12 Clinical Trials for Various Conditions
Long-wavelength infrared (IR) detectors have a more than 20-year history in medical thermometry and have been used widely for febrile screening. However, over the past year and a half, public health entities, medical professionals, and the general public have begun to question the claimed accuracy of non-contact body thermometry. The standard assessment of a device's performance relies on clinical testing with febrile individuals, yet this practice may have inadvertently allowed the approval of IR systems that are unable to detect moderate fevers. The ability to test device performance without relying on febrile test participants would have important ramifications for public health, especially if this test discovered undisclosed differences in accuracy in widely used devices. The aim is to examine the effect of the local environment and the physiology of the human body on the relationship between core body temperature and inner canthi (region near tear duct) skin temperature measured using non-contact thermal imaging and to use of this relationship to test actual device performance at detecting simulated elevated temperatures, without requiring volunteers having actual elevated temperatures. The overall goal of this research study is to validate and improve the science of non-contact core body temperature measurement.
Nasopharyngeal and deep tissue temperatures will be measured simultaneously during surgery and compared for agreement. The hypothesis of this trial is that deep tissue temperature as measured by zero-heat-flux thermometry will agree with nasopharyngeal temperatures during surgery.
The purpose of this trial is the generation of clinical data required for a 510(k) submission to the FDA.
This research study aims to better understand how the plantar temperature data collected by the Podimetrics RTM System corresponds to physical activity level in subjects.
The American Heart Association (AHA) recommends cooling (inducing mild hypothermia) patients who were resuscitated following cardiac arrest but who remained comatose. Induced mild hypothermia is now the standard of care for post-resuscitation patients in the intensive care unit (ICU) setting. The use of cooling has recently moved to pre-hospital and emergency department (ED) application as more current studies show that early initiation of cooling significantly improves neurologic outcomes and survival rates instead of waiting until the patient arrives in the ICU to initiate cooling. In the pre-hospital setting chilled saline (4°C) and packing the body in ice have been the primary methods to initiate induced mild hypothermia The Excel Cryo Cooling System is a non-invasive cervical collar (C-collar) that provides cooling to the carotid arteries, the main blood supply to the brain, and allows for the rapid initiation of selective cerebral cooling. The investigators are planning to use MRI-thermometry to see how quickly the Excel Cryo Cooling Collar can drop brain temperature when applied by itself. Healthy volunteers will be used for this study to provide important temperature data on the effectiveness of the Excel Cryo Cooling System. The investigators will be able to use the data from this project to further the current clinical research in induced mild hypothermia after cardiac arrest.
Foot ulcers develop in diabetics with neuropathy because of cumulative injury over the course of several days. These patients do not feel pain, and do not recognize their foot is being injured until a wound develops. Areas about to ulcerate become inflamed and "hot spots" can be identified. This study's purpose is to evaluate the effectiveness of a home infrared temperature probe designed to forewarn patients that an area on the foot is inflamed so they can take preventive measures. The study will evaluate the incidence of diabetic foot ulcers among high-risk patients, evaluate the cost of home temperature monitoring compared to standard therapy, and evaluate patient satisfaction. 180 diabetics at high-risk of having foot complications will be randomized into 3 treatment arms: 1) standard therapy consisting of regular foot care; 2) standard therapy plus recording of a structured foot evaluation using a hand mirror; and 3) standard therapy plus infrared home temperature assessment to identify "hot spots." Device patients will measure temperatures at 6 sites on the foot each day. When temperatures are elevated \>4°F patients will contact the research nurse and decrease activity. The primary study outcome will be incident foot ulcers and Charcot fractures.
Foot ulcers remain the most common reason for hospital admission among veterans with diabetes. Healing and preventing these wounds should be a high priority for clinicians treating these high-risk patients. Previous work by the investigators has suggested that diabetic foot ulcers are preceded by inflammation, which can potentially be detected with a thermometer.
RATIONALE: Hyperthermia therapy kills tumor cells by heating them to several degrees above body temperature. Using MRI to measure heat may help to determine the effectiveness of hyperthermia therapy. Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs used in chemotherapy, such as ifosfamide and doxorubicin, work in different ways to stop tumor cells from dividing so they stop growing or die. Combining hyperthermia with radiation therapy and chemotherapy before surgery may kill more tumor cells and shrink the tumor so that it can be removed. PURPOSE: This phase I/II trial is studying the side effects of hyperthermia when given together with radiation therapy and optional chemotherapy and to see how well they work in treating patients who are undergoing surgery for soft tissue sarcoma of the limbs.
Preterm infants will have their body temperature measured by three different devices in order to evaluate whether the newest device, a temporal artery scanning thermometer, is accurate for patients in the preterm period.
Primary study objective is to test the accuracy of the Genius 2 tympanic thermometer and the Exergen TAT-5000(TM) temporal artery thermometer as compared with serial perioperative core temperature measurements obtained in cardiac surgical patients during cardiopulmonary bypass. Study hypothesis: The Genius 2 thermometer will display greater precision and accuracy than the Exergen TAT-5000 thermometer when compared to core body temperature in patients undergoing CABG surgery.
Despite some controversial results, many patients and animal studies have suggested significant benefit of using hypothermia treatment in stroke patient population. However, certain questions for how to applying this therapy properly such as when to start, what is the optimal temperature, how long is the duration, and what is the best hypothermia technology that may avoid the complications including focal soft tissue injuries are still remain questioned. In this study, we will utilize the linear relationship of temperature vs. chemical shift in MR Spectroscopy to measure the brain temperatures in normal men.
Body temperature measurement is one of the standard vital sign measurements in newborn babies in order assess their health status. Temperatures are taken on a regular basis throughout the newborn's stay on the well-baby floor. A temperature that is elevated above the normal range for age or depressed below the normal range for age may be a sign of illness in a newborn. There are many methods that may be used to record this temperature. Traditionally, axillary (under the arm) and rectal (in the rectum) sites have been used. Recently, a new method of temperature measurement has become available. Temporal artery thermometers are a non-invasive method to measure the baby's temperature by means of a light that is shone on the forehead that can read your baby's temperature quickly. It is not clear whether this method is accurate in the newborn period. The purpose of this study is to evaluate the accuracy of temporal artery temperature measurement. This will be achieved by observing the axillary measurement, rectal temperature measurement, and temporal artery temperature measurement taken at approximately the same time in each infant. These measurements will be compared to each other to determine if temporal artery thermometry is as reliable a measurement as rectal and / or axillary temperature measurements. We plan to compare Hypothesis: Temporal artery thermometry of the immediate newborn infant is an accurate measurement of temperature in this age group.
