This study assessed symptoms and their determinants 1.5–6 months after symptom onset in non-hospitalised subjects with confirmed COVID-19 until 1 June 2020, a geographically defined area. We invited 938 subjects; 451 (48%) responded. They reported less than during COVID-19; median (IQR) 0 (0–2) versus 8 (6–11), respectively (p<0.001); 53% of women 67% men were free, while 16% dyspnoea, 12% loss/disturbance smell, 10% taste. In multivariable analysis, having persistent was associated the...

Despite side effects associated with the use of antiepileptic drugs (AEDs), withdrawal AEDs remains controversial, even after prolonged seizure freedom. The main objective this study was to assess AED on cognitive functions, relapse, health-related quality life (HRQOL), and EEG results. Additionally, potential predictors for freedom from seizures were studied.Patients, seizure-free more than 2 years monotherapy, recruited a controlled, prospective, randomized, double-blinded lasting 12...

Cutpoints (CPs) for mild, moderate and severe pain are established used primarily in cancer pain. In this study, we wanted to determine the optimal CPs moderate, joint replacement surgery candidates with osteoarthritis (OA) of hip or knee, validate different CPs.Patients (n = 353) completed Brief Pain Inventory (BPI), WOMAC Arthritis Index, SF-36 health status measure. Optimal categorizing average three severity levels were derived using multivariate analysis variance, CP sets as independent...

Lung function has been associated with mortality after adjusting for other risk factors; however, few studies have adjusted physical fitness and reported separate analyses according to smoking status. In 1972–1975, spirometry, clinical physiological parameters were recorded in 1,623 apparently healthy males aged 40–59 yrs. After 26 yrs of follow-up, the current authors investigated association between baseline lung mortality, smoking, potential factors. By 2000, 615 individuals (38%) had...
