Filter by:By doing this study, the investigator hopes to learn how the levels of important proteins involved in inflammation change over time in patients with acute brain injury. The total amount of time participants will be asked to volunteer for this study is approximately two hours over a five day period.
The investigators wish to determine how suture spacing (5 mm vs. 10 mm) affects cosmetic outcome and development of "train tracking" in wounds. Linear wounds with sutures spaced closer together may not be as cosmetically appealing when compared to those that have larger spacing between sutures. Suturing closer together constricts blood flow and increases tension that ultimately results in more tissue necrosis and a less appealing outcome. The investigators also aim to conclude if 5 mm or 10 mm suture spacing results in less complications.
This study will determine the impact of Transcutaneous Vagus Stimulation(TVNS) and autonomic modulation of inflammation in patients admitted with " acute heart attack." After admission for "acute heart attack" or "myocardial infarction" patients will be randomized to either TVNS or placebo and their blood samples will be collected at different time points during admission and post discharge. Blood samples will be analyzed for various markers of inflammation.
This study investigates the chronic long-term health condition of obesity and its effect on neutrophil function and the inflammatory response
Current data are showing a potential link between inflammatory biomarkers in chronic periodontitis and COPD. However the impact of periodontal treatment on systemic inflammation as measured by biomarkers and time to occurrence of acute exacerbations (AECOPD) remains an important but unresolved issue. This pilot study will provide information on effects of periodontal treatment on systemic inflammation and the course of COPD including acute exacerbation. 40 patients with chronic periodontitis and COPD will be included in this study. First baseline information (age, gender, lifestyle, smoking history, medical history, medication, frequency of exacerbation, dental treatments) are recorded. Then patient's health status is assessed using the COPD Assessment Test (CAT) and a comprehensive lung function testing (bodyplethysmograph) is conducted to assess lung functional severity of COPD. Blood samples are taken for analysis of various inflammatory biomarkers and saliva and sputum samples are collected for analysis of microbiome. Afterwards experienced dentists will conduct oral health examination and record the periodontal conditions of every patient. Samples of gingival crevicular fluid for determining Matrix metallopeptidase 8 (MMP8), Interleukin 1 beta (IL-1beta) and Interleukin 6 (IL-69 levels and for microbiome analysis will be taken. After randomization to one of the two study groups (intervention group: periodontal treatment / control group: no periodontal treatment) all patients get comprehensive oral hygiene instructions, irrespective of their periodontal status . Patients of the control group receive no further planned dental intervention. For patients of the experimental group, who need periodontal treatment due to the presence of periodontal pocket depth of ≥ 4 mm an appropriate care plan will be determined and supra- and subgingival scaling and root planing will be performed. During a 3, 6 and 12 months follow-up patient's current health condition will be assessed using the CAT. Additionally lung function tests (bodyplethysmograph) will be performed and clinical periodontal parameters are re-evaluated. To detect and assess COPD exacerbations in this trial, patients will complete a daily diary during the whole follow-up period which will be provided to the clinical researcher at each study visit. Furthermore the cough and sputum assessment questionnaire (CASA-Q)) will be used at each telephone call and at each visit in the pulmonary center. After 6 and 12 months blood, sputum, saliva and gingival crevicular fluid will be taken additionally. To understand the microbial ecology mechanisms linking periodontitis to COPD combined analysis of oral cavity microbiome (GCF) and lung microbiome (sputum) will be conducted. The biomarkers high sensitive C-reactive Protein (hsCRP), MMP8, IL-1beta und IL-6 will be determined in blood and in gingival crevicular fluid, respectively.
Background: PIDD stands for primary immune dysregulation. It is a general term that includes many different inherited immune system disorders. The immune system is the part of the body that helps fight disease and infection. People with PIDDs can develop many kinds of health problems. One of these is inflammatory bowel disease (IBD), which causes diarrhea and cramping. Researchers want to learn more about these disorders to develop possible treatments. Objective: To learn more about when and why IBD may develop in some people with PIDDs. Eligibility: People ages 3 and older who have PIDD or IBD. Healthy volunteers in this age group are also needed. Design: Visit 1: Participants will be screened with physical exam, medical history, and blood and urine tests. Visit 2: Participants will: - Have more physical exams and blood and urine tests. - Answer questions about quality of life and food history. - Provide a stool sample. - Have nasal and rectal skin swabs. - Have saliva collected. Participants will have 1 follow-up visit per year. They will repeat visit 2 procedures. Participants will be contacted by phone or email in between yearly visits. They will be asked about their health. They will complete a quality-of-life questionnaire and send a stool sample that is collected at home. If participants experience a sudden change in symptoms or undergo a new treatment, they may be asked to complete visit 2 procedures. If participants are not able to come to NIH, study data and samples can be collected without an in-person visit. Participants will have a final study visit about 10 years after Visit 1. They will repeat visit 2 procedures.
Objective: The present study was to evaluate the effects of dexmedetomidine alone, lidocaine alone and their combined infusion on postoperative inflammation cytokines after Laparoscopic hysterectomy. Methods: Investigators enrolled 160 women with American Society of Anesthesiologists (ASA) physical status I and II, aged 40-65 years, and scheduled for elective laparoscopic hysterectomy with general anesthesia from October 2017 to August 2018. The participants were randomly assigned into four groups(n=40 each group): group CON received normal saline infusion, group LIDO received lidocaine infusion (1.5 mg/kg loading, 1.5 mg/kg/h infusion), group DEX received dexmedetomidine infusion (0.5 µg/kg loading, 0.4 µg/kg/h infusion) and group LIDO+DEX received lidocaine (1.5 mg/kg loading, 1.5 mg/kg/h infusion) and dexmedetomidine infusions (0.5 µg/kg loading, 0.4 µg/kg/h infusion). The four groups received an IV bolus infusion of normal saline, lidocaine, dexmedetomidine and lidocaine combined with dexmedetomidine respectively, over 10 minutes before induction of anesthesia, followed by a continuous IV infusion of normal saline, lidocaine, dexmedetomidine and lidocaine combined with dexmedetomidine until abdominal wound closure, respectively. Interleukin-6 and tumor necrosis factor-α levels in serum were measured at different time points: before administration of drugs (T1), the end of surgery (T2), postoperative 2 hour (T3) and postoperative 24 hour (T4).
The primary objective is to contrast the degree to which increased consumption of dietary fiber vs. fermented food can decrease inflammation, increase microbiota diversity and can impact microbiota production of short-chain fatty acids (SCFA), potential normalizers of metabolic and immune dysfunction, in obese and non-obese adults.
The aim of this study was to investigate the airway inflammatory profile and the clinical presentation of chronic obstructive pulmonary disease (COPD) in never smokers compared to smokers with COPD.
The goal of this research project is to explore if levels of inflammation predict levels of comorbid mood disorders and treatment success in chronic pain patients. More knowledge in this respect will advance our understanding of chronic pain and comorbid syndromes, and facilitate subgroupings of patients based on the presence and/or level of low-grade inflammation. This research is an important step towards finding an explanation to why treatment effects following behavioral interventions differ across individuals, and generate new hypothesis regarding novel treatment approaches. The specific aims are: 1) to explore if baseline levels of inflammatory biomarkers predict the effects of behavioral intervention and 2) to investigate if baseline levels of inflammatory biomarkers are associated with psychological co-morbidity (e.g. depression, anxiety and fatigue) in patients with chronic pain.
