11 Clinical Trials for Various Conditions
This study is intended to calculate the core body temperature in patients who are having a Cesarean Section (C/S) and are kept warm with an Upper Body Forced Air Warming device (Bair Hugger) or underbody forced air warmer. These warming devices are approved and are a required item in many if not all surgical procedures. They are used daily throughout the hospital. The research question is: Where is the best place to position the warming blanket in pregnant mothers undergoing Cesarean section delivery. The researchers hope to compare post - operative core body temperatures in patients getting an Upper Body forced air device versus those getting an Underbody Body forced air warming device.
This study evaluates the safety and usability of a continuous temperature sensor for women. Data will compare the date of ovulation identified by the continuous temperature sensor to that of transvaginal ultrasound and serum progesterone levels. Subjects will also compare sensor results to once-daily oral temperatures and urine luteinizing hormone (LH) status.
The primary objective of the proposed study is to determine the use of a wireless method to monitor and record core body temperature during a Whole Body Hyperthermia treatment, compared to an indwelling rectal thermometer. This protocol is intended to study the differences between a rectal temperature probe and an approved wireless and indigestible thermometer during a WBH session. The current standard in monitoring core body temperature is the usage of an indwelling rectal thermometer. Many patients and potential study subjects, however, decline receiving the treatment, due to the discomfort of using this measuring method and a wireless measuring device would open the possibility for those patients to receive a treatment. The primary endpoint for example of a treatment for MDD is currently defined with reaching a rectal temperature of 38.5 C. However, due to the proximity of the probe to the body's surface, the core body temperature will vary from the rectal temperature and the comparison between the two methods with a validation of the wireless device is necessary. The investigators will monitor subject's physiological outcome from a single Whole Body Hyperthermia treatment in an open fashion (no placebo/control condition). This study will include safety assessments 7 days several days prior to or same day as the WBH, and include follow-up assessments 1 day and 1 week later.
Whole-body hyperthermia (WBH) to an internal temperature of 38.5 C (101.3 F) using an infrared heating device has been associated with significant reductions in clinical depression. This prior work utilized a WBH medical device that is manufactured in Germany, is not FDA approved, and is not widely available. The goal of this initial pilot project is to ascertain whether an infrared sauna, the Curve Sauna Dome, which is readily accessible (i.e., can be purchased by consumers in the US) can be used to conduct WBH that achieves an internal body temperature of of 101.3 F in healthy volunteers.
The purpose of the study is to evaluate effects of high rebound mattress toppers (i.e., airweave®) on sleep and sleep-related symptoms. The study will compare effects of use of high rebound mattress toppers versus use of low rebound mattress toppers on sleep and sleep related symptoms and core body temperature during diagnostic sleep studies.
Alzheimer's disease (AD) is a common neurodegenerative disease characterized by the accumulation of amyloid plaques and neurofibrillary tangles. Current consensus is that the AD pathological process begins decades before clinical symptoms occur. This long "preclinical" phase of AD might first become detectable in middle-age as deposits of hyperphosphorylated tau (P-tau) in the transentorhinal cortex and subcortical nuclei such as the locus coeruleus (LC) and the nucleus basalis of Meynert. There is strong preliminary evidence showing that cerebrospinal fluid (CSF) levels of orexin-A (OxA) are associated with increased P-tau (r=.52, p\<.01) and total-tau (T-tau) (r=.42, p\<.01) in cognitively normal older adults (mean age: 69.6±8.6 years). This study poses that onset of tauopathy in the LC results in down regulation of orexin receptors, leading to a homeostatic increase of OxA production by the hypothalamus, which results in changes in core body temperature (CBT) and sleep disruption that cause further neurodegeneration. This hypothesis will be tested by demonstrating that increases in CSF P-tau are associated in vivo with tau PET uptake, and that tau binding in the LC is associated with increases in CSF OxA (Aim 1); and second, by analyzing the downstream consequences of increased central nervous system (CNS) OxA on sleep architecture and CBT (Aim 2). To test these hypotheses, 19 older adults (age 55-75) balanced by sex, will first perform a full clinical evaluation and PET-MRI where Tau burden will be analyzed by PET-MR using 18F-MK6240 (visits 1-2). Subjects will later undergo 7 days of actigraphy followed by nocturnal polysomnography (NPSG) for 2 consecutive nights (N1-2) during which we will measure CBT (visits 3-4). A morning lumbar puncture (LP) will be performed after N2 to obtain CSF.
This is a descriptive, nonrandomized, noninvasive, single-group, single-center pilot study of a Core Cooling System (CCS) device for reducing core body temperature in ICU patients at University Medical Center Brackenridge (UMCB) and Seton Medical Center Austin (SMCA). The proposed research on human subjects will provide data that will be used to improve a specialized human heat transfer technique/device. By stimulating specialized blood vessels (arteriovenous anastomoses) AVAs in the palm of the hand, it is possible to greatly increase local blood flow and thus greatly increase the potential for effective heat transfer between the environment and body. The hypothesis of this trial is that the Core Cooling System (CCS) will prove to be a practical, safe, and effective method to raise or lower body temperature in critically ill patients.
This study aims to determine the effects of transcutaneous spinal cord stimulation to increase blood pressure and use that device to increase exercise endurance time and heart rate recovery during arm cycle ergometry. In addition, the investigators will see if the stimulation helps regulate body temperature when in a cool environment.
The purpose of this trial is the generation of clinical data required for a 510(k) submission to the FDA.
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.
This study is investigating the efficacy of CORE™ devices in calculating core body temperature in athletes under varying environmental conditions.
