Magnetic hyperthermia has been rapidly developed as a potential cancer treatment in recent years. Artificially induced hyperthermia close to a tumor can raise the temperature to 45°C causing tumor cell death. Herein, we introduce a novel method for rapid preparation of anti-cancer magnetocaloric PCL/Fe3 O4 mats capable of high-performance hyperthermia using E-jet 3D printing technology. Read More

The future of nanomedicines in oncology requires leveraging more than just the passive drug accumulation in tumors through the enhanced permeability and retention effect. Promising results combining mild hyperthermia (HT) with lyso-thermosensitive liposomal doxorubicin (LTSL-DOX) has led to improved drug delivery and potent antitumor effects in pre-clinical studies. The ultimate patient benefit from these treatments can only be realized when robust methods of HT can be achieved clinically. Read More

Hyperthermia is an uncontrolled elevation of body temperature exceeding the body's ability to dissipate heat. Hyperthermia can result in dangerously high core temperatures and can rapidly become fatal. Common causes include heat stroke, malignant hyperthermia, serotonin syndrome, neuroleptic syndrome, a few endocrine emergencies as well as numerous intoxications. Read More

New guidelines for the resuscitation of newborns confirm that therapeutic hypothermia should be the standard method of treatment offered to neonates with acute perinatal hypoxia. The quality of care which an asphyxiated newborn receives during and immediately after resuscitation, as well as the mode of preparation for transport, can have a significant impact on improving the outcome, but it can also result in the deterioration of neonates treated with hypothermia.

There are many approaches to and opportunities for implementing temperature modulation in critically ill patients, but barriers also exist. Conceptually, the process of cooling is rather straightforward; however, targeted temperature management is anything but simplistic. The need for a collaborative approach (physicians champions, nursing support, respiratory therapists, pharmacists, laboratory personnel, and supply chain representatives) to address definitions of normothermia and fever, patient inclusion/exclusion criteria for therapy based on underlying neurorelated pathologies, determination of methods of induction/maintenance, monitoring required, education planning, and strategies to minimize potential complications are warranted.
