This study is a prospective cohort study to investigate the differences in resting-state functional magnetic resonance imaging (fMRI) between elderly spinal surgery patients with postoperative delirium (POD) who either develop or do not develop long-term postoperative neurocognitive disorders (pNCD).
Anesthesia and perioperative Neurocognitive Disorders in the Elderly patients undergoing hip fracture Surgery platform trial (ANDES platform trial): A pragmatic multi-arm, adaptive, open label, multicenter randomized controlled platform trial to assess the effect of different enhance anesthesia technique in perioperative neurocognitive function, as compared to standard anesthesia care in the elderly patients undergoing hip fracture
The incidence of postoperative delirium in elderly patients is high, which can lead to long-term postoperative neurocognitive disorders. Its high risk factors are not yet clear. At present, there is a lack of early diagnosis and alarm technology for perioperative neurocognitive disorders, which can not achieve early intervention and effective treatment. By artificial intelligence and autonomously evolutionary neural network algorithm, relying on multi-source clinical big data, we explored the use of Bayesian network to optimize the anesthesia decision-making system in enhanced recovery after surgery, and established risk prediction model for perioperative critical events. It is expected that this method will also help to establish a risk prediction model for postoperative delirium and long-term postoperative neurocognitive disorders. This project plans to collect the perioperative sensitive parameters of anesthesia machine, multi-parameter monitor, EEG monitor,fMRI and HIS system, to explore the evolution process of data characteristics by feature fusion.We also plan to quickly screen key perioperative risk characteristics of postoperative delirium from massive clinical data through feature selection, to explore the high risk factors of long-term postoperative neurocognitive disorders developing from postoperative delirium. Finally, with multi-center intelligent analysis，the risk prediction model of postoperative delirium and long-term postoperative neurocognitive disorders will be constructed.
The incidence of MBI and the probability of progression to dementia are high. Early detection and intervention have important clinical significance to reduce the occurrence of dementia, delay the progression of dementia and promote healthy aging to active aging. The occurrence and development of NPS in MBI patients may be related to genetic and degenerative changes in the central nervous system. The evaluation of MBI patients is mainly based on neuropsychological tests, including NPS and cognitive function assessment. Landmark model is an effective tool for dynamic risk prediction of the progress of MBI. It can make dynamic prediction at different time points according to various existing measurement indicators of an individual and calculate the individual prediction probability, which is one of the best models for studying the outcome of disease at present. The Landmark model is applied to the elderly MBI population to study the influencing factors of normal aging, MBI and dementia and the probability of metastasis, which is a beneficial attempt to further advance the defense line of dementia. Personalized non-drug intervention is the preferred treatment for MBI, which mainly includes cognitive/emotional intervention, sensory stimulation, exercise therapy, etc. Currently, it is recommended to adopt diversified strategies to implement individualized precision treatment programs for patients. The hierarchical and classified health management of elderly MBI patients combined with health portrait technology is helpful to improve management efficiency and better meet the needs of personalized health management for the elderly.
Depression in neurocognitive disorders (Alzheimers' disease and related disoders) is a highly prevalent condition, especially in nursing homes. While it is associated with significant distress, the current conventional antidepressants have shown only modest efficacy and exposed to potentially severe side effects. Recent evidence suggests that nitrous oxide (N2O) in its most commonly used packaging of EMONO (Equimolar Mixture of Oxygen and Nitrous Oxide) has rapid antidepressant properties and a good safety profile. However, no study has investigating the antidepressant effect of EMONO in a population of depressed older adults with moderate to severe neurocognitive disorders in nursing homes. The principal goal of the PROTO-EHPAD study is to compare the changes in depressive symptoms in such individuals in a randomized controlled trial with a follow up period of 8 weeks, with a dosage escalation procedure.
The Sleep Optimization for Brain Health Outcomes in Older Surgical Patients (SLEEP-BOOST) is a pilot randomized, controlled, singled-blinded (participant) trial in major orthopedic joint surgery patients that will build on a previously clinically tested cognitive behavioral therapy for insomnia (CBT-I) mobile application paired with a wearable device (wrist actigraphy).
Perioperative neurocognitive impairment (PND) mainly includes acute postoperative delirium (POD) and persistent postoperative cognitive impairment (POCD), which are common postoperative complications in elderly patients. Perioperative neurocognitive impairment (PND) is attracting increasing attention, but its exact mechanism is still unclear. The diagnosis of PND lacks the gold standard, so it is difficult to determine the incidence rate. At present, the diagnosis is mainly conducted through the scale. Therefore, this study aims to explore the correlation between peripheral blood biomarkers and PND in elderly frail patients undergoing gastrointestinal surgery.
The development of biological biomarkers reflecting neuropathology has enhanced the diagnostic precision of Alzheimer's disease over the past decade, compared to the clinical diagnosis that suffers from low specificity. Patients undergoing evaluation in specialized memory clinics suspected of major or minor neurocognitive disorder are notably examined through a lumbar puncture to measure beta-amyloid 42, beta-amyloid 40, total tau, and phosphorylated tau in the cerebrospinal fluid (CSF). The purpose of this clinico-biological collection is to better characterize the existing biomarkers used in clinical practice, as well as the development of new diagnostic or prognostic biomarkers for neurodegenerative diseases causing neurocognitive disorder (Alzheimer's disease, Lewy body disease, frontotemporal lobar degeneration, in particular). The primary objective is to gain a better understanding of conventional biomarkers and to develop new diagnostic and prognostic biomarkers for neurocognitive diseases: establishing a prospective clinico-biological collection of patients evaluated in clinical practice for a neurocognitive disorder.
This study aimed to analyze the reliability and validity of the results of the new designed perioperative cognitive test network platform, and to judge the reliability and scientific nature of the perioperative cognitive test. And then to explore whether the perioperative cognitive test network platform can be used to evaluate the changes of perioperative cognitive function of patients.
