NCT04579380
This trial studies how well tucatinib works for solid tumors that make either more HER2 or a different type of HER2 than usual (HER2 alterations) The solid tumors studied in this trial have either spread to other parts of the body (metastatic) or cannot be removed completely with surgery (unresectable). All participants will get both tucatinib and trastuzumab. People with hormone-receptor positive breast cancer will also get a drug called fulvestrant. The trial will also look at what side effects happen. A side effect is anything a drug does besides treating cancer.

In our study, it was aimed to show the contribution of intraoperative intravenous magnesium sulfate administration to peroperative opioid consumption and postoperative analgesia.
NCT05465343
This study is a single-arm, open-label, prospective phase II trial. The aim of this phase II study is to evaluate the efficacy and safety of Furmonertinib in patients with EGFR mutation (including 19del or 21L858R or T790M) in advanced NSCLC with brain metastases.
NCT06494423
This is a feasibility study of a Work Support (WorkS) intervention designed to ameliorate employment challenges for people preparing to return to work after allogeneic stem cell transplantation. The aim of this study is to evaluate "proof of concept" by: 1. examining the feasibility and acceptability of the WorkS intervention and the study procedures, and 2. exploring the preliminary effects of WorkS for improving patient-reported return-to-work self-efficacy, work status, quality of life, and financial toxicity.
NCT05093933
The purpose of this study is to evaluate the efficacy and safety of vericiguat in participants with chronic heart failure with reduced ejection fraction (HFrEF), specifically those with symptomatic chronic HFrEF who have not had a recent hospitalization for heart failure or need for outpatient intravenous (IV) diuretics. The primary hypothesis is that vericiguat is superior to placebo in reducing the risk of cardiovascular death or heart failure hospitalization.
NCT06703281
The interscalene block (ISB) is one of the peripheral nerve blocks providing surgical anesthesia and postoperative analgesia in shoulder arthroscopy, eliminating the need for general anesthesia. It is performed by administering local anesthetics (LA) to the C5-C6 roots between the scalene muscles at the level of the cricoid cartilage. ISB-related side effects, such as diaphragmatic paralysis, can occur with the spread of LA to the phrenic nerve over the anterior scalene muscle. To prevent this, a superior trunk block (STB) can be performed by administering LA close to the supraclavicular region where the C5-C6 roots merge into the superior trunk (further away from the phrenic nerve). Although there are studies in the literature demonstrating diaphragmatic paralysis using ultrasound and/or spirometry, no study evaluating diaphragmatic paralysis simultaneously with both ultrasound and spirometry under regional anesthesia alone has been found. Therefore, in this study, the investigators aim to assess the effects of this side effect on diaphragmatic excursion using ultrasound simultaneously and on respiratory functions using spirometry.
NCT06797973
The goal of this clinical trial is to learn if morphine added to the spinal anaesthesia can improve postoperative pain treatment for patients undergoing caesarean section, without increasing the risk of serious adverse events in mother and baby. The main questions it aims to answer are: * Is the treatment effective in preventing postoperative pain? * Is the treatment safe for both mother and baby? Participants will be given a normal spinal anaesthesia with addition of either morphine or sodium chloride (inactive substance). All participants will receive standard postoperative pain treatment, including morphine tablets as needed. Researchers will collect data from the electronic medical record and ask the participants to fill out questionnaires about pain levels and possible side effects.
NCT06919094
Reminiscence therapy is a non-invasive, non-pharmacological intervention that has been shown to improve cognition, mood, functional status, quality of life, and apathy in older adults. Group reminiscence therapy combines structured social engagement and recounting of personal stories that address both social connection (a risk factor for cognitive decline) and cognition. Life story club© (LSC) is an established, non-profit organization that provides virtual, group reminiscence therapy for older adults to reduce loneliness and promote a sense of belonging and has not been formally studied.
NCT04439552
Evaluation of neuroplasticity of pain pathways and corneal afferent nerve regeneration following corneal crosslinking (CXL) in keratoconus patients using fMRI and corneal In Vivo Confocal Microscopy (IVCM).
NCT06752850
The rationale for conducting this open-label phase 4 study is to assess whether once-weekly prophylaxis with efanesoctocog alfa (50 IU/kg) improves the disease course of existing synovial hypertrophy and prevents the risk of joint bleeds in patients with moderate or severe haemophilia A. The use of imaging assessments will allow for objective detection and monitoring of synovial hypertrophy, and thus expand on the previous findings demonstrating positive effects of once-weekly prophylaxis with efanesoctocog alfa (50 IU/kg) on joint health.
NCT07130123
The aim of this clinical trial is to evaluate endotracheal suctioning during positive pressure extubation in mechanically ventilated adult patients (over 18 years old) in the intensive care unit (ICU). The main question it aims to answer is whether the intervention improves the respiratory oxygenation index (ROX) three hours after extubation compared to no endotracheal suction during positive pressure extubation. Participants will only need to be extubated by the nursing team in the ICU. Follow-up will consist of evaluating respiratory rate, pulse oximetry and inspired oxygen fraction for three hours following extubation.
NCT07294547
Opportunistic CMV viremia (primary infection or reactivation) is usually managed by taking prophylactic medication for both adult and pediatric kidney transplant patients. Most hospitals prescribe valganciclovir for this purpose but valacyclovir has also been used. The most unfavorable side effect of valganciclovir is bone marrow suppression which can be troublesome for kidney transplant patients who are already immunosuppressed. We aim to assess the non-inferiority of valacyclovir compared with valganciclovir in this study.
NCT07244991
Background This study is part of a doctoral research project at Universidad Cardenal Herrera CEU (Spain), directed by Prof. Santiago Arias de Luxán and conducted by doctoral candidate Shirli Kelmendi within the PhD program in Translational Medicine. Fixed orthodontic appliances complicate oral hygiene by creating retention areas that favor bacterial colonization and alter microbial balance. These conditions increase plaque accumulation and Streptococcus mutans (S. mutans) proliferation in saliva and plaque. The frequent low-pH environment favors aciduric bacteria such as S. mutans and lactobacilli, promoting enamel demineralization and formation of white spot lesions (WSLs) or cavitations. WSLs appear as opaque white areas due to subsurface mineral loss, mainly in the gingival third of the crown. They may develop as early as one month after bracket placement, while in patients without appliances, progression occurs after at least six months. Increased S. mutans levels have been reported as early as six weeks after treatment start. Risk factors include poor brushing, lack of floss or rinse use, time since last cleaning, and presence of caries or lesions. Intervention MI Paste Plus (GC, Japan) is a remineralizing cream with 0.20% sodium fluoride (900 ppm) and 10% CPP-ACP (RECALDENT™), providing calcium and phosphate stabilized by casein phosphopeptides. It has antibacterial and remineralizing effects, suitable during or after orthodontic treatment to prevent or reduce WSLs. Objective To evaluate whether MI Paste Plus during fixed orthodontic treatment reduces S. mutans counts in saliva and/or WSL incidence. Study Design A prospective, triple-blind, randomized clinical trial, approved by the Ethics Committee of the Ministry of Health of Albania and the Ethics Committee for Human Research of Universidad Cardenal Herrera CEU, Spain. The study will include 200 patients (100 per group) from two orthodontic clinics in Tirana, Albania. Participants will be stratified by age, risk level, and appliance type, then randomized by third parties. Outcome Measures Primary variables: S. mutans counts in saliva and number of WSLs after 3 months. Standardized saliva collection, culturing, and bacterial quantification ensure consistency. Clinical assessments will be performed at 1 and 3 months using QRay Cam Pro (Inspektor Systems, Netherlands) for quantitative fluorescence and ICDAS for visual inspection. Data will be analyzed using SPSS/R Commander software.
NCT07277790
The Cincinnati Prehospital Stroke Scale (CPSS) is traditionally scored directly by a healthcare professional or a layperson who independently observes facial droop, arm weakness, and speech disturbance, constituting the primary CPSS score. In contrast, this study focuses on witness-derived secondary CPSS scoring, which is performed indirectly by an emergency physician who is blinded to the patient's physical examination findings and relies exclusively on symptom descriptions provided by witnesses of the patient's initial presentation. This prospective analytical cross-sectional study aims to evaluate the predictive accuracy of secondary CPSS scores obtained by emergency physicians through structured interviews with witnesses of suspected stroke cases. Interrater reliability will be assessed between secondary CPSS scores independently assigned by a senior emergency medicine resident and an attending emergency physician based on witness-reported symptom descriptions. Secondary CPSS scores will then be compared with final neuroimaging diagnoses (CT/MRI), which will serve as the diagnostic gold standard. The study will also investigate the association between physician-coded secondary CPSS scores, witness demographic characteristics, and delays in seeking emergency medical care. Research Questions 1. Are witness-derived secondary CPSS scores, as assigned by an emergency physician, a valid tool for predicting ischemic stroke? 2. Are witness-derived secondary CPSS scores of ≥1 associated with shorter recognition-to-action time (decision delay)? Research Hypotheses 1. Witness-derived secondary CPSS scores assigned by an emergency physician are a valid diagnostic tool for predicting ischemic stroke. 2. Witness-derived secondary CPSS scores of ≥1 are associated with shorter recognition-to-action time. A total of 235 stroke witnesses, including family members, friends, neighbors, or bystanders who observed the patient's initial symptoms and accompanied the patient to the emergency department with acute stroke or stroke-like symptoms, will be included. All eligible participants will provide written informed consent prior to enrollment. Witnesses will undergo a structured, physician-administered interview in which they will be asked to recall and describe the patient's first symptoms. Based solely on these reports, an emergency physician blinded to the patient's clinical examination will assign a secondary CPSS score focusing on facial droop, arm weakness, and speech impairment. Two investigators will independently score the secondary CPSS to enable interrater agreement analysis. Participants will also provide demographic data and report three key time points: symptom recognition, decision to seek care, and arrival at the emergency department. These data will be used to calculate onset-to-door time (prehospital delay), recognition-to-action time (decision delay), and call-to-door time (transfer delay). Data collection and emergency care provision will be conducted by investigators independent of those performing secondary CPSS scoring to minimize bias.
NCT07283536
Spontaneous intracranial hypotension (SIH) is a condition characterized by refractory orthostatic headache, mostly due to loss of cerebrospinal fluid (CSF). Epidural patch with autologous platelet-rich plasma (PRP), which contains numerous growth factors and cytokines, has been reported as a successful alternative for whole blood in dura repair. However, there is no report regarding the best approach to use: targeted epidural PRP patch (TEPP) versus blind epidural PRP patch (BEPP). Preliminary work has suggested that both targeted and blind approaches are effective when using whole blood for epidural patch. Furthermore, two-site blind approach could be considered as a viable initial treatment regardless of the identification of the leak for conventional targeted approach. In this study, the investigators aimed to investigate the non-inferiority of two-site BEPP compared with TEPP for the treatment of refractory SIH cases failing in conservative therapy.
NCT07295314
The goal of this clinical trial is to learn how the antifungal drug fluconazole affects the gut microbiome and immune system in healthy volunteers. The main questions it aims to answer are: * Does fluconazole change the gut bacteriome and mycobiome composition after 14 days of treatment? * How long do these changes last (4 weeks and 6 months after treatment)? * Does fluconazole affect the body's immune responses, such as blood cell activity and antifungal antibodies? Researchers will compare two groups: participants who take fluconazole for 14 days and participants who receive no intervention. Participants will: * Either take one fluconazole tablet (200 mg) daily for 14 days, or receive no treatment * Provide stool samples and blood samples at several timepoints * Return for follow-up visits up to 6 months after treatment This study is conducted at Amsterdam UMC, location AMC, with a planned enrollment of 50 healthy male volunteers aged 18-35 years.
