    背景:关于溃疡性结肠炎(UC)在诱导和维持期间批准的治疗方法的相对有效性和安全性的证据,包括upadacitinib(UPA),维多珠单抗(VEDO),ustekinumab(UST),和托法替尼(TOFA),是有限的。
    方法:使用来自3期试验的数据,UPA与VEDO的疗效和安全性的三个安慰剂(PBO)锚定匹配调整的间接比较,UST,和TOFA(U-成就和U-成就,GEMINI-1联合国,和OCTAVE诱导和维持试验)已经进行。分别对来自UPA试验的基线特征进行加权以匹配每个比较试验。诱导反应者被重新随机分配到口服UPA15或30毫克,VEDO300mg静脉注射每8周(Q8W),UST90毫克SCQ8W,或口服TOFA5毫克,或PBO在维护。第44周(UST)/46周(VEDO)/52周(UPA/TOFA)的疗效结局根据诱导反应的可能性进行调整,并包括临床反应,临床缓解,和内窥镜改进。安全性结果包括不良事件(AE),严重不良事件(SAE),以及导致停药的不良事件(UPA与VEDO)。获益-风险通过需要治疗的数字(NNT)/伤害来评估,计算为达到UPA疗效/安全性结果的患者比例与比较者的差异的倒数。
    结果:UPA15mg与VEDO和TOFA相比,表现出临床反应或内镜改善的患者比例更高(p<0.05)。UPA30mg与VEDO相比,显示所有治疗效果结果的患者比例明显更高,UST,或具有NNTs3.2-8.7的TOFA。AE的比例没有显着差异,SAEs,在两种剂量的UPA和比较物之间观察到导致停药的AE。
    结论:在活动性UC患者中,更大的临床疗效,UPA与VEDO在维持1年后观察到相似的安全性,UST,TOFA,为UPA提出有利的收益-风险状况。尽管匹配的基线特征,试验设计和终点的差异可能仍然存在.
    BACKGROUND: Evidence on the comparative efficacy and safety of approved therapies for ulcerative colitis (UC) during induction and maintenance, including upadacitinib (UPA), vedolizumab (VEDO), ustekinumab (UST), and tofacitinib (TOFA), is limited.
    METHODS: Using data from phase 3 trials, three placebo (PBO)-anchored matching-adjusted indirect comparisons of the efficacy and safety of UPA versus VEDO, UST, and TOFA (U-ACHIEVE and U-ACCOMPLISH, GEMINI-1, UNIFI, and OCTAVE induction and maintenance trials) have been conducted. Baseline characteristics from UPA trials were weighted separately to match each comparator trial. Induction responders were re-randomized to oral UPA 15 or 30 mg, VEDO 300 mg intravenously every 8 weeks (Q8W), UST 90 mg SC Q8W, or oral TOFA 5 mg, or PBO in maintenance. Treat-through efficacy outcomes at weeks 44(UST)/46(VEDO)/52(UPA/TOFA) were adjusted by the likelihood of induction response and included clinical response, clinical remission, and endoscopic improvement. Safety outcomes included adverse events (AEs), serious AEs (SAEs), and AEs leading to discontinuation (except UPA vs. VEDO). Benefit-risk was assessed by numbers needed to treat (NNT)/harm, calculated as the inverse of the difference in proportions of patients achieving each efficacy/safety outcome for UPA versus comparator.
    RESULTS: The proportions of patients who demonstrated clinical response or endoscopic improvement was greater with UPA 15 mg versus VEDO and TOFA (p < 0.05). The proportions of patients demonstrating all treat-through efficacy outcomes were significantly greater with UPA 30 mg versus VEDO, UST, or TOFA with NNTs 3.2-8.7. No significant differences in proportions of AEs, SAEs, and AEs leading to discontinuation were observed between the two doses of UPA and comparators.
    CONCLUSIONS: In patients with active UC, greater clinical efficacy, and similar safety after 1 year of maintenance were observed with UPA versus VEDO, UST, and TOFA, suggesting a favorable benefit-risk profile for UPA. Despite matched baseline characteristics, differences in trial design and endpoints may persist.

    克拉屈滨与其他有效的多发性硬化症(MS)免疫疗法之间的比较缺乏。
    为了比较克拉屈滨与芬戈莫德的疗效,那他珠单抗,奥克瑞珠单抗和阿仑珠单抗治疗复发缓解型MS。
    接受克拉屈滨治疗的复发缓解型MS患者,芬戈莫德,那他珠单抗,在全球MSBase队列和另外两个英国中心中发现了奥克瑞珠单抗或阿仑珠单抗.患者被跟踪6/12,并有3个人残疾评估。使用倾向评分对患者进行匹配。四个成对分析比较了年复发率(ARR)和残疾结果。
    符合条件的队列包括853(芬戈莫德),464(那他珠单抗),1131(奥克雷珠单抗),123例(阿仑单抗)或493例(克拉屈滨)患者。克拉屈滨的ARR低于芬戈莫德(0.07vs.0.12,p=0.006),ARR高于那他珠单抗(0.10vs.0.06,p=0.03),奥克瑞珠单抗(0.09vs.0.05,p=0.008)和阿仑珠单抗(0.17vs.0.04,p<0.001)。与克拉屈滨相比,使用芬戈莫德(风险比(HR)1.08,95%置信区间(CI)0.47-2.47)或阿仑珠单抗(HR0.73,95%CI0.26-2.07)治疗的患者的残疾恶化风险没有差异,但在接受那他珠单抗(HR0.35,95%CI0.13-0.94)和奥克瑞珠单抗(HR0.45,95%CI0.26-0.78)治疗的患者中更低.没有证据表明残疾改善有差异。
    克拉屈滨是一种有效的治疗方法,可以看作是芬戈莫德的有效性提高,但效果不如最有效的静脉MS疗法。
    UNASSIGNED: Comparisons between cladribine and other potent immunotherapies for multiple sclerosis (MS) are lacking.
    UNASSIGNED: To compare the effectiveness of cladribine against fingolimod, natalizumab, ocrelizumab and alemtuzumab in relapsing-remitting MS.
    UNASSIGNED: Patients with relapsing-remitting MS treated with cladribine, fingolimod, natalizumab, ocrelizumab or alemtuzumab were identified in the global MSBase cohort and two additional UK centres. Patients were followed for ⩾6/12 and had ⩾3 in-person disability assessments. Patients were matched using propensity score. Four pairwise analyses compared annualised relapse rates (ARRs) and disability outcomes.
    UNASSIGNED: The eligible cohorts consisted of 853 (fingolimod), 464 (natalizumab), 1131 (ocrelizumab), 123 (alemtuzumab) or 493 (cladribine) patients. Cladribine was associated with a lower ARR than fingolimod (0.07 vs. 0.12, p = 0.006) and a higher ARR than natalizumab (0.10 vs. 0.06, p = 0.03), ocrelizumab (0.09 vs. 0.05, p = 0.008) and alemtuzumab (0.17 vs. 0.04, p < 0.001). Compared to cladribine, the risk of disability worsening did not differ in patients treated with fingolimod (hazard ratio (HR) 1.08, 95% confidence interval (CI) 0.47-2.47) or alemtuzumab (HR 0.73, 95% CI 0.26-2.07), but was lower for patients treated with natalizumab (HR 0.35, 95% CI 0.13-0.94) and ocrelizumab (HR 0.45, 95% CI 0.26-0.78). There was no evidence for a difference in disability improvement.
    UNASSIGNED: Cladribine is an effective therapy that can be viewed as a step up in effectiveness from fingolimod, but is less effective than the most potent intravenous MS therapies.

    局部和局部前列腺癌的治疗包括积极监测,放射治疗(RT),和根治性前列腺切除术(RP)。基于人群的研究将RP与辐射进行比较,由于方法上的缺陷,结果相互矛盾。这项系统综述和汇总分析的研究旨在比较特定原因的生存率(CSS),总生存期(OS),无病生存率(DFS)和毒性结局,比较RP和RT在前列腺癌的治疗。这个系统的评论搜索包括PubMed,Embase,和Cochrane库,根据PRISMA声明,每个数据库的开始时间为2023年6月24日。包括在前列腺癌中比较RP与RT的随机2期或3期临床试验。使用Mantel-Haenszel方法绘制了赔率比(OR)的森林地块,Z检验用于评估显著性。采用固定效应模型进行Meta分析。该搜索产生了7个已完成的随机临床试验和4个正在进行的试验。大多数完整的试验有低至中等风险的患者人群。OS的OR为1.00,95%CI为0.71-1.41(P值:0.98),CSSOR为0.99,95%CI为0.45-2.18(P值0.11),当RP与RT比较时,DFS的OR为1.26,95%CI为0.89-1.78(P值0.19)。在10年时,RP的远处转移疾病的发生率为2.3%,而RT的发生率为2.9%。在10年时,RP中第二恶性肿瘤的发生率为4.5%,而RT组中为4.2%。RP引起更多的泌尿症状,主要需要尿垫和性功能障碍的发生率较高,RT导致肠道症状的发生率更高,如粪便中的血和大便失禁。这项研究提供的证据表明,当比较RP与RT时,低风险至中危前列腺癌患者的治疗相关结果相似。多学科治疗方法和考虑患者的价值观和偏好应该成为每位局限性前列腺癌患者理想治疗选择的基石。患有前列腺癌的患者在RP或RT下10年时无癌和存活的机会相等。在副作用方面,RP会导致更多的尿液泄漏和勃起损失,而RT往往会引起更多的肠道副作用,如粪便中的血液和粪便渗漏。
    The treatment landscape for localized and regional prostate cancer includes active surveillance, radiation therapy (RT), and radical prostatectomy (RP). Population-based studies comparing RP to radiation reveal conflicting results due to methodological flaws. This systematic review and pooled analysis of studies aim to compare cause-specific survival (CSS), overall survival (OS), disease-free survival (DFS) and toxicity outcomes, comparing RP to RT in the management of prostate cancer. This systematic review search included the PubMed, Embase, and Cochrane libraries according to the PRISMA statement with the inception of each database up to June 24, 2023. Randomized phase 2 or 3 clinical trials that compared RP to RT in prostate cancer were included. The forest plot for the Odds ratio (OR) was plotted using the Mantel-Haenszel method, and the Z test was used to assess significance. A fixed effects model was used for meta-analysis. The search yielded seven completed randomized clinical trials and four ongoing trials. The majority of complete trials had low to intermediate-risk patient populations. OR for OS was 1.00 with 95% CI, 0.71-1.41 (P-value: 0.98), CSS OR was 0.99 with 95% CI, 0.45-2.18 (P-value 0.11), OR for DFS was 1.26 with 95% CI, 0.89-1.78 (P-value 0.19) when comparing RP to RT. The rate of distant metastatic disease was 2.3% in the RP versus 2.9% in the RT at 10 years. The rate of second malignant neoplasms was 4.5% in the RP compared to 4.2% in the RT arm at 10 years. RP caused more urinary symptoms, with a predominance of the need for urinary pads and a higher incidence of sexual dysfunction, and RT caused a higher incidence of bowel symptoms, such as blood in stools and fecal incontinence. This study provides evidence that the treatment-related outcomes are similar in patients with low to intermediate-risk prostate cancer when comparing RP to RT. Multidisciplinary treatment approaches and factoring patients\' values and preferences should form the cornerstone of the ideal treatment option for each patient with localized prostate cancer. Patients with prostate cancer have an equal chance of being cancer-free and alive at 10 years with either RP or RT. In terms of side effects, RP causes more urine leakage and loss of erections, whereas RT tends to cause more bowel side effects, such as blood in stools and fecal leakage.

    背景:肿瘤学中的一些治疗策略问题可以通过使用观察数据的研究来回答。目标试验仿真是将随机对照试验的设计原则应用于观察数据的分析,减少设计引起的偏差。我们的目标是确定哪种类型的研究医生最好计划回答肿瘤学中缺乏证据的比较有效性问题。
    方法:我们在肿瘤学专业医师中发起了一项在线调查。我们构建了一个基于小插图的查询,其中小插图描述了可以用来回答预定义问题的研究方案。我们设计了六个由研究设计描述的小插曲(随机对照试验或具有试验仿真框架的观察性研究),主要研究特点,研究成功的概率和在结果可用之前的预期延迟。参与者随机评估了5个小插曲的成对比较,并被问及他们最好使用李克特量表计划哪个研究。主要结果是评估临床医生对每个成对比较的偏好。计算平均和中位数偏好评分。
    结果:213名参与者,专门研究许多肿瘤类型,评估了至少一个比较,82%的人报告法国是他们的隶属国。在成对比较中,四分位间距为-4到4。对于出现的五个比较,中位数偏好评分不利于单中心随机对照试验。与单中心仿真试验4[IQ2.5-4]相比,中位数偏好评分强烈支持多中心国家仿真试验。在大型欧洲观察研究1.14(SD3.33)中,平均偏好得分最高,而单中心随机对照试验的平均偏好评分最低-1.86(SD2.93).
    结论:没有研究设计是强烈的首选,但是单中心随机对照试验是配对比较中最不受欢迎的研究.新研究的平面化是科学健全性之间的折衷,可行性,成本,以及获得结果之前的时间。我们需要在正确的时间对正确的问题有正确的答案。
    BACKGROUND: Some therapeutic strategy questions in oncology could be answered with studies using observational data. Target trial emulation is the application of design principles from randomized controlled trials to the analysis of observational data, to reduce design-induced biases. Our objective was to determine which type of study physicians would preferably plan to answer a comparative effectiveness question lacking evidence in oncology.
    METHODS: We launched an online survey among physicians specialized in oncology. We constructed a vignette-based inquiry where vignettes described study scenarios which could be conducted to answer the predefined question. We designed six vignettes described by study design (randomized controlled trial or observational study with a trial emulation framework), main study characteristics, probability of the study succeeding and anticipated delay before results availability. Participants randomly assessed five pair-wise comparisons of the vignettes and were asked which study they would preferably plan by using a Likert scale. The main outcome was the evaluation of clinicians\' preferences for each pairwise comparison. Mean and median preference scores were calculated.
    RESULTS: 213 participants, specialized in many tumor types, assessed at least one comparison with 82% reporting France as their country of affiliation. The interquartile range was -4 to 4 across pairwise comparisons. The median preference score was in disfavor of the monocentric randomized controlled trial for the five comparisons where it appeared. The median preference score was strongly in favor of the multicentric national emulated trial when compared to the monocentric emulated trial 4 [IQ 2.5-4]. The mean preference score was the highest for the large European observational study 1.14 (SD 3.33), while the mean preference score was the lowest for the monocentric randomized controlled trial -1.86 (SD 2.93).
    CONCLUSIONS: No study design was strongly preferred, but the monocentric randomized controlled trial was the least favored study in pair-wise comparisons. The planification of the new research is a compromise between scientific soundness, feasibility, cost, and time before obtaining results. We need to have the right answers to the right questions at the right time.

    尽管持有承诺,在严重青光眼中使用MIGS的报道很少,并且没有描述在该人群中合并多个MIGS。据我们所知,这是报道严重青光眼患者超声乳化术和MIGS(Phaco/MIGS)结局的最大研究.
    这项回顾性研究包括327例严重青光眼患者的临床就诊,这些患者接受了Phaco/MIGS和iStent,内圈破坏,KahookDualBlade,Hydrus微支架,或这些MIGS(cMIGS)的组合在2016年至2021年之间进行。主要结果包括通过广义估计方程评估的眼内压(IOP)和药物负担,以及卡普兰-迈耶估计。进一步分析比较了cMIGS和单一Phaco/MIGS(sMIGS)的疗效,程序持续时间,视敏度,和并发症。
    术前平均IOP为16.7mmHg±5.8(SD),总体使用2.3±1.9药物(N=71),sMIGS组的1.7±1.9药物为16.9±6.3mmHg(N=37),cMIGS组的2.9±1.6药物治疗为16.4±5.3mmHg(N=34)。在整个12个月中,Phaco/MIGS导致IOP(p<0.001)和药物(p=0.03)的显着降低模式。12个月时,47.5%,87.5%,64.7%的患者达到IOP≤12mmHg,17mmHg,或预定的目标IOP,分别,没有额外的药物或程序。1.8±1.7药物的平均12个月IOP为13.5±3.1mmHg。在调整基线药物负担后,cMIGS和sMIGS的眼压降低模式(p<0.05)不同,赞成cMIGS,两组患者的用药减少模式相似(p=0.75).
    在白内障和严重青光眼患者中使用Phaco/MIGS可以显着降低整个12个月的IOP和药物负担,因此,在进行更具侵入性的青光眼手术之前,可以作为患有视觉上明显的白内障的严重青光眼患者的垫脚石。cMIGS的组合效应可以增强这种效应。
    许多接受白内障手术的白内障和轻度或中度青光眼患者也受益于同时进行的微创青光眼手术(MIGS),但是MIGS在严重青光眼和白内障患者中的作用尚不清楚。我们报告说,合并白内障手术和MIGS与严重青光眼患者超过12个月的眼压显着降低有关。
    UNASSIGNED: Despite holding promise, reports of using MIGS in severe glaucoma are scarce, and none has described combining multiple MIGS in this population. To the best of our knowledge, this is the largest study to report outcomes of phacoemulsification and MIGS (Phaco/MIGS) in patients with severe glaucoma.
    UNASSIGNED: This retrospective review comprised 327 clinical visits of 71 patients with severe glaucoma who underwent Phaco/MIGS with iStent, endocyclodestruction, Kahook Dual Blade, Hydrus Microstent, or a combination of these MIGS (cMIGS) performed between 2016 and 2021. Primary outcomes included intraocular pressure (IOP) and medication burden evaluated by Generalized Estimating Equations, as well as Kaplan-Meier Estimates. Further analyses compared the efficacy of cMIGS and single Phaco/MIGS (sMIGS), procedure duration, visual acuity, and complications.
    UNASSIGNED: Mean preoperative IOP was 16.7 mmHg ± 5.8 (SD) on 2.3 ± 1.9 medications overall (N = 71), 16.9 ± 6.3 mmHg on 1.7 ± 1.9 medications in the sMIGS group (N = 37), and 16.4 ± 5.3 mmHg on 2.9 ± 1.6 medications in the cMIGS group (N = 34). Throughout 12 months, Phaco/MIGS led to significant reduction patterns in IOP (p < 0.001) and medications (p = 0.03). At 12 months, 47.5%, 87.5%, and 64.7% of the patients achieved IOP ≤ 12 mmHg, 17 mmHg, or predetermined goal IOP, respectively, without additional medication or procedure. Mean 12-month IOP was 13.5 ± 3.1 mmHg on 1.8 ± 1.7 medications. After adjusting for baseline medication burden, the reduction pattern in IOP (p < 0.05) was different between cMIGS and sMIGS, favoring cMIGS, and the groups had similar reduction patterns in medications (p = 0.75).
    UNASSIGNED: The use of Phaco/MIGS in patients with cataract and severe glaucoma may significantly reduce IOP and medication burden throughout 12 months and, thus, may serve as a stepping stone in severe glaucoma patients with visually significant cataract before proceeding with more invasive glaucoma surgery. This effect may be potentiated by the combination effect of cMIGS.
    Many patients with cataract and mild or moderate glaucoma who undergo cataract surgery also benefit from microinvasive glaucoma surgery (MIGS) performed at the same time, but the role of MIGS in patients with severe glaucoma and cataract is not clear. We report that combined cataract surgery and MIGS were associated with significant reductions in eye pressure in patients with severe glaucoma for more than 12 months.

    缺乏比较Venetoclax和Bruton酪氨酸激酶抑制剂(BTKis)在一线(1L)慢性淋巴细胞白血病(CLL)患者中的临床结果的现实证据。我们比较了1Lvenetoclax联合obinutuzumab(VenO)与基于BTKi的方案的治疗效果。这项使用OptumClinformaticsDataMart®的回顾性观察性研究包括在1L(1/2019-9/2022)中接受基于VenO或BTKi的方案的CLL成年患者(≥2名门诊或≥1名住院患者)。使用稳定的逆概率加权来平衡基线特征。结果包括治疗持续时间(DoT),持久性,下一次治疗或死亡的时间(TTNT-D),和时间离开治疗。在1506名符合条件的患者中(VenO:203;BTKi:1303),中位随访时间为12.6个月(VenO)和16.2个月(BTKi).VenO的平均DoT为12.3个月;通过预期的1L固定治疗持续时间,VenO的持久性仍高于BTKi。VenO未达到TTNT-D的中位数;然而,与BTKi相比,接受VenO治疗的患者在第12个月内没有转换治疗/经历死亡(87.1%与75.3%)。在停药的患者中,中位停药时间为11.7vs.VenO与BTKi的5.9个月,中位治疗时间为11.3vs.4.3个月。在现实世界的研究中,在1LCLL中,与基于BTKi的方案相比,VenO与更好的疗效结果相关。
    Real-world evidence comparing clinical outcomes between venetoclax and Bruton tyrosine kinase inhibitors (BTKis) in patients with frontline (1 L) chronic lymphocytic leukaemia (CLL) is lacking. We compared treatment effectiveness of 1 L venetoclax plus obinutuzumab (VenO) versus BTKi-based regimens. This retrospective observational study using Optum Clinformatics Data Mart® included adult patients with CLL (≥2 outpatient or ≥1 inpatient claim) who received VenO or BTKi-based regimens in 1 L (1/2019-9/2022). Baseline characteristics were balanced using stabilised inverse probability weighting. Outcomes included duration of therapy (DoT), persistence, time to next treatment or death (TTNT-D), and time off-treatment. Among 1506 eligible patients (VenO: 203; BTKi: 1303), the median follow-up duration was 12.6 (VenO) and 16.2 months (BTKi). Median DoT for VenO was 12.3 months; persistence remained higher in VenO versus BTKi through expected 1 L fixed treatment duration. Median TTNT-D was not reached for VenO; however, more VenO- versus BTKi-treated patients had not switched therapies/experienced death through Month 12 (87.1% vs. 75.3%). Among patients that discontinued, median time to discontinuation was 11.7 vs. 5.9 months for VenO versus BTKi and median time off-treatment was 11.3 vs. 4.3 months. In this real-world study, VenO was associated with better effectiveness outcomes than BTKi-based regimens in 1 L CLL.

    背景:患有房颤的疗养院居民有缺血性卒中的高风险,但大多数没有抗凝剂治疗。这项研究比较了口服抗凝剂(OAC)使用者和非使用者之间的有效性和安全性。
    方法:我们使用与医疗保险索赔相关的最低数据集3.0评估进行了一项新用户回顾性队列研究。参与者是2011年至2016年间居住在美国疗养院的患有房颤的Medicare服务付费受益人,年龄≥65岁。主要结局是缺血性卒中或全身性栓塞的发生(有效性),颅内或颅外出血的发生(安全性)和净临床结果(有效性或安全性结果)。次要结局包括总死亡率和净临床和死亡率结局。Cox比例风险以及精细和灰色模型估计了多变量调整后的风险比(aHRs)和子分布风险比(sHRs)。
    结果:结果率很低(有效性:OAC:0.86;非使用者:1.73;安全性:OAC:2.26;非使用者:1.75(每100人年))。使用OAC与较低的有效性结果相关(sHR:0.69;95%置信区间(CI):0.61-0.77),较高的安全性(sHR:1.70;95%CI:1.58-1.84)和净临床结局(sHR:1.20;95%CI:1.13-1.28)较低的全因死亡率结局(sHR:0.60;95%CI:0.59-0.61),净临床结局和死亡率较低(sHR:0.60;95%CI:0.59-0.61)。华法林用户,但不是DOAC用户,与OAC非使用者相比,净临床结局率更高。
    结论:我们的结果支持OAC治疗预防缺血性卒中和延长寿命的益处。同时强调需要权衡明显的益处和增加的出血风险。结果与DOAC与华法林的净好感度一致。
    BACKGROUND: Nursing home residents with atrial fibrillation are at high risk for ischemic stroke, but most are not treated with anticoagulants. This study compared the effectiveness and safety between oral anticoagulant (OAC) users and non-users.
    METHODS: We conducted a new-user retrospective cohort study by using Minimum Data Set 3.0 assessments linked with Medicare claims. The participants were Medicare fee-for-service beneficiaries with atrial fibrillation residing in US nursing homes between 2011 and 2016, aged ≥ 65 years. The primary outcomes were occurrence of an ischemic stroke or systemic embolism (effectiveness), occurrence of intracranial or extracranial bleeding (safety) and net clinical outcome (effectiveness or safety outcomes). Secondary outcomes included total mortality and a net clinical and mortality outcome. Cox proportional hazards and Fine and Grey models estimated multivariable adjusted hazard ratios (aHRs) and sub-distribution hazard ratios (sHRs).
    RESULTS: Outcome rates were low (effectiveness: OAC: 0.86; non-users: 1.73; safety: OAC: 2.26; non-users: 1.75 (per 100 person-years)). OAC use was associated with a lower rate of the effectiveness outcome (sHR: 0.69; 95% Confidence Interval (CI): 0.61-0.77), higher rates of the safety (sHR: 1.70; 95% CI: 1.58-1.84) and net clinical outcomes (sHR: 1.20; 95% CI: 1.13-1.28) lower rate of all-cause mortality outcome (sHR: 0.60; 95% CI: 0.59-0.61), and lower rate of the net clinical and mortality outcome (sHR: 0.60; 95% CI: 0.59-0.61). Warfarin users, but not DOAC users, had a higher rate of the net clinical outcome versus OAC non-users.
    CONCLUSIONS: Our results support the benefits of treatment with OACs to prevent ischemic strokes and increase longevity, while highlighting the need to weigh apparent benefits against elevated risk for bleeding. Results were consistent with net favorability of DOACs versus warfarin.

    在患有稳定性缺血性心脏病的患者中,没有证据表明血运重建治疗时机对重复手术的需要有影响.我们旨在确定在医生建议的时间后接受冠状动脉旁路移植术的患者与及时经皮冠状动脉介入治疗的患者相比,重复血运重建是否存在差异。
    我们确定了25,520名60岁或以上的不列颠哥伦比亚省居民首次接受非紧急血运重建血管造影检查,2001年1月1日至2016年12月31日期间稳定的左主干或多支血管缺血性心脏病。我们估计了重复血运重建的未调整和调整的累积发生率函数,在死亡作为竞争风险的情况下,对接受延迟冠状动脉旁路移植术的患者进行指数血运重建或最后阶段经皮冠状动脉介入治疗后,与及时经皮冠状动脉介入治疗相比。
    用治疗权重的逆概率进行调整后,三年后,与接受及时经皮冠状动脉介入治疗的患者相比,接受延迟冠状动脉旁路移植术的患者重复血运重建的累积发生率显着降低(4.84%延迟冠状动脉旁路移植术,12.32%及时经皮冠状动脉介入治疗;亚分布风险比,0.16,95%CI,0.04-0.65)。
    接受延迟冠状动脉旁路移植术的患者重复血运重建的累积发生率低于接受及时经皮冠状动脉介入治疗的患者。希望等待接受冠状动脉旁路移植术的患者将看到较低重复血运重建的益处,而经皮冠状动脉介入治疗不受治疗延迟的影响。
    UNASSIGNED: In patients with stable ischemic heart disease, there is no evidence for the effect of revascularization treatment timing on the need for repeat procedures. We aimed to determine if repeat revascularizations differed among patients who received coronary artery bypass graft surgery after the time recommended by physicians compared with those who had timely percutaneous coronary intervention.
    UNASSIGNED: We identified 25,520 British Columbia residents 60 years or older who underwent first-time nonemergency revascularization for angiographically proven, stable left main or multivessel ischemic heart disease between January 1, 2001, and December 31, 2016. We estimated unadjusted and adjusted cumulative incidence functions for repeat revascularization, in the presence of death as a competing risk, after index revascularization or last staged percutaneous coronary intervention for patients undergoing delayed coronary artery bypass grafting compared with timely percutaneous coronary intervention.
    UNASSIGNED: After adjustment with inverse probability of treatment weights, at 3 years, patients who underwent delayed coronary artery bypass grafting had a statistically significant lower cumulative incidence of a repeat revascularization compared with patients who received timely percutaneous coronary intervention (4.84% delayed coronary artery bypass grafting, 12.32% timely percutaneous coronary intervention; subdistribution hazard ratio, 0.16, 95% CI, 0.04-0.65).
    UNASSIGNED: Patients who undergo delayed coronary artery bypass grafting have a lower cumulative incidence of repeat revascularization than patients who undergo timely percutaneous coronary intervention. Patients who want to wait to receive coronary artery bypass grafting will see the benefit of lower repeat revascularization over percutaneous coronary intervention unaffected by a delay in treatment.

    目的:随机对照试验(RCTs)是评价癌症新疗法疗效和安全性的金标准。然而,将患者纳入临床试验的控制组可能对罕见癌症具有挑战性,特别是在精确肿瘤学和靶向治疗的背景下。外部控制臂(ECA)是解决临床研究设计中这些挑战的潜在解决方案。我们进行了范围审查,以探讨ECA在肿瘤学中的应用。
    方法:我们系统地检索了四个数据库,即MEDLINE,EMBASE,WebofScience,还有Scopus.我们筛选了标题,摘要,以及针对接受癌症治疗的患者的合格文章的全文,雇用ECA,并报告临床结果。
    结果:在筛选的629篇文章中,这次审查中包括23人。最早的纳入研究发表于1996年,而大多数研究发表于过去5年。44%(10/23)的ECA用于血液相关癌症研究。地理上,30%(7/23)的研究是在美国进行的,22%(5/23)在日本,9%(2/23)在韩国。用于构建ECA的主要数据源涉及来自先前试验的汇总数据(35%,8/23),行政健康数据库(17%,4/23)和电子病历(17%,4/23)。虽然52%(12/23)的研究采用了调整治疗和ECA特征的方法,48%(11/23)缺乏明确的策略。
    结论:ECA为肿瘤学研究提供了一种有价值的方法,特别是当替代设计是不可行的。然而,仔细的方法规划和详细的报告对于有意义和可靠的结果至关重要。
    OBJECTIVE: Randomized controlled trials (RCTs) are the gold standard for evaluating the comparative efficacy and safety of new cancer therapies. However, enrolling patients in control arms of clinical trials can be challenging for rare cancers, particularly in the context of precision oncology and targeted therapies. External Control Arms (ECAs) are a potential solution to address these challenges in clinical research design. We conducted a scoping review to explore the use of ECAs in oncology.
    METHODS: We systematically searched four databases, namely MEDLINE, EMBASE, Web of Science, and Scopus. We screened titles, abstracts, and full texts for eligible articles focusing on patients undergoing therapy for cancer, employing ECAs, and reporting clinical outcomes.
    RESULTS: Of the 629 articles screened, 23 were included in this review. The earliest included studies were published in 1996, while most studies were published in the past 5 years. 44% (10/23) of ECAs were employed in blood-related cancer studies. Geographically, 30% (7/23) of studies were conducted in the United States, 22% (5/23) in Japan, and 9% (2/23) in South Korea. The primary data sources used to construct the ECAs involved pooled data from previous trials (35%, 8/23), administrative health databases (17%, 4/23) and electronic medical records (17%, 4/23). While 52% (12/23) of the studies employed methods to align treatment and ECAs characteristics, 48% (11/23) lacked explicit strategies.
    CONCLUSIONS: ECAs offer a valuable approach in oncology research, particularly when alternative designs are not feasible. However, careful methodological planning and detailed reporting are essential for meaningful and reliable results.

    背景:在美国,领先的医学协会建议每天服用81毫克阿司匹林,以预防处于危险中的女性先兆子痫(PE),而英国的NICE指南推荐剂量高达150mg的阿司匹林.最近的数据还表明,在肥胖人群中,剂量不足或阿司匹林抵抗可能会影响目前推荐剂量的阿司匹林疗效.
    目的:我们评估了在高危肥胖孕妇中,每日服用162mg阿司匹林是否比81mg阿司匹林更有效地降低具有严重特征的PE的发生率。
    方法:我们在2019年5月至2022年11月之间进行了一项随机试验。12至20周胎龄(GA)的个体,在招募时BMI≥30kg/m2,和三个高危因素中的至少一个:怀孕前的PE病史,至少在妊娠指数中记录了I期高血压,孕前糖尿病或在20周之前诊断为妊娠糖尿病,随机分为每日162mg或81mg阿司匹林,直至分娩。参与者对治疗分配没有盲化.排除标准为:多胎妊娠,已知的主要胎儿畸形,癫痫症,基线蛋白尿,由于其他适应症,服用阿司匹林,或阿司匹林的禁忌症。主要结局是具有严重特征的PE(PE或具有严重特征的叠加PE,子痫,或帮助)。次要结局包括PE导致的早产率,小于胎龄(SGA),产后出血,早剥,和药物副作用。使用对主要结果的预先计划的贝叶斯分析,需要220的样本量,以中性信息先验估计受益或损害的后验概率。
    结果:在343名符合条件的个人中,220例(64.1%)随机分组。主要结果为209/220(95%)。组间基线特征相似,纳入研究时,162mg阿司匹林组为15.9周,81mg阿司匹林组为15.6周.16周前的登记发生在55/110分配到162mg和58/110分配到81mg阿司匹林。162mg阿司匹林组的主要结局为35%,81mg阿司匹林组的主要结局为40%(后相对风险,0.88;95%可信区间,0.64-1.22)。贝叶斯分析表明,与81mg阿司匹林剂量相比,162mg阿司匹林降低主要结局的概率为78%。由于先兆子痫引起的指示早产率(21%vs21%),SGA(6.5%对2.9%),两组之间的早剥(2.8%vs3.0%)和产后出血(10%vs8.8%)相似。药物不良反应也相似。
    结论:在高危肥胖个体中,有78%的获益概率是162mg阿司匹林与81mg阿司匹林相比可降低具有严重特征的PE的发生率.在该人群中使用162mg阿司匹林与81mg阿司匹林相比,最佳估计减少了12%。此试验支持进行更大的多中心试验。
    BACKGROUND: In the United States, leading medical societies recommend 81 mg of aspirin daily for the prevention of preeclampsia (PE) in women at risk, whereas the NICE guidelines in the UK recommend a dose as high as 150 mg of aspirin. Recent data also suggest that in the obese population, inadequate dosing or aspirin resistance may impact the efficacy of aspirin at the currently recommend doses.
    OBJECTIVE: We evaluated whether daily administration of 162 mg aspirin would be more effective compared to 81 mg in decreasing the rate of PE with severe features in high-risk obese pregnant individuals.
    METHODS: We performed a randomized trial between May 2019 and November 2022. Individuals at 12 to 20-weeks gestational age (GA) with a BMI ≥ 30 kg/m2 at time to enrollment, and at least one of three high risk factors: history of PE in a prior pregnancy, at least stage I hypertension documented in the index pregnancy, pre-gestational diabetes or gestational diabetes diagnosed prior to 20 weeks GA were randomized to either 162 mg or 81 mg of aspirin daily till delivery, participants were not blinded to treatment allocation. Exclusion criteria were: multifetal gestation, known major fetal anomalies, seizure disorder, baseline proteinuria, on aspirin due to other indications, or contraindication to aspirin. The primary outcome was PE with severe features (PE or superimposed PE with severe features, eclampsia, or HELLP). Secondary outcomes included rates of preterm birth due to PE, small for gestational age (SGA), postpartum hemorrhage, abruption, and medication side effects. A sample size of 220 was needed using a preplanned Bayesian analysis of the primary outcome to estimate the posterior probability of benefit or harm with a neutral informative prior.
    RESULTS: Of 343 eligible individuals, 220 (64.1%) were randomized. The primary outcome was available for 209/220 (95%). Baseline characteristics were similar between groups, median gestational age at enrollment was 15.9 weeks in the 162 mg aspirin group and 15.6 weeks in the 81 mg aspirin group. Enrollment prior to 16 weeks occurred in 55/110 of those assigned to 162 mg and 58/110 of those assigned to 81 mg of aspirin. The primary outcome occurred in 35% in the 162 mg aspirin group and in 40% in the 81 mg aspirin group (posterior relative risk, 0.88; 95% credible interval, 0.64-1.22). Bayesian analysis indicated a 78% probability of a reduction in the primary outcome with 162 mg aspirin compared to 81 mg aspirin dose. Rates of indicated preterm birth due to preeclampsia (21% vs 21%), SGA (6.5% vs 2.9%), abruption (2.8% vs 3.0%) and postpartum hemorrhage (10% vs 8.8%) were similar between groups. Medication adverse effects were also similar.
    CONCLUSIONS: Among high-risk obese individuals, there was 78% probability of benefit that 162 mg aspirin compared to 81 mg will decrease the rate of PE with severe features. With a best estimate of a 12% reduction when using 162 mg of aspirin in comparison to 81 mg of aspirin in this population. This trial supports doing a larger multicenter trial.
