RESUMO
Pancreatic cancer is an aggressive disease with a 5 year survival rate of 13%. This poor survival is attributed, in part, to limited and ineffective treatments for patients with metastatic disease, highlighting a need to identify molecular drivers of pancreatic cancer to target for more effective treatment. CD200 is a glycoprotein that interacts with the receptor CD200R and elicits an immunosuppressive response. Overexpression of CD200 has been associated with differential outcomes, depending on the tumor type. In the context of pancreatic cancer, we have previously reported that CD200 is expressed in the pancreatic tumor microenvironment (TME), and that targeting CD200 in murine tumor models reduces tumor burden. We hypothesized that CD200 is overexpressed on tumor and stromal populations in the pancreatic TME and that circulating levels of soluble CD200 (sCD200) have prognostic value for overall survival. We discovered that CD200 was overexpressed on immune, stromal, and tumor populations in the pancreatic TME. Particularly, single-cell RNA-sequencing indicated that CD200 was upregulated on inflammatory cancer-associated fibroblasts. Cytometry by time of flight analysis of PBMCs indicated that CD200 was overexpressed on innate immune populations, including monocytes, dendritic cells, and monocytic myeloid-derived suppressor cells. High sCD200 levels in plasma correlated with significantly worse overall and progression-free survival. Additionally, sCD200 correlated with the ratio of circulating matrix metalloproteinase (MMP) 3: tissue inhibitor of metalloproteinase (TIMP) 3 and MMP11/TIMP3. This study highlights the importance of CD200 expression in pancreatic cancer and provides the rationale for designing novel therapeutic strategies that target this protein.

AIMS: A novel large surface area microparticle paclitaxel (LSAM-PTX) has unique properties of long retention in cystic spaces while maintaining high drug concentration. We prospectively evaluated the safety and response of EUS-guided fine needle injection (EUS-FNI) of LSAM-PTX to chemoablate branch duct (BD)-IPMNs. METHODS: Subjects diagnosed with BD-IPMNs exhibiting at least one worrisome criteria and considered non-surgical were enrolled in a multicenter clinical trial (NCT03188991) and subsequently included in an Expanded Access Protocol (EAP) where they received EUS-FNI of LSAM-PTX (15 mg/mL). RESULTS: Six BD-IPMNs measuring (mean ± SD) 3.18 ± 0.76 cm in diameter among 5 subjects (mean age: 66 years) were treated by EUS-FNI of LSAM-PTX. A mean of 4 doses of LSAM-PTX (mean dose/cyst: 73 ± 31 mg) were administered, and subjects were followed for up to 32 months. The mean volume reduction/cyst ranged from 42 to 89% (9.58 ± 5.1 ml to 2.2 ± 1.1 ml (p = 0.016)). The mean surface area reduction ranged from 31 to 83% (21.9 ± 8.7 cm2 to 5.7 ± 2.5 cm2 (p = 0.009)). Higher dosing-frequency of EUS-FNI of LSAM-PTX significantly correlated with a reduction in cyst volume (R2 = 0.87, p = 0.03) and surface area (R2 = 0.83, p = 0.04). Comparing pre- and post-ablation samples, molecular analysis of the cyst fluid revealed a loss of IPMN-associated mutations in 5 cases (83.3%), while reemergence was observed in 1 case and persistence in 1 case. Intracystic changes (fibrosis/calcification) were observed in 83.3% (n = 5). One subject developed mild acute pancreatitis (1 of 22 EUS-FNIs of LSAM-PTX). CONCLUSION: In this EAP, EUS-FNI of LSAM-PTX into BD-IPMNs was safe and resulted in volume and surface area reduction, morphological changes, and loss of pathogenic mutations.

During acute pancreatitis (AP), free fatty acids (FFAs) are liberated from circulating triglycerides (TG) and injured adipocytes by pancreatic lipase. Circulating FFAs have been suspected as a source of systemic lipotoxicity in AP. However, assessment of FFAs is difficult and time-consuming, and little is known about relative levels of FFAs between patients with different severities of AP and controls. This study's aims were to assess early circulating levels of FFAs, (both saturated and unsaturated) in patients with AP vs. controls, and associations between FFA levels and AP severity. Serum samples from patients with AP were collected at enrollment (day 1 of hospital stay); serum samples were also collected from controls. FFAs including palmitic, palmitoleic, stearic, oleic, and linoleic acid were extracted and quantitated using gas chromatography separation. Severity of AP was determined by Revised Atlanta Classification. Differences in FFA levels and percentages of total FFAs were assessed between patients with AP and controls and patients with AP of different severity grades. A total of 93 patients with AP (48 female, 52%) and 29 controls (20 female, 69%) were enrolled. Of the patients with AP, 74 had mild/moderate and 19 had severe AP. Serum levels of all FFAs except stearic acid were significantly higher in patients with AP compared with controls. A strong and independent association between elevated palmitoleic acid levels and severe AP was found. Serum unsaturated FFA levels, specifically palmitoleic acid, appear to correlate with severe AP. These findings have potential clinical implications for targeted AP therapies.NEW & NOTEWORTHY Drivers of the inflammatory response in acute pancreatitis remain incompletely understood. Unsaturated fatty acids, specifically palmitoleic, appear to have an association with more severe acute pancreatitis. This finding presents a new clinical understanding of fatty acid toxicity and highlights a potential future target for treatment in severe acute pancreatitis.

INTRODUCTION: Recent pilot trials in acute pancreatitis (AP) found that lactated ringers (LR) usage may result in decreased risk of moderately severe/severe AP compared with normal saline, but their small sample sizes limit statistical power. We investigated whether LR usage is associated with improved outcomes in AP in an international multicenter prospective study. METHODS: Patients directly admitted with the diagnosis of AP were prospectively enrolled at 22 international sites between 2015 and 2018. Demographics, fluid administration, and AP severity data were collected in a standardized prospective manner to examine the association between LR and AP severity outcomes. Mixed-effects logistic regression analysis was performed to determine the direction and magnitude of the relationship between the type of fluid administered during the first 24 hours and the development of moderately severe/severe AP. RESULTS: Data from 999 patients were analyzed (mean age 51 years, female 52%, moderately severe/severe AP 24%). Usage of LR during the first 24 hours was associated with reduced odds of moderately severe/severe AP (adjusted odds ratio 0.52; P = 0.014) compared with normal saline after adjusting for region of enrollment, etiology, body mass index, and fluid volume and accounting for the variation across centers. Similar results were observed in sensitivity analyses eliminating the effects of admission organ failure, etiology, and excessive total fluid volume. DISCUSSION: LR administration in the first 24 hours of hospitalization was associated with improved AP severity. A large-scale randomized clinical trial is needed to confirm these findings.

Diabetes mellitus following an episode of acute pancreatitis (AP) is an increasingly discussed complication, but there are sparse prospective data on the incidence and risk factors. We evaluated data from a prospective, multicenter observational cohort study that enrolled adults hospitalized with AP between 2017 and 2021 and followed them for one year. Ninety-eight participants who completed 12-month follow-up were included in this analysis. Diabetes status was assessed using a combination of measured glycated hemoglobin (HbA1c) at predetermined time intervals or physician diagnosis. In 68 participants without diabetes at enrollment, the cumulative incidence of new-onset diabetes was 4.4 % (n = 3) at 3 months and 10.3 % (n = 7) at 12 months. No differences were observed in demographic or pancreatitis-related characteristics between those who did versus did not develop diabetes, in part due to small sample size. In summary, new-onset diabetes was identified in approximately 10 % within one year after an episode of AP. Larger prospective studies are needed to further define the incidence, risk factors, and mechanisms of diabetes and pre-diabetes following AP. NCT03063398.

BACKGROUND AND AIMS: Data on how to teach endosonographers needle-based confocal laser endomicroscopy (nCLE)-guided histologic diagnosis of pancreatic cystic lesions (PCLs) are limited. Hence, we developed and tested a structured educational program to train early-career endosonographers in nCLE-guided diagnosis of PCLs. METHODS: Twenty-one early-career nCLE-naïve endosonographers watched a teaching module outlining nCLE criteria for diagnosing PCLs. Participants then reviewed 80 high-yield nCLE videos, recorded diagnoses, and received expert feedback (phase 1). Observers were then randomized to a refresher feedback session or self-learning at 4 weeks. Eight weeks after training, participants independently assessed the same 80 nCLE videos without feedback and provided histologic predictions (phase 2). Diagnostic performance of nCLE to differentiate mucinous versus nonmucinous PCLs and to diagnose specific subtypes were analyzed using histopathology as the criterion standard. Learning curves were determined using cumulative sum analysis. RESULTS: Accuracy and diagnostic confidence for differentiating mucinous versus nonmucinous PCLs improved as endosonographers progressed through nCLE videos in phase 1 (P < .001). Similar trends were observed with the diagnosis of PCL subtypes. Most participants achieved competency interpreting nCLE, requiring a median of 38 assessments (range, 9-67). During phase 2, participants independently differentiated PCLs with high accuracy (89%), high confidence (83%), and substantial interobserver agreement (κ = .63). Accuracy for nCLE-guided PCL subtype diagnoses ranged from 82% to 96%. The learned nCLE skills did not deteriorate at 8 weeks and were not impacted by a refresher session. CONCLUSIONS: We developed a practical, effective, and durable educational intervention to train early-career endosonographers in nCLE-guided diagnosis of PCLs.

We sought to examine current practices and changes in practice regarding initial counseling for families of patients with hypoplastic left heart syndrome (HLHS) given the evolution of options and outcomes over time. Counseling (Norwood with Blalock-Taussig-Thomas shunt (NW-BTT), NW with right ventricle to pulmonary artery conduit (NW-RVPA), hybrid palliation, heart transplantation, or non-intervention/hospice (NI)) for patients with HLHS were queried via questionnaire of pediatric care professionals in 2021 and compared to identical questionnaire from 2011. Of 322 respondents in 2021 (39% female), 299 respondents were cardiologists (92.9%), 17cardiothoracic surgeons (5.3%), and 6 were nurse practitioners (1.9%). Respondents were largely from North America (96.9%). In 2021, NW-RVPA procedure was the preferred palliation for standard risk HLHS patient (61%) and was preferred across all US regions (p < 0.001). NI was offered as an option by 71.4% of respondents for standard risk patients and was the predominant strategy for patients with end-organ dysfunction, chromosomal abnormality, and prematurity (52%, 44%, and 45%, respectively). The hybrid procedure was preferred for low birth-weight infants (51%). In comparison to the identical 2011 questionnaire (n = 200), the NW-RVPA was endorsed more in 2021 (61% vs 52%, p = 0.04). For low birth-weight infants, hybrid procedure was more recommended than in 2011 (51% vs 21%, p < 0.001). The NW-RVPA operation is the most recommended strategy throughout the US for infants with HLHS. The hybrid procedure for low birth-weight infants is increasingly recommended. NI continues to be offered even in standard risk patients with HLHS.

There are currently no national data regarding U.S. Primary Care Physicians' (PCPs') suicide screening practices. This study surveyed 302 U.S. PCPs about their current suicide screening practices to identify service gaps and intervention points for social workers. Although one-third of PCPs reported providing screening and safety planning, few were using evidence-based tools. Factors that increased the likelihood of routine screening were belief in the importance of screening (p < .01), time (p < .01), and access to co-located behavioral health (p < .01). Findings support the role of social workers in primary care and suggest areas for training and collaboration.

OBJECTIVE: The purpose of this study was to evaluate the feasibility and impact of a suicide risk screening program in a rural West Virginia primary care practice. METHODS: Patients presenting for routine and sick visits were asked to participate in electronic suicide risk screening using the Ask Suicide-Screening Questions tool; screen positive individuals were assessed with the Ask Suicide-Screening Questions Brief Suicide Safety Assessment. Screening program feasibility was evaluated by the proportion of patients consenting to participate, participant Ask Suicide-Screening Questions and Brief Suicide Safety Assessment completion rates, and response to a question asking whether primary care providers should ask about suicide. Screening impact was evaluated quasi-experimentally by comparing electronic medical record documentation of suicide risk screening, assessment, and risk determination in practice patients before and after implementing the screening program. RESULTS: Over half of the patients approached agreed to participate in a research study about suicide (N = 196; 57.7%). Feasibility of the screening program was demonstrated by the high completion rates for the Ask Suicide-Screening Questions (99.0%) and the Brief Suicide Safety Assessment (100.0%) among study participants. Additionally, 95.4% (N = 187) of participants agreed primary care providers should screen patients for suicide. Suicide screening rates rose significantly between the baseline and intervention phases (5.8% to 61.0%; X2 = 200.61, P < 0.001), as did suicide risk detection rates (0.7% to 6.2%; X2 = 12.58, P < 0.001). CONCLUSION: Suicide risk screening was feasible and well accepted by adult patients in rural primary care and has potential to improve suicide risk detection in this setting.

OBJECTIVE: The aims of this study are to describe and evaluate the factors associated with missed nursing care in an acute care community hospital. BACKGROUND: Despite RNs' accountability for high-quality patient care in hospitals, missed nursing care is widespread, jeopardizing patient safety and health system costs. Better understanding of the factors associated with missed nursing care may provide nurse leaders with opportunities for improvement. METHODS: Using a cross-sectional correlational study design, 138 RNs were randomly sampled during May-June 2017. RESULTS: The extent of missed nursing care is consistent with other studies, was greater on medical-surgical and telemetry units compared with specialty units, and was negatively associated with staffing/resources, satisfaction with current position, and collegial nurse-physician relationships. CONCLUSION: Findings suggest urgent nurse leader action and future research.

BACKGROUND: The Precision Medicine Initiative will accelerate genomic discoveries that improve health care, necessitating a genomic competent workforce. PURPOSE: This study assessed leadership team (administrator/educator) year-long interventions to improve registered nurses' (RNs) capacity to integrate genomics into practice. METHODS: We examined genomic competency outcomes in 8,150 RNs. FINDINGS: Awareness and intention to learn more increased compared with controls. Findings suggest achieving genomic competency requires a longer intervention and support strategies such as infrastructure and policies. Leadership played a role in mobilizing staff, resources, and supporting infrastructure to sustain a large-scale competency effort on an institutional basis. DISCUSSION: Results demonstrate genomic workforce competency can be attained with leadership support and sufficient time. Our study provides evidence of the critical role health-care leaders play in facilitating genomic integration into health care to improve patient outcomes. Genomics' impact on quality, safety, and cost indicate a leader-initiated national competency effort is achievable and warranted.

OBJECTIVE: The aim of this study was to compare baseline and year 1 findings from a research-focused academic-service partnership (ASP) designed to increase research capacity, evidence-based practice (EBP) use, and research productivity. BACKGROUND: Few combined individual and organizational best practices could be found that successfully sustain EBP. An ASP model, using structural and enabling processes, was evaluated. METHODS: Using a nonexperimental pretest-posttest design, 67 acute care nurses who participated at baseline were resurveyed, and year 1 focus groups were conducted. RESULTS: Knowledge increased from baseline to year 1, and nurses who participated on a committee with an embedded scientist were more knowledgeable at year 1 than those who did not. While EBP confidence and self-reported EBP use did not improve, research productivity increased 33%. Year 1 focus groups identified facilitators and barriers. CONCLUSION: Findings support some EBP benefits related to a research-focused ASP including research productivity; however, implementation barriers and contextual factors may have limited potential outcomes.

BACKGROUND: Patients with end-stage renal disease have high mortality and symptom burden. Past studies demonstrated that nephrologists do not feel prepared to care for their patients at the end of life. We sought to characterize current palliative and end-of-life care education received during nephrology fellowship and compare this with data from 2003. STUDY DESIGN: Cross-sectional online survey of second-year nephrology trainees. Responses were compared to a similar survey in 2003. SETTING & PARTICIPANTS: 104 US nephrology fellowship programs in 2013. MEASUREMENTS: Quality of training in and attitudes toward end-of-life care and knowledge and preparedness to provide nephrology-specific end-of-life care. RESULTS: Of 204 fellows included for analysis (response rate, 65%), significantly more thought it was moderately to very important to learn to provide care at end of life in 2013 compared to 2003 (95% vs 54%; P<0.001). Nearly all (99%) fellows in both surveys believed physicians have a responsibility to help patients at end of life. Ranking of teaching quality during fellowship in all areas (mean, 4.1±0.8 on a scale of 0-5 [0, poor; 5, excellent]) and specific to end-of-life care (mean, 2.4±1.1) was unchanged from 2003, but knowledge of the annual gross mortality rate for dialysis patients was nominally worse in 2013 because only 57% versus 67% in 2003 answered correctly (P=0.05). To an open-ended question asking what would most improve fellows' end-of-life care education, the most common response was a required palliative medicine rotation during fellowship. LIMITATIONS: Assessments were based on fellows' subjective perceptions. CONCLUSIONS: Nephrology fellows increasingly believe they should learn to provide end-of-life care during fellowship. However, perceptions about the quality of this teaching have not improved during the past decade. Palliative care training should be integrated into nephrology fellowship curricula.

PURPOSE: Genomics is increasingly relevant to health care, necessitating support for nurses to incorporate genomic competencies into practice. The primary aim of this project was to develop, implement, and evaluate a year-long genomic education intervention that trained, supported, and supervised institutional administrator and educator champion dyads to increase nursing capacity to integrate genomics through assessments of program satisfaction and institutional achieved outcomes. DESIGN: Longitudinal study of 23 Magnet Recognition Program® Hospitals (21 intervention, 2 controls) participating in a 1-year new competency integration effort aimed at increasing genomic nursing competency and overcoming barriers to genomics integration in practice. METHODS: Champion dyads underwent genomic training consisting of one in-person kick-off training meeting followed by monthly education webinars. Champion dyads designed institution-specific action plans detailing objectives, methods or strategies used to engage and educate nursing staff, timeline for implementation, and outcomes achieved. Action plans focused on a minimum of seven genomic priority areas: champion dyad personal development; practice assessment; policy content assessment; staff knowledge needs assessment; staff development; plans for integration; and anticipated obstacles and challenges. Action plans were updated quarterly, outlining progress made as well as inclusion of new methods or strategies. Progress was validated through virtual site visits with the champion dyads and chief nursing officers. Descriptive data were collected on all strategies or methods utilized, and timeline for achievement. Descriptive data were analyzed using content analysis. FINDINGS: The complexity of the competency content and the uniqueness of social systems and infrastructure resulted in a significant variation of champion dyad interventions. CONCLUSIONS: Nursing champions can facilitate change in genomic nursing capacity through varied strategies but require substantial training in order to design and implement interventions. CLINICAL RELEVANCE: Genomics is critical to the practice of all nurses. There is a great opportunity and interest to address genomic knowledge deficits in the practicing nurse workforce as a strategy to improve patient outcomes. Exemplars of champion dyad interventions designed to increase nursing capacity focus on improving education, policy, and healthcare services.

OBJECTIVE: The aim of this study is to report baseline findings from a research-focused academic-service partnership. BACKGROUND: Despite widespread efforts, the research-practice gap remains considerable. A research-focused academic-service partnership may offer a strategy for decreasing this gap. METHODS: With the use of a shared model and a descriptive correlational design, 75 acute care nurses were sampled from July to October 2013. RESULTS: Attitudes toward evidence-based practice (EBP) were favorable, but knowledge of common research language was low and EBP confidence was reported as moderate. Evidence-based practice confidence had the strongest relationship to EBP use and was greatest in those who held professional certification and were more educated. CONCLUSION: Findings continue to demonstrate the need for new approaches to reduce the research-practice gap.

AIM: The aim of this study is to describe relationships among self-rated health, stress, sleep quality, loneliness, and self-esteem, in obese young adult women. BACKGROUND: Obesity has steadily increased among young adults and is a major predictor of self-rated health. METHODS: A sample of 68 obese (BMI 30 or higher, mean 35), young (18-34 years, mean 22) adult women were recruited from a health center. Survey data were gathered and analyzed using descriptive and bivariate procedures to assess relationships and group differences. RESULTS: Scores reflected stress, loneliness, poor sleep quality, and poor self-esteem. There were positive correlations among stress, loneliness, and sleep quality and, a high inverse correlation between loneliness and self-esteem. Those who ranked their health as poor differed on stress, loneliness, and self-esteem when compared to those with rankings of good/very good. CONCLUSIONS: Assessing and addressing stress, loneliness, sleep quality and self-esteem could lead to improved health outcomes in obese young women.

OBJECT: This population-based study examined obstructive sleep apnea (OSA) symptoms predictive of anxiety in middle-aged men. METHOD: Secondary analyses were conducted on the National Health and Nutrition Examination Survey (NHANES) 2007-2008 data using weighted samples and complex sample analysis techniques (unweighted N=1,217). FINDINGS: Nonrefreshing sleep (χ(2)=69.333, p<0.001), excessive daytime sleepiness (χ(2)=47.766, p<0.001), and sleep fragmentation (χ(2)=30.692, p<0.001) were significantly associated with anxiety. Nonrefreshing sleep (OR 3.582, p<0.001) and awakenings due to apneic episodes (OR 2.047, p=0.001) were predictive of anxiety. CONCLUSION: Comorbid anxiety and OSA symptoms are common and have implications for activities of daily living, social responsibilities, and quality of life. Screening for anxiety among men with OSA symptoms is recommended.

INTRODUCTION: Cyclic vomiting syndrome (CVS) is a disorder of gut-brain interaction often triggered by stress. Interventions such as meditation may improve psychological outcomes and health-related quality of life (HRQoL), but their efficacy and the underlying mechanism are unknown. METHODS: We conducted a 6-week single-arm pilot study to assess the effects of heartfulness meditation (HFM) in CVS using a custom-designed meditation app. Primary outcomes included state and trait anxiety and mood state changes pre vs post-meditation, and secondary outcomes were psychological distress, coping, sleep quality, and HRQoL at baseline and at weeks 3 and 6. Serum concentrations of endocannabinoids N -arachidonylethanolamine and 2-arachidonoylglycerol and related lipids were measured pre- and post-HFM at baseline and week 6. RESULTS: In 30 treatment completers, there was a significant improvement in state anxiety ( P < 0.001), total mood disturbance ( P < 0.001), and other mood states (all P values < 0.05) across the 3 time points. Trait anxiety was also improved at week 6. There was a significant improvement in psychological distress (Global Severity Index), sleep quality (daytime dysfunction), coping (using religion/spirituality), and HRQoL (mental and physical) across the 3 time points (all P < 0.05). Significant increases in N -arachidonylethanolamine and related lipids N -oleoylethanolamine and palmitoylethanolamide post vs pre-HFM were observed at week 6 ( P < 0.001, 0.002, 0.003, respectively). No adverse effects were noted. DISCUSSION: App-delivered HFM is feasible, safe, and effective and improves psychological outcomes and augments endocannabinoids. This provides insight into the mechanism underlying HFM and has potential for widespread use as a digital therapeutic in CVS and other disorder of gut-brain interaction.

OBJECTIVES: Chronic pancreatitis (CP) is an inflammatory disease affecting the absorption of fat-soluble nutrients. Signaling in pancreatic cells that lead to inflammation may be influenced by fatty acids (FAs) through diet and de novo lipogenesis. Here, we investigated the relationship between plasma FA composition in CP with heterogeneity of etiology and complications of CP. MATERIALS AND METHODS: Blood and clinical parameters were collected from subjects with CP (n = 47) and controls (n = 22). Plasma was analyzed for FA composition using gas chromatography and compared between controls and CP and within CP. RESULTS: Palmitic acid increased, and linoleic acid decreased in CP compared with controls. Correlations between age or body mass index and FAs are altered in CP compared with controls. Diabetes, pancreatic calcifications, and substance usage, but not exocrine pancreatic dysfunction, were associated with differences in oleic acid and linoleic acid relative abundance in CP. De novo lipogenesis index was increased in the plasma of subjects with CP compared with controls and in calcific CP compared with noncalcific CP. CONCLUSIONS: Fatty acids that are markers of de novo lipogenesis and linoleic acid are dysregulated in CP depending on the etiology or complication. These results enhance our understanding of CP and highlight potential pathways targeting FAs for treating CP.

Acute pancreatitis (AP) is an acute inflammatory disorder that is common, costly, and is increasing in incidence worldwide with over 300,000 hospitalizations occurring yearly in the United States alone. As its course and outcomes vary widely, a critical knowledge gap in the field has been a lack of accurate prognostic tools to forecast AP patients' outcomes. Despite several published studies in the last three decades, the predictive performance of published prognostic models has been found to be suboptimal. Recently, non-regression machine learning models (ML) have garnered intense interest in medicine for their potential for better predictive performance. Each year, an increasing number of AP models are being published. However, their methodologic quality relating to transparent reporting and risk of bias in study design has never been systematically appraised. Therefore, through collaboration between a group of clinicians and data scientists with appropriate content expertise, we will perform a systematic review of papers published between January 2021 and December 2023 containing artificial intelligence prognostic models in AP. To systematically assess these studies, the authors will leverage the CHARMS checklist, PROBAST tool for risk of bias assessment, and the most current version of the TRIPOD-AI.
