ABSTRACT
Objective: To investigate the frequency of suicidal ideation and its correlation with other clinical variables in patients with pulmonary arterial hypertension.
Methods: Fifty patients with pulmonary arterial hypertension who presented to the cardiology department between 2018 and 2019 and 50 healthy controls were included in the study. A sociodemographic and clinical data form was completed by both the patients and controls, and the Beck Depression Inventory (BDI), Beck Hopelessness Scale (BHS), Rosenberg Self-Esteem Scale (RSE), and Suicide Probability Scale (SPS) were administered. SPSS version 22 software was used in the statistical analysis.
Results: The mean ± SD systolic pulmonary pressure of the patients was 47.48 ± 18.86 and the pulmonary artery pressure was 33.32 ± 19.69. BHS, BDI, and SPS total scores were statistically significantly higher in the patient group compared to the control group (P < .001, P = .001, P = .026, respectively). RSE scores were also higher in the patient group compared to the control group (P = .017).
Conclusions: It is important to identify pulmonary arterial hypertension patients with intense feelings of hopelessness and depressive symptoms and to provide psychiatric treatment and psychotherapeutic interventions to improve their self-esteem.

ABSTRACT
OBJECTIVES: Some dental schools depend on the students’ academic performance for admission purposes. This research aimed at investigating the correlations between dental students’ performance in specific academic courses and their preclinical and clinical counterparts, and the correlations between students’ performance in the pre-clinical practical courses and the clinical courses.
METHODS: Academic and practical preclinical and clinical grades were retrieved for 811 students who graduated from the School of Dentistry, the University of Jordan between 2016 and 2018. Ten courses (five academic and five practical) were selected. Pearson’s rho test was used to calculate the correlations between the courses.
RESULTS: Statistically significant weak to moderate positive correlations were found between each academic course and its preclinical or clinical counterparts and between preclinical and clinical courses. A statistically significant positive moderate correlation (P<0.001) was found between students’ performance in fourth and fifth year restorative clinics.
CONCLUSION: The results of this study suggest that the academic performance could partially predict the practical performance in both the pre-clinical and clinical courses and that the clinical performance could partially be predicted from the pre-clinical practical performance. Moreover, students who can successfully perform the required clinical procedures in fourth year will successfully perform the required clinical procedures in fifth year. However, other confounding factors should be taken into consideration such as manual dexterity and artistic skills even though their intellectual abilities are average.

ABSTRACT
Type 1 diabetes (T1DM) ethiopathogenesis is still being studied, since the role of environmental factors , especially viruses, is not yet clear. This study was conducted on 31 paediatric patients with T1DM at onset. We analysed: Coxsackieviruses A (CoxA), Coxsackieviruses B (CoxB), Echoviruses (Echo); Influenzavirus A and B (IV-A and IV-B); Adenovirus (AdV); Parainfluenza viruses 1-2 and 3 ( PiV 1-2-3); Cytomegalovirus (CMV) and Respiratory Syncytial Virus (RSV). Enteroviruses, especially CoxB and Echo, are most represented. Unexpectedly, Parainfluenza viruses were detected in seasonal subgroups, with peaks in autumn and spring, and spread homogeneously in different age groups.

ABSTRACT
The prognosis of patients with multiple myeloma (MM) with extramedullary disease (EMD) remains poor. A high overall response rate (ORR) has been reported following anti-B-cell maturation antigen (BCMA) chimeric antigen receptor (CAR)-T cell therapy in relapsed/ refractory (R/R) patients with MM; however, data on patients with EMD remain limited. Herein, we compared and analyzed the efficacy and long-term follow-up of anti-BCMA CAR-T cell therapy in R/R MM patients with extramedullary-extraosseous (EM-E), extramedullary-bone related (EM-B), and without extramedullary disease. No difference in the ORR was observed between the three groups. The long-term efficacy of anti-BCMA CAR-T cell therapy in the EM-E group was worse than that in patients without EMD and with EM-B. In the EM-E group, disease progression was the reappearance of extramedullary lesions without an increase in the MM cell percentage or M protein level. Although no difference in the proportion of CAR-T cells was detected among the three groups, the EM-E group might exhibit a relatively high grade of cytokine release syndrome following anti-BCMA CAR-T therapy. Interleukin-6 levels in the without EMD group were lower than those in the EM-E and EM-B groups. However, given the small number of cases in the three groups, statistical analysis was not performed.

ABSTRACT
OBJECTIVES: Obesity may increase the risk of vascular complications in transfemoral (TF) transcatheter aortic valve replacement (TAVR) procedures. The transcarotid (TC) approach has recently emerged as an alternative access in TAVR. We sought to compare vascular complications and early clinical outcomes in obese patients undergoing TAVR either by TF or TC vascular access.
METHODS: Multicentre registry including obese patients undergoing TF- or TC-TAVR in 15 tertiary centres. All patients received newer-generation transcatheter heart valves. For patients exhibiting unfavourable ileo-femoral anatomic characteristics, the TC approach was favoured in 3 centres with experience with it. A propensity score analysis was performed for overcoming unbalanced baseline covariates. The primary end point was the occurrence of in-hospital vascular complications (Valve Academic Research Consortium-2 criteria).
RESULTS: A total of 539 patients were included, 454 (84.2%) and 85 (15.8%) had a TF and TC access, respectively. In the propensity-adjusted cohort (TF: 442 patients; TC: 85 patients), both baseline and procedural valve-related characteristics were well-balanced between groups. A significant decrease in vascular complications was observed in the TC group (3.5% vs 12% in the TF group, odds ratio: 0.26, 95% CI: 0.07-0.95, P = 0.037). There were no statistically significant differences between groups regarding in-hospital mortality (TC: 2.8%, TF: 1.5%), stroke (TC: 1.2%, TF: 0.4%) and life-threatening/major bleeding events (TC: 2.8%, TF: 3.8%).
CONCLUSIONS: In patients with obesity undergoing TAVR with newer-generation devices, the TC access was associated with a lower rate of vascular complications. Larger randomized studies are warranted to further assess the better approach for TAVR in obese patients.

ABSTRACT
BACKGROUND: The aim of this study is to evaluate upper airway changes three-dimensionally following rapid maxillary expansion (RME) and compare the changes with matched controls.
MATERIALS AND METHODS: Seventeen patients (mean age 12.6 ± 1.8 years) with maxillary transverse deficiency were treated with RME. Using the propensity score matching method, 17 patients (mean age 12.3 ± 1.5 years) were selected from a non-RME control group of 33. Case-control matching was performed based on 5 covariates: age, gender, CBCT scan interval, sagittal skeletal pattern, and tongue posture. Airway volumes of nasopharynx and oropharynx and minimum cross-sectional areas (MCA) of oropharynx were measured and compared between the case and control groups in CBCT scan images.
RESULTS: In the case group, significant increases from before to after RME were found in all measurements except MCA of the retroglossal segment of oropharynx. Before treatment, there were no significant differences between case group and control group. While comparing the case group with the control group after treatment showed overall greater increases in the case group. In particular, MCA of retropalatal segment showed statistically significant differences.
CONCLUSION: The results of this study indicate that RME causes an increase in upper airway dimensions.

ABSTRACT
BACKGROUND AND AIMS: Colorectal adenomas are precursor lesions for colorectal cancer (CRC), a major cause of cancer-related death. Despite all molecular insights, there are still unknown variables in the development of CRC as well as uncertainties regarding adenoma recurrence after resection. We aimed to characterize the expression of docking protein 1 (DOK1) and myotubularin-related protein 7 (MTMR7), which share inhibiting functions on EGFR-RAS-signalling, a major oncogenic driver in CRC, and their association with clinical variables and adenoma recurrence.
METHODS: This observational study is based on clinical data obtained from patients who underwent routine endoscopy and consecutive follow-up examinations. Immunohistochemistry was conducted both in dysplastic tissue and adjacent non-dysplastic mucosa followed by microscopical assessment. Recurrence was differentiated between local, segmental and distant relapse.
RESULTS: A total of 56 patients (23 females) gathering 96 adenomas/polyps were included. 36 patients experienced a metachronous lesion, 23 patients had simultaneous lesions in their index endoscopy. Female patients showed lower levels of MTMR7 in adenomas (p=0.0318). Adenomas of young patients showed lower DOK1 than those of older patients (p=0.0469). Big adenomas showed a higher expression of DOK1 than small lesions (p=0.0044). In serrated lesions, DOK1 was reduced (p=0.0026) and correlated with the quantity of lesions (p < 0.001). MTMR7 was significantly reduced in distant (p=0.05) and local segmental recurrence (p=0.0362), while DOK1 showed higher expression in recurrence (p=0.0291).
CONCLUSIONS: We found ambivalent results regarding the role of the markers as potential tumor suppressors, implying a context-dependent function of these molecules which might change in the course of time. DOK1 may play an inhibiting role in the serrated pathway. Remarkably, molecular markers have the potential to predict recurrence, since a combined expression analysis of high DOK1 and low MTMR7 correlated with the likelihood of segmental adenoma recurrence.

ABSTRACT
BACKGROUND: Local relapse of oral squamous cell carcinoma in non-involved mucosal surgical margins indicated possibility of field alteration in the margins, which could be predicted with certain biomarkers. The objectives were to evaluate the expression of Ki-67, Cornulin and ISG15 in non-involved mucosal surgical margins and the association of clinicopathological prognosticators with local relapse in oral squamous cell carcinoma.
METHODS: Surgical margins from the study (relapse) group (n = 23), control (non-relapse) group (n = 32) and normal oral mucosa (n = 5) were immunohistochemically stained using Ki-67, Cornulin and ISG15 antibodies. Association between expression of markers and clinicopathological prognosticators with local relapse in oral squamous cell carcinoma was analyzed statistically.
RESULTS: The study group surgical margins demonstrated significantly decreased Cornulin expression (p = 0.032). Low Cornulin expression was significantly associated with local relapse (p = 0.004) and non-tongue primary tumor (p = 0.013). Although not significantly associated with local relapse, expression of Ki-67 was significantly reduced in female patients (p = 0.041). Age above 57.5 years, Chinese & Indian ethnicity, alcohol consumption, epithelial dysplasia in surgical margins, and type III and IV patterns of invasion of tumor were also significantly related to local relapse. Regression analysis showed low expression of Cornulin (p = 0.018), and increased patient’s age (p = 0.008) were predictors of local relapse in oral squamous cell carcinoma, with 34-fold risk and 18-fold risk, respectively. Expression of Ki-67 and ISG15 did not show significant association with local relapse in oral squamous cell carcinoma.
CONCLUSION: Low expression of Cornulin is an independent predictor of relapse in oral squamous cell carcinoma.

ABSTRACT
Vonoprazan, a potassium-competitive acid blocker, is expected to be superior to proton pump inhibitors (PPIs) in preventing post-endoscopic submucosal dissection (ESD)-induced gastric bleeding. However, the results of randomized controlled trials (RCTs) and observational studies on the efficacy of vonoprazan have been inconsistent. This study aimed to evaluate the effectiveness of vonoprazan in antithrombotic drug users, a population that has been excluded from RCTs. Treatment effects were assessed using cross-design synthesis, which can be adjusted for differences in study design and patient characteristics. We used data from an RCT in Japan (70 patients in the vonoprazan group and 69 in the PPI group) and an observational study (408 patients in the vonoprazan group and 870 in the PPI group). After matching, among the antithrombotic drug users in the observational study, post-ESD bleeding was noted in 8 out of 86 patients in the vonoprazan group and 18 out of 86 patients in the PPI group. After pooling the data from the RCT and observational study, the risk difference for antithrombotic drug users was -14.6% (95% CI: -22.0 to -7.2). CDS analysis suggested that vonoprazan is more effective than PPIs in preventing post-ESD bleeding among patients administered antithrombotic medications.
