Heavy metal and trace element alterations in patients during a migraine attack.

OBJECTIVE: The aim of the study was to determine the heavy metal and trace element (HMTE) profile in patients with migraine (PwM) and to compare it to that of healthy individuals without migraine. BACKGROUND: Migraine is a universal disease that affects more than 10% of the world's population; however, its pathophysiology is still obscure. METHODS: A total of 100 participants were included in this prospective matched case-control study (50 PwM during acute attack and 50 age- and sex-matched healthy controls). The study was conducted in the university hospital in Yozgat, Turkey, where the inductively coupled plasma mass spectrometry system was used to measure the HMTE profile. The calibration curve was created with 11 points for heavy metals (arsenic [As], cadmium [Cd], cobalt [Co], lead [Pb], mercury [Hg], nickel [Ni], and tin [Sn]) and trace elements (antimony [Sb], chromium [Cr], copper [Cu], iron [Fe], magnesium [Mg], manganese [Mn], molybdenum [Mo], and zinc [Zn]). RESULTS: The median age was 27 (23-37) years, and the female/male ratio was 37/13 for both groups. The PwM group had significantly higher As, Co, Pb, and Ni levels among the heavy metals (p = 0.033, 0.017, 0.022, and 0.021, respectively). Also, PwM had significantly lower Cr, Mg, and Zn levels among the trace elements (p = 0.007, 0.024, and < 0.001, respectively). The only trace element that was elevated in the PwM group was Mn (p = 0.001). The PwM and control groups did not differ in terms of Cd, Sn, Sb, Cu, Fe, and Mo (p = 0.165, 0.997, 0.195, 0.408, 0.440, and 0.252, respectively). CONCLUSION: Some HMTE parameters are altered in PwM, which may provide additional insight into understanding migraine etiology.

Comparative analysis of ChatGPT, Gemini and emergency medicine specialist in ESI triage assessment.

INTRODUCTION: The term Artificial Intelligence (AI) was first coined in the 1960s and has made significant progress up to the present day. During this period, numerous AI applications have been developed. GPT-4 and Gemini are two of the best-known of these AI models. As a triage system The Emergency Severity Index (ESI) is currently one of the most commonly used for effective patient triage in the emergency department. The aim of this study is to evaluate the performance of GPT-4, Gemini, and emergency medicine specialists in ESI triage against each other; furthermore, it aims to contribute to the literature on the usability of these AI programs in emergency department triage. METHODS: Our study was conducted between February 1, 2024, and February 29, 2024, among emergency medicine specialists in Turkey, as well as with GPT-4 and Gemini. Ten emergency medicine specialists were included in our study but as a limitation the emergency medicine specialists participating in the study do not frequently use the ESI triage model in daily practice. In the first phase of our study, 100 case examples related to adult or trauma patients were extracted from the sample and training cases found in the ESI Implementation Handbook. In the second phase of our study, the provided responses were categorized into three groups: correct triage, over-triage, and under-triage. In the third phase of our study, the questions were categorized according to the correct triage responses. RESULTS: In the results of our study, a statistically significant difference was found between the three groups in terms of correct triage, over-triage, and under-triage (p < 0.001). GPT-4 was found to have the highest correct triage rate with an average of 70.60 (±3.74), while Gemini had the highest over-triage rate with an average of 35.2 (±2.93) (p < 0.001). The highest under-triage rate was observed in emergency medicine specialists (32.90 (±11.83)). In the ESI 1-2 class, Gemini had a correct triage rate of 87.77%, GPT-4 had 85.11%, and emergency medicine specialists had 49.33%. CONCLUSION: In conclusion, our study shows that both GPT-4 and Gemini can accurately triage critical and urgent patients in ESI 1&2 groups at a high rate. Furthermore, GPT-4 has been more successful in ESI triage for all patients. These results suggest that GPT-4 and Gemini could assist in accurate ESI triage of patients in emergency departments.

Adalimumab (Humira®) Induced Recurrent Peritonsillar Abscess in A Patient Received Three Different Anti-TNF Therapies: A Case Report.

Anti-tumor necrosis factor agents are widely used in treating ankylosing spondylitis, but they increase the risk of infection by suppressing the immune response. Therefore, physicians should be careful about recurrent infections in patients under anti-tumor necrosis factor agents.

The diagnostic and prognostic value of serum neurogranin in acute ischemic stroke.

OBJECTIVES: Stroke is a frequently encountered life-threatening medical condition in emergency departments (EDs). Despite all worldwide efforts, a reliable circulating biomarker has not been identified yet. This study investigates the diagnostic and prognostic value of neurogranin (Ng) in acute ischemic stroke (AIS). METHODS: This prospective case-control study was conducted on ED patients with AIS and healthy volunteers. We collected the basic demographics, measured serum Ng levels of the patients vs. controls, and followed up the patient group for 6-month by phone or clinical notes to assess the functional outcomes. RESULTS: Data analysis was completed with 142 subjects (86 patients vs. 55 controls). The groups did not differ in terms of age and gender. The median serum Ng level of the patient group was significantly higher compared to the control group [160.00 (75.93) vs. 121.26 (90.35) ng/mL and p Ë‚ 0.001, respectively]. Serum Ng level of 25 patients admitted to the ED within the first 6 hours from the onset of AIS was 177.93 (24.03) ng/mL, while serum Ng level of 61 patients admitted to the ED within 6-24 hours was 131.84 (76.44) ng/mL. AUROC results were 0.717 vs. 0.868 vs. 0.874 for stroke patients admitted during the first 24 hours, 6 hours, and 4.5 hours after the onset, respectively. Lesion volume, NIHSS, and modified Rankin Scale scores (mRS) at admission showed no significant correlation with Ng levels as well as 6-month mortality and 6-month mRS. CONCLUSIONS: Timely AIS diagnosis is still a challenge for emergency departments due to the dependency on imaging. Serum Ng can be a promising diagnostic biomarker for AIS patients admitted in the first 24 hours. Even it outperformed in the first 4.5 and 6-hour time windows. However, it did not show a significant prognostic value.

Ability of Bedside Ultrasonography to Detect Pediatric Nasal Bone Fractures.

OBJECTIVES/HYPOTHESIS: The aims of this study were to evaluate the diagnostic test features of bedside ultrasonography in pediatric patients with nasal trauma and to investigate whether it is a preferable alternative method to conventional radiography (CR). STUDY DESIGN: Cross-sectional prospective study. METHODS: This prospective study was conducted from March 1, 2019, through November 1, 2019. Thirty-one patients under the age of 18 years who had nasal trauma were consecutively included. CR and ultrasonographic imaging tests were investigated in patients with clinical indications for nasal bone fracture. The sensitivity, specificity, and accuracy of ultrasonography and CR were calculated with respect to detecting nasal fractures according to the gold standard method. RESULTS: Participants were between 3 and 16 years old and the median age was 8 (5-13) years. Nasal bone fracture was clinically detected in 18 patients. While 13 of these fractures were detected with ultrasonography, only 11 were also detected with CR. The sensitivity and specificity of ultrasonography and CR in detecting nasal fractures were 72.2% (95% confidence interval [CI]: 46.5-90.3) and 76.9% (95% CI: 46.2-95.0) for ultrasonography and 61.1% (95% CI: 35.8-82.7) and 69.2% (95% CI: 38.6-90.9) for CR. CONCLUSIONS: According to the results of this study, ultrasonography may be used with confidence as a first imaging method in the investigation of nasal fractures, particularly with consideration for avoiding the effects of radiation as much as possible. Our findings point to the next step of conducting trials with a greater number of patients in order to define the diagnostic test features of ultrasonography in pediatric patients.
