  • Evidence-based Practice for an Old Diabetic Patient with Frailty Syndrome

    ObjectiveTo provide the best evidence for an old diabetic patient who combined with frailty syndrome with the goal of glycemic control, treatment strategy and their prognosis. MethodsPubMed, MEDLINE (Ovid), EMbase, The Cochrane Library (Issue 11, 2015) and CNKI were searched from their inception to Nov. 2015, to collect evidence about the management of glycemic control. Evidences were analyzed by the way of evidenced-based criterions. ResultsOne clinical guideline, one meta-analysis, three RCTs, seven cohort studies and four case-control studies were included. Evidence showed that compared with patient uncombined with frailty, old diabetic patients with frailty had a higher prevalence of dementia, cardiovascular diseases and death; Aggressive glycemic control could not reduce the prevalence of cardiovascular events and the risk of death, while it could increase the risk of falling. Glycemic control was more comprehensive which would be taken frailty into consideration. Diet rich in protein (especially leucine), resistance exercise and reasonable medications based on comprehensive geriatric assessment were proved benefit for the old diabetic patient. ConclusionThe incidence of cardiovascular events, hypoglycemia and mortality are increased in this old diabetic patient who combined with frailty. Maintaining HbA1c around 7.5% is reasonable and diet with enough calorie and rich in protein (especially leucine), resistance exercises should be recommended for the person.

  • Analysis on the status and temporal trend of dementia burden in Guangzhou from 2008 to 2019 and burden attributable to smoking

    Objective To analyze the characteristic and temporal trend in mortality and disease burden of Alzheimer’s disease (AD) and other forms of dementia in Guangzhou from 2008 to 2019, and estimate the disease burden attributable to smoking to provide evidence for promoting local health policy of prevention and intervention of dementia. Methods Based on the data of Guangzhou surveillance point of the National Mortality Surveillance System (NMSS), the crude mortality, standardized mortality, years of life lost (YLL) of AD and other dementia were calculated. The indirect method was used to estimate years lived with disability (YLD) and disability-adjusted life years (DALY).The distribution and changing trends of the index rates were compared from 2008 to 2019 using Joinpoint Regression Program. Based on the data of Guangzhou Chronic Disease and Risk Factors Monitoring System in 2013, the indexes of disease burden of AD and other forms of dementia attributable to smoking in 2018 was calculated. Results The standardized mortality rate, YLL rate, YLD rate and DALY rate of AD and other forms of dementia in Guangzhou increased from 0.45/100 000, 0.05‰, 0.02‰ and 0.07 ‰ in 2008 to 1.28/100 000, 0.15‰, 0.07‰ and 0.22‰ in 2019, respectively. The average annual changing trend was statistically significant (AAPC=11.30%, 13.09%, 13.09%, 13.09%, P<0.001). In most years, the mortality and disease burden of women were higher than those of men, but men had higher growing trend than women in standardized mortality rate, YLL rate, YLD rate and DALY rate from 2008 to 2019, with a slower growing speed after the year 2012.The disease burden of dementia attributable to smoking in men was significantly higher than that in women. Conclusion The mortality and disease burden of AD and other forms of dementia in Guangzhou have dramatically increased over the past twelve years. Intervention against modifiable factors such as smoking, and prevention and screening for dementia in key populations should be strengthened. Support policies for dementia care management should be adopted to reduce the disease burden caused by premature death and disability.

  • Effect of oral vitamin D on cognitive function: a meta-analysis

    Objective To systematically review the effect of vitamin D (VitD) supplementation on cognitive function in people with cognitive impairment and non-cognitive disorders. MethodsThe PubMed, Web of Science, Cochrane Library, EMbase, CBM, CNKI, WanFang Data and VIP databases were searched to collect randomized controlled trials (RCTs) about the effect of VitD supplementation on cognitive function of patients with cognitive impairment or non-cognitive disorders from inception to March, 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 software. Results A total of 19 articles including 8 684 cases were included. The results of meta-analysis showed that mini-mental state examination (MMSE) score (MD=1.70, 95%CI 1.20 to 2.21, P<0.01), Montreal cognitive assessment (MoCA) score (MD=1.51, 95%CI 1.00 to 2.02, P<0.01), Wechsler Adult Intelligence Scale-Revised (WAIS-RC) score (MD=9.12, 95%CI 7.77 to 10.47, P<0.01) and working memory (SMD=1.87, 95%CI 1.07 to 2.67, P<0.01) in the VitD group of patients with cognitive impairment were all better than those in the control group. However, the overall cognitive function and working memory of the non-cognitive impairment population were not significantly different compared with the control group. In terms of language fluency and language memory, there was no significant difference between the VitD group and the control group. In terms of the executive functions, at the intervention time of> 6 months, the VitD and control groups were statistically significant (SMD=0.15, 95%CI 0.01 to 0.28, P=0.03). Conclusion Current evidence suggests that VitD supplementation can effectively improve the overall cognitive function and working memory of patients with cognitive impairment, and has a positive effect on executive function at an intervention time of >6 months. Due to the limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusion.

  • Efficacy and safety of butylphthalide soft capsule in the treatment of vascular dementia: a meta-analysis

    ObjectivesTo systematically evaluate the efficacy and safety of butylphthalide soft capsule in the treatment of vascular dementia (VaD).MethodsDatabases including CNKI, WanFang Data, VIP, CBM, PubMed, EMbase, The Cochrane Library were electronically searched to collect randomized controlled trials of butylphthalide soft capsule in the treatment of vascular dementia published from September 2002 to July 2018. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.3 software.ResultsA total of 15 studies involving 1 149 patients were included. The butylphthalide soft capsule treatment group included 578 patients and the control group included 571 patients. The results of meta-analysis showed that compared with the control group (donepezil hydrochloride tablets or memantine hydrochloride tablets or EGb761 or negative control), the butylphthalide soft capsule treatment group improved the MMSE score of patients with VaD (MD=3.52, 95%CI 2.59 to 4.46, P<0.01), CDR score (MD=−0.72, 95%CI −0.80 to −0.65, P<0.01), and treatment efficiency (RR=1.31, 95%CI 1.20 to 1.43, P<0.01). However, there was no statistical difference in the number of adverse reactions between the treatment and control groups.ConclusionsButylphthalide soft capsule can be used in the treatment of patients with mild to moderate VaD. It can improve the cognitive function, raking of clinical dementia, and increase the effect rate of treatment. It can also work in conjunction with other drugs that improve cognitive function and no increase in adverse reactions has been found. However, due to the low quality of the included studies and small sample size, the actual efficacy strength is uncertain and the above conclusions are still required to be verified by more high-quality randomized controlled trials.

    ObjectiveTo systematically review the methodological quality of evidence-based guidelines on non-pharmacology management of behavioral and psychological symptoms of dementia, so as to provide references for taking caring for the dementia with behavioral and psychological symptoms. MethodsGuidelines concerning non-pharmacology treatment of behavioral and psychological symptoms were searched from websites of guideline development, websites of medical association and literature databases from inception to May 31st 2016. The methodological quality of included guidelines were evaluated according to the AGREE Ⅱ instrument, and the differences and similarities between recommendations of included guidelines were compared. ResultsA total of 544 literatures were identified and 6 of them were included. All the included guidelines were from abroad. The average scores of guidelines in six domains of AGREE Ⅱ were:scope and purpose 88.89%, stakeholder involvement 65.74%, rigor of development 63.72%, clarity of presentations 86.11%, applicability 50.69%, and independence 37.50%. The overall qualities of the included guidelines were grade B. The recommendations of the included guidelines were almost consistent. Recommended non-pharmacology management of behavioral and psychological symptoms of dementia included leisure and recreation activity, reminiscence therapy, behavioral therapy, training of caregivers, physical environment modification, animal-assisted therapy, massage, physical activity and patient-centered approach. ConclusionThe overall quality of included guidelines is relatively high. More efforts are needed to improve the applicability and independence of guidelines. There is still no local guideline concerning non-pharmacology recommendations on behavioral and psychological symptoms of dementia in China. It is suggested to develop guideline that is suitable for Chinese condition as soon as possible.
