Filter by:Background: There is some evidence demonstrating the effect of psychological interventions in improvements in health biological parameters. To best of our knowledge, no study had addressed the impact of any psychological intervention on extracellular vesicles. In addition, Mindfulness-Based Cognitive Therapy (MBCT) and Emotion Focused Therapy for Cancer Recovery (EFT-CR) in the group have never been explored regarding extracellular vesicles and the effectiveness of these was not compared yet. Objectives: 1. To explore and compare the effect of MBCT and EFT-CR on biological parameters and psychological variables in distressed people who have had breast, prostate and colorectal cancer; 2. In addition, we will explore the acceptability through recruitment and retention rates of MBCT and EFT-CR in group and evaluate whether these interventions are appropriate for a larger clinical trial. Methods: The design of this study is a parallel randomized controlled trial. Participants will be randomized into MBCT, EFT-CR or usual care. Outcome measures will be assessed before, at the end of the intervention (8 weeks) and follow-ups (24 and 52 weeks from the baseline moment). Hypotheses: The researchers expected that both interventions will have an effect on extracellular vesicles and other study biomarkers as well as improvements in psychological outcomes, compared to treatment as usual (TAU) group. Regarding the comparative effectiveness, we did not have evidence to hypothesize which one of the interventions will be superior in both biological (extracellular vesicles) and psychological outcomes. Contribution for practice: The results of this preliminary study would permit to know if there are benefits of these psychological interventions on changes in extracellular vesicles and on psychological outcomes related to health. In addition, this study will permit to determine the acceptability of conducting a larger randomized controlled trial.
Background: The way the body heals and protects itself from getting sick is called the immune response. Some people with weak immune systems get sick often or get rashes and skin infections. Researchers want to find out how the immune system and skin problems are related so they can help these people. Objective: To learn about how immune response and skin healing are related to each other. Eligibility: People ages 18-65 with hyper IgE syndrome or Job syndrome or people ages 7-65 with chronic granulomatous disease. Healthy volunteers ages 18 65 are also needed. Design: Participants will be screened with: Medical history Physical exam Possible urine tests Participants will have 1 to 3 visits within about a week. Visits will include the following: Participants will have a wells device strapped to the inside of the forearm. It will suction the skin and pull the top layer away to form 8 blisters. The skin over the blisters and the liquid inside will be collected. Participants will have up to 4 skin biopsies. A sharp tool will remove a small plug of skin from the forearm. Participants may have blood and urine tests. The skin on participants skin will be rubbed with a cotton swab. Some participants will have an overnight visit. They will have the blister device placed back on the arm. The wells will be lined up over the blister wounds. The wells will be filled with either saline or the participant s blood serum. The device will be covered and left on the arm for up to 24 hours. Doctors will periodically remove some liquid from the wells.
Trabeculectomy is an ocular surgery intended to reduce intra-ocular pressure the surgery creates a sub-conjunctival filtering bleb which filters aqueous humor fluid out. A rather common adverse event of the surgery is increasing vascularity of the conjunctiva overlying the bleb. This leads to adherence of the conjunctiva to the sclera and fibrosis and finally failure of the bleb (and of the surgery) this study intends to demonstrate that post operative subconjunctival bevacizumab injection will reduce incidence of bleb vascularity and ultimately, bleb failure.
