The Impact

Behavioral insights or nudges have yielded great benefits for toda's public administrators by improving the quality of official messages and increasing revenue flows. In the absence of a large number of studies suitable for meta-analysis, less is known about the external validity of these interventions, their range of impact, and the exact matching of the behavioral cue to the client group and context. Factorial designs and repeated interventions, as in the study reported in this article, can add insight through respectively comparing interventions and analyzing their impacts over time. This randomized controlled trial tests whether simplification and/or a descriptive social norm can increase payment of local taxes in a central London local authority. In the first wave, a factorial design on a targeted group of residents, simplification increased the number of people paying by four percentage points, whereas the social norm did not change behavior. In wave two of the study, which was carried out across all households, the descriptive social norm backfired, reducing the rate of payment. The heterogeneous nature of the target population and the exact wording of the social norm are discussed as possible reasons for these results.

ABSTRACTBackground:Interventions to support and skill paid home carers and managers could potentially improve health and well-being of older home care clients. This is the first systematic review of interventions to improve how home carers and home care agencies deliver care to older people, with regard to clients’ health and well-being and paid carers’ well-being, job satisfaction, and retention.Methods:We reviewed 10/731 papers found in the electronic search (to January 2016) fitting predetermined criteria, assessed quality using a checklist, and synthesized data using quantitative and qualitative techniques.Results:Ten papers described eight interventions. The six quantitative evaluations used diverse outcomes that precluded meta-analysis. In the only quantitative study (a cluster Randomized Controlled Trial), rated higher quality, setting meaningful goals, carer training, and supervision improved client health-related quality of life. The interventions that improved client outcomes comprised training with additional implementation, such as regular supervision and promoted care focused around clients’ needs and goals. In our qualitative synthesis of four studies, intervention elements carers valued were greater flexibility to work to a needs-based rather than a task-based model, learning more about clients, and improved communication with management and other workers.Conclusions:There is a dearth of evidence regarding effective strategies to improve how home care is delivered to older clients, particularly those with dementia. More research in this sector including feasibility testing of the first home care intervention trials to include health and life quality outcomes for clients with more severe dementia is now needed.

UNSTRUCTURED The World Health Organization named the phenomenon of misinformation spread through the social media “infodemics”, and recognized the need to curb it. Misinformation infodemics undermine not only population safety, but also compliance to the suggestions/prophylactic measures recommended in pandemics. The aim of this study was to review the impact of social media on general population fear in “infoveillance” studies during the COVID-19 pandemic. PRISMA protocol was followed and six out of twenty studies were retrieved, meta-analyzed, and had their findings presented in the form of a Forest plot. The summary random and significant event rate was 0.298, 95% CI respectively 0.213 and 0.400, suggesting that social media-circulated misinformation related to COVID-19 triggered public fear and other manifestations. These findings merit special attention by public health authorities. Thus, “infodemiology” and Infoveillance are valid tools in the hands of epidemiologists to help prevent dissemination of false information, with potentially damaging effects.

The Impact

The evaluation of food intake in older subjects is crucial in order to be able to verify adherence to nutritional recommendations. In this context, estimation of the intake of specific dietary bioactives, such as polyphenols, although particularly challenging, is necessary to plan possible intervention strategies to increase their intake. The aims of the present study were to: (i) evaluate the nutritional composition of dietary menus provided in a residential care setting; (ii) estimate the actual intake of nutrients and polyphenols in a group of older subjects participating in the MaPLE study; and (iii) investigate the impact of an eight-week polyphenol-rich dietary pattern, compared to an eight-week control diet, on overall nutrient and polyphenol intake in older participants. The menus served to the participants provided ~770 mg per day of total polyphenols on average with small variations between seasons. The analysis of real consumption, measured using weighed food diaries, demonstrated a lower nutrient (~20%) and polyphenol intake (~15%) compared to that provided by the menus. The feasibility of dietary patterns that enable an increase in polyphenol intake with putative health benefits for age-related conditions is discussed, with a perspective to developing dietary guidelines for this target population.

This study analyzes the impact of the local crime environment on the likelihood of a firm engaging in financial misconduct. Using the Benford Score metric, which assesses the extent to which a firm’s financial statement number distribution diverges from a theoretical distribution, I find that firms headquartered in high crime areas are associated with greater financial misconduct. The link is more pronounced in firms that offer more stock-based executive compensation to their executives or practice weak corporate governance, and change in the crime rate is associated with change in the firm’s financial misconduct. My results support the social norm, social learning, and environmental criminology theories, as well as the fraud triangle, and are robust to a number of alternative specifications and approaches. The evidence implies that a firm’s environment influences the level of corporate financial misconduct.

Abstract Background This meta-analysis was conducted to evaluate the impact of perioperative use of beta-blocker (BB) on postoperative atrial fibrillation (POAF) after cardiac surgery other than isolated coronary artery bypass grafting (CABG). Methods Five online databases were searched. Studies were included if they (1) enrolled patients who underwent cardiac surgery other than isolated CABG and (2) demonstrated the impact of perioperative use of BB on POAF based on the randomized controlled trial or adjusted analysis. The primary outcome was the occurrence rates of POAF after cardiac surgery. A meta-regression and subgroup analysis were performed according to the proportion of patients with cardiac surgery other than isolated CABG and the timing of BB use, respectively. Results Thirteen articles (5 randomized and 8 nonrandomized studies: n = 25,496) were selected. Proportion of enrolled patients undergoing cardiac surgery other than isolated CABG ranged from 7 to 100%. The BBs were used in preoperative, postoperative, and both periods in 5, 5, and 3 studies, respectively. The pooled analyses showed that the risk of POAF was significantly lower in patients with perioperative BB than those without (odds ratio, 95% confidence interval = 0.56, 0.35–0.91 and 0.70, 0.55–0.91 in randomized and nonrandomized studies, respectively). The risk of POAF was lower in the BB group irrespective of the proportion of nonisolated CABG. Benefit regarding in-hospital mortality was inconclusive. Perioperative stroke and length of stay were not significantly different between BB and non-BB groups. Conclusions Perioperative use of BB is effective in preventing POAF even in patients undergoing cardiac surgery other than isolated CABG, although it did not translate into improved clinical outcomes.

Vein Harvesting

Since the introduction of the saphenous vein graft (SVG) for coronary artery bypass grafting (CABG) in 19621, the SVG has remained the most commonly used conduit to the non-LAD territories for more than half a century. However, several issues surrounding the use of SVGs, including higher graft occlusion rates and wound complications from the harvesting process, have been identified in clinical practice. As such, significant interest has been dedicated towards developing harvesting techniques that minimize the risk of these acute and late complications. In this issue of the Journal of Cardiac Surgery, Yokoyama and colleagues compared the impact of open vein harvesting (OVH), endoscopic vein harvesting (EVH) and no-touch vein harvesting (NT) on all-cause mortality, revascularization and graft failure, using a network meta-analysis based on randomized controlled trials and propensity-score matched studies. The results showed that the risk of graft failure was approximately halved amongst patients receiving NT compared with EVH and OVH; importantly, though, NT was not associated with lower all-cause mortality or revascularization risk. To further examine whether the use of NT grafts endow patients with better long-term clinical outcomes, such as mortality, myocardial infarction, and revascularization rates, a large-scaled randomized controlled trial or a patient-level combined meta-analysis is required.

The Impact

Background The increasing number of internet users presents an opportunity to deliver health interventions to large populations. Despite their potential, many web-based interventions, including those for smoking cessation, face high rates of attrition. Further consideration of how intervention features impact attrition is needed. Objective The aim of this systematic review is to investigate whether tailored web-based smoking cessation interventions for smokers are associated with reduced rates of attrition compared with active or passive untailored web-based interventions. The outcomes of interest were dropout attrition at 1-, 3-, 6-, and 12-month follow-ups. Methods Literature searches were conducted in May 2018 and updated in May 2020 on MEDLINE (Medical Literature Analysis and Retrieval System Online), PsycINFO (Psychological Information), EMBASE (Excerpta Medica dataBASE), CINAHL (Cumulated Index to Nursing and Allied Health Literature), Scopus, and the Cochrane Tobacco Addiction Group Specialized Register with the following search terms: smoking cessation, tailored, or web- or internet-based. Included studies were published in English before or in May 2020 using a randomized controlled trial design. Studies were restricted to those with web-based delivery, a tailored intervention group, an untailored control group, and a reported outcome of smoking cessation. Studies were assessed for methodological quality using the Cochrane Risk of Bias tool. Two reviewers independently extracted the study characteristics and the number of participants lost to follow-up for each treatment group. Results A total of 13 studies were included in the systematic review, of which 11 (85%) were included in the meta-analysis. Tailoring had no statistically significant effect on dropout attrition at 1-month (risk ratio [RR]=1.02, 95% CI 0.95-1.09; P=.58; I2=78%), 3-month (RR=0.99, 95% CI 0.95-1.04; P=.80; I2=73%), 6-month (RR=1.00, 95% CI 0.95-1.05; P=.90; I2=43%), or 12-month (RR=0.97, 95% CI 0.92-1.02; P=.26; I2=28%) follow-ups. Subgroup analyses suggested that there was a statistically significant effect of tailoring between the active and passive subgroups at 1-month (P=.03), 3-month (P<.001), and 6-month (P=.02) follow-ups but not at 12-month follow-up (P=.25). Conclusions The results suggest that tailoring of web-based smoking cessation interventions may not be associated with reduced rates of dropout attrition at 1-, 3-, 6-, or 12-month follow-ups. Significant differences between studies that include untailored active and passive control groups suggest that the role of tailoring may be more prominent when studies include a passive control group. These findings may be because of variability in the presence of additional features, the definition of smokers used, and the duration of smoking abstinence measured. Future studies should incorporate active web-based controls, compare the impact of different tailoring strategies, and include populations outside of the Western countries.

Although the literature on tipping is enormous, it is still unclear what motivates people to tip. In particular, it is unresolved how tips depend on service quality, patronage frequency, and group sizes, why people tip more for better service if they do, and why they tip at all when they can avoid it. This study aims to fill this gap. It uses survey data to explore what motivates Czech restaurant customers to tip. Reasons for tipping, factors constituting service quality, and reasons for tipping more for better service are explored by descriptive statistics. The impact of service quality, group size, and patronage frequency on tips is assessed by random effects estimator and simple policy capturing. The results show that Czech customers tip mostly because of gratitude, to follow the social norm, and to avoid feeling guilty when not tipping. Most Czechs do not tip to supplement waiters’ wages. Their tips are strongly influenced by service quality, which includes the whole experience of a dinner in a restaurant and not only the waiter’s performance. They reward a good service because it is fair, out of gratitude, and to motivate the waiters to provide good service in the future, but not because it is prescribed by social norms. On the other hand, there is little evidence that their tips depend on patronage frequency or group size.

Abstract Background: Virtual Reality (VR) has been widely used in health-related fields. The aim of this study was to assess the effectiveness of virtual reality-based physical and psychological exercise on depression.Methods: A total of 752 patients with stroke from 11 randomized controlled trial (RCT) studies were included in this meta-analysis and the studies derived from 6 electronic databases searched from database inception to August 2021. For continuous results, the standardized mean differences (SMDs) and 95% confidence intervals (CIs) were calculated to synthesize the effects.Results: The meta-analysis showed that compared with control group, VR-based interventions significantly decreased the depression scale score (SMD = −0.71, 95% CI: −1.32, −0.10) in the subjects. The results showed that the the patient age and total intervention time had a significant impact on the outcome of depression. The smaller the age and longer the intervention duration, the greater the impact on the outcome of depression.Conclusions: The current meta-analysis indicated the virtual reality-based physical and psychological exercise has a significant effect on depression in stroke patients compared to controls. The study showed an outstanding reduction in depression for aged under 60 participants and intervention longer than 8 weeks. At the same time, clinical studies of different ages and different intervention time also need further in-depth study.

BACKGROUND Obesity and lack of physical activity are major health risk factors for many life-threatening diseases, such as cardiovascular diseases, type 2 diabetes, and cancer. The use of mobile app interventions to promote weight loss and boost physical activity among children and adults is fascinating owing to the demand for cutting-edge and more efficient interventions. Previously published studies have examined different types of technology-based interventions and their impact on weight loss and increase in physical activity, but evidence regarding the impact of only a mobile phone app on weight loss and increase in physical activity is still lacking. OBJECTIVE The main objective of this study was to assess the efficacy of a mobile phone app intervention for reducing body weight and increasing physical activity among children and adults. METHODS PubMed, Google Scholar, Scopus, EMBASE, and the Web of Science electronic databases were searched for studies published between January 1, 2000, and April 30, 2019, without language restrictions. Two experts independently screened all the titles and abstracts to find the most appropriate studies. To be included, studies had to be either a randomized controlled trial or a case-control study that assessed a mobile phone app intervention with body weight loss and physical activity outcomes. The Cochrane Collaboration Risk of Bias tool was used to examine the risk of publication bias. RESULTS A total of 12 studies involving a mobile phone app intervention were included in this meta-analysis. Compared with the control group, the use of a mobile phone app was associated with significant changes in body weight (−1.07 kg, 95% CI −1.92 to −0.21, <i>P</i>=.01) and body mass index (−0.45 kg/m2, 95% CI −0.78 to −0.12, <i>P</i>=.008). Moreover, a nonsignificant increase in physical activity was observed (0.17, 95% CI −2.21 to 2.55, <i>P</i>=.88). CONCLUSIONS The findings of this study demonstrate the promising and emerging efficacy of using mobile phone app interventions for weight loss. Future studies are needed to explore the long-term efficacy of mobile app interventions in larger samples.
