COVID-19: a simple statistical model for predicting intensive care unit load in exponential phases of the disease.

One major bottleneck in the ongoing COVID-19 pandemic is the limited number of critical care beds. Due to the dynamic development of infections and the time lag between when patients are infected and when a proportion of them enters an intensive care unit (ICU), the need for future intensive care can easily be underestimated. To infer future ICU load from reported infections, we suggest a simple statistical model that (1) accounts for time lags and (2) allows for making predictions depending on different future growth of infections.

Intensity modulated perioperative HDR brachytherapy for recurrent and/or advanced head and neck metastases.

Recurrent neck metastases following surgery and full dose adjuvant radiotherapy of squamous cell head and neck cancer remain a clinical challenge. After revision neck dissection and chemotherapy re-irradiation dosage is often limited and survival prognosis deteriorates. Here, adjuvant high-dose rate intensity modulated perioperative brachytherapy (HDR IMBT) offers a second full radiation dose with a limited volume of normal tissue radiation in the neck.

Perioperative image-adapted brachytherapy for the treatment of paranasal sinus and nasal cavity malignancies.

Purpose: Sinonasal malignancies are a rare group of cancers often associated with late presentation and poor prognosis. In the past, there was little progress regarding survival rate, and often, multimodal treatment regimens are required. The aim of this study was to evaluate the clinical outcome of perioperative image-adapted brachytherapy (IABT) as part of a multidisciplinary treatment regimen for the therapy of sinonasal cancer.
