Long-term impacts of COVID-19 in patients with prior heart failure in Korea: A nationwide cohort study using the common data model.

Limited data are available on the long-term prognosis and monitoring period after coronavirus disease 2019 (COVID-19) infection in the population with prior heart failure (HF). We aimed to exam the association of COVID-19 with clinical prognosis in populations with prior HF and evaluate prognosis within 30 days and 30 days to 1 year after infection. Based on insurance benefit claims sent to the Health Insurance Review and Assessment Service of Korea from January 2018 to April 2022, 9,822,577 patients were selected and converted to the Observational Medical Outcomes Partnership-common data model by the Big Data Department of Health Insurance Review and Assessment Service of Korea.

The Effect of Sodium-Glucose Cotransporter-2 Inhibitors on COVID-19 Patients with Type 2 Diabetes Mellitus: A Retrospective Cohort Study Using the Common Data Model.

Background: There is no clinical evidence about the effect of sodium-glucose cotransporter-2 (SGLT2) inhibitors on diabetic patients who have been diagnosed with coronavirus disease 19 (COVID-19).

Methods: The dataset is based on insurance benefit claims sent to the Health Insurance Review and Assessment Service of Korea from January, 2018 to April, 2022. Among 9,822,577 patients who were involved in the claims, diabetic patients were divided into two groups based on whether they had a prescription for an SGLT2 inhibitor.

Long-Term Clinical Implications of Atrial Fibrillation on Mortality in Patients Hospitalized with COVID-19: A Nationwide Cohort Study.

Background: Atrial fibrillation (AF) increases the risk of long-term mortality in patients hospitalized with Coronavirus Disease 2019 (COVID-19), but the evidence is limited.

Methods: This study used data from the Common Data Model of the Health Insurance Review and Assessment Service of Korea collected between 1 January 2020 and 30 April 2022. A total of 107,247 patients hospitalized with COVID-19 were included in this study.

The role of infectious disease consultations in the management of patients with fever in a long-term care facility.

Background: Infectious disease (ID) clinicians can provide essential services for febrile patients in tertiary hospitals. The aim of this study was to evaluate the role of ID consultations (IDC) in managing hospitalized patients with infections in an oriental medical hospital (OMH), which serves as a long-term care facility. To our knowledge, this is the first study on the role of IDCs in managing patients in an OMH.

Clinical characteristics of native vertebral osteomyelitis in patients with history of acupuncture.

Background: Considering that vertebral osteomyelitis (VO) can occur via various routes, it can be predicted that clinical characteristics may vary depending on the route of infection or risk factors of the disease. In this study, differences in clinical characteristics, causative pathogens, clinical features and prognosis were investigated in patients of native vertebral osteomyelitis with history of acupuncture.

Methods: This retrospective study was conducted at Kyung Hee University Hospital at Gangdong, Seoul.

The First Case of Infectious Spondylitis Caused by .

, a member of the genus , is a facultatively anaerobic, Gram-positive cocci. is a component of normal oral flora; however, it can become pathogenic and cause infections in patients with poor oral hygiene. A 78-year-old man was admitted to a hospital with a complaint of increasing posterior neck pain and lower back pain for 2 weeks.

Higher heart rate variability as a predictor of atrial fibrillation in patients with hypertension.

The autonomic nervous system (ANS) plays an important role in the initiation and maintenance of atrial fibrillation (AF). However, the meaning of higher heart rate variability (HRV) in predicting AF remains unclear. Among 2100 patients in the Holter registry, a total of 782 hypertensive patients were included in this study.

A case of Slackia exigua bacteremia associated with pyometra in a patient with poor dentition.

We report the first case of Slackia exigua bacteremia related to pyometra. Slackia exigua is an anaerobe that is usually found in the oral cavity and periodontal infections. After two months of treatment with antimicrobial agents, the patient recovered from infection.

Case Report of Infectious Spondylitis Caused by .

Background: species has not been considered a pathogen, but infections caused by this species are increasing. There are several cases of infections caused by but no case of infectious spondylitis has been reported yet.

Case Presentation: A 79-year-old female patient was hospitalized because of back pain for several months.

Clinical effectiveness of oral antimicrobial therapy for acute pyelonephritis caused by extended-spectrum β-lactamase-producing Enterobacteriales.

Infections caused by extended-spectrum β-lactamase-producing Enterobacteriales (ESBL-PE) are commonly treated with intravenous antibiotics. This study investigated whether oral antimicrobial therapy (OAT) is as effective as intravenous antimicrobial therapy (IVT) for acute pyelonephritis (APN) caused by ESBL-PE. A retrospective cohort of patients with APN caused by ESBL-PE was studied at a tertiary-care hospital from January 2014 through December 2016.

Comparative Evaluation Between the RealStar PCR Kit and the AmpliSens ()-FRT PCR Kit for Detecting in Non-HIV Immunocompromised Patients.

Background: Real-time PCR is more sensitive than microscopic examination for detecting . We compared the performance of two assays for detecting DNA: the RealStar PCR Kit 1.0 CE (Altona Diagnostics, Hamburg, Germany) and the AmpliSens ()-FRT PCR kit (InterLabService Ltd.

[The proportional mortality ratios of specific-cause mortality by occupation and education among men aged 20-64 in Korea (1993-2004)].

Objectives: This study investigated the relationship of occupational class and educational background with proportional mortality ratios in Korea.

Methods: Mortality was investigated using the entire registered death data from 1993 to 2004, obtained from the Korean National Statistics Office. Proportional mortality ratios (PMRs) for specific diseases were calculated according to the occupational class and educational background of men aged 20-64.
