Pro-cathepsin D as a diagnostic marker in differentiating malignant from benign pleural effusion: A retrospective cohort study
Authors: Choi Hayoung , Ko Yousang , Lee Chang Youl 
Published: August 2020

Abstract
Background: Malignant pleural effusion (MPE) causes substantial symptomatic burden in advanced malignancy. Although pleural fluid cytology is a commonly accepted gold standard of diagnosis, its low diagnostic yield is a challenge for clinicians. The aim of this study was to determine whether pro-cathepsin D can serve as a novel biomarker to discriminate between MPE and benign pleural effusion (BPE).Methods: This study included 81 consecutive patients with exudative pleural effusions who had underwent thoracentesis or pleural biopsy. Pleural fluid and serum were collected as a standard procedure for all individuals at the same time. The level of pro-cathepsin D was measured by the sandwich enzyme-linked immunosorbent assay method.Results: Though there were no significant differences in plasma pro-cathepsin D between the two groups, the level of pleural fluid pro-cathepsin D was signiﬁcantly higher in the MPE group than the BPE group (0.651 versus 0.590 pg/mL, P = 0.034). The discriminative power of pleural fluid pro-cathepsin D for diagnosing MPE was moderate, with 81% sensitivity and 53% specificity at a pro-cathepsin D cut-off ≥0.596 pg/mL (area under the curve: 0.656). Positive and negative predictive values for MPE were 38% and 89%, respectively, with pro-cathepsin D cut-off value (>0.596 pg/mL).Conclusions: The level of pleural fluid pro-cathepsin D was found to be significantly higher in MPE than in BPE. Although results of this study could not support the sole use of pleural fluid pro-cathepsin D to diagnose MPE, pleural fluid pro-cathepsin D can be added to pre-existing diagnostic methods for ruling-in or ruling-out MPE.

Published: August 2020

Abstract
Background

Cartilage destruction is the main characteristic of osteoarthritis (OA), and osteopontin (OPN) is elevated in OA articular cartilage; however, the reason for the increased OPN level is not determined. In addition, Wnt/β-catenin signaling participates in the progression of OA. The aim of the present study was to evaluate whether canonical Wnt signaling could regulate the expression of OPN in human chondrocytes in vitro.

Methods

Human chondrocytes were cultured in vitro, and we first assayed the mRNA levels of OPN and β-catenin in chondrocytes. Next, we performed transient transfection of TCF 4 shRNA into chondrocytes to inhibit TCF 4 expression and explore changes in the OPN level. Then, the Wnt/β-catenin signaling inhibitor Dickkopf-1 (Dkk-1) was incubated with chondrocytes, and we assayed the changes in β-catenin and OPN.

Results

Our results showed that the expression of both β-catenin and OPN was increased in OA chondrocytes, but there were no correlations between β-catenin and OPN expression. TCF4 shRNA downregulated the expression of TCF 4 and OPN in chondrocytes, while after treatment with rDKK-1 at a concentration of 400 ng/ml for 24 h, the mRNA and protein expression of both β-catenin and OPN was significantly decreased in chondrocytes.

Conclusions

Elevated OPN expression might be regulated by the β-catenin/TCF-4 pathway, and the Wnt/β-catenin inhibitor DKK1 could inhibit the expression of β-catenin and OPN in OA chondrocytes.

Abstract
Background: Legal substances use is prevalent in Ethiopia. Substance use can have several health problems that are potentially harmful in educational performance, social issues, psychological and physical well being. This study aimed to know the prevalence of lifetime and last month’s substance use and its associated factors among technical and vocational education and training College students in Ataye town. Methods: An institution-based cross-sectional study conducted from 1 March to last May 2019. Participants selected by using a simple random sampling technique. Data collected by using a structured and pretested self-administered questionnaire. Data collected by five trained diploma nurses with close supervision. Odds ratio with their 95% confidence interval, and p-value less than 0.05 used to declare the statistical significance of associated factors. Results: Four hundred eighty-three individuals participated in the study, which was a response rate of 94%. The prevalence of lifetime legal substance use was 32.5% (95% CI: 28.2, 36.5). The prevalence of last month's legal substances use was 21.9% (95% CI= 18.2, 25.5). Among lifetime legal substance users, the majority (25.5%) chewed khat. The others, (19.5%) drunk alcohol, and, 15.3% smoked cigarettes in a lifetime. Lifetime cannabis and cocaine users were 2.5%, and 7.2% respectively. Among last month's legal substance users, (21.9%) chewed khat followed by alcohol drinking (16.6%), and cigarette smoking (15.3%). In the last month, 1.2% and 3.3% of students used cannabis and cocaine respectively. Multivariate logistic regression showed that being male, having a divorced family, living greater than twenty years in the town, having substance user family members, having intimate friend substance users, and easy availability of substances were independent predictors of lifetime legal substances use. Conclusions: The prevalence of last month and lifetime legal substance use at Ataye Technical and Vocational Education and Training ( TVET ) college students were analogous with most studies done in Ethiopia. It is advisable if furthers emphasis is given for TVET students with the predictor variables.

Published: August 2020

Abstract
Background: Homologous sex chromosomes can differentiate over time because recombination is suppressed in the region of the sex determining locus, leading to the accumulation of repeats, progressive loss of genes that lack differential influence on the sexes and sequence divergence on the hemizygous homolog. Divergence in the non-recombining regions leads to the accumulation of Y or W specific sequence useful for developing sex-linked markers. Here we use in silico whole-genome subtraction to identify putative sex-linked sequences in the scincid lizard Bassiana duperreyi which has heteromorphic XY sex chromosomes. Results: We generated 96.7 x 10 9 150 bp paired-end genomic sequence reads from a XY male and 81.4 x 10 9 paired-end reads from an XX female for in silico whole genome subtraction to yield Y enriched contigs. We identified 7 reliable markers which were validated as Y chromosome specific by polymerase chain reaction (PCR) against a panel of 20 males and 20 females. Conclusions: The sex of B. duperreyi can be reversed by low temperatures (XX genotype reversed to a male phenotype). We have developed sex-specific markers to identify the underlying genotypic sex and its concordance or discordance with phenotypic sex in wild populations of B. duperreyi . Our pipeline can be applied to isolate Y or W chromosome-specific sequences of any organism and is not restricted to sequence residing within single-copy genes. This study greatly improves our knowledge of the Y chromosome in B. duperreyi and will enhance future studies of reptile sex determination and sex chromosome evolution.

Abstract
Background: Performance of urinary cytology is recommended as the part of a standard diagnostic workup and base surveillance regimens in upper tract urothelial carcinoma (UTUC). However, the effect of positive voided urine cytology (VUC) on UTUC prognosis, compared with negative VUC, has not been fully demonstrated. This study aimed to evaluate the impact of preoperative VUC on predicting intravesical recurrence, disease recurrence, and mortality in patients with UTUC who underwent nephroureterectomy (RNU).Methods: Clinicopathological information was collected from 315 UTUC patients treated with RNU. The association between VUC and oncological outcomes was analyzed using the Kaplan–Meier method with log-rank test and Cox proportional hazards regression models. Multiple logistic regression analysis was performed to identify the influence of VUC on tumor grade.Results: Preoperative positive VUC, presenting in 101 patients (32%), was significantly associated with tumor multifocality (P=0.017) and higher tumor grade (P=0.010). On multivariate Cox regression analyses, preoperative positive VUC was an independent prognostic factor of intravesical recurrence-free survival (RFS) (hazard ratio [HR]=2.21, 95% confidence interval [CI] 1.06–4.64; P=0.035), RFS (HR=1.80, 95% CI 1.08–2.99; P=0.023), and cancer-specific survival (CSS) (HR=1.87, 95% CI 1.10–3.18; P=0.020), but not overall survival (HR=1.32, 95% CI 0.80–2.18; P=0.28). Logistic regression analysis revealed that VUC was related to high tumor grade in UTUC (odds ratio=2.23, 95%CI 1.15–4.52).Conclusion: Preoperative positive VUC significantly increases the risk of intravesical recurrence in UTUC patients undergoing RNU. In addition, positive VUC is an adverse predictor of RFS and CSS, which might be due to the association between positive VUC and high tumor grade.

Abstract
BackgroundFrailty is a geriatric syndrome that diminishes potential functional recovery after any surgical procedure. Preoperative surgical risk assessment is crucial to calibrate the risk and benefit of cardiac surgery. The aim of this study was to test usefulness of FRAIL Scale and other surgical-risk-scales and individual features of frailty.MethodsProspective study. From May-2014 to February-2016, we collected 200 patients who underwent aortic valve replacement, either surgically or transcatheter. At 1-year follow-up, quality of life measurements were recorded using the EQ-5D (EuroQol). Univariate and multivariate analyses correlated preoperative condition, features of frailty and predicted risk scores with mortality, morbidity and quality of life at 1 year of follow-up.ResultsMean age 78.2y, 56%male. Mean-preoperative-scores: FRAIL scale 1.5(SD 1.02), STS 2.9(SD 1.13), BI 93.8(SD 7.3), ESlog I 12.8(SD 8.5) and GS 7.3s (SD 1.9). Morbidity at discharge, 6 m and 1 year was 51%, 14% and 28%. Mortality 4%. Survival at 6m/ 1-y was 97% / 88%. Complication-rate was higher in TAVI group due to-vascular complications. Renal dysfunction, anemia, social dependence and GS slower than 7 seconds were associated with morbidity. On multivariate analysis adjusted STS, BI and GS speed were statistically significant. Quality of life at 1-year follow-up adjusted for age and prosthesis type showed a significant association with STS and FRAIL scale scores.ConclusionsFrailty increases surgical risk and is associated with higher morbidity. Preoperative GS slower 7 s, and STS and FRAIL scale scores seem to be reliable predictors of quality of life at 1-year follow-up.

Abstract
Background: This study aimed to analyze and compare the clinical and functional outcomes of distal tibia fractures treated with intramedullary nailing (IMN) using the suprapatellar (SP) and infrapatellar (IP) surgical approaches.Methods: A retrospective analysis was performed in 63 patients with distal fractures that were treated with IMN between August 2014 and August 2018. A total of 27 and 36 patients underwent IMN using the SP and IP techniques, respectively. The surgical time, blood loss, closed reduction rate, rate of adjuvant reduction technique, fracture healing time, and complications were reviewed in this study. Anterior knee pain was assessed using the visual analog scale. The Lysholm Knee Scoring Scale and American Orthopaedic Foot and Ankle Society (AOFAS) scale were used as clinical measurements.Results: A total of 63 patients, with a minimum follow-up of 12 months, were evaluated. The average surgical time, blood loss, rate of adjuvant reduction technique, closed reduction rate, fracture healing time, and Lysholm Knee Scoring Scale score were insignificantly different (P>0.05) between the two groups. However, the SP approach was superior to the IP approach in terms of pain score, AOFAS score, and fracture deformity rate (P<0.05).Conclusions: In the treatment of distal tibia fractures, the SP IMN technique is associated with a significantly higher functional outcome, lower knee pain, and lower rate of fracture deformity than the IP IMN technique.

Abstract
Background: There were scarcely germline variants of familial lung cancer (LC) identified. We conducted an study with whole-exome sequencing of pedigrees with familial lung cancer to analyze the potential genetic susceptibility. Methods: Probands with the highest hereditary background were identified by our large-scale epidemiological study and five ones were enrolled as a learning set. The germline SNPs (single-nucleotide polymorphisms) of other five similar probands, four healthy individuals in the formerly pedigrees and three patients with sporadic LC were used as a validation set, controlled by three healthy individuals without family history of any cancer. The network of mutated genes was generated using STRING-DB and visualized using Cytoscape. Results: Specific and shared somatic mutations and germline SNPs were not the shared cause of familial lung cancer. However, individual germline SNPs showed distinct protein-protein interaction network patterns in probands versus healthy individuals and patients with sporadic lung cancer. SNP-containing genes were enriched in the PI3K/AKT pathway. These results were validated in the validation set. Furthermore, patients with familial lung cancer were distinguished by many germline variations in the PI3K/AKT pathway by a simple SVM classification method. It is worth emphasizing that one person with many germline variations in the PI3K/AKT pathway developed lung cancer during follow-up. Conclusions: The phenomenon that the enrichments of germline SNPs in the PI3K/AKT pathway might be a major predictor of familial susceptibility to lung cancer.

Published: August 2020

Abstract
Background: Growing evidences have revealed that long non-coding RNAs (lncRNAs) including circular RNAs (circRNAs) involve in numerous carcinogenesis. However, the roles of circRNAs in the cancer biology of colorectal cancer (CRC) remain vague. Methods: qRT-PCR and western-blot were used to detecte the circRAE1 levels in CRC tissues and CRC cell lines.,Cell proliferation, migration and invasion were detected using wound healing assays, and transwell assays. The interaction between circRAE1 and miR-338-3p and TRYO3 was confirmed by dual-luciferase reporter assays. Results: We uncovered that a novel circRNA Hsa_circ_0060967 (also known as circRAE1) was remarkably increased in CRC tissues, and high circRAE1 level was positively associated with advanced tumor stage, lymph node metastasis, and tumor size. Loss-of-function assay indicated that circRAE1 accelerated cell proliferation, migration and invasion. Besides, miR-338-3p , lowly expressed in CRC tissues and CRC cell lines. dual-luciferase reporter assays showed that circRAE1 could sponge miR-338-3p, which targeted TRYO3 in CRC cells. Furthermore, overexpression of circRAE1 could recue the impaired migration and invasion triggered by miR-338-3p mimics or si-TYRO3 in CRC cells and vice versa. Conclusion : we figured out the network of circRAE1, miR-338-3p, and TYRO3 in CRC cells and revealed that increased circRAE1 served as an oncogene through sponging miR-338-3p, resulting in upregulated TYRO3 expression, which suggested that circRAE1 would be a potential therapeutic target and diagnostic marker for CRC treatment.

Published: August 2020

Abstract
Background: The postoperative nursing intervention with immediate cryotherapy and continuous passive motion (CPM) remains elusive regarding the postoperative pain and range of motion (ROM) for patients undergoing computer-assisted total knee arthroplasty (CAS-TKA).Methods: A prospective, randomized controlled trial with a purposive sampling method was utilized. Sixty patients scheduled for a unilateral CAS-TKA at a medical center were randomly assigned to the intervention group (n=30) and control group (n=30). The intervention group applied programed cryotherapy and CPM within one hour while returning to the ward on the day of surgery, while the control group did not. Data were analyzed using mixed models to compare the numeric rating scale (NRS) for pain, ROM, and swelling at postoperative day (POD) 4.Results: There was no significant difference in the NRS score between the groups (p = 0.168). The intervention group had significantly higher ROM than the control group (98 degrees vs. 91 degrees, p = 0.004) at POD 4. Although no significant difference in joint swelling was found between groups (p = 0.157), the intervention group had lower mean joint swelling (32.2 cm) than the control group (33.9 cm).Conclusions: Immediate programmed cryotherapy and continuous passive motion could help to improve ROM quickly after CAS-TKA. It should be incorporated into the daily nursing plan for patients undergoing CAS-TKA.Trial registration: ClinicalTrials.gov: NCT04136431.

Published: August 2020

Abstract
Background: The E2F family of transcription factor 2 (E2F2) plays an important role in the development and progression of various tumors, but its association with hepatocellular carcinoma remains unknown. The aim of our study was to investigate the role and clinical significance of E2F2 in hepatocellular carcinoma (HCC).Methods: HCC raw data were extracted from The Cancer Genome Atlas (TCGA). Wilcoxon signed-rank test, Kruskal-Wallis test and logistic regression was applied to analyze the relationship between the expression of E2F2 and clinicopathologic characteristics. Cox regression and Kaplan-Meier was employed to evaluate the correlation between clinicopathologic features and survival. The biological function of E2F2 was annotated by Gene set enrichment analysis (GSEA).Results: The expression of E2F2 was increased in HCC samples. The expression of elevated E2F2 in HCC samples was prominently correlated with histologic grade (OR =2.62 for G3-4 vs. G1-2, p=1.80E-05), clinical stage (OR =1.74 for III-IV vs. I-II, p=0.03), T (OR =1.64 for T3-4 vs.T1-2, p=0.04), tumor status (OR =1.88 for with tumor vs. tumor free, p= 3.79E-03), plasma alpha fetoprotein (AFP) value (OR =3.18 for AFP≥400 vs AFP＜20, p= 2.16E-04; OR=2.50 for 20≤AFP＜400 vs AFP＜20, p=2.56E-03). Increased E2F2 had an unfavorable OS (p=7.468e−05), PFI (p=3.183e−05), DFI (p=0.001), DSS (p=4.172e−05). Elevated E2F2 was independently bound up with OS (p =0.004 , hazard ratio [HR]= 2.4 (95% CI [1.3-4.2])), DFI (P =0.029, hazard ratio [HR] = 2.0 (95% CI [1.1-3.7])) and PFI (P =0.005, hazard ratio [HR] = 2.2 (95% CI [1.3-3.9])) . GSEA disclosed that cell circle, RNA degradation, pyrimidine metabolism, base excision repair, aminoacyl tRNA biosynthesis, DNA replication, p53 signaling pathway, nucleotide excision repair, ubiquitin mediated proteolysis, citrate cycle TCA cycle were notably enriched in E2F2 high expression phenotype.Conclusions: Elevated E2F2 can be a promising independent prognostic biomarker and therapeutic target for HCC. Additionally, cell cycle, pyrimidine metabolism, DNA replication, p53 signaling pathway, ubiquitin mediated proteolysis, the citrate cycle TCA cycle may be the key pathway by which E2F2 participate in the initial and progression of HCC.

Published: August 2020

Abstract
Background: To evaluate the influence of automated visual field (VF) testing on intraocular pressure (IOP) in patients with ocular hypertension (OHT) or glaucoma.Methods: We conducted a prospective observational study in the glaucoma department at Quinze-Vingts National Ophthalmology Hospital in Paris. Ninety-five right eyes of 95 patients followed for glaucoma or OHT were included. IOP was measured three times using a Nidek NT-510 non-contact tonometer within a maximum of 5 minutes before and after VF testing. Sub analyses using logistic regression analysis were performed to evaluate the impact of gender, age, central corneal thickness (CCT), mean deviation (MD) of the VF, VF test duration and filtration surgery on IOP fluctuations.Results: There was no significant change in IOP after VF testing, with IOP’s 15.14 ± 4.00 mmHg before and 14.98 ± 3.33 mmHg after the VF (P = 0.4). The average change in IOP was 0.15 ± 1.82 mmHg. Using multivariate analysis, no effect of the VF test on IOP was found (global model fit R²=0.12), whether based on duration of the VF test (P=0.18) or the MD (P=0.7) after adjustment for age, gender, CCT and history of glaucoma surgery. Similarly, there was no significant difference within different types of glaucoma, including open-angle glaucoma (P=0.36), chronic angle closure glaucoma (P=0.85) and OHT (P=0.42). The subgroup of patients with an IOP elevation ≥ 2mmHg had a significantly higher VF test duration (P=0.002).Conclusion: VF testing does not influence IOP as measured with a non-contact tonometer.
