Filter by:Since the spread of the COVID-19 disease, several studies have reported the presence of neurological symptoms in patients infected with SARS-CoV-2 such as dysgeusia, hypo or anosmia, hypopsia, the presence of headaches or neuralgia. It has also been described an inconsistent association, in the most severe patients, neurological disorders such as labile arterial hypertension, persistent central fever, vigilance disorders as well as a poor adaptation of the cardio vascular and respiratory systems characterized by paradoxical bradycardia and the frequent absence of polypnea in response to profound hypoxemia. These different functional signs are usually described in particular in patients with impairment of the autonomic nervous system (ANS) in connection with other neuropathological processes.
This is a double-blind, randomized, placebo-controlled study. The purpose of the clinical study is to determine the difference between 84 days of once daily oral EpiCor supplementation compared to placebo on the incidence of cold or flu symptoms among children aged 4-12 years who are attending school or daycare.
The effects of a tested and published music therapy respiratory protocol shown to be efficacious with pediatric asthma and adult COPD is being studied with individuals living with post-Covid-19 respiratory symptoms. An interventional, single arm study is being conducted with individuals meeting eligibility criteria detailed below. Primary outcome is a change in the MRC Dyspnea score, with secondary aims focusing on improved quality of life, including reduced fatigue and depression and improved sleep and resilience.
Background The respiratory tract often becomes the site of injury from occupational exposure. All construction sites generate high levels of dust, typically from concrete, silica, asbestos, cement, wood, stone, sand and therefore, the workers are exposed to this airborne dust and increased their risk of developing respiratory disorders. Limited studies have been conducted to assess the relationship between respiratory symptoms, lung function and occupational dust exposure among construction workers in Sabah. The objectives of this study are to determine the occupational exposure to dust and the relationship with the respiratory symptoms as well as lung function among construction workers in UMS Teaching Hospital. Materials and methods This cross-sectional study consisted of construction workers working in all sections in the development of UMS Teaching Hospital. A standard respiratory questionnaire was distributed to construction workers and lung function measurement was performed using Spirometry and the results of their respiratory status were compared between workers who were exposed and unexposed to dust. Occupational dust exposure was determined by the gravimetric method using an air sampler. The total duration of the collection was 8 hours and the filters with the dust samples were analyzed in the laboratory.
This is a phase I study to evaluate the safety and efficacy of inhaled Ampion on patients with prolonged respiratory symptoms due to COVID-19 (Long COVID).
The purpose of this study is to asses the efficacy of the Gammacore device reducing the need for mechanical ventilation in patients diagnosed of Covid-19
The purpose of the clinical study is to evaluate efficacy of regular daily, 12 weeks, consumption of EpiCor syrup containing EpiCor and vitamin C in non-vaccinated children 1-6 years old on preventing episodes of the common cold and flu as well as on the severity of symptoms of the common cold and flu in case of their occurrence. Additionally, the study aims to assess the effect of EpiCor on the use of prescription drugs and changes of a selected biochemical marker. This is a double-blind, randomized, controlled multi-center clinical trial.
This study examines the feasibility and acceptability of using mobile applications and biosensing (mHealth) devices in detecting vitality parameters in current smokers with and without respiratory symptoms/COPD (e.g., heart rate, blood oxygenation, steps/motion) for a future big-scale study.
--> This is a substudy of the main ESTxENDS trial (NCT03589989). Respiratory symptoms outcomes should be considered secondary outcomes of the main smoking cessation outcome formulated in NCT03589989. Cigarette smoking is the leading cause of preventable death in Switzerland. Cigarette smoking eventually kills one in two smokers, mostly through cancer, heart disease and respiratory failure. Recently, electronic nicotine delivery systems (ENDS; also called vaporizer or electronic cigarette) have become popular with smokers who want to stop smoking or reduce their exposure to inhaled chemicals since ENDS use appears to be safer than tobacco smoking. Studies suggest that ENDS use improves health outcomes, such as reducing respiratory symptoms, and presents only minimal respiratory risks, such as mild throat irritation and dry cough. In a prospective 6-month randomized, controlled trial evaluating smoking reduction/abstinence in 300 smokers not intending to quit experimenting two different nicotine strengths of a e-cigarette model compared to its non-nicotine choice, respiratory symptoms similarly improved in all three study groups. One study compared the short-term effects of cigarette smoking to ENDS use and found that cigarette smoking led to an acute reduction in lung function, which was not observed with ENDS. Findings on short-term airway resistance is conflicting. Short term increase in resistance in ENDS users might be caused by aerosolizing the liquid, and not by the same substances that harm lung function in cigarette smokers. Smokers who shifted from tobacco cigarettes to ENDS have offered anecdotes of dramatically improved lung function, but animal models suggest that ENDS liquids can increase markers of asthma. No large randomized trials have tested the effect of ENDS on respiratory symptoms. For the main ESTxENDS trial (NCT03589989), cigarette smokers motivated to quit smoking cigarettes will be included. Participants in the intervention group will receive an ENDS and nicotine-containing e-liquids, which they will be allowed to use ad libitum. Additionally, they will receive smoking cessation counseling. Participants in the control group will receive smoking cessation counseling only. All participants will be followed over a 24-months period. Respiratory symptoms such as chronic obstructive pulmonary disease (COPD), asthma and dyspnea will be assessed by means of questionnaires at baseline and at 6-, 12- and 24-months follow up. This trial will provide useful data on changes in respiratory symptoms in a large sample of participants.
This study evaluates frequency of exacerbations, respiratory symptoms, physical exercise intolerance and abnormal lung functions among participants who use IQOS with heatsticks compared to smokers of conventional cigarettes
