PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 129:155700. [PMID: 38704914 DOI: 10.1016/j.phymed.2024.155700] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Revised: 04/03/2024] [Accepted: 04/30/2024] [Indexed: 05/07/2024]
Abstract
BACKGROUND Myoglobin (Mb) induced death of renal tubular epithelial cells (RTECs) is a major pathological factor in crush syndrome-related acute kidney injury (CS-AKI). It is unclear whether ferroptosis is involved and could be a target for treatment. PURPOSE This study aimed to evaluate the potential therapeutic effects of combining the natural small molecule rosemarinic acid (RA) and the iron chelator deferasirox (Dfe) on CS-AKI through inhibition of ferroptosis. METHODS Sequencing data were downloaded from the GEO database, and differential expression analysis was performed using the R software limma package. The CS-AKI mouse model was constructed by squeezing the bilateral thighs of mice for 16 h with 1.5 kg weight. TCMK1 and NRK-52E cells were induced with 200 μM Mb and then treated with RA combined with Dfe (Dfe + RA, both were 10 μM). Functional and pathological changes in mouse kidney were evaluated by glomerular filtration rate (GFR) and HE pathology. Immunofluorescence assay was used to detect Mb levels in kidney tissues. The expression levels of ACSL4, GPX4, Keap1, and Nrf2 were analyzed by WB. RESULTS We found that AKI mice in the GSE44925 cohort highly expressed the ferroptosis markers ACSL4 and PTGS2. CS-AKI mice showed a rapid decrease in GFR, up-regulation of ACSL4 expression in kidney tissue, and down-regulation of GPX4 expression, indicating activation of the ferroptosis pathway. Mb was found to deposit in renal tubules, and it has been proven to cause ferroptosis in TCMK1 and NRK-52E cells in vitro. We found that Dfe had a strong iron ion scavenging effect and inhibited ACSL4 expression. RA could disrupt the interaction between Keap1 andNrf2, stabilize Nrf2, and promote its nuclear translocation, thereby exerting antioxidant effects. The combination of Dfe and RA effectively reversed Mb induced ferroptosis in RTECs. CONCLUSION In conclusion, we found that RA combined with Dfe attenuated CS-AKI by inhibiting Mb-induced ferroptosis in RTECs via activating the Nrf2/Keap1 pathway.

Abstract
Resuscitation of injured patients suffering from hemorrhagic shock with blood products in the prehospital environment is becoming more commonplace. However, blood product utilization is typically restricted and can be exhausted in the event of a prolonged entrapment. Delivery of large amounts of blood products to a scene is rare, particularly in rural settings. We present the case of a 26-year-old male who was entrapped in a motor vehicle for 144 min. First responders assessed the entrapped patient to be in hemorrhagic shock from lower extremities injuries. The Helicopter Emergency Medical Services team exhausted their supply of blood products shortly after arrival on scene. The local trauma center's Surgical Emergency Response Team (SERT) was requested to the scene. The preplanned response included seven units of blood components to provide massive transfusion at the point of injury and released directly to field responders by the blood bank. During extrication, the patient was given two units of packed red blood cells by initial responders with three more units of blood components from the SERT supply. During transfer to the hospital, the patient received an additional three units, and four units were transfused on initial trauma resuscitation in the hospital. He was found to have severe lower extremities injuries as the cause of his hemorrhage. The patient survived to hospital discharge. Delivery of large volumes of blood products to an entrapped patient with prolonged extrication time may be a lifesaving intervention. We advocate for integration of blood bank services and on scene physician guided resuscitation for prolonged extrications.

Abstract
INTRODUCTION Earthquakes rank among the most deadly natural disasters, and children are particularly affected due to their inherent vulnerability. Following an earthquake, there is a substantial increase in visits to emergency services. These visits stem not only from patients seeking care for physical traumas resulting from the earthquake and its subsequent complications, but also from individuals affected by the circumstances created by the disaster. STUDY OBJECTIVE This study aims to determine the characteristics and outcomes of children who presented to the pediatric emergency department (PED) after the earthquake and to evaluate children who had crush injuries at a referral tertiary university hospital away from the earthquake area. METHODS The medical records of children who presented to the PED from the earthquake area from February 6 through March 7, 2023 were retrospectively reviewed. Children rescued from under rubble were categorized as Group 1, those affected by earthquake conditions as Group 2, and patients seeking medical attention due to the follow-up of chronic illnesses were considered as Group 3. Patient data, including sociodemographic characteristics, time period under rubble (TPR), laboratory findings, and details of medical and surgical procedures, developing acute kidney injury (AKI), and the requirement for hemodialysis were recorded. RESULTS A total of 252 children were enrolled in the study, with 52 (20.6%) in Group 1, 180 (71.4%) in Group 2, and 16 (6.0%) in Group 3. The median age was six (IQR = 1.7-12.1) years. In the first group (n = 52), 46 (85.2%) children experienced crush injuries, 25 children (46.3%) developed crush syndrome, and 14 of them (14/25; 56.0%) required dialysis. In the second group, the most common diagnoses were upper respiratory tract infections (n = 69; 37.9%), acute gastroenteritis (n = 23; 12.6%), simple physical trauma (n = 16; 8.8%), and lower respiratory tract infections (n = 13; 7.1%). For children in the third group, pediatric neurology (n = 5; 33.3%), pediatric oncology (n = 4; 25.0%), and pediatric nephrology (n = 3; 18.8%) were the most frequently referred specialties. CONCLUSION Crush injuries, crush syndrome, and AKI were the most common problems in the early days following the earthquake. Along with these patients, children who were affected by the environmental conditions caused by the earthquake, as well as children with chronic illnesses, also accounted for a significant portion of visits to the PED, even if they were distant from the disaster area.

Medicine (Baltimore) 2024; 103:e37913. [PMID: 38640282 PMCID: PMC11029954 DOI: 10.1097/md.0000000000037913] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2024] [Revised: 03/21/2024] [Accepted: 03/25/2024] [Indexed: 04/21/2024] Open
Abstract
The aim of the study is to determine the usefulness of base excess (BE) and creatine kinase (CK) in predicting the extent of damage to the extremities, the need for hemodialysis, and the likelihood of mortality in crush injuries. Our study included patients who were affected by the earthquakes that occurred in Kahramanmaras/Turkey on February 6, 2023 and were diagnosed with crush injuries. The study was a retrospective observational study. We used chi-square test, independent sample t test, analysis of variance (ANOVA) to examine whether CK and BE values can be used to predict damage to the extremities, hemodialysis requirement, and mortality. A total of 299 patients were included in the study. A statistically significant relationship was found between BE and extremity damage, hemodialysis requirement, and mortality (P < .005). A statistically significant difference was also seen in terms of extremity damage and hemodialysis requirement with CK (P < .001), while there was no statistically significant difference seen in mortality (P = .204). BE may serve as a predictive biomarker for the development of extremities damage, hemodialysis requirement, and mortality. CK is not predictive of mortality.

Abstract
OBJECTIVE This study focuses on adults affected by the February 2023 Turkey earthquakes, aiming to uncover demographic and clinical traits. METHODS A retrospective analysis of data from adult patients who sought emergency care between February 6 and February 21, 2023, following the earthquakes, was conducted. RESULTS Among 3072 patients, 1544 (50.3%) of whom were women, trauma (31.1%) was the most prevalent cause of emergency department presentations. The median age of all patients was 44 y (interquartile range [IQR] 31-61 y). Hatay province accounted for 65.2% of trauma patients as origin. Most of the patients (66.8%) presented to the emergency department by their own means, while this was opposite for trauma patients, of whom 54.5% was transferred by means of Ambulance Service. Half of the total trauma patients were rescued from the debris, and 75.9% sustained limb injuries. Crush syndrome affected 24.7%, and emergency hemodialysis was performed on 9.1%, whereas emergency surgery was performed on 22.8% of all trauma cases. Overall, 10.2% of trauma patients lacked any identification. The rate of emergency department admittions due to respiratory and cardiovascular diseases was higher at the time of the earthquake compared with the previous year (P < 0.001). CONCLUSIONS The insights gained from this study hold valuable implications for disaster response strategies, emphasizing the importance of preparedness, timely intervention, and comprehensive patient care.

Abstract
Objective On 6 February 2023, 2 earthquakes with magnitudes of 7.7 and 7.6 mW occurred in Pazarcık and Elbistan districts of Kahramanmaraş province (Turkey) and affected 11 provinces in total, especially Hatay, Malatya, and Adıyaman. Here, we report 3 earthquake victims in order to define patients profiles. Case reports Three patients who were taken to the orthopedic and neurological rehabilitation program in our inpatient Physical Medicine and Rehabilitation unit after the earthquake are presented. Our first case, a 46-year-old man, remain-ed in the debris for 8.5 h. His left leg was left in the wreckage, and he later developed a drop foot on the left due to compartment syndrome, which developed with pain and swelling in the left calf. There is no fasciotomy procedure. Venous Doppler was reported to be within normal limits. Our second case is a 52-year-old man who was in the debris for 36 h and has a left braxial plexus injury and a left drop foot. He has Buerger's disease in his medical history. The third case is an 8-year-old girl trapped in rubble during the earthquake with a right orbital fracture and a left foot transmetarsal amputation. She has no neurological signs. Discussion The patients that apply to our Physical Medicine and Rehabilitation clinic are especially amputees, patients with traumatic brain injury, spinal cord injury, peripheral nerve damage, plexus damage, multiple fractures, joint limitations and soft tissue loss in the musculoskeletal system. After the earthquake, we encountered patients from a wide variety of spectrums in our clinic. In addition to primary musculoskeletal injuries, they also experience systemic problems affecting the musculoskeletal system. Additionally, thrombosis, infection, renal failure, and multiple organ failures may also occur. Conclusion Countries should develop guidelines for disaster preparedness and establish coordination units that can take quick action, make decisions, and communicate in times of disaster. A good definition of patient clinical profiles after the earthquake will ensure early intervention and prevent permanent disability and functional losses.

Abstract
Earthquakes are unpredictable natural disasters causing massive injuries. We aim to review the surgical management of earthquake musculoskeletal injuries and the critical care of crush syndrome. We searched the English literature in PubMed without time restriction to select relevant papers. Retrieved articles were critically appraised and summarized. Open wounds should be cleaned, debrided, receive antibiotics, receive tetanus toxoid unless vaccinated in the last 5 years, and re-debrided as needed. The lower limb affected 48.5% (21.9%-81.4%) of body regions/patients. Fractures occurred in 31.1% (11.3%-78%) of body regions/patients. The most common surgery was open reduction and internal fixation done in 21% (0%-76.6%), followed by plaster of Paris in 18.2% (2.3%-48.8%), and external fixation in 6.6% (1%-13%) of operations/patients. Open fractures should be treated with external fixation. Internal fixation should not be done until the wound becomes clean and the fractured bones are properly covered with skin, skin graft, or flap. Fasciotomies were done in 15% (2.8%-27.2%), while amputations were done in 3.7% (0.4%-11.5%) of body regions/patients. Principles of treating crush syndrome include: (1) administering proper intravenous fluids to maintain adequate urine output, (2) monitoring and managing hyperkalemia, and (3) considering renal replacement therapy in case of volume overload, severe hyperkalemia, severe acidemia, or severe uremia. Low-quality studies addressed indications for fasciotomy, amputation, and hyperbaric oxygen therapy. Prospective data collection on future medical management of earthquake injuries should be part of future disaster preparedness. We hope that this review will carry the essential knowledge needed for properly managing earthquake musculoskeletal injuries and crush syndrome in hospitalized patients.

Abstract
INTRODUCTION AND STUDY OBJECTIVE In Turkey, a total of 269 earthquakes took place from 1900 through 2023. The most devastating earthquakes in terms of casualties and extensive destruction occurred at 4:17am and 1:24pm local time on February 6, 2023 with the epicenters located in Pazarcik (Kahramanmaras) and Ekinozu (Kahramanmaras) and magnitudes of 7.7Mw and 7.6Mw, respectively. The aim of this study was to define the frequency of lung complications that occurred directly and/or developed during the intensive care follow-up of individuals affected by the Kahramanmaras earthquakes. METHOD A retrospective evaluation was conducted on the files of 69 patients who were rescued from the debris of collapsed buildings after the Kahramanmaras earthquakes and followed up in the intensive care unit in terms of the time under the debris, demographic data, vital signs, and lung complications that were present at the time of admission and developed during follow-up. SPSS for Windows v. 20.0 was used for data analysis. RESULTS The study included a total of 69 patients, of whom 29 (42%) were female and 40 (58%) were male. The mean age was 39.9 (SD = 16.9) years. The mean time under the debris was 53.9 (SD = 52) hours, and the mean time from rescue to the intensive care unit admission was 18.7 (SD = 12.8) hours. One or more pulmonary complications were detected in 52.2% (n = 36) of the patients at the time of admission. During the follow-up, 30.4% (n = 21) of the patients developed pulmonary congestion, 13.0% (n = 9) pneumonia, 1.5% (n = 1) alveolar hemorrhage, and 1.5% (n = 1) atelectasis, while no additional lung complications developed in the remaining 37 patients (53.6%). CONCLUSION Severe cases of individuals recovered from the debris can have a high prevalence of earthquake-related lung disorders and chest trauma, which may be associated with high mortality. The timely identification and effective intervention of pulmonary complications that may develop during follow-up can reduce mortality.

Abstract
Hyperbaric oxygen therapy (HBOT) has been used as an adjuvant treatment for crush injury because it can improve tissue hypoxia and stimulate wound healing. However, the actual role of HBOT in crush hand injury is still unknown. This study is to assess the efficacy of HBOT for crush hand patients, as well as the impact of HBOT initiation timing. Between 2018 and 2021, 72 patients with crush hand injury were retrospectively reviewed. The patients were divided into the HBOT and control group, and each group had 36 patients. The average session of HBOT was 18.2 (5-32 sessions) per patient, and no patient had a complication related to the treatment. The two groups had similar demographics, but HBOT group had larger injured area (73.6 ± 51.0 vs. 48.2 ± 45.5 cm2 , p = 0.03). To better control the confounding factors, we performed the subgroup analysis with cut-off injured area of 50 cm2 . In the patients with smaller injured area (≦50 cm2 ), the HBOT group had shorter wound healing time (29.9 ± 12.9 vs. 41.0 ± 18.9 days, p = 0.03). The early HBOT group (first session ≤72 h post-operatively) had shorter hospital stay (8.1 ± 6.4 vs. 15.5 ± 11.4 days, p = 0.04), faster wound healing (28.7 ± 17.8 vs. 41.1 ± 18.1 days, p = 0.08) and less operations (1.54 ± 0.78 vs. 2.41 ± 1.62, p = 0.06) although the latter two didn't achieve statistical significance. HBOT is safe and effective in improving wound healing of hand crush injury. Early intervention of HBOT may be more beneficial. Future research is required to provide more evidence.

Abstract
OBJECTIVE >50,000 people died in the February 2023 earthquakes in Türkiye. The aim of this study was to identify the factors affecting mortality rates of the trauma patients who were presented to the emergency department (ED) after the earthquake and provide suggestions for better preparedness strategies for future natural disasters. METHODS This retrospective, cross-sectional study encompassed data from 955 trauma patients out of 3072 patients aged 18 years and above who sought assistance in the ED. Patients were divided into two groups: the survivor group and the exitus group. Age, gender, the city where patients came from, type of presentation, injured organ systems and mechanisms of injury, laboratory findings, the diagnoses in the ED, time spent in the ED, surgical intervention, and hemodialysis sessions were analyzed. The characteristics of those who could not be identified at the presentation to the ED were subjected to additional analysis. RESULTS Out of 955 patients, 75.9% had extremity injuries, with crushing injuries (23.6%) being predominant. There were no significant differences in age or gender between the survivor and exitus groups (p = 0.776, p = 0.522), nor in the province of admission (p = 0.249). Clinical factors indicated that the exitus group were more likely to lack identification documents (29.6%), have spent longer trapped under debris, and have a higher frequency of ambulance transportation. Injuries such as chest and abdominal trauma, specific injury types, and amputation or open wounds were notably more frequent in the exitus group. Diagnoses revealed that metabolic causes were more common in exitus group (p < 0.001). While no significant difference existed in the need for emergency surgical intervention (p = 0.939), a higher frequency of emergency hemodialysis was observed among exitus group (p = 0.001). Laboratory findings indicated higher levels of various markers and lower calcium, base excess, and pH levels among those in the exitus group. CONCLUSION In the aftermath of a devastating earthquake, this study underscores the formidable challenges faced by healthcare systems during natural disasters. To prepare for future disasters, healthcare systems must enhance resilience, develop rapid identification techniques, and adopt a holistic patient care approach.

Abstract
BACKGROUND After the Kahramanmaras earthquake of February 6, 2023, the disaster of the century, a significant number of victims were admitted to intensive care units (ICUs). In this study, we aimed to share the characteristics and management of critical earthquake victims and shed light on our experiences as intensivists in future earthquakes. METHODS The study included 62 earthquake victims in two tertiary ICUs. Demographic characteristics, laboratory findings, clinical characteristics, trauma and disease severity scores, treatments administered to patients, and the clinical course of the patients were recorded retrospectively. The patients were divided into two groups, survivors and nonsurvivors, according to 7-day mortality and into two groups according to the duration of their stay under the rubble: those who remained under the rubble for 72 hours or less and those who remained under the rubble for more than 72 hours. A receiver operating characteristic (ROC) curve analysis was used to determine the best cutoff value for the 'Circulation, Respiration, Abdomen, Motor, and Speech' (CRAMS) score. RESULTS The median age of the 62 patients included in the study was 35.5 (23-53) years. The median length of stay under the rubble for the patients was 30.5 (12-64.5) hours. The patient was transferred to the ward with a maximum duration of 222 hours under the rubble. The limb (75.8%) was the most common location of trauma in patients admitted to the ICU. Crush syndrome developed in 96.8% of the patients. There was a positive correlation between the development of acute kidney injury (AKI) and myoglobin, serum lactate, and uric acid levels (r = 0.372, p = 0.003; r = 0.307, p = 0.016; r = 0.428, p = 0.001, respectively). The best cutoff of the CRAMS score to predict in-7-day mortality was < 4.5 with 0.94 area under the curve (AUC); application of this threshold resulted in 75% sensitivity and 96.3% specificity. CONCLUSION Search and rescue operations should continue for at least ten days after an earthquake. The CRAMS score can be used to assess trauma severity and predict mortality in critically ill earthquake victims.

J Transl Med 2023; 21:584.

Abstract
INTRODUCTION Disasters and accidents have occurred with increasing frequency in recent years. Primary disasters have the potential to result in mass casualty events involving crush syndrome (CS) and other serious injuries. Prehospital providers and emergency clinicians stand on the front lines of these patients' evaluation and treatment. However, the bulk of our current knowledge, derived from historical data, has remained unchanged for over ten years. In addition, no evidence-based treatment has been established to date. OBJECTIVE This narrative review aims to provide a focused overview of, and update on, CS for both prehospital providers and emergency clinicians. DISCUSSION CS is a severe systemic manifestation of trauma and ischemia involving soft tissue, principally skeletal muscle, due to prolonged crushing of tissues. Among earthquake survivors, the reported incidence of CS is 2-15%, and mortality is reported to be up to 48%. Patients with CS can develop cardiac failure, kidney dysfunction, shock, systemic inflammation, and sepsis. In addition, late presentations include life-threatening systemic effects such as hypovolemic shock, hyperkalemia, metabolic acidosis, and disseminated intravascular coagulation. Immediately beginning treatment is the single most important factor in reducing the mortality of disaster-situation CS. In order to reduce complications from CS, early, aggressive resuscitation is recommended in prehospital settings, ideally even before extrication. However, in large-scale natural disasters, it is difficult to diagnose CS, and to reach and start treatments such as continuous administration of massive amounts of fluid, diuresis, and hemodialysis, on time. This may lead to delayed diagnosis of, and high on-site mortality from, CS. To overcome these challenges, new diagnostic and therapeutic modalities in the CS animal model have recently been advanced. CONCLUSIONS Patient outcomes can be optimized by ensuring that prehospital providers and emergency clinicians maintain a comprehensive understanding of CS. The field is poised to undergo significant advances in coming years, given recent developments in what is considered possible both technologically and surgically; this only serves to further emphasize the importance of the field, and the need for ongoing research.
