Exposure to climate change information predicts public support for solar geoengineering in Singapore and the United States.

Solar geoengineering is a controversial climate policy measure that could lower global temperature by increasing the amount of light reflected by the Earth. As scientists and policymakers increasingly consider this idea, an understanding of the level and drivers of public support for its research and potential deployment will be key. This study focuses on the role of climate change information in public support for research and deployment of stratospheric aerosol injection (SAI) in Singapore (n = 503) and the United States (n = 505).

Balancing climate resilience and adaptation for Caribbean Small Island Developing States (SIDS): Building institutional capacity.

Although the Caribbean's Small Island Developing States (SIDS) minimally contribute to global greenhouse gas emissions, they face disproportionate climate risks and are particularly susceptible to systemic economic threats posed by climate change and subsequent increases in climate variability. Historically, strategic programs and investments have sought to develop more robust and adaptive engineered systems to absorb climate threats. However, such initiatives are limited and under-resourced in the SIDS' context.

Barriers to responsible innovation of nanotechnology applications in food and agriculture: A study of US experts and developers.

The use of nanotechnology and engineered nanomaterials in food and agriculture (nano-agrifood) sectors is intended to provide several potential benefits to consumers and society, such as the provision of more nutritious processed foods, edible food coatings to extend shelf lives of fresh cut produce, and more sustainable alternatives to traditional agrochemicals. The responsible innovation of nano-agrifoods may be particularly important to pursue given previous case studies involving other agrifood technologies that experienced significant public consternation. Here, we define responsible innovation following Stilgoej et al.

Responsible innovation of nano-agrifoods: Insights and views from U.S. stakeholders.

This paper aims to fill this research gap by investigating views of nano-agrifoods, how well their development adheres to principles of responsible innovation, and potential challenges for achieving responsible nano-agrifood innovation. Using an online engagement platform, we find that U.

Influence of rapid COVID-19 vaccine development on vaccine hesitancy.

Introduction: In the race to deploy vaccines to prevent COVID-19, there is a need to understand factors influencing vaccine hesitancy. Secondary risk theory is a useful framework to explain this, accounting for concerns about vaccine efficacy and safety.

Methods: During the first week of July, 2020, participants (N = 216) evaluated one of three different hypothetical vaccine scenarios describing an FDA-approved vaccine becoming available "next week," "in one year," or "in two years.

Can Comorbidity Data Explain Cross-State and Cross-National Difference in COVID-19 Death Rates?

Many efforts to predict the impact of COVID-19 on hospitalization, intensive care unit (ICU) utilization, and mortality rely on age and comorbidities. These predictions are foundational to learning, policymaking, and planning for the pandemic, and therefore understanding the relationship between age, comorbidities, and health outcomes is critical to assessing and managing public health risks. From a US government database of 1.

COVID-19: how a self-monitoring checklist can empower early intervention and slow disease progression.

The SARS-CoV-2 novel coronavirus pandemic has revealed many scientific, social, and institutional challenges required to improve the health and wellbeing of individuals stricken by this disease. While organizations and governing institutions have risen to the task to concurrently prepare for and respond to this pandemic under conditions of high uncertainty and extreme pressure, another important aspect of this viral infection deserves attention and is not being fully considered, that is early intervention strategies and structured tools for individuals who test positive for the virus and begin developing symptoms. For those whose infection is progressing, we describe the potential benefits of a self-monitoring tool for use in combination with physician directed early medical interventions to slow COVID-19 progression.

Secondary Risk Theory: Validation of a Novel Model of Protection Motivation.

Protection motivation theory states individuals conduct threat and coping appraisals when deciding how to respond to perceived risks. However, that model does not adequately explain today's risk culture, where engaging in recommended behaviors may create a separate set of real or perceived secondary risks. We argue for and then demonstrate the need for a new model accounting for a secondary threat appraisal, which we call secondary risk theory.

A typology of beliefs and misperceptions about the influenza disease and vaccine among older adults in Singapore.

Access to the influenza vaccine pose little barriers in developed countries such as Singapore and vaccination against influenza is highly recommended for at-risk populations including older adults. However, vaccination rates are much lower than recommended despite the significant morbidity and mortality associated with the disease among this vulnerable population. Given timely goals to increase vaccine acceptance and uptake, we explored Singaporean older adults' misperceptions about influenza disease and vaccine.

"Influenza" versus "Flu": Do Different Medical Terms Affect Vaccination Intention?

Confusion about disease terminology contributes to lower risk perceptions that may lead to lesser engagement in protective measures. Communication campaigns promoting influenza vaccination have become commonplace around the world. Such campaigns vary widely in their terminology used from depicting the disease and response formally as an "influenza vaccination" to more colloquial terms like "flu shot.

Herpesvirus Infections of the Nervous System.

Purpose Of Review: This article reviews the spectrum of neurologic disease associated with human herpesvirus infections.

Recent Findings: As more patients are becoming therapeutically immunosuppressed, human herpesvirus infections are increasingly common. Historically, infections with human herpesviruses were described as temporal lobe encephalitis caused by herpes simplex virus type 1 or type 2.

Genetic susceptibility to cerebrovascular disease: A systematic review.

Investigation of genetic susceptibility to cerebrovascular disease has been of growing interest. A systematic review of human studies assessing neurogenomic aspects of cerebrovascular disease was performed according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement. Any association study exploring genetic variants located in the exome associated with one of the major cerebrovascular diseases with at least 500 subjects was eligible for inclusion.

Synthetic biology (SB) applies engineering principles to biology for the construction of novel biological systems designed for useful purposes. From an oversight perspective, SB products come with significant uncertainty. Yet there is a need to anticipate and prepare for SB applications before deployment.

Collateral flow and brain changes on computed tomography angiography predict infarct volume on early diffusion-weighted imaging.

Background: We investigated whether a computed tomography (CT)-based score could predict a large infarct (≥ 80 mL) on early diffusion-weighted magnetic resonance imaging (DWI).

Methods: Acute stroke patients considered for endovascular therapy within 8 hours of the onset of symptoms were included. The Alberta Stroke Program Early Computed Tomography Score (ASPECTS) was determined on noncontrast CT and computed tomography angiography source images (CTA-SI).

Diffusion-weighted imaging volume as the best predictor of the diffusion-perfusion mismatch in acute stroke patients within 8 hours of onset.

Background: Diagnostic accuracies of standard NCCT, CTA, CTA-SI, FLAIR, and DWI to detect the diffusion-perfusion mismatch (DPM) were compared.

Methods: Stroke patients considered for endovascular therapy within 8 hours of onset were enrolled. DPM was defined as at least 160% mismatch between DWI and PWI volume.

Centenarian middle cerebral artery occlusion treated with intra-arterial mechanical embolectomy.

Advanced age, arbitrarily defined as over 80 years, has been an exclusion criterion in many clinical trials for the treatment of acute ischemic stroke. The oldest person, to our knowledge, treated for acute ischemic stroke with intra-arterial therapy is presented and, importantly, this patient was excluded from intravenous tissue plasminogen activator due to an advanced age of 100 years and arrival in our emergency department within the 3-4.5 h time window.

Properties of engineered vascular constructs made from collagen, fibrin, and collagen-fibrin mixtures.

Vascular constructs were formed by embedding rat aortic smooth muscle cells in three-dimensional matrices of Type I collagen, fibrin, or a mixture of collagen and fibrin in a 1:1 ratio, at total matrix protein concentrations of 2 and 4 mg/ml. Morphological and mechanical properties were evaluated after 6 days in culture, and the effect of cyclic mechanical strain on collagen-fibrin mixture constructs was also studied. Constructs made with the lower protein concentration compacted to the greatest degree, and fibrin was found to enhance gel compaction.
