    目的:治疗肺癌时,有必要识别早期治疗失败,以便及时进行治疗调整。这项研究的目的是研究化疗和贝伐单抗治疗期间肿瘤扩散的变化是否可以作为治疗失败的预测因子。
    方法:前瞻性单臂,开放标签,临床试验于2014年9月至2020年12月进行,纳入IV期非小细胞肺癌(NSCLC)患者.患者接受化疗-抗血管生成联合治疗。基线时进行弥散加权磁共振成像(DW-MRI),两个,四,开始治疗后16周。将治疗前和治疗后MRI之间的表观扩散系数(ADC)值的差异记录为Delta值(ΔADC)。我们评估了ΔADC是否可以作为总生存期(OS)的预后生物标志物,有五年的随访。
    结果:18例患者纳入最终分析。ΔADC值≥-3的患者表现出明显更长的OS,HR为0.12(95%CI;0.03-0.61;p=0.003)ΔADC值≥-3的患者的中位OS为18个月,(95%C.I;7-46)与ΔADC值<-3的那些中的7个月(95%C.I;5-9)相比。
    结论:我们的研究结果表明,肿瘤ADC值的早期变化,可能表示OS更长。因此,DW-MRI可以作为早期生物标志物,用于评估接受化疗联合抗血管生成治疗的患者的治疗反应。
    OBJECTIVE: When treating Lung Cancer, it is necessary to identify early treatment failure to enable timely therapeutic adjustments. The Aim of this study was to investigate whether changes in tumor diffusion during treatment with chemotherapy and bevacizumab could serve as a predictor of treatment failure.
    METHODS: A prospective single-arm, open-label, clinical trial was conducted between September 2014 and December 2020, enrolling patients with stage IV non-small cell lung cancer (NSCLC). The patients were treated with chemotherapy-antiangiogenic combination. Diffusion weighted magnetic resonance imaging (DW-MRI) was performed at baseline, two, four, and sixteen weeks after initiating treatment. The differences in apparent diffusion coefficient (ADC) values between pre- and post-treatment MRIs were recorded as Delta values (ΔADC). We assessed whether ΔADC could serve as a prognostic biomarker for overall survival (OS), with a five year follow up.
    RESULTS: 18 patients were included in the final analysis. Patients with a ΔADC value ≥ -3 demonstrated a significantly longer OS with an HR of 0.12 (95 % CI; 0.03- 0.61; p = 0.003) The median OS in patients with a ΔADC value ≥ -3 was 18 months, (95 % C.I; 7-46) compared to 7 months (95 % C.I; 5-9) in those with a ΔADC value < -3.
    CONCLUSIONS: Our findings suggest that early changes in tumor ADC values, may be indicative of a longer OS. Therefore, DW-MRI could serve as an early biomarker for assessing treatment response in patients receiving chemotherapy combined with antiangiogenic therapy.

    背景:危重患者外周血中存在有核红细胞(NRBC)与不良预后相关。关于SARS-CoV-2诱发的急性呼吸窘迫综合征(ARDS)患者中NRBC的预测价值的证据仍然难以捉摸。这项研究的目的是评估NRBC在这些患者中的预测有效性。
    方法:评估SARS-CoV-2诱导的ARDS成年患者的每日NRBC值,并对其死亡率的预测效度进行统计学评估。根据ICU住院期间患者的最大NRBC值计算并根据Youden的方法进一步指定截止水平。根据这个截止值,我们进行了进一步分析,如logistic回归模型和生存率.
    结果:分析413例SARS-CoV-2致ARDS的危重患者。与存活的患者相比,未存活的患者在ICU住院期间的NRBC值明显更高(1090/μl[310;3883]vs.140/μl[20;500];p<0.0001)。重度ARDS患者(n=374)在ICU住院期间的NRBC值明显高于中度ARDS患者(n=38)(490/μl[120;1890]vs.30/μl[10;476];p<0.0001)。发现NRBC的截止水平≥500/μl可以最好地分层风险,并且与ICU住院时间更长有关(12[8;18]vs.18[13;27]天;p<0.0001)和更长的机械通气持续时间(10[6;16]vs.17[12;26]天;p<0.0001)。多变量校正的Logistic回归分析显示,NRBC≥500/µl是死亡率的独立危险因素(比值比(OR)4.72;95%置信区间(CI)2.95-7.62,p<0.0001)。NRBC值低于阈值500/μl的患者比高于阈值的患者具有显着的生存优势(中位生存32[95%CI8.7-43.3]与21天[95%CI18.2-23.8],对数秩检验,p<0.05)。在ICU入住期间达到NRBC阈值≥500/μl的患者的长期死亡率显着增加(中位生存期489天,对数秩检验,p=0.0029,风险比(HR)3.2,95%CI1.2-8.5)。
    结论:NRBCs预测SARS-CoV-2诱导的ARDS危重患者的死亡率,具有较高的预后能力。需要进一步的研究来确认NRBC的临床影响,以最终提高决策。
    BACKGROUND: The presence of nucleated red blood cells (NRBCs) in the peripheral blood of critically ill patients is associated with poor outcome. Evidence regarding the predictive value of NRBCs in patients with SARS-CoV-2-induced acute respiratory distress syndrome (ARDS) remains elusive. The aim of this study was to evaluate the predictive validity of NRBCs in these patients.
    METHODS: Daily NRBC values of adult patients with SARS-CoV-2-induced ARDS were assessed and their predictive validity for mortality was statistically evaluated. A cut-off level based on the patient\'s maximum NRBC value during ICU stay was calculated and further specified according to Youden\'s method. Based on this cut-off value, further analyses such as logistic regression models and survival were performed.
    RESULTS: 413 critically ill patients with SARS-CoV-2-induced ARDS were analyzed. Patients who did not survive had significantly higher NRBC values during their ICU stay compared to patients who survived (1090/µl [310; 3883] vs. 140/µl [20; 500]; p < 0.0001). Patients with severe ARDS (n = 374) had significantly higher NRBC values during ICU stay compared to patients with moderate ARDS (n = 38) (490/µl [120; 1890] vs. 30/µl [10; 476]; p < 0.0001). A cut-off level of NRBC ≥ 500/µl was found to best stratify risk and was associated with a longer duration of ICU stay (12 [8; 18] vs. 18 [13; 27] days; p < 0.0001) and longer duration of mechanical ventilation (10 [6; 16] vs. 17 [12; 26] days; p < 0.0001). Logistic regression analysis with multivariate adjustment showed NRBCs ≥ 500/µl to be an independent risk factor of mortality (odds ratio (OR) 4.72; 95% confidence interval (CI) 2.95-7.62, p < 0.0001). Patients with NRBC values below the threshold of 500/µl had a significant survival advantage over those above the threshold (median survival 32 [95% CI 8.7-43.3] vs. 21 days [95% CI 18.2-23.8], log-rank test, p < 0.05). Patients who once reached the NRBC threshold of ≥ 500/µl during their ICU stay had a significantly increased long-term mortality (median survival 489 days, log-rank test, p = 0.0029, hazard ratio (HR) 3.2, 95% CI 1.2-8.5).
    CONCLUSIONS: NRBCs predict mortality in critically ill patients with SARS-CoV-2-induced ARDS with high prognostic power. Further studies are required to confirm the clinical impact of NRBCs to eventually enhance decision making.

    背景:本研究旨在评估总肿瘤体积(TTV)对结直肠癌肝转移(CRLM)患者早期复发(6个月内)和总生存期(OS)的预后价值,采用诱导全身治疗,然后进行完全局部治疗。
    方法:纳入了多中心随机3期CAIRO5试验(NCT02162563)中最初不可切除的CRLM患者,这些患者接受了诱导全身治疗,然后进行了局部治疗。使用全身治疗前后的CT扫描计算基线TTV和对全身治疗反应的TTV变化。并评估其增加的预后价值。这些发现在三级中心接受治疗的患者的外部队列中得到了验证。
    结果:总计,包括215例CAIRO5患者。在多变量分析中,基线TTV和TTV的绝对变化与早期复发(分别为P=0.005和P=0.040)和OS显着相关(分别为P=0.024和P=0.006),而RECIST1.1对早期复发(P=0.88)和OS(P=0.35)无预后。在验证队列中(n=85),在多变量分析中,基线TTV和TTV的绝对变化仍然是早期复发的预后(分别为P=0.041和P=0.021)和OS(分别为P<0.0001和P=0.012),并显示出比常规临床病理变量增加的预后价值(增加C统计量,0.06;95%CI,0.02至0.14;P=0.008)。
    结论:在接受最初不可切除的CRLM的完全局部治疗的患者中,总肿瘤体积对早期复发和OS具有强烈的预后。在CAIRO5试验和验证队列中。相比之下,RECIST1.1对早期复发和OS均未显示预后价值。
    BACKGROUND: This study aimed to assess the prognostic value of total tumor volume (TTV) for early recurrence (within 6 months) and overall survival (OS) in patients with colorectal liver metastases (CRLM), treated with induction systemic therapy followed by complete local treatment.
    METHODS: Patients with initially unresectable CRLM from the multicenter randomized phase 3 CAIRO5 trial (NCT02162563) who received induction systemic therapy followed by local treatment were included. Baseline TTV and change in TTV as response to systemic therapy were calculated using the CT scan before and the first after systemic treatment, and were assessed for their added prognostic value. The findings were validated in an external cohort of patients treated at a tertiary center.
    RESULTS: In total, 215 CAIRO5 patients were included. Baseline TTV and absolute change in TTV were significantly associated with early recurrence (P = 0.005 and P = 0.040, respectively) and OS in multivariable analyses (P = 0.024 and P = 0.006, respectively), whereas RECIST1.1 was not prognostic for early recurrence (P = 0.88) and OS (P = 0.35). In the validation cohort (n = 85), baseline TTV and absolute change in TTV remained prognostic for early recurrence (P = 0.041 and P = 0.021, respectively) and OS in multivariable analyses (P < 0.0001 and P = 0.012, respectively), and showed added prognostic value over conventional clinicopathological variables (increase C-statistic, 0.06; 95 % CI, 0.02 to 0.14; P = 0.008).
    CONCLUSIONS: Total tumor volume is strongly prognostic for early recurrence and OS in patients who underwent complete local treatment of initially unresectable CRLM, both in the CAIRO5 trial and the validation cohort. In contrast, RECIST1.1 did not show prognostic value for neither early recurrence nor OS.

    头颈部鳞状细胞癌(HNSCC)是一种常见的癌症类型,死亡率高,预后差。最近的研究集中在免疫检查点在HNSCC进展中的作用以及它们作为预后标志物和免疫治疗候选物的潜在用途。一些免疫检查点,如PD-1和PD-L1,已在HNSCC中进行了深入研究。其他分子,如吲哚胺2,3-双加氧酶1(IDO1),已经被最低限度地调查了。
    IDO1表达式,预后潜力,并使用在线数据库探索与HNSCC免疫谱的关联,包括GEPIA,UALCAN,TIMER2.0,cBioPortal,和LinkedOmics,它利用TCGA数据集,可免费使用。出于验证目的,对7对原发性和转移性HNSCC进行IDO1免疫染色。
    我们的分析显示IDO1在HNSCC中的表达明显更高,与健康对照组织相比,尤其是在HPV+SCC中。然而,IDO1表达在HNSCC中显示出整体和无病存活的弱至无预后潜力。HNSCC中IDO1的表达与几种免疫相关分子呈正相关,包括大部分的免疫检查点.此外,GO富集分析显示,HNSCC中几种免疫相关通路与IDO1表达呈正相关,例如对I型干扰素和淋巴细胞介导的免疫途径的反应。最后,IDO1的表达与HNSCC中大多数免疫细胞的浸润呈正相关,如CD4+T细胞,CD8+T细胞,M1和M2巨噬细胞,树突状细胞,B细胞。
    IDO1表达与HNSCC的免疫谱密切相关。应该进一步探索这一观察结果以阐明靶向IDO1作为HNSCC的新型免疫治疗方法的潜力。
    UNASSIGNED: Head and neck squamous cell carcinoma (HNSCCs) is a common cancer type with a high mortality rate and poor prognosis. Recent studies have focused on the role of immune checkpoints in HNSCC progression and in their potential use as prognostic markers and immunotherapeutic candidates. Some immune checkpoints, such as PD-1 and PD-L1, have been studied thoroughly in HNSCC. Other molecules, such as indoleamine 2,3-dioxygenase 1 (IDO1), have been investigated minimally.
    UNASSIGNED: IDO1 expression, prognostic potential, and association with the immune profile of HNSCC were explored using online databases, including GEPIA, UALCAN, TIMER2.0, cBioPortal, and LinkedOmics, which utilize TCGA datasets and are freely available for use. For validation purposes, seven pairs of primary and metastatic HNSCC were immunostained for IDO1.
    UNASSIGNED: Our analysis revealed significantly higher expression of IDO1 in HNSCC, especially in HPV+ SCCs compared with healthy control tissue. However, IDO1 expression showed weak to no prognostic potential for overall and disease-free survival in HNSCC. IDO1 expression in HNSCC was positively correlated with several immune-related molecules, including most of the immune checkpoints. Additionally, GO enrichment analysis revealed that several immune-related pathways are positively correlated with IDO1 expression in HNSCC, such as response to type I interferon and lymphocyte-mediated immunity pathways. Finally, IDO1 expression positively correlated with infiltration of most of the immune cells in HNSCC, such as CD4+ T cells, CD8+ T cells, M1 and M2 macrophages, dendritic cells, and B cells.
    UNASSIGNED: IDO1 expression is closely correlated with the immune profile of the HNSCC. This observation should be explored further to elucidate the potential of targeting IDO1 as a novel immunotherapeutic approach for HNSCC.

    CSMD2已被报道为几种癌症的潜在预后因素。然而,CSMD2是否影响膀胱癌(BC)尚不清楚.
    公开数据来自TCGA(https://cancergenome。nih.gov)数据库。使用生物信息学方法分析CSMD2的表达及其预后价值。通过定量逆转录酶聚合酶链反应评估BC和BC细胞系患者的CSMD2mRNA水平。通过免疫组织化学评估BC患者的CSMD2蛋白水平。选择BC细胞系T24和UMUC-3用于靶向CSMD2的功能丧失测定。通过CCK8和克隆形成实验确定细胞活力。使用Transwell测定法评估细胞迁移和侵袭。此外,对具有CSMD2敲低的UMUC-3转录组进行测序,以分析潜在的信号网络通路.最后,我们利用TIMER2.0数据库鉴定CSMD2与肿瘤微环境中免疫细胞之间的相关性.
    CSMD2表达在BC组织中与邻近组织相比上调。CSMD2高表达与低生存率相关,可作为BC患者生存率的独立预测因子。此外,CSMD2的下调显著抑制了生存能力,迁移,T24和UMUC-3细胞的侵袭能力。此外,在UMUC-3细胞中CSMD2敲低后的转录组测序显示其参与了BC中恶性表型的调节。最后,公共数据库提示CSMD2与BC中免疫细胞浸润之间存在联系.
    这些发现表明CSMD2可能促进增殖和致瘤性,并可能成为改善BC预后的潜在目标。
    UNASSIGNED: CSMD2 has been reported as a potential prognostic factor in several cancers. However, whether CSMD2 affects bladder cancer (BC) remains unclear.
    UNASSIGNED: Public data were obtained from the TCGA (https://cancergenome.nih.gov) databases. CSMD2expression and its prognostic value were analyzed using bioinformatics methods. CSMD2 mRNA level in patients with BC and BC cell lines was evaluated via quantitative reverse transcriptase polymerase chain reaction. CSMD2 protein level in patients with BC was evaluated via immunohistochemistry. BC cell lines T24 and UMUC-3 were selected for loss-of-function assays targeting CSMD2. Cell viability was determined by CCK8 and clone formation experiments. Cell migration and invasion were evaluated using Transwell assays. Furthermore, the transcriptome of UMUC-3 with CSMD2 knockdown was sequenced to analyze potential signaling network pathways. Finally, the TIMER2.0 database was employed to identify the correlation between CSMD2 and immune cells in the tumor microenvironment.
    UNASSIGNED: CSMD2 expression was up-regulated in BC tissues compared to adjacent tissues. High CSMD2 expression was associated with poor survival and could serve as an independent predictor for survival in patients with BC. Furthermore, down-regulation of CSMD2 notably restrained the viability, migration, and invasion abilities of T24 and UMUC-3 cells. Moreover, transcriptomic sequencing after CSMD2 knockdown in UMUC-3 cells revealed its involvement in the regulation of the malignant phenotype in BC. Finally, public databases suggest a connection between CSMD2 and immune cell infiltration in BC.
    UNASSIGNED: These findings suggest that CSMD2 may promote proliferation and tumorigenicity, and could represent a potential target for improving the prognosis of BC.

    背景:乳腺癌(BC),一种异质性疾病,是全球女性癌症相关死亡的主要原因之一。循环无细胞DNA(cfDNA)水平在BC患者中一直被报道升高。在目前的研究中,我们评估了BC患者cfDNA水平与其亚型之间的相关性.
    方法:我们招募了新诊断,经组织病理学证实的年龄>18岁的BC患者(N=39),以前没有任何恶性肿瘤,来自肿瘤外科,英迪拉·甘地医学科学研究所(IGIMS),巴特那,比哈尔邦,印度。从每个受试者中收集总共6ml静脉血;其中,1毫升进行全血细胞计数(CBC),并将4ml转移至凝块活化的收集瓶中用于血浆分离及其cfDNA分离。除了每个患者的基本人口统计学病史,有关癌症亚型的信息也记录在每位患者的医疗记录中.所有数据均由GraphPadPrism版本8(洞察力科学,LLC,圣地亚哥,加州,美国)。使用单因素方差分析来检验多于两组之间的差异。还估计了cfDNA水平和各种CBC指数之间的皮尔逊相关性。双尾p值<0.05被认为是统计学上显著的。
    结果:纳入患者的平均年龄为48.6±8.20岁。cfDNA的平均水平为2.81±2.39ng/µL。各种血细胞类型的平均计数和CBC的其他指标在正常范围内。与雌激素受体(ER)的BC患者相比,在人表皮生长因子受体2(HER2+)和三阴性BC(TNBC)患者中,cfDNA水平显著升高(p<0.05).结论:BC患者cfDNA水平的升高可能是该疾病亚型的预后指标。然而,我们需要更多的复制性研究来证实我们的发现.
    BACKGROUND: Breast cancer (BC), a heterogeneous disease, is one of the leading causes of cancer-related deaths among women worldwide. Circulating cell-free DNA (cfDNA) levels have been persistently reported to be elevated in BC patients. In the current study, we evaluated the correlation between the cfDNA levels in patients with BC and its subtypes.
    METHODS: We recruited newly diagnosed, histopathologically confirmed BC patients aged >18 years (N=39), who did not have any previous malignancy, from the Department of Surgical Oncology, Indira Gandhi Institute of Medical Sciences (IGIMS), Patna, Bihar, India. A total of 6 ml of venous blood was collected from each subject; of this, 1 ml was subjected to complete blood count (CBC), and 4 ml was transferred to a clot-activated collection vial for plasma separation and the cfDNA isolation thereof. In addition to the basic demographic history of each patient, the information on the cancer subtype was as also recorded from the medical records of each patient. All the data were analysed by GraphPad Prism Version 8 (Insightful Science, LLC, San Diego, California, United States). One-way ANOVA was used to test the difference between more than two groups. Pearson correlation was also estimated between cfDNA levels and various CBC indices. A two-tailed p-value<0.05 was considered statistically significant.
    RESULTS: The mean age of included patients was 48.6±8.20 years. The mean levels of cfDNA were 2.81±2.39 ng/µL. The mean counts of various blood cell types and other indices of CBC were in the normal range. Compared to BC patients with estrogen receptors (ER+), the cfDNA levels were significantly higher in patients with human epidermal growth factor receptor 2 (HER2+) and triple-negative BC (TNBC) (p<0.05).  Conclusion: The elevated levels of cfDNA in patients with BC can be a prognostic marker for the disease subtype. However, more replicative studies are warranted to substantiate our findings.

    背景:本研究的目的是探讨胸苷激酶1(TK1)水平在肝细胞癌(HCC)预后中的作用,并建立预测HCC预后的列线图。
    方法:在本研究中,在2018年8月至2022年4月之间招募了1066名HCC患者。在入组前一周内测量TK1水平,并评价其与HCC预后的关系。接下来,所有患者都被随机分配到训练组(70%,n=746)和验证集(30%,n=320)。我们使用多变量Cox分析在训练集中找到独立的预后因素以构建列线图。使用受试者工作特征(ROC)曲线评估列线图的预测能力,校正曲线,和决策曲线分析(DCA)。使用X-tile软件确定TK1的最佳临界值为2.35U/L。
    结果:倾向评分匹配(PSM)前后,低TK1组(<2.35U/L)的中位总生存期(mOS)明显长于高TK1组(≥2.35U/L)(48.1vs16.5个月,p<0.001;75.7对19.8个月,p=0.001)。此外,多因素Cox分析显示,低TK1水平是独立的阳性预后指标。此外,预测1年的ROC曲线下的面积,2年,3年生存率分别为0.770、0.758和0.805。
    结论:TK1可作为HCC的预后标志物。此外,列线图显示对HCC预后具有良好的预测能力.
    BACKGROUND: The aim of this study was to investigate the role of thymidine kinase 1 (TK1) levels in hepatocellular carcinoma (HCC) prognosis and to develop a nomogram for predicting HCC prognosis.
    METHODS: In this study, 1066 HCC patients were enrolled between August 2018 and April 2022. TK1 levels were measured within one week before enrollment, and the relationship with HCC prognosis was evaluated. Next, all patients were randomly assigned to the training set (70%, n = 746) and the validation set (30%, n = 320). We used multivariate Cox analysis to find independent prognostic factors in the training set to construct a nomogram. The predictive power of the nomogram was assessed using receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis (DCA). The optimal critical value of TK1 was determined as 2.35 U/L using X-tile software.
    RESULTS: Before and after propensity score matching (PSM), the median overall survival (mOS) of the low-TK1 group (< 2.35 U/L) remained significantly longer than that of the high-TK1 group (≥ 2.35 U/L) (48.1 vs 16.5 months, p < 0.001; 75.7 vs 19.8 months, p = 0.001). Moreover, multivariate Cox analysis showed that the low TK1 level was an independent positive prognostic indicator. Additionally, the area under the ROC curve for predicting the 1-year, 2-year, and 3-year survival rates was 0.770, 0.758, and 0.805, respectively.
    CONCLUSIONS: TK1 could serve as a prognostic marker for HCC. In addition, the nomogram showed good predictive capability for HCC prognosis.

    Glioblastoma is the most common aggressive primary central nervous system cancer in adults characterised by uniformly poor survival. Despite maximal safe resection and postoperative radiotherapy with concurrent and adjuvant temozolomide-based chemotherapy, tumours inevitably recur. Imaging with O-(2-[18F]-fluoroethyl)-L-tyrosine (FET) positron emission tomography (PET) has the potential to impact adjuvant radiotherapy (RT) planning, distinguish between treatment-induced pseudoprogression versus tumour progression as well as prognostication.
    The FET-PET in Glioblastoma (FIG) study is a prospective, multicentre, non-randomised, phase II study across 10 Australian sites and will enrol up to 210 adults aged ≥18 years with newly diagnosed glioblastoma. FET-PET will be performed at up to three time points: (1) following initial surgery and prior to commencement of chemoradiation (FET-PET1); (2) 4 weeks following concurrent chemoradiation (FET-PET2); and (3) within 14 days of suspected clinical and/or radiological progression on MRI (performed at the time of clinical suspicion of tumour recurrence) (FET-PET3). The co-primary outcomes are: (1) to investigate how FET-PET versus standard MRI impacts RT volume delineation and (2) to determine the accuracy and management impact of FET-PET in distinguishing pseudoprogression from true tumour progression. The secondary outcomes are: (1) to investigate the relationships between FET-PET parameters (including dynamic uptake, tumour to background ratio, metabolic tumour volume) and progression-free survival and overall survival; (2) to assess the change in blood and tissue biomarkers determined by serum assay when comparing FET-PET data acquired prior to chemoradiation with other prognostic markers, looking at the relationships of FET-PET versus MRI-determined site/s of progressive disease post chemotherapy treatment with MRI and FET-PET imaging; and (3) to estimate the health economic impact of incorporating FET-PET into glioblastoma management and in the assessment of post-treatment pseudoprogression or recurrence/true progression. Exploratory outcomes include the correlation of multimodal imaging, blood and tumour biomarker analyses with patterns of failure and survival.
    The study protocol V.2.0 dated 20 November 2020 has been approved by a lead Human Research Ethics Committee (Austin Health, Victoria). Other clinical sites will provide oversight through local governance processes, including obtaining informed consent from suitable participants. The study will be conducted in accordance with the principles of the Declaration of Helsinki and Good Clinical Practice. Results of the FIG study (TROG 18.06) will be disseminated via relevant scientific and consumer forums and peer-reviewed publications.

    背景:血清铁蛋白水平与心力衰竭(HF)的高风险相关。血清铁蛋白水平,增加或减少,预测慢性心力衰竭(CHF)患者的死亡风险尚不清楚.目的:本研究旨在阐明血清铁蛋白水平在评估慢性心力衰竭(CHF)危重患者短期死亡率中的潜在预测意义。方法:从重症监护III和IV(MIMICIII和IV)数据库中的多参数智能监测中确定患有CHF的重症患者。线性和逻辑回归模型以及Cox比例风险模型用于评估血清铁蛋白与生存率之间的关联。结果:从MIMICIII和IV数据库中确定了总共1,739和2,322例CHF患者,分别,符合纳入标准。在MIMICIII组中,与参考组(血清铁蛋白≥70和<500ng/mL)相比,血清铁蛋白≥1000ng/mL是28天的重要预测因子(比值比[OR],1.76;95%置信区间[CI],1.14-2.72)和90天死亡率(OR,1.64;95%CI,1.13-2.39)。Cox回归和Kaplan-Meier曲线的结果揭示了相似的结果。在MIMICIV组中,血清铁蛋白≥1000ng/mL是住院的重要预测因素(OR,1.70;95%CI,1.18-2.46),28天(或,1.83;95%CI,1.24-2.69),和90天死亡率(OR,1.57;95%CI,1.11-2.22)调整混杂因素后。结论:高铁蛋白水平(≥1000ng/mL)与CHF危重患者的短期死亡率增加有关。表明血清铁蛋白可作为CHF的有用预后标志物。
    Background: Serum ferritin levels are associated with a higher risk of incident heart failure (HF). Whether serum ferritin levels, either increased or decreased, predict the risk of mortality in individuals with chronic heart failure (CHF) remains unknown. Objectives: This study aimed to clarify the potential predictive significance of serum ferritin levels in assessing the short-term mortality in critically ill patients with chronic heart failure (CHF). Methods: Critically ill patients with CHF were identified from the Multiparameter Intelligent Monitoring in Intensive Care III and IV (MIMIC III and IV) databases. Linear and logistic regression models and Cox proportional hazards models were applied to assess the associations between serum ferritin and survival. Results: A total of 1,739 and 2,322 patients with CHF identified from the MIMIC III and IV databases, respectively, fulfilled the inclusion criteria. In the MIMIC III group, compared with the reference group (serum ferritin ≥70 and <500 ng/mL), serum ferritin ≥1000 ng/mL was a significant predictor of 28-day (odds ratio [OR], 1.76; 95% confidence interval [CI], 1.14-2.72) and 90-day mortality (OR, 1.64; 95% CI, 1.13-2.39). The results from the Cox regression and Kaplan-Meier curves revealed similar results. In the MIMIC IV group, serum ferritin ≥1000 ng/mL was a significant predictor of in-hospital (OR, 1.70; 95% CI, 1.18-2.46), 28-day (OR, 1.83; 95% CI, 1.24-2.69), and 90-day mortality (OR, 1.57; 95% CI, 1.11-2.22) after adjusting for confounding factors. Conclusion: High ferritin levels (≥1000 ng/mL) were associated with increased short-term mortality in critically ill patients with CHF, indicating that serum ferritin may serve as a useful prognostic marker for CHF.
