The OLAP tools developed in this context are further enriched by machine learning procedures that magnify the mining effect. The contribution presented in this paper also embeds an implicit methodology for OLAP over big COVID-19 data. Experimental analysis on the target case study is also provided.

Using parameters of piecewise approximation by exponents for epidemiological time series data analysis

Nowadays, detailed epidemiological data are available in the form of time series data. Theoretically, those data can be adequately described by different dynamic models containing exponential growth and exponential decay elements. Practically, parameters of those models are not constants - they can change in time because of many factors like changing hygiene policies, changing social behavior and vaccination. Hence, it was decided to use a piecewise approach: short sequential fragments of time series data are approximated by a function containing some parameters. Analysis of synthetic and real-life Coronavirus disease 2019 data demonstrates that the proposed approach can be used to evaluate the validity of mathematical epidemiological models under test for the different periods of time. More real-life data from different countries must be analyzed in order to recommend an optimal set of the smoothing parameters, and to evaluate the reliability of the proposed approach for the analysis of real-life data. © ISTE Ltd 2022.

Mortality among inpatients with bipolar disorders and COVID-19: a propensity score matching analysis in a national French cohort study.

BACKGROUND: It remains unknown whether coronavirus disease 2019 (COVID-19) patients with bipolar disorders (BDs) are at an increased risk of mortality. We aimed to establish whether health outcomes and care differed between patients infected with COVID-19 with BD and patients without a diagnosis of severe mental illness. METHODS: We conducted a population-based cohort study of all patients with identified COVID-19 and respiratory symptoms who were hospitalized in France between February and June 2020. The outcomes were in-hospital mortality and intensive care unit (ICU) admission. We used propensity score matching to control for confounding factors. RESULTS: In total, 50 407 patients were included, of whom 480 were patients with BD. Patients with BD were 2 years older, more frequently women and had more comorbidities than controls without a diagnosis of severe mental illness. Patients with BD had an increased in-hospital mortality rate (26.6% v. 21.9%; p = 0.034) and similar ICU admission rate (27.9% v. 28.4%, p = 0.799), as confirmed by propensity analysis [odds ratio, 95% confidence interval (OR, 95% CI) for mortality: 1.30 (1.16-1.45), p < 0.0001]. Significant interactions between BD and age and between BD and social deprivation were found, highlighting that the most important inequalities in mortality were observed in the youngest [OR, 95% CI 2.28 (1.18-4.41), p = 0.0015] and most deprived patients with BD [OR, 95% CI 1.60 (1.33-1.92), p < 0.001]. CONCLUSIONS: COVID-19 patients with BD were at an increased risk of mortality, which was exacerbated in the youngest and most deprived patients with BD. Patients with BD should thus be targeted as a high-risk population for severe forms of COVID-19, requiring enhanced preventive and disease management strategies.

Use of Remdesivir in Patients with SARS-CoV-2 Pneumonia in a Real-Life Setting during the Second and Third COVID-19 Epidemic Waves.

In this retrospective comparative study, we evaluated the effectiveness of remdesivir (RDSV) in patients with SARS-CoV-2 pneumonia. Individuals hospitalized between March 2020 and August 2022 at S.M. Goretti Hospital, Latina, with a positive test for SARS-CoV-2 and, concomitantly, pneumonia, were included. The overall survival was the primary endpoint. The composite secondary endpoint included death or progression in severe ARDS at 40 days. The study population was stratified according to treatment into two groups: the RDSV group (patients treated with RDSV-based regimens) and the no-RDSV group (patients treated with any other, not RDSV-based, regimens). Factors associated with death and progression to severe ARDS or death were assessed by multivariable analysis. A total of 1153 patients (632 belonging to the RDSV group and 521 to the no-RDSV group) were studied. The groups were comparable in terms of sex, PaO2/FiO2 at admission, and duration of symptoms before hospitalization. Further, 54 patients (8.5%) in the RDSV group and 113 (21.7%) in the no-RDSV group (p < 0.001) died. RDSV was associated with a significantly reduced hazard ratio (HR) of death (HR, 0.69 [95% CI, 0.49-0.97]; p = 0.03), compared to the no-RDSV group, as well as a significantly reduced OR of progression in severe ARDS or death (OR, 0.70 [95% CI 0.49-0.98]; p = 0.04). An overall significantly higher survival rate was observed in the RDSV group (p < 0.001, by log-rank test). These findings reinforce the survival benefit of RDSV and support its routine clinical use for the treatment of COVID-19 patients.

Real-world experience of rituximab biosimilar GP2013 in rheumatoid arthritis patients naïve to or switched from reference rituximab.

Randomized controlled trials showed high comparability of biosimilar rituximab (bs-RTX) GP2013 to biologic originator RTX (bo-RTX). Data on effectiveness of switching from bo-RTX to bs-RTX, starting therapy with bs-RTX, and bs-RTX drug survival in real-world setting are sparse. To explore long-term drug effectiveness and survival of bs-RTX GP2013 in rheumatoid arthritis (RA) patients both naïve to and mandatory switched from bo-RTX, and to clarify reasons for treatment cessation. Retrospective observational cohort study including RA outpatient clinic patients treated with bs-RTX between 2018 and 2021 in Norway. Patients were examined and monitored using recommended measures for disease activity and patient-reported outcomes (PROs). For description of population medians and interquartile range were used. Difference between observation times was assessed with Signed-Rank test, drug survival with Kaplan-Meier survival analysis. Reasons for discontinuation were ascertained. Among 110 patients, at baseline, 88 were mandatory switched from bo-RTX and 22 were RTX-naïve. During 2-year follow-up, disease activity and PROs measures remained stable in switchers subgroup and improved in subgroup starting bs-RTX for the first time. Overall drug survival was 80.0% after 1 year and 57.7% after 2 years and was significantly higher in bs-RTX-switched than in bs-RTX-naïve patients (p = 0.036). Two most frequently reported reasons for drug discontinuation were remission (38.6%) and doctor's decision (27.1%). RA patients treated with bs-RTX had satisfactory treatment response and drug retention rates which supports equivalence of bs-RTX GP2013 to bo-RTX, both in patients naïve to and mandatory switched from bo-RTX.

Research strategies in treatment of hypertension: value of retrospective real-life data.

This review will discuss the limitations of data collected by RCTs in relation to their applicability to daily life clinical management. It will then argue that these limitations are only partially overcome by modifications of RCT design and conduction (e.g. 'pragmatic trials') while being substantially attenuated by real-life-derived research, which can fill many gaps left by trial-collected evidence and have thus an important complementary value. The focus will be on the real-life research approach based on the retrospective analysis of the now widely available healthcare utilization databases (formerly known as administrative databases), which will be discussed in detail for their multiple advantages as well as challenges. Emphasis will be given to the potential of these databases to provide low-cost information over long periods on many different healthcare issues, drug therapies in particular, from the general population to clinically important subgroups, including (i) prognostic aspects of treatments implemented at the medical practice level via hospitalization and fatality data and (ii) medical practice-related phenomena such as low treatment adherence and therapeutic inertia (unsatisfactorily evaluated by RCTs). It will also be mentioned that thanks to the current availability of these data in electronic format, results can be obtained quickly, helping timely decisions under emergencies. The potential shortcomings of this approach (confounding by indication, misclassification, and selection bias) will also be discussed along with their possible minimization by suitable analytic means. Finally, examples of the contributions of studies on hypertension and other cardiovascular risk factors will be offered based on retrospective healthcare utilization databases that have provided information on real-life cardiovascular treatments unavailable via RCTs.

Adalimumab, Ustekinumab, and Secukinumab in the Management of Hidradenitis Suppurativa: A Review of the Real-Life Experience.

To date, adalimumab (ADA) is the only biotechnology drug approved for the management of hidradenitis suppurativa (HS), an inflammatory skin condition. However, it quickly became apparent that the efficacy of adalimumab in daily practice was highly variable. In our review, we highlighted the current evidence from literature on the use of biologics in HS in a real-life setting, particularly adalimumab, secukinumab and ustekinumab. Data on the effectiveness and safety of biologic drugs in HS management have been analyzed. Even if the results are promising, more studies are needed. In our opinion, the armamentarium of drugs for HS management is increasing, and treatment will be based on a tailored-tail approach, minimizing the risk of adverse events. In this context, we want to point out the reported effectiveness and safety data concerning adalimumab, ustekinumab and secukinumab as well as ixekizumab.

Long-COVID in Patients with Cancer Previously Treated with Early Anti-SARS-CoV-2 Therapies in an Out-of-Hospital Setting: A Single-Center Experience.

The incidence of long COVID in a cohort of patients with cancer with or without previous treatment with early therapies anti-SARS-CoV-2 in an out-of-hospital setting have to be elucidated. We prospectively enrolled all patients treated for a solid tumor at the department of Medical Oncology of the Fondazione IRCCS Policlinico San Matteo with a positive SARS-CoV-2 antigen or polymerase chain reaction test from January to September 2022 (Omicron surge). Ninety-seven patients answered the survey questions by telephone at least 12 weeks after COVID-19 diagnosis in order to evaluate the incidence of long COVID symptoms. Only twelve patients (12.4%) reported long COVID. No significant difference between early therapies anti-SARS-CoV-2 31 and long COVID (p = 0.443) was seen. The female sex (p = 0.024) and diabetes mellitus (p = 0.014) are significantly associated with long COVID. No statistically significant difference between the two groups (Long COVID vs. No Long COVID) according to the time to nasal swab viral clearance (p = 0.078). The overlap between the symptoms related to the oncological disease/oncological treatment and the symptoms of long COVID is one of the main future challenges that oncologists will have to manage.

Real-Life Effectiveness and Safety of Upadacitinib in Adults and Adolescents with Moderate-to-Severe Atopic Dermatitis: A Single-Center 16-Week Study.

INTRODUCTION: The treatment of severe atopic dermatitis (AD) includes cyclosporine and recently approved biologics and small molecules. Among these, upadacitinib is a selective inhibitor of Janus kinase 1, approved for the treatment of severe AD in adolescents/adults. Upadacitinib has shown efficacy and safety in several phase 3 clinical trials, but data on real-life patients are still lacking. METHODS: We conducted a retrospective real-life observational study to evaluate the effectiveness and safety of upadacitinib up to week 16 in a cohort of both bio-naïve and bio-experienced patients. This study was carried out by analyzing the AD database records of an Italian referral hospital. Thirty-eight patients were included in this study, and 35 completed 16 weeks of treatment. RESULTS: At week 16, out of 35 patients, the percentages of Eczema Area and Severity Index (EASI) 50, EASI 75, EASI 90 and EASI 100 responses were 94.29, 91.43, 74.29, and 60%, respectively. A decrease of at least 4 points from baseline of itch-NRS was reported by 94.74 and 91.43% of patients at weeks 8 and 16. Regarding the safety of upadacitinib, 26.32% of patients experienced at least one adverse event (AE), and a total of 13 AEs were recorded, including blood test abnormalities and papulopustular acne. None of our patients interrupted the drug because of an AE. CONCLUSIONS: We observed higher rates of EASI75/EASI90/EASI100 responses at week 16, compared with data from clinical trials. The safety profile of upadacitinib was favorable, as no AEs leading to discontinuation were experienced by our patients up to week 16.

Dataset of virtual and real-life visual experiences inside a museum: survey on visual perception with objective and subjective measures.

Occupants' perception of a space depends on their experience [1], [2], [3]. Four kinds of visiting experiences were carried out inside the Natural History Museum of the University of Pisa [4]. The museum is housed, together with the National Museum of the Charterhouse [5], inside the Monumental Charterhouse of Calci, near Pisa. Four of the permanent exhibition halls of the Museum were selected for the survey: Historical Gallery, Mammal's Hall, Ungulates' Gallery and Cetaceans' Gallery. A total of 117 participants were divided into four groups depending on their visiting experience: real-life, or virtual based respectively on videos, photos or computer-generated photorealistic images (renders). Experiences are compared. The comparison comprehends objective data (measured illuminance levels) and subjective data (questionnaire outcomes on the perception of the space). The illuminance levels were measured using a photoradiometer: datalogger Delta Ohm HD2102.2 equipped with LP 471 PHOT probe. The probe was placed 1.20 m above floor level, and it was set to measure vertical illuminance at 10 seconds intervals. To evaluate participants' perception of the space questionnaires were used. The presented data refer to the article: "Perception of light in museum environments: comparison between real-life and virtual visual experiences" [1]. This kind of data provides a base to assess if virtual kinds of experience can be implemented in museum environments as an alternative to the real-life experience, and to understand if such an implementation is detrimental or not in terms of participants' perception of the space. Virtual experiences can be particularly useful for spreading culture, making it accessible even in presence of moving restrictions for people, such as those in force today due to the SARS-CoV-2 emergency.

Real-life effectiveness of COVID-19 vaccine during the Omicron variant-dominant pandemic: how many booster doses do we need?

The surge in coronavirus disease 2019 (COVID-19) caused by the Omicron variants of the severe acute respiratory syndrome coronavirus 2 necessitates researches to inform vaccine effectiveness (VE) and other preventive measures to halt the pandemic. A test-negative case-control study was conducted among adults (age ≥18 years) who were at-risk for COVID-19 and presented for nasopharyngeal real-time polymerase chain reaction testing during the Omicron variant-dominant period in Thailand (1 January 2022-15 June 2022). All participants were prospectively followed up for COVID-19 development for 14 days after the enrolment. Vaccine effectiveness was estimated and adjusted for characteristics associated with COVID-19. Of the 7971 included individuals, there were 3104 cases and 4867 controls. The adjusted VE among persons receiving 2-dose, 3-dose, and 4-dose vaccine regimens for preventing infection and preventing moderate-to-critical diseases were 33%, 48%, 62% and 60%, 74%, 76%, respectively. The VE were generally higher among those receiving the last dose of vaccine within 90 days compared to those receiving the last dose more than 90 days prior to the enrolment. The highest VE were observed in individuals receiving the 4-dose regimen, CoronaVac-CoronaVac-ChAdOx1 nCoV-19-BNT162b2 for both preventing infection (65%) and preventing moderate-to-critical diseases (82%). Our study demonstrated increased VE along with an increase in number of vaccine doses received. Current vaccination programmes should focus on reducing COVID-19 severity and mandate at least one booster dose. The heterologous boosters with viral vector and mRNA vaccines were highly effective and can be used in individuals who previously received the primary series of inactivated vaccine.

Using Padlet as a Learning Space for Simulating Real-Life Business Communication

Due to the Covid-19 pandemic, lecturers of higher learning institutions had to pivot quickly from face-to-face classes to online classes. The new normal of online teaching and learning challenged lecturers in keeping their students engaged, especially when teaching a language course that heavily focuses on the writing component. The purpose of this study was to examine students' perception of using Padlet as a learning space to simulate real-life business communication. At the end of a 14-week semester language course, a cohort of 38 diploma students responded to a self-administered online survey with a 79% response rate. Findings from the descriptive analysis indicated high mean values for most survey items measured, implying that the students were generally favourable towards the use of Padlet and the simulation approach in learning business communication. Curriculum designers and lecturers of other courses could consider the potential of using Padlet as a learning space for simulation. Recommendations, limitations, and future research directions are also discussed in this paper. © 2022 Editorial Board TESL - EJ. All rights reserved.

Differential clinical characteristics and performance of home antigen tests between parents and children after household transmission of SARS-CoV-2 during the Omicron variant pandemic.

OBJECTIVES: The SARS-CoV-2 Omicron variant pandemic struck Taiwan in April 2022. Rapid antigen tests (RATs) play an important role in providing rapid results during a pandemic. However, self-collected samples by the children's caregivers without the supervision of medical personnel raise some concerns. METHODS: This study was performed to investigate household transmission, clinical characteristics, and antigen performance in a special COVID-19 family clinic in a children's hospital. The performance of at-home RATs was evaluated based on reverse transcription-polymerase chain reaction. RESULTS: We included 627 patients in our study between May 11 and June 10, 2022. The COVID-19 full vaccination rate was significantly higher in adults (98.5%) than in children (5.9%, P <0.001). The transmission rate was significantly higher in children (91.3%) than in adults (76.6%, P <0.001). Infected children had more incidents of fever (82.4% vs 22.4%, P <0.001) and a higher peak fever than adults. Based on the reverse transcription-polymerase chain reaction, the negative predictive rate of the home RAT was only 38.7% (95% confidence interval: 31.9-46.0%) in children. The cycle threshold value of those with false-negative antigen tests was significantly lower in children. CONCLUSION: Children had a higher transmission rate, more fever, and higher peak fever than adults. Home RAT has a suboptimal negative predictive rate in children.

Efficacy and safety of belantamab-mafodotin in triple-refractory multiple myeloma patients: A multicentric real-life experience.

Belantamab-mafodotin is an innovative and selective treatment for multi-refractory/relapsed multiple myeloma (MM) patients; however, available real-life experiences on efficacy and safety are limited. In this real-world multicentric retrospective study, we enrolled 28 MM patients treated in four Hematology units of Campania region, Italy, who received a median of six treatment lines prior to belantamab-mafodotin. The overall response rate (ORR) was 40% (complete remission, CR, 11%; very good partial remission, VGPR, 11%; and partial remission, PR, 18%), with a median progression-free survival (PFS) and overall survival (OS) of 3 and 8 months, respectively. One of the most frequent drug-related adverse events was keratopathy observed in nine (32%) patients, leading to therapy discontinuation in only three (11%) of them. Moreover, 22 out of 28 total patients who were treated with at least two administrations achieved an ORR of 50% (CR, 14%; VGPR, 14%; and PR, 22%) with a median PFS and OS of 5 and 11 months, respectively. In conclusion, our multicentric study confirmed efficacy and safety of belantamab-mafodotin in triple-refractory MM patients even in the real-life setting.

Real life experience of molnupiravir as a treatment of SARS-CoV-2 infection in vaccinated and unvaccinated patients: a letter on its effectiveness at preventing hospitalization.

BACKGROUND: The SARS-CoV-2 pandemic has prompted clinicians to develop an early and effective treatment of viral infections. To date, vaccines, monoclonal antibodies, and antivirals are the cornerstone of therapy for SARS-CoV-2. AIFA approved the prescription of molnupiravir on 30/12/2021. Molnupiravir is a prodrug that causes the accumulation of errors in the viral genome. METHODS: We prescribed molnupiravir to a total of 74 patients in a range between 26 and 96 years old and followed-up them for 30 days. 10 patients affected by idiopathic pulmonary fibrosis (IPF) were treated. RESULTS: The follow-up showed that all of the treated patients presented a regression of symptoms. No patients were hospitalized and/or showed sequelae after the infection by SARS-CoV-2, even though the examined population was older and with more co-morbidities than other patients treated with different antivirals. CONCLUSION: Molnupiravir is safe and well-tolerated by patients with high-risk of progression to severe COVID. No patients were hospitalized or showed sequelae, including all patients affected by IPF.

Effectiveness of the available early therapies in reducing severe COVID-19 in non-hospitalized patients with solid tumors on active treatment.

Emergency use authorization of drugs against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by regulatory authorities has provided new options to treat high-risk outpatients with mild-to-moderate Coronavirus disease 2019 (COVID-19). We conducted an ambispective cohort study of patients with solid tumors on active treatment to examine the effectiveness of these drugs in preventing the progression to severe COVID-19. Sixty-nine patients with solid tumors (43 women, 26 men; median age 61, range 26-80) reported a laboratory-confirmed diagnosis of SARS-CoV-2 infection. Forty-nine patients received early therapy. Only one patient (14.5%) required hospitalization for COVID-19. As for safety, two patients (5.9%) reported nausea during nirmatrelvir/ritonavir. The majority of treated patients showed a reduced time to negative sample (73 vs. 18%, p = 0.0011) and shorter symptoms' duration (94 vs. 27%; p < 0.0001) compared to the patients not treated with the early COVID-19 therapies. Our data suggest that early therapies may reduce the morbidity of COVID-19 in patients with solid tumors.

Monoclonal Antibodies against SARS-CoV-2 Infection: Results from a Real-Life Study before the Omicron Surge.

Despite the lightning-fast advances in the management of SARS-CoV after 2 years of pandemic, COVID-19 continues to pose a challenge for fragile patients, who could benefit from early administration of monoclonal antibodies (mAbs) to reduce the risk of severe disease progression. We conducted a prospective study to evaluate the effectiveness of mAbs against SARS-CoV-2 among patients at risk for severe disease progression, namely elderly and those with comorbidities, before the omicron variant surge. Patients were treated with either casirivimab/imdevimab, sotrovimab, or bamlanivimab/etesevimab. The rates and risk factors for clinical worsening, hospitalization, ICU admission and death (unfavorable outcomes) were evaluated. A stratified analysis according to the presence of SARS-CoV-2 IgG was also performed. Among 185 included patients, we showed low rates of unfavorable outcomes (9.2%), which were more frequent in patients with chronic kidney disease (aOR: 10.44, 95% CI: 1.73-63.03; p < 0.05) and basal D-dimer serum concentrations > 600 ng/mL (aOR 21.74, 95% CI: 1.18-397.70; p < 0.05). Patients with negative SARS-CoV-2 serology at baseline showed higher C-reactive protein values compared with patients with positive serology (p < 0.05) and a trend toward a higher admission rate to SICU and ICU compared with patients with positive serology. Our results thus showed, in a real-life setting, the efficacy of mAbs against SARS-CoV-2 before an Omicron surge when the available mabs become not effective.

Lost in Translation: Evaluation of Subcutaneous Interferon-ß Treatment for SARS-CoV-2 Infection in Real Life.

Despite in vitro activity of interferon-ß (IFN-ß) against SARS-CoV-2 infection, its clinical efficacy remains controversial. We evaluated the impact of IFN-ß treatment in a cohort of 3590 patients hospitalized with COVID-19 during March−April 2020. The primary endpoint was a composed variable of admission to intensive care unit (ICU)/death. Overall, 153 patients (4%) received IFN-ß. They were significantly more severely ill, with a worse clinical and analytical situation, explaining a higher ICU admission (30% vs. 17%; p < 0.01), and a shorter time to the composed variable. In a Cox regression analysis, older age, lymphopenia, renal failure, or increased neutrophil-to-lymphocyte ratio were associated with a greater hazard ratio (HR) of admission at ICU/death. Notably, the HR of IFN-ß for the outcome variable was no longer significant after adjustment (HR, 1.03; 95% CI, 0.82−1.30), and different sensitivity analysis (early IFN use, ICU admission) showed no changes in the estimates. A propensity score matching analysis showed no association of IFN-ß therapy and outcome. In conclusion, in this large cohort of hospitalized COVID-19 patients, IFN-ß was used mainly in patients with advanced disease, reflecting an important bias of selection. After adjusting by severity, IFN-ß was not associated with a higher rate of ICU admission or mortality.

Real-life experience of tofacitinib in patients with treatment-resistant rheumatoid arthritis: A 5-year follow-up: Monocentric experience.

OBJECTIVE: The present study aims to assess the short- and long-term effects of tofacitinib (TOFA) therapy on efficacy, safety, and drug retention rate patients with rheumatoid arthritis (RA) refractory to conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) and/or biological disease-modifying anti-rheumatic drugs (bDMARDs). METHODS: Thirty-five patients with RA who received TOFA therapy for at least 3 months in rheumatology outpatient clinic between December 2015 and December 2020 were included in the study. The prospectively follow-up results of the patients obtained on the 6th month and 5th year are presented. Demographic characteristics of the patients, the disease activity score-28 for RA with erythrocyte sedimentation rate (DAS 28-4 [ESR]), change in DAS-28, health assessment questionnaire score, patient visual analog scale score, and laboratory parameters were recorded. The data at 6 months and 5 years of treatment were compared with baseline data. All side effects were recorded at each follow-up visit. Wilcoxon signed-rank tests were used for analysis. RESULTS: Of the 35 patients, 23 received TOFA treatment after receiving ≥1 bDMARDs, while the remaining 12 patients received TOFA therapy were biologic naive. On the 6-month follow-up, DAS 28-4 (ESR) score and DAS28 improvement significantly decreased at the 6th months from baseline (p<0.001 and p<0.001, respectively), and moderate disease activity was achieved in 13 patients. High disease activity persisted in four patients. DAS28 improvement according to the EULAR response criteria was good response in 86% of the patients. DAS 28-4 (ESR) score and DAS28 improvement significantly decreased at 5 years from baseline (p<0.01 and p<0.001, respectively), and the moderate disease activity was achieved in 10 patients. High disease activity persisted in two patients. Drug retention rate at 5-year follow-up was 54% and the daily glucocorticoid therapy could be discontinued in 9 patients (47%). Three patients (15%) were tested positive for COVID-19. None of them required hospitalization and no deaths were occurred due to COVID-19. CONCLUSION: TOFA is effective and well-tolerated treatment options that reduce the need for steroids in patients with RA.
