The Relationship Between Point-of-Care Tool Use and Nurses' Self-Efficacy.

Background: Despite benefits of evidence-based practice (EBP), barriers exist that prevent translation of evidence to point of care.

Purpose: The purpose of this study was to examine types of EBP resources used by nurses, and correlate EBP resource use with nurse's self-efficacy.

Method: A descriptive correlational design was used.

The impact of household structure on disease-induced herd immunity.

The disease-induced herd immunity level [Formula: see text] is the fraction of the population that must be infected by an epidemic to ensure that a new epidemic among the remaining susceptible population is not supercritical. For a homogeneously mixing population [Formula: see text] equals the classical herd immunity level [Formula: see text], which is the fraction of the population that must be vaccinated in advance of an epidemic so that the epidemic is not supercritical. For most forms of heterogeneous mixing [Formula: see text], sometimes dramatically so.

The Availability, Appropriateness, and Integration of Services to Promote Indigenous Australian Youth Wellbeing and Mental Health: Indigenous Youth and Service Provider Perspectives.

Concerns about the complexity, fragmentation and inefficiency of Australia's current youth mental health service systems have led policy makers to seek improvements through a shift to community-based solutions. However, there is little evidence of how communities can make this shift. This paper examines the efforts of one Aboriginal and Torres Strait Islander (hereafter, respectfully, Indigenous) community-Yarrabah in north Queensland-to develop strategies for mental health and wellbeing service system improvements for school-aged youth (5-18 years).

An epidemic model with short-lived mixing groups.

Almost all epidemic models make the assumption that infection is driven by the interaction between pairs of individuals, one of whom is infectious and the other of whom is susceptible. However, in society individuals mix in groups of varying sizes, at varying times, allowing one or more infectives to be in close contact with one or more susceptible individuals at a given point in time. In this paper we study the effect of mixing groups beyond pairs on the transmission of an infectious disease in an SIR (susceptible [Formula: see text] infective [Formula: see text] recovered) model, both through a branching process approximation for the initial stages of an epidemic with few initial infectives and a functional central limit theorem for the trajectories of the numbers of infectives and susceptibles over time for epidemics with many initial infectives.

Improved management of pediatric obesity in the primary care setting through implementation of the healthy care for healthy kids obesity toolkit.

Pediatric obesity has become a major health care concern over the last several decades. This condition can lead to detrimental life-long physical and mental comorbidities. Pediatric primary care providers have a unique opportunity to both prevent and treat pediatric obesity in their clinics.

Benchmarking of Density Functionals for -Azoarene Half-Lives via Automated Transition State Search.

Molecular photoswitches use light to interconvert from a thermodynamically stable isomer into a metastable isomer. Photoswitches have been used in photopharmacology, catalysis, and molecular solar thermal (MOST) materials because of their spatiotemporal activation. Visible-light-absorbing photoswitches are especially attractive because low-energy light minimizes undesired photochemical reactions and enables biological applications.

The integrated miniaturized electrostatic analyzer: A space plasma environment sensor.

The integrated Miniaturized Electrostatic Analyzer (iMESA) was a satellite-based ionospheric sensor that operated on NASA's Space Test Program Satellite (STPSat-3) from December 2013 to July 2019. The instrument's scientific objective was to (1) measure the plasma density in low Earth orbit, (2) measure the plasma temperature in low Earth orbit, and (3) quantify the spacecraft potential with respect to the ambient plasma potential in the ionosphere. iMESA sampled the ionosphere every 10 s by measuring the ion current density through the ESA as a result of the motion of the spacecraft through the plasma.

Silicon incorporation in polymethine dyes.

Methods to red-shift fluorophores have garnered considerable interest due to the broad utility of low energy light. The incorporation of silicon into xanthene and coumarin scaffolds has resulted in an array of visible and near-infrared fluorophores. Here, we extend this approach to polymethine dyes, another popular fluorophore class, performing experimental and computational analyses.

A laminated energetic electrostatic analyzer for 0-5 keV charged particles.

A compact electrostatic energy bandpass filter based on a laminated analyzer design has been developed to measure charged particle fluxes at energies ranging from 0 to 5 keV. The sensor head has been successfully tested against a low energy magnetically filtered plasma source and an ion beam source capable of producing energetic ions in the range of 100-1250 eV. Additionally, the instrument has demonstrated the ability to accurately measure negative spacecraft frame charging using a low Earth orbit plasma simulator.

The basic reproduction number, R, in structured populations.

In this paper, we provide a straightforward approach to defining and deriving the key epidemiological quantity, the basic reproduction number, R, for Markovian epidemics in structured populations. The methodology derived is applicable to, and demonstrated on, both SIR and SIS epidemics and allows for population as well as epidemic dynamics. The approach taken is to consider the epidemic process as a multitype process by identifying and classifying the different types of infectious units along with the infections from, and the transitions between, infectious units.

Fostering Community Engagement and Acquiring Understanding of Health Needs through a Participatory Rural Appraisal in Haiti.

Background: Haiti has a population of 10 million people, and is the poorest country in the Western Hemisphere. Individuals living in rural and geographically isolated areas of Haiti are particularly vulnerable to chronic illness secondary to unmet health needs. Participatory Rural Appraisals (PRA) can be conducted to rapidly gain knowledge while empowering locals to participate in the identification and prioritization of their health needs.

Daily Drinking Is Associated with Increased Mortality.

Background: There is evidence that low-level alcohol use, drinking 1 to 2 drinks on occasion, is protective for cardiovascular disease, but increases the risk of cancer. Synthesizing the overall impact of low-level alcohol use on health is therefore complex. The objective of this paper was to examine the association between frequency of low-level drinking and mortality.

Screening for depression in young Indigenous people: building on a unique community initiative.

Gurriny Yealamucka Health Service Aboriginal Corporation (GYHSAC) is an Indigenous community-controlled health organisation providing comprehensive primary care to the people of Yarrabah in far north Queensland, Australia. GYHSAC conducts an annual Young Person's Health Check (YPC) for people aged 15-25 years based on the Medical Benefits Schedule Item 715. However, the YPC is constantly evolving to meet the needs of the community, and in 2016, in response to concerns about psychological risk among Indigenous youth, GYHSAC teamed up with James Cook University to trial an adapted PHQ-9 depression screening tool (aPHQ-9) as part of the YPC.

Exosome-Based Detection of T790M in Plasma from Non-Small Cell Lung Cancer Patients.

About 60% of non-small cell lung cancer (NSCLC) patients develop resistance to targeted epidermal growth factor receptor (EGFR) inhibitor therapy through the T790M mutation. Patients with this mutation respond well to third-generation tyrosine kinase inhibitors, but obtaining a tissue biopsy to confirm the mutation poses risks and is often not feasible. Liquid biopsies using circulating free tumor DNA (cfDNA) have emerged as a noninvasive option to detect the mutation; however, sensitivity is low as many patients have too few detectable copies in circulation.

A tutorial introduction to Bayesian inference for stochastic epidemic models using Approximate Bayesian Computation.

Likelihood-based inference for disease outbreak data can be very challenging due to the inherent dependence of the data and the fact that they are usually incomplete. In this paper we review recent Approximate Bayesian Computation (ABC) methods for the analysis of such data by fitting to them stochastic epidemic models without having to calculate the likelihood of the observed data. We consider both non-temporal and temporal-data and illustrate the methods with a number of examples featuring different models and datasets.

An exploration of the experiences of wound healing in military traumatic amputees and its impact on their rehabilitation.

The aim of this study was to establish the effect that wounds had on the rehabilitation of traumatic amputees from the military patients' perspective. In particular it established which aspects of wound healing had the greatest impact in relation to living with a wound and the effect that military cohesion had on their recovery. The study was undertaken within the interpretivistic paradigm and followed an ethnographic design using semi-structured interviews.

Robust estimation of microbial diversity in theory and in practice.

Quantifying diversity is of central importance for the study of structure, function and evolution of microbial communities. The estimation of microbial diversity has received renewed attention with the advent of large-scale metagenomic studies. Here, we consider what the diversity observed in a sample tells us about the diversity of the community being sampled.

The basic reproduction number and the probability of extinction for a dynamic epidemic model.

We consider the spread of an epidemic through a population divided into n sub-populations, in which individuals move between populations according to a Markov transition matrix Σ and infectives can only make infectious contacts with members of their current population. Expressions for the basic reproduction number, R₀, and the probability of extinction of the epidemic are derived. It is shown that in contrast to contact distribution models, the distribution of the infectious period effects both the basic reproduction number and the probability of extinction of the epidemic in the limit as the total population size N→∞.

Water mass-specificity of bacterial communities in the North Atlantic revealed by massively parallel sequencing.

Bacterial assemblages from subsurface (100 m depth), meso- (200-1000 m depth) and bathy-pelagic (below 1000 m depth) zones at 10 stations along a North Atlantic Ocean transect from 60°N to 5°S were characterized using massively parallel pyrotag sequencing of the V6 region of the 16S rRNA gene (V6 pyrotags). In a dataset of more than 830,000 pyrotags, we identified 10,780 OTUs of which 52% were singletons. The singletons accounted for less than 2% of the OTU abundance, whereas the 100 and 1000 most abundant OTUs represented 80% and 96% respectively of all recovered OTUs.

The time to extinction for a stochastic SIS-household-epidemic model.

We analyse a Markovian SIS epidemic amongst a finite population partitioned into households. Since the population is finite, the epidemic will eventually go extinct, i.e.

Effect of PCR amplicon size on assessments of clone library microbial diversity and community structure.

PCR-based surveys of microbial communities commonly use regions of the small-subunit ribosomal RNA (SSU rRNA) gene to determine taxonomic membership and estimate total diversity. Here we show that the length of the target amplicon has a significant effect on assessments of microbial richness and community membership. Using operational taxonomic unit (OTU)- and taxonomy-based tools, we compared the V6 hypervariable region of the bacterial SSU rRNA gene of three amplicon libraries of c.

Performance standards of the nerve conduction study technologist.

The primary performance standard of the nerve conduction study technologist is to perform nerve conduction studies (NCS) on patients with trauma or diseases of the peripheral nervous system. However, to be in compliance with various healthcare/medical accreditation agencies, such as Occupational Safety and Health Administration (OSHA), Centers for Disease Control and Prevention (CDC), or The Joint Commission [formerly known as the Joint Commission on Accreditation of Healthcare Organizations (JCAHO)], there are many other important performance objectives that must be met as well. It is the responsibility of the NCS technologist to meet these standards on a daily basis.

Systemic blastomycosis diagnosed by prostate needle biopsy.

A healthy 51-year-old man presented with a 1-month history of lower urinary tract irritative symptoms. Urinalysis was suggestive of infection, and the patient was treated with multiple antibiotics without relief of symptoms. A urological exam demonstrated abnormal induration of the prostate gland.

Network epidemic models with two levels of mixing.

The study of epidemics on social networks has attracted considerable attention recently. In this paper, we consider a stochastic SIR (susceptible-->infective-->removed) model for the spread of an epidemic on a finite network, having an arbitrary but specified degree distribution, in which individuals also make casual contacts, i.e.
