The purpose of this study is to determine if an indwelling catheter is more effective than surgical pleurodosis in treating malignant pleural effusion. Who is it for? You may be eligible for this study if you are an adult who is suffering from symptomatic proven pleural malignancy or an otherwise unexplained pleural effusion. Study details Consenting participants will be randomised to one of two treatment arms: * Arm 1: Indwelling pleural catheter. A long term catheter is inserted under the skin in order to allow ongoing drainage of the pleural fluid. Participants will then be instructed to undergo a daily drainage regimen for 14 days at home. * Arm 2: Surgical pleurodesis. Participants under a key-hole surgery to remove fluid and facilitate lung re-expansion. Participants will then be followed up at discharge, 14 days, monthly for 6 months and then every 3 months up to one year post-procedure. These visits will include completion of Quality of Life questionnaires, a chest xray, an ultrasound (if thought necessary) and if you are at the lead site (Sir Charles Gairdner Hospital) a review of your Actigraphy logs up to 6 months after discharge. It is hoped this research will help to provide effective symptom control with minimal intervention for those with malignant pleural effusion.

Acute respiratory insufficiency is one of the most common causes of hospitalization and death among young children. It often affects small children who, due to infections with RSV (respiratory syncytial virus), other cold viruses, or bacteria, experience difficulty breathing, rapid breathing, increased heart rate, low oxygen levels in the blood, and reduced appetite. If left untreated, a child can become exhausted, lose consciousness, and ultimately die from the condition. Children with severe acute respiratory insufficiency occupy most of the acute care beds in the pediatric wards of hospitals during the winter months. Some children are treated simply with saline inhalations, nasal saline drops, and suctioning of the nose, but many require respiratory support in the form of Continuous Positive Airway Pressure (CPAP) or high-flow oxygen therapy. In adults, it has been observed that prone positioning can improve blood oxygenation compared to supine positioning in cases of acute respiratory insufficiency. The purpose of this study is to investigate whether there are benefits or drawbacks to positioning small children admitted for difficulty breathing due to respiratory infections in a prone position instead of a supine position. The study will include a total of 40 children with acute airway disease who have been prescribed respiratory support in the form of CPAP or high-flow oxygen. The study will last a total of 2 hours and will not involve any uncomfortable procedures or pose any risks to the child. The Study Itself: Once the child has CPAP or high-flow oxygen administered via the nose, the child will be positioned for 1 hour in the prone position and 1 hour in the supine position. The order will be random and determined by lottery. A nurse will record the child's breathing in both the prone and supine positions. After the two hours, the child will be placed in the supine position, which is standard practice in the department. The child will have a pulse oximeter on both during the study and afterwards.
NCT05630092
Patients with lung disease who report breathlessness on exertion are often referred for a 6MWT. Due to the nature of the 6MWT (hereon referred to as a Max-6MWT), patients are required to walk as far as they can in 6 minutes. This may lead to an inaccurate assessment of their requirement for ambulatory oxygen as this form of exercise may not correspond to their normal daily activities. In this study, patients who are routinely referred for a Max-6MWT to investigate possible exercise-induced hypoxaemia will be invited to perform an additional walking test which is performed at their normal walking speed, referred here on in as a Nor\_6MWT. We hypothesise that performing a Nor\_6MWT will provide a more accurate assessment of a patients' oxygen requirement, primarily from their oxygen desaturation during the test.

NCT07419555
Currently, it remains unclear how to manage serial lung function measurements in a clinical setting. The investigators aimed to tackle this problem by developing a machine learning (ML) model that can accurately predict population and individual lung function trajectories. These predictions would enable the investigators to identify positive or negative deviations, thereby revealing unexpected disease patterns. A prospective validation is needed that includes data on mortality, hospitalisations, emergency-room visits and patient-reported outcomes. Within this study, the goal is to validate the ML model with the data collected from this observational study.
NCT06716502
Acute respiratory failure is a medical emergency rapidly leading to death, if not timely treated. Prompt Continuous Positive Airway Pressure (CPAP) improves patient outcomes. However, pre-hospital CPAP is currently limited to healthcare providers due to the absence of easy-to-use and immediate devices specifically designed for the non-medical population. The efficacy and usability of a new portable CPAP device will be assessed. This device is specifically designed for potential use in out-of-hospital scenarios involving acute respiratory failure. The evaluation will focus not only on the performance of the device but also on its easiness of use.
NCT05142553
This Phase IIb clinical study aims to compare the immunogenicity and safety of a booster dose of recombinant protein RBD fusion dimer vaccine as a heterologous booster (to subjects who have received the second dose of the Pfizer-BioNTech (Comirnaty) COVID-19 vaccine at least 182 days prior to the booster dose in this study) versus a homologous booster (subjects who received the second dose of the Comirnaty COVID-19 vaccine at least 182 days prior to the booster dose in this study) will receive a third dose of the Comirnaty vaccine). The extension part of the study aims to compare the immunogenicity and safety of a fourth dose of PHH-1V in subjects with a primovaccination with Pfizer-BioNTech (Comirnaty) COVID-19 vaccine plus either a booster dose of Comirnaty or PHH-1V versus those with three vaccinations of Comirnaty.
NCT05819164
The oximeter is an instrument for monitoring patients receiving oxygen therapy. It displays pulse oxygen saturation (SpO2), which is a reflection of arterial oxygen saturation (SaO2). An accurate SpO2 value is essential for optimal management of the O2 flow delivered to patients. Several factors can influence this measurement and the choice of ventilatory support: the type of oximeter used, skin pigmentation and the oxygenation goal. The objective of our study is to evaluate the impact of the oxygenation goal and the oximeter used on oxygen flows in patients with COPD (or with hypercapnia, or at risk of hypercapnia) and in patients without COPD (in particular pneumonia, pulmonary fibrosis and other pathologies) Our hypothesis is that the SpO2 target and oximeter used will have an impact on oxygen flows and that these effects will be synergistic in these different populations.

Arterial puncture for blood gas analysis is a diagnostic procedure used to assess arterial blood gases and monitor a patient's oxygenation status. It is widely regarded by nursing staff as one of the most painful routine procedures. Despite this, the use of local anesthesia prior to arterial puncture remains uncommon in clinical practice. Several types of anesthetic agents and administration techniques have been evaluated, with mixed results regarding their effectiveness in reducing patient-reported pain. Studies comparing subcutaneous lidocaine injection or ethyl chloride spray to no analgesic intervention have shown that ethyl chloride does not significantly reduce pain. Moreover, the discomfort caused by lidocaine injection appears to be comparable to that of the arterial puncture itself, suggesting limited overall benefit from this approach. Other investigations have similarly reported a lack of significant pain reduction with ethyl chloride spray, although some contradictory findings exist. Ultrasound-guided arterial puncture has been shown to improve success rates and shorten procedure duration; however, it does not appear to influence pain perception. The impact of needle size on pain intensity has also been explored, with conflicting results. Some studies found no significant difference in pain when using different gauge needles, while others reported reduced pain with the use of finer needles, such as insulin needles, compared to standard arterial puncture needles. Topical anesthetic creams combining lidocaine and prilocaine have been assessed in randomized, double-blind trials. These studies found no significant difference between anesthetic and placebo groups in terms of pain intensity or the proportion of painful procedures. More recently, cryotherapy has been investigated as a non-pharmacological method to reduce pain prior to arterial puncture. Several randomized controlled trials using varying cryotherapy protocols have generally reported a significant reduction in pain compared to control groups, with longer application times appearing to enhance effectiveness. However, these findings must be interpreted with caution due to methodological limitations. In some studies, sample size calculations were not justified, randomization procedures were poorly described, and reported pain levels were unusually high compared to those typically observed in European populations, raising concerns about external validity. In certain cases, although pain reduction was statistically significant, it did not reach the minimal clinically important difference, limiting its clinical relevance. Conversely, other trials reported very low pain scores following cryotherapy, suggesting a substantial clinical benefit. The short application time required for cryotherapy also makes it far more practical than topical anesthetic creams, which require prolonged application. This practicality supports its use in both emergency and outpatient settings. Some authors have noted that blinding is challenging when using cryotherapy and have suggested incorporating placebo interventions in future studies to improve methodological rigor. Overall, systematic analyses indicate that cryotherapy appears to be a safe and potentially effective method for reducing pain during arterial puncture. Nevertheless, the existing evidence is limited by a high risk of bias, underscoring the need for further high-quality randomized controlled trials. Conclusion: Given the promising but methodologically constrained evidence, there is a strong justification for conducting a rigorously designed, placebo-controlled randomized trial to accurately assess the effectiveness of cryotherapy in reducing pain associated with radial arterial puncture.

NCT06065176
The purpose of this research study is to find out how well two different 2023-2024 updated COVID-19 vaccines protect people from COVID-19 (the disease caused by the SARS-CoV-2 virus), and to determine if getting a 2023-2024 updated vaccine provides better protection from COVID-19 than not getting a vaccine. If the participant chooses to get a 2023-2024 updated COVID-19 vaccine as part of this study, they will have a 50/50 chance of receiving either the Novavax or Pfizer mRNA vaccine. If the participant decides not to get a 2023-2024 updated COVID-19 vaccine, the participant can still participate in other study activities. STUDY ACTIVITIES: * An online enrollment survey * An in-person enrollment visit * Weekly online surveys for 20 weeks * Weekly COVID-19 tests for 20 weeks * Additional online surveys if you have COVID-19 symptoms or tested positive for COVID-19. * Additional COVID-19 tests if you have COVID-19 symptoms or tested positive. * Online survey questions in the middle and at the end of the study
NCT06796894
The aim of this study is to determine the level of respiratory dysfunction, symptoms and frailty in patients with asthma according to different endophenotypes (allergic and eosonophilic asthma). In the light of the data obtained, it is thought that rehabilitation approaches that can be determined according to different endophenotypes in line with the evaluated parameters will guide health professionals working in this field. Hypotheses H0: There is no difference between allergic and eosonophilic asthmatics in terms of pulmonary function, respiratory dysfunction, symptoms, dyspnoea, fatigue, rhinitis, perception of breathlessness in activities of daily living, asthma control, level of frailty or quality of life. H1: There is a difference between individuals with allergic and eosonophilic asthma in terms of pulmonary function, respiratory dysfunction, symptoms, dyspnoea, fatigue, rhinitis, perception of breathlessness in activities of daily living, asthma control, level of frailty or quality of life.

The overarching hypothesis of this proposal is that IL-5 acts on multiple sinus tissue cell types, including plasma cells and epithelial cells, to promote immune dysregulation, and that inhibition of IL-5 affects several relevant effector pathways that lead to clinical benefit.
NCT06691971
Respiratory signs and symptoms consisting of wheeze, cough, and breathlessness are obtained in a manual fashion through history taking and physical examination by the healthcare professional. Auscultation of the lung assesses airflow through the trachea-bronchial tree and is helpful in diagnosing various respiratory disorders. AeviceMD is a wearable device that can acquire and process lung sounds, thus assisting in the detection of abnormal lung sounds. The primary objective of this study is to determine if AeviceMD can detect wheeze of pediatrics and adults as accurately as a physician through auscultation. The secondary objective is to investigate if AeviceMD can be used for remote auscultation of breath sounds.

Vapendavir (VPV) is a drug being developed to treat human rhinovirus (RV) infection, one virus responsible for the common cold. Vapendavir prevents the virus from entering cells and making more infectious copies of itself. A study is being planned to investigate VPV in patients with chronic obstructive pulmonary disease (COPD, a lung disease making it difficult to breathe) who develop a rhinoviral infection; however, VPV has not been approved for use in treating any indication (disease) by the FDA or any other global regulatory agency. Therefore, VPV is considered investigational, and the study doctor is conducting this investigational research study. Safety will be monitored throughout the entire study.

The sequelae that occur in post-COVID-19 patients are multiple and, at a therapeutic level, these represent a new challenge within the general context of the pandemic that the world is suffering. The virus has managed to end thousands of lives today and many other cases are being charged as directly responsible for a multiplicity of multisystem damages that need to be diagnosed and treated. Among the most relevant, are those that can affect to respiratory levels in patients without previous pahologies, and in patients at risk who already had a pathology prior to infection. On the other hand, signs and symptoms have been observed characteristic in the organ systems described above in post-contagion patients, directly associated with sequelae SARV-CoV2. The radiofrequency (RF) of electromagnetic waves represents a technology of proven efficacy and safety in multiple fields of both human and veterinary medicine. These include neurological pathologies, respiratory disease and very especially those that affect the locomotor system. In therapeutics there are different RF modalities depending on the modality, polarity, type of signal and frequency, which in turn translate into different therapeutic profiles, clinical indications, efficacy and safety. Among the RF technologies most used today and that have a greater scientific background, is the one known as Resistive Capacitive Monopolar RadioFrequency at 448 kHz (INDIBA®) (RFMCR). This study aims to assess the efficacy and safety of RFMCR in the treatment of respiratory sequelae in patients presenting this type of pathologies that appear after contagion by COVID-19. Through this non-invasive technique, the investigators want to show that RF can help the physical rehabilitation of these patients through metabolic stimulation, increased vascularization and oxygenation of directly affected tissues, effects of deep hyperthermia generated by the interaction of the current with the treated biological substrate, as well as the activationof tissue regeneration, the result of subthermal action. It is thus intended to improve signs such as lung capacity, dyspnea, neuropathies and global muscle capacity, which are essential for the recovery of the post-COVID-19 patients. The hypothesis of this study is that current post-COVID-19 treatments can be significantly improved in order to prevent complications and ensure the patients' well-being.

NCT06839963
Study team will perform a prospective, observational study in two sites in the Democratic Republic of Congo (DRC) and Bangladesh in children aged 3 months to 14 years, admitted to hospital with acute respiratory symptoms. The Kinshasa lung ultrasound (K-LUS) approach integrates existing WHO clinical guidelines, lung ultrasound diagnostic accuracy evidence and paediatric ultrasound guidelines. The approach was built using a modified Delphi technique and integrates six LUS profiles, two clinical history features (timing of onset, trauma) and one clinical examination feature (fever) to suggest one among 10 clinical diagnosis. After the initial diagnosis is established by the treating physician, a research assistant will perform a LUS examination and apply the K-LUS approach. Comparison between the K-LUS derived diagnosis and the clinical diagnosis will be performed. After patient discharge a panel will also establish the most likely diagnosis according to all information available during patient stay. This study is funded by the Wellcome Trust (ITPA grant) ref: WT-ITPA 2021/001

Face masks have become a critically important public health intervention after the COVID-19 pandemic. Multiple types of masks ranging from full face filtering to cloth masks have been developed and commercialized to facilitate protection against respiratory pathogens. Most of these systems are made with opaque fabrics and may prevent individuals from expressing emotions or for those who are deaf and hard of hearing, communicating. To date, few transparent face masks which also confer respiratory pathogen protection have been developed. This study will test the feasability and acceptability of two new masks, the SEEUS-95 mask and CrystalGuard mask which are both transparent versions of N-95 filtering face masks.
