    AIM(S): To determine the prevalence of medication administration errors and identify factors associated with medication administration errors among neonates in the neonatal intensive care units.

    DESIGN: Prospective direct observational study.

    METHODS: The study was conducted in the neonatal intensive care units of five public hospitals in Malaysia from April 2022 to March 2023. The preparation and administration of medications were observed using a standardized data collection form followed by chart review. After data collection, error identification was independently performed by two clinical pharmacists. Multivariable logistic regression was used to identify factors associated with medication administration errors.

    RESULTS: A total of 743 out of 1093 observed doses had at least one error, affecting 92.4% (157/170) neonates. The rate of medication administration errors was 68.0%. The top three most frequently occurring types of medication administration errors were wrong rate of administration (21.2%), wrong drug preparation (17.9%) and wrong dose (17.0%). Factors significantly associated with medication administration errors were medications administered intravenously, unavailability of a protocol, the number of prescribed medications, nursing experience, non-ventilated neonates and gestational age in weeks.

    CONCLUSION: Medication administration errors among neonates in the neonatal intensive care units are still common. The intravenous route of administration, absence of a protocol, younger gestational age, non-ventilated neonates, higher number of medications prescribed and increased years of nursing experience were significantly associated with medication administration errors.

    IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: The findings of this study will enable the implementation of effective and sustainable interventions to target the factors identified in reducing medication administration errors among neonates in the neonatal intensive care unit.

    REPORTING METHOD: We adhered to the STROBE checklist.

    PATIENT OR PUBLIC CONTRIBUTION: An expert panel consisting of healthcare professionals was involved in the identification of independent variables.

    A cross-sectional survey of 976 households in 41 villages covered by the Rural Health Improvement Scheme in Sarawak was carried out to determine the state of functioning and utilization of rural water supplies. The survey was carried out by inspection and interview. About one-third of the systems were functioning well, one-third imperfectly, and the remainder were no longer functioning. The coverage of households by water supply varied with the type of water supply, the overall coverage being 81.3%. Usage varied with the type of water supply and access, the overall figure being 87.1%, and the overall utilization was 70.8%. The study showed that it is important to account for water supply usage in impact evaluation because not all households have access and not all those with access use the water supply. It is also important to define water use, depending on whether the health outcome is a reduction in diseases that are water-borne or related to washing with water, because the percentage of households using the water for drinking is different from those using it for bathing.

    After two years' use of hexachlorocyclohexane (BHC) as a larvicide in Georgetown, on Penang Island, control of Culex fatigans breeding became unsatisfactory. Two laboratory colonies of fatigans were established, one from Georgetown, and one from Kuala Lumpur where no insecticides had been used; tests were then made to determine the median lethal concentrations (MLC) of BHC, dieldrin, and DDT for the larvae of the two strains. The Georgetown strain was found to have acquired a tenfold resistance to BHC, and also to dieldrin to which it had not been exposed, but it showed no significant increase of resistance to DDT, to which it had also not been exposed. A year later, when both strains had passed through some ten generations in the laboratory without exposure to insecticides, the Georgetown strain was found to have lost much of its resistance to BHC, although the MLC was still twice that of the non-resistant Kuala Lumpur strain.

    Colonies of three strains of Aëdes aegypti resistant to DDT were obtained from Trinidad, Haiti and Malaya and reared beside a normal colony. From their relative resistance to a series of compounds analogous to DDT, characteristic resistance "spectra" were obtained. The two colonies from the West Indies showed a similar type of resistance, rather different from the (smaller) resistance of the Malay strain. No resistance to methoxychlor or dieldrin was found.

    Population blooms of scyphozoan jellyfish in tropical shallow water regions can fuel localized fisheries but also negatively impact human welfare. However, there is a lack of baseline ecological data regarding the scyphozoans in the region, which could be used to manage a fast-growing fishery and mitigate potential impacts. Thus, this study aims to investigate the temporal factors driving the distribution of scyphozoan community along the environmental gradients under different monsoon seasons, rainfall periods, moon phases, and diel-tidal conditions in the Klang Strait located in the central region along the west coast of Peninsular Malaysia, where bloom events are increasing. Scyphozoan samples were collected using commercial bag nets during a 19-month survey. Temporal variations in species abundance and composition were evident and related to the local environmental parameters (salinity, dissolved oxygen, temperature, turbidity, and pH) that varied with the regional monsoon events, although these effects appeared to be species-specific. Phyllorhiza punctata, Acromitus flagellatus, Lychnorhiza malayensis, and Rhopilema esculentum were more abundant during the wetter northeast monsoon (NEM) while the abundance of Chrysaora chinensis and Lobonemoides robustus increased during the drier southwest monsoon (SWM). During the wet period of NEM, scyphozoan abundance was generally higher during the daytime than night-time. The regional monsoon regime and local hydrological events account for jellyfish abundance in the nearshore area with concurrent threats to coastal tourism and power plants, as well as benefits to fisheries especially during the NEM.

    INTRODUCTION: The modern healthcare landscape with the emergence of video recording, has found applications in research, training, audit, quality improvement, and safety surveillance. Notably, advancements in camera technology have led to the development of smaller, lighter devices, enabling discreet usage and enhancing usability in clinical settings. Its adoption represents more than technological advancement; it entails a complex balance between improving patient care and respecting individual rights. Ethical considerations surrounding patient privacy, ownership of recordings, patient autonomy and healthcare provider responsibilities have garnered significant attention. In Malaysia, the adoption of video recordings in clinical interactions and consultations has been accepted in research, training and several medical fields. However, recording patients during clinical practice can be challenging, as there are scarce ethical guidelines for its practice. This review aims to gather and categorise the ethical challenges associated with recording videos of patients in healthcare facilities globally and identify research gaps specific to Malaysian healthcare settings. By addressing the ethical challenges globally, we can ensure the responsible and ethical use of video recording technology to enhance patient care while respecting individual rights.

    MATERIALS AND METHODS: Articles from Scopus, Web of Science and PubMed databases were collected following PRISMA guidelines. Key term searches included "video recording," "ethical issues," and "patients." Inclusion criteria encompassed video and audio recording interactions between healthcare providers and patients in any clinical setting, final publications, and the English language. Exclusions were imaging or photography recording and non-clinical settings. The qualitative synthesis involved iterative reading, thematic coding analysis in Excel, and specific analysis to address the research question.

    RESULTS: Initial database search, identified 363 records. After screening, a total of 22 articles were included for analysis. Five themes were identified from the selected articles: i) privacy and confidentiality, ii) informed consent, iii) beneficence and non-maleficence, iv) integrity and professionalism and v) governance, policy and legal framework. Majority of the reviewed articles concentrate on backgrounds within the fields of psychiatry, neurology and surgical-based medical specialities. The identified themes have demonstrated consistency across the majority of the articles analysed. Among the most frequently discussed themes, it's evident that ethical concerns extend beyond just the patient's realm to encompass the responsibilities of the healthcare provider (HCP) as well. Both patients and HCPs have their respective rights and responsibilities in ensuring the ethical use of video recording in clinical settings.

    CONCLUSION: In conclusion, this review has highlighted the multifaceted ethical challenges surrounding the integration of video recording in healthcare settings. While video recording offers benefits for patient care, education, and quality improvement, its adoption presents complexities. Ethical dilemmas concerning patient privacy, consent, and data management must be addressed alongside practical barriers like technological limitations and resource constraints. Collaboration among healthcare providers, policymakers, and stakeholders is crucial to navigating these challenges ethically. Future research should delve into patient perspectives, develop ethical guidelines, and assess the impact of video recording on patient outcomes. By understanding these implications, healthcare can effectively leverage video recording to improve patient care while maintaining ethical standards.

    BACKGROUND: Like other countries, surface water degradation in Malaysia is linked with common global issues. Although different aspects of drinking water suitability have been examined, the overall understanding of drinking water quality in Malaysia is poor.

    OBJECTIVE: Hence, the present review aims to provide an understanding of drinking water (tap water, groundwater, gravity feed system) quality and its potential implications on policy, human health, and drinking water management law and identification of potential direction of future drinking water research and management needs in Malaysia.

    METHODS: This study utilized a scoping review method. PRISMA Extension for Scoping Reviews was used for search strategy. Relevant studies were screened using the selected keywords and databases.

    RESULTS: A total of 26 drinking water quality studies involving tap water, groundwater, and gravity feed systems have been selected for review. These studies found that the majority of Malaysian Drinking Water and WHO Drinking Water standards have been met. High levels of Cu, Cd, Fe and Pb were attributable to galvanized plumbing and pipe material corrosion. Variation of fluoride in tap water depends on dosage planning and operational processes of the public water supply. Pollutants (nitrate and ammonia) in groundwater and gravity feed system water have been linked to agricultural practices in rural areas. Microbiological quality in tap water is associated with growing biofilms inside the pipelines while in groundwater is caused by shallow surface events. However, only eight studies have reported about the human risks of chemical pollutants in tap water.

    IMPACT STATEMENT: The review discusses the state of drinking water quality in Malaysia and its impact on public health. It suggests that policymakers can use this information to improve the quality of drinking water and enforce restrictions, while also raising public awareness about the importance of safe drinking water. The study can guide future research and initiatives in Malaysia, ultimately contributing to efforts to ensure access to clean and dependable drinking water.

    It has been shown that lipid peroxidation product levels in the soleus muscles of rats fed palm olein were lower than in the soleus muscles of rats fed soya bean oil. A study was carried out to test our hypothesis that the lower level of lipid peroxidation products in the soleus muscle of palm olein-fed rats is due, at least partly, to the higher amount of vitamin E in their soleus muscles. Experimentally induced hyperthyroid rats were fed either ground rat chow or ground rat chow mixed with palm olein oil or soya bean oil for a period of 8 weeks. Euthyroid rats fed ground rat chow for a similar period served as controls. At the end of the 8-week period, the rats were sacrificed and the α-tocopherol and tocotrienol levels in their soleus muscles were measured using high pressure liquid chromatography. It was found that the levels of α-tocopherol (23.682 ± 0.363), α-tocotrienol (1.974 ± 0.040) and γ-tocotrienol (1.418 ± 0.054) in μg/g tissue wet weight in the soleus muscles of hyperthyroid rats fed palm olein oil were statistically significantly higher than those found in the soleus muscles of hyperthyroid rats fed soya bean oil, which were 14.299 ± 0.378, 0.053 ± 0.053 and 0.184 ± 0.120μg/g tissue wet weight, respectively. The result shows that the increased level of a-tocopherol and tocotrienols found in the soleus muscles of hyperthyroid rats fed palm olein oil is responsible, at least partly, for the lower amount of lipid peroxidation products in these muscles compared with the soleus muscles of hyperthyroid rats fed soya bean oil in our earlier study.

    This scoping review aims to provide a comprehensive overview of human melioidosis in Southeast Asia as well as to highlight knowledge gaps in the prevalence and risk factors of this life-threatening disease using available evidence-based data for better diagnosis and treatment. Preferred Reporting Items for Systematic Review and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) was used as the guideline for this review. The literature search was conducted on 23 March 2022 through two electronic databases (PubMed and Scopus) using lists of keywords referring to the Medical Subject Headings (MeSH) thesaurus. A total of 38 articles related to human melioidosis were included from 645 screened articles. These studies were carried out between 1986 and 2019 in six Southeast Asian countries: Thailand, Cambodia, Malaysia, Myanmar, Singapore, and Vietnam. Melioidosis has been reported with a high disease prevalence among high-risk populations. Studies in Thailand (48.0%) and Cambodia (74.4%) revealed disease prevalence in patients with septic arthritis and children with suppurative parotitis, respectively. Other studies in Thailand (63.5%) and Malaysia (54.4% and 65.7%) showed a high seroprevalence of melioidosis among Tsunami survivors and military personnel, respectively. Additionally, this review documented soil and water exposure, diabetes mellitus, chronic renal failure, thalassemia, and children under the age of 15 as the main risk factors for melioidosis. Human melioidosis is currently under-reported in Southeast Asia and its true prevalence is unknown.

    BACKGROUND: Asia consists of diverse nations with extremely variable health care systems. Integrated real-world data (RWD) research warehouses provide vast interconnected data sets that uphold statistical rigor. Yet, their intricate details remain underexplored, restricting their broader applications.

    OBJECTIVE: Building on our previous research that analyzed integrated RWD warehouses in India, Thailand, and Taiwan, this study extends the research to 7 distinct health care systems: Hong Kong, Indonesia, Malaysia, Pakistan, the Philippines, Singapore, and Vietnam. We aimed to map the evolving landscape of RWD, preferences for methodologies, and database use and archetype the health systems based on existing intrinsic capability for RWD generation.

    METHODS: A systematic scoping review methodology was used, centering on contemporary English literature on PubMed (search date: May 9, 2023). Rigorous screening as defined by eligibility criteria identified RWD studies from multiple health care facilities in at least 1 of the 7 target Asian nations. Point estimates and their associated errors were determined for the data collected from eligible studies.

    RESULTS: Of the 1483 real-world evidence citations identified on May 9, 2023, a total of 369 (24.9%) fulfilled the requirements for data extraction and subsequent analysis. Singapore, Hong Kong, and Malaysia contributed to ≥100 publications, with each country marked by a higher proportion of single-country studies at 51% (80/157), 66.2% (86/130), and 50% (50/100), respectively, and were classified as solo scholars. Indonesia, Pakistan, Vietnam, and the Philippines had fewer publications and a higher proportion of cross-country collaboration studies (CCCSs) at 79% (26/33), 58% (18/31), 74% (20/27), and 86% (19/22), respectively, and were classified as global collaborators. Collaboration with countries outside the 7 target nations appeared in 84.2% to 97.7% of the CCCSs of each nation. Among target nations, Singapore and Malaysia emerged as preferred research partners for other nations. From 2018 to 2023, most nations showed an increasing trend in study numbers, with Vietnam (24.5%) and Pakistan (21.2%) leading the growth; the only exception was the Philippines, which declined by -14.5%. Clinical registry databases were predominant across all CCCSs from every target nation. For single-country studies, Indonesia, Malaysia, and the Philippines favored clinical registries; Singapore had a balanced use of clinical registries and electronic medical or health records, whereas Hong Kong, Pakistan, and Vietnam leaned toward electronic medical or health records. Overall, 89.9% (310/345) of the studies took >2 years from completion to publication.

    CONCLUSIONS: The observed variations in contemporary RWD publications across the 7 nations in Asia exemplify distinct research landscapes across nations that are partially explained by their diverse economic, clinical, and research settings. Nevertheless, recognizing these variations is pivotal for fostering tailored, synergistic strategies that amplify RWD's potential in guiding future health care research and policy decisions.

    OBJECTIVE: This is a scoping review of Malaysian scientific studies on medication adherence among persons with type 2 diabetes mellitus (T2DM).

    METHODOLOGY: We conducted a bibliographic search of PubMed, Scopus and Google Scholar using the following keywords: "medication adherence," "drug compliance," "DMTAC" and "Malaysia." The search covered all publications up to 31 December 2021. Eligible articles were original studies conducted in Malaysia that measured or quantified medication adherence among persons with T2DM.

    RESULTS: We identified 64 eligible studies published between 2008 to 2021. Most studies included patients with T2DM in ambulatory facilities. Five studies were qualitative research. The quantitative research publications included clinical trials, and cross-sectional, validation, retrospective and prospective cohort studies. Thirty-eight studies used medication adherence scales. The Morisky Medication Adherence Scale (MMAS-8, used in 20 studies) and Malaysian Medication Adherence Scale (MALMAS, used in 6 studies) were the most commonly used tools. There were 6 validation studies with 4 medication adherence scales. A meta-analysis of 10 studies using MMAS-8 or MALMAS revealed that the pooled prevalence of low medication adherence is 34.2% (95% CI: 27.4 to 41.2, random effects model). Eighteen publications evaluated various aspects of the Diabetes Medication Therapy Adherence Clinics (DMTAC).

    CONCLUSION: This scoping review documented extensive research on medication adherence among persons with diabetes in Malaysia. The quantitative meta-analysis showed a pooled low medication adherence rate.

    The effect of open-pit bauxite mining on beach sediment contamination in the urban coastal environment of Kuantan City, Malaysia, was investigated. The contents of 11 heavy metals (Pb, Cd, Al, Mn, Cu, Zn, Fe, As, Ni, Cr, and Ag) in 30 samples from Kuantan beach sediment zones (supratidal, intertidal, and subtidal) were determined using inductively coupled plasma optical emission spectrometry followed by contamination indexes, Pearson's correlation analysis, and principal component analysis (PCA). The results indicated that Cd, As, Ni, and Ag values in beach sediment zones were significantly higher compared to background values. Contamination indexes suggest that Cd, As, Ni, and Ag were highly contaminated, and moderate to extremely enriched near the Kuantan Port. However, these heavy metal concentrations are lower compared to previous studies in the region. Sediment quality guidelines highlighted the occasional presence of Cd and Ag. Based on Pearson's correlation analysis, PCA, and cluster analysis, sources of these heavy metals in beach sediments were likely from agricultural runoff, uncontrolled industrial and residential discharge, and unprotected mine waste near the Kuantan Port. Furthermore, effective management of mining practices and ongoing monitoring are essential to reduce contamination risks.

    Wastewater treatment plant (WWTP) is a sustainable technique for making wastewater reusable for non-potable purposes. However, in developing countries, most conventional WWTPs are not equipped to trap all pharmaceutical residues (PRs) and pharmaceutically active chemicals (PhACs). This study aims to perform non-target screening of these contaminants in wastewater and explore health and environmental hazards and the removal efficiency of a WWTP in Malaysia. At Indah Water WWTP, a total of 28 wastewater samples (i.e., 2 L each of 14 influent and 14 effluent) were collected every day for a week from February to April 2023. The supernatant of the centrifuged sample was analyzed with the LCMS-QTOF system. Chromatographic profiles were analyzed, and the compounds were annotated using the METLIN database. Categorical data were statistically analyzed with SPSS 29.0 using a chi-square test and continuous variables using paired t-test and multiple regression. PRs like micronutrient (9, 2.3%) and PhACs like lipid (83, 20.8%) were more frequent. Detection frequencies of PRs and PhACs were 72 (18%) and 328 (82%), respectively. Efficiency of WWTP was 36.4 to 100% for PRs removal (mean ± SD: 65.85 ± 56.43%) and 20 to 100% for PhACs removal (mean ± SD: 49.30 ± 55.94%). A total of 943 (mean ± SD: 67.36 ± 43.28) and 400 (mean ± SD: 28.57 ± 32.44) unique PRs and PhACs were recorded. A total of 40 (10%) PRs and PhACs had the potential to irritate eyes, skin, and respiratory tract, and 46 (11.5%) chemicals needed to be avoided from being discharged into the environment. Though WWTP was 98.0% compliant with environmental standards, its efficiency should still be increased to remove the full range of PRs and PhACs. The research has implications for SDGs 6 and 14.

    This study investigates the effectiveness and efficiency of two topological data analysis (TDA) techniques, the conventional Mapper (CM) and its variant version, the Ball Mapper (BM), in analyzing the behavior of six major air pollutants (NO2, PM10, PM2.5, O3, CO, and SO2) across 60 air quality monitoring stations in Malaysia. Topological graphs produced by CM and BM reveal redundant monitoring stations and geographical relationships corresponding to air pollutant behavior, providing better visualization than traditional hierarchical clustering. Additionally, a comparative analysis of topological graph structures was conducted using node degree distribution, topological graph indices, and Dynamic Time Warping (DTW) to evaluate the sensitivity and performance of these TDA techniques. Both approaches yielded valuable insights in representing the air quality monitoring stations network; however, the complexity of CM, which requires multiple parameters, poses a challenge in graph construction. In contrast, the simplicity of BM, requiring only a single parameter, is preferable for representing air pollutant behavior. The findings suggest an alternative approach for assessing and identifying redundancies in air quality monitoring stations, which could contribute to improved air quality monitoring management and more effective regulatory policies.

    Coral reefs house a great variety of symbiotic associations, including parasitism. One of the crucial issues in the host-symbiont interactions is the parasites' feeding mode. Does the parasite/symbiont use the host's tissues for nutrition, steal food from the host's digestive system, or take food directly from the environment? However, most of the parasitism in corals is endosymbiotic (endoparasitic). Their trophic interactions are difficult to identify since they only occur in intact associations. This work uses stable isotope analysis (SIA) of carbon and nitrogen and morphological analysis to study the trophic relationship between the crustacean endoparasites, the Ascothoracida (genera Baccalaureus, Sessilogoga, and Zibrowia) and their various coral hosts ranging from Zoantharia (Palythoa) to Antipatharia (Antipathes), and Scleractinia (Dendrophyllia). The hosts belong to different coral taxa and obtain food from different sources, reflected in their stable isotope values. The SIA, supported by the morphological analysis, suggests that the Zibrowia parasite feeds directly on its Dendrophyllia host. Sessilogoga retains vagility within and around the black coral colony. It has typical generalized piercing mouth parts with numerous teeth and denticles. Sessilogoga may use antipatharian tissues for food directly as well as sucks food fluids from the host's gastrovascular system. There is no clear trophic shift trend between Palythoa and its parasite Baccalaureus. Such differences exclude the possibility of the parasite feeding predominantly on its host's tissues and suggest a broad spectrum of food sources. Thus, SIA reveals that endosymbiotic ascothoracidans may not always be true parasitic but also opportunistic feeders, which steal food directly from the host gastric cavity.

    OBJECTIVES: Leprosy remains a public health concern in Malaysia and globally. We aim to review the characteristics of leprosy patients in a tertiary institution in urban Malaysia.
    DESIGN: This is a case series of 27 leprosy patients who presented between 2008 and 2013.
    RESULTS: The majority of our patients consisted of male (74.1%), Malaysian (63.0%), blue collar workers (51.9%) and married (59.3%) patients; 48.1% had lepromatous leprosy. All except one of the patients presented with skin lesions, 25.9% had nerve involvement and 33.3% developed lepra reactions. Forty-four point four percent (44.4%) of the cases seen initially in the primary care setup were misdiagnosed.
    CONCLUSIONS: Doctors need to have a high index of suspicion for leprosy when patients present with suggestive skin, nerve or musculoskeletal lesions. Immigrants accounted for 37% of cases and these patients may become a reservoir of infection, thus accounting for the rise in incidence. An increasing trend in multibacillary cases may be attributed to the spread from migrants from countries with a high burden of leprosy.
