Postoperative Period

This randomized controlled clinical trial aims to evaluate the effects of an 8-week tele-yoga intervention in individuals with lung cancer who have undergone lung resection surgery. The intervention group will receive supervised yoga sessions via online synchronous video conferencing, while the control group will continue with standard post-operative care. The primary outcome is exercise capacity (6-minute walk test), with secondary outcomes including pulmonary function, respiratory and peripheral muscle strength, physical activity level, dyspnea, fatigue, sleep quality, anxiety and depression, and quality of life. It is hypothesized that tele-yoga will improve physical and psychological recovery post-surgery and may serve as a feasible home-based pulmonary rehabilitation alternative.

This study aims to develop a risk prediction model for patients who have undergone coronary revascularization (such as stent placement or bypass surgery). After these procedures, some patients still experience heart-related problems like chest pain, heart attack, or rehospitalization. This study will enroll 600 patients from multiple hospitals in China and follow them for 12 months. At enrollment and at 12, 24, 36, and 48 weeks after surgery, researchers will collect clinical information (including traditional Chinese medicine symptoms, blood tests, heart imaging) and biological samples (blood and tongue coating). Using artificial intelligence, the study will build a predictive model that combines Western medical data with traditional Chinese medicine characteristics. The goal is to better identify patients at higher risk of future heart events, so that personalized prevention and management can be provided. The study does not involve any experimental treatment or intervention - it is purely observational.

This clinical trial is designed to evaluate the accuracy, usability, and patient compliance of the Wellvii VitalDetect, an FDA-cleared (510(k) K231625), Class II medical device intended for non-invasive monitoring of vital signs including blood pressure, pulse rate, and temperature. The study will focus on comparing measurements obtained in a home environment using the device to those collected in a clinical setting, with the goal of validating the device's performance for real-world, at-home use. The Wellvii VitalDetect is a portable, battery-operated, spot-check monitor that uses finger-based technology for most parameters and an infrared sensor for forehead-based, non-contact temperature readings. It is designed for use by adults (18 years or older) in a home environment and is not intended for continuous monitoring. In addition to the cleared vital signs, the device displays other wellness parameter for general health tracking. A smartphone application supports the user experience by delivering usage instructions and data display. The study will assess: * Measurement accuracy compared to standard clinical instruments * Patient ease-of-use and engagement with the device * Adherence to regular self-monitoring schedules * Overall user satisfaction and confidence I home-based monitoring This research will contribute to the growing body of evidence supporting remote patient monitoring solutions and aims to advance the adoption of decentralized technology-enabled healthcare delivery. The study aligns with Wellvii Inc.'s mission to transform healthcare delivery by enabling continuous, connected health monitoring from the home. The ultimate goal is to empower patients and healthcare providers with real-time, clinically actionable health at a that can lead to earlier intervention, improved outcomes, and reduced system burden.

Optimal postoperative recovery after any surgical procedure requiring anesthesia is essential to achieving high-quality care. The Quality of Recovery questionnaire (QoR-15) was validated by its authors in 2013 in the study "Development and psychometric evaluation of a postoperative quality of recovery score: the QoR-15." This instrument enables a comprehensive evaluation by integrating traditional physiological measures with the patient's subjective perception of their health status. With the consent of the original author, the present study aims to validate the Romanian version of the questionnaire and adapt it to our clinical environment.

The most common cardiac surgeries are myocardial revascularization and valve replacement or plastic surgery. In the postoperative period of cardiac surgeries, the incidence of pulmonary complications ranges from 30% to 50% and is associated with increased length of hospital stay and morbidity and mortality. To reduce or minimize the occurrence of these complications, respiratory physiotherapy employs positive pressure reexpansion therapies, such as continuous positive airway pressure (CPAP) and positive pressure support with positive end-expiratory pressure (PS+PEEP). The goal of this clinical trial is to compare the effects of two positive pressure therapies, CPAP versus PS+PEEP, on the incidence of pulmonary complications in patients in the postoperative period of myocardial revascularization and valve replacement or plastic surgery, with mild to moderate pulmonary dysfunction. The main question it aims to answer is: Do patients in the immediate postoperative period of myocardial revascularization or valve replacement/plastic surgery, exhibiting mild to moderate pulmonary dysfunction, experience a comparable reversal of pulmonary conditions when treated with PS+PEEP versus CPAP? Participants will undergo the following assessments: spirometry, respiratory muscle strength testing, handgrip strength testing, and electrical impedance tomography. In the immediate postoperative period, participants will be randomized into two treatment groups: • Control Group PS+PEEP - application of 4 sets of 20 repetitions with PS to provide a tidal volume equal to 10ml/kg of predicted body weight, PEEP equal to 10 cmH2O, and inspired oxygen fraction (FiO2) to achieve peripheral oxygen saturation (SpO2) between 92-94%; • Experimental Group CPAP - application of CPAP at 10 cmH2O with FiO2 to achieve SpO2 between 92-94% for 30 minutes.
