Filter by:Gut microbiota were assessed in 540 colonoscopy-screened adults by 16S rRNA gene sequencing of stool samples. Investigators compared gut microbiota diversity, overall composition, and normalized taxon abundance among these groups.
The purpose of this study is to determine the efficacy and safety of omalizumab compared with placebo in adult participants with chronic rhinosinusitis with nasal polyps (CRSwNP) who have had an inadequate response to standard-of-care treatments. Study GA39855 (POLYP 2; NCT03280537) was another Phase III study by the Sponsor with identical objectives and design and was run in parallel with this study.

When a polyp is found, we begin to wash it and observe it with OE mode 1.Then,the endoscopist gives a real-time optical diagnosis and the future surveillance interval.Finally,the polyp will be resected for the biopsy.
Nasal polyposis is a chronic inflammatory disease of the nose and sinuses. GlaxoSmithKline (GSK) is embarking on a clinical program to assess treatment of severe, recurrent nasal polyps with an anti-interleukin-5 (anti-IL5) (mepolizumab). Subject specific symptomatic endpoints will form the basis for the assessment of treatment benefit of nasal polyp therapies. However, there is a lack of published qualitative data regarding nasal polyps to understand the symptoms or health-related quality of life (HRQoL) impacts. This cross-sectional qualitative study aims to address this unmet gap by conducting semi-structured combined concept elicitation (CE) and cognitive debriefing (CD) telephone interviews and real-time data capture. The combined CE and CD interviews (each 90 minutes in duration) will investigate the subject experience of nasal polyps, and the relevance and understanding of existing patient-reported outcomes (PRO) instruments. The real-time data capture conducted over a 10 day period, will investigate the subject experience of the symptoms, HRQoL impacts and treatment of nasal polyps and any day-to-day variability that exists in these experiences in 'real time'. Twenty adult subjects in the United States (US), and 10 adult subjects in Germany with severe, recurrent nasal polyps will participate in the CE and CD interviews section of the study and of these, 10 subjects from US will also complete real-time data capture app task.
Hippo-YAP pathway is a newly discovered pathway controlling the growth, and plays important roles in the regulation of stem cell function and tissue regeneration. Previously we found that a higher expression of YAP in NP, and LPS was able to activate the hippo-YAP pathway in NESCs. Thus, we hypothesize that the aberrant proliferation and differentiation of NESCs could be regulated via the hippo-YAP pathway.
Pivotal trials of SDC2 methylation biomarker test in stool DNA to estimate clinical sensitivity and specificity in detection of colorectal cancer.
We aimed to compare the efficacy for bowel cleansing of a split-dose regimen with a low morning dose of PEG solution (Asymmetric; 25% of the dose is given on the day of the procedure and 75% of the dose is given on the day before) with the standard split-dose regimen in patients undergoing screening and surveillance colonoscopy using a low volume bowel preparation (2L PEG-citrate-simethicone plus Bisacodyl). We enrolled consecutive outpatients undergoing screening and surveillance colonoscopy in a randomized, single-blind, non-inferiority clinical trial. Patients were randomly assigned to: group A, asymmetric split dose regimen (1,5 L of PEG + bisacodyl the day before and 0,5 L 4 hours before colonoscopy); group B, symmetric split dose regimen (1 L of PEG + bisacodyl the day before and 1 L 5 hours before colonoscopy). Primary endpoint was the proportion of adequate bowel cleansing. Moreover, all patients filled in a nurse-administered questionnaire assessing compliance, tolerability and safety of bowel preparation.
Chronic rhinosinusits (CRS) is common disease with reports of prevalence ranging from 4-16% in the western population. The main outcome measure for chronic disease treatment, such as CRS, is quality of life. Several large multi-institutional studies have shown that improvement in disease specific Quality of life was greater in patients who had surgery for their CRS with polyps. The timing of surgery in these patients has not been well studied but it is generally agreed upon that surgical candidates much had failed medical management. The definition of medical management varies greatly but usually includes some form of nasal or oral steroids and a prolonged ( >10 days) course of antibiotics. Another known way to improve QOL is through education and individualized optimization. This has been utilized successfully in other fields with good success and improved QOL. Similar studies looking at combining non-surgical optimization and education have not been performed in CRS. This study aims to address this potential area for improvement in patient quality of life outcomes. Investigators plan to assess the potential role for pre-operative non-surgical medical and educational optimization in CRS standard of care treatment.
Small growths detected in the colon (polyps) during a colonoscopy may or may not have the potential to develop into cancer. However, since visual inspection alone cannot separate all potentially harmful polyps from harmless ones, the standard approach is to remove them all for histological lab examination, exposing patients to risk of injury and putting a significant demand on hospital resources. An accurate method of determining polyp type during endoscopy would enable the clinician to only remove potentially harmful polyps. A new endoscopic optical imaging probe (OPTIC), which analyses how light interacts with tissue, is proposed to do this. The probe is contained within a normal endoscope and uses white light and blue/violet laser light to illuminate the tissue. The reflected and fluorescent light emitted, along with normal colour pictures of the polyp surface, are measured and recorded to quantify specific characteristics of each type. Optical measurements of polyps detected in endoscopy clinics at Imperial College Healthcare NHS Trust will be analysed to determine if the signal can be used to differentiate different polyp types.
