[How long are medical oncology patients in The Netherlands willing to travel for their cancer care?] / Hoe lang zijn patiënten bereid te reizen voor medisch-oncologische zorg?

BACKGROUND: The number of people with cancer will increase in the Netherlands. Further concentration and network care is pursued. The aim of this study was to explore how long medical oncology patients are willing to travel for their cancer care. METHOD: A flashmob study into patients' willingness to travel for cancer care was conducted in 65 Dutch hospitals. Patients completed a questionnaire about willingness to travel and any experienced issues with traveling. RESULTS: A total of 4337 medical oncology patients completed the questionnaire. Of the patients, 20% were willing to travel more than 1 hour (one-way) for their current treatment, and more willing to travel for treatment in a hospital more experienced in their specific type of cancer (44% more than 1 hour). Willingness to travel longer was higher among patientsagedv40 years or younger, those with higher education, with better physical functioning and with a rare cancer. Willingness to travel longer was lowest among patients aged 75 or older. Approximately 30% of all patients experienced issues with traveling, especially those with comorbidities or with decreased physical functioning. CONCLUSION: In this flashmob study, 15% of patients were willing to travel up to 30 minutes (one-way) and 44% more than 1 hour for treatment and follow-up in a hospital more experienced in their specific type of cancer. Patients aged 75 years or older were less willing to travel longer. Thirty percent of patients experienced issues with travelling. It is important to take this into account in the future organization of cancer care.

Preconditioning with recombinant high-mobility group box 1 protein protects the kidney against ischemia-reperfusion injury in mice.

A preconditioning effect occurs when exposure to a nonharmful quantity of a mediator of injury provides protection against injury upon subsequent reexposure. High-mobility group box 1 (HMGB1) protein, an endogenous ligand for Toll-like receptor (TLR) 4, is a TLR4-dependent mediator of kidney ischemia-reperfusion injury. Here we determined whether preconditioning with recombinant HMGB1 can block kidney ischemia-reperfusion injury, whether this effect is TLR4 dependent and, if so, how preconditioning downregulates TLR signaling. Wild-type mice pretreated with rHMGB1 before ischemia were protected against kidney ischemia-reperfusion injury, indicated by lower serum creatinine, less tubular damage, less tubulointerstitial neutrophil and macrophage infiltration, and less tubular epithelial cell apoptosis versus control mice. Gene expression of TLR-downstream cytokines and chemokines in ischemia-reperfusion injury kidney were also significantly reduced. While TLR4 and TLR2 knockout mice were protected against kidney ischemia-reperfusion injury, HMGB1 preconditioning provided additional protection to TLR2 but not TLR4 knockout mice. The protective effect of rHMGB1 preconditioning involved Siglec-G upregulation, a negative regulator of HMGB1-mediated TLR4 pathway activation. Thus, preconditioning with rHMGB1 affords significant protection from TLR4-dependent kidney ischemia-reperfusion injury, indicating therapeutic potential.
