1Foveal avascular zone area and parafoveal vessel density measurements in different stages of diabetic retinopathy by optical coherence tomography angiography显示文摘AIM:To investigate foveal avascular zone(FAZ) and parafoveal vessel densities(PRVD) by means of optical coherence tomography angiography(OCTA) in diabetic patients with or without diabetic retinopathy(DR) and to assess the reproducibility of FAZ and PRVD measurements.METHODS:Sixty diabetic patients(60 eyes) with different stage of DR(graded according to the International Clinical Severity Scale for DR) and 20 healthy subjects underwent FAZ area and PRVD measurements using OCTA by two experienced examiners.FAZ area in all patients was also assessed using fluorescein angiography(FA).RESULTS:In subject with proliferative DR and with moderate-severe non proliferative DR,FAZ area was significantly increased compared to healthy controls(P=0.025 and P=0.050 respectively measured with OCTA and P=0.025 and P=0.048 respectively measured with FA).OCTA showed significantly less inter-observer variability compared to FA.Concordance correlation coefficient(CCC) for FAZ area measurements was 0.829(95%CI:0.736-0.891) P<0.001 with FA and 1.000(95%CI:0.999-1.000) P<0.001 with OCTA.CCC was 0.834(95%CI:0.746-0.893) P<0.001 and 0.890(95%CI:0.828-0.930) P<0.001 for parafoveal superficial and deep vessel density measurements,respectively.CONCLUSION:OCTA shows progressive increase of FAZ area and reduction of PRVD in both superficial and deep plexus at increasing DR severity.FAZ area and PRVD measurements using OCTA are highly reproducible.Rodolfo Mastropasqua Lisa Toto Alessandra Mastropasqua Raffaella Aloia Chiara De Nicola Peter A Mattei Guido Di Marzio Marta Di Nicola Luca Di Antonio 2017International Journal of Ophthalmology(English edition)2017,10,10:26
2Systemic inflammation and immune response after laparotomy vs laparoscopy in patients with acute cholecystitis, complicated by peritonitis显示文摘AIM: To evaluate acute cholecystitis, complicated by peritonitis, acute phase response and immunological status in patients treated by laparoscopic or open approach. METHODS: From January 2002 to May 2012, we conducted a prospective randomized study on 45 consecutive patients (27 women, 18 men; mean age 58 years). These subjects were taken from a total of 681 patients who were hospitalised presenting similar preoperative findings: acute upper abdominal pain with tenderness, involuntary guarding under the right hypochondrium and/or in the flank; fever higher than 38 ℃, leukocytosis greater than 10 × 10 9 /L or both, and ultrasonographic evidence of calculous cholecystitis possibly complicated by peritonitis. These patients had undergone cholecystectomy for acute calculous cholecystitis,complicated by bile peritonitis. Randomly, 23 patients were assigned to laparoscopic cholecystectomy (LC), and 22 patients to open cholecystectomy (OC). Blood samples were collected from all patients before operation and at days 1, 3 and 6 after surgery. Serum bacteraemia, endotoxaemia, white blood cells (WBCs), WBC subpopulations, human leukocyte antigen-DR (HLA-DR), neutrophil elastase, interleukin-1 (IL-1) and IL-6, and C-reactive protein (CRP) were measured at 0, 30, 60, 90, 120 and 180 min, at 4, 6, 12, 24 h, and then daily (8 A.M.) until post-operative day 6.RESULTS: The two groups were comparable in the severity of peritoneal contamination as indicated by the viable bacterial count (open group = 90% of positive cultures vs laparoscopic group = 87%) and endotoxin level (open group = 33.21 ± 6.32 pg/mL vs laparoscopic group = 35.02 ± 7.23 pg/mL). Four subjects in the OC group (18.1%) and 1 subject (4.3%) in the LC group (P < 0.05) developed intra-abdominal abscess. Severe leukocytosis (range 15.8-19.6/mL) was observed only after OC but not after LC, mostly due to an increase in neutrophils (days 1 and 3, P < 0.05). This value returned to the normal range within 3-4 d after LC and 5-7 d after OC. Other WBC types and lymphocyte subpopulations showed no significant variation. On the first day after surgery, a statistically significant difference was observed in HLA-DR expression between LC (13.0 ± 5.2) and OC (6.0 ± 4.2) (P < 0.05). A statistically significant change in plasma elastase concentration was recorded post-operatively at days 1, 3, and 6 in patients from the OC group when compared to the LC group (P < 0.05). In the OC group, the serum levels of IL-1 and IL-6 began to increase considerably from the first to the sixth hour after surgery. In the LC group, the increase of serum IL-1 and IL-6 levels was delayed and the peak values were notably lower than those in the OC group. Significant differences between the groups, for these two cytokines, were observed from the second to the twenty-fourth hour (P < 0.05) after surgery. The mean values of serum CRP in the LC group on post-operative days (1 and 3) were also lower than those in the OC group (P < 0.05). Systemic concentration of endotoxin was higher in the OC group at all intra-operative sampling times, but reached significance only when the gallbladder was removed (OC group = 36.81 ± 6.4 ρg/mLvs LC group = 16.74 ± 4.1 ρg/mL, P < 0.05). One hour after surgery, microbiological analysis of blood cultures detected 7 different bacterial species after laparotomy, and 4 species after laparoscopy (P < 0.05). CONCLUSION: OC increased the incidence of bacteraemia, endotoxaemia and systemic inflammation compared with LC and caused lower transient immunological defense, leading to enhanced sepsis in the patients examined.Federico Sista Mario Schietroma Giuseppe De Santis Antonella Mattei Emanuela Marina Cecilia Federica Piccione Sergio Leardi Francesco Carlei Gianfranco Amicucci 2013World Journal of Gastrointestinal Surgery2013,5,4:23
3Ten years of sorafenib in hepatocellular carcinoma: Are there any predictive and/or prognostic markers?显示文摘Sorafenib has been considered the standard of care for patients with advanced unresectable hepatocellular carcinoma(HCC) since 2007 and numerous studieshave investigated the role of markers involved in the angiogenesis process at both the expression and genetic level and clinical aspect. What results have ten years of research produced? Several clinical and biological markers are associated with prognosis. The most interesting clinical parameters are adverse events, Barcelona Clinic Liver Cancer stage, and macroscopic vascular invasion, while several single nucleotide polymorphisms and plasma angiopoietin-2 levels represent the most promising biological biomarkers. A recent pooled analysis of two phase III randomized trials showed that the neutrophil-to-lymphocyte ratio, etiology and extra-hepatic spread are predictive factors of response to sorafenib, but did not identify any predictive biological markers. After 10 years of research into sorafenib there are still no validated prognostic or predictive factors of response to the drug in HCC. The aim of the present review was to summarize 10 years of research into sorafenib, looking in particular at the potential of associated clinical and biological markers to predict its efficacy in patients with advanced HCC.Giorgia Marisi Alessandro Cucchetti Paola Ulivi Matteo Canale Giuseppe Cabibbo Leonardo Solaini Francesco G Foschi Serena De Matteis Giorgio Ercolani Martina Valgiusti Giovanni L Frassineti Mario Scartozzi Andrea Casadei Gardini 2018World Journal of Gastroenterology2018,24,36:14

5全球法与掠夺:法治的阴暗面显示文摘'法治'(rule of law),习惯上已被当作一个具有积极本质、政治中立的'工具',且效力普适,放之四海而皆准。作为Ugo Mattei与Laura Nadar教授合著的Plunder:When the Ruleof Law is Illegal(Blackwell Publishing,Oxford 2008)一书观点的综述,本文认为,作为一个歧义丛生的概念,'法治'具有光明与阴暗的两面性,而'法治'的阴暗面长期以来一直被排除在公众讨论的范围之外。'法治'作为一个华丽辞藻,已被西方强势者所挟持,用来论证其(主要)对'发展中'国家的干涉及其最终演变成的掠夺(plunder)实践的合法性,并使西方经济势力对'非西方世界'(the rest)的扩张成为可能。基于此,我们得出了这样的结论:'法治'已被'非法地'(illegally)利用。目前国际金融机构——当今的全球立法者——在用'法治'观念包裹着其提供给'发展中世界'的各种改革方案的背后,隐藏着智识短视、种族中心主义和帝国主义立场。'技术性'概念对'法'概念的偷换,美国法所独享的全球性支配地位以及当今西方跨国公司的帝国主义态度等作为其中的一些指标,向我们展示了殖民主义与当今新自由主义政策之间的沆瀣一气。Ugo Mattei Marco de Morpurgo 刘光华(译) 2010兰州大学学报(社会科学版)2010,38,3:10
6Biotribology of artificial hip joints显示文摘Hip arthroplasty can be considered one of the major successes of orthopedic surgery, with more than 350000 replacements performed every year in the United States with a constantly increasing rate. The main limitations to the lifespan of these devices are due to tribological aspects, in particular the wear of mating surfaces, which implies a loss of matter and modification of surface geometry. However, wear is a complex phenomenon, also involving lubrication and friction. The present paper deals with the tribological performance of hip implants and is organized in to three main sections. Firstly, the basic elements of tribology are presented, from contact mechanics of ball-in-socket joints to ultra high molecular weight polyethylene wear laws. Some fundamental equations are also reported, with the aim of providingthe reader with some simple tools for tribological investigations. In the second section, the focus moves to artificial hip joints, defining materials and geometrical properties and discussing their friction, lubrication and wear characteristics. In particular, the features of different couplings, from metal-on-plastic to metal-on-metal and ceramic-on-ceramic, are discussed as well as the role of the head radius and clearance. How friction, lubrication and wear are interconnected and most of all how they are specific for each loading and kinematic condition is highlighted. Thus, the significant differences in patients and their lifestyles account for the high dispersion of clinical data. Furthermore, such consideration has raised a new discussion on the most suitable in vitro tests for hip implants as simplified gait cycles can be too far from effective implant working conditions. In the third section, the trends of hip implants in the years from 2003 to 2012 provided by the National Joint Registry of England, Wales and Northern Ireland are summarized and commented on in a discussion.Francesca Di Puccio Lorenza Mattei 2015World Journal of Orthopedics2015,6,1:8
7Fertility preservation in female cancer patients:a single center experience显示文摘Advances in cancer treatment allow women to be cured and live longer. However, the necessary chemotherapy and radiotherapy regimens have a negative impact on future fertility. Oncofertility has emerged as a new interdisciplinary field to address the issue of gonadotoxicity associated with cancer treatment and to facilitate fertility preservation, including oocyte and ovarian tissue cryopreservation. These fertility issues are often inadequately addressed, and referral rates to oncofertility centers are low. The aim of this study was to report the 3-year experience of the San Raffaele Oncofertility Unit. A total of 96 patients were referred to the Oncofertility Unit for evaluation after the diagnosis of cancer and before gonadotoxic treatment between April 2011 and June 2014. Of the 96 patients, 30(31.2%) were affected by breast cancers, 20(20.8%) by sarcomas, 28(29.2%) by hematologic malignancies, 13(13.5%) by central nervous system cancers, 3(3.1%) by bowel tumors, 1(1.0%) by Wilms' tumor, and 1(1.0%) by a thyroid tumor; 47(49.0%) were referred for oocyte cryopreservation before starting chemotherapy, 20(20.8%) were referred for ovarian tissue cryopreservation, and 29(30.2%) were not recruited. The mean time between the patients' counseling and oocyte retrieval was 15 days(range, 2–37 days). The mean time between the laparoscopic surgery and the beginning of treatment was 4 days(range, 2–10 days). The number of patients who were referred increased over time, whereas the rate of patients who were not recruited decreased, showing an improvement in referrals to the Oncofertility Unit and in the patients' counseling and understanding. Our results indicate that an effective multidisciplinary oncofertility team is necessary for prompt referrals and treatment.Cristina Sigismondi Enrico Papaleo Paola Viganò Simona Vailati Massimo Candiani Jessica Ottolina Valentina E.
