  2. PREDICT : A CASE STUDY.

    SciTech Connect

    Kerscher, W. J. III; Booker, J. M.; Meyer, Mary A.

    2001-01-01

    Delphi Automotive Systems and the Los Alamos National Laboratory worked together to develop PREDICT, a new methodology to characterize the reliability of a new product during its development program. Rather than conducting testing after hardware has been built, and developing statistical confidence bands around the results, this updating approach starts with an early reliability estimate characterized by large uncertainty, and then proceeds to reduce the uncertainty by folding in fresh information in a Bayesian framework. A considerable amount of knowledge is available at the beginning of a program in the form of expert judgment which helps to provide the initial estimate. This estimate is then continually updated as substantial and varied information becomes available during the course of the development program. This paper presents a case study of the application of PREDICT, with the objective of further describing the methodology. PREDICT has been honored with an R&D 100 Award presented by R&D Magazine.

  3. Termination: A Case Study.

    PubMed

    Friedberg, Ahron L

    2015-12-01

    In this article I posit and examine certain criteria and qualities for ending an analysis. The case study describes the end phase of a four-year psychoanalysis in which the patient's decision to move to another area forced the end of his analysis. We continued to explore and work through his core neurotic conflicts that included issues of competitive rivalry, dominance and submission, control, and anxiety about birth and death. A shift in the transference from me as a negative father to me as a supportive but competitive older brother was also examined in the context of ending treatment as well as other aspects of the transference. In addition, we analyzed the meaning of his ending treatment based on an extra-analytic circumstance. In discussing this phase of treatment, the definition and history of the term "termination" and its connotations are reviewed. Various criteria for completing an analysis are examined, and technical observations about this phase of treatment are investigated. It was found that while a significant shift in the transference occurred in this phase of the patient's analysis, conflicts related to the transference were not "resolved" in the classical sense. Terminating treatment was considered as a practical matter in which the patient's autonomy and sense of choice were respected and analyzed.

  4. Dioxin: a case study.

    PubMed

    Bond, G G

    1993-01-01

    The need to notify individuals of a possible health risk from their past exposure to potentially hazardous agents frequently extends beyond workers to include community groups. The issues to consider in community notification are frequently similar to those that are important for worker notification but may include some that are unique. This case study traces the evolution of one company's strategy for communicating with the public about possible dioxin contamination associated with its operations. Early communications tended to emphasize the technical aspects of the issues in the fashion of scientists talking to other scientists. This was interpreted by some to be symptomatic of an arrogant and uncaring attitude. Beginning in the early 1980s, the company's management recognized the need to reach out to a variety of audiences on multiple levels, and shifted to a more comprehensive communications strategy. A similar shift is now occurring throughout the chemical manufacturing industry as top managers realize that, if they expect to continue to operate, they must become more accountable and responsive to the public.

  9. Case studies in working memory: a case for single cases?

    PubMed

    Della Sala, S; Logie, R H; Marchetti, C; Wynn, V

    1991-06-01

    Patterns of cognitive deficit in single neuropsychological cases are common sources of evidence for theories of normal cognition. In particular, the working memory model has benefited from data obtained from a number of contrasting patients, in some cases resulting in modifications of the working memory model. In this paper, patterns of data from short-term memory patients and anarthric patients are compared with patterns of data from normal subjects. The patterns of patient data that were unlike those patterns typically found for groups of normal subjects, could be incorporated within a modified version of the articulatory loop component of the working memory model. However a small number of individual normal subjects also did not show the pattern that is reported on the basis of average performance of groups of normal subjects. This causes some difficulty in interpreting those data from such 'aberrant normal' patterns, and those data from single patients with functional cognitive deficits. The implications of these findings for the interpretation of neuropsychological data are discussed in the context of the working memory model, but with the intention of making a general point pertaining to the development of functional models of cognition. It is argued that single case studies should continue to provide a useful source of evidence, providing that care is exercised in considering the implications of such data for models of normal cognition.

  10. Physiologic amputation: a case study.

    PubMed

    Long, Jeri; Hall, Virginia

    2014-03-01

    Acute limb ischemia is a complication of severe peripheral arterial disease that can be a threatening limb as well as life. Multiple procedures exist today to help revascularize extremities; however, even with the latest technologies, surgical amputation of the limb may still be necessary. Cryoamputation, or physiologic amputation, is a method used to treat patients who are hemodynamically unstable for the operating room and who are in need of urgent amputation owing to arterial ischemia. This procedure is used in the rare instance where not only a persons' limb is threatened, but also their life. This is a case study regarding one patient who presented to the hospital with limb-threatening ischemia who became hemodynamically unstable owing to the rhabdomyolysis associated with the ischemia of his lower extremity. Cryoamputation was used to stabilize the patient and prevent further deterioration, so that he could safely undergo surgical amputation of the limb without an increase in mortality risk. Cryoamputation must be followed by formal surgical amputation when the patient is hemodynamically stabilized. It is not a limb salvaging, procedure but it is a life-saving procedure. This case study demonstrates the usefulness of the procedure and discusses the technique used for cryoamputation.

    2008-01-01

    We report a case of massive associative visual agnosia. In the light of current theories of identification and semantic knowledge organization, a deficit involving both levels of structural description system and visual semantics must be assumed to explain the case. We suggest, in line with a previous case study, an alternative account in the framework of (non abstractive) episodic models of memory.

    2016-01-01

    Background. Polyorchidism, alternatively supernumerary testes (SNT), is a condition where an individual is born with more than two testicles. This congenital anomaly is quite rare and the literature has described various presentations. Questions/Purposes. To our knowledge, this presentation of polyorchidism has yet to be described in the literature. The goal of this case study is to add to the pediatric, general, and urologic surgery's body of knowledge of the subject matter. Case Study. A nine-month-old boy was admitted for an impalpable right testis and phimosis. At the time of surgical exploration, there appeared to be polyorchid testis on the right-hand side, with three masses that potentially appeared to be undescended testes. Discussion. Proponents of a conservative approach argue that infertility is common in patients with polyorchidism and, by preserving a potentially functional SNT, there may be improved spermatogenesis. When performing definitive surgical treatment, meticulous intra-abdominal and intrainguinal exploration must be undertaken. Orchiopexy should be performed to reduce the chances of torsion, malignancy, and infertility. Conclusion. Our case is important to the literature as it is the first known case of polyorchidism with 3 SNT on the right side, located intra-abdominally, and in a patient less than 1 year of age.

  1. Optic Aphasia: A Case Study

    PubMed Central

    Lee, Jae-Hong

    2006-01-01

    Optic aphasia is a rare syndrome in which patients are unable to name visually presented objects but have no difficulty in naming those objects on tactile or verbal presentation. We report a 79-year-old man who exhibited anomic aphasia after a left posterior cerebral artery territory infarction. His naming ability was intact on tactile and verbal semantic presentation. The results of the systematic assessment of visual processing of objects and letters indicated that he had optic aphasia with mixed features of visual associative agnosia. Interestingly, although he had difficulty reading Hanja (an ideogram), he could point to Hanja letters on verbal description of their meaning, suggesting that the processes of recognizing objects and Hanja share a common mechanism.

  4. Pheasant project: a case study

    SciTech Connect

    Halabura, S.P.

    1988-07-01

    Pheasant Project was the name given to a consortium of oil companies that drilled 49 dry holes across central Saskatchewan during late 1968 and early 1969. It was hoped to find commercial amounts of hydrocarbons within reefs of the Middle Devonian Winnipegosis Formation and thus establish central Saskatchewan as a new oil province. Unfortunately, the dry holes discouraged further exploration for deep oil both in the southeast and in the central parts of the province until recent Winnipegosis oil discoveries were made in the tableland area. Why was the Pheasant Project such a disaster. The Pheasant Project was a master-pooling of individual exploration permits held by a variety of companies and arranged by an enterprising landman. The Saskatchewan government agreed to the master-pooling on the condition that the wells be drilled quickly and efficiently. Finding oil became secondary to satisfying the pooling terms. All wells were located within the central part of the Elk point seaway, with the dominant exploration concept being the Keg River-Rainbow Lake model. Contrary to popular belief, the Pheasant Project did find shows of oil, as well as favorable reservoirs. Careful examination of the Pheasant wells reveals fundamental sedimentological sequences and patterns of salt-solution tectonics that are critical to defining oil plays in the Elk Point sequence. Distribution of reservoirs within Winnipegosis reefs, reef morphology, the nature of the Shell Lake-Quill unit, and source rock factors are a few of these.

    SciTech Connect

    Domingos, P.

    1996-12-31

    Two of the most popular approaches to induction are instance-based learning (IBL) and rule generation. Their strengths and weaknesses are largely complementary. IBL methods are able to identify small details in the instance space, but have trouble with attributes that are relevant in some parts of the space but not others. Conversely, rule induction methods may overlook small exception regions, but are able to select different attributes in different parts of the instance space. The two methods have been unified in the RISE algorithm. RISE views instances as maximally specific rules, forms more general rules by gradually clustering instances of the same class, and classifies a test example by letting the nearest rule win. This approach potentially combines the advantages of rule induction and IBL, and has indeed been observed to be more accurate than each on a large number of bench-mark datasets. However, it is important to determine if this performance is indeed due to the hypothesized advantages, and to define the situations in which RISE`s bias will and will not be preferable to those of the individual approaches. This abstract reports experiments to this end in artificial domains.

  14. Nanomaterial Case Study: A Comparison of Multiwalled ...

    EPA Pesticide Factsheets

    The draft document is intended to be used as part of a process to identify what is known and, more importantly, what is not yet known that could be of value in assessing the broad implications of specific nanomaterials. Like previous case studies (see History/ Chronology below), this draft case study on multiwalled carbon nanotubes (MWCNTs) is based on the comprehensive environmental assessment (CEA) approach, which consists of both a framework and a process. Unlike previous case studies this case study incorporates information about a traditional (i.e., “non-nano-enabled”) product, against which the MWCNT flame-retardant coating applied to upholstery textiles (i.e., the “nano-enabled” product) can be compared. The comparative element serves dual-purposes: 1) to provide a more robust database that facilitates identification of data gaps related to the nano-enabled product and 2) to provide a context for identifying key factors and data gaps for future efforts to evaluate risk-related trade-offs between a nano-enabled and non-nano-enabled product. This draft case study does not represent a completed or even a preliminary assessment of MWCNTs; rather, it uses the CEA framework to structure information from available literature and other resources (e.g., government reports) on the product life cycle, fate and transport processes in various environmental media, exposure-dose characterization, and impacts in human, ecological, and environmental receptors.

    Necrotizing fasciitis represents a group of highly lethal infections characterized by rapidly progressing inflammation and necrosis. The aim of the study was to analyze the clinical profile, microbial flora, and predisposing risk factors in patients with necrotizing fasciitis. Lastly, we aimed to formulate a protocol for management of necrotizing fasciitis. Forty-eight cases of necrotizing fasciitis patients who reported to our hospital between April 2007 and September 2009 were included in the study. The commonest predisposing factors were age greater than 50 years (58 % cases) and diabetes mellitus (52 % cases). The commonest site involved was extremity (70.8 %). Majority of infections were polymicrobial (87.5 %). Repeated aggressive debridement was the commonest surgical procedure performed. Early and aggressive surgical debridement, often in multiple sittings, supplemented by appropriate antibiotics and supportive therapy, forms the key to a successful outcome in necrotizing fasciitis.

    Background Publicly funded clinical trials require a substantial commitment of time and money. To ensure that sufficient numbers of patients are recruited it is essential that they address important questions in a rigorous manner and are managed well, adopting effective marketing strategies. Methods Using methods of analysis drawn from management studies, this paper presents a structured assessment framework or reference model, derived from a case analysis of the MRC's CRASH trial, of 12 factors that may affect the success of the marketing and sales activities associated with clinical trials. Results The case study demonstrates that trials need various categories of people to buy in – hence, to be successful, trialists must embrace marketing strategies to some extent. Conclusion The performance of future clinical trials could be enhanced if trialists routinely considered these factors. PMID:18028537

  4. Nanomaterial Case Study: A Comparison of Multiwalled ...

    EPA Pesticide Factsheets

    This Independent Peer Review Draft document presents a case study of multiwalled carbon nanotubes (MWCNTs); it focuses on the specific example of MWCNTs as used in flame-retardant coatings applied to upholstery textiles. This case study is organized around the comprehensive environmental assessment (CEA) framework, which structures available information pertaining to the product life cycle, environmental transport and fate, exposure-dose in receptors (i.e., humans, ecological populations, and the environment), and potential impacts in these receptors. The document does not draw conclusions about potential risks, or present an exhaustive review of the literature. Rather, it was used in an independent peer review to provide feedback on revisions that EPA made to the external review draft of the document based on public comments and the CEA process to identify research gaps for MWCNTs. This document seeks to identify what is known and unknown related to assessing the health and environmental implications of a nanomaterial; in this case multiwalled carbon nanotubes (MWCNTs) used in flame-retardant coatings applied to textiles.

    2011-01-01

    Pain is a widespread issue in the United States. Nine of 10 Americans regularly suffer from pain, and nearly every person will experience low back pain at one point in their lives. Undertreated or unrelieved pain costs more than $60 billion a year from decreased productivity, lost income, and medical expenses. The ability to diagnose and provide appropriate medical treatment is imperative. This case study examines a 23-year-old Active Duty woman who is preparing to be involuntarily released from military duty for an easily correctable medical condition. She has complained of chronic low back pain that radiates into her hip and down her leg since experiencing a work-related injury. She has been seen by numerous providers for the previous 11 months before being referred to the chronic pain clinic. Upon the first appointment to the chronic pain clinic, she has been diagnosed with sacroiliac joint dysfunction. This case study will demonstrate the importance of a quality lower back pain assessment.

    PubMed

    Dinnsen, Daniel A; Gierut, Judith A; Morrisette, Michele L; Rose, Darcy E

    2014-01-01

    This paper focuses on three seemingly unrelated error patterns in the sound system of a child with a phonological delay, Child 218 (male, age 4 years 6 months) and ascribes those error patterns to a larger conspiracy to eliminate fricatives from the phonetic inventory. Employing Optimality Theory for its advantages in characterizing conspiracies, our analysis offers a unified account of the observed repairs. The contextual restrictions on those repairs are, moreover, attributed to early developmental prominence effects, which are independently manifested in another error pattern involving rhotic consonants. Comparisons are made with a published case study involving a different implementation of the same conspiracy, the intent being to disambiguate the force behind certain error patterns. The clinical implications of the account are also considered.

  11. Microgravity isolation system design: A case study

    Hampton, R. D.; Knospe, C. R.; Allaire, P. E.; Grodsinsky, C. M.

    1994-01-01

    Many acceleration-sensitive, microgravity science experiments will require active vibration isolation from manned orbiters on which they will be mounted. The isolation problem, especially in the case of a tethered payload, is a complex three-dimensional one that is best suited to modern-control design methods. In this paper, extended H(sub 2) synthesis is used to design an active isolator (i.e., controller) for a realistic single-input-multiple-output (SIMO) microgravity vibration isolation problem. Complex mu-analysis methods are used to analyze the isolation system with respect to sensor, actuator, and umbilical uncertainties. The paper fully discusses the design process employed and the insights gained. This design case study provides a practical approach for isolation problems of greater complexity. Issues addressed include a physically intuitive state-space description of the system, disturbance and noise filters, filters for frequency weighting, and uncertainty models. The controlled system satisfies all the performance specifications and is robust with respect to model uncertainties.

  12. Nocturnal bruxism and hypnotherapy: a case study.

    Dowd, E Thomas

    2013-01-01

    This article describes a case study of a hypnotherapeutic treatment of nocturnal bruxism. The author saw the client for a total of 7 sessions. Hypnotherapy was interspersed with an exploration of tacit and initially denied hostility in the client's life as well as aspects of a somewhat difficult childhood. At the end, the bruxism had disappeared. Follow-up 1 year later indicated that the bruxism had not returned, and the client had become more assertive in her relations with others and had more exploratory activities in her life directions. The latter had not been dealt with in therapy. Thus, there appeared to be a "ripple effect" of successful therapy from one part of her life into its other aspects.

    The scheduling in job shop is important for efficient utilization of machines in the manufacturing industry. There are number of algorithms available for scheduling of jobs which depend on machines tools, indirect consumables and jobs which are to be processed. In this paper a case study is presented for scheduling of jobs when parts are treated on available machines. Through time and motion study setup time and operation time are measured as total processing time for variety of products having different manufacturing processes. Based on due dates different level of priority are assigned to the jobs and the jobs are scheduled on the basis of priority. In view of the measured processing time, the times for processing of some new jobs are estimated and for efficient utilization of the machines available an algorithm is proposed and validated.

    2000-01-01

    This article describes a case of Shared Psychotic Disorder in a married couple. Because only one of the partners of the pair (the inducer) was alive, at the time of the research, the other partner (the recipient) is presented by using a "psychological autopsy" based both on 19 tape recordings containing her delusional recollections and on a history provided by the husband. The content of their delusion, shaped by a fantasy theme of contemporary Western culture, is unique among cases of Shared Psychotic Disorder published in the last 30 years. The discussion following the case presentation draws attention to the potential risk of this type of case leading to a homicide-suicide pact. Additionally, comments are made about both the pathogenesis, with emphasis on psychodynamic hypothesis, and a consideration of the prognosis, which seems modulated by cultural factors.

    1988-01-01

    A case study of the impact of Ada on a Command and Control project completed at the Jet Propulsion Laboratory (JPL) is given. The data for this study was collected as part of a general survey of software costs and productivity at JPL and other NASA sites. The task analyzed is a successful example of the use of rapid prototyping as applied to command and control for the U.S. Air Force and provides the U.S. Air Force Military Airlift Command with the ability to track aircraft, air crews and payloads worldwide. The task consists of a replicated database at several globally distributed sites. The local databases at each site can be updated within seconds after changes are entered at any one site. The system must be able to handle up to 400,000 activities per day. There are currently seven sites, each with a local area network of computers and a variety of user displays; the local area networks are tied together into a single wide area network. Using data obtained for eight modules, totaling approximately 500,000 source lines of code, researchers analyze the differences in productivities between subtasks. Factors considered are percentage of Ada used in coding, years of programmer experience, and the use of Ada tools and modern programming practices. The principle findings are the following. Productivity is very sensitive to programmer experience. The use of Ada software tools and the use of modern programming practices are important; without such use Ada is just a large complex language which can cause productivity to decrease. The impact of Ada on development effort phases is consistent with earlier reports at the project level but not at the module level.

  3. Case study for a vaccine against leishmaniasis.

    Alvar, Jorge; Croft, Simon L; Kaye, Paul; Khamesipour, Ali; Sundar, Shyam; Reed, Steven G

    2013-04-18

    Leishmaniasis in many ways offers a unique vaccine case study. Two reasons for this are that leishmaniasis is a disease complex caused by several different species of parasite that are highly related, thus raising the possibility of developing a single vaccine to protect against multiple diseases. Another reason is the demonstration that a leishmaniasis vaccine may be used therapeutically as well as prophylactically. Although there is no registered human leishmaniasis vaccine today, immunization approaches using live or killed organisms, as well as defined vaccine candidates, have demonstrated at least some degree of efficacy in humans to prevent and to treat some forms of leishmaniasis, and there is a vigorous pipeline of candidates in development. Current approaches include using individual or combined antigens of the parasite or of salivary gland extract of the parasites' insect vector, administered with or without formulation in adjuvant. Animal data obtained with several vaccine candidates are promising and some have been or will be entered into clinical testing in the near future. There is sufficient scientific and epidemiological justification to continue to invest in the development of vaccines against leishmaniasis.

    PubMed

    Jung, Sharon

    2007-08-01

    Migraine headaches are common and among the most disabling nonfatal conditions of humankind. They are frequently misdiagnosed, which may lead to undertreatment. Patients often self-diagnose and self-medicate, resulting in inadequate treatment. Consequently, patients may take additional doses, trying to gain relief with inappropriate medications. Rebound can ensue. With adequate treatment, a patient's condition and quality of life may improve considerably. Patient education is extremely important to help patients identify appropriate self-care measures, such as identification of triggering events and coping with the chronic nature of their condition. This case study presents a patient who began experiencing migraines following a neck injury. His headaches became more frequent, and ergotamine and caffeine (Cafergot) suppositories were prescribed. When he presented, he was experiencing daily headaches and using daily ergotamine and caffeine suppositories. He was using the emergency department (ED) frequently because of severe headaches. Cervical spasm was recognized as his trigger, and the ergotamine and caffeine suppositories were discontinued. After 3 days of severe headaches, his rebound ceased. He reverted back to episodic migraines, which he treated with zolmitriptan (Zomig) nasal spray, which was effective. His cervical spasm was treated with botulinum toxin type A (Botox), with excellent results. He has maintained reasonable headache control for 2 years.

    Schober, Michael F; Spiro, Neta

    2014-01-01

    To what extent and in what arenas do collaborating musicians need to understand what they are doing in the same way? Two experienced jazz musicians who had never previously played together played three improvisations on a jazz standard ("It Could Happen to You") on either side of a visual barrier. They were then immediately interviewed separately about the performances, their musical intentions, and their judgments of their partner's musical intentions, both from memory and prompted with the audiorecordings of the performances. Statements from both (audiorecorded) interviews as well as statements from an expert listener were extracted and anonymized. Two months later, the performers listened to the recordings and rated the extent to which they endorsed each statement. Performers endorsed statements they themselves had generated more often than statements by their performing partner and the expert listener; their overall level of agreement with each other was greater than chance but moderate to low, with disagreements about the quality of one of the performances and about who was responsible for it. The quality of the performances combined with the disparities in agreement suggest that, at least in this case study, fully shared understanding of what happened is not essential for successful improvisation. The fact that the performers endorsed an expert listener's statements more than their partner's argues against a simple notion that performers' interpretations are always privileged relative to an outsider's.

    2006-12-01

    Software reuse has several obvious advantages. By taking advantage of the experience and skill of colleagues one not only saves time, money and resources, but can also jump start a project that might otherwise have floundered from the start, or not even have been possible. One of the least talked about advantages of software reuse is it helps keep the work interesting for the developers. Reuse prevents developers from spending time and energy writing software solutions to problems that have already been solved, and frees them to concentrate on solving new problems, developing new components, and doing things that have never been done before. At the National Snow and Ice Data Center we are fortunate our user community has some unique needs that aren't met by mainstream solutions. Consequently we look for reuse opportunities wherever possible so we can focus on the tasks that add value for our user community. This poster offers a case study of one thread through a decade of reuse at NSIDC that has involved eight different development efforts to date.

    2009-04-01

    Floods are among the most frequent and costly natural disasters in terms of human hardship and economic loss. Depending on topography, soil condition, ground cover, human settlements and other factors, flood can produce catastrophic impacts both in terms of damages and modification of the landscape. The Salerno province experienced numerous flooding events after heavy thunderstorm, that triggered intense landslides (debris-mudflow), inundations, denudation, shore line progradation, etc. Recent study (Porfido et al. 2009) show that in this area more than 100 flooding events occurred since 1500. Among these four events have been estimate in the maximum severity class. Research into the historical flooding highlights the case of the event of 11 November 1773 as one of the major flooding occurred in Cava de' Tirreni, Campanian region, Southern Italy. About 400 - 450 people died; severe damage to the buildings were registered in a wide area of the Salerno province; several mud flows invested large areas of coastal territory which caused progradation phenomena of the shoreline of several hundreds of meters.

    2013-05-01

    This case study compares two different clinical outcomes for a patient with a long-standing psychotic disorder prescribed clozapine on two occasions. During the first trial, clozapine was used at a higher dose for this patient (350-450mg/day) and included clinically significant sialorrhea, pneumonia, and pneumonia-like illnesses requiring immediate medical intervention including hospitalization. There were also patient complaints of fatigue, cough, choking, and constipation leading to poor adherence. Clozapine was discontinued when the patient withdrew his consent due to side effects, despite his awareness of its benefits, including reduction of command hallucinations and irritability. The second clozapine trial was associated with lower daily doses and therapeutic serum blood levels. The patient was actively participating in and adhering to the medication plan. A very narrow window of clozapine dose was exceeded for two days and the patient complained of hypersalivation, cough, and lethargy. He was subsequently hospitalized for a two week period to treat aspiration pneumonia. This hospitalization helped establish the ideal daily dose of clozapine for this patient and also brought the relationship between aspiration pneumonia and clozapine to the attention of the psychiatrist and medical specialist. Once the appropriate dosage for this patient was established, his psychotic and affective symptoms were controlled, he was not hampered by adverse side effects, and he started to actively participate in social and recreational activities and plans that culminated in discharge from a state psychiatric facility to a supportive community residence. It is our hope that the lessons we have learned from our shared experience with this patient will be of benefit to other clinicians and patients.

  15. Quality improvement initiatives in a case management service: case study.

    PubMed

    Davies, Deborah J

    2015-01-01

    This article explores the importance of quality practices in underpinning the person-centred approach at a Community Options Program (COP) case management service in northern NSW. The NSW community care sector does not have a statutory excellence body to identify, promote and support improved practices and quality and safety across community services, and therefore the COP provider decided to establish a dedicated role to focus on the quality improvement of its service. The subsequent quality improvement initiatives have included mapping the clients' journey through the service, identifying areas to standardise practice, and creating service pathways. The clients' journey was used as the framework to identify where standardised practice was required, and a robust process was implemented to develop over 25 good practice guidelines and tools that addressed the variations in practice and enabled the service pathways to be developed. Prior to trialling the guidelines and tools, staff received education sessions on the anticipated changes to practice, and the practicality and applicability of the guidelines were evaluated at the end of the trials. This information was reviewed and the guidelines were amended accordingly before being rolled out. The guidelines have been in use for over 12 months and have provided the benchmark against which to audit practice, and have resulted in key performance improvements such as an increase in client review rates and a rise in the feedback response rate from clients, with a noticeable shift in the comments about the brokered support worker to acknowledging the role of their case manager. Formalising informal supports for those clients that lived alone also increased, which means these people are less reliant on services and there is a reduced risk of social isolation.

    Background Erythroderma is a rare skin disorder that may be caused by a variety of underlying dermatoses, infections, systemic diseases and drugs. Methods We reviewed the clinical, laboratory and biopsy material of 97 patients diagnosed with erythroderma who were treated in our department over a 6-year period (1996 through 2002). Results The male-female ratio was 1.85:1. The mean age at diagnosis was 46.2 years. The most common causative factors were dermatoses (59.7%), followed by drug reactions (21.6%), malignancies (11.3%) and idiopathic causes (7.2%). Carbamazepine was the most common drug (57.1%). The best clinicopathologic correlation was found in cutaneous T-cell lymphoma and pityriasis rubra pilaris related erythroderma. Apart from scaling and erythema that were present in all patients, pruritus was the most common finding (97.5%), followed by fever (33.6%), lymphadenopathy (21.3%), edema (14.4%) and hyperkeratosis (7.2%). Conclusion This study outlines that underlying etiologic factors of erythroderma may show geographic variations. Our series had a high percentage of erythroderma secondary to preexisting dermatoses and a low percentage of idiopathic cases. There was no HIV-infected patient among our series based on multiple serum antibody tests. The clinical features of erythroderma were identical, irrespective of the etiology. The onset of the disease was usually insidious except in drug-induced erythroderma, where it was acute. The group associated with the best prognosis was that related to drugs. PMID:15882451

    The Isakower phenomenon is a situation in which an individual typically experiences perceptions of enlargement or thickening, altered states of consciousness, sensations of floating, and impressions of the emergence and disappearance of an oral mass. This paper defines the phenomenon, reviews the literature, and describes a case in which a patient experienced it. The patient manifested the phenomenon symptomatically in the aftermath of a toxic state, and the elements were analysed for several years. There was support for Isakower's original thesis that the regressive states serve to defend against threatening incestuous fantasies. However, the Isakower phenomenon in this patient was the result of a multiplicity of determinants, largely defensive, involving many developmental levels.

    Pityriasis amiantacea was first described in 1832. The disease may be secondary to any skin condition that primarily affects the scalp, including seborrheic dermatitis. Its pathogenesis remains uncertain. We aim to analyze the epidemiological and clinical profiles of patients with pityriasis amiantacea to better understand treatment responses. We identified seven cases of pityriasis amiantacea and a female predominance in a sample of 63 pediatric patients with seborrheic dermatitis followed for an average of 20.4 months. We reported a mean age of 5.9 years. Five patients were female, with a mean age of 9 years. All patients were successfully treated with topic ketoconazole. PMID:27828657

    Anejaculation is an uncommon clinical entity that may result from a variety of causes, both organic and psychological. Psychogenic anejaculation is influenced by relationship, behavioral, and psychological factors. We present a clinical case of situational anejaculation, which was managed with a combination of techniques that addressed these factors including changes in masturbatory technique, improved marital communication and quality, and reduction of anxiety using cognitive behavioral techniques. It is suggested that the standard techniques of sex therapy be modified and tailored to manage the specific problems of the individual patient. PMID:25035564

    Moreno Arroyo, M Carmen; Puig Llobet, Montserrat; Cuervo Lavado, Luis

    2012-01-01

    Fulminant hepatic failure (FHF), also known as fulminant hepatitis, is a rare and extremely serious condition with a high mortality rate. Its rapid evolution and complexity in managing the treatment, creates the need to provide some immediate care by a team that specialises in intensive care. This acute decompensation is usually associated with other disorders, such as coagulopathy and hepatic encephalopathy, being responsible for major complications that can lead to organ failure. In our region the most common origin is unknown, followed by acute infection with hepatitis B. The treatment of this syndrome is based on the general measures applicable to any critically ill patient: treat the cause and early detection of extrahepatic complications, urgent liver transplantation being one of the alternatives with a better prognosis. This article presents a case report describing the monitoring of an Irish woman of 20 years who was transferred from a hospital in Ibiza to a hospital in Barcelona, with a suspected diagnosis of FHF. Following the conceptual model of Virginia Henderson, the collaborative problems and nursing diagnoses are described, presenting a care plan according to NANDA (North American Nursing Association), NIC (Nursing Intervention Classification), NOC (Nursing Outcomes Classification). This case helps to establish an individualised care plan that provides guidance to nurse professionals in critical patient care by increasing the knowledge of FHF.

    Sturge-Weber syndrome (SWS) is a rare, sporadic, progressive, congenital syndrome. In its complete trisymptomatic form, SWS is physically characterized by port-wine stains over the trigeminal area, leptomeningeal angiomas usually over the parieto-occipital region, and eye abnormalities. Clinical manifestation for infants with SWS depends on the affected organs, but can include seizures, mental retardation, and glaucoma. This article begins with a case presentation of an infant with SWS and then presents the etiology, embryology, pathophysiology, clinical presentation, management, and prognosis of SWS.

    Pilonidal sinus (PNS) occurs in the cleavage between the buttocks (natal cleft) and can cause discomfort, embarrassment and absence from work for thousands of young people (mostly men) annually. The incidence of the disease is calculated to be 26 per 100,000 people. It occurs 2.2 times more often in men than in women. Age at presentation is 21 years for men and 19 years for women this case report describes a 22-year-old man with pilonidal sinus who was treated with ksharasutra. PMID:21170212

  6. Benzocaine-induced methaemoglobinaemia: a case study.

    PubMed

    Bittmann, Stefan; Krüger, Carsten

    Benzocaine is a widely used topical anaesthetic and has been reported to cause toxic methaemoglobinaemia in otherwise healthy individuals with no predisposing risk factors. This article reports on a rare case of benzocaine-induced methaemoglobinaemia following adenotonsillectomy in a 5-year-old girl. Topical benzocaine was applied orally for the relief of postoperative wound pain on the eighth postoperative day. Two hours after application, generalized cyanosis, mild dyspnoea and some degree of agitation developed. The methaemoglobin level was 38.5%. Treatment with methylene blue was initiated immediately. Symptoms completely disappeared 4 hours after initiation of methylene blue therapy. The further course was uneventful. Therefore, all health professionals should be aware that topical anaesthetics after surgery can induce methaemoglobinaemia in children, even after a prolonged interval, and especially when applied on wound surfaces.

  7. Cryptosporidiosis susceptibility and risk: a case study.

    PubMed

    Makri, Anna; Modarres, Reza; Parkin, Rebecca

    2004-02-01

    Regional estimates of cryptosporidiosis risks from drinking water exposure were developed and validated, accounting for AIDS status and age. We constructed a model with probability distributions and point estimates representing Cryptosporidium in tap water, tap water consumed per day (exposure characterization); dose response, illness given infection, prolonged illness given illness; and three conditional probabilities describing the likelihood of case detection by active surveillance (health effects characterization). The model predictions were combined with population data to derive expected case numbers and incidence rates per 100,000 population, by age and AIDS status, borough specific and for New York City overall in 2000 (risk characterization). They were compared with same-year surveillance data to evaluate predictive ability, assumed to represent true incidence of waterborne cryptosporidiosis. The predicted mean risks, similar to previously published estimates for this region, overpredicted observed incidence-most extensively when accounting for AIDS status. The results suggest that overprediction may be due to conservative parameters applied to both non-AIDS and AIDS populations, and that biological differences for children need to be incorporated. Interpretations are limited by the unknown accuracy of available surveillance data, in addition to variability and uncertainty of model predictions. The model appears sensitive to geographical differences in AIDS prevalence. The use of surveillance data for validation and model parameters pertinent to susceptibility are discussed.

  8. Congenital amusia in childhood: a case study.

    PubMed

    Lebrun, Marie-Andrée; Moreau, Patricia; McNally-Gagnon, Andréane; Mignault Goulet, Geneviève; Peretz, Isabelle

    2012-06-01

    Here we describe the first documented case of congenital amusia in childhood. AS is a 10-year-old girl who was referred to us by her choir director for persisting difficulties in singing. We tested her with the child version of the Montreal Battery for the Evaluation of Amusia (MBEA) which confirmed AS's severe problems with melodic and rhythmic discrimination and memory for melodies. The disorder appears to be limited to music since her audiometry as well as her intellectual and language skills are normal. Furthermore, the musical disorder is associated to a severe deficit in detecting small pitch changes. The electrical brain responses point to an anomaly in the early stages of auditory processing, such as reflected by an abnormal mismatch negativity (MMN) response to small pitch changes. In singing, AS makes more pitch than time errors. Thus, despite frequent and regular musical practice, AS's profile is similar to the adult form of congenital amusia.

  9. Methylbromide intoxication: a clinical case study.

    PubMed

    Breeman, Wim

    2009-01-01

    The port of Rotterdam, The Netherlands, is the world's largest container port. In 2006, one of these containers caused a chemical incident. Methylbromide is used in some countries as a pesticide for the fumigation of maritime containers. Because of an insufficiently performed detoxification, this insecticide intoxicated several employees and some of the ambulance crew and Mobile Medical Team (MMT). The victims displayed symptoms of sore throat, irritated eyes, and hypersalivation. One of the victims suffered from multiple epileptic seizures. Two victims were admitted to the intensive care unit for respiratory support. Three other employees showed milder symptoms and received supportive care but were not admitted to the hospital. This complicated case shows that the safety of the ambulance crew and MMT must be guaranteed. It also demonstrates that healthcare providers cannot always oversee the accident scene and that there are some pitfalls that are almost impossible to prevent.

    Estus, Janice L.; Fardo, David W.

    2013-01-01

    Genome-wide association studies (GWAS) explore the relationship between genome variability and disease susceptibility with either population- or family-based data. Here, we have evaluated the utility of combining population- and family-based statistical association tests and have proposed a method for reducing the burden of multiple testing. Unrelated singleton and parent-offspring trio cases and controls from the Genetics of Kidneys in Diabetes (GoKinD) study were analyzed for genetic association with diabetic nephropathy (DN) in type 1 diabetics (T1D). The Cochran-Armitage test for trend and the family-based association test were employed using either unrelated cases and controls or trios, respectively. In addition to combining single nucleotide polymorphism (SNP) p-values across these tests via Fisher's method, we employed a novel screening approach to rank SNPs based on conditional power for more efficient testing. Using either the population-based or family-based subset alone predictably limited resolution to detect DN SNPs. For 384,197 SNPs passing quality control (QC), none achieved strict genome-wide significance (1.4 × 10−7) using 1171 singletons (577/594 cases/controls) or 1738 pooled singletons and offspring probands (841/897). Similarly, none of the 352,004 SNPs passing QC in 567 family trios (264/303 case/control proband trios) reached genome-wide significance. Testing the top 10 SNPs ranked using aggregated conditional power resulted in two SNPs reaching genome-wide significance, rs11645147 on chromosome 16 (p = 1.74 × 10−4 < 0.05/10 = 0.005) and rs7866522 on chromosome 9 (p = 0.0033). Efficient usage of mixed designs incorporating both unrelated and family-based data may help to uncover associations otherwise difficult to detect in the presence of massive multiple testing corrections. Capitalizing on the strengths of both types while using screening approaches may be useful especially in light of large-scale, next-generation sequencing and rare

    A joint study has been conducted by NASA and Army installations collocated in a dense forest in southwestern Mississippi in order to determine the technical and economic feasibility of using wood waste as a renewable energy source. The study has shown that, with proper forest management, the timber on government lands could eventually support the total energy requirements of 832 billion Btu/yr. Analysis of the current conversion technologies indicates that the direct combustion spreader stoker approach is the best demonstrated technology for this specific application. The economics of the individual powerplants reveal them as attractive alternatives to fossil fueled plants. Environmental aspects are also discussed.

    Cerebral venous thrombosis (CVT) is a rare origin of stroke, the clinical presentation and etiologies vary. The prognosis is shown to be better than arterial thrombosis. Magnetic Resonance Imaging (MRI) and MR Venograpgy (MRV) are currently important tools for the diagnosis. We studied 30 cases of CVT diagnosed in the department of neurology at the University Hospital of Fez (Morocco). Patients diagnosed with CVT signs between January 2003 and October 2007 were included in the study. Cerebral CT-scan was performed in 27 cases (90%) while the MRI examination was done in 18 patients (67%); and most patients (90%) received anticoagulant therapy. The mean age of our patients was of 29 years (age range between 18 days and 65 years). A female predominance was observed (70%). The clinical presentation of patients was dominated by: headache in 24 cases (80%), motor and sensory disability in 15 cases (50%), seizures in 10 cases (33%), consciousness disorder in 10 cases (33%). CVT was associated to post-partum in 10 cases (33%), infectious origin in 8 cases (26%), Behçet disease in 2 cases (7%), pulmonary carcinoma in 1 case, thrombocytemia in 1 case and idiopathic in 7 cases (23%). The evolution was good in 20 cases (67%), minor squelaes were observed in 6 patients (20%), while major squelaes were observed in 2 cases. Two cases of death were registered. The CVT is a pathology of good prognosis once the diagnosis is promptly established and early heparin treatment initiated. PMID:25317229

    Kiss, G.; Kinkead, J.; Raman, M.

    1995-03-01

    In 1992, Kiss Cathcart Anders Architects performed a study for NREL on Building-Integrated Photovoltaics (BIPV) issues as seen from the perspective of the building community. In general, the purpose of the study was to list major issues and potential applications; by it`s nature it asked more questions than it answered. This second phase study was to produce quantitative data on the performance of specific BIPV systems. Only roof systems are evaluated. The energy performance, construction cost and simple payback for five different BIPV roof options are evaluated in six different locations: Oakland, New York, Miami, Phoenix, Chicago, and Cincinnati. The roof options evaluated include the following: single-glazed PV roof using glass-substrate PVs; double-glazed PV roof with insulating PV modules; ballasted roof-mounted system; sawtooth light monitor roof with indirect north daylighting; sawtooth roof with north light and active heat recovery.

    2009-09-01

    A single subject prospective study of the relationship between air travel and lymphedema is reported. This proof of concept study was aimed at assessing the feasibility of using self-measured, inter-limb impedance ratios as a quantitative measure of lymphedema immediately prior to and following flying. The participant, a breast cancer survivor with lymphedema, measured whole arm impedance prior to and following air travel on 20 occasions, varying in duration of between 1 and 9 h, over a 12-month period. Although the inter-arm impedance ratio fluctuated over this time, it generally increased and worsened following flying. Impedance measurements were easily performed by the participant and could be obtained as close to the start and cessation of flying as is practicably possible. These data, when associated with self-assessment of lymphedema-related symptoms, could provide a comprehensive evidence base for an assessment of the risks associated with air travel and the provision of appropriate advice to prospective travelers. Further large-scale studies are recommended.

  15. Evolution of Research - A Case Study

    Skews, Beric

    Many complex and fascinating flow features occur when a shock wave impinges on or around a surface. Understanding of these is important in view of the increasing application in a variety of fields, such as medicine and material modification, besides the more conventional fields of blast loading of structures and supersonic aerodynamics. This paper deals with some of the developments of research in the field of shock wave studies at the Flow Research Unit of the University of the Witwatersrand. It covers both successful and unsuccessful investigations and suggests those that still need further work.

    1991-01-01

    Alternatives are reviewed for accessing distributed heterogeneous databases and a recommended solution is proposed. The current study is limited to the Automated Information Systems Center at the Naval Sea Combat Systems Engineering Station at Norfolk, VA. This center maintains two databases located on Digital Equipment Corporation's VAX computers running under the VMS operating system. The first data base, ICMS, resides on a VAX11/780 and has been implemented using VAX DBMS, a CODASYL based system. The second database, CSA, resides on a VAX 6460 and has been implemented using the ORACLE relational database management system (RDBMS). Both databases are used for configuration management within the U.S. Navy. Different customer bases are supported by each database. ICMS tracks U.S. Navy ships and major systems (anti-sub, sonar, etc.). Even though the major systems on ships and submarines have totally different functions, some of the equipment within the major systems are common to both ships and submarines.

  5. A Simple Case Study of a Grid Performance System

    NASA Technical Reports Server (NTRS)

    Aydt, Ruth; Gunter, Dan; Quesnel, Darcy; Smith, Warren; Taylor, Valerie; Biegel, Bryan (Technical Monitor)

    2001-01-01

    This document presents a simple case study of a Grid performance system based on the Grid Monitoring Architecture (GMA) being developed by the Grid Forum Performance Working Group. It describes how the various system components would interact for a very basic monitoring scenario, and is intended to introduce people to the terminology and concepts presented in greater detail in other Working Group documents. We believe that by focusing on the simple case first, working group members can familiarize themselves with terminology and concepts, and productively join in the ongoing discussions of the group. In addition, prototype implementations of this basic scenario can be built to explore the feasibility of the proposed architecture and to expose possible shortcomings. Once the simple case is understood and agreed upon, complexities can be added incrementally as warranted by cases not addressed in the most basic implementation described here. Following the basic performance monitoring scenario discussion, unresolved issues are introduced for future discussion.

  6. Cirrus cloud iridescence: a rare case study.

    PubMed

    Sassen, Kenneth

    2003-01-20

    On the evening of 25 November 1998, a cirrus cloud revealing the pastel colors of the iridescence phenomenon was photographed and studied by a polarization lidar system at the University of Utah Facility for Atmospheric Remote Sensing (FARS). The diffraction of sunlight falling on relatively minute cloud particles, which display spatial gradients in size, is the cause of iridescence. According to the 14-year study of midlatitude cirrus clouds at FARS, cirrus rarely produce even poor iridescent patches, making this particularly long-lived and vivid occurrence unique. In this unusually high (13.2-14.4-km) and cold (-69.7 degrees to -75.5 degrees) tropopause-topped cirrus cloud, iridescence was noted from approximately 6.0 degrees to approximately 13.5 degrees from the Sun. On the basis of simple diffraction theory, this indicates the presence of particles of 2.5-5.5-microm effective diameter. The linear depolarization ratios of delta = 0.5 measured by the lidar verify that the cloud particles were nonspherical ice crystals. The demonstration that ice clouds can generate iridescence has led to the conclusion that iridescence is rarely seen in midlatitude cirrus clouds because populations of such small particles do not exist for long in the presence of the relatively high water-vapor supersaturations needed for ice-particle nucleation.

  9. A case study in scanner optimisation.

    PubMed

    Dudley, N J; Gibson, N M

    2014-02-01

    Ultrasound scanner preset programmes are factory set or tailored to user requirements. Scanners may, therefore, have different settings for the same application, even on similar equipment in a single department. The aims of this study were: (1) to attempt to match the performance of two scanners, where one was preferred and (2) to assess differences between six scanners used for breast ultrasound within our organisation. The Nottingham Ultrasound Quality Assurance software was used to compare imaging performance. Images of a Gammex RMI 404GS test object were collected from six scanners, using default presets, factory presets and settings matched to a preferred scanner. Resolution, low contrast performance and high contrast performance were measured. The performance of two scanners was successfully matched, where one had been preferred. Default presets varied across the six scanners, three different presets being used. The most used preset differed in settings across the scanners, most notably in the use of different frequency modes. The factory preset was more consistent across the scanners, the main variation being in dynamic range (55-70 dB). Image comparisons showed significant differences, which were reduced or eliminated by adjustment of settings to match a reference scanner. It is possible to match scanner performance using the Nottingham Ultrasound Quality Assurance software as a verification tool. Ultrasound users should be aware that scanners may not behave in a similar fashion, even with apparently equivalent presets. It should be possible to harmonise presets by consensus amongst users.

  11. Mapping Regional Drought Vulnerability: a Case Study

    NASA Astrophysics Data System (ADS)

    Karamouz, M.; Zeynolabedin, A.; Olyaei, M. A.

    2015-12-01

    Drought is among the natural disaster that causes damages and affects many people's life in many part of the world including in Iran. Recently, some factors such as climate variability and the impact of climate change have influenced drought frequency and intensity in many parts of the world. Drought can be divided into four categories of meteorological, hydrological, agricultural and social-economic. In meteorological the important feature is lack of rainfall. In hydrological drought river flows and dam storage are considered. Lack of soil moisture is the key factor in agricultural droughts while in social-economic type of drought the relation between supply and demand and social-economic damages due to water deficiency is studied. While the first three types relates to the lack of some hydrological characteristics, social-economic type of drought is actually the consequence of other types expressed in monetary values. Many indices are used in assessing drought; each has its own advantages and disadvantages and can be used for specific types of drought. Therefore knowing the types of drought can provide a better understanding of shortages and their characteristics. Drought vulnerability is a concept which shows the likelihood of damages from hazard in a particular place by focusing on the system status prior to the disaster. Drought vulnerability has been viewed as a potential for losses in the region due to water deficiency at the time of drought. In this study the application of vulnerability concept in drought management in East Azarbaijan province in Iran is investigated by providing vulnerability maps which demonstrates spatial characteristics of drought vulnerability. In the first step, certain governing parameters in drought analysis such as precipitation, temperature, land use, topography, solar radiation and ground water elevation have been investigated in the region. They are described in details and calculated in suitable time series. Vulnerabilities

    2012-01-01

    Health care aides (HCAs) are the backbone of the home care system and provide a range of services to people who, for various reasons related to chronic conditions and aging, are not able to take care of themselves independently. The demand for HCA services will increase and the current HCA supply will likely not keep up with this increasing demand without fundamental changes in the current environment. Information and communication technology (ICT) can address some of the workflow challenges HCAs face. In this project, we conducted an ethnographic study to document and analyse HCAs' workflows and team interactions. Based on our findings, we designed an ICT tool suite, integrating easily available existing and newly developed (by our team) technologies to address these issues. Finally, we simulated the deployment of our technologies, to assess the potential impact of these technological solutions on the workflow and productivity of HCAs, their healthcare teams and client care.

  16. Economics and extended longevity: a case study.

    PubMed

    Gori, G B; Richter, B J; Yu, W K

    1984-07-01

    Preventive and therapeutic advances have brought life expectancy in the United States to well over 70 years and have shifted mortality causes from acute to chronic diseases, the determinants of which are genetics, lifestyle, the environment, and aging itself. Plausible approaches to chronic disease prevention are likely to increase longevity further, with some foreseeable effects on demographic and economic projections. Primarily, longevity advances would swell forecasts of population size, and would thus have to be met by production advances in order to maintain or improve living standards. This study, a restricted example, considers the probable demographic and economic consequences of a limited prevention program in the context of the Ford Motor Company, based on actual experience and certain expectations up to the year 2000. According to the results, prevention would reduce outlays for life insurance, disability, and health care, but would also generate the higher costs of extending pension plans. Undoubtedly, prevention will continue to be highly ranked in society's pursuit of happiness, and society must prepare to meet its effects with appropriate social and economic policies.

    1994-08-01

    Three cases of malignant transformation within spiradenoma are described. All of them occurred close to the elbow. In every case we found a benign component, characteristic of the spiradenoma, and a structure of carcinoma, which in some areas showed transition into the spiradenoma. In one case the structure of the spiradenocarcinoma resembled that of the spiradenoma, whereas in the remaining two cases adenocarcinoma was the malignant counterpart of the tumor. We performed immunohistochemical studies and revealed various intensities of expression of cytokeratins and epithelial membrane antigen and a dearth of S-100 protein, vimentin, and carcinoembryonic antigen in the examined cases of spiradenocarcinoma.

    Pryor, H. E.

    1976-01-01

    The managers of the NASA Scientific and Technical Information System consistently maintain that whatever scientific and technical information services and products are provided must be geared primarily to user needs and not simply system compatibility and convenience. A system evaluation study begun in 1973 and continued to the present is described. The thrust of this on-going examination is to regularly evaluate the usefulness of the present information system to those it is intended to serve, engineers and scientists working in their professional roles, and to identify areas and ways in which the system can be made more responsive to user needs. Techniques used have covered the range from personal, in-depth interviews to widely distributed questionnaires. The findings have been positive. Many refinements made to on-going programs and projects and new endeavors begun in direct response to stated user needs are discussed. In the main these needs are not unreasonable and thus can be responded to with cost effective system modifications.

  5. A Case for Hypogravity Studies Aboard ISS

    NASA Technical Reports Server (NTRS)

    Paloski, William H.

    2014-01-01

    Future human space exploration missions being contemplated by NASA and other spacefaring nations include some that would require long stays upon bodies having gravity levels much lower than that of Earth. While we have been able to quantify the physiological effects of sustained exposure to microgravity during various spaceflight programs over the past half-century, there has been no opportunity to study the physiological adaptations to gravity levels between zero-g and one-g. We know now that the microgravity environment of spaceflight drives adaptive responses of the bone, muscle, cardiovascular, and sensorimotor systems, causing bone demineralization, muscle atrophy, reduced aerobic capacity, motion sickness, and malcoordination. All of these outcomes can affect crew health and performance, particularly after return to a one-g environment. An important question for physicians, scientists, and mission designers planning human exploration missions to Mars (3/8 g), the Moon (1/6 g), or asteroids (likely negligible g) is: What protection can be expected from gravitational levels between zero-g and one-g? Will crewmembers deconditioned by six months of microgravity exposure on their way to Mars experience continued deconditioning on the Martian surface? Or, will the 3/8 g be sufficient to arrest or even reverse these adaptive changes? The implications for countermeasure deployment, habitat accommodations, and mission design warrant further investigation into the physiological responses to hypogravity. It is not possible to fully simulate hypogravity exposure on Earth for other than transient episodes (e.g., parabolic flight). However, it would be possible to do so in low Earth orbit (LEO) using the centrifugal forces produced in a live-aboard centrifuge. As we're not likely to launch a rotating human spacecraft into LEO anytime in the near future, we could take advantage of rodent subjects aboard the ISS if we had a centrifuge that could accommodate the rodent

    Bagán, Jose V.; Sanchis, Jose M.; Carbonell, Enrique

    2012-01-01

    Objective: To compare the risk factors and clinical manifestations of patients with temporomandibular disorders (TMDs) diagnosed according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) (axis I) versus an age and gender matched control group. Study Design: A total of 162 patients explored according to the RDC/TMD (mean age 40.6±18.8 years, range 7-90; 11.1% males and 88.9% females) were compared with 119 controls, measuring differences in TMD risk factors (sleep disturbances, stress, psychoactive medication, parafunctions, loss of posterior support, ligament hyperlaxity) and clinical variables (joint sounds, painful muscle and joint palpation, maximum aperture). Results: Myofascial pain (MFP) (single or multiple diagnoses) was the most frequent diagnosis (42%). The most common diagnostic combination was MFP plus arthralgia (16.0%). Statistically significant differences were observed in clenching (OR 2.3; 95%CI: 1.4-3.8) and in maximum active aperture (MAA) on comparing the two groups both globally (TMD vs. controls) (patients 36.7±8.6 mm, controls 43.1±5.8 mm; F=45.41, p = 0.000) and on comparing according to diagnostic categories. MFP explained most of the observed differences in the risk factors: stress perception (OR=1.98;I.C.:1.01-3.89), psychoactive medication (OR=2.21; I.C.:1.12-4.37), parafunctions (OR=2.14;I.C.:1.12-4.11), and ligament laxity (OR=2.6;I.C.:1.01-6.68). Joint sounds were more frequent in patients with MFP (39.7% vs. 24.0%; χ2=4.66; p=0.03), and painful joint palpation was more common in patients with disc displacement with reduction (DDWR)(15.9% vs. 5.0%; χ2 = 5.2; p = 0.02) and osteoarthrosis (20.8% vs. 5.0%; χ2 = 7.0; p = 0.008). Conclusions: There is a high prevalence of signs and symptoms of TMDs in the general population. Significant differences are observed in clenching and MAA between patients and controls considered both globally and for each diagnostic category individually. The analyzed risk

    2016-01-01

    Cellular angiofibroma is a mesenchymal tumor that affects both genders. Nucci et al. first described it in 1997. Cellular angiofibroma is generally a small and asymptomatic mass that primarily arises in the vulvar-vaginal region, although rare cases have been reported in the pelvic and extrapelvic regions. It affects women most often during the fifth decade of life. The treatment requires simple local excision due to low local recurrence and no chance of metastasization. The current study presents a case of angiofibroma in the vulvar region that measured approximately 20 cm. PMID:27293929

    Estimating certain attributes within a geological body whose exact boundary is not known presents problems because of the lack of information. Estimation may result in values that are inadmissible from a geological point of view, especially with attributes which necessarily must be zero outside the boundary, such as the thickness of the oil column outside a reservoir. A simple but effective way to define the boundary is to use indicator kriging in two steps, the first for the purpose of extrapolating control points outside the body, the second to obtain a weighting function which expresses the uncertainty attached to estimations obtained in the boundary region. ?? 1993 International Association for Mathematical Geology.

    A dean at a private school of nursing implemented a leadership development program for early- to mid-career nursing faculty consisting of one 4-hour evening session per academic quarter for 7 quarters. Eight faculty members who had expressed interest in assuming a leadership role or been recommended by their supervisors as having strong leadership potential were invited to join. Program topics included leadership pathways, legal issues, budgeting and governance, diversity, the political arena, human resources, and student issues. Interviews with participants revealed 6 themes: the support a peer cohort provided, a desire for real-life application, a lack of previous exposure to related content or experiences, new perceptions of themselves as academic nurse leaders, the value of the program as preparation for academic nursing leadership roles, and broad program applicability.

    LoFaro, T.; Kopell, N.

    1995-12-31

    We discuss a method by which the dynamics of a network of coupled neurons can be captured in a one-dimensional map. The network used as an example of this technique consists of a pair of neurons, one of which is an endogenous burster and the other excitable, but not bursting in the absence of phasic input. The reduction is accomplished by decomposing the flow into fast and slow subsystems, each operating on a distinct time scale. A {open_quotes}map of knees{close_quotes} is constructed using singular perturbation techniques. A concise expression for this map is developed by introducing time coordinates to each stable branch of the slow manifold. The compression associated with the fast subsystem is used to determine the qualitative properties of the map.

    To attain and sustain a competitive advantage organizations are continually faced with the need to change their structures, processes and technologies. Converting to new technology and implementing a new information management system in an organization results in inevitable changes in organizational procedures impacting on the people involved. A major problem encountered during this process is resistance to change, which may contribute to total failure of this system. Change management is the process that can be used to negate this impact and assist employees in transitioning to a new way of doing things.

    I will tell you how we transferred a technology from the US Department of Energy`s Pacific Northwest Laboratory to the private sector. I`ll begin by telling about the technology and what it does. Then I`ll tell you how we found a commercial partner to market the technology. And I`ll end by telling you some of the lessons we learned and what our customer thinks about the partnership. This is a success for two reasons. First, the people who developed the technology had faith in its potential. And second, they took an active part in the transfer; they didn`t sit back and wait for someone else to do it. That reminds me of Joe. Night after night, Joe prayed for help in winning the lottery, but his prayers went unanswered. Finally he cried out in desperation: ``Lord, give me a break! Please let me win the lottery!`` Suddenly, lightning flashed across the sky and thunder crashed around him. Then, he heard a voice from above: ``Joe! You give ME a break! BUY A TICKET!`` To succeed in tech transfer, you`ve got to have more than faith. You`ve got to buy a ticket. You`ve got to invest time, energy, imagination, and effort.

    This paper describes a research and innovation platform for the development of ideas relating to the investigation of blood perfusion in peripheral tissue. The Loughborough Innovation Platform for Health Technologies (LIPHT) can be used to demonstrate the use of the research and innovation pipe-line in more than one dimension. For this paper the first dimension considered is that of 'blue sky' idea through to their exploitation for the benefit of users and at the same time creating a wealth stream; the second dimension is the changing market as the ideas develop--from a hospital-based instrument operated by clinicians through to a point and click device for the use by the knowledgeable layman in the community. The starting point for these developments is a medical device known to many people as the 'finger clip' that measures arterial blood oxygen saturation; the end point is an optical device capable of imaging blood perfusion.

    PubMed

    Pozos-Estrada, Oscar; Fuentes-Mariles, Oscar A; Pozos-Estrada, Adrian

    2012-01-01

    This paper presents a case study of an existing wastewater rising main (WWRM) in which an extreme transient event produced by simultaneous power failure of the pumps caused the rupture of a 1.2 m (48 in) prestressed concrete cylinder pipe (PCCP), causing an important leakage of sewage. The event and the methodology followed in order to validate the diagnostics of the failure are described. The detail study included in situ observation of the system, experimental investigation in a setup, hydraulic analysis, as well as details of the structural strength of the WWRM. After the extensive investigation and several simulations of fluid transients for different scenarios and flow conditions, it was found that stationary small gas pockets accumulated at high points of the WWRM were identified as the principal contributory factor of the failure. This case study serves as clear warning of the consequences of operating a WWRM with gas pockets at its high points.

    1992-01-01

    Total Quality Management (TQM) is becoming more important as a way to improve productivity. One of the technical aspects of TQM is a system called the Taguchi method. This is an optimization method that, with a few precautions, can reduce test effort by an order of magnitude over conventional techniques. The Taguchi method is specifically designed to minimize a product's sensitivity to uncontrollable system disturbances such as aging, temperature, voltage variations, etc., by simultaneously varying both design and disturbance parameters. The analysis produces an optimum set of design parameters. A 3-day class on the Taguchi method was held at the Marshall Space Flight Center (MSFC) in May 1991. A project was needed as a follow-up after the class was over, and the motor controller was selected at that time. Exactly how to proceed was the subject of discussion for some months. It was not clear exactly what to measure, and design kept getting mixed with optimization. There was even some discussion about why the Taguchi method should be used at all.

    SciTech Connect

    Abercrombie, Robert K; Sheldon, Frederick T; Mili, Ali

    2011-01-01

    Vulnerabilities in a system may have widely varying impacts on system security. In practice, security should not be defined as the absence of vulnerabilities. In practice, security should not be quantified by the number of vulnerabilities. Security should be managed by pursuing a policy that leads us first to the highest impact vulnerabilities. In light of these observations, we argue in favor of shifting our focus from vulnerability avoidance/removal to measurable security attributes. To this effect, we recommend a logic be used for system security, which captures/represents security properties in quantifiable, verifiable, measurable terms so that it is possible to reason about security in terms of its observable/perceptible effects rather than its hypothesized causes. This approach is orthogonal to existing techniques for vulnerability avoidance, removal, detection, and recovery, in the sense that it provides a means to assess, quantify, and combine these techniques.

    1994-05-01

    A man with an infarction of his inferior temporal and occipital association cortex bilaterally, which spared primary visual cortex, had impaired visual recognition of objects, faces, colors, words, and gestures. Analysis of visual function indicated that the recognition failures resulted from an agnosia, rather than elemental visual impairment. Whereas his impairment of gesture recognition appeared to be related to an associative agnosia, his inability to recognize objects was related to an apperceptive agnosia. There may be four subtypes of apperceptive agnosia: one where the internal object representations or structural descriptions are impaired, another where an adequate percept cannot be derived, a third where the internal referent and percept are dissociated, and a fourth where both levels are impaired. Our patient demonstrated a failure to relate individual elements to the whole, a failure to integrate multiple elements, and a reliance on global perception. He had normal object imagery. These results suggest that, whereas internal representations were intact, he was unable to form adequate perceptual representations.

    PubMed Central

    Little, Lisa

    2007-01-01

    Objective To synthesize information about nurse migration in and out of Canada and analyze its role as a policy lever to address the Canadian nursing shortage. Principal Findings Canada is both a source and a destination country for international nurse migration with an estimated net loss of nurses. The United States is the major beneficiary of Canadian nurse emigration resulting from the reduction of full-time jobs for nurses in Canada due to health system reforms. Canada faces a significant projected shortage of nurses that is too large to be ameliorated by ethical international nurse recruitment and immigration. Conclusions The current and projected shortage of nurses in Canada is a product of health care cost containment policies that failed to take into account long-term consequences for nurse workforce adequacy. An aging nurse workforce, exacerbated by layoffs of younger nurses with less seniority, and increasing demand for nurses contribute to a projection of nurse shortage that is too great to be solved ethically through international nurse recruitment. National policies to increase domestic nurse production and retention are recommended in addition to international collaboration among developed countries to move toward greater national nurse workforce self sufficiency.

  11. Assessing Biofuel Crop Invasiveness: A Case Study

    PubMed Central

    Buddenhagen, Christopher Evan; Chimera, Charles; Clifford, Patti

    2009-01-01

    Background There is widespread interest in biofuel crops as a solution to the world's energy needs, particularly in light of concerns over greenhouse-gas emissions. Despite reservations about their adverse environmental impacts, no attempt has been made to quantify actual, relative or potential invasiveness of terrestrial biofuel crops at an appropriate regional or international scale, and their planting continues to be largely unregulated. Methodology/Principal Findings Using a widely accepted weed risk assessment system, we analyzed a comprehensive list of regionally suitable biofuel crops to show that seventy percent have a high risk of becoming invasive versus one-quarter of non-biofuel plant species and are two to four times more likely to establish wild populations locally or be invasive in Hawaii or in other locations with a similar climate. Conclusions/Significance Because of climatic and ecological similarities, predictions of biofuel crop invasiveness in Hawaii are applicable to other vulnerable island and subtropical ecosystems worldwide. We demonstrate the utility of an accessible and scientifically proven risk assessment protocol that allows users to predict if introduced species will become invasive in their region of interest. Other evidence supports the contention that propagule pressure created by extensive plantings will exacerbate invasions, a scenario expected with large-scale biofuel crop cultivation. Proactive measures, such as risk assessments, should be employed to predict invasion risks, which could then be mitigated via implementation of appropriate planting policies and adoption of the “polluter-pays” principle.

  12. Public opponents of vaccination: a case study.

    PubMed

    2003-12-01

    Opposition to mass childhood vaccination is a world-wide phenomenon, particularly in industrialised countries. Unfounded claims about vaccination are perpetuated by parental lobby groups and individual spokespeople, some of whom have a medical or scientific background. This article focuses on one such spokesperson who has achieved particular notoriety. Dr. Viera Scheibner is a retired micropalaeontologist, without any formal training in health-related sciences, who tours the world claiming that vaccines are ineffective and dangerous and lead to a host of ills such as cancer and asthma. Professionals in public health or the clinical arena are from time to time called upon to publicly respond to her, or similar, claims disseminated during tours of Europe, North America or Australasia and in books and articles. Health professionals have expressed at how such spokespersons misrepresent the evidence on vaccine safety, resulting in the potential to undermine public confidence in immunisation. Media coverage, or proposed coverage, particularly of her more extreme claims, often makes health professionals engaged in immunisation feel obliged to respond. This paper describes Viera Scheibner's approach, which follows a repetitious path and is representative of that taken by other public opponents of immunisation. We conclude by suggesting how health professionals might respond in the public arena.

  13. Questioning nuclear waste substitution: a case study.

    PubMed

    Marshall, Alan

    2007-03-01

    This article looks at the ethical quandaries, and their social and political context, which emerge as a result of international nuclear waste substitution. In particular it addresses the dilemmas inherent within the proposed return of nuclear waste owned by Japanese nuclear companies and currently stored in the United Kingdom. The UK company responsible for this waste, British Nuclear Fuels Limited (BNFL), wish to substitute this high volume intermediate-level Japanese-owned radioactive waste for a much lower volume of much more highly radioactive waste. Special focus is given to ethical problems that they, and the UK government, have not wished to address as they move forward with waste substitution. The conclusion is that waste substitution can only be considered an ethical practice if a set of moderating conditions are observed by all parties. These conditions are listed and, as of yet, they are not being observed.

  5. ERP implementation in hospitals: a case study.

    PubMed

    Agarwal, Divya; Garg, Poonam

    2012-01-01

    In a competitive healthcare sector, hospitals have to focus on their processes in order to deliver high-quality care while at the same time reducing costs. Many hospitals have decided to adopt one or another Enterprise Resource Planning (ERP) system to improve their businesses, but implementing an ERP system can be a demanding endeavour. The systems are so difficult to implement that some are successful; many have failed, causing multimillion dollar losses. The challenge of ERP solutions lie in implementation because they are complex, time consuming and expensive too. This paper describes the various process workflows and phases of ERP implementation at Fortis Hospital Cunningham Road, Bangalore, India. This knowledge will provide valuable insights for the researchers and practitioners to understand the different process workflows and to make informed decisions when implementing ERP in any hospital.

    PubMed

    Hartman, P

    1979-01-01

    Communications and development in the broadest sense of the terms are examined in relation to evaluation of the work of the Communication Foundation for Asia (CFA). CFA produces, in conjunction with public and private development agencies, flip-charts, comics, a fieldworker's handbook for use in family planning education, sound cassette magazines for agricultural extension work, booklets and sound-slides on forming cooperatives, and other educational materials. CFA operates in the Philippines. A developmental radio drama produced by CFA delivered a pro-development message, one that tells people they can do something about their conditions/situations, compared to the passive, consumer-oriented commercial radio drama. The most prominent theme was achievement. The characters had complex motivations and displayed wide range of motives. Like other forms of propaganda, developmental radio drama is not welcomed by radio station owners. Not many people in the industry perceive the opportunity for increasing overall development and economic growth. All pressures from commercial radio are in consumerist directions while developmental drama encourages production.

    Sporea, Dan; Massa, Nicholas; Donnelly, Judith F.; Hanes, Fenna

    2007-06-01

    From 2004, the Center for Science Education and Training (CSET) participated to the European Union-funded educational network "Hands-on Science". The aim of the Romanian team was to transform teachers and students from end-users of educational aids to active designers and developers of instructional materials. Several science fields were identified, including photonics. The team at CSET is now focusing on: lasers and their applications, optical fiber communications, solar energy as a sustainable source, and the use of optical spectroscopy in physics and chemistry. CSET initiated an international collaboration with the New England Board of Higher Education (NEBHE) in Boston, Mass., when the Center enrolled an experienced Romanian high school science teacher in a twelve-week "Introduction to Photonics" laboratory-based professional development course. The course was developed by NEBHE through an Advanced Technological Education (ATE) program grant from National Science Foundation and is designed for high school and community college educators from both science and technology instructional areas. The paper reports the experience of this international participation which was made possible since the course is delivered via the Internet by Three Rivers Community College, Norwich, Conn. Its impact on photonics education in Romania and the USA is analyzed, as the participant teacher shares her experiences with teachers and faculty in the "Introduction to Photonics" course and with those enrolled into the Romanian "Hands-on-Science" program.

    Baker, J.

    1997-12-31

    Partnerships and cooperative agreements abound in the environmental arena today. This paper briefly highlights the collaborative approach used by the International Cooperative for Ozone Layer Protection (ICOLP). ICOLP has helped international members and non-members to eliminate most of the ozone-depleting solvents from manufacturing processes through the exchange of technical information in a non-proprietary manner. By using alternatives, companies and governments have realized savings in the multiple millions of dollars. Advantages of participating in cooperative environmental partnerships may include: (1) improved access and exchange of information, (2) cost minimization, (3) promotion and facilitation of business opportunities, (4) improved dialogue between groups, (5) coordinated approach to complex issues, and (6) technology development and transfer opportunities.

    PubMed

    Sudano, Laura E; Patterson, Jo Ellen; Lister, Zephon D

    2015-09-01

    As the field of collaborative care, or integrated behavioral health, continues to develop, lessons are learned from attempts to establish such programs (Sieber et al., 2012; Unützer, 2014). Part of the success of collaborative care programs is the function of an interdisciplinary team. In this article, faculty from University of San Diego (USD) and University of California, San Diego (UCSD) share changes needed to curriculum and career development to support leadership and teamwork skills essential to program development, implementation, and sustainability for integrated behavioral health. This article uses Unützer's (2014) 4 factors of creating a successful collaborative care program (i.e., shared vision, leadership, staffing, and financial sustainability) to discuss implications for effective collaboration between 2 universities and the training of primary care providers in teamwork and leadership skills for overcoming barriers and pitfalls to expand collaborative care beyond their initial training.

  18. Self-socialization: a case study of a parachute child.

    PubMed

    Newman, Philip R; Newman, Barbara M

    2009-01-01

    The theoretical concept of self-socialization suggests that an individual is able to reflect on the self, formulate a vision of a future self, set goals, and take actions that create or alter the developmental trajectory. This case study of a parachute child illustrates how a person constructs her life from a very young age, drawing on a profound capacity for personal agency to overcome obstacles, identify resources, and internalize values to build a life structure. A model of the psychosocial process of self-socialization emerges from this case. Following the disruption of a well-defined trajectory, self-socialization is observed as a sequence of actions, reflection, correction, and new actions. Self-socialization is possible when a strong sense of self-efficacy is applied to attaining internalized values and goals.

    Introduction An association between psoriasis and metabolic syndrome has been established in previous studies. Lichen Planus (LP) is also a chronic inflammatory disease morphologically related to psoriasis and few studies have shown association of metabolic derangements in LP. Aim To study the association of metabolic derangements in LP. Materials and Methods A prospective case control study was undertaken for a period of one year. Age and sex matched patients of LP and other non-inflammatory diseases were taken as cases and controls respectively. Data on height, weight, lipid profile and fasting blood glucose levels were collected for all the patients. Body Mass Index (BMI) was calculated. Results A total of 80 patients were recruited, 40 cases and 40 controls. The mean values for all the lipid and glucose parameters were high in cases as compared to controls with significant p-values. Conclusion In the present study metabolic derangements were seen in patients with LP. PMID:28050485

  1. A case study of nursing case management in a rural hospital.

    PubMed

    Anderson-Loftin, W; Wood, D; Whitfield, L

    1995-01-01

    This article describes the process of implementing a New England model of case management in a rural hospital and the modifications necessary in adapting an urban model to a rural setting. Nursing case management at this institution has been associated with a decrease in the length of stay by 1.7 days at an estimated cost savings of $65,932 for the 16-month study period. Case management has also been instrumental in improving quality of care through a program of continuous quality improvement and in redesigning the RN role. The vision for the future is to extend the nurse case manager role outside the hospital walls to the community in a collaborative plan that would bill nursing services through physicians' offices.

  9. Epistemological Syncretism in a Biology Classroom: A Case Study

    NASA Astrophysics Data System (ADS)

    Bennett, William D.; Park, Soonhye

    2011-02-01

    In teaching science, the beliefs of teachers may come into conflict and inhibit the implementation of reformed teaching practice. An experienced biology teacher, Mr. Hobbs, was found to have two different sets of epistemological beliefs while his classroom practice was predominantly teacher-centered. A case study was then performed in order to investigate the underlying issues that contributed to his classroom practice. Data sources included preliminary and follow-up interviews and classroom observations. Data analysis indicated that factors that prevented the epistemological conflict from reaching a resolution included Mr. Hobbs' beliefs about learning, contextual teaching factors, personal experiences as a student, and views of the nature of science. The findings from this case indicate that science teachers possess complex belief systems that are not immediately obvious to either the teacher or science teacher educators, and science teacher educators need to address teacher beliefs when they encourage teachers to implement reformed teaching practices.

    1990-09-22

    We have prospectively studied 158 cases of acute hepatitis delta observed during the last 7 years in a general hospital. Among them 136 were male and 22 female. The mean age was 22.7 years with a range between 16 and 61 years. The epidemiologic factors were drug addiction by parenteral route in 145 cases (92%), sexual transmission in 5 (3%), post transfusional in 2 (1%) and unknown in 6 (4%). With respect to the delta type infection, 105 cases (66%) were coinfections with type B and delta, and 53 patients had a type delta superinfection (34%). The clinical course was a fulminant hepatitis in three cases (two cases of coinfection B and delta an one case of delta superinfection), and an acute benign hepatitis in 155 patients. The follow-up of 118 patients revealed that 96% of coinfections by type B and delta evolved to the chronicity showing findings of active chronic hepatitis or hepatic cirrhosis. It should be noted that in 4 cases of superinfection delta type (11%) the HBsAg was negative after several months of positivity. In these patients the level of transaminases normalized and the hepatic histology evidenced alterations of chronic active hepatitis (2 cases) and hepatic cirrhosis (2 cases) without identification of tissular delta antigen.

  14. Thinking like a scientist: innateness as a case study.

    PubMed

    Knobe, Joshua; Samuels, Richard

    2013-01-01

    The concept of innateness appears in systematic research within cognitive science, but it also appears in less systematic modes of thought that long predate the scientific study of the mind. The present studies therefore explore the relationship between the properly scientific uses of this concept and its role in ordinary folk understanding. Studies 1-4 examined the judgments of people with no specific training in cognitive science. Results showed (a) that judgments about whether a trait was innate were not affected by whether or not the trait was learned, but (b) such judgments were impacted by moral considerations. Study 5 looked at the judgments of both non-scientists and scientists, in conditions that encouraged either thinking about individual cases or thinking about certain general principles. In the case-based condition, both non-scientists and scientists showed an impact of moral considerations but little impact of learning. In the principled condition, both non-scientists and scientists showed an impact of learning but little impact of moral considerations. These results suggest that both non-scientists and scientists are drawn to a conception of innateness that differs from the one at work in contemporary scientific research but that they are also both capable of 'filtering out' their initial intuitions and using a more scientific approach.

    Taylor, Ruth; Thomas-Gregory, Annette

    2015-06-10

    This article describes case study research for nursing and healthcare practice. Case study research offers the researcher an approach by which a phenomenon can be investigated from multiple perspectives within a bounded context, allowing the researcher to provide a 'thick' description of the phenomenon. Although case study research is a flexible approach for the investigation of complex nursing and healthcare issues, it has methodological challenges, often associated with the multiple methods used in individual studies. These are explored through examples of case study research carried out in practice and education settings. An overview of what constitutes 'good' case study research is proposed.

    PubMed

    Crumbley, D R; Ice, R C; Cassidy, R

    1999-01-01

    The wound Care Clinic at Naval Hospital Charleston is a nurse-managed ambulatory clinic that has demonstrated the successful application of nursing case management in caring for patients with chronic and complex wounds. Nursing case management is an outcomes-based system of assessment, planning, provision of nursing services, coordination of interdisciplinary efforts, education, and referral. Nursing case management has been shown, in the literature and at Naval Hospital Charleston, to be an extension of role of professional nursing practice and results in decreased costs, improved quality of care, faster wound healing times, decreased complications, and greater coordination of care between specialty disciplines. These positive results are illustrated in several case studies. Nursing case management has many implications for the successful implementation of any healthcare delivery system where decreased costs and improved quality of care are valued, and it has special benefit in the complex management of chronically ill patients.

    Bourgeois, Nicolas; Chavant, François; Lafay-Chebassier, Claire; Leveziel, Nicolas; Pérault-Pochat, Marie-Christine

    2016-09-01

    Retina is the part of the eye suffering most damage from pharmaceutical molecules. Drug-induced retinopathies have been described but data are scarce and sometimes conflicting especially concerning its potential seriousness. The aim of this study was to investigate potential associations between drugs and retinal disorders using the French Pharmacovigilance data. We used the case/non-case method in the French PharmacoVigilance Database (FPVD) to identify drugs able to induce retinopathies. Cases were reports of retinal disorders in the FPVD between January 2008 and December 2012. Non-cases were all other reports during the same period. To assess the association between retinopathy and drug intake, we calculated the odds-ratio (OR) [with their 95% confidence intervals] for all drugs associated with at least 3 cases of retinopathy. Among the 123 687 adverse drug reactions recorded during the studied period, we identified 164 cases of retinal disorders. Significant associations were found for 11 drugs. The main therapeutic classes were antirhumatismals (hydroxychloroquine, chloroquine and etanercept: 18 cases), anti-infective (ribavirine, PEG-interferon-alfa-2a and cefuroxime: 16 cases) and antineoplastic drugs (imatinib and letrozole: 8 cases. Three other drugs were also found: raloxifene (5 cases), erythropoietin beta (4 cases) and ranibizumab (3 cases). Taking into account the limits of the methodology, our study confirmed the association between retinopathy and some expected drugs such as aminoquinolines, interferons, imatinib or ranibizumab. Other drugs like erythropoietin beta, cefuroxime, letrozole and etanercept were significantly associated with retinal disorders although this was not or poorly described in the literature. Thus, further prospective studies are necessary to confirm such associations.

    2016-05-22

    Case study research is a comprehensive method that incorporates multiple sources of data to provide detailed accounts of complex research phenomena in real-life contexts. However, current models of case study research do not particularly distinguish the unique contribution observation data can make. Observation methods have the potential to reach beyond other methods that rely largely or solely on self-report. This article describes the distinctive characteristics of case study observational research, a modified form of Yin's 2014 model of case study research the authors used in a study exploring interprofessional collaboration in primary care. In this approach, observation data are positioned as the central component of the research design. Case study observational research offers a promising approach for researchers in a wide range of health care settings seeking more complete understandings of complex topics, where contextual influences are of primary concern. Future research is needed to refine and evaluate the approach.

  13. Model Checking Failed Conjectures in Theorem Proving: A Case Study

    NASA Technical Reports Server (NTRS)

    Pike, Lee; Miner, Paul; Torres-Pomales, Wilfredo

    2004-01-01

    Interactive mechanical theorem proving can provide high assurance of correct design, but it can also be a slow iterative process. Much time is spent determining why a proof of a conjecture is not forthcoming. In some cases, the conjecture is false and in others, the attempted proof is insufficient. In this case study, we use the SAL family of model checkers to generate a concrete counterexample to an unproven conjecture specified in the mechanical theorem prover, PVS. The focus of our case study is the ROBUS Interactive Consistency Protocol. We combine the use of a mechanical theorem prover and a model checker to expose a subtle flaw in the protocol that occurs under a particular scenario of faults and processor states. Uncovering the flaw allows us to mend the protocol and complete its general verification in PVS.

    2009-09-01

    The number of dementia patients is growing, and they require a variety of services, making integrated care essential for the ability to continue living in the community. Many healthcare systems in developed countries are exploring new approaches for delivering health and social care. The purpose of this study was to describe and analyse a new approach in extensive case management programmes concerned with long-term dementia care in The Netherlands. The focus is on the characteristics, and success and failure factors of these programmes.A multiple case study was conducted in eight regional dementia care provider networks in The Netherlands. Based on a literature study, a questionnaire was developed for the responsible managers and case managers of the eight case management programmes. During 16 semistructured face-to-face interviews with both respondent groups, a deeper insight into the dementia care programmes was provided. Project documentation for all the cases was studied. The eight programmes were developed independently to improve the quality and continuity of long-term dementia care. The programmes show overlap in terms of their vision, tasks of case managers, case management process and the participating partners in the local dementia care networks. Differences concern the targeted dementia patient groups as well as the background of the case managers and their position in the local dementia care provider network. Factors for success concern the expert knowledge of case managers, investment in a strong provider network and coherent conditions for effective inter-organizational cooperation to deliver integrated care. When explored, caregiver and patient satisfaction was high. Further research into the effects on client outcomes, service use and costs is recommended in order to further analyse the impact of this approach in long-term care. To facilitate implementation, with a focus on joint responsibilities of the involved care providers, policy

The Coefficient of performance (COP) to run such refrigerator is estimated after numerical simulation of major components namely, evaporator, condenser and a capillary tube. The simulation was done to obtain an effective cooling temperature and the results were compared with measured temperatures. Calculation proves to be in conformity with the actual model.

  4. Leber's congenital amaurosis. A retrospective study of 33 cases and a histopathological study of one case.

    PubMed

    Noble, K G; Carr, R E

    1978-05-01

    This report is a retrospective study of 33 patients seen over a 16-year period in whom a diagnosis of Leber's congenital amaurosis was made. The findings of an autosomal recessive heredity in 33%, connatal blindness (visual acuity less than 20/200) in 95%m nystagmus in 75%, and a markedly abnormal electroretinogram in 100% is in agreement with the findings of previously published large series. The difficulty in making the correct diagnosis initially was related to the wide variety of fundus findings and a high association (30%) of central nervous system disease. In the differential diagnosis of connatal blindness, only Leber's congenital amaurosis exhibits an absent or markedly diminished response on electroretinogram. The histopathologic findings in a 6-month-old infant with this disorder are compared with those of previously published reports.

    Reaching zero defects is vital in medication service. Medication error can be reduced if the causes are recognized. The purpose of this study is to search for a conceptual framework of the causes of medication error in Thailand and to examine relationship between these factors and its importance. The study was carried out upon an in-depth case study and survey of hospital personals who were involved in the drug use process. The structured survey was based on Emergency Care Research Institute (ECRI) (2008) questionnaires focusing on the important factors that affect the medication safety. Additional questionnaires included content to the context of Thailand's private hospital, validated by five-hospital qualified experts. By correlation Pearson analysis, the result revealed 14 important factors showing a linear relationship with drug administration error except the medication reconciliation. By independent sample t-test, the administration error in the hospital was significantly related to external impact. The multiple regression analysis of the detail of medication administration also indicated the patient identification before administration of medication, detection of the risk of medication adverse effects and assurance of medication administration at the right time, dosage and route were statistically significant at 0.05 level. The major implication of the study is to propose a medication safety model in a Thai private hospital. PMID:23985110

  6. Enrique: A case study of a gifted computer user

    SciTech Connect

    Sesko, S C

    2000-03-17

    The author has been investigating the affective and intellectual views that gifted children have about computers. These studies have used various methodological approaches in order to develop a broad perspective on the issues involved in this topic. The author has used survey instruments (Sesko, 1998) and interview techniques (Sesko, 1999) to capture both statistical and narrative data. The objective of this study is to explore in depth the interactions that one student has with the machine and its applications. The driver for this and the previous studies was the paucity of research in the area of gifted and talented children and their involvement with what has become the primary intellectual tool of the century (Turkel, 1984). The second reason is that it has been posited that the intellectual characteristics of gifted children should enable those who are interested in computers to achieve a high level of proficiency with either computer applications or programming. Further, the ability to learn things at a young age should allow gifted children who use computers to develop a large variety of computer-based activities. The author has shown evidence to support these ideas in previous work. Finally, as Hausman (1985) claims, facilities with computers should allow these children to create new activities for using computers. The author found no published research to demonstrate whether they do; but still believes the results of this case study strongly support Hausman's contentions.

  7. Feet swelling in a multistage ultraendurance triathlete: a case study

    Knechtle, Beat; Zingg, Matthias Alexander; Knechtle, Patrizia; Rosemann, Thomas; Rüst, Christoph Alexander

    2015-01-01

    Recent studies investigating ultraendurance athletes showed an association between excessive fluid intake and swelling of the lower limbs such as the feet. To date, this association has been investigated in single-stage ultraendurance races, but not in multistage ultraendurance races. In this case study, we investigated a potential association between fluid intake and feet swelling in a multistage ultraendurance race such as a Deca Iron ultratriathlon with ten Ironman triathlons within 10 consecutive days. A 49-year-old well-experienced ultratriathlete competed in autumn 2013 in the Deca Iron ultratriathlon held in Lonata del Garda, Italy, and finished the race as winner within 129:33 hours:minutes. Changes in body mass (including body fat and lean body mass), foot volume, total body water, and laboratory measurements were assessed. Food and fluid intake during rest and competing were recorded, and energy and fluid turnovers were estimated. During the ten stages, the volume of the feet increased, percentage body fat decreased, creatinine and urea levels increased, hematocrit and hemoglobin values decreased, and plasma [Na+] remained unchanged. The increase in foot volume was significantly and positively related to fluid intake during the stages. The poststage volume of the foot was related to poststage total body water, poststage creatinine, and poststage urea. This case report shows that the volume of the foot increased during the ten stages, and the increase in volume was significantly and positively related to fluid intake during the stages. Furthermore, the poststage volume of the foot was related to poststage total body water, poststage creatinine, and poststage urea. The continuous feet swelling during the race was most probably due to a combination of a high fluid intake and a progressive decline in renal function (ie, continuous increase in creatinine and urea), leading to body fluid retention (ie, increase in total body water).

    This case study describes the application of the principles of mindful eating to the treatment of a case of anorexia nervosa. While many clinicians currently use mindful eating in their treatment of binge eating disorder and bulimia, it also may benefit clients who restrict. The client in this case study is a 19-year-old college student with a BMI of 17.9 and daily restriction of approximately 900-1000 calories who exercises 1 hour daily. Over 15 sessions, she was introduced to the principle of mindful eating. There was an overall decline in restriction, her BMI raised to 19.5, and her caloric intake increased to approximately 1,500-2,000.

  14. A Case Study of a High School Fab Lab

    NASA Astrophysics Data System (ADS)

    Lacy, Jennifer E.

    This dissertation examines making and design-based STEM education in a formal makerspace. It focuses on how the design and implementation of a Fab Lab learning environment and curriculum affect how instructors and students see themselves engaging in science, and how the Fab Lab relates to the social sorting practices that already take place at North High School. While there is research examining design-based STEM education in informal and formal learning environments, we know little about how K-12 teachers define STEM in making activities when no university or museum partnership exists. This study sought to help fill this gap in the research literature. This case study of a formal makerspace followed instructors and students in one introductory Fab Lab course for one semester. Additional observations of an introductory woodworking course helped build the case and set it into the school context, and provided supplementary material to better understand the similarities and differences between the Fab Lab course and a more traditional design-based learning course. Using evidence from observational field notes, participant interviews, course materials, and student work, I found that the North Fab Lab relies on artifacts and rhetoric symbolic of science and STEM to set itself apart from other design-based courses at North High School. Secondly, the North Fab Lab instructors and students were unable to explain how what they were doing in the Fab Lab was science, and instead relied on vague and unsupported claims related to interdisciplinary STEM practices and dated descriptions of science. Lastly, the design and implementation of the Fab Lab learning environment and curriculum and its separation from North High School's low tech, design-based courses effectively reinforced social sorting practices and cultural assumptions about student work and intelligence.

    The specialization of contemporary academia necessitates the adoption of a multidisciplinary approach to study topics that cross multiple disciplines, including the area of medical ethics. However, the nature of multidisciplinary research is limited in some regards, further requiring some researchers to use interdisciplinary and transdisciplinary approaches. The authors present as a case study a research project in bioethics that began as an interdisciplinary study and which, through the research process, moved to being a transdisciplinary study in health ethics. They outline not only this transformation but also the strengths and difficulties of transdisciplinary research in the area of ethics.

    2011-01-01

    Interpersonal Psychotherapy (IPT), a time-limited, evidence-based treatment, has shown efficacy in treating major depressive disorder and other psychiatric conditions. Interpersonal Psychotherapy focuses on the patient's current life events and social and interpersonal functioning for understanding and treating symptoms. This case report demonstrates the novel use of IPT as treatment for posttraumatic stress disorder (PTSD). Preliminary evidence suggests IPT may relieve PTSD symptoms without focusing on exposure to trauma reminders. Thus IPT may offer an alternative for patients who refuse (or do not respond to) exposure-based approaches. Interpersonal Psychotherapy focuses on two problem areas that specifically affect patients with PTSD: interpersonal difficulties and affect dysregulation. This case report describes a pilot participant from a study comparing 14 weekly sessions of IPT to treatment with two other psychotherapies. We describe the session-by-session IPT protocol, illustrating how to formulate the case, help the patient identify and address problematic affects and interpersonal functioning, and to monitor treatment response.

    Russo Martin, Elaine

    2006-01-01

    Objectives: The objective of this study is to apply J. Richard Hackman's framework on team effectiveness to academic medical library settings. Methods: The study uses a qualitative, multiple case study design, employing interviews and focus groups to examine team effectiveness in three academic medical libraries. Another site was selected as a pilot to validate the research design, field procedures, and methods to be used with the cases. In all, three interviews and twelve focus groups, with approximately seventy-five participants, were conducted at the case study libraries. Findings: Hackman identified five conditions leading to team effectiveness and three outcomes dimensions that defined effectiveness. The participants in this study identified additional characteristics of effectiveness that focused on enhanced communication, leadership personality and behavior, and relationship building. The study also revealed an additional outcome dimension related to the evolution of teams. Conclusions: Introducing teams into an organization is not a trivial matter. Hackman's model of effectiveness has implications for designing successful library teams. PMID:16888659

  7. Deploying High Penetration Photovoltaic Systems: A Case Study

    SciTech Connect

    Coddington, M. H.; Baca, D.; Kroposki, B. D.; Basso, T.

    2011-01-01

    Photovoltaic (PV) system capacity penetration, or simply 'penetration,' is often defined as the rated power output of the aggregate PV systems on a distribution circuit segment divided by the peak load of that circuit segment. Industry experts agree that a single value defining high penetration is not universally applicable. However, it is generally agreed that a conservative value to designate high penetration is the condition when the ratio of aggregate PV systems ratings to peak load exceeds 15%. This case study illustrates the case of a distribution feeder which is able to accommodate a traditional capacity penetration level of 47%, and perhaps more. New maximum penetration levels need to be defined and verified and enhanced definitions for penetration on a distribution circuit need to be developed. The new penetration definitions and studies will help utility engineers, system developers, and regulatory agencies better agree what levels of PV deployment can be attained without jeopardizing the reliability and power quality of a circuit.

  8. Finding meaning in everyday life with dementia: A case study.

    PubMed

    Robertson, Jane M

    2014-07-01

    This paper presents a case study exploring an older woman's perspective on the quality of her life with dementia. The case study establishes the importance of coherence across the life course in understanding how she evaluates her changed situation in the present compared to the past. The metaphoric description of moving from 'up there' to 'down here' represents the perceived struggle to maintain a sense of worth despite a marginalised social position. Being able to define self and social identity in ways that preserve a sense of social status is important to find meaning in everyday life. Finding meaning involves looking backwards to sustain continuity with the past and looking forwards to maintain momentum and keep going. A narrative framework is valuable in showing that quality of life is a dimension of meaning associated with maintaining a sense of social worth.

    2015-01-01

    This case study is an example of applying narrative medicine as a useful tool for health professionals to manage an existential and complex scenario such as the suicide of a sibling. Some suicides are like baobab trees—these large and resilient trees grow deep roots for many years, only spreading their limbs above ground once they are firmly established. Like the baobab, when suicide or a suicide attempt occurs, suicidal ideations are well cultivated and have often already been repeatedly planted. Consequently, suicide is often difficult to prevent: once the death seed is planted, it is difficult to recreate life. Every year, more than 800,000 people die by suicide worldwide (1.4% of all deaths), which is approximately 1 person every 40 seconds. These unexpected deaths, predominantly occuring among young and middle-aged adults, have a continuing ripple effect and result in a huge economic, social, and psychological burden for individuals, families, communities, and countries. The complexity of suffering and pain experienced by suicidal individuals and their families, regardless of the success or failure of the suicidal act, is intensified by strong stigmas attached to traditional concepts of sin and eternal damnation. This unfortunate reality emerges in the narrative as a tragic family drama, which is permeated by deep feelings of helplessness. But suicide is preventable. Prevention requires 3 important factors: knowledge, public support, and creation of strategies to enact social change. Now is the time to act and make suicide prevention an imperative goal.

    A case-control study has been carried out to examine the occurrence of childhood cancer in relation to the proximity of overhead power lines to a child's home address at birth and to the calculated magnetic field at the address. The study included 374 cases diagnosed in the Yorkshire Health Region between 1970 and 1979, together with 588 matched controls. Magnetic-field strengths at the birth addresses due to the load currents of overhead power lines were calculated on the basis of line-network maps and load records. The results indicate no association between the occurrence of childhood malignancies and either the proximity or the magnetic fields of overhead lines, although the statistical power of the study was limited by the small numbers of children living close to overhead power lines.

    Background Several studies have suggested an association between periodontal disease and prematurity but this finding has not been consistently observed. Methods Case control study. Cases (n = 50) were women who had delivered after spontaneous preterm labor at <35 weeks gestation. Two groups of controls (n = 101) were recruited: women who were undelivered but at a preterm gestation and women who delivered at term. A standard, clinical, periodontal examination was performed and gingival crevicular fluid was obtained from standardized locations and tested for neutrophil elastase along with the bacterial enzymes gingipain and dipeptidylpeptidase. Data were analyzed with Fisher's exact tests, ANOVA and multivariate logistic regression. Results There was no difference in the proportion of sites with significant attachment loss (≥3 mm): Cases-3.2%, Controls-2.2% p = 0.21. The gingival crevicular fluid concentrations of elastase and gingipain were elevated in cases vs. controls 238.8 uU/ul vs. 159.6 uU/ul p = .007 and 2.70 uU/ul vs. 1.56 uU/ul p = .001. On multivariate analysis, the mean log concentration of elastase, but not of gingipain, remained a significant predictor of preterm labor p = .0.015. Conclusion We found no evidence that clinical periodontal disease is associated with spontaneous preterm birth. Elevated gingival crevicular fluid levels of elastase were associated with preterm birth but further research is needed before this can be assumed to be a causal relationship. PMID:16848912

    Albertazzi, Liliana; Poli, Roberto

    2014-01-01

    The paper presents color as a case study for the analysis of phenomena that pertain to several levels of reality and are typically framed by different sciences and disciplines. Color, in fact, is studied by physics, biology, phenomenology, and esthetics, among others. Our thesis is that color is a different entity for each level of reality, and that for this reason color generates different observables in the epistemologies of the different sciences. By analyzing color as a paradigmatic case of an entity naturally spreading over different levels of reality, the paper raises the question as to whether making explicit the usually implicit ontological assumptions embedded within the different observables exploited by the different sciences may eventually clarify some of the difficulties of developing a comprehensive theory of color.

    In this case study, a young women who has chronic verbal, emotional, and physical abuse and was exposed to repetitive adult acts of abuse as a child initially presented with Posttraumatic Stress Disorder (PTSD) marked by constriction and disconnection, which resulted in her feeling passive and tortured. As part of her occupational therapy intervention, based on the occupational adaptation, psychoanalytic, and recovery frames of reference, she was able to use her skills as a musician and lyricist to work through her trauma by performing heavy metal music. She used work to express emotions and tell and retell her story to audiences eager to hear her. Work helped her develop an identity that allowed her to be active in the world and reach out to others through her music. This case study focuses on the intervention - how music and occupation functioned as a foundation for relieving her PTSD.

    Background Childhood cancer was the leading cause of death among children aged 1-14 years for 2012 in Spain. Leukemia has the highest incidence, followed by tumors of the central nervous system (CNS) and lymphomas (Hodgkin lymphoma, HL, and Non-Hodgkin’s lymphoma, NHL). Spatial distribution of childhood cancer cases has been under concern with the aim of identifying potential risk factors. Objective The two objectives are to study overall spatial clustering and cluster detection of cases of the three main childhood cancer causes, looking to increase etiological knowledge. Methods We ran a case-control study. The cases were children aged 0 to 14 diagnosed with leukemia, lymphomas (HL and NHL) or CNS neoplasm in five Spanish regions for the period 1996-2011. As a control group, we used a sample from the Birth Registry matching every case by year of birth, autonomous region of residence and sex with six controls. We geocoded and validated the address of the cases and controls. For our two objectives we used two different methodologies. For the first, for overall spatial clustering detection, we used the differences of K functions from the spatial point patterns perspective proposed by Diggle and Chetwynd and the second, for cluster detection, we used the spatial scan statistic proposed by Kulldorff with a level for statistical significance of 0.05. Results We had 1062 cases of leukemia, 714 cases of CNS, 92 of HL and 246 of NHL. Accordingly we had 6 times the number of controls, 6372 controls for leukemia, 4284 controls for CNS, 552 controls for HL and 1476 controls for NHL. We found variations in the estimated empirical D(s) for the different regions and cancers, including some overall spatial clustering for specific regions and distances. We did not find statistically significant clusters. Conclusions The variations in the estimated empirical D(s) for the different regions and cancers could be partially explained by the differences in the spatial distribution of

    Cooper, Garry

    This article will focus on the evidence to support the treatment of a palliative patient who was diagnosed with cancer-related secondary lymphoedema. A case study approach has been adopted, which focuses on the anatomy and physiology of lymphoedema and how this is treated through an analysis of the treatment regimens. To establish the effectiveness of these treatment regimes, the use of objective and subjective tools will also be analysed to ascertain their importance within care. The findings of this case study and the supporting evidence indicate a positive correlation between the use of lymphoedema treatment methods in both limb volume reduction and quality-of-life outcomes. However, robust evidence is required to expand the importance of each treatment used in the area of lymphoedema management.

    Cysticercosis is a disease that occurs via the dissemination of the larvae form of the pork tapeworm Taenia solium to various organ systems, including the central nervous system. Sequelae may include seizures and neuropsychological impairment. The present case study involves a 45-year-old Caucasian female executive diagnosed with neurocysticercosis. Evaluation methods consisted of neuropsychological and electrophysiological assessment. Both neuropsychological evaluation and electrophysiological testing suggested right temporal and right parietal lobe dysfunction. Comparison of neuropsychological and quantitative electroencephalogram (QEEG) test results yielded high agreement in terms of site of lesion as documented by magnetic resonance imaging (MRI) and computed tomography scan (CT scan) findings. Neuropsychological findings are described in detail, as well as a description of subsequent neurocognitive rehabilitation. Serial assessment is delineated and compared with the baseline evaluation. This case study serves to underscore the clinical utility of neuropsychological assessment and neurocognitive rehabilitation in infectious disease consultations, specifically in neurocysticercosis.

    Embodied health movements work on the boundary between lay and expert knowledge. Consumer groups, depending on their goals, may increase or decrease pharmaceuticalization. This paper reports a small case study about the retrospective evaluation of a specific second line treatment for type 2 diabetes by an existing patient involvement group. The group is part of a research collaboration between academia and the health service in England, and shares some characteristics of embodied health movements. We used the case study to explore whether an institutionally funded non activist patient group can make a more balanced contribution to drug licensing decisions than that made by either access-oriented or injury-oriented consumer groups, without being co-opted by an institutional agenda. The questions we wished to address were how this group evaluated existing mechanisms for licensing drugs; how they balanced scientific and lay knowledge; how they made their decisions; and how they viewed their experiences as panel members. The five panel members were interviewed before and after the panel discussion in July 2013. They were critical of current licensing processes, and used their own embodied experiences of medicines to evaluate expert knowledge. Their decisions on the panel were informed either by a balancing of benefits and harms, or by trust in experts. The case study suggests that such a group may have the potential both to balance the pro-pharmaceuticalization impact of access-oriented groups and to influence forms of pharmaceutical governance.

  9. Psychopathology in the light of brain injury: a case study.

    PubMed

    Leftoff, S

    1983-02-01

    A case study of late onset psychopathology following brain injury is presented to illustrate the effects of cognitive and perceptual loss on personality functions. Based on Hughling Jackson's (1884/1958) notion of the duality of the symptom, we proposed a model of the development and process of psychopathology following brain injury, which views the development of the psychopathological behavior as a product of acquired cognitive and perceptual defects and ensuing compensatory strategies. For the present case study of paranoia, this involved defects in long-term memory, conceptual ability, and compensatory strategies of confabulation and self-referential orientation. Neuropsychological testing established defects in concept formation tasks including the Raven Progressive Matrices, the Leiter International Performance Scale, and the Wisconsin Card Sorting test, as well as long-term memory defects where cognitive reorganization was needed. The paranoid process was understood as a product of disordered conceptual ability in interpersonal situations, and a self-referential conceptual classification system, which took time, and changed social relations, to emerge. The implications of this model for psychotherapy with brain injury is elaborated in our case study, in which psychotherapeutic intervention included training on interpersonal hypothesis formation.

    Mixing is an important part of irreversible stratosphere troposphere exchange. Yet the mixing process is poorly understood. We present a case study of mixing in the vicinity of the subtropical jet, using airborne in situ and remote sensing data during SONEX mission. The case of intrusion of stratospheric air is identified using ozone profile curtains from DIAL LIDAR onboard DC-8. The thermal structure across the tropopause is mapped using temperature profiles from Microwave Temperature Profiler (MTP), together with the potential vorticity field based on the ECMWF data. Spatial extent of mixing between stratospheric and tropospheric air is examined using tracer relationships from in situ measurement onboard DC-8. Results show that mixing between stratospheric and tropospheric air involved air mass with ozone value up to ~400 ppbv. The case study also show that based on the tracer relationship alone, without the background information provided by the LIDAR data and MTP data, it is often difficult to conclude whether the observed mixing represent stratosphere to troposphere transport or troposphere to stratosphere transport. Results also show that using 2 PVU or 3.5 PVU contour as the tropopause in this case will likely underestimate the stratosphere to troposphere transport.

    2005-01-01

    Critical examination of the processes by which we as nurses judge and reach clinical decisions is important. It facilitates the maintenance and refinement of good standards of nursing care and the pinpointing of areas where improvement is needed. In turn this potentially could support broader validation of nurse expertise and contribute to emancipation of the nursing profession. As pure theory, clinical decision-making may appear abstract and alien to nurses struggling in 'the swampy lowlands' (Schon 1983) of the realities of practice. This paper explores some of the key concepts in decision-making theory by introducing, then integrating, them in a reflective case study. The case study, which examines a 'snapshot' of the patient and practitioner's journey, interwoven with theory surrounding clinical decision-making, may aid understanding and utility of concepts and theories in practice.

    Occupational therapy practitioners frequently identify opportunities for international practice. The World Health Organization and the World Federation of Occupational Therapists have encouraged occupational therapists to address transnational issues, social inclusion, and equal access to opportunities grounded in meaningful occupation (WFOT, 2012). This case study describes a partnership between two U.S. schools of occupational therapy and a Cuban community based pediatric clinic. It examines the dynamics that have sustained the partnership despite political, economic, and logistical barriers. The literature is scrutinized to show how this case study fits into other accounts of collaborative international partnerships. Particularly, it investigates structural and institutional conditions that shape international sustainable partnerships. In doing so, we answer the following questions: (1) Under which circumstances do international partnerships emerge and flourish? (2) What structural and institutional conditions shape international sustainable partnerships? And (3) How do partners perceive and experience the bilateral international partnership? It also discusses and illustrates the foundations and development of international partnerships that succeed. Through the use of a case study we illustrate the development of this partnership. Finally, we consider the next steps of this particular sustainable and collaborative international partnership.

  19. Treatment of a mild chronic case of ciguatera fish poisoning with intravenous mannitol, a case study.

    PubMed

    Mitchell, Gary

    2005-03-01

    This article describes a recent case of ciguatera poisoning treated with intravenous mannitol. Mannitol has been used with good effect in non-controlled studies in acutely severely poisoned patients, but is not described in the treatment of chronic or milder poisoning. Our patient was a 35-year-old Niuean man who had eaten a ciguatoxic fish two weeks previously. His symptoms were not severe but were very unpleasant and restricted his ability to work. He was given a single dose of mannitol (0.66g/kg) as an intravenous infusion over two hours. His symptoms dramatically improved within 24 hours, and within a few days he felt virtually back to his former self. He experienced no side effects to the mannitol. It is suggested that intravenous mannitol may prove to be a useful treatment for mild to moderate ciguatera poisoning, and for patients who present late for treatment.

    2012-04-01

    The decision to design and build a new aircraft is preceded by years of research and study. Different disciplines work together throughout the lifecycle to ensure not only a complete functional definition of the product, but also a complete industrialization, a marketing plan, a maintenance plan, etc. This case study focuses on the conceptual design phase. During this phase, the design solutions that will meet the functional and industrial requirements are defined, i.e.: the basic requirements of industrialization. During this phase, several alternatives are studied, and the most attractive in terms of performance and cost requirements is selected. As a result of the study of these alternatives, it is possible to define an early conceptual design of the assembly line and its basic parameters. The plant needs, long cycle jigs & tools or industrial means and human resources with the necessary skills can be determined in advance.

    Cape Queer is a case study that details how sexuality intersects with race, gender, and class in the development of the gay and lesbian resort community, Provincetown, Massachusetts. It asks scholars to pay closer attention to the ways in which methodologies and practices utilizing LGBT studies and queer theory can combine rather than separate to interrogate LGBT and queer histories, politics and communities. In the process, it assesses how the global mechanics of capitalism led to the local queering and eventually un-queering of a gentrified, white, gay and lesbian enclave.

    This paper presents a case study for an exhaust fan rotor made from elements assembled through bolted joints. For this design of the rotor and normal operating conditions the fan achieve the field of resonance, conducting to the failure of rotor bearing assembly, and finally of the entire fan. The finite element method (FEM) is used to study the stress, strain and natural frequencies of the fan rotor. The FEM analysis proves that a rotor with welded construction eliminates the disadvantage of the resonance phenomenon occurrence in the range of the normal operating speed.

    Case studies and case reports form an important and ever growing part of scientific and scholarly literature. The paper deals with the share and citation rate of these publication types on different fields of research. In general, evidence seems to support the opinion that an excessive number of such publications may negatively influence the impact factor of the journal. In the literature of scientometrics, case studies (at least the presence of the term "case study" in the titles of the papers) have a moderate share, but their citation rate is practically equal to that of other publication types.

    1986-11-01

    An autopsied case of jargon aphasia by multiple cerebral infarction was reported. A 75-year-old right-handed woman developed a Wernicke's aphasia with the first attack of cerebral infarction in the left hemisphere in July 1980. With the second attack of infarction in October 1980, she developed a neologistic and semantic jargon aphasia, in which her speech consisted of neologisms, literal paraphasias, empty phrases and so-called "misused words". CT-findings showed two low density areas; one was in the left hemisphere and the other in the posterior region of the right hemisphere. Her jargon aphasia persisted for about one year. In November 1981, she suffered a third attack of infarction and developed an apallic syndrome. Neuropathological examination confirmed that the lesion of the right hemisphere played a decisive role in the outbreak of jargon aphasia in this case.

    2011-01-01

    Accompanied with various opinions across cultures, truth telling is a major debate in bioethics. Many studies have focused on attitudes toward truth disclosure. We intend to review several relevant research studies, and discuss the issue through a clinical case consultation. It seems that while "the right to know" is emphasized in bioethics, in some cultural contexts, health professionals fear communicating bad news. The patients may not receive information directly, because it is believed that the truth may make the patient feel hopeless and unable to cope with the problem. Nevertheless, some believe that sharing information may strengthen a trusting relationship between patients and medical professionals. Extensive efforts are in process in some societies to make patient rights to know the truth as a natural part of medical practice. However, in some cases, the principles of respect for patient autonomy require us to accept patient's refusal to know the truth, with the provision that he assigns someone to receive information and make medical decisions on his behalf. In conclusion, it is suggested that healthcare professionals should not act on a unique presumption in all cases and they should explore what the real interest of patient is, in order to respect individual autonomy.

    2013-01-01

    Background: Gastroschisis, a birth defect characterized by herniated fetal abdominal wall, occurs more commonly in infants born to teenage and young mothers. Ischemia of the vascular vitelline vessels is the likely mechanism of pathogenesis. Given that chronic stress and violence against women are risk factors for cardiovascular disease we explored whether these may represent risk factors for gastroschisis, when they occur during pregnancy. A case-control study was conducted, with 15 incident cases of children born with gastroschisis in the Region of Murcia, Spain, from December 2007 to June 2013. Forty concurrent controls were recruited at gestation weeks 20–24 or post-partum. All mothers of cases and controls completed a comprehensive, in-person, ‘green sheet’ questionnaire on environmental exposures. Results: Mothers of children with gastroschisis were younger, smoked more cigarettes per week relative to controls, were exposed to higher amounts of illegal drugs, and suffered from domestic violence more frequently than the controls. Multivariable logistic regression analysis highlights periconceptional ‘gender-related violence’ (OR: 16.6, 95% CI 2.7 to 101.7) and younger maternal age (OR 1.1, 95% CI 1.0–1.3). Conclusions: Violence against pregnant women is associated with birth defects, and should be studied in more depth as a cause-effect teratogenic. Psychosocial risk factors, including gender-based violence, are important for insuring the health and safety of the pregnant mother and the fetus. PMID:24142184

    Introduction Dermatoses affecting palms and soles are among the most difficult of all dermatological therapeutic problems. Many previous studies have focused on the specific diseases of palmoplantar dermatoses. However, none of them have included a comprehensive study of palmoplantar dermatoses. Aims: To study the epidemiological aspects like age distribution, sex distribution, the dermatoses affecting the palms & soles and the frequency of involvement of palms, soles or both palms & soles, in patient with palmoplantar dermatoses. Materials and Methods This cross sectional study was conducted in the Department of Dermatology between October 2011 to September 2013. First 300 cases attending the department of dermatology primarily with complaints pertaining to palms and soles were enrolled in the study. After taking consent a detailed history and clinical examination pertaining to the aim of the study was recorded and analysed, which included inspection of morphology and distribution of lesions and palpation of any swelling. Direct microscopic examination of scrapings, wet mounted with 10% potassium hydroxide was done for cases with scaly lesions. Those who had a pustule, gram staining was done. Patch testing using Indian Standard Battery Series was done for those cases of eczema. A sample for biopsy was taken when diagnosis could not be arrived clinically, and subjected to histopathological examination. Results In our study of 300 patients with palmoplantar dermatoses, 164 were females and 136 were males, the ratio observed being 1.2:1. The peak incidence was found in the age group 21-30 years, with 41 females (25%) and 35 males (25.7%). Most frequently affected individuals in this study were housewives (30%). The most common five diseases of palmoplantar dermatoses were palmoplantar psoriasis (20.7%), moniliasis (19%), palmoplantar hyperhidrosis (7%), keratolysis exfoliativa (6%) and pitted keratolysis (6%). Majority of patients had involvement of both palms and

    Will the impact of baby boomers, as they age, be a bonanza or a bust for the healthcare system? A range of perspectives prevail, from increasing in-patient admissions capacity to accommodate the sheer numbers, to the creation of a variety of healthcare services and delivery channels that address their unique requirements. This case study presents a top 100, regional hospital's approach to this dilemma. The strategic marketing process using segmentation, targeting, and positioning (STP) was employed to guide the administration's planning and decision making.

    Medicine counterfeiting is a current problem that the whole pharmaceutical field has to deal with. In 2014, counterfeits entered the legitimate supply chain in Europe. Quick and efficient action had to be taken. The aim of this paper is to explain which analytical strategy was chosen to deal with six of the cases concerned and which criteria have to be considered to provide quick and thorough information about the counterfeits. The evaluation of the packaging was performed in a first step, based on a comparison with genuine samples and evaluation of manipulation signs. Chemical methods were then used, consisting of near infrared and infrared spectroscopy, capillary zone electrophoresis and ultraviolet-visible spectrophotometry, in order to authenticate the samples and provide the chemical composition of the confirmed counterfeits. Among the 20 samples analyzed, 17 were confirmed as counterfeits. The counterfeits were the results of the manipulation of genuine samples, and one contained totally counterfeited parts. Several manipulation signs were asserted, like the addition of glue on the boxes and the vials. Genuine stolen goods had been diluted with water, while for an isolated case, a different active ingredient had been introduced in a vial. The analytical data generated were further investigated from a forensic intelligence perspective. Links could be revealed between the analyzed counterfeits, together with some interesting information about the modus operandi of the counterfeiters. The study was performed on a limited number of cases, and therefore encourages chemical and packaging profiling of counterfeits at a bigger scale. Copyright © 2015 John Wiley & Sons, Ltd.

    Background Concussion, its recognition, diagnosis, and treatment is a growing public health issue. Massage practitioners who specialize in rehabilitation deal with a variety of injury cases that involve concussion, including those incurred by falls, motor vehicle incidents, and sports injuries. Purpose This case study presents a unique massage therapy approach to concussion trauma treatment. Participant Male 23-year-old intramural soccer player diagnosed with postconcussion syndrome resulting from a fall. Intervention Assessment and treatment were completed in two sessions of 45 minutes spaced two days apart. Massage therapy techniques were applied to injury areas by a Licensed Massage Practitioner. Results Using the Balance Error Scoring System (BESS) and self-report, the outcome measures showed diminished concussion symptoms and regained ease in range of motion in the cervical area. Conclusion Positive results for this case highlight the potential importance of massage therapy work to reduce headache, dizziness, and nausea in concussion recovery. In the presence of such outcomes, massage therapy may also have a supportive role in a person’s return to function after concussion. PMID:26082825

    2011-05-01

    The requirements engineering (RE) processes have become a key to conceptualising corporate-wide integrated solutions based on packaged enterprise resource planning (ERP) software. The RE literature has mainly focused on procuring the most suitable ERP package. Little is known about how an organisation exploits the chosen ERP RE model to frame the business application development. This article reports an exploratory case study of a key tenet of ERP RE adoption, namely that aligning business applications to the packaged RE model leads to integral practices and economic development. The case study analysed a series interrelated pilot projects developed for a business division of a large IT manufacturing and service company, using Oracle's appl1ication implementation method (AIM). The study indicated that AIM RE improved team collaboration and project management experience, but needed to make hidden assumptions explicit to support data visibility and integrity. Our study can direct researchers towards rigorous empirical evaluations of ERP RE adoption, collect experiences and lessons learned for practitioners, and help generate more effective and mature processes when exploiting ERP RE methods.

  17. Contaminant driven genetic erosion: a case study with Daphnia longispina.

    PubMed

    2012-05-01

    Natural populations exposed to pollutants are predicted to experience a loss of genetic diversity, especially through genetic drift, gene flow (emigration), and/or selection (as sensitive genotypes may be lost). In the present study, the authors discuss the use of selectable markers and neutral markers to evaluate a contaminant-driven loss of genetic diversity and possible implications of genetic erosion on populations' viability. Viability could be reduced by altering life history parameters, especially due to fitness costs associated with the acquisition of resistance and/or by compromising the resilience and adaptation to future environmental changes. This discussion aims at an integrated and critical analysis of this topic; it is illustrated by several independent studies (each with its own specific objectives) that were carried out at the same location with Daphnia longispina populations. To the best of the authors' knowledge, this is the most extensively documented case study on genetic erosion of a natural zooplankton population. Directional selection has been found to be a main factor of microevolution; therefore, genetic erosion was detected by monitoring suitable phenotypic markers. Genetic drift was found to be probably irrelevant or masked by other factors, especially gene flow. Although the acquisition of resistance apparently did not entail genetically determined fitness costs under uncontaminated conditions, the present case study suggests the possibility of a further loss of genotypes due to some negative linkages between the sensitivity to potential ulterior toxicants.

    2011-07-01

    Diet plays an important role in the etiology of certain cancers, but there is limited evidence with regard to the association between diet and risk of endometrial cancer. Few prospective studies have investigated meat intake as a potential determinant of endometrial cancer risk. The objective of this study was to examine the association between endometrial cancer risk and total meat, red meat, processed meat, fish, and poultry intake. We conducted a case-cohort analysis within the Canadian Study of Diet, Lifestyle, and Health, a prospective cohort of 73 909 adults (39 614 women). Participants were recruited from 1992 to 1999, predominantly from three Canadian universities. We conducted a linkage with the Ontario Cancer Registry for the years 1992-2007 for the female cohort members, who resided in Ontario at the time of enrollment (n=26 024), to yield data on cancer incidence. The analytic sample was comprised of 107 incident cases and 1830 subcohort members, the latter being an age-stratified sample of the full cohort. A nonsignificant increase in the risk of endometrial cancer was associated with increased consumption of red meat [hazard ratio (HR)=1.62, 95% confidence intervals (CI)=0.86-3.08, for high vs. low intake; P trend=0.13)], processed meat (HR=1.45, 95% CI=0.80-2.61, for high vs. low intake; P trend=0.058), and all meat combined (HR=1.50, 95% CI=0.78-2.89, for high vs. low intake; P trend=0.14). No clear patterns were noted for poultry or fish. The results of this study, although based on a limited number of cases, suggest that relatively high meat intake may be associated with increased risk of endometrial cancer.

    Nephrology nurses play a major role in every aspect of caring for patients on dialysis. It is always challenging to witness patients and families struggling through dialysis modality changes coupled with end-of-life decisions. Open discussions and care provided by an interdisciplinary team approach provides the foundational structure for quality care necessary for this population. In the case of Mr. T., a dialysis modality change was a necessary change in his life. The FNP PCP played a significant role in coordinating his care to achieve the desired outcomes and ensure there was a coordinated team approach.

    2011-02-01

    Results of case-control studies of mobile phone use and acoustic neuroma have been inconsistent. We conducted a case-case study of mobile phone use and acoustic neuroma using a self-administered postal questionnaire. A total of 1589 cases identified in 22 hospitals throughout Japan were invited to participate, and 787 cases (51%) actually participated. Associations between laterality of mobile phone use prior to the reference dates (1 and 5 years before diagnosis) and tumor location were analyzed. The overall risk ratio was 1.08 (95% confidence interval (CI), 0.93-1.28) for regular mobile phone use until 1 year before diagnosis and 1.14 (95% CI, 0.96-1.40) for regular mobile phone use until 5 years before diagnosis. A significantly increased risk was identified for mobile phone use for >20 min/day on average, with risk ratios of 2.74 at 1 year before diagnosis, and 3.08 at 5 years before diagnosis. Cases with ipsilateral combination of tumor location and more frequently used ear were found to have tumors with smaller diameters, suggesting an effect of detection bias. Furthermore, analysis of the distribution of left and right tumors suggested an effect of tumor-side-related recall bias for recall of mobile phone use at 5 years before diagnosis. The increased risk identified for mobile phone users with average call duration >20 min/day should be interpreted with caution, taking into account the possibilities of detection and recall biases. However, we could not conclude that the increased risk was entirely explicable by these biases, leaving open the possibility that mobile phone use increased the risk of acoustic neuroma.

    2002-01-01

    Hand hygiene of healthcare workers is frequently poor despite the efforts of infection control teams to promote hand decontamination as the most important method to prevent transmission of hospital-acquired infections. In this case study, we describe how principles of societal marketing were applied to improve hand hygiene. Pre-marketing analysis of strengths, weaknesses, opportunities and threats to implementation; attention to product, price, promotion and placement; and post-marketing 'customer' surveys were the essential components of the marketing strategy and its implementation. Placement of an alcohol-based gel decontaminant (Spirigel) at the bedside of every patient was widely welcomed in the hospital, and has played a major role in improving hand hygiene of healthcare workers. In the twelve months following the implementation, the decontaminant was used at least 440,000 times. The cost of purchasing the decontaminant was approximately 5000 pounds sterling. Following the introduction of Spirigel, there was a consistent reduction in the proportion of hospital-acquired methicillin-resistant Staphylococcus aureus (MRSA) in each of the quarters of 2000-2001 compared with 1999-2000. In the period 1999-2000, nearly 50% of the MRSA were hospital acquired compared with 39% in 2000-2001. Similarly, the average incidence of Clostridium difficile associated diarrhoea (CDAD) decreased in each of the quarters in 2000-2001 following the introduction of Spirigel. During this period, there was an average incidence of 9.5 cases of CDAD/1000 admissions compared with 11.5 cases of CDAD/1000 admissions in 1999-2000. This represents a 17.4% reduction in the incidence of CDAD. However, this reduction was not statistically significant (P=0.2). Our case study demonstrates that principles of societal marketing methods can be used effectively to promote and sustain hand hygiene in hospitals. Improvement in hand hygiene will lead to considerable reduction in hospital

  2. Implementation of case studies in undergraduate didactic nursing courses: a qualitative study

    PubMed Central

    2013-01-01

    Background The implementation of unfolding scenario-based case studies in the didactic classroom is associated with learner-centered education. The utilization of learner-centered pedagogies, such as case studies, removes the focus from the instructor and instead places it on the student. Learner-centered pedagogies are believed to improve students’ levels of cognition. The purpose of this study was to examine how nurse educators are implementing the pedagogies of case studies in their undergraduate didactic courses. The goal was to examine, document, report, and, ultimately, implement the strategies. Methods Purposeful sampling was utilized in this qualitative, multisite-designed study. For each of the four participants, three separate site visits were completed. Observations and post-observational interviews took place at each site visit. Transcribed data from interviews, observations, and course documents were imported into the computer program Nvivo8. Repetitive comparative analysis was utilized to complete the data coding process. Results The guiding research question of this study sought to investigate the implementation strategies of case studies in didactic nursing courses. The implementation of case studies by the participants reflected two primary patterns: Formal Implementation (FI) and Informal Implementation (II) of case studies. The FI of case studies was further divided into two subcategories: Formal Implementation of case studies used Inside the Classroom setting (FIIC) and Formal Implementation of cases studies used Outside of the Classroom (FIOC). Conclusion Results of this investigation have led to an increased understanding of implementation strategies of unfolding scenario-based case studies in undergraduate nursing didactic courses. Data collected were rich in the description of specific methodologies for utilization of case studies and may serve as a resource for faculty in development of creative strategies to enhance the didactic

    An 11 months 22 days old girl presented with a history of watery diarrhoea since birth, failure to thrive, and developmental delay. Her diagnosis was congenital chloride diarrhoea (CCD) with raised level of chloride (>90 mmol/L) in stool in the absence of cystic fibrosis. Management of CCD included replacement of NaCl, KCl, and correction of dehydration. Diarrhoea of the patient was resolved with Captopril, which was initially provided to the patient for managing heart failure. To our knowledge, this is the first reported case of CCD that shows the beneficial effect of Captopril. Therefore, we suggest that further study is warranted as to the potential for Captopril as additional option in the treatment for CCD. We present this case report with the informed consent of the patient's guardian.

    Understanding faculty motivations for and barriers to change is an important component of facilitating instructional reform efforts to improve student learning. This case study describes the process of adoption of learner-centered instructional strategies by an astronomy faculty member, Ken, as viewed through the lens of conceptual change. Specifically, we applied the Cognitive Reconstruction of Knowledge Model (CRKM) to understand why Ken was willing to change his instructional strategies, what barriers to and supports for change existed, and how he and his students were impacted by this change. Ken's statements and actions represented characteristics consistent with the CRKM. Notably, dissatisfaction, considered the primary motivator in many conceptual change models, was not of high importance in this case. Upon implementing learner-centered strategies, Ken's students performed better on a measure of knowledge about stellar properties, which served to reinforce his motivation to continue with learner-centered methods.

    A total of 399 patients with multiple myeloma and an equal number of match controls were interviewed about factors possibly related to the causes of their disease. Factors studied included occupation, chemical exposure, radiation exposure, prior diseases, immunizations, chronic infections and markers for defects in immune regulation. A strong risk associated with agriculture/food processing was observed (RR = 1.8, P = 0.002). The risk could not be restricted to those exposed to animals or meat products, or those exposed to pesticides. Significant excesses were also noted for reported exposures to chemicals and gases/fumes, but no specific agent or group of agents could be identified. Cases had fewer tonsillectomies above the age of 10 (P = 0.01). A large excess of shingles (herpes zoster) was observed in cases (P less than 0.001), but most of the excess cases occurred within 10 years of diagnosis, suggesting this was a preclinical manifestation of disease rather than a cause of it.

    When impacting on a solid, heavy cluster atoms are stopped less then equi-velocity atoms. Using molecular-dynamics simulation, we study this so-called clearing-the-way effect systematically for the exemplary case of Au n clusters ( n = 1-402) bombarding a solid Ar target with energies in the range of Eat = 10-1000 eV/atom. We find that cluster stopping is reduced by a factor n- β with respect to that of equi-velocity atoms. The exponent β decreases from 0.46 at Eat = 10 eV/atom to 0.17 at Eat = 1000 eV/atom.

    An efficient, integrated health services delivery enterprise requires the ability to coordinate service delivery across the provider network and avoid duplication of services. It must be able to associate relevant clinical information with patients regardless of which facility delivered the services. There are significant challenges in collecting, organizing, and extracting value from data collected in the course of providing healthcare. This paper follows a large urban public healthcare enterprise in its attempts to address some of these challenges. Using a case-study methodology, the paper shows how information technology (IT) can help a healthcare organization derive improved information and generate knowledge from data stored in disjoint systems.

    Lower cancer risk in Parkinson's disease (PD) patients compared to the general population has been reported. However, most of the studies were based on death certificates. We designed a case-control study to estimate the association of tumor preceding PD onset and PD. PD patients were matched by age and gender to PD-free individuals, randomly selected from the municipalities of residence of cases. Occurrence of tumors preceding PD onset was assessed through a structured questionnaire. Neoplasms were categorized as benign, malignant, or of uncertain classification, and endocrine-related or not. Odds ratios (OR) were calculated using conditional logistic regression and adjusted for tumor categories and risk factors. We included 222 PD patients. Frequency of cancer was 6.8% for cases, 12.6% for controls. PD patients had a decreased risk for neoplasms (adjusted OR, 0.4; 95% confidence interval [CI], 0.2-0.7). Risk was reduced only for women (adjusted OR, 0.3; 95% CI, 0.1-0.7). PD patients had a decreased risk both for malignant (adjusted OR, 0.6; 95% CI, 0.1-2.5) and nonmalignant neoplasms (adjusted OR, 0.3; 95% CI, 0.1-0.7). Still, risk was decreased for endocrine-related tumors (adjusted OR, 0.3; 95% CI, 0.1-0.9) and non-endocrine-related tumors (adjusted OR, 0.4; 95% CI, 0.1-0.9). Our study confirms the inverse association between PD and neoplasms reported in previous epidemiologic studies.

    Depression is a complex disorder with heterogeneous clinical anomalies whose neurobiological understanding still remains unclear. Medications have been implicated as potential causes of depression but for many of them, data are controversial. The present study aims to investigate association bet ween drugs and reports of depression. We used the case/non case method in the French pharmacovigilance database (FPVD) to identify drugs associated with depression. Cases were reports of depression in the FPVD between January 2007 and December 2011. Non cases were all other reports during the same period. Data were expressed as reporting odds ratio (ROR) with their 95% confidence interval. Of the 114,692 reports recorded in the FPVD during the studied period, we identified 474 cases of depression. For the majority of the patients, they were considered as "non serious" (56%) and evolution was favorable (64%). Significant RORs were found for antiepileptics (topiramate, levetiracetam), anti-infective and especially anti-retroviral drugs (efavirenz, emtricitabine, tenofovir, etravirine, raltegravir), interferons and other agents including isotretinoin, methylphenidate, sodium oxybate, varenicline, montelukast, flunarizine, adalimumab, anastrozole. Taking into account the limits of the methodology, the present study described associations with mainly expected drugs belonging to various therapeutic classes but it also found a signal with some anti-retrovirals. On the contrary, we did not find some assumed associations like cardiovascular medications, antimalarial. For most of the drugs, one or more mechanisms were found to explain these depressogenic effects on the basis of animal and human literature. Even if such associations need to be confirmed by further prospective studies, cautions are necessary for many drugs to early detect depressive symptoms.

    OBJECTIVES: Associations between occupational exposures and the occurrence of cutaneous melanoma were examined as part of a large population based case-control study of 19 cancer sites. METHODS: Cases were men aged 35 to 70 years old, resident in Montreal, Canada, with a new histologically confirmed cutaneous melanoma (n = 103). There were two control groups, a randomly selected population control group (n = 533), and a cancer control group (n = 533) randomly selected from among subjects with other types of cancer in the large study. Odds ratios for the occurrence of melanoma were calculated for each exposure circumstance for which there were more than four exposed cases (85 substances, 13 occupations, and 20 industries) adjusting for age, ethnicity, and number of years of schooling. RESULTS: Significantly increased risk of melanoma was found for exposure to four substances (fabric dust, plastic dust, trichloroethylene, and a group containing paints used on surfaces other than metal and varnishes used on surfaces other than wood), three occupations (warehouse clerks, salesmen, and miners and quarrymen), and two industries (clothing and non-metallic mineral products). CONCLUSIONS: Most of the occupational circumstances examined were not associated with melanoma, nor is there any strong evidence from previous research that any of those are risk factors. For the few occupational circumstances which were associated in our data with melanoma, the statistical evidence was weak, and there is little or no supporting evidence in the scientific literature. On the whole, there is no persuasive evidence of occupational risk factors for melanoma, but the studies have been too small or have involved too much misclassification of exposure for this conclusion to be definitive.

    This case study provides a discussion of the diagnosis, management and comprehensive plan of care for empyema in children for the advanced practice registered nurse (APRN) working in primary care. The incidence of complicated pneumonias including those progressing to empyema is on the rise among pediatric patients. The ambiguous signs and symptoms of complicated pneumonias create a challenge for the provider when developing an accurate diagnosis and plan of care. Pediatric nurse practitioners must be cognizant of the increased incidence of complicated pneumonias and manage their patients accordingly. If left untreated, empyema may result in severe pulmonary complications.

    The joint commission recognizes effective communication among caregivers as an important factor for ensuring patient safety, especially at times when the patient's care is handed off from one caregiver or service to another. This case study reviews the course of treatment for one patient throughout the perioperative continuum, including the postoperative unit where a pre-arrest situation developed. A workshop using Bloom's Taxonomy of Educational Objectives enabled staff members to more clearly understand the patient's situation. It also allowed the participants to gain an increased understanding of significant data and has been strategic in preventing patient complications.

    Denmark is widely regarded as a leading country in terms of eHealth integration and healthcare delivery services. The push for eHealth adoption over that past 20 years in the Danish health sector has led to the deployment of multiple eHealth technologies. However, in reality the Danish healthcare suffers from eHealth system fragmentation which has led to eHealth's inability to reach full potential in delivering quality healthcare service. This paper will presents a case study of the current state of eHealth in the Danish healthcare system and discuss the current challenges the country is facing today.

    A variety of tomographic techniques that have been applied to multiphase flows are described. The methods discussed include electrical impedance tomography (EIT), magnetic resonance imaging (MRI), positron emission tomography (PET), gamma-densitometry tomography (GDT), radiative particle tracking (RDT), X-ray imaging, and acoustic tomography. Also presented is a case study in which measurements were made with EIT and GDT in two-phase flows. Both solid-liquid and gas-liquid flows were examined. EIT and GDT were applied independently to predict mean and spatially resolved phase volume fractions. The results from the two systems compared well.

    This paper presents the findings of a case study dealing mainly with the effects of two divergent leadership styles on the productivity of a planning organization. Changes in various kinds of participation in the agency's activities--an important side effect--are also linked to the two leadership patterns. The agency studied, a private health and welfare council in a medium-sized American city, varied considerably in its output of planning activities and decision making depending on whether it had a participative or a directive leader. The results indicated that there was a trade-off between such highly revered social values as leadership and the extent of participation by staff, board members, and local agency administrators. Implications focus on ways to achieve diversity in communication style among managers and the role of productivity measures in determining the overall effectiveness of planning agencies.

    This article examines the creation of a network of diverse religious leadership in a Midwest suburb where the intersection of religion and national pride fomented a community-wide conflict. Activated during a heated controversy over displaying a Christmas tree in a public school, the Network became a laboratory for testing viable strategies for community healing. The case of a Jewish student suspended for fighting when taunted for not singing Christmas Carols became a catalyst for debating what is religious, what is secular, and what is culturally American. The interaction of the key players is noted; educators, religious leaders, students and their families, particularly the mothers who regularly interacted across religious boundaries. The article describes the Network's experiment with deploying resources that accommodated diverse experiences of religion and patriotism, historically and culturally, within an American context.

    This paper presents a case study of air enrichment in an industrial rotary kiln type incineration unit. The study is based on mass and energy balances, considering the combustion reaction of a mixture composed by the residue and the auxiliary fuel with air enriched with oxygen. The steps are shown for the primary chamber (rotary kiln) and secondary chamber (afterburner). The residence times in the primary and secondary chamber are 2.0 and 3.2 sec, respectively. The pressure is atmospheric in both chambers. Based on constant chamber gas residence time and gas temperature, it is shown that the residue input rates can be increased by one order of magnitude as air is substituted by pure oxygen. As the residue consumption rate in the rotary kiln is also dependent on residue physical characteristics (mainly size), the study was also carried out for different percentages of oxygen in the oxidizer gas.

    This narrative case study examined the relationship between teacher identity and elementary science teaching. Teacher identity was described using a modification of Gee's framework incorporating three perspectives: the teachers' self-described identity, the researchers' view of teacher identity, and the students' views of teacher identity. Over the course of one school year, we studied one class of second-grade students receiving science instruction from three different teachers. We found that each teacher had unique identity characteristics. Further, the three perspectives of teacher identity were sometimes in conflict with one another within individual teachers, emphasizing the importance of incorporating multiple perspectives in order to give a complete description of teacher identity. This study has meaningful implications for understanding the ways in which students' perspectives can enrich our understanding of teacher identity.

    The objective of the study was to characterize the signalment, clinicopathologic data, and diagnostic imaging of cats with urate urolithiasis, as well as the salts of uric acid present in the uroliths. A retrospective analysis of feline urate uroliths submitted to the GV Ling Urinary Stone Analysis Laboratory between 2000 and 2008 was included. From these data, records were assimilated from referring veterinarians (143); furthermore, all recorded cases from within the William R Pritchard Veterinary Medical Teaching Hospital (16) were included. Median values for the complete blood count and chemistry panels available were within the reference intervals, when provided, with only a few outliers present. Of all cases evaluated, seven had a portosystemic shunt (PSS). Cats with urate uroliths and a PSS were younger than cats without a PSS (2 years vs 7 years). The pathogenesis of urate uroliths in cats is poorly understood. Most cats were not completely evaluated for a PSS, however, clinicopathologic parameters indicating hepatic dysfunction were seldom noted; more sensitive diagnostics such as serum bile acids were rarely performed to confirm or negate the presence of a shunt. Studies are warranted to evaluate pathogenesis of urate uroliths to tailor proper management and breeding strategies.

    Gliomatosis peritonei, a rare condition often associated with immature ovarian teratoma, is characterized by the presence of mature glial tissue in the peritoneum. We retrospectively evaluated 21 patients with gliomatosis peritonei and studied their clinicopathologic features and immunophenotype. The patients’ ages ranged from 5 to 42 years (median, 19 years). Their primary ovarian tumors consisted of immature teratoma (n = 14), mixed germ cell tumors (n = 6), and mature teratoma with a carcinoid tumor (n = 1). Gliomatosis peritonei was diagnosed at the same time as primary ovarian neoplasm in 16 patients and secondary surgery in 5 patients. Also, 11 of 21 patients had metastatic immature teratoma (n = 4), metastatic mature teratoma (n = 2), or both (n = 5). One patient developed glioma arising from gliomatosis peritonei. Seventeen patients had follow-up information and were alive with no evidence of disease (n = 13), alive with disease (n = 3), or alive with an unknown disease status (n = 1). The follow-up durations ranged from 1 to 229 months (mean, 49 months; median, 23 months). Immunohistochemistry results demonstrated that SOX2 was expressed in all cases of gliomatosis peritonei and glioma with tissue available (9 of 9 cases), whereas OCT4 and NANOG were negative in all cases with available tissue (8 of 8 cases). In conclusion, both gliomatosis peritonei and glioma arising from it show a SOX2+/OCT4−/NANOG− immunophenotype. These findings demonstrated that gliomatosis peritonei is associated with favorable prognosis, although it is important to rule out potentially associated immature teratoma and maligant transformation. SOX2 may play an important role in the development of gliomatosis peritonei. PMID:26564007

We use the case study as a resource in which we collect clinical data and did interviews with eight of fourteen nurses, who have been our subject-object. According to the nurses, clients are isolated from the world living in a world without hunger and mirrors reflecting a body always above the "ideal weight", they were lonely people, personnel who have lost their shine, sending signals that could extinguish their lives at any time. In the study, was possible to identify the manner in which nurses interacted and perceived customers and, as a result, we elucidate a peculiar practice in nursing.

Additional class emphasis is on evidence-based searching and journal article evaluation and presentation. The class objectives ensure that students are comfortable with mobile devices and collaboration tools. Over the eight-year history of the course, student acceptance of the mobile devices used diminished as the devices aged, necessitating the evaluation and selection of new technologies. Collaboration tools and mobile applications employed in the course evolved to accommodate curriculum changes.

    Laparoscopic cholecystectomy has become the standard procedure for the surgical management of cholelithiasis. Compared with open cholecystectomy, this procedure offers shorter hospital stays, shorter recovery time, better cosmetic results, and an overall reduction in health care cost for the patient. As the number of cardiac patients having elective laparoscopic cholecystectomy increases, it is important for the postanesthesia nurse to understand the postoperative assessment and nursing interventions these patients require. Congestive heart failure and acute pulmonary edema are two potential complications resulting from insufflation of the abdomen and intraoperative fluids. This case study of a cardiac patient undergoing laparoscopic cholecystectomy demonstrates important postanesthesia assessment parameters.

    2015-06-25

    The history of histology indicates that there have been significant changes in the techniques used for histological staining through chemical, molecular biology assays and immunological techniques, collectively referred to as histochemistry. Early histologists used the readily available chemicals to prepare tissues for microscopic studies; these laboratory chemicals were potassium dichromate, alcohol and the mercuric chloride to harden cellular tissues. Staining techniques used were carmine, silver nitrate, Giemsa, Trichrome Stains, Gram Stain and Hematoxylin among others. The purpose of this research was to assess past and current literature reviews, as well as case studies, with the aim of informing ways in which histological stains have been improved in the modern age. Results from the literature review has indicated that there has been an improvement in histopathology and histotechnology in stains used. There has been a rising need for efficient, accurate and less complex staining procedures. Many stain procedures are still in use today, and many others have been replaced with new immunostaining, molecular, non-culture and other advanced staining techniques. Some staining methods have been abandoned because the chemicals required have been medically proven to be toxic. The case studies indicated that in modern histology a combination of different stain techniques are used to enhance the effectiveness of the staining process. Currently, improved histological stains, have been modified and combined with other stains to improve their effectiveness.

    Building energy audit examines the ways actual energy consumption is currently used in the facility, in the case of a completed and occupied building and identifies some alternatives to reduce current energy usage. Implementation of energy audit are practically used to analyze energy consumption pattern, monitoring on how the energy used varies with time in the building, how the system element interrelate, and study the effect of external environment towards building. In this case study, a preliminary energy audit is focusing on Air-Conditioning & Mechanical Ventilation (ACMV) system which reportedly consumed 40% of the total energy consumption in typical building. It is also the main system that provides comfortable and healthy environment for the occupants. The main purpose of this study is to evaluate the current ACMV system performance, energy optimization and identifying the energy waste on UTeM's academic building. To attain this, the preliminary data is collected and then analyzed. Based on the data, economic analysis will be determined before cost-saving methods are being proposed.

  10. Landfill mining: Case study of a successful metals recovery project.

    2015-11-01

    Worldwide, the generation of municipal solid waste (MSW) is increasing and landfills continue to be the dominant method for managing solid waste. Because of inadequate diversion of reusable and recoverable materials, MSW landfills continue to receive significant quantities of recyclable materials, especially metals. The economic value of landfilled metals is significant, fostering interest worldwide in recovering the landfilled metals through mining. However, economically viable landfill mining for metals has been elusive due to multiple barriers including technological challenges and high costs of processing waste. The objective of this article is to present a case study of an economically successful landfill mining operation specifically to recover metals. The mining operation was at an ashfill, which serves a MSW waste-to-energy facility. Landfill mining operations began in November 2011. Between December 2011 and March 2015, 34,352 Mt of ferrous and non-ferrous metals were recovered and shipped for recycling, which consisted of metals >125 mm (5.2%), 50-125 mm (85.9%), <50mm (3.4%), zorba (4.6%), and mixed products (0.8%). The conservative estimated value of the recovered metal was $7.42 million. Mining also increased the landfill's airspace by 10,194 m(3) extending the life of the ashfill with an estimated economic value of $267,000. The estimated per-Mt cost for the extraction of metal was $158. This case study demonstrates that ashfills can be profitably mined for metals without financial support from government. Although there are comparatively few ashfills, the results and experience obtained from this case study can help foster further research into the potential recovery of metals from raw, landfilled MSW.

    Background Leptospira can be found in soil. However, it is unclear whether occupational exposure to soil may represent a risk for Leptospira infection in humans. Therefore, we sought to determine the association of Leptospira IgG seroprevalence with the occupation of gardener, and to determine the epidemiological characteristics of gardeners associated with Leptospira exposure. Methods We performed a case-control study in 168 gardeners and 168 age- and gender-matched control subjects without gardening occupation in Durango City, Mexico. The seroprevalence of anti-Leptospira IgG antibodies in cases and controls was determined using an enzyme immunoassay. Bivariate and multivariate analyses were used to assess the association of Leptospira exposure and the characteristics of the gardeners. Results Anti-Leptospira IgG antibodies were found in 10 (6%) of 168 gardeners and in 15 (8.9%) of 168 control subjects (odds ratio (OR): 0.64; 95% confidence interval (CI): 0.28 - 1.48; P = 0.40). Multivariate analysis showed that Leptospira seropositivity was positively associated with female gender (OR: 5.82; 95% CI: 1.11 - 30.46; P = 0.03), and negatively associated with eating while working (OR: 0.21; 95% CI: 0.05 - 0.87; P = 0.03). In addition, multivariate analysis showed that high anti-Leptospira levels were associated with consumption of boar meat (OR: 28.00; 95% CI: 1.20 - 648.80; P = 0.03). Conclusions This is the first case-control study of Leptospira exposure in gardeners. Results do not support an association of Leptospira exposure with the occupation of gardener. However, further studies to confirm the lack of this association are needed. The potential role of consumption of boar meat in Leptospira infection deserves further investigation. PMID:26668679

    Pregnancy after organ transplantation is becoming relatively common. We present the case of a heart transplant recipient who gave birth to a second child. Despite the fact that the transplanted heart seems to adapt well to the changes caused by pregnancy, gestation in patients after heart transplantation may be complicated by hypertension, pre-eclampsia, or preterm labor. In this article, we consider the issues of preterm uterine contractions, anemia, thrombocytopenia, and several other complications in pregnant patients with transplanted hearts. We also present current opinions regarding the use of glucocorticoids as a form of preventing breathing disorders in neonates as well as breast-feeding by mothers receiving immunosuppressive agents. Pregnancies in heart transplant recipients should be considered high-risk. A second successful delivery of a healthy child remains a challenge for such patients and their doctors. PMID:26336446

  13. The effects of macroglossia on speech: a case study.

    This article presents a case study of speech production in a 14-year-old Amharic-speaking boy. The boy had developed secondary macroglossia, related to a disturbance of growth hormones, following a history of normal speech development. Perceptual analysis combined with acoustic analysis and static palatography is used to investigate the specific articulatory compensations arising from the macroglossia. The subset of sounds chosen for study were the denti-alveolar and alveolar plosives, fricatives, ejectives, nasal, lateral and trill produced in single words, as well as in short phrases. The phonetic analysis revealed both spatial and temporal atypicalities in the realisations of the sounds in question. Speaking rate was slow relative to his peer's speech and attempts to increase speech rate resulted in dysfluent speech. Given the phonological system of Amharic, however, the atypical segmental realisations, while reducing both the intelligibility and acceptability of the participant's speech production, did not result in loss of phonological contrasts.

  14. Energy portfolio of Iran: A case study of solar desalination

    NASA Astrophysics Data System (ADS)

    Besharati, Adib

    Energy plays a very important role in the economic development of a country such as Iran where industrial progress and higher living standards increase demand for energy. Iran is one of the countries in the world that simultaneously produces and consumes large amounts of energy. Because of its geographic latitude and weather conditions, Iran has the potential to develop and use of both fossil and renewable energy sources. In South Iran, there are huge oil and gas resources, and at the same time high potential of solar radiation. However, at the present large-scale utilization, solar energy is prohibitively expensive for Iran. Therefore, this study investigates an economical way to utilize solar energy in a meaningful way for Iran. One of the possible uses of solar energy that is both economical and technically feasible is desalination of water using solar energy. People in South Iran live in different areas with relatively low population density. One of the critical problems in those areas is a lack of clean drinking water. As a result, there is an urgent need to investigate ways to produce clean water from the saltwater. Therefore, the present study conducts a case study of solar desalination in south Iran using solar. Different desalination methods, such as humidification dehumidification by using a solar collector, and reverse osmosis, are discussed. In the case study, a prototype desalination plant was considered and both technical and economic aspects of the plant were investigated in details. The results showed higher productivity of drinking water in reverse osmosis method for south Iran.

    Bofutsushosan, a herbal (traditional Kampo) medicine, is administered to obese patients in North-East Asia. Bofutsushosan has been reported to exert various anti-obesity effects by stimulating the adipose tissue. The present study describes the case of a patient who developed a severe pulmonary injury that was potentially associated with bofutsushosan therapy. A 52-year-old woman was admitted to Mito Medical Center, University of Tsukuba, Mito Kyodo General Hospital (Mito, Japan) due to progressive dyspnea. Two months previously, bofutsushosan had been newly prescribed for her obesity. Bilateral ground-glass opacities and progressive respiratory deterioration suggested respiratory failure due to a therapeutic agent-induced lung injury. With discontinuation of bofutsushosan and the administration of a corticosteroid, an improvement in her respiratory condition was achieved, although sequelae remained in certain areas of the lungs. Resumption of other therapeutic agents did not reinduce the lung injury. Therefore, a diagnosis of bofutsushosan-induced lung injury was made. Although bofutsushosan-induced lung injury is particularly rare, clinicians should consider it when bofutsushosan is used. PMID:28101346

    2010-02-01

    Purpose: We completed an implementation of pencil-beam scanning (PBS), a technology whereby a focused beam of protons, of variable intensity and energy, is scanned over a plane perpendicular to the beam axis and in depth. The aim of radiotherapy is to improve the target to healthy tissue dose differential. We illustrate how PBS achieves this aim in a patient with a bulky tumor. Methods and Materials: Our first deployment of PBS uses 'broad' pencil-beams ranging from 20 to 35 mm (full-width-half-maximum) over the range interval from 32 to 7 g/cm{sup 2}. Such beam-brushes offer a unique opportunity for treating bulky tumors. We present a case study of a large (4,295 cc clinical target volume) retroperitoneal sarcoma treated to 50.4 Gy relative biological effectiveness (RBE) (presurgery) using a course of photons and protons to the clinical target volume and a course of protons to the gross target volume. Results: We describe our system and present the dosimetry for all courses and provide an interdosimetric comparison. Discussion: The use of PBS for bulky targets reduces the complexity of treatment planning and delivery compared with collimated proton fields. In addition, PBS obviates, especially for cases as presented here, the significant cost incurred in the construction of field-specific hardware. PBS offers improved dose distributions, reduced treatment time, and reduced cost of treatment.

  20. Self-Injurious Behavior in Prison: A Case Study.

    PubMed

    Smith, Hayden

    2016-02-01

    The practice of self-injurious behaviors (SIBs) within corrections disproportionately consumes resources and negatively impacts staff. To date, the majority of empirical studies on the topic have relied upon quantitative methodologies that fail to include the perspective of the actual offender who is engaging in self-injury, thus reinforcing mischaracterizations and confusion. In response, this manuscript features a case study of an offender currently housed in a maximum security prison who routinely engages in self-injury. Findings are presented along the tripartite themes of family background, suicidality, and SIB. Policy implications include supporting a systematic reorientation toward therapeutic responses in lieu of the current punitive responses that may in fact be iatrogenic.

    This is a clinical case study of a 45-year-old, Caucasian male, active duty military officer. It demonstrates the short-term efficacy of habit-reversal training on the treatment of trichotillomania (TTM) in three 50-minute sessions, with concomitant, but unanticipated decreases in post-traumatic stress disorder (PTSD) symptoms and emotional distress as measured by the PTSD Checklist, Form PCL-M and OQ-45, respectively. This study discusses the benefits and limitations of such a short treatment for comorbid TTM and PTSD, while positing the relationship between the two disorders. Finally, it lends support for the classification of TTM as an anxiety disorder rather than an impulse-control disorder.

    The recently published report of the Carnegie Foundation's National Study of Nursing Education points out significant problems with classroom teaching in schools of nursing. This article suggests Palmer's idea of the subject-centered classroom as a way to transform nursing school classrooms into collaborative learning communities. For Palmer, the subject is the big idea of nursing practice-the nurse-patient/client/family/community relationship-that should take the lead in stimulating inquiry and discussion. The article goes on to describe how teachers can develop and use unfolding case studies to bring the subject to the center of the classroom. By doing so, the classroom becomes a place where students learn a sense of salience, develop their clinical imagination, and begin their formation as professional nurses.

    2008-01-01

    Parkour is an extreme sport that has been popular in Europe for a few years. This sport has now made it across the Atlantic and is quickly gaining popularity in the United States. Participants of this activity, known as parkouristes, try to overcome obstacles in their environment in the most efficient manner possible. This can be accomplished by simply jumping or scaling an obstacle, but sometimes this is done in a very acrobatic manner. The sport had a longtime underground following but has now gained media exposure through various television advertisements, and it has even been featured in recent blockbuster films. As a result, many amateurs are attempting to recreate these dangerous stunts without proper protection or guidance. We will review the case of an 18-year-old male who sustained multiple fracture/dislocations of his left foot while practicing parkour. ACFAS Level of Clinical Evidence: 4.

    From 2006-2010, Duke University's Center for Public Genomics prepared eight case studies examining the effects of gene patent licensing practices on clinical access to genetic testing for ten clinical conditions. One of these case studies focused on the successful licensing practices employed by the University of Michigan and the Hospital for Sick Children in Toronto for patents covering the CFTR gene and its ΔF508 mutation that causes a majority of cystic fibrosis cases. Since the licensing of these patents has not impeded clinical access to genetic testing, we sought to understand how this successful licensing model was developed and whether it might be applicable to other gene patents. We interviewed four key players who either were involved in the initial discussions regarding the structure of licensing or who have recently managed the licenses and collected related documents. Important features of the licensing planning process included thoughtful consideration of potential uses of the patent; anticipation of future scientific discoveries and technological advances; engagement of relevant stakeholders, including the Cystic Fibrosis Foundation; and using separate licenses for in-house diagnostics versus kit manufacture. These features led to the development of a licensing model that has not only allowed the patent holders to avoid the controversy that has plagued other gene patents, but has also allowed research, development of new therapeutics, and wide-spread dissemination of genetic testing for cystic fibrosis. Although this licensing model may not be applicable to all gene patents, it serves as a model in which gene patent licensing can successfully enable innovation, investment in therapeutics research, and protect intellectual property while respecting the needs of patients, scientists, and public health.

    Background Trachoma is widely considered a disease of poverty. Although there are many epidemiological studies linking trachoma to factors normally associated with poverty, formal quantitative data linking trachoma to household economic poverty within endemic communities is very limited. Methodology/Principal Findings Two hundred people with trachomatous trichiasis were recruited through community-based screening in Amhara Region, Ethiopia. These were individually matched by age and gender to 200 controls without trichiasis, selected randomly from the same sub-village as the case. Household economic poverty was measured through (a) A broad set of asset-based wealth indicators and relative household economic poverty determined by principal component analysis (PCA, (b) Self-rated wealth, and (c) Peer-rated wealth. Activity participation data were collected using a modified ‘Stylised Activity List’ developed for the World Bank’s Living Standards Measurement Survey. Trichiasis cases were more likely to belong to poorer households by all measures: asset-based analysis (OR = 2.79; 95%CI: 2.06–3.78; p<0.0001), self-rated wealth (OR, 4.41, 95%CI, 2.75–7.07; p<0.0001) and peer-rated wealth (OR, 8.22, 95% CI, 4.59–14.72; p<0.0001). Cases had less access to latrines (57% v 76.5%, p = <0.0001) and higher person-to-room density (4.0 v 3.31; P = 0.0204) than the controls. Compared to controls, cases were significantly less likely to participate in economically productive activities regardless of visual impairment and other health problems, more likely to report difficulty in performing activities and more likely to receive assistance in performing productive activities. Conclusions/Significance This study demonstrated a strong association between trachomatous trichiasis and relative poverty, suggesting a bidirectional causative relationship possibly may exist between poverty and trachoma.

    In March, 2010, the French Health Products Safety Agency suspended the sale of prefilled silicone breast implants manufactured by Poly Implants Prosthèse Prothese (PIP) because of a high failure rate and the use of an inappropriate silicone gel that did not comply with CE marking. These findings led to an international medical crisis. In France, 30,000 female patients had PIP implants. In our Department, 1150 PIP breast implants had been implanted in 630 patients since 2001. A retrospective study was conducted to define the rupture rate of these implants and the complications that arise. The women included in the study underwent implant removal from May 2010 to September 2012 for preventive or curative reasons. Data were collected from medical records that included: results of clinical examination, breast ultrasound before removal, rates of implant rupture, results of biopsy of periprosthetic capsule and pericapsule tissue and postoperative complications. A total of 828 PIP breast implants were removed in 455 patients. The rate of ruptured implants was 7.73% (64/828), corresponding to 11.6% of patients. A periprosthetic effusion was associated with rupture in 44% of cases. Breast ultrasound indicated a rupture for 87 implants; 32% were true positives and 3% were false negatives. Periprosthetic capsule biopsy demonstrated the presence of a foreign body, which seemed to be silicone, in 26% of cases and the presence of inflammation in 13% of cases. No siliconoma-type lesion was identified in the pericapsular tissue at biopsy. A total of 14 implants presented perspiration at removal. A statistically significant difference was found between the rates of rupture for texturised implants as compared to the smooth-surfaced implants. There were eight post-revisional-surgery complications (1%) and three cases of breast adenocarcinoma. The preventive explantation of PIP breast implants is justified given the high failure rate (7.73%) and given patients' exposure to silicone

    The maximum likelihood method is usually chosen to estimate the regression parameters of Generalized Linear Models (GLM) and also for hypothesis testing and goodness of fit tests. The classical method for estimating GLM parameters is the Fisher scores. In this work we propose to compute the estimates of the parameters with two alternative methods: a derivative-based optimization method, namely the BFGS method which is one of the most popular of the quasi-Newton algorithms, and the PSwarm derivative-free optimization method that combines features of a pattern search optimization method with a global Particle Swarm scheme. As a case study we use a dataset of biological parameters (phytoplankton) and chemical and environmental parameters of the water column of a Portuguese reservoir. The results show that, for this dataset, BFGS and PSwarm methods provided a better fit, than Fisher scores method, and can be good alternatives for finding the estimates for the parameters of a GLM.

    Despite substantial increases in solar photovoltaic (PV) deployment between 2005 and 2015, a large untapped market for solar PV deployment still exists in midscale market investments by universities. Recent estimates show that if all universities in the United States installed enough solar PV to meet 25% of their annual electricity consumption, this would cumulatively result in just over 16 gigawatts (GW) of additional installed PV capacity. Within this context, midscale market projects - loosely defined as solar PV installations ranging from 100 kilowatts (kW) to 2 megawatts (MW), but more broadly representing installations not captured in the residential or utility-scale sectors - could be an attractive option for universities. This case study focuses on one university solar customer, Colorado State University (CSU), to provide a detailed example of the challenges, solutions, and opportunities associated with university solar power procurement. Between 2009 and 2015, a combined 6,754 kW of both ground-mounted and rooftop solar PV was installed across multiple CSU campuses in Fort Collins, Colorado. This case study highlights CSU's decision-making process, campus engagement strategies, and relationships with state, local, and utility partners, which have culminated in significant on-campus PV deployment.

    2015-07-01

    Principles of extended producer responsibility have been the core of most of the recent policies and legislation dealing with the end-of-life management of recyclable goods. This article makes an exploratory review of 27 cases of extended producer responsibility from developed and developing economies with and without informal recycling, to ascertain the most important aspect of extended producer responsibility. A comparative analysis of the cases with respect to role of stakeholders in the upstream and downstream stages of the extended producer responsibility has been carried out. Further, the study uses exploratory factor analysis to determine the important aspects of the extended producer responsibility in practice using 13 variables identified from the review. Findings of the comparative analysis reveal that financial responsibility of the producers and separate collecting and recycling agencies contributed significantly to the success of the extended producer responsibility-based environmental policies. Regulatory provisions, take-back responsibility and financial flow come out to be the three most important aspects of the extended producer responsibility. Presence of informal sector had a negative impact on the regulatory provisions. The outcomes of this study could serve as a guideline for designing of effective extended producer responsibility-based policies.

    Primary amoebic meningoencephalitis (PAM) is a rare and rapidly fatal disease caused by the Naegleria fowleri amoeba. It is a diagnosis rarely seen by medical personnel, yet this amoeba is frequently encountered by people who frequent freshwater bodies of water in certain states. The disease primarily affects children and young adults who swim or take part in water sports in the waters in which the amoeba thrive. The disease presents with symptomatology similar to bacterial meningitis: headache, stiff neck, altered mental status, seizures, and coma with a quick progression to death. Rapid diagnosis is imperative to facilitate prompt treatment, although PAM has 95% mortality. There have been only 10 survivors reported in medical literature. This disease is a public-health risk to those living in affected areas of the country. Healthcare providers need to be cognizant of the disease as well, and, although recovery is rare, focus on prevention and risk reduction strategies is imperative. It is not completely understood why, of the millions of people are exposed to freshwater with the amoeba, only a few become infected with it. The Centers for Disease Control and Prevention have suggested that all freshwater areas should always assume a level of risk in waters, even when signage is not posted. This case study will review a fatal case of Naegleria fowleri infection in a young patient and will include the pathophysiology, diagnosis, treatment, nursing and public health implications, and organ procurement that occurred with the patient.

    2001-08-01

    A case-control study to evaluate risk factors for gastric cancer was carried out among 292 cases of gastric cancer and 485 controls in a high-risk area of Venezuela. Subjects were interviewed using a structured questionnaire, which elicited information on residential history, socio-economic status, family history of gastric diseases, smoking, drinking and dietary habits. Habitual diet was estimated from a meal-structured food frequency questionnaire on 75 food items. There was a strong inverse association with social class, as measured by education and by indicators of poverty. The results of the dietary analysis suggest that a diet high in starch and low in meat, fish and fresh vegetables increases risk of gastric cancer. A protective effect was observed for frequent consumption of allium vegetables. Inverse associations were found with height, which may reflect nutritional status in childhood, and with refrigerator use in the first two decades of life. Alcohol and tobacco consumption was investigated among males only, since the prevalence of alcohol and tobacco use was very low in females. Alcohol drinkers were at higher risk than non-drinkers and there was a small excess risk for current smokers compared with never smokers. There was some evidence of familial aggregation of gastric cancer. These findings will have important implications in planning preventive strategies for gastric cancer in Venezuela.

    2013-01-01

    Online risk prediction tools for common cancers are now easily accessible and widely used by patients and doctors for informed decision-making concerning screening and diagnosis. A practical problem is as cancer research moves forward and new biomarkers and risk factors are discovered, there is a need to update the risk algorithms to include them. Typically the new markers and risk factors cannot be retrospectively measured on the same study participants used to develop the original prediction tool, necessitating the merging of a separate study of different participants, which may be much smaller in sample size and of a different design. Validation of the updated tool on a third independent data set is warranted before the updated tool can go online. This article reports on the application of Bayes rule for updating risk prediction tools to include a set of biomarkers measured in an external study to the original study used to develop the risk prediction tool. The procedure is illustrated in the context of updating the online Prostate Cancer Prevention Trial Risk Calculator to incorporate the new markers %freePSA and [−2]proPSA measured on an external case control study performed in Texas, U.S.. Recent state-of-the art methods in validation of risk prediction tools and evaluation of the improvement of updated to original tools are implemented using an external validation set provided by the U.S. Early Detection Research Network.

  16. John Locke's seed lists: a case study in botanical exchange.

    PubMed

    Harris, Stephen A; Anstey, Peter R

    2009-12-01

    This paper gives a detailed analysis of four seed lists in the journals of John Locke. These lists provide a window into a fascinating open network of botanical exchange in the early 1680s which included two of the leading botanists of the day, Pierre Magnol of Montpellier and Jacob Bobart the Younger of Oxford. The provenance and significance of the lists are assessed in relation to the relevant extant herbaria and plant catalogues from the period. The lists and associated correspondence provide the main evidence for Locke's own important, though modest contribution to early modern botany, a contribution which he would have regarded as a small part of the broader project of constructing a natural history of plants. They also provide a detailed case study of the sort of open and informal network of knowledge exchange in the early modern period that is widely recognised by historians of science, but all too rarely illustrated.

  17. Catastrophic sinkhole formation in Kansas: A case study

    2006-01-01

    Sinkholes represent a hazard to property and human safety in a wide variety of geologic settings across the globe. In most cases, the subsidence rate of a sinkhole represents the most significant potential impact and risk to public safety. Since 1979, the Kansas Geological Survey has studied numerous sinkholes using high-resolution seismic reflection in an attempt to better understand the mechanisms that control their formation. Most sinkholes in central Kansas form as a result of dissolution of the Permian Hutchinson salt (Figure 1). The fluid source and associated pathway responsible for leaching these bedded evaporites have been natural, anthropogenic, and a combination of both. Sinkholes have been a part of the landscape in the North American midcontinent long before modern oil, gas, and mineral exploration, but clearly the activities of man have played a significant role in both increasing the number of sinkholes and affecting their subsidence rates.

    Spatial data mining is a process of discovering interesting, novel, and potentially useful information or knowledge hidden in spatial data sets. It involves different techniques and different methods from various areas of research. A Bayesian network is a graphical model that encodes causal probabilistic relationships among variables of interest, which has a powerful ability for representing and reasoning and provides an effective way to spatial data mining. In this paper we give an introduction to Bayesian networks, and discuss using Bayesian networks for spatial data mining. We propose a framework of spatial data mining based on Bayesian networks. Then we show a case study and use the experimental results to validate the practical viability of the proposed approach to spatial data mining. Finally, the paper gives a summary and some remarks.

    A case study, the Piano della Rocca dam (southern Italy) is discussed here in order to quantify the system performances under climate variability conditions. Different climate scenarios have been stochastically generated according to the tendencies in precipitation and air temperature observed during recent decades for the studied area. Climate variables have then been filtered through an ARMA model to generate, at the monthly scale, time series of reservoir inflow volumes. Controlled release has been computed considering the reservoir is operated following the standard linear operating policy (SLOP) and reservoir performances have been assessed through the calculation of reliability, resilience and vulnerability indices (Hashimoto et al. 1982), comparing current and future scenarios of climate variability. The proposed approach can be suggested as a valuable tool to mitigate the effects of moderate to severe and persistent droughts periods, through the allocation of new water resources or the planning of appropriate operational rules.

    Objective The exact role of calcified neurocysticercotic lesions (CNLs) in epilepsy is yet unknown and controversial. Although the relationship between CNLs, epilepsy and mesial temporal lobe epilepsy with hippocampal sclerosis (MTLE-HS) has already been addressed, to our knowledge, no study has actually provided strong statistical evidence, nor reported the ODDS ratio for these associations. Therefore, we designed this case-control study to assess the likelihood of having MTLE-HS versus other forms of epilepsy in the presence of CNLs. Methods In this case-control study we included 119 consecutive patients with epilepsy and 106 disease controls (headache) with previous CT scans. We subdivided cases into MTLE-HS and other epilepsies. We used brain CT scans to define presence or absence of CNLs. After exploratory analyses, we used logistic regression to analyze the association between CNLs, epilepsy subgroups and disease controls. Results CNLs were found in 31.09% of cases and in 11.32% of controls (p<0.001). The initial analysis comparing epilepsy versus controls revealed a significant association between CNLs and epilepsy (OR = 5.32; 95%CI = 2.43-11.54; p<0.001). However, when we compared MTLE-HS versus other epilepsies versus controls we confirmed that CNLs were associated with MTLE-HS (OR = 11.27, 95%CI = 4.73-26.85; p<0.001) but other epilepsies were not. We found no difference in the CNLs load and no difference in the location of the CNLs when we compared patients with MTLE-HS, other epilepsies and disease controls. Significance The inclusion of controls allowed us to estimate the likelihood of having epilepsy in the presence of CNLs. We found that patients with CNLs were 11 times more likely to have MTLE-HS; however, the presence of CNLs did not change the odds of having other types of epilepsy. These findings raise the possibility of neurocysticercosis playing a role in the pathophysiology of MTLE-HS and need further confirmation in other series. PMID
