If the transform's transform() operation is synchronous and always enqueues output immediately, it never signals backpressure back to the writable side even when the downstream consumer is slow. This is a consequence of the spec design that many developers completely overlook. In browsers, where there's only a single user and typically only a small number of stream pipelines active at any given time, this type of foot gun is often of no consequence, but it has a major impact on server-side or edge performance in runtimes that serve thousands of concurrent requests.
日前，北京市医保局和北京市人社局联合发布通知，明确调整经皮穿刺静脉置管术等4项医疗服务价格项目，并将中心静脉导管等2项手术可收费耗材纳入基本医疗保险和工伤保险报销范围。通知自12月28日起执行。根据通知，调整的4项医疗服务价格项目包括经皮穿刺静脉置管术、静脉导管拔除术、植入式给药装置置入术和植入式给药装置取出术。纳入医保和工伤报销范围的包括中心静脉导管和化疗泵/植入式给药装置这2项手术可收费耗材。经皮穿刺股静脉置管术、经皮穿刺锁骨下静脉置管术两项现行相关医疗服务价格项目同步废止。通知要求，各公立医疗机构要严格按照价格政策规定和临床诊疗规范向患者提供服务并收取费用，不得收取未列明的费用。公立医疗机构要在服务场所显著位置通过多种方式公示医疗服务项目、价格及服务规范等内容，落实好住院费用清单等相关规定。新京报记者 叶红梅SourcePh" style="display:none"
