Impact of pharmacy outreach services on blood pressure management in the elderly community of Hong Kong

Aim: To investigate the impact of the Pharmacy Outreach Service (POS) on blood pressure (BP) and disease knowledge among community‐dwelling elderly patients with hypertension, and to evaluate the sustainability of such impact of POS. Methods: A prospective open‐labeled study of elderly adults (aged ≥65 years) with hypertension (BP ≥140/90 mmHg for non‐diabetics and ≥130/80 mmHg for diabetics) was carried out at seven elderly community centers from July 2008 to March 2010. Pharmacists provided BP monitoring, medication review and disease knowledge assessment. The target BP was <140/90 mmHg for non‐diabetics and <130/80 mmHg for diabetics. The primary outcome was BP change, whereas the secondary outcome was the change of disease knowledge of hypertension. All outcomes were compared between baseline and the last visit. For POS 2008/09 participants, BP was compared between values obtained during POS 2008/09 and 2009/10. Results: A total of 97 participants were recruited. Systolic BP reduced significantly from 152.38 ± 18.80 mmHg to 147.04 ± 20.72 mmHg (P = 0.021), and diastolic BP reduced from 73.84 ± 11.36 mmHg to 71.03 ± 10.97 mmHg (P = 0.010). Cumulative reductions in mean systolic BP and diastolic BP throughout the 2‐year study period were 21.39 ± 24.72 mmHg and 9.88 ± 13.48 mmHg, respectively (P < 0.001). A 12% increase in the at‐goal rate was observed in new participants recruited in 2009 (P = 0.039). Disease knowledge of hypertension improved significantly (P < 0.005), particularly in areas that included the definition of hypertension, diet and lifestyle modification. Conclusions: The POS might improve blood pressure control, hypertension and diabetes knowledge in elderly adults with hypertension in Hong Kong. The effect on blood pressure improvement was sustainable. Geriatr Gerontol Int 2013; 13: 175–181.     

继续医学教育活动的有效性

继续医学教育的目的是通过向医生提供最新的医学知识和技能,使医生在其整个职业生涯中,一直保持较高的医疗水平.但目前还没有充足的证据能证明继续医学教育活动的有效性,以及在继续医学教育活动中哪些教育方法和技术能最有效地传播和记忆医学知识.为了全面、系统地评估继续医学教育活动的有效性,以及了解不同的教育手段对医生知识、态度、技能、临床表现和临床效果的作用.美国约翰·霍普金斯大学医学院、美国医疗保健研究与质量管理署和美国胸科医师学会的专家共同进行了一项系统回顾性研究.     

Metastatic colon cancer: correlation of oxygen levels with I-131 F(ab')2 uptake

Tumor oxygen levels were measured with an electrode in 13 patients with colon carcinoma metastases. These measurements were correlated with images obtained with radiolabeled monoclonal antibody 1083-17-1A. Only those tumors or tumor regions with a mean PO2 of 16 mm Hg or greater were successfully imaged. Tumors and tumor regions with a mean PO2 of less than 16 mm Hg were not imaged, even when the presence of antigen was confirmed with biopsy. These data suggest that physiologic factors other than antigen expression may affect antibody uptake.     

柱切换HPLC法研究米托蒽醌毫微粒冻干静脉注射剂的药代动力学

建立了血浆中米托蒽醌的柱切换高效液相色谱测定法,测定和比较了米托蒽醌溶液型注射剂和毫微粒冻干静脉注射剂在家兔体内的血药曲线,并研究比较了二者的药代动力学参数。米托恩醌毫微粒冻干注射剂使米托蒽醌在血中浓度大为降低,血中分布容积增大了近5倍,体内平均驻留时间延长了2倍多。表明米托蒽醌毫微粒有明显的体内长效作用,结合其体内分布试验研究结果,表明其具有明显肝靶向分布作用。
