BACKGROUND & AIM Bariatric surgery is a valid treatment option for persons with non-alcoholic fatty liver disease. This study prospectively examined the impact of laparoscopic sleeve gastrectomy (LSG) on liver histopathology, and blood levels of adiponectin, leptin, resistin, and pre-B cell enhancing factor/Nampt/visfatin. PATIENTS & METHODS In 81 patients with non-alcoholic fatty liver disease who underwent LSG, paired liver biopsies and blood specimens were obtained before and 18 months after LSG. Differences between preoperative and 18 months postoperative data were tested by paired Student's t-test or Wilcoxon rank test as appropriate. RESULTS At follow up, there was a significant improvement in biochemical markers for glucose homeostasis, including fasting glucose, HbA1c, insulin levels, and homeostatic model assessment index. Postoperative liver function tests, namely serum alanine aminotransferase, aspartate aminotransferase, and gamma-glutamyl transpeptidase level, showed a significant improvement compared to before weight loss. The number of patients who had definite, borderline, or no non-alcoholic steatohepatitis was 43 (53%), 27 (33%), and 11 (14%), respectively, at baseline, and 9 (11%), 32 (40%), and 40 (49%) at 18-month post-surgery follow up. A significant reduction in steatosis, liver fibrosis, lobular inflammation, and hepatocyte ballooning was observed in the postoperative biopsies (P  less then  0.001 each). In addition, at the follow-up assessment, there was a significant increase in serum adiponectin levels and significant decline in serum levels of leptin, resisitin, and pre-B cell enhancing factor/Nampt/visfatin. CONCLUSION Weight loss after sleeve gastrectomy was associated with a significant improvement in several metabolic parameters, liver enzyme levels, liver histopathology, and changes in serum adipokine levels towards antidiabetic and anti-inflammatory profiles. © 2020 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.Hepatocellular carcinoma (HCC) is the fifth most common cancer worldwide and the third most frequent cause of cancer-related death. The IRX5 transcription factor plays a different role in multiple cancers and contributes to the development of many tumours. However, little is known about the molecular mechanisms of IRX5 in HCC. In this study, we found that IRX5 was abnormally upregulated in HCC tissues compared with adjacent normal tissues. IRX5 promoted HCC cell proliferation and upregulated the expression of cyclin D1 and knockdown of IRX5 suppressed tumorigenicity in vivo. Furthermore, knockdown of IRX5 increased p53 and Bax expression and decreased Bcl-2 expression. Thus, IRX5 suppressed apoptosis in HCC cells by inhibiting the p53 signalling pathway, indicating its role as a treatment target for HCC.

We investigated whether navigated reconstruction could decrease the complication rate and optimize outcomes. METHODS A retrospective study was conducted on 33 patients who underwent acetabular resection and reconstruction with ice-cream cone prostheses; outcomes were compared between the navigated and nonnavigated groups. RESULTS A clear margin was obtained in 91% and 82% of the navigated and nonnavigated groups, respectively. The local recurrence (LR) rate was 12%, and all LRs occurred in the nonnavigated group. The rate of major complications requiring surgical intervention was significantly lower in the navigated group (9%) than in the nonnavigated group (50%; P = .024). Two implant failures occurred in the nonnavigated group. Functional outcomes were significantly correlated with the occurrence of major complications (P = .010) and the use of navigation (P = .043); superior functional scores were observed in the navigated group (Musculoskeletal Tumor Society, 73% vs 55%; Toronto Extremity Salvage Score, 73% vs 56%). CONCLUSION Ice-cream cone prosthesis is an acceptable reconstruction modality following periacetabular tumor resections, and computer navigation are useful to facilitate proper resection margins and implant position. © 2020 Wiley Periodicals, Inc.BACKGROUND Hepatic metastases are a major cause of death in patients with colorectal cancer. A comprehensive assessment of the prognostic factors associated with long-term survival could improve patient selection for surgical approaches and decrease morbidity and futile locoregional treatments. METHODS We performed a retrospective analysis of patients who underwent hepatectomy for colorectal liver metastases at a single center from 2000 to 2012. RESULTS To identify factors associated with 5- and 10-year overall (OS) and disease-free survival (DFS), we analyzed 280 patients and 150 patients in the 5- and 10-year cohorts, respectively. Only seven relapses occurred after 5 years of follow-up, and no relapses occurred after 10 years. Multivariable analysis indicated that bilobar disease and extra-hepatic disease before hepatectomy were independent 5- and 10-year predictors of OS, and major postoperative complications predicted OS in the 5-year survival cohort only. Our analysis indicated that prognostic factors associated with DFS included some confounders and was therefore inconclusive. CONCLUSIONS Taken together, our results suggest that the predictors of 5- and 10-year OS rates of colorectal cancer patients with hepatic metastases are similar, differing only by postoperative complications that influenced exclusively 5-year survival. https://www.selleckchem.com/products/mi-773-sar405838.html Since no relapse occurred 10 years after hepatic resection, oncological remission is likely. © 2020 Wiley Periodicals, Inc.

87, P 9 kPa. Shear-wave-speed dispersion showed a high correlation with fibrosis (r = 0.85, P less then 0.0001), whereas there was a very weak correlation with steatosis. CONCLUSIONS The results of this study show that this 2-dimensional-shear wave elastography technique is accurate for staging liver fibrosis. Shear-wave-speed dispersion is highly correlated with liver fibrosis but not with steatosis.AIM Patients with acute-on-chronic liver failure (ACLF) have a high risk of developing infections while hospitalized. Nosocomial bloodstream infection (BSI) is not uncommon, particular in patients who receive invasive operation, which may have negative impact on prognosis. In this study, we aim to investigate the characteristics and short-term outcome of nosocomial BSI in patients with ACLF. METHODS Sixty-three patients with ACLF and nosocomial BSI from January 2014 to December 2015 were retrospectively studied. Clinical characteristics and distribution of bacteria at the time of BSI onset and short-term mortality were collected. RESULTS The most common etiology of ACLF was hepatitis B virus infection. Eighty-one percent of ACLF patients had other types of infections at BSI onset. Gram-negative bacteria (77.8%) were the main pathogens, among which Escherichia coli was responsible for 46.9%. Staphylococcus epidermidis was the main Gram-positive bacteria. The most prevalent multidrug resistance (MDR) bacteria was extended-spectrum β-lactamase (ESBL)-producing E. coli. The overall 28-day mortality rate was 42.9%. Multivariate analysis found that model for end-stage liver disease (MELD) score and number of organ failures were predictors of 28-day mortality. https://www.selleckchem.com/products/Tretinoin(Aberela).html The area under the receiver operating characteristic of the numbers of organ failures to predict 28-day mortality was higher than MELD score (0.833 vs. 0.784, 0.4099), but without significant difference. CONCLUSION Gram-negative bacteria were the most prevalent pathogens and ESBL-producing bacteria were responsible for most of the MDR bacteria in patients with ACLF and nosocomial BSI. Higher MELD score and multiorgan failure were associated with worse outcomes.PURPOSE The aim of this study was to examine electron microscopic features of canalicular concretions obtained from patients with canaliculiths. METHODS Canalicular concretions were obtained from 10 patients diagnosed as canaliculiths and were immediately fixed for ultrastructural analysis. Surface structure and transmission electron microscopical sections were studied. Multiple longitudinal and transverse ultrathin sections were obtained at different levels and all were studied using standard protocols of scanning electron microscopy and transmission electron microscopy. RESULTS Three different types of canalicular concretions were noted; predominantly coccoid and bacilloid, predominantly filamentous, and mixed varieties. The surfaces and the cut sections showed typical and distinctive features for each of the concretion types. The filamentous subtypes were common accounting for 50% (5/10) of all canalicular concretions. The surface of predominantly filamentous concretions revealed typical honeycomb patterns, the walls and base of which were formed by definitive and peculiar arrangement of Actinomyces. Transmission electron microscopy confirmed the findings of scanning electron microscopy and demonstrated typical structural features of Actinomyces and some other bacteria undergoing binary fission. The most interesting feature was the lack of immune cells and blood products within the substance of canalicular concretions as compared with the mucopeptide concretions. CONCLUSIONS Ultrastructural features of canalicular concretions reveal 3 distinct microbial subtypes and opens up avenues toward better understanding of the etiopathogenesis of canaliculiths and possible structural resistance to host defenses or antibiotics.Adenoid cystic carcinoma (ACC) of the eyelid is a very rare tumor, and only 11 cases have been previously reported in the literature. Here the authors report the 12th case of eyelid ACC that was initially diagnosed as adenoid basal cell carcinoma. This is the first report of local recurrence after wide local excision using the Mohs technique. Additionally, this is the first report that demonstrates that ACC can present clinically and histologically similar to basal cell carcinoma. The authors summarize the previous reports of eyelid ACC to compile a reference for this growing body of literature. It is important for oculoplastic surgeons and dermatopathologists to keep ACC in the differential diagnosis of eyelid tumors and carefully examine histology specimens with this differential in mind.Escherichia coli canaliculitis is an exceptionally rare organism to cause primary canaliculitis. The present case describes unilateral canaliculitis refractory to conventional therapy with a significant history of recurrent culture proven E. coli urinary tract infection. Microbiological analysis revealed E. coli bacilli and histological examination showed goblet cell metaplasia, subepithelial edema with acute and chronic inflammatory infiltrate. The possibility of an endogenous infection or autoinoculation secondary to urinary tract infection cannot be ruled out.A 22-year-old male presented with spontaneous unilateral hemolacria and was found to have complete opacification of the ipsilateral nasolacrimal sac and duct. Endoscopic biopsy with histopathologic analysis revealed the diagnosis of nasolacrimal lymphangioma. Additional management included nasolacrimal stenting, and there was no hemolacria recurrence or epiphora. This is the first report of a nasolacrimal lymphangioma and describes the vascular malformation as a potential cause of bloody tearing.The purpose of this case series is to report the demographic profile, indications, anatomical considerations, and outcomes of Endonasal endoscopic DCR in the infants. Five eyes of 3 infants underwent IEnDCR with a mean age of 4.26 months (range 23 days-8 months). There were 2 males and 1 female. Two of the infants underwent bilateral surgery. The indication for surgery in the infant undergoing unilateral surgery was recurrent acute dacryocystitis and lacrimal abscess formation secondary to refractory and complex congenital nasolacrimal duct obstruction. Infants undergoing bilateral lacrimal surgery had refractory complex congenital nasolacrimal duct obstruction and were in need for an early intraocular surgery for associated ocular morbidities. Mitomycin-C (0.02% for 3 minutes) and silicone intubation was used in all cases. At follow up of 9 months, all the 3 infants demonstrated anatomical and functional success. The surgical technique requires certain modifications in order to cater to the unique challenges.
