Palliative Radiation Treatment in Patients Managed With Advanced/Interventional Pain Therapy such as Pump-delivered Continuous Opioids.

Background/aim: The study aim was to analyze the feasibility and efficacy of palliative radiotherapy in patients receiving advanced/interventional pain therapy, such as epidural or spinal anesthesia or subcutaneous pump delivery of opioids. Endpoints such as pain relief, treatment in the last month of life and survival were evaluated.

Patients And Methods: Different baseline parameters including but not limited to age and Eastern Cooperative Oncology Group performance status (ECOG PS) were assessed.

Survival of rapidly fluctuating natural low winter temperatures by High Arctic soil invertebrates.

The extreme polar environment creates challenges for its resident invertebrate communities and the stress tolerance of some of these animals has been examined over many years. However, although it is well appreciated that standard air temperature records often fail to describe accurately conditions experienced at microhabitat level, few studies have explicitly set out to link field conditions experienced by natural multispecies communities with the more detailed laboratory ecophysiological studies of a small number of 'representative' species. This is particularly the case during winter, when snow cover may insulate terrestrial habitats from extreme air temperature fluctuations.
