Comparison of emergency medicine specialist, cardiologist, and chat-GPT in electrocardiography assessment.

INTRODUCTION: ChatGPT, developed by OpenAI, represents the cutting-edge in its field with its latest model, GPT-4. Extensive research is currently being conducted in various domains, including cardiovascular diseases, using ChatGPT. Nevertheless, there is a lack of studies addressing the proficiency of GPT-4 in diagnosing conditions based on Electrocardiography (ECG) data. The goal of this study is to evaluate the diagnostic accuracy of GPT-4 when provided with ECG data, and to compare its performance with that of emergency medicine specialists and cardiologists. METHODS: This study has received approval from the Clinical Research Ethics Committee of Hitit University Medical Faculty on August 21, 2023 (decision no: 2023-91). Drawing on cases from the "150 ECG Cases" book, a total of 40 ECG cases were crafted into multiple-choice questions (comprising 20 everyday and 20 more challenging ECG questions). The participant pool included 12 emergency medicine specialists and 12 cardiology specialists. GPT-4 was administered the questions in a total of 12 separate sessions. The responses from the cardiology physicians, emergency medicine physicians, and GPT-4 were evaluated separately for each of the three groups. RESULTS: In the everyday ECG questions, GPT-4 demonstrated superior performance compared to both the emergency medicine specialists and the cardiology specialists (p < 0.001, p = 0.001). In the more challenging ECG questions, while Chat-GPT outperformed the emergency medicine specialists (p < 0.001), no significant statistical difference was found between Chat-GPT and the cardiology specialists (p = 0.190). Upon examining the accuracy of the total ECG questions, Chat-GPT was found to be more successful compared to both the Emergency Medicine Specialists and the cardiologists (p < 0.001, p = 0.001). CONCLUSION: Our study has shown that GPT-4 is more successful than emergency medicine specialists in evaluating both everyday and more challenging ECG questions. It performed better compared to cardiologists on everyday questions, but its performance aligned closely with that of the cardiologists as the difficulty of the questions increased.

Inferior vena cava collapsibility index and stroke volume as predictors of blood transfusion in upper gastrointestinal bleeding in the emergency department.

BACKGROUND AND AIM: This study investigates the effectiveness of bedside ultrasonography in predicting blood transfusion requirements in patients with upper gastrointestinal bleeding (UGIB). It focuses on evaluating the inferior vena cava (IVC) diameter, IVC collapsibility index (CI), and stroke volume (SV) as ultrasonographic measures. METHODS: A hundred adult patients enrolled in this prospective clinical study. The patients were divided into two groups (group 1: only saline administered group, group 2: saline and blood administered group). IVC diameter, IVC CI, and SV were measured at the time of admission and after treatment. RESULTS: At the initial admission, group 1 exhibited an IVC CI of 20.4% and an SV of 65.0 mL, whereas group 2 displayed an IVC CI of 26.6% and an SV of 58.0 mL. Upon analyzing the relationship between the Glasgow-Blatchford score (GBS) and SV, we identified a significant negative correlation (r = -0.7350; P < 0.001). Similarly, a weak negative correlation was observed between the Rockall score (RS) and SV (r = -0.4718; P < 0.001). It is worth noting that patients with UGIB require blood transfusion if their SV falls below 62.5 mL, with an area under the curve (AUC) of 89.1% and a 95% confidence interval (CI) ranging from 82.8% to 95.4%. CONCLUSION: IVC CI and SV can be used as parameters to predict the need for blood transfusion in the ED in patients with UGIB.

Investigation of highly cited publications related to vaccines against COVID-19: current state and future predictions.

BACKGROUND: Since the date of declaring the COVID-19 outbreak a pandemic by the World Health Organization (March 11, 2020), vaccine studies have been initiated. In this article, we aimed to investigate highly cited articles on vaccines and guide researchers for future studies. MATERIAL AND METHODS: Publications with 6 or more citations (highly cited publications) were extracted from Web of Science (WoS) database. These publications were investigated according to the number of citations, language, publication year, WoS categories, publication types, organizations involved, authors, countries and research areas. Additionally, top 20 articles were investigated in detail. RESULTS: A total of 126 publications were determined. When WoS categories were investigated, 18 pertained to immunology (14.2 %), 17 to biochemistry (13.4 %) and 17 to multidisciplinary sciences (13.4 %). There were three types of publications, namely 80 original articles (63.4 %), 46 reviews (36.5 %) and 11 early access publications (8.7 %). Top universities were Harvard University (n=9, 7.1 %), Chinese Academy of Medical Sciences (n=7, 5.5 %) and University of California system (n=7, 5.5 %). Top authors were Qin CF with 4 articles (3.1 %), Wang L with 4 articles (3.1 %) and Baric RS with 3 articles (2.3 %). Top journals with the highest number of publications were Journal of Biomolecular Structure Dynamics (n=8, 6.3 %), Nature (n=8, 6.3 %) and Science (n=6, 4.7 %). Top countries were the United States of America (USA) with 45 articles (35.7 %), People's Republic of China with 44 articles (34.9 %), and India with 15 articles (11.9 %). Research areas of the publications were science technology other topics (n=21, 16.6 %), immunology (n=18, 14.2 %) and pharmacology (n=18, 14.2 %). CONCLUSION: Vaccine studies play a pivotal role in the warfare against COVID-19. Our results revealed that under the leadership of the USA, China and India, the number of scientists focusing on vaccines is increasing and gratifying results are obtained from vaccine studies (Tab. 3, Ref. 40).

Comparison of performances of top emergency medicine journals in terms of COVID-19 publications in 2020.

INTRODUCTION: The aim of this study is to evaluate the qualitative and quantitative contribution of Emergency Medicine (EM) journals to scientific literature on COVID-19 and compare the journals in terms of publications. MATERIAL AND METHODS: We performed a comparison of top EM journals by hand-search in terms of COVID-19 publications and citations between January 1st and December 31st, 2020. Publications were also categorized according to research field, country and article types. Data were given as numbers and percentages. RESULTS: Among 18 EM journals, Resuscitation ranked in the first place and American Journal of Emergency Medicine ranked in the last place according to Impact Factor. In these journals, 512 (12.2%) articles related to COVID-19 were published. The American Journal of Emergency Medicine and Internal and Emergency Medicine published the greatest amount of publications related to COVID-19 (n = 71). The American Journal of Emergency Medicine was also the leading journal in terms of "Total Citations to COVID-19 Articles" (n = 1192). Western Journal of Emergency Medicine published the greatest proportion of COVID-19 articles (Total COVID-19 Articles/Total Articles = 0.3). World Journal of Emergency Surgery ranked in the first place in terms of citations per COVID-19 articles (n = 33.2). The most common studied field was Effects of COVID-19 on the Health System (n = 222). The US was the most productive country with 188 COVID-19 publications and 1411 citations to these publications, followed by Italy. CONCLUSION: The contribution of EM journals to COVID-19 literature is controversial. "Effects of COVID-19 on the Health System" is the most studied field. "Clinical Properties, Ethical Issues and Treatment Methods" are neglected fields in EM journals.

Interleukin-33 (IL-33) as a Diagnostic and Prognostic Factor in Traumatic Brain Injury.

Interleukin-33 (IL-33) is a cytokine involved in interleukin-1 family. Role of IL-33 in immune system activation is well described in the literature. IL-33 has been identified as an endogenous alarm signal (alarmin) to alert various types of immune cells to trauma. In this narrative review, we aimed to underline the diagnostic and prognostic importance of IL-33 in trauma, particularly in brain trauma.

Analysis of Road Traffic Accidents in Turkey between 2013 and 2017.

Introduction: Road traffic accident (RTAs) is one of the top ten leading causes of death worldwide and its incidence is higher in developing countries. In this study, our aim was to determine the characteristics of RTAs in Turkey and make recommendations to reduce mortality and morbidity related to RTAs. Material and Methods: We obtained our data, which cover the years 2013 to 2017, from the database accessible at the official website of the Turkish Statistical Institute, which permits the use of its data for research purposes. The chi-square test was used for statistical analysis, and the percentage distribution and odds ratios were calculated. Results: In the study period, a total of 697,957 RTAs occurred in Turkey. A total of 1,168,121 individuals have been wounded and 3534 of them have lost their lives. The majority of RTAs occurred on weekends and in summer months. Male individuals are more likely to be exposed to death and injuries related to accidents. When the vehicle type is considered, motorcycle drivers are under more risk for RTAs. RTAs are more likely to occur in rural areas. Conclusion: Male individuals and motorcyclists are under a great risk for RTAs. Strict laws are mandatory in order to reduce morbidity and mortality related to RTAs. Additionally, educational efforts must focus on two-wheelers and tractor drivers, particularly in developing countries.

Report of a rare case of severe allergic reaction due to nasal myiasis and a brief review of the literature in Turkey.

Myiasis is defined as infestation of a mammal by fly larvae. It may occur on either living tissues (primary myiasis) or dead tissues (secondary myiasis). In this report, we present a patient with myiasis with an extremely rare clinical manifestation and severe allergic reaction, and we review the literature in order to reveal the current status. A 20-year-old female patient was admitted to our emergency department due to rush on face, cough and shortness of breath. The maggot came out of her nose was identified as Oestrus ovis. With a diagnosis of severe allergic reaction due to myiasis, she was treated diphenhidramine, prednisone and inhale albuterol in the emergency department. After treatment and further investigation, she was discharged with full recovery. Myiasis is a rare cause for severe allergic reaction in patients with definite diagnosis. Immediate diagnosis and treatment are milestones in preventing bad outcomes.

How Prepared Are We for Possible Bioterrorist Attacks: An Approach from Emergency Medicine Perspective.

Preparedness for bioterrorist attacks and early recognition of specific agents are essential for public health. Emergency departments may play an important role in this field. The large spectrum of bioterrorism involves not only disastrous terrorism with mass casualties, but also microevents using low technology but producing civil unrest, disruption, disease, disabilities, and death. It aims not only to cause mortality and morbidity, but also to lead to social and political disruption. Preparedness appears to be the most potent defense against possible bioterrorist events. In this article, we aim to create awareness against biological agents and underline the importance of emergency departments in this public health problem.

Investigation of Geriatric Patients with Abdominal Pain Admitted to Emergency Department.

INTRODUCTION: The aim of this study is to detect the possible reasons of abdominal pain in the patients aged 65 and older admitted to emergency department (ED) with complaint of abdominal pain which is not related to trauma, to determine the length of hospitalization of old (65-75 age) and elderly (aged 75 and older) patients, and to define the hospitalization and mortality rates. MATERIAL AND METHODS: In the study, 336 patients were included. Groups were compared in respect to gender, internal or surgical prediagnoses, complaints accompanying abdominal pain, vital findings, comorbidities, requested consultations, hospitalizing service, waiting time in the ED and in the hospital, and treatment methods. RESULTS: Of the patients, 48.2% were male, and 51.8% were female. While 52.4% of the patients were in 65-74 age group, 47.6% of them were aged 75 years and above. An internal disease was detected in 76.8% of the patients as an origin of abdominal pain. Most common prediagnoses were biliary diseases and diseases related to biliary tract followed by nonspecific abdominal pain, abdominal pain secondary to malignity, ileus, and acute gastroenteritis, respectively. The most frequent finding accompanying abdominal pain was vomiting. The most frequent chronic disease accompanying abdominal pain was hypertension in both age groups. We observed that 75.9% of the patients required consultation. We detected that 48.8% of the patients with abdominal pain were hospitalized and they were hospitalized mostly by gastroenterology ward (24.8%). Surgical treatments were applied to the 17.6% of the patients with abdominal pain. CONCLUSION: Clinical findings become indistinct by age, and differential diagnosis of abdominal pain gets more difficult in geriatric patients. Therefore, physicians should consider age related physiological changes in order to distinguish geriatric patients admitted to emergency service with abdominal pain from pathological cases requiring immediate surgical operation.

Bacterial and protozoal pathogens found in ticks collected from humans in Corum province of Turkey.

BACKGROUND: Tick-borne diseases are increasing all over the word, including Turkey. The aim of this study was to determine the bacterial and protozoan vector-borne pathogens in ticks infesting humans in the Corum province of Turkey. METHODOLOGY/PRINCIPAL FINDINGS: From March to November 2014 a total of 322 ticks were collected from patients who attended the local hospitals with tick bites. Ticks were screened by real time-PCR and PCR, and obtained amplicons were sequenced. The dedected tick was belonging to the genus Hyalomma, Haemaphysalis, Rhipicephalus, Dermacentor and Ixodes. A total of 17 microorganism species were identified in ticks. The most prevalent Rickettsia spp. were: R. aeschlimannii (19.5%), R. slovaca (4.5%), R. raoultii (2.2%), R. hoogstraalii (1.9%), R. sibirica subsp. mongolitimonae (1.2%), R. monacensis (0.31%), and Rickettsia spp. (1.2%). In addition, the following pathogens were identified: Borrelia afzelii (0.31%), Anaplasma spp. (0.31%), Ehrlichia spp. (0.93%), Babesia microti (0.93%), Babesia ovis (0.31%), Babesia occultans (3.4%), Theileria spp. (1.6%), Hepatozoon felis (0.31%), Hepatozoon canis (0.31%), and Hemolivia mauritanica (2.1%). All samples were negative for Francisella tularensis, Coxiella burnetii, Bartonella spp., Toxoplasma gondii and Leishmania spp. CONCLUSIONS/SIGNIFICANCE: Ticks in Corum carry a large variety of human and zoonotic pathogens that were detected not only in known vectors, but showed a wider vector diversity. There is an increase in the prevalence of ticks infected with the spotted fever group and lymphangitis-associated rickettsiosis, while Ehrlichia spp. and Anaplasma spp. were reported for the first time from this region. B. microti was detected for the first time in Hyalomma marginatum infesting humans. The detection of B. occultans, B. ovis, Hepatozoon spp., Theileria spp. and Hemolivia mauritanica indicate the importance of these ticks as vectors of pathogens of veterinary importance, therefore patients with a tick infestation should be followed for a variety of pathogens with medical importance.

Investigation of mindin levels in hypertensive patients with left ventricular hypertrophy and QRS fragmentation on electrocardiography.

PURPOSE: Mindin was associated with diabetic nephropathy, podocyte injury, colitis, allergic asthma, liver ischaemia and reperpusion injury and ischaemic brain injury. On the other hand, it was reported as a protective factor against obesity, cardiac hypertrophy, fibrosis and remodelling. Fragmented QRS complexes (fQRS) are markers of altered ventricular depolarisation owing to a prior myocardial scar and fibrosis. In this study, we aimed to investigate mindin levels in hypertensive patients with left ventricular hypertrophy and fQRS on electrocardiography. METHODS: This observational case-control study enrolled 70 (36 female) hypertensive patients with fQRS and 38 (23 female) hypertensive control patients. All patients were evaluated by transthoracic echocardiography. Mindin levels were measured by the enzyme-linked immunosorbent assay (ELISA). Clinical, echocardiographic and laboratory data were compared between patient and control groups. RESULTS: There was no significant difference between patient and control groups in terms of clinical, echocardiographic and routine laboratory parameters. The mindin levels were significantly higher in the patient group than controls (11.3 (7.21-19.31) vs 4.15 (2.86-6.34); p < .001). Multiple logistic regression analyses defined increased mindin levels as an independent predictor for the presence of fQRS (Odds ratio: 1.733; p = .034). Mindin levels >6.74 predicted the presence of fQRS with a sensitifity of 84.3% and specificity of 79.9% on receiver operating characteristic (ROC) curve analysis (The area under the curve:0.889; Confidence Interval: 0.827-0.951; p < .001). CONCLUSION: Mindin expressin is upregulated in hypertensive patients with fQRS complexes. In contrary to previous studies, increased mindin levels may be associated with myocardial fibrosis.

Acute ischemic stroke and severe multiorgan dysfunction due to multiple bee stings.

Various manifestations after bee sting have been described. Local reactions, such as pain, wheal, flare, edema and swelling, are common and generally self-limiting. Uncommonly manifestations like vomiting, diarrhea, dyspnea, generalized edema, acute renal failure, anaphylactic shock, myocardial infarction, hypotension, collapse, pulmonary hemorrhage, acute hemorrhagic pancreatitis, and atrial fibrillation may occur. We report a 59 year-old man who sustained ischemic stroke and multi-organ dysfunction following multiple bee stings.

Investigation of Toxic Effects of Mushroom Poisoning on the Cardiovascular System.

Mushroom poisoning (MP) is a public health problem in many countries. It is well known that consumption of wild mushrooms may cause serious toxicity on renal, hepatic and brain functions. In the literature, however, studies investigating cardiotoxic effects of MP are rare. In this study, we evaluated laboratory and ECG findings of patients and sought for possible toxic effects of MP on the cardiovascular system. During a 2-year period, 175 patients with MP were included in the study. The majority of the poisonings occurred in early summertime. The most common complaint was found to be nausea and vomiting followed by mental status alterations. Methods of treatment were mainly based on gastric lavage, activated charcoal and supportive therapy. The most common ECG abnormalities in the patients with MP were sinus tachycardia, sinus arrhythmia, ST/T inversion, 1st degree AV block and QT prolongation, respectively. Cardiac markers of the patients were found to be normal. Then, patients were divided into two subgroups according to symptom onset after consumption (less than 6 hr and more than 6 hr). When the two groups were compared, prevalence of tachycardia was significantly higher in Group II. Additionally, the interval between mushroom consumption and onset of symptoms was strongly correlated with blood pressure (BP). As this interval prolonged, BP of the patients tended to increase. In conclusion, according to our results, although mechanisms need to be clarified, MP causes hypertension and ECG alterations, particularly tachycardia in patients with late-onset symptoms.

Predicting tularemia with clinical, laboratory and demographical findings in the ED.

INTRODUCTION: We aimed to determine clinical, laboratory and demographical characteristics of tularemia on admission to Emergency Department (ED). MATERIAL AND METHODS: Medical data of 317 patients admitted to ED and subsequently hospitalized with suspected tularemia between January 1, 2011, and May 31, 2015, were collected. Patients were divided into 2 groups according to microagglutination test results, as tularemia (+) and tularemia (-). RESULTS: Of the 317 patients involved, 49 were found to be tularemia (+) and 268 were tularemia (-). Mean age of the tularemia (+) patients was found to be higher than that of tularemia (-) patients. When compared to tularemia (-) patients, a significant portion of patients in tularemia (+) patients were elderly, living in rural areas and had contact with rodents. When clinical and laboratory findings of the 2 groups were compared, any statistical significance could not be determined. CONCLUSION: Tularemia is a disease of elderly people living in rural areas. Contact with rodents also increases risk of tularemia in suspected patients.

Paraoxanase as an indicator of myocardial ischemia and its utility in determining extension of ischemia.

BACKGROUND: The aim of this study was to investigate Paraoxanase 1 (PON-1) activity in patients with ST-elevated and non-ST-elevated acute myocardial infarction (AMI) and to determine its correlation with Gensini scores (GSs). METHODS: A total of 109 patients with AMI and 58 healthy subjects as control group were included in the study. Patients were divided into 2 subgroups as ST-elevated and non-ST-elevated AMI patients (Group I and II, respectively). Controls were named as Group III. PON-1 activity was determined on admission to emergency department for each group. In addition, GSs for patient groups were determined. Then, groups were compared according to their results. RESULTS: PON-1 levels in Group I and II were significantly lower when compared to Group III. Median GSs for Group I and II were 60 and 64, respectively. The cut-off value of PON-1 for diagnosis of AMI was ≤180 U/L, which was identified by receiver characteristics receiver curve analysis. However, we could not determine a significant relationship between serum PON-1 levels and GSs in patients with AMI. CONCLUSION: PON-1 levels measured on admission to emergency department may be used to rule out AMI. PON-1 levels in AMI patients are found to be inefficient in determining extension of ischemia measured by GS.

Cardiac Effects of Mad Honey Poisoning and Its Management in Emergency Department: A Review from Turkey.

Mad honey poisoning occurs when honey containing grayanotoxin is digested. The most common clinical signs and symptoms of poisoning involve findings of digestive system irritation, severe bradycardia and hypotension and central nervous system reaction. In this review, we aimed to underline the cardiac effects of mad honey poisoning. We also aimed to raise the awareness of physicians about early diagnosis and treatment of this rare entity.

Isolated unilateral oculomotor nerve palsy due to head trauma.

Unilateral oculomotor nerve palsy is a rare and challenging condition for both emergency department (ED) physicians and neurosurgeons. In this report, we present you a case of head trauma with oculomotor nerve palsy whose initial neuroimaging findings were normal. A 50-year-old female presented to our ED due to head trauma secondary to fall from height. On her physical examination, ptosis, minimal lateral deviation, and dilated pupilla unresponsive to the light were determined in the left eye. A computed tomography and magnetic resonance imaging were performed and both were found to be normal. Patient was consulted with an ophthalmologist and any sign of direct trauma to the eye was not determined. Then, the patient was consulted with a neurosurgeon and hospitalized. In some rare instances, minor traumas to the head may result in isolated oculomotor nerve palsy without accompanying findings. Neurosurgeons and ED physicians must be careful about this rare condition.

Ischemia-Modified Albumin is not Elevated in Deep Venous Thrombosis.

BACKGROUND: In this article, we aimed to determine the diagnostic role of ischemia-modified albumin (IMA) in the evaluation of patients with deep venous thrombosis (DVT). METHODS: Fifty-five patients with a diagnosis of DVT and 47 healthy subjects as the control group were included in the study. Blood samples of the patients were obtained within the first 24 hours after DVT diagnosis for IMA analysis. Patient and control groups were compared with respect to IMA levels. RESULTS: We found that HDL and albumin levels were significantly higher in the control group. However, we could not determine a significant increase in IMA levels in patients with DVT when compared to the control group. CONCLUSIONS: Our study revealed that IMA is not a useful marker in the diagnosis of DVT.

Rare etiological causes of iliofemoral deep venous thrombosis: Reports of 2 cases.

Deep venous thrombosis is frequently seen in lower extremities. However, when seen in the iliac level, mass effect of an underlying pathology must be considered. In this report, we present two cases with upper region deep venous thrombosis, which had underlying pathologies of appendicitis and non-Hodgkin lymphoma.
