Insight into the sorption and desorption pattern of pyrrolizidine alkaloids and their N-oxides in acidic tea (Camellia sinensis) plantation soils.

Pyrrolizidine alkaloids (PAs) and their N-oxides (PANOs) are phytotoxins produced by various plant species and have been emerged as environmental pollutants. The sorption/desorption behaviors of PAs/PANOs in soil are crucial due to the horizontal transfer of these natural products from PA-producing plants to soil and subsequently absorbed by plant roots. This study firstly investigated the sorption/desorption behaviors of PAs/PANOs in tea plantation soils with distinct characteristics. Sorption amounts for seneciphylline (Sp) and seneciphylline-N-oxide (SpNO) in three acidic soils ranged from 2.9 to 5.9 µg/g and 1.7 to 2.8 µg/g, respectively. Desorption percentages for Sp and SpNO were from 22.2% to 30.5% and 36.1% to 43.9%. In the mixed PAs/PANOs systems, stronger sorption of PAs over PANOs was occurred in tested soils. Additionally, the Freundlich models more precisely described the sorption/desorption isotherms. Cation exchange capacity, sand content and total nitrogen were identified as major influencing factors by linear regression models. Overall, the soils exhibiting higher sorption capacities for compounds with greater hydrophobicity. PANOs were more likely to migrate within soils and be absorbed by tea plants. It contributes to the understanding of environmental fate of PAs/PANOs in tea plantations and provides basic data and clues for the development of PAs/PANOs reduction technology.

Barrierless reactions of C2 Criegee intermediates with H2SO4 and their implication to oligomers and new particle formation.

The formation of oligomeric hydrogen peroxide triggered by Criegee intermediate maybe contributes significantly to the formation and growth of secondary organic aerosol (SOA). However, to date, the reactivity of C2 Criegee intermediates (CH3CHOO) in areas contaminated with acidic gas remains poorly understood. Herein, high-level quantum chemical calculations and Born-Oppenheimer molecular dynamics (BOMD) simulations are used to explore the reaction of CH3CHOO and H2SO4 both in the gas phase and at the air-water interface. In the gas phase, the addition reaction of CH3CHOO with H2SO4 to generate CH3HC(OOH)OSO3H (HPES) is near-barrierless, regardless of the presence of water molecules. BOMD simulations show that the reaction at the air-water interface is even faster than that in the gas phase. Further calculations reveal that the HPES has a tendency to aggregate with sulfuric acids, ammonias, and water molecules to form stable clusters, meanwhile the oligomerization reaction of CH3CHOO with HPES in the gas phase is both thermochemically and kinetically favored. Also, it is noted that the interfacial HPES- ion can attract H2SO4, NH3, (COOH)2 and HNO3 for particle formation from the gas phase to the water surface. Thus, the results of this work not only elucidate the high atmospheric reactivity of C2 Criegee intermediates in polluted regions, but also deepen our understanding of the formation process of atmospheric SOA induced by Criegee intermediates.

Terapia de Aceptación y Compromiso en conducta suicida: una revisión sistemática / Acceptance and Commitment Therapy on suicidal behavior: a systematic review

El suicidio se ha convertido en un problema social y de salud pública a nivel mundial. En este sentido, la Terapia de Aceptación y Compromiso (ACT) podría ser eficaz en su abordaje, existiendo evidencia sobre la relación entre algunos de sus componentes y la conducta suicida. Así, el presente estudio tuvo por objetivo realizar una revisión sistemática sobre la eficacia de ACT en conducta suicida. Para ello se siguió el protocolo PRISMA, empleando las siguientes bases de datos: PsycInfo, PubMed, Scopus y PsicoDoc. Inicialmente se obtuvieron 108 publicaciones potencialmente relevantes, de las cuales, finalmente, 13 fueron incluidas en la revisión. La calidad de los estudios se analizó a través de un instrumento de evaluación de riesgo de sesgos. Como resultados, a nivel general se observaron disminuciones estadísticamente significativas en ideación suicida (IS) y factores de riesgo de suicidio. Además, algunos estudios señalaron relaciones estadísticamente significativas entre un aumento de flexibilidad psicológica y la disminución de IS. Si bien los datos apuntaron a una posible eficacia de ACT en la reducción de IS, es necesario llevar a cabo mayor número de estudios experimentales que contemplen la complejidad de la conducta suicida y exploren los procesos de cambio implicados.(AU)

Executive functions in psychopathy: a meta-analysis of inhibition, planning, shifting, and working memory performance.

Much research has focused on executive function (EF) impairments in psychopathy, a severe personality disorder characterized by a lack of empathy, antisocial behavior, and a disregard for social norms and moral values. However, it is still unclear to what extent EF deficits are present across psychopathy factors and, more importantly, which EF domains are impaired. The current meta-analysis answers these questions by synthesizing the results of 50 studies involving 5,694 participants from 12 different countries. Using multilevel random-effects models, we pooled effect sizes (Cohen's d) for five different EF domains: overall EF, inhibition, planning, shifting, and working memory. Moreover, differences between psychopathy factors were evaluated. Our analyses revealed small deficits in overall EF, inhibition, and planning performance. However, a closer inspection of psychopathy factors indicated that EF deficits were specific to lifestyle/antisocial traits, such as disinhibition. Conversely, interpersonal/affective traits, such as boldness, showed no deficits and in some cases even improved EF performance. These findings suggest that EF deficits are not a key feature of psychopathy per se, but rather are related to antisociality and disinhibitory traits. Potential brain correlates of these findings as well as implications for future research and treatment are discussed.

Impact of the COVID-19 Pandemic on Foodborne Disease Healthcare-Seeking Behavior and Diagnoses at a Large Academic Medical System.

The objective of this study was to examine changes in healthcare-seeking behaviors and diagnostic practices around foodborne illness during the COVID-19 pandemic in a large university-based health system. A retrospective cohort study of individuals diagnosed with pathogens commonly transmitted through food between 2015 and 2020 was undertaken using electronic medical record data. Regression models were used to compare measured incidence rates of various foodborne pathogens as well as associated healthcare-seeking behaviors during the pandemic year of 2020 to previous years. Incidence of campylobacteriosis, cholera, and norovirus in 2020 significantly decreased, respectively, by 65.5% (p < 0.01), 90.1% (p = 0.02), and 73.0% (p = 0.03) compared with an average from 2017- to 019. Average annual visits for patients included in our sample significantly increased by 8.0% when comparing the average from 2017-2019 to 2020 (p < 0.01). These results suggest that the pandemic impacted healthcare use related to foodborne disease either due to reduced exposure to foodborne pathogens or reduced willingness to seek healthcare.

Evaluations of aggressive chasing interactions by 7-month-old infants.

Recent theories of socio-moral development assume that humans evolved a capacity to evaluate others' social actions in different kinds of interactions. Prior infant studies found both reaching and visual preferences for the prosocial over the antisocial agents. However, whether the attribution of either positive or negative valence to agents' actions involved in an aggressive chasing interaction can be inferred by both reaching behaviors and visual attention deployment (i.e., disengagement of visual attention) is still an open question. Here we presented 7-month-old infants (N = 92) with events displaying an aggressive chasing interaction. By using preferential reaching and an attentional task (i.e., overlap paradigm), we assessed whether and how infants evaluate aggressive chasing interactions. The results demonstrated that young infants prefer to reach the victim over the aggressor, but neither agent affects visual attention. Moreover, such reaching preferences emerged only when dynamic cues and emotional face-like features were congruent with agents' social roles. Overall, these findings suggested that infants' evaluations of aggressive interactions are based on infants' sensitivity to some kinematic cues that characterized agents' actions and, especially, to the congruency between such motions and the face-like emotional expressions of the agents.

Oral health, treatment burden and demographics of elders with care-resistant behavior: A cross-sectional study.

AIMS: To assess oral health, treatment burden, mortality risk, and demographics in elders with care-resistant behaviors (CRB) in nursing homes (NH) and compare them with those without CRB. METHODS AND RESULTS: 503 participants from eight NH who received dental treatment through a mobile dental clinic were included. Their medical and dental records were screened regarding oral/dental health, treatment history, general health, demographics, and CRB. Statistical analysis was performed to show correlations between CRB and the measured parameters. Data were verified for normal distribution; a point-biserial correlation model was used (95% CI: α = 0.05). No correlation was found between CRB and Decayed Missing Filled Teeth (DMF-T) (rpb = -0.061, p = .177), as well as periodontal status (rpb = 0.004, p = .946). A negative correlation was observed between CRB and the required number of treatment procedures (rpb = -0.181, p < .0001), time (rpb = -0.118, p = .010), and costs (rpb = -0.100, p = .028). Sex predilection for men regarding CRB was evident (rpb = -0.155, p = .01). No correlation appeared between CRB and vital status (rpb = -0.41, p = .355). CONCLUSION: Oral health seems to be similar in institutionalized elders with or without CRB. Treatment burden was not elevated, but even reduced in elders with CRB, evincing that few/no treatment procedures were performed in those elders. CRB demonstrated a sex predilection for men. An association between CRB and increased mortality was not evident.

Multimodal Cues to Change Your Mind: The Intertwining of Faces, Voices, and Behaviors in Impression Updating.

Impressions of others are formed from multiple cues, including facial features, vocal tone, and behavioral descriptions, and may be subject to multimodal updating. Four experiments (N = 803) examined the influence of a target's face or voice on impression updating. Experiments 1a-1b examined whether behavior-based impressions are susceptible to updating by incongruent information conveyed by the target's face, voice, or behavior (within-participant manipulation). Both faces and voices updated impressions with comparable strength, but less than behaviors. Experiment 2, contrasting faces and voices only (between-participants manipulation), showed that voices outperformed faces regardless of how impressions were formed (i.e., via behavioral vs. nonbehavioral information). Experiment 3 found no difference when comparing faces and voices in a within-participant design and controlling for stimulus attractiveness. Our work highlights the importance of multimodal cues for impression updating and shows that the relative power of faces and voices depends on contextual factors.

Active longevity and aging: dissecting the impacts of physical and sedentary behaviors on longevity and age acceleration.

BACKGROUND: To examine the associations of physical activity (PA) and sedentary behavior (SB) with longevity and age acceleration (AA) using observational and Mendelian randomization (MR) studies, and quantify the mediating effects of lipids. METHODS: In Guangzhou Biobank Cohort Study (GBCS), PA and SB were assessed by the Chinese Version of the International Physical Activity Questionnaire. Longevity was defined as participants whose age at follow-up or at death was at or above the 90th age percentile. AA was defined as the residual resulting from a linear model that regressed phenotypic age against chronological age. Linear regression and Poisson regression with robust error variance were used to assess the associations of total and specific PA in different intensities, and SB with AA and longevity, yielding ßs or relative risks (RRs) and 95% confidence intervals (CIs). Two-sample MR was conducted to examine the causal effects. Mediation analysis was used to assess the mediating effects of lipids. RESULTS: Of 20,924 participants aged 50 + years in GBCS, during an average follow-up of 15.0 years, compared with low PA, moderate and high PA were associated with higher likelihood of longevity (RR (95% CI): 1.56 (1.16, 2.11), 1.66 (1.24, 2.21), respectively), and also cross-sectionally associated with lower AA (ß (95% CI): -1.43 (-2.41, -0.45), -2.09 (-3.06, -1.11) years, respectively). Higher levels of moderate PA (MPA) were associated with higher likelihood of longevity and lower AA, whereas vigorous PA (VPA) showed opposite effects. The association of PA with longevity observed in GBCS was mediated by low-density lipoprotein cholesterol (LDL-C) by 8.23% (95% CI: 3.58-39.61%), while the association with AA was mediated through LDL-C, triglycerides and total cholesterol by 5.13% (3.94-7.30%), 7.81% (5.98-11.17%), and 3.37% (2.59-4.80%), respectively. Additionally, in two-sample MR, SB was positively associated with AA (ß (95% CI): 1.02 (0.67, 1.36) years). CONCLUSIONS: PA showed protective effects on longevity and AA, with the effects being partly mediated through lipids. Conversely, SB had a detrimental impact on AA. MPA was associated with higher likelihood of longevity and reduced AA, whereas VPA showed adverse effects. Our findings reinforce the recommendation of "sit less and move more" to promote healthy longevity, and highlight the potential risks associated with VPA in the elderly.

The SMILE scale: a wellness behavioral tool for patients with cancer.

PURPOSE: As cancer survivorship increases, there is a need for simple tools to measure and promote healthy behaviors. We created a wellness behavioral tool (the SMILE Scale) to encourage self-monitoring of wellness behaviors. This study aimed to determine the feasibility of collecting daily self-reported SMILE Scale data and weekly quality of life data among patients with cancer. We also aimed to measure the association between SMILE Scale responses and validated health-related quality of life (HRQOL) tools (PROMIS-29 + 2 and SymTrak-8) as a pilot test of the hypothesis that increased wellness behaviors may impact quality of life. METHODS: We surveyed 100 patients with cancer at the Indiana University Simon Comprehensive Cancer Center. Participants were asked to complete daily SMILE Scale assessments over a two-week period, as well as weekly PROMIS-29 + 2 and SymTrak-8 surveys. The primary endpoint was the SMILE Scale completion rate. Secondary endpoints in this single-arm pilot study included correlations between the SMILE Scale and other HRQOL tools. RESULTS: Daily completion rate of the SMILE Scale ranged from 57% to 65% of participants over a 14-day period. Among the 61% of participants who completed SMILE on day 1, 87% completed SMILE on 10 of 14 days. By end of study, participants who self-reported more wellness behaviors (i.e., higher daily SMILE scores) demonstrated significantly higher PROMIS physical health (p = 0.003), higher PROMIS mental health (p = 0.008), and lower (better) SymTrak total symptom burden (p = 0.006). Further, among those who completed at least 1 of 14 daily SMILE assessments, quality of life significantly improved over the two-week period for PROMIS mental health (p = 0.018) and SymTrak total symptom burden (p = 0.014). CONCLUSION: The SMILE Scale completion rate did not satisfy our pre-planned ≥70% threshold for feasibility; however, the rate for completing SMILE at least once during the 14 days (77%) met this threshold. Participants with higher average daily SMILE scores had significantly better scores across other validated HRQOL tools. While these results may be correlative and not causative, this suggests a potential physical and mental health benefit for delivering the SMILE Scale in clinical practice to help encourage healthy behaviors and warrants testing the SMILE Scale's impact in future studies.

A conserved protein family in mirid bug Riptortus pedestris plays dual roles in regulating plant immunity.

The mirid bug (Riptortus pedestris), a major soybean pest, migrates into soybean fields during the pod filling stage and causes staygreen syndrome, which leads to substantial yield losses. The mechanism by which R. pedestris elicits soybean (Glycine max) defenses and counter-defenses remains largely unexplored. In this study, we characterized a protein family from R. pedestris, designated Riptortus pedestris HAMP 1 (RPH1) and its putative paralogs (RPH1L1, 2, 3, 4, and 5), whose members exhibit dual roles in triggering and inhibiting plant immunity. RPH1 and RPH1L1 function as herbivore-associated molecular patterns (HAMPs), activating pattern-triggered immunity (PTI) in tobacco (Nicotiana benthamiana) and G. max. Furthermore, RPH1 stimulates jasmonic acid and ethylene biosynthesis in G. max, thereby enhancing its resistance to R. pedestris feeding. Additionally, RPH1 homologs are universally conserved across various herbivorous species, with many homologs also acting as HAMPs that trigger plant immunity. Interestingly, the remaining RPH1 putative paralogs (RPH1L2-5) serve as effectors that counteract RPH1-induced PTI, likely by disrupting the extracellular perception of RPH1. This research uncovers a HAMP whose homologs are conserved in both chewing and piercing-sucking insects. Moreover, it unveils an extracellular evasion mechanism utilized by herbivores to circumvent plant immunity using functionally differentiated paralogs.

Processing of Sedentary Time and Its Reference Equation in Patients with COPD.

Purpose: Sedentary time (ST) is associated with mortality independent of moderate-to-vigorous physical activity in patients with COPD. The proper processing methods for the measurement data and factors related to ST are still unknown. We investigated several conditions for determining the proper processing of ST accelerometric data and created a reference equation for ST using ST-related factors. Patients and Methods: In Study 1, we evaluated the minimum required number of days to obtain repeatability at different measurement times and assessed the effects of rainy days or weekend days on ST in patients with COPD. In Study 2, we detected the ST-related factors among 28 parameters and created a reference equation for ST using the detected factors. Results: In Study 1, 38 patients with stable COPD were analyzed. The minimum number of days required for repeatability was 3 for 8-h wearing and 2 for 10-h wearing. The ST was significantly prolonged on rainy days, but not on weekends. In Study 2, 216 patients with stable COPD were analyzed. BMI, FEV1%pred, 6MWD, and mMRC were detected as ST-related factors, and a reference equation could be created using these four factors. The equation was validated for patients whose ST was ≥ 6 h. Conclusion: By using properly processed measurement data of ST, we created a reference equation for assessing ST that is expected to be useful for providing individual guidance on the shortening of ST to patients with COPD.

When measuring sedentary time (ST) objectively, we should recognize that the minimum required number of days is three and that ST is prolonged on rainy days. The reference equation for ST could be created using four ST-related factors. It might serve as a guide for shortening ST in COPD.

Using an interactive web application to identify pre-exposure prophylaxis adherence among men who have sex with men.

Background: Men who have sex with men (MSM) are at a high risk for HIV infection. While pre-exposure prophylaxis (PrEP) is an effective oral preventive strategy, its success is largely dependent on consistent medication adherence. Objective: The aim of this study was to develop the machine learning web application and evaluate the performance in predicting PrEP adherence. Methods: The PrEP prospective cohort study of the MSM population conducted in Western China from 2019 to 2023, and we collected adherence data and personal characteristics data from 747 MSM. Predictor variables were screened and the performance of several machine learning methods in predicting nonadherent behaviors were compared. Results: A total of 11 candidate variables were screened that predicted nonadherent behaviors. We developed and evaluated five machine learning models that performed well in predicting adherence. Attitudes of male sexual partners, self-efficacy, HIV testing, number of male sexual partners, and risk perception were the most important predictors of adherence. The optimal prediction model was displayed in a shiny web application for online calculation of the probability of occurrence of nonadherent behaviors among MSM. Conclusions: Machine learning performed well in predicting nonadherent behaviors among MSM. An interactive and intuitive web application can help identify individuals who may have nonadherent behaviors, resulting in improved medication adherence and increased prevention efficacy.

Factors Affecting on Environmental Strategy in SMEs manufacturing Firms of a developing country: Mediating role of Green Employee Behavior.

Background: Sustainability in small and medium-sized enterprises (SMEs) which engage heavily in manufacturing provides them with an essential platform for implementing environmental strategy, which is aimed at reducing environmental damage and promoting environmental protection. This study aims to examine the impact of the reduction in resource use, the greening of processes and products on environmental strategy and the mediating role of green employee behaviour. Methods: Primary data gathered with the help of questionnaires from employees of SMEs manufacturing in developing countries, Pakistan. The research gathered data from 211 participants by applying a pre-tested instrumental questionnaire and structural equation modelling (SEM) for data analysis. Results: The results confirmed all direct effects, including a reduction in resource use, the greening of processes and products and green employee behaviour of environmental strategies in small and medium manufacturing firms. Also, confirmed partial mediation effect of green employee behavior between greening of processes and products and environmental strategy. Conclusion: The current study clearly showed the need for programs and infrastructures that support resource reduction and greening businesses in SMEs. Companies' implementation of green processes and technologies allows SMEs to take an environmentally responsible stand and become part of the movement toward sustainability. The research stresses the importance of green employee conduct as a mediator, the central point being the individual employee being engaged and aware of the subject and willing to participate in environmentally friendly practices. Therefore, small and medium enterprises should enlighten their staff to practice green behaviour, give them what they need and empower them to be change drivers that will trigger sustainability throughout the organisations.

Cross-lagged analysis of social support, physical activity behavior, and family relationships among university students.

Objective: To explore the causal relationship between social support, physical activity behavior, and family relationships among university students. Methods: Using the Social Support Rating Scale, the Physical Activity Behavior Self-Assessment Scale, and the Family Relationships Scale, a longitudinal follow-up survey was conducted on 412 college students in Sichuan Province at 2-month intervals in March 2024 (T1) and May 2024 (T2), to analyze the interaction mechanisms between college students' social support, physical activity behaviors, and family relationships through cross-lagging. Results: (1) There are significant gender differences in social support, physical activity behavior, and family relationships among college students. Among the cross-lagged paths found, except for the path from T1 social support to T2 family relationships (ß: 0.40 > 0.21), all other cross-lagged paths are smaller for female college students compared to male college students; (2) T1 social support was able to positively predict T2 physical activity behaviors (ß = 0.50, p < 0.001), and T1 physical activity behavior can also positively predict T2 social support (ß = 0.18, p < 0.01), but the path value T1 social support → T2 physical activity behavior is larger than T1 physical activity behavior → T2 social support. Therefore, social support is a causal variable for physical activity behavior; (3) T1 social support positively predicts T2 family relationships (ß = 0.26, p < 0.001); (4) T1 family relationships positively predict T2 physical activity behavior (ß = 0.30, p < 0.001). (5) Physical activity behavior is a mediating variable between family relationships and social support, with a mediating effect size of 0.054. Conclusion: There are gender differences in social support, physical activity behavior, and family relationships among college students; there is a longitudinal causal relationship between social support, physical activity behavior, and family relationships; social support is a causal variable of physical activity behavior, and social support is also a causal variable of family relationships, and family relationships are the Social support is a causal variable for physical activity behavior, social support is also a causal variable for family relations, and family relations are a causal variable for physical activity behavior, which has a partially mediating role in family relations and social support.

Basic human values and the adoption of cryptocurrency.

Cryptocurrency is an attempt to create an alternative to centralized financial systems using blockchain technology. However, our understanding of the psychological mechanisms that drive cryptocurrency adoption is limited. This study examines the role of basic human values in three stages of cryptocurrency adoption-awareness, intention to buy, and ownership-using the Theory of Planned Behavior (TPB). Logistic regression analysis was conducted on a quota sample of 714 German adults, and the results showed that openness-to-change values increased the likelihood of cryptocurrency awareness, while self-enhancement values increased the likelihood of intention to buy and ownership. These findings were consistent even after controlling for demographic characteristics, attitudinal beliefs, and perceived behavioral control, which are important factors in the TPB. The results suggest that basic human values may influence an individual's decision to adopt cryptocurrency, but the transition from awareness to ownership may be influenced by socio-economic opportunities available to interested individuals.

High socioeconomic impact on prescription behavior despite unrestricted access to disease-modifying therapies in people with multiple sclerosis.

Background: Economic and health care restraints strongly impact on drug prescription for chronic diseases. We aimed to identify potential factors for prescription behavior in chronic disease. Multiple sclerosis was chosen as a model disease due to its chronic character, incidence, and high socioeconomic impact. Methods: Germany was used as a model country as the health-care system is devoid of economic and drug availability restraints. German statutory health insurance data were analyzed retrospectively. The impact of number of university hospitals and neurologists as well as the gross domestic product (GDP) as potential factors on prescriptions of platform and high-efficacy disease-modifying therapies (DMTs) was analyzed. Results: Prescription of platform DMTs increased over time in almost all federal states with varying degree of increase. Univariate regression analysis showed that the prescription volume of platform DMTs positively correlated with the number of university hospitals and neurologists, as well as the GDP per federal state. Stepwise forward regression analysis including all potential factors indicated a statistically significant model for platform DMT (R2 = 0.55; 95%-CI [0.28, 0.82]; p=0.001) revealing GDP as the main contributor. This was confirmed in the independent analysis. Conclusion: This study illustrates that even without overt drug prescription inequity, access to medication is not evenly distributed and depends on economic strength and regional medical care density.

Post-stroke lateropulsion in Australia and New Zealand: a survey investigating current knowledge, priorities and practice.

BACKGROUND: Post-stroke lateropulsion is prevalent and associated with poor rehabilitation outcomes, but evidence to guide rehabilitation of affected stroke survivors is limited. Current post-stroke lateropulsion rehabilitation practice across Australia and New Zealand has not been previously described. OBJECTIVES: This study aimed to describe lateropulsion rehabilitation practice in Australia and New Zealand, determine clinicians,' educators' and researchers' opinions about the need for educational resources to guide best-practice, and to identify current barriers to, and enablers of, optimal rehabilitation delivery. METHODS: This cross-sectional survey was distributed to stroke rehabilitation clinicians, educators and researchers across Australia and New Zealand using Qualtrics. Data were described using frequency distributions and Chi-squared tests. Responses to open-ended questions were summarized for reporting. RESULTS: The final analyses included 127 surveys. Most participants (93%) were physiotherapists. The importance of identifying and assessing post-stroke lateropulsion was noted by 97.6% of participants; however routine lateropulsion assessment was reported by only 60.6% of respondents. About 93.6% of participants indicated that lateropulsion should be targeted as a rehabilitation priority. Limitations in knowledge and skill among clinicians and insufficient evidence to guide rehabilitation were noted as barriers to best-practice rehabilitation delivery. Most respondents (95.2%) indicated that lateropulsion management should be included in stroke rehabilitation guidelines. CONCLUSIONS: A sample of clinicians, educators, and researchers involved in stroke rehabilitation across Australia and New Zealand have indicated that lateropulsion should be targeted as a rehabilitation priority. Knowledge and skill were identified as barriers to best-practice rehabilitation implementation, which could be improved by addressing lateropulsion in clinical practice guidelines.

Does cognitive control mediate the relationship between peer presence and adolescent risk-taking? An ERP study.

Peer presence influences risk-taking behavior, particularly in adolescence. Based on the dual system model, this event-related potential study examined whether and how the presence of a peer displayed a preference for risky behavior would increase adolescents' risk-taking by disrupting their cognitive control processes in either emotional or non-emotional contexts. A sample of 106 adolescents (17-19 years of age) completed two Stoop tasks and a Balloon Analog Risk Task under three peer presence conditions. Results revealed that compared to other conditions, the presence of a risk-averse peer caused adolescents to make safer decisions through improving their conflict monitoring (more negative N200-diff), whereas a risk-preference peer's presence led adolescents to more risky decisions through disrupting their conflict resolution (more positive N450-diff) but they were only observed on the Emotional Stroop task. These findings suggest that different peer presence contexts could increase or decrease adolescents' risk-taking behaviors by influencing their cognitive control under an emotional context rather than in a non-emotional context.
