Filter by:This is a 6-week ketogenic diet (KD) intervention where participants with rheumatoid arthritis (RA) will follow a KD plan, supervised and monitored by a dietician. Participants will be provided extensive educational and ongoing support on the KD, including personalized coaching with the ability to text a dietitian at any time and expect a response within 12 hours. Diet adherence and progress will be assessed daily using at-home blood ketone/glucose monitors, along with diet records. Participants will fill out health related questionnaires and undergo assessments of body composition, RA disease activity. This study also includes blood draws and fat biopsy of the abdominal region.
The primary objective of this study is to histologically evaluate the incorporation of AlloMend® Acellular Dermal Matrix into surrounding native soft tissue. Adults 18 years of age or greater who have undergone a pre-pectoral placement of tissue expanders for breast reconstruction and will have a histological evaluation of the AlloMend® Acellular Dermal Matrix and native tissue at time of permanent breast implantation.
The use of titanium dental implants has become a common modern treatment to restore teeth. Although the success rate of dental implants is high, inflammation around the dental implant still occurs. The current study will investigate if the inflammation around the implant is due to bacterial infection, hypersensitivity or both. The goal of this cross-sectional study is to (1) Establish the levels of cytokines in peri-implant crevicular fluid associated with bacterial infection and hypersensitivity reaction; (2) Compare the levels of cytokines associated with hypersensitivity and bacterial infection between healthy implants and inflamed implants (peri-mucositis and peri-implantitis); (3) Determine whether the difference in the levels of cytokines, if they exist, reflects the clinical diagnosis of healthy implants and inflamed implants.
The goal of the project is to determine the difference in immune activation and HIV reservoir size between People living with HIV (PWH) on tenofovir-containing antiretroviral therapy (ART) versus PWH on nucleoside reverse transcriptase inhibitor (NRTI)-sparing ART. Tenofovir (TFV), a phosphonated nucleoside reverse transcriptase inhibitor (NRTI), is being used for oral pre-exposure prophylaxis (PrEP). The investigators will test this hypothesis: tenofovir, and perhaps NRTIs in general, stimulate a type I/III interferon also in PWH who take these drugs. Because chronic interferon stimulation may promote the survival and proliferation of cells with integrated provirus, the investigators also hypothesize that these drugs antagonize decay of the HIV latent reservoir in PWH on ART. Consequently, the researchers hypothesize that PWH who have switched from NRTI-containing ART to NRTI-sparing ART exhibit lower type I/III interferon pathway activation and lower latent HIV reservoir size. The investigators also hypothesize that independently of treatment, the extent of type I/III interferon activation correlates with latent HIV reservoir size. Thus, the proposed study seeks to answer these two questions. Can the gastrointestinal epithelium be impacted by ART, and contribute to chronic immune activation and expansion of the HIV-1 reservoir? If so, what therapeutic approaches can the investigators implement to reduce the HIV-1 proviral load? The data will reveal pathways that can be targeted therapeutically to treat chronic immune activation in PWH. The findings of this study will immediately translate to optimize the standard of care in PWH.
A randomized, double blind, study of dronabinol as a palliative agent in the treatment of pain, inflammation, and other complications of sickle cell disease (SCD).
Neuroinflammation can be an important regulator of long COVID, specifically fatigue and cognitive complaints. There is evidence that peripheral inflammation and neuro-inflammation are involved in fatigue and cognitive complaints, but precise pathophysiological mechanisms and causal relationship with viral infections are still unknown. The primary aim of this study is to quantify neuroinflammation with [18F]DPA-714 (TSPO-binding) PET scans in post-COVID-19 patients with and without post-infectious fatigue and cognitive complaints and relate it to cognitive, psychiatric and post-infectious fatigue symptoms.
Background: COVID-19 can cause problems in different parts of the body. For most people, it causes fevers or trouble breathing. Some people might not recover all the way. Researchers want to see if a treatment can help with people who have recovered from COVID-19 but still have symptoms ("Long COVID"). Objective: To learn if human immunoglobulin (IVIG) will help with neurological symptoms of Long COVID. Eligibility: Adults ages 18 and older who had COVID-19 at least 12 weeks ago and have ongoing neurologic symptoms, such as dizziness, trouble walking, or problems with strength. Design: Participants will be screened with a medical record review. Participants will have a medical history and a physical exam and complete questionnaires about their health and quality of life. They will have a spinal tap. They will give blood samples. They will discuss their symptoms with a neurologist and have a neurological exam. Participants will take memory and thinking tests using a tablet. The tests will take 1 hour to complete. They will also take a smell and taste test. It will take approximately 30 minutes to complete. Participants will lie on a table that tilts for up to 40 minutes. Their blood pressure and heart rate will be monitored. Blood will be taken through an intravenous (IV) catheter. Participants will receive either IVIG, or saline by IV for 5 days. Then the participants will receive IVIG if they first received saline or saline if they first received IVIG by IV for another 5 days. They will not know what they receive. Participants will have an MRI of the brain if they have not had one recently. They will receive a contrast agent by IV as part of the MRI scan. Participants will be on the study for up to 4 months. They will have follow-up visits at the clinical center as well as fill out questionnaires at home. They may be asked to continue follow-up....
The aim of this research project is to explore the acute impact of specific foods and beverages, which have been shown to be associated with inflammatory processes, mainly in epidemiological studies, on inflammatory and oxidative stress parameters in healthy humans following a high intensity physical workout.
The aim of this study is to assess if there are significant differences in periodontal conditions between patients undergoing fixed orthodontic treatment with stainless steel or ceramic brackets. For this study, patients will be enrolled and divided into two groups, according to the type of brackets (stainless steel or ceramic) used for orthodontic treatment. A professional supragingival and subgingival oral hygiene will be performed before the bonding of the orthodontic brackets together with a periodontal evaluation will be recording the following periodontal indices: PPD, BoP, BS, GI, PI, BEWE and Schiff Air Index. Indices will be recorded after 1, 3 and 6 months after the bonding, separately for both in maxillary and in mandibular dental arches and only for teeth with brackets bonded.
Study Aims 1. Understanding the gut microbiome profile in very low birth weight infants with or without ROP. The onset and aggravation of ROP and their relationship with gut microbiome will be examined. 2. Understanding the serum inflammatory cytokine profile in these infants and its relationship with the onset and progression of ROP. Their changes and association with the other systemic disorders such as NEC or RDS or sepsis will be explored. 3. Examiningthe associations amongmicrobiome profile and serum inflammatory cytokines and their relationship with ROP clinical features (prematurity without ROP, ROP without treatment, and ROP with treatment) in the study participant
