NCT07300631
Recently, concerns have been raised by regulators that there is little data about the long-term safety of rectal hydrogel spacers for use in conjunction with radiotherapy treatment for prostate cancer. To address this, this study will collect data about the short-term side-effects and long-term safety of SpaceOAR and SpaceOAR Vue rectal hydrogel spacers in men who receive them in the UK and France. Men who have agreed to receive these spacers as part of their standard medical care will be asked to take part in the study whereby data about their treatment and health will be collected from their medical records and from members of the clinical team who deliver their treatment. Additionally, men will be asked to consent to completing questionnaires about their experiences of side effects from their treatment. Further information will be collected about their clinical characteristics before they receive a spacer, the physician-rated clinical performance of the spacer insertion procedure, their radiotherapy treatment plan and details of the other treatments they are also receiving which could influence the types and extent of side effects they experience. Data collection will span eight time points: pre-spacer insertion, spacer insertion, the start of radiotherapy, post-radiotherapy follow-up, 6-month follow-up, 12-month follow-up, 24-month follow-up \& 36-month follow-ups. Outside of these timepoints treatment-related adverse event data will be concurrently reported and collated. Participants' treatments will not be changed as a result of their participation in this study. Data from this study will be used to summarise the characteristics of this study population, physicians' perceptions of the spacer implantation procedure, the radiotherapy treatments plans made, and the types, extent and timing of treatment-related adverse events and side effects.
NCT06612528
Transcranial direct current stimulation (tDCS) can be used to temporarily and reversibly modulate brain functions and is an increasingly utilized tool to investigate the relationships between brain and behavior. This study aimed to identify the effects of tDCS on vocal quality, vocal range, neuromotor functioning of the larynx and self-reported vocal effort in vocally healthy singers. This is a triple-blinded, sham-controlled, randomized clinical trial. The participants were randomized to one of the three tDCS groups (primary motor cortex, cerebellum or sham). In each group a voice training was applied at the same tDCS time. The three groups are: (i) cerebellum; (ii) primary motor cortex (M1); (iii) sham. The tDCS parameters in the active groups are anodal - 2mA for 20 minutes, at the sham group the stimuli are finished 30 secondes before starting. Volunteers passed for 10 intervention days and they were evaluated for vocal performance before the sessions, in the day 5 of intervention, the last day of intervention (day 10) and 1 month later for follow up evaluation. Voice recordings was taken to assess the following vocal parameters: vocal range profile (VRP) at weak and strong intensities; vocal quality (jitter, shimmer, irregularity, glottal-to-noise excitation ratio, CPPS,HNR, and dysphonia acoustic index) at weak, habitual, and strong intensities; laryngeal diadochokinesis, and self-reported vocal effort using the adapted Borg CR10 scale.

Researchers will compare patients with acute ischemic stroke to patients with transient ischemic attacks to study the effect of acute ischemic brain lesions. Participants will * undergo cardiovascular autonomic function testing; * receive structural and functional MR imaging; * provide blood samples for determinaton of serological biomarkers auf dysautonomia.
NCT07565714
The aim of the study is to examine the effect of imagery rescripting (ImRs) in the context of utilizing large language models (LLMs). Intervention will involve the prior presentation of the most aversive fragment of the memory, the so-called 'hotspot.' This intervention will allow for the replication of the effect described by Dibbets and Arntz (2016), according to which the prior activation of the most emotional element of a memory enhances the effectiveness of ImRs. The study is also significant due to another ongoing study in which a substantial number of participants have already been examined; however, due to the exhaustion of funds, it was not possible to utilize the remainder of the recruited sample. Investigating an additional condition will allow for a more complete utilization of the available participant pool and significantly increase the project's scientific value by comparing the traditional ImRs mechanism with its AI-generated version.

NCT07569835
VARIABLES TO BE COLLECTED AND SOURCE The primary efficacy endpoint will be the maintenance of flatfoot correction over time, assessed both clinically (tip-toe test, Jack test, tip-toe walking test) and radiologically (evaluation of Meary's angle on the lateral foot view and the talocalcaneal angle). The secondary efficacy endpoint will be the absence of pain at follow-up, assessed using the VAS scale, and evaluation of the footprint using a podoscope. TIP-TOE TEST: The patient is observed under weight-bearing conditions and then while rising onto the toes. If the foot is flexible, the plantar arch-previously absent-reappears when standing on tip-toe. JACK TEST: This consists of passive dorsiflexion of the hallux under weight-bearing conditions. If the previously absent arch reappears, the flatfoot is considered flexible. TIP-TOE WALKING TEST: The patient walks for about ten steps on tip-toe. The examiner observes any varus alignment of the hindfoot and reconstruction of the plantar arch. MEARY'S ANGLE: Measured between the longitudinal axis of the talus and that of the first metatarsal on a weight-bearing lateral foot radiograph. TALOCALCANEAL ANGLE: Measured between the longitudinal axis of the talus and that of the calcaneus on a weight-bearing dorsoplantar foot radiograph. VAS: The Visual Analog Scale for pain is a tool used to measure the subjective characteristics of pain experienced by the patient, ranging from 0 (no pain) to 10 (worst imaginable pain). PODOSCOPE FOOTPRINT ASSESSMENT: Evaluation of the isthmus (the narrow portion of the footprint connecting the heel to the forefoot). The foot is considered normal when the width of the isthmus is between one-third and one-half of the maximum width of the forefoot. SAMPLE SIZE AND STATISTICS In Prof. Giannini's study, 30 patients were enrolled; approximately 30% were lost to follow-up over 12 years. Barring further losses, about 20 patients currently followed at Clinic I are expected to be available. ENROLLMENT PROCEDURE Eligible patients will be enrolled in the study only after providing written informed consent. No data collection, procedures, or analyses will be performed prior to obtaining consent. DATA COLLECTION Clinical data required for the study will be extracted from patients' medical records and source documents. A dedicated data collection form will be used to record clinical information and the results of the analyses by the study. For each enrolled patient, a Case Report Form (CRF) will be completed.
NCT04945993
The aim of root canal treatment, or endodontic treatment, is to treat pulpal or periapical diseases and thus transform a pathological tooth into a healthy, asymptomatic and functional entity on the dental arch. The diagnosis of pulp pathology is based on the symptomatology described by the patient, on data from the clinical examination and tests performed as well as the radiographic examinations. Different families of root canal sealers are used in endodontics: cements based on zinc oxide-eugenol (ZOE), resin-based materials, and calcium silicate-based cements. They provide a stable and hermetic sealing. The Septodont laboratory has developed and manufactured endomethasone N, a zinc oxide-eugenol root canal sealer. The aim of this retro-prospective PMCF study is to collect long term clinical and safety data on root canal obturation after treatment or retreatment by Endomethasone N.

NCT07570251
Breast cancer is one of the most common cancer types worldwide and accounts for approximately 31% of all cancers in women. The global incidence of breast cancer is increasing, making it a significant public health problem. Advances in breast cancer management, including surgery, chemotherapy, radiotherapy, and hormone therapy, have contributed to reduced mortality rates. However, despite these positive developments, chemotherapy-related cognitive impairment, commonly referred to as "chemobrain," may occur. Chemotherapy-induced cognitive impairment may manifest as deficits in memory, learning, attention, motor functions, executive functions, visual-spatial abilities, and information processing speed. These impairments negatively affect patients' quality of life and daily functioning. In this study, cognitive education activities were designed and implemented to address these impairments. These activities aimed to support attention, memory, and executive functions and to minimize cognitive deficits. The purpose of this study was to examine the effects of cognitive activities applied to breast cancer patients receiving chemotherapy on cognitive functions, depression levels, and odor recognition abilities. The study sought to answer the following research questions: 1. What is the effect of cognitive education activities on odor recognition ability in breast cancer patients receiving chemotherapy? 2. What is the effect of cognitive education activities on cognitive functions in breast cancer patients receiving chemotherapy? 3. What is the effect of cognitive education activities on depression levels in these patients?
