Filter by:Cesarean section is surging worldwide. For an extended period of surgical practice, the scalpel has been well-known as a gold-standard tool for making surgical incisions. The diathermy, electrocautery, is a substitute.
An epidemic of chronic kidney disease is occurring in laborers who undertake physical work outdoors in hot conditions. The reason for this is largely unknown, but may be related to kidney dysfunction caused by increases in body temperature and dehydration that elicit oxidative stress and inflammation in the renal tubules. The purpose of this study is to determine whether hydration status modifies the development of renal oxidative stress and inflammation.
Persons with higher levels of spinal cord injury (above the 6th thoracic vertebrae: Hi-SCI) are unable to maintain their core body temperature (Tcore) within the normal range (97.5-99.7 °F) when exposed to warm environments. Even limited exposure to warm temperatures can cause hyperthermia (Tcore 100.4°F) in Hi-SCI. Mild hyperthermia causes discomfort and impaired thinking, but if unchecked, can lead to permanent damage to the brain, multiple body organ failure, and death. Warm seasonal temperatures have an adverse effect on personal comfort and the ability to participate in daily social activities in persons with Hi-SCI. Interventions addressing this vulnerability to hyperthermia are limited. A self-regulating "smart" cooling vest designed for persons with Hi-SCI, that can effectively dissipate body heat, is a novel and promising strategy to address this problem. Once the current prototype is further developed and bench-tested, the investigators will test the vest in able-bodied participants for safety and comfort. The investigators will then test the vest in participants with Hi-SCI for efficacy. The aim for the cooling vest to minimize the expected increase of 1.1°F in Tcore by at least 50 percent and increase thermal comfort, during a controlled exposure to heat (95°F). If successful, the vest will provide a promising intervention to decrease the adverse impact of warm temperatures on comfort, quality of life, and participation in societal functions for Veterans with Hi-SCI during the warmer seasons.
Hyperthermic Intraperitoneal Chemotherapy (HIPEC) is a well-established alternative for patients with peritoneal surface malignancies. Although HIPEC has a predetermined protocol to manage body temperature, the resultant bladder and core-body temperatures are highly variable and unstable in clinical practice. Such results highlight an incomplete understanding of the thermodynamic processes during HIPEC in humans. Previous clinical and animal investigations have studied abdominal hyperthermia, but a full human model incorporating patient variables, heat delivery, and the impact of the circulatory system and anesthesia in HIPEC has not been established. This project seeks to develop and validate a computational thermodynamic model using prospective real-world data from humans undergoing HIPEC surgery. It is hypothesized that by incorporating patient, anesthetic, and perfusion-related variables in a thermodynamic model, the temperatures inside and outside the abdomen during HIPEC can be predicted.
This is a single-center study design, and 30 patients will be enrolled. Eligible patients will receive docetaxel at different dose levels according to the trial schedule.All the enrolled patients were treated with docetaxel during the first HIPEC treatment and cisplatin during the second HIPEC treatment at 43℃ for 1 hour.The dose of docetaxel for patients in the next group was determined according to the incidence of dose-limiting toxicity (DLT) of the previous docetaxel dose level. Finally, the maximum tolerated dose (MTD) of docetaxel for HIPEC was calculated according to the incidence of dose-limiting toxicity.
This study intends to target patients who underwent surgery under general anesthesia during the study period and developed malignant hyperthermia during or after surgery. Therefore, the total sample size was estimated to be about 50 people based on the past incidence of this rare disease. Every year, about 20 patients and their families who developed malignant hyperthermia during or after surgery will participate in this nationwide study (estimated by the current incidence of malignant hyperthermia), and about 1-5 patients will be admitted to Peking University Third Hospital participate in this research. Relevant specimens were collected from malignant hyperthermia (MH) patients and their family members for genetic analysis to determine the mutation of MH-related pathogenic gene loci.
This study will include 20 healthy subjects with intact skin on their lower legs that meet inclusion criteria. Participants will serve as their own control, by heating one leg and not the other. The radiofrequency device consists of a 4 by 6 inch heating pad connected to a temperature controller. Subjects will receive weekly treatments for 4 weeks, and will be re-evaluated 4 weeks after the last treatment to assess any tissue changes that continue after the treatments have concluded.
Analysis of the efficacy and the compatibility of deep regional hyperthermia in combination with radiotherapy and chemoradiotherapy in bladder cancer
The goal of this study is to examine how whole-body hyperthermia affects the thermoinflammatory profile, which includes the combined immune and heat shock response, in patients with depression and whether these changes correlate with decreased depression in individuals with Major Depressive Disorder.
The purpose of the study is to compare physiological responses to two hours of work adhering to two variations of a work-to-rest ratio in a hot environment.
