Vgamma9/Vdelta2 T cells are a minor subset of T cells in human blood and differ from other T cells by their immediate responsiveness to microbes. We previously demonstrated that the primary target for Vgamma9/Vdelta2 T cells is (E)-4-hydroxy-3-methyl-but-2-enyl pyrophosphate (HMB-PP), an essential metabolite produced by a large range of pathogens. Here we(More)
Human blood Vγ9/Vδ2 T cells, monocytes and neutrophils share a responsiveness toward inflammatory chemokines and are rapidly recruited to sites of infection. Studying their interaction in vitro and relating these findings to in vivo observations in patients may therefore provide crucial insight into inflammatory events. Our present data demonstrate that(More)
We address the use ofpictographic representations in an entertainment type , domestic situation of use. In a small-scale experiment 20 sub.jects worked with two versions of a TV-guide simulation: one mainly pictographically-based, one mainly text-based. They were asked for their impressions as well as requested to f'ulfil a series of tasks covering the(More)
BACKGROUND We examined the prevalence of acute kidney injury (AKI) risk factors in the emergency medical unit, generated a modified risk assessment tool and tested its ability to predict AKI. METHODS A total of 1196 patients admitted to medical admission units were assessed for patient-associated AKI risk factors. Subsequently, 898 patients were assessed(More)
Human blood Vc9/Vd2 T cells, monocytes and neutrophils share a responsiveness toward inflammatory chemokines and are rapidly recruited to sites of infection.

BACKGROUND The incidence of chronic kidney disease (CKD) is rising and is likely to continue to do so for the foreseeable future, with the fastest growth seen among adults ≥75 years of age. Elderly patients with advanced CKD are likely to have a higher burden of comorbidity and frailty, both of which may influence their disease outcome. For these patients,(More)
The antimicrobial responsiveness and function of unconventional human T cells are poorly understood, with only limited access to relevant specimens from sites of infection. Peritonitis is a common and serious complication in individuals with end-stage kidney disease receiving peritoneal dialysis. By analyzing local and systemic immune responses in(More)
BACKGROUND Few studies have evaluated the prevalence of severe hyperkalaemia in unselected patient populations. We identified all episodes of severe hyperkalaemia occurring in 1 year, and described patient demographics, clinical response and outcome. We also assessed junior doctor knowledge of its causes and significance. MATERIALS AND METHODS A(More)
