    本研究调查了急性IS患者血清ST2和钙卫蛋白的释放动力学。该研究包括NIH卒中量表评分≥8的急性IS患者(N=20)。在七个时间点进行采样:入院后(T0)和随后的24小时连续间隔(T1-T6)。使用改良的Rankin量表评估90天的主要结局:0-2表示良好,3-6表示不良功能结局。次要结果是90天后的全因死亡率。15名患者预后不佳,八个人死亡。结果显示,在T0时,良好和不良结果之间的ST2浓度存在统计学上的显着差异(p=0.04),T1(p=0.006),T2(p=0.01),T3(p=0.021),T4(p=0.007),T5(p=0.032),以及钙卫蛋白T6(p=0.034)。ST2在T1时的预后准确性最高,截止值>18.9µg/L(灵敏度为80%,特异性为100.0%),在T5时钙卫蛋白的截止值>4.5mg/L(灵敏度为64.3%,特异性为100.0%)。血清ST2和钙卫蛋白释放动力学显示了IS结果的有价值的预后准确性。
    This study investigated the releasing dynamics of serum ST2 and calprotectin in patients with acute IS. The study included acute IS patients (N = 20) with an NIH Stroke Scale score ≥8. Sampling was performed at seven time points: after admission (T0) and at the following 24 h consecutive intervals (T1-T6). Primary outcome at 90 days was evaluated using the modified Rankin scale: 0-2 for good and 3-6 for poor functional outcome. The secondary outcome was all-cause mortality after 90 days. Fifteen patients had a poor outcome, and eight died. Results showed a statistically significant difference in ST2 concentrations between good and poor outcomes at T0 (p = 0.04), T1 (p = 0.006), T2 (p = 0.01), T3 (p = 0.021), T4 (p = 0.007), T5 (p = 0.032), and for calprotectin T6 (p = 0.034). Prognostic accuracy was highest for ST2 at T1 for a cut-off > 18.9 µg/L (sensitivity 80% and specificity 100.0%) and for calprotectin at T5 for a cut-off > 4.5 mg/L (sensitivity 64.3% and specificity 100.0%). Serum ST2 and calprotectin-releasing dynamics showed a valuable prognostic accuracy for IS outcomes.

    这项研究确定了与非恶性脑实质相比,IDH野生型胶质母细胞瘤(GBM)组织中五种新型生物标志物候选物的表达,以及它们与GBM患者预后的相关性。通过免疫组织化学在肿瘤组织(n=186)和健康脑组织(n=54)中分析标志物。通过Kaplan-Meier和对数秩检验评估与患者总生存期(OS)和无进展生存期(PFS)的相关性。使用多变量Cox比例风险模型确定标志物的预后价值。AGTRAP,DIVERSIN,与健康大脑相比,细胞质NEDD8(NEDD8c)和RRM1在肿瘤组织中明显过表达,而ALKBH3则相反。AGTRAP,单因素分析中ALKBH3、NEDD8c和RRM1与OS显著相关。在多因素分析中,AGTRAP和RRM1也是OS的独立预后因素。对于PFS,只有AGTRAP和NEDD8c在单因素分析中达到显著性。此外,AGTRAP是多变量模型中PFS的独立预后因素。最后,标记物的联合分析提高了其预后的准确性.AGTRAP/ALKBH3组合对GBM患者的OS具有最强的预后价值。这些发现有助于更好地理解GBM病理生理学,并可能有助于确定此类癌症的新治疗靶标。
    This study determined the expression of five novel biomarker candidates in IDH wild-type glioblastoma (GBM) tissues compared to non-malign brain parenchyma, as well as their prognostic relevance for the GBM patients\' outcomes. The markers were analysed by immunohistochemistry in tumour tissues (n = 186) and healthy brain tissues (n = 54). The association with the patients\' overall survival (OS) and progression-free survival (PFS) was assessed by Kaplan-Meier and log-rank test. The prognostic value of the markers was determined using multivariate Cox proportional hazard models. AGTRAP, DIVERSIN, cytoplasmic NEDD8 (NEDD8c) and RRM1 were significantly overexpressed in tumour tissues compared to the healthy brain, while the opposite was observed for ALKBH3. AGTRAP, ALKBH3, NEDD8c and RRM1 were significantly associated with OS in univariate analysis. AGTRAP and RRM1 were also independent prognostic factors for OS in multivariate analysis. For PFS, only AGTRAP and NEDD8c reached significance in univariate analysis. Additionally, AGTRAP was an independent prognostic factor for PFS in multivariate models. Finally, combined analysis of the markers enhanced their prognostic accuracy. The combination AGTRAP/ALKBH3 had the strongest prognostic value for the OS of GBM patients. These findings contribute to a better understanding of the GBM pathophysiology and may help identify novel therapeutic targets in this type of cancer.

    我们比较了急诊(ED)合并脓毒性休克患者在脓毒症识别和复苏时的初始序贯器官衰竭评估(SOFAini)评分和最大SOFA评分(SOFAmax)在初始评分测量后24小时内的最差变量对院内死亡率的预测准确性。
    这是一项回顾性观察性研究,使用2015年10月至2019年12月在ED中对感染性休克患者进行多中心前瞻性登记。主要结果是院内死亡率。使用接受者工作特征(AUC)曲线下面积评估SOFAini和SOFAmax的预后准确性。
    共纳入4860名患者,住院死亡率为22.1%.在59.7%的患者中,与SOFAini相比,SOFAmax增加了,总SOFA评分的平均变化为2.0(标准差,2.3).根据总SOFA评分和SOFA分量评分,住院死亡率存在显着差异,心血管SOFA评分除外。SOFAmax的AUC(0.71;95%置信区间[CI],0.69-0.72)显著高于SOFAini(AUC,0.67;95%CI,0.66-0.69)用于预测住院死亡率。对于最大值,六个组分的所有得分的AUC较高。
    在感染性休克的ED患者中,识别脓毒症时的初始SOFA评分的预后准确性低于24小时最大SOFA评分。器官衰竭的后续评估可能会改善SOFA评分的差异,以预测死亡率。
    UNASSIGNED: We compared the prognostic accuracy of in-hospital mortality of the initial Sequential Organ Failure Assessment (SOFAini) score at the time of sepsis recognition and resuscitation and the maximum SOFA score (SOFAmax) using the worst variables in the 24 h after the initial score measurement in emergency department (ED) patients with septic shock.
    UNASSIGNED: This was a retrospective observational study using a multicenter prospective registry of septic shock patients in the ED between October 2015 and December 2019. The primary outcome was in-hospital mortality. The prognostic accuracies of SOFAini and SOFAmax were evaluated using the area under the receiver operating characteristic (AUC) curve.
    UNASSIGNED: A total of 4860 patients was included, and the in-hospital mortality was 22.1%. In 59.7% of patients, SOFAmax increased compared with SOFAini, and the mean change of total SOFA score was 2.0 (standard deviation, 2.3). There was a significant difference in in-hospital mortality according to total SOFA score and the SOFA component scores, except cardiovascular SOFA score. The AUC of SOFAmax (0.71; 95% confidence interval [CI], 0.69-0.72) was significantly higher than that of SOFAini (AUC, 0.67; 95% CI, 0.66-0.69) in predicting in-hospital mortality. The AUCs of all scores of the six components were higher for the maximum values.
    UNASSIGNED: The prognostic accuracy of the initial SOFA score at the time of sepsis recognition was lower than the 24-h maximal SOFA score in ED patients with septic shock. Follow-up assessments of organ failure may improve discrimination of the SOFA score for predicting mortality.

    背景:循环肿瘤DNA(ctDNA)的存在是治疗性实体瘤的预后。研究已经在特定的“地标”或多个“监测”时间点评估了ctDNA。然而,可变的结果导致其临床有效性的不确定性。
    方法:PubMed搜索确定了相关研究,评估在根治性治疗后实体瘤的ctDNA监测。使用Peto方法计算每个研究的地标和监测时间点的复发几率(OR),并在荟萃分析中汇总。估计通过个体研究逆方差加权的集合敏感性和特异性,并利用逆方差加权的线性回归进行meta回归,以探索患者和肿瘤特征与疾病复发的OR之间的关联。
    结果:在确定的39项研究中,30项(1924例)和24项研究(1516例)分别报道了界标和监测时间点。地标复发的合并OR为15.47(95%CI11.84-20.22),监测时为31.0(95%CI23.9-40.2)。地标和监测分析对ctDNA的合并敏感性为58.3%和82.2%。相应的特异性为92%和94.1%。肿瘤不可知组的预后准确性较低,而界标分析的时间较长,预后准确性较高。监测抽奖次数和吸烟史。辅助化疗对标志特异性产生负面影响。
    结论:尽管ctDNA的预后准确性很高,灵敏度低,边界高特异性,因此,适度的辨别准确性,特别是对于具有里程碑意义的分析。需要具有适当的测试策略和测定参数的适当设计的临床试验来证明临床实用性。
    Presence of circulating tumor DNA (ctDNA) is prognostic in solid tumors treated with curative intent. Studies have evaluated ctDNA at specific \"landmark\" or multiple \"surveillance\" time points. However, variable results have led to uncertainty about its clinical validity.
    A PubMed search identified relevant studies evaluating ctDNA monitoring in solid tumors after curative intent therapy. Odds ratios for recurrence at both landmark and surveillance time points for each study were calculated and pooled in a meta-analysis using the Peto method. Pooled sensitivity and specificity weighted by individual study inverse variance were estimated and meta-regression using linear regression weighted by inverse variance was performed to explore associations between patient and tumor characteristics and the odds ratio for disease recurrence.
    Of 39 studies identified, 30 (1924 patients) and 24 studies (1516 patients) reported on landmark and surveillance time points, respectively. The pooled odds ratio for recurrence at landmark was 15.47 (95% confidence interval = 11.84 to 20.22) and at surveillance was 31.0 (95% confidence interval = 23.9 to 40.2). The pooled sensitivity for ctDNA at landmark and surveillance analyses was 58.3% and 82.2%, respectively. The corresponding specificities were 92% and 94.1%, respectively. Prognostic accuracy was lower with tumor agnostic panels and higher with longer time to landmark analysis, number of surveillance draws, and smoking history. Adjuvant chemotherapy negatively affected landmark specificity.
    Although prognostic accuracy of ctDNA is high, it has low sensitivity, borderline high specificity, and therefore modest discriminatory accuracy, especially for landmark analyses. Adequately designed clinical trials with appropriate testing strategies and assay parameters are required to demonstrate clinical utility.

  • 文章类型: Observational Study
    目的:确定新型血清生物标志物在院外心脏骤停(OHCA)患者中的临床可行性目标温度管理(TTM)。
    方法:本研究是一项对接受TTM的OHCA患者进行的前瞻性观察性研究。我们测量了传统的生物标志物,神经元特异性烯醇化酶和S100钙结合蛋白(S-100B),以及新的生物标志物,包括tau蛋白,神经丝轻链(NFL),胶质纤维酸性蛋白(GFAP),和泛素C末端水解酶-L1(UCH-L1),在通过SIMOA免疫测定鉴定的自发循环恢复后0、24、48和72小时。主要结果是OHCA后6个月的神经学结果较差。
    结果:从2018年8月至2020年5月,本研究共纳入100例患者。在纳入的患者中,46例患者在OHCA后6个月有良好的神经系统预后。所有常规和新的血清生物标志物都能够区分好的和差的神经学结果组(p<0.001)。新的血清生物标志物的曲线下面积在心脏骤停(CA)后72小时最高(Tau为0.906,NFL为0.946,GFAP为0.875,UCH-L1为0.935)。CA后72小时的NFL敏感度最高(77.1%,95%CI59.9-89.6)在维持100%特异性的同时预测不良神经系统预后。
    结论:新的血清生物标志物可靠地预测了接受TTM治疗的OHCA患者在未停止维持生命治疗时的不良神经系统预后。在我们的研究中,对两项大型现有研究(TTM和COMACARE子研究)的截止值进行了外部验证。新生物标志物的预测能力在CA后72小时最高。
    To determine the clinical feasibility of novel serum biomarkers in out-of-hospital cardiac arrest (OHCA) patients treated with target temperature management (TTM).
    This study was a prospective observational study conducted on OHCA patients who underwent TTM. We measured conventional biomarkers, neuron‑specific enolase and S100 calcium-binding protein (S-100B), as well as novel biomarkers, including tau protein, neurofilament light chain (NFL), glial fibrillary acidic protein (GFAP), and ubiquitin C-terminal hydrolase-L1 (UCH-L1), at 0, 24, 48, and 72 h after the return of spontaneous circulation identified by SIMOA immunoassay. The primary outcome was poor neurological outcome at 6 months after OHCA.
    A total of 100 patients were included in this study from August 2018 to May 2020. Among the included patients, 46 patients had good neurologic outcomes at 6 months after OHCA. All conventional and novel serum biomarkers had the ability to discriminate between the good and poor neurological outcome groups (p < 0.001). The area under the curves of the novel serum biomarkers were highest at 72 h after cardiac arrest (CA) (0.906 for Tau, 0.946 for NFL, 0.875 for GFAP, and 0.935 for UCH-L1). The NFL at 72 h after CA had the highest sensitivity (77.1%, 95% CI 59.9-89.6) in predicting poor neurological outcomes while maintaining 100% specificity.
    Novel serum biomarkers reliably predicted poor neurological outcomes for patients with OHCA treated with TTM when life-sustaining therapy was not withdrawn. Cutoffs from two large existing studies (TTM and COMACARE substudy) were externally validated in our study. The predictive power of the novel biomarkers was the highest at 72 h after CA.

    大多数无源发热(FWS)的儿童需要进行诊断性实验室检查以排除严重的细菌感染(SBI)。通常是入院和经验性抗生素。由于患有病毒感染的发热儿童不太可能患有SBI,确定全身病毒感染患者可能有助于排除SBI.我们评估了血液中病毒的存在是否可以用作生物标志物以排除SBI。前瞻性招募<3岁的FWS儿童,并对血液中的腺病毒进行实时(逆转录)PCR,肠病毒,副病毒,HHV620/135名患者患有SBI,在47/135中,血液中至少检测到一种病毒。与CRP(65%和93%)和PCT(55%和90%)相比,病毒血症具有更高的敏感性和阴性预测值(90%和96%)以排除SBI。在非病毒血症患者中存在SBI的比值比(OR)为5.8(p=0.0225),CRP≥40mg/l(p=0.0009)为5.5,PCT≥0.5ng/mL(0.0093)为3.7。在调整CRP和PCT后,这仍然是显著的(OR分别为5.6和5.9;两者的p=0.03)。CRP和PCT的ROC曲线下面积分别为0.754和0.779。但分别增加到0.803和0.832,当合并病毒血症时。
    结论:在排除SBI方面,病毒血症的存在比常用的生物标志物具有更好的表现,并且可能与CRP和/或PCT联合用于FWS患儿的评估。较大的研究应评估通过血浆中(逆转录)PCR对病毒进行即时检测在FWS儿童管理算法中的作用。
    背景:•大多数FWS儿童患有病毒感染,但高达15%的人有SBI;大多数需要实验室测试,以及许多入院和经验性抗生素。•患有病毒感染的儿童不太可能患有SBI。
    背景:•患有全身性病毒感染的儿童不太可能患有SBI。•病毒血症比常用的生物标志物更好地预测SBI缺乏,并且可能与CRP和/或PCT一起用于评估FWS儿童。
    Most children with fever without source (FWS) require diagnostic laboratory tests to exclude a serious bacterial infection (SBI), often followed by admission and empirical antibiotics. As febrile children with a viral infection are less likely to have a SBI, identifying patients with systemic viral infection could contribute to exclude SBI. We evaluated whether the presence of virus in the blood could be used as a biomarker to rule out SBI. Children < 3 years old with FWS were prospectively enrolled and had real-time (reverse-transcription) PCR performed on the blood for adenovirus, enterovirus, parechovirus, and HHV6. 20/135 patients had SBI, and in 47/135, at least one virus was detected in the blood. Viremia had a higher sensitivity and negative predictive value (90% and 96%) to rule out SBI compared to CRP (65% and 93%) and PCT (55% and 90%). The odds ratio (OR) for the presence of SBI among non-viremic patients was 5.8 (p = 0.0225), compared to 5.5 for CRP ≥ 40 mg/l (p = 0.0009) and 3.7 for PCT ≥ 0.5 ng/mL (0.0093). This remained significant after adjusting for CRP and PCT (OR 5.6 and 5.9, respectively; p = 0.03 for both). Area under the ROC curve for CRP and PCT were 0.754 and 0.779, respectively, but increased to 0.803 and 0.832, respectively, when combined with viremia.
    CONCLUSIONS: The presence of viremia had a better performance than commonly used biomarkers to rule-out SBI and could potentially be used in conjunction with CRP and/or PCT in the evaluation of children with FWS. Larger studies should evaluate the role of point-of-care testing of viruses by (revere-transcription) PCR in the plasma in management algorithms of children with FWS.
    BACKGROUND: • Most children with FWS have a viral infection, but up to 15% have a SBI; most require laboratory tests, and many admission and empirical antibiotics. • Children with a viral infection are less likely to have a SBI.
    BACKGROUND: • Children with a systemic viral infection are less likely to have an SBI. • Viremia is a better predictor of absence of SBI than commonly used biomarkers and could potentially be used in conjunction with CRP and/or PCT in the evaluation of children with FWS.

    背景:多形性胶质母细胞瘤(GBM)是最常见和侵袭性的原发性脑肿瘤。先前对GBM生物标志物的研究集中于生物标志物对总生存期(OS)的影响。直到现在,尚未发表评估预测OS的生物标志物性能的研究。我们检查了microRNA的性能,基因表达,基因签名,和甲基化,以前被确定为预后。此外,我们调查了将临床危险因素与生物标志物结合使用是否可以改善预后表现.
    方法:癌症基因组图谱,提供生物标志物和操作系统信息,在这项研究中使用。时间依赖性受试者工作特征(ROC)曲线用于评估预后准确性。
    结果:关于OS在诊断后2年的预后,微小RNA的ROC曲线下面积(AUC),Mir21和Mir222分别为0.550和0.625。当年龄包括在这些生物标志物的风险预测评分中时,AUC分别增加至0.719和0.701。SAMSN1基因表达的AUC为0.563,而Bao鉴定的“8基因”标记的AUC为0.613。
    结论:尽管一些生物标志物与OS显著相关,这些生物标志物预测OS事件的能力有限.纳入临床危险因素,比如年龄,可以大大提高预后表现。
    BACKGROUND: Glioblastoma multiforme (GBM) is the most common and aggressive primary brain tumor. Previous studies on GBM biomarkers focused on the effect of the biomarkers on overall survival (OS). Until now, no study has been published that evaluates the performance of biomarkers for prognosing OS. We examined the performance of microRNAs, gene expressions, gene signatures, and methylation that were previously identified to be prognostic. In addition, we investigated whether using clinical risk factors in combination with biomarkers can improve the prognostic performance.
    METHODS: The Cancer Genome Atlas, which provides both biomarkers and OS information, was used in this study. The time-dependent receiver operating characteristic (ROC) curve was used to evaluate the prognostic accuracy.
    RESULTS: For prognosis of OS by 2 years from diagnosis, the area under the ROC curve (AUC) of microRNAs, Mir21 and Mir222, was 0.550 and 0.625, respectively. When age was included in the risk prediction score of these biomarkers, the AUC increased to 0.719 and 0.701, respectively. The SAMSN1 gene expression attains an AUC of 0.563, and the \"8-gene\" signature identified by Bao achieves an AUC of 0.613.
    CONCLUSIONS: Although some biomarkers are significantly associated with OS, the ability of these biomarkers for prognosing OS events is limited. Incorporating clinical risk factors, such as age, can greatly improve the prognostic performance.

    生存预测在临终关怀临床实践中受到高度重视,患者表现状况评估是生存预后的主要组成部分。虽然当前的绩效状态评估工具仅限于其主观性质,可穿戴技术的出现可以持续记录患者的活动,并有可能客观地衡量表现状况。我们假设腕带肌动监测设备可以预测终末期癌症患者入院期间的住院死亡。本研究的目的是训练和验证基于可穿戴式活动记录设备活动数据的长短期记忆(LSTM)深度学习预测模型。这项研究招募了60名终末期癌症患者在临终关怀病房,28人死亡,32人在住院结束时病情稳定。标准Karnofsky性能状态评分的总体预后准确性为0.83。基于患者连续肌动监测的LSTM预测模型的总体预后准确率为0.83。此外,随着输入数据长度延长到48小时,模型性能得到了提高。我们的研究表明,在终末期癌症患者的姑息治疗中,腕带式肌动仪预测临终入院结局的潜在可行性.临床试验注册:研究方案在ClinicalTrials.gov(ID:NCT04883879)上注册。
    Survival prediction is highly valued in end-of-life care clinical practice, and patient performance status evaluation stands as a predominant component in survival prognostication. While current performance status evaluation tools are limited to their subjective nature, the advent of wearable technology enables continual recordings of patients\' activity and has the potential to measure performance status objectively. We hypothesize that wristband actigraphy monitoring devices can predict in-hospital death of end-stage cancer patients during the time of their hospital admissions. The objective of this study was to train and validate a long short-term memory (LSTM) deep-learning prediction model based on activity data of wearable actigraphy devices. The study recruited 60 end-stage cancer patients in a hospice care unit, with 28 deaths and 32 discharged in stable condition at the end of their hospital stay. The standard Karnofsky Performance Status score had an overall prognostic accuracy of 0.83. The LSTM prediction model based on patients\' continual actigraphy monitoring had an overall prognostic accuracy of 0.83. Furthermore, the model performance improved with longer input data length up to 48 h. In conclusion, our research suggests the potential feasibility of wristband actigraphy to predict end-of-life admission outcomes in palliative care for end-stage cancer patients. Clinical Trial Registration: The study protocol was registered on ClinicalTrials.gov (ID: NCT04883879).

    本研究旨在确定SOFA与快速SOFA(qSOFA)和全身炎症反应综合征(SIRS)在预测急诊科(ED)感染患者28天死亡率方面的预后准确性。
    对2017年10月至2018年3月在丹麦接受ED的有记录或疑似感染的成年患者的前瞻性研究数据的二次分析。在调整慢性病后计算SOFA评分。通过敏感性分析评估预后的准确性,特异性,预测值,似然比,和受试者工作特征曲线下面积(AUROC),95%置信区间(CI)。
    共纳入2045例患者,中位年龄为73.2岁(IQR:60.9-82.1岁)。28天总死亡率为7.7%。在符合SOFA评分≥2、qSOFA评分≥2和SIRS标准≥2的患者中,28天死亡率为13.6%(11.2-16.3),17.8%(12.4-24.3)和8.3%(6.7-10.2),分别。SOFA≥2的敏感性为61.4%(53.3-69.0),特异性为67.3%(65.1-69.4),qSOFA≥2的敏感性为19.6%(13.7-26.7),特异性为92.4%(91.1-93.6),SIRS≥2的敏感性为52.5%(44.4-60.5),特异性为51.5%(49.2-53.7)。与SIRS相比,SOFA的AUROC为:0.68vs0.52;p<0.001,与qSOFA相比:0.68vs0.63;p=0.018。
    与SIRS和qSOFA相比,至少2分的SOFA对28天死亡率具有更好的预后准确性。然而,SOFA预测28日死亡率的总体准确性较差.
    UNASSIGNED: This study aimed to determine the prognostic accuracy of SOFA in comparison to quick-SOFA (qSOFA) and systemic inflammatory response syndrome (SIRS) in predicting 28-day mortality in the emergency department (ED) patients with infections.
    UNASSIGNED: A secondary analysis of data from a prospective study of adult patients with documented or suspected infections admitted to an ED in Denmark from Oct-2017 to Mar-2018. The SOFA scores were calculated after adjustment for chronic diseases. The prognostic accuracy was assessed by analysis of sensitivity, specificity, predictive values, likelihood ratios, and area under the receiver operating characteristic curve (AUROC) with 95% confidence intervals (CI).
    UNASSIGNED: A total of 2045 patients with a median age of 73.2 (IQR: 60.9-82.1) years were included. The overall 28-day mortality was 7.7%. In patients meeting a SOFA score ≥2, qSOFA score ≥2, and SIRS criteria ≥2 the 28-day mortality was 13.6% (11.2-16.3), 17.8% (12.4-24.3) and 8.3% (6.7-10.2), respectively. SOFA ≥2 had a sensitivity of 61.4% (53.3-69.0) and specificity of 67.3% (65.1-69.4), qSOFA ≥2 had a sensitivity of 19.6% (13.7-26.7) and specificity of 92.4% (91.1-93.6), and SIRS ≥2 had a sensitivity of 52.5% (44.4-60.5) and specificity of 51.5% (49.2-53.7). The AUROC for SOFA compared to SIRS was: 0.68 vs 0.52; p<0.001 and compared to qSOFA: 0.68 vs 0.63; p=0.018.
    UNASSIGNED: A SOFA score of at least two had better prognostic accuracy for 28-day mortality than SIRS and qSOFA. However, the overall accuracy of SOFA was poor for the prediction of 28-day mortality.

    从开始到2019年6月,对电子数据库进行了系统评价,以评估IBDX®的预后准确性和临床影响(克罗恩病预后测试;GlycomindsLtd,Lod,以色列)生物标志物分层工具和PredictSURE-IBD™(PredictImmuneLtd,剑桥,英国)工具。报告克罗恩病治疗成本效益的研究的系统评价从开始到2019年7月。两名审稿人独立同意纳入研究,评估纳入研究的质量,并验证从研究中提取的数据。研究中的临床和方法学异质性排除了预后准确性数据的综合。开发了一种从头经济模型,以比较两种治疗方法的成本和后果-“自上而下”和“逐步”策略,在接受克罗恩病严重病程的高风险人群中,加强标准护理。该模型包括决策树和马尔可夫队列模型。
    16种出版物,包括8项原始研究(n=1478),被认为与预后准确性的审查有关。还审查了营销预后工具的公司提供的文件。无符合IBDX生物标志物分层工具敏感性或特异性合格标准的研究报告,而一项研究提供了敏感性的估计,PredictSURE-IBD工具的特异性和阴性预测值。所有确定的研究都是观察性的,被认为对工具的有效性提供了微弱的证据。由于这两种工具的数据很少,在基本病例分析中,假设PredictSURE-IBD的准确度为100%.在情景分析中,IBDX的准确性假设为100%,测试的成本是分析之间的唯一区别。对成本效益的增量分析表明,自上而下(通过在模型中使用PredictSURE-IBD)比提高(通过模型的标准护理部门)成本更高,并且产生的质量调整生命年数更少。
    尽管对文献进行了广泛的系统搜索,对于生物标志物分层工具IBDX和PredictSURE-IBD的预后准确性,未发现确凿的证据.
    尽管模型表明标准护理在测试中占主导地位,缺乏两种检测预后准确性的证据,以及自上而下和阶梯式治疗方法获益的不确定性,意味着这些结果应被解释为指示性的,而不是确定性的.

    克罗恩病是消化系统的一部分发炎(肿胀)的病症。任何年龄的人都可能患上克罗恩病。这是一种终生无法治愈的疾病。在英国,克罗恩病影响约1每650人。消化系统的任何部分都可能受到影响,疾病的严重程度因人而异。症状来来去去,有时根本没有症状。克罗恩病的常见症状是腹泻,胃痛和粪便中的血。给予治疗以减轻或控制症状,并试图阻止炎症复发。一些患有克罗恩病的人比其他人更有可能有更多的复发,并发展可能需要手术的克罗恩病并发症。该项目研究了两种工具在识别可能出现并发症或需要手术的克罗恩病患者方面的效果。识别那些有更高的机会经历克罗恩病并发症的人可以帮助他们和他们的医生选择他们的治疗方法,目的是减少复发次数和长期手术风险。此外,审查评估了这些工具是否物有所值。我们发现有限的证据表明,这些工具在识别更有可能发生克罗恩病并发症的人方面有多好。缺乏有关工具的证据意味着成本效益分析只能评估此时在临床实践中给予的治疗或更有可能发生并发症的人的更强化治疗的资金价值。分析发现,对于发生克罗恩病并发症的机会较高的人,当前的标准护理比强化治疗提供了更多的金钱价值。
    Crohn\'s disease is a lifelong condition that can affect any segment of the gastrointestinal tract. Some people with Crohn\'s disease may be at higher risk of following a severe course of disease than others and being able to identify the level of risk a patient has could lead to personalised management.
    To assess the prognostic test accuracy, clinical impact and cost-effectiveness of two tools for the stratification of people with a diagnosis of Crohn\'s disease by risk of following a severe course of disease.
    The data sources MEDLINE, EMBASE, the Cochrane Database of Systematic Reviews and the Cochrane Central Register of Controlled Trials were searched to inform the systematic reviews on prognostic accuracy, clinical impact of the prognostic tools, and economic evaluations. Additional data sources to inform the review of economic evaluations were NHS Economic Evaluation Database, Database of Abstracts of Reviews of Effects and the Health Technology Assessment Database.
    Systematic reviews of electronic databases were carried out from inception to June 2019 for studies assessing the prognostic accuracy and clinical impact of the IBDX® (Crohn\'s disease Prognosis Test; Glycominds Ltd, Lod, Israel) biomarker stratification tool and the PredictSURE-IBD™ (PredictImmune Ltd, Cambridge, UK) tool. Systematic reviews of studies reporting on the cost-effectiveness of treatments for Crohn\'s disease were run from inception to July 2019. Two reviewers independently agreed on studies for inclusion, assessed the quality of included studies and validated the data extracted from studies. Clinical and methodological heterogeneity across studies precluded the synthesis of data for prognostic accuracy. A de novo economic model was developed to compare the costs and consequences of two treatment approaches - the \'top-down\' and \'step-up\' strategies, with step-up considered standard care - in people at high risk of following a severe course of Crohn\'s disease. The model comprised a decision tree and a Markov cohort model.
    Sixteen publications, including eight original studies (n = 1478), were deemed relevant to the review of prognostic accuracy. Documents supplied by the companies marketing the prognostic tools were also reviewed. No study meeting the eligibility criteria reported on the sensitivity or specificity of the IBDX biomarker stratification tool, whereas one study provided estimates of sensitivity, specificity and negative predictive value for the PredictSURE-IBD tool. All identified studies were observational and were considered to provide weak evidence on the effectiveness of the tools. Owing to the paucity of data on the two tools, in the base-case analysis the accuracy of PredictSURE-IBD was assumed to be 100%. Accuracy of IBDX was assumed to be 100% in a scenario analysis, with the cost of the tests being the only difference between the analyses. The incremental analysis of cost-effectiveness demonstrated that top-down (via the use of PredictSURE-IBD in the model) is more expensive and generates fewer quality-adjusted life-years than step-up (via the standard care arm of the model).
    Despite extensive systematic searches of the literature, no robust evidence was identified of the prognostic accuracy of the biomarker stratification tools IBDX and PredictSURE-IBD.
    Although the model indicates that standard care dominates the tests, the lack of evidence of prognostic accuracy of the two tests and the uncertainty around the benefits of the top-down and step-up treatment approaches mean that the results should be interpreted as indicative rather than definitive.

    Crohn’s disease is a condition in which parts of the digestive system become inflamed (swollen). People of any age can develop Crohn’s disease. It is a lifelong condition for which there is no cure. In the UK, Crohn’s disease affects about 1 in every 650 people. Any part of the digestive system can be affected, and the severity of the disease can vary from person to person. Symptoms come and go, and there can be times when there are no symptoms at all. Common symptoms of Crohn’s disease are diarrhoea, stomach-ache and blood in faeces. Treatment is given to reduce or control symptoms and to try to stop inflammation from coming back. Some people with Crohn’s disease are more likely than others to have more relapses and to develop complications of Crohn’s disease that might require surgery. This project looked at how well two tools worked at identifying people with Crohn’s disease who might develop complications or need surgery. Identifying those who have a higher chance of experiencing complications of Crohn’s disease could help them and their doctor to choose their treatment, with the goal of reducing the number of relapses and the risk of surgery in the longer term. In addition, the review assessed whether or not the tools offered value for money. We found limited evidence of how well the tools worked in identifying people who were more likely to develop complications of Crohn’s disease. The lack of evidence on the tools meant that the cost-effectiveness analysis could only assess the value for money of the treatment that is given in clinical practice at this time or of more intensive treatments for people who are more likely to develop complications. The analysis found that current standard care offers more value for money than intensive treatments for people with a higher chance of developing complications of Crohn’s disease.
