    Cervical laminoforaminotomy (CLF) provides a safe and effective decompression procedure of nerve roots while maintaining cervical mobility and preserving stability. However, this unique technique requires appropriate patient selection and the technical ability of the surgeon to produce an excellent outcome. Furthermore, anterior cervical discectomy and fusion (ACDF) has been accepted as the "gold standard" procedure in managing cervical radiculopathy, despite posing the risk of anterior structure injuries and fusion. Here we report a case report of the surgical management of unilateral cervical radiculopathy using the CLF technique.

    The work was aimed at evaluating the adsorptive properties of waste newspaper (WN) activated carbons chemically produced using sodium salts for methylene blue (MB) and congo red (CR) removal. The activated carbons, designated as AC1, AC2, AC3 and AC4 were prepared through impregnation with NaH2PO4, Na2CO3, NaCl and NaOH, respectively and activation at 500 °C for 1 h. The activated carbons were characterized for surface chemistry, thermal stability, specific area, morphology and composition. The AC1 with a surface area of 917 m2/g exhibits a greater MB capacity of 651 mg/g. Meanwhile, a greater CR capacity was recorded by AC2 at 299 mg/g. The pseudo-second order model fitted well with the kinetic data, while the equilibrium data could be described by Langmuir model. The thermodynamic parameters, i.e.., positive ΔH°, negative ΔG° and positive ΔS° suggest that the adsorption of dyes is endothermic, spontaneous and feasible at high solution temperature. To conclude, WN is a potential cellulose source for producing activated carbon, while NaH2PO4 activation could be employed to convert WN into activated carbon for effective dye wastewater treatment.

    BACKGROUND: The COVID-19 pandemic has called for the rapid development and use of antiviral drugs to effectively control the disease. Nirmatrelvir/Ritonavir (Paxlovid), Molnupiravir, and Remdesivir have been pivotal in therapeutic approaches, although they raise concerns regarding adverse drug reactions (ADRs).

    OBJECTIVE: This study aimed to thoroughly assess the ADRs associated with these drugs by utilizing the Adverse Event Reporting System (FAERS) database of the Food and Drug Administration (FDA).

    METHODS: ADR reports for Paxlovid, Molnupiravir, and Remdesivir throughout the period of January 2022 to May 2023 were extracted and classified according to the severity, type of reaction, and demographic variables. Reporting Odds Ratios (RORs) with 95% confidence intervals were calculated to evaluate the relationship between antiviral medications and various ADRs.

    RESULTS: The study established notable correlations between Paxlovid and the recurrence of the disease (40.08%) and dysgeusia (16.29%). Molnupiravir was linked to gastrointestinal (16.73%) and skin reactions (9.47%), while Remdesivir had impairments in the liver (25.21%) and kidneys (13.34%). ADRs were more commonly observed in female patients treated with Paxlovid (57.95%) and Molnupiravir (49.40%), whereas Remdesivir ADRs were mostly reported in males (58.56%). Paxlovid and Remdesivir ADRs were frequently reported in adults between the ages of 18 and 64 (46.01% and 45.01%), while Molnupiravir ADRs were more common in older individuals aged 65 to 85 (40.38%).

    CONCLUSION: This thorough assessment emphasizes the importance of careful surveillance and control of ADRs linked to COVID-19 antiviral therapies. It is essential to customize treatments by considering specific patient histories, particularly for pre-existing diseases.

    As global concerns over climate change and sustainability grow, Environmental, Social, and Governance (ESG) factors have become critical in evaluating corporate practices. In China, the increasing adoption of ESG ratings by investors has highlighted discrepancies in these ratings, which may impact corporate risk. While extensive research exists on ESG performance, the effects of ESG rating disparities on corporate risk, particularly in Chinese enterprises, remain underexplored, especially the mediating role of financing constraints. Utilizing data from Chinese A-share listed companies from 2015 to 2022, this study examines the impact of Environmental, Social, and Governance (ESG) rating disparities on corporate risk, focusing on the mediating role of financing constraints. The findings indicate that discrepancies in ESG ratings significantly increase corporate risk, particularly in non-state-owned enterprises and heavily polluting industries, while having no significant impact on state-owned enterprises. Discrepancies in governance ratings exert the greatest impact on corporate risk, underscoring the critical role of corporate governance. Financing constraints further exacerbate the impact of rating discrepancies on corporate risk. These results provide new insights into enhancing the ESG rating system and mitigating corporate risk, offering a foundation for relevant policy-making.

    Heavy metal and microplastic pollutions are prevalent in freshwater ecosystems, with many freshwater bodies being contaminated by one or both of these pollutants. Recent studies reported extreme detections of Cd, Pb and Zn, high concentrations of Cr, Pb and Cu and microplastics acting as vectors of pollutants, including heavy metals. Mayflies can serve as bioindicators of heavy metal contamination in freshwater ecosystems because changes in their community structure, physiology, and behaviour can reflect and help predict the concentrations of metals in these environments. This review discusses the ecological alterations induced by tissue metal concentration in mayflies and other macroinvertebrates. As sensitive taxa to heavy metal contamination, mayflies can reflect the impacts of this pollution through their ethology and relationship to the substrate, highlighting issues such as eutrophication, alterations in community structure, inhibitory effects and sediment toxicity. Mayflies are also highly affected by microplastic exposure, which leads to ingestion, bioaccumulation, biomagnification, habitat and community alteration, behavioural changes, physiology alteration and toxicity. Mayflies bioindication metrics for assessing the impact of heavy metals and microplastics include the examination of community alteration, functional feeding behaviour, molecular structure, dietary and toxicity impacts, bioaccumulation and biomagnification and biomarkers. Current challenges for the utilization of mayflies as bioindicators include temporal variations in sensitivity, lack of universally recognised protocols and need for standardised protocols for microplastic analysis. Additionally, the applicability of mayflies as bioindicators may vary across different ecosystems, emphasising the need for selecting suitable indicators that align with the unique characteristics of the ecosystem.

    This research aims to investigate the antecedents of employee eco-initiatives toconcerning public service motivation, green work climate, employee environmental concern and supervisor environmental priority in Malaysia's healthcare sector. Based on the structural equation modeling (SEM) analysis with the help of SMART-PLS, it was found that public service motivation positively influences eco-initiatives in a direct and indirect manner through green work climate and employee environmental concern. The results stress the role of intrinsic motivation and organizational culture in changing people's behaviors sustainably. Healthcare organizations should encourage public service motivation, develop a supportive green work climate, and integrate environmental leadership to support sustainability. This research advances the field by proposing a holistic framework that captures both the organizational and personal antecedents of eco-initiatives in an environment where service demands are high.

    INTRODUCTION: Antimicrobial resistance is a global issue, with the World Health Organization identifying it as one of the greatest threats to public health, with an estimated 4.95 million deaths linked to bacterial AMR in 2019. Our study aimed to determine the prevalence of mortality among multidrug-resistant organism (MDRO)-infected patients in state hospitals and major specialist hospitals and to identify risk factors that could be associated with mortality outcomes.

    METHODS: This is a cross-sectional study performed at 28 hospitals under the Ministry of Health, Malaysia, involved in the National Surveillance of Multidrug-Resistant Organism, which surveys 6 MDROs (Acinetobacter baumanii, extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli, extended-spectrum beta-lactamase (ESBL)-producing Klebsiella pneumoniae, carbapenem-resistant Entrobacterales (CRE), methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE)).

    RESULTS: In terms of mortality, 9.6% (n = 951) of the patients died overall, whereas 90.4% (n = 8931) of the patients survived. Healthcare-acquired infection (HCAI) poses a high risk of mortality, with an adjusted odds ratio (aOR) of 2.91 (95% CI: 2.15-3.94). The presence of sterile specimens was significantly associated with increased mortality risk (aOR: 2.33, 95% CI: 2.02-2.68). Gram-negative bacteria had a greater mortality risk (aOR 1.63 95% CI: 1.37-1.93), whereas Acinetobacter baumanii had the highest prevalence of 30.7% (3033) among the 6 MDRO organisms isolated. Patients in medical-based departments had a greater mortality risk (aOR: 1.47, 95% CI: 1.22-1.75).

    CONCLUSION: HCAIs, Gram-negative bacteria, sterile specimens, medical-based departments and state hospitals have been shown to be associated with increased mortality risk in patients with MDRO infections. Improved surveillance and reporting mechanisms are necessary to better understand the burden of MDRO infections and guide research funding allocation.

    Environmental issues have resulted in the forming of sustainable materials, including natural fiber-reinforced PLA composites; nonetheless, this composite has low water resistance, resulting in poor composite performance. This research aims to investigate the impact of adding a small amount of graphene nanoplatelets (GNP) on the water absorption (WA) characteristic of bamboo/kenaf-reinforced PLA hybrid composites. The physical behavior and water resistance of the composites, as well as the mechanical performance and surface after 14 days of immersion, were comprehensively investigated. The study discovered that adding a small amount of GNP to composites increased their density, with the highest density of 1.6326 g/cm3 (1GBK), and altered the chemical composition's transmittance. Also, the inclusion of GNP increases the composite's crystallinity. Furthermore, the addition of GNP resulted in a decline in WA, with the lowest absorption being 4.95 % (1GBK), which is supported by the composites' increased contact angle. After 14 days of immersion, the GNP-filled composites were superior to the BK sample in terms of mechanical properties. When fibers absorb water, their surface degrades because the fibers are swelling, but GNP functions as a water barrier, preventing surface degradation due to inhibition of fiber swelling. This study highlights the potential for a straightforward and economical method to address the limited water resistance of bamboo/kenaf-reinforced PLA hybrid composites, a limitation that hinders their widespread use.

    Photobiomodulation (PBM) holds promise as a therapy modality, but its applicability is hindered by the lack of a quantitative model to predict the optimal dose for all forms of PBM. This study investigated the optimal PBM parameters for 532 nm green laser irradiation on SHSY5Y neuroblastoma cells, a commonly used in vitro model for neurodegenerative disease studies. A two-tailed, two sample t-test with equal variance was used to obtain the p-values and statistical significance. There are 3 sets of parameters showing significant ( p < 0 . 01 ) positive percentage biostimulation. 160 m W , 15 m i n produce a percentage biostimulation of ( 9 ± 10 ) % ; 180 m W , 5 m i n produce a percentage biostimulation of ( 19 ± 7 ) % ; and ( 200 m W , 5 m i n ) produce a percentage biostimulation of ( 9 ± 2 ) % . The highest significant ( p < 0 . 01 ) percentage bioinhibition observed is for 220 m W , 15 m i n (dose: 1008 J / c m 2 ) producing a bioinhibition of ( 54 ± 1 ) % . After identifying several parameters that produce noticeable photobiological effects (biostimulation and bioinhibition), this study compared the reaction of undifferentiated and differentiated SHSY5Y cells to laser irradiation and found that undifferentiated SHSY5Y cells shows greater photobiological effect from 532 nm laser irradiation ( p < 0 . 01 ) . This study demonstrated the differentiation-dependant photobiological effect of SHSY5Y in 532 nm laser PBM. This shows that considerations on the differentiation state of cells is important in PBM studies. The hypothesis of difference in intracellular reactive oxygen species (ROS) accumulation from laser irradiation can serve as a versatile explanation of the observed difference in photobiological effect. Further investigation into the role of ROS as a mediator of various photobiological effects from laser of different wavelengths is warranted.

    INTRODUCTION: Myopia is a refractive error where distant objects are not clearly seen and appear blurred. Goal of this study was to evaluate long-term effectiveness of Repeated Low-Level Red Light (RLRL) therapy for children with myopia, which primarily focused on Axial length (AL) and Spherical Equivalent Refraction (SER) as primary endpoints.

    METHODS: The research compared outcomes between RLRL treatment with Single Vision Spectacles (SVS) for childhood myopia management. We performed a systematic literature search in the PubMed, Embase and Cochrane databases using "Myopia" and " Repeated Low-Level Red Light ". Mean differences (MD) were estimated and the effects of therapies measured. Publication bias and heterogeneity analysis were carried out by Inverted Precision Effect Test-Precision Effect Estimate Standard Error (PET-PEESE) (and subsequent Search Sequential Analysis) and Tau test. Bayesian meta-analysis was performed using Jaffrey Amazing Statistical Package (JASP).

    RESULTS: This meta-analysis comprised 1,714 participants: 824 in RLRL and 890 in SVS group. Pooled effect size for AL reduction was 0.953 ± 0.294, (95% credible interval (CI) 0.775 to 0.980). Pooled effect size for SER reduction was 1.521 ± 0.662 (95% CI 0.102 to 2.736). PET-PEESE analysis revealed no significant publication bias (p-value 0.407). Random effects models were employed for presence of significant heterogeneity (3.9 and 5.7 for AL; 5.7 for SER), alongside degree of variation (0.828 & 1.665) for Tau (τ), which estimates the between-study variance.

    CONCLUSION: Long-term observations indicate that RLRL treatment significantly influences myopia management, leading to considerable reductions in both AL and SER. Additional research is essential to investigate potential long-term rebound effects.

    Objective  In nuclear medicine, quality control (QC) activities adhere to international standards, yet their complexity can pose challenges. Gamma camera manufacturers have introduced integrated QC software, offering instantaneous results. However, the agreement of these automated processes with established protocols remains uncertain. This study aims to clarify this uncertainty by comparatively analyzing uniformity from various software solutions for a dual-head gamma camera. Methods  The study utilized integrated QC analysis software and three free QC analysis tools (IAEA-NMQC Toolkit, NM Toolkit, and Fiji) for uniformity analyses. Following the National Electrical Manufacturers Association standards, NEMA Standards Publication NU 1-2018, the intrinsic uniformity test was performed on a GE Discovery NM/CT 670 Pro system. Ten uniformity QC images underwent analysis with both integrated QC software and alternative software. Data agreements were tested using the Blant-Altman regression-based analysis. Results  Significant differences were observed in integral and differential uniformities ( p

    This paper explores the electrical conductivity interphase of Ag/Epoxy composite using modified McLachlan theory and 3D finite element composite model through experimental verification. The model characteristic presents conductivity as a dynamic function influenced by particle content, particle electrical properties, electrical properties transition, and an exponent. This model was meticulously crafted, considering the intricate interplay between the polymer matrix and silver particles, the tunnelling distance between adjacent silver particles, and the interphase regions around particles. This model has proven its mettle through rigorous analysis of experimental results and the impact of various parameters on conductivity. The predictions have shown impressive alignment with the experimental data, highlighting the crucial roles played by the parameters in the conductivity of silver composites where the percolation threshold reached 6 vol % of filler loading. The experimental study demonstrated that the electrical conductivity was 3.84 × 10-1 S/cm for micro-sized particles and 1.32 × 10-2 S/cm for nano-sized particles. Notably, a large tunnelling distance drastically reduces conductivity, while higher and slighter surface energies of the polymer matrix and filler enhance conductivity. Furthermore, a thin interphase yields minimal conductivity, whereas a thick interphase and low waviness improve conductivity. The McLachlan-modified model falls slightly short in accuracy compared to the 3D finite element method models. Adjustments to the equations can enhance its alignment with experimental data.

    Gout is a disorder of purine metabolism described by the deposition of monosodium urate crystals with rare involvement in the head and neck. This is the first laryngeal gout case reported in Sabah, Malaysia. A 50-year-old gentleman with a long history of gouty arthritis presented with acute painless anterior neck swelling for two weeks. An ultrasound of the neck was done, which showed a midline neck mass with intralesional calcification of the cartilaginous component with suspicious erosion of the thyroid cartilage, which was suggestive of thyroid chondroma. However, a computed tomography (CT) scan of the neck showed the fluid collection in the subperichondrium of anterior thyroid cartilage with amorphous calcification, which raised suspicion of infected laryngeal gout. Based on histology and intraoperative findings, laryngeal gout was diagnosed as noted multiple tophy crystals. Microscopic examination confirmed birefringent crystalline deposits. The pathophysiology and management of this rare clinical entity are discussed. We reported this case due to its rarity as well as to increase awareness of laryngeal gout.

    Background/Objectives: Deep convolutional neural networks achieve strong histopathological image-classification performance but often require substantial computational resources. This study proposes DSR-VGG, a lightweight Depthwise Separable Residual VGG architecture for nasopharyngeal histopathological image classification. Methods: DSR-VGG comprises six Depthwise Separable Blocks with residual projection shortcuts, global average pooling, dropout regularization, and a classification layer. An inverse-frequency weighted random sampling strategy was used to address severe class imbalance. The primary evaluation used 88,002 nasopharyngeal histopathology patches from four classes: Normal, lymphoid hyperplasia, nasopharyngeal inflammation, and nasopharyngeal carcinoma. Training was repeated using three random seeds, with supplementary public datasets used to assess cross-dataset architectural robustness. Results: Across three runs, DSR-VGG achieved 99.764 ± 0.049% accuracy, 99.070 ± 0.365% balanced accuracy, and 99.219 ± 0.215% macro-F1. The model contained only 0.528 million parameters, required approximately 0.31 GFLOPs, and achieved 2.38 ms single-image inference latency under the stated GPU benchmarking conditions. Although several baseline architectures achieved marginally higher accuracy, DSR-VGG maintained competitive predictive performance with substantially lower computational complexity. Conclusions: DSR-VGG provides a favorable accuracy-complexity trade-off for histopathological patch classification. However, patient-/WSI-disjoint evaluation, independent multi-center validation, and whole-slide assessment remain necessary before clinical deployment.

    In thirst for economic growth, economies are engaged in anti-environmental activities that drive them towards climate change and CO2 emissions. Extensive CO2 emissions is a serious threat around the globe, especially in low-income countries that can prove detrimental to the environment. To prevent the worst impacts of carbon emission, it becomes necessary to explore the cause of CO2 emissions. In this vein, this work is conducted to evaluate the determinants of CO2 emissions in low-income countries spanning from 2000 to 2020. For estimation of models, panel data techniques are employed. The outcome of the study revealed that trade FDI, urbanization, and GDP per capita are the main contributing factors to environmental degradation. Trade openness has also impacted environmental degradation positively but insignificantly. In contrast, population density and domestic credit to private sector (DCPS) have negatively impacted low-income countries' carbon emissions. The study extended important policy implications to low-income countries' governments and environmental policymakers.

    Present climate change consists of global warming that is caused by the emission of greenhouse gases, generally carbon dioxide. The study examines the pollution haven, pollution halo, and environmental Kuznets curve for a number of Asian countries during the period of 1985 to 2020. Outcomes suggest that urbanization, gross domestic product per capita, energy consumption, and foreign direct investment inflow have positive effects, while gross domestic product square, foreign direct investment square, and tourism have negative effects on emissions of carbon dioxide. Furthermore, findings support the validity of the environmental Kuznets curve, pollution haven, and pollution halo hypothesis for the selected Asian countries. We also find robust results of rationality of the environmental Kuznets curve hypothesis for Pakistan, Bangladesh, India, China, Indonesia, Korea, Japan, Malaysia, Vietnam, and Singapore; of pollution haven hypothesis for Bangladesh, China, Indonesia, Japan, Pakistan, and Singapore; and of pollution halo hypothesis for Bangladesh, China, Indonesia, Japan, Pakistan, and Singapore.
