REVIEW
Sorin J Brull, Richard C Prielipp
PURPOSE: To narratively review published information on prevention, detection, pathophysiology, and appropriate treatment of vascular air embolism (VAE). MATERIALS AND METHODS: MEDLINE, SCOPUS, Cochrane Central Register and Google Scholar databases were searched for data published through October 2016. The Manufacturer and User Facility Device Experience (MAUDE) database was queried for "air embolism" reports (years 2011-2016). RESULTS: VAE may be introduced through disruption in the integrity of the venous circulation that occurs during insertion, maintenance, or removal of intravenous or central venous catheters...

ABSTRACT: A novel method, called a posteriori "VFM accuracy estimation" (VAE), for resolving an intrinsic VFM problem is proposed. The problem is that VFM uncertainty can easily vary according to blood flows through an echocardiographic imaged plane (i.e., "through-plane" flows), and it is unknown. Knowing the VFM uncertainty for each patient will make it possible to refine the quality of VFM-based diagnosis. In the present study, VAE was derived on the basis of an error-propagation analysis and a statistical analysis...

We described physical activity measures and hourly patterns in patients with chronic obstructive pulmonary disease (COPD) after stratification for generic and COPD-specific characteristics and, based on multiple physical activity measures, we identified clusters of patients. In total, 1001 patients with COPD (65% men; age, 67 years; forced expiratory volume in the first second [FEV1], 49% predicted) were studied cross-sectionally. Demographics, anthropometrics, lung function and clinical data were assessed...

BACKGROUND: The Centers for Disease Control and Prevention recently released a surveillance definition for respiratory complications in ventilated patients, ventilator-associated events (VAE), to replace ventilator-associated pneumonia (VAP). VAE consists of ventilator-associated conditions (VAC), infection-related ventilator-associated complications (IVAC), and possible VAP. A duration of mechanical ventilation of at least 4 d is required to diagnose VAE. However, the observed duration of mechanical ventilation was < 4 d in many previous studies...

Tumor cells have the capacity to secrete immunosuppressive substances in order to diminish dendritic cell (DC) activity and thereby escape from immune responses. The impact of mistletoe (Viscum album) extracts (VAE), which are frequently used as an additive anti-cancer therapy to stimulate the immune response, is still unknown. Using a human cellular system, the impact of two different VAE (VAEA + VAEI) on the maturation of human dendritic cells and on T cell function has been investigated using flow cytometry, automated fluorescence microscopy and cytokine bead array assays...

Deep generative adversarial networks (GANs) are the emerging technology in drug discovery and biomarker development. In our recent work, we demonstrated a proof-of-concept of implementing deep generative adversarial autoencoder (AAE) to identify new molecular fingerprints with predefined anticancer properties. Another popular generative model is the variational autoencoder (VAE), which is based on deep neural architectures. In this work, we developed an advanced AAE model for molecular feature extraction problems, and demonstrated its advantages compared to VAE in terms of (a) adjustability in generating molecular fingerprints; (b) capacity of processing very large molecular data sets; and (c) efficiency in unsupervised pretraining for regression model...

PURPOSE: To present the Tomographic and Biomechanical Index (TBI), which combines Scheimpflugbased corneal tomography and biomechanics for enhancing ectasia detection. METHODS: Patients from different continents were retrospectively studied. The normal group included 1 eye randomly selected from 480 patients with normal corneas and the keratoconus group included 1 eye randomly selected from 204 patients with keratoconus. There were two groups: 72 ectatic eyes with no surgery from 94 patients with very asymmetric ectasia (VAE-E group) and the fellow eyes of these patients with normal topography (VAE-NT group)...

BACKGROUND: Forced expiratory volume in 1 s over height cubed (FEV1/Ht(3)) is an FEV1 expression that uses no reference values and is independently associated with adverse outcomes in older adults. No studies have reported on the prognostic value of its decline over time in adults aged 80 and over. AIM: To investigate the prognostic value of FEV1/Ht(3) decline for adverse outcomes in a cohort of adults aged 80 and over. METHODS: 328 community-dwelling adults aged 80 and over of the BELFRAIL prospective cohort had two valid FEV1 measurements as part of their comprehensive geriatric assessment at baseline and follow-up (after 1...

AIMS: To assess factors associated with Prolonged Inaction (PI) in insulin-naïve patients with Type 2 Diabetes Mellitus (T2DM). PI was defined as the absence of treatment initiation or intensification for ≥12 months despite HbA1c >7% (53mmol/mol). METHODS: A retrospective cohort study was conducted based on data from Intego, a Flemish General Practice registry. The study period ranged from January 1, 2006 to December 31, 2013. Patients with insulin therapy before the start of the study period were excluded from the analysis...

INTRODUCTION: Management of complex cysts and benign intraductal/intracystic masses is controversial. The aim of this study was to determine if the complete removal of the complex cyst lesions with ultrasound-guided vacuum-assisted excision (US-VAE) is sufficient for their safe management when the histological diagnosis obtained at biopsy is benign. SUBJECTS AND METHODS: This is a single institution retrospective study performed on patients who underwent breast biopsy between April 2007 and September 2013...

Background: adults aged 80 and over, a fast growing age-group, with increased co-morbidity and frailty have not been the focus of previous research on dyspnoea. We investigate the correlates of dyspnoea and its association with adverse outcomes in a cohort of adults aged 80 and over. Methods: about 565 community-dwelling adults aged 80 and over of the BELFRAIL prospective cohort had assessment of Medical Research Council dyspnoea scale (MRC), forced expiratory volume in 1 s (FEV1), N-terminal pro-brain natriuretic peptide (NT-proBNP), physical performance tests, grip strength, 15 items geriatric depression scale, activities of daily living (ADL), body mass index (BMI) and demographics data...

The potential years of life lost (PYLL) observed in a cohort of cancer patients cannot be fully assigned to the cancer as both cancer-related and non-cancer-related deaths contribute. A method is presented to decompose the observed all-cause PYLL into cancer mortality and population background mortality fractions when cause of death information is not available. Furthermore, the association of cancer-specific PYLL with cancer-specific mortality and mean age at diagnosis is explored and the impact of the follow-up window length is examined...

OBJECTIVES: The National Healthcare Safety Network (NHSN) replaced its old definition for ventilator associated pneumonia (VAP) with ventilator associated events (VAEs) in 2013. Little data is available comparing the two definitions in burn patients. METHODS: Data from 2011-2014 were collected on burn patients mechanically ventilated for at least two days. VAP was determined using two methods: (1) pneumonia as defined by the previous more clinical CDC (NHSN) definition captured in the burn registry; (2) pneumonia as defined by the recent CDC (NHSN) standard of Ventilator-Associated Events where patients meeting the criteria for possible VAP (PVAP) were considered having a pneumonia...

BACKGROUND: Evidence is lacking concerning the effect of additional trunk rehabilitation on gait performance. Investigating gait performance by both clinical and biomechanical outcome measures might lead to new scientific insights into the importance of the trunk during gait rehabilitation in people suffering from stroke. This protocol was written according to the SPIRIT 2013 Statement. METHODS AND DESIGN: An assessor-blinded randomized controlled trial will be conducted in patients with impaired trunk control after stroke...

BACKGROUND: In 2013, the Centers for Disease Control and Prevention (CDC) developed new surveillance definitions for ventilator-associated events (VAE), leading to concerns that hospitals may be underreporting the true incidence of ventilator-associated pneumonias (VAPs). We sought to compare rates of clinically diagnosed VAP with CDC defined possible VAPs (PVAPs) in patients with a VAE in the surgical/trauma intensive care unit (STICU). HYPOTHESIS: Significant difference exists between rates of clinical VAP and PVAP in patients with at least one VAE...

Vascular adverse events (VAE) are an emerging problem in patients with chronic myeloid leukemia (CML) receiving second-generation BCR-ABL1 tyrosine kinase inhibitors (TKI). Relevant VAE comprise peripheral, cerebral, and coronary artery changes in patients receiving nilotinib, venous and arterial occlusive events during ponatinib therapy, and pulmonary hypertension in patients receiving dasatinib. Although each TKI binds to a unique profile of molecular targets in leukemic cells and vascular cells, the exact etiology of drug-induced vasculopathies remains uncertain...

BACKGROUND: Promoter methylation of N-myc Downstream-Regulated Gene 4 (NDRG4) in fecal DNA is an established early detection marker for colorectal cancer (CRC). Despite its connection to CRC, NDRG4 is predominantly studied in brain and heart, with little to no knowledge about its expression or role in other organs. In this study, we aimed to determine the whole-body expression of NDRG4, with a focus on the intestinal tract. METHODS: We investigated NDRG4 expression throughout the body by immunohistochemistry, Western Blotting and in situ mRNA hybridization using tissues from NDRG4 wild-type, heterozygous and knockout mice and humans...

Venous air embolism (VAE) is a well-known complication of sitting position neurosurgery which most characteristically manifests as mild to severe hemodynamic alterations. Development of pulmonary edema is a known, though infrequent, manifestation of VAE. We report here the occurrence of acute pulmonary edema without accompanying hemodynamic changes in a patient undergoing retromastoid craniotomy and tumor decompression in the sitting position. The patient required supportive treatment and elective ventilation for 11 days before the edema resolved...
