Abstract
Background: Vitamin D receptor (VDR) is involved in multiple immune-mediated disorders including oral lichen planus (OLP). This study investigated the association between VDR gene polymorphisms and the risk of OLP. Methods: In total, 177 OLP patients and 207 healthy participants were recruited from the Affiliated Hospital of Stomatology, Nanjing Medical University. Eight single nucleotide polymorphisms (SNPs: rs731236, rs739837, rs757343, rs2107301, rs2239185, rs7975232, rs11574129 and rs11568820) in the VDR gene were selected and genotyped. Results: The results showed that OLP risk was increased in subjects with the rs2239185 TT genotype (Recessive model: adjusted OR = 2.68, 95% CI = 1.28-5.62, P = 0.009) and rs7975232 CC genotype (Recessive model: adjusted OR = 2.25, 95% CI = 1.10-4.58, P = 0.026). Moreover, rs2239185 and rs7975232 (P < 0.01) showed significant cumulative effects on OLP risk...Haplotype analysis showed that the CC haplotype (rs2239185-rs7975232) was associated with an increased risk of OLP (OR = 3.11, 95% CI = 1.42-6.83, P = 0.005), compared with the AC haplotype. Conclusion: the rs2239185 and rs7975232 variants of VDR may influence OLP susceptibility, and VDR gene polymorphisms may be candidate susceptibility regions for OLP in a Chinese Han population.

Abstract
Background: Research on the factors associated with dialysis withdrawal in dialysis patients has been limited. Authors have used different definitions for dialysis withdrawal, resulting in inconsistent findings. The objective of this study was to determine the factors associated with dialysis withdrawal in dialysis patients.Methods: This retrospective study extracted patient information from the electronic renal patient management systems at the Grand River Hospital. A total of 723 patients who initiated renal dialysis therapy (> 30 days of duration) in the renal dialysis program at Grand River Hospital (GRH), Ontario, during the period from 1st January 2012 to 30th September 2017 were consecutively included in the study. Logistic regression was used to determine the factors: age, sex, modality, comorbidities, the cause of primary renal disease, dialysis modality, and duration of dialysis-associated with dialysis withdrawal. Dialysis withdrawal was defined as “patient declined further treatment or voluntary withdrawal from the dialysis program”.Results: The mean age of the sample was 64.86 ± 14.89 years, and 62.8% (n = 454) were males. The prevalence of dialysis withdrawal was 9.41% (n = 68). The logistic regression model showed that factors associated with dialysis withdrawal were as follows: cardiac disease [Adjusted Odds Ratio (AOR)= 1.921; 95% CI= 1.126–3.278], hypertension [AOR = 5.711; 95% CI = 1.322- 24.676], dementia [AOR = 3.042; 95% CI = 1.325–6.983], age [AOR = 1.035; 95% CI = 1.012– 1.058] and duration of dialysis [AOR = 0.999; 95% CI = 0.999–1.00].Conclusion: In this study we show that age, cardiac disease, hypertension, and dementia are significant predictors related to dialysis withdrawal. The findings might help in identifying patients who are more likely to withdraw from dialysis at the start of dialysis. Future researchers and nephrologists should design and conduct intervention studies focusing on strategies controlling the severity of comorbidities (cardiac disease and hypertension), regular assessment and monitoring of the progression of dementia, and other dialysis program changes to help patients make more informed decisions regarding dialysis withdrawal.

Published: December 2019

Abstract
Background: Competitive endogenous RNAs (ceRNAs) have revealed a new mechanism of interaction between RNAs. However, an understanding of the ceRNA regulatory network in Wilms tumour (WT) remains limited.Methods: The expression profiles of mRNAs, miRNAs and lncRNAs in Wilms tumour samples and normal samples were obtained from the Therapeutically Applicable Research to Generate Effective Treatment (TARGET) database. The EdgeR package was employed to identify differentially expressed lncRNAs, miRNAs and mRNAs. Functional enrichment analyses via the ClusterProfile R package were performed, and the lncRNA–miRNA–mRNA interaction ceRNA network was established in Cytoscape. Subsequently, the correlation between the ceRNA network and overall survival was analysed.Results: A total of 2,037 lncRNAs, 154 miRNAs and 3,609 mRNAs were identified as differentially expressed RNAs in Wilms tumour. Of those, 205 lncRNAs, 26 miRNAs and 143 mRNAs were included in the ceRNA regulatory network. The results of Gene Ontology (GO) analysis revealed that the differentially expressed genes (DEGs) were mainly enriched in terms related to response to mechanical stimuli, transcription factor complexes, and transcription factor activity (related to RNA polymerase II proximal promoter sequence-specific DNA binding). The results of the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis showed that the DEGs were mainly enriched in pathways related to the cell cycle. The survival analysis results showed that 16 out of the 205 lncRNAs, 1 out of 26 miRNAs and 5 out of 143 mRNAs were associated with overall survival in Wilms tumour patients (P < 0.05).Conclusions: CeRNA networks play an important role in Wilms tumour. This finding might provide effective, novel insights for further understanding the mechanisms underlying Wilms tumour.

Abstract
Background: Human immunological memory is a hallmark of the adaptive immune system and plays an important role in the development of effective immune responses against tumors. In the present study, we aimed to determine the frequencies of CD8+ memory T cell subsets including stem memory T cells (TSCM) in tumor-draining lymph nodes of patients with breast cancer (BC).
Methods: Mononuclear cells were obtained from axillary lymph nodes of 52 untreated patients with BC and stained for CD8, CCR7, CD45RO, CD95 markers to detect different subtypes of memory cells in the CD8+ lymphocyte population. Data were acquired on four-color flow cytometry and analyzed with CellQuest Pro software.
Results: We observed that 47.65±2.66 of CD8+ lymphocytes expressed the CD45RO, a marker for memory T cells. Statistical analysis showed that the total frequency of central memory T cells (TCM) and their subset with low CD45RO expression was significantly higher in tumor-involved nodes compared to tumor-free ones (P=0.024 and P=0.017, respectively). The level of CD95 expression (based on mean fluorescence intensity) on the surface of TCM, their CD45ROhi and CD45ROlow subsets, and TSCM was higher in patients with stage II compared to those in stage I (P<0.05). In addition, the percentage of naive CD8+ T cells was significantly higher in tumor-involved lymph nodes compared to tumor-free ones (P=0.025).
Conclusions: Our data collectively indicate no significant differences in the frequencies of CD8+ lymphocytes or their memory subsets in tumor-draining lymph nodes of patients with BC. However, the frequencies of CD45low TCM along with naive CD8+ lymphocytes were higher in tumor-involved nodes, which suggests that after long-term exposure to the antigen, and despite the immune reaction in order to provide a pool of effective memory cells, memory cell differentiation is blocked in early-stage (CD45ROlow) due to tumor-derived suppressive factors. Identifying the molecular and cellular mechanisms behind this suppression can provide invaluable tools for adoptive T cell therapies in cancer.

Abstract
Background:
A previous phase I/II C-TASK FORCE study of trifluridine/tipiracil plus bevacizumab for patients with heavily pretreated metastatic colorectal cancer (mCRC) showed promising activity with an acceptable toxicity profile. This retrospective study aimed to investigate the safety and efficacy of trifluridine/tipiracil plus bevacizumab compared with trifluridine/tipiracil monotherapy in patients with heavily pretreated mCRC in clinical settings.
Methods:
Records of patients with mCRC refractory to standard therapies who initiated trifluridine/tipiracil plus bevacizumab from January 2016 to March 2018 or trifluridine/tipiracil monotherapy from June 2014 to December 2015 were retrospectively reviewed at our institution.
Results:
Totally, 60 patients received trifluridine/tipiracil plus bevacizumab and 66 received trifluridine/tipiracil monotherapy. All patients had previously received standard chemotherapy. Median progression-free survival (PFS) was 3.7 months [95% confidence interval (CI), 2.3−5.1] in the trifluridine/tipiracil plus bevacizumab group and 2.2 months (95% CI, 1.8−2.6) in the trifluridine/tipiracil monotherapy group [hazards ratio (HR) 0.69; 95% CI 0.48−0.99]. PFS rate at 16 weeks was 46.6% for the trifluridine/tipiracil plus bevacizumab group and 33.9% for the trifluridine/tipiracil monotherapy group. Although a relatively higher incidence of grade ≥3 neutropenia was observed in the trifluridine/tipiracil plus bevacizumab group than that in the other group (50.0% vs. 40.9%, p = 0.371), the incidence of febrile neutropenia was not high (3.3% vs. 7.8%, p = 0.444).
Conclusions:
In real-world settings, trifluridine/tipiracil plus bevacizumab prolonged PFS and helped achieve higher 16-week PFS rate compared with trifluridine/tipiracil monotherapy in patients with heavily pretreated mCRC with manageable toxicities.

Abstract
Background : Recent genome-wide association studies (GWASs) have suggested several susceptibility loci of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) by statistical analysis at individual single-nucleotide polymorphisms (SNPs). However, these loci only explain a small fraction of HBV-related HCC heritability. In the present study, we aimed to identify additional susceptibility loci of HBV-related HCC using advanced knowledge-based analysis.Methods: We performed knowledge-based analysis (including gene- and gene-set-based association tests) on variant-level association p-values from two existing GWASs of HBV-related HCC. Five different types of gene-sets were collected for the association analysis. A number of SNPs within the gene prioritized by the knowledge-based association tests were selected to replicate genetic associations in an independent sample of 965 cases and 923 controls.Results: The gene-based association analysis detected four genes significantly or suggestively associated with HBV-related HCC risk: SLC39A8, GOLGA8M, SMIM31, and WHAMMP2. The gene-set-based association analysis prioritized two promising gene set for HCC, cell cycle G1/S transition and NOTCH1 intracellular domain regulates transcription. Within the gene sets, three promising candidate genes (CDC45, NCOR1 and KAT2A) were further prioritized for HCC. Among genes of liver-specific expression, multiple genes previously implicated in HCC were also highlighted. However, probably due to small sample size, none of the genes prioritized by the knowledge-based association analyses are successfully replicated in the independent sample. Conclusions: This comprehensive knowledge-based association mining study suggested several promising genes and gene-sets associated with HBV-related HCC risk. More experiments or larger samples are needed to validate their contribution to the pathogenic mechanism of HCC.

Published: December 2019

Abstract
Introduction: The License, Master, and Doctorate (LMD) reform which structured high studies in three cycles was instituted since the Bologna declaration on 1999. To be conformed with international standards, the LMD system was instituted in university of Lomé in 2009 to foster flexible pathways between medical and paramedical training. The purpose of this study was to evaluate the strengths and weaknesses of the LMD reform since its introduction in medical school of Lomé.Method: It was an opinion survey conducted in 4 months in University of Lomé among the medical school’s teachers about strengths and weaknesses of LMD reform since its application. The strengths were defined as all facilities brought by LMD reform in organization of courses and practices, evaluations, new Information and Communication Technologies (ICTs) (internet, video projector, courses on line). The LMD weaknesses were defined as any problem generated by the LMD. Results: Seventy-six out of on 113 resident teachers of the medical school of Lomé had completed the questionnaires (67.2%). Mostly teachers (74) took that the introduction of LMD reform will make Lomé medical school on international standards. The availability of the video projectors was noted by 90.8% of the teachers and used for teaching in (82.9%). No course dispensed in medical school was online. The main strengths of LMD were: best student’s evaluation (33.3), the organization of training in units with credit (28.6), using new ICTs (23.8%). Many weaknesses of LMD reform were noted by teachers: the plethoric number of students (36.2%), the absence of intermediate diploma and pathways between studies (29.3). The Insufficiency of personnel resources and material was also mentioned. Conclusion: This study highlights that LMD reform needs adaptation to local realities and improvement to ensure that students will get good training in compliance with international standards.

Published: December 2019

Abstract
Background
Street child is any child whose age is less than 18 years for whom the street has become his or her habitual abode and/or source of livelihood, is inadequately protected, supervised or directed by responsible adults. In Ethiopia the health problems of street children are given poor attention in research. This problem is pronounced when it comes to intestinal parasitic infections . The aim of this study was to assess the prevalence of intestinal parasitic infections and associated factors among street children in Jimma town in the year 2019.
Methods and Materials: Community based cross sectional study was employed. Complete enumeration was used to include 312 street children. Pretested questionnaire was used to collect the data. Data was entered to Epidata version 3.1 and exported to SPSS version 20. Stool samples were examined by wet mount and formalin ether concentration techniques. Bivariable and multivariable logistic regression was used to identify factors associated with intestinal parasitic infection. Significance of association was decided by using the 95% confidence interval of AOR and P-value of ≤ 0.05 in the multivariable model.
Result: A total of 312 children of the street were involved in the study making the response rate 96.2%. The prevalence of intestinal parasitic infection was 66.7%. Untrimmed finger nails AOR=2.03;95%CI (1.02-4.06), eating street food AOR=2.24;95% CI (1.04-5.02), practice of swimming in unprotected water bodies AOR=2.5; 95% CI (1.24-5.04), not wearing shoes at the time of data collection AOR= 3.8;95% CI (1.8-8.2) and lacking knowledge of way of transmission of intestinal parasites AOR= 2.5; 95% CI (1.25- 5.0) were significantly associated with parasitic infections.
Conclusion and Recommendations: The prevalence of intestinal parasitic infections among street children in the study area was high and require integrated interventions to avert the problem. Factors like untrimmed finger nails, swimming practice, eating street foods, shoe wearing and lacking knowledge of ways of transmission of intestinal parasitic infections are associated with infection status. Measures has to be taken to curb the problem by including them in mass drug administration and targeted health education towards identified factors.

Published: December 2019

Abstract
Abstract Objective: To investigate the effects of protective lung ventilation on regional cerebral oxygen saturation during dura opening, that is from Ta (after dura opening) to Tb (before dura closing), in patients undergoing intracranial tumor surgery. Methods: This is a randomized, controlled trial which will be carried out at the second affiliated hospital of Soochow University. Fifty-four patients undergoing intracranial tumor surgery will be randomly allocated to the control group (C group) or the protective lung ventilation group (P group). In the C group, tidal volume (VT) will be set at 8 ml/kg of predicted body weight, but positive end-expiratory pressure (PEEP) and recruitment maneuvers will not be used. In the P group, VT will be set at 6 ml/kg of predicted body weight combined with individualized PEEP during dura opening, while in other periods of general anesthesia, VT will be set at 8 ml/kg of predicted body weight. Regional cerebral oxygen saturation (rSO2), partial pressure of oxygen (PaO2) and carbon dioxide (PaCO2), oxygenation index (OI), lactic acid level (Lac) in arterial blood, and mean arterial pressure (MAP) will be compared before anesthesia (T0), before dura opening (T1), after dura closing (T2) and 24 h after surgery (T3). Lung ultrasound scores (LUS) will be performed at T0 and T3. The degree of brain relaxation at T1 and T2 will be evaluated by the surgeon using the brain relaxation scale. Amount of vasoactive drugs used and blood loss will be recorded during surgery. The duration of operation and reoperation rate will be recorded. Discussion: This study aims to determine whether protective lung ventilation during dura opening can improve regional cerebral oxygen saturation and the state of pulmonary ventilation in patients undergoing intracranial tumor surgery, and to investigate whether this strategy does not affect the degree of brain tissue swelling and the reoperation rate after operation. If our results are positive, this study will show that protective lung ventilation during dura opening can be used effectively and safely in neurosurgical patients undergoing craniotomy for tumor resection.

Abstract
Background Biopsy is considered the gold-standard technique for prostate cancer diagnosis and is recommended in patients with a high clinical indication of prostate cancer. In this study, we aimed to determine the diagnostic efficacy of a novel positron emission tomography (PET)/computed tomography (CT)-guided percutaneous trans-pararectal space-based approach to targeted prostate biopsy.Methods PET/CT-guided percutaneous trans-pararectal space prostate biopsies were performed in 14 consecutive patients with indications of prostate cancer. Whole-body 18F-FDG PET/CT indicated the presence of 18F-fluorodeoxyglucose (FDG)-avid focal prostate lesions. Two tissue specimens were obtained from each patient. The final diagnoses were established based on the results of a histopathological analysis and clinical follow-up, and these findings were used to verify the diagnostic accuracy of 18F-FDG PET/CT for prostate cancer.Results The diagnostic accuracy of 18F-FDG PET/CT for prostate cancer was 81.8%. Further analyses of the two biopsied samples per patient led to confirmed histopathological and immunohistochemical diagnoses of prostate cancer in all 14 patients. Consequently, the success rate of PET/CT-guided percutaneous trans-pararectal space prostate-targeted biopsy for the diagnosis of prostate cancer was 100.0% (14/14). Regarding safety, the average duration of biopsy was 20 min, and no serious complications occurred.Conclusions PET/CT-guided percutaneous trans-pararectal space prostate biopsy may yield a new approach to targeted prostate biopsy for the diagnosis of prostate cancer. Moreover, this biopsy procedure can be performed safely without complications, and is more cost-effective than conventional trans-rectal and trans-perineal prostate biopsy methods.
