Scalable Facial Authentication System for a Distributed Environment Using Feature Dimensionality Reduction
Authors: MFITUMUKIZA Joseph , KIM Tae Yong
Published: January 2023

The user authentication of personal identification using a face image relies on biometric features known as facial features. A facial authentication system is critical for access control and intelligent human computer interaction. However, the challenges include numerous training data requirement and high processing power due to computational complexity. Therefore, this paper proposes a scalable face authentication system for a distributed environment using feature dimensionality reduction (FDR). This study contributes to a constructive comparison of classical and state-of-the-art feature extraction techniques to develop of distributed environment-based scalability using FDR. The scalability for the distributed environment, is proven to extend the user access capacity by overcoming the multiple training data requirements while the new end-user access is authenticated in system. The accuracy and processing time were chosen as the performance metrics evaluating the proposed method. The features extracted using deep convolutional neural network (DCNN) as the state-of-the-art algorithm reveal remarkable performance using FDR with the principal component analysis algorithm and support vector machine for classification, compared to classical feature vector extractor algorithms such as the Gabor filter, histogram of oriented gradient and local binary pattern. The experimental results on the FERET dataset, demonstrate that the feature extracted by the DCNN is a more robust representation of scalability with up to 50% for FDR using half the processing time compared to the facial feature extracted using classical methods.

Published: January 2023

Purpose Exercise training may influence on appetite hormones and energy homeostasis.
Aims The purpose of the current study was to investigate the effect of resistance training with elastic band (ERT) on ghrelin (GHRL) and Obestatin (OBST) hormone concentration changes in overweight men.
Methods 20 male overweight (25<BMI≤29.5 kg/m2) voluntary participated in the current study and randomly assigned in the resistance training with elastic bands (ERT; n=10), and control (Con; n=10). Elastic resistance training was done three sessions in week in nonconsecutive for eight weeks. Blood sample was gathered before ERT and was repeated 48 hour interval with the last session of exercise training. GHRL and OBST were assessed in the plasma. Also, functional capacity (Push UP: PU; Squat: SQ) was assessed, and body fat percentage (BF %) were estimated.
Results We found that there was a significant difference in GHRL in the ERT than control [time× group (p=0.045; F=4.38)], however, there was no significant difference in OBST (p˃0.05). It was also seen that the interactive effect of time in the ERT (time× group) was significant for PU and SQ [(p=0.004; F=8.02), and SQ (p=0.011; F=8.1], respectively. Also, a decrease was seen in BF% in the ERT than control (p≤0.001).
Conclusion Finally, it can be concluded elastic resistance training with elastic bands have an positive impact on the functional capacity and appetite hormones and should be taken into consideration in the design of weight control protocols.

T-cells, being the major player in adaptive immune system mediating cellular immunity, have become a central focus for engaging the immune system in fighting against cancer. Their activation is initiated by recognition of antigen/major histocompatibility complexes by the T-cell receptor (TCR) and enhanced by engagement of co-stimulatory receptor. In recent years, various immunotherapies deploying T-cell immunity have made immense progress, including chimeric antigen receptor (CAR)-T therapy, checkpoint blockage, and CD3-based bispecific antibodies. Here we report the development of a novel trispecific antibody to CD19, CD3, and CD28, with an emphasis on the co-engagement of both CD3/TCR complex and CD28 co-stimulatory receptor for sustained T cell activation. Compared with the BiTE-CD19xCD3 lacking the co-stimulatory domain, the trispecific antibody augmented T cell proliferation and differentiation into memory T cells. It induced faster tumor cell lysis than the bispecific antibody, preferably through direct tumor lysis by CD8 T cells. RNAseq analysis revealed that the trispecific antibody modulates TCR complex-derived signal at multiple aspects, including amplification of transcriptional factors, promoting production of cytokines, positive regulation of cell cycle, and upregulation of anti-apoptotic factors to influence survival of T-cells. Markedly increased tumor inhibition effects and prolonged survival were observed in vivo in humanized mouse model. By extra engagement of a co-stimulatory receptor to prolong the survival of activated T cells, our study has proposed another possibility to extend the pharmacology effect of tandem single-chain variable fragments (scFv)-based antibody, which is worthy of further exploration in clinical trial settings.

Authors: ElOuazzani Hafsa , Oudghiri Mohammed Yassaad , Abbas Salma , Regragui Asmaa , Elouahabi Abdessamad , Cherradi Nadia
Published: January 2023

Background: Primary leptomeningeal melanoma is an extremely rare type of intracranial melanoma. It cannot be reliably distinguished from metastatic melanoma on neuroimaging and histopathological characteristics alone; its diagnosis is established only after exclusion of secondary metastatic disease from a cutaneous, mucosal or retinal primary [1, 2]. Prognosis is poor, partly due to its high rate of misdiagnosis.
Case presentation: We report a case of a Primary Meningeal Melanoma of the skull base with Melanomatosis, in 31 years old man, mimicking clinical and radiological features of meningioma and whose delayed treatment has worsened the prognosis.
Conclusion: Through this case, we highlight the diagnostic difficulties and we discuss the histopathological differential diagnoses especially with other pigmented lesions of Central nervous system (CNS).
Phase Transition in a Phonon Gas With Pair Correlations
Authors: Poluektov Yuri
Published: January 2023

The phase transition to the state of a phonon gas with pairwise correlations of interacting phonons with opposite momenta is studied. A method for describing such phonon systems within the framework of the self-consistent field model is developed and their thermodynamic characteristics are calculated. It is shown that a phonon gas with pair correlations can exist in a state of unstable thermodynamic equilibrium. The possibility of experimental observation of a solid in such a phase is discussed.

A metagenomic survey on Solanum tuberosum virome revealed environmental contamination of a laboratory-developed strain of SARS-CoV-2
Authors: Hassanpour Mina , Mohebbi Alireza
Published: January 2023

Metagenomics is a promising approach to discovering viral sequences in environmental samples. We used recently published RNA-Seq data ofSolanum tuberosum(S. tuberosum) from China for a metavirome study. Several environmentally related non-intact viruses read from forest animals, moths, bacteria, and amoeba were detected. Further investigation resulted in non-indigenous sequences of SARS-CoV-2 genomes of lineage B with novel substitutions. Three substitutions, including A22D and A36V in the envelope protein and Q498H in the spike glycoprotein that were recently reported from a laboratory strain virus with enhanced virulence, were detected in all samples. Further substitutions at ORF1ab were also uncovered. These were L1457V, D4553N, W6538S, I1525T, D1585Y, D6928G, N3414K, T3432S. Two unexpected frameshifts, ORF1a:2338–4401 and ORF1a:3681–4401, were noticed within the ORF1ab. The genomic evidence and geographical evidence of lab leaks are also provided. The findings of the presented study highlight the threats of the emerged potentially severe genotypes bearing substitutions that are not yet clinically reported. More studies are warranted to uncover the role of the novel substitutions in the severity of SARS-coV-2
A Case of Pulmonary Tuberculosis Followed by Penicilliosis Marneffei without HIV Infection
Authors: Yang Wei , Xu Xiaofeng
Published: January 2023

Background: Penicilliosis marneffei（P. Marneffei） is an important opportunistic pathogen found in in human immunodeficiency virus（HIV）-positive individuals. But there are few reports that tuberculosis （TB） patients are followed by P. Marneffeiwithout HIV Infection.
Case presentation:A female patient, aged 45, admitted to a local hospital in 2008 due to fever and cough. The patient received transbronchial needle aspiration under bronchoscopy, and the smear indicated positive for acid-fast bacilli. Therefore, the patient began to receive 2HRZE/7HR regimen on May 23, 2009 untill to February 2010. The patient returned to normal.On April 25,2014, the patient had fever again and received HRZEMfx regimen. Two weeks late, the patient still had fever. He received lymph node biopsy and was confirmed as P. Marneffeiby pathological examination, tissue culture and transmission electron microscopy analysis. Multiple HIV tests were all negative.Patient’s fever subsided after intravenous infusion of voriconazole for 2 weeks, and the patient recovered after oral administration of the same dose of voriconazole tablets for 6 months.
Conclusions: After the regular anti-TB treatment and stability, TB patients again have the clinical manifestations such as fever, swollen lymph nodes, etc. We cannot simply consider TB recurrence or resistance. Clinicians need to consider the possibility of infection with other pathogens.

Published: January 2023

Background:Controversies concerning the safety of sodium benzoate/ascorbic acid combination have remained grounds for continued scientific investigations. However, there is a dearth of scientific literature on its effect on the brain. This study investigated the effects dry-food added sodium benzoate/ascorbic acid combination on neurobehaviour, brain oxidative stress and inflammatory cytokines in mice.
Methods: Adult male mice were assigned into ten groups of 10 mice each. The groups are: one group fed standard diet, three groups fed diet containing sodium benzoate (NaB) at 125 mg/kg with ascorbic acid (AA) at 100, 200 or 300 mg/kg of feed, another three groups fed NaB at 250 mg/kg with AA at 100, 200 or 300 mg/kg of feed respectively, and the last three groups fed NaB at 500 mg/kg with AA at 100, 200 or 300 mg/kg respectively. Behavioural tests were assessed following which animals were sacrificed and their brains homogenised for the assessment of biochemical parameters. Results: The result showed a decrease in body weight, self grooming, total antioxidant capacity and inflammatory cytokines, mixed response with food intake, locomotor activity, Y maze spatial working memory and anxiety related behaviours and an increase in rearing and radial arm maze spatial working memory.
Conclusion: Dry food added NaB/AA altered behavioural, oxidative and inflammatory markers in mice. While not indicating outright deleterious effects at the concentrations used, the results suggest the need for further investigations into the effects of their combination, especially, when we consider their wide range of applications in the food industry.
Proposing magnetoimpedance effect for neuromorphic computing

Published: January 2023

Oscillation of physical parameters in materials can result in a peak signal in the frequency spectrum of the voltage measured from the materials. This spectrum and its amplitude/frequency tenability, through the application of bias voltage or current,can be used to perform neuron-like cognitive tasks. Magnetic materials, after achieving broad distribution for data storage applications in classical Von Neumann computer architectures, are under intense investigation for their neuron-like computing capabilities. A recent successful demonstration regards magnetisation oscillation in magnetic thin films by spin transfer or spin orbit torques accompanied by magnetoresistance (MR) effect that can give a voltage peak in the frequency spectrum of voltagewith bias current dependence of both peak frequency and amplitude. Here we use classical magnetoimpedance (MI) effect in amagnetic wire to produce such a peak and manipulate its frequency and amplitude by means of the bias voltage. We applied a noise signal to a magnetic wire with high magnetic permeability and owing to the frequency dependence of the magnetic permeability we got frequency dependent impedance with a peak at the maximum permeability. Frequency dependence of the MI effect results in different changes in the voltage amplitude at each frequency when a bias voltage is applied and therefore a shift in the peak position and amplitude can be obtained. The presented method and material provide optimal features instructural simplicity, low-frequency operation (tens of MHz-order) and high robustness at different environmental conditions.Our universal approach can be applied to any system with frequency dependent bias responses.

Published: January 2023

Background
We sought to decipher transmission pathways in healthcare-associated infections with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) within our hospital by epidemiological work-up and complementary whole genome sequencing (WGS). We report the findings of the four largest epidemiologic clusters of SARS-CoV-2 transmission occurring during the second wave of the pandemic from 11/2020-12/2020.
Methods
At the University Hospital Basel, Switzerland, systematic outbreak investigation is initiated at detection of any nosocomial case of Coronavirus disease of 2019 (COVID-19), defined as polymerase chain reaction (PCR)-confirmed SARS-CoV-2 infection occurring more than five days after admission. Clusters of nosocomial infections, defined as the detection of at least two positive patients and/or healthcare workers (HCWs) within one week with an epidemiological link, were further investigated by WGS on respective strains.
Results
The four epidemiologic clusters included 40 patients and 60 HCWs. Sequencing data was available for 70% of all involved cases (28 patients and 42 HCWs), confirmed epidemiologically suspected in house transmission in 33 cases (47.1% of sequenced cases) and excluded transmission in the remaining 37 cases (52.9%). Among cases with identical strains, epidemiologic work-up suggested transmission mainly through a ward-based exposure (24/33, 72.7%), more commonly affecting HCWs (16/24, 66.7%) than patients (8/24, 33.3%), followed by transmission between patients (6/33, 18.2%), and among HCWs and patients (3/33, 9.1%, respectively two HCWs and one patient).
Conclusions
Phylogenetic analyses revealed important insights into transmission pathways supporting less than 50% of epidemiologically suspected SARS-CoV-2 transmissions. The remainder of cases most likely reflect community-acquired infection randomly detected by outbreak investigation. Notably, most transmissions occurred between HCWs, possibly indicating lower perception of the risk of infection during contacts among HCWs.

Authors: Laureti Lucio , Costantiello Alberto , Leogrande Angelo
Published: January 2023

In this article we estimate the level of Government Effectiveness-GE in 193 countries in the period 2011-2020 using data of the ESG World Bank Database. Different econometric techniques are used i.e. Panel Data with Random Effects, Panel Data with Fixed Effects, and Pooled OLS. Results show that GE is positively related among others to “Control of Corruption”, “Political Stability and Absence of Violence/Terrorism”, and negatively associated with “Percentage Annual GDP Growth”. We perform a cluster analysis with the k-Means algorithm optimized with the Elbow Method and we find the presence of four clusters. Finally, we confront eight machine learning algorithms for the prediction of GE. Results show that the Polynomial Regression is the best predictive algorithm. The value of GE is expected to growth on average by 15.97%.

The rapid emergence of SARS-CoV-2 variants with high severity and transmutability adds further urgency for rapid and multiplex molecular testing to identify the variants. A nucleotide matrix-assisted laser-desorption-ionization time-of-flight mass spectrophotometry (MALDI-TOF MS)-based assay was developed (called point mutation array, PMA) to identify four major SARS-CoV-2 variants of concern (VOCs) including Alpha, Beta, Delta, and Omicron (namely PMA-ABDO) and differentiate Omicron subvariant (namely PMA-Omicron). PMA-ABDO and PMA-Omicron consist of 24 and 28 mutation sites of the spike gene. Both PMA panels specifically identified VOCs with as low as 10 viral copies/ µl. The panel has shown a 100% concordant with the Next Generation Sequencing (NGS) results testing on 256 clinical specimens with real-time PCR cycle threshold (Ct) values less than 26. It showed a higher sensitivity over NGS; 25/28 samples were positive by PMA but not NGS in the clinical samples with PCR Ct higher than 26. Due to the mass of nucleotide used to differentiate between wild-type and mutation strains, the co-infection or recombination of multiple variants can be determined by the PMA method. This method is flexible in adding a new primer set to identify a new emerging mutation site among the current circulating VOCs and the turnaround time is less than 8 hours. However, the spike gene sequencing or NGS retains the advantage of detecting newly emerged variants.
Democracy, Dictatorship and People’s beliefs: Evidence from the World Value Longitudinal Survey
Authors: Jadhav Vivek
Published: January 2023

The relationship that exists between economic results and political institutions has been the subject of much discussion and debate. Both the nature of political institutions and the economic outcomes have a significant impact on one another. Political institutions have a considerable influence on the outcomes of economic activity, and economic outcome has a big impact on the nature of political institutions. In addition to their effects on the economy, political institutions have the potential to shape the characteristics of social institutions via their impact on the beliefs held by the populace. This research makes use of two different worldwide data sources: World Value Longitudinal Survey and Global State of Democracy Index by International Institute for Democracy and Electoral Assistance in addition to economic data in order to gain an understanding of the differences in the beliefs and values that are held by people living in the various political regimes. There are three key findings from this study. First, as a consequence of the change in political regimes, people's perspectives on the relative merits of equality and freedom tend to change. People with higher incomes place a higher emphasis on freedom than equality under authoritarian leadership more so than those with lower incomes. Second, the available research suggests that people from high income category have a tendency to put less weight on income equality than those who have low income, and this is consistent across various kinds of regimes. Third, in a democratic society, people with lower incomes put a larger value on income equality than those with higher incomes do across all regimes.

Plasma membrane repair defects cause human muscle and heart diseases. In the early stage of membrane repair, TRIM72/MG53 nucleates vesicles to the damaged site within seconds. Despite the therapeutic potential of TRIM72/MG53, the molecular mechanisms are poorly understood. Here, we present the structure of TRIM72, the first complete model of a TRIM E3 ligase. Structure-guided functional analysis revealed a unique phospholipid recognition mode in which a pair of PRYSPRY domains interacts with negatively charged membranes. In subsequent biochemical analyses, the interaction between TRIM72 and the phosphatidylserine-enriched membrane was shown to be critical for both the oligomeric assembly and ubiquitination activity of TRIM72. We elucidated a higher-order model of TRIM72 assembly on the phospholipid bilayer using cryogenic electron tomography followed by subtomogram averaging. We developed a working molecular model of TRIM72 through integrated structural and biochemical techniques. The findings provide a fundamental basis for the study of TRIM E3 ligases, which share a conserved molecular architecture, and provide further insights into the general regulation of RING-type E3 ligases through the cooperation of multiple domains like those in higher-order assemblies.

Em que medida o autoritarismo e o discurso político violento influenciam a intenção de voto e o engajamento em campanha de candidatos de direita? Um experimento de vinhetas
Authors: Gonçalves Clayton Pereira , Ayrosa Eduardo André Teixeira
Published: January 2023

As eleições brasileiras de 2018, 2020 e 2022 foram marcadas por atos (principalmente os de fala) agressivos e violentos vindos dos candidatos e reproduzidos por eleitores. Tais atos frequentemente tinham como objeto atacar o campo ideológico oposto na intenção de conseguir voto e engajamento. Mas será que tais estratégias discursivas são efetivas? Tentando responder essa questão, neste estudo, buscamos analisar em que medida o autoritarismo e o discurso político violento influenciaram a intenção de voto e o engajamento em campanha de candidatos com discurso de direita. Para tanto, foi realizado um experimento com vinhetas entre 273 sujeitos da região metropolitana do Estado do Rio de Janeiro, os quais foram divididos em dois grupos aleatorizados por meio do propensity score matching: um grupo de controle cujo texto remete a um discurso não violento; outro de controle, cujo texto possui tom mais violento. Os resultados apontam que o discurso político violento reduz a intenção de voto, mas, quando mediado pela intenção de voto, o discurso político violento gera maior engajamento na campanha do candidato. Por fim, os resultados indicam que os eleitores com maior grau de autoritarismo tendem a se engajarem mais e terem maior intenção de voto, assim como eleitores com maior o interesse por política tendem a se engajarem mais.

Published: January 2023

Tão rápida quanto a propagação do SARS-CoV-2, as notícias falsas se alastram, de forma exponencial, pelo ambiente virtual, podendo ter consequências devastadoras para a economia, a política e a saúde pública, por exemplo. Este estudo se vale de uma pesquisa de inspiração netnográfica realizada em uma rede social aberta para realizar um mapeamento da rede de atores em torno de uma notícia reconhecidamente falsa sobre a cura da Covid-19. Buscamos, então, a resposta para a seguinte questão: Como ocorre o organizar das redes de fake news por meio de relatos sobre a covid-19? Partindo de uma postagem inicial (P1), que versa sobre uma receita sem comprovação científica acerca de um método de combate à Covid-19, mapeamos os desdobramentos da rede-de-atores humanos e não-humanos em torno da P1. Como resultado, encontramos um engajamento exponencial em torno da notícia falsa, causando uma consequência incalculável para a saúde pública.
Estéticas da existência indie: articulações em torno da concepção do mainstream
Authors: Cavalcanti Rodrigo César Tavares , Souza-Leão André Luiz Maranhão de , Moura Bruno Melo
Published: January 2023

O indie surgiu como experimentações sonoras e criativas que buscavam se afastar do mainstream musical. Essa concepção, aplicada a um gênero musical, pode ser entendida como uma concepção estética. Foucault aponta que a busca por uma estética que legitime a nossa existência é uma prática de constituição do sujeito ético. Por sua vez, fãs de música interagem para discutir, validando ou rejeitando o conteúdo que lhes é direcionado pela indústria musical e os artistas que gostam. A interatividade entre fãs sobre produtos midiáticos os caracteriza como prossumidores, ou seja, consumidores que atuam produtivamente sobre o que consomem. Assim, esta pesquisa se propõe a analisar como as interações prossumeristas de fãs de música indie definem o gênero por meio de uma estética de existência. Para tal, a pesquisa foi realizada por meio de uma netnografia em uma das principais comunidades virtuais de fãs do gênero. Os resultados indicam o exercício de duas estéticas: uma, apresenta o indie como alternativa ao mainstream, forjada nas concepções de liberdade e resistência; outra, atesta o indie como aderente ao mainstream, graças à capacidade de ampliação do acesso ao gênero. Apesar de soarem inconciliáveis, elas se fundam no entendimento de que o indie é belo e que precisa ser preservado a partir de sua relação com a concepção do mainstream.

A silvicultura urbana é considerada um indicador positivo do meio ambiente de uma cidade, pois fornece muitos serviços positivos para as comunidades locais. Porém, nem todos os moradores podem se beneficiar, principalmente em áreas onde as árvores não são de vegetação nativa, como é o caso de Mar del Plata (Argentina). Nesta pesquisa, uma abordagem integrada combinando dados do censo e imagens de satélite mostra que os residentes de uma área residencial arborizada em Mar del Plata com boas condições socioeconômicas se beneficiam com um Índice de Vegetação por Diferença Normalizada (NDVI) mais alto e temperatura mais baixa do que a maioria das partes da cidade.

State repression on the Islamic political opposition in Indonesia in the period of 2017-2021
Authors: Aswar Hasbi , Putri Gustrieni
Published: January 2023

Repressive approach is one of the state's responses to social movements taken to restrain or limit the action of a movement that always strives for a social change process in society. In this context, Hizb ut-Tahrir and the Islamic Defenders Front (Front Pembela Islam – FPI) are two Islamic groups that recently after 2016 have been active in pressuring the government on various political issues. The government responded to these two groups with repressive measures such as stigmatization, criminalization, and dissolving or banning the organization. This study aims to discuss the details of government policies in responding to both HTI and FPI in Indonesia using comparative analysis by collecting secondary data from the media, books, and journals relevant with this study. This study found that the Indonesian government has used various means to repress HTI and FPI, such as intimidation, stigmatization, and disbandment to the organizations.

Parental phubbing is the latest phenomenon that raises concerns because of the changes in habits due to technological developments. It is a form of parental behavior that ignores children as they tend to focus more on activities on gadgets or smartphones. Current parental phubbing studies are limited; however, previous studies have showed the negative impact of parental phubbing on children in late childhood, adolescent, and emerging adulthood, especially on their mental well-being. Therefore, our study aims to determine the impact of parental phubbing on participants’ well-being using a quantitative approach of a comparative independent sample between participants experiencing high and low parental phubbing. The results showed that there were some differences in the effects of parental phubbing on mental well-being, especially mother's parental phubbing (PP-M), for both male and female. In general, parental phubbing affects 3 aspects of mental well-being: a sense of confidence, hope for the future, problem solving and decision-making abilities with a medium effect size. The results indicated that increasingly sophisticated technological developments have affected some changes in behavior and habits through parenting practices, which are not so realized to have negative consequences on the participants’ mental well-being. Our study can also be a reference for new knowledge for practitioners and parents to build an awareness to minimize the further negative impact of parental phubbing behavior on children's development and well-being (in the wide range of developmental stages).

Background

The minority stress model postulates that men who have sex with men (MSM) often encounter multiple stressors because of their sexual minority status, which may lead to psychological problems and maladaptive coping such as addictive behaviors (eg, internet gaming disorder [IGD]). It was hypothesized that hopelessness and loneliness would be associated with IGD via self-control among MSM.

Objective

This study investigated the prevalence of IGD and its associations with variables related to minority stress (loneliness and hopelessness) among MSM who were university students. Mediation involving such associations via self-control was also explored.

Methods

With informed consent, 305 MSM attending universities in Sichuan, China participated in the study. The validated Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition) checklist was used to assess IGD. Multivariable logistic regression adjusted for background factors and structural equation modeling were conducted.

Results

The prevalence of IGD was 12.8% (n=39). Logistic regression found that IGD was positively associated with hopelessness and loneliness, and negatively associated with self-control. The structural equation modeling identified three significant paths between hopelessness/loneliness and IGD: (1) hopelessness → lower self-control → higher IGD (full mediation), (2) loneliness → lower self-control → higher IGD (partial mediation: effect size of 28%), and (3) a direct effect from loneliness to IGD.

Conclusions

IGD was prevalent among young MSM and warrants interventions that may try to reduce the level of psychosocial problems such as loneliness and hopelessness and improve self-control. According to the socioecological model, the promotion of social acceptance and reduction in stigma toward MSM are important in reducing loneliness and hopefulness among MSM. Self-control links up the relationships between psychosocial problems and IGD and should be given special attention. Longitudinal studies are warranted to confirm the findings and test new mediations between loneliness/hopelessness and MSM with IGD.

BACKGROUND

Despite the release of updated metrics for Life’s Essential 8 (LE8), key indicators for assessing cardiovascular health (CVH) status, there is currently no report on their distribution among Chinese children.

OBJECTIVE

This study aimed to assess the nationwide distribution of CVH in Chinese school-aged children using LE8 scores and analyze temporal changes in these scores over time.

METHODS

Participants aged 7 to 19 years from 11 waves (between 1989 and 2018) of the China Health and Nutrition Survey were included in this study. LE8 components were grouped into 2 domains of health behaviors (diet, physical activity, nicotine exposure, sleep) and health factors (BMI, blood lipids, blood glucose, blood pressure). Scores of overall CVH and each LE8 metric were calculated individually. Temporal changes were assessed with joint point regression models by rural and urban living residence. The causal relationships between health behaviors and health factors that changed the most over time were built with cross-lagged panel models.

RESULTS

A total of 21,921 participants, 52.6% (n=11,537) of whom were male, who had data for at least 4 CVH components were included in the analysis. The mean age was 13 (SD 3.6) years. The overall CVH score remained stable in most regions, with the lowest found in Shandong from East China, which had a mean between 67 (SD 10.9) and 67.2 (SD 12.4). In contrast, the highest score was found in Guizhou from Southwest China, with a mean between 71.4 (SD 10.8) and 74.3 (SD 10.3). In rural areas, the diet score decreased significantly from 1997 onward with a speed of 0.18 (95% CI: 0.15-0.21; P<.001) per year, and the BMI score decreased significantly from 2005 onward with a speed of 0.56 (95% CI 0.44-0.68; P<.001) per year. In urban areas, the diet score decreased from 1994 onward with a speed of 0.03 (95% CI: 0.001-0.07; P=.04) per year, and the BMI score decreased from 2002 onward with a speed of 0.63 (95% CI 0.47-0.79; P<.001) per year. The sleep score dropped constantly in both urban and rural areas, with a speed of 0.69 (95% CI 0.58-0.80; P<.001) and 0.69 (95% CI: 0.52-0.86; P<.001) per year, respectively. A decline in the diet score led to a decline in the BMI score with a coefficient of 0.190 (95% CI 0.030-0.351; P=.02), while a decline in the BMI score led to a decline in sleep health with a coefficient of 0.089 (95% CI 0.010-0.168; P=.03).

CONCLUSIONS

Chinese school-aged children and adolescents were generally of moderate CVH status, but mutual influences existed between CVH metrics. Dietary interventions should be prioritized for promoting overall CVH in the future.
How are digital technologies and older adults discussed in times of a global health crisis: A cross-cultural newspaper analysis in Germany and Japan amidst the COVID-19 pandemic (Preprint)
Authors: Jung Marianne , Prochaska-Meyer Isabelle , Schwaninger Isabel
Published: January 2023

BACKGROUND

While the COVID-19 pandemic has caused a digital push in many areas, the inclusion of older adults remains an open challenge. Japan is a super-aged society and often portrayed as more open to digital transformation compared to European societies such as Germany. This provides an opportunity for a cross-cultural understanding of older adults’ representation in newspaper discourse of health(care) and well-being related digital technologies since the outbreak of the pandemic.

OBJECTIVE

Focusing on the health(care) context during the COVID-19 pandemic in Germany and Japan, this paper shows how digital technologies are discussed in newspaper articles. Further, we contribute to a cross-cultural understanding of older adults’ representation in public media in relation to healthcare technologies and COVID-19. Based on our analysis, we present lessons to be learned from Japan in providing recommendations for a more inclusive digital transformation.

METHODS

We analyzed 245 newspaper articles centering on older adults, digital technologies and specifically on health technology from Frankfurter Allgemeine Zeitung (91 articles) and Asahi Shimbun (154 articles), published between March 1st, 2020, and May 31st, 2022. We used qualitative content analysis (QCA) and open-coding techniques in a data driven approach to systematize codes into meaningful categories.

RESULTS

In Germany, the discourse focused on the competitive advantage that digital technologies, such as smartphones, apps, robots, and artificial intelligence offer to the healthcare context, while only a few articles discussed elderly in relation to technology. In Japan, there was a strong representation of older adults both quantitatively and qualitatively. While the German newspaper discourse centered on “the old and the sick'' and older adults’ lack of digital competence, the Japanese discourse covered more diverse perspectives, for example, personal stories of older adults, a specific discussion of their needs, and ways on how to promote their digital literacy. While in Germany the voices of older adults were underrepresented, the dominant message in Japan was: “Don’t forget the elderly”.

CONCLUSIONS

Our recommendations for an inclusive digital society include (1) shifting the discussion of digital transformation to a more holistic way, taking into account not only economic and technical aspects, but also physical, mental and educational barriers that need to be addressed, (2) providing specific ways where all members of the society can participate in digital transformation, for example, via access to education and awareness building, and (3) facilitating a more active role of older adults in the public discourse for an adequate representation of their diverse lived experiences.
