ObjectiveTo evaluate the reasonableness of anticoagulation management strategy in patients after mechanical heart valve replacement. MethodsAll patients were followed and registered continually at outpatient clinic from July 2011 to February 2013, with a minimum of 6 months after surgery. Targeted international normalized rate (INR) 1.60 to 2.20 and warfarin weekly dosage adjustment were used as the strategy of anticoagulation management. Except bleeding, thrombogenesis and thromboembolism, time in therapeutic range (TTR) and fraction of TTR (FTTR) were adopted to evaluate the quality of anticoagulation management. ResultsA total 1 442 patients and 6 461 INR values were included for data analysis. The patients had a mean age of 48.2±10.6 years (14-80 years) and the following up time were 6 to 180 months (39.2±37.4 months) after surgery. Of these patients, 1 043 (72.3%) was female and 399 (27.7%) was male. INR values varied from 0.90-8.39 (1.85±0.49) and required weekly doses of warfarin were 2.50-61.25 (20.89±6.93 mg). TTR of target INR and acceptable INR were 51.1% (156 640.5 days/306 415.0 days), 64.9% (198 856.0 days/306 415.0 days), respectively. FTTR of target INR and acceptable INR were 49.4% (3 193 times/6 461 times), 62.6% (4 047 times/6 461 times). There were 8 major bleeding events, 7 mild bleeding events, 2 thromboembolism events, and 2 thrombogenesis in the left atrium. ConclusionIt is reasonable to use target INR 1.60-2.20 and warfarin weekly dosage adjustment for patients after mechanical heart valve replacement.
Objective To systematically evaluate the effects of psychotherapy for cancer patients with depression. Methods We searched The Cochrane Library, PubMed, EMbase, Chinese Biomedical Literature Database, Chinese Scientific Journals Full-text Database, and Chinese Journal Full-text Database up to October 2010 to identify randomized controlled trials (RCTs) comparing psychotherapy plus conventional treatment with conventional treatment alone. The data were analyzed by using RevMan 5.0 software. Results Eleven RCTs involving 1 670 participants were included. The results of meta-analyses showed: (1) A significant difference was found between psychotherapy plus conventional treatment and conventional treatment alone in decrease of depression score (SMD= – 0.40, 95%CI – 0.70 to – 0.11); (2) No difference was observed between the two groups in decrease of anxiety score (SMD= – 0.68, 95%CI – 1.37 to 0.01), but the result was changed when a sensitivity analysis was done (SMD= – 0.30, 95%CI – 0.52 to -0.08). Conclusion Compared with conventional treatment alone, psychotherapy combined with conventional treatment could improve depressive states in cancer patients, but the result still needs to be confirmed by high-quality and large-sample RCTs.
ObjectivesTo systematically review the prevalence of depression in the elderly in China.MethodsPubMed, Web of Science, CBM, CNKI, WanFang Data and VIP databases were electronically searched to collect cross-sectional studies on the prevalence of depression of Chinese elderly from January 2010 to July 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 22 cross-sectional studies involving 12 656 patients were included. Meta-analysis showed that the overall prevalence of depression in Chinese elderly was 25.55% (95%CI 19.81% to 31.29%). Subgroup analysis showed that the prevalence of females was higher than that of males; the prevalence in the north was higher than that in the south; the prevalence in rural areas was higher than that in cities; the prevalence of CES-D assessment scale was higher than that of GDS-30; the prevalence of depression increased annually of data collection.ConclusionThe prevalence of depression in the elderly (aged 60 years and above) in China is high. More attention should be paid to this situation and more psychological intervention should be provided to the elderly. Due to the limited quantity and quality of the included studies, more high-quality studies are required to verify the above conclusion.
Objective To evaluate the cost effectiveness of four different mechanisms clinical commonly used antidepressants, namely, amitriptyline, escitalopram, mirtazapine and venlafaxine in the treatment of moderate-severe depressive disorder in China and to provide clinicians with some advice. Methods We carried out the cost-effectiveness analysis of four antidepressants by establishing a decision tree model. The parameters uncertainty in the model was estimated through one-way sensitivity analysis. Results In terms of average cost-effectiveness ratio (CER), amitriptyline’s was 45.24 RMB, which was the lowest. And the CERs of mirtazapine, escitalopram and venlafaxine were 273.71 RMB, 332.00 RMB and 716.58 RMB, respectively. While in terms of incremental cost-effectiveness ratio (ICER), venlafaxine was excluded as the dominated strategy. When the threshold value of willingness to pay (WTP) was less than 3 420.92 RMB, amitriptyline was the most cost-effective; when the threshold value ranges between 3 420.92 RMB and 4 200 RMB, mirtazapine was the most cost-effective; and when the threshold value was over 4 200 RMB, escitalopram was the most cost-effective. In the one-way sensitivity analysis, when we changed the four kinds of drugs costs within a certain range, the results was not changed with the change of venlafaxine’s cost but changed with the other three drugs costs. Conclusion Clinicians may choose the most cost-effective therapy according to patients’ different WTP values. We suggests that health care institutions should encourage the use of escitalopram clinically and provide subsidies for patients so as to increase the overall society benefit.
This paper analyzed literatures on the specificity study of electroencephalogram (EEG) in the diagnosis of depression since 2010 to 2020, summarized the recent research directions in this field and prospected the future research hotspots at home and abroad. Based on databases of China National Knowledge Infrastructure (CNKI) and the core collection of Web of Science (WOS), CiteSpace software was used to analyze the relevant literatures in this research field. The number of relevant literatures, countries, authors, research institutions, key words, cited literatures and periodicals related to this research were analyzed, respectively, to explore research hotspots and development trends in this field. A total of 2 155 articles were included in the WOS database. The most published institution was the University of Toronto, the most published country was the United States, China occupied the third place, and the hot keywords were anxiety, disorder, brain and so on. A total of 529 literatures were included and analyzed in CNKI database. The institution with the most publications was the Mental Health Center of West China Hospital of Sichuan University, and the hot keywords were EEG signal, event-related potential, convolutional neural network, schizophrenia, etc. This study finds that EEG study of depression is developing rapidly at home and abroad. Research directions in the world mainly focus on exploring the characteristics of spontaneous EEG rhythm and nonlinear dynamic parameters during sleep in depressed patients. In addition, synchronous transcranial magnetic stimulation (TMS) and EEG technologies also attract much attention abroad, and the future research hotspot will be on the mechanism of EEG on patients with major depression. Domestic research directions mainly focus on the classification of resting EEG and the control study of resting EEG power spectrum entropy in patients with schizophrenia and depression, and future research hotspot is the basic and clinical EEG study of depressed patients complicated with anxiety.
Objective To assess the efficacy of acupuncture versus western medicine in the treatment of depression in China. Methods Randomized controlled trials (RCTs) involving acupuncture versus western medicine in the treatment of depression in China were identified from CNKI (1979 to 2007), VIP (1989 to 2007), WANFANG Database (1998 to 2007) and CBM (1978 to 2007). We also hand searched relevant journals and conference proceedings. Data were extracted and evaluated by two reviewers independently with a specially designed extraction form. The Cochrane Collaboration’s RevMan4.2.8 software was used for data analyses. Results A total of 8 trials involving 619 patients were included. Meta-analyses showed that the total effective rate in the acupuncture group was similar when compared with fluoxetine (RR 1.03, 95%CI 0.94 to 1.14), doxepin (RR 1.14, 95%CI 0.91 to 1.43), amitriptyline (RR 0.95, 95%CI 0.70 to 1.29) and venlafaxine (RR 1.02, 95%CI 0.90 to 1.16). As for the HAMD score at week 2, no significant difference was noted between acupuncture and fluoxetine (WMD 0.03, 95%CI -1.26 to 1.31) or amitriptyline (WMD –?0.33, 95%CI –?1.88 to 1.23); for the HAMD score at week 4, no significant difference was observed between acupuncture and fluoxetine (WMD –?0.24, 95%CI –?1.85 to 1.37) or amitriptyline (WMD –?0.57, 95%CI –?2.02 to 0.88); for the HAMD score at week 6, acupuncture also had similar effects to fluoxetine (WMD –?0.19, 95%CI –?1.51 to 1.13). In terms of the SDS scores at week 2, 4, 6 and 8, no significant differences were noted between acupuncture and fluoxetine. Two trials reported adverse events and these observed no adverse events in the acupuncture group, but 31 and 25 patients experienced adverse events in the western medicine groups of these two trials. Conclusion Acupuncture is not inferior to western medicine, and it is worth noting that acupuncture is associated with few adverse reactions. Further large-scale trials are required to define the role of acupuncture in the treatment of depression.
