    Allergic Rhinitis and its Impact on Asthma (ARIA) has evolved from a guideline by using the best approach to integrated care pathways using mobile technology in patients with allergic rhinitis (AR) and asthma multimorbidity. The proposed next phase of ARIA is change management, with the aim of providing an active and healthy life to patients with rhinitis and to those with asthma multimorbidity across the lifecycle irrespective of their sex or socioeconomic status to reduce health and social inequities incurred by the disease. ARIA has followed the 8-step model of Kotter to assess and implement the effect of rhinitis on asthma multimorbidity and to propose multimorbid guidelines. A second change management strategy is proposed by ARIA Phase 4 to increase self-medication and shared decision making in rhinitis and asthma multimorbidity. An innovation of ARIA has been the development and validation of information technology evidence-based tools (Mobile Airways Sentinel Network [MASK]) that can inform patient decisions on the basis of a self-care plan proposed by the health care professional.Peer reviewe

    Background: Mobile technology may help to better understand the adherence to treatment. MASK-rhinitis (Mobile Airways Sentinel NetworK for allergic rhinitis) is a patient-centred ICT system. A mobile phone app (the Allergy Diary) central to MASK is available in 22 countries. Objectives: To assess the adherence to treatment in allergic rhinitis patients using the Allergy Diary App. Methods: An observational cross-sectional study was carried out on all users who filled in the Allergy Diary from 1 January 2016 to 1 August 2017. Secondary adherence was assessed by using the modified Medication Possession Ratio (MPR) and the Proportion of days covered (PDC) approach. Results: A total of 12143 users were registered. A total of 6949 users reported at least one VAS data recording. Among them, 1887 users reported >= 7 VAS data. About 1195 subjects were included in the analysis of adherence. One hundred and thirty-six (11.28%) users were adherent (MPR >= 70% and PDC = 70% and PDC = 1.50) and 176 (14.60%) were switchers. On the other hand, 832 (69.05%) users were non-adherent to medications (MPR Conclusion and clinical relevance: Adherence to treatment is low. The relative efficacy of continuous vs on-demand treatment for allergic rhinitis symptoms is still a matter of debate. This study shows an approach for measuring retrospective adherence based on a mobile app. This also represents a novel approach for analysing medication-taking behaviour in a real-world setting.Peer reviewe

    This paper reports a study of B→K∗γB \to K^{*}\gamma decays using 62.8±0.662.8\pm 0.6 fb−1^{-1} of data collected during 2019--2020 by the Belle II experiment at the SuperKEKB e+e−e^{+}e^{-} asymmetric-energy collider, corresponding to (68.2±0.8)×106(68.2 \pm 0.8) \times 10^6 BB‟B\overline{B} events. We find 454±28454 \pm 28, 50±1050 \pm 10, 169±18169 \pm 18, and 160±17160 \pm 17 signal events in the decay modes B0→K∗0[K+π−]ÎłB^{0} \to K^{*0}[K^{+}\pi^{-}]\gamma, B0→K∗0[KS0π0]ÎłB^{0} \to K^{*0}[K^0_{\rm S}\pi^{0}]\gamma, B+→K∗+[K+π0]ÎłB^{+} \to K^{*+}[K^{+}\pi^{0}]\gamma, and B+→K∗+[K+π0]ÎłB^{+} \to K^{*+}[K^{+}\pi^{0}]\gamma, respectively. The uncertainties quoted for the signal yield are statistical only. We report the branching fractions of these decays: B[B0→K∗0[K+π−]Îł]=(4.5±0.3±0.2)×10−5,\mathcal{B} [B^{0} \to K^{*0}[K^{+}\pi^{-}]\gamma] = (4.5 \pm 0.3 \pm 0.2) \times 10^{-5}, B[B0→K∗0[KS0π0]Îł]=(4.4±0.9±0.6)×10−5,\mathcal{B} [B^{0} \to K^{*0}[K^0_{\rm S}\pi^{0}]\gamma] = (4.4 \pm 0.9 \pm 0.6) \times 10^{-5}, B[B+→K∗+[K+π0]Îł]=(5.0±0.5±0.4)×10−5, and\mathcal{B} [B^{+} \to K^{*+}[K^{+}\pi^{0}]\gamma] = (5.0 \pm 0.5 \pm 0.4)\times 10^{-5},\text{ and} B[B+→K∗+[KS0π+]Îł]=(5.4±0.6±0.4)×10−5,\mathcal{B} [B^{+} \to K^{*+}[K^0_{\rm S}\pi^{+}]\gamma] = (5.4 \pm 0.6 \pm 0.4) \times 10^{-5}, where the first uncertainty is statistical, and the second is systematic. The results are consistent with world-average values

    We present an analysis of the charmless semileptonic decay B0→π−ℓ+ΜℓB^0\to\pi^- \ell^+ \nu_{\ell}, where ℓ=e,ÎŒ\ell = e, \mu, from 198.0 million pairs of BBˉB\bar{B} mesons recorded by the Belle II detector at the SuperKEKB electron-positron collider. The decay is reconstructed without identifying the partner BB meson. The partial branching fractions are measured independently for B0→π−e+ÎœeB^0\to\pi^- e^+ \nu_{e} and B0→π−Ό+ΜΌB^0\to\pi^- \mu^+ \nu_{\mu} as functions of q2q^{2} (momentum transfer squared), using 3896 B0→π−e+ÎœeB^0\to\pi^- e^+ \nu_{e} and 5466 B0→π−Ό+ΜΌB^0\to\pi^- \mu^+ \nu_{\mu} decays. The total branching fraction is found to be (1.426±0.056±0.125)×10−4(1.426 \pm 0.056 \pm 0.125) \times 10^{-4} for B0→π−ℓ+ΜℓB^0\to\pi^- \ell^+ \nu_{\ell} decays, where the uncertainties are statistical and systematic, respectively. By fitting the measured partial branching fractions as functions of q2q^{2}, together with constraints on the nonperturbative hadronic contribution from lattice QCD calculations, the magnitude of the Cabibbo-Kobayashi-Maskawa matrix element VubV_{ub}, (3.55±0.12±0.13±0.17)×10−3(3.55 \pm 0.12 \pm 0.13 \pm 0.17) \times 10^{-3}, is extracted. Here, the first uncertainty is statistical, the second is systematic and the third is theoretical

    We report on a Belle II measurement of the branching fraction (B\mathcal{B}), longitudinal polarization fraction (fLf_L), and CP asymmetry (ACP\mathcal{A}_{CP}) of B+→ρ+ρ0B^+\to \rho^+\rho^0 decays. We reconstruct B+→ρ+(→π+π0(→γγ))ρ0(→π+π−)B^+\to \rho^+(\to \pi^+\pi^0(\to \gamma\gamma))\rho^0(\to \pi^+\pi^-) decays in a sample of SuperKEKB electron-positron collisions collected by the Belle II experiment in 2019, 2020, and 2021 at the ΄\Upsilon(4S) resonance and corresponding to 190 fb−1^{-1} of integrated luminosity. We fit the distributions of the difference between expected and observed BB candidate energy, continuum-suppression discriminant, dipion masses, and decay angles of the selected samples, to determine a signal yield of 345±31345 \pm 31 events. The signal yields are corrected for efficiencies determined from simulation and control data samples to obtain $\mathcal{B}(B^+ \to \rho^+\rho^0) = [23.2^{+\ 2.2}_{-\ 2.1} (\rm stat) \pm 2.7 (\rm syst)]\times 10^{-6},, f_L = 0.943 ^{+\ 0.035}_{-\ 0.033} (\rm stat)\pm 0.027(\rm syst),and, and \mathcal{A}_{CP}=-0.069 \pm 0.068(\rm stat) \pm 0.060 (\rm syst).Theresultsagreewithpreviousmeasurements.Thisisthefirstmeasurementof. The results agree with previous measurements. This is the first measurement of \mathcal{A}_{CP}in in B^+\to \rho^+\rho^0$ decays reported by Belle II

    Measurement of the branching fraction for the decay B→K∗(892)ℓ+ℓ−B \to K^{\ast}(892)\ell^+\ell^- at Belle II

    Full text link
    We report a measurement of the branching fraction of B→K∗(892)ℓ+ℓ−B \to K^{\ast}(892)\ell^+\ell^- decays, where ℓ+ℓ−=ÎŒ+Ό−\ell^+\ell^- = \mu^+\mu^- or e+e−e^+e^-, using electron-positron collisions recorded at an energy at or near the ΄(4S)\Upsilon(4S) mass and corresponding to an integrated luminosity of 189189 fb−1^{-1}. The data was collected during 2019--2021 by the Belle II experiment at the SuperKEKB e+e−e^{+}e^{-} asymmetric-energy collider. We reconstruct K∗(892)K^{\ast}(892) candidates in the K+π−K^+\pi^-, KS0π+K_{S}^{0}\pi^+, and K+π0K^+\pi^0 final states. The signal yields with statistical uncertainties are 22±622\pm 6, 18±618 \pm 6, and 38±938 \pm 9 for the decays B→K∗(892)ÎŒ+Ό−B \to K^{\ast}(892)\mu^+\mu^-, B→K∗(892)e+e−B \to K^{\ast}(892)e^+e^-, and B→K∗(892)ℓ+ℓ−B \to K^{\ast}(892)\ell^+\ell^-, respectively. We measure the branching fractions of these decays for the entire range of the dilepton mass, excluding the very low mass region to suppress the B→K∗(892)Îł(→e+e−)B \to K^{\ast}(892)\gamma(\to e^+e^-) background and regions compatible with decays of charmonium resonances, to be \begin{equation} {\cal B}(B \to K^{\ast}(892)\mu^+\mu^-) = (1.19 \pm 0.31 ^{+0.08}_{-0.07}) \times 10^{-6}, {\cal B}(B \to K^{\ast}(892)e^+e^-) = (1.42 \pm 0.48 \pm 0.09)\times 10^{-6}, {\cal B}(B \to K^{\ast}(892)\ell^+\ell^-) = (1.25 \pm 0.30 ^{+0.08}_{-0.07}) \times 10^{-6}, \end{equation} where the first and second uncertainties are statistical and systematic, respectively. These results, limited by sample size, are the first measurements of B→K∗(892)ℓ+ℓ−B \to K^{\ast}(892)\ell^+\ell^- branching fractions from the Belle II experiment

    Measurement of the branching fractions and CPCP asymmetries of B+→π+π0B^+ \rightarrow \pi^+ \pi^0 and B+→K+π0B^+ \rightarrow K^+ \pi^0 decays in 2019-2021 Belle II data

    Full text link
    We determine the branching fractions B{\mathcal{B}} and CPCP asymmetries ACP{\mathcal{A}_{{\it CP}}} of the decays B+→π+π0B^+ \rightarrow \pi^+ \pi^0 and B+→K+π0B^+ \rightarrow K^+ \pi^0. The results are based on a data set containing 198 million bottom-antibottom meson pairs corresponding to an integrated luminosity of 190  fb−1190\;\text{fb}^{-1} recorded by the Belle II detector in energy-asymmetric electron-positron collisions at the ΄(4S)\Upsilon (4S) resonance. We measure B(B+→π+π0)=(6.12±0.53±0.53)×10−6{\mathcal{B}(B^+ \rightarrow \pi^+ \pi^0) = (6.12 \pm 0.53 \pm 0.53)\times 10^{-6}}, B(B+→K+π0)=(14.30±0.69±0.79)×10−6{\mathcal{B}(B^+ \rightarrow K^+ \pi^0) = (14.30 \pm 0.69 \pm 0.79)\times 10^{-6}}, ACP(B+→π+π0)=−0.085±0.085±0.019{\mathcal{A}_{{\it CP}}(B^+ \rightarrow \pi^+ \pi^0) = -0.085 \pm 0.085 \pm 0.019}, and ACP(B+→K+π0)=0.014±0.047±0.010{\mathcal{A}_{{\it CP}}(B^+ \rightarrow K^+ \pi^0) = 0.014 \pm 0.047 \pm 0.010}, where the first uncertainties are statistical and the second are systematic. These results improve a previous Belle II measurement and agree with the world averages

    Correlation between work impairment, scores of rhinitis severity and asthma using the MASK-air (R) App

    Background In allergic rhinitis, a relevant outcome providing information on the effectiveness of interventions is needed. In MASK-air (Mobile Airways Sentinel Network), a visual analogue scale (VAS) for work is used as a relevant outcome. This study aimed to assess the performance of the work VAS work by comparing VAS work with other VAS measurements and symptom-medication scores obtained concurrently. Methods All consecutive MASK-air users in 23 countries from 1 June 2016 to 31 October 2018 were included (14 189 users; 205 904 days). Geolocalized users self-assessed daily symptom control using the touchscreen functionality on their smart phone to click on VAS scores (ranging from 0 to 100) for overall symptoms (global), nose, eyes, asthma and work. Two symptom-medication scores were used: the modified EAACI CSMS score and the MASK control score for rhinitis. To assess data quality, the intra-individual response variability (IRV) index was calculated. Results A strong correlation was observed between VAS work and other VAS. The highest levels for correlation with VAS work and variance explained in VAS work were found with VAS global, followed by VAS nose, eye and asthma. In comparison with VAS global, the mCSMS and MASK control score showed a lower correlation with VAS work. Results are unlikely to be explained by a low quality of data arising from repeated VAS measures. Conclusions VAS work correlates with other outcomes (VAS global, nose, eye and asthma) but less well with a symptom-medication score. VAS work should be considered as a potentially useful AR outcome in intervention studies.Peer reviewe
