Abstract
Background Inflammatory bowel disease (IBD) is a chronic inflammatory disease that associated with complicated interaction between immune, gut microbiota and environmental factors in a genetically vulnerable host. Dysbiosis is often seen in patients with IBD. Our aim is to investigate the fecal microbiota in patients with IBD and compared to healthy controls in Taiwan. Methods In this cross-sectional study, we investigated fecal microbiota in 20 patients with IBD and 48 healthy controls. Fecal samples from both IBD patients and controls were analyzed by next-generation sequencing method and relevant software. Results The IBD group showed lower bacterial richness and diversity compared to the control group. The principal coordinate analysis also revealed significant structural difference between the IBD group and the control group. These findings were consistent whether the analysis was based on operational taxonomic unit or amplicon sequence variant. However, no significant difference was found when comparing the composition of fecal microbiota between ulcerative colitis (UC) and Crohn’s disease (CD). Further analysis showed that Lactobacillus, Enterococcus, Bifidobacterium and Veillonella were dominant in the IBD group, while Faecalibacterium and Subdoligranulum were dominant in the control group at genus level. When comparing UC, CD and control group, Lactobacillus, Bifidobacterium and Enterococcus were identified as dominant genera in the UC group. Fusobacterium and Escherichia_Shigella were dominant in the CD group. Faecalibacterium and Subdoligranulum were dominant in the control group. Conclusions Compared to the healthy control, the IBD group showed dysbiosis with a significant decreased in both richness and diversity of gut microbiota.

Abstract
Background: COVID-19 continuously threated public health heavily. Present study aimed to investigate the lymphocyte subset alterations with disease severity, imaging manifestation, and delayed hospitalization in COVID-19 patients.Methods: Lymphocyte subsets was classified using flow cytometry with peripheral blood collected from 106 patients.Results: Multivariate logistic regression showed that chest tightness, lymphocyte count, and γ-glutamyl transpeptidase were the independent predictors for severe COVID-19. The T cell, CD4+ T cell and B cell counts in severe patients were significantly lower than that in mild patients (p = 0.004, 0.003 and 0.046, respectively). Only the T cell count was gradually decreased with the increase of infiltrated quadrants of lesions in computed tomography (CT) (p = 0.043). The T cell, CD4+ T cell, and CD8+ T cell counts were gradually decreased with the increase of infiltrated area of the maximum lesion in CT (p = 0.002, 0.003, 0.028; respectively). The T cell count, as well as CD4+ T cell, CD8+ T cell, and NK cell counts were gradually decreased with the increased delayed hospitalization (p = 0.003, 0.002, 0.013, and 0.012; respectively). The proportion of T cell was gradually decreased but B cell was gradually increased with the increased delayed hospitalization (p = 0.031 and 0.003, respectively).Conclusion: T cell and CD4+ T cell counts negatively correlated with disease severity, CT manifestation and delayed hospitalization. CD4+ T cell was mainstay of immunity response in COVID-19 patients.

Abstract
BackgroundA student’s motivation is a key factor in their success in undertaking an education endeavour. However, how this relates to involvement in research by medical students is unclear.MethodsAn electronic questionnaire was sent to all medical students at our institution. To ascertain students’ motivation to undertake research, they were asked an open-ended question to describe the single major factor that would encourage them to get involved in research as a medical student. A framework of self-determination theory was used to deductively code the responses as intrinsic motivation (‘IM’; e.g., interest/passion) or extrinsic motivation (‘EM’; e.g. improving CV). The two groups were then contrasted in relation to their research engagement.ResultsA total of 348 students were included in the survey, of whom 204 were coded as IM responses, and 144 were coded as EM responses. Students who engaged in extra-curricular research activities were more likely to report an underlying EM (48% vs. 36%, p = 0.03). They were also older (23.7 ± 3.5 vs. 21.9 ± 3.7, p = 0.005), and more likely to have completed a prior research degree (15% vs. 3%, p = 0.01).ConclusionIn this study, EM was a bigger influencer on research involvement by medical students than IM. Future studies should explore promoters of IM, and include longitudinal data in order to assess whether EM students continue to be involved in research long-term.

Abstract
BackgroundHypersplenism is a common consequence of liver cirrhosis and a risk factor of hepatocellular carcinoma (HCC) development. The objective of the current study was to identify whether splenectomy for treatment of hypersplenism has any impact on risk of HCC. ­­MethodsPatients who underwent splenectomy for hypersplenism secondary to liver cirrhosis and portal hypertension between 2008 and 2012 were included from seven University Hospitals in China, whereas patients receiving medication treatments for liver cirrhosis and portal hypertension (non-splenectomy) at this time period were also included as control. ResultsA total of 871 patients with liver cirrhosis and hypertension were included synchronously from 7 tertiary hospitals. Among them, 407 patients had a history of splenectomy for hypersplenism, whereas 464 patients who received medical treatment but not splenectomy (non-splenectomy group). The cumulative incidence of HCC development at 1, 3, 5 and 7 years were 1%, 6%, 11% and 16% in splenectomy group, and 2%, 10%, 17% and 24% in non-splenectomy group in the unadjusted cohort (Breslow test = 7.7, p=0.005). Consistently, in the matched cohort, the cumulative rates of HCC diagnosis at 1, 3, 5 and 7 years were 1%, 6%, 7% and 15% in splenectomy group, and 1%, 6%, 15% and 23% in non-splenectomy group (Breslow test = 4.9, p=0.028). On multivariable analysis, splenectomy was independently associated with decreased risk of HCC development (HR 0.55, 95% CI, 0.32-0.95, p=0.031). ConclusionSplenectomy for treatment of hypersplenism may decrease the risk of HCC development.

Abstract
In this review we describe the relation between nasal eosinophilia and rheumatoid arthritis (RA). Moreover we was performed a literature revision that valued the relation between eosinophilia in respiratory system with arthritis. We have examined, through nasal cytology, 7 patients (5 men and 2 women) aged between 7 and 60 years old, with a middle age of 38,5 years; this patients are affected by RA, members of UO of Diagnostic ORL and nasal cytology of the AIAS (Italian Association of Disadvantages assistance) of Afragola.Between them we put in evidence only a case of youth RA. All patients was not allergic and affected by recurrent rhinitis in maintenance therapy and not related with pollen calendar. The withdrawal documented the presence of rare eosinophils in nasal mucosa. This evidence could induce us to use this practice not only as follow up of patients but also as means of early diagnosis.

Abstract
The adhesion of coatings on a given substrate has fundamental importance on the functionality of a coating/substrate system. The current paper presents the adhesion strength results of FeCr and CoCr-based deposits produced by electric arc thermal spray process on carbon steel, with an intermediate layer of 95Ni5Al. Three chemical compositions were tested for coating deposition and was characterized using plate and tube specimens made of carbon steel UNS G10200 to result in a screening of performance. Microstructural evaluation by optical microscopy (OM), scanning electron microscopy (SEM) and X-ray diffraction (XRD) were performed. Coating strength was measured using standard pull-off test method. The corrosion resistance was analyzed with salt spray exposure, electrochemical polarization and impedance spectroscopy (EIS) tests. The adhesion strength of FeCr and CoCr alloy coatings shows an overall average tensile strength of 27.2 MPa. All sealed conditions presented low corrosion and the samples with epoxy sealant exhibited a high resistance against corrosion. The X-ray diffraction results have revealed the presence of alpha and gamma FeCr alloys and chromite as deposited phases after the coating process.

Abstract
Background: We investigate L1CAM expression in ER positive/HER2 negative breast carcinomas. The finding of a potential correlation between high L1CAM expression and recurrent/metastatic disease in luminal A and B breast carcinomas may be helpful for risk stratification and open opportunities for targeted therapies.Methods: 304 cases comprising 152 cases of ER positive, PR positive/negative and HER2 negative recurrent/metastatic breast carcinomas and 152 non-recurrent controls were included. ER, PR, HER-2, Ki-67 status, Nottingham grade, tumor size, tumor stage, number of foci, lymph node status, lymphovascular invasion, phenotype, laterality, age at diagnosis and first distant or local recurrence were recorded. Results: L1CAM positive cases showed increased specificity for recurrence and these patients were significantly younger than L1CAM negative ones. Compared to L1CAM negative recurrent cases, L1CAM positive ones had a noticeably higher Ki-67, tended to be larger and recurred sooner. All L1CAM positive recurrent/metastatic cases were of the luminal B subtype compared to 67.3% of the L1CAM negative cases. Conclusions: L1CAM is highly specific for recurrence in a subset of breast cancer patients and may be associated with more aggressive behavior, particularly in luminal B breast cancers with higher Ki-67 expression. Further investigation about the prognostic value of L1CAM is warranted.

Published: August 2020

Abstract
Background: Our previous studies have demonstrated that Luks-PV have good anti-leukemia ability effects and could possibly be a promising therapy for adult acute myeloid leukemia (AML). Aberrant over-expression of HOXA9 is a prominent feature of AML driven by multiple oncogenes, and therapeutic degrading of HOXA9 may be an effective treatment strategy in AML. This paper focused on the Luks-PV-regulating autophagy pathway, aiming to investigate the role of Luks-PV in mixed-lineage leukemia (MLL)-rearranged AML. Methods: The data of leukemia patients were downloaded from the gene expression profiling of TCGA datasets. Taking primary AML and THP-1 cells as the model system in vitro, Luks-PV-inhibited cell proliferation was determined by CCK‐8 and flow cytometry assays. The role of Luks-PV in autophagy regulation was analyzed using immunoblotting, transfection and immunofluorescence.Results: HOXA9 was over-expressed and associated with a poor prognosis in AML patients bearing MLL rearrangement. After the application of pharmacologic inhibitors of autophagy, Luks-PV induced cytotoxic autophagy in AML cells, as suggested by biochemical and microscopy results. HOXA9 molecules were detectable within autophagosomes after Luks-PV treatment, indicating that autophagy induction accounted for the degradation of HOXA9. Moreover, Luks-PV-induced HOXA9 downregulation inhibited AML cell proliferation, suggesting that HOXA9 could be degraded through Luks-PV-induced autophagy.Conclusion: Luks-PV suppresses AML cell proliferation by inducing HOXA9 degradation.

Abstract
Background
Oral and maxillofacial surgery specialty has grown rapidly in Kuwait in recent years. However, the general public and healthcare professionals remain unaware of its expanding scope of practice. The aim of the study is to assess public and professional (dental and medical) perception of the oral and maxillofacial surgical specialty in Kuwait.
Methods
This is a cross-sectional study evaluating responses of dental professionals, medical professionals, and general public in Kuwait toward the oral and maxillofacial surgical specialty using a previously validated survey instrument with 100 participants in each group. Participants were asked to choose the most appropriate specialist to treat certain procedures across 4 disciplines: reconstruction, trauma, pathology, and cosmetic. Statistical comparison was conducted between dentists and medical doctors using Fisher’s exact test with a p-value of < 0.05.
Results
Disparities were noted each group’s responses. Oral and maxillofacial surgery was preferred overall for most clinical scenarios in trauma (p < 0.001), pathology (p < 0.001), and reconstructive surgery (p < 0.001). Plastic surgery was preferred for cosmetic surgeries (p < 0.001).
Conclusions
This study indicates the need to increase awareness and conduct health campaigns regarding oral and maxillofacial surgery among healthcare professionals, especially medical doctors, and the general public.

Abstract
As a serious malignancy with high incidence and fatality, non-small cell lung cancer (NSCLC) has affected millions of people each year worldwide. However, the 5-year survival rate of NSCLC is still not satisfactory. Therefore, it is particularly imperative and necessary to explore the underlying molecular mechanisms of NSCLC to contribute to the potential therapeutic targets and strategies. Six clinical samples including three normal tissues and three cancer tissues obtained from patients diagnosed with NSCLC were sequenced through Illumina Hiseq2500 sequencer. Differentially expressed lncRNAs and mRNAs analysis were implemented using the edgeR, and the function of differentially expressed lncRNAs and mRNAs were analyzed with GO and KEGG enrichment analysis. Then, top 10 dysregulated lncRNAs and mRNAs were screened out. Finally, the co-expression, biological function and pathway networks of dysregulated lncRNA with the predicted target genes were constructed. Differentially expressed lncRNAs and mRNAs could distinguish cancerous tissues from normal tissues. The functions and KEGG pathway of differentially expressed lncRNAs and mRNAs mainly were enriched in immune response, metabolism, phagosome, cytokine receptor interaction and IL-17 signaling pathway. The co-expression network revealed that top ten dysregulated lncRNAs were interacted with IGH gene cluster. Furthermore, the biological function and pathway network also indicated that dysregulated lncRNAs were involved in immune process. The results demonstrated that the biologic function of dysregulated lncRNAs that may be involved in immune process. Our data provides a foundation of the biologic significances of lncRNAs to contribute to the therapeutic targets and strategies for NSCLC to promote the survival for patients.

Abstract
Background: The burden of atrial fibrillation (AF) has been attractive recently and may be associated with stroke risk and mortality. Remote ischemic conditioning could reduce the incidence, inducibility and sustainability of AF. But the effects of chronic remote ischemic conditioning (CRIC) on atrial fibrillation burden in patients with pacemaker implanted are still unknown.Design: This was a single‑center, prospective, randomized, open-labeled clinical study.Methods: Sixty-six patients with permanent pacemakers were randomly divided into CRIC group and control group after 4 weeks screening. CRIC treatment was performed twice a day for 12 weeks. A remote ischemic conditioning protocol consisted of 4 × 5 min inflation/deflation of the blood pressure cuff applied in the upper arm to create intermittent arm ischemia. Pacemaker programming was performed for four times: before screening (-4-week), after screening and before randomization (0-week, baseline), 4-week and 12-week follow-up. Data including AF burden, longest duration of AF and cumulative numbers of atrial high-rate episodes (AHREs) were collected.Results: Sixty-one patients (31 patients in CRIC group and 30 patients in control group) completed the study. CRIC was well-tolerated by patients after 12 weeks treatment. The burden of AF in CRIC group was decreased significantly at 4-week compared with that at 0-week (14.7%±18.5% vs 17.0%±20.7%, p < 0.001), which further decreased at 12-week compared with that at 0-week (8.6%±10.2% vs 17.0%±20.7%, p < 0.001) and that at 4-week (8.6%±10.2% vs 14.7%±18.5%, p < 0.001), which was not observed in the control group. AF burden also reduced significantly after 12-week CRIC compared with that in control group (8.6%±10.2% vs 17.6%±19.5%, p = 0.013). Repeated measurement ANOVA showed that the changes of AF burden was associated with CRIC instead of time (p < 0.01). In addition, there were trends that longest duration of AF and cumulative numbers of AHREs were reduced after 12-week CRIC.Conclusions: This study suggests that a 12-week course of CRIC treatment could reduce AF burden in patients with permanent pacemakers, supporting widespread use of CRIC in the daily lives of these patients, which need to be verified in the future.Clinical Trial RegistrationRegistration name: Effects of remote ischemic conditioning on atrial fibrillation burden in patients with paroxysmal atrial fibrillationRegistration number: ChiCTR-IOR-17012666Registered 14 September 2017; URL: www.chictr.org.cn/showproj.aspx?proj=21591

Published: August 2020

Abstract
Background: Multimodal stroke imaging (Non-contrast CT, CT perfusion and CT angiogram) is essential to acute stroke assessment, there is currently no benchmark for this key process from real world data. Methods: Retrospective review of the turnaround time of consecutive multimodal imaging performed for acute stroke assessment at two high volume stroke centers in Australasia from July to September 2019.Results: 252 imaging studies were included from both sites. The overall median time from acquisition to imaging availability was 13 minutes (IQR 11- 16). The median for Christchurch and Box Hill were 11 minutes (IQR 10 – 12) and 15 minutes (IQR 13 – 19) respectively. Conclusions: Multimodal stroke imaging turnaround time of 11 minutes is a reasonable benchmark.

Abstract
Background: Diabetes is a risk factor for infection with coronaviruses. This study describes the demographic, clinical data and outcomes of critically ill patients with diabetes who developed Middle East Respiratory Syndrome (MERS).Methods: This retrospective cohort study was conducted at 14 hospitals in Saudi Arabia (September 2012-January 2018). We compared the demographic characteristics, underlying medical conditions, presenting symptoms and signs, management and clinical course and outcomes between critically ill MERS patients who had diabetes and those with no diabetes. Multivariable logistic regression analysis was performed to determine if diabetes was an independent predictor of 90-day mortality.Results: Of the 350 MERS patients, 171 (48.9%) had diabetes, were more likely to be older and have comorbid conditions. Patients with diabetes were more likely to present with respiratory failure requiring intubation, vasopressors and corticosteroids. The median time to clearance of MERS-CoV RNA was similar (23 days (Q1, Q3: 17, 36) in patients with diabetes and 21.0 days (Q1, Q3: 10, 33) in patients with no diabetes. Mortality at 90 days was higher in patients with diabetes (78.9% versus 54.7%, p<0.0001). Multivariable regression analysis showed that diabetes was an independent risk factor for 90-day mortality (odds ratio, 2.09; 95% confidence interval, 1.18-3.72).Conclusions: Critically ill patients with diabetes constitute half of critically ill patients with MERS, presenting with more severe disease requiring mechanical ventilation compared to those who do not have diabetes. Diabetes is an independent predictor of mortality.
