Ustekinumab showed a better overall drug survival than etanercept, and a trend towards a better overall drug survival than adalimumab. After 1 year, patients reported to be 'happy' in 79% of episodes and 'unhappy' in 21%. We introduced the new concept of 'happy' drug survival because the proportion of on-drug patients with good quality of life is an important indicator for treatment success.

Ustekinumab has the highest confounder-corrected long-term drug survival in psoriasis treatment, compared with adalimumab and etanercept. Higher BMI is a predictor for discontinuation due to ineffectiveness in etanercept and ustekinumab, and female sex is a consistent predictor for discontinuation due to side-effects in all three outpatient biologics.

Objective To study whether stopping elastic compression stockings (ECS) after 12 months is non-inferior to continuing them for 24 months after proximal deep venous thrombosis.Design Multicentre single blind non-inferiority randomised controlled trial.Setting Outpatient clinics in eight teaching hospitals in the Netherlands, including one university medical centre.Participants Patients compliant with compression therapy for 12 months after symptomatic, ultrasound proven proximal deep venous thrombosis of the leg.Interventions Continuation or cessation of ECS 12 months after deep venous thrombosis.Main outcome measures The primary outcome was the incidence of post-thrombotic syndrome 24 months after diagnosis of deep venous thrombosis, as assessed by the standardised Villalta scale in an intention to treat analysis. The predefined non-inferiority margin was 10%. The main secondary outcome was quality of life (VEINES-QOL/Sym).Results 518 patients compliant with ECS and free of post-thrombotic syndrome were randomised one year after diagnosis of deep venous thrombosis to stop or continue ECS therapy for another year. In the stop-ECS group, 51 of 256 patients developed post-thrombotic syndrome, with an incidence of 19.9% (95% confidence interval 16% to 24%). In the continue-ECS group, 34 of 262 patients developed post-thrombotic syndrome (incidence 13.0%, 9.9% to 17%), of whom 85% used ECS six or seven days a week during the study period, for an absolute difference of 6.9% (95% confidence interval upper limit 12.3%). Because the upper limit of the 95% confidence interval exceeds the predefined margin of 10%, non-inferiority was not reached. The number needed to treat to prevent one case of post-thrombotic syndrome by continuing ECS was 14 (95% confidence interval lower limit 8). Quality of life did not differ between the two groups.Conclusion Stopping ECS after one year in compliant patients with proximal deep venous thrombosis seemed not to be non-inferior to continuing ECS therapy for two years in this non-inferiority trial.Trial registration Netherlands Trial Register NTR1442.

A limited number of patients achieved PASI 100 or PASI 90 at 24 weeks of biological treatment. Including an absolute PASI score in the assessment of psoriasis severity is important. Baseline BMI was an important, modifiable predictor for a high response.

Compared with etanercept, ustekinumab had the highest effectiveness during 5 years of treatment. Patients receiving adalimumab and ustekinumab more often reached PASI 75 than those on etanercept at 1 year of treatment. Dose escalation was more frequent in etanercept and adalimumab than in ustekinumab.
