    The relative viabilities of homozygous and heterozygous karyotypes were measured by making crosses between strains ofD. ananassae homozygous for ST or inverted gene orders in the second and third chromosomes. The strains utilized during the present study originated from widely separated localities in India, Kuala Lumpur and Kota Kinabaru, Malaysia and Chian Mai, Thailand. The presence of heterosis in many interpopulation crosses is evident from the results which show that the inversion heterozygotes formed by chromosomes coming from distant populations exhibit heterosis. On the other hand, heterosis is absent in two intrapopulation crosses. Thus the present results provide evidence that heterozygosis for many genes and gene complexes does produce high fitness without previous selectional coadaptation.

    Among dinoflagellates responsible for benthic harmful algal blooms, the genus Ostreopsis primarily described from tropical areas has been increasingly reported from subtropical and temperate areas worldwide. Several species of this toxigenic genus produce analogs of palytoxin, thus representing a major threat to human and environmental health. The taxonomy of several species needs to be clarified as it was based mostly on morphological descriptions leading in some cases to ambiguous interpretations and misidentifications. The present study aims at reporting a benthic bloom that occurred in April 2019 in Tahiti island, French Polynesia. A complete taxonomic investigation of the blooming Ostreopsis species was realized using light, epifluorescence and field emission electron microscopy and phylogenetic analyses inferred from LSU rDNA and ITS-5.8S rDNA regions. Toxicity of a natural sample and strains isolated from the bloom was assessed using both neuroblastoma cell-based assay and LC-MS/MS analyses. Morphological observations showed that cells were round to oval, large, 58.0-82.5 µm deep (dorso-ventral length) and 45.7-61.2 µm wide. The cingulum was conspicuously undulated, forming a 'V' in ventral view. Thecal plates possessed large pores in depressions, with a collar rim. Detailed observation also revealed the presence of small thecal pores invisible in LM. Phylogenetic analyses were congruent and all sequences clustered within the genotype Ostreopsis sp. 6, in a subclade closely related to sequences from the Gulf of Thailand and Malaysia. No toxicity was found on the field sample but all the strains isolated from the bloom were found to be cytotoxic and produced ostreocin D, a lower amount of ostreocins A and B and putatively other compounds. Phylogenetic data demonstrate the presence of this species in the Gulf of Thailand, at the type locality of O. siamensis, and morphological data are congruent with the original description and support this identification.

    INTRODUCTION: In recent years, many unresolved issues pertaining to house officers in Malaysia have led to a longer waiting time and a 'glut' of medical graduates with a surprising 20% dropout amongst those who join the housemanship programme. This appears to reflect the changing times, mindsets and work expectations of millennials who comprise this cohort reflecting a need to consider possibilities of career shifts especially so in these uncertain times. This study explores the perceptions, awareness and interest in alternative career options amongst recent graduates and house officers.

    MATERIALS AND METHODS: This was a study done between 2018 and 2019 using a questionnaire which was shared on various social platforms. Data analysis was done using Excel spreadsheet.

    RESULTS: A total of 450 house officers and 657 medical graduates responded. Expectedly 66.8% claimed lifelong passion whilst another 12.1% claimed family influence as their reason to do medicine. Most were aware of their career challenges and 40% of them were keen to consider career change and reskilling indicating a possible shift from traditional expectations of a medical career.

    CONCLUSION: Whilst medicine is often considered a true calling, current challenges will require mental and emotional flexibility to explore other career opportunities. Thus, engagement programmes should be directed at medical graduates and house officers to identify and support those open to career transitions. This will help address current issues of internship bottleneck and rising dropout rates amongst internees. Early career change engagements will give them insight into their true career goals whilst opening up opportunities for those who wish to change.

    The rise in obesity has fuelled the current debate of its classification as a disease. Contrary to just being a medical condition or a risk factor for other diseases, obesity is a complex disease with multifaceted aetiology as well as its own disabling capacities, pathophysiology, and comorbidities. The problem of obesity in Malaysia is serious and calls for active intervention by all stakeholders ranging from government agencies to insurers and healthcare providers. To aid efforts to curb obesity, this consensus statement for bariatric surgery provides a basis for inclusion and exclusion criteria as well as the types of procedures accepted as the norm in Malaysia. This consensus statement was initiated by the Society of Endoscopic and Laparoscopic Surgeons of Malaysia and was collaborated with representatives from the Ministry of Health Malaysia.

    Rice is the most important staple crop in Malaysia and is cultivated all over the country, including the state of Sabah. The uniqueness of rice cultivation in Sabah lies in the type of rice itself, deriving mainly from local or non-commercial cultivars but with distinctive characteristics including long grains, aromatic properties, and drought tolerance. However, despite having these important agricultural traits, information on the genetic diversity of Sabah rice remains limited. Hence, the purpose of this study was to determine the genetic polymorphisms of Sabah rice using random amplification of polymorphic DNA (RAPD) markers. A total of 101 alleles were profiled, from which 94% were identified as polymorphic. Phylogenetic analysis grouped the rice samples into three clusters, with two clusters classifying the ability of rice to grow under different planting conditions, suitable for growth irrigate and upland condition. The first cluster was dominated by cultivars that could survive in wet (irrigated) areas, while the other featured those that were found in dry (upland) areas. Furthermore, two alleles, OPA-05-B2 and OPA-01-B11, were found to be unique to cultivars within the upland cluster and were thus proposed to be involved in dry environmental adaptation. The results of the present study provide an insight into the genetic relationships and diversity of Sabah rice.

    Attention-deficit/hyperactivity disorder (ADHD), a common neurodevelopmental disorder, often persists into adulthood. In Malaysia, the prevalence rate of hyperactivity symptoms is highest among Chinese Malaysians. There are limited evidence-based treatment options targeting the core symptoms of ADHD, as well as executive functioning. In addition, conventional psychotherapeutic approaches for adults with ADHD have been found to be highly labor-intensive. The present study will evaluate the effectiveness of an online mindfulness-based intervention to reduce inattention and hyperactivity-impulsivity and improve executive functioning among Chinese Malaysian college emerging adults with ADHD. Informed by established literature, we will design an 8-week online mindfulness-based intervention (i.e., iMBI). We will conduct a two-arm randomized controlled trial comparing an iMBI plus treatment-as-usual group (n = 54) and an enhanced treatment-as-usual control group (n = 54). Outcome measures of inattention, hyperactivity-impulsivity, and executive functioning will be collected at baseline, immediately post-intervention, and 1-month post-intervention. The findings of the present study will not only demonstrate the implementation of iMBI as a new treatment modality but also inform practitioners on the effectiveness of iMBI in reducing the burden of adults living with ADHD.

    Fusarium genus comprises important saprophytic and phytopathogenic fungi and is widespread in nature. The present study reports the occurrence of Fusarium spp. in soils from two mangrove forests in northern Peninsular Malaysia and analyzed physico-chemical properties of the mangrove soil. Based on TEF-1α sequences, nine Fusarium species were identified: Fusarium solani species complex (FSSC) (n = 77), Fusarium verticillioides (n = 20), Fusarium incarnatum (n = 10), Fusarium proliferatum (n = 7), Fusarium lateritium (n = 4), Fusarium oxysporum (n = 3), Fusarium rigidiuscula (n = 2), Fusarium chlamydosporum (n = 1), and Fusarium camptoceras (n = 1); FSSC isolates were the most prevalent. Phylogenetic analysis of the combined TEF-1α and ITS sequences revealed diverse phylogenetic affinities among the FSSC isolates and potentially new phylogenetic clades of FSSC. Soil analysis showed varied carbon content, pH, soil moisture, and salinity, but not nitrogen content, between sampling locations. Regardless of the physico-chemical properties, various Fusarium species were recovered from the mangrove soils. These were likely saprophytes; however, some were well-known plant pathogens and opportunistic human pathogens. Thus, mangrove soils might serve as inoculum sources for plant and human pathogenic Fusarium species. The present study demonstrates the occurrence of various Fusarium species in the extreme environment of mangrove soil, thereby contributing to the knowledge on species diversity in Fusarium.

    The use of graphical knowledge representation formalisms with a representational vocabulary agreement of terms of conceptualization of the universe of discourse is a new high potential approach in the ontology engineering and knowledge management context. Initially, concept maps were used in the fields of education and learning. After that, it became popular in other areas due to its flexible and intuitive nature. It was also proven as a useful tool to improve communication in corporate environment. In the field of ontologies, concept maps were explored to be used to facilitate different aspects of ontology development. An essential reason behind this motivation is the structural resemblance of concept maps with the hierarchical structure of ontologies. This research aims to demonstrate quantitative evaluation of 4 different hypotheses related to the effectiveness of using concept maps for ontology conceptualization. The domain of Quran was selected for the purpose of this study and it was conducted in collaboration with the experts from the Centre of Quranic Research, Universiti Malaya, Kuala Lumpur, Malaysia. The results of the hypotheses demonstrated that concept mapping was easy to learn and implement for the majority of the participants. Most of them experienced improvement in domain knowledge regarding the vocabularies used to refer to the structure of organization of the Quran, namely Juz, Surah, Ayats, tafsir, Malay translation, English translation, and relationships among these entities. Therefore, concept maps instilled the element of learning through the conceptualization process and provided a platform for participants to resolve conflicting opinions and ambiguities of terms used immediately.

    Dengue fever (DF) is a global health problem and considered to be endemic in Malaysia. Conventional mosquito traps currently applied as vector control do not effectively reduce Aedes mosquito population. AedesTech Mosquito Home System (AMHS) is an autocidal ovitraps for Aedes mosquitoes that uses the ‘lure and kill’ concept and is expected to be able to reduce Aedes mosquito population. The effectiveness of AMHS in reducing Aedes mosquito population was investigated in Block A, B and D (control) of the 17th College, Universiti Putra Malaysia (UPM). For the first two weeks (pre-intervention), the conventional ovitraps were used to obtain the initial abundance of mosquito population in Block A, B and D. Subsequently, AMHS was used for the next three months and again followed by the conventional ovitrap for the final two weeks (post-intervention). Ovitrap Index, Hatching Index and percentage of emergence of adult mosquitoes were calculated once every two weeks. Data were analysed using Paired Sample T-test. Values were considered significant at p≤0.05. The Ovitrap Index that indicates the mosquito population at Block A and B was significantly higher (p≤0.05) than of Block D. Hatching Index of AMHS was significantly lower (p≤0.05) then conventional ovitraps. All mosquito eggs collected in AMHS did not develop into adult mosquitoes. There was a significant reduction (p≤0.05) in the mosquito population between the pre- and post-intervention. In conclusion, AMHS was effective in reducing the mosquito population in 17th College, UPM. Therefore, it is believed to be a very promising vector management option to control the incidence of DF.

    Background: Malaysia has been ranked the fattest country in Southeast Asia. Overweight and obesity are the fifth leading risk factor for death globally in 2008. It may lead to increase of risk of non-communicable diseases such as cardiovascular diseases, diabetes, cancer and hypertension.
    Objectives: This research aimed to determine the prevalence of overweight and association of overweight with sociodemography, lifestyle as well as its health related conditions of adults in Kampung Tiga Papan.
    Methods: Cross-sectional analytical study was used to achieve our specific objectives. A total of 199 adults aged 18 years and above in Kampung Tiga Papan had been recruited by non-probability sampling method. Sociodemographic data and lifestyle adopted were obtained via validated questionnaire, the BMI status of respondents were calculated, blood pressure was measured and DASS-21 score was used to assess mental health of the respondents.
    Results: There are 118 (59.3%) respondents categorized into overweight group (BMI>23 kg/m2) and 130 (65.3%) respondents are having abdominal obesity (Waist-hip ratio: male>0.9 and female>0.8). There are significant association between gender, household-income, alcohol status and preference of food and BMI status. Besides, there are significant association between gender, household income, alcohol and smoking status and significant increased risk of hypertension in overweight group.
    Conclusion: Overweight is associated to some sociodemographic and lifestyle factors. It helps to target high risk population and community intervention can be done to reduce the prevalence of overweight

    Introduction: Medication error is a global issue. Despite, the various impacts on health and non-health, continuous monitoring, assessment and intervention are required to reduce the number of medication error. Precise information on the root cause of medication error in Hospital Queen Elizabeth II, Kota Kinabalu will aid in the preventative measures to reduce medication error among nurses. Thus, this study aims to describe the incident of medication errors among nurses.
    Methods: A retrospective cross-sectional study was conducted to review medication error incidents Reports between 2015 to 2018. Data were analysed according to the type of error, day and shift of medication error occurred, causes and month of services. The collected data were analysed using descriptive statistics in SPSS 22.
    Results: A total of 54 reports was reviewed. The mean (SD) month of services among nurses involved in the medication error is 41.3 (24.9) months. The most common type of medication error is the wrong frequency with 23 (42.6%) cases. Majority cases of medication error occurred in weekdays with 41 (75.9%) cases and 24 (44.4%) cases happen during the night shift. Poor communication among healthcare workers was the most commonly reported human error with 42 (77.8%) reports, followed by36 (66.7%) reports of failure to comply standard of procedure in medication administration.
    Conclusion: Though this study found team factor is the recurrent causes, poorly designed work systems and individual factor should be imperious as well. A qualitative study is required to understand more on nurse behaviour practice towards medication administration. The high authority plays an important role to monitor this matter to improve medication safety practice.

    Past studies examining the direct relationship between private self-consciousness and online self-presentation behavior have not met with much success. The aim of this study was to examine the direct relationship between private self-consciousness and self-monitoring as well as the indirect relationship between these two variables through the mediation of locus of control and self-concept among Instagram users. Besides investigating locus of control and self-concept independently, serial mediation of locus of control and self-concept in the relationship between private self-consciousness and self-monitoring was also examined. A sample of 309 university students was conveniently drawn from three private universities in Kuala Lumpur, Malaysia. Participants completed a survey that collected data on private self-consciousness, internal locus of control, self-concept, self-monitoring on Instagram and relevant demographic data. Results of this study showed that there is no direct relationship between private self-consciousness and self-monitoring on Instagram. Independently, locus of control was found to mediate the relationship between private self-consciousness and self-monitoring while self-concept did not. The serial-multiple mediation test supported the mediating role of locus of control and self-concept on this relationship. These indirect relationships contribute to our understanding of the underlying mechanism through which private self-consciousness influences self-monitoring on Instagram.

    Adolescence is the developmental process of becoming an adult. This journey of physical and psychological maturation is filled with challenges and hormonal chaos, and teenagers experience unhappiness at times. From a psychological perspective, this study aimed to examine the association between motivation, self-esteem and happiness; and to explore the mediating role of motivation in the association between self-esteem and happiness among adolescents in Malaysia. 480 secondary school students were recruited using a multistage cluster sampling method and answered the Malay versions of the Subjective Happiness, Brief Motivation and Rosenberg Self-esteem scales. Both self-esteem and motivation were found positively correlated to happiness. The hypothetical mediating role of motivation on the association between self-esteem and happiness was also supported, indicating that individuals with higher self-esteem have higher motivation which may result in greater happiness. Since the direct association between self-esteem and happiness remained significant, a partial mediation of adolescents' motivation between self-esteem and happiness is indicated. The results showed that perceived self-esteem plays a role in predicting happiness and the presence of motivation enhances happiness, providing an insight to nurture happier adolescents for parents and educators in Malaysia.

    OBJECTIVE: Representing the largest proportion of healthcare workers, nurses play a significant role in oral health (OH) maintenance as part of a larger effort to promote holistic patient care. The study aims to determine nursing students' perceptions of OH education and practice in Malaysian and Australian nursing schools.

    MATERIALS AND METHODS: A self-administered questionnaire (content- and face-validated) survey was undertaken, classroom style, amongst final-year nursing students from selected Malaysian (n = 122, Response rate=97.6%) and Australian (n = 299, Response rate=54.7%) institutions. Quantitative data were analysed via Statistical Package for Social Science software (Chi-square and Fisher's exact tests, p ≤ 0.01).

    RESULTS: Significantly more Malaysian nursing students, compared to those in Australia, reported having encountered patients with OH issues (98.4% vs. 82.9%), namely halitosis (87.7% vs. 62.2%), oral ulcers (63.1% vs. 41.1%), oral/dental trauma (36.9% vs. 21.1%) and caries in children (28.7% vs. 7.7%). Less than half of Malaysian and Australian nursing students reported that they received adequate OH training (48.4% vs. 36.6%, p ≤ 0.01), especially in detecting oral cancer (18.0.0% vs. 22.6%, p ≤ 0.01) and preventing oral diseases (46.7% vs. 41.7%, p ≤ 0.01). Students in both countries demonstrated positive attitudes and believed in their role in OH care. Most students agreed that they should receive training in OH, especially in smoking cessation and providing OH care for patients with special needs. They also opined that a standardized evidence-based oral hygiene protocol is needed.

    CONCLUSION: Support for education and practice in this area of patient care suggested positive implications for further development of nurses' roles in OH promotion and management.

    Introduction: Parents play an essential role in their children’s tuberculosis (TB) treatment
    success despite many challenges from the beginning of their children’s symptoms until
    completion of the TB treatment. The challenges can be described as perceived barriers,
    according to the Health Belief Model, a theory of behaviour change. This study aims to explore
    parents’ experiences on the challenges in achieving a successful TB treatment for their child
    in two districts of Selangor state, Malaysia. Methods: The research was carried out using a
    phenomenology study design. In-depth interviews were conducted among purposively
    sampled parents of children with TB disease who have completed TB treatment or still
    undergoing treatment from MyTB version 2.1, a national TB surveillance database. The
    collected data was considered as achieving its saturation level if no new themes arise from
    the latest interviews’ session. The R-based Qualitative Data Analysis (RQDA) package
    version 0.2-8 was used for the thematic data analysis. Results: The total number of
    participants in this study was 15 mothers of children with TB disease; 12 (80%) of the children
    had completed TB treatment. There were six subthemes identified from this study focusing on
    the theme of multiple challenges, such as health symptoms challenges, TB investigation
    challenges, personal challenges, healthcare facilities challenges, administration medication
    challenges, and community challenges. Conclusions: Parents highlighted many challenges
    during the child’s illness phase, and they should be given adequate education and appropriate
    support to ensure TB treatment adherence. TB program managers should take action
    following the relevant parents’ feedback regarding the quality of TB care in a healthcare
    facility

    Watermelons (Citrullus lanatus) are known to have sufficient amino acid content. In this study, watermelons grown and consumed in Malaysia were investigated for their amino acid content, L-citrulline and L-arginine, by the isocratic RP-HPLC method. Flesh and rind watermelons were juiced, and freeze-dried samples were used for separation and quantification of L-citrulline and L-arginine. Three different mobile phases, 0.7% H3P04, 0.1% H3P04, and 0.7% H3P04 : ACN (90 : 10), were tested on two different columns using Zorbax Eclipse XDB-C18 and Gemini C18 with a flow rate of 0.5 mL/min and a detection wavelength at 195 nm. Efficient separation with reproducible resolution of L-citrulline and L-arginine was achieved using 0.1% H3P04 on the Gemini C18 column. The method was validated and good linearity of L-citrulline and L-arginine was obtained with R2 = 0.9956, y = 0.1664x + 2.4142 and R2 = 0.9912, y = 0.4100x + 3.4850, respectively. L-citrulline content showed the highest concentration in red watermelon of flesh and rind juice extract (43.81 mg/g and 45.02 mg/g), whereas L-arginine concentration was lower than L-citrulline, ranging from 3.39 to 11.14 mg/g. The isocratic RP-HPLC method with 0.1% H3P04 on the Gemini C18 column proved to be efficient for separation and quantification of L-citrulline and L-arginine in watermelons.

    PURPOSE: To assess the impact of extent and severity of chronic periodontitis (CP) on oral health-related quality of life (OHRQoL).

    MATERIALS AND METHODS: A cross-sectional comparative study was performed on subjects from multiple dental centres in Malaysia using a questionnaire covering sociodemographics, OHRQoL using the Malaysian Oral Health Impact Profile questionnaire, OHIP-14(M) and self-reported symptoms. Participants with severe CP were age-and gender-matched with periodontally healthy/mild periodontitis (HMP) participants based on inclusion and exclusion criteria. Full mouth periodontal examination was performed on participants. Outcome measures were OHIP-14(M) prevalence of impact and severity of impact scores.

    RESULTS: One hundred and thirty (130) participants comprising 65 severe CP and 65 HMP participants were included in the study. Prevalence of impact on OHRQoL was significantly higher in the severe CP than HMP group, with an odds ratio of 3. Mean OHIP-14(M) score was significantly higher in the severe CP (18.26 ± 10.22) compared to HMP (11.28± 8.09) group. The dimensions of psychological discomfort and functional limitation, and factors such as 'discomfort due to food stuck' and 'felt shy' were impacted more in severe CP compared to HMP group (p < 0.05). When compared with the HMP group, generalised severe CP participants showed higher prevalence of impact on OHRQoL [OR=5] (p < 0.05) compared to localised severe CP [OR=2] (p = 0.05). Participants who had experienced self-reported symptoms had statistically significant impacts on OHRQoL.

    CONCLUSIONS: Severe CP had a greater impact on OHRQoL compared to HMP. Impacts were mainly for functional limitation and psychological discomfort dimensions. When considering extent of disease, the impact on OHRQoL was mostly in generalised severe CP subgroup.

    The phoretic association between Macrocheles muscaedomesticae and flies that inhabited poultry manure in a poultry farm in Sungai Buloh, Selangor, Malaysia was studied. The effects of temperature, relative humidity and fly abundance on phoretic rates also were investigated. The most abundant fly species found was Musca domestica; Musca sorbens, Chrysomyia megacephala and Ophyra chalcogaster were present in relatively large numbers. Representatives of ten families of mites were found on collected Mu. domestica. The most common mite was Ma. muscaedomesticae (Macrochelidae), found on all four species of flies mentioned above. The highest infestation (2.0%) occurred on O. chalcogaster but Mu. domestica had the highest average number infested (5.7). The ventral part of the housefly's abdomen was the most common site of mite attachment. Usually only one mite was found attached per fly.
