Objective: The present study aimed to develop and evaluate a simple diagnostic model that could aid physicians to discriminate between infectious and non-infectious causes of fever of unknown origin (FUO).
Design/setting/subjects: Patients with classical FUO were studied in two distinct, prospective, observational phases. In the derivation phase that lasted from 1992 to 2000, 33 variables regarding demographic characteristics, history, symptoms, signs, and laboratory profile were recorded and considered in a logistic regression analysis using the diagnosis of infection as a dependent variable.
Background: Resistin (RSN) is an adipocytokine involved in insulin resistance, obesity and atherosclerosis. This study aimed to investigate the association between plasma RSN and outcome after ischemic stroke.
Methods: RSN measured within 24 h after the event was related to functional outcome and 5-year survival in 211 subjects with first-ever atherothrombotic ischemic stroke.
Background And Purpose: This study aimed to investigate the association between plasma adiponectin levels and 5-year survival after first-ever ischemic stroke.
Methods: Plasma adiponectin measured within 24 hours after first-ever ischemic stroke was related to 5-year outcome. The Kaplan-Meier technique was applied in survival analysis, and the Cox proportional hazards model was used to evaluate the relationship between risk factors and prognosis.
This study aimed (1) to develop a simple scoring system incorporating ultrasound (US) examination and clinical or laboratory predictors for increasing diagnostic accuracy in acute appendicitis (AA), and (2) to evaluate the performance of the scoring system as compared to that of previous models. Fifteen variables including US assessment for patients admitted with suspected AA were considered in multivariate analysis using the finding of AA at operation as the end point (internal study). The new score, together with 11 previous ones, was applied to a prospective independent population of subjects with suspected AA, and the respective performances were compared (external validation study).
View Article and Find Full Text PDFBackground: To formulate a classification tool for early recognition of patients admitted with acute pyelonephritis (AP) who are at high risk for failure of treatment or for death.
Methods: A retrospective chart review of 225 patients (102 men) admitted with AP. We considered 13 potential risk factors in a multivariate analysis.
Differentiation between patients with acute upper gastrointestinal bleeding who need early urgent upper gastrointestinal endoscopy and those who do not. A prospective study.
Eur J Gastroenterol Hepatol
April 2003
Objective: To differentiate, among patients presented at the emergency department with acute upper gastrointestinal bleeding, those who need early urgent upper gastrointestinal endoscopy from those who do not.
Methods: Seventeen variables for each patient presenting with upper gastrointestinal bleeding were prospectively recorded and considered in a multivariate analysis. We used the presence of active bleeding during early urgent upper gastrointestinal endoscopy within 12 h from admission as the end point.
Objective: To assess the association of serum CA 125 in patients with non-Hodgkin's lymphoma (NHL) with prognostic parameters of the disease, response to treatment, and survival.
Patients And Methods: Sixty-eight patients [38 males, median age 56 (range 17-82) yr] with NHL were evaluated. CA 125 was measured by an enzyme immunoradiometric assay at diagnosis and at the end of first-line treatment.
A mortality prediction model in diabetic ketoacidosis.
Clin Endocrinol (Oxf)
November 2002
Aim: To assess the value of clinical and laboratory parameters in predicting mortality in patients presenting with diabetic ketoacidosis (DKA).
Methods: The records of all DKA admissions within 10 years were reviewed. Eighteen variables were evaluated at initial presentation and 20 variables at 4, 12 and 24 h from admission.
