Seroconversion Among Staff at a Large Acute Care Hospital in Denmark During the COVID-19 Pandemic
The aim of this study is to apply serology testing methods for SARS-CoV2 antibodies in samples collected from HCWs in an acute hospital. This will enable the identification of those who are protected and non-infectious for SARS-CoV2 and those who are seronegative and therefore potentially susceptible and infectious on patient …

Natural History Study of Children and Adults With Neuroendocrine Neoplasms (NEN)s
Background Neuroendocrine neoplasms (NENs) are rare tumors that originate in neuroendocrine cells. NENs can affect almost any part of the body. People with low-grade tumors can live many years. But high-grade tumors can be very aggressive. Researchers want to learn more about this type of cancer. This may help them …

Radiomics-based Artificial Intelligence System to Predict Neoadjuvant Treatment Response in Rectal Cancer
In this study, investigators utilize a radiomics prediction model to predict the tumor response to neoadjuvant chemoradiotherapy (nCRT) before the nCRT is administered for patients with locally advanced rectal cancer (LARC). Previously, the radiomics prediction model has been constructed based on the radiomics features extracted from pretreatment Magnetic Resonance Imaging …

RadioPathomics Artificial Intelligence Model to Predict nCRT Response in Locally Advanced Rectal Cancer
In this study, investigators utilize a radiopathomics integrated Artificial Intelligence (AI) supportive system to predict tumor response to neoadjuvant chemoradiotherapy (nCRT) before its administration for patients with locally advanced rectal cancer (LARC). By the system, whether the participants achieve the pathologic complete response (pCR) will be identified based on the …
