    BACKGROUND: Eucheuma Cottonii is a type of red algae obtained from Sabah with main active component, sulfated polysaccharide or k-carrageenan.

    AIMS: The objective of this research was to evaluate the antioxidant, antibacterial and potential wound-healing properties in aqueous extraction of E cottonii in order to meet the increasing demand for halal and natural cosmeceutical products.

    METHODS AND RESULTS: Aqueous extract of E cottonii was investigated for active compounds by phytochemical screening and IR spectroscopy. Antioxidant activity was carried out using DPPH method, and the IC50 value was 1.99 mg/mL. Antibacterial activity was examined against Staphylococcus Aureus using Kirby-Bauer disk diffusion method and showed 10.03 ± 0.06 mm zone of inhibition, achieved by 200 mg/mL of extracts. A wound was made by skin excision of area around 100 mm2 on each mouse. Test group was treated with aqueous extract gel (10% w/w); meanwhile, the mice that were treated with honey acted as the positive control group and the untreated mice as negative control group. Results showed that the wound contraction rate inclined to aqueous extracts as compared to untreated group (P

    Secondary sea-blue histiocytosis occurs more frequently than the primary form and occurs consequent to a wide range of metabolic and haematologic disorders including thalassaemia. We report an 18-year-old Chinese boy with transfusion-dependent HbE-beta thalassaemia who complained of pain and swelling at the left iliac crest region for 2 months duration. Physical examination revealed pallor with hepatosplenomegaly. Local examination revealed a huge swelling 12 cm × 12 cm in diameter, firm in consistency and tender. Histopathological examination of the mass revealed an osteosarcoma. His bone marrow aspirate showed numerous sea-blue histiocytes, the cytoplasm of which was closely packed with fine granules that stained blue with May-Grunwald-Giemsa. The nuclei were centrally located in some cells and displaced towards the periphery in other cells. There was no malignant cell infiltration in the marrow. The case is reported due to the co-incidental dual pathology in our patient (HbE-beta thalassaemia and osteosarcoma) and the unusual bone marrow finding of numerous sea-blue histiocytes.

    Soil is considered to be a major reservoir of Burkholderia pseudomallei in the environment. This paper investigates soil physicochemical properties that may influence presence of B. pseudomallei in soil samples from small ruminant farms in Peninsular Malaysia. Soil samples were collected from the farms and cultured for B. pseudomallei. The texture, organic matter and water contents, pH, elemental contents, cation exchange capacities, carbon, sulfur and nitrogen contents were determined. Analysis of soil samples that were positive and negative for B. pseudomallei using multivariable logistic regression found that the odds of bacterial isolation from soil was significantly higher for samples with higher contents of iron (OR = 1.01, 95%CI = 1.00-1.02, p = 0.03), water (OR = 1.28, 95%CI = 1.05-1.55, p = 0.01) and clay (OR = 1.54, 95%CI = 1.15-2.06, p = 0.004) compared to the odds of isolation in samples with lower contents of the above variables. These three factors may have favored the survival of B. pseudomallei because iron regulates expression of respiratory enzymes, while water is essential for soil ecology and agent's biological processes and clay retains water and nutrients.

    The effect of milling time on the morphology, microstructure, physical and mechanical properties of pure Al-5 wt % Al₂O₃ (Al-5Al₂O₃) has been investigated. Al-5Al₂O₃ nanocomposites were fabricated using ball milling in a powder metallurgy route. The increase in the milling time resulted in the homogenous dispersion of 5 wt % Al₂O₃ nanoparticles, the reduction of particle clustering, and the reduction of distances between the composite particles. The significant grain refining during milling was revealed which showed as a reduction of particle size resulting from longer milling time. X-Ray diffraction (XRD) analysis of the nanocomposite powders also showed that designated ball milling contributes to the crystalline refining and accumulation of internal stress due to induced severe plastic deformation of the particles. It can be argued that these morphological and microstructural variations of nanocomposite powders induced by designated ball milling time was found to contribute to an improvement in the density, densification, micro-hardness (HV), nano-hardness (HN), and Young's modulus (E) of Al-5Al₂O₃ nanocomposites. HV, HN, and E values of nanocomposites were increased by ~48%, 46%, and 40%, after 12 h of milling, respectively.

    Thawed fresh frozen plasma (FFP) if not used within 6 h, may have to be discarded due to the risk of contamination and uncertainty about its quality. The main objective of this study was to evaluate the levels of coagulation Factor II (FII), Factor VIII (FVIII), fibrinogen and bacterial growth in thawed refrozen FFP. Thirty FFP samples were collected from healthy donors. FFP were thawed in water bath at 37 °C for 20-25 min. Approximately 10 mL of plasma from each FFP unit was tested for FII, FVIII, fibrinogen and sterility. The thawed FFP units were then kept at 4 °C for 6 h before being refrozen and stored at - 20 °C. Two weeks later, the refrozen FFP were thawed again and representative samples were analysed as before. There was a significant decline in the mean FVIII level, from 155.77% to 85.6% at second thaw. The mean FII level increased significantly from 74.9% to 82%, whereas the mean fibrinogen level fell from 3.34g/L to 3.28 g/L, but the decline was not statistically significant. There was no bacterial contamination in all samples at both time points. Refrozen plasma may be considered as an alternative to the storage of thawed unused FFP provided they are kept in a controlled environment to reduce wastage. These thawed refrozen FFP can be used later in bleeding cases like other FFP as the levels of FVIII are still within the standard haematology range (0.5-2 IU/mL) and above the minimal level of 30% coagulation factors required for adequate haemostasis.

    INTRODUCTION: Edible bird nest (EBN) is a natural food product produced from edible nest swiftlet's saliva which consists of glycoproteins as one of its main components; these glycoproteins contain an abundant of sialic acid. The dietary EBN supplementation has been reported to enhance brain functions in mammals and that the bioactivities and nutritional value of EBN are important during periods of rapid brain growth particularly for preterm infant. However, the effects of EBN in maternal on multigeneration learning and memory function still remain unclear. Thus, the present study aimed to determine the effects of maternal EBN supplementation on learning and memory function of their first (F1)- and second (F2)-generation mice.

    METHODS: CJ57BL/6 breeder F0 mice were fed with EBN (10 mg/kg) from different sources. After 6 weeks of diet supplementations, the F0 animals were bred to produce F1 and F2 animals. At 6 weeks of age, the F1 and F2 animals were tested for spatial recognition memory using a Y-maze test. The sialic acid content from EBN and brain gene expression were analyzed using HPLC and PCR, respectively.

    RESULTS: All EBN samples contained glycoprotein with high level of sialic acid. Dietary EBN supplementation also showed an upregulation of GNE, ST8SiaIV, SLC17A5, and BDNF mRNA associated with an improvement in Y-maze cognitive performance in both generations of animal. Qualitatively, the densities of synaptic vesicles in the presynaptic terminal were higher in the F1 and F2 animals which might derive from maternal EBN supplementation.

    CONCLUSION: This study provided a solid foundation toward the growing research on nutritional intervention from dietary EBN supplementation on cognitive and neurological development in the generation of mammals.

    Elder abuse and neglect (EAN) goes largely unrecognized and underreported globally by health care professionals. Despite acknowledging their role to intervene elder abuse, health care professionals lacked knowledge and skills in this issue. This is a single-blinded, three-armed, cluster randomized controlled trials aimed to evaluate the effectiveness of the face-to-face Improving Nurses' dEtection and managEment of elDer abuse and neglect (I-NEED) intensive training program and I-NEED educational video in improving primary care nurses' knowledge, attitude, and confidence to intervene EAN; 390 primary care nurses were randomized equally into two intervention groups-ITP group (intensive training program) and ITP+ group (intensive training program and educational video)-and a control group. The knowledge, attitudes, and confidence to intervene EAN were measured using questionnaires at four intervals during 6-month follow-up. A total of 269 primary care nurses participated in this study. There was a significant increase in knowledge, attitude, and confidence to intervene EAN immediately post intervention observed in both intervention groups compared to the control group (p < .001). At the end of sixth month, there was an increase of knowledge favoring ITP group than the ITP+ group (p < .001). There is, however, no significant difference in attitude score between ITP and ITP+ group. There is a significant difference of confidence to intervene among the participants between both intervention groups with ITP+ participants reporting higher scores post intervention (p < .05). An intensive training module improved the knowledge, attitude, and confidence to intervene EAN. Other co-existing barriers for abuse victims getting help, resources, policy, and law of EAN need further highlights.

    INTRODUCTION: Schizophrenia (SCZ) is a highly debilitating disease despite its low prevalence. The economic burden associated with SCZ is substantial and mainly attributed to productivity loss. To improve the understanding of economic burden of SCZ in the low- and middle-income country regions, we aimed to determine the economic burden of SCZ in Malaysia.

    METHODS: A retrospective study was conducted using a prevalence-based approach from a societal perspective in Malaysia with a 1 year period from 2013. We used micro-costing technique with bottom-up method and included direct medical cost, direct non-medical cost, and indirect cost. The main data source was medical chart review which was conducted in Hospital Kuala Lumpur (HKL). The medical charts were identified electronically by matching the unique patient's identification number registered under the National Mental Health Schizophrenia Registry and the list of patients in HKL in 2013. Other data sources were government documents, literatures, and local websites. To ensure robustness of result, probabilistic sensitivity analysis was conducted.

    RESULTS: The total estimated number of treated SCZ cases in Malaysia in 2015 was 15,104 with the total economic burden of USD 100 million (M) which was equivalent to 0.04% of the national gross domestic product. On average, the mean cost per patient was USD 6,594. Of the total economic burden of SCZ, 72% was attributed to indirect cost, costing at USD 72M, followed by direct medical cost (26%), costing at USD 26M, and direct non-medical cost (2%), costing at USD 1.7M.

    CONCLUSION: This study highlights the magnitude of economic burden of SCZ and informs the policy-makers that there is an inadequate support for SCZ patients. More resources should be allocated to improve the condition of SCZ patients and to reduce the economic burden.

    Recently, soybean tempeh has received great attention due to many advantages such as higher nutritional value, lower production cost, and shorter fermentation time. In this study, the in vivo hepatoprotective and antioxidant effects of nutrient enriched soybean tempeh (NESTE) were determined. NESTE fermentation process which involved anaerobic incubation was previously proclaimed to increase the content of amino acids and antioxidant properties remarkably. The evaluation of histological sections, serum biochemical markers (aspartate aminotransferase (AST), alanine aminotransferase (ALT), and cholesterol and triglycerides (TG)), liver immune response level (nitric oxide (NO)) and liver antioxidant level (superoxide dismutase (SOD), ferric reducing antioxidant power (FRAP), and malondialdehyde (MDA)) was conducted in order to compare the effects of nonfermented soybean extract (SBE) and fermented soybean extract (NESTE) on alcohol-induced liver damage in mice. Results demonstrated that 1000 mg/kg of NESTE can significantly reduce the levels of AST, ALT, cholesterol, TG, MDA, and NO. On the other hand, it also raised the level of SOD and FRAP. Furthermore, the histological examination on 1000 mg/kg NESTE treatment group showed that this extract was capable of recovering the damaged hepatocytes to their normal structures. Thus, it can be concluded that NESTE produced through fermentation process was able to enhance hepatoprotective and antioxidant effects in vivo.

    This quasi-experimental study examined the effect of Supporting Family Doctors to Address Elder Abuse (SAFE) educational intervention among family doctors practicing at public primary care clinics in Malaysia. SAFE is an intensive, multimodal, locally tailored, and culturally sensitive face-to-face educational intervention on elder abuse. A significant mean score improvement of knowledge [Baseline: 5.33 (SD:1.33) to 6-month post-intervention: 6.45 (SD: 1.35); p<0.001] and perceived behavioral control [Baseline: 50.83 (SD: 8.87) to six-month post-intervention: 56.16 (SD: 9.56); p<0.001] observed in the intervention group compared to the control group. No significant difference in attitude, subjective norm, and practice scores between the two groups over time. SAFE educational intervention for family doctors was effective to improve but not sustainable knowledge and perceived behavioral control toward elder abuse identification and management. We recommend SAFE educational intervention as part of the continuous medical education for family doctors supplemented with a change in organization and national policy.

    Our study aims at describing mortality among reported elder abuse experiences in rural Malaysia. This is a population-based cohort study with a multistage cluster sampling method. Older adults in Kuala Pilah (n = 1,927) were interviewed from November 2013 to May 2014. Mortality was traced after 2 years using the National Registration Department database. Overall, 139 (7.2%) respondents died. Fifteen (9.6%) abuse victims died compared to 124 (7.0%) not abused. Mortality was highest with financial abuse (13%), followed by psychological abuse (10.8%). There was a dose-response relationship between mortality and clustering of abuse: 7%, 7.7%, and 14.0% for no abuse, one type, and two types or more, respectively. Among abuse victims, 40% of deaths had ill-defined causes, 33% were respiratory-related, and 27% had cardiovascular and metabolic origin. Results suggest a link between abuse and mortality. Death proportions varied according to abuse subtypes and gender.

    Objective: The MINI International Neuropsychiatric Interview (MINI) is a short, structured diagnostic interview compatible with the Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV). It was designed for clinical practice, research in psychiatric, primary care settings and epidemiological surveys. This preliminary study aims to evaluate the reliability and validity of the Malaysian Version of MINI for Major Depressive Disorder and Generalized Anxiety Disorder symptoms criteria only.

    Methods: Six hours of MINI training was given as part of a National Health Morbidity Survey training program for layman interviewers (n=229) and three videos were prepared by an expert psychiatrist for inter-rater reliability purposes. Meanwhile, for validity purposes, the MINI was administered to patients with Major Depressive Disorder (n=30), Generalized Anxiety Disorder (n=20) and to a normal population (n=60), to conform against the Diagnostic and Statistical Manual of Mental Disorder (DSM-IV) that was administered by psychiatrists.

    Results: Overall the inter-rater reliability was satisfactory (0.67 to 0.85) and the concordance between the MINI’s and expert diagnoses was good, with kappa values of greater than 0.88.

    Conclusions: The Malay version of the MINI is adjusted to the clinical setting and for the assessment of positive cases in a community setting. Modifications were highlighted to correct any identified problems and to improve the reliability of the MINI for future research and clinical use.

    This study aimed to determine the primary care doctors' ability to recognize elder maltreatment and their intentions to report on such conditions. About 358 primary care doctors participated in this study. Outcomes were assessed using a validated five context-relevant clinical vignettes. Primary care doctor's recognition of sexual abuse was highest (91.0%); while the lowest (70.2%) in case signifying physical abuse. Despite being able to ascertain elder maltreatment, the intention to report the event is generally low even for cases exemplifying physical abuse, emotional abuse and neglect. However, intentions to report cases of sexual and financial abuse are 86.9% and 73.5% respectively. Findings highlighted the uncertainties of primary care doctors in distinguishing the clinical findings of non-accidental injuries and injuries due to acts of maltreatment. This provides support for educational intervention and guidelines or policies to improve the knowledge and skills of primary care doctors to intervene in elder maltreatment.
