Filter by:Mood disorders, such as depression and bipolar disorder, are difficult to treat. One reason is that there are no objective ways to measure how these disorders affect the body and respond to different treatments. In this study, researchers want to perform tests on people undergoing clinical care for mood disorders. The purpose is to understand the experience of receiving treatment for depression, bipolar disorder, and suicide risk. We also hope that this study will help us to predict which medications will improve thoughts of suicide. People 18 years or older who are receiving treatment for depression, bipolar disorder, or suicide risk may take part in this study. Participants must have also been enrolled in protocol 01-M-0254. This study will be conducted at the NIH Clinical Center in Bethesda, MD. The study typically lasts up to 12 weeks, but may last longer if a participant s treatment continues past that time. Participants will have weekly interviews and questionnaires while they are being treated for their mood disorder. Other tests are optional and include psychological testing, blood draws, sleep tests, and imaging scans. These will be done at the start and the end of research participation....
Prospective observational study designed to describe the clinical, laboratory, imaging, microbiological characteristics and treatment of specific infectious diseases, with the addition of a dedicated biobank.
Non-randomized clinical trial conducted in the adult ICUs of Brazilian hospitals participating in the IMPACTO MR Platform, involving adult patients using an intracranial pressure monitoring catheter device or external ventricular drain. The study will test the hypothesis that the intervention bundle, following ANVISA recommendations for care practices, will reduce the rates of central nervous system infections associated with ICP and EVD devices. This reduction is expected to lead to more accurate diagnoses, decreased antibiotic usage, shortened ICU and hospital stays, and reduced hospital costs.
Resistant microorganisms are public health problems because they affect the treatment of infectious diseases and the survival of patients. Neurosurgical procedures with placement of intracranial pressure monitoring and external ventricular drainage devices are related to increased morbidity and mortality. In Brazil, there are several multicenter studies demonstrating the prevalence and types of resistant microorganisms, however, there is a lack of data related to central nervous system infections associated with invasive devices, which can have a direct impact on prevention and treatment policies.
Ventriculitis is a severe infectious disease of the central nervous system with diverse etiologies. Currently, the treatment for ventriculitis is challenging, with poor prognosis. The mortality rate of ventriculitis is generally reported to be higher than 30%, with the highest reaching over 75%. Even among survivors, over 60% suffer from a variety of neurological sequelae, including cognitive impairment, gait disturbances, paralysis, behavioral disorders, and epilepsy. Currently, treatments for ventriculitis recommended by guidelines primarily focus on the selection and administration of antibiotics, while the effects of surgical interventions have not been fully elucidated. In recent years, several studies have explored the use of ventricular irrigation in ventriculitis, indicating that ventricular irrigation techniques may accelerate the control of ventricular infection, mitigate damage to the central nervous system caused by infections, improve the prognosis of ventriculitis, and reduce complications such as hydrocephalus. However, current studies are still relatively scarce, and mostly case reports and retrospective studies. High-quality evidence is still lacking for the application of ventricular irrigation in ventriculitis. This multicenter randomized controlled trial aims to explore the safety and effectiveness of ventricular irrigation compared to conventional treatment for severe ventriculitis, analyze the effectiveness of ventricular irrigation across different pathogen subgroups, and investigate independent risk factors for different prognostic states in patients with severe ventriculitis.
This is a retrospective clinical study to analyze the clinical characteristics, complications, and effects of different treatment options on long-term prognosis in patients with central nervous system tuberculosis. All cases of central nervous system tuberculosis diagnosed between 2016 and 2021 were included in the electronic medical record system of one center, and data such as demographics, hospitalization information, clinical information, laboratory or imaging examinations, treatment plans, and outcomes were collected.
The aim of the current study was to assess the economic impact of using metagenomic next-generation sequencing (mNGS) versus traditional bacterial culture directed CNSIs diagnosis and therapy in post-neurosurgical patients from Beijing Tiantan Hospital. mNGS is a relatively expensive test item, and whether it has the corresponding health economic significance in the clinical application of diagnosing intracranial infection has not been studied clearly. Therefore, the investigators hope to explore the clinical application value of mNGS detection in central nervous system infection after neurosurgery.
Primary central nervous system vasculitis (CNSV) is a potentially fatal, single-organ vasculitis that often involves a spectrum of neurologic complications, including strokes, cognitive and speech impairment, visual loss, dementia, and encephalopathy. The purpose of this study is to establish a research cohort to investigate the disease process, treatments, and patient outcomes in CNSV.
Primary malignant central nervous system (CNS) tumors are the second most common childhood malignancies. Amongst, medulloblastomas are the most common malignant brain tumor of childhood and occur primarily in the cerebellum. According to molecular characteristics, medulloblastomas were classified into four subtypes: WNT, SHH, Group3 and Group4 and different prognosis were noticed between subgroups. Several genetic predispositions related to clinical outcome were also discovered and might influence the treatment of medulloblastomas as novel pharmaceutical targets. This study aims to investigate genetic and cellular profiles of pediatric brain malignancies, mostly medulloblastomas, and other central nervous system tumor based on WGS, RNA-seq, single-cell sequencing and spatial transcriptomics. We also aim to investigate the correlation between genetic characteristics and clinical prognosis.
Shoulder pain is a common musculoskeletal system complaint, accounting for 7-34% of patients in the clinic. The most common shoulder problem is subacromial impingement syndrome (SIS). Up to 45% of individuals with SIS may have unsuccessful treatment and still complain of symptoms after 2 years. This chronicity of pain may not be fully explained by structural injuries or damage, but may be related to sensorimotor changes. Decreased corticospinal excitability and increase inhibition have been found in individuals with SIS. These central motor changes may link to alteration in pain and nociception processing and the somatosensory system, which has been found in individuals with low back pain. Hyperalgesia has been found over both affected and unaffected shoulders in patients with SIS, indicating central and peripheral sensitization. However, no study has investigated whether there are changes in the central somatosensory system. Therefore, the objectives of this proposal are (1) to investigate the corticomotor and somatosensory system in patients with SIS (2) to investigate the relationship between the corticomotor and somatosensory alterations in patients with SIS. Subjects with chronic SIS and healthy subjects were recruited, with 32 people in each group. Electroencephalography (EEG) will be used to collect somatosensory activity, including somatosensory evoked potentials, spectral analysis of EEG oscillations and event-related spectral perturbation (ERSP) of the shoulder movement. Electromyography will be used to record muscle activity. Transcranial magnetic stimulation will be used to test corticomotor excitability, including active motor threshold, motor evoked potentials, cortical silent period, and intracortical inhibition and facilitation. The pressure pain threshold will be collected by a pressure algometer on the muscles of bilateral arms and legs. Pain intensity will be assessed with the Numeric Rating Scale. Shoulder function will be evaluated with the Disability of Arm, Shoulder and Hand questionnaire. Depression will be evaluated with Center for Epidemiologic Studies Depression Scale (CES-D).
