RESUMO
Background and Aims: The change in hepatocellular carcinoma (HCC) care continuum during the coronavirus disease 2019 (COVID-19) pandemic remains unknown at a national level in the United States. We sought to determine the impact of the pandemic on incident HCC cases, clinical characteristics, and treatment in the United States. Methods: Using the National Cancer Database, we analyzed incident HCC cases from 2010 to 2020. The incidence rate was calculated using the population data for each year from the census bureau. Joinpoint regression analysis was applied for trend analysis, and a polynomial regression model estimated the number of projected HCC cases in 2020 according to the trend of rates from 2010 to 2019. The distribution of cancer stage and treatment modality were assessed. Results: The pandemic led to a significant reduction in reported HCC cases, from 19,597 in 2019 to 16,188 in 2020. The projected number of HCC for 2020 was 19,011, corresponding to a 14.8% reduction in 2020. Extent of reduction in the number of incident HCC cases relative to estimated cases remains consistent in racial and ethnic subgroups. Despite underdiagnosis of HCC in 2020, proportion of patients with early tumor stage (30.5% for Tumour, Node, Metastasis stage 1) and curative treatment receipt (9.1% for surgical resection, 13% for ablation, 4.2% for liver transplant) for HCC remained stable in the first year of the COVID-19 pandemic. Conclusion: There was a significant reduction in HCC cases in 2020 compared to pre-COVID years. While tumor stage and proportion of patients receiving curative treatment remained stable, continued follow-up is needed to assess potential changes during subsequent years.
RESUMO
Importance: Chronic liver disease affects more than 1.5 billion adults worldwide, however the majority of cases are asymptomatic and undiagnosed. Echocardiography is broadly performed and visualizes the liver; but this information is not leveraged. Objective: To develop and evaluate a deep learning algorithm on echocardiography videos to enable opportunistic screening for chronic liver disease. Design: Retrospective observational cohorts. Setting: Two large urban academic medical centers. Participants: Adult patients who received echocardiography and abdominal imaging (either abdominal ultrasound or abdominal magnetic resonance imaging) with ≤30 days between tests, between July 4, 2012, to June 4, 2022. Exposure: Deep learning model predictions from a deep-learning computer vision pipeline that identifies subcostal view echocardiogram videos and detects the presence of cirrhosis or steatotic liver disease (SLD). Main Outcome and Measures: Clinical diagnosis by paired abdominal ultrasound or magnetic resonance imaging (MRI). Results: A total of 1,596,640 echocardiogram videos (66,922 studies from 24,276 patients) from Cedars-Sinai Medical Center (CSMC) were used to develop EchoNet-Liver, an automated pipeline that identifies high quality subcostal images from echocardiogram studies and detects the presence of cirrhosis or SLD. In the held-out CSMC test cohort, EchoNet-Liver was able to detect the presence of cirrhosis with an AUC of 0.837 (0.789 - 0.880) and SLD with an AUC of 0.799 (0.758 - 0.837). In a separate test cohort with paired abdominal MRIs, cirrhosis was detected with an AUC of 0.704 (0.689-0.718) and SLD was detected with an AUC of 0.726 (0.659-0.790). In an external test cohort of 106 patients (n = 5,280 videos), the model detected cirrhosis with an AUC of 0.830 (0.738 - 0.909) and SLD with an AUC of 0.768 (0.652 - 0.875). Conclusions and Relevance: Deep learning assessment of clinical echocardiography enables opportunistic screening of SLD and cirrhosis. Application of this algorithm may identify patients who may benefit from further diagnostic testing and treatment for chronic liver disease.
RESUMO
BACKGROUND: Serum AFP-L3%, AFP, and DCP are useful biomarkers for HCC detection, but their utility in assessing treatment response remains unknown. We aim to evaluate the accuracy of a biomarker model in the detection of posttreatment viable tumors. METHODS: For model derivation, recipients with HCC undergoing liver transplant from 2018 to 2022 who had biomarkers collected within 3 months before transplant were included. We developed a generalized linear model for detecting posttreatment viable tumors with the 3 biomarkers as covariates, which we termed the "LAD Score." An independent cohort of 117 patients with HCC was used for external validation. RESULTS: Among 205 recipients of transplant, 70.2% had evidence of viable tumor on explant. The median LAD score was higher among patients with viable versus nonviable tumors (1.06 vs. 0.465, p < 0.001). The LAD score had a sensitivity of 55.6% and a specificity of 85.1% at the cutoff of 0.927, which was more accurate than imaging for detecting posttreatment viable tumors (AUROC 0.736 vs. 0.643, respectively; p = 0.045). The superior performance of the LAD score over imaging is primarily driven by its greater accuracy in detecting tumors <2 cm in diameter (AUROC of the LAD score 0.721 vs. imaging 0.595, p = 0.02). In the validation data set, the LAD score had an AUROC of 0.832 (95% CI: 0.753, 0.911) with a sensitivity of 72.5% and a specificity of 89.4% at the cutoff of 0.927. CONCLUSIONS: Our findings suggest the utility of LAD score in treatment response assessment after locoregional therapy for HCC, particularly in detecting small tumors. A larger prospective study is in progress to validate its accuracy and evaluate its performance in recurrence monitoring.

BACKGROUND: Muscle cramps are common among persons with cirrhosis and are associated with poor health-related quality of life (HRQOL). Treatment options are limited. We compared stretching or meditation in a randomized-controlled trial (RCT). PATIENTS: We enrolled 98 patients with a history of >4 muscle cramps in the prior month from 7/22-7/23. We randomized patients 1:1 to stretching versus meditation for 35 days. Our primary outcome was the change in cramp severity measured by the visual analogue scale for cramps (VAS-cramps, scaled 0-10). Secondary outcomes included a patient global impression of change (PGIC), change in sleep quality and global HRQOL measured using the EQ-5D and VAS-global HRQOL. RESULTS: Overall, 48% of patients had cirrhosis, 40% had diabetes, 16% the median age was 63, most were women (67%) and 81% were college educated. Both arms experienced a reduction in cramp severity-a median of 1.44 (.58-2.29) points for stretching and 1.97 (1.01-2.93) points for meditation. These changes were significant changes from baseline (p = .001 for stretching, p < .0001 for meditation) but these changes were equivalent between arms (p = .4). The PGIC was improved: 1.33 (1.02-1.65) for stretching, 1.05 (.70-1.41) for meditation, p-difference .2. Sleep was also improved for both. HRQOL did not change according to the Eq5D; according to the VAS, HRQOL rose for meditation by 6 (.1-11.8) points but not for stretching. More patients recommended stretching than meditation (79.2% vs. 55.3%, p = .02). CONCLUSION: In a randomized trial, stretching and meditation both reduced cramp severity and improved sleep quality and global impression of change. While patients preferred stretching, there was no difference in effect between arms.
RESUMO
Introduction: The Hispanic population in the US faces a higher risk of nonalcoholic fatty liver disease (NAFLD). Multiple factors influence this risk, including genetics, environmental factors, and socioeconomic statuses. Inadequate access to nutritious foods, or food insecurity, is prevalent among Hispanic individuals and poses a metabolic risk for both the onset and development of NAFLD. Materials and Methods: We utilized the National Health and Nutrition Examination Survey (NHANES) 2017-2020 pre-pandemic data to analyze the association between Hispanic ethnicity, hepatic steatosis, fibrosis, and food insecurity. Vibration-controlled transient elastography (VCTE) was employed to assess liver stiffness (LSM) and controlled attenuation parameter (CAP) scores to determine fibrosis and steatosis, respectively. Linear and ordinal logistic regression models were applied to their continuous, log-transformed, and categorical forms, adjusting for demographics, metabolic comorbidities, and socioeconomic factors. Models were subsequently stratified based on food security statuses. Results: A total of 7396 Hispanic participants were included in the study. Under multivariable analysis, Hispanic individuals had higher CAP scores (Beta-coefficient: 10.2 dB/m, 95% CI: 6.1-14.4 dB/m, p = 0.001)) vs. non-Hispanic individuals, without statistically significant differences in fibrosis. Food-insecure participants exhibited higher CAP scores than their food-secure counterparts. After stratification, a stronger association between Hispanic ethnicity and CAP scores was evident in the food-insecure group (Beta-coefficient: 11.8 dB/m, 95% CI: 4.4-19.3 dB/m, p = 0.003). Discussion: This study demonstrates the heightened risk of hepatic steatosis among individuals with Hispanic ancestry in the US. The risk is exacerbated by food insecurity, particularly for Hispanic individuals. The contribution is linked to the dietary habits in this population that lead to metabolic risk factors associated with hepatic steatosis. Considering the rising prevalence of NAFLD and food insecurity, interventions focusing on nutritional support and healthcare access among this population could mitigate these burdens.
RESUMO
INTRODUCTION: Access to hepatocellular carcinoma (HCC) surveillance and treatments were disrupted during the coronavirus disease 2019 (COVID-19) pandemic. We aimed to characterize the impact of the pandemic on HCC incidence and mortality rates, treatment, and outcomes in the United States. METHODS: Two nationwide databases, the United States Cancer Statistics and the National Vital Statistics System, were used to investigate HCC incidence and mortality between 2001 and 2020. Trends in age-adjusted incidence rate (aIR) and adjusted mortality rate (aMR) were assessed using joinpoint analysis. The 2020 aIR and aMR were projected based on the prepandemic data and compared with actual values to assess the extent of underdiagnosis. We assessed differences in HCC characteristics, treatment, and overall survival between 2020 and 2018-2019. RESULTS: The aIR of HCC in 2020 was significantly reduced compared with 2019 (5.22 vs 6.03/100K person-years [PY]), representing a 12.2% decrease compared with the predicted aIR in 2020 (5.94/100K PY). The greatest extent of underdiagnosis was observed in Black (-14.87%) and Hispanic (-14.51%) individuals and those with localized HCC (-15.12%). Individuals staged as regional or distant HCC were also less likely to receive treatment in 2020. However, there was no significant difference in short-term overall survival in 2020 compared with 2018-2019, with HCC mortality rates remaining stable (aMR: 2.76 vs 2.73/100K PY in 2020 vs 2019). DISCUSSION: The COVID-19 pandemic resulted in underdiagnosis of HCC, particularly early stage disease and racial ethnic minorities, and underuse of HCC-directed treatment. Longer follow-up is needed to determine the impact of the COVID-19 pandemic on HCC-related mortality.

BACKGROUND AND AIMS: A new term, metabolic dysfunction-associated steatotic liver disease (MASLD), has been proposed by a multi-society expert panel. However, it remains unclear whether hepatic steatosis per se in MASLD contributes to an increased risk of mortality in individuals with any cardio-metabolic risk factor (CMRF), which is also a significant risk factor for increased mortality. This study aimed to compare all-cause and cause-specific mortality between the "MASLD/MetALD" and "no steatotic liver disease (SLD)" groups in individuals with any CMRF. APPROACH AND RESULTS: A population-based cohort study was conducted using 10,750 participants of the Third National Health and Nutrition Examination Survey. All-cause and cause-specific (cardiovascular, cancer, diabetes, and liver) mortality risks were compared between the "MASLD," "MetALD," and "no SLD" groups using the Cox proportional hazards model with complex survey design weights, adjusted for confounders. Over 26 years, the "MASLD" group did not show significantly increased all-cause (adjusted HR 1.04[95% CI: 0.95-1.14], p = 0.413), cardiovascular (0.88 [0.75-1.04], p = 0.139), or cancer (1.06[0.84-1.33], p = 0.635) mortality risk compared to the "no SLD" group in individuals with any CMRF. The MetALD group was associated with increased all-cause (1.41 [1.05-1.89], p = 0.022), cancer (2.35 [1.33-4.16], p = 0.004), and liver (15.04 [2.96-76.35], p = 0.002) mortality risk compared with the no SLD group. This trend was more pronounced in the MetALD group with advanced fibrosis assessed by Fibrosis-4 (FIB-4). CONCLUSIONS: In individuals with CMRF, the presence of steatotic liver disease (MASLD) alone did not increase the risk of mortality, except in cases with more alcohol consumption (MetALD). Therefore controlling metabolic risk factors and reducing alcohol consumption in people with MASLD or MetALD will be crucial steps to improve long-term health outcomes.
RESUMO
Introduction: Women experience excess cardiovascular risk compared to men in the setting of similar metabolic disease burden. This consistent finding could be related to sex differences in the vascular response to various forms of metabolic stress. In this study we examine the association of both systemic and organ-specific metabolic stress with vascular health in women and men. Methods: We conducted an observational study of 4,299 adult participants (52% women, aged 59±13 years) of the National Health and Nutrition Examination Survey (NHANES) 2017-2018 cohort and 110,225 adult outpatients (55% women, aged 64±16 years) of the Cedars-Sinai Medical Center (CSMC) 2019 cohort. We used natural splines to examine the association of systemic and organ-specific measures of metabolic stress including body mass index (BMI), hemoglobin A1c (HbA1c), hepatic FIB-4 score, and CKD-EPI estimated glomerular filtration rate (eGFR) on systolic blood pressure (SBP). Piecewise linear models were generated using normal value thresholds (BMI <25 kg/m 2 , HbA1c <5.7%, FIB-4 <1.3, and eGFR ≥90 ml/min), which approximated observed spline breakpoints. The primary outcome was increase in SBP (relative to a sex-specific physiologic baseline SBP) in association with increase in level of each metabolic measure. Results: Women compared to men demonstrated larger magnitudes and an earlier onset of increase in SBP per increment increase across all metabolic stress measures. The slope of SBP increase per increment of each metabolic measure was greater for women than men particularly for metabolic measures within the normal range, with slope differences of 1.71 mmHg per kg/m2 of BMI, 9.61 mmHg per %HbA1c, 6.45 mmHg per FIB-4 unit, and 0.37 mmHg per ml/min decrement of eGFR in the NHANES cohort (P difference <0.05 for all). Overall results were consistent in the CSMC cohort. Conclusions: Women exhibited greater vascular sensitivity in the setting of multiple types of metabolic stress, particularly in periods representing the transition from metabolic health to disease. These findings underscore the importance of involving early metabolic health interventions as part of efforts to mitigate vascular risks in both women and men.

RESUMO
Mushroom (amatoxin) poisoning from ingestion is a rare but life-threatening medical emergency characterized by gastrointestinal symptoms before progression to multisystem organ failure in severe cases. Many therapies of amatoxin intoxication have been described, including supportive care, medical therapies, detoxification strategies, and liver transplant. The evidence supporting these therapies remains limited due to the rarity of amatoxin poisoning and challenge of a timely diagnosis. We report a case of amatoxin poisoning in Los Angeles causing severe liver injury without acute liver failure treated successfully using medical therapies, gallbladder drainage, and plasma exchange.
