    With environmental protection awareness increasing, green innovation has become a key way for enterprises to achieve sustainable development. Research trends on employee green behavior are an important basis for formulating green behavior incentive measures and a key foundation for further exploring green innovation. However, due to the large amount of literature on employee green behavior, obtaining research trends directly related to employee green behavior takes time and effort. To solve this problem, this paper takes the relevant published literature on research on employee green behavior from 2009 to 2024 as the research object. It uses CiteSpace software to study the research trends of employee green behavior from the number change analysis of published literature, distribution region analysis of published literature, influence analysis of main authors of published literature, keyword analysis, and high-frequency word analysis. The research results show that the publication of literature on employee green behavior has been steadily increasing since 2018, and the relevant research mainly focuses on the impact of green behavior motivations, green behavior emotional factors, green behavior performance results, green self-energy efficiency, and other aspects on employee green behavior. Based on the research results, further summaries and suggestions are given to provide references for the subsequent related research in this paper.

    Frequent detection of terbutaline in wastewater highlights its potential risks to human health associated in the environment. Exposure to terbutaline through contaminated water sources or food chain have adverse effects to human health. This work emphasized on the removal of terbutaline from wastewater using adsorption technology. Mechanochemically synthesized [Cu(INA)2] metal-organic frameworks (MOFs) and its magnetic composite ([Cu(INA)2]-MOF@Fe3O4) are designed with higher specific surface areas and tailored features to accommodate the molecular size and structure of terbutaline. Thus, batch experiment has been conducted using the [Cu(INA)2]-MOF and [Cu(INA)2]-MOF@Fe3O4 for the terbutaline adsorption. The adsorption efficiency achieved by the MOFs was 91.8% and 99.3% for the Cu(INA)2]-MOF and [Cu(INA)2]-MOF@Fe3O4 respectively. The optimum for the adsorption study included terbutaline concentration of 40 mg/L, adsorbent dose of 5 mg/L, pH of 11, temperature of 25 °C and equilibrium time of 40 min. The kinetics and isotherms have been described by pseudo-second order and Langmuir models, while the thermodynamics revealed the exothermic and spontaneous nature of the process. The promising performance of the MOFs is manifested on the ease of regeneration and reusability, achieving adsorption efficiency of 85.0% and 94.7% by the Cu(INA)2]-MOF and [Cu(INA)2]-MOF@Fe3O4, respectively at five consecutive cycles. The higher performance of the MOFs demonstrates their excellent potentialities for the terbutaline adsorption from the aqueous solution.

    Early Onset Parkinsonism (EOP) refers to parkinsonism occurring before the age of 50 years. The causes are diverse and include secondary and genetic causes. Secondary causes related to medications, inflammatory and infective disorders are mostly treatable and well recognized as they usually present with a relatively more rapid clinical course compared to idiopathic Parkinson's disease. Genetic causes of EOP are more challenging to diagnose especially as more of the non-PARK genes are recognized to present with typical and atypical parkinsonism. Some of the genetic disorders such as Spinocerebellar ataxia 2 (SCA2) and Spinocerebellar ataxia 3 (SCA3) may present with levodopa-responsive parkinsonism, indistinguishable from idiopathic Parkinson's disease. Additionally, some of the genetic disorders, including Wilson's disease and cerebrotendinous xanthomatosis (CTX), are potentially treatable and should not be missed. Due to the advent of next generating sequencing techniques, genetic analyses facilitate early identification and proper treatment of diverse causes of EOP. In this review, we outline the clinical approach of EOP highlighting the key clinical features of some of the non-PARK genetic causes of EOP and related investigations, which could assist in clinical diagnosis. This review also encompass genetic diagnostic approaches, emphasizing the significance of pretest counseling and the principles of bioinformatics analysis strategies.

    Studying differences in transcriptomes across various development stages of insects is necessary to uncover the physiological and molecular mechanism underlying development and metamorphosis. We here present the first transcriptome data generated under Illumina Hiseq platform concerning Zeugodacus tau (Walker) larvae from Nanchang, China. In total, 11,702 genes were identified from 9 transcriptome libraries of three development stages of Z. tau larvae. 7219 differentially expressed genes (DEGs) were screened out from the comparisons between each two development stages of Z. tau larvae, and their roles in development and metabolism were analyzed. Comparative analyses of transcriptome data showed that there are 5333 DEGs between 1-day and 7-day old larvae, consisting of 1609 up-regulated and 3724 down-regulated genes. Expressions of DEGs were more abundant in L7 than in L1 and L3, which might be associated with metamorphosis. Gene Ontology (GO) enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis suggested the enrichment of metabolic process. KOG annotation further confirmed that 20-hydroxyecdysone (20E) pathway related genes Cyp4ac1_1, Cyp4aa1, Cyp313a4_3 were critical for the biosynthesis, transport, and catabolism of secondary metabolites and lipid transport and metabolism. Expression patterns of 8 DEGs were verified using quantitative real-time PCR (RT-qPCR). This study elucidated the DEGs and their roles underlying three development stages of Z. tau larvae, which provided valuable information for further functional genomic research.

    BACKGROUND & AIMS: Metabolic dysfunction-associated steatohepatitis (MASH) and fibrotic MASH are significant health challenges. This multi-national study aimed to validate the acMASH index (including serum creatinine and aspartate aminotransferase concentrations) for MASH diagnosis and develop a new index (acFibroMASH) for non-invasively identifying fibrotic MASH and exploring its predictive value for liver-related events (LREs).

    METHODS: We analyzed data from 3004 individuals with biopsy-proven metabolic dysfunction-associated steatotic liver disease (MASLD) across 29 Chinese and 9 international cohorts to validate the acMASH index and develop the acFibroMASH index. Additionally, we utilized the independent external data from a multi-national cohort of 9034 patients with MASLD to examine associations between the acFibroMASH index and the risk of LREs.

    RESULTS: In the pooled global cohort, the acMASH index identified MASH with an area under the receiver operating characteristic curve (AUROC) of 0.802 (95% confidence interval [CI], 0.786-0.818). The acFibroMASH index (including the acMASH index plus liver stiffness measurement) accurately identified fibrotic MASH with an AUROC of 0.808 in the derivation cohort and 0.800 in the validation cohort. Notably, the AUROC for the acFibroMASH index was 0.835 (95% CI, 0.786-0.882), superior to that of the FAST score at 0.750 (95% CI, 0.693-0.800; P < .01) in predicting the 5-year risk of LREs. Patients with acFibroMASH >0.39 had a higher risk of LREs than those with acFibroMASH <0.15 (adjusted hazard ratio, 11.23; 95% CI, 3.98-31.66).

    CONCLUSIONS: This multi-ethnic study validates the acMASH index as a reliable, noninvasive test for identifying MASH. The newly proposed acFibroMASH index is a reliable test for identifying fibrotic MASH and predicting the risk of LREs.

    BACKGROUND AND AIM: Patient safety culture is crucial for every health care institution, as a lack of it may harm patients seeking treatment. The current study aimed to identify the level of safety culture and assess the knowledge, attitude, and perception of patient safety culture among healthcare providers (HCPs') in tertiary hospital settings.

    METHODS: A cross-sectional study was conducted among HCPs from two private tertiary hospitals in Johor and Selangor. A structured validated questionnaire, including the Hospital Survey on Patient Safety Culture, was used to assess the level of patient safety culture in these hospitals.

    RESULTS: In this study, the calculated sample size was 320, and all 550 eligible participants from both hospitals were approached to participate. However, only 158 responded, resulting in a response rate of 49.38%. The majority of the HCPs (n = 110; 69%) rated their hospital as very good or excellent in maintaining an overall patient safety culture. The study revealed that communication about the errors (PRR = 80) and organizational learning and continuous improvement (PRR = 74) were good in their hospital settings. However, staffing and work pace (PRR = 28), response to errors (PRR = 40), reporting patient safety events (PRR = 48), and handoffs and information exchange (PRR = 39) were inadequate. These findings indicate the negative attitudes among HCPs and the need for further improvement to maintain a culture of patient safety.

    CONCLUSION: HCPs in the study settings had optimal knowledge but negative attitudes towards the culture of patient safety in their organization. Inadequate staffing, work pace, and a lack of response to mistakes were commonly observed, which may increase the chances of errors and pose health threats to patients that need to be addressed immediately. Every healthcare organization is urged to address the issue of patient safety culture as a matter of urgency.

    This narrative review describes pneumococcal serotype prevalence for invasive disease and carriage and antibiotic resistance among specimens collected from children in countries across South and Southeast Asia from 2012 to 2024. Literature search retrieved 326 articles; 96 were included. The prevalence of pneumococcal serotypes varied geographically and over time after introduction of pneumococcal conjugate vaccine. Serotypes common in both pneumococcal carriage and disease were 6A, 6B, 14, 15B/15C, 19F, and 23F; serotypes 1, 3, 5, 19A, 15A, 10A, and 35B were also common in disease. Most of these serotypes are included in the 13-valent and 10-valent PCV. Carriage and disease isolates remained generally highly susceptible to vancomycin (mostly 100%) and levofloxacin (mostly >97%). These findings indicate that vaccine-preventable serotypes contribute significantly to pneumococcal disease burden in children in South and Southeast Asia. Consistency of national immunization programs with World Health Organization recommendations may reduce rates of pneumococcal disease in this region.

    STUDY OBJECTIVES: To develop a comprehensive Asian adult sleep medicine fellowship training curriculum to address the significant disparities in sleep medicine training across Asia, guided by the principle of "One Curriculum, Many Contexts," providing a standardized yet adaptable framework for sleep medicine education across the diverse healthcare landscapes of Asian countries.

    METHODS: The curriculum development process involved a gap analysis, comprehensive literature review, and expert consensus through a modified RAND appropriateness method (RAM)/Delphi survey.

    RESULTS: The curriculum offers two flexible tracks: a one-year program (Track A) and a two-year program (Track B), accommodating varied educational pathways and healthcare system structures across Asia. Key features of the curriculum include detailed learning outcomes, competency-based educational content, and recommendations for teaching and learning activities. The assessment strategy incorporates summative and formative methods, with standard setting and program evaluation guidelines. The curriculum also provides recommendations for program accreditation, fellow-faculty ratios, and funding considerations.

    CONCLUSIONS: The Asian adult sleep medicine fellowship training curriculum provides a standardized yet adaptable framework for sleep medicine education across diverse Asian healthcare landscapes. By emphasizing flexibility and customization while maintaining high training standards, the curriculum aims to bridge the gap in sleep medicine training across Asia, ultimately improving the quality of sleep healthcare and patient outcomes throughout the region.

    BACKGROUND: This study aimed to compare the effectiveness of membrane sweeping and transcervical Foley catheters for the induction of labor after one previous cesarean delivery.

    METHODS: An open-label, prospective, randomized controlled trial was performed at Sibu Hospital, Sarawak, Malaysia between 15th February 2018 and 30th August 2018. Pregnant women aged 18 or above at term who had one previous uncomplicated lower segment cesarean section and required induction of labor were randomized to membrane sweeping or transcervical Foley catheter insertion.

    RESULTS: A total of 60 women were recruited in the study, of whom 30 were randomized to the membrane sweeping group and 30 to the Foley catheter group. The number of women who achieved a Bishop Score ≥8 was significantly higher in the Foley catheter arm than in the membrane sweeping arm (76.7% versus 43.3%; P=0.008). Compared with membrane sweeping, transcervical Foley catheter insertion significantly improved Bishop scores and allowed more women to achieve a favorable cervix that permitted an amniotomy by 48 hours of labor induction (P<0.05). The mode of delivery, intrapartum oxytocin use, maternal complications and neonatal outcomes were similar in both groups. No women had a uterine rupture or uterine hyperstimulation.

    CONCLUSIONS: Although transcervical Foley catheter insertion is superior to membrane sweeping in terms of the efficacy of labor induction, both methods did not show a statistically significant difference in vaginal delivery rates and their overall complication rates were similar.

    Oral mucositis (OM) remains a debilitating side effect in patients undergoing cancer therapy. DNA damage and oxidative stress generated by radiation and/or chemotherapy activate key inflammatory pathways, ultimately resulting in the destruction of the epithelial barrier, leading to microbial colonization, and ulceration. These ulcerative lesions are often extremely painful, compromising nutrition and oral hygiene, requiring intravenous nutritional support, resulting in longer periods of hospitalization and increased cost. Ulcers often increase the risk of secondary infection, disrupting cancer therapy and patient prognosis. Despite these issues, there is no approved therapy to mitigate OM. Ultrasmall (

    The potential of two different aquatic macrophytes, Azolla pinnata R.Br. and Lemna minor L., to treat livestock wastewater through phytoremediation was investigated. The physiological analysis includes the removal efficiency of manganese (Mn) from livestock wastewater by AAS. Morphological observation was performed by using a scanning electron microscope (SEM) and visual observation. RAPD analysis was applied to observe the DNA profile. It was observed that the removal efficiency of Mn was higher in L. minor with a 92% removal rate, while in A. pinnata RE, it was at a 77% rate. The higher removal rate of Mn by L. minor showed that plants had a significant impact on the removal of heavy metals, with a p ≤ 0.05. Retention time and the removal of heavy metals were found to be positively correlated. As early as 24 h after exposure to livestock wastewater (LW), the stomata on the leaves of A. pinnata and L. minor have both shrunk, and the root surfaces have shortened. According to the RAPD analysis, A. pinnata only shows an increase in band intensities and no polymorphism, whereas L. minor has 19% polymorphisms that indicate higher tolerance as hyperaccumulators. As a conclusion, L. minor showed no signs of necrosis and performed more efficiently as a hyperaccumulator in LW, with a higher removal efficiency.

    Detection of Strogyloides-specific IgG antibodies in urine and serum has been used in diagnostic and epidemiological studies on strongyloidiasis. However, the usefulness of these assays in assessing responses to anthelmintic treatment is unclear. Thus, we evaluated the diagnostic performance and temporal profiles of Strongyloides-specific IgG antibodies in a cohort of participants at baseline and post-treatment. The participants were prospectively screened for baseline parasitic infections by fecal examination [agar plate culture technique (APCT) and formalin-ethyl acetate concentration technique (FECT)] and digital droplet polymerase reaction (ddPCR) for Strongyloides stercoralis. At each sampling point, Strongyloides-specific IgG in urine and serum were measured by an in-house S. ratti-based enzyme-linked immunosorbent assay (ELISA). At baseline, 169 of 351 participants (48.1%) had S. stercoralis infection by the combined fecal examination and ddPCR. The diagnostic sensitivities of IgG in urine and serum were 91.1% and 88.2%, respectively. The participants were given treatment with a single oral dose of ivermectin (IVM, 200 μg/kg) and were followed up by fecal and immunological diagnosis at 3 to 18 months post-treatment. The cure rate of IVM treatment evaluated by APCT and ddPCR was 88.3% at three months post-treatment. The profiles of IgG in urine in the curative treatment group showed a significant trend of decline with time post-treatment (Kruskal-Wallis test = 113.4-212.6, p value < 0.0001) and the lowest levels were seen 12 months post-treatment. The treatment response (> 50% reduction in urinary IgG antibody units) was 100%, and conversion from positive to negative results was 65.4%. The treatment response and conversion to negative assessed by serum IgG-ELISA were similar to those by urine IgG-ELISA. The results from this long-term diagnostic study highlight the utility of urinary IgG and serum IgG for screening and monitoring treatment outcomes in strongyloidiasis.

    The popularity of cloud computing (CC) has increased significantly in recent years due to its cost-effectiveness and simplified resource allocation. Owing to the exponential rise of cloud computing in the past decade, many corporations and businesses have moved to the cloud to ensure accessibility, scalability, and transparency. The proposed research involves comparing the accuracy and fault prediction of five machine learning algorithms: AdaBoostM1, Bagging, Decision Tree (J48), Deep Learning (Dl4jMLP), and Naive Bayes Tree (NB Tree). The results from secondary data analysis indicate that the Central Processing Unit CPU-Mem Multi classifier has the highest accuracy percentage and the least amount of fault prediction. This holds for the Decision Tree (J48) classifier with an accuracy rate of 89.71% for 80/20, 90.28% for 70/30, and 92.82% for 10-fold cross-validation. Additionally, the Hard Disk Drive HDD-Mono classifier has an accuracy rate of 90.35% for 80/20, 92.35% for 70/30, and 90.49% for 10-fold cross-validation. The AdaBoostM1 classifier was found to have the highest accuracy percentage and the least amount of fault prediction for the HDD Multi classifier with an accuracy rate of 93.63% for 80/20, 90.09% for 70/30, and 88.92% for 10-fold cross-validation. Finally, the CPU-Mem Mono classifier has an accuracy rate of 77.87% for 80/20, 77.01% for 70/30, and 77.06% for 10-fold cross-validation. Based on the primary data results, the Naive Bayes Tree (NB Tree) classifier is found to have the highest accuracy rate with less fault prediction of 97.05% for 80/20, 96.09% for 70/30, and 96.78% for 10 folds cross-validation. However, the algorithm complexity is not good, taking 1.01 seconds. On the other hand, the Decision Tree (J48) has the second-highest accuracy rate of 96.78%, 95.95%, and 96.78% for 80/20, 70/30, and 10-fold cross-validation, respectively. J48 also has less fault prediction but with a good algorithm complexity of 0.11 seconds. The difference in accuracy and less fault prediction between NB Tree and J48 is only 0.9%, but the difference in time complexity is 9 seconds. Based on the results, we have decided to make modifications to the Decision Tree (J48) algorithm. This method has been proposed as it offers the highest accuracy and less fault prediction errors, with 97.05% accuracy for the 80/20 split, 96.42% for the 70/30 split, and 97.07% for the 10-fold cross-validation.

    There are scant LGBT+ studies in Southeast Asia exploring mental health differences across multiple social identities. Using data from the Malaysian KAMI Survey (n = 718), we conducted bivariate regression analyses to investigate the association between sociodemographic backgrounds and the prevalence of depression, anxiety, non-suicidal self-injury, and suicidality. Results showed that younger participants, those questioning their sexual orientation (compared to gay or lesbian), cisgender women, trans men, and non-binary individuals (compared to cisgender men) reported significantly higher levels of mental ill-health. Our intercategorical analysis builds a foundation for future intersectional-based research in response to public health challenges for vulnerable LGBT+ groups.

    Searches for pair-produced multijet signatures using data corresponding to an integrated luminosity of 128  fb^{-1} of proton-proton collisions at sqrt[s]=13  TeV are presented. A data scouting technique is employed to record events with low jet scalar transverse momentum sum values. The electroweak production of particles predicted in R-parity violating supersymmetric models is probed for the first time with fully hadronic final states. This is the first search for prompt hadronically decaying mass-degenerate higgsinos, and extends current exclusions on R-parity violating top squarks and gluinos.

    A key driver of obesity and diet-related illness globally has been the increased consumption of ultra-processed foods (UPFs). This paper aimed to identify the key actors, structures, incentives, and dynamics that characterize the global UPF system and have led to the dominance of UPFs in population diets. Based on a narrative review and using a systems thinking approach, we developed a causal loop diagram (CLD) of the global UPF system. The CLD comprises nine reinforcing loops: the commodification of diets; increasing market concentration; increasing UPF levels in food retail environments; the financialization of diets; direct corporate political influence; increasing capture of science, public opinion, and policy narratives; shifts from private to public food governance; state accommodation of corporate power; and an "agricultural regime" promoting the production of relatively cheap UPF inputs. The CLD also contains two balancing loops relating to market saturation and public health policies that curb UPF consumption and a countervailing reinforcing loop depicting other forms of food systems in tension with the UPF system. This study suggests the need for innovative and expansive government policies to protect and promote healthy, sustainable diets and coordinated advocacy efforts among those seeking to challenge the exploitative aspects of corporate food systems.

    INTRODUCTION: Treatment combination of pembrolizumab plus platinum and 5-fluorouracil (PF) has increased the survival of recurrent or metastatic (R/M) head and neck squamous cell carcinoma (HNSCC). The combination of platinum and gemcitabine (PG) has been shown to be superior to PF in the treatment of R/M nasopharyngeal carcinoma patients. Therefore, we hypothesise that the combination of pembrolizumab with PG would be comparable to pembrolizumab with PF as a first-line treatment in R/M HNSCC.

    METHODS AND ANALYSIS: This is an open-label, multicentre, single-arm, phase 2 study of pembrolizumab plus PG for first-line treatment in subjects with R/M HNSCC in Malaysia. The study is conducted using the Optional Simon optimal 2-stage design. At the initial stage, 26 subjects will be enrolled and if seven or more patients achieve an objective response rate (ORR), then 63 patients will be enrolled. Subjects will be given pembrolizumab 200 mg3 every 3 weeks up to 35 cycles in combination with chemotherapy for up to six cycles of platinum (either cisplatin at 35 mg/m2 intravenous on day 1 and day 8 or carboplatin at area under the curve 5 intravenous on day 1 of each 3-week cycle) and gemcitabine at 1250 mg/m2 intravenous on days 1 and 8 of a 3-week cycle. The primary end point is the ORR as per Response Evaluation Criteria in Solid Tumors 1.1. Secondary end points include the overall survival, progression free survival, response duration and safety. The exploratory objectives include relationships of microbiome profiles, prognostic and predictive biomarkers with the clinical responses.

    ETHICS AND DISSEMINATION: The study was approved by the ethics committee of the University Malaya Medical Centre (202213-10884). Findings will be disseminated through conference presentations and peer review publications.
