February 6th, Kahramanmaras earthquakes and the disaster management algorithm of adult emergency medicine in Turkey: An experience review.

This compilation covers emergency medical management lessons from the February 6th Kahramanmaras earthquakes. The objective is to review relevant literature on emergency services patient management, focusing on Koenig's 1996 Simple Triage and Rapid Treatment (START) and Secondary Assessment of Victim Endpoint (SAVE) frameworks. Establishing a comprehensive seismic and mass casualty incident (MCI) protocol chain is the goal. The prehospital phase of seismic MCIs treats hypovolemia and gets patients to the nearest hospital. START-A plans to expedite emergency patient triage and pain management. The SAVE algorithm is crucial for the emergency patient secondary assessment. It advises using Glasgow Coma Scale, Mangled Extremity Severity Score, Burn Triage Score, and Safe Quake Score for admission, surgery, transfer, discharge, and outcomes. This compilation emphasizes the importance of using diagnostic tools like bedside blood gas analyzers and ultrasound devices during the assessment process, drawing from 6 February earthquake research. The findings create a solid framework for improving emergency medical response strategies, making them applicable in similar situations.

Comparison of cetylpyridinium chloride and cetyltrimethylammonium bromide extractive procedures for quantification and characterization of human urinary glycosaminoglycans.

BACKGROUND: Glycosaminoglycans (GAGs) are natural complex polysaccharides that are important in several pathological processes. Urinary GAGs have long been investigated for their possible modifications in many pathological conditions. In some cases, they have been found to have diagnostic utility. As a result, the measurement of GAGs in urine is gradually gaining importance. Cetylpyridinium chloride (CPC) and cetyltrimethylammonium bromide (CETAB) are generally used to extract urinary GAGs prior to analysis. In this study, we evaluated the extraction of human urinary GAGs using CPC in comparison with CETAB. METHODS: Extracted urinary GAGs were qualitatively and quantitatively analyzed by agarose-gel electrophoresis in the presence of sequential staining and densitometric scanning. This procedure was able to give more reproducible and reliable results for urinary GAGs, and high performance liquid chromatography (HPLC) was used for the evaluation of chondroitin sulfate (CS) disaccharides. RESULTS: Differences were observed between CPC and CETAB extract protocols. The absolute amount of CS evaluated by electrophoresis was found to be similar for the two protocols. However, the heparan sulfate (HS) concentration was calculated to be approximately 3.3 times greater for CPC than CETAB. When calculated in relative percentage, 33.6% HS was determined for CPC and 10.0% for CETAB. These results show a quantitative expression for greater recovery of HS by using CPC protocol than CETAB. No significant differences were found between CS quantified by agarose-gel and HPLC. In addition, no differences were observed for the CS disaccharide composition purified by using CPC or CETAB, and quite similar results were observed for 4s/6s disaccharide ratios and charge density values. CONCLUSIONS: Extract procedures for urinary GAGs using CPC or CETAB are able to recover similar amounts of CS quantified by agarose-gel electrophoresis and HPLC. However, CPC yields greater recovery of HS than the CETAB protocol; an increase of approximately 3.3 times as evaluated by electrophoresis. This different capacity of HS extraction between CPC and CETAB should be considered when urinary GAGs of subjects affected by various diseases and related pharmacological treatments are considered, or meta-analysis is performed comparing various studies and trials performed under different experimental conditions.

Oxidative stress parameters in patients with slow coronary flow.

INTRODUCTION: We investigated the probable role of free-radical damage in the pathogenesis of slow coronary flow (SCF) by using oxidative stress parameters. METHODS: Sixty-four patients with angiographically proven SCF and 63 patients with normal coronary flow (NCF) pattern with similar risk profiles were enrolled in this study. We measured erythrocyte superoxide dismutase (SOD), reduced glutathione (GSH), serum malondialdehyde (MDA), catalase and myeloperoxidase (MPO) levels in all subjects. RESULTS: There were statistically significant differences in the levels of erythrocyte SOD, GSH and serum MDA between the 2 groups. Serum MDA (P = 0.003) and erythrocyte SOD levels (P = 0.0001) were increased in the SCF group. The level of erythrocyte GSH (P = 0.010) was lower in patients with SCF. There were no differences between the groups' serum catalase (P = 0.682) and MPO levels (P = 0.070). CONCLUSION: Our data showed that in patients with SCF, serum MDA and erythrocyte SOD levels were increased while erythrocyte GSH levels were decreased significantly, compared with NCF patients. These results indicate that free-radical damage may play a role in the pathogenesis of SCF.
