Background: This study explored the predictive value of postoperative C-reactive protein in children with hypospadias for postoperative complications and the risk factors.Methods: The clinical and follow-up data of 106 children with hypospadias who were treated with operations at Kunming Children's Hospital in 2020 were, respectively, analyzed. According to the occurrence of postoperative complications, the patients were divided into two groups: 25 patients with postoperative complications were the complications group, and 81 without postoperative complications were the control group. The baseline data, clinical characteristics, laboratory test indexes, and outcome of the two groups were collected. Receiver operating characteristic (ROC) was used to calculate the optimal cutoff value of C-reaction protein (CRP). Logistic regression was used to analyze the risk factors of hypospadias after surgery. A probability value (P) < 0.05 was considered statistically significant.Results: According to the result of the ROC curve, the optimal cutoff value of CRP was 11.7 mg/L. Logistic regression showed that the length of urethral defect, the urethral material, the operative produce, and the postoperative CRP level were related to the occurrence of postoperative complications of patients with DCC. The length of the urethral defect and the CRP level were the independent risk factors of the prognosis of hypospadias patients. The CRP level was related to the occurrence of postoperative complications and fistula.Conclusions: Postoperative CRP level can be used as a reliable marker for predicting the prognosis of hypospadias patients.

Abstract Background Postoperative complications have been linked to the morbidity and mortality of several cancers. However, predicting whether complications will occur in the early period after surgery or not is challenging. Hence, this study aimed to examine the diagnostic accuracy of serum creatine phosphokinase (CPK) and c-reactive protein (CRP) in predicting the development of postgastrectomy complications. Methods We retrospectively analyzed 188 patients with gastric cancer (GC) who underwent gastrectomy. The diagnostic accuracy of serum CPK and CRP was investigated using the areas under the curves (AUC). The CPK ratio was defined as the CPK on postoperative day (POD) 1 to the CPK on a preoperative day. Results Out of 188 patients, 48 (25.5%) developed postoperative complications. The complications group had a greater operative time (p = 0.037), higher CPK ratio on POD1 (p < 0.0001), and a higher serum CRP level on POD3 (p = 0.001). The AUC for the CPK ratio was 0.772, with an optimal cutoff value of 7.05, whereas that for CRP was 0.659, with an optimal cutoff value of 11.4 mg/L. The CPK ratio on POD1 (p < 0.0001) and the CRP on POD3 (p = 0.007) were independent factors for predicting the development of postgastrectomy complications. The CPK ratio on POD1 and the CRP on POD3 predicted postgastrectomy complications in 41 patients (85.4%). According to combined value of both CPK ratio and CRP level, the positive predictive value and the negative predictive value was 0.70 and 0.829. And sensitivity and specificity were 0.438 and 0.936. Conclusion The CPK ratio on POD1 and the CRP on POD3 after gastrectomy for GC were predictive factors for complication development and may be employed to prevent the development of such complications and improve the prognosis of patients with GC.

Objective. To explore the predictive value of mean platelet volume (MPV) and plasma N-terminal probrain natriuretic peptide (NT-ProBNP) combined with a simplified Geneva scale for the prognosis of acute pulmonary embolism (APE). Methods. The clinical data of 68 patients with APE admitted to our hospital from October 2017 to October 2019 were collected. According to the prognosis, the patients were divided into a good prognosis group (n = 45) and a poor prognosis group (n = 23). The clinical data, laboratory clinical indexes, and simplified Geneva scale scores were recorded for the two groups. The risk factors of poor prognosis were analyzed by binary multivariate logistic regression analysis; the predictive ability of each index on the prognosis of patients with APE was analyzed by the ROC curve. Results. The incidences of deep vein thrombosis, diabetes, and hyperlipidemia in the poor prognosis group were higher than those in the good prognosis group ( P < 0.05 ). PLT, platelet distribution width (PDW), MPV, and plasma NT-ProBNP in the poor prognosis group were higher than those in the good prognosis group ( P < 0.05 ). The simplified Geneva scale score of the poor prognosis group was higher than that of the good prognosis group ( P < 0.05 ). PDW, MPV, plasma NT-ProBNP, and simplified Geneva scale were all independent risk factors for the poor prognosis of APE patients ( P < 0.05 ). The AUC of MPV in predicting the prognosis of APE patients was 0.818 (95% CI: 0.712–0.925). When the optimal cutoff value was 0.571, the sensitivity was 77.1%, and the specificity was 80.0%. The AUC of plasma NT-ProBNP in predicting the prognosis of APE patients was 0.762 (95% CI: 0.634–0.891). When the optimal cutoff value was 0.475, the sensitivity was 71.5%, and the specificity was 76.0%. The AUC of the simplified Geneva scale in predicting the prognosis of APE patients was 0.749 (95% CI: 0.618–0.879). When the optimal cutoff value was 0.469, the sensitivity was 82.9%, and the specificity was 64.0%. The AUC of MPV and plasma NT-ProBNP combined with the simplified Geneva scale in predicting the prognosis of APE patients was 0.907 (95% CI: 0.826–0.988). When the optimal cutoff value was 0.726, the sensitivity was 88.6%, and the specificity was 84.0%. Conclusion. MPV, plasma NT-ProBNP, and simplified Geneva scale have a certain predictive value for the prognosis of APE. Compared with a single index, the combination of the three indexes has a significant improvement in predicting the prognosis of APE and has better clinical value.

Objective: To investigate the relationship between serum C-reactive protein (CRP)/albumin (ALB) ratio and complication occurrence in patients with Type-II diabetes mellitus with at least one chronic complication. Methods: The CAR, demographic characteristics, and other parameters of 108 patients with at least one chronic diabetic complication who attended to the internal medicine outpatient clinic between January 1, 2017, and September 1, 2018, were retrospectively evaluated. Healthy control subjects who did not have any systemic or infectious diseases were also included in the study. I compared the CAR, demographics, and other blood parameters between the two groups were compared. Results: The mean CAR levels were significantly higher in diabetic patients with at least one complication compared to the control group (0.15 [0.07 - 0.29] vs 0.07 [0.07 - 0.07], respectively, p<0.001). There was no significant correlation between CAR and diabetic complications, including neuropathy, nephropathy, coronary artery disease, and retinopathy in the patient group (p>0.05 for all). In the receiver operating curve (ROC) analysis, there was no significant cut-off point for CAR predicting diabetic complications. Conclusions: Although serum CAR levels were significantly higher in complicated diabetic patients compared to controls, any validated CAR value for predicting diabetic complications were not observed. doi: https://doi.org/10.12669/pjms.35.6.618 How to cite this:Bayrak M.

Background: The novel coronavirus disease 2019 (COVID-19) outbreak presents a significant threat to global health. A better understanding of patient clinical profiles is essential to drive efficient and timely health service strategies. In this study, we aimed to identify risk factors for a higher susceptibility to symptomatic presentation with COVID-19 and a transition to severe disease. Methods: We analysed data on 2756 patients admitted to Chelsea & Westminster Hospital NHS Foundation Trust between 1st January and 23rd April 2020. We compared differences in characteristics between patients designated positive for COVID-19 and patients designated negative on hospitalisation and derived a multivariable logistic regression model to identify risk factors for predicting risk of symptomatic COVID-19. For patients with COVID-19, we used univariable and multivariable logistic regression to identify risk factors associated with progression to severe disease defined by: 1) admission to the hospital AICU, 2) the need for mechanical ventilation, 3) in-hospital mortality, and 4) at least one measurement of elevated D-dimer (equal or superior to 1,000 ug/L) indicative of increased risk of venous thromboembolism. Results: The patient population consisted of 1148 COVID-19 positive and 1608 COVID-19 negative patients. Age, sex, self-reported ethnicity, C-reactive protein, white blood cell count, respiratory rate, body temperature, and systolic blood pressure formed the most parsimonious model for predicting risk of symptomatic COVID-19 at hospital admission. Among 1148 patients with COVID-19, 116 (10.1%) were admitted to the AICU, 71 (6.2%) required mechanical ventilation, 368 (32.1%) had at least one record of D-dimer levels ≥1,000 μg/L, and 118 patients died. In the multivariable logistic regression, age (OR = 0.953 per 1 year, 95% CI: 0.937-0.968) C-reactive protein (OR = 1.004 per 1 mg/L, 95% CI: 1.002-1.007), and white blood cell counts (OR = 1.059 per 109/L, 95% CI: 1.010-1.111) were found to be associated with admission to the AICU. Age (OR = 0.973 per 1 year, 95% CI: 0.955-0.990), C-reactive protein (OR = 1.003 per 1 mg/L, 95% CI: 1.000-1.006) and sodium (OR = 0.915 per 1 mmol/L, 0.868-0.962) were associated with mechanical ventilation. Age (OR = 1.023 per 1 year, 95% CI: 1.004-1.043), CRP (OR = 1.004 per 1 mg/L, 95% CI: 1.002-1.006), and body temperature (OR = 0.723 per 1oC, 95% CI: 0.541-0.958) were associated with elevated D-dimer. For mortality, we observed associations with age (OR = 1.060 per 1 year, 95% CI: 1.040-1.082), female sex (OR = 0.442, 95% CI: 0.442, 95% CI: 0.245-0.777), Asian ethnic background (OR = 2.237 vs White ethnic background, 95% CI: 1.111-4.510), C-reactive protein (OR = 1.004 per 1 mg/L, 95% CI: 1.001-1.006), sodium (OR = 1.038 per 1 mmol/L, 95% CI: 1.001-1.006), and respiratory rate (OR = 1.054 per 1 breath/min, 95% CI: 1.024-1.087). Conclusion: Our analysis suggests there are several demographic, clinical and laboratory findings associated with a symptomatic presentation of COVID-19. Moreover, significant associations between patient deterioration were found with age, sex and specific blood markers, chiefly C-reactive protein, and could help early identification of patients at risk of poorer prognosis. Further work is required to clarify the extent to which our observations are relevant beyond current settings.

Abstract Background The effects of matrix metalloproteases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) expressions on the patients with constrictive pericarditis undergoing pericardiectomy remain unclear. This study explored the associations of MMPs and TIMPs expressions with postoperative outcomes in these patients. Methods Pericardial specimens were obtained during pericardiectomy from the patients with constrictive pericarditis. The levels of MMP1, MMP2, MMP9 and TIMP1 in pericardium were analyzed by quantitative real-time polymerase chain reaction. The enrolled patients were divided into two groups according to the optimal cutoff value of gene expression predicting postoperative complications. Postoperative outcomes were compared between the two groups. Binary logistic regression analysis was performed to determine the degree of contribution of gene expression on postoperative outcomes. Results A total of 22 patients and their pericardial specimens were included. The level of MMP9 was significantly associated with postoperative complications and the optimal cutoff value predicting postoperative complications was 3.67. The patients with low level of MMP9 (< 3.67) had lower incidence of postoperative complications (P = 0.002), shorter postoperative intensive care unit (P = 0.040) and hospital stay (P = 0.043) in comparison to those with high level of MMP9 (≥ 3.67). Binary logistic regression analysis showed that high level of MMP9 increased risk of postoperative complications (OR, 27.096, 95%CI 1.166-629.886, P = 0.040). Conclusions High level of MMP9 in the pericardium was associated with poor postoperative outcomes and was the independent risk factor of postoperative complications. The level of MMP9 could be used as a potential marker for prediction of surgical outcomes.

Abstract Objective The aim of this study was to identify early warning signs for severe coronavirus disease 2019 (COVID-19). Methods We retrospectively analysed the clinical data of 90 patients with COVID-19 from Guanggu District of Hubei Women and Children Medical and Healthcare Center, comprising 60 mild cases and 30 severe cases. The demographic data, underlying diseases, clinical manifestations and laboratory blood test results were compared between the two groups. The cutoff values were determined by receiver operating characteristic curve analysis. Logistic regression analysis was performed to identify the independent risk factors for severe COVID-19. Results The patients with mild and severe COVID-19 had significant differences in terms of cancer incidence, age, pretreatment neutrophil-to-lymphocyte ratio (NLR), and pretreatment C-reactive protein-to-albumin ratio (CAR) ( P =0.000; P =0.008; P=0.000; P =0.000). The severity of COVID-19 was positively correlated with comorbid cancer, age, NLR, and CAR ( P <0.005). Multivariate logistic regression analysis showed that age, the NLR and the CAR were independent risk factors for severe COVID-19 (OR=1.086, P =0.008; OR=1.512, P =0.007; OR=17.652, P =0.001). Conclusion An increased CAR can serve as an early warning sign of severe COVID-19 in conjunction with the NLR and age.

Background:C-reactive protein to albumin ratio (CAR) has emerged as a significant biomarker to evaluate and predict systemic inflammation[1]. However, the role of CAR in patients with axial spondyloarthritis (axSpA) remains unknown.Objectives:The aim of this study was to investigate the relationship between CAR and disease activity of axSpA.Methods:A total of 241 patients and 61 healthy controls from Guangdong Second Provincial General Hospital from December 2015 to August 2019 were retrospectively recruited in this study. Patients were divided into two groups, with 176 patients in remission group (BASDAI<4) and 65 patients in active group (BASDAI≥4). Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), albumin (ALB), CAR, neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) and monocyte-lymphocyte ratio (MLR) were detected. The correlations between CAR, NLR, PLR, MLR and disease activity were analyzed by the Spearman’s correlations analysis. Receiver operation characteristic (ROC) curves were performed to evaluate the discriminative utility of these parameters for disease activity of axSpA. Furthermore, the evaluation of the risk factors of axSpA was conducted using binary logistic regression analysis.Results:CAR, ESR, CRP, NLR, PLR and MLR in axSpA patients were significantly higher than those in the control group (p<0.05 for each), while ALB was significantly lower (p<0.001). Similarly, CAR in remission group was higher than that in control group (p<0.001) and was lower than that in active group (p<0.001). Besides, there were significantly positive correlations between CAR and ESR (r=0.702, P<0.001), CRP (r=0.996, P<0.001), BASDAI (r=0.329, p<0.001) and BASFI (r=0.328, P<0.001). Furthermore, ROC suggested that the area under the curve (AUC) of CAR was 0.701, which was the highest. The optimal cutoff point of CAR was 0.3644, with sensitivity and specificity of 58.5% and 79.0%. Logistic analysis results revealed that elevated CAR and MLR were independent risk factors for axSpA (EXP (B) =15.546, 95%CI: 5.898-40.979, P<0.001; EXP (B) =2.206, 95%CI: 1.077-4.519, P=0.031, respectively).Conclusion:CAR was increased in axSpA patients especially in active group, and significantly correlated with disease activity. CAR may serve as a novel inflammatory marker of monitoring disease activity in patients with axSpA.References:[1]He, Y., et al., Correlation between albumin to fibrinogen ratio, C-reactive protein to albumin ratio and Th17 cells in patients with rheumatoid arthritis.

AbstractAlthough the neutrophil to lymphocyte ratio (NLR) was reported to be a predictive biomarker for clinical outcomes in various types of cancer, including recurrent or metastatic head and neck cancer (R/M HNSCC) treated with nivolumab, the usefulness of the pretreatment C-reactive protein/albumin ratio (CAR) as a prognostic marker remains to be clarified. This study aimed to analyze the clinical usability of the CAR in comparison with that of the NLR. 46 R/M HNSCC patients treated with nivolumab were retrospectively analyzed. The optimal cutoff value for the CAR was calculated using receiver operating characteristic curve analysis. The optimal cutoff value for the CAR was set to 0.30. On multivariate analyses, a high CAR was significantly associated with poor overall survival (adjusted HR, 2.19; 95% CI, 1.42–3.47; p < 0.01) and progression-free survival (adjusted HR, 1.98; 95% CI, 1.38–2.80; p < 0.01). The overall response rate and disease control rate for the high CAR patients were lower than for the low CAR patients. The CAR had significantly higher area under the curve values than the NLR at 2 and 4 months. The pretreatment CAR might be an independent marker for prognosis and efficacy in R/M HNSCC patients treated with nivolumab.

Background: Preterm birth is one of the most important cause of perinatal morbidity and mortality. PROM is defined as spontaneous rupture of membranes before the onset of uterine contraction. Objective of present study was to evaluate the role of CRP as an early predictor of Chorioamnionitis in PPROM.Methods: A prospective study was done on 50 cases with PPROM and 50cases of control group without PPROM. All mothers and babies were observed from the time of admission to the time of discharge.Results: C-reactive protein appears to be the most sensitive acute phase protein; rising of less than 24 hours makes it suitable to serve as a marker for diagnosing an infective process in early stage. On comparing C-reactive protein levels with other laboratory tests and indicators of infection (e.g. total leucocyte count DLC, maternal fever, maternal tachycardia, fetal tachycardia) we found CRP level to be more sensitive (100%) but less specific (69.56%) in identifying clinical Chorioamnionitis. The positive predictive value was 22.22% and negative predictive value was 100%.Conclusions: In cases of PPROM, raised CRP is an early predictor of clinical Chorioamnionitis as well as histological Chorioamnionitis.
