Effect of acceptance and commitment therapy for depressive disorders: a meta-analysis.

OBJECTIVE: To systematically evaluate the effect of Acceptance and Commitment Therapy (ACT) on depressive disorders. METHODS: The electronic databases of Web of Science Core Collection, Pubmed, EMBASE, Cochrane Library, PsycInfo, CNKI, Wanfang and Weipu were used to select relevant publications. Screening, data extraction, and quality assessment were undertaken following PRISMA guidelines for preferred reporting of systematic reviews and meta-analysis. RevMan5.4 was used for meta-analysis. RESULTS: 11 studies with a total of 962 patients were included. Random-effects model analysis showed that ACT could effectively reduce the level of depressive symptoms in patients with depressive disorders (SMD = - 1.05, 95% CI: - 1.43-- 0.66, P < 0.00001), improve psychological flexibility (MD = 4.84, 95% CI: 2.70-6.97, P < 0.00001), and have good maintenance effect (SMD = - 0.70, 95% CI: - 1.15-- 0.25, P = 0.002). All differences were statistically significant. CONCLUSIONS: ACT not only improves depressive symptoms and psychological flexibility, but also has a good maintenance effect, and it is particularly effective in Chinese patients. Large randomized controlled trials are needed to validate the findings from this meta-analysis.

Cross-cultural adaptation and validation of the geriatric 8 screening tool in Chinese hospitalized older adults with cancer.

OBJECTIVES: To translate, cross-culturally adapt, and validate the Geriatric 8 (G8) questionnaire in Chinese hospitalized older adults with cancer. METHODS: The Chinese version of the G8 (C-G8) was produced following Brislin's guidelines. The psychometric properties of the C-G8 were evaluated among 296 eligible patients. RESULTS: The content validity index of the C-G8 was 0.8∼1 at the item level and 0.975 at the scale level. The C-G8 identified more frail individuals among these older (>75 years) participants compared to their younger (65∼75 years) counterparts (frailty prevalence: 87.1% vs. 70.9%, P=0.010). The convergent validity of the C-G8 was tested by correlating it with the FRAIL scale (r=-0.592, P<0.001). The C-G8 had a lower internal consistency (Cronbach's α coefficient=0.501) but higher test-retest reliability and inter-rater reliability (intraclass correlation coefficient=0.913 and 0.993, respectively, P<0.001). CONCLUSIONS: The C-G8 questionnaire presented acceptable validity and reliability and could be used in Chinese hospitalized older adults with cancer.

The Optimal Cut-off Value of Upper Arm Circumference and Calf Circumference for Assessing Sarcopenia Among Chinese Community-Dwelling Older Adults.

Objective: To explore the cut-off values and health evaluations of upper arm circumference (AC) and calf circumference (CC) on sarcopenia in Chinese community-dwelling older people. Methods: In this cross-sectional study, AC, CC, handgrip strength, muscle mass and gait speed were measured in 1537 Chinese community-dwelling older people in Sub-study 1. Correlation analysis, receiver operator characteristic curve (ROC curve) analysis, and consistency analysis were used for determination of AC and CC cut-off values for sarcopenia diagnosis (sarcopenia-AC and CC). Thereafter, 269 participants accepted additional assessments on physical function, body composition and muscle strength in Sub-study 2. T-test or Mann-Whitney U-test was used to explore the differential effects of sarcopenia-AC and CC on health indicators between sarcopenic and non-sarcopenic participants. Results: In Sub-study 1, the Area Under ROC (AUC) of AC and CC for sarcopenia screening were greater than 0.700 (P<0.05). The cut-off values, sensitivity and specificity of AC and CC on sarcopenia in males were 25.9 cm (86.0%, 83.6%) and 33.7 cm (90.7%, 81.4%) whereas in females were 26.5 cm (70.8%, 69.7%) and 33.0 cm (86.5%, 69.4%), respectively. In Sub-study 2, the participants with sarcopenia-AC or sarcopenia-CC showed lower muscle strength and lower fat and muscle mass than the ones without (P<0.05). Additionally, males instead of females with sarcopenia-AC or sarcopenia-CC showed worse performance in time-up and go test and 6-Minute Walk Test (P<0.05). However, the 30-second chair stand test was not different between participants with and without sarcopenia-AC or sarcopenia-CC in both sexes. Conclusion: We found accurate and Chinese population targeted cut-off values of AC and CC on sarcopenia diagnosis (25.9 cm and 33.7 cm in males; 26.5 cm and 33.0 cm in females) and a good evaluation effect of AC and CC on fat and muscle mass, muscle strength and physical functions in males, not females.

The transmission line foreign body detection algorithm based on weighted spatial attention.

Introduction: The secure operation of electric power transmission lines is essential for the economy and society. However, external factors such as plastic film and kites can cause damage to the lines, potentially leading to power outages. Traditional detection methods are inefficient, and the accuracy of automated systems is limited in complex background environments. Methods: This paper introduces a Weighted Spatial Attention (WSA) network model to address the low accuracy in identifying extraneous materials within electrical transmission infrastructure due to background texture occlusion. Initially, in the model preprocessing stage, color space conversion, image enhancement, and improved Large Selective Kernel Network (LSKNet) technology are utilized to enhance the model's proficiency in detecting foreign objects in intricate surroundings. Subsequently, in the feature extraction stage, the model adopts the dynamic sparse BiLevel Spatial Attention Module (BSAM) structure proposed in this paper to accurately capture and identify the characteristic information of foreign objects in power lines. In the feature pyramid stage, by replacing the feature pyramid network structure and allocating reasonable weights to the Bidirectional Feature Pyramid Network (BiFPN), the feature fusion results are optimized, ensuring that the semantic information of foreign objects in the power line output by the network is effectively identified and processed. Results: The experimental outcomes reveal that the test recognition accuracy of the proposed WSA model on the PL (power line) dataset has improved by three percentage points compared to that of the YOLOv8 model, reaching 97.6%. This enhancement demonstrates the WSA model's superior capability in detecting foreign objects on power lines, even in complex environmental backgrounds. Discussion: The integration of advanced image preprocessing techniques, the dynamic sparse BSAM structure, and the BiFPN has proven effective in improving detection accuracy and has the potential to transform the approach to monitoring and maintaining power transmission infrastructure.

Development and Validation of Estimation Equations for Appendicular Skeletal Muscle Mass in Chinese Community-Dwelling Older Adults.

Purpose: This study aimed to establish equations for estimating muscle mass through anthropometric parameters or together with physical function parameters in the community-dwelling older adults, providing a simple way of muscle mass assessment. Methods: In this cross-sectional descriptive study, a total of 1537 older adults were recruited from the community and accepted the measurements of height, weight, upper arm and calf circumferences, grip strength, and walking speed. Body composition including appendicular skeletal muscle mass (ASM) was measured using bioelectrical impedance analysis (BIA). Participants were randomly divided into the development or validation group. Stepwise multiple linear regression was applied to develop equations in the development group. Thereafter, Pearson correlation coefficients, Bland-Altman plots, paired t-test, intraclass correlation coefficient (ICC) and paired-samples t-tests were used to assess the validity of the equations. Results: All parameters were significantly correlated with ASM (r = 0.195~0.795, P < 0.001) except for the age in the validation group (P = 0.746). The most optimal anthropometric equation was: [adjusted R2 = 0.911, standard error of the estimate (SEE) = 1.311, P < 0.001]. Comparatively speaking, this equation showed high correlation coefficient (r = 0.951, P < 0.001) and ICC (ICC = 0.950, P < 0.001). No significant differences were found between BIA-measured ASM and the estimated ASM. The Bland-Altman plot showed that the mean difference between the estimated ASM and BIA-measured ASM was 0 kg and the limits of agreement of ASM was -2.70~2.60 kg. Furthermore, inclusion of physical function did not significantly improve the adjusted R2 and SEE. Conclusion: The anthropometric equation offers a practical alternative simple and dependable method for estimating ASM in community-dwelling older adults.

Effect of "maccog" TCM tea on improving glucolipid metabolism and gut microbiota in patients with type 2 diabetes in community.

Objectives: This work aimed to observe the effect of consuming Chinese herb tea on glucolipid metabolism and gut microbiota in patients with type 2 diabetes mellitus (T2DM). Methods: Ninety patients with T2DM were recruited from a community and randomly divided into the control group (CG) and intervention group (IG). CG maintained conventional treatment and lifestyle, and IG accepted additional "maccog" traditional Chinese medicine (TCM) tea (mulberry leaf, radix astragali, corn stigma, cortex lycii, radix ophiopogonis, and gynostemma) for 12 weeks. Glucolipid metabolism, hepatorenal function, and gut microbiota were then measured. Results: After the intervention, the decreases in fasting plasma glucose (FPG) and total cholesterol (TC) were greater (P<0.05) in IG than in CG, and those in glycosylated serum protein (GSP) were almost significantly greater (P=0.066) in IG than in CG. The total protein (TP), albumin (ALB), and creatinine (CREA) levels in IG were significantly lower and their decreases were larger in IG than in CG (P<0.05) after the intervention. The Ace and Chao1 indices in IG were slightly higher after the intervention (P=0.056 and 0.052, respectively) than at baselines. The abundance of Actinobacteria, Lachnospiraceae, Bifidobacteriaceae, and Phascolarctobacterium increased significantly after the intervention in IG (P<0.05), and the abundance was higher in IG than in CG (P<0.05 or P<0.1). The abundance of Clostridiales and Lactobacillales was negatively correlated with FPG (P<0.05), Clostridiales and Lachnospiraceae was negatively correlated with GSP (P<0.05), and Bacteroides/Firmicutes was positively correlated with both (P<0.05). No adverse event was observed during the intervention. Conclusions: Administration of "maccog" TCM tea for 12 weeks slightly improved glucolipid metabolism and significantly increased the abundance of beneficial gut microbiota in community patients with T2DM. The increase in beneficial bacteria abundance may be involved in the improvement of glucose metabolism indicators. In addition, this intervention is safe and feasible.

Cortisol stress reactivity moderates the effects of parental corporal punishment on Chinese preschoolers' executive function.

BACKGROUND: To date whether the effects of parental corporal punishment (CP) on executive function (EF) distinct components are different is less clear. Moreover, theory and empirical work suggest that physiological regulation system may help to explain the individual differences in the developmental outcomes associated with parental CP. OBJECTIVE: This study examined the effects of parental CP on Chinese preschoolers' EF and whether the cortisol stress reactivity would moderate such effects. PARTICIPANTS AND SETTING: One hundred and fifty-two preschool-aged children and their parents from Beijing China participated in the present study. METHODS: Parental CP was reported by fathers and mothers respectively in the first year of the study (2015, spring), and children's EF was assessed and salivary cortisol was collected in the second year (2016, spring). RESULTS: Both paternal and maternal CP were negatively correlated with children's EF one year later, and the relation between maternal, but not paternal CP and children's EF was moderated by cortisol stress reactivity. Specifically, compared to children with high cortisol stress reactivity levels, children with low cortisol stress reactivity levels who experienced maternal CP in the past year showed poorer global EF and working memory. CONCLUSIONS: Findings highlight the critical importance of examining the interactive effects of individual physiological level and environmental-level risks on young children's self-regulation outcomes.
