BACKGROUND The erosion of the early mortality advantage of elective endovascular aneurysm repair (EVAR) compared with open repair of abdominal aortic aneurysm remains without a satisfactory explanation. METHODS An individual-patient data meta-analysis of four multicentre randomized trials of EVAR versus open repair was conducted to a prespecified analysis plan, reporting on mortality, aneurys...
Icatibant is used to treat acute hereditary angioedema with C1 inhibitor deficiency types I/II (C1-INH-HAE types I/II) and has shown promise in angioedema due to acquired C1 inhibitor deficiency (C1-INH-AAE). Data from the Icatibant Outcome Survey (IOS) were analysed to evaluate the effectiveness of icatibant in the treatment of patients with C1-INH-AAE and compare disease characteristics with ...

نانوذرات مغناطیسی فریت نیکل- منگنز- مس عمدتأ در دارورسانی مغناطیسی، محیط های مغناطیسی ضبط داده ها، حسگرهای گازی، مدارهای فرکانس بالا و ذخیره اطلاعات و ... کاربرد فراوانی دارند. در این پایان نامه نانوذرات مغناطیسی فریت نیکل - منگنز - مس با درصدهای متفاوت جانشانی مس به جای منگنز به روش هم رسوبی شیمیایی تهیه شدند و خواص ساختاری، مغناطیسی و الکتریکی آنها مورد مطالعه و بررسی قرارگرفت. برای مشخصه یاب...
BACKGROUND The impact of neuraminidase inhibitors (NAIs) on influenza-related pneumonia (IRP) is not established. Our objective was to investigate the association between NAI treatment and IRP incidence and outcomes in patients hospitalised with A(H1N1)pdm09 virus infection. METHODS A worldwide meta-analysis of individual participant data from 20 634 hospitalised patients with laboratory-conf...
In an observational cohort study, we found that adults hospitalized for oseltamivir-resistant (H275Y) seasonal H1N1 influenza (n = 46) were older than those infected with oseltamivir-susceptible strains (n = 31) [74(IQR 59-83) versus 64(IQR 48-76) years; P = 0·045], and most had major comorbidities (78% versus 65%). Disease severity and clinical outcomes were comparable between the two groups: ...
BACKGROUND Patient-specific instrumentation in TKA has the proposed benefits of improving coronal and sagittal alignment and rotation of the components. In contrast, the literature is inconsistent if the use of patient-specific instrumentation improves alignment in comparison to conventional instrumentation. Depending on the manufacturer, patient-specific instrumentation is based on either MRI ...
