Authors: Kim Minhoe , Seo Ji Won , Yun Seokho , Kim Minchul 
Published: September 2023

ObjectiveIt is well known that altered functional connectivity is a robust neuroimaging marker of schizophrenia. However, there is inconsistency in the direction of alterations, i.e., increased or decreased connectivity. In this study, we aimed to determine the direction of the connectivity alteration associated with schizophrenia using a multivariate, data-driven approach.MethodsResting-state functional magnetic resonance imaging data were acquired from 109 individuals with schizophrenia and 120 controls across two openly available datasets. A whole-brain resting-state functional connectivity (rsFC) matrix was computed for each individual. A modified connectome-based predictive model (CPM) with a support vector machine (SVM) was used to classify patients and controls. We conducted a series of multivariate classification analyses using three different feature sets, increased, decreased, and both increased and decreased rsFC.ResultsFor both datasets, combining information from both increased and decreased rsFC substantially improved prediction accuracy (Dataset 1: accuracy = 70.2%, permutation p = 0.001; Dataset 2: accuracy = 64.4%, permutation p = 0.003). When tested across datasets, the prediction model using decreased rsFC performed best. The identified predictive features of decreased rsFC were distributed mostly in the motor network for both datasets.ConclusionThese findings suggest that bidirectional alterations in rsFC are distributed in schizophrenia patients, with the pattern of decreased rsFC being more similar across different populations.

Background/objectiveThe outbreak of COVID-19 in China since 2019 has had a significant impact on the mental health of people in Hubei Province during the three-year pandemic period. Therefore, studying the prevalence of depression among the population of Hubei Province since the pandemic is of great significance.MethodsBased on opportunity and stress theory, we collected provincial-level data from Hubei (N = 3,285) to examine the impact of declining economic status on depressive symptoms and to investigate the moderating effect of psychological resilience during the period of economic adjustment.ResultsWe used propensity score matching to estimate the treatment effect of economic status decline on depression severity and confirmed the moderating effect of psychological resilience. We found that the more that an individual’s economic status declines, the more severe that his or her depressive symptoms become. Specifically, each unit decrease in economic status is associated with an increase of approximately 0.117 units in depression level. In addition, our results indicated that psychological resilience significantly moderated the relationship between economic decline and depression (−0.184*).Conclusions and implicationsOur study confirms the role of economic status in depressive symptoms. Compared with traditional research on the relationship between economic status and mental illness, this paper expands the research regarding the two in the context of a major public health emergency. Furthermore, we suggest ways to improve people’s mental health following the pandemic.

ObjectiveNight flights might aggravate sleep disorders among aging airline pilots, posing a threat to flight safety. In this study, we assess the prevalence of sleep disorders as well as the combined effects of night flight duration and aging on sleep disorders.MethodA cross-sectional study was conducted between July and December, 2021. Participants were recruited from a commercial airline. Sleep disorders were evaluated using the Pittsburgh Sleep Quality Index (PSQI). The interaction effect of night flight duration and age on sleep disorders and their correlates were examined using logistic regression models.ResultsIn total, 1,208 male airline pilots were included in the study, with a median age of 34 (interquartile range [IQR]: 29–39) years. The overall prevalence of sleep disorders was 42.6%. The multivariate logistic regression identified an interaction between night flight duration and age on sleep disorders (adjusted odds ratio [aOR] of the interaction term was 5.85 95% CI: 2.23–15.34 for age ≥ 45 years; 1.96 95% CI:1.01–3.81 for the age group 30–44 years). Longer night flight duration (aOR: 4.55; 95%CI: 1.82–11.38) and body mass index (BMI) ≥28.0 kg/m2 (aOR: 0.16; 95% CI: 0.03–0.91) were significantly associated with sleep disorders in participants aged ≥45 years. Hyperuricemia (aOR: 1.54; 95% CI: 1.09–2.16) and regular exercise (aOR: 0.23; 95% CI: 0.08–0.70) were significantly associated with sleep disorders in the 30–44 years age group.ConclusionThe mean monthly night flight duration and aging had a synergistic effect on airline pilots’ sleep disorders, implying an aging and work-related mechanistic pathogenesis of sleep disorders in airline pilots that requires additional exploration and intervention.

Salinity influences the level of antioxidants and proline content, which are both involved in the regulation of stress responses in plants. To examine the interplay between the antioxidant system and proline metabolism in plant stress acclimation, explants of Lycium ruthenicum were subjected to NaCl treatments, and the growth characteristics, antioxidant enzyme activities, proline accumulation, and metabolic enzyme content were analyzed. The results revealed that NaCl concentrations between 50 to 150 mM have a positive effect on the growth of L. ruthenicum explants. Increasing NaCl concentrations elevated the activities of superoxide dismutase (SOD) and catalase (CAT), while hydrogen peroxide (H2O2) content was inhibited, suggesting that the elevated antioxidants play a central protective role in superoxide anion (O2•−) and H2O2 scavenging processes in response to NaCl treatments. Also, high proline levels also protect antioxidant enzyme machinery, thus protecting the plants from oxidative damage and enhancing osmotic adjustment. Increasing levels of pyrroline-5-carboxylate synthetase (P5CS), pyrroline-5-carboxylate reductase (P5CR), and ornithine-δ-aminotransferase (δ-OAT) were observed, resulting in elevated level of proline. In addition, the expression levels of LrP5CS1, -2, -3, LrOAT-1, and -2 were promoted in NaCl treatments. According to the combined analysis of metabolic enzyme activities and their relative expression, it is confirmed that the glutamate (Glu) pathway is activated in L. ruthenicum faced with different levels of NaCl concentrations. However, Glu supplied by δ-OAT is fed back into the main pathway for proline metabolism.

CMI-Net: a Unified Framework for Physiological Time Series Classification with Incomplete Modalities
Authors: Shen Qi 
Published: September 2023

<p>In recent years, health assessment and aided diagnosis based on physiological time series (PTSs) have become a research hotspot. To achieve reliable assessment and diagnosis, multimodal PTSs are excellent choices for manipulation in deep learning pipelines. However, existing methods are not effective in solving the problem of missing modalities. In addition, the exploration of temporal information within PTSs is also a serious challenge. To this end, we propose a unified framework, named contrastive modal imagination network (CMI-Net), for the PTSs classification with incomplete modalities. Specifically, CMI-Net handles the problem of arbitrary modal missing through the combination of modal awareness imagination module (MAIM) and semantic & modal calibration contrastive learning (SMCCL). Among them, MAIM can capture the interaction among modalities by learning the shared representation distribution of all modalities. Meanwhile, SMCCL introduces prior information of semantics and modality to check semantic consistency while maintaining the uniqueness of each modality. Utilizing the calibration of SMCCL, the data distribution recovered by MAIM is aligned with the real data distribution. We further design a novel context-aware architecture, which can learn the intra- and inter-segment temporal dependencies of PTSs and facilitate the mining of cross-scale temporal context information. To the best of our knowledge, this is one of the ﬁrst works to formally study the multimodal missing problem in PTSs. Extensive experiments on four real-world multimodal PTSs datasets demonstrate that CMI-Net remarkably outperforms other competitive methods. </p>

Published: September 2023

Introdução: Existem redes de cooperação internacional compostas por instituições de segurança pública para promoção, prevenção e repressão de crimes transnacionais organizados, as quais precisam de alguns fatores para que funcionem adequadamente. Objetivo: Analisar a percepção de confiabilidade dos adidos da Polícia Federal no compartilhamento de informações com os atores das instituições congêneres internacionais, em apoio às investigações de crimes. Métodos: A pesquisa é caracterizada como descritiva, transversal com abordagem qualitativa. Por amostragem censitária, foram realizadas entrevistas virtuais com adidos da Polícia Federal de 16 países, com apoio de roteiro semiestruturado. Os dados foram transcritos e submetidos à análise de conteúdo, sendo que algumas categorias foram estabelecidas a priori e outras a posteriori. Resultados: A percepção de confiabilidade da contraparte só é realizada quando a informação é classificada como sensível, e é suprimida quando a instituição tem boa reputação. Percebeu-se extrema relevância da presença física do adido, principalmente nas interações com atores confiáveis de instituições cuja reputação é negativa. Constatou-se a variação nos critérios de análise da percepção de confiabilidade adotadas pelos adidos referentes a competência, integridade e benevolência, sendo que a integridade foi o critério priorizado pela moda. Conclusões: A percepção de confiabilidade dos adidos influencia as investigações de crimes, pelo incremento da disposição para compartilhar informações da contraparte e fomento a disponibilidade e qualidade destas. A abordagem qualitativa contribuiu para o aprofundamento da análise de percepção sobre a relação de confiabildiade e compartilhamento de informações, pois permitiu detalhamento e exemplificação de casos que subsidiaram a criação de categorias temáticas.
