The impact of bilingualism on the executive functioning constructs of inhibition, shifting, and updating remains unclear, with prior findings yielding inconsistent results. Several explanations for the lack of congruency have been suggested, including the dependence on observed variables, the impact of test modality on performance, and the need to examine the density of dual languages in the environment. To address these concerns, the current study examined differences between a large group of monolingual (n = 109) and bilingual (n = 152) college students on nonlinguistic behavioral and neural measures of inhibition, shifting, and updating using a latent variable approach. We investigated the impact of test modality by presenting each task in the auditory and visual modalities. Additionally, we examined the effects of language balance and language switching in daily life on the measures of executive functioning. Results revealed greater neural expenditure (i.e., higher ERP amplitude) and weaker performance on tasks assessing response inhibition and shifting abilities in bilinguals. Further, although a neural marker of memory updating did not reveal group differences, performance was stronger in monolinguals. These findings were consistent across test modality. Last, language balance was a stronger predictor of behavioral and neural measures than language switching frequency. Our findings highlight the importance of examining differences at the latent level and exploring the influence of linguistic balance.

Background and aims: The use of e‐cigarettes may influence later smoking uptake in young people. Evidence and gap maps (EGMs) are interactive on‐line tools that display the evidence and gaps in a specific area of policy or research. The aim of this study was to map clusters and gaps in evidence exploring the relationship between e‐cigarette use or availability and subsequent combustible tobacco use in people aged < 30 years. Methods: We conducted an EGM of primary studies and systematic reviews. A framework and an interactive EGM was developed in consultation with an expert advisory group. A systematic search of five databases retrieved 9057 records, from which 134 studies were included. Systematic reviews were appraised using AMSTAR‐2, and all included studies were coded into the EGM framework resulting in the interactive web‐based EGM. A descriptive analysis of key characteristics of the identified evidence clusters and gaps resulted in this report. Results: Studies were completed between 2015 and 2023, with the first systematic reviews being published in 2017. Most studies were conducted in western high‐income countries, predominantly the United States. Cohort studies were the most frequently used study design. The evidence is clustered on e‐cigarette use as an exposure, with an absolute gap identified for evidence looking into the availability of e‐cigarettes and subsequent cessation of cigarette smoking. We also found little evidence analysing equity factors, and little exploring characteristics of e‐cigarette devices. Conclusions: This evidence and gap map (EGM) offers a tool to explore the available evidence regarding the e‐cigarette use/availability and later cigarette smoking in people under the age of 30 years at the time of the search. The majority of the 134 reports is from high‐income countries, with an uneven geographic distribution. Most of the systematic reviews are of lower quality, suggesting the need for higher‐quality reviews. The evidence is clustered around e‐cigarette use as an exposure and subsequent frequency/intensity of current combustible tobacco use. Gaps in evidence focusing on e‐cigarette availability, as well as on the influence of equity factors may warrant further research. This EGM can support funders and researchers in identifying future research priorities, while guiding practitioners and policymakers to the current evidence base. [ABSTRACT FROM AUTHOR]

Aims Methods Results Conclusions To summarise systematic reviews on tobacco addiction published by the Cochrane Tobacco Addiction Group (CTAG) from 2021 to 2023.We identified all new and updated Cochrane Reviews published by CTAG between 2021 and 2023. We present key results from these reviews and discuss promising avenues for future research.CTAG published five new reviews and one overview of reviews, and updated eight reviews. Review evidence showed that all main pharmacotherapies (varenicline, cytisine, bupropion and nicotine replacement therapy [NRT], especially when patches are combined with fast acting forms like gum) are effective for smoking cessation, as are nicotine e‐cigarettes. Evidence suggested similar magnitude of effects of varenicline, cytisine, and nicotine e‐cigarettes; these emerged as the most effective treatments. Evidence also supported behavioural counselling and financial incentives for smoking cessation. Secondary analyses of the Cochrane review of e‐cigarettes for smoking cessation showed over half of participants assigned to e‐cigarette conditions were still using them at six months or longer, that biomarkers of potential harm significantly reduced in people switching from smoking to vaping or to dual use, and that there was insufficient evidence to draw associations between e‐liquid flavours and smoking cessation. Findings on mindfulness‐based interventions, interventions delivered by dental and primary care professionals, interventions to prevent weight gain after smoking cessation, and interventions for waterpipe cessation were less certain. Reviews of observational evidence showed that smoking cessation reduced cardiovascular events and mortality in people living with cardiovascular disease, and improved mental health.Nicotine replacement therapy (especially patches combined with fast acting forms), varenicline, cytisine, bupropion, nicotine e‐cigarettes, behavioural counselling, and financial incentives are all effective ways to help people quit smoking. Quitting smoking improves mental health and reduces cardiovascular events and mortality in people living with cardiovascular disease. [ABSTRACT FROM AUTHOR]

Background: Herpes zoster (shingles) is normally diagnosed clinically. Timely diagnosis is important so that antiviral treatment can be started soon after rash onset. Aim: To assess whether a practice-level educational intervention, aimed at non-clinical patient-facing staff, improves the timely assessment of patients with shingles. Design and setting: This was a cluster randomised study within a trial (SWAT) with nested qualitative study in general practices in England. Method: Practices were cluster randomised 1:1, stratified by centre and minimised by practice list size and Index of Multiple Deprivation score. Intervention practices were sent educational materials, highlighting the common presenting features of shingles and what action to take if suspected. The primary and secondary outcomes were the mean proportion of patients per practice seen within 72 and 144 h of rash onset, respectively. Comparison between groups was conducted using linear regression, adjusting for randomisation variables. Semi-structured interviews with practice staff in intervention practices explored views and opinions about the intervention. Results: In total, 67 practices were enrolled; 34 randomised to the intervention and 33 to the control. The mean difference in proportion of patients seen within 72 and 144 h was −0.132 (95% confidence interval [CI] = −0.308 to 0.043) and −0.039 (95% CI = −0.158 to 0.080), respectively. In intervention practices, 90.9% reported distributing the educational materials; however, engagement with these was suboptimal. Twelve participants were interviewed, and the poster component of the intervention was said to be easiest to implement. Conclusion: Our educational intervention did not improve the timely assessment of patients with shingles. This may be the result of poor intervention engagement. [ABSTRACT FROM AUTHOR]

The university participant pool is a key resource for behavioral research, and data quality is believed to vary over the course of the academic semester. This crowdsourced project examined time of semester variation in 10 known effects, 10 individual differences, and 3 data quality indicators over the course of the academic semester in 20 participant pools (N = 2696) and with an online sample (N = 737). Weak time of semester effects were observed on data quality indicators, participant sex, and a few individual differences—conscientiousness, mood, and stress. However, there was little evidence for time of semester qualifying experimental or correlational effects. The generality of this evidence is unknown because only a subset of the tested effects demonstrated evidence for the original result in the whole sample. Mean characteristics of pool samples change slightly during the semester, but these data suggest that those changes are mostly irrelevant for detecting effects.
