The purpose of this study is to assess the performance of the subcutaneous glucose sensor over an extended sensor life. The sensor is currently approved for 3 days of use and this study will examine sensor safety and accuracy when used for six days. This study will also test sensor safety and accuracy when inserted in an alternate body location (buttock area in addition to abdomen area). The study hypothesis is that the sensor performance will not greatly diminish when used for...
Sudden unexpected death in epilepsy patients (SUDEP) is devastating outcome for some patients with epilepsy. It ranks second only to stroke among neurological diseases in years of potential life lost. Patho-mechanisms of SUDEP remain not well understood, however peri-ictal respiratory dysfunction likely plays an important role in many cases. Literature supports a critical role for the serotonergic system in central control of ventilation. Serotonin neurons in the raphe nuclei ...
The impressive clinical responses obtained with immune checkpoint inhibitors (anti-PD-1/PDL-1, anti-CTLA-4) indicate that the presence of preexisting antitumor immune response might be required for their efficacy and highlight the critical role of antitumor T cell immunity. Recent progresses on the field of tumor immunology underline the critical role of CD4 helper 1 T lymphocyte (TH1) in the control of innate and adaptive anticancer immunity. Therefore, monitoring tumor...
The purpose of this study is to assess performance of a new subcutaneous glucose sensor over a seven day sensor life when used with currently marketed Medtronic Diabetes devices. In addition performance of the new sensor will be calculated for use of the new sensor with proposed new devices using new calibration algorithms.
The investigators aim to test whether beta-endorphin, a substance our bodies make in response to painful and stressful stimuli, plays a causative role in radiation-induced fatigue that cancer patients receiving radiation therapy commonly experience. If this is so, the investigators' hope is to direct efforts at treating radiation-induced fatigue using agents that block the action of beta-endorphin with the aim of improving quality of life for patients undergoing radiation thera...
Increasing evidence suggests that immune responses might be a determining factor in lung cancer tumor progression. The impressive clinical responses obtained with immune checkpoint inhibitors (anti-PD-1/PDL-1, anti-CTLA-4) indicate that the presence of preexisting antitumor immune response is required for their efficacy and highlight the critical role of antitumor T cell immunity. Recent progress on the fields of tumor immunology underlines the critical role of CD4 helpe...
An open interventional data collection study in order to build a database to close the loop between glucose sensor and insulin pump. In this study, the researchers will evaluate the delay time of glucose sensing at the subcutaneous tissue and will test several real-time sensor calibration algorithms towards a close loop. The following data will be analysed: 1. reaction time of the continuous subcutaneous glucose sensor to increase in blood glucose levels in respo...
It is difficult to assess pain and agitation in the NICU population because for a multitude of reasons including the pre-verbal nature of the patient population, the atypical pain response of premature infants, and the use of muscle relaxing medications that exclude motor response in pain assessments. Current assessment tools are based on physical exam and vital signs. The investigators propose to study the role of EEG and palmar conductance (PD) as additional tools in the asse...
As a counterregulatory hormone for insulin, glucagon plays a critical role in maintaining glucose homeostasis in vivo. It is well known that intramuscular glucagon administration stimulates growth hormone (GH), adrenocorticotropic hormone (ACTH) and cortisol release in humans. Recently, it has been shown that glucagon induces a remarkable decrease in ghrelin levels. The mechanisms underlying this effect are unclear and the role of changes in glucose, insulin, glucagon-like pept...
The purpose of this study was to conduct a side by side comparison of the accuracy of respiratory rate (RR) between our Rainbow Acoustic Monitoring (RAM) small sensor and the Revision D sensor in healthy volunteers. Our hypothesis was that the RAM small sensor would have comparable or a better performance than the revision D sensor.
Unexpected cardiac arrest involves approximately 0.5 to 5% of patients admitted in Intensive Care Unit (ICU). Even if they have a technical environment conducive to prompt diagnosis and prompt treatment, patients hospitalized in ICU suffer from chronic illnesses and organ failure(s) that obscure the prognosis of cardiac arrest. Although extra cardiac arrhythmias or intra-hospital arrests are the subject of numerous publications, few studies specifically focus on unexpected card...
For family members of chronically critically ill (CCI) patients, an ICU admission marks a significant milestone in the patient's illness trajectory that highlights the onset of end of-life issues and an abrupt need for family members to assume the caregiver role for the first time. Assuming the caregiver role can have devastating and longstanding health consequences for family members, which can impair their ability to sustain caregiving behaviors for a CCI patient. The unrelen...
TACE possibly plays a significant role in contributing to a subgroup of surviving residual tumor tissue which is characterized by more aggressive biology. This explains the strong scientific rationale for exploring the role of anti-angiogenic therapy such as sorafenib to remedy and strengthen the therapeutic efficacy of TACE to combat liver cancers. Sorafenib plays a prominent auxiliary role by further suppressing the tumor growth and prolonging the time to recurrence and progr...
This trial seeks to demonstrate clinical accuracy and safety of the integrated V-Sensor when used by the general, healthy adult population interested in measuring their vital signs outside of the clinical setting.
Malignant ascites is a severe complication of many types of human cancer. Animal and clinical analyses have shown that angiogenesis plays a critical role in the formation of malignant ascites. Therefore, drugs such as apatinib that target angiogenesis may control the development of malignant ascites. The study is to evaluate the efficacy and safety of apatinib in patients with refractory malignant ascites.
The purpose of this study is to support the use of the Enlite 3 sensor in arm and thigh in subjects age 14 - 75 years and provide additional characterization of the Enlite 3 sensor performance in arm in subjects age 14 - 75 years.
The Double Sensor examined in this trial was developed by Dräger Company and is a novel non- invasive device for assessing core body temperature. In a preliminary research investigators have conducted the Double Sensor was found promising for potential use of physiological heat stress early detection. This follow-up experiment was designed to validate the data during high and changing body core temperatures and to examine the Double Sensor performance while integrated into a h...
The purpose of this study is to assess accuracy and reliability of the SPIDIMAN CGM sensor system with regard to values as measured by Super GL and compare these results with similar evaluations of the Medtronic MiniMed 640G system, the Abbott FreeStyle Libre Flash Sensor and the DexCom G4 Platinum Sensor in patients with type 1 Diabetes.
This study evaluates the addition of a wearable real-time UV sensor in the prevention of skin cancer development in kidney-transplant patients. Half of participants will receive a wearable ultraviolet sensor with standard-of-care counseling while the other half will receive only sun protection counseling.
The Phenomenon of Tumor Hypoxia Many solid tumors are relatively resistant to treatment with ionizing radiation and certain chemotherapeutic agents such as anthracyclines that are affected adversely by acidic pH. These effects have primarily been attributed to the presence of hypoxic cells within the tumor. The relevance of hypoxia with respect to failure of radiotherapy to cure certain malignancies has had a chequered history. However, in recent years the evidence that hypo...

The goal of this clinical research study is to learn about a new minimally invasive glucose monitoring device called Fluorescence Affinity Sensor (FAS). In this study, the FAS will be used to determine its effectiveness for glucose monitoring. Researchers want to find out how the device performs at two different body sites (forearm and abdomen) over 4 hours. The safety and comfort level of the device will also be studied.
