OBJECTIVE Bilateral transverse thoracosternotomy (clamshell incision) is a widely used approach in bilateral sequential lung transplantation, but the closure technique is associated with sternal dehiscence. This study compares the incidence of sternal dehiscence between the crossed and uncrossed closure techniques. METHODS In 129 patients who underwent(More)
PURPOSE The objective of our study was to identify prognostic social factors in the subacute phase after stroke for the discharge destination from the hospital stroke-unit. METHODS A systematic literature search was performed, designed in accordance with the Cochrane Collaboration criteria. Internal, statistical and external validity of the studies were(More)
BACKGROUND In non-thromboembolic pulmonary hypertension, endothelin (ET)-1 levels are increased and correlate with the hemodynamic severity of the disease. Whether such correlations exist in chronic thromboembolic pulmonary hypertension (CTEPH) is unknown, nor whether ET-1 levels correlate with hemodynamic outcome after pulmonary endarterectomy (PEA).

OBJECTIVE To investigate which factors during the subacute phase post stroke have predictive value for the discharge outcome from the hospital stroke unit. METHODS In a prospective cohort of 338 patients admitted to a hospital stroke unit 26 potentially prognostic factors, arranged in clinical and social subdomains, were scored and analysed by binary(More)
Multiple aspects of gait are typically impaired post-stroke. Asymmetric gait is common as a consequence of unilateral brain lesions. The relationship between the resulting asymmetric gait and impairments in the ability to properly coordinate the reciprocal stepping activation of the legs is not clear. The objective of this exploratory study is to quantify(More)
The opening of data is considered to provide many benefits. However, opening up data by public bodies is a complex and ill-understood activity. Although many public bodies might be willing to open up their data, they lack any systematic guidance. In this paper, guidance is provided by investigating the publishing processes at the Dutch Research and(More)
Information sharing has become a means of gaining public trust for institutions such as governmental and scientific organizations. The transparency sought through information sharing contributes to the trust of various stakeholders such as citizens, other organizations and enterprises in such institutions. Information sharing, on the other hand, may(More)
BACKGROUND Despite its frequency and impact, delirium is poorly recognized in postoperative and critically ill patients. EEG is highly sensitive to delirium but, as currently used, it is not diagnostic. To develop an EEG-based tool for delirium detection with a limited number of electrodes, we determined the optimal electrode derivation and EEG(More)
