STUDY DESIGN: This is a cross-sectional study.
METHODS: This study was completed alongside similar studies undertaken by the rest of the Gulf Cooperation Council (GCC) countries and led by Kingdom of Saudi Arabia (KSA). The study will allow further understanding of possible obstacles that may be encountered while implementing a nationwide prevention program. The 10-dimensional model of readiness had been developed by the World Health Organization (WHO) in collaboration with five countries (Brazil, The Former Yugoslav Republic of Macedonia, Malaysia, Saudi Arabia, and South Africa) through a five-stage process. Stakeholders and decision makers were invited to participate. Scores for each dimension were compared with those for the rest of the GCC countries.
RESULTS: The overall score of Kuwait was 39.17 out of 100. This was below the mean average score for the GCC countries (47.83). Out of the 10 dimensions, key informants scored the highest on legislation, mandates and policies (6.61). The lowest score was reported on attitudes towards CM prevention (1.94). Informal social resources (5.72) ranked the highest as compared to the rest of the GCC countries.
CONCLUSIONS: The readiness of Kuwait is weak on several dimensions and needs to be strengthened. Despite that, the country is moderately ready to implement large-scale evidence-based CM prevention programs because it is strong in the infrastructure of knowledge, legislation, mandates, and policies and informal social resources.
MATERIALS AND METHODS: This is an in vitro experimental study. PVF samples were collected from horseshoe crabs from beaches in Malaysia and the crude extract was prepared. DPSCs were treated with different concentrations of PVF crude extract in an 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay (cytotoxicity test). We choose two inhibitory concentrations (IC50 and IC25) and two PVF concentrations which produced more cell viability compared to a negative control (100%) for further tests. Quantitative analysis of the proliferation activity of PVF was studied using the AlamarBlue®assay for 10 days. Population doubling times (PDTs) of the treatment groups were calculated from this assay. Genotoxicity was evaluated based on the CA and Ames tests. Statistical analysis was carried out using independent t test to calculate significant differences in the PDT and mitotic indices in the CA test between the treatment and negative control groups. Significant differences in the data were P<0.05.
RESULTS: A total of four PVF concentrations retrieved from the MTT assay were 26.887 mg/ml (IC50), 14.093 mg/ml (IC25), 0.278 mg/ml (102% cell viability) and 0.019 mg/ml (102.5% cell viability). According to the AlamarBlue®assay, these PVF groups produced comparable proliferation activities compared to the negative (untreated) control. PDTs between PVF groups and the negative control were insignificantly different (P>0.05). No significant aberrations in chromosomes were observed in the PVF groups and the Ames test on the PVF showed the absence of significant positive results.
CONCLUSION: PVF from horseshoe crabs produced insignificant proliferative activity on treated DPSCs. The PVF was non-genotoxic based on the CA and Ames tests.
