1Transarterial chemoembolization using degradable starch microspheres and iodized oil in the treatment of advanced hepatocellular carcinoma: evaluation of tumor response, toxicity, and survival显示文摘BACKGROUND: In a multidisciplinary conference patients with advanced non-resectable hepatocellular carcinoma (HCC) were stratified according to their clinical status and tumor extent to different regional modalities or to best supportive care. The present study evaluated all patients who were stratified to repeated transarterial chemoembolization (TACE) from 1999 until 2003 in terms of tumor response, toxicity, and survival. A moderate embolizing approach was chosen using a combination of degradable starch microspheres (DSM) and iodized oil (Lipiodol) in order to combine anti-tumoral efficiency and low toxicity. METHODS: Fourty-seven patients were followed up prospectively. TACE treatment consisted of cisplatin (50 mg/m2), doxorubicin (50 mg/m2), 450-900 mg DSM, and 5-30 ml Lipiodol. DSM and Lipiodol were administered according to tumor vascularization. Patient characteristics,toxicity, and complications were outlined. In multivariate regression analyses of pre-treatment variables from a prospective database, predictors for tumor response and survival after TACE were determined. RESULTS: 112 TACE courses were performed (2.4±1.5 courses per patient). Mean maximum tumor size was 75 (± 43) mm, in 68% there was bilobar disease. Best response to TACE treatment was: progressive disease (PD) 9%, stable disease (SD) 55%, partial remission (PR) 36%, and complete remission (CR) 0%. Multivariate regression analyses identified tumor size ≤75 mm, tumor number ≤5, and tumor hypervascularization as predictors for PR. The overall 1-, 2-, and 3-year-survival rates were 75%, 59%, and 41%, respectively, and the median survival was 26 months. Low α-fetoprotein levels (<400 ng/ml) (Odds ratio=3.3) and PR as best response to TACE (Odds ratio=6.7) were significantly associated with long term survival (>30 months, R2=36%). Grade 3 toxicity occurred in 7.1% (n=8), and grade 4 toxicity in 3.6% (n=4) of all courses in terms of reversible leukopenia and thrombocytopenia. The incidence of major complications was 5.4% (n=6). All complications were managed conservatively. The mortality within 6 weeks after TACE was 2.1% (one patient). CONCLUSIONS: DSM and Lipiodol were combined successfully in the palliative TACE treatment of advanced HCC resulting in high rates of tumor response and survival at limited toxicity. Favourable tumor response was associated with tumor extent and vascularization. TACE using DSM and Lipiodol can be considered a suitable palliative measure in patients who might not tolerate long acting embolizing agents.Timm D Kirchhoff Joerg S Bleck Arne Dettmer Ajay Chavan Herbert Rosenthal Sonja Merkesdal Bernd Frericks Lars Zender Nisar P Malek Tim F Greten Stefan Kubicka Michael P Manns Michael Galanski 2007Hepatobiliary & Pancreatic Diseases International2007,6,3:15

3Gastrointestinal neuroendocrine tumors treated with high dose octreotide-LAR:A systematic literature review显示文摘AIM:To review literature on efficacy and safety of octreotide-long-acting repeatable(LAR)used at doses higher than the Food and Drug Administration(FDA)-approved 30 mg/mo for treatment of neuroendocrine tumors(NETs).METHODS:We searched Pub Med and Cochrane Library from 1998-2012,5 conferences(American Society of Clinical Oncology,Endocrine Society,European Neuroendocrine Tumor Society,European Society for Medical Oncology,North American Neuroendocrine Tumor Society)from 2000-2013 using Me SH and keyterms including neuroendocrine tumors,carcinoid tumor,carcinoma,neuroendocrine,and octreotide.Bibliographies of accepted articles were also searched.Two reviewers reviewed titles,abstracts,and full-length articles.Studies that reported data on efficacy and safety of≥30 mg/mo octreotide-LAR for NETs in human subjects,published in any language were included in the review.RESULTS:The search identified 1086 publications,of which 238 underwent full-text review(20 were translated into English);17 were included in the review.Studies varied in designs,subjects,octreotide-LAR regimens,and definition of outcomes.Eleven studies reported use of higher doses to control symptoms and tumor progression,although symptom severity and formal quality-of-life analysis were not quantitatively measured.Ten studies reported efficacy,describing 260 subjects with doses ranging from 40 mg/mo or 30 mg/3 wk up to 120 mg/mo.Eight studies reported expert clinical opinion that supported dose escalation of octreotide-LAR up to 60 mg/mo for symptom control and suggested increased doses may be effective at preventing tumor progression.Eight studies reported safety;there was no evidence of increased toxicity associated with doses of octreotide-LAR>30 mg/mo.CONCLUSION:As reported in this review,octreotide-LAR at doses>30 mg/mo is being prescribed for symptom and tumor control in NET patients.Furthermore,expert clinical opinion provided support for escalation of somatostatin analogs for refractory hormonal symptoms.Michael S Broder David Beenhouwer Jonathan R Strosberg Maureen P Neary Dasha Cherepanov 2015World Journal of Gastroenterology2015,21,6:8
4Metabolic and hepatic effects of liraglutide,obeticholic acid and elafibranor in diet-induced obese mouse models of biopsy-confirmed nonalcoholic steatohepatitis显示文摘AIM To evaluate the pharmacodynamics of compounds in clinical development for nonalcoholic steatohepatitis(NASH) in obese mouse models of biopsy-confirmedNASH.METHODS Male wild-type C57 BL/6 J mice(DIO-NASH) and Lep^(ob/ob)(ob/ob-NASH) mice were fed a diet high in trans-fat(40%), fructose(20%) and cholesterol(2%) for 30 and 21 wk, respectively. Prior to treatment, all mice underwent liver biopsy for confirmation and stratification of liver steatosis and fibrosis, using the nonalcoholic fatty liver disease activity score(NAS) and fibrosis staging system. The mice were kept on the diet and received vehicle, liraglutide(0.2 mg/kg, SC, BID), obeticholic acid(OCA, 30 mg/kg PO, QD), or elafibranor(30 mg/kg PO, QD) for eight weeks. Within-subject comparisons were performed on changes in steatosis, inflammation, ballooning degeneration, and fibrosis scores. In addition, compound effects were evaluated by quantitative liver histology, including percent fractional area of liver fat, galectin-3, and collagen 1 a1.RESULTS Liraglutide and elafibranor, but not OCA, reduced body weight in both models. Liraglutide improved steatosis scores in DIO-NASH mice only. Elafibranor and OCA reduced histopathological scores of hepatic steatosis and inflammation in both models, but only elafibranor reduced fibrosis severity. Liraglutide and OCA reduced total liver fat, collagen 1 a1, and galectin-3 content, driven by significant reductions in liver weight. The individual drug effects on NASH histological endpoints were supported by global gene expression(RNA sequencing) and liver lipid biochemistry.CONCLUSION DIO-NASH and ob/ob-NASH mouse models show distinct treatment effects of liraglutide, OCA, and elafibranor, being in general agreement with corresponding findings in clinical trials for NASH. The present data therefore further supports the clinical translatability and utility of DIO-NASH and ob/ob-NASH mouse models of NASH for probing the therapeutic efficacy of compounds in preclinical drug development for NASH.Kirstine S Tolbol Maria NB Kristiansen Henrik H Hansen Sanne S Veidal Kristoffer TG Rigbolt Matthew P Gillum Jacob Jelsing Niels Vrang Michael Feigh 2018World Journal of Gastroenterology2018,24,2:5
5Economic impact of minimally invasive lumbar surgery显示文摘Cost effectiveness has been demonstrated for traditional lumbar discectomy, lumbar laminectomy as well as for instrumented and noninstrumented arthrodesis. While emerging evidence suggests that minimally invasive spine surgery reduces morbidity, duration of hospitalization, and accelerates return to activites of daily living, data regarding cost effectiveness of these novel techniques is limited. The current study analyzes all available data on minimally invasive techniques for lumbar discectomy, decompression, short-segment fusion and deformity surgery. In general, minimallyinvasive spine procedures appear to hold promise in quicker patient recovery times and earlier return to work. Thus, minimally invasive lumbar spine surgery appears to have the potential to be a cost-effective intervention. Moreover, novel less invasive procedures are less destabilizing and may therefore be utilized in certain indications that traditionally required arthrodesis procedures. However, there is a lack of studies analyzing the economic impact of minimally invasive spine surgery. Future studies are necessary to confirm the durability and further define indications for minimally invasive lumbar spine procedures.Christoph P Hofstetter Anna S Hofer Michael Y Wang 2015World Journal of Orthopedics2015,6,2:4

7Is there a role of lipid-lowering therapies in the management of fatty liver disease?显示文摘Atherogenic dyslipidemia is characterized by increased triglyceride-rich lipoproteins and low high-density lipoprotein cholesterol concentrations.It is highly prevalent in non-alcoholic fatty liver disease(NAFLD)and contributes to the increased cardiovascular risk associated with this condition.Alongside insulin resistance it plays an important pathogenetic role in NAFLD/non-alcoholic steatohepatitis(NASH)development and progression.It has been shown that cholesterol-lowering reduces cardiovascular risk more in NAFLD vs non-NAFLD high-risk individuals.This evidence highlights the importance of effective lipid modulation in NAFLD.In this narrative review the effects of the most commonly used lipid-lowering therapies on liver outcomes alongside their therapeutic implications in NAFLD/NASH are critically discussed.Preclinical and clinical evidence suggests that statins reduce hepatic steatosis,inflammation and fibrosis in patients with NAFLD/NASH.Most data are derived from observational and small prospective clinical studies using changes in liver enzyme activities,steatosis/fibrosis scores,and imaging evidence of steatosis as surrogates.Also,relevant histologic benefits were noted in small biopsy studies.Atorvastatin and rosuvastatin showed greater benefits,whereas data for other statins are scarce and sometimes conflicting.Similar studies to those of statins showed efficacy of ezetimibe against hepatic steatosis.However,no significant anti-inflammatory and anti-fibrotic actions of ezetimibe have been shown.Preclinical studies showed that fibrates through peroxisome proliferator-activated receptor(PPAR)αactivation may have a role in NAFLD prevention and management.Nevertheless,no relevant benefits have been noted in human studies.Species-related differences in PPARαexpression and its activation responsiveness may help explain this discrepancy.Omega-3 fatty acids reduced hepatic steatosis in numerous heterogeneous studies,but their benefits on hepatic inflammation and fibrosis have not been established.Promising preliminary data for the highly purified eicosapentaenoic acid require further confirmation.Observational studies suggest that proprotein convertase subtilisin/kexin9 inhibitors may also have a role in the management of NAFLD,though this needs to be established by future prospective studies.Ismini Tzanaki Aris P Agouridis Michael S Kostapanos 2022World Journal of Hepatology2022,14,1:2
8Outcomes after arthroscopic repair of rotator cuff tears in the setting of mild to moderate glenohumeral osteoarthritis显示文摘BACKGROUND Rotator cuff pathology is a very common source of shoulder pain.Similarly,osteoarthritis of the glenohumeral joint can cause shoulder pain and produce similar symptoms.Surgical management can be indicated for both pathologies,however,outcomes data is limited when examining rotator cuff repair(RCR) in the setting of glenohumeral arthritis(GHOA).Thus,this study sought to determine outcomes for patients who undergo RCR in the setting of GHOA.AIM To evaluate if a relationship exists between outcomes of RCR in the setting of GHOA.METHODS This was a retrospective analysis of patients who underwent arthroscopic rotator cuff repair with concurrent glenohumeral osteoarthritis between 2010-2017.Patients were stratified based on rotator cuff tear size and glenohumeral osteoarthritis severity.Cohorts were paired 1:1 with patients without glenohumeral osteoarthritis.Patients included had a minimum two year follow-up.Rate of conversion to total shoulder arthroplasty,complication rates following initial surgery,and patient-reported outcome measures were collected.RESULTS A total of 142 patients were included.The number of patients that required total shoulder arthroplasty within two years after index surgery was low.2/71(2.8%) patients with GHOA,and 1/71(1.4%) without GHOA.Following rotator cuff repair,both groups showed favorable patientreported outcomes.CONCLUSION Patients with glenohumeral osteoarthritis who underwent arthroscopic rotator cuff repair showed comparable outcomes to patients without glenohumeral osteoarthritis.Ian S Hong Allison J Rao Tyler L CarlLee Joshua D Meade Daniel J Hurwit Gregory Scarola David P Trofa Shadley C Schiffern Nady Hamid Patrick M Connor James E Fleischli Bryan Michael Saltzman 2022World Journal of Orthopedics2022,13,7:2
