2DHF on 2D clinical datasets that give consistent results with CT-scans in a subsample of 10 subjects

    There has been limited research investigating the conceptual development of rehabilitation in speech-language pathology (SLP) students. The aim of this study was to describe SLP students' understanding of rehabilitation following completion of a clinical practicum in a rehabilitation setting. This study was conducted using a qualitative approach according to grounded theory methodology. Semi-structured interviews were conducted with 10 SLP students who had completed a practicum in a rehabilitation setting. Interview data analysis revealed the emergence of five axial categories. Clients becoming teachers was identified as the core category, as the notion that clients were fundamental to students' understanding of rehabilitation occurred reliably throughout the data and related to all other categories. A theoretical model was proposed that demonstrated successive levels of support to students in the acquisition of their understanding of rehabilitation on practicum. Students' understanding of rehabilitation was derived from client-related interactions and factors experienced on practicum in rehabilitation settings. Rehabilitation practicum provided students with a rich and complex learning environment that may facilitate the development of the "core skills" identified for rehabilitation practice.

    Introduction Identification of yeast isolated from clinical specimens to the species level has become increasingly important. Ever-increasing numbers of immuno-suppressed patients, a widening range of recognized pathogens, and the discovery of resistance to antifungal drugs are contributing factors to this necessity. Material and methods A total of 487 yeast strains were studied for the primary isolation and presumptive identification, directly from clinical specimen. Efficacy of CHROMagar Candida has been evaluated with conventional methods including morphology on Corn meal–tween 80 agar and biochemical methods by using API 20 C AUX. Results The result of this study shows that CHROMagar Candida can easily identify three species of Candida on the basis of colonial color and morphology, and accurately differentiate between them i.e. Candida albicans, Candida tropicalis, and Candida krusei. The specificity and sensitivity of CHROMagar Candida for C. albicans calculated as 99%, for C. tropicalis calculated as 98%, and C. krusei it is 100%. Conclusion The data presented supports the use of CHROMagar Candida for the rapid identification of Candida species directly from clinical specimens in resource-limited settings, which could be very helpful in developing appropriate therapeutic strategy and management of patients.

    Faced with the challenge of meeting the wide degree of post-discharge needs in their trauma population, the University of Pittsburgh Medical Center (UPMC) developed a non-physician-led interprofessional team to provide follow-up care at its UPMC Falk Trauma Clinic. We assessed this model of care using a survey to gauge team member perceptions of this model, and used clinic visit documentation to apply a novel approach to assessing how this model improves the care received by clinic patients. The high level of perceived team performance and cohesion suggests that this model has been successful thus far from a provider perspective. Patients are seen most frequently by audiologists, while approximately half of physical therapy and speech language therapy consults generate a new therapy referral, which is interpreted as a potential change in the patient's care trajectory. The broader message of this analysis is that a collaborative, non-hierarchical team model incorporating rehabilitative specialists, who often operate independently of one another, can be successful in this setting, where patients appear to have a strong and previously under-attended need for rehabilitative intervention.

  17. Precise definitions of some terminology for longitudinal clinical trials: subjects, patient populations, analysis sets, intention to treat, and related terms.

    Biostatisticians recognize the importance of precise definitions of technical terms in randomized controlled clinical trial (RCCT) protocols, statistical analysis plans, and so on, in part because definitions are a foundation for subsequent actions. Imprecise definitions can be a source of controversies about appropriate statistical methods, interpretation of results, and extrapolations to larger populations. This paper presents precise definitions of some familiar terms and definitions of some new terms, some perhaps controversial. The glossary contains definitions that can be copied into a protocol, statistical analysis plan, or similar document and customized. The definitions were motivated and illustrated in the context of a longitudinal RCCT in which some randomized enrollees are non-adherent, receive a corrupted treatment, or withdraw prematurely. The definitions can be adapted for use in a much wider set of RCCTs. New terms can be used in place of controversial terms, for example, subject. We define terms specifying a person's progress through RCCT phases and that precisely define the RCCT's phases and milestones. We define terms that distinguish between subsets of an RCCT's enrollees and a much larger patient population. 'The intention-to-treat (ITT) principle' has multiple interpretations that can be distilled to the definitions of the 'ITT analysis set of randomized enrollees'. Most differences among interpretations of 'the' ITT principle stem from an RCCT's primary objective (mainly efficacy versus effectiveness). Four different 'authoritative' definitions of ITT analysis set of randomized enrollees illustrate the variety of interpretations. We propose a separate specification of the analysis set of data that will be used in a specific analysis. Copyright © 2016 John Wiley & Sons, Ltd.

    Background To our knowledge, no reliable clinical prediction rule (CPR) for identifying bacteremia in hemodialysis (HD) patients has been established. The aim of this study was to develop a CPR for bacteremia in maintenance HD patients visiting the outpatient department. Methods This multicenter cohort study involved consecutive maintenance HD patients who visited the outpatient clinic or emergency room of seven Japanese institutions between August 2011 and July 2013. The outcome measure was bacteremia diagnosed based on the results of blood cultures. The candidate predictors for bacteremia were extracted through a literature review. A CPR for bacteremia was developed using a coefficient-based multivariable logistic regression scoring method, and calibration was performed. The test performance was then assessed for the CPR. Results Of 507 patients eligible for the study, we analyzed the 293 with a complete dataset for candidate predictors. Of these 293 patients, 48 (16.4%) were diagnosed with bacteremia. At the conclusion of the deviation process, body temperature ≥ 38.3°C, heart rate ≥ 125 /min, C-reactive protein ≥ 10 mg/dL, alkaline phosphatase >360 IU/L, and no prior antibiotics use within the past week were retained and scored. The CPR had a good fit for the model on calibration. The AUC of the CPR was 0.76, and for score CPR ≥ 2, the sensitivity and specificity were 89.6% and 51.4%, respectively. Conclusions We established a simple CPR for bacteremia in maintenance HD patients using routinely obtained clinical information in an outpatient setting. This model may facilitate more appropriate clinical decision making. PMID:28081211

    With advances in the care of HIV-positive pregnant women, the likelihood of perinatal transmission is now less than 1%. In resource-rich settings women are instructed to abstain from breastfeeding, as studies have shown that breastfeeding increases the likelihood of infant acquisition of HIV. As practitioners caring for HIV-positive parents, we are now facing growing tension about the complex issues that inform decisions about infant feeding. In the face of changing guidelines and global immigration patterns, simply telling women that breastfeeding is contraindicated may no longer be good enough. We must fully open the lines of communication regarding this important and evolving issue. This commentary will review the clinical, social and cultural considerations that impact decisions regarding infant feeding in the context of HIV.

    Overweight children are at an increased risk of becoming obese adults, which may lead to shorter life expectancies in the current generation of children as compared to their parents. Furthermore, being an overweight child has a negative psycho-social impact. We consider obesity in children and adolescents a chronic illness, which is in line with the American Medical Society. We summarize the evidence for the efficacy of a combination of diet, physical activity and behavior-focused interventions in a family-based setting. The present guidelines propose a multidisciplinary service implemented as a "chronic care model" based on "best clinical practice" inspired by an American expert committee and the daily practice of The Children's Obesity Clinic at Copenhagen University Hospital Holbaek. Children and adolescents should be referred for examination and treatment in a pediatric setting when BMI corresponds to an isoBMI of minimum 30 or BMI corresponds to an isoBMI of 25 and complex obesity is suspected. Obtaining a thorough medical history is pivotal. We propose a structured interview to ensure collection of all relevant information. We recommend physical examination focused on BMI, waist circumference, growth, pubertal stage, blood pressure, neurology and skin and provide comprehensive paraclinical investigations for obesity and obesity related conditions. Treatment of obesity in children and adolescents is fully dependent on the combined effort of the entire family. This cannot be overemphasized! The main principle of the treatment is developing an individual detailed plan for every patient to reduce caloric intake whilst increasing physical activity, leaving no ambiguity with the recommendations.

    Autism spectrum disorder is a complex neurodevelopmental disorder, which is accompanied by differences in brain anatomy, functioning and brain connectivity. Due to its neurodevelopmental character, and the large phenotypic heterogeneity among individuals on the autism spectrum, the neurobiology of autism spectrum disorder is inherently difficult to describe. Nevertheless, significant progress has been made in characterizing the neuroanatomical underpinnings of autism spectrum disorder across the human life span, and in identifying the molecular pathways that may be affected in autism spectrum disorder. Moreover, novel methodological frameworks for analyzing neuroimaging data are emerging that make it possible to characterize the neuroanatomy of autism spectrum disorder on the case level, and to stratify individuals based on their individual phenotypic make up. While these approaches are increasingly more often employed in the research setting, their applicability in the clinical setting remains a vision for the future. The aim of the current review is to (1) provide a general overview of recent structural neuroimaging findings examining the neuroanatomy of autism spectrum disorder across the human life span, and in males and females with the condition, (2) highlight potential neuroimaging (bio)markers that may in the future be used for the stratification of autism spectrum disorder individuals into biologically homogeneous subgroups and (3) inform treatment and intervention strategies.

    Purpose: To examine the organizational design features that were consistently associated in 2010 with high levels of patient enrollment onto National Cancer Institute (NCI) cancer treatment trials among the oncology practices and hospitals participating in the NCI Community Clinical Oncology Program (CCOP). Methods: Fuzzy-set qualitative comparative analysis was used to identify the recipes (ie, combinations of organizational design features) that CCOPs used to achieve high levels of patient enrollment onto NCI treatment trials in 2010. Four organizational design features were examined: number of open treatment trials with at least one patient enrolled, number of newly diagnosed patients with cancer, number of CCOP-affiliated physicians, and number of CCOP-affiliated hospitals or practices where patient enrollment could occur. Data were obtained from NCI data systems and CCOP grant progress reports. Results: Two recipes were consistently associated with high levels of patient enrollment onto NCI treatment trials in 2010: having many open treatment trials and many new patients with cancer, and having many open treatment trials and many affiliated hospitals or practices. Together, these recipes accounted for nearly two thirds of CCOP membership in the high-performance set in 2010. Conclusion: No single organizational design feature, by itself, was consistently associated with high levels of patient enrollment onto NCI treatment trials in 2010. Having a large menu of active treatment trials may be necessary to achieve high–patient enrollment performance, but this is not sufficient unless combined with either large patient volume or many participating sites.

    There remains a need for objective and cost-effective approaches capable of diagnosing early-stage disease in point-of-care clinical settings. Given an increasingly ageing population resulting in a rising prevalence of chronic diseases, the need for screening to facilitate the personalising of therapies to prevent or slow down pathology development will increase. Such a tool needs to be robust but simple enough to be implemented into clinical practice. There is interest in extracting biomarkers from biofluids (e.g., plasma or serum); techniques based on vibrational spectroscopy provide an option. Sample preparation is minimal, techniques involved are relatively low-cost, and data frameworks are available. This review explores the evidence supporting the applicability of vibrational spectroscopy to generate spectral biomarkers of disease in biofluids. We extend the inter-disciplinary nature of this approach to hypothesise a microfluidic platform that could allow such measurements. With an appropriate lightsource, such engineering could revolutionize screening in the 21(st) century.

    P-glycoprotein is one of the most well-studied drug transporters, significant for its role in cancer multiple drug resistance. However, using P-gp inhibitors with the aim of enhancing the therapeutic efficacy of anti-cancer drugs has led to disappointing outcomes. Furthermore, several lead compounds suggested by in vitro and pre-clinical studies have shown variable pharmacokinetics and therapeutic efficacies when applied in the clinical setting. This review will highlight the need to revisit a sound approach to better design and apply P-gp inhibitors in light of safety and efficacy. Challenges confronting the issue hinge upon myriad studies that do not necessarily represent the heterogeneous target population of this therapeutic approach. The application of P-gp modulators has also been complicated by the promiscuous substrate-binding behaviour of P-gp, as well as toxicities related to its intrinsic presence in healthy tissue. This review capitalizes on information spanning genetics, energetics, and pharmacology, bringing to light some fundamental aspects that ought to be reconsidered in order to improve upon and design the next generation of P-gp inhibitors.

    Problem Current models of health care quality improvement do not explicitly describe the role of health professions education. The authors propose the Exemplary Care and Learning Site (ECLS) model as an approach to achieving continual improvement in care and learning in the clinical setting. Approach From 2008–2012, an iterative, interactive process was used to develop the ECLS model and its core elements—patients and families informing process changes; trainees engaging both in care and the improvement of care; leaders knowing, valuing, and practicing improvement; data transforming into useful information; and health professionals competently engaging both in care improvement and teaching about care improvement. In 2012–2013, a three-part feasibility test of the model, including a site self-assessment, an independent review of each site’s ratings, and implementation case stories, was conducted at six clinical teaching sites (in the United States and Sweden). Outcomes Site leaders reported the ECLS model provided a systematic approach toward improving patient (and population) outcomes, system performance, and professional development. Most sites found it challenging to incorporate the patients and families element. The trainee element was strong at four sites. The leadership and data elements were self-assessed as the most fully developed. The health professionals element exhibited the greatest variability across sites. Next Steps The next test of the model should be prospective, linked to clinical and educa tional outcomes, to evaluate whether it helps care delivery teams, educators, and patients and families take action to achieve better patient (and population) outcomes, system performance, and professional development.

  6. Clinical outcomes of an early intervention program for preschool children with Autism Spectrum Disorder in a community group setting

    PubMed Central

    2013-01-01

    Background Available evidence indicates that early intervention programs, such as the Early Start Denver Model (ESDM), can positively affect key outcomes for children with Autism Spectrum Disorder (ASD). However, programs involving resource intensive one-to-one clinical intervention are not readily available or deliverable in the community, resulting in many children with ASD missing out on evidence-based intervention during their early and most critical preschool years. This study evaluated the effectiveness of the ESDM for preschool-aged children with ASD using a predominantly group-based intervention in a community child care setting. Methods Participants were 26 children (21 male) with ASD with a mean age of 49.6 months. The ESDM, a comprehensive early intervention program that integrates applied behaviour analysis with developmental and relationship-based approaches, was delivered by trained therapists during the child’s attendance at a child care centre for preschool-aged children with ASD. Children received 15–20 hours of group-based, and one hour of one-to-one, ESDM intervention per week. The average intervention period was ten months. Outcome measures were administered pre- and post-intervention, and comprised a developmental assessment - the Mullen Scales of Early Learning (MSEL); and two parent-report questionnaires - the Social Communication Questionnaire (SCQ) and Vineland Adaptive Behaviours Scales–Second Edition (VABS-II). Results Statistically significant post-intervention improvements were found in children’s performance on the visual reception, receptive language and expressive language domains of the MSEL in addition to their overall intellectual functioning, as assessed by standardised developmental quotients. Parents reported significant increases in their child’s receptive communication and motor skills on the VABS-II, and a significant decrease in autism-specific features on the SCQ. These effects were of around medium size, and

  10. Community-acquired diarrhea among children and adults in urban settings in Senegal: clinical, epidemiological and microbiological aspects

    PubMed Central

    2013-01-01

    Background Only limited data are available relating to the etiology of diarrhea in children and adults in Senegal. The aim of this prospective study was to describe the epidemiology and etiology of community-acquired diarrheal infections in children and adults living in urban settings. Methods A prospective study was carried out from March 2009 to December 2010, in the urban region of Dakar, Senegal. Patients with acute diarrhea were enrolled, interviewed to collect their clinical history, and their stools were tested for bacteria, virus and parasites. Results A total of 223 patients (including 112 children younger than five years old) with diarrhea were included. At least one enteropathogen was detected in 81% (180/223) of the patients: 29% (64/223) had bacterial infections (mainly diarrheagenic E. coli and Shigella spp), 21% (39/185) viral infections (mainly rotavirus) and 14% (31/223) parasitic infections. Co-infection was identified in 17.8% (32/180) of the patients. Viral infection was significantly more frequent in children under five years old during the dry season. Bacteria and parasites were equally frequent in all age groups. There was a seasonal variation of bacterial infections during the study period, with a higher proportion of infections being bacterial, and due to Salmonella spp. in particular, during the rainy season. Conclusion Our study suggests that in urban settings in Senegal, rotavirus is the principal cause of pediatric diarrhea during the dry season and that the proportion of bacterial infections seems to be higher during the rainy season. Further work is needed to document the burden of diarrheal diseases in sub-Saharan urban communities and to identify risk factors, including those linked to the rapid and unplanned urbanization in Africa.

    Aspergillus section Nigri includes species of interest for animal and human health, although studies on species distribution are limited to human cases. Data on the antifungal susceptibilities and the molecular mechanism of triazole resistance in strains belonging to this section are scant. Forty-two black Aspergillus strains from human patients (16 isolates), animals (14 isolates), and the environment (12 isolates) were molecularly characterized and their in vitro triazole susceptibilities investigated. Aspergillus tubingensis was isolated from humans, animals, and environmental settings, whereas Aspergillus awamori and Aspergillus niger were isolated exclusively from humans. Phylogenetic analyses of β-tubulin and calmodulin gene sequences were concordant in differentiating A. tubingensis from A. awamori and A. niger. Voriconazole and posaconazole (PSZ) were the most active triazoles. One A. tubingensis strain was resistant to itraconazole and PSZ and one A. niger strain to PSZ. Sequence analysis of the cyp51A gene revealed different sequence types within a species, and A. tubingensis strains were also phylogenetically distinct from A. awamori/A. niger strains according to the strain origin and susceptibility profile. Genetic analysis of the cyp51A sequences suggests that two nonsynonymous mutations resulting in amino acid substitutions in the CYP51A protein (changes of L to R at position 21 [L21R] and of Q to R at position 228 [Q228R]) might be involved in azole resistance. Though azole resistance in black Aspergillus isolates from animals and rural environments does not represent a threat to public health in Southern Italy, the use of triazoles in the clinical setting needs to better monitored. The cyp51A sequence is useful for the molecular identification of black Aspergillus, and point mutations in protein sequences could be responsible for azole resistance phenomena. PMID:27413191

    Objective To compare the effectiveness of biologics, non-biologic systemic therapies, and phototherapy for psoriasis. Design Cross-sectional Setting Ten outpatient dermatology sites across the U.S. Participants 713 plaque psoriasis patients receiving monotherapy: methotrexate, adalimumab, etanercept, ustekinumab, or narrowband ultraviolet B phototherapy. Main Outcome Measures Primary outcome: Clear or almost clear on the Physician Global Assessment. Secondary outcomes: Psoriasis Area and Severity Index, affected body surface area, and Dermatology Life Quality Index. Results The proportion of patients clear or almost clear on the Physician Global Assessment differed among treatments: methotrexate (23.8%), adalimumab (47.7%), etanercept (34.2%), ustekinumab (36.1%), NB-UVB (27.6%) (p < 0.001). In adjusted analyses, patients on adalimumab (relative response rate 2.15, 95% CI 1.60–2.90), etanercept (1.45, 95% CI 1.06–1.97) and ustekinumab (1.57, 95% CI 1.06–2.32) were more likely to have clear or almost clear skin versus patients on methotrexate, while patients receiving phototherapy showed no significant difference (1.35, 95% CI 0.93–1.96) compared to methotrexate. No response difference was observed with respect to quality of life. 36.1% of etanercept and 11.8% of adalimumab patients received double the recommended doses, while 10.6% of phototherapy patients received the recommended treatment frequency. Conclusions The effectiveness of psoriasis therapies in clinical practice may be lower than previously reported in trials. Although relative differences in objective response rates among therapies may exist, absolute differences are small and may not be clinically significant. Dosing of common therapies varied from trial recommendations. These results provide novel benchmarks emphasizing the critical importance of studying effectiveness in real-world practice.

    Background: To interpret blood pressure (BP) data appropriately, healthcare providers need to be knowledgeable of the factors that can potentially impact the accuracy of BP measurement and contribute to variability between measurements. Methods: A systematic review of studies quantifying BP measurement inaccuracy. Medline and CINAHL databases were searched for empirical articles and systematic reviews published up to June 2015. Empirical articles were included if they reported a study that was relevant to the measurement of adult patients’ resting BP at the upper arm in a clinical setting (e.g. ward or office); identified a specific source of inaccuracy; and quantified its effect. Reference lists and reviews were searched for additional articles. Results: A total of 328 empirical studies were included. They investigated 29 potential sources of inaccuracy, categorized as relating to the patient, device, procedure or observer. Significant directional effects were found for 27; however, for some, the effects were inconsistent in direction. Compared with true resting BP, significant effects of individual sources ranged from −23.6 to +33 mmHg SBP and −14 to +23 mmHg DBP. Conclusion: A single BP value outside the expected range should be interpreted with caution and not taken as a definitive indicator of clinical deterioration. Where a measurement is abnormally high or low, further measurements should be taken and averaged. Wherever possible, BP values should be recorded graphically within ranges. This may reduce the impact of sources of inaccuracy and reduce the scope for misinterpretations based on small, likely erroneous or misleading, changes. PMID:27977471

    One of the biggest challenges faced presently by clinicians is the emergence of multi drug--resistant pathogens that can infect humans and animals.To control the infections caused by such pathogens the development of new drugs is required. Bacteria are a rich source of ribosomally-synthesized antimicrobial peptides known as bacteriocins, which are characterized by the presence of a self-defense immunity system. Labionin-containing lantibiotics and sactibiotics are post-translationally modified bacteriocins with peculiar features. Labionin-containing peptides belong tosubclass Iclantibiotics in which the carbacyclic triamino triacid labionin, a structural variant of lanthionine,and a methyl-substitute labionin derivative are found, giving the molecule a labyrinthine structure. Sactibiotics are circular or linear peptides belonging to a distinct bacteriocin class (class V) which is characterized by the presence of cross-linkages formed by the thiol group of cysteine residues and the α-carbon of acceptor amino acids. A few examples of these bacteriocins have been described in the literature to date, although putative gene clusters with the potential to encode such peptides can be found in the genome of many bacterial species. Some peptides already under study exhibit potential biotechnological applications because of their remarkable antibacterial or antiviral activities, as well as their analgesic activity. Therefore, in this review, the main findings concerning these peptides will be addressed and discussed, with anemphasis on their potential use in clinical settings.

    This work presents the first study of x-ray phase contrast imaging based on a simple implementation of the edge illumination method (EIXPCi) in the field of mammography with synchrotron radiation. A simplified EIXPCi set-up was utilized to study a possible application in mammography at clinical doses. Moreover, through a novel algorithm capable of separating and quantifying absorption and phase perturbations of images acquired in EIXPCi modality, it is possible to extract quantitative information on breast images, allowing an accurate tissue identification. The study was carried out at the SYRMEP beamline of Elettra synchrotron radiation facility (Trieste, Italy), where a mastectomy specimen was investigated with the EIXPCi technique. The sample was exposed at three different energies suitable for mammography with synchrotron radiation in order to test the validity of the novel algorithm in extracting values of linear attenuation coefficients integrated over the sample thickness. It is demonstrated that the quantitative data are in good agreement with the theoretical values of linear attenuation coefficients calculated on the hypothesis of the breast with a given composition. The results are promising and encourage the current efforts to apply the method in mammography with synchrotron radiation.

    Background. Timely and adequate treatment is important to limit complications of diabetes affecting pregnancy, but there is a lack of knowledge on how these women are managed in low resource settings. Objective. To identify modalities of gestational diabetes detection and management in low and lower middle income countries. Methods. We conducted a scoping review of published literature and searched the databases PubMed, Web of Science, Embase, and African Index Medicus. We included all articles published until April 24, 2016, containing information on clinical practices of detection and management of gestational diabetes irrespective of publication date or language. Results. We identified 23 articles mainly from Asia and sub-Saharan Africa. The majority of studies were conducted in large tertiary care centers and hospital admission was reported in a third of publications. Ambulatory follow-up was generally done by weekly to fortnightly visits, whereas self-monitoring of blood glucose was not the norm. The cesarean section rate for pregnancies affected by diabetes ranged between 20% and 89%. Referral of newborns to special care units was common. Conclusion. The variety of reported provider practices underlines the importance of promoting latest consensus guidelines on GDM screening and management and the dissemination of information regarding their implementation.

    Summary Objectives Clinical Information Systems (CIS) have ever since the introduction of information technology in healthcare played an important role to support healthcare professionals and the process of treatment. With the rise of the concept of integrated care organizational borders, the sole focus on data aggregation or healthcare professionals as users disappear more and more. The manuscript discusses the concept of CISs and investigates critical success factors for CISs in the context of integrated care and in the course of time. Methods In order to identify critical success factors and barriers for CISs a systematic literature review was conducted based on the results from PubMed and Cochrane, using MaxQDA. Search results were thereby limited to reviews or meta-analysis. Results We have found 1919 references of which 40 met the inclusion criteria. The analysis of the manuscripts resulted in a comprehensive list of success factors and barriers related to CISs in integrated care settings. Most barriers were user-related whereas for the success factors an even distribution of organizational, technical and user-related factors was observed. The vast majority of publications was focused on healthcare professionals. Conclusion It is important to incorporate experiences made/collected over time, as the problems encountered seem to remain almost unvaried. In order to support further systematic investigations on the topic it is necessary to rethink existing concepts and definitions to realign them with the ideas of integrated care. PMID:26293853

    Physical exercise is a cornerstone in the management of many neurodegenerative disorders, such as Parkinson's disease, dementia, and stroke. However, much of its beneficial effects on improving motor functions and cognition as well as decreasing neurodegeneration and neuroinflammation are not yet well understood. The obvious limitations of studying the protective mechanisms behind exercise, for example, brain plasticity and neurodegeneration, could be overcome by generating novel animal models of neurodegenerative disorders. In this narrative review, we discuss the beneficial effects of exercise performed in animal models of neurodegenerative disorders and how the results from animal studies can be used in clinical settings. From preclinical studies, the positive effects of exercise have been related to increased levels of neurotrophic factors, elevated expression of anti-inflammatory cytokines, and reduced levels of pro-inflammatory cytokines and activated microglia. It is clear that parameters influencing the effect of exercise, such as intensity, still remain to be investigated in animal studies in order to find the optimal program that can be translated into exercise interventions for patients with neurodegenerative diseases.

    We aimed to compare the characteristics and outcome of patients treated within the multi-centre German Primary CNS Lymphoma Study Group 1 trial (G-PCNSL-SG-1; TRIAL group) and patients treated outside this clinical trial ("real-life" setting, R-LIFE group). Therefore, we conducted a retrospective single-centre study in order to analyse all patients with newly diagnosed primary CNS lymphoma (PCNSL) treated consecutively in our institution between November 2000 and June 2015. Altogether, 86 patients were analysed (median 68 years). Twenty patients were treated within (TRIAL) and 66 patients outside the clinical trial (R-LIFE), respectively. The majority (n = 75; 87 %) received high-dose methotrexate as the first-line treatment. Thirty-eight of 66 patients (57.6 %) responded to the first-line therapy. The R-LIFE patients were older (median age 70 vs. 62 years; p = 0.005) and had more frequently a worse performance status (ECOG score 2-4: 59.1 vs. 20.0 %; p = 0.004; median Karnofsky index 70 vs. 80 %; p = 0.003) and less frequently a low prognostic score (IELSG score 0-1: 19.7 vs. 45.0 %; p = 0.038), than the TRIAL patients. Median overall survial (OS) was shorter for the R-LIFE patients (9.3 months [95 % CI 1.9-16.7] vs. 33.4 months [95 % CI 17.6-49.2]; p = 0.065). Median progression-free survival (PFS) was significantly inferior for the R-LIFE patients (3.4 months [95 % CI 2.4-4.4] vs. 24.8 months [95 % CI 4.6-45.0]; p = 0.037). Our data indicate that the outcome of PCNSL patients treated outside, but about analogous to the G-PCNSL-SG-1 trial, was poor. This is likely explained by more unfavourable prognostic factors in patients being treated off trial.

    Introduction Cognitive–behavioural therapy (CBT) is effective for treating anxiety disorders and is offered in most mental health services around the world. However, a relatively large number of patients with anxiety disorders do not benefit from CBT, experience relapses or drop out. Reliable predictors of treatment effects are lacking. The aim of this study is to investigate the predictive value of emotion regulation and attentional control for CBT outcome in a routine setting. Methods and analysis In this prospective and practice-based study, 112 patients with anxiety disorders referred for manual-based group CBT at two psychiatric outpatient clinics will be recruited. Emotion regulation, severity of anxiety and attentional control will be assessed with self-report measures and with an experimental computer-based attentional control task at baseline, post-treatment and at a 6-month follow-up. Emotion regulation will be measured with Difficulties in Emotion Regulation Questionnaire, severity of anxiety will be assessed with Beck Anxiety Inventory and attentional control will be measured with the self-report questionnaire, Attention Control Scale, and with an experimental computer-based attentional control task based on theory of visual attention. Data will be analysed using multilevel mixed-effects modelling. Ethics and dissemination The study is approved by the Danish National Ethical Board, the Department of Psychology Ethical Board, University of Copenhagen and by the Danish Data Protection Agency. Study findings will be disseminated through peer-reviewed journal publications and conference presentations. The Danish Committee System on Health Research Ethics has been notified about the project.

    Significant numbers of individuals with severe mental illnesses are difficult to engage in treatment services, presenting challenges for care. To be able to assess the relationship between engagement and discharge outcomes, we modified the "Milestones of Recovery Scale". This scale was modified for content to match the current clinical setting, evaluated for inter-rater reliability after modification in a sample of 233 cases receiving psychiatric rehabilitation, and then was administered to 423 additional psychiatric rehabilitation clients over a 24-month study period. In an effort to determine whether provision of financial incentives lead to sustained increases in client engagement, a cut off for client eligibility for financial incentives was evaluated on the basis of the reliability study and the course of engagement was related to receipt of this incentive and successful completion of treatment in a new sample of 423 patients. Of this sample, 78 % received an initial financial incentive during treatment (were initially engaged), and 93.3 % of that subgroup sustained this level of engagement it over their entire course of treatment. Of the 22 % of cases not receiving an initial incentive, only 5.4 % improved in their engagement to levels required for the incentive. Longitudinal analysis demonstrated that individuals who maintained or increased their level of engagement over time were more likely to complete treatment in accordance with planned treatment goals. The initial engagement and the course of engagement in treatment predicted successful completion, but incentives did not lead to increased engagement in initially poorly engaged patients. These data are interpreted in terms of the likely success of extrinsic rewards to increase engagement in mental health services.

    One component of the recent obesity epidemic is the sedentary behaviour of children and adolescents e.g., use of video games consoles. The new generation of video games requires body movements and might thus increase activity. The aim of this study was to evaluate whether such games could have an effect on physical activity in obese adolescents in a clinical setting. Between March and May 2007 activity-promoting video games ("apvg") were offered to all 84 inpatients (aged 13-28 years) registered in a long-term rehabilitation programme on a voluntary base. Reasons for (non-)attendance were assessed. Frequency and duration of use of the activity-promoting video game sessions were documented. Furthermore, heart rate and activity counts during use of "apvg", endurance training, and strength training were measured. Of 84 inpatients, 51 used the "apvg" at least once (69%) over the study period. The median weekly use of the intervention was 27 min during the first week (range 0-182 min), declining to zero (range 0-74 min) in week four. Mean heart rate during the sessions (mean 115 bpm; 95% confidence interval 108-122 bpm) was similar to the heart rate during strength training (106 bpm; 101-112 bpm). The results indicate that the video games could have an impact on the activity of obese adolescents and young adults. However, as the interest in the devices seems to be too low the suitability of them for weight reduction programmes in young people cannot be ensured.

    Ibandronate, a nitrogen-containing bisphosphonate, is a bone resorption inhibitor widely used to prevent and treat osteoporosis. To optimize the design for a long-term clinical study of ibandronate, modeling and simulation (M&S) was performed based on the result of population pharmacodynamic analysis using the data of a short-term clinical study. A population pharmacodynamic model was constructed by the urinary C-terminal telopeptide of type I collagen (uCTx) and the lumbar spine bone mineral density (BMD) data obtained in clinical studies, including a phase II study of Japanese osteoporosis patients treated with ibandronate for 6 months. Changes in BMD over a period of 3 years were simulated from the population pharmacodynamic parameters of the patients in this phase II study. The relationship between uCTx and BMD was well described by this modeling. The functions of disease progression and supplemental treatment were incorporated into the model to simulate a long-term clinical study with high accuracy. A long-term clinical study with a 3-year treatment was conducted after this M&S. The percentage change from baseline in observed BMD values were found to be similar to the prospectively simulated values. This study showed that M&S could be a useful and powerful tool for designing and conducting long-term clinical studies when carried out in the following sequence: (1) conduct a short-term clinical study; (2) perform M&S; and (3) conduct the long-term clinical study. Application of this procedure to various other treatment agents will establish the usefulness of M&S for long-term clinical studies and bring further efficiencies to drug development.

    Few resources are available to quantify clinical trial-associated workload, needed to guide staffing and budgetary planning. The aim of the study is to describe a tool to measure clinical trials nurses' workload expressed in time spent to complete core activities. Clinical trials nurses drew up a list of nursing core activities, integrating results from literature searches with personal experience. The final 30 core activities were timed for each research nurse by an outside observer during daily practice in May and June 2014. Average times spent by nurses for each activity were calculated. The "Nursing Time Required by Clinical Trial-Assessment Tool" was created as an electronic sheet that combines the average times per specified activities and mathematic functions to return the total estimated time required by a research nurse for each specific trial. The tool was tested retrospectively on 141 clinical trials. The increasing complexity of clinical research requires structured approaches to determine workforce requirements. This study provides a tool to describe the activities of a clinical trials nurse and to estimate the associated time required to deliver individual trials. The application of the proposed tool in clinical research practice could provide a consistent structure for clinical trials nursing workload estimation internationally.

    Objective: To compare the effectiveness of various caries removal techniques in mandibular primary molars using Smart Burs, atraumatic restorative technique (ART) (mechanical caries removal) and Carie-care (chemomechanical caries removal [CMCR]) among primary school children in clinical and community-based settings. Materials and Methods: A total of 80 carious primary mandibular molars were selected for the study from the dental clinic and community. They were equally assigned to four groups according to caries removal technique and also by the operating site. In Group 1, caries was removed using Carie-care in the dental clinic and in Group 2, with Smart Burs in the dental clinic. In Group 3, caries was removed using Carie-care in the field and in Group 4, with the ART in the field. The time taken for caries removal, the efficacy of caries removal and patient acceptance were evaluated with different caries removal techniques. Statistical Analysis: The obtained data were subjected to statistical analysis by ANOVA test. Results: In clinical settings, Carie-care was time-consuming but was more efficient with increased acceptance than Smart Burs and the result was found to be significant statistically (P < 0.05). In community-based settings, Carie-care was more efficient, less time consuming, and showed an increased acceptance when compared to atraumatic restorative treatment and the result was found to be significant statistically (P < 0.05). Conclusions: The CMCR technique was superior to the mechanical caries removal technique in primary teeth among school children in terms of time, efficacy, and acceptance in both clinical- and community-based settings.

    2010-01-01

    Palliative care in India has made enormous advances in providing better care for patients and families living with progressive disease, and many clinical services are well placed to begin quality improvement initiatives, including clinical audit. Clinical audit is recognized globally to be essential in all healthcare, as a way of monitoring and improving quality of care. However, it is not common in developing country settings, including India. Clinical audit is a cyclical activity involving: identification of areas of care in need of improvement, through data collection and analysis utilizing an appropriate questionnaire; setting measurable quality of care targets in specific areas; designing and implementing service improvement strategies; and then re-evaluating quality of care to assess progress towards meeting the targets. Outcome measurement is an important component of clinical audit that has additional advantages; for example, establishing an evidence base for the effectiveness of services. In resource limited contexts, outcome measurement in clinical audit is particularly important as it enables service development to be evidence-based and ensures resources are allocated effectively. Key success factors in conducting clinical audit are identified (shared ownership, training, managerial support, inclusion of all members of staff and a positive approach). The choice of outcome measurement tool is discussed, including the need for a culturally appropriate and validated measure which is brief and simple enough to incorporate into clinical practice and reflects the holistic nature of palliative care. Support for clinical audit is needed at a national level, and development and validation of an outcome measurement tool in the Indian context is a crucial next step. PMID:20859465

    2008-10-01

    Evidence-based medicine (EBM) is an indispensable tool in clinical practice. Teaching and training of EBM to trainee clinicians is patchy and fragmented at its best. Clinically integrated teaching of EBM is more likely to bring about changes in skills, attitudes and behaviour. Provision of evidence-based health care is the most ethical way to practice, as it integrates up-to-date, patient-oriented research into the clinical decision making process, thus improving patients' outcomes. In this article, we aim to dispel the myth that EBM is an academic and statistical exercise removed from practice by providing practical tips for teaching the minimum skills required to ask questions and critically identify and appraise the evidence and presenting an approach to teaching EBM within the existing clinical and educational training infrastructure.

    2014-12-01

    Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS)-based species identification has become a reliable and fast tool for use in clinical diagnostics, including in mycology. To identify yeasts in the MALDI Biotyper system, a multistep extraction protocol, which is also used to generate the reference spectra, is recommended. Sample preparation by on-target lysis (OTL) requires significantly less hands-on time and is therefore highly desirable, but it results in too-low MALDI Biotyper log score values to allow automated species identification. To overcome this problem, we developed a procedure for generating and validating an OTL spectrum data set for the most relevant and frequently occurring yeast species in clinical specimens. The performance was evaluated against a set of OTL spectra derived during clinical routine procedures and from a set of closely related yeasts. In the diagnostic setting, the OTL procedure significantly decreased the workload but allowed species identification with high specificity and sensitivity. False identifications were not observed. The use of in-house-generated OTL reference spectra can highly accelerate MALDI-TOF MS-based yeast species identification using the MALDI Biotyper.

    Cognitive behavioral therapy-based guided self-help (CBT-GSH) via the Internet has been shown to be effective in the treatment of bulimia nervosa (BN) and similar eating disorders (EDs), but it is rarely offered, and little is known about the effects, in clinical settings. The present study investigated the effects of a bibliotherapy-based CBT-GSH with Internet support in a clinical setting. Participants were 48 adult outpatients who were recruited without randomization from a specialized ED clinic, diagnosed with BN or similar eating disorder. Forty-eight patients in an intensive day patient program (DPP) were used as comparison group. The Eating Disorder Examination Questionnaire (EDE-Q) and the Eating Disorder Inventory 2 measured pre- and post treatment symptoms. Results showed that both groups attained significant improvements in core- as well as related ED symptoms in both instruments. As expected, treatment effects were larger in the more intensive DPP. Nonetheless, bibliotherapy CBT-GSH appears to be a cost-effective treatment that represents a new way to provide more CBT in clinical settings.

    The most actual goals of geoethics have been formulated as results of the International Conference on Geoethics (October 2013) held at the geoethics birth-place Pribram (Czech Republic): In the sphere of education and public enlightenment an appropriate needed minimum know how of Earth sciences should be intensively promoted together with cultivating ethical way of thinking and acting for the sustainable well-being of the society. The actual activities of the Intergovernmental Panel of Climate Changes are not sustainable with the existing knowledge of the Earth sciences (as presented in the results of the 33rd and 34th International Geological Congresses). This knowledge should be incorporated into any further work of the IPCC. In the sphere of legislation in a large international co-operation following steps are needed: - to re-formulate the term of a "false alarm" and its legal consequences, - to demand very consequently the needed evaluation of existing risks, - to solve problems of rights of individuals and minorities in cases of the optimum use of mineral resources and of the optimum protection of the local population against emergency dangers and disasters; common good (well-being) must be considered as the priority when solving ethical dilemmas. The precaution principle should be applied in any decision making process. Earth scientists presenting their expert opinions are not exempted from civil, administrative or even criminal liabilities. Details must be established by national law and jurisprudence. The well known case of the L'Aquila earthquake (2009) should serve as a serious warning because of the proven misuse of geoethics for protecting top Italian seismologists responsible and sentenced for their inadequate superficial behaviour causing lot of human victims. Another recent scandal with the Himalayan fossil fraud will be also documented. A support is needed for any effort to analyze and to disclose the problems of the deformation of the contemporary

  16. Ethical challenges in integrating patient-care with clinical research in a resource-limited setting: perspectives from Papua New Guinea

    PubMed Central

    2013-01-01

    Background In resource-limited settings where healthcare services are limited and poverty is common, it is difficult to ethically conduct clinical research without providing patient-care. Therefore, integration of patient-care with clinical research appears as an attractive way of conducting research while providing patient-care. In this article, we discuss the ethical implications of such approach with perspectives from Papua New Guinea. Discussion Considering the difficulties of providing basic healthcare services in developing countries, it may be argued that integration of clinical research with patient-care is an effective, rational and ethical way of conducting research. However, blending patient-care with clinical research may increase the risk of subordinating patient-care in favour of scientific gains; therapeutic misconception and inappropriate inducement; and the risk of causing health system failures due to limited capacity in developing countries to sustain the level of healthcare services sponsored by the research. Nevertheless, these ethical and administrative implications can be minimised if patient-care takes precedence over research; the input of local ethics committees and institutions are considered; and funding agencies acknowledge their ethical obligation when sponsoring research in resource-limited settings. Summary Although integration of patient-care with clinical research in developing countries appears as an attractive way of conducting research when resources are limited, careful planning and consideration on the ethical implications of such approach must be considered.

    Understanding human filovirus hemorrhagic fever (FHF) clinical manifestations and evaluating treatment strategies require the collection of clinical data in outbreak settings, where clinical documentation has been limited. Currently, no consensus among filovirus outbreak-response organisations guides best practice for clinical documentation and data transfer. Semi-structured interviews were conducted with health care workers (HCWs) involved in FHF outbreaks in sub-Saharan Africa, and with HCWs experienced in documenting and transferring data from high-risk areas (isolation wards or biosafety level 4 laboratories). Methods for data documentation and transfer were identified, described in detail and categorised by requirement for electricity and ranked by interviewee preference. Some methods involve removing paperwork and other objects from the filovirus disease ward without disinfection. We believe that if done properly, these methods are reasonably safe for certain settings. However, alternative methods avoiding the removal of objects, or involving the removal of paperwork or objects after non-damaging disinfection, are available. These methods are not only safer, they are also perceived as safer and likely more acceptable to health workers and members of the community. The use of standardised clinical forms is overdue. Experiments with by sunlight disinfection should continue, and non-damaging disinfection of impregnated paper, suitable tablet computers and underwater cameras should be evaluated under field conditions.

    The aim of this study was to provide a descriptive analysis of a new clinical program integrating psychology services within a pediatric outpatient cardiology clinic. Patients with congenital heart disease (CHD) (n = 79) were referred for psychological services by their pediatric cardiologist. Parents completed the child behavior checklist, and the pediatric quality of life inventory generic core scales (PedsQL parent report). Teachers completed the teacher report form. Reasons for referral included: emotional problems (29%); attention problems (25%); learning problems (22%); behavior problems (16%); and developmental delay (8%). Parents and teachers reported higher rates of behavior problems and lower quality of life scores than the general population. Psychological evaluation suggested that incorporating a psychologist within a pediatric cardiology clinic may be beneficial for children with CHD in order to optimize their psychosocial functioning. Practice implications for implementing psychology services within a pediatric outpatient cardiology program are discussed.

    Background Despite an extensive evaluation program, patients may remain diagnostically unresolved with regard to the etiology of their cognitive dysfunction. Cerebrospinal fluid neuroinflammation and Alzheimer disease (AD) biomarkers may act as indicators of neurodegenerative disorders in diagnostically unresolved patients. Methods Data on 348 patients were retrospectively evaluated. All participants had a standardized diagnostic workup and follow-up in a memory clinic. Results Aβ42 levels and Aβ42/p-tau ratios were reduced and levels of t-tau and p-tau as well as the t-tau × p-tau/Aβ42 ratio were elevated in diagnostically unresolved patients who clinically progressed, compared to a stable group. No differences in neuroinflammatory parameters were found. Conclusion AD biomarkers - in particular the Aβ42/p-tau ratio, but not neuroinflammatory parameters - predicted clinical progression, regardless of etiology. PMID:27843444

    Diagnostic accuracy in FDG-PET imaging highly depends on the operating procedures. In this clinical study on dementia, we compared the diagnostic accuracy at a single-subject level of a) Clinical Scenarios, b) Standard FDG Images and c) Statistical Parametrical (SPM) Maps generated via a new optimized SPM procedure. We evaluated the added value of FDG-PET, either Standard FDG Images or SPM Maps, to Clinical Scenarios. In 88 patients with neurodegenerative diseases (Alzheimer's Disease—AD, Frontotemporal Lobar Degeneration—FTLD, Dementia with Lewy bodies—DLB and Mild Cognitive Impairment—MCI), 9 neuroimaging experts made a forced diagnostic decision on the basis of the evaluation of the three types of information. There was also the possibility of a decision of normality on the FDG-PET images. The clinical diagnosis confirmed at a long-term follow-up was used as the gold standard. SPM Maps showed higher sensitivity and specificity (96% and 84%), and better diagnostic positive (6.8) and negative (0.05) likelihood ratios compared to Clinical Scenarios and Standard FDG Images. SPM Maps increased diagnostic accuracy for differential diagnosis (AD vs. FTD; beta 1.414, p = 0.019). The AUC of the ROC curve was 0.67 for SPM Maps, 0.57 for Clinical Scenarios and 0.50 for Standard FDG Images. In the MCI group, SPM Maps showed the highest predictive prognostic value (mean LOC = 2.46), by identifying either normal brain metabolism (exclusionary role) or hypometabolic patterns typical of different neurodegenerative conditions.

    Wilms tumour is a relatively common and curable paediatric tumour. Known challenges to cure in low income countries are late presentation with advanced disease, malnutrition, failure to complete treatment and limited facilities. In this article, management recommendations are given for a low income setting where only the minimal requirements for treatment with curative intent are available (setting 1). These include general management, supportive care, social support and registration of patients. Recommendations specific for Wilms tumour care include diagnostic procedures with emphasis on the role of ultrasonography, preoperative chemotherapy with a reduced dosage for malnourished children and postoperative chemotherapy based on surgical staging.

    Although the importance of empathy, rapport, and anxiety/pain awareness in dentist-patient relations has been well documented, these factors continue to be an issue with patients in many dental school clinics. The aim of this study was to develop an in-depth understanding of how patients at an urban, university-affiliated medical center and its dental school's clinic experienced oral health care and to generate ideas for improving the dental school's clinical curriculum and management of the clinic. Although patient satisfaction surveys are common, in-depth patient narratives are an underutilized resource for improving dental education. In-depth qualitative interviews were conducted with 20 uninsured or underinsured dental patients at these sites, and the results were analyzed using content analysis. Major phenomena that participants discussed were the importance of empathy and good rapport with their oral health providers and provider awareness of dental pain and anxiety. Many patients also discussed feeling dehumanized during dental visits. Based on their positive and negative experiences, the participants made suggestions for how oral health professionals can successfully engage patients in treatment.

    Aim: The aim of this study is to compare the different caries diagnostic thresholds under epidemiological and clinical settings among 7-15 year old school children. Materials and Methods: A cross-sectional study was undertaken among 7-15 years old school children of Bangalore city. Total 738 children were enrolled in the study. General information was collected regarding oral hygiene practice and personal habits of the schoolchildren. Subsequently, examination was done under both the settings to record Decayed, missing and filled surfaces index for permanent teeth (DMFS) and Decayed, missing and filled surfaces index for deciduous teeth (dmfs) using the World Health Organization (WHO) and WHO + IL criteria. Results: The present study showed that both the settings (clinical and epidemiological) and diagnostic thresholds (WHO and WHO + IL), could influence the detection of carious lesions. Mean Ds under WHO + Initial lesions (IL) criteria (3.92 + 3.49) was nearly double of WHO criteria (1.88 + 2.73,) and the influence observed was more in 14 years of age, where mean Ds under WHO + IL criteria (5.43 + 2.5) which was more than double of WHO criteria (2.02 + 1.9). Conclusion: The choice of a diagnostic threshold (WHO and WHO + IL) and the conditions of examination (epidemiological and clinical) are important for the detection of caries. PMID:24778986

    The present article maps out understandings about embodied distress among gender-nonconforming youth. Feminist bioethics and queer-inflected clinical perspectives are used to inform thinking about ethical, nonpathologizing health care in the case of gender-related distress. Specific attention is directed at self-harming among gender variant and trans youth. This is contextualized in relation to the role that self-harm plays for some LGBT youth, where it may be seen as a rite of passage or as reasonable and inevitable way of coping. The particular complexities of self-harm among trans youth seeking clinical intervention are examined. Queer bioethics is proposed as potentially facilitating productive uncertainty with regard to the diverse imagined futures of gender variant and trans youth.

    Advances in optical character recognition (OCR) software and computer hardware have stimulated a reevaluation of the technology and its ability to capture structured clinical data from preexisting paper forms. In our pilot evaluation, we measured the accuracy and feasibility of capturing vitals data from a pediatric encounter form that has been in use for over twenty years. We found that the software had a digit recognition rate of 92.4% (95% confidence interval: 91.6 to 93.2) overall. More importantly, this system was approximately three times as fast as our existing method of data entry. These preliminary results suggest that with further refinements in the approach and additional development, we may be able to incorporate OCR as another method for capturing structured clinical data.

    This study examines developmental, clinical, gender, and ethnic group differences in preference in residentially placed children and adolescents. In addition, this study considers whether residentially placed youth prefer stimuli currently being used as rewards as part of a campuswide token economy system and whether youth would identify preferred stimuli that are not currently offered. The article discusses a survey devised specifically for the purpose of this study. Stimuli currently offered as rewards are listed and rated on a 5-point Likert-type scale. Results indicate that the majority of stimuli available within the token economy system were rated as preferred. Also, significant developmental, clinical, gender, and ethnic group differences are found, indicating the benefit of considering group-level characteristics when designing and implementing a groupwide token economy system. The implications of the results and directions for future research are discussed.

    We report the clinical features of 149 cases with aerial devices burns in a public fireworks display. The characteristic features included sudden onset, masses of terrified burn victims, small and deep wounds, mild disease conditions, and favorable prognosis. Unlike in home or illegal fireworks displays, the body areas most often involved were the extremity, chest, abdomen, and back, and most of the victims were adults in these public fireworks displays.

    The purpose of this study was to identify predictors and/or factors associated with medically compromised patients seeking dental care in the oncology dental support clinic (ODSC) at the University of Missouri-Kansas City (UMKC) School of Dentistry. An 18-item survey was mailed to 2,541 patients who were new patients to the clinic from 2006 to 2011. The response rate was approximately 18% (n = 450). Analyses included descriptive statistics of percentages/frequencies as well as predictors based on correlations. Fifty percent of participants, 100 females and 119 males, identified their primary medical diagnosis as cancer. Total household income (p < .001) and the importance of receiving dental care (p < .001) were significant factors in relation to self-rated dental health. Perceived overall health (p < .001) also had a significant association with cancer status and the need for organ transplants. This study provided the ODSC at UMKC and other specialty clinics with vital information that can contribute to future planning efforts.

    The approach to the acquired immune deficiency syndrome (AIDS) taken by public health departments and clinicians varies. Public health programs often neglect the human side of AIDS while clinicians often overlook public health issues. Current research on AIDS has failed to address many fundamental questions including: the biology of the human immunodeficiency virus (HIV) in semen; whether present antiretroviral therapy has any effect on sexual infectivity; and whether adequate counseling was given to persons in HIV discordant partner studies. These unanswered basic questions highlight how research efforts framed from clinical, basic science, or public health viewpoints may have too narrow a focus. Three suggestions are made: 1) additional studies about the biology of HIV in the genital tract need to be conducted; 2) clinical trials studying drug therapy of HIV infection need to assess effect on HIV in the genital tract; 3) clinicians involved in studies and care of HIV infection need to implement educational strategies minimizing transmission of HIV from their patients. More interaction between public health and clinical approaches toward AIDS is needed. PMID:3407822

    Objective: Nasal bubble continuous positive airway pressure (bCPAP) is preferred in developing economies for easy applicability and low cost. Because its use in older children is unexplored, we sought to evaluate its utility in hypoxemic clinical pneumonia. Methods: Of 330 children (1 month–12 years) with clinical pneumonia enrolled prospectively over 1 year, those with increased work of breathing and/or SpO2 <92% received bCPAP delivered via an underwater ‘T' tube through nasal prongs. Proportion requiring intubation despite bCPAP constituted primary outcome. Incidence of complications, duration of bCPAP and emergency stay were secondary outcomes. Results: Oxygen was initiated by nasal prongs (NPO2) in 204 (61.8%), and by bCPAP in 110 (33.3%). Sixteen (4.8%) were intubated at the outset. Fifty-three (25.9%) on NPO2 were shifted to bCPAP for worsening distress and hypoxemia. Only three (1.8%) from bCPAP group required intubation, of which one died. Failure rate and complications were negligent. The median emergency stay was 4 days. Conclusions: Nasal bCPAP was safe and effective in children with hypoxemic clinical pneumonia. PMID:26428195

    Prognostic parameters and indicators of deterioration of prolastin substituted alpha 1 antitrypsin deficient COPD (AAT) are poorly defined. In particular, there is a lack of information how patients with AAT report exacerbations or how intravenous therapy with prolastin is tolerated and leads to a stabilization of the clinical course of the disease. In a prospective study seven patients were followed over 36 months who received i. v. prolastin at home. Both clinical parameters such as exacerbations and spirometric lung function tests were used to monitor the clinical course of the disease. During the time period given 2.1 exacerbations/year were documented, the average lung function loss over the period of 36 month was mean FEV1 1.02 ± 0.61 l/s to 0.94 ± 0.63 l/s and mean vital capacity 2.95 ± 0.82 l to 2.87 ± 0.81 l. Complications related to home based infusion therapy did not occur. No non elective hospitalisations were reported. Taken together, this prospective feasibility trial could show that home based i. v. therapy in patients with AAT is safe and leads to less exacerbations and loss of lung function as compared to the historical cohort.

    The present and accepted standard for determining the status of tissue relies on visual inspection of the tissue. Based on the surface appearance of the tissue, medical personnel will make an assessment of the tissue and proceed to a course of action or treatment. Visual inspection of tissue is central to many areas of clinical medicine, and remains a cornerstone of dermatology, reconstructive plastic surgery, and in the management of chronic wounds, and burn injuries. Near infrared spectroscopic imaging holds the promise of being able to monitor the dynamics of tissue physiology in real-time and detect pathology in living tissue. The continuous measurement of metabolic, physiological, or structural changes in tissue is of primary concern in many clinical and biomedical domains. A near infrared hyperspectral imaging system was constructed for the assessment of burn injuries and skin flaps or skin grafts. This device merged basic science with engineering and integrated manufacturing to develop a device suitable to detect ischemic tissue. This device has the potential of providing measures of tissue physiology, oxygen delivery and tissue hydration during patient screening, in the operating room or during therapy and post-operative/treatment monitoring. Results from a pre-clinical burn injury study will be presented.

    Since the diagnostic characteristics of the Check-KPC ESBL microarray as a confirmation test on isolates obtained in a routine clinical setting have not been determined, we evaluated the microarray in a random selection of 346 clinical isolates with a positive ESBL screen test (MIC >1 mg/L for cefotaxime or ceftazidime or an ESBL alarm from the Phoenix or Vitek-2 expert system) collected from 31 clinical microbiology laboratories in the Netherlands in 2009. Using sequencing as the reference method the sensitivity of the microarray was 97% (237/245), the specificity 98% (97/99), the positive predictive value 99% (237/239) and the negative predictive value 92% (97/105).

    With the worldwide strategic shift of health care delivery from secondary to primary care settings, more newly qualified nurses are working in primary care, making exposure to the variety of roles available to nurses essential for future workforce development. The aim of this small research project was to explore whether English universities' programmes are providing clinical practice placement experiences which reflect the breadth and complexity of nursing roles available in primary care. A survey of academic staff highlighted that universities designed curricula based on local placement and mentor availability and while a variety of primary care teams are being used, district nursing teams continue to be used the most, particularly for substantive placements. The need for specified staff to work across university and placement settings was deemed essential for identifying and supporting community based clinical placements. Recommendations from the project include: an increasingly collaborative approach amongst clinical, academic and managerial staff to create a learning culture for all health professional students' practice experience; robust strategic systems to ensure clinical placements are offered by services on the periphery of a national health service; and focussing of resources on students with a desire to pursue a primary care career.

    The U.S. Department of Energy plans to vitrify approximately 60,000 metric tons of high-level waste (HLW) sludge from underground storage tanks at the Hanford Nuclear Reservation. To reduce the volume of HLW requiring treatment, a goal has been set to remove a significant quantity of the aluminum, which comprises nearly 70 percent of the sludge. Aluminum is found in the form of gibbsite, sodium aluminate and boehmite. Gibbsite and sodium aluminate can be easily dissolved by washing the waste stream with caustic. Boehmite, which comprises nearly half of the total aluminum, is more resistant to caustic dissolution and requires higher treatment temperatures and hydroxide concentrations. Samples were taken from four Hanford tanks and homogenized in order to give a sample that is representative of REDOX (Reduction Oxidation process for Pu recovery) sludge solids. Bench scale testing was performed on the homogenized waste to study the dissolution of boehmite. Dissolution was studied at three different hydroxide concentrations, with each concentration being run at three different temperatures. Samples were taken periodically over the 170 hour runs in order to determine leaching kinetics. Results of the dissolution studies and implications for the proposed processing of these wastes will be discussed.

    Patients with castration-resistant prostate cancer (CRPC) often are treated with drugs that target the androgen receptor (AR) ligand-binding domain. Constitutively active AR splice variant 7 (AR-V7) lacks the ligand-binding domain and, if detected in circulating tumor cells, may be associated with resistance to these agents. We validated an AR-V7 assay in a Clinical Laboratory Improvement Amendments (CLIA)-certified laboratory. Circulating tumor cells were isolated, and mRNA was reverse-transcribed into cDNA. Real-time quantitative PCR amplification of reference transcripts (beta-actin and glyceraldehyde-3-phosphate dehydrogenase), prostate-specific transcripts (prostate-specific membrane antigen, prostate-specific antigen, and AR-full length), and AR-V7 was performed. Specimens for validation included an AR-V7 expressing prostate cancer (LNCaP95), 38 peripheral blood controls, and 21 blood samples from CRPC patients. The assay detected as few as five LNCaP95 cells spiked into peripheral blood, showing high analytical sensitivity. Multiple inter-run and intrarun replicates of LNCaP95 cell line experiments yielded similar cycle threshold values for all genes, showing high analytical precision (AR-V7 cycle threshold CV of 0.67%). All 38 healthy control samples were negative for AR-V7, showing high diagnostic specificity (100%). The diagnostic accuracy was confirmed by concurrent testing of 21 CRPC samples in the research laboratory and the clinical diagnostic laboratory: concordance in AR-V7 status was achieved in all cases (positive in 4, negative in 17) (100% accuracy). This first validated clinical assay detects the AR-V7 with high analytical sensitivity, precision, specificity, and accuracy.

    Current treatment of metastatic bone prostate cancer with Docetaxel chemotherapy per CHAARTED trial is standard of care. Timing of CT and bone scintigraphy for evaluation of successful treatment of lytic lesions is not available in the literature. We present a case of a 70 year old male with PSA of 586 and wide spread metastatic bone lytic lesions, who underwent androgen deprivation therapy and six cycles of Docetaxel chemotherapy. The patient had clinically successful treatment. Contrast enhanced CT scan demonstrated sclerotic bone lesions with PSA 2.5 at this point in treatment; however, 99mTc-MDP bone scintigraphy remained positive for metastatic lesions. PMID:27169018

    2008-09-01

    The culmination of methodology explored and developed in the preceding three papers is described in terms of the FANO program (also known as CliniMiner) and specifically in terms of the contemporary command set for data mining. This provides a more detailed account of how strategies were implemented in applications described elsewhere, in the previous papers in the series and in a paper on the analysis of 667 000 patient records. Although it is not customary to think of a command set as the output of research, it represents the elements and strategies for data mining biomedical and clinical data with many parameters, that is, in a high dimensional space that requires skilful navigation. The intent is not to promote FANO per se, but to report its science and methodologies. Typical example rules from traditional data mining are that A and B and C associate, or IF A & B THEN C. We need much higher complexity rules for clinical data especially with inclusion of proteomics and genomics. FANO's specific goal is to be able routinely to extract from clinical record repositories and other data not only the complex rules required for biomedical research and the clinical practice of evidence based medicine, but to quantify their uncertainty, that is, their essentially probabilistic nature. The underlying information and number theoretic basis previously described is less of an issue here, being "under the hood", although the fundamental role and use of the Incomplete (generalized) Riemann Zeta Function as a general surprise measure is highlighted, along with its covariance or multivariance analogue, as it appears to be a unique and powerful feature. Another characteristic described is the very general tactic of the metadata operator ':='. It allows decomposition of diverse data types such as trees, spreadsheets, biosequences, sets of objects, amorphous data collections with repeating items, XML structures, and so forth into universally atomic data items with or without

    Recent research findings suggest that many children with Autism Spectrum Disorders (ASD) demonstrate delayed and atypical motor achievements. It has now become clear that a more holistic, integrative and multi-disciplinary intervention is required to effectively address the motor-related impairments of this population. It is also crucial to ensure that this group of clients has access to early physical therapy (PT) interventions. Despite accumulating research on physical interventions, little is known about intervention model for implementation at a national level. This report introduces a model that uniquely illustrates implementation of PT services for a large number of children with ASD. The model has been operating for the past 2 years in one country (Israel), and includes an optional implementation model of PT practice settings for young children diagnosed with ASD. The Israeli setting offers a unique opportunity for implementing PT services for a multitude of children with ASD on a regular basis as an accepted/needed service. The initial outcomes of the present implementation suggest that an intensive PT intervention program might enhance therapeutic outcomes for this population, and contribute to our knowledge on the potential of PT for individuals with ASD.

    2016-01-01

    Thyroid hormone abnormalities are common in critically ill patients. For over three decades, a mild form of these abnormalities has been described in patients with several diseases under outpatient care. These alterations in thyroid hormone economy are a part of the nonthyroidal illness and keep an important relationship with prognosis in most cases. The main feature of this syndrome is a fall in free triiodothyronine (T3) levels with normal thyrotropin (TSH). Free thyroxin (T4) and reverse T3 levels vary according to the underlying disease. The importance of recognizing this condition in such patients is evident to physicians practicing in a variety of specialties, especially general medicine, to avoid misdiagnosing the much more common primary thyroid dysfunctions and indicating treatments that are often not beneficial. This review focuses on the most common chronic diseases already known to present with alterations in serum thyroid hormone levels. A short review of the common pathophysiology of the nonthyroidal illness is followed by the clinical and laboratorial presentation in each condition. Finally, a clinical case vignette and a brief summary on the evidence about treatment of the nonthyroidal illness and on the future research topics to be addressed are presented. PMID:27803712

    Assessment of body composition, both at single time points and longitudinally, is particularly important in clinical nutrition practice. It provides a means for the clinician to characterize nutrition status at a single time point, aiding in the identification and diagnosis of malnutrition, and to monitor changes over time by providing real-time information on the adequacy of nutrition interventions. Objective body composition measurement tools are available clinically but are often underused in nutrition care, particularly in the United States. This is, in part, due to a number of factors concerning their use in a clinical context: cost and accessibility of equipment, as well as interpretability of the results. This article focuses on the factors influencing interpretation of results in a clinical setting. Body composition assessment, regardless of the method, is inherently limited by its indirect nature. Therefore, an understanding of the strengths and limitations of any method is essential for meaningful interpretation of its results. This review provides an overview of body composition technologies available clinically (computed tomography, dual-energy x-ray absorptiometry, bioimpedance, ultrasound) and discusses the strengths and limitations of each device.

    Dengue virus is endemic globally, throughout tropical and sub-tropical regions. While the number of epidemics due to the four DENV serotypes is pronounced in East Africa, the total number of cases reported in Africa (16 million infections) remained at low levels compared to Asia (70 million infections). The French Armed forces Health Service provides epidemiological surveillance support in the Republic of Djibouti through the Bouffard Military hospital. Between 2011 and 2014, clinical and biological data of suspected dengue syndromes were collected at the Bouffard Military hospital and analyzed to improve Dengue clinical diagnosis and evaluate its circulation in East Africa. Examining samples from patients that presented one or more Dengue-like symptoms the study evidenced 128 Dengue cases among 354 suspected cases (36.2% of the non-malarial Dengue-like syndromes). It also demonstrated the circulation of serotypes 1 and 2 and reports the first epidemic of serotype 3 infections in Djibouti which was found in all of the hospitalized patients in this study. Based on these results we have determined that screening for Malaria and the presence of the arthralgia, gastro-intestinal symptoms and lymphopenia < 1,000cell/ mm3 allows for negative predictive value and specificity of diagnosis in isolated areas superior to 80% up to day 6. This study also provides evidence for an epidemic of Dengue virus serotype 3 previously not detected in Djibouti.

    Although breast cancer is one of the leading causes of death in women worldwide, there is an overall improvement in the survival of this patient population. This is likely due to a combination of early detection through screening and awareness, improved targeted biological therapy, and an overall improvement in disease management. Despite the beneficial effects of the 2 anti-cancer drugs doxorubicin (DOX) and trastuzumab (TRZ) in women with breast cancer, development of cardiotoxicity is a major concern. The occurrence of left ventricular systolic dysfunction is unacceptably high in nearly 1 in 4 women treated with DOX+TRZ in the breast cancer setting. In this review, we explore the use of non-invasive cardiac imaging for the early detection of chemotherapy-mediated cardiotoxicity in women with breast cancer, in the hope of preventing end-stage heart disease in this cancer population.

    Chronic pain affects millions of Americans and can be addressed through multiple modalities, interventions, and strategies. Yoga and self-management have been proven effective in treating chronic pain, but little research has been conducted on the feasibility and implementation barriers related to these alternative intervention forms. In our qualitative study, we examined staff perceptions regarding the feasibility of implementing yoga along with established self-management at a pain management clinic in Colorado. We utilized the Implementation Drivers of Competency, Organizational, and Leadership, and our added Hypothetical Driver to explore barriers and facilitators related to project implementation. Our findings suggest that positive staff and patient attitudes were crucial for successful implementation. We also identified physical space, transportation, and supportive leadership as necessary components of project implementation. Further research is needed to examine barriers such as funding to ensure intervention sustainability and the need for adequate staffing.

    Multi-center trials provide the unique ability to investigate novel techniques across a range of geographical sites with sufficient statistical power, the inclusion of multiple operators determining feasibility under a wider array of clinical environments and work-flows. For this purpose, we introduce a new means of distributing pre-procedural cardiac models for image-guided interventions across a large scale multi-center trial. In this method, a single core facility is responsible for image processing, employing a novel web-based interface for model visualization and distribution. The requirements for such an interface, being WebGL-based, are minimal and well within the realms of accessibility for participating centers. We then demonstrate the accuracy of our approach using a single-center pacemaker lead implantation trial with generic planning models.

    High-quality nucleic acids are critical for optimal PCR-based diagnostics and pathogen detection. Rapid sample processing time is important for the earliest administration of therapeutic and containment measures, especially in the case of biothreat agents. In this context, we compared the Fujifilm QuickGene-Mini80 to Qiagen's QIAamp Mini Purification kits for extraction of DNA and RNA for potential use in austere settings. Qiagen (QIAamp) column-based extraction is the currently recommended purification platform by United States Army Medical Research Institute for Infectious Diseases for both DNA and RNA extraction. However, this sample processing system requires dedicated laboratory equipment including a centrifuge. In this study, we investigated the QuickGene-Mini80, which does not require centrifugation, as a suitable platform for nucleic acid extraction for use in resource-limited locations. Quality of the sample extraction was evaluated using pathogen-specific, real-time PCR assays for nucleic acids extracted from viable and γ-irradiated Bacillus anthracis, Yersinia pestis, vaccinia virus, Venezuelan equine encephalitis virus, or B. anthracis spores in buffer or human whole blood. QuickGene-Mini80 and QIAamp performed similarly for DNA extraction regardless of organism viability. It was noteworthy that γ-irradiation did not have a significant impact on real-time PCR for organism detection. Comparison with QIAamp showed a less than adequate performance of the Fujifilm instrument for RNA extraction. However, QuickGene-Mini80 remains a viable alternative to QIAamp for DNA extraction for use in remote settings due to extraction quality, time efficiency, reduced instrument requirements, and ease of use.

    Optimal management of HIV disease requires high levels of lifelong adherence once a patient initiates highly active antiretroviral therapy (HAART). Because suboptimal adherence to HAART is associated with adverse consequences, many providers are hesitant to prescribe HAART for patients whom they perceive as not being ready to initiate treatment. Accurately predicting HIV treatment readiness is challenging. Despite the importance of this construct, few reliable and valid instruments to assess HIV treatment readiness have been developed; none of these have been validated with adolescents and young adults, who comprise an increasing proportion of new HIV cases diagnosed. As a first step to achieve this goal, we developed the HIV Treatment Readiness Measure (HTRM) for administration via audio-computer-assisted self interview and conducted a study to examine its internal consistency, test-retest reliability, acceptability, and preliminary factor structure. We recruited 201 youth from 15 adolescent medicine clinics that were part of the Adolescent Trials Network for HIV Interventions. Youth completed the initial assessment and two weeks later the re-test assessment. The refined HTRM had high internal consistency (α = 0.84). Test-retest reliability using both sum scores and mean scores were high. The HTRM was also highly acceptable and feasible to use in routine clinical practice. In exploratory factor analysis we found that a five-factor solution was the best fit; each of the subscales (Disclosure, Psychosocial Issues, Connection with Care, HIV Medication Beliefs, Alcohol and Drugs) had good to acceptable alphas and eigenvalues greater than 2.0. Our findings support conducting a future study to examine the tool’s predictive validity. PMID:22022853

    Differential access to everyday technology and healthcare amongst safety net patients is associated with low technological and health literacies, respectively. These low rates of literacy produce a complex patient "knowledge gap" that influences the effectiveness of telehealth technologies. To understand this "knowledge gap", six focus groups (2 African-American and 4 Latino) were conducted with patients who received teleretinal screenings in U.S. urban safety-net settings. Findings indicate that patients' "knowledge gap" is primarily produced at three points: (1) when patients' preexisting personal barriers to care became exacerbated in the clinical setting; (2) through encounters with technology during screening; and (3) in doctor-patient follow-up. This "knowledge gap" can produce confusion and fear, potentially affecting patients' confidence in quality of care and limiting their disease management ability. In rethinking the digital divide to include the consequences of this knowledge gap faced by patients in the clinical setting, we suggest that patient education focus on both their disease and specific telehealth technologies deployed in care delivery.

    Personally owned handheld referencing technology such as smartphones or tablets, and the adjunct applications (apps) that can be used on them, are becoming a part of everyday life for the New Zealand population. In common with the population at large, student nurses have embraced this technology since the advent of the Apple iPhone in 2010. Little is known internationally or in New Zealand about the way student nurses may apply personally owned handheld referencing technology to their education process. The perceptions of New Zealand nurse managers, toward personally owned handheld referencing technology, could not be located. Using a qualitative descriptive methodology, semi structured interviews were conducted with New Zealand student nurses (n = 13), and nurse managers (n = 5) about their perceptions of use of personally owned handheld referencing technology as an educational tool in clinical settings. A thematic analysis was conducted on the resulting text. Student nurses said they wanted to use their own handheld referencing technology to support clinical decisions. Nurse managers perceived the use of personally owned handheld referencing technology as unprofessional, and do not trust younger cohorts of student nurses to act ethically when using this technology. This research supports historical research findings from the student perspective about the usefulness of older hand held referencing devices to augment clinical decisions. However, due to perceptions held by nurse mangers regarding professional behaviour, safety and the perceived institutional costs of managing personally owned handheld referencing technology, the practice may remain problematic in the studied setting.

    The increased use of Palladium (Pd) for biomedical applications, which has more than doubled in the last ten years, appears to be associated with an increased frequency of adverse reactions to Pd. The aim of this study is to investigate the relationship between the implant of a biomechanical apparatus containing Pd and the setting of a hypersensitivity to Pd by determining the levels of the metal released in biological fluids, assessing the effects of Pd on peripheral blood mononuclear cell (PBMC) cytokine production and exploring the clinical setting of skin sensitization. Of a total of 3,093 subjects examined in 2006, sensitization to Pd alone or in association with nickel (Ni) was observed in 1.6% and 13.03% of the individuals, respectively. Of these, a group of six subjects positive to Pd and negative to Ni at patch testing were selected on the basis of the oral clinical symptoms in order to measure both the levels of Pd in biological fluids and the degradation of the dental prostheses. Specific Pd measurements were carried out on salivary fluid, urine and serum samples by High Resolution Inductively Coupled Plasma-Mass Spectrometry. In addition, the degradation of the dental prostheses was assessed by both a leaching test and an analysis of the micro morphology of orthodontic prostheses. The induction of IFN-gamma production by Pd was assessed in PBMC by the ELISpot assay. Skin sensitization to Pd was evaluated by patch testing and clinical examination. Ten healthy subjects were comparatively tested as controls. We found a specific induction of an IFN-gamma response by Pd in PBMC collected from all the subjects positive to Pd at patch testing. On the contrary, control subjects did not show any response to Pd as assessed by IFN-gamma ELISpot assay or by skin testing. Remarkably, the levels of Pd in all biological samples (saliva, sera, urine) were significantly higher in Pd-sensitized patients than in those collected from controls, reaching the highest

    Purpose Increasing numbers of childhood cancer survivors are seen in primary care settings as young adults. It is unknown how their self-reported health problems differ from those of healthy young adults. Self-reported health problems of cancer survivors and healthy controls are compared in this study. Methods 156 cancer survivors visiting a cancer survivorship program and 138 controls in primary care centers (mean age of 20 years) completed the Health Knowledge Inventory (HKI), a checklist of 35 health problems. Results Cancer survivors reported significantly more health problems than healthy controls (5.6 vs 2.6 problems, p < .001). For cancer survivors, more intense treatment and older age related to Organic/Major problems and Constitutional/Other problems. Female gender related to report of Organic/Major and Constitutional/Other problems for the controls. While at least 20% of both healthy controls and survivors endorsed dermatologic, headache, gastrointestinal and weight problems, survivors endorsed growth, thyroid, kidney, immunological, heart, and fertility problems fourfold over controls. Conclusions Cancer survivors endorse significantly more health problems than healthy controls. However, some problems are reported with equal frequency among the groups. Understanding these similarities and differences between survivors and healthy controls will facilitate patient-centered comprehensive care for young adult cancer survivors. PMID:20453176

    Some antibiotics are reserved essentially for hospital settings owing to cost effectiveness and in order to fight the emerging antibiotic resistance crisis. In some cases, antibiotics reserved exclusively for use in hospitals may be prescribed in outpatients for serious infections or in the absence of a therapeutic alternative. A 30-day prospective audit of outpatient prescriptions of antibiotics reserved exclusively for use in hospitals was performed. The objective of this study was to evaluate the relevance of outpatient antibiotic prescriptions by measuring appropriateness according to guidelines. During the study period, 53 prescriptions were included, only 40% of which were appropriate. Among the 32 inappropriate prescriptions, 4 cases lacked microbial arguments, 1 case was not adequate for the infection type, 1 case involved an incorrect antibiotic dosage, 1 case involved an incorrect interval of dose administration, 3 cases had a therapeutic alternative and 22 cases were not recommended. Of the 53 prescriptions, 66% were started in hospital and 34% in outpatients. Only 25% of cases were prescribed with infectious diseases specialist (IDS) advice, 64% were based on microbiological documentation and 13% had a negative bacterial culture. Inappropriate prescriptions were usually observed in antibiotic lock therapy, skin infections, Clostridium difficile colitis, intra-abdominal infections and intravascular catheter-related infections. Outpatient prescriptions of antimicrobial drugs reserved exclusively for use in hospitals are frequently inappropriate. We recommend a real-time analysis algorithm with the involvement of an IDS for monitoring prescriptions to improve the quality of these prescriptions and possibly to prevent antibiotic resistance.

    18-Flurodeoxyglucose Positron Emission Tomography with computed tomography (FDG PET/CT) and Magnetic Resonance Imaging (MRI) have higher sensitivity and specificity than whole-body X-ray (WBXR) survey in evaluating disease extent in patients with multiple myeloma (MM). Both modalities are now recommended by the Durie-Salmon Plus classification although the emphasis is more on MRI than PET/CT. The presence of extra-medullary disease (EMD) as evaluated by PET/CT imaging, initial SUVmax and number of focal lesions (FL) are deemed to be strong prognostic parameters at staging. MRI remains the most sensitive technique for the detection of diffuse bone marrow involvement in both the pre and post-therapy setting. Compression fractures are best characterized with MRI signal changes, for determining vertebroplasty candidates. While PET/CT allows for earlier and more specific evaluation of therapeutic efficacy compared to MRI, when signal abnormalities persist years after treatment. PET/CT interpretation, however, can be challenging in the vertebral column and pelvis as well as in cases with post-therapy changes. Hence, a reading approach combining the high sensitivity of MRI and superior specificity of FDG PET/CT would be preferred to increase the diagnostic accuracy. In summary, the established management methods in MM, mainly relying on biological tumor parameters should be complemented with functional imaging data, both at staging and restaging for optimal management of MM.

    Natural childbirth has ceased to be considered the gold standard in the delivery room. For this reason cesarean section on demand is increasing. Many obstetricians justify this phenomenon on evidence-based obstetrical practice. However, other pieces of evidence demonstrate that the data are often a product of the social milieu, and as stated by Wendland, "technology magically wards off the unpredictability and danger of birth". In a recent paper, Kalish pointed out several problems with cesarean deliveries in the absence of medical indications regarding issues of good clinical practice, autonomy, and informed consent. From the late 1990s, the medical community began to speak in favor of women's autonomy in childbirth decisions thus supporting the maternal choice and request for a cesarean section. Starting from these new considerations, it is of primary importance to understand whether emphasizing patient's autonomy is the best, or the only, way to helping the medical decisional process. This general approach may be helpful in all the other cases in which patient's autonomy and physician's responsibility appear to be intertwined in an apparent conflicting manner. We fear that the rhetoric of autonomous choice represents a fundamental shift from medicine-based beneficence toward a perilous relationship founded mainly on patient's wishes, representing a dangerous slippery slope where the physician could be reduced to the role of a functionary delegated to execute patient's claims and demands.

    Despite the accessibility of the oral cavity to clinical examination, delays in diagnosis of oral and oropharyngeal carcinoma (OOPC) are observed in a large majority of patients, with negative impact on prognosis. Diagnostic aids might help detection and improve early diagnosis, but there remains little robust evidence supporting the use of any particular diagnostic technology at the moment. The aim of the present feasibility first-in-human study was to evaluate the preliminary diagnostic validity of a novel technology platform based on dielectrophoresis (DEP). DEP does not require labeling with antibodies or stains and it is an ideal tool for rapid analysis of cell properties. Cells from OOPC/dysplasia tissue and healthy oral mucosa were collected from 57 study participants via minimally-invasive brush biopsies and tested with a prototype DEP platform using median membrane midpoint frequency as main analysis parameter. Results indicate that the current DEP platform can discriminate between brush biopsy samples from cancerous and healthy oral tissue with a diagnostic sensitivity of 81.6% and a specificity of 81.0%. The present ex vivo results support the potential application of DEP testing for identification of OOPC. This result indicates that DEP has the potential to be developed into a low-cost, rapid platform as an assistive tool for the early identification of oral cancer in primary care; given the rapid, minimally-invasive and non-expensive nature of the test, dielectric characterization represents a promising platform for cost-effective early cancer detection.

    The efficacy of screening and brief intervention (SBI) for drug use in primary care patients is largely unknown. Because of this lack of evidence, US professional organizations do not recommend it. Yet, a strong theoretical case can be made for drug SBI. Drug use is common and associated with numerous health consequences, patients usually do not seek help for drug abuse and dependence, and SBI has proven efficacy for unhealthy alcohol use. On the other hand, the diversity of drugs of abuse and the high prevalence of abuse and dependence among those who use them raise concerns that drug SBI may have limited or no efficacy. Federal efforts to disseminate SBI for drug use are underway, and reimbursement codes to compensate clinicians for these activities have been developed. However, the discrepancies between science and policy developments underscore the need for evidence-based research regarding the efficacy of SBI for drug use. This article discusses the rationale for drug SBI and existing research on its potential to improve drug-use outcomes and makes the argument that randomized controlled trials to determine its efficacy are urgently needed to bridge the gap between research, policy, and clinical practice.

    Background The objective of our study was the development of a semi-quantitative real-time PCR to detect uropathogens. Two multiplex PCR reactions were designed to detect Escherichia coli, Klebsiella spp., Enterobacter spp., Citrobacter spp., Proteus mirabilis, Enterococcus faecalis, and Pseudomonas aeruginosa. 16S based PCR was performed in parallel to detect Gram-positive and Gram-negative bacteria. Firstly to identify non-targeted agents of infection in the same urine specimen, and secondly to quantify background flora. The method was evaluated in comparison with standard bacterial culture, and a commercial PCR kit for detection of uropathogens. Findings Analysis with a known panel of 116 clinical isolates yielded a PCR specificity of 100%. Analysis of urine specimens from 211 patients revealed a high correlation of PCR Cq values with both culture positivity and quantity. Concordance between PCR and culture was 98% when both methods yielded results. PCR was found to be more sensitive than culture. With a cut-off Cq value of 33, the negative predictive value of PCR was 94%. The 16S PCR confirmed most results. One specimen was positive by 16S PCR suggesting another cause of infection not detected by the specific PCR assays. Conclusion We conclude that it is feasible to detect and identify uropathogens by multiplex real-time PCR assay. PMID:26954694

    WHAT IS KNOWN ON THE SUBJECT?: Panic disorder patients display various panic-related physical symptoms and catastrophic misinterpretation of bodily sensations, which lower their quality of life by interfering with daily activities. Cognitive behavioural therapy (CBT) is a useful strategy for panic disorder patients to manage symptoms associated with inaccurate cognitive interpretation of situations resulting from the patient's cognitive vulnerability. In South Korea, however, despite the increasing prevalence of panic disorder, CBT is not a common element of nursing care plans for panic disorder patients. Moreover, few Korean researchers have attempted to assess the effects of CBT on such patients. WHAT THIS PAPER ADD TO EXISTING KNOWLEDGE?: In a strategy combining CBT and routine treatments, patients with panic disorder can experience greater positive effects in the acute treatment phase than those they experience when receiving only routine treatment. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Mental health professionals, especially psychiatric nurses in local clinics who operate most special mental health programmes for panic disorder patients, should apply a panic disorder management programme that integrates CBT and routine treatments. The integrated approach is more effective for reducing the number of panic attacks and cognitive misinterpretation in patients than providing routine treatment alone. For patients with panic disorder, the objective of CBT is to understand the relationship between psychological panic disorder sensations, emotions, thoughts and behaviours. Therefore, nurses can help patients address and improve biological, social and psychological aspects of physical health problems as well as help them improve their coping skills in general.

  11. Teaching communication skills in clinical settings: comparing two applications of a comprehensive program with standardized and real patients

    2014-01-01

    Background Communication is important for the quality of clinical practice, and programs have been implemented to improve healthcare providers’ communication skills. However, the consistency of programs teaching communication skills has received little attention, and debate exists about the application of acquired skills to real patients. This study inspects whether (1) results from a communication program are replicated with different samples, and (2) results with standardized patients apply to interviews with real patients. Methods A structured, nine-month communication program was applied in two consecutive years to two different samples of healthcare professionals (25 in the first year, 20 in the second year). Results were assessed at four different points in time, each year, regarding participants’ confidence levels (self-rated), basic communication skills in interviews with standardized patients, and basic communication skills in interviews with real patients. Data were analyzed using GLM Repeated-Measures procedures. Results Improvements were statistically significant in both years in all measures except in simulated patients’ assessment of the 2008 group. Differences between the two samples were non-significant. Differences between interviews with standardized and with real patients were also non-significant. Conclusions The program’s positive outcomes were replicated in different samples, and acquired skills were successfully applied to real-patient interviews. This reinforces this type of program structure as a valuable training tool, with results translating into real situations. It also adds to the reliability of the assessment instruments employed, though these may need adaptation in the case of real patients. PMID:24886341

    The Children's Communication Checklist (CCC) was developed to provide an objective assessment of pragmatic aspects of children's communication difficulties. We aimed to (1) see whether the checklist provided valid and reliable information when completed by parents, and (2) consider its usefulness in a clinical context. Checklists were completed by parents and a professional who knew the child well for all 5 to 17-year-old referrals to a tertiary developmental paediatrics centre over a 31-month period. Children who were not yet speaking in sentences were excluded. From a sample of 151 children (81% male; mean age 8.7 years) with pervasive or specific developmental disorders, valid checklists were completed by 119 parents and 93 professionals. Reliability, as measured by internal consistency, was 0.7 or higher for most scales. Correlations between ratings for parents and professionals were in the range of 0.30 to 0.58 for individual pragmatic scales, with a correlation of 0.46 (n=82) for the pragmatic composite. For both parents and professionals, the pragmatic composite was lowest for children with a diagnosis of autism; intermediate for those with a diagnosis of Asperger syndrome, pervasive developmental disorder not otherwise specified or attention-deficit-hyperactivity disorder (ADHD); and highest for those with a diagnosis of specific learning disability. The strongest relation between the pragmatic composite and diagnosis was seen when ratings from parents and professionals were combined. Differences between diagnostic groups were not explicable in terms of age or verbal IQ.

    Although simple and low-cost interventions for sickle cell disease (SCD) exist in many developing countries, child mortality associated with SCD remains high, in part, because of the lack of access to diagnostic tests for SCD. A density-based test using aqueous multiphase systems (SCD-AMPS) is a candidate for a low-cost, point-of-care diagnostic for SCD. In this paper, the field evaluation of SCD-AMPS in a large (n = 505) case-control study in Zambia is described. Of the two variations of the SCD-AMPS used, the best system (SCD-AMPS-2) demonstrated a sensitivity of 86% (82–90%) and a specificity of 60% (53–67%). Subsequent analysis identified potential sources of false positives that include clotting, variation between batches of SCD-AMPS, and shipping conditions. Importantly, SCD-AMPS-2 was 84% (62–94%) sensitive in detecting SCD in children between 6 months and 1 year old. In addition to an evaluation of performance, an assessment of end-user operability was done with health workers in rural clinics in Zambia. These health workers rated the SCD-AMPS tests to be as simple to use as lateral flow tests for malaria and HIV. PMID:25490722

    There is insufficient evidence of the usefulness of dengue diagnostic tests under routine conditions. We sought to analyse how physicians are using dengue diagnostics to inform research and development. Subjects attending 14 health institutions in an endemic area of Colombia with either a clinical diagnosis of dengue or for whom a dengue test was ordered were included in the study. Patterns of test-use are described herein. Factors associated with the ordering of dengue diagnostic tests were identified using contingency tables, nonparametric tests and logistic regression. A total of 778 subjects were diagnosed with dengue by the treating physician, of whom 386 (49.5%) were tested for dengue. Another 491 dengue tests were ordered in subjects whose primary diagnosis was not dengue. Severe dengue classification [odds ratio (OR) 2.2; 95% confidence interval (CI) 1.1-4.5], emergency consultation (OR 1.9; 95% CI 1.4-2.5) and month of the year (OR 3.1; 95% CI 1.7-5.5) were independently associated with ordering of dengue tests. Dengue tests were used both to rule in and rule out diagnosis. The latter use is not justified by the sensitivity of current rapid dengue diagnostic tests. Ordering of dengue tests appear to depend on a combination of factors, including physician and institutional preferences, as well as other patient and epidemiological factors. PMID:25993399

    PubMed

    Oja, Kenneth J

    2011-03-01

    In preparation for the progressive nature of today's acute care hospital environments and the requirements for safe and effective patient care, it is essential that nursing students learn how to think critically. Problem-based learning is a method of education designed to encourage critical thinking. This article examines the evidence regarding the use of problem-based learning to improve critical thinking. A review of published literature was conducted using the CINAHL, ERIC, PsychInfo, and PubMed databases with the keywords nursing, problem-based learning, and critical thinking. Although the evidence is still accumulating, the studies reviewed indicate a positive relationship between problem-based learning and improved critical thinking in nursing students. There is a need for more rigorous research on the use of problem-based learning to examine the effects on critical thinking. Until this occurs, nursing instructors must rely on the extant evidence to guide their practice or continue to use the traditional model of clinical nursing education.

    Introduction. International comparative research on traditional medicine (TM) offers a useful method for examining differences in patient characteristics and can provide insight into: (i) more universal characteristics which may cross cultures and international borders; (ii) unique characteristics influenced by regional/national factors; and (iii) cultural values of immigrant populations. To explore these issues TM patients from the United States and China were compared. Methods. Data collection took place at two TM college clinics. A convenience sample of 128 patients in China and 127 patients in the United States completed a 28-item questionnaire. Results. There was a marked similarity between the two patient groups in terms of the biological characteristics of age and gender. Musculoskeletal issues were the most common presenting complaints in the United States; while in China TM was used for a more diverse array of conditions. The majority of patients in both countries had initially used allopathic medicine (AM); significantly, more of the United States respondents stopped allopathic treatment after beginning traditional treatment. In comparing the two countries, patients in China were significantly more satisfied with AM and American patients significantly more satisfied with TM. In comparing the two medicines, the patient samples in both countries were significantly more satisfied with TM than AM. Discussion. Although treatment often originated with allopathic providers, many patients sought alternatives presumably to find the best solution to their problems. This tendency toward self-assignment suggests that a pluralistic healthcare system may provide the greatest satisfaction resulting from personal choice and improved outcomes. PMID:18955368

    The objective of this clinical study was to investigate changes in levels of biomarkers of exposure (BOEs) in healthy Japanese male smokers who switched to a prototype heated cigarette (HC). This was a controlled, semi-randomized, open-label, residential study conducted in Japan. A total of 70 healthy Japanese male smokers were enrolled. Following enrollment, subjects smoked their usual brand of cigarette for 2days and were subsequently randomized either to an HC group or a 10mg tar conventional cigarette (CC10) group for four consecutive weeks. Levels of BOEs for ten selected cigarette smoke constituents (nicotine, carbon monoxide (CO), benzene, 1,3-butadiene, acrolein, hydrogen cyanide, crotonaldehyde, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone [NNK], pyrene, 4-aminobiphenyl), and urine mutagenicity were measured at several time points during the study period. At the end of the study period, except for blood carboxyhemoglobin, levels of BOEs for the other nine constituents and urine mutagenicity were significantly lower in the HC group compared to the CC10 group. These results suggest that exposure to most cigarette smoke constituents, except CO, can be reduced by switching from CC10 to HC.

    Essential hypertension is the most common noncommunicable disease (NCD), affecting more than half the adult population in many countries and being the major NCD contributor to the double burden of disease in developing countries. We undertook a survey of the hypertension awareness, treatment, and control in primary and secondary referral health care clinics in Enugu, Nigeria, and compared these data with those obtained in local community surveys. The prevalence of hypertension in the primary care clinic (9.2%) was lower than in a previously reported community survey (42.2%), while, in the referral clinic, 70.3% of patients attending were hypertensive. Hypertension awareness rates were 91.9%, 29.4%, and 93.2% in these respective health care settings. Treatment and control rates (89.9% and 72.9%) were better in the secondary care clinic than in the primary care centre (87.7% and 46.0%). (Chi-square analysis confirmed statistically significant differences between these rates (p < 0.05).) These data may form a useful index of health care system effectiveness in Nigeria. Possible reasons for the differences observed and effective strategies to address the waxing pandemic of hypertension are discussed. PMID:28050277

    The body of literature on the correlations between molecular assessments and patient outcomes after treatment with epidermal growth factor receptor (EGFR) inhibitors continues to grow. It will be important in the future to determine how to most effectively integrate molecular assays that assess the likelihood of therapeutic benefit into clinical practice. Although EGFR-targeted therapies such as erlotinib have been approved for use without molecular testing, immunohistochemistry, fluorescence in situ hybridization, and mutational analyses of the EGFR gene have all been proposed as candidates to help predict response or survival benefit from EGFR-targeted therapy in patients with non-small-cell lung cancer (NSCLC). Further prospective validation from ongoing randomized studies will be needed to fully determine which assays are best to help predict patient outcome. In addition, it will be critical for these assays to undergo standardization before widespread clinical use. The Molecular Assays in NSCLC Working Group, under the sponsorship of Genentech Inc, Roche Pharmaceuticals, and OSI Pharmaceuticals, Inc, was convened to evaluate the available molecular assays for use in the clinical trial setting and provide recommendations for application and interpretation of these tests for future clinical trials. Recommendations of the Molecular Assays in NSCLC Working Group for the use of EGFR molecular assays are presented and include guidelines for tissue storage, handling, and processing. Recommendations for the standardization of molecular assays are also discussed.

    Objective To achieve consensus on the most important outcome domains to measure across all clinical trials for shoulder disorders. Methods We performed an online modified Delphi study with an international, multidisciplinary and multistakeholder panel. A literature review and the OMERACT Filter 2.0 framework was used to generate a list of potential core domains, which were presented to patients, clinicians and researchers in two Delphi rounds. Participants were asked to judge the importance of each potential core domain and provide a rationale for their response. A core domain was defined a priori as a domain that at least 67% of participants considered core. Results In both rounds, 335 individuals were invited to participate (268 clinicians/researchers and 67 patients); response rates were 27% (n=91) and 29% (n=96), respectively. From a list of 41 potential core domains, four domains met our criteria for inclusion: ‘pain’, ‘physical functioning’, ‘global assessment of treatment success’ and ‘health-related quality of life’. Two additional domains, ‘sleep functioning’ and ‘psychological functioning’, met the criteria for inclusion by some, but not all stakeholder groups. There was consensus that ‘number of deaths’ was not a core domain, but insufficient agreement on whether or not several other domains, including ‘range of motion’ and ‘muscle strength’, were core domains. Conclusions Based on international consensus from patients, clinicians and researchers, ‘pain’, ‘physical functioning’, ‘global assessment of treatment success’ and ‘health-related quality of life’ were considered core outcome domains for shoulder disorder trials. The value of several other domains needs further consideration. PMID:28123775

  1. Validation of a Cochlear Implant Patient-Specific Model of the Voltage Distribution in a Clinical Setting

    Cochlear Implants (CIs) are medical implantable devices that can restore the sense of hearing in people with profound hearing loss. Clinical trials assessing speech intelligibility in CI users have found large intersubject variability. One possibility to explain the variability is the individual differences in the interface created between electrodes of the CI and the auditory nerve. In order to understand the variability, models of the voltage distribution of the electrically stimulated cochlea may be useful. With this purpose in mind, we developed a parametric model that can be adapted to each CI user based on landmarks from individual cone beam computed tomography (CBCT) scans of the cochlea before and after implantation. The conductivity values of each cochlea compartment as well as the weighting factors of different grounding modes have also been parameterized. Simulations were performed modeling the cochlea and electrode positions of 12 CI users. Three models were compared with different levels of detail: a homogeneous model (HM), a non-patient-specific model (NPSM), and a patient-specific model (PSM). The model simulations were compared with voltage distribution measurements obtained from the backward telemetry of the 12 CI users. Results show that the PSM produces the lowest error when predicting individual voltage distributions. Given a patient-specific geometry and electrode positions, we show an example on how to optimize the parameters of the model and how to couple it to an auditory nerve model. The model here presented may help to understand speech performance variability and support the development of new sound coding strategies for CIs. PMID:27933290

    Laboratory diagnosis and clinical management of inpatients with diarrhoea is complex and time consuming. Tests are often requested sequentially and undertaken in different laboratories. This causes prolonged unnecessary presumptive isolation of patients, because most cases are non-infectious. A molecular multiplex test (Luminex(®) Gastrointestinal Pathogen Panel (GPP)) was compared with conventional testing over 8 months to determine diagnostic accuracy, turnaround times, laboratory costs, use of isolation facilities and user acceptability. A total of 262 (12%) patients had a pathogen detected by conventional methods compared with 483 (22.1%) by GPP. Most additional cases were detected in patients developing symptoms in the first 4 days of admission. Additional cases were detected because of presumed improved diagnostic sensitivity but also because clinicians had not requested the correct pathogen. Turnaround time (41.8 h) was faster than bacterial culture (66.5 h) and parasite investigation (66.5 h) but slower than conventional testing for Clostridium difficile (17.3 h) and viruses (27 h). The test could allow simplified requesting by clinicians and a consolidated laboratory workflow, reducing the overall number of specimens received by the laboratory. A total of 154 isolation days were saved at an estimated cost of £30 800. Consumables and labour were estimated at £150 641 compared with £63 431 for conventional testing. Multiplex molecular testing using a panel of targets allowed enhanced detection and a consolidated laboratory workflow. This is likely to be of greater benefit to cases that present within the first 4 days of hospital admission.

    Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a rare cardiac disease characterized by myocardial fibrofatty replacement, which can lead to sudden death. Previous studies have described a reduction of plakoglobin (PKG) protein at the level of intercalated disks as the hallmark of ARVC. The main objective of this study was to investigate the involvement of desmosome mutations in the histological phenotype of ARVC. We performed a genetic analysis of ARVC cases, and histological characterization of ARVC heart tissue samples. We genetically analyzed 48 ARVC cases distributed into two groups: 42 human tissue heart samples with conclusive diagnoses of ARVC after post-mortem examination; and six DNA samples from peripheral blood of living patients who were clinically diagnosed. Sequenom MassARRAY analysis revealed three ARVC-associated variants in three patients in 42 tissue samples (7.14 %). Three individuals carried one single pathogenic mutation, p.R811S _PKP2, p.S824L_DSC2, and p.T526M_PKP2 in postmortem samples. In the living patients group, Sequenom MassARRAY revealed no mutation, however, later Sanger sequencing analysis identified three ARVC mutations in 2/6 patients not included in the Sequenom design. In post-mortem tissue samples we performed immunohistochemical labeling for desmosomal proteins and Connexin 43. This study revealed that PKP2 carriers present either absent or clearly reduced PKG immunolabeling, while the DSC2 carrier showed PKG immunolabeling similar to control samples. Immunolabeling for Cx43 did not show any differences compared to controls. The present Sequenom MassARRAY design is a useful tool for post-mortem genetic diagnosis of ARVC. Plakoglobin reduction occurs at intercalated disks, while other desmosome proteins and Cx43 remain unaltered.

    At three months and at one year following completion of a formal training course in laparoscopic urologic surgery, course participants were surveyed as to their interim laparoscopic experience. Data regarding practice setting, subspecialization, course attendance (alone or with a partner), nature and training of surgical assistant, and additional training subsequent to the course was collected. These variables were then correlated with information on the number and nature of surgical complications encountered subsequent to the course. In the three months following course completion, surgeons who performed clinical procedures without additional training were 3.39 times more likely to have at least one complication compared to surgeons who sought additional training (p equals 0.030). One year following course completion surgeons who had attended the training course alone, were in solo practice, or performed laparoscopic surgery with a variable assistant, were, respectively, 4.85, 7.74, and 4.80 times more likely to have had a complication than their counterparts who attend the course with a partner, were in group practice, or who operated with the same assistant (p equals 0.004, p equals 0.001, and p equals 0.002). At both three months and one year following training, laparoscopic complication rates of individual surgeons (number of complications/number of cases) demonstrated a highly significant inverse correlation with the number of laparoscopic procedures performed. These data suggest that the rate of complications associated with the clinical `learning' curve can be decreased by additional education following an initial course in laparoscopy. An ongoing clinical association with surgeons performing similar procedures appears to decrease long-term complication rates. Findings from this study argue for the regulation of the clinical application of new surgical skills acquired in the post-residency setting, and maintenance of the new skills through continuing

    Background Many studies have provided evidence of the importance of quality provider-patient communications and have suggested improvements to patient understanding by using video-based instruction. Objective The objective of this study was to understand how mobile information technology assisted video and three-dimensional (3D) image instruction, provided by a health care worker, influences two categories of outcome: (1) patient understanding of information about their condition and detailed medical discharge instructions; and (2) patient perceptions and attitudes toward their health care providers, which included physicians, nurses, and staff. We hypothesize that video and 3D image instruction, provided on a mobile, tablet hardware platform, will improve patient understanding about the diagnostic testing, diagnoses, procedures, medications, and health topics provided to them. We also propose that use of the tablet/video combination will result in improved attitudinal evaluation by patients of their providers and the treatment plan. Methods This study evaluated a hospital clinic-based trial (patient N=284) of video and 3D image instruction, provided on a mobile, tablet hardware platform, and its potential to improve patient understanding about the diagnostic testing, diagnoses, procedures, medications, and health topics provided to them. Results Results showed strong evidence that the system was perceived as helpful for improving patient understanding, and that it improved communication between physicians and patients (P<.001). The advanced age of some patients had no effect on their perceptions of the tablet-based mediation. Physician comments provided useful insights on effective use of such systems in the future. Implications for further development and future research are discussed. Conclusions This study added to the body of evidence that computer-assisted video instructional systems for patients can improve patient understanding of medical instructions from

    Introduction The primary purpose of this study is to evaluate the relative effectiveness of 2 of the best developed and most promising forms of therapy for problem gambling, namely face-to-face motivational interviewing (MI) combined with a self-instruction booklet (W) and follow-up telephone booster sessions (B; MI+W+B) and face-to-face cognitive–behavioural therapy (CBT). Methods and analysis This project is a single-blind pragmatic randomised clinical trial of 2 interventions, with and without the addition of relapse-prevention text messages. Trial assessments take place pretreatment, at 3 and 12 months. A total of 300 participants will be recruited through a community treatment agency that provides services across New Zealand and randomised to up to 10 face-to-face sessions of CBT or 1 face-to-face session of MI+W+up to 5 B. Participants will also be randomised to 9 months of postcare text messaging. Eligibility criteria include a self-perception of having a current gambling problem and a willingness to participate in all components of the study (eg, read workbook). The statistical analysis will use an intent-to-treat approach. Primary outcome measures are days spent gambling and amount of money spent per day gambling in the prior month. Secondary outcome measures include problem gambling severity, gambling urges, gambling cognitions, mood, alcohol, drug use, tobacco, psychological distress, quality of life, health status and direct and indirect costs associated with treatment. Ethics and dissemination The research methods to be used in this study have been approved by the Ministry of Health, Health and Disability Ethics Committees (HDEC) 15/CEN/99. The investigators will provide annual reports to the HDEC and report any adverse events to this committee. Amendments will also be submitted to this committee. The results of this trial will be submitted for publication in peer-reviewed journals and as a report to the funding body. Additionally, the results

    2011-01-01

    Background Physicians involved in primary prevention are key players in CVD risk control strategies, but the expected reduction in CVD risk that would be obtained if all patients attending primary care had their risk factors controlled according to current guidelines is unknown. The objective of this study was to estimate the excess risk attributable, firstly, to the presence of CVD risk factors and, secondly, to the lack of control of these risk factors in primary prevention care across Europe. Methods Cross-sectional study using data from the European Study on Cardiovascular Risk Prevention and Management in Daily Practice (EURIKA), which involved primary care and outpatient clinics involved in primary prevention from 12 European countries between May 2009 and January 2010. We enrolled 7,434 patients over 50 years old with at least one cardiovascular risk factor but without CVD and calculated their 10-year risk of CVD death according to the SCORE equation, modified to take diabetes risk into account. Results The average 10-year risk of CVD death in study participants (N = 7,434) was 8.2%. Hypertension, hyperlipidemia, smoking, and diabetes were responsible for 32.7 (95% confidence interval 32.0-33.4), 15.1 (14.8-15.4), 10.4 (9.9-11.0), and 16.4% (15.6-17.2) of CVD risk, respectively. The four risk factors accounted for 57.7% (57.0-58.4) of CVD risk, representing a 10-year excess risk of CVD death of 5.66% (5.47-5.85). Lack of control of hypertension, hyperlipidemia, smoking, and diabetes were responsible for 8.8 (8.3-9.3), 10.6 (10.3-10.9), 10.4 (9.9-11.0), and 3.1% (2.8-3.4) of CVD risk, respectively. Lack of control of the four risk factors accounted for 29.2% (28.5-29.8) of CVD risk, representing a 10-year excess risk of CVD death of 3.12% (2.97-3.27). Conclusions Lack of control of CVD risk factors was responsible for almost 30% of the risk of CVD death among patients participating in the EURIKA Study. PMID:21923932

    Despite progress against intimate partner violence (IPV) and HIV/AIDS in the past two decades, both epidemics remain major public health problems, particularly among women of color. The objective of this study was to assess the relationship between recent IPV and HIV risk factors (sexual and drug risk behaviors, STIs, condom use and negotiation) among women of African descent. We conducted a comparative case-control study in women’s health clinics in Baltimore, Maryland and St. Thomas and St. Croix, US Virgin Islands (USVI). Women aged 18–55 years who experienced physical and/or sexual IPV in the past two years (Baltimore, n=107; USVI, n=235) were compared to women who never experienced any form of abuse (Baltimore, n=207; USVI, n=119). Logistic regression identified correlates of recent IPV by site. In both sites, having a partner with concurrent sex partners was independently associated with a history of recent IPV (Baltimore, AOR: 3.91, 95% CI:1.79–8.55 and USVI, AOR: 2.25, 95% CI:1.11–4.56). In Baltimore, factors independently associated with recent IPV were lifetime casual sex partners (AOR: 1.99, 95% CI: 1.11–3.57), exchange sex partners (AOR: 5.26, 95% CI:1.92–14.42), infrequent condom use during vaginal sex (AOR: 0.24, 95% CI:0.08–0.72), and infrequent condom use during anal sex (AOR: 0.29, 95% CI:0.09–0.93). In contrast, in the USVI, having a concurrent sex partner (AOR: 3.33, 95% CI:1.46–7.60), frequent condom use during vaginal sex (AOR: 1.97, 95% CI:1.06–3.65), frequent condom use during anal sex (AOR: 6.29, 95% CI:1.57–25.23), drug use (AOR: 3.16, 95% CI:1.00–10.06), and a past-year STI (AOR: 2.68, 95% CI:1.25–5.72) were associated with recent IPV history. The divergent results by site warrant further investigation into the potential influence of culture, norms, and intentions on the relationships examined. Nonetheless, study findings support a critical need to continue the development and implementation of culturally tailored

    A study was made of the antimicrobial susceptibility to and efficacy of various kinds of antimicrobial agents against 179 strains of Pseudomonas aeruginosa that were isolated from blood cultures at Kansai Medical University Hospital from 1990 through 2004. The annual detection rate was highest in 1994, at 22 strains (6.5%). There were 9 multidrug resistant strains of Pseudomonas aeruginosa (5.0%). Among 14 antimicrobial agents tested for measurements, ciprofloxacin (CPFX) showed the best minimum inhibitory concentration (MIC) 50 value, of 0.25 microg/ml, followed by pazufloxacin (PZFX) and biapenem (BIPM), each at 0.5 microg/ml. When the period of 15 years was divided into three stages, the MIC50 value for each antimicrobial agent was highest in the middle stage (1995 to 1999). Assuming that the percentage of sensitive strains according to the breakpoints set by the Clinical and Laboratory Standards Institute (CLSI) represents the antimicrobial susceptibility rate, amikacin (AMK) showed the best value, of 85.5%. According to the sepsis breakpoint set by the Japanese Society of Chemotherapy (JSC), the efficacy of CPFX showed the highest rate (77.1%) of all the antimicrobial agents tested. Among beta-lactams, BIPM showed the highest efficacy rate, of 67.0%. When the efficacy rates were compared with each other, the difference in efficacy rate between the breakpoint set by the CLSI and the sepsis breakpoint set by the JSC was large for beta-lactams. Comparisons made based on the CLSI criteria showed no difference in cross-resistance rates between CPFX, meropenem (MEPM), and BIPM. However, when comparisons were made using the JSC sepsis breakpoint, MEPM showed a cross-resistance rate of 87.8%, while the rate for BIPM was lower, at 56.1%, with the chi2 test showing a significant difference, at P = 0.0014. In accordance with the pharmacokinetics/pharmacodynamics theory that has been advocated, breakpoints which are more suitable for the clinical setting in Japan should

    Creatinine in urine is a useful biochemical parameter to correct the urinary excretion rate of endogenous and exogenous substances. Nitrite (ONO(-)) and nitrate (ONO2(-)) are metabolites of nitric oxide (NO), a signalling molecule with multiple biological functions. Under certain and standardized conditions, the concentration of nitrate in the urine is a suitable measure of whole body NO synthesis. The urinary nitrate-to-nitrite molar ratio (UNOxR) may indicate nitrite-dependent renal carbonic anhydrase (CA) activity. In clinical studies, urine is commonly collected by spontaneous micturition. In those cases the nitrate and nitrite excretion must be corrected for creatinine excretion. Pentafluorobenzyl (PFB) bromide (PFB-Br) is a useful derivatization reagent of numerous inorganic and organic compounds, including urinary nitrite, nitrate and creatinine, for highly sensitive and specific quantitation by GC-MS. Here, we report on the simultaneous PFB-Br derivatization (60min, 50°C) of ONO(-), O(15)NO(-), ONO2(-), O(15)NO2(-), creatinine (do-Crea) and [methylo-(2)H3]creatinine (d3-Crea) in acetonic dilutions of native human urine and plasma samples (4:1, v/v) and their simultaneous quantification by GC-MS as PFBNO2, PFB(15)NO2, PFBONO2, PFBO(15)NO2, do-Crea-PFB and d3-Crea-PFB, respectively. Electron capture negative-ion chemical ionization (ECNICI) of these derivatives generates anions due to [M-PFB](-), i.e., the starting analytes. Quantification is performed by selected-ion monitoring (SIM) of m/z 46 (ONO(-)), m/z 47 (O(15)NO(-)), m/z 62 (ONO2(-)), m/z 63 (O(15)NO2(-)), m/z 112 (do-Crea), and m/z 115 (d3-Crea). Retention times were 2.97min for PFB-ONO2/PFB-O(15)NO2, 3.1min for PFB-NO2/PFB-(15)NO2, and 6.7min for do-Crea-PFB/d3-Crea-PFB. We used this method to investigate the effects of long-term oral NaNO3 or NaCl (serving as placebo) supplementation (each 0.1mmol/kg body weight per day for 3 weeks) on creatinine excretion and UNOxR in 17 healthy young men

    The implementation of hybrid imaging systems requires thorough and anticipatory planning at local and regional levels. For installation of combined positron emission and magnetic resonance imaging systems (PET/MRI), a number of physical and constructional provisions concerning shielding of electromagnetic fields (RF- and high-field) as well as handling of radionuclides have to be met, the latter of which includes shielding for the emitted 511 keV gamma rays. Based on our experiences with a SIEMENS Biograph mMR system, a step-by-step approach is required to allow a trouble-free installation. In this article, we present a proposal for a standardized step-by-step plan to accomplish the installation of a combined PET/MRI system. Moreover, guidelines for the smooth operation of combined PET/MRI in an integrated research and clinical setting will be proposed. Overall, the most important preconditions for the successful implementation of PET/MRI in an integrated research and clinical setting is the interdisciplinary target-oriented cooperation between nuclear medicine, radiology, and all referring and collaborating institutions at all levels of interaction (personnel, imaging protocols, reporting, selection of the data transfer and communication methods).

    Conducting clinical trials in developing countries often presents significant ethical, organisational, cultural and infrastructural challenges to researchers, pharmaceutical companies, sponsors and regulatory bodies. Globally, these regions are under-represented in research, yet this population stands to gain more from research in these settings as the burdens on health are greater than those in developed resourceful countries. However, developing countries also offer an attractive setting for clinical trials because they often have larger treatment naive populations with higher incidence rates of disease and more advanced stages. These factors can present a reduction in costs and time required to recruit patients. So, balance needs to be found where research can be encouraged and supported in order to bring maximum public health benefits to these communities. The difficulties with such trials arise from problems with obtaining valid informed consent, ethical compensation mechanisms for extremely poor populations, poor health infrastructure and considerable socio-economic and cultural divides. Ethical concerns with trials in developing countries have received attention, even though many other non-ethical issues may arise. Local investigator initiated trials also face a variety of difficulties that have not been adequately reported in literature. This paper uses the example of the Cameroon Mobile Phone SMS trial to describe in detail, the specific difficulties encountered in an investigator-initiated trial in a developing country. It highlights administrative, ethical, financial and staff related issues, proposes solutions and gives a list of additional documentation to ease the organisational process.

    Rationale Clinical trial design in interstitial lung diseases (ILDs) has been hampered by lack of consensus on appropriate outcome measures for reliably assessing treatment response. In the setting of connective tissue diseases (CTDs), some measures of ILD disease activity and severity may be confounded by non-pulmonary comorbidities. Methods The Connective Tissue Disease associated Interstitial Lung Disease (CTD-ILD) working group of Outcome Measures in Rheumatology—a non-profit international organisation dedicated to consensus methodology in identification of outcome measures—conducted a series of investigations which included a Delphi process including >248 ILD medical experts as well as patient focus groups culminating in a nominal group panel of ILD experts and patients. The goal was to define and develop a consensus on the status of outcome measure candidates for use in randomised controlled trials in CTD-ILD and idiopathic pulmonary fibrosis (IPF). Results A core set comprising specific measures in the domains of lung physiology, lung imaging, survival, dyspnoea, cough and health-related quality of life is proposed as appropriate for consideration for use in a hypothetical 1-year multicentre clinical trial for either CTD-ILD or IPF. As many widely used instruments were found to lack full validation, an agenda for future research is proposed. Conclusion Identification of consensus preliminary domains and instruments to measure them was attained and is a major advance anticipated to facilitate multicentre RCTs in the field. PMID:24368713

    Background: In the past two decades vascular closure devices (VCD) have been increasingly utilized as an alternative to manual compression after percutaneous femoral artery access. However, there is a lack of data confirming a significant reduction of vascular complication in a routine interventional setting. Systematic assessment of puncture sites with ultrasound was hardly performed. Methods: 620 consecutive patients undergoing elective or urgent percutaneous coronary intervention were randomly allocated to either Angioseal (AS; n = 210), or Starclose (SC; n = 196) or manual compression (MC; n = 214). As an adjunct to clinical evaluation vascular ultrasonography was used to assess the safety of each hemostatic method in terms of major and minor vascular complications. The efficacy of VCDs was assessed by achievement of puncture site hemostasis. Results: No major complications needing transfusion or vascular surgery were observed. Furthermore, the overall incidence of clinical and subclinical minor complications was similar among the three groups. There was no differences in the occurrence of pseudoaneurysmata (AS = 10; SC = 6; MC = 10), arteriovenous fistula (AS = 1; SC = 4; MC = 2) and large hematoma (AS = 11; SC = 10; MC = 14). The choice of access site treatment had no impact in the duration of hospital stay (AS = 6.7; SC = 7.4; MS = 6.4 days). Conclusions: In the setting of routine coronary intervention AS and SC provide a similar efficacy and safety as manual compression. Subclinical vascular injuries are rare and not related to VCD use.

    Purpose: To evaluate the clinical potential of deformable image registration (DIR)-based automatic propagation of physician-drawn contours from a planning CT to midtreatment CT images for head and neck (H and N) adaptive radiotherapy. Methods: Ten H and N patients, each with a planning CT (CT1) and a subsequent CT (CT2) taken approximately 3–4 week into treatment, were considered retrospectively. Clinically relevant organs and targets were manually delineated by a radiation oncologist on both sets of images. Four commercial DIR algorithms, two B-spline-based and two Demons-based, were used to deform CT1 and the relevant contour sets onto corresponding CT2 images. Agreement of the propagated contours with manually drawn contours on CT2 was visually rated by four radiation oncologists in a scale from 1 to 5, the volume overlap was quantified using Dice coefficients, and a distance analysis was done using center of mass (CoM) displacements and Hausdorff distances (HDs). Performance of these four commercial algorithms was validated using a parameter-optimized Elastix DIR algorithm. Results: All algorithms attained Dice coefficients of >0.85 for organs with clear boundaries and those with volumes >9 cm{sup 3}. Organs with volumes <3 cm{sup 3} and/or those with poorly defined boundaries showed Dice coefficients of ∼0.5–0.6. For the propagation of small organs (<3 cm{sup 3}), the B-spline-based algorithms showed higher mean Dice values (Dice = 0.60) than the Demons-based algorithms (Dice = 0.54). For the gross and planning target volumes, the respective mean Dice coefficients were 0.8 and 0.9. There was no statistically significant difference in the Dice coefficients, CoM, or HD among investigated DIR algorithms. The mean radiation oncologist visual scores of the four algorithms ranged from 3.2 to 3.8, which indicated that the quality of transferred contours was “clinically acceptable with minor modification or major modification in a small number of contours

    Background There are very few effective, scientifically validated treatments with known mechanisms of action for treatment of hair loss in both men and women. Fibroblast growth factor 5 (FGF5) is an important factor in the irreversible transition from anagen to catagen, and inhibition of FGF5 prolongs anagen phase and reduces hair loss. Objective We aimed to screen botanically derived molecules for FGF5 inhibitory activity in vitro and assess efficacy in a clinical setting. Methods We screened for FGF5 inhibitory efficacy via a novel 2-step in vitro pipeline consisting of an engineered FGF5 responsive cell line, followed by an activated dermal papillae (DP) cell method. Efficacy in a clinical setting was assessed in a randomized, single-blind, placebo-controlled trial against early- to mid-stage pattern hair loss in men and women. Results We observed FGF5 inhibitory activity for a number of compounds from the monoterpenoid family, many showing greater inhibitory efficacy than our previously reported crude plant extracts. Evaluation of a lead candidate in a clinical study over 112 days showed a significant improvement in anagen:telogen (AT) ratio (p = 0.002), reduced hair fall (p = 0.007) and improved visual grading (p = 0.004). Scientifically matched photography on a subgroup of randomly chosen participants highlighted significant improvement in hair density, with increases evident in all tested participants compared to baseline. Conclusion Isolates from the monoterpenoid family displayed efficacy in FGF5 inhibition in vitro. A topical formulation containing a leading isolate significantly improved AT ratio, reduced hair fall and increased apparent hair density in the tested population of men and women. PMID:28280377

In response, the International Rescue Committee developed a multimedia training tool to encourage competent, compassionate, and confidential clinical care for sexual assault survivors in low-resource settings. This study evaluated the effect of the training on healthcare providers’ attitudes, knowledge, confidence, and practices in four countries. Methods Using a mixed-methods approach, we surveyed a purposive sample of 106 healthcare providers before and 3 months after training to measure attitudes, knowledge, and confidence. In-depth interviews with 40 providers elaborated on survey findings. Medical record audits were conducted in 35 health facilities before and 3 months after the intervention to measure healthcare providers’ practice. Quantitative and qualitative data underwent statistical and thematic analysis. Results While negative attitudes, including blaming and disbelieving women who report sexual assault, did not significantly decrease among healthcare providers after training, respect for patient rights to self-determination and non-discrimination increased from 76% to 91% (p < .01) and 74% to 81% (p < .05) respectively. Healthcare providers’ knowledge and confidence in clinical care for sexual assault survivors increased from 49% to 62% (p < .001) and 58% to 73% (p < .001) respectively following training. Provider practice improved following training as demonstrated by a documented increase in eligible survivors receiving emergency contraception from 50% to 82% (p < .01), HIV post-exposure prophylaxis from 42% to 92% (p < .001), and STI prophylaxis and treatment from 45% to 96% (p < .01). Conclusions Although beliefs about sexual assault are hard to change, training can improve healthcare providers

    The current study describes the development of a set of 5 multiplex polymerase chain reaction (mPCR) assays for the simultaneous detection of abortive infection agents in bovine fetal tissues, including Brucella spp., Leptospira spp., and Campylobacter fetus (mPCR1); Hammondia heydorni, Neospora caninum, and Toxoplasma gondii (mPCR2); Coxiella burnetii and Chlamydophila psittaci (mPCR3); Mycoplasma bovis, Mycoplasma bovigenitalium, and Ureaplasma diversum (mPCR4); and Bovine viral diarrhea virus (BVDV) and Bovine herpesvirus-1 (BoHV-1; mPCR5). The protocol was tested on different tissue samples collected from 50 aborted bovine fetuses, and it showed that out of the 50 fetuses, 7 (14%, mPCR2) were PCR-positive for N. caninum, 4 (8%, mPCR5) were PCR-positive for BVDV, and 2 (4%, mPCR4) were PCR-positive for U. diversum. The results obtained by using each multiplex PCR were 100% concordant with those obtained by using the respective PCR assays targeting single genes on the same specimens. Moreover, all multiplex PCR assays on clinical samples were compared with reference methods, obtaining a perfect accordance in all samples and confirming the validity of the set of multiplex PCR assays. The proposed set of multiplex PCR assays is, therefore, suitable for the simultaneous detection of the main infectious agents responsible for bovine abortion.

    Background The effectiveness of psoriasis therapies in real-world settings remains relatively unknown. Objective To compare the effectiveness of less commonly used systemic monotherapies and commonly used combination therapies for psoriasis. Methods Multi-center cross-sectional study of 203 patients with plaque psoriasis receiving less common systemic monotherapy (acitretin, cyclosporine, or infliximab) or common combination therapies (adalimumab, etanercept, or infliximab and methotrexate) compared to 168 patients receiving methotrexate evaluated at one of ten US outpatient dermatology sites participating in the Dermatology Clinical Effectiveness Research Network. Results In adjusted analyses, patients on acitretin (relative response rate 2.01; 95% confidence interval, 1.18–3.41), infliximab (1.93; 1.26–2.98), adalimumab and methotrexate (3.04; 2.12–4.36), etanercept and methotrexate (2.22; 1.25–3.94), and infliximab and methotrexate (1.72; 1.10–2.70) were more likely to have clear or almost clear skin compared to patients on methotrexate. There were no differences among treatments when response rate was defined by health-related quality of life. Limitations Single time point assessment may result in overestimation of effectiveness. Conclusions The efficacy of therapies in clinical trials may overestimate their effectiveness as utilized in clinical practice. While physician-reported relative response rates were different among therapies, absolute differences were small and did not correspond to differences in patient-reported outcomes. PMID:25260564

    Background The prognostic and predictive significance of the high-level microsatellite instability (MSI-H) phenotype in various malignancies is unclear. We describe the characteristics, clinical course, and outcomes of patients with MSI-H malignancies treated in a real-life hospital setting. Patients and methods A retrospective analysis of MSI-H cancer patient files was conducted. We analyzed the genetic data, clinical characteristics, and oncological treatments, including chemotherapy and surgical interventions. Results Clinical data of 73 MSI-H cancer patients were available. Mean age at diagnosis of first malignancy was 52.3 years. Eight patients (11%) had more than four malignancies each. Most patients (76%) had colorectal cancer (CRC). Seventeen patients (23%) had only extracolonic malignancies. Eighteen women (36%) had gynecological malignancy. Nine women (18%) had breast cancer. Mean follow-up was 8.5 years. Five-year overall survival and disease-free survival of all MSI-H cancer patients from first malignancy were 86% and 74.6%, respectively. Five-year overall survival rates of stage 2, 3, and 4 MSI-H CRC patients were 89.5%, 58.4%, and 22.9%, respectively. Conclusion Although the overall prognosis of MSI-H cancer patients is favorable, this advantage may not be maintained in advanced MSI-H CRC patients.

    Objectives Introducing new programming into an existing setting may be challenging. Understanding how staff and clinicians who are not directly involved in program delivery view the program can help support program implementation. This study aimed to understand how peripheral staff and clinicians perceived a newly implemented Centering Pregnancy group prenatal care program in a community-based health center and its impact on clinic operations. Methods Semi-structured interviews were conducted with a purposive sample of 12 staff members at a community-based health center. The interview guide covered topics such as perceptions of Centering Pregnancy and how the program impacted their work. An interpretive description approach was used to analyze the interview data. A coding framework was developed iteratively and all interview data were analyzed independently by multiple researchers. Results Staff had overall positive perceptions of Centering Pregnancy, but the level of understanding about the program varied widely. Most respondents viewed the Centering Pregnancy program as separate from other programs offered by the clinic, which created both opportunities and challenges. Opportunities included increased cross-referrals between established services and Centering Pregnancy. Challenges included a lack of communication about responsibilities of staff in relation to Centering Pregnancy patients. Impact on staff and overall clinic operations was perceived to be minimal to moderate, and most tensions related to roles and expectations were resolved. Conclusions for Practice Clear communication regarding fit within clinic structures and processes and expectations of staff in relation to the program was critical to the integration of Centering Pregnancy program into an established health center.

    Background The aim of this study was to evaluate to what extent laboratory data, actual medication, medical history, and/or drug indication influence the quality of medication reviews for nursing home patients. Methods Forty-six health care professionals from different fields were requested to perform medication reviews for three different cases. Per case, the amount of information provided varied in three subsequent stages: stage 1, medication list only; stage 2, adding laboratory data and reason for hospital admission; and stage 3, adding medical history/drug indication. Following a slightly modified Delphi method, a multidisciplinary team performed the medication review for each case and stage. The results of these medication reviews were used as reference reviews (gold standard). The remarks from the participants were scored, according to their potential clinical impact, from relevant to harmful on a scale of 3 to −1. A total score per case and stage was calculated and expressed as a percentage of the total score from the expert panel for the same case and stage. Results The overall mean percentage over all cases, stages, and groups was 37.0% when compared with the reference reviews. For one of the cases, the average score decreased significantly from 40.0% in stage 1, to 30.9% in stage 2, and 27.9% in stage 3; no significant differences between stages was found for the other cases. Conclusion The low performance, against the gold standard, of medication reviews found in the present study highlights that information is incorrectly used or wrongly interpreted, irrespective of the available information. Performing medication reviews without using the available information in an optimal way can have potential implications for patient safety. PMID:26056459

  3. A preliminary study of individual cognitive behavior therapy for social anxiety disorder in Japanese clinical settings: a single-arm, uncontrolled trial

    2013-01-01

    Background Cognitive behavior therapy (CBT) is regarded as an effective treatment for social anxiety disorder (SAD) in Europe and North America. Individual CBT might be acceptable and effective for patients with SAD even in non-Western cultures; therefore, we conducted a feasibility study of individual CBT for SAD in Japanese clinical settings. We also examined the baseline predictors of outcomes associated with receiving CBT. Methods This single-arm trial employed a 14-week individual CBT intervention. The primary outcome was the self-rated Liebowitz Social Anxiety Scale, with secondary measurements of other social anxiety and depressive severity. Assessments were conducted at baseline, after a waiting period before CBT, during CBT, and after CBT. Results Of the 19 subjects screened, 15 were eligible for the study and completed the outcome measures at all assessment points. Receiving CBT led to significant improvements in primary and secondary SAD severity (ps < .001). The mean total score on the Liebowitz Social Anxiety Scale improved from 91.8 to 51.7 (before CBT to after CBT), and the within-group effect size at the end-point assessment was large (Cohen’s d = 1.71). After CBT, 73% of participants were judged to be treatment responders, and 40% met the criteria for remission. We found no significant baseline predictors of those outcomes. Conclusion Despite several limitations, our treatment—which comprises a 14-week, individual CBT program—seems feasible and may achieve favorable treatment outcomes for SAD in Japanese clinical settings. Further controlled trials are required in order to address the limitations of this study. Trial registration UMIN-CTR UMIN000005897 PMID:23448435

    To address the burden of maternal morbidity and mortality in low- and middle-income countries (LMICs), research with pregnant women in these settings is increasingly common. Pregnant women in LMIC-context may experience vulnerability related to giving consent to participate in a clinical trial. To recognize possible layers of vulnerability this study aims to identify factors that influence the decision process towards clinical trial participation of pregnant women in an urban middle-income setting. This qualitative research used participant observation, in-depth interviews, and focus group discussion with medical staff and pregnant women eligible for trial participation, at a regional hospital in Accra, Ghana. Besides lack of familiarity with modern scientific concepts, specific factors influencing the decision-making process were identified. These include a wide power difference between health provider and patient, and a different perception of risk through externalization of responsibility of risk management within a religious context as well as a context shaped by authority. Also, therapeutic misconception was observed. The combination of these factors ensued women to rely on the opinion of the medical professional, rather than being guided by their own motivation to participation. Although being a (pregnant) woman per se should not render the label of being vulnerable, this study shows there are factors that influence the decision process of pregnant woman towards trial participation in a LMIC context that can result in vulnerability. The identification of context-specific factors that can create vulnerability facilitates adaptation of the design and conduct of research in a culturally competent manner.

    The Institute of Medicine's (IOM's) 2011 report on the health of LGBT people pointed out that there are limited health data on these populations and that we need more research. It also described what we do know about LGBT health disparities, including lower rates of cervical cancer screening among lesbians, and mental health issues related to minority stress. Patient disclosure of LGBT identity enables provider-patient conversations about risk factors and can help us reduce and better understand disparities. It is essential to the success of Healthy People 2020's goal of eliminating LGBT health disparities. This is why the IOM's report recommended data collection in clinical settings and on electronic health records (EHRs). The Center for Medicare and Medicaid Services and the Office of the National Coordinator of Health Information Technology rejected including sexual orientation and gender identity (SOGI) questions in meaningful use guidelines for EHRs in 2012 but are considering this issue again in 2013. There is overwhelming community support for the routine collection of SOGI data in clinical settings, as evidenced by comments jointly submitted by 145 leading LGBT and HIV/AIDS organizations in January 2013. Gathering SOGI data in EHRs is supported by the 2011 IOM's report on LGBT health, Healthy People 2020, the Affordable Care Act, and the Joint Commission. Data collection has long been central to the quality assurance process. Preventive health care from providers knowledgeable of their patients' SOGI can lead to improved access, quality of care, and outcomes. Medical and nursing schools should expand their attention to LGBT health issues so that all clinicians can appropriately care for LGBT patients.

    More than 2 million children globally are living with HIV infection and >90% of these reside in sub-Saharan Africa. Severe acute malnutrition (SAM) remains a major problem for HIV-infected children who live in resource-limited settings (RLS), and SAM is an important risk factor for mortality. SAM in HIV-infected children is associated with complications including electrolyte disorders, micronutrient deficiencies, and severe infections, which contribute to the high mortality. Access to antiretroviral therapy (ART) has significantly improved the survival of HIV-infected children, although the response to ART of children with SAM remains undocumented in the literature. Immune and virologic responses to ART in RLS are similar to those of infected children in resource-rich settings, but delays in initiation of therapy have led to a high early mortality. Antiretroviral drug toxicities have been described in children who receive therapy and may affect their quality of life and long-term survival. Metabolic complications of ART include lipodystrophy, dyslipidemia, lactic acidosis, insulin resistance, and osteopenia. These complications have been well described in adults and children from developed countries, but data from RLS are limited, and these complications may be compounded by SAM. In this article we review the epidemiology, clinical presentation, and complications of SAM in HIV-infected children and the metabolic complications of HIV-infected children in the era of ART, and discuss future research priorities for RLS.

    The usefulness of combined anti-HCV and 24 mini-pool HCV RNA screening strategy was re-evaluated after a six-year continuous routine use in a clinical virology laboratory, at which more than half of newly diagnosed hepatitis C patients are intravenous drug users. Pools of 24 samples were prepared from 20,448 anti-HCV negative serum samples and tested using an automated commercial PCR assay with a lower limit of detection of 50 IU/ml. After detection of anti-HCV negative/HCV RNA positive patients, responsible physicians provided follow-up samples. Thirty-eight (0.19%) anti-HCV negative/HCV RNA positive samples from 30 patients (28 intravenous drug users) were detected. Follow-up samples were available for 27/30 patients. Twenty, six and one patient seroconverted in the second, third and fourth available samples, respectively. The interval between the first HCV RNA positive and the first available anti-HCV positive sample was 17-517 days. The costs of detecting a single anti-HCV negative/HCV RNA positive patient were 1227 Euros. Combined anti-HCV and 24 mini-pool HCV RNA screening is a useful and cost effective strategy, not only in blood-transfusion settings but also in a routine clinical virology laboratory, at which a significant proportion of the tested population belongs to a high-risk population.

    Tumor hypoxia is recognized as a limiting factor for the efficacy of radiotherapy, because it enhances tumor radioresistance. It is strongly suggested that assessing tumor oxygenation could help to predict the outcome of cancer patients undergoing radiation therapy. Strategies have also been developed to alleviate tumor hypoxia in order to radiosensitize tumors. In addition, oxygen mapping is critically needed for intensity modulated radiation therapy (IMRT), in which the most hypoxic regions require higher radiation doses and the most oxygenated regions require lower radiation doses. However, the assessment of tumor oxygenation is not yet included in day-to-day clinical practice. This is due to the lack of a method for the quantitative and non-invasive mapping of tumor oxygenation. To fully integrate tumor hypoxia parameters into effective improvements of the individually tailored radiation therapy protocols in cancer patients, methods allowing non-invasively repeated, safe, and robust mapping of changes in tissue oxygenation are required. In this review, non-invasive methods dedicated to assessing tumor oxygenation with the ultimate goal of predicting outcome in radiation oncology are presented, including positron emission tomography used with nitroimidazole tracers, magnetic resonance methods using endogenous contrasts (R1 and R2*-based methods), and electron paramagnetic resonance oximetry; the goal is to highlight results of studies establishing correlations between tumor hypoxic status and patients’ outcome in the preclinical and clinical settings.

    The general population has a pessimistic view of low back pain (LBP), and evidence-based information has been used to positively influence LBP beliefs in previously reported mass media studies. However, there is a lack of randomized trials investigating whether LBP beliefs can be modified in primary prevention settings. This cluster randomized clinical trial investigated the effect of an evidence-based psychosocial educational program (PSEP) on LBP beliefs for soldiers completing military training. A military setting was selected for this clinical trial, because LBP is a common cause of soldier disability. Companies of soldiers (n = 3,792) were recruited, and cluster randomized to receive a PSEP or no education (control group, CG). The PSEP consisted of an interactive seminar, and soldiers were issued the Back Book for reference material. The primary outcome measure was the back beliefs questionnaire (BBQ), which assesses inevitable consequences of and ability to cope with LBP. The BBQ was administered before randomization and 12 weeks later. A linear mixed model was fitted for the BBQ at the 12-week follow-up, and a generalized linear mixed model was fitted for the dichotomous outcomes on BBQ change of greater than two points. Sensitivity analyses were performed to account for drop out. BBQ scores (potential range: 9-45) improved significantly from baseline of 25.6 +/- 5.7 (mean +/- SD) to 26.9 +/- 6.2 for those receiving the PSEP, while there was a significant decline from 26.1 +/- 5.7 to 25.6 +/- 6.0 for those in the CG. The adjusted mean BBQ score at follow-up for those receiving the PSEP was 1.49 points higher than those in the CG (P < 0.0001). The adjusted odds ratio of BBQ improvement of greater than two points for those receiving the PSEP was 1.51 (95% CI = 1.22-1.86) times that of those in the CG. BBQ improvement was also mildly associated with race and college education. Sensitivity analyses suggested minimal influence of drop out. In conclusion, soldiers

  17. Whiteheadian Actual Entitities and String Theory

    NASA Astrophysics Data System (ADS)

    Bracken, Joseph A.

    2012-06-01

    In the philosophy of Alfred North Whitehead, the ultimate units of reality are actual entities, momentary self-constituting subjects of experience which are too small to be sensibly perceived. Their combination into "societies" with a "common element of form" produces the organisms and inanimate things of ordinary sense experience. According to the proponents of string theory, tiny vibrating strings are the ultimate constituents of physical reality which in harmonious combination yield perceptible entities at the macroscopic level of physical reality. Given that the number of Whiteheadian actual entities and of individual strings within string theory are beyond reckoning at any given moment, could they be two ways to describe the same non-verifiable foundational reality? For example, if one could establish that the "superject" or objective pattern of self- constitution of an actual entity vibrates at a specific frequency, its affinity with the individual strings of string theory would be striking. Likewise, if one were to claim that the size and complexity of Whiteheadian 'societies" require different space-time parameters for the dynamic interrelationship of constituent actual entities, would that at least partially account for the assumption of 10 or even 26 instead of just 3 dimensions within string theory? The overall conclusion of this article is that, if a suitably revised understanding of Whiteheadian metaphysics were seen as compatible with the philosophical implications of string theory, their combination into a single world view would strengthen the plausibility of both schemes taken separately. Key words: actual entities, subject/superjects, vibrating strings, structured fields of activity, multi-dimensional physical reality.

    Purpose: To measure and compare the performance of X-ray imaging detectors in a clinical setting using a dedicated instrument for the quantitative determination of detector performance. Methods: The DQEPro (DQE Instruments Inc., London, Ontario Canada) was used to determine the MTF, NPS and DQE using an IEC compliant methodology for three different imaging modalities: conventional radiography (CsI-based detector), general-purpose radioscopy (CsI-based detector), and mammography (a-Se based detector). The radiation qualities (IEC) RQA-5 and RQA-M-2 were used for the CsI-based and a-Se-based detectors, respectively. The DQEPro alleviates some of the difficulties associated with DQE measurements by automatically positioning test devices over the detector, guiding the user through the image acquisition process and providing software for calculations. Results: A comparison of the NPS showed that the image noise of the a-Se detector was less correlated than the CsI detectors. A consistently higher performance was observed for the a-Se detector at all spatial frequencies (MTF: 0.97@0.25 cy/mm, DQE: 0.72@0.25 cy/mm) and the DQE drops off slower than for the CsI detectors. The CsI detector used for conventional radiography displayed a higher performance at low spatial frequencies compared to the CsI detector used for radioscopy (DQE: 0.65 vs 0.60@0.25 cy/mm). However, at spatial frequencies above 1.3 cy/mm, the radioscopy detector displayed better performance than the conventional radiography detector (DQE: 0.35 vs 0.24@2.00 cy/mm). Conclusion: The difference in the MTF, NPS and DQE that was observed for the two different CsI detectors and the a-Se detector reflect the imaging tasks that the different detector types are intended for. The DQEPro has made the determination and calculation of quantitative metrics of X-ray imaging detector performance substantially more convenient and accessible to undertake in a clinical setting.

  19. The feasibility of implementing an evidence-based core set of clinical pharmacy services in 2020: manpower, marketplace factors, and pharmacy leadership.

    Development of a national plan to implement a core set of clinical pharmacy services in United States hospitals by 2020 requires assertive leadership from pharmacy organizations and state boards of pharmacy, and a commitment from the profession. Factors that may affect the development are grouped into three areas: manpower, marketplace variables, and pharmacy leadership. Although the number of pharmacy school graduates (7000) was about the same in 1990 and 2000, a greater number of pharmacy schools and high student enrollment, coupled with the Accreditation Council for Pharmacy Education's acceptance of foreign-trained pharmacists, suggest that the number of pharmacists will increase substantially in the near future. We estimate that the net increase in pharmacists (new pharmacy graduates less pharmacists who retire or die) in the United States will be 139,929 from 2000-2020, for a total of 335,040 pharmacists (71% increase). The number of pharmacy technicians increased substantially (66%), from 150,000 in 1996 to 250,000 in 2002. The number of residents in programs accredited by the American Society of Health-System Pharmacists increased 148%, from 435 in 1990 to 1080 in 2002. We conservatively project an increase of 33,000 pharmacists who complete residencies from 2000-2020. The pharmacy marketplace has changed dramatically over the last 12 years, with 10,754 independent community pharmacies closing (2.46 pharmacies/day) and 8459 chain outlets opening (1.93 chains/day). In recent years, mail-order pharmacies have expanded faster than other retail outlets and now process over 18% of U.S. prescriptions. Increased use of robotic systems (some can process 5000 prescriptions/hr) and technicians will diminish the demand for dispensing pharmacists. In addition, up to 10% of U.S. retail prescriptions may be filled outside the country's borders. These data indicate that there will be a sufficient supply of pharmacists and technicians in the future. Thus, it is feasible

    Objectives To project the clinical and economic outcomes of a genotype assay for selection of third-line antiretroviral therapy (ART) in resource-limited settings, as per the planned international A5288 trial (MULTI-OCTAVE). Methods We used the Cost-effectiveness of Preventing AIDS Complications (CEPAC)-International Model to compare three strategies for subjects who have failed second-line ART in South Africa: (1) Sustained second-line: no genotype assay, all subjects remain on second-line ART; (2) A5288: genotype to determine the resistance profile and assign an appropriate regimen; or (3) Population-based third-line: no genotype, all subjects switch to a potent third-line regimen. Model inputs are from published data in South Africa. Resistance profiles, ART regimens, and efficacy data were those used for trial planning. Results Projected life expectancy for sustained second-line, A5288, and population-based third-line are 61.1, 103.8, and 104.2 months. Compared to sustained second-line ($12,460), per person lifetime costs increase for the A5288 ($39,250) and population-based ($44,120) strategies. The incremental cost-effectiveness ratio of A5288, compared to sustained second-line, is $7,500/year of life saved (YLS), and for population-based third-line, compared to A5288, is $154,500/YLS. In the A5288 strategy, very late presentation to care, coupled with lengthy delays to obtain the genotype, dramatically reduces 5-yr survival, making the population-based third-line strategy more attractive. Conclusions We project that, while the public health approach to third-line therapy is unaffordable, genotype assays and third-line ART in resource-limited settings will increase survival and be cost-effective compared to the population-based approach, supporting the value of an efficacy study.

    Neoliberal emphasis on "responsibility" has colonized many aspects of public life, including how health care is provided. Clinical risk assessment of patients based on a range of data concerned with lifestyle, behavior, and health status has assumed a growing importance in many health systems. It is a mechanism whereby responsibility for self (preventive) care can be shifted to patients, provided that risk assessment data is communicated to patients in a way which is engaging and motivates change. This study aimed to look at whether the form in which tailored risk information was presented in a clinical setting (for example, using photographs, online data, diagrams etc.), was associated with differences in patients' responses and preferences to the material presented. We undertook a systematic review using electronic searching of nine databases, along with handsearching specialist journals and backward and forward citation searching. We identified eleven studies (eight with a randomized controlled trial design). Seven studies involved the use of computerized health risk assessments in primary care. Beneficial effects were relatively modest, even in studies merely aiming to enhance patient-clinician communication or to modify patients' risk perceptions. In our paper, we discuss the apparent importance of the accompanying discourse between patient and clinician, which appears to be necessary in order to impart meaning to information on "risk," irrespective of whether the material is personalized, or even presented in a vivid way. Thus, while expanding computer technologies might be able to generate a highly personalized account of patients' risk in a time efficient way, the need for face-to-face interactions to impart meaning to the data means that these new technologies cannot fully address the resource issues attendant with this type of approach.

    We investigated the occurrence, diversity and molecular epidemiology of genes coding for acquired AmpC β-lactamases (qAmpC) among clinical isolates of Enterobacteriaceae lacking inducible chromosomal AmpCs in Portugal. A total of 675 isolates non-susceptible to broad-spectrum cephalosporins obtained from four hospitals and three community laboratories during a 7-year period (2002-2008) were analysed. The presence of genes coding for qAmpC was investigated by phenotypic criteria, polymerase chain reaction (PCR) and sequencing. Bacterial identification, antibiotic susceptibility testing, conjugation assays and clonal analysis were performed by standard procedures. The presence of bla(qAmpC) genes was detected in 50 % (50/100; 41 Klebsiella pneumoniae, 5 Escherichia coli, 4 Klebsiella oxytoca) of the presumptive qAmpC producers. DHA-1, detected in those species, was the most prevalent qAmpC (94 %, 47/50), being identified since 2003 and throughout the studied period in different institutions. Despite the high clonal diversity observed, three DHA-1-producing Klebsiella spp. clones were more frequently identified. CMY-2 (6 %, 3/50) was observed in B1-E. coli clones. Conjugative transfer was only observed in one (2 %) CMY-2-producing isolate. Most qAmpC producers (94 %, 47/50) co-expressed SHV-type and/or OXA-1 or CTX-M-32 extended-spectrum β-lactamases (ESBLs). To the authors' knowledge, this is the first description of the molecular epidemiology and the long-term dissemination of qAmpC-producing Enterobacteriaceae in Portuguese clinical settings, highlighting an evolution towards a more complex epidemiological situation regarding cephalosporin resistance in Portugal.

    Objectives To evaluate the influence of the practice setting on diagnostic accuracy of fractional exhaled nitric oxide (FENO) for diagnosing asthma; and to develop prediction rules for diagnostic decision-making including clinical signs and symptoms (CSS). Setting Patients from 10 general practices and 1 private practice of 5 pneumologists in ambulatory care. Participants 553 patients, 57.9% female. Consecutive inclusion of diagnostic-naive patients suspected of suffering from obstructive airway disease. Exclusion criteria were respiratory tract infections within the last 6 weeks. Interventions The index test was FENO measurement. Reference standard was the Tiffeneau ratio (forced expiratory volume in 1 s/vital capacity) or airway resistance as assessed by whole body plethysmography, with additional bronchoprovocation or bronchodilator testing. Primary and secondary outcome measures Asthma as determined by pneumologists, who were blind to FENO measurement results. Prediction rules were derived from multiple logistic regression analysis. A freely available calculator that allows computing all combinations was developed. Results The practice setting only had minor influence on sensitivities of FENO cut-off points. In the final model (n=472), allergic rhinitis, wheezing and previous medication were positively associated with asthma. Increasing age and recurrent respiratory tract infections were negatively associated. The area under the curve (AUC) of FENO (AUC=0.650; 95% CI 0.599 to 0.701) increased significantly (p<0.0001) when combined with CSS (AUC=0.753; 95% CI 0.707 to 0.798). Presence of wheezing and allergic rhinitis allowed ruling in asthma with FENO >30 ppb. Ruling out with FENO <16 ppb in patients <43 years was only possible without allergic symptoms when recurrent respiratory tract infections were present. Conclusions FENO results should be interpreted in the context of CSS to enhance their diagnostic value in primary care. The final diagnostic

    The usefulness of peanut specific IgE levels for diagnosing peanut allergy has not been studied in primary and secondary care where most cases of suspected peanut allergy are being evaluated. We aimed to determine the relationship between peanut-specific IgE levels and clinical peanut allergy in peanut-sensitized children and how this was influenced by eczema, asthma and clinical setting (primary or secondary care). We enrolled 280 children (0-18 years) who tested positive for peanut-specific IgE (> 0.35 kU/L) requested by primary and secondary physicians. We used predefined criteria to classify participants into three groups: peanut allergy, no peanut allergy, or possible peanut allergy, based on responses to a validated questionnaire, a detailed food history, and results of oral food challenges.Fifty-two participants (18.6%) were classified as peanut allergy, 190 (67.9%) as no peanut allergy, and 38 (13.6%) as possible peanut allergy. The association between peanut-specific IgE levels and peanut allergy was significant but weak (OR 1.46 for a 10.0 kU/L increase in peanut-specific IgE, 95% CI 1.28-1.67). Eczema was the strongest risk factor for peanut allergy (aOR 3.33, 95% CI 1.07-10.35), adjusted for demographic and clinical characteristics. Asthma was not significantly related to peanut allergy (aOR 1.93, 95% CI 0.90-4.13). Peanut allergy was less likely in primary than in secondary care participants (OR 0.46, 95% CI 0.25-0.86), at all levels of peanut-specific IgE.The relationship between peanut-specific IgE and peanut allergy in children is weak, is strongly dependent on eczema, and is weaker in primary compared to secondary care. This limits the usefulness of peanut-specific IgE levels in the diagnosis of peanut allergy in children.

    Cohesive polydensified matrix (CPM®) hyaluronic acid fillers are now available with or without lidocaine. The aim of this study was to investigate the safety and performance of CPM® fillers with lidocaine in the clinical setting. In an open-label, prospective, postmarketing study, 108 patients from seven sites in Germany and Denmark were treated with one or more lidocaine-containing CPM® fillers. Performance was assessed using the Merz Aesthetics Scales® (MAS). Pain was rated on an 11-point visual analog scale. Patients’ and physicians’ satisfaction as well as adverse events were recorded. Improvements of ≥1-point on MAS immediately after and 17 days posttreatment were observed in ~90% of patients compared with baseline. All investigators assessed ejection force, product positioning, and performance as similar or superior to the respective nonlidocaine products. Overall, 94% of investigators were satisfied with the esthetic outcomes and were willing to continue using the products. All patients except one were satisfied with the results, and all were willing to repeat the treatment. Mean pain scores were low during (<3.0) and after injection (<0.6). Except for one case of bruising, all adverse events were mild to moderate. CPM® fillers with lidocaine are safe and effective for a wide range of esthetic facial indications. PMID:27799807

    Background. This study aimed to assess the relationship between illness perception and depressive symptoms among persons with diabetes. Method. This was an analytical cross-sectional study conducted among 379 type 2 diabetic patients from three major clinical settings of Kathmandu, Nepal. Results. The prevalence of depressive symptoms was 44.1% (95% CI: 39.1, 49.1). Females (p < 0.01), homemakers (p < 0.01), 61-70 age group (p = 0.01), those without formal education (p < 0.01), and people with lower social status (p < 0.01) had significantly higher proportion of depressive symptoms than the others. Multivariable analysis identified age (β = 0.036, p = 0.016), mode of treatment (β = 0.9, p = 0.047), no formal educational level (β = 1.959, p = 0.01), emotional representation (β = 0.214, p < 0.001), identity (β = 0.196, p < 0.001), illness coherence (β = -0.109, p = 0.007), and consequences (β = 0.093, p = 0.049) as significant predictors of depressive symptoms. Conclusion. Our study demonstrated a strong relationship between illness perception and depressive symptoms among diabetic patients. Study finding indicated that persons living with diabetes in Nepal need comprehensive diabetes education program for changing poor illness perception, which ultimately helps to prevent development of depressive symptoms.

    A major challenge to implementing precision medicine is the need for an efficient and cost-effective strategy for returning individual genomic test results that is easily scalable and can be incorporated into multiple models of clinical practice. My46 is a web-based tool for managing the return of genetic results that was designed and developed to support a wide range of approaches to results disclosure, ranging from traditional face-to-face disclosure to self-guided models. My46 has five key functions: set and modify results return preferences, return results, educate, manage return of results, and assess return of results. These key functions are supported by six distinct modules and a suite of features that enhance the user experience, ease site navigation, facilitate knowledge sharing, and enable results return tracking. My46 is a potentially effective solution for returning results and supports current trends toward shared decision-making between patient and provider and patient-driven health management.

    The purpose of this study was to compare the effect of traditional learning and cooperative learning methods on nursing students' communication skill with patients. This was an experimental study in which 34 nursing students in their 2nd semester of program participated. They were divided randomly into two groups, a control group who were taught their medical/surgical nursing course by traditional learning method and an experimental group, who were taught the same material using cooperative learning method. Before and after the teaching intervention, the students' communication skills with patients at clinical settings were examined. The results showed that no significant difference between the two groups in students' communication skills scores before the teaching intervention, but did show a significant difference between the two groups in the interaction skills and problem follow up sub-scales scores after the teaching intervention. This study provides evidence that cooperative learning is an effective method for improving and increasing communication skills of nursing students especially in interactive skills and follow up the problems sub-scale, thereby it is recommended to increase nursing students' participation in arguments by applying active teaching methods which can provide the opportunity for increased communication skills.

    We analyze the impact of HIV rapid testing (RT) programs in non-clinical settings (NCS) by evaluating their contribution to new diagnoses reported to the Spanish HIV Surveillance System (SINIVIH) from 2007 to 2012. We estimate the proportion of new diagnoses reported to SINIVIH attributable to them and the maximum annual contribution (MAC). Of 95.575 rapid tests conducted, 2061 were reactive; 1582 in men who have sex with men (MSM). The contribution of RT in NCS increased from 3.4% in 2007 to 11.0% in 2012 (8.1%-16.6% in MSM). RT programs contributed 25.3% of the new diagnoses reported in Catalonia (MAC:30.6%), 15% in the Canary Islands (MAC:16.2%) and 13.7% in the Basque Country (MAC:21.0%). Among MSM, contribution was of 45.2% in Catalonia (MAC:60.7%), 20.2% in the Canary Islands (MAC:21.3%) and 16.6% in the Basque country (MAC:20.9%). Especially among MSM, RT in NCS contributed a large proportion of the new HIV cases diagnosed in regions with a very high HIV incidence.

    The primary goal of this observational clinical study was to register the occurrence of incorrect inflation and deflation timing of an intra-aortic balloon pump in autoPilot mode. The secondary goal was to identify possible causes of incorrect timing. During IABP assistance of 60 patients, every four hours a strip was printed with the IABP frequency set to 1:2. Strips were examined for timing discrepancies beyond 40 ms from the dicrotic notch (inflation) and the end of the diastolic phase (deflation). In this way, 320 printed strips were examined. A total of 52 strips (16%) showed incorrect timing. On 24 of these strips, the incorrect timing was called incidental, as it showed on only one or a few beats. The other 28 cases of erroneous timing were called consistent, as more than 50% of the beats on the strip showed incorrect timing. We observed arrhythmia in 69% of all cases of incorrect timing. When timing was correct, arrhythmia was found on 13 (5%) of 268 strips. A poor quality electrocardiograph (ECG) signal showed on 37% of all strips with incorrect timing and 11% of all strips with proper timing. We conclude that inflation and deflation timing of the IABP is not always correct when using the autoPilot mode. The quality of the ECG input signal and the occurrence of arrhythmia appear to be related to erroneous timing. Switching from autoPilot mode to operator mode may not always prevent incorrect timing.

    Educating patients on prenatal genetic screening and carrier testing in a timely and effective manner is faced with barriers including, providers' limited knowledge, and little time available to spend discussing screening and testing during a visit. This paper describes the use of cognitive response interviews (CRI) and usability testing (UT) in the development of an interactive computer assisted instruction (ICAI) program for use by prenatal patients in clinical settings. Lessons learned during the program development process included simplification of content and adaptation of navigational features in response to observations and interviews of a sample of patients representing the intended population. The resulting program functions as a targeted patient education program that maintains the level of medical information needed, as specified by professional practices guidelines, in a patient friendly format. In addition, this ICAI program functions as a research tool that can collect data on program effectiveness. Researchers developing other patient education programs will benefit from the lessons learned during development of this ICAI program by considering rephrasing of content to fit patient understanding, and adding navigational features to help further facilitate effective program use.

    2013-01-01

    Background To identify risk factors for being a “reduced responder” to ranibizumab treatment in a clinical setting in patients with neovascular age-related macular degeneration. Methods This retrospective study included 165 eyes of 165 consecutive patients with choroidal neovascularisation secondary to neovascular, age-related macular degeneration. Eyes were treated with three intravitreal injections of ranibizumab, followed by PRN (pro re nata) dosing thereafter. All patients were reevaluated every four weeks and then followed for six months. Reduced responders were defined as patients with a loss in visual acuity of at least 1 visual acuity line at the last follow-up and/or persistent intraretinal or subretinal fluid or detectable choroidal neovascularisation at the last follow-up, compared to baseline. Results Overall, 58 out of 165 eyes (35.2%) were considered to be reduced responders to treatment at the end of follow-up. The initial CNV size at baseline was correlated with the risk of being a reduced responder at the end of follow-up (p = 0.017). Conclusion We identified the initial lesion size as a predictor for a reduced response to treatment in this study. Patients with a large initial lesion size should be thoroughly informed about the possible poorer response to the intravitreal treatment. PMID:24359591

    A moisturising micro-gel spray for prevention of dryness was compared with commercial products and artificial saliva in vitro and in a clinical setting in patients with cancer. Survival of cultured human gingival epithelial cells was evaluated after treatment with each product for 15 min. A dry test was performed for products giving a 50% survival rate, in which cell survival was measured after drying of cells treated with each product. The survival rates of cells treated with the micro-gel spray and artificial saliva were significantly higher than those of control cells. The micro-gel spray was then evaluated for 1 week in patients with symptoms of dry mouth caused by cancer treatment. There was significant improvement of these symptoms at night and on awakening and of subjective symptoms of decreased salivary volume (P < 0.05). Mean visual analogue scale scores also significantly decreased (P < 0.01). These data suggest that evaluation of moisturising products for dryness prevention can be performed in cultured cells, since products that performed well in vitro also showed good efficacy for symptoms of dry mouth. The micro-gel spray was particularly effective for relieving symptoms of dry mouth in patients with cancer.

    2012-01-01

    A concept found in historical primary sources, and useful in contemporary historiography, is the acronical rising and setting of stars (or planets). Topocentric terms, they provide information about a star's relationship to the Sun and thus its visibility in the sky. Yet there remains ambiguity as to what these two phrases actually mean. "Acronical” is said to have come from the Greek akros ("point,” "summit,” or "extremity") and nux ("night"). While all sources agree that the word is originally Greek, there are alternate etymologies for it. A more serious difficulty with acronical rising and setting is that there are two competing definitions. One I call the Poetical Definition. Acronical rising (or setting) is one of the three Poetical Risings (or Settings) known to classicists. (The other two are cosmical rising/setting, discussed below, and the more familiar helical rising/setting.) The term "poetical" refers to these words use in classical poetry, e. g., that of Columella, Hesiod, Ovid, Pliny the Younger, and Virgil. The Poetical Definition of "acronical” usually is meant in this context. The Poetical Definition of "acronical” is as follows: When a star rises as the Sun sets, it rises acronically. When a star sets as the Sun sets, it sets acronically. In contrast with the Poetical Definition, there also is what I call the Astronomical Definition. The Astronomical Definition is somewhat more likely to appear in astronomical, mathematical, or navigational works. When the Astronomical Definition is recorded in dictionaries, it is often with the protasis "In astronomy, . . . ." The Astronomical Definition of "acronical” is as follows: When a star rises as the Sun sets, it rises acronically. When a star sets as the Sun rises, it sets acronically. I will attempt to sort this all out in my talk.

    accounts and analysis of organizational documents revealed a multidimensional dynamic between the trajectory of secure messaging implementation and its impact on organizational actors and their use of technology, influencing workflow, practices, and the flow of information. In effect, secure messaging was the missing element of complex information ecology and its implementation acted as a catalyst for change. Secure messaging was found to have important consequences for access, communication, patient self-report, and patient/provider relationships. Conclusions Study findings have direct implications for the development and implementation of PHR systems to ensure adequate training and support for health care professionals, alignment with clinical workflow, and features that enable information sharing and communication. Study findings highlight the importance of clinician endorsement and engagement, and the need to further examine both intended and unintended consequences of use. This research provides an integral step toward better understanding the social and organizational context and impact of PHR and secure messaging use in clinical practice settings. PMID:23557596

    Context An increase in enzyme lactate dehydrogenase (LDH) in serum is a negative prognostic factor for survival in cats affected by lymphoma. Measuring LDH at the time of diagnosis has been studied for differentiating neoplastic disease from non-neoplastic disease in dogs. Inflammatory bowel disease (IBD) and alimentary lymphoma are common diseases in cats. Objective The aim of this study was to determine whether elevation of total LDH occurred in cats with alimentary lymphoma and non-neoplastic gastrointestinal disease, such as IBD, and to evaluate whether this enzyme is useful in supporting the differential diagnosis of these specific diseases. Materials and Methods A prospective non-randomized controlled study was carried-out in a real world setting of three Italian private veterinary clinics. Seventy-one client-owned cats with a history of chronic gastrointestinal symptoms were enrolled; 33 cats were histologically diagnosed as having alimentary lymphoma and 38 cats as having IBD. Serum samples of total LDH analysis were measured. Results Gender (P = 0.016) and age (P = 0.046) were found to be significant factors influencing the differentiation of serum total LDH between cats with alimentary lymphoma and those with IBD. Despite low diagnostic accuracy in the overall population (63%), a cut-off value of serum total LDH ranging from 0.85- to 1.04-times the upper reference limit showed good capability (accuracy >80%) of differentiating these two conditions in neutered males and cats younger than 8 years of age (AUC: 0.805, 0.833; sensitivities: 76.9%, 83.3%; specificities: 80.0%, 76.5%; PPV: 76.9%, 55.6%; NPV: 80.0%, 92.9%; respectively). Conclusions Although our study showed that gender and age are significant factors in differentiating serum total LDH between cats with alimentary lymphoma and those with IBD, this test had poor diagnostic accuracy in differentiating between these two conditions in the overall population.

    Recently a discontinuous percolation transition was reported in a new “explosive percolation” problem for irreversible systems [D. Achlioptas, R. M. D’Souza, and J. Spencer, Science 323, 1453 (2009)SCIEAS0036-807510.1126/science.1167782] in striking contrast to ordinary percolation. We consider a representative model which shows that the explosive percolation transition is actually a continuous, second order phase transition though with a uniquely small critical exponent of the percolation cluster size. We describe the unusual scaling properties of this transition and find its critical exponents and dimensions.

    For the calculation of the parasite resistance of an airplane, a knowledge of the resistance of the individual structural and accessory parts is necessary. The most reliable basis for this is given by tests with actual airplane parts at airspeeds which occur in practice. The data given here relate to the landing gear of a Siemanms-Schuckert DI airplane; the landing gear of a 'Luftfahrzeug-Gesellschaft' airplane (type Roland Dlla); landing gear of a 'Flugzeugbau Friedrichshafen' G airplane; a machine gun, and the exhaust manifold of a 269 HP engine.

    .49]), and increased general health quality of life (β = 1.02 [1.00,1.04]) were also independently correlated with viral suppression. Improvements in CD4 lymphocyte count were significantly associated with being on ART and increased over time. Conclusions Initiating BUP/NX in HIV clinical care settings is feasible and correlated with initiation of ART and improved CD4 lymphocyte counts. Longer retention on BPN/NX was not associated with improved prescription of ART, viral suppression, or CD4 lymphocyte counts for the overall sample in which the majority was already prescribed ART at baseline. Among those retained on BUP/NX, HIV treatment outcomes did not worsen and were sustained. Increasing time on BUP/NX, however, was especially important for improving HIV treatment outcomes for those not on ART at baseline, the group at highest risk for clinical deterioration. Retaining subjects on BUP/NX is an important goal for sustaining HIV treatment outcomes for those on ART and improving them for those who are not. Comorbid substance use disorders (especially alcohol), mental health problems, and quality–of-life indicators independently contributed to HIV treatment outcomes among HIV-infected persons with opioid dependence, suggesting the need for multidisciplinary treatment strategies for this population.

    Automatic sets D\\subset{\\bb Z}^m are characterized by having a finite number of decimations. They are equivalently generated by fixed points of certain substitution systems, or by certain finite automata. As examples, two-dimensional versions of the Thue-Morse, Baum-Sweet, Rudin-Shapiro and paperfolding sequences are presented. We give a necessary and sufficient condition for an automatic set D\\subset{\\bb Z}^m to be a Delone set in {\\bb R}^m . The result is then extended to automatic sets that are defined as fixed points of certain substitutions. The morphology of automatic sets is discussed by means of examples.

    Background Antiretroviral regimens with simplified dosing and better safety are needed to maximize the efficiency of antiretroviral delivery in resource-limited settings. We investigated the efficacy and safety of antiretroviral regimens with once-daily compared to twice-daily dosing in diverse areas of the world. Methods and Findings 1,571 HIV-1-infected persons (47% women) from nine countries in four continents were assigned with equal probability to open-label antiretroviral therapy with efavirenz plus lamivudine-zidovudine (EFV+3TC-ZDV), atazanavir plus didanosine-EC plus emtricitabine (ATV+DDI+FTC), or efavirenz plus emtricitabine-tenofovir-disoproxil fumarate (DF) (EFV+FTC-TDF). ATV+DDI+FTC and EFV+FTC-TDF were hypothesized to be non-inferior to EFV+3TC-ZDV if the upper one-sided 95% confidence bound for the hazard ratio (HR) was ≤1.35 when 30% of participants had treatment failure. An independent monitoring board recommended stopping study follow-up prior to accumulation of 472 treatment failures. Comparing EFV+FTC-TDF to EFV+3TC-ZDV, during a median 184 wk of follow-up there were 95 treatment failures (18%) among 526 participants versus 98 failures among 519 participants (19%; HR 0.95, 95% CI 0.72–1.27; p = 0.74). Safety endpoints occurred in 243 (46%) participants assigned to EFV+FTC-TDF versus 313 (60%) assigned to EFV+3TC-ZDV (HR 0.64, CI 0.54–0.76; p<0.001) and there was a significant interaction between sex and regimen safety (HR 0.50, CI 0.39–0.64 for women; HR 0.79, CI 0.62–1.00 for men; p = 0.01). Comparing ATV+DDI+FTC to EFV+3TC-ZDV, during a median follow-up of 81 wk there were 108 failures (21%) among 526 participants assigned to ATV+DDI+FTC and 76 (15%) among 519 participants assigned to EFV+3TC-ZDV (HR 1.51, CI 1.12–2.04; p = 0.007). Conclusion EFV+FTC-TDF had similar high efficacy compared to EFV+3TC-ZDV in this trial population, recruited in diverse multinational settings. Superior safety, especially in HIV-1-infected

  14. Detecting the neuropathic pain component in the clinical setting: a study protocol for validation of screening instruments for the presence of a neuropathic pain component

    PubMed Central

    2014-01-01

    Background The presence of nerve damage plays a key role in the development and prognosis of chronic pain states. Assessment of the presence and severity of a neuropathic pain component (NePC) is key in diagnosing chronic pain patients. Low back pain (LBP) and neck and shoulder pain (NSP) are highly prevalent and clinically important medical and societal problems in which a NePC is frequently present. The more severe the NePC, the worse the course of the pain, its prognosis and the results of treatment. Reliable and standardised diagnosis of the NePC remains difficult to achieve. Standardized and validated screening tools may help to reliably identify the NePC in individual chronic pain patients. The aim of this study is to validate the Dutch language versions of the PainDETECT Questionnaire (PDQ-Dlv) and the ‘Douleur Neuropathique 4 Questions’ (DN4-Dlv) for use in primary and specialist medical care settings to screen for a NePC in patients with chronic pain due to (1) LBP, (2) NSP or (3) known peripheral nerve damage (PND). Methods/design The study design is cross-sectional to assess the validity of the PDQ-Dlv and the DN4-Dlv with 2 weeks follow-up for test-retest reliability and 3 months follow-up for monitoring and prognosis. 438 patients with chronic pain due to (1) LBP, (2) NSP or (3) PND. will be included in this study. Based on the IASP definition of neuropathic pain, two physicians will independently assess whether the patient has a NEPC or not. This result will be compared with the outcome of the PDQ-Dlv & DN4-Dlv, the grading system for neuropathic pain, bed side examination and quantitative sensory testing. This study will further collect data regarding prevalence of NePC, general health status, mental health status, functioning, pain attribution and quality of life. Discussion The rationale for this study is to provide detailed information on the clinimetric quality of the PDQ-Dlv and DN4-Dlv in Dutch speaking countries. Our innovative multi

    Aim The purpose of this study was to assess the prescription of epoetins and consumption of health care resources (in terms of drug treatments) in naïve patients with hematological malignancies in a real-world setting; in particular, we compared the results between reference product and biosimilar products. Methods An observational retrospective study based on administrative and laboratory databases of three local health units was conducted. All adults diagnosed with hematological malignancies and who had received at least one epoetin (either reference product or biosimilars) prescription for the first time between 1 January 2010 and 30 April 2012 (enrollment period) were included. The date of the first prescription of epoetin within the enrollment period was defined as index date (ID). Patients were followed up for 4 weeks after ID (follow-up period) and were investigated for the 1-year period before the ID. The difference between the last hemoglobin (Hb) measurement after ID and the one prior to ID (ΔHb) was evaluated. The drug cost analysis was conducted from the perspective of the Italian National Health System. Results Overall, 69 patients were included in the study; 48 of them received reference epoetin product and 21 received biosimilars as first prescription. Among reference product users, the mean ± standard deviation (SD) age was 62.5±14.7 years; this cohort of patients was slightly significantly younger than the biosimilar users (71.8±11.8 years). The mean ± SD overall Hb level prior to treatment was lower among patients who started with biosimilar products (9.6±1.1 g/dL) compared to those who started with a reference product (10.1±2.1 g/dL). No significant differences in ΔHb were observed between biosimilar and originator groups during the followup period. The mean ± SD cost per patient was €667.98±573.93 and €340.85±235.73 for the reference product and biosimilar users, respectively (p=0.065). Conclusion Our study showed that the use of

    Background Obesity is an important risk factor for atherosclerotic cardiovascular disease (ASCVD). Estimation of visceral adipose tissue is important and several methods are available as its surrogate. Although correlation of epicardial adipose tissue (EAT) with visceral adipose tissue as estimated by magnetic resonance imaging (MRI) and/or CT is excellent, it is costlier and cumbersome. EAT can be accurately measured by two-dimensional (2D) echocardiography. It tends to be higher in patients with acute coronary syndrome than in subjects without coronary artery disease (CAD) and in those with stable angina. It also carries advantage as index of high cardiometabolic risk as it is a direct measure of visceral fat rather than anthropometric measurements. The present study evaluated the relationship of EAT to the presence and severity of CAD in clinical setting. Methods In this prospective, single-center study conducted in the Department of Cardiology, LPS Institute of Cardiology, Kanpur, India, 549 consecutive patients with acute coronary syndrome or chronic stable angina were enrolled. Sensitivity, specificity, and receiver operating characteristic (ROC) curve were estimated to find cut-off value of EAT thickness for diagnosing CAD using coronary angiographic findings as gold standard. Results Patients were diagnosed as CAD group (n = 464, 60.30 ± 8.36 years) and non-CAD group (n = 85, 54.42 ± 11.93 years) after assessing coronary angiograms. The EAT was measured at end-systole from the PLAX views of three cardiac cycles on the free wall of the right ventricle. Lesion was significant if > 50% in left main and > 70% in other coronary arteries. The mean EAT thickness in CAD group was 5.10 ± 1.06 and in non-CAD group was 4.36 ± 1.01 which was significant (P = 0.003). Significant correlation was demonstrated between EAT thickness and presence of CAD (P < 0.003). Higher EAT was associated with severe CAD and presence of mul
