Adding pharmacists to primary care teams reduces predicted long‐term risk of cardiovascular events in Type 2 diabetic patients without established cardiovascular disease: results from a randomized trial

Aim To determine the impact of adding pharmacists to primary care teams on predicted 10‐year risk of cardiovascular events in patients with Type 2 diabetes without established cardiovascular disease. Methods This was a pre‐specified secondary analysis of randomized trial data. The main study found that, compared with usual care, addition of a pharmacist resulted in improvements in blood pressure, dyslipidaemia, and hyperglycaemia for primary care patients with Type 2 diabetes. In this sub‐study, predicted 10‐year risk of cardiovascular events at baseline and 1 year were calculated for patients free of cardiovascular disease at enrolment. The primary outcome was change in UK Prospective Diabetes Study (UKPDS) risk score; change in Framingham risk score was a secondary outcome. Results Baseline characteristics were similar between the 102 intervention patients and 93 control subjects: 59% women, median (interquartile range) age 57 (50–64) years, diabetes duration 3 (1–6.5) years, systolic blood pressure 128 (120–140) mmHg, total cholesterol 4.34 (3.75–5.04) mmol/l and HbA_1c 54 mmol/mol (48–64 mmol/mol) [7.1% (6.5–8.0%)]. Median baseline UKPDS risk score was 10.2% (6.0–16.7%) for intervention patients and 9.5% (5.8–15.1%) for control subjects (P = 0.80). One‐year post‐randomization, the median absolute reduction in UKPDS risk score was 1.0% greater for intervention patients compared with control subjects (P = 0.032). Similar changes were seen with the Framingham risk score (median reduction 1.2% greater for intervention patients compared with control subjects, P = 0.048). The two risk scores were highly correlated (rho = 0.83; P < 0.001). Conclusion Adding pharmacists to primary care teams for 1 year significantly reduced the predicted 10‐year risk of cardiovascular events for patients with Type 2 diabetes without established cardiovascular disease.     

Three Meals a Day is Passé at Progressive Hospital

Modern medical simulation technology (MST) debuted in 1960 with the development of Resusci Annie (Laerdal 2007), which assisted students in the acquisition of proper ventilation and compression techniques used during basic life support. Following a steady stream of subsequent technological advances and innovations, MST manufacturers are now able to offer training aids capable of facilitating innovative learning in such diverse areas as human patient simulators, simulated clinical environments, virtual procedure stations, virtual medical environments, electronic tutors, and performance recording. The authors list a number of the most popular MSTs presently available while citing evaluative efforts undertaken to date regarding the efficacy of MST to the medical profession. They conclude by proposing a variety of simulation innovations of prospective interest to both medical and technology personnel while offering healthcare administrators a series of recommended considerations when planning to integrate MST into existing medical systems.     

超声对甲状腺术后瘢痕组织的诊断应用

甲状腺术后瘢痕组织是甲状腺局部分切除术后由于手术方式及缝线填充而形成的组织,甲状腺术后瘢痕组织形成及其发生发展过程同一般的组织损伤修复病理过程一样,为渐进老化阶段的结缔组织,其内小血管稀少,胶原纤维增多[1]。由于甲状腺术后瘢痕组织其质地较硬,活动性差,超声声像图上表现缺乏典型特征,与癌灶极其相似,因此鉴别较困难。本文将介绍超声对于甲状腺术后的随诊应用,分析甲状腺术后瘢痕组织的超声检查特点并着重介绍超声动态观察甲状腺术后瘢痕组织的应用及其发展前景。

Abstract：

Objective To summarize the experience and evaluate the efficacy of treatment of urethral stricture using direct visual internal urethrotomy (DVIU).Methods The clinical data of 361 patients (age range 16 -72 years, mean age 38 years) with urethral stricture who underwent urethrotomy from 1990 to 2010 was retrospectively analyzed.The disease course ranged from three months to 78 months with a mean of 16 months.The stricture length ranged from 0.2 to 2.0 cm (mean 1.1 cm).Stricture length was split into four main groups:stricture length≤0.5 cm in 63 (group 1 ), stricture length ranging between 0.6 and 1.0 cm in 175 ( group 2), stricture length ranging between 1.0 and 1.5 cm in 85 ( group 3 ) , and stricture length ranging between 1.6 and 2.0 cm in 38 ( Group 4).Of the 238 patients with length less than 1.0 cm there were 148 who's scar thickness were less than 1.0 cm, and 90 who's scar thickness were greater than 1.0 cm.Of the 123 patients with length less than 2.0 cm there were 69 who's scar thickness was less than 1.0 cm, and 54 who's scar thickness was greater than 1.0 cm.Results Three patients with DVIU failed because of long occlusion and false passage.Three hundred and twenty patients were followed-up from 12 to 120 months (mean:42).Re-openiag procedures were performed on 174 patients (54.4%) due to recurrence.The re-openiag procedure rate was 3.3%, 49.7%, 83.3% and 97.1% in Group1, Group2,Group3 and Group4, respectively.On the basis of scar thickness, of the 207 patients with stricture length less than 1.0 cm, 38 of 136 patients (27.9%) with scar thickness less than 1.0 cm underwent opening operation, and 43 of 71 patients (60.6%) with scar thickness more than 1.0 cm underwent opening operation.One hundred and thirteen patients with stricture length more than 1.0 cm, 33 of 42 patients (78.6%) with scar thickness less than 1.0 cm underwent opening operation, and 60 of 71 patients (84.5%) with scar thickness more than 1.0 cm underwent opening operation.Conclusions Good efficacy can be achieved in patients whose urethral stricture length is less than 0.5cm or whose stricture length and scar thickness is less than 1.0 cm using DVIU.     

Meta-analysis of retrojugular versus antejugular approach for carotid endarterectomy

Introduction

The retrojugular approach for carotid endarterectomy (CEA) has been reported to have the advantages of shorter operative time and ease of dissection, especially in high carotid lesions. Controversial opinion exists with regard to its safety and benefits over the conventional antejugular approach.

Methods

A systematic review of electronic information sources was conducted to identify studies comparing outcomes of CEA performed with the retrojugular and antejugular approach. Synthesis of summary statistics was undertaken and fixed or random effects models were applied to combine outcome data.

Findings

A total of 6 studies reporting on a total of 740 CEAs (retrojugular approach: 333 patients; antejugular approach: 407 patients) entered our meta-analysis models. The retrojugular approach was found to be associated with a higher incidence of laryngeal nerve damage (odds ratio [OR]: 3.21, 95% confidence interval [CI]: 1.46–7.07). No significant differences in the incidence of hypoglossal or accessory nerve damage were identified between the retrojugular and antejugular approach groups (OR: 1.09 and 11.51, 95% CI: 0.31–3.80 and 0.59–225.43). Cranial nerve damage persisting during the follow-up period was similar between the groups (OR: 2.96, 95% CI: 0.79–11.13). Perioperative stroke and mortality rates did not differ in patients treated with the retrojugular or antejugular approach (OR: 1.26 and 1.28, 95% CI: 0.31–5.21 and 0.25–6.50).

Conclusions

Currently, there is no conclusive evidence to favour one approach over the other. Proof from a well designed randomised trial would help determine the role and benefits of the retrojugular approach in CEA.     

柠檬酸对分化型甲状腺癌患者首次131I治疗后唾液腺功能的保护作用

目的：探讨柠檬酸对术后首次行¹³¹I治疗（简称清甲治疗）的分化型甲状腺癌（DTC）患者唾液腺功能的影响,阐明柠檬酸对¹³¹I治疗的甲状腺癌患者唾液腺功能的保护作用。方法：经患者知情同意,随机选择准备首次行¹³¹I治疗的68例甲状腺乳头状癌患者,随机分为对照组和柠檬酸组,每组34例。对照组患者无特殊准备,柠檬酸组患者于¹³¹I治疗前1周及治疗后3周内每天含柠檬酸1 min（0.2 g/次）后吐出。2组患者分别于¹³¹I治疗前24 h及¹³¹I治疗后3个月行2次^99mTcO^4-唾液腺显像检查,计算第15分钟摄取指数（15 min UI）和排泌分数（SR）,评估唾液腺功能。结果：与¹³¹I治疗前比较,对照组患者¹³¹I治疗后右侧腮腺和双侧颌下腺15 min UI差异无统计学意义（P>0.05）,左侧腮腺15 min UI降低（P<0.05）;与¹³¹I治疗前比较,柠檬酸组患者¹³¹I治疗后双侧腮腺及双侧颌下腺15 min UI差异无统计学意义（P>0.05）;与对照组比较,柠檬酸组患者¹³¹I治疗前后双侧腮腺和双侧颌下腺15 min UI差异均无统计学意义（P>0.05）。与¹³¹I治疗前比较,对照组患者双侧腮腺治疗后SR降低（P<0.05）,双侧颌下腺SR差异无统计学意义（P>0.05）,柠檬酸组患者双侧腮腺和双侧颌下腺治疗后SR差异无统计学意义（P>0.05）;与对照组¹³¹I治疗后比较,柠檬酸组患者双侧腮腺SR升高（P<0.05）,双侧颌下腺SR差异无统计学意义（P>0.05）。结论：DTC患者术后首次¹³¹I治疗后唾液腺排泌功能可能受损,短期口含柠檬酸对唾液腺具有保护作用,可以减轻唾液腺的放射性损伤。
