    心房颤动(AF)是ST段抬高型心肌梗死(STEMI)后发生的常见心律失常,可显著影响临床预后。我们调查了患者STEMI后房颤的发生率和预测因素,以及其与主要不良心脑血管事件(MACCE)的关系。
    我们进行了一项回顾性队列研究,包括所有在2016年至2020年期间在代码247下向德黑兰心脏中心就诊并完成1年随访的STEMI患者。根据随访期间房颤的发展情况将患者分为两组,并比较其基线和临床特征.我们使用多变量回归模型来识别MACCE的预测因子。
    在3647名STEMI患者中,84例(2.3%)出现新发房颤(NOAF)。房颤患者明显年龄较大,总胆固醇和低密度脂蛋白胆固醇水平较低,甘油三酯,和血红蛋白,但空腹血糖和肌酐水平较高。房颤患者也更可能有高血压病史,慢性肾脏病(CKD),充血性心力衰竭,和脑血管意外。多变量逻辑回归模型将CHA2DS2-VASc评分和CKD确定为初次经皮冠状动脉介入治疗后NOAF的独立预测因子。此外,房颤组MACCE发生率较高,和AF独立预测MACCE的风险比为2.766。
    CHA2DS2-VASc评分和CKD的存在可以作为STEMI患者NOAF的有用预测因子。早期发现和适当管理对于改善结果至关重要。
    UNASSIGNED: Atrial fibrillation (AF) is a common arrhythmia that occurs following ST-elevation myocardial infarction (STEMI) and can significantly impact clinical outcomes. We investigated the incidence and predictors of AF following STEMI in patients, as well as its association with major adverse cardiac and cerebrovascular events (MACCE).
    UNASSIGNED: We conducted a retrospective cohort study, including all STEMI patients who presented under code 247 to Tehran Heart Center between 2016 and 2020 and completed a 1-year follow-up. Patients were divided into two groups based on the development of AF during follow-up, and their baseline and clinical characteristics were compared. We used multivariable regression models to identify predictors of MACCE.
    UNASSIGNED: Out of 3647 STEMI patients, 84 (2.3%) developed new-onset AF (NOAF). Patients with AF were significantly older and had lower levels of total and low-density lipoprotein cholesterol, triglyceride, and hemoglobin, but higher levels of fasting blood sugar and creatinine. AF patients were also more likely to have a history of hypertension, chronic kidney disease (CKD), congestive heart failure, and cerebrovascular accidents. The multivariable logistic regression model identified the CHA2DS2-VASc score and CKD as independent predictors of NOAF following primary percutaneous coronary intervention. Furthermore, the incidence of MACCE was higher in the AF group, and AF independently predicted MACCE with a hazard ratio of 2.766.
    UNASSIGNED: The CHA2DS2-VASc score and the presence of CKD can serve as useful predictors of NOAF among patients with STEMI. Early detection and appropriate management are crucial to improve outcomes.

    神经危重患者经常表现为昏迷,胃轻瘫,和强烈的分解代谢,导致营养不良的风险增加。建立了营养不良诊断的全球领导力倡议(GLIM)标准,以在不同人群中实现一致的营养不良诊断。这项研究旨在验证GLIM标准在神经危重患者中的并发和预测有效性。共有135名参与者从入院到神经关键单元(NCU)直到出院。将GLIM标准与主观全球评估(SGA)进行比较,敏感性为0.95,特异性为0.69.使用复合不良临床结果评估GLIM标准的预测有效性,包括死亡率和各种主要并发症。中度和重度营养不良的调整风险比分别为2.86(95%CI1.45-5.67)和3.88(95%CI1.51-9.94),分别。营养状况指标的变化,包括骨骼肌和腹部脂肪,对61名参与者在入院后7天内进行了研究,以验证GLIM标准对患者接受标准化营养支持的反应的预测能力.GLIM标准对股直肌厚度和中臂肌围的变化具有统计学上显着的预测有效性。总之,GLIM标准对神经危重患者的营养不良诊断具有很高的敏感性,并表现出良好的预测效度.
    Neurocritically ill patients frequently exhibit coma, gastroparesis, and intense catabolism, leading to an increased risk of malnutrition. The Global Leadership Initiative on Malnutrition (GLIM) criteria for the diagnosis of malnutrition was created to achieve a consistent malnutrition diagnosis across diverse populations. This study aimed to validate the concurrent and predictive validity of GLIM criteria in patients with neurocritical illnesses. A total of 135 participants were followed from admission to the neurocritical unit (NCU) until discharge. Comparing GLIM criteria to the Subjective Global Assessment (SGA), sensitivity was 0.95 and specificity was 0.69. Predictive validity of GLIM criteria was assessed using a composite adverse clinical outcome, comprising mortality and various major complications. Adjusted hazard ratios for moderate and severe malnutrition were 2.86 (95% CI 1.45-5.67) and 3.88 (95% CI 1.51-9.94), respectively. Changes in indicators of nutritional status, including skeletal muscle mass and abdominal fat mass, within 7 days of admission were obtained for 61 participants to validate the predictive capability of the GLIM criteria for the patients\' response of standardized nutritional support. The GLIM criteria have a statistically significant predictive validity on changes in rectus femoris muscle thickness and midarm muscle circumference. In conclusion, the GLIM criteria demonstrate high sensitivity for diagnosing malnutrition in neurocritically ill patients and exhibit good predictive validity.

    目的:确定成人脊柱畸形(ASD)患者基线矢状面失衡严重程度的临床影响。
    方法:我们回顾性回顾了接受≥5级融合的患者,包括骨盆,对于随访≥2年的ASD。使用脊柱侧弯研究学会-施瓦布分类系统,根据术前矢状面失衡的严重程度将患者分为3组:轻度,中度,和严重。比较3组患者术后临床及影像学检查结果。
    结果:最终纳入了259例患者。有42、62和155名轻度患者,中度,和严重的群体,分别。重症组的围手术期手术负担最大。术后,该组还显示最大的骨盆发病率减去腰椎前凸不匹配,表明有纠正不足的倾向。近端交界性脊柱后凸无统计学差异,近端交界失败,或者群体之间的杆状骨折。背痛和脊柱侧弯研究协会22评分的视觉模拟评分在各组之间相似。然而,重度组的末次随访Oswestry残疾指数(ODI)评分明显低于重度组。
    结论:严重矢状面失衡的患者在增加围手术期手术负担的同时,接受更多侵入性手术治疗。所有患者在手术后均表现出显着的放射学和临床改善。然而,关于ODI,严重组的临床结果比其他组稍差,可能是由于纠正不足的比例相对较高。因此,更严格的校正对于实现最佳矢状面对齐是必要的,特别是在有严重基线矢状面失衡的患者中.
    OBJECTIVE: To determine the clinical impact of the baseline sagittal imbalance severity in patients with adult spinal deformity (ASD).
    METHODS: We retrospectively reviewed patients who underwent ≥ 5-level fusion including the pelvis, for ASD with a ≥ 2-year follow-up. Using the Scoliosis Research Society-Schwab classification system, patients were classified into 3 groups according to the severity of the preoperative sagittal imbalance: mild, moderate, and severe. Postoperative clinical and radiographic results were compared among the 3 groups.
    RESULTS: A total of 259 patients were finally included. There were 42, 62, and 155 patients in the mild, moderate, and severe groups, respectively. The perioperative surgical burden was greatest in the severe group. Postoperatively, this group also showed the largest pelvic incidence minus lumbar lordosis mismatch, suggesting a tendency towards undercorrection. No statistically significant differences were observed in proximal junctional kyphosis, proximal junctional failure, or rod fractures among the groups. Visual analogue scale for back pain and Scoliosis Research Society-22 scores were similar across groups. However, severe group\'s last follow-up Oswestry Disability Index (ODI) scores significantly lower than those of the severe group.
    CONCLUSIONS: Patients with severe sagittal imbalance were treated with more invasive surgical methods along with increased the perioperative surgical burden. All patients exhibited significant radiological and clinical improvements after surgery. However, regarding ODI, the severe group demonstrated slightly worse clinical outcomes than the other groups, probably due to relatively higher proportion of undercorrection. Therefore, more rigorous correction is necessary to achieve optimal sagittal alignment specifically in patients with severe baseline sagittal imbalance.

    背景:HCMV在移植受者中引起严重的临床并发症,并可能导致移植物排斥。成功的肾移植在很大程度上依赖于CMV感染的早期预防和诊断。然后在移植前及时进行预防性治疗。尽管大多数急性HCMV感染的肾排斥病例无症状,并且在一到两年后发生,本研究的目的是通过检查东印度队列中的具体临床参数,了解晚期HCMV感染对肾排斥反应的影响.方法:在这项研究中,240名患者在移植后进行了为期五年的研究,他们的数据是从印度东部当地的大都会医院收集的。移植后HCMV阳性和阴性患者均使用潜伏感染的临床参数和病毒载量进行了研究。结果:在研究人群中,发现79名移植后患者为HCMV阳性。其中,13例(16.45%)患者在不到2年内出现肾排斥反应。移植(早期排斥)和22(27.84%)患者在2年后发生肾排斥反应。从操作日期(延迟拒绝)。关于HCMV感染的临床参数评估显示,在早期排斥病例中,发热(p-0.035)和尿路感染(p-0.017)突出,但是在后期的拒绝中,血尿(p-0.032),糖尿病(p-0.005),和肌酐水平变化(p<0.001)与尿路感染(p-0.047)有关。结论:这项研究提供了监测潜伏性CMV感染的有价值的见解,并强调了降低肾脏排斥率的理解以及该领域进一步研究的必要性。
    Background: HCMV causes severe clinical complications in transplant recipients and may lead to graft rejection. Successful renal transplantation heavily relies on the early prevention and diagnosis of CMV infections, followed by prompt prophylactic treatment before transplantation. Despite the majority of renal rejection cases with acute HCMV infections being asymptomatic and occurring one to two years later, the objective of this research was to comprehend the effect of late HCMV infection on renal rejection by examining specific clinical parameters in the Eastern Indian cohort. Method: In this study, 240 patients were studied for five years following transplantation, and their data were collected from the local metropolitan hospital in Eastern India. Both HCMV-positive and -negative post-transplant patients were investigated using the clinical parameters and viral loads for latent infection. Results: Within the studied population, 79 post-transplant patients were found to be HCMV positive. Among them, 13 (16.45%) patients suffered from renal rejection within less than 2 yrs. of transplantation (early rejection) and 22 (27.84%) patients suffered from renal rejection after 2 yrs. from the operation date (late rejection). Assessment of clinical parameters with respect to HCMV infection revealed that in early rejection cases, fever (p-0.035) and urinary tract infection (p-0.017) were prominent, but in late rejection, hematuria (p-0.032), diabetes (p-0.005), and creatinine level changes (p < 0.001) were significant along with urinary tract infection (p-0.047). Conclusions: This study provides valuable insights into monitoring latent CMV infections and highlights the understanding of reducing renal rejection rates and the need for further research in this field.

    神经性厌食症(AN)患者的病前体力活动(PA)与疾病发作/病程之间的联系尚不清楚。目的是评估自我报告的PA作为中位数BMI(%mBMI)和住院时间(LOS)变化的预测因子。通过住院时患有AN的青少年的半结构化访谈评估了五个PA域:1-6年级的病前PA(PA1-6);AN发作前(PA-pre)和AN发作后(PA-post);新的,PA(PA-新)和高强度PA(PA-高)的病理动机。通过饮食失调检查问卷(EDE-Q)测量饮食失调心理病理学,和当前的PA(步骤/天)与加速度。还在健康对照(HCs)中评估了PA1-6。使用逐步向后回归模型,检测了%mBMI变化和LOS的预测因子.与22例HCs相比(年龄=14.7±1.3岁,%mBMI=102.4±12.1),25例AN患者(年龄=15.1±1.7岁,%mBMI=74.8±6.0)报告PA1-6明显更高(中位数,AN=115[四分位距IQR=75;200]minvs.HC=68[IQR=29;105]min;p=0.017)。PA-post比PA-pre高244±323%。PA1-6与PA-pre(p=0.001)直接相关,但与PA-post(p=0.179)或PA-pre到PA-post的变化(p=0.735)无关。较低的基线%mBMI(p=0.001)和较高的PA(p=0.004;r2=0.604)预测较低的mBMI增加。通过较高的PA-pre预测较长的LOS(p=0.003,r2=0.368)。自我报告的PA可能会识别出患有AN的年轻人亚组,在AN的住院治疗期间,其体重增加较少,LOS延长。
    Links between premorbid physical activity (PA) and disease onset/course in patients with anorexia nervosa (AN) remain unclear. The aim was to assess self-reported PA as a predictor of change in percent median BMI (%mBMI) and length of hospital stay (LOS). Five PA domains were assessed via semi-structured interview in adolescents with AN at hospitalization: premorbid PA in school grades 1-6 (PA1-6); PA before AN onset (PA-pre) and after AN onset (PA-post); new, pathological motivation for PA (PA-new); and high intensity PA (PA-high). Eating disorder psychopathology was measured via the Eating Disorder Examination Questionnaire (EDE-Q), and current PA (steps/day) with accelerometry. PA1-6 was also assessed in healthy controls (HCs). Using stepwise backward regression models, predictors of %mBMI change and LOS were examined. Compared with 22 HCs (age = 14.7 ± 1.3 years, %mBMI = 102.4 ± 12.1), 25 patients with AN (age = 15.1 ± 1.7 years, %mBMI = 74.8 ± 6.0) reported significantly higher PA1-6 (median, AN = 115 [interquartile range IQR = 75;200] min vs. HC = 68 [IQR = 29;105] min; p = 0.017). PA-post was 244 ± 323% higher than PA-pre. PA1-6 was directly associated with PA-pre (p = 0.001) but not with PA-post (p = 0.179) or change in PA-pre to PA-post (p = 0.735). Lower %mBMI gain was predicted by lower baseline %mBMI (p = 0.001) and more PA-high (p = 0.004; r2 = 0.604). Longer LOS was predicted by higher PA-pre (p = 0.003, r2 = 0.368). Self-reported PA may identify a subgroup of youth with AN at risk of less weight gain and prolonged LOS during inpatient treatment for AN.

    在重症监护病房(ICU)对细菌性败血症患者进行适当的抗生素治疗仍然是一个挑战。考虑到目前的国际指南建议7天的抗生素治疗足以治疗大多数严重感染,我们的主要结局是根据在血培养(BC)中检测到的细菌的体外敏感性,比较两组脓毒症患者在第7日对初始经验性治疗的临床反应和死亡率--采用适当抗生素治疗(AEAT)和不适当抗生素治疗(IEAT).在2020年至2023年期间入住ICU的成年患者,根据序贯器官衰竭评估(SOFA)评分≥2被诊断为败血症,并伴有可疑或有记录的感染。被选中进行研究。418名患者中,149人(35.6%)在7天内死亡。尽管AEAT组的死亡率较低(30.3%vs.34.2%)和更好的临床改善(52.8%vs.47.4%)在开始经验性抗生素治疗后的第7天,差异无统计学意义。从30%的败血症患者的BCs中分离出致病生物,革兰阴性菌(GNB)占60%的病例,以及主要在IEAT组的BCs中检测到的多药耐药(MDR)或广泛耐药(XDR)细菌。尽管AEAT组在脓毒症发作时的临床特征比IEAT组稍差,AEAT组在脓毒症的第7天和第14天表现出更快的改善。在这项回顾性横断面研究中,AEAT组在败血症发病后第7天的临床反应较好,死亡率较低,但没有显著差异。合并症和细菌病原体的类型也应考虑在内,因为它们也有助于预测最终结果。这些结果证明了每日评估临床因素以更准确地预测败血症患者的临床结果的重要性。
    The appropriate antibiotic treatment of patients with bacterial sepsis in the intensive care unit (ICU) remains a challenge. Considering that current international guidelines recommend 7 days of antibiotic therapy as sufficient for most severe infections, our primary outcome was a comparison of clinical response to initial empirical therapy on day 7 and mortality between two groups of septic patients-with appropriate (AEAT) and inappropriate (IEAT) empirical antibiotic therapy according to the in vitro sensitivity of bacteria detected in a blood culture (BC). Adult patients admitted to the ICU between 2020 and 2023, who were diagnosed with sepsis according to the Sequential Organ Failure Assessment (SOFA) score ≥ 2 in association with a suspected or documented infection, were selected for the study. Of the 418 patients, 149 (35.6%) died within 7 days. Although the AEAT group had a lower mortality rate (30.3% vs. 34.2%) and better clinical improvement (52.8% vs. 47.4%) on day 7 after starting empirical antibiotic therapy, there was no significant difference. A causative organism was isolated from BCs in 30% of septic patients, with gram-negative bacteria (GNB) predominating in 60% of cases, and multidrug-resistant (MDR) or extensively drug-resistant (XDR) bacteria predominantly detected in the BCs of the IEAT group. Although the AEAT group had slightly worse clinical characteristics at the onset of sepsis than the IEAT group, the AEAT group showed faster improvement on days 7 and 14 of sepsis. In this retrospective cross-sectional study, the AEAT group was associated with better clinical response at day 7 after sepsis onset and lower mortality, but without a significant difference. Comorbidities and the type of bacterial pathogen should also be taken into account as they can also contribute to the prediction of the final outcome. These results demonstrate the importance of daily assessment of clinical factors to more accurately predict the clinical outcome of a septic patient.

    宫颈癌是全球女性中第四常见的癌症,是由高危型人乳头瘤病毒(HPV)持续感染引起的。HPV病毒载量,样本中HPVDNA的含量,被认为与宫颈疾病的严重程度有关,和宫颈癌的临床结果。在这次系统审查中,我们搜索了三个数据库(EMBASE,PubMed,WebofScience)以检查宫颈样本中HPV病毒载量与疾病严重程度之间关联的当前证据,以及临床结果。排除非HPV的文章后,宫颈癌,或包含临床结果,包括85项原始研究,涉及173,746名妇女。绝大多数(73/85=85.9%)报告说,较高的病毒载量与较高的疾病严重程度或较差的临床结果相关。几项研究报告要么没有相关性(3/85=3.5%),或相反的相关性(9/85=10.6%);可能的原因是HPV病毒载量水平的不同分类,或使用特定的抽样方法。尽管研究设计和人群存在差异,上述结果表明,HPV病毒载量与临床结果相关,并可能成为宫颈癌治疗选择和疗效监测的重要生物标志物。
    Cervical cancer is the fourth most common cancer in women worldwide and is caused by persistent infection with high-risk types of human papillomavirus (HPV). HPV viral load, the amount of HPV DNA in a sample, has been suggested to correlate with cervical disease severity, and with clinical outcome of cervical cancer. In this systematic review, we searched three databases (EMBASE, PubMed, Web of Science) to examine the current evidence on the association between HPV viral load in cervical samples and disease severity, as well as clinical outcome. After exclusion of articles not on HPV, cervical cancer, or containing clinical outcomes, 85 original studies involving 173 746 women were included. The vast majority (73/85 = 85.9%) reported that a higher viral load was correlated with higher disease severity or worse clinical outcome. Several studies reported either no correlation (3/85 = 3.5%), or the opposite correlation (9/85 = 10.6%); possible reasons being different categorization of HPV viral load levels, or the use of specific sampling methods. Despite variations in study design and populations, the above findings suggest that HPV viral load is correlated to clinical outcome, and may become an important biomarker for treatment selection and response monitoring for cervical cancer.

    动脉僵硬在高危疾病实体中的长期临床效果仍不清楚。使用真实世界的注册表评估了臂踝脉搏波速度(baPWV)的预后意义,该注册表包括接受经皮冠状动脉介入治疗(PCI)的患者。
    在放电前使用baPWV测量动脉刚度。主要结果是净不良临床事件(NACE),定义为全因死亡的复合物,非致死性心肌梗死,非致命性中风,或者大出血.次要结局包括主要不良心脑血管事件(MACCE:全因死亡的复合,非致死性心肌梗死,或非致命性中风),大出血.对结果进行了为期4年的评估。
    根据通过时间依赖性受试者工作特征曲线分析确定的1891cm/s的baPWV截止值,将患者(n=3,930)分为高baPWV和低baPWV组。baPWV与PCI术后4年临床事件呈线性关系.高baPWV组的NACE累积发生率更高,MACCE,大出血.根据多变量分析,高baPWV组的4年NACE风险明显更高(调整后的风险比[HRadj]:1.44;95%置信区间[CI]:1.12-1.85;p=0.004),MACCE(HRadj:1.40;95%CI:1.07-1.83;p=0.015),和大出血(HRadj:1.94;95%CI:1.15-3.25;p=0.012)。
    在接受PCI治疗的患者中,baPWV与长期临床结果显著相关,包括缺血和出血事件,表明其识别高风险表型的价值。
    UNASSIGNED: The long-term clinical effect of arterial stiffness in high-risk disease entities remains unclear. The prognostic implications of brachial-ankle pulse wave velocity (baPWV) were assessed using a real-world registry that included patients who underwent percutaneous coronary intervention (PCI).
    UNASSIGNED: Arterial stiffness was measured using baPWV before discharge. The primary outcome was net adverse clinical events (NACE), defined as a composite of all-cause death, non-fatal myocardial infarction, non-fatal stroke, or major bleeding. Secondary outcomes included major adverse cardiac and cerebrovascular events (MACCE: a composite of all-cause death, non-fatal myocardial infarction, or non-fatal stroke), and major bleeding. The outcomes were assessed over a 4-year period.
    UNASSIGNED: Patients (n = 3,930) were stratified into high- and low-baPWV groups based on a baPWV cut-off of 1891 cm/s determined through time-dependent receiver operating characteristic curve analysis. baPWV was linearly correlated with 4-year post-PCI clinical events. The high baPWV group had a greater cumulative incidence of NACE, MACCE, and major bleeding. According to multivariable analysis, the high baPWV groups had a significantly greater risk of 4-year NACE (adjusted hazard ratio [HRadj]: 1.44; 95% confidence interval [CI]: 1.12-1.85; p = 0.004), MACCE (HRadj: 1.40; 95% CI: 1.07-1.83; p = 0.015), and major bleeding (HRadj: 1.94; 95% CI: 1.15-3.25; p = 0.012).
    UNASSIGNED: In PCI-treated patients, baPWV was significantly associated with long-term clinical outcomes, including ischemic and bleeding events, indicating its value for identifying high-risk phenotypes.

    背景:本研究旨在开发和评估影像组学模型,以预测浆液性卵巢癌(SOC)患者手术前的CD27表达和临床预后。
    方法:我们使用了来自癌症基因组图谱(n=339)和癌症成像档案(n=57)的SOC患者的转录组测序数据和对比增强计算机断层扫描图像,并评估了CD27表达的临床意义和预后价值。选择影像组学特征以创建用于CD27表达预测的递归特征消除-逻辑回归(RFE-LR)模型和最小绝对收缩和选择算子逻辑回归(LASSO-LR)模型。
    结果:肿瘤样本中CD27表达上调,高表达水平被确定为生存的独立保护因素。提取了一组三个和六个影像组学特征来开发RFE-LR和LASSO-LR影像组学模型,分别。两种模型都表现出良好的校准和临床益处,如接收器工作特性(ROC)曲线所确定的,校正曲线,和决策曲线分析。LASSO-LR模型的性能优于RFE-LR模型,由于ROC曲线的曲线下面积(AUC)值(0.829vs.0.736).此外,使用LASSO-LR模型预测60个月后SOC诊断患者的总生存期的影像组学评分的AUC值为0.788.
    结论:我们开发的影像组学模型是预测CD27表达状态和SOC预后的有希望的非侵入性工具。强烈建议使用LASSO-LR模型来评估SOCs在临床应用中的术前风险分层。
    BACKGROUND: This study aimed to develop and evaluate radiomics models to predict CD27 expression and clinical prognosis before surgery in patients with serous ovarian cancer (SOC).
    METHODS: We used transcriptome sequencing data and contrast-enhanced computed tomography images of patients with SOC from The Cancer Genome Atlas (n = 339) and The Cancer Imaging Archive (n = 57) and evaluated the clinical significance and prognostic value of CD27 expression. Radiomics features were selected to create a recursive feature elimination-logistic regression (RFE-LR) model and a least absolute shrinkage and selection operator logistic regression (LASSO-LR) model for CD27 expression prediction.
    RESULTS: CD27 expression was upregulated in tumor samples, and a high expression level was determined to be an independent protective factor for survival. A set of three and six radiomics features were extracted to develop RFE-LR and LASSO-LR radiomics models, respectively. Both models demonstrated good calibration and clinical benefits, as determined by the receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis. The LASSO-LR model performed better than the RFE-LR model, owing to the area under the curve (AUC) values of the ROC curves (0.829 vs. 0.736). Furthermore, the AUC value of the radiomics score that predicted the overall survival of patients with SOC diagnosed after 60 months was 0.788 using the LASSO-LR model.
    CONCLUSIONS: The radiomics models we developed are promising noninvasive tools for predicting CD27 expression status and SOC prognosis. The LASSO-LR model is highly recommended for evaluating the preoperative risk stratification for SOCs in clinical applications.

    背景/目标:在COVID-19大流行期间,医院资源负担,高危COVID-19患者的快速分类变得至关重要,和肺部超声(LUS)成为胸部计算机断层扫描的替代方案,提供速度,非电离,可重复,和床边评估。已经使用了各种LUS评分系统,然而,对于最佳严重程度截止尚无共识。我们使用氧饱和度(SpO2)/部分吸入氧(FiO2)比率作为参考标准,评估了12区LUS评分的性能,以识别患有严重肺部受累的成人COVID-19患者,以定义预测不良结局的最佳临界值。方法:我们在德尔马医院进行了一项单中心前瞻性研究(2020年8月至2021年4月),巴塞罗那,西班牙。入住普通病房或重症监护病房(ICU)后,临床医生对确诊为COVID-19肺炎的成年患者进行了LUS检查.严重肺受累定义为SpO2/FiO2比值<315。根据曝气模式,LUS评分范围为0至36。结果:共纳入248例患者。入院LUS评分在确定SpO2/FiO2比值<315方面表现中等(ROC曲线下面积:0.71;95CI0.64-0.77)。在调整COVID-19危险因素后,入院LUS评分≥17与住院死亡风险增加相关(OR5.31;95CI:1.38-20.4),ICU入院(OR3.50;95CI:1.37-8.94)和需要IMV(OR3.31;95CI:1.19-9.13)。结论:尽管入院LUS评分在识别严重肺部受累方面的表现有限,截止值≥17分与不良结局风险增加相关.并可能在COVID-19肺炎患者的快速分类中发挥作用,预测需要高级护理。
    Background/Objectives: During the COVID-19 pandemic and the burden on hospital resources, the rapid categorization of high-risk COVID-19 patients became essential, and lung ultrasound (LUS) emerged as an alternative to chest computed tomography, offering speed, non-ionizing, repeatable, and bedside assessments. Various LUS score systems have been used, yet there is no consensus on an optimal severity cut-off. We assessed the performance of a 12-zone LUS score to identify adult COVID-19 patients with severe lung involvement using oxygen saturation (SpO2)/fractional inspired oxygen (FiO2) ratio as a reference standard to define the best cut-off for predicting adverse outcomes. Methods: We conducted a single-centre prospective study (August 2020-April 2021) at Hospital del Mar, Barcelona, Spain. Upon admission to the general ward or intensive care unit (ICU), clinicians performed LUS in adult patients with confirmed COVID-19 pneumonia. Severe lung involvement was defined as a SpO2/FiO2 ratio <315. The LUS score ranged from 0 to 36 based on the aeration patterns. Results: 248 patients were included. The admission LUS score showed moderate performance in identifying a SpO2/FiO2 ratio <315 (area under the ROC curve: 0.71; 95%CI 0.64-0.77). After adjustment for COVID-19 risk factors, an admission LUS score ≥17 was associated with an increased risk of in-hospital death (OR 5.31; 95%CI: 1.38-20.4), ICU admission (OR 3.50; 95%CI: 1.37-8.94) and need for IMV (OR 3.31; 95%CI: 1.19-9.13). Conclusions: Although the admission LUS score had limited performance in identifying severe lung involvement, a cut-off ≥17 score was associated with an increased risk of adverse outcomes. and could play a role in the rapid categorization of COVID-19 pneumonia patients, anticipating the need for advanced care.
