Introduction: With aging and growth of the population, the risk of cancer incidence and mortality is rapidly increasing. However, psychosocial treatment has been seriously neglected in many healthcare settings. Laughter therapy is a therapeutic program to improve emotional wellbeing and health which has been applied as a complementary treatment. We aim to explore effects of laughter therapy for patients with cancer on their negative emotions such as depression, anxiety, stress, pain, and fatigue. Methods: We searched the Cochrane Library, Embase, PubMed, Scopus, Web of Science, WANFANG data, Weipu (VIP), Chinese National Knowledge Infrastructure (CNKI) and independently rated the risk of bias in every article using the Cochrane Collaboration's Risk of Bias Assessment Tool. Review Manager and STATA software were used to pool the individually included studies. Results: Seven studies were found eligible to be included in the present review. Overall, study quality was relatively high. Our findings suggest that laughter therapy might have a positive effect on improving emotional response in cancer patients. Arguably, laughter therapy, whether humor or laughter, has a positive effect on anxiety, stress, pain feeling, fatigue, and depression in cancer patients. Conclusions: Laughter therapy is a convenient, multi-modality, flexible-duration therapy to improve negative emotions in cancer patients, regardless of their gender, age, and type of cancer.

Purpose: The objective of this study was to conduct the latest meta-analysis of randomized controlled trials (RCTs) that compare clinical results between surgery and conservative therapy of acute primary patellar dislocation (APPD), focusing on medial patellofemoral ligament (MPFL) reconstruction. Methods: We performed a literature search in Embase, The Cochrane Library, PubMed, and Medline to identify RCTs comparing APPD surgical treatment with conservative treatment from the establishment of each database to January 2019. The methodological quality of each RCT was assessed independently by the two authors through the Cochrane Collaboration's "Risk of Bias" tool. Mean differences of continuous variables and risk ratios of dichotomous variables were computed for the pooled data analyses. The I2 statistic and the χ2 test were used to evaluate heterogeneity, with the significance level set at I2 > 50% or P < 0.10. Results: Ten RCTs with a sum of 569 patients (297 receiving surgical treatment and 263 receiving conservative treatment) met the inclusion criteria for meta-analysis. Pooled data analysis showed no statistical difference in the field of subluxation rate, Kujala score, patient satisfaction, and frequency of reoperation between the two groups. Tegner activity score and recurrent dislocation rate in the conservative group were significantly higher than those in the surgically treated group. Conclusions: Conservative treatment may produce better outcomes than surgery for APPD in consideration of Tegner activity score. However, in view of limited research available, the interpretation of the discoveries should be cautious. More convincing evidence is required to confirm the effect of MPFL reconstruction.

• Multicomponent exercises enhance physical functions in frail elderly. • Significant improvement in Timed Up and Go Test times. • Enhanced physical performance scores with both short and long-term interventions. • Muscle strength, including handgrip and knee extensor, significantly increased. • No significant change in walking speed observed between groups. To assess the impact of multicomponent exercises on physical functions of frail elderly in communities, evaluating their effect on muscle strength, balance, and endurance, and their influence on quality of life. PubMed, Embase, Cochrane, and Web of Science were searched to collect relevant randomized controlled trials. The search cutoff date was January 24, 2024. Included studies met pre-specified inclusion and exclusion criteria. Data analysis was performed using Revman 5.4 and Stata 15.0 software. This analysis included 19 studies. After 12 weeks, the multicomponent exercises significantly enhanced participants' performance in various physical function assessments. Specifically, in the Timed Up and Go Test, the exercise group showed a significant reduction in time [SMD = -0.86 (95 % CI: -1.40 to -0.33)]. In the Short Physical Performance Battery, interventions shorter than 6 weeks significantly increased scores [SMD = 1.01 (95 % CI: 0.64 to 1.37)], and those longer than 6 weeks showed improvements [SMD = 0.53 (95 % CI: 0.26 to 0.80)]. Muscle strength also improved, with handgrip strength and knee extensor strength enhancements [SMD = 0.93 (95 % CI: 0.27 to 1.59); SMD = 0.72 (95 % CI: 0.24 to 1.20)]. However, there was no statistically significant difference in walking speed between the groups [SMD = 0.04 (95 % CI: -0.33 to 0.40)]. Although multicomponent exercises significantly improve muscle strength, balance, and endurance in frail elderly individuals, there is no conclusive evidence of their effect on enhancing quality of life or long-term health outcomes. Further research is needed to explore the specific impacts of different types and intensities of exercises on this population. [ABSTRACT FROM AUTHOR]
