This clinical trial investigates new treatment approaches for chronic thromboembolic pulmonary hypertension (CTEPH), a condition affecting the lungs' blood vessels. CTEPH often develops after repeated blood clots in the lungs, leading to increased pressure and strain on the heart. The study aims to assess the effectiveness of combining two treatments, balloon pulmonary angioplasty (BPA) and pulmonary artery denervation (PADN), in reducing blood pressure in the lungs compared to the standard treatment. Additionally, the trial will explore the impact of these treatments on patients' quality of life. The hope is to improve outcomes and provide valuable insights into managing this challenging condition.
Patients undergoing general anesthesia will have an endotracheal tube inserted. Adequate muscle strength recovery in the recovery room is crucial to ensure before extubation. One of the criteria we use to determine the recovery of muscle strength post-use of muscle relaxants in conditions without specific monitoring devices is the ability to maintain body oxygen levels without oxygen assistance for 3 minutes. This study aims to determine the muscle strength value in the recovery room using extubation strategies without muscle strength monitoring compared to extubation strategies with muscle strength monitoring.
How does one know what to look at in a scene? Imagine a "Where's Waldo" game - it's challenging to find Waldo because there are many 'salient' locations in the picture, each vying for one's attention. One can only attend to a small location on the picture at a given moment, so to find Waldo, one needs to direct their attention to different locations. One prominent theory about how one accomplishes this claims that important locations are identified based on distinct feature types (for example, motion or color), with locations most unique compared to the background most likely to be attended. An important component of this theory is that individual feature dimensions (again, color or motion) are computed within their own 'feature maps', which are thought to be implemented in specific brain regions. However, whether and how specific brain regions contribute to these feature maps remains unknown. The goal of this study is to determine how brain regions that respond strongly to different feature types (color and motion) and which encode spatial locations of visual stimuli transform 'feature dimension maps' based on stimulus properties as a function of task instructions. The investigators hypothesize that feature-selective brain regions act as neural feature dimension maps, and thus encode representations of relevant location(s) based on their preferred feature dimension, such that the stimulus representation in the most relevant feature map is up-regulated to support adaptive behavior. The investigators will scan healthy human participants using functional MRI (fMRI) in a repeated-measures design while they view visual stimuli made relevant based on a cued feature dimension (e.g., color or motion). The investigators will employ state-of-the-art multivariate analysis techniques that allow them to reconstruct an 'image' of the stimulus representation encoded by each brain region to dissect how neural tissue identifies salient locations. Each participant will perform a challenging discrimination task based on the cued feature (report motion direction or color of stimulus dots) of a stimulus presented in the periphery, which are identical across trial types. Across trials the investigators will manipulate the attended feature value (color, motion, or fixation point). This manipulation will help the investigators fully understand these critical relevance computations in the healthy human visual system.
Pulse oximetry, or SpO2, is a vital sign used across healthcare systems to gauge how much oxygen blood is carrying as a percentage of the maximum it could carry. Recent research has suggested that current SpO2 monitors may inaccurately report high SpO2 in patients with darker skin tones when the actual oxygenation is at unsafe, low levels. Additionally, this new research suggests as the SpO2 levels decrease, the risk of occult hypoxia rises. The investigators hypothesize melanin interferes with the pulse oximetry accuracy. Investigators will use spectrophotometry to measure melanin indices and other variables to test this hypothesis.
The goal of the research study is to increase teachers' implementation of evidence-based practices in Early Head Start classrooms through the delivery of a professional development (PD) training intervention. The main questions that the study aims to answer are: 1. Does teacher participation in a PD intervention improve the use of evidence-based practices from pre- to posttest? 2. To what extent is the PD intervention feasible to implement in an established child care program? 3. To what extent is the PD program acceptable to teachers? Participants will attend PD workshops and participate in content-related job-embedded coaching sessions during the implementation of the study.
Collect data on various wound treatments and their related wound healing process, in real life settings. Analyze the safety and efficacy of wound treatments, including: advanced biological/synthetic grafts and standard of wound care treatments.
Regular physical activity (PA) promotes benefits for both physical and mental health. Among the numerous PA's with a collective nature that can add to the existing recommendations, combat sports training interventions are viable alternatives since they integrate benefits in different aspects for health. In this way, capoeira can be a strategy for the prescription of exercise, aiming to serve participants collectively and maintaining the adherence of this practitioner to the intervention. However, little is known about this issue. So, the aim of the present study is to verify the effect of 12 weeks of capoeira training on the physical performance and psychological aspects of previously physically inactive adults.
The transversus abdominis plane (TAP) block, whereby local anesthetic is injected between the internal oblique and transversus abdominis fascia to facilitate blockade of somatic afferents nerves, is an effective, non-narcotic adjunct incorporated into many ERAS protocols. We hypothesized that surgeon delivered LAP-TAPs would be non-inferior to anesthesia-delivered US-TAPs in terms of post-operative pain control
Diphenhydramine has H1-antihistamine action, it also possesses anti-muscarinic properties. Thus, diphenhydramine might be able to reduce the problem of catheter related bladder discomfort by inhibiting smooth muscle spasm of the urinary bladder via its anti-muscarinic action .
The goal of this observational study is to evaluate the effectiveness and safety of the Integrity bio-inductive implant in treating partial and full thickness rotator cuff tears. The main questions it aims to answer are: - How does the application of the Integrity implant affect patient-reported outcome measures (PROMs) such as ASES, SANE, and PROMIS? - What are the imaging characteristics of the rotator cuff tears at 3 and 6 months postoperatively when using the Integrity implant? Postoperative MRIs will be obtained from 10 consecutive patients who have undergone rotator cuff repair using the Integrity implant at 3 and 6 months after surgery. Participants include those with partial and full thickness tears treated with different surgical techniques involving the implant. They may receive either isolated onlay use of the graft for partial tears or augmentation of a standard single or double row repair with the graft applied to the superior surface of the repair.
