NCT07319416
Neuroendocrine tumors (NETs) are a wide group of neoplasms arising from the diffuse neuroendocrine cell system that features significant molecular and biological heterogeneity. They mainly derive from the enterochromaffin cells of the gastroenteropancreatic tract (GEP-NETs) and their incidence and prevalence are steadily rising, possibly as a consequence of improving diagnostic methods and earlier detection. A major feature of GEP-NETs is their somatostatin receptor (SSTR) immunogenicity, which is relevant both for diagnostic and therapeutic purposes. For patients with unresectable or advanced disease, systemic treatment is the standard of care. In this setting, Somatostatin analogues (SSAs) are the standard first line therapy and, even if response rates are low, disease progression is halted in about two thirds of patient. Recently, targeted radionuclide therapy has claimed significant attention as a valuable treatment option for many solid neoplasms. This approach relies on the administration of a radionuclide linked to a carrier-molecule that selectively interacts with tumor associated antigens, being eventually internalized and releasing β-radiation emission and low-energy γ rays directly from the inside of the cancer cells. Peptide Receptor Radionuclide Therapy (PRRT) is strongly recommended in progressive metastatic/inoperable pretreated NETs that showed homogenous SSTRs expression by SSA positive PET-CT or single photon emission computed tomography (SPECT) imaging. Although PRRT is effective in the majority of cases, approximately 15-30% of patients will eventually progress during treatment. It is still challenging to distinguish potential responders versus non-responder patients. The identification of predictive biomarkers, apart from the required expression of somatostatin receptors, and of non-invasive diagnostic predictive exams, are an unmet need. Despite the promising clinical results, very little is known about the biological changes induced by PRRT on cancer tissue and tumor microenvironment and vascularization. The assessment of treatment' response therefore still relies on CT and PET-CT as markers of tumoral activity. Among imaging modalities, ultrasound could play a key role in this setting. Indeed, contrast-enhanced ultrasound (CEUS) allows a thorough assessment of tumor perfusion through analysis of both contrast media flow pattern and time-intensity curves. This quantitative analysis, called dynamic contrast enhanced ultrasound (DCE-US) is a novel technique that estimates tissue perfusion based on phase-specific enhancement after the injection of microbubble contrast agents. The parameters derived from this analysis could be used for treatment monitoring in oncology, as they are easily comparable through time in each patient. In order to establish the bases for standardization of DCE-US, the European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB) recently published an update on this topic.
NCT05209035
Alzheimer's disease (AD) is a progressive and multifactorial neurodegenerative disease. Before progressing to AD, individuals may experience mild cognitive impairment (MCI). While these individuals with MCI have an increased risk of progressing to AD, emerging studies reveal that obstructive sleep apnea (OSA) is a risk factor for both MCI an well as AD. Thus, it is worthwhile to identify clinical management or interventions that retard the conversion of subjects with comorbid MCI and OSA and AD. A randomized, double-blind, placebo-controlled study proposed herein aims to examine the effect of trazodone on reducing level sST2 and protein markers that are associated with neurodegeneration in the plasma of subjects with comorbid OSA and MCI. In this 1-year study, 124 study participants will undergo a series of neurocognitive assessments.
NCT06526559
The main goals of this trial is to study the feasibility and safety of using barbed sutures compared to the conventional PGA (Polyglactin) sutures in minimally invasive dismembered pyeloplasty. The main questions in using barbed sutures would be: 1. Is it safe with similar post-operative outcomes? 2. Does it have any significant complications? 3. Is it easier to handle intra-operatively?
NCT05050500
Dapagliflozin is one of the SGLT-2 inhibiters. Recent clinical trials have demonstrated that SGLT-2 inhibitors are effective for treating heart failure. The DAPA-HF clinical trial has demonstrated that the effects of empagliflozin and dapagliflozin improve renal outcomes and reduce all-cause and cardiovascular death in patients with HFrEF\[1\]. However, its effect on myocardial infarction, the most common disease leading to death in the population, has not been evaluated sufficiently. A meta-analysis has demonstrated that compared with the control, SGLT2 inhibitor is associated with a reduction in the incidence of major adverse cardiovascular events (MACEs), myocardial infarction, cardiovascular mortality and all-cause mortality\[2\]. It seems that dapagliflozin might be effective for patients with acute myocardial infarction based on these studies. Thus, this study aims to evaluate the effect of dapagliflozin on short-term prognosis in patients with acute myocardial infarction compared to placebo. 1.

NCT07317674
Labor induction rates have increased substantially worldwide, and successful cervical ripening remains a key determinant of induction outcomes. Mechanical cervical ripening with a Foley balloon catheter is widely used and considered safe, while nipple stimulation promotes endogenous oxytocin release and represents a physiologic method for stimulating uterine contractions. However, the combined effect of nipple stimulation and balloon catheter use has not been systematically evaluated. This prospective, randomized, double-blinded controlled trial will assess whether the addition of nipple stimulation to Foley balloon catheter cervical ripening improves Bishop score and shortens the induction-to-delivery interval compared with balloon catheter alone. Term pregnant patients (37-42 weeks' gestation) with a singleton, cephalic pregnancy and an unfavorable cervix (Bishop score \<6) requiring labor induction will be randomized to receive either Foley balloon catheter plus standardized nipple stimulation or Foley balloon catheter alone. The primary outcomes are change in Bishop score after catheter removal and time from catheter insertion to delivery. Secondary outcomes include need for additional induction methods, mode of delivery, maternal and neonatal outcomes, pain, patient satisfaction, and breastfeeding rates. The study aims to evaluate the efficacy and safety of incorporating a physiologic intervention into standard mechanical cervical ripening.
NCT07075809
The goal of this clinical trial is to evaluate if laserpuncture (laser acupuncture) can reduce leucopenia caused by chemotherapy and improve the quality of life in patients with head and neck cancer. The main questions it aims to answer are: * Does laserpuncture reduce the incidence of chemotherapy-induced Leucopenia ? * Does laserpuncture improve quality of life in these patients? Researchers will compare patients receiving laserpuncture therapy to a control group receiving sham laserpuncture to see if the intervention has a beneficial effect. Participants will: * Undergo six sessions of laserpunktur or sham laserpuncture during chemotherapy * Have leukocyte counts and absolute neutrophil counts measured before and 7-14 days after chemotherapy * Complete quality of life assessments using EORTC QLQ-C30 and EORTC QLQ-H\&N35 questionnaires

NCT07231796
This study looks at how well a medicine called naldemedine works for people with cancer who become constipated while taking opioids. Opioids are medications prescribed to treat persistent or severe pain. Opioids can slow down the bowel and make it hard to pass stool. About 6 out of 10 people who use opioids have constipation. Laxatives such as lactulose or macrogol are described to help with this problem. If laxatives do not work, doctors may use special medicines called opioid blockers that act only in the gut. These medicines help relieve constipation without reducing pain relief. Naldemedine is one of these opioid blockers. It became available in the Netherlands in 2024 but is not yet widely used. The goal of this study is to learn how well naldemedine works in everyday care and how people feel while using it. Researchers will collect information on both medical results and participants' experiences.
NCT07176442
This randomized controlled trial will compare three innovative teaching methods-Massive Open Online Courses (MOOCs), simulation, and escape games-among newly recruited medical interns at Ibn Sina University Hospital in Rabat, Morocco. The study aims to evaluate their effectiveness in improving knowledge of diabetic ketoacidosis management, retention of knowledge after 4 weeks, and learner motivation. Fifty-one interns will be randomly assigned to one of the three groups. Outcomes will be assessed using multiple-choice knowledge tests at baseline, immediately after training, and 4 weeks later, as well as the Intrinsic Motivation Inventory questionnaire. The results will provide evidence on the most effective and engaging approach to support induction training of new medical interns.
NCT07314229
Cystic fibrosis is a genetic disorder affecting the entire body and associated with respiratory exacerbations, impaired quality of life and reduced life expectancy. The therapeutic management of cystic fibrosis has been profoundly changed by the recent arrival of a combination of highly effective cystic fibrosis transmembrane conductance regulator (CFTR) modulators, Elexacaftor-Tezacaftor-Ivacaftor (ETI), which improve quality of life, respiratory function and reducing the number of exacerbations. The impact of these treatments on exercise adaptation has not been clearly identified. The main objective is to estimate the prevalence of ventilatory reserve amputation during submaximal exercise testing assessed by the 6-minute walk test (6MWT) in patients with cystic fibrosis treated with ETIs.
NCT06758180
Adult Basic Life Support (BLS) is a critical skill in emergency situations. Teaching this skill effectively to students in first aid and emergency aid programs is essential for imparting both theoretical knowledge and practical competencies. Educational methods have a direct impact on students' knowledge levels and skill acquisition. In addition to traditional teaching methods, advancements in educational technology have introduced innovative approaches such as interactive video games into this field. This study compares the effects of two different instructional methods-video-assisted education and interactive video game-supported education-on students' learning outcomes and practical performance in adult BLS training.

NCT06900179
Malignant fungating wounds (MFWs) affect 5-14% of patients with advanced cancer, making them a common complication in this population. Characterized by symptoms such as foul odor, heavy exudate, bleeding, moderate to severe pain, and infection, MFWs cause significant physical discomfort and pose life-threatening risks while also leading to profound psychosocial issues, including shame and social isolation. These factors severely impact patients' quality of life, with half of those diagnosed surviving only six months on average. However, clinical nursing staff often lack adequate knowledge and skills in managing MFWs, with an average accuracy rate of just 56.5%. Notable deficiencies exist in areas such as wound disinfection, odor control, and wound assessment, directly affecting the quality of patient care and highlighting an urgent need for specialized MFW training. Traditional MFW education often lacks real-life clinical scenarios and hands-on practice, resulting in a gap between learning and application and leaving learners ill-prepared for the complexities of clinical settings. In contrast, augmented reality (AR) technology presents new possibilities for nursing education. AR can create highly simulated clinical environments where learners can safely practice complex clinical skills, enhancing clinical decision-making abilities. The implementation of AR-based training programs provides nursing staff with a more realistic and effective learning experience, allowing them to better address the challenges posed by MFWs and ultimately contributing to improvements in patient care and quality of life.
NCT07312656
Radiation-induced oral mucositis (RIOM) is an inevitable acute complication in radiotherapy for head and neck malignancies, characterized by a complex pathogenesis involving multiple biological processes. According to the latest data from the International Agency for Research on Cancer (IARC), approximately 650,000 new cases of head and neck cancers are diagnosed globally each year, with about 70% of patients undergoing radiotherapy. RIOM develops through a multistep pathophysiological cascade, including initiation of mucosal injury, signaling amplification, inflammatory response, ulceration, and eventual healing. Ionizing radiation induces DNA damage in oral mucosal epithelial cells, triggering increased apoptosis. This cellular injury promotes the activation and release of pro-inflammatory mediators such as tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6), compromising the integrity of the mucosal barrier and ultimately leading to ulcer formation. Current clinical management of RIOM remains largely supportive, relying on oral hygiene, nutritional supplementation, and pain control, with no effective prophylactic agents available. Despite extensive research into potential interventions internationally, no drugs specifically approved by the FDA or NMPA for the prevention of RIOM have reached the market. This significant unmet clinical need calls for urgent scientific and therapeutic advancement. This study aims to evaluate the therapeutic efficacy and safety profile of aerosolized exosomes derived from mesenchymal stem cells in the prevention and treatment of radiation-induced oral mucositis in patients receiving radiotherapy for head and neck cancers. The ultimate objective is to establish a novel and effective therapeutic strategy for clinical application.
NCT07303504
Background: This article presents the protocol for a randomised controlled trial designed to develop and evaluate a psychoeducational intervention aimed at preparing high-performance athletes for the challenges and opportunities presented by the transition to retirement from sport. The protocol was developed through a literature review and consultations with experts in sports psychology and career transition. Methods: The study will be conducted at the Faculty of Psychology of the University of Salamanca (Spain). High-performance athletes aged 30 or older who are close to retirement or who have retired in the last five years will be recruited. Participants will be randomly assigned to two groups: the intervention group, which will undergo a psychoeducational programme consisting of 12 sessions over 3 months; and the control group, which will receive a minimum educational programme of one session. All participants will complete initial and final assessments, as well as a 3-month follow-up, collecting sociodemographic data and applying various psychological, social and health assessment instruments. Discussion: This protocol describes a comprehensive psychoeducational intervention aimed at improving quality of life and attitudes towards retirement from sport, increasing life satisfaction, psychological flexibility, perceived social support, general health, self-efficacy and self-regulation, and reducing negative stereotypes associated with the end of a sporting career. The evidence generated will guide future interventions, policies, and educational programmes to promote a healthy, active, and satisfying transition to the post-sport stage.
