Schizophrenia (SZ) is a broad clinical entity characterized by different subjective symptoms,behavioural signs, and disease course. Research has pointed to numerous biological indicators tentatively associated with neurocognitive dysfunction, brain structural and neurochemical alterations. Cognitive deficits occur as early as the prodromal phase of the illness and significantly determine its outcome. Pathophysiologically, SZ is regarded as a disconnectome disorder in which frontal and temporal brain regions are functionally disconnected, which contributes substantially to the development of cognitive dysfunction. Impaired connectivity is related to synaptic (microconnectivity) and myelin (macroconnectivity) plasticity. With design-based stereology, a decreased number of oligodendrocytes (OLs) in the CA4 hippocampal subregion as the basis for disturbed myelination and impaired cognition, but also a decrease in the prefrontal cortex were observed. Animal studies demonstrated that clemastine enhances remyelination by increasing the differentiation of oligodendrocyte precursor cells (OPCs) and showed that aerobic exercise increases the rate of remyelination and proliferation of OPCs; this clinically meaningful effect of aerobic exercise is stronger in combination with clemastine. Furthermore, aerobic exercise improves everyday functioning, measured by the Global Assessment of Functioning (GAF) scale, and cognitive dysfunction in SZ and increases hippocampal volume, especially the volume in the hippocampal CA4 subregion. This regional volume change correlates negatively with global and cell-specific polygenic risk scores (PRSs), indicating that OPCs are involved in the genetic risk mechanisms and disturbed plasticity underlying SZ. In patients with multiple sclerosis, 90 days' administration of clemastine fumarate 10.72 mg/day, corresponding to clemastine 8 mg/day, significantly decreased the P100 latency delay of visual evoked potentials (VEPs) as a sign of myelin repair. In a bicentric, randomized, double-blind, controlled phase IIb clinical trial with a 2-arm parallel group design in patients with SZ, the study will compare the effects of aerobic exercise training plus clemastine vs. aerobic exercise training plus placebo over a period of 3 months on 1) everyday functioning and 2) working memory as primary outcomes.
The goal of this clinical trial is to test the performance of neuronal networks trained on ultrasonic raw Data (=radiofrequency data) for the assessment of liver diseases in patients undergoing a clinical ultrasound examination. The general feasibility is currently evaluated in a retrospective cohort. The main questions the study aims to answer are: - Can a neuronal network trained on RF Data perform equally good as elastography in the assessment of diffuse liver diseases? - Can a neuronal network trained on RF Data perform better than a neuronal network trained on b-mode images in the assessment of diffuse liver diseases? - Can a neuronal network trained on RF Data distinguish focal pathologies in the liver from healthy tissue? To answer these questions participants with a clinically indicated fibroscan will undergo: - a clinical elastography in Case ob suspected diffuse liver disease - a reliable ground truth (if normal ultrasound is not sufficient e.g. contrast enhanced ultrasound, biopsy, MRI or CT) in case of focal liver diseases, depending on the standard routine of the participating center - a clinical ultrasound examination during which b-mode images and the corresponding RF-Data sets are captured
The goal of this clinical trial is to test the impact of a detailed treatment handbook and follow-up schedule on women seeking care for chronic pelvic pain in a gynecology office-based practice. The main questions it aims to answer are: - How does the handbook and follow-up impact patient satisfaction? - How does the handbook and follow-up impact patient pain and quality of life scores? Participants will be randomized to receive the office standard of care, or standard of care plus a printed handbook customized to highlight their diagnosis, treatment plan and follow-up schedule.
This study is going to compare different teaching strategies for improving newly recruited nurses' comprehensive nursing assessment skills.
This is a Phase I clinical study designed to evaluate the safety, tolerability, and pharmacokinetics, and preliminary efficacy of SCTB35 monotherapy, an bispecific antibody, in patients with relapsed and/or refractory B-cell non-Hodgkin lymphoma.
the aim of the study is to evaluate the efficacy of guided biofilm therapy (GBT) for treatment of deep periodontal pockets. the objectives are 1- To compare the change in the clinical periodontal parameters and microbiological parameters by using real time PCR for P. gingivalis, Aggregatibacter actinomycetemcomitans and Filifactor alocis among sites treated by GBT and conventional hand instrumentation after a period of 3 months and to assess the level of the selected periodontal pathogens in deep periodontal pockets and to estimate and compare deep periodontal pockets which need surgery after 3 months of non-surgical treatment by GBT and conventional hand instrumentation. the hypothesis is whether there are no differences in in the clinical and microbiological parameters among sites treated by GBT and conventional hand instrumentation after a period of 3 months or there are differences in in the clinical and microbiological parameters among sites treated by GBT and conventional hand instrumentation after a period of 3 months. The participants will be selected on a consecutive basis from patients referred to the Department of Periodontics, College of Dentistry, University of Baghdad. For each patient, each site will be randomly assigned to either treatment protocol: 1. Sites treated with GBT. 2. Sites treated with conventional manual instrumentation only.
High-risk drinking is very prevalent among Danes aged 55+. It poses a serious risk to health and independent living, burdening health care systems and family members. Measures to reduce high-risk alcohol use in this growing group at need are urgently needed. A recent small study from the US shows that text messaging reduces high-risk alcohol intake in older adults. The investigators will conduct a pilot study with the same intervention in Denmark, with adaptations to language and culture. The pilot study will investigate among Danish older adults whether text messaging is well-accepted by participants and feasible in terms of reducing 1) high-risk drinking and 2) commonly accompanying problems with daily functioning, social relationships, and mental and physical health. The pilot-trial will include n=60 adults aged 55-80 years who will receive alcohol-related text messages (within a secure app for data protection purposes) over 12 weeks. Assessments will include a baseline assessment and a post-assessment.
STAMPEDE2 is a clinical trial comparing three new treatments with standard of care in people with prostate cancer that has spread to other parts of the body and is responsive to hormone therapy. People from all backgrounds and ethnicities are encouraged to take part and multiple hospitals across the UK are involved. University College London is running the trial. Each comparison within the trial has its own control arm where people get the best standard of care (Arm A) versus a research arm where a new treatment is added to standard of care. Participants are allocated to an arm by a computerised system with a 50% chance of getting the research treatment. Comparison S: Arm A versus Arm S (Stereotactic Ablative Body Radiotherapy (SABR)) - Tests whether giving targeted doses of radiotherapy (SABR) to parts of the body where the cancer has spread slows the spread of the cancer and improves survival. 2476 people will be in this comparison. Comparison P: Arm A versus Arm P (PSMA-Lutetium (177Lu-PSMA-617)) - Tests whether giving a radioactive material (177Lu-PSMA-617) that targets prostate cancer cells slows the spread of the cancer and improves survival. 1756 people will be in this comparison. Comparison N: Arm A(N) versus Arm N (Niraparib-Abiraterone Acetate+Prednisolone (Nira-AA+P)) - Tests whether giving a new drug (Nira-AA+P) slows the spread of the cancer and improves survival. Only people with certain genetic changes in their tumour sample can take part in Comparison N. 682 people will be in this comparison. Participants may be able to take part in more than one comparison. All participants will be followed up with scans and tests to monitor their cancer. Doctors will check for any side effects from the treatments. Treatments will be stopped if side effects are serious, or people no longer wish to take the treatments.
TQB2223 is a recombinant, fully human antibody that binds to lymphocyte activation gene-3 (LAG-3) and blocks the LAG-3/ major histocompatibility complex class II (MHC-II) interaction, thus allowing for increased T-cell proliferation and cytokine production. This is a phase Ib study aimed at evaluating the safety, tolerability, and immunogenicity characteristics of TQB2223 injection combined with AK105 injection in the treatment of advanced hepatocellular carcinoma.
