ABSTRACT
The influence of genetic variants related to opioid use disorder (OUD) was evaluated using multiple logistic regression analysis in self-reported assigned African American/Afro-Caribbean and European biogeographical ancestry groups (BGAGs) and by sex. From a sample size of 1301 adult patients (>18 years of age) seen in emergency departments of three medical centers in Ohio, six variants were found to be associated with OUD. Two of the variants, rs2740574 (CYP3A4) and rs324029 (DRD3), were included in the analysis having met criteria of at least five subjects for each BGAG, variant carrier status, and OUD status combinations. Variant carriers in the African/Afro-Caribbean BGAG had slightly lower predicted probabilities of OUD. Variant carriers in the European BGAG had slightly higher predicted probabilities of OUD. Relative to sex, all the six variants met evaluation criteria (five subjects for all sex, variant, and OUD status combinations). No statistically significant interactions were found between a given variant, BGAGs and sex. Findings suggest variant testing relative to OUD risk can be applied across BGAGs and sex, however, studies in larger populations are needed.

In addition to current challenges in food production arising from climate change, soil salinization, drought, flooding, and human-caused disruption, abrupt sunlight reduction scenarios (ASRS), e.g., a nuclear winter, supervolcano eruption, or large asteroid or comet strike, are catastrophes that would severely disrupt the global food supply and decimate normal agricultural practices. In such global catastrophes, teragrams of particulate matter, such as aerosols of soot, dust, and sulfates, would be injected into the stratosphere and block sunlight for multiple years. The reduction of incident sunlight would cause a decrease in temperature and precipitation and major shifts to climate patterns leading to devastating reductions in agricultural production of traditional food crops. To survive a catastrophic ASRS or endure current and future disasters and famines, humans might need to rely on post-catastrophic foods, or those that could be foraged, grown, or produced under the new climate conditions to supplement reduced availability of traditional foods. These foods have sometimes been referred to as emergency, alternate, or resilient foods in the literature. While there is a growing body of work that summarizes potential post-catastrophic foods and their nutritional profiles based on existing data in the literature, this article documents a list of protocols to experimentally determine fundamental nutritional properties of post-catastrophic foods that can be used to assess the relative contributions of those foods to a balanced human diet that meets established nutritional requirements while avoiding toxic levels of nutrients. © 2024 The Author(s).

Although clinical psychologists have long speculated that antagonistic individuals may lack insight into their moral deficits, some evidence has shown that more (vs. less) antagonistic people view moral traits as somewhat desirable and rate themselves as lower on moral characteristics (suggestive of some insight). But, we suggest that antagonistic people's struggles with insight can be detected as part of a basic social-cognitive bias that entails believing the self is better-than-average on socially desirable characteristics (i.e., the "better-than-average effect" [BTAE]). Specifically, although antagonistic people may rate themselves lower on moral characteristics than less antagonistic people, they may still believe that their relative standing on moral characteristics compares favorably to others. Participants (N = 515) completed indicators of the Dark Tetrad (D4) constructs (narcissism, Machiavellianism, psychopathy, and sadism) and rated themselves in relation to others on moral and immoral character traits. Overall, participants exhibited very large BTAEs (i.e., rated the self as "better-than-average" on moral character traits); only psychopathy and sadism consistently related negatively to BTAEs, but people with elevations in each D4 construct (or any D4 facet) still exhibited large-to-very-large BTAEs. Such antagonistic participants viewed themselves as possessing substantially greater amounts of moral than immoral character traits but viewed average others as possessing an equal mix of these traits.

ABSTRACT
SCOPE: A study is conducted to determine the anti-inflammatory effects of cocoa and polyphenol-rich cocoa fractions in the dextran sulfate sodium (DSS)-induced mouse model of acute colonic inflammation. METHODS AND RESULTS: Male C57BL/6J mice are treated with dietary cocoa powder, an extractable cocoa polyphenol fraction, or a non-extractable cocoa polyphenol fraction for 2 weeks prior to treatment with 2.5% DSS in the drinking water for 7 days to induce colonic inflammation. Cocoa treatment continues during the DSS period. Cocoa and/or cocoa fractions exacerbate DSS-induced weight loss and fail to mitigate DSS-induced colon shortening but do improve splenomegaly. Cocoa/cocoa fraction treatment fails to mitigate DSS-induced mRNA and protein markers of inflammation. Principal component analysis shows overlap between cocoa or cocoa fraction-treated mice and DSS-induced controls, but separation from mice not treated with DSS. CONCLUSION: The results suggest cocoa and cocoa polyphenols may not be useful in mitigating acute colonic inflammation.

Numerous studies show that perceived authenticity is a reliable predictor of mental health outcomes. To expand on these studies, we examined whether such relations could be due to perceived authenticity's confounding with both self-esteem and executive functioning. A representative sample of US participants (N = 446; Mage = 46.10; 51.1% female; 78.0% White) completed measures of perceived authenticity, self-esteem, executive functioning, and various indicators of mental health (e.g., subjective wellbeing, depression). At the bivariate level, perceived authenticity had a positive, large correlation with a mental health composite. However, after controlling for self-esteem and executive functioning, this relationship became nonsignificant and trivial in size. The findings extend basic understanding of how self-relevant constructs contribute to mental health and suggest advice for individuals looking to capitalize on evidence linking perceived authenticity to mental health benefits: Build a strong base of self-worth and exercise agency.
ABSTRACT
Endorsement of the moral foundations specified by Moral Foundations Theory (MFT) can sometimes fail to relate negatively to certain dispositions indicative of bad moral character. This evidence has fueled some concerns over whether the moral foundations in MFT are "moral." To increase understanding of how moral foundations relate to moral character, we proposed the "asymmetry hypothesis." This hypothesis states that "good" character is a more powerful predictor of each moral foundation than "bad" character. Put differently, there is an asymmetry in the strength (not merely direction) with which the moral foundations relate to encompassing indicators of good versus bad character. This is important because it suggests that links between the moral foundations and moral character will be somewhat concealed by focusing on bad character and/or not considering encompassing indicators of good character. A sample of college participants (N = 514) rated their endorsement of moral foundations and completed two sets of measures that represented encompassing indicators of both good and bad character. The data supported the asymmetry hypothesis: Each encompassing good-character assessment was a stronger predictor of each moral foundation than its corresponding encompassing bad-character assessment. Furthermore, variance unique to any good-character assessment had about moderate relations with each moral foundation, but variance unique to any bad-character assessment had no more than small relations with each moral foundation. The study provides a more nuanced understanding of how moral character relates to moral foundations and highlights utility in considering moral character as multidimensional.
ABSTRACT
OBJECTIVE: The US has the highest incarceration rate in the world; incarceration's direct and indirect toll on the health and health care use of youth is rarely investigated. We sought to compare the health of youth with known personal or family justice involvement and a matched cohort of youth without known personal/family justice involvement. METHODS: A cross-sectional matched parallel cohort study was conducted. We queried electronic health records on youth (<21 years) with a visit in a large Midwestern pediatric hospital-based institution from January 2009 to December 2020. Youth were located by searching for justice-related (eg, prison, jail) keywords within all clinician notes. Health diagnostic profiles were measured using ICD 9/10 codes. Health care use included total admissions, inpatient days, emergent and urgent visits, and outpatient visits. RESULTS: Across all youth at one institution over an 11-year period, 2.2% (N = 38,263) were identified as having probable personal or family justice-involvement. Youth with personal or familial justice involvement had 1.5-16.2 times the prevalence of mental health and physical health diagnoses across all domain groupings compared to a matched sample and the total population sample. From 2009-2020, approximately two-thirds of behavioral health care and nearly a quarter of all hospital inpatient days were attributed to the 2.2% of youth with probable personal or familial justice system involvement. CONCLUSION: The study illuminates the vast disparities between youth with indirect or direct contact with the criminal legal system and matched youth with no documented contact. Better investment in monitoring and prevention efforts are needed.
ABSTRACT
In the event of a sunlight-blocking, temperature-lowering global catastrophe, such as a global nuclear war, super-volcano eruption or large asteroid strike, normal agricultural practices would be severely disrupted with a devastating impact on the global food supply. Despite the improbability of such an occurrence, it is prudent to consider how to sustain the surviving population following a global catastrophe until normal weather and climate patterns resume. Additionally, the ongoing challenges posed by climate change, droughts, flooding, soil salinization, and famine highlight the importance of developing food systems with resilient inputs such as lignocellulosic biomass. With its high proportion of cellulose, the abundant lignocellulosic biomass found across the Earth's land surfaces could be a source of energy and nutrition, but it would first need to be converted into foods. To understand the potential of lignocellulosic biomass to provide energy and nutrition to humans in post-catastrophic and other food crisis scenarios, compositional analyses should be completed to gauge the amount of energy (soluble sugars) and other macronutrients (protein and lipids) that might be available and the level of difficulty in extracting them. Suitable preparation of the lignocellulosic biomass is critical to achieve consistent and comparable results from these analyses. Here we describe a compilation of protocols to prepare lignocellulosic biomass and analyze its composition to understand its potential as a precursor to produce post-catastrophic foods which are those that could be foraged, grown, or produced under the new climate conditions to supplement reduced availability of traditional foods. These foods have sometimes been referred to in the literature as emergency, alternate, or resilient foods. © 2024 The Authors. Current Protocols published by Wiley Periodicals LLC.

Big data refers to extremely large data generated at high volume, velocity, variety, and veracity. The nurse scientist is uniquely positioned to leverage big data to suggest novel hypotheses on patient care and the healthcare system. The purpose of this paper is to provide an introductory guide to understanding the use and capability of big data for nurse scientists. Herein, we discuss the practical, ethical, social, and educational implications of using big data in nursing research. Some practical challenges with the use of big data include data accessibility, data quality, missing data, variable data standards, fragmentation of health data, and software considerations. Opposing ethical positions arise with the use of big data, and arguments for and against the use of big data are underpinned by concerns about confidentiality, anonymity, and autonomy. The use of big data has health equity dimensions and addressing equity in data is an ethical imperative. There is a need to incorporate competencies needed to leverage big data for nursing research into advanced nursing educational curricula. Nursing science has a great opportunity to evolve and embrace the potential of big data. Nurse scientists should not be spectators but collaborators and drivers of policy change to better leverage and harness the potential of big data.

BACKGROUND: Despite the life-threatening nature of sepsis, little is known about the emotional experiences of patients and their families during sepsis events. We conducted a sentiment analysis pertaining to sepsis incidents involving patients and families, leveraging textual data retrieved from a publicly available blog post disseminated by the Centers for Disease Control and Prevention (CDC). OBJECTIVE: This investigation involved a sentiment analysis of patient- and family-related sepsis events, leveraging text responses sourced from a publicly accessible blog post disseminated by the CDC. Driven by the imperative to elucidate the emotional dynamics encountered by patients and their families throughout sepsis incidents, the overarching aims centered on elucidating the emotional ramifications of sepsis on both patients and their families and discerning potential avenues for enhancing the quality of sepsis care. METHODS: The research used a cross-sectional data mining methodology to investigate the sentiments and emotional aspects linked to sepsis, using a data set sourced from the CDC, which encompasses 170 responses from both patients and caregivers, spanning the period between September 2014 and September 2020. This investigation used the National Research Council Canada Emotion Lexicon for sentiment analysis, coupled with a combination of manual and automated techniques to extract salient features from textual responses. The study used negative binomial least absolute shrinkage and selection operator regressions to ascertain significant textual features that correlated with specific emotional states. Moreover, the visualization of Plutchik's Wheel of Emotions facilitated the discernment of prevailing emotions within the data set. RESULTS: The results showed that patients and their families experienced a range of emotions during sepsis events, including fear, anxiety, sadness, and gratitude. Our analyses revealed an estimated incidence rate ratio (IRR) of 1.35 for fear-related words and a 1.51 IRR for sadness-related words when mentioning "hospital" in sepsis-related experiences. Similarly, mentions of "intensive care unit" were associated with an average occurrence of 12.3 fear-related words and 10.8 sadness-related words. Surviving patients' experiences had an estimated 1.15 IRR for joy-related words, contrasting with discussions around organ failure, which were associated with multiple negative emotions including disgust, anger, fear, and sadness. Furthermore, mentions of "death" were linked to more fear and anger words but fewer joy-related words. Conversely, longer timelines in sepsis events were associated with more joy-related words and fewer fear-related words, potentially indicating improved emotional adaptation over time. CONCLUSIONS: The study's outcomes underscore the imperative for health care providers to integrate emotional support alongside medical interventions for patients and families affected by sepsis, emphasizing the emotional toll incurred and highlighting the necessity of acknowledgment and resolution, advocating for the use of sentiment analysis as a means to tailor personalized emotional aid, and thereby potentially augmenting both patient and family welfare and overall outcomes.
ABSTRACT
The "bad-begets-bad" phenomenon describes how witnessed or perceived misconduct in an organization promotes mental states and behavior that encourage further misconduct. Based in two perspectives on how the Dark Triad (DT) constructs (narcissism, Machiavellianism, psychopathy) differentiate, we proposed their roles in contributing to the bad-begets-bad phenomenon. A convenience sample of college students (N = 454) completed an online study in which they read vignettes depicting workplace misconduct wherein a reporting incentive was (incentive condition) or was not (no-incentive condition) offered. Subsequently, they reported their likelihood of possessing mental states (e.g., goals) and engaging in behavior broadly reflective of the bad-begets-bad phenomenon. Lastly, they completed the Short Dark Triad (SD3) questionnaire to assess narcissism, Machiavellianism, and psychopathy. We used a series of step-wise regression models to analyze the data. Consistent with the "malicious two" perspective on the DT, only Machiavellianism and psychopathy consistently predicted mental states and behavior reflective of the bad-begets-bad phenomenon. Also, consistent with the "cautious and adaptable Machiavellian perspective," only Machiavellianism interacted with the incentive condition to influence people's willingness to report misconduct (i.e., not further promote misconduct). Broadly, the data contribute to understanding the role of the DT in organizational settings and support two perspectives on how the DT should operate in the context of witnessing workplace misconduct.
ABSTRACT
Study objective: Earlier intervention for opioid use disorder (OUD) may reduce long-term health implications. Emergency departments (EDs) in the United States treat millions with OUD annually who may not seek care elsewhere. Our objectives were (1) to compare two screening measures for OUD characterization in the ED and (2) to determine the proportion of ED patients screening positive for OUD and those who endorse other substance use to guide future screening programs. Methods: A cross-sectional study of randomly selected adult patients presenting to three Midwestern US EDs were enrolled, with duplicate patients excluded. Surveys were administered via research assistant and documented on tablet devices. Demographics were self-reported, and OUD positivity was assessed by the DSM 5 checklist and the WHO ASSIST 3.1. The primary outcome was the concordance between two screening measures for OUD. Our secondary outcome was the proportion of ED patients meeting OUD criteria and endorsed co-occurring substance use disorder (SUD) criteria. Results: We enrolled 1305 participants; median age of participants was 46 years (range 18-84), with 639 (49.0%) Non-Hispanic, White, and 693 (53.1%) female. Current OUD positivity was identified in 17% (222 out of 1305) of the participants via either DSM-5 (two or more criteria) or ASSIST (score of 4 or greater). We found moderate agreement between the measures (kappa = 0.56; Phi coefficient = 0.57). Of individuals screening positive for OUD, 182 (82%) endorsed criteria for co-occurring SUD. Conclusions: OUD is remarkably prevalent in ED populations, with one in six ED patients screening positive. We found a high prevalence of persons identified with OUD and co-occurring SUD, with moderate agreement between measures. Developing and implementing clinically feasible OUD screening in the ED is essential to enable intervention.
ABSTRACT
Multilevel risk factors may increase the risk of experiencing intimate partner violence among women. The overall goal of this study was to provide a comprehensive view of factors that may be associated with three forms of intimate partner violence. The primary aim was to explore associations between understudied factors and women's experiences of physical and sexual violence and stalking by an intimate partner. Secondary analysis of existing health registry data was conducted. Our evidence-driven strategy was based on a multipronged analytical approach informed by existing literature and the social-ecological model. We created an evidence-based hierarchical list comprised of three tiers. Three separate multiple logistic regression analyses were performed. Several shared risk factors were retained across all three forms including low levels of formal education, past experiences of non- partner sexual violence, residential instability, presence of children, experiences of a traumatic event and panic attacks, status of receiving US government benefits, and barriers to healthcare access. Results contribute to future research on intimate partner violence prevention by providing preliminary evidence of emerging factors associated with experiencing three forms of intimate partner violence.

The green tea polyphenol, (-)-epigallocatechin-3-gallate (EGCG), has been studied for its potential positive health effects, but human and animal model studies have reported potential toxicity at high oral bolus doses. This study used liquid chromatography-mass spectrometry-based metabolomics to compare the urinary EGCG metabolite profile after administration of a single non-toxic (100 mg kg-1) or toxic (750 mg kg-1) oral bolus dose to male C57BL6/J mice to better understand how EGCG metabolism varies with dose. EGCG metabolites, including methyl, glucuronide, sulfate, and glucoside conjugates, were tentatively identified based on their mass to charge (m/z) ratio and fragment ion patterns. Partial least squares discriminant analysis (PLS-DA) results showed clear separation of the urine metabolite profiles between treatment groups. The most differentiating metabolites in the negative and positive ion modes were provisionally identified as di-glucuronidated EGCG quinone and di-glucuronidated EGCG, respectively. The presence of EGCG oxidation products at toxic dose is consistent with studies showing that EGCG toxicity is associated with oxidative stress. Relative amounts of methylated metabolites increased with dose to a lesser extent than glucuronide and sulfate metabolites, indicating that methylation is more prominent at low doses, whereas glucuronidation and sulfation may be more important at higher doses. One limitation of the current work is that the lack of commercially-available EGCG metabolite standards prevented absolute metabolite quantification and identification. Despite this limitation, these findings provide a basis for better understanding the dose-dependent changes in EGCG metabolism and advance studies on how these differences may contribute to the toxicity of high doses of EGCG.

Sociocultural norms against women can contribute to promoting intimate partner violence (IPV) and shape women's decision to disclose IPV. A cross-cultural analysis of the existing literature is needed to present an overview of the influences of sociocultural norms on women's decisions regarding the disclosure of IPV across different cultural contexts. The purpose of the review was to synthesize published quantitative, qualitative, and mixed methods (MMs) studies to identify known sociocultural norms across different cultures that may influence women's decision to disclose IPV. The Whittemore and Knafl framework, Rayyan software, and PRISMA flow diagram were used. Databases included APA PsycInfo, CINAHL, PubMed, SocINDEX, and Women's Studies International. The quality of studies was assessed by the MMs appraisal tool. A total of 15 research articles written in English and published in peer-reviewed journals were included. Main categories emerged: (1) stigma surrounding IPV disclosure, victimization, and divorce; (2) gender roles; (3) preserving family honor; and (4) Children's well-being and future. A one-size-fits-all approach is not adequate for women who are considering disclosing IPV. Findings underscore that regardless of residing in individualistic countries, those sociocultural norms related to traditional gender roles and gender inequality are still important barriers to the disclosure of IPV among women with collectivist roots.
ABSTRACT
INTRODUCTION: Workplace experiences may place Black nurses at higher risk for poor sleep and adverse health outcomes. This study aimed to identify poor sleep prevalence and associations of workplace discrimination and workplace social capital with sleep. METHODOLOGY: Descriptive statistics and multiple linear regression with exploratory analyses were conducted of cross sectional survey data from US Black nurses. RESULTS: On average, 63 respondents reported sleeping 6.15 h, 45 min less daily than 6.9 h reported nationally for nurses. Ninety-percent of respondents reported poor sleep quality. While no direct significance was found, respondents reporting sleep quality changes had lower workplace social capital and higher workplace discrimination. CONCLUSION: Black nurses may have higher prevalence of poor sleep than the larger nursing workforce. A potential relationship between decreased sleep quality and negative perceptions of the work environment may exist. Organizations should examine sleep and potential occupational health inequities among Black nurses when considering worker health.
ABSTRACT
Background and Purpose: Caring for someone with Lewy body disease (LBD) is difficult. This study describes the development and validity testing of the LBD Caregiver Activities Scale (LBD-CAS). Methods: Caregiver interviews informed the development of the LBD-CAS. Experts estimated the content validity of items (I-CVI) and provided feedback about the scale. Family caregivers evaluated items for face validity. Results: Expert I-CVI ratings yielded 49 items with scores of 0.83 or higher. Four items with I-CVI scores <.83 were retained due to conceptual significance. The overall scale CVI was 0.86. Items evaluated by caregivers for face validity showed excellent variability in responses, with no major ceiling or floor effects. Conclusions: LBD-CAS showed evidence of content and face validity for the assessment of activities performed by LBD caregivers. Further psychometric testing is recommended.

Rationale & Objective: Continuous kidney replacement therapy (CKRT) is the predominant form of acute kidney replacement therapy used for critically ill adult patients with acute kidney injury (AKI). Given the variability in CKRT practice, a contemporary understanding of its epidemiology is necessary to improve care delivery. Study Design: Multicenter, prospective living registry. Setting & Population: 1,106 critically ill adults with AKI requiring CKRT from December 2013 to January 2021 across 5 academic centers and 6 intensive care units. Patients with pre-existing kidney failure and those with coronavirus 2 infection were excluded. Exposure: CKRT for more than 24 hours. Outcomes: Hospital mortality, kidney recovery, and health care resource utilization. Analytical Approach: Data were collected according to preselected timepoints at intensive care unit admission and CKRT initiation and analyzed descriptively. Results: Patients' characteristics, contributors to AKI, and CKRT indications differed among centers. Mean (standard deviation) age was 59.3 (13.9) years, 39.7% of patients were women, and median [IQR] APACHE-II (acute physiologic assessment and chronic health evaluation) score was 30 [25-34]. Overall, 41.1% of patients survived to hospital discharge. Patients that died were older (mean age 61 vs. 56.8, P < 0.001), had greater comorbidity (median Charlson score 3 [1-4] vs. 2 [1-3], P < 0.001), and higher acuity of illness (median APACHE-II score 30 [25-35] vs. 29 [24-33], P = 0.003). The most common condition predisposing to AKI was sepsis (42.6%), and the most common CKRT indications were oliguria/anuria (56.2%) and fluid overload (53.9%). Standardized mortality ratios were similar among centers. Limitations: The generalizability of these results to CKRT practices in nonacademic centers or low-and middle-income countries is limited. Conclusions: In this registry, sepsis was the major contributor to AKI and fluid management was collectively the most common CKRT indication. Significant heterogeneity in patient- and CKRT-specific characteristics was found in current practice. These data highlight the need for establishing benchmarks of CKRT delivery, performance, and patient outcomes. Data from this registry could assist with the design of such studies.
ABSTRACT
Rationale and Objective: Serum magnesium levels have been inversely yet inconsistently associated with cardiovascular (CV) outcomes. In this study, we examined the association of serum magnesium levels with CV outcomes in the Systolic Blood Pressure Intervention Trial (SPRINT) participants. Study Design: Case-control post hoc analysis of SPRINT. Setting & Participants: A total of 2,040 SPRINT participants with available serum samples at baseline level were included in this study. Case participants (n = 510) who experienced a CV event during the SPRINT observation period (median follow-up of 3.2 years) and control participants (n = 1,530) without CV events were sampled in a 1:3 ratio for measurements of serum magnesium level at baseline and 2-year follow-up. Predictors: Baseline serum magnesium levels and 2-year percentage change in serum magnesium levels (ΔSMg). Outcome: SPRINT primary composite CV outcome. Analytical Approach: Multivariable conditional logistic regression analysis, accounting for matching factors, was used to evaluate the association of baseline and ΔSMg with CV outcomes. Individual matching of cases and controls was based on the SPRINT treatment arm allocation (standard vs intensive) and prevalence of chronic kidney disease (CKD). Results: The median serum magnesium level at baseline was similar among the case and control groups. In a fully adjusted model, each standard deviation (SD) (0.18 mg/dL) higher of the baseline serum magnesium level was independently associated with a lower risk for composite CV outcomes in all study participants (adjusted odds ratio 95% CI, 0.79 [0.70-0.89]). This association was similar when serum magnesium levels were analyzed in quartiles but dissipated in the standard (vs intensive) arm of SPRINT (0.88 [0.76-1.02] vs 0.65 [0.53-0.79], respectively; Pinteraction = 0.06). The presence or absence of CKD at baseline did not modify this association. ΔSMg was not independently associated with CV outcomes occurring after 2 years. Limitations: ΔSMg was small in magnitude, limiting effect size. Conclusions: Higher baseline serum magnesium levels were independently associated with reduced risk for CV outcomes in all study participants, but ΔSMg was not associated with CV outcomes.
ABSTRACT
Micronutrient deficiencies caused by malnutrition and hidden hunger are a growing concern worldwide, exacerbated by climate change, COVID-19, and conflicts. A potentially sustainable way to mitigate such challenges is the production of nutrient-dense crops through agronomic biofortification techniques. Among several potential target crops, microgreens are considered suitable for mineral biofortification because of their short growth cycle, high content of nutrients, and low level of anti-nutritional factors. A study was conducted to evaluate the potential of zinc (Zn) biofortification of pea and sunflower microgreens via seed nutri-priming, examining the effect of different Zn sources (Zn sulfate, Zn-EDTA, and Zn oxide nanoparticles) and concentrations (0, 25, 50, 100, and 200 ppm) on microgreen yield components; mineral content; phytochemical constituents such as total chlorophyll, carotenoids, flavonoids, anthocyanin, and total phenolic compounds; antioxidant activity; and antinutrient factors like phytic acid. Treatments were arranged in a completely randomized factorial block design with three replications. Seed soaked in a 200 ppm ZnSO4 solution resulted in higher Zn accumulation in both peas (126.1%) and sunflower microgreens (229.8%). However, an antagonistic effect on the accumulation of other micronutrients (Fe, Mn, and Cu) was seen only in pea microgreens. Even at high concentrations, seed soaking in Zn-EDTA did not effectively accumulate Zn in both microgreens' species. ZnO increased the chlorophyll, total phenols, and antioxidant activities compared to Zn-EDTA. Seed soaking in ZnSO4 and ZnO solutions at higher concentrations resulted in a lower phytic acid/Zn molar ratio, suggesting the higher bioaccessibility of the biofortified Zn in both pea and sunflower microgreens. These results suggest that seed nutrient priming is feasible for enriching pea and sunflower microgreens with Zn. The most effective Zn source was ZnSO4, followed by ZnO. The optimal concentration of Zn fertilizer solution should be selected based on fertilizer source, target species, and desired Zn-enrichment level.
