We report on preliminary experiences with deploying a large-scale sensor network (about 100 nodes) for a pilot in precision agriculture. The pilot did not answer the initial research questions, but instead revealed many engineering problems typically overlooked by (computer) scientists evaluating their work by means of simulation. The deployment prompted us(More)
Neuroendocrine tumours account for only 0.5% of all malignancies. The incidence is approximately 2/100,000 with a female preponderance under the age of 50 years due to appendiceal location. The main primary sites are the gastrointestinal tract (62-67%) and the lung (22-27%). Presentation with metastatic disease accounts for 12-22%. In the last decades, the(More)
— The focus of the sensor network community on energy-efficiency has produced a string of novel MAC, routing, and data-aggregation protocols. Their power consumption has mainly been assessed through simulations, i.e. by counting the fraction of time spent in sending, receiving, and computing, and multiplying that by figures taken from data sheets or(More)
BACKGROUND The complement of the cancer mortality to incidence ratio [1-(M/I)] has been suggested as a valid proxy for 5-year relative survival. Whether this suggestion holds true for all types of cancer has not yet been adequately evaluated. METHODS We used publicly available databases of cancer incidence, cancer mortality and relative survival to(More)
Autologous hematopoietic stem cell transplantation (ASCT) is an increasingly accepted treatment for refractory autoimmune diseases. Refractory celiac disease with aberrant T cells (RCD type II) is unresponsive to available therapies and carries a high risk of transition into enteropathy associated T-cell lymphoma (EATL). This study reports on the(More)
PURPOSE Positron emission tomography (PET) with (89)Zr-ibritumomab tiuxetan can be used to monitor biodistribution of (90)Y-ibritumomab tiuxetan as shown in mice. The aim of this study was to assess biodistribution and radiation dosimetry of (90)Y-ibritumomab tiuxetan in humans on the basis of (89)Zr-ibritumomab tiuxetan imaging, to evaluate whether(More)
BACKGROUND The impact of age and adjuvant therapy on contralateral breast cancer (CBC) risk and prognostic significance of CBC were evaluated. PATIENTS AND METHODS In 45,229 surgically treated stage I-IIIA patients diagnosed in the Netherlands between 1989 and 2002 CBC risk was quantified using standardised incidence ratios (SIRs), cumulative incidence(More)
BACKGROUND Diagnosing colorectal cancer (CRC) at an early stage improves survival. To what extent any delay affects outcome once patients are symptomatic is still unclear.Our objectives were to evaluate the association between diagnostic delay and survival in symptomatic patients with early stage CRC and late stage CRC. METHODS Prospective(More)
AIM To evaluate cladribine [2-chlorodeoxyadenosine (2-CdA)] therapy in refractory celiac disease (RCD) II. METHODS An open-label cohort-study of RCD II patients treated with 2-CdA was performed between 2000 and 2010. Survival rate, enteropathy associated T-cell lymphoma (EATL) occurrence, clinical course, and histological and immunological response rates(More)
OBJECTIVES To assess the suitability of the Breast Imaging Reporting and Data System (BI-RADS) as a quality assessment tool in the Dutch breast cancer screening programme. METHODS The data of 93,793 screened women in the Amsterdam screening region (November 2005-July 2006) were reviewed. BI-RADS categories, work-up, age, final diagnosis and final TNM(More)
