OBJECTIVE: Evaluate physiological and perceptual responses using a phase change cooling (PCC) garment during simulated work in the heat. METHODS: Twenty males wearing compression undergarments, coverall suit, gloves, and hard-hat, completed two randomly assigned trials (with PCC inserts or control, CON) of simulated industrial tasks in the heat (34.2 ± 0.05 °C, 54.7 ± 0.3%RH). Trials consisted of two 20 min work bouts, a maximum performance bout, and 10 min of recovery...

Accurately assessing the physiological status of firefighters during work in the heat is critical to ensuring their safety. Evaluating core temperatures (Tc) in the field is problematic due to cost and limitations in technology and accuracy. As such, fire services rely on individual perceptions of wellbeing. The present study aimed to establish whether perceptual responses measured using the perceptual strain index (PeSI), calculated from rate of perceived exertion (RPE) and thermal sensation (TS), could reliably predict the physiological strain (PSI) encountered by experienced firefighters working in a hot environment...

INTRODUCTION: The Pulmonary Embolism Severity Index (PESI) is a validated prognostic score to estimate the 30-day mortality of emergency department (ED) patients with acute pulmonary embolism (PE). A simplified version (sPESI) was derived but has not been as well studied in the U.S. We sought to validate both indices in a community hospital setting in the U.S. and compare their performance in predicting 30-day all-cause mortality and classification of cases into low-risk and higher-risk categories...

BACKGROUND: Pulmonary embolism (PE) is associated with high all-cause and PE-related mortality and requires individualized management. After confirmation of PE, a refined risk stratification is particularly warranted among normotensive patients. Previous prognostic models favored combinations of echocardiography or computed tomography suggestive of right ventricular (RV) dysfunction together with biomarkers of RV dysfunction (natriuretic peptides) or myocardial injury (cardiac troponins) to identify candidates for thrombolysis or embolectomy...

In the emergency department, the management of patients with pulmonary embolism depends on the early mortality risk. Outpatient care is possible in low-risk patients. We present the existing scores and the strategy proposed by the North Alps Emergency Network, which uses the simplified PESI score (Pulmonary Embolism Severity Index) to select those low-risk patients, candidates for early discharge.

This study aims to examine the benefits of wearing a new construction work uniform in real-work settings. A field experiment with a randomized assignment of an intervention group to a newly designed uniform and a control group to a commercially available trade uniform was executed. A total of 568 sets of physical, physiological, perceptual, and microclimatological data were obtained. A linear mixed-effects model (LMM) was built to examine the cause-effect relationship between the Perceptual Strain Index (PeSI) and heat stressors including wet bulb globe temperature (WBGT), estimated workload (relative heart rate), exposure time, trade, workplace, and clothing type...

OBJECTIVE: Adoption of clinical decision support (CDS) tools by clinicians is often limited by workflow barriers. We sought to assess characteristics associated with clinician use of an electronic health record-embedded clinical decision support system (CDSS). METHODS: In a prospective study on emergency department (ED) activation of a CDSS tool across 14 hospitals between 9/1/14 to 4/30/15, the CDSS was deployed at 10 active sites with an on-site champion, education sessions, iterative feedback, and up to 3 gift cards/clinician as an incentive...

Basic knowledge of pulmonary embolism is relevant to most practicing physicians. Many medical specialties care for patients with increased risk of pulmonary embolism, why recognition of relevant symptoms, a thorough medical history, assessment of the clinical condition of the patient and possibly referral to a relevant facility should be a part of the skills of all clinicians. Sudden onset dyspnea, chest pain, syncope and hemoptysis are essential symptoms of pulmonary embolism, and in most of these patients basic investigations like arterial blood gas analysis, electrocardiogram, chest x-ray and biochemical analyses are appropriate...

UNLABELLED: Salmonella enterica serovar Infantis is one of the prevalent salmonellae worldwide. Recently, we showed that the emergence of S Infantis in Israel was facilitated by the acquisition of a unique megaplasmid (pESI) conferring multidrug resistance and increased virulence phenotypes. Here we elucidate the ecology, transmission properties, and regulation of pESI. We show that despite its large size (~280 kb), pESI does not impose a significant metabolic burden in vitro and that it has been recently fixed in the domestic S Infantis population...

INTRODUCTION: Right ventricular (RV) dysfunction has proved to be an important predictor of morbidity and mortality in patients with pulmonary embolism (PE). Tricuspid annular plane systolic excursion (TAPSE) is one of the parameters that have been validated as predictor of outcomes. The aim of our study was to evaluate the performance (sensitivity and specificity) of high-sensitivity cardiac troponin T (hs-cTnT) to predict RV dysfunction defined as TAPSE <16 mm. METHODS: We conducted a single-center retrospective analysis of 40 patients prospectively included...

Pancreatico-jejunal anastomosis after pancreatoduodenectomy still represents the Achilles' heel of the procedure: the failure of this anastomosis is relatively common and it is the main cause of post-operative morbidity and mortality. Studies have described different reconstruction strategies for the control of the development of post-operative pancreatic fistula, but the strategy to obtain a safer pancreatico-jejunal anastomosis is still far from satisfaction. We report a novel variation of the invagination technique based on preliminary clinical experience in 8 patients who underwent pancreatico-jejunal anastomosis after pancreatoduodenectomy in our hepatobiliopancreatic center from 2008 to 2014...

In this work, a synchronized polarization induced electrospray ionization (SPI-ESI) method is developed and applied for the analysis of single-cell samples. In SPI-ESI, periodic alternating current square wave voltage (AC-SWV) is applied to induce the bipolar spray and both positive-ion and negative-ion mass spectra are obtained through one measurement by synchronizing the mode of mass analyzer with the bipolar spray process. Compared with conventional nanoelectrospray ionization (nESI, flow rate < 1000 nL/min), ultralow spray flow rate (pico-electrospray ionization, pESI, flow rate < 1000 pL/min) is achieved in SPI-ESI without loss of its sensitivity...

BACKGROUND: Acute pulmonary embolism is a serious medical condition that has a substantial global impact. Inflammation plays a role in the pathophysiology and prognosis of acute pulmonary embolism (APE). The aim of the present study was to investigate the prognostic value of admission parameters for complete blood count (CBC) in APE. METHODS: A total of 203 patients who were hospitalized with diagnosed APE were retrospectively enrolled in the study. Clinical data, PESI scores, admission CBC parameters, neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were all recorded...

BACKGROUND: The need for anticoagulation therapy (AC) in patients with subsegmental pulmonary embolism (SSPE) diagnosed by computed tomography of the pulmonary arteries (CTPA) has been questioned, as these patients run low risk for recurrent venous thromboembolism (VTE) during 3 months of follow-up. Whether this applies also to patients with small PE diagnosed with pulmonary scintigraphy has not yet been evaluated, however. METHODS: We therefore retrospectively evaluated 54 patients (mean age 62 ± 19 years, 36 [67 %] women) with small PE diagnosed by ventilation/perfusion singe photon emission computed tomography (V/P SPECT) who did not receive conventional long-term AC...

BACKGROUND: Acute symptomatic pulmonary embolism (PE) varies in its clinical manifestations in patients with cancer and entails specific issues. The objective is to assess the performance of five scores (PESI, sPESI, GPS, POMPE, and RIETE) and a clinical decision rule to predict 30-day mortality. METHODS: This is an ambispective, observational, multicenter study that collected episodes of PE in patients with cancer from 13 Spanish centers. The main criterion for comparing scales was the c-indices and 95% confidence intervals (CIs) of the models for predicting 30-day mortality...

Nine prognostic scores for pulmonary embolism (PE), based on retrospective and prospective studies, published between 2000 and 2014, have been analyzed and compared. Most of them aim at identifying PE cases with a low risk to validate their ambulatory care. Important differences in the considered outcomes: global mortality, PE-specific mortality, other complications, sizes of low risk groups, exist between these scores. The most popular score appears to be the PESI and its simplified version. Few good quality studies have tested the applicability of these scores to PE outpatient care, although this approach tends to already generalize in the medical practice...

The European Society of Cardiology (ESC) has proposed an updated risk stratification model for death in patients with acute pulmonary embolism based on clinical scores (Pulmonary Embolism Severity Index (PESI) or simplified PESI (sPESI)), right ventricle dysfunction (RVD) and elevated serum troponin (2014 ESC model).We assessed the ability of the 2014 ESC model to predict 30-day death after acute pulmonary embolism. Consecutive patients with symptomatic, confirmed pulmonary embolism included in prospective cohorts were merged in a collaborative database...
