Objectives:
Lonely death is defined as “a person living in a state of social isolation, disconnected from family, relatives, and others, who dies from suicide, illness, or other causes”. This study investigated the characteristics of individuals who die alone in Korea.
Methods:
We constructed a database of lonely death cases by linking data from the Korea Crime Scene Investigation Unit of the Korea National Police Agency with National Health Insurance Service (NHIS) records. A descriptive analysis was performed to evaluate the demographics, underlying diseases, and healthcare utilization patterns among lonely death cases.
Results:
Among the 3122 individuals identified as lonely death cases, 2621 (84.0%) were male and 501 (16.0%) were female. The most common age group was 50-59 years (n=930, 29.8%). The NHIS covered 2161 individuals (69.2%), whereas 961 individuals (30.8%) were enrolled in Medical Aid (MA). The highest number of lonely deaths occurred in Seoul areas, with 1468 cases (47.0%). Mood disorders were diagnosed in 1020 individuals (32.7%), and various alcohol-related diseases, including alcoholic liver disease, were also observed. Outpatient visits increased leading up to death but declined in the final 3 months, while hospitalizations decreased and emergency room visits slightly increased.
Conclusions
Most lonely death cases involved male in their 50s, with a disproportionately high number of MA beneficiaries compared to the general population. Many of these individuals also experienced mental health issues or alcohol-related disorders. Preventing social isolation and strengthening social safety nets are critical to reducing the occurrence of lonely deaths.

Background:
Chronic pain significantly affects daily activities, mental health, and the interpersonal relationships of patients. Consequently, physicians use various treatments to manage pain. This study investigated the perceptions of treatment, accompanying symptoms, and other problems in patients with chronic pain.
Methods:
The authors enrolled patients with chronic pain from 19 university hospitals in South Korea. Data was collected on age, gender, diagnosis, disease duration, severity of pain, perception of pain treatment, and accompanying symptoms or problems using an anonymous survey comprising 19 questions.
Results:
In total, 833 patients with chronic pain completed the survey, and 257 (31.0%) and 537 (64.5%) patientsexpressed concerns about the potential adverse effects of medication and opioid addiction, respectively. Personalitychanges such as irritability or anger were the most frequent accompanying symptoms in 507 (63.8%) patients, followed by depression and sleep disturbance in 462 (58.1%) and 450 (54.5%) patients, respectively. Depression (P = 0.001) and anxiety (P = 0.029) were more common among women, whereas divorce (P = 0.016), family conflict (P < 0.001), unemployment (P < 0.001), suicide attempts (P < 0.001), and restrictions on economic activity (P < 0.001) were more common among men. The frequency of accompanying symptoms, except for suicidal ideation,was higher in the younger patients aged ≤ 40 years than in the older patients aged > 40 years.
Conclusions
Many patients with chronic pain had concerns about adverse effects or medication tolerance and experienced anxiety, depression, or sleep disturbances. The prevalence of accompanying problems varies according to age and gender.

Epidemiology and Health 2024;46(1):e2024078-
OBJECTIVES:
This study investigated the prevalence, incidence, and prognosis of cardiac amyloidosis (CA) in Korea.
METHODS:
This retrospective nationwide population-based study used the Health Insurance Review and Assessment Service databases between 2008 and 2020. All patients diagnosed with amyloidosis were included, and those with a diagnosis of heart failure or cardiomyopathy were classified as having CA. Both the special code for amyloidosis (V121), which enables coverage of medical expenses, and the corresponding International Classification of Diseases, 10th revision codes for amyloidosis (E850- E854, E858, E859) were used to improve the reliability of amyloidosis diagnosis.
RESULTS:
Among 2,239 patients with amyloidosis, 758 met the criteria for CA (mean age, 64.4±11.9 years; 59.1% male). The mean age of patients with CA increased from 59.5±14.7 years in 2009 to 68.1±13.9 years in 2020. The incidence and prevalence increased from 0.09 (95% confidence interval [CI], 0.06 to 0.12) to 0.22 (95% CI, 0.18 to 0.27) per 100,000 person-years and 0.20 (95% CI, 0.16 to 0.25) to 1.30 (95% CI, 0.12 to 0.42) per 100,000 persons, respectively (all p<0.001). Patients with light-chain CA showed similar trends. In-hospital mortality decreased from 17.3% (95% CI, 9.23 to 29.6) to 6.10% (95% CI, 4.21 to 8.48) between 2009 and 2020. While age-specific in-hospital mortality was significantly higher in patients aged ≥70 years (p=0.004), no significant age-specific difference in in-hospital mortality was observed in patients with CA aged <70 years (p=0.981).
CONCLUSIONS
The prevalence and incidence of CA have increased in Korea, predominantly affecting older individuals, particularly males. Notably, in-hospital mortality decreased significantly.

Journal of Agricultural Medicine & Community Health 2024;49(3):194-204
Objectives:
This study aims to assess the current status of diabetes management among residents in 11 administrative regions (Si and Gun) of Chungcheongbuk-do, using data from the 2023 Community Health Survey, and to analyze variations according to the types of local governments.
Methods:
A total of 12,033 residents of Chungcheongbuk-do, aged 19 and older, were selected as study participants through the 2023 Korean Community Health Survey by Korea Centers for Disease Control and Prevention. Diabetes management indicators, including blood glucose awareness, treatment adherence, and complication prevention, were analyzed using SAS Enterprise Guide version 8.3, focusing on regional differences and patterns according to local government classifications.
Results:
Less than half of the residents of Chungcheongbuk-do were aware of their blood glucose levels, with considerable variation observed across regions. The overall proportion of individuals receiving appropriate diabetes management in Chungcheongbuk-do was 9.6%, but the rates differed significantly between regions. For instance, Yeongdong had the highest rate of diabetes self-management education (57.5%), while Chungju had the lowest (4.3%). The frequency of regular diabetic complication screenings, such as eye and kidney exams, remained suboptimal in most regions, with many falling below 50%. Even among regions with similar local government characteristics, substantial disparities in diabetes management were identified.
Conclusions
There is a pressing need for Chungcheongbuk-do and its local governments to enhance blood glucose awareness among residents and integrate comprehensive diabetes education into local health care strategies. Tailored health initiatives must be developed at the local level to improve diabetes management outcomes and reduce regional disparities, ultimately aiming to improve the quality of life for individuals with diabetes.
