    The purpose of the study is to explore the shadow economy of violent extremism through charity lenses and factors associated with misuse of charitable giving in a global financial system. It reviews the emergency response situations like COVID-19 when financial needs are urgent with lacked monitoring and control over payment disbursement to vulnerable groups. It highlights several governments' significant steps to counter the illicit finance flow through 'public-face' charity organizations. Descriptive research was used to gather secondary data insights using published reports, articles, news portals, and policy briefs from renowned institutions. The findings depict four factors known as economic and capacity, socio-cultural, politico-legal, and global networks support in misuse of charitable giving to finance violent extremism. This study claims not all charitable giving misused for extremism and violence. However, there is a possibility that extremist groups could take advantage of using humanitarian organizations' face to finance violent extremism. Two possible recommendations have been made to overcome this issue by adopting digital payment mechanisms and community engagement to design and deliver the COVID-19 response recovery programs.

    With the rapid global spread of the COVID-19 pandemic, researchers from diverse fields of study have contributed markedly in different research aspects. Considering the substantial economic significance of the pandemic at the micro and macro level throughout the world, we review the scientific publications in the discipline of Economics. To draw a broad inference, we analyze a total of 1,636 scientific publications starting from 1974, which covers the period of earlier pandemics or epidemics that have a close association with COVID-19 using bibliometric analysis. Our analysis and mapping reveal key information related to the contributors at different levels, including author, institution, country, and publication sources. Besides, we identify the historical concentration of research using scientific clustering and illustrate transformations at different times. Moreover, recognizing the underlying inadequacy of economics research, we propose several areas of future research. Our findings and suggestions are expected to act as a roadmap to potential research opportunities and notable implications for business and policymakers.

    INTRODUCTION: Clinical audit is a quality improvement process that seeks to improve patient care and outcomes through the systematic review of care against explicit criteria and the implementation of change. The objective of this audit was to evaluate the quality of orthodontic chart documentation by dental undergraduates against established guidelines.

    MATERIALS AND METHODS: An audit checklist with 13 criteria for good documentation was adapted from guidelines proposed by the American Association of Orthodontists and British Orthodontic Society. Orthodontic chart documentation in 103 removable appliance therapy patients under 4th and 5th year dental undergraduates' care was retrieved from the electronic record of the University dental clinic and audited. The audit exercise explored in detail the thirteen criteria for good documentation and eight assessment attributes of the first criterion, namely, basic orthodontic examination. The level of compliance was measured as the percentage records meeting the criteria. The data were statistically analysed using SPSS 26.0 (SPSS, Inc., Chicago, IL, USA).

    RESULTS: There was no complete compliance for any of the criteria. Thirty-five (33.9%) patient charts reported basic orthodontic examination documentation adequately. Compliance was the highest for documentation of treatment modality (77.6%), appliance delivery encounters (77.6%), and appliance adjustment appointments (83.5%). About 51.4% of the 68 patient charts (treatment of 35 patients of the total 103 were in the progress stage) stated adequately the outcome of treatment. Only 22% of the 68 patient charts had the details for retention protocol. There was statistically significant difference in chart documentation between male and female students for basic orthodontic assessment and appliance delivery and patient instructions attributes.

    CONCLUSION: The clinical audit demonstrated poor compliance with the criteria for orthodontic chart documentation. The audit should be repeated after the provision of learning opportunities and self-critical analysis.

    INTRODUCTION: Dengue has become a more serious human health concern in China, with increased incidence and expanded outbreak regions. The knowledge of the cross-sectional and longitudinal epidemiological characteristics and the evolutionary dynamics of dengue in high-risk areas of China is limited.

    METHODS: Records of dengue cases from 2013 to 2016 were obtained from the China Notifiable Disease Surveillance System. Full envelope gene sequences of dengue viruses detected from the high-risk areas of China were collected. Maximum Likelihood tree and haplotype network analyses were conducted to explore the phylogenetic relationship of viruses from high-risk areas of China.

    RESULTS: A total of 56,520 cases was reported in China from 2013 to 2016. During this time, Yunnan, Guangdong and Fujian provinces were the high-risk areas. Imported cases occurred almost year-round, and were mainly introduced from Southeast Asia. The first indigenous case usually occurred in June to August, and the last one occurred before December in Yunnan and Fujian provinces but in December in Guangdong Province. Seven genotypes of DENV 1-3 were detected in the high-risk areas, with DENV 1-I the main genotype and DENV 2-Cosmopolitan the secondary one. The Maximum Likelihood trees show that almost all the indigenous viruses separated into different clusters. DENV 1-I viruses were found to be clustered in Guangdong Province, but not in Fujian and Yunnan, from 2013 to 2015. The ancestors of the Guangdong viruses in the cluster in 2013 and 2014 were most closely related to strains from Thailand or Singapore, and the Guangdong virus in 2015 was most closely related to the Guangdong virus of 2014. Based on closest phylogenetic relationships, viruses from Myanmar possibly initiated further indigenous cases in Yunnan, those from Indonesia in Fujian, while viruses from Thailand, Malaysia, Singapore and Indonesia were predominant in Guangdong Province.

    CONCLUSIONS: Dengue is still an imported disease in China, although some genotypes continued to circulate in successive years. Viral phylogenies based on the envelope gene suggested periodic introductions of dengue strains into China, primarily from Southeast Asia, with occasional sustained, multi-year transmission in some regions of China.

    BACKGROUND: Dengue is the most rapidly spreading mosquito-borne viral disease of humans worldwide, including southeast Asia region. This review provides a comprehensive overview of questionnaire-related dengue studies conducted in the Philippines and evaluates their reliability and validity in these surveys.

    METHODS: A review protocol constructed by a panel of experienced academic reviewers was used to formulate the methodology, research design, search strategy and selection criteria. An extensive literature search was conducted between March-June 2020 in various major electronic biomedical databases including PubMed, EMBASE, MEDLINE and ScienceDirect. A systematic review and meta-analysis (PRISMA) were selected as the preferred item reporting method.

    RESULTS: Out of a total of 34 peer-reviewed dengue-related KAP studies that were identified, 15 published from 2000 to April 2020 met the inclusion criteria. Based on the meta-analysis, a poor mean score was obtained for each of knowledge (68.89), attitude (49.86) and preventive practice (64.69). Most respondents were equipped with a good knowledge of the major clinical signs of dengue. Worryingly, 95% of respondents showed several negative attitudes towards dengue prevention, claiming that this was not possible and that enacting preventive practices was not their responsibility. Interestingly, television or radio was claimed as the main source of gaining dengue information (range 50-95%). Lastly, only five articles (33.3%) piloted or pretested their questionnaire before surveying, of which three reported Cronbach's alpha coefficient (range 0.70 to 0.90).

    CONCLUSION: This review indicates that to combat the growing public health threat of dengue to the Philippines, we need the active participation of resident communities, full engagement of healthcare personnel, promotion of awareness campaigns, and access to safe complementary and alternative medicines. Importantly, the psychometric properties of each questionnaire should be assessed rigorously.

    COVID-19 infection resulted in significant economic implications to patients as well as a considerable financial burden to the general population for preventive measures. A descriptive study was conducted among staff at one of the public universities in Malaysia to estimate the monthly out-of-pocket expenditures for preventive measures used for COVID-19 infection. The study tool includes questions on household out-of-pocket expenditure and the measurements of the impact of the expenditure on household income. It was found that the average cumulative monthly expenditures related to the preventive measures were US$ 45.90 (Ringgit Malaysia 187.77), which was 4.3% of the household income. The highest expenditures were for traditional and complementary medicine followed by nutraceutical/supplements and disposable facemask. 8% of the households in this study incurred more than ten per cents of their monthly household income for expenditures related to COVID-19 preventive measures. Several households are experiencing substantial financial implications for preventive measures related to COVID-19 infection. This study highlights the out-of-pocket expenditures incurred for preventive measures were substantial for certain households. Effective initiatives from the government on providing subsidized protective personal equipment and a cost-sharing approach could help to alleviate the household financial burden.

    The venoms of Asiatic kraits (Bungarus spp.) contain various neurotoxic phospholipases A2 (beta-bungarotoxins) which can irreversibly damage motor nerve terminals, resulting in rapidly fatal suffocation by respiratory muscle paralysis or oral airway obstruction. Hence, there is a need of adjunct therapy at the pre-hospital stage to prevent or delay the onset of neurotoxicity, so that antivenom can be given within golden hour before the envenoming becomes antivenom-resistant. This study investigated the efficacy of varespladib, a small molecule PLA2 (phospholipase A2) inhibitor, given as a bolus subcutaneously upon the onset of krait venom-induced paralysis in a mouse experimental envenoming and rescue model, where the severity of neurotoxicity was scored and the survival rate was monitored over 24 h. Varespladib at 10 mg/kg effectively alleviated the neurotoxicity of Bungarus sindanus, Bungarus multicinctus and Bungarus fasciatus venoms, and rescued all mice from venom-induced lethality (100% survival). Varespladib at this dose, however, only partially reduced the neurotoxicity of Bungarus caeruleus and Bungarus candidus venoms, while all challenged mice were dead by 23 h (B. caeruleus) and 12 h (B. candidus). An increased dose of varespladib at 20 mg/kg markedly abated the venom neurotoxicity past 8 h of envenoming, and protected the mice from venom lethality (B. caeruleus: 75% survival; B. candidus: 100% survival). The finding is consistent with previous studies which demonstrated varespladib's inhibitory effect against some snake venoms. The findings suggest varespladib could be repurposed as an emergency drug for prevention or rescue (if given early enough) from the acute, neurotoxic envenoming syndromes caused by various major krait species in Asia.

    Malaria control and elimination require prompt diagnosis and accurate treatment. Conventional methods such as rapid diagnostic tests (RDTs) and microscopy lack the characteristics to detect low parasitemias, commonly found in asymptomatic parasitemias and/or submicroscopic malaria carriers. On the contrary, molecular methods have higher sensitivity and specificity. This study evaluated the performance of two commercial real-time polymerase chain reaction (PCR) assays, RealStar® Malaria PCR (RealStar-genus) and RealStar Malaria Screen&Type PCR (RealStar-species), compared with the reference Nested Multiplex Malaria PCR, for the detection of the main five Plasmodium species affecting humans. A total of 121 samples were evaluated. Values of sensitivity (98.9% and 97.8%) and specificity (100% and 96.7%) of the RealStar-genus and the RealStar-species assays, respectively, were very good. The limit of detection (LoD) for the RealStar-genus assay showed a mean value of 0.28 parasites/µL with Plasmodium falciparum samples; while, the LoD of the RealStar-species assay ranged from 0.09 parasites/µL for P. vivax to two parasites/µL for P. ovale. The time to complete a diagnosis was established in 4 hours. Our findings showed a very good concordance of both assays compared with the reference method, with a very good analytical sensitivity. RealStar-species assay was able to correctly characterize double and triple infections. Therefore, these RealStar assays have shown to be useful tools in malaria diagnosis in non-endemic countries and even endemic countries, and for malaria control in general, detecting low parasitemias with sensitivity similar to the most sensitive methods as nested PCR, but with lower time to get the results.

    COVID-19 has become the focal point since 2019 after the outbreak of coronavirus disease. Many drugs are being tested and used to treat coronavirus infections; different kinds of vaccines are also introduced as preventive measure. Alternative therapeutics are as well incorporated into the health guidelines of some countries. This research aimed to look into the underlying mechanisms of functional foods and how they may improve the long-term post COVID-19 cardiovascular, diabetic, and respiratory complications through their bioactive compounds. The potentiality of nine functional foods for post COVID-19 complications was investigated through computational approaches. A total of 266 bioactive compounds of these foods were searched via extensive literature reviewing. Three highly associated targets namely troponin I interacting kinase (TNNI3K), dipeptidyl peptidase 4 (DPP-4), and transforming growth factor beta 1 (TGF-β1) were selected for cardiovascular, diabetes, and respiratory disorders, respectively, after COVID-19 infections. Best docked compounds were further analyzed by network pharmacological tools to explore their interactions with complication-related genes (MAPK1 and HSP90AA1 for cardiovascular, PPARG and TNF-alpha for diabetes, and AKT-1 for respiratory disorders). Seventy-one suggested compounds out of one-hundred and thirty-nine (139) docked compounds in network pharmacology recommended 169 Gene Ontology (GO) items and 99 Kyoto Encyclopedia of Genes and Genomes signaling pathways preferably AKT signaling pathway, MAPK signaling pathway, ACE2 receptor signaling pathway, insulin signaling pathway, and PPAR signaling pathway. Among the chosen functional foods, black cumin, fenugreek, garlic, ginger, turmeric, bitter melon, and Indian pennywort were found to modulate the actions. Results demonstrate that aforesaid functional foods have attenuating roles to manage post COVID-19 complications. PRACTICAL APPLICATIONS: Functional foods have been approaching a greater interest due to their medicinal uses other than gastronomic pleasure. Nine functional food resources have been used in this research for their traditional and ethnopharmacological uses, but their directive-role in modulating the genes involved in the management of post COVID-19 complications is inadequately studied and reported. Therefore, the foods types used in this research may be prioritized to be used as functional foods for ameliorating the major post COVID-19 complications through appropriate science.

    OBJECTIVES: To investigate pharmacy students' attitudes, subjective norms, perceived behavioural control, intentions and their behaviour towards patient safety using a theory of planned behaviour framework.

    DESIGN: Mixed-methods research.

    SETTING: Private university in Malaysia.

    PARTICIPANTS: Pharmacy undergraduate students participated in the study. There were 18 students participated in the qualitative study and 272 students responded to the survey questionnaire.

    METHODS: A convergent parallel-mixed method design, involving a quantitative survey and qualitative focus group discussions was used among pharmacy students in a private university in Malaysia. Qualitative data of transcribed verbatim texts were then subjected to a thematic content analysis framework. Multiple correlations were undertaken using the quantitative data to examine how the dependent variable (self-reported knowledge) related to the independent variables (attitudes, behavioural intentions, subjective norms, perceived behavioural control.

    PRIMARY OUTCOME: Pharmacy students' attitudes, subjective norms, perceived behavioural control, behavioural intentions constructs led to their behaviour towards patient safety.

    SECONDARY OUTCOME: The quantitative study revealed that there was a moderate positive correlation between students' self-reported knowledge and attitudes (r=0.48, p=0.03).

    RESULTS: Pharmacy students' attitudes and perceived behavioural control constructs had positive correlations with pharmacy students' self-reported knowledge on patient safety. There was no correlation between students' self-reported knowledge and subjective norms (r=0.27, p=0.23). There was a weak positive correlation between students' self-reported knowledge and perceived behavioural control (r=0.39, p=0.04). There was no correlation between students' self-reported knowledge and behavioural intention (r=0.20, p=0.56).

    CONCLUSIONS: Theory of planned behaviour constructs such as attitudes, subjective norms, perceived behavioural control and behavioural intentions of pharmacy students, defined their behaviour towards patient safety. Pharmacy students' attitudes and perceived behavioural control constructs were correlated with their self-reported knowledge on patient safety.

    BACKGROUND: COVID-19 pandemic has caused an extraordinary situation, especially for the healthcare workers (HCWs), leading to increased psychological stress. The aim of the study was to estimate the prevalence of different grades of anxiety and depression across different centers in the Philippines and identify demographic factors associated with them.

    DESIGN AND METHOD: A cross-sectional, web-based, multi-center study was conducted among HCWs of Philippines from April 20- May 20, 2020. The study instruments used were the Generalized Anxiety Disorder (GAD-7) scale and Patient Health Questionnaire (PHQ-9). Risk perception scores were analyzed using Mann-Whitney and Kruskal-Wallis test. Logistic regression was done to identify factors significantly associated with symptoms of anxiety and depression determined.

    RESULTS: A total of 516 HCWs were included in the study. Most of them have anxiety symptoms (70.74%), but only half of them have symptoms of depression (50.97%). In addition, gender, age, marital status, living status, occupation, work premises, and availability of mental health services were significantly associated with the participants' anxiety symptoms. In contrast, gender, marital status, occupation, and work premises were significantly associated with depression symptoms.

    CONCLUSION: This study reiterates the fact and demonstrates that COVID-19 has disrupted the mental well-being of HCWs in the Philippines. Majority of HCW was psychologically affected by COVID-19. Therefore, there is a dire need to address mental illness amongst HCWs and frame guidelines based on proven algorithms to overcome these mental illnesses.

    Malaysia was slow to begin its COVID-19 immunization program for various reasons. However, it is one of the fastest developing countries to vaccinate 80% of its adult population. Nontraditional health leadership played a large role in the implementation of the National COVID-19 Immunisation Programme (NCIP). Independent opinions from academia also helped the NCIP and may be useful as a way of pushing forward recommendations that may otherwise be difficult to make.

    BACKGROUND: The number of patients with Parkinson's disease among older adults is rapidly increasing. Such patients mostly take medication and require regular physician visits. However, the effect of physician visit frequency for the treatment for Parkinson's disease has not been evaluated. This study aimed to evaluate the impact of physician visit frequency for Parkinson's disease treatment on mortality, healthcare days, and healthcare and long-term care costs among older adults.

    METHODS: This study employed a retrospective cohort design utilizing claims data from the Fukuoka Prefecture Wide-Area Association of Latter-Stage Elderly Healthcare Insurance and Long-Term Care Insurance. Patients aged ≥75 years who were newly diagnosed with Parkinson's disease in 2014 were included in this study, following the onset of Parkinson's disease to March 31, 2019. We calculated the restricted mean survival time to evaluate mortality, focusing on the frequency of physician visits for Parkinson's disease treatment. Inpatient days, outpatient days, and healthcare and long-term care costs per month were calculated using a generalized linear model.

    RESULTS: There were 2224 participants, with 46.5% mortality among those with a higher frequency of physician visits and 56.4% among those with a lower frequency of physician visits. A higher frequency of physician visits was associated with a significant increase in survival time (1.57 months at 24 months and 5.00 months at 60 months) after the onset of Parkinson's disease and a decrease in inpatient days and healthcare costs compared to a lower frequency of physician visits.

    CONCLUSIONS: A higher frequency of physician visits was significantly associated with longer survival time, fewer inpatient days, and lower healthcare costs. Caregivers should support patients with Parkinson's disease to visit physicians regularly for their treatment.

    COVID-19 is a respiratory disease that causes infection in both lungs and the upper respiratory tract. The World Health Organization (WHO) has declared it a global pandemic because of its rapid spread across the globe. The most common way for COVID-19 diagnosis is real-time reverse transcription-polymerase chain reaction (RT-PCR) which takes a significant amount of time to get the result. Computer based medical image analysis is more beneficial for the diagnosis of such disease as it can give better results in less time. Computed Tomography (CT) scans are used to monitor lung diseases including COVID-19. In this work, a hybrid model for COVID-19 detection has developed which has two key stages. In the first stage, we have fine-tuned the parameters of the pre-trained convolutional neural networks (CNNs) to extract some features from the COVID-19 affected lungs. As pre-trained CNNs, we have used two standard CNNs namely, GoogleNet and ResNet18. Then, we have proposed a hybrid meta-heuristic feature selection (FS) algorithm, named as Manta Ray Foraging based Golden Ratio Optimizer (MRFGRO) to select the most significant feature subset. The proposed model is implemented over three publicly available datasets, namely, COVID-CT dataset, SARS-COV-2 dataset, and MOSMED dataset, and attains state-of-the-art classification accuracies of 99.15%, 99.42% and 95.57% respectively. Obtained results confirm that the proposed approach is quite efficient when compared to the local texture descriptors used for COVID-19 detection from chest CT-scan images.

    A novel hybrid nanofluid was explored in order to find an efficient heat-transmitting fluid to replace standard fluids and revolutionary nanofluids. By using tangent hyperbolic hybrid combination nanoliquid with non-Newtonian ethylene glycol (EG) as a basis fluid and a copper (Cu) and titanium dioxide (TiO2) mixture, this work aims to investigate the viscoelastic elements of the thermal transferring process. Flow and thermal facts, such as a slippery extended surface with magnetohydrodynamic (MHD), suction/injection, form factor, Joule heating, and thermal radiation effects, including changing thermal conductivity, were also integrated. The Keller-Box method was used to perform collective numerical computations of parametric analysis using governing equivalences. In the form of graphs and tables, the results of TiO2-Cu/EG hybrid nanofluid were compared to those of standard Cu/EG nanofluid in important critical physical circumstances. The entropy generation study was used to examine energy balance and usefulness for important physically impacting parameters. Detailed scrutiny on entropy development get assisted with Weissenberg number, magnetic parameter, fractional volumes, injection parameter, thermal radiation, variable thermal conductivity, Biot number, shape variation parameter, Reynolds and Brinkman number. Whereas the entropy gets resisted for slip and suction parameter. In this case, spotted entropy buildup with important parametric ranges could aid future optimization.

    Neuropsychiatric disorders (NPDs) are a huge burden to the patient, their family, and society. NPDs have been greatly associated with cardio-metabolic comorbidities such as obesity, type-2 diabetes mellitus, dysglycaemia, insulin resistance, dyslipidemia, atherosclerosis, and other cardiovascular disorders. Antipsychotics, which are frontline drugs in the treatment of schizophrenia and off-label use in other NPDs, also add to this burden by causing severe metabolic perturbations. Despite decades of research, the mechanism deciphering the link between neuropsychiatric and metabolic disorders is still unclear. In recent years, transient receptor potential Ankyrin 1 (TRPA1) channel has emerged as a potential therapeutic target for modulators. TRPA1 agonists/antagonists have shown efficacy in both neuropsychiatric disorders and appetite regulation and thus provide a crucial link between both. TRPA1 channels are activated by compounds such as cinnamaldehyde, allyl isothiocyanate, allicin and methyl syringate, which are present naturally in food items such as cinnamon, wasabi, mustard, garlic, etc. As these are present in many daily food items, it could also improve patient compliance and reduce the patients' monetary burden. In this review, we have tried to present evidence of the possible involvement of TRPA1 channels in neuropsychiatric and metabolic disorders and a possible hint towards using TRPA1 modulators to target appetite, lipid metabolism, glucose and insulin homeostasis and inflammation associated with NPDs.
