Background. Preeclampsia affects 5-6% of all pregnancies. Predictive factors of preeclampsia can be helpful in early diagnosis of this disease. In this study the predictive values of biochemical markers placenta protein 13 (PP13) and pregnancy-associated plasma protein A (PAPP-A) have been assessed in early diagnosis of preeclampsia. Methods. This case-control study was conducted on 1500 women who presented to a healthcare center of Sari, Iran, between 2010 and 2011. Blood samples were drawn in weeks 11–13 and 24–28 of pregnancy. Of them who developed preeclampsia were considered as case group. A control group consisted of similar women regarding mean age, body mass index (BMI), and pregnancy age. PAPP-A and PP13 serum levels were measured. Data were analyzed using proper statistical tests. Results. PAPP-A and PP13 serum levels were significantly lower in both the first and second trimesters in women who developed preeclampsia (P<0.001). The cumulative value of all four variables with cut-off point of 238.5 has sensitivity, specificity of 91.0%, and undercurve surface of 0.968 which is the most diagnostic value for preeclampsia. Conclusion. It is possible to advantage measuring of PAPP-A and PP13 in the first and second trimesters especially their cumulative values in both trimesters for prediction of the incidence of preeclampsia.

AbstractThe aim of this study was to evaluate the serum NF-κBp65, TLR4 (Toll-like receptor 4) expression in patients of preeclampsia and its diagnostic value as biomarkers.MethodsThirty patients with preeclampsia (case group) and 30 normal pregnant women (control group) were included in this study. The serum level of NF-κBp65 and TLR4 were examined by enzyme linked immunosorbent assay (ELISA), and compared between the two groups. The diagnostic sensitivity, specificity and area under the receiver operating characteristic (ROC) curve were calculated by STATA11.0 statistical software.ResultsThe expression level of TLR4 and NF-κBp65 in serum of preeclampsia patient group was 3.76±1.07ng/ ml and 183.20±49.19ng/ml, whereas that in the serum of the normal pregnant group was 2.43±0.69ng/ml and 98.68±29.80ng/ml. The expression of TLR4 and NF-κBp65 in serum of preeclampsia patient group was significantly higher than that of the normal pregnant group (P<0.05); The Pearson correlation test showed that the TLR4 expression in the serum of preeclampsia patients and normal pregnant women was positively correlated with their NF-κBp65 expression [rpreeclampsia=0.46, (P<0.05), rnormal=0.48, (P<0.05)]. When TLR4 and NF-κBp65 were selected as the reference indexes, the diagnostic sensitivity of preeclampsia was 86.67% (95%CI:69.28%-96.24%) and 90.33% (95%CI:73.47%-97.89%), and the specific ity was 70.00% (95%CI:50.60%-85.27%) and 83.33% (95%CI:65.28%-94.36%). The area under the ROC curve was 0.84 and 0.89.ConclusionSerum levels of TLR4 and NF-κBp65 was significantly higher in patients with preeclampsia which may involve in the pathogenesis of preeclampsia, and can be used as biomarker for predicting preeclampsia.

In this study, we compared the levels of C-C chemokine receptor type 5 (CCR5), C-C motif chemokine ligand 5 (CCL5), platelet-derived growth factor (PDGF), and EphrinA7 (EphA7) in patients with colorectal carcinoma and healthy controls in order to investigate the significance and usability of these potential biomarkers in early diagnosis of colorectal cancer. The study included 70 colorectal carcinoma patients and 40 healthy individuals. The CCR5, CCL5, PDGF, and EphA7 levels were measured using ELISA in blood samples. PDGF-BB, EphA7, CCR5, and CCL5 levels of the patients with colorectal carcinoma were significantly higher compared to the control group (p < 0.001 for each comparison). Our logistic regression analysis (the area under the curve was 0.958) supports the notion that PDGF-BB, EphA7, and CCL5 are potential biomarkers for the diagnosis of colon cancer. The sensitivity, specificity, and positive and negative predictive values were found to be 87.9%, 87.5%, 92.1%, and 81.4%, respectively. To our knowledge, this is the first study that investigates the relationship between colorectal carcinoma and the four biomarkers CCL5, CCR5, PDGF, and EphA7. The significantly elevated levels of all these parameters in the patient group compared to the healthy controls indicate that they can be used for the early diagnosis of colorectal carcinoma.

AbstractBackgroundDepression is a common cause of mortality and morbidity worldwide. To detect depression, we compared Beck Depression Inventory scoring as a valid tool with participants self-reporting depression.MethodologyThis cross-sectional study aimed to explore the diagnostic values of self-reporting in patients’ with depression comparing to Beck Depression Inventory scoring in Mazandaran Persian cohort study, with a total of 1300 samples. The sample size was determined to include 155 participants through the census method. In order to increase the test power, 310 healthy participants were included in the study through random selection. In order to evaluate the diagnostic value of self-reporting, BDI-II was completed by blind interviewing to the case group as well as to another group who reported that they were not depressed, as control.ResultsSensitivity, specificity, accuracy, false positive, false negative, positive and negative predictive values of self-reporting was calculated 58.4%, 79.1%,73.4%, 20.8%, 41.6%, 51.8%, and 83.2% for the total population respectively, as well as, sensitivity, specificity, accuracy, positive and negative predictive values of self-report in males were 83.3%, 77.2%, 77.1%, 43.8% and 95.6% and 53.7%, 78.1%, 71.2%, 49.2%, and 81.1% for females, respectively.ConclusionThe positive predictive value and sensitivity of self-reporting are insufficient in total population and females, and therefore self-reporting cannot detect depressed patients, but regarding to its average positive predictive value, perhaps, it can be used to identify non-depressant individuals.

Abstract Background Objective: To compare the accuracy of Quantiferon ®- TB Gold Plus (QFT-Plus) and T-SPOT.TB in the diagnosis of active tuberculosis (ATB). Methods From April 2020 to May 2021, patients with pathologically confirmed or clinically diagnosed ATB in Peking Union Medical College Hospital and Beijing Chest Hospital were enrolled as case group, while patients excluded from ATB in the same period were enrolled as control group, The clinical and laboratory information were collected. QFT-Plus and T-SPOT. TB were tested simultaneously to evaluate the consistency of the results and compare the sensitivity, specificity, predictive values and likelihood ratios for diagnosing ATB. Results Fifty-seven ATB patients and 159 non-ATB patients were included. 33 (57.9%) ATB patients were pathologically confirmed. The proportions of indeterminate results in QFT-Plus and T-SPOT.TB were 3.7% vs 0%, respectively. The agreement between the results of the QFT-Plus and T-SPOT.TB was substantial (kappa=0.644, p＜0.001). The area under the ROC curve of the QFT-Plus and T-SPOT.TB for diagnosing ATB was 0.759 (95%CI 0.689-0.829) vs 0.810 (95%CI 0.742-0.877), respectively, and there was no significant difference (p=0.303). the sensitivity of the QFT-Plus and T-SPOT.TB was 85.2% vs 89.5%, while the specificity was 61.7% vs 52.2%, respectively. In 33 Patients with pathologically confirmed ATB, the sensitivity of QFT-Plus and T-SPOT.TB was 87.9% vs 93.9% (p=0.669), respectively. In 78 patients (36.1%) who received glucocorticoid / immunosuppressive / biological agents, the positive rate of QFT-Plus was 35.9% (28/78), which was significantly lower than that of those who did not receive these agents (77 / 138pm,55.8%) (p=0.005), but there was no significant difference in the positive rate of T-SPOT.TB between the two groups (52.6% vs. 62.3%, p=0.162). The positive rate for both tests was independent of the peripheral blood lymphocyte count (p=0.675 for QFT-Plus vs. P=0.138 for T-SPOT.TB). Conclusion There was no significant difference between the QFT-Plus and T-SPOT.TB in the diagnosis of ATB. QFT-plus might be prone to indeterminate results and influenced by the immunosuppressive status. The results need to be verified by a prospective cohort study with large sample.

Objectives: Rheumatoid arthritis is a chronic inflammatory autoimmune disease. This study aimed to determine the association of interleukin-17A-197G/A polymorphism with rheumatoid arthritis in Sudanese patients. Methods: A case–control study was conducted between March and December 2018. Clinical and demographic data of the study participants were collected and analyzed. Polymerase chain reaction restriction fragment length polymorphism molecular technique was done to investigate interleukin-17A-197G/A polymorphisms. All statistical tests were considered statistically significant when p < 0.05. Results: The study population included 266 participants aged between 1 and 85 years, with an average of 40 years, classified into 85 (31.2%) cases (mean age 48.5 ± 11.3 years), and 181 (68.8%) controls (mean age 35.3 ± 15.9 years). The interleukin-17A homozygote AA genotype was more frequent among the control group compared to the case group; 95 (52.5%) and 7 (8.2%), respectively. The homozygote GG and the heterozygote AG genotypes were proportionally not different among the cases and control groups; 13 (54.2%) and 11 (45.8%), and 65 (46.4%) and 75 (53.6%), respectively. According to the distribution of interleukin-17A genotypes, a statistically significant difference was observed among cases with the interleukin-17A AA and AG genotypes, p values 0.001 and 0.004, respectively. For the association interleukin-17A genotypes and family history a negatively significant association was reported (95% confidence interval, –0.219, p value = 0.001). There was also a negatively significant association of interleukin-17A genotypes and anti-cyclic citrullinated peptide (95% confidence interval, −0.141, p value = 0.002). Conclusion: This study is the first study in Sudan established the association between interleukin-17A-197G/A (rs2275913) polymorphisms and susceptibly to rheumatoid arthritis. These findings appeal for further research in Sudan to investigate the exact role of IL-17A in immunopathology and disease severity among Sudanese rheumatoid arthritis

Abstract Background Numerous individual studies have investigated the diagnostic value of EBV-DNA, EA-IgA, VCA-IgA, EBNA1-IgA and Rta-IgG detection for nasopharyngeal carcinoma (NPC), but the conclusions remain controversial. This meta-analysis aimed to determine the value of EBV-DNA, EA-IgA, VCA-IgA, EBNA1-IgA and Rta-IgG detection in the diagnosis of NPC. Methods PROSPERO registration number: CRD42019145532. PubMed, EMBASE, Cochrane Library, and Chinese data libraries (Wanfang, CNKI, and CBM) were searched up to January 2019. The pooled sensitivity, specificity, and positive likelihood, negative likelihood, and diagnostic odds ratios were conducted in this meta-analysis. Summary receiver operating characteristic curves evaluated the test-performance global summary. Publication bias was examined by Deek’s funnel plot asymmetry test. Results Forty-seven studies with 8382 NPC patients (NPC group) and 15,089 individuals without NPC (Control group) were included in this meta-analysis. The sensitivity, specificity, positive likelihood (+ LR), negative likelihood (-LR), DOR and AUC of EBV-DNA in diagnosis of NPC were: 0.76 (95% CI 0.73–0.77), 0.96 (95% CI 0.95–0.97), 14.66 (95% CI 9.97–21.55), 0.19 (95% CI 0.13–0.28), 84 (95% CI 50.45–139.88), 0.96 (SE: 0.001), and 0.55 (95% CI 0.54–0.57), 0.96 (95% CI 0.96–0.97), 12.91 (95% CI 9.55–17.45), 0.35 (95% CI 0.29–0.43), 39.57 (95% CI 26.44–59.23), 0.94 (SE: 0.002) for the EA-IgA, and 0.85 (95% CI 0.84–0.85), 0.89 (95% CI 0.88–0.89), 6.73 (95% CI5.38–8.43), 0.17 (95% CI 0.12–0.23), 43.03 (95% CI 31.51–58.76), 0.93 (SE: 0.007) for the VCA-IgA, and 0.86 (95% CI 0.85–0.88), 0.87 (95% CI 0.88–0.90), 7.55 (95% CI 5.79–9.87), 0.16 (95% CI 0.13–0.19), 50.95 (95% CI 34.35–75.57), 0.94 (SE: 0.008) for the EBNA1-IgA, and 0.70 (95% CI 0.69–0.71), 0.94 (95% CI 0.94–0.95), 9.84 (95% CI 8.40–11.54), 0.25 (95% CI 0.21–0.31), 40.59 (95% CI 32.09–51.35), 0.95 (SE: 0.005) for the Rta-IgG. The EBV-DNA had larger AUC compared with other EBV-based antibodies (P < 0.05), while the difference between EA-IgA, VCA-IgA, EBNA1-IgA and Rta-IgG was not statistically significant (P > 0.05). Conclusions EBV-DNA, VCA-IgA, EBNA1-IgA and Rta-IgG detection have high accuracy in early diagnosis NPC. In addition, EBV-DNA detection has the higher diagnosis accuracy in NPC. On the other hand, EA-IgA is suitable for the diagnosis but not NPC screening.

Objective: We aimed to investigate the diagnostic value of the vaginal microecology, serum miR-18a, and programmed death ligand-1 (PD-L1) for human papillomavirus (HPV)-positive cervical cancer. Methods: Eighty-four patients with HPV-positive cervical cancer were assigned to the observation group, 107 HPV-positive patients without cervical cancer were assigned to the positive group, and 191 healthy women were assigned to the control group. Vaginal microecology and serum levels of miR-18a and PD-L1 on the surface of CD4+ and CD8+ T cells were compared among the 3 groups. The observation group was further divided into subgroups according to patients’ characteristics for comparison. The diagnostic value of miR-18a and PD-L1 for HPV-positive cervical cancer was investigated. Results: Women in the control group had better vaginal microecology and lower levels of miR-18a and PD-L1 than those in the observation and the positive groups (all P < 0.05). Compared with the positive group, the observation group had similar vaginal microecology (all P > 0.05) but higher levels of miR-18a and PD-L1 (all P < 0.05). Moreover, the patients at stage III had higher levels of miR-18a and PD-L1 than those at stage I and II (all P < 0.05). The values of area under the curve for miR-18a and PD-L1 in the diagnosis of HPV-positive cervical cancer were over 0.8 (all P < 0.001). Conclusion: Patients with HPV-positive cervical cancer have vaginal microbial dysbiosis and high serum levels of miR-18a and PD-L1. miR-18a and PD-L1 have diagnostic value for identifying HPV-positive cervical cancer.

Abstract Background: Sepsis is a highly complex and fatal syndrome. It is the main cause of death in the intensive care unit. Early diagnosis is beneficial to reduce the mortality of sepsis and improve the prognosis of patients. Therefore, we look forward to finding cheap and fast diagnostic criteria to quickly assess the patient's condition.Methods: This is a retrospective study. The study enrolled 499 patients in the First Affiliated Hospital of Xinjiang Medical University from January 1, 2018 to June 22, 2020, and 96 healthy cases in the same period. Using the diagnostic criteria of bacterial infection, SIRS criteria and Sepsis-2 consensus criteria, 499 patients and 96 healthy cases were divided into 4 groups: sepsis group (n=300), SIRS group (n=151), infection group (n= 48), the control group (n=96). We collected the results of routine laboratory tests, inflammation indicators and blood culture results of these patients. Results: The sepsis group compared with the control group, MCV, NE, WBC, PLT, HB, D-Dimer, PT, CRP, PCT, IL-6, ALB, TBIL, Cr, LAC, CysC and BNP were statistically significant. D-dimer, CRP and PCT have higher diagnostic efficiency. Compared with the difference between the infection group and the SIRS group, PLT and IL-6 are statistically significant, and have a certain diagnostic value. Sepsis group VS infection group, WBC, IL-6, NE and TBIL showed statistical differences in the comparison. The AUC of NE was 67.6, which was the largest among the three. The specificity (95.8%) was the highest, but the sensitivity (49%) was low.Conclusions: This retrospective study shows that NE, WBC, and D-dimer can help in the early diagnosis of sepsis. D-dimer performs best. WBC and NE may have a differential diagnosis significance between the sepsis group and the infection group. This result can provide a timely and convenient assessment tool for early diagnosis of sepsis.
