BACKGROUND Advice from a medical expert on concerns and queries expressed anonymously through the Internet by patients and later posted on the Web, offers a new type of patient-doctor relationship. The aim of the current study was to perform a descriptive analysis of questions about AIDS and hepatitis made to an infectious disease expert and sent through(More)
BACKGROUND The level of staffing in hospitals is often lower on weekends than on weekdays, despite a presumably consistent day-to-day burden of disease. It is uncertain whether in-hospital mortality rates among patients with serious conditions differ according to whether they are admitted on a weekend or on a weekday. METHODS We analyzed all acute care(More)
BACKGROUND AND PURPOSE The goal of the present study was to examine a series of putative risk factors of poststroke dementia (PSD), especially those factors usually associated with cerebrovascular disease and degenerative dementia, in a series of 251 consecutive unselected stroke patients. METHODS A standard protocol was prospectively applied at admission(More)
BACKGROUND The history of venous thromboembolism (VTE), and the rationale for thromboprophylaxis in surgical patients are well understood. The situation is less clear for acutely ill medical patients. OBJECTIVES To compare the clinical presentation of VTE and clinical outcomes of immobile acutely ill medical patients with surgical patients. PATIENTS(More)
BACKGROUND Some reports have shown that the risk of death is higher for patients admitted on weekends than for patients who go into the hospital on weekdays. This study was conducted to assess what independent influence, if any, weekend admission might have on mortality in our hospital. METHODS The clinical data of 35,993 adult (>14 years) patients(More)
BACKGROUND Data evaluating the safety of using weight-based dosing of low-molecular-weight heparin (LMWH) in either underweight or obese patients with venous thromboembolism (VTE) are limited. Thus, recommendations based on evidence from clinical trials might not be suitable for patients with extreme body weight. PATIENTS AND METHODS Patients with(More)
BACKGROUND AND PURPOSE Cognitive decline occurs in approximately 30% of stroke patients. Acute risk factors have been identified, but long-term risk has not been examined in large samples. The purpose of this research was to determine factors associated with the progression of cognitive impairment after stroke. METHODS Consecutive stroke patients (193)(More)
BACKGROUND Current guidelines make no specific recommendations for venous thromboembolism (VTE) treatment in patients with renal insufficiency, but some experts recommend some reduction in heparin dose. METHODS Registro Informatizado de Enfermedad TromboEmbólica (RIETE) is an ongoing, prospective registry of consecutively enrolled patients with(More)
BACKGROUND The relationship between body mass index (BMI) and mortality in patients with established arterial disease remains controversial. METHODS FRENA is an ongoing, observational registry of consecutive outpatients with coronary artery disease (CAD), cerebrovascular disease, or peripheral artery disease (PAD). We examined the prognostic importance of(More)
