The education of mental health nurses has long remained a contentious topic in the UK and internationally. This research seeks to gather the perspectives of those directly affected by mental health nurse education. To investigate what knowledge, skills and values current mental health nursing students, graduate mental health nurses and people with lived experience of accessing mental health services believe should be paramount within pre‐registration education. Data was gathered through focus groups involving a mix of pre‐ and post‐qualified mental health nurses and people with lived experience of accessing mental health services. Data was collected through audio recordings, which were transcribed and subjected to thematic analysis. The analysis generated four themes of: (i) Values and ethics‐based education, (ii) Self‐awareness, (iii) Understanding and therapeutically being with others and (iv) Specialism versus Genericism. The findings speak to the special nature of mental health nursing and the need for students to develop specialist mental health knowledge and skills, alongside self‐knowledge. The findings provide a unique insight into the aspects of pre‐registration nursing felt to be most valuable by the three participant groups in this study. The findings reiterate the importance nurse education celebrating the specialism of mental health nursing and adds to the growing weight of literature for increased specialism with future education standard reviews.

This paper describes the use of a highly crystalline conductive 2D copper3(hexaiminobenzene)2 (Cu3(HIB)2) as an ultrasensitive (limit of detection of 1.8 part‐per‐billion), highly selective, reversible, and low power chemiresistive sensor for nitric oxide (NO) at room temperature. The Cu3(HIB)2‐based sensors retain their sensing performance in the presence of humidity, and exhibit strong signal enhancement towards NO over other highly toxic reactive gases, such as NO2, H2S, SO2, NH3, CO, as well as CO2. Mechanistic investigations of the Cu3(HIB)2‐NO interaction through spectroscopic analyses and density functional theory revealed that the Cu‐bis(iminobenzosemiquinoid) moieties serve as the binding sites for NO sensing, while the Ni‐bis(iminobenzosemiquinoid) MOF analog shows no noticeable response to NO. Overall, these findings provide a significant advance in the development of crystalline metal‐bis(iminobenzosemiquinoid)‐based conductive 2D MOFs as highly sensitive, selective, and reversible sensing materials for the low‐power detection of toxic gases.

Large language models are increasingly used in educational and psychological measurement activities. Their rapidly evolving sophistication and ability to detect language semantics make them viable tools to supplement subject matter experts and their reviews of large amounts of text statements, such as educational content standards. This paper presents an application of text embeddings to find relationhips between different sets of educational content standards in a content mapping process. Content mapping is routinely used by state education agencies and is often a requirement of the United States Department of Education peer review process. We discuss the educational measurement problem, propose a formal methodology, demonstrate an application of our proposed approach, and provide measures of its accuracy and potential to support real‐world activities.

Sarcoptic mange is a debilitating disease affecting free‐living/wild bare‐nosed wombats (Vombatus ursinus). The disease causes thickening of the skin, pruritus, alopecia and deep fissures in the skin of infected animals, and ultimately death if left untreated. In Australia, there are approvals from the Australian Pesticides and Veterinary Medicines Authority to use moxidectin for treating sarcoptic mange in bare‐nosed wombats; however, few published literatures document the success of treatment regimens. Two adult male bare‐nosed wombats presented with dermatitis, erythema and crusting of the skin. Evaluation of skin scrapings confirmed the presence of live Sarcoptes scabiei. Both wombats were treated with three 100‐mL doses of moxidectin topically poured on to the dorsal backline approximately 7 days apart. Both animals showed improvement, with skin becoming clear of crusting and dermatitis, and no S. scabiei mites were present on either animal after 2 weeks. Here, we presented two clinical scenarios of sarcoptic mange in wombats that were successfully treated with three 100‐mL doses of moxidectin applied topically. We recommend this treatment be used where wombats can be identified and monitored throughout their recovery. [ABSTRACT FROM AUTHOR]

Summary: Mesophyll conductance (gm) describes the ease with which CO2 passes from the sub‐stomatal cavities of the leaf to the primary carboxylase of photosynthesis, Rubisco. Increasing gm is suggested as a means to engineer increases in photosynthesis by increasing [CO2] at Rubisco, inhibiting oxygenation and accelerating carboxylation. Here, tobacco was transgenically up‐regulated with Arabidopsis Cotton Golgi‐related 3 (CGR3), a gene controlling methylesterification of pectin, as a strategy to increase CO2 diffusion across the cell wall and thereby increase gm. Across three independent events in tobacco strongly expressing AtCGR3, mesophyll cell wall thickness was decreased by 7%–13%, wall porosity increased by 75% and gm measured by carbon isotope discrimination increased by 28%. Importantly, field‐grown plants showed an average 8% increase in leaf photosynthetic CO2 uptake. Up‐regulating CGR3 provides a new strategy for increasing gm in dicotyledonous crops, leading to higher CO2 assimilation and a potential means to sustainable crop yield improvement.

Record high temperatures were documented in the McMurdo Dry Valleys, Antarctica, on 18 March 2022, exceeding average temperatures for that day by nearly 30°C. Satellite imagery and stream gage measurements indicate that surface wetting coincided with this warming more than 2 months after peak summer thaw and likely exceeded thresholds for rehydration and activation of resident organisms that typically survive the cold and dry conditions of the polar fall in a freeze‐dried state. This weather event is notable in both the timing and magnitude of the warming and wetting when temperatures exceeded 0°C at a time when biological communities and streams have typically entered a persistent frozen state. Such events may be a harbinger of future climate conditions characterized by warmer temperatures and greater thaw in this region of Antarctica, which could influence the distribution, activity, and abundance of sentinel taxa. Here we describe the ecosystem responses to this weather anomaly reporting on meteorological and hydrological measurements across the region and on later biological observations from Canada Stream, one of the most diverse and productive ecosystems within the McMurdo Dry Valleys. Plain Language Summary: An atmospheric river event in March 2022 led to record warm temperatures over much of Antarctica. Here we report the ecological and hydrological responses to these extraordinary temperatures. The McMurdo Dry Valleys are unique among other regions of Antarctica that experienced this extreme weather event because contemporary observations of ecosystem responses to unseasonable weather can be anchored to a 30‐year record of meteorology, stream flow, and soil community data supported by the National Science Foundation Long Term Ecological Research program. As such weather anomalies are expected to be more common in future Antarctic climate regimes our insights are broadly relevant to the scientific community seeking to predict future ecosystem and organismal responses to ongoing climate change. Key Points: An atmospheric river caused extreme weather in the Antarctic Dry Valleys in March 2022 with temperatures 25°C above average conditionsRecord fall temperatures drove mobilization of liquid water and reactivation of biota at a time when organisms are entering winter dormancyBiotic responses to unseasonable warm and wet conditions may influence diversity and life‐history characteristics of biotic communities [ABSTRACT FROM AUTHOR]

Aims: To describe the range of effects experienced due to the drinking of people respondents know and analyze risk and protective factors for harm from the drinking of partners and household members, other relatives and friends and co‐workers. Design, setting and participants: Surveys of 2574 participants' experiences were obtained from two samples: 1000 people responded to random digitally dialled Australian mobile calls and 1574 participants responded from the Life in AustraliaTM panel survey. Measurements: Respondents were asked whether they had been negatively affected in the previous 12 months by the drinking of persons they knew who were 'a heavy drinker or drank a lot sometimes' and the nature of these harms. Weighted logistic regressions were used to analyze differences in rates of key negative outcomes from known others' drinking by gender, age and socio‐economic status. Findings Almost two thirds [60.2%; 95% confidence interval (CI) = 57.7%–62.7%] of participants reported having heavy drinkers in their lives and 21.8% (95% CI = 19.8%–23.9%) reported being negatively affected by the drinking of people they knew well in some way. Participants reported a gamut of effects, including, most commonly, adverse social effects: having to transport relatives and friends who had been drinking, role failure and faults, being emotionally hurt or neglected, serious arguments, family problems, having to care for drinkers and verbal abuse. Less commonly, respondents reported physical or sexual harm, property damage, financial stress and threats from others' drinking. Women (odds ratio = 1.49; 95% CI = 1.13–1.95), younger people, rural, Australian‐born (vs. respondents born overseas in non‐English speaking countries) and more frequent drinkers were more likely to report harm from a drinker they knew than their counterparts after adjusting for other variables in the model. Conclusions: Australians appear to be commonly adversely affected by the drinking of people they know. Harms from known drinkers are more likely to be experienced by women than men, particularly from the people they live with and other relatives. [ABSTRACT FROM AUTHOR]

Computer adaptive testing (CAT) is an increasingly common mode of test administration offering improved test security, better measurement precision, and the potential for shorter testing experiences. This article presents a new item selection algorithm based on a generalized objective function to support multiple types of testing conditions and principled assessment design. The generalized nature of the algorithm permits a wide array of test requirements allowing experts to define what to measure and how to measure it and the algorithm is simply a means to an end to support better construct representation. This work also emphasizes the computational algorithm and its ability to scale to support faster computing and better cost‐containment in real‐world applications than other CAT algorithms. We make a significant effort to consolidate all information needed to build and scale the algorithm so that expert psychometricians and software developers can use this document as a self‐contained resource and specification document to build and deploy an operational CAT platform.

INTRODUCTION: Recruitment challenges in people with and without Down syndrome (DS) can delay research progress and risk sample bias. This study identified and quantified differences in research attitudes across populations of research enrollment decision‐makers for individuals with and without DS. METHODS: We performed analyses using data from two registries: the University of California, Irvine Consent‐to‐Contact (C2C) Registry and DS‐Connect. The former represented a sample of non‐DS decision‐makers (N = 4818), while for the latter, we excluded individuals with DS, leaving a population of DS family decision‐makers (N = 976). We assessed scores on the Research Attitudes Questionnaire (RAQ) between DS and non‐DS decision‐makers. We compared total RAQ scores using linear regression and assessed item‐level RAQ differences using proportional odds regression. RESULTS: Mean total RAQ scores were not statistically different between decision‐makers in the two registries, after adjusting for age, sex, race and ethnicity, education, and the coronavirus disease 2019 (COVID‐19) time frame (Est. Diff = 0.11, 95% confidence interval [CI]: ‐0.22, 0.43; p = 0.531). However, in a pre‐specified analysis, we did find evidence of differential attitudes on item‐level RAQ scores. Specifically, decision‐makers for participants with DS had increased odds of a more favorable response to the question of responsibility to help others (DS vs. non‐DS: odds ratio [OR] = 1.26, 95% CI: 1.08, 1.48) and decreased odds of a more favorable response to the question regarding the belief that medical research would find cures for major diseases during their lifetime (DS vs. non‐DS: OR = 0.77, 95% CI: 0.66, 0.90). DISCUSSION: Our findings provide insights for researchers to develop strategies for recruiting individuals with and without DS into clinical research. The observed item‐level differences warrant further investigation to instruct precise recruitment strategies. Highlights: Research attitudes between decision‐makers for individuals with Down syndrome (DS) and decision‐makers without DS were observed to be similar on average.Item‐level differences in research attitudes were observed to differ for DS and non‐DS decision‐makers.These results can help facilitate precise recruitment strategies for populations with DS.

The rising costs of cancer care and subsequent medical financial hardship for cancer survivors and families are well documented in the United States. Less attention has been paid to employment disruptions and loss of household income after a cancer diagnosis and during treatment, potentially resulting in lasting financial hardship, particularly for working‐age adults not yet age‐eligible for Medicare coverage and their families. In this article, the authors use a composite patient case to illustrate the adverse consequences of cancer diagnosis and treatment for employment, health insurance coverage, household income, and other aspects of financial hardship. They summarize existing research and provide nationally representative estimates of multiple aspects of financial hardship and health insurance coverage, benefit design, and employee benefits, such as paid sick leave, among working‐age adults with a history of cancer and compare them with estimates among working‐age adults without a history of cancer from the most recently available years of the National Health Interview Survey (2019–2021). Then, the authors identify opportunities for addressing employment and health insurance coverage challenges at multiple levels, including federal, state, and local policies; employers; cancer care delivery organizations; and nonprofit organizations. These efforts, when informed by research to identify best practices, can potentially help mitigate the financial hardship associated with cancer. [ABSTRACT FROM AUTHOR]

Parkinson's disease (PD) is characterised by progressive loss of dopaminergic (DA) neurons from the substantia nigra (SN) and α‐synuclein (αSyn) accumulation. Age is the biggest risk factor for PD and may create a vulnerable pre‐parkinsonian state, but the drivers of this association are unclear. It is known that ageing increases αSyn expression in DA neurons and that this may alter molecular processes that are central to maintaining nigrostriatal integrity. To model this, adult female Sprague–Dawley rats received a unilateral intranigral injection of adeno‐associated viral (AAV) vector carrying wild‐type human αSyn (AAV‐αSyn) or control vector (AAV‐Null). AAV‐αSyn induced no detrimental effects on motor behaviour, but there was expression of human wild‐type αSyn throughout the midbrain and ipsilateral striatum at 20 weeks post‐surgery. Microarray analysis revealed that the gene most‐upregulated in the ipsilateral SN of the AAV‐αSyn group was the SKI Family Transcriptional Corepressor 1 (SKOR1). Bioenergetic state analysis of mitochondrial function found that SKOR1 overexpression reduced the maximum rate of cellular respiration in SH‐SY5Y cells. Furthermore, experiments in SH‐SY5Y cells revealed that SKOR1 overexpression impaired neurite growth to the same extent as αSyn, and inhibited BMP‐SMAD‐dependent transcription, a pathway that promotes DA neuronal survival and growth. Given the normal influence of ageing on DA neuron loss in human SN, the extent of αSyn‐induced SKOR1 expression may influence whether an individual undergoes normal nigrostriatal ageing or reaches a threshold for prodromal PD. This provides new insight into mechanisms through which ageing‐related increases in αSyn may influence molecular mechanisms important for the maintenance of neuronal integrity. [ABSTRACT FROM AUTHOR]

Objective: New‐onset refractory status epilepticus (NORSE) is a rare but severe clinical syndrome. Despite rigorous evaluation, the underlying cause is unknown in 30%–50% of patients and treatment strategies are largely empirical. The aim of this study was to describe clinical outcomes in a cohort of well‐phenotyped, thoroughly investigated patients who survived the initial phase of cryptogenic NORSE managed in specialist centers. Methods: Well‐characterized cases of cryptogenic NORSE were identified through the EPIGEN and Critical Care EEG Monitoring Research Consortia (CCEMRC) during the period 2005–2019. Treating epileptologists reported on post‐NORSE survival rates and sequelae in patients after discharge from hospital. Among survivors >6 months post‐discharge, we report the rates and severity of active epilepsy, global disability, vocational, and global cognitive and mental health outcomes. We attempt to identify determinants of outcome. Results: Among 48 patients who survived the acute phase of NORSE to the point of discharge from hospital, 9 had died at last follow‐up, of whom 7 died within 6 months of discharge from the tertiary care center. The remaining 39 patients had high rates of active epilepsy as well as vocational, cognitive, and psychiatric comorbidities. The epilepsy was usually multifocal and typically drug resistant. Only a minority of patients had a good functional outcome. Therapeutic interventions were heterogenous during the acute phase of the illness. There was no clear relationship between the nature of treatment and clinical outcomes. Significance: Among survivors of cryptogenic NORSE, longer‐term outcomes in most patients were life altering and often catastrophic. Treatment remains empirical and variable. There is a pressing need to understand the etiology of cryptogenic NORSE and to develop tailored treatment strategies. [ABSTRACT FROM AUTHOR]

Atherosclerosis remains a leading cause of cardiovascular disease (CVD) globally, with the complex interplay of inflammation and lipid metabolism at its core. Recent evidence suggests a role of B cells in the pathogenesis of atherosclerosis; however, this relationship remains poorly understood, particularly in the context of HIV. We review the multifaceted functions of B cells in atherosclerosis, with a specific focus on HIV. Unique to atherosclerosis is the pivotal role of natural antibodies, particularly those targeting oxidized epitopes abundant in modified lipoproteins and cellular debris. B cells can exert control over cellular immune responses within atherosclerotic arteries through antigen presentation, chemokine production, cytokine production, and cell–cell interactions, actively participating in local and systemic immune responses. We explore how HIV, characterized by chronic immune activation and dysregulation, influences B cells in the context of atherosclerosis, potentially exacerbating CVD risk in persons with HIV. By examining the proatherogenic and antiatherogenic properties of B cells, we aim to deepen our understanding of how B cells influence atherosclerotic plaque development, especially within the framework of HIV. This research provides a foundation for novel B cell‐targeted interventions, with the potential to mitigate inflammation‐driven cardiovascular events, offering new perspectives on CVD risk management in PLWH.

Indigenous nurse scholars across nations colonised by Europeans articulate the need for accomplices (as opposed to mere performative allies) to work alongside them and support their ongoing struggle for health equity and respect and to prioritise and promote culturally safe healthcare. Although cultural safety is now being mandated in nursing codes of practice as a strategy to address racism in healthcare, it is important that white nurse educators have a comprehensive understanding about cultural safety and the pedagogical skills needed to teach it to undergraduate nurses. We open this article with stories of our journeys as two white nurses in becoming accomplices and working alongside Indigenous Peoples, as patients and colleagues. Our lived experience of the inertia of healthcare and education organisations to address systemic and institutional resistance to the practice of cultural safety underpins the intention of this article. We understand that delivering this challenging and complex topic effectively and respectfully is best achieved when Indigenous and white educators work together at the cultural interface. Doing so requires commitment from white nurses and power holders within universities and healthcare institutions. A decolonising approach to nurse education at individual and institutional levels is fundamental to support and grow the work that needs to be done to reduce health inequity and increase cultural safety. White nurse accomplices can play an important role in teaching future nurses the importance of critical reflection and aiming to reduce power imbalances and racism within healthcare environments. Reducing power imbalances in healthcare environments and decolonising nursing practice is the strength of a cultural safety framework. [ABSTRACT FROM AUTHOR]

The axoneme, a microtubule‐based array at the center of every cilium, has been the subject of structural investigations for decades, but only recent advances in cryo‐EM and cryo‐ET have allowed a molecular‐level interpretation of the entire complex to be achieved. The unique properties of the nine doublet microtubules and central pair of singlet microtubules that form the axoneme, including the highly decorated tubulin lattice and the docking of massive axonemal complexes, provide opportunities and challenges for sample preparation, 3D reconstruction and atomic modeling. Here, the approaches used for cryo‐EM and cryo‐ET of axonemes are reviewed, while highlighting the unique opportunities provided by the latest generation of AI‐guided tools that are transforming structural biology.

Background: People with severe mental illness (SMI), such as schizophrenia, have higher rates of type 2 diabetes and worse outcomes, compared to those without SMI and it is not known whether diabetes self‐management interventions are effective for people who have both conditions. Research in this area has been impeded by a lack of consensus on which outcomes to prioritise in people with co‐existing SMI and diabetes. Aims: To develop a core outcome set (COS) for use in effectiveness trials of diabetes self‐management interventions in adults with both type 2 diabetes and SMI. Methods: The COS was developed in three stages: (i) identification of outcomes from systematic literature review of intervention studies, followed by multi‐stakeholder and service user workshops; (ii) rating of outcomes in a two‐round online Delphi survey; (iii) agreement of final 'core' outcomes through a stakeholder consensus workshop. Results: Seven outcomes were selected: glucose control, blood pressure, body composition (body weight, BMI, body fat), health‐related quality of life, diabetes self‐management, diabetes‐related distress and medication adherence. Conclusions: This COS is recommended for future trials of effectiveness of diabetes self‐management interventions for people with SMI and type 2 diabetes. Its use will ensure trials capture important outcomes and reduce heterogeneity so findings can be readily synthesised to inform practice and policy. [ABSTRACT FROM AUTHOR]

This article discusses the scholarly interest in Minority-Serving Institutions (MSIs) and the need for research on community colleges that are also MSIs. It highlights the importance of studying these institutions in order to understand how they address historical inequities and support students from racially and ethnically minoritized backgrounds. The article is organized into three themes: contexts and outcomes, curricular experiences, and leadership and administration. It includes research on topics such as race-conscious institutional practices, online education at Tribal Colleges, and the impact of HSI Title III grant monies on STEM degrees. The article acknowledges the limited representation of all MSI types but hopes to inform future conversations and research on Minority-Serving community colleges. [Extracted from the article]

Traditionally, ecosystem restoration has focussed on standard ecological indicators like water or habitat quality, species population abundance or vegetation cover to determine success. However, there is growing interest in how restoration might impact people and communities. For example, researchers have documented positive socio‐ecological links between restoration and human well‐being indicators like property value, natural hazard mitigation, recreation opportunity and happiness. Furthermore, public health benefits from restoration have been linked to public support for programmes.Drawing from this research, the United Nations declared 2021–2030 the 'Decade of Ecosystem Restoration' and set a goal to promote more socio‐ecological goals in ecosystem restoration. Nonetheless, there is still a lack of information on the extent to which restoration practitioners consider well‐being because many granting programmes only require ecological goals and monitoring.To explore how restoration practitioners design, implement and measure the success of their projects, we used the federally funded Great Lakes Restoration Initiative (GLRI) as a case study. Since 2010, GLRI has awarded over $3.5 Billion to over 5300 projects across the midwestern United States, but it does not presently require human well‐being considerations. We performed an online survey targeting project managers with a sample of GLRI projects (N = 1574). We received 437 responses and found that almost half set a human well‐being goal, and more than 70% of those who did believe they reached it. In comparison, 90% of project managers believed they met their ecological goals.These documented perceptions of positive impacts for both people and nature suggest that restoration may already transcend traditional indicators and monitoring for socio‐ecological metrics could capture many 'unseen' benefits. Therefore, we recommend that ecosystem restoration programmes adopt a socio‐ecological lens to document the full extent of their restoration outcomes.

INTRODUCTION: Virtually all people with Down syndrome (DS) develop neuropathology associated with Alzheimer's disease (AD). Atrophy of the hippocampus and entorhinal cortex (EC), as well as elevated plasma concentrations of neurofilament light chain (NfL) protein, are markers of neurodegeneration associated with late‐onset AD. We hypothesized that hippocampus and EC gray matter loss and increased plasma NfL concentrations are associated with memory in adults with DS. METHODS: T1‐weighted structural magnetic resonance imaging (MRI) data were collected from 101 participants with DS. Hippocampus and EC volume, as well as EC subregional cortical thickness, were derived. In a subset of participants, plasma NfL concentrations and modified Cued Recall Test scores were obtained. Partial correlation and mediation were used to test relationships between medial temporal lobe (MTL) atrophy, plasma NfL, and episodic memory. RESULTS: Hippocampus volume, left anterolateral EC (alEC) thickness, and plasma NfL were correlated with each other and were associated with memory. Plasma NfL mediated the relationship between left alEC thickness and memory as well as hippocampus volume and memory. DISCUSSION: The relationship between MTL gray matter and memory is mediated by plasma NfL levels, suggesting a link between neurodegenerative processes underlying axonal injury and frank gray matter loss in key structures supporting episodic memory in people with DS.

Parallel transmit MRI at 7 T has increasingly been adopted in research projects and provides increased signal‐to‐noise ratios and novel contrasts. However, the interactions of fields in the body need to be carefully considered to ensure safe scanning. Recent advances in physically flexible body coils have allowed for high‐field abdominal imaging, but the effects of increased variability on energy deposition need further exploration. The aim of this study was to assess the impact of subject geometry, respiration phase and coil positioning on the specific absorption rate (SAR). Ten healthy subjects (body mass index [BMI] = 25 ± 5 kg m−2) were scanned (at 3 T) during exhale breath‐hold and images used to generate body models. Seven of these subjects were also scanned during inhale. Simplifications of the coil and body models were first explored, and then finite‐difference time‐domain simulations were run with a typical eight‐channel parallel transmit coil positioned over the abdomen. Simulations were used to generate 10 g averaged SAR (SAR10g) maps across 100,000 phase settings, and the worst‐case scenario 10 g averaged SAR (wocSAR10g) was identified using trigonometric maximisation. The average maximum SAR10g across the 10 subjects with 1 W input power per channel was 1.77 W kg−1. Hotspots were always close to the body surface near the muscle wall boundary. The wocSAR10g across the 10 subjects ranged from 2.3 to 3.2 W kg−1 and was inversely correlated to fat volume percentage (R = 8) and BMI (R = 0.6). The coefficient of variation values in SAR10g due to variations in subject geometry, respiration phase and realistic coil repositioning were 12%, 4% and 12%, respectively. This study found that the variability due to realistic coil repositioning was similar to the variability due to differing healthy subject geometries for abdominal imaging. This is important as it suggests that population‐based modelling is likely to be more useful than individual modelling in setting safe thresholds for abdominal imaging. [ABSTRACT FROM AUTHOR]

Loneliness is a perceived deficit in social relationships that is nested within broader cultural meaning systems. This longitudinal study examined predictors of loneliness in Chinese and U.S. children with the hypothesis that peer relationship parameters (number of friends, social preference, and popularity) mediate the associations between behavior qualities and loneliness differently across countries. Fifth‐grade Chinese (n = 576, Mage = 10.58 years) and U.S. (White, Black, Asian, n = 540; Mage = 10.23 years) children completed two waves of assessment within an academic year. Shyness and athletic competence more strongly predicted loneliness for U.S. children, and academic ability, and aggression more strongly predicted loneliness for Chinese children. Popularity was a mediator for U.S. children but not Chinese children. [ABSTRACT FROM AUTHOR]

Glasdegib (DAURISMO) is a hedgehog pathway inhibitor approved for the treatment of acute myeloid leukemia (AML). Cytochrome P450 3A4 (CYP3A4) has been identified as a major metabolism and clearance pathway for glasdegib. The role of CYP3A4 in the clearance of glasdegib has been confirmed with clinical drug–drug interaction (DDI) studies following the coadministration of glasdegib with the strong CYP3A4 inhibitor ketoconazole and the strong inducer rifampin. To evaluate potential drug interactions with CYP3A4 modulators, the coadministration of glasdegib with a moderate CYP3A4 inducer, efavirenz, was evaluated using physiologically based pharmacokinetic (PBPK) modeling using the Simcyp simulator. The glasdegib compound file was developed using measured physicochemical properties, data from human intravenous and oral pharmacokinetics, absorption, distribution, metabolism, and excretion studies, and in vitro reaction phenotyping results. The modeling assumptions, model parameters, and assignments of fractional CYP3A4 metabolism were verified using results from clinical pharmacokinetics (PK) and DDI studies with ketoconazole and rifampin. The verified glasdegib and efavirenz compound files, the latter of which was available in the Simcyp simulator, were used to estimate the potential impact of efavirenz on the PK of glasdegib. PBPK modeling predicted a glasdegib area under the concentration–time curve ratio of 0.45 and maximum plasma concentration ratio of 0.75 following coadministration with efavirenz. The PBPK results, in lieu of a formal clinical study, informed the drug label, with the recommendation to double the clinical dose of glasdegib when administered in conjunction with a moderate CYP3A4 inducer, followed by a resumption of the original dose 7 days post‐discontinuation.

Background: Nursing assistants working in long‐term care (LTC) often report that their job is stressful. To reduce their work stress, a better understanding of their stress profile is needed. Objective: We aimed to pilot test methods to identify and understand stressors that LTC nursing assistants experience. Methods: We asked each participant to provide wearable sensor/watch data, ecological momentary assessment (EMA) surveys and end of day review data over two eight‐hour working shifts. Results: Eight nursing assistants participated. All participants worked in a common continuing care retirement community in Maryland, United States of America. Our stress assessment method revealed 83 stressful events that were classified under 10 categories. Most of the reported events were rated as having a mild to low‐moderate intensity. The three most common causes of stress were work demands and pressure (28.35%), heavy workload and staffing (19.69%), and safety issues and COVID‐19 concerns (17.32%). We also explored the difference between stress events and intensity among different shifts. Disrespect from residents (22.73%) was the most commonly reported stressor during day shifts. Feeling rushed was the most commonly reported stressor during the evening (22.47%) and the night (38.46%) shifts. Conclusions: We found stress was commonly reported. Stress intensity conflicted with prior literature, and we explored possible explanations. Implications for practice: We discuss potential implications for these findings, modification of our methods to increase feasibility, the utility of these data collection methods for future work and suggest next steps.

Background: A work‐focused fatigue management intervention, Fatigue and Activity Management Education for Work (FAME‐W) programme was developed for individuals with inflammatory arthritis (IA) to manage fatigue in order to maintain demands of their work activities and tasks. This paper presents the protocol for a randomized control trial that will test the effectiveness and acceptability of FAME‐W in improving work performance. Methods: This protocol presents a multisite randomized control trial and mixed methods process evaluation. Eligible participants will be aged 18–65 years with a diagnosis of inflammatory arthritis and will be in paid employment. The primary outcome of the study will be Work Role Functioning (WRF) questionnaire, and the secondary outcomes will be fatigue, mood, health‐related quality of life (HRQOL) and pain. Data will be collected immediately pre‐ and post‐intervention and at 3 months of follow‐up. The process evaluation will consist of focus groups and individual interviews to explore participants' experiences of FAME‐W. Occupational therapists delivering the programme will complete a facilitator log to assess the fidelity and quality of intervention implementations. Facilitators will participate in individual interviews to explore intervention delivery and acceptability. Results: Results will be expected to show that FAME‐W will improve work performance by helping participants gain self‐management strategies around managing fatigue and other symptoms related to fatigue. Conclusion: It is hoped that FAME‐W will be an effective and acceptable intervention for individuals with IA in improving work performance by helping them manage their symptoms.

Background: Healthcare workers (HCWs) have suffered considerable morbidity and mortality during the COVID‐19 pandemic. Few studies have evaluated the CoronaVac vaccine effectiveness (VE), particularly in Eastern Europe, where the vaccine has been widely used. Methods: We conducted a prospective cohort study among HCWs in seven hospitals in Baku, Azerbaijan between May 17 and November 30, 2021, to evaluate primary series (two‐dose) CoronaVac VE against symptomatic SARS‐CoV‐2 infection. Participants completed weekly symptom questionnaires, provided nasopharyngeal swabs for SARS‐CoV‐2 RT‐PCR testing when symptomatic, and provided serology samples at enrollment that were tested for anti‐spike and anti‐nucleocapsid antibodies. We estimated VE as (1 – hazard ratio)*100 using a Cox proportional hazards model with vaccination status as a time‐varying exposure, adjusting for hospital and previous SARS‐CoV‐2 infection status. Results: We enrolled 1582 HCWs. At enrollment, 1040 (66%) had received two doses of CoronaVac; 421 (27%) were unvaccinated. During the study period, 72 PCR‐positive SARS‐CoV‐2 infections occurred; 36/39 (92%) sequenced samples were classified as Delta variants. Primary series VE against COVID‐19 illness was 29% (95% CI: −51%; 67%) for the entire analysis period. For the Delta‐only period (July 1–November 30, 2021), primary series VE was 19% (95% CI: −81%; 64%). For the entire analysis period, primary series VE was 39% (95% CI: −40%; 73%) for HCWs vaccinated within 14–149 days and 19% (95% CI: −81%; 63%) for those vaccinated ≥150 days. Conclusions: During a period in Azerbaijan characterized by mostly Delta circulation, VE point estimates suggested that primary series CoronaVac protected nearly 1 in 3 HCWs against COVID‐19, but 95% confidence intervals were wide, with lower bounds that crossed zero, reflecting the limited precision of our VE estimates. Our findings underscore the need to consider booster doses for individuals who have received the primary series of CoronaVac. [ABSTRACT FROM AUTHOR]

Objectives: To test the hypotheses that: (1) Prevalence of periodontal disease would be higher in people with a history of psychosis when compared to the general population and (2) Demographic, life‐style related factors and co‐morbid medical conditions would predict periodontal disease in people experiencing psychosis. Methods: The authors performed cross‐sectional analysis of baseline data from the UK Biobank study (2007–2010), identifying cases with psychosis using clinical diagnosis, antipsychotic medication, and self‐report. Demographic (age, gender, ethnicity, socioeconomic status), lifestyle‐related(BMI, blood pressure, smoking and alcohol intake, physical activity) and physical co‐morbidities (cancer, cardiovascular, respiratory, inflammatory disease and metabolic conditions) were included as potential risk factors for periodontal disease among people with a history of psychosis using logistic regression analyses. The analysis sample included 502,505 participants. Results: Risk of periodontal disease was higher in people with psychosis, regardless of how cases were identified. Patients with a clinical diagnosis had the highest proportion of periodontal disease compared to the general population (21.3% vs. 14.8%, prevalence ratio 1.40, 95% CI: 1.26–1.56). Older and female cases were more likely to experience periodontal disease. Lifestyle factors (smoking) and comorbidities (cardiovascular, cancer or respiratory disease) were associated with periodontal disease among people with a history of psychosis. Conclusions: The findings suggest that periodontal disease is more common in people with a history of psychosis, compared to the general population. Prevention and early diagnosis of periodontal disease should be a priority for oral health promotion programmes, which should also address modifiable risk factors like smoking which also contribute to co‐morbid systemic disease.

Introduction: Fatigue and Activity Management Education for Work (FAME‐W) is a four‐week, occupational therapy led programme focussing on fatigue management strategies. FAME‐W was designed to be delivered in person; however, due to COVID‐19 pandemic it was modified to be an online group‐based self‐management intervention. The purpose of this study was to test the feasibility and acceptability of the online delivery format of FAME‐W. Methods: This was a mixed methods study. Participants were randomly allocated to intervention or control group. Participants in the intervention group received a four‐week online FAME‐W. The control group participants received a FAME‐W handbook. Participants were required to complete questionnaires on work presenteeism, fatigue, mood, Health Related Quality of Life and pain at baseline, and 3 months post‐intervention. Participants in the intervention group attended a focus group immediately following the completion of the programme and the control group participated in individual interviews. Results: Seven of ten individuals recruited participated in the study. Majority of participants had Rheumatoid Arthritis and were working full‐time. The mean age of intervention participants was 53 ± 10.4 and 56.5 ± 3.7 for the controls. All participants in the intervention group had 100% attendance, completed all study measures and activities. Participants had positive comments about the programme format, content, and delivery. Improvements were observed in most measures at follow up. Conclusion: Results suggest that an online programme to improve work ability was feasible and acceptable to individuals with inflammatory arthritis. The online delivery format was favoured over attending a centre‐based programme. The findings support a definitive intervention trial of online FAME‐W. [ABSTRACT FROM AUTHOR]

Background and aims: Alcohol's harm to others (AHTO) has become a key driver of national and international alcohol policy. This study aimed to produce a contemporary, comprehensive estimate of the correlates and harms from others' drinking in 2021 in Australia. Design, setting, participants and measurements: Across Australia, 2574 adults (1380 women; 1172 men) were sampled via two cross‐sectional survey modes: a random‐digit dial mobile phone sample of 1000 people and 1574 people from the Life in Australia™ panel survey. In 2021 participants were asked about harms they had experienced from the drinking of family, friends, co‐workers and the public in the past year. Applying combined sample weights from each mode, bivariable and adjusted multivariable logistic regressions were used to analyse differences in rates of AHTO by participant gender, age, residence in rural or metropolitan regions, country of birth, education and employment. Findings: In 2021, 23.6% reported being negatively affected by strangers' drinking and 21.3% by the drinking of someone they knew, with 34.3% reporting being negatively affected a lot or a little by either; 42.4% of respondents reported specific harms from strangers' drinking. Thus, 48.1% of respondents reported any harm (negative effects or specific harms) from others' drinking. Women, younger people, Australian‐born and heavier episodic drinkers reported significantly higher rates of AHTO compared with other respondents. Smaller percentages (7.5%) of participants reported being harmed substantially by others' drinking, including by people they knew (5.8%) or strangers (2.3%). Stratified analyses showed that heavier drinking, furloughed, younger men who were born overseas in English‐speaking countries were affected by others' drinking, whereas women were affected regardless of these factors (apart from age). Conclusions: More than one‐third of Australian adults appear to have been negatively affected by others' drinking in 2021, with women, younger people and heavier drinkers at greater risk. Substantial harm appears to be more likely to arise from the drinking of people Australians know than from strangers' drinking. [ABSTRACT FROM AUTHOR]

Aim: The therapeutic alliance is a robust predictor of treatment outcome. However, little is known about the way alliance negotiation contributes to psychotherapy outcome. The aim of the present study was to analyze the effects of alliance negotiation on treatment outcome in the first four sessions of psychotherapy. Methods: Ninety‐six patients diagnosed with emotional disorders received weekly Solution‐Focused Brief Therapy. Each patient completed both the Alliance Negotiation Scale (ANS) and the Outcome Questionnaire 45 (OQ.45) after each of the first four sessions. Both between‐ and within‐patients effects of alliance negotiation on symptom severity were analyzed using Hierarchical Linear Models. Results: Results showed significant between and within patient effects of alliance negotiation on symptom severity. Patients with higher levels of alliance negotiation across treatment showed lower levels of symptom severity (between‐patient effect). Also, in a session with higher alliance negotiation compared to the average session of this patient, symptom severity was lower than in the average session (within‐patient effect). Discussion: The results indicate that therapies characterized by higher alliance negotiation and sessions with higher alliance negotiation are beneficial for early outcome. Conclusion: From a clinical point of view, the results suggest that alliance negotiation is a meaningful factor for therapy outcome and that therapists may benefit from training and monitoring alliance negotiation during the early stages of treatment.

Type VIIb secretion systems (T7SSb) in Gram‐positive bacteria facilitate physiology, interbacterial competition, and/or virulence via EssC ATPase‐driven secretion of small ɑ‐helical proteins and toxins. Recently, we characterized T7SSb in group B Streptococcus (GBS), a leading cause of infection in newborns and immunocompromised adults. GBS T7SS comprises four subtypes based on variation in the C‐terminus of EssC and the repertoire of downstream effectors; however, the intraspecies diversity of GBS T7SS and impact on GBS‐host interactions remains unknown. Bioinformatic analysis indicates that GBS T7SS loci encode subtype‐specific putative effectors, which have low interspecies and inter‐subtype homology but contain similar domains/motifs and therefore may serve similar functions. We further identify orphaned GBS WXG100 proteins. Functionally, we show that GBS T7SS subtype I and III strains secrete EsxA in vitro and that in subtype I strain CJB111, esxA1 appears to be differentially transcribed from the T7SS operon. Furthermore, we observe subtype‐specific effects of GBS T7SS on host colonization, as CJB111 subtype I but not CNCTC 10/84 subtype III T7SS promotes GBS vaginal colonization. Finally, we observe that T7SS subtypes I and II are the predominant subtypes in clinical GBS isolates. This study highlights the potential impact of T7SS heterogeneity on host‐GBS interactions.

Aim: Lungfishes are one of the two surviving clades from the once diverse grade of lobe‐finned fishes leading to tetrapods. This classic living fossil lineage, which is the living sister to four‐limbed terrestrial vertebrates, appeared approximately 425 million years ago and rapidly diversified. However, the evolution of lungfishes after their initial radiation is poorly understood, and whether their present distribution tracks ancient geographical change is a classic problem in biogeography. Location: Global. Taxon: Lungfishes (Dipnoi). Methods: Here, we combine mitogenomic, nuclear gene and fossil data to reconstruct the timing of lungfish diversification a Bayesian tip‐dating approach to quantitatively test hypotheses of lungfish historical biogeography and divergence times. We sample all major living and extinct lungfish lineages, including three of the four species of African lungfishes (Protopterus spp.), the Australian lungfish Neoceratodus forsteri, the South American lungfish Lepidosiren paradoxa and 13 fossils representing extinct lineages from across the globe. Results: Our results demonstrate that the divergences of the three major living lungfish clades closely recapitulate the stepwise fragmentation of the Gondwana during the Mesozoic. All of our model‐based biogeographical reconstructions support a Gondwanan vicariance model for the origins of the present distribution of lungfish lineages. Conclusions: In turn, lungfishes provide an excellent example of how the integration of fossil data may drastically change support for historical biogeographical hypotheses previously discounted by molecular data and are one of the few living animal lineages that record incredibly ancient geographical changes in their phylogeny.

Background: Complex peripatellar defects are commonly reconstructed with free flaps or pedicled muscle flaps, whereas pedicled fasciocutaneous perforator flaps are commonly overlooked. The descending genicular artery perforator (DGAP) flap is a versatile flap that offers thin and pliable tissue that provides ideal 'like with like' peripatellar soft tissue defect reconstruction. This paper aims to demonstrate the safe use of a pedicled fasciocutaneous DGAP flap for extensive traumatic peripatellar defect reconstructions and to exhibit the surgical pearls via a case series. Methods: A retrospective cohort study of consecutive complex peripatellar reconstructions with DGAP flaps was conducted from January 2011 to December 2018. Patient demographics, medical comorbidities, aetiology/size/and location of the defects were reviewed. Flap, donor site, and overall surgical outcomes were clinically assessed and documented. Descriptive statistics were conducted and analysed by IBM SPSS Statistics 23. Results: Five consecutive cases with complex peripatellar defects (5 × 8 to 8 × 10 cm) were recruited. Two were males, and three were females, with a mean age of 38.4 years. Four were trauma, and one was an oncological case. Descending genicular artery (DGA) perforators and DGA terminal branches were consistent. One patient needed a split‐thickness skin graft to reconstruct the secondary defects. All the flaps survived with an average follow‐up of 24 months. Conclusion: The DGAP flap provides a reliable alternative to free flap for the large, complex peripatellar defect. With the inclusion of the proximal long saphenous vein and judicious selection of DGA perforators and its terminal branches, the DGAP flap can be harvested and used safely in the high‐velocity impacted knee.

Resistance to platinum‐based chemotherapy is the major cause of death from high‐grade serous ovarian cancer (HGSOC). We hypothesise that detection of specific DNA methylation changes may predict platinum resistance in HGSOC. Using a publicly available "discovery" dataset we examined epigenomic and transcriptomic alterations between primary platinum‐sensitive (n = 32) and recurrent acquired drug resistant HGSOC (n = 28) and identified several genes involved in immune and chemoresistance‐related pathways. Validation via high‐resolution melt analysis of these findings, in cell lines and HGSOC tumours, demonstrated the most consistent changes were observed in three of the genes: APOBEC3A, NKAPL and PDCD1. Plasma samples from an independent HGSOC cohort (n = 17) were analysed using droplet digital PCR. Hypermethylation of NKAPL was detected in 46% and hypomethylation of APOBEC3A in 69% of plasma samples taken from women with relapsed HGSOC (n = 13), with no alterations identified in disease‐free patients (n = 4). Following these results, and using a CRISPR‐Cas9 approach, we were also able to demonstrate that in vitro NKAPL promoter demethylation increased platinum sensitivity by 15%. Overall, this study demonstrates the importance of aberrant methylation, especially of the NKAPL gene, in acquired platinum resistance in HGSOC. [ABSTRACT FROM AUTHOR]

Objectives: Long‐term home range stability presumably emerges because familiarity with an area improves fitness through increased foraging efficiency, reduced predation risk, or reduced costs of intergroup aggression. While the use of spatial memory by primates has been widely demonstrated, few studies have examined whether long‐term space use creates opportunities for interannual reuse of spatial knowledge. Here we examine the ranging behavior of western gorillas (Gorilla gorilla) to assess the degree of long‐term site fidelity and the foraging consequences of reuse of space. Methods: We measured interannual home range overlap over a 10‐year period for a single group of gorillas at the Mondika Research Center, using both grid‐based and kernel density estimation. By plotting the total area used over time, we identified periods of home‐range stability and expansion. We compared foraging and ranging behavior in familiar versus unfamiliar areas, considering fruit trees visited, dietary diversity, and daily path length, to determine whether the lack of spatial knowledge in unfamiliar areas was associated with foraging costs. Results: Average interannual home range overlap by the group remained high throughout the study. During periods of home range expansion, daily path lengths increased but not the number of fruit trees visited, suggesting that reduced familiarity with the area led to decreased foraging efficiency because individuals lacked prior knowledge of where to find resources. Discussion: Western gorillas at Mondika exhibit long‐term home range stability, presumably reflecting a strategy that relies on the use of spatial memory to increase foraging efficiency that is favored by their reliance on ephemeral fruit resources.

This two‐wave longitudinal study examined peer selection and influence pertaining to tobacco and alcohol use by adolescents and their friends in a sample of 854 Chinese adolescents (384 girls: mean age = 13.33 years). Participants nominated friends and self‐reported their tobacco and alcohol use at seventh and again at eighth grade. Longitudinal social network analyses revealed evidence of friend influence but not selection over smoking and drinking. Boys increased their levels of smoking at rates greater than that of girls, but no sex moderation of either selection or influence was found. In interpreting these results, it is important to understand the gender norms for Chinese boys and girls and the cultural context of tobacco and alcohol use. [ABSTRACT FROM AUTHOR]

Polycyclic aromatic hydrocarbons (PAHs) are persistent organic compounds of major concern that mainly accumulate in soils and sediments, and their extraction from environmental matrices remains a crucial step when determining the extent of contamination in soils and sediments. The objective of the present study was to compare the extraction of PAHs (phenanthrene, pyrene, chrysene, and benzo[a]pyrene) from spiked soil and sediment using supercritical fluid extraction (SFE) with ethanol as the modifier, microwave‐assisted extraction (MAE), and eucalyptus oil–assisted extraction (EuAE). Recoveries of PAHs were comparable between the three methods, and >80% of applied pyrene, chrysene and benzo[a]pyrene were recovered. The most efficient method of extracting PAHs from naturally incurred soils with different levels of contamination was SFE. A longer extraction time was required for the EuAE method compared with SFE and MAE under optimized conditions. However, EuAE required lower extraction temperatures (15–20 °C) compared with SFE (80 °C) and MAE (110–120 °C), and consumed less solvent than SFE and MAE. Compared with hexane/acetone used in MAE, the use of ethanol in SFE and eucalyptus oil in EuAE can be considered as more sustainable approaches to efficiently extract PAHs from spiked/naturally contaminated soils and sediments. And, although less efficient for matrices containing higher carbon content, EuAE offered a cheap, low‐tech approach to extracting PAHs. Environ Toxicol Chem 2023;42:982–994. © 2023 The Authors.

New Findings: What is the central question of the study?Can a novel, energy‐dense and lightweight ketogenic bar (1000 kcal) consumed 3 h before exercise modulate steady‐state incline rucksack march ('ruck') performance compared to isocaloric carbohydrate bars in recreationally active, college‐aged men?What is the main finding and its importance?Acute ingestion of either nutritional bar sustained ∼1 h of exhaustive rucking with a 30% of body weight rucksack. This proof‐of‐concept study is the first to demonstrate that carbohydrate bars and lipid bars are equally feasible for preserving ruck performance. Novel ketogenic nutrition bars may have military‐relevant applications to lessen carry load without compromising exercise capacity. Rucksack marches ('rucks') are strenuous, military‐relevant exercises that may benefit from pre‐event fuelling. The purpose of this investigation was to explore whether acute ingestion of carbohydrate‐ or lipid‐based nutritional bars before rucking can elicit unique advantages that augment exercise performance. Recreationally active and healthy males (n = 29) were randomized and counterbalanced to consume 1000 kcal derived from a novel, energy‐dense (percentage energy from carbohydrate/fat/protein: 5/83/12) ketogenic bar (KB), or isocaloric high‐carbohydrate bars (CB; 61/23/16) 3 h before a time‐to‐exhaustion (TTE) ruck. Conditions were separated by a 1‐week washout. The rucksack weight was standardized to 30% of bodyweight. Steady‐state treadmill pace was set at 3.2 km/h (0.89 m/s) and 14% grade. TTE was the primary outcome; respiratory exchange ratio (RER), capillary ketones (R‐β‐hydroxybutyrate), glucose and lactate, plus subjective thirst/hunger were the secondary outcomes. Mean TTE was similar between conditions (KB: 55 ± 25 vs. CB: 54 ± 22 min; P = 0.687). The RER and substrate oxidation rates revealed greater fat and carbohydrate oxidation after the KB and CB, respectively (all P < 0.0001). Capillary R‐βHB increased modestly after the KB ingestion (P < 0.0001). Neither bar influenced glycaemia. Lactate increased during the ruck independent of the condition (P < 0.0001). Thirst/fullness perceptions changed independent of the nutritional bar consumed. A novel KB nutritional bar produced equivalent TTE ruck results to the isocaloric CBs. The KB's energy density relative to CB (6.6 vs. 3.8 kcal/g) may provide a lightweight (–42% weight), pre‐event fuelling alternative that does not compromise ruck physical performance.

American black bears (Ursus americanus) in Florida have increased in abundance from historically low numbers and currently number >4,000 across 7 subpopulations. Biologists monitor the range of black bears to track their recovery for conservation and management efforts. We estimated geographic range of black bears in Florida for historical (2001–2010) and contemporary (2011–2020) periods using 12 sources of occurrence data collected from wildlife professionals and the public. We reduced data sets by subsampling protocols to account for localized spatiotemporal biases and for possible differences in sampling effort from increases in the human population between modeling periods. We developed models at 2 levels: a generalized boundary (range extent) and a more detailed delineation (occupied range). We developed range extent using a concave hull model and occupied range using kernel density estimation with a corresponding 97.5% isopleth. Between modeling periods, range extent increased by 13.4% and occupied range increased by 11.3%, with both range levels expanding and contracting in certain areas. The ranges indicated improved connectivity among bear subpopulations. We also produced a range map for research, management, and public use built upon contemporary data that partitioned the state into 4 levels representing the relative frequency of bear use (frequent, common, occasional, and rare). Range map levels at the occupied range, and especially frequent use areas, help focus bear research efforts (e.g., placement of hair corrals), management efforts (e.g., assess varying levels of risk to the public of bear conflicts), and conservation efforts (e.g., focusing habitat protection in areas with high use by bears).

Summary: Whey protein hydrolysates are important food emulsifiers and bioactive ingredients. This study investigated the stability of whey protein isolate (WPI) bioactive peptide fraction nanoemulsions under representative food processing and storage conditions: pH (3–9), ion concentration (Na+, 0–200 mm and Ca2+, 0–15 mm), thermal treatment (30–90 °C) and freeze–thawing. Bioactive peptide fractions, UC–10 and UP–10, were obtained by ultrafiltration of chymotrypsin or pepsin WPI hydrolysates, respectively. The nanoemulsions produced with these fractions had droplet diameters of 177 ± 3.5 nm (UC–10) and 154 ± 1.6 nm (UP–10). Nanoemulsions destabilised at pH 3–5, around the isoelectric point of WPI proteins but were stable at higher pH values, 6–9. Nanoemulsion instability escalated above critical Na+ (25 mm) and Ca2+ (2.5 mm) concentrations, but Ca2+ accelerated droplet aggregation more strongly than Na+. Furthermore, nanoemulsions were moderately stable to heating and freeze–thawing. Overall, both WPI bioactive peptide‐stabilised nanoemulsions showed consistent stability to the processing conditions. This study expands on designing, producing and utilising nanoemulsions based on WPI bioactive peptides. [ABSTRACT FROM AUTHOR]

Circular supply chains require more accurate product labeling and traceability. In the apparel industry, product life cycle management is hampered in part by inaccurate, poorly readable, and detachable standard care labels. Instead, this article seeks to enable a labeling system capable of being integrated into the fabric itself, intrinsically recyclable, low‐cost, encodes information, and allows rapid readout after years of normal use. In this work, all‐polymer photonic crystals are designed and then fabricated by thermal drawing with >100 layers having sub‐micrometer individual thickness and low refractive index contrast (Δn = 0.1). The fibers exhibit reflectance features in the 1–5.5 µm wavelength range, characterized using insitu Fourier transform infrared spectroscopy. Drawn photonic fibers are then woven into fabrics, characterized by near‐infrared spectroscopy and short‐wave infrared imaging, techniques commonly used in industrial facilities for sorting materials. The fibers' optical design also enables the use of overtone peaks to avoid overlap with parasitic molecular absorption, substantially improving the signal‐to‐noise ratio (and therefore ease and speed) of readout. The ability to produce kilometers of fiber that are compatible with existing textile manufacturing processes, coupled with low input material cost, make these a potential market‐viable improvement over the standard care label.

The religious similarity of adolescents and their friends can arise from selection or influence. Prior studies were limited because of confounds that arose from the ethnic and religious heterogeneity of the samples and the use of cross‐sectional designs. SIENA was used in this two‐year longitudinal study of 825 Indonesian Muslim high school students (445 girls; mean age = 16.5 years) to assess peer selection and influence as these pertained to religiosity and religious coping. The analyses yielded significant influence but not selection effects for both religiosity and religious coping. This study is an important methodological advance over prior research and although limited by correlational data, nevertheless, provides evidence that adolescents influence their peers' religiousness.

Summary: This paper investigates the dynamic shear amplification in reinforced concrete shear walls designed according to the seismic provisions of the current Turkish Building Earthquake Code (TBEC‐2018). Shear walls with a high ductility level and different aspect ratios are examined to evaluate the design shear force calculated by using the dynamic amplification factor (βv) and overstrength factor (D) defined in TBEC‐2018. For this purpose, response spectrum analyses (RSAs) are first carried out on two‐dimensional cantilever shear walls with heights of 30, 45, and 60 m and with lengths of 1.5, 3, and 4.5 m in the plan. Then, a total of 198 nonlinear time history analyses (NLTHAs) are performed with real and simulated ground motions matched to the elastic design spectrum defined in TBEC‐2018. The comparison of the design shear forces obtained from RSA and the shear demands obtained from NLTHA along the heights of the walls reveals that the design shear forces calculated according to TBEC‐2018 may underestimate the actual shear demands from studied ground motions. Moreover, the applicability of the updates proposed to TBEC‐2018 for the design shear force and shear force diagram along the wall height in reinforced concrete shear wall‐frame systems to cantilever shear walls is also examined.

Introduction: There have been no published studies reporting health utilities among Aboriginal people attending residential rehabilitation for substance use treatment. This study aims to examine health utilities for Aboriginal people in residential rehabilitation and investigate the association between health utilities and length of stay. Methods: EuroQol‐5 Dimension 5‐level (EQ‐5D‐5L) raw data collected from three residential rehabilitation services in New South Wales, Australia was transferred into a quality‐adjusted health index using EQ‐5D‐5L Crosswalk Index Value Calculator. Clients were categorised into two groups based on their length of stay in treatment: ≤60 days or more than 60 days. Among people who stay longer than 60 days, we also examined health utilities by exit status (yes/no). Bootstrapping was used to examine the difference in improvement in health utilities from baseline to the latest assessment in both groups. Results: Our study included 91 clients (mean age 32 years old SD: 9). Mean health utility at baseline was 0.76 (SD 0.25) and at the latest assessment was 0.88 (SD 0.16). For clients staying 60 days, the incremental health utility was 0.13 (95% confidence interval [CI] 0.06–0.20; p < 0.01). For clients staying less than or equal to 60 days, the incremental health utility was 0.12 (95% CI 0.00–0.24; p = 0.06). For the total sample, the incremental health utility was 0.12 (95% CI 0.06–0.19; p < 0.01). Discussion and Conclusions: There is a significant improvement in health utilities for people staying longer in residential rehabilitation. Strategies to improve treatment retention could potentially increase quality of life for Aboriginal people in residential rehabilitation. [ABSTRACT FROM AUTHOR]

- Abstract
A largely unexplored part of the financial incentive for physicians to participate in preventive care is the degree to which they are the residual claimant from any resulting cost savings. We examine the impact of two preventive activities for people with serious mental illness (care plans and annual reviews of physical health) by English primary care practices on costs in these practices and in secondary care. Using panel two‐part models to analyze patient‐level data linked across primary and secondary care, we find that these preventive activities in the previous year are associated with cost reductions in the current quarter both in primary and secondary care. We estimate that there are large beneficial externalities for which the primary care physician is not the residual claimant: the cost savings in secondary care are 4.7 times larger than the cost savings in primary care. These activities are incentivized in the English National Health Service but the total financial incentives for primary care physicians to participate were considerably smaller than the total cost savings produced. This suggests that changes to the design of incentives to increase the marginal reward for conducting these preventive activities among patients with serious mental illness could have further increased welfare.

Airborne electromagnetic surveys collected in December 2011 and November 2018 and three soil sampling transects were used to analyze the spatial heterogeneity of shallow (<4 m) soil properties in lower Taylor Valley (TV), East Antarctica. Soil resistivities from 2011 to 2018 ranged from ∼33 Ωm to ∼3,500 Ωm with 200 Ωm assigned as an upper boundary for brine‐saturated sediments. Elevations below ∼50 m above sea level (masl) typically exhibit the lowest resistivities with resistivity increasing at high elevations on steeper slopes. Soil water content was empirically estimated from electrical resistivities using Archie's Law and range from ∼<1% to ∼68% by volume. An increase in silt‐ and clay‐sized particles at low elevations increases soil porosity but decreases hydraulic conductivity, promoting greater residence times of soil water at low elevations near Lake Fryxell. Soil resistivity variability between 2011 and 2018 shows soils at different stages of soil freeze‐thaw cycles, which are caused predominantly by solar warming of soils as opposed to air temperature. This study furthers the understanding of the hydrogeologic structure of the shallow subsurface in TV and identifies locations of soils that are potentially prone to greater rates of thaw and resulting ecosystem homogenization of soil properties from projected increases in hydrological connectivity across the region over the coming decades. Plain Language Summary: Liquid water is vital to all life on Earth; however, it is only available to life on land in Taylor Valley (TV), East Antarctica, during the brief Antarctic summer due to extremely cold and dry climate conditions. Water is released November‐February each year, providing nutrients to microbial and algal communities in the region. We used specialized instruments to locate liquid water in the subsurface and map soil water distributions to describe soil properties within TV in December 2011 and November 2018. Soil samples were collected to analyze how soil properties varied at different elevations and to determine how this variance affected soil water levels at different locations. Weather data were examined to study how climate variables affect soil water levels, and satellite imagery was used to examine snow conditions on the surface. We find that 2011 soils were typically wetter than 2018 soils, likely due to warmer climate conditions in 2011. Additionally, we found that low elevation soils were typically composed of finer‐grained sediments, which keep soil water in place for longer time periods. This research identifies areas more prone to thawing within the TV, which is important for understanding how soil organisms will be affected in a warming world. Key Points: McMurdo Dry Valleys soil properties are characterized using resistivity data from two airborne electromagnetic surveys from 2011 to 2018Soil water content in the shallow subsurface largely controls resistivity variabilityHigher percentages of silt‐ and clay‐sized particles at low elevations promote greater residence times of soil water [ABSTRACT FROM AUTHOR]

PF‐05212377 (SAM760) is a potent and selective 5‐HT6 antagonist, previously under development for the treatment of Alzheimer's disease. In vitro, PF‐05212377 was determined to be a P‐gp/non‐BCRP human transporter substrate. Species differences were observed in the in vivo brain penetration of PF‐05212377 with a ratio of the unbound concentration in brain/unbound concentration in plasma (Cbu/Cpu) of 0.05 in rat and 0.64 in non‐human primates (NHP). Based on pre‐clinical evidence, brain penetration and target engagement of PF‐05212377 was confirmed in NHP using positron emission tomography (PET) measured 5‐HT6 receptor occupancy (%RO). The NHP Cpu EC50 of PF‐05212377 was 0.31 nM (consistent with the in vitro human 5HT6 Ki: 0.32 nM). P‐gp has been reported to be expressed in higher abundance at the rat BBB and in similar abundance at the BBB of non‐human primates and human; brain penetration of PF‐05212377 in humans was postulated to be similar to that in non‐human primates. In humans, PF‐05212377 demonstrated dose and concentration dependent increases in 5‐HT6 RO; maximal 5‐HT6 RO of ∼80% was measured in humans at doses of ≥15 mg with an estimated unbound plasma EC50 of 0.37 nM (which was similar to the in vitro human 5HT6 binding Ki 0.32 nM). In conclusion, cumulative evidence from NHP and human PET RO assessments confirmed that NHP is more appropriate than the rat for the prediction of human brain penetration of PF‐05212377, a P‐gp/non‐BCRP substrate.
