To identify medical phrases utilized by the critical care team that may have an unintended impact on the critically ill patient, we administered an anonymous survey to multi-professional critical care team members. We elicited examples of imprecise language that may have a negative emotional impact on the critically ill. Of the 1600 providers surveyed, 265 offered 1379 examples (912 unique) which were clustered into 5 categories. Medical jargon (eg, “riding the vent”) was most prevalent (n = 549). There were 217 negative suggestions (eg, “you will feel a stick and a burn”). Hyperboles (eg, “black cloud”) were common (n = 198) while homonyms (ie “he fibbed”) accounted for 150 examples. Phrases such as “code brown in there” were categorized as metonyms (n = 144). 121 metaphors/similes (eg, “rearranging deck chairs on the Titanic”) were provided. Phrases that have the potential to negatively impact critically ill patient perceptions are commonplace in critical care practice. Whether these everyday communication habits lead to an unintended nocebo effect on mental health outcomes of the critically ill deserves further study.

Importance Hispanic adults with type 2 diabetes (T2D) are more likely to develop complications and die from the disease than the US general population. Digital storytelling interventions are narrative-based videos elicited through a community-based participatory research approach to surface the authentic voices of participants overcoming obstacles to health-promoting behaviors that perpetuate health inequities; research on the effect of digital storytelling on T2D outcomes among Hispanic adults is lacking. Objective To assess the impact of a digital storytelling intervention on glycemic control and its acceptability among Hispanic patients with poorly controlled T2D. Design, Setting, and Participants This was a multicenter, randomized clinical trial conducted within 2 primary care networks in Minnesota and Arizona among Hispanic adults with poorly controlled T2D (hemoglobin A 1c level ≥8%). Enrollment and follow-up were conducted between February 14, 2019, and November 1, 2023. Intervention The intervention group viewed a 12-minute digital storytelling video. The video included 4 Spanish-language stories that reinforced 4 diabetes self-management behavioral goals (healthful diet for diabetes, physical activity, medication adherence, and glucose self-monitoring). The control group received printed, culturally tailored T2D education materials. Main Outcomes and Measures The primary outcome was the mean change from baseline to 3 months for hemoglobin A 1c levels, adjusting for baseline hemoglobin A 1c , age, gender, education, and income. Acceptability and narrative quality of the intervention were assessed through questionnaires. Results There were 451 study participants, with 227 (mean [SD] age, 54.3 [9.3] years; 158 [69.3%] women) randomized to the intervention group and 224 (mean [SD] age, 54.5 [9.1] years; 156 [69.3%] women) to the control group. Of these, 390 completed 3-month follow-up of the primary outcome (86% retention). There was a small improvement in the mean (SD) hemoglobin A 1c level in the intervention group compared with the control group in the adjusted model (9.1% [1.7] to 8.4% [1.6] vs 9.4% [1.8] to 8.8% [2.0]; P = .04] but not in the unadjusted model. Acceptability and narrative quality of the intervention were high. Conclusions and Relevance In this randomized clinical trial, a digital storytelling intervention developed with and for Hispanic adults with T2D was highly acceptable and feasibly implemented within primary care settings and resulted in a modest improvement of glycemic control. This was a highly scalable intervention that may be integrated into clinical practice as part of a longitudinal diabetes self-management program for Hispanic adults.

INTRODUCTION: Early neoplastic progression of Barrett's esophagus (BE) is often treated with endoscopic therapy. Although effective, some patients are refractory to therapy or recur after apparent eradication of the BE. The goal of this study was to determine whether genomic alterations within the treated BE may be associated with persistent or recurrent disease. METHODS: We performed DNA sequencing on pre-treatment esophageal samples from 45 patients who were successfully treated by endoscopic therapy and did not recur as well as pre-treatment and post-treatment samples from 40 patients who had persistent neoplasia and 21 patients who had recurrent neoplasia. The genomic alterations were compared between groups. RESULTS: The genomic landscape was similar between all groups. Patients with persistent disease were more likely to have pre-treatment alterations involving the receptor tyrosine kinase pathway ( P = 0.01), amplifications of oncogenes ( P = 0.01), and deletions of tumor suppressor genes ( P = 0.02). These associations were no longer significant after adjusting for patient age and BE length. More than half of patients with persistent (52.5%) or recurrent (57.2%) disease showed pre-treatment and post-treatment samples that shared at least 50% of their driver mutations. DISCUSSION: Pre-treatment samples were genomically similar between those who responded to endoscopic therapy and those who had persistent or recurrent disease, suggesting there is not a strong genomic component to treatment response. Although it was expected to find shared driver mutations in pre-treatment and post-treatment samples in patients with persistent disease, the finding that an equal number of patients with recurrent disease also showed this relation suggests that many recurrences represent undetected minimal residual disease.

INTRODUCTION: Pharmacologic therapies for symptoms of gastroparesis (GP) have limited efficacy, and it is difficult to predict which patients will respond. In this study, we implemented a machine learning model to predict the response to prokinetics and/or neuromodulators in patients with GP-like symptoms. METHODS: Subjects with suspected GP underwent simultaneous gastric emptying scintigraphy (GES) and wireless motility capsule and were followed for 6 months. Subjects were included if they were started on neuromodulators and/or prokinetics. Subjects were considered responders if their GP Cardinal Symptom Index at 6 months decreased by ≥1 from baseline. A machine learning model was trained using lasso regression, ridge regression, or random forest. Five-fold cross-validation was used to train the models, and the area under the receiver operator characteristic curve (AUC-ROC) was calculated using the test set. RESULTS: Of the 150 patients enrolled, 123 patients received either a prokinetic and/or a neuromodulator. Of the 123, 45 were considered responders and 78 were nonresponders. A ridge regression model with the variables, such as body mass index, infectious prodrome, delayed gastric emptying scintigraphy, no diabetes, had the highest AUC-ROC of 0.72. The model performed well for subjects on prokinetics without neuromodulators (AUC-ROC of 0.83) but poorly for those on neuromodulators without prokinetics. A separate model with gastric emptying time, duodenal motility index, no diabetes, and functional dyspepsia performed better (AUC-ROC of 0.75). DISCUSSION: This machine learning model has an acceptable accuracy in predicting those who will respond to neuromodulators and/or prokinetics. If validated, our model provides valuable data in predicting treatment outcomes in patients with GP-like symptoms.

Abstract Background Delirium is a common complication of older people in hospitals, rehabilitation and long-term facilities. Objective To assess the worldwide use of validated delirium assessment tools and the presence of delirium management protocols. Design Secondary analysis of a worldwide one-day point prevalence study on World Delirium Awareness Day, 15 March 2023. Setting Cross-sectional online survey including hospitals, rehabilitation and long-term facilities. Methods Participating clinicians reported data on delirium, the presence of protocols, delirium assessments, delirium-awareness interventions, non-pharmacological and pharmacological interventions, and ward/unit-specific barriers. Results Data from 44 countries, 1664 wards/units and 36 048 patients were analysed. Validated delirium assessments were used in 66.7% (n = 1110) of wards/units, 18.6% (n = 310) used personal judgement or no assessment, and 10% (n = 166) used other assessment methods. A delirium management protocol was reported in 66.8% (n = 1094) of wards/units. The presence of protocols for delirium management varied across continents, ranging from 21.6% (on 21/97 wards/units) in Africa to 90.4% (235/260) in Australia, similar to the use of validated delirium assessments with 29.6% (29/98) in Africa to 93.5% (116/124) in North America. Wards/units with a delirium management protocol [n = 1094/1664, 66.8%] were more likely to use a validated delirium test than those without a protocol [odds ratio 6.97 (95% confidence interval 5.289–9.185)]. The presence of a delirium protocol increased the chances for valid delirium assessment and, likely, evidence-based interventions. Conclusion Wards/units that reported the presence of delirium management protocols had a higher probability of using validated delirium assessments tools to assess for delirium.

Introduction: Immigrants to the United States often experience structural barriers to healthy nutrition and physical activity, which increases their risk of developing obesity, cardiovascular disease (CVD), and other chronic conditions. In our prior work with immigrant communities to co-develop interventions to improve nutrition and physical activity, mood was identified as a possible mediating factor. Hypothesis: We hypothesized that self-reported negative mood would be associated with unhealthy lifestyle behaviors such as poor nutrition and less physical activity. We also evaluated the relationship between mood and sociobehavioral factors such as social support and community belongingness. Methods: The Healthy Immigrant Community (HIC) study, set in Rochester, Minnesota and embedded with the Rochester Healthy Community Partnership, is a randomized, waitlist-controlled obesity and CVD risk reduction intervention. Community-based mentoring and education for health behaviors are delivered by trained health promoters, who are members of the immigrant populations, to their social networks. Baseline self-reported and biometric measures assessed nutrition, physical activity, self-efficacy, and sociobehavioral effects on healthy lifestyle behaviors. On a single-item rating of mood over the past 7 days, responses of poor or fair were considered “negative”, while good, very good, or excellent were considered “positive”. Results: The HIC study enrolled 475 adult participants; 268 Hispanic/Latino and 181 Somali participants completed baseline measures and were included in this analysis. Of the 449 participants, 107 (24%) reported “negative” mood. This group was more likely to be Hispanic/Latino (74%), female (68%), uninsured in the past 12 months (46%), or younger age (mean = 41 years; range = 18-79). Participants who endorsed negative mood at baseline had lower healthy nutrition scores ( p =0.02), lower physical activity scores ( p =0.03), and less confidence in eating healthily ( p =0.001). Those reporting negative mood also reported less support from family and friends to eat healthy ( p =<0.001) and be physically active ( p =0.01), accessed community resources for healthy eating ( p =0.001) and physical activity ( p =<0.01) less often, and reported less sense of belonging to their community ( p =0.01) than those with positive mood. Conclusion: Negative mood was significantly associated with eating a less healthy diet and being sedentary, lower confidence in maintaining a healthy diet, less perceived social support for healthy behaviors, and less sense of belonging to the community among Hispanic/Latino and Somali immigrants. Behavioral interventions designed to support a healthy lifestyle may benefit from incorporating culturally-aligned mood management and sociobehavioral strategies to reduce CVD risk and promote health equity in immigrant populations.

INTRODUCTION: Preliminary data suggest that an encapsulated balloon (EsoCheck), coupled with a 2 methylated DNA biomarker panel (EsoGuard), detects Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC) with high accuracy. The initial assay requires sample freezing upon collection. The purpose of this study was to assess a next-generation EsoCheck sampling device and EsoGuard assay in a much-enlarged multicenter study clinically enhanced by using a Clinical Laboratory Improvement Amendments of 1988-compliant assay and samples maintained at room temperature. METHODS: Cases with nondysplastic BE (NDBE), dysplastic BE (indefinite for dysplasia, low-grade dysplasia, high-grade dysplasia), EAC, junctional adenocarcinoma, plus endoscopy controls without esophageal intestinal metaplasia, were prospectively enrolled. Medical assistants at 6 institutions delivered the encapsulated balloon per orally with inflation in the stomach. The inflated balloon sampled the distal 5 cm of the esophagus and then was deflated and retracted into the capsule, preventing sample contamination. EsoGuard bisulfite sequencing assayed levels of methylated vimentin and methylated cyclin A1. RESULTS: A total of 243 evaluable patients—88 cases (median age 68 years, 78% men, 92% White) and 155 controls (median age 57 years, 41% men, 88% White)—underwent adequate EsoCheck sampling. The mean procedural time was approximately 3 minutes. Cases included 31 with NDBE, 16 with indefinite for dysplasia/low-grade dysplasia, 23 with high-grade dysplasia, and 18 with EAC/junctional adenocarcinoma. Thirty-seven NDBE and dysplastic BE cases (53%) were short-segment BE (<3 cm). Overall sensitivity was 85% (95% confidence interval 0.78–0.93) and specificity was 85% (95% confidence interval 0.79–0.90). Sensitivity for NDBE was 84%. EsoCheck/EsoGuard detected 100% of cancers (n = 18). DISCUSSION: EsoCheck/EsoGuard demonstrated high sensitivity and specificity in detecting BE and BE-related neoplasia.

Background: The primary role of natriuretic peptide receptor 3 (NPR3) is clearance of natriuretic peptides. Genetic variation in NPR3 has been associated with blood pressure regulation and obesity. Despite its importance, variation in NPR3 characterizing coding single nucleotide polymorphisms (SNPs) has not been addressed by resequencing the gene. Objective: We set out to identify and functionally characterize common variation in NPR3 in 3 ethnic groups. DNA samples from such subjects are studied because common genetic variation needs to be defined initially in “normal” individuals prior to studying drug effect and response. Also, rare variants identified by sequencing are enriched in complex disease traits. Methods and Results: DNA samples from 96 European-American, 96 African-American, and 96 Han Chinese-American healthy subjects were used to resequence NPR3. There were 105 polymorphisms identified of which 50 were novel, including 8 nonsynonymous (ns) SNPs of which 7 were novel. Expression constructs for the nsSNPs were created and HEK-293 cells were transfected with constructs for wild type (WT) and the variants. Recombinant proteins were analyzed by quantitative Western blot analysis. A significant reduction in NPR3 immunoreactive protein (60% or less of WT) was observed for the following variants Cys3, Arg146, Val499, and Ser477+Asp521. The Arg146 novel polymorphism resulted in the least protein expression (20% of WT). After treatment of WT and Arg146 cells with proteasome (MG132) and autophagy (3MA) inhibtors, it was determined that autophagy and not proteasomes plays an important role in the degradation of the Arg 146 variant protein. Modeling based on the NPR3 x-ray crystallography structure confirmed that the Arg146 variant were not compatible with WT conformation and could result in protein misfolding or instability. Conclusions: Multiple novel polymorphisms of NPR3 were identified in 3 ethnic groups. There were 4 variant receptors that displayed a significant decrease in NPR3 protein quantity, Arg146 being the variant with the least expression. Degradation of the variant Arg146 was mediated predominantly by autophagy. This SNP could have a significant effect on the metabolism of natriuretic peptides with clinical implications.
