This Letter to the Editor is a response to St-Jules and Fouque and their interpretation of postprandial hyperkalemia, especially regarding plant-based diets. Based on the reviewed literature review, potassium kinetic studies cited by the authors include only 1 study with a food-based intervention that actually showed reduced postprandial hyperkalemia with plant-based diets. The remainder of the studies used potassium salts or supplements that behave differently compared with whole plant foods. As such, we recommend avoiding restriction of whole plant foods in patients with chronic kidney disease when solely based on the theoretical risk of postprandial hyperkalemia.

IMPORTANCE:Whether endovascular thrombectomy (EVT) efficacy for patients with acute ischemic stroke and large cores varies depending on the extent of ischemic injury is uncertain. OBJECTIVE:To describe the relationship between imaging estimates of irreversibly injured brain (core) and at-risk regions (mismatch) and clinical outcomes and EVT treatment effect. DESIGN, SETTING, AND PARTICIPANTS:An exploratory analysis of the SELECT2 trial, which randomized 352 adults (18-85 years) with acute ischemic stroke due to occlusion of the internal carotid or middle cerebral artery (M1 segment) and large ischemic core to EVT vs medical management (MM), across 31 global centers between October 2019 and September 2022. INTERVENTION:EVT vs MM. MAIN OUTCOMES AND MEASURES:Primary outcome was functional outcome-90-day mRS score (0, no symptoms, to 6, death) assessed by adjusted generalized OR (aGenOR; values >1 represent more favorable outcomes). Benefit of EVT vs MM was assessed across levels of ischemic injury defined by noncontrast CT using ASPECTS score and by the volume of brain with severely reduced blood flow on CT perfusion or restricted diffusion on MRI. RESULTS:Among 352 patients randomized, 336 were analyzed (median age, 67 years; 139 [41.4%] female); of these, 168 (50%) were randomized to EVT, and 2 additional crossover MM patients received EVT. In an ordinal analysis of mRS at 90 days, EVT improved functional outcomes compared with MM within ASPECTS categories of 3 (aGenOR, 1.71 [95% CI, 1.04-2.81]), 4 (aGenOR, 2.01 [95% CI, 1.19-3.40]), and 5 (aGenOR, 1.85 [95% CI, 1.22-2.79]). Across strata for CT perfusion/MRI ischemic core volumes, aGenOR for EVT vs MM was 1.63 (95% CI, 1.23-2.16) for volumes ≥70 mL, 1.41 (95% CI, 0.99-2.02) for ≥100 mL, and 1.47 (95% CI, 0.84-2.56) for ≥150 mL. In the EVT group, outcomes worsened as ASPECTS decreased (aGenOR, 0.91 [95% CI, 0.82-1.00] per 1-point decrease) and as CT perfusion/MRI ischemic core volume increased (aGenOR, 0.92 [95% CI, 0.89-0.95] per 10-mL increase). No heterogeneity of EVT treatment effect was observed with or without mismatch, although few patients without mismatch were enrolled. CONCLUSION AND RELEVANCE:In this exploratory analysis of a randomized clinical trial of patients with extensive ischemic stroke, EVT improved clinical outcomes across a wide spectrum of infarct volumes, although enrollment of patients with minimal penumbra volume was low. In EVT-treated patients, clinical outcomes worsened as presenting ischemic injury estimates increased. TRIAL REGISTRATION:ClinicalTrials.gov Identifier: NCT03876457.

IMPORTANCE/UNASSIGNED:Racial implicit bias can contribute to health disparities through its negative influence on physician communication with Black patients. Interventions for physicians to address racial implicit bias in their clinical encounters are limited by a lack of high-fidelity (realistic) simulations to provide opportunities for skill development and practice. OBJECTIVE/UNASSIGNED:To describe the development and initial evaluation of a high-fidelity simulation of conditions under which physicians might be influenced by implicit racial bias. DESIGN, SETTING, AND PARTICIPANTS/UNASSIGNED:This cross-sectional study, performed on an online platform from March 1 to September 30, 2022, recruited a convenience sample of physician volunteers to pilot an educational simulation. EXPOSURES/UNASSIGNED:In the simulation exercise, physicians saw a 52-year-old male standardized patient (SP) (presenting as Black or White) seeking urgent care for epigastric pain, nausea, and vomiting. The case included cognitive stressors common to clinical environments, including clinical ambiguity, stress, time constraints, and interruptions. Physicians explained their diagnosis and treatment plan to the SP, wrote an assessment and management plan, completed surveys, and took the Race Implicit Association Test (IAT) and Race Medical Cooperativeness IAT. The SPs, blinded to the purpose of the study, assessed each physician's communication using skills checklists and global rating scales. MAIN OUTCOMES AND MEASURES/UNASSIGNED:Association between physicians' IAT scores and SP race with SP ratings of communication skills. RESULTS/UNASSIGNED:In 60 physicians (23 [38.3%] Asian, 4 [6.7%] Black, 23 [38.3%] White, and 10 [16.7%] other, including Latina/o/x, Middle Eastern, and multiracial; 31 [51.7%] female, 27 [45.0%] male, and 2 [3.3%] other), the interaction of physicians' Race IAT score and SP race was significant for overall communication (mean [SD] β = -1.29 [0.41]), all subdomains of communication (mean [SD] β = -1.17 [0.52] to -1.43 [0.59]), and overall global ratings (mean [SD] β = -1.09 [0.39]). Black SPs rated physicians lower on communication skills for a given pro-White Race IAT score than White SPs; White SP ratings increased as physicians' pro-White bias increased. CONCLUSIONS AND RELEVANCE/UNASSIGNED:In this cross-sectional study, a high-fidelity simulation calibrated with cognitive stressors common to clinical environments elicited the expected influence of racial implicit bias on physicians' communication skills. The outlined process and preliminary results can inform the development and evaluation of interventions that seek to address racial implicit bias in clinical encounters and improve physician communication with Black patients.

IMPORTANCE/UNASSIGNED:By law, patients have immediate access to discharge notes in their medical records. Technical language and abbreviations make notes difficult to read and understand for a typical patient. Large language models (LLMs [eg, GPT-4]) have the potential to transform these notes into patient-friendly language and format. OBJECTIVE/UNASSIGNED:To determine whether an LLM can transform discharge summaries into a format that is more readable and understandable. DESIGN, SETTING, AND PARTICIPANTS/UNASSIGNED:This cross-sectional study evaluated a sample of the discharge summaries of adult patients discharged from the General Internal Medicine service at NYU (New York University) Langone Health from June 1 to 30, 2023. Patients discharged as deceased were excluded. All discharge summaries were processed by the LLM between July 26 and August 5, 2023. INTERVENTIONS/UNASSIGNED:A secure Health Insurance Portability and Accountability Act-compliant platform, Microsoft Azure OpenAI, was used to transform these discharge summaries into a patient-friendly format between July 26 and August 5, 2023. MAIN OUTCOMES AND MEASURES/UNASSIGNED:Outcomes included readability as measured by Flesch-Kincaid Grade Level and understandability using Patient Education Materials Assessment Tool (PEMAT) scores. Readability and understandability of the original discharge summaries were compared with the transformed, patient-friendly discharge summaries created through the LLM. As balancing metrics, accuracy and completeness of the patient-friendly version were measured. RESULTS/UNASSIGNED:Discharge summaries of 50 patients (31 female [62.0%] and 19 male [38.0%]) were included. The median patient age was 65.5 (IQR, 59.0-77.5) years. Mean (SD) Flesch-Kincaid Grade Level was significantly lower in the patient-friendly discharge summaries (6.2 [0.5] vs 11.0 [1.5]; P < .001). PEMAT understandability scores were significantly higher for patient-friendly discharge summaries (81% vs 13%; P < .001). Two physicians reviewed each patient-friendly discharge summary for accuracy on a 6-point scale, with 54 of 100 reviews (54.0%) giving the best possible rating of 6. Summaries were rated entirely complete in 56 reviews (56.0%). Eighteen reviews noted safety concerns, mostly involving omissions, but also several inaccurate statements (termed hallucinations). CONCLUSIONS AND RELEVANCE/UNASSIGNED:The findings of this cross-sectional study of 50 discharge summaries suggest that LLMs can be used to translate discharge summaries into patient-friendly language and formats that are significantly more readable and understandable than discharge summaries as they appear in electronic health records. However, implementation will require improvements in accuracy, completeness, and safety. Given the safety concerns, initial implementation will require physician review.

BACKGROUND:The organizational studies' literature suggests that employees' expressions of voice and silence may be distinct concepts with different predictors. Organizational researchers also argue that both employees' voice and silence are related to burnout; however, these relationships have not been adequately examined in the healthcare context. OBJECTIVE:This study aimed to investigate the relationships among nurses' perceived impact, psychological safety, voice behaviors, and burnout using a theoretical model. Voice behaviors were conceptualized as voice and silence. DESIGN/METHODS:A cross-sectional, correlational study design was employed. SETTINGS/METHODS:Study data were collected in 34 general hospitals in South Korea. PARTICIPANTS/METHODS:A total of 1255 registered nurses providing direct care to patients were included in this study. METHODS:Using a convenience sampling method, a web-based survey was conducted to obtain data. All variables were measured using standardized instruments. A structural equation modeling analysis was employed to test a hypothesized model positing that perceived impact and psychological safety have both direct and indirect effects on nurse burnout through voice and silence. The response rate was 72.8 %. RESULTS:The findings supported the hypothesized model. Both perceived impact and psychological safety were positively related to expressions of voice, but both were negatively associated with silence. We also found that perceived impact was more strongly associated with voice than with silence, while psychological safety had a stronger impact on silence than on voice. Furthermore, voice reduced burnout, while silence increased it. Finally, perceived impact reduced burnout through voice (β = -0.10, 95 % confidence interval [-0.143, -0.059]) and silence (β = -0.04, 95 % confidence interval [-0.058, -0.014]), and psychological safety also decreased burnout through voice (β = -0.04, 95 % confidence interval [-0.057, -0.016]) and silence (β = -0.07, 95 % confidence interval [-0.101, -0.033]). Additional analyses revealed that prohibitive voice and silence significantly mediated the associations between psychological safety and burnout and perceived impact and burnout, but the mediating role of promotive voice was not statistically significant. CONCLUSIONS:It is important to recognize that voice and silence are distinct concepts. Moreover, to reduce nurse burnout, nurse managers and hospital administrators should develop separate strategies for promoting nurses' perceived impact and psychological safety, as their influences on voice and silence differ. REGISTRATION/BACKGROUND:Not applicable. TWEETABLE ABSTRACT/CONCLUSIONS:Voice and silence both influence nurse burnout. Separate strategies should be applied to voice and silence, as they are different concepts.

PURPOSE OF REVIEW/OBJECTIVE:Hypertension results in significant morbidity, mortality, and healthcare expenditures. Fortunately, it is largely preventable and treatable by implementing dietary interventions, though these remain underutilized. Here, we aim to explore the role of healthy dietary patterns in hypertension management and describe approaches for busy clinicians to address nutrition effectively and efficiently with patients. RECENT FINDINGS/RESULTS:DASH, Mediterranean, vegetarian, and vegan diets that include minimally processed, plant-based foods as core elements have consistently shown positive effects on hypertension. Recommendations that distill the most healthful components of these diets can significantly impact patient outcomes. Clinicians can harness evidence-based dietary assessment and counseling tools to implement and support behavioral changes, even during brief office visits. Healthful plant-based dietary patterns can often effectively prevent and treat hypertension. Clinicians may help improve patient outcomes by discussing evidence-based nutrition with their patients. Future work to promote infrastructural change that supports incorporating evidence-based nutrition into medical education, clinical care, and society at large can support these efforts.

We assessed factors associated with increased risk to loss of follow-up with infectious diseases staff in OPAT patients. Discharge to subacute healthcare facilities is strongly associated with loss to follow-up. We did not identify sociodemographic disparities. Poor communication between OPAT providers and subacute healthcare facilities remains a serious issue.

UNLABELLED:Mesenteric ischemia is a challenging condition characterized by insufficient blood perfusion to the mesentery and, consequently, intestinal tissues that continues to perplex clinicians. Despite its low prevalence, the condition's variable clinical presentation and elusive radiographic diagnosis can delay life-saving interventions in the acute setting and deteriorate the quality of life of patients when left undiagnosed or misdiagnosed. PURPOSE/OBJECTIVE:Review and summarize recent diagnostic updates and emergent intervention strategies for acute and chronic mesenteric ischemia. METHODS:A narrative review of all relevant studies from January 2022 through September 2023. RESULTS:A total of 11 studies from MEDLINE, supplemented with 44 studies from Google Scholar, were included in the review. CONCLUSIONS:Both acute and chronic mesenteric ischemia propose diagnostic and therapeutic challenges for interventionalists. Computed tomographic angiography remains the diagnostic modality of choice for both. Open surgical intervention remains the gold standard for acute mesenteric ischemia, while endovascular techniques are preferred for chronic mesenteric ischemia.

BACKGROUND:An optimal work environment for nurses is characterized primarily by appropriate staffing, good team relations, and support from the management staff. These factors are consistently associated with a positive assessment of patient safety by a hospital's employees and a reduction in hospital mortality rates. AIM/OBJECTIVE:To understand the relationships between the work environment as perceived by nurses on the 30-day mortality of patients treated in Polish hospitals. BACKGROUND:An optimal work environment for nurses is characterized primarily by appropriate staffing, good team relations, and support from the management staff. These factors are consistently associated with a positive assessment of patient safety by a hospital's employees and a reduction in hospital mortality rates. MATERIAL AND METHODS/METHODS:The analysis used discharge data from 108,284 patients hospitalized in internal medicine and surgery departments in 21 hospitals (with 24/7 operations) in Poland. Administrative data included coded data to estimate 30-day mortality. A Nurses' satisfaction questionnaire, including the PES-NWI scale and the SAQ questionnaire, was used to assess the work environment of nurses (n = 1,929). Correlations between variables were assessed using the Pearson coefficient. The analysis used a Poisson regression model, which belongs to the class of generalized linear models. RESULTS:A lower 30-day mortality rate amongst patients was found among those treated in hospitals where the personnel feel that they may question the decisions or actions of their superiors regarding the care provided (r = - 0.50); nurses are informed about changes introduced on the basis of reports about negligence and mistakes (r = - 0.50); the ward nurse is a good manager (r = - 0.41); nurses receive timely information from the head of the department that may have an impact on their work (r = - 0.41). CONCLUSIONS:Factors related to care during hospital stay such as the organization of care at the ward level, analysis of care errors, the number of staff providing direct patient care, informing nurses about mistakes without punishment, and the possibility of nurses challenging the decisions or actions of superiors, which concerns care providing, affect the 30-day mortality of patients after the end of hospitalization in Polish hospitals.
