Published: November 2022

BackgroundSmartphone addiction has become a social problem that affects the healthy growth of adolescents, and it is frequently reported to be correlated with self-esteem, self-control, and social support among adolescents.MethodsA meta-analysis was conducted by searching the PubMed, Web of Science, Embase, PsycINFO, PsycArticles, China National Knowledge Infrastructure (CNKI), WANFANG DATA, and Chongqing VIP Information Co., Ltd. (VIP) databases. Stata 16.0 was used to analyse the overall effect and test the moderating effect.ResultsFifty-six studies were included, involving a total of 42,300 participants. Adolescents' smartphone addiction had a moderately negative correlation with self-esteem (r = −0.25, 95% CI = −0.29 to −0.22, p &lt; 0.001), a strong negative correlation with self-control (r = −0.48, 95% CI = −0.53 to −0.42, p &lt; 0.001), and a weak negative correlation with social support (r = −0.16, 95% CI = −0.23 to −0.09, p &lt; 0.001). Moderation analysis revealed that the correlation between adolescents' smartphone addiction and self-esteem was strongest when smartphone addiction was measured with the Mobile Phone Addiction Tendency Scale for College Students (MPATS; r = −0.38). The correlation between adolescents' smartphone addiction and self-control was strongest when self-control was measured with the Middle school students' Self-control Ability Questionnaire (MSAQ; r = −0.62). The effect of dissertations on smartphone addiction, self-control, and social support among adolescents was significantly larger than that of journal articles. The correlation between adolescents' smartphone addiction and social support was strongest when smartphone addiction was measured with the Mobile Phone Addiction Index (MPAI; r = −0.24). However, the correlations between adolescents' smartphone addiction and self-esteem, self-control, and social support were not affected by age or gender.ConclusionThere was a strong relationship between smartphone addiction and self-esteem, self-control, and social support among adolescents. In the future, longitudinal research should be carried out to better investigate the dynamic changes in therelationship between smartphone addiction and self-esteem, self-control, and social support.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO/, identifier: CRD42022300061.

ObjectivesWith the attention paid to the early diagnosis of depression, this study tries to use the biological information of speech, combined with deep learning to build a rapid binary-classification model of depression in the elderly who use Mandarin and test its effectiveness.MethodsDemographic information and acoustic data of 56 Mandarin-speaking older adults with major depressive disorder (MDD), diagnosed with the Mini-International Neuropsychiatric Interview (MINI) and the fifth edition of Diagnostic and Statistical Manual of Mental Disorders (DSM-5), and 47 controls was collected. Acoustic data were recorded using different smart phones and analyzed by deep learning model which is developed and tested on independent validation set. The accuracy of the model is shown by the ROC curve.ResultsThe quality of the collected speech affected the accuracy of the model. The initial sensitivity and specificity of the model were respectively 82.14% [95%CI, (70.16–90.00)] and 80.85% [95%CI, (67.64–89.58)].ConclusionThis study provides a new method for rapid identification and diagnosis of depression utilizing deep learning technology. Vocal biomarkers extracted from raw speech signals have high potential for the early diagnosis of depression in older adults.

Published: November 2022

ObjectivesSleep disturbances are associated with both the onset and progression of depressive disorders. It is important to capture day-to-day variability in sleep patterns; irregular sleep is associated with depressive symptoms. We used sleep efficiency, measured with wearable devices, as an objective indicator of daily sleep variability.Materials and methodsThe total sample consists of 100 undergraduate and graduate students, 60% of whom were female. All were divided into three groups (with major depressive disorder, mild depressive symptoms, and controls). Self-report questionnaires were completed at the beginning of the experiment, and sleep efficiency data were collected daily for 2 weeks using wearable devices. We explored whether the mean value of sleep efficiency, and its variability, predicted the severity of depression using dynamic structural equation modeling.ResultsMore marked daily variability in sleep efficiency significantly predicted levels of depression and anxiety, as did the average person-level covariates (longer time in bed, poorer quality of life, lower extraversion, and higher neuroticism).ConclusionLarge swings in day-to-day sleep efficiency and certain clinical characteristics might be associated with depression severity in young adults.

Published: November 2022

BackgroundIntrathecal protein synthesis (ITS) occurs in various central nervous system disorders, but few quantitative studies have focused on ITS for neurosyphilis (NS) in southwestern China. We made a study to quantitatively assess the ITS in patients with NS and to investigate the association between ITS and the stages of NS.MethodsCSF–serum specimen pairs from 142 patients (66 NS and 76 non-NS/syphilis) were collected for routine CSF and serum tests. The NS group was divided into slight and severe subgroups according to the NS stages. Three formulas for the quantitative determination of the intrathecal synthesis were calculated to characterize the specimens, including the Ig index (QIg/Qalb), Ig extended index (Ig_EI), and intrathecally synthesized fraction (IgIF) using the hyperbolic function. The role of QTPPA/QIgG as an antibody index (AI = Q specific Ig/QIgG) was also explored.ResultsSero_TRUST titres (1:16, 1:1-1:256), sero_TPPA titres (1:163840, 1:1280-1:1310720), total protein (MTP), and CSF_Igs (p &lt; 0.05) were found to be significantly elevated in the NS group. Intrathecal Ig synthesis can be identified using all three formulas in the NS group. The pattern of Ig intrathecal synthesis was IgIF-G (48.62%) &gt; IgIF-A = IgIF-M (p &lt; 0.05), with the dominant intrathecal fraction being IgG (median, 48.62%), which was also verified by QIgG&gt; Qalb&gt; QIgM = QIgA. In the slight NS group, the intrathecal fractions of IgM (&gt;0 in 4 out of 20 cases) and IgG (&gt;0 in 16 out of 20) were lower than the intrathecal fractions of IgM (&gt;0 in 19 out of 35 cases) and IgG (&gt;0 in 33 out of 38) in the severe group (p &lt; 0.05). The area under the curve (AUC) of the CSF_TPPA antibody index was 0.867 (0.792, 0.922), with an optimal cutoff point of 0.81, providing a sensitivity of 88.91% and specificity of 84.62%.ConclusionAlthough the intrathecal synthesis pattern is IgG dominant in patients with NS, brain-derived IgM and IgA can also be found. Moreover, intrathecal IgM and IgG were associated with a parenchymatous type of neurosyphilis. Syphilis-specific antibodies are a new potential tool for NS diagnosis.

Published: November 2022

BackgroundAlthough type 2 diabetes mellitus (T2DM) plays a significant role in the association between metabolic dysfunction-associated fatty liver disease (MAFLD) and chronic kidney disease (CKD), how T2DM development and glycemic deterioration affect CKD and its renal function indicators, estimated glomerular filtration rate (eGFR) and urine albumin-to-creatinine ratio (UACR), remains unknown. We aimed to assess the association between MAFLD, along with T2DM, and risk of CKD, and then evaluate the effect of metabolic goal achievement in MAFLD on the risk of CKD.MethodsIn this cross-sectional study, 5,594 participants were included. Multivariate logistic regression and linear regression were used to examine the association between MAFLD with its T2DM status and metabolic goal achievement and risk of CKD, as well as eGFR and UACR.ResultsThe MAFLD group had a higher prevalence of CKD (16.2 vs. 7.6%, P &lt; 0.001) than the non-MAFLD group. MAFLD was independently associated with an increased risk of CKD (odds ratio [OR]: 1.35, 95% CI: 1.09–1.67) and increased eGFR and UACR. Among the three MAFLD subtypes, only the T2DM subtype exhibited significant associations with increased risk of CKD (OR: 2.85, 95% CI: 2.24–3.63), as well as increased eGFR and UACR. Glycemic deterioration in MAFLD was dose-dependently associated with an increased risk of CKD (P-trend &lt; 0.001). Achieved metabolic goals in MAFLD decreased the risk of CKD, eGFR, and UACR; MAFLD with 2 or 3 achieved metabolic goals was not significantly associated with the risk of CKD (OR: 0.81, 95% CI: 0.59–1.12) and albuminuria.ConclusionMAFLD was independently associated with an increased risk of CKD, as well as increased eGFR and UACR. This association is strongly driven by T2DM status. Glycemic deterioration in MAFLD was dose-dependently associated with an increased risk of CKD. Achieved metabolic goals in MAFLD decreased the risk of CKD by reducing the risk of albuminuria.

BackgroundReduced physical function and reduced social networks place older adults with hypertension at high risk for medication-related harm. Medication literacy is one of the preventable factors that affect the success of drug therapy for hypertension. However, little is known about the level of medication literacy and its influencing factors in older adults with hypertension.ObjectiveThe purpose of this study was to investigate the levels of social support and medication literacy, and the association between them in older Chinese adult patients with hypertension.MethodsA total of 362 older adult patients with hypertension were investigated using a demographic characteristics questionnaire, the Chinese Medication Literacy Scale for Hypertensive Patients (C-MLSHP) and the Social Support Rating Scale (SSRS). Pearson correlation analysis, canonical correlation analysis (CCA) and hierarchical linear regression were used to analyse the relationship between social support and medication literacy.ResultsOur results showed that the mean scores for the C-MLSHP and the SSRS for older adult patients with hypertension were 23.89 (SD = 4.66) and 39.22 (SD = 5.53), respectively. The results of the Pearson correlation analysis suggested that the score for social support was positively correlated with the score for medication literacy (r = 0.431, P &lt; 0.01). The results of CCA demonstrate that older adult patients with hypertension who had more subjective (rs = 0.682) and objective support (rs = 0.817) performed better in knowledge (rs = 0.633), skills (rs = 0.631) and behavior literacy (rs = 0.715). Hierarchical linear regression indicated that two dimensions of subjective support (B = 0.252, P &lt; 0.001) and objective support (B = 0.690, P &lt; 0.001) in social support were found to be independent predictors of medication literacy (R2 = 0.335, F = 19.745, P &lt; 0.001).ConclusionSocial support is positively associated with medication literacy in older Chinese adult patients with hypertension. The study highlights the importance of social support in promoting medication literacy among older adult patients with hypertension.

Introduction: With current goals of increased space exploration and travel to Mars, there has been great interest in understanding the long-term effects of high atomic number, high energy (HZE) ion exposure on various organ systems and the immune system. Little is known about late effects on the immune system after HZE exposure. Therefore, our objective was to determine how natural killer (NK) cell populations were affected in geriatric mice that were exposed to HZE particles during middle-age, thereby representing elderly retired astronauts that undertook deep space missions.Methods: 10 month old male CBA/CaJ mice were whole-body irradiated: sham (control); 150-cGy gamma-rays (delivered in 1 fraction); 40-cGy 1-GeV/nu 28Si14+ ions (delivered in 3 fractions); 40-cGy 1-GeV/nu 16O8+ ions (1 fraction); and 40-cGy 1-GeV/nu 16O8+ ions (3 fractions). The mice were sacrificed 1–1.5 yr post-exposure, and the spleens harvested. Splenocyte effector (E) cells were harvested and added to 51Cr-labeled Yac-1 target (T) cells in E:T ratios of 12:1, 25:1, 50:1, and 100:1. NK cytotoxicity was measured with 51Cr release. In addition, 2 million splenocytes were aliquoted and stained with a seven-antibody cocktail, and flow cytometry was used to determine the percentage of NK, B lymphocytes, and T lymphocytes in the splenocyte population.Results: Mice exposed to either a single fraction of 150-cGy gamma rays or 40-cGy 16O8+ ions in 3 fractions were found to have significant decreases in NK cytotoxicity of approximately 30% and 25%, respectively. No significant differences were observed in NK cytotoxicity for 40-cGy 16O8+ ions delivered in 1 fraction, or 40-cGy 28Si14+ ions delivered in 3 fractions. No significant differences were observed in the percentage of spleen cells that were NK (%NK) amongst the groups.Conclusion: Fractionated HZE ion exposure has the potential to affect the innate arm of the immune system long after exposure, leading to decreases in NK cell function. Therefore, protective countermeasures may need to be considered to decrease the risk of reduced long-term immune function in elderly retired astronauts that undertook deep space missions.
Rio, Ruas e Sambas:
Authors: Nigro Fernandes Solis Victor 
Published: November 2022

O presente artigo procura analisar o processo de constituição do Rio de Janeiro enquanto uma cidade musical. Mais precisamente, sua composição no território enquanto uma cidade do Sul Global foi produzida a partir de múltiplos processos sociais ao longo do tempo, engendrando uma sociedade ao mesmo tempo cosmopolita e desigual. O artigo traz a imagem de um caleidoscópio social, representativo de um movimento espontâneo pelo qual a população se misturaria e se relacionaria, entre si e externamente, de modo diverso em fluxos múltiplos ao longo do tempo, tendo em vista que as relações sociais estão em permanente transformação. As iniciativas seriam tomadas por entre as brechas que haviam no interior das políticas repressivas e excludentes sobre os segmentos populares de maioria negra, ou seja, os indivíduos pertencentes a esses estratos participariam da vida social conjunta, coletivamente construindo seus laços sociais, sua identidade em comum, expressando suas concepções de mundo e consolidando-se enquanto grupo social ativo através das manifestações culturais, nas festas, meios musicais e artísticos em geral, ainda que limitados a períodos e ambientes restritos.
A partir de uma metodologia de revisão histórica da formação da cidade e de algumas experiências de atores sociais importantes para o samba, pretendo destacar os espaços de sociabilidade comuns à população, tais como as ruas, avenidas e praças, bem como locais de natureza privada, como as residências e os botequins, os quais, de maneira conflituosa, possibilitariam a construção das redes de sociabilidade interna e a reterritorialização de espaços musicais. Procuro, ainda, apontar como essa coesão interna transbordou para além de grupos sociais restritos a uma esfera local, a partir de intensas relações sociais e da circularidade cultural, espalhando assim a “vocação musical” da cidade do Rio de Janeiro como uma produção moderna exterior ao poder colonial cultural.

O presente ensaio propõe uma análise inicial da iniciativa Promotoras Legais Populares (PLPs), promovida pela Organização Não-Governamental Themis – Gênero, Justiça e Direitos Humanos de Porto Alegre/RS, com enfoque na formação de redes de mulheres promovida pela instituição. Valendo-se dos conceitos de Teoria Ator-Rede (ANT), múltiplas ontologias e redes de comunicação pública, o trabalho realiza uma reflexão teórico-metodológica como embasamento para investigar como os projetos da ONG Themis contribuem para a visibilidade e credibilidade das mulheres participantes, promovendo o acesso e a defesa de direitos, bem como sua participação política. A análise demonstrou que o sistema de Justiça apresenta um formato único para lidar com as múltiplas experiências das cidadãs, e que o rastreamento de redes de comunicação pública pode representar uma ação inicial de pesquisa, visando compreender as possibilidades de combate à violência contra a mulher, bem como fomentar sua participação política em espaços decisórios. Assim, a triangulação entre Teoria Ator-Rede (ANT), múltiplas ontologias e redes de comunicação pública compõe um frutífero campo analítico, considerando a agência de humanos e não-humanos nos processos de cidadania.

Published: November 2022

<p>This study intends to investigate several machine learning algorithms for sales forecasting strategies. A retailer can use this to predict future market demand and adjust its inventory levels accordingly. The accuracy of these predictions will determine whether the retailer profits or suffers losses. In this paper, we worked on the Walmart Sales dataset from Kaggle. It has over 400,000 rows and about 20 columns. After cleaning and performing the necessary feature engineering of the data, we used machine learning algorithms such as eXtreme Gradient Boosting (with and without tuned hyperparameters), Linear Regression, Ridge Regression, Decision Tree Regressor and Random Forest Regressor (with and without tuned hyperparameters). The most effective algorithm out of all the others was XGBoost when the hyperparameters were tuned. This model performs well on sales prediction by utilising less processing power and memory. </p>
RIS-Based Steerable Beamforming Antenna with Near-Field Eigenmode Feeder
Authors: Tiwari Krishan Kumar , Caire Giuseppe 
Published: November 2022

<p>We present a novel, power and hardware efficient, antenna system leveraging the eigenmodes of the over-the-air propagation matrix from an active multi-antenna feeder (AMAF) to a large reflective intelligent surface (RIS), both configured as standard linear arrays and placed in the near field of each other. We demonstrate the flexibility of the proposed architecture by showing that it is capable of generating radiation patterns for multiple applications such as very narrow beams with low side lobes for space-division multiple access communications, wide-angle beams for short range automotive sensing and sectorial beaconing, and monopulse-like patterns for radar angular tracking. A key parameter in our design is the AMAF-RIS distance which must be optimized and it is generally much less than the Rayleigh distance. For a given AMAF aperture, the optimal AMAF-RIS distance increases as a function of the RIS size. The AMAF-RIS loss is compensated almost exactly by the larger aperture gain of the RIS leading to almost constant RIS gain with increasing RIS sizes. This allows to choose different beam angular selectivities with the same center beam gain. Active RF amplification is done at the AMAF only, thus resulting in a much higher power efficiency and much lower hardware complexity than conventional phased arrays with same beamforming performance.</p>
