Treatment strategies for hypertension in patients with type 1 diabetes

ABSTRACT

Introduction

Type 1 diabetes mellitus (T1DM) is a chronic, autoimmune disease that is characterized by total absence of insulin production. Hypertension is a common comorbidity in T1DM with complex pathophysiology, while it is also a well-recognized risk factor for the development of cardiovascular disease (CVD), as well as other microvascular diabetic complications.     

A randomized study on the effect of modified behavioral activation treatment for depressive symptoms in rural left-behind elderly

Objective: To evaluate the effectiveness of a modified behavioral activation treatment (MBAT) intervention on reducing depressive symptoms in rural left-behind elderly.

Method: This is a randomized study registered in Chinese Clinical Trial Registry (ChiCTR-IOR-17011289). Eighty rural left-behind elderly people who had a Geriatric Depression Scale (GDS) score between 11 and 25 were randomly assigned to the intervention (n?=?40) and control group (n?=?40). The intervention group received both MBAT and regular treatment for 8 weeks while the control group received regular treatment. Both groups were assessed with the GDS, Beck Anxiety Inventory (BAI), and Oxford Happiness Questionnaire (OHQ) at baseline, immediately post-intervention, and at 3 months post-intervention.

Results: There were a total of 73 participants that completed the intervention. The scores of GDS and BAI decreased significantly, but the scores of OHQ increased significantly in the intervention group after 8 sessions of MBAT (P?<?.01). The reduction in depression symptoms after the intervention was maintained at the 3-month follow-up. Significant differences in GDS, BAI, and OHQ scores were observed between the intervention group and the control group (P?<?.01).

Conclusion: MBAT produced a significantly greater reduction in depressive symptoms than regular care in rural left-behind elderly.

Clinical or methodological significance of this article: A modified behavioral activation (BA) psychotherapy can significantly reduce the recurrence and seriousness of depression symptoms in the left-behind elderly with mild to moderate depression. This study also suggests that further study of the MBAT as an intervention will provide a direction for the management of mental health in rural left-behind elders.     

Effects of probiotics on gastrointestinal complications and nutritional status of postoperative patients with esophageal cancer: A protocol of randomized controlled trial

Background:Gastrointestinal complications and malnutrition are common problems that affect postoperative rehabilitation and survival of patients with esophageal cancer. Evidence has shown that probiotics have a positive effect on improving gastrointestinal complications and nutritional status of patients with esophageal cancer after surgery, but there is a lack of prospective studies on this topic. We designed this prospective randomized controlled trial to evaluate the effects of probiotics on gastrointestinal complications and nutritional status in patients with postoperative esophageal cancer.Methods:This is a prospective, randomized, double-blind, placebo-controlled trial. It was approved by the Clinical Research Ethics Committee of our hospital. 192 patients will be randomly divided into probiotics group and the placebo group in a 1:1 ratio. After operation, probiotics and placebo will be given orally for 8 weeks. The indexes of nutritional status and incidence of digestive tract complications will be recorded and the data will be analyzed by SPSS 18.0 software.Discussion:This study will evaluate the effect of probiotics on gastrointestinal complications and nutritional status of postoperative patients with esophageal cancer. The results of this study will provide clinical basis for the use of probiotics in postoperative treatment of esophageal cancer.Trial registration:OSF Registration number: D DOI 10.17605/OSF.IO/QHW86     

临床抗青光眼药物的新进展

青光眼是致盲的主要原因之一，构成视神经的神经节细胞轴突受到多种因素的损伤，其机制尚未完全明了。青光眼最重要的危险因素是眼压升高。由于青光眼的视神经损伤尚不能直接治疗，根据目前提供的唯一已知可治疗的危险因素，可以降低升高的眼压，而眼压与房水流出通道的功能息息相关。这些方面的药物均可以影响青光眼的进展。随着医疗技术的发展以及对青光眼发病机制认识的加深，新型抗青光眼药物也应运而生，为眼科医师提供新的选择。本文将对国内外新型抗青光眼药物从机制、药理特点及临床疗效等方面进行综述。     

血清窖蛋白-1在慢性阻塞性肺疾病相关肺动脉高压患者中的表达及意义

目的 研究血清窖蛋白-1 （Cav-1） 在慢性阻塞性肺疾病 （COPD） 相关肺动脉高压 （PAH） 患者中的表达及其意义。方法 选取稳定期COPD患者65例， 根据是否合并PAH分成COPD组 ［肺动脉收缩压 （PASP） ＜40 mmHg， 35例］ 及COPD-PAH组 （PASP ≥40 mmHg， 30例）。另选取在本院健康体检的志愿者30例作为对照组。对比各组基线资料、 动脉血气分析、 肺功能指标， 以及血清Cav-1、 白细胞介素 （IL） -6和肿瘤坏死因子-α （TNF-α） 的表达水平。绘制受试者工作特征 （ROC） 曲线， 评价Cav-1对COPD合并PAH的诊断价值。结果 COPD-PAH组与COPD组第一秒用力呼吸容积 （FEV1） /用力肺活量 （FVC）、 FEV1占预计值百分比 （FEV1%） 及氧分压 ［p （O2 ）］ 低于对照组， 而二氧化碳分压 ［p （CO2 ）］、 PASP均高于对照组 （P＜0.01）。COPD-PAH组p （O2 ） 低于COPD组， p （CO2 ）、 PASP均高于COPD 组 （P＜0.01）。对照组、 COPD组及COPD-PAH组Cav-1表达水平呈逐渐降低趋势， 而IL-6、 TNF-α表达水平呈逐渐升高趋势 （P＜0.01）。血清Cav-1诊断COPD合并PAH的ROC曲线下面积为0.902 （0.821～0.955）， 最佳截断值为 6.66 μg/L， 此时诊断敏感度为76.7%， 特异度为85.7%， 与多普勒超声诊断仪测量PASP结果比较一致性较好 （Kappa 值=0.627）。结论 血清Cav-1在COPD相关PAH患者表达明显下调， 可以作为预测COPD相关PAH的新型血清标志物。
