    INTRODUCTION: Evidence of the waning immunity of coronavirus disease 2019 (COVID-19) primary vaccination, and immune evasion by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants has led to the rollout of booster vaccination in many countries. Assessing the effectiveness of booster vaccination against severe COVID-19 outcomes is crucial during the transition to endemicity.

    METHODOLOGY: We conducted a population-based, matched case-control study in Malaysia to estimate the marginal vaccine effectiveness (mVE) of homologous and heterologous BNT162b2 and CoronaVac booster vaccination against COVID-19 related intensive care unit (ICU) admission and death in Delta-predominant and Omicron-predominant periods.

    RESULTS: Receipt of a booster vaccination - either homologous or heterologous for CoronaVac, and homologous for BNT162b2 - demonstrated mVE estimates of at least 70% against ICU admission and at least 80% against death, compared to BNT162b2 primary vaccination, in both periods. Overall, the mVE estimates were 10-20 percentage points lower in the Omicron-predominant period than in the Delta-predominant period.

    CONCLUSIONS: Our study reaffirms that the administration of booster vaccination increases protection against severe COVID-19 outcomes for BNT162b2 and CoronaVac primary vaccination recipients.

    INTRODUCTION: A prescribing cascade occurs when new medications are prescribed to address an adverse drug reaction (ADR) associated with the preceding use of a medication, which may be mistaken as the onset of a novel disease or condition. The aim of this study was to evaluate the perceptions of hospital pharmacists regarding roles in preventing and minimizing prescribing cascades.

    METHODOLOGY: A qualitative, semi-structured interview, followed by a quantitative, questionnaire-based study, was carried out at the Shifa International Hospital (SIH; Islamabad, Pakistan). Discharge summaries of patients aged ≥ 60 years were collected to assess the prevalence of polypharmacy at SIH.

    RESULTS: Discharge summaries of n = 350 patients were collected; 60.2% (n = 211) had comorbid conditions, and the co-occurrence of diabetes and hypertension were the most common. 37.8% (n = 132) were taking 8 or more medications. Eight (n = 8) hospital pharmacists participated in the qualitative study, and 4 major themes were identified in their perceptions regarding prescribing cascades. Fifty-two (n = 52) pharmacists were recruited in the quantitative phase. 86.5% (n = 45) of the participants reported long standing illness/chronic conditions; 67.3% (n = 35) noted the presence of comorbidities as a high risk, while 90.3% (n = 47) noted multiple prescribers, and 75.0% (n = 39) identified the ageing population as important risks factors for polypharmacy.

    CONCLUSIONS: The current research may inform the role and responsibilities of hospital pharmacists in outpatient and inpatient departments, and in interprofessional care teams, in preventing and minimizing prescribing cascades.

    Hot-pressed flaxseed oil is favored in Northwest China as cooking oil due to its flavor and oxidative stability. The mechanism of enhancing oxidation stability of hot-pressed flaxseed oil by neoformed Maillard reaction products (MRPs) remains mysterious. Maillard model reaction between phosphatidylethanolamine (PE) and reducing sugar of flaxseed, glucose (Glu)/fructose (Fru)/xylose (Xyl), was conducted to investigate the antioxidant characteristics of products. MRPs of PE-Xyl had a superior reactivity and anti-oxidative capabilities, which could improve the oxidative stability of flaxseed oil and inhibited the formation of aldehydes in the accelerated oxidation. Phosphatidylethanolamine-linked pyrrolecarbaldehyde (PLP) was the main antioxidant component in MRPs of Xyl-PE by MS and NMR analysis and verification of antioxidant activity. Furthermore, the results of quantum chemical calculation show that the antioxidant activity center of PLP is the pyrrole group. The findings of this study provide insights into the chemical basis underlying the improved oxidative stability of hot-pressed oils.

    INTRODUCTION: It can be challenging at times to clinically differentiate between acute seizure and acute stroke. This study aimed to compare the computed tomography perfusion (CTP) changes in patients presenting with acute seizures of different etiologies to those with acute cortical stroke.

    METHODS: We conducted a single-center cross-sectional case-control study on the CTP changes of 31 patients presenting with acute seizures of different etiologies, and compared them with 31 patients of acute cortical stroke patients (n = 31) as the control.

    RESULTS: 58.1% had increased time to peak (TTP) in the seizure group. None of the patients with acute stroke had reduced TTP compared to 25.8% in the seizure group. The majority of patients in the seizure group had normal to reduced relative cerebral blood flow (rCBF) (38.7% and 35.5%, respectively). 35.5% and 38.7% of the patients presenting with acute seizures had normal and reduced relative cerebral blood volume (rCBV), respectively. The association between the perfusion parameters and etiology of seizures, presence of underlying epilepsy, or presence of postictal neurological deficits was not statistically significant. The seizure group had cortical ribbon (51.6%), holo-hemispheric (32.3%), multi-lobar (9.7%), and normal (6.5%) CT perfusion patterns. In conclusion, our study shows that the majority of the patients of the acute seizure group had normal to hypoperfusion patterns. Seizure-related perfusion changes did not conform to expected vascular territories, and cortical ribbon pattern was found to be predominant in our study.

    SIGNIFICANCE: There is cerebral hypoperfusion or normal perfusion in most patients presenting with acute seizures. Seizure-related perfusion changes are not limited to arterial vascular territories.

    Accurate prediction of Parkinson's disease tremor (PDT) is crucial for developing assistive technologies; however, this is challenging due to the nonlinear, stochastic, and nonstationary characteristics of PDT, which substantially vary among patients and their activities. Moreover, most models only have one-step prediction capabilities, which causes delays in real-time applications. This paper proposes a self-attention deep temporal convolutional network (SADTCN) model for the real-time prediction of hand-arm PDT signals from different activities and joint angular motions. The SADTCN can capture both short- and long-term dependencies and complex temporal and spatial dynamics of PDT signals and hence, can effectively adapt to varying tremor characteristics. The performance of the proposed model is evaluated using experimental hand-arm PDT data. The results show that the SADTCN outperforms existing deep learning (DL) models by accurately predicting varying tremor amplitudes and frequencies multi-step ahead. Moreover, we performed spectrum analysis on the measured and predicted signal using the short-time Fourier transform (STFT) as a measure of potential active tremor control and found that SADTCN can accurately determine the transience of tremor amplitude in frequency and time. Finally, we run the Wilcoxon signed-rank statistical test and the results show a statistically significant improvement in the proposed model over the other DL models in all conditions. Therefore, the SADTCN can overcome the nonstationary, nonlinear, and stochastic nature of PDT to perform multi-step prediction with high accuracy, robustness, and generalizability in unseen testing data.

    INTRODUCTION: Obstructive sleep apnea (OSA) is a common sleep disorder that disrupts breathing during sleep. While continuous positive airway pressure therapy is the standard treatment, poor adherence has led to exploration of alternative treatments. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have been shown to reduce body weight and may help manage OSA. This systematic review and meta-analysis evaluated the efficacy and safety of GLP-1 RAs in individuals with OSA and elevated body weight who are without diabetes.

    METHODS: A systematic search was conducted in September 2024 across multiple databases. Randomized controlled trials (RCTs) evaluating GLP-1 RAs for OSA in adults with a body mass index (BMI) ≥30 kg/m2 were included. The primary outcomes were changes in the apnea-hypopnea index (AHI) and overall adverse events. Meta-analyses were performed using a random-effects model.

    RESULTS: Three RCTs were included in the analysis. Pooled results showed that GLP-1 RA treatment significantly reduced AHI compared to placebo, with a weighted mean difference (WMD) of -16.6 events per hour (95 % confidence interval [CI]: -27.9 to -5.3). However, GLP-1 RAs were associated with a higher frequency of adverse events, with an odds ratio (OR) of 1.62 (95 % CI: 1.16 to 2.24) compared to placebo.

    CONCLUSION: GLP-1 RAs effectively reduce OSA severity, offering a promising alternative for individuals with OSA and elevated body weight. However, the increased risk of side effects must be considered. Further long-term studies are needed to confirm the sustained benefits and safety of GLP-1 RAs in OSA management.

    OBJECTIVES: Hunter syndrome is among the costliest life-long genetic conditions associated with a substantial burden-of-illness and a significant impact on the health systems, families, and society. We estimated the cost-effectiveness of long-term enzyme replacement therapy with idursulfase versus the standard of care from a societal perspective using a streamlined modeling strategy in R.

    METHODS: A de novo 4-state partitioned survival model was developed to compare lifetime cost and outcomes of 2 care models operationalized in R. The disease progression was based on independent survival modeling of relevant Kaplan-Meier data. The healthcare and out-of-pocket costs were drawn from the local setting. The quality of life was measured using the EQ5D5L and the time trade-off valuation of health-state vignettes that match the states in the model. Probabilistic and deterministic sensitivity analyses were conducted to test the uncertainty around the model results.

    RESULTS: The lifetime incremental quality-adjusted life years were 4.1 years (95% CI, 2.37-5.68). Incremental costs were estimated to be $9.5 million (95% CI, 9.0 million-10.0 million), which primarily consists of drug costs (99%). The incremental costs per quality-adjusted life year were estimated to be approximately $2.4 million (95% CI, 1.7 million-3.8 million). Sensitivity analyses showed that the key drivers of incremental cost-effectiveness ratio were quality of life in the preprogression state and differential discounting approach, besides the acquisition cost of enzyme replacement therapy of idursulfase.

    CONCLUSIONS: The incremental cost-effectiveness ratios were beyond any conventionally used cost-effectiveness threshold in all cases. At the current price, there is a significant discrepancy between the therapy's funding decision and the cost-effectiveness assessment as a basis for guiding healthcare prioritization in Malaysia.

    We adapted a previous protocol to assess children's ability to spontaneously associate a novel cause with a novel emotional expression. An experimenter opened a series of boxes and generated an expression based on what was inside (the cause of the emotion). Participants (4- to 9-year-olds; N = 72) guessed what the experimenter saw from four possible objects linked to four expressions: stickers (happy), a broken balloon (sad), a spider (scared), and a novel object, pax (novel puffed cheeks expression). Children were then invited to open a series of boxes and generate expressions for the experimenter. Results suggest that children used a process of elimination to associate the novel pax object with the puffed cheeks expression. Some children also re-produced the puffed cheeks expression in a later task. As a final trial, when children were asked how people would feel when seeing the pax object, younger children tended to use positive labels and older children used negative labels. These results show that children are able to quickly associate novel facial expressions with precipitating events as early as 4 years of age, comparable to their performance in linking familiar expressions and objects.

    INTRODUCTION: There is an increasing prevalence of chronic kidney disease (CKD) in Malaysia; hence, identifying factors associated with the early stage of CKD is crucial for preventive measures. This study investigated the association between various factors and their interaction in a multi-ethnic Malaysian cohort.

    METHODS: A nested case-control analysis was conducted on 3,160 eligible participants with renal profile data from The Malaysian Cohort project. CKD status was determined by estimated glomerular filtration rate using the Chronic Kidney Disease Epidemiology Collaboration equation. Multiple logistic regression analysis using the likelihood ratio method was used to identify the factors and their interaction with CKD.

    RESULTS: This study suggested five factors associated with CKD: gender, ethnicity, physical activity, atherogenic plasma index (AIP), and systolic blood pressure. There was an interaction between AIP and gender, with increased odds of CKD among men with high AIP.

    CONCLUSIONS: As CKD is mainly asymptomatic until it is in the later stages, these five factors serve as valuable tools for predicting CKD and enhancing the identification of at-risk individuals, particularly among men with elevated AIP. Future studies should focus on using these factors, especially in preventing new CKD cases and their progression.

    BACKGROUNDS & AIMS: Citrin deficiency (CD) is an autosomal recessive urea cycle disorder caused by biallelic loss-of-function variants in the SLC25A13 gene, leading to life-threatening hyperammonemia and hypoglycemia. Variants in deep introns can cause genetic diseases by altering splicing and are often missed by current diagnostic tools. Splice-switching oligonucleotides (SSOs) can resolve certain intronic variants, but patients harboring such variants need to be identified. We present a lean workflow from molecular diagnostics to SSO development to resolve splice-altering variants in deep introns that is applicable to other genetic disorders.

    METHODS: A deep intronic-gene panel was designed to identify deep intronic variants. SSOs were then developed and validated in vitro using a minigene assay and induced hepatocytes, and target engagement was verified in vivo by hydrodynamic tail vein injection of minigenes and SSOs.

    RESULTS: With the deep intronic-gene panel and RNA analysis, we identified a novel SLC25A13 c.469-2922G>T variant that promotes the inclusion of a premature stop codon-containing pseudo-exon, SLC25A13-PE5, thereby causing CD. By a stepwise rational SSO design approach, we identified potent candidates inhibiting SLC25A13-PE5 at EC50 <2 nM in vitro. Upon conjugating the SSOs with GalNAc (N-acetylgalactosamine), they were validated to rescue normal protein expression and restore ureagenesis and ammonia clearance, key urea cycle functions, in patient-derived induced hepatocytes. In vivo on-target efficacy of the clinical GalNAc-SSO candidate, in the absence of acute toxicity and inflammation, was observed in a mouse model with exogenous hepatic minigene expression.

    CONCLUSIONS: Our data validates a platform to redefine the molecular diagnosis of urea cycle disorders and provides proof-of-concept for a precision therapy for patients with CD, for whom the only effective treatment is liver transplantation.

    IMPACT AND IMPLICATIONS: Deep intronic variants are common causes of genetic diseases that are commonly neglected. In this study, we demonstrate an integrated precision diagnostic and therapeutic approach for urea cycle disorders. Specifically, we focus on citrin deficiency, going from the discovery of a novel splice variant in the SLC25A13 gene with our novel deep intronic-gene panel for urea cycle disorders, to the development and in vivo validation of an efficacious splice-switching oligonucleotide candidate for the pathogenic splice variant. We envision the possibility of extrapolating this pipeline to the diagnosis and development of treatments for other rare genetic diseases.

    Transdiaphragmatic intercostal hernia is a rare condition that presents unique management challenges. We describe a 68-year-old morbidly obese male (BMI 40) with multiple comorbidities who underwent successful hybrid laparoscopic and open repair of a right transdiaphragmatic intercostal hernia. The hernia developed following blunt trauma 5 years earlier, which caused fractures of the right 4th-7th ribs. The patient presented with a swelling in the right flank region. CT imaging revealed a 5.9-cm diaphragmatic defect and a 10.6 × 11.9 cm intercostal defect containing small and large bowels, and omentum. Preoperative optimization included a very low-calorie diet and stabilization of diabetes, hypertension, and dyslipidemia. Surgery involved lateral decubitus positioning, customized laparoscopic port placement, an additional incision for defect closure, and laparoscopic onlay mesh placement. Recovery was uneventful, with discharge on postoperative Day 5 and no recurrence at 6 months. This case underscores the importance of meticulous preparation and hybrid techniques in managing complex hernias.

    Ischemic stroke remains a leading cause of morbidity and mortality worldwide, and early diagnosis is critical for improving clinical outcomes. This paper presents an optical design framework combining speckle contrast optical spectroscopy (SCOS) with multiwavelength reflectance spectroscopy to monitor subtle changes in cerebral blood flow during ischemic events. The research aims to enable precise tissue interrogation using high-resolution, low-scatter imaging. Key to the system's accuracy is a 1.55 μm small beam waist, a grating density of 1300 grooves/mm, and a 15.53 μm depth of focus. The calculated effective focal length of 8333.33 μm enhances the resolution to 4.07 μm, improving the detection of minor changes in tissue optical properties. We investigate the sensitivity of various near-infrared wavelengths (660, 785, 800, and 976 nm) to ischemic-induced changes, with particular emphasis on the 976 nm wavelength, which demonstrates superior tissue penetration and increased sensitivity to variations in blood perfusion and tissue density during ischemia. Optical markers such as spot-size widening, spatial intensity shifts, and central intensity decrease are identified as reliable indicators of ischemia. Our findings suggest that multiwavelength reflectance analysis, particularly in the near-infrared range, provides a practical, noninvasive approach for continuously monitoring ischemic strokes. This technique indicates potential for improving early diagnosis and real-time monitoring of cerebral perfusion, which allows for continuous, noninvasive monitoring of cerebral perfusion and management of ischemic strokes, improving patient outcomes and clinical decision-making.

    The fast growth of the Internet of Everything (IoE) has resulted in an exponential rise in network data, increasing the demand for distributed computing. Data collection and management with job scheduling using wireless sensor networks are considered essential requirements of the IoE environment; however, security issues over data scheduling on the online platform and energy consumption must be addressed. The Secure Edge Enabled Multi-Task Scheduling (SEE-MTS) model has been suggested to properly allocate jobs across machines while considering the availability of relevant data and copies. The proposed approach leverages edge computing to enhance the efficiency of IoE applications, addressing the growing need to manage the huge data generated by IoE devices. The system ensures user protection through dynamic updates, multi-key search generation, data encryption, and verification of search result accuracy. A MTS mechanism is employed to optimize energy usage, which allocates energy slots for various data processing tasks. Energy requirements are assessed to allocate tasks and manage queues, preventing node overloading and minimizing system disruptions. Additionally, reinforcement learning techniques are applied to reduce the overall task completion time using minimal data. Efficiency and security have been improved due to reduced energy, delay, reaction, and processing times. Results indicate that the SEE-MTS model achieves energy utilization of 4 J, a delay of 2s, a reaction time of 4s, energy efficiency at 89%, and a security level of 96%. With computation time at 6s, SEE-MTS offers improved efficiency and security, reducing energy, delay, reaction, and processing times, although real-world implementation may be limited due to the number of devices and incoming data.

    The rapid development of Blockchain Internet of Things (IoT) has intensified the need for efficient and secure cross-chain transmission across heterogeneous systems. However, traditional cross-chain methods, such as hash time-locked contracts and relay chains, focus primarily on security and correctness while neglecting performance optimization. This limitation is particularly pronounced in high-dynamic environments like port areas, where network congestion, high latency, and uneven resource utilization are prevalent challenges. To address these gaps, this study proposes a novel load-adaptive cross-chain control method tailored for Blockchain IoT systems in port areas. The proposed method integrates multi-feature joint learning with adaptive multi-channel joint bus control, enabling dynamic resource allocation and interference suppression for enhanced transmission efficiency. Furthermore, a distributed intelligent scheduling mechanism is introduced to improve scalability and stability under high-concurrency conditions by decentralizing task coordination across blockchain nodes. Additionally, federated learning is employed to optimize cross-chain communication while preserving data privacy, ensuring secure and collaborative optimization in multi-party environments. Extensive simulations validate the effectiveness of the proposed approach, demonstrating significant improvements in throughput, latency, and packet loss rate compared to traditional centralized methods. The results highlight the method's ability to balance dynamic network loads, minimize interference, and adapt to real-time conditions. This work bridges the gap between performance-oriented optimizations and privacy-preserving mechanisms, offering a scalable and secure solution for Blockchain IoT systems in complex and dynamic environments.

    Vector-borne infections impose a significant burden on global health systems and economies due to their widespread impact and the substantial resources required for prevention, control, and treatment efforts. In this work, we formulate a mathematical model for the transmission dynamics of a vector-borne infection with the effect of vaccination through the Atangana-Baleanu derivative. The solutions of the model are positive and bounded for positive initial values of the state variable. We presented the basic concept and theory of fractional calculus for the analysis of the model. We determine the threshold parameter, denoted by [Formula: see text], using the next-generation matrix method. The local asymptotic stability of the system at the disease-free equilibrium is analyzed. To establish the existence of solutions for the proposed model, we employ fixed-point theory. A numerical scheme is developed to visualize the system's dynamical behavior under varying input parameters. Numerical simulations are conducted to illustrate how these parameters influence the dynamics of the system. The results highlight key factors affecting the transmission and control of vector-borne diseases, offering insights into strategies for prevention and mitigation.

    BACKGROUND: Evidence shows that twin pregnancy is associated with increased adverse outcomes, including stillbirth. The present study aimed to investigate the global prevalence of stillbirth among fetuses resulting from twin pregnancies through a systematic review and meta-analysis.

    METHODS: To identify relevant studies, we adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We searched databases including PubMed, Web of Science, Google Scholar, Scopus, Embase, and Science Direct using keywords such as "stillbirth," "twin pregnancy," "fetus," and "prevalence" without applying any time constraints to the search. The quality of the articles was evaluated using the STROBE checklist. To ensure the reliability of our findings, we employed a random-effects model for analysis, and the heterogeneity of the studies was assessed using the I2 index. Data analysis was conducted using Version 2 of Comprehensive Meta-Analysis software.

    RESULTS: In a review of 10 studies with a sample size of 627,797 people, our meta-analysis revealed a global prevalence of stillbirth among fetuses resulting from twin pregnancies, reported to be 1.4% (95% CI 0.9-2.1). Our study also showed that with increasing sample size and years of study, the global prevalence of stillbirth among fetuses resulting from twin pregnancies decreased (p

    Chronic wound healing is associated with prolonged elevated inflammation and high levels of oxidative stress leading to cell death. The majority of wounds are colonized with antibiotic-resistant bacterial biofilms such as Pseudomonas aeruginosa and Staphylococcus aureus. An ideal wound treatment should include agents with antioxidant, anti-inflammatory, and antibiofilm behavior. Therefore, in this study, a combination of curcumin nanoparticle (Cur-NP) and silver nanoparticle (AgNP) (Cur-NP/AgNP) loaded PVA hydrogel was used to inhibit the bacterial attachment and subsequent biofilm formation of P. aeruginosa and S. aureus. Cur was known for its antioxidant and anti-inflammatory effect while being non-toxic to cells. Meanwhile, AgNP demonstrated superior anti-bacterial and antibiofilm activities against both P. aeruginosa and S. aureus. Cur-NP/AgNP loaded PVA hydrogels completely inhibited the bacterial attachment and biofilm formation, possibly due to synergistic effect of Cur-NPs and AgNPs in killing the bacterial cells. It should be highlighted that no surviving bacterial cells were noted for Cur-NP/AgNP loaded hydrogels. On the other hand, AgNPs or Cur-NPs alone loaded hydrogels were unable to achieve complete inhibition of biofilm formation, even though significant reduction in the biofilm mass was noted compared with control samples. Cur-NP and AgNP exerted oxidative-stress induced cell death in HaCaT cells via mitochondrial dysfunction, mitochondrial membrane potential (MMP) reduction, adenosine triphosphate inhibition, and increased cytochrome C release. The toxicity of formulation followed the decreasing trend: Cur-NP/AgNP

    BACKGROUND: The impact of mothers' socioeconomic status (SES) on late adolescents' emotional stability, as well as the mechanisms underlying this relationship, remain poorly understood in China. Additionally, the mechanisms by which SES impacts emotional stability may need investigated separately for the male and female adolescents.

    METHOD: This study conducted a snowball sampling and invited undergraduates to complete a survey via online. A sample of 445 Chinese undergraduate students (229 males, age range of 18-25 years) completed questionnaires concerning their mothers' monthly income and educational levels, emotional stability, and maternal parenting styles. Independent samples t-test, correlation analyses and regression analyses were performed.

    RESULTS: The findings suggested the levels of emotional stability in female students were significantly lower than those of male students. Mothers' SES was related to late adolescents' emotional stability significantly. Moreover, maternal parenting styles (emotional warmth, punishment, overprotection, and rejection) significantly mediated the relationship between mothers' SES and late adolescents' emotional stability. Additionally, the particular features of these relationships varied according to the sex of the late adolescents. For the male students, maternal parenting styles could not significantly serve as mediating roles. For the female adolescents, the effect of maternal SES on emotional stability was partially mediated by four separate pathways: (1) maternal emotional warmth, (2) maternal punishment, (3) maternal overprotection, and (4) maternal rejection. These findings provide crucial practical implications for identification, prevention, and intervention efforts in late adolescents' emotional stability across sex.

    CONCLUSION: This study sheds light on the relationship between mothers' SES and late adolescents' emotional stability, and the indirect effects of maternal emotional warmth, punishment, overprotection, and rejection serving as mediating roles. Maternal parenting styles had a higher effect on the emotional stability in female adolescents than male adolescents. This also provides crucial practical implications for identifying, preventing, and intervening in late adolescent emotional stability, which may differ between female and male adolescents.
