A narrative literature review of the therapeutic effects of music upon childbearing women and neonates.  

Science.gov (United States)

Therapeutic effects of music are well recognised within the literature, with benefits for a variety of health problems documented. This narrative review summarises benefits in terms of reducing stress, anxiety, labour pain and depression in childbearing women. For neonates, music has been shown to reduce number of days to discharge, reduce pain response behaviours, increase weight gain, improve Brazelton scores, improve parent/infant intimacy, improve oxygen saturation, increase formula intake, stabilize vital signs and increase parental reports of calmed infants. The main criticism of the studies reviewed is lack of categorisation of the particulars of the variables within the music that directly influenced outcome variables. A recommendation is made that a music package be developed and relationships with variables rigorously evaluated. The validated product may then be made available for use. Since evidence supports advantages from listening to music, it is suggested that maternity professionals use it in more creative ways. PMID:25193325

Comprehensive Primary Health Care in Australia: findings from a narrative review of the literature  

Directory of Open Access Journals (Sweden)

Full Text Available Objectives: To identify the extent to which the Alma Atadefined Comprehensive Primary Health Care (CPHC approachis practised and evaluated in Australia and to describe the rolethat GPs and other medical practitioners play in it along withimplications of this for future policy in light of the Health andHospital Reform Commission (HHRC and Primary Health Caretaskforce reports, 2009 recommendations.Methods: We conducted a narrative review of the literature(published and grey from 1987 to mid 2007 as part of a globalreview carried out by teams of researchers in six regions in2007.Results: In Australia, the CPHC approach occurs chiefly inAboriginal Controlled Community Health Services, statefunded community health and in rural/remote and inner cityareas. Participation by GPs in CPHC is limited by fundingstructures, workforce shortages and heavy workloads. Factorsthat facilitated the CPHC approach include flexibility infunding and service provision, cultural appropriateness ofservices, participation and ownership by local consumers andcommunities and willingness to address the socialdeterminants of health.Conclusions: The recent HHRC and Primary Health CareTaskforce reports recommend an expansion of CPHC servicesas a means of tackling health inequities. The findings of thisreview suggest that resources will need to be directedbeyond individual treatment to population health issues,cross-sector collaboration and consumer participation inorder to realise the CPHC model. Without attention tothese areas PHC will not be comprehensive and its abilityto contribute to reducing inequities will be severelyhampered. The absence of an evaluation culturesupported with resources for CPHC programs and servicesalso hinders the ability of practitioners and policy makersto assess the benefits of these programs and how theirimplementation can be improved. Funding structures,workforce issues and evaluation of programs will all needto be addressed if the health sector is to contribute to thegoal of reducing health inequities.

Use of Mobile Phone Text Message Reminders in Health Care Services: A Narrative Literature Review  

Science.gov (United States)

Background Mobile text messages are a widely recognized communication method in societies, as the global penetration of the technology approaches 100% worldwide. Systematic knowledge is still lacking on how the mobile telephone text messaging (short message service, SMS) has been used in health care services. Objective This study aims to review the literature on the use of mobile phone text message reminders in health care. Methods We conducted a systematic literature review of studies on mobile telephone text message reminders. The data sources used were PubMed (MEDLINE), CINAHL, Proquest Databases/ PsycINFO, EMBASE, Cochrane Library, Scopus, and hand searching since 2003. Studies reporting the use of SMS intended to remind patients in health services were included. Given the heterogeneity in the studies, descriptive characteristics, purpose of the study, response rates, description of the intervention, dose and timing, instruments, outcome measures, and outcome data from the studies were synthesized using a narrative approach. Results From 911 initial citations, 60 studies were included in the review. The studies reported a variety of use for SMS. Mobile telephone text message reminders were used as the only intervention in 73% (44/60) of the studies, and in 27% (16/60) of the remaining studies, SMS was connected to another comprehensive health intervention system. SMS reminders were sent to different patient groups: patients with HIV/AIDS (15%, 9/60) and diabetes (13%, 8/60) being the most common groups. The response rates of the studies varied from 22-100%. Typically, the text message reminders were sent daily. The time before the specific intervention to be rendered varied from 10 minutes (eg, medication taken) to 2 weeks (eg, scheduled appointment). A wide range of different evaluation methods and outcomes were used to assess the impact of SMS varying from existing databases (eg, attendance rate based on medical records), questionnaires, and physiological measures. About three quarters of the studies (77%, 46/60) reported improved outcomes: adherence to medication or to treatment reportedly improved in 40% (24/60) of the studies, appointment attendance in 18% (11/60) of the studies, and non-attendance rates decreased in 18% (11/60) of the studies. Other positive impacts were decreased amount of missed medication doses, more positive attitudes towards medication, and reductions in treatment interruptions. Conclusions We can conclude that although SMS reminders are used with different patient groups in health care, SMS is less systematically studied with randomized controlled trial study design. Although the amount of evidence for SMS application recommendations is still limited, having 77% (46/60) of the studies showing improved outcomes may indicate its use in health care settings. However, more well-conducted SMS studies are still needed. PMID:25326646

The (mis)Measurement of M&A Performance : A Systematic Narrative Literature Review  

DEFF Research Database (Denmark)

This paper seeks to further the understanding of the variety of meanings M&A scholars attach to the label “M&A performance” by providing an alternative way to interpret the claimed inconsistency of M&A research findings. While many scholars contend that the problem stems from the multiplicity of M&A performance measures, we believe the problem rests in trying to compare different measures as if they were measuring the same feature of the organization. Through our narrative review of empirical research we analyze factors shaping the M&A – as well as the organizational – performance measurement process. The conclusion is that it is not possible to talk about M&A performance as if it was a universal construct.

Current status of emergency department triage in mainland China: A narrative review of the literature.  

Science.gov (United States)

In this review, the current status of emergency department triage in mainland China is explored, with the purpose of generating a deeper understanding of the topic. Literature was identified through electronic databases, and was included for review if published between 2002 and 2012, included significant discussion of daily emergency department triage in mainland China, was peer reviewed, and published in English or Chinese. Thematic analysis was used to identify themes which emerged from the reviewed literature. This resulted in 21 articles included for review. Four themes emerged from the review: triage process, triage training, qualification of triage nurses, and quality of triage. The review demonstrates that there is currently not a unified approach to emergency department triage in mainland China. Additionally, there are limitations in triage training for nurses and confusion around the role of triage nurses. This review highlights that emergency department triage in mainland China is still in its infancy and that more research is needed to further develop the role of triage. PMID:25196171

Human Papilloma Virus and oral cancer: Narrative review of the literature  

Directory of Open Access Journals (Sweden)

Full Text Available ABSTRACT The Human Papilloma Virus (HPV infection is now more common sexually transmitted diseases, with an incidence of 5.5 million worldwide, with 85% of the carrier of this virus adult population. Their oncogenic potential and increased oral lesions associated with oral HPV infection have led us to make a narrative of the literature on the role of HPV in oral cancer, especially types 16 and 18. Here we refer to the possible routes of infection, oncogenic mechanisms, both benign and potentially malignant oral lesions associated with the infection, different methods used for detection, prediction and prevention of infection. We stress the importance of the role of the dentist to identify individuals considered high risk and ease of performing detection in the oral cavity, through a quick and easy method as exfoliative cytology. RESUMEN El Virus Papiloma Humano (VPH en la actualidad constituye la infección por transmisión sexual más frecuente, presentando una incidencia de 5,5 millones en el mundo, siendo un 85% de la población adulta portadora de este virus. Su potencial oncogénico y el aumento de lesiones orales asociadas a infección oral por VPH nos han llevado a realizar una narración de la literatura referente al rol del VPH en el cáncer oral, especialmente de los subtipos 16 y 18. Nos referiremos a sus posibles vías de contagio, mecanismos oncogénicos, lesiones orales tanto benignas como potencialmente malignas asociadas a su infección, diferentes métodos utilizados para su detección, pronóstico y prevención de contagio. Destacamos la importancia del rol del odontólogo para identificar individuos considerados de alto riesgo y la facilidad de realizar su detección en la cavidad oral, a través de un método rápido y sencillo como es la citología exfoliativa.

Risks to emergency medical responders at terrorist incidents: a narrative review of the medical literature.  

Science.gov (United States)

As the threat of international terrorism rises, there is an increasing requirement to provide evidence-based information and training for the emergency personnel who will respond to terrorist incidents. Current major incident training advises that emergency responders prioritize their own personal safety above that of the 'scene and survivors'. However, there is limited information available on the nature of these threats and how they may be accurately evaluated. This study reviews the published medical literature to identify the hazards experienced by emergency responders who have attended previous terrorist incidents. A PubMed literature search identified 10,894 articles on the subject of 'terrorism', and there was a dramatic increase in publications after the 9/11 attacks in 2001. There is heterogeneity in the focus and quality of this literature, and 307 articles addressing the subject of scene safety were assessed for information regarding the threats encountered at terrorist incidents. These articles demonstrate that emergency responders have been exposed to both direct terrorist threats and environmental scene hazards, including airborne particles, structural collapse, fire, and psychological stress. The emphasis of training and preparedness for terrorist incidents has been primarily on the direct threats, but the published literature suggests that the dominant causes of mortality and morbidity in responders after such incidents are the indirect environmental hazards. If the medical response to terrorist incidents is to be based on evidence rather than anecdote, analysis of the current literature should be incorporated into major incident training, and consistent collection of key data from future incidents is required.

Teachers' perspectives of supporting pupils with long-term health conditions in mainstream schools: a narrative review of the literature.  

Science.gov (United States)

Teachers are supporting an increasing number of pupils with long-term health conditions in mainstream schools. The aim of this literature review was to critically appraise and synthesise research that has examined teachers' perceptions of the key barriers and facilitators to supporting pupils with long-term conditions, teachers' training needs and interventions that aim to improve teachers' knowledge of long-term conditions, and teachers' confidence in supporting children and young people. A narrative literature review was conducted using a systematic search of computerised databases and manual searches of key journals and reference lists to retrieve studies published between 2003 and 2013. Studies were critically appraised and key themes across studies identified. In total, 61 papers from 58 studies were included in the review. The findings suggest that teachers receive little formal training relevant to long-term condition management and are fearful of the risks involved in teaching children and young people with long-term conditions. Communication between families, school and health and social care services appears to be poor. Educational programmes developed in conjunction with and/or delivered by healthcare professionals seem to have the potential to increase teachers' knowledge and confidence. This review suggests that healthcare professionals have an important role to play in supporting teachers in identifying and meeting the needs of pupils with long-term conditions. It is vital that pupils with long-term conditions receive appropriate care and support in schools to ensure their safety and help them to integrate with their peers and achieve their academic potential. Limitations in the current evidence are highlighted and implications for future research are identified. PMID:24666555

Background: Patients with ACS are at risk for both cardiac autonomic dysfunction and clinical depression. Both conditions can negatively impact the ability to recover from an acute physiological insult, such as unstable angina or myocardial infarction, increasing the risk for adverse cardiovascular outcomes. HRV is recognized as a reflection of autonomic function. Methods: A narrative review was undertaken to evaluate state-of-the-art clinical research, using the PubMed database, January 2013. The search terms “heart rate variability” and “depression” were used in conjunction with “acute coronary syndrome”, “unstable angina”, or “myocardial infarction” to find clinical studies published within the past 10 years related to HRV and clinical depression, in patients with an ACS episode. Studies were included if HRV measurement and depression screening were undertaken during an ACS hospitalization or within 2 months of hospital discharge. Results: Nine clinical studies met the inclusion criteria. The studies' results indicate that there may be a relationship between abnormal HRV and clinical depression when assessed early after an ACS event, offering the possibility that these risk factors play a modest role in patient outcomes. Conclusion: While a definitive conclusion about the relevance of HRV and clinical depression measurement in ACS patients would be premature, the literature suggests that these measures may provide additional information in risk assessment. Potential avenues for further research are proposed. Keywords: autonomic nervous system, depressive disorder, outcomes research, risk assessment

Crouzon's syndrome: literature review  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction: The Crouzon syndrome or craniofacial dysostosis type I is a rare disease that affects the craniofacial skeleton development. Although it is uncommon, it has a transmission risk of 50% when one of the parents is a carrier. Objective: Performing a literature review about the Crouzon Syndrome, with emphasis on the current aspects. Method: As a methodology, a search on databases on-line, such as Cochrane, LILACS, MEDLINE, OMIM and SciELO has been made, by applying for the search the key-word Crouzon's Syndrome for articles published until 2007, in addition to the literature already dedicated to the subject. Literature Review: This syndrome is characterized by craniofacial anomalies caused by the early loss of the cranium flexibility, and present since the birth with tendency to aggravation in time. The main clinic signs are craniosynostosis, hypertelorism, exophthalmia, external strabismus, "parrot-beaked nose", short upper lip, hypoplastic maxilla and a relative mandibular prognathism determining a mid-facial hypoplasia aspect. It is a hereditary affection with an autosomal dominant transmission with 100% of penetrance and large phenotypic scale. Final Considerations: The genetic advising and an individual study of each case are essential to promote the improvement of the diagnosis. An early multidisciplinary approach is necessary, with specific therapeutic program aiming at the prevention of late diagnosis effects.

Terapia cognitivo-conductual en esquizofrenia: una revisión narrativa de la literatura / Cognitive Behavioral Therapy In Schizophrenia: A Narrative Review of Literature  

Scientific Electronic Library Online (English)

Full Text Available SciELO Colombia | Language: Spanish Abstract in spanish Introducción: La esquizofrenia es un trastorno grave e incapacitante. Aunque el tratamiento farmacológico ha sido efectivo, hasta 60% de los pacientes muestran una respuesta insuficiente. Desde el inicio de las terapias psicológicas ha existido interés en el uso de estas intervenciones en pacientes [...] con psicosis. Objetivo: Revisar los aspectos más importantes de la terapia cognitivo conductual (TCC) en el tratamiento de pacientes con esquizofrenia y los datos más relevantes que sustentan su utilidad en este trastorno. Desarrollo: El psicoanálisis, la terapia conductual, la terapia de apoyo y las intervenciones familiares fueron las únicas intervenciones psicológicas durante largo tiempo. Se llegó al consenso de que el psicoanálisis no está indicado en estos pacientes. Las terapias conductuales más ortodoxas hicieron aportes importantes, pero han estado dirigidas a compensar el déficit comportamental. La terapia de familia ha demostrado efectos positivos en resultados clínicos importantes, como recurrencias psicóticas, rehospitalización y cooperación con el tratamiento. La TCC ha sido implementada para compensar algunos déficits y, principalmente, para complementar los tratamientos farmacológicos, así como para tratar síntomas positivos, emocionales y negativos. Conclusiones: Varios estudios controlados y metaanálisis han demostrado que la TCC es útil para reducir los síntomas positivos y tratar las alteraciones emocionales; también ha tenido impacto en los síntomas negativos. Abstract in english Introduction: Schizophrenia is a severe and disabling disorder. Although pharmacological treatment has been effective for this condition, up to 60% of patients show an insufficient response. Since the beginnings of psychological therapies, there has been an interest in these interventions in psychot [...] ic patients. Objectives: This paper reviews the most important aspects of CBT in the treatment of patients with schizophrenia and the most relevant data supporting its usefulness in this severe disorder. Development: Psychoanalysis, behavioral therapy, supportive therapy and family interventions were the only available psychotherapies for a long time. Consensus was reached in that psychoanalysis is not indicated in patients with schizophrenia. Orthodox behavioral therapy made valuable contributions, but was mostly aimed at compensating behavioral deficits. Family therapy has shown positive effects in important clinical outcomes like psychotic relapse, rehospitalization and medication compliance. Cognitive behavioral therapy (CBT) has been introduced not only for helping to compensate certain deficits of schizophrenia, but also to complement medication in the treatment of positive, emotional and negative symptoms. Conclusions: Several controlled studies and metanalysis have shown that CBT is useful in reducing positive symptoms, for treating emotional disorders, and has had some impact on negative symptoms.

Real Options Literature Review  

Directory of Open Access Journals (Sweden)

Full Text Available After 30 years of discussion and research, the academic community has established a complete theoretical system of real options and provided an excellent framework for the use of real options theory in the investment appraisal of high-tech projects. An option is an entitlement without any obligation and it has been used to describe a variety of management decisions in business investment. The description of management is effective and proper. Due to the introduction of real options theory, there has been a major breakthrough in the investment area. Project evaluation is the core content of bank credit risk assessment and business evaluation. The core content never changes from the investment evaluation framework to the credit risk evaluation framework. The project evaluation meets various needs of subject s in different ways. In this paper, the importance of real options is analyzed and the literature is reviewed

CROSSFLOW FILTRATON: LITERATURE REVIEW  

Energy Technology Data Exchange (ETDEWEB)

As part of the Filtration task EM-31, WP-2.3.6, which is a joint effort between Savannah River National Laboratory (SRNL) and the Pacific Northwest National Laboratory (PNNL), tests were planned to evaluate crossflow filtration in order to the improve the use of existing hardware in the waste treatment plants at both the Department of Energy (DOE) Savannah River Site (SRS) and Hanford Site. These tests included experiments to try different operating conditions and additives, such as filter aids, in order to create a more permeable filter cake and improve the permeate flux. To plan the SRNL tests a literature review was performed to provide information on previous experiments performed by DOE laboratories, and by academia. This report compliments PNNL report (Daniel, et al 2010), and is an attempt to try and capture crossflow filtration work performed in the past that provide a basis for future testing. However, not all sources on crossflow filtration could be reviewed due to the shear volume of information available. In this report various references were examined and a representative group was chosen to present the major factors that affect crossflow filtration. The information summarized in this review contains previous operating conditions studied and their influence on the rate of filtration. Besides operating conditions, other attempted improvements include the use of filter aids, a pre-filtration leaching process, the backpulse system, and various types of filter tubes and filter coatings. The results from past research can be used as a starting point for further experimentation that can result in the improvement in the performance of the crossflow filtration. The literature reviewed in this report indicates how complex the crossflow issues are with the results of some studies appearing to conflict results from other studies. This complexity implies that filtration of mobilized stored waste cannot be explained in a simple generic sense; meaning an empirical model develop from one waste-filter combination will more than likely not be applicable to another combination. It appears that filtration performance varies as wide as the range of the types of slurry wastes that exist. However, conclusions can be elicited from existing information so that filter performance can be better understood, and hopefully improved. Those conclusions and recommendations for the planned tests are listed.

Reporting bias in medical research - a narrative review  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Reporting bias represents a major problem in the assessment of health care interventions. Several prominent cases have been described in the literature, for example, in the reporting of trials of antidepressants, Class I anti-arrhythmic drugs, and selective COX-2 inhibitors. The aim of this narrative review is to gain an overview of reporting bias in the medical literature, focussing on publication bias and selective outcome reporting. We explore whether these types of bias have been shown in areas beyond the well-known cases noted above, in order to gain an impression of how widespread the problem is. For this purpose, we screened relevant articles on reporting bias that had previously been obtained by the German Institute for Quality and Efficiency in Health Care in the context of its health technology assessment reports and other research work, together with the reference lists of these articles. We identified reporting bias in 40 indications comprising around 50 different pharmacological, surgical (e.g. vacuum-assisted closure therapy, diagnostic (e.g. ultrasound, and preventive (e.g. cancer vaccines interventions. Regarding pharmacological interventions, cases of reporting bias were, for example, identified in the treatment of the following conditions: depression, bipolar disorder, schizophrenia, anxiety disorder, attention-deficit hyperactivity disorder, Alzheimer's disease, pain, migraine, cardiovascular disease, gastric ulcers, irritable bowel syndrome, urinary incontinence, atopic dermatitis, diabetes mellitus type 2, hypercholesterolaemia, thyroid disorders, menopausal symptoms, various types of cancer (e.g. ovarian cancer and melanoma, various types of infections (e.g. HIV, influenza and Hepatitis B, and acute trauma. Many cases involved the withholding of study data by manufacturers and regulatory agencies or the active attempt by manufacturers to suppress publication. The ascertained effects of reporting bias included the overestimation of efficacy and the underestimation of safety risks of interventions. In conclusion, reporting bias is a widespread phenomenon in the medical literature. Mandatory prospective registration of trials and public access to study data via results databases need to be introduced on a worldwide scale. This will allow for an independent review of research data, help fulfil ethical obligations towards patients, and ensure a basis for fully-informed decision making in the health care system.

Fissure minerals, literature review  

International Nuclear Information System (INIS)

This paper is a review of methods used for direct and indirect dating of tectonic events. Isotope geochemistry including stable isotopes as well as fission track- dating, fluid inclusion and thermoluminescens techniques have been considered. It has been concluded that an investigation of tectonic (and thermal) events should start with a detailed study of the mineral phases grown in seald fissures as well as minerals from fissure walls. This study should include phase identification, textures as well as mineral chemistry. The information from this study is fundamental for the decision of further investigations. Mineral chemistry including isotopes and fluid inclusion studies will give an essential knowledge about crystallization conditions for fissure minerals concerned. Direct dating using fission tracks as well as radioactive isotopes could be useful for some minerals. Application of thermoluminescens dating on fissure minerals is doubtful. (Auth.)

Delivering healthcare services to children with cerebral palsy and their families: a narrative review.  

Science.gov (United States)

Children with cerebral palsy have complex healthcare needs and often require complex multidisciplinary care. It is important for clinicians to understand which approaches to healthcare service delivery for this population are supported in the literature and how these should be applied in clinical practice. This narrative review aims to identify and review the evidence for current approaches to healthcare service delivery for children with cerebral palsy. Databases were searched using key terms to identify relevant research articles and grey literature from December 2011 to September 2013. Search results were screened and sorted according to inclusion and exclusion criteria. Thirty-two documents were included for evaluation and their content was analysed thematically. Three current approaches to healthcare service delivery for children with cerebral palsy identified in this narrative review were family-centred care, the World Health Organisation's International Classification of Functioning, Disability and Health, and collaborative community-based primary care. However, healthcare services for children with cerebral palsy and their families are inconsistently delivered according to these approaches and the identified guidelines or standards of care for children with cerebral palsy have limited incorporation of these approaches. Future research is required to investigate how these approaches to healthcare service delivery can be integrated into clinical practices to enable clinicians to improve services for this population.

Review Of Plutonium Oxidation Literature  

International Nuclear Information System (INIS)

A brief review of plutonium oxidation literature was conducted. The purpose of the review was to ascertain the effect of oxidation conditions on oxide morphology to support the design and operation of the PDCF direct metal oxidation (DMO) furnace. The interest in the review was due to a new furnace design that resulted in oxide characteristics that are different than those of the original furnace. Very little of the published literature is directly relevant to the DMO furnace operation, which makes assimilation of the literature data with operating conditions and data a convoluted task. The oxidation behavior can be distilled into three regimes, a low temperature regime (RT to 350 C) with a relatively slow oxidation rate that is influenced by moisture, a moderate temperature regime (350-450 C) that is temperature dependent and relies on more or less conventional oxidation growth of a partially protective oxide scale, and high temperature oxidation (> 500 C) where the metal autocatalytically combusts and oxidizes. The particle sizes obtained from these three regimes vary with the finest being from the lowest temperature. It is surmised that the slow growth rate permits significant stress levels to be achieved that help break up the oxides. The intermediate temperatures result in a fairly compact scale that is partially protective and that grows to critical thickness prior to fracturing. The growth rate in this regime may be parabolic or paralinear, depending on the oxiabolic or paralinear, depending on the oxidation time and consequently the oxide thickness. The high temperature oxidation is invariant in quiescent or nearly quiescent conditions due to gas blanketing while it accelerates with temperature under flowing conditions. The oxide morphology will generally consist of fine particles ( 250 (micro)m). The particle size ratio is expected to be < 5%, 25%, and 70% for fine, medium and large particles, respectively, for metal temperatures in the 500-600 C range.

A literature review of idea management  

DEFF Research Database (Denmark)

The objective of the paper is primarily to conduct a state-of-the-art literature review of Idea Management and secondary to point out unanswered questions which are left behind in the reviewed literature. Scientific knowledge is primarily represented in innovation management literature but also considerably in literature on software and IT. On the background of the literature review, there are some weaknesses in the literature to be considered. These weaknesses concern the understanding of how people interact with idea management in their daily work practices and how different types of ideas are included or excluded in the idea management processes.

Titanium allergy: a literature review.  

Science.gov (United States)

Titanium has gained immense popularity and has successfully established itself as the material of choice for dental implants. In both medical and dental fields, titanium and its alloys have demonstrated success as biomedical devices. Owing to its high resistance to corrosion in a physiological environment and the excellent biocompatibility that gives it a passive, stable oxide film, titanium is considered the material of choice for intraosseous use. There are certain studies which show titanium as an allergen but the resources to diagnose titanium sensivity are very limited. Attention is needed towards the development of new and precise method for early diagnosis of titanium allergy and also to find out the alternative biomaterial which can be used in place of titanium. A review of available articles from the Medline and PubMed database was done to find literature available regarding titanium allergy, its diagnosis and new alternative material for titanium.

The value and purpose of the traditional qualitative literature review.  

Science.gov (United States)

Both meta-analysis and traditional literature or narrative reviews strive to compile a great deal of information in an accessible and succinct manner. In recent years, social work researchers have been turning toward meta-analysis to identify issues in large areas of research. In order for meta-analysis to be a rigorous and objective source of information there are a certain set of assumptions that must be met about how to carry out the process of including and excluding various studies. However, when these assumptions are not met, the information provided can be misleading. Traditional literature reviews continue to offer a valid and important way to identify existing patterns and gaps in social work research. In fact, because they draw not only on quantitative (as does meta-analysis) but also qualitative studies their reach may often be broader. This paper examines the strengths, weaknesses and utility of both practices in social work research today. PMID:21082469

CSR within SMEs: Literature Review  

Directory of Open Access Journals (Sweden)

Full Text Available Although CSR has traditionally been associated with big business, the SME business sector is such a significant sector worldwide in terms of the economic, environmental and social impact it makes, that attention has been turned to discussion and analysis of principles and practice of CSR in small and medium size businesses. SMEs are not merely small versions of big businesses, so as a result a particularly fast-growing body of academic work has become focused on commitment to CSR in the sector. As a result, the aim of this article is to set out an analysis of the main work carried out on the subject of CSR in SMEs. The analysis is a four part summary. In the first part, we explore the definition and the main CSR practices found in SMEs. The second part relates to determining characteristics of commitment to CSR within SMEs. Next we set out the challenges for SMEs and the constraints made upon them by CSR. Finally, the last section deals with positive examples of CSR in SMEs. Taking this literature review summary as a structural basis we then go on to demonstrate 3 research methodologies.

Geopressured habitat: A literature review  

Energy Technology Data Exchange (ETDEWEB)

A literature review of the geopressured-geothermal habitat is summarized. Findings are presented and discussed with respect to the principal topics: Casual agents are both geological and geochemical; they include disequilibrium compaction of sediments, clay diagenesis, aquathermal pressuring, hydrocarbon generation, and lateral tectonic compression. The overall physical and chemical characteristics of the habitats are dictated by varying combinations of sedimentation rates, alteration mineralogy, permeability, porosity and pressure, temperature, fluid content and chemistry, and hydrodynamic flow. Habitat pressure seals are considered in terms of their formation processes, geologic characteristics, and physical behavior, including pressure release and reservoir pressure recharge on a geologic time scale. World-wide occurrence of geopressured-geothermal habitats is noted. The main thrust of this topic concerns the U.S.A. and Canada; in addition, reference is made to occurrences in China and indications from deep-sea vents, as well as the contribution of paleo-overpressure to habitat initiation and maintenance. Identification and assessment of the habitat is addressed in relation to use of hydrogeologic, geophysical, geochemical, and geothermic techniques, as well as well-logging and drill-stem-test data. Conclusions concerning the adequacy of the current state of knowledge and its applicability to resource exploration and development are set forth, together with recommendations for the thrust of future work.

Detection of practice pattern trends through Natural Language Processing of clinical narratives and biomedical literature.  

Science.gov (United States)

Clinical knowledge, best evidence, and practice patterns evolve over time. The ability to track these changes and study practice trends may be valuable for performance measurement and quality improvement efforts. The goal of this study was to assess the feasibility and validity of methods to generate and compare trends in biomedical literature and clinical narrative. We focused on the challenge of detecting trends in medication usage over time for two diseases: HIV/AIDS and asthma. Information about disease-specific medications in published randomized control trials and discharge summaries at NewYork-Presbyterian Hospital over a ten-year period were extracted using Natural Language Processing. This paper reports on the ability of our semi-automated process to discover disease-drug practice pattern trends and interpretation of findings across the biomedical and clinical text sources.

Narrative review of telemedicine consultation in medical practice  

Science.gov (United States)

Background The use of telemedicine has grown across several medical fields, due to the increasing number of “e-patients”. Objective This narrative review gives an overview of the growing use of telemedicine in different medical specialties, showing how its use can improve medical care. Methods A PubMed/Medline, Embase, Web of Science, and Scopus search was performed using the following keywords: telemedicine, teleconsultation, telehealth, e-health, and e-medicine. Selected papers from 1996 to 2014 were chosen on the basis of their content (quality and novelty). Results Telemedicine has already been applied to different areas of medical practice, and it is as effective as face-to-face medical care, at least for the diagnosis and treatment of some pathological conditions. Conclusion Telemedicine is time- and cost-effective for both patients and health care professionals, encouraging its use on a larger scale. Telemedicine provides specialist medical care to patients who have poor access to hospitals, and ensures continuity of care and optimal use of available health resources. The use of telemedicine opens new perspectives for patients seeking a medical second opinion for their pathology, since they can have remote access to medical resources that would otherwise require enormous costs and time.

Economic Value Added (EVA - Literature Review and Relevant Issues  

Directory of Open Access Journals (Sweden)

Full Text Available This paper aims to present a narrative literature review of 112 papers published on the EVA from 1994 to 2008. It provides a classification scheme, identifies the gaps in existing literature and suggests the direction for future research. Studies are classified and presented on the basis of the time period, issues covered, distribution of literature in various sources, methodology used, country-wise publications and contributions made by the researchers on the concept. The studies conducted in the developed countries have largely been found to be supporting EVA though there are certain studies in these countries too that consider conventional measures as better tools of corporate performance reporting. However, in developing economies less numbers of studies are available supporting the empirical validity of the concept as a corporate performance measurement tool. The concept of EVA has gained significant attention in the advanced economies, but implementation issues and its validity is under debate all over the world. The paper presents a comprehensive literature review and a critical analysis to move towards the advances in EVA. It may be a very useful source of information to the researchers and managers who wish to understand and implement EVA and carry out further research on the diverse issues of this interesting and value adding performance metric.

Cocaine and thrombosis: a narrative systematic review of clinical and in-vivo studies  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Purpose To systematically review the literature pertaining to the link between cocaine and either arterial or venous thrombosis. Procedures Narrative systematic review of Medline, CINAHL, Embase, Psycinfo and Cochrane databases supplemented by hand trawling of relevant journals and reference lists up to April 2007. In-vivo studies and those with clinical endpoints were included in the review. Results A total of 2458 abstracts led to 186 full-text papers being retrieved. 15 met the criteria for inclusion in the review. The weight of evidence would support cocaine as a pro-thrombotic agent. There is evidence of it activating thrombotic pathways. The effect of cocaine upon clinical endpoints has not been quantified though there is evidence of an association between cocaine and myocardial infarction particularly amongst young adults. Cocaine may also be a causal agent in cerebrovascular accident though studies lacked sufficient power to determine a statistically significant effect. There is a gap in the evidence pertaining to the issue of cocaine and venous thrombosis. Conclusion Clinicians should consider questioning for cocaine use particularly amongst young adults who present with cardiac symptoms. More epidemiological work is required to quantify the effect of cocaine upon both arterial and venous clotting mechanisms.

Genetic polymorphisms of vein wall remodeling in chronic venous disease: a narrative and systematic review.  

Science.gov (United States)

Chronic venous disease encompasses a spectrum of disorders caused by an abnormal venous system. They include chronic venous insufficiency, varicose veins, lipodermatosclerosis, postthrombotic syndrome, and venous ulceration. Some evidence suggests a genetic predisposition to chronic venous disease from gene polymorphisms associated mainly with vein wall remodeling. The literature exploring these polymorphisms has not been reviewed and compiled thus far. In this narrative and systematic review, we present the current evidence available on the role of polymorphisms in genes involved in vein wall remodeling and other pathways as contributors to chronic venous disease. We searched the EMBASE, Medline, and PubMed databases from inception to 2013 for basic science or clinical studies relating to genetic associations in chronic venous disease and obtained 38 relevant studies for this review. Important candidate genes/proteins include the matrix metalloproteinases (extracellular matrix degradation), vascular endothelial growth factors (angiogenesis and vessel wall integrity), FOXC2 (vascular development), hemochromatosis (involved in venous ulceration and iron absorption), and various types of collagen (contributors to vein wall strength). The data on associations between these genes/proteins and the postthrombotic syndrome are limited and additional studies are required. These associations might have future prognostic and therapeutic implications. PMID:25006132

Validity of claims made in weight management research: a narrative review of dietetic articles  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background The best available evidence demonstrates that conventional weight management has a high long-term failure rate. The ethical implications of continued reliance on an energy deficit approach to weight management are under-explored. Methods A narrative literature review of journal articles in The Journal of Human Nutrition and Dietetics from 2004 to 2008. Results Although the energy deficit approach to weight management has a high long-term failure rate it continues to dominate research in the field. In the current research agenda, controversies and complexities in the evidence base are inadequately discussed, and claims about the likely success of weight management misrepresent available evidence. Conclusions Dietetic literature on weight management fails to meet the standards of evidence based medicine. Research in the field is characterised by speculative claims that fail to accurately represent the available data. There is a corresponding lack of debate on the ethical implications of continuing to promote ineffective treatment regimes and little research into alternative non-weight centred approaches. An alternative health at every size approach is recommended.

A systematic narrative review of consumer-directed care for older people: implications for model development.  

Science.gov (United States)

Consumer-directed care is increasingly becoming a mainstream option in community-based aged care. However, a systematic review describing how the current evaluation research translates into practise has not been published to date. This review aimed to systematically establish an evidence base of user preferences for and satisfaction with services associated with consumer-directed care programmes for older people. Twelve databases were searched, including MedLine, BioMed Central, Cinahl, Expanded Academic ASAP, PsychInfo, ProQuest, Age Line, Science Direct, Social Citation Index, Sociological Abstracts, Web of Science and the Cochrane Library. Google Scholar and Google were also searched. Eligible studies were those reporting on choice, user preferences and service satisfaction outcomes regarding a programme or model of home-based care in the United States or United Kingdom. This systematic narrative review retrieved literature published from January 1992 to August 2011. A total of 277 references were identified. Of these 17 met the selection criteria and were reviewed. Findings indicate that older people report varying preferences for consumer-directed care with some demonstrating limited interest. Clients and carers reported good service satisfaction. However, research comparing user preferences across countries or investigating how ecological factors shape user preferences has received limited attention. Policy-makers and practitioners need to carefully consider the diverse contexts, needs and preferences of older adults in adopting consumer-directed care approaches in community aged care. The review calls for the development of consumer-directed care programmes offering a broad range of options that allow for personalisation and greater control over services without necessarily transferring the responsibility for administrative responsibilities to service users. Review findings suggest that consumer-directed care approaches have the potential to empower older people. PMID:23465034

Lamellar Keratoplasty: A Literature Review  

Science.gov (United States)

The concept of lamellar keratoplasty (LK) is not new. However, newer forms of lamellar keratoplasty techniques have emerged in the last decade or so revolving around the concept of targeted replacement of diseased corneal layers. These include anterior lamellar keratoplasty (ALK) techniques that aim to selectively replace diseased corneal stroma and endothelial keratoplasty techniques aiming to replaced damaged endothelium in endothelial disorders. Recent improvements in surgical instruments and introduction of new techniques as well as inherent advantages such as preservation of globe integrity and decreased graft rejection have resulted in the reintroduction of LK as an acceptable alternative to conventional PK. In this review, indications, benefits, limitations, and outcomes of various anterior and posterior lamellar keratoplasty techniques are discussed. PMID:24223301

Peripartum cardiomyopathy (A literature review  

Directory of Open Access Journals (Sweden)

Full Text Available Heart failure (HF is a serious and growing public health concern, which has many causes. Pregnancy is a critical condition with significant hemodynamic and immunologic changes. Peripartum cardiomyopathy (PPCM is a disease of unknown cause in which left ventricular (LV dysfunction occurs during the last trimester of pregnancy or the early puerperium. PPCM is known to be the most common cardiovascular cause of severe complications in pregnancy.  Risk factors for peripartum cardiomyopathy include advanced maternal age, twin pregnancy, smoking, pregnancy-related hypertension and preeclampsia, multiparity, African descent, and long-term tocolysis. Oxidative stress and some inflammatory markers have been diagnosed in PPCM pathophysiology. Recent observations have suggested that bromocriptine might favor recovery of LV systolic function in patients with PPCM. Patients developed peripartum cardiomiopathy treated with bromocriptine showed significantly improved LV ejection fraction and heart failure symptoms. This article tries to have a short review on this clinical scenario.

PELLETIZATION TECHNIQUES: A LITERATURE REVIEW  

Directory of Open Access Journals (Sweden)

Full Text Available In present times, the pelletization technologies are gaining much attention as they represent an efficient pathway for manufacture of oral drug delivery systems. This is due to the reason that pellets offer many therapeutic, technological as well as biopharmaceutical advantages over the conventional oral dosage forms. Pelletization technique enables the formation of spherical beads or pellets with a mean diameter usually ranging from 0.5-2.0 mm which can be eventually coated for preparation of modified release dosage forms. Pelletization leads to an improvement in flowability, appearance and mixing properties thus avoiding generation of excessive dust and reducing segregation, and, generally, eliminating undesirable properties and improving the physical and chemical properties of fine powders. Pellets are produced by various techniques, such as, extrusion/ spheronization, layering, cryopelletization, freeze pelletization, spray congealing, spray drying and compression. Amongst various techniques, Extrusion/Spheronization technique is the most widely utilized technique due to its high efficiency and simple and fast processing. The aim of this paper is to review some general aspects about pellets and pelletization and some common techniques being utilized in the pharmaceutical industry.

Invisible Colleges: A Literature Review  

Directory of Open Access Journals (Sweden)

Full Text Available Generation and consumption of information are among the functions unique to higher education. Scholarly communication plays an essential role in this process to such a degree that some consider it as being the cornerstone of science. Thus it could be said that no education could be realized without communication. Scientometrists analyze and assess formal scientific communications by studying the level of citation of such scientific outputs as books, journals and etc. Nevertheless, there is a special type of communication that lacks any external manifestation such as citations. Informal learning and education are indebted to such communication. This kind of informal communication for generating knowledge leads to an informal association among the scholars, which is called as "The invisible college". There are various definitions and interpretations concerning an invisible college. According to Price’s opinion, an invisible college is comprised of over a hundred colleagues that are engaged in communication with one another. He believed that members in such an association are reasonably in touch with and could consult and influence one another. The present paper, by reacquainting with the concept of invisible college, would review the role of informal links in the production of knowledge and higher education system, various assessment methods and critical notes, as well as the impact of modern ICT tools on the concept of invisible college.

TRANSPORT THROUGH CRACKED CONCRETE: LITERATURE REVIEW  

Energy Technology Data Exchange (ETDEWEB)

Concrete containment structures and cement-based fills and waste forms are used at the Savannah River Site to enhance the performance of shallow land disposal systems designed for containment of low-level radioactive waste. Understanding and measuring transport through cracked concrete is important for describing the initial condition of radioactive waste containment structures at the Savannah River Site (SRS) and for predicting performance of these structures over time. This report transmits the results of a literature review on transport through cracked concrete which was performed by Professor Jason Weiss, Purdue University per SRR0000678 (RFP-RQ00001029-WY). This review complements the NRC-sponsored literature review and assessment of factors relevant to performance of grouted systems for radioactive waste disposal. This review was performed by The Center for Nuclear Waste Regulatory Analyses, San Antonio, TX, and The University of Aberdeen, Aberdeen Scotland and was focused on tank closure. The objective of the literature review on transport through cracked concrete was to identify information in the open literature which can be applied to SRS transport models for cementitious containment structures, fills, and waste forms. In addition, the literature review was intended to: (1) Provide a framework for describing and classifying cracks in containment structures and cementitious materials used in radioactive waste disposal, (2) Document the state of knowledge and research related to transport through cracks in concrete for various exposure conditions, (3) Provide information or methodology for answering several specific questions related to cracking and transport in concrete, and (4) Provide information that can be used to design experiments on transport through cracked samples and actual structures.

Impact of perioperative hyponatremia in children: A narrative review  

Science.gov (United States)

For more than 50 years, hypotonic fluids (crystalloids) have been the standard for maintenance fluid used in children. In the last decade, several studies have evaluated the risk of hyponatremia associated with the use of hypotonic vs isotonic fluids, which has lead to an intense debate. Children undergoing surgery have several stimuli for release of antidiuretic hormone, which controls renal water handling, including pain, nausea, vomiting, narcotic use and blood loss. The body’s primary defense against the development of hyponatremia is the ability of the kidneys to excrete free water and dilute urine. Increased levels of antidiuretic hormone can result in hyponatremia, defined as a plasma sodium level hyponatremia is higher in children than in adults. It represents an emergency condition, and early diagnosis, prompt treatment and close monitoring are essential to reduce morbidity and mortality. The widespread use of hypotonic fluids in children undergoing surgery is a matter of concern and more focus on this topic is urgently needed. In this paper, we review the literature and describe the impact of perioperative hyponatremia in children. PMID:25374805

Violence and aggression: a literature review.  

Science.gov (United States)

This paper reports the results of a literature review that was undertaken to provide background for a small pilot study that introduced violence measurement instruments that was to assist the development of nursing practice on an acute psychiatric unit. Multiple databases were searched, focusing on publications since 1994: CINAHL, Ovid Healthstar, Ovid MEDLINE (R), EMBASE, and PsycINFO. The search used the following four groups of key word alternatives (used in truncated form to allow for ending permutations) in combination with each other: violence, aggression, dangerous; prediction, assessment, factor, risk, issue, cause, reason; mental, psychiatric; inpatient, short-term, acute, admission. Searching was supplemented with footnote chasing of those papers retrieved and existing resources of the first author. Consequently, the synthesis of the results discussed cannot be considered a systematic review of the literature and is a reflection of some of the key issues found in the literature. PMID:17880659

How can placebo effects best be applied in clinical practice? A narrative review  

Science.gov (United States)

Placebo effects are documented in a number of clinical and experimental studies. It is possible to benefit from placebo effects in clinical practice by using them as effects additive to those of documented and effective treatments. The purpose of this paper is to discuss how doctors and other health workers may benefit from placebo effects within an ethical framework. A narrative review of the literature relating to placebo effects in clinical practice was performed. We searched PubMed and selected textbooks on placebo effects for articles and book chapters relating to placebo effects in clinical practice. By drawing on placebo effects, doctors may access patients’ self-healing potentials. In practice, doctors may best benefit from placebo effects by influencing the patient’s expectations through communication. An important principle is to give the patient information stating that a particular treatment is effective, as long as this is based on realistic optimism. A patient-centered style involving elements such as developing trust and respect, exploring the patient’s values, speaking positively about treatments, and providing reassurance and encouragement might aid in activating placebo effects. The total effect of a documented treatment will partly depend on how well the placebo effects have been activated. Thus, placebo effects can be understood as a form of supplemental treatment.

Critical narrative review to identify educational strategies promoting physical activity in preschool.  

Science.gov (United States)

The aim of this narrative review is critically to evaluate educational strategies promoting physical activity that are used in the preschool setting in the context of obesity prevention programmes. Literature search was conducted between April and August 2010 in English and German databases (PubMED, PsychINFO, PSYNDEX, ERIC, FIS Bildung). Outcomes considered were time and intensity of physical activity, motor skills or measures of body composition. A total of 19 studies were included. Ten studies added physical activity lessons into their curriculum, one study provided more time for free play, eight studies focused on the social and play environment. Studies reporting positive outcomes implemented physical activity sessions that lasted at least 30 min d(-1). Several studies showed that children are most active in the first 10-15 min. The existence or installation of playground markings or fixed play equipment had no effect, whereas the presence or addition of portable play equipment was positively correlated with moderate-to-vigorous physical activity. Teacher training may be a key element for successful interventions. To overcome time constraints, a suggested solution is to integrate physical activity into daily routines and other areas of the preschool curriculum. PMID:22309068

The relationship among hypertension, antihypertensive medications, and osteoporosis: a narrative review.  

Science.gov (United States)

Osteoporosis and hypertension are two frequent diseases among the aging population that share a similar etiopathology and often coexist. Moreover, treatment of hypertension affects bone mineral density and, therefore, can worsen osteoporosis. This narrative review considers the influence of the main etiologic factors that contribute to the development of hypertension and osteoporosis and examines the effect of the most often used antihypertensives on bones. A computerized literature search of relevant English publications regarding the etiology of hypertension and osteoporosis as well as the impact of antihypertensives on osteoporosis from 1996 to 2011 was completed in October 2011. The latest update in the search was performed from May to June 2012. The most relevant nongenetic factors in the etiology of osteoporosis and hypertension are low calcium intake, vitamin D and vitamin K deficiency, high consumption of sodium salt, and the effects of different forms of nitric oxide. Thiazide diuretics are the only antihypertensives that have a positive influence on bone mineral density. For other antihypertensive drugs, the data are conflicting, indicating that they may have a potentially negative or positive influence on bone mineral density and fracture risk reduction. Some studies did not find a correlation between the use of antihypertensives and bone mineral density. Due to the frequent coexistence of hypertension and osteoporosis, when selecting long-term antihypertensive therapy the potential effects of antihypertensive drugs on development, worsening, or improvement of osteoporosis should also be considered.

Embedded Academic Librarianship: A Review of the Literature  

Directory of Open Access Journals (Sweden)

Full Text Available Objectives – The purpose of this review is to examine the development of embedded librarianship, its multiple meanings, and activities in practice. The review will also report on published outcomes and future research needs of embedded librarian programs.Methods – A search of current literature was conducted and summarized searching PubMed, CINAHL, Library, Information Science & Technology Abstracts (EBSCO, Academic Search Complete, and ERIC (EBSCO through August 23, 2012. Articles wereselected for inclusion in the review if they reported research findings related to embedded librarianship, if they provided unique case reports about embedded librarian programs, or if they provided substantive editorial comments on the topic. Relevant study findings were assessed for quality and presented in tabular and narrative form.Results – Currently, there is disparity in how embedded librarianship is being definedand used in common practice, ranging from embedding an online component into asingle course to full physical and cultural integration into an academic college orbusiness unit of an organization. Activities of embedded librarians include creatingcourse integrated instruction modules for either face-to-face or online courses, providingin depth research assistance to students or faculty, and co-locating within colleges orcustomer units via office hours for a few hours to all hours per week. Several case reports exist in the recent literature. Few high quality research studies reporting outcomes of librarians or library programs labeled as embedded exist at this point. Some evidence suggests that embedded librarians are effective with regards to student learning of information literacy objectives. Surveys suggest that both students and faculty appreciate embedded librarian services.Conclusion – Most published accounts discuss librarians embedding content and ready access to services in an online course management system. A few notable cases describe the physical and cultural integration of librarians into the library user environs. Future research using valid quantitative methods is needed to explore the impact of large scale, customized, embedded programs.

Nurse Caring: A Review of the Literature  

Directory of Open Access Journals (Sweden)

Full Text Available The purpose of this paper was to review the literature on caring among nurses. The approach utilized studies on nurse caring behaviors in a variety of patient care settings. Articles published between 1987-2012 in the CINAHL, Medline, and PubMed databases were used. Overall, fourteen different articles were deemed relevant and were included in the review. The review articles were grouped into three categories which were Acute/Surgical, Community/Institutionalized, and Postpartum/Childbirth. In conclusion, human needs assistance was a consistent aspect of caring valued by patients.  We recommend that nurses learn their patient’s likes and dislikes while also providing for topics related to patient physical needs. Also when caring for children, nurses should use entertainment and humor as part of their caring approach.

Narratives as an educational tool : a review of 'A Scientific Romance'  

Energy Technology Data Exchange (ETDEWEB)

This paper examined how the use of narratives can be used as a tool for educating the public on climate change with particular reference to Ronald Wright's 1997 novel entitled A Scientific Romance. The novel develops climate change as a central theme in the development plot and has received excellent reviews from literary critics in Canada, Great Britain and the United States. This paper reviewed the novel using criteria from both cognitive psychology and climatology. Cognitive theory claims that human beings think, perceive, understand and make choices according to narrative structures. This evaluation compared Wright's depiction of future climate change with scientific projections. Wright provides great detail regarding climatic conditions of the Great London-Thames Estuary region of Southern England in the years 2500-2501. The climatic variables used in the evaluation consist of surface temperature, sea level rise, precipitation and wind speed. This evaluation determined that Wright's narrative depiction of London's future climate is much more extreme than what scientists project. It was concluded that Wright's tightly woven narrative takes an abstract issue and successfully transforms it into something interesting and provides a detailed depiction of a plausible future climate and its implications for society. However, two minor weaknesses were found to exist. First, there is little reference to the major cause of climate change, and secondly, the climate scenario depicted in the novel is more consistent with the runaway greenhouse theory than with scientists' projections. It was cautioned that narratives must be used carefully and responsibly otherwise, the magnitude of portrayed changes may create a sense of disbelief or helplessness on the part of the public. 27 refs., 1 tab.

Social Marketing and Breastfeeding: A Literature Review  

Directory of Open Access Journals (Sweden)

Full Text Available Aims: Through the review of relevant literature this study illuminates the concepts of social marketing and breastfeeding. It specifically discusses the positioning of the link between social marketing and breastfeeding within different fields of study and develops a theoretical framework that tries to bridge the gap between those disciplines. Method: Various electronic databases were used and through systematic selection 11 scientific articles were identified that this literature review is based on. Results: The review indicates that the relationship between social marketing and breastfeeding is complex. There are indications that this relationship is being investigated within three distinct fields of research: psychology/education, public health and marketing. Depending on the research field the emphasis is put on either breastfeeding or social marketing as well as on the other concepts that were discovered to be of importance within this relationship. Namely, group and individual demography as well as behaviour were revealed to be important elements of the link between social marketing and breastfeeding. Conclusions: Based on the results this study concludes that a more multidimensional view on the relationship between the concepts under study is needed since the focus of previous studies is very one-sided and limited to just one element when all elements should be integrated equally.

Literature Review on Dynamic Cellular Manufacturing System  

Science.gov (United States)

In previous decades, manufacturers faced a lot of challenges because of globalization and high competition in markets. These problems arise from shortening product life cycle, rapid variation in demand of products, and also rapid changes in manufcaturing technologies. Nowadays most manufacturing companies expend considerable attention for improving flexibility and responsiveness in order to overcome these kinds of problems and also meet customer's needs. By considering the trend toward the shorter product life cycle, the manufacturing environment is towards manufacturing a wide variety of parts in small batches [1]. One of the major techniques which are applied for improving manufacturing competitiveness is Cellular Manufacturing System (CMS). CMS is type of manufacturing system which tries to combine flexibility of job shop and also productivity of flow shop. In addition, Dynamic cellular manufacturing system which considers different time periods for the manufacturing system becomes an important topic and attracts a lot of attention to itself. Therefore, this paper made attempt to have a brief review on this issue and focused on all published paper on this subject. Although, this topic gains a lot of attention to itself during these years, none of previous researchers focused on reviewing the literature of that which can be helpful and useful for other researchers who intend to do the research on this topic. Therefore, this paper is the first study which has focused and reviewed the literature of dynamic cellular manufacturing system.

A literature review of safety culture.  

Energy Technology Data Exchange (ETDEWEB)

Workplace safety has been historically neglected by organizations in order to enhance profitability. Over the past 30 years, safety concerns and attention to safety have increased due to a series of disastrous events occurring across many different industries (e.g., Chernobyl, Upper Big-Branch Mine, Davis-Besse etc.). Many organizations have focused on promoting a healthy safety culture as a way to understand past incidents, and to prevent future disasters. There is an extensive academic literature devoted to safety culture, and the Department of Energy has also published a significant number of documents related to safety culture. The purpose of the current endeavor was to conduct a review of the safety culture literature in order to understand definitions, methodologies, models, and successful interventions for improving safety culture. After reviewing the literature, we observed four emerging themes. First, it was apparent that although safety culture is a valuable construct, it has some inherent weaknesses. For example, there is no common definition of safety culture and no standard way for assessing the construct. Second, it is apparent that researchers know how to measure particular components of safety culture, with specific focus on individual and organizational factors. Such existing methodologies can be leveraged for future assessments. Third, based on the published literature, the relationship between safety culture and performance is tenuous at best. There are few empirical studies that examine the relationship between safety culture and safety performance metrics. Further, most of these studies do not include a description of the implementation of interventions to improve safety culture, or do not measure the effect of these interventions on safety culture or performance. Fourth, safety culture is best viewed as a dynamic, multi-faceted overall system composed of individual, engineered and organizational models. By addressing all three components of safety culture, organizations have a better chance of understanding, evaluating, and making positive changes towards safety within their own organization.

Why residents should teach: A literature review  

Directory of Open Access Journals (Sweden)

Full Text Available Resident doctors contribute significantly to the quality of undergraduate medical training and it is assumed that by participating in the process, they also improve their own professional competency. We decided to investigate whether there is evidence to support this assumption. Our hypothesis, the physician-as-teacher rule, stated that 'A skilled teacher has an increased likelihood of becoming a competent clinician, than a skilled clinician has of becoming a competent teacher' . We conducted a literature review to search for evidence to confirm or refute this assumption. Twenty-four articles written after 1990 were identified as relevant from 132 references we generated by searching Medline. The identified articles were qualitatively reviewed to identify key research conclusions and/or main discussion points. The findings from the review were collated and discussed. None of the studies showed specific evidence of how teaching results in improved professional competence. However, there was evidence that teaching ability correlated positively with the perception of clinical competency. There was also need for improved supervision and training programmes for residents in teaching skills. The review provided evidence that teaching influenced the perceived professional competency of physicians positively. Physicians who were perceived as competent were those who taught effectively, and who had a basic understanding of teaching and learning. The review shows that training in teaching is essential for physicians, and that further research is still needed to demonstrate the effect of good teaching on professional competency.

A literature review on innovation management tools  

Directory of Open Access Journals (Sweden)

Full Text Available The study of a complex phenomenon such as innovation, influences and effects of which are tangible in manifold contexts, traditionally requires the integration of different levels of analysis and the interaction among distant disciplines. The enterprise appears to be the fundamental agent of economic change; in this context, innovation, by intervening in the sphere of technology, constitutes a fundamental dimension also for social change. In addition, it interacts in the circle of a complex matrix of cultural, economic and institutional factors which are the base of social and economical evolution. In this context, the research questions (RQ investigated by the authors are: “what is innovation?” [RQ 1] and “which are the main evolutions of innovation management models?” [RQ 2]. Literature on this matter has exponentially evolved in recent years. Nevertheless, innovation literature presents a large heterogeneity of results, while the innovation process concept itself is still poorly understood. In order to investigate the first research question, authors review forms and structures of innovation models developed throughout the years. At the end a discussion on the characteristics of literature evolution, through a strength-weakness analysis, is presented by the authors.

Enterprise Architecture Evaluation : A systematic literature review  

DEFF Research Database (Denmark)

By being holistically preoccupied with coherency among organizational elements such as organizational strategy, business needs and the IT functions role in supporting the business, enterprise architecture (EA) has grown to become a core competitive advantage. Though EA is a maturing research area, little has been done to understand how e.g. projects, application or other organizational elements contribute to the overall EA. The current paper presents a literature review on EA evaluation. Different types of evaluation are a necessity in order to ensure that EA demands are being met by disparate IT initiatives. Still, EA evaluation has attracted little attention within academic literature. Thus, the aim of the current review is to get an overview of the topic, which can serve as a foundation for further development of the field. Overall, the study shows that while little research has been done within this area, research is especially lacking regarding empirical studies of how EA evaluation unfolds in practice, while holistic views on EA evaluation is almost non-existing.

Fibromyalgia and temporomandibular dysfunction: a literature review  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction and objective: Several studies have associated temporomandibular disorders (TMD and fibromyalgia (FM finding a wide variation of results. The aim of this study was to review the literature about the relationship between TMD and FM. Literature review: For many years, TMD and FM were considered different clinical entities, but recently, some authors have reported that these two clinical situations have similarities. It is important to emphasize that both in FM and TMD pain is the main symptom, including pain in face, mandible, and headache. Besides, these pain syndromes are characterized by a decrease in pain threshold and in the capacity of attenuation of descending systems of pain modulation. The relationship of comorbidity between TMD and FM may indicate, therefore, the existence of some form of central sensitization, which is common to both diseases, sharing neurochemical events. In addition, it was found that the presence of TMD is a common finding in FM patients. Conclusion: It can be concluded that FM and TMD are distinct clinical entities, although they share common signs and symptoms, especially those related to pain. Furthermore, it was observed that the prevalence of TMD in FM patients is higher than the other way around. It is also important in the diagnosis of these two diseases the differentiation between trigger and tender points, thus avoiding false diagnoses of TMD in FM patients.

Zirconia in fixed prosthesis. A literature review  

Science.gov (United States)

Statement of problem: Evidence is limited on the efficacy of zirconia-based fixed dental prostheses. Objective: To carry out a literature review of the behavior of zirconium oxide dental restorations. Material and Methods: This literature review searched the Pubmed, Scopus, Medline and Cochrane Library databases using key search words “zirconium oxide,” “zirconia,” “non-metal restorations,” “ceramic oxides,” “veneering ceramic,” “zirconia-based fixed dental prostheses”. Both in vivo and in vitro studies into zirconia-based prosthodontic restoration behavior were included. Results: Clinical studies have revealed a high rate of fracture for porcelain-veneered zirconia-based restorations that varies between 6% and 15% over a 3- to 5-year period, while for ceramo-metallic restorations the fracture rate ranges between 4 and 10% over ten years. These results provoke uncertainty as to the long-term prognosis for this material in the oral medium. The cause of veneering porcelain fractures is unknown but hypothetically they could be associated with bond failure between the veneer material and the zirconia sub-structure. Key words:Veneering ceramic, zirconia-based ceramic restoration, crown, zirconia, tooth-supported fixed prosthesis. PMID:24596638

Medicinal leech therapy in pain syndromes: a narrative review.  

Science.gov (United States)

Medicinal leech therapy is used in a variety of conditions; most of which have pain as a major symptom. Its mode of action relies on the injection of leech saliva into patients' tissues during the process of blood withdrawal. Leech saliva contains active ingredients with anti-inflammatory, thrombolytic, anti-coagulant and blood- and lymph-circulation enhancing properties. A specific analgesic substance within the leech saliva is yet to be identified. Pain relief from leech therapy is rapid, effective and long-lasting in many conditions. This review compiles studies and case reports that provide clinical evidence for leech therapy's analgesic effects. PMID:24081747

Craniofacial fibrous dysplasia: Surgery and literature review  

Science.gov (United States)

Objective: To highlight the clinical and radiologic features and management of craniofacial fibrous dysplasia with review of literature. Materials and Methods: A retrospective review of 6 patients who underwent surgical treatment in a tertiary healthcare centre was done using the parameters of patients' details, clinical features, radiological findings, management and postoperative review. Results: Of the six patients, 3 females and 2 males were in the 2nd decade of life and 1 male in the 1st decade of life. The disease was restricted to maxilla in 3 patients, involved the temporal and frontal bones in addition to maxilla in one, involved the frontal bone in one patient and involved frontal and parietal bones in one patient. The primary reason for seeking treatment in all the 6 cases was facial deformity. There was absence of pain in all 6 cases. For surgical treatment in all three cases involving the maxilla, the approach was intraoral while bicoronal approach was used for the other three cases. Treatment consisted of surgical contouring and reshaping the area. All cases were followed up over a period of 2 years with no signs of recurrence. Conclusion: Treatment of craniofacial fibro-osseous lesions is highly individualized. Most cases of craniofacial fibrous dysplasia manifest as swellings that cause facial deformity and surgical recontouring after cessation of growth seems to provide the best results. PMID:23662263

Tobacco is a preventable cause of morbidity and mortality across the world. A recently infamous way of smoking tobacco is shisha. Shisha smoking is also known as water pipe, hookah and Narghile smoking. The percentage of shisha smokers is on the rise rapidly spanning the globe. A literature review was conducted to identify all evidence on the epidemiological variations and health effects of shisha smoking. "Pub med" is used as a searching tool to identify all relevant empirical studies conducted worldwide. A qualitative overview of evidence is presented. Exposure to Shisha smoking is significantly associated with low infant weight, heart rate variations, hyperglycemia and hypertriglyceridemia. Increased risk of carcinoma is also leagued with it including carcinomas of the pancreas and lung being at the forefront. In conclusion, this review identifies grounds of several adverse conditions being associated with the habit of shisha smoking. It also evaluates the relevant epidemiological variations around the globe. The review culminates in the importance of enlightening shisha smokers regarding its deleterious effects. PMID:24708750

Linguagem narrativa e fluência na síndrome de down: uma revisão / Narrative language and fluency in down syndrome: a review  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: Portuguese Abstract in portuguese A síndrome de Down é uma condição na qual os indivíduos apresentam comprometimento intelectual e alterações de linguagem oral. A disfluência de fala está presente tanto durante a conversa espontânea como em produções orais de narrativas direcionadas. Este estudo teve como principal objetivo revisar [...] a literatura sobre a disfluência e a narrativa em indivíduos com a síndrome de Down, publicada entre 2002 e 2012, em bases de dados eletrônicos. Foram encontrados 17 artigos e selecionados oito, de acordo com os critérios de inclusão e exclusão. Destes, dois discorriam especificamente sobre a disfluência na síndrome de Down, e seis sobre a narrativa nesta população. A deficiência intelectual é parte do fenótipo dos indivíduos com SD e, em decorrência do comprometimento intelectual, prejuízos na aquisição e no desenvolvimento da linguagem. Estudos específicos, principalmente sobre a fluência/disfluência; e, sobre o desempenho na tarefa da narrativa, ainda são escassos e inconclusivos. A disfluência não aparece na maioria das descrições do fenótipo de linguagem dos indivíduos com esta condição, que mereceria, estudos clínicos adicionais. Abstract in english Down’s syndrome is a condition in which individuals have intellectual impairment and oral language disorders. Speech disfluency is present during both spontaneous conversations as in productions of directed oral narratives.

There were 17 articles and eight were selected according to the criteria of inclusion and exclusion. Two of these articles specifically discoursed on dysfluency in Down’s syndrome and the other six on the narrative in this population. Intellectual disability is part of the phenotype of individuals with DS and, as a result of the intellectual impairment, losses occur on the acquisition and development of language. Specific studies about, mainly on fluency/disfluency, and the performance on a task of narrative and, are still scarce and inconclusive. Disfluency doesn’t appear in most descriptions of the language phenotype of individuals with this condition, which would deserve additional clinical studies.

Recovery of Navy distillate fuel from reclaimed product. Volume II. Literature review  

Energy Technology Data Exchange (ETDEWEB)

In an effort to assist the Navy to better utilize its waste hydrocarbons, NIPER, with support from the US Department of Energy, is conducting research designed to ultimately develop a practical technique for converting Reclaimed Product (RP) into specification Naval Distillate Fuel (F-76). This first phase of the project was focused on reviewing the literature and available information from equipment manufacturers. The literature survey has been carefully culled for methodology applicable to the conversion of RP into diesel fuel suitable for Navy use. Based upon the results of this study, a second phase has been developed and outlined in which experiments will be performed to determine the most practical recycling technologies. It is realized that the final selection of one particular technology may be site-specific due to vast differences in RP volume and available facilities. A final phase, if funded, would involve full-scale testing of one of the recommended techniques at a refueling depot. The Phase I investigations are published in two volumes. Volume 1, Technical Discussion, includes the narrative and Appendices I and II. Appendix III, a detailed Literature Review, includes both a narrative portion and an annotated bibliography containing about 800 references and abstracts. This appendix, because of its volume, has been published separately as Volume 2.

The value of nursing: a literature review.  

Science.gov (United States)

This article is part of a wider study entitled Value of Nursing, and contains the literature search from electronic databases. Key words for the search included 'values of nursing', 'values in nursing', 'organisational values' and 'professional identity'. Thirty-two primary reports published in English between 2000 and 2006 were identified. The findings highlight the importance of understanding values and their relevance in nursing and how values are constructed. The value of nursing is seen to be influenced by cultural change, globalization, and advancement in technology and medicine. These factors are crucial in providing a more structured and measured view of what nursing is, which will result in greater job satisfaction among nurses, better nurse retention and enhanced patient care within a supportive and harmonious organization. The findings of this review have implications for policy makers in recruitment and retention in determining the global value of nursing. PMID:17901183

Levosimendan in critical illness: a literature review.  

Science.gov (United States)

Levosimendan, the active enantiomer of simendan, is a calcium sensitizer developed for treatment of decompensated heart failure, exerts its effects independently of the beta adrenergic receptor and seems beneficial in cases of severe, intractable heart failure. Levosimendan is usually administered as 24-h infusion, with or without a loading dose, but dosing needs adjustment in patients with severe liver or renal dysfunction. Despite several promising reports, the role of levosimendan in critical illness has not been thoroughly evaluated. Available evidence suggests that levosimendan is a safe treatment option in critically ill patients and may reduce mortality from cardiac failure. However, data from well-designed randomized controlled trials in critically ill patients are needed to validate or refute these preliminary conclusions. This literature review is an attempt to synthesize available evidence on the role and possible benefits of levosimendan in critically ill patients with severe heart failure. PMID:24578748

Suicide in elderly people: a literature review.  

Science.gov (United States)

A literature review was carried out focusing on the main factors associated with suicidal ideation, attempts and completed suicide in elders. The following databases were searched: MEDLINE, PsychINFO, SciELO and Biblioteca Virtual em Violência e Saúde da BIREME (BIREME's Violence and Health Virtual Library), referring to the period from 1980 to 2008. Fifty-two references were selected and analyzed. They showed a strong relationship among suicide ideation, attempt and completion in elderly individuals, which results from the interaction of complex physical, mental, neurobiological and social factors. Suicide associated with depression in the elderly can be prevented, provided the person is properly treated. In Brazil, it is necessary to invest in research, given the persistent increase in suicide rates among aged people, especially among males. PMID:20676565

They are usually found by an autopsy, whether the patient is asymptomatic or has symptoms (i.e., abdominal/flank pain, hematuria, palpable mass). Today the widespread use of ultrasonography and computed tomography has increased the detection of clinically asymptomatic renal leiomyomas. The differential diagnosis between leiomyomas and other malignant lesions (above all renal cell carcinoma or leiomyosarcoma) is still possible by histological examination. Radiological examinations are not sufficient for the differential diagnosis. Renal leiomyomas have no aggressive behaviour and they usually do not metastasize. The prognosis, after surgery, is excellent without recurrence. We report a case of leiomyoma in a 31-year-old man who presented hematuria and flank pain. We also review the literature and provide a summary of clinical, radiological and histological features of renal leiomyomas. PMID:22511443

Sexual Function Following Burn Injuries: Literature Review.  

Science.gov (United States)

Sexual function is a profound facet of the human personality. Burns due their sudden and devastating nature can have longstanding effects on intimate function by virtue of physical sequelae as well as alterations in body image and perceived desirability. A considerable number of patients encounter problems with intimate function in burns rehabilitation; nevertheless, the topic appears to be poorly addressed in specialist centers worldwide. Review of the literature suggests that a number of parameters can affect the quality of sexual life following burn injuries including age at the time of injury, location, and severity of the burn as well as coping mechanisms employed by the individual survivor. Addressing issues of intimacy relies on awareness, education, and a holistic approach on behalf of the multidisciplinary team members and, to this effect, recommendations are made on managing sexual function concerns in burns rehabilitation.

Airship dynamics modeling: A literature review  

Science.gov (United States)

The resurgence of airships has created a need for dynamics models and simulation capabilities adapted to these lighter-than-air vehicles. However, the modeling techniques for airship dynamics have lagged behind and are less systematic than those for fixed-wing aircraft. A state-of-the-art literature review is presented on airship dynamics modeling, aiming to provide a comprehensive description of the main problems in this area and a useful source of references for researchers and engineers interested in modern airship applications. The references are categorized according to the major topics in this area: aerodynamics, flight dynamics, incorporation of structural flexibility, incorporation of atmospheric turbulence, and effects of ballonets. Relevant analytical, numerical, and semi-empirical techniques are discussed, with a particular focus on how the main differences between lighter-than-air and heavier-than-air aircraft have been addressed in the modeling. Directions are suggested for future research on each of these topics.

Temozolomide and unusual indications: review of literature.  

Science.gov (United States)

Temozolomide (TMZ) was first known to be useful as a radiosensitiser in both primary brain tumours like glioblastoma multiforme and oligodendroglioma. Later, TMZ proved its efficacy in the treatment of melanoma. Multiple publications have demonstrated the benefit of TMZ in terms of efficacy and tolerance (used as mono-therapy or as adjuvant chemotherapy) compared to the "gold standard" treatment of this kind of tumours. Furthermore, several recent clinical trials have shown the particular importance of TMZ in other types of cancer. This publication deals with the use of TMZ in cancers which are not formal indications for TMZ (excluding glioblastoma multiforme, oligodendroglioma and melanoma). It also includes a necessary review of recent literature about the role of TMZ in the treatment of brain metastases, lymphomas, refractory leukaemia, neuroendocrine tumours, pituitary tumours, Ewing's sarcoma, primitive neuroectodermal tumours, lung cancer and other tumours.

Software ecosystems – a systematic literature review.  

DEFF Research Database (Denmark)

A software ecosystem is the interaction of a set of actors on top of a common technological platform that results in a number of software solutions or services. Arguably, software ecosystems are gaining importance with the advent of, e.g., the Google Android, Apache, and Salesforce.com ecosystems. However, there exists no systematic overview of the research done on software ecosystems from a software engineering perspective. We performed a systematic literature review of software ecosystem research, analyzing 90 papers on the subject taken from a gross collection of 420. Our main conclusions are that while research on software ecosystems is increasing (a) there is little consensus on what constitutes a software ecosystem, (b) few analytical models of software ecosystems exist, and (c) little research is done in the context of real-world ecosystems. This work provides an overview of the field, while identifying areas for future research.

Reconstruction of sternal defect - a literature review.  

DEFF Research Database (Denmark)

OBJECTIVES: The management of sternal defects arisen after deep sternal wound infection is challenging and often requires extensive interdisciplinary teamwork between plastic and thoracic surgeons. In this study, the published literature on methods used to reconstruct sternal defects arisen as a result of deep sternal wound infection after open-heart surgery will be reviewed. DESIGN: The Cochrane, Embase, PubMed, and SveMed+ databases were searched in December 2011. Only papers regarding treatment of deep sternal wound infection after open-heart surgery in adults were included. RESULTS: The literature search identified 224 original papers that met the inclusion criteria. The majority dealt with surgical techniques. None of the studies regarding reconstructive options were designed as randomized controlled trials, and the levels of evidence are generally low. CONCLUSION: The treatment of deep sternal wound infection has evolved considerably, but there is still little consensus regarding optimal surgicalmanagement and a general lack of a standard treatment protocol. The use of muscle flap transposition is well documented. Recent studies recommend the use of topical negative pressure therapy as an adjunct to surgical reconstruction.

Energy storage: a review of recent literature  

International Nuclear Information System (INIS)

Recent literature on the technological and economic status of reversible energy storage has been reviewed. A broad range of research and development activities have been pursued between 1975 and the present. Most of this work has concentrated on improving technical and economic performance of previously known storage technologies. Hydraulic pumped storage with both reservoirs above ground and compressed air storage (1 plant) are the only methods that have been adopted by electric utilities. The need for electrical energy storage in Canada has not been acute because of the large proportion of hydraulic generation which incorporates some storge and, in most cases, can readily be used for load-following. Residential heat storage in ceramic room heaters has been used in Europe for several years. For Canadian climatic and market conditions larger, central heating units would be required. Residential heat storage depends upon utilities offering time-of-use rates and none in Canada do so at present. Most seasonal storage concepts depend upon storage of low-grade heat for district heating. The cost of energy storage is highly dependent upon annual energy throughput and hence favours smaller capacity systems operating on frequent charge/discharge cycles over long-term storage. Capital costs of energy storage methods from the literature, expressed in constant dollars, are compared graphically and tentative investment costs are presented for several storage methods

Radiation-induced morphea - a literature review.  

Science.gov (United States)

Radiation-induced morphea (RIM) is a rare and under-recognized skin complication of radiotherapy. It is commonly wrongly diagnosed as other dermatological conditions or malignancy because of similar clinical characteristics. This literature review analyses 66 cases that have been reported in the literature since 1989. The clinical appearance often includes pain and disfiguration of affected area, which may influence the patient's quality of life. There is no clear connection between the radiotherapy dose, the fractionation scheme, the use of a boost, age, the presence of other dermatological conditions or other connective tissue diseases and the occurrence of RIM. Its pathogenesis is still unclear, but several theories are proposed to explain this phenomenon. The available data suggest that the abnormally high secretion of some cytokines (interleukin 4, interleukin 5, transforming growth factor) induced by radiation causes an extensive fibrosis after an activation of fibroblasts. Histological confirmation is crucial in distinguishing RIM from similar-looking diseases, such as chronic radiation dermatitis, cancer recurrence, radiation, recall dermatitis, new carcinoma or cellulitis. There is no clear treatment regimen for this condition. Clinical outcome after therapy is often unsatisfactory. The commonly used methods and agents include: topical and systemic steroids, calcineurin inhibitors, systemic immunosuppressants including methotrexate, tacrolimus, heparin, hyaluronidase, phototherapy (UVA, UVA1, UVB, PUVA), systemic antibiotics, imiquimod, mycophenolate mofetil, photophoresis. The differential diagnosis is challenging and requires a multidisciplinary approach to avoid misdiagnosis and to plan appropriate treatment. PMID:25174551

Corporate reputation: a review of literature  

Directory of Open Access Journals (Sweden)

Full Text Available The term corporate reputation has been mentioned in academic papers for some decades however since the 90's the debate about it has been intensified by authors of different areas of study. Therefore, there is a growing pressure around the definition of a construct and the way to measure an organization's corporate reputation. The purpose of this article is to present a literature review on corporate reputation in three different perspectives. At first, we intended to go through the literature, pointing out the different definitions presented on this theme. The second aspect refers to the identification of terms related to corporate reputation, such as corporate brand, corporate identity and corporate communication. Finally, broadening the possibilities of future empiric works, a review of the different proposals of measuring the corporate reputation of organizations is made.O tema reputação corporativa tem sido objeto de estudos acadêmicos há algumas décadas, porém, somente a partir da década de 90 intensificou-se esse interesse, manifestado por autores de diferentes áreas de estudo. A diversidade de abordagens pressiona o debate sobre a definição de um constructo e sobre a forma mais adequada de mensuração da reputação corporativa de uma organização. O propósito deste artigo é realizar uma revis?o da literatura sobre a questão da reputação corporativa em três perspectivas distintas. Pretende-se, em primeiro lugar, percorrer a literatura sobre o assunto, apontando as diferentes definições apresentadas do tema. Em seguida, identificar os termos correlatos à reputação corporativa, como: marca corporativa, identidade corporativa e comunicação corporativa. E, finalmente, a fim de ampliar as possibilidades de trabalhos empíricos futuros, examinar criticamente as diferentes propostas de mensuração da reputação corporativa das organizações.

Biomechanical research in dance: a literature review.  

Science.gov (United States)

The authors reviewed the literature, published from 1970 through December 2009, on biomechanical research in dance. To identify articles, the authors used search engines, including PubMed and Web of Science, five previous review articles, the Dance Medicine and Science Bibliography, and reference lists of theses, dissertations, and articles being reviewed. Any dance research articles (English language) involving the use of electromyography, forceplates, motion analysis using photography, cinematography or videography, and/or physics analysis were included. A total of 89 papers, theses/dissertations, and abstracts were identified and reviewed, grouped by the movement concept or specialized movements being studied: alignment (n = 8), plié (8), relevé (8), passé (3), degagé (3), développé (7), rond de jambe (3), grand battement (4), arm movements (1), forward stepping (3), turns (6), elevation work (28), falls (1), and dance-specific motor strategies (6). Several recurring themes emerged from these studies: that elite dancers demonstrate different and superior motor strategies than novices or nondancers; that dancers perform differently when using a barre as opposed to without a barre, both in terms of muscle activation patterns and weight shift strategies; that while skilled dancers tend to be more consistent across multiple trials of a task, considerable variability is seen among participants, even when matched for background, years of training, body type, and other variables; and that dance teachers recommend methods of achieving movement skills that are inconsistent with optimal biomechanical function, as well as inconsistent with strategies employed by elite dancers. Measurement tools and the efficacy of study methodologies are also discussed. PMID:21442132

Promoting volunteer capacity in hospice palliative care: a narrative review.  

Science.gov (United States)

Hospice volunteers play an essential role in the primary care network for end of life. The purpose of this review was to examine the evidence on hospice volunteers published between 2002 and July 2012. An electronic search of PubMed, CINAHL and PsychINFO using controlled vocabulary, and a reference scan, yielded 54 studies focusing on hospice volunteers. Studies were primarily descriptive using quantitative, qualitative and mixed methods. Findings from studies were grouped thematically into descriptions of the work of hospice volunteers; recruitment, preparation and retention of hospice volunteers; and perspectives and outcomes of the volunteer role. A substantial body of evidence exists describing the roles, stresses and rewards of hospice volunteering. Less is known about how to adequately recruit, prepare and retain volunteers. A small but intriguing body of evidence exists around volunteers' contributions to family satisfaction and patient longevity. Although the evidence around hospice volunteers continues to grow, there is an urgent need for further research. Findings indicate that volunteers make important contributions to high quality end of life care. However, more focused research attention is required to better understand how to maximize this contribution while providing better support for volunteers. PMID:23277631

Occlusion and periodontics: a critical literature review  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction: Occlusal trauma is defined as an injury resulting intissues changes within the attachment apparatus as result of occlusalforce(s. Since 1901, when Karolyi reported a possible interactionbetween occlusal disharmony and periodontal alterations, severalstudies have tried to find scientific evidence that corroborates or not this interrelationship. Objective and literature review: In this paper,the authors review the studies that have analyzed traumatic occlusion as a presumed aggravating factor in periodontal disease, as well as those suggesting possible advantages with the concomitant use of occlusal and periodontal therapies. Even though there are still many doubts to be clarified in order to completely understand the effects of occlusal forces on the periodontium, it is well known that a functional occlusion is fundamental for the equilibrium of the diverse components of the stomatognathic system, including the periodontal tissues.Conclusion: An occlusal adjustment should be done, whenever it is indicated, as a routine procedure during periodontal treatment.Furthermore, it is evident that additional studies, with more precise and reproducible methodology, are needed in order to clarify the interaction between the occlusion with the periodontal tissues.

PERFORMANCE EVALUATION: LITERATURE REVIEW AND TIME EVOLUTION.  

Directory of Open Access Journals (Sweden)

Full Text Available Performance evaluation of an economic entity requires approaching several criteria, such as industry and economic entity type, managerial and entrepreneurial strategy, competitive environment, human and material resources available, using a system of appropriate performance indicators for this purpose.The exigencies of communication occurred on the growing number of phenomena that marked the global economy in recent decades (internationalization and relocation of business crises and turmoil in financial markets, demand performance measurement to be made in a comprehensive way by financial and non-financial criteria. Indicators are measures of performance used by management to measure, report and improve performance of the economic entity. The relationship between indicators and management is ensured by the existence of performance measurement systems. Studies to date indicate that economic entities using balanced performance measurement systems as a key management tool registered superior performance compared to entities not using such systems. This study attempts to address the issue of performance evaluation by presenting opinions of different authors concerning the process of performance measurement and to present, after revising the literature, the evolution of the performance evaluation systems. We tried to do this literature review because sustainable development and, therefore, globalization require new standards of performance that exceeds the economic field, both for domestic companies as well as international ones. So, these standards should be integrated into corporate strategy development to ensure sustainability of activities undertaken by harmonizing the economic, social and environmental objectives. To assess the performance of economic entities it is required that performance evaluation to be done with a balanced multidimensional system, including both financial ratios and non-financial indicators in order to reduce the limits of the two categories of indicators. Performance measurement and management can’t be separated; performance management is a philosophy that is supported by performance measurement. Performance management precedes performance measurement and creates the context for performance measurement.

Naringenin and atherosclerosis: a review of literature.  

Science.gov (United States)

Atherosclerosis is a multifactorial disease mainly caused by deposition of low-density lipoprotein (LD) cholesterol in macrophages of arterial walls. Atherosclerosis leads to heart attacks as well as stroke. Epidemiological studies showed that there is an inverse correlation between fruit and vegetable consumption and the risk of atherosclerosis. The promising effect of high vegetable and fruit containing diet on atherosclerosis is approved by several experimental studies on isolated phytochemicals such as flavonoids. Flavonoids are known to up-regulate endogenous antioxidant system, suppress oxidative and nitrosative stress, decrease macrophage oxidative stress through cellular oxygenase inhibition as well as interaction with several signal transduction pathways and from these ways, have therapeutic effects against atherosclerosis. Naringenin is a well known flavonoid belonging to the chemical class of flavanones. It is especially abundant in citrus fruits, especially grapefruits. A plethora of evidences ascribes to naringenin antiatherosclerotic effects. Naringenin abilities to decrease LDL and triglycerides as well as inhibit glucose uptake; increase high-density lipoprotein (HDL); co-oxidation of NADH; suppress protein oxidation; protect against intercellular adhesion molecule-1(ICAM-1); suppress macrophage inflammation; inhibit leukotriene B4, monocyte adhesion and foam cell formation; induce of HO-1 and G 0/G 1 cell cycle arrest in vascular smooth muscle cells (VSMC) and down regulate atherosclerosis related genes are believed to have crucial role in the promising role against atherosclerosis. In the present review, we have summarized the available literature data on the anti-atherosclerotic effects of naringenin and its possible mechanisms of action. PMID:25483717

Firefighters' noise exposure: A literature review  

Directory of Open Access Journals (Sweden)

Full Text Available Aim: To review the literature about the effects of environmental noise on the hearing ability of firefighters. Method: The PubMed and Scielo databases were searched and studies from 2002 to 2012 that included the keywords firefighters, noise, and hearing loss were identified. Initially, 24 studies were selected, but only 10 met the inclusion criteria of investigating the effects of occupational noise on firefighters. Results: Only 2 (20% studies quantified levels of sound pressure and performed audiological tests to identify associations with noise intensity and 3 (30% questionnaire-based studies reported that these professionals are more susceptible to hearing loss. Four (50% studies found that noise exposure damages the auditory system in this population. Discussion: These findings indicate that there is a necessity for preventive measures to be adopted by this population since it is considered to be at risk. Conclusion: In recent years, there have been few studies of firefighters' exposure to occupational noise, but our findings show the importance of new studies that include proper means of quantifying their exposure to noise in different work environments, in order to identify possible adverse conditions as well as to aid in the diagnosis of hearing loss.

Neurobrucellosis: three case reports and literature review  

Directory of Open Access Journals (Sweden)

Full Text Available Background Brucellosis is a multisystem disease which may present with a broad spectrum of clinical manifestations and complications. Neurobrucellosis is an uncommon complication of this infection. This article aims to present clinical manifestations and to discuss the clinical features and management of 3 neurobrucellosis cases. Methods The diagnosis, treatment, laboratory results and accessory examination findings of 3 patients with neurobrucellosis between August 2010 and March 2012 were retrospectively analyzed, and relevant literature was reviewed. Results All the 3 cases had definite history of exposure to epidemic areas or infectious diseases, and history of being infected with Brucella by drinking raw milk. During the screening because of fever for reasons unknown, they were proved to be infected with Brucella by etiological or serological tests. Initial clinical manifestations consisted of fever and headache, with meningitis symptoms and signs, spondylitis, uroschesis and constipation (which might be caused by lumbosacral nerve root lesion, or neurological manifestations in auditory nerve and abducent nerve, such as hearing loss and diplopia. All patients were treated with rifampicin, doxycycline plus trimethoprim-sulfamethoxazole or ceftriaxone. Conclusion Neurobrucellosis presents with various clinical signs and symptoms, and is often accompanied by systemic infection. Brucellosis should be kept in mind during the screening of fever for reasons unknown, and be differentiated from Mycobacterium tuberculosis infection. The combined treatment by antibotics of different pharmacological mechanisms with full dose and long range is effective, and the prognosis is favorable.

CAPITAL BUDGETING DECISIONS-REVIEW OF LITERATURE  

Directory of Open Access Journals (Sweden)

Full Text Available -The main objective of present study is to present review of literature related to capital budgeting decisions and to study the trends in using the capital budgeting techniques in depth. The study would facilitate the reader to know the past, current and future trend of capital budgeting techniques by the corporate houses. This study would provide guidelines to decision makers to make investing and financing decisions so that their profit get maximise at minimize risks.The secondary purpose of this study is to understand the rationale behind capital budgeting decisions. Whether such kinds of decisions affect the efficiency of the corporate houses. Efficiency either in terms of increase in revenue or decrease in costs of the operations. The benefits from large investments are received in some future period and the future is uncertain. For instance, a decision to acquire an asset that is going to last for 15 years requires a15-year forecast. A failure to forecast correctly will lead to serious errors which can be corrected only at a considerable expense. Future revenue involves estimating the size of the market for a product and the expected share of the firm in that. These estimates depend on a variety of factors, including price, advertising and promotions, and sales effort and so on. To what extend these estimates effect the quality of capital budgeting decisions is the more sophisticated way to explain the main objective of this study

Sexuality following trauma injury: A literature review  

Directory of Open Access Journals (Sweden)

Full Text Available Restoration of the quality of life (QoL of trauma injury survivors is the aim of trauma rehabilitation. It is generally acknowledged that sexuality is an important component of QoL; however, rehabilitation services frequently fall short of including sexuality as a matter of routine. The literature was reviewed to examine the experiences of trauma survivors from three groups: spinal cord injury (SCI, traumatic brain injury (TBI and burns. The focus was on the impact of trauma on the QoL to identify future research directions and to advocate for the inclusion of sexuality as an integral part of rehabilitation. Databases searched were Proquest, Ovid, Cinahl, Medline, PsycInfo and Cochrane Central Register of controlled trials. A total of 36 eligible studies were included: SCI (n = 25, TBI (n = 6, burns (n = 5. Four themes were identified across the three trauma groups that were labeled as physiological impact of trauma on sexuality, cognitive-genital dissociation (CGD, sexual disenfranchisement (SD and sexual rediscovery (SR. Trauma injury has a significant impact on sexuality, which is not routinely addressed within rehabilitation services. Further sexuality research is required among all trauma groups to improve rehabilitation services and in turn QoL outcomes for all trauma survivors.

Leishmaniasis in travelers: A literature review.  

Science.gov (United States)

Leishmaniasis is a vector-borne protozoan infection whose clinical spectrum ranges from asymptomatic infection to fatal visceral leishmaniasis. Over the last decades, an increase in imported leishmaniasis cases in developed, non-endemic countries, have been pointed-out from a review of the international literature. Among the possible causes are increasing international tourism, influx of immigrants from endemic regions and military operations. The main area for the acquisition of cutaneous leishmaniasis, especially for adventure travelers on long-term trips in highly-endemic forested areas, is represented from South America, whereas popular Mediterranean destinations are emerging as the main areas to acquire visceral variant. Leishmaniasis should be considered in the diagnostic assessment of patients presenting with a compatible clinical syndrome and a history of travel to an endemic area, even if this occurred several months or years before. Adventure travelers, researchers, military personnel, and other groups of travelers likely to be exposed to sand flies in endemic areas, should receive counseling regarding leishmaniasis and appropriate protective measures.

Djenkolism: case report and literature review.  

Science.gov (United States)

Djenkolism is an uncommon but important cause of acute kidney injury. It sporadically occurs after an ingestion of the djenkol bean (Archidendron pauciflorum), which is native to Southeast Asia. The clinical features defining djenkolism include: spasmodic suprapubic and/or flank pain; urinary obstruction; and acute kidney injury. The precise pathogenesis of acute kidney injury following djenkol ingestion remains unknown. However, it is proposed that an interaction between the characteristics of the ingested beans and the host factors causes hypersaturation of djenkolic acid crystals within the urinary system, resulting in subsequent obstructive nephropathy with sludge, stones, or possible spasms. We report a case of djenkolism from our rural clinic in Borneo, Indonesia. Our systematic literature review identified 96 reported cases of djenkolism. The majority of patients recovered with hydration, bicarbonate therapy, and pain medication. Three patients required surgical intervention; one patient required ureteral stenting for the obstructing djenkolic acid stones. Four of the 96 reported patients died from acute kidney failure. We stress the importance of awareness of djenkolism to guide medical practitioners in the treatment of this rare disease in resource-poor areas in Southeast Asia. PMID:24790471

Full Text Available Occupational therapy clinical documentation comprises all recorded information about a client/patient/user, from forwarding to discharge, and it may integrate the patient’s record or serve as support for the exclusive practice of occupational therapy. In Brazil, despite being a mandatory and routine practice, little scientific-technical material on the subject is available for the support of professionals. This study aimed to identify, through literature review, information for greater understanding and support to the practice of professional activity. The data were analyzed and presented according to the different themes identified, seeking common, complementary and divergent points on each theme. Twelve articles were included in the study. The information obtained addressed themes such as registration methods, perception and attitudes of professionals, communication and language, quality, and others. It was possible to achieve a preliminary approach to the subject and have an overview of aspects related to occupational therapy clinical documentation, but some segmented information and several weaknesses were found

New roles for pharmacists in community mental health care: a narrative review.  

Science.gov (United States)

Medicines are a major treatment modality for many mental illnesses, and with the growing burden of mental disorders worldwide pharmacists are ideally positioned to play a greater role in supporting people with a mental illness. This narrative review aims to describe the evidence for pharmacist-delivered services in mental health care and address the barriers and facilitators to increasing the uptake of pharmacist services as part of the broader mental health care team. This narrative review is divided into three main sections: (1) the role of the pharmacist in mental health care in multidisciplinary teams and in supporting early detection of mental illness; (2) the pharmacists' role in supporting quality use of medicines in medication review, strategies to improve medication adherence and antipsychotic polypharmacy, and shared decision making; and (3) barriers and facilitators to the implementation of mental health pharmacy services with a focus on organizational culture and mental health stigma. In the first section, the review presents new roles for pharmacists within multidisciplinary teams, such as in case conferencing or collaborative drug therapy management; and new roles that would benefit from increased pharmacist involvement, such as the early detection of mental health conditions, development of care plans and follow up of people with mental health problems. The second section describes the impact of medication review services and other pharmacist-led interventions designed to reduce inappropriate use of psychotropic medicines and improve medication adherence. Other new potential roles discussed include the management of antipsychotic polypharmacy and involvement in patient-centered care. Finally, barriers related to pharmacists' attitudes, stigma and skills in the care of patients with mental health problems and barriers affecting pharmacist-physician collaboration are described, along with strategies to reduce mental health stigma.

Suicide in deaf populations: a literature review  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Studies have found that deaf individuals have higher rates of psychiatric disorder than those who are hearing, while at the same time encountering difficulties in accessing mental health services. These factors might increase the risk of suicide. However, the burden of suicidal behaviour in deaf people is currently unknown. The aim of the present review was to provide a summary of literature on suicidal behaviour with specific reference to deaf individuals. The objectives of the review were to establish the incidence and prevalence of suicidal behaviour in deaf populations; describe risk factors for suicidal behaviour in deaf populations; describe approaches to intervention and suicide prevention that have been used in deaf populations. Methods A number of electronic databases (e.g. Medline, PsycINFO, CINAHL, EMBASE, Dissertation Abstracts International, Web of Science, ComDisDome, ASSIA, Education Sage Full Text, Google Scholar, and the grey literature databases FADE and SIGLE were explored using a combination of key words and medical subject headings as search terms. Reference lists of papers were also searched. The Science and Social Sciences Citation Index electronic databases were used to identify studies that had cited key papers. We also contacted experts and organisations with an interest in the field. Results Very few studies focussed specifically on suicide in deaf populations. Those studies that were included (n = 13 generally involved small and unrepresentative samples. There were limited data on the rate of suicidal behaviour in deaf people. One study reported evidence of hearing impairment in 0.2% of all suicide deaths. Another found that individuals with tinnitus seen in specialist clinics had an elevated rate of suicide compared to the general population. The rates of attempted suicide in deaf school and college students during the previous year ranged from 1.7% to 18%, with lifetime rates as high as 30%. Little evidence was found to suggest that risk factors for suicide in deaf people differed systematically from those in the general population. However, studies did report higher levels of depression and higher levels of perceived risk among deaf individuals than hearing control groups. No firm evidence was found regarding the effectiveness of suicide prevention strategies in deaf people, but suggested strategies include developing specific screening tools, training clinical staff, promoting deaf awareness, increasing the availability of specialist mental health services for deaf people. Conclusion There is a significant gap in our understanding of suicide in deaf populations. Clinicians should be aware of the possible association between suicide and deafness. Specialist mental health services should be readily accessible to deaf individuals and specific preventative strategies may be of benefit. However, further research using a variety of study designs is needed to increase our understanding of this issue.

Microalgae harvesting and processing: a literature review  

Energy Technology Data Exchange (ETDEWEB)

The objective of this report is to present a discussion of the literature review performed on methods of harvesting microalgae. There is no single best method of harvesting microalgae. The choice of preferable harvesting technology depends on algae species, growth medium, algae production, end product, and production cost benefit. Algae size is an important factor since low-cost filtration procedures are presently applicable only for harvesting fairly large microalgae. Small microalgae should be flocculated into larger bodies that can be harvested by one of the methods mentioned above. However, the cells' mobility affects the flocculation process, and addition of nonresidual oxidants to stop the mobility should be considered to aid flocculation. The decision between sedimentation or flotation methods depends on the density difference between the algae cell and the growth medium. For oil-laden algae with low cell density, flotation technologies should be considered. Moreover, oxygen release from algae cells and oxygen supersaturation conditions in growth medium support the use of flotation methods. If high-quality algae are to be produced for human consumption, continuous harvesting by solid ejecting or nozzle-type disc centrifuges is recommended. These centrifuges can easily be cleaned and sterilized. They are suitable for all types of microalgae, but their high operating costs should be compared with the benefits from their use. Another basic criterion for selecting the suitable harvesting procedure is the final algae paste concentration required for the next process. Solids requirements up to 30% can be attained by established dewatering processes. For more concentrated solids, drying methods are required. The various systems for algae drying differ both in the extent of capital investment and the energy requirements. Selection of the drying method depends on the scale of operation and the use for which the dried product is intended.

Djenkolism: case report and literature review  

Directory of Open Access Journals (Sweden)

Full Text Available Nur C Bunawan,1 Asghar Rastegar,2 Kathleen P White,3 Nancy E Wang41Alam Sehat Lestari Clinic, West Kalimantan, Borneo, Indonesia; 2Section of Nephrology, Department of Medicine, Yale University School of Medicine, New Haven, CT, USA; 3General Internal Medicine, Yale University School of Medicine, New Haven, CT, USA; 4Department of Surgery and Pediatric Emergency Medicine, Stanford University School of Medicine, Stanford, CA, USAAbstract: Djenkolism is an uncommon but important cause of acute kidney injury. It sporadically occurs after an ingestion of the djenkol bean (Archidendron pauciflorum, which is native to Southeast Asia. The clinical features defining djenkolism include: spasmodic suprapubic and/or flank pain; urinary obstruction; and acute kidney injury. The precise pathogenesis of acute kidney injury following djenkol ingestion remains unknown. However, it is proposed that an interaction between the characteristics of the ingested beans and the host factors causes hypersaturation of djenkolic acid crystals within the urinary system, resulting in subsequent obstructive nephropathy with sludge, stones, or possible spasms. We report a case of djenkolism from our rural clinic in Borneo, Indonesia. Our systematic literature review identified 96 reported cases of djenkolism. The majority of patients recovered with hydration, bicarbonate therapy, and pain medication. Three patients required surgical intervention; one patient required ureteral stenting for the obstructing djenkolic acid stones. Four of the 96 reported patients died from acute kidney failure. We stress the importance of awareness of djenkolism to guide medical practitioners in the treatment of this rare disease in resource-poor areas in Southeast Asia.Keywords: djenkolism, acute renal failure, acute kidney injury, tropical medicine

Herb-drug interactions: a literature review.  

Science.gov (United States)

Herbs are often administered in combination with therapeutic drugs, raising the potential of herb-drug interactions. An extensive review of the literature identified reported herb-drug interactions with clinical significance, many of which are from case reports and limited clinical observations. Cases have been published reporting enhanced anticoagulation and bleeding when patients on long-term warfarin therapy also took Salvia miltiorrhiza (danshen). Allium sativum (garlic) decreased the area under the plasma concentration-time curve (AUC) and maximum plasma concentration of saquinavir, but not ritonavir and paracetamol (acetaminophen), in volunteers. A. sativum increased the clotting time and international normalised ratio of warfarin and caused hypoglycaemia when taken with chlorpropamide. Ginkgo biloba (ginkgo) caused bleeding when combined with warfarin or aspirin (acetylsalicylic acid), raised blood pressure when combined with a thiazide diuretic and even caused coma when combined with trazodone in patients. Panax ginseng (ginseng) reduced the blood concentrations of alcohol (ethanol) and warfarin, and induced mania when used concomitantly with phenelzine, but ginseng increased the efficacy of influenza vaccination. Scutellaria baicalensis (huangqin) ameliorated irinotecan-induced gastrointestinal toxicity in cancer patients.Piper methysticum (kava) increased the 'off' periods in patients with parkinsonism taking levodopa and induced a semicomatose state when given concomitantly with alprazolam. Kava enhanced the hypnotic effect of alcohol in mice, but this was not observed in humans. Silybum marianum (milk thistle) decreased the trough concentrations of indinavir in humans. Piperine from black (Piper nigrum Linn) and long (P. longum Linn) peppers increased the AUC of phenytoin, propranolol and theophylline in healthy volunteers and plasma concentrations of rifamipicin (rifampin) in patients with pulmonary tuberculosis. Eleutheroccus senticosus (Siberian ginseng) increased the serum concentration of digoxin, but did not alter the pharmacokinetics of dextromethorphan and alprazolam in humans. Hypericum perforatum (hypericum; St John's wort) decreased the blood concentrations of ciclosporin (cyclosporin), midazolam, tacrolimus, amitriptyline, digoxin, indinavir, warfarin, phenprocoumon and theophylline, but did not alter the pharmacokinetics of carbamazepine, pravastatin, mycophenolate mofetil and dextromethorphan. Cases have been reported where decreased ciclosporin concentrations led to organ rejection. Hypericum also caused breakthrough bleeding and unplanned pregnancies when used concomitantly with oral contraceptives. It also caused serotonin syndrome when used in combination with selective serotonin reuptake inhibitors (e.g. sertraline and paroxetine). In conclusion, interactions between herbal medicines and prescribed drugs can occur and may lead to serious clinical consequences. There are other theoretical interactions indicated by preclinical data. Both pharmacokinetic and/or pharmacodynamic mechanisms have been considered to play a role in these interactions, although the underlying mechanisms for the altered drug effects and/or concentrations by concomitant herbal medicines are yet to be determined. The clinical importance of herb-drug interactions depends on many factors associated with the particular herb, drug and patient. Herbs should be appropriately labeled to alert consumers to potential interactions when concomitantly used with drugs, and to recommend a consultation with their general practitioners and other medical carers.

Systematic review of the literature on simulation in nursing education.  

Science.gov (United States)

Simulation-based learning is an educational intervention which creates an environment that is conducive to experiential learning. Despite the prevalence of research on the influence of simulation on nursing education, there is a dearth of literature on the effectiveness of simulation-based learning. This systematic review examines literature on simulation outcomes in nursing education from the years 2000-2010. The electronic databases reviewed for the systematic review of the literature included: CINAHL Plus, Medline, Health Source: Nursing/Academic Education, Google Scholar, and Digital Dissertations and Theses through ProQuest. The MeSH search terms included "simulation outcomes measurement" and "nursing education". Seventeen studies were included in the review of the literature. The literature was categorized into three themes; internal outcomes, external outcomes, and clinical evaluation. The available literature on simulation and nursing education provides evidence that that simulation is useful in creating a learning environment which contributes to knowledge, skills, safety, and confidence. This systematic review of the literature revealed a gap in the literature pertaining to the transfer of these outcomes to the clinical setting, and lays a foundation for further research on outcomes specific to simulation and nursing education.

Global health impacts due to infectious diseases and climate change: A narrative review  

Directory of Open Access Journals (Sweden)

Full Text Available According to the World Health Organization (WHO, environment is explained in terms of human health, such as physical, chemical and biological factors that are external to a person and all the related behavioral changes that affect population health. Quality of life and health is generally affected by people’s interaction with the environment.The purpose of this narrative review was to address various global health impacts such as heat wave impact, impact of floods and droughts, impact of allergens and impact of air pollution. A major emphasis of this review was on climatic impact on a variety of infectious diseases, particularly the interplay between ‘global warming’ and its effects on transmission of infectious diseases across the world. An analysis of vector borne disease transmission, infectious disease transmission modeling, in the backdrop of global warming, the concept of ‘one health’ and the effects of rising sea levels, which are purported to be due to global warming, were some of the highlighted issues addressed in this review. Towards the end, attention was drawn towards the limitations of addressing vector disease transmission related insufficient studies particularly studies which conduct predictive modeling of infectious disease transmission, which were marred by lack of innovation.

Solid fuel grindability: a literature review  

Energy Technology Data Exchange (ETDEWEB)

The most commonly used measurement of coal grindability is the Hardgrove Grindability Index (HGI) however, many solid fuels do not exhibit the grinding performance predicted by this index. Parameters which can influence grindability and possibly lead to inaccurate prediction of grindability as determined by HGI include: composition and texture, mineral components, brittleness, and rank (which establishes carbon, volatile matter, and moisture contents). Descriptions of these parameters are provided. Alternative measurements of grindability from literature are presented. The most promising may be a revision on the standard HGI, in which a mill capacity factor is derived from the number of mill rotations to crush coal to a specific fineness. 88 refs.

Creating Value through Virtual Teams: A Current Literature Review  

Directory of Open Access Journals (Sweden)

Full Text Available Globally, virtual teams (VT as ICT-enabled emergent network organisation forms have gained international validity by innovative organisations, with a corresponding surge of interest in understanding how organisations can leverage VT to create business value. Despite growing deliberations in VT literature on managing VT, tasks and outcomes, however, creating business value through VT remains an unresolved theoretical and pragmatic conundrum. A review of prior relevant literature is essential to advancing knowledge. The paucity of published review articles seems to have impeded the field’s accumulation of VT knowledge. This research, therefore, reviews the current literature on case studies of VT to address the question: What are organisational challenges in creating business value through VT in the organisation? The key challenges found in the literature are effective communication, knowledge sharing, trust, and interpersonal skills in the new virtual boundary-less environment. Drawing on the IT business value model, we also discuss their resource-based implications.

Mica pneumoconiosis--a literature review.  

Science.gov (United States)

Sixty-six cases of mica pneumoconiosis have been reported in the literature. Twenty-six of the cases suggest that pneumoconiosis may be caused by pure mica alone. In only six cases the diagnosis was based on clinical examination, radiography, and lung biopsy or autopsy results. In one of these six, doubt was raised by the authors about the purity of the mica exposure. Seven epidemiologic studies have been performed among mica-processing workers, and these studies are all cross-sectional. In addition 30 experimental investigations have been carried out. However, there are no controlled inhalation studies among them. The results from the intratracheal instillation studies do not give a unanimous conclusion as to whether pure mica is fibrogenic or not. Present knowledge suggests that pure mica is moderately toxic and may induce pneumoconiosis. Exposure to mica is usually associated with exposure to other minerals such as quartz and feldspar.

Allergy to cosmetics: a literature review.  

Science.gov (United States)

The term cosmetic has a broad definition and includes personal care products, hair care products, nail care products, and sunscreens. Modern cosmetics are safe for most users, and adverse reactions are very rare because the manufacturers invest heavily in safety, quality control, and product testing before releasing the product to the market. Despite these efforts, adverse reactions occur. Skin care products are major contributors to cosmetic allergic contact dermatitis (ACD), followed by hair care and nail care products. The most common allergens are fragrances and preservatives. The diagnosis of cosmetic allergy is established by reviewing the patient's clinical history and physical examination findings and confirmed with skin patch testing. Patch testing is the standard method for detecting allergens responsible for eliciting ACD. The purpose of this article was to review the prevalence, legislative laws, and role of patch testing in ACD. PMID:24201464

Early diagnosis of autism and impact on prognosis: a narrative review  

Directory of Open Access Journals (Sweden)

Full Text Available Elisabeth Fernell,1 Mats Anders Eriksson,1,2 Christopher Gillberg11Gillberg Neuropsychiatry Centre, Sahlgrenska Academy, University of Gothenburg, Gothenburg, Sweden; 2Department of Women's and Children's Health, Karolinska Institute, Stockholm, SwedenAbstract: Autism spectrum disorders involve a set of clinical phenotypes that mirror an early onset of neurodevelopmental deviations, with core symptoms that can probably be related to a deficiency in the social instinct. Underlying the cognitive impairments there are physiological brain problems, caused by a large number of medical factors. This narrative review of systematic reviews and meta-analyses from the last 5 years (2008–2012 presents aspects from many areas in autism spectrum disorder research, with a particular focus on early intervention and the subsequent impact on prognosis. Other major areas discussed are epidemiology, early symptoms and screening, early diagnosis, neuropsychology, medical factors, and the existence of comorbidities. There is limited evidence that any of the broadband “early intervention” programs are effective in changing the natural long-term outcome for many individuals with an early diagnosis of autism. However, there is some evidence that Early Intensive Behavioral Intervention (EIBI is an effective treatment for some children with ASD. Nevertheless, there is emerging consensus that early diagnosis and information are needed in order that an autism-friendly environment be “created” around affected individuals.Keywords: autism spectrum disorder, epidemiology, screening, etiology, intervention, outcome

Asphalt solar collectors: A literature review  

International Nuclear Information System (INIS)

Highlights: ? Solar energy can be harnessed by asphalt pavements. ? Research on asphalt thermal behavior and asphalt solar collectors is reviewed. ? Asphalt temperature is very sensitive to the variation of absortivity. ? Asphalt solar collector efficiency depends on flow rate and geometrical parameters. -- Abstract: Asphalt pavements subject to solar radiation can reach high temperatures causing not only environmental problems such as the heat island effect on cities but also structural damage due to rutting or hardening as a result of thermal cycles. Asphalt solar collectors are doubly effective active systems: as they solve the previously mentioned problems and, moreover, they can harness energy to be used in different applications. The main findings of the existing research on asphalt solar collectors are gathered together in this review paper. Firstly, the main heat transfer mechanisms involved in the solar energy collection process are identified and the most important parameters and variables are presented. After analyzing the theoretical foundations of the heat transfer process, this review focuses on the types of studies carried out so far on asphalt’s thermal behavior, different methodologies employed by other authors to study asphalt solar collectors and influence of the variables involved in thermal energy harvesting.

Irradiation preservation of seafood: Literature review  

International Nuclear Information System (INIS)

The application of gamma-irradiation for extending the shelf life of seafood has been of interest for many years. This report reviews a number of studies on seafood irradiation conducted over the past several years. Topics covered include seafood irradiation techniques and dosages, species applicability and differences, the effects of packaging on seafood preservation, and changes in organoleptic acceptability as a result of irradiation. Particular attention is given to radiation effects (likely and unlikely) of concern to the public. These include the potential for generation of toxic chemical products, botulinum toxin production, and other health concerns. No scientifically defensible evidence of any kind was found for any harmful effect of irradiation of seafoods at the doses being considered (less than 300 krad), and all indications are that irradiation is an acceptable and needed additional tool for seafood preservation. 49 refs., 14 figs., 14 tabs

LITERATURE REVIEW OF FIBER REINFORCED POLYMER COMPOSITES  

Directory of Open Access Journals (Sweden)

Full Text Available Polymer-matrix composites (PMCs have been used for a variety of structural memberships for chemical plants and airplanes, since they have outstanding performances, such as lightweight and good fatigue properties. To hold the long-term durability and to estimate the residual life of the composites under some hostile environments, it is an important issue to clarify the facture and/or the failure mechanism in each service conditions. Degradation of components made from polymeric materials occurs in a wide variety of environments and service conditions, and very often limits the service lifetime. Degradation occurs as the result of environment-dependent chemical or physical attack, often caused by a combination of degradation agents, and may involve several chemical and mechanical mechanisms. The main concern of this review will be to examine the causes of degradation of polymeric components from the completion of fabrication to ultimate failure.

Optimum Stimulation Level Theory: A Literature Review  

Directory of Open Access Journals (Sweden)

Full Text Available Optimum stimulation level theory (OSLT is a fairly influential theory with strong explanatory power. It establishes the relationships between individuals’ physio-psychological factors and cognitive/emotional/attitudinal/behavioral responses. It also provides insightful guidance for understanding the different patterns and characteristics in individuals’ daily and working life. This paper introduces the theoretical assumptions and main ideas of OSLT, and reviews the relevant confirmative studies as well as its main applications. Based on the comparison among three types of measurement scales and their different versions, this paper recommends Arousal Seeking Tendency II, Change Seeker Index and its short version. Several future studies have been identified, including the role of age, the internal processes and mechanisms. In addition, this paper points out that it is necessary to develop measurement scales upon different contexts and subjects, and to extend the theory to different research contexts and areas by combining with other relevant theories.

Styloid syndrome: A review of literature  

Directory of Open Access Journals (Sweden)

Full Text Available The American otolaryngologist Eagle was the first to describe styloid syndrome in 1937. Stylohyoid complex is composed of styloid process, stylohyoid ligament and a lesser horn of the hyoid bone. Embriologicaly, these anatomical structures originate from Reichert's cartilage of the second brachial arch. In the general population, the frequency of the elongated styloid process is estimated to be 4%, of which only 4% show clinical manifestations suggesting that the incidence of styloid syndrome is 0.16% (about 16,000 persons in Serbia. The styloid process deviation causes external or internal carotid impingement and pains which radiate along the arterial trunk. Classical stylohyoid syndrome is found after tonsillectomy and is characterized by pharyngeal, cervical, facial pain and headache. Stylo-carotid syndrome is the consequence of the pericarotid sympathetic fibres irritation and compression on the carotid artery. Clinical manifestations are found most frequently after head turning and neck compression. The diagnostic golden standard for styloid syndrome is 3D CT reconstruction. Sagital CT angiography has a leading role in the radiological diagnosis of the stylo-carotid syndrome. Differential diagnosis requires the differentiation of the styloid syndrome from numerous cranio-facio-cervical painful syndromes. If conservative treatment (analgesics, anticonvulsants, antidepressants, and local infiltration with steroids or anaesthetic agents has no effect, surgical treatment is applied. Styloid syndrome is underrepresented in neurological literature. The syndrome is considered important, because it is clinically similar to many other painful cranio-facial syndromes; it is difficult to be recognized, and the patient should be treated adequately.

[Beauty judgment: review of the literature].  

Science.gov (United States)

Esthetic judgments are surely subjective, but as surely, that does not preclude them being studied objectively through rigorous scientific methods. The factual basis of a science of esthetics is not to settle whether some person or image is "objectively beautiful" but rather to determine whether some representative set or sets of individuals judge or experience him/her/it as beautiful or unattractive. The aim of this paper is to review the definitional, theoretical and methodological aspects pertaining to the perception of facial/dental attractiveness by a group of representative individuals. The first part lays down the basic principles of the perception of facial/dental attractiveness: the perception involves a jury, a field of investigation and a test providing quantitative data; the following general determinants of beauty perception are reviewed: the average morphology, the judge's cultural background, the numerology, the judge's ethnical origin. Indirect determinants are the dentition, the osseous architecture and the muscular envelope. Some disruptive factors might alter the judges' facial perception. They might be qualified as either peripheral to the face or psycho-social factors. Peripheral factors include hair style and color, skin hue, wrinkles, lips color... Psycho-social factors cover the personality of the subject being evaluated, his/her intelligence or behavior. The second part deals specifically with the methodology used to determine facial attractiveness and to correlate this latter with a specific morphology. Typically such a study aims to determine average esthetic preferences for some set of visual displays among a particular jury, given a specific task to judge esthetic quality or qualities. The sample being studied, the displays, the jury or jurys, the rating procedure must all be specified prior to collecting data. A specific emphasis will be given to the rating process and the associated morphometrics, the ultimate goal being to discriminate morphologies judged as attractive among our patients. PMID:24685247

Full Text Available Objective : To review the trend of the study related to Leech therapy and to establish the hereafter direction for the study on Leech therapy. Methods : I reviewed and analyzed all the theses published in Domestic and Foreign research institution from 1990 to 2009. Results : The following results were obtained in this study. 1. Analyzed number of theses published, there was no significance per year. 2. Classified by theme of journal, journals related to surgery were most(41 journals, 75.92% among 54 kinds. 3. Classified by theses by research method and thesis types, case report accounted for nearly twothirds (52 pieces, 68.42% of all theses and consideration of document was next(9 pieces, 11.84%. 4. With the most case of venous congestion after plastic and reconstructive surgery(33 pieces, 63.46%, leech therapy was effective on illnesses such as haematoma, macroglossia, purpura, varicous vein, avulsion injury, neurovascular compression, diabetic neuropathy, penoscrotal oedema, buerger's disease, rheumatoid arthritis. 5. Two most appeared adverse effects were anemia and infection. Immediate blood transfusion was done for recovering anemia and prophylactic 3rd generation antibiotics to infection were emphasized in more than half of case reports. 6. All of consideration of documents was retrospective study of cases related leech therapy and 3 pieces of them emphasized prophyratic antibiotic treatment for preventing infection. 7. The study of clinical trail type started first in 2002 and osteoarthritis of knee and carpometacarpal joint were main target. As see above result, Leech therapy was effective cure and could be used in disease induced by venous congestion. And I think that it is necessary to perform additional study related to solution of problems about leech therapy and protocol for using in clinical practice.

Abortion care in Ghana: a critical review of the literature.  

Science.gov (United States)

The Government of Ghana has taken important steps to mitigate the impact of unsafe abortion. However, the expected decline in maternal deaths is yet to be realized. This literature review aims to present findings from empirical research directly related to abortion provision in Ghana and identify gaps for future research. A total of four (4) databases were searched with the keywords "Ghana and abortion" and hand review of reference lists was conducted. All abstracts were reviewed. The final include sample was 39 articles. Abortion-related complications represent a large component of admissions to gynecological wards in hospitals in Ghana as well as a large contributor to maternal mortality. Almost half of the included studies were hospital-based, mainly chart reviews. This review has identified gaps in the literature including: interviewing women who have sought unsafe abortions and with healthcare providers who may act as gatekeepers to women wishing to access safe abortion services.

Determinants, self-management strategies and interventions for hope in people with mental disorders: systematic search and narrative review.  

Science.gov (United States)

Developing a recovery focus in mental health services is a policy goal internationally, and hope is a central component of recovery. Yet determinants of hope of people with mental disorders are not well known, nor are strategies and interventions that increase hope. This study aims to systematically summarise the available evidence to fill four relevant knowledge gaps: (1) hope scales used in psychiatric research, (2) determinants of hope, (2) hope-fostering self-management strategies, and (3) interventions to increase hope for people with mental disorders. We conducted a systematic literature search in April 2011 and a narrative synthesis of publications including qualitative and quantitative studies. Results for the first time provide a comprehensive overview of existing evidence and identify important scientific knowledge gaps: (1) Hope scales used do slightly vary in focus but are overall comparable. (2) Most published research used cross-sectional designs resulting in a high number of potential determinants of hope. No studies prospectively investigated the influence of these determinants. (3) Hope fostering self-management strategies of people with mental disorders were described in qualitative studies only with experimental studies completely missing. (4) While some recovery oriented interventions were shown to increase hope as a secondary outcome, there are no successful interventions specifically aimed at increasing hope. This review provides the basis for both practical and research recommendations: The five most promising candidate interventions to improve hope in people with mental disorders are (i) collaborative strategies for illness management, (ii) fostering relationships, (iii) peer support, (iv) helping clients to assume control and to formulate and pursue realistic goals, and (v) specific interventions to support multiple positive factors such as self-esteem, self-efficacy, spirituality and well-being. These may serve to directly improve care and to develop theory-based models and testable interventions to improve hope in mental health as well as in allied fields. PMID:22240450

Science.gov (United States)

This narrative-descriptive review is about the safety/protection of hospitalized children who, due to their fragility, vulnerability and peculiar growth and development conditions need special attention from health professionals. This study aimed to identify knowledge production on safety, protection and violence to hospitalized children between 1997 and 2007. In total, 15 national and international articles were analyzed, using the key words: hospitalized child, safety, violence and nursing. This qualitative approach enabled the development of four categories: adverse occurrences; medication errors; notification of adverse occurrences; and safety of pediatric patients. Results indicate the need to develop strategies to reduce the probability of these events occurring during children's hospitalization, so that they do not suffer any problem neither violation of their fundamental rights.

Searching the scientific literature: implications for quantitative and qualitative reviews.  

Science.gov (United States)

Literature reviews are an essential step in the research process and are included in all empirical and review articles. Electronic databases are commonly used to gather this literature. However, several factors can affect the extent to which relevant articles are retrieved, influencing future research and conclusions drawn. The current project examined articles obtained by comparable search strategies in two electronic archives using an exemplar search to illustrate factors that authors should consider when designing their own search strategies. Specifically, literature searches were conducted in PsycINFO and PubMed targeting review articles on two exemplar disorders (bipolar disorder and attention deficit/hyperactivity disorder) and issues of classification and/or differential diagnosis. Articles were coded for relevance and characteristics of article content. The two search engines yielded significantly different proportions of relevant articles overall and by disorder. Keywords differed across search engines for the relevant articles identified. Based on these results, it is recommended that when gathering literature for review papers, multiple search engines should be used, and search syntax and strategies be tailored to the unique capabilities of particular engines. For meta-analyses and systematic reviews, authors may consider reporting the extent to which different archives or sources yielded relevant articles for their particular review. PMID:22819996

Public opinion about energy: a literature review  

Energy Technology Data Exchange (ETDEWEB)

A review and analysis of 115 surveys of the general population between 1973 and 1978 (before the Three Mile Island accident, sudden gasoline price increases, and spot gasoline shortages) are presented. The survey data are organized and analyzed according to a set of categories described in Chapter 2. The public's definition of the energy situation is the focus of Chapter 3. Chapter 4 describes public opinion concerning energy conservation pertaining to transportation and domestic energy use -- whether it is efficacious, how knowledgeable people are about conservation, whether they favor it, and whether they engage in it. Findings on the solar energy alternative are described in Chapter 5. Public opinion concerning more conventional sources of energy -- oil and natural gas, coal, and nuclear energy -- are discussed in Chapter 6. In Chapter 7, a summary of analytical findings by 10 major sociodemographic characteristics is presented. Chapter 8 describes analytical findings using various social-psychological variables. A summary is presented in Chapter 9.

A simple denitrification model? Literature review, sensitivity analysis, and application  

OpenAIRE

Denitrification is a complex process. In literature, this process is mostly described by a simplified process model. From a literature review, the consensus model describes the actual denitrification rate as being equal to some potential denitrification rate subsequently reduced by soil environmental conditions. Typically, potential denitrification is reduced by nitrate content, degree of saturation (water content) as a measure for anaerobic conditions, soil temperature, and possibly soil pH....

Revisão sistemática da acurácia dos testes diagnósticos: uma revisão narrativa / Systematic review of diagnostic tests accuracy: a narrative review  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: Portuguese Abstract in portuguese Este artigo tem o objetivo de realizar uma revisão narrativa sobre revisão sistemática da acurácia dos testes diagnósticos. Foi realizada busca na Cochrane Methodology Reviews (Cochrane Reviews of Diagnostic Test Accuracy), Medline e LILACS, bem como busca manual das listas de referências dos artigo [...] s incluídos na revisão. As estratégias de busca empregadas foram as seguintes, empregando-se títulos de assuntos e termos livres: 1. na Cochrane Methodology Reviews: accuracy study "Methodology" 2. Na Pubmed "Meta-Analysis "[Publication Type] AND "Evidence-Based Medicine"[Mesh]) AND "Sensitivity and Specificity"[Mesh]; 3. Na LILACS: (revisao sistematica) or "literatura de REVISAO como assunto" [Descritor de assunto] and (sistematica) or "SISTEMATICA" [Descritor de assunto] and (acuracia) or "SENSIBILIDADE e especificidade" [Descritor de assunto]. Em suma, a preparação e o planejamento metodológicos das revisões sistemáticas de testes diagnósticos é ulterior àqueles empregados nas revisões sistemáticas das intervenções terapêuticas. Há muitas fontes de heterogeneidade nos desenhos dos estudos de teste diagnóstico, o que dificulta muito a síntese - metanálise - dos seus resultados. Para contornar esse problema, existem atualmente normas, exigidas pelas principais revistas biomédicas, para a submissão de um manuscrito sobre testes diagnósticos. Abstract in english The aim of this study is to perform a narrative review of systematic reviews of diagnostic tests accuracy. We undertook a search using The Cochrane Methodology Reviews (Cochrane Reviews of Diagnostic Test Accuracy), Medline and LILACS up to October 2009. Reference lists of included studies were also [...] hand searched. The following search strategy was constructed by using a combination of subject headings and text words: 1. Cochrane Methodology Reviews: accuracy study "Methodology" 2. In Pubmed "Meta-Analysis" [Publication Type] AND "Evidence-Based Medicine" [Mesh]) AND "Sensitivity and Specificity" [Mesh] 3.

In summary, the methodological planning and preparation of systematic reviews of therapeutic interventions are prior to that used in systematic reviews of diagnostic tests accuracy. There are more sources of heterogeneity in design of diagnostic test studies, which impair the synthesis - meta-analysis - of the results. To work around this problem, there are currently uniform requirements for diagnostic test manuscripts submitted to leading biomedical journals.

Effects of vitamin D on parathyroid hormone and clinical outcomes in peritoneal dialysis: a narrative review.  

Science.gov (United States)

Vitamin D deficiency is very prevalent in dialysis and peritoneal dialysis (PD) patients show lower levels of cholecalciferol (25(OH)D3) than hemodialysis patients. We conducted a systematic narrative review to assess the effects of vitamin D therapy on control of secondary hyperparathyroidism and clinical outcomes induced by vitamin D pleiotropic effects. Medline database was searched for cohort and intervention studies reporting data on vitamin D (all sterols including synthetic analogs) and peritoneal dialysis without language restriction. Two authors independently extracted data. Twenty-nine observational and eleven interventional studies were identified for inclusion (1,036 subjects). PTH levels decreased in twenty-nine studies, increased in one study and remained stable in ten studies. Thirty-three studies analyzed the oral route for vitamin D administration, ten the intraperitoneal, one the subcutaneous and one the intravenous. A significant decrease of peritonitis risk was observed in two studies. Proteinuria decreased in four studies and remained stable in one study. Peritoneal protein loss decreased in one study and was stable in two studies. Studies on the therapeutic effects of vitamin D in PD are limited and describe small population samples. Moreover, vitamin D compounds do not consistently reduce PTH levels. The administration of active vitamin D in PD may have interesting pleiotropic effects such as decreasing proteinuria and peritoneal protein loss. According to these effects, vitamin D could help to preserve residual renal function and ensure efficient peritoneal membrane dialysance. PMID:25012237

The relationship between organizational culture and implementation of clinical practice guidelines: a narrative review.  

Science.gov (United States)

The context in which critical care providers work has been shown to be associated with adherence to recommendations of clinical practice guidelines (CPGs). Consideration of contextual factors such as organizational culture may therefore be important when implementing guidelines. Organizational culture has been defined simply as "how things are around here" and encompasses leadership, communication, teamwork, conflict resolution, and other domains. This narrative review highlights the results of recent quantitative and qualitative studies, including studies on adherence to nutrition guidelines in the critical care setting, which demonstrate that elements of organizational culture, such as leadership support, interprofessional collaboration, and shared beliefs about the utility of guidelines, influence adherence to guideline recommendations. Outside nutrition therapy, there is emerging evidence that strategies focusing on organizational change (eg, revision of professional roles, interdisciplinary teams, integrated care delivery, computer systems, and continuous quality improvement) can favorably influence professional performance and patient outcomes. Consequently, future interventions aimed at implementing nutrition guidelines should aim to measure and take into account organizational culture, in addition to considering the characteristics of the patient, provider, and guideline. Further high quality, multimethod studies are required to improve our understanding of how culture influences guideline implementation, and which organizational change strategies might be most effective in optimizing nutrition therapy.

A Systematic Review of Sexual Health Interventions for Adults: Narrative Evidence.  

Science.gov (United States)

Recent work has explored the intersection between sexual health (as construed by the World Health Organization and others) and public health domains of action in the United States of America. This article reports the narrative results of a systematic review of sexual health intervention effects on public health-relevant outcomes. To qualify, interventions had to be based on the principles (1) that sexual health is intrinsic to individuals and their overall health and (2) that relationships reflecting sexual health must be positive for all parties concerned. Outcomes were classed in domains: knowledge, attitudes, communication, health care use, sexual behavior, and adverse events. We summarized data from 58 studies (English language, adult populations, 1996-2011) by population (adults, parents, sexual minorities, vulnerable populations) across domains. Interventions were predominantly individual and small-group designs that addressed sexual behaviors (72%) and attitudes/norms (55%). They yielded positive effects in that 98% reported a positive finding in at least one domain; 50% also reported null effects. The most consistently positive effects on behaviors and adverse events were found for sexual minorities, vulnerable populations, and parental communication. Whether via direct action or through partnerships, incorporating principles from existing sexual health definitions in public health efforts may help improve sexual health. PMID:25406027

Integrating a Narrative Medicine Telephone Interview with Online Life Review Education for Cancer Patients: Lessons Learned and Future Directions  

Science.gov (United States)

We describe an online narrative and life review education program for cancer patients and the results of a small implementation test to inform future directions for further program development and full-scale evaluation research. The intervention combined three types of psycho-oncology narrative interventions that have been shown to help patients address emotional and existential issues: 1) a physician-led dignity-enhancing telephone interview to elicit the life narrative and delivery of an edited life manuscript, 2) life review education, delivered via 3) a website self-directed instructional materials and expert consultation to help people revise and share their story. Eleven cancer patients tested the intervention and provided feedback in an in-depth exit interview. While everyone said telling and receiving the edited story manuscript was helpful and meaningful, only people with high death salience and prior computer experience used the web tools to enhance and share their story. Computer users prodded us to provide more sophisticated tools and older (>70 years) users needed more staff and family support. We conclude that combining a telephone expert-led interview with online life review education can extend access to integrative oncology services, are most feasible for computer-savvy patients with advanced cancer, and must use platforms that allow patients to upload files and invite their social network.

Fahr's syndrome: literature review of current evidence.  

Science.gov (United States)

Fahr's disease or Fahr's syndrome is a rare, neurological disorder characterized by abnormal calcified deposits in basal ganglia and cerebral cortex. Calcified deposits are made up of calcium carbonate and calcium phosphate, and are commonly located in the Basal Ganglia, Thalamus, Hippocampus, Cerebral cortex, Cerebellar Subcortical white matter and Dentate Nucleus. Molecular genetics of this disease haven't been studied extensively; hence evidence at the molecular and genetic level is limited. Fahr's disease commonly affects young to middle aged adults. Etiology of this syndrome does not identify a specific agent but associations with a number of conditions have been noted; most common of which are endocrine disorders, mitochondrial myopathies, dermatological abnormalities and infectious diseases. Clinical manifestations of this disease incorporate a wide variety of symptoms, ranging from neurological symptoms of extrapyramidal system to neuropsychiatric abnormalities of memory and concentration to movement disorders including Parkinsonism, chorea and tremors amongst others. Diagnostic criteria for this disease has been formulated after modifications from previous evidence and can be stated briefly, it consist of bilateral calcification of basal ganglia, progressive neurologic dysfunction, absence of biochemical abnormalities, absence of an infectious, traumatic or toxic cause and a significant family history. Imaging modalities for the diagnosis include CT, MRI, and plain radiography of skull. Other investigations include blood and urine testing for hematologic and biochemical indices. Disease is as yet incurable but management and treatment strategies mainly focus on symptomatic relief and eradication of causative factors; however certain evidence is present to suggest that early diagnosis and treatment can reverse the calcification process leading to complete recovery of mental functions. Families with a known history of Fahr's disease should be counseled prior to conception so that the birth of affected babies can be prevented. This review was written with the aim to remark on the current substantial evidence surrounding this disease. PMID:24098952

Engaging people who use drugs in policy and program development: A review of the literature  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Health policies and programs are increasingly being driven by people from the community to more effectively address their needs. While a large body of evidence supports peer engagement in the context of policy and program development for various populations, little is known about this form of engagement among people who use drugs (PWUD. Therefore, a narrative literature review was undertaken to provide an overview of this topic. Searches of PubMed and Academic Search Premier databases covering 1995–2010 were conducted to identify articles assessing peer engagement in policy and program development. In total, 19 articles were included for review. Our findings indicate that PWUD face many challenges that restrict their ability to engage with public health professionals and policy makers, including the high levels of stigma and discrimination that persist among this population. Although the literature shows that many international organizations are recommending the involvement of PWUD in policy and program development, our findings revealed a lack of published data on the implementation of these efforts. Gaps in the current evidence highlight the need for additional research to explore and document the engagement of PWUD in the areas of policy and program development. Further, efforts to minimize stigmatizing barriers associated with illicit drug use are urgently needed to improve the engagement of PWUD in decision making processes.

Is there an association between low dose aspirin and anemia (without overt bleeding?: narrative review  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Overt bleeding associated with low dose aspirin (LDA is well-recognized, little attention is given to the possibility of association between LDA and occult bleeding, although this is known to occur in healthy volunteers. LDA is used increasingly in primary and secondary prevention of a number of medical conditions, many of which are common in older people, as is anemia. Anemia in older people is associated with adverse outcomes including disability, morbidity and mortality. The purpose of this study was to review the evidence that LDA might cause anemia without overt bleeding. Methods An extensive narrative review was carried out. Electronic searching (including database links and reference lists of reports were used to identify studies reporting on use of aspirin ?325 mg/day and anemia or change in hemoglobin (Hb without overt bleeding. Data were extracted from reports of trials, adverse drug reactions (ADRs and prevalence studies of adults aged ?18 years, published since 1980. Results There are few relevant data, with considerable heterogeneity among trial designs, duration, and patient characteristics in studies of LDA. In five randomised trials (n = 5879 in (mostly secondary prevention, the majority of patients were men without peptic ulcer disease aged 50-70 years and no consistent association between LDA and change in Hb was found. In two smaller studies (n = 609 of primary prevention in healthy patients aged ?70 years, there was a small but statistically significant fall in Hb with LDA. Observational studies, and data from trials in which use of LDA was not a primary focus of the study, were inconclusive. Conclusions It is not clear whether there is an association between LDA and anemia in the absence of overt bleeding, but there may be an association between LDA and fall in Hb in (a subset of older patients. The available evidence has significant limitations, which are discussed; studies including more older patients, and publication of individual patient data, would help clarify this important matter.

Literature search, review, and compilation of data for chemical and radiochemical sensors: Task 1 report  

Energy Technology Data Exchange (ETDEWEB)

During the next several decades, the US Department of Energy is expected to spend tens of billions of dollars in the characterization, cleanup, and monitoring of DOE`s current and former installations that have various degrees of soil and groundwater contamination made up of both hazardous and mixed wastes. Each of these phases will require site surveys to determine type and quantity of hazardous and mixed wastes. It is generally recognized that these required survey and monitoring efforts cannot be performed using traditional chemistry methods based on laboratory evaluation of samples from the field. For that reason, a tremendous push during the past decade or so has been made on research and development of sensors. This report contains the results of an extensive literature search on sensors that are used or have applicability in environmental and waste management. While restricting the search to a relatively small part of the total chemistry spectrum, a sizable body of reference material is included. Results are presented in tabular form for general references obtained from data base searches, as narrative reviews of relevant chapters from proceedings, as book reviews, and as reviews of journal articles with particular relevance to the review. Four broad sensor types are covered: electrochemical processes, piezoelectric devices, fiber optics, and radiochemical processes. The topics of surface chemistry processes and biosensors are not treated separately because they often are an adjunct to one of the four sensors listed. About 1,000 tabular entries are listed, including selected journal articles, reviews of conference/meeting proceedings, and books. Literature to about mid-1992 is covered.

The experience of living with chronic heart failure: a narrative review of qualitative studies  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Chronic heart failure (CHF is the leading cause of all hospitalisations and readmissions in older people, accounting for a large proportion of developed countries' national health care expenditure. CHF can severely affect people's quality of life by reducing their independence and ability to undertake certain activities of daily living, as well as affecting their psychosocial and economic capacity. This paper reports the findings of a systematic narrative review of qualitative studies concerning people's experience of living with CHF, aiming to develop a wide-ranging understanding of what is known about the patient experience. Methods We searched eight relevant electronic databases using the terms based on the diagnosis of 'chronic heart failure', 'heart failure' and 'congestive heart failure' and qualitative methods, with restrictions to the years 1990-May 2008. We also used snowballing, hand searching and the expert knowledge of the research team to ensure all relevant papers were included in the review. Of 65 papers collected less than half (n = 30 were found relevant for this review. These papers were subsequently summarised and entered into QSR NVivo7 for data management and analysis. Results The review has identified the most prominent impacts of CHF on a person's everyday life including social isolation, living in fear and losing a sense of control. It has also identified common strategies through which patients with CHF manage their illness such as sharing experiences and burdens with others and being flexible to changing circumstances. Finally, there are multiple factors that commonly impact on patients' self care and self-management in the disease trajectory including knowledge, understanding and health service encounters. These health service encounters encompass access, continuity and quality of care, co-morbid conditions, and personal relationships. Conclusions The core and sub-concepts identified within this study provide health professionals, service providers, policy makers and educators with broad insights into common elements of people's experiences of CHF and potential options for improving their health and wellbeing. Future studies should focus on building a comprehensive picture of CHF through examination of differences between genders, and differences within age groups, socioeconomic groups and cultural groups.

Role modeling in undergraduate nursing education: an integrative literature review.  

Science.gov (United States)

The transition of nursing education from the hospital setting to the university sector over recent decades has opened dialog about who is guiding the development of nursing students' professional identity. In addition, there is ongoing debate over real or perceived gaps between nursing student learning in the university and the clinical area, how this translates into professional behaviors and how well students make the transition between the two settings. This paper presents the findings of an integrative literature review into the topic of role modeling in undergraduate nursing education. This review was conducted to identify and appraise research findings about role modeling of professional behaviors for undergraduate nursing students. Literature reviewed from 2000 onwards assesses what is currently known about role modeling of undergraduate nursing students. A systematic search of the databases of CINAHL, Scopus and PubMed from 2000 onwards resulted in the selection of 33 articles for deeper analysis. Two clear themes emerged from the literature, the first relating to nurse clinicians as role models for students during clinical placements and the second relating to nurse academics as role models in the academic setting. Findings from this integrative literature review show an imbalance in the recognition of the role modeling of professional behaviors in the clinical versus the academic setting. Nurses in academic settings have more contact with the students over their period of study and as such, the significance of nurse academics as student role models requires further investigation.

Taking Stock of Project Value Creation: A Structured Literature Review  

DEFF Research Database (Denmark)

This paper presents the outcome of a literature review through classifying and analyzing 59 publications in project value creation literature. The analysis led to five distinct categories: Benefit Realization Management (BRM) and techniques, broad value perspective, value time frame, engineering requirements and product development. These five categories cover a wide selection of value creation literature in project contexts. The project types reported in empirical studies are mainly IS/IT and construction and a variety of other types such as R&D and strategy implementation. The literature dates back to the mid-1990s while the majority of the publications on value creation have been published since 2008. The value creation focus, or value-centric view, is thus rather recent and the research area is still developing.

Preventing stroke: a narrative review of community interventions for improving hypertension control in black adults.  

Science.gov (United States)

Incidence rates for stroke and hypertension are higher in black ethnic groups of African descent in the USA and UK than in white groups, suggesting a need for targeted intervention. We conduct a narrative review of published research evidence on community interventions to manage hypertension among black ethnic groups, and explore the concept of cultural sensitivity in these interventions. Data sources comprised computer-aided searches of published studies over the years 1981 to March 2006, on community strategies for improving hypertension control targeting black groups, and further references from these articles. Twenty-seven relevant studies were identified. Health education was associated with improvements in knowledge about hypertension, while education combined with individualised support for patients to self-manage hypertension, including goal setting and monitoring to enhance patient self-management of hypertension, and family support in managing hypertension were associated with reductions in blood pressure levels and improvements in blood pressure control. Collaboration with black communities, using local or minority ethnic staff, conducting preliminary research with target groups to investigate perceptions and canvass ideas for the intervention design were common methods assumed to achieve cultural sensitivity. Studies, however, provided insufficient robust evidence of the effectiveness of these strategies in terms of quantifiable outcomes, although this criterion is contested, with social justice arguments being offered instead. Implicit assumptions about homogeneity and shared interests within the 'community', and representation of 'community' views have implications for the effectiveness of interventions. These findings highlight areas for the future development of interventions to reduce hypertension rates in black groups, and factors that need to be robustly investigated and explicitly addressed in intervention design.

Injury associated with methamphetamine use: A review of the literature  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract This paper reviews the literature exploring issues around methamphetamine and injury. There was a paucity of peer reviewed quantitative research and a lack of large scale epidemiological studies. Further sources described cases and others described injury risk as part of an overall review of methamphetamine misuse. Thus, a number of limitations and potential biases exist within the literature. The main areas where associations were noted or extrapolated with methamphetamine use and injury were around driving and violence. Other associations with injury related to methamphetamine manufacture. There was also circumstantial evidence for third party injury (that is injury to those not specifically involved in drug use or drug manufacture; however, the available data are inadequate to confirm these associations/risks.

Understanding attractiveness in business relationships - A complete literature review  

DEFF Research Database (Denmark)

The concept of attraction has received surprisingly little attention within business relationship research. Yet, recently, more and more authors have argued that attraction may contribute to the motivation and willingness of a buyer and supplier to engage in and develop a business relationship. However, the concept of attraction is relatively new and there have been diverse interpretations of it. This literature review collates those interpretations with the aim of enhancing current understanding and creating fundamental knowledge of the current streams of literature on the concept. In examining how the concept has been investigated, the paper aims to establish the direction that the understanding and use of the concept of attractiveness may take in the future in the context of business research. The literature review indicates that attraction has been used in three research areas to explain or resolve a particular construct: 1) attraction in the development of buyer-supplier relationships, 2) customer attractiveness to suppliers, and 3) attractiveness in portfolio and key account management. This literature review contributes to the understanding of how knowledge of the power of attraction could enrich the theory and practice of business relationships. (C) 2012 Elsevier Inc.

Primary anetoderma and antiphospholipid antibodies--review of the literature.  

Science.gov (United States)

Primary anetoderma (PA) is a rare elastolytic disorder that develops in clinically normal skin or following a nonspecific inflammatory process. The old literature contains numerous reports of the association between PA and lupus eryhtematosus, although the relationship has not been clearly established. In recent years, there has been a growing body of literature linking PA with a wide range of immunologic abnormalities, the most common of which is the presence of antiphospholipid antibodies, with or without antiphospholipid syndrome. The present review summarizes the literature, from the early descriptions pointing toward an immunologic basis of PA and up to the present recognition that PA is a cutaneous sign for autoimmune disorders, in general, and the presence of antiphospholipid in particular.

The effects of transcutaneous electrical nerve stimulation on tissue repair: A literature review  

Science.gov (United States)

BACKGROUND: Transcutaneous electrical nerve stimulation (TENS) consists of a generic application of low-frequency, pulsed electrical currents transmitted by electrodes through the skin surface. It is a therapeutic modality that is nonpharmacological, noninvasive, inexpensive, easy to use and widely applied in clinical practice. OBJECTIVE: To narratively review the scientific evidence of the effects of TENS on tissue repair with respect to wound healing, skin flap viability and tendinous repair. METHODS: The study was conducted using the MEDLINE, Lilacs and Scielo databases, without limit to the period of publication, and was completed in November 2011. Inclusion criteria were randomized or nonrandomized, controlled or noncontrolled clinical trials, and experimental trials involving rats subjected to TENS for tissue repair. RESULTS: Thirty articles on tissue repair were found and, among these, 14 reported on wound healing, 14 reported on skin flaps and two analyzed tedinous repair. DISCUSSION: It was suggested that TENS stimulates skin wound healing and tendon repair, as well as the viability of random skin flaps. Such effects may be due to the release of substance P and calcitonin gene-related peptide, which would increase blood flow and, consequently, hasten the events leading to tissue repair. CONCLUSIONS: Based on the scientific evidence regarding the effects of TENS on tissue repair, the findings of the present literature review were inconclusive because data from the randomized controlled clinical trials were insufficient to confirm such effects.

Single-cone obturation technique: a literature review  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction: The technique of single-cone obturation is a technique that uses only the master cone. There have been an increase in its use, especially by employing larger cones with larger taper sizes that best match the geometry of rotary nickel-titanium systems (NiTi, not requiring the use of accessory cones, thus reducing the time spent in endodontic obturation. Objective: To review the literature on this technique and to compare it with other existing techniques, as well as to elucidate its advantages and disadvantages. Literature review: The single-cone obturation technique enables an easier and faster endodontic obturation. However, regarding to the aspects such as the obturation quality, apical microleakage and bacterial penetration, this technique is similar to or lower than others. Conclusion: This technique has the advantage of saving time during the filling of the root canal. However, further studies are necessary to evaluate its prognosis, especially in canals with complex anatomy.

A Literature Review on Organizational Commitment – A Comprehensive Summary  

Directory of Open Access Journals (Sweden)

Full Text Available The paper encapsulates the evolution of the concept of organizational commitment, and its constructs. It focuses and analyses the literature findings of organizational commitments over the last five decades. It categorizes the approaches into six broad eras, each era being an extension and modification over the preceding ones. This review paper brings to the fore the theories that have emerged in the body of knowledge regarding commitment in organizations in a chronological order, starting from the side bet theory to the more recent multiple commitment approach. The gaps in the theories proposed have been identified and reviewed critically. It is difficult to conceptualize and measure organizational commitment as it encompasses a vast and highly diverse body of knowledge. Due to this it becomes difficult to interpret and conclude from the existing bodies of literature. The paper also highlights the importance of recognizing the individual/employee?s perspective towards organizational commitment.

Moral distress experienced by nurses: A quantitative literature review.  

Science.gov (United States)

Nurses are frequently confronted with ethical dilemmas in their nursing practice. As a consequence, nurses report experiencing moral distress. The aim of this review was to synthesize the available quantitative evidence in the literature on moral distress experienced by nurses. We appraised 19 articles published between January 1984 and December 2011. This review revealed that many nurses experience moral distress associated with difficult care situations and feel burnout, which can have an impact on their professional position. Further research is required to examine worksite strategies to support nurses in these situations and to develop coping strategies for dealing with moral distress. PMID:24091351

Gender, Nationality and Leadership Style: A Literature Review  

Directory of Open Access Journals (Sweden)

Full Text Available The aim of this paper is to review research available on gender and nationality as determinants of leadershipstyle, with special focus on top leaders/managers. The paper is based on a systematic literature review. Thesystematic literature search resulted in 27 papers, that were grouped in five categories: 1 Leaders’characteristics, behavior and style, 2 Perception regarding leaders, their traits and leadership styles, 3Women’s barriers towards leader positions, 4 Leadership outcome/results, 5 Effect of research methods onleader evaluation. Questionnaires were the most used research method in the reviewed studies. Almost half ofthe papers focus on the US, while the rest deal with African, Asian, and European countries. In this review, wefound that women and men have a very similar perception of a successful manager. However, women and mendisplay differences in their leader behavior and characteristics, and way of leading. “Results/outcomes” of sucha leadership can differ. The review shows, furthermore, that a glass ceiling and other barriers for women do stillexist.The paper ends by identifying the needs for further research in the study area.

Chemotherapy education for patients with cancer: a literature review.  

Science.gov (United States)

A literature review was conducted to determine the best way to provide chemotherapy education to patients. Sixteen articles that employed various teaching methods (e.g., video recordings, in-person class) were identified. Some educational methods have been proven to decrease anxiety, which allows patients to retain more information. Many ways can be used to provide chemotherapy education, and no method has been proven to be significantly more effective than another. Maximum retention is largely based on patient preference.

Shared Communications: Volume 1. A Summary and Literature Review  

Energy Technology Data Exchange (ETDEWEB)

This paper provides a review of examples from the literature of shared communication resources and of agencies and/or organizations that share communication resources. The primary emphasis is on rural, intelligent transportation system communications involving transit. Citations will not be limited, however, to rural activities, or to ITS implementation, or even to transit. In addition, the term ''communication'' will be broadly applied to include all information resources. Literature references to issues that contribute to both successful and failed efforts at sharing communication resources are reviewed. The findings of this literature review indicate that: (1) The most frequently shared communication resources are information/data resources, (2) Telecommunications infrastructure and technologies are the next most frequently shared resources, (3) When resources are successfully shared, all parties benefit, (4) A few unsuccessful attempts of sharing resources have been recorded, along with lessons learned, (5) Impediments to sharing include security issues, concerns over system availability and reliability, service quality and performance, and institutional barriers, (6) Advantages of sharing include financial benefits to agencies from using shared resources and benefits to the public in terms of congestion mitigation, information transfer (e.g., traveler information systems), mobility (e.g., welfare-to-work paratransit), and safety (e.g., speed of incident response, incident avoidance), (7) Technology-based solutions exist to address technology-based concerns, and (8) Institutional issues can be addressed through leadership, enhanced knowledge and skills, open communication, responsiveness, and attractive pricing structures.

Mobile phone text messaging to reduce alcohol and tobacco use in young people – a narrative review  

Directory of Open Access Journals (Sweden)

Full Text Available Severin Haug Swiss Research Institute for Public Health and Addiction at Zurich University, Zurich, Switzerland Background: Alcohol and tobacco use are major causes of the disease burden in most countries of the world. Mobile phone text messaging is very popular among adolescents and young adults and has the potential to deliver individualized information to large population groups at low costs. Objective: To provide a narrative review on studies testing the appropriateness and effectiveness of text messaging-based programs to reduce alcohol and tobacco use in young people. Results: Two published studies on text message-based programs for the reduction of problem drinking and two studies on programs for enhancing smoking cessation were identified. A US-American pilot experimental study tested the feasibility and initial efficacy of a text messaging-based assessment and brief intervention among young adults identified during their emergency department visit with hazardous drinking. It demonstrated the feasibility of the text messaging-based program to collect drinking data in young adults after emergency department discharge. A Swiss pre–post study tested the appropriateness and initial effectiveness of a combined, individually tailored web- and text messaging (SMS-based program to reduce problem drinking in vocational school students. It provided evidence for the appropriateness of the intervention and initial evidence for its efficacy to reduce problem drinking. One of the two studies addressing smoking cessation was a US-American pilot randomized controlled trial. Participants were recruited via online advertisements and received text messages tailored according to their quitting stage. The intervention significantly affected self-reported quitting rates at 4 weeks but not at 3 months after the quit date. Within a cluster-randomized controlled trial conducted in Switzerland, smoking students were proactively recruited within vocational school classes and received text messages tailored to demographic and smoking-related variables. The program was accepted very well by the target group. It did not affect smoking abstinence rates at 6-months follow-up but resulted in significant lower cigarette consumption. Conclusion: First results on the appropriateness and short-term efficacy of text message-based interventions to reduce tobacco and alcohol use in young people are promising; however, further adequately powered trials are needed to confirm these initial results and to test the longer-term efficacy of these programs. Keywords: text messaging, alcohol, tobacco, young people

Immunomodulatory dietary polysaccharides: a systematic review of the literature  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background A large body of literature suggests that certain polysaccharides affect immune system function. Much of this literature, however, consists of in vitro studies or studies in which polysaccharides were injected. Their immunologic effects following oral administration is less clear. The purpose of this systematic review was to consolidate and evaluate the available data regarding the specific immunologic effects of dietary polysaccharides. Methods Studies were identified by conducting PubMed and Google Scholar electronic searches and through reviews of polysaccharide article bibliographies. Only articles published in English were included in this review. Two researchers reviewed data on study design, control, sample size, results, and nature of outcome measures. Subsequent searches were conducted to gather information about polysaccharide safety, structure and composition, and disposition. Results We found 62 publications reporting statistically significant effects of orally ingested glucans, pectins, heteroglycans, glucomannans, fucoidans, galactomannans, arabinogalactans and mixed polysaccharide products in rodents. Fifteen controlled human studies reported that oral glucans, arabinogalactans, heteroglycans, and fucoidans exerted significant effects. Although some studies investigated anti-inflammatory effects, most studies investigated the ability of oral polysaccharides to stimulate the immune system. These studies, as well as safety and toxicity studies, suggest that these polysaccharide products appear to be largely well-tolerated. Conclusions Taken as a whole, the oral polysaccharide literature is highly heterogenous and is not sufficient to support broad product structure/function generalizations. Numerous dietary polysaccharides, particularly glucans, appear to elicit diverse immunomodulatory effects in numerous animal tissues, including the blood, GI tract and spleen. Glucan extracts from the Trametes versicolor mushroom improved survival and immune function in human RCTs of cancer patients; glucans, arabinogalactans and fucoidans elicited immunomodulatory effects in controlled studies of healthy adults and patients with canker sores and seasonal allergies. This review provides a foundation that can serve to guide future research on immune modulation by well-characterized polysaccharide compounds.

[Current status of the prevention and treatment of stoma complications. A narrative review].  

Science.gov (United States)

The aim of our study was to perform a review of the literature to assess the results of prevention and treatment of stoma complications. Medline, EMBASE medical database and the Cochrane Library were searched up to December 2012. Stomal complications are prevalent and associated with a worse quality of life and increased health-economic burdens. The most common complications are attributed to stoma construction. Attention to the finer technical points performed by experienced surgeons reduces morbidity. The use of mesh reduces the risk of parastomal hernia and recurrence rates in hernia repair. Preoperative stoma site marking and postoperative care by a stomatherapist are crucial for the patients' successful adaption, improving quality of life, promoting their independence and reducing the rates of complications.

LCAs of petrol and diesel - A literature review  

Energy Technology Data Exchange (ETDEWEB)

Many life cycle assessment (LCA) studies have investigated the environmental impact of using biofuel in transportation compared with fossil fuels. Since these studies often use standard values for the fossil fuel reference scenario, there is a need for a thorough review of published data on fossil fuel use in transportation. This study reviewed the available literature regarding greenhouse gas (GHG) emissions and energy balances in petrol and diesel use and examined possible causes for the differences reported in the literature. This included differences connected to the LCA methodology itself, but also those resulting from technical and economic effects. Thirteen studies were reviewed in order to establish the level of GHG emissions and energy use in the well-to-tank perspective and, where possible, in the entire well-to-wheel perspective. The studies used different input data, allocation methods and system boundaries, but the results fell within a narrow range, since the energy content of the fuels on a tank-to-wheel basis differed only slightly, while the use phase represents most GHG emissions and energy usage in fuel life cycles. All studies reviewed reported GHG emissions values that exceeded the reference value of 83.8 g CO{sub 2}-eq/MJ fuel suggested in the EU Renewable Energy Directive.

When All Children Comprehend: Increasing the External Validity of Narrative Comprehension Development Research  

Directory of Open Access Journals (Sweden)

Full Text Available Narratives, also called stories, can be found in conversations, children’s play interactions, reading material, and television programs. From infancy to adulthood, narrative comprehension processes interpret events and inform our understanding of physical and social environments. These processes have been extensively studied to ascertain the multifaceted nature of narrative comprehension. From this research we know that three overlapping processes (i.e., knowledge integration, goal structure understanding, and causal inference generation proposed by the constructionist paradigm are necessary for narrative comprehension, narrative comprehension has a predictive relationship with children’s later reading performance, and comprehension processes are generalizable to other contexts. Much of the previous research has emphasized internal and predictive validity; thus, limiting the generalizability of previous findings. We are concerned these limitations may be excluding underrepresented populations from benefits and implications identified by early comprehension processes research. This review identifies gaps in extant literature regarding external validity and argues for increased emphasis on externally valid research. We highlight limited research on narrative comprehension processes in children from low-income and minority populations, and argue for changes in comprehension assessments. Specifically, we argue both on- and off-line assessments should be used across various narrative types (e.g., picture books, televised narratives with traditionally underserved and underrepresented populations. We propose increasing the generalizability narrative comprehension processes research can inform persistent reading achievement gaps, and have practical implications for how children learn from narratives.

Health effects and wind turbines: A review of the literature  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Wind power has been harnessed as a source of power around the world. Debate is ongoing with respect to the relationship between reported health effects and wind turbines, specifically in terms of audible and inaudible noise. As a result, minimum setback distances have been established world-wide to reduce or avoid potential complaints from, or potential effects to, people living in proximity to wind turbines. People interested in this debate turn to two sources of information to make informed decisions: scientific peer-reviewed studies published in scientific journals and the popular literature and internet. Methods The purpose of this paper is to review the peer-reviewed scientific literature, government agency reports, and the most prominent information found in the popular literature. Combinations of key words were entered into the Thomson Reuters Web of KnowledgeSM and the internet search engine Google. The review was conducted in the spirit of the evaluation process outlined in the Cochrane Handbook for Systematic Reviews of Interventions. Results Conclusions of the peer reviewed literature differ in some ways from those in the popular literature. In peer reviewed studies, wind turbine annoyance has been statistically associated with wind turbine noise, but found to be more strongly related to visual impact, attitude to wind turbines and sensitivity to noise. To date, no peer reviewed articles demonstrate a direct causal link between people living in proximity to modern wind turbines, the noise they emit and resulting physiological health effects. If anything, reported health effects are likely attributed to a number of environmental stressors that result in an annoyed/stressed state in a segment of the population. In the popular literature, self-reported health outcomes are related to distance from turbines and the claim is made that infrasound is the causative factor for the reported effects, even though sound pressure levels are not measured. Conclusions What both types of studies have in common is the conclusion that wind turbines can be a source of annoyance for some people. The difference between both types is the reason for annoyance. While it is acknowledged that noise from wind turbines can be annoying to some and associated with some reported health effects (e.g., sleep disturbance, especially when found at sound pressure levels greater than 40 db(A, given that annoyance appears to be more strongly related to visual cues and attitude than to noise itself, self reported health effects of people living near wind turbines are more likely attributed to physical manifestation from an annoyed state than from wind turbines themselves. In other words, it appears that it is the change in the environment that is associated with reported health effects and not a turbine-specific variable like audible noise or infrasound. Regardless of its cause, a certain level of annoyance in a population can be expected (as with any number of projects that change the local environment and the acceptable level is a policy decision to be made by elected officials and their government representatives where the benefits of wind power are weighted against their cons. Assessing the effects of wind turbines on human health is an emerging field and conducting further research into the effects of wind turbines (and environmental changes on human health, emotional and physical, is warranted.

Landslide Susceptibility Statistical Methods: A Critical and Systematic Literature Review  

Science.gov (United States)

Landslide susceptibility assessment, the subject of this systematic review, is aimed at understanding the spatial probability of slope failures under a set of geomorphological and environmental conditions. It is estimated that about 375 landslides that occur globally each year are fatal, with around 4600 people killed per year. Past studies have brought out the increasing cost of landslide damages which primarily can be attributed to human occupation and increased human activities in the vulnerable environments. Many scientists, to evaluate and reduce landslide risk, have made an effort to efficiently map landslide susceptibility using different statistical methods. In this paper, we do a critical and systematic landslide susceptibility literature review, in terms of the different statistical methods used. For each of a broad set of studies reviewed we note: (i) study geography region and areal extent, (ii) landslide types, (iii) inventory type and temporal period covered, (iv) mapping technique (v) thematic variables used (vi) statistical models, (vii) assessment of model skill, (viii) uncertainty assessment methods, (ix) validation methods. We then pulled out broad trends within our review of landslide susceptibility, particularly regarding the statistical methods. We found that the most common statistical methods used in the study of landslide susceptibility include logistic regression, artificial neural network, discriminant analysis and weight of evidence. Although most of the studies we reviewed assessed the model skill, very few assessed model uncertainty. In terms of geographic extent, the largest number of landslide susceptibility zonations were in Turkey, Korea, Spain, Italy and Malaysia. However, there are also many landslides and fatalities in other localities, particularly India, China, Philippines, Nepal and Indonesia, Guatemala, and Pakistan, where there are much fewer landslide susceptibility studies available in the peer-review literature. This raises some concern that existing studies do not always cover all the regions globally that currently experience landslides and landslide fatalities.

The impact of infertility on sexuality: A literature review  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Most studies address medical treatment of infertility and psychosocial outcomes caused by infertility-related stress, but few studies examine the infertility’s impact on sexuality.Aim: A literature review was conducted to answer the questions: 1 How is sexual self concept impacted in infertile individuals and their partners? 2 Does infertility have a negative impact on sexual relationships? 3 Is sexual function affected by infertility? In answering these questions, we may develop a better understanding of sexuality in the context of infertility, and thus better inform infertility management. Ultimately the aim is to improve the quality of life for infertile couples.Method: A literature search was conducted for publications from 1990 to 2011 via the electronic databases PubMed, PsycInfo and Scopus, which focused on sexuality in infertile subjects or couples.Results: In this review, all studies were descriptive quantitative studies which mapped the different aspects of sexuality in the context of infertility. The results suggested that infertility and its treatment approaches for fertilisationcould lead to changes in sexual self-esteem, sexual relationship and sexual function.Conclusion: The literature substantiated that many infertile subjects experienced trouble in various aspects of sexuality. However, further research should examine the reciprocal relations between sexual self concept, sexual relationship and sexual function in the context of infertility. How these changes affect the partners of infertile subjects should also be addressed.

Medical humanities in healthcare education in Italy: a literature review  

Scientific Electronic Library Online (English)

Full Text Available SciELO Public Health | Language: English Abstract in english OBJECTIVE. The introduction of medical humanities (MH) in undergraduate medical education in Italy has been an issue of debate since the 90's and few years later it was extended to other healthcare degrees. The aims of this Italian literature review, after considering the international scene, are: t [...] o evaluate the extent to which the interest in this subject has gradually developed throughout the country; which professional groups have contributed to the debate; to identify which theoretical constructs led to the introduction of MH in undergraduate medical education; to identify whether a clear and shared definition of MH exists in Italian literature; to verify what kinds of MH experiences have been accomplished in Italy. MATERIALS AND METHODS. A comprehensive literature search was conducted, including electronic databases, bibliographies, manual sorting of articles in paper format, congress proceedings. RESULTS. The analysis of the chosen articles underlines that, however limited, Italian literature does not present a very different picture from the international scene. It emerges that teaching MH is believed to be an important feature in undergraduate education of healthcare professionals who intend to propose a bio-psychological-social approach to care, in spite of the difficulty to measure its short and long term effectiveness. The lack of a multidisciplinary, multi-professional approach is also evident. CONCLUSION. Further research aiming to implement the quantity and quality of MH studies in the curricula of undergraduate healthcare education is desirable.

Can local muscles augment stability in the hip? A narrative literature review.  

Science.gov (United States)

Hip pain and dysfunction are increasingly recognised as important causes of morbidity in younger and older adults. Pathology compromising the passive stability of the hip joint, including acetabular labral injury, may lead to increased femoral head translation, greater joint contact pressures and ultimately degenerative hip disease. Activation of hip muscles may play an important role in augmenting the stability in the normal and the passively unstable hip. Research at other joints suggests that the local, rather than global, muscles are well suited to provide subtle joint compression, limiting translation, with minimal metabolic cost. Based on the known characteristics of local muscles and the limited research available on hip muscles, it is proposed that the local hip muscles; quadratus femoris, gluteus minimus, gemelli, obturator internus and externus, iliocapsularis and the deep fibres of iliopsoas, may be primary stabilisers of the hip joint. Interventions aimed at restoring isolated neuromuscular function of the primary hip stabilisers may be considered when treating people with passive hip instability prior to commencing global muscle rehabilitation. Finally, further research is needed to investigate the potential association between function of the hip muscles (including muscles likely to have a role in stabilising the hip) and hip pathology affecting hip stability such as acetabular labral lesions.

Coral reef aorta, emergency surgical: case report and literature review.  

Science.gov (United States)

Coral reef aorta is described as an uncommon entity characterized by the presence of coarse calcifications, which are developed in the visceral aorta. These calcifications grow toward the lumen of the artery and can result in significant stenosis, so that causing malperfusion of the lower limbs, visceral ischemia or hypertension secondary to renal involvement. We report here a case of a 54-year-old patient with coral reef aorta and symptomatic. The clinical presentation of the patient required the surgical approach. A review of literature in major databases was conducted to compare health-related aspects of the disease presentation and management. Coral reef aorta should be considered as the diagnosis for patients with visceral and limbs ischemia. The approach in our case was consistent with other studies previously published in the literature. PMID:25003933

Laparoscopic distal pancreatectomy: Up-to-date and literature review  

Directory of Open Access Journals (Sweden)

Full Text Available Pancreatic surgery represents one of the most challenging areas in digestive surgery. In recent years, an increasing number of laparoscopic pancreatic procedures have been performed and laparoscopic distal pancreatectomy (LDP has gained world-wide acceptance because it does not require anastomosis or other reconstruction. To date, English literature reports more than 300 papers focusing on LDP, but only 6% included more than 30 patients. Literature review confirms that LDP is a feasible and safe procedure in patients with benign or low grade malignancies. Decreased blood loss and morbidity, early recovery and shorter hospital stay may be the main advantages. Several concerns still exist for laparoscopic pancreatic adenocarcinoma excision. The individual surgeon determines the technical conduction of LDP, with or without spleen preservation; currently robotic pancreatic surgery has gained diffusion. Additional researches are necessary to determine the best technique to improve the procedure results.

Calcification of vestibular schwannoma: a case report and literature review  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Calcification rarely occurs in vestibular schwannoma (VS, and only seven cases of calcified VS have been reported in the literature. Here, we report a 48-year-old man with VS, who had a history of progressive left-sided hearing loss for 3 years. Neurological examination revealed that he had left-sided hearing loss and left cerebellar ataxia. Magnetic resonance imaging and computerized tomography angiography showed a mass with calcification in the left cerebellopontine angle (CPA. The tumor was successfully removed via suboccipital craniotomy, and postoperative histopathology showed that the tumor was a schwannoma. We reviewed seven cases of calcified VS that were previously reported in the literature, and we analyzed and summarized the characteristics of these tumors, including the calcification, texture, and blood supply. We conclude that calcification in VS is associated with its texture and blood supply, and these characteristics affect the surgical removal of the tumor.

Ethical community-engaged research: a literature review.  

Science.gov (United States)

Health research has relied on ethical principles, such as those of the Belmont Report, to protect the rights and well-being of research participants. Community-based participatory research (CBPR), however, must also consider the rights and well-being of communities. This requires additional ethical considerations that have been extensively discussed but not synthesized in the CBPR literature. We conducted a comprehensive thematic literature review and summarized empirically grounded discussions of ethics in CBPR, with a focus on the value of the Belmont principles in CBPR, additional essential components of ethical CBPR, the ethical challenges CBPR practitioners face, and strategies to ensure that CBPR meets ethical standards. Our study provides a foundation for developing a working definition and a conceptual model of ethical CBPR. PMID:24134352

Metronidazole Induced Pancreatitis. A Case Report and Review of Literature  

Directory of Open Access Journals (Sweden)

Full Text Available CONTEXT: Pancreatitis is a very rare adverse effect of metronidazole with only six cases of metronidazole-induced pancreatitis reported in the English literature so far. CASE REPORT: We report a case of recurrent acute pancreatitis in a 46-year-old female associated with oral metronidazole therapy and review the literature with regards to metronidazole-induced pancreatitis. We are also highlighting the fact that the time lag between metronidazole exposure and development of pancreatitis is very variable. CONCLUSION: High degree of suspicion is warranted on the part of physicians to diagnose metronidazole induced pancreatitis in patients presenting with gastrointestinal symptoms after metronidazole exposure. If metronidazole is suspected as the causative agent then it should be discontinued and rechallenge should be avoided.

Rebleeding After Aneurysmal Subarachnoid Hemorrhage : A Literature Review  

DEFF Research Database (Denmark)

OBJECTIVE: To summarize the current knowledge of the mechanisms leading to rebleeding and the prevention of rebleeding after subarachnoid hemorrhage (SAH). METHODS: A literature search was performed to investigate factors associated with rebleeding after SAH. RESULTS: The review of the literature revealed that rebleeding is a complex and multifactorial event involving hemostasis, pathophysiologic, and anatomic factors. Administration of antifibrinolytics has been shown to have a dramatic effect on the rebleeding rate, so changes in coagulation and fibrinolysis must be involved in rebleeding. CONCLUSIONS: Further studies are warranted before the exact mechanisms leading to rebleeding are established and the optimal preventive measures are made available. At the present time, antifibrinolytic therapy remains the only realistic protective measure during the initial 6 hours after SAH during which the rebleeding rate is highest.

Nontechnical Barriers to Solar Energy Use: Review of Recent Literature  

Energy Technology Data Exchange (ETDEWEB)

This paper reviews the nontechnical barriers to solar energy use, drawing on recent literature to help identify key barriers that must be addressed as part of the Technology Acceptance efforts under the U.S. Department of Energy (DOE) Solar America Initiative. A broad literature search yielded more than 400 references, which were narrowed to 19 recent documents on nontechnical barriers to the use of solar energy and other energy efficiency and renewable energy (EE/RE) technologies. Some of the most frequently identified barriers included lack of government policy supporting EE/RE, lack of information dissemination and consumer awareness about energy and EE/RE, high cost of solar and other EE/RE technologies compared with conventional energy, and inadequate financing options for EE/RE projects.

Effects of earthquakes on underground facilities. Literature review and discussion  

International Nuclear Information System (INIS)

A review of literature concerning effects of ground motion on underground facilities has been completed, and an annotated bibliography has been prepared. This information provides useful background for the science and engineering of underground nuclear waste management facility development. While some conflicts are evident in the literature reviewed, the following tentative conclusions may be drawn from the available information: (1) damage is expectable if fault displacement occurs through a site, but damage from shaking alone is generally confined to facilities located within the epicentral region and may be less than to surface facilities at the same site. (2) Seismic data are mixed, but favors reduction of amplitude with depth; observations appear quite dependent upon station characteristics. (3) The frequency content of earthquake mitions is important to the stability of underground openings and the applicability of attenuation relationships developed in areas where geologic and tectonic characteristics favor high attenuation rates to mid-continental sites is questionable. (4) Model studies indicate problems for shafts and the potential for problems with waste-handling equipment in shafts. The results of the review indicate the need to assure that site-specific response spectra and attenuation relationships are developed for proposed sites, and that detailed assessments of seismic aspects of shaft designs, hoists and in-shaft waste-handling equipment are required

The Health Effect of Psychostimulants: A Literature Review  

Directory of Open Access Journals (Sweden)

Full Text Available Prevalence of psychostimulant use is high, and raising in several countries. Nicotine is the legal stimulant causing the most important public health impact. Cocaine ranks among the most used illicit substances after cannabis. Stimulant medications are frequently misused. Psychostimulants can lead to addiction, have physical, psychological and social health consequences and can induce a great disease burden. The aim of the present article is to provide a literature review on the health effects of stimulants as potential drugs of abuse. It will cover essentially cocaine, amphetamines and its derivatives (including methamphetamines and 3-4-methylenedioxymethamphetamine, ecstasy, nicotine, caffeine and khat, and touch upon the issues of prescribed substances (anti-depressants, weight control medications, attention-deficit hyperactivity disorder medications, hypersomniac disorder. Their pharmacology, addictive potential, health consequences and treatment will be discussed. We used Medline for the literature review from 1990 to the date of this review, and mention the findings of human and animal studies (the latter only if they are of clinical relevance.

Tools that assess functional decline: systematic literature review update  

Directory of Open Access Journals (Sweden)

Full Text Available Kate Beaton, Karen Grimmer International Centre for Allied Health Evidence, University of South Australia, Adelaide, Australia Background: Screening for risk of functional decline in the elderly is increasingly important in ambulatory health care settings, to ensure that appropriate services are provided to reduce the risk of downstream decline. These screening tools should have sound psychometric properties and clinical utility. Design: An updated systematic literature review for (1 new screening tools published since the last review, conducted in 2007 and published in 2008, and (2 recent research into psychometric properties of the five tools identified in the previous review. Methods: A comprehensive review of multiple databases using the search terms from the Sutton et al review was conducted. The reference lists of included articles were hand-searched for additional articles, and the literature was evaluated with the appropriate critical appraisal tool. Included screening tools should be designed for, or applicable to, hospital emergency departments. Results: Two relevant new tools were identified (the Simplified PROFUNCTION index and Brief Risk Identification for Geriatric Health Tool. Six additional papers testing psychometric properties of four of the five previously reported screening tools were also found. Conclusion: Seven relevant screening tools are available with similar validity and reliability estimates. They consider similar constructs and have convincing evidence of applicability to a range of older populations, or different cultures. Identification of Seniors at Risk, is the most frequently reported screening tool. The wider unanswered question is how, why, and where these functional decline screening tools are used; how valid the findings are on ill, stressed, older people in emergency departments; and how the findings are acted upon in terms of community intervention to slow functional decline. Keywords: functional decline, older adults, screening and assessment tools

Electrophysiological examination in uveitis: a review of the literature  

Directory of Open Access Journals (Sweden)

Full Text Available Marilita M Moschos,1 Nikolaos S Gouliopoulos,1 Christos Kalogeropoulos2 1Laboratory of Electrophysiology, First Department of Ophthalmology, University of Athens, Athens, Greece; 2Department of Ophthalmology, University of Ioannina, Ioannina, Greece Purpose: Uveitis is the inflammation of the uveal tract, which usually also affects the retina and vitreous humor. The electrophysiological examination is an objective ocular examination that includes the electroretinogram, visual evoked potentials, the electrooculogram, the multifocal electroretinogram, and multifocal visual evoked potentials. Our aim is to review the literature of the use of the electrophysiological examination in cases of uveitis. Methods: We performed a systematic search of the literature of published papers until October 2012 using the PubMed search engine. The key terms that were used were “uveitis,” “electrophysiological examination”, “electroretinogram”, “visual evoked potentials”, “electro-oculogram”, “multifocal electroretinogram”, and “multifocal visual evoked potentials” in multiple combinations. To the best of our knowledge, this is the first review concerning the assessment of electrophysiology in uveitis. Results: Our search of the literature demonstrated that the electrophysiological examination, mainly by means of electroretinogram, multifocal electroretinogram, and visual evoked potentials, is performed in several cases of uveitis for many purposes, including diagnosis and monitoring of disease progression and treatment efficacy. The electrophysiological examination is more useful in patients with multiple evanescent white dot syndrome, acute posterior multifocal placoid pigment epitheliopathy, birdshot chorioretinopathy, Vogt–Koyanagi–Harada disease, Adamantiades–Behçet disease, ocular syphilis, and Fuchs heterochromic cyclitis. Conclusion: This review summarizes the use of the electrophysiological examination in uveitic patients and underlines its value as a useful tool in the objective assessment and the monitoring of the disease.

Home care in Europe: a systematic literature review  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Health and social services provided at home are becoming increasingly important. Hence, there is a need for information on home care in Europe. The objective of this literature review was to respond to this need by systematically describing what has been reported on home care in Europe in the scientific literature over the past decade. Methods A systematic literature search was performed for papers on home care published in English, using the following data bases: Cinahl, the Cochrane Library, Embase, Medline, PsycINFO, Sociological Abstracts, Social Services Abstracts, and Social Care Online. Studies were only included if they complied with the definition of home care, were published between January 1998 and October 2009, and dealt with at least one of the 31 specified countries. Clinical interventions, instrument developments, local projects and reviews were excluded. The data extracted included: the characteristics of the study and aspects of home care 'policy & regulation', 'financing', 'organisation & service delivery', and 'clients & informal carers'. Results Seventy-four out of 5,133 potentially relevant studies met the inclusion criteria, providing information on 18 countries. Many focused on the characteristics of home care recipients and on the organisation of home care. Geographical inequalities, market forces, quality and integration of services were also among the issues frequently discussed. Conclusions Home care systems appeared to differ both between and within countries. The papers included, however, provided only a limited picture of home care. Many studies only focused on one aspect of the home care system and international comparative studies were rare. Furthermore, little information emerged on home care financing and on home care in general in Eastern Europe. This review clearly shows the need for more scientific publications on home care, especially studies comparing countries. A comprehensive and more complete insight into the state of home care in Europe requires the gathering of information using a uniform framework and methodology.

A review of the literature on chiropractic and insomnia  

Science.gov (United States)

Objective The purpose of this literature review is to critically review the evidence for chiropractic as a treatment of primary insomnia. Methods A search of the following databases up to October 2006 was conducted: PubMed, PEDro, MANTIS, CINAHL, and the specialized register of the Cochrane review group. We also performed hand searching of relevant journals. Randomized clinical trials, clinical trials, and case studies of chiropractic treatment of insomnia were included. It was required that each study used at least one form of standard patient outcome measure. Treatment strategies included manual therapy such as spinal manipulative therapy or muscle relaxation techniques. The review focused on articles published in indexed, peer-reviewed journals. Results Fifteen studies met the selection criteria. There were no randomized clinical trials specific to chiropractic and insomnia. One study was a survey of opinion for treatment regimens for insomnia, which had low methodological scores. Another study assessed osteopathic cranial manipulation for insomnia, which appeared to have positive effects. Four studies identified physiotherapy treatment and manual therapy. A further 9 studies related to mind-body medical therapies and impaired health status, sleep disorders, and pain in the craniomandibular and cervical spinal regions. Conclusion Some studies have noted improvement in insomnia following manual therapy; however, based on clinical trials, there is minimal evidence of support for chiropractic in insomnia. Further studies with high methodological scores need to be conducted. PMID:22027034

Spontaneous coronary artery dissections: Four cases and literature review  

Directory of Open Access Journals (Sweden)

Full Text Available Spontaneous coronary artery dissection(SCAD is a very rare cause of acute coronary syndrome. SCAD can cause stable angina, unstable angina, acute myocardial infarction, cardiogenic shock and sudden cardiac death. Predisposing factors include atherosclerosis, the peripar-tum period, structural and inflammatory conditions affect-ing the arterial wall. The diagnosis is usually made by coronary angiography. The clinical presentation is similar to the atherosclerotic coronary artery disease. Prompt diagnosis and treatment of patients improves survival. Therapeutic options include medical therapy, percutane-ous coronary intervention and surgery. The four cases were presented an discussed with review of the pertinent literature.

Amyloid goiter: two cases and a review of the Literature  

International Nuclear Information System (INIS)

Although involvement of the thyroid gland by amyloid is a relatively common phenomenon, clinically significant enlargement of the thyroid owing to amyloid deposition is an extremely rare occurrence. We describe two cases of amyloid goiter and review the relevant literature. The first case was systemic amylloidosis secondary to familial Mediterranean fever. The second case was a chronic renal failure patient who presented with an enlarged thyroid and upper airway obstructive symptoms. To date, true amyloid goiter secondary to amyloidosis associated with familial Mediterranean fever has only been reported in twelve patients. (author)

Bouveret's Syndrome: Case Report and Review of the Literature  

Directory of Open Access Journals (Sweden)

Full Text Available Bouveret's syndrome is defined as gastric outlet obstruction caused by duodenal impaction of a large gallstone which passes into the duodenal bulb through a cholecystogastric or cholecystoduodenal fistula. Initial attempts at endoscopic retrieval with or without mechanical or extracorporeal lithotripsy should be performed as first-line treatment, though success rates with endoscopic treatment are variable. We describe a case of Bouveret's Syndrome in an elderly patient that was successfully treated with endoscopic extraction combined with mechanical lithotripsy, and review the literature on this uncommon condition.

Achromobacter species endocarditis: A case report and literature review.  

Science.gov (United States)

Endocarditis due to Achromobacter species is a rare, yet serious, endovascular infection. Achromobacter species infective endocarditis is associated with underlying immunodeficiencies or prosthetic heart valves and devices. A case of prosthetic pulmonary valve endocarditis secondary to Achromobacter xylosoxidans subspecies denitrificans is described in the present report. This life-threatening infection was successfully treated with combined valve replacement and prolonged antibiotic therapy. A Medline/PubMed literature review of Achromobacter endocarditis was also performed. Achromobacter species are an uncommon, yet important, cause of nosocomial endocarditis. Given the significant associated morbidity and mortality, along with a high degree of intrinsic antibiotic resistance, Achromobacter species infective endocarditis remains a clinical treatment challenge.

Computerized tomography and schizophrenia: critical review of the literature  

International Nuclear Information System (INIS)

A critical review of the literature regarding structural brain abnormalities in Schizophrenia is presented. It is reported that the prevalence and the localization of the abnormalities vary widely among studies. These differences might stem from samples heterogeneity, from the choice of the computer tomographic (CT) parameter to be investigated and from the use of different criteria for defining abnormalities. It seems established that at least one subgroup of Schizophrenia patients shows mild or moderate brain atrophy, in spite of some contradictory findings. (M.A.C.)

Nutrition and air-fluidized beds: a literature review.  

Science.gov (United States)

This is a review of the literature on air-fluidized beds and nutrition with an emphasis on patients with pressure ulcers. Studies suggest that the warm, dry environment of the air-fluidized bed may affect nutritional status. Patients maintained on air-fluidized beds have increased fluid losses and decreased urinary nitrogen losses. While the evidence suggests that air-fluidized beds may reduce protein catabolism, further and lengthier metabolic studies are needed. Clinicians should continue to provide high levels of energy and protein for patients with pressure ulcers on air-fluidized beds. PMID:7827739

Threatening faces and social anxiety: A literature review  

DEFF Research Database (Denmark)

A threatening facial expression is a potent social sign of hostility or dominance. During the past 20 years, photographs of threatening faces have been increasingly included as stimuli in studies with socially anxious participants, based on the hypothesis that a threatening face is especially salient to people with fears of social interaction or negative evaluation. The purpose of this literature review is to systematically evaluate the accumulated research and suggest possible avenues for further research. The main conclusion is that photographs of threatening faces engage a broad range of perceptual processes in socially anxious participants, particularly when exposure times are very short

Evaluation of hydroxamic acid in uranium extraction process : literature review  

International Nuclear Information System (INIS)

The Uranium Extraction (UREX) process is being developed for the spent oxide fuel from light water reactors as part of the Accelerator Transmutation of Waste Project. The UREX process is similar to the Plutonium and Uranium Extraction (PUREX) process in that it involves solvent extraction based on a tributyl phosphate extractant. To assure that actinide reduction and complexation are effective, the reductant/complexant aceto-hydroxamic acid is being considered for use in the UREX process. The following literature review describes the solvent extraction, kinetics, oxidation-reduction, and complexation properties of aceto-hydroxamic acid and its derivatives

Brief literature review pertinent to steam generator water hammer  

International Nuclear Information System (INIS)

Analysis of water hammer in steam generators requires the following information: dynamic equations on the steam supply side and on the water side which are sufficiently simple for practical solution, and yet which are descriptive of the main features of the steam and water flows affecting the behavior of the steam/cold water interface; and fairly reliable estimates of the heat transfer coefficients under highly transient conditions of steam cold water interfaces. This review deals mainly with literature measurements relative to item 2, but will also discuss dynamic modeling in connection with the chugging problem in BWR pressure suppression pools, which has many points of similarity with water hammer in steam generators

Full Text Available Lucylynn Lizarondo1, Saravana Kumar1, Lisa Hyde2, Dawn Skidmore21International Centre for Allied Health Evidence, School of Health Sciences, University of South Australia, Adelaide; 2South Australian Health Allied and Scientific Health Office, Adelaide, AustraliaObjective: Allied health assistants (AHAs are an emerging group in allied health practice with the potential to improve quality of care and safety of patients. This systematic review summarizes the evidence regarding the roles and responsibilities of AHAs and describes the benefits and barriers to utilizing AHAs in current health care settings.Methods: A systematic process of literature searching was undertaken. A search strategy which included a range of electronic databases was searched using key terms. Studies which examined the roles and responsibilities of AHAs (across all allied health disciplines were included in the review. Only publications written in the English language were considered, with no restriction on publication date. Two reviewers independently assessed eligibility of the articles. Data extraction was performed by the same reviewers. A narrative summary of findings was presented.Results: Of the initial 415 papers, 10 studies were included in the review. The majority of papers reported roles performed by general health care assistants or rehabilitation assistants who work in multiple settings or are not specifically affiliated to a health discipline. All ­current AHAs duties have elements of direct patient care and indirect support via clerical and ­administrative or housekeeping tasks. Benefits from the introduction of the AHA role in health care include improved clinical outcomes, increased patient satisfaction, higher-level services, and more “free” time for allied health professionals to concentrate on patients with complex needs. ­Barriers to the use of AHAs are related to blurred role boundaries, which raises issues associated with professional status and security.Conclusions: There is consensus in the literature that AHAs make a valuable contribution to allied health care. Whilst there are clear advantages associated with the use of AHAs to support allied health service delivery, ongoing barriers to their effective use persist.Keywords: allied health assistants, health care assistants, rehabilitation assistants, allied health workforce

Síndrome de fragilidade no idoso: uma revisão narrativa / The frailty syndrome in elderly: a narrative review  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: Portuguese Abstract in portuguese Este estudo se propôs a realizar uma revisão narrativa sobre a temática da síndrome da fragilidade no idoso, visto que a literatura ainda carece de unanimidade quanto a sua conceituação. A revisão foi realizada nos meses de maio e junho de 2012, por meio dos descritores frailty, aged, frail elderly [...] e aging e seus respectivos correspondentes em português nas bases de dados LILACS, MEDLINE, SciELO e PubMed. A amostra contemplou artigos publicados de 1990 a 2012, resultantes de pesquisas primárias quantitativas, qualitativas e estudos teóricos. Os 58 artigos selecionados na amostra final apontaram diferentes instrumentos metodológicos para identificar e quantificar a presença de fragilidade nos idosos. Demonstraram que a fragilidade no idoso envolve múltiplas dimensões e pode ser influenciada por fatores ligados ao próprio indivíduo ou fatores externos, os quais resultam em diferentes conceitos da síndrome da fragilidade no idoso. Conclui-se que os pesquisadores da área estão investindo na geração de conhecimento com o intuito de elaborar uma única definição que possa contemplar com mais propriedade o conceito da síndrome de fragilidade no idoso, contribuindo na mudança de desfechos adversos, podendo intervir na prevenção e promoção de saúde nesses idosos. Abstract in english This study aimed to conduct a literature review on the topic of the frailty syndrome in the elderly, since the literature still lacks unanimity on its conceptualization. One review was held in May and June 2012, through the descriptors frailty, aged, frail elderly and aging and their counterparts in [...] Portuguese in LILACS, MEDLINE, PubMed and SciELO databases. The sample included articles published from 1990 to 2012, resulting from quantitative, qualitative primary research and theoretical studies. The 58 articles selected in the final sample showed different methodological tools to identify and quantify the presence of frailty in the elderly. They showed that frailty in elderly involves multiple dimensions and can be influenced by factors related to the individual himself or external factors, which result in different concepts of the frailty syndrome in the elderly. We conclude that researchers in the field are investing in the generation of knowledge in order to develop a single definition that can include more properly the concept of frailty syndrome in the elderly, helping change adverse outcomes, and intervening in the prevention and promotion health to them.

Qualitative Research on Emergency Medicine Physicians : A literature review  

DEFF Research Database (Denmark)

Aim: This study aims to systematically review the qualitative research studying Emergency Medicine (EM) physicians in Emergency Departments (ED). Background: Qualitative research aims to study complex social phenomena. EM is a highly complex medical and social environment that can be investigated with qualitative research. Methods: Electronic databases of English peer-reviewed articles were searched from 1971 to 2012 using Medline through PubMed and PsychINFO. This search was supplemented with hand-searches of Academic Emergency Medicine and Emergency Medicine Journal from 1999 to 2012 and cross references were reviewed. The key words used were emergency medicine, qualitative, ethnography, observation, interview, video, anthropology, simulation, and simulation-based. Results: 820 papers were identified and 46 studies were included in this review. This literature review found that the reviewed qualitative studies on EM physicians were designed using the following strategies of inquiry: Ethnography, mixed methods, action research, grounded theory, phenomenology, content analysis, discourse analysis, and critical incident analysis. The reviewed studies were categorized into four main themes: Education and training, communication, professional roles, and organizational factors, and into 12 sub-themes. Conclusion: The strength of qualitative research is its ability to grasp and operationalize complex relations within EM. Although qualitative research methodologies have gained in rigour in recent years and few researchers would question their value in studying complex social phenomena and settings such as EM and ED, more rigorous design in qualitative studies are needed. A stricter adherence to one strategy of inquiry would yield more valid studies in qualitative terms concerning validity, reliability and transferability.

Condylar positioning devices for orthognathic surgery: a literature review.  

Science.gov (United States)

In the past few years, many devices have been proposed for preserving the preoperative position of the mandibular condyle during bilateral sagittal split osteotomy. Accurate mandibular condyle repositioning is considered important to obtain a stable skeletal and occlusal result, and to prevent the onset of temporomandibular disorders (TMD). Condylar positioning devices (CPDs) have led to longer operating times, the need to keep intermaxillary fixation as stable as possible during their application, and the need for precision in the construction of the splint or intraoperative wax bite. This study reviews the literature concerning the use of CPDs in orthognathic surgery since 1990 and their application to prevent skeletal instability and contain TMD since 1995. From the studies reviewed, we can conclude that there is no scientific evidence to support the routine use of CPDs in orthognathic surgery. PMID:18417381

Modern and contemporary physics teaching: a review on recent literature  

Directory of Open Access Journals (Sweden)

Full Text Available This paper presents a review of the literature on the teaching of modern and contemporary physics performed by consulting the articles published in leading Brazilian and international journals of science education in the period 2001 to 2006. The research focused on the papers targeted to education and it resulted in a sample of 102 articles. The studies reviewed were classified into four broad categories: didactical proposals tested in classroom, bibliographical reference to teachers, survey of misconceptions, curriculum analysis. It is possible to note that, despite a significant increase on publications on the teaching of modern and contemporary physics presenting research results, most articles still refer to bibliographical reference for teachers. Although there are a considerable number of studies involving new teaching proposals, there are few studies that investigate the mechanisms involved in the process of building knowledge related to topics of modern and contemporary physics in the classroom.

Issues in benchmarking human reliability analysis methods : a literature review.  

Energy Technology Data Exchange (ETDEWEB)

There is a diversity of human reliability analysis (HRA) methods available for use in assessing human performance within probabilistic risk assessment (PRA). Due to the significant differences in the methods, including the scope, approach, and underlying models, there is a need for an empirical comparison investigating the validity and reliability of the methods. To accomplish this empirical comparison, a benchmarking study is currently underway that compares HRA methods with each other and against operator performance in simulator studies. In order to account for as many effects as possible in the construction of this benchmarking study, a literature review was conducted, reviewing past benchmarking studies in the areas of psychology and risk assessment. A number of lessons learned through these studies are presented in order to aid in the design of future HRA benchmarking endeavors.

Product-related Environmental Performance Indicators: a systematic literature review  

DEFF Research Database (Denmark)

Ecodesign is a proactive environmental management approach employed in the product development process (PDP) which aims to minimize the environmental impacts caused during products’ life-cycle, improving its environmental performance. The establishment of measurable environmental performance indicators (EPIs) during PDP is often cited as a successful factor for effective ecodesign implementation, since it enables the monitoring towards the accomplishment of environmental performance improvement goals. However, companies still face difficulties in the selection and application of EPIs - a more structured approach to support EPIs selection is still lacking. This paper presents the efforts made in order to identify, classify and systematize the existing EPIs based on the systematic literature review. From the review, 261 EPIs were identified, classified, and then systematized in a digital database. The results and the state of art regarding environmental performance indicators are presented in this paper.

Iodine intake in human nutrition: a systematic literature review  

Directory of Open Access Journals (Sweden)

Full Text Available The present literature review is a part of the NNR5 project with the aim of reviewing and updating the scientific basis of the 4th edition of the Nordic Nutrition Recommendations (NNR issued in 2004. The main objective of the review is to assess the influence of different intakes of iodine at different life stages (infants, children, adolescents, adults, elderly, and during pregnancy and lactation in order to estimate the requirement for adequate growth, development, and maintenance of health. The literature search resulted in 1,504 abstracts. Out of those, 168 papers were identified as potentially relevant. Full paper selection resulted in 40 papers that were quality assessed (A, B, or C. The grade of evidence was classified as convincing, probable, suggestive, and no conclusion. We found suggestive evidence for improved maternal iodine status and thyroid function by iodine supplementation during pregnancy. Suggestive evidence was found for the relationship between improved thyroid function (used as an indicator of iodine status during pregnancy and cognitive function in the offspring up to 18 months of age. Moderately to severely iodine-deficient children will probably benefit from iodine supplementation or improved iodine status in order to improve their cognitive function, while only one study showed improved cognitive function following iodine supplementation in children from a mildly iodine-deficient area (no conclusion. No conclusions can be drawn related to other outcomes included in our review. There are no new data supporting changes in dietary reference values for children or adults. The rationale for increasing the dietary reference values for pregnant and lactating women in the NNR5 needs to be discussed in a broader perspective, taking iodine status of pregnant women in the Nordic countries into account.

Full Text Available Objectives: The restoration of edentulous posterior maxilla with dental implants is challenging due to a deficient posterior alveolar ridge. Over the last decade an advance in the graftless bone augmentation procedures had occurred where the space left beneath the Schneiderian membrane is filled with blood clot in order to produce bone formation. The aim of present article is to review the scientific literature with respect to bone formation in the sinus, after membrane elevation procedure, without using any bone substitutes. Material and Methods: A comprehensive review of the current literature was conducted according to the PRISMA guidelines by accessing the NCBI PubMed database. The articles were searched from 1993 to 2013. English language articles with minimum one year patient follow-up and radiological and/or histological diagnostics of newly formed bone were included. Articles were excluded, if usage of bone graft or bone substitutes and/or usage of osteotome has been made during sinus lift operation. Results: A total of 19 studies were included: 2 studies were related to the sinus membrane’s osteogenic potential, 3 to the histological evidence of bone formation in monkeys and humans, 12 to the radiologic evidence of bone gain, and 2 to the space-maintaining management. 100% of the reviewed articles presented with increased bone formation and high implant survival rates resulting from the graft-free technique. Conclusions: It is clearly shown in the review that the potential of the maxillary sinus to heal and to form new bone without bone grafts or substitutes is of high nature.

SKU classification: A literature review and conceptual framework  

DEFF Research Database (Denmark)

Purpose: Stock Keeping Unit (SKU) classifications are widely used in the field of production and operations management. Although many theoretical and practical examples of classifications exist, there are no overviews of the current literature, and general guidelines are lacking with respect to method selection for classifying SKUs. The purpose of this paper is to systematically synthesise the earlier work in this area, and to conceptualise and discuss the factors that influence the choice of a specific SKU classification. Design/methodology/approach: This paper structurally reviews existing contributions and synthesises these into a conceptual framework for SKU classification. Findings: How SKUs are classified depends on the classification aim, the context and the method that is chosen. Three main production and operations management aims where found: inventory management, forecasting and production strategy. Within the method three decisions are identified to come to a classification: the characteristics, the classification technique and the operationalisation of the classes. Research limitations/implications: Drawing on our literature survey, we conclude with a conceptual framework describing the factors that influence SKU classification. Further research could use this framework to develop guidelines for real-life applications. Practical implications: Examples from a variety of industries and general directions are provided thatwhich managers could use to develop their own SKU classification. Originality/value: This paper aims to advance the literature on SKU classification from the level of individual examples to a conceptual level and provides directions on how to develop a SKU classification.

Management of pain in the newborn: literature review  

Directory of Open Access Journals (Sweden)

Full Text Available Objective: to outline the evolution of concepts of pain in the newborn and measures for its control. Methodology: this is a descriptive literature study from the literature review type. The articles used were published in the last decade, from 1998 to 2008. Data collection took place between August and September 2008. To search the Virtual Health Library (VHL and other sources were used descriptors: nursing, pain and newborn. Were considered thirty-five publications they are referred to the aim of this study. The texts were read, analyzed, organized and classified according to the following categories: concept and management of pain in infants. Results: the pain is discussed since the dawn of humanity and studied by several civilizations. At first it was believed that the newborn did not feel pain, today not only does the pain of the RN as something scientifically proven, but it also proposes measures for its control. These measures are pharmacological and nonpharmacological. Conclusion: Despite technological advances and studies, perceived that it is scarce literature on the subject and also there are few studies related to pain in neonatal nursing. Further studies are needed to further investigations and improvement of care in neonatology.

Mindfulness-based interventions for physical conditions: a narrative review evaluating levels of evidence.  

Science.gov (United States)

Research on mindfulness-based interventions (MBIs) for treating symptoms of a wide range of medical conditions has proliferated in recent decades. Mindfulness is the cultivation of nonjudgmental awareness in the present moment. It is both a practice and a way of being in the world. Mindfulness is purposefully cultivated in a range of structured interventions, the most popular of which is mindfulness-based stress reduction (MBSR), followed by mindfulness-based cognitive therapy (MBCT). This paper begins with a discussion of the phenomenological experience of coping with a chronic and potentially life-threatening illness, followed by a theoretical discussion of the application of mindfulness in these situations. The literature evaluating MBIs within medical conditions is then comprehensively reviewed, applying a levels of evidence rating framework within each major condition. The bulk of the research looked at diagnoses of cancer, pain conditions (chronic pain, low back pain, fibromyalgia, and rheumatoid arthritis), cardiovascular disease, diabetes, human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS), and irritable bowel syndrome. Most outcomes assessed are psychological in nature and show substantial benefit, although some physical and disease-related parameters have also been evaluated. The field would benefit from more adequately powered randomized controlled trials utilizing active comparison groups and assessing the moderating role of patient characteristics and program "dose" in determining outcomes.

THE ‘SOCIAL MODEL OF DISABILITY’ MET A NARRATIVE OF (INCREDULITY: A REVIEW  

Directory of Open Access Journals (Sweden)

Full Text Available The article reviews components and recent discussion of the ‘Social Model of Disability’, with special focus on two books, Disability Rights and Wrongs by Tom Shakespeare, and The Social Model: Europe and the Majority World edited by Colin Barnes and Geof Mercer. The ‘Social Model’ calls for close and sceptical scrutiny, as it has become one of the most influential metanarratives in campaigns and publications of the ‘Disability Movement’, while tending to overlook the complexities experienced by many disabled people and their relatives. Some components of a Social Model appear in historical literature of Asia and the Middle East, lending credibility to its ongoing life as an interesting idea. Yet current anglophone advocacy of the model makes assumptions of universality that are questionable in the socio-economic situations experienced by much of the global population having disabilities. A calmer and better informed discussion of the model’s merits and flaws would contribute to greater understanding of global disability.DOI 10.5463/DCID.v22i1.14

Milk, dairy products, and their functional effects in humans: a narrative review of recent evidence.  

Science.gov (United States)

Milk is a widely consumed beverage that is essential to the diet of several millions of people worldwide because it provides important macro- and micronutrients. Milk is recognized as being useful during childhood and adolescence because of its composition; however, its relatively high saturated fat proportion raises issues of potential detrimental effects, namely on the cardiovascular system. This review evaluates the most recent literature on dairy and human health, framed within epidemiologic, experimental, and biochemical evidence. As an example, the effects of milk (notably skimmed milk) on body weight appear to be well documented, and the conclusions of the vast majority of published studies indicate that dairy consumption does not increase cardiovascular risk or the incidence of some cancers. Even though the available evidence is not conclusive, some studies suggest that milk and its derivatives might actually be beneficial to some population segments. Although future studies will help elucidate the role of milk and dairy products in human health, their use within a balanced diet should be considered in the absence of clear contraindications.

Asthma and cigarette smoking: a review of the empirical literature.  

Science.gov (United States)

The purpose of this review paper is to present and evaluate the empirical literature on the association between asthma and cigarette smoking. The authors conducted a literature search utilizing electronic search engines (i.e., PsycINFO and MEDLINE) to examine databases using the following key word algorithms: smoking OR nicotine OR tobacco AND asthma. Only articles that focused on active tobacco smoking and analyzed groups with asthma patients only were examined in the present review. Overall, empirical evidence suggests that (1) smoking is more prevalent among individuals with asthma than those without; (2) smoking is a risk candidate for the development of asthma; (3) smoking is associated with decreased asthma control and increased risk of mortality and asthma attacks and exacerbations; (4) smokers with and without asthma may have different risk factors for smoking onset as well as different smoking motives and outcome expectancies; and (5) smoking cessation is associated with improvements in lung functioning and asthma symptoms. Future work in this domain of study will lead to clinically relevant health care advances as well as the development of theoretically driven, methodologically diverse lines of research exploring asthma-smoking comorbidity issues.

Spiritually and religiously integrated group psychotherapy : a systematic literature review  

DEFF Research Database (Denmark)

WE SYSTEMATICALLY REVIEWED THE RESEARCH LITERATURE ON SPIRITUALLY AND RELIGIOUSLY INTEGRATED GROUP PSYCHOTHERAPY TO ANSWER THE FOLLOWING THREE QUESTIONS: first, how are spirituality and religiosity defined; second, how are spiritual and religious factors characterized and integrated into group psychotherapy; and, third, what is the outcome of the group psychotherapies? We searched in two databases: PsycINFO and PubMed. Inclusion and exclusion criteria and checklists from standardized assessment tools were applied to the research literature. Qualitative and quantitative papers were included. In total, 8 articles were considered eligible for the review. Findings from the evaluation suggested that the concepts of spirituality and religiosity were poorly conceptualized and the way in which spiritual and religious factors were integrated into such group psychotherapies, which distinguished it from other types of group psychotherapies, was not fully conceptualized or understood either. However, clear and delimited conceptualization of spiritual and religious factors is crucial in order to be able to conclude the direct influences of spiritual or religious factors on outcomes. Implications for spiritually or religiously integrated group psychotherapy and conducting research in this field are propounded.

Factor XIII deficiency management: a review of the literature.  

Science.gov (United States)

Factor XIII (FXIII) deficiency is a rare congenital bleeding disorder estimated to affect 1 in 2 million live births. Treatment often involves prophylaxis with FXIII concentrate and is especially important in preventing intracranial hemorrhage (ICH) and maintaining pregnancy in women of childbearing age. The rarity of this condition and lack of good quality evidence has resulted in a literature largely based on case reports/case series. A review of the literature was conducted in order to provide information about the optimal management of FXIII deficiency. Articles were identified by searching MEDLINE from 1961 to June 2012. Eligible studies included details on patients with FXIII deficiency that received treatment. Information collected included dose, frequency, duration, hemostatic efficacy and adverse events. Of 606 abstracts reviewed, 43 articles, including a total of 328 patients met the selection criteria. Common bleeding manifestations included umbilical cord bleeding, ICH and hematomas. Patients were generally placed on prophylactic factor replacement therapy upon diagnosis of severe or symptomatic FXIII deficiency, which decreased and/or prevented bleeding episodes. Patients with FXIII deficiency that received prophylactic treatment successfully maintained pregnancies. Alternative treatments included the use of cryoprecipitate or frozen plasma when FXIII concentrate was not available or affordable. Recent studies of a new recombinant FXIII concentrate show promising results in regards to safety and efficacy. There are limited data to guide the optimal treatment of FXIII deficiency. Larger patient registries and international collaborations are needed to improve the evidence and enhance clinical outcomes in this rare bleeding disorder. PMID:24401950

Complications associated with arthroscopic rotator cuff repair: a literature review.  

Science.gov (United States)

The aim of this literature review was to report complications associated with arthroscopic rotator cuff repair (RCR). A computerized search of articles published between 200 and 2009 was performed using MEDLINE and PubMed. We included clinical studies (Level 1-4): (a) investigating patients with rotator cuff tears, managed by a completely arthroscopic RCR technique; (b) reported data about complications. Data about arthroscopic-assisted techniques were excluded. Articles that meet criteria inclusion were analytically examined. Complications were classified into general complications and specific complications related to arthroscopic RCR. We found 414 complications in 2,890 patients; most of them were specific complications related to arthroscopic RCR. Re-rupture was the most frequently encountered complication: re-tear rate ranged between 11.4 and 94%. Stiffness and hardware-related complications were observed in 74 and 12 patients, respectively. Eleven less common complications were also reported: 5 neurovascular, 3 septic, 2 thromboembolic events, and 1 anesthesiological complication. This review stated that arthroscopic RCR is a low-risk surgical procedure. Anatomical failure of the repair is the most common complication encountered in the literature. PMID:22205384

Cervical Disc Replacement: A Systematic Review of Medline Indexed Literature  

Directory of Open Access Journals (Sweden)

Full Text Available Anterior Cervical Discectomy and Fusion (ACDF currently remains as the gold standard treatment for cervical disc herniation and Degenerative Disc Disease (DDD refractory to conservative management. Even though anterior cervical fusion provides excellent clinical results, it has been implicated in abnormal kinematic strain on adjacent disc level resulting in symptomatic adjacent segment disease. Anterior cervical disc replacement (ACDR is an alternative procedure to anterior cervical discectomy and fusion. The aims of cervical disc replacement were to preserve the motion at the index level and to protect the adjacent levels from accelerated symptomatic degeneration. The aim of this systematic review was to evaluate the outcomes of cervical disc replacement published in MEDLINE indexed literature. A literature search was carried out in medical electronic database MEDLINE. Keywords used for the search were Cervical vertebrae, Cervical spine, Neck, Intervertebral disc, Total disc replacement, Arthroplasty, Replacement, Treatment outcome. Two authors reviewed titles and abstracts of all two hundred and thirty six hits. The articles that satisfied the inclusion criteria were critically appraised while remaining articles were discarded. Anterior cervical disc replacement is a relatively new technology in spinal surgery. There are several short and intermediate term follow-up studies to prove the safety and efficacy of ACDR with satisfactory clinical and radiological outcomes. More intermediate to long-term follow-up studies are needed to prove the safety and efficacy of ACDR.

Moving health promotion communities online: a review of the literature.  

Science.gov (United States)

There is a need to enhance the effectiveness and reach of complex health promotion initiatives by providing opportunities for diverse health promotion practitioners and others to interact in online settings. This paper reviews the existing literature on how to take health promotion communities and networks into online settings. A scoping review of relevant bodies of literature and empirical evidence was undertaken to provide an interpretive synthesis of existing knowledge on the topic. Sixteen studies were identified between 1986 and 2007. Relatively little research has been conducted on the process of taking existing offline communities and networks into online settings. However, more research has focused on offline (i.e. not mediated via computer networks); 'virtual' (purely online with no offline interpersonal contact); and 'multiplex' communities (i.e. those that interact across both online and offline settings). Results are summarised under three themes: characteristics of communities in online and offline settings; issues in moving offline communities online, and designing online communities to match community needs. Existing health promotion initiatives can benefit from online platforms that promote community building and knowledge sharing. Online e-health promotion settings and communities can successfully integrate with existing offline settings and communities to form 'multiplex' communities (i.e. communities that operate fluently across both online and offline settings).

Human factors evaluation of teletherapy: Literature review. Volume 5  

Energy Technology Data Exchange (ETDEWEB)

A series of human factors evaluations were undertaken to better understand the contributing factors to human error in the teletherapy environment. Teletherapy is a multidisciplinary methodology for treating cancerous tissue through selective exposure to an external beam of ionizing radiation. A team of human factors specialists, assisted by a panel of radiation oncologists, medical physicists, and radiation therapists, conducted site visits to radiation oncology departments at community hospitals, university centers, and free-standing clinics. A function and task analysis was performed initially to guide subsequent evaluations in the areas of workplace environment, system-user interfaces, procedures, training, and organizational practices. To further acquire an in-depth and up-to-date understanding of the practice of teletherapy in support of these evaluations, a systematic literature review was conducted. Factors that have a potential impact on the accuracy of treatment delivery were of primary concern. The present volume is the literature review. The volume starts with an overview of the multiphased nature of teletherapy, and then examines the requirement for precision, the increasing role of quality assurance, current conceptualizations of human error, and the role of system factors such as the workplace environment, user-system interfaces, procedures, training, and organizational practices.

Basin resource management for carbon storage. A literature review  

Energy Technology Data Exchange (ETDEWEB)

Supported by ANLEC R and D, CSIRO and Curtin University are jointly conducting an assessment of the site specific resources that are geographically co-located with proposed carbon storage. The project also aims to understand the structural, stratigraphic and geomechanical aspects at proposed storage sites in the Southern Perth Basin, the Gippsland Basin, and the Surat Basin, in Australia to assess the potential impacts of CO{sub 2} injection on adjacent resources. This literature review and data gap analysis forms a first step of the study to understanding the present level of knowledge for conducting such an assessment. The literature reviewed relates both to any direct assessment of potential impacts of CO{sub 2} on other natural resources, as well as those that contain valuable information that would be used for making such an assessment. These include reports on hydrogeology and groundwater prospectivity, hydrocarbon and coal occurrence, geomechanical and structural assessment, and other relevant site specific studies on carbon dioxide storage.

Organizational Commitment, job satisfaction and intention to stay: Literature review  

Directory of Open Access Journals (Sweden)

Full Text Available Purpose: The aim of this paper is to analyse the existing theoretical frameworks of organisational behaviour and job satisfaction while taking into account, in connection with working conditions, the social and economic changes that are taking place in most of the western countries. The analysis and discussion suggest the need for new lines of research to determine whether the current practices carried out in human resources departments are well directed. Design/methodology/approach: First, we show a short review of the classical literature and the predominant paradigms through an exhaustive review of the scientific literature that has led to their subsequent evolution. Afterwards, we analyse the evidence sustaining their evolution in the light of the current changes, and we explain the future research needs from a theoretical point of view. Research limitation/implications: Owing to the nature of the article, it is a theoretical essay to launch a new scientific debate in connection with the models displayed and fully justified. Practical implications depend on the development of future research, as justified at all times. Originality/value: Currently, few investigations and theoretical contributions have taken into account the increase in contingent work, and more specifically moonlighting, either from an empirical perspective or as a theoretical critique of the existing organisational behaviour models. The main value of this essay is its invitation to take control of the debate while analysing its possible practical implications.

Sickle Cell Disease Pain Management in Adolescents: A Literature Review.  

Science.gov (United States)

Sickle cell disease (SCD) pain continues to emerge in adolescents. More than 98,000 individuals are believed to have SCD in the United States. In fact, 1 in 500 Black infants will be affected by SCD. Identifying standards of care for this unique population can improve pain management and treatment. A significant effect of vaso-occlusive crisis is a decrease in the quality of life in children. Therefore, pain management is multidimensional and includes pharmacologic, physical, and psychological strategies. A review of the literature was conducted to identify best practices regarding pain management in adolescents with sickle cell anemia. Key words such as pain, pain management, adolescent sickle cell anemia, and acute sickle cell pain were entered into databases to reveal qualitative and quantitative studies from 2009 to the present. Many of the research articles identified poor SCD pain management. Studies showed that acute SCD pain management is essential and should be evaluated and robustly managed to achieve optimum pain relief for patients. Acute SCD pain usually occurs as a result of vaso-occlusive crisis. Untreated acute SCD pain can result in morbidity and mortality in adolescents. Nursing knowledge is critical to reducing the stigma and improving management of SCD pain. Nurses play a vital role in the introduction of evidence-based practice within the clinical setting. In an effort to educate nurses and other health care professionals about SCD, this article is a literature review of studies concerning SCD and pain management in emergency rooms. PMID:25175555

Capsular block syndrome: a case report and literature review  

Science.gov (United States)

Purpose To report the case of a patient who developed late capsular block syndrome and to review the current literature regarding this complication of phacoemulsification procedures. Methods The literature was reviewed to summarize the diagnosis, classification, use of diagnostic aids, and the current treatments for this complication. Results A 69-year-old patient complained of decreased visual acuity 11 months after undergoing phacoemulsification. She was found to have a secondary myopization. Anterior segment ultrabiomicroscopy confirmed the diagnosis of capsular block syndrome. The patient underwent neodymium-doped yttrium aluminum garnet (Nd:YAG) laser posterior capsulotomy, which resulted in complete resolution of her symptoms. Conclusion Capsular block syndrome is a fairly rare complication of phacoemulsification procedures that, depending primarily on the timing of its occurrence following surgery, can develop into one of the three following possible clinical scenarios: intraoperatory, early postoperatory, and late postoperatory. In this patient, Nd:YAG laser capsulotomy was shown to be a safe and effective treatment option for this type of complication. PMID:25152612

Defining Anxious Depression: A Review of the Literature  

Science.gov (United States)

The diagnosis of anxious depression is presently inconsistent. The many different definitions of anxious depression have complicated its diagnosis, leading to clinical confusion and inconsistencies in the literature. This paper reviewed the extant literature in order to identify the varying definitions of anxious depression, which were then compared using Feighner’s diagnostic criteria. Notably, these suggest a different clinical picture of patients with anxious depression. For instance, relying on ICD-10 or DSM diagnoses yields a clinical picture of a comparatively mild or transient disorder; in contrast, using dimensional criteria such as DSM criteria combined with additional rating scales—most commonly the anxiety somatization factor score from the Hamilton Depression Rating Scale (HAM-D)—yields a more serious clinical picture. The evidence reviewed here suggests that defining anxious depression in a dimensional manner may be the most useful and clinically relevant way of differentiating it from other types of mood and anxiety disorders, and of highlighting the most clinically significant differences between patients with anxious depression versus depression or anxiety alone.

Prevalence of heat and perspiration discomfort inside prostheses: Literature review  

Directory of Open Access Journals (Sweden)

Full Text Available People with limb amputation deal with thermal stresses in their daily activities. Unfortunately, in the majority of this population, all thermal transfer mechanisms, including convection, radiation, evaporation, and conduction, can be disturbed due to the prosthetic socket barrier, decreased body surface area, and/or vascular disease. The thermal environment inside prosthetic sockets, in addition to decreased quality of life and prosthesis use, comfort, and satisfaction, could put people with amputation at high risk for skin irritations. The current review explores the importance of thermal and perspiration discomfort inside prosthetic sockets by providing an insight into the prevalence of the problem. The literature search was performed in two databases, PubMed and Web of Knowledge, to find relevant articles. After considering the review criteria and hand-searching the reference sections of the selected studies, 38 studies were listed for review and data extraction. This review revealed that more than 53% of people with amputation in the selected studies experienced heat and/or perspiration discomfort inside their prostheses. In spite of great technological advances, current prostheses are unable to resolve this problem. Therefore, more attention must be paid by researchers, clinicians, and manufacturers of prosthetic components to thermal-related biomechanics of soft tissues, proper fabrication technique, material selection, and introduction of efficient thermoregulatory systems.

Occupational therapy and return to work: a systematic literature review  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background The primary aim of this review study was to gather evidence on the effectiveness in terms of return to work (RTW of occupational therapy interventions (OTIs in rehabilitation patients with non-congenital disorders. A secondary aim was to be able to select the most efficient OTI. Methods A systematic literature review of peer-reviewed papers was conducted using electronic databases (Cinahl, Cochrane Library, Ebsco, Medline (Pubmed, and PsycInfo. The search focussed on randomised controlled trials and cohort studies published in English from 1980 until September 2010. Scientific validity of the studies was assessed. Results Starting from 1532 papers with pertinent titles, six studies met the quality criteria. Results show systematic reviewing of OTIs on RTW was challenging due to varying populations, different outcome measures, and poor descriptions of methodology. There is evidence that OTIs as part of rehabilitation programs, increase RTW rates, although the methodological evidence of most studies is weak. Conclusions Analysis of the selected papers indicated that OTIs positively influence RTW; two studies described precisely what the content of their OTI was. In order to identify the added value of OTIs on RTW, studies with well-defined OT intervention protocols are necessary.

Effective Teaching in Science: A Review of Literature  

Directory of Open Access Journals (Sweden)

Full Text Available This paper presents a review of literature on effective teaching in science. It tries to explore what constitutes effective teaching in science. According to the literature reviewed, six main principles of effective teaching could be identified. The first is dealing with students' existing ideas and conceptions. This is important for teachers to help students construct their own understanding and knowledge. This requires teachers to help students activate their existing ideas and conceptions, be aware of them and in the light of scientifically accepted knowledge, modify, change or develop them further. For this purpose, such teaching methods and activities as question-and-answer, discussions either small group or whole class, small group activities, practical work, and using ICT facilities can be employed. The second principle is encouraging students to apply new concepts or skills into different contexts. In order to do this, teachers can use practical work, field trips, simulations, writing activities and role-play. The third principle identified is encouraging student participation in lessons. Involvement may be through a wide range of teaching and learning activities such as inquiry-based teaching, co-operative learning groups, questioning, discussions, field trips, role playing and so on. Encouraging student inquiry; encouraging co-operative learning among students; and offering continuous assessment and providing feedback are other principles identified from the literature. The paper discusses how these principles contribute to effective science teaching in science in detail. Finally, the importance of presenting research findings for reform attempts to improve the quality of teaching and learning in Turkish schools is discussed.

Chemistry of the redox sensitive elements. Literature review  

International Nuclear Information System (INIS)

As a part of the safety assessment for a nuclear waste repository, the migration of the radioactive elements from the waste matrix to the biosphere has to be modelled. The geosphere is an important barrier and a consideration of the retention of the radioactive isotopes needs knowledge of sorption coefficients and solubilities. Important long-lived isotopes in the high level radioactive waste are the fission products selenium, technetium, palladium and tin, and the actinide neptunium, which are all redox sensitive elements. A transport model using conservative sorption values predicts mainly doses from these five elements. Since the individual oxidation states of the redox sensitive elements have different and largely unknown sorption properties and solubilities, the realistic doses might be far less. The relevant literature about the chemistry of the five elements is summarized and is planned to serve as the basis for an experimental programme. For every element, the literature about the general chemistry, selected sorption studies, geochemistry, and analytical methods is reviewed. It was found that the knowledge about some of these points is very limited. Even the general chemistry of some of the elements in not well known, because they have only limited applications and research concentrates only on certain aspects. Most of the sorption studies in the context of nuclear waste concentrate on a few of the relevant elements and others have been neglected up to now. The simulation of a realistic system in the laboratory poses some problems, which have to be solved as well. The literature about this subject is also critically reviewed. The elements which are most mobile under realistic far-field conditions are identified and it is recommended to concentrate research on these at the beginning. (author) 9 figs., 192 refs

Negotiating Narratives  

OpenAIRE

With this paper I aim to scrutinise the performance and negotiation of (em)powering narratives and dialogical practices in civil, educational projects between Jews and Palestinian citizens of contemporary Israel. I will discuss to which extent an Arendtian understanding of power as a plural and sharable phenomenon exercised between men/women is useful to understand the narratives challenged and produced in these settings; narratives based on heritage, traditionalism or national discourse, but...

Stereotactic radiosurgery for spinal metastases: a literature review  

International Nuclear Information System (INIS)

Objective: The spine is the most common location for bone metastases. Since cure is not possible, local control and relief of symptoms is the basis for treatment, which is grounded on the use of conventional radiotherapy. Recently, spinal radiosurgery has been proposed for the local control of spinal metastases, whether as primary or salvage treatment. Consequently, we carried out a literature review in order to analyze the indications, efficacy, and safety of radiosurgery in the treatment of spinal metastases. Methods: We have reviewed the literature using the PubMed gateway with data from the Medline library on studies related to the use of radiosurgery in treatment of bone metastases in spine. The studies were reviewed by all the authors and classified as to level of evidence, using the criterion defined by Wright. Results: The indications found for radiosurgery were primary control of epidural metastases (evidence level II), myeloma (level III), and metastases known to be poor responders to conventional radiotherapy – melanoma and renal cell carcinoma (level III). Spinal radiosurgery was also proposed for salvage treatment after conventional radiotherapy (level II). There is also some evidence as to the safety and efficacy of radiosurgery in cases of extramedullar and intramedullar intradural metastatic tumors (level III) and after spinal decompression and stabilization surgery. Conclusion: Radiosurgery can be used in primary or salvage treatment of spinal metasary or salvage treatment of spinal metastases, improving local disease control and patient symptoms. It should also be considered as initial treatment for radioresistant tumors, such as melanoma and renal cell carcinoma. (author)

Factors related to unsuccessful lactogenesis – a literature review  

Directory of Open Access Journals (Sweden)

Full Text Available

The objective of this literature review was to investigate the factors that may interfere in the production of breast milk (lactogenesis, making difficult the establishment of lactation and having hypogalactia as a result. Since breast milk is widely known as the most natural and important food for newborns, it is necessary for nurses to understand and acknowledge the physiological mechanisms involved in lactation in order to help mothers to achieve a successful breastfeeding. Methodology: Two computerized databases were assessed in search for articles: Literature Latin American and Caribbean Health Sciences and Medical Literature and Retrieval System On Line, both covering a 10 years (1997-2007 period. Considering the objective of the study, 21 articles were selected; other academic text-books were also consulted for supporting the development of contents and concepts on lactation physiology. Results: Factors related to failure and/or delay in lactogenesis were: placental retention; deficiency and /or resistance to prolactine; presence of ovarian cysts; breast’s structural alterations; obesity; primiparity; prolonged labor and delivery; cesarean and hypotension. Conclusion: Lactogenesis is a subject that has not been properly acknowledged by nurses, although being essential for the proper establishment of breastfeeding, which is an important issue in nursing care and research. Relevance to clinical practice: When nurses take care of women who experience difficulties on breastfeeding, it is important to consider factors that may interfere in their lactogenesis; this issue seems to be rarely discussed in nursing literature. Therefore, in order to make women’s breastfeeding experience meaningful, enjoyable and effective, nurses should improve their knowledge to investigate factors related to those difficulties and plan interventions. This review is hoped to contribute in raising some aspects that should be addressed in client’s assessment and taken into consideration on planning nursing care.

A narrative review of secondary hazards in hospitals from cases of chemical self-poisoning and chemical exposure.  

Science.gov (United States)

Secondary hazards are an important consideration when dealing with both self-poisoned and chemically contaminated patients. Secondary exposure of hospital staff following the admission of a poisoned patient is relatively rare but potentially serious. Risks usually arise from chemical conversion of a deliberately ingested toxic substance and subsequent offgassing, but there may be toxic substances on the victim or their clothing. Surface contamination is a more common concern in cases where patients have been exposed to chemical releases. This paper presents a
