The pathogenicity and potential risk evaluation of Zika virus to cause mysterious "Disease X": A brief report.

Background and Aims: Disease X is included to represent an unknown pathogen that has the potential to spread globally and trigger significant epidemics. The World Health Organization (WHO) and the Global Alliance for Vaccine and Immunization (GAVI) recommend 10 potential disease organisms responsible for disease X. Among them, the Zika virus (ZIKV) is one of the potential organisms. The present work aimed to evaluate the current pathogenicity and potential risk of the ZIKV for public health emergencies. Methods: We performed a brief review of existing literature from available sources using Zika fever, Zika virus, and Flaviviridae as keywords and extracted relevant information for this review. Results: The primary way that the ZIKV transmits to humans is by mosquito bites (Aedes aegypti and Aedes albopictus). Typically, Aedes mosquitoes bite during the day. As an RNA virus, the ZIKV is well-known for its rapid mutation rate. ZIKV strains or variations can arise due to genomic mutations, and they occur through various processes, including replication errors, recombination, and selection pressure. Nowadays, the ZIKV has also evolved into a global pandemic because the four-amino acid sequence fits the envelope protein's 154 glycosylation motif, which may be involved in virulence. Conclusion: There is no specific medicine or vaccine available for the prevention or treatment of ZIKV infection. Therefore, personal protective measures should be the way to prevent ZIKV disease. Therefore, avoiding exposure is the best way to prevent problems from ZIKV to mosquitoes.

Green synthesis and characterization of zirconium nanoparticlefor dental implant applications.

Green synthesis is a promising and cost-effective technique to synthesize nanoparticles from plant extract. The present study shows the green synthesis of zirconium nanoparticles using the extract of ginger, garlic, and zirconium nitride. The obtained nanoparticles were studied for potential dental implant applications. The synthesized nanoparticles were characterized by Fourier Transform Infrared Spectroscopy (FTIR), Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive X-Ray Spectroscopy (EDX), X-Ray diffraction analysis (XRD), and antibacterial analysis. FTIR analysis confirmed the presence of various organic compounds in the synthesized nanoparticles. The synthesized nanoparticles were spherical, triangular, and irregular, with varying sizes confirmed by FESEM analysis. The nanoparticles synthesized from the combination of garlic and ginger, and zirconium exhibited potent antibacterial activity against S. aureus. Anti-biofilm, anti-microbial activity, biointegration formation, and cell mechanism survival are also mentioned. Thus, the synthesized nanoparticles can be a good candidate for a dental implant because of their excellent antimicrobial properties.

Problematic internet use and depressive symptoms among the school-going adolescents in Bangladesh during the COVID-19 pandemic: A cross-sectional study findings.

Background and Aims: Problematic internet use (PIU) by children and adolescents is a concern for many parents. Several factors, including students' education level, the method of instruction, the dependence on the internet, and their intended use of the internet, could all be contributing factors to PIU and depression. Disturbed mental health may be attributed to the cancellation of physical education classes because of the COVID-19 outbreak. This study aimed to assess the association of COVID-19 pandemic with PIU and depressive symptoms in adolescent students. Methods: We performed this cross-sectional study among 491 school-going adolescents of 10 to 16 years. Self-administered questionnaires were applied to collect sociodemographic information and the internet usage pattern of the participants. We measured the prevalence of PIU and depressive symptoms using the PIU questionnaire (PIUQ-SF-6) and patient health questionnaire-9 (PHQ-9). Results: The estimations of the risk group for PIU and depressive symptoms among school-going adolescents were 80.04% and 77.80%, respectively. The latent profiling of PIU scores for obsession, neglect, and control sub-groups were 5.82, 6.12, and 6.35, respectively. Moreover, we observed mild, moderate, and severe depressive symptoms in 48.68%, 27.70%, and 1.43% of cases. Age, education level, medium of education, financial impression, internet connection, the device used, the purpose for internet use, and the living status of respondents were significantly associated with the PIU. Reported mental health issues was associated with education level, medium of education, financial impression, and internet connection. Conclusion: The present study revealed an association of PIU and depressive symptoms with sociodemographic factors and internet usage patterns. Therefore, these results might have practical implications in clinical psychology, psychiatry, and psychotherapy. The healthcare professional can develop a context-specific comprehensive clinical intervention plan for children and adolescents.

Global landscape of COVID-19 vaccination progress: insight from an exploratory data analysis.

The next big step in combating the COVID-19 pandemic will be gaining widespread acceptance of a vaccination campaign for SARS-CoV-2. This study aims to report detailed Spatiotemporal analysis and result-oriented storytelling of the COVID-19 vaccination campaign across the globe. An exploratory data analysis (EDA) with interactive data visualization using various python libraries was conducted. The results show that, globally, with the rapid vaccine development and distribution, people from the different regions are also getting vaccinated and revealing their positive intent toward the COVID-19 vaccination. The outcomes of this exploration also established that mass vaccination campaigns in populated countries including Brazil, China, India, and the US reduced the number of daily COVID-19 deaths and confirmed cases. Overall, our findings contribute to current policy-relevant research by establishing a link between increasing immunization rates and lowering COVID-19's rising curve.

The COVID-19 vaccination experience in Bangladesh: Findings from a cross-sectional study.

OBJECTIVES: Vaccination rollout against COVID-19 has started in developed countries in early December 2020. Mass immunization for poor or low-income countries is quite challenging before 2023. Being a lower-middle-income country, Bangladesh has begun a nationwide COVID-19 vaccination drive in early February 2021. Here, we aimed to assess the opinions, experiences, and adverse events of the COVID-19 vaccination in Bangladesh. METHODS: We conducted this online cross-sectional study from 10 February 2021, to 10 March 2021, in Bangladesh. A self-reported semi-structured survey questionnaire was used using Google forms. We recorded demographics, disease history, medication records, opinions and experiences of vaccination, and associated adverse events symptoms. RESULTS: We observed leading comorbid diseases were hypertension (25.9%), diabetes (21.1%), heart diseases (9.3%), and asthma (8.7%). The most frequently reported adverse events were injection site pain (34.3%), fever (32.6%), headache (20.2%), fatigue (16.6%), and cold feeling (15.4%). The chances of having adverse events were significantly higher in males than females (p = 0.039). However, 36.4% of respondents reported no adverse events. Adverse events usually appeared after 12 h and went way within 48 h of vaccination. Besides, 85.5% were happy with the overall vaccination management, while 88.0% of the respondents recommended the COVID-19 vaccine for others for early immunization. CONCLUSION: According to the present findings, reported adverse events after the doses of Covishield in Bangladesh were non-serious and temporary. In Bangladesh, the early vaccination against COVID-19 was possible due to its prudent vaccine deal, previous mass vaccination experience, and vaccine diplomacy.

Data set concerning the use of social networking sites and mental health problems among the young generation in Bangladesh.

The article depicts a unique dataset of responses from 791 adults to a self-made questionnaire of five sections sent via Google survey tool (Google form) from February 4, 2021, to March 18, 2021 [1]. We collected responses for establishing a paradigm of the relationship between the social networking sites (SNS) use and four dimensions of psychological distress including depression, anxiety, loneliness, and sleep disturbances. Facebook is the most popular social media in Bangladesh, we observed 669 Facebook users and 122 non-Facebook-users aged between 15 to 40 years in this data set. We analyzed the collected data using the Microsoft Excel (version 2016) and presented as frequencies and percentages based on responses to the whole survey. The survey contained items focusing on (i) sociodemographic information, (ii) usage patterns of SNS, (iii) assessment of mental health problems. We collected responses from all across the country regardless of sociodemographic background. Therefore, government authorities and healthcare providers can use this data for dealing with the mental health issues concerning the use of SNS.

Hematological abnormalities and comorbidities are associated with COVID-19 severity among hospitalized patients: Experience from Bangladesh.

BACKGROUND: The hematological abnormalities are assumed to be involved in the disease progression of COVID-19. However, the actual associations between specific blood parameters and COVID-19 are not well understood. Here we aimed to assess the correlations between hematological parameters and the severity of COVID-19. METHODS: We included COVID-19 patients who were admitted to Evercare Hospital Ltd, Dhaka, Bangladesh, between November 10, 2020, to April 12, 2021, with a confirmed case of RT-PCR test. We recorded demographic information, clinical data, and routine hematological examination results of all COVID-19 patients. We performed statistical analyses and interpretation of data to compare severe COVID-19 patients (SCP) and non-severe COVID-19 patients (NSCP). RESULTS: The age and BMI of the admitted COVID-19 patients were 48.79±8.53 years and 25.82±3.75 kg/m2. This study included a total of 306 hospitalized COVID-19 patients. Among them, NSCP and SCP were 198 and 108, respectively. And we recorded 12 deaths from SCP. We observed the alterations of several hematological parameters between SCP and NSCP. Among them, we noticed the increased levels of C-reactive protein (CRP), d-dimer, and ferritin showed good indicative value to evaluate the severity of COVID-19. Also, there were positive correlations among these parameters. Moreover, we found correlations between the outcomes of COVID-19 patients with patient's demographics and comorbid diseases. CONCLUSION: Based on our results, CRP, d-dimer, and ferritin levels at admission to hospitals represent simple assessment factors for COVID-19 severity and the treatment decisions at the hospital setup. These blood parameters could serve as indicators for the prognosis and severity of COVID-19. Therefore, our study findings might help to develop a treatment protocol for COVID-19 patients at the hospital setup.
