Review
Optimism is a personality trait strongly associated with physical and psychological well-being, with correlates in nonhuman species. Optimistic individuals hold positive expectancies for their future, have better physical and psychological health, recover faster after heart disease and other ailments, and cope more effectively with stress and anxiety. We performed a systematic review of neuroimaging studies focusing on neural correlates of optimism. A search identified 14 papers eligible for inclusion. Two key brain areas were linked to optimism: the anterior cingulate cortex (ACC), involved in imagining the future and processing of self-referential information; and the inferior frontal gyrus (IFG), involved in response inhibition and processing relevant cues. ACC activity was positively correlated with trait optimism and with the probability estimations of future positive events. Behavioral measures of optimistic tendencies investigated through the belief update task correlated positively with IFG activity. Elucidating the neural underpinnings of optimism may inform both the development of prevention and treatment strategies for several mental disorders negatively associated with optimism, such as depression, as well as help to foster new resilience promotion interventions targeting healthy, vulnerable, and mentally ill individuals.

Review
BACKGROUND
Digital technologies facilitate everyday life, social connectedness, aging at home, well-being, and dignified care. However, older adults are disproportionately excluded from these benefits. Equal digital opportunities, access, and meaningful engagement require an understanding of older adults' experience across different stages of the technological engagement life cycle from nonuse and initial adoption to sustained use, factors influencing their decisions, and how the experience changes over time.
OBJECTIVE
Our objectives were to identify the extent and breadth of existing literature on older adults' perspective on digital engagement and summarize the barriers to and facilitators for technological nonuse, initial adoption, and sustained digital technology engagement.
METHODS
We used the Arksey and O'Malley framework for the scoping review process. We searched MEDLINE, PsycINFO, CINAHL, Web of Science, and ACM digital library for primary studies published between 2005 and 2021. The inclusion and exclusion criteria were developed based on the Joanna Briggs Institute (participants, content, and context) framework. Studies that investigated the digital engagement experience as well as barriers to and facilitators of older adults' digital technology engagement were included. The characteristics of the study, types of digital technology, and digital engagement levels were analyzed descriptively. Content analysis was used to generate tentative elements using a congruent theme, and barriers and facilitators were mapped over the capability, opportunity, and motivation behavior change model (COM-B) and the theoretical domain framework. The findings were reported in accordance with the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews).
RESULTS
In total, 96 publications were eligible for the final charting and synthesis. Most of the studies were published over the past 5 years, investigated the initial adoption stage of digital engagement, and focused on everyday technologies. The most cited barriers and facilitators across the engagement stages from each COM-B component were capability (eg, physical and psychological changes and lack of skill), opportunity (eg, technological features, environmental context, and resources), and motivation (eg, optimism from perceived usefulness and beliefs about capability).
CONCLUSIONS
The COM-B model and theoretical domain framework provide a guide for identifying multiple and intertwined barriers and facilitators at each stage of digital engagement. There are limited studies looking into the whole spectrum of older adults' digital technology experience; in particular, studies on technological nonuse and sustained use stages are rare. Future research and practice should focus on tailored interventions accounting for the barriers to older adults' digital engagement and addressing capabilities, motivation, and opportunities; affordable, usable, and useful digital technologies, which address the changes and capability requirements of older adults and are cocreated with a value framework; and lifelong learning and empowerment to develop older adults' knowledge and skills to cope with digital technology development.

Review
BACKGROUND
The impact of psychological factors on pain levels continues to be of interest throughout a cancer patient's journey. The relationship between pain and optimism has been described previously in patients with various diseases.
OBJECTIVES
We further investigated the effect of optimism on pain levels felt by patients diagnosed and living with cancer before and after surgery.
MATERIALS AND METHODS
The search strategy for relevant articles from inception through June 2020 included five databases. The main outcome of interest was the effect of optimism on cancer-related pain.
RESULTS
We identified 482 studies. After the full-text screening, seven articles meeting the inclusion criteria were included. Seven studies were analyzed and are included in the data table. Of the seven included articles, four articles described the association of optimism with cancer pain; four articles studied the relationship between optimism and chronic postsurgical pain (CPSP), and one article investigated optimism's relationship with acute postsurgical pain (APSP). All articles observed a negative correlation between optimism and pain levels.
CONCLUSION
Despite the differences in the pathophysiology of pain types investigated, and which stage of the patient's journey pain was experienced, all studies reported a negative association with the level of optimism and pain described by patients. Therefore, promoting and supporting psychological coping techniques, including optimism for cancer patients may decrease patients' suffering, increase their quality of life at different cancer stages, and reduce opioid use.

Meta-Analysis Review
Just as happy people see the proverbial glass as half-full, 'optimistic' or 'pessimistic' responses to ambiguity might also reflect affective states in animals. Judgement bias tests, designed to measure these responses, are an increasingly popular way of assessing animal affect and there is now a substantial, but heterogeneous, literature on their use across different species, affect manipulations, and study designs. By conducting a systematic review and meta-analysis of 459 effect sizes from 71 studies of non-pharmacological affect manipulations on 22 non-human species, we show that animals in relatively better conditions, assumed to generate more positive affect, show more 'optimistic' judgements of ambiguity than those in relatively worse conditions. Overall effects are small when considering responses to all cues, but become more pronounced when non-ambiguous training cues are excluded from analyses or when focusing only on the most divergent responses between treatment groups. Task type (go/no-go; go/go active choice), training cue reinforcement (reward-punishment; reward-null; reward-reward) and sex of animals emerge as potential moderators of effect sizes in judgement bias tests.

Meta-Analysis
AIM
Preterm birth(<37 gestational weeks) is associated with numerous adversities, however, data on positive developmental outcomes remain limited. We examined if preterm and term born(≥37 gestational weeks) adults differ in dispositional optimism/pessimism, a personality trait associated with health and wellbeing. We assessed if birth weight z-score, neurosensory impairments and parental education modified the outcome.
METHODS
We systematically searched PubMed and Web of Science for cohort or case-control studies(born ≥ 1970) with data on gestational age and optimism/pessimism reported using the Life-Orientation-Test-Revised in adulthood(≥18 years). The three identified studies(Helsinki Study of Very Low Birth Weight Adults; Arvo Ylppö Longitudinal Study; Avon Longitudinal Study of Parents and Children) provided data for the two-step random-effects linear regression Individual-Participant-Data meta-analysis.
RESULTS
Preterm and term borns did not differ on optimism(p = 0.76). Preterms scored higher on pessimism than term borns(Mean difference = 0.35, 95%Confidence Interval 0.36, 0.60, p = 0.007), although not after full adjustment. Preterm born participants, but not term born participants, with higher birth weight z-score, had higher optimism scores (0.30 raw score units per standard deviation increase, 95% CI 0.10, 0.49, p = 0.003); preterm vs term x birth weight z-score interaction p = 0.004).
CONCLUSIONS
Preterm and term born adults display similar optimism. In preterms, higher birth weight may foster developmental trajectories promoting more optimistic life orientations.

Review
All societies should carefully address the child abuse and neglect phenomenon due to its acute and chronic sequelae. Even if artificial intelligence (AI) implementation in this field could be helpful, the state of the art of this implementation is not known. No studies have comprehensively reviewed the types of AI models that have been developed/validated. Furthermore, no indications about the risk of bias in these studies are available. For these reasons, the authors conducted a systematic review of the PubMed database to answer the following questions: "what is the state of the art about the development and/or validation of AI predictive models useful to contrast child abuse and neglect phenomenon?"; "which is the risk of bias of the included articles?". The inclusion criteria were: articles written in English and dated from January 1985 to 31 March 2023; publications that used a medical and/or protective service dataset to develop and/or validate AI prediction models. The reviewers screened 413 articles. Among them, seven papers were included. Their analysis showed that: the types of input data were heterogeneous; artificial neural networks, convolutional neural networks, and natural language processing were used; the datasets had a median size of 2600 cases; the risk of bias was high for all studies. The results of the review pointed out that the implementation of AI in the child abuse and neglect field lagged compared to other medical fields. Furthermore, the evaluation of the risk of bias suggested that future studies should provide an appropriate choice of sample size, validation, and management of overfitting, optimism, and missing data.

OBJECTIVE
To ascertain the strength of association between dispositional optimism, assessed with the Revised Life Orientation Test (LOT-R), and obstetrical outcomes, and to evaluate women's social characteristics that may lead to low dispositional optimism during pregnancy.
STUDY DESIGN
The research was conducted using MEDLINE, EMBASE, Scopus, Web of Sciences, Cochrane Database, and ClinicalTrial.gov as electronic databases. The articles were identified with the use of a combination of the relevant heading term, key words, and word variants for: "optimism" or "happiness" and "pregnancy" or "obstetrical outcomes", from the inception of each database to June 2019. Review of articles also included the abstracts of all references retrieved from the search. Randomized, cohort, case-control, or case series were all accepted study designs. Only studies reporting obstetrical outcomes in women undergone LOT-R to assess dispositional optimism during pregnancy were included. Obstetrical outcomes included preterm birth, pre-eclampsia and small for gestational age fetuses. All analyses were carried out using the random effects model. Dichotomous variables were analyzed using the odds ratio (OR) with a 95 % confidence interval (95 % CI). No continuous variables were compared in the analysis. Significance level was set at P < 0.05. Heterogeneity was measured using I-squared (Higgins I).
RESULTS
Two prospective cohort studies, including 3,570 pregnancies undergone LOT-R - mostly during the second trimester - were included in the systematic review. Out of the 3,570 pregnancies included, 411 were in the lowest quartile of optimism, according to LOT-R score. Dispositional optimism showed a trend towards lower incidence of preterm birth (7.6 % vs 9.7 %; OR 0.76, CI 0.53-1.09); no difference between women at higher levels and women in the lowest quartile of optimism was found in preeclampsia and small for gestational age. Women at higher levels of dispositional optimism were significantly associated with: age ≥ 30 years; marriage or "marriage-like status"; lower rates of public assistance and smoking; white ethnicity; higher rates of higher education.
CONCLUSION
There are limited data on optimism and obstetric outcomes. Higher levels of optimism, evaluated by the LOT-R tool in two studies, are associated with a non-significant decrease in preterm birth.

Review
OBJECTIVE
To systematically synthesize research evidence on barriers and facilitators to pressure injury prevention in hospital settings.
METHODS
A systematic literature review of quantitative, qualitative, and mixed methods research was undertaken using PubMed, MEDLINE, Embase, CINAHL, and Cochrane Library. Studies that reported barriers or/and facilitators to pressure injury prevention in the acute care settings and published in English from 2008 to 2022 were included. Studies were excluded if they were conducted in residential care facilities and nursing homes, or other long-term community care settings. Two authors independently screened articles against the inclusion and exclusion criteria. Quality appraisal was conducted by two authors by using the Mixed Methods Appraisal Tool. Reported results were mapped to the Theoretical Domains Framework to identify the barriers and facilitators to pressure injury prevention.
RESULTS
A total of 78 studies were included. There were 65 quantitative studies, 11 qualitative studies, and two mix-methods studies. The most salient Theoretical Domains Framework domains identified in this review were "Knowledge", "Skills", "Environmental Context and Resources", "Optimism", "Social/Professional Role and Identity", and "Social influences".
CONCLUSION
The barriers and facilitators to pressure injury prevention in hospital settings identified in this systematic review were diverse, and included issues at both individual and organizational level. Healthcare organizations can address the barriers and facilitators from the influential Theoretical Domains Framework domains. Future research is required to investigate the effectiveness of behaviour change interventions that specifically target these barriers and facilitators to pressure injury prevention.

Meta-Analysis
BACKGROUND
The effect of psychological health on cardiovascular disease is an underappreciated yet important area of study. Understanding the relationship between these two entities may allow for more comprehensive care of those with cardiovascular disease. The primary objective of this meta-analysis is to evaluate the relationship between optimism and risk of developing adverse events such as all-cause mortality or fatal and non-fatal cardiovascular disease in community-based populations.
METHOD
A systematic search of electronic databases was conducted from inception through November 2021 for prospective studies evaluating optimism and adverse outcomes. Two reviewers independently selected prospective cohort studies that evaluated optimism and either all-cause mortality or cardiovascular disease and reported hazard ratios of these outcomes between optimistic and non-optimistic groups. Studies that reported odds ratio or other risk assessments were excluded. Pooled hazard ratios were calculated in random-effects meta-analyses.
RESULTS
Pooled analysis of six studies (n = 181,709) showed a pooled hazard ratio of 0.87 (95% confidence interval [CI], 0.82-0.92) for all-cause mortality among those with more optimistic mindset. Analysis of seven studies (n = 201,210) showed a pooled hazard ratio of 0.59 (95% CI, 0.37-0.93) for cardiovascular disease and pooled hazard ratio of 0.57 (95% CI, 0.07-4.56) for stroke.
CONCLUSIONS
In this pooled meta-analysis, optimism was associated with a reduced risk of all-cause mortality and of cardiovascular disease. These results suggest an important relationship between psychological health and cardiovascular disease that may serve as an area for intervention by clinicians.

Review
The objective of this study was to perform a meta-analysis of publications that reported the association between dispositional optimism and depression during youth, analyzing if the strength of this relationship varied according to potential factors. Systematic searches were carried out in APA PsycNet, Virtual Health Library, Embase, Web of Science, PubMed Central, and Scopus to collect English, Portuguese, or Spanish studies from 2009 onwards. Two reviewers selected the eligible articles, assessed the quality of each study, and extracted the data. For the synthesis of the results, a meta-analytic approach was used. We identified 4077 publications in the initial searches and 22 in the supplementary searches, from which 31 studies remained for analysis once the eligibility criteria were applied. The results showed a statistically significant negative association between dispositional optimism and depression in the young population, age being a factor that modifies the effect measure between these variables. This meta-analysis provides a consistent and robust synthesis on the interaction effect between dispositional optimism and depression in the young population. Based on these findings, early clinical admissions may effectively improve optimistic tendencies in young people, which could help them prevent depressive symptoms or episodes.
