Purpose: Toy guns are popular among children but can pose serious risks of eye injury. This study analyzed toy gun-related ocular injuries (TGOIs) in pediatric patients over 20 years using the United States national data. Methods: A retrospective cross-sectional analysis was performed using the U.S. National Electronic Injury Surveillance System data from 2005 through 2024. We studied cases of pediatric patients presenting to emergency departments with TGOIs. Descriptive and comparative analyses were performed, and trends were analyzed across the study period, using chi-square test and analysis of variance. Results: A total of 695 pediatric cases of TGOI were identified, corresponding to an estimated 16,325 national cases in the U.S. Most injuries occurred in males (77.4%) and age of 7-12 years (54.0%). Common diagnoses included corneal abrasion (33.5%) and hyphema (22.2%), with severe cases also reported such as ruptured globe (1.0%) and corneal laceration (0.3%). Injuries were most frequent during winter (32.1%). Over the study period, there were increases in mean age (from 8.9 years [2005-2009] to 9.6 years [2020-2024]), overall reported number of cases (from 47 to 341), and diagnosis of hyphema (from 8.5% to 25.2%). Conclusions Pediatric TGOI is increasing in frequency, with shifting demographic and clinical patterns. These findings highlight the urgent need for enhanced safety regulations and public health interventions to prevent vision-threatening trauma in children.

BACKGROUND/OBJECTIVES: Mitigating insulin resistance and hyperglycemia is associated with a decreased risk of diabetic complications. The effect of Daraesoon (shoot of hardy kiwi, Actinidia arguta) on hyperglycemia was investigated using a type 2 diabetes animal model.MATERIALS/METHODS: Seven-week-old db/db mice were fed either an AIN-93G diet or a diet containing 0.4% of a 70% ethanol extract of Daraesoon, whereas db/+ mice were fed the AIN-93G diet for 7 weeks. RESULTS: Consumption of Daraesoon significantly reduced serum glucose and blood glycated hemoglobin levels, along with homeostasis model assessment for insulin resistance in db/db mice. Conversely, Daraesoon elevated the serum adiponectin levels compared to the db/db control group. Furthermore, Daraesoon significantly decreased both serum and hepatic triglyceride levels, as well as serum total cholesterol levels. Additionally, consumption of Daraesoon resulted in decreased hepatic tumor necrosis factor-α and monocyte chemoattractant protein-1 expression. CONCLUSIONS These results suggest that hypoglycemic effect of Daraesoon is mediated through the improvement of insulin resistance and the downregulation of pro-inflammatory cytokine expression in db/db mice

BACKGROUND/OBJECTIVES: The prevalence of obesity, a worldwide pandemic, has been increasing steadily in Korea. Reports have shown that increased intermuscular adipose tissue (IMAT) is associated with an increased risk of cardiovascular disease, independent of body mass index. However, the relationship between dietary intake and IMAT accumulation in the Korean population remains undetermined. The objective of this study was to evaluate regional fat compartments using advanced magnetic resonance imaging (MRI) techniques. We also aimed to investigate the association between IMAT amounts and dietary intake, including carbohydrate intake, among Korean individuals with obesity. SUBJECTS/METHODS: This cross-sectional study, performed at a medical center in South Korea, recruited 35 individuals with obesity (15 men and 20 women) and classified them into 2 groups according to sex. Anthropometry was performed, and body fat distribution was measured using MRI. Blood parameters, including glucose and lipid profiles, were analyzed using commercial kits. Linear regression analysis was used to test whether the IMAT was associated with daily carbohydrate intake. RESULTS: Carbohydrate intake was positively associated with IMAT in all individuals, with adjustments for age, sex, height, and weight. No significant differences in blood indicators were found between the sexes. CONCLUSIONS Regardless of sex and age, higher carbohydrate intake was strongly correlated with greater IMAT accumulation. This suggests the need to better understand sex differences and high carbohydrate diet patterns in relation to the association between obesity and metabolic risk, which may help reduce obesity prevalence.

Purpose: : This study aimed to determine the effectiveness of end-of-life care debriefing as an intervention to reduce moral distress among intensive care unit (ICU) nurses after end-of-life care. Methods: : This quasiexperimental study included 104 nurses (46 in the control group and 58 in the intervention group) working in three medical ICUs and two surgical ICUs. The data collection period was from September 1, 2017, to January 31, 2018, and end-of-life care debriefing in the intervention group was implemented over three months. Debriefings were conducted in groups or individually, with eight people participating in three or more debriefings. Comparisons of end-of-life care stress, end-of-life care attitudes, and wellness between the two groups were performed using an ANCOVA. Satisfaction with the debriefing was analyzed using descriptive statistics. Results: : End-of-life care stress and wellness did not differ between the groups, but there was a significant difference in end-of-life care attitudes. Overall, 50% of the participants were satisfied with the debriefing. Conclusion : Based on the finding that end-of-life care debriefing has a positive impact on ICU nurses’ attitudes toward end-of-life care, it can be used as an effective measure to reduce nurses’ moral distress. An institutional debriefing system should be established and operationalized.

Purpose: Type 2 diabetes mellitus is a metabolic condition marked by persistent elevated blood sugar levels resulting from insulin resistance. The effective management of diabetes mellitus involves strict regulation of the blood glucose levels. This study examined the effects of Autumn olive (Elaeagnus umbellata Thunb.) berry (AOB) on insulin resistance and hyperglycemia using a type 2 diabetes mellitus animal model. Methods: Eight-week-old C57BL/6J mice were divided into four groups. The control group received a basal diet, while the high-fat, high-sucrose (HFHS) group was fed a HFHS diet containing 27% sucrose and 33% lard for 12 weeks. The low AOB (LAOB) and high AOB (HAOB) groups were offered a HFHS diet with a 0.5% and 1.0% AOB extract, respectively. Results: The HAOB group showed significantly lower epididymal fat pad weight than the HFHS group. The LAOB and HAOB groups showed lower serum glucose levels and homeostasis model assessment for insulin resistance values than the HFHS group, and the HAOB group has lower serum insulin levels than the HFHS group. Supplementation with HAOB decreased serum cholesterol levels significantly compared with the HFHS group. The consumption of LAOB and HAOB reduced the serum triglyceride and hepatic total lipids and triglyceride levels compared to the HFHS group. In addition, LAOB and HAOB consumption in mice fed a HFHS diet increased adenosine monophosphate-activated protein kinase protein expression. Insulin receptor substrate-2 protein expression in the HAOB group was significantly higher than the HFHS group. Conclusion AOB can alleviate hyperglycemia in type 2 diabetes mellitus partly by mitigating insulin resistance.

Acute ascending hemorrhagic longitudinally extensive transverse myelitis is a rare inflammatory demyelinating disorder, which invades several vertebral segments and progresses rapidly and manifests severe symptoms. We present a case of acute necrotizing myelitis associated with COVID-19 infection. A 10-year-old female, with no previous medical history and no prior administration of COVID-19 vaccination, contracted COVID-19 in early April 2022. Two weeks later, she suffered from severe posterior neck pain and also presented with motor weakness and numbness in both lower extremities, making it difficult to walk independently and spontaneously void urine. Initial spinal cord MR showed longitudinally segmental extensive T2 hyperintensities. Cerebrospinal fluid (CSF) analysis revealed elevated red blood cell, normal white blood cell, and elevated protein levels and absence of oligoclonal bands. CSF culture and viral polymerase chain reaction were negative. Autoimmune work-up was negative. She was started on intravenous methylprednisolone 1g/day for 5 days and immunoglobulin (Ig) 2 g/kg for 5 days. She was also treated with six courses of therapeutic plasma exchange. Nevertheless, her pain and motor weakness persisted. She eventually developed respiratory failure. Follow-up MR presented a newly noted small hemorrhagic component. She was consequently treated with two additional courses of methylprednisolone and Ig. At 6-months follow-up, neurological examination showed improvement with normal sensory function and motor grade IV function in both upper extremities. We present the case of acute necrotizing myelitis associated with COVID-19 infection. Multiple courses of methylprednisolone and Ig showed mild improvement in motor and sensory function. However, poor prognosis was unavoidable due to rapid progression of the disease.

This review explores the potential benefits of taurine in ameliorating the metabolic disorders of obesity and type 2 diabetes (T2D), highlighting the factors that bridge these associations. Relevant articles and studies were reviewed to conduct a comprehensive analysis of the relationship between obesity and the development of T2D and the effect of taurine on those conditions. The loss of normal β-cell function and development of T2D are associated with obesity-derived insulin resistance. The occurrence of diabetes has been linked to the low bioavailability of taurine, which plays critical roles in normal β-cell function, anti-oxidation, and anti-inflammation. The relationships among obesity, insulin resistance, β-cell dysfunction, and T2D are complex and intertwined. Taurine may play a role in ameliorating these metabolic disorders through different pathways, but further research is needed to fully understand its effects and potential as a therapeutic intervention.
