Occupational therapy interventions in promoting social communication skills among children with autism spectrum disorder: A scoping review

Rhaman N, A Rahman P

Med J Malaysia, 2024 Mar;79(Suppl 1):187-196.
PMID: 38555904

INTRODUCTION: Children with Autism Spectrum Disorder (ASD) often face significant challenges in verbal communication, social interaction, and exhibit repetitive behavioral patterns. These challenges persist across various developmental stages, particularly impacting their social communication abilities. This scoping review aims to explore the range of occupational therapy interventions that are employed to enhance social communication skills in children with ASD.
MATERIALS AND METHODS: A literature search was conducted independently on scientific databases: Scopus, Google Scholar, Science Direct, and Web of Science (WOS). The process was carried out according to the PRISMA guidelines.
RESULT: Of the 195 studies identified, 8 articles involving 185 participants, aged 17 months to 12 years old, across six countries met the inclusion criteria. The majority of studies indicate significant improvement in social communication abilities, while one study demonstrates insignificant results and another study presents mixed outcomes, utilising two different assessment tools.
CONCLUSION: Occupational therapy has showed promise in improving social communication in children with ASD. Nonetheless, this review emphasises the need for greater indepth study and long-term evaluation to better explain and sustain these benefits. More research is needed to develop OT interventions that are both effective and evidence-based.

Dengue serotype surveillance is important as any changes in serotype distribution may result in an outbreak or increase in severe dengue cases. This study aimed to determine circulating dengue serotypes in two hospitals in Selangor. Serum samples were collected from patients admitted for dengue at these two major public hospitals i.e. Hospital Sungai Buloh (HSB) and Hospital Tunku Ampuan Rahimah (HTAR) between November 2010 and August 2011 and subjected to real-time RT-PCR using SYBR® Green. All four dengue serotypes were detected in samples from both hospitals. The predominating serotype was dengue 1 in samples from both hospitals (HSB, DENV-1; 25.53 % and HTAR, DENV-1; 32.1 %).

Our group has previously reported the isolation, partial characterisation, and application of a Galbeta1-3GalNAc- and IgA1-reactive lectin from the seeds of champedak (Artocarpus integer). In the present study, we have subjected the purified lectin to reverse-phase high performance liquid chromatography and sequenced its subunits. Determination of the N-terminal sequence of the first 47 residues of the large subunit demonstrated at least 95% homology to the N-terminal sequence of the alpha chains of a few other galactose-binding Artocarpus lectins. The two smaller subunits of the lectin, each comprised of 21 amino acid residues, demonstrated minor sequence variability. Their sequences were generally comparable to the beta chains of the other galactose-binding Artocarpus lectins. When used to probe human serum glycopeptides that were separated by two-dimensional gel electrophoresis, the lectin demonstrated strong apparent interactions with glycopeptides of IgA1, hemopexin, alpha2-HS glycoprotein, alpha1-antichymotrypsin, and a few unknown glycoproteins. Immobilisation of the lectin to Sepharose generated an affinity column that may be used to isolate the O-glycosylated serum glycoproteins.
Fulltext Cross-sectional analysis of socioeconomic drivers of PM2.5 pollution in emerging SAARC economies

Within the intricate interplay of socio-economic, natural and anthropogenic factors, haze pollution stands as a stark emblem of environmental degradation, particularly in the South Asian Association for Regional Cooperation (SAARC) region. Despite significant efforts to mitigate greenhouse gas emissions, several SAARC nations consistently rank among the world's most polluted. Addressing this critical research gap, this study employs robust econometric methodologies to elucidate the dynamics of haze pollution across SAARC countries from 1998 to 2020. These methodologies include the Pooled Mean Group (PMG) and Augmented Mean Group (AMG) estimator, Panel two-stage least squares (TSLS), Feasible Generalized Least Squares (FGLS) and Dumitrescu-Hurlin (D-H) causality test. The analysis reveals a statistically significant cointegrating relationship between PM2.5 and economic indicators, with economic development and consumption expenditure exhibiting positive associations and rainfall demonstrating a mitigating effect. Furthermore, a bidirectional causality is established between temperature and economic growth, both influencing PM2.5 concentrations. These findings emphasize the crucial role of evidence-based policy strategies in curbing air pollution. Based on these insights, recommendations focus on prioritizing green economic paradigms, intensifying forest conservation efforts, fostering the adoption of eco-friendly energy technologies in manufacturing and proactively implementing climate-sensitive policies. By embracing these recommendations, SAARC nations can formulate comprehensive and sustainable approaches to combat air pollution, paving the way for a healthier atmospheric environment for their citizens.
