A scoping review of oral health outcomes for people with cerebral palsy

Altered expression of transfer RNAs and their possible roles in brain white matter injury

Transfer RNAs (tRNAs) can regulate cell behavior and are associated with neurological disorders. Here, we aimed to investigate the expression levels of tRNAs in oligodendrocyte precursor cells (OPCs) and their possible roles in the regulation of brain white matter injury (WMI). Newborn Sprague-Dawley rats (postnatal day 5) were used to establish a model that mimicked neonatal brain WMI. RNA-array analysis was performed to examine the expression of tRNAs in OPCs. psRNAtarget software was used to predict target mRNAs of significantly altered tRNAs. Gene ontology (GO) and KEGG were used to analyze the pathways for target mRNAs. Eighty-nine tRNAs were changed after WMI (fold change absolute ≥1.5, P  < 0.01), with 31 downregulated and 58 upregulated. Among them, three significantly changed tRNAs were identified, with two being significantly increased (chr10.trna1314-ProTGG and chr2.trna2771-ProAGG) and one significantly decreased (chr10.trna11264-GlyTCC). Further, target mRNA prediction and GO/KEGG pathway analysis indicated that the target mRNAs of these tRNAs are mainly involved in G-protein coupled receptor signaling pathways and beta-alanine metabolism, which are both related to myelin formation. In summary, the expression of tRNAs in OPCs was significantly altered after brain WMI, suggesting that tRNAs may play important roles in regulating WMI. This improves the knowledge about WMI pathophysiology and may provide novel treatment targets for WMI.

Oral health of individuals with cerebral palsy in Saudi Arabia: A systematic review

OBJECTIVE

This systematic review aimed to comprehensively summarize and critically assess studies conducted on oral health outcomes among individuals with cerebral palsy (CP) in Saudi Arabia.

METHODS

This study followed the Participants, Exposure, Control and Outcomes (PECO) framework to formulate a focused research question. We conducted an extensive literature search across multiple databases, including PubMed, Medline, Scopus and Embase, in addition to clinical trial registers. Inclusion criteria encompassed clinical studies conducted in either English or Arabic, focusing on CP as defined by the International Classification of Diseases 10 (ICD10), and examining various oral health conditions and parameters. Nonclinical studies, commentaries, other systematic reviews and letters to the editor were excluded. Data extraction included comprehensive information about the study characteristics, oral health outcomes (dental, oral or periodontal disease; changes in standardized indices; dental trauma and other types of oral diseases) and an assessment of the risk of bias using the Appraisal Tool for Cross-Sectional Studies (AXIS).

RESULTS

The initial search yielded a total of 879 articles, ultimately resulting seven studies that met our stringent inclusion criteria. All of these studies were conducted as cross-sectional investigations in different cities within Saudi Arabia. The sample sizes ranged from 46 to 400 participants, all falling within the age range of 2-18 years. Notably, the prevalence of dental caries among individuals with CP in these studies varied significantly, with rates ranging from 52.9% to as high as 98.6%. Additionally, a substantial portion of CP patients exhibited poor oral hygiene, with figures ranging between 34.6% and 66.2%, and dental trauma was reported in 47.5% of the cases. Moreover, these studies underscored the influence of motor function and intellectual disabilities on the oral health status of CP individuals. Furthermore, various secondary outcomes, including periodontal parameters and oral health-related quality of life, were also assessed. However, it is essential to acknowledge that several sources of bias were identified within these studies, raising questions about the generalisability of their findings.

CONCLUSION

In conclusion, the systematic review revealed a concerning pattern of high dental caries prevalence and other oral health issues among individuals with CP in Saudi Arabia. Nevertheless, the need for comparative studies between CP patients and those without CP is evident to establish a definitive understanding of the oral health status of CP individuals. Initiating early interventions such as oral hygiene education, preventive dentistry programs, and orthodontic interventions could potentially contribute to improved oral health outcomes for individuals with CP in Saudi Arabia.

Effects of Nonimmersive Virtual Reality Intervention on Children With Spastic Cerebral Palsy: A Meta-analysis and Systematic Review

ABSTRACT

This review aimed to assess the effectiveness of nonimmersive virtual reality intervention compared with traditional rehabilitation in improving the functions of the upper and lower limbs, balance, and social participation among children with spastic cerebral palsy. We used librarian-designed searches of 10 databases to identify research articles on randomized controlled trials that assessed the effectiveness of nonimmersive virtual reality in intervening spastic cerebral palsy patients up to April 15, 2023. Independent evaluation was conducted by two trained investigators using the evaluation criteria of randomized controlled trial quality indicated in the Cochrane Manual of Assessment "risk-of-bias tool." The Physical Therapy Evidence Database scale was used to evaluate the method and quality of the literature. Twenty-one research articles involving 779 patients with spastic cerebral palsy were included. Significant differences between the nonimmersive virtual reality rehabilitation and traditional rehabilitation groups were observed in all indicators, except for the Jebsen-Taylor Hand Function Test. Nonimmersive virtual reality intervention is effective in improving the function of the lower extremity, balance, and social participation in children with spastic cerebral palsy, but its effect on upper limb function is still controversial.
