Yellowstripe scad fish (YSF) or Selaroides leptolepis belongs to the small pelagic group that is abundantly found in South China Sea and is categorised as low value fishes. This study is designed to explore the physicochemical properties of YSF protein hydrolysate extracted using sodium phosphate buffer followed by 0.5%-2.0% of Alcalase at a series of hydrolysis time (1 hr and 2 hr). The properties of freeze and spray dried protein hydrolysate were evaluated for yield, degree of hydrolysis, protein content, microstructure and water holding capacity. Results showed that prolonged hydrolysis time exhibited increasing yield (0.6%-1.6% for spray drying and 12-16% for freeze drying) and high degree of hydrolysis (80-95%). Protein content recovered from hydrolysis process is within 20-29%. Microstructure of freeze dried YSF protein hydrolysate had ‘collapsed-building’ structure (irregular shapes with edges) while spray dried had small and spherical structure. Freeze dried protein hydrolysates were significantly (p

BACKGROUND: The present Malaysian healthcare system is burdened with increasing cases of non-communicable diseases (NCDs) and its risk factors. Health care providers (HCPs) have to provide both treatment and health education to ensure optimal outcome. Health education is a vital component in addressing and managing chronic diseases. This study intends to explore patient's perspective on health education services received from HCPs, focusing at the secondary triage in government primary healthcare facilities.
METHODS: This qualitative exploratory study focused on the health education component derived from a complex enhanced primary health care intervention. Participants were purposively selected from patients who attended regular NCD treatment at 8 primary healthcare facilities in rural and urban areas of Johor and Selangor. Data collection was conducted between April 2017 and April 2018. Individual semi-structured interviews were conducted on 4 to 5 patients at each intervention clinic. Interviews were transcribed verbatim, coded and analyzed using a thematic analysis approach.
RESULTS: A total of 35 patients participated. Through thematic analysis, 2 main themes emerged; Perceived Suitability and Preferred HCPs. Under Perceived Suitability theme, increased waiting time and unsuitable location emerged as sub-themes. Under Preferred HCPs, emerging sub-themes were professional credibility, continuity of care, message fatigue, and interpersonal relationship. There are both positive and adverse acceptances toward health education delivered by HCPs. It should be noted that acceptance level for health information received from doctors are much more positively accepted compared to other HCPs.
CONCLUSION: Patients are willing to engage with health educators when their needs are addressed. Revision of current location, process and policy of health education delivery is needed to capture patients' attention and increase awareness of healthy living with NCDs. HCPs should continuously enhance knowledge and skills, which are essential to improve development and progressively becoming the expert educator in their respective specialized field.

Cardiovascular diseases (CVDs) are silent killers and hyperlipidemia is a high-risk factor. Morinda citrolia leaf (MCL), which is commonly consumed by many cultural groups and has high level of catechins, might exert antihyperlipidemic properties. In this study, the catechins profile of MCL water extract was determined via HPLC and ultraperformance liquid chromatography-traveling wave ion mobility-quadrupole time of flight mass spectrometry (UPLC-TWIMS-QTOF). The major catechin in MCL and the most widely studied catechin with hypolipidemic activity, epigallocatechin gallate (EGCG), was studied in a cytotoxicity test on HepG2 cells prior the in vitro anti-hyperlipidemic assay. The total catechins of MCL reached 141.88 ± 5.04 mg/g, with catechin gallate (CG) (75.27 ± 8.49 mg/g) as the major catechin. Catechin derivatives that were identified include epigallocatechin-3-O-gallate (EGCG) with m/z 459.0912 [M + H]+, epigallocatechin (EGC) with m/z 307.0818 [M + H]+, CG with m/z 443.0976 [M + H]+, epigallocatechin(4β→8)-gallocatechin with m/z 649.0951 [M + K]+, and gallocatechin(4α→8)-epicatechin with m/z 633.1 [M + K]+. Cell inhibitions of MCL, CG and EGCG were more than IC50 of 100 μg/ml. MCL increased LDL-c uptake up to 1.11 ± 0.03-fold, but this was insignificant relative to control. CG and EGCG significantly increased LDL-c uptake up to 1.37 ± 0.19-fold and 1.59 ± 0.19-fold, respectively. Thus, MCL with CG has shown potential for modulating hyperlipidemia.

Proteins play a vital role in human development, growth, and overall health. Traditionally, animal-derived proteins were considered the primary source of dietary protein. However, in recent years, there has been a remarkable shift in dietary consumption patterns, with a growing preference for plant-based protein sources. This shift has resulted in a significant increase in the production of plant proteins in the food sector. Consequently, there has been a surge in research exploring various plant sources, particularly wild, and underutilized legumes such as Canavalia, Psophocarpus, Cajanus, Lablab, Phaseolus, and Vigna, due to their exceptional nutraceutical value. This review presents the latest insights into innovative approaches used to extract proteins from underutilized legumes. Furthermore, it highlights the purification of protein hydrolysate using Fast Protein Liquid Chromatography. This review also covers the characterization of purified peptides, including their molecular weight, amino acid composition, and the creation of three-dimensional models based on amino acid sequences. The potential of underutilized legume protein hydrolysates as functional ingredients in the food industry is a key focus of this review. By incorporating these protein sources into food production, we can foster sustainable and healthy practices while minimizing environmental impact. The investigation of underutilized legumes offers exciting possibilities for future research and development in this area, further enhancing the utilization of plant-based protein sources.

BACKGROUND: Amid the current burden of non-communicable (NCD) diseases in Malaysia, there is a growing demand for more efficient service delivery of primary healthcare. A complex intervention is proposed to improve NCD management in Malaysia. This exploratory study aimed to assess primary healthcare providers' receptiveness towards change prior to implementation of the proposed complex intervention.
METHOD: This study was conducted using an exploratory qualitative approach on purposely selected healthcare providers at primary healthcare clinics. Twenty focus group discussions and three in-depth interviews were conducted using a semi-structured interview guide. Consent was obtained prior to interviews and for audio-recordings. Interviews were transcribed verbatim and thematically analysed, guided by the Consolidated Framework for Implementation Research (CFIR), a framework comprised of five major domains promoting implementation theory development and verification across multiple contexts.
RESULTS: The study revealed via CFIR that most primary healthcare providers were receptive towards any proposed changes or intervention for the betterment of NCD care management. However, many challenges were outlined across four CFIR domains-intervention characteristics, outer setting, inner setting, and individual characteristics-that included perceived barriers to implementation. Perception of issues that triggered proposed changes reflected the current situation, including existing facilitating aspects that can support the implementation of any future intervention. The importance of strengthening the primary healthcare delivery system was also expressed.
CONCLUSION: Understanding existing situations faced at the primary healthcare setting is imperative prior to implementation of any intervention. Healthcare providers' receptiveness to change was explored, and using CFIR framework, challenges or perceived barriers among healthcare providers were identified. CFIR was able to outline the clinics' setting, individual behaviour and external agency factors that have direct impact to the organisation. These are important indicators in ensuring feasibility, effectiveness and sustainability of any intervention, as well as future scalability considerations.
