RESUMEN
Background/aim: Injury is an important public health problem in the pediatric age group and one of the leading global causes of morbidity and mortality. The fact that pediatric trauma has a significant impact on patients, families, and countries shows the need for a better understanding of this phenomenon. This study investigates the demographic characteristics, reasons for admission to the hospital, and diagnoses of pediatric trauma patients who received prehospital emergency health services. Materials and methods: This study was designed as a retrospective observational study and included all patients under the age of 18 who received emergency healthcare due to trauma and were registered in the Emergency Health Automation System after a call was placed to the emergency call center between 1 January 2018 and 31 December 2022. Information such as the reason for calling an ambulance, ICD-10 diagnosis codes, mechanism of injury, time of arrival at the scene, transport duration from the scene to the hospital, and reasons for interfacility transfers were collected for all patients. Results: A total of 37,420 patients were included in the analysis. Seventeen patients were found dead at the scene of the trauma and 35 patients experienced cardiac arrest on the way to the hospital from the scene. The difference between age groups in terms of time from arrival at the scene to arrival at the hospital was statistically significant (p < 0.001). Falls were the most common cause of trauma in all age groups, followed by traffic accidents. Patients requiring a specialist and transferred primarily for fall-related injuries were in direct proportion to the total number of cases (65.0%, n = 1838), followed by cases of traffic accidents and sports injuries. Most of the secondary transports were made to a training and research hospital or state hospital. Conclusion: Targeted preventive measures and community education should address the specific causes of trauma that are more prevalent in certain age groups. Early identification of special patient groups that typically require secondary transport can reduce mortality and morbidity related to trauma by facilitating direct transfers to appropriate hospitals.

Background and aim Stroke ranks among the primary contributors to disability and mortality on a global scale. Recent advances in ischemic stroke pathophysiology emphasize the significant role of the immune system in both stroke-related damage and neuroprotection. This article investigates the relationship between hemoglobin level and white blood cell count. Materials and methods From January 1, 2019, to April 1, 2022, all patients aged 18 years and over who were diagnosed with acute ischemic stroke in the emergency department of Kanuni Sultan Süleyman Training and Research Hospital and treated with intravenous recombinant tissue plasminogen activator (r-tPA) within 4.5 hours of stroke onset were included in this cross-sectional retrospective study. Gender, age, onset of symptoms, complaints, National Institutes of Health Stroke Scale (NIHSS) score, stroke-affected area, as well as leukocyte, neutrophil, platelet, eosinophil, lymphocyte, and hemoglobin levels were recorded and compared between mortality and survivor groups. Results A total of 61 people, including 33 men and 28 women, were included in the study. Four patients died during follow-ups. The mean duration of symptoms upon admission was 86.23 ± 56.37 minutes. The mean NIHSS score of patients was found to be 9.16 ± 3.88 (minimum: 4, maximum: 18). There was a statistically significant positive correlation between age and symptom duration (p < 0.002, r: 0.391). A statistically significant negative correlation was found between eosinophil count and NIHSS score (p < 0.012, r: -0.321) and between eosinophil count and symptom duration (p < 0.042, r: -0.261). There was a negative correlation between hemoglobin levels and mortality (p < 0.013, r: -0.318). A statistically significant negative correlation was observed between the eosinophil-to-neutrophil ratio (ENR) and NIHSS score (p < 0.017, r: -0.305) as well as between ENR and symptom duration (p < 0.034, r: -0.271). Hemoglobin is a significant predictor of mortality in the logistic regression model (p < 0.05, CI: 0.253-0.942). For each one-unit increase in hemoglobin, the odds of mortality decrease by a factor of 0.488. Conclusion Certain blood cell types (neutrophils, eosinophils, and lymphocytes) play an active role in determining stroke prognosis. A detailed explanation of the role of leukocyte types lays the foundation for "immunomodulation," which could be a promising novel treatment modality for future stroke patients.
RESUMEN
KEY POINTS: A moderate level of exercise has beneficial effects for the prevention of gastric ulcers. Although regular aerobic exercise was shown to elevate serum oxytocin levels and exogenously administered oxytocin exerts an anti-ulcer activity, the role of endogenous oxytocin in the gastroprotective effects of exercise has not yet been elucidated. We showed that increased anxiety and oxidative gastric damage induced by gastric ulcers were reversed in pre-exercised rats, while reduced hypothalamic oxytocin expression and decreased myenteric oxytocin receptor expression due to gastric ulcers were abolished by exercise. We also reported that the blockade of oxytocin receptors exaggerated gastric damage in exercised rats with ulcers. Our data establish that endogenous oxytocin is the key mediator in the beneficial effects of regular physical activity in alleviating gastric injury. ABSTRACT: Exercise increases serum oxytocin levels and exogenous oxytocin exerts an anti-ulcer activity; but the role of oxytocin in the protective effects of exercise against gastric ulcers has not yet been evaluated. This study was designed to investigate the impact of regular swimming exercise on oxidative gastric injury, and the role of oxytocin receptor activity in the anxiolytic and anti-inflammatory actions of exercise. Adult Wistar albino rats of both sexes performed swimming exercise (30 min/day, 5 days) or stayed sedentary. At the end of the 6-week exercise/sedentary protocol, rats were injected intraperitoneally with atosiban (0.1 mg/kg/day) or saline for 4 days. On the 5th day, under anaesthesia, acetic acid (ulcer) or saline (sham) was applied onto the gastric serosa and the treatments were continued. On the 9th day, anxiety levels were determined; gastric blood flow was measured, and blood, gastric and brain tissues were obtained. Induction of ulcers in sedentary rats increased anxiety and serum corticosterone levels; but reduced gastric blood flow and resulted in apoptosis and oxidative gastric damage with increased cytokine expressions. However, when ulcers were induced in pre-exercised rats, behavioural and biochemical alterations due to gastric damage were reversed. The inhibition of oxytocin receptors by atosiban exaggerated pro-inflammatory cytokine expressions and gastric lipid peroxidation in the stomachs of exercised rats with ulcers. When rats had regularly exercised prior to ulcer induction, reductions in the immunolabelling of hypothalamic oxytocin and myenteric oxytocin receptors were abolished, suggesting that exercise-induced alleviation of gastric injury may involve the reversal of down-regulated oxytocinergic activity.
