2019年重庆市30岁及以上人群归因于被动吸烟的肺癌疾病负担研究

目的 分析重庆市肺癌发病死亡和疾病负担归因于被动吸烟的情况,为开展肺癌防治提供建议。 方法 肺癌死亡个案数据来源于2019年重庆市肿瘤登记报告系统,被动吸烟率来自2013年重庆市慢性病及危险因素监测。计算人群归因危险度百分比(population attributable risk percent, PAR%)、被动吸烟导致的肺癌发病、死亡和疾病负担。采用Excel 2010与SPSS 25.0进行统计分析,率的比较采用χ²检验。 结果 2013年30岁及以上成年人被动吸烟率为52.37%。2019年重庆市30岁及以上人群肺癌发病率与标化发病率分别为118.44/10万与80.83/10万,死亡率与标化死亡率分别为96.51/10万、63.58/10万。肺癌发病率和死亡率归因于被动吸烟的PAR%分别为19.76和19.04,归因发病率与归因标化发病率分别为23.41/10万和16.34/10万,归因死亡率与归因标化死亡率分别为18.38/10万和12.40/10万。2019年重庆市30岁及以上肺癌早死所致寿命损失年率(years of life lost,YLL)、残疾所致寿命损失年率(years lived with disability,YLD)、调整伤残寿命损失年率(disability adjusted life year,DALY)分别为21.16‰、0.31‰、21.47‰,YLL率、YLD率、DALY率归因于被动吸烟的PAR%分别为21.16、19.76和20.49,归因YLL率为4.34‰,归因YLD率为0.06‰,归因DALY率为4.40‰。 结论 2019年重庆市30岁及以上人群肺癌发病率、死亡率、YLL率、DALY率高,被动吸烟率高,肺癌归因于被动吸烟的疾病负担重,应加强落实控烟工作。     

Surgical resection after neoadjuvant durvalumab and radiation is feasible and safe in non–small cell lung cancer: Results from a randomized trial

ObjectiveSeveral trials have recently reported the safety of pulmonary resection after neoadjuvant immunotherapy with encouraging major pathological response rates. We report the detailed adverse events profile from a recently conducted randomized phase II trial in patients with resectable non–small cell lung cancer treated with neoadjuvant durvalumab alone or with sub-ablative radiation.MethodsWe conducted a randomized phase II trial in patients with non–small cell lung cancer clinical stages I to IIIA who were randomly assigned to receive neoadjuvant durvalumab alone or with sub-ablative radiation (8Gyx3). Secondary end points included the safety of 2 cycles of preoperative durvalumab with and without radiation followed by pulmonary resection. Postoperative adverse events within 30 days were recorded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (version 4.0).ResultsSixty patients were enrolled and randomly assigned, with planned resection performed in 26 patients in each arm. Baseline demographics and clinical variables were balanced between groups. The median operative time was similar between arms: 128 minutes (97-201) versus 146 minutes (109-214) (P = .314). There was no 30- or 90-day mortality. Grade 3/4 adverse events occurred in 10 of 26 patients (38%) after monotherapy and in 10 of 26 patients (38%) after dual therapy. Anemia requiring transfusion and hypotension were the 2 most common adverse events. The median length of stay was similar between arms (5 days vs 4 days, P = .172).ConclusionsIn this randomized trial, the addition of sub-ablative focal radiation to durvalumab in the neoadjuvant setting was not associated with increased mortality or morbidity compared with neoadjuvant durvalumab alone.     

RNA sequencing steps toward the first line

• DNA is the sequence that codes for proteins.
• Messenger RNA is transcribed from the DNA sequence of genes and translated into protein.
• It can be difficult to predict how a change in the DNA sequence will affect messenger RNA and protein quantity and quality.
• DNA translocation changes can cause the joining of sequences from two different genes or different parts of the same gene.
• DNA sequencing is often used clinically to predict how DNA changes might affect proteins.
• Alternatively, RNA sequencing can be used as a more direct measure of the effect of DNA changes on the protein products.
• This sequencing is important for identifying changes in cancer that may indicate response to targeted therapy, prognosis, or diagnosis.

     

碘对比剂引起急性肾损伤的相关危险因素分析

目的探讨不同程度碘对比剂后急性肾损伤的危险因素及其转归预后。方法筛选2016年4月1日至2019年8月31日于重庆医科大学附属第三医院住院期间发生碘对比剂后急性肾损伤(PC-AKI)的患者,按照急性肾损伤分层标准将其分为非严重损伤组(A组)和严重损伤组(B组),从基本人口学资料、基础疾病、药物使用情况、转归预后等方面分析两组患者的特点及差异。结果 1 920例患者中发生PC-AKI者90例,其中A组72例(80.00%),B组18例(20.00%),B组中最终需肾脏替代治疗(血液透析)干预者11例(12.22%)。A组与B组间一般情况、基础肾功能、碘对比剂的使用以及联用肾毒性药物、静脉水化量等观察指标无统计学差异。B组合并慢性疾病者更多,其中冠心病(55.56%vs 29.17%)、心肌梗死(27.78%vs 5.56%)患病率差异具有统计学意义(P<0.05),行血液透析的患者第一诊断为心肌梗死者占45.45%。65.85%的患者在使用对比剂后10 d内肌酐仍高于基线,54.54%的透析患者在出院时仍需透析治疗,81.81%的透析患者出院时死亡或放弃治疗。结论合并冠心病、心肌梗死的患者更容易发生严重PC-AKI,当合并这些疾病的患者使用碘对比剂时,临床医师应密切关注其肾功能的变化。PC-AKI的肾功转归较差,发生PC-AKI后需透析治疗的患者往往预后不良。

Bypass Surgery or Stenting for Left Main Coronary Artery Disease in Patients With Diabetes

Background

The randomized EXCEL (Evaluation of XIENCE versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization) trial reported a similar rate of the 3-year composite primary endpoint of death, myocardial infarction (MI), or stroke in patients with left main coronary artery disease (LMCAD) and site-assessed low or intermediate SYNTAX scores treated with percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). Whether these results are consistent in high-risk patients with diabetes, who have fared relatively better with CABG in most prior trials, is unknown.
