Filter by:The purpose of this study is to see if the front part of the brain called the "Dorsolateral Prefrontal Cortex" (DLPFC) has a role in our ability to feel breathlessness. The experiment will use a device that sits on the top of the head which produces a magnetic field that penetrates the scalp and excites the brain tissue directly under it. This procedure is called repetitive transcranial magnetic stimulation (rTMS), it is a painless procedure and known to be safe in healthy individuals. Previous research has shown that the pain felt when capsaicin, the active ingredient in 'chilli' powder, is applied to the hand is reduced by applying the rTMS on the scalp directly above the DLPFC part of the brain. In this experiment we want to see if breathlessness is also reduced. We will use a breathing task that will generate a moderate amount of breathlessness by adding a small amount of carbon dioxide to the inhaled air, while preventing the increase in the amount of breathing we would normally see in response to this. If we find that breathlessness produced by this breathing task is reduced after rTMS over the DLPFC, this may lead to new drugs that target this part of the brain in patients suffering from breathlessness due to heart or lung disease. The study will also improve our knowledge of how the brain enables us to feel breathlessness
The goal of this interventional study is to compare muscle reflex function under settings of normoxia (normal oxygen level), acute hypoxia (brief oxygen-lack) and chronic hypoxia (long-duration exposure to oxygen-lack). The main question is: Does the muscle reflex adapt to chronic hypoxia? Young, healthy participants will complete light-to-high intensity cycling exercise with and without suppression of the muscle reflex. Suppression of the muscle reflex will be via spinal administration of the opioid Fentanyl. In the control condition, saline will be administered into the spinal space. Participants will complete control (saline) and experimental (Fentanyl) exercise conditions at sea-level (Kelowna, BC, Canada) breathing room air and whilst breathing a lower fraction of oxygen (acute hypoxia). Thereafter, participants will complete the exercise test after living at high altitude (White Mountain, CA, USA) for 2 weeks whilst breathing room air (chronic hypoxia) and breathing a higher fraction of oxygen (restored normoxia).
This study will be a Randomized controlled and will be conducted in Allied Hospital, Faisalabad. The study will be completed within the duration of 10 months. Convenience sampling study technique will be used to collect the data. The sample size of 30 patients will be taken in this study to find the effect of flutter and PEP mask therapy on chest clearance and dyspnea. Patients will be allocated randomly in two groups and 15 patients in each group. Group A will get flutter device therapy. Group B will get PEP mask treatment. A regular follow up visits to department and a final assessment was made at the end of last week by using questionnaire and resulting improvement was shown in results after completion. Data will be analyzed on SPSS25.
This randomized clinical trial aims to evaluate patients with decompensated heart failure undergoing an early mobilization protocol with the use of immersive virtual reality glasses compared with patients undergoing the same protocol but without immersive virtual reality. The primary outcome will be the sensation of difficulty breathing, and the secondary outcome will be whether this technology provided a positive experience for patients in the intervention group that was superior to that of patients in the control group.
It will be a randomized control trial at Services Hospital Lahore through convenience sampling technique which will be allocated through simple random sampling through sealed opaque enveloped in to Group A and Group B . Group A: patients will be treated with basic breathing technique whereas Group B: will be treated by will be breathing technique along with diaphragm and abdominal training. The study will be completed within 6 months after synopsis approval from ethical Committee of RCRS & AHS . Data will be entered and analyzed by SPSS version 25. After assessing the normality of data , it will be decided either parametric or non-parametric test will be use within a group or between two groups.
EFFECTS OF INCENTIVE SPIROMETRY ON DYSPNEA AND CHEST CLEARANCE IN ASTHMATIC PATIENTS DURING SEASONAL SMOG
The objective of this study is to evaluate the feasibility of a walking football intervention for people with chronic breathlessness. Chronic breathlessness refers to breathlessness that persists despite optimal treatment of the underlying pathophysiology. Roughly 9-13% of the general population will experience chronic breathlessness, with incidence rising with age to 37% for those aged over 60years. This mixed-methods study will offer patients who have enrolled on to pulmonary rehabilitation (PR) the prospect to partake in walking football once they have completed their scheduled programmes (or voluntarily dropped-out); introducing a potential opportunity for long-term exercise maintenance post PR. Participants will be recruited from North Tees & Hartlepool Foundation Trust, and South Tees Foundation Trust. PR is recommended for all people with chronic breathlessness and has been shown to improve exercise capacity and health-related quality of life. However, PR programmes typically only last for 6-12 weeks, and have little to no impact on long-term physical activity levels. Walking Football has been identified as a potential form of exercise which people with breathlessness could maintain post-PR, thus offering a solution to PRs limited ability to promote exercise maintenance. Participants will be invited to play walking football for 6-weeks (2-hours weekly) in the Middlesbrough/Stockton area. Before and after weeks 1 and 6, breathlessness-relevant outcomes will be measured including; exercise capacity, lower-limb strength, perceived breathlessness, quality of life, balance confidence, depression, and anxiety. During a participant's third session, one-time physical intensity outcomes will be calculated during play including heart-rate and perceived intensity. Participants will also be invited to an interview to discuss how feasible they have found the football, any benefits they may have experienced, and how the football programme could be improved. The study will officially end with a co-production workshop; a focus group with stakeholders (players, physiotherapists, co-ordinators, researchers) after preliminary analysis has been conducted to discuss initial findings.
The aim of this study is to identify correlations between change from the baseline at Month 24 in Forced Vital Capacity (FVC) (% predicted and mL) and change from the baseline at Month 24 in cough or dyspnoea scores [points] as measured in the living with pulmonary fibrosis questionnaire (L-PF) over 24 months of nintedanib treatment in patients with connective tissues disease-associated progressive fibrosing interstitial lung disease (CTD associated PF-ILD) under routine clinical practice conditions in Greece.
There is no specific tool existing to describe dyspnea in children in a multidimensional way. It has been shown in adult studies that multidimensional dyspnea evaluation scales are well correlated to quality of life and respiratory function impairments. The investigators hypothesis is that using multidimensional dyspnea evaluation scales could allow for a more systematic and precise evaluation of this symptom in children, thus improving management and follow-up of patients presenting with acute (asthma attack, infectious diseases) and chronic (cystic fibrosis, primary ciliary diskynesia, neuromuscular diseases) respiratory insufficiency.
To evaluate the role of exercise hemodynamic testing in the diagnostic workup for patients with dyspnea on exertion referred to the catheterization lab.
