A single session of aerobic exercise reduces systolic blood pressure at rest and in response to stress in women with rheumatoid arthritis and hypertension.

Rheumatoid arthritis (RA) is an autoimmune inflammatory disease characterized by increased risk of cardiovascular disease and hypertension (HT). A single session of aerobic exercise may reduce blood pressure (BP) in different clinical groups; however, little is known about the acute effects of exercise on BP in RA patients. This is a randomized controlled crossover study that assessed the effects of a single session of aerobic exercise on resting BP, on BP responses to stressful stimuli, and on 24-h BP in women with RA and HT. Twenty women with RA and HT (53 ± 10 years) undertook sessions of 30-min treadmill exercise (50% VO2max) or control (no exercise) in a crossover fashion. Before and after the sessions, BP was measured at rest, and in response to the Stroop-Color Word Test (SCWT), the Cold Pressor Test (CPT), and an isometric handgrip test. After the sessions, participants were also fitted with an ambulatory BP monitor for the assessment of 24-h BP. A single session of exercise reduced resting systolic BP (SBP) (-5 ± 9 mmHg; p < 0.05), and reduced SBP response to the SCWT (-7 ± 14 mmHg; p < 0.05), and to the CPT (-5 ± 11 mmHg; p < 0.05). Exercise did not reduce resting diastolic BP (DBP), BP responses to the isometric handgrip test or 24-h BP. In conclusion, a single session of aerobic exercise reduced SBP at rest and in response to stressful stimuli in hypertensive women with RA. These results support the use of exercise as a strategy for controlling HT and, hence, reducing cardiovascular risk in women with RA.Clinical Trial Registration: This study registered at the Brazilian Clinical Trials ( https://ensaiosclinicos.gov.br/rg/RBR-867k9g ) at 12/13/2019.

Scleromalacia perforans as an early manifestation of late-onset rheumatoid arthritis: a case-based review.

Rheumatoid arthritis is a chronic autoimmune disease that can affect different organs beyond the joints. Ocular involvement includes keratoconjunctivitis sicca, peripheral ulcerative keratitis (PUK), episcleritis, scleritis, anterior uveitis, and corneal impairment. The most severe form of scleritis, scleromalacia perforans, is an aggressive ophthalmic manifestation that can potentially lead to blindness, usually occurring in late stages of disease. We report a case of an elderly woman in which this severe ocular manifestation occurred early on disease onset, differing from most of the previously reported cases of scleromalacia perforans. Ocular symptoms started concomitantly with the polyarthritis and other extra-articular manifestations, including rheumatoid nodules and vasculitic skin lesions. Ocular disease progressed due to patient's loss to follow-up, requiring pulse therapy with methylprednisolone. However, despite treatment, right eye enucleation was required due to melting of the corneal patch with uveal exposition. The patient was then treated with rituximab with improvement of systemic disease. The present case reinforces that, although rare, this complication is severe and must be promptly diagnosed and aggressively treated to improve prognosis of ocular and systemic RA.

Respiratory failure in systemic sclerosis.

Systemic sclerosis (SSc) can lead to dyspnea and respiratory failure through multiple mechanisms, making a precise diagnosis particularly challenging, especially amid the current COVID-19 pandemic. In this report, we present a case involving a 26-year-old female who had previously undiagnosed SSc. She experienced acute respiratory failure necessitating orotracheal intubation. Following an extensive evaluation, the patient exhibited skin thickening, kidney failure, thrombocytopenia, microangiopathic anemia, and an antinuclear antibody with a nuclear fine speckled pattern at a titer of 1:320. A diagnosis of SSc complicated by scleroderma renal crisis (SRC) was established. The patient's condition improved after undergoing hemodialysis, receiving an angiotensin-converting enzyme inhibitor, and undergoing cyclophosphamide treatment. Subsequently, she demonstrated sustained improvement during a follow-up period of 20 months.

Impact of switching between reference biologics and biosimilars of tumour necrosis factor inhibitors for rheumatoid arthritis: a systematic review and network meta-analysis.

What is the impact of switching between biologics and biosimilars of adalimumab, etanercept, and infliximab on efficacy and safety for rheumatoid arthritis? A systematic review and network meta-analysis were performed to compare switching and non-switching groups of treatments. Pooled Risk Relative (RR) or standardised mean differences (SMD) with 95% credible intervals (95% CrIs) were obtained. Seventeen randomized trials with a switching phase involving 6,562 patients were included. Results showed that a single switch from biologics to biosimilars compared to continuing biologics had comparable effects for primary and co-primary outcomes, the American College of Rheumatology criteria with 20% response (ACR20) (7 trials, 1,926 patients, RR 0.98, 95% CrIs 0.93 to 1.03) and the Health Assessment Questionnaire-Disability Index (HAQ-DI) (5 trials, 1,609 patients, SMD - 0.07, 95% CrIs - 0.23 to 0.1), and within the equivalence margins: ACR20 [RR 0.94, 1.06] and HAQ-DI [SMD - 0.22, 0.22]. The risk of treatment-emergent adverse events, discontinuation, and positive anti-drug antibodies were comparable after switching. Safety results were imprecise, and the follow-up period might not be sufficient to evaluate long-term effects, especially malignancies. Overall, the practice of single switching between approved biologics and biosimilars of Tumour Necrosis Factor inhibitors is efficacious and safe for rheumatoid arthritis.

Extra-articular manifestations of rheumatoid arthritis remain a major challenge: data from a large, multi-centric cohort.

INTRODUCTION: Although Rheumatoid Arthritis (RA) extra-articular manifestations (ExtRA) occurrence has been decreasing over time, they are still a major mortality risk factor for patients. OBJECTIVE: To determine the prevalence of ExtRA in a large cohort, and its association with demographic and clinical variables. METHOD: Cross-sectional and observational study, based on a multi-centric database from a prospective cohort, in which 11 public rheumatology centres enrolled RA patients (1987 ARA or 2010 ACR-EULAR). Data collection began in 08-2015, using a single online electronic medical record. Continuous variables were compared using Mann-Whitney U-test, and Fisher's exact test or chi-square test, as appropriate, were used for categorical variables. The level of significance was set at 5% (p < 0.05). RESULTS: 1115 patients were included: 89% women, age [mean ± SD] 58.2 ± 11.5 years, disease duration 14.5 ± 12.2 years, positive Rheumatoid Factor (RF, n = 1108) in 77%, positive anti-cyclic citrullinated peptide (ACPA, n = 477) in 78%. Regarding ExtRA, 334 occurrences were registered in 261 patients, resulting in an overall prevalence of 23.4% in the cohort. The comparison among ExtRA and Non-ExtRA groups shows significant higher age (p < 0.001), disease duration (p < 0.001), RF high titers (p = 0.018), Clinical Disease Activity index (CDAI) (p < 0.001), Disease Activity Index 28 (DAS 28) (p < 0.001), and Health Assessment Questionnaire (HAQ) (p < 0.001) in ExtRA group. Treatment with Azathioprine (p = 0.002), Etanercept (p = 0.049) Glucocorticoids (GC) ('p = 0.002), and non-steroidal anti-inflammatory drugs (NSAIDs) (p < 0.001) were more frequent in ExtRA group. CONCLUSIONS: ExtRA manifestations still show an expressive occurrence that should not be underestimated. Our findings reinforce that long-term seropositive disease, associated with significant disability and persistent inflammatory activity are the key factors related to ExtRA development.

Post-acute COVID-19 in three doses vaccinated autoimmune rheumatic diseases patients: frequency and pattern of this condition.

BACKGROUND: Data on post-acute COVID-19 in autoimmune rheumatic diseases (ARD) are scarce, focusing on a single disease, with variable definitions of this condition and time of vaccination. The aim of this study was to evaluate the frequency and pattern of post-acute COVID-19 in vaccinated patients with ARD using established diagnosis criteria. METHODS: Retrospective evaluation of a prospective cohort of 108 ARD patients and 32 non-ARD controls, diagnosed with SARS-CoV-2 infection (RT-PCR/antigen test) after the third dose of the CoronaVac vaccine. Post-acute COVID-19 (≥ 4 weeks and > 12 weeks of SARS-CoV-2 symptoms) were registered according to the established international criteria. RESULTS: ARD patients and non-ARD controls, balanced for age and sex, had high and comparable frequencies of ≥ 4 weeks post-acute COVID-19 (58.3% vs. 53.1%, p = 0.6854) and > 12 weeks post-acute COVID-19 (39.8% vs. 46.9%, p = 0.5419). Regarding ≥ 4 weeks post-acute COVID-19, frequencies of ≥ 3 symptoms were similar in ARD and non-ARD controls (54% vs. 41.2%, p = 0.7886), and this was also similar in > 12 weeks post-acute COVID-19 (68.3% vs. 88.2%, p = 0.1322). Further analysis of the risk factors for ≥ 4 weeks post-acute COVID-19 in ARD patients revealed that age, sex, clinical severity of COVID-19, reinfection, and autoimmune diseases were not associated with this condition (p > 0.05). The clinical manifestations of post-acute COVID-19 were similar in both groups (p > 0.05), with fatigue and memory loss being the most frequent manifestations. CONCLUSION: We provide novel data demonstrating that immune/inflammatory ARD disturbances after third dose vaccination do not seem to be a major determinant of post-acute COVID-19 since its pattern is very similar to that of the general population.

Therapeutic Equivalence of Biosimilar and Reference Biologic Drugs in Rheumatoid Arthritis: A Systematic Review and Meta-analysis.

Importance: Biosimilar drugs are potentially lower-cost versions of biologics that may improve access to therapy. However, there is a lack of adequate systematic reviews demonstrating equivalence between these drugs for the treatment of rheumatoid arthritis (RA). Objectives: To assess the efficacy, safety, and immunogenicity associated with biosimilars of adalimumab, etanercept, and infliximab compared with their reference biologics in patients with RA. Data Sources: MEDLINE via PubMed, Embase, Cochrane Central Register of Controlled Trials, and LILACS databases were searched from inception to September 2021. Study Selection: Head-to-head randomized clinical trials (RCTs) of biosimilars of adalimumab, etanercept, and infliximab and their biologic reference drugs for RA were assessed. Data Extraction and Synthesis: Two authors independently abstracted all data. Meta-analysis was conducted with bayesian random effects using relative risks (RRs) for binary outcomes and standardized mean differences (SMDs) for continuous outcomes, with 95% credible intervals (CrIs) and trial sequential analysis. Specific domains were assessed for the risk of bias in equivalence and noninferiority trials. This study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guideline. Main Outcomes and Measures: Equivalence was tested using prespecified margins for the American College of Rheumatology criteria, with at least 20% improvement in the core set measures (ACR20) (ie, RR, 0.94 to 1.06), and for the Health Assessment Questionnaire-Disability Index (HAQ-DI) (ie, SMD, -0.22 to 0.22). Secondary outcomes included 14 items measuring safety and immunogenicity. Results: A total of 25 head-to-head trials provided data on 10 642 randomized patients with moderate to severe RA. Biosimilars met equivalence with reference biologics in terms of ACR20 response (24 RCTs with 10 259 patients; RR, 1.01; 95% CrI, 0.98 to 1.04; τ2 = 0.000) and change of HAQ-DI scores (14 RCTs with 5579 patients; SMD, -0.04; 95% CrI, -0.11 to 0.02; τ2 = 0.002) considering prespecified margins of equivalence. Trial sequential analysis found evidence for equivalence for ACR20 since 2017 and HAQ-DI since 2016. Overall, biosimilars were associated with similar safety and immunogenicity profiles compared with reference biologics. Conclusion and Relevance: In this systematic review and meta-analysis, biosimilars of adalimumab, infliximab, and etanercept were associated with clinically equivalent treatment effects compared with their reference biologics for the treatment of RA.

Increased Prolonged Sitting in Patients with Rheumatoid Arthritis during the COVID-19 Pandemic: A Within-Subjects, Accelerometer-Based Study.

BACKGROUND: Social distancing measures designed to contain the COVID-19 pandemic can restrict physical activity, a particular concern for high-risk patient groups. We assessed rheumatoid arthritis patients' physical activity and sedentary behavior level, pain, fatigue, and health-related quality of life prior to and during the social distancing measures implemented in Sao Paulo, Brazil. METHODS: Post-menopausal females diagnosed with rheumatoid arthritis were assessed before (from March 2018 to March 2020) and during (from 24 May to 7 July 2020) social distancing measures to contain COVID-19 pandemic, using a within-subjects, repeated-measure design. Physical activity and sedentary behavior were assessed using accelerometry (ActivPAL micro). Pain, fatigue, and health-related quality of life were assessed by questionnaires. RESULTS: Mean age was 60.9 years and BMI was 29.5 Kg/m2. Disease activity ranged from remission to moderate activity. During social distancing, there were reductions in light-intensity activity (13.0% [-0.2 h/day, 95% CI: -0.4 to -0.04; p = 0.016]) and moderate-to-vigorous physical activity (38.8% [-4.5 min/day, 95% CI: -8.1 to -0.9; p = 0.015]), but not in standing time and sedentary time. However, time spent in prolonged bouts of sitting ≥30 min increased by 34% (1.0 h/day, 95% CI: 0.3 to 1.7; p = 0.006) and ≥60 min increased by 85% (1.0 h/day, 95% CI: 0.5 to 1.6). There were no changes in pain, fatigue, and health-related quality of life (all p > 0.050). CONCLUSIONS: Imposed social distancing measures to contain the COVID-19 outbreak were associated with decreased physical activity and increased prolonged sedentary behavior, but did not change clinical symptoms sitting among patients with rheumatoid arthritis.

As buscas foram realizadas nas seguintes bases de dados: US National Library of Medicine - National Institutes of Health; Scientific Electronic Library Online; Institute for Scientific Information; Cumulative Index to Nursing and Allied Health Literature; e SciVerse Scopus. Resultados foram selecionados 15 artigos que evidenciaram a influência dos fatores socioeconômicos na mortalidade infantil pelo Severe Acute Respiratory Syndrome Coronavirus 2. Conclusão evidenciou-se que os fatores socioeconômicos estão relacionados ao aumento da mortalidade por COVID-19 na população infantil, baixa renda e à residência em localidades consideradas de maior vulnerabilidade socioeconômica, as quais se apresentaram como importantes variáveis a serem consideradas na pandemia de COVID-19. Contribuições para a prática diversos fatores estão relacionados ao aumento da suscetibilidade à infecção do Severe Acute Respiratory Syndrome Coronavirus e agravamento da doença em crianças. No entanto, compreender que os fatores socioeconômicos podem se apresentar como um determinante na incidência e mortalidade por COVID-19 na população infantil ressalta a necessidade de investimentos em ações direcionadas à redução das desigualdades socioeconômicas, para assim reduzir as mortes evitáveis.

ABSTRACT Objective to identify the scientific evidence on the relationship between socioeconomic factors and mortality in children due to COVID-19. Methods this is a scoping review. Searches were carried out in the following databases: US National Library of Medicine - National Institutes of Health; Scientific Electronic Library Online; Institute for Scientific Information; Cumulative Index to Nursing and Allied Health Literature; and SciVerse Scopus. Results 15 articles were selected that showed the influence of socioeconomic factors on infant mortality from Severe Acute Respiratory Syndrome Coronavirus 2. Conclusion it was shown that socioeconomic factors are related to increased mortality from COVID-19 in the infant population, low income and residence in locations considered to be of greater socioeconomic vulnerability, which were presented as important variables to be considered in the COVID-19 pandemic. Contributions to practice several factors are related to increased susceptibility to Severe Acute Respiratory Syndrome Coronavirus infection and worsening of the disease in children. However, understanding that socioeconomic factors can be a determinant of COVID-19 incidence and mortality in children highlights the need to invest in actions aimed at reducing socioeconomic inequalities, to reduce preventable deaths.

Conclusions ExtRA manifestations still show an expressive occurrence that should not be underestimated. Our findings reinforce that long-term seropositive disease, associated with significant disability and persistent inflammatory activity are the key factors related to ExtRA development.

Novel time-domain NMR-based traits for rapid, label-free Olive oils profiling.

Olive oil is one of the oldest and essential edible oils in the market. The classification of olive oils (e.g. extra virgin, virgin, refined) is often influenced by factors ranging from its complex inherent physiochemical properties (e.g. fatty acid profiles) to the undisclosed manufacturing processes. Therefore, olive oils have been the target of adulteration due to its profitable margin. In this work, we demonstrate that multi-parametric time-domain NMR relaxometry can be used to rapidly (in minutes) identify and classify olive oils in label-free and non-destructive manner. The subtle differences in molecular microenvironment of the olive oils induce substantial changes in the relaxation mechanism in the time-domain NMR regime. We demonstrated that the proposed NMR-relaxation based detection (AUC = 0.95) is far more sensitive and specific than the current gold-standards in the field i.e. near-infrared spectroscopy (AUC = 0.84) and Ultraviolet-visible spectroscopy (AUC = 0.73), respectively. We further show that, albeit the inherent complexity of olive plant natural phenotypic variations, the proposed NMR-relaxation based traits may be a viable mean (AUC = 0.71) in tracing the regions of origin for olive trees, in agreement with their geographical orientation.

Métodos: estudio observacional, retrospectivo y analítico. Los datos se recopilaron del 4 de febrero de 2020 al 25 de julio de 2021. El modelo que compara personas con y sin cardiopatía se ajustó por sexo, grupo de edad, obesidad y diabetes, posibles variables de confusión. Las comparaciones se analizaron mediante el modelo de regresión log-binomial y el cálculo del riesgo relativo. Resultados: las personas del estado de São Paulo, con cardiopatías, infectadas por COVID-19 entre 21 y 50 años tenían mayor riesgo de muerte en comparación con las personas sin cardiopatías. Además, las mujeres con cardiopatías mayores de 51 años tenían un menor riesgo de muerte en comparación con los hombres con cardiopatías del mismo grupo de edad. Conclusión: las personas con cardiopatías infectadas por COVID-19, especialmente los hombres, tienen mayor riesgo de muerte, en el estado de São Paulo.

New Alternatives to Milk From Pulses: Chickpea and Lupin Beverages With Improved Digestibility and Potential Bioactivities for Human Health.

There is a strong demand for plant-based milk substitutes, often low in protein content (<1.5% w/v). Protein-rich pulse seeds and the right processing technologies make it possible to make relevant choices. The major objective of this study was to assess the impact of processing on the nutritional characteristics of beverages with a high impact on health, in particular on digestibility and specific bioactivities. The results suggest that pulse beverages are as high in protein content (3.24% w/v for chickpea and 4.05% w/v for lupin) as cow's milk. The anti-nutrient level characteristics of pulses have been considerably reduced by strategic processing. However, when present in small quantities, some of these anti-nutritional factors may have health benefits. Controlling processing conditions play a crucial role in this fine balance as a tool to take advantage of their health benefits. There is evidence of protein hydrolysis by in vitro digestion and limited bioaccessibility of minerals. In addition to being highly digestible, lupin and chickpea beverages have anti-inflammatory and anti-carcinogenic potential evaluated through the inhibition of metalloproteinase MMP-9.

Physical activity and antibody persistence 6 months after the second dose of CoronaVac in immunocompromised patients.

This prospective cohort study within an open-label, single-arm, phase 4 vaccination trial (clinicaltrials.gov #NCT04754698) aimed to investigate the association between physical activity and persistent anti-SARS-CoV-2 antibodies 6 months after two-dose schedule of CoronaVac in autoimmune rheumatic diseases (ARD) patients (n = 748). Persistent immunogenicity 6 months after the full-course vaccination was assessed using seroconversion rates of total anti-SARS-CoV-2 S1/S2 IgG, geometric mean titers of anti-S1/S2 IgG (GMT), and frequency of positive neutralizing antibodies (NAb). Physical activity was assessed trough questionnaire. Adjusted point estimates from logistic regression models indicated that physically active patients had greater odds of seroconversion rates (OR: 1.5 [95%CI: 1.1 to 2.1]) and NAb positivity (OR: 1.5 [95%CI: 1.0 to 2.1]), and approximately 43% greater GMT (42.8% [95%CI: 11.9 to 82.2]) than inactive ones. In conclusion, among immunocompromised patients, being physically active was associated with an increment in antibody persistence through 6 months after a full-course of an inactivated SARS-CoV-2 vaccine.
