BACKGROUND: The assessment of the clinical symptoms is the weakest link of the pulmonary embolism (PE) diagnostic algorithm. Despite the presence of highly sensitive and specific imaging methods, verifying PE remains difficult due to nonspecific clinical symptoms and frequently its subclinical course. OBJECTIVE: The aim of this study is to improve the recognition of PE by investigating the clinical presentation and short-term prognosis of unprovoked PE in comparison to provoked PE...

BACKGROUND: The efficacy and safety of managing patients with low-risk pulmonary embolism (PE) without hospitalization requires objective data from US medical centers. We sought to determine the 90-day composite rate of recurrent symptomatic venous thromboembolism (VTE), major bleeding events, and all-cause mortality among consecutive patients diagnosed with acute low-risk PE managed without inpatient hospitalization; and to measure patient satisfaction. METHODS: We performed a prospective cohort single-arm management study conducted from January 2013 to October 2016 in five emergency departments...

BACKGROUND: Liver resection may be complicated by unpredictable intraoperative bleeding. Pringle's maneuver was the first attempt to control bleeding,but the main problem is the duration of ischemia. Robotic surgery thanks to the magnified view,three-dimensional visualization associated and fine movement allow to perform good parenchymal dissection and identification of vascular structure. Aim of study is to evaluate blood loss and the need to perform Pringle maneuver in patients underwent robotic liver resection...

Introduction: Low back pain (LBP) is among the leading indications for the prescription of opioid analgesics in clinical practice. There is increasing evidence suggesting that these agents may have diminished efficacy in the treatment of LBP. Objectives: We evaluated the relationship between depression, the probability of receiving an opioid prescription, and the amount of morphine equivalent amounts prescribed per year among patients with LBP using nationwide data...

Kwok M Ho, Yusrah Harahsheh
Background: It is uncertain whether we can predict contrast-induced nephropathy (CIN) after CT pulmonary angiography (CTPA). This study compared the ability of a validated CIN prediction score with the Pulmonary Embolism Severity Index (PESI) in predicting CIN after CTPA. Methods: This cohort study involved critically ill adult patients who required a CTPA to exclude acute pulmonary embolism (PE). Patients with end-stage renal failure requiring dialysis were excluded...

Salmonella Infantis (SI) became endemic in Hungary where the PFGE cluster B, characterized by a large multiresistance (MDR) plasmid emerged among broilers leading to an increased occurrence in humans. We hypothesized that this plasmid (pSI54/04) assisted dissemination of SI. Indeed, Nal-Sul-Tet phenotypes carrying pSI54/04 occurred increasingly between 2011 and 2013 among SI isolates from broilers and humans. Characterization of pSI54/04 based on genome sequence data of the MDR strain SI54/04 indicated a size of ∼277 kb and a high sequence similarity with the megaplasmid pESI of SI predominant in Israel...

Gili Aviv, Ohad Gal-Mor
Quantitative real-time PCR (qRT-PCR) is a highly sensitive and reliable method for detection and quantification of DNA. When combined with a prior stage of RNA reverse transcription to generate complementary DNA (cDNA), this is a powerful approach to determine and analyze gene transcriptional expression. Real-time quantitative reverse transcription PCR has become the gold standard method in studying genes expression and virulence regulation under various genetic backgrounds (e.g., in the absence of regulators) or environmental conditions...

BACKGROUND: In patients with acute pulmonary embolism (PE), detectable levels of cardiac troponin I (cTnI) using a highly sensitive assay have been associated with increased in-hospital mortality. We sought to investigate the impact of detectable cTnI on long-term survival following acute PE. HYPOTHESIS: Detectable cTnI levels in patients presenting with acute PE predict increased long-term mortality following hospital discharge. METHODS: In a retrospective cohort study, we analyzed consecutive patients with confirmed acute PE and cTnI assay available from the index hospitalization...

RATIONALE: Probe electrospray ionization (PESI) is only applicable to liquid or wet samples. In this study, a sheath-flow PESI method for remote sampling mass spectrometry that can be applied to dry samples was developed. METHODS: An acupuncture needle (0.12 mm outer diameter, 700 nm tip diameter) was inserted into a gel-loading tip with a 0.1 mm protrusion out of the tip. Analytes were extracted by filling the latter tip with solvent and softly touching the sample surface for a short time (<1 s)...

OBJECTIVES: Intraoperative identification of tumor margins is essential to achieving complete tumor resection. However, the process of intraoperative pathological diagnosis involves cumbersome procedures, such as preparation of cryosections and microscopic examination, thus requiring more than 30 min. Moreover, intraoperative diagnoses made by examining cryosections are occasionally inconsistent with postoperative diagnoses made by examining paraffin-embedded sections because the former are of poorer quality...

Background: Numerous risk stratification tools exist to predict early post-pulmonary embolism (PE) mortality; however, few were specifically designed for use in patients with cancer. This study sought to evaluate the performance of 3 cancer-specific (RIETE, POMPE-C, and Font criteria) and 3 generic (Hestia, Pulmonary Embolism Severity Index [PESI], and Geneva prognostic score [GPS]) risk stratification tools for predicting 30-day post-PE mortality in patients with active cancer. Methods: We identified consecutive, adult, objectively confirmed patients with PE and active cancer presenting to our institution from November 2010 to January 2014...

INTRODUCTION: Whether clinical prediction rules for pulmonary embolism are accepted and used among general internal medicine residents remains uncertain. We therefore evaluated the frequency of use and acceptability of the Revised Geneva Score (RGS) and the Pulmonary Embolism Severity Index (PESI), and explored which factors were associated with rule use. MATERIALS/METHODS: In an online survey among general internal medicine residents from 10 Swiss hospitals, we assessed rule acceptability using the Ottawa Acceptability of Decision Rules Instrument (OADRI) and explored the association between physician and training-related factors and rule use using mixed logistic regression models...

A hot environment combined with physically demanding tasks can subject workers to a higher risk of heat stress. A series of regulations and guidelines have been proposed to design appropriate anti-heat stress work uniform to reduce body heat strain. The present study aimed to examine heat strain recovery in different anti-heat stress clothing ensembles after work to exhaustion in the heat. 10 healthy males performed intermittent treadmill running/walking to exhaustion, followed by 30min passive recovery sitting in a climatic chamber, which simulated the hot and humid outdoor environment (34°C temperature, 60% relative humidity, 0...

Salmonella enterica serovar Infantis is one of the prevalent Salmonella serovars worldwide. Different emergent clones of S. Infantis were shown to acquire the pESI virulence-resistance megaplasmid affecting its ecology and pathogenicity. Here, we studied two previously uncharacterized pESI-encoded chaperone-usher fimbriae, named Ipf and Klf. While Ipf homologs are rare and were found only in S. enterica subspecies diarizonae and subspecies VII, Klf is related to the known K88-Fae fimbria and klf clusters were identified in seven S...

Probe electrospray ionization (PESI), which is an ambient ionization technique, enables us to analyze intact endogenous metabolites without sample preparation. In this study, we applied the newly developed method of PESI coupled to tandem mass spectrometry (PESI/MS/MS) to analyze metabolites in mouse brain, where its lipid composition often interfere with MS-based metabolome analysis. As a result, PESI/MS/MS directly detected 25 metabolites in a mouse frontal cortex, and clearly discriminated the metabolic profiles of mice model with energy metabolism disruption from control mice...
