    Delamination factor in drilling represents the maximum spread of imperfections around the drilled hole in a polymer composite. Df can directly affect the performance of the drilled component. This study focuses on investigating the influence of nanofillers, titanium dioxide and graphene, with epoxy in varying quantities ranging from 1 to 4 wt%, on the delamination behavior of the glass fiber-reinforced composites. The parameters, such as spindle speeds (600, 1200, and 1800 rpm), feed rates (30, 40, and 50 mm/min), and drill bit diameter (4, 6, and 8 mm), were considered. A high-resolution camera was used to capture the images of the drilled hole, which were processed using MATLAB to compute the delamination factor at top and rear faces of the composite. Additionally, thrust force obtained from the dynamometer at various nanofiller quantities was analyzed. The thrust force decreased with an increase in the spindle speed and the feed rate. Spindle speed and feed rate contributed the least to delamination, while filler percentage contributed the least to thrust. The mean GRG showed that GT1, a drill bit diameter of 4 mm, a spindle speed of 1800 rpm and a feed rate of 50 mm/min were the optimum parameters.

    BACKGROUND: The World Health Organization (WHO) has recommended the development of a cleft-specific database for collecting and analyzing data on patients with cleft from birth to adulthood. However, such a database currently does not exist in Malaysia. The objective of this study was to develop a cleft lip and/or palate (CL/P) database software for Malaysia to streamline data collection and support comprehensive research to enhance outcomes of care.

    METHODS: The development of the database software involves several key stages, including determining the requirements, designing the software interface, implementing the system, conducting thorough testing, and completing comprehensive documentation. The database software was mainly developed internally within the research institution. The team involved in developing the clinical database includes cleft clinicians, software developers, software designers, members of the Cleft Lip and Palate Association Malaysia (CLAPAM), and experts in database development.

    RESULTS: An online and offline database software has been developed to store information on patients with CL/P in Malaysia. It is designed to be user-friendly, accommodating multiple specialties and capable of storing photographs, radiology, and three-dimensional files. Various methods have been implemented to ensure data security. Additionally, documentation including video tutorials, consent forms, and hard copy versions has been developed to complement the database.

    CONCLUSION: A specialized cleft-specific database software has been successfully developed for use in Malaysia to improve data management and support CL/P patient care.

    INTRODUCTION: Data on the impact of World Health Organization (WHO)'s guideline changes and COVID-19 on ART initiation in the Asia-Pacific remain scarce. This study described temporal trends from HIV diagnosis to ART initiation from 2013 to 2023 and its associated factors.

    METHODS: Adults (≥ 18 years) diagnosed with HIV after 2013 in a regional observational cohort were included. Fine and Gray competing risk regression examined predictors of ART initiation (≥ 3 antiretroviral medications), accounting for those lost to follow-up or deceased before treatment considered as competing risks.

    RESULTS: Among 14,968 participants, most were male (70.1%), with a median age of 36 years (interquartile range [IQR]: 28-44). At HIV diagnosis, median CD4 count was 208 cells/µL (IQR: 69-395), and median viral load was 86,296 copies/mL (IQR: 13,186-392,000). Over 85% of participants had initiated ART during the study period. Median time from HIV diagnosis to ART initiation differed across years of HIV diagnosis: 51 days (2013-2015), 28 days (2016-2019), and 26 days (≥ 2020). Factors associated with shorter time to ART initiation were higher country income-level (upper-middle: sub-distribution hazard ratio [SHR] = 1.34, 95% CI: 1.28, 1.40; high: SHR = 1.35, 95% CI: 1.28, 1.43; vs. lower-middle); HIV transmission via male-to-male contact (SHR = 1.06, 95% CI: 1.02, 1.11) or injection drug use (SHR = 1.23, 95% CI: 1.09, 1.38; vs. heterosexual contact); and later years of HIV diagnosis (2016-2019: SHR = 1.33, 95% CI: 1.28, 1.38; ≥ 2020: SHR = 1.40, 95% CI: 1.33, 1.48; vs. 2013-2015). Those with higher CD4 counts had longer time to ART start (350-499 cells/µL: SHR = 0.76, 95% CI: 0.67, 0.86; > 500 cells/µL: SHR = 0.55, 95% CI: 0.49, 0.61; vs. CD4

    OBJECTIVE: This study aimed to evaluate the reliability and validity of the Binge Eating Disorder Screener-7 (BEDS-7) across 42 countries and 26 languages, assessing its reliability and validity as a screening tool for binge-eating disorder (BED) in diverse cultural contexts. Specifically, it sought to enhance early recognition of BED symptoms in primary care settings globally, contributing to a standardized framework for assessing BED.

    METHOD: The International Sex Survey, a cross-sectional online study, was conducted in 42 countries and 26 languages. A diverse community sample of 82,243 participants, aged 18 years or older, completed the BEDS-7 and measures of sexuality, mental health, substance use, and sociodemographic characteristics. Confirmatory factor analyses and tests of measurement invariance were employed to evaluate the reliability and validity of the BEDS-7 across languages, countries, genders, and sexual orientations.

    RESULTS: The BEDS-7 demonstrated scalar factorial invariance across languages and countries, indicating consistent factor loadings and item intercepts. In contrast, the screener showed residual invariance across gender and sexual orientation groups, supporting its robustness across these demographics. Kruskal-Wallis tests revealed significant differences in BED symptoms across languages, countries, genders, and sexual orientations, with the highest BED scores observed among queer, pansexual, and gender-diverse individuals. The BEDS-7 also demonstrated adequate reliability (Cronbach's alpha > 0.80) and moderate criterion validity.

    DISCUSSION: The findings provide further evidence of the reliability and validity of the BEDS-7 as a potential screening tool for identifying probable cases of BED globally, facilitating early intervention in primary care settings.

    One significant challenge in stormwater management is the limited involvement of stakeholders in decision-making. As urban areas face increasing storm-related challenges, it is crucial to integrate nature-based solutions and stakeholder participation to enhance stormwater resilience. This study evaluated five solutions-green roof, grass swale, vegetation buffer zone, rain garden, and sunken green space - to determine their strategic positioning using the Internal-External matrix. An online questionnaire survey was conducted to gather expert input, ensuring a structured and judgment-based assessment. The study was performed at Merdeka Square, Kuala Lumpur, Malaysia, a heritage site with unique urban constraints. Results identified grass swale and rain garden as the most effective solutions, achieving the optimal strategic position in the IE matrix, making them the preferred options for future stormwater management strategies. These findings provide a replicable framework for integrating nature-based solutions in urban planning while balancing environmental, regulatory, and stakeholder considerations.

    The escalating threat of infectious diseases, exacerbated by antimicrobial resistance (AMR) and biofilm formation, necessitates innovative therapeutic strategies. This review presents a comprehensive exploration of the potential of nanoparticles synthesized from natural sources, including plant extracts, microbial products, and marine compounds, as antimicrobial agents. These naturally derived nanoparticles demonstrated significant antibiofilm and antivirulence effects, with specific examples revealing their capacity to reduce biofilm mass by up to 78% and inhibit bacterial quorum sensing by 65%. The integration of bioactive compounds, such as polyphenols and chitosan, facilitates nanoparticle stability and enhances antimicrobial efficacy, while green synthesis protocols reduce environmental risks. Notably, the review identifies the potential of silver nanoparticles synthesized using green tea extracts, achieving 85% inhibition of polymicrobial growth in vitro. Despite these promising results, challenges such as standardization of synthesis protocols and scalability persist. This study underscores the transformative potential of leveraging naturally sourced nanoparticles as sustainable alternatives to conventional antimicrobials, offering quantitative insights for their future application in combating mono- and polymicrobial infections.

    BACKGROUND AND AIM: The extracted phycocyanin by-products retain nutritional value, including proteins, polysaccharides, and bioactive compounds, which have the potential as feed supplements in broiler production. This study aimed to evaluate the effect of by-products acquired during phycocyanin extraction, which is used as a novel synbiotic supplement, on the production performance and intestinal health of broilers in a tropical climate.

    MATERIALS AND METHODS: A total of 240 one-day-old male Ross 308 broilers were randomly distributed among five dietary treatment groups; they received a diet supplemented with a synbiotic product (probiotic [Lactobacillus johnsonii] at least 1.0 × 108 colony-forming unit/mg with prebiotic [by-product of phycocyanin extraction]) at 0.000%, 0.025%, 0.050%, 0.075%, and 0.100%. We investigated the effects of dietary synbiotic supplements on the growth performance, meat quality, intestinal morphology, and cecal bacterial population of broiler chickens aged 35 days.

    RESULTS: Synbiotics used as a dietary supplement did not affect the growth performance of broilers during any experimental period (p > 0.05); however, it significantly increased the redness of meat and decreased the levels of thiobarbituric acid-reactive substances on days 3 and 7 of storage (p < 0.05). Moreover, synbiotics significantly improved the height and surface area of villi in the duodenum and jejunum (p < 0.05).

    CONCLUSION: The study demonstrated that dietary supplementation with 0.1% synbiotics, incorporating a by-product of phycocyanin extraction, did not significantly influence the growth performance of broiler chickens. However, it positively affected meat quality by increasing redness and reducing lipid oxidation during storage. Additionally, synbiotic supplementation significantly enhanced intestinal health by improving the villi height and surface area in the duodenum and jejunum, highlighting its potential benefits for broiler intestinal morphology and meat quality in tropical climates. Further research is recommended to explore the mechanisms underlying these effects and their implications for long-term poultry health and productivity.

    BACKGROUND AND AIM: Acanthamoeba spp. are pathogenic microorganisms linked to severe infections in humans and animals, requiring a deeper understanding of their encystation process for effective diagnostics and research. This study focused on developing a novel encystment medium to induce synchronized encystation of Acanthamoeba spp. efficiently and rapidly.

    MATERIALS AND METHODS: The study employed response surface methodology with a central composite design to optimize the encystment medium formulation. The key components included Tris-HCl, NaCl, glucose, and MgCl2. The optimized liquid medium was spray-dried to produce a dehydrated powder for practical application. The encystation efficiency of different Acanthamoeba strains was assessed using hemocytometry and fluorescence microscopy.

    RESULTS: The optimized medium, comprising 3.152 g/L Tris-HCl, 5.55 g/L NaCl, 8% (w/v) glucose, and 5.0 mM MgCl2 at pH 9.0, demonstrated exceptional encystation efficiency with rates ranging from 99% to 100%. A spray-dried powdered version of this medium was equally effective, achieving a 98.77% encystation rate for A. castellanii American Type Culture Collection 50739 in glucose-free conditions. Notably, optimal glucose concentrations varied among Acanthamoeba strains, with certain strains reaching maximum encystation at 6-8% glucose.

    CONCLUSION: This study successfully developed an innovative encystment medium that promotes rapid and efficient cyst production in Acanthamoeba spp. The medium enhances laboratory research and diagnostic capabilities, paving the way for future advancements in understanding and managing Acanthamoeba infections.

    BACKGROUND AND AIM: Exercise-induced oxidative stress and inflammation adversely affect the health and performance of athletic horses. This study aimed to evaluate the safety of edible bird's nest (EBN) supplementation and its potential anti-inflammatory and immunomodulatory effects in Arabian race stallions during exercise. Key objectives included assessing EBN's impact on hepatic and renal function, hematological profiles, and sialic acid (SA) levels.

    MATERIALS AND METHODS: Two experiments were conducted on 18 Arabian stallions. In Experiment 1, six healthy stallions were divided into control (n = 2) and EBN-supplemented groups (n = 4) to assess safety. The treatment group received 10 g of EBN daily for 12 days. Vital signs, hematological parameters, and organ function markers were monitored. In Experiment 2, 12 stallions were divided into three groups: EBN (n = 3), Premier E® (n = 3), and control (n = 6). The exercise regimen included a daily 10-min walk, 10-min canter (30 km/h), and 10-min walk for 30 days. Blood samples were analyzed for hematological indices and SA levels pre- and post-exercise.

    RESULTS: In Experiment 1, EBN supplementation demonstrated no adverse effects, maintaining normal hematological and vital parameters. Kidney and liver function tests revealed significantly reduced creatine kinase, total bilirubin, and aspartate aminotransferase levels in the EBN group. Experiment 2 showed higher SA levels post-exercise in the EBN group (p < 0.05) compared to Premier E® and control groups, suggesting enhanced anti-inflammatory response. Hematological indices, including mean corpuscular volume, red cell distribution width, and platelet counts, were significantly improved in the EBN group, indicating potential immunomodulatory benefits.

    CONCLUSION: EBN supplementation is safe and offers anti-inflammatory and immunomodulatory effects in Arabian race stallions, reducing exercise-induced hepatic and muscular stress markers while enhancing recovery. These findings support EBN as a valuable dietary supplement for performance horses. Further studies should explore long-term effects and molecular mechanisms to optimize its use in equine sports.

    Atypical optic neuritis and posterior scleritis can indicate extrapulmonary tuberculosis (TB) caused by Mycobacterium tuberculosis. We present a rare case of bilateral atypical optic neuritis accompanied by posterior scleritis secondary to TB. A 36-year-old gentleman presented with a four-day history of blurred vision in both eyes, along with pain during eye movements. His medical history included intermittent low-grade fever and a persistent cough lasting four months, accompanied by significant weight loss of 13 kg over two months. On examination, visual acuity in the right eye was 6/36, while perception of light (PL) was present in the left eye. A positive relative afferent pupillary defect was noted in the left eye, with reduced light brightness and red desaturation observed. Both anterior segments appeared normal. Fundoscopic examination revealed bilateral hyperemic swollen optic discs. Chest radiography showed opacities in the right upper and middle lung fields. MRI of the orbit and brain demonstrated enhancement of the optic nerves in both eyes, along with pronounced posterior scleritis. Sputum analysis for acid-fast bacilli suggested pulmonary involvement. Lumbar puncture results were unremarkable, with normal opening pressure and cytology. The patient was diagnosed with bilateral atypical optic neuritis and posterior scleritis secondary to pulmonary TB. He was promptly started on an antitubercular regimen. Systemic high-dose methylprednisolone was introduced five days later. However, his condition deteriorated to PL in both eyes with pale discs after two weeks. Despite a modified corticosteroid regimen, vision remained poor upon discharge. Atypical optic neuritis may overlap with posterior scleritis and cause severe, sight-threatening conditions. Early diagnosis and comprehensive management of TB are critical for improving outcomes and preventing long-term damage.

    BACKGROUND AND AIMS: This retrospective cohort study aimed to determine the utilization rate of statin therapy for primary prevention of cardiovascular disease (CVD) and factors associated with its use in patients prior to experiencing their first ST-elevation myocardial infarction (STEMI).

    METHODS: The study included 177 patients admitted for their first episode of STEMI at a Malaysian secondary hospital in 2020. Data were retrospectively collected from the electronic health information system. Logistic regression analysis was performed to identify significant predictors of statin therapy utilization for primary prevention.

    RESULTS: Of the 177 patients, only 15.8% (n = 28) had been prescribed statin therapy for the primary prevention of CVD prior to their first STEMI. Hypertension and dyslipidemia were identified as significant predictors of statin use, with adjusted odds ratios (AOR) of 9.570 (95% CI: 1.859-49.281) and 37.900 (95% CI: 6.716-213.87), respectively. Follow-up data indicated significantly reduced cholesterol levels post-STEMI, demonstrating the lipid-lowering effectiveness of statin therapy.

    CONCLUSION: This study highlights the low utilization rate of statin therapy for primary prevention of CVD among patients prior to their first STEMI. Despite the proven effectiveness of statins in lowering cholesterol levels post-STEMI, there is a need to enhance awareness, adherence to guidelines, and efforts to achieve LDL-C targets through appropriate statin therapy.

    Medical conditions and systemic diseases often manifest as distinct facial characteristics, making identification of these unique features crucial for disease screening. However, detecting diseases using facial photography remains challenging because of the wide variability in human facial features and disease conditions. The integration of artificial intelligence (AI) into facial analysis represents a promising frontier offering a user-friendly, non-invasive, and cost-effective screening approach. This review explores the potential of AI-assisted facial analysis for identifying subtle facial phenotypes indicative of health disorders. First, we outline the technological framework essential for effective implementation in healthcare settings. Subsequently, we focus on the role of AI-assisted facial analysis in disease screening. We further expand our examination to include applications in health monitoring, support of treatment decision-making, and disease follow-up, thereby contributing to comprehensive disease management. Despite its promise, the adoption of this technology faces several challenges, including privacy concerns, model accuracy, issues with model interpretability, biases in AI algorithms, and adherence to regulatory standards. Addressing these challenges is crucial to ensure fair and ethical use. By overcoming these hurdles, AI-assisted facial analysis can empower healthcare providers, improve patient care outcomes, and enhance global health.

    Sodium hypochlorite (NaOCl) solution is a widely used irrigant in endodontics. However, it is highly cytotoxic and can have destructive effects on surrounding tissues when it is not confined to the root canal during irrigation. The extrusion of NaOCl beyond the confines of the root canal into the surrounding tissues or anatomical spaces is known as a NaOCl accident. The NaOCl accident is a serious iatrogenic mishap that can lead to severe tissue damage and complications, which can be life-threatening and/or cause long-term or permanent consequences with medico-legal implications. Therefore, this narrative review was conducted to provide clinicians with a comprehensive understanding of the mechanism and clinical aspects of NaOCl accidents. A literature search was conducted in various online databases using specific Medical Subject Headings (MeSH) and key search terms. The review included all categories of articles dealing with the NaOCl accident and available as full text. Additionally, a manual method of search was conducted by screening references of the included articles. Duplicate articles and articles available only as abstracts were excluded from the review. The included articles were reviewed, analyzed and discussed according to the following sections: causative factors; mechanism; clinical categorization; clinical manifestations; diagnosis, including history, clinical assessment and examination, clinical investigation, and differential diagnoses; and treatment planning of NaOCl accidents. This would enable clinicians to recognize and manage NaOCl accidents in the best possible manner and minimize their serious consequences. Future research should prioritize the identification of solutions or measures to address the challenges associated with conducting clinical or in vivo studies on NaOCl irrigation and extrusion.

    Glycyrrhiza uralensis Fisch (G. uralensis) is a key species for windbreak and sand fixation, possessing notable pharmacological and economic value. However, the yield of G. uralensis is considerably impacted due to its cultivation in arid, semi-arid, and salt-affected regions. Silicon (Si) has been reported to improve plant tolerance to drought and salt stress by regulating nitrogen and secondary metabolism. Herein, the effects of Si treatment on nitrogen and secondary metabolism of G. uralensis seedlings under drought (D), salt (S), and drought-salt (SD) stresses were investigated in combination with physiological and transcriptomic analyses. The results indicated that stress conditions significantly inhibited the growth of G. uralensis seedlings by suppressing nitrogen and secondary metabolism. Si treatment counteracted these inhibitions to some extent. Specifically, Si treatment increased soluble protein content by approximately 15% by regulating the nitrogen metabolism of G. uralensis under D stress. Furthermore, Si treatment elevated the content of glycyrrhetinic acid by about 89% under SD stress by increasing the content of primary metabolites and regulating the expression of enzymes involved in the biosynthesis of glycyrrhizic acid and liquiritin, including 3-hydroxy-3-methylglutaryl CoA reductase (HMGR), squalene synthase (SQS), and β-amyrin synthase (β-AS). In summary, our findings suggest that Si could alleviate the adverse effects induced by drought and/or salt stresses on the growth of G. uralensis seedlings by regulating nitrogen metabolisms, which further triggered the accumulation of secondary metabolites, ultimately improving the stress resistance of cultivated G. uralensis seedlings. This work provides direction for Si to improve stress resistance.

    Research on narrative skills in the Malay language is scarce for both typically developing (TD) and children with Developmental Language Disorders (DLD). This study examines the differences in narrative abilities of Malay-speaking school-age children with and without DLD. Fifteen Malay-speaking TD children and 15 children with DLD told four stories elicited using the Multilingual Assessment Instrument for Narrative (MAIN). Group comparisons were conducted in narrative production (story retelling and story generation) as well as in comprehension. We also examined the differences in both groups' story complexity (e.g. the combination of goals (G), attempts (A) and outcomes (O)). General microstructure features such as the total number of words (TNW), total number of sentences (TNS) and total number of different words (NDW) were also investigated. TD children outperformed children with DLD in both narrative production and comprehension. TD children constructed a higher combination of G, A, and O components than children with DLD. Children with DLD frequently produced G, A, and O in isolation in comparison to TD children. In language productivity and lexical complexity, TD children had a significantly higher frequency in TNW and NDW than children with DLD, resulting in longer narratives and higher use of different words than children with DLD. Distinct differences are found in the narrative profile of TD children and children with DLD. The results are relatively consistent with the findings of similar studies that utilised and adapted the MAIN in other languages. Clinical implications and recommendations are discussed.

    Malaria is endemic in poverty-stricken regions of the world, and most diagnosis reveal comorbidity with other infectious diseases some of which manifest as a deformity of the structural arrangement of the Red Blood Cells (RBCs) during thin blood smear microscopy. This common occurring deformity is termed rouleaux formation, and it is the stacking together of RBCs like chains of coins. The presence of rouleaux formation indicates either a bacterial infection, connective tissue disease, chronic liver disease, multiple myeloma or diabetes among others, it is a highly common occurrence in malaria infected patients and according to the international council for standardization of hematology (ICSH), microscopists are mandated to report its presence. Hence to develop unbiased automated malaria diagnostic systems capable of being deployed in malaria endemic regions, these systems need to be capable of identifying rouleaux formation and detecting malaria parasite within such type of RBC. Thus, this study developed a thin blood smear dataset with rouleaux formation RBCs infected with two species of malaria parasite: plasmodium falciparum and plasmodium malariae. YOLOv9s architecture was used to benchmark the dataset for the detection of plasmodium parasites and white blood cells in the developed dataset. Comparing the effect of using pretrained weights, YOLOv9s trained from scratch achieved a Precision, Recall and mAP50 of 75.4 %, 76.6 % and 80.3 % while YOLOv9s pretrained on the MS COCO dataset recorded an improvement in performance metrics with an increase in Precision by 0.4 %, an increase in Recall by 5.4 % and an increase in mAP50 by 2.5 .

    Mercury (Hg) is a global pollutant of widespread concern, and modern Hg levels have been much elevated compared to pre-industrial levels. The majority of environmental Hg assessment has occurred in the developed world within the temperate region, but recent years we have witnessed increases in research activities in polar, subtropical, and tropical biomes. East Asia is currently the biggest emitter of anthropogenic Hg, while intense research is ongoing in China, Korea, and Japan, relatively little has been done in the neighboring regions. Southeast (SE) Asia is a geographic region mostly within tropical biomes and neighboring two large global Hg emitters (i.e., China and India), and contains vast marine resources that would be prone to Hg contamination. The region consists of 10 countries of different economic and development status, and has a population near 700 million, a rapid industrialization and commercialization occurring in the region, including Hg-emitting activities such as coal burning and artisanal gold mining. Here, we identified 31 published studies since 1980s reporting marine Hg pollution in SE Asia, but the majority of the studies did not measure the neurotoxic form of Hg, methylmercury, while the majority of studies in SE Asia were concentrated in a few countries, namely Malaysia, Thailand, and Vietnam. Recommendations are provided to propel the Hg biogeochemical cycling studies in this rapidly developing region on the planet.
