The present study was to examine the effect of stellate ganglion block (SGB) on bilateral regional cerebral oxygen saturation (rSO2) and postoperative cognitive function. Eighty patients undergoing selective coronary artery bypass graft with cardiopulmonary bypass (CPB) were randomly and equally divided into two groups. The patients in group S were given right SGB with ropivacaine, while the patients in group C were injected with normal saline. We compared the bilateral rSO2 after SGB. Minimum Mental State Examination (MMSE), Visual Verbal Learning Test (VVLT), and Digital Span Test (DST) were applied to observe the effect on cognitive function. We found that the incidence of postoperative cognitive dysfunction (POCD) 7 days after surgery in group S was lower than that in group C. The level of blocked side rSO2 of S group were significantly higher before CPB time of rewarming than that before SGB (P＜0.05), much higher than corresponding non-blocked side rSO2 before CPB (P＜0.05), and much higher than rSO2 level in group C before CPB and after CPB(P＜0.05). The non-blocked side rSO2 in group S before anesthesia were much lower than basic levels and those in group C (P＜0.05). It could be concluded from the above results that there was significant increase in the blocked-side rSO2 compared to the non-blocked side and there was significant decrease in the incidence of POCD compared to the control group after SGB.
China is facing the peak of an ageing population, and there is an increase in demand for intelligent healthcare services for the elderly. The metaverse, as a new internet social communication space, has shown infinite potential for application. This paper focuses on the application of the metaverse in medicine in the intervention of cognitive decline in the elderly population. The problems in assessment and intervention of cognitive decline in the elderly group were analyzed. The basic data required to construct the metaverse in medicine was introduced. Moreover, it is demonstrated that the elderly users can conduct self-monitoring, experience immersive self-healing and health-care through the metaverse in medicine technology. Furthermore, we proposed that it is feasible that the metaverse in medicine has obvious advantages in prediction and diagnosis, prevention and rehabilitation, as well as assisting patients with cognitive decline. Risks for its application were pointed out as well. The metaverse in medicine technology solves the problem of non-face-to-face social communication for elderly users, which may help to reconstruct the social medical system and service mode for the elderly population.
Chemotherapy-related cognitive impairment (CRCI) is one of the treatment-related side effects in cancer patients, which can reduce patients’ participation in medical decision-making and treatment, seriously affecting their daily function and quality of life. This article reviews the definition, research status, and influencing factors of CRCI in lung cancer patients, in order to provide basis and ideas for the subsequent evaluation and management of CRCI in lung cancer patients, and promote the optimization and improvement of the overall rehabilitation process of lung cancer patients.
We in the present research proposed a classification method that applied infomax independent component analysis (ICA) to respectively extract single modality features of structural magnetic resonance imaging (sMRI) and positron emission tomography (PET). And then we combined these two features by using a method of weight combination. We found that the present method was able to improve the accurate diagnosis of Alzheimer's disease (AD) and mild cognitive impairment (MCI). Compared AD to healthy controls (HC): the study achieved a classification accuracy of 93.75%, with a sensitivity of 100% and a specificity of 87.64%. Compared MCI to HC: classification accuracy was 89.35%, with a sensitivity of 81.85% and a specificity of 99.36%. The experimental results showed that the bi-modality method performed better than the individual modality in comparison to classification accuracy.
Objective To investigate the correlation between grip strength and subjective cognitive decline (SCD) in maintenance hemodialysis (MHD) patients of different genders. Methods Patients who underwent outpatient MHD in the Wenjiang Hemodialysis Unit, Department of Nephrology, West China Hospital, Sichuan University between March and June 2024 were selected as the research subjects. Multiple linear regression analysis was used to explore the relationship between grip strength and SCD in MHD patients of different genders. Results A total of 171 patients were investigated, with 76 in the non-SCD group and 95 in the SCD group. The results of multiple linear regression analysis showed that educational level (P=0.039), nutritional status (P=0.026), and grip strength (P=0.042) were the influencing factors of SCD in male MHD patients. Work status (P=0.001) and nutritional status (P=0.011) were the influencing factors of SCD in female MHD patients. Conclusions Educational level, nutritional status, and grip strength are influencing factors of SCD in male MHD patients. Work status and nutritional status are influencing factors of SCD in female MHD patients. Grip strength may serve as an indicator for evaluating SCD in male MHD patients.
Congenital heart disease (CHD) is a series of structural cardiac abnormalities resulting from abnormal fetal heart development. With the prolongation of survival time, their cognitive function problems begin to be concerned. From fetus period to adulthood, people with complex CHD are more likely to have abnormalities in brains. Children with complex CHD have a significantly increased risk of developmental disorders in cognitive functions, such as intelligence, attention and psychosocial disorders. These diseases persist into their adulthood. Adults with CHD have earlier neurocognitive decline, poorer performance in intelligence, executive function, attention and academic achievement, and are more likely to have mood disorders, higher incidence of mental disorders and lower quality of life. This paper reviews the studies on cognitive function of adult patients with CHD from the dimension of the whole life cycle.
