Combined Effects of Air Pollution and Changes in Physical Activity With Cardiovascular Disease in Patients With Dyslipidemia.

Background: Sedentary behavior elevates cardiovascular disease (CVD) risk in patients with dyslipidemia. Increasing physical activity (PA) is recommended alongside pharmacological therapy to prevent CVD, though benefits across environmental conditions are unclear.

Methods And Results: We analyzed data from 113 918 newly diagnosed patients with dyslipidemia (2009-2012) without prior CVD, sourced from the Korea National Health Insurance Service.

Antibiotic Exposure and Risk of Parkinson Disease in South Korea: A Nationally Representative Retrospective Cohort Study.

Background And Objectives: Recent studies have suggested that antibiotics could be a contributing factor to Parkinson disease (PD), but validation in other population cohorts, such as Asians, is needed. This study examined the association between exposure to antibiotics and PD risk in the Korean population.

Methods: Using the National Health Insurance Service (NHIS) database, this population-level cohort research study from Korea included 298,379 people aged 40 years and older who underwent a national health examination in 2004-2005.

 crane flies (Diptera, Limoniidae) of Korea with identification key for all Palaearctic species.

Limnophilinae crane flies belonging to the genus Bergroth, 1891 of the Korean Peninsula were studied starting from 1937, but only one species (Alexander, 1923) has been recorded from North Korea so far. The genus was unknown from South Korea. Four species were found during our studies on the Peninsula, one of them from Jeju Island described as new, Podenas, Three species are recorded from both northern and southern parts of the Peninsula.

Association between antibiotics use and the risk of rheumatoid arthritis: a retrospective cohort study in South Korea.

Objectives: Certain studies propose that antibiotic use may influence rheumatoid arthritis (RA) incidence, but the clear association between antibiotics and RA remains unclear. Therefore, this study aimed to examine the relationship between antibiotics and RA risk to provide additional epidemiological evidence.

Methods: This population-based retrospective cohort study was conducted with adults aged 40 years or older using the Korean National Health Insurance Service (NHIS) database.

A Chromosome-Scale and Annotated Reference Genome Assembly of Plecia longiforceps Duda, 1934 (Diptera: Bibionidae).

Urbanization is a leading factor effecting global biodiversity, driving rapid evolutionary processes in the local biota. Species that adapt and proliferate in city environments can become pests, with human activities facilitating their dispersal and excessive outbreaks. Here we present the first genome data of Plecia longiforceps, a lovebug pest in Eastern Asia with intensive aggregations recently occurring in the Seoul Metropolitan Area of Korea.

Association between antibiotics use and osteoporotic fracture risk: a nationally representative retrospective cohort study.

Unlabelled: This population-based retrospective cohort study aimed to estimate the association between antibiotic exposure and osteoporotic fracture risk. Long-term antibiotic use was associated with the risk of osteoporotic fracture. An increase in the number of antibiotic classes prescribed may also be associated with an increased osteoporotic fracture risk.

Survival dynamics of stick insect and the impact of environmental factors on natural fungal infection during the rainy season.

Phasmatodea, commonly known as stick insects, are recognized as noteworthy pests globally, impacting agriculture and forest ecosystems. Among them, the outbreak of has emerged as a notable concern in East Asian forests. Recently, has been identified as utilizing stick insects as hosts.

Evolutionary changes in metabolic dysfunction-associated steatotic liver disease and risk of hepatocellular carcinoma: A nationwide cohort study.

Background/aims: To determine the association between evolutionary changes in metabolic dysfunction-associated steatotic liver disease (MASLD) status and the risk of hepatocellular carcinoma (HCC) in a nationwide population-based cohort.

Methods: Information on study participants was derived from the Korea National Health Insurance Service database. The study population consisted of 5,080,410 participants who underwent two consecutive biennial health screenings between 2009 and 2012.

Association between body composition and subsequent cardiovascular diseases among 5-year breast cancer survivors.

Background And Aims: Cardiovascular disease (CVD) remain one of the leading causes of mortality in breast cancer survivors. This study aimed to investigate the association between body composition and subsequent CVD in breast cancer survivors.

Methods And Results: A retrospective cohort study of more than 70 thousand 5-year breast cancer survivors aged 40 years or older was conducted using data from the National Health Insurance Service of South Korea.

Epidemiology and treatment outcome of ANCA-associated vasculitis in South Korea: a nationwide, population-based cohort study.

Objectives: To investigate the epidemiological features of granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) in South Korea.

Methods: We identified the index cases of GPA and MPA using the 2010-2018 Korean National Health Insurance Service database and the Rare Intractable Disease registry for the entire Korean population. Each disease's incidence and prevalence rates and trends over time were analysed.

Associations of cholecystectomy with metabolic health changes and incident cardiovascular disease: a retrospective cohort study.

Although some studies conducted about the risk of cholecystectomy and cardiovascular disease, there was a limit to explaining the relationship. We investigated the short-term and long-term relationship between cholecystectomy and cardiovascular disease, and evidence using the elements of the metabolic index as an intermediate step. It was a retrospective cohort study and we used the National Health Insurance Service database of South Korea between 2002 and 2015.

Association between antibiotic use and subsequent risk of prostate cancer: A retrospective cohort study in South Korea.

Objectives: Several studies suggest that antibiotic use may affect overall cancer incidence, but the association between antibiotics and prostate cancer is still unclear. This retrospective cohort study aimed to assess the association between antibiotics and the risk of prostate cancer.

Methods: A population-based retrospective cohort study was conducted using the Korean National Health Insurance Service (NHIS) database.

Reversal of nonalcoholic fatty liver disease reduces the risk of cardiovascular disease among Korean.

Nonalcoholic fatty liver disease (NAFLD) is considered an independent risk factor for the development of cardiovascular disease. However, the association between changes in NAFLD status and the risk of cardiovascular disease (CVD) remains uncertain. Starting January 1, 2013, participants were followed until the occurrence of CVD event, death, or December 31, 2020.

Association between antibiotics and asthma risk among adults aged over 40 years: a nationally representative retrospective cohort study.

Introduction: Several studies have reported that exposure to antibiotics can lead to asthma during early childhood. However, the association between antibiotic use and risk of asthma in the adult population remains unclear. This study aimed to investigate the association between antibiotic use and asthma in adults.
