Nervous system disorders are among the most severe disorders. Significant breakthroughs in contemporary clinical practice may provide brain-computer interfaces (BCIs) and neuroprostheses (NPs). The aim of this article is to investigate the extent to which the ethical considerations in the clinical application of brain-computer interfaces and associated threats are being identified. Ethical considerations and implications may significantly influence further development of BCIs and NPs. Moreover, there is significant public interest in supervising this development. Awareness of BCIs’ and NPs’ threats and limitations allow for wise planning and management in further clinical practice, especially in the area of long-term neurorehabilitation and care. 相似文献

The coming into force of Directive 2001/20/EC represented a step forward in harmonising clinical trial regulation in European countries, guaranteeing a uniform protection of subjects participating in clinical research across Europe. However, it led to a disproportionate increase in the bureaucratization, and thus, it became evident that procedures needed to be simplified without detriment to patient’s safety. Thus, Regulation 536/2014, that repealed Directive 2001/20/EC, with the aim of decreasing the growing bureaucratization and stimulating clinical research in Europe, established simplified procedures, such as regulating a common procedure for authorising trials in Europe, the institution of strict assessment timelines, or the definition of new concepts, such as “low-intervention clinical trial”. The legal form of a Regulation allowed the norm to be directly applied to Member States without the need for transposition. By means of the new Royal Decree, the national legislation is adapted to make the application of the regulation feasible and it allows the development of the aspects that the Regulation leaves to national legislation. Both documents seek to stimulate clinical research with medicinal products to foster knowledge, facilitate transparency, and reinforce subjects’ safety. This will surely be the case, but with this revision, we will look at the novelties and key aspects that are most relevant to investigators and we will analyse the consequences for all parties involved in clinical research. 相似文献

AIM: To study the significance of cap-fitted colonoscopy in improving cecal intubation time and polyp detection rate. METHODS: This study was a prospective randomized controlled trial conducted from March 2008 to February 2009 in a tertiary referral hospital at Sydney. The primary end point was cecal intubation time and the secondary endpoint was polyp detection rate. Consecutive cases of total colonoscopy over a 1-year period were recruited. Randomization into either standard colonoscopy (SC) or cap-assist... 相似文献

The accurate identification of the nursing diagnoses and the corresponding measurement of their indicators will depend on the elements in the standardized language systems.
OBJECTIVE
To analyze the correspondence between elements of four NANDA‐I nursing diagnoses and outcomes suggested by the nursing outcomes classification (NOC) for the resolution of these diagnoses.METHOD
A methodological study consisting of cross‐mapping was performed in the first stage between definitions, defining characteristics (DCs), and related factors (RFs) of impaired oral mucous membrane, impaired tissue integrity, spiritual distress, and delayed surgical recovery and outcome definitions and indicators to measure results of diagnoses resolution and an analysis of its relevance by experts in the second stage.RESULTS
It found partial correspondence between outcome indicators, DCs, RFs, and definitions.CONCLUSION
The data evidence the relevance of this review for a reliable application of these taxonomies and demonstrated partial correspondence between concepts analyzed. A identificação precisa dos diagnósticos de enfermagem e a medida correspondente dos seus indicadores dependerá dos elementos nos sistemas de linguagem padronizados.OBJETIVO
Foi analisar a correspondência entre os elementos de quatro NANDA‐I diagnósticos de enfermagem e os resultados sugeridos pelo NOC para a resolução destes diagnósticos.MÉTODO
um estudo metodológico que consiste em cross‐mapping foi realizado em uma primeira fase entre as definições, características definidoras e fatores relacionados de Mucosa oral prejudicada, Integridade tissular prejudicada, Sofrimento espiritual e Recuperação cirúrgica retardada e as definições dos resultados indicados para a resolução destes diagnósticos; na segunda fase, foi realizada uma análise desta concordância por especialistas.RESULTADOS
correspondência parcial entre as definições dos diagnósticos e dos resultados, características definidoras e fatores relacionados.CONCLUSÃO
Os resultados evidenciam a relevância dessa avaliação para uma aplicação confiável destas taxonomias e demonstrou a correspondência parcial entre os conceitos analisados. 相似文献57.

Objective
To describe the impact of a standard hospital educational intervention including active physical exercises on personal well-being, functional capacity and knowledge of the benefits of prescribed physical activity for patients undergoing haemodialysis.Method
An uncontrolled, quasi-experimental, before-and-after study with repeated measures of response variables at 4, 8 and 12 weeks after participating in an educational and physical exercise hospital intervention. It was performed at the Nephrology Unit at the Hospital Complex in Vic within september and december 2014. The patients’ well-being, functional capacity and knowledge were assessed. Assessment tools: NOC nursing indicators, Barthel index scale, FAC Holden, Timed Get Up and Go test and Daniels scale.Results
We included 68 (80.0%) patients and 58 (85.3%) completed, with a mean age of 70.16 ± 13.5 years; 62.1% were males. After 12 weeks, the patients had better scores of personal well-being (2.33 ± 1.2, 3.88 ± 0.8), more autonomy to perform activities of daily living (Barthel: 92.8 ± 12.8; 93.5 ± 13.9), more muscle strength (Daniels Scale: 3.81 ± 0.7, 4.19 ± 0.6) and walked more briskly (Get Up and Go test: 14.98 ± 8.5; 15.65 ± 10.5). All of the score differences were statistically significant (P < 05) except the Barthel Index.Conclusions
The standard educational intervention and active exercise performed at hospital level improved the personal well-being, knowledge and functional capacity of patients on haemodialysis. 相似文献58.
