| 1 | Fatty liver disease in severe obese patients:Diagnostic value of abdominal ultrasound显示文摘AIM:To evaluate the sensitivity and specificity of abdominal ultrasound (US) for the diagnosis of hepatic steatosis in severe obese subjects and its relation to histological grade of steatosis. METHODS: A consecutive series of obese patients, who underwent bariatric surgery from October 2004 to May 2005, was selected. Ultrasonography was performed in all patients as part of routine preoperative time and an intraoperative wedge biopsy was obtained at the beginning of the bariatric surgery. The US and histological findings of steatosis were compared, considering histology as the gold standard. RESULTS: The study included 105 patients. The mean age was 37.2 ± 10.6 years and 75.2% were female. The histological prevalence of steatosis was 89.5%. The sensitivity and specificity of US in the diagnosis of hepatic steatosis were, respectively, 64.9% (95% CI: 54.9-74.3) and 90.9% (95% CI: 57.1-99.5). The positive predictive value and negative predictive value were, respectively, 98.4% (95% CI: 90.2-99.9) and 23.3% (95% CI: 12.3-39.0). The presence of steatosis onUS was associated to advanced grades of steatosis on histology (P = 0.016). CONCLUSION: Preoperative abdominal US in our series has not shown to be an accurate method for the diagnosis of hepatic steatosis in severe obese patients. Until another non-invasive method demonstrates better sensitivity and specificity values, histological evaluation may be recommended to these patients undergoing bariatric surgery. | Alessandro de Moura Almeida Helma Pinchemel Cotrim Daniel Batista Valente Barbosa Luciana Gordilho Matteoni de Athayde Adimeia Souza Santos Almir Galvo Vieira Bitencourt Luiz Antonio Rodrigues de Freitas Adriano Rios Erivaldo Alves | 2008 | World Journal of Gastroenterology2008，14，9： | 10 |
| 2 | Effect of Graphene Nanoplatelets Presence on the Thermal and Mechanical Properties of Polypropylene Fibers Produced by Melt Spinning显示文摘In aiming to obtain fibers with enhanced thermal and mechanical properties,graphene based textile fibers with 144 filaments were developed using an approach in which the PP/GnP(polypropylene/graphene nanoplatelets)nanocomposite was employed as conductive material in a fiber with circular cross-section geometry.The kinetics of thermal degradation was evaluated by the Broido method using thermogravimetric analysis(TGA).Activation energy was enhanced from 260.6 kJ·mol^-1 to 337.4 kJ·mol^-1 compared to the neat PP.GnP increased the thermal stability of the PP,slowing its degradation by thermal depolymerization.Furthermore,the degree of crystallization declined as the GnP content increased,reducing the tenacity of the yarn,but improving its elastic modulus from 91.9 to 95.9 cN/tex,being a promising alternative to produce smart textiles.In conclusion,it has been confirmed that GnP loading up to 1%(w/w)can be incorporated into polypropylene by melt spinning and that the resulting nanocomposite fibers are suitable for several applications in the textile industry. | Ricardo Rodrigo Ramos Cecci Adriano Alves Passos Nathan Riany Valério Albino Daniel da Silva Vicente Ademir Severino Duarte Maria Inês Bruno Tavares | 2020 | 材料科学与工程(中英文B版)2020，10，2： | 1 |

| 6 | Hospitalizations and in-hospital mortality for inflammatory bowel disease in Brazil显示文摘BACKGROUND Inflammatory bowel disease(IBD)is associated with complications,frequent hospitalizations,surgery and death.The introduction of biologic drugs into the therapeutic arsenal in the last two decades,combined with an expansion of immunosuppressant therapy,has changed IBD management and may have altered the profile of hospitalizations and in-hospital mortality(IHM)due to IBD.AIM To describe hospitalizations from 2008 to 2018 and to analyze IHM from 1998 to 2017 for IBD in Brazil.METHODS This observational,retrospective,ecological study used secondary data on hospitalizations for IBD in Brazil for 2008-2018 to describe hospitalizations and for 1998-2017 to analyze IHM.Hospitalization data were obtained from the Hospital Information System of the Brazilian Unified Health System and population data from demographic censuses.The following variables were analyzed:Number of deaths and hospitalizations,length of hospital stay,financial costs of hospitalization,sex,age,ethnicity and type of hospital admission.RESULTS There was a reduction in the number of IBD hospitalizations,from 6975 admissions in 1998 to 4113 in 2017(trend:y=-0.1682x+342.8;R^(2)=0.8197;P<0.0001).The hospitalization rate also decreased,from 3.60/100000 in 2000 to 2.17 in 2010.IHM rates varied during the 20-year period,between 2.06 in 2017 and 3.64 in 2007,and did not follow a linear trend(y=-0.0005049x+2.617;R^(2)=0,00006;P=0.9741).IHM rates also varied between regions,increasing in all but the southeast,which showed a decreasing trend(y=-0.1122x+4.427;R^(2)=0,728;P<0.0001).The Southeast region accounted for 44.29%of all hospitalizations.The Northeast region had the highest IHM rate(2.86 deaths/100 admissions),with an increasing trend(y=0.1105x+1.110;R^(2)=0.6265;P<0.0001),but the lowest hospitalization rate(1.15).The Midwest and South regions had the highest hospitalization rates(3.27 and 3.17,respectively).A higher IHM rate was observed for nonelective admissions(2.88),which accounted for 81%of IBD hospitalizations.The total cost of IBD hospitalizations in 2017 exhibited an increase of 37.5%compared to 2008.CONCLUSION There has been a notable reduction in the number of hospitalizations for IBD in Brazil over 20 years.IHM rates varied and did not follow a linear trend. | Ana Luiza Vilar Guedes Amanda Lopes Lorentz Larissa Fernandes de Almeida Rios Rios Beatriz Camara Freitas Adriano Gutemberg Neves Dias Ana Luísa Eckhard Uhlein Felipe Oliveira Vieira Neto Jobson Felipe Soares Jesus Túlio de SáNovaes Torres Raquel Rocha Vitor D Andrade Genoile Oliveira Santana | 2022 | World Journal of Gastrointestinal Pharmacology and Therapeutics2022，13，1： | 0 |
