PURPOSE: Some adolescent users of e-cigarettes and other electronic vaping products (EVPs) report performing "vape tricks" (exhaling aerosol to make shapes). However, little is known about this behavior. We examined the frequency of performing and watching vape tricks and the characteristics of those most likely to perform vape tricks among a sample of adolescent EVP users. METHODS: We used social media ads to recruit a national convenience sample of U.S. adolescents (n = 1,729) to participate in an online survey in September 2016...

Vincenzo Alba
In recent years entanglement measures, such as the von Neumann and the Rényi entropies, provided a unique opportunity to access elusive features of quantum many-body systems. However, extracting entanglement properties analytically, experimentally, or in numerical simulations can be a formidable task. Here, by combining the replica trick and the Jarzynski equality we devise an alternative effective out-of-equilibrium protocol for measuring the equilibrium Rényi entropies. The key idea is to perform a quench in the geometry of the replicas...

REVIEW
Seema Patel, Nithya Mathivanan, Arun Goyal
Adhesins are bacterial proteins with host cell adhesive properties. These proteins occur in diverse architectures, ranging from capsules, vesicles, pili, fimbri, to enzymes. These proteins interact with host cell surface receptor proteins, for cross-membrane- trafficking and the invasion of host cells. Thus, they lead to inflammation and pathogenesis, of chronic as well as acute type. Inhibition of adhesin-mediated immune activation can be possible by mannose supplementation, assembly disruption, and host receptor blockage, among other approaches...

This image (Figure 1) shows a glimpse of Hell (Divine Comedy), when Dante Alighieri encounters Master Adam (who, having counterfeited the Florentine money, was burned at the stake in Florence in 1281), and Sinon (who tricked the Trojans with the wooden horse filled with Achaean warriors). Master Adam, an Englishman (magistro Adam de Anglia) (1) has the shape of a lute, a rotting face, and an abdomen bloated by a disease called 'dropsy' ("…And one I saw, who like a lute were shaped / if he had only had his groin cut off / down in the region where a man is forked / The heavy dropsy which unmates the limbs / in such a way with ill-digested humor / that face and paunch no longer correspond…/ Divine Comedy, Inferno XXX, 49-54) (2)...

BACKGROUND: Trunk flexion and axial extension are characteristic symptoms of chorea-acanthocytosis (ChAc). PHENOMENOLOGY SHOWN: A 41-year-old male with ChAc (confirmed by VPS13A mutations) reported that his involuntary axial movements were significantly ameliorated by either folding his arms over his chest or putting his hands behind his head. EDUCATIONAL VALUE: These apparent "sensory tricks" suggest a dystonic pathophysiology, and also merit further study to analyze their potential for symptom control in ChAc...

The well-known aminoazoles, 3-amino-5-methylisoxazole and 5-amino-N-aryl-1H-pyrazole-4-carboxamides, were studied as an amine component in Ugi and Groebke-Blackburn-Bienaymé multicomponent reactions. The first example of an application of aminoazoles in an Ugi four-component reaction was discovered and novel features of a Groebke-Blackburn-Bienaymé cyclocondensation are established and discussed. The heterocycles obtained were evaluated for their antibacterial activity and several of them demonstrated a weak antimicrobial effect, but for most of the compounds a 30-50% increase in biomass of Gram-positive strains (mainly B...

BACKGROUND: The primary goal of treatment for open book pelvic injuries after high-energy trauma is to control haemorrhage and to close the pelvic ring anatomically. Less commonly, patients may present late with malunion or non-union. METHODS: We reviewed five operatively treated patients with delayed severe open book deformities who had a diastasis of more than 6 cm. We describe the pre-operative workup, surgical strategy and challenges experienced. They specifically include: extensive scar and contracture formation, malunion, urogenital prolapse and difficult reduction of vertical shear element...

BACKGROUND: The assessment of the work of breathing in the definitions of respiratory failure is vague and variable. OBJECTIVE: Identify a parsimonious set of signs to describe the work of breathing in hypoxemic, acutely ill patients. METHODS: We examined consecutive medical ICU patients receiving oxygen with a mask, non-invasive ventilation, or T-piece. A physician inspected each patient for 10 seconds, rated the level of respiratory distress, and then examined the patient for vital signs and 17 other physical signs...

Correcting errors based on corrective feedback is essential to successful learning. Previous studies have found that corrections to high-confidence errors are better remembered than low-confidence errors (the hypercorrection effect). The aim of this study was to investigate whether corrections to low-confidence errors can also be successfully retained in some cases. Participants completed an initial multiple-choice test consisting of control, trick and easy general-knowledge questions, rated their confidence after answering each question, and then received immediate corrective feedback...

BACKGROUND Risk adjustment is needed to fairly compare central-line-associated bloodstream infection (CLABSI) rates between hospitals. Until 2017, the Centers for Disease Control and Prevention (CDC) methodology adjusted CLABSI rates only by type of intensive care unit (ICU). The 2017 CDC models also adjust for hospital size and medical school affiliation. We hypothesized that risk adjustment would be improved by including patient demographics and comorbidities from electronically available hospital discharge codes...

Shuo Zhang, Bei Jiang, Kun Jiang, Wen-Bin Cai
Steerable hydrogen generation from the hydrogen storage chemical formic acid via heterogeneous catalysis has attracted considerable interest given the safety and efficiency concerns in handling H2. Herein, a series of carbon-supported capping-agent-free Pd nanoparticles (NPs) with mean sizes tunable from 2.0 to 5.2 nm are developed due to the demand for more efficient dehydrogenation from a formic acid-formate solution of pH 3.5 at room temperature. The trick for the facile size-controlled synthesis of Pd/C catalysts is the selective addition of Na2CO3, NH3·H2O, or NaOH to a Pd(II) solution to attain initial pH values of 7-9...

To study how people anticipate others' actions, we designed a competitive reaching task. Subjects faced each other separated by a Plexiglas screen and their finger movements in 3D space were recorded with sensors. The first subject (Attacker) was instructed to touch one of two horizontally arranged targets on the screen. The other subject (Blocker) touched the same target as quickly as possible. Average finger reaction times (fRTs) were fast, much faster than reactions to a dot moving on the screen in the same manner as the Attacker's finger...
