[PMID: 38696879 DOI: 10.1016/j.gerinurse.2024.04.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2024] [Revised: 04/10/2024] [Accepted: 04/18/2024] [Indexed: 05/04/2024]
Abstract
INTRODUCTION This study aimed to examine baseline risk factors in Alzheimer's Disease (AD) and Vascular dementia (VaD) patients with neuropsychiatry symptoms (NPS), and determine whether specific risk factors differ by subtypes of dementia for AD and VaD patients with NPS. METHODS A retrospective data analysis was conducted to evaluate similarities and differences in the risk factors for AD and VaD with NPS. The analysis included 2949 patients with VaD and 6341 patients with clinical confirmation of AD and VaD with or without NPS collected between February 2016 and August 2021. The multivariate logistic regression analysis was used to determine the risk factors associated with AD and VaD with NPS, by predicting the increasing odds (odds ratios (ORs) of an association of a specific baseline risk factor with AD or VaD with NPS. The validity of the regression models was tested using a Hosmer-Lemeshow test, while the Receiver Operating Curve (ROC) was used to test the sensitivity of the models. RESULTS In the adjusted analysis TSH (OR = 1.781, 95 % CI, p = 0.0025) and CHF (OR = 1.620, 95 %, p = 0.016) were associated with VaD with NPS, while a history of emergency department(ED) admission (OR = 0.277, 95 % CI, p = 0.003) likely to be associated with VaD patients without NPS. For AD patients, a history of CVA (OR = 1.395, 95 % CI, p = 0.032) and cancer (OR = 1.485, 95 % CI, p = 0.013) were associated with AD patients with NPS. DISCUSSION The findings of this study indicate that an abnormal thyroid gland and CHF were linked to VaD patients with behavioral disturbances, while CVA and cancer were linked to AD patients with behavioral disturbances. These findings suggest the need to develop management strategies for the care of patients with AD and VaD with NPS.

Abstract
OBJECTIVES To explore the effects of specialized nursing intervention based on quantitative evaluation strategy on the psychological state and quality of life of senile dementia patients. METHODS 92 senile dementia patients were divided into the control and intervention groups (n = 46 each). Control group was given routine nursing intervention, while intervention group was given specialized nursing intervention based on the quantitative evaluation strategy. Patients' self-care ability, cognitive function, nursing compliance, psychological state, quality of life, and patient satisfaction indexes were measured. RESULTS After nursing interventions, the self-care ability (71.73 ± 4.31 vs 63.82 ± 3.97 points) and cognitive functions such as orientation (7.96 ± 1.02 vs 6.53 ± 1.15), memory (2.16 ± 0.39 vs 1.69 ± 0.31), visual-spatial copying (3.78 ± 0.53 vs 3.02 ± 0.65), language skills (7.49 ± 1.26 vs 6.05 ± 1.28), and recall ability (2.13 ± 0.26 vs 1.75 ± 0.28) were significantly improved in the intervention group compared to the control group (P ˂ 0.05). The patient's compliance in the intervention group (95.65%) was prominently higher than the control group (80.43%) (P < 0.05). Notably, patient's psychological state (anxiety and depression) in the intervention group (47.42 ± 3.12 vs 51.39 ± 3.16, 48.52 ± 2.51 vs 52.83 ± 2.49) was better than the control group (P < 0.05). Furthermore, the quality of life was significantly improved in the intervention group (88.11 ± 1.11 vs 71.52 ± 1.24) compared to the control group (P < 0.05). Also, patients' satisfaction with nursing services in the intervention group (97.83%) was higher than the control group (78.26%) (P < 0.05). CONCLUSIONS Specialized nursing intervention based on quantitative evaluation strategy can effectively improve patients' self-care ability, and cognitive function, reduce anxiety and depression and enhance the quality of life, which is worthy of clinical promotion and application.

Abstract
Background Ferroptosis is a newly defined form of programmed cell death and plays an important role in Alzheimer's disease (AD) pathology. This study aimed to integrate bioinformatics techniques to explore biomarkers to support the correlation between ferroptosis and AD. In addition, further investigation of ferroptosis-related biomarkers was conducted on the transcriptome characteristics in the asymptomatic AD (AsymAD). Methods The microarray datasets GSE118553, GSE132903, GSE33000, and GSE157239 on AD were downloaded from the GEO database. The list of ferroptosis-related genes was extracted from the FerrDb website. Differentially expressed genes (DEGs) were identified by R "limma" package and used to screen ferroptosis-related hub genes. The random forest algorithm was used to construct the diagnostic model through hub genes. The immune cell infiltration was also analyzed by CIBERSORTx. The miRNet and DGIdb database were used to identify microRNAs (miRNAs) and drugs which targeting hub genes. Results We identified 18 ferroptosis-related hub genes anomalously expressed in AD, and consistent expression trends had been observed in both AsymAD The random forest diagnosis model had good prediction results in both training set (AUC = 0.824) and validation set (AUC = 0.734). Immune cell infiltration was analyzed and the results showed that CD4+ T cells resting memory, macrophages M2 and neutrophils were significantly higher in AD. A significant correlation of hub genes with immune infiltration was observed, such as DDIT4 showed strong positive correlation with CD4+ T cells memory resting and AKR1C2 had positive correlation with Macrophages M2. Additionally, the microRNAs (miRNAs) and drugs which targeting hub genes were screened. Conclusion These results suggest that ferroptosis-related hub genes we screened played a part in the pathological progression of AD. We explored the potential of these genes as diagnostic markers and their relevance to immune cells which will help in understanding the development of AD. Targeting miRNAs and drugs provides new research clues for preventing the development of AD.

Abstract
INTRODUCTION Behavioral and psychological symptoms of dementia (BPSD) are symptoms of non-cognitive nature, which frequently develop during the course and different stages of dementia. The diagnosis of BPSD is complex due to symptom variety, and relies on detailed clinical evaluation and medical history. Accurate assessment of BPSD is crucial in order to tailor therapeutic intervention (non-pharmacological and pharmacological) for each individual and monitor patient response to therapy. AREAS COVERED This review encompasses the epidemiology, classification, assessment and etiology of BPSD, as well as their impact on caregiver distress, and gives an overview of current and emerging non-pharmacological and pharmacological therapeutic options, as well as potential BPSD biomarkers, in order to provide a framework for improving BPSD diagnosis and developing novel, targeted and specific therapeutic strategies for BPSD. EXPERT OPINION Due to the large heterogeneity of BPSD and of the fact that drugs available only alleviate symptoms, finding an adequate treatment is very challenging and often involves a polytherapeutic approach. Non-pharmacologic interventions have shown promising results in improving BPSD, however further research is needed to confirm their beneficial effects. Thus, the modification of pre-existancing as well as the development of novel pharmacologic and non-pharmacologic solutions should be considered for BPSD therapy.

Abstract
Neuropsychiatric symptoms of dementia (NPS) are a group of noncognitive symptoms that occur in over 90% of individuals with dementia. NPS seem to result from a complex interaction among various biological, psychosocial, and environmental factors, and they are associated with greater morbidity and mortality, higher caregiver burden and burnout, high risk of nursing home placement, and increased cost of care for patients with dementia. Use of standardized assessment tools like the Neuropsychiatric Inventory can assist with qualifying and quantifying NPS. In this review, the authors evaluate the evidence for efficacy and safety of nonpharmacological and pharmacological interventions for treating NPS, mostly based on published meta-analyses. Commonly prescribed medications include atypical antipsychotics, acetylcholinesterase inhibitors, memantine, antidepressants, and mood stabilizers. There are also limited data on cannabinoids, repetitive transcranial magnetic stimulation, and ECT in individuals with NPS. Available evidence indicates that several nonpharmacological interventions are beneficial in the management of NPS and are recommended as first-line treatments. Pharmacotherapy should be reserved for the treatment of more severe or refractory NPS or where nonpharmacological management is not feasible. Atypical antipsychotics have shown mostly modest benefit in reducing NPS, and their use is limited by their adverse effect profiles. Recent investigations suggest potential strategies for preventing or at least reducing the risk of dementia and NPS. The authors conclude with brief guidelines for clinical practice as well as future research.

Abstract
Introduction Alzheimer's disease is the most common dementia with clinical and pathological heterogeneity. Cuproptosis is a recently reported form of cell death, which appears to result in the progression of various diseases. Therefore, our study aimed to explore cuproptosis-related molecular clusters in Alzheimer's disease and construct a prediction model. Methods Based on the GSE33000 dataset, we analyzed the expression profiles of cuproptosis regulators and immune characteristics in Alzheimer's disease. Using 310 Alzheimer's disease samples, we explored the molecular clusters based on cuproptosis-related genes, along with the related immune cell infiltration. Cluster-specific differentially expressed genes were identified using the WGCNA algorithm. Subsequently, the optimal machine model was chosen by comparing the performance of the random forest model, support vector machine model, generalized linear model, and eXtreme Gradient Boosting. Nomogram, calibration curve, decision curve analysis, and three external datasets were applied for validating the predictive efficiency. Results The dysregulated cuproptosis-related genes and activated immune responses were determined between Alzheimer's disease and non-Alzheimer's disease controls. Two cuproptosis-related molecular clusters were defined in Alzheimer's disease. Analysis of immune infiltration suggested the significant heterogeneity of immunity between distinct clusters. Cluster2 was characterized by elevated immune scores and relatively higher levels of immune infiltration. Functional analysis showed that cluster-specific differentially expressed genes in Cluster2 were closely related to various immune responses. The Random forest machine model presented the best discriminative performance with relatively lower residual and root mean square error, and a higher area under the curve (AUC = 0.9829). A final 5-gene-based random forest model was constructed, exhibiting satisfactory performance in two external validation datasets (AUC = 0.8529 and 0.8333). The nomogram, calibration curve, and decision curve analysis also demonstrated the accuracy to predict Alzheimer's disease subtypes. Further analysis revealed that these five model-related genes were significantly associated with the Aβ-42 levels and β-secretase activity. Conclusion Our study systematically illustrated the complicated relationship between cuproptosis and Alzheimer's disease, and developed a promising prediction model to evaluate the risk of cuproptosis subtypes and the pathological outcome of Alzheimer's disease patients.

Abstract
OBJECTIVE Behavioral and psychological symptoms of dementia (BPSD) place a heavy burden on patients as well as caregivers. Recently, pain was identified as an important determinant of BPSD. However, it is not yet known what influence sex has on BPSD and pain. Thus, the present study aimed to identify possible associations between BPSD, pain, and sex. DESIGN A retrospective evaluation of cross-sectional data derived from the Services and Health for Elderly in Long-Term Care (SHELTER) Study database, a cross-national European study on nursing home residents. SETTING AND PARTICIPANTS The study involved 4156 residents who were assessed using the interRAI instrument for Long-Term Care Facilities. Included in the analysis were only patients with cognitive impairment (n = 2822) (67.9%) of which 712 (25.2%) were male and 2110 (74.8%) were female. METHODS Differences in prevalence were tested using the χ2 test while bivariate logistic regression models were used to evaluate factors associated with sex. RESULTS Men showed behavioral symptoms such as wandering, verbal and physical abuse as well as sexual uninhibited behavior significantly more often than women. Regarding psychiatric symptoms, only depression was significantly more frequent in women. Surprisingly, in the presence of pain these differences in BPSD incidence between men and women were no longer detectable. Logistic regression analysis showed that in women with dementia/communication problems, the presence of pain could be indicated by resistance to care, sleeping disorders, and possibly by the presence of delusions and anxiety whereas in men it was related to abnormal thought processes, and in both sexes to depression CONCLUSIONS AND IMPLICATIONS: From a clinical point of view, resistance to care and sleeping disorders in women and abnormal thought processes in men as well as depression in both sexes should be seen as indicators of possible underlying pain in noncommunicative people. Thus, knowledge of sex-specific BPSD presentations can improve pain management in this particularly patient group.

Abstract
BACKGROUND A potent acetylcholinesterase inhibitor, donepezil is a cognitive enhancer clinically used to treat neurodegenerative diseases. However, its complete pharmacological profile beyond cognition remains unclear. The zebrafish (Danio rerio) is rapidly becoming a powerful novel model organism in neuroscience and central nervous system drug screening. AIM Here, we characterize the effects of 24-h donepezil administration on anxiety-like behavioral and endocrine responses in adult zebrafish. METHODS We evaluated zebrafish anxiety-like behaviors in the novel tank, the light-dark and the shoaling tests, paralleled by assessing brain acetylcholinesterase activity and whole-body cortisol levels. RESULTS Overall, donepezil dose-dependently decreased zebrafish locomotor activity in the novel tank test and reduced time in light in the light-dark test, likely representing hypolocomotion and anxiety-like behaviors. Donepezil predictably decreased brain acetylcholinesterase activity, also increasing whole-body cortisol levels, thus further linking acetylcholinesterase inhibition to anxiety-like behavioral and endocrine responses. CONCLUSION Collectively, these findings suggest negative modulation of zebrafish affective behavior by donepezil, support the key role of cholinergic mechanisms in behavioral regulation in zebrafish, and reinforce the growing utility of zebrafish models for studying complex behavioral processess and their neuroendocrine and neurochemical regulation.

Abstract
BACKGROUND Behavioral and psychological symptoms of dementia (BPSD) are difficult to manage and associated with poor outcome. OBJECTIVES The aim of this study was to reach consensus on the use of antipsychotics in patients with BPSD in Spain. METHODS A qualitative, multicenter, two-round Delphi study was carried out, with the participation of specialists involved in the care of dementia patients throughout Spain. They completed a 76-item questionnaire related to the identification of BPSD, treatment with antipsychotics, follow-up of patients, barriers for the use of atypical antipsychotics, and effects of antipsychotics on quality of life. RESULTS A total of 162 specialists in neurology, psychiatry, and geriatrics (61% men) with a mean (SD) age of 45.9 (10) years participated in the study. Almost all participants (96.9%) strongly agreed that atypical antipsychotics are safer and better tolerated than typical antipsychotics. There was agreement on the importance to review the indication and dose of the antipsychotic drug at least every 3 months. There was consistent high rate of agreement on the beneficial impact of atypical antipsychotics on the quality of life of patients with dementia and their caregivers. A consensus was also reached on the need of detecting BPSD in patients with dementia as it decreases the quality of life of both patients and caregivers, and the need to routinely screen for dementia in elderly patients with no previous psychiatric history in the presence of suggestive symptoms of BPSD. Finally, the participants in the study agreed that administrative barriers for the prescription of atypical antipsychotics in Spain hinder the access to this drug group and favor the prescription of typical antipsychotics. CONCLUSIONS The participants in the study agreed that atypical antipsychotics should be preferred to typical antipsychotics in the management of BPSD. Wide consensus was reached about the importance of early identification of BPSD in persons with cognitive impairment, the use and management of atypical antipsychotic drugs and their favorable impact on patients and caregiver's quality of life.

Abstract
Smoking is a risk factor for dementia. Cognitive function can be partially restored after quitting smoking, but still lower than never smoked group. The underlying mechanisms still remain unclear. The effects of smoking cessation combined with cerebral chronic hypoperfusion (CCH) on cognitive function have never been described. Here, we established a cigarette smoking cessation model, a CCH model, and a cigarette smoking cessation plus CCH model. We investigated cognitive function in these models and the mechanisms of the neuroinflammation, nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing 3(NLRP3)/cysteine aspartate-specific proteinase (caspase-1)/interleukin- 1β (IL-1β) pathway, and eucaryotic initiation factor 2α (eIF2α) /autophagy pathway. We used morris water maze (MWM) and novel object recognition (NOR) test to evaluate cognitive function in rats. Nissl staining was performed to observe cell morphology in the hippocampal CA1 area. A neuroinflammatory marker (glial fibrillary acidic protein, GFAP) was assessed by Western blot analysis and immunohistochemistry staining. IL-1β levels were detected by ELISA. The protein levels of NLRP3/caspase-1/ IL-1β and eIF2α/autophagy pathway were evaluated by Western blot analysis. LC3 was assessed by immunofluorescence staining. CCH can affect cognitive function by influencing neuroinflammation, NLRP3/caspase-1/IL-1β pathway, and eIF2α/autophagy pathway. Past exposure to cigarette smoke can also affect cognitive function by influencing neuroinflammation and NLRP3/caspase-1/IL-1β pathway, which may be induced by smoking and may not be alleviated after smoking cessation. Past exposure to cigarette smoke does not influence autophagy, which may be increased by smoking and then decrease to normal levels after smoking cessation. Past exposure to smoking can further aggravate cognitive impairment and neuroinflammation in VaD animals: cognitive impairment induced by CCH via neuroinflammation, NLRP3/caspase-1/IL-1β, and eIF2α/autophagy pathway and cognitive impairment induced by past exposure to cigarette smoke via neuroinflammation and NLRP3/caspase-1/IL-1β pathway. The combined group had the worst cognitive impairment because of harmful reasons.
