Evolution over 11 years of the characteristics of walk-in patients at the emergency department of a university hospital in Brussels.

Walk-in patients who do not require urgent treatment at an emergency department (ED) are a known and long-standing problem. This study aims to investigate the characteristics of walk-in patients visiting the ED over time. During four days in June 2012, all walk-in patients attending the ED of the University Hospital Brussels between 8 AM and 11 PM were recorded.

[Place of fibrates for the treatment of patients with atherogenic dyslipidemia].

The demography of dyslipidemia has changed towards a more complex atherogenic dyslipidemia involving increased levels of LDL cholesterol, in particular highly atherogenic small dense particles, hypertriglyceridemia and low HDL cholesterol, together with increased levels of markers of inflammation, thrombogenesis and endothelial dysfunction. Statins were shown to significantly lower cardiovascular morbidity and mortality, but treated patients are still left with a high residual risk, in particular for those with metabolic syndrome, type 2 diabetes, or low HDL cholesterol levels. Fibrates have been shown to reduce plasma triglycerides and increase HDL cholesterol, while improving inflammation, thrombogenesis and endothelial dysfunction.

Forced vital capacity and forced expiratory volume in six seconds as predictors of reduced total lung capacity.

The present study aims to derive guidelines that identify patients for whom spirometry can reliably predict a reduced total lung capacity (TLC). A total of 12,693 lung function tests were analysed on Caucasian subjects, aged 18-70 yrs. Restriction was defined as a reduced TLC.

Early detection of COPD: a case finding study in general practice.

Objectives: To estimate the prevalence of undiagnosed chronic obstructive pulmonary disease (COPD) in a population of general practice patients at risk for developing COPD. A further aim was to evaluate the presence of respiratory symptoms as a predictor for the diagnosis of COPD.

Methods: This study was conducted by eight general practitioners (GP) in six semi-rural general practices.

Obstructive and restrictive spirometric patterns: fixed cut-offs for FEV1/FEV6 and FEV6.

The purpose of this study was to determine fixed cut-off points for forced expiratory volume in one second (FEV(1))/FEV(6) and FEV(6) as an alternative for FEV(1)/forced vital capacity (FVC) and FVC in the detection of obstructive and restrictive spirometric patterns, respectively. For the study, a total of 11,676 spirometric examinations, which took place on Caucasian subjects aged between 20-80 yrs, were analysed. Receiver-operator characteristic curves were used to determine the FEV(1)/FEV(6) ratio and FEV(6) value that corresponded to the optimal combination of sensitivity and specificity, compared with the commonly used fixed cut-off term for FEV(1)/FVC and FVC.
