Fatty Liver Education Promotes Physical Activity in Vulnerable Groups, Including Those With Unhealthy Alcohol Use.

BACKGROUND AND AIMS: Fatty liver disease (FLD), alcohol-associated and metabolically associated, often coexists. Increase in physical activity is associated with metabolic health and decreased FLD. We aimed to identify factors associated with physical activity and its improvement following FLD education in a racially diverse, vulnerable population. METHODS: From February 19, 2020 to December 30, 2022, 314 adults with FLD at safety-net hepatology clinics in San Francisco were surveyed at baseline, immediately after FLD education, and at 6-month follow-up. After collecting clinical and sociodemographic data, logistic regression (adjusted for age, sex, and race/ethnicity) assessed factors associated with physical activity at baseline and its improvement following education. RESULTS: Participant characteristics in those without vs with any physical activity were median age 49 vs 55 years, 64% vs 56% female, 66% vs 53% Hispanic race/ethnicity, 75% vs 55% obese, and 30% vs 22% consumed heavy alcohol, respectively. On multivariable analysis, older age was the only significant factor associated with physical activity at baseline (relative risk ratio 1.37 per decade increase, 95% confidence interval [CI] 1.07-1.75). Hispanic (vs non-Hispanic) participants had a significantly higher odds of improvement in physical activity (vs no change) 6 months after education (odds ratio 2.36, 95% CI 1.27-4.39). Among those with suboptimal or no physical activity at baseline, participants who consumed heavy alcohol (vs no drinking) had a significantly higher likelihood of achieving optimal physical activity following education (relative risk ratio 1.98, 95% CI 1.05-3.74). CONCLUSION: Despite social and structural barriers, FLD education increased uptake of physical activity in vulnerable populations, especially among Hispanic individuals and those consuming heavy alcohol. Implementation of patient-centered education is important for FLD management.

The Effect of Intersectionality on Attrition among US General Surgery Trainees.

OBJECTIVE: To examine the association between intersectionality of race, ethnicity, and sex on retention of U.S. general surgery residents. SUMMARY BACKGROUND DATA: There are limited data on the role that intersectionality plays on the US general surgery resident experience. METHODS: Analysis was performed using Association of American Medical Colleges (AAMC) data for general surgery residents who started their training between 2005-2015 (followed through completion). Regression analyses were used to assess demographic associations with time to attrition or successful completion of residency training. Associations between faculty and resident demographics were assessed. RESULTS: 25,029 residents were included. Over the decade-long study period, the number of underrepresented in medicine (UIM) residents as a percentage of all residents remained similar from 17% to 19% (P=0.24). The percent of UIM males starting training in 2005 was 11% and 12% in 2015 (P-value=0.38). UIM females comprised 5.5% of trainees in 2005 and increased to 6.9% (P-value=0.003) in 2015; and female non-UIM residents increased from 23 to 28% (P-value<0.001). The overall rate of resident attrition was 15%. UIM females had the highest yearly attrition rate at 21% compared to non-UIM males at 13% (HR 1.7, P<0.001). UIM females were more likely to leave residency compared to UIM males (HR: 1.5; P<0.001). The percent of UIM faculty was positively correlated with percent of UIM residents (r=0.64, P<0.001). CONCLUSIONS: Increasing intersectionality is positively associated with attrition during surgery residency. The diversity of faculty appears to be associated with resident diversity.

Clinically relevant cut-points for changes in the Liver Frailty Index are associated with waitlist mortality in patients with cirrhosis.

Physical frailty is a critical determinant of mortality in patients with cirrhosis and can be objectively measured using the Liver Frailty Index (LFI), which is potentially modifiable. We aimed to identify LFI cut-points associated with waitlist mortality. Ambulatory adults with cirrhosis without HCC awaiting liver transplantation from 9 centers from 2012 to 2021 for ≥3 months with ≥2 pre-liver transplantation LFI assessments were included. The primary explanatory variable was the change in LFI from first to second assessments per 3 months (∆LFI); we evaluated clinically relevant ∆LFI cut-points at 0.1, 0.2, 0.3, and 0.5. The primary outcome was waitlist mortality (death or delisting for being too sick), with transplant considered as a competing event. Among 1029 patients, the median (IQR) age was 58 (51-63) years; 42% were female; and the median lab Model for End-Stage Liver Disease-Sodium at first assessment was 18 (15-22). For each 0.1 improvement in ∆LFI, the risk of overall mortality decreased by 6% (cause-specific hazard ratio: 0.94, 95% CI: 0.92-0.97, p < 0.001). ∆LFI was associated with waitlist mortality at cut-points as low as 0.1 (cause-specific hazard ratio: 0.63, 95% CI: 0.46-0.87) and 0.2 (HR: 0.61, 95% CI: 0.42-0.87). An improvement in LFI per 3 months as small as 0.1 in the pre-liver transplantation period is associated with a clinically meaningful reduction in waitlist mortality. These data provide estimates of the reduction in mortality risk associated with improvements in LFI that can be used to assess the effectiveness of interventions targeting physical frailty in patients with cirrhosis.

Association between protein-energy malnutrition and healthcare use among adult patients after liver transplantation: A retrospective cohort study.

BACKGROUND: Protein-energy malnutrition is associated with poor surgical outcomes in liver transplant patients, but its impact on healthcare use has not been precisely characterized. We sought to quantify the burden of protein-energy malnutrition in hospitalized patients undergoing liver transplantation. METHODS: Current Procedural Terminology codes were used to identify United States hospitalizations between 2011 and 2018 for liver transplantation using the Nationwide Inpatient Sample. Patients <18 years old were excluded. Protein-energy malnutrition was identified by International Classification of Diseases Ninth and Tenth Revision codes. Multivariable regression was used to determine associations between protein-energy malnutrition and hospital outcomes, including hospital length of stay and hospital charges/costs. RESULTS: Of 9856 hospitalizations, 2835 (29%) had protein-energy malnutrition. Patients with protein-energy malnutrition had greater comorbidity burden and in-hospital acuity (eg, dialysis, sepsis, vasopressors, or mechanical ventilation). The adjusted median difference of protein-energy malnutrition vs no protein-energy malnutrition for length of stay was 6.4 days (95% CI, 5.6-7.1; P < 0.001), for hospital charges was $108,063 (95% CI, $93,172-$122,953; P < 0.001), and for hospital costs was $23,636 (95% CI, $20,390-$26,882; P < 0.001). CONCLUSION: Among patients undergoing liver transplantation, protein-energy malnutrition was associated with increased length of stay and hospital charges/costs. The additional cost of protein-energy malnutrition to liver transplantation programs was $23,636 per protein-energy malnutrition hospitalization. Our data justify the development of and investment in personnel and programs dedicated to reversing-or even preventing-protein-energy malnutrition in patients awaiting liver transplantation.

Outpatient mean arterial pressure: A potentially modifiable risk for acute kidney injury and death among patients with cirrhosis.

Mean arterial blood pressure (MAP), which decreases as portal hypertension progresses, may be a modifiable risk factor among patients with cirrhosis. We included adults enrolled in the Functional Assessment in Liver Transplantation study. We completed latent class trajectory analyses to define MAP trajectories. We completed time-dependent Cox-regression analyses to test the association between outpatient MAP and 3 cirrhosis-related outcomes: (1) stage 2 acute kidney injury (AKI), defined as a ≥200% increase in serum creatinine from baseline; (2) a 5-point increase in the MELD-Na score, defined as the incidence of increase from initial MELD-Na; (3) waitlist mortality, defined as death on the waitlist. For each outcome, we defined MAP cut points by determining the maximally selected Log-rank statistic after univariable Cox-regression analyses. Among the 1786 patients included in this analysis, our latent class trajectory analyses identified 3 specific outpatient MAP trajectories: "stable-low," "stable-high," and "increasing-to-decreasing." However, >80% of patients were in a "stable-low" trajectory. We found in adjusted analyses that outpatient MAP was associated with each of our outcomes: Stage 2 AKI (adjusted hazard ratio 0.88 per 10 mm Hg increase in MAP [95% CI: 0.79-0.99]); 5-point increase in MELD-Na (adjusted hazard ratio: 0.91 [95% CI: 0.86-0.96]; waitlist mortality (adjusted hazard ratio: 0.89 [95% CI: 0.81-0.96]). For each outcome, we found that an outpatient MAP of 82 mm Hg was most associated with outcomes ( p <0.05 for all). Our study informs the association between outpatient MAP and cirrhosis-related outcomes. These findings, coupled with the identification of specific thresholds, lay the foundation for the trial of targeted outpatient MAP modulation in patients with cirrhosis.

Surgeon Intersectionality and Academic Promotion and Retention in the US.

Introduction: Efforts have been made to increase the number of women and physicians who are underrepresented in medicine (UIM). However, surgery has been slow to diversify, and there are limited data surrounding the impact of intersectionality. Objective: To assess the combined association of race and ethnicity and sex with rates of promotion and attrition among US academic medical department of surgery faculty. Design, Setting, and Participants: This was a retrospective cohort study using faculty roster data from the Association of American Medical Colleges. All full-time academic department of surgery faculty with an appointment any time from January 1, 2005, to December 31, 2020, were included. Study data were analyzed from September 2022 to February 2023. Exposures: Full-time academic faculty in a department of surgery with a documented self-reported race, ethnicity, and sex within the designated categories of the faculty roster of Association of American Medical Colleges. Main Outcomes and Measures: Trends in race and ethnicity and sex, rates of promotion, and rates attrition from 2010 to 2020 were assessed with Kaplan-Meier and Cox time-to-event analyses. Results: A total of 31 045 faculty members (23 092 male [74%]; 7953 female [26%]) from 138 institutions were included. The mean (SD) program percentage of UIM male faculty increased from 8.4% (5.5%) in 2010 to 8.5% (6.2%) in 2020 (P < .001), whereas UIM female faculty members increased from 2.3% (2.6%) to 3.3% (2.5%) over the 10-year period (P < .001). The mean program percentage of non-UIM females increased at every rank (percentage point increase per year from 2010 to 2020 in instructor: 1.1; 95% CI, 0.73-1.5; assistant professor: 1.1; 95% CI, 0.93-1.3; associate professor: 0.55; 95% CI, 0.49-0.61; professor: 0.50; 95% CI, 0.41-0.60; all P < .001). There was no change in the mean program percentage of UIM female instructors or full professors. The mean (SD) percentage of UIM female assistant and associate professors increased from 3.0% (4.1%) to 5.0% (4.0%) and 1.6% (3.2%) to 2.2% (3.4%), respectively (P =.002). There was no change in the mean program percentage of UIM male instructors, associate, or full professors. Compared with non-Hispanic White males, Hispanic females were 32% less likely to be promoted within 10 years (hazard ratio [HR], 0.68; 95% CI, 0.54-0.86; P <.001), non-Hispanic White females were 25% less likely (HR, 0.75; 95% CI, 0.71-0.78; P <.001), Hispanic males were 15% less likely (HR, 0.85; 95% CI, 0.76-0.96; P =.007), and Asian females were 12% less likely (HR, 0.88; 95% CI, 0.80-0.96; P =.03). Non-UIM males had the shortest median (IQR) time to promotion, whereas non-UIM females had the longest (6.9 [6.8-7.0] years vs 7.2 [7.0-7.6] years, respectively; P < .001). After 10 years, 79% of non-UIM males (13 202 of 16 299), 71% of non-UIM females (3784 of 5330), 68% of UIM males (1738 of 2538), and 63% of UIM females (625 of 999) remained on the faculty. UIM females had a higher risk of attrition compared with non-UIM females (HR, 1.3; 95% CI, 1.1-1.5; P = .001) and UIM males (HR, 1.2; 95% CI, 1.0-1.4; P = .05). The mean (SE) time to attrition was shortest for UIM females and longest for non-UIM males (8.2 [0.14] years vs 9.0 [0.02] years, respectively; P < .001). Conclusion and Relevance: Results of this cohort study suggest that intersectionality was associated with promotion and attrition, with UIM females least likely to be promoted and at highest risk for attrition. Further efforts to understand these vulnerabilities are essential.

Problematic alcohol use and its impact on liver disease quality of life in a multicenter study of patients with cirrhosis.

BACKGROUND: Management of cirrhosis is challenging and has been complicated by the COVID-19 pandemic due to decreased access to care, increased psychological distress, and alcohol misuse. Recently, The National Institute on Alcohol Abuse and Alcoholism has broadened the definition of recovery from alcohol use disorder to include quality of life (QoL) as an indicator of recovery. This study examined the associations of alcohol-associated cirrhosis etiology and problematic drinking with liver disease QoL (LDQoL). METHODS: Patients with cirrhosis (N=329) were recruited from 3 sites (63% from 2 Veterans Affairs Health Care Systems and 37% from 1 safety net hospital) serving populations that are economically or socially marginalized. Cirrhosis etiology was ascertained by chart review of medical records. Problematic drinking was defined by ≥8 on the Alcohol Use Disorders Identification Test. Multivariable general linear modeling adjusting for age, sex, race/ethnicity, site, pandemic-related stress, and history of anxiety/depressive disorder were conducted. Sensitivity analyses further adjusted for indicators of liver disease severity. RESULTS: Participants were on average 64.6 years old, 17% female, 58% non-White, 44% with alcohol-associated cirrhosis, and 17% with problematic drinking. Problematic drinking was significantly associated with worse LDQoL scores in the overall scale and in the memory/concentration and health distress subscales. These associations remained significant after adjusting for indicators of liver disease severity, including Model for End-Stage Liver Disease-Sodium score and decompensated cirrhosis status. CONCLUSIONS: Among patients with cirrhosis, problematic drinking was associated with worse LDQoL, especially in the domains of memory/concentration and health distress. Assessment and awareness of cognitive deficits and negative emotionality within the context of cirrhosis and problematic drinking may help clinicians provide better integrated care for this population.

Adaptation of a health literacy screener for computerized, self-administered use by U.S. adults.

Objective: Health literacy is a critical health determinant, for which few computerized, self-administered assessments exist. This study adapted and tested the reliability of the Newest Vital Sign© (NVS) as a computerized, self-administered health literacy screener. Methods: Phase one involved 33 participants to create response options for a computerized, self-administered NVS (C-NVS). Phase two was a randomized crossover trial to test the consistency of C-NVS and original, interviewer-administered NVS (I-NVS) scores in 89 participants. Results: Linear mixed-effects regression model results showed a significant carryover effect (p < .001). Crossover trial data from time 1 showed that participants who initially received the C-NVS had significantly higher average scores (M = 5.7, SD = 0.6) than participants who received the I-NVS (M = 4.5, SD = 1.5; t(87) = 5.25, p < .001). Exploratory analysis results showed that when the washout period was longer than 33 days (75th percentile) the carryover effect was not statistically significant (p = .077). Conclusion and innovation: Findings suggest learning can occur when health literacy screeners are administered more than once in less than a month's time and computerized, self-administered health literacy screeners may produce ceiling effects. A universal precautions approach to health literacy therefore remains germane.

Factors associated with trauma recidivism in young children.

BACKGROUND: Trauma recidivism is associated with future trauma-associated morbidity and mortality. Previous evidence suggests that socioeconomic factors predict trauma recidivism in older children (10-18 years); however, risk factors in US children ≤10 have not been studied. We sought to determine the factors associated with trauma recidivism in young children ≤10. METHODS: We conducted a retrospective cohort study of pediatric trauma patients ≤10 years who presented to a single ACS-verified level I Pediatric Trauma Center from 7/1/2017 - 6/30/2021. All patients were evaluated for prior injury during trauma registry entry. Characteristics at the index injury were collected via chart review. Patients were geocoded to assess social vulnerability index (SVI). Logistic regression examined factors associated with recidivism. Best subset selection was used to compare multivariable models and identify the most predictive and parsimonious model. Statistical significance was set at p < 0.05. RESULTS: Of the 3,518 patients who presented in the study period, 169 (4.8%) experienced a prior injury. 76% (n = 128) had one prior injury presentation, 18% (n = 31) had 2 prior presentations, and 5.9% (n = 10) had ≥3. Falls were the most common mechanism in recidivists (63% vs. 52%, p = 0.009). Child physical abuse occurred in 6.5% of patients and 0.9% experienced penetrating injury. The majority (83%, n = 137) were discharged home from the ED. There was no significant difference in the frequency of penetrating injury and child physical abuse between recidivists and non-recidivists. Following logistic regression, the most parsimonious model demonstrated that recidivism was associated with comorbidities, age, falls, injury location, non-transfer, and racialization. No significant associations were found with SVI and insurance status. CONCLUSIONS: Medical comorbidities, young age, injury location, and falls were primarily associated with trauma recidivism. Support for parents of young children and those with special healthcare needs through injury prevention programs could reduce trauma recidivism in this population.Level of Evidence: III, Prognostic & Epidemiological.

Prevalence of cognitive impairment in liver transplant recipients.

Liver transplant (LT) recipients have a high burden of cognitive impairment risk factors identified in other populations, yet little work has explored cognition in the United States LT population. We characterized prevalence of cognitive impairment (CI) in LT recipients pre-LT and ≥3 months post-LT. Adult LT recipients with cirrhosis but without active pre-LT hepatic encephalopathy (HE) were screened for CI using the Montreal Cognitive Assessment (MoCA) for CI (MoCA <24) both pre-LT and ≥3 months post-LT. The association between cognitive performance and recipient characteristics was assessed using logistic regression. Of 107 LT recipients, 36% had pre-LT CI and 27% had post-LT CI [median (Q1-Q3) MoCA 26 (23-28)]. Each 1-point increase in pre-LT MoCA was associated with 26% lower odds of post-LT cognitive impairment (aOR .74, 95% CI .63-.87, p < .001), after adjusting for recipient age, history of HE, and time since LT. In this study of cirrhosis recipients without active pre-LT HE, cognitive impairment was prevalent before LT and remained prevalent ≥3 months after LT (27%), long after effects of portal hypertension on cognition would be expected to have resolved. Our data expose an urgent need for more comprehensive neurologic examination of LT recipients to better identify, characterize, and address predictors of post-LT cognitive impairment.
