RESUMEN

BACKGROUND: In natural disasters like earthquakes, building collapses can trap individuals, causing crush syndrome and rhabdomyolysis. This life-threatening condition often leads to acute kidney injury. We aimed to determine the effectiveness of the McMahon score in predicting mortality due to rhabdomyolysis in patients affected by the earthquake. METHODS: This is a retrospective observational study. In this study, the clinical and laboratory data of patients who presented to the emergency department due to the earthquake were analyzed. The McMahon score was calculated by evaluating factors such as creatine kinase, serum creatinine levels, age, and gender. RESULTS: The study included 151 patients, of whom 74 (49.0%) were male and 77 (51.0%) were female. In the univariate model, significant (P < .05) effectiveness was observed in differentiating between patients with and without mortality for McMahon score and the risk of acute kidney injury. At a McMahon score cutoff of 6, significant effectiveness was also observed, with an area under the curve of 0.723. At this cutoff value, the sensitivity was 80.0% and the specificity was 64.5%. CONCLUSIONS: The use of the McMahon score in emergency medicine and disaster management plays a crucial role in rapid decision-making processes due to its effectiveness in predicting mortality.

RESUMEN

BACKGROUND: During a major earthquake, escape attempts or collapsed buildings can result in injury, disability, and even death for victims. The aim of this study is to examine the demographic characteristics, clinical outcomes, and injuries of victims admitted to the emergency department within the first week after an earthquake. METHODS: This is a retrospective observational study conducted on earthquake victims who were admitted to the emergency services of a tertiary medical faculty and a training and research hospital in the city of Diyarbakir, located in the Southeastern Anatolia Region of Turkey, from February 6 through February 12, 2023. RESULTS: Of the eligible 662 earthquake victims, the mean age was 10.66 (SD = 4.78 [min 0, max 17]) in children, 36.87 (SD = 4.78 [min 18, max 63]) in adults, and 72.85 (SD = 5.83 [min 65, max 84]) in the elderly. Women constituted 52.8% of the victims, 19.7% were children, and 8.0% were elderly. Sixty-one percent (61.0%) of earthquake victims were admitted to emergency services in the first three days following the disaster; 37.7% of all victims were transferred from other affected cities to Diyarbakir. In all, 80.2% of the victims were admitted as survivors to the emergency services (36.8% were rescued under rubble, 40.1% with injuries while attempting to escape the earthquake, and 3.3% with nontraumatic reasons) and 19.8% were deceased under rubble. The majority of the 131 deceased victims were women (52.7%), 20.6% were children, and 7.6% were elderly. An estimated 38.3% of victims were hospitalized (20.9% in the ward and 17.4% in the intensive care unit [ICU]). For all age groups that survived under the rubble, the extremities were most injured (53.6% for children, 53.1% for adults, and 55.5% for the elderly). Of adult survivors, 26.6% needed only fluid therapy, renal replacement treatment (hemodialysis) was required 20.7%, and 11.8% required amputation. Of children survivors under the rubble, renal replacement treatment (hemodialysis) was required for only four, seven required amputation, and 12 needed only fluid resuscitation for crush injury. Of elderly survivors, two needed only fluid therapy, renal replacement treatment (hemodialysis) was required for two, and no amputation was required. Six patients survived under the rubble and died in the ICU. CONCLUSION: The definition of the demographic characteristics and clinical outcomes of earthquake patients is critical to the development of preparedness, response, and recovery policies for future disasters.

RESUMEN

SUMMARY: To investigate if the administration of boric acid (BA) would exert any protective effect against possible nephrotoxicity and hepatotoxicity induced by the exposure to acrylamide (ACR) in rats. In our study, we used a total of 28 rats that were divided into four equal groups. Group 1: the control group which was not treated with any procedure. Group 2: the ACR group that was administered ACR 50 mg/kg/day via intraperitoneal (i.p) route for 14 days. Group 3: the BA group that was administered BA 200 mg/kg/ day via gavage via peroral (p.o) route for 14 days. Group 4: the ACR+BA group that was administered BA simultaneously with ACR. Total antioxidant and oxidant (TAS/TOS) capacities were measured in all groups at the end of the experiment. In addition, the specimens obtained were evaluated with histopathological examination. Studies showed that the ACR and ACr+BA groups were not significantly different in terms of hepatic TAS level while the TOS level was higher in the ACR group than the ACR+BA group. The groups did not show any significant difference regarding renal TAS and TOS levels. In the histopathological examination of the hepatic tissue, the histopathological injury score of the ACR group was significantly higher than those of the other groups whereas it was significantly lower in the ACR+BA group than the ACR group. Our study concluded that Boric acid had a protective effect against acrylamide- induced hepatotoxicity, but not against nephrotoxicity.

El objetivo de este estudio fue investigar si la administración de ácido bórico (BA) ejercería algún efecto protector frente a la posible nefrotoxicidad y hepatotoxicidad inducida por la exposición a acrilamida (ACR) en ratas. En nuestro estudio, utilizamos un total de 28 ratas que se dividieron en cuatro grupos iguales. Grupo 1: grupo control que no fue tratado. Grupo 2: grupo ACR al que se le administró ACR 50 mg/kg/día por vía intraperitoneal (i.p) durante 14 días. Grupo 3: grupo BA al que se le administró BA 200 mg/kg/día por sonda por vía peroral (p.o) durante 14 días. Grupo 4: grupo ACR+BA al que se administró BA simultáneamente con ACR. Las capacidades antioxidantes y oxidantes totales (TAS/TOS) se midieron en todos los grupos al final del experimento. Además, los especímenes obtenidos fueron evaluados con examen histopatológico. Los estudios demostraron que los grupos ACR y ACr+BA no fueron significativamente diferentes en términos del nivel hepático de TAS, mientras que el nivel de TOS fue mayor en el grupo ACR que en el grupo ACR+BA. Los grupos no mostraron ninguna diferencia significativa con respecto a los niveles renales de TAS y TOS. En el examen histopatológico del tejido hepático, la puntuación de lesión histopatológica del grupo ACR fue significativamente mayor que la de los otros grupos, mientras que fue significativamente menor en el grupo ACR+BA que en el grupo ACR. Nuestro estudio concluyó que el ácido bórico tiene un efecto protector contra la hepatotoxicidad inducida por acrilamida, pero no contra la nefrotoxicidad.
