BACKGROUND: The surprise question (SQ), "Would you be surprised if this patient died within the next year?" is effective in identifying end-stage renal disease and cancer patients at high risk of death and therefore potentially unmet palliative care needs. Following implementation of the SQ in our acute care setting, we sought to explore hospital-based providers' perceptions of the tool. OBJECTIVES: To evaluate (1) providers' perceptions regarding the feasibility of SQ use in emergency and inpatient settings, (2) clinician perceptions regarding the utility of the SQ, and (3) barriers to SQ use...

BACKGROUND: Risk stratification for Wolff-Parkinson-White (WPW) pattern either by non-invasive or invasive tests is important to determine whether an ablation is necessary or not. The aim was to compare non-invasive tests and invasive studies in a pediatric WPW population. METHODS: A total of 71 WPW patients [median age 14 years (IQR 11 - 16 years); 43 male] underwent Holter monitoring, exercise stress test (EST), and transesophageal electrophysiological study (TEEPS)...

INTRODUCTION: Advances in vasectomy technique have minimized patient discomfort; however fear of pain remains a primary concern. The objective is to determine how the anticipation of pain associated with vasectomy compares with patient's actual intraoperative experienced pain levels. MATERIALS AND METHODS: A cohort of patients undergoing clinic vasectomy was analyzed. Using visual analog pain scale patients were asked to rate their anticipated pain score (APS) pre-procedure and then an experienced pain score (EPS) post-procedure...

INTRODUCTION: Intravascular volume status is an important clinical consideration in the management of the critically ill. Point-of-care ultrasonography (POCUS) has gained popularity as a non-invasive means of intravascular volume assessment via examination of the inferior vena cava (IVC). However, there are limited data comparing different acquisition techniques for IVC measurement by POCUS. The goal of this evaluation was to determine the reliability of three IVC acquisition techniques for volume assessment: sub-xiphoid transabdominal long axis (LA), transabdominal short axis (SA), and right lateral transabdominal coronal long axis (CLA) (aka "rescue view")...

INTRODUCTION: Diagnosing acute dyspnea is a critical action performed by emergency physicians (EP). It has been shown that ultrasound (US) can be incorporated into the work-up of the dyspneic patient; but there is little data demonstrating its effect on decision-making. We sought to examine the impact of a bedside, clinician-performed cardiopulmonary US protocol on the clinical impression of EPs evaluating dyspneic patients, and to measure the change in physician confidence with the leading diagnosis before and after US...

The reactor performance, granules characteristics and microbial population dynamics were investigated to assess the chronic responses of aerobic granules to zinc oxide nanoparticles (ZnO NPs) of 0, 5, 10 and 20mg/L for a period of 180days. The results showed that ZnO NPs stimulated COD removal, whereas caused inhibition to both nitrification and denitrification. However, biological phosphorus removal remained effective and stable. Introduction of ZnO NPs sharply decreased the respiration of granules, while did not change the settleability...

A membrane bioreactor (MBR), accomplishing high nitrogen removal efficiencies, was evaluated under various landfill leachate concentrations (50, 75 and 100% v/v). Proteinous and carbohydrate extracellular polymeric substances (EPS) and soluble microbial product (SMP) were strongly correlated (p<0.01) with organic load, salinity and NH4(+)-N. Exceptionally high β-glucosidase activities (6700-10,100Ug(-1)) were determined during MBR operation with 50% v/v leachate, as a result of the low organic carbon availability that extendedly induced β-glucosidases to breakdown the least biodegradable organic fraction...

AIM: Pseudomonas aeruginosa is one of the fatal biofilm forming pathogens which pose to be a problem in clinical infections, contamination of food and marine ecosystems. In this report a napthoquinone - Plumbagin has been explored for its antimicrobial (antibacterial and antibiofilm) activity against P. aeruginosa biofilm. The ability of Plumbagin to enhance the bioactivity of a known broad spectrum antibiotic was further assayed by combining the sub-MIC doses of Plumbagin with sub-MIC doses of Gentamicin against P...

The ability of Aeribacillus pallidus E334 to produce pellicle and form a biofilm was studied. Optimal biofilm formation occurred at 60 °C, pH 7.5 and 1.5% NaCl. Extra polymeric substances (EPS) were composed of proteins and eDNA (21.4 kb). E334 formed biofilm on many surfaces, but mostly preferred polypropylene and glass. Using CLSM analysis, the network-like structure of the EPS was observed. The A. pallidus biofilm had a novel eDNA content. DNaseI susceptibility (86.8% removal) of eDNA revealed its importance in mature biofilms, but the purified eDNA was resistant to DNaseI, probably due to its extended folding outside the matrix...

Biofilms are comprised of microbial cells and an extracellular polymeric substance (EPS) matrix that supports interactions between community members and with the local environment. The highly hydrated EPS matrix makes the application of many biofilm visualization techniques difficult. Hence, to better visualize how biofilms interact with their environment, there is a need for imaging techniques to monitor hydrated state biofilm dynamics. We employed an in situ dynamic approach to construct label-free images of biofilms...

Hui Chen, Ren-Cun Jin
The anaerobic ammonium oxidation (anammox) process is a promising wastewater treatment method for biological nitrogen removal. A sufficient amount of active anammox sludge as a seed is crucial to the fast establishment and stability of the anammox process. Anammox bacteria is a kind of microorganism which is sensitive to the environmental conditions, e.g., oxygen, temperature. The optimum temperature and pH for the growth of the anammox bacteria are 30-40 °C and 6.7-8.3. A proper preservation technique allows fast start-up of the anammox process, overcoming the long doubling time of anammox biomass...

Recent papers in the literature introduced a class of neural networks (NNs) with memristors, named dynamic-memristor (DM) NNs, such that the analog processing takes place in the charge-flux domain, instead of the typical current-voltage domain as it happens for Hopfield NNs and standard cellular NNs. One key advantage is that, when a steady state is reached, all currents, voltages, and power of a DM-NN drop off, whereas the memristors act as nonvolatile memories that store the processing result. Previous work in the literature addressed multistability of DM-NNs, i...

Although koi herpesvirus (KHV) has a history of causing severe economic losses in common carp and koi farms, there are still no treatments available on the market. Thus, the aim of this study was to test exopolysaccharides (EPS) for its antiviral activity against KHV, by monitoring inhibition and cytotoxic effects in common carp brain cells. These substances can be easily extracted from extracellular algae supernatant and were identified as groups of sulphated polysaccharides. In order to reach this aim, Arthrospira platensis, which is well known for its antiviral activity of intra- and extracellular compounds towards mammalian herpesviruses, was investigated as standard organism and compared to commercial antiviral drug, ganciclovir, which inhibits the viral DNA polymerization...

Peritoneal membrane failure (PMF) and, ultimately, encapsulating peritoneal sclerosis (EPS) are the most serious peritoneal dialysis (PD) complications. Combining clinical and peritoneal transport data with the measurement of molecular biomarkers, such as the chemokine CCL18, would improve the complex diagnosis and management of PMF. We measured CCL18 levels in 43 patients' effluent and serum at baseline and after 1, 2, and 3 years of PD treatment by retrospective longitudinal study, and evaluated their association with PMF/EPS development and peritoneal risk factors...

Staphylococcus epidermidis is the most frequent cause of biofilm mediated implant-associated infections. Extracellular polymeric substance (EPS) is a key component of most biofilms and in pathogens it specifically protects the entrenched-bacterial cells from antibiotics and hosts immune response, and thereby makes the infection ineradicable. Recently, the prominence of cyclic dipeptides in interfering with biofilms and the associated virulence factors of pathogens has offered an alternative to eliminate difficult-to-treat infections...
