Filter by:This prospective, observational study is designed to investigate clinical outcomes and collect patient feedback on the use of Wellinks, an integrated virtual chronic obstructive pulmonary disease (COPD) management solution, for patients recently discharged from the hospital due to an acute exacerbation of their COPD.
Some components of the diet could promote the growth of certain bacterial strains present in the intestine, which are closely associated with benefits for host health. An intestinal commensal Parabacteroides goldsteinii (Pg) was highlighted to be significantly negatively associated with severity of COPD. Furthermore, the investigators identify the potential prebiotics (PHGG) which may enrich the abundance of P. goldsteinii and increase the probiotic effect of P. goldsteinii. The investigators designed a randomized control study, which enroll adults diagnosed with COPD. Then the two groups will receive PHGG or not. Stool samples will be collected. The ameliorative efficacy will be evaluated by questionnaire and lung function test. Intestinal microbiota and metabolome will be analyzed and the correlation with lung function indices will be further investigated.
Drug-induced sleep endoscopy (DISE) is the most used technique for identifying the obstruction site associated with obstructive sleep apnea (OSA). This is due to the fact that it allows many patients to be examined in a daytime setting. This procedure uses sedative drugs to mimic natural sleep. However, associations with the site of upper airway (UA) collapse during natural sleep remain unclear. The aim of this explorative study is to identify UA collapse in patients with OSA using endoscopic techniques as well as flow shape characteristics and sound analyses during natural and drug-induced sleep. Furthermore, we want to optimize the measurement set-up of natural sleep endoscopy (NSE).
Project is designed as a comprehensive population-based epidemiological study in Upper-Silesian Conurbation (Poland) aiming at: 1. analysis of available data on incidence and mortality due to COVID-19 and 2. estimation of the occurrence of viral infection SARS-CoV-2 as revealed by the results of serological test (ELISA: IgM, IgG), with assessment of risk factors. The project's objectives are: to assess incidence and mortality due COVID-19 according to sex, age and coexisting diseases; to determine the level of potential "underdiagnosis" of the magnitude of COVID-19 mortality using vital statistics data for Upper-Silesian Conurbation; to assess the prevalence of SARS-CoV-2 based on the level of seropositivity in Upper-Silesian Conurbation; to identify host-related and environmental risk factors if the infection. Analysis of existing data will include monthly records on incidence and mortality over the period 01.01.2020-31.12.2020 and comparison of the findings with the monthly records of 2018 and 2019, for the same population. Cross-sectional epidemiological study will be located in three towne (Katowice, Sosnowiec, Gliwice). In each town a representative age-stratified sample of 2000 subjects will undergo questionnaire assessment and serological examination performed by serological test. The project corresponds with analogous population-based studies on COVID-19 in a number of countries and responds to the WHO recommendation in that field.
The SARS-CoV2 virus causes severe or even fatal disease in a fraction of infected people. The clinical severity is based on a complicated pneumopathy with acute respiratory distress syndrome that can lead to multi-visceral failure. The underlying mechanism is a cytokinergic storm, an emerging facet of immunological dysregulation. This clinical trial is aimed to understand the mechanisms of this immunological dysregulation in order to identify therapeutic levers. The main objective is to understand the relationships between clinical severity, death or morbidity of resuscitation management, and immune status (i.e., immune pathways activated or not). Immune status will be investigated at many levels of organization (i.e., circulating leukocytes, cytokines and chemokines, transcripts). The secondary objectives are : - to understand what is responsible for clinical severity, viral load, or immune activation; - to highlight the consequences of immunological dysregulation on associated risks (i.e., immunosuppression leading to the emergence of infectious comorbidities) as well as the functioning of neurotransmission through metabolic pathway diversions. The impact of dysimmunity on these biological pathways will be assessed with a metabolomic analysis; - to understand the mechanisms of vulnerability related to the field. Moreover, while co-morbidities are likely to be a risk factor for severe disease progression, there are many situations in which they do not occur. Stress, with its neurovegetative and endocrinological dimensions, modulates the immune response. It is essential to know whether the stress response plays a role in immunological dysregulation. This analysis is a prerequisite for understanding the conditions of treatment with glucocorticoids. Angiotensin converting enzyme type 2 (ACE2) also plays a likely role in host viral infection. It is also thought to play an important role in the emergence of severe syndromes by affecting the quality of vascular response.
Study ROR-PH-301, ADVANCE OUTCOMES, is designed to assess the efficacy and safety of ralinepag when added to pulmonary arterial hypertension (PAH) standard of care or PAH-specific background therapy in subjects with World Health Organization (WHO) Group 1 PAH.
Objectives: While a respiratory abnormality was found in 50% of pediatric renal transplant recipients in a study conducted in Belgium and the Netherlands in 2008, the respiratory status of transplanted children in France remains unknown. The primary objective of this study is to assess the prevalence of respiratory impairment and its characteristics in children with renal transplant. The secondary objective is to study its association with some potential risk factors such as immunosuppressive therapy or humoral immunodeficiency. Methodology: This interventional study aims to recruit the 385 children currently being followed by 5 French pediatric renal transplant centers between June 2018 and November 2019. A clinical and functional respiratory assessment will be carried out during the routine annual follow-up of the transplant recipient. Children with clinical signs of concern or abnormal spirometry will be referred to a respiratory specialist. Pharmacokinetic assays of immunosuppressant therapy and the exploration of humoral function will also be performed. The prevalence and type of respiratory abnormalities will be described. Logistic regression will be used to explore the association between potential risk factors and impaired respiratory function. Expected results: This study will be the first to evaluate the respiratory status of children with renal transplants in France. The prospective, multi- centered nature of the study, in addition to the large cohort size (which represents two thirds of children with renal transplants in France) will guarantee current, reliable, and representative data for the target population. We will provide new knowledge by precisely characterizing the type of lung injury and looking for potential risk factors. If our study confirms the high prevalence of pulmonary impairment in children with renal transplants, systematic monitoring of respiratory function may be recommended to enable early diagnosis and management. The expected individual and public health benefits would be significant by limiting the appearance of long-term, irreversible sequelae (such as non-cystic-fibrosis bronchiectasis) and improving the quality of life of these patients.
The purpose of the study on the Prevention of Influenza and Other Wintertime Respiratory Viruses among Healthcare Professionals in Israel Effectiveness of Influenza Vaccine in Preventing Influenza Virus Infection, Missed Work, and Patient Exposure: A Prospective Cohort Study of Healthcare Personnel (to be called the Healthcare Personnel or HCP study throughout this Data Security Plan) is to investigate vaccine effectiveness and respiratory illness among healthcare personnel (HCP). This will help to better understand the factors that influence influenza vaccination choice, individual vaccine response, and whether or not the influenza vaccine helps to prevent influenza in HCP.
This observation will look at patient care decisions of the primary healthcare provider utilizing the results of the DNA testing of patients' metabolic pathways using 2C19, 2C9, 2D6, 3A4, Factor II, Factor V and MTHFR and VKORC1. Findings of the data collection will be published to optimize the benefits of pharmacogenomics testing and publish health outcomes.
