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

3Analysis on Critical Success Factors for Agile Manufacturing Evaluation in Original Equipment Manufacturing Industry-An AHP Approach显示文摘Manufacturing industries are facing challenges in the implementation of agile manufacturing in their products and processes.Agility is widely accepted as a new competitive concept in the manufacturing sector in fulfilling varying customer demand. Thus,evaluation of agile manufacturing in industries has become a necessity. The success of an organisation depends on its ability to manage finding the critical success factors and give them special and continued attention in order to bring about high performance. This paper proposes a set of critical success factors(CSFs) for evaluating agile manufacturing considered appropriate for the manufacturing sector.The analytical hierarchy process(AHP) method is applied for prioritizing the success factors, by summarizing the opinions of experts. It is believed that the proposed CSFs enable and assist manufacturing industries to achieve a higher performance in agile manufacturing so as to increase competitiveness.C Ajay Guru Dev V S Senthil Kumar 2016Chinese Journal of Mechanical Engineering2016,29,5:7
4Critical role of OX40 signaling in the TCR-independent phase of human and murine thymic Treg generation显示文摘Regulatory T cells(Tregs)play a pivotal role in immune-tolerance,and loss of Treg function can lead to the development of autoimmunity.Natural Tregs generated in the thymus substantially contribute to the Treg pool in the periphery,where they suppress self-reactive effector T cells(Teff)responses.Recently,we showed that OX40L(TNFSF4)is able to drive selective proliferation of peripheral Tregs independent of canonical antigen presentation(CAP-independent)in the presence of low-dose IL-2.Therefore,we hypothesized that OX40 signaling might be integral to the TCR-independent phase of murine and human thymic Treg(tTreg)development.Development of tTregs is a two-step process:Strong T-cell receptor(TCR)signals in combination with co-signals from the TNFRSF members facilitate tTreg precursor selection,followed by a TCR-independent phase of tTreg development in which their maturation is driven by IL-2.Therefore,we investigated whether OX40 signaling could also play a critical role in the TCR-independent phase of tTreg development.OX40−/−mice had significantly reduced numbers of CD25−Foxp3low tTreg precursors and CD25+Foxp3+mature tTregs,while OX40L treatment of WT mice induced significant proliferation of these cell subsets.Relative to tTeff cells,OX40 was expressed at higher levels in both murine and human tTreg precursors and mature tTregs.In ex vivo cultures,OX40L increased tTreg maturation and induced CAP-independent proliferation of both murine and human tTregs,which was mediated through the activation of AKT-mTOR signaling.These novel findings show an evolutionarily conserved role for OX40 signaling in tTreg development and proliferation,and might enable the development of novel strategies to increase Tregs and suppress autoimmunity.Prabhakaran Kumar Alejandra Marinelarena Divya Raghunathan Vandhana K Ragothaman Shikha Saini Palash Bhattacharya Jilao Fan Alan L Epstein Ajay V Maker Bellur S Prabhakar 2019Cellular & Molecular Immunology2019,16,2:4
5Laparoscopic vs open partial colectomy in elderly patients:Insights from the American College of Surgeons- National Surgical Quality Improvement Program database显示文摘AIM: To compare the outcomes between the laparoscopic and open approaches for partial colectomy in elderly patients aged 65 years and over using the American College of Surgeons- National Surgical Quality Improvement Program(ACS NSQIP) database. METHODS: The ACS NSQIP database for the years 2005-2011 was queried for all patients 65 years and above who underwent partial colectomy. 1:1 propensity score matching using the nearest- neighbor method was performed to ensure both groups had similar preoperative comorbidities. Outcomes including postoperative complications, length of stay and mortality were compared between the laparoscopic and open groups. χ2 and Fisher's exact test were used for discrete variables and Student's t-test for continuous variables. P < 0.05 was considered significant and odds ratios with 95%CI were reported when applicable. RESULTS: The total number of patients in the ACS NSQIP database of the years 2005-2011 was 1777035. We identified 27604 elderly patients who underwent partial colectomy with complete data sets. 12009(43%) of the cases were done laparoscopically and15595(57%) were done with open. After propensity score matching, there were 11008 patients each in the laparoscopic(LC) and open colectomy(OC) cohorts. The laparoscopic approach had lower post-operative complications(LC 15.2%, OC 23.8%, P < 0.001), shorter length of stay(LC 6.61 d, OC 9.62 d, P < 0.001) and lower mortality(LC 1.6%, OC 2.9%, P < 0.001). CONCLUSION: Even after propensity score matching, elderly patients in the ACS NSQIP database having a laparoscopic partial colectomy had better outcomes than those having open colectomies. In the absence of specific contraindications, elderly patients requiring a partial colectomy should be offered the laparoscopic approach.Umashankkar Kannan Vemuru Sunil K Reddy Amar N Mukerji Vellore S Parithivel Ajay K Shah Brian F Gilchrist Daniel T Farkas 2015World Journal of Gastroenterology2015,21,45:3

7Current scenario of traditional medicines in management of diabetic foot ulcers:A review显示文摘Diabetic foot infections and diabetic foot ulcers(DFU)cause significant suffering and are often recurring.DFU have three important pathogenic factors,namely,microangiopathy causing local tissue anoxia,neuropathy making the foot prone to injuries from trivial trauma,and local tissue hyperglycaemia favouring infection and delaying the wound healing.DFU have been the leading cause for non-traumatic amputations of part or whole of the limb.Western medicines focus mainly on euglycaemia,antimicrobials,debridement and wound cover with grafts,and off-loading techniques.Advances in euglycaemic control,foot care and footwear,systemic antimicrobial therapy,and overall health care access and delivery,have resulted in an overall decrease in amputations.However,the process of wound care after adequate debridement remains a major cost burden globally,especially in developing nations.This process revolves around two basic concerns regarding control/eradication of local infection and promotion of faster healing in a chronic DFU without recurrence.Wound modulation with various dressings and techniques are often a costly affair.Some aspects of the topical therapy with modern/Western medicines are frequently not addressed.Cost of and compliance to these therapies are important as both the wounds and their treatment are“chronic.”Naturally occurring agents/medications from traditional medicine systems have been used frequently in different cultures and nations,though without adequate clinical base/relevance.Traditional Chinese medicine involves restoring yin-yang balance,regulating the‘chi’,and promoting local blood circulation.Traditional medicines from India have been emphasizing on‘naturally’available products to control wound infection and promote all the aspects of wound healing.There is one more group of chemicals which are not pharmaceutical agents but can create acidic milieu in the wound to satisfy the above-mentioned basic concerns.Various natural and plant derived products(e.g.,honey,aloe vera,oils,and calendula)and maggots are also used for wound healing purposes.We believe that patients with a chronic wound are so tired physically,emotionally,and financially that they usually accept native traditional medicine which has the same cultural base,belief,and faith.Many of these products have never been tested in accordance to“evidence-based medicine.”There are usually case reports and experience-based reports about these products.Recently,there have been some trials(in vitro and in vivo)to verify the claims of usage of traditional medicines in management of DFU.Such studies show that these natural products enhance the healing process by controlling infection,stimulating granulation tissue,antimicrobial action,promoting fibroblastic activity and collagen deposition,etc.In this review,we attempt to study and analyse the available literature on results of topical traditional medicines,which are usually advocated in the management of DFU.An integrated and‘holistic’approach of both modern and traditional medicine may be more acceptable to the patient,cost effective,and easy to administer and monitor.This may also nevertheless lead to further improvement in quality of life and decrease in the rates of amputations for DFU.Abhijit S Rayate Basavraj S Nagoba Sachin S Mumbre Hardi B Mavani Ajay M Gavkare Advait S Deshpande 2023World Journal of Diabetes2023,14,1:3
