Hepatitis C virus in Mexican Americans: a population-based study reveals relatively high prevalence and negative association with diabetes

Disparate outcomes in Hispanic patients with metabolic dysfunction-associated steatotic liver disease/steatohepatitis and type 2 diabetes: Large cohort study

BACKGROUND

Metabolic dysfunction-associated steatotic liver disease (MASLD) and metabolic dysfunction-associated steatohepatitis (MASH) are a growing health burden across a significant portion of the global patient population. However, these conditions seem to have disparate rates and outcomes between different ethnic populations. The combination of MASLD/MASH and type 2 diabetes increases the risk of hepatocellular carcinoma (HCC), and Hispanic patients experience the greatest burden, particularly those in South Texas.

AIM

To compare outcomes between Hispanic and non-Hispanic patients in the United States, while further focusing on the Hispanic population within Southeast Texas to determine whether the documented disparity in outcomes is a function of geographical circumstance or if there is a more widespread reason that all clinicians must account for in prognostic consideration.

METHODS

This cohort analysis was conducted with data obtained from TriNetX, LLC ("TriNetX"), a global federated health research network that provides access to deidentified medical records from healthcare organizations worldwide. Two cohort networks were used: University of Texas Medical Branch (UTMB) hospital and the United States national database collective to determine whether disparities were related to geographic regions, like Southeast Texas.

RESULTS

This study findings revealed Hispanics/Latinos have a statistically significant higher occurrence of HCC, type 2 diabetes mellitus, and liver fibrosis/cirrhosis in both the United States and the UTMB Hispanic/Latino groups. All-cause mortality in Hispanics/Latinos was lower within the United States group and not statistically elevated in the UTMB cohort.

CONCLUSION

This would appear to support that Hispanic patients in Southeast Texas are not uniquely affected compared to the national Hispanic population.

Border Health Training for Family Physicians: Is There a Need and Interest?

BACKGROUND AND OBJECTIVES

The United States-Mexico border has unique health care challenges due to a range of structural factors. Providers must be trained to address these barriers to improve health outcomes. Family medicine as a specialty has developed various training modalities to address needs for specific content training outside of core curriculum. Our study assessed perceived need, interest, content, and duration of specific border health training (BHT) for family medicine residents.

METHODS

Electronic surveys of potential family medicine trainees, faculty, and community physicians assessed appeal, feasibility, preferred content, and duration of BHT. We compared responses from participants from the border region, border states and the rest of the United States in their opinions about modality, duration, content of training, as well as perceived barriers.

RESULTS

Seventy-four percent of survey participants agreed that primary care on the border is unique; 79% indicated a need for specialized BHT. Most border-region faculty were interested in participating as instructors. Most residents expressed interest in short-term rotation experience, yet most faculty recommended postgraduate fellowship. Respondents selected language training (86%), medical knowledge (82%), care of asylum seekers (74%), ethics of cross-cultural work (72%), and advocacy (72%) as the top-five needed training areas.

CONCLUSIONS

Results of this study indicate a perceived need and sufficient interest in a range of BHT formats to warrant developing additional experiences. Developing a variety of training experiences can engage a wider audience interested in this topic; that should be done in a way ensuring maximum benefit to border-region communities.

The association between metabolic syndrome and Hepatitis C virus infection in the United States

PURPOSE

Hepatitis C virus (HCV) infection is the prevalent risk factor for chronic hepatitis, cirrhosis, and hepatocellular carcinoma (HCC) worldwide. The association between metabolic syndrome (MetS) and HCV infection has not been studied effectively, particularly among different ethnic/racial groups in the US.

METHODS

A retrospective cross-sectional study was conducted using data from the National Health and Nutrition Examination Survey (1999-2014). Unadjusted and adjusted associations were summarized using the prevalence ratio (PR) and 95% confidence interval (CI) after exploring possible interactions.

RESULTS

In the overall population, MetS was significantly associated with HCV infection with an interaction of age. After adjusting for all potential confounders, MetS was found to be significantly associated with HCV among non-obese and younger adults of age less than 60 years (PR 1.67, 95% CI 1.21-2.30, p = 0.002). MetS was also associated with an increased prevalence of HCV in each racial/ethnic group, while the association was strongly modified by age and obesity status of the subjects in different ethnic/racial groups.

CONCLUSIONS

MetS or its components are associated with an increased prevalence of HCV in some sub-populations of all ethnic/racial groups in the US. A better understanding of the pathophysiology of MetS associated with HCV is important as MetS may have a role in HCV infection treatment outcomes.

Disparities in liver cancer occurrence in the United States by race/ethnicity and state

Liver cancer is highly fatal, and death rates in the United States are increasing faster than for any other cancer, having doubled since the mid-1980s. In 2017, it is estimated that the disease will account for about 41,000 new cancer cases and 29,000 cancer deaths in the United States. In this article, data from the Surveillance, Epidemiology, and End Results (SEER) Program and the National Center for Health Statistics are used to provide an overview of liver cancer incidence, mortality, and survival rates and trends, including data by race/ethnicity and state. The prevalence of major risk factors for liver cancer is also reported based on national survey data from the Centers for Disease Control and Prevention. Despite the improvement in liver cancer survival in recent decades, only 1 in 5 patients survives 5 years after diagnosis. There is substantial disparity in liver cancer death rates by race/ethnicity (from 5.5 per 100,000 in non-Hispanic whites to 11.9 per 100,000 in American Indians/Alaska Natives) and state (from 3.8 per 100,000 in North Dakota to 9.6 per 100,000 in the District of Columbia) and by race/ethnicity within states. Differences in risk factor prevalence account for much of the observed variation in liver cancer rates. Thus, in contrast to the growing burden, a substantial proportion of liver cancer deaths could be averted, and existing disparities could be dramatically reduced, through the targeted application of existing knowledge in prevention, early detection, and treatment, including improvements in vaccination against hepatitis B virus, screening and treatment for chronic hepatitis C virus infections, maintaining a healthy body weight, access to high-quality diabetes care, preventing excessive alcohol drinking, and tobacco control, at both the state and national levels.

Burden of hepatocellular carcinoma among hispanics in South Texas: a systematic review

BACKGROUND

Hepatocellular carcinoma (HCC) is one of the fastest rising causes of cancer-related mortality in the United States (U.S.). Despite improved HCC screening and surveillance guidelines, significant race/ethnicity-specific disparities in hepatocellular carcinoma remain, disproportionately affecting at risk racial minorities in the U.S. The current review aims to provide an updated analysis on race/ethnicity-specific disparities in HCC epidemiology with a focus on predisposing risk factors.

CONCLUSION

Among different race/ethnicities in the U.S., Hispanics experienced the greatest burden of HCC, particularly those residing in South Texas. It is important to understand that the underlying etiologies for these disparities are complex and multi-factorial. Some of these risk factors for developing chronic liver disease include non-alcoholic fatty liver disease/non-alcoholic steatohepatitis and alcohol use. In addition, population genetics, acculturation of ethnic minorities, and access to healthcare may be further contributing to the observed disparities in HCC. By increasing awareness, improved modalities for screening and surveillance for HCC are important in guiding future research for targeted preventive and therapeutic interventions.
