Complementary and alternative medical therapy utilization by people with chronic fatiguing illnesses in the United States

Background  

Chronic fatiguing illnesses, including chronic fatigue syndrome (CFS), pose a diagnostic and therapeutic challenge. Previous clinical reports addressed the utilization of health care provided to patients with CFS by a variety of practitioners with other than allopathic training, but did not examine the spectrum of complementary and alternative medicine (CAM) therapies used. This study was designed to measure CAM therapy use by persons with fatiguing illnesses in the United States population.     

Impact of Dissection after Drug-Coated Balloon Treatment of De Novo Coronary Lesions: Angiographic and Clinical Outcomes

PurposeDissection after plain balloon angioplasty is required to achieve adequate luminal area; however, it is associated with a high risk of vascular events. This study aimed to examine the relationship between non-flow limiting coronary dissections and subsequent lumen loss and long-term clinical outcomes following successful drug-coated balloon (DCB) treatment of de novo coronary lesions.Materials and MethodsA total of 227 patients with good distal flow (Thrombolysis in Myocardial Infarction flow grade 3) following DCB treatment were retrospectively enrolled and stratified according to the presence or absence of a non-flow limiting dissection. The primary endpoint was late lumen loss (LLL) at 6-month angiography, and the secondary endpoint was target vessel failure (TVF, a composite of cardiac death, target vessel myocardial infarction, target vessel revascularization, and target vessel thrombosis).ResultsThe cohort consisted of 95 patients with and 132 patients without a dissection. There were no between-group differences in LLL (90.8%) returning for angiography at 6 months (0.05±0.19 mm in non-dissection and 0.05±0.30 mm in dissection group, p=0.886) or in TVF (6.8% in non-dissection and 8.4% in dissection group, p=0.799) at a median follow-up of 3.4 years. In a multivariate analysis, the presence of dissection and its severity were not associated with LLL or TVF. Almost dissections (93.9%) were completely healed, and there was no newly developed dissection at 6-month angiography.ConclusionThe presence of a dissection following successful DCB treatment of a de novo coronary lesion may not be associated with an increased risk of LLL or TVF (Impact of Drug-coated Balloon Treatment in de Novo Coronary Lesion; {"type":"clinical-trial","attrs":{"text":"NCT04619277","term_id":"NCT04619277"}}NCT04619277).     

山紫菀与紫菀镇咳祛痰作用的实验研究

本实验对山紫菀(蹄叶橐吾Ligularia fischeri Turcz.)作了镇咳、祛痰作用的研究,并与紫菀(Aster tataricus L.)在同等条件下进行了比较,它们的浓缩水煎剂均有明显的祛痰作用,而无明显的镇咳作用,二者之间无显著性差异。它们的挥发油乳剂及水煎剂也均未表现出明显的镇咳作用。紫菀挥发油毒性大于山紫菀。     

Efficacy of misoprostol (twice daily dosage) in acute healing of duodenal ulcer

This study was undertaken to evaluate the efficacy of misoprostol taken twice daily for the healing of duodenal ulcer. Three hundred thirty patients with endoscopically proven duodenal ulcer participated in a multicenter, double-blind, controlled trial comparing placebo with misoprostol 200 μg and 400 μg twice daily for up to four weeks. Patient characteristics were similar in all three treatment groups. Ulcers were between 0.3 cm and 2.0 cm in length. Healing was determined by endoscopy at two weeks; if ulcers were not healed, endoscopy was repeated at four weeks. All patients were given Al(OH)₃ antacid (up to 54 meq a day) to be used as needed for pain. Healing rates at four weeks for a total of 280 evaluable patients in the three treatment groups were as follows: misoprostol 400 μg bid, 65.4%; misoprostol 200 μg bid, 52.9%; and placebo, 42.2%. Misoprostol 400 μg bid was superior to placebo (P=0.002) in healing ulcers. However, the healing rate for misoprostol 200 μg bid did not differ significantly from placebo. The percentage of nonsmokers who healed at four weeks was higher than that of smokers in both misoprostoltreatment groups, although the difference was not analyzed for statistical significance. There were no differences in antacid consumption or pain relief among the three experimental groups during the study. Diarrhea was the most common side effect but was mild and self-limiting, occurring in 8.9%, 5.9%, and 1.8% of the misoprostol 400 μg, 200 μg, and placebo groups, respectively. These results indicate that misoprostol 400 μg, 200 μg, and for four weeks is effective and safe for the treatment of duodenal ulcers.     

流行性脑脊髓膜炎的流行趋势变化与其疫苗接种

在过去几十年,随着疫苗的广泛使用,不同国家和区域引起流行性脑脊髓膜炎(简称流脑)病原体的血清群也发生了变迁。本文将脑膜炎球菌疫苗免疫接种、感染人群、不同区域和国家流脑的流行趋势及其内在机制研究进展进行综述,为进一步了解流脑流行趋势变化与其疫苗接种和后续制定免疫策略提供参考。     

国内外产科质量指标体系现状和启示

通过文献回顾,对世界卫生组织产科质量指标体系、英国产科质量指标体系、美国产科质量指标体系、欧洲围产期保健计划、丹麦产科质量指标体系及我国的产科质量指标体系现状进行总结。认为我国产科质量指标体系缺乏最佳的指标变化趋势及期望达到的目标值,缺少基于产科质量指标进行质量改进的研究和证据,尚无基于产科质量指标体系的信息化质控平台。对此,建议探索产科质量控制指标的适宜标准值,建立质量指标和医疗质量评价的关联性,拓展指标体系内涵,加快信息化建设。

1990—2019年中国高血清低密度脂蛋白胆固醇疾病负担趋势分析与预测

目的 描述和分析1990—2019年中国高血清低密度脂蛋白胆固醇（high LDL cholesterol,高LDL - C）疾病负担状况及变化趋势,并预测未来5年的疾病负担,为中国高LDL - C科学防控提供依据。方法 提取2019年全球疾病负担（GBD 2019）中因高LDL - C造成的死亡数、死亡率及DALYs等疾病负担指标,相关指标均采用GBD 2019全球标准人口进行年龄标准化,采用平均年度变化百分比（AAPC）分析率的变化趋势,并应用R 4.1.0对1990—2016年中国因高LDL - C造成的死亡率和DALYs率建立ARIMA模型和NNAR模型,用2017—2019年的数据来评价两模型的拟合效果,最后用拟合效果最好的模型预测2020—2024年中国高LDL - C死亡率和DALYs率。结果 1990—2019年中国高LDL - C造成的死亡率（AAPC = 3.1%,P＜0.05）和DALYs率（AAPC = 2.2%,P＜0.05）整体呈波动上升趋势;标化死亡率和DALYs率增长14.21%和0.56%,男女性别比范围分别为1.33～1.67和1.36～1.76,男性高于女性;年龄别疾病负担≥70岁人群远高于15～49岁和50～69岁群体;ARIMA（0,2,0）和NNAR（1,1）模型预测与实际趋势基本一致,前者预测值与实际值相对误差、均方根误差（RMSE）、平均绝对误差（MAE）以及平均绝对百分误差（MAPE）均较小,预测精度更好。 结论 中国高LDL - C造成的疾病负担呈逐渐上升趋势,在2020—2024年将继续上升。男性、高龄人群疾病负担更加沉重,应采取针对性措施进行干预。
