Filter by:Based on the high expression of specific receptors on the surface of diseased tissues and neovascularization, noninvasive targeted molecular imaging can be used to visualize lesions in vitro by combining specific ligands labeled with short half-life isotopes. In this study, a novel dual-target imaging agent 68Ga-RM26-RGD was used for clinical study of tumor PET/CT imaging to further verify its clinical application value.
The basic mechanisms underlying comprehension of spoken language are still largely unknown. Over the past decade, the study team has gained new insights to how the human brain extracts the most fundamental linguistic elements (consonants and vowels) from a complex and highly variable acoustic signal. However, the next set of questions await pertaining to the sequencing of those auditory elements and how they are integrated with other features, such as, the amplitude envelope of speech. Further investigation of the cortical representation of speech sounds can likely shed light on these fundamental questions. Previous research has implicated the superior temporal cortex in the processing of speech sounds, but little is known about how these sounds are linked together into the perceptual experience of words and continuous speech. The overall goal is to determine how the brain extracts linguistic elements from a complex acoustic speech signal towards better understanding and remediating human language disorders.
Background and study aims: Computerised Tomography (CT) head scans are frequently requested by Emergency Department (ED) clinicians as one of the investigations for their patients. This often causes a delay when waiting for specialist radiologists to report the findings of the scan. The purpose of this study is to see if online training can improve the ability of ED clinicians to interpret the scans themselves, to a level sufficient to make clinical decisions based on their findings and to explore what aspects of this process they find most challenging. Participants: Emergency Department clinicians who are working in the Emergency Departments of participating sites between April to September 2022 (inclusive), who request CT Head scans as part of their routine clinical practice. What does the study involve?: 180 ED clinicians will be recruited across 6 hospital sites in the United Kingdom. All will undertake a baseline online assessment to measure their accuracy in interpreting CT head scans. One group will then undertake an online training module, with a subsequent assessment immediately afterwards, then over the following 3 months will record interpretations for 30 CT head scans. Head images encountered in participants' routine clinical practice, and their findings, will be compared with the radiology reports for each scan. Participants will then undertake further online assessments 3 and 6 months after the start of the study. Their overall results will be compared with a control group, who will undergo the same process, but undertake the online training after they have tried to interpret 30 scans in their clinical practice. Participants will continue to base their clinical decisions on radiologist reports, not their own interpretations, so patient care will not be affected by this study.
To our knowledge, the investigators have not found any scientific article dealing with cooperation between radiation oncologists and medical radiation technologists in the context of monitoring patients undergoing radiotherapy. Cooperation protocols between health professionals are in progress but concern mainly technical procedures (ultrasound, laserthermal sessions). This study aims to evaluate whether MERMs, after training by physicians, can monitor clinical signs (for usual well-described toxicities) during treatment via a dedicated consultation. This approach participates in the development of new professions and cooperation protocols between health professionals. This mission of accompaniment on a dedicated time would make it possible to develop the caring role of the medical electroradiology manipulator.
Patients with brain injury secondary to stroke, surgery, or trauma frequently suffer from homonymous hemianopia, defined as vision loss in one hemifield secondary to retro- chiasmal lesion. Classic and effective saccadic compensatory training therapies are current aim to reorganize the control of visual information processing and eye movements or, in other words, to induce or improve oculomotor adaptation to visual field loss. Patients learn to intentionally shift their eyes and, thus, their visual field border, into the area corresponding to their blind visual field. This shift brings the visual information from the blind hemifield into the seeing hemifield for further processing. Patients learn, therefore, to efficiently use their eyes "to keep the 'blind side' in sight". Biofeedback training (BT) is the latest and newest technique for oculomotor control training in cases with low vision when using available modules in the new microperimetry instruments. Studies in the literature highlighted positive benefits from using BT in a variety of central vision loss, nystagmus cases, and others.The purpose of this study is to assess systematically the impact of BT in a series of cases with hemianopia and formulate guidelines for further use of this intervention in vision rehabilitation of hemianopia cases in general.
The purpose of this study is to obtain images of brain tumours during surgery using a new type of surgical camera. The study will assess how the information obtained from the images during surgery matches the removed tissue. Data will also be used to develop the system's key computer-processing features. This will enable real-time information to be given to the surgeon whilst they are performing the procedure and has the potential to make neurosurgery safer and more precise.

Over the last decades, research has shown that poor nutritional status can adversely impact prognosis and increase toxicities during treatment for childhood cancer. EPICkids is a collaboration between the International Initiative for Pediatrics and Nutrition, the International Agency for Research on Cancer, and sites throughout three Southern European countries (Spain, Greece, and Italy). The primary aim of EPICkids is to establish an informational resource on critical nutrition parameters wherein we can describe the trajectory of nutritional status among Southern European children and adolescents with acute lymphoblastic leukemia (ALL) and favorable biology brain tumors, investigate lifestyle behaviors, sociodemographic factors, and quality of life and correlate these indicators with clinical outcomes. The specimens obtained with the proposed study will foster future studies on nutrition and prevalent childhood cancer as well as establish a framework to develop evidence-based guidelines for European children with cancer, utilizing regional, European data. We plan to recruit 900 patients with ALL and 1400 patients with a favorable biology brain tumor over five years. Nutrition parameters and lifestyle factors will be measured at systematic timepoints over the study period. Stool and blood specimens will be collected at each timepoint. Eligible patients will be between 3 and 21 years of age.
The objectives of the study are (1) to evaluate the feasibility of using a combined spin- and gradient- echo (SAGE) sequence in dynamic susceptibility contrast magnetic resonance imaging (DSC MRI) and (2) to determine quantitative estimates of vessel density and size to differentiate between areas of radiation necrosis and tumor recurrence.
The aim of this study is to describe a patient's Spiritual Needs and related factors that contribute to a patient's Spiritual Well-Being in the context of perioperative care. The primary objective of this study is to examine the fit of the Structural Equation Model (SEM) of the theory on Spiritual Well-Being (SWB) and explain how SWB is affected by Symptom Burden (SB), Psychological Distress (PsD), and Spiritual Needs (SN) reported by the patients with brain tumors before having surgery.
