Acceptance factors of Zara's shopping app among fashion consumers during COVID-19

Online sales in the textile sector are undergoing a comprehensive renewal process as a result of COVID-19. This article analyzes how the pandemic has influenced the ZARA brand in its sales channel through its mobile application (app). This analysis has been carried out through the development of a UTAUT 2 model into which the constructs of Corporate Social Responsibility (CSR) and Design have been incorporated. Based on a sample of 736 Spanish people, an anonymous online questionnaire was distributed, and the responses were modeled using structural equations with Smart-PLS. From the results obtained and their interpretation, it is evident how, when purchasing textile products through the app, consumers are indifferent to the CSR of the brand, while design, ease of condition, and habit are shown as the elements that exert the greatest influence on the buyer. Despite being a growing trend within companies, the importance of CSR actions is not yet a determining factor in the intention to use fashion apps. Perhaps in a situation of uncertainty, consumers seek refuge in a well-known brand, without assessing whether the company is aligned with the interests of its environment. In times of COVID-19, users have changed their shopping habits, directly influencing online shopping. But what are the acceptance factors of these apps during this COVID-19 era? For this study, we have analyzed the ZARA fashion app through a sample of users in Spain, where the app has a higher number of active users. © 2023 John Wiley & Sons Ltd.

Facteurs prédictifs d'une poussée de psoriasis après une infection par le SARS-CoV-2 chez l'enfant

Introduction: La pandémie à SARS-CoV-2 a été source de nombreuses questions quant à l'impact de l'infection sur les dermatoses inflammatoires chroniques, et de l'impact des traitements de ces dermatoses sur la sévérité de l'infection. Le registre international Chi-PsoCov (enfants psoriasique souffrant de psoriasis et ayant développé une infection à SARS-CoV-2) a permis de montrer que les biothérapies n'augmentaient pas le risque de formes sévères de COVID-19 chez les enfants atteints de psoriasis. Par ailleurs, il était montré que le COVID-19 était responsable du développement de psoriasis de novo ou de l'aggravation d'un psoriasis connu chez certains enfants.Dans cette partie du travail nous nous sommes concentrés sur les enfants ayant développé une poussée de psoriasis après l'infection : aspects phénotypiques des poussées, et recherche de facteurs de risque liés à la maladie, au psoriasis, ou aux traitements, associés à l'aggravation du psoriasis après l'infection. Matériel et méthodes: Les données ont été collectées de février 2021 à mai 2022 en provenance de 14 pays. Les enfants étaient inclus s'ils avaient moins de 18 ans, un antécédent de psoriasis ou psoriasis apparu dans le moins suivant l'infection COVID-19, et avaient été infectés par le SARS-CoV-2 avec ou sans symptômes. Les enfants ayant développé un psoriasis de novo étaient exclus de cette étude. Résultats: Sur les 152 inclusions du registre Chi-PsoCov, dix enfants ont développé un psoriasis dans le mois suivant l'infection et n'ont pas été retenus dans ce travail. L'analyse a porté sur 135 enfants ayant développé 142 COVID-19. Le psoriasis était stable dans 120 cas (84,5 %) et s'aggravait dans le mois suivant l'infection dans 22 cas (15,5 %).Dans 20 cas, lors de la poussée, le phénotype était inchangé, et dans 2 cas, il y avait un changement de phénotype : psoriasis en plaques en psoriasis en gouttes (n = 1) ou inversé (n = 1).Ni les caractéristiques démographiques, ni les aspects du psoriasis (notamment psoriasis actif vs en rémission), ni la sévérité de l'infection à SARS-CoV-2 n'étaient associés à des poussées de psoriasis. Seule l'utilisation de traitements systémiques du psoriasis, conventionnels ou biothérapies, lors de l'infection semblait protectrice de la survenue de poussées (50,0 % dans le groupe stable vs 27,3 % dans le groupe poussées, p = 0,049). Discussion: L'infection à SARS-CoV-2 est responsable dans environ 15 % des cas de poussées de psoriasis. Dans la grande majorité des cas, le phénotype précédent l'infection est conservé. Ces poussées ne sont pas associées à la sévérité du psoriasis, de l'infection ou autres paramètre cliniques. Seuls les traitements systémiques semblent réduire ce risque, probablement en « contrôlant » la poussée. Il est possible qu'une susceptibilité d'ordre génétique, non explorée ici, explique aussi cette susceptibilité à l'infection.

COVID-19 et psoriasis de l'enfant : facteurs associés à une évolution défavorable de la COVID-19 et impact de l'infection sur le psoriasis. Registre Chi-PsoCov

Introduction: La pandémie à SARS-CoV-2 a soulevé de nombreuses questions sur la prise en charge des maladies chroniques et leurs traitements. Les données concernant l'utilisation des biothérapies chez les adultes atteints de psoriasis sont rassurantes, mais manquent chez l'enfant. Par ailleurs, l'infection à SARS-CoV-2 pourrait influencer l'évolution du psoriasis chez l'enfant. L'objectif de cette étude était d'évaluer l'impact de l'infection à SARS-CoV-2 sur le psoriasis, et la sévérité de l'infection selon le traitement systémique reçu. Matériel et méthodes: Les données ont été collectées de février 2021 à février 2022 en provenance de 14 pays. Les enfants étaient inclus s'ils avaient moins de 18 ans, un antécédent de psoriasis ou apparu dans le moins suivant l'infection COVID-19, et avaient été infectés par le SARS-CoV-2 avec ou sans symptômes. Résultats: Au total, 117 enfants ont été inclus (filles : 49,6 %, âge moyen : 12,4 ans) avec 120 infections) SARS-CoV-2. La principale forme de psoriasis était le psoriasis en plaques (69,4 %) ;le psoriasis était actif avant l'infection dans 70,1 % des cas. La majorité des enfants ne prenaient pas de traitement systémique au moment de l'infection (54,2 %), 33 enfants (28,3 %) étaient sous biothérapie (principalement anti-TNF alpha et ustékinumab), et 24 (20,0 %) sous traitement systémique conventionnel (principalement méthotrexate). L'infection était confirmée chez 106 enfants (88,3 %) et 3 ont eu la maladie 2 fois (1 enfant asymptomatique sous ustékinumab et 2 enfants symptomatiques sans traitement systémique). L'infection était symptomatique chez 75 enfants (62,5 %) avec une durée moyenne des symptômes de 6,5 jours, significativement plus longue chez les enfants sous traitement systémique conventionnel (p = 0,002) ou sans traitement systémique (p = 0,006) par rapport aux enfants traités par biothérapies. Six enfants ont nécessité une hospitalisation, dont un enfant en réanimation ;ils étaient plus fréquemment sous traitements systémiques conventionnels par rapport aux autres enfants (p = 0,01), et principalement sous méthotrexate (p = 0,03). Aucun enfant sous biothérapie n'a été hospitalisé, et aucun décès n'a été rapporté.Après l'infection, le psoriasis s'est aggravé dans 17 cas (15,2 %), sans modification du phénotype sauf pour un enfant avec un psoriasis initialement en plaques qui a eu suite à l'infection une poussée de psoriasis en gouttes. Neuf enfants (8,0 %) ont développé un psoriasis de novo dans le mois qui a suivi l'infection, plus souvent un psoriasis en gouttes (p = 0,01) par rapport aux enfants ayant un antécédent connu de psoriasis. Ces enfants avaient un antécédent familial de psoriasis dans 75,0 % des cas. Discussion: L'utilisation des biothérapies semble rassurante sans augmentation du risque de forme sévère de COVID-19 chez les enfants atteints de psoriasis. L'infection à SARS-CoV-2 était responsable du développement de psoriasis de novo ou de l'aggravation d'un psoriasis connu chez certains enfants.

SARS-COV-2 INFECTION after VACCINATION in PATIENTS with RHEUMATIC DISEASES from ARGENTINA

Background: Patients with rheumatic diseases (RD) have been excluded from SARS-CoV-2 vaccine trials. Though data appear to show safety and efficacy, mostly evidence remains in mRNA vaccines. However in our country, adenovirus and inactivated vaccines, as well as heterologous schemes are frequently used. Objectives: To describe clinical characteristics and outcomes of SARS-CoV-2 infection after vaccination in patients with RD from de the SAR-CoVAC registry and to compare them with patients who got infected before vaccination. Additionally, factors associated with COVID-19 unfavorable outcome were assessed. Methods: Adult patients with RD who have been vaccinated for SARS-CoV-2 were consecutively included between June 1st and December 21st, 2021. Con-frmed SARS-CoV-2 infection (RT-PCR o serology) was reported by the treated physician. Infection after an incomplete scheme was defned when the event was diagnosed at least 14 days after frst dose;and after a complete scheme when it occurred > 14 days after second dose. Homologous scheme is defned by two same doses of vaccine and heterologous by two different doses. Patients with previous SARS-CoV-2 infection were excluded. To compare SARS-CoV-2 infection characteristics in not vaccinated patients, subjects from the SAR-COVID registry, which includes patients with RD and SARS-CoV-2 infection, were matched 2:1 by gender, age and RD. WHO-Ordinal Scale ≥5 was used to defne unfavorable infection outcome. Descriptive statics, Chi2 test, Fischer test, T test and ANOVA were used. Results: A total of 1350 patients from the SAR COVAC registry were included, 67 (5%) presented SARS-CoV-2 infection after vaccination. The later were mostly (72%) females with a mean age of 57 (SD 15) years old. The most frequent RD were rheumatoid arthritis (41%), psoriatic arthritis (12%) and systemic lupus erythematosus (10%). At vaccination, most of them (75%) had low disease activity or remission, 19% were taking steroids, 39% methotrex-ate, 27% bDMARDs and 6% JAK inhibitors. A total of 11 (16%) patients had SARS-CoV-2 infection <14 days after the frst vaccine dose, 39 (58%) after an incomplete scheme and 17 (25 %) following a complete one. In the incomplete scheme group, 59% received Gam-COVID-Vac, 31% ChAdOx1 nCov-19 and 10% BBIBP-CorV;and in patients with complete scheme 47%, 24% and 29%, respectively. No event was reported after a complete heterologous scheme. No signifcant differences regarding sociodemoghraphic characteristics, RD, disease treatment, type of vaccine and regimen was found between in those with infection and those without it. After vaccination only 8 (12%) of the patients who got infected had an unfavorable course, 88% of them following an incomplete scheme (5 received Gam-COVID-Vac, 1 ChAdOx1 nCov-19 and 1 BBIBP-CorV) and one subject after a complete homologous Gam-COVID-Vac scheme. Having an unfavorable outcome of SARS-CoV-2 infection was associated to: male gender [63% vs 24%, p=0.036], older age [mean 70 years (SD 7) vs 55 years (SD 15), p=0.005], being Caucasian [100% vs 54%, p=0.018], higher education [mean 17 years (SD 4) vs 12 years (SD 4), p=0.010], the presence of comorbid-ities [100% vs 39%, p=0.001, having pulmonary disease [37% vs 5%, p=0.019], dyslipidemia [63% vs 17%, p=0.011] and arterial hypertension [63% vs 24%, p=0.036], RD, treatments, disease activity and types of vaccines received were comparable between groups. When comparing patients with and without vaccination prior SARS-CoV-2 infection, those who received at least one dose of vaccine had less frequently severe COVID-19 (12% vs 24%, p=0.067) and presented lower mortality due to COVID-19 (3% vs 6%, p=0.498). However these differences did not reach statistical signifcance. Conclusion: In the SAR-CoVAC registry 5% of the patients had SARS-CoV-2 infection after vaccination, most of them mild and 25% after a complete scheme. Any vaccine was associated with severe COVID-19. When comparing with non-vaccinated patients, those with at least one dose, had less frequently severe disease and died due COVID-19.

SAFETY and EFFICACY of VACCINES for SARS-COV-2 in PATIENTS with RHEUMATIC and IMMUNEMEDIATED INFLAMMATORY DISEASES: DATA from the ARGENTINEAN REGISTRY SAR-COVAC

Background: Currently there is little information on the efficacy and safety of SARS-CoV-2 vaccination in patients with immune-mediated diseases and/or under immunosuppressive treatment in our country, where different types of vaccines and mix regimens are used. For this reason, the Argentine Society of Rheumatology (SAR) with the Argentine Society of Psoriasis (SOARPSO) set out to develop a national register of patients with rheumatic and immune-mediated infammatory diseases (IMIDs) who have received a SARS-CoV-2 vaccine in order to assess their efficacy and safety in this population. Objectives: To assess SARS-CoV-2 vaccine efficacy and safety in patients with rheumatic and IMIDs. Methods: SAR-CoVAC is a national, multicenter and observational registry. Adult patients with a diagnosis of rheumatic or IMIDs who have been vaccinated for SARS-CoV-2 were consecutively included between June 1st and September 17th, 2021. Sociodemographic data, comorbidities, underlying rheumatic or IMIDs, treatments received and their modifcation prior to vaccination and history of SARS-CoV-2 infection were recorded. In addition, the date and place of vaccination, type of vaccine applied, scheme and indication will be registered. Finally, adverse events (AE), as well as SARS-CoV-2 infection after the application of the vaccine were documented Results: A total of 1234 patients were included, 79% were female, with a mean age of 57.8 (SD 14.1) years. The most frequent diseases were rheumatoid arthritis (41.2%), osteoarthritis (14.5%), psoriasis (12.7%) and spondy-loarthritis (12.3%). Most of them were in remission (28.5%) and low disease activity (41.4%). At the time of vaccination, 21% were receiving glucocorti-coid treatment, 35.7% methotrexate, 29.7% biological (b) Disease Modifying Anti-Rheumatic Drugs (DMARDs) and 5.4% JAK inhibitors. Before vaccine application 16.9% had had a SARS-CoV-2 infection. Regarding the frst dose of the vaccine, the most of the patients (51.1%) received Gam-COV-ID-Vac, followed by ChAdOx1 nCoV-19 (32.8%) and BBIBP-CorV (14.5%). In a lesser proportion, BNT162b2 (0.6%), Ad26.COV2.S (0.2%) and Coro-naVac (0.2%) vaccines were used. Almost half of them (48.8%) completed the scheme, 12.5% were mix regimenes, the most frequent being Gam-COVID-Vac/mRNA-1273. The median time between doses was 51days (IQR 53). More than a quarter (25.9%) of the patients reported at least one AE after the frst dose and 15.9% after the second. The fu-like syndrome and local hypersensitivity were the most frequent manifestations. There was one case of mild anaphylaxis. No patient was hospitalized. Altogether, the incidence of AE was 246.5 events/1000 doses. BBIBP-CorV presented signifcantly lower incidence of AE in comparison with the other types of vaccines. (118.5 events/1000 doses, p<0.002 in all cases) Regarding efficacy, 63 events of SARS-CoV-2 infection were reported after vaccination, 19% occurred before 14 days post-vaccination, 57.1% after the frst dose (>14 days) and 23.8% after the second. In most cases (85.9%) the infection was asymptomatic or had an outpatient course and 2 died due to COVID-19. Conclusion: In this national cohort of patients with rheumatic and IMIDs vaccinated for SARS-CoV-2, the most widely used vaccines were Gam-COVID-Vac and ChAdOx1 nCoV-19, approximately half completed the schedule and in most cases homologously. A quarter of the patients presented some AE, while 5.1% presented SARS-CoV-2 infection after vaccination, in most cases mild.

SAFETY of SARS-COV-2 VACCINES in PATIENTS with RHEUMATIC DISEASES: DATA from the NATIONAL REGISTRY SAR-COVAC from ARGENTINA

Background: Patients with rheumatic diseases (RD) have been excluded from SARS-CoV-2 vaccine trials, though data appear to show safety and efficacy, mostly evidence remains in mRNA vaccines. In our country, adenovirus-vector, inactivated and heterologous scheme vaccines are frequently used. Objectives: To describe the safety of SARS-CoV-2 vaccines in patients with RD from the national registry SAR-CoVAC and to assess sociodemographic and clinical factors associated to AE and disease fares after vaccination. Methods: Adult patients with RD who have been vaccinated for SARS-CoV-2 from de Argentine Society of Rheumatology Vaccine Registry (SAR-CoVAC) were consecutively included between June 1st and December 21st, 2021, This is a national multicentric observational registry that includes patients that have received at least one dose of any SARS-CoV-2 available vaccines in Argentina. Data is voluntarily collected by the treating physician. Naranjo scale was use to assess the association between the AE and vaccination. Homologous and heterologous schedules were defned according to whether both vaccines received were the same or different, respectively. Descriptive statics, Chi2 test, Fischer test, T test, ANOVA and multivariate regression logistic model were used. Results: A total of 1679 patients, with 2795 SARS-CoV-2 vaccine doses were included. Vaccines more frequently used were: Gam-COVID-Vac (1227 doses, 44%), ChAdOx1 nCov-19 (872 doses, 31%), BBIBP-CorV (482 doses, 17%) and mRAN-1273 (172 doses, 6%). Altogether, 510 EA were experienced by 449 (27%) patients. Pseudo-fu syndrome was the most frequent (11%), followed by injection site reaction (7%). They were signifcantly more frequent after the frst dose in comparison to the second one (13% vs 7% and 9% vs 5%, respectively, p<0.001 in both cases). All were mild or moderate and no patient was hospitalized due to an AE. One case of moderate anaphylaxis was reported by a patient who received Gam-COVID-Vac. No cases of vaccine-induced thrombotic thrombocytopenia were observed. There were 25 disease fares reported, 17 (68%) cases of arthritis. Among patients with two doses, those with heterol-ogous schedule presented AE more frequent after the second dose (39% vs 17%).Total incidence of EA was 182.5 events/10 00 doses, it was signifcantly lower for BBIBP-CorV (105.9 events/1000 dosis, p<0.002 for all cases). The higher incidence of AE was observed for mRAN-1273 (261.6 events/1000 doses) and ChAdOx1 nCov-19 (232.8 events/1000 doses). Patients with AE were younger [mean 55 years (SD 14) vs 59 years (SD 14), p <0.010], not Caucasian ethnicity [48% vs 35%, p<0.001], had higher education level [mean 13.8 years (SD 4) vs 11.9 years (SD 5), p<0.001], were more frequently employed [54% vs 44%, p<0.001], lived mostly in urban area [99% vs 95% p <0.001, had more frequently dyslipidemia [38% vs 28% p 0.012], and less frequently arterial hypertension [49% vs 65%, p<0.001]. Systemic lupus erythematosus [11% vs 7%, p=0.039] and Sjögren syndrome [6% vs 1.8%, p<0.001] were more frequent among them, while non infammatory diseases were less prevalent [19% vs 31%, p<0.001]. They were taking steroids [24 vs 18%, p=0.007], antimalarials [17% vs 10%, p<0.001] and methotrexate [41% vs 31%, p <0.001] more frequently. In the multivariable analysis, mRAN-1273 and ChAdOx1 nCov-19 were associated with AE, while BBIBP-CorV with lower probability of having one. (Figure 1) Conclusion: The incidence of AE was 1825 events/1000 doses, were signif-cantly higher for mRAN-1273 and ChAdOx1 nCov-19 and lower for BBIBP-CorV. Most common AE was pseudo-fu syndrome. Female sex, being younger, higher education level, ChAdOx1 nCov-19 and mRAN-1273 vaccines, the use of meth-otrexate and antimalarials were related of EA in patients with RD.

Children with psoriasis and COVID-19: factors associated with an unfavourable COVID-19 course, and the impact of infection on disease progression (Chi-PsoCov registry).

BACKGROUND: The COVID-19 pandemic has raised questions regarding the management of chronic skin diseases, especially in patients on systemic treatments. Data concerning the use of biologics in adults with psoriasis are reassuring, but data specific to children are missing. Moreover, COVID-19 could impact the course of psoriasis in children. OBJECTIVES: The aim of this study was therefore to assess the impact of COVID-19 on the psoriasis of children, and the severity of the infection in relation to systemic treatments. METHODS: We set up an international registry of paediatric psoriasis patients. Children were included if they were under 18 years of age, had a history of psoriasis, or developed it within 1 month of COVID-19 and had COVID-19 with or without symptoms. RESULTS: One hundred and twenty episodes of COVID-19 in 117 children (mean age: 12.4 years) were reported. The main clinical form of psoriasis was plaque type (69.4%). Most children were without systemic treatment (54.2%); 33 (28.3%) were on biologic therapies, and 24 (20%) on non-biologic systemic drugs. COVID-19 was confirmed in 106 children (88.3%) and 3 children had two COVID-19 infections each. COVID-19 was symptomatic for 75 children (62.5%) with a mean duration of 6.5 days, significantly longer for children on non-biologic systemic treatments (P = 0.02) and without systemic treatment (P = 0.006) when compared with children on biologics. The six children who required hospitalization were more frequently under non-biologic systemic treatment when compared with the other children (P = 0.01), and particularly under methotrexate (P = 0.03). After COVID-19, the psoriasis worsened in 17 cases (15.2%). Nine children (8%) developed a psoriasis in the month following COVID-19, mainly a guttate form (P = 0.01). DISCUSSION: Biologics appear to be safe with no increased risk of severe form of COVID-19 in children with psoriasis. COVID-19 was responsible for the development of psoriasis or the worsening of a known psoriasis for some children.
