| 19 | Covid-19 pneumonia:Timing of pneumomediastinum and pneumothorax in 11 patients显示文摘Purpose:As the pandemic continues,many complications,previously recognized as rare,are now being reported as more than frequent complications of Covid-19 pneumonia.Of those,pneumomediastinum and pneumothorax are gaining attention.Their mechanism of occurrence/trigger is not fully understood,but the timing at which they occur is unclear.Methods:This is a case series of 11 Covid-19 patients with pneumomediastinum;retrospectively,we shed light on some of the patients’characteristics,the role of mechanical ventilation,and the timing of pneumomediastinum after initiation of mechanical ventilation.Results:We found that despite following the lung-protective strategy and despite keeping a plateau pressure at an acceptable range,most of our patients had an acute event around the same timing of mechanical ventilation.Conclusions:The similar timing raises questions about other risk factors that remain unknown.Timing and steroids can contribute to the higher incidence of these complications. | Mostafa Al Turk Maria Mitri Kawthar Jarrah Joanna Abi Chebl Georges Juvelekian | 2021 | Discussion of Clinical Cases2021，8，2： | 0 |
| 20 | Expression of the methylcytosine dioxygenase ten-eleven translocation-2 and connexin 43 in inflammatory bowel disease and colorectal cancer显示文摘BACKGROUND Inflammatory bowel disease(IBD)constitutes a substantial risk factor for colorectal cancer.Connexin 43(Cx43)is a protein that forms gap junction(GJ)complexes involved in intercellular communication,and its expression is altered under pathological conditions,such as IBD and cancer.Recent studies have implicated epigenetic processes modulating DNA methylation in the pathogenesis of diverse inflammatory and malignant diseases.The ten-eleven translocation-2(TET-2)enzyme catalyzes the demethylation,hence,regulating the activity of various cancer-promoting and tumor-suppressor genes.AIM To investigate Cx43 and TET-2 expression levels and presence of 5-hydroxymethylcytosine(5-hmC)marks under inflammatory conditions both in vitro and in vivo.METHODS TET-2 expression was evaluated in parental HT-29 cells and in HT-29 cells expressing low or high levels of Cx43,a putative tumor-suppressor gene whose expression varies in IBD and colorectal cancer,and which has been implicated in the inflammatory process and in tumor onset.The dextran sulfate sodium-induced colitis model was reproduced in BALB/c mice to evaluate the expression of TET-2 and Cx43 under inflammatory conditions in vivo.In addition,archived colon tissue sections from normal,IBD(ulcerative colitis),and sporadic colon adenocarcinoma patients were obtained and evaluated for the expression of TET-2 and Cx43.Expression levels were reported at the transcriptional level by quantitative real-time polymerase chain reaction,and at the translational level by Western blotting and immunofluorescence.RESULTS Under inflammatory conditions,Cx43 and TET-2 expression levels increased compared to noninflammatory conditions.TET-2 upregulation was more pronounced in Cx43-deficient cells.Moreover,colon tissue sections from normal,ulcerative colitis,and sporadic colon adenocarcinoma patients corroborated that Cx43 expression increased in IBD and decreased in adenocarcinoma,compared to tissues from non-IBD subjects.However,TET-2 expression and 5-hmC mark levels decreased in samples from patients with ulcerative colitis or cancer.Cx43 and TET-2 expression levels were also investigated in an experimental colitis mouse model.Interestingly,mice exposed to carbenoxolone(CBX),a GJ inhibitor,had upregulated TET-2 levels.Collectively,these results show that TET-2 levels and activity increased under inflammatory conditions,in cells downregulating gap junctional protein Cx43,and in colon tissues from mice exposed to CBX.CONCLUSION These results suggest that TET-2 expression levels,as well as Cx43 expression levels,are modulated in models of intestinal inflammation.We hypothesize that TET-2 may demethylate genes involved in inflammation and tumorigenesis,such as Cx43,potentially contributing to intestinal inflammation and associated carcinogenesis. | Mohammad El-Harakeh Jessica Saliba Kawthar Sharaf Aldeen May Haidar Layal El Hajjar Mireille Kallassy Awad Jana G Hashash Margret Shirinian Marwan El-Sabban | 2022 | World Journal of Gastroenterology2022，28，40： | 0 |
