Precooling, Exertional Heatstroke Risk Factors, and Postexercise Cooling Rates.

Aerosp Med Hum Perform 2019 Jan;90(1):12-17

Precooling (PC) before exercise may help prevent severe hyperthermia and exertional heatstroke (EHS). Before clinicians can advocate PC as an EHS prevention strategy, it must effectively mitigate factors associated with EHS development while not lessening the effectiveness of EHS treatment. Therefore, this study determined if PC affected rectal temperature (T), body heat storage, heart rate (HR), ratings of perceived exertion (RPE), thermal sensation, sweat rate, and postexercise cold-water immersion (CWI) T cooling rates.

Effectiveness of Two Targeted Temperature Management Methods After Pediatric Postcardiac Arrest: A Multicenter International Study.

Pediatr Crit Care Med 2018 Dec 6. Epub 2018 Dec 6.

PICU, Hospital General Universitario Gregorio Marañon, Universidad Complutense de Madrid, Maternal and Child Health and Development Network (Red SAMID), Madrid, Spain.

Objectives: It is currently recommended that after return of spontaneous circulation following cardiac arrest, fever should be prevented using TTM through a servo-controlled system. This technology is not yet available in many global settings, where manual physical measures without servo-control is the only option. Our aim was to compare feasibility, safety and quality assurance of servo-controlled system versus no servo-controlled system cooling, TTM protocols for cooling, maintenance and rewarming following return of spontaneous circulation after cardiac arrest in children.

MR thermometry-guided ultrasound hyperthermia of user-defined regions using the ExAblate prostate ablation array.

J Ther Ultrasound 2018 13;6. Epub 2018 Aug 13.

1Department of Radiology and Biomedical Imaging, University of California San Francisco, 185 Berry Street, Suite 350, Box 0946, San Francisco, CA 94107 USA.

Background: Hyperthermia therapy (HT) has shown to be an effective adjuvant to radiation, chemotherapy, and immunotherapy. In order to be safe and effective, delivery of HT requires maintenance of target tissue temperature within a narrow range (40-44 °C) for 30-60 min, which necessitates conformal heat delivery and accurate temperature monitoring. The goal of this project was to develop an MR thermometry-guided hyperthermia delivery platform based upon the ExAblate prostate array that would achieve uniform stable heating over large volumes within the prostate, while allowing the user to precisely control the power deposition patterns and shape of the region of treatment (ROT).

Core and skin temperature influences on the surface electromyographic responses to an isometric force and position task.

PLoS One 2018 29;13(3):e0195219. Epub 2018 Mar 29.

Department of Kinesiology, Brock University, St. Catharines, Ontario, Canada.

The large body of work demonstrating hyperthermic impairment of neuromuscular function has utilized maximal isometric contractions, but extrapolating these findings to whole-body exercise and submaximal, dynamic contractions may be problematic. We isolated and compared core and skin temperature influences on an isometric force task versus a position task requiring dynamic maintenance of joint angle. Surface electromyography (sEMG) was measured on the flexor carpi radialis at 60% of baseline maximal voluntary contraction while either pushing against a rigid restraint (force task) or while maintaining a constant wrist angle and supporting an equivalent inertial load (position task).

In Patients with Severe Peripheral Arterial Disease, Revascularization-Induced Improvement in Lower Extremity Ischemia Can Be Detected by Laser Speckle Contrast Imaging of the Fluctuation in Blood Perfusion after Local Heating.

Ann Vasc Surg 2018 Apr 5;48:67-74. Epub 2017 Dec 5.

Department of Surgical Specialties, Tokyo Medical and Dental University, Tokyo, Japan.

Background: We previously reported the utility of the perfusion value (PV) fluctuation slope for detecting severe ischemia in the lower limb. Our approach was based on a thermal load test mimicking the well-known physiological reaction termed "cold-induced vasodilation," which is known to occur as a 3-phase phenomenon. The slope parameter quantifies the decrease in PVs accompanying the relative cooling (third phase) following the transient increase in blood flow (second phase) induced by the applied thermal load.

Post-exercise recovery of contractile function and endurance in humans and mice is accelerated by heating and slowed by cooling skeletal muscle.

J Physiol 2017 12 25;595(24):7413-7426. Epub 2017 Oct 25.

Karolinska Institutet, Stockholm, Sweden.

Key Points: We investigated whether intramuscular temperature affects the acute recovery of exercise performance following fatigue-induced by endurance exercise. Mean power output was better preserved during an all-out arm-cycling exercise following a 2 h recovery period in which the upper arms were warmed to an intramuscular temperature of ̴ 38°C than when they were cooled to as low as 15°C, which suggested that recovery of exercise performance in humans is dependent on muscle temperature. Mechanisms underlying the temperature-dependent effect on recovery were studied in intact single mouse muscle fibres where we found that recovery of submaximal force and restoration of fatigue resistance was worsened by cooling (16-26°C) and improved by heating (36°C).

Focused Ultrasound Hyperthermia Mediated Drug Delivery Using Thermosensitive Liposomes and Visualized With Two-Photon Microscopy.

Theranostics 2017 7;7(10):2718-2731. Epub 2017 Jul 7.

Physical Sciences Platform, Sunnybrook Research Institute, Toronto, ON, Canada.

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

[Treatment of hyperthermia].

Ugeskr Laeger 2017 Jul;179(30)

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

Determination of Dielectric Properties of Cryoprotective Agent Solutions with a Resonant Cavity for the Electromagnetic Rewarming in Cryopreservation.

Biopreserv Biobank 2017 Oct 7;15(5):404-409. Epub 2017 Aug 7.

1 Department of Mechanical Engineering, University of Washington , Seattle, Washington.

In the rewarming process during cryopreservation, preventing ice recrystallization and thermal stress is important, especially for large tissues and organs. Uniform and rapid heating is essential in ameliorating the problem and maintaining the viability of cryopreserved biological samples. Currently, the most promising method is heating by application of electromagnetic (EM) waves, the effectiveness of which is dependent on the dielectric properties (DP) of the cryopreserved materials.
