Background: Preformed metal crowns (PMCs) have been used to restore carious primary molars and have a high success and survival rate. There are two methods currently employed for PMC placement - the conventional technique (CT) and Hall technique (HT).
Aim: This systematic review aims to compare the outcomes of PMCs placed using the CT and HT.
Design: This systematic review was conducted according to the Preferred Reporting Items for Systematic Review and Meta-analysis statement. A literature search of five databases was performed up to 23 August 2022. Clinical studies comparing carious primary molars restored with PMCs using either technique with a minimum 12-month follow-up were included. Risk of bias (RoB) assessment was performed using the National Institutes of Health Quality Assessment tool.
Results: Five articles met the inclusion criteria, and four were included for meta-analysis. The 12- and 24-month success and survival rates were above 85% for both groups, with no significant differences shown at 12 and 24 months. The HT requires a shorter treatment duration, is more cost-effective and has a high level of acceptability among parents when compared to the CT. Four articles were rated fair, and one article was rated good in the RoB assessment.
Conclusion: Greater consideration may be given towards using the HT as part of standard treatment procedures in managing carious primary molars. Future studies should standardise reporting of outcomes to facilitate a more homogeneous pool of data for future meta-analysis.

Background: Anaplastic lymphoma kinase (ALK)-positive primary CNS anaplastic large cell lymphoma (ALCL) is an extremely rare pediatric malignancy. Its radiological appearance often mimics infectious or glial lesions, complicating diagnosis and delaying treatment.
Observations: The authors report the case of a 10-year-old immunocompetent female who presented with absence seizures and vomiting.

Background: Youth mental health issues have been recognized as a pressing crisis in the United States in recent years. Effective, evidence-based mental health research and interventions require access to integrated datasets that consolidate diverse and fragmented data sources. However, researchers face challenges due to the lack of centralized, publicly available datasets, limiting the potential for comprehensive analysis and data-driven decision-making.

Background: Personalized Interactive Music Systems (PIMSs) are emerging as promising devices for enhancing physical activity and exercise outcomes. By leveraging real-time data and adaptive technologies, PIMSs align musical features, such as tempo and genre, with users' physical activity patterns, including frequency and intensity, enhancing their overall experience.
Objective: This exploratory systematic review and meta-analysis evaluates the effectiveness of PIMSs across physical, psychophysical, and affective domains.

Background: Postoperative swelling is a common complication after total knee arthroplasty (TKA), associated with pain, limited mobility, and delayed recovery. This study aimed to systematically review the literature on interventions that reduce postoperative swelling, categorized into preoperative, intraoperative, and postoperative phases.
Methods: A Preferred Reporting Items for Systematic Reviews and Meta-Analyses-compliant search of PubMed, Medline, Embase, and Cochrane databases was performed for clinical studies evaluating interventions to reduce swelling after primary TKA.

Introduction: Melatonin supplements and melatonin receptor agonists are linked to reduced delirium in the Intensive Care Unit (ICU) which we hypothesised may affect the length of stay (LOS) in ICU or in hospital. In this review, we identified and critically appraised the literature on the effect of exogenous melatonin and melatonin receptor agonists on the ICU and/or hospital LOS among adults admitted to the ICU.
Methods: Six electronic databases and three trial registries were searched for randomised controlled trials (RCTs).
