  1. Evidence-based review of three-dimensional conformal radiotherapy for localized prostate cancer: An ASTRO outcomes initiative

    International Nuclear Information System (INIS)

    Purpose: To perform a systematic review of the evidence to determine the efficacy and effectiveness of three-dimensional conformal radiotherapy (3D-CRT) for localized prostate cancer; provide a clear presentation of the key clinical outcome questions related to the use of 3D-CRT in the treatment of localized prostate cancer that may be answered by a formal literature review; and provide concise information on whether 3D-CRT improves the clinical outcomes in the treatment of localized prostate cancer compared with conventional RT. Methods and Materials: We performed a systematic review of the literature through a structured process developed by the American Society for Therapeutic Radiology and Oncology's Outcomes Committee that involved the creation of a multidisciplinary task force, development of clinical outcome questions, a formal literature review and data abstraction, data review, and outside peer review. Results: Seven key clinical questions were identified. The results and task force conclusions of the literature review for each question are reported. Conclusion: The technological goals of reducing morbidity with 3D-CRT have been achieved. Randomized trials and follow-up of completed trials remain necessary to address these clinical outcomes specifically with regard to patient subsets and the use of hormonal therapy

  2. Fractionation for Whole Breast Irradiation: An American Society for Radiation Oncology (ASTRO) Evidence-Based Guideline

    International Nuclear Information System (INIS)

    Purpose: In patients with early-stage breast cancer treated with breast-conserving surgery, randomized trials have found little difference in local control and survival outcomes between patients treated with conventionally fractionated (CF-) whole breast irradiation (WBI) and those receiving hypofractionated (HF)-WBI. However, it remains controversial whether these results apply to all subgroups of patients. We therefore developed an evidence-based guideline to provide direction for clinical practice. Methods and Materials: A task force authorized by the American Society for Radiation Oncology weighed evidence from a systematic literature review and produced the recommendations contained herein. Results: The majority of patients in randomized trials were aged 50 years or older, had disease Stage pT1-2 pN0, did not receive chemotherapy, and were treated with a radiation dose homogeneity within ±7% in the central axis plane. Such patients experienced equivalent outcomes with either HF-WBI or CF-WBI. Patients not meeting these criteria were relatively underrepresented, and few of the trials reported subgroup analyses. For patients not receiving a radiation boost, the task force favored a dose schedule of 42.5 Gy in 16 fractions when HF-WBI is planned. The task force also recommended that the heart should be excluded from the primary treatment fields (when HF-WBI is used) due to lingering uncertainty regarding late effects of HF-WBI on cardiac function. The task force could not agree on the appropriateness of a tumor bed boost in patients treated with HF-WBI. Conclusion: Data were sufficient to support the use of HF-WBI for patients with early-stage breast cancer who met all the aforementioned criteria. For other patients, the task force could not reach agreement either for or against the use of HF-WBI, which nevertheless should not be interpreted as a contraindication to its use.

    Full Text Available The process of facilitating the uptake of evidence, for example, scientific research findings, into the policymaking process is multifaceted and thus complex. It is therefore important for scientists to understand this process in order to influence it more effectively. Similarly, policymakers need to understand the complexities of the scientific process to improve their interaction with the scientific sphere. This literature review addresses those factors that influence the uptake of scientific evidence into policymaking, the barriers to using science in policymaking, as well as recommendations for improved science–policymaking interaction. A visual diagram of the gears of a car is used to convey the message of the complexities around the engagement between science and policymaking. It is concluded that the issue of evidence-based policymaking remains unresolved and questions for future research on the science–policy interface are raised.

  4. Palliative Radiotherapy for Bone Metastases: An ASTRO Evidence-Based Guideline

    International Nuclear Information System (INIS)

    Purpose: To present guidance for patients and physicians regarding the use of radiotherapy in the treatment of bone metastases according to current published evidence and complemented by expert opinion. Methods and Materials: A systematic search of the National Library of Medicine's PubMed database between 1998 and 2009 yielded 4,287 candidate original research articles potentially applicable to radiotherapy for bone metastases. A Task Force composed of all authors synthesized the published evidence and reached a consensus regarding the recommendations contained herein. Results: The Task Force concluded that external beam radiotherapy continues to be the mainstay for the treatment of pain and/or prevention of the morbidity caused by bone metastases. Various fractionation schedules can provide significant palliation of symptoms and/or prevent the morbidity of bone metastases. The evidence for the safety and efficacy of repeat treatment to previously irradiated areas of peripheral bone metastases for pain was derived from both prospective studies and retrospective data, and it can be safe and effective. The use of stereotactic body radiotherapy holds theoretical promise in the treatment of new or recurrent spine lesions, although the Task Force recommended that its use be limited to highly selected patients and preferably within a prospective trial. Surgical decompression and postoperative radiotherapy is recommended for spinal cord compression or spinal instability in highly selected patients with sufficient performance status and life expectancy. The use of bisphosphonates, radionuclides, vertebroplasty, and kyphoplasty for the treatment or prevention of cancer-related symptoms does not obviate the need for external beam radiotherapy in appropriate patients. Conclusions: Radiotherapy is a successful and time efficient method by which to palliate pain and/or prevent the morbidity of bone metastases. This Guideline reviews the available data to define its proper use

    2016-01-01

    The restoration of proximal surface cavities, originating from Class II carious lesions, to "normal" anatomical specifications is a fundamental objective for the dental practitioner. Cognitive interpretation of tooth morphology attained from evidence-based resources, together with the necessary psychomotor skills for correct design and completion, are considered essential strategies for restoration success. Also, the visualization of the original tooth structure, if present, should substantially benefit the dentist in the creation of a clinically satisfactory restoration. The purpose of this evidence-based review is to define the cause and effect of decisions based on optimum treatment standards of care for the patient. The concepts of form and function, as related to the oral environment, and the consequences of unsatisfactory dental restorative care will be scrutinized. This article will identify and explain the different challenges and solutions for restoration of dental proximal lesions and provide an overview of past, present, and future procedures.

    Rapid eye movement (REM) sleep behavior disorder (RBD) is characterized by dream enactment behavior resulting from a loss of REM skeletal muscle atonia. The neurobiology of REM sleep and the characteristic features of REM atonia have an important basis for understanding the aggravating etiologies the proposed pharmacological interventions in its management. This review outlines the evidence for behavioral and therapeutic measures along with evidence-based guidelines for their implementation, impact on falls, and effect on polysomnography (PSG) while highlighting the non-motor, autonomic, and cognitive impact of this entity. PubMed databases were reviewed upto May 2013 in peer-reviewed scientific literature regarding the pathophysiology and management of RBD in adults. The literature was graded according to the Oxford centre of evidence-based Medicine Levels. An early intervention that helps prevent consequences such as falls and provides a base for intervention with neuroprotective mechanisms and allocates a unique platform that RBD portrays with its high risk of disease conversion with a sufficiently long latency. RBD provides a unique platform with its high risk of disease conversion with a sufficiently long latency, providing an opportunity for early intervention both to prevent consequences such as falls and provide a base for intervention with neuroprotective mechanisms.

    Antiepileptic drugs (AEDs) have many benefits but also many side effects, including aggression, agitation, and irritability, in some patients with epilepsy. This article offers a comprehensive summary of current understanding of aggressive behaviors in patients with epilepsy, including an evidence-based review of aggression during AED treatment. Aggression is seen in a minority of people with epilepsy. It is rarely seizure related but is interictal, sometimes occurring as part of complex psychiatric and behavioral comorbidities, and it is sometimes associated with AED treatment. We review the common neurotransmitter systems and brain regions implicated in both epilepsy and aggression, including the GABA, glutamate, serotonin, dopamine, and noradrenaline systems and the hippocampus, amygdala, prefrontal cortex, anterior cingulate cortex, and temporal lobes. Few controlled clinical studies have used behavioral measures to specifically examine aggression with AEDs, and most evidence comes from adverse event reporting from clinical and observational studies. A systematic approach was used to identify relevant publications, and we present a comprehensive, evidence-based summary of available data surrounding aggression-related behaviors with each of the currently available AEDs in both adults and in children/adolescents with epilepsy. A psychiatric history and history of a propensity toward aggression/anger should routinely be sought from patients, family members, and carers; its presence does not preclude the use of any specific AEDs, but those most likely to be implicated in these behaviors should be used with caution in such cases.

    2016-06-01

    Vitamin E has been demonstrated to modulate cellular signalling, gene expression and affect wounds infected with methicillin-resistant Staphylococcus aureus (MRSA), thus influencing wound healing. This evidence-based review aimed to identify and evaluate current research assessing the properties of vitamin E in relation to wound healing, through its role as an antioxidant and its influence on connective tissue growth factor (CTGF), MRSA and gene transcription. Literature dated from 1996 to 2012, published in English, involving either animals or adult humans with an acute or chronic wound were included. The databases that contained relevant articles were narrowed down to four, and a total of 33 identified studies were included. The literature review revealed that there is a significant dearth of robust studies establishing the effects of vitamin E on wound healing, and further research is clearly warranted. PMID:25124164

    As evidence-based practice has become an important issue in healthcare settings, the educational needs for knowledge and skills for the generation and utilization of healthcare evidence are increasing. Systematic review (SR), a way of evidence generation, is a synthesis of primary scientific evidence, which summarizes the best evidence on a specific clinical question using a transparent, a priori protocol driven approach. SR methodology requires a critical appraisal of primary studies, data extraction in a reliable and repeatable way, and examination for validity of the results. SRs are considered hierarchically as the highest form of evidence as they are a systematic search, identification, and summarization of the available evidence to answer a focused clinical question with particular attention to the methodological quality of studies or the credibility of opinion and text. The purpose of this paper is to introduce an overview of the fundamental knowledge, principals and processes in SR. The focus of this paper is on SR especially for the synthesis of quantitative data from primary research studies that examines the effectiveness of healthcare interventions. To activate evidence-based nursing care in various healthcare settings, the best and available scientific evidence are essential components. This paper will include some examples to promote understandings. PMID:27349664

    Full Text Available Squamous cell carcinoma of head and neck (SCCHN is one of the commonest cancers seen in India, constituting up to 25% of their overall cancer burden. Advanced SCCHN is a bad disease with a poor prognosis and patients usually die of uncontrolled loco-regional disease. Curative intent management of loco-regionally advanced SCCHN has become more evidence-based with active clinical research in the form of large prospective randomized controlled trials and meta-analyses. However, little has been written about palliative radiotherapy (PRT in head and neck cancers. It is widely recognized that PRT provides effective palliation and improved quality-of-life in advanced incurable malignancies. It is in this context that this study proposes to review the existing literature on palliative radiotherapy in advanced incurable SCCHN to help formulate consensus guidelines and recommendations.

    astroEDU is an open access platform for peer-reviewed astronomy education activities. It addresses key problems in educational repositories such as variability in quality, not maintained or updated regularly, limited content review, and more. This is achieved through a peer-review process similar to what scholarly articles are based on. Activities submitted are peer-reviewed by an educator and a professional astronomer which gives the credibility to the activities. astroEDU activities are open-access in order to make the activities accessible to educators around the world while letting them discover, review, distribute and remix the activities. The activity submission process allows authors to learn how to apply enquiry-based learning into the activity, identify the process skills required, how to develop core goals and objectives, and how to evaluate the activity to determine the outcome. astroEDU is endorsed by the International Astronomical Union meaning each activity is given an official stamp by the international organisation for professional astronomers.

  18. [Evidence-Based Review of Laryngeal Cancer Surgery].

    Wiegand, S

    2016-04-01

    Surgical treatment of laryngeal cancer has been established for decades. In addition to total laryngectomy, which was first performed in 1873, a large number of organ preservation surgical techniques, like open partial laryngectomy, transoral laser microsurgery and transoral robotic surgery, have been developed. Studies on laryngeal cancer surgery are mainly retrospective case series and cohort studies. The evolution of chemoradiation protocols and their analysis in prospective randomized trials have led to an increasing acceptance of non-surgical treatment procedures. In addition to an improvement of prognosis, in recent years the preservation of function and maintenance of life quality after primary therapy of laryngeal cancer has increasingly become the focus of therapy planning. Significant late toxicity after chemoradiation has been identified as an important issue. This leads to a reassessment of surgical concepts and initiation of studies on laryngeal cancer surgery which was additionally stimulated by the advent of transoral robotic surgery in the U.S.. Improving the evidence base in laryngeal cancer surgery by successful establishment of surgical trials should be the future goal. PMID:27128401

    The treatment of urinary lithiasis has been revolutionized during the last three decades. Minimally invasive therapies in the form of endoscopic surgery in companion with the advent of shock wave lithotripsy have diminished the role of open stone surgery. Laparoscopy, another minimally invasive treatment, is continuously gaining place in the treatment of urinary stones, mainly replacing open surgery. We have tried to identify the level of the evidence and grade of recommendation, according to the evidence-based medicine criteria, in studies supporting the laparoscopic approach to stone extraction. The highest level of evidence (IIa) was found for laparoscopic ureterolithotomy. It is technically feasible with the advantage of being minimally invasive and having lower postoperative morbidity compared to open ureterolithotomy. It is mostly recommended (grade B) for large impacted stones or when endoscopic ureterolithotripsy or shock wave stone disintegration have failed. Laparoscopic pyelolithotomy is feasible but rarely indicated in the present era (III/B). Laparoscopic nephrolithotomy may be indicated to remove a stone from an anterior diverticulum or when PNL or flexible ureteroscopy have failed (III/B). PMID:20396871

    2012-04-01

    Skype is a popular and free software application that allows PCs and mobile devices to be used for video communication over the Internet. We reviewed the literature to determine whether the clinical use of Skype is supported by evidence. One small (n = 7) controlled clinical trial had assessed the effect of nursing communication using Skype on elderly patients with dementia and their carers. However, we were unable to identify any large, well-designed studies which had formally evaluated the safety, clinical effectiveness, security and privacy of Skype for the routine delivery of patient care. While there were many case reports and small studies, no firm evidence either in favour of, or against the use of Skype for clinical telehealth was found. The risks and benefits of using Skype for clinical purposes are not known. PMID:22362829

    Acute cough caused by viral respiratory tract infections is probably the most common illness to afflict mankind. Despite the widespread but ineffective prescribing of antibiotics, there is no specific therapy. Home remedies and over-the-counter medicines are the mainstay for treatment of this short-lived but debilitating condition where cough is a major troublesome symptom. Across Europe, there are large variations in the recommendations made by healthcare professionals for the treatment of acute cough. This has arisen through custom and practice based on the evidence of historical studies performed to standards well short of what would be considered legitimate today. Acute cough is particularly difficult to study in a controlled setting because of the high rate of spontaneous remission and a large placebo effect. Here we detail the validated modern methodology used to assess the efficacy of antitussives and review the drugs commonly used in Europe against these standards. PMID:27547407

    Since a high intake of fruits and vegetables is inversely related to the incidence of several degenerative diseases, the importance of a balanced diet in relation to human health has received increased consumer attention worldwide. Strawberries (Fragaria X ananassa, Duch.) are a rich source of a wide variety of nutritive compounds such as sugars, vitamins, and minerals, as well as non-nutritive, bioactive compounds such as flavonoids, anthocyanins and phenolic acids. All of these compounds exert a synergistic and cumulative effect on human health promotion and in disease prevention. Strawberry phenolics are indeed able (i) to detoxify free radicals blocking their production, (ii) to modulate the expression of genes involved in metabolism, cell survival and proliferation and antioxidant defense, and (iii) to protect and repair DNA damage. The overall objective of the present review is to update and discuss the key findings, from recent in vivo studies, on the effects of strawberries on human health. Particular attention will be paid to the molecular mechanisms proposed to explain the health effects of polyphenols against the most common diseases related to oxidative stress driven pathologies, such as cancer, cardiovascular diseases, type II diabetes, obesity and neurodegenerative diseases, and inflammation.

    Full Text Available Herbal medicine can be a valuable source of assistance for traditional medicine. There are a number of herbs that can beused in conjunction with modern medicine. Herbs can also be taken to aid recovery from serious diseases. Although one should never aim to treat diseases such as cardiovascular disease solely with herbal medicine, the value of herbs used in tandem with modern medicine cannot be ignored. Saffron has been reported to help lower cholesterol and keep cholesterol levels healthy.Animal studies have shown saffron to lower cholesterol by as much as 50%. Saffron has antioxidant properties; it is, therefore,helpful in maintaining healthy arteries and blood vessels. Saffron is also known to have anti-inflammatory properties, which are beneficial to cardiovascular health. The people of Mediterranean countries, where saffron use is common, have lower than normal incidence of heart diseases. From saffron's cholesterol lowering benefits to its anti inflammatory properties,saffron may be one of the best supplements for cardiac health. This paper reviews the studies regarding the beneficial effects of saffron in cardiovascular health.

    Full Text Available Tourette syndrome (TS is a disorder characterised by multiple motor and vocal tics and is frequently associated with behavioural problems. Tics are known to be affected by internal factors such as inner tension and external factors such as the surrounding environment. A number of behavioural treatments have been suggested to treat the symptoms of TS, in addition to pharmacotherapy and surgery for the most severe cases. This review compiled all the studies investigating behavioural therapies for TS, briefly describing each technique and assessing the evidence in order to determine which of these appear to be effective. Different behavioural therapies that were used included habit reversal training (HRT, massed negative practice, supportive psychotherapy, exposure with response prevention, self-monitoring, cognitive-behavioural therapy, relaxation therapy, assertiveness training, contingency management, a tension-reduction technique and biofeedback training. Overall, HRT is the best-studied and most widely-used technique and there is sufficient experimental evidence to suggest that it is an effective treatment. Most of the other treatments, however, require further investigation to evaluate their efficacy. Specifically, evidence suggests that exposure with response prevention and self-monitoring are effective, and more research is needed to determine the therapeutic value of the other treatments. As most of the studies investigating behavioural treatments for TS are small-sample or single-case studies, larger randomised controlled trials are advocated.

    Full Text Available Contraception is a process or technique for preventing pregnancy by means of medication, device or method that blocks or alters one or more of the processes of reproduction in such a way that sexual union can occur without impregnation. Promotion of family planning is central to the World Health Organization work on improving maternal health and is core to achieve the Millennium Development Goal. It is estimated that 90% of abortion related and 20% of pregnancy related morbidity and mortality, could be prevented by the use of effective contraception. Population explosion is the leading cause of poverty and pollution in developing countries which has detrimental effect on the life supporting system. Hence it is necessary to control the population by the use of contraceptives. Available contraceptives in conventional medicines have many adverse effects. Therefore, there is a need for research of newer, less expensive, less toxic, self-administered, completely reversible contraceptives. Much of these properties are observed in contraceptives as mentioned in classical Unani text. Unani physician has mentioned the various medicines and techniques of contraceptives. Scientific research has confirmed the efficacy of most of the herbal drugs like Ruta graveolans (Suddab, Juniperus communis (Abhal, Piper longum (Filfil daraz, Mentha arvensis (Pudina, Azadirachta indica (Neem, Punica granatum (Anar, Alium cepa (Piyaz and Daucus carota (wild carrot etc. Therefore, the aim of this article is to review the ancient concept of contraception in Unani System of Medicine in the light of available scientific research.

    2010-01-01

    Botanical extracts and single compounds are increasingly used in cosmetics but also in over-the-counter drugs and food supplements. The focus of the present review is on controlled clinical trials with botanicals in the treatment of acne, inflammatory skin diseases, skin infections, UV-induced skin damage, skin cancer, alopecia, vitiligo, and wounds. Studies with botanical cosmetics and drugs are discussed, as well as studies with botanical food supplements. Experimental research on botanicals was considered to a limited extent when it seemed promising for clinical use in the near future. In acne therapy, Mahonia, tea tree oil, and Saccharomyces may have the potential to become standard treatments. Mahonia, Hypericum, Glycyrrhiza and some traditional Chinese medicines appear promising for atopic dermatitis. Some plant-derived substances like dithranol and methoxsalen (8-methoxypsoralen) [in combination with UVA] are already accepted as standard treatments in psoriasis; Mahonia and Capsicum (capsaicin) are the next candidates suggested by present evidence. Oral administration and topical application of antioxidant plant extracts (green and black tea, carotenoids, coffee, and many flavonoids from fruits and vegetables) can protect skin from UV-induced erythema, early aging, and irradiation-induced cancer. Hair loss and vitiligo are also traditional fields of application for botanicals. According to the number and quality of clinical trials with botanicals, the best evidence exists for the treatment of inflammatory skin diseases, i.e. atopic dermatitis and psoriasis. However, many more controlled clinical studies are needed to determine the efficacy and risks of plant-derived products in dermatology. Safety aspects, especially related to sensitization and photodermatitis, have to be taken into account. Therefore, clinicians should not only be informed of the beneficial effects but also the specific adverse effects of botanicals used for dermatologic disorders and

    Full Text Available Introduction: Evidence-based medicine (EBM is the ability and skill in using and integration of the best up-to-date evidences. The aim of this study was a systematic review of barriers, facilities, knowledge and attitude of EBM in Iran. Methods: In this study, database and manual search was used with keywords such as, "evidence-based, EBM, evidence-based nursing, evidence-based practice, evidence-based care, evidence-based activities, evidence-based education" and their combination with the keywords of the barrier, facilitator, attitude, awareness, prospective, knowledge, practice and Iran. The databases of SID (Scientific information database, Magiran, MEDLIB, PubMed, Google scholar, IranMedex and CINAHL (Cumulative index to nursing and allied health literature were used for data collection. Results: Finally, 28 papers were included in this study. The lack of facilities, time and skill in research methodology were the most important barriers to EBM. The most and least important factors were orderly creating ample opportunity and detecting needs and problems. The degree of familiarity with the terminology of evidence-based performance was low (44.2%. The textbooks have been considered as the most significant source of obtaining information. The level of awareness, knowledge, and evidence-based performance was less than 50.0%. Conclusion: There are many various barriers in use of EBM and healthcare providers despite the positive attitude toward EBM had a low level knowledge in EBM setting. Consideration of the importance of EBM proper planning and effective intervention are necessary to removing the barriers and increase the knowledge of healthcare providers.

    2005-01-01

    Reviews integrate the data from original sources of information on the given topic. The quality of the review of literature depends on the quality of initial information. The development of evidence-based medicine demands higher standards from clinical trials. The authors analyse available information on the treatment of erectile dysfunction basing on standard international requirements for clinical trials. A checking list is available for standardization of clinical assessment. The data obtained is ranged by the degree of statistical significance. Basing on the evidence-based approach, the conclusion on efficacy of the following modern drugs in the treatment of erectile dysfunction are made: sildenafil, iochimbin, prostaglandin E1 and tadalafil. The conclusion on efficacy of the other drugs against erectile dysfunction is impossible in view of methodological drawbacks of the trials. PMID:16281837

    Knowledge and skill acquisition related to vascular access are traditionally individual institutional educational initiatives. Australia currently has no national evidence based education programme for renal nurses. A survey of Australian and New Zealand Nephrology Educators' conducted in 2009, identified the need for more effective and consistent delivery of clinical education for nurses using innovative, web-based approaches supporting the tenets of e-learning methodologies. This paper discusses the development, implementation and proposed evaluation of a peer reviewed Australasian e-learning programme on buttonhole cannulation. It will further highlight the benefits of inter-organisational partnerships and how these partnerships can facilitate positive change in teaching and learning practices. This project has unique characteristics that collectively provide value, distinction and innovation to nurses, patients and renal departments. As the e-learning programme was founded on a platform of evidence-based practice it is therefore easily transferable to an international context. PMID:21561547

  5. An evidence based protocol for peer review of radiographer musculoskeletal plain film reporting

    International Nuclear Information System (INIS)

    Aims: Medical image interpretation by non-medically trained staff continues to court controversy. This article aims to show that any potential risks associated with radiographer reporting can be monitored and mitigated if a robust peer review system is introduced. A search of the evidence base illustrates a paucity of guidance on how reporting radiographers should be audited or how a peer review process should be implemented. A practical framework for designing a reporting radiographer peer review process is provided. Methods: Following a literature review, key issues faced when designing a peer review protocol were identified. The following questions are answered: How frequent should peer review take place? How many reports should be reviewed? How are reports selected for review? Who should peer review the radiographer reports? How should radiographer's reporting performance be measured? What standard of reporting is acceptable? Results: Details are provided of the process that has been used for over three years at a busy inner-city teaching hospital for auditing musculoskeletal plain film radiographer reporting. The peer review method presented is not intended to produce robust statistical data; it is a practical method of locally assessing the reporting competency. As such, our protocol should be viewed as part of a larger programme for continuing professional development. Conclusion: It is hoped that this practical protocol will encourage radiology departments to engage in a programme of peer review for reporting radiographers.

    Floaters are a common ocular condition which form as a consequence of aging changes in the vitreous. Although in most patients the symptoms are minimal, they can cause significant impairment in vision-related quality of life in a small population of patients. Recently there has been an increase in awareness of the visual disability caused by floaters, and the evidence-base for treatment of this condition using small-gauge vitrectomy has increased. In this review, we define the term 'floaters' as symptomatic vitreous opacities (SVO). We suggest a classification dependent on the presence or absence of posterior vitreous detachment and discuss their pathogenesis and natural history. We review their impact on patients' quality of life related to visual function. We review the psychological factors that may have a role in some patients who appear to be affected by SVO to the extent that they pursue all options including surgery with all its attendant risks. We summarise the available evidence-base of treatment options available for SVO with special emphasis on the safety and efficacy of vitrectomy for this condition. PMID:26939559

    Clarifying the existing evidence base is crucial to improve the effectiveness of transfusion practice. The UK Systematic Review Initiative has been pursuing this objective primarily through writing systematic reviews on important topics in transfusion medicine. Here, we describe our progress for the past 5 years. We are the only research group that identifies transfusion medicine randomized controlled trials (RCTs) for the Cochrane Central Register of Controlled Trials, and to date, we have contributed 3002 RCT citations. The article considers future challenges including the need for wider involvement from the transfusion medicine community in the process of maintaining and updating systematic reviews and the identification and prioritization of topics for further clinical research including clinical trials. Collaboration between international and local research groups is important if these challenges are to be met. PMID:19320853

    Full Text Available A central retinal vein occlusion (CRVO can induce an ischemic and hypoxic state with resulting sequelae of macular edema and neovascularization. Many treatment options have been studied. Our review aims to investigate the safety and efficacy of the multiple treatment options of CRVO. A PubMed and Cochrane literature search was performed. Well-controlled randomized clinical trials that demonstrated strong level 1 evidence-based on the rating scale developed by the British Centre for Evidence-Based Medicine were included. Seven clinical trials met inclusion criteria to be included in this review. These included studies that investigated the safety and efficacy of retinal photocoagulation (1 study, intravitreal steroid treatment (2 studies, and antivascular endothelial growth factor treatment (4 studies for the treatment of CRVO. In addition, studies evaluating surgical treatment options for CRVO were also included. Many treatment modalities have been demonstrated to be safe and efficacious in the treatment of CRVO. These treatment options offer therapeutic benefits for patients and clinically superior visual acuity and perhaps the quality of life after suffering from a CRVO.

    2011-01-01

    The project „Evidence-based Nursing Education – Preparatory Stage“, funded by the Landesstiftung Baden-Württemberg within the programme Impulsfinanzierung Forschung (Funding to Stimulate Research), aims to collect information on current research concerned with nursing education and to process existing data. The results of empirical research which has already been carried out were systematically evaluated with aim of identifying further topics, fields and matters of interest for empirical research in nursing education. In the course of the project, the available empirical studies on nursing education were scientifically analysed and systematised. The over-arching aim of the evidence-based training approach – which extends beyond the aims of this project - is the conception, organisation and evaluation of vocational training and educational processes in the caring professions on the basis of empirical data. The following contribution first provides a systematic, theoretical link to the over-arching reference framework, as the evidence-based approach is adapted from thematically related specialist fields. The research design of the project is oriented towards criteria introduced from a selection of studies and carries out a two-stage systematic review of the selected studies. As a result, the current status of research in nursing education, as well as its organisation and structure, and questions relating to specialist training and comparative education are introduced and discussed. Finally, the empirical research on nursing training is critically appraised as a complementary element in educational theory/psychology of learning and in the ethical tradition of research. This contribution aims, on the one hand, to derive and describe the methods used, and to introduce the steps followed in gathering and evaluating the data. On the other hand, it is intended to give a systematic overview of empirical research work in nursing education. In order to preserve a

    Full Text Available Last decade has witnessed a spurt in articles focused on the topic of evidence-based medicine (EBM and medical ethics. These articles are not only educative, but draw attention to the changing scenario of medical practice. Surgeons seem a bit less attentive to practice of EBM, more so in the developing world. The theme is now percolating in our realm for demonstrable incorporation of EBM in our practice, which is allegorical of a good physician and is also likely to become demanding legally. In practicing EBM, several conflicts may arise with the ethical vows of medicine. However, majority of these conflicting issues have germinated from a capitalistic approach to medical practice, where the fear of extraneous compulsions dictating prescriptions and procedures in the garb of ′evidence-based practice′ conflicts ethical behaviour. This review shall appraise the reader with important definitions of medical ethics, EBM and how to incorporate best evidence into ones practice. While, EBM brings objectivity to treatment to derive measurable outcomes it should not become regimented or metamorphose as a pseudonym for defensive medicine to escalate treatment costs. EBM also has several limitations one of which is to place the onus on the practicing physician to search for the best evidence and the other is the resource constraint of practice in the developing world. How a plastic surgery practice could be made to conform to evidence based (EB procedures is proposed as insufficient surgical skills can pose a serious threat to not only the practice of EB procedures, but to ethical responsibilities as well. In conclusion, it is necessary to incorporate ethical temperance into EB procedures to withstand societal, peer and legal pressures of current times.

  11. Managing Workplace Violence With Evidence-Based Interventions: A Literature Review.

    Martinez, Angel Johann Solorzano

    2016-09-01

    Workplace violence in health care settings is an occupational issue concerning nurses and other health care professionals. Patient aggression against nurses is often the most common form of violence in clinical settings, occurring in emergency departments, inpatient psychiatric settings, and nursing homes. Physical and verbal assaults are the major forms of workplace violence encountered by nurses. Current research has identified staff, environmental, and patient risk factors as the major precursors of workplace violence initiated by patients. Nurses often experience significant physical and psychological negative consequences after an episode of workplace violence. A review of the evidence was conducted to identify current evidence-based interventions that can help nurses minimize the incidence of workplace violence.

  12. Improving the evidence base for energy policy: The role of systematic reviews

    International Nuclear Information System (INIS)

    The concept of evidence-based policy and practice (EBPP) has gained increasing prominence in the UK over the last 10 years and now plays a dominant role in a number of policy areas, including healthcare, education, social work, criminal justice and urban regeneration. But despite this substantial, influential and growing activity, the concept remains largely unknown to policymakers and researchers within the energy field. This paper defines EBPP, identifies its key features and examines the potential role of systematic reviews of evidence in a particular area of policy. It summarises the methods through which systematic reviews are achieved; discusses their advantages and limitations; identifies the particular challenges they face in the energy policy area; and assesses whether and to what extent they can usefully be applied to contemporary energy policy questions. The concept is illustrated with reference to a proposed review of evidence for a 'rebound effect' from improved energy efficiency. The paper concludes that systematic reviews may only be appropriate for a subset of energy policy questions and that research-funding priorities may need to change if their use is to become more widespread

    2010-09-01

    Full Text Available Abstract Background Teaching of evidence-based medicine (EBM has become widespread in medical education. Teaching the teachers (TTT courses address the increased teaching demand and the need to improve effectiveness of EBM teaching. We conducted a systematic review of assessment tools for EBM TTT courses. To summarise and appraise existing assessment methods for teaching the teachers courses in EBM by a systematic review. Methods We searched PubMed, BioMed, EmBase, Cochrane and Eric databases without language restrictions and included articles that assessed its participants. Study selection and data extraction were conducted independently by two reviewers. Results Of 1230 potentially relevant studies, five papers met the selection criteria. There were no specific assessment tools for evaluating effectiveness of EBM TTT courses. Some of the material available might be useful in initiating the development of such an assessment tool. Conclusion There is a need for the development of educationally sound assessment tools for teaching the teachers courses in EBM, without which it would be impossible to ascertain if such courses have the desired effect.

    Despite the current treatment options for different types of alopecia, there is a need for more effective management options. Recently, low-level laser therapy (LLLT) was evaluated for stimulating hair growth. Here, we reviewed the current evidence on the LLLT effects with an evidence-based approach, focusing more on randomized controlled studies by critically evaluating them. In order to investigate whether in individuals presenting with hair loss (male pattern hair loss (MPHL), female pattern hair loss (FPHL), alopecia areata (AA), and chemotherapy-induced alopecia (CIA)) LLLT is effective for hair regrowth, several databases including PubMed, Google Scholar, Medline, Embase, and Cochrane Database were searched using the following keywords: Alopecia, Hair loss, Hair growth, Low level laser therapy, Low level light therapy, Low energy laser irradiation, and Photobiomodulation. From the searches, 21 relevant studies were summarized in this review including 2 in vitro, 7 animal, and 12 clinical studies. Among clinical studies, only five were randomized controlled trials (RCTs), which evaluated LLLT effect on male and female pattern hair loss. The RCTs were critically appraised using the created checklist according to the Critical Appraisal for Therapy Articles Worksheet created by the Center of Evidence-Based Medicine, Oxford. The results demonstrated that all the performed RCTs have moderate to high quality of evidence. However, only one out of five studies performed intention-to-treat analysis, and only another study reported the method of randomization and subsequent concealment of allocation clearly; all other studies did not include this very important information in their reports. None of these studies reported the treatment effect of factors such as number needed to treat. Based on this review on all the available evidence about effect of LLLT in alopecia, we found that the FDA-cleared LLLT devices are both safe and effective in patients with MPHL and FPHL

    2014-01-01

    The clinical nurse leader (CNL) is a relatively new nursing role, introduced in 2003 through the American Association of Colleges of Nursing (AACN). A narrative review of the extant CNL literature was conducted with the aim of comprehensively summarizing the broad and methodologically diverse CNL evidence base. The review included 25 implementation reports, 1 CNL job analysis, 7 qualitative and/or survey studies, and 3 quantitative studies. All CNL implementation reports and studies described improved care quality outcomes after introduction of the role into a care delivery microsystem. Despite preliminary evidence supporting the CNL as an innovative new nursing role capable of consistently improving care quality wherever it is implemented, CNLs are still struggling to define the role to themselves and to the health care spectrum at large. Although the AACN CNL White Paper provides a concise model for CNL educational curriculum and end competencies, there is a compelling need for further research to substantively delineate the CNL role in practice, define care delivery structures and processes that influence CNL integration, and develop indicators capable of capturing CNL-specific contributions to improved care quality.

    A wide range of pharmacological, surgical, and mechanical pump approaches have been studied to attenuate the systemic inflammatory response to cardiopulmonary bypass, yet no systematically based review exists to cover the scope of anti-inflammatory interventions deployed. We therefore conducted an evidence-based review to capture "self-identified" anti-inflammatory interventions among adult cardiopulmonary bypass procedures. To be included, trials had to measure at least one inflammatory mediator and one clinical outcome, specified in the "Outcomes 2010" consensus statement. Ninety-eight papers satisfied inclusion criteria and formed the basis of the review. The review identified 33 different interventions and approaches to attenuate the systemic inflammatory response. However, only a minority of papers (35 of 98 [35.7%]) demonstrated any clinical improvement to one or more of the predefined outcome measures (most frequently myocardial protection or length of intensive care unit stay). No single intervention was supported by strong level A evidence (multiple randomized controlled trials [RCTs] or meta-analysis) for clinical benefit. Interventions at level A evidence included off-pump surgery, minimized circuits, biocompatible circuit coatings, leukocyte filtration, complement C5 inhibition, preoperative aspirin, and corticosteroid prophylaxis. Interventions at level B evidence (single RCT) for minimizing inflammation included nitric oxide donors, C1 esterase inhibition, neutrophil elastase inhibition, propofol, propionyl-L-carnitine, and intensive insulin therapy. A secondary analysis revealed that suppression of at least one inflammatory marker was necessary but not sufficient to confer clinical benefit. The most effective interventions were those that targeted multiple inflammatory pathways. These observations are consistent with a "multiple hit" hypothesis, whereby clinically effective suppression of the systemic inflammatory response requires hitting multiple

  18. An Evidence-Based Review Literature About Risk Indicators and Management of Unknown-Origin Xerostomia

    Directory of Open Access Journals (Sweden)

    Farzaneh Agha-hosseini

    2013-01-01

    Full Text Available Objective: This evidence-based article reviews risk indicators and management of unknown-origin xerostomia. Xerostomia and hyposalivation refer to different aspects of dry mouth. Xerostomia is a subjective sensation of dry mouth, whilst hyposalivation is defined as an objective assessment of reduced salivary flow rate. About 30% of the elderly (65 years and older experience xerostomia and hyposalivation. Structural and functional factors, or both may lead to salivary gland dysfunction.Study Selection: The EBM literature search was conducted by using the medical literature database MEDLINE via PubMed and OvidMedline search engines. Results were limited to English language articles (1965 to present including clinical trials (CT, randomized controlled trials (RCT, systematic reviews and review articles. Case control or cohort studies were included for the etiology.Results: Neuropathic etiology such as localized oral alteration of thermal sensations, saliva composition change (for example higher levels of K, Cl, Ca, IgA, amylase, calcium, PTH and cortisol, lower levels of estrogen and progesterone, smaller salivary gland size, and illnesses such as lichen planus, are risk indicators for unknown-origin xerostomia. The management is palliative and preventative. Management of symptoms includes drug administration (systemic secretogogues, saliva substitutes and bile secretion-stimulator, night guard, diet and habit modifications. Other managements may be indicated to treat adverse effects.Conclusion: Neuropathic etiology, saliva composition change, smaller salivary gland size, and illnesses such as oral lichen planus can be suggestive causes for unknown-origin xerostomia. However, longitudinal studies will be important to elucidate the causes of unknown-origin xerostomia.

    Nasal irrigation plays a non-negligible role in the treatment of numerous sinonasal pathologies and postoperative care. There is, however, a wide variety of protocols. The present review of the evidence-based literature sought objective arguments for optimization and efficacy. It emerged that large-volume low-pressure nasal douche optimizes the distribution and cleansing power of the irrigation solution in the nasal cavity. Ionic composition and pH also influence mucociliary clearance and epithelium trophicity. Seawater is less rich in sodium ions and richer in bicarbonates, potassium, calcium and magnesium than is isotonic normal saline, while alkaline pH and elevated calcium concentration optimized ciliary motility in vitro. Bicarbonates reduce secretion viscosity. Potassium and magnesium promote healing and limit local inflammation. These results show that the efficacy of nasal irrigation is multifactorial. Large-volume low-pressure nasal irrigation using undiluted seawater seems, in the present state of knowledge, to be the most effective protocol. PMID:26344138

    Full Text Available Context: Around 2.5 million people become infected with HIV each year and its impact on human life and public health can only be tackled and reversed only by sound prevention strategies. Aim: This paper aims to provide the reader about different types of prevention strategies that are effective and practiced in various countries with special emphasis on evidence for success. It also highlights the importance of to the evidence based medicine& strategies. It describes about the importance of combination prevention, which encompasses complementary behavioral, biomedical and structural prevention strategies. Methods & Materials: Searches for peer reviewed journal articles was conducted using the search engines to gather the information from databases of medicine, health sciences and social sciences. Information for each strategy is organized & presented systematically with detailed discussion. Results: For a successful reduction in HIV transmission, there is a great need for combined effects of radical & sustainable behavioral changes among individuals who are potentially at risk. Second, combination prevention is essential for HIV prevention is neither simple nor simplistic. Reductions in HIV transmission need widespread and sustained efforts. A mix of communication channels are essential to disseminate messages to motivate people to engage in various methods of risk reduction. Conclusions: The effect of behavioral strategies could be increased by aiming for many goals that are achieved by use of multilevel approaches with populations both uninfected and infected with HIV.

    Full Text Available Background: Pemphigus, bullous pemphigoid, and epidermolysis bullosa acquisita are autoimmune diseases of skin associated with considerable morbidity and sometimes mortality. There is no cure for these diseases. Aims: To summarize evidence-based treatments for these diseases by performing a systematic review. Methods: The research protocol included the following steps: identification of databases to be searched, defining search strategy, searching the databases for references, first-stage screening of the abstracts, second-stage screening of full texts of articles identified after the first-stage screening, data extraction from the identified articles after second-stage screening, quality appraisal of the studies using the Delphi list, and summarizing the findings. Results: No randomized controlled trials of interventions in pemphigus vegetans, pemphigus erythematosus, and epidermolysis bullosa acquisita could be found. After the second-stage screening, 12 randomized controlled trials were analyzed, which included patients with pemphigus vulgaris or pemphigus vulgaris and pemphigus foliaceus, and 7 which included patients with bullous pemphigoid. Conclusions: Number of high-quality randomized controlled trials conducted on pemphigus and bullous pemphigoid is small. Oral corticosteroid along with a steroid-sparing agent appears to be the most effective treatment for pemphigus. Azathioprine may be most effective as a steroid-sparing agent. Topical corticosteroid therapy (as studied is effective for bullous pemphigoid and appears to be superior to oral corticosteroid for extensive disease. Some suggestions about future research are made.

    Full Text Available Raja GR Edula, Michael F PiccoMayo Clinic, Jacksonville, Florida, USAAbstract: Treatment options for Crohn’s disease have evolved beyond the early goals of induction and remission and are now more focused on preventing complications by altering the natural history of the disease. The advent of biologic therapies has revolutionized the management of Crohn’s disease. Specifically, antibodies to tumor necrosis factor alpha induce rapid mucosal healing. This translates into improved patient outcomes. However, many patients will fail these and other therapies. Natalizumab is a new biologic agent that has been approved for the treatment of moderately to severely active Crohn’s disease in patients who have failed or are intolerant to immunosuppressants and/or tumor necrosis factor inhibitors. It is a selective adhesion molecule inhibitor to alpha-4 integrin resulting in inhibition of the migration of inflammatory cells across the endothelium. This unique mechanism of action has been shown to be effective in the treatment of Crohn’s disease, making it an important option for otherwise refractory patients. Its use has been limited to these refractory patients because of concerns about the development of complications, especially progressive multifocal leukoencephalopathy. In this review, evidence-based data on the indications, efficacy and safety of natalizumab will be presented and its role in the management of patients with Crohn’s disease will be defined.Keywords: Crohn’s disease, natalizumab, alpha-4 integrin

    Full Text Available Adam M Henrie, James J Nawarskas, Joe R Anderson College of Pharmacy, University of New Mexico, Albuquerque, NM, USA Abstract: Pulmonary arterial hypertension (PAH is a chronic and disabling condition characterized by an elevated pulmonary vascular resistance and an elevated mean pulmonary arterial pressure. Despite recent improvements in treatment availability, PAH remains challenging to treat, burdensome for patients, and ultimately incurable. Tadalafil is a phosphodiesterase-5 inhibitor that is administered once daily by mouth for the treatment of PAH. Current treatment guidelines recommend tadalafil as an option for patients with World Health Organization functional class II or III PAH. In a placebo-controlled clinical trial, patients taking tadalafil demonstrated significantly improved exercise capacity as measured by the 6-minute walk distance. Patients also experienced decreased incidence of clinical worsening, increased quality of life, and improved cardiopulmonary hemodynamics. Uncontrolled studies and smaller trials have indicated a possible role for tadalafil as a suitable alternative to sildenafil and as a beneficial add-on option when used in combination with other treatments for PAH. Tadalafil is generally safe and well tolerated. Adverse events are typically mild-to-moderate in intensity, and discontinuation rates are usually low. The purpose of this review is to provide an evidence-based evaluation of the clinical utility of tadalafil in the treatment of PAH. Keywords: tadalafil, phosphodiesterase-5 inhibitor, pulmonary arterial hypertension

    Endurance athletes commonly ingest caffeine as a means to enhance training intensity and competitive performance. A widely-used source of caffeine is coffee, however conflicting evidence exists regarding the efficacy of coffee in improving endurance performance. In this context, the aims of this evidence-based review were threefold: 1) to evaluate the effects of preexercise coffee on endurance performance, 2) to evaluate the effects of coffee on perceived exertion during endurance performance, and 3) to translate the research into usable information for athletes to make an informed decision regarding the intake of caffeine via coffee as a potential ergogenic aid. Searches of three major databases were performed using terms caffeine and coffee, or coffee-caffeine, and endurance, or aerobic. Included studies (n = 9) evaluated the effects of caffeinated coffee on human subjects, provided the caffeine dose administered, administered caffeine ≥ 45 min before testing, and included a measure of endurance performance (e.g., time trial). Significant improvements in endurance performance were observed in five of nine studies, which were on average 24.2% over controls for time to exhaustion trials, and 3.1% for time to completion trials. Three of six studies found that coffee reduced perceived exertion during performance measures significantly more than control conditions (p coffee as an ergogenic aid to improve performance in endurance cycling and running. Coffee providing 3-8.1 mg/kg (1.36-3.68 mg/lb) of caffeine may be used as a safe alternative to anhydrous caffeine to improve endurance performance. PMID:26568580

    Full Text Available [english] The project „Evidence-based Nursing Education – Preparatory Stage“, funded by the Baden-Württemberg within the programme (Funding to Stimulate Research, aims to collect information on current research concerned with nursing education and to process existing data. The results of empirical research which has already been carried out were systematically evaluated with aim of identifying further topics, fields and matters of interest for empirical research in nursing education. In the course of the project, the available empirical studies on nursing education were scientifically analysed and systematised. The over-arching aim of the evidence-based training approach – which extends beyond the aims of this project - is the conception, organisation and evaluation of vocational training and educational processes in the caring professions on the basis of empirical data. The following contribution first provides a systematic, theoretical link to the over-arching reference framework, as the evidence-based approach is adapted from thematically related specialist fields. The research design of the project is oriented towards criteria introduced from a selection of studies and carries out a two-stage systematic review of the selected studies. As a result, the current status of research in nursing education, as well as its organisation and structure, and questions relating to specialist training and comparative education are introduced and discussed. Finally, the empirical research on nursing training is critically appraised as a complementary element in educational theory/psychology of learning and in the ethical tradition of research.This contribution aims, on the one hand, to derive and describe the methods used, and to introduce the steps followed in gathering and evaluating the data. On the other hand, it is intended to give a systematic overview of empirical research work in nursing education. In order to preserve a holistic view of

    Full Text Available IntroductionQuestions are the driving force behind evidence based practice (EBP (Eldredge, 2000. If there were no questions, EBP would be unnecessary. Evidence based practice questions focus on practical real-world problems and issues. The more urgent the question, the greater the need to place it in an EBP context.One of the most challenging aspects of EBP is to actually identify the answerable question. This ability to identify the question is fundamental to then locating relevant information to answer the question. An unstructured collection of keywords can retrieve irrelevant literature, which wastes time and effort eliminating inappropriate information. Successfully retrieving relevant information begins with a clearly defined, well-structured question. A standardized format or framework for asking questionshelps focus on the key elements. Question generation also enables a period of reflection. Is this the information I am really looking for? Why I am looking for this information? Is there another option to pursue first?This paper introduces the first published framework, PICO (Richardson, Wilson, Nishikawa and Hayward, 1995 and some of its later variations including ECLIPSE (Wildridge and Bell, 2002 and SPICE (Booth, 2004. Sample library and information science (LIS questions are provided to illustrate the use of these frameworks to answer questions in disciplines other than medicine.Booth (2006 published a broad overview of developing answerable research questions which also considered whether variations to the original PICO framework were justifiable and worthwhile. This paper will expand on that work.

  1. An evidence based review of proton beam therapy: The report of ASTRO’s emerging technology committee

    International Nuclear Information System (INIS)

    Proton beam therapy (PBT) is a novel method for treating malignant disease with radiotherapy. The purpose of this work was to evaluate the state of the science of PBT and arrive at a recommendation for the use of PBT. The emerging technology committee of the American Society of Radiation Oncology (ASTRO) routinely evaluates new modalities in radiotherapy and assesses the published evidence to determine recommendations for the society as a whole. In 2007, a Proton Task Force was assembled to evaluate the state of the art of PBT. This report reflects evidence collected up to November 2009. Data was reviewed for PBT in central nervous system tumors, gastrointestinal malignancies, lung, head and neck, prostate, and pediatric tumors. Current data do not provide sufficient evidence to recommend PBT in lung cancer, head and neck cancer, GI malignancies, and pediatric non-CNS malignancies. In hepatocellular carcinoma and prostate cancer and there is evidence for the efficacy of PBT but no suggestion that it is superior to photon based approaches. In pediatric CNS malignancies PBT appears superior to photon approaches but more data is needed. In large ocular melanomas and chordomas, we believe that there is evidence for a benefit of PBT over photon approaches. PBT is an important new technology in radiotherapy. Current evidence provides a limited indication for PBT. More robust prospective clinical trials are needed to determine the appropriate clinical setting for PBT.

    Various interventions are used in clinical practice to address insecure or disorganized attachment patterns and attachment disorders. The most common of these are parenting interventions, but not all have a robust empirical evidence base. We undertook a systematic review of randomized trials comparing a parenting intervention with a control, where these used a validated attachment instrument, in order to evaluate the clinical and cost-effectiveness of interventions aiming to improve attachment in children with severe attachment problems (mean age <13 years). This article aims to inform clinicians about the parenting interventions included in our systematic review that were clinically effective in promoting secure attachment. For completeness, we also briefly discuss other interventions without randomized controlled trial evidence, identified in Patient Public Involvement workshops and expert groups at the point our review was completed as being used or recommended. We outline the key implications of our findings for clinical practice and future research. PMID:27583298

    Transfusion medicine has become a large and complex specialty. Although there are now systematic reviews covering many aspects of transfusion, these span a large number of clinical areas and are published across more than a hundred different medical journals, making it difficult for transfusion medicine practitioners and researchers to keep abreast of the current high-level evidence. In response to this problem, NHS Blood and Transplant's Systematic Review Initiative (SRI) has produced a comprehensive overview of systematic reviews in transfusion medicine. A systematic search (to December 2009) and screening procedure were followed by the appraisal of systematic reviews according to predefined inclusion criteria. The 340 eligible systematic reviews were mapped to 10 transfusion intervention groups and 14 topic groups within clinical medicine. Trends in the systematic review literature were examined and gaps in the literature described. The spread of systematic reviews across clinical areas was found to be very uneven, with some areas underreviewed and others with multiple systematic reviews on the same topic, making the identification of the best evidence for current transfusion practice a continuing challenge. References and links to all systematic reviews included in this overview can be freely accessed via the SRI's new online database, the Transfusion Evidence Library (www.transfusionguidelines.org).

    2015-01-01

    Full Text Available Ketamine is a unique anesthetic drug that provides analgesia, hypnosis, and amnesia with minimal respiratory and cardiovascular depression. Because of its sympathomimetic properties it would seem to be an excellent choice for patients with depressed ventricular function in cardiac surgery. However, its use has not gained widespread acceptance in adult cardiac surgery patients, perhaps due to its perceived negative psychotropic effects. Despite this limitation, it is receiving renewed interest in the United States as a sedative and analgesic drug for critically ill-patients. In this manuscript, the authors provide an evidence-based clinical review of ketamine use in cardiac surgery patients for intensive care physicians, cardio-thoracic anesthesiologists, and cardio-thoracic surgeons. All MEDLINE indexed clinical trials performed during the last 20 years in adult cardiac surgery patients were included in the review.

    Full Text Available Background: The health effects of conventional yogurt have been investigated for over a century; however, few systematic reviews have been conducted to assess the extent of the health benefits of yogurt.Objective: The aim of this scoping review was to assess the volume of available evidence on the health effects of conventional yogurt. Methods: The review was guided by a protocol agreed a priori and informed by an extensive literature search conducted in November 2013. Randomized controlled trials were selected and categorized according to the eligibility criteria established in the protocol. Results: 213 studies were identified as relevant to the scoping question. The number of eligible studies identified for each outcome were: bone health (14 studies, weight management and nutrition related health outcomes (81 studies, metabolic health (6 studies; cardiovascular health (57 studies; gastrointestinal health (24 studies; cancer (39 studies; diabetes (13 studies, Parkinson’s disease risk (3 studies, all-cause mortality (3 studies, skin complaints (3 studies, respiratory complaints (3 studies, joint pain/function (2 studies; the remaining 8 studies reported a variety of other outcomes. For studies of a similar design and which assessed the same outcomes in similar population groups, we report the potential for the combining of data across studies in systematic reviews. Conclusions: This scoping review has revealed the extensive evidence base for many outcomes which could be the focus of systematic reviews exploring the health effects of yogurt consumption.

    BACKGROUND: National Health Service (NHS) initiatives such as Clinical Governance, National Service Frameworks and the National Institute of Clinical Excellence (NICE) clinical guidelines programme create demand for tools to enable performance review by healthcare professionals. Ideally such tools should enable clinical teams to assess quality of care and highlight areas of good practice or where improvement is needed. They should also be able to be used to demonstrate progress towards goals ...

    Assessment of quality of life (QoL) is an important, increasingly popular outcome measure in veterinary research and practice, particularly in dogs. In humans, QoL is commonly assessed by self-reporting and since this is not possible for animals, it is crucial that instruments designed to measure QoL are tested for reliability and validity. Using a systematic, replicable literature search strategy, the aim of this study was to find published, peer-reviewed instruments for QoL assessment in dogs and to assess the quality of these. CAB Abstracts and PubMed were searched in July 2013 using terms relevant to dogs, wellbeing and QoL. Inclusion and exclusion criteria were applied. When instruments were not published in full, authors were contacted to obtain them. Criteria were applied to assess the quality, validity and reliability of the 52 instruments obtained. Twenty-seven additional instruments used in peer-reviewed publications were not included because they had not been fully described in the publication or were not provided by authors upon request. Most of the instruments reviewed (48/52) were disease-specific rather than generic. Only four publications provided a definition of QoL or wellbeing. Only 11/52 instruments demonstrated evidence of assessing reliability or validity, and the quality of these instruments was variable. Many novel, unvalidated instruments have been generated and applied as clinical outcomes before it was known whether they measured QoL. This rapid review can be used to identify currently available and validated canine QoL instruments, and to assess the validity and quality of new or existing instruments. PMID:26358965

  20. An evidence-based review for the management of cystic pancreatic lesions

    International Nuclear Information System (INIS)

    The incidental finding of pancreatic cysts is becoming more common because of the increased use of cross-sectional imaging. As a result, the perspective from historical series of symptomatic patients is not always applicable to the current cohort of patients with cystic lesions in their pancreas. In this review, the characteristic radiological features that aid diagnosis are highlighted, and the complementary role of different imaging methods and the appropriate use of tissue sampling are identified. Based on the literature regarding the diagnostic role of imaging in characterizing cystic pancreatic lesions, it is possible to recommend a practical imaging algorithm for the diagnosis of cystic pancreatic lesions

    Full Text Available Elias Jabbour, Jorge Cortes, Hagop KantarjianDepartment of Leukemia, The University of Texas M.D. Anderson Cancer Center, Houston, TX, USAIntroduction: Chronic myelogenous leukemia (CML is a progressive and often fatal hematopoietic neoplasm. The Bcr-Abl tyrosine kinase inhibitor imatinib mesylate represented a major therapeutic advance over conventional CML therapy, with more than 90% of patients obtaining complete hematologic response, and 70%–80% of patients achieving a complete cytogenetic response. Despite the high efficacy of imatinib, a minority of patients in chronic phase CML and more patients in advanced phases are resistant to imatinib, or develop resistance during treatment. This is attributed, in 40% to 50% of cases, to the development of mutations in the Bcr-Abl tyrosine kinase domain that impair imatinib binding. Attempts to circumvent resistance led to the discovery of nilotinib (Tasigna, a novel, potent and selective oral Bcr-Abl kinase inhibitor.Aims: To review the evidence for the use of nilotinib in the management of CML.Evidence review: Preclinical and clinical investigations demonstrate that nilotinib effectively overcomes imatinib resistance, and has further improved the treatment of CML.Place in therapy: Nilotinib is currently indicated for patients with CML in chronic and accelerated phases following imatinib failure. Randomized studies are ongoing to assess the efficacy of nilotinib in patients with newly diagnosed CML.Keywords: CML, tyrosine kinase inhibitors, nilotinib, imatinib-resistance, imatinibintolerance.

    2000-01-01

    A review of the available evidence for the associations between environmental sanitation and transmission of trachoma was undertaken with a view to identifying preventive interventions. The WHO Global Alliance for the Elimination of Trachoma by the Year 2020 (GET2020) has adopted the "SAFE" strategy, consisting of four components: Surgery, Antibiotic treatment, promotion of Facial cleanliness and initiation of Environmental changes. This review of 19 studies selected from the 39 conducted in different parts of the world shows that there is clear evidence to support the recommendation of facial cleanliness and environmental improvements (i.e. the F and E components of the SAFE strategy) to prevent trachoma. Person-to-person contact and flies appear to constitute the major transmission pathways. Improvement of personal and community hygiene has great potential for a sustainable reduction in trachoma transmission. Controlled clinical trials are needed to estimate the relative contribution of various elements to the risk of transmission of trachoma and the effectiveness of different interventions. These could show the relative attributable risks and effectiveness of interventions to achieve improvement of personal hygiene and fly control by environmental improvements, alone or in combination, and with or without antibiotic treatment.

    2011-01-01

    Full Text Available Spinal metastasis is a problem that afflicts many cancer patients. Traditionally, conventional fractionated radiation therapy and/or surgery have been the most common approaches for managing such patients. Through technical advances in radiotherapy, high dose radiation with extremely steep drop off can now be delivered to a limited target volume along the spine under image-guidance with very high precision. This procedure, known as stereotactic body radiosurgery, provides a technique to rapidly treat selected spinal metastasis patients with single- or limited-fraction treatments that have similar to superior efficacies compared with more established approaches. This review describes current treatment systems in use to deliver stereotactic body radiosurgery as well as results of some of the larger case series from a number of institutions that report outcomes of patients treated for spinal metastatic disease. These series include nearly 1400 patients and report a cumulative local control rate of 90% with myelopathy risk that is significantly less than 1%. Based on this comprehensive review of the literature, we believe that stereotactic body radiosurgery is an established treatment modality for patients with spinal metastatic disease that is both safe and highly effective.

    Background. Chronic low back pain (CLBP) among nurses is a growing health concern. The multimodal nature of mind-body exercises has potential to impact physiological and psychological processes associated with chronic pain, affording possible advantages over conventional unimodal therapies. This paper summarizes the prevalence of and risk factors for CLBP among nurses, reviews the effectiveness in treating pain and disability of mind-body exercises (yoga and tai chi) for CLBP among the general and nursing population, and describes implications. Methods. Articles, published during or prior to 2015, were systematically identified through the PubMed/MEDLINE, Web of Science, and ScienceDirect databases using the following search terms: nurses, mind-body, integrative, biopsychosocial, yoga, tai chi, back pain, and/or risk factors. Results. Prevalence estimates of CLBP among nurses ranged from 50% to 80%. Associated risk factors for CLBP included lifestyle and physical, psychological, psychosocial, and occupational factors. No published studies were identified that evaluated yoga or tai chi for nurses with CLBP. Studies in the general population suggested that these interventions are effective in reducing pain and disability and may improve factors/processes predictive of CLBP. Conclusion. This review suggests that evaluating the impact of multimodal interventions such as yoga and tai chi for nurses with CLBP warrants investigation. PMID:27446610

    Full Text Available The purpose of this systematic review was to address the treatment of rotator cuff tears by applying tissue engineering approaches to improve tendon healing, specifically platelet rich plasma (PRP augmentation, stem cells, and scaffolds. Our systematic search was performed using the combination of the following terms: “rotator cuff”, “shoulder”, “PRP”, “platelet rich plasma”, “stemcells”, “scaffold”, “growth factors”, and “tissue engineering”. No level I or II studies were found on the use of scaffolds and stem cells for rotator cuff repair. Three studies compared rotator cuff repair with or without PRP augmentation. All authors performed arthroscopic rotator cuff repair with different techniques of suture anchor fixation and different PRP augmentation. The three studies found no difference in clinical rating scales and functional outcomes between PRP and control groups. Only one study showed clinical statistically significant difference between the two groups at the 3-month followup. Any statistically significant difference in the rates of tendon rerupture between the control group and the PRP group was found using the magnetic resonance imaging. The current literature on tissue engineering application for rotator cuff repair is scanty. Comparative studies included in this review suggest that PRP augmented repair of a rotator cuff does not yield improved functional and clinical outcome compared with non-augmented repair at a medium and long-term followup.

    Oncology education can impact nursing students' attitudes toward oncology and their interest in oncology nursing. To explore that relationship, a literature search was conducted using the CINAHL®, Cochrane Library, ERIC®, PubMed, and Scopus® databases. Nineteen pertinent studies were incorporated into the review, and recommendations were graded by strength of evidence schemas. The reviewed literature indicated undergraduate oncology education may be effective in encouraging nursing students to consider oncology as a practice area. Negative attitudes toward oncology such as fear and pessimism often are seen in students and practicing nurses. Educational interventions for students and nurses are effective in increasing knowledge and skills that are instrumental in fostering confidence and positive attitudes toward oncology nursing. All nursing students should have organized, mandatory clinical and didactic oncology nursing education experiences. Additional research is needed to support the effectiveness of educational strategies in influencing students' intent to practice oncology nursing. Innovative strategies including nontraditional clinical experiences, internships, fellowships, high-fidelity simulation, and postgraduate residencies are needed to provide adequate educational opportunities for nursing students to foster a strong and proficient oncology nursing workforce.

    Full Text Available Objective. To review the literature on fat modifying dietary supplements commonly used for weight loss. Methods. Recently published randomized, placebo-controlled trials were identified in PubMed, MEDLINE, International Pharmaceutical Abstracts, Cochrane Database, and Google Scholar using the search terms dietary supplement, herbal, weight loss, obesity, and individual supplement names. Discussion. Data for conjugated linoleic acid (CLA, Garcinia cambogia, chitosan, pyruvate, Irvingia gabonensis, and chia seed for weight loss were identified. CLA, chitosan, pyruvate, and Irvingia gabonensis appeared to be effective in weight loss via fat modifying mechanisms. However, the data on the use of these products is limited. Conclusion. Many obese people use dietary supplements for weight loss. To date, there is little clinical evidence to support their use. More data is necessary to determine the efficacy and safety of these supplements. Healthcare providers should assist patients in weighing the risks and benefits of dietary supplement use for weight loss.

    Full Text Available Brendan T Bowman, Mitchell H Rosner Division of Nephrology, University of Virginia Health System, Charlottesville, VA, USA Abstract: Hyponatremia is the most common electrolyte abnormality seen in clinical practice. Most cases of euvolemic or hypervolemic hyponatremia involve arginine vasopressin (AVP. AVP leads to a concentrated urine and negative free water clearance. Given this primary role of AVP, antagonizing its effect through blockade of its receptor in the distal tubule is an attractive therapeutic target. Lixivaptan is a newer, non-peptide, vasopressin type 2 receptor antagonist. Recent studies have demonstrated efficacy. This review summarizes the clinical pharmacology and data for this new agent.

    2014-09-01

    There have been no comprehensive reviews of the relation of breakfast cereal consumption to nutrition and health. This systematic review of all articles on breakfast cereals to October 2013 in the Scopus and Medline databases identified 232 articles with outcomes related to nutrient intake, weight, diabetes, cardiovascular disease, hypertension, digestive health, dental and mental health, and cognition. Sufficient evidence was available to develop 21 summary evidence statements, ranked from A (can be trusted to guide practice) to D (weak and must be applied with caution). Breakfast cereal consumption is associated with diets higher in vitamins and minerals and lower in fat (grade B) but is not associated with increased intakes of total energy or sodium (grade C) or risk of dental caries (grade B). Most studies on the nutritional impact are cross-sectional, with very few intervention studies, so breakfast cereal consumption may be a marker of an overall healthy lifestyle. Oat-, barley-, or psyllium-based cereals can help lower cholesterol concentrations (grade A), and high-fiber, wheat-based cereals can improve bowel function (grade A). Regular breakfast cereal consumption is associated with a lower body mass index and less risk of being overweight or obese (grade B). Presweetened breakfast cereals do not increase the risk of overweight and obesity in children (grade C). Whole-grain or high-fiber breakfast cereals are associated with a lower risk of diabetes (grade B) and cardiovascular disease (grade C). There is emerging evidence of associations with feelings of greater well-being and a lower risk of hypertension (grade D), but more research is required. PMID:25225349

    AIM: To identify the newest approaches to type 2 diabetes (T2DM) prevention and control in the developing world context. METHODS: We conducted a systematic review of published studies of diabetes prevention and control programs in low and middle-income countries, as defined by the World Bank. We searched PubMed using Medical Subject Headings terms. Studies needed to satisfy four criteria: (1) Must be experimental; (2) Must include patients with T2DM or focusing on prevention of T2DM; (3) Must have a lifestyle intervention component; (4) Must be written in English; and (5) Must have measurable outcomes related to diabetes. RESULTS: A total of 66 studies from 20 developing countries were gathered with publication dates through September 2014. India contributed the largest number of trials (11/66). Of the total 66 studies reviewed, all but 3 studies reported evidence of favorable outcomes in the prevention and control of type 2 diabetes. The overwhelming majority of studies reported on diabetes management (56/66), and among these more than half were structured lifestyle education programs. The evidence suggests that lifestyle education led by allied health professionals (nurses, pharmacists) were as effective as those led by physicians or a team of clinicians. The remaining diabetes management interventions focused on diet or exercise, but the evidence to recommend one approach over another was weak. CONCLUSION: Large experimental diabetes prevention/control studies of dietary and exercise interventions are lacking particularly those that consider quality rather than quantity of carbohydrates and alternative exercise.

    Full Text Available Daniel Z Lieberman, Suena H MasseyDepartment of Psychiatry and Behavioral Sciences, George Washington University School of Medicine and Health Sciences, Washington, DC, USAIntroduction: Desvenlafaxine, the active metabolite of venlafaxine, is a serotonin norepinephrine reuptake inhibitor (SNRI recently approved for the treatment of major depressive disorder. It is one of only three medications in this class available in the United States.Aims: The objective of this article is to review the published evidence for the safety and efficacy of desvenlafaxine, and to compare it to other antidepressants to delineate its role in the treatment of depression.Evidence review: At the recommended dose of 50 mg per day the rate of response and remission was similar to other SNRIs, as was the adverse effect profile. The rate of discontinuation was no greater than placebo, and a discontinuation syndrome was not observed at this dose. Higher doses were not associated with greater efficacy, but they did lead to more side effects, and the use of a taper prior to discontinuation. The most common side effects reported were insomnia, somnolence, dizziness, and nausea. Some subjects experienced clinically significant blood pressure elevation.Place in therapy: Like duloxetine, desvenlafaxine inhibits the reuptake of both norepinephrine and serotonin at the starting dose. Dual reuptake inhibitors have been shown to have small but statistically significantly greater rates of response and remission compared to selective serotonin reuptake inhibitors, and they have also shown early promise in the treatment of neuropathic pain. Desvenlafaxine may prove to be a valuable treatment option by expanding the limited number of available dual reuptake inhibitors.Keywords: desvenlafaxine, depression, reuptake inhibitors, norepinephrine, serotonin

    Full Text Available William WinlowCore Medical Publishing, Knutsford, UKIntroduction: Restless legs syndrome (RLS affects 5–15% of adults, but is often unrecognized and consequently misdiagnosed. The International Restless Legs Scale (IRLS has been developed and validated to assess the severity of RLS. Currently, the most common treatment for RLS is levodopa, but this may lead to augmentation of symptoms. Pramipexole has been developed as an alternative treatment for patients diagnosed with RLS.Aims: The objective of this article is to review the evidence of the effectiveness of pramipexole for the clinical management of patients with RLS.Evidence review: There is clear evidence that pramipexole reduces the leg movements associated with RLS, as measured by improvements in both the IRLS and the Clinical Global Impression (CGI score. There is also moderate evidence that the drug improves sleep quality. Pramipexole clearly improves the anxiety and depression often associated with RLS. Augmentation may be associated with pramipexole treatment, but the evidence is contradictory and augmentation may be more associated with patients pretreated with levodopa or with patients with primary RLS rather than those with secondary RLS. Pramipexole therapy appears to be well tolerated, with only mild-to-moderate adverse events reported.Outcomes summary: Pramipexole reduces leg movements in RLS, and is well tolerated. Further investigation is required to confirm the preliminary evidence that pramipexole restores normal sleep architecture and restores a normal quality of life in patients with RLS. Health economic studies would be valuable in demonstrating the true impact of pramipexole on the social burden of RLS.Key words: restless legs syndrome (RLS, pramipexole, outcomes, evidence

    Full Text Available Garlic has been used since time immemorial as a culinary spice and medicinal herb. Garlic has been cultivated in the Middle East for more than 5,000 years and has been an important part of traditional Chinese medicine. The region with the largest commercial garlic production is central California. China is also a supplier of commercial garlic. The bulb is used medicinally. Garlic has been touted as an herb with numerous health benefits, from treating the common cold to serving as an anticancer agent. Research has proven that garlic is beneficial for those with hypertension. By thinning the blood garlic can lower blood pressure by 5 to 10 percent. It can also lower cholesterol and discourage clot formation. The sulfur compound allicin, produced by crushing or chewing fresh garlic or by taking powdered garlic products with allicin potential, in turn produces other sulfur compounds: ajoene, allyl sulfides, and vinyldithiins. Aged garlic products lack allicin, but may have activity due to the presence of S-allylcysteine. In this review, we focused on the cardiovascular effects of garlic.

    The purpose of the study was to review the current evidence and design a diabetic macular edema (DME) management guideline specific for India. The published DME guidelines from different organizations and publications were weighed against the practice trends in India. This included the recently approved drugs. DME management consisted of control of diabetes and other associated systemic conditions, such as hypertension and hyperlipidemia, and specific therapy to reduce macular edema. Quantification of macular edema is precisely made with the optical coherence tomography and treatment options include retinal laser, intravitreal anti-vascular endothelial growth factors (VEGF), and implantable dexamethasone. Specific use of these modalities depends on the presenting vision and extent of macular involvement. Invariable eyes with center-involving macular edema benefit from intravitreal anti-VEGF or dexamethasone implant therapy, and eyes with macular edema not involving the macula center benefit from retinal laser. The results are illustrated with adequate case studies and frequently asked questions. This guideline prepared on the current published evidence is meant as a guideline for the treating physicians.

    Nursing shortages exist worldwide while job stress, dissatisfaction, lack of peer support and limited professional opportunities still contribute to attrition. The aim of this systematic review is to describe and evaluate the quality of the science, report recommendations and lessons learned about implementing and evaluating nurse residency programs (NRPs) designed to improve new graduate transitioning. Databases were searched between 1980 and 2010 using five search terms: nurse, intern, extern, transition and residency programs. Twenty studies reporting programs for new RNs fit the inclusion criteria. Three major discoveries include: 1. Wide variation in content, teaching and learning strategies make comparison across programs difficult; 2. Lack of theory in designing the educational intervention has limited the selection and development of new instruments to measure program effectiveness; and 3. Well designed quasi-experimental studies are needed. As a major nursing education redesign, NRPs could be used to test the principles, concepts and strategies of organizational transformation and experiential-interactive learning theory. By focusing on fiscal outcomes, current administrators of NRPs are missing the opportunity to implement an organizational strategy that could improve workplace environments. Healthcare organizations need to envision NRPs as a demonstration of positive clinical learning environments that can enhance intra- and interprofessional education and practice. PMID:22818190

    The inferior alveolar nerve (IAN) and lingual (LN) are susceptible to iatrogenic surgical damage. Systematically review recent clinical evidence regarding IAN/LN repair methods and to develop updated guidelines for managing injury. Recent publications on IAN/LN microsurgical repair from Medline, Embase and Cochrane Library databases were screened by title/abstract. Main texts were appraised for exclusion criteria: no treatment performed or results provided, poor/lacking procedural description, cohort injury type, injury timing, neurosensory disturbances and intra-operative findings. Best functional nerve recovery occurred after direct apposition and suturing if nerve ending gaps were nerve grafting (sural/greater auricular nerve). Timing of microneurosurgical repair after injury remains debated. Most authors recommend surgery when neurosensory deficit shows no improvement 90 days post-diagnosis. Nerve transection diagnosed intra-operatively should be repaired in situ; minor nerve injury repair can be delayed. No consensus exists regarding optimal methods and timing for IAN/LN repair. We suggest a schematic guideline for treating IAN/LN injury, based on the most current evidence. We acknowledge that additional RCTs are required to provide definitive confirmation of optimal treatment approaches. PMID:26059454

    Pulmonary arterial hypertension (PAH) remains a progressive disease without a cure, despite the development of several treatment options over the past several decades. Its management strategy consists of the endothelin receptor antagonists (ambrisentan, bosentan, macitentan), phosphodiesterase-5 inhibitors (sildenafil, tadalafil, vardenafil), and prostacyclin analogs (epoprostenol, treprostinil, iloprost). Treprostinil, a stable prostacyclin analog, displays vasodilatory effects in the pulmonary vasculature, as well as antiplatelet aggregation properties. Clinical practice guidelines recommend oral endothelin receptor antagonist or phosphodiesterase inhibitor therapy in mild to moderate PAH. Epoprostenol is specifically suggested as first-line therapy in moderate to severe PAH patients (ie, World Health Organization/New York Heart Association functional class III-IV). However, treprostinil may be an alternative option in these severe PAH patients. The longer half-life and stability at room temperature with treprostinil may be associated with lower risk of pulmonary hemodynamic worsening as a result of abrupt infusion discontinuation and less frequent drug preparation. These characteristics make treprostinil an attractive alternative to continuous infusion of epoprostenol, due to convenience and patient safety. The purpose of this review is to evaluate the safety and efficacy of continuous infusion of treprostinil as well as the inhaled and oral routes of administration in PAH. PMID:25018685

    Full Text Available McCarty EJ, Dinsmore WWDepartment of Genitourinary Medicine, Royal Victoria Hospital, Belfast, IrelandAbstract: Premature ejaculation (PE is a major issue in male sexual health. The global prevalence of PE is estimated to be between 20% and 40%, making it the most common sexual dysfunction in men. PE causes distress and reduced quality of life for patients and has a negative impact on interpersonal relationships. Historically, it has been treated with cognitive therapy, behavioral methods, and off-label use of selective serotonin reuptake inhibitors usually used to treat depression and other psychological disorders. Dapoxetine is a selective serotonin reuptake inhibitor specifically designed to treat PE. This paper reviews the current evidence for use of dapoxetine in the treatment of PE in adult men. There is substantial evidence that dapoxetine 30 mg or 60 mg taken “on-demand” results in a significant increase in intravaginal ejaculatory latency time when compared with placebo. Patient-reported outcomes are clearly improved relative to placebo following dapoxetine therapy, indicating greater control over ejaculation, more satisfaction with intercourse, less ejaculation-related distress, and, importantly, significantly reduced interpersonal difficulty. These data were supported by consistent reports of improvement in Clinical Global Impression of change in PE following treatment with dapoxetine. Further studies are needed to evaluate long-term efficacy and health economics. The unique pharmacology of dapoxetine makes it ideal for on-demand dosing, and the clinical evidence shows dapoxetine to be an efficacious and tolerable treatment for lifelong and acquired PE.Keywords: dapoxetine, intravaginal ejaculatory latency time, patient-reported outcomes, premature ejaculation

    Burn injury can be inflicted intentionally either by one person to another whenever one has the ability to physically control the other, or it can be self-inflicted. There is scant evidential basis for much that is written about and practiced in the evaluation and care of patients that have sustained intentional burn injuries. Yet this is an area in which medical personnel must necessarily be trained in both the therapeutic and forensic aspects of a complex problem. Failure to appreciate the complexity of medical and forensic interactions may have far reaching effects. A missed diagnosis can result in inappropriate medical care, on-going abuse and future fatality. Inept management can result on the one hand, in blame levelled inappropriately placing incomparable strain on family units and innocent parties, and on the other, allow abusers to continue unchecked. This is the first review on the subject in which lawyers and doctors collaborate to produce a holistic approach to this subject. In it we describe the legal considerations that medical staff must appreciate when approaching patients who may have suffered intentional burns. We analyse the various scenarios in which intentional burning can be found and challenge the clinical dogma with much of the management of paediatric inflicted burns has become imbued. We suggest a rational and balanced approach to all intentional burn injuries-especially when children are involved. In the light of current case law in which dogmatic medical evidence has been implicated in wrongful convictions for child abuse in the UK, it is imperative that medical professionals gather evidence carefully and completely and apply it with logic and impartiality. This paper will aid clinicians who may not be experienced in dealing with burn injuries, but find themselves in the position of seeing a burn acutely, to avoid common mistakes. PMID:15475134

Its management strategy consists of the endothelin receptor antagonists (ambrisentan, bosentan, macitentan, phosphodiesterase-5 inhibitors (sildenafil, tadalafil, vardenafil, and prostacyclin analogs (epoprostenol, treprostinil, iloprost. Treprostinil, a stable prostacyclin analog, displays vasodilatory effects in the pulmonary vasculature, as well as antiplatelet aggregation properties. Clinical practice guidelines recommend oral endothelin receptor antagonist or phosphodiesterase inhibitor therapy in mild to moderate PAH. Epoprostenol is specifically suggested as first-line therapy in moderate to severe PAH patients (ie, World Health Organization/New York Heart Association functional class III–IV. However, treprostinil may be an alternative option in these severe PAH patients. The longer half-life and stability at room temperature with treprostinil may be associated with lower risk of pulmonary hemodynamic worsening as a result of abrupt infusion discontinuation and less frequent drug preparation. These characteristics make treprostinil an attractive alternative to continuous infusion of epoprostenol, due to convenience and patient safety. The purpose of this review is to evaluate the safety and efficacy of continuous infusion of treprostinil as well as the inhaled and oral routes of administration in PAH.Keywords: treprostinil, prostacyclin, pulmonary arterial

    Ongoing debates surrounding Open Access to the scholarly literature are multifaceted and complicated by disparate and often polarised viewpoints from engaged stakeholders. At the current stage, Open Access has become such a global issue that it is critical for all involved in scholarly publishing, including policymakers, publishers, research funders, governments, learned societies, librarians, and academic communities, to be well-informed on the history, benefits, and pitfalls of Open Access. In spite of this, there is a general lack of consensus regarding the potential pros and cons of Open Access at multiple levels. This review aims to be a resource for current knowledge on the impacts of Open Access by synthesizing important research in three major areas: academic, economic and societal. While there is clearly much scope for additional research, several key trends are identified, including a broad citation advantage for researchers who publish openly, as well as additional benefits to the non-academic dissemination of their work. The economic impact of Open Access is less well-understood, although it is clear that access to the research literature is key for innovative enterprises, and a range of governmental and non-governmental services. Furthermore, Open Access has the potential to save both publishers and research funders considerable amounts of financial resources, and can provide some economic benefits to traditionally subscription-based journals. The societal impact of Open Access is strong, in particular for advancing citizen science initiatives, and leveling the playing field for researchers in developing countries.

Currently, there is no single standard therapy, with choice of treatment dependent on individual patient factors. Lenalidomide is an immunomodulatory drug with potent antitumor, antiangiogenic, immunomodulatory, and proapoptotic activity in MM.Aims: To evaluate the evidence for the use of lenalidomide in its current indication in relapsed or refractory MM, and additionally its investigational use for the treatment of newly diagnosed MM.Evidence review: In patients with relapsed and refractory MM, adding lenalidomide to high-dose dexamethasone significantly improves response rates and time-to-progression, relative to high-dose dexamethasone alone. This translates into a significant extension of overall survival (with a median extension of 9.1 months in a pivotal phase III study. Outcome is independent of patient age, number of previous therapies, type of previous therapy (including thalidomide or autologous stem cell transplantation, renal impairment, and β2-microglobulin level. Evidence suggests that combining lenalidomide with low-dose dexamethasone improves outcomes in patients with newly diagnosed disease and is superior to lenalidomide combined with highdose dexamethasone. Myelosuppression is the predominant toxicity observed, although some studies have shown high incidences of venous thromboembolism in the absence of prophylactic antithrombotic anticoagulation therapy. There is currently only limited evidence regarding the health economics of lenalidomide.Role in therapy: The encouraging results obtained with lenalidomide alone and in combination with dexamethasone

Current guidelines recommend individualized treatment plans which allow for provider choice and diversity of pharmacotherapeutic regimens. The glucagon-like peptide-1 receptor agonist (GLP-1 RA class is rapidly expanding, with dulaglutide (Trulicity™ as a once-weekly agent recently approved. Aims: This article examines the evidence currently available on the efficacy and safety of dulaglutide for use in T2DM. Evidence review: Dulaglutide has been shown to have similar efficacy and safety to other newer GLP-1 RAs, and better glycemic control than placebo. It lowers glycated hemoglobin (A1c, fasting and postprandial glucose levels, and promotes weight loss when used as first-, second-, or third-line therapy. It has also been shown to improve β-cell function and provide cardiovascular benefits, such as lower blood pressure and improved lipid levels. Dulaglutide also has a low risk for hypoglycemia and a similar adverse effect profile to other GLP-1 RAs in the class, with transient gastrointestinal problems and potential risk for pancreatitis. Place in therapy: While long-term data on safety and efficacy are forthcoming, dulaglutide is positioned to be placed at the same level as other GLP-1 RAs in the class: as second-line therapy in addition to diet and exercise in those patients who cannot achieve glycemic control on monotherapy metformin. It may also be useful as first-line therapy instead of metformin. Conclusion: Dulaglutide is a once-weekly GLP-1 RA

Methods: Literature search was conducted according to evidence based on methodology review at Trip database, National Guideline Clearinghouse, Guidelines finder, Cochrane Library, Dare, Bandolier and Medline, as well as using the MeSH index terms “Irritable bowel syndrome” and “peppermint oil”. We selected practice guidelines, systematic reviews, meta-analysis and randomized controlled trials that evaluated peppermint oil (PO efficacy in improving symptoms and/or quality of life when compared to placebo or other approved therapy for IBS. Results and Discussion: A total of eight articles were selected including five practice guidelines and three systematic reviews/ meta-analysis. Existing evidence suggests that there are enough data to support the use of peppermint oil in IBS for overall symptomatic relief, especially when abdominal pain is the dominant symptom, when compared to placebo (with an odds ratio of 2.7; CI 95%, 1.6 to 4.8 and NNT of 3. There is also evidence regarding overall quality of life improvement when using PO compared to placebo (p<0.001. Conclusion: So far, evidence suggests that PO should be considered for IBS patients, especially in the presence of abdominal pain (Strength of recommendation B. However, more high methodological quality studies that evaluate long-term efficacy and security of PO are needed.

  8. Approved and investigational uses of modafinil : an evidence-based review.

    Modafinil is a wake-promoting agent that is pharmacologically different from other stimulants. It has been investigated in healthy volunteers, and in individuals with clinical disorders associated with excessive sleepiness, fatigue, impaired cognition and other symptoms. This review examines the use of modafinil in clinical practice based on the results of randomized, double-blind, placebo-controlled clinical trials available in the English language in the MEDLINE database. In sleep-deprived individuals, modafinil improves mood, fatigue, sleepiness and cognition to a similar extent as caffeine but has a longer duration of action. Evidence for improved cognition in non-sleep-deprived healthy volunteers is controversial.Modafinil improves excessive sleepiness and illness severity in all three disorders for which it has been approved by the US FDA, i.e. narcolepsy, shift-work sleep disorder and obstructive sleep apnoea with residual excessive sleepiness despite optimal use of continuous positive airway pressure (CPAP). However, its effects on safety on the job and on morbidities associated with these disorders have not been ascertained. Continued use of CPAP in obstructive sleep apnoea is essential. Modafinil does not benefit cataplexy.In very small, short-term trials, modafinil improved excessive sleepiness in patients with myotonic dystrophy. It was efficacious in fairly large studies of attention deficit hyperactivity disorder (ADHD) in children and adolescents, and was as efficacious as methylphenidate in a small trial, but has not been approved by the FDA, in part because of its serious dermatological toxicity. In a trial of 21 non-concurrent subjects, with 2-week treatment periods, modafinil was as effective as dexamfetamine in adult ADHD. Modafinil was helpful for depressive symptoms in bipolar disorder in a trial that excluded patients with stimulant-induced mania. A single dose of modafinil may hasten recovery from general anaesthesia after day surgery. A

    Full Text Available Abstract Background Interventions to promote positive parenting are often reported to offer good outcomes for children but they can consume substantial resources and they require rigorous appraisal. Methods Evaluations of the Triple P parenting program were subjected to systematic review and meta-analysis with analysis of biases. PsychInfo, Embase and Ovid Medline were used as data sources. We selected published articles reporting any child-based outcome in which any variant of Triple P was evaluated in relation to a comparison condition. Unpublished data, papers in languages other than English and some book chapters were not examined. Studies reporting Eyberg Child Behavior Inventory or Child Behavior Checklist scores as outcomes were used in the meta-analysis. Results A total of 33 eligible studies was identified, most involving media-recruited families. Thirty-one of these 33 studies compared Triple P interventions with waiting list or no-treatment comparison groups. Most papers only reported maternal assessments of child behavior. Twenty-three papers were incorporated in the meta-analysis. No studies involved children younger than two-years old and comparisons of intervention and control groups beyond the duration of the intervention were only possible in five studies. For maternally-reported outcomes the summary effect size was 0.61 (95%CI 0.42, 0.79. Paternally-reported outcomes following Triple P intervention were smaller and did not differ significantly from the control condition (effect size 0.42 (95%CI -0.02, 0.87. The two studies involving an active control group showed no between-group differences. There was limited evidence of publication bias, but there was substantial selective reporting bias, and preferential reporting of positive results in article abstracts. Thirty-two of the 33 eligible studies were authored by Triple-P affiliated personnel. No trials were registered and only two papers contained conflict of interest

    The purpose of this study was to evaluate, through a systematic review, assessment instruments for evidence-based practice (EBP). The specific objectives were to (1) identify survey instruments testing EBP knowledge, skills, attitudes and behaviour; (2) determine the attributes measured by each instrument; (3) evaluate the psychometric properties of the instruments; and (4) evaluate the methodological quality of the instruments. Using the Cochrane approach, searches were conducted in Pubmed, EBSCOHost and Scopus from inception to February 2014. Papers were screened by two independent assessors, and data were extracted by one researcher. Forty papers reporting 34 instruments met the inclusion criteria and were included in the qualitative synthesis. Most instruments measured EBP behaviour (n = 33) and attitudes (n = 21). This review provides a single source of information to enable researchers to select the most robust descriptive instruments to measure EBP learner attributes. Instruments used only with occupational therapists may have resulted in some instruments being missed. For further research, it is recommended that attention is given to developing objective instruments with a focus on knowledge and skills. Copyright © 2015 John Wiley & Sons, Ltd. PMID:26148335

    Background In 2009, the Program in Evidence-based Care (pebc) of Cancer Care Ontario published a guideline on the follow-up of cervical cancer. In 2014, the pebc undertook an update of the systematic review and clinical practice guideline for women in this target population. Methods The literature from 2007 to August 2014 was searched using medline and embase [extended to 2000 for studies of human papillomavirus (hpv) dna testing]. Outcomes of interest were measures of survival, diagnostic accuracy, and quality of life. A working group evaluated the need for changes to the earlier guidelines and incorporated comments and feedback from internal and external reviewers. Results One systematic review and six individual studies were included. The working group concluded that the new evidence did not warrant changes to the 2009 recommendations, although hpv dna testing was added as a potentially more sensitive method of detecting recurrence in patients treated with radiotherapy. Comments from internal and external reviewers were incorporated. Recommendations Summary Follow-up care after primary treatment should be conducted and coordinated by a physician experienced in the surveillance of cancer patients. A reasonable follow-up strategy involves visits every 3–4 months within the first 2 years, and every 6–12 months during years 3–5. Visits should include a patient history and complete physical examination, with elicitation of relevant symptoms. Vaginal vault cytology examination should not be performed more frequently than annually. Combined positron-emission tomography and computed tomography, other imaging, and biomarker evaluation are not advocated; hpv dna testing could be useful as a method of detection of recurrence after radiotherapy. General recommendations for follow-up after 5 years are also provided. PMID:27122975

    Full Text Available Andrew ThomsonCore Medical Publishing, Knutsford, UKIntroduction: Benign prostatic hyperplasia (BPH is a common condition affecting older men. Bothersome symptoms can progress to serious complications such as acute urinary retention (AUR requiring surgical intervention. Dutasteride, a dual 5-alfa-reductase (5AR inhibitor (5ARI, is a recently introduced therapy for the treatment of BPH. Aims: The objective of this article is to review the evidence for the treatment of BPH with dutasteride. Evidence review: Evidence from large clinical studies shows that men with an enlarged prostate achieve a measurable decrease in prostate volume by up to 26% after 4 years of treatment with dutasteride and urinary symptoms improve after 6 months of treatment. This is achieved by rapid suppression (through inhibition of 5AR of the principal androgen (dihydrotestosterone or DHT responsible for stimulating prostatic growth. Evidence suggests that dutasteride treatment results in a reduction in risk (rather than delay of the most serious complications including episodes of AUR and the need for BPH-related surgery. Early symptom relief has been achieved with the combination of an alfa blocker and dutasteride. There is good evidence that dutasteride is well tolerated; side effects limited to sexual dysfunction (reduced libido, impotence, and gynecomastia are more common compared with placebo but occur with a similar incidence to finasteride, another 5ARI. No pharmacoeconomic evidence from studies with dutasteride has so far been published.Clinical value: In conclusion, dutasteride is a valuable treatment option in men with moderate to severe BPH. Reductions in prostate volume lead to symptom relief and serious complications appear to be reduced.Key words: dutasteride, evidence-based review, benign prostatic hyperplasia (BPH, 5-alfa-reductase inhibitor

    2007-01-01

    Objective: This paper provides an overview of the state of evidence-based practice (EBP) in nursing and selected allied health professions and a synopsis of current trends in incorporating EBP into clinical education and practice in these fields. This overview is intended to better equip librarians with a general understanding of the fields and relevant information resources. Included Professions: Professions are athletic training, audiology, health education and promotion, nursing, occupational therapy, physical therapy, physician assisting, respiratory care, and speech-language pathology. Approach: Each section provides a description of a profession, highlighting changes that increase the importance of clinicians' access to and use of the profession's knowledgebase, and a review of each profession's efforts to support EBP. The paper concludes with a discussion of the librarian's role in providing EBP support to the profession. Conclusions: EBP is in varying stages of growth among these fields. The evolution of EBP is evidenced by developments in preservice training, growth of the literature and resources, and increased research funding. Obstacles to EBP include competing job tasks, the need for additional training, and prevalent attitudes and behaviors toward research among practitioners. Librarians' skills in searching, organizing, and evaluating information can contribute to furthering the development of EBP in a given profession. PMID:17971887

    Full Text Available To identify methods of improving the evidence base in smaller surgical specialties, using a systematic review of gastroschisis management as an example.Operative primary fascial closure (OPFC, and silo placement with staged reduction and delayed closure (SR are the most commonly used methods of gastroschisis closure. Relative merits of each are unclear.A systematic review and meta-analysis was performed comparing outcomes following OPFC and SR in infants with simple gastroschisis. Primary outcomes of interest were mortality, length of hospitalization and time to full enteral feeding.751 unique articles were identified. Eight met the inclusion criteria. None were randomized controlled trials. 488 infants underwent OPFC and 316 underwent SR. Multiple studies were excluded because they included heterogeneous populations and mixed intervention groups. Length of stay was significantly longer in the SR group (mean difference 8.97 days, 95% CI 2.14-15.80 days, as was number of post-operative days to complete enteral feeding (mean difference 7.19 days, 95%CI 2.01-12.36 days. Mortality was not statistically significantly different, although the odds of death were raised in the SR group (OR 1.96, 95%CI 0.71-5.35.Despite showing some benefit of OPFC over SR, our results are tempered by the low quality of the available studies, which were small and variably reported. Coordinating research through a National Paediatric Surgical Trials Unit could alleviate many of these problems. A similar national approach could be used in other smaller surgical specialties.

    Background Librarians often teach evidence-based practice (EBP) within health sciences curricula. It is not known what teaching methods are most effective. Methods A systematic review of the literature was conducted searching CINAHL, EMBASE, ERIC, LISTA, PubMed, Scopus, and others. Searches were completed through December 2014. No limits were applied. Hand searching of Medical Library Association annual meeting abstracts from 2009–2014 was also completed. Studies must be about EBP instruction by a librarian within undergraduate or graduate health sciences curricula and include skills assessment. Studies with no assessment, letters and comments, and veterinary education studies were excluded. Data extraction and critical appraisal were performed to determine the risk of bias of each study. Results Twenty-seven studies were included for analysis. Studies occurred in the United States (20), Canada (3), the United Kingdom (1), and Italy (1), with 22 in medicine and 5 in allied health. Teaching methods included lecture (20), small group or one-on-one instruction (16), computer lab practice (15), and online learning (6). Assessments were quizzes or tests, pretests and posttests, peer-review, search strategy evaluations, clinical scenario assignments, or a hybrid. Due to large variability across studies, meta-analysis was not conducted. Discussion Findings were weakly significant for positive change in search performance for most studies. Only one study compared teaching methods, and no one teaching method proved more effective. Future studies could conduct multisite interventions using randomized or quasi-randomized controlled trial study design and standardized assessment tools to measure outcomes. PMID:27366120

    The primary payload for Space Shuttle Mission STS-35, launched December 2, 1990, was the ASTRO-1 Observatory. Designed for round the clock observation of the celestial sphere in ultraviolet and X-ray astronomy, ASTRO-1 featured a collection of four telescopes: the Hopkins Ultraviolet Telescope (HUT); the Wisconsin Ultraviolet Photo- Polarimeter Experiment (WUPPE); the Ultraviolet Imaging Telescope (UIT); and the Broad Band X-ray Telescope (BBXRT). Ultraviolet telescopes mounted on Spacelab elements in cargo bay were to be operated in shifts by flight crew. Loss of both data display units (used for pointing telescopes and operating experiments) during mission impacted crew-aiming procedures and forced ground teams at Marshall Space Flight Center to aim ultraviolet telescopes with fine-tuning by flight crew. BBXRT, also mounted in cargo bay, was directed from outset by ground-based operators at Goddard Space Flight Center. This is the logo or emblem that was designed to represent the ASTRO-1 payload.

    Full Text Available Early enteral nutrition (EN after major digestive surgery has been receiving increasing attention. Supporting evidence has not been clear. This evidence-based review traces the development of early EN and analyses whether it is indeed an advance. We performed a PubMed search in October 2009 with the key words enteral nutrition, early feeding, and gastrointestinal surgery. Our emphasis was on earliest studies documenting the benefits or adverse effects of EN, comparative studies, documenting the benefits or adverse effects of EN, comparative studies, and randomized controlled trials. Thirty-one results were returned from which 17 were included for evaluation (1979-2009. Fifteen papers concluded that early EN was beneficial. In general, patients put on early EN and immunonutrition postoperatively seemed to have decreased hospital stay, decreased complication rates, decreased treatment and hospital costs, and even decreased morbidity and mortality; however, judicious use has been suggested. One study did not recommend early enteral feeding in well-nourished patients at low risk of nutrition-related complications and another suggested that immunonutrition is not beneficial and should not be used routinely. Early EN has been safely given after major digestive surgery since 1979. It benefits patients undergoing major gastrointestinal (GI surgeries, with reduction in perioperative infection, better maintainance of nitrogen balance, and shorter hospital stay. Early EN may be superior to total parenteral nutrition (TPN. However, TPN is perhaps better tolerated in the immediate postoperative period. Early enteral immunonutrition should be used only in malnourished and in transfused patients. Early EN after major digestive surgery is an old advance that is now in fashion.

    Full Text Available The objective was to identify evidence to support use of specific harms for the development of a children and young people’s safety thermometer (CYPST. We searched PubMed, Web of Knowledge, and Cochrane Library post-1999 for studies in pediatric settings about pain, skin integrity, extravasation injury, and use of pediatric early warning scores (PEWS. Following screening, nine relevant articles were included. Convergent synthesis methods were used drawing on thematic analysis to combine findings from studies using a range of methods (qualitative, quantitative, and mixed methods. A review of PEWS was identified so other studies on this issue were excluded. No relevant studies about extravasation injury were identified. The synthesized results therefore focused on pain and skin integrity. Measurement and perception of pain were complex and not always carried out according to best practice. Skin abrasions were common and mostly associated with device related injuries. The findings demonstrate a need for further work on perceptions of pain and effective communication of concerns about pain between parents and nursing staff. Strategies for reducing device-related injuries warrant further research focusing on prevention. Together with the review of PEWS, these synthesized findings support the inclusion of pain, skin integrity, and PEWS in the CYPST.

    AstroArts is the international, online cultural platform of Astronomers Without Borders (AWB). Cofounded in 2012 by visual artist Daniela de Paulis (IT/NL) and astronomer Thilina Heenatigala (Sri Lanka), AstroArts features creative works inspired by astronomy . AstroArts is an international initiative - lead by professionals working in different fields - and includes the 'guest artist of the month' and the Global Astronomy Month programmes. For the 'guest of the month', we feature one artist through a series of weekly blog posts and a Google Hangout on the last week of each month. The Hangout usually includes guests from several of the AWB ongoing programmes, together with the artist, in order to foster collaboration and interdisciplinary discussion. The 'guest of the month' programme is currently expanding to include a virtual residency initiative, which will allow one artist at the time to develop a project in collaboration with scientists affiliated with the AWB network. The projects developed as part of the virtual residency will foster global participation, making the most of online resources. Global Astronomy Month (GAM) is the most popular project of Astronomers Without Borders: founded in 2009 as a follow up of the International Year of Astronomy, GAM is a global platform for astronomy related events that take place every year in April. During GAM, AstroArts is widely featured through online panel discussions with artists and scientists, live film screenings and live performances, often especially designed for web streaming.

    2008-02-01

    Full Text Available Although the prone positioning of a critically ill patient poses a challenge to nursing interventions, it remains the responsibility of nurses to develop a way to provide the same basic and intensive care to those patients lying prone as to those lying supine. The purpose of this study was firstly to conduct a systematic review of the literature as exploration and description of the evidence in support of the beneficial nursing interventions during prone positioning of ventilated patients, and secondly to develop evidence-based nursing guidelines for the nursing process. This exploratory, descriptive and retrospective systematic review includes data from 45 clinical trials, with a total population of 2 148 patients. Data was extracted onto data abstraction forms, assessed for methodological quality and finally summarised in evidence tables. All statistical calculations for the meta-analysis were performed by the RevMan 4.2.8 program. Prone positioning showed significant (p < 0.0001 increases in the partial pressure of oxygen in arterial blood (PaO2 weighted mean difference (WMD = 11.43 and the partial pressure of oxygen in arterial blood/fraction of inspired oxygen (PaO2/FiO2 ratio (WMD = 21.58, 95% CI = 11.36; 31.8. The effects of complications, oxygenation and haemodynamic outcomes compared with the different prone-positioning protocols produced inconclusive results. Nursing guidelines for prone positioning were developed based on the best available evidence. The lack of related articles on nursing care of prone positioning was a drawback. Based on these results, recommendations are made towards further study on the nursing care of prone-positioned patients. Opsomming Hoewel maaglêposisionering van die pasiënt, wat in ‘n kritieke toestand is, ‘n uitdaging aan verpleegsorg bied, is dit steeds die verantwoordelikheid van die verpleegkundige om dieselfde basiese en kritieke sorg aan pasiënte te lewer in die maaglêposisie as aan pasi

  11. Developing the Evidence Base to Inform Best Practice: A Scoping Study of Breast and Cervical Cancer Reviews in Low- and Middle-Income Countries.

    Directory of Open Access Journals (Sweden)

    Margaret M Demment

    Full Text Available Breast and cervical cancers have emerged as major global health challenges and disproportionately lead to excess morbidity and mortality in low- and middle-income countries (LMICs when compared to high-income countries. The objective of this paper was to highlight key findings, recommendations, and gaps in research and practice identified through a scoping study of recent reviews in breast and cervical cancer in LMICs.We conducted a scoping study based on the six-stage framework of Arskey and O'Malley. We searched PubMed, Cochrane Reviews, and CINAHL with the following inclusion criteria: 1 published between 2005-February 2015, 2 focused on breast or cervical cancer 3 focused on LMIC, 4 review article, and 5 published in English.Through our systematic search, 63 out of the 94 identified cervical cancer reviews met our selection criteria and 36 of the 54 in breast cancer. Cervical cancer reviews were more likely to focus upon prevention and screening, while breast cancer reviews were more likely to focus upon treatment and survivorship. Few of the breast cancer reviews referenced research and data from LMICs themselves; cervical cancer reviews were more likely to do so. Most reviews did not include elements of the PRISMA checklist.Overall, a limited evidence base supports breast and cervical cancer control in LMICs. Further breast and cervical cancer prevention and control studies are necessary in LMICs.

    Ataxia-telangiectasia (AT) is an autosomal recessive neurodegenerative disorder with immunodeficiency and an increased risk of developing cancer, caused by mutations in the ataxia-telangiectasia mutated (ATM) gene. Logically, blood relatives may also carry a pathogenic ATM mutation. Female carriers of such a mutation have an increased risk of breast cancer. Other health risks for carriers are suspected but have never been studied systematically. Consequently, evidence-based guidelines for carriers are not available yet. We systematically analyzed all literature and found that ATM mutation carriers have a reduced life expectancy because of mortality from cancer and ischemic heart diseases (RR 1.7, 95% CI 1.2-2.4) and an increased risk of developing cancer (RR 1.5, 95% CI 0.9-2.4), in particular breast cancer (RRwomen 3.0, 95% CI 2.1-4.5), and cancers of the digestive tract. Associations between ATM heterozygosity and other health risks have been suggested, but clear evidence is lacking. Based on these results, we propose that all female carriers of 40-50 years of age and female ATM c.7271T>G mutation carriers from 25 years of age onwards be offered intensified surveillance programs for breast cancer. Furthermore, all carriers should be made aware of lifestyle factors that contribute to the development of cardiovascular diseases and diabetes. PMID:26662178

  15. Calibration of the ASTRO-E XRS detector

    International Nuclear Information System (INIS)

    The US-Japanese ASTRO-E observatory, is scheduled to be launched in early 2000. ASTRO-E carries four X-ray CCD detectors and a hard X-ray detector. The CCDs are located at the focus of grazing incidence X-ray mirrors and will primarily provide imaging over 0.4-12 keV bandpass. ASTRO-E also carries the XRS microcalorimeter X-ray detector. A platinum X-ray mirror will focus X-rays onto a 32-element array of microcalorimeter pixels for high-throughput, high-resolution spectroscopy with limited spatial resolution. The mean measured energy resolution of the XRS flight model detector is about 12 eV at 6 keV for the nominal operating temperature of 65 mK. We present results from our calibration of the XRS flight model detector. We describe the methods used to determine the spectral redistribution of the detector and the overall detection efficiency

    Full Text Available Introduction: Comparative effectiveness and efficacy research for analysis and practice (CEERAP was performed to assess the effects of penicillin-based versus erythromycin-based antibiotic treatments in patients with skin and soft tissue infections (SSTIs including cellulitis, impetigo, and erysipelas. Because SSTIs, especially orofacial cellulitis, are volatile infectious diseases of a life-threatening nature, research on the most efficacious remedies is necessary. Methods: The stringent bibliome yielded three systematic reviews, which were examined for quality of research synthesis protocol and clinical relevance. Results: The sample size of three, rendered the statistical analyses and cumulative meta-analysis problematic. Conclusion: The systematic review outlined here should aid in increasing clinical awareness, improving patient health literacy, and promoting consensus of the best evidence base (BEB to mitigate the threat of sepsis and potential death caused by cellulitis infections.

    2008-01-01

    The Committee on Research of the American Neuropsychiatric Association conducted a review of the noncognitive neuropsychiatric manifestations of frontotemporal dementia. The Committee on Research searched reviews and several online databases for all pertinent publications. Single case reports without pathology were excluded, except for psychosis, where single cases made up much of the literature. The strongest evidence supports an association of frontotemporal dementia with the following behaviors: apathy-abulia; disinhibition-impulsivity; loss of insight and self-referential behavior; decreased emotion and empathy; violation of social and moral norms; changes in dietary or eating behavior; and repetitive behaviors. Frontotemporal dementia is less frequently associated with anxiety and mood disorders, which may be a prodrome or risk factor, and rarely presents with delusions or hallucinations. The results of this review highlight the distinct neuropsychiatric manifestations of frontotemporal dementia and the need to reconsider the current diagnostic criteria for this disorder.

    2010-08-01

    Herbal remedies are clearly a complementary and alternative modality used frequently by patients with hemato-oncological neoplasias during the course of their specific treatment. This review focuses on the potential safety and efficacy of herbs which are either used often or even on a daily basis by patients with hematological malignancies or indicated in the herbal pharmacopeias utilized by various traditional systems of medicine, in order to improve the well-being of patients with these cancers. Traditional medicine worldwide is a source for ongoing laboratory research related to the activity of herbs on cultured cell lines derived from patients with leukemia, lymphoma, and myeloma. Although the number of clinical studies in the field of hemato-oncology is limited, there appears to be potential efficacy in studies of mistletoe (Viscum album), green tea, Indian and Middle-Eastern spices, and some traditional Chinese, American, and European herbs. In addition to the potential efficacy of herbs, safety issues are also reviewed here, particularly, the documented and potential side effects, herb-drug interactions, and matters of quality control. Based on the above issues, the authors suggest enhancing doctor-patient communication regarding herbal use by adopting a patient-centered attitude based on scientific perspective. PMID:20528250

    2013-01-01

    The increasing numbers of patients undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA), combined with the rapidly growing repertoire of surgical techniques and interventions available have put considerable pressure on surgeons and other healthcare professionals to produce excellent results with early functional recovery and short hospital stays. The current economic climate and the restricted healthcare budgets further necessitate brief hospitalization while minimizing costs.Clinical pathways and protocols introduced to achieve these goals include a variety of peri-operative interventions to fulfill patient expectations and achieve the desired outcomes.In this review, we present an evidence-based summary of common interventions available to achieve enhanced recovery, reduce hospital stay, and improve functional outcomes following THA and TKA. It covers pre-operative patient education and nutrition, pre-emptive analgesia, neuromuscular electrical stimulation, pulsed electromagnetic fields, peri-operative rehabilitation, modern wound dressings, standard surgical techniques, minimally invasive surgery, and fast-track arthroplasty units.

  11. Current concepts of percutaneous balloon kyphoplasty for the treatment of osteoporotic vertebral compression fractures: Evidence-based review

    Directory of Open Access Journals (Sweden)

    Ming-Kai Hsieh

    2013-08-01

    Full Text Available Vertebral compression fractures constitute a major health care problem, not only because of their high incidence but also due to both direct and indirect consequences on health-related quality of life and health care expenditures. The mainstay of management for symptomatic vertebral compression fractures is targeted medical therapy, including analgesics, bed rest, external fixation, and rehabilitation. However, anti-inflammatory drugs and certain types of analgesics can be poorly tolerated by elderly patients, and surgical fixation often fails due to the poor quality of osteoporotic bone. Balloon kyphoplasty and vertebroplasty are two minimally invasive percutaneous surgical approaches that have recently been developed for the management of symptomatic vertebral compression fractures. The purpose of this study was to perform a comprehensive review of the literature and conduct a meta-analysis to compare clinical outcomes of pain relief and function, radiographic outcomes of the restoration of anterior vertebral height and kyphotic angles, and subsequent complications associated with these two techniques.

    2014-01-01

    The purpose of this study was to systematically analyze existing literature testing the effectiveness of programs involving the management of suicidal and self-harming behaviors in prisons. For the study, 545 English-language articles published in peer reviewed journals were retrieved using the terms "suicid*," "prevent*," "prison," or "correctional facility" in SCOPUS, MEDLINE, PROQUEST, and Web of Knowledge. In total, 12 articles were relevant, with 6 involving multi-factored suicide prevention programs, and 2 involving peer focused programs. Others included changes to the referral and care of suicidal inmates, staff training, legislation changes, and a suicide prevention program for inmates with Borderline Personality Disorder. Multi-factored suicide prevention programs appear most effective in the prison environment. Using trained inmates to provide social support to suicidal inmates is promising. Staff attitudes toward training programs were generally positive. PMID:24611725

    Full Text Available Emiliano Angeloni Cardiovascular Pathophysiology and Imaging, Sapienza Università di Roma, Rome, Italy Background: Azilsartan (AZI is a relatively new angiotensin receptor blocker available for the treatment of any stage of hypertension, which was eventually given in combination with chlorthalidone (CLT. Objective: To review pharmacology and clinical role of AZI monotherapy and AZI/CLT or AZI/amlodipine combination therapies for hypertension management. Methods: PubMed, Embase, and Cochrane Library were searched using search terms “azilsartan”, “chlorthalidone,” “pharmacology,” “pharmacokinetics,” “pharmacodynamics,” “pharmacoeconomics,” and “cost-effectiveness.” To obtain other relevant information, US Food and Drug Association as well as manufacturer prescribing information were also reviewed. Results: Randomized controlled trials demonstrated AZI to be superior to other sartans, such as valsartan, olmesartan, and candesartan, in terms of 24-hour ambulatory blood pressure monitoring (ABPM reduction with respect. That beneficial effect of azilsartan was also associated with similar safety profiles. When compared to other antihypertensive drugs, azilsartan was found to be superior to any angiotensin-converting enzyme inhibitor, including ramipril, in terms of ABPM results, and noninferior to amlodipine in terms of sleep-BP control. The association of AZI and CLT was then found to be superior to other sartans + thiazide combination therapies in terms of both BP lowering and goal achievement. The combination of AZI and amlodipine has also been tested in clinical trials, but compared only with placebo, demonstrating its superiority in terms of efficacy and similarity in terms of safety. Conclusion: Azilsartan is a safe and effective treatment option for every stage of hypertension, both alone or in fixed-dose combination tablets with chlorthalidone or amlodipine. Beneficial effects of AZI were also noted in patients

    2015-04-01

    Full Text Available David J Hellerstein,1,2 Joseph Flaxer11Department of Psychiatry, Columbia University, 2New York State Psychiatric Institute, New York, NY, USAIntroduction: It has clearly been demonstrated that depressive disorders constitute a major worldwide public health problem, with massive economic and quality-of-life consequences. Existing pharmacological treatments have limited efficacy, with only about a third of patients achieving remission on any one medication. Delayed onset of action and variable tolerability contribute to this limited efficacy. Vilazodone, introduced in the US in 2011, has been described as the first member of the serotonin partial agonist-reuptake inhibitor (SPARI class of medications, combining serotonin-reuptake inhibition with 5-HT1A partial agonism. This agent could potentially have benefits for subgroups of depressed patients, including depressed patients with comorbid anxiety and patients with anxiety disorders, and might have fewer sexual side effects than selective serotonin-reuptake inhibitors (SSRIs.Aims: We reviewed existing clinical trials that assess the benefits of vilazodone for treatment of major depression.Evidence review: In clinical trials, including two Phase III studies and two Phase IV studies, vilazodone has been shown to have efficacy greater than placebo on the Montgomery–Åsberg Depression Rating Scale, comparable efficacy to citalopram, and continued benefit after 52 weeks of treatment. The safety profile for vilazodone is comparable to other SSRI medications, and tolerability also appears generally comparable to other SSRI medications.Place in therapy: Vilazodone, which has been described as the first-of-class SPARI medication, may potentially have benefits for subgroups of patients, particularly those depressed individuals with coexisting anxiety symptoms or anxiety disorders. However, convincing evidence for these benefits has as yet not been published.Keywords: vilazodone, antidepressant

    Background Azilsartan (AZI) is a relatively new angiotensin receptor blocker available for the treatment of any stage of hypertension, which was eventually given in combination with chlorthalidone (CLT). Objective To review pharmacology and clinical role of AZI monotherapy and AZI/CLT or AZI/amlodipine combination therapies for hypertension management. Methods PubMed, Embase, and Cochrane Library were searched using search terms “ azilsartan”, “chlorthalidone,” “pharmacology,” “pharmacokinetics,” “pharmacodynamics,” “pharmacoeconomics,” and “cost-effectiveness.” To obtain other relevant information, US Food and Drug Association as well as manufacturer prescribing information were also reviewed. Results Randomized controlled trials demonstrated AZI to be superior to other sartans, such as valsartan, olmesartan, and candesartan, in terms of 24-hour ambulatory blood pressure monitoring (ABPM) reduction with respect. That beneficial effect of azilsartan was also associated with similar safety profiles. When compared to other antihypertensive drugs, azilsartan was found to be superior to any angiotensin-converting enzyme inhibitor, including ramipril, in terms of ABPM results, and noninferior to amlodipine in terms of sleep-BP control. The association of AZI and CLT was then found to be superior to other sartans + thiazide combination therapies in terms of both BP lowering and goal achievement. The combination of AZI and amlodipine has also been tested in clinical trials, but compared only with placebo, demonstrating its superiority in terms of efficacy and similarity in terms of safety. Conclusion Azilsartan is a safe and effective treatment option for every stage of hypertension, both alone or in fixed-dose combination tablets with chlorthalidone or amlodipine. Beneficial effects of AZI were also noted in patients with any degree of renal impairment. In addition, safety profiles of AZI were similar to that of the placebo. PMID:27103882

    Full Text Available Carole NadinCore Medical Publishing, Knutsford, UKIntroduction: Patients on hemodialysis require phosphate binders to reduce dietary phosphate absorption and control serum phosphate. The standard therapy, calcium salts, can be associated with elevated serum calcium (hypercalcemia. Concern has been raised that hypercalcemia, especially combined with elevated serum phosphate, may be associated with arterial calcification, and this may contribute to increased risk of cardiovascular mortality and morbidity. Sevelamer is a nonmetal, nonabsorbed phosphate binder.Aims: This review assesses the evidence for the therapeutic value of sevelamer as a phosphate binder in adult hemodialysis patients.Evidence review: Strong evidence shows that sevelamer is as effective as calcium salts in controlling serum phosphate and calcium–phosphate product, has less risk of inducing hypercalcemia and is more effective at lowering lipid levels. Some evidence indicates that sevelamer reduces arterial calcification progression and loss of bone mineral density, but it may be more likely to induce metabolic acidosis, compared with calcium salts. Sevelamer-containing regimens may improve calcific uremic arteriolopathy, although the evidence is weak. Evidence is divided on whether the incidence of gastrointestinal adverse events with sevelamer is similar to or higher than that with calcium salts. Retrospective and modeling studies suggest lower cardiovascular morbidity and mortality with sevelamer than with calcium salts, with incremental cost-effectiveness of $US1100–2200 per life-year gained. Further direct evidence is needed on mortality, quality of life, and cost-effectiveness.Place in therapy: Sevelamer is effective in controlling serum phosphate and lowering lipid levels in hemodialysis patients without inducing hypercalcemia, and may have beneficial effects on arterial calcification.Key words: sevelamer, calcium salts, phosphate binder, hemodialysis, chronic kidney

    This systematic review investigated, critically appraised, and rated the evidence on agents used to prevent oral mucositis in children. A comprehensive search of the relevant literature was performed up to December 2011. Articles were included according to the inclusion/exclusion criteria and were critically appraised for validation and quality assessment using a checklist consisting of 18 categories. Each article was then rated for its strength of evidence. 16,471 articles were retrieved from 19 different databases and then reduced to 27 articles that fit the inclusion criteria. Five articles on oral care protocols supported their use to prevent oral mucositis in children. Seven articles on chlorhexidine mouthwash and three on laser therapy had conflicting evidence of its use. The preventative agents that were supported by one or two articles included: benzydamine mouthwash, iseganan mouthwash, granulocyte-macrophage colony-stimulating factor (GM-CSF) mouthwash, oral/enteral glutamine, oral propantheline and cryotherapy, oral cryotherapy, oral sucralfate suspension, prostaglandin E2 tablets, and chewing gum. The reduction in the rates of occurrence of oral mucositis when using agents of fair (B) to good (A) evidence ranged from 22% to 52%. In conclusion, this review suggests the use of oral care protocols to prevent oral mucositis in children because of their strength of evidence (fair to good). The authors suggest avoiding agents with fair to good evidence against their use (oral sucralfate suspension, prostaglandin E2 tablets, and GM-CSF mouthwash). Agents with conflicting evidence (chlorhexidine mouthwash (used solely), laser therapy, and glutamine) should also be avoided until further research confirms their efficacy. PMID:22959949

    Neuropsychological evaluation is one component of a comprehensive and multifaceted assessment following concussion. Although some neuropsychologists use a "hybrid" assessment approach integrating computerized neurocognitive testing batteries with traditional paper and pencil tests, computerized neurocognitive test batteries are the predominant testing modality for assessment of athletes from the youth to professional level. This review summarizes the most recent research supporting the utility of neuropsychological evaluation and highlights the strengths and weaknesses of both computerized and traditional neuropsychological testing approaches. The most up to date research and guidelines on baseline neurocognitive testing is also discussed. This paper addresses concerns regarding reliability of neuropsychological testing while providing an overview of factors that influence test performance, both transient situational factors (e.g., pain level, anxiety) and characteristics of particular subgroups (e.g., age, preexisting learning disabilities), warranting the expertise of an experienced neuropsychologist for interpretation. Currently, research is moving forward by integrating neuropsychological evaluation with emerging assessment approaches for other domains of brain function (e.g., vestibular function) vulnerable to concussion.

Measures of dynamic lower extremity valgus have been previously shown to relate to increased risk of several knee pathologies, specifically anterior cruciate ligament ruptures and patellofemoral pain. Therefore, hip-focused interventions have gained considerable attention and been successful in addressing these knee pathologies. The purpose of the review was to identify and discuss hip-focused exercise interventions that aim to address dynamic lower extremity valgus. Previous electromyography, kinematics, and kinetics research support the use of targeted hip exercises with non-weight-bearing, controlled weight-bearing, functional exercise, and, to a lesser extent, dynamic exercises in reducing dynamic lower extremity valgus. Further studies should be developed to identify and understand the mechanistic relationship between optimized biomechanics during sports and hip-focused neuromuscular exercise interventions.Keywords: dynamic lower extremity valgus, hip neuromuscular control, ACL injury rehabilitation, patellofemoral pain, hip muscular activation

    In recent years there has been an increase in the popularity of home visitation programs as a means of addressing risk factors for child maltreatment. The evidence supporting the effectiveness of these programs from several meta-analyses, however, is mixed. One potential explanation for this inconsistency explored in the current study involves the manner in which these programs were implemented. In the current study we reviewed 156 studies associated with 9 different home visitation program models targeted to caregivers of children between the ages of 0 and 5. Meta-analytic techniques were used to determine the impact of 18 implementation factors (e.g., staff selection, training, supervision, fidelity monitoring, etc.) and four study characteristics (publication type, target population, study design, comparison group) in predicting program outcomes. Results from analyses revealed that several implementation factors, including training, supervision, and fidelity monitoring, had a significant effect on program outcomes, particularly child maltreatment outcomes. Study characteristics, including the program's target population and the comparison group employed, also had a significant effect on program outcomes. Implications of the study's results for those interested in implementing home visitation programs are discussed. A careful consideration and monitoring of program implementation is advised as a means of achieving optimal study results. PMID:26724823

    Tuberous sclerosis complex (TSC) is a relatively rare genetic disorder, affecting one in 6,000 births. Mammalian target of rapamycin (mTOR) inhibitors, such as everolimus, which have been previously used to prevent solid organ transplant rejection, augment anticancer treatment regimens, and prevent neovascularization of artificial cardiac stents, are now approved for treating TSC-related manifestations, such as subependymal giant cell astrocytomas and renal angiomyolipomas. The use of everolimus in treating subependymal giant cell astrocytomas is supported by long-term Phase II and III clinical trials. Seizures are a common feature in TSC, occurring in up to 96% of patients. While mTOR inhibitors currently do not have regulatory approval in treating this manifestation, small clinical studies have demonstrated beneficial outcomes with everolimus. Further evidence from a forthcoming Phase III clinical study may provide additional support for the use of everolimus for this indication. Also, there are no approved treatments for TSC-associated neuropsychiatric disorders, which include intellectual disability, behavioral difficulties, and autism spectrum disorder, but preclinical data and small studies have suggested that some neuropsychiatric symptoms may be improved through mTOR inhibition therapy. More evidence is needed, particularly regarding safety in young infants. This review focuses on the current evidence supporting the use of everolimus in neurologic and neuropsychiatric manifestations of TSC, and the place of everolimus in therapy. PMID:27601910

    Consumption of 100% fruit juice remains controversial for its potential adverse impact on weight and displacement of essential foods in the diets of children. A systematic review of the literature published from 1995-2013 was conducted using the PubMed database to evaluate associations between intake of 100% fruit juice and weight/adiposity and nutrient intake/adequacy among children of 1 to 18 years of age. Weight status outcome measures included body mass index (BMI), BMI z-score, ponderal index, obesity, weight gain, adiposity measures, and body composition. Nutrient outcome measures included intake and adequacy of shortfall nutrients. Data extraction and analysis was conducted according to the Academy of Nutrition and Dietetics Evidence Analysis Process. Twenty-two studies on weight status provided evidence that did not support an association between 100% fruit juice consumption and weight/adiposity in children after controlling for energy intake. Limited evidence from eight studies suggests that children consuming 100% fruit juice have higher intake and adequacy of dietary fiber, vitamin C, magnesium, and potassium. Differences in methodology and study designs preclude causal determination of 100% fruit juice as sole influencer of weight status or nutrient intake/adequacy of shortfall nutrients. In context of a healthy dietary pattern, evidence suggests that consumption of 100% fruit juice may provide beneficial nutrients without contributing to pediatric obesity. PMID:26091353

    Corticosteroids have been proposed as an adjunct to antibiotics for the treatment of bacterial keratitis, with significant controversy regarding the appropriate use of this therapy. Recent prospective randomised controlled trials have provided additional evidence to guide clinical decision-making. A review of the epidemiology and mechanisms of pathogenesis, preliminary animal studies, retrospective human studies and prospective randomised clinical trials that address the potential risks and benefits of corticosteroids in patients with bacterial keratitis was performed. Four prospective randomised controlled trials were identified. Three small studies found no benefit of topical corticosteroids, but were underpowered to evaluate adverse events. The Steroids for Corneal Ulcers Trial (SCUT) study and subgroup analyses provide evidence for a relative gain of one line of best spectacle-corrected visual acuity in patients with non-Nocardia bacterial keratitis, especially when corticosteroids were initiated within 3 days of presentation; no increase in adverse events was noted. No evidence was found to support the concern for corneal thinning attributable to corticosteroids in the absence of an inadequately treated infectious process. In patients with culture-proven non-Nocardia bacterial keratitis, corticosteroids provide one line of vision improvement over antimicrobials alone, with no increase in adverse events. This benefit should not be extrapolated to patients with other aetiologies of keratitis, such as fungus, herpes viruses, acanthamoeba or atypical mycobacteria, and these entities should be excluded before considering adjunctive steroid therapy.

    Full Text Available Julio C Chavez, Eva Sahakian, Javier Pinilla-IbarzH Lee Moffitt Cancer and Research Institute, Division of Malignant Hematology, and University of South Florida, Tampa, FL, USAAbstract: Chronic lymphocytic leukemia (CLL is a heterogeneous disease with a variable course, and remains an incurable disease. Frequent relapses and eventual resistance to fludarabine characterize symptomatic CLL and portends a dismal prognosis for patients. Growing evidence has shown that signaling pathways such as the B cell receptor and NFkB are implicated in the survival and proliferation of the CLL cells which are ultimately associated with persistence of the disease. The Bruton’s tyrosine kinase pathway regulates downstream activation of the B cell receptor and has emerged as an attractive target. Ibrutinib inhibits the Bruton’s tyrosine kinase pathway, and consequently induces apoptosis of B cells. Phase I and II studies have shown impressive response rates with an excellent safety profile in patients with refractory/relapsed CLL and elderly treatment-naïve CLL patients. This paper reviews the preclinical and clinical data for ibrutinib when used in the treatment of CLL. Recent studies showing the benefit of combination therapy using ibrutinib, monoclonal antibodies, and chemoimmunotherapy are also discussed.Keywords: ibrutinib, B-cell receptor, chronic lymphocytic leukemia, Bruton’s tyrosine kinase

The prevention and treatment of VTE is managed with anticoagulant therapy, historically parenteral anticoagulants such as unfractionated heparin, low molecular weight heparin, and fondaparinux, and oral vitamin K antagonists such as warfarin. In the last few years, several target-specific oral anticoagulants have been developed, including the direct thrombin inhibitor dabigatran and anti-Xa inhibitors rivaroxaban, apixaban, and edoxaban. The target-specific oral anticoagulants have proven to be noninferior to vitamin K antagonists and heparins in the prevention and treatment of VTE. This review will focus on the pharmacology, clinical trial data, and laboratory assessment of apixaban. Moreover, perioperative management, use in special populations, and management of bleeding complications in patients taking apixaban for the prevention and treatment of VTE will also be discussed.

    Infants in the neonatal intensive care unit are highly susceptible to healthcare associated infections (HAI), with a substantial impact on mortality, morbidity and healthcare costs. Effective skin disinfection with topical antiseptic agents is an important intervention in the prevention or reduction of HAI. A wide array of antiseptic preparations in varying concentrations and combinations has been used in neonatal units worldwide. In this article we have reviewed the current evidence of a preferred antiseptic of choice over other agents for topical skin disinfection in neonates. Chlorhexidine (CHG) appears to be a promising antiseptic agent; however there exists a significant concern regarding the safety of all agents used including CHG especially in preterm and very low birth weight infants. There is substantial evidence to support the use of CHG for umbilical cord cleansing and some evidence to support the use of topical emollients in reducing the mortality in infants born in developing countries. Well-designed large multicentre randomized clinical trials are urgently needed to guide us on the most appropriate and safe antiseptic to use in neonates undergoing intensive care, especially preterm infants.

    Full Text Available Abstract Background Demographic projections suggest a major increase in non-communicable disease (NCD mortality over the next two decades in developing countries. In a climate of scarce resources, policy-makers need to know which interventions represent value for money. The prohibitive cost of performing multiple economic evaluations has generated interest in transferring the results of studies from one setting to another. This paper aims to bridge the gap in the current literature by critically evaluating the available published data on economic evaluations of NCD interventions in developing countries. Methods We identified and reviewed the methodological quality of 32 economic evaluations of NCD interventions in developing countries. Developing countries were defined according to the World Bank classification for low- and lower middle-income countries. We defined NCDs as the 12 categories listed in the 1993 World Bank report Investing in Health. English language literature was searched for the period January 1984 and January 2003 inclusive in Medline, Science Citation Index, HealthStar, NHS Economic Evaluation Database and Embase using medical subheading terms and free text searches. We then assessed the quality of studies according to a set of pre-defined technical criteria. Results We found that the quality of studies was poor and resource allocation decisions made by local and global policy-makers on the basis of this evidence could be misleading. Furthermore we have identified some clear gaps in the literature, particularly around injuries and strategies for tackling the consequences of the emerging tobacco epidemic. Conclusion In the face of poor evidence the role of so-called generalised cost-effectiveness analyses has an important role to play in aiding public health decision-making at the global level. Further research is needed to investigates the causes of variation among cost, effects and cost-effectiveness data within and between

    Wound healing after dermal injury is an imperfect process, inevitably leading to scar formation as the skin re-establishes its integrity. The resulting scars have different characteristics to normal skin, ranging from fine-line asymptomatic scars to problematic scarring including hypertrophic and keloid scars. Scars appear as a different colour to the surrounding skin and can be flat, stretched, depressed or raised, manifesting a range of symptoms including inflammation, erythema, dryness and pruritus, which can result in significant psychosocial impact on patients and their quality of life. In this paper, a comprehensive literature review coupled with an analysis of levels of evidence (LOE) for each published treatment type was conducted. Topical treatments identified include imiquimod, mitomycin C and plant extracts such as onion extract, green tea, Aloe vera, vitamin E and D, applied to healing wounds, mature scar tissue or fibrotic scars following revision surgery, or in combination with other more established treatments such as steroid injections and silicone. In total, 39 articles were included, involving 1703 patients. There was limited clinical evidence to support their efficacy; the majority of articles (n = 23) were ranked as category 4 LOE, being of limited quality with individual flaws, including low patient numbers, poor randomisation, blinding, and short follow-up periods. As trials were performed in different settings, they were difficult to compare. In conclusion, there is an unmet clinical need for effective solutions to skin scarring, more robust long-term randomised trials and a consensus on a standardised treatment regime to address all aspects of scarring.

Bortezomib, the first proteasome inhibitor approved for MM therapy, has been shown to increase response rate and improve outcome in patients with relapsed/refractory disease and in the frontline setting, particularly when combined with immunomodulatory drugs and alkylating agents. Among second-generation proteasome inhibitors, ixazomib (MLN9708 is the first oral compound to be evaluated for the treatment of MM. Ixazomib has shown improved pharmacokinetic and pharmacodynamic parameters compared with bortezomib, in addition to similar efficacy in the control of myeloma growth and prevention of bone loss. Ixazomib was found to overcome bortezomib resistance and to trigger synergistic antimyeloma activity with dexamethasone, lenalidomide, and histone deacetylase inhibitors. Phase I/II studies using ixazomib weekly or twice weekly in relapsed/refractory MM patients suggested antitumor activity of the single agent, but more promising results have been obtained with the combination of ixazomib, lenalidomide, and dexamethasone in newly diagnosed MM. Ixazomib has also been used in systemic amyloidosis as a single agent, showing important activity in this difficult-to-treat plasma-cell dyscrasia. More frequent side effects observed during administration of ixazomib were thrombocytopenia, nausea, vomiting, diarrhea, fatigue, and rash, whereas severe peripheral neuropathy was rare.

    Female sex hormones play an important role in the etiology and pathophysiology of a variety of musculoskeletal degenerative diseases. Postmenopausal women show accelerated disc degeneration due to relative estrogen deficiency. This literature review aims to validate or falsify this hypothesis, i.e., while overall females have higher prevalence of low back pain (LBP) across all age groups, this male vs. female difference in LBP prevalence further increases after female menopause age. The literature search was performed on PubMed on January 2, 2016. The search word combination was (low back pain) AND prevalence AND [(males OR men) AND (females OR women)]. The following criteria were taken to include the papers for synthetic analysis: (I) only English primary literatures on nonspecific pain; (II) only prospective studies on general population, but not population with occupational LBP causes, of both males and female subjects studied using the same LBP criterion, ages-specific information available, and males and female subjects were age-matched; (III) studies without major quality flaws. In total 98 studies with 772,927 subjects were analyzed. According to the information in the literature, participant subjects were divided into four age groups: (I) school age children group: 6–19 years; (II) young and middle aged group: 20–50 years; (III) mixed age group: data from studies did not differentiate age groups; (IV) elderly group: ≥50 years old. When individual studies were not weighted by participant number and each individual study is represented as one entry regardless of their sample size, the median LBP prevalence ratio of female vs. males was 1.310, 1.140, 1.220, and 1.270 respectively for the four age groups. When individual studies were weighted by participant number, the LBP prevalence ratio of female vs. males was 1.360, 1.127, 1.185, and 1.280 respectively for the four groups. The higher LBP prevalence in school age girls than in school age boys is likely

    The joint JAXA/NASA ASTRO-H mission is the sixth in a series of highly successful X-ray missions initiated by the Institute of Space and Astronautical Science (ISAS). ASTRO-H will investigate the physics of the high-energy universe by performing high-resolution, high-throughput spectroscopy with moderate angular resolution. ASTRO-H covers very wide energy range from 0.3 keV to 600 keV. ASTRO-H allows a combination of wide band X-ray spectroscopy (5-80 keV) provided by multilayer coating, focusing hard X-ray mirrors and hard X-ray imaging detectors, and high energy-resolution soft X-ray spectroscopy (0.3-12 keV) provided by thin-foil X-ray optics and a micro-calorimeter array. The mission will also carry an X-ray CCD camera as a focal plane detector for a soft X-ray telescope (0.4-12 keV) and a non-focusing soft gamma-ray detector (40-600 keV) . The micro-calorimeter system is developed by an international collaboration led by ISAS/JAXA and NASA. The simultaneous broad bandpass, coupled with high spectral reso...

    2013-08-01

    Full Text Available A dramatic rise in arrest rates for girls over the past decade has led to an increasing interest in understanding gender differences in the risk factors that are associated with delinquency. Moreover, the call has been made for the implementation of gender-specific or gender-responsive interventions in order to effectively divert girls from an antisocial course. However, questions have been raised about three key assumptions underlying the gender-responsive approach to girls involved in the juvenile justice system: is there unequivocal evidence for gender-specificity in the risk factors that contribute to girls’ delinquency; is there clear evidence that existing non-gender-responsive evidence-based interventions for delinquency are less effective for girls than boys; and is there well-grounded evidence that interventions specifically tailored for girls are differentially effective? This article reviews the available research regarding each of these questions and proposes an agenda for future research into the development of effective interventions for juvenile justice-involved girls.

    Full Text Available Abstract Background A major marketing technique used by pharmaceutical companies is direct-to-physician marketing. This form of marketing frequently employs promotional marketing brochures, based on clinical research, which may influence how a physician prescribes medicines. This study's objective was to investigate whether or not the information in promotional brochures presented to physicians by pharmaceutical representatives is accurate, consistent, and valid with respect to the actual studies upon which the promotional brochures are based. Methods Physicians in five clinics were asked to consecutively collect pharmaceutical promotional brochures and to send them all to a centralized location. The brochures for any class of medication were collected on a continuous basis until 20 distinct promotional brochures were received by a central location. Once the brochure was received, the corresponding original study was obtained. Two blinded reviewers performed an evidence-based review of the article, comparing data that was printed on the brochure to what was found in the original study. Results Among the 20 studies, 75% of the studies were found to be valid, 80% were funded by the pharmaceutical company, 60% of the studies and the corresponding brochures presented patient-oriented outcomes, and 40% were compared to another treatment regimen. Of the 19 brochures that presented the data as graphs, 4 brochures presented a relative risk reduction while only 1 brochure presented an absolute risk reduction. 15% of the promotional marketing brochures presented data that was different from what was in the original published study. Conclusion Given the present findings, physicians should be cautious about drawing conclusions regarding a medication based on the marketing brochures provided by pharmaceutical companies.

  17. An evidence-based environmental perspective of manufactured silver nanoparticle in syntheses and applications: A systematic review and critical appraisal of peer-reviewed scientific papers

    International Nuclear Information System (INIS)

    Background: Most recently, renewed interest has arisen in manufactured silver nanomaterials because of their unusually enhanced physicochemical properties and biological activities compared to the bulk parent materials. A wide range of applications has emerged in consumer products ranging from disinfecting medical devices and home appliances to water treatment. Because the hypothesized mechanisms that govern the fate and transport of bulk materials may not directly apply to materials at the nanoscale, there are great concerns in the regulatory and research communities about potential environmental impacts associated with the use of silver nanoparticles. In particular, the unlimited combinations of properties emerging from the syntheses and applications of silver nanoparticles are presenting an urgent need to document the predominant salt precursors, reducing agents and stabilizing agents utilized in the synthesis processes of silver nanoparticles to guide the massive efforts required for environmental risk assessment and management. Objectives: The primary objective of this study is to present an evidence-based environmental perspective of silver nanoparticle properties in syntheses and applications. The following specific aims are designed to achieve the study objective: Aim 1 - to document the salt precursors and agents utilized in synthesizing silver nanoparticles; Aim 2 - to determine the characteristics of silver nanoparticles currently in use in the scientific literature when integrated in polymer matrices to form nanocomposites and combined with other metal nanoparticles to form bimetallic nanoparticles; Aim 3 - to provide a summary of the morphology of silver nanoparticles; and (4) Aim 4 - to provide an environmental perspective of the evidence presented in Aims 1 to 3. Methods: A comprehensive electronic search of scientific databases was conducted in support of the study objectives. Specific inclusion criteria were applied to gather the most pertinent

    Full Text Available The importance of evidence for every branch of medicine in teaching in order to orient the practitioners among the great amount of most actual scientific information's, and to support clinical decisions, is well established in health care, including dentistry. The practice of evidence-based medicine is a process of lifelong, self-directed, problem-based learning which leads to the need for clinically important information about diagnosis, prognosis, therapy and other clinical and health care issues. Nowadays the practice of dentistry is becoming more complex and challenging because of the continually changing in dental materials and equipments, an increasingly litigious society, an increase in the emphasis of continuing professional development, the information explosion and the consumer movement associated with advances on the Internet. The need for reliable information and the electronic revolution have come together to allow the “paradigm shift” towards evidence-based health care. Recent years have seen an increase in the importance of evidence-based dentistry, aiming to reduce to the maximum the gap between clinical research and real world dental practice. Aim of evidence-based practice is the systematic literature review, which synthesizes the best evidences and provides the basis for clinical practice guidelines. These practice guidelines give a brief review of what evidence-based dentistry is and how to use it.

    Chambers, David W

    2010-01-01

    Both panegyric and criticism of evidence-based dentistry tend to be clumsy because the concept is poorly defined. This analysis identifies several contributions to the profession that have been made under the EBD banner. Although the concept of clinicians integrating clinical epidemiology, the wisdom of their practices, and patients' values is powerful, its implementation has been distorted by a too heavy emphasis of computerized searches for research findings that meet the standards of academics. Although EBD advocates enjoy sharing anecdotal accounts of mistakes others have made, faulting others is not proof that one's own position is correct. There is no systematic, high-quality evidence that EBD is effective. The metaphor of a three-legged stool (evidence, experience, values, and integration) is used as an organizing principle. "Best evidence" has become a preoccupation among EBD enthusiasts. That overlong but thinly developed leg of the stool is critiqued from the perspectives of the criteria for evidence, the difference between internal and external validity, the relationship between evidence and decision making, the ambiguous meaning of "best," and the role of reasonable doubt. The strongest leg of the stool is clinical experience. Although bias exists in all observations (including searches for evidence), there are simple procedures that can be employed in practice to increase useful and objective evidence there, and there are dangers in delegating policy regarding allowable treatments to external groups. Patient and practitioner values are the shortest leg of the stool. As they are so little recognized, their integration in EBD is problematic and ethical tensions exist where paternalism privileges science over patient's self-determined best interests. Four potential approaches to integration are suggested, recognizing that there is virtually no literature on how the "seat" of the three-legged stool works or should work. It is likely that most dentists

    Traumatic brain injury (TBI) is defined as an alteration in brain function caused by an external force. Mild TBI or concussion is now well recognized to be a risk of military service as well as participation in athletic sports such as football. Posttraumatic headache (PTH) is the most common symptom after mTBI in US service members. PTH most commonly presents with migraine-like headache features. The following is an overview of the epidemiology, pathophysiology, clinical course, prognosis, complications, and treatment of mTBI and associated comorbidities with a focus on PTH. There is a particular emphasis on emerging evidence-based clinical practice. One important medical consequence of the recognition that mTBI is a highly prevalent among military service members is that the Department of Defense (DoD) is dedicating significant financial and intellectual resources to better understanding and developing treatments for TBI. The identification of the importance of TBI among the US military population has had the added benefit of increasing awareness of this condition among civilian populations, particularly those engaged in both professional and youth sports. The NIH and NSF are also supporting important TBI research. President Obama's Brain Initiative is also providing additional impetus for these efforts. Unfortunately, the understanding of the acute and chronic effects of mTBI on the brain remains limited. Gratefully, there is hope that through innovative research, there will be advances in elucidating the underlying pathophysiology, which will lead to clinical and prognostic indicators, ultimately resulting in new treatment options for this very complicated set of disorders.

    2005-01-01

    Purpose: The evidence-based medicine (EBM) is a new medical mode that is completely different from traditional experience-based medicine. The core of EBM is that decision-making during clinical practices must be based on objective research results.With the rapid development of modern ophthalmology, some former viewpoints according to experience-based medicine face challenges. Evidence-based ophthalmology (EBO) is imperative under the situation. Glaucoma, as a disease resulting in blindness, which can not be cured by operation, is thought more and more of by medical management officials and doctors. One challenge for ophthalmologists entering the 21st century will be to make clinical decisions based on valid information or evidence rather than intuition, hearsay, or peer practice. How can we do? Here reviews the application of EBM in medical management of glaucoma since EBM' s naissance and give a reference.

    Dental problems are some of the most common reasons for a horse to be presented to an equine veterinarian. Despite the importance of anecdotal evidence as a starting point, the science of equine dentistry (especially prophylactic dentistry) has remained poorly supported by evidence-based approaches to diagnosis and treatment. In the 21st century, veterinarians have an ethical responsibility to promote and use the results of evidence-based research and not propagate statements attesting to the purported benefits of intervention without supporting research. Consider also that society is becoming more litigious and therefore is basing treatment plans and advice on published research, which protects the profession from legal challenges concerning our professional conduct. This article reviews the current published evidence concerning the role of equine dentistry in feed digestibility and performance. PMID:17616326

    Full Text Available Falls have been a major safety concern in view of its high incidences and potential detrimental consequences. This article described a systematic review about effectiveness of interventions for the assessment and prevention of falls in adult psychiatric patients conducted previously. These patients possessed unique fall-related risk factors such as altered mental status, physiological symptoms, past history of falls, mobility and gait problems, concurrent medical conditions, and polypharmacy that might warrant specific tailored fall prevention interventions. Following the systematic review, a care bundle for fall prevention in a tertiary psychiatric hospital would be implemented, taking into account these risk factors and evidence relating to fall prevention.

    contributing to the existing literature by publishing original research. One of the strengths of the EBLIP journal is the Evidence Summaries section. Not only are these critical appraisals of previously published research, but the critical appraisals themselves are peer reviewed. The knowledge base, therefore, is being populated with original research as well as rigorously evaluated research. Am I still feeling defensive? Perhaps a little. I am sure that the time and effort that I have invested in EBLIP cannot help but create some bias. On the other hand, I have seen that evidence based practice is making an impact on how numerous individuals and institutions approach decision making. I am reading, seeing and hearing about research being designed, performed and evaluated within a new framework. EBP is standard practice in the health professions and is swiftly gaining solid ground in the social sciences, education and in government. Our profession prides itself on being on the cutting edge of information access and management: if information professionals choose not to adopt the model, which has been proven time and time again to be effective, they risk being placed outside cutting edge, innovative practice. Is that where we want to be?

    Infectious diseases remain a major cause of death among young people throughout the world. This paper reviews the current knowledge of empirically validated and promising interventions aimed at preventing infectious diseases among children caused by poor hand hygiene in schools. The study used a standard protocol to identify and review the literature and to classify the selected interventions. Approximately ten interventions were found to have a beneficial effect by promoting hand washing and hand hygiene in schools. The study also found that most of the interventions were implemented at elementary school. However, some interventions were also implemented at kindergarten or in child care centers, while others were aimed at university students. Most of the interventions were implemented by teachers, peers and/or external professionals. The study found that hand hygiene is effective regardless of the type of cleaning product used (i.e. antibacterial or plain soap, alcohol-based or alcohol-free hand sanitizer). This study aims to contribute to the understanding of empirically validated and promising interventions and to promote reflection on professional practice in France. PMID:23782636

    Full Text Available Giuseppe Derosa, Sibilla Anna Teresa SalvadeoDepartment of Internal Medicine and Therapeutics, University of Pavia, Pavia, ItalyIntroduction: Type 2 diabetes mellitus, a metabolic disease with increasing incidence, is one of the most important cardiovascular risk factors. Insulin resistance represents the common mechanism that leads to type 2 diabetes in obese subjects. Metformin and the thiazolidinediones, pioglitazone and rosiglitazone, are insulin-sensitizing agents available for treatment of type 2 diabetes. Large clinical trials have demonstrated the effectiveness of both metformin and pioglitazone in reducing cardiovascular morbidity and mortality. The fixed-dose combination of metformin and pioglitazone appears to be a good option for treating diabetes in insulin-resistant patients.Aims: The purpose of this article is to review the place in therapy of a fixed-dose combination of pioglitazone and metformin in the management of patients with type 2 diabetes.Evidence review: The current evidence suggests that combined therapy may help to achieve the recommended goals in the management of diabetes. A fixed-dose formulation of pioglitazone and metformin may provide advantages in terms of glycemic control and other cardiovascular risk factors frequently associated with diabetes.Place in therapy: The current evidence shows that a fixed-dose formulation of pioglitazone and metformin offers an effective option for the management of patients with type 2 diabetes when monotherapy fails in the achievement of the recommended standards of care.Key words: cardiovascular risk factors, diabetes, pioglitazone, metformin, outcomes.

Young people are unlikely, however, to seek professional treatment for their problems, increasing their chance of serious long-term problems such as impaired peer relations and low self-esteem. The barriers young people face to accessing services are well documented, and self-help resources may provide an alternative option to respond to early manifestations of anxiety disorders. This article reviews the potential benefits of self-help treatments for anxiety and the evidence for their effectiveness. Despite using inclusive review criteria, only six relevant studies were found. The results of these studies show that there is some evidence for the use of self-help interventions for anxiety in young people, but like the research with adult populations, the overall quality of the studies is poor and there is need for further and more rigorous research.Keywords: adolescent, young adult, children, mental disorder, self-administered, bibliotherapy, therapist-guided

    We introduce a new space VLBI project, the Second VLBI Space Observatory Program (VSOP2), following the success of the VLBI Space Observatory Program (VSOP1). VSOP2 has 10 times higher angular resolution, up to about 40 micro arcseconds, 10 times higher frequency up to 43 GHz, and 10 times higher sensitivity compared to VSOP1. Then VSOP2 should become a most powerful tool to observe innermost regions of AGN and astronomical masers. ASTRO-G is a spacecraft for VSOP2 project constructing in ISAS/JAXA since July 2007. ASTRO-G will be launched by JAXA H-IIA rocket in fiscal year 2012. ASTRO-G and ground-based facilities are combined as VSOP2. To achieve the good observation performances, we must realize new technologies. They are large precision antenna, fast-position switching capability, new LNAs, and ultra wide-band down link, etc.. VSOP2 is a huge observation system involving ASTRO-G, ground radio telescopes, tracking stations, and correlators, one institute can not prepare a whole system of VSOP2. Then we mu...

  8. The Astro-E2 X-ray spectrometer/EBIT microcalorimeter x-ray spectrometer

    International Nuclear Information System (INIS)

    The x-ray spectrometer (XRS) instrument is a revolutionary nondispersive spectrometer that will form the basis for the Astro-E2 observatory to be launched in 2005. We have recently installed a flight spare XRS microcalorimeter spectrometer at the EBIT-I and SuperEBIT facility at LLNL replacing the XRS from the earlier Astro-E mission and providing twice the resolving power. The XRS microcalorimeter is an x-ray detector that senses the heat deposited by the incident photon. It achieves a high energy resolution by operating at 0.06 K and by carefully engineering the heat capacity and thermal conductance. The XRS/EBIT instrument has 32 pixels in a square geometry and achieves an energy resolution of 6 eV at 6 keV, with a bandpass from 0.1 to 12 keV (or more at higher operating temperature). The instrument allows detailed studies of the x-ray line emission of laboratory plasmas. The XRS/EBIT also provides an extensive calibration 'library' for the Astro-E2 observatory

    The Astro-E2 high resolution X-Ray Spectrometer (XRS) is expected to provide a major enhancement in study of clusters of galaxies. Astro-E2 is the fifth Japanese X-ray astronomy observatory, which is scheduled for launch in early 2005. The XRS instrument, developed under a Japan-US collaboration, is an X-ray microcalorimeter with a capability of observing extended objects, and a high energy resolution of about 6 eV at 6 keV. The spectral resolving power is 20 times higher than CCDs over the 0.5--10 keV energy band. We have obtained several new results of clusters with Chandra and XMM, which show that high-resolution imaging spectroscopy can clarify some outstanding questions. New sciences from Astro-E2 include the first clear measurement of gas velocities, determination of ion and electron temperatures, and electron densities based on the resolved line features. We will describe the XRS instrument design, and present simulations of the expected performance.

In this review, we summarize the in vitro data, pharmacology, mechanisms of action and resistance, and clinical trial data relating to the use of this agent combined with ceftazidime for the treatment of Gram-negative bacterial infections. The addition of avibactam to ceftazidime improves its in vitro activity against Enterobacteriaceae and Pseudomonas aeruginosa. Avibactam does not improve the activity of ceftazidime against Acinetobacter spp., Burkholderia spp., or most anaerobic Gram-negative rods. Pharmacodynamic data indicate that ceftazidime–avibactam is bactericidal at concentrations achievable in human serum. Animal studies demonstrate that ceftazidime–avibactam is effective in ceftazidime-resistant Gram-negative septicemia, meningitis, pyelonephritis, and pneumonia. Limited clinical trials published to date have reported that ceftazidime–avibactam is as effective as therapy with a carbapenem in complicated urinary tract infection and complicated intra-abdominal infection (combined with metronidazole including infection caused by cephalosporin-resistant Gram-negative isolates. Safety and tolerability of ceftazidime–avibactam in clinical trials has been excellent, with few serious drug-related adverse events reported. Given the abundant clinical experience with ceftazidime and the significant improvement that avibactam provides in its activity against contemporary β-lactamase-producing Gram-negative pathogens, it is likely this new combination agent will play a role in the empiric treatment of complicated

    Full Text Available Luigi Celio, Monica Niger, Francesca Ricchini, Francesco Agustoni Medical Oncology Unit 1, Department of Medical Oncology, Fondazione IRCCS Istituto Nazionale Tumori, Milan, Italy Introduction: The second-generation 5-hydroxytryptamine-3 (5-HT3 receptor antagonist palonosetron is effective in the prevention of chemotherapy-induced nausea and vomiting (CINV associated with highly and moderately emetogenic chemotherapy (HEC and MEC, respectively. In addition, palonosetron has been the first and, at present, the only 5-HT3 receptor antagonist to have a specific indication for the prevention of delayed CINV associated with MEC. The unique pharmacology of this antagonist is thought to partly explain its improved efficacy against delayed symptoms. Aims: To review the evidence underlying the use of palonosetron in preventing CINV. Evidence review: A recent meta-analysis consistently showed that palonosetron significantly increases the control of both emesis and nausea during the acute and delayed phases after single-day HEC or MEC. Consistent with these findings from trials that did not include an neurokinin-1 (NK-1 receptor antagonist, randomized controlled trials recently showed that a triple combination with palonosetron achieves significantly better control of delayed CINV, particularly delayed nausea, in patients undergoing HEC or the high-risk combination of an anthracycline and cyclophosphamide (AC. Evidence from randomized studies also supports palonosetron as a valuable option to reduce the total corticosteroid dose administered in patients undergoing multiple cycles of MEC or AC chemotherapy. Additional benefits of palonosetron include the lack of a warning on cardiac safety and no known clinically significant drug–drug interactions. Place in therapy and conclusion: Evidence currently available indicates that palonosetron significantly adds to the clinician’s ability to effectively control CINV in patients undergoing HEC or MEC. It is

    The increasing prevalence of obesity in the United States (US) is well documented and presents a significant challenge for healthcare providers working with under-resourced communities that often face great obstacles to health-related weight loss. Specifically, it has been reported that obesity disproportionately affects US Latino communities. Yet, little is known about what obesity lifestyle interventions currently exist. Healthcare professionals working in predominantly Latino communities might be interested in learning about the designs and outcomes of existing lifestyle interventions that have been specifically tailored for Latino communities. Here, we report the results of a systematic review of obesity lifestyle interventions targeting Latino adults. We examine the designs and outcomes of the nine articles that met our inclusion criteria. All the studies had physical activity and/or nutritional education components, measurements of both crude weight loss and body mass index (BMI), and some used culturally relevant intervention designs. Two of the nine studies reported significant between-group differences in BMI. Significant barriers between studies include small sample size, low retention rate, enrollment, low adherence, differences in control group activities, and differences in outcomes measured. We recommend that future obesity interventions select and report BMI, raw weight, and body fat percentage as outcome variables and that multiple measurements over multiple days be recorded for pre- and post-intervention data points.

    Pulmonary embolism (PE) is a relatively common cardiovascular emergency. PE and deep vein thrombosis (DVT) are considered expressions of the same disease, termed as venous thromboembolism (VTE). In the present review, we describe and meta-analyze the efficacy and safety data available with the direct oral anticoagulants (DOAC; dabigatran, rivaroxaban, apixaban, edoxaban) in clinical trials testing these new compounds in the acute/long-term and extended therapy of VTE, providing subgroup analyses in patients with index PE. We analyzed ten studies in 35,019 randomized patients. A total of 14,364 patients (41%) had index PE. In the acute/long-term treatment of VTE, the DOAC showed comparable efficacy in preventing recurrent VTE to standard treatment in patients with index PE (risk ratio [RR]: 0.88; 95% confidence interval [CI]: 0.70-1.11) and index DVT (RR: 0.93; 95% CI: 0.75-1.16) (P for subgroup differences =0.76). VTE recurrence depending on PE anatomical extension and presence/absence of right ventricular dysfunction was only reported in two trials, with results being consistent with those obtained in the overall study populations. In the single trial comparing extended therapy of VTE with DOAC versus warfarin, the point estimate for recurrent VTE tended to disfavor the DOAC in patients with index PE (RR: 2.05; 95% CI: 0.83-5.03) and in patients with index DVT (RR: 1.11; 95% CI: 0.49-2.50) (P for subgroup differences =0.32). In trials that compared DOAC versus placebo for extended therapy, the reduction in recurrent VTE was consistent in patients with PE (RR: 0.15; 95% CI: 0.01-1.82) and in patients with DVT (RR: 0.25; 95% CI: 0.10-0.61) (P for subgroup differences =0.71). The DOAC were associated with a consistently lower risk of clinically relevant bleeding (CRB) than standard treatment of acute VTE and higher risk of CRB than placebo for extended therapy of VTE regardless of index event. In summary, the DOAC were as effective as, and safer than, standard

Research on scholarly communication is a hot topic indeed; and for librarians, an area of information overload if there ever was one. How to sort out the good from the bad; the research that is high quality from that which is biased?At this point in time, it is my view that the research does not yet provide a definitive answer for how libraries should approach new models of scholarly communication. We are in the middle of a debate, in the middle of a surge of research, and an ever-changing lens in which we view and approach this topic.

  2. Teaching ASTRO 101 Students the Art of Scientific Argumentation

    2016-01-01

    Going beyond asking students to simply memorize facts about the universe, a longstanding challenge in teaching astronomy centers on successfully teaching students about the nature of science. As introductory astronomy survey courses, known widely as ASTRO 101, can sometimes be the last science course non-science majoring undergraduates take, many faculty hope to emphasize the scientific enterprise as a broad field in inquiry making valuable contributions to civilization as a whole, rather than as an isolated study of objects far from Earth. Scholars have long proposed that an understanding of the nature of science as a human endeavor requires explicit instruction. In other words, students successfully learning the facts of astronomy does not in any way ensure that students will learn anything about the nature of how astronomy is done. In a purposeful effort to improve students' understanding about the practices and discourse of astronomy, scholars working with the CAPER Center for Astronomy & Physics Education research are developing a suite of carefully designed instructional sequences—called Scientific Argumentation—focused on teaching students the differences between data and evidence, how to communicate and defend evidence-based conclusions, and how to be informed skeptics of scientific claims. Early results show students moving from naïve understandings of scientific practices to more informed understandings as well as demonstrating enhanced value for science in general as an worthwhile human endeavor with far reaching benefits.

    2016-08-01

    AstroVis enables rapid visualization of large data files on platforms supporting the OpenGL rendering library. Radio astronomical observations are typically three dimensional and stored as data cubes. AstroVis implements a scalable approach to accessing these files using three components: a File Access Component (FAC) that reduces the impact of reading time, which speeds up access to the data; the Image Processing Component (IPC), which breaks up the data cube into smaller pieces that can be processed locally and gives a representation of the whole file; and Data Visualization, which implements an approach of Overview + Detail to reduces the dimensions of the data being worked with and the amount of memory required to store it. The result is a 3D display paired with a 2D detail display that contains a small subsection of the original file in full resolution without reducing the data in any way.

    Despite improved awareness and quality of care among health care personnel, pressure ulcers prevalence remains high especially in the inpatient setting. Pressure ulcers are associated with increased morbidity and mortality, affecting the quality of life of patients and their caregivers, and significantly increasing direct and indirect healthcare costs. Early risk assessment for developing a pressure ulcer is essential to decide on the appropriate preventive measures and for initiation of a tailored therapeutic approach. Interventions include strategies to reduce extrinsic and intrinsic risk factors associated with tissue ischemia, optimization of patient's nutritional status, and local wound care. This revision intends to review current evidence-based therapeutic interventions in pressure ulcer care, and support implementation of management protocols in an inpatient ward. PMID:16987441

    Emergency department (ED) crowding has become a major barrier to receiving timely care. King Faisal Specialist Hospital & Research Center, Saudi Arabia worked on identifying evidence based strategies for reducing the ED crowding by improving the intake. In addition to a review of literature, qualitative survey methods were used to identify strategies, which were classified into 10 suggested procedures categorized into three types of changes. Physical improvements include using physician cubicles, creating a team triage area and an internal waiting area for less acute patients instead of occupying beds. Technology improvements; include using informatics to update the electronic emergency record with information, using palmar scanning to instantly identify patients and using radio communication devices. Process improvements; include a scribe program to decrease clerical documentation tasks, switching between low flow and high flow processes, placing a physician in triage and using patient segmentation methods.

    Full Text Available American recognition for medical pluralism arrived in 1991. The National Center for Complementary and Alternative Medicine was established under the National Institutes of Health in 1998. Following this, patients and researchers began exploring use of integrative medicine. Terence Ryan with Gerry Bodeker in Europe, Brian Berman in America, and the Indian council of Medical Research advocated traditional medicine and integrative medicine. The Institute of Applied Dermatology (IAD, Kerala has developed integrated allopathic (biomedical and ayurvedic therapies to treat Lymphatic Filariasis, Lichen planus, and Vitiligo. Studies conducted at the IAD have created a framework for evidence-based and integrative dermatology (ID. This paper gives an overview of advances in ID with an example of Lichen Planus, which was examined jointly by dermatologists and Ayurveda doctors. The clinical presentation in these patients was listed in a vikruthi table of comparable biomedical terms. A vikruthi table was used for drug selection in ayurvedic dermatology. A total of 19 patients were treated with ayurvedic prescriptions to normalize the vatha-kapha for 3 months. All patients responded and no side effects were recorded. In spite of advancing knowledge on ID, several challenges remain for its use on difficult to treat chronic skin diseases. The formation of new integrative groups and financial support are essential for the growth of ID in India.

    2014-01-01

    In this white paper we describe the prospects for ASTRO-H for the study of outflows from active galactic nuclei. The most important breakthroughs in this field are expected to arise from the high spectral resolution and sensitivity in the Fe-K band, combined with broad-band sensitivity over the full X-ray band and spectral capabilities also at lower energies. The sensitivity in the Fe-K region allows to extend the absorption measure distribution of the outflow out to the highest ionisation states accessible, where observations with current X-ray missions indicate that most of the outflowing gas is to be found. Due to the high-resolution and sensitivity it will also be able to give the definitive proof for the existence of ultra-fast outflows, and if so, characterise their physical properties in great detail. These ultra-fast outflows carry very large amounts of energy and momentum, and are of fundamental importance for feedback studies. We show how the ASTRO-H observations in general can help to constrain num...

    2008-07-01

    Full Text Available Despite the fact that nursing research has been developed in Greece, nevertheless the provision of nursing care is not based on current research findings, but rather on the knowledge gained by nurses during their undergraduate education. The transition of medicine in the last decade towards evidence based practice had definitely an impact on the nursing profession.The aim of this article is to briefly present evidence based nursing as a process and perspective to Greek nurses.Method: A literature search was performed in order to identify and review relevant articles concerning evidence based nursing.Conclusions: It has been supported that in the practice of evidence based nursing, a nurse has to decide whether the evidence is relevant for the individual patient. The incorporation of clinical expertise should balance the risks and benefits of a possible treatment and take into consideration the patient’s unique clinical circumstances and preferences. The stages to identify evidence for nursing practice follow firstly a question which must be addressed for a particular clinical problem. Then, a literature search is performed in order to access the evidence and critically appraise it and finally the best available evidence that fits into a particular case is utilized. Evidence based nursing bears benefits for patients, nurses and health care services, as well. In the process of implementing evidence based nursing in Greece there are several constraints. Taking these difficulties into consideration and until Greek nurses familiarize themselves with evidence based nursing care, it is necessary to constitute workgroups of nurse researchers aiming at forming clinical guidelines for nursing practice, which will based on the best available evidence.

    Full Text Available There is controversy in the literature regarding a number of topics related to anterior cruciate ligament (ACLreconstruction. The purpose of this article is to answer the following questions: 1 Bone patellar tendon bone (BPTB reconstruction or hamstring reconstruction (HR; 2 Double bundle or single bundle; 3 Allograft or authograft; 4 Early or late reconstruction; 5 Rate of return to sports after ACL reconstruction; 6 Rate of osteoarthritis after ACL reconstruction. A Cochrane Library and PubMed (MEDLINE search of systematic reviews and meta-analysis related to ACL reconstruction was performed. The key words were: ACL reconstruction, systematic reviews and meta-analysis. The main criteria for selection were that the articles were systematic reviews and meta-analysesfocused on the aforementioned questions. Sixty-nine articles were found, but only 26 were selected and reviewed because they had a high grade (I-II of evidence. BPTB-R was associated with better postoperative knee stability but with a higher rate of morbidity. However, the results of both procedures in terms of functional outcome in the long-term were similar. The double-bundle ACL reconstruction technique showed better outcomes in rotational laxity, although functional recovery was similar between single-bundle and double-bundle. Autograft yielded better results than allograft. There was no difference between early and delayed reconstruction. 82% of patients were able to return to some kind of sport participation. 28% of patients presented radiological signs of osteoarthritis with a follow-up of minimum 10 years.

    Full Text Available Objective - To demonstrate how evidence based practice has contributed to informaing decisions and resolving issues if concern in service delivery at Bond University Librray. Methods - This paper critically analyses three evidence based research projects conducted at Bond University Library. Each project combined a range of research methods including surveys, literature reviews and the analysis of internal performance data to find solutions to problems in library service delivery. The first research project investigated library opening hours and the feasability of twenty-four hour opening. Another project reseached questions about the management of a collection of feature films on DVD and video. The thrd project investigated issues surrounding the teaching of EndNote to undergarduate students. Results - Despite some deficiencies in the methodologies used, each evidence based research project had positive outcomes. One of the highlights asn an essential feature of the process at Bond University Library was the involvement of stakeholders. The ability to build consensus and agree action plans with stakeholders was an important outcome of that process. Conclusion - Drawing on the experience of these research projects, the paper illustrates the benefits of evidence based information practice to stimulate innovation and improve library services. Librarians, like most professionals, need to continue to develop the skills and a culture to effectively carry out evidence based practice.

    The X-Ray Spectrometer (XRS) instrument, scheduled to be launched as part of the Japanese X-ray astronomy satellite Astro-E in February 2000, has an array of 32 microcalorimeters at the focal plane. These calorimeters consist of ion-implanted silicon thermistors and HgTe thermalizing X-ray absorbers. These devices provide spectral resolution of 9 eV at 3 keV and 11 eV at 6 keV. The process of determining the detector parameters for this instrument will be discussed. This will include discussion of the array layout, thermal conductance of the link to the heat sink, operating temperature, thermistor size, absorber choice, and means of attaching the absorber to the thermistor bearing element. We consider the XRS calorimeters to be operating in a local optimum, with the absolute optimization yet to be performed, thus we will discuss directions for future development of this sensor technology.

  10. The microcalorimeter spectrometer on the ASTRO-E X-ray observatory

    International Nuclear Information System (INIS)

    The Astro-E Observatory will employ a high-resolution X-ray spectrometer based on a 32 pixel array of microcalorimeters with an energy resolution of about 12 eV at 6 keV (the Fe-K region). This will provide spectral resolving power 10 times higher than any other non-dispersive X-ray spectrometer. The instrument incorporates a three-stage cooling system capable of maintaining the temperature of the detector stage at 60 mK for about two years in orbit with a 97% duty cycle. The array sits at the focus of a grazing incidence conical mirror. The quantum efficiency of the microcalorimeters and the reflectivity of the X-ray mirror system combine to give high throughput over the 0.3-12 keV energy band. This new capability will enable the study of a wide range of high-energy astrophysical sources with unprecedented spectral sensitivity

    International Nuclear Information System (INIS)

    We measured the optical and the X-ray transmission of the optical blocking filters for the X-ray Imaging Spectrometers (XISs) which are the X-ray CCD cameras of the ASTRO-E satellite. We conclude that the oxidation of the aluminum reduces the optical transmission down to ∼60-70% of the theoretical value of the aluminum. We achieved optical transmission below 5x10-5 in the range from 4000 to 9500 A by using aluminum thickness of 1200 A, while the theoretical calculation requires 800 A. The measurement of absolute quantum efficiency of XIS is also performed at several particular energies. We confirmed 20% quantum efficiency at 0.5 keV for the XIS engineering model (XIS EM)

    The availability of low-cost, high-performance computing hardware and software has transformed the manner by which astronomical concepts can be re-discovered and explored in a laboratory that accompanies an astronomy course for arts students. We report on a strategy, begun in 1992, for allowing each student to understand fundamental scientific principles by interactively confronting astronomical and physical phenomena, through direct observation and by computer simulation. These experiments have evolved as :a) the quality and speed of the hardware has greatly increasedb) the corresponding hardware costs have decreasedc) the students have become computer and Internet literated) the importance of computationally and scientifically literate arts graduates in the workplace has increased.We present the current suite of laboratory experiments, and describe the nature, procedures, and goals in this two-semester laboratory for liberal arts majors at the Astro 101 university level.

  15. Sicily statement on evidence-based practice

    Directory of Open Access Journals (Sweden)

    Hopayian Kevork

    2005-01-01

    Full Text Available Abstract Background A variety of definitions of evidence-based practice (EBP exist. However, definitions are in themselves insufficient to explain the underlying processes of EBP and to differentiate between an evidence-based process and evidence-based outcome. There is a need for a clear statement of what Evidence-Based Practice (EBP means, a description of the skills required to practise in an evidence-based manner and a curriculum that outlines the minimum requirements for training health professionals in EBP. This consensus statement is based on current literature and incorporating the experience of delegates attending the 2003 Conference of Evidence-Based Health Care Teachers and Developers ("Signposting the future of EBHC". Discussion Evidence-Based Practice has evolved in both scope and definition. Evidence-Based Practice (EBP requires that decisions about health care are based on the best available, current, valid and relevant evidence. These decisions should be made by those receiving care, informed by the tacit and explicit knowledge of those providing care, within the context of available resources. Health care professionals must be able to gain, assess, apply and integrate new knowledge and have the ability to adapt to changing circumstances throughout their professional life. Curricula to deliver these aptitudes need to be grounded in the five-step model of EBP, and informed by ongoing research. Core assessment tools for each of the steps should continue to be developed, validated, and made freely available. Summary All health care professionals need to understand the principles of EBP, recognise EBP in action, implement evidence-based policies, and have a critical attitude to their own practice and to evidence. Without these skills, professionals and organisations will find it difficult to provide 'best practice'.

    The phenomenon of the physical, moral or psychical violence in the working environment, variously indicated as "mobbing", "workplace bullying" or "workplace harassment", is to date object of numerous studies, mostly of epidemiological type, which are yet to clear, in a sufficient way, the aspects of that phenomenon, the possible causes, risk factors, constituent characteristics and consequences. Our search, a systematic review of the existing studies in literature and a meta-analysis of the jobs chosen to such scope, has shown that only a small percentage of the researches conducted on the topic is represented from studies that collected original information on the subject. The results of the meta-analysis show that in the category of the mobbed workers the psychosomatic disturbs, stress, and anxiety are greater than in the group of controls and that the perception of the surrounding environment is more negative in the victims of mobbing compared with the not mobbed workers. The value of such results is reduced by the characteristics and the heterogeneity of the studies. PMID:17886755

    2006-09-01

    Full Text Available Abstract Background The reduction of health inequalities is a focus of many national and international health organisations. The need for pragmatic evidence-based approaches has led to the development of a number of evidence-based equity initiatives. This paper describes a new program that focuses upon evidence- based tools, which are useful for policy initiatives that reduce inequities. Methods This paper is based on a presentation that was given at the "Regional Consultation on Policy Tools: Equity in Population Health Reports," held in Toronto, Canada in June 2002. Results Five assessment tools were presented. 1. A database of systematic reviews on the effects of educational, legal, social, and health interventions to reduce unfair inequalities is being established through the Cochrane and Campbell Collaborations. 2 Decision aids and shared decision making can be facilitated in disadvantaged groups by 'health coaches' to help people become better decision makers, negotiators, and navigators of the health system; a pilot study in Chile has provided proof of this concept. 3. The CIET Cycle: Combining adapted cluster survey techniques with qualitative methods, CIET's population based applications support evidence-based decision making at local and national levels. The CIET map generates maps directly from survey or routine institutional data, to be used as evidence-based decisions aids. Complex data can be displayed attractively, providing an important tool for studying and comparing health indicators among and between different populations. 4. The Ottawa Equity Gauge is applying the Global Equity Gauge Alliance framework to an industrialised country setting. 5 The Needs-Based Health Assessment Toolkit, established to assemble information on which clinical and health policy decisions can be based, is being expanded to ensure a focus on distribution and average health indicators. Conclusion Evidence-based planning tools have much to offer the

    AstroCom NYC is an undergraduate mentoring program designed to improve urban minority student access to opportunities in astrophysical research by greatly enhancing partnerships between research astronomers in New York City (City University of New York - an MSI, American Museum of Natural History, and Columbia). AstroCom NYC provides centralized, personalized mentoring as well as financial and academic support, to CUNY undergraduates throughout their studies, plus the resources and opportunities to further CUNY faculty research with students. The goal is that students' residency at AMNH helps them build a sense of belonging in the field, and readies and inspires them for graduate study. AstroCom NYC provides a rigorous Methods of Scientific Research course developed specifically to this purpose, a laptop, research and career mentors, outreach activities, scholarships and stipends, Metrocards, and regular assessment for maximum effectiveness. The goal of this support is to remove barriers to access and success. AMNH serves as the central hub for our faculty and students, who are otherwise dispersed among all five boroughs of the City. We welcomed our third and largest cohort last year, along with 13 additional students through a NASA community college initiative. We review plans for Year 4, when we expect all of our interns to compete for external summer REUs, and our growing participation and leadership within partner activities.

    Interactive lecture demonstrations (ILDs) have repeatedly shown to be effective tools for improving student achievement in the context of learning physics. As a first step toward systematic development of interactive lecture demonstrations in ASTRO 101, the introductory astronomy survey course, a systematic review of education research, describing educational computer simulations (ECSs) reveals that initial development requires a targeted study of how ASTRO 101 students respond to ECSs in the non-science majoring undergraduate lecture setting. In this project we have adopted the process by which ILDs were designed, pilot-tested, and successfully implemented in the context of physics teaching (Sokoloff & Thornton, 1997; Sokoloff & Thornton, 2004). We have designed the initial pilot-test set of ASTRO 101 ILD instructional materials relying heavily on ECSs. Both an instructor’s manual and a preliminary classroom-ready student workbook have been developed, and we are implementing a pilot study to explore their effectiveness in communicating scientific content, and the extent to which they might enhance students’ knowledge of and perception about astronomy and science in general. The study design uses a pre-/post-test quasi-experimental study design measuring students’ normalized gain scores, calculated as per Hake (1998) and Prather (2009), using a slightly modified version of S. Slater’s (2011) Test Of Astronomy STandards TOAST combined with other instruments. The results of this initial study will guide the iterative development of ASTRO 101 ILDs that are intended to both be effective at enhancing student achievement and easy for instructors to successfully implement.

Medicare Australia had 18,262 doctors it deemed eligible; 14,000 of these were selected for a stratified random sample. Subjects were randomized to one of 7 groups of 2,000 each. Each group received a different letter offering two years of free access to BMJ Clinical Evidence, an evidence based online information tool. Randomization was done electronically, and the seven groups were stratified by age group, gender, and location. The interventions given to each group differed as follows:• Group 1: Received a letter offering 2 years of free access, with no further demands on the recipient.• Group 2: Received a letter offering 2 years of free access, but on the condition that they complete an initial questionnaire and another one at 12 months, as well as allowing the publisher to provide de-personalized usage data to the researchers.• Group 3: Same as Group 2, but with the additional offer of an online tutorial to assist them with using the resource.• Group 4: Same as Group 2, but with an additional pamphlet with positive testimonials about the resource from Australian medical opinion leaders.• Group 5: Same as Group 2, but with an additional offer of professional development credits towards their required annual totals.• Group 6: Same as Group 2, but with an additional offer to be entered to win a prize of $500 towards registration at a

    Evidence based library and information practice (EBLIP) is a strategy to bridge research and practice. Generally EBLIP is seen as a movement to encourage and give practitioners the means to incorporate research into their practice, where it previously may have been lacking. The widely accepted definition of EBLIP (Booth, 2000) stresses three aspects that contribute to a practice that is evidence based: 1) "the best available evidence;" 2) "moderated by user needs and preferences;" 3) "applied...

    Evidence based practice, whether in librarianship or any other profession, depends on access to the evidence, and access to opportunities to share one’s own evidence. Open access (OA) is the perfect complement to evidence based librarianship. OA provides the optimum access to the evidence for librarians everwhere, and the optimum means of dissemination. This article compares examines access to the LIS literature in the print and electronic media, and the impact of open access.

    systematic reviews as well as using “explode” and “focus”, which tied for the lowest rating. The observed searches on average were rated lower than the self-assessments on all but one parameter. None of the average scores for either the self-rating or the observer-rating approached “highly skilled”. Conclusion – The authors concluded that the information literacy instruction the participants received as undergraduates did not prepare them adequately for evidence-based practice. Even though most participants said they remembered their undergraduate information literacy instruction, neither the average scores for the self-rating nor the observer-rating approached “highly skilled”. From that they could surmise that the attainment of information literacy should be a career-long learning process, beginning with undergraduate instruction and extending throughout one’s clinical practice.The authors also found that the level of instruction cohorts received as undergraduates did not seem to correspond to their current ability. Cohort 1, who received no information literacy instruction as undergraduates, scored higher on average than cohorts 3 and 4 on the self-assessment and higher than cohorts 3, 4, and 5 on the observer assessment. Cohort 1 also used more evidence based sources than did cohort 4, who received the most training on evidence-based medicine. Cohorts 1 and 2 reported the most postgraduate information literacy instruction, leading the authors to postulate that the further along one is in his medical career, the more important evidence based practice, and thus information literacy instruction, becomes. Even with additional instruction, however, the participants did not seem prepared for evidence-based practice. The authors concluded that information literacy instruction during postgraduate training and clinical practice—possibly giving the doctor’s specialty consideration when designing instruction—might be more important than undergraduate

    It is important to ensure that cancer pain management is based on the best evidence. Nursing evidence-based pain management can be examined through an evaluation of pain documentation. The aim of this study was to modify and test an evaluation tool for nursing cancer pain documentation, and describe the frequency and quality of nursing pain documentation in one oncology unit via the electronic medical system. A descriptive cross-sectional design was used for this study at an oncology unit of an academic medical center in the Pacific Northwest. Medical records were examined for 37 adults hospitalized during April and May 2013. Nursing pain documentations (N = 230) were reviewed using an evaluation tool modified from the Cancer Pain Practice Index to consist of 13 evidence-based pain management indicators, including pain assessment, care plan, pharmacologic and nonpharmacologic interventions, monitoring and treatment of analgesic side effects, communication with physicians, and patient education. Individual nursing documentation was assigned a score ranging from 0 (worst possible) to 13 (best possible), to reflect the delivery of evidence-based pain management. The participating nurses documented 90% of the recommended evidence-based pain management indicators. Documentation was suboptimal for pain reassessment, pharmacologic interventions, and bowel regimen. The study results provide implications for enhancing electronic medical record design and highlight a need for future research to understand the reasons for suboptimal nursing documentation of cancer pain management. For the future use of the data evaluation tool, we recommend additional modifications according to study settings. PMID:26256215

    Intramuscular injections require a thorough and meticulous approach to patient assessment and injection technique. This article, the second in a series of two, reviews the evidence base to inform safer practice and to consider the evidence for nursing practice in this area. A framework for safe practice is included, identifying important points for safe technique, patient care and clinical decision making. It also highlights the ongoing debate in selection of intramuscular injection sites, predominately the ventrogluteal and dorsogluteal muscles. PMID:25249123

    2009-01-01

    The idea that policy should be based on best research evidence might appear to be self-evident. But a closer analysis reveals a number of problems and paradoxes inherent in the concept of "evidence-based policymaking." The current conflict over evidence-based policymaking parallels a long-standing "paradigm war" in social research between positivist, interpretivist, and critical approaches. This article draws from this debate in order to inform the discussions over the appropriateness of evidence- based policymaking and the related question of what is the nature of policymaking. The positivist, empiricist worldview that underpins the theory and practice of evidence-based medicine (EBM) fails to address key elements of the policymaking process. In particular, a narrowly "evidence-based" framing of policymaking is inherently unable to explore the complex, context-dependent, and value-laden way in which competing options are negotiated by individuals and interest groups. Sociolinguistic tools such as argumentation theory offer opportunities for developing richer theories about how policymaking happens. Such tools also have potential practical application in the policymaking process: by enhancing participants' awareness of their own values and those of others, the quality of the collective deliberation that lies at the heart of policymaking may itself improve.

    ASTRO-H is a powerful new X-ray observatory for the community: starting approximately 9 month after launch, the bulk of the observing time will belong to guest observers (GOs) to be allocated via an international Guest Observer program. For US-based observers, the first call for proposals is a part of ROSES-2016, while there are parallel calls for proposals by ESA for European astronomers, and by ISAS/JAXA for the Japanese community and all other researchers not in the US or in an ESA member country.We will present the parameters of the Cycle 1 Call for Proposals, concentrating on US-specific details as appropriate. We will discuss the international division of observing time, the relationship with the on-going performance verification (PV) phase observations, our expectation for the number of US targets to be accepted and the financial support that will be available, and the timeline including the proposal deadline and expected period of Cycle 1 observations

    The alpha magnetic spectrograph (AMS) is a composite particle detector to be accommodated on the International Space Station (ISS). AMS is mainly devoted to galactic, charged cosmic rays studies, antimatter and dark matter searches. Besides the main, classical physics goals, capabilities in the field of GeV and multi-GeV gamma astrophysics have been established and are under investigation by a number of groups. Due to the unsteadiness of the ISS platform, a star-mapper device is required in order to fully exploit the intrinsic arc-min angular resolution provided by the silicon tracker. A star-mapper is conceptually an imaging, optical instrument able to autonomously recognize a stellar field and to calculate its own orientation with respect to an inertial reference frame. AMICA (Astro Mapper for Instruments Check of Attitude) on AMS is responsible for providing real-time information that is going to be used off-line for compensating the large uncertainties in the ISS flight attitude and the structural degrees of freedom. In this paper, we describe in detail the AMICA sub-system, the accommodation/integration issues and the in-flight alignment procedure adopting identified galactic (Pulsars) and extra-galactic (AGNs) sources.

    X-ray observations provide a powerful tool to probe the central engines of active galactic nuclei (AGN). A hard X-ray continuum is produced from deep within the accretion flow onto the supermassive black hole, and all optically thick structures in the AGN (the dusty torus of AGN unification schemes, broad emission line clouds, and the black hole accretion disk) "light up" in response to irradiation by this continuum. This White Paper describes the prospects for probing AGN physics using observations of these X-ray reflection signatures. High-resolution SXS spectroscopy of the resulting fluorescent iron line in type-2 AGN will give us an unprecedented view of the obscuring torus, allowing us to assess its dynamics (through line broadening) and geometry (through the line profile as well as observations of the "Compton shoulder"). The broad-band view obtained by combining all of the ASTRO-H instruments will fully characterize the shape of the underlying continuum (which may be heavily absorbed) and reflection/sc...

    The X-Ray Spectrometer (XRS) will be launched in February 2005 as part of the Astro-E2 mission. It will provide unprecedented throughput and resolving powers particularly at high energies. In this presentation we will describe the in-flight calibration program. The energy scale of the XRS is a complex, non-linear function of the noise and power conditions on the array. It will be calibrated empirically using the bright point sources, Capella and GX301-2. Ground calibration of the line spread function show it to be almost perfectly Gaussian. The in-flight calibration is designed to verify this using the energy scale targets. The effective area curve of the XRS contains discreet edge structure from the mirrors, the optical blocking filters, and the microcalorimeter HgTe absorbers. The effective area Calibration program will simultaneously measure these absorption edges and the global effective area properties using the relatively featureless sources 3C273 and Mrk421. Additional monitoring of any ice build-up on the filters will be conducted using observations of the supernova remnants N132D and E0102.

    The idea of evidence- based practice is influential in public welfare services, including education. The idea is controversial, however, not least because it involves a poten tial redefinition of the relation ship between knowledge, authority and professionalism. This is discussed based on a study...... of evidence- based methods in Danish pre-school education and care. The management sees the use of these methods as strengthening pre- school teacher professionalism, but the actual practices in the day-careinstitutions are ambiguous. In some cases, using the methods becomes an end in itself and...

    2016-01-01

    Obsessive–compulsive disorder (OCD) is a neuropsychiatric illness that often develops in childhood, affects 1%–2% of the population, and causes significant impairment across the lifespan. The first step in identifying and treating OCD is a thorough evidence-based assessment. This paper reviews the administration pragmatics, psychometric properties, and limitations of commonly used assessment measures for adults and youths with OCD. This includes diagnostic interviews, clinician-administered symptom severity scales, self-report measures, and parent/child measures. Additionally, adjunctive measures that assess important related factors (ie, impairment, family accommodation, and insight) are also discussed. This paper concludes with recommendations for an evidence-based assessment based on individualized assessment goals that include generating an OCD diagnosis, determining symptom severity, and monitoring treatment progress.

    This article explores the challenges presented by the mandate for evidence-based practice for family therapists who identify with the philosophical stance of social construction. The history of psychotherapy outcome research is reviewed, as are current findings that provide empirical evidence for an engaged, dialogic practice. The authors suggest that the binary between empiricism and social construction may be unhinged by understanding empiricism as a particular discursive frame (i.e., a particular way of talking, acting, and being in the world), one of many available as a way of understanding and talking about our work. Through a case vignette, the authors introduce the evidence-based practice of Feedback Informed Treatment as an elaboration of social construction, and as an example of bridging the gap between the discursive frames of empiricism and social construction.

    Full Text Available The practice of evidence-based medicine means logical integration of individual clinical experiences with the best available evidences from systematic research. The recent clinical practice tends to apply evidence based procedures instead of individual clinical opinions. True interpretation of laboratory results is important on diagnosis, treatment and follow-up as well as time and cost effectivity. Although clinicians expect decisive and clear results from the laboratory tests, sometimes unexpected results can be seen. Most of these occasions are resulting from demographic properties, obtaining the sample and other external factors rather then laboratory procedures. It is important to know preanalytical variations that affect the laboratory test results to make quick and accurate assessments for the primary care physicians who are getting increasing number of patients. The aim of this review is to introduce a practical source to the primary care physicians by briefing the effects of preanalytical variables on laboratory test results.

    2016-03-01

    Quality control is pervasive in most modern business, but, surprisingly, is in its infancy in medicine in general-and cardiovascular imaging in particular. The increasing awareness of the cost of cardiovascular imaging, matched by a desire to show benefits from imaging to patient outcome, suggests that this deficiency should be reassessed. Demonstration of improved quality has been proposed to require a focus on several domains: laboratory organization, patient selection, image acquisition, image interpretation, and results communication. Improvement in these steps will require adoption of a variety of interventions, including laboratory accreditation, appropriate use criteria, and continuous quality control and enhancements in reporting, but the evidence base for the benefit of interventions on these steps has been sparse. The purpose of this review is to evaluate the current status and future goals of developing the evidence base for these processes in cardiovascular imaging. PMID:26965731

    The Astronomy Peer Advising Leaders program (AstroPAL) provides guidance for incoming grad students from a team of student volunteers who have passed their 2nd year Qualifier Exam. The purpose is to pair first years with a mentor who can help them through some of the stresses or difficulties that come with being a new grad student. AstroPALs and mentees meet privately about once a month in a casual setting to talk about how they're adjusting to the new surroundings, how they're handling the workload, etc. New students can join AstroPAL at any time during their first two years, and can stop receiving guidance once they feel comfortable in the program. Mentees will be assigned an AstroPAL based on preference and availability, and an AstroPAL Liason will always be in place to facilitate mentor reassignments or other issues if necessary. After passing the 2nd year Qualifier Exam, mentees are eligible to serve as mentors to incoming students.

    AstroBetter.com is a multi-contributor blog and wiki website designed for information sharing among professional astronomers. The goal of the site is to increase the productivity of astronomers by creating a centralized location for tips and tools of our multifaceted trade. Our content includes topics related to data reduction and analysis, general computing, writing papers and proposals, giving talks, teaching, career planning, productivity, organization, and diversity and equity in science and education. While we have several contributors, the site is intended to be community driven and we encourage everyone to publish to the wiki, submit guest posts, suggest post ideas, and to comment on blog entries. One of our primary goals is to consolidate and reduce the transient nature of the astronomy community's collective knowledge base by having an active wiki. Currently, the most common way to share astro-centric tools and tips that are not appropriate for a published paper, is to put them on an individual's website. However, the average astronomer's website will have at least four different addresses over the course of their career and only the site owner can edit the content. As a result, information on personal websites goes stale very quickly and deal links to such sites abound. It is our hope that community maintained wikis, such as the one hosted on AstroBetter, will gradually replace the personal website. In this poster we introduce the contributors to AstroBetter, show statistics about our current readership, give excerpts of some of our most popular posts and wiki entries, and show how anyone can add or edit content on the wiki. The goal of this poster is to spread the work about AstroBetter and increase our community of readers and wiki editors, because together, we can AstroBetter.

    AstroGrid is the UK's Virtual Observatory (VO) initiative. It brings together the principal astronomical data centres in the UK, and has been funded to the tune of ˜pounds 5M over the next three years, via PPARC, as part of the UK e--science programme. Its twin goals are the provision of the infrastructure and tools for the federation and exploitation of large astronomical (X-ray to radio), solar and space plasma physics datasets, and the delivery of federations of current datasets for its user communities to exploit using those tools. Whilst AstroGrid's work will be centred on existing and future (e.g. VISTA) UK datasets, it will seek solutions to generic VO problems and will contribute to the developing international virtual observatory framework: AstroGrid is a member of the EU-funded Astrophysical Virtual Observatory project, has close links to a second EU Grid initiative, the European Grid of Solar Observations (EGSO), and will seek an active role in the development of the common standards on which the international virtual observatory will rely. In this paper we shall primarily describe the concrete plans for AstroGrid's one-year Phase A study, which will centre on: (i) the definition of detailed science requirements through community consultation; (ii) the undertaking of a ``functionality market survey" to test the utility of existing technologies for the VO; and (iii) a pilot programme of database federations, each addressing different aspects of the general database federation problem.

    We describe the transmission calibration of the Astro-E XRS blocking filters. The XRS instrument has five aluminized polyimide blocking filters. These filters are located at thermal stages ranging from 200 K to 60 mK. They are each about 1000 A thick. XRS will have high energy resolution which will enable it to see some of the extended fine structure around the oxygen and aluminum K edges of these filters. Thus, we are conducting a high spectral resolution calibration of the filters near these energies to resolve out extended flue structure and absorption lines.

Attention is given to an Astros system overview, a system firmware description, cluster evaluation, guide star selection, exposure time determination, video data input, update interval timing, exposure time sequencing full frame video A/D conversion, analog threshold for acquisition, minimum threshold determination, and the theoretical basis for the track algorithm.

  13. Evidence-based history taking under "time constraint"

    2011-01-01

    Full Text Available Physicians all through the world visit patients under time limitations. The most important troubled clinical skill under "time constraint" is the diagnostic approach. In this situation, clinicians need some diagnostic approaches to reduce both diagnostic time and errors. It seems that highly experienced physicians utilize some special tactics in this regard. Evidence-based medicine (EBM as a relatively new paradigm for clinical practice stresses on using research evidences in diagnostic evaluations. The authors aimed to evaluate experts′ strategies and assess what EBM can add to these tactics. They reviewed diagnostic strategies of some veteran internists in their busy outpatient clinics and proposed an evidence-based diagnostic model engaging clinical experience and research evidence. It appears that every clinician utilizes a set of "key pointer" questions for decision-making. In addition to use of evidence-based resources for making differential diagnosis and estimating utility of various diseases, clinicians should use "key pointers" with significant likelihood ratios and from independent systems to reduce time and errors of history taking. Clinical trainees can improve their practice by constructing their own set of pointers from valid research evidences. Using this diagnostic model, EBM can help physicians to struggle against their "time constraint".

    Background It is important to ensure that cancer pain management is based on the best evidence. Nursing evidence-based pain management can be examined through an evaluation of pain documentation. Aims This study aimed to (a) modify and test an evaluation tool for nursing cancer pain documentation, and (b) describe the frequency and quality of nursing pain documentation in one oncology unit via electronic medical system. Design and Setting A descriptive cross-sectional design was used for this study at an oncology unit of an academic medical center in the Pacific Northwest. Methods Medical records were examined for 37 adults hospitalized during April and May of 2013. Nursing pain documentations (N = 230) were reviewed using an evaluation tool modified from the Cancer Pain Practice Index to consist of 13 evidence-based pain management indicators, including pain assessment, care plan, pharmacologic and nonpharmacologic interventions, monitoring and treatment of analgesic side effects, communication with physicians, and patient education. Individual nursing documentation was assigned a score from 0 (worst possible) to 13 (best possible), to reflect the delivery of evidence-based pain management. Results The participating nurses documented 90% of the recommended evidence-based pain management indicators. Documentation was suboptimal for pain reassessment, pharmacologic interventions, and bowel regimen. Conclusions The study results provide implications for enhancing electronic medical record design and highlight a need for future research to understand the reasons for suboptimal nursing documentation of cancer pain management. For the future use of the data evaluation tool, we recommend additional modifications according to study settings. PMID:26256215

    e-Health is experiencing a difficult time. On the one side, the forecast is for a bright digital health future created by precision medicine and smart devices. On the other hand, most large scale e-health projects struggle to make a difference and are often controversial. Both futures fail because they are not evidence-based. Medical informatics should follow the example of evidence-based medicine, i.e. conduct rigorous research that gives us evidence to solve real world problems, synthesise that evidence and then apply it strictly. We already have the tools for creating a different universe. What we need is evidence, will, a culture of learning, and hard work. PMID:27030221

    Critical thinking (CT) is vital to evidence-based nursing practice. Evidence-based practice (EBP) supports nursing care and can contribute positively to patient outcomes across a variety of settings and geographic locations. The nature of EBP, its relevance to nursing, and the skills needed to support it should be required components of baccalaureate education and must be introduced early in students' development as independent, self-directed learners and as professional nurses. Among the knowledge, skills, and processes needed to support EBP, CT is paramount. The development of CT can prepare nurses with the necessary skills and dispositions (habits of mind, attitudes, and traits) to support EBP. The intents of this study were to explore the importance of CT as an essential skill to support EBP and to describe some of the strategies and processes considered key to the ongoing development of CT.

    This book contains an evidence-based pedagogic guide to enable any motivated teaching/training professional to be able to teach effectively and creatively. It firstly summarises the extensive research field on human psychological functioning relating to learning and how this can be fully utilised in the design and facilitation of quality learning experiences. It then demonstrates what creativity actually 'looks like' in terms of teaching practices, modelling the underpinning processes of creative learning design and how to apply these in lesson planning. The book, having established an evidence-based and pedagogically driven approach to creative learning design, extensively focuses on key challenges facing teaching professionals today. These include utilising information technologies in blended learning formats, differentiating instruction, and developing self-directed learners who can think well. The main purpose of the book is to demystify what it means to teach creatively, explicitly demonstrating the pr...

  19. The fallacy of evidence based policy

    CERN Document Server

    Saltelli, Andrea

    2016-01-01

    The use of science for policy is at the core of a perfect storm generated by the insurgence of several concurrent crises: of science, of trust, of sustainability. The modern positivistic model of science for policy, known as evidence based policy, is based on dramatic simplifications and compressions of available perceptions of the state of affairs and possible explanations (hypocognition). This model can result in flawed prescriptions. The flaws become more evident when dealing with complex issues characterized by concomitant uncertainties in the normative, descriptive and ethical domains. In this situation evidence-based policy may concur to the fragility of the social system. Science plays an important role in reducing the feeling of vulnerability of humans by projecting a promise of protection against uncertainties. In many applications quantitative science is used to remove uncertainty by transforming it into probability, so that mathematical modelling can play the ritual role of haruspices. This epistem...

    Henao, Daniel Eduardo; Jaimes, Fabián Alberto

    2009-03-01

    Evidence-based medicine gathers physician's experience and the best scientific evidence to make medical decisions. This proposal has been widely promulgated by medical opinion leaders. Despite a large literature supporting this practice, a formal discussion has not been established regarding its epistemological consequences in daily medical work. The main proposal of evidence-based medicine consists of choosing the best medical decision according to the best available results from scientific studies. Herein, the goal was to highlight inappropriate application of the scientific method used by physics to clinical science. The inaccuracy resides in describing health and disease in strictly numeric equivalents that can be homogenized on a continuous scale. Finally, the authors consider each diseased human being as a complex system, unique and particular, and that this being is defined by an historical background as well as current actual context. Therefore, evidence-based medicine possesses certain limitations that must be recognized in order to to provide better health care to patients. PMID:19753837

    Anemia is a prevalent disease with multiple possible etiologies and resultant complications. Iron deficiency anemia is a common cause of anemia and is typically due to insufficient intake, poor absorption, or overt or occult blood loss. Distinguishing iron deficiency from other causes of anemia is integral to initiating the appropriate treatment. In addition, identifying the underlying cause of iron deficiency is also necessary to help guide management of these patients. We review the key components to an evidence-based, cost-conscious evaluation of suspected iron deficiency anemia. PMID:27542426

    Healthy People 2020 includes an objective to increase the proportion of elementary, middle, and senior high schools that provide comprehensive school health education to prevent health problems in the following areas: unintentional injury; violence; suicide; tobacco use and addiction; alcohol or other drug use; unintended pregnancy, HIV/AIDS, and sexually transmitted infections (STI); unhealthy dietary patterns; and inadequate physical activity. These specific goals are part of the efforts of Healthy People 2020 to increase the proportion of elementary, middle, and senior high schools that have health education goals or objectives that address the knowledge and skills articulated in the National Health Education Standards. A focus on Pre-K through 12 health education is a prerequisite for the implementation of a coordinated, seamless approach to health education as advocated by the Healthy People Curriculum Task Force and incorporated into the Education for Health framework. To help accomplish these goals, this article views the role of education as part of the broader socioecologic model of health. A comprehensive literature review was undertaken to identify evidence-based, peer-reviewed programs, strategies, and resources. The results of this review are presented organized as sexual health, mental and emotional health, injury prevention, tobacco and substance abuse, and exercise and healthy eating. Evidence-based implementation strategies, often considered the missing link, are recommended to help achieve the Healthy People 2020 objective of increasing the prevalence of comprehensive school health education programs designed to reduce health risks for children.

    2007-11-01

    Evidence-based Medicine (EBM) is the process of systematically reviewing, appraising and using clinical research findings to aid the delivery of optimal clinical care to patients. EBM has become popular due to: the need for valid information about diagnosis, prognosis, therapy and prevention during patient care; traditional sources such as textbooks and expert opinion being frequently out-of-date; and knowledge of current best evidence declining with time from graduation from medical college. EBM has become feasible for practicing clinicians due to: new strategies for appraising studies; availability of systematic reviews (summaries) of current best evidence; and information technology (computers with Internet access). In a resource-limited country such as Pakistan, an evidence-based approach can be cost-effective by reducing clinical practices that have no proven benefit. Commonly perceived obstacles to EBM include limited access to computers, the Internet and online resources. Reliable resources of EBM are available (such as The Cochrane Database of Systematic Reviews http://www.cochrane.org) although many of these require paid subscriptions. Another difficulty is the issue of applicability of data from other countries to patients in our setting with different socio-economic factors. Other barriers to EBM in developing countries include: inexperience in small-group learning, limited time to attend workshops, and the lack of role models for practicing EBM. We have also tried to address the common fallacies related to EBM in the hope of greater use of these skills by busy clinicians as well as academic researchers. PMID:18062522

    The joint JAXA/NASA ASTRO-H mission is the sixth X-ray mission initiated by the Institute of Space and Astronautical Science (ISAS). ASTRO-H allows a combination of wide band X-ray spectroscopy (5-80 keV) provided by multilayer coating, focusing hard X-ray mirrors and hard X-ray imaging detectors, and high energy-resolution soft X-ray spectroscopy (0.3-12 keV) provided by thin-foil X-ray optics and a micro-calorimeter array. The mission will also carry a X-ray CCD camera as a focal plane detector for a soft X-ray telescope (0.4-12 keV) and a non-focusing soft gamma-ray detector (40-600 keV). ASTRO-H is expected to provide breakthrough results in the studies of the large-scale structure of the Universe and its evolution, the behaviour of matter in the strong gravitational field regime, providing time-resolved spectra from material approaching the event horizon of a black hole, the physical conditions in sites of cosmic-ray acceleration, and the distribution of dark matter in galaxy clusters at different redshifts. ASTRO-H will be launched into low-Earth orbit from the Tanegashima Space Center, Japan, by a JAXA H-IIA rocket.

    International Nuclear Information System (INIS)

    The events on September 11, 2001 were unpredictable and tragic, however it is not inconceivable that a similar terrorist event could occur again, this time involving radiologic or nuclear material. In order to prepare for this American Society for Therapeutic Radiology and Oncology (ASTRO) convened a task force. Initially the task force worked with the American College of Radiology (ACR)and the American Society of Physicists in Medicine (AAPM)to publish a PRIMER entitled 'Disaster Preparedness for Radiology Professionals'. The PRIMER serve as a quick reference in the event of a radiation disaster and is available on the ASTRO Web site (www.astro.org). The task force has also developed a detailed and extensive training program, in partnership with the U.S. Department of Energy's Radiation Emergency Assistance Center/Training Site (REAC/TS) in Oak Ridge (TN), that will equip radiation oncologists with the necessary expertise to train hospital radiation oncology departments and other healthcare personnel who are responsible for implementing and carrying out hospital planning for disasters involving radioactive materials. This presentation will outline the effort ASTRO has been involved with since September 11, 2001 to prepare the professional community it represent in the event of a radiation/nuclear disaster

    Various interventions are used in clinical practice to address insecure or disorganized attachment patterns and attachment disorders. The most common of these are parenting interventions, but not all have a robust empirical evidence base. We undertook a systematic review of randomized trials comparing a parenting intervention with a control, where these used a validated attachment instrument, in order to evaluate the clinical and cost-effectiveness of interventions aiming to improve attachment in children with severe attachment problems (mean age <13 years). This article aims to inform clinicians about the parenting interventions included in our systematic review that were clinically effective in promoting secure attachment. For completeness, we also briefly discuss other interventions without randomized controlled trial evidence, identified in Patient Public Involvement workshops and expert groups at the point our review was completed as being used or recommended. We outline the key implications of our findings for clinical practice and future research. PMID:27583298

    2011-03-01

    Full Text Available Evidence based library and information practice (EBLIP is a strategy to bridge research and practice. Generally EBLIP is seen as a movement to encourage and give practitioners the means to incorporate research into their practice, where it previously may have been lacking. The widely accepted definition of EBLIP (Booth, 2000 stresses three aspects that contribute to a practice that is evidence based: 1 "the best available evidence;" 2 "moderated by user needs and preferences;" 3 "applied to improve the quality of professional judgements." The area that the EBLIP movement has focused on is how to create and understand the best available research evidence. CE courses, critical appraisal checklists, and many articles have been written to address a need for librarian education in this area, and it seems that strides have been made.But very little in the EBLIP literature talks about how we make professional judgements, or moderate evidence based on our user needs and preferences. Likewise, how do we make good evidence based decisions when our evidence base is weak. These things seem to be elements we just take for granted or can’t translate into words. It is in keeping with tacit knowledge that librarians just seem to have or acquire skills with education and on the job experience. Tacit knowledge is "knowledge that is not easily articulated, and frequently involves knowledge of how to do things. We can infer its existence only by observing behaviour and determining that this sort of knowledge is a precondition for effective performance" (Patel, Arocha, & Kaufman, 1999, p.78. It is something that is difficult to translate into an article or guideline for how we work. I think of this area as the "art" of evidence based practice. And the art is crucial to being an evidence based practitioner.Science = systematized knowledge, explicit research, methodological examination, investigation, dataArt = professional knowledge of your craft, intuition

  16. ASTRO's 2007 Core Physics Curriculum for Radiation Oncology Residents

    International Nuclear Information System (INIS)

    In 2004, American Society for Therapeutic Radiology and Oncology (ASTRO) published a curriculum for physics education. The document described a 54-hour course. In 2006, the committee reconvened to update the curriculum. The committee is composed of physicists and physicians from various residency program teaching institutions. Simultaneously, members have associations with American Association of Physicists in Medicine, ASTRO, Association of Residents in Radiation Oncology, American Board of Radiology, and American College of Radiology. Representatives from the latter two organizations are key to provide feedback between the examining organizations and ASTRO. Subjects are based on Accreditation Council for Graduate Medical Education requirements (particles and hyperthermia), whereas the majority of subjects and appropriated hours/subject were developed by consensus. The new curriculum is 55 hours, containing new subjects, redistribution of subjects with updates, and reorganization of core topics. For each subject, learning objectives are provided, and for each lecture hour, a detailed outline of material to be covered is provided. Some changes include a decrease in basic radiologic physics, addition of informatics as a subject, increase in intensity-modulated radiotherapy, and migration of some brachytherapy hours to radiopharmaceuticals. The new curriculum was approved by the ASTRO board in late 2006. It is hoped that physicists will adopt the curriculum for structuring their didactic teaching program, and simultaneously, American Board of Radiology, for its written examination. American College of Radiology uses the ASTRO curriculum for their training examination topics. In addition to the curriculum, the committee added suggested references, a glossary, and a condensed version of lectures for a Postgraduate Year 2 resident physics orientation. To ensure continued commitment to a current and relevant curriculum, subject matter will be updated again in 2 years

  18. The ground calibration of X-ray CCD cameras (XIS) with front-illuminated chips onboard Astro-E2

    International Nuclear Information System (INIS)

    We report on the results of the ground calibration of Astro-E2 XIS with front-illuminated (FI) chips. The sensors have basically the same performance as that of Astro-E XIS. However, there are some improved points: (1) A 55Fe radio isotope is equipped on the door and (2) the capability for charge injection (CI) has been added. We measured the gain, energy resolution, and quantum efficiency (QE) of the FI sensors as a function of energy by using characteristic X-rays for each sensor. An energy resolution of 130 eV at 5.9 keV in FWHM and a QE of 52% at 8.6 keV are achieved. After XIS is launched, the charge transfer inefficiency (CTI) will increase due to radiation damage by cosmic rays. Then XIS is equipped with the CI capability to calibrate and compensate for the increase in CTI. We estimate the time variability in the amount of the injected charge

    Sir Arthur Conan Doyle, the creator of the fictional detective Sherlock Holmes, studied medicine at the University of Edinburgh between 1876 and 1881 under Doctor Joseph Bell who emphasised in his teaching the importance of observation, deduction and evidence. Sherlock Holmes was modelled on Joseph Bell. The modern notions of Evidence Based Medicine (EBM) are not new. A very brief indication of some of the history of EBM is presented including a discussion of the important and usually overlooked contribution of statisticians to the Popperian philosophy of EBM.

    Full Text Available Abstract Background Infertility is defined as inability of a couple to conceive naturally after one year of regular unprotected sexual intercourse. It remains a major clinical and social problem, affecting perhaps one couple in six. Evaluation usually starts after 12 months; however it may be indicated earlier. The most common causes of infertility are: male factor such as sperm abnormalities, female factor such as ovulation dysfunction and tubal pathology, combined male and female factors and unexplained infertility. Objectives The aim of this study is to provide the healthcare professionals an evidence-based management protocol for infertile couples away from medical information overload. Methods A comprehensive review where the literature was searched for "Management of infertility and/or infertile couples" at library website of University of Bristol (MetaLib by using a cross-search of different medical databases besides the relevant printed medical journals and periodicals. Guidelines and recommendations were retrieved from the best evidence reviews such as that from the American College of Obstetricians and Gynaecologists (ACOG, American Society for Reproductive Medicine (ASRM, Canadian Fertility and Andrology Society (CFAS, and Royal College of Obstetricians and Gynaecologists (RCOG. Results A simple guide for the clinicians to manage the infertile couples. Conclusions The study deploys a new strategy to translate the research findings and evidence-base recommendations into a simplified focused guide to be applied on routine daily practice. It is an approach to disseminate the recommended medical care for infertile couple to the practicing clinicians.

    Acupressure is a traditional Chinese medicine approach to disease prevention and treatment that may be operated by nurses independently. Therefore, acupressure is being increasingly applied in clinical nursing practice and research. Recently, the implementation of evidence-based nursing (EBN) in clinical practice has been encouraged to promote nursing quality. Evidence-based nursing is a method-ology and process of implementation that applies the best-available evidence to clinical practice, which is acquired through the use of empirical nursing research. Therefore, in this paper, we address the topic of acupressure within the context of empirical nursing practice. We first introduce the current status of acupressure research and provide the locations of common acupoints in order to guide future empirical nursing research and to help nurses use these acupoints in clinical practice. Finally, we describe the steps that are necessary to apply the current empirical information on acupressure as well as provide suggestions to promote safety and efficacy in order to guide nurses in the accurate application of acupressure in nursing practice.

  2. Radiation oncology. An evidence-based approach

    International Nuclear Information System (INIS)

    Radiation Oncology: An Evidence-Based Approach (ROEBA) is a reference book designed to enable radiation oncologists, including those in training, to make diagnostic and treatment decisions on the basis of the best available scientific evidence. Ease of use is ensured by a structured, reader-friendly format that offers rapid access to evidence-based recommendations. ROEBA's orientation is entirely practical, in that the focus is solely on diagnostic/staging and treatment issues. Detailed diagnostic and therapeutic guidelines are provided for multidisciplinary cancer management as well as radiation therapy techniques. The evidence underlying each recommendation is clearly and concisely explained, and the strength of the recommendations and evidence is systemically graded. Furthermore, diagnostic and treatment algorithms are provided for commonly diagnosed cancers, including non-small-cell lung cancer, small-cell lung cancer, most gastrointestinal and genitourinary tumors, and certain head and neck cancers. This ground-breaking text on radiation oncology is an essential tool for physicians in their daily clinical practice. (orig.)

    Full Text Available Hypertension is an important worldwide public -health challenge with high mortality and disability. Due to the limitations and concerns with current available hypertension treatments, many hypertensive patients, especially in Asia, have turned to Chinese medicine (CM. Although hypertension is not a CM term, physicians who practice CM in China attempt to treat the disease using CM principles. A variety of approaches for treating hypertension have been taken in CM. For seeking the best evidence of CM in making decisions for hypertensive patients, a number of clinical studies have been conducted in China, which has paved the evidence-based way. After literature searching and analyzing, it appeared that CM was effective for hypertension in clinical use, such as Chinese herbal medicine, acupuncture, moxibustion, cupping, qigong, and Tai Chi. However, due to the poor quality of primary studies, clinical evidence is still weak. The potential benefits and safety of CM for hypertension still need to be confirmed in the future with well-designed RCTs of more persuasive primary endpoints and high-quality SRs. Evidence-based Chinese medicine for hypertension still has a long way to go.

  4. Radiographers' preconditions for evidence-based radiography

    International Nuclear Information System (INIS)

    Evidence-based practice (EBP) is essential in today's health care, but its establishment requires several preconditions from individuals and organizations (e.g. knowledge, understanding, attitudes, abilities, self-confidence, support, and resources). Previous studies suggest that radiographers do generate and use evidence in their work, but evidence-based radiography (EBR) is not yet used routinely as established practice, especially in terms of research utilization. This paper aims to describe radiographers' preconditions for EBR, and their participation in research activities. Main focus is on research utilization. Using an electronic questionnaire developed for this study, a survey was conducted: data collected from Finnish radiographers and radiotherapists (N = 438) were analysed both statistically and qualitatively. The final response rate was 39%. The results suggest radiographers' preconditions for EBR to consist of knowledge of research, significance of research activities, research-orientated way of working, and support. In addition, adequate resourcing is essential. Reading scientific journals, participation in research activities, a higher degree of education, and senior post seem to be significant promoters of EBR and research utilization. The results support the notion that EBR, and especially research utilization, are not yet well-established in Finland, and radiographers' viewpoints concerning the role and significance of research evidence and research activities still seem to vary.

    Full Text Available Abstract Evidence-based medicine (EBM is a fashionable and an extremely hot topic for clinicians, patients and the health service planners. Evidence-based cytology (EBC is an offshoot of EBM. The EBC is concerned with generating a reproducible, high quality and clinically relevant test result in the field of cytology. This is a rapidly evolving area with high practical importance. EBC is based entirely on research data. The various professional bodies on cytology design and recommend guidelines on the basis of evidences. Once the guideline is implemented and practiced then the experiences of the practicing cytopathologists may be used as a feed back to alter the existing guideline. The various facets of EBC are sampling and specimen adequacy, morphological identification and computer based expert system, integrated reporting, identification of the controversial areas and high quality researches for evidences. It is the duty of the individuals and institutions to practice EBC for better diagnosis and management of the patients. In this present paper, the various aspects of EBC have been discussed.

  6. Achievements and Limitations of Evidence-Based Medicine.

    Sheridan, Desmond J; Julian, Desmond G

    2016-07-12

    Evidence-based medicine (EBM) has a long history, but was revived in the early 1990s by a campaign mounted by a movement that took its name. The EBM movement focused attention on the need for greater objectivity in medical decision-making and led to the Cochrane Collaboration, which provides reviews of evidence on the basis of comparative research. Important limitations of EBM's effect on medicine have also emerged. Failure to acknowledge the limitations of clinical trials and systematic reviews has limited their applicability to individual patients' circumstances. An almost exclusive focus on drugs and devices has left vast areas of health care in an evidence vacuum. An overdependence on commissions for its research may have limited its independence in selecting what it investigates. EBM needs to widen its scope beyond drugs and devices to address many areas that often lack evidence at present, notably, health policy, management, and reforms. PMID:27386775

    2016-01-01

    Evidence-based practice (EBP) is an approach used in numerous professions that focuses attention on evidence quality in decision making and action. We review research on EBP implementation, identifying critical underlying psychological factors facilitating and impeding its use. In describing EBP and the forms of evidence it employs, we highlight the challenges individuals face in appraising evidence quality, particularly that of their personal experience. We next describe critical EBP competencies and the challenges underlying their acquisition: foundational competencies of critical thinking and domain knowledge, and functional competencies such as question formulation, evidence search and appraisal, and outcome evaluation. We then review research on EBP implementation across diverse fields from medicine to management and organize findings around three key contributors to EBP: practitioner ability, motivation, and opportunity to practice (AMO). Throughout, important links between psychology and EBP are highlighted, along with the contributions psychological research can make to further EBP development and implementation. PMID:26361048

    Full Text Available Objective To evaluate the therapeutic efficacy and side effects of various treatment for sleep disorders in order to provide the best therapeutic regimen for the evidence-based treatment of sleep disorders. Methods Sleep disorder, insomnia, restless legs syndrome or RLS, obstructive sleep apnea or OSA, narcolepsy, REM behaviour disorder or RBD, treatment or therapy were used as retrieval words. Cochrane Library, MEDLINE, ScienceDirect were used for retrieval, and manual searching was also used. Related clinical guidelines, systematic reviews, randomized controlled clinical trials, retrospective case analysis, case-observation studies and reviews were collected and evaluated by Jadad Scale. Results Forty related articles were selected as following: 6 clinical guidelines, 12 systematic reviews, 5 randomized controlled trials, 2 retrospective case analysis, 1 case-observation study and 14 reviews. Thirty-three were of high quality, while 7 were of low quality with score. According to the evaluation of therapeutic efficacy and side effects of various therapies, it is suggested as following: 1 insomnia is the most common in sleep disorders; the treatment methods of insomnia mainly include drug therapy and cognitive behavioral treatment (CBT; the two kinds of therapy have their own advantages and disadvantages, and the combination therapy of drugs and CBT is the best treatment plan. 2 The first-line treatment of primary RLS is dopamine agonists and anti-seizure drugs; however, the treatment of secondary RLS is mainly etiologic treatment. 3 The main treatments of OSAS are nasal continuous positive airway pressure (nCPAP, oral orthotics and surgery, and nCPAP is the first-line treatments. 4 The medication of narcolepsy is mainly modafinil, hydroxy butyric acid sodium and antidepressants, and the specific choosingshould accord to clinical classifications. 5 The main treatments of RBD include general treatments such as avoiding triggers, insuring the

    2016-06-01

    This issue of the Clinical Journal of Oncology Nursing (CJON) will be the final time that you will see the Evidence-Based Practice (EBP) feature column. Why? Because we have seen oncology nursing evolve in the past 20 years and EBP is everywhere! We use it in our clinics and hospital units, incorporate it into decisions about symptom management, and use evidence to develop survivorship guidelines. We discuss EBP in journal clubs and use applications on mobile devices to find the best interventions for our patients. We have oncology nurses sitting on committees to develop guidelines based on the best evidence and expert opinion. We have come a long way and it is our belief that EBP is included in almost every article in CJON and, therefore, a need no longer exists for an individual column about EBP.

    2014-01-01

    Astronomy and astrophysics are witnessing dramatic increases in data volume as detectors, telescopes and computers become ever more powerful. During the last decade, sky surveys across the electromagnetic spectrum have collected hundreds of terabytes of astronomical data for hundreds of millions of sources. Over the next decade, the data volume will enter the petabyte domain, and provide accurate measurements for billions of sources. Astronomy and physics students are not traditionally trained to handle such voluminous and complex data sets. In this paper we describe astroML; an initiative, based on Python and scikit-learn, to develop a compendium of machine learning tools designed to address the statistical needs of the next generation of students and astronomical surveys. We introduce astroML and present a number of example applications that are enabled by this package.

    The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX, Hill et al. 2012b) is a blind spectroscopic survey to map the evolution of dark energy using Lyman-alpha emitting galaxies at redshifts 1.9management. It can be used to create various web interfaces for data access and quality control. Astro-WISE allows us to reduce the data from all the IFUs in parallel on a compute cluster. This cluster allows us to reduce the observed data in quasi real time and still have excess capacity for rerunning parts of the reduction. Finally, the Astro-WISE interface will be used to provide access to reduced data products to the general community.

    2015-09-01

    There has been a paradigm shift in medicine away from tradition, anecdote and theoretical reasoning from the basic sciences towards evidence-based medicine (EBM). In palliative care however, statistically significant benefits may be marginal and may not be related to clinical meaningfulness. The typical treatment vs. placebo comparison necessitated by 'gold standard' randomised controlled trials (RCTs) is not necessarily applicable. The complex multimorbidity of end of life care involves considerations of the patient's physical, psychological, social and spiritual needs. In addition, the field of palliative care covers a heterogeneous group of chronic and incurable diseases no longer limited to cancer. Adequate sample sizes can be difficult to achieve, reducing the power of studies and high attrition rates can result in inadequate follow up periods. This review uses examples of the management of cancer-related fatigue and death rattle (noisy breathing) to demonstrate the current state of EBM in palliative care. The future of EBM in palliative care needs to be as diverse as the patients who ultimately derive benefit. Non-RCT methodologies of equivalent quality, validity and size conducted by collaborative research networks using a 'mixed methods approach' are likely to pose the correct clinical questions and derive evidence-based yet clinically relevant outcomes.

    2007-03-01

    With the dramatic increase in the amount of scientific information available about oral health, an evidence-based approach to oral health care and the practice of dentistry is necessary. There is a need to summarize, critique, and disseminate scientific evidence and to translate the evidence into a practical format that is used easily by dentists. The evidence-based clinical recommendations in this report were developed by an expert panel established by the American Dental Association Council on Scientific Affairs that evaluated the collective body of scientific evidence on the effectiveness of professionally applied topical fluoride for caries prevention. The recommendations are intended to assist dentists in clinical decision making. MEDLINE and the Cochrane Library were searched for systematic reviews and clinical studies of professionally applied topical fluoride-including gel, foam, and varnish-through October 2005. Panelists were selected on the basis of their expertise in the relevant subject matter. The recommendations are stratified by age groups and caries risk and indicate that periodic fluoride treatments should be considered for both children and adults who are at moderate or high risk of developing caries. Included in the clinical recommendations is a summary table that can be used as a chairside resource. The dentist, knowing the patient's health history and vulnerability to oral disease, is in the best position to make treatment decisions in the interest of each patient. These clinical recommendations must be balanced with the practitioner's professional expertise and the individual patient's preferences. PMID:17389574

  2. ASTRO's core physics curriculum for radiation oncology residents

    International Nuclear Information System (INIS)

    In 2002, the Radiation Physics Committee of the American Society of Therapeutic Radiology and Oncology (ASTRO) appointed an Ad-hoc Committee on Physics Teaching to Medical Residents. The main initiative of the committee was to develop a core curriculum for physics education. Prior publications that have analyzed physics teaching have pointed to wide discrepancies among teaching programs. The committee was composed of physicists or physicians from various residency program based institutions. Simultaneously, members had associations with the American Association of Physicists in Medicine (AAPM), ASTRO, Association of Residents in Radiation Oncology (ARRO), American Board of Radiology (ABR), and the American College of Radiology (ACR). The latter two organizations' representatives were on the physics examination committees, as one of the main agendas was to provide a feedback loop between the examining organizations and ASTRO. The document resulted in a recommended 54-h course. Some of the subjects were based on American College of Graduate Medical Education (ACGME) requirements (particles, hyperthermia), whereas the majority of the subjects along with the appropriated hours per subject were devised and agreed upon by the committee. For each subject there are learning objectives and for each hour there is a detailed outline of material to be covered. Some of the required subjects/h are being taught in most institutions (i.e., Radiation Measurement and Calibration for 4 h), whereas some may be new subjects (4 h of Imaging for Radiation Oncology). The curriculum was completed and approved by the ASTRO Board in late 2003 and is slated for dissemination to the community in 2004. It is our hope that teaching physicists will adopt the recommended curriculum for their classes, and simultaneously that the ABR for its written physics examination and the ACR for its training examination will use the recommended curriculum as the basis for subject matter and depth of

    Full Text Available Background:   Patellofemoral pain syndrome (PFPS is defined as pain surrounding the patella when sitting with bent knees for prolonged periods of time or when performing activities like ascending or descending stairs, squatting or   athletic activities. Patella dislocation is not included in PFPS.     Purpose:   This review analyzes the evidence based conservative management of PFPS.   Methods:   A Cochrane Library search related to PFPS was performed until 18 January 2014. The key words were: patellofemoral pain syndrome. Eight papers were found, of which three were reviewed because they were focused   on the topic of the article. We also searched the PubMed using the following keywords: evidence based conservative   management of patellofemoral pain syndrome. Twelve articles were found, of which seven were reviewed because   they were focused on the topic of the article. Overall ten articles were analyzed.     Results:   Different treatments can be tried for PFPS, including pharmacotherapy, therapeutic ultrasound, exercise therapy, and taping and braces.     Conclusions:   Non-steroidal anti-inflammatory drugs (NSAIDs may reduce pain in the short term, but pain does not improve after three months. Therapeutic ultrasound appears not to have a clinically important effect on pain relief for   patients with PFPS. The evidence that exercise therapy is more effective in treating PFPS than no exercise is limited   with respect to pain reduction, and conflicting with respect to functional improvement. No significant difference has   been found between taping and non-taping. The role of knee braces is still controversial. More well-designed studies are needed.

    The joint JAXA/NASA ASTRO-H mission is the sixth in a series of highly successful X-ray missions developed by the Institute of Space and Astronautical Science (ISAS), with a planned launch in 2015. The ASTRO-H mission is equipped with a suite of sensitive instruments with the highest energy resolution ever achieved at E > 3 keV and a wide energy range spanning four decades in energy from soft X-rays to gamma-rays. The simultaneous broad band pass, coupled with the high spectral resolution of Delta E < 7 eV of the micro-calorimeter, will enable a wide variety of important science themes to be pursued. ASTRO-H is expected to provide breakthrough results in scientific areas as diverse as the large-scale structure of the Universe and its evolution, the behavior of matter in the gravitational strong field regime, the physical conditions in sites of cosmic-ray acceleration, and the distribution of dark matter in galaxy clusters at different redshifts.

  9. Magnitude calibration of a fixed head star tracker using Astro-1 flight data

    Rakoczy, John M.; West, Mark E.

    1992-01-01

    The Astro-1 UV astronomy mission was hampered by the failures of the automatic star acquisition procedure. The acquisition procedure depended on the Instrument Pointing Subsystem's Fixed Head Star Trackers (FHST) to acquire, track and identify guidestars of known visual magnitude. During the Astro-1 mission it was suspected that the star magnitudes measured by the FHST were much lower than predicted. A postflight investigation of the Astro-1 flight data confirmed and quantified this suspicion. Star magnitude calibration curves computed from the flight data depict the variance from the preflight calibration curves. These results are helping engineers to plan improvements to the acquisition procedure for the upcoming Astro-2 mission.

    Full Text Available Cancer Research UK has developed PROforma, a formal language for modelling clinical processes, along with associated tools for creating decision support, care planning, clinical workflow management and other applications. The PROforma method has been evaluated in a variety of settings: in primary health care (prescribing, referral of suspected cancer patients, genetic risk assessment and in specialist care of patients with breast cancer, leukaemia, HIV infection and other conditions. About nine years of experience have been gained with PROforma technologies. Seven trials of decision support applications have been published or are in preparation. Each of these has shown significant positive effects on a variety of measures of quality and/or outcomes of care. This paper reviews the evidence base for the clinical effectiveness of these PROforma applications, and previews the CREDO project _a multi-centre trial of a complex PROforma application for supporting integrated breast cancer care across primary and secondary care settings.

    2012-01-01

    The debate around the role of the work at personal computer as cause of De Quervain's Tenosynovitis was developed partially, without considering multidisciplinary available data. A systematic review of the literature, using an evidence-based approach, was performed. In disorders associated with the use of VDU, we must distinguish those at the upper limbs and among them those related to an overload. Experimental studies on the occurrence of De Quervain's Tenosynovitis are quite limited, as well as clinically are quite difficult to prove the professional etiology, considering the interference due to other activities of daily living or to the biological susceptibility (i.e. anatomical variability, sex, age, exercise). At present there is no evidence of any connection between De Quervain syndrome and time of use of the personal computer or keyboard, limited evidence of correlation is found with time using a mouse. No data are available regarding the use exclusively or predominantly for personal laptops or mobile "smart phone". PMID:23405595

    evidence on the effectiveness of road safety interventions in reducing road traffic collisions, injuries and deaths. Methodology: All literature reviews published in scientific journals that assessed the effectiveness of one or more road safety interventions and whose outcome measure was road traffic crashes, injuries or fatalities were included. An exhaustive search was performed in scientific literature databases. The interventions were classified according to the evidence of their effectiveness in reducing road traffic injuries (effective interventions, insufficient evidence of effectiveness, ineffective interventions following the structure of the Haddon matrix. Results: Fifty-four reviews were included. Effective interventions were found before, during and after the collision, and across all factors: a the individual: the graduated licensing system (31% road traffic injury reduction; b the vehicle: electronic stability control system (2 to 41% reduction; c the infrastructure: area-wide traffic calming (0 to 20%, and d the social environment: speed cameras (7 to 30%. Certain road safety interventions are ineffective, mostly road safety education, and others require further investigation. Conclusion: The most successful interventions are those that reduce or eliminate the hazard and do not depend on changes in road users' behavior or on their knowledge of road safety issues. Interventions based exclusively on education are ineffective in reducing road traffic injuries.

    2004-01-01

    Evidence-based medicine (EBM) integrates the best available external evidence in the care of individual patients with the individual clinical expertise and the patient preferences. This method has been designed for use in daily clinical practice. We describe the rationale for EBM and its principles and application in this article. EBM enables gastroenterologists to update the knowledge required to provide patients with high quality medical care. EBM requires four steps: a) formulating a clinical question arising from a doubt concerning a patient; b) conducting an efficient literature search to answer this question; c) critically appraising this evidence using explicit methods to selected articles to determine the validity of their design and the clinical relevance of their results; and d) applying these results to the patient (taking into account their values and preferences and personal and social circumstances). In this paper, we explain the principles and basic concepts of EBM and their application to gastroenterology and we provide an extensive compilation of internet databases of valid information relevant to gastroenterologists. We also provide a selection of useful tools for self-directed learning of critical appraisal skills.

    2011-06-01

    Full Text Available Evidence-based interactive management of change means hands-on experience of modified work processes, given evidence of change. For this kind of pro-active organizational development support we use an organisational process memory and a communication-based representation technique for role-specific and task-oriented process execution. Both are effective means for organizations becoming agile through interactively modelling the business at the process level and re-constructing or re-arranging process representations according to various needs. The tool allows experiencing role-specific workflows, as the communication-based refinement of work models allows for executable process specifications. When presenting the interactive processes to individuals involved in the business processes, changes can be explored interactively in a context-sensitive way before re-implementing business processes and information systems. The tool is based on a service-oriented architecture and a flexible representation scheme comprising the exchange of message between actors, business objects and actors (roles. The interactive execution of workflows does not only enable the individual reorganization of work but also changes at the level of the entire organization due to the represented interactions.

    Full Text Available I love food. I love cooking, baking, testing, and eating. I read about food preparation, food facts, and food service. Over the years I’ve developed my fair share of knowledge about cooking and I’m a decent cook, but I’m no chef. I guess I’m what you’d call a “foodie”. However, I have the good fortune to have a friend who is a chef and owns one of the best, and certainly the most innovative, restaurants in town. During this summer I hosted a cooking class in my home for my family with my chef friend as instructor. The Tex-Mex barbecue theme was a big hit (you can contact me for recipes, if you like, but much more fascinating was the explanation of the science behind the cooking. It turns out that there is a term for this: molecular gastronomy. Another term, and hence the genesis of my “Eureka!” moment of the summer, is evidence based cooking. Good cooking is not just following a recipe (not all of which are evidence based but at its best is the culmination of heaps of tested information regarding why and how chemical and environmental factors work together to result in a gastronomical delight. For example, will brining or marinating a pork chop make it moister? And, if brining, what temperature should the water be, how long should it soak, and how much salt is needed? Why does pounding meat increase its tenderness? What will keep guacamole from browning better – the pit or lime juice? What does baking soda do in a chocolate cake? Eggs or no eggs in fresh pasta? Like most librarians, I tend not to take information at face value. I want to know where information comes from and whether or not it is valid, based on specific factors. I’ve come to notice that evidence based, or evidence informed, practice is everywhere and has a tremendous impact on our lives. Why do you rotate the tires on your car? Evidence shows that the front tires wear more quickly (think about all those 3-pointturns, the braking, etc and therefore

    or blocks", "medial nerve blocks" and "low back pain". The search was performed in the Trip Database, SUMSearch, National Guidelines Clearinghouse, Cochrane and centers drawing up clinical practice guidelines. Clinical practice guidelines with levels of evidence, systematic reviews, meta-analyses and cross references among publications reviewed in Spanish or English from 1979 to 2009 were accepted. Results: Five clinical practice guidelines and nine systematic reviews were selected. Analysis of these articles indicated that intradiscal injections cannot be recommended in the treatment of chronic low back pain. The evidence on lumbar, cervical and thoracic medial branch injection in the treatment of lumbar, cervical and dorsal back pain is moderate for short- and long-term improvement. The evidence for sacroiliac joint injection is limited. Cervical interlaminar epidural injection provides significant and prolonged relief in chronic intractable cervical pain. There is level II-2 evidence for lumbar interlaminar epidural steroid injection, without fluoroscopy, in providing short-term relief and level II evidence for long-term relief. Transforaminal epidural steroid injection is effective in postlaminectomy syndrome (level IV evidence. There is moderate evidence for short- and long-term improvement in cervical radicular pain. Transforaminal epidural injection provides significant relief in chronic low back pain and radicular lumbar pain with level II-1 evidence for short-term improvement and level II-2 evidence for long-term improvement, with strong level 1C recommendation. Caudal epidural steroid injection was effective in producing short-term improvement (level II evidence as well as long-term relief (level III evidence. Pain relief was achieved in postlaminectomy low back pain and spinal canal stenosis (level IV evidence. Conclusions: There are differences in the effectiveness, level of evidence and grade of recommendation for steroid use, associated or not with

    OBJECTIVE: To formulate an evidence-based treatment for one patient with acute spinal cord injury and summarize evidence for evaluating acute spinal cord injury treatment. METHODS: Studies related to the treatment for acute spinal cord injury were identified via a search of National Guideline Clearinghouse (NGC, 2000-11), the Cochrane Library (Issue 1, 2011), TRIP Database (2000-11), and PubMed (1966-2011). Treatment strategies were formulated according to three basic principles: best evidence, doctor's professional experience, and wishes of the patient. RESULTS: A total of 34 articles were selected, including 1 NGC guideline, 22 systematic reviews, and 11 randomized controlled trials. Based on our review, we arrived at the following recommendations: no clinical evidence exists definitively to recommend the use of any of neuroprotective pharmaceuticals; surgery should be undertaken early; mechanical compression devices and low-molecular weight heparin should be employed to prevent thrombosis; respiratory muscle training is beneficial for pulmonary function and quality of life; and functional electrical stimulation and acupuncture can promote functional recovery. The patient accordingly underwent surgery 6 hours after trauma without receiving any neuroprotective pharmaceuticals; low-molecular weight heparin and intermittent pneumatic compression were applied to prevent thrombosis. He also underwent respiratory muscle training daily for 8 weeks and received functional electrical stimulation for 15 minutes and acupuncture for 30 minutes every day. After follow-up for 3 months, the above therapeutic regimen was confirmed efficacious for acute spinal cord injury.CONCLUSION: Evidence-based medicine provides an individualized treatment protocol for acute spinal cord injury, which can significantly improve the therapeutic effect and prognosis.

    In the past decade, increased emphasis has been placed on identifying treatments for childhood disorders that are supported by empirical evidence of their effectiveness. This process was spearheaded by an American Psychological Association division 12 task force that identified evidence-based treatments--mostly for disorders of adulthood. Because of the publication of the task force results, other studies have been published that contribute to the knowledge base of evidence-based treatment, and these studies are briefly reviewed. Across evidence-based treatments, common features of effective treatments, such as parent involvement, use of a treatment manual, and the emphasis on generalization of treatment effects to natural settings, are also identified and reviewed.Introduction PMID:11914169

    Full Text Available Objective To evaluate the effectiveness of the treatments for sleep disorders in neurodegenerative diseases so as to provide the best therapeutic regimens for the evidence-based treatment. Methods Search PubMed, MEDLINE, Cochrane Library, Wanfang Data and China National Knowledge Infrastructure (CNKI databases with "sleep disorder or sleep disturbance", "neurodegenerative diseases", "Parkinson's disease or PD", "Alzheimer's disease or AD", "multiple system atrophy or MSA" as retrieval words. The quality of the articles were evaluated with Jadad Scale. Results A total of 35 articles, including 2 systematic reviews, 5 randomized controlled trials, 13 clinical controlled trials, 13 case series and 2 epidemiological investigation studies were included for evaluation, 13 of which were high grade and 22 were low grade articles. Clinical evidences showed that: 1 advice on sleep hygiene, careful use of dopaminergic drugs and hypnotic sedative agents should be considered for PD. Bright light therapy (BLT may improve circadian rhythm sleep disorders and clonazepam may be effective for rapid eye movement sleep behavior disorder (RBD. However, to date, very few controlled studies are available to make a recommendation for the management of sleep disorders in PD; 2 treatments for sleep disorders in AD include drug therapy (e.g. melatonin, acetylcholinesterase inhibitors, antipsychotic drugs, antidepressants and non-drug therapy (e.g. BLT, behavior therapy, but very limited evidence shows the effectiveness of these treatments; 3 the first line treatment for sleep-related breathing disorder in MSA is nasal continuous positive airway pressure (nCPAP, and clonazepam is effective for RBD in MSA; 4 there is rare evidence related to the treatment of sleep disorders in dementia with Lewy body (DLB and amyotrophic lateral sclerosis (ALS. Conclusion Evidence-based medicine can provide the best clinical evidence on sleep disorders' treatment in neurodegenerative

    2015-08-01

    Full Text Available Introduction and objectivesIt is has been widely accepted that assessment of learning is a critical component of education and that assessment drives/guides student learning through shaping study habits and student approaches to learning. However, although most academics would agree that assessment is a critical aspect of their roles as teachers it is often an aspect of teaching that is regarded more as an additional task rather than an integral component of the teaching/learning continuum. An additional impediment to high quality assessment is the non-evidence based-approach to the decision making process. The overall aim of this project was to improve the quality of assessment in Biochemistry and Molecular Biology undergraduate education by promoting high quality assessment.Materials and methodsTo do this we developed and trialled an audit tool for mapping assessment practices. The audit tool was designed to gather data on current assessment practices and identify areas of good practice in which assessment aligned with the learning objectives and areas in need of improvement. This evidence base will then be used to drive change in assessment.Results and conclusionsUsing the assessment mapping tool we have mapped the assessment regime in a Biochemistry and Molecular Biology major at Monash University. Criteria used included: assessment type, format, timing, assessors, provision of feedback, level of learning (Bloom’s, approaches taken to planning assessment. We have mapped assessment of content and the systematic development of higher order learning and skills progression throughout the program of study. The data has enabled us to examine the assessment at unit (course level as well as the vertical development across the major. This information is now being used to inform a review of the units and the major.

    Herbal medicine can be a valuable source of assistance for traditional medicine. There are a number of herbs that can be used in conjunction with modern medicine. Herbs can also be taken to aid recovery from serious diseases. Although one should never aim to treat diseases such as cardiovascular disease solely with herbal medicine, the value of herbs used in tandem with modern medicine cannot be ignored. Saffron has been reported to help lower cholesterol and keep cholesterol levels healthy. ...

  15. Cardiovascular Considerations in Antidepressant Therapy: An Evidence-Based Review

    Full Text Available There is a definite correlation between cardiovascular diseases and depressive disorders. Nevertheless, many aspects of this association have yet to be fully elucidated. Up to half of coronary artery disease patients are liable to suffer from some depressive symptoms, with approximately 20% receiving a diagnosis of major depressive disorders. Pharmacotherapy is a key factor in the management of major depression, not least in patients with chronic diseases who are likely to fail to show proper compliance and response to non-pharmacological interventions. Antidepressants are not deemed completely safe. Indeed, numerous side effects have been reported with the administration of antidepressants, among which cardiovascular adverse events are of paramount importance owing to their disabling and life-threatening nature. We aimed to re-examine some of the salient issues in antidepressant therapy vis-à-vis cardiovascular considerations, which should be taken into account when prescribing such medications.

    Full Text Available Neuromyelitis optica (NMO is an inflammatory disease of the central nervous system characterized by severe optic neuritis and transverse myelitis, usually with a relapsing course. Aquaporin-4 antibody is positive in a high percentage of NMO patients and it is directed against this water channel richly expressed on foot processes of astrocytes. Due to the severity of NMO attacks and the high risk for disability, treatment should be instituted as soon as the diagnosis is confirmed. There is increasing evidence that NMO patients respond differently from patients with multiple sclerosis (MS, and, therefore, treatments for MS may not be suitable for NMO. Acute NMO attacks usually are treated with high dose intravenous corticosteroid pulse and plasmapheresis. Maintenance therapy is also required to avoid further attacks and it is based on low-dose oral corticosteroids and non-specific immunosuppressant drugs, like azathioprine and mycophenolate mofetil. New therapy strategies using monoclonal antibodies like rituximab have been tested in NMO, with positive results in open label studies. However, there is no controlled randomized trial to confirm the safety and efficacy for the drugs currently used in NMO.

    Evidence-based practice has been demonstrated to improve quality of care, increase patients' satisfaction, and reduce the costs of medical care. Therefore, evidence-based practice is now central to the clinical decision-making process and to achieving better quality of care. Today, it is one of the important indicators of core competences for healthcare providers and accreditation for healthcare and educational systems. Further, evidence-based practice encourages in-school and continuous education programs to integrate evidence-based elements and concepts into curricula. Healthcare facilities and professional organizations proactively host campaigns and encourage healthcare providers to participate in evidence-based related training courses. However, the clinical evidence-based practice progress is slow. The general lack of a model for organizational follow-up may be a key factor associated with the slow adoption phenomenon. The authors provide a brief introduction to the evidence-based practice model, then described how it may be successfully translated through a staged process into the evidence-based practices of organizational cultures. This article may be used as a reference by healthcare facilities to promote evidence-based nursing practice. PMID:24096462

    Pain identification of cognitively impaired elderly is very challenging. This project aimed to identify best practices for pain assessment in nursing home residents with cognitive impairment and to establish a standardized pain assessment guide to optimize nursing practice and resident outcomes. The Iowa Model of Evidence-Based Practice to Promote Quality of Care guided the project's process. Phase I of the project analyzed data gained from chart reviews on current practices of pain assessment, and Phase II used the results of Phase I to develop, implement, and evaluate an evidence-based practice standard for nursing assessment of pain for cognitively impaired residents.

    Eating out of the home has been positively associated with body weight, obesity, and poor diet quality. While cooking at home has declined steadily over the last several decades, the benefits of home cooking have gained attention in recent years and many healthy cooking projects have emerged around the United States. The purpose of this study was to develop an evidence-based conceptual framework of healthy cooking behavior in relation to chronic disease prevention. A systematic review of the literature was undertaken using broad search terms. Studies analyzing the impact of cooking behaviors across a range of disciplines were included. Experts in the field reviewed the resulting constructs in a small focus group. The model was developed from the extant literature on the subject with 59 studies informing 5 individual constructs (frequency, techniques and methods, minimal usage, flavoring, and ingredient additions/replacements), further defined by a series of individual behaviors. Face validity of these constructs was supported by the focus group. A validated conceptual model is a significant step toward better understanding the relationship between cooking, disease and disease prevention and may serve as a base for future assessment tools and curricula.

    Full Text Available Cardiovascular diseases are now considered to be one of the major causes of mortality in the developed and developing world. With the advent of better diagnostic procedures and therapeutic strategies their management has become more efficient, yet the role of herbal and plant remedies is paramount in the developing and remote areas of the world. Phytotherapy or therapeutics using plants and herb based compounds or crude drugs are an indispensable part of Complementary and Alternative Medicine (CAM. The benefits of most of these plants are controversial as their toxicology and pharmacological activities are not well studied and documented. However certain plants species like Ginko biloba and Crataegus have shown promise in experimental and clinical trials. In the present review, some anthropo-geographical and historical perspectives of phytotherapy are mentioned. Some important manifestations of cardiovascular pathology and their phytotherapy are reviewed. The holistic approach of phytotherapy and folkloric ethno medical practices indeed have opened new horizons for quality care in cardiovascular diseases. Phytotherapy and traditional medicine have proven their potential place in the modern and more skeptical evidence based medicine.

    2007-08-01

    Full Text Available BACKGROUND: Treatment recommendations for the same condition from different guideline bodies often disagree, even when the same randomized controlled trial (RCT evidence is cited. Guideline appraisal tools focus on methodology and quality of reporting, but not on the nature of the supporting evidence. This study was done to evaluate the quality of the evidence (based on consideration of its internal validity, clinical relevance, and applicability underlying therapy recommendations in evidence-based clinical practice guidelines. METHODS AND FINDINGS: A cross-sectional analysis of cardiovascular risk management recommendations was performed for three different conditions (diabetes mellitus, dyslipidemia, and hypertension from three pan-national guideline panels (from the United States, Canada, and Europe. Of the 338 treatment recommendations in these nine guidelines, 231 (68% cited RCT evidence but only 105 (45% of these RCT-based recommendations were based on high-quality evidence. RCT-based evidence was downgraded most often because of reservations about the applicability of the RCT to the populations specified in the guideline recommendation (64/126 cases, 51% or because the RCT reported surrogate outcomes (59/126 cases, 47%. CONCLUSIONS: The results of internally valid RCTs may not be applicable to the populations, interventions, or outcomes specified in a guideline recommendation and therefore should not always be assumed to provide high-quality evidence for therapy recommendations.

    2016-04-01

    The rapid growth in scale and complexity of both computational and observational astrophysics over the past decade necessitates efficient and intuitive methods for examining and visualizing large datasets. Here, I present AstroBlend, an open-source Python library for use within the three dimensional modeling software, Blender. While Blender has been a popular open-source software among animators and visual effects artists, in recent years it has also become a tool for visualizing astrophysical datasets. AstroBlend combines the three dimensional capabilities of Blender with the analysis tools of the widely used astrophysical toolset, yt, to afford both computational and observational astrophysicists the ability to simultaneously analyze their data and create informative and appealing visualizations. The introduction of this package includes a description of features, work flow, and various example visualizations. A website - www.astroblend.com - has been developed which includes tutorials, and a gallery of example images and movies, along with links to downloadable data, three dimensional artistic models, and various other resources.

    ASTRO-H is an astrophysics satellite dedicated for X-ray spectroscopic study non-dispersively and to carry out survey complementally, which will be borne out of US-Japanese collaborative effort. Among the onboard instruments there are four conically approximated Wolter-I X-ray mirrors, among which two of them are soft X-ray mirrors\\ of which the energy range is from a few hundred eV to 15 keY, currently being fabricated in the X-ray Optics Lab at Goddard Space Flight Center. The focal point instruments will be a calorimeter (SXS) and a CCD camera (SXI), respectively. The reflectors of the mirror are made of heat-formed aluminum substrate of the thickness gauged of 152 micron, 229 micron, and 305 micron of the alloy 5052 H-19, followed by epoxy replication on gold-sputtered smooth Pyrex cylindrical mandrels to acquire the X-ray reflective surface. The epoxy layer is 10 micron nominal and surface gold layer of 0.2 micron. Improvements on angular response over the Astro-El/Suzaku mirrors come from error reduction on the figure, the roundness, and the grazing angle/radius mismatching of the reflecting surface, and tighter specs and mechanical strength on supporting structure to reduce the reflector positioning and the assembly errors. In this paper, we report the results of calibration of the engineering model of SXT (EM), and project the quality of the flight mirrors.

    Full Text Available The use of water for various treatments (hydrotherapy is probably as old as mankind. Hydrotherapy is one of the basic methods of treatment widely used in the system of natural medicine, which is also called as water therapy, aquatic therapy, pool therapy, and balneotherapy. Use of water in various forms and in various temperatures can produce different effects on different system of the body. Many studies/reviews reported the effects of hydrotherapy only on very few systems and there is lack of studies/reviews in reporting the evidence-based effects of hydrotherapy on various systems. We performed PubMed and PubMed central search to review relevant articles in English literature based on "effects of hydrotherapy/balneotherapy" on various systems of the body. Based on the available literature this review suggests that the hydrotherapy has a scientific evidence-based effect on various systems of the body.

    Both pharmacotherapy and behavioural treatment are required to relieve the symptoms of addictive disorders. This paper reviews the evidence for the benefits of pharmacotherapy and discusses mechanisms where possible. Animal models of addiction have led to some medications that are effective in reducing symptoms and improving function but they do not produce a cure. Addiction is a chronic disease that tends to recur when treatment is stopped; thus, long-term treatment is recommended.

    Full Text Available Psychosocial interventions are an essential part of the treatment for people with severe mental illness such as schizophrenia. The criteria regarding what makes an intervention “evidence-based” along with a current list of evidence-based interventions are presented. Although many evidence-based interventions exist, implementation studies reveal that few, if any, are ever implemented in a given setting. Various theories and approaches have been developed to better understand and overcome implementation obstacles. Among these, merging two evidence-based interventions, or offering an evidence-based intervention within an evidence-based service, are increasingly being reported and studied in the literature. Five such merges are presented, along with their empirical support: cognitive behavior therapy (CBT with skills training; CBT and family psychoeducation; supported employment (SE and skills training; SE and cognitive remediation; and SE and CBT.

  2. Implementation of evidence-based practice: A naturopath perspective.

    Science.gov (United States)

    Ooi, Soo Liang; Rae, John; Pak, Sok Cheon

    2016-02-01

    Evidence-based practice (EBP), an approach to clinical practice that places emphasis on the use of best available research evidence for decision-making, has been adopted broadly in clinical practice. As a patient-focused approach, EBP promotes the spirit of inquiry. It can also facilitate consistency of care across professional boundaries, and clarify the directions of research. However, over-emphasis on systematic reviews and randomised control trials as the "gold standard" for evidence is a major limitation of EBP as it is being practised today. There are also objections to EBP based on epistemological grounds. Complementary and alternative medicine (CAM) therapies often fare unfavourably under the scrutiny of EBP due to the lack of research and inherent differences in healing ideology. Naturopathy is a unique form of CAM, based on both traditional and scientific knowledge. We argue that there is no conflict between naturopathy and EBP. EBP can be adopted as a useful approach to assimilate scientific evidence in naturopathic practices. However, naturopaths need to reconcile tensions between traditional and scientific knowledge in their choice of treatment remedies, while adhering to the naturopathic principles of healing, to benefit the patients. They must also maintain their emphasis on clinical expertise, and also patient preferences and values, in clinical decision-making. PMID:26850801

  3. Evidence-based approach to cutaneous hyperandrogenism in women.

    Schmidt, Timothy H; Shinkai, Kanade

    2015-10-01

    Hirsutism, acne, and androgenetic alopecia are classically considered signs of cutaneous hyperandrogenism (CHA). These common skin findings have significant impacts on the quality of patients' lives and pose the diagnostic challenge of excluding underlying disorders. Many with CHA have normal serum androgen levels. Hirsutism is more strongly associated with hyperandrogenism than are acne or androgenetic alopecia. Variable association of CHA with hyperandrogenemia results from the complexity of the underlying pathophysiology, including factors local to the pilosebaceous unit. CHA often occurs in the setting of polycystic ovary syndrome, the most common disorder of hyperandrogenism, but can also present in uncommon conditions, including nonclassic adrenal hyperplasia and androgen-producing tumors. A thorough history and full skin examination are important to guide appropriate diagnostic evaluation. Oral contraceptive pills with or without antiandrogens can provide therapeutic benefit for hirsutism and acne. Medical options for androgenetic alopecia remain limited. Multidisciplinary approaches may be needed given endocrine, metabolic, reproductive, and psychiatric disorders associated with CHA. More high-quality studies into the mechanisms of CHA and the benefits of antiandrogenic therapies are needed. We provide an evidence-based review of key diagnostic and therapeutic considerations in the treatment of women with CHA. PMID:26138647

    The aim of evidence-based guidelines is primarily to improve patient outcomes without adding to the existing cost of care because both payers and policymakers want to identify health care costs that do not result in benefit to the patient. The purpose of the reported project was to generate a practice guideline for the treatment of uncomplicated acute cystitis in a female population, to determine the extent to which the guideline would be used by providers and to measure the cost and quality of outcomes from its use. A retrospective chart review was used to gather pre-guideline practice and cost data. Measurements included the type, frequency, and duration of antibiotic therapy and the use of urine cultures and both complications and routine followup visits. The implementation of an outpatient practice guideline resulted in a significant change in antibiotic prescribing and a trend toward a change in ordering cultures and clinic followup. There was also a significant decrease in treatment costs. PMID:11061158

    There is a lack of consensus on the safety of the coadministration of drugs and red blood cells (RBCs). A systematic review was undertaken to establish the evidence base for this question and assess how the evidence may be translated into present clinical day practice. Comprehensive searches of MEDLINE, EMBASE, CINAHL, the Cochrane Library and hand searching of transfusion journals, guidelines and websites identified 12 relevant papers: 11 in-vitro experiments and 1 case report. Data on incidences of haemolysis and agglutination following coadministration were extracted and analysed. Overall findings suggest that iron chelators (two papers), antimicrobials (three papers) and lower doses of opioids (three papers) are safe to coadminister with RBCs. Haemolysis was observed with higher doses of opioids (three papers). Transposition of these findings to clinical practice is limited because of the lack of clinical applicability of in-vitro experiments and diversity in how, and what, clinical outcome measures were used. Further evidence from true clinical settings would be required to inform clinical practice on the efficacy and safety of the coadministration of drugs and RBCs. PMID:19302450

  8. Evidence-based Comprehensive Approach to Forearm Arterial Laceration

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available Introduction: Penetrating injury to the forearm may cause an isolated radial or ulnar artery injury, or a complex injury involving other structures including veins, tendons and nerves. The management of forearm laceration with arterial injury involves both operative and nonoperative strategies. An evolution in management has emerged especially at urban trauma centers, where the multidisciplinary resource of trauma and hand subspecialties may invoke controversy pertaining to the optimal management of such injuries. The objective of this review was to provide an evidence-based, systematic, operative and nonoperative approach to the management of isolated and complex forearm lacerations. A comprehensive search of MedLine, Cochrane Library, Embase and the National Guideline Clearinghouse did not yield evidence-based management guidelines for forearm arterial laceration injury. No professional or societal consensus guidelines or best practice guidelines exist to our knowledge. Discussion: The optimal methods for achieving hemostasis are by a combination approach utilizing direct digital pressure, temporary tourniquet pressure, compressive dressings followed by wound closure. While surgical hemostasis may provide an expedited route for control of hemorrhage, this aggressive approach is often not needed (with a few exceptions to achieve hemostasis for most forearm lacerations. Conservative methods mentioned above will attain the same result. Further, routine emergent or urgent operative exploration of forearm laceration injuries are not warranted and not cost-beneficial. It has been widely accepted with ample evidence in the literature that neither injury to forearm artery, nerve or tendon requires immediate surgical repair. Attention should be directed instead to control of bleeding, and perform a complete physical examination of the hand to document the presence or absence of other associated injuries. Critical ischemia will require expeditious

    Here is a postmodern astro-theological response to factual evidence supporting cometary panspermia, including evidence of cyanobacteria fossils in meteorites (Hoover 2011) and diatom frustules in the Polonnaruwa meteorite (Wickramasinghe and others 2013). Distinct from William Derham's modern astro-theology, and in accordance with John Wesley's avoidance of factual demonstrations/proofs and Wesley's appreciation of factual exemplifications, postmodern astro-theology appreciates cometary panspermia. Cometary panspermia is a specific-factually correct example of panspermia in general. Generic panspermia is essential to panentheism. Cometary panspermia enriches evolutionary biology.

    Intervention is a key concept in the technology of psychology and it plays a decisive role in evidence-based research. But analyses of this concept are remarkably sparse. Based on a critical analysis of the conception of intervention in the American Psychological Association’s guidelines for...... evidence-based research and practice, I argue that, while psychological interventions are primarily meant to work in people’s everyday lives, how interventions do so is barely addressed and poorly captured. Evidence-based research, as currently conceived, is an obstacle to overcome this shortcoming...

    Full Text Available The need for understanding and reflecting on evidence-based dermatology (EBD has never been greater given the exponential growth of new external evidence to inform clinical practice. Like any other branch of medicine, dermatologists need to acquire new skills in constructing answerable questions, efficiently searching electronic bibliographic databases, and critically appraising different types of studies. Secondary summaries of evidence in the form of systematic reviews (SR, that is, reviews that are conducted in a systematic, unbiased and explicit manner, reside at the top of the evidence hierarchy, because they are less prone to bias than traditional expert reviews. In addition to providing summaries of the best external evidence, systematic reviews and randomized controlled trials (RCTs are also powerful ways of identifying research gaps and ultimately setting the agenda of future clinical research in dermatology. But like any paradigm, EBD can have its limitations. Wrong application, misuse and overuse of EBD can have serious consequences. For example, mindless pooling together of data from dissimilar studies in a meta-analysis may render it a form of reductionism that does not make any sense. Similarly, even highly protocolised study designs such as SRs and RCTs are still susceptible to some degree of dishonesty and bias. Over-reliance on randomized controlled trials (RCT may be inappropriate, as RCTs are not a good source for picking up rare but important adverse effects such as lupus syndrome with minocycline. A common criticism leveled against SRs is that these frequently conclude that there is lack of sufficient evidence to inform current clinical practice, but arguably, such a perception is grounded more on the interpretation of the SRs than anything else.

    2005-01-01

    We report our experience in bringing science into US and French classrooms. We participated in the US scientific educational program Project ASTRO. It is based on a partnership between a school teacher and an astronomer. They together design and realize simple and interesting scientific activities for the children to learn and enjoy science. We present four hands-on activities we realized in a 4th-grade class (10 yr-old kids) in Tucson (USA) in 2002-2003. Among the covered topics were: the Solar System, the Sun (helioseismology) and the Galaxies. We also present a similar experience done in two classrooms in 2005, in Chatenay-Malabry (France) in partnership with an amateur astronomy association (Aphelie). This is a pleasant and rewarding activity, extremely well appreciated by the children and the school teachers. It furthermore promotes already at a young age the excitement of science, and provides concrete examples of the scientific methodology.

  14. Do You Always Need a Textbook to Teach Astro 101?

    Rudolph, Alexander L

    2013-01-01

    The increasing use of interactive learning strategies in Astro 101 classrooms has led some instructors to consider the usefulness of a textbook in such classes. These strategies provide students a learning modality very different from the traditional lecture supplemented by reading a textbook and homework, and raises the question of whether the learning that takes place during such interactive activities is enough by itself to teach students what we wish them to know about astronomy. To address this question, assessment data is presented from an interactive class, which was first taught with a required textbook, and then with the textbook being optional. Comparison of test scores before and after this change shows no statistical difference in student achievement whether a textbook is required or not. In addition, comparison of test scores of students who purchased the textbook to those who did not, after the textbook became optional, also show no statistical difference between the two groups.

    The Cadmium Zinc Telluride Imager (CZTI) is a high energy, wide-field imaging instrument on AstroSat. CZT's namesake Cadmium Zinc Telluride detectors cover an energy range from 20 keV to > 200 keV, with 11% energy resolution at 60 keV. The coded aperture mask attains an angular resolution of 17' over a 4.6 deg x 4.6 deg (FWHM) field of view. CZTI functions as an open detector above 100 keV, continuously sensitive to GRBs and other transients in about 30% of the sky. The pixellated detectors are sensitive to polarisation above ~100 keV, with exciting possibilities for polarisation studies of transients and bright persistent sources. In this paper, we provide details of the complete CZTI instrument, detectors, coded aperture mask, mechanical and electronic configuration, as well as data and products.

    Based on the present hardware specifications and configurations of the ASTRO-F/FIS (Far-Infrared Surveyor), we are developing a software that simulates the observations with this instrument. Various kinds of detector effects affect the quality of the signal obtained from the detector. In order to correct the signal exactly, we need to analyze the characteristics of the detector and simulate various detector effects. In this presentation, we will show the simulated data sets based on the experimental data measured in the laboratory. Using the simulator, we will discuss the effects of cosmic-ray hitting, transient, crosstalk and non-uniformity of detectors, and propose an appropriate methods for the data reduction.

    Charged Particle Monitor (CPM) on-board the AstroSat satellite is an instrument designed to detect the flux of charged particles at the satellite location. A Cesium Iodide Thallium (CsI(Tl)) crystal is used with a Kapton window to detect protons with energies greater than 1 MeV. The ground calibration of CPM was done using gamma-rays from radioactive sources and protons from particle accelerators. Based on the ground calibration results, energy deposition above 1 MeV are accepted and particle counts are recorded. It is found that CPM counts are steady and the signal for the onset and exit of South Atlantic Anomaly (SAA) region are generated in a very reliable and stable manner.

  1. Evidence based radiation oncology: Breast cancer

    International Nuclear Information System (INIS)

    Purpose: Radiotherapy is, similar to surgery, a local treatment. In the case of breast cancer, it is generally given after conservative or after more extensive, tumour and patient adapted, surgery. The target volumes can be the breast and/or the thoracic wall and/or the regional lymph node areas. The integration and the extent of radiotherapy as part of the comprehensive treatment of the breast cancer patient, including the amount of surgery and the sequencing with the systemic treatments, has to be well discussed with all medical specialists involved in treating breast cancer on a multidisciplinary basis. Guidelines for the appropriate prescription and execution of radiotherapy are of utmost importance. However, individualisation based on the individual patients' and tumours' characteristics should always be envisaged. Materials and methods: Based on a review of the literature the level of evidence that is available for the indications for radiotherapy is summarised, as well as the main clinical questions that are unanswered today. An overview of the recent and ongoing clinical trails in breast cancer will highlight some of the current ongoing debates. Conclusions: In the case of breast cancer, radiotherapy, given after as well conservative as extensive risk-adapted surgery, significantly reduces the risk of local and regional recurrences. Especially for patients with an intermediate to high absolute risk for local recurrences, a positive influence on overall survival has been shown, notably when appropriate radiotherapy techniques are used. Most important is that the best results that we can offer to our breast cancer patients for all clinical endpoints (local and regional control; quality of life; cosmetic results; survival) can be obtained by a multidisciplinary and patient-oriented approach, involving all those involved in the treatment of breast cancer patients

  2. Do You Need a Textbook to Teach Astro 101?

    2011-01-01

    During educational sessions at astronomy meetings, especially during Center for Astronomy Education (CAE) Teaching Excellence workshops, which I have attended and now help present, one of the questions everyone wants to discuss is which textbook to use to teach Astro 101 classes (general education astronomy courses for non-science majors). Some instructors have a favorite. Others will claim that they are all the same and that it doesn't matter. Increasingly, however, the discussions turn to the question of whether any textbook is needed at all. Some of this discussion has been driven by the increase in the use of interactive learning strategies such as Think-Pair-Share questions, Lecture-Tutorials, and Ranking Tasks. These activities provide students a learning modality very different from the traditional lecture supplemented by homework, and raises the question of whether the learning that takes place during such interactive activities is enough to teach students what we wish them to know about astronomy. I had been teaching an Astro 101 class for almost three years using a full suite of interactive learning strategies, when I decided to teach it without requiring the students to purchase a textbook. Comparison of test scores before and after this change shows that there is no statistical difference in student achievement whether a textbook is required or not. Details on the course and methodology used to reach this conclusion will be presented. This work is supported by the National Science Foundation under Grant No. 0847170, a PAARE Grant for the Calfornia-Arizona Minority Partnership for Astronomy Research and Education (CAMPARE), and Grant No. 0715517, a CCLI Phase III Grant for the Collaboration of Astronomy Teaching Scholars (CATS).

    2004-01-01

    In a recent paper (astro-ph/0311364) Alam et al argued that the SNe data of Tonry et al 2003 and Barris et al 2003 appear to favour DE which evolves in time, provided no other priors are invoked. (The effect of invoking priors such as the age of the Universe, the values of $H_0$ and $\\Omega_m$ and CMB/LSS observations could modify this conclusion, as demonstrated in astro-ph/0403687 and other recent papers.) The approach adopted by Alam et al to reconstruct the properties of DE was severely (and, as we shall show below -- unfairly) criticized by J\\"onsson et al in astro-ph/0404468. In this paper we re-examine the parametrisation used in astro-ph/0311364 and show that, contrary to the claims of J\\"onsson et al, the results obtained from this reconstruction are robust and therefore representative of the true nature of dark energy.

    2015-01-01

    Gas motions in galaxy clusters play important roles in determining the properties of the intracluster medium (ICM) and constraining cosmological parameters using X-ray and Sunyaev-Zel'dovich effect observations of galaxy clusters. The upcoming ASTRO-H mission, equipped with high-resolution X-ray spectrometer, will make the first direct measurements of gas motions in galaxy clusters through measurements of Doppler shifting and broadening of emission lines. However, the physical interpretation of the data will be challenging due to the complex thermal and velocity structures of the ICM. In this work, we investigate how well we can measure bulk and turbulent gas motions in the ICM with ASTRO-H, by analyzing mock ASTRO-H simulations of galaxy clusters extracted from cosmological hydrodynamic simulations. We assess how photon counts, spectral fitting methods, multiphase ICM structure, deprojections, and region selection affect the measurements of gas motions. We show that while ASTRO-H is capable of recovering the...

    2014-01-01

    The popularity of natural bodybuilding is increasing; however, evidence-based recommendations for it are lacking. This paper reviewed the scientific literature relevant to competition preparation on nutrition and supplementation, resulting in the following recommendations. Caloric intake should be set at a level that results in bodyweight losses of approximately 0.5 to 1%/wk to maximize muscle retention. Within this caloric intake, most but not all bodybuilders will respond best to consuming ...

    We measured soft X-ray transmission of Optical Blocking Filters for Charge Coupled Device cameras, which will be launched as focal plane detectors of X-ray telescopes onboard the Japanese fifth X-ray astronomical satellite, Astro-E 2. The filters were made from polyimide coated with Al. The X-ray absorption fine structures at the K edges of C, N, O and Al were measured. The depth of the absorption edge of O was deep, compared to the other elements of polyimide. This is the evidence of the oxidation of Al.

  9. Encouraging appropriate, evidence-based use of oral nutritional supplements.

    2010-11-01

    With the considerable cost of disease-related malnutrition to individuals and to society (estimated to be >£13×109 for the UK, 2007 prices), there is a need for effective and evidence-based ways of preventing and treating this condition. The wide range of oral nutritional supplements that may be prescribed for the dietary management of malnutrition and other conditions account for only about 1% (about £99×106, 2007 data) of the prescribing budget in England. Systematic reviews and meta-analyses consistently suggest that ready-made, multi-nutrient liquids which may be prescribed can improve energy and nutritional intake, body weight and have a variety of clinical and functional benefits in a number of patient groups. Meta-analyses have repeatedly shown that oral nutritional supplements produce significant reductions in complications (e.g. infections) and mortality, and a recent meta-analysis shows a reduction in hospital admissions (OR 0·56 (95% CI 0·41, 0·77), six randomised controlled trials). Such benefits suggest that the appropriate use of oral nutritional supplements should form an integral part of the management of malnutrition, particularly as there is currently a lack of evidence for alternative oral nutrition strategies (e.g. food fortification and counselling). As with all therapies, compliance to oral nutritional supplements needs to be maximised and the use monitored. To make sure that those at risk of malnutrition are identified and treated appropriately, there is a need to embed national and local policies into routine clinical practice. In doing so, the economic burden of this costly condition can be curtailed. As recently suggested by the National Institute for Health and Clinical Excellence, substantial cost savings could be made if screening and treatment of malnourished patients was undertaken.

  10. An Evidence Base for Human Spaceflight Risks in Wikipedia

    Science.gov (United States)

    Kundrot, Craig; Steil, Jennifer; Lumpkins, Sarah; Pellis, Neal

    2013-01-01

    NASA's Human Research Program (HRP) is focused on understanding and mitigating thirty two risks to crew health and performance in exploration missions beyond low Earth orbit. The HRP has developed an evidence report for each of the risks. Most evidence reports are a brief review article describing the evidence related to a specified risk, written at a level appropriate for the scientifically educated, non-specialist reader. Each evidence report captured the current state of knowledge from both research and operations. Two limitations of the evidence reports have become apparent: 1) they are updated infrequently and 2) they do not take full advantage of the expertise available in other space agencies and in related fields of terrestrial research. Therefore, the HRP is experimenting with the use of Wikipedia articles as a repository for evidence. Wikipedia's accessibility to the international space flight community and researchers in related terrestrial fields creates the opportunity to generate a more timely and comprehensive evidence base. Initial Wikipedia articles were populated for seven risks using a subset of the information in the HRP-approved evidence reports: Fatigue and Sleep Loss, Treating An Ill or Injured Crew Member, Radiation Carcinogenesis, Visual Impairment and Intracranial Pressure, Renal Stone Formation, Team Cohesion, and Intervertebral Disc Damage. Since the initial articles were created, there have been additions to these Wikipedia articles, including content from sources outside the HRP, and editorial changes to the pages. We will report on the nature of the contributions made after the initial articles were created, the comprehensiveness of the resulting Wikipedia articles, and the effort required to maintain quality control of the content. The Wikipedia approach will also be compared to wiki efforts that exert more traditional editorial control of content prior to posting.

  11. Phenomenological and Astro-particle analysis of light dark matter particles

    International Nuclear Information System (INIS)

    The nature of Dark Matter (DM) is still unveiled. Experimental efforts aiming to detect the Dark Matter have shown a great progress in the last decade. This work is devoted to the phenomenological and astro-particle studies of Dark Matter candidates of supersymmetric nature - the neutralino - and beyond - scalar particles. The former, in the (1-100) GeV mass range, is currently being tested by the Large Hadron Collider, direct detection and indirect detection experiments; this work shows that the interplay between experimental techniques is a decisive tool to thoroughly search for theoretical predictions. The latter is a non-standard candidate as light as 1 MeV which could be copiously produced at the Large Hadron Collider and, at the same time, it could explain other phenomena such as neutrino masses and/or the 511 keV line from the galactic center of the Milky Way. We start by describing the DM problem in Part I, where we give a review for evidence of the existence of DM, we set the cosmological framework in which we work and describe the history of DM from the Early Universe (EU), to the formation of structure and up to the current distribution of the DM in haloes. Then, in Part II, we go through the important Cosmological, Astro-particle and Particle Physics constraints to particle DM candidates and subsequently introduce models providing relatively light DM candidates, models of standard supersymmetric nature such as the Minimal Supersymmetric Standard Model (MSSM) and the Next-to-MSSM (NMSSM) with neutralino DM, and beyond N=1 SUSY in a light scalar DM scenario inspired in N=2 SUSY. Finally, in Part III we present the findings of the investigations carried out: we describe a numerical tool developed to scan the multidimensional supersymmetric parameter space, then we present an application of this tool to the search of light neutralino configurations in the MSSM and NMSSM as well as an application to the search for neutralino DM in directional detectors, and

  12. Identifying Challenges to Building an Evidence Base for Restoration Practice

    2015-11-01

    Full Text Available Global acknowledgement of ecological restoration, as an important tool to complement conservation efforts, requires an effort to increase the effectiveness of restoration interventions. Evidence-based practice is purported to promote effectiveness. A central tenet of this approach is decision making that is based on evidence, not intuition. Evidence can be generated experimentally and in practice but needs to be linked to baseline information collection, clear goals and monitoring of impact. In this paper, we report on a survey conducted to assess practitioners’ perceptions of the evidence generated in restoration practice in South Africa, as well as challenges encountered in building this evidence base. Contrary to a recent assessment of this evidence base which found weaknesses, respondents viewed it as adequate and cited few obstacles to its development. Obstacles cited were mostly associated with planning and resource availability. We suggest that the disparity between practitioners’ perceptions and observed weaknesses in the evidence base could be a challenge in advancing evidence-based restoration. We explore opportunities to overcome this disparity as well as the obstacles listed by practitioners. These opportunities involve a shift from practitioners as users of scientific knowledge and evidence, to practitioners involved in the co-production of evidence needed to increase the effectiveness of restoration interventions.

    Full Text Available AbstractPurpose: The objective of the study was to compare a traditionally structured journal club with an evidence based structured journal club during an advanced clinical pharmacy rotation and to determine the best utilization that aligns with recent changes to the pharmacy school accreditation standards.Methods: The study included 21 students who completed journal club utilizing the traditional journal club format and 24 students who utilized an evidence based journal club format. Background characteristics, student reported beliefs, and mean critical evaluation skills scores were evaluated and compared in each group.Results: There were no statistically significant differences between the two cohorts in mean overall percentage grade for the activity. Students in the traditional cohort received significantly higher grades for the Study Analysis and Critique section (90.97 + 12.18 versus 81.25 + 11.18, P=0.01 as well as for the Preparedness section (96.11 + 8.03 versus 85.0 + 17.13, P=0.002. Students in the evidence based cohort received statistically superior grades for the Presentation Skills section (96.43 + 6.39 versus 82.47 + 14.12, P=0.0004.Conclusion: An evidence based journal club is a reasonable and effective alternative to the traditionally structured journal club when the primary objective is to assist students in understanding evidence based concepts and to apply current literature to clinical practice.

    Public attention to evidence-based health care (EBHC) has increased significantly in recent years. Key problems related to applying EBHC in current healthcare practice include the timely update of up-to-date knowledge and skills and the methodology used to implement EBHC in clinical settings. EBHC has been introduced to the Taiwan healthcare system for the past two decades. The annual EBM (Evidence based medicine) National Competition is a unique and important EBHC activity in Taiwan. EBHC has been promoted widely in medicine, nursing, pharmacy, public health and other professions, and EBHC-related organizations such as the Taiwan Evidence Based Medicine Association (TEBMA), and Taiwan Evidence Based Nursing Association (TEBNA), have increased in number and grown in membership. In addition to domestic developments, Taiwan is also actively involved in global organizations, such as the Cochrane Collaboration, East Asian Cochrane Alliance (EACA), and the International Society for Evidence Based Health Care (ISEHC). In Taiwan, most medical professionals work cooperatively to promote EBHC, which facilitates the gradual improvement of healthcare quality. PMID:25464951

    First-generation citizen science projects (such as Galaxy Zoo) have proven very successful at utilizing the efforts of volunteers (human computation) to attack specific problem areas, such as certain types of image analysis, where machines are not currently especially effective. However, there has been little or no attempt in these to capture or transfer the domain knowledge from carbon-based to silicon-based systems. AstroCollation is a next generation collaborative science venture that aims to foster a more synergistic relationship between humans and machines around transient astronomy. Data mining algorithms will be applied to transient event data to produce conceptual models describing them. These models will then be presented to citizen scientists for value judgments, deciding which of a set of models provides the best description, as well as providing contextual information to aid the classification process. Finally decisions and information are factored back into the system and consolidated to produce a consensus description of an event. The project is predicated upon semantic technologies - allowing the formal representation of conceptual relations within a particular domain - and will leverage data and infrastructure from the Catalina Real-time Transient Survey and SkyAlert system. It will address such issues as the formal treatment of uncertainty in data, how to map a multistage computational process to a simple and minimal interface or set of interfaces, and how to fold human computation into a workflow process where time criticality can be important.

    2012-01-01

    The Astro-H is led by the Japanese Space Agency (JAXA) in collaboration with many other institutions including the NASA Goddard Space Flight Center. Goddard's contributions include two soft X-ray telescopes (SXTs). The telescopes have an effective area of 562 square cm at 1 keV and 425 square cm at 6 keV with an image quality requirement of 1.7 arc-minutes half power diameter (HPD). The engineering model has demonstrated 1.1 arc-minutes HPD error. The design of the SXT is based on the successful Suzaku mission mirrors with some enhancements to improve the image quality. Two major enhancements are bonding the X-ray mirror foils to alignment bars instead of allowing the mirrors to float, and fabricating alignment bars with grooves within 5 microns of accuracy. An engineering model SXT was recently built and subjected to several tests including vibration, thermal, and X-ray performance in a beamline. Several lessons were learned during this testing that will be incorporated in the flight design. Test results and optical performance are discussed, along with a description of the design of the SXT.

    We are designing an X-ray CCD camera (SXI) for ASTRO-H, including many new items. We have developed the CCD, CCD-NeXT4, that is a P-channel type CCD. It has a thick depletion layer of 200μm with an imaging area of 30mm square. Since it is back-illuminated, it has a good low energy response and is robust against the impact of micro-meteorites. We will employ 4 chips to cover the area of 60mm square. A mechanical rather than peltier cooler will be employed so that we can cool the CCD to -120°C. We will also introduce an analog ASIC that is placed very close to the CCD. It performs well, having a similar noise level to that assembled by using individual parts used on SUZAKU. We also employ a modulated X-ray source (MXS), that improves the accuracy of the calibration. The SXI will have one of the largest SΩ among various satellites.

    We present a preview of a new, fully on-line astronomy course for undergraduate non-science majors at Penn State, to be offered for the first time in Spring 2007, with an expected enrollment of 300-600 students. The entire course content is conveyed through an interactive story, capitalizing on the many multimedia astronomy resources publically available on the WWW. The four units of the course, basic astronomy and the nighttime sky, our solar system, stars and the Milky Way Galaxy, and extragalactic astronomy and cosmology deliver the same content as a traditional Astro 001 course. The story for our first unit involves a student abducted by aliens and taken to another planet. There the student is confronted with puzzles involving a different stellar system configuration. The final unit involves a student's quest for a career, aided by visits to alien civilizations in which they explain their varied views of life which is shaped by cosmological findings. The four units are united by a character, the Riddler, who poses riddles about various aspects of the course, and whose identity and purpose is revealed gradually as a reward for completion of various subtopics. This initial offering of the course will be entirely web-based except for traditional evening in-class exams. Our own exams and a standardized preand post-assessment will be used to benchmark our students' performance against those from our traditional course. We gratefully acknowledge funding from an STScI IDEAS award.

    For more than a decade, nursing education has experienced several significant changes in response to challenges faced by healthcare organizations. Accrediting organizations have called for improved quality and safety in care, and the Institute of Medicine has identified evidence-based practice and quality improvement as 2 core competencies to include in the curricula for all healthcare professionals. However, the application of these competencies reaches far beyond the classroom setting. For nurses to possess the knowledge, skills, and attitudes to apply evidence-based practice and quality improvement to the real-world setting, academic-clinical institution partnerships are vital.

    2016-01-01

    This paper discusses an evidence-based approach to software requirements engineering. The approach is called evidence-based, since it uses publications on the specific problem as a surrogate for stakeholder interests, to formulate risks and testing experiences. This complements the idea that agile software development models are more relevant, in which requirements and solutions evolve through collaboration between self-organizing cross-functional teams. The strategy is exemplified and applied to the development of a Software Requirements list used to develop software systems for patient registries. PMID:27577464

    Evidence-based nursing practice requires the use of effective search strategies to locate relevant resources to guide practice change. Continuing education and staff development professionals can assist nurses to conduct effective literature searches. This article provides suggestions for strategies to aid in identifying search terms. Strategies also are recommended for refining searches by using controlled vocabulary, truncation, Boolean operators, PICOT (Population/Patient Problem, Intervention, Comparison, Outcome, Time) searching, and search limits. Suggestions for methods of managing resources also are identified. Using these approaches will assist in more effective literature searches and may help evidence-based practice decisions.

    Through this article the authors describe how schools of social work offering a child and adolescent trauma specialization actively partnered with their community-based field placement agencies to achieve a dual purpose: help agencies sustain the capacity for evidence-based trauma treatment (EBTT) and provide sufficient EBTT MSW student field placement sites that support preparation of trauma-informed practitioners by schools of social work. Development and description of the specific conceptual framework used to inform the trauma-informed organizational change initiative is described. Results of an Organizational Readiness assessment undertaken at six agencies reflect a strong alignment between implementation drivers identified in the literature (Fixsen, Blase, Naoom, & Wallace, 2009) and the conceptual framework. The manner in which these results are being used by schools of social work and their agency partners in sustaining the implementation of evidence-based trauma treatment is reviewed, and implications for future research, education, and practice is discussed.

    Anxiety disorders are the most common mental health disorder among children and adolescents. We examined 111 treatment outcome studies testing 204 treatment conditions for child and adolescent anxiety published between 1967 and mid-2013. Studies were selected for inclusion in this review using the PracticeWise Evidence-Based Services database. Using guidelines identified by this journal (Southam-Gerow & Prinstein, 2014 ), studies were included if they were conducted with children and/or adolescents (ages 1-19) with anxiety and/or avoidance problems. In addition to reviewing the strength of the evidence, the review also examined indicators of effectiveness, common practices across treatment families, and mediators and moderators of treatment outcome. Six treatments reached well-established status for child and adolescent anxiety, 8 were identified as probably efficacious, 2 were identified as possibly efficacious, 6 treatments were deemed experimental, and 8 treatments of questionable efficacy emerged. Findings from this review suggest substantial support for cognitive-behavioral therapy (CBT) as an effective and appropriate first-line treatment for youth with anxiety disorders. Several other treatment approaches emerged as probably efficacious that are not primarily CBT based, suggesting that there are alternative evidence-based treatments that practitioners can turn to for children and adolescents who do not respond well to CBT. The review concludes with a discussion of treatments that improve functioning in addition to reducing symptoms, common practices derived from evidence-based treatments, mediators and moderators of treatment outcomes, recommendations for best practice, and suggestions for future research.

    With the increasing emphasis on evidence-based nursing practice, nurse educators need to more fully implement teaching strategies that help students gain critical thinking skills related to inquiry and understand the importance of evidence-based nursing practice. Research and scholarship emphases in one baccalaureate nursing program, student-identified benefits, and challenges associated with incorporating inquiry across the curriculum are described in this article. In clinical journal entries, students described the following benefits associated with curricular emphasis on inquiry: increased interest in evidence-based nursing practice and participating in the generation of research; enhanced critical thinking skills through the development of knowledge, experience, and competencies; increased motivation to continue professional growth and development by participating in lifelong learning; the desire to become better consumers of research findings; better understanding of the "real world" of clinical research; and increased desire to pursue graduate studies in nursing. The challenge to promote student growth toward competence in the application of evidence-based principles in clinical practice is ongoing. PMID:15719712
