量化体育锻炼对维持性血液透析患者生活质量和疾病转归的影响

目的:观察量化体育锻炼对维持性血液透析(MHD)患者的应用效果,探讨临床治疗体会。方法:将64例MHD患者随机分成2组各32例,对照组给予常规健康宣教、干预治疗和自主锻炼,观察组在其基础上给予量化体育锻炼干预治疗;观察2组患者的运动量指标变化情况,比较生活质量和疾病转归等相关指标。结果:干预6个月后,2组的上肢锻炼时间和步行运动量均较干预前明显提高(P0.01,0.05),观察组的提高幅度更高于对照组(P0.01);2组的疲乏状态、日常生活活动能力(ADL)、焦虑自评量表(SAS)和睡眠质量评分量表(SPIEGEL)等指标均较干预前明显降低(均P0.05),改良SGA评分明显提高(P0.01,0.05),观察组的改善幅度更高于对照组(P0.01)。治疗后,观察组的内瘘血管良好率和肾功能平稳率高于对照组(均P0.05),并发症率和再入院率降低(P0.05)。结论:对MHD患者给予量化体育锻炼干预治疗,能显著提高康复锻炼的运动量和优化锻炼效果,提高患者的生活质量,改善疾病预后。     

Evaluation of long-term efficacy,safety, and effect on life quality of pulsed dye laser in rosacea patients

Background: Rosacea is a chronic disease affecting the patients’ life quality negatively. Although various laser systems are used in the rosacea treatment, studies reporting efficacy and long-term continuity of benefit of laser therapies are scarce.

Objectives: We aimed to evaluate the efficacy, safety, continuity of benefit, and effect on life quality of pulsed dye laser (PDL) in the rosacea patients.

Methods: Fourteen rosacea patients treated with PDL were enrolled in the study. The number of treatment sessions were varied from one to four. The efficacy was evaluated by the physicians’ clinical assessment (PCA), patients’ self-assessment (PSA), and erythema and telengiectasia grading scores. Additionally, the patients were asked about the continuity of the benefit and improvement in their life qualities after the treatment.

Results: Both the erythema and telangiectasia scores were significantly improved after the treatment (p < 0.001). According to PCA, nine patients had a clinical improvement of >50%. According to PSA, 11 patients had good/excellent improvement. Moderate/significant benefit of treatment continued in 12 patients at the follow-up period (mean 21.64 ± 14.25 months). The life quality scores were significantly improved. No serious side effects were observed.

Conclusion: PDL has high and long-term efficacy in the treatment of rosacea with a good safety profile.     

The need for new control strategies for particulate matter in parenterals

An undesirable characteristic in lyophilized parenteral products is the potential presence of particulate matter in the final product, which may affect patient safety. In this study, quality risk management tools described in the International Conference on Harmonization Guideline Q9 were used to estimate the risks for a pharmaceutical manufacturing line, based on three critical quality attributes: (1) visible particulate matter; (2) lyo-cake collapse traces; and (3) lyo-cake melt-back traces. Together with a Process Failure Mode Effect Analysis (PFMEA), an input-output analysis of the individual unit operations identified seven major material classes of extrinsic particulate matter. In addition to the process assessment, an experimental investigation of the location of impurities in lyophilized products was performed. To that end, intentionally contaminated vials were examined to locate the particulate matter and its possible migration. The results emphasize the importance of a full transmission mode release testing since the particles may enter the interior of the lyo-cake. A theoretical explanation of the observed impurity locations is provided.     

Barriers to the use of patient safety information sources by community pharmacies

BackgroundWhen patient safety information is communicated across a regulatory jurisdiction or country, the potential to enhance the safety of community pharmacy practice is significant. While there currently exists a number of sources for patient safety information (e.g., websites, safety bulletins, online tools), knowledge of the barriers that may inhibit the use of such information sources within community pharmacies is limited.ObjectiveThis research explores community pharmacy manager use of Canadian patient safety information sources and the barriers that may limit the use of such sources.MethodsA qualitative research study design using semi-structured interviews was conducted with 15 community pharmacy managers in the Halifax Regional Municipality of Nova Scotia, Canada. The study explored how pharmacists access and engage a variety of information sources, including corporate intranets, websites, and tools provided by third party data base repositories. Interview data were analyzed using thematic analysis.ResultsFive general barriers were identified: lack of time to access information sources and its contents; too many sources of available information; too much information not relevant to community pharmacy practice; complexity navigating online information sources; and lack of community pharmacy involvement in source design.ConclusionWhile pharmacies do use safety information sources to enhance practice safety, their ability to incorporate this information is inhibited by their general lack of time available to access and read safety information, lack of knowledge about where to get this information, and lack of tailored information for the community pharmacy context. Future initiatives should address increasing information awareness of available sources, consolidating and reducing information overload of such sources, and packaging information to better fit with pharmacists’ needs.     

Collagenous colitis without diarrhoea at diagnosis – a follow up study

Objective: Chronic watery diarrhoea is a classical symptom of collagenous colitis (CC). However, in some cases, the typical histologic findings of CC can be found in patients without this symptom. In this study we have performed a follow up on patients with a confirmed histological diagnosis of CC without the typical symptom watery diarrhoea.

Patients and methods: A structured medical record follow-up was performed on the subgroup of patients without watery diarrhoea but diagnosed with the typical CC histologic appearance in a previous study of microscopic colitis.

Results: At follow up after a median time of 8 years (range: 0.33–12 years), five of these fifteen patients developed bowel symptoms but only two developed characteristic CC symptoms with watery diarrhoea.

Conclusion: The majority of patients without chronic watery diarrhoea at diagnosis remained free from this symptom during follow up and only in a few cases symptoms attributed to CC developed.
