Continuous Temperature Monitoring (CTM) for Cytokine Release Syndrome (CRS), an Immune-Related Adverse Event

Background: Drugs or cell therapies to treat cancer can sometimes cause cytokine release syndrome (CRS). That is, the body makes too many cytokines after treatment. Cytokines are proteins that play a role in the immune system. CRS can cause fever, chills, fatigue, low blood pressure, or breathing problems. Researchers want to know if continuously monitoring a person s body temperature can help reduce the chance of getting serious CRS. Objective: To learn if an approved patch called TempTraq can detect fever before serious CRS develops. Eligibility: People aged 18 years and older with cancer who are staying at the NIH clinic for treatment with drugs or cell therapies. Design: Participants will receive TempTraq patches and a special NIH tablet. The TempTraq is a small patch applied to clean, dry skin under the arm. It continually monitors body temperature and sends the data to an application on the tablet. Participants will wear the patch most of the time they are admitted to the hospital. They could wear it for up to 15 days. The patch monitoring does not replace regular temperature checks, all participants will still have have their regular temperature checks as part of their treatment plan. Participants may also opt to use VitalTraq, another application on the tablet. They will hold the screen up to their face for about 1 minute. VitalTraq uses the camera in the tablet to measure blood pressure, heart rate, and breathing. They will do this once per day while they are in the clinic; they may do it more often if they have a fever or feel unwell. Blood may be drawn for research. Participants will be asked about their experience within 1 week after TempTraq is removed. Participants who choose to use the patch, complete its use, and return at a later date for another treatment or study, may be able to re-enroll to have the patch used again.

Comparison of the Effects of Oral Hygiene Regimens on Clinical, Immunomodulatory, and Microbial Outcomes and Oral Tolerance in People With Gingivitis

This study is a six-week, double-blind, randomized, parallel-group controlled clinical study. The objective of this study is to evaluate the changes to the oral microbiome, inflammatory mediators, gingival health indices and to assess oral tolerance after 4 weeks of twice daily use of differing oral hygiene regimens including mouthwash compared to a control group. A follow-up assessment will be completed 2 weeks after cessation of treatments.

The Effect of Smoking on Peri-implantitis

the primary aim of this project is to evaluate the microbiological and inflammatory effect of smoking status and smoking severity on periimplantitis lesions. The secondary aim is to compare the effect of smoking on periimplantitis and periodontal microbiota and inflammation in the same individuals. There will include 96 patients, equally divided into four groups: Smokers with peri-implantitis (n=24), non-smoker individuals with peri-implantitis (n=24), smokers with healthy peri-implant tissues (n=24), non-smoker individuals with healthy peri-implant tissues (n=24). Microbiological and biochemical analyses will be performed on the samples taken.

Impact of Sarcopenia on Dyspnea in Patients With Asthma

Dyspnea in asthma, is mainly due to airway obstruction but can be caused by several alternative diagnoses. The impact of sarcopenia on dyspnea in patients with asthma is unknown. Sarcopenic asthma had a reduced physical activity and is associated with airway obstruction compared to non-sarcopenic asthma. In patients with obstructive pulmonary disease, sarcopenia is associated with shallow breathing and diverse sensory and affective components of exertional dyspnea . The morbidity of sarcopenia is also increased by systemic inflammation and the production of inflammatory cytokines as found in inflammatory airway obstruction. The investigators will investigate the prevalence and impact of sarcopenia in asthmatics patients. This will enable to better manage sarcopenia in asthmatic patients, understand its origins and personalize treatment.

Comparison of Cytokines Profile in Aqueous Humor and Tear Before and After UCP Treatment

Glaucoma is the leading cause of irreversible vision loss in people aged 50 years and older worldwide, second only to cataracts. Ultrasound Cyclo Plasty was first proposed as a new minimally invasive technique in the 1980 s. In recent years, many clinical studies at home and abroad have confirmed the effectiveness, safety and repeatability of UCP. The ciliary body is the target organ of UCP, and the range and accuracy of intraoperative destruction of the ciliary body are the key factors affecting the success or failure of the operation. The production of aqueous humor is closely related to the ciliary body. The dynamic balance of its production and discharge can affect IOP, and its content can directly reflect the intraocular environment. Besides,tears are easy to collect and can be used for follow-up. Previous studies have shown that various proteins in aqueous humor or tear can provide a basis for the pathophysiological changes of glaucoma, and can also be a potential biomarker for predicting the success of anti-glaucoma surgery. At present, UCP related research focuses on its effectiveness and safety, mainly reflected in three aspects : postoperative intraocular pressure, number of anti-glaucoma drugs and complications, and lack of relevant indicators that directly reflect postoperative intraocular environment changes. The purpose of this study was to reveal the changes of cytokines in aqueous humor after UCP in patients with primary glaucoma, to analyze the possible causes of these factors, and to speculate the effect of their interaction on the surgical effect, in order to increase the predictability of UCP procedure.
