Comparison of different surfaces in resuscitation quality using a real-time feedback device: A manikin study.

Objectives: Delivering chest compressions (CCs) at the targeted depth and rate is a crucial aspect of maintaining the quality of cardiopulmonary resuscitation (CPR). Although administering CCs on a firm surface is recommended, it may not always be feasible. This study aimed to determine whether the underlying surface affects CC depth and rate using a real-time feedback device.

Posttraumatic stress disorder in health-care workers after two major earthquakes centered in Kahramanmaras, Turkey.

Objectives: Earthquakes are one of the most studied uncontrollable natural conditions that cause negative psychological consequences. Although health-care workers (HCWs) are trained to manage trauma in the out-of-hospital area, uncontrollable tragic events in the earthquake field and exposure to life-threatening situations may cause psychological disorders. This study aimed to investigate the risk of the development of probable posttraumatic stress disorder (PTSD) and the factors affecting it in HCWs working in the region during major earthquakes centered in Kahramanmaras.

Intracoronary electrocardiogram detects coronary microvascular dysfunction and ischemia in patients with no obstructive coronary arteries disease.

Background: Coronary microvascular dysfunction (CMD) is the leading cause of ischemia with no obstructive coronary arteries disease (INOCA) disease. Diagnosis of CMD relies on surrogate physiological indices without objective proof of ischemia.

Objectives: Intracoronary electrocardiogram (icECG) derived hyperemic indices may accurately and objectively detect CMD and reversible ischemia in related territory.

Ventricular arrhythmias in mitral valve prolapse syndrome and their relationship with electrocardiographic repolarization parameters.

Objective: The aim of present study is to compare ventricular and supraventricular arrhythmia incidences in subjects with and without mitral valve prolapse (MVP) syndrome and to examine if an association exists between ventricular arrhythmias and repolarization parameters in patients with MVP syndrome.

Methods: This cross-sectional study involved 41 subjects with MVP Syndrome and 41 subjects with palpitation but without MVP (control group). All subjects were subjected to lead-electrocardiogram, transthoracic echocardiography, and 24-h Holter monitoring to identify repolarization abnormalities, structural abnormalities, and supraventricular and ventricular arrhythmias.

The Effect of Platelet and Mean Platelet Volume Levels on Standard-dose Methylprednisolone Treatment Response in Primary Immune Thrombocytopenia.

Objective: Standard-dose methyl-prednisolone (methyl-Pd) is generally preferred as the first-line treatment in immune thrombocytopenia (ITP) unless there is an urgent indication to increase the platelet value. A significant proportion of patients (around 40%) does not benefit from this treatment. This study investigated whether pretreatment platelet level and other hemogram indices in patients with ITP patients can be used to predict early response to standard-dose methyl-Pd treatment.

Splenic infarction and pulmonary embolism as a rare manifestation of COVID-19.

Coronavirus disease 2019 (COVID-19) disease leads to a hypercoagulable state and associated with thrombotic events that can cause mortality and morbidity. Thrombotic events include both venous and arterial thrombosis. In this case report, we present a 68-year-old COVID-19 patient with multisystemic infarction who was admitted to the hospital by splenic infarction and later pulmonary embolism diagnosed during the stay in hospital despite anticoagulant use.

Impact of Multimodality Imaging on the Diagnosis of Left Ventricular Apical Thrombus in Patients After Anterior Myocardial Infarction.

Background: The presence of the left ventricle (LV) apical thrombus is one of the most critical complications of anterior myocardial infarction (MI). Due to the high risk of systemic embolization, the determination of LV apical thrombus (LVAT) is essential. We aimed to compare the two-dimensional echocardiography (2DE), contrast-2DE and real-time three-dimensional echocardiography (RT-3DE) in the diagnosis of LVAT and determine which imaging modality is superior.

Circulating Levels of MicroRNAs in Hypertrophic Cardiomyopathy: The Relationship With Left Ventricular Hypertrophy, Left Atrial Dilatation and Ventricular Depolarisation-Repolarisation Parameters.

Background: MicroRNAs are small, endogenous, non-coding RNAs that regulate the expression of many genes. It has recently been shown that circulating microRNAs may be biomarkers of hypertrophy and fibrosis in patients with hypertrophic cardiomyopathy (HCM).

Objective: To determine whether circulating levels of microRNAs involved in HCM are associated with electrocardiographic and echocardiographic parameters.

Wide QRS Complex and Lateral ST-T Segment Abnormality Are Associated With Worse Clinical Outcomes in COVID-19 Patients.

Background: The information on electrocardiographic features of patients with coronavirus disease 2019 (COVID-19) is limited. Our aim was to determine if baseline electrocardiographic features of hospitalized COVID-19 patients are associated with markers of myocardial injury and clinical outcomes.

Methods: In this retrospective, single center cohort study, we included 223 hospitalized patients with laboratory-confirmed COVID-19.

Approach to a Patient with Stroke After Flying.

Arriving at a definitive diagnosis in case of a patient with neurological symptoms after a low altitude flight is very critical, while at the same time presenting a dilemma in aeromedical decision making. Symptoms of stroke can closely mimic those of neurologic manifestations of decompression sickness. This paper discusses the approach to a case of a 28-year-old male helicopter passenger who developed left-sided numbness of the body after a 1.

The relationship between T-wave peak-to-end interval and hemodynamic parameters in patients with pulmonary arterial hypertension.

Background: T-wave peak-to-end interval (TPEI) is a measure of repolarization dispersion on surface electrocardiogram (ECG). TPEI has been reported as a prognostic parameter with heart disorders. In this study, we aimed to evaluate the relationship between echocardiogram-derived right heart parameters, right heart catheterization (RHC) measurements, and TPEI in patients with precapillary pulmonary arterial hypertension (PAH).

The success of endotracheal intubation with a modified laryngoscope using night vision goggles.

Background: Endotracheal intubation (ETI) procedure in the combat area differs from prehospital trauma life support procedures because of the danger of gunfire and the dark environment. We aimed to determine the success, difficulty degree, and duration of ETI procedures with a classical laryngoscope (CL) in a bright room and with a modified laryngoscope (ML) model in a dark room.

Methods: All interventions were performed by a combatant medical staff of 10 members.

A new perspective on life-saving procedures in a battlefield setting: Emergency cricothyroidotomy, needle thoracostomy, and chest tube thoracostomy with night vision goggles.

Background: In the patients with multiple and serious trauma, early applications of life-saving procedures are related to improved survival. We tried to experimentally determine the feasibility of life-saving interventions that are performed with the aid of night vision goggles (NVG) in nighttime combat scenario.

Methods: Chest tube thoracostomy (CTT), emergency cricothyroidotomy (EC), and needle thoracostomy (NT) interventions were performed by 10 combatant medical staff.

A Study on the Tactical Safety of Endotracheal Intubation Under Darkness.
