Renal Denervation for Treatment of Cardiac Arrhythmias: State of the Art and Future Directions

Renal Denervation for Treatment of Cardiac Arrhythmias . It has now been more than a quarter of a century since modulation of the sympathetic nervous system was proposed for the treatment of cardiac arrhythmias of different origins. But it has also been some time since some of the early surgical attempts have been abandoned. With the development of ablation techniques, however, new approaches and targets have been recently introduced that have revolutionized our way of thinking about sympathetic modulation. Renal nerve ablation technology is now being successfully used for the treatment of resistant hypertension, but the indication spectrum might broaden and new therapeutic options might arise in the near future. This review focuses on the possible impact of renal sympathetic system modulation on cardiac arrhythmias, the current evidence supporting this approach, and the ongoing trials of this method in electrophysiological laboratories. We will discuss the potential roles that sympathetic modulation may play in the future.     

上海市黄浦区社会办医疗美容机构《医疗美容管理办法》知晓情况调查

目的了解上海市黄浦区社会办医疗美容机构的管理人员和医师对《医疗美容管理办法》相关内容的掌握情况,发现存在的问题并提出改善建议.方法采用现场调查与现场问卷调查相结合的方式,对在上海市黄浦区开展医疗美容科目的所有社会办医疗机构(共计38家)进行全覆盖现场调查,并对其中的管理人员41人、相关医师31人进行问卷调查.结果38家社会办医疗美容机构中,美容外科和美容皮肤科的开展率较高,分别为96.8%和97.2%,而美容牙科开展率为52.4%,美容中医科开展率最低(25.0%).管理人员关于非主诊医师可在主诊医师指导下工作的知晓率仅68.3%.关于美容外科、皮肤科、中医科、牙科主诊医师应具备的工作年限,管理人员答对率为90.2%,医师答对率为72.0%,二者有显著性差异(P<0.05).结论社会办医疗美容机构中的二级科目设置需进一步优化,以减少资源空置.应加强对医疗机构管理人员和医师的法律培训,改变经营模式,制定明确的准入与退出机制,从而减少违法违规行为的发生.

High-definition optical magnification with digital chromoendoscopy detects gastric mucosal changes in dyspeptic-patients

BACKGROUND Accurate detection of gastric infection by Helicobacter pylori(H.pylori) and premalignant lesions are important for effective provision of treatment,preventing the development of gastric neoplasia.Optical enhancement systems with optical magnification improved the identification of mucosal superficial and vascular patterns in patients with dyspepsia.AIM To evaluate an optical enhancement system with high-definition magnification,for diagnosis of normal gastric mucosa,H.pylori-associated gastritis,and gastric atrophy.METHODS A cross-sectional,nonrandomized study from November 2015 to April 2016 performed in a single-tertiary academic center from Ecuador.Seventy-two consecutive patients with functional dyspepsia according to the Rome III criteria,were tested for H.pylori using a stool antigen test and were assigned to an Hp+group or an Hp-control group.Esophagogastroduodenoscopy with highdefinition optical magnification and digital chromoendoscopy was performed,and patients were classified into 4 groups,in accordance to the microvasculararchitecture pattern of the mucosa.Interobserver and intraobserver agreement among operators were calculated.RESULTS Of the 72 participants,35 were Hp+ and 37 were Hp-.Among 10 patients with normal mucosal histology in biopsy samples,90% had a Type I pattern of microvascular architecture by endoscopy.Among participants with type IIa and type IIb patterns,significantly more were Hp+ than Hp-(32 vs 8),and most(31 out of 40) had histological diagnoses of chronic active gastritis.Two of the three participants with a histological diagnosis of atrophy had a type III microvascular pattern.The type I pattern predicted normal mucosa,type IIa–IIb predicted H.pylori infection,and type III predicted atrophy with sensitivities of 90.0%,91.4%,and 66.7%,respectively.The intraobserver and interobserver agreements had kappa values of 0.91 and 0.89,respectively.CONCLUSION High-definition optical magnification with digital chromoendoscopy is useful for diagnosis of normal gastric mucosa and H.pylori-associated gastritis with high accuracy,but further studies are needed to determine whether endoscopic diagnosis of gastric atrophy is feasible.
