    INTRODUCTION: Prior to any surgical intervention, obtaining informed consent is necessary. In situations where patients are unable to provide informed consent due to mental incapacity or reduced consciousness, the responsibility falls on surrogate decision-makers, typically family members. This predicament commonly arises during neurosurgical emergencies. Various types of surgical emergencies exist, each with its own classification. In cases of life-threatening neurosurgical emergencies and in the absence of next of kin, two consultants have the authority to decide and grant surgical consent. However, for urgent and semi-emergency surgical cases, obtaining consent from the next of kin is crucial. The conventional requirement for the physical presence of the next of kin at the hospital often causes delays in the procedure. This study aims to explore alternative methods for efficiently and compliantly securing this consent for urgent and semi-emergency neurosurgical cases.

    MATERIALS AND METHODS: A prospective, observational crosssectional survey was conducted from 1st May 2022 to 31st December 2022 at the University of Malaya Medical Centre, Kuala Lumpur. This survey included all neurosurgical patients aged 18 and above requiring urgent and semiemergency surgery. The next of kin were interviewed using a standardised questionnaire to obtain their perspectives on the effectiveness of the current consenting process, as well as to explore potential alternative methods for obtaining consent. Data were analysed using IBM SPSS Statistics.

    RESULTS: The survey had 103 responses. The analysis revealed that the most common semi-emergency surgical procedures were craniotomy (22 cases) and external ventricular drain insertion (18 cases), followed by burr hole and drainage (14 cases). The most common primary diagnosis that needed urgent intervention was acute hydrocephalus. Interestingly, more than half of the patients (58 cases, 56.3%) had to wait for over 30 minutes to obtain consent from their next of kin prior to surgery. The next of kin interviewed had an age range of 25 to 72 years. The relationships of the next of kin were children (33 subjects), spouses (26 subjects), siblings (25 subjects), and parents (16 subjects) of the patients. Additionally, 96.1% of the respondents owned a smartphone with a mobile internet data connection, and 85.4% had internet connectivity at home. The most preferred method of telecommunication for this exercise was via WhatsApp. An interesting finding was the association between the level of trust in medical professionals and the preferred consent method. It was discovered that individuals who preferred physical consent had lower trust in the hospital and doctors, while those who preferred remote consent had higher trust.

    CONCLUSION: The urban Malaysian population are ready to embrace telecommunication for next-of-kin consent in semiemergency neurosurgical scenarios. These findings form a precursor to further studies to develop algorithms for a secure remote digital surgical consenting platform for urgent or semi-emergency surgical cases.

    INTRODUCTION: Critical coronavirus disease (COVID-19) patients have a high mortality rate. To identify high-risk patients, first-level healthcare facilities can use the neutrophil-lymphocyte ratio (NLR) and the plateletlymphocyte ratio (PLR) as prognostic markers. We aimed to assess the NLR and the PLR profile in critically ill COVID-19 patients to predict disease severity.

    MATERIALS AND METHODS: This descriptive retrospective study featured 221 patients diagnosed with clinically critical COVID-19 from August 2021 to March 2022 in the Intensive Care Unit (ICU) of RSUP Dr. M. Djamil, Padang, Indonesia. The study employed a total sampling technique to collect data from medical records in the hospital. Patients aged 18 years or older who underwent testing for leukocytes, platelets, neutrophils, and lymphocytes were included in the study. We analysed the data using descriptive univariate analysis. Then, the NLR and PLR of the patients were statistically compared based on comorbidities and coincidence.

    RESULTS: According to the study, most patients with critically ill COVID-19 exhibited high levels of NLR (88.2%) and PLR (71.1%). The severe COVID-19 patients with comorbidity of kidney disease had the highest NLR (Mean ± SD) of 31.74 ± 27.95 (p-value <0.001) and the highest mean PLR (Mean ± SD) of 469.33 ± 362.95 (p-value 0.001).

    CONCLUSION: Our findings showed a significantly higher NLR and PLR in patients with critically ill COVID-19, particularly in patients with comorbidity of kidney disease. Thus, elevated levels of NLR and PLR were identified as potential prognostic markers for predicting disease severity in COVID-19 patients, especially those with kidney comorbidity.

    INTRODUCTION: Aplastic anaemia (AA) is a rare disorder of bone marrow failure, characterized by bone marrow hypocellularity with pancytopenia. The annual incidence rates of AA in Asia are observed to be two to three times higher than Europe and North America. Since the introduction of immunosuppressive therapy (IST) and of allogenic stem cell transplant (SCT), the outcome of severe AA has significantly improved. We conducted a 12-year multi-centre retrospective study among the adult AA population in Sabah and Sarawak.

    MATERIALS AND METHODS: A total of 119 AA patients had been identified from hospital records of the involved sites, namely Queen Elizabeth Hospital in Sabah, Sarawak General Hospital, Sibu Hospital, Miri Hospital and Bintulu Hospital in Sarawak from Jan 2006 to Dec 2017.

    RESULTS: The median age at diagnosis was 46 years, and native ethnic group from Sabah, Kadazan-Dusun, recorded the highest percentage of 41.2%, which could be explained by higher frequency of HLA-DRB1*15:01, an alelle linked to increased risk of AA, among this ethnic group. The majority of patients (59.7%) received cyclosporine (CsA) as monotherapy or in combination with other non-IST agents such as danazol, which was instituted in 48.7% of the patients, while a third of them (33.7%) received antithymocyte globulin (ATG) therapy with or without CsA, and 12.4% underwent allogenic SCT. The five-year overall survival (OS) for all AA patients was 76.1%. Elderly patients >60 years old and those with severe disease had more inferior 5-year survival.

    CONCLUSION: A prospective study is warranted to determine the true incidence rate, epidemiological distributions, treatment outcome and overall survival of AA patients in Malaysia. Establishment of allogenic SCT in East Malaysia is imperative to make this curative therapy more accessible to patients with severe disease and improve the outcome.

    INTRODUCTION: The weight of an infant at the time of birth is an indicator of its health. Infants with low birth weight (LBW) are at a higher risk of neonatal mortality and morbidity as well as stunted growth. Low birth weight (LBW) remains a public health concern in developing countries, such as Indonesia. In fact, the neonatal mortalities and morbidities that occur as a consequence of LBW can be prevented by addressing the relevant risk factors. It is believed that by identifying these risk factors, prevention and management efforts can be efficiently and effectively implemented to reduce incidences of LBW (LBWIs). As such, the present study determined the factors affecting LBWIs in a rural setting in Pontianak City, Indonesia.

    MATERIALS AND METHODS: This is a retrospective unmatched case-control study. The required data was obtained from the medical records maintained by the University Tanjungpura Hospital, Pontianak City, Indonesia. Simple random sampling was used to select and equally divide the 60 chosen respondents into LBW case and normal birth weight control groups.

    RESULTS: Mothers with low educational levels had a 1.5 times greater chance of giving birth to LBW babies. The results of the multivariate analysis also revealed a correlation between gestational age (GA), incidence of premature rupture of membranes (PROM), and intrauterine growth restriction (IUGR) and that their combined effects that contributed to 56% of LBWIs.

    CONCLUSION: Low maternal education level, low gestational age, IUGR, and premature rupture of membranes contribute to LBW babies. This study recommends that it is necessary to educate women of childbearing age about routine antenatal care checks to identify risk factors that can lead to LBW.

    INTRODUCTION: Anaesthesiology is a high-demand speciality with 24-hour on-call shifts, which can lead to significant stress and impaired sleep quality among anaesthetists. Nonpharmacological interventions like acupuncture have been widely explored for stress relief. This study aims to evaluate the impact of transcutaneous electrical acupoint stimulation (TEAS) on physiological parameters, specifically heart rate variability (HRV) and sleep quality, in anaesthesiology trainees following 24-hour on-call duty.

    MATERIALS AND METHODS: A total of 38 anaesthesiology trainees, following 24-hour ICU on-call shifts, were recruited for this single-centre cross-sectional clinical trial. The participants were required to complete two 24-hour on-call duties. Demographic data and baseline sleep quality assessments were collected following the first on-call duty. Upon completion of the second on-call shift, participants underwent 20 minutes of TEAS at bilateral PC6 (Neiguan), LI4 (Hegu), LR3 (Taichong), and ST41 (Jiexi) points. Heart rate variability (HRV) parameters, blood pressure, and heart rate were recorded before and after TEAS. Post-TEAS sleep quality was assessed following an overnight rest.

    RESULTS: The results demonstrated a significant reduction in systolic blood pressure compared to baseline (109.5±8.9 vs 111.9±10.1 mmHg, p = 0.006), as well as a significant decrease in diastolic blood pressure (69.3±8.0 vs 70.9±9.0 mmHg, p = 0.037) and heart rate (65.8±9.2 vs 67.4±9.8 bpm, p = 0.034). There was significant improvement in all aspects of sleep quality (p < 0.001). However, no statistically significant changes were observed in heart rate variability (HRV) parameters, including high-frequency (HF) power, lowfrequency (LF) power, and the LF/HF ratio.

    CONCLUSION: TEAS may offer potential benefits in managing cardiovascular stress and improving sleep quality in highstress environments, such as post-call recovery. Nevertheless, its impact on autonomic nervous system regulation, as reflected by HRV, appears limited.

    INTRODUCTION: To determine the level of good awareness and knowledge on glaucoma and their associated factors as well as the effectiveness of the glaucoma educational intervention among the working adults in northeast of Malaysia.

    MATERIALS AND METHODS: Participants from the governmental departments were recruited and divided into intervention group and control group. A translated and validated questionnaire on awareness and knowledge related to glaucoma were used. Educational interventions were given for both groups. Post-test assessments were completed at one month and three months post intervention.

    RESULTS: A total of 202 participants enrolled for the study (102 intervention group and 100 control group). 64.9% of the participants were aware of glaucoma and 49% of the participants had good knowledge score on glaucoma. Higher educational attainments (bachelor and diploma holders) were the only factors significantly associated with good glaucoma knowledge (p <0.001). There was significant increase in the proportion of good glaucoma knowledge in the intervention group one month after the educational intervention (p < 0.001) and the effect persisted after three months (p < 0.003). There was also significantly higher proportion of good post-test glaucoma knowledge between intervention and control group (p = 0.003).

    CONCLUSION: Although the public was well aware of glaucoma, there was relatively little understanding of the condition. Educational interventions can be effective to bridge the gap in promoting the glaucoma awareness and better understanding of glaucoma.

    INTRODUCTION: Interleukin (IL)-41, a type of cytokine also known as Metrnl, is involved in the pathogenesis of various inflammatory and immune-related diseases. However, its role in Ankylosing Spondylitis (AS), a field yet to be explored, remains a mystery. This study therefore assesses the diagnostic utility of IL-41 in patients with AS and examines the correlations among IL-41 levels, disease activity, and patients' demographic and clinical data. Such novel insights could have significant implications for the diagnosis and management of AS.

    MATERIALS AND METHODS: Eighty-eight patients diagnosed with AS were enrolled from the Rheumatology Unit at Baghdad Teaching Hospital. Participants were categorized into two groups based on disease status: inactive (n = 44) and active (n = 44). Additionally, 44 matched healthy individuals were included as controls. Comprehensive medical histories were obtained, including disease duration, body mass index, sex, and age. Laboratory parameters related to the disease-such as C-reactive protein, human leukocyte antigen (HLA-B27), and rheumatoid factor-were also measured. Serum IL-41 levels were quantified using an enzyme-linked immunosorbent assay.

    RESULTS: The study revealed a significant difference in levels of IL-41 in patients with AS (17.721±0.705 ng/L) compared to controls (8.495±0.984 ng/L; P = 0.009). The mean serum IL-41 concentration was highest in the active group (23.037±5.268 ng/L), followed by the inactive group (12.411±1.672 ng/L; p = 0.001) and controls (8.495±0.984 ng/L). Serum IL-41 levels demonstrated strong validity for diagnosing AS, with a cutoff value of ≥ 9.35 ng/mL and an area under the curve of 0.991. The sensitivity, specificity, and accuracy were 97.7%, 79.5%, and 92.38%, respectively (p = 0.002).

    CONCLUSIONS: IL-41 is a potential new diagnostic biomarker for AS and associated with patient's disease activity. These insights could potentially transform the way we diagnose and manage AS, offering new avenues for improved patient care and outcomes.

    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.

    Development of Prostate Specific Membrane Antigen (PSMA)-targeted radiopharmaceuticals for theranostics has changed the treatment landscape for patients with metastatic castration-resistant prostate cancer (mCRPC). The emerging use of [225Ac]Ac-PSMA-RLT has been effective and safe for the treatment of mCRPC. Nevertheless, challenges with the nuclear recoil of [225Ac]Actinium radionuclides, which may release the daughter radionuclide from the radiopharmaceutical and lead to unnecessary irradiation of other organs, poses threats such as organ dysfunction. Therefore, this short communication aims to highlight the current situation in Malaysia and explain the solutions by using a risk-based approach analysis for the inhouse preparation.

    In a dynamic healthcare environment, patient safety is crucial. A "Conscious Actions Reduce Errors" (C.A.R.E) approach is needed to safeguard safety and reduce medical errors. The dual process theory highlights two thinking modes: intuitive (fast, automatic) and analytical (slow, deliberate). Intuitive thinking, though quick and often effective, can lead to cognitive biases like anchoring and availability heuristics. A C.A.R.E approach incorporating tools like the TWED checklist (Threat, What if I'm wrong? What else?, Evidence, Dispositional factors) and Shisa Kanko (Japanese method of pointing and calling) can help to improve decision-making and action precision in clinical settings.

    PURPOSE: Dietary fiber intake may influence the risk and severity of atopic dermatitis (AD), a common chronic allergic skin condition. This cross-sequential study investigated the association between dietary fiber intake and various characteristics of AD, including house dust mites (HDM) allergy and dry skin, in 13,561 young Chinese adults (mean years = 22.51, SD ± 5.90) from Singapore and Malaysia.

    METHODS: Dietary habits were assessed using a validated semi-quantitative, investigator-administered food frequency questionnaire from the International Study of Asthma and Allergies in Childhood. We derived an amount-based dietary index to estimate fiber intake while studying its correlation with probiotic drinks intake. AD status was determined by skin prick tests for HDM and symptomatic histories of eczema. Multivariable logistic regression analysis, adjusting for demographic, genetic predisposition, body mass index and lifestyle factors, and synergy factor analysis were used to explore the association and interaction of dietary factors on disease outcomes.

    RESULTS: High fiber intake (approximately 98.25 g/serving/week) significantly lowered the associated risks for HDM allergy (Adjusted Odds Ratio [AOR]: 0.895; 95% Confidence Intervals [CI]: 0.810-0.989; adjusted p-value

    To assess the sources, levels, spatial distributions and exposure to human health, the concentration of heavy metals Pb, Cu, Mn, Zn, and Fe in the sand/sediment of the Parki Beach area of Anowara, Chattogram, Bangladesh are determined using Atomic Absorption Spectroscopy (AAS) for the first time. A total of 40 surface and subsurface sand and sediment samples were collected from 20 different sampling points along the 15 km long Parki Beach area, Bangladesh. Average concentrations of Pb, Cu, Mn, Zn and Fe in surface samples are 14.60, 10.10, 283, 407 and 25,256 mg/kg respectively and 9.95, 4.20, 193, 156.6 and 24,404 mg/kg for sub-surface samples, respectively, which shows that the values are higher in surface samples than those in sub-surface samples. According to the Consensus-Based Sediment Quality Guidelines (CBSQG), the northern part of the beach becomes moderately polluted by Mn and Fe, and a smaller area of the southern part is highly polluted by Zn. The average Contamination Factor (CF) of Zn was greater than 1(CF > 1), while the CF of other metals was less than 1(CF

    PURPOSE: Conventional obstructive sleep apnea (OSA) diagnosis via polysomnography can be costly and inaccessible. Recent advances in artificial intelligence (AI) have enabled the use of craniofacial photographs to diagnose OSA. This meta-analysis aims to clarify the diagnostic accuracy of this innovative approach.

    METHODS: Two blinded reviewers searched PubMed, Embase, Scopus, Web of Science, and IEEE Xplore databases, then selected and graded the risk of bias of observational studies of adults (≥ 18 years) comparing the diagnostic performance of AI algorithms using craniofacial photographs, versus conventional OSA diagnostic criteria (i.e. apnea-hypopnea index [AHI]). Studies were excluded if they detected apneic events without diagnosing OSA. AI models evaluated with a random split test set or k-fold cross-validation were included in a Bayesian bivariate meta-analysis.

    RESULTS: From 5,147 records, 6 studies were included, containing 10 AI models trained/tested on 1,417/983 participants. The risk of bias was low. AI trained on craniofacial photographs achieved a pooled 84.9% sensitivity (95% credible interval [95% CrI]: 77.1-90.7%) and 71.2% specificity (95% CrI: 60.7-81.4%). Bayesian meta-regression identified deep learning (convolutional neural networks) as the most accurate AI algorithm (91.1% sensitivity, 79.2% specificity) comparable to home sleep apnea tests. AHI cutoffs, OSA prevalence, feature engineering, input data, camera type and informativeness of Bayesian prior did not alter diagnostic accuracy. There was no substantial publication bias.

    CONCLUSION: AI trained on craniofacial photographs have high diagnostic accuracy and should be considered as a low-cost OSA screening tool. Future work focused on deep learning using smartphone images could improve the feasibility of this approach in primary care.

    The European Society for Medical Oncology (ESMO) Clinical Practice Guidelines for the diagnosis, treatment and follow-up of patients with oncogene-addicted metastatic non-small-cell lung cancer (mNSCLC), published in January 2023, was modified according to previously established standard methodology, to produce the Pan-Asian adapted (PAGA) ESMO consensus guidelines for the management of Asian patients with oncogene-addicted mNSCLC. The adapted guidelines presented in this manuscript represent the consensus opinions reached by a panel of Asian experts in the treatment of patients with oncogene-addicted mNSCLC representing the oncological societies of China (CSCO), Indonesia (ISHMO), India (ISMPO), Japan (JSMO), Korea (KSMO), Malaysia (MOS), the Philippines (PSMO), Singapore (SSO), Taiwan (TOS) and Thailand (TSCO), co-ordinated by ESMO and the Korean Society for Medical Oncology (KSMO). The voting was based on scientific evidence and was independent of the current treatment practices, drug access restrictions and reimbursement decisions in the different regions of Asia. The latter are discussed separately in the manuscript. The aim is to provide guidance for the optimisation and harmonisation of the management of patients with oncogene-addicted mNSCLC across the different regions of Asia, drawing on the evidence provided by both Western and Asian trials, while respecting the differences in screening practices, molecular profiling and age and stage at presentation. Attention is drawn to the disparity in the drug approvals and reimbursement strategies between the different regions of Asia.

    BACKGROUND: Dengue remains a global health challenge with limited treatment options, highlighting the need for effective vector control strategies. The introduction of Wolbachia pipientis into Aedes aegypti populations has shown success in reducing dengue transmission across global field trials. However, the spillover effectiveness of the technology on untreated areas is not well-known. This study estimates the spillover protective effectiveness (PE) of Wolbachia-mediated introgression on dengue.

    METHODS: We used the synthetic control method (SCM) under assumption of partial interference to evaluate the direct and spillover PEs of Wolbachia-mediated introgression in a long-running operational trial of the intervention in Malaysia. Synthetic controls (SCs), which comprise of a weighted sum of non-spillover controls, were constructed for each directly-treated and spillover site in the pre-intervention period to account for historical imbalances in dengue risk and risk trajectories. SCs were compared to directly/spillover-treated sites to estimate the impact of Wolbachia-introgression on dengue incidence across each site, calendar year and intervention time. Robustness checks, including visual inspections, root-mean-square error (RMSE) calculations, in-space and in-time placebo checks, and permutation tests, were used to inspect the model's ability in attributing dengue incidence reductions to the Wolbachia interventions.

    FINDINGS: The direct and spillover PEs of Wolbachia on dengue incidence were expressed as a percentage reduction of dengue incidence, or the absolute case reductions, by comparing SCs to actual intervention/spillover sites. Findings indicate a direct reduction in dengue incidence by 64.35% (95% CI: 63.50-66.71, p

    STATEMENT OF PROBLEM: Denture wearers are susceptible to diseases related to denture hygiene and are more prone to develop systemic disease because of poor understanding and awareness of the impact of edentulism on general health.

    PURPOSE: The purpose of this clinical study was to evaluate the effectiveness of traditional chairside practice and WhatsApp in improving patient knowledge of denture care and their awareness of the impact of edentulism on general health.

    MATERIAL AND METHODS: Sixty-two participants who attended the Polyclinic Kulliyyah of Dentistry, IIUM Kuantan in 2022 for removable prosthesis fabrication were recruited. The participants were randomized into 2 groups: control (traditional chairside) and intervention (WhatsApp) group. Video intervention was sent via WhatsApp to the participants. Pretreatment and posttreatment questionnaires were distributed from March to September 2022 to survey their sociodemographic data, knowledge of denture care, and awareness of the effect of edentulism on general health. Data were obtained and checked for normality using the Shapiro-Wilk test. Data were analyzed using the Mann-Whitney U and Wilcoxon-Paired Signed-Rank tests (α=.05).

    RESULTS: Eighty-two percent of participants favored WhatsApp as a tool for receiving information and used it daily (66.1%). The level of overall knowledge and awareness increased in groups after denture insertion instruction. Participants' knowledge of denture care (P=.001) and awareness of the effect of edentulism on general health (P=.001) improved significantly in the WhatsApp intervention group compared with the control group.

    CONCLUSIONS: WhatsApp can be used as an alternative tool for improving denture care knowledge among denture wearers; increased awareness was observed with WhatsApp compared with the traditional chairside approach.

    Exploring the relationship between discrimination perceptions and subjective well-being among college students with disabilities and the chain-mediated effects of psychological resilience and positive coping styles. Questionnaires were administered to 528 college students with disabilities using the Discrimination Perceptions Scale, Index of Well-Being Scale, Psychological Resilience Scale, and Simple Coping Styles Scale. SPSS 24.0 and Amos 26.0 were used to analyze chained mediation effects and construct structural equation modeling tests. ①Discrimination perception was significantly negatively correlated with subjective well-being (r = -0.294, p < 0.01), psychological resilience(r = -0.427, p < 0.01) and all 3 of its dimensions, and positive coping styles (r = -0.328, p <0.01); subjective well-being was significantly positively correlated with psychological resilience (r = 0.334, p < 0.01) and all 3 of its dimensions, and positive coping styles (r = 0.363, p<0.01); and positive coping styles was significantly positively correlated with psychological resilience(r = 0.433, p < 0.01) and all 3 of its dimensions.② The direct effect of discrimination perceptions on college students with disabilities was significant, and the mediating effect value was-0.191.③Psychological resilience and positive coping styles not only play a significant separate mediating role between discrimination perceptions and subjective well-being of college students with disabilities, with mediation effect values of -0.138 (49.11%) and - 0.087 (30.96%), respectively but also play a significant chain mediating role between discrimination perceptions and subjective well-being, with an effect value of -0.056 (19.93%). Discrimination perceptions can directly affect the subjective well-being of college students with disabilities, and can also indirectly affect the subjective well-being of college students with disabilities through the separate and chain-mediated effects of psychological resilience and positive coping styles.

    This review provides a comprehensive overview of ultrasonic wave propagation, with a primary focus on high-power ultrasound systems where cavitation bubbles are likely to occur. The review is structured to guide readers through the historical development of cavitation models, from early works such as the Rayleigh-Plesset equation to more advanced numerical approaches. It explores the dynamics of cavitation bubbles, their physical effects, and the key factors influencing bubble formation, growth, and collapse. In addition to bubble-induced cavitation, the review addresses nonlinear wave propagation in the absence of bubbles, highlighting phenomena such as harmonic generation and shock wave formation. A detailed discussion on the numerical modelling of ultrasonic systems follows, covering linear and nonlinear approaches, boundary conditions, and the challenges of accurately simulating cavitating systems. The review concludes with an analysis of recent developments, emerging trends, and future directions in computational modelling for ultrasonic applications. By presenting a structured overview of both the theoretical and practical aspects of ultrasonic wave propagation, this work aims to provide a foundation for future research and design improvements in sonochemical and acoustic systems.

    The UHPLC-MS/MS metabolomics approach was employed to profile and characterize multi-components in Halamphora sp. extracted with different solvents that contribute to quorum sensing inhibitory (QSI) activity. A total of 37 and 34 metabolites were tentatively identified from negative and positive ion modes, respectively. The metabolites have been assigned to various groups, including fatty acids, glycolipids, sterols, diazines, flavonoids, peptides, carotenoids, and pigments. Multivariate data analysis showed that the QSI activity in the acetone extract was due to tumonoic acid A, terpeptin derivatives, pheophorbide A, hydroxyhexadeca-1,5-dien-3-ynoxy]propane-1,2-diol, l-methionyl-l-tyrosine, stearidonic, hexadecadienoic, tricosenoic, palmitic, and linolenic acids. These metabolites were more concentrated and differed significantly in acetone extract compared to other extracts. Acetone extract displayed a cluster of nodulisporic acid and fucoxanthin through MS/MS-based molecular networking (MN) platform. The present study shows that the liquid chromatography mass spectrometry (LCMS)-based metabolomics and MN effectively identify QSI-active metabolites in Halamphora sp. extracts, which can be promoted as a natural antifoulant.
