Prevalence, trends, and characteristics of metabolic dysfunction-associated steatotic liver disease among the US population aged 12-79 years.

BACKGROUND AND AIMS: Clinical observation revealed an increase in metabolic dysfunction-associated steatotic liver disease (MASLD) prevalence among adults and adolescents and young adults (AYA). However, its prevalence trend in specific subgroups and its characteristics are unclear. APPROACH AND RESULTS: This cross-sectional study included adults and AYA aged 20-79 and 12-19 years, respectively, from the National Health and Nutrition Examination Survey from 1999 to 2018. MASLD was defined as US Fatty Liver Index ≥30 in adults and alanine amino transaminase elevation and obesity in AYA. Joinpoint and logistic regression were used to evaluate the MASLD prevalence trend and its associated characteristics. MASLD was diagnosed in 17 156 892 of 51 109 914 (33.6%) adults and 1 705 586 of 29 278 666 AYA (5.8%). During the study period, MASLD prevalence significantly increased from 30.8% to 37.7% ( P  < 0.01) in adults and in subgroups of female participants, individuals aged 20-45 and 61-79 years, and non-Hispanic white individuals. Conversely, MASLD prevalence did not significantly change in AYA (from 5.1% to 5.2%, P  = 0.139), except in the subgroup of Mexican Americans (from 8.2% to 10.8%, P  = 0.01). Among adults, high MASLD prevalence was associated with male sex, Mexican American ethnicity, age >50 years, being unmarried, poverty income ratio <130, poor or fair health condition, obesity or overweight, and chronic conditions. Among AYA, high MASLD prevalence was associated with male sex, poverty income ratio <130, and education. CONCLUSION: Accordingly, we concluded that health care providers should prevent and treat conditions associated with MASLD by raising awareness of the increasing trend of MASLD.

Utilization and impact of SLGT2 inhibitors among diabetes patients in a nationally representative survey: Findings from NHANES 2013-2020.

BACKGROUND AND AIMS: The purpose of this study is to examine patterns of utilization for antidiabetic medications among a nationally representative sample of the US population following the introduction of SGLT2 inhibitors in 2013. METHODS: The study utilized National Health and Nutrition Examination Survey (NHANES) data from 2013 to 2020 to identify adult patients with diabetes using antidiabetic medication. The proportion of patients with diabetes using different antidiabetic medications, including SGLT2 inhibitors, was plotted over time. To assess the statistical significance of the utilization trend of SGLT2 inhibitors and other oral antidiabetics, logistic regression models were employed. RESULTS: A weighted total of 26,421,357 individuals included in our study were diagnosed with diabetes. Among these, 18,751,659 diabetes patients were identified as medication users, with 1,058,686 (5.7 %) of them taking SGLT2 inhibitors. Over the 7-year study period, the percentage of patients taking SGLT2 inhibitors increased 21-fold, from 0.4 % in 2013-2014 to 9.4 % in 2017-2020. Despite this substantial increase, the utilization of other second-line antidiabetic agents, such as sulfonylureas, DPP-4 inhibitors, GLP-1 receptor agonists, and TZDs, remained relatively stable during the same period. CONCLUSIONS: SGLT2 inhibitor utilization has significantly increased among US diabetes patients; however, their rise has not substantially impacted the use of other second-line antidiabetic agents. Further research is needed to understand the social determinants and potential barriers affecting the broader adoption of these beneficial medications.

High rifaximin out-of-pocket costs are associated with decreased treatment retention among patients with hepatic encephalopathy.

BACKGROUND AND AIMS: Hepatic encephalopathy (HE) is associated with significant morbidity and mortality for those with cirrhosis. Despite the known benefits of rifaximin use for HE, treatment retention remains low. This study aimed to evaluate the impact of out-of-pocket (OOP) rifaximin cost on treatment retention among commercially insured patients in the United States. METHODS: Adult patients with cirrhosis and HE were identified from the IBM MarketScan claims database. Those who began rifaximin treatment between January 1, 2011, and December 1, 2021 were included. Regression models were used to analyze the relationship between patients' 30-day OOP rifaximin cost and rifaximin retention (≥80% eligible days with rifaximin supply) at 180, 360, and 540 days. Models were controlled for patient demographic and clinical characteristics including age, sex, comorbid conditions, Charlson comorbidity index (CCI), and lactulose use. RESULTS: A total of 6839 adult patients were included. Most patients were between 55 and 64 years (57.1%), male (60.4%), and living in urban settings (84.6%). Treatment retention was low for all time periods; retention rates for rifaximin were 42%, 25%, and 16% at 180, 360, and 540 days, respectively. In multivariable analysis, 30-day OOP costs of ≥ $150 were associated with a decreased likelihood of rifaximin retention at 180, 360, and 540 days [relative risk (RR) = 0.67, RR = 0.62, and R = 0.60, respectively]. Younger age was associated with reduced treatment retention for all time periods. Metastatic cancer and depression were associated with reduced treatment retention at 180 days (RR = 0.70 and RR = 0.87, respectively). CONCLUSIONS: Rates of rifaximin treatment retention are low despite the known benefits of rifaximin use for breakthrough HE. High 30-day OOP cost is associated with reduced rifaximin treatment retention.

Prevalence, trends, and characteristics of polypharmacy among US pregnant women aged 15 to 44 years: NHANES 1999 to 2016.

Polypharmacy has become a major health issue for pregnant woman due to the increased trend of medication use during pregnancy. However, data on medication use in pregnancy are limited since pregnant women are rarely included in clinical trials. Our study aimed to investigate the trends of and characteristics associated with polypharmacy among pregnant women in the US. This study was conducted using data from The National Health and Nutrition Examination Survey in the US. Nine The National Health and Nutrition Examination Survey cycles between 1999 and 2016 were used to identify pregnant women aged 15 to 44 years. Polypharmacy was defined as more than 1 medication prescription used during pregnancy. Descriptive statistics were used to report the prevalence and trends of polypharmacy. Multivariable logistic regression models were used to evaluate characteristics associated with polypharmacy among US pregnant women. Among 3,350,983 US pregnant women, about 7.4% of them (247,525) experienced polypharmacy. The prevalence of polypharmacy increased from 2.8% (1999-2000) to 10.0% (2015-2016) (P < .01) over-the time period examined in this study. Pregnant women were less likely to have experienced polypharmacy than were nonpregnant women (7.4% vs 23.5%, P < .01). Levothyroxine and albuterol were 2 prescriptions commonly taken by pregnant women. Pregnant women who were non-Hispanic white (P < .05) or had asthma (P < .05) or diabetes (P < .01) were more likely to report polypharmacy. Regarding personal characteristics, women with a poor or fair self-reported general health condition (odds ratio: 5.12, 95% confidence interval: 1.23-21.34) and those with chronic conditions (odds ratio: 6.91, 95% confidence interval: 3.08-15.50) were found to be associated with polypharmacy. An increased trend of polypharmacy was found in the US from 1999 to 2016. Non-Hispanic white pregnant women with a poor health status and chronic diseases were at an increased risk of polypharmacy.

SMAD3 Hypomethylation as a Biomarker for Early Prediction of Colorectal Cancer.

The incidence and mortality rates of colorectal cancer (CRC) have been high in recent years. Prevention and early detection are crucial for decreasing the death rate. Therefore, this study aims to characterize the alteration patterns of mothers against decapentaplegic homolog 3 (SMAD3) in patients with CRC and its applications in early detection by using a genome-wide methylation array to identify an aberrant hypomethylation site in the intron position of the SMAD3 gene. Quantitative methylation-specific polymerase chain reaction showed that hypomethylated SMAD3 occurred in 91.4% (501/548) of Taiwanese CRC tissues and 66.6% of benign tubular adenoma polyps. In addition, SMAD3 hypomethylation was observed in 94.7% of patients with CRC from The Cancer Genome Atlas dataset. A decrease in circulating cell-free methylation SMAD3 was detected in 70% of CRC patients but in only 20% of healthy individuals. SMAD3 mRNA expression was low in 42.9% of Taiwanese CRC tumor tissues but high in 29.4% of tumors compared with paired adjacent normal tissues. Hypomethylated SMAD3 was found in cancers of the digestive system, such as liver cancer, gastric cancer, and colorectal cancer, but not in breast cancer, endometrial cancer, and lung cancer. In conclusion, SMAD3 hypomethylation is a potential diagnostic marker for CRC in Western and Asian populations.
