The goal of this clinical trial is to determine the effect of a mobile application developed for postpartum contraception counseling on contraception method choice and use among postpartum women aged 18 and older. The main hypotheses it aims to answer are; * H1: Among postpartum women, the use of highly effective contraceptive methods is higher in the group using a mobile application for contraception counseling compared to the group receiving face-to-face counseling. * H2: Among postpartum women, the use of highly effective contraceptive methods is higher in the group using a mobile application for contraception counseling compared to the group receiving routine postpartum care. * H3: Contraceptive method continuation and satisfaction are higher in the group using a mobile application for postpartum contraception counseling compared to the group receiving face-to-face counseling. * H4: Contraceptive method continuation and satisfaction are higher in the group using a mobile application for postpartum contraception counseling compared to the group receiving routine postpartum care. Researchers will compare three groups: 1. Group receiving contraception counseling via mobile app: Women in this group will have a postpartum contraception counseling mobile application installed on their phones and will use the application for 12 weeks. 2. Group receiving face-to-face contraception counseling: These women will receive face-to-face contraception counseling during the initial encounter, and an educational booklet will be provided at the end of the counseling session. 3. Control group: Women in this group will receive routine postpartum care. All groups will be followed up at three time points: the initial encounter, the first follow-up, and the second follow-up. The initial encounter will be conducted face-to-face at the hospital within the first 5 days postpartum. The first follow-up will take place by phone at 6 weeks postpartum, and the second follow-up will be conducted by phone at 12 weeks postpartum.
NCT07251868
The goal of this real-world study (RWS) is to evaluate the effectiveness of Trop-2 ADC (sacituzumab govitecan) in treating breast cancer patients with brain metastases, and to understand the safety profile of this drug in real clinical practice across multiple centers. The main questions it aims to answer are: Does Trop-2 ADC (sacituzumab govitecan) improve intracranial outcomes in breast cancer patients with brain metastases (e.g., intracranial objective response rate, intracranial progression-free survival)? What types and rates of adverse events do breast cancer patients with brain metastases experience when receiving Trop-2 ADC (sacituzumab govitecan)? This is a multicenter real-world study, which will collect and analyze data from breast cancer patients with brain metastases who have received Trop-2 ADC (sacituzumab govitecan) in routine clinical care (no randomization or placebo control, consistent with real-world clinical scenarios). Participants (breast cancer patients with brain metastases who received Trop-2 ADC) will have their data collected from: Electronic health records (EHRs) across multiple medical centers Regular clinical follow-up visits (e.g., once every 4-8 weeks) for imaging assessments (to evaluate brain metastasis changes) and safety monitoring Medical records documenting treatment responses, disease progression, and any adverse events during treatment and follow-up
NCT07252557
This single-center randomized controlled trial evaluates the effects of cold (15-20°C) versus room-temperature (30-35°C) water gargling on oral mucositis severity, pain, and comfort in patients with head and neck cancer undergoing radiotherapy. Participants will rinse their mouth four times daily for 30-60 seconds over a 6-week radiotherapy course, with follow-up for two additional weeks. The study hypothesizes that cold-water rinsing can reduce the severity of radiation-induced oral mucositis (RTOM) and pain, improve oral comfort, and minimize treatment interruptions.
NCT07252570
Introduction: Pre-hepatic portal hypertension of malignant origin can lead to severe complications such as refractory ascites or gastrointestinal bleeding, significantly impairing patients' quality of life. Available therapeutic options are mainly symptomatic and do not address the venous obstruction. Portal vein stenting represents a minimally invasive alternative, which remains poorly studied in this setting. The aim of our study was to evaluate portal stent patency, as well as clinical efficacy and safety, in patients with symptomatic malignant stenosis or occlusion of the portal system. Methods: The team conducted a retrospective cohort study including 63 consecutive patients treated between April 2004 and March 2024 at CHU l'Archet and CAL Nice for symptomatic malignant stenosis or occlusion of the portal system. All patients underwent percutaneous transhepatic portal vein stenting with uncovered self-expandable metallic stents. The primary endpoint was stent patency, defined as the interval between implantation and the occurrence of an occlusion confirmed by imaging or end of follow-up. Secondary endpoints included technical success, clinical success (improvement of portal hypertension signs), and the occurrence of adverse events, graded according to the 2017 SIR classification.
NCT06805175
The main aim of this study is to understand if an experimental vestibular implant system can improve balance performance. The system consists of a vestibular implant combined with a cochlear implant sound processor and programming software. The implant is designed to preserve hearing in the implanted ear. The vestibular implant is surgically placed under the skin just behind the ear in the mastoid bone and has an electrode that stimulates the vestibular nerve. A sound processor is worn behind the ear and powers the implant via the coil. The study will be conducted in adults with bilateral vestibulopathy (BVP) who have normal to severe hearing loss in the inner ear. The study participants will undergo a series of tests that include evaluations of their balance and hearing and self-reported questionnaires on their balance and general health.
NCT07249580
This cross-sectional comparative study aims to assess and compare the self-efficacy and perceived stress levels among physiotherapy interns in Turkey and Egypt. The transition from academic study to clinical practice is a critical and often challenging stage for physiotherapy students, requiring the integration of theoretical knowledge and practical skills in real-world clinical environments. Self-efficacy, derived from Bandura's Social Cognitive Theory, refers to an individual's confidence in their ability to perform specific tasks and achieve desired outcomes. In physiotherapy education, self-efficacy influences clinical reasoning, patient assessment, treatment planning, communication, and interprofessional collaboration. Meanwhile, perceived stress reflects how individuals appraise situations as stressful or demanding, which can affect their confidence and clinical performance. The study will include 200 physiotherapy interns-100 from Turkey and 100 from Egypt-who are currently completing supervised clinical internships at accredited universities. Data will be collected using an online survey containing three parts: a demographic and educational background form, the Physiotherapy Intern Self-Efficacy Scale - Likert Version (PISE-L), and the Perceived Stress Scale (PSS). The primary objective is to compare self-efficacy levels between interns from the two countries and explore how differences in educational structures and clinical training environments relate to professional confidence and stress levels. The study also aims to identify correlations between perceived stress and self-efficacy among interns. Findings from this research are expected to provide valuable insights for improving physiotherapy education programs by highlighting factors that influence students' readiness for professional practice.
NCT07249996
The goal of this observational study is to learn about the causes, severity, and long-term effects of respiratory tract infections (RTIs) in young children from birth to five years of age in Colombia and Panamá. The main questions it aims to answer are: How often do respiratory infections occur in children under two years old, and which viruses or bacteria cause them? Why do some children develop more severe infections than others? Do early infections or vaccinations change how the immune system responds to future illnesses? How do viruses and bacteria interact in the respiratory tract to influence disease severity and long-term respiratory health? Researchers will follow newborns from birth until age five to understand how respiratory infections develop and affect children's health over time. Participants will not receive any experimental treatment. Families who join the study will: Be contacted twice a week through a phone app or phone calls to check for symptoms of respiratory infection. Attend in-person visits if their child becomes ill and every six months for routine follow-up. Provide nasal and blood samples during illness episodes so researchers can identify the viruses or bacteria causing infection and study how the immune system responds. This study began in May 2024 and is being conducted in Cali, Colombia, and Panamá City, Panamá. The research team plans to continue to include participants and continue active follow-up until the children reach five years of age. The information collected will help scientists and health professionals understand how different pathogens cause respiratory infections, what factors increase the risk of severe illness, and how early infections may influence long-term lung health. The study's findings will support future efforts to prevent and treat respiratory diseases in young children.
NCT07249957
This is a domestic single-center prospective clinical trial. The study selected patients with histologically confirmed cervical squamous cell carcinoma, diagnosed as stage IIb according to the FIGO 2018 staging principle (tumor size \< 4 cm). The patients first received 6 cycles of induction chemotherapy (carboplatin (AUC2) + paclitaxel (80 mg/m2), q1w), followed by concurrent chemoradiotherapy with a platinum-based regimen. The external beam radiation field only covered the entire uterus (including the primary lesion of the cervix), the bilateral parametrium, and the lesion of the cervix/vagina extending 3 cm downward. A total of 60 participants are planned to be included in the study.
NCT07249437
Oral cancer is a common cancer worldwide, with approximately 250,000 new cases annually and a high mortality rate. Its major risk factors include smoking, alcohol consumption, and betel nut chewing. Current screening methods rely heavily on visual inspection by specialist physicians and invasive biopsy of lesions, but they suffer from limitations such as insufficient sensitivity, sampling errors in biopsies, and low patient compliance. This study proposes an innovative cross-sectional randomized trial aimed at evaluating two non-invasive techniques-oral digital imaging photography (high-resolution microendoscopy, HRME) and liquid-based cytology (LBC) of the oral mucosa-in order to optimize the screening of oral precancerous lesions.
NCT07249333
Neoadjuvant radiotherapy plays an important role in the treatment of locally advanced colorectal cancer. Although radiation therapy is extremely important in reducing the tumor mass, downstaging, and therefore providing conditions for curative surgery, neoadjuvant therapy can increase the risk of perioperative complications, which can lead to slower patient recovery, greater perioperative morbidity, prolonged hospitalization, and increased treatment costs. The aim of the study is to determine whether there is a difference in the incidence of perioperative complications after radical colorectal cancer surgery between patients who received neoadjuvant radiotherapy and those patients who did not undergo neoadjuvant radiation. Data is collected from the medical documentation and information system of the Oncology Institute of Vojvodina. Demographic characteristics of patients, comorbidities, length of hospital stay, length of treatment in the intensive care unit, occurrence of complications in the perioperative period, as well as data on neoadjuvant therapy are analyzed. All included patients are of similar general condition, as determined by the CFS (Clinical Frailty Scale). Intraoperative complications are graded using the ClassIntra classification of intraoperative adverse events, and the presence of postoperative adverse events are assessed and classified using the Clavien-Dindo classification of postoperative complications and the HARM (HospitAl stay, Readmission, Mortality rate) score.
NCT07249216
Neovascular age-related macular degeneration (nAMD), also called wet AMD, can cause serious vision loss. While anti-VEGF (anti Vascular Endothelial Growth Factor) treatments such as ranibizumab help many patients, about 20 40% have a suboptimal response. In this study, the investigators want to identify other factors (beyond VEGF) that might be driving the disease in these non-responding patients. By looking at samples from inside the eye (vitreous humor) and comparing "good responders" to "suboptimal responders", the investigators hope to find potential new treatment approaches or biomarkers for nAMD.
NCT07249164
This observational study uses de-identified electronic health record data from the TriNetX Global Collaborative Network (2010-01-01 to 2025-07-01) to examine whether perioperative dexmedetomidine (DEX) is associated with 30-day outcomes after adult cardiac surgery. Adults aged 18-100 years undergoing first-time coronary artery bypass grafting or heart valve surgery are included. Exposure is any DEX administration from 24 hours before to 48 hours after the index operation; comparators receive no DEX in this window. The primary outcome is delirium within 30 days. Secondary outcomes are 30-day all-cause mortality, acute kidney injury, pneumonia, sepsis, red blood cell transfusion/major bleeding, myocardial infarction, ischemic stroke/transient ischemic attack, atrial fibrillation, mechanical ventilation \>96 hours (days 4-30), and 30-day readmission (days 1-30). No treatments are assigned by investigators and no identifiable information is used. Findings aim to inform perioperative sedation strategies in routine cardiac surgery care.
NCT07248020
This clinical study investigates the anti-inflammatory and anti-cancer properties of a high-bioavailability formulation of curcumin (BCM-95) in patients with mid-to-low rectal cancer receiving neoadjuvant chemoradiotherapy (nCRT). Curcumin, a polyphenolic compound derived from Curcuma longa, has demonstrated potent anti-inflammatory and anti-neoplastic activities through the modulation of multiple molecular signaling pathways. It has been recognized by the U.S. Food and Drug Administration (FDA) as "Generally Recognized as Safe" (GRAS; GRN No. 686), with an excellent safety profile when administered orally. Reported adverse effects are rare and primarily related to interference with bile secretion or iron metabolism. Despite its biological potential, conventional curcumin exhibits extremely low oral bioavailability due to its lipophilic nature, rapid metabolism, and systemic elimination. Clinical studies have reported that even at an oral dose of 12 grams per day, the maximum plasma concentration reaches only about 0.051 mg/mL, with up to 75% of the administered dose excreted in feces. To overcome this limitation, the current trial utilizes a curcumin formulation with enhanced absorption (BCM-95), which combines curcumin with essential oils of turmeric to improve systemic bioavailability. The primary objective of this single-arm, phase II trial is to evaluate whether oral curcumin supplementation can mitigate radiation-induced gastrointestinal toxicity-particularly radiation enteritis-during neoadjuvant chemoradiotherapy for rectal cancer. The secondary objectives include assessing its effect on treatment response, such as the pathological complete response (pCR) rate, tumor regression grade, and patient-reported outcomes related to bowel function and quality of life. In addition, a translational research component is embedded within this study. Serial tumor tissue and blood samples will be collected at predefined time points to explore the molecular and immunological mechanisms underlying curcumin's therapeutic effects. Analyses will include assessments of inflammatory cytokines, oxidative stress markers, and tumor microenvironmental changes using molecular and histopathologic methods. Overall, this study aims to provide both clinical and mechanistic evidence supporting the potential of high-bioavailability curcumin as a safe, adjunctive therapeutic strategy to improve treatment tolerance and oncologic outcomes in rectal cancer patients undergoing chemoradiotherapy.

This work will examine if a technique called Transcutaneous Spinal cord stimulation (tSCS), when used with concurrent specific arm and hand exercises, helps improve arm and hand movements in CYP with HCP. Does Transcutaneous Spinal Cord Stimulation (tSCS), when combined with specific arm and hand exercises, improve upper limb function in children and young people (CYP) with Hemiplegic Cerebral Palsy (HCP)? -To determine the feasibility and effectiveness of Transcutaneous Spinal Cord Stimulation (tSCS) combined with targeted arm and hand exercises in improving the upper limb function in children and young people with Hemiplegic Cerebral Palsy (HCP).
NCT07247422
Atrial fibrillation (AF) is the most common arrhythmia, with a lifetime risk of 1 in 3-5. In cases of rapid ventricular rate, patients often experience low blood pressure, making standard rate and rhythm control medications contraindicated. While cardioversion may be necessary, it is often ineffective in long-standing AF and can lead to left ventricular stunning. This creates a vicious cycle, worsening heart failure and cardiogenic shock. AV node ablation may be required, but it is irreversible and carries risks, including complications from long-term pacing. Therefore, temporary pacing may be a preferable option to allow for hemodynamic improvement and better ventricular filling. Research suggests that parasympathetic fibers innervating the AV node can modulate conduction. Ablation in these fibers has shown promise for treating vagal-mediated syncope, and high-frequency pacing may provide chronic heart rate suppression. Intermittent pacing has also been effective in reducing ventricular rates in atrial fibrillation to prevent inappropriate ICD shock. This may be potentially beneficial for patients with uncontrolled fast AF. In a proof-of-concept study with five patients, pacing at 30Hz and 10mA in the coronary sinus resulted in a dose-dependent prolongation of the ventricular cycle length during AF, with stable blood pressure and no discomfort reported. This suggests that pacing these fibers could achieve rate control without the need for medications or AV node ablation, with no complications observed. This study aims to evaluate safety and efficacy of temporary cardio-neural pacing (CNP). This is a prospective cohort study involving patients with atrial fibrillation (AF) and rapid ventricular conduction who have failed or are contraindicated for rate control with antiarrhythmic medications. Enrolled patients will be followed up for 1 month.
NCT03153020
The effectiveness of emergency management of acute ischemic stroke has improved considerably in recent years with thrombolysis and more recently thrombectomy. This improvement is accompanied by an increase in the number of stroke survivors. One of the major issues for these ever-increasing survivors is the prevention of recurrence. According to data from the 3 French registries, more than 20% of patients have at least one recurrence. Secondary prevention treatment has demonstrated his efficacy to prevent stroke recurrence. This evolution justifies identifying factors associated with adherence to secondary prevention treatment, measured at 1 year post-stroke / transient ischemic attack (TIA), in patients included in the STROKE 69 cohort.

NCT04251780
Recent human studies found tissue sodium storage in patients with hyperaldosteronism that could be detected non-invasively by 23Na-MRI. Tissue sodium accumulation could be mobilized upon treatment of hyperaldosteronism. Besides, former animal studies applying chemical electrolyte analysis indicate that this aldosterone induced sodium storage might be accompanied by intracellular potassium loss. Wether such an intracellular tissue potassium loss occurs in vivo in patients with hyperaldosteronism and if this deficiency can be corrected by treatment is unclear. The investigators will employ 39K-MR Imaging at 7Tesla to further assess this hypothesis.
NCT04342013
The purpose of this study is to assess the effect of a novel clinical decision support application on the rate of perioperative medication errors and preventable adverse medication events. The investigators hypothesize that the perioperative clinical decision support application will reduce the incidence of perioperative medication errors and adverse medication events compared to the standard of care.
