Comparison of Pulmonary Functions and Respiratory Muscle Strength Between Children With Hearing Impairment and Healthy Peers

This study aims to compare pulmonary function and respiratory muscle strength between children with hearing impairment and their healthy peers. Hearing plays a critical role not only in communication but also in cognitive, sensory, and psychomotor development. Children with hearing impairment may experience balance and coordination problems, vestibular dysfunction, and reduced muscle strength, which may negatively affect respiratory function. Although several studies have evaluated pulmonary function in children with hearing impairment, research investigating respiratory muscle strength in this population is limited. To our knowledge, no peer-reviewed study has directly compared respiratory muscle strength between children with hearing impairment and healthy controls. This study will compare spirometric parameters and respiratory muscle strength measurements between children with hearing impairment and age-matched healthy controls.

Comprehensive Multicenter Study on the Management of Acute Pain Following Thoracic Combat-Related Trauma in Ukraine

This study is a multicenter clinical trial conducted in Vinnytsia, Rivne, and Lviv, Ukraine, focusing on the management of acute pain following thoracic injuries sustained during combat. The main purpose of the study is to evaluate and compare the effectiveness and safety of two minimally invasive procedures, cryoablation and radiofrequency ablation, in controlling severe chest pain and improving patients' recovery. Cryoablation involves applying extreme cold to specific intercostal nerves to reduce pain signals, while radiofrequency ablation uses controlled heat to achieve a similar effect. Both procedures target the nerves responsible for transmitting pain from the injured areas and are performed by experienced clinicians under careful monitoring to minimize risks. Adult patients who have experienced thoracic combat trauma and are experiencing moderate to severe pain may be eligible to participate in the study if they are able to provide informed consent and comply with the study procedures. Participants will be randomly assigned to receive either cryoablation or radiofrequency ablation. Pain intensity will be assessed before the procedure, and then again at four, twenty-four, and seventy-two hours afterward using a standardized verbal numeric rating scale. In addition to measuring changes in pain, the study will monitor opioid medication use to determine whether either procedure reduces the need for pain-relieving drugs. Mechanical pain sensitivity will be evaluated using Von Frey testing, and pulmonary function will be assessed using incentive spirometry to determine whether pain reduction improves the ability to breathe deeply and cough effectively. The impact of pain on daily activities, quality of life, and emotional well-being will also be measured using validated tools such as the LANS scale, the McGill Pain Questionnaire, and the PHQ-9 depression screening questionnaire. The study aims to provide important information on the relative benefits and risks of cryoablation and radiofrequency ablation for the treatment of acute thoracic pain, including changes in pain intensity, opioid consumption, respiratory function, and overall comfort. Potential risks associated with the procedures include temporary soreness, bruising, or rare complications, but all interventions are performed under strict safety protocols. Participation in this study may allow patients to experience better pain control, potentially reduced reliance on opioid medications, and faster recovery, while contributing valuable data that could improve pain management strategies for other patients in similar circumstances. Data collected during the study will be analyzed to compare the effectiveness of the two procedures and to identify factors that may influence outcomes, such as age, body mass index, the number of intercostal levels treated, and baseline pain scores. The study provides a structured, evidence-based approach to understanding acute pain management after thoracic combat injuries and aims to support clinicians in making informed decisions to improve patient care. For patients, families, and healthcare providers, this research offers an opportunity to participate in a carefully monitored clinical trial designed to enhance recovery and reduce suffering after serious chest trauma while advancing medical knowledge in the field of pain management.

Asthma Intervention With Residential Ventilation and Air Cleaner (AIRVAC) Study

The primary goal of this study is to investigate the comparative long-term (i.e., 1-year) effectiveness of energy recovery ventilators (ERVs) and portable air cleaners (PACs) in reducing indoor air pollutants and mold levels and improving asthma-related health outcomes in inner-city children and adults with asthma in low-income households in the Dallas-Fort Worth (DFW) metropolitan area, TX. Secondary goals include: (1) examining associations among asthma outcomes, exposure to indoor air pollutants and mold, and housing-related factors, (2) conducting a cost-benefit analysis of ERV and PAC interventions for improving IAQ, mold control, and health outcomes, and (3) evaluating the utility of cost-effective methods and protocols for measuring IAQ and mold for indoor air pollution epidemiology studies and for providing practical information to patients and their physicians. Using a double-blind, placebo-controlled randomized controlled trial, 80 households will be assigned to receive active or placebo versions of ERVs or PACs. Environmental exposures and housing conditions will be monitored alongside comprehensive health assessments, including lung function tests and validated surveys on asthma control, quality of life, stress, and sleep quality.

Effect of Linvemastat in Patients With Partially Controlled Asthma (syMMPonia)

This study explores a potential new treatment for adults with moderate-to-severe asthma using a drug called linvemastat, which targets an enzyme linked to lung inflammation. Despite using standard asthma medications, many patients still struggle with symptoms, so researchers are testing whether linvemastat can improve lung function and reduce flare-ups. In a carefully controlled trial, participants receive either one of two doses of the drug or a placebo, while continuing their usual treatments. Over 16 weeks, scientists monitor breathing capacity, symptom control, and safety to determine if linvemastat could offer a meaningful new option for asthma management.

Pulmonary Function, Muscle Strength, and Functional Capacity in Minimally Invasive Cardiac Surgery

The goal of this observational study is to evaluate pulmonary function, respiratory muscle strength, peripheral muscle strength, and functional capacity in adult patients undergoing either minimally invasive cardiac surgery (via mini-thoracotomy) or conventional sternotomy for coronary artery bypass grafting (CABG) at Gülhane Training and Research Hospital.The main questions it aims to answer are: Does minimally invasive cardiac surgery preserve pulmonary function better than conventional sternotomy? Does minimally invasive cardiac surgery result in less respiratory and peripheral muscle weakness compared to conventional sternotomy? Researchers will compare patients undergoing minimally invasive surgery with those undergoing conventional sternotomy to determine differences in pulmonary function, respiratory muscle strength, peripheral muscle strength, and functional capacity. Participants will: Undergo preoperative and postoperative (day 4) assessments including spirometry, inspiratory/expiratory mouth pressure measurements, and peripheral muscle strength testing (handgrip, shoulder flexion/abduction, hip flexion, knee extension). Perform functional capacity tests (30-second sit-to-stand test, 6-minute walk test). Complete questionnaires assessing pain (McGill Pain Questionnaire) and fear of movement (Tampa Scale of Kinesiophobia).
