RESUMO
Reducing contributions from non-neuronal sources is a crucial step in functional magnetic resonance imaging (fMRI) connectivity analyses. Many viable strategies for denoising fMRI are used in the literature, and practitioners rely on denoising benchmarks for guidance in the selection of an appropriate choice for their study. However, fMRI denoising software is an ever-evolving field, and the benchmarks can quickly become obsolete as the techniques or implementations change. In this work, we present a denoising benchmark featuring a range of denoising strategies, datasets and evaluation metrics for connectivity analyses, based on the popular fMRIprep software. The benchmark prototypes an implementation of a reproducible framework, where the provided Jupyter Book enables readers to reproduce or modify the figures on the Neurolibre reproducible preprint server (https://neurolibre.org/). We demonstrate how such a reproducible benchmark can be used for continuous evaluation of research software, by comparing two versions of the fMRIprep. Most of the benchmark results were consistent with prior literature. Scrubbing, a technique which excludes time points with excessive motion, combined with global signal regression, is generally effective at noise removal. Scrubbing was generally effective, but is incompatible with statistical analyses requiring the continuous sampling of brain signal, for which a simpler strategy, using motion parameters, average activity in select brain compartments, and global signal regression, is preferred. Importantly, we found that certain denoising strategies behave inconsistently across datasets and/or versions of fMRIPrep, or had a different behavior than in previously published benchmarks. This work will hopefully provide useful guidelines for the fMRIprep users community, and highlight the importance of continuous evaluation of research methods.

BACKGROUND: Increasing the availability of non-alcoholic options is a promising population-level intervention to reduce alcohol consumption, currently unassessed in naturalistic settings. This study in an online retail context aimed to estimate the impact of increasing the proportion of non-alcoholic (relative to alcoholic) drinks, on selection and purchasing of alcohol. METHODS AND RESULTS: Adults (n = 737) residing in England and Wales who regularly purchased alcohol online were recruited between March and July 2021. Participants were randomly assigned to one of 3 groups: "25% non-alcoholic/75% alcoholic"; "50% non-alcoholic/50% alcoholic"; and "75% non-alcoholic/25% alcoholic," then selected drinks in a simulated online supermarket, before purchasing them in an actual online supermarket. The primary outcome was the number of alcohol units selected (with intention to purchase); secondary outcomes included actual purchasing. A total of 607 participants (60% female, mean age = 38 years [range: 18 to 76]) completed the study and were included in the primary analysis. In the first part of a hurdle model, a greater proportion of participants in the "75% non-alcoholic" group did not select any alcohol (13.1%) compared to the "25% non-alcoholic" group (3.4%; 95% confidence interval [CI] -2.09, -0.63; p < 0.001). There was no evidence of a difference between the "75% non-alcoholic" and the "50% non-alcoholic" (7.2%) groups (95% CI 0.10, 1.34; p = 0.022) or between the "50% non-alcoholic" and the "25% non-alcoholic" groups (95% CI -1.44, 0.17; p = 0.121). In the second part of a hurdle model in participants (559/607) selecting any drinks containing alcohol, the "75% non-alcoholic" group selected fewer alcohol units compared to the "50% non-alcoholic" (95% CI -0.44, -0.14; p < 0.001) and "25% non-alcoholic" (95% CI -0.54, -0.24; p < 0.001) groups, with no evidence of a difference between the "50% non-alcoholic" and "25% non-alcoholic" groups (95% CI -0.24, 0.05; p = 0.178). Overall, across all participants, 17.46 units (95% CI 15.24, 19.68) were selected in the "75% non-alcoholic" group; 25.51 units (95% CI 22.60, 28.43) in the "50% non-alcoholic" group; and 29.40 units (95% CI 26.39, 32.42) in the "25% non-alcoholic" group. This corresponds to 8.1 fewer units (a 32% reduction) in the "75% non-alcoholic" compared to the "50% non-alcoholic" group, and 11.9 fewer alcohol units (41% reduction) compared to the "25% non-alcoholic" group; 3.9 fewer units (13% reduction) were selected in the "50% non-alcoholic" group than in the "25% non-alcoholic" group. For all other outcomes, alcohol selection and purchasing were consistently lowest in the "75% non-alcoholic" group. Study limitations include the setting not being entirely naturalistic due to using a simulated online supermarket as well as an actual online supermarket, and that there was substantial dropout between selection and purchasing. CONCLUSIONS: This study provides evidence that substantially increasing the proportion of non-alcoholic drinks-from 25% to 50% or 75%-meaningfully reduces alcohol selection and purchasing. Further studies are warranted to assess whether these effects are realised in a range of real-world settings. TRIAL REGISTRATION: ISRCTN: 11004483; OSF: https://osf.io/qfupw.

BACKGROUND: A natural disaster can have devastating consequences for newborn infants. Despite this fact, there are few studies that have explored household emergency preparedness (HEP) among parents of newborn infants or factors affecting HEP in this population. PURPOSE: The purpose of this study was to explore the relationship between various demographic and socioeconomic variables and levels of HEP among parents of newborn infants. METHODS: Parents of newborn infants born at a single medical center in Brooklyn, New York, completed a pre- and posttest to determine their level of HEP before and after implementing the Nurses Taking on Readiness Measures (N-TORM) intervention. For this study, a secondary statistical analysis was performed on the HEP scores gathered prior to the intervention and the demographic data collected from participants. RESULTS: There was a statistically significant relationship between HEP scores and homeownership t(62) = 2.75, P = .008, level of education t(66) = 2.31, P = .024, and income t(46) = 2.39, P = .021. IMPLICATIONS FOR PRACTICE AND RESEARCH: Findings from this study indicate that there are various demographic and socioeconomic factors that influence HEP. Another critical finding was that most participants were significantly underprepared for an emergency with an average HEP score of 4.75 (SD = 2.61) out of a possible 11 points. Findings from this study support the need for neonatal and pediatric providers to develop targeted interventions to enhance the preparedness of parents of newborns in general, and in particular, those with lower household incomes, lower levels of education, and those who rent their homes.

With the increase in large multimodal cohorts and high-throughput technologies, the potential for discovering novel biomarkers is no longer limited by data set size. Artificial intelligence (AI) and machine learning approaches have been developed to detect novel biomarkers and interactions in complex data sets. We discuss exemplar uses and evaluate current applications and limitations of AI to discover novel biomarkers. Remaining challenges include a lack of diversity in the data sets available, the sheer complexity of investigating interactions, the invasiveness and cost of some biomarkers, and poor reporting in some studies. Overcoming these challenges will involve collecting data from underrepresented populations, developing more powerful AI approaches, validating the use of noninvasive biomarkers, and adhering to reporting guidelines. By harnessing rich multimodal data through AI approaches and international collaborative innovation, we are well positioned to identify clinically useful biomarkers that are accurate, generalizable, unbiased, and acceptable in clinical practice. HIGHLIGHTS: Artificial intelligence and machine learning approaches may accelerate dementia biomarker discovery. Remaining challenges include data set suitability due to size and bias in cohort selection. Multimodal data, diverse data sets, improved machine learning approaches, real-world validation, and interdisciplinary collaboration are required.

Artificial intelligence (AI) and machine learning (ML) approaches are increasingly being used in dementia research. However, several methodological challenges exist that may limit the insights we can obtain from high-dimensional data and our ability to translate these findings into improved patient outcomes. To improve reproducibility and replicability, researchers should make their well-documented code and modeling pipelines openly available. Data should also be shared where appropriate. To enhance the acceptability of models and AI-enabled systems to users, researchers should prioritize interpretable methods that provide insights into how decisions are generated. Models should be developed using multiple, diverse datasets to improve robustness, generalizability, and reduce potentially harmful bias. To improve clarity and reproducibility, researchers should adhere to reporting guidelines that are co-produced with multiple stakeholders. If these methodological challenges are overcome, AI and ML hold enormous promise for changing the landscape of dementia research and care. HIGHLIGHTS: Machine learning (ML) can improve diagnosis, prevention, and management of dementia. Inadequate reporting of ML procedures affects reproduction/replication of results. ML models built on unrepresentative datasets do not generalize to new datasets. Obligatory metrics for certain model structures and use cases have not been defined. Interpretability and trust in ML predictions are barriers to clinical translation.

BACKGROUND: There is ongoing clinical and research interest in determining whether providing personalised risk information could motivate risk-reducing health behaviours. We aimed to assess the impact on behaviours and risk factors of feeding back to individuals' images of their bodies generated via medical imaging technologies in assessing their current disease status or risk. METHODS AND FINDINGS: A systematic review with meta-analysis was conducted using Cochrane methods. MEDLINE, Embase, PsycINFO, CINAHL, and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched up to July 28, 2021, with backward and forward citation searches up to July 29, 2021. Eligible studies were randomised controlled trials including adults who underwent medical imaging procedures assessing current health status or risk of disease, for which personal risk may be reduced by modifying behaviour. Trials included an intervention group that received the imaging procedure plus feedback of visualised results and assessed subsequent risk-reducing health behaviour. We examined 12,620 abstracts and included 21 studies, involving 9,248 randomised participants. Studies reported on 10 risk-reducing behaviours, with most data for smoking (8 studies; n = 4,308), medication use (6 studies; n = 4,539), and physical activity (4 studies; n = 1,877). Meta-analysis revealed beneficial effects of feedback of visualised medical imaging results on reduced smoking (risk ratio 1.11, 95% confidence interval [CI] 1.01 to 1.23, p = 0.04), healthier diet (standardised mean difference [SMD] 0.30, 95% CI 0.11 to 0.50, p = 0.003), increased physical activity (SMD 0.11, 95% CI 0.003 to 0.21, p = 0.04), and increased oral hygiene behaviours (SMD 0.35, 95% CI 0.13 to 0.57, p = 0.002). In addition, single studies reported increased skin self-examination and increased foot care. For other behavioural outcomes (medication use, sun protection, tanning booth use, and blood glucose testing) estimates favoured the intervention but were not statistically significant. Regarding secondary risk factor outcomes, there was clear evidence for reduced systolic blood pressure, waist circumference, and improved oral health, and some indication of reduced Framingham risk score. There was no evidence of any adverse effects, including anxiety, depression, or stress, although these were rarely assessed. A key limitation is that there were some concerns about risk of bias for all studies, with evidence for most outcomes being of low certainty. In particular, valid and precise measures of behaviour were rarely used, and there were few instances of preregistered protocols and analysis plans, increasing the likelihood of selective outcome reporting. CONCLUSIONS: In this study, we observed that feedback of medical images to individuals has the potential to motivate risk-reducing behaviours and reduce risk factors. Should this promise be corroborated through further adequately powered trials that better mitigate against risk of bias, such interventions could usefully capitalise upon the widespread and growing use of medical imaging technologies in healthcare.

AIM: The purpose of this study was to explore resilience among nursing faculty during the COVID-19 pandemic and to examine associations or differences that may exist among variables and between groups. BACKGROUND: Nurse educators' resilience has been identified as an important characteristic because of the challenges involved in nursing education. It is important to explore resilience among nurse educators to determine which factors promote or inhibit this important characteristic. METHOD: This correlational research study used an online survey to explore factors related to resilience among nurse faculty during the COVID-19 pandemic. Correlational analyses were used to determine the relationship between various resilience constructs and select demographic variables. RESULTS: Findings indicated that higher levels of resilience were associated with age (ρ = .21, p < .001), experience teaching online ( r = .22, p < .001), and professional development related to online teaching ( M = 80.7, SD = 11.0), t (276) = 2.41, p = .017. CONCLUSION: Resilience and related characteristics have the potential to assist nurse educators in adapting successfully to stressful circumstances. It is crucial that schools of nursing develop programs to enhance or develop resilience among nurse educators. Support and training in the area of online education are also of paramount importance.

PURPOSE: To evaluate the effectiveness of a nurse-led intervention on the household emergency preparedness (HEP) level of parents with newborns and describe the nurses' perceived facilitators/barriers to providing this intervention. DESIGN: A non-randomized, non-blinded, quasi-experimental pilot study conducted with maternal/child nurses and neonatal parents. The intervention used an educational booklet on what is needed to prepare for disasters and how to develop evacuation and communication plans. Parents completed booklets during their infant's hospital stay, after which they received a free disaster kit from the nurses. SAMPLE: 68 parents, 13 maternal/child nurses. MAIN OUTCOME VARIABLE: Level of HEP. RESULTS: HEP scores increased from 4.75 to 10.66 out of 11 from pre- to post-intervention (p < .001). Barriers to implementing this intervention included the weight of the disaster kit, parent anxiety, and need for follow-up with parents. Facilitators included the booklet, disaster kit, and speed/cost of the intervention.

Increasing the availability of lower-energy foods increases their selection. The current studies examine the extent to which this effect could be mediated by social norms - assessed by perceived popularity of foods - which may be implied by their relative availability. Study 1 (Online): 2340 UK adults estimated the perceived popularity of products. Participants were randomised to see photos of cafeteria shelves varying in the availability of lower-energy options (1/4 lower-energy; 1/2 lower-energy; 3/4 lower-energy) and fullness of shelves (fuller; emptier). Study 2 (Laboratory): 139 English adults were asked to select a snack. Participants were randomised to select from trays varying in the availability of the lower-energy option (1/3 lower-energy; 2/3 lower-energy) and fullness of tray (fuller; emptier). In Study 1, evidence for an interaction was found, such that when shelves were fuller, a higher proportion of lower-energy options led to greater perceived popularity of lower-energy products (1/4 lower-energy: 40.9% (95%CIs: 40.1,41.8); 3/4 lower-energy: 47.2% (46.3,48.0)), whereas when shelves were emptier, a higher proportion of lower-energy options led to lower perceived popularity (1/4 lower-energy: 48.4% (47.5,49.2); 3/4 lower-energy: 39.2% (38.3,40.0)). In Study 2, when the tray was fuller, participants were more likely - albeit non-significantly - to select a lower-energy snack when 2/3 of the available snacks were lower-energy (35.7% (18.5,52.9)) than when 1/3 were lower-energy (15.4% (4.2,26.5)). For emptier trays, lower-energy selections decreased as the relative availability of lower-energy snacks increased (1/3 lower-energy snacks: 36.0% (17.9,54.1); 2/3 lower-energy snacks: 27.8% (13.9,41.7)). These studies provide novel evidence that social norms may mediate the impact of availability on food selection. In addition, they suggest that the effect of availability may be moderated by display layout through its impact on perceived product popularity.

AIMS: Information provided on glass labels may be an effective method to reduce alcohol consumption. The aim of this study was to assess the impact of glass labels conveying unit information and a health warning in reducing ad libitum alcohol consumption. METHODS: A cluster-randomized experimental study was conducted to measure the efficacy of a labeled glass in reducing alcohol consumption in a semi naturalistic bar laboratory setting, in a sample of 81 pairs (n = 162) of UK young adult drinkers. Pairs were randomized to receive two 340-ml glasses of beer or wine: labeled or plain (control). Alcohol consumption was assessed in an ad libitum drinking period, and urge to drink was measured at baseline and postdrinking period. Focus groups (n = 2) were conducted, and thematic analysis was used to gain an insight into the acceptability and the perceived effectiveness of the glasses. RESULTS: Mean unit consumption was 1.62 (SD ± 0.83) units in the labeled glass condition and 1.69 (SD ± 0.82) units in the non labeled glass condition. There were no significant effects of the labeled glasses on ad libitum alcohol consumption (95% CI -0.25 to 0.37, p = 0.35), despite participants (85%) noticing the information. Qualitative analysis of focus groups indicated that although participants perceived the glasses as a useful tool for increasing awareness of units and guidelines, they were viewed as limited in their potential to change drinking behavior due to the unappealing design of the glass and a view that unit guidelines were not relevant to drinking patterns or contexts. CONCLUSIONS: Labeled glasses did not change alcohol consumption in the current study, potentially due to ineffectiveness of this type of message in a young adult population. The information on the glasses was attended to, highlighting that glasses could be a feasible tool for providing information.

BACKGROUND: Health warning labels (HWLs) using images and text to depict the negative health consequences of tobacco consumption are effective and acceptable for changing smoking-related outcomes. There is currently limited evidence concerning their potential use for reducing consumption of alcoholic drinks and energy-dense foods. The aim of this research was to describe the potential effectiveness and acceptability of image-and-text (also known as pictorial or graphic) HWLs applied to: i. alcoholic drinks and ii. energy-dense snack foods. METHODS: Two online studies were conducted using between-subjects designs with general population samples. Participants rated one of 21 image-and-text HWLs on alcoholic drinks (n = 5528), or one of 18 image-and-text HWLs on energy-dense snacks (n = 4618). HWLs comprised a graphic image with explanatory text, depicting, respectively, seven diseases linked to excess alcohol consumption, and six diseases linked to excess energy intake. Diseases included heart disease and various cancers. Outcomes were negative emotional arousal, desire to consume the labelled product, and acceptability of the label. Free-text comments relating to HWLs were content analysed. RESULTS: For both alcoholic drinks and energy-dense snacks, HWLs depicting bowel cancer generated the highest levels of negative emotional arousal and lowest desire to consume the product, but were the least acceptable. Acceptability was generally low for HWLs applied to alcohol, with 3 of 21 rated as acceptable, and was generally high for snacks, with 13 of 18 rated as acceptable. The majority of free-text comments expressed negative reactions to HWLs on alcohol or energy-dense snacks. CONCLUSIONS: Image-and-text health warning labels depicting bowel cancer showed greatest potential for reducing selection and consumption of alcoholic drinks and energy-dense snacks, although they were the least acceptable. Laboratory and field studies are needed to assess their impact on selection and consumption.

Excessive consumption of energy-dense food increases the risk of obesity, which in turn increases the risk of non-communicable diseases, including heart disease, type 2 diabetes and most non-smoking-related cancers. Health warning labels (HWLs) that communicate the adverse health consequences of excess energy consumption could reduce intake of energy-dense foods. The aim of the current study was to estimate the impact on selection of energy-dense snacks of (a) image-and-text HWLs (b) text-only HWLs and (c) calorie information. In a between-subjects, 3 (HWL: image-and-text, text-only, no label) x 2 (calorie information: present, absent), factorial experimental design, participants (N = 4134) were randomised to view a selection of energy-dense and non-energy-dense snacks with one of five label types or no label. The primary outcome was the proportion of participants selecting an energy-dense snack in a hypothetical vending machine task. The proportion of participants selecting an energy-dense snack was reduced in all label groups, relative to the no label group (no label: 59%; calories only: 54%; text-only HWL: 48%; text-only HWL with calories: 44%; image-and-text HWL: 37%; image-and-text HWL with calories: 38%). Compared to the no label group, participants were least likely to select an energy-dense snack in the image-and-text HWL group (OR = 0.46, 95%CI = 0.40, 0.54, p < 0.001). Health warning labels - particularly those including an image and text - have the potential to reduce selection of energy-dense snacks in an online setting. Their impact on selection and consumption in real-world settings awaits testing.

BACKGROUND: There is considerable uncertainty regarding the impact of tableware size on food consumption. Most existing studies have used small and unrepresentative samples and have not followed recommended procedures for randomised controlled trials, leading to increased risk of bias. In the first pre-registered study to date, we examined the impact on consumption of using larger versus smaller plates for self-served food. We also assessed impact on the underlying meal micro-structure, such as number of servings and eating rate, which has not previously been studied. METHODS: The setting was a purpose-built naturalistic eating behaviour laboratory. A general population sample of 134 adult participants (aged 18-61 years) was randomly allocated to one of two groups varying in the size of plate used for self-serving lunch: large or small. The primary outcome was amount of food energy (kcal) consumed during a meal. Additionally, we assessed impact on meal micro-structure, and examined potential modifying effects of executive function, socio-economic position, and sensitivity to perceptual cues. RESULTS: There was no clear evidence of a difference in consumption between the two groups: Cohen's d = 0.07 (95% CI [- 0.27, 0.41]), with participants in the large plate group consuming on average 19.2 (95% CI [- 76.5, 115.0]) more calories (3%) compared to the small plate group (large: mean (SD) = 644.1 (265.0) kcal, versus small: 624.9 (292.3) kcal). The difference between the groups was not modified by individual characteristics. There was no evidence of impact on meal micro-structure, with the exception of more food being left on the plate when larger plates were used. CONCLUSIONS: This study suggests that previous meta-analyses of a low-quality body of evidence may have considerably overestimated the effects of plate size on consumption. However, the possibility of a clinically significant effect - in either direction - cannot be excluded. Well-conducted trials of tableware size in real-world field settings are now needed to determine whether changing the size of tableware has potential to contribute to efforts to reduce consumption at population-level. TRIAL REGISTRATION: The study protocol ( https://osf.io/e3dfh/ ) and data analysis plan ( https://osf.io/sh5u7/ ) were pre-registered on the Open Science Framework.

Inhibitory control refers to the ability to stop, change or delay a response, and is often used in order to protect higher order goals. Theoretical models suggest that appetitive cues such as pictures of alcoholic drinks or food evoke strong automatic appetitive responses which lead to transient impairments in inhibitory control, and that these effects of cues may be related to individual differences (e.g. in body mass index, or alcohol consumption). In order to investigate these claims we conducted a random effects meta-analysis of 66 effect sizes (35 alcohol, 31 food) from 37 articles that tested the effect of exposure to appetitive (alcohol/food) cues on indices of inhibitory control. The overall effect of cue exposure was small, but robust (SMDâ¯=â¯-0.12 [95% CI -0.23, -0.02]; Zâ¯=â¯2.34, pâ¯=â¯.02, I2â¯=â¯84%). Exposure to alcohol-related cues significantly impaired inhibitory control (SMDâ¯=â¯-0.21 [95% CIâ¯=â¯-0.32, -0.11]; Zâ¯=â¯4.17, pâ¯<â¯.001), however exposure to food-related cues did not lead to impairments (SMDâ¯=â¯-0.03 [95% CIâ¯=â¯-0.21, 0.15]; Zâ¯=â¯0.36, pâ¯=â¯.720). There was no evidence that drinking or weight status significantly moderated the effects of cues on inhibitory control. Similarly, cue modality (words, pictures, or smells) did not significantly moderate the effects. Trim and Fill analysis suggested bias in the literature, which when corrected, made the overall effect of cues non-significant. Overall, these findings provide some tentative support for theoretical claims that exposure to appetitive cues prompts transient impairments in inhibitory control. Further research is required to determine the clinical significance of these observations. However, care should be taken when drawing conclusions from a potentially biased evidence base.

ABSTRACT: Perinatal loss, the tragic event of losing a baby before, during, or shortly after birth, is a profoundly distressing experience for any family. We focus on the unique challenges faced by diverse families, encompassing those from underrepresented racial, ethnic, religious, and LGBTQ+ backgrounds. Diverse families often encounter inadequate support, misunderstandings, and even mistreatment during their perinatal loss journeys due to cultural insensitivity and biases. This review underscores the necessity of a trauma-informed, person-centered approach to perinatal bereavement care that respects the diversity of those affected. We emphasize the importance of understanding various cultural perspectives on grief and mortality to provide appropriate and empathetic care.Our core purpose is to elucidate the challenges confronting diverse families dealing with perinatal loss and to offer actionable strategies for health care providers. By addressing these unique challenges, nurses and other health care professionals can offer culturally sensitive, person-centered support during this distressing time. This review can serve as a resource for nurses and other health care providers, enabling them to provide personalized, culturally sensitive care to diverse families experiencing perinatal loss through a trauma-informed lens. Recognizing and addressing these distinctive needs fosters healing and ensures that nurses and other health care providers are better equipped to guide families through the challenging journey of perinatal bereavement.

BACKGROUND: Quality improvement (QI) is an essential part of nursing education. Although there are robust examples of teaching strategies for QI, there is a distinct lack of research on effective strategies for teaching QI in nursing education. METHOD: This multisite study included students from six nursing programs. A treatment fidelity plan was developed and followed to ensure consistency for implementation of the study and data collection. A quasiexperimental, nonpaired, pre- and posttest study design was used to examine changes in student perspectives of QI after participating in a QI teaching strategy. Pre- and posttest questions were mapped to the American Association of Colleges of Nursing's Essentials subcompetency statements for QI. RESULTS: A total of 254 pre- and 116 posttest responses were included for analysis. Significance (p = .05) was found at the beginning level within three questions. CONCLUSION: Findings from this study indicate beginning-level students can benefit from a competency-based QI learning activity. [J Nurs Educ. 2024;63(1):38-42.].

Aim: This research evaluated the effect of a nurse-facilitated intervention on elderly or medically frail community members' level of household emergency preparedness as measured in knowledge, actions taken, and supplies gathered. These community members had access and functional needs that must be accommodated during disasters to mitigate their increased risk of injury, illness, and death because of the disaster. With adequate preparedness, it is plausible these community members may survive the aftermath of a disaster without needing assistance from disaster responders. Methods: This was a non-randomized, single group, before-after feasibility study (N = 31) conducted in a one-on-one session with a nurse interventionist in an urban community setting in the United States of America. We used the Household Emergency Preparedness Instrument to measure intervention effectiveness and a Participant Experience Survey to evaluate participant satisfaction with the intervention. The intervention included an educational booklet that provided instruction to participants on how to create a disaster-related evacuation and communication plan and identify community resources. Upon completion of the booklet, participants received a complimentary disaster supply kit. Results: Mean general preparedness scores increased from 5.5 (SD = 4.1) pre-intervention to 20.2 (SD = 3.1) post-intervention (p < .001). Preparedness in all sub-scales also increased significantly (all ps < .001). Conclusions: Study findings provide support for the feasibility of the intervention to increase all measured aspects of emergency preparedness (knowledge, behaviors, and supplies) among elderly and medically frail adults with access and functional needs during disasters.
RESUMO
AIMS: The study aimed to estimate the impact of introducing a draught alcohol-free beer, thereby increasing the relative availability of these products, on alcohol sales and monetary takings in bars and pubs in England. DESIGN: Randomised crossover field trial. SETTING: England. PARTICIPANTS: Fourteen venues that did not previously sell draught alcohol-free beer. INTERVENTION AND COMPARATOR: Venues completed two intervention periods and two control periods in a randomised order over 8 weeks. Intervention periods involved replacing one draught alcoholic beer with an alcohol-free beer. Control periods operated business as usual. MEASUREMENTS: The primary outcome was mean weekly volume (in litres) of draught alcoholic beer sold. The secondary outcome was mean weekly revenue [in GBP (£)] from all drinks. Analyses adjusted for randomised order, special events, season and busyness. FINDINGS: The adjusted mean difference in weekly sales of draught alcoholic beer was -20 L [95% confidence interval (CI) = -41 to +0.4], equivalent to a 4% reduction (95% CI = 8% reduction to 0.1% increase) in the volume of alcoholic draught beer sold when draught alcohol-free beer was available. Excluding venues that failed at least one fidelity check resulted in an adjusted mean difference of -29 L per week (95% CI = -53 to -5), equivalent to a 5% reduction (95% CI = 8% reduction to 0.8% reduction). The adjusted mean difference in weekly revenue was +61 GBP per week (95% CI = -328 to +450), equivalent to a 1% increase (95% CI = 5% decrease to 7% increase) when draught alcohol-free beer was available. CONCLUSIONS: Introducing a draught alcohol-free beer in bars and pubs in England reduced the volume of draught alcoholic beer sold by 4% to 5%, with no evidence of the intervention impacting net revenue.

AIMS: To estimate the impact on selection and actual purchasing of (a) health warning labels (text-only and image-and-text) on alcoholic drinks and (b) calorie labels on alcoholic and non-alcoholic drinks. DESIGN: Parallel-groups randomised controlled trial. SETTING: Drinks were selected in a simulated online supermarket, before being purchased in an actual online supermarket. PARTICIPANTS: Adults in England and Wales who regularly consumed and purchased beer or wine online (n = 651). Six hundred and eight participants completed the study and were included in the primary analysis. INTERVENTIONS: Participants were randomized to one of six groups in a between-subjects three [health warning labels (HWLs) (i): image-and-text HWL; (ii) text-only HWL; (iii) no HWL] × 2 (calorie labels: present versus absent) factorial design (n per group 103-113). MEASUREMENTS: The primary outcome measure was the number of alcohol units selected (with intention to purchase); secondary outcomes included alcohol units purchased and calories selected and purchased. There was no time limit for selection. For purchasing, participants were directed to purchase their drinks immediately (although they were allowed up to 2 weeks to do so). FINDINGS: There was no evidence of main effects for either (a) HWLs or (b) calorie labels on the number of alcohol units selected (HWLs: F(2,599) = 0.406, P = 0.666; calorie labels: F(1,599) = 0.002, P = 0.961). There was also no evidence of an interaction between HWLs and calorie labels, and no evidence of an overall difference on any secondary outcomes. In pre-specified subgroup analyses comparing the 'calorie label only' group (n = 101) with the 'no label' group (n = 104) there was no evidence that calorie labels reduced the number of calories selected (unadjusted means: 1913 calories versus 2203, P = 0.643). Among the 75% of participants who went on to purchase drinks, those in the 'calorie label only' group (n = 74) purchased fewer calories than those in the 'no label' group (n = 79) (unadjusted means: 1532 versus 2090, P = 0.028). CONCLUSIONS: There was no evidence that health warning labels reduced the number of alcohol units selected or purchased in an online retail context. There was some evidence suggesting that calorie labels on alcoholic and non-alcoholic drinks may reduce calories purchased from both types of drinks.
