ABSTRACT
Objectives: To describe the clinical characteristics and outcomes of SARSCoV-2 infection in patients with systemic vasculitis. Method(s): Observational, multicenter, cross-sectional analytical study in patients 18 or older diagnosed with systemic vasculitis with confirmed SARSCoV-2 infection (RT-PCR or serology) included in the SAR-COVID registry. Patients were evaluated from July 2020 to February 2022. Patients diagnosed with ANCA-associated vasculitis (AAV), other systemic vasculitides (Giant cell arteritis, Takayasu), and a control group of patients with other rheumatological diseases matched by age, sex, comorbidities, and date of SARS-CoV-2 infection. The survival curve of the groups was studied by Kaplan-Meier and compared through the Log-Rank Test. A Cox regression model will be performed to adjust survival for different variables (sex, age, treatments for underlying disease, treatments for viral infection, smoking, obesity, d-dimer level, and disease activity). Result(s): A total of 282 out of 2694 patients in the SAR-COVID registry were included, 57.4%women with a mean age of 55.7 years (SD 14.1). Fifty-four patients in the AAV group, 32 in the other vasculitis group, and 196 controls were studied. Hospitalization was required in 53.7% of the AAV group, 37.5% in other vasculitides, and 26.2% in the control group. 5.6% of patients in the control group presented acute respiratory distress syndrome (ARDS), 15.6% in the other vasculitis group, and 22.2% in the AAV group (p alpha 0.001). Complete recovery was observed in 82.3% of patients in the control group, 75%in the other vasculitis group, and 63%in the AAV group.We observed that 5.7% of the patients in the control group died from COVID-19, 9.4%from other vasculitides, and 27.8% in the AAV group (p alpha 0.001). We found a lower survival in the AAV group compared to the control group (p alpha 0.005). In the multivariate Cox regression model, older age (HR:1.05 IC95%1.01-1.09 p = 0.01), BMI > 40 (HR:13.2 IC95% 2.1-83.2 p = 0.01), and high activity of the underlying disease (HR:16 95% CI 3.7-69.4 p alpha 0.005) were associated with lower survival. Conclusion(s): In conclusion, patients diagnosed with AAV presented a worse disease course during SARS-CoV-2 infection with a more frequent requirement for invasive mechanical ventilation. Likewise, these patients showed lower survival compared to patients with other autoimmune diseases.
ABSTRACT
Coronavirus disease 2019 (COVID-19) is an inflammatory and infectious disease caused by severe acute respiratory syndrome coronavirus 2 virus with a complex pathophysiology. While COVID-19 vaccines and boosters are available, treatment of the disease is primarily supportive and symptomatic. Several research have suggested the potential of herbal medicines as an adjunctive treatment for the disease. A popular herbal medicine approved in the Philippines for the treatment of acute respiratory disease is Vitex negundo L. In fact, the Department of Science and Technology of the Philippines has funded a clinical trial to establish its potential as an adjunctive treatment for COVID-19. Here, we utilized network pharmacology and molecular docking in determining pivotal targets of Vitex negundo compounds against COVID-19. The results showed that significant targets of Vitex negundo compounds in COVID-19 are CSB, SERPINE1, and PLG which code for cathepsin B, plasminogen activator inhibitor-1, and plasminogen, respectively. Molecular docking revealed that alpha-terpinyl acetate and geranyl acetate have good binding affinity in cathepsin B;6,7,4-trimethoxyflavanone, 5,6,7,8,3',4',5'-heptamethoxyflavone, artemetin, demethylnobiletin, gardenin A, geranyl acetate in plasminogen;and 7,8,4-trimethoxyflavanone in plasminogen activator inhibitor-1. While the results are promising, these are bound to the limitations of computational methods and further experimentation are needed to completely establish the molecular mechanisms of Vitex negundo against COVID-19.
ABSTRACT
Background: Inclusion of historically underrepresented populations in research has been a problem existing for many years. The recent Covid pandemic has exposed the significant cost of gaps in access to care. There remains a need to reevaluate current research paradigm frameworks to consider tailored approaches that accommodate any location that would ease participant burden and maintain retention. Current decentralized research models include home and mobile options. However, barriers exist, and certain demographics remain elusive to recruitment into research studies. Aim(s): In this paper, we aim to identify a theoretical framework that will allow for more inclusivity in research. Methodology: Current utilized community-based decentralized research models are compared, barriers in recruitment and retention of interested participants are examined, and a framework individualized to study participants is offered. Result(s): The proposed framework expands upon the complex adaptive systems theory to incorporate community-based research which considers dividing studies into individual study visit components that may differ in location. It allows for ease of research participant access to care and mutual collaboration among providers and institutions. This new theoretical model expansion outlines a novel approach to communitybased participatory research for increased representation and inclusion. Conclusion(s): Investigators should carefully consider creative and effective solutions to overcome barriers to research participation access, increase diversity and representation, and provide tailored public health interventions. Minimally risk study intervention visits may occur in multiple community-driven locations such as: community resource centers, local physician offices, mobile research units, remote electronic visits, home settings, and a combination of the above (hybrid model). Breaking studies into individual study visit components expands the reach of science into the communities that have long been difficult to reach.
ABSTRACT
Background: COVID-19 vaccines are safe & effective, though patients with rheumatic diseases like idiopathic inflammatory myositis (IIMs), and those with multiple comorbidities continue to be hesitant. Adverse events after vaccination are not extensively studied in those with multiple coexisting autoimmune diseases. Patients with IIM often have multiple autoimmune rheumatic and autoimmune non-rheumatic comorbidities (IIM-AIDs), with potentially increased risk of AEs. The COVAD study aimed to assess COVID-19 vaccination-related AEs till 7 days post-vaccination in IIM-AIDs compared to IIMs and healthy controls (HCs) group. Method(s): T he C OVAD s tudy g roup c omprised > 110 c ollaborators across 94 countries. The study was conducted from March-December 2021. A survey monkey platform-based self-reported online survey captured data related to COVID-19 vaccination-related AEs in IIMs, AIDs, and HCs. We compared COVID-19 vaccination-related AEs among IIM-AID patients and IIM alone and HCs, adjusting for age, gender, ethnicity, vaccine type, immunosuppression, and numbers of AIDs, using binary logistic regression. Statistically significant results following multivariate regression are reported. Result(s): Among 6099 participants, 1387 (22.7%) IIM, 4712 (77.2%) HC, 66.3% females, were included from 18 882 respondents: 573 (41.0%) people with IIM-AIDs;814 (59.0%) with IIM without other AIDs;and 4712 HCs. People with IIM were older [median 54 (45-66) IIM-AIDs, 64 (50-73) IIM, 34 (26-47) HC years, P < 0.001]. BNT162b2 (Pfizer) (37.5%) and ChAdOx1nCoV-19 (Oxford) (11.1%) were the most common vaccines. When compared to IIM alone, IIM-AID patients reported higher overall AEs [OR 1.5 (1.1-2.1)], minor AE [OR 1.5 (1.1-2.1)] &major AE [OR 3 (1.5-5.8)]. IIM-AIDs patients also reported higher body ache, nausea, headache, & fatigue (OR ranging 1.3-2.3). After adjusting for the number of AIDs, the major AEs equalized but overall AEs, & minor AEs, such as fatigue remained higher. When compared to HCs, IIM-AIDs patients reported similar overall AEs, minor AEs but higher major AEs [OR 2 (1.2-3.3)] nausea/ vomiting [OR 1.4 (1.01-2)], headache [OR 1.2 (1.01-1.6)], and fatigue [OR 1.3 (1.03-1.6)]. Dermatomyositis with AIDs (n = 183) reported higher major AEs [OR 4.3 (1.5-12)] compared to DM alone (n = 293). Active IIM with AIDs (n = 482) reported higher overall AEs [OR 1.5 (1.1-2.2)], minor AEs [OR 1.5 (1.1-2.2)] and major AEs [OR 2.6 (1.2-5.2)] compared to active IIM alone (n = 643). Conclusion(s): COVID-19 vaccination is safe with minimal to no risks of short-term AEs in patients with IIM without other concomitant autoimmune diseases. The presence of autoimmune multimorbidity conferred higher self-reported short-term risks of overall, major, and minor COVID-19 vaccination-related AEs 7 days post-vaccination, particularly in those with active IIM.
ABSTRACT
This research presents a novel methodology and instructional, curricular design for the Cyber-Physical Systems and Human Factors Engineering course for an Industrial Engineering program in Higher Education. The research proposal offers a Competency-Based Education Model, Challenge-based Learning, and Experiential Learning design to create a curricular adaptation to prepare the future workforce for Industry 4.0, driven by digital technologies and strengthening the structure of Education 4.0 in pandemic times. The curricular design was explored and implemented in a national Industrial Engineering virtual course in five different facilities of a Higher Education Institution. Five professors participated in the exploratory study with 265 students in four country regions. The quantitative analysis provided positive findings regarding knowledge delivery and student competency development, confirming the good practices and standards in the proposed curricular design methodology. The final student evaluation results for the course have been favorable. They emphasized the importance of developing skills and knowledge about the enablers and components of Industry 4.0, such as Cyber-Physical-Systems and machine learning. Moreover, they remarked on the importance of human factors to develop a more sustainable society. The research contributes new ideas and perspectives for professors and instructional designers to shape the future of Higher Education. Furthermore, these new research paradigms for competencies in educational innovation shape the emerging virtual and hybrid educational practices in the COVID-19 pandemic and post-pandemic era.
ABSTRACT
The diaphragm is the most important respiratory muscle, and its function may be limited by acute and chronic diseases. A diaphragmatic ultrasound, which quantifies dysfunction through different approaches, is useful in evaluating work of breathing and diaphragm atrophy, predicting successful weaning, and diagnosing critically ill patients. This technique has been used to determine reduced diaphragmatic function in patients with chronic obstructive pulmonary disease and interstitial diseases, while in those with COVID-19, diaphragmatic ultrasound has been used to predict weaning failure from mechanical ventilation. © 2021 Lux et al.

ABSTRACT
Updated analysis confirms sustained poor prognosis of COVID-19 in patients with lymphoma in Latin America: A cohort of 160 patients from GELL. Introduction: Ongoing SARS-COV-2 pandemic has impacted the management of cancer patients worldwide. Several reports have demonstrated inferior outcomes of patients with hematological malignancies, including higher rates of intensive care unit admission, need for mechanical ventilation and death. The impact of COVID-19 is profound in resource-restricted countries, including Latin America. Most cohorts reported have not included patients from Latin America, and there is paucity of data of the outcome of cancer patients with COVID-19 in low- and middle-income countries. Grupo de Estudio De Linfoproliferativos En Latino-America (GELL )is a collaborative network of hematological centers in 13 countries in Latin America. We report updated outcomes of lymphoma patients diagnosed with COVID-19 in Latin America. Methods: We conducted a retrospective study including patients with a diagnosis of lymphoma and COVID-19 infection. Patients with chronic lymphocytic leukemia/small lymphocytic lymphoma were excluded from the analysis We defined active disease as follow: (1) patients with detectable disease either prior to initiating therapy or upon relapse, and/or (2) patients undergoing active cancer treatment. The primary outcome was overall survival at 100 days. Survival curves were estimated using the Kaplan Meier method. Uni and multivariable analysis were carried out with Cox model. Results: A total of 160 patients were available for analysis. Median age was 60 years old. Hypertension was the most common comorbidity (33%). Most patients had aggressive lymphomas (62%), including 43% of patients with diffuse large B-Cell lymphoma (DLBCL). Follicular lymphomas were observed in 13% of patients and Hodgkin lymphoma in 12.5% of patients. With a median follow-up of 37 days, the 100-day OS was 64% (95CI 56-74%, fig. 1). In univariate analysis, age (HR 1.03, p=0.0025), hypertension (HR 2.01, p=0.017), >1 number of prior lines (HR 2.78, p=0.011), patients currently on treatment (HR 1.83, p=0.043), ferritin >2000 ng/mL (HR 4.74 p=0.00047) were associated with inferior OS. In multivariate analysis, age (HR 1.03, p=0.0026) and patients currently on treatment (HR 1.82, p=0.04) had inferior OS. There was a trend towards inferior outcomes in patients receiving monoclonal antibodies in univariate analysis (HR 1.82, p=0.081) but not in multivariable analysis (HR=1.29, p=0.48). Use of steroids was not statistically related to mortality (HR 1.79, p=0.074). Finally, contrary to other cohorts, no improvement in OS was observed in patients diagnosed later on the pandemic (fig. 2). Conclusion: In this large cohort of Latin American patients with lymphoma malignancies, our updated analysis showed a maintained dismal prognosis with COVID-19 infection. With a median follow up of 37 days, the 100-day OS was 64%. Older age and ongoing active cancer treatment were significantly associated with mortality. The use of monoclonal antibodies and systemic corticosteroids were not statistically associated to poor survival. Current efforts are focused on improving immunization in the Latin American population. There is an unmet need for improving survival in patients with hematologic malignancies and COVID-19 infection.

ABSTRACT
INTRODUCTION: We designed and conducted a survey to analyze the impact of the COVID-19 pandemic on the operation and performance of the orthopedic departments of the National Health System and private entities. MATERIAL AND METHODS: Descriptive study of a survey is distributed to Spanish Ortohopedic surgeons via Internet. RESULTS: 401 valid responses were obtained, out of these 85.7% had to reduce their surgical activity between 50% and 100%. 46% of the sample were asked to collaborate in other units or services and another 43% felt that their work had been underused. 52% modified the treatment indications in various bone fractures, with variability between centers and communities. 30% reported being satisfied with the management from the state and 60% with that of their province and center. 70% showed little to no satisfaction with the training received on the use of masks and personal protective equipment. An additional of 80% were also unsatisfied with the training received with regard to sample-taking. 65% did not have protective equipment to carry out their work. 46% have been denied protective measures to treat patients with suspected or confirmed infection. CONCLUSION: The COVID-19 pandemic has placed the National Health System in an extremely serious situation. Through the analysis of the results, we can observe an inefficient use of available human resources, a widespread discontent, as well as an absence of means and measures, which has had a direct impact on the number of infected professionals.
