Abstract Background Patients with immune-mediated rheumatic diseases (IMRDs) have been prioritized for COVID-19 vaccination to mitigate the infection severity risks. Patients with rheumatoid arthritis (RA) are at a high risk of severe COVID-19 outcomes, especially those under immunosuppression or with associated comorbidities. However, few studies have assessed the safety of the COVID-19 vaccine in patients with RA. Objective To evaluate the safety of vaccines against SARS-CoV-2 in patients with RA. Methods This data are from the study “Safety and Efficacy on COVID-19 Vaccine in Rheumatic Diseases,” a Brazilian multicentric prospective phase IV study to evaluate COVID-19 vaccine in IMRDs in Brazil. Adverse events (AEs) in patients with RA of all centers were assessed after two doses of ChAdOx1 (Oxford/AstraZeneca) or CoronaVac (Sinovac/Butantan). Stratification of postvaccination AEs was performed using a diary, filled out daily and returned at the end of 28 days for each dose. Results A total of 188 patients with RA were include, 90% female. CoronaVac was used in 109 patients and ChAdOx1 in 79. Only mild AEs were observed, mainly after the first dose. The most common AEs after the first dose were pain at the injection (46,7%), headache (39,4%), arthralgia (39,4%), myalgia (30,5%) and fatigue (26,6%), and ChAdOx1 had a higher frequency of pain at the injection (66% vs 32 %, p < 0.001) arthralgia (62% vs 22%, p < 0.001) and myalgia (45% vs 20%, p < 0.001) compared to CoronaVac. The more common AEs after the second dose were pain at the injection (37%), arthralgia (31%), myalgia (23%), headache (21%) and fatigue (18%). Arthralgia (41,4% vs 25%, p = 0.02) and pain at injection (51,4% vs 27%, p = 0.001) were more common with ChAdOx1. No serious AEs were related. With Regard to RA activity level, no significant difference was observed between the three time periods for both COVID-19 vaccines. Conclusion In the comparison between the two immunizers in patients with RA, local reactions and musculoskeletal symptoms were more frequent with ChAdOx1 than with CoronaVac, especially after the first dose. In summary, the AE occurred mainly after the first dose, and were mild, like previous data from others immunizing agents in patients with rheumatoid arthritis. Vaccination did not worsen the degree of disease activity. immunemediated immune mediated (IMRDs COVID19 COVID 19 COVID-1 risks (RA outcomes comorbidities However SARSCoV2 SARSCoV SARS CoV 2 SARS-CoV- Safety Diseases, Diseases Brazil (AEs ChAdOx Oxford/AstraZeneca OxfordAstraZeneca Oxford AstraZeneca (Oxford/AstraZeneca Sinovac/Butantan.

Abstract The geotechnical monitoring of tailings dams combined with a suitable application of geophysical electrical methods can improve their structure evaluation, allowing several correlations between direct analyses and the resistivity anomaly pattern. Considering this synergy, twenty-three electrical resistivity sections (ERT) were acquired along the beach, abutments, and central part of a dam, totalizing 10,776 m of dataset. After the interpretation of each ERT section, comparing the anomaly ranges with the water level meters measurements, three resistivity zones were defined: Zones of low resistivity (<64 ohm-m), correlated to regions of high humidity; zones of high resistivity (> 357 ohm-m), interpreted as dry zones, and regions with intermediate resistivity values, located between these limits. The groundwater surface generated from the interpretation of the electrical resistivity dataset and the groundwater surface acquired from the water level gauges were almost coincident. On the right abutment, the conductive anomalies showed remarkable continuity, suggesting a high moisture content in this region with strong gradients (200 mV) directed towards the zone of low resistivity values identified in the sections. The analysis showed a robust correlation of the ERT data with localized physical geotechnical measurements, valuable for monitoring dam integrity, overseeing the structure's response to climate and operational changes, and ultimately mitigating the risks of failure. The results of this study support the adoption of a seasonal 4D electrical resistivity survey as an effective tool to monitor and manage surface and high humidity zones, key indicators of dam integrity throughout the entire structure. evaluation pattern synergy twentythree twenty (ERT beach abutments 10776 10 776 10,77 section measurements defined <64 64 (<6 ohmm, ohmm ohm , ohm-m) > ( 35 limits coincident abutment continuity 200 (20 mV structures s changes failure D 1077 1 77 10,7 <6 6 (< ohm-m 3 20 (2 107 7 10, < 2
