Baseline patient-reported symptom networks and early risk stratification for six-month symptom burden in newly diagnosed glioma
Objective: To characterize the baseline patient-reported symptom network in newly diagnosed glioma and to develop a baseline-only model for predicting high symptom burden at 6 months, with the aim of informing earlier symptom surveillance and risk-stratified supportive care. Methods: In a prospective cohort of 142 adults with histologically confirmed glioma, 15 patient-reported symptoms were rated at baseline using 0-10 numeric rating scales. Bas…
Exploration on the Reform of On-Site Practical Teaching for the Course “Sensors and Detection Technology” —Taking Resistance Sensors (Strain Sensors) as an Example
Impact of Economic Policy Uncertainty on Bank Loan Restructuring
In recent years, there has been significant interest in economic policy uncertainty and its economic consequences. Fluctuations in economic policies can introduce instability into business operations, resulting in elevated credit default risks. It is important to investigate whether Chinese commercial banks take economic policy uncertainty into account and adopt a more diversified loan structure to mitigate the risks associated with policy change…
Association between weekend catch-up sleep and hypertension of the United States population from 2017 to 2020
Moderate weekend catch-up sleep could serve as an effective intervention to mitigate hypertension risk, especially in populations with restricted weekday sleep. These results suggest the potential for integrating sleep management strategies into public health recommendations to address hypertension. Future longitudinal studies are needed to confirm these findings and clarify the mechanisms underlying the relationship between WCS and hypertension …
Exploring how personal experience with wildfire relates to climate change engagement in the western United States
Visualizing Climate Change
This study uses climate change visuals to test to what extent individuals’ threat and efficacy perceptions of climate change interact with their abstract and concrete mind styles to influence their responses to the issue. Findings from online experiments reveal that abstract images intensified the negative effect of threat perceptions on psychological distance as well as the positive effect of vulnerability perception on behavioral intention. Pai…

Background: Exposure to high levels of heavy metals has been widely recognized as an important risk factor for metabolic syndrome (MetS). The main purpose of this study is to assess the associations between the level of heavy metal exposure and Mets using machine learning (ML) method. Methods: The data used in this study are from the national health and nutrition examination survey 2003-2018. According to the demographic information and heavy met…
Status and analysis of undetected plague cases in Yunnan Province, China
Background The virulence of Yersinia pestis strains in the Rattus flavipectus plague focus is relatively low. The purpose of this study was to investigate the undetected, sporadic plague cases in plague foci and provide the basis for plague prevention and control. Methods A 3-year-old plague-confirmed case was investigated in the R. flavipectus plague focus of Yunnan Province in 2020 due to the intensive screening for fever symptoms during the co…
Association between weekday sleep, weekday-weekend sleep duration gap, and hypertension in American adolescents
The study highlighted that insufficient weekday sleep duration significantly increases hypertension risk among adolescents. Contrary to popular belief, compensating for sleep deprivation through extended WWSDG did not mitigate this risk. Public health interventions should focus on promoting consistent and adequate sleep throughout the week for cardiovascular health benefits in adolescents. Further longitudinal research is necessary to explore cau…
Are Covid-19 and climate change competing crises? New evidence on the finite pool of worry and risk-as-feelings hypotheses
The Nexus Between Covid-19 and Climate Change in US Newspapers
Case report
Brucellosis is an important zoonosis and a multisystem disease. The signs and symptoms of brucellosis are not specific. In the clinical, brucellosis is often ignored and misdiagnosed. We report a case of brucellosis who was misdiagnosed as coronavirus disease 2019 (COVID-19)/influenza and received delayed treatment during strict COVID-19 control. The neglect of other diseases due to COVID-19 and empirical diagnosis and treatment by medical staff …
The influence path of community green exposure index on activity behavior under multi-dimensional spatial perception
The purpose of this research is to reveal the internal relationship among community green space, space perception, and activity behavior response to supplement the lack of research results on the binary relationship between green space and behavior. Nine residential community green spaces and 398 residents were selected as the research objects. Thematic clustering and factor identification were used to determine the spatial dimensions of communit…
Protective behaviors against wildfire smoke in the western United States
Serological investigation of plague and brucellosis infection in Marmota himalayana plague foci in the Altun Mountains on the Qinghai-Tibet Plateau
The Altun Mountains are among the most active regions of Marmota himalayana plague foci of the Qinghai-Tibet Plateau where animal plague is prevalent, whereas only three human cases have been found since 1960. Animal husbandry is the main income for the local economy; brucellosis appears sometimes in animals and less often in humans. In this study, a retrospective investigation of plague and brucellosis seroprevalence among humans and animals was…
Understanding the Inequality of Web Traffic and Engagement in Online Healthcare Communities
The online healthcare community (OHC) is a kind of doctor-patient communication platform, in which doctors can share medical knowledge and provide various kinds of counsel for patients. However, if the OHC's web traffic is concentrated on a small number of doctors, or if only a few doctors are actively involved in the OHC's activities, this will not be conducive to the optimal development of the OHC. This study explores this issue of inequality a…
First Case Report of Human Plague Caused by Excavation, Skinning, and Eating of a Hibernating Marmot (Marmota himalayana)
Introduction The Qinghai-Tibet Plateau is considered the most plague-heavy region in China, and skinning and eating marmots ( Marmota himalayana ) are understood to be the main exposure factors to plague. Yersinia pestis is relatively inactive during marmots' hibernation period. However, this case report shows plague infection risk is not reduced but rather increased during the marmot hibernation period if plague exposure is not brought under con…
Refining the Application of Construal Level Theory
Recent studies have found mixed evidence about the role of psychological distance of climate change in people’s engagement with the issue. To gain more clarity in the application of construal level theory of psychological distance in climate change communication, we used two online experiments to investigate how abstract and concrete construals of climate change imagery may differentially influence people’s perceived psychological distances to th…
Animation in Environmental Journalism
An experiment with 413 US participants was conducted to examine the role of animation in environmental journalism. Results show that there was no consistent modality effect (live-action vs. animation) on news perception and information-seeking across environmental topics. Specifically, animation was favored in the communication of fracking. On climate change, concern for the issue moderates the modality’s effect on news perceptions, information-s…
Promoting Concern for Climate Change
This study employs Q methodology to identify responses to wildfire imagery and climate change concern. Using photographs shared on Twitter during California’s 2018 Camp Fire, findings reveal three different perspectives on what images evoked the most concern among individuals: catastrophic destruction, smokescapes, and human or animal suffering. Results also reveal the images that evoke the least concern, such as scenes of aid and support and off…
How Effective Are Concrete and Abstract Climate Change Images? The Moderating Role of Construal Level in Climate Change Visual Communication
Relying on construal-level theory, we experimentally test how the level of concreteness and abstraction of climate change imagery affects climate change responses among a diverse sample of U.S. adults ( N = 448). Results show that concrete visual messaging practices cannot directly lead to increased level of concern or behavioral intentions. Instead, they may backfire for conservatives, less-efficacious people, and people who are low in proenviro…
Abstract or concrete? The effect of climate change images on people’s estimation of egocentric psychological distance
Climate change has been widely perceived as a psychologically distant risk, largely viewed as separated from one’s direct experience. Using construal-level theory, we examined how the level of abstraction and concreteness of climate change imagery affects viewers’ perceived psychological distance of climate change, including spatial, temporal, social, and hypothetical (level of uncertainty) distances. Participants ( n = 402) were randomly assigne…
Climate change in China
Chinese news publications potentially play a crucial role in mitigating global climate change. Presently, the majority of scholars treat the Chinese news media system as one single entity. We expect, however, Chinese party-sponsored and market-oriented newspapers differ in their representation of climate change. Using the conceptual framework of news diversity, we examined how Chinese journalists reported on climate change by examining their use …
Social Support for Water Quality
Many communities, especially minority communities, have to deal with contaminated water supplies. Remediating such risks is usually expensive, so requires action from state and/or federal governments. In turn, this requires political support for provision of a collective good, an altruistic action. We use data from a Mechanical Turk convenience sample to examine the influence of values and beliefs on donations to remediate water quality, using ac…
