OBJECTIVE: The purpose of this article is to compare outcomes of findings seen on one view only from screening full-field digital mammography (FFDM) and FFDM plus digital breast tomosynthesis (DBT). MATERIALS AND METHODS: A retrospective review was performed of 103,070 consecutive screening mammograms obtained from February 2011 through June 2014 at two community-based breast centers. Recalled findings prospectively seen on one view only were analyzed. Pearson chi-square test and Fisher exact test were performed, and 95% CIs were determined...

OBJECTIVE: In an emergency department (ED) sample, we investigated the concordance between identification of suicide-related visits through standardized comprehensive chart review versus a subset of three specific chart elements: ICD-9-CM codes, free-text presenting complaints, and free-text physician discharge diagnoses. METHODS: Review of medical records for adults (≥18 years) at eight EDs across the United States. RESULTS: A total of 3,776 charts were reviewed...

BACKGROUND: The differentiation between intracranial atherosclerotic stenosis (ICAS) and intracranial embolism as the immediate cause of acute ischemic stroke requiring endovascular therapy is important but challenging. In cases of ICAS, we often observe a phenomenon we call the microcatheter "first-pass effect," which is temporary blood flow through the occluded intracranial artery when the angiographic microcatheter is initially advanced through the site of total occlusion and immediately retrieved proximally...

Obstructive sleep apnoea (OSA) is the main secondary form associated with resistant hypertension (RH), but it is largely underdiagnosed and consequently undertreated in clinical practice. The Berlin questionnaire (BQ) is a useful tool among general population, but seems to not perform well among patients with RH. Recently, NoSAS score was validated in a large population, however, has not been tested in the cardiovascular scenario. Thus, we aimed to compare BQ versus the NoSAS score as screening tools for OSA in RH...

BACKGROUND: Functional hemodynamic parameters such as stroke volume and pulse pressure variation (SVV and PPV) have been shown to be reliable predictors of fluid responsiveness in mechanically ventilated patients. Today, different minimally- and non-invasive hemodynamic monitoring systems measure functional hemodynamic parameters. Although some of these parameters are described by the same name, they differ in their measurement technique and thus may provide different results. We aimed to test the performance of seven functional hemodynamic parameters simultaneously in the same clinical setting...

INTRODUCTION: Relationship between regional tissue oxygenation (rSO2 ) and microcirculatory changes during cardiac arrest (CA) are still unclear. Therefore, we designed an experimental study to correlate rSO2 , microcirculation and systemic hemodynamic parameters in a porcine model of CA. METHODS: Ventricular fibrillation was induced in 24 female pigs (50±3kg) and left for three minutes untreated followed by five minutes of mechanical CPR. Regional and peripheral saturations were assessed by near-infrared spectroscopy, sublingual microcirculation by Sidestream Dark Field technology and continuous hemodynamic parameters, including systemic blood pressure (MAP) and carotid blood flow (CF), during baseline, CA and CPR periods...

This study sought to investigate genes related to recurrent risk and establish a support vector machine (SVM) classifier for prediction of recurrent risk in gastric cancer (GC).Based on the gene expression profiling dataset GSE26253, feature genes that were significantly associated with survival time and status were screened out. Subsequently, protein-protein interaction (PPI) network was constructed for these feature genes, and genes in this network was optimized using betweenness centrality algorithm in order to identify genes potentially correlated with GC (named as GCGs)...

PURPOSE: Patients with cancer are an especially vulnerable population to potential drug-drug interactions (DDIs). This makes it important to adequately screen them for DDIs. The objective of this study was to compare the abilities of nine DDI screening tools to detect clinically relevant interactions with oral oncolytics. METHODS: Subscription-based tools (ie, PEPID, Micromedex, Lexicomp, Facts & Comparisons) and free tools (ie, Epocrates Free, Medscape, Drugs...

PURPOSE: To demonstrate accuracy of duplex Doppler ultrasonography (DUS) for the evaluation of native-vein arteriovenous fistula (AVF) dysfunction in end-stage renal disease patients. METHODS: This retrospective study included 60 patients with dysfunctioning native-vein AVF evaluated with DUS and digital subtraction angiography (DSA) whose results were compared for detection, identification, and localization of AVF lesions. We calculated sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of DUS and evaluated the agreement between DUS and DSA by the Cohen's kappa coefficient (κ)...

Background: In the setting of solitary pulmonary nodules (SPNs), fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (18 F-FDG-PET/CT) is considered a useful non-invasive diagnostic tool though false positive (FP) and false negative (FN) results affects accuracy due to different conditions, such as inflammatory diseases or low-uptake neoplasms. Aim of this study is to evaluate overall diagnostic performance of 18 F-FDG-PET/CT for malignant pulmonary nodules...

Whole-genome sequencing (WGS)-based bioinformatics platforms for the rapid prediction of resistance will soon be implemented in the Tuberculosis (TB) laboratory, but their accuracy assessment still needs to be strengthened. Here, we fully-sequenced a total of 54 multidrug-resistant (MDR) and five susceptible TB strains and performed, for the first time, a simultaneous evaluation of the major four free online platforms (TB Profiler, PhyResSE, Mykrobe Predictor and TGS-TB). Overall, the sensitivity of resistance prediction ranged from 84...

Inability to accurately diagnose Lewy type alpha-synucleinopathy (LTS) pre-mortem has been a major obstacle to clinical care and research. Probable REM sleep behavior disorder (PRBD) diagnosed with support of instruments such as the Mayo Sleep Questionnaire (MSQ) may provide a cost effective means of predicting LTS. Since 2007, 602 subjects in the Arizona Study of Aging and Neurodegenerative Disorders had clinician assessment for PRBD (298 with, 304 without support of the MSQ), completed cognitive and movement examinations, and had neuropathological assessment...

PURPOSE: Surgical biopsy examination is the gold standard for the diagnosis of lymph node lymphomas. Fine-needle aspiration cytology (FNAC) is a quick and safe method in the management of cervical lymph nodes. Its value in confirming recurrent or residual lymphoma is well established. However, its role in the primary diagnosis of lymph node lymphoma remains controversial. The aim of this study was to assess, in our experience, the reliability of FNAC in the diagnosis of cervical lymph node lymphomas...

BACKGROUND/AIMS: This study describes the peritoneal microcirculation, compares quantitative parameters and angioarchitecture to the standard of sublingual microcirculatory assessment, and determines the practical feasibility of this method. METHODS: Incident dark field imaging was performed of the peritoneum and sublingually to determine angioarchitecture, total and perfused vessel density (TVD and PVD), the proportion of perfused vessels (PPV), the microvascular flow index (MFI) and image acquisition time...

BACKGROUND: The Neonatal Resuscitation Program (NRP) states that if adequate positive pressure ventilation (PPV) was given for a low heart rate (HR), the infant's HR should increase within the first 15 s of PPV. OBJECTIVE: To assess changes in HR in piglets with asphyxia-induced bradycardia. METHODS: Term newborn piglets (n=30) were anaesthetised, intubated, instrumented and exposed to 50 min normocapnic hypoxia followed by asphyxia. Asphyxia was achieved by clamping the tube until severe bradycardia (defined as HR at <u><</u>25% of baseline)...

BACKGROUND: Targeted quantification of protein biomarkers with liquid chromatography-tandem mass spectrometry (LC-MS/MS) has great potential, but is still in its infancy. Therefore, we elucidated the influence of charge state distribution and matrix effects on accurate quantification, illustrated by the peptide hormone hepcidin. METHODS: An LC-MS/MS assay for hepcidin, developed based on existing literature, was improved by using 5 mM ammonium formate buffer as mobile phase A and as an elution solution for solid phase extraction (SPE) to optimize the charge state distribution...
