    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.

    The idea of linear Diophantine fuzzy sets (LDFs) is a novel tool for analysis, soft computing, and optimization. Recently, the concept of a linear Diophantine fuzzy graph has been proposed in 2022. The aim of this research is to extend topological numbers to LDFSs. A real value assigned to a particular graph is known as a topological graph theoretic parameter. We extend the bound of the crisp graph toward the linear Diophantine fuzzy graph (LDFG), including the edge and vertex deletion operations via LDFG theoretic parameters. We also investigate the interesting bound of the LDFGs via LDFG theoretic parameters. Finally, for decision-making problems, we developed an algorithm by exploiting the relationship between LDFG theoretic parameters and LDFSs. Based on the established approach, we discussed a numerical example of an application of a medical diagnosis using the linear Diophantine fuzzy Sombor graph parameter and the first, fifth, and sixth versions of the linear Diophantine fuzzy Sombor graph parameters.

    BACKGROUND: Diabetic kidney disease populations are categorized as high risk for fasting in Ramadan due to various potential fasting-related complications. Insulin analogues are recommended to be used in place of human insulin during fasting, as they carry a lower risk of hypoglycaemia and stable glycaemic variability. A paucity of data exits on the safety and efficacy of different basal insulin types during fasting for this population. This study aims to evaluate the safety and efficacy of three basal insulin among patients with Type 2 Diabetes Mellitus and concomitant mild to moderate chronic kidney disease who are keen to fast during Ramadan.

    MATERIALS AND METHODS: A single-centered, prospective observational study was conducted among 46 patients with type 2 diabetes mellitus and concomitant chronic kidney disease stage 2 and 3 who were on three different types of basal insulin (Glargine U-100, Levemir, and Insulatard), fasted in Ramadan 2022. All variables were listed as median (IQR). Hypoglycaemia events and glycemic variability obtained from Freestyle Libre continuous glucose monitoring were compared between insulin groups. Changes in glycated haemoglobin, fasting plasma glucose, renal profile, body weight, body mass index, and waist circumference pre and post-Ramadan were evaluated.

    RESULTS: The glycaemic variability was found highest in Insulatard with a median (IQR) of 37.2(33)% versus Levemir 34.4(32.4)% versus Glargine U-100 36.8(30.6)%, p = NS. Levemir had reported the lowest median time of below range of 2.5(13)% followed by Glargine 4(25)% and Insulatard 5(8)%; p = NS. The findings of this study indicated that glycated haemoglobin, fasting plasma glucose, renal profile, body weight, body mass index, and waist circumference did not alter statistically between the three groups post-Ramadan. Individually, Insulatard showed a significant reduction in weight and waist circumference (0.9kg, p = 0.026; 0.44 cm, p = 0.008) while Levemir showed a reduction in waist circumference (0.75cm, p = 0.019).

    CONCLUSION: This study revealed that Insulatard, Levemir, and Glargine demonstrated similar levels of safety and efficacy among those with diabetic kidney disease who observed fasting during Ramadan.

    BACKGROUND: International guidelines recommend contrasting initial treatment strategies for functional dyspepsia (FD).

    AIMS: To evaluate the efficacy and safety of treatment according to subtypes, compared with empirical proton pump inhibitor (PPI), in the initial treatment of FD.

    METHODS: We performed a single-blinded, randomised controlled trial of adults with FD. In the intervention group (treatment according to subtype), patients were categorised into epigastric pain syndrome (treatment esomeprazole); postprandial distress syndrome (PDS; treatment itopride) and overlap (treatment itopride, maintain, add/or switch to esomeprazole at week 4). The control group received esomeprazole only. The primary efficacy outcome was the assessment of global symptom improvement (primary end point: best two points from the 7-point Likert scale) over 8 weeks. Secondary outcomes included assessment of the change in nine individual upper gastrointestinal symptoms, quality of life (Short-Form Nepean Dyspepsia Index) and adverse events.

    RESULTS: We randomised 180 patients (median age: 50; 68.7% female 56.7% PDS) 1:1 into intervention and control arms. The percentage of patients achieving the primary efficacy outcome were 74.4% and 72.2%, respectively (p = 0.74). The improvement of individual symptoms in both groups were similar. The SF-NDI improved after treatment in both groups (p

    Despite growing international criticism of actions and efforts to change sexual orientation and gender identity, such efforts remain prevalent in Malaysia. Using data from a nationwide community-based survey, this study examined the prevalence of these efforts amongst LGBT+ adults and the association between exposure to them and mental health outcomes. Participants (n = 521) completed an online survey assessing exposure to efforts to change their sexual orientation and/or gender identity, internalised LGBT-phobia, negative future expectations, and several mental health variables. Just under sixty-four percent (n = 333) of participants reported having experienced change efforts, with the most common perpetrators being family members, friends and religious organisations or people. Recent (past year) and past exposure to change efforts (over one year ago) were each associated with significantly higher odds of suicidal ideation, non-suicidal self-injury, and suicide attempts. Participants with recent exposure to change efforts also reported elevated internalised LGBT-phobia and negative future expectations compared to those who lacked such experience. A content analysis of participants' open-ended responses documented the perceived impact of change efforts on proximal stressors and mental health and wellbeing. Recommendations are made for national authorities and healthcare bodies to ban efforts to change sexual orientation and gender identity in Malaysia.

    Soft tissue sarcomas are malignant tumors characterized by heterogeneity and are associated with a high mortality rate. Histopathological grading is considered a pivotal factor in prognostication and treatment planning. While core needle biopsy exhibits high accuracy in determining tumor histology, it fails in some cases, potentially misclassifying high-grade tumors as low-grade. Magnetic resonance imaging (MRI) has been evaluated as an adjunctive tool for predicting histopathological tumor grade. This systematic review and meta-analysis evaluated MRI features capable of distinguishing high-grade from low-grade tumors in patients with soft tissue sarcoma. A literature search was carried out in PubMed, Embase, and Cochrane Central in May 2024. The following features were evaluated for both low-grade and high-grade tumors: tumor size, heterogeneity on T2, presence of necrotic areas, margin definition on T1, and post-contrast peritumoral enhancement. Statistical analysis was conducted using the OpenMeta[Analyst] software (Providence, RI: Brown University), applying random effects models for pooled analyses with a 95% confidence interval (CI) based on the inverse variance method. A total of four studies, involving 343 patients categorized by tumor grade (high-grade or low-grade), who underwent MRI, were included in the analysis. The meta-analysis found similar incidences of tumor sizes less than 5 cm in both high-grade and low-grade tumors (22.7%; 95% CI: 10.3-25% vs. 27%; 95% CI: 2.7-51.2%) and tumor sizes greater than 5 cm (71.3%; 95% CI: 64-78.6% vs. 52%; 95% CI: 23.6-80.5%). High-grade tumors showed a higher incidence of post-contrast peritumoral enhancement compared to low-grade tumors (66%; 95% CI: 43-89% vs. 26%; 95% CI: 4.6-47.4%) as well as heterogeneity on T2 greater than 50% (72.4%; 95% CI: 49.3-95.4% vs. 25.4%; 95% CI: 5.2-56%). Additionally, high-grade tumors had a lower incidence of the absence of necrotic signal compared to low-grade tumors (28.8%; 95% CI: 8.5-49.1% vs. 68%; 95% CI: 57.5-78.6%). Our findings suggest that post-contrast peritumoral enhancement, presence of necrotic areas, and heterogeneity on T2 greater than 50% are MRI features associated with high-grade tumors in soft tissue sarcoma. Tumor size, however, does not appear to be a reliable indicator for differentiating tumor grade.

    Ischemic stroke is the second leading cause of mortality and morbidity worldwide. Due to the urgency of implementing immediate therapy, acute stroke necessitates prompt diagnosis. The current gold standards for vascular imaging in stroke include computed tomography angiography (CTA), digital subtraction angiography (DSA) and magnetic resonance angiography (MRA). However, the contrast agents used in these methods can be costly and pose risks for patients with renal impairment or allergies. The aim of this paper is to provide a comprehensive overview of current MRI techniques and sequences for evaluating ischemic stroke, emphasizing the importance of non-contrast options and their clinical implications for radiologists in the diagnosis and management of ischemic stroke. Standard MRI sequences-such as T1-weighted imaging (T1WI), T2-weighted imaging (T2WI), fluid-attenuated inversion recovery (FLAIR), diffusion-weighted imaging (DWI), DWI-FLAIR mismatch, and apparent diffusion coefficient (ADC)-are essential for determining infarct location, volume, and age. Additionally, incorporating susceptibility-weighted imaging (SWI) sequence aids in identifying signs of hemorrhagic transformation within the infarcted region. Advanced techniques like arterial spin labeling (ASL) can serve as a non-contrast alternative for mapping cerebral blood flow (CBF) and allowing for comparison between infarcted and healthy brain areas. Adding ASL to the routine sequence allows ASL-DWI mismatch analysis that is useful for quantifying salvageable tissue volume and facilitate timely recanalization, while time-of-flight (TOF) MRA and magnetic resonance venography (MRV) help assess venous thrombosis, stenosis, or arterial occlusions. Finally, MR spectroscopy can provide insights into critical brain metabolites, including N-acetylaspartate (NAA), and lactate (Lac) to determine patient prognosis. Current MRI technology provides a myriad of sequence options for the comprehensive evaluation of ischemic stroke without the need for contrast material. A thorough understanding of the advantages and limitations of each sequence is crucial for its optimal implementation in diagnosis and treatment.

    Background: Despite the large number of studies that have been done in this area, there is still a gap in the literature when it comes to comparing the orthodontic tooth movement (OTM) efficacy of Invisalign and fixed orthodontic appliances. The primary objectives of this study were to evaluate and compare the efficacy of Invisalign and fixed orthodontic appliances in terms of the amount and rate of OTM. Specifically, the study aimed to determine if there was a statistically significant difference between these two treatment modalities in achieving OTM and to assess whether treatment duration differs significantly between Invisalign and traditional fixed appliances. This investigation seeks to address the existing gaps in the literature by providing a clear comparison based on recent empirical evidence, thereby contributing to more informed treatment decisions in orthodontic practices. Methodology: Relevant MeSH keywords and Boolean operators were selected by a team of reviewers to search several online databases for papers that were in accordance with the objectives of our review. Results: At the end of the search protocol, 10 studies were deemed to be eligible for inclusion in the review. The pooled analysis revealed a statistically significant reduction in treatment time for patients using Invisalign compared to those with fixed appliances, with a total OR of 0.61 [95% CI 0.43, 0.85]. No significant heterogeneity was detected (I 2 = 0%), and the test for overall effect was significant (Z = 2.86, p=0.004). Furthermore, a nonsignificant trend favoring Invisalign was shown, with an odds ratio of 1.43 and a confidence interval that included 1 (0.97, 2.10). The p value was 0.07, and there was negligible heterogeneity among studies, as indicated by an I 2 of 0%. Conclusion: Based on the findings from the selected studies, it can be concluded that Invisalign and fixed orthodontic appliances have similar overall efficacy in eliciting OTM. However, Invisalign treatment requires significantly less time to complete than fixed orthodontic appliances. Despite these observations, further studies are required to explore the long-term stability of OTM achieved with Invisalign and fixed orthodontic appliances. Registration and Protocol: Registration was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards (CRD42023405593). The research protocol was created to meet the goals and was properly filed with PROSPERO; however, it has not been prospectively registered.

    A pulled elbow is a common type of injury in children aged one to four years, where the forearm is pulled in an extended pronated position. There are a few cases of pulled elbow reported in children under one year old. We experienced an atypical pulled elbow case in a six-month-old girl after her mother rolled her from a right lateral position to a supine position, leaving her arm trapped behind her back. The pulled elbow was suspected based on the classical presentation of pain over the elbow, a less mobilized limb, and a pronated arm position as well as the exclusion of fracture from a plain radiograph. A high index of suspicion of pulled elbow should be kept in infants, despite their age presentation and the absence of an obvious elbow-pulling mechanism.

    The sun generates light and heat for life on Earth to flourish. However, during the late Hadean-early Archean epoch on Earth, the "faint young sun" (FYS) was less luminous, influencing prebiotic chemistry and, by extension, the origins of life (OoL). However, higher levels of ultraviolet (UV) radiation from the FYS, especially UV-C, due to the lack of an ozone layer, would likely have impacted the assembly, stability, persistence, and functions of prebiotic cellular precursors, i.e., protocells. Consequently, it is essential to study how such UV-C radiation would have affected the synthesis and stability of prebiotically relevant molecules and protocells to better understand the plausibility of the OoL during the FYS period. In this letter, we introduce unanswered questions surrounding the structure and stability of protocells under UV-C radiation. Such a perspective may be vital to exoplanetary systems orbiting other stars, enhancing our understanding of life's potential beyond our solar system.
