NCT06539559
This study is a prospective, multicenter, phase II randomized clinical trial. It is planned to enroll 60 patients with advanced HER2 negative breast cancer, who will be randomly assigned to the experimental group and the control group in a 1:1 ratio. The participants will receive either eribulin combined with bevacizumab or eribulin monotherapy. Every treatment cycle will last for 21 days, with weekly monitoring of blood routine, blood biochemistry and other indicators. Imaging examinations will be conducted every two cycles and the efficacy will be evaluated according to RECIST 1.1 standard. The life quality questionnaire is arranged at baseline and every 3 months after enrollment, and the long-time survival will be followed every 3 months after treatment. The primary endpoint is progression-free survival (PFS), the secondary endpoints are objective response rate (ORR), clinical benefit rate (CBR) and overall survival (OS). The investigators will also focus on the treatment-related adverse events (TRAE) and quality of life (QoL) assessment. At the same time, this study also aims to explore the resistant mechanisms of anti-angiogenic drugs. The investigators plan to collect peripheral venous blood samples at 3 time points: baseline, during treatment, and end of treatment. All the dynamic samples will be used for transcriptome sequencing to obtain the gene sets. And based on the optimal therapeutic efficacy, all the participants will be divided into response group and non-response group. GO and KEGG enrichment analysis will be subsequently performed between different therapeutic efficacy groups to draw gene interaction networks, identify key action nodes and explain the mechanism of anti-angiogenic drug resistance.
NCT05931068
Rationale: Complication rates after major liver resections remain as high as 43%. Many initiatives have been taken to reduce postoperative morbidity. As such, prehabilitation programmes are increasingly used for patients undergoing major abdominal surgery. Improvement of aerobic fitness has been proven to reduce complication rates, especially in high-risk patients (those with a low preoperative aerobic capacity). Different conceptual hypotheses exist of the underlying mechanism of variability in postoperative complications and prehabilitation response. One of the complementary rationales focusses on homeostasis-allostasis before and after surgery, more specifically on the preoperative aerobic capacity to meet postoperative metabolic demands. However, more insight in postoperative metabolic demands (energy expenditure) during in-hospital recovery from major abdominal surgery in relation to preoperative resting metabolic demands and maximal aerobic capacity is essential to understand the increase in metabolic demands coinciding with major surgery in relation to the body's reserve capacity. This information can be used to better understand the rationale behind exercise prehabilitation, as well as to optimize the content of preoperative treatment for unfit patients, for instance by means of personalized prehabilitation programs that might improve postoperative outcomes. Objective: This study aims to explore the difference of pre- and postoperative energy expenditure in patients undergoing major elective liver resection and relate this to their preoperative aerobic capacity. Study design: The study will be a prospective observational study with thorough pre- and postoperative measurements of energy expenditure. Energy expenditure will be measured using the doubly labelled water method, as well as by indirect calorimetry. To assess aerobic capacity, cardiopulmonary exercise testing will be performed pre- and postoperatively. Additionally, accelerometers will be used to evaluate pre- and postoperative physical activity levels. Study population: Patients aged ≥18 years undergoing major liver resection (≥3 segments) will be asked to participate. The inability to perform cardiopulmonary exercise testing, neo-adjuvant chemotherapy, and cirrhotic liver are reasons for exclusion. Main study parameters/endpoints: The main study parameter is the difference of energy expenditure pre- and postoperatively, as measured with doubly labelled water and indirect calorimetry. Secondary endpoints: Additionally, as secondary endpoints, aerobic fitness, physical activity level, and postoperative complications will be assessed.
NCT06080646
Deficits in motivation and pleasure are common in depression, and thought to be caused by alterations in the ways in which the brain anticipates, evaluates, and adaptively uses reward-related information. However, reward processing is a complex, multi-circuit phenomenon, and the precise neural mechanisms that contribute to the absence or reduction of pleasure and motivation are not well understood. Variation in the clinical presentation of depression has long been a rule rather than an exception, including individual variation in symptoms, severity, and treatment response. This heterogeneity complicates understanding of depression and thwarts progress toward disease classification and treatment planning. Discovery of depression-specific biomarkers that account for neurobiological variation that presumably underlies distinct clinical manifestations is critical to this larger effort.

Although the cause of Multiple Sclerosis (MS), one of the common demyelinating diseases of the central nervous system, has not yet been fully elucidated, autonomic nervous system dysfunction has been suggested in its etiology. Symptoms such as fatigue, problems with bladder, bowel, cardiovascular, sleep, sexual and sweating functions, abnormal sympathetic skin response or decreased heart rate variation support this hypothesis. In the treatment of many neurological diseases such as Multiple Sclerosis, complementary medicine practices and non-traditional therapies have recently been shown to be effective in addition to conventional practices. One of these practices, craniosacral therapy (CST), uses manual palpation and manipulation of the craniosacral system to influence sensory, motor, cognitive and emotional processes in the nervous system. In addition, it is thought that applying external force to certain bone elements can have a positive effect on various symptoms in patients with MS, based on the knowledge that it can be transmitted within the system.

NCT06522776
The frequency of psychological conditions in recovered COVID-19 patients with Acute Kidney Injury (AKI) and their informal primary caregivers (IPC) is unknown; as well as the effects of psychological therapy in this population. The present study was initiated to determine the effectiveness of a brief remote psychological intervention (BRPI) to reduce anxious and depressive symptoms in survivors of AKI. The investigator designed a single-case experimental design A-B with prospective follow-up. We used the Patient Health Questionnaire-9 (PHQ-9) and the General Anxiety Disorder Scale-7 (GAD-7) to screen for depressive and anxiety symptoms, one week later after hospital discharge. Those with moderate or severe symptoms received cognitive behavioral therapy (CBT) and were evaluated over time with the instruments and daily self-report of symptoms. The statistical analysis was conducted using statistical software.

NCT06509724
Radical hysterectomy and radiation therapy are standard treatments for cervical cancer. However, there are no reported studies on the frequency of side effects and treatment outcomes when hypofractionated radiation therapy and intensity modulated radiation therapy(IMRT) are used during radiation therapy. Hypofractionated radiation therapy increases the daily dose and reduces the number of treatment sessions, which may increase the risk of side effects, but its safety has been confirmed in some cases of early cervical cancer and endometrial cancer. Additionally, applying IMRT, a technique designed to protect normal tissue, during concurrent chemoradiotherapy has shown positive results in reducing the incidence of acute side effects. Investigators previously demonstrated that combining hypofractionated IMRT with chemotherapy for high-risk postoperative cervical cancer patients resulted in high survival rates and low toxicity in a phase 2 exploratory study. Base on this result, this study aimed to compare the efficacy and safety of conventional fractionated radiation therapy and hypofractionated radiation therapy.
NCT05270239
Multiple sclerosis (MS) is an autoimmune disease that causes cognitive and motor disabilities and contributes to decrease patients life quality. Previous results described that there are some MS patients that showed (at least in some phases of the disease) neuroplasticity processes that are able to compensate some cognitive deficits. Moreover, neuroplasticity processes seem to be limited and related to the degree of gray matter atrophy (patients with less atrophy show grater neuroplasticity than those with higher atrophy level). The aims of this project are: 1. to study behavioral changes (post-training) induced by two different rehabilitation programs: a)cognitive training focused on exclusively enhancing working memory and b) aerobic + cognitive training aimed to enhance attention, working memory processes and motor capabilities using a virtual reality game. 2. to study neuroplasticity changes (post-training functional connectivity changes) induced by these rehabilitation programs 3. to observe the role of the atrophy in brain neuroplasticity processes. Neuropathological status and neuroplasticity processes (studied using neuroimaging tools) as well as cognitive performance using neuropsychological tools will be assessed in a group of MS patients (with different phenotypes) at two different time points: before any training (S1) and after 10 days of training (S2). This project will be financed by the Ministerio de ciencia, innovación y universidades of the Spanish government and also have been approved by the Ethical committee of Universitat Jaume I.
