BACKGROUND If carotid artery narrowing remains asymptomatic (ie, has caused no recent stroke or other neurological symptoms), successful carotid endarterectomy (CEA) reduces stroke incidence for some years. We assessed the long-term effects of successful CEA. METHODS Between 1993 and 2003, 3120 asymptomatic patients from 126 centres in 30 countries were allocated equally, by blinded minimised...

BACKGROUND Clinical outcomes after stent placement in patients with a history of metal allergy remain incompletely understood. We performed a single-center retrospective study to evaluate such outcomes. METHODS AND RESULTS Twenty-nine allergic patients who underwent coronary stent implantation were compared with a nonallergic group (n=250) matched for demographics and a propensity score for a...
BACKGROUND Total mesorectal excision (TME) remains commonplace for T1-2 rectal cancer owing to fear of undertreating a small proportion of patients with node-positive disease. Molecular stratification may predict cancer progression. It could be used to select patients for organ-preserving surgery if specific biomarkers were validated. METHODS Gene methylation was quantified using bisulphite p...
Thin films of binary Bi 0 -TeO and Bi 0 -V 0 systems were prepared by the thermal co-evaporation technique in a vacuum at room temperature. The optical absorption edge of these systems are studied in the wavelength of 200-800 nm using a PERKIN-ELMER uv/Vis spectrophotometer. It is found that the value of n=3/2 in the Davis-Mott equation is best fitted for the fundamental absorption edge f...
BACKGROUND The impact of nodal disease remains controversial in papillary thyroid carcinoma (PTC). STUDY DESIGN One surgeon treated 159 unselected patients, who were followed up for 1 to 27 years. We present a retrospective analysis with respect to nodal disease. Occult nodal disease was investigated, including metachronous nodal disease (mpN(1)) in primarily node negative patients (pN(0), cl...
INTRODUCTION The aim of this study was to examine the impact of gout on quality of life (QOL) and study differences by gender and race. METHODS Ten race- and sex-stratified nominal groups were conducted, oversampling for African-Americans and women with gout. Patients presented, discussed, combined and rank-ordered their concerns. RESULTS A total of 62 patients with mean age 65.1 years, 60%...
Chronic fatigue syndrome (CFS) is a heterogeneous disorder of unknown aetiology characterized by disabling fatigue, headaches, sleep disturbance and several other symptoms. The onset of CFS may follow a viral infection or period of stress. Patients with CFS do not have hypogammaglobulinaemia, predisposition to recurrent bacterial infections or symptoms of autoimmunity. To date, defects in B cel...
این پژوهش به بررسی عملکرد خوانندگان متون زبان انگلیسی به عنوان یک زبان خارجی در پاسخگویی به سوالات استنباطی جزئی و کلی با در نظر گرفتن سطح بسندگی زبانی آنها می پردازد. ارتباط میان توانایی خواندن و توانایی استنباط نیز سنجیده شده است. به منظور یافتن پاسخ این سوالات، دو آزمون در فاصله زمانی دو هفته برگزار شد. ابتدا آزمون مهارت زبانی ارائه شد. سپس، یک آزمون خواندن شامل سوالات استنباطی و متنی برگزار...
