This pilot study suggests that midodrine is not as effective as intravenous albumin in preventing circulatory dysfunction after large-volume paracentesis in patients with cirrhosis and tense ascites, especially with HCC-positive patients.

Wound healing is a well-organized dynamic process involving coordinated consecutive phases: homeostasis, inflammation, proliferation and resolution. Fibroblasts play major roles in skin wound healing such as in wound contraction and release of growth factors which are of importance in angiogenesis and tissue remodeling. Abnormal fibroblast phenotypes have been identified in patients with chronic wounds. In this work, we analyzed scRNA-seq datasets of normal and wounded skin from mice at day 4 post-wound to investigate fibroblast heterogeneity during the proliferative phase of wound healing. Compositional analysis revealed a specific subset of fibroblast (cluster 3) that primarily increased in wounded skin (14%) compared to normal skin (3.9%). This subset was characterized by a gene signature marked by the plasma membrane proteins Sfrp2 + Sfrp4 + Sfrp1 + and the transcription factors Ebf1 + Prrx1 + Maged1 + . Differential gene expression and enrichment analysis identified epithelial to mesenchymal transition (EMT) and angiogenesis to be upregulated in the emerging subset of fibroblasts of the wounded skin. Using two other datasets for murine wounded skin confirmed the increase in cluster 3-like fibroblasts at days 2, 7 and 14 post-wounding with a peak at day 7. By performing a similarity check between the differential gene expression profile between wounded and normal skin for this emerging fibroblast subset with drug signature from the ConnectivityMap database, we identified drugs capable of mimicking the observed gene expression change in fibroblasts during wound healing. TTNPB, verteprofin and nicotinic acid were identified as candidate drugs capable of inducing fibroblast gene expression profile necessary for wound healing. On the other hand, methocarbamol, ifosfamide and penbutolol were recognized to antagonize the identified fibroblast differential expression profile during wound healing which might cause delay in wound healing. Taken together, analysis of murine transcriptomic skin wound healing datasets suggested a subset of fibroblasts capable of inducing EMT and further inferred drugs that might be tested as potential candidates to induce wound closure.

BACKGROUND Bowel ultrasound and magnetic resonance enterography (MRE) are decisive medical imaging modalities for diagnosing and locating bowel lesions with its extramural extent and complications. They assess the degree of activity, help clinicians to identify patients in need of surgery, and can be used for patient follow-up. AIM To compare the role of MRE and bowel ultrasound in diagnosis and follow-up of inflammatory bowel disease (IBD) patients in Egypt. METHODS The study was conducted on 40 patients with IBD. All patients were subjected to clinical assessment, laboratory investigations, bowel ultrasound, MRE, and colonoscopy up to the terminal ileum with biopsies for histopathological examination. RESULTS This study was conducted on 14 patients (35%) with ulcerative colitis and 26 patients (65%) with Crohn's disease; 34 (85%) of these patients had active disease. Bowel ultrasound detected different bowel lesions with the following accuracies: ileum (85%), large bowel (70%), fistula (95%), stricture and proximal dilatation (95%) and abscesses (100%). Also, it showed that statistically significance of bowel ultrasound in differentiation between remission and activity of IBD in comparison to MRE and colonoscopy. CONCLUSION In comparison to MRE, bowel ultrasound is a useful, non-invasive, and feasible bedside imaging tool for the detection of inflammation, detection of complications, and follow-up of IBD patients when performed by the attending physician.

Background: Hepatitis C virus treatment has dramatically improved by direct-acting antiviral (DAA) therapy. The aim of this study was to assess the efficacy and safety of DAA in elderly Egyptian chronic hepatitis C (CHC) patients. Methods: The study was carried out on 327 CHC elderly patients >60 years; patients were divided into 3 age subgroups (<65, 65–75 and >75 years) on DAA therapy for 12 weeks. Ninety-one patients (27.8%) were treated with dual therapy, 234 patients (71.6%) with triple therapy and 2 patients (0.6%) with quadrable therapy. Results: All patients achieved end-of-treatment virological response (100%). ALT levels normalized during therapy. The follow-up rate of sustained virological response at 12 weeks after the end of treatment (SVR12) was 100%. One hundred and two patients had missed SVR12 data due to being lost tofollow-up. Two hundred twenty-two adverse events were reported (67.8%), including anemia in 30 patients (9.1%), leucopenia in 129 patients (39.4%) and thrombocytopenia in 63 patients (19.2%). No serious side effects led to discontinuation of therapy. No hepatic decompensation was observed, and no patients died. Conclusion: Age does not influence the success of DAA treatment and all DAA regimens are well tolerated, safe and highly efficacious, even in those aged 75 years or older.
