Mortality Outcomes and Contributing Risk Factors in Patients with Hospital-Associated Disability.

: Hospital-associated disability (HAD), a functional decline following acute hospitalization, is a common complication associated with mortality and unfavorable prognoses in patients admitted to acute care hospitals. However, few studies have investigated mortality and associated factors in patients with HAD and have been limited by inconsistent HAD assessment tools and criteria. This study investigated mortality and risk factors in patients with HAD using specific criteria.

Treatment, Education, and Prognosis of Slow Learners (Borderline Intelligence).

Objectives: Borderline intelligence has been excluded from formal diagnostic systems and not included in disability diagnoses, leaving gaps in treatment, education, and social welfare despite various functional impairments. Therefore, we aimed to shed light on ways to enhance the intelligence and functioning of individuals with borderline intelligence by reviewing research on its progression, education, and treatment.

Methods: Ten studies that met the inclusion and exclusion criteria were included in the final literature review and analyzed according to detailed topics (participant characteristics, design, and results).

Effect of Rumen-Protected L-Tryptophan or L-Ascorbic Acid on Plasma Metabolites and Milk Production Characteristics of Lactating Holstein Cows during Summer Conditions.

This study investigated the effects of rumen-protected L-tryptophan or L-ascorbic acid supplementation on the productivity of lactating Holstein cows during a high-temperature period. Thirty cows were assigned to three dietary groups: control (CON), treatment 1 (TRT 1; rumen-protected L-tryptophan, 20 g/cow/d), and treatment 2 (TRT 2; rumen-protected L-ascorbic acid, 20 g/cow/d). As the high-temperature period progressed, the decrease in milk yield and dry matter intake (DMI) in the TRT 1 and TRT 2 groups was lower than that in the CON group.

represents one of the leading causes of bacterial gastroenteritis in humans and is primarily linked to chicken meat contamination. In the present study, we analyzed the virulence and survival genes, antimicrobial resistance, and the clonal distribution of 50 isolates obtained from various sources in 14 chicken slaughterhouses across 8 provinces in South Korea from 2019 to 2022. Furthermore, we determined their genetic relatedness to human-derived isolates registered in PubMLST using multilocus sequence typing (MLST).

Predicting delirium and the effects of medications in hospitalized COVID-19 patients using machine learning: A retrospective study within the Korean Multidisciplinary Cohort for Delirium Prevention (KoMCoDe).

Objective: Delirium is commonly reported from the inpatients with Coronavirus disease 2019 (COVID-19) infection. As delirium is closely associated with adverse clinical outcomes, prediction and prevention of delirium is critical. We developed a machine learning (ML) model to predict delirium in hospitalized patients with COVID-19 and to identify modifiable factors to prevent delirium.

Lobeglitazone inhibits LPS-induced NLRP3 inflammasome activation and inflammation in the liver.

Liver inflammation is a common feature of chronic liver disease and is often associated with increased exposure of the liver to lipopolysaccharide (LPS). Kupffer cells (KCs) are macrophages in the liver and produce various cytokines. Activation of KCs through the NLRP3 inflammasome pathway leads to release of proinflammatory cytokines and induces hepatocyte injury and hepatic stellate cell (HSC) activation.

How Can We Deal with Psychosocial Issues in an Emerging Infectious Disease Outbreak? Lessons from a Qualitative Study for the MERS Outbreak in Korea.

Background: The 2015 Middle East respiratory syndrome (MERS) coronavirus outbreak in Korea led to profound emotional and social burdens, especially in patients and health care professionals.

Materials And Methods: Focus group interviews were conducted with 2 patients, 1 family member and 6 health care professionals about psychological distress related to MERS in 2017 and analyzed the interview data using the consensual qualitative research method.

Results: Four domains and 17 core ideas were identified within three interview groups, including psychological distress during the outbreak, problems regarding the response to the outbreak, positive experiences, and future directions for enhancing intervention to improve mental health and prevent psychosocial problems during the outbreak.

Work values and communication styles among Generation X, Y, and Z nurses: A cross-sectional study.

Aim: To compare and contrast nurses' work values and communication styles across Generation X, Y, and Z.

Background: Intergenerational differences in the work values of nurses are well known, but the commonalities remain largely uninvestigated. It is also unclear if there are intergenerational differences and commonalities in the rhetorical communication style of nurses.

Unusual skin pigmentation after unilateral adrenalectomy due to pheochromocytoma: a case report.

Background: Skin pigmentation after adrenalectomy occurs due to an increase in adrenocorticotropic hormone (ACTH) following adrenal insufficiency. ACTH-induced pigmentation usually appears as generalized hyperpigmentation and is known to appear after bilateral adrenalectomy. We report a case of unusual transient hyperpigmentation that developed immediately after unilateral adrenalectomy for pheochromocytoma and spontaneously resolved without corticosteroid supplementation.

Guidelines for Infection Control and Burnout Prevention in Healthcare Workers Responding to COVID-19.

During the coronavirus disease 2019 (COVID-19) pandemic, frontline healthcare workers (HCWs) suffered more distress from the possibility of contracting the virus, quarantine, social stigma, and prejudice against their families. Many studies have investigated the impact of the pandemic on HCWs; however, studies or guidelines presenting strategies to overcome these challenges are lacking. As part of a 2020 research project supported by the Ministry of Health and Welfare, titled "Health impact assessment of healthcare workers undertaking coronavirus disease 2019 treatment and management in Korea: Identifying problems and researching effective solutions" (HC20C0003), we created guidelines to respond to serious problems posed by infection control.

Time-Series Trends of Depressive Levels of Korean Adults During the 2020 COVID-19 Pandemic in South Korea.

Objective: This study aimed to observe the changes in people's depressive levels over 9 months since the coronavirus disease of 2019 (COVID-19) outbreak as well as to identify the predictors of people's depressive levels including COVID-19 infection fear in the context of South Korea in 2020.

Methods: For these purposes, four cross-sectional surveys were periodically implemented from March to December 2020. We randomly recruited 6,142 Korean adults (aged 19 to 70) by using a quota survey.

Fat mass index and airway hyperresponsiveness in Korean adults.

Objective: Airway hyperresponsiveness (AHR) is associated with asthma and obesity, which is defined as a high body mass index. Body mass mainly comprises fat mass (FM) and muscle mass (MM), which are independent of each other. We investigated the effect of changes in FM over time on the development of asymptomatic AHR in adults.

Correlates of burnout among healthcare workers during the COVID-19 pandemic in South Korea.

Burnout is a form of negative emotional and physical response to job stress. This study aimed to investigate the prevalence of burnout among healthcare workers responding to the coronavirus disease 2019 (COVID-19) outbreak in Korea and to explore correlates of burnout among healthcare workers. A nationwide questionnaire-based survey was conducted from December 1, 2020, to January 29, 2021 on 1425 healthcare workers who worked in one of the 16 healthcare facilities designated for COVID-19 care, in public health centers, or as paramedics in Korea.

New established cell lines from undifferentiated pleomorphic sarcoma for in vivo study.

As a high-grade soft-tissue sarcoma (STS), undifferentiated pleomorphic sarcoma (UPS) is highly recurrent and malignant. UPS is categorized as a tumor of uncertain differentiation and has few options for treatment due to its lack of targetable genetic alterations. There are also few cell lines that provide a representative model for UPS, leading to a dearth of experimental research.

Evogliptin Directly Inhibits Inflammatory and Fibrotic Signaling in Isolated Liver Cells.

Chronic liver inflammation can lead to fibrosis, cirrhosis, and hepatocellular carcinoma. Kupffer cells (KC) secrete proinflammatory and fibrogenic cytokines in response to lipopolysaccharide (LPS), and so play an important role in liver inflammation, where they induce hepatocellular damage. LPS also activates hepatic stellate cells and induces extracellular matrix deposition.
