看護の専門職的自律性に関与する要因

原著論文Original Paper臨床で働く看護師153名(有効回答数137名)を村象に、菊池らの専門職的自律性測定尺度を用いて、看護の専門職的自律性に関与している諸要因を明らかにした。自律性に関与する要因としては、職務信頼度が最も重要な要因として挙げられ、次に重要な要因として臨床経験年数が挙げられた。さらに、役職、研修・研究(継続教育)の経験が自律性を高める傾向にあることが示唆された

Continuous versus intermittent antibiotics for bronchiectasis

Background Bronchiectasis is a chronic airway disease characterised by a destructive cycle of recurrent airway infection, inflammation and tissue damage. Antibiotics are a main treatment for bronchiectasis. The aim of continuous therapy with prophylactic antibiotics is to suppress bacterial load, but bacteria may become resistant to the antibiotic, leading to a loss of effectiveness. On the other hand, intermittent prophylactic antibiotics, given over a predefined duration and interval, may reduce antibiotic selection pressure and reduce or prevent the development of resistance. This systematic review aimed to evaluate the current evidence for studies comparing continuous versus intermittent administration of antibiotic treatment in bronchiectasis in terms of clinical efficacy, the emergence of resistance and serious adverse events. Objectives To evaluate the effectiveness of continuous versus intermittent antibiotics in the treatment of adults and children with bronchiectasis, using the primary outcomes of exacerbations, antibiotic resistance and serious adverse events. Search methods On 1 August 2017 and 4 May 2018 we searched the Cochrane Airways Review Group Specialised Register (CAGR), CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL, and AMED. On 25 September 2017 and 4 May 2018 we also searched www.clinicaltrials.gov, the World Health Organization (WHO) trials portal, conference proceedings and the reference lists of existing systematic reviews. Selection criteria We planned to include randomised controlled trials (RCTs) of adults or children with bronchiectasis that compared continuous versus intermittent administration of long-term prophylactic antibiotics of at least three months' duration. We considered eligible studies reported as full-text articles, as abstracts only and unpublished data. Data collection and analysis Two review authors independently screened the search results and full-text reports. Main results We identified 268 unique records. Of these we retrieved and examined 126 full-text reports, representing 114 studies, but none of these studies met our inclusion criteria. Authors' conclusions No randomised controlled trials have compared the effectiveness and risks of continuous antibiotic therapy versus intermittent antibiotic therapy for bronchiectasis. High-quality clinical trials are needed to establish which of these interventions is more effective for reducing the frequency and duration of exacerbations, antibiotic resistance and the occurrence of serious adverse events. Plain language summary Are antibiotics more effective when given continuously or intermittently to people with bronchiectasis? Background Bronchiectasis is an incurable lung disease characterised by repeated chest infections. Antibiotics are a main form of treatment and can be taken long term to prevent chest infections from developing. This could be continuously or intermittently for a fixed period of time. However, we do not currently know which approach is the most effective for reducing the frequency and duration of exacerbations, managing antibiotic resistance and minimising side effects. Study Characteristics On 1 August 2017 we searched a wide range of sources to find clinical trials for our review. We found 268 potentially relevant results but on closer examination none of the studies met our review criteria and none could be included. Authors' conclusions There is no high-quality evidence about whether continuously administered or intermittently administered antibiotics are safer and more helpful for people with bronchiectasis. More research is needed to evaluate which one of these methods is better for reducing chest infections, limiting resistance to antibiotic therapy and reducing serious side effects

Performance of Wide-Angle Two-Dimensional Diffusers with Vane Systems (3rd Report)

In the previous works, experiments were made with flat vanes in diffusers with divergence angles of 30°, 40°, and 60°, and showed the basic criteria for effective vane configurations with source-point translation. In the present work, tests were made with flat vanes in two-dimensional diffusers, to determine the relation between pressure recovery and flow regime. For the optimum vane configurations with source-point translation on the pressure recovery, the flow regime in the downstream duct is also greatly improved. The area of separation is considerably reduced, and the velocity profiles in the downstream duct can be flattened. However, the section where the velocity profile is to be uniform can be attained at the far distance in the downstream duct, compared with the pressure recovery section

Performance of the Wide-Angle Two-Dimensional Diffusers with Various Inlet Shear Flows (1st Rept. In Case of Uniform Shear Flows)

Experimental studies of the two dimensional diffusers with inlet uniform shear flows in the parallel walls were carried out. In general, the performance of the diffusers with inlet simple shear flows for small divergence angle was lower compared with the diffusers having uniform inlet velocity profiles. However, the pressure-recovery performance of wide-angle diffusers with uniform inlet shear flows was slightly higher than that of the diffusers with uniform inlet velocity profiles. This is characterized by the effects of the variations of spanwise velocity gradients and the secondary flows in the diffusers
