Abstract Various biochemical indexes discriminate neoplastic from nonneoplastic ascites. However, within the latter group, the distinction between cirrhotic ascites and ascites caused by hepatocarcinoma (HC) is usually based on liver biopsy or cytology. HC-derived ascites is included in the group of nonneoplastic ascites because it is not associated with peritoneal spreading of neoplastic cells. In 54 cases of cirrhotic ascites and 17 cases of HC ascites, all histologically diagnosed, ascitic pseudouridine concentrations discriminated cirrhotic from HC ascites. For example, using the cutoff value of 4.25 mumol/L (obtained by ROC curve analysis) resulted in a diagnostic sensitivity of 88.2% and a diagnostic specificity of 90.8%. Moreover, in cirrhosis, the ascitic concentrations of pseudouridine were lower than serum concentrations, and the two sets of values were correlated; in HC, however, ascitic pseudouridine concentrations were higher than serum concentrations, and the two were unrelated. These findings strongly suggest that in cirrhotic patients ascitic pseudouridine derives from serum by diffusion, whereas in HC patients the mechanism appears to be more complex.

Background. Inflammation is an important hallmark of cancer. Fibrinogen and albumin are both vital factors in systemic inflammation. This study investigated the prognostic value of the fibrinogen/albumin ratio in HCC patients who underwent curative resection. Methods. HCC patients (n=151) who underwent curative resection were evaluated retrospectively. The optimal cutoff value for the fibrinogen/albumin ratio was selected by receiver operating characteristic (ROC) curve analysis. Correlations between preoperative fibrinogen/albumin ratios and clinicopathologic characteristics were analyzed by χ2 test. The area under the receiver operating characteristic curve (AUC) was calculated to compare the prognostic value of the fibrinogen/albumin ratio with other prognostic scores (neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and albumin-bilirubin (ALBI) score). The overall survival (OS) and time to recurrence (TTR) were assessed by the log-rank test and the Cox proportional hazard regression model. Results. An optimal cutoff value of the preoperative fibrinogen/albumin ratio (0.062) was determined for 151 patients who underwent curative resection for HCC via a ROC curve analysis. Fibrinogen/albumin ratio > 0.062 was significantly associated with microvascular invasion, an advanced BCLC stage, and ALBI grade. Multivariate analyses revealed that fibrinogen/albumin ratio was an independent predictor for OS (P=0.003) and TTR (P=0.035). The prognostic ability of fibrinogen/albumin ratio was comparable to other prognostic scores (NLR, PLR, and ALBI score) by AUC analysis. Patients with a fibrinogen/albumin ratio > 0.062 had lower 1-, 3-, and 5-year OS rates (66.0%, 41.8%, and 28.2% versus 81.9%, 69.3%, and 56.1%, resp., P<0.001) and higher 1-, 3-, and 5-year recurrence rates (60.9%, 79.2%, and 90.5% versus 49.5%, 69.1%, and 77.1%, resp., P=0.008) compared with patients with fibrinogen/albumin ratio ≤ 0.062. Conclusion. The preoperative fibrinogen/albumin ratio is an effective prognostic factor for HCC patients who underwent curative resection. An elevated fibrinogen/albumin ratio significantly correlates with poorer survival and a higher risk of recurrence in HCC patients.

High Sensitive Troponin

Introduction: Isolated high sensitive cardiac troponin T (hsTnT) elevations after vascular surgery are frequent and may lead to over diagnosis of myocardial infarction (MI). The aim of our study was to determine the accuracy of the current hsTnT cut-off value in the setting of acute coronary syndrome (ACS) after vascular surgery. Methods: Between August 2012 and March 2014, we included 337 consecutive patients submitted to arterial vascular surgery for which cardiac perioperative evaluation was requested. Perioperative surveillance included 12-lead electrocardiogram and hsTnT measurements on the three days following surgery. Patients were followed-up by cardiologists until hospital discharge and monitored for ACS. A receiver operating characteristics (ROC) curve analysis was performed to determine the hsTnT cut-off value with better accuracy for the diagnosis of perioperative ACS. Results: Of the 337 patients included, 240 (71.2%) presented hsTnT elevation above the manufacturer-provided cut-off value (0.014 ng/ml), whereas 22 (6.5%) fulfilled criteria for ACS. Median post-operative peak hsTnT of ACS patients were 0.215 ng/ml (IQR 0.043-0.493 ng/ml), versus 0.02 ng/ml (IQR 0.012-0.038 ng/ml) in patients that did not have events (P<0.001). After performing a ROC curve analysis (AUC = 0.876), we found that the manufacture-provided cutoff hsTnT value yielded a sensitivity of 100% and specificity of only 35% for diagnosis of perioperative ACS. A new hsTnT cutoff value of 0.0415 ng/ml was obtained with 86.4% sensitivity and 77% specificity for the diagnosis of perioperative ACS. Ninety-two patients (27.3%) had hsTnT elevations above the proposed new cutoff. Conclusion: A different hsTnT cutoff value of 0.0415 ng/ml is proposed and could be more useful for the diagnosis of perioperative ACS.

Background: Trochlear dysplasia (TD) is the principle anatomic risk factor for patellar instability (PI). The lateral trochlear inclination (LTI) is a quantitative measure of trochlear morphology on axial magnetic resonance imaging (MRI). Threshold values for patients at risk for PI via LTI measurement have ranged from 11o to 17o. Our group recently described a new technique for characterizing LTI by referencing the fully-formed posterior femoral condyles. This novel measurement technique revealed that the historically-used method was comparable in reliability but significantly underestimated TD. Purpose: The purpose of this study was to define, with high specificity, a LTI value cutoff value consistent with patellar instability using the new LTI measurement technique. Methods: MRI scans of 95 patients aged 9 to 18 years treated for PI at our tertiary referral center were compared with a control cohort of 98 age- and gender- matched patients with knee imaging but no clinical evidence of PI. LTI was measured as the angle formed between a line subtended from the cartilaginous surface of the lateral trochlea at its most proximal extent and a line parallel to the fully-formed posterior condyles. Receiver operator characteristic (ROC) curve analysis was conducted to establish a cutoff value with optimal specificity and sensitivity. Results: Average LTI was significantly lower in the study group (5.9±10.4o) than control (18.9±5.8o) (p<0.001). Area under the ROC curve was 0.86. A proposed 8.9o LTI threshold angle achieves good discrimination between the two groups, with specificity of 0.904 and sensitivity of 0.684. Conclusion: Re-examination of previously described threshold values using ROC curve analysis of LTI measured in reference to the posterior condyles found 8.9o as the optimal threshold value to achieve good discrimination between patients with and without PI. The novel technique has previously been established to have excellent intra- and inter-observer reliability and produced significantly lower LTI values than the historically-used technique. Taken in concert, this new cutoff is valuable to improve future clinical decision making in regards to risk stratification, treatment algorithms and research purposes.

Abstract Background Fine-needle aspiration is the gold standard, but malignancy rate of the indeterminate cytology is reported as 20-50 %. We aimed to evaluate the efficacy of shear wave elastography (SWE) added to ultrasonogram in the differential diagnosis of thyroid nodules. Methods We retrospectively reviewed the medical records of 258 consecutive patients. Thyroid nodules were divided in to 4 categoies according to maximum elasticity (EMax) and nodule depth/width (D/W) ratio; Category 1 (EMax ≥42.6 kPa & D/W&lt;0.9), Category 2 (EMax &lt;42.6 kPa & D/W&lt;0.9 ), Category 3 (EMax ≥42.6 kPa & D/W≥ 0.9) and Category 4 (EMax&lt;46.2 kPa & D/W≥ 0.9 ). The cutoff value of EMax was set using ROC curve analysis to predict nodular hyperplasia (NH) from follicular neoplasm (FN). Cutoff value ​​for nodule D/W ratio was set using ROC curve analysis for malignancy. Results NH was the most prevalent pathology group in category 1, FN in category 2 and PTC in category 3. The category 3 demonstrated the highest rate of malignancy (81.8%) and had 55.4% sensitivity and 90% specificity for predicting malignancy. When assessing the benign pathology of NH in follicular patterned lesion, category 1 demonstrated the highest NH prevalence of 88.9% (34/37) and had 73.9% sensitivity and 85.0% specificity. Conclusion The performance for malignancy was highest in category 3 and predictive ability for benign pathology of NH in follicular lesion was highest in category 1. So the information of EMax and nodule D/W ratio was useful to predict the pathology of thyroid nodules

Background: There are very few studies on the comparative diagnostic value of CEA and Ca19.9 in esophageal squamous cell carcinoma (ESCC).Aims and objectives: The aim of the present study was to access the clinical relevance of CEA and CA19.9 in ESCC and to determine whether combined use of these marker could improve diagnostic sensitivity and specificity. Material and Method: Venous blood Samples were collected from total 68 individuals, divided into two categories, group 1 includes 18 healthy individuals and group 2 includes 50 patients with already diagnosed cases of ESCC prior to any treatment. Tests were performed to estimate the value of CEA and Ca19.9. Different statistical analysis has been performed to derive a clinically meaningful value.Results: The mean serum CEA and CA 19.9 levels and also the ratio of CEA/Ca19.9 were higher in patients with ESCC than healthy subjects. In ESCC, the optimal combination of sensitivity and specificity for CEA were determined as 48% and 94% and for CA19.9 were determined as 76% and 72% respectively, whereas combined analysis of CEA/CA19.9 were lower than individual value in patients. Over all accuracy rate was better with CA19. The diagnostic power of CEA and CA19-9 as a screening test for ESCC were assessed by ROC curve analysis. The cut-off value for CEA and CA19-9 in ESCC were found to be 2.9 2 ng/ml and 7.4 ng/ml and were found to be above the cut-off value in 25 (50%) and 42 (84%) of the patients with ESCC respectively.Conclusion: The results of our study indicated that serum CA19.9 has a higher positivity than serum CEA in esophageal cancer. The combined use of CA19-9 and CEA (ratio) could not increase the diagnostic sensitivity in esophageal cancers in our study.

Background: Peripheral artery disease (PAD) patients have a substantially increased risk of mortality and cardiovascular morbidity than those without PAD. However, risk prediction tools have not been established among patients with PAD to identify who is likely destined for adverse clinical outcome. Eicosapentaenoic acid to arachidonic acid (EPA/AA) ratio has emerged as predictor of mortality endpoints in vascular diseases, especially, coronary artery disease and cerebrovascular disease. In contrast, the prognostic value of EPA/AA ratios in patients with PAD is unclear. We sought to examine whether assessment of serum ratio of EPA/AA in patients with PAD due to femoropopliteal artery lesions can predict clinical outcome after endovascular therapy (EVT). Methods: We obtained serum EPA/AA ratio in 132 consecutive patients with PAD due to femoropopliteal artery lesions before EVT. We analyzed the incidence of major adverse event (MAE) including major adverse limb event (MALE) and any-cause death. The clinical characteristics and laboratory variables were compared and analyzed between MAE group and non-MAE group. Cox regression analyses were used for survival tests. Receiver operating characteristics (ROC) curve analysis was used to determine an optimal cutoff value for EPA/AA ratio to predict MAE after EVT. Results: At a median follow-up of 17 months, MALE occurred in 39 patients (29.5%) and 10 patients (7.6%) died. Significantly lower level of preprocedural serum EPA/AA ratio was observed in the MAE group than non-MAE group. Multivariable Cox analysis showed critical limb ischemia (hazard ratio, 2.93; 95% confidence interval [CI], 1.59-5.40; P = 0.001) and preprocedural serum EPA/AA ratio (hazard ratio, 0.08; 95% CI, 0.02-0.43; P = 0.003) were independent predictors of MAE after EVT. The cutoff value of EPA/AA ratio via ROC curve analysis was 0.29 (66.3% sensitivity, 73.5% specificity). Conclusions: Our findings suggest that lower serum EPA/AA ratio is associated with a greater risk of MALE and any-cause death after EVT in patients with PAD due to femoropopliteal artery lesions.

Purpose. The aim of this study was to evaluate the diagnostic and prognostic value of IL-6 and sTREM-1 in the course of SIRS and sepsis in children with reference to routinely used CRP and PCT. Methods. A prospective study included 180 patients at the ages from 2 months to 18 years hospitalized due to fever from November 2015 to January 2017. Forty-nine children without fever hospitalized due to noninfectious causes formed the control group. IL-6 and sTREM-1 serum concentrations were assessed with the enzyme-linked immunosorbent assay method. Results. The mean serum concentrations of all the analyzed biomarkers were statistically significantly higher in the study group compared to the control group. Mean IL-6, sTREM-1, and PCT serum concentrations were statistically significantly higher in the group of patients with SIRS/sepsis compared to the group of feverish patients without diagnosed SIRS (N-SIRS). Based on the ROC curve analysis, it was shown that of all the biomarkers tested, only two—IL-6 and procalcitonin—had potential usefulness in the diagnosis of SIRS/sepsis in children with fever. Conclusion. Elevated levels of IL-6 and PCT are important risk factors for the development of SIRS/sepsis in children with fever. It seems that elevated IL-6 baseline serum level may predict a more severe course of febrile illness in children, because based on the ROC curve analysis, it was found that IL-6 is a statistically significant prognostic marker of prolonged fever≥3 days and prolonged hospitalization>10 days. The assessment of the usefulness of sTREM-1 in the diagnosis of SIRS/sepsis in feverish children requires further research.

Abstract Background: Fine-needle aspiration (FNA) is the first step in the differential diagnosis of thyroid nodules. However, malignancy rate of the indeterminate FNA is reported as 20-50 %. We aimed to evaluate the efficacy of shear wave elastography (SWE), the map of stiffness in the differential diagnosis of the histopathology of thyroid nodules. Methods: We retrospectively reviewed the medical records of 258 consecutive patients who visited the thyroid clinic for thyroid nodules and who underwent SWE before ultrasound-guided FNA and/or core-needle biopsy. We analyzed the EI using the total nodular region of interest method by the Q-Box Trace program. Thyroid nodules were divided in to 4 categoies according to maximum elasticity (EMax) and nodule depth/width (D/W) ratio; Category 1 (EMax ≥42.6 kPa & D/W&lt;0.9), Category 2 (EMax &lt;42.6 kPa & D/W&lt;0.9), Category 3 (EMax ≥42.6 kPa & D/W≥ 0.9) and Category 4 (EMax&lt;46.2 kPa & D/W≥ 0.9). The cutoff value of EMax was set using ROC curve analysis to predict follicular neoplasm (FN) from nodular hyperplasia (NH). Cutoff value ​​for nodule D/W ratio was set using ROC curve analysis to differentiate malignant nodule. Results: FN showed the lowest EMax among all pathologies and lower EMax than NH (p&lt;0.05). FN was distributed mostly in the category 2 (70%) and NH was distributed mainly in the category 1 (73.9%). CLT belonged mostly to the category 1 (57.1%). PTC belonged in majority to the category 3 (58.9%) and the rest.to the category 1 (25%). So NH was the most frequent pathology group in category 1.FN was the most frequent pathology group in the category 2 and PTC was the most frequent pathology group in the category 3. Conclusion: SWE showed characteristic patterns of various pathology groups reflecting the degree of fibrosis and the information of EMax and nodule depth/width (D/W) ratio determining the category was useful to predict the pathology of thyroid nodules along with the advantage of noninvasiveness.

Objective To compare the relationship of the Bayley Scales of Infant and Toddler Development 3rd Edition (K-BSID-III) language score and the Sequenced Language Scale for Infant (SELSI) score and evaluate the sensitivity and specificity of K-BSID-III language score and optimal cutoff value with receiver operator characteristic (ROC) curve analysis in infants and toddlers with delayed language development.Methods A total of 104 children with suspected language developmental delay were included in this retrospective study. Subjects were tested using the K-BSID-III and SELSI and subdivided into several groups according to the severity of language scores. ROC curve analysis was performed to assess K-BSID-III for delayed language development.Results Receptive and expressive language subscales of the K-BSID-III showed markedly significant correlation with the SELSI scores (p<0.001). ROC analysis showed an area under the curve of 0.877 (p<0.001) in SELSI receptive score and 0.935 (p<0.001) in SELSI expressive score. The optimal cutoff value where sensitivity of 85% and specificity of 81% were achieved with the K-BSID-III receptive score was 1.50 (between average and low average) in the SELSI receptive score. The optimal cutoff value where sensitivity of 96% and specificity of 82% were achieved with the K-BSID-III expressive score was also 1.50 in the SELSI expressive score.Conclusion In this study, the correlations between K-BSID-III and SELSI language scores were statistically significant. However, the interpretation should be considered carefully in low average group due to tendency of underestimation of delayed language development.

Objective. We investigated the prognostic impact of C-reactive protein to albumin ratio (CRP/Alb) on the survival outcomes of newly diagnosed glioblastoma multiforme (GBM) patients treated with radiotherapy (RT) and concurrent plus adjuvant temozolomide (TMZ). Methods. The pretreatment CRP and Alb records of GBM patients who underwent RT and concurrent plus adjuvant TMZ were retrospectively analyzed. The CRP/Alb was calculated by dividing serum CRP level by serum Alb level obtained prior to RT. The availability of significant cutoff value for CRP/Alb that interacts with survival was assessed with the receiver-operating characteristic (ROC) curve analysis. The primary endpoint was the association between the CRP/Alb and the overall survival (OS). Results. A total of 153 patients were analyzed. At a median follow-up of 14.7 months, median and 5-year OS rates were 16.2 months (95% CI: 12.5–19.7) and 9.5%, respectively, for the entire cohort. The ROC curve analysis identified a significant cutoff value at 0.75 point (area under the curve: 74.9%; sensitivity: 70.9%; specificity: 67.7%; P<0.001) for CRP/Alb that interacts with OS and grouped the patients into two: CRP/Alb <0.75 (n = 61) and ≥0.75 (n = 92), respectively. Survival comparisons revealed that the CRP/Alb <0.75 was associated with a significantly superior median (22.5 versus 15.7 months; P<0.001) and 5-year (20% versus 0%) rates than the CRP/Alb ≥0.75, which retained its independent significance in multivariate analysis (P<0.001). Conclusion. Present results suggested the pretreatment CRP/Alb as a significant and independent inflammation-based index which can be utilized for further prognostic lamination of GBM patients.
