Authors: Sansone Vincenza , Miraglia del Giudice Grazia , Della Polla Giorgia , Angelillo Italo Francesco
Published: March 2024

Background: This cross-sectional survey investigated the knowledge, attitudes, and coverage of recommended vaccinations among a random sample of patients with chronic medical conditions, at higher risk of vaccine-preventable diseases (VPDs), in Italy. Methods: The survey was conducted via telephone-based interviews. Results: Multinomial regression analysis showed that the patients who believed that VPDs were severe were more likely to know one recommended vaccination; those who believed that VPDs were severe and those who were advised from a general practitioner (GP) were more likely to know two vaccinations; those who were older, graduated, with more time from diagnosis, who believed that VPDs were severe, who did not need additional information, and who were advised from a GP were more likely to know three or four vaccinations. Patients who knew at least one vaccination, who perceived themselves at risk, and who were advised from a GP were more likely to have received one vaccination; those who knew more than one vaccination and who were advised from a GP were more likely to receive two or three vaccinations. Among the unvaccinated, patients who were unmarried/not cohabiting, those who needed information, and who believed that vaccinations were useful and safe were more willing to receive the recommended vaccinations. Conclusions: Educational interventions are needed to improve the adherence of individuals with chronic medical conditions.

Published: March 2024

To ensure that limited domestic resources are invested in the most effective interventions, immunization programs in low- and middle-income countries (LMICs) must prioritize a growing number of new vaccines while considering opportunities to optimize the vaccine portfolio, as well as other components of the health system. There is a strong impetus for immunization decision-making to engage and coordinate various stakeholders across the health system in prioritization. To address this, national immunization program decision-makers in LMICs collaborated with WHO to structure deliberation among stakeholders and document an evidence-based, context-specific, and transparent process for prioritization or selection among multiple vaccination products, services, or strategies. The output of this effort is the Country-led Assessment for Prioritization on Immunization (CAPACITI) decision-support tool, which supports using multiple criteria and stakeholder perspectives to evaluate trade-offs affecting health interventions, taking into account variable data quality. Here, we describe the user feedback from Indonesia and Ethiopia, two initial countries that piloted the CAPACITI decision-support tool, highlighting enabling and constraining factors. Potential immunization program benefits and lessons learned are also summarized for consideration in other settings.

Published: March 2024

Porcine circovirus type 2 (PCV2) is the main pathogen causing post-weaning multisystemic wasting syndrome (PMWS), which mainly targets the body’s immune system and poses a serious threat to the global pig industry. 5-Azacytidine is a potent inhibitor of DNA methylation, which can participate in many important physiological and pathological processes, including virus-related processes, by inhibiting gene expression. However, the impact of 5-Aza on PCV2 replication in cells is not yet clear. We explored the impact of 5-Aza on PCV2 infection utilizing PK15 cells as a cellular model. Our objective was to gain insights that could potentially offer novel therapeutic strategies for PCV2. Our results showed that 5-Aza significantly enhanced the infectivity of PCV2 in PK15 cells. Transcriptome analysis revealed that PCV2 infection activated various immune-related signaling pathways. 5-Aza may activate the MAPK signaling pathway to exacerbate PCV2 infection and upregulate the expression of inflammatory and apoptotic factors.

Published: March 2024

The higher-order nonlinear Schrödinger equation with combined nonlinearities is derived by an asymptotic reduction from the (2+4) Korteweg–de Vries model for weakly nonlinear wave packets for the context of interfacial waves in a three-layer symmetric media. Focusing properties and modulation instability effects are discussed for the considered physical context. Instability growth rate, maximum of the increment and the boundaries of the instability interval are derived in terms of three-layer density stratification, their structure on the parameter planes of relative layer depth, carrier wavenumber and envelope amplitude, are considered in detail.

Published: March 2024

The parameters of the GR4J-CemaNeige coupling model (GR4neige) are typically treated as constants. However, the maximum capacity of the production store (parX1) exhibits time-varying characteristics due to climate variability and vegetation coverage change. This study employed differentiable parameter learning (dPL) to identify the time-varying parX1 in the GR4neige across 671 catchments within the United States. We built two types of dPL, including static and dynamic parameter networks, to assess the advantages of the time-varying parameter. In the dynamic parameter network, we evaluated the impact of potential evapotranspiration (PET), precipitation (P), temperature (T), soil moisture (SM), and normalized difference vegetation index (NDVI) datasets on the performance of dPL. We then compared dPL with the empirical functional method (fm). The results demonstrated that the dynamic parameter network outperformed the static parameter network in streamflow estimation. There were differences in streamflow estimation among the dynamic parameter network driven by various input features. In humid catchments, simultaneously incorporating all five factors, including PET, P, T, SM, and the NDVI, achieved optimal streamflow simulation accuracy. In arid catchments, it was preferable to introduce PET, T, and the NDVI separately for improved performance. dPL significantly outperformed the empirical fm in estimating streamflow and uncalibrated intermediate variables, like evapotranspiration (ET). Both the derived parX1 from dPL and the empirical fm exhibited significant spatiotemporal variation across 671 catchments. Notably, compared to parX1 obtained through the empirical fm, parX1 derived from dPL exhibited a distinct spatial clustering pattern. This study highlights the potential of dPL in enhancing model accuracy and contributes to understanding the spatiotemporal variation characteristics of parX1 under the influence of climate factors, soil conditions, and vegetation change.
Biological Treatment of Nitroaromatics in Wastewater
Authors: Gupta Swati , Ronen Zeev
Published: March 2024

Nitroaromatic compounds (NACs), which are widely used in pesticides, explosives, dyes, and pharmaceuticals, include nitrobenzene, nitrotoluenes, nitrophenols, and nitrobenzoates. They are also significant industrial pollutants in the environment. These substances, as well as their derivatives, frequently have toxic or mutagenic properties. Wastewater containing nitroaromatic compounds can be effectively managed by using biological treatment methods that are accessible, cost-effective, and environmentally friendly. This review highlights the latest developments in biological treatment systems for removing NACs from wastewater. The large-scale implementation of biological treatment systems will be facilitated by future studies that focus on identifying the best operational methods and that determine how co-pollutants impact the removal of NACs from wastewater.

Published: March 2024

Background: The underrepresentation of BIPOC youth in the fields of public health, medicine, and research may be a factor contributing to the disproportionate rates of health disparities in BIPOC communities. In 2004, the Sullivan Commission on Diversity in the Healthcare Workforce, commissioned by the White House and led by the United States Health and Human Services, recommended efforts to increase the number of minority professionals in the aforementioned fields as necessary for addressing racial and ethnic health disparities. More recently, over 240 municipalities in the United States have declared “racism a public health crisis”. This national declaration links racism directly to public health disparities, thus calling for a public health response. The Flint Public Health Youth Academy (FPHYA) provides an effective model of youth engagement steeped in Equity, Diversity, and Inclusion (EDI). FPHYA was created based on a dissertation study designed to explore the motivators for engagement of African American and other minority students into careers in public health and its six recommendations. Methods: The FPHYA Model described in this article uses a case study of the Flint Water Crisis to assess and explore effective youth engagement models for public health. This model is rooted in the Continuum of Community Engagement and Youth Empowerment Theory and explores FPHYA’s contribution of youth voice in operationalizing racism as a public health crisis.

The aim of this study is to construct a curated bibliographic dataset for a landscape analysis on Health Artificial Intelligence (HAI) research.

Data Source:
We integrated HAI-related bibliographic records, including publications, open research datasets, patents, research grants, and clinical trials from Medline and Dimensions.

Methods:
Searching: Relevant documents were identified using Medical Subject Headings (MeSH) and Field of Research (FoR) indexed by 2 bibliographic databases, Medline and Dimensions. Extracting: MeSH terms annotated from the aforementioned bibliographic databases served as the primary information for our processing. For document records lacking MeSH terms, we re-extracted them using the Medical Text Indexer (MTI). Mapping: In order to enhance interoperability, HAI multi-documents were organized using a mapping system incorporating MeSH, FoR, The International Classification of Diseases (ICD-10), and Systematized Nomenclature of Medicine Clinical Terms (SNOMED CT). Integrating: All documents were curated based on a pre-defined ontology of health problems and AI technologies from the MeSH hierarchy.

Results:
We collected 96,332 HAI documents (publications: 75,820, open research datasets: 638, patents: 11,226, grants: 6,113, and clinical trials: 2,535) during 2009 to 2021. On average, 75.12% of the documents were tagged with at least one label related to either health problems or AI technologies (with 92.9% of publications tagged).

Summary:
This study presents a comprehensive pipeline for processing and curating HAI bibliographic documents following the FAIR (Findable, Accessible, Interoperable, Reusable) standard, offering a valuable multidimensional collection for the community. This dataset serves as a crucial resource for horizontally scanning the funding, research, clinical assessments, and innovations within the HAI field.
Metric-Independent Mitigation of Unpredefined Bias in Machine Classification
Authors: Tang Zhoufei , Lu Tao , Li Tianyi
Published: March 2024

In this study, we evaluate the “propose-review” framework for the mitigation of bias in machine classification. The framework considers Bob, who aims to protect sensitive dimensions from discrimination, and Alice, who sends proposals to Bob for using his data to construct a target classifier. The goal is to minimize discrimination in Bob’s protected dimension while preserving the desired separating capability of Alice’s classifier. The method does not assume predefined bias terms, does not anchor on specific fairness metrics, and is independent of Alice’s classifier choice. We consider that data attributes have different concentrations of the latent bias axes; assessing attributes’ concentrations in the ruled bias hyperspace helps identify bias-prone attributes and inform bias-mitigating data transforms. To this end, we assess attributes’ contribution to the separating capability of Bob’s conceptual classifier. We then compute the pairwise distances between attributes, and by applying multidimensional scaling to the distance matrix, we infer the axes of bias and establish a bias-attribute mapping. Bias mitigation is achieved by greedily applying appropriate data transforms to bias-prone attributes. The method works desirably across 21 classifiers and 7 datasets, bringing about substantial bias reduction under different choices of the protected dimension and the fairness metric. Compared to adversarial debiasing, the method better exploits the fairness-utility trade-off in machine classification.

Published: March 2024

The accuracy of the model can be one of the main indicators, on a basis of which it is possible to conclude about the suitability of the model for its practical operation. However, taking into account the specifics of the identified task, it is also worth paying attention to the speed of the model, since there is a need to process data in streaming mode. To investigate the possibilities of using machine learning in an applied problem, two groups of object recognition models considered: YOLOv5 and Faster R-CNN. The purpose of the study is to analyze the architectural solutions of the most common object detection models YOLOv5 and Faster R-CNN to build a model to improve the speed and accuracy of object detection in an applied task or further combine them. A total of 550 training images and 105 validation images collected. A dataset of 573 images from the new location also collected for final validation of the models. The use of Roboflow provided for image annotation, which allows not only to mark images, but also to export annotated data sets in various formats. Training and validation of the models carried out on the Google Colab platform. The platform uses the Python programming language and the PyTorch framework. The yolov5 and detecron2 libraries for YOLOv5 and Faster R-CNN, respectively, used for model training and validation. To determine whether the result belongs to one of the four groups, the IOU metric is used, which is the ratio of the intersection area to the area of the union of the correct and predicted bounding frames. The size of the trained YOLOv5 and Faster R-CNN models was 40.2 MB and 230.8 MB, respectively. The models tested on the second validation set. As result of the study, a set of data from video surveillance cameras collected and anno-tated using RoboFlow. The main representatives of two groups of object detection algorithms YOLOv5 and Faster R-CNN trained using the prepared data set. The results showed that both models have their advantages and disadvantages, both models are applicable for different tasks.

Using the method of nonlinear recursive analysis for detecting DDOS anoma-lies in time series data
Authors: Taras Hulyi , Vasily Belozyorov
Published: March 2024

This research endeavors to address this gap by determining a qualitative char-acteristic for server network traffic and use it to construct the corresponding recur-rence plot (RP). The goal of this study is to develop and assess a novel technique based on nonlinear recursive analysis to detect Distributed Denial of Service (DDoS) anomalies in network traffic time series data. With the increasing frequency of DDoS attacks on modern digital infrastructures, there is a pressing need for more efficient and accurate detection methods. There has been some attempts to apply nonlinear analysis to network traffic [2-4], but those studies lack critical steps in determining parameters for embedding space dimension and delay time . More recent studies have explored machine learning and deep learning approaches [7], which offer improved accuracy but can be computationally intensive and require extensive training data. Despite the advance-ments, there remains a need for a method that is both accurate and efficient, espe-cially in real-time detection scenarios. The researchers employed nonlinear recursive analysis by estimating RQA pa-rameters and determining a qualitative characteristic of data points of DDoS attack contained in CIC-IDS2017 dataset. A technique for determining hidden information for this series and its use for constructing the corresponding recurrence diagram (RP) at the points of information retrieval are described. It is shown that the use of RP has significant drawbacks associated with the visualization of information on a computer monitor screen, so another way of research is proposed - the calculation of numerical indicators of RP The given calculated RP indicators made it possible to typify the received data and determine the type, which was named "DDOS-RP", which makes it possible to distinguish some types of DoS/DDoS type attacks. The study concludes by recom-mending further exploration of this method in diverse network environments and against more complex DDoS attack patterns.

Testudo hermanni is considered near threatened globally in the wild. In this study differential leukocyte percentages, nuclear abnormalities, and erythrocyte morphology abnormalities of Testudo hermanni populations from two different habitat types in the Thrace Region were determined to whether habitats have a potential effect on blood cells. A total of 37 tortoises, 18 from an open habitat in Kırklareli/Karakoç, and 19 from an isolated habitat in Edirne/Keşan were studied. According to the results obtained from the Micronucleus Test, which detects genotoxic damage, there was no statistically significant difference between the two habitats. There were statistically significant differences in erythrocyte morphology abnormalities and differential leukocyte count between two populations, such as frequencies of anucleated erythrocyte, nuclear shift, elliptical shape distortion, monocyte and eosinophile percentages. This is the first study examined nuclear abnormalities of Testudo hermanni in Türkiye.

The existence of this interest can indirectly affect the existence of fast-food retail because of negative consumer perceptions related to fast-food retail. Therefore, several fast-food retailers have offered eco-friendly products, in great demand by Millennials. However, it is still rare for fast-food retailers to launch new outlets with green themes due to the adverse insight of fast food itself. It is also caused by data deficiency on consumer behavior intention towards green fast-food retail, even though the existence of this restaurant itself continues to increase, especially in West Java. Therefore, this study aims to examine the intention of millennial consumers in West Java’s green fast-food retail by applying the Theory-of-Planned-Behavior approach with the role of green knowledge, perceived green practices, perceived physical servicescape, and perceived price fairness. 402 respondents were gathered in this study by implementing TPB theory as the variable under study, supported by Green Knowledge, Perceived Green Practices, Perceived Physical Servicescape, and Perceived Price Fairness. A quantitative approach is employed and processed using SPSS and Smart-PLS. Based on the results, the company's green practices, physical service scape, and price fairness affect consumer behavior control which leads to a positive influence on consumer behavior intention in green fast-food retail. Another result proved that green knowledge has a positive and significant impact on consumer attitude
