Multicenter Study
[Factors associated with the risk of COVID-19 in health-care workers].
Although healthcare personnel are considered a high-risk group for SARS-CoV-2 infection due to their exposure, research on the factors associated with their infection is limited. The objective was to identify factors associated with the acquisition of COVID-19 in healthcare personnel. ⋯ This study allowed us to identify different potentially modifiable factors on which action should be taken to reduce the risk of acquiring COVID-19 by the healthcare personnel.

During the SARS-CoV-2 pandemic, there was a marked requirement for critical care beds, supplies and trained professionals to assist patients with severe respiratory failure. The Argentine Society of Intensive Care (SATI) designed a study to characterize these aspects in intensive care units (ICUs). Multicenter, prospective cohort study; the participating ICUs completed a form at the end of the study (31/10/2020) on hospital characteristics, number of beds in pre- and intra-pandemic critical areas, incorporation of professionals, technological resources, and workload. ⋯ Oxygen therapy was required as noninvasive support in 14% [8-24] of COVID-19 admissions. There was a significant expansion of critical operational areas, secondary to the increase in beds, staff, and adequate availability of ventilators and essential supplies. The burden of critical illness from COVID-19 was intense, with more than half of patients on mechanical ventilation.

Given the vulnerability of chronic kidney disease individuals to SARS-CoV-2, nephrology societies have issued statements calling for prioritization of these patients for vaccination. It is not yet known whether COVID-19 vaccines grant the same high level of protection in patients with kidney disease compared to the non-dialysis population. The aims of this study were to evaluate the safety - measured by the adverse events potentially attributed to vaccines (ESAVI) - and the effectiveness - evaluated by the presence of antibodies - in dialysis patients immunized with the COVID-19 Sputnik V vaccine. ⋯ The Sputnik V vaccine has been shown to be safe and effective in this patient's population.

Multicenter study of diffuse pleural mesothelioma. Histopathological and immunohistochemical features.
The pathological diagnosis of diffuse pleural mesothelioma (DPM) contributes to treatment selection and clinical trials interpretation. To know its characteristics and evaluate the viability of comprehensive pathological diagnosis of DPM in Argentina we did a retrospective descriptive study of DPM cases reported from 2009 to 2018. We analyzed 398 cases corresponding to 238 (60%) men and 160 (40%) women, median age 66 years, from surgical biopsies (78%), small biopsies (16.5%) and surgical resections (5.5%). ⋯ The immunohistochemical antibody panel used included pan-cytokeratin, calretinin, WT-1, cytokeratin 5, CEA and TTF-1. The expression of cytokeratin 5, calretinin and WT-1 was lower in the sarcomatoid type (43%, 87 and 37%) than in the epithelioid type (92%, 98% and 93%). This study highlights the tumor heterogeneity of DPM that shows the diagnostic difficulty, and the feasibility of evaluating histological aggressiveness in E-DPM, B-DPM and S-DPM in our country.

The use of high-flow nasal therapy (HFNT) in patients with severe acute respiratory failure (SARF) due to COVID-19 pneumonia (NCOVID-19) is debated. Given the lack of beds in Intensive Care Units in the Public Health System of the Province of Neuquén, their use was implemented in general wards. This restrospective multicenter study was carried out to describe the experience of using HNFT in patients with SARF due to NCOVID-19. ⋯ The general IHM was 48.5% (145/299), 70.4% (93/132) in patients with IMV, 4.2% (5/120) died after successful weaning from HFNT and 100% (47/47) in the group not candidates for intubation. Patients with TNAFO had a statistically significant decrease in MIH and days of hospitalization. TNAFO in general wards achieved a decrease in the use of IMV, with a reduction in mortality and days of stay in hospitalized for NCOVID-19 with SARF.
