NCT06811805
The goal of this clinical trial is to assess the effect of RenalGuard Therapy in reducing the rates of Acute Kidney Injury (AKI) within 72 hours after cardiac surgery in patients at risk of developing Cardiac Surgery Associated AKI (CSA-AKI) compared to standard-of-care (SoC). Participants will be randomized (1:1) to one of the two study groups. The Treatment study group will be managed with the RenalGuard System. The RenalGuard treatment will start after induction of anesthesiology and will run during surgery and for 6-7 hours in the Intensive Care Unit (ICU). The treatment will aim to achieve a urine rate above a predefined urine rate threshold. Patients in the control group will be managed based on the usual clinical practice in cardiac surgery centres as detailed in the recommendations for CSA-AKI prevention by accepted clinical guidelines. For both study groups general anaesthesia, cardiopulmonary bypass (CPB) run and overall patient care will be based on SoC for cardiac surgery. Patients will be followed up for up to 7 days post surgery or until discharge, which ever comes first. Long-term follow up will be performed at 90 days post surgery.
NCT06700187
Rationale: Sedentary behavior (SB) has been associated with impaired cognitive function in elderly, and negatively impacts glucose metabolism. Interrupting sitting with physical activity (PA) bouts may exert beneficial effects on cognitive function via an improved glucose metabolism. Nevertheless, the impact of breaking up prolonged sitting with various frequencies of PA bouts remains unexplored in young sedentary adults. Moreover, we hypothesize that the pattern of the breaks modifies the effects. Thus, randomized controlled trials (RCTs) are highly needed to investigate the effects of interrupting sitting with different frequencies of PA on cognitive function and glucose metabolism. We now hypothesize that interrupting sitting with different frequencies of walking breaks differentially affects cognitive function and glucose metabolism. Objective: The aim is to investigate the effects of breaking up sitting with different frequencies of PA bouts on cognitive function and glucose metabolism in young sedentary adults. Study design: A randomised, controlled cross-over study will be performed, consisting of four interventions in a counterbalanced order: uninterrupted prolonged sitting, short breaks, moderate breaks, and long breaks. Intervention: Participants will complete four conditions in a randomized, counterbalanced order: sitting (uninterrupted prolonged sitting without any interruptions), short breaks (walk 1 minute every 10 minutes), moderate breaks (walk 3 minutes every 30 minutes), and long breaks (walk 27 minutes during the intervention). Each condition lasts 4.5 hours.

Oral leukoplakia (OL) is recognized as the most common potentially malignant disorder of the oral mucosa. The pathogenesis of OL is complex and multifactorial, with oxidative stress playing a central role. Topical antioxidants have gained attention as therapeutic options to help stabilize lesions and potentially prevent malignant transformation. Both CoQ10 and curcumin have demonstrated a clinical success as strong antioxidants showing their capacity to reduce the lesion size and to stabilize the disease, ultimately preventing progression into oral malignancy. Aim: This study aims to clinically and biochemically assess the effectiveness of topical Coenzyme Q10 and Curcumin in the management of homogeneous oral leukoplakia.
NCT01917721
Kawasaki disease (KD) affects infants and young children causing inflammation of the skin and blood vessels including the coronary arteries of the heart. Despite the currently available therapy, about one third of children develop enlargement of the coronary arteries that can lead to serious complications such as coronary artery stenosis, heart attack and even death. Kawasaki disease is the most common heart disease in children in the USA and it is especially common among the children of Hawaii. Every year, 50-90 children are diagnosed with KD in Hawaii and unfortunately there is no medication available to successfully prevent coronary artery damage in a subset of cases. During the first few weeks of the illness, cells of the immune system attack the coronary arteries and release a special substance (MMP) that is responsible for the coronary artery enlargement. There is a common antibiotic, doxycycline that can specifically block the action of this special substance (MMP). Research done on animals with KD showed that doxycycline was able to block this special substance and prevent enlargement of coronary arteries. Research in adults with enlargement of the main artery in their abdomen also showed that doxycycline may improve the outcome. Based on these studies doxycycline may be a promising therapy for children with KD, who develop enlargement of the coronary arteries. The investigators' proposed research study will assess the usefulness of doxycycline in preventing the progressive enlargement of coronary arteries in children with KD. The investigators plan to perform a small (pilot) study to evaluate how good is doxycycline in preventing coronary artery enlargement. The investigators will treat 50 children with KD and enlarged coronary arteries for three weeks with doxycycline and assess the change in coronary arteries as well as the blood levels of the special substance (MMP). If doxycycline proves to be beneficial in this small study, the investigators are going to design a large research study involving multiple institutions on Hawaii and the mainland and will recruit more children to be certain about the value of the proposed treatment. The investigators' proposal may change the treatment protocol of KD and could present a possible treatment for children with enlarged coronary arteries preventing potentially devastating consequences.
NCT07323498
This randomized controlled trial examines whether imagery-based extinction memory updating following a standardized virtual reality (VR) exposure session improves the generalization of exposure effects to novel public speaking contexts. Individuals with elevated public speaking anxiety will complete a single-session VR speech exposure. Participants are randomized to (a) standard mental rehearsal of the exposure experience or (b) mental rehearsal plus guided imagery that updates the extinction memory with novel, non-exposed contexts. Generalization is assessed 7-14 days later using a multi-context behavioral approach test (BAT) in vivo and in VR.

Oral potentially malignant disorders (OPMDs) are mucosal lesions that carry a risk of malignant transformation into oral cancer. Unfortunately, a general lack of knowledge and awareness of OPMDs is common among general dental practitioners. While thorough clinical examinations coupled with biopsy can identify most OPMDs, the absence of reliable non-invasive diagnostic tools and standardized risk stratification often delays early diagnosis and treatment of oral squamous cell carcinoma (OSCC).Early detection of suspicious oral lesions is crucial for reducing OSCC-related mortality and improving patient outcomes. Histopathological assessment of biopsied tissue remains the gold standard for diagnosis. However, since biopsy is invasive and may be associated with patient discomfort; numerous noninvasive diagnostic technologies have emerged to enhance the detection and diagnosis of oral mucosal lesions.Toluidine blue (TB) staining is one such adjunctive tool, where the degree of color retention aids in lesion characterization. Dark blue staining is considered positive for lesions highly suspicious for malignancy; light blue retention is considered positive for premalignant lesions pending histopathological confirmation, while lesions showing no stain retention are classified as negative.Exfoliative cytology represents another non-invasive diagnostic approach, wherein cells obtained via brushing the oral mucosa are spread on a slide for cytological evaluation. This technique, widely accepted and increasingly utilized, has proven valuable for early cancer detection. Notably, confocal microscopy has demonstrated high sensitivity and specificity (93%) in detecting malignant cells in exfoliative cytology specimens. Currently, TB staining and confocal microscopy remain the most commonly utilized non-invasive screening techniques in clinical practice.In recent years, artificial intelligence (AI) applications have shown remarkable promise in oncology, achieving high diagnostic accuracy across various cancer types. Deep learning models, in particular, offer exceptional performance, suggesting that AI-based solutions may be feasible for widespread community screening programs following further validation. In many cases, AI models have produced diagnostic outcomes that match or surpass those of experienced pathologists. Moreover, the combined application of AI with expert human evaluation has been shown to reduce diagnostic errors and improve diagnostic precision, particularly for poorly differentiated tumors and rare cases.Several studies have been done using different AI Models and revealed a promising application of AI in diagnosing OPMDs and cancers in different body sites.

This is a Phase IIa oral cavity leukoplakia study of pioglitazone 15mg and metformin 500mg BID for 12 weeks. The primary objective is to determine the clinical and histologic changes of leukoplakia from baseline following a 12 week course of twice daily pioglitazone-metformin. Outcomes are defined as are a reduction of the leukoplakia grade in \> 50% of treated participants and a partial or complete clinical response defined as 50% or greater reduction in the sum of measured targeted lesions. In addition, participants who show clinical and histologic improvement should correlate with a significant reduction of Ki-67 proliferative indices in lesions of these participants as compared to baseline.
NCT07294859
The goal of this prospective cohort study is to evaluate the predictive value of Contrast-Enhanced Ultrasound (CEUS) and Super-Resolution Imaging (SRI) technologies regarding renal function outcomes in patients with renal cell carcinoma (RCC) undergoing partial or radical nephrectomy. The main questions it aims to answer are: Can quantitative parameters of renal microcirculation and microvascular structure derived from CEUS and SRI predict long-term renal function (defined as New Baseline eGFR for radical nephrectomy and Recovery from Ischemia for partial nephrectomy)? Can these imaging parameters accurately predict the occurrence, severity, and early recovery of postoperative acute kidney injury (AKI)? Researchers will monitor the dynamic evolution of renal blood flow and microvascular density by comparing the affected kidney to the contralateral healthy kidney before and after surgery to see if these biomarkers correlate with clinical outcomes. Participants will: Undergo CEUS and SRI examinations before surgery and at specific time points after surgery (e.g., within 7 days) to visualize renal microvasculature. Provide blood and urine samples for standard laboratory tests (such as serum creatinine and Cystatin C) to assess kidney function during hospitalization. Attend follow-up visits at 1, 3, 6, 9, and 12 months post-surgery to monitor long-term renal recovery and complete necessary imaging assessments (CT or Ultrasound).

NCT06593847
Exposure-based cognitive behavior therapy is an efficacious treatment for speech anxiety and has been delivered effectively in a virtual reality (VR) environment. The present multicenter study (conducted through the Exposure Therapy Consortium) is designed to evaluate whether trait versus state positive affectivity is a more effective predictor of exposure therapy outcomes. Further, the investigators will examine whether the predictive significance of trait positive affectivity can be accounted for by examination of baseline levels of self-efficacy, hope, and optimism.

NCT07279753
This study examined the effects of a tactical training program based on critical thinking (TPCT) on the tactical efficiency and decision-making performance of university futsal players. The intervention was designed to strengthen players' ability to interpret the dynamics of play, anticipate opponents' actions, and generate adaptive tactical responses under competitive conditions. The program followed a socio-constructivist framework, promoting learning through problem solving and interaction among teammates. Training sessions combined representative game situations, reflective questioning, and guided tactical discussions. A single-group pre-post design was implemented. Thirteen university players participated voluntarily after providing informed consent and receiving approval from the institutional ethics committee. Data were collected before and after the intervention to assess individual and collective tactical performance, goal effectiveness, and time of ball possession. The study aimed to provide evidence on the educational and performance impact of a critical thinking-based tactical approach in futsal, contributing to contemporary models of athlete development and pedagogical innovation in team sports.

A Patient Decision Aid (PtDA) is developed during a workshop in close collaboration with selected patients. The PtDA is subsequently used in the consultation between patient and physician to facilitate their shared decision on the dose of stereotactic body radiation therapy (SBRT) for lung tumors located less than 1 cm from the thoracic wall. Hypothesis: The use of a PtDA will increase the extent of Shared Decision Making (SDM) during the consultation and result in patients being more directly involved in the planning of their treatment.
NCT07167927
The goal of this pilot hybrid type I efficacy/implementation trial is to assess a newly developed decision support tool patients, parents, and providers to use during surgical treatment decision making for neuromuscular scoliosis (NMS). Results from this pilot will inform the design of a future larger effectiveness trial of the decision support tool. Participants will either receive usual care or receive the decision support tool. Researchers will assess the decision made, decision quality, individual affective, cognitive, and behavioral effects, and feasibility and acceptability of tool use. They will also collect potential barriers and facilitators to implementation and feedback about the tool and study design to maximize likelihood of successful deployment of the tool into clinical practice and inform the design of a future trial. The outcomes measures will be used to inform potential effect size estimates to inform a future trial.
