    Odontocetes are globally distributed and are foundational to the structure and function of marine food webs, and hence bycatch impacts from gillnet fishing need to be considered in the context of their conservation and population viability. Currently, global gillnet bycatch numbers are unknown yet are estimated to be the greatest in Asia, East Africa, and the west coasts of North and South America. Here we provide the first global meta-analyses of small- and large-scale gillnet bycatch estimates of odontocetes during 1990-2020, compiling population size, estimated gillnet bycatch, and conservation status in support of geographical and species-specific risk estimates. We estimate that annual gillnet bycatch is ∼50,000 from 1990 to 2020, and, combined with overfishing, pollution, and noise, it has been shown to be a serious threat to these long-lived and slow-reproducing species with heavy offspring investment. The global gillnet bycatch of odontocetes is a difficult challenge to address and mitigate and requires improved species and regional-based management strategies including collaborations between fishers, fisheries managers, marine mammal experts, and marine spatial planners. This has been worked on for decades, yet more attention is needed for successful management of odontocete gillnet bycatch to ensure their sustainable future in the Anthropocene Ocean, in accordance with local subsistence dynamics and the relevant United Nations (UN) sustainable development goals.

    BACKGROUND: Truancy is correlated with variety of unfavorable outcomes that can negatively impact adolescents' development and well-being. We investigated the prevalence of truancy and its associated factors among school-going adolescents in Malaysia in 2022.

    METHODS: We used secondary data from the National Health and Morbidity Survey 2022. It is a cross-sectional study with a multistage stratified cluster sampling study design including 32,290 students aged 13 to 17 years old. It utilized the self-administered questionnaire from the validated Malaysian Global School-based Health Survey (GSHS). The associations between the truancy and its associated factors were examined using multivariate logistic regression, a complex sample analysis with sampling weightage.

    RESULTS: The prevalence of truancy was 25.6% (95% CI=24.25, 26.98). In the multivariate analysis, truancy was significantly associated with older age groups (P<0.001), adolescents with separated/ divorced/ widowed parents (P<0.001), those with current any tobacco product use (P<0.001), those with ever drug use (P<0.001), those who have been physically attacked (P<0.001) and being bullied (P<0.001).

    CONCLUSION: Gender, age, parent marital status, and adolescents with risk behavior were associated with truancy. This information may provide evidence for the implementation of effective prevention and intervention strategies to reduce truancy among these school-going adolescents.

    BACKGROUND: Community Health Volunteers (CHVs) are crucial in achieving universal health coverage and vital in public health activities, including the COMBI (Communication for Behavioral Impact) approach for dengue prevention and control and assessing the performance of COMBI CHVs are essential in evaluating the program effectiveness. We aimed to measure the level of performance and determine predictors of high-performance among COMBI CHVs in Kuala Lumpur and Putrajaya.

    METHODS: A cross-sectional study was conducted in 2023 among 285 COMBI CHVs from 5 health operational zones in Kuala Lumpur and Putrajaya. The CHVs were stratified proportionately, with 45.5% of respondents randomly selected from each stratum based on their zones. Self-administered questionnaires assessed their performance level and associated factors, including training, supervision, knowledge, motivation, and job satisfaction. Chi-square and Multiple Logistic Regression tests were used to determine the factors and predictors of high-performance COMBI CHVs.

    RESULTS: The prevalence of high-performance COMBI CHVs was 59.3%, significantly associated with training factors (experience, duration, and adequacy of training), supervision factors (being supervised, supervision frequency, and encouragement from supervision), motivation and job satisfaction level. As for significant predictors, having at least one day of training (AOR=14.557), being supervised by medical personnel (AOR=4.997), having a high motivation level (AOR=5.538) and having a high job satisfaction level (AOR=4.562) were more likely to have a high-performance level.

    CONCLUSION: Training duration, supervisor background, motivation and job satisfaction can contribute to high-performance levels among COMBI CHVs, which can applied in evidence-based policies and strategies for performance improvement and more effective community healthcare delivery.

    This study explores the causes of curiosity-driven impulse buying in blind boxes using the Stimulus-Organism-Response (S-O-R) model and adaptation level theory. It examines how store environment and product factors contribute to customer curiosity, incorporating price consciousness into the overall framework. Insights from an online survey of 306 Chinese respondents indicate that environmental factors and specific product characteristics positively influence consumer curiosity, while price consciousness has a negative moderate effect. The findings also show that customer curiosity stimulates impulse buying behavior and mediates the relationship between store atmosphere, surprise, and perceived novelty. This study identifies both objective and subjective factors behind blind box impulse buying and offers relevant suggestions for governments and consumers on managing impulse buying.

    BACKGROUND AND AIM: Distinguishing dengue fever (DF) from other viral infections solely based on common presentations poses a challenge. Therefore, there is a pressing need for additional diagnostic parameters that are reliable, swift, and cost-effective. This study aims to provide novel insights into the diagnostic value of hematological parameters, particularly mean monocyte volume (MMV), in predicting DF in Kelantan, Malaysia.

    METHODOLOGY: This cross-sectional study enrolled 162 patients with suspected DF symptoms. The diagnosis was confirmed through dengue immunoglobulin M (IgM) capture enzyme-linked immunosorbent assay (ELISA) or Dengue Early ELISA for nonstructural protein 1 (NS1) antigen detection. Hematological parameters were measured using the Coulter DxH 800 hematology analyzer (Beckman Coulter, Brea, CA), and the statistical analysis was performed using SPSS version 22 (IBM Corp., Armonk, NY).

    RESULTS: A total of 108 patients tested positive for DF, while 54 tested negative. We observed significant differences in WBC count, platelet count, and monocyte percentage between patients with DF and non-DF, while no significant correlation was noted for MMV. Subsequent statistical analysis, including receiver operating characteristic (ROC) curve analysis, revealed that monocyte percentage exhibited the largest area under the curve (0.715), indicating its potential as moderate discriminative power in diagnosing DF.

    CONCLUSIONS: Our study findings indicate that monocyte percentage and MMV outcomes are insufficient for predicting DF, suggesting potential areas for further research.

    Granulomatosis with polyangiitis (GPA) is a subtype of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) that commonly requires aggressive immunosuppression to achieve remission. We present a case of a young Malay lady with recurrent episodes of ANCA-positive nodular anterior scleritis who responded poorly to topical and systemic corticosteroids and relapsed while on methotrexate. A year later, she had epistaxis, and a sino-nasal biopsy confirmed granulomatous vasculitis. While receiving cyclophosphamide, she developed proptosis with optic neuropathy, which resolved with intravenous methylprednisolone. She eventually required rituximab as she was still having relapses on other immunosuppressants. Adequate and targeted treatment with immunomodulators is crucial to achieving disease remission in GPA.

    BACKGROUND: The opioid crisis continues to be a public health concern worldwide due to the high rates of misuse and associated mortality. Opioid dispensing competencies are critical for pharmacy graduates to promote the rational use of opioids.

    PURPOSE: To evaluate the opioids dispensing competencies among the final year Pharm-D students in Punjab, Pakistan.

    DESIGN: A multicenter cross-sectional study.

    METHODS: A validated survey was used to evaluate 11 competencies related to opioid use from the final year Pharm-D students from diversely located accredited institutes. On a summative scale, correct response to each survey item was worth a score/point. Descriptive statistics was used for categorical variables while independent t-test computed group differences.

    RESULTS: A total of n = 661 final year Pharm-D students from 28 institutes (8 public and 20 private) completed the survey with an overall response rate of 78.5%. Comparatively, the students who had either completed a community or hospital internship, or studying in the educational institutions located in the provincial capital demonstrated a significant higher competency score. There was no significant difference in the overall mean competency scores based on gender or system of assessment used in the Pharm-D degree programs. Among eleven opioid competencies, students received the lowest scores for "opioid overdose management", "opioid monitoring" and "therapeutic uses of opioids".

    CONCLUSION: Pharm-D students in Pakistan require additional training and skills on many of the opioids related competencies to ensure patient's safety in healthcare settings. There is a need to revise the curriculum and teaching methodologies to improve the competencies of Pharm-D students in opioid dispensing.

    In this study, we present the synthesis of a silver nanocomposite by utilizing a β-cyclodextrin (βCD) polymer anchored onto the surface of magnetic g-C3N4 (referred to as g-C3N4-Fe3O4/βCD-Ag). The structure and composition of the g-C3N4-Fe3O4/βCD-Ag nanocomposite were thoroughly characterized using various techniques, including FT-IR, FE-SEM-EDS, TEM, TGA, XRD, ICP, and VSM. This catalytic system exhibited excellent selectivity in reducing nitro groups, even in the presence of other reactive functional groups, resulting in high yields ranging from 85 to 98%. Moreover, the organometallic nanocatalyst could be easily recovered from the solution using an external magnet and demonstrated consistent catalytic activity over six consecutive runs with a slight decrease.

    Alzheimer's disease (AD) is a neurodegenerative ailment that is becoming increasingly common, making it a major worldwide health concern. Effective care depends on an early and correct diagnosis, but traditional diagnostic techniques are frequently constrained by subjectivity and expensive costs. This study proposes a novel Vision Transformer-equipped Convolutional Neural Networks (VECNN) that uses three-dimensional magnetic resonance imaging to improve diagnosis accuracy. Utilizing the Alzheimer's Disease Neuroimaging Initiative (ADNI) dataset, which comprised 2,248 3D MRI images and diverse patient demographics, the proposed model achieved an accuracy of 92.14%, a precision of 86.84%, a sensitivity of 93.27%, and a specificity of 89.95% in distinguishing between AD, healthy controls (HC), and moderate cognitive impairment (MCI). The findings suggest that VECNN can be a valuable tool in clinical settings, providing a non-invasive, cost-effective, and objective diagnostic technique. This research opens the door for future advancements in early diagnosis and personalized therapy for Alzheimer's Disease.

    BACKGROUND: The interplay of OGG1, 8-Oxoguanine, and oxidative stress triggers the exaggerated release of cytokines during malaria, which worsens the outcome of the disease. We aimed to investigate the involvement of OGG1 in malaria and assess the effect of modulating its activity on the cytokine environment and anemia during P. berghei malaria in mice.

    METHODS: Plasmodium berghei ANKA infection in ICR mice was used as a malaria model. OGG1 concentration and oxidative stress levels in P. berghei-infected mice and their control counterparts were assessed during malaria using enzyme-linked immunosorbent assay. OGG1 activity in malaria mice was modulated using treatment with TH5487 and O8-OGG1 inhibitors. The effects of modulating OGG1 activity using OGG1 inhibitors on cytokine release and anemia during P. berghei malaria infection were assessed by cytometric bead array and measurement of total normal red blood cell count respectively.

    RESULTS: The plasma OGG1 level was significantly upregulated and positively correlated with parasitemia during P. berghei malaria in mice. Modulation of OGG1 ameliorated malaria severity by improving the total normal RBC count in TH5487 and O8-treated mice. Modulation of OGG1 with TH5487 caused significant reductions in serum levels of TNF-α, IFN-γ, IL-6, and IL-10. Similarly, OGG1 modulation activity using an O8-OGG1 inhibitor caused a significant reduction in serum levels of TNF-α, IL-2, IL-6, and IL-10.

    CONCLUSION: The findings indicate the involvement of OGG1 in the P. berghei malaria infection. OGG1 inhibition by TH5487 and O8-OGG1 inhibitors suppressed excessive cytokine release, and this may represent a novel therapeutic strategy for ameliorating the severity of malaria infection.

    Wheelchair propulsion is a fundamental skill in wheelchair sports, particularly in wheelchair tennis. To achieve optimal mobility during wheelchair athletic performance, it is essential to consider propulsion techniques. This study examines the effect of push frequency and stroke duration on wheelchair maneuverability, measured by velocity during propulsion, among wheelchair tennis athletes. The athletes (N = 9; 5 elite and 4 novice) performed three tests; namely the comfortable speed propulsion test, sprint test and round-trip test; with and without holding their racquet, over their hard court. Results revealed that push frequency had positive correlation with propulsion velocity (r = 0.840, p

    Food allergies are a global health problem that continues to grow annually, with a prevalence of more than 10%. Shrimp allergy is the most common and life-threatening allergy. There is no cure for food allergies, but shrimp allergen extract (SAE) offers promise as a treatment through allergen-specific immunotherapy (AIT). However, whether SAE induces immunological tolerance in seafood allergies remains to be established. This study aimed to determine the effectiveness of SAE in inducing immunological tolerance in a gastro-food allergy mouse model. For the immunotherapy evaluation, mice (n = 24) were intraperitoneally (i.p.) sensitized with 1 mg alum and 100 μg SAE in PBS on days 0, 7, and 14 and randomly divided into four groups of six: a negative control (NC) and high- to low-dose immunotherapy (HI, MI, and LI). The untreated group (n = 6) only received 1 mg alum in PBS (i.p.). All groups were challenged with 400 μg SAE (i.g.) on days 21, 22, 23, 53, and 58. Following the challenge, SAE-sensitized mice from the immunotherapy group were treated (i.p.) with 10 μg SAE for LI, 50 μg SAE for MI, and 100 μg SAE for HI on days 32, 39, and 46. The untreated and NC groups only received PBS (i.p.). All mice were euthanized on day 59. As the results, we found that SAE immunotherapy reduced systemic allergy symptom scores, serum IL-4 levels, IL-4 and FcεR1α mRNA relative expression, and mast cell degranulation in ileum tissue in allergic mice while increasing Foxp3 and IL-10 mRNA relative expression. Notably, we observed an increased ratio of IL-10 to IL-4 mRNA expression, demonstrating the efficacy of SAE immunotherapy in promoting desensitization. Thus, SAE can be developed as an immunotherapeutic agent for food allergies by inducing prolonged allergy tolerance with a wide range of allergen targets.

    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.

    G protein-coupled receptor 139 (GPR139), a highly conserved orphan receptor, is predominantly expressed in the habenula of vertebrate species. Habenula is an ancient epithalamic structure, which is critical to comprehending adaptive behaviors in vertebrates. We have previously demonstrated the role of GPR139 agonists in fear-associated decision-making processes in zebrafish. However, how GPR139 signaling in the habenula modulates such adaptive behavioral responses remains unsolved. Fish centrally administered with a synthetic antagonist for human GPR139 (NCRW0005-F05) exhibited significant suppression of odorant cue (alarm substance, AS)-induced fear learning in the conditioned place avoidance paradigm. On the other hand, co-treatment with a GPR139 antagonist and a synthetic agonist for human GPR139 (JNJ-63533054) interrupted the fear conditioning process by significantly reducing locomotion during post-conditioning. Calcium imaging of acute brain slices showed a significant increase in peak amplitude of calcium transients in the habenula upon bath application of either a GPR139 antagonist or agonist. Furthermore, KCl-evoked calcium transients were reduced by the GPR139 antagonist and co-treatment of the GPR139 antagonist-agonist. These results suggest that the GPR139 antagonist did not block the inhibitory action of the GPR139 agonist in the decision-making process during the fear-retrieval phase; however, solitarily, it functions in governing the fear consolidation process via activation of the ventral habenula neurons in zebrafish.

    Background and objectives A modified aligner appliance with nickel-titanium springs (MAA) is a relatively new appliance that has not received extensive attention in orthodontics. This study evaluated the patient-reported outcomes when orthodontic treatment was provided using a modified aligner appliance to treat mild lower incisor crowding. Materials and methods This prospective cohort study consisted of 42 patients (11 males and 31 females; mean age 21.69 ± 2.56 years) with mild crowding. Twenty-one patients were treated using a modified aligner with nickel-titanium springs, while the remaining patients were treated with a conventional fixed orthodontic appliance (FA). Patient responses regarding pain, discomfort, and difficulty in chewing, swallowing, and speaking were recorded using a visual analog scale (VAS) at six assessment times: 24 hours (T1), two days (T2), three days (T3), two weeks (T4), one month (T5), and two months (T6) after appliance application. Results The mean perceived pain and discomfort levels were generally lower in the traditional fixed appliance (FA) group than the modified aligner appliance with nickel-titanium springs group at most assessment times. However, no statistically significant differences were found between the two groups. Chewing difficulty levels were similar between the two groups with no substantial differences. Swallowing and speech difficulty were significantly higher in the MAA group compared to the FA group during the first two days of treatment (P < 0.008). Conclusions Patients using both types of orthodontic appliances experienced temporary discomfort, including pain and difficulty chewing. While the modified aligners appliance with nickel-titanium springs caused additional challenges with swallowing and speaking, these issues were resolved over time, allowing patients to adjust to the treatment.
