RESUMO
BACKGROUND: Depression has been associated with nonalcoholic fatty liver disease (NAFLD). Data addressing the impact of depression on NAFLD-related mortality are evolving. We aim to study the association of depression in NAFLD and all-cause/cause-specific mortality in the United States. METHODS: A total of 11,877 individuals with NAFLD in the 2007-2016 National Health and Nutrition Examination Survey with the availability of linked mortality through 2019 were analysed. NAFLD was defined by utilizing the hepatic steatosis index in the absence of known causes of chronic liver disease. Depression and functional impairment due to depression were assessed using the Patient Health Questionnaire. RESULTS: During the median follow-up of 7.6 years, individuals with depression among individuals with NAFLD had a 35% higher all-cause mortality than those without depression (hazard ratio [HR]: 1.35, 95% confidence interval [CI]: 1.03-1.75) after adjusting for demographic, lifestyle and clinical risk factors. NAFLD with functional impairment due to depression had a 62% higher all-cause mortality than NAFLD without functional impairment (HR: 1.62, 95% CI: 1.10-2.39). Depression in NAFLD was associated with an approximately 50% increase in the risk for cardiovascular mortality, with a 2-fold higher cardiovascular mortality in those with functional impairment compared to those without (HR: 2.07, 95% CI: 1.30-3.30). However, there was no significant difference in cancer- and accident-related mortalities in NAFLD with or without depression. CONCLUSIONS: Depression among individuals with NAFLD was associated with a higher risk for all-cause and cardiovascular mortality in the United States.

BACKGROUND: People with human immunodeficiency virus (HIV) with and without hepatitis C virus (HCV) coinfection had poor outcomes after liver transplant (LT). Integrase strand transfer inhibitors (INSTIs) and direct-acting antivirals (DAAs) have changed the treatment landscape for HIV and HCV, respectively, but their impact on LT outcomes remains unclear. METHODS: This retrospective analysis of adults with HIV monoinfection (n = 246) and HIV/HCV coinfection (n = 286) who received LT compared mortality in patients with HIV who received LT before versus after approval of INSTIs and in patients with HIV/HCV coinfection who received LT before versus after approval of DAAs. In secondary analysis, we compared the outcomes in the different eras with those of propensity score-matched control cohorts of LT recipients without HIV or HCV infection. RESULTS: LT recipients with HIV monoinfection did not experience a significant improvement in survival between the pre-INSTI and INSTI recipients with HIV (adjusted hazard ratio [aHR], 0.70 [95% confidence interval {CI}, .36-1.34]). However, recipients with HIV/HCV coinfection in the DAA era had a 47% reduction (aHR, 0.53 [95% CI, .31-9.2] in 1-year mortality compared with coinfected recipients in the pre-DAA era. Compared to recipients without HIV or HCV, HIV-monoinfected recipients had higher mortality during the pre-INSTI era, but survival was comparable between groups during the INSTI era. HIV/HCV-coinfected recipients also experienced comparable survival during the DAA era compared to recipients without HCV or HIV. CONCLUSIONS: Post-LT survival for people with HIV monoinfection and HIV/HCV coinfection has improved with the introduction of INSTI and DAA therapy, suggesting that LT has become safer in these populations.

Livers from donors with positive hepatitis B surface antigens (HBsAg+) have been used to expand the donor pool; however, outcome data are limited. We aim to evaluate survival following liver transplant (LT) from HBsAg+ donors. Using the United Network for Organ Sharing registry, we identified HBsAg+ donors used for LT from 2009 to 2020. We used Kaplan-Meier survival and Cox proportional hazards regression to compare post-LT survival in hepatitis B virus-negative recipients who utilized HBsAg+ donors to propensity-matched cohorts who utilized other types of donors. From 2009-2020, 70 patients received HBsAg+ livers, and 58 of them did not carry a diagnosis of chronic hepatitis B virus. The 1- and 3-year post-LT survival for hepatitis B virus-negative patients who received livers from HBsAg+ donors were 96.6% and 91.4%, respectively, with no statistical differences compared with patients who received livers from hepatitis C virus viremic donors (96.5%/93.0%, P = .961/.427), donation after cardiac death donors (93.0%/86.0%, P = .651/.598), average-risk donors (89.5%/86.0%, P = 0.264/0.617), and a combination of extended-criteria donors, including donation after cardiac death, donor age over 70, and graft with greater than 30% steatosis (93.0%/91.2%, P = .621/.785). Recipients of HBsAg+ livers have similar post-LT survival compared with those receiving other types of grafts. Increasing the utilization of HBsAg+ livers could safely expand the donor pool.

Direct-acting antiviral (DAA) therapy for the treatment of chronic hepatitis C virus (HCV) infection is efficacious and well-tolerated in the post-liver transplant (LT) setting, prompting increased use of donors with HCV infection in patients waitlisted for LT.1,2 Although the incidence of nonviral hepatocellular carcinoma (HCC) is rising, HCV remains the most common risk factor for HCC among patients listed for LT in the United States.3 The use and outcomes of HCV-infected donors among patients with active HCV viremia waitlisted for (HCV-HCC) is lacking. Our aim was to evaluate post-LT survival among patients with HCV-HCC based on both recipient (active vs cured HCV) and donor (HCV+ vs HCV-) viremic status. Using the United Network for Organ Sharing (UNOS) registry, we analyzed all adult patients with HCV-HCC who underwent LT and had available recipient/donor HCV nucleic acid test (NAT) results from March 31, 2015 (date UNOS began reporting donor NAT) through June 30, 2021. Patients with acute liver failure, simultaneous organ transplant, previous LT, and those missing recipient and/or donor NAT results were excluded.

BACKGROUND & AIMS: Black patients with hepatocellular cancer (HCC), often attributed to hepatitis C virus (HCV) infection, have suboptimal survival following liver transplant (LT). We evaluated the impact of direct-acting antiviral (DAA) availability on racial and ethnic disparities in wait list burden post-LT survival for candidates with HCC. METHODS: Using the United Network for Organ Sharing registry, we identified patients with HCC who were listed and/or underwent LT from 2009 to 2020. Based on date of LT, patients were categorized into 2 era-based cohorts: the pre-DAA era (LT between 2009 and 2011) and DAA era (LT between 2015 and 2017, with follow-up through 2020). Kaplan-Meier and Cox proportional hazards analyses were used to compare post-LT survival, stratified by era and race and ethnicity. RESULTS: Annual wait list additions for HCV-related HCC decreased significantly in White and Hispanic patients during the DAA era, with no change (P = .14) in Black patients. Black patients had lower 3-year survival than White patients in the pre-DAA era (70.6% vs 80.1%, respectively; P < .001) but comparable survival in the DAA era (82.1% vs 85.5%, respectively; P = .16). 0n multivariable analysis, Black patients in the pre-DAA era had a 53% higher risk (adjusted hazard ratio [HR], 1.53; 95% confidence interval [CI], 1.28-1.84), for mortality than White patients, but mortality was comparable in the DAA era (adjusted HR, 1.23; 95% CI, 0.99-1.52). In a stratified analysis in Black patients, HCV-related HCC carried more than a 2-fold higher risk of mortality in the pre-DAA era (adjusted HR, 2.86; 95% CI, 1.50-5.43), which was reduced in the DAA era (adjusted HR, 1.34; 95% CI, 0.78-2.30). CONCLUSIONS: With the availability of DAA therapy, racial disparities in post-LT survival have improved.

There have been conflicting data regarding liver transplantation (LT) outcomes for hereditary hemochromatosis (HH), with no recent data on LT outcomes in patients with HH in the past decade. Using the United Network for Organ Sharing registry, we evaluated waitlist and post-LT survival in all adult patients listed for HH without concomitant liver disease from 2003 to 2019. Post-LT survival for HH was compared with a propensity-matched (recipient and donor factors) cohort of recipients with chronic liver disease (CLD). From 2003 to 2019, 862 patients with HH were listed for LT, of which 55.6% ( n = 479) patients underwent LT. The 1- and 5-year post-LT survival rates in patients with HH were 88.7% (95% confidence interval [CI], 85.4%-91.4%) and 77.5% (95% CI, 72.8%-81.4%), respectively, and were comparable with those in the propensity-matched CLD cohort ( p value = 0.96). Post-LT survival for HH was lower than for Wilson's disease, another hereditary metabolic liver disease with similar LT volume ( n = 365). Predictors for long-term (5-year) post-LT mortality included presence of portal vein thrombosis (hazard ratio [HR], 1.96; 95% CI, 1.07-3.58), obesity measurements greater than Class II (HR, 1.98; 95% CI, 1.16-3.39), and Karnofsky performance status (HR, 0.98; 95% CI, 0.97-0.99) at the time of LT. The leading cause of post-LT death ( n = 145) was malignancy (25.5%), whereas cardiac disease was the cause in less than 10% of recipients. In conclusion, short- and long-term survival rates for HH are excellent and comparable with those of other LT recipients. Improving extrahepatic metabolic factors and functional status in patients with HH prior to LT may improve outcomes.

BACKGROUND/AIMS: The global proportion of hepatocellular carcinoma (HCC) attributable to metabolic dysfunction-associated fatty liver disease (MAFLD) is unclear. The MAFLD diagnostic criteria allows objective diagnosis in the presence of steatosis plus defined markers of metabolic dysfunction, irrespective of concurrent liver disease. We aimed to determine the total global prevalence of MAFLD in HCC cohorts (total-MAFLD), including the proportion with MAFLD as their sole liver disease (single-MAFLD), and the proportion of those with concurrent liver disease where MAFLD was a contributary factor (mixed-MAFLD). METHODS: This systematic review and meta-analysis included studies systematically ascertaining MAFLD in HCC cohorts, defined using international expert panel criteria including ethnicity-specific BMI cut-offs. A comparison of clinical and tumour characteristics was performed between single-MAFLD, mixed-MAFLD, and non-MAFLD HCC. RESULTS: 22 studies (56,565 individuals with HCC) were included. Total and single-MAFLD HCC prevalence was 48.7% (95% confidence interval [CI] 34.5-63.0%) and 12.4% (95% CI 8.3-17.3%), respectively. In HCC due to chronic hepatitis B, C, and alcohol-related liver disease, mixed-MAFLD prevalence was 40.0% (95% CI 30.2-50.3%), 54.1% (95% CI 40.4-67.6%) and 64.3% (95% CI 52.7-75.0%), respectively. Mixed-MAFLD HCC had significantly higher likelihood of cirrhosis and lower likelihood of metastatic spread compared to single-MAFLD HCC, and a higher platelet count and lower likelihood of macrovascular invasion compared to non-MAFLD HCC. CONCLUSION: MAFLD is common as a sole aetiology, but more so as a co-factor in mixed-aetiology HCC, supporting the use of positive diagnostic criteria.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) has become a prevalent cause of chronic liver disease and ranks third among the causes of transplantation. In the United States alone, annual medical costs are approximately 100 billion dollars. Unfortunately, there is no Federal Drug Administration (FDA)-approved medication for its treatment. However, various clinical trials are investigating several therapeutic classes that could potentially treat NAFLD. It is valuable to have a compilation of the data available on their efficacy. AIM: To assess the efficacy of cyclophilin inhibitors, fibroblast growth factor 21 analogs (FGF21), and dual and pan peroxisome proliferator-activated receptor (PPAR) agonists for treating NAFLD. METHODS: A comprehensive literature search using keywords including cyclophilin inhibitor, FGF agonist, pan-PPAR agonists, dual-PPAR agonist, NAFLD, non-alcoholic steatohepatitis, and fatty liver was conducted on October 29, 2022, in PubMed, EMBASE, Cochrane Library, Scopus and Web of Science. Animal and human research, case reports, and published articles in English from all countries with patients aged 18 and above were included. Only articles with a National Institutes of Health (NIH) Quality Assessment score of five or higher out of eight points were included. Articles that were narrative or systematic reviews, abstracts, not in English, focused on patients under 18 years old, did not measure outcomes of interest, were inaccessible, or had a low NIH Quality Assessment score were excluded. Each article was screened by two independent researchers evaluating relevance and quality. Resources were scored based on the NIH Quality Assessment Score; then, pertinent data was extracted in a spreadsheet and descriptively analyzed. RESULTS: Of the 681 records screened, 29 met the necessary criteria and were included in this review. These records included 12 human studies and 17 animal studies. Specifically, there were four studies on cyclophilin inhibitors, four on FGF agonists/analogs, eleven on pan-PPAR agonists, and ten on dual-PPAR agonists. Different investigational products were assessed: The most common cyclophilin inhibitor was NV556; FGF agonists and analogs was Efruxifermin; pan-PPAR agonists was Lanifibranor; and dual-PPAR agonists was Saroglitazar. All classes were found to be statistically efficacious for the treatment of NAFLD, with animal studies demonstrating improvement in steatosis and/or fibrosis on biopsy and human studies evidencing improvement in different metabolic parameters and/or steatosis and fibrosis on FibroScan (P < 0.05). CONCLUSION: The data analyzed in this review showed clinically significant improvement in individual histological features of NAFLD in both animal and human trials for all four classes, as well as good safety profiles (P < 0.05). We believe this compilation of information will have positive clinical implications in obtaining an FDA-approved therapy for NAFLD.
RESUMO
Polymyositis is an inflammatory disease that causes bilateral proximal muscle weakness; unlike dermatomyositis, it is not usually associated with malignancy. However, there are a handful of case reports documenting polymyositis in patients with lymphoma, breast, lung, and bladder cancer. Here we report a case of metastatic pancreatic adenocarcinoma disguised by presenting as polymyositis. Clinical presentation, laboratory values, muscle biopsy, and imaging were all diagnostic of paraneoplastic polymyositis. The patient has significantly improved in symptoms are receiving systemic steroids and pancreaticoduodenectomy.
RESUMO
Objective: Telemedicine is being widely implemented in the COVID-19 pandemic to avoid infection risk. However, its effectiveness has not been evaluated, especially in developing countries, where it is invaluable for healthcare access. This study assesses physicians' and patients' perspectives of the usefulness and challenges of telemedicine in the gastroenterology department to identify its pitfalls. Methods: A cross-sectional telephonic survey was conducted on patients presenting to the gastroenterology department at a tertiary care hospital in Pakistan. An online survey was sent to physicians in the department. Results: A total of 160 patients participated, with a mean age 49.8 years, and 42.8% (n=68) males. There were 23.8% (n=38) initial visits and 76.3% (n=122) follow-ups. More than 85% of patients agreed telemedicine saved cost and time, 46.5% (n=74) said it improved healthcare access, and 76.3% (n=122) wanted to use it again. More than 80% were satisfied with the physician-patient interaction. Of the 7 physicians who participated, most felt telemedicine was inadequately facilitated, but felt comfortable with technology. Most felt it did not negatively affect healthcare, but thought it was complex for patients and that lack of physical interaction is a limitation. Nearly half were in favor of continuing its use after the pandemic. Conclusion: Telemedicine is an effective alternative to in-person visits. Patients find it convenient, with adequate interaction. Physicians have reservations that need addressal, such as poor administration. Most patients and half of physicians are welcome to using telemedicine in the post-COVID era.
RESUMO
To reduce the disparity in access to liver transplant (LT), United Network for Organ Sharing implemented an exception policy in May 2019, which capped hepatocellular carcinoma (HCC) exception score to the median Model for End-Stage Liver Disease (MELD) at transplant within the donor service area minus 3 points (MMaT-3) after the 6-mo wait period. We aimed to evaluate how this policy affected HCC waitlist outcomes. Methods: Using United Network for Organ Sharing data, we analyzed waitlist outcomes in HCC patients at the time they received exception points from in the pre-MMaT era (August 15, 2017, to November 15, 2018) and MMaT era (June 1, 2019, to August 30, 2020). Comparisons were made within the HCC group and HCC versus non-HCC (at time of listing) groups in the pre-MMaT and MMaT eras and regions were grouped as low, medium, and high MELD based on MMaT. Results: HCC group: LT probability within HCC patients decreased by 20% (subhazard ratio [sHR], 0.78; 95% confidence interval [CI], 0.74-0.85) between the eras and decreased by 41% in low MELD regions (sHR, 0.59; 95% CI, 0.52-0.66). Waitlist dropout was unchanged. Matched HCC versus non-HCC groups: HCC patients had 80% higher LT probability (sHR, 1.84; 95% CI, 1.71-1.99) than non-HCC patients in the pre-MMaT era; which decreased to a 14% higher LT probability in MMaT era. In low and medium regions, HCC patients had over twofold higher LT probability in the pre-MMaT era, which decreased to a ~20% higher probability (sHR, 1.14; 95% CI, 1.06-1.23) in the MMaT era. After implementation of the acuity circle policy, HCC patients had lower LT probability (sHR, 0.84; 95% CI, 0.74-0.94) than non-HCC patients. Conclusions: The geographic disparity between HCC and non-HCC patients has improved with the MMaT-3 policy. Despite lower LT probability for HCC patients, waitlist dropout was not adversely impacted.
RESUMO
INTRODUCTION: COVID-19-associated pulmonary sequalae have been increasingly reported after recovery from acute infection. Therefore, we aim to explore the charactersitics of persistent lung parenchymal abnormalities in patients with COVID-19. MATERIAL AND METHODS: An observational study was conducted in patients with post-COVID lung parenchymal abnormalities from April till September 2020. Patients ≥18 years of age with COVID-19 who were diagnosed as post-COVID lung parenchymal abnormality based on respiratory symptoms and HRCT chest imaging after the recovery of acute infection. Data was recorded on a structured pro forma, and descriptive analysis was performed using Stata version 12.1. RESULTS: A total of 30 patients with post-COVID lung parenchymal abnormalities were identified. The mean age of patients was 59.1 (SD 12.6), and 27 (90.0%) were males. Four HRCT patterns of lung parenchymal abnormalities were seen; organizing pneumonia in 10 (33.3%), nonspecific interstitial pneumonitis in 17 (56.7%), usual interstitial pneumonitis in 12 (40.0%) and probable usual interstitial pneumonitis in 14 (46.7%). Diffuse involvement was found in 15 (50.0%) patients, while peripheral predominance in 15 (50.0%), and other significant findings were seen in 8 (26.7%) patients. All individuals were treated with corticosteroids. The case fatality rate was 16.7%. Amongst the survivors, 32.0% recovered completely, 36.0% improved, while 32.0% of the patients had static or progressive disease. CONCLUSION: This is the first study from Southeast Asia that identified post-COVID lung parenchymal abnormalities in patients who had no pre-existing lung disease highlighting the importance of timely recognition and treatment of this entity that might lead to fatal outcome.

BACKGROUND: Glioblastoma multiforme (GBM) is the most malignant, aggressive and common form of primary brain cancer. Currently, GBM is considered to be a homogenous mass as all its margins are treated equally at the time of resection. However, it is not known whether radiologically distinct regions of GBM are also distinct at molecular level. We conducted this study to see if radiologically distinct regions were also different at the molecular level. METHODS: In 20 patients, MRI derived variance known as Apparent Diffusion Coefficient (ADC) was plotted against Contrast Enhancement (CE). Four radiologically distinct regions were identified: 1) high ADC and low CE; 2) low ADC and low CE; 3) high ADC and high CE; and 4) low ADC and high CE. Biopsy samples were collected from these four regions of interest in each patient and immunohistochemistry was conducted to characterize cellular features and identify oncogene and stem cell marker expressing cells. RESULTS: Markedly increased nuclear pleomorphism, cellularity and necrosis were seen in region 2. Oncogene IDH was expressed in all regions, however, it was highest in region 4. Stem cell marker, CD44 expression was highest in region 1 and lowest in region 2 and 3. The expression of CD133 was highest in region 3. CONCLUSIONS: This study shows that ADC/CE plot can divide GBM into four regions, whose heterogeneity is evidenced by differential expression of nuclear pleomorphism, necrosis, cellularity and mitotic rate as well as the expression of oncogene and stem cell markers.

Linezolid is a frequently prescribed antibiotic for chronic infection suppression, such as in prosthetic joint infections. While well tolerated, its prolonged use can increase the risk of rare and serious side effects. We present a case of linezolid toxicity presenting with a constellation of adverse effects including bone marrow suppression, lactic acidosis, and drug-induced liver injury. Our case highlights the increased risk of acute multiorgan failure in patients using the antibiotic for extended durations, notably those with preexisting comorbidities.
