Filter by:Patients undergoing major head and neck surgery are at risk for postoperative pulmonary complications. The goal of this randomized clinical trial is to evaluate the effectiveness of high flow heated humidified oxygen at preventing postoperative pulmonary complications after major head and neck surgery, when compared to conventional oxygen therapy (aerosol cool mist).
This study proposes an approach to address an urgent unmet need in clinical practice, namely a pragmatic method of establishing what is the cause of a patient's complaint and the next steps to address this problem. In this study, the investigators will compare the proposed classification with current best practice of self-report, spirometry and FeNO. The investigators will compare the two approaches with a gold standard of deep characterisation by 3 separate diagnostic tests. The investigators hypothesize that patients with symptoms of respiratory disease fall into one of four working groups based on accurate knowledge of three parameters, airflow, treatment use and the patient's symptoms.
The aim of this study is to determine whether an intervention with frequent thermotherapy will be able to reduce the amount of colonizing bacteria in the bronchoalveolar lavage sample and eradicate the colonizing bacteria.
The Mindful Breathing Laboratory under the direction of Dr. Benzo will complete a randomized controlled trial to evaluate the mindful breathing module. This rigorous study will evaluate home-based PR system compared to the home-based PR system plus mindful breathing module for its effects on breathlessness and emotions. The investigators hypothesize that the intervention will decrease breathlessness while increasing emotional perception, emotional intelligence, and mindfulness.
The objective of this study is to identify key indicators in the follow-up of subjects with different pathologies related to both the person's environment, as well as the perception of their health and general quality of life and related to their disease. To this end, a cross-sectional observational study of qualitative data collection through questionnaires, mostly validated, has been proposed to try to identify these indicators. Based on these questionnaires, the specific objectives of this study are as follows: - Unify questionnaires - Assess data quality - Identify key indicators, through a factor analysis - Design a second reduced version of the questionnaires collecting the key indicators and eliminating those items that are exclusive to each other. In order to identify the key indicators, it will be necessary to measure at least 30 subjects from each pathological group, as well as a cohort of at least 100 subjects without pathologies in order to validate and contrast the results. The subjects will be recruited through the own databases of participants in previous trials of the Institute of Biomechanics of Valencia, who have given written consent to be contacted in order to request their participation in any other study where their profile may fit. They will also be recruited and contacted through the collaborating associations (Parkinson Valencia Association, Valencian Diabetes Association, Consorci Hospital General Universitari de València, Arnau de Vilanova Valencia Hospital). The surveys will be included in an online platform specialized in the realization of questionnaires. This data will be exported for further storage, management and analysis. All information will be anonymized for processing and analysis, and may be used under the terms and conditions dictated by the current legal framework. To participate in the study, participants must accept the terms and conditions included in the first page of the survey embedded in the online platform, where the aspects related to the study methodology and the use of them data are exposed. The statistical analysis will treat the data provided by the variables and how they are related to each other, testing differences according to the characteristics of the patient and clinical indicators. For that, non-parametric techniques such as the χ² test, the Kruskal-Wallis test and cluster analysis will be used.
Trials in COPD have shown that HIIT leads to the same positive outcomes as constant load training but causes less breathlessness and leg discomfort during training. However, HIIT protocols in existing trials have all been different and use relatively long interval durations (30 s) and short rests. This is sub-optimal because long interval durations lead to greater breathlessness and patients may fear that they will not fully recover during short rests, potentially decreasing adherence. A novel HIIT protocol involving very brief intervals (e.g. 10 s) with longer rests may provide the same benefits with less distress due to breathlessness.
This is a randomized, blinded, controlled clinical trial for mexican COPD patients. Biomass smoke associated COPD (BS-COPD) clinical spectrum is different to the one seen in tobacco smoke associated COPD (TS-COPD). BS-COPD patients present COPD-asthma phenotype or asthma-COPD overlap syndrome (ACOS), TS-COPD patients present mostly the emphysema phenotype. BS-COPD patients have a greater risk of exacerbations in comparison to the emphysema phenotype. Therefore, individualizing treatment in both phenotypes may be very useful among the clinical practitioners. The investigators expect treatment with FF/V to be superior in preventing COPD exacerbations than the U/V combination in patients with COPD-asthma phenotype; andU/V to be superior than FF/V in patients with the emphysema phenotype. The general objective of the study is to determine the exacerbations outcome in patients with COPD-asthma vs emphysema phenotype patients, treated with both drugs. Secondary objectives include assessment of pulmonary function tests, quality of life, dyspnea and functional capacity change after a 24 weeks treatment.
Scoring systems (SOFA, APACHE-II etc.) are used to estimate the mortality rates of patients treated in the intensive care unit. . In the scoring systems used, the disfunction level of the organs of the patients is measured. Blood gas analysis is routinely performed in patients whom intubated in the intensive care unit and receiving mechanical ventilation support, and the patient's treatment is optimized according to the results of the examination. The patient's mechanical ventilation settings are regulated by analyzing the Partial Arterial Carbondioxide (paCO2) value in the patient's blood gas result. The difference between the paCO2 value in the blood gas and the End-tidal Carbondioxide (EtCO2) value measured in the mechanical ventilator is 3-5mmHg in normal healthy people, while this difference is seen more in critical care patients. In critically ill patients in the intensive care unit, there is a greater increase in the difference between paCO2 and ETCO2 in cases where mortality is high, such as global perfusion disorder, shock situations, and massive pulmonary embolism, etc. In this study, it was planned to investigate the use of the difference between the paCO2 value in the blood gas taken from the patient and the ETCO2 value measured in the mechanical ventilator to predict the mortality rate of the patient.
Cardiovascular and respiratory diseases are the first and third cause of death, respectively. Cardiovascular risk is known to increase in groups with impaired lung function; however, the mechanisms behind this association are not fully understood. The aim of CaReS is to elucidate the shared pathophysiology of impaired lung function and cardiovascular risk, and to investigate the risk factors associated with them. The CaReS Cohort Study includes adults (18-80 years old) from Cartagena de Indias, a tropical city on Colombian Caribbean Coast, where recent population admixture settled a three-hybrid genetic structure (European, African and Ameridian ancestry). At baseline, the cohort will generate extensive data on -omics (e.g., genomics, transcriptomics, metabolomics, and epigenomics), socio-economic wellbeing, lifestyle, medical history, cardiometabolic, inflammatory and liver function markers, as well as objective measures of ventilatory and cardiovascular performance. The cohort will collect data every three years, for a total period of ten years. Prospective risk of cardiovascular disease and chronic obstructive pulmonary disease (COPD) will be investigated, and their risk factors. Throughout the study period, changes in prevalence, and interactions of various risk factors with these changes will also be ascertained. A predictive risk score for cardiovascular and chronic respiratory disability will be built, using cross-sectional and longitudinal data.
The primary objective of this study is to assess the safety and effectiveness of Human Multigene Methylation Detection Kit (Fluorescent PCR Method) for help diagnose lung cancer by comparing with clinical standard method (includes chest CT examination or pathological examination).
