Objectives:
Benzene, toluene, ethylbenzene, and xylenes (BTEX) are co-occurring neurotoxicants that are structurally similar aromatic hydrocarbons sharing common metabolic pathways and mechanisms of toxicity. This study investigated the effects of BTEX exposure on depression and aimed to identify the primary contributors to depression risk.
Methods:
We conducted a cross-sectional analysis of 1733 adults from the 2020–2021 Korea National Health and Nutrition Examination Survey. BTEX exposure was quantified based on urinary metabolite concentrations: S-phenylmercapturic acid (SPMA) for benzene, benzylmercapturic acid for toluene, the sum of phenylglyoxylic acid and mandelic acid for ethylbenzene, and methylhippuric acid for xylenes. Depression was defined according to self-reported physician diagnosis. Logistic regression was used to estimate the risk associated with individual chemicals, while weighted quantile sum (WQS) regression was employed to assess mixture effects and identify the primary toxicant. Sensitivity analyses were performed to address potential confounding by tobacco smoke.
Results:
Urinary SPMA concentrations were significantly higher in individuals with depression. Logistic regression revealed a significant association between SPMA levels and depression (odds ratio, 2.62; 95% confidence interval, 1.34 to 5.13). Although the overall BTEX mixture was not significantly associated with depression after covariate adjustment in WQS models, SPMA consistently emerged as the major contributor. The association between SPMA and depression remained robust in sensitivity analyses excluding participants exposed to tobacco smoke.
Conclusions
Benzene exposure was associated with an increased risk of depression in the general Korean adult population. Therefore, strengthened environmental regulations on benzene could help reduce the public health burden of depression.

Olanzapine is a second-generation antipsychotic drug associated with the development of type 2 diabetes. However, the development and remission of diabetes with glutamic acid decarboxylase (GAD) antibody (Ab) positivity related to olanzapine treatment have not been reported. Here, we present the case of a 33-year-old man taking olanzapine who was diagnosed with diabetes with GAD Ab positivity complicated by diabetic ketoacidosis (DKA). After discontinuation of the drug and tight glycemic control, his diabetes remitted, and the GAD Ab became negative spontaneously after 18 months. The classification of diabetes is challenging because of overlapping autoimmune and metabolic features. Olanzapine may have contributed to pancreatic β-cell apoptosis, which could potentially trigger autoimmunity and the development of type 1 diabetes-like features (DKA as the initial presentation, a low C-peptide level, and GAD Ab positivity). The rapid amelioration of hyperglycemia and weight reduction may be responsible for the remission of diabetes after the discontinuation of olanzapine.

Child Health Nursing Research 2025;31(1):4-14
Purpose:
Nurses play a crucial role in cases of victims of child abuse; however, but there is a need for a comprehensive understanding of their specific roles, responsibilities, and best practices is needed.
Methods:
This integrative review aims to synthesize existing evidence on the role of nurses in cases of victims of child abuse. A literature search was conducted using PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, and Scopus databases. A literature search was conducted using PubMed, CINAHL, PsycINFO, and Scopus databases. This review included 12 qualitative and quantitative studies. Results: This review identified the following four themes: nurses’ responsibility, intention to report child abuse, perceptions of child abuse, and risk assessment of child abuse. The findings revealed that nurses play a multifaceted role in child abuse situations. Evidence-based practices and guidelines were identified to optimize recovery outcomes among children who have experienced abuse.
Conclusion
This integrative review contributes to the body of knowledge on nurses’ role in cases of victims of child abuse by providing valuable insights for nursing practice, education, and policy. These findings can help guide nurses in developing evidence-based interventions and collaborative approaches to support the recovery of victims of child abuse.

Background:
Children, adolescents, and young adults (CAYAs) with severe illnesses require intensive treatment, often relying on medical devices and advanced medical services.Modern medical technology has improved the lifespans of these patients. In addition, CAYAs represent a vulnerable group, resulting in a significant caregiving burden on the entire family.This study examined patterns of medical utilization following diagnosis of a life-limiting condition (LLC).
Methods:
We establish a cohort of 176,236 CAYAs who were first diagnosed with an LLC using National Health Insurance data between 2011 and 2013. Patients diagnosed with an LLC within the 3 years preceding this period and those who had died were excluded, and only those receiving care at a general medical hospital were included. In total, 25,410,411 claims for medical expenses, outpatient visits, and lengths of stay for medical utilization over the approximately 10 years up to 2020 were investigated (2.3% inpatients, 97.7% outpatients).
Results:
The average annual medical utilization per LLC patient among CAYAs following initial diagnosis included medical expenses of $1,163, 16.8 outpatient visits, and 18.7 days of admission. Among inpatients, cancer patients averaged $5,340 for total medical expenses and 21.0 days of admission, while non-cancer patients averaged $3,013 and 18.1 days, respectively. The overall average medical expenses during the first year following diagnosis of an LLC were $3,012, whereas for cancer patients they were $5,962. In addition, there was a sharp increase in total medical expenses as death approached, particularly in the last month of life, with a considerable proportion attributable to critical-care treatments.
Conclusion
Our investigation into medical utilization by CAYAs with an LLC in Korea provides a foundation for healthcare policy development. Timely treatment at each stage and tailored policies that take into account the heterogeneity among diseases are of paramount importance.

Annals of Clinical Nutrition and Metabolism 2024;16(3):89-111
Purpose:
Nutritional support for adult critically ill patients is essential due to the high risk of malnutrition, which can lead to severe complications. This paper aims to develop evidence-based guidelines to optimize nutritional support in intensive care units (ICUs).
Methods:
The Grading Recommendations, Assessment, Development and Evaluation process was used to develop and summarize the evidence on which the recommendations were based. Clinical outcomes were assessed for seven key questions.
Results:
We recommend the following: (1) initiate enteral nutrition (EN) within 48 hours after treatment as it is associated with improved outcomes, including reduced infection rates and shorter ICU stays; (2) early EN is preferred over early parenteral nutrition due to better clinical outcomes; (3) the use of supplementary parenteral nutrition to meet energy targets during the first week of ICU admission in patients receiving early EN is conditionally recommended based on patient-specific needs; (4) limited caloric support should be supplied to prevent overfeeding and related complications, particularly in the early phase of critical illness; (5) higher protein intake is suggested to improve clinical outcomes, such as muscle preservation and overall recovery; (6) additional enteral or parenteral glutamine is conditionally recommended against due to the lack of significant benefit and potential harm; and (7) fish oil-containing lipid emulsions is conditionally recommended due to their potential to enhance clinical outcomes, including reduced infection rates and shorter ICU stays.
Conclusion
These evidence-based recommendations can improve clinical outcomes and support healthcare providers in making informed decisions about nutritional interventions in the ICU.
