th
significant decreased in protein concentration (p<0.05) was observed after the lyophilization
process, 70% of the proteins were still remained after lyophilization, which suggested a stable
extracellular vesicles proteomic profile even after lyophilization.
DISCUSSION/CONCLUSION: EVs were successfully isolated and lyophilized although the
lyophilization process did affect the concentration of proteins. However, the phenotypic
characteristic of the EVs remains unchanged, and the analysis of proteomic profile suggested
a potential long-term storage of EVs in lyophilized form, which could lead to an off-the-shelf
product for future therapeutic applications.

INTRODUCTION: This study aims to evaluate the prevalence of metabolically healthy obese
(MHO) phenotype and examine the cardiometabolic risk factors (CRF) clustering among
metabolically unhealthy obese (MUO) schoolchildren.
METHODS: This study included cross-sectional baseline data of 193 Malay obese children
(BMI z-score > +2 SD) aged 8-16 years enrolled in the MyBFF@school programme. Metabolic
status was defined based on the 2018 consensus-based criteria with MHO children had no
CRF (HDL-cholesterol > 1.03 mmol/L, triglycerides ≤ 1.7 mmol/L, systolic and diastolic blood
th
pressure ≤ 90 percentile, and fasting plasma glucose ≤ 5.6 mmol/L). Those that did not meet
one or more of the above criteria were classified as MUO.
RESULTS: The prevalence of MHO was 30.1% (95% CI 23.7 – 37.1) among obese Malay
schoolchildren. The most common CRF among MUO children was high blood pressure (51.9%)
and was significantly higher among boys than in girls (p-value = 0.03). Clustering of CRF among
MUO was 65.2%, 28.1%, 5.9% and 0.7% for 1 CRF, 2 CRF, 3 CRF and 4 CRF respectively.
DISCUSSION/CONCLUSION: MHO children have a favourable metabolic profile when
compared to MUO children. Stratification based on metabolic health status could prove
useful in identifying high risk children.

INTRODUCTION: Response rate is important for measuring the validity of survey data Higher
response rates indicate better data quality. Survey response rates have been dropping in
recent years, but research is lacking on national surveys response rate in Malaysia. This study
examined the response rates in rural and urban areas in National Health and Morbidity Survey
(NHMS) 2019.
METHODS: The (NHMS) 2019, was a cross-sectional study with two-stage stratified random
sampling. This survey involved both urban and rural households in Malaysia. The response
