The aim of this quantitative study was to identify the socio-demographic and academic profile of intensive care registered nurses and participants of the events organized by the Department of Nursing of the Brazilian Association of Intensive Care Medicine. Data were collected by means of 400 questionnaires applied between January and July of 2010, however only 324 questionnaires were returned and 295 questionnaires were considered for the analysis. Data were analyzed with descriptive statistics resources with absolute relative frequency and simple mean, presented in tables. Results show the predominance of women, with specific graduate degrees. The skills and values highlighted include technical and scientific knowledge, and leadership. These professionals seek work in intensive care because of the high technological complexity. The study emphasized the existence of the professional profile required to work in the intensive care unit. The qualification of these professionals must prioritize the mastering of the technological language and the comprehensive and safe care.
Objetive:to identify risk factors for death in patients who have suffered
non-infectious adverse events. Method:a retrospective cohort study with patients who had non-infectious Adverse
Events (AE) in an Intensive Care Unit. The Kaplan Meier method was used to
estimate the conditional probability of death (log-rank test 95%) and the
risk factors associated with death through the Cox regression. Results:patients over 50 years old presented a risk 1.57 times higher for death;
individuals affected by infection/sepsis presented almost 3 times the risk.
Patients with a Simplified Acute Physiology Score III (SAPS3) greater than
60 points had four times higher risk for death, while those with a Charlson
scale greater than 1 point had approximately two times higher risk. The
variable number of adverse events was shown as a protection factor reducing
the risk of death by up to 78%.Conclusion:patients who had suffered an adverse event and who were more than 50 years of
age, with infection/sepsis, greater severity, i.e., SAPS 3>30 and
Charlson>1, presented higher risk of death. However, the greater number
of AEs did not contributed to the increased risk of death.
Objectives: The aim of the study was to evaluate mid-to late clinical and echocardiographic outcomes after transcatheter aortic valve replacement (TAVR) with Acurate neo™ (Boston Scientific, Boston, MA). Background: TAVR is an established treatment for aortic stenosis (AS). Few data exist on mid-to long-term outcomes and durability after new-generation valves. Methods: All consecutive patients (n = 104) who underwent Acurate neo™ implantation from 2012 to 2018 were included. Follow-up was systematically performed at 1, 6, 12, and 24 months and yearly thereafter. Outcomes were reported according to VARC-2, and structural valve deterioration (SVD) or bioprosthetic valve failure defined accordingly to new definitions. Results: Mean age was 82 ± 5.4 years, 56.7% were female and the Society of Thoracic Surgeons score for mortality was 5.9 ± 4%. Patients were followed for a median of 3 years (1,092 days; IQR 1.5-4 years), and the maximum follow-up was 7 years. All-cause mortality values at 1 and 5 years were 8.5% and 40.5%, respectively. No relevant changes in mean gradient and orifice area occurred (7.9 ± 3.8 mmHg and 1.9 ± 0.3 cm 2 at 1 year; 6.6 ± 2.1 mmHg and 1.8 ± 0.3 cm 2 at 5 years), and there was a significant rate of paravalvular leaks resolution at 1, 2, and 3 years (p = .004; p < .001; p < .001, respectively). None of the patients had leaflet thrombosis or endocarditis. One patient developed SVD at 84 months. Conclusions: Acurate neo™ was associated with sustained echocardiographic results. Reassuring mid-to long-term outcomes was observed in this cohort of elderly patients with severe AS.
Serological testing is a powerful tool in epidemiological studies for understanding viral circulation and assessing the effectiveness of virus control measures, as is the case of SARS-CoV-2, the pathogenic agent of COVID-19. Immunoassays can quantitatively reveal the concentration of antiviral antibodies. The assessment of antiviral antibody titers may provide information on virus exposure, and changes in IgG levels are also indicative of a reduction in viral circulation. In this work, we describe a serological study for the evaluation of antiviral IgG and IgM antibodies and their correlation with antiviral activity. The serological assay for IgG detection used two SARS-CoV-2 proteins as antigens, the nucleocapsid N protein and the 3CL protease. Cross-reactivity tests in animals have shown high selectivity for detection of antiviral antibodies, using both the N and 3CL antigens. Using samples of human serum from individuals previously diagnosed by PCR for COVID-19, we observed high sensitivity of the ELISA assay. Serological results with human samples also suggest that the combination of higher titers of antiviral IgG antibodies to different antigen targets may be associated with greater neutralization activity, which can be enhanced in the presence of antiviral IgM antibodies
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
