Priorities for content for a short-course on postoperative care relevant for low- and middle-income countries: an e-Delphi process with training facilitators

Most surgical and anaesthetic mortality and morbidity occurs postoperatively, disproportionately affecting low- and middle-income countries. Various short courses have been developed to improve patient outcomes in low- and middle-income countries, but none specifically to address postoperative care and complications. We aimed to identify key features of a proposed short-course addressing this topic using a Delphi process with low- and middle-income country anaesthesia providers trained as short-course facilitators. An initial questionnaire was co-developed from literature review and exploratory workshops to include 108 potential course features. Features included content; teaching method; appropriate participants; and appropriate faculty. Over three Delphi rounds (panellists numbered 86, 64 and 35 in successive cycles), panellists indicated which features they considered most important. Responses were analysed by geographical regions: Africa, the Americas, south-east Asia and Western Pacific. Ultimately, panellists identified 60, 40 and 54 core features for the proposed course in each region, respectively. There were high levels of consensus within regions on what constituted core course content, but not between regions. All panellists preferred the small group workshop teaching method irrespective of region. All regions considered anaesthetists to be key facilitators, while all agreed that both anaesthetists and operating theatre nurses were key participants. The African and Americas regional panels recommended more multidisciplinary healthcare professionals for participant roles. Faculty from high-income countries were not considered high priority. Our study highlights variability between geographical regions as to which course features were perceived as most locally relevant, supporting regional adaptation of short-course design rather than a one-size-fits-all model.

Cabergoline compared to levodopa in the treatment of patients with severe restless legs syndrome: results from a multi-center, randomized, active controlled trial.

We report the first large-scale double-blind, randomly assigned study to compare two active dopaminergic therapies for Restless Legs Syndrome (RLS), the dopamine agonist cabergoline (CAB) and levodopa/benserazide (levodopa). Patients with idiopathic RLS were treated with fixed daily doses of 2 or 3 mg CAB or 200 or 300 mg levodopa for 30 weeks. Efficacy was assessed by changes in the IRLS (International RLS Severity Scale) and by time to discontinuation of treatment due to loss of efficacy or augmentation. 361 of 418 screened patients (age 58 +/- 12 years, 71% females) were randomly assigned and treated (CAB: n = 178; levodopa: n = 183) in 51 centers of four European countries. Baseline IRLS total score was 25.7 +/- 6.8. The baseline-adjusted mean change from baseline to week 6 in IRLS sum score was d = -16.1 in the CAB group and d = -9.5 in the levodopa group (d = -6.6, P < 0.0001). More patients in the levodopa group (24.0%) than in the CAB group (11.9%, P = 0.0029, log-rank test) discontinued because of loss of efficacy (14.2% vs. 7.9%, P = 0.0290) or augmentation (9.8% vs. 4.0%, P = 0.0412). Adverse events (AEs) occurred in 83.1% of the CAB group and in 77.6% of the levodopa group. In both groups, most frequent AEs were gastrointestinal symptoms (CAB: 55.6%, levodopa: 30.6%, P < 0.0001). This first large-scale active controlled study in RLS showed superior efficacy of cabergoline versus levodopa after a 30-week long-term therapy. Tolerability was found more favorable with levodopa than with cabergoline.

南岳毛尖抑制小鼠移植性S_(180)生长作用的初步研究

本研究用南岳毛尖(一级绿茶)浸泡液灌胃处理皮下移植S_(180)的Babl/c小白鼠,观察其抑瘤效果。结果表明该绿茶可明显抑制肿瘤的生长,瘤重明显轻于对照组(P<0.05);空泡变性瘤细胞数、瘤块内坏死灶数明显多于对照组(P<0.001);瘤细胞核分裂数明显少于对照组(P<0.005),对瘤细胞有较好的杀灭作用。该研究证明南岳毛尖是一种天然防癌抗癌物质,对干预肿瘤的发生和发展有重要意义。     

Therapeutic Evaluation on Advanced Pancreatic Cancer Treated by Integrative Chinese and Western Medicine──Clinical Analysis of 56 Cases

Objective: In comparison with chemotherapy, to evaluate therapeutic effects on advanced pancreatic cancer treated by integrative Chinese and western medicine (ICWM) therapies. Methods: Based on the retrospective study of 56 patients with advanced pancreatic cancer, life table was applied to the analysis of patients' survival rate and Xz test to the comparison of therapeutic response between ICWM and chemotherapy groups. Results: The results showed that 1-year survival rate in the ICWM group was 55. 37%±3.24%; 2-year survival rate 34. 61%±16. 31%; 3-year survival rate 25. 96%±24. 64%; 5-year survival rate 25. 96%±24.64%; and median survival period 16. 3 months. However 1-year survival rate in the chemotherapy group was 21. 95%±27. 54% ; 2-year survival rate 7. 31%±27. 54% ; 3-year survival rate 0 % ; and median survival period 7. 5 months. The therapeutic effects between two groups were significantly different (P=0. 004). Further analysis suggested that the reduction of cancer mass in the ICWM grou
