    Juschten, J. (Jenny)
    SUMMARY INTRODUCTION Acute respiratory distress syndrome (ARDS) is characterized by hypoxemic respiratory failure following an either direct (e.g. pneumonia) or indirect (e.g. sepsis) pulmonary insult. Dealing with hypoxemia remains the major challenge at bedside and is currently approached with lung-protective mechanical ventilation since specific treatment targeting the pathogenesis of ARDS is lacking. Pathological hallmarks of ARDS are uncontrolled inflammation and coagulation leading to alve....................
    (2017-01-01) Colorectal cancer risk in a nationwide inflammatory bowel disease cohort with indefinite for dysplasia and low grade dysplasia
    Tilburg, S. van (Sanne)
    Introduction: Patients with long-standing colonic inflammatory bowel disease (IBD) bear an increased colorectal cancer (CRC) risk. Endoscopic surveillance allows early detection and removal of precancerous lesions such as indefinite for dysplasia (IND) and low-grade dysplasia (LGD), and may subsequently prevent CRC. However, the long-term outcome after LGD and the subsequent risk to develop CRC remains uncertain, since most available studies are small and cover a relatively short follow-up perio....................
    (2017-01-01) Preformed donor specific antibody class II and its effects on graft outcome after kidney transplantation
    Uffing, A. (Audrey)
    Most kidney transplant centers in the United States of America currently exclude all potential recipients with a donor-specific antibody (DSA), by listing them as unacceptable human leukocyte antigen (HLA) on the deceased donor list. However, the role of preformed DSA class II in graft outcome is not clear and its exclusion significantly reduces the chance of finding compatible donors for highly sensitized patients. In this retrospective cohort, we assessed the effect of preformed donor-specific....................
    (2017-01-01) Verlaging van de loading rate van de verticale grondreactiekracht tijdens hardlopen door middel van feedback: een pilotstudie
    Vrielink, J.W.
    Introduction The rate at which the gound reaction force (vGRF) increases in vertical direction (Loading Rate; LR) seems to be of importance in the onset of running injuries. Runners may experience fewer injuries when the LR is reduced by 10-15%, feedback focused on gait retraining appears to provide such reduction. There are two different types of gait retraining feedback, the first one depends on the information from a person’s own body (internal focus) while the other feedback depends on inf....................

    Bakker, J. (Joanne)
    Background: In Thailand, the prevalence of cardiovascular disease (CVD) increased excessively during the past decades and is the leading cause of death. Left ventricular hypertrophy (LVH) can be seen on electrocardiogram (ECG) and is associated with poor cardiovascular outcome, but no incremental predictive value is seen when putting LVH in a traditional predicting model. Most studies on this specific subject were performed in Western populations. However, because Asians have a higher prevalence....................
    (2017-01-01) Long-term outcome after pelvic and acetabular fractures : Does age matter?
    Banierink, H. (Hester)
    Background. Fractures of the pelvis and acetabulum are serious injuries, mostly caused by high-energy traumas or due to osteoporosis in the elderly. The fracture type varies from a simple fracture with no instability of the pelvis, to life-threatening “open book” fractures. The ring structure of the pelvis makes isolated fractures rare and gives a high risk of associated acetabular fractures. Pelvic and acetabular fractures can be treated either conservatively or surgically, depending on the....................
