Objective To systematically review the efficacy and safety of acupuncture for the treatment of tumor-related cognitive dysfunction. Methods The PubMed, The Cochrane Library, EMbase, CNKI, WanFang Data, VIP and CBM databases were electronically searched to collect studies on acupuncture for the treatment of tumor-related cognitive dysfunction from the establishment of the database to February 13th, 2022. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.4.1 software. Results A total of 16 studies involving 1 361 patients were included. The results of meta-analysis showed that the mini-mental state examination (MD=1.82, 95%CI 1.49 to 2.15, P<0.000 01) and Montreal cognitive assessment (MD=1.56, 95%CI 0.83 to 2.29, P<0.0001) scores of the acupuncture treatment group were superior to those in the control group. Furthermore, the acupuncture treatment group showed a reduced incidence of postoperative cognitive dysfunction (RR=0.50, 95%CI 0.39 to 0.63, P<0.000 01) and decreased levels of interleukin-6 (MD=−10.43, 95%CI −14.91 to −5.95, P<0.000 01), interleukin-1β (MD=−47.14, 95%CI −63.92 to −30.36, P<0.000 01), and tumor necrosis factor-α (MD=−9.13, 95%CI −12.38 to −5.89, P<0.000 01). In contrast, the visual analog scale score of the acupuncture treatment group (MD=−1.26, 95%CI −2.06 to −0.47, P=0.002) was better than that of the control group. No significant difference was found in the level of central nervous system-specific protein (S100β) (MD=−0.06, 95%CI −0.13 to 0.01, P=0.12) between the two groups. Conclusion Acupuncture therapy can improve tumor-related cognitive function in patients. Its curative effect is better than that of non-acupuncture therapy; however, its ability to reduce S100β levels is not significantly different from that of non-acupuncture therapy. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
Objective To systematically review the efficacy of six cognitive interventions on cognitive function of patients with mild cognitive impairment after stroke. Methods The PubMed, EMbase, Cochrane Library, SinoMed, WanFang Data and CNKI databases were electronically searched to collect randomized controlled trials on the effects of non-drug interventions on the cognitive function of patients with mild cognitive impairment after stroke from inception to March 2023. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Network meta-analysis was then performed using Openbugs 3.2.3 and Stata 16.0 software. Results A total of 72 studies involving 4 962 patients were included. The results of network meta-analysis showed that the following five cognitive interventions improved the cognitive function of stroke patients with mild cognitive impairment: cognitive control intervention (SMD=−1.28, 95%CI −1.686 to −0.90, P<0.05) had the most significant effect on the improvement of cognitive function, followed by computer cognitive training (SMD=−1.02, 95%CI −1.51 to −0.53, P<0.05), virtual reality cognitive training (SMD=−1.20, 95%CI −1.78 to −0.62, P<0.05), non-invasive neural regulation (SMD=−1.09, 95%CI −1.58 to −0.60, P<0.05), and cognitive stimulation (SMD=−0.94, 95%CI −1.82 to −0.07, P<0.05). Conclusion Five cognitive interventions are effective in improving cognitive function for stroke patients with mild cognitive impairment, among which cognitive control intervention is the most effective. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
ObjectiveTo systematically review the efficacy of cognitive behavioral therapy (CBT) for improving mental health and social functions in patients with multiple sclerosis (MS). MethodsWe searched PubMed, EMbase, The Cochrane Library (Issue 4, 2016), CBM and CNKI from inception to May 2016, to collect randomized controlled trials (RCT) about CBT on mental health and social function in patients with MS. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then meta-analysis was performed by using RevMan 5.3 software. ResultsA total of 11 RCTs involving 1 102 patients were included. The results of meta-analysis showed that, the HADS scores (depression: MD=-1.28, 95%CI-2.07 to-0.48, P=0.002; anxiety: MD=-1.52, 95%CI-2.99 to-0.06, P=0.04), BDI scores (MD=-9.11, 95% CI-15.82 to-2.40, P=0.008), HRDS scores (MD=-7.23, 95% CI-13.65 to-0.82, P=0.03), Chalder scores (MD=-4.88, 95% CI-6.61 to-3.16, P < 0.000 01), MFIS scores (MD=-2.98, 95% CI-4.52 to-1.44, P=0.000 2) and GHQ-12 scores (MD=-3.61, 95%CI-5.20 to-2.02, P < 0.000 01) in the CBT group were lower than that in the control group. No significant difference was found in WSAS scores (MD=-1.98, 95%CI-4.88 to 0.93, P=0.18) between two groups. ConclusionCBT may be effective for improving the negative mental experience, fatigue and quality of life in MS. No evidence to support CBT has benefits in social functions. Due to the limited quantity and quality of the included studies, the above conclusion needs to be verified by more high quality studies.
Objective To explore the characteristics of cognitive impairment in patients with alcohol dependence, and analyze the related influencing factors. Methods The Montreal Cognitive Assessment Scale (MoCA) was used to evaluate the cognitive function of 65 alcohol dependent patients hospitalized between January 1st and December 31st, 2014. The features of cognitive impairment and related influencing factors were analyzed. Results The differences of MoCA attention and delayed recall between different drinking year groups had statistical significance (P<0.05). The correlations of drinking year with MoCA attention (r=–0.250,P=0.044), and with delayed recall (r=–0.326,P=0.008) were both negative. MoCA scores, naming, attention and delayed recall were different statistically among different age groups (P<0.05). The correlations of ages with MoCA scores (r=–0.429,P<0.001), naming (r=–0.261,P=0.035), attention (r=–0.391,P=0.001) and delayed recall (r=–0.461,P<0.001) were all negative. MoCA scores, the visuoconstructional skills, language, abstraction and delayed recall were significantly different among different education level groups (P<0.05). The correlations of education level with MoCA scores (rs=0.650,P<0.001), the visuoconstructional skills (rs=0.540,P<0.001), language (rs=0.486,P<0.001), abstraction (r=0.602,P<0.001) and delayed recall (rs=0.593,P<0.001) were all positive. Ages had an effect on MoCA scores by multiple linear regression analysis (P<0.01). Conclusions For alcohol dependent patients with cognitive impairment, cognitive function is correlated with drinking year, age and education level. The cognitive function is much serious in patients with older age and longer drinking years. This kind of patients should be focused on and intervened early.
ObjectiveTo systematically review the associations of cognitive frailty with mortality and hospitalization in the elderly. MethodsThe VIP, PubMed, CNKI, WanFang Data, CBM, Embase, Cochrane Library and Web of Science databases were electronically searched to collect cohort studies on the association of cognitive frailty with mortality or hospitalization in the elderly from inception to May, 2023. Two reviewers independently screened the literature, extracted data and assessed risk of bias of the included studies. Meta-analysis was performed by R 4.2.2 software. ResultsA total of 19 cohort studies involving 63 624 elderly were included. The results of meta-analysis showed that compared with healthy elder, the elder with cognitive frailty had a higher mortality (OR=2.75, 95%CI 2.10 to 3.59, P<0.01) and hospitalization (OR=1.67, 95%CI 1.40 to 2.00, P<0.01). Subgroup analysis showed that cognitive frailty was related to the risk of death in different status of frailty and cognitive function, different assessment tools, different countries of development, different follow-up time and research sites. At the same time, different status of frailty and cognitive function and different levels of development of countries were related to the risk of hospitalization. ConclusionCurrent evidence shows that cognitive frailty can increase the risk of hospitalization and mortality in the elderly. It is suggested that early screening and intervention of cognitive frailty should be carried out to effectively reduce the risk of adverse consequences, so as to achieve healthy aging.
ObjectiveTo systematically review the influence of dexmedetomidine on early postoperative cognitive dysfunction in adult patients after receiving noncardiac surgery under general anesthesia. MethodsThe randomized controlled trials (RCTs) about the influence of dexmedetomidine on the early postoperative cognitive dysfunction of patients after receiving noncardiac surgery with general anesthesia was searched in PubMed, EBSCO, Springer, Ovid, The Cochrane Library (Issue 1, 2013), CNKI, VIP, WanFang Data and Google Scholar up to November 30th, 2013. The references of included literature were also retrieved manually. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of included studies. Then meta-analysis was performed using RevMan 5.2. ResultsA total of 22 RCTs involving 1 356 patients were enrolled. The results of meta-analysis indicated that:a) dexmedetomidine reduced the incidence of postoperative cognitive dysfunction on the first day (RR=0.38, 95%CI 0.29 to 0.49, P < 0.001), on the seventh day (RR=0.55, 95%CI 0.23 to 1.29, P=0.17); improved postoperative MMSE scores after surgery (on the first day:MD=2.38, 95%CI 1.42 to 3.34, P < 0.001; on the seventh day:MD=0.92, 95%CI 0.16 to 1.68, P=0.02), and decreased the expression of inflammatory factor IL-6 (instant:MD=-11.96, 95%CI-18.45 to-5.46, P=0.000 3; after 24 h:MD=-7.50, 95%CI-13.73 to-1.27, P=0.02); and TNF-α (instant:MD=-4.09, 95%CI-7.02 to-1.16, P=0.006)) in patients. b) No significant difference was found between two groups (MD=-0.97, 95%CI-2.37 to 0.43, P=0.17). ConclusionDexmedetomidine can effectively reduce the early-stage postoperative cognitive dysfunction, improve MMSE scores after the operation, and reduce inflammatory reaction. In addition, due to the limited quantity and quality of studies included, larger sample, high quality RCTs are needed to verify the abovementioned conclusion.
Objective To explore the correlation of protein and mRNA levels of monocyte chemotactic protein-1 (MCP-1) and serum amyloid A protein (SAA) with cognitive function in chronic obstructive pulmonary disease (COPD) patients with or without hypoxemia, in order to identify the serum indexes of early cognitive impairment in patients with COPD, and investigate the effect of hypoxemia on cognitive impairment. Methods Sixty-two COPD patients admitted in the respiratory department of Affiliated Hospital of North China University of Science and Technology from January 2013 to January 2017 were included in the study. The COPD patients were divided into a hypoxemia group (25 cases) and a non-hypoxemia group (37 cases) according to blood gas analysis. Meanwhile 30 healthy subjects were recruited as control. ELISA was used to measure the concentration of serum MCP-1 and SAA in all subjects, and RT-PCR was used to detect the mRNA expression of MCP-1 and SAA in peripheral blood mononuclear cells. Montreal cognitive assessment scale (MoCA scale) was used to determine cognitive function. The expression levels of MCP-1 and SAA were compared between three groups, and the correlations with cognitive dysfunction were analyzed. Results The expression levels of serum MCP-1 and SAA had the same trend as those of MCP-1 mRNA and SAA mRNA in peripheral blood in the COPD patients. The protein and mRNA levels of MCP-1 and SAA were higher than those in the healthy control group (all P<0.05). The COPD hypoxemia group and the COPD non-hypoxemia group were lower than the control group in MoCA score, and the MoCA score of the COPD hypoxemia group decreased more obviously (allP<0.05). The protein and mRNA levels of SAA and MCP-1 were negatively correlated with MoCA score (allP<0.05). Conclusion The protein and mRNA levels of MCP-1 and SAA in peripheral blood increase in COPD patients, and hypoxemia may be involved in cognitive dysfunction in COPD patients.
Frailty and cognitive impairment are two major risk factors for adverse outcomes in elderly patients with diabetes. In the elderly, physical frailty and cognitive impairment frequently coexist, and have similar pathophysiological pathways, so the new concept of " cognitive debilitation” has been proposed. Physical frailty and cognitive impairment could accelerate the decline of function among elderly diabetic patients, and seriously affect their quality of life. Early identification and appropriate intervention of cognitive frailty may improve the adverse outcomes of elderly patients with diabetes. This article reviews the research progress of cognitive frailty and senile diabetes.
Objective To construct an intervention program for postoperative fear of falling in elderly patients with hip fracture based on cognitive behavioral theory. Methods Based on cognitive behavioral theory and literature review, an initial draft of intervention plan for postoperative fear of falling in elderly patients with hip fracture was constructed. From January to March 2025, after two rounds of expert consultations and revisions, the final plan was formed. Results A total of 16 experts across the country were invited to participate in two rounds of Delphi expert consultations, covering areas such as orthopedic clinical nursing, orthopedic clinical medicine, nursing education, nursing management, rehabilitation therapy, and psychological therapy. The active participation rates for the two rounds of consultations were 94.12% and 100.00%, respectively. The expert authority coefficients were 0.860 and 0.907, respectively, and the Kendall harmony coefficients were 0.369 and 0.524, respectively. Ultimately, a program composed of 5 primary indicators (fall fear management team, fall fear management goals, fall fear assessment, fall fear intervention measures, and post-intervention effect evaluation), 17 secondary indicators, and 31 tertiary indicators was constructed. Conclusion The intervention program for postoperative fear of falling in elderly patients with hip fracture based on cognitive behavior theory constructed in this study is scientific and operable, which can provide reference and guidance for clinical nursing staff.
Objective To analyze a possible association of -A930G and C242T polymorphism with cognitive dysfunction in obstructive sleep apnea (OSA) patients, and assess potential interactions of CYBA alleles in OSA patients with cognitive dysfunction. Methods A total of 157 OSA patients with cognitive dysfunction were recruited as an experimental group, and 526 matched OSA patients without cognitive dysfunction as an control group. The neurocognitive assessment, polysomnography, genetic analyses, NADHP oxidase (NOX) activity, determination of urinary 8-OH-dG were completed in all subjects. Results Frequencies of the -930G allele carriers were not significantly different between two groups (P>0.05). Frequencies of the TT/CT genotypes were significantly higher in the OSA patients without cognitive dysfunction (P<0.05). NOX activity was assessed and found to be increased in the OSA patients with cognitive dysfunction (P<0.01). NOX activity was significantly higher in whom the allelic T variant was absent (P<0.05). The level of urinary 8-OH-dG was higher in the OSA patients with cognitive dysfunction (P<0.05). The level of urinary 8-OH-dG was significantly higher in whom the allelic T variant was absent (P<0.05). Conclusion The p22phox C242T polymorphism may be involved in the development of oxidative stress reaction in OSA patients with cognitive dysfunction.
