Meta-Analysis
Safety and Efficacy of Immune Checkpoint Inhibitors in Cancer Patients and Preexisting Autoimmune Disease: A Systematic Review and Meta-Analysis in Non-Small-Cell Lung Cancer.
BACKGROUND
Cancer patients with preexisting autoimmune diseases (AID) have been traditionally excluded from clinical trials of immune checkpoint inhibitors (ICI) due to concerns for toxicity. As indications for ICI expand, more data are needed on the safety and efficacy of ICI treatment in cancer patients with AID.
METHODS
We systematically searched for studies consisting of NSCLC, AID, ICI, treatment response, and adverse events. Outcomes of interest include incidence of autoimmune flare, irAE, response rate, and ICI discontinuation. Study data were pooled using random-effects meta-analysis.
RESULTS
Data were extracted from 24 cohort studies, consisting of 11,567 cancer patients (3774 NSCLC patients and 1157 with AID). Pooled analysis revealed an AID flare incidence of 36% (95% CI, 27%-46%) in all cancers and 23% (95% CI, 9%-40%) in NSCLC. Preexisting AID was associated with an increased risk of de novo irAE in all cancer patients (RR 1.38, 95% CI, 1.16-1.65) and NSCLC patients (RR 1.51, 95% CI, 1.12-2.03). There was no difference in de novo grade 3 to 4 irAE and tumor response between cancer patients with and without AID. However, in NSCLC patients, preexisting AID was associated with a 2-fold increased risk of de novo grade 3 to 4 irAE (RR 1.95, 95% CI, 1.01-3.75) but also better tumor response in achieving a complete or partial response (RR 1.56, 95% CI, 1.19-2.04).
CONCLUSIONS
NSCLC patients with AID are at a higher risk of grade 3 to 4 irAE but are more likely to achieve treatment response. Prospective studies focused on optimizing immunotherapeutic strategies are needed to improve outcomes for NSCLC patients with AID.

Review
Moral distress (MD) is well-documented within the nursing literature and occurs when constraints prevent a correct course of action from being implemented. The measured frequency of MD has increased among nurses over recent years, especially since the COVID-19 Pandemic. MD is less understood among nurse leaders than other populations of nurses. A qualitative systematic review was conducted with the aim to synthesize the experiences of MD among nurse leaders. This review involved a search of three databases (Medline, CINAHL, and APA PsychINFO) which resulted in the retrieval of 303 articles. PRISMA review criteria guided authors during the article review and selection process. Following the review, six articles were identified meeting review criteria and quality was assessed using the Critical Appraisal Skills Programme (CASP) Checklist for qualitative studies. No ethical review was required for this systematic review. The six studies included in this review originated from the United States, Brazil, Turkey, and Iran. Leadership roles ranged from unit-based leadership to executive leadership. Assigned quality scores based upon CASP criteria ranged from 6 to 9 (moderate to high quality). Three analytical themes emerged from the synthesis: (1) moral distress is consuming; (2) constrained by the system; and (3) adapt to overcome. The unique contributors of MD among nurse leaders include the leadership role itself and challenges navigating moral situations as they arise. The nurse leader perspective should be considered in the development of future MD interventions.

Review
Recent advances in methods to culture pluripotent stem cells to model human development have resulted in entities that increasingly have recapitulated advanced stages of early embryo development. These entities, referred to by numerous terms such as embryoids, are becoming more sophisticated and could resemble human embryos ever more closely as research progresses. This paper reports a systematic review of the ethical, legal, regulatory, and policy questions and concerns found in the literature concerning human embryoid research published from 2016 to 2022. We identified 56 papers that use 53 distinct names or terms to refer to embryoids and four broad categories of ethical, legal, regulatory, or policy considerations in the literature: research justifications/benefits, ethical significance or moral status, permissible use, and regulatory and oversight challenges. Analyzing the full range of issues is a critical step toward fostering more robust ethical, legal, and social implications research in this emerging area and toward developing appropriate oversight.

Meta-Analysis
Snakebites still constitute a significant public health problem in developing countries and are considered a neglected tropical condition by the WHO. Snake accidents are associated with substantial morbidity and mortality and may produce secondary complications, such as severe infections. The objective of this systematic review was to determine the prevalence of snakebite infections and characterize the bacteria isolated from these infections. A systematic literature review in five databases was carried out to assess the prevalence of snakebite infection. A meta-analysis was performed using a random-effects model to calculate the pooled prevalence and 95% CIs. Cochran's Q test and the I2 statistic were used to assess between-study heterogeneity. The pooled prevalence of infection due to snakebite was 27.0% (95% CI: 22.0-32.0%), with high heterogeneity among studies (I2 = 99.7%). The prevalence was higher in Asia (32%) than in the Americas (21%). Snakebite infections required surgical interventions in 68% (95% CI: 37.0-98.0%). The leading group of pathogens identified corresponded to Gram-negative bacteria (63%), particularly Morganella morganii (32%), but also, Gram-positive cocci (40%), especially Enterococcus spp. (23%) and Staphylococcus aureus (15%). However, multiple other pathogens, including anaerobes, were found. A high prevalence of snakebite-associated infection has been described, primarily due to M. morganii, with the corresponding implications for empirical therapy. Rational use of antimicrobials is recommended, and this should guide initial empirical treatment. Moreover, isolation and identification of the possible bacteria present in snakebite wounds is recommended in all cases to confirm or rule out associated infection.

Review
BACKGROUND
Moral distress (MD) and moral injury (MI) are related constructs describing the negative consequences of morally challenging stressors. Despite growing support for the clinical relevance of these constructs, ongoing challenges regarding measurement quality risk limiting research and clinical advances. This study summarizes the nature, quality, and utility of existing MD and MI scales, and provides recommendations for future use.
METHOD
We identified psychometric studies describing the development or validation of MD or MI scales and extracted information on methodological and psychometric qualities. Content analyses identified specific outcomes measured by each scale.
RESULTS
We reviewed 77 studies representing 42 unique scales. The quality of psychometric approaches varied greatly across studies, and most failed to examine convergent and divergent validity. Content analyses indicated most scales measure exposures to potential moral stressors and outcomes together, with relatively few measuring only exposures (n = 3) or outcomes (n = 7). Scales using the term MD typically assess general distress. Scales using the term MI typically assess several specific outcomes.
CONCLUSIONS
Results show how the terms MD and MI are applied in research. Several scales were identified as appropriate for research and clinical use. Recommendations for the application, development, and validation of MD and MI scales are provided.

Review
OBJECTIVES
The review aims to synthesize and consolidate the factors and situations in which student nurses experience moral distress during their clinical practice and its potential implications for patient care and outcomes.
DESIGN
A qualitative systematic review.
DATA SOURCES
The articles were sourced from PubMed, Embase, CINAHL, Scopus, PsycInfo, Web of Science, ERIC (ProQuest), and ProQuest Dissertations and Theses Global Database between their inception dates to December 2022. Reference lists of included studies were also screened for additional studies.
REVIEW METHODS
Published and unpublished primary studies of any qualitative research methods focused on student nurses' experiences of moral distress regardless of their education level were included in this review. Two reviewers independently screened titles and abstracts, assessed full-text articles for eligibility, extracted data, and appraised the quality of included studies. Sandelowski and Barroso's (2007) two-step meta-synthesis approach and Braun and Clarke's (2006) thematic analysis framework were used to analyze and interpret findings from included studies.
RESULTS
Seven studies met the inclusion criteria and were included in the review. The meta-synthesis revealed an overarching theme, "Moral Distress and its Intertwined Roots". This was supported by the four main themes: 1) Inadequacy and lack of autonomy, 2) Unprofessionalism of healthcare professionals, 3) Differing cultural views and values of patients and their relatives, and 4) Healthcare needs versus resource constraints.
CONCLUSION
This review highlights the experiences of student nurses in situations of moral distress, including feelings of inadequacy and powerlessness when faced with ethical challenges, and the negative impact of resource constraints, unprofessional behavior, and cultural differences. Collaborative efforts between healthcare professionals and student nurses are needed to promote shared decision-making, prioritize ethical training, and provide culturally sensitive care to address these challenges and ultimately improve patient care.

Meta-Analysis Review
A systematic review and meta-analysis of human population studies on the association between exposure to toxic environmental chemicals and left ventricular dysfunction (LVD).
BACKGROUND
Exposure to environmental chemicals has been associated with an elevated risk of heart failure (HF). However, the impact on early markers of HF, such as left ventricular dysfunction (LVD), remains limited.
OBJECTIVE
To establish a foundation of evidence regarding early HF markers and their association with environmental pollutants, a systematic review and meta-analysis was conducted.
METHODS
The search, conducted on October 13th, 2023, encompassed PubMed, Embase, and Web of Science without filters, focusing on observational studies reporting myocardial geometrical, structural, or functional alterations in individuals without a history of heart disease. This included the general adult population, workers, young people, and the elderly. The risk of bias was assessed using the ROBINS-I tool at both study and item levels.
RESULTS
The systematic review included 17 studies involving 43.358 individuals exposed to air pollution and 2038 exposed to heavy metals. Approximately 41% of the effect measures of associations reported significant abnormalities in myocardial structure or function. The metanalyses by pollutants categories indicated positive associations between LV systolic and diastolic abnormalities and exposure to PM2.5 [-0.069 (-0.104, -0.033); -0.044 (-0.062, -0.025)] and PM10 [-0.055 (-0.087, -0.022); -0.030 (-0.050, -0.010)] and NO2 [-0.042 (-0.071, -0.013); -0.021 (-0.037, -0.004)], as well as positive associations between lead exposure and LV systolic abnormalities [-0.033 (-0.051, -0.016)].
CONCLUSIONS
Existing evidence shows that specific early markers of HF may be associated with exposure to chemical pollutants. It is recommended to include such endpoints in new longitudinal and case-control studies to confirm further risk associations. These studies should consider co-exposures, account for vulnerable groups, and identify cardiotoxic compounds that may require regulation. When examining the link between myocardial abnormalities and environmental exposure, it is also advisable to explore the supportive use of Adverse Outcome Pathway (AOP) approaches to confirm a causal relationship.

Meta-Analysis
CONTEXT
Anticariogenic properties have been ascribed to polyphenolic compounds present in high concentrations in numerous fruits. Berries, in particular, have been reported as potentially having an inhibitory effect on the dental biofilm and subsequently on caries, but the evidence is unclear.
OBJECTIVE
The objective of this review was to explore the literature and summarize the evidence for berries having an inhibitory effect on the dental biofilm and an anticariogenic effect.
DATA SOURCES
Following Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines, the PubMed, Web of Science, and SCOPUS databases were scanned using predefined and accessible terms, with a search strategy based on a structured PICO question.
DATA EXTRACTION
After article selection, 23 studies met the inclusion criteria, most of them being in vitro studies. A risk assessment was performed, and data were extracted and presented in a table for qualitative analysis.
DATA ANALYSIS
Meta-analyses were conducted using standardized mean differences (SMDs) with a 95% confidence interval (CI) by Review manager 5.4.
RESULTS
Only 3 types of berries were found to have a reported anticaries effect: grape seed extract (GSE), cranberry, and sour cherry. Nine studies that fulfilled the eligibility criteria were subjected to quantitative analysis. Meta-analyses showed GSE was associated with enhanced remineralization of dental enamel (SMD = .96 95% CI [.45, 1.46], P < .0002) and of dentin (SMD = .65 95% CI [.13, 1.17], P = .01). Cranberry extracts positively influenced the cariogenic dental biofilm by decreasing the biofilm biomass (SMD = -2.23 95% CI [-4.40, -.05], P = .04), and biovolume (SMD = -2.86 95% CI [-4.34, -1.37], P = .0002), and increasing the biofilm pH (SMD = 7.9 95% CI [3.49, 12.31], P < .0004).
CONCLUSION
Within the limitations of this systematic review and metaanalysis, GSE and cranberries or their active compounds could represent an alternative for caries management. Further clinical trials are needed to verify this effect in a clinical setting.

Review
BACKGROUND
Mobile apps are fundamental tools in today's society for practical and social endeavors. However, these technologies are often not usable for older users. Given the increased use of mobile apps by this group of users and the impact that certain services may have on their quality of life, such as mobile health, personal finance, or online administrative procedures, a clear set of guidelines for mobile app designers is needed. Existing recommendations for older adults focus on investigations with certain groups of older adults or have not been extracted from experimental results.
OBJECTIVE
In this research work, we systematically reviewed the scientific literature that provided recommendations for the design of mobile apps based on usability testing with older adults and organized such recommendations into a meaningful set of design guidelines.
METHODS
We conducted a systematic literature review of journal and conference articles from 2010 to 2021. We included articles that carried out usability tests with populations aged >60 years and presented transferable guidelines on mobile software design, resulting in a final set of 40 articles. We then carried out a thematic analysis with 3 rounds of analysis to provide meaning to an otherwise diverse set of recommendations. At this stage, we discarded recommendations that were made by just 1 article, were based on a specific mobile app and were therefore nontransferrable, were based on other authors' literature (as opposed to recommendations based on the results of usability tests), or were not sufficiently argued. With the remaining recommendations, we identified commonalities, wrote a faithful statement for each guideline, used a common language for the entire set, and organized the guidelines into categories, thereby giving shape to an otherwise diverse set of recommendations.
RESULTS
Among the 27 resulting guidelines, the rules Simplify and Increase the size and distance between interactive controls were transversal and of the greatest significance. The rest of the guidelines were divided into 5 categories (Help & Training, Navigation, Visual Design, Cognitive Load, and Interaction) and consequent subcategories in Visual Design (Layout, Icons, and Appearance) and Interaction (Input and Output). The recommendations were structured, explained in detail, and illustrated with applied examples extracted from the selected studies, where appropriate. We discussed the design implications of applying these guidelines, contextualized with relevant studies. We also discussed the limitations of the approach followed, stressing the need for further experimentation to gain a better understanding of how older adults use mobile apps and how to better design such apps with these users in mind.
CONCLUSIONS
The compiled guidelines support the design of mobile apps that cater to the needs of older adults because they are based on the results of actual usability tests with users aged >60 years.

A growing number of organizations are prioritizing diversity, equity, and inclusion (DEI) and antiracism in the workplace, including investing resources in DEI or antiracism training. However, such trainings vary widely in curriculum, objectives, delivery, and evaluation, with little known about the efficacy of existing trainings. The aim of this systematic review is to evaluate training characteristics, measures, and results of peer-reviewed studies (published between 2000 and 2022) testing DEI or antiracism trainings. Studies were identified using Google Scholar, JSTOR, and a university library database. Key search terms included "diversity, equity, and inclusion training"; "antiracism training"; and "effect," "impact," "outcome," or "evaluation." The search yielded N = 15 DEI training studies and N = 8 antiracism training studies. The majority of studies (75% of antiracism training; 66.6% of DEI training) utilized a one-time training session. Content, objectives, measures, and impact varied widely across studies. Randomized designs were uncommon (13%), and over 70% of studies had majority female participants. Findings highlight several strategies to advance the field of DEI and antiracism training, such as shifting curriculum from targeting individual knowledge to supporting behavioral and organizational change, providing longitudinal training, standardizing outcomes of interest, and implementing rigorous evaluation methods.
