Article Synopsis
  • The study investigates how initial vital signs and existing medical conditions (comorbidities) impact emergency medical situations for patients in the emergency department (ED).
  • A total of 10,022 patients were analyzed, identifying significant associations between specific vital signs and comorbidities with medical emergency conditions (MECs), including conditions like hypoxia and certain chronic illnesses.
  • The findings suggest that even patients with normal vital signs and no comorbidities can still present with MECs, highlighting the need for thorough patient evaluation beyond basic triage methods.

Supervisory Control and Data Acquisition (SCADA) systems, which play a critical role in monitoring, managing, and controlling industrial processes, face flexibility, scalability, and management difficulties arising from traditional network structures. Software-defined networking (SDN) offers a new opportunity to overcome the challenges traditional SCADA networks face, based on the concept of separating the control and data plane. Although integrating the SDN architecture into SCADA systems offers many advantages, it cannot address security concerns against cyber-attacks such as a distributed denial of service (DDoS).

Supervisory Control and Data Acquisition (SCADA) systems play a crucial role in overseeing and controlling renewable energy sources like solar, wind, hydro, and geothermal resources. Nevertheless, with the expansion of conventional SCADA network infrastructures, there arise significant challenges in managing and scaling due to increased size, complexity, and device diversity. Using Software Defined Networking (SDN) technology in traditional SCADA network infrastructure offers management, scaling and flexibility benefits.

Introduction: This study aimed to compare ultrasonography (US) measurements of the upper airway to computerized tomography (CT) measurements. Our study's primary outcome is to research the accuracy of US measurements in the evaluation of upper airway diameters when CT is taken as the gold standard; the secondary outcome is to determine the time required to obtain US measurements.

Methods: This prospective study included patients ≥18 years old that had undergone thoracic or neck CT due to current clinical necessity.

Background: Ankle sprain is a frequent reason for presentation to the emergency department. Current treatment modalities include Protection, Optimal Loading, Ice, Compression, and Elevation (POLICE) and Protection, Rest, Ice, Compression, and Elevation (PRICE). This study aimed to compare the effects of PRICE and POLICE treatment protocols.

Rectus sheath hematoma (RSH) is an uncommon cause of abdominal pain associated with several risk factors including trauma, asthma, chronic obstructive pulmonary disease, pregnancy, and anticoagulation as it can be iatrogenic. Dual-antiplatelet therapy (DAPT), combined usage of a PY receptor inhibitor and aspirin, is a cornerstone treatment for patients with acute coronary syndromes. Ticagrelor is a PY receptor inhibitor with several adverse hemorrhagic complications.

Objective: Impacted tooth is a common problem that can occur at any age, causing tooth decay, root resorption, and pain in the later stages. In recent years, major advances have been made in medical imaging segmentation using deep convolutional neural network-based networks. In this study, we report on the development of an artificial intelligence system for the automatic identification of impacted tooth from panoramic dental X-ray images.

Transient receptor potential canonical channels (TRPCs) are non-selective cationic channels that play a role in signal transduction, especially in G -protein-mediated signaling cascades. TRPC5 is expressed predominantly in the brain but also in the kidney. However, its role in kidney physiology and pathophysiology is controversial.

Objective: Myocardial infarction has unfavorable effect on structural and functional properties of the myocardium, referred to as cardiac remodeling. Left ventricular mass, left ventricular mass index, and relative wall thickness are important predictors of cardiac remodeling. In this study, we investigated the effect of candesartan treatment in comparison with zofenopril treatment on echocardiographic indices of cardiac remodeling in post myocardial infarction patients.

Background: Correct application of external pelvic compression devices (binders) is crucial in managing multitrauma patients with suspected pelvic fractures to control hemorrhage. Yet, there is a lack of practical training standards for pelvic compression device application in medical school education.

Objective: This study aimed to evaluate simulation training of pelvic compression device application by medical students to determine the number of applications required to meet proficiency measured by correct application and timeliness.

Objectives: Second victim experience defines the healthcare professionals involved in unexpected adverse patient events. The Second Victim Experience and Support Tool (SVEST) is a tool used to measure the second victim experience and the desired support resources. This study aims to carry out a cross-cultural adaptation of the SVEST and to evaluate the psychometric properties of the Turkish version (T-SVEST).

A case of Guillain-Barré syndrome (GBS) was diagnosed in a patient admitted to the emergency department (ED) after ankle trauma was presented. GBS is generally defined as immune-mediated peripheral neuropathy that develops after an infection. Our patient presented to ED with ankle trauma that developed after fatigue.

Purpose: To evaluate the visual acuity of healthy and amblyopic children using sweep visual evoked potential and compare the results with those of Snellen visual acuity testing.

Methods: A total of 160 children aged 6-17 years were included in the study. Of these, 104 (65%) were aged 7-17 years old, able to verbally communicate, and did not have any systemic or ocular pathology (Group 1).

Objective: Triage is a tool used to determine patients' severity of illness or injury within minutes of arrival. This study aims to assess the reliability and validity of a new computer-based triage decision support tool, ANKUTRIAGE, prospectively.

Methods: ANKUTRIAGE, a 5-level triage tool was established considering 2 major factors, patient's vital signs and characteristics of the admission complaint.

Phosphatidylinositol 4,5-bisphosphate (PI(4,5)P or PIP) regulates the activities of numerous membrane proteins, including diacylglycerol(DAG)-activated TRPC3/6/7 channels. Although PIP binding is known to support DAG-activated TRP channel activity, its binding site remains unknown. We screened for PIP binding sites within TRPC6 channels through extensive mutagenesis.

Purpose: This study was conducted to evaluate visual function and changes in the central macular thickness of patients with unresponsive neovascular age-related macular degeneration who were switched from ranibizumab (Lucentis®) to aflibercept (Eylea®) treatment at 30 months.

Methods: This retrospective study examined patients with neovascular age-related macular degeneration who were switched to aflibercept after ≥6 previous intravitreal ranibizumab injections at 4- to 8-week intervals. All patients were switched to intravitreal aflibercept (2.

Objective: This study aimed to examine the use of point-of-care ultrasonography (POCUS) in detecting diaphragmatic dysfunction (DD) and evaluate its ability to predict noninvasive mechanical ventilation (NIV) failure in patients presented to the emergency department with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).

Methods: In this prospective cohort study, the diaphragm was examined using POCUS in patients with AECOPD. DD was defined as a diaphragm thickening fraction of less than 20% during spontaneous breathing.

Voltage-sensing phosphatases (VSP) consist of a membrane-spanning voltage sensor domain and a cytoplasmic region that has enzymatic activity toward phosphoinositides (PIs). VSP enzyme activity is regulated by membrane potential, and its activation leads to rapid and reversible alteration of cellular PIP levels. These properties enable VSPs to be used as a tool for studying the effects of phosphatidylinositol-4,5-bisphosphate (PI(4,5)P2) binding to ion channels and transporters.
