Objective To explore the correlation between traditional Chinese medicine (TCM) blood stasis pattern of coronary heart disease (CHD) and coronary angiography result, so as to screen dangerous patterns and provide evidence for the objectification of TCM pattern differentiation. Methods Literature on correlation between blood stasis pattern and coronary angiography results from January 1992 to May 2012 were searched in the following databases: China Academic Journal Network Publishing Database (CAJD), Chinese Biomedical Literature Database (CBM), China Doctor Dissertation Full-text Database (CDFD), Chinese Selected Master’s Theses Full-Text Databases (CMFD), PubMed and MEDLINE. According to the inclusion and exclusion criteria, literature screening, data extraction and methodological quality assessment of the included studies were conducted. Then meta-analysis was performed using RevMan 5.1 software. Results A total of 28 studies involving 4 901 patients were included. The results of meta-analysis showed that, there is a significant significance between blood stasis pattern and the following coronary angiography result, namely, number of culprit vessels (OR=1.38, 95%CI 1.08 to 1.77, Plt;0.05), severity of stenosis (OR=1.79, 95%CI 1.04 to 3.08, Plt;0.05), and Gensini score (OR=7.74, 95%CI 3.99 to 11.49, Plt;0.05). Conclusion Compared with other TCM patterns, CHD with blood stasis pattern easily tends to present multi-vessels lesions, more than 75% stenosis and higher Gensini score, indicating the condition of CHD with blood stasis pattern is more severe than with other patterns. Due to the discrepancy of pattern differentiation and the limited quality of original studies, this conclusion is insufficient to be fully applied into clinical practice, and more large scale and high quality clinical trials are required.
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.
Objective To investigate the status of frailty in patients with coronavirus disease 2019 (COVID-19), and to analyze the influence of COVID-19 disease on the prevalence of frailty. Methods This study was conducted using a cross-sectional survey method. COVID-19 patients admitted to a centralized isolation point in Guangzhou were selected for an questionnaire survey by “questionnaire star”, between November and December 2022. The questionnaire included the general information questionnaire, Tilburg Frailty Indicator (TFI), the COVID-19 symptom scale and Mental Resilience Scale (RS-11). Multi-model logistic regression analysis was used to explore the influence of COVID-19 on the occurrence of debilitation. Results A total of 667 questionnaires were distributed, of which 594 were valid, with an effective rate of 89.1%. There were 150 patients (25.3%) were frail, 444 patients (74.7%) were non-frail, and 51 patients (8.6%) were newly frail after infected COVID-19. The median TFI score before COVID-19 was 3 (2, 4) points, 16.7% (99/594) were in a weak state. The median TFI score after COVID-19 was 3 (2, 5) points, 25.3% (150/594) were in a weak state. There were statistically significant differences in TFI scores (Z=−6.596, P＜0.001) and the incidence of debilitation (χ2=351.648, P＜0.001) before and after COVID-19. The results of multivariate logistic regression analysis showed that after controlling disease factors, demographic factors and psychosocial factors, the score of the COVID-19 symptom score was always the influencing factor of COVID-19 patients. The overall change trend of COVID-19 symptom score was statistically significant (P<0.001). Conclusions The COVID-19 symptom score is an important risk factor or predictor of frailty in patients with COVID-19. As the level of COVID-19 symptom score increases, the risk of frailty in COVID-19 patients increases.
