Right ventricular outflow tract doppler flow abnormalities suggestive of pulmonary embolism - case series and review.

Background: Pulmonary embolism (PE) is one of the most challenging diagnoses in emergency medicine, mainly because symptoms range from asymptomatic disease to sudden death. The role of echocardiography in the workup of suspected PE has been supportive and used primarily to assess the right ventricular (RV) size and function, which is important for risk stratification. Several echocardiographic parameters described in the literature lack the desired accuracy.

Unnecessary repetitions of C-reactive protein and leukocyte count at the emergency department observation unit contribute to higher hospital admission rates.

Objectives: The aim of the present study was to assess the effect of repeated laboratory measurement of C-reactive protein (CRP) and leukocyte count on the decision whether to admit or dicharge the patient with localized infections who received antibiotics at the Emergency Department (ED) observation unit.

Methods: Adult patients with respiratory, urinary tract and abdominal infections, observed at the ED after antibiotic administration, in whom repeated measurements of CRP and leukocyte count were performed within 24 h, were included. They were initially grouped as planned discharge, planned admission and unclear attitude towards admission.

Gender motivational gap and contribution of different teaching approaches to female students' motivation to learn physics.

This research focuses on potential gender differences in motivation to learn Physics with the aim to determine the weakest female motivational components to learn Physics and the contribution of different teaching approaches (using real and virtual experiments) on those components and motivation for learning Physics in general. These two approaches were chosen as the most commonly used approaches in physics but without clear compared indication on females' motivation. The standardized questionnaire SMTSL (Student's Motivation towards Science Learning) is used for the measurements.

HIGH-DOSE INSULIN EUGLYCEMIC THERAPY.

Calcium channel blockers and beta-blockers toxicity/poisoning are one of the most common causes of poisoning. More importantly, they are among the deadliest types of poisoning caused by cardiac drugs that emergency physicians can encounter. Common toxidrome caused by these medications includes the following symptoms: hypotension, bradycardia, hypoglycemia/hyperglycemia, hypothermia, arrhythmia, and seizures.

Cherenkov Radiation Detection on a LS Counter for Ra Determination in Water and Its Comparison with Other Common Methods.

Reliable determination of Ra content in drinking water, surface water and groundwater is required for radiological health-risk assessment of populations and radiation-dose calculations after ingestion and inhalation. This study aimed to determine Ra presence in the untreated water samples on a liquid scintillation counter via Cherenkov radiation detection. Cherenkov counting is a faster, simpler, less expensive technique than other commonly used methods for Ra determination.

Work from home and musculoskeletal pain in telecommunications workers during COVID-19 pandemic: a pilot study.

One of the side-effects of the COVID-19 pandemic is a global change in work ergonomic patterns as millions of people replaced their usual work environment with home to limit the spread of the severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) infection. The aim of our cross-sectional pilot study was to identify musculoskeletal pain that may have resulted from this change and included 232 telecommunications company workers of both genders [121 (52.2 %) men aged 23-62 (median 41; interquartile range 33-46 yrs.

CHOLESTEROL AND CHLORIDE IN ACUTE HEART FAILURE.

Detecting predictors of poor outcome is crucial for understanding the underlying pathophysiology of heart failure (HF) and thus creating new therapeutic concepts. It is well established that low serum lipid levels are associated with unfavorable outcomes in HF patients. Several studies examined the association between serum lipids and established predictors of mortality in HF patients.

Serum concentrations of free fatty acids are associated with 3-month mortality in acute heart failure patients.

Background Plasma free fatty acids (FFA) are higher in heart failure (HF) patients compared to healthy controls. Considering that the extent of FFA elevation in HF might mirror the severity of HF, we hypothesized that the serum levels of FFA may be a useful prognostic indicator for 3-month mortality in acute heart failure (AHF). Methods We analyzed the serum samples of AHF patients obtained at admission to the emergency department.

Author Correction: Acute Heart Failure developed as worsening of Chronic Heart Failure is associated with increased mortality compared to de novo cases.

A correction to this article has been published and is linked from the HTML and PDF versions of this paper. The error has been fixed in the paper.

Serum Concentrations of Citrate, Tyrosine, 2- and 3- Hydroxybutyrate are Associated with Increased 3-Month Mortality in Acute Heart Failure Patients.

Considering the already established relationship between the extent of the metabolic dysfunction and the severity of heart failure (HF), it is conceivable that the metabolomic profile of the serum may have a prognostic capacity for 3-month mortality in acute heart failure (AHF). Out of 152 recruited patients, 130 serum samples were subjected to the metabolomic analyses. The 3-month mortality rate was 24.

Acute Heart Failure developed as worsening of Chronic Heart Failure is associated with increased mortality compared to de novo cases.

Acute heart failure (AHF) emerges either de novo or from worsening of chronic heart failure (CHF). The aim of the present study was to evaluate the association between worsening of CHF and mortality in AHF patients. Out of 152 included AHF patients, 47 (30.

Serum concentrations of asymmetric and symmetric dimethylarginine are associated with mortality in acute heart failure patients.

Background: Serum concentrations of asymmetric (ADMA) and symmetric (SDMA) dimethylarginine are established predictors of total and cardiovascular mortality. However, the predictive capacity of ADMA and SDMA for hospital and 3-months mortality of patients with acute heart failure (AHF) is unknown.

Methods & Results: Out of 152 included AHF patients, 79 (52%) were female, and the mean patient age was 75.

Metabolic Syndrome Modulates Association between Endothelial Lipase and Lipid/Lipoprotein Plasma Levels in Acute Heart Failure Patients.

We hypothesised that the established association of endothelial lipase (EL) plasma levels with atherogenic lipid profile is altered in acute heart failure (AHF) and additionally affected by overlapping metabolic syndrome (MetS). We examined the association of EL plasma levels and lipid/lipoprotein plasma levels in AHF patients without and with overlapping MetS. The study was performed as a single-centre, observational study on 152 AHF patients, out of which 85 had overlapping MetS.

[EUROPEAN RESUSCITATION COUNCIL GUIDELINES FOR RESUSCITATION 2015].

Adult basic life support and automated external defibrillation – Interactions between the emergency medical dispatcher, the bystander who provides CPR and the timely deployment of an AED is critical. All CPR providers should perform chest compressions, those who are trained and able should combine chest compressions and rescue breaths in the ratio 30:2. Defibrillation within 3–5 min of collapse can produce survival rates as high as 50–70%.

Metrics of High-Density Lipoprotein Function and Hospital Mortality in Acute Heart Failure Patients.

Objective: The functionality of high-density lipoprotein (HDL) is impaired in chronic ischaemic heart failure (HF). However, the relationship between HDL functionality and outcomes in acute HF (AHF) has not been studied. The present study investigates whether the metrics of HDL functionality, including HDL cholesterol efflux capacity and HDL-associated paraoxonase (PON)-1 arylesterase (AE) activity are associated with hospital mortality in AHF patients.

Hypochloraemia as a predictor of developing hyponatraemia and poor outcome in acute heart failure patients.

Aims: Heart failure (HF) is a major public health issue currently affecting more than 23 million patients worldwide. Hyponatraemia has been shown to be a predictor of poor outcome in patients with acute and chronic HF. Therefore, we aimed at finding a marker for early detection of patients at risk for developing hyponatraemia.

[COLONIC MUCO-SUBMUCOSAL ELONGATED POLYP: A CASE REPORT AND LITERATURE REVIEW].

Recently a new entity has been described--a colonic muco-submucosal elongated polyp (CMSEP)--that did not fall into traditional classification of colorectal polyps. The CMSEP is endoscopically characterised by elongated, worm-like appearance with a normal overlying mucosa. Histologic characteristics of the CMSEP comprise mucosa and expanded submucosa with dilated vasculature and lymphatics.

[Clinical characteristics of patients with a double pylori].

Double pylorus (DP), is a form of gastroduodenal fistula, which consists of a short accessory canal from the gastic antrum to the duodenal bulb, and mostly occrus in the background of peptic ulcer disease. Prevalence, as well long-term follow-up of patients with DP is less elucidated in western countries. Aim of our study was to analyse demografic, clinical and endoscopic characteristics in our case-series.

Combined use of clips and nylon snare ("tulip-bundle") as a rescue endoscopic bleeding control in a mallory-weiss syndrome.

Mallory-Weiss syndrome (MWS) accounts for 6-14% of all cases of upper gastrointestinal bleeding. Prognosis of patients with MWS is generally good, with a benign course and rare recurrence of bleeding. However, no strict recommendations exist in regard to the mode of action after a failure of primary endoscopic hemostasis.
