Trends in alcohol use and alcoholic liver disease in South Korea: a nationwide cohort study.

BACKGROUND: There is a lack of national-level research on alcohol consumption and the epidemiology of alcoholic liver disease (ALD) in South Korea. This study aims to address the critical public health issue of ALD by focusing on its trends, incidence, and outcomes, using nationwide claims data. METHODS: Utilizing National Health Insurance Service data from 2011 to 2017, we calculated the population's overall drinking amount and the incidence of ALD based on ICD-10 diagnosis codes. RESULTS: From 2011 to 2017 in South Korea, social drinking increased from 15.7% to 16.5%, notably rising among women. High-risk drinking remained around 16.4%, decreasing in men aged 20-39 but not decreased in men aged 40-59 and steadily increased in women aged 20-59. The prevalence of ALD in high-risk drinkers (0.97%) was significantly higher than in social drinkers (0.16%). A 3-year follow-up revealed ALD incidence of 1.90% for high-risk drinkers and 0.31% for social drinkers. Women high-risk drinkers had a higher ALD risk ratio (6.08) than men (4.18). The economic burden of ALD was substantial, leading to higher healthcare costs and increased hospitalization. Progression rates to liver cirrhosis and hepatocellular carcinoma (HCC) in ALD patients were 23.3% and 2.8%, respectively, with no gender difference in cirrhosis progression. CONCLUSIONS: The study revealed a concerning rise in alcohol consumption among South Korean women and emphasizes the heightened health risks and economic burdens associated with high-risk drinking, especially concerning ALD and its complications.

The Epidemiology of Hepatitis B Virus Infection in Korea: 15-Year Analysis.

BACKGROUND: The purpose of this study is to investigate the epidemiological changes in chronic hepatitis B (CHB) and assess the impact of coronavirus disease 2019 (COVID-19) over the past 15 years in a region endemic to hepatitis B virus (HBV). METHODS: National Health Insurance Service claims data of hepatitis B patients spanning from 2007 to 2021 was utilized. To compare the characteristics of the hepatitis B group, a control group adjusted for age and gender through propensity score matching analysis was established. RESULTS: The number of patients with CHB has consistently increased over the past 15 years. The average age of the CHB patient group has shown a yearly rise, while the prevalence of male dominance has gradually diminished. The proportions of hepatocellular carcinoma, liver cirrhosis, and decompensation have exhibited a declining pattern, whereas the proportion of liver transplants has continuously risen. Patients with CHB have demonstrated significantly higher medical and medication costs compared to the control group. Moreover, patients with CHB have shown a higher prevalence of comorbidities along with a significantly higher rate of concomitant medication usage. During the COVID period, the HBV group experienced a substantial decrease in the number of outpatient visits and overall medical costs compared to the control group. CONCLUSION: The epidemiology of CHB has undergone significant changes over the past 15 years, encompassing shifts in prevalence, severity, medical costs, and comorbidities. Furthermore, the impact of COVID-19 has been observed to decrease healthcare utilization among patients with CHB when compared to controls.

The prognosis of patients with lung cancer admitted to the medical intensive care unit.

AIMS: Lung cancer remains the leading cause of cancer mortality worldwide. Despite their poor prognosis, patients with lung cancer are increasingly being admitted to the medical intensive care unit (MICU) for treatment of critical illnesses. The aim of this study was to assess the outcome of patients with lung cancer who are admitted to an MICU and to identify the measurable predictors of their MICU outcome. METHODS: We conducted retrospective analysis on 97 patients with lung cancer admitted to the MICU between 2007 and 2011. RESULTS: The mean age ± standard deviation was 71.8 ± 6.8 years. Of the 97 patients (82 male), 73 patients (75%) had non-small cell lung cancer stage IIIB, IV and 24 patients (25%) had small cell lung cancer. The intensive care unit mortality and in-hospital mortality rates were 53.6 and 61.8%. The main reasons for MICU admission were pneumonia (n = 51) and complication of cancer management (n = 45). The predictors of poor MICU outcome were history of diabetes mellitus (P = 0.028), Acute Physiology and Chronic Health Evaluation II score (P = 0.018), need for mechanical ventilation (P = 0.014), use of vasoactive agents (P < 0.0001), the presence of acute renal failure (P < 0.0001) and presence of multiorgan failure (P < 0.0001). CONCLUSIONS: We found that in-hospital mortality was not influenced by age, sex or performance status score of patients with lung cancer but increased with the severity of organ failure at MICU admission.

Could Transgastric Endoscopic Ultrasound-Guided Aspiration Alone Be Effective for the Treatment of Pancreatic Abscesses?

Drainage of pancreatic abscesses is required for effective control of sepsis. Endoscopic ultrasound (EUS)-guided endoscopic drainage is less invasive than surgery and prevents local complications related to percutaneous drainage. Endoscopic drainage with stent placement in the uncinate process of the pancreas is a technically difficult procedure. We report a case of pancreatic abscess treated by repeated EUS-guided aspiration and intravenous antibiotics without an indwelling drainage catheter or surgical intervention.
