RESUMEN
BackgroundSystemic lupus erythematosus (SLE) is an autoimmune disease, which presents an immune disorder that leads to the production of autoantibodies with potential involvement of multiple organs. Infections are one of the most frequent causes of hospitalization and death in lupus patients, and SARS-CoV-2 infection has been a global threat since March 2020. Immunization of these patients has been strongly recommended, although vaccine evaluation studies have not included this profile of patients.ObjectivesTo evaluate the immunogenicity and safety after 2 doses of the vaccine against SARS-CoV2 in patients with SLE.MethodsSubgroup of SLE patients from the prospective multicenter cohort of patients with immune-mediated diseases "SAFER” – Safety and Efficacy on COVID-19 Vaccine in Rheumatic Disease, a phase IV study. Vaccination against SARS-CoV-2 took place with vaccines approved by Brazilian regulatory bodies CoronaVac (Inactivated SARS-CoV-2 Vaccine), ChadOx-1 (AstraZeneca) and BNT162b2 (Pfizer-BioNTech) and this project followed in line with the guidelines of the National Immunization Plan in Brazil. Patients aged 18 years or older with a previous diagnosis of SLE (according to the 2019 ACR/EULAR criteria) were included. Patients were evaluated by telephone contact and in a face-to-face visit on the 28th day after each dose. Patients were followed up by means of blood collection for measurement of IgG antibody against SARS-COV-2 by chemiluminescence and disease activity assessed using SLEDAI-2K score.ResultsA total of 367 individuals with SLE were included, of whom 207 received 2 doses of CoronaVac, 128 received 2 doses of ChadOx-1 and 32 received 2 doses of BNT162b2. 90% of the subjects were female with a mean age of 37 years. About 42% (154) of the individuals included did not have any other associated comorbidity. 50% (182) of patients were using oral glucocorticoids and azathioprine was the most frequent immunosuppressive therapy. Regarding disease activity parameters, 38% (140) of patients had zero SLEDAI-2K at baseline and 41% (147) had zero SLEDAI-2K 28 days after the 2nd dose. Anti-DNA positivity was 30.7% (16/52) at inclusion and 32.6% (17/52) 28 days after the 2nd dose. Complement consumption was present in 18% (10/55) at inclusion and in 14.5% (8/55) 28 days after the 2nd vaccine dose. The geometric mean titers of IgG antibodies against SARS-COV-2 increased in the different vaccine groups, log 2.27 BAU/mL at inclusion and log 5.58 BAU/mL 28 days after the 2nd dose. Antibody titers after second dose varied between different vaccines, 4.96 BAU/mL CoronaVac, 6.00 BAU/mL ChadOx-1 and 7.31 BAU/mL BNT162b2 vaccine, p < 0.001. Only 3.54% (13/367) patients had covid-19 infection after the 15th day of the second dose of immunization, 9 of them having received 2 doses of CoronaVac, 4 of them of ChadOx-1 and none of them receiving BNT162b2, with p-value of 0.63.ConclusionThis study suggests that vaccines against SARS-COV-2 are safe in SLE patients. Induction of immunogenicity occurred in different vaccine regimens. Only 3.5% of individuals had COVID-19 infection with no difference between the types of vaccines evaluated. Future analyzes to explore the association of the effect of immunosuppressive medication, as well as the impact of booster doses and longer follow-up on clinical outcome will be performed.References[1]Mason A, et al.

RESUMEN
BackgroundPatients 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 comorbidities associated. However, few studies in the literature assessed the safety and immunogenicity of the COVID-19 heterologous vaccine schedules in patients with RA.ObjectivesEvaluate the safety and immunogenicity of two heterologous vaccine schedules against SARS-CoV-2 in patients with RA.MethodsThese data are from the study "SAFER - 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. Immunogenicity and adverse events (AEs) in patients with RA of all centers were assessed after two doses of ChAdOx1 plus additional dose of BNT162b2 or after two doses of inactivated SARS-CoV-2 vaccine CoronaVac plus additional dose of BNT162b2. The titers of neutralizing antibodies against the receptor-biding domain of protein spike (S) of SARS-CoV-2 (anti-RBD) were measured by chemiluminescence test after each dose of immunizers. Proportions between groups were compared using the chi-square and Fisher's exact tests for categorical variables. Clinical Disease Activity Index (CDAI) before and after vaccination was assessed using the McNemar test.ResultsA total of 107 patients with RA were include in the study, most of them female, with a mean age of 46 years. Biological disease modifying anti-rheumatic drugs (DMARDs) were used by 50 % of the patients and conventional synthetics DMARDs in 48 %. Two doses of CoronaVac plus additional dose of BNT162b2 was used in 66 patients and two doses of ChAdOx1 plus additional dose of BNT162b2 in 41. Only mild AEs were observed, mainly after the first dose. The most common AEs after all doses, regardless of the immunizer type, were pain at the injection, headache, arthralgia and myalgia. ChAdOx1 had a higher frequency of pain at the injection (66% vs 32 %, p < 0,001) and arthralgia (68% vs 15%, p < 0,001) compared to CoronaVac. No patients had flare after the vaccination. The titers of anti-RBD after two doses of ChAdOx1 were higher compared to two doses of CoronaVac (6,03 BAU/mL vs 4,67 BAU/mL, p < 0,001). However, after the additional dose of BNT162b2, the anti-RBD titers were similar in both groups (7.28 BAU/mL vs 7.06 BAU/mL, p = 0.56). Only two cases of COVID 19, with mild symptoms, were reported, one in each group.Figure 1.ConclusionChAdOx1, CoronaVac, and BNT162b2 vaccines are safe in RA patients. The frequency of local adverse effects, particularly pain at the injection site, is high. AEs are more frequent with ChAdOx1, especially after the first dose. The use of the immunizers does not change the degree of inflammatory activity of the disease. The immunogenicity of the two heterologous regimens analyzed was similar.References[1]Marques C, Kakehasi AM, Gomides APM, Paiva EDS, Dos Reis Neto ET, Pileggi GCS, et al.

RESUMEN
Objectives: To evaluate the safety and immunogenicity of CoronaVac and ChAdOx1 vaccines against SARS-CoV-2 in patients with Rheumatoid Arthritis (RA). Method(s): These data are from the 'SAFER (Safety and Efficacy on COVID-19 Vaccine in Rheumatic Diseases)' study, a Brazilian multicentric longitudinal phase IV study to evaluate COVID-19 vaccine in immunomediated rheumatic diseases (IMRDs). Adverse events (AEs) in patients with RA were assessed after two doses of ChAdOx1 or CoronaVac. Stratification of postvaccination AEs was performed using a diary, filled out daily. The titers of neutralizing antibodies against the receptor-biding domain of SARS-CoV-2 (anti-RBD) were measured by chemilumine scence test after each dose of immunizers. Proportions between groups were compared using the Chi-square and Fisher's exact tests for categorical variables. Clinical Disease Activity Index (CDAI) before and after vaccination was assessed using the McNemar test. Result(s): A total of 188 patients with RA were included in the study, most of them were female. CoronaVac was used in 109 patients and ChAdOx1 in 79. Only mild AEs were observed. The more common AEs after the first dose were pain at injection site (46,7%), headache (39,4%), arthralgia (39,4%) and myalgia (30,5%), and ChAdOx1 had a higher frequency of pain at the injection site (66% vs 32 %, p alpha 0.001) arthralgia (62% vs 22%, p alpha 0.001) and myalgia (45% vs 20%, p alpha 0.001) compared to CoronaVac. The more common AEs after the second dose were pain at the injection site (37%), arthralgia (31%), myalgia (23%) and headache (21%). Arthralgia (41,42 % vs 25 %, p = 0.02) and pain at injection site (51,43% vs 27%, p = 0.001) were more common with ChAdOx1. No patients had a flare after vaccination. The titers of anti-RBDafter two doses of ChAdOx1 were higher compared to two doses of CoronaVac (6,03 BAU/mL vs 4,67 BAU/mL, p alpha 0,001). Conclusion(s): The frequency of local adverse effects, particularly pain at injection site, was high. AEs were more frequent with ChAdOx1, especially after the first dose. The use of the immunizers dis not change the degree of inflammatory activity of the disease. In patients with RA, ChAdOx1 was more immunogenic than CoronaVac. .
RESUMEN
Objectives: Patients with immune-mediated rheumatic diseases (IMRDs) develop more severe outcomes of Coronavirus disease 2019 (COVID-19). Recent studies have contributed to understand the safety and efficacy of COVID-19 vaccines in IMRDs, suggesting that different diseases and therapies may interfere on immunization efficacy. In this study we analyze the immunogenicity of COVID-19 vaccines in patients with Systemic Vasculitides (VASC), the rate of COVID-19 and the frequency of disease relapse following immunization. Method(s): We included patients with VASC (n = 73), a subgroup of the SAFER study (Safety and Efficacy on COVID-19 Vaccine in Rheumatic Disease), a longitudinal, multicenter, Brazilian cohort.We analyzed the geometric means of IgG antibody against receptor-biding domain of protein spike of SARS-CoV-2 (anti-RBD) after two shots of CoronaVac (Inactivated vaccine), ChadOx-1 (AstraZeneca) or BNT162b2 (Pfizer-BioNTech). IgG anti-RBD was measured by chemiluminescence test. We assessed new-onset COVID-19 episodes, adverse events (AE) and disease activity for each VASC. Result(s): The sample included Behcet's disease (BD) (n = 41), Takayasu arteritis (TAK) (n = 15), antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) (n = 14), polyarteritis nodosa (n = 7) and other small vessel VASC(n = 6). The majority of patients were female (69%) without comorbidities (49%) and a median age of 37 years. The most common medication was conventional synthetic disease-modifying anti-rheumatic drugs, followed by biologic drugs. No patient received rituximab at baseline. Most patients received CoronaVac (n = 25) or ChadOx-1 (n = 36), while four received BNT162b2. Baseline IgG-RBD means were 1.34 BAU/mL. They increased to 3.89 and 5.29 BAU/mL after the 1st and 2nd vaccine dose, respectively. ChadOx-1 had higher antibody titers than CoronaVac (p = 0.002). There were no differences between different VASC. There were 3 cases of COVID-19 after immunization with CoronaVac. BD patients had a tendency for more cutaneous-articular activity following ChadOx-1. There were no severe relapses and no serious adverse events. Conclusion(s): Our results show the safety of different SARS-CoV-2 vaccines in VASC population. A progressive increase of IgG-RBD antibodies was observed after each dose. ChadOx-1 led to higher IgG-RBDgeometricmeans compared toCoronaVac. Finally, even though ChadOx-1 presented a tendency of triggering mild disease activity, there were no significant disease activity following vaccination in VASC patients. .
RESUMEN
Objectives: Systemic lupus erythematosus (SLE) is an autoimmune disease which presents infections as one of the most frequent complications, including more severe outcomes of Coronavirus disease 2019 (COVID-19). Immunization of these patients has been strongly recommended, however, data on safety are still scarce. In this study we evaluate the safety after vaccination against SARS-CoV2 in patients with SLE. Method(s): Safety and Efficacy on COVID-19 Vaccine in Rheumatic Disease - the 'SAFER' study, is a longitudinal Brazilian multicenter phase IV study. In this study patients with SLE (according to the 2019 ACR/EULAR criteria), older than 18 years who received vaccination against SARS-CoV-2 CoronaVac (Inactivated SARS-CoV-2 Vaccine), ChadOx-1 (AstraZeneca) and BNT162b2 (Pfizer-BioNTech) were included. The evaluation of adverse events (AEs) was done by telephone contact, symptom diaries and a face-to-face visit on the 28th day after each dose. Patients were followed up also by disease activity, assessed using SLEDAI-2 K score. Result(s): A total of 367 individuals with SLE were included, 207 received CoronaVac, 128 received ChadOx-1 and 32 received BNT162b2. Ninety percent of the subjects were female with a mean age of 37 years. About 50% (182) of patients were using oral glucocorticoids and azathioprine was the most frequent immunosuppressive therapy. Regarding disease activity parameters, 38%(140) of patients had zero SLEDAI-2Kat baseline and 41%(147) had zero SLEDAI-2 K 28 days after the 2nd dose. After the first and second dose the most frequent AEs were pain at injection site (58%/44%), headache (48%/33%) and pruritus (42%/37%). Comparing the three vaccines, after the first dose, local symptoms, myalgia, and fever were less frequent in patients who received CoronaVac (p alpha 0.001) as well as headache, tiredness (p = 0.001) and arthralgia (p = 0.003). After the second dose, only local symptoms such as pain at the application site and thickening of the skin around the application site were less frequent in the CoronaVac group (p alpha 0.05). Headache, tiredness, musculoskeletal symptoms and fever were more common in patients receiving AstraZeneca. No serious adverse events were reported regardless of the vaccination schedule used. Conclusion(s): This study suggests that vaccines against SARS-COV-2 are safe in SLE patients. Neither severe AEs were reported nor worsening of disease activity were reported. Comparing the different vaccines, CoronaVac had fewer adverse events.
RESUMEN
Objectives: The use of glucocorticoids (GC) has been associated with increased risk of hospitalization for coronavirus infection and reduced immunogenicity of SARS-CoV-2 vaccines in immune-mediated diseases (IMD) patients. However, there is still controversy of which dose of GC is correlated with impaired vaccine response on each of the diverse COVID-19 vaccines available, as well as the possible influence of other concurrent immunosuppressants. This study aimed at evaluating the effect of GC on serological response after two doses of BNT162b2 (Pfizer/BioNTech), CoronaVac (inactivated SARS-CoV-2 Vaccine) and ChadOx1 (AstraZeneca) and after the booster dose in patients with IMD. Method(s): The data were extracted from a multicenter longitudinal observational Brazilian cohort (SAFER: Safety and Efficacy on COVID19 Vaccine in Rheumatic Disease). Patients >18 years of age with IMD were evaluated after 2 doses of the same vaccine against COVID-19 and after a booster vaccine, applied according to Brazilian National Immunization Program. All patients underwent clinical examination and collected blood samples for immunogenicity tests. Serological response was evaluated by Anti-RBD titers (IgG) at baseline and 4 weeks after each vaccine dose. Result(s): Among the 1009 patients evaluated, 301 were using GC (196/401 SLE, 52/199 RA and 27/74 vasculitis). Patients using GC were younger (38.2 vs 40,8 years, p = 0,002), had higherBMI (27,6 vs 26,4 p = 0,008), higher prevalence of kidney disease (3,3% vs 0,5%, p = 0,001) and of thrombosis (11,6% vs 5,9%, p = 0,002) than non-users. Regarding the type of vaccine, most of the GC users received CoronaVac (61.7%), while only 31.9%of non-users received this vaccine (p alpha 0.001). Although there were similar rates of pre-vaccination infections among them, patients with GC tended to have a higher incidence of confirmed COVID-19 infection after the 2nd dose of the vaccine compared to non-users (4.5% vs 2.0% p = 0.054). The antibody titers after the 1st dose of COVID-19 vaccines were similar between groups, but there was a worse response in the GC group after the 2nd dose (p = 0.039). However, this difference was not statistically significant after the 3rd dose (Figure). Conclusion(s): GC use may compromise vaccine-induced immunogenicity after a 2-dose regimen;however, this effect does not remain significant after the booster dose. Multivariate analysis is still pending to assess the potential difference in the impact of GC on the immune response depending on GC dose, type of vaccine and associated drugs.
RESUMEN
Objectives: To evaluate the immunogenicity of ChAdOx1, Coronavac and BNT162B2 vaccines in SLE patients, including homologous and heterologous immunizations. Method(s): The 'Safety and efficacy on COVID-19 Vaccine in Rheumatic Disease-SAFER study' is a Brazilian multicentric longitudinal phase IV study to evaluate COVID-19 Vaccine in immune-mediated rheumatic diseases (IMRD) in real life, started on May 2021. SLE patients (according to the 2012 SLICC classification criteria), older than 18 years of age were recruited after 2 or 3 doses of vaccine against COVID-19 (ChAdOx1, BNT162b2 and CoronaVac) and were evaluated at baseline and on the 28th day after each dose. Homologous immunization was considered if they received three doses of the same vaccine and heterologous if a different one was applied. IgG antibody against SARS-CoV-2 spike receptor-binding domain were measured by chemiluminescence (SARS-CoV-2-IgG-II Quant assay, Abbott-Laboratories) at baseline and 28 days after the first, 2nd and 3rd doses (Seropositivity IgGSpike>= 7.1BAU/mL). Statistical analysis: ANOVA and pairwise comparisons tests Results: 316 SLE patients were included (255 heterologous and 61 homologous immunization), 89.2% were female and the mean age was 37.6 +/- 11.2 years. The two groups were homogeneous regarding demographical data, disease activity and immunosuppressive treatment. 49.7% used corticosteroids (alpha 5 mg/day in 52.3%), 83.5% antimalarials, 22.8% azathioprine and 20.3% mycophenolate mofetil. 207 patients received the first two doses with CoronaVac, 128 ChadOx-1 and 32 BNT162b2. Regarding the first two doses of the same vaccine, there was no difference in IgG titers over time between CoronaVac or ChadOx-1 (p = 0.313). IgG titers increased in all vaccine groups, with difference only after 2nd dose: 4.96 +/- 1.71BAU/mL CoronaVac vs. 6.00 +/- 1.99BAU/mL ChadOx-1 vs. 7.31 +/- 1.49BAU/mL BNT162b2 (p alpha 0.001). There was no difference in IgG titers over time between homologous or heterologous vaccine schedule (p = 0.872). IgG titers also increased in all groups, with difference only after 2nd dose: 5.49 +/- 1.96BAU/mL heterologous vs. 6.30 +/- 2.10BAU/mL homologous (p = 0.009). Conclusion(s): Induction of immunogenicity occurred in different vaccine regimens in SLE patients. Future research to explore different heterologous schemes in IMRD must be performed.
RESUMEN
Purpose: Our findings indicate that workers with more financial education were more prepared to face the negative effects on their finances from COVID. This ability reduces the probability of becoming financially fragile and experiencing financial stress. Design/methodology/approach: The authors applied a survey questionnaire to 856 Colombian adults and used principal component analysis to build an index for each factor. Then, the authors used a linear regression model with the indexes to test our hypotheses and verify our results using a structural equation model. Findings: Our findings indicate that workers who have more financial education are more prepared to face the negative effects on their finances, which reduces the probability of becoming financially fragile and having financial stress. Research limitations/implications: The authors found that there is no significant relationship between financial literacy and financial fragility, neither between financial literacy and financial stress, so a better financial education will not lower financial fragility and stress unless it is being applied by households through better financial preparedness. Practical implications: It is important to highlight that the pandemic not only taught us to improve biosecurity measures but also that financial strength, ability to work remotely and income diversification were key factors in facing this adverse shock, the authors show that high levels of financial education have a positively relationship with the ability of individuals to manage their resources, so private and public institutions have to promote better financial education. Originality/value: This is the first study that applies the four different indexes to an emerging country (i.e. Colombia), and the first one to create and use a financial stress index. © 2022, Raúl Armando Cardona-Montoya, Vivian Cruz and Samuel Arturo Mongrut.
RESUMEN
Background: Post Covid-19 syndrome is recognized as the maintenance of disease symptoms for weeks to months after the disease has healed. It is suspected that the involvement of the ACE enzyme and IL-6 may trigger an increased risk of dementia. Method(s): This is a cohort study that is evaluating over 12 months the functional status and cognition of elderly people after hospital discharge. One group is composed of elderly people admitted to the hospital for Covid-19 and the other group is composed of elderly people hospitalized for other clinical reasons. The groups are evaluated with The Mattis (DRS), AD8, IQCODE, ADCS-ADL, PCL-C, GDS-15, FIM, COPM, CFS, FSS, mMRC and SARC-calf. We will describe the preliminary results of the first 15 patients included in the COVID-19 group on functional status, cognition, mood and quality of life. Result(s): Fifteen patients with COVID-19 were evaluated three months after hospital discharge. One was excluded due to previous mental disorder and another due to a request to be excluded from the study. We found a mean age of 67.7 +/- 7.15 years, schooling 8.7 +/- 4.7 years, 61.5% female, Charlson Comorbidity Index 1.9 +/- 1.4, 69.2% with smoking history had incomplete vaccine protection for COVID-19. Considering cognition, 15.4% of the sample had no impairment, 53.9% had mild cognitive impairment (MCI) (30.8% amnestic MCI and 23.1% non-amnesic MCI) and 30.8% had dementia. 23.1% declared their health status and quality of life as fair or poor. Median CFS was 5 (3-5), mean GDS-15 was 4.7 +/- 2.9, FSS 32.9 +/- 18.9, PCL-c 32.6 +/- 12.5, SARC-calf 3.2 +/- 4.2. All had mMRC dyspnea classified between 2 and 4. Conclusion(s): There was a high prevalence of mild cognitive impairment and dementia among patients after three months of discharge, with a predominance of mild frailty due to CFS and the presence of fatigue. It is noteworthy that a quarter of the sample reported low quality of life. Copyright © 2022 the Alzheimer's Association.
RESUMEN
Background: Patients with autoimmune infammatory diseases (AID) have been prioritized for urgent vaccination to mitigate COVID-19 risk. However, few studies in the literature assessed the immunogenicity and safety of the COVID-19 vaccine in patients with AID. Objectives: In this context, the present study aims to evaluate the immunogenic-ity and safety of the vaccine against COVID-19 in patients with AID. Methods: These data are from 'Safety and efficacy on COVID-19 Vaccine in Rheumatic Disease'-SAFER study, a Brazilian multicentric prospective phase IV study to evaluate COVID-19 Vaccine in AID, in the real-life, in Brazil. Immunogenicity and adverse events (AE) from a single center were assessed, after 2 doses of ChAdOx1 (Oxford/AstraZeneca), 8 weeks of interval, in patients with AID and healthy controls (HC). Inclusion criteria were age ≥ 18 years and fulflling criteria according to international classifcation for AID. Exclusion criteria: pregnancy, previous severe AE to any vaccine, other immunosuppression causes. Stratifcation of post-vaccination AE was performed using a diary, flled out daily and returned at the end of 28 days for each dose. Participants were followed up through blood collection for measurement of IgG antibodies against SARS-CoV-2 spike receptor-binding domain by chemiluminescence (SARS-CoV-2 IgG II Quant assay, Abbott Laboratories, Abbott Park, IL, USA) at baseline and 28 days after the second dose. The seropositivity was defned for titers ≥50 AU/mL. Quantitative analyses were presented as observed frequency, percentage, central tendency, and variability measurements. The sample's normal distribution was verifed through the Shapiro-Wilk test. The Kruskal-Wallis test and the post-hoc Dwass-Steel-Critchlow-Fligner pairwise comparisons test were used to compare the IgG-S titers between the groups through the evaluation period. Categorical data were addressed using the Fisheŕs exact or Chi-squared (χ2) test. An alpha level of 5% signifcance was used in all analyses. Results: A total of 377 volunteers with AID and 50 HC were included in the study. Patients with spondyloarthritis (N=64), systemic lupus erythematosus (N=63), rheumatoid arthritis (N=61), primary Sjögren's syndrome (N=61), vasculitis (N=31), systemic sclerosis (N=14), inflammatory myopathy (N=9), Crohńs disease (N=49), ulcerative colitis (N=11) and other systemics AID (N=12) were evaluated. Both groups had female predominance (73.5% vs. 74.0%, p=0.937) and were homogeneous for age (43.5 vs. 41.7,p=0.308). The seroconversion among those not reactive (IgG-S negative at baseline) (46 HC and 191 AID), 28 days after second dose was 97.1% for spondyloar-thritis (p=0.425), systemic lupus erythematosus 88.2% (0.006), rheumatoid arthritis 93.5% (0.158), primary Sjögren's syndrome 92.6% (0.133), systemic sclerosis or inflammatory myopathy 47.1% (0.001), inflammatory bowel disease 100% (0.999) and vasculitis 80% (0.006), while in healthy control was 100%. In comparison with HC, there was a statistically significant difference in IgG-S titles only in systemic sclerosis or inflammatory myopathy (1.694 AU/ml vs. 3.719 AU/ml;p=0.006). Both groups only presented mild AE. Pain at the injection (85.7% vs. 78.4%, p=0.239), headache (67.3% vs. 53.8, p=0.074) and fatigue (59.2% Vs. 46.2%, p=0.089) were more common in HC than AID. Overall, reactions like arthralgia (52.6 vs. 22.4%, p<0.001), hematoma (14.1 vs. 4.1%, p=0.05), cutaneous rash (9.5 vs. 0%, p=0.024) were more frequent in AID. Most participants related that they felt safer after receiving a COVID-19 vaccination, and 52.4% did not reported a worse patient global assessment (PGA) index. Conclusion: In conclusion, our data indicated that ChAdOx1 vaccine is safe and induced high titers and seroconversion rate in AID. More severe AID, such as vasculitis, systemic lupus erythematosous, and systemic sclerosis and myositis showed a lower seroconversion rate. Further analysis will explore the association between immunossupressant and reactivity, and booster dose.
RESUMEN
Sustainable agriculture is urgently needed to promote conservation and sustainable resources use in an equitable manner through integrated management of land, water, energy and biodiversity. In this way, education in agriculture emerges as a crucial tool for preparing agricultural technicians, researchers and farmers for productive contributions. Higher education institutions arise with an important mission of education in the context of social transformation and to integrate sustainable development into the educational system as a scientific subject. The aim of this study was to identify the training and learning needs to be included in a MSc program in sustainable agriculture. It was based on a questionnaire prepared and distributed to academics' experts in Agrarian Sciences in Greece, Italy and Portugal. Technologies, legislation, management and business, local community leadership and marketing were the training needs considered very important expertise's in sustainable agriculture. Traditional face-to-face learning, experienced farmers as mentors and knowledge sharing mechanisms were rated as very applicable and important. Due to COVID-19 pandemic, online learning methods, which were not considered suitable for a MSc program in sustainable agriculture, became important by providing online education. Information and communication technology and technological tools showed to be important skills for sustainable agricultural practices to effectively implement online learning and to improve the efficient access, exposure and use of up-to-date information of the agricultural sector and awareness of sustainable agricultural practices.
RESUMEN
A novel SARS-CoV-2 coronavirus, the virus responsible for COVID-19, is a public health emergency of international concern since this infection spreads quickly through human-to-human transmission. Several drugs are being studied by researchers worldwide as an effective antiviral agent against this coronavirus. Therefore, most studies are focusing on drugs that have been already used earlier on the treatment of other diseases. Therapies under investigation include azithromycin, chloroquine, hydroxychloroquine, remdesivir, lopinavir/ritonavir, and favipiravir. Remdesivir is the only Food and Drug Administrationapproved drug for the use in adult and pediatric patients (>12 years old) for the treatment of this disease requiring hospitalization. In this context, the present review summarizes information about these drugs highlighting the chemical standpoint, such as physical-chemical and molecular characteristics, toxicity, history, and main applications, since knowledge about these substances is essential to assist the search for an appropriate treatment.
RESUMEN
Since the beginning of 2020, Peru has been exposed to the inevitable spread of Covid-19, a highly contagious disease that is increasing around the world rapidly. Scientists and researchers propose various solutions to mitigate its effects or reduce infections, from simple procedures to complex systems such as robots or vaccines. For this reason, innovative research was carried out from 2020 to 2021 under the supervision of the school of Mechatronics Engineering at U niversidad Tecnologica del Peru, so, this article, presents a SCARA robot prototype capable of performing rapid tests with blood samples to detect Covid-19.

RESUMEN
BACKGROUND: Androgen-deprivation therapy (ADT) has been associated with cognitive decline, but results are conflicting. This study describes changes in cognitive performance in patients with prostate cancer, according to ADT, during the first year after prostate cancer diagnosis. PATIENTS AND METHODS: Patients with prostate cancer treated at the Portuguese Institute of Oncology of Porto (n = 366) were evaluated with the Montreal Cognitive Assessment (MoCA), before treatment and after 1 year. All baseline evaluations were performed before the coronavirus disease 2019 (COVID-19) pandemic and 69.7% of the 1-year assessments were completed after the first lockdown. Cognitive decline was defined as the decrease in MoCA from baseline to the 1-year evaluation below 1.5 standard deviations of the distribution of changes in the whole cohort. Participants scoring below age- and education-specific normative reference values in the MoCA were considered to have cognitive impairment. Age- and education-adjusted odds ratios (aORs) were computed for the association between ADT and cognitive outcomes. RESULTS: Mean MoCA scores increased from baseline to the 1-year evaluation (22.3 versus 22.8, P < 0.001). Cognitive decline was more frequent in the ADT group, and even more after the onset of the COVID-19 pandemic (aOR 6.81 versus 1.93, P for interaction = 0.233). The 1-year cumulative incidence of cognitive impairment was 6.9% (9.1% before and 3.7% after the pandemic onset), which was higher among patients receiving ADT, but only after the pandemic (aOR 5.53 versus 0.49, P for interaction = 0.044). CONCLUSIONS: ADT was associated with worse cognitive performance of patients with prostate cancer, mostly among those evaluated after the first COVID-19 lockdown.

The SARS-CoV-2 coronavirus causes severe acute respiratory syndrome and has caused a global pandemic by causing the COVID-19 disease. To monitor and control it, diagnostic methods such as molecular and serological tests are necessary. The serological approach use SARS-CoV-2 antigens to detect the antibodies present in patients using quantitative techniques such as enzyme-linked immunosorbent assay (ELISA) or qualitative rapid tests such as lateral flow chromatography (RDT's). The main antigens used are the spike protein (S) and the nucleocapsid protein (N). Both proteins are obtained in different expression systems, in eukaryotic cells, their production is expensive, so in this work we chose a simpler and cheaper system such as prokaryotic to express and purify the N protein. Thereore, the nucleotide sequence had to being optimized to be expressed in Escherichia coli. The protein N is sensitive to E.coli proteases and also has the ability to self-proteolyze under native conditions, degrading into different fragments. However, under denaturing conditions, using urea and at pH 5.3 it is stable and efficiently purified using metal exchange chromatography (IMAC). In our purification strategy, we surprisingly found that by not using a sonicator, a homogeneous and time-stable preparation of the recombinant antigen is obtained. An approximate yield of 200 mg / L was obtained. It was then tested with healthy sera and sera from COVID-19 convalescent patients in Wester-blot tests that were able to recognize it. Our work provides a novel strategy to produce the SARS-CoV-2 protein N so that it can be used as an input in the development and innovation of serological tests in the diagnosis of COVID-19.

Introduction: The SARS-CoV-2 that causes Covid-19 not only affects the immune system, but also confinement has a great impact on the mental and physiological health of the population.
RESUMEN
Objective: The objectives of this study were to measure the global impact of the pandemic on the volumes for intravenous thrombolysis (IVT), IVT transfers, and stroke hospitalizations over 4 months at the height of the pandemic (March 1 to June 30, 2020) compared with two control 4-month periods. Background: The COVID-19 pandemic led to widespread repercussions on the delivery of health care worldwide. Design/Methods: We conducted a cross-sectional, observational, retrospective study across 6 continents, 70 countries, and 457 stroke centers. Diagnoses were identified by ICD-10 codes and/or classifications in stroke center databases. Results: There were 91,373 stroke admissions in the 4 months immediately before compared to 80,894 admissions during the pandemic months, representing an 11.5% (95%CI,-11.7 to-11.3, p<0.0001) decline. There were 13,334 IVT therapies in the 4 months preceding compared to 11,570 procedures during the pandemic, representing a 13.2% (95%CI,-13.8 to-12.7, p<0.0001) drop. Interfacility IVT transfers decreased from 1,337 to 1,178, or an 11.9% decrease (95%CI,-13.7 to-10.3, p=0.001). There were greater declines in primary compared to comprehensive stroke centers (CSC) for stroke hospitalizations (-17.3% vs-10.3%, p<0.0001) and IVT (-15.5% vs-12.6%, p=0.0001). Recovery of stroke hospitalization volume (9.5%, 95%CI 9.2-9.8, p<0.0001) was noted over the two later (May, June) versus the two earlier (March, April) months of the pandemic, with greater recovery in hospitals with lower COVID-19 hospitalization volume, high volume stroke center, and CSC. There was a 1.48% stroke rate across 119,967 COVID-19 hospitalizations. SARS-CoV-2 infection was noted in 3.3% (1,722/52,026) of all stroke admissions. Conclusions: The COVID-19 pandemic was associated with a global decline in the volume of stroke hospitalizations, IVT, and interfacility IVT transfers. Primary stroke centers and centers with higher COVID19 inpatient volumes experienced steeper declines. Recovery of stroke hospitalization was noted in the later pandemic months, with greater recovery in hospitals with lower COVID-19 hospitalizations, high volume stroke centers, and CSCs.
RESUMEN
The clinical features of COVID-19 differ substantially upon the presence (or absence) of viral pneumonia. The aim of this article was to describe the clinical characteristics of COVID-19 patients admitted to the Internal Medicine ward, as divided into those with and without pneumonia. This single-center prospective cohort study was conducted in a tertiary teaching public hospital in Buenos Aires City named Hospital General de Agudos Carlos G. Durand. Baseline data collection was performed within 48 hours of admission and patients were followed until discharge or in-hospital death. Epidemiological, clinical, laboratory, and radiological characteristics together with treatment data were obtained from the medical records. Of the 417 included, 243 (58.3%) had pneumonia. Median age was 43 years (IQR:32-57) and 222 (53.2%) were female. The overall crude case-fatality rate was 3.8%. None of the COVID-19 patients without pneumonia developed critical disease, required invasive mechanical ventilation nor died during hospitalization. However, 7 (4%) developed severe disease during follow-up. Among patients with COVID-19 pneumonia, in-hospital mortality rate was 6.6%, severe disease developed in 81 (33.3%), critical disease in 23 (9.5%), and 22 (9.1%) were admitted to the intensive care unit. A largely good prognosis was observed among COVID-19 patients without pneumonia, still, even among this group, unfavorable clinical progression can develop and should be properly monitored. Critical illness among patients with COVID-19 pneumonia was frequent and observed rates from this cohort provide a sound characterization of COVID-19 clinical features in a major city from South America.
RESUMEN
Background and aims: Internuclear ophthalmoplegia (INO) can be caused by a multitude of mechanisms leading to lesion of the medial longitudinal fasciculus (MLF), including infection. Currently, neurological manifestations have been described in COVID-19 patients, either due to immune mediated response or direct viral invasion of the central nervous system. Methods: Report of a clinical case Results: A previously healthy 54-year-old male presented with complaints of sudden onset dizziness and diplopia, preceded by self-limited diarrhea the day before. At examination the patient was apyretic. Neurological examination was striking for a hypertrophic right eye and a bilateral INO, but was otherwise unremarkable. Brain computed tomography scan with contrast was normal, as well as standard blood tests. RT-PCR for SARS-Cov2 was negative, as tests for HIV, VDRL, hepatitis A, B and C viruses, CMV, Borrelia, botulism and IGRA test. Stool microbiologic study was negative. Brain MRI and CSF studies were normal. Autoimmunity panel tests, including acetylcholine receptor antibody, anti-MuSK, anti-GQ1b and onconeural antibodies, were within normal range. A 5-day course of high-dose intravenous methylprednisolone was started, with progressive symptoms improvement and resolution of diplopia. One week after discharge, a serologic COVID-19 test was requested, which was positive for IgG and IgM, with a negative RT-PCR test. Conclusion: In this case, despite the lack of imaging findings, namely in the brainstem, the dramatic clinical response to anti-inflammatory therapy seems to favor an immune mediated mechanism. After extensive negative workup, the serologic positive test suggests a potential relationship between a bilateral INO and SARS-Cov2 infection.
