Purpose: Tic disorders (TD) are common neurodevelopmental disorders characterized by heterogeneous tic symptoms in children, making diagnostic classification difficult. This complexity requires accurate subtyping using data-driven computational methods to identify patterns within clinical data. This systematic review primarily summarizes the current evidence for the classification of TD using a data-driven approach.
Patients And Methods: We conducted a systematic literature search on PubMed and Web of Science up to December 2023 and identified 16 publications analyzing 14 unique samples, totaling approximately 6000 subjects.
Results: Nine studies classified different subtypes of TD based on symptoms and behavior. Seven studies identified novel factor structures based on TD and its complex comorbidity patterns. Seven studies highlighted associations between TD symptom patterns and genetics, reflecting the diversity of underlying genetic mechanisms underlying TD.
Conclusion: This systematic review reveals significant variability in research on the classification of TD, which limits the application of findings for accurate diagnosis and guiding treatment strategies in pediatric psychiatry. Further research incorporating multidimensional information (such as genetic, neuroimaging, and environmental and social factors) is essential to improve the understanding of TD subtypes.

Antithrombotic therapy in adults with ectatic coronary artery disease: a systematic review and network meta-analysis.
Egypt Heart J
January 2025
Tehran Heart Center, Cardiovascular Diseases Research Institute, Tehran University of Medical Sciences, North Kargar Ave, Tehran, Iran.
Background: Many studies have validated the use of antiplatelet or anticoagulant therapy in coronary artery ectasia (CAE) to reduce major adverse cardiovascular events (MACE); however, it is not completely known which group of these antithrombotic medications is more effective. The purpose of this systematic review and network meta-analysis was to evaluate the efficacy of different anti-thrombotic treatments in adult patients with CAE.
Methods: This systematic review and meta-analysis followed preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines as well as PRISMA extension statement for reporting of systematic reviews incorporating network meta-analyses and adhered to a registered predetermined methodology noted in the prospective register of systematic reviews (PROSPERO) protocol.
Factors Relating to Sprint Swimming Performance: A Systematic Review.
Sports Med
January 2025
Aquatics Lab, Department of Physical Education and Sports, Faculty of Sport Sciences, University of Granada, Granada, Spain.
Background: Swimming performance depends on a wide variety of factors; however, the interaction between these factors and their importance varies between events. In sprint events, the characterized pacing underlines its specific development, as swimmers must achieve the highest possible speed while sustaining it to the greatest extent possible.
Objectives: The aim of this review was to identify the key factors underlying sprint swimming performance and to provide in-depth and practical evidence-based information to optimize performance.
Efficacy of Ceftazidime-avibactam in treating Gram-negative infections: a systematic review and meta-analysis.
Eur J Clin Microbiol Infect Dis
January 2025
University of Sassari, Sassari, Italy.
Introduction: Ceftazidime-avibactam (CAZ-AVI) has emerged as a promising treatment option for Gram-negative infections, particularly those caused by CAZ-Non-Susceptible (NS) pathogens. This systematic review and meta-analysis aim to assess the efficacy and safety of CAZ-AVI in these challenging infections.
Methods: We systematically queried EMBASE, Cochrane CENTRAL, and PubMed/Medline for studies published until September 15, 2024.
Item-Level Analysis of Category Fluency Test Performance: A Systematic Review and Meta-Analysis of Studies of Normal and Neurologically Abnormal Ageing.
Neuropsychol Rev
January 2025
Department of Psychology, College of Health, Medicine and Life Sciences, Brunel University of London, Kingston Lane, Uxbridge, Middlesex, UB8 3PH, UK.
While Category Fluency (CF) is widely used to help profile semantic memory, item-level scoring (ILS) approaches to this test have been proposed to obtain indices that are less influenced by non-semantic supportive functions. We systematically reviewed the literature to test the hypotheses that (1) compared with healthy adults, individuals with a clinical diagnosis suggestive of neurodegeneration generate words of lower semantic complexity; (2) compared with young adults, older adults generate words of higher semantic complexity. We searched six databases (date of search: 8 December 2023) for studies that relied on CF and ILS methods, in normal ageing and in age-associated neurodegeneration.

January 2025
The Medical School, University of Sheffield, Beech Hill Road, Sheffield, S10 2RX, UK.
Purpose: Treating idiopathic Early Onset Scoliosis (idiopathic EOS) is challenging due to ongoing growth and extensive follow-ups. While bracing is effective for Adolescent Idiopathic Scoliosis (AIS), its value for children under 10 remains debated. This systematic review and meta-analysis evaluates the effectiveness of spinal bracing in idiopathic EOS, followed to skeletal maturity.
