Eczema apps conformance with clinical guidelines: a systematic assessment of functions, tools and content

Background Eczema is a prevalent complex skin condition requiring active disease monitoring and personalized education. No studies have assessed the quality of apps that aim to support eczema self‐management. Objectives To evaluate the quality and comprehensiveness of English, Chinese and Spanish self‐management eczema smartphone apps for patients and/or their caregivers. Methods A systematic assessment of eczema apps from July 2018 to November 2018. The assessment criteria were based on conformance with international eczema guidelines. The following domains were assessed: consistency and comprehensiveness of eczema‐specific educational information; quality and comprehensiveness of eczema‐specific tracking functions; compliance with health information best practice principles. Results In total, 98 apps were assessed: 82 (84%) provided educational information; 38 (39%) tracking functions; and 13 (13%) both. We found that 34% (28/82) of apps provided misleading information, particularly regarding aspects of treatment and disease progression of eczema. Only 15% (12/82) provided international guideline supported information on pharmacological therapies and 16% (13/82) on nonpharmacological therapies. Among 38 apps with a tracking function, 82% (31/38) measured specific symptoms, disease severity or current skin condition and 89% (34/38) helped users to record medication usage including application of topicals. Environmental or dietary allergens were recorded by 34% (13/38). None of the included apps complied with all criteria for educational information, tracking functions or health information principles. Conclusions Eczema apps have not yet reached their potential. The large variance in quality of eczema apps highlights the need for quality assurance mechanisms for health apps and guidance for clinicians that would enable them to make personalized recommendations for patients and caregivers

The cost of childhood atopic dermatitis in a multi-ethnic Asian population: a cost-of-illness study.

BACKGROUND: Childhood atopic dermatitis can often have a negative impact on quality of life for affected children and their caregivers. The condition contributes to increased healthcare costs and can pose heavy economic burdens on healthcare systems and societies. OBJECTIVES: The objective of this study is to provide a comprehensive estimate of the economic burden of childhood atopic dermatitis in a Singaporean sample and to investigate associated factors. METHODS: This cross-sectional cost-of-illness study applied a societal perspective. Data was collected between December 2016 and December 2017 in Singapore. Caregivers to children below 16 years of age with physician-confirmed diagnosis of atopic dermatitis were recruited and socio-demographics, clinical characteristics, health service utilisation data and time spent on caregiving were collected from all eligible participants. RESULTS: The average annual cost per child with atopic dermatitis was estimated at US$7,943 (mild US$6,651, moderate US$7,935 and severe US$14,335) in 2017 prices. The major cost was for informal caregiving (46% of the total cost) followed by out-of-pocket expenses (37%). Healthcare utilisation contributed to 17% of the total cost of which 43% was for medications. CONCLUSIONS: Childhood atopic dermatitis imposes substantial costs with a large proportion arising from informal caregiving and out-of-pocket expenses. The cost for atopic dermatitis is also strongly related to disease severity. This information is important for policymakers and other health planners when considering how to better support affected families. This article is protected by copyright. All rights reserved

Factors influencing quality of life in children with atopic dermatitis and their caregivers: a cross-sectional study

Better understanding of atopic dermatitis’ effect on quality of life could enhance current management and therapeutic strategies. Studies investigating factors related to the health-related quality of life (HRQOL) of children with atopic dermatitis and their caregivers are limited. This cross-sectional study included 559 children (<16 years) with atopic dermatitis and their caregivers. Disease severity was associated with infants’ HRQOL (moderate: IRR: 1.42, 95% CI 1.20–1.67; severe: IRR: 1.72, 95% CI 1.32–2.24). Age and disease severity were associated with children’s HRQOL (age: IRR: 0.99, 95% CI 0.98–1.00; moderate: IRR: 1.08, 95% CI 1.02–1.14). Quality of life subdomains itching/scratching, emotional distress and sleep disturbance were most reported and increased with higher disease severity. Both caregivers’ mental and physical health were negatively affected by children’s HRQOL (physical: IRR: 0.99, 95% CI 0.99–1.00; mental: IRR: 0.98, 95% CI 0.97–0.99). Sociodemographic characteristics (gender, ethnicity, educational attainment of carers, number of children) did not demonstrate significance in children’s HRQOL model. In conclusion, current atopic dermatitis diagnostics and treatment have to be extended to the factors influencing both children’ as their caregivers’ quality of life and adapting management accordingly. Itching/scratching, emotional distress and sleep disturbance deserve attention. Sociodemographic characteristics in children’s HRQOL models also merit attention in further research

Search for new phenomena in final states with an energetic jet and large missing transverse momentum in pp collisions at √ s = 8 TeV with the ATLAS detector

Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb−1 of √ s = 8 TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with pT > 120 GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between Emiss T > 150 GeV and Emiss T > 700 GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with either large extra spatial dimensions, pair production of weakly interacting dark matter candidates, or production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presente

Muon reconstruction and identification efficiency in ATLAS using the full Run 2 pp collision data set at \sqrt{s}=13 TeV

This article documents the muon reconstruction and identification efficiency obtained by the ATLAS experiment for 139 \hbox {fb}^{-1} of pp collision data at \sqrt{s}=13 TeV collected between 2015 and 2018 during Run 2 of the LHC. The increased instantaneous luminosity delivered by the LHC over this period required a reoptimisation of the criteria for the identification of prompt muons. Improved and newly developed algorithms were deployed to preserve high muon identification efficiency with a low misidentification rate and good momentum resolution. The availability of large samples of Z\rightarrow \mu \mu and J/\psi \rightarrow \mu \mu decays, and the minimisation of systematic uncertainties, allows the efficiencies of criteria for muon identification, primary vertex association, and isolation to be measured with an accuracy at the per-mille level in the bulk of the phase space, and up to the percent level in complex kinematic configurations. Excellent performance is achieved over a range of transverse momenta from 3 GeV to several hundred GeV, and across the full muon detector acceptance of |\eta |<2.7

A search for pair-produced resonances in four-jet final states at root s=13 TeV with the ATLAS detector

A search for massive coloured resonances which are pair-produced and decay into two jets is presented. The analysis uses 36.7 fb−1 − 1 of √ s = 13 TeV pp collision data recorded by the ATLAS experiment at the LHC in 2015 and 2016. No significant deviation from the background prediction is observed. Results are interpreted in a SUSY simplified model where the lightest supersymmetric particle is the top squark, ̃ t ~ , which decays promptly into two quarks through R-parity-violating couplings. Top squarks with masses in the range 100 GeV<̃<410 100 GeV < m t ~ < 410 GeV GeV are excluded at 95% confidence level. If the decay is into a b-quark and a light quark, a dedicated selection requiring two b-tags is used to exclude masses in the ranges 100 GeV<̃<470 100 GeV < m t ~ < 470 GeV GeV and 480 GeV<̃<610 480 GeV < m t ~ < 610 GeV GeV . Additional limits are set on the pair-production of massive colour-octet resonances

Search for heavy neutral Higgs bosons produced in association with b-quarks and decaying into b-quarks at root s=13 TeV with the ATLAS detector

A search for heavy neutral Higgs bosons produced in association with one or two b -quarks and decaying to b -quark pairs is presented using 27.8  fb − 1 of √ s = 13  TeV proton-proton collision data recorded by the ATLAS detector at the Large Hadron Collider during 2015 and 2016. No evidence of a signal is found. Upper limits on the heavy neutral Higgs boson production cross section times its branching ratio to b ¯ b are set, ranging from 4.0 to 0.6 pb at 95% confidence level over a Higgs boson mass range of 450 to 1400 GeV. Results are interpreted within the two-Higgs-doublet model and the minimal supersymmetric Standard Model

Measurement of single top-quark production in association with a W boson in the single-lepton channel at \sqrt{s} = 8\,\text {TeV} with the ATLAS detector

The production cross-section of a top quark in association with a W boson is measured using proton–proton collisions at \sqrt{s} = 8\,\text {TeV}. The dataset corresponds to an integrated luminosity of 20.2\,\text {fb}^{-1}, and was collected in 2012 by the ATLAS detector at the Large Hadron Collider at CERN. The analysis is performed in the single-lepton channel. Events are selected by requiring one isolated lepton (electron or muon) and at least three jets. A neural network is trained to separate the tW signal from the dominant t{\bar{t}} background. The cross-section is extracted from a binned profile maximum-likelihood fit to a two-dimensional discriminant built from the neural-network output and the invariant mass of the hadronically decaying W boson. The measured cross-section is \sigma _{tW} = 26 \pm 7\,\text {pb}, in good agreement with the Standard Model expectation

Measurements of Higgs bosons decaying to bottom quarks from vector boson fusion production with the ATLAS experiment at √=13TeV

The paper presents a measurement of the Standard Model Higgs Boson decaying to b-quark pairs in the vector boson fusion (VBF) production mode. A sample corresponding to 126 fb−1 of s√=13TeV proton–proton collision data, collected with the ATLAS experiment at the Large Hadron Collider, is analyzed utilizing an adversarial neural network for event classification. The signal strength, defined as the ratio of the measured signal yield to that predicted by the Standard Model for VBF Higgs production, is measured to be 0.95+0.38−0.36 , corresponding to an observed (expected) significance of 2.6 (2.8) standard deviations from the background only hypothesis. The results are additionally combined with an analysis of Higgs bosons decaying to b-quarks, produced via VBF in association with a photon

Measurement of Azimuthal Anisotropy of Muons from Charm and Bottom Hadrons in pp Collisions at √s = 13 TeV with the ATLAS Detector

The elliptic flow of muons from the decay of charm and bottom hadrons is measured in p p collisions at √ s = 13     TeV using a data sample with an integrated luminosity of 150     pb − 1 recorded by the ATLAS detector at the LHC. The muons from heavy-flavor decay are separated from light-hadron decay muons using momentum imbalance between the tracking and muon spectrometers. The heavy-flavor decay muons are further separated into those from charm decay and those from bottom decay using the distance-of-closest-approach to the collision vertex. The measurement is performed for muons in the transverse momentum range 4–7 GeV and pseudorapidity range | η | < 2.4 . A significant nonzero elliptic anisotropy coefficient v 2 is observed for muons from charm decays, while the v 2 value for muons from bottom decays is consistent with zero within uncertainties
