Abstract
INTRODUCTION Due to the complicated surgical procedure of knee arthroplasty and low effectivity of hyaluronic acid (HA) in the treatment of knee osteoarthritis, various studies highly recommend the use of platelet-rich plasma (PRP). However, some studies also reported lower efficacy and limited use of PRP. AIM: To analyze systematically the different randomized controlled trials (RCTs) comparing the effectiveness of HA vs. PRP for the treatment of knee osteoarthritis. MATERIAL AND METHODS A systematic literature review was conducted using Medline and Central databases for RCTs about the comparison of HA vs. PRP for the treatment of knee osteoarthritis. Studies were included as per the PICOS criteria and relevant event data were extracted. Risk of bias was analyzed and a random-effects model was used to calculate the pooled odds ratio and risk ratio using RevMan software. RESULTS A total of 14 studies were included in the meta-analysis from year 2000 to 2021 including 613 patients. The current meta-analysis has a low risk of publication bias and we obtained the pooled odds ratio (OR) of 2.55 (95% CI: 1.35-4.84) with a τ (2) value of 1.01, χ (2) value of 52.79, I(2) value of 77%, Z value of 2.87 and p-value < 0.00001. The pooled risk ratio was 1.34 (95% CI: 1.09-1.65) with a τ (2) value of 0.09, χ (2) value of 73.48, I(2) value of 84%, Z value of 2.80 and p-value < 0.00001. CONCLUSIONS The current meta-analysis highly recommends the use of PRP for the treatment of knee osteoarthritis.

Abstract
BACKGROUND AND OBJECTIVES Transfusion-dependent β-thalassaemia can lead to severe psychological issues in paediatric and adolescent patients. However, the psychological interventions for these patients are limited in clinical practice. We aimed to investigate the impact of a 3-month psychological intervention on the quality of life (QOL) of children with β-thalassaemia (12-18 years old) who relied on blood transfusion in this study. MATERIALS AND METHODS In the current randomized controlled trial, a total of 143 paediatric or adolescent patients (12-18 years old) with transfusion-dependent β-thalassaemia were recruited. They were randomized into the control group (n = 71) who received standard physiological treatment and the intervention group (n = 72) who received a 3-month intervention in addition to standard physiological treatment. The effects of the interventions on the QOL and psychological outcomes of these participants were analysed. RESULTS The 3-month intervention significantly improved the scores of PedsQoL 4.0 Generic Core Scales of paediatric patients with transfusion-dependent β-thalassaemia. It also significantly improved the psychological status and alleviated the depression among children and adolescent patients by alleviating anhedonia, negative mood and negative self-esteem among them. CONCLUSION Psychological intervention has positive effects on the treatment for children with transfusion-dependent β-thalassaemia.
