Published: September 2023

AbstractA large number of monitoring sensors are introduced in the power grid. However, the traditional trust models commonly used for edge‐side security management are weak in detecting large‐scale malicious interactions and collusion attacks. For that, a lightweight and anti‐collusion trust model combined with nodes’ dynamic relevance for the power Internet of Things (IoT) is proposed. Firstly, a global trust management system is constructed according to the working mechanism of sensors in the power grid. After that, trust feedback and contact frequency of the devices are combined to build an adaptive dynamic weight vector based on relevance volatility. Fluctuations in trust values are reduced and the trust difference between normal and malicious nodes is widened. An anti‐collusion algorithm based on contact set awareness is also designed to effectively detect collusion attacks. The checksum local broadcast is established in the trust model to counteract the risk of intelligent terminal failure. The results show that the trust model achieves 100% accuracy of node discrimination when the maximum proportion of malicious nodes is 20% in a 50‐node network scale. In addition, the calculation time of the overall model is 211 ms and the memory consumption is 161 kb, which is suitable for power IoT sensor networks.

AbstractThe COVID-19 pandemic underscored the significance of overcoming vaccine adoption resistance and addressing real and perceived barriers for efficient vaccination campaigns. One major problem faced by health systems around the world was that people’s preferences for a specific brand of vaccine often delayed vaccination efforts as people canceled or delayed appointments to receive their preferred brand. Therefore, in the event of another pandemic, it is important to know which factors influence preferences for specific vaccine brands. Previous literature showed that consumers choose products that are congruent with their self-concept, which includes their political affiliation. Given that the discourse around vaccine brands has been strongly politicized during the pandemic, in our work, we test whether partisanship influences preferences for COVID-19 vaccine brands. To test this, we collected survey data from Argentina (N = 432), a country with a clear bi-partisan structure and where a variety of vaccine brands were administered, both from Western and Eastern laboratories. We found that supporters of the ruling party, which had strong ties with Eastern countries such as Russia and China, perceived Eastern vaccine brands (e.g., Sputnik V) to be more effective and safer than Western ones (e.g., Pfizer) whereas the contrary was true for supporters of the opposition. Our results also showed that supporters of the opposing party were more likely to wish to hypothetically switch vaccines, to delay their appointment in case of not receiving their preferred brand, and to disapprove of their local vaccination campaign. Our results demonstrate that political party affiliation biases perceptions of both vaccine brands’ quality and vaccination campaign effectiveness. We anticipate that our results can inform public policy strategies when it comes to an efficient vaccine supply allocation, as political affiliation is a measurable and predictable consumer trait.
A current affair: worker perceptions of noise exposure and occupational hearing loss in Australian coal mines
Authors: Liebenberg Adelle , Oosthuizen Jacques , Reed Sue 
Published: September 2023

Abstract

Background
The objective of the online survey was to determine worker attitudes towards, perceptions on hearing loss, and management of workplace noise; and to identify barriers within current strategies that prevent effective management of hearing health in Australian mines.

Design
This cross-sectional study utilized a modified survey design, initially designed for use by Safe Work Australia for a broader study published in 2010.

Study Sample
The survey questionnaire was made available online to volunteer participants, recruited with the assistance of State and National Health and Safety, and mining organizations. Volunteer participants were required to be proficient in English, be employed by an Australian underground or open cut mine, including coal processing plants; or work as a contractor on one of the specified mine sites. All mining employees, regardless of occupation, job title, and occupational hearing loss classification or status, were invited to complete the questionnaire.

Results
Almost 60% of respondents indicated that they had high noise exposure for than 10 yr or more, and have some trouble hearing, mostly associated with infrequent tinnitus. Nearly 71% of these workers believe that the noise control strategies in their workplaces are effective, but this mostly refers to the use of hearing protection devices.

Conclusion
The results indicate that general knowledge on the cause and effect of noise exposure in the workplace is well understood. However, due to the long latency associated with the development of noise-induced hearing loss (NIHL), there is an issue urgency in terms of risk management. It is surprising that most of the respondents recommended more inspections and administrative controls, especially since most respondents were health, safety, and environment (HSE) professionals. HSE professionals should be advocating for higher order, more permanent solutions, and not purely administrative controls and personal protective equipment. These findings raise the question of whether there is a multifaceted working-culture issue that needs to be addressed, in combination with higher order control implementation.

Abstract

Objective
The primary aim of this paper is to accelerate the number of randomized experimental studies of the reliability and validity in-home tele-neuropsychological testing (tele-np-t).

Method
We conducted a critical review of the tele-neuropsychology literature. We discuss this research in the context of the United States’ public and private healthcare payer systems, including the Centers for Medicare & Medicaid Services (CMS) and Current Procedural Terminology (CPT) coding system’s telehealth lists, and existing disparities in healthcare access.

Results
The number of tele-np publications has been stagnant since the onset of the COVID-19 pandemic. There are less published experimental studies of tele-neuropsychology (tele-np), and particularly in-home tele-np-t, than other tele-np publications. There is strong foundational evidence of the acceptability, feasibility, and reliability of tele-np-t, but relatively few studies of the reliability and validity of in-home tele-np-t using randomization methodology.

Conclusions
More studies of the reliability and validity of in-home tele-np-t using randomization methodology are necessary to support inclusion of tele-np-t codes on the CMS and CPT telehealth lists, and subsequently, the integration and delivery of in-home tele-np-t services across providers and institutions. These actions are needed to maintain equitable reimbursement of in-home tele-np-t services and address the widespread disparities in healthcare access.
Material deprivation and the Brexit referendum: a spatial multilevel analysis of the interplay between individual and regional deprivation
Authors: Haußmann Charlotte , Rüttenauer Tobias 
Published: September 2023

Abstract
In this study, we investigate the relationship between individual and neighbourhood deprivation and the decision to vote for Brexit in the 2016 referendum. Our analysis uses data from the UK Household Longitudinal Study and the English Index of Multiple Deprivation, and employs multilevel models to account for individual-level deprivation, neighbourhood deprivation, and larger-scale regional deprivation. We also examine the interaction between these scales. On average, we find that individual, neighbourhood, and wider area deprivation are associated with a higher likelihood of voting Leave. However, the effect of neighbourhood deprivation is heterogeneous and depends on the broader spatial context: living in deprived neighbourhoods (and to a lesser extent experiencing personal deprivation) has a stronger effect on voting behaviour in more affluent regions. Conversely, the effect of individual and neighbourhood deprivation is close to zero and statistically insignificant in more deprived areas of the country. These results suggest that social comparison processes of in-groups and out-groups operate within larger regional contexts. Our study thus highlights the role of individual and regional deprivation, but also their intersection, in shaping political attitudes and outcomes.

Abstract

Aims
Identifying patients with cardiac sarcoidosis (CS) who are at an increased risk of sudden cardiac death (SCD) poses a clinical challenge. We sought to identify the optimal cutoff for left ventricular ejection fraction (LVEF) in predicting ventricular arrhythmia (VA) and all-cause mortality and to identify clinical and imaging risk factors in patients with known CS.

Methods and results
This retrospective cohort included 273 patients with well-established CS. The primary endpoint was a composite of VA and all-cause mortality. A modified receiver operating curve analysis was utilized to identify the optimal cutoff for LVEF in predicting the primary composite endpoint. Cox proportional hazard regression analysis was used to identify independent risk factors of the outcomes. At median follow-up of 7.9 years, the rate of the primary endpoint was 38% (83 VAs and 32 all-cause deaths). The 5-year overall survival rate was 97%. The optimal cutoff LVEF for the primary composite endpoint was 42% in the entire cohort and in subjects without a history of VA. Younger age, history of VA, lower LVEF, and any presence of scar by cardiac magnetic resonance (CMR) imaging and/or positron emission tomography (PET) were found to be independent risk factors for the primary endpoint and for VA, whereas lower LVEF, baseline NT-proBNP, and any presence of scar were independent risk factor of all-cause mortality.

Conclusion
Among patients with CS, a mild reduction in LVEF of 42% was identified as the optimal cutoff for predicting VA and all-cause mortality. Prior VA and scar by CMR or PET are strong risk factors for future VA and all-cause mortality.

Published: September 2023

Abstract

Background and Objectives
Diabetes is common among Hispanic older adults; however, the association between diabetic complications and pain has not been widely studied in this population. Our objective was to examine the association between diabetes complications and pain over 6 years among Mexican Americans aged 80 years and older.

Research Design and Methods
We used data from Waves 7 to 9 (2010–2016) of the Hispanic Established Population for the Epidemiologic Study of the Elderly (n = 853). Participants were categorized as having no diabetes, diabetes without complications, and diabetes with complications. Pain was defined as reporting pain when standing or walking (pain on weight-bearing) and having pain that limited daily activities (pain interference). We used generalized estimating equations to estimate the odds of pain over 6 years as a function of diabetes status controlling for socioeconomic and health characteristics.

Results
At baseline, the mean age was 85.7 (standard deviation = 3.9) years, 65.2% female, 68.5% had no diabetes, 14.7% had diabetes without complications, and 16.9% had diabetes with complications. Those with diabetes without complications had lower odds of reporting pain on weight-bearing and pain interference, compared to those with no diabetes. Among those reporting diabetes (n = 269), those with complications had higher odds of pain on weight-bearing and pain interference, compared to those without complications. Those with both micro and macro complications had over 2 times the odds of pain, compared to those having no complications.

Discussion and Implications
The lower burden of pain in those with diabetes but no complications may reflect optimal management of diabetes. Routine screening and treatment of pain in patients with diabetes complications can mitigate excess disability and increase the quality of life for patients with diabetes.
Association Between Pain and Fall Worry Among Community-Dwelling Older People With Cognitive Impairment in the United States

Published: September 2023

Abstract

Background and Objectives
Previous studies have found that pain is associated with fall worry among community-dwelling older people. However, both pain and fall worry are poorly understood and underaddressed among community-dwelling older people with cognitive impairment (CI). It is essential to examine the association between pain and fall worry, and how sociodemographic and health characteristics may shape fall worry among this subgroup.

Research Design and Methods
We used data from the 2015 National Health and Aging Trends Study (analytic sample: n = 1150 community-dwelling older people with CI; were self-interviewed; mean age: 81; age range: 65–107). The number of pain sites in the prior month was assessed by presenting a card listing common pain sites (eg, back, knees). Two questions assessed past-month fall worry, “did you worry about falling down” and “did this worry ever limit your activities.” Following descriptive statistics, we fit multinomial logistic regression models to examine the associations between different pain characteristics (number of sites, severity, location) and non-activity-limiting and activity-limiting fall worry.

Results
Non-activity-limiting fall worry was endorsed by 21.1% and activity-limiting fall worry by 13.6% of community-dwelling older people with CI. After adjusting for sociodemographic characteristics and fall-worry-related covariates, multinomial logistic regression analysis found that a greater number of pain sites (relative risk ratio [RRR] = 1.22, 95% Confidence Interval [95% CI] = 1.12–1.33, p &lt;.001) and severe pain (RRR = 2.05, 95% CI = 1.12–3.75, p = .020) was associated with activity-limiting fall worry. Both lower body (knee, foot, and leg) and upper body (hand, wrist, shoulder, neck, and stomach) pain were found to be associated with a high risk of activity-limiting fall worry.

Discussion and Implications
These findings suggest pain and fall worry are common among community-dwelling older people with CI and can be elicited directly from those who are communicative. Fall prevention for this population should prioritize pain management to mitigate activity-limiting fall worry because activity limitation increases the risk of falls.

Abstract

Background and Objectives
Pain treatments and their efficacy have been studied extensively. Yet surprisingly little is known about the types of treatments, and combinations of treatments, that community-dwelling adults use to manage pain, as well as how treatment types are associated with individual characteristics and national-level context. To fill this gap, we evaluated self-reported pain treatment types among community-dwelling adults in the United States and Canada. We also assessed how treatment types correlate with individuals’ pain levels, sociodemographic characteristics, and country of residence, and identified unique clusters of adults in terms of treatment combinations.

Research Design and Methods
We used the 2020 “Recovery and Resilience” United States–Canada general online survey with 2 041 U.S. and 2 072 Canadian community-dwelling adults. Respondents selected up to 10 pain treatment options including medication, physical therapy, exercise, etc., and an open-ended item was available for self-report of any additional treatments. Data were analyzed using descriptive, regression-based, and latent class analyses.

Results
Over-the-counter (OTC) medication was reported most frequently (by 55% of respondents, 95% CI 53%–56%), followed by “just living with pain” (41%, 95% CI 40%–43%) and exercise (40%, 95% CI 38%–41%). The modal response (29%) to the open-ended item was cannabis use. Pain was the most salient correlate, predicting a greater frequency of all pain treatments. Country differences were generally small; a notable exception was alcohol use, which was reported twice as often among U.S. versus Canadian adults. Individuals were grouped into 5 distinct clusters: 2 groups relied predominantly on medication (prescription or OTC), another favored exercise and other self-care approaches, one included adults “just living with” pain, and the cluster with the highest pain levels employed all modalities heavily.

Discussion and Implications
Our findings provide new insights into recent pain treatment strategies among North American adults and identify population subgroups with potentially unmet need for more adaptive and effective pain management.
Autonomous Expansion of Grasshopper Wings Reveals External Forces Contribute to Final Adult Wing Shape
Authors: Salcedo Mary K , Jung Sunghwan , Combes Stacey A 
Published: September 2023

Synopsis
Ecdysis, transformation from juvenile to adult form in insects, is time-consuming and leaves insects vulnerable to predation. For winged insects, the process of wing expansion during ecdysis, unfurling and expanding the wings, is a critical bottleneck in achieving sexual maturity. Internal and external forces play a role in wing expansion. Vigorous abdominal pumping during wing expansion allows insects to pressurize and inflate their wings, filling them with hemolymph. In addition, many insects adopt expansion-specific postures and, if inhibited, do not expand their wings normally, suggesting that external forces such as gravity may play a role. However, two previous studies over 40 years ago, reported that the forewings of swarming locusts can expand autonomously when removed from the emerging insect and laid flat on a saline solution. Termed “autoexpansion,” we replicated previous experiments of autoexpansion on flat liquid media, documenting changes in both wing length and area over time while also focusing on the role of gravity in autoexpansion. Using the North American bird grasshopper Schistocerca americana, we tested four autoexpansion treatments of varying surface tension and hydrophobicity (gravity, deionized water, buffer, and mineral oil) while simultaneously observing and measuring intact, normal wing expansion. Finally, we constructed a simple model of a viscoelastic expanding wing subjected to gravity, to determine whether it could capture aspects of wing expansion. Our data confirmed that wing autoexpansion does occur in S. americana, but autoexpanding wings, especially hindwings, failed to increase to the same final length and area as intact wings. We found that gravity plays an important role in wing expansion, early in the expansion process. Combined with the significant mass increase we documented in intact wings, it suggests that hydraulic pumping of hemolymph into the wings plays an important role in increasing the area of expanding wings, especially in driving expansion of the large, pleated hindwings. Autoexpansion in a non-swarming orthopteran suggests that local cues driving wing autoexpansion may serve a broader purpose, reducing total expansion time and costs by shifting some processes from central to local control. Documenting wing autoexpansion in a widely studied model organism and demonstrating a mathematical model provides a tractable new system for exploring higher level questions about the mechanisms of wing expansion and the implications of autoexpansion, as well as potential bioinspiration for future technologies applicable to micro-air vehicles, space exploration, or medical and prosthetic devices.

AbstractAimsGut bacteria play an important role in poultry nutrition and the immune defense system. Changes in the intestinal microbiome affect the physiological state, metabolism, and innate immunity of poultry. The present study aimed to characterize age-related changes in the gastrointestinal tract microflora in broiler chickens, depending on supplementation of the diet with the in-feed antibiotic Stafac® 110 and a Bacillus subtilis strain-based probiotic.Methods and resultsIn this regard, a comprehensive analysis of the taxonomic structure of the microbial community in the gastrointestinal tract (GIT) of broiler chickens was carried out using a molecular genetic technique of the terminal-restriction fragment length polymorphism analysis and taking into account age dynamics and feeding treatment. A beneficial effect on the microbiological composition and body weight of broilers was observed when using the antibiotic and probiotic in compound feeds. Different bacterial communities were revealed in the duodenum and cecum, and their positive impact on broiler growth was established. The results obtained shed light on the formation of GIT microflora of broiler chickens during the growing period and its changes in response to the use of the antibiotic and the probiotic.ConclusionsWe suggest that the implementation of the tested in-feed antibiotic and probiotic can be beneficial in regulating the intestinal microflora microbiological processes in the GIT and improving the feeding efficiency and productivity of broiler chickens.
