Filter by:The purpose of this research study is to study the relationship between childhood asthma, allergies, and early-life environmental factors that may cause childhood asthma and allergies. Previous birth cohort studies have found early-life environmental factors such as allergies, pollutants, viruses and bacteria have all contributed to the development of asthma and allergies. Investigators are doing this research because there continues to be a strong need to understand the root causes of asthma and allergies. The CANOE study is an observational cohort study, which means investigators are not asking participants or participant's child to change their medications and investigators will not be giving participants or participant's child a study drug.
This randomized, placebo-controlled, triple-blind trial aims to evaluate the effect of glutaraldehyde associated or not with 37% phosphoric acid conditioning on dentin hypersensitivity reduction after non-surgical periodontal treatment, and its durability after 15 and 30 days. desensitizing treatment. Additionally, investigate the impact of these treatments on health-related quality of life. The investigators selected patients who, after scraping and planing procedures, presented at least 2 teeth meeting the following inclusion criteria: presence of gingival recession without or with a periodontal pocket up to 5mm probing depth, which presented painful sensitivity response to tactile stimulus. and evaporative. Subjects were randomized into 3 groups: Placebo Group (GP) - Placebo Gel application followed by Placebo solution (distilled water); GPG- Placebo Gel application followed by application 5% aqueous glutaraldehyde solution; GSG - Application of 37% phosphoric acid followed by 5% aqueous glutaraldehyde solution. The sensitivity of the dental elements was evaluated by pain stimuli (tactile and evaporative) with the aid of a Visual Analog Scale (VAS). A questionnaire was applied to patients with the objective of capturing psychosocial experiences, prior to treatment and one month after its completion, to assess the impact of desensitizing treatment on health-related quality of life. Data will be collected and appropriate statistical tests will be applied.
The aim is to test in T2DM patients, whether, compared to placebo, 12 weeks of SGLT-2 inhibitor improves post-absorptive, post-insulin infusion or postprandial insulin action to enhance Cardiac Muscle vascular function and whether changes correlate with improved GV or postprandial hyperglycemia
This proposed study aims to examine the effects of a culturally-sensitive theory-driven advance care planning (ACP) game in increasing the self-efficacy and readiness of ACP behaviours among Chinese community-dwelling older adults. This is a mixed methods study with the quantitative paradigm being the main research approached used. The quantitative arm will be a randomized controlled trial (RCT). The qualitative arm will adopt focus group interviews for data collection. Recruited subjects from the community centres will be randomly allocated to the intervention and control group. The older adults in the experimental group will receive an ACP board game delivered by trained facilitators, whereas the older adults in the control group will receive another board game about healthy lifestyle. The outcome measures of the older adults will include the ACP Engagement scale, the Life-Support Preferences Questionnaire (LSPQ), a self-developed ACP knowledge questionnaire and those data will be collected at baseline (T0), immediately post-intervention(T1), at 1 month (T2), and 3 month (T3). The qualitative arm of this study will contribute to the understanding of issues and effects of ACP game as an intervention. Its finding will complement the results obtained from the RCT.
Use of three intralymphatic injections of peanut allergen one month apart to induce tolerance to peanut in peanut allergic people.
Clinical supervision (CS) is a pragmatic approach, which enables nurses to work together; it can create a positive nursing environment, reduce stress, and increase clinical skills through peer support. Previous research has demonstrated its positive effects on nurses wellbeing, sense of coherence, and professional accountability. However, there is lack of evidence for its influence on cultural sensitivity. The Qatar National Health Strategy (Ministry of Public Health, 2018) and the Qatar National Mental Health Strategy (Supreme Council of Health, Qatar, 2013) have both given significant importance on building the health workforce capacity to meet the growing needs of the population. Aligning with these strategies, Hamad Medical Corporation (HMC) Mental Health Service's Executive Committee has taken a decision to implement clinical supervision to develop a supporting framework to strengthen the professional skills of the nursing workforce. In order to implement it efficiently, guidelines and education curriculum have been developed. The aim of the study is to evaluate the implementation of CS. In addition, investigators will also explore the impact of clinical supervision on the work-related strain, sense of coherence, cultural sensitivity and the impact on patient care. A longitudinal approach will be adopted using pre and post-testing. The required power sample size is calculated to be 136 nurses. Enrolled participants will receive an educational programme regarding clinical supervision and will be requested to choose a supervisor based on their learning requirements. Through the clinical supervision process, supervisee self-reflection, facilitated by the supervisor. The supervisor will, in addition, enable opportunities for professional growth by the sharing of skills and knowledge in relation to particular clinical challenges. In addition, they will also provide opportunities for emotional restoration through the exploration of stressful issues that have occurred in the workplace. Participants will be scheduled to engage in one to one sessions with their supervisor once a month for an hour. The study will be conducted for 18 months (2 months for baseline data collection, 2 months for educational preparation, 12 months of intervention and lastly 2 months for post-intervention data collection) from the date of the participant's enrollment. The outcome measures include the sense of coherence, work-related strain, cultural sensitivity, the total number of nurse instigated Occurrence, Variance and Accident (OVA) initiated during the course of this study and the efficacy of clinical supervision sessions. Data will be collected before education sessions are delivered (baseline), at 6th month and at the 12th month. The investigators will use the Statistical Package for the Social Sciences (SPSS) and STATA for analysis. The study may identify an effective way of reducing work-related strain and enhancing the sense of coherence, cultural sensitivity, and quality of patient care.
The investigators hypothesize that cycling for 1 hour of exercise at 65% peak oxygen consumption (VO2peak) after sitting >13 hr/day (SIT+EX) will not be different in postprandial plasma insulin responses compared to the control of only sitting (SIT). Furthermore, the investigators hypothesize that the SIT and SIT+EX groups will have a less favorble insulin response compared to the physically active group after performing the same 1-hour exercise bout (ACTIVE+EX).
This study will assess the efficacy and safety of pembrolizumab plus enzalutamide plus Androgen Deprivation Therapy (ADT) versus placebo plus enzalutamide plus ADT in participants with mHSPC. The primary hypothesis is that in participants with mHSPC, the combination of pembrolizumab plus enzalutamide plus ADT is superior to placebo plus enzalutamide plus ADT with respect to 1) radiographic progression-free survival (rPFS) per Prostate Cancer Working Group (PCWG)-modified Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 as assessed by blinded independent central review (BICR) and 2) overall survival (OS). As of 19-JAN-2023, the study was unblinded and all study participants stopped ongoing treatment with pembrolizumab/placebo and will continue to receive Standard of Care treatment until meeting protocol-specified discontinuation criteria if deriving clinical benefit. Safety analysis will be performed at the end of the study; there will be no further analyses for efficacy and electronic patient-reported outcome (ePRO) endpoints collected from participants beyond the IA1 cutoff date. All study participants will stop ongoing treatment with pembrolizumab/placebo. Exceptions may be requested for study participants who, in the assessment of their study physician, are benefitting from the combination of enzalutamide and pembrolizumab, after consulting with the Sponsor. All other study participants should be discontinued from study and be offered standard of care (SOC) treatment as deemed necessary by the Investigator. If enzalutamide as SOC is not accessible off study to the participant, central sourcing may continue. As of Amendment 04, disease progression will no longer be centrally verified, participants will only be assessed locally. As of Amendment 4, Second Course treatment is not an option for participants. There are currently no participants in the Second Course Phase.
In 2001-2002, a longitudinal study on the risk of atopic sensitization in children was conducted by the Pneumo-Allergology and Pediatrics departments of the CHU Saint-Pierre Hospital and at the Neonatology Department of the Queen Fabiola Children's University Hospital (HUDERF). The aim of the study was to study bacteria and endotoxins in airborne dust in Brussels homes in order to evaluate their impact on the development of allergic diseases in newborns. Between December 2000 and August 2002, 114 children (67 from HUDERF and 47 from CHU St-Pierre) were included in the study. These were eutrophic children without acquired pathology or known genetics. Simultaneously a microbial habitat assessment was performed based on a detailed description and on endotoxin assays in the airborne and deposited dust (mainly mattress).These data can be used to define habitats with high or low contamination.Samples for microbial analyzes (Gram positive and negative and mold) were also carried out. Preliminary results suggested: 1. A protective effect of airborne dust endotoxins on the risk of developing atopic dermatitis in children at 6 and 12 months of life, 2. An effect of endotoxins promoting the occurrence of wheezing in children after 6 months. In this current, new study, the investigators will recontact the children who were included in the 2003 study. The goal is to evaluate them clinically and allergically and associate the risk of sensitization / allergic diseases with the microbial exposure of the habitat, measured during the neonatal period. Siblings and parents who were exposed during the same period will also be evaluated.
Birth cohort study with recruitment during pregnancy to determine prenatal and perinatal conditions, as well as genetic and epigenetic factors, that participate in the early setting of immune responses, and the role of these in the later determination of the risk of allergic diseases, asthma, and metabolic conditions in the offspring.
