ABSTRACT

BACKGROUND: The COG-UK hospital-onset COVID-19 infection (HOCI) trial evaluated the impact of SARS-CoV-2 whole-genome sequencing (WGS) on acute infection, prevention, and control (IPC) investigation of nosocomial transmission within hospitals. AIM: To estimate the cost implications of using the information from the sequencing reporting tool (SRT), used to determine likelihood of nosocomial infection in IPC practice. METHODS: A micro-costing approach for SARS-CoV-2 WGS was conducted. Data on IPC management resource use and costs were collected from interviews with IPC teams from 14 participating sites and used to assign cost estimates for IPC activities as collected in the trial. Activities included IPC-specific actions following a suspicion of healthcare-associated infection (HAI) or outbreak, as well as changes to practice following the return of data via SRT. FINDINGS: The mean per-sample costs of SARS-CoV-2 sequencing were estimated at £77.10 for rapid and £66.94 for longer turnaround phases. Over the three-month interventional phases, the total management costs of IPC-defined HAIs and outbreak events across the sites were estimated at £225,070 and £416,447, respectively. The main cost drivers were bed-days lost due to ward closures because of outbreaks, followed by outbreak meetings and bed-days lost due to cohorting contacts. Actioning SRTs, the cost of HAIs increased by £5,178 due to unidentified cases and the cost of outbreaks decreased by £11,246 as SRTs excluded hospital outbreaks. CONCLUSION: Although SARS-CoV-2 WGS adds to the total IPC management cost, additional information provided could balance out the additional cost, depending on identified design improvements and effective deployment.

ABSTRACT

We extend our previous investigation of the effects of prehydrodynamic evolution on final-state observables in heavy-ion collisions [38] to smaller systems. We use a state-of-the-art hybrid model for the numerical simulations with optimal parameters obtained from a previous Bayesian study. By studying p-Pb collisions, we find that the effects due to the assumption of a conformal evolution in the prehydrodynamical stage are even more important in small systems. We also show that this effect depends on the time duration of the pre-equilibrium stage, which is further enhanced in small systems. Finally, we show that the recent proposal of a free-streaming with subluminal velocity for the pre-equilibrium stage, thus effectively breaking conformal invariance, can alleviate the contamination of final-state observables. Our study further reinforces the need for moving beyond conformal approaches in pre-equilibrium dynamics modeling, especially when extracting transport coefficients from hybrid models in the high-precision era of heavy-ion collisions.

ABSTRACT

Background: In many countries, non-pharmaceutical interventions to limit severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission resulted in significant reductions in other respiratory viruses. However, similar data from Africa are limited. We explored the extent to which viruses such as influenza and rhinovirus co-circulated with SARS-CoV-2 in The Gambia during the COVID-19 pandemic. Methods: Between April 2020 and March 2022, respiratory viruses were detected using RT-PCR in nasopharyngeal swabs from 1397 participants with influenza-like illness. An assay to detect SARS-CoV-2 and a viral multiplex RT-PCR assay was used as previously described to detect influenza A and B, respiratory syncytial virus (RSV) A and B, parainfluenza viruses 1-4, human metapneumovirus (HMPV), adenovirus, seasonal coronaviruses (229E, OC43, NL63) and human rhinovirus. Result(s): Overall virus positivity was 44.2%, with prevalence higher in children <5 years (80%) compared to children aged 5-17 years (53.1%), adults aged 18-50 (39.5%) and >50 years (39.9%), p<0.0001. After SARS-CoV-2 (18.3%), rhinoviruses (10.5%) and influenza viruses (5.5%) were the most prevalent. SARS-CoV-2 positivity was lower in children <5 (4.3%) and 5-17 years (12.7%) than in adults aged 18-50 (19.3%) and >50 years (24.3%), p<0.0001. In contrast, rhinoviruses were most prevalent in children <5 years (28.7%), followed by children aged 5-17 (15.8%), adults aged 18-50 (8.3%) and >50 years (6.3%), p<0.0001. Four SARS-CoV-2 waves occurred, with 36.1%-52.4% SARS-CoV-2 positivity during peak months. Influenza infections were observed in both 2020 and 2021 during the rainy season as expected (peak positivity 16.4%-23.5%). Peaks of rhinovirus were asynchronous to the months when SARS-CoV-2 and influenza peaked. Conclusion(s): Our data show that many respiratory viruses continued to circulate during the COVID-19 pandemic in The Gambia, including human rhinoviruses, despite the presence of NPIs during the early stages of the pandemic, and influenza peaks during expected months.Copyright: © 2023 Jarju S et al.

ABSTRACT

The coronations pandemic created a new world economic scenario. Social isolation measures in order to stop the spread of the virus, and the lack of prospects for improvement, have brought organizations an increase in risks and uncertainties about the business. Knowing the dependence on future events for the realization of contingent liabilities, this article, within the scope of the Prospectus Theory, aimed to assess whether, with the beginning of the pandemic in 2020, there was an increase in the amounts of contingent liabilities disclosed, and whether there was any change in the quality of their disclosure. In this way, data were collected from the financial statements of companies belonging to the sectors most affected by the pandemic, as published in the Official Gazette of the Union, and analyzed using quantitative methods. The results of the study showed that both before and after the beginning of the pandemic, the most representative liability contingencies among the companies studied were those of a Tax, Civil and Labor nature;and that no entity complied with all the disclosure requirements of CPC 25. Furthermore, the results obtained through the statistical analyzes did not identify a significant variation in the quality of disclosure or in the amount disclosed of contingencies after the beginning of the pandemic. These results contradict the recommendation of Circular Letter CVM/SNC/SEP 02/2020, which requires improvement in the disclosure of contingent liabilities as a result of the health crisis, which indicates possible failures regarding the disclosure of potential risks, and consequently interference in the decision-making process of users of accounting information.

ABSTRACT

The use of programs that facilitate and promote the dissemination of information has been transforming the relationship between government and society, increasing transparency and reducing bureaucracy in certain procedures, such as the Nota MT Program. This study sought to analyze the reflexes of fiscal citizenship promoted by the Nota MT Program from the perspective of Institutional Theory. The research is descriptive, with a quantitative approach and, regarding the documentary procedure. The population is made up of all registered users from the 141 municipalities in the State of Mato Grosso/Brazil. The period of analysis comprised the years 2018 to 2021, and was based on documents such as reports and bulletins from the Nota MT application of the Mato Grosso State Department of Finance -SEFAZ/MT, clarifications via email and legislation. state. The statistical treatment of the data obtained was performed using the SPSS 25 software (Statistic Packpage Social Science). Among the main results, it was identified that there was no statistically significant change in the adhesions to the Nota MT Program, a fact that may be related to the Covid-19 pandemic, which influenced the population's consumption pattern and made it difficult to disseminate and sweepstakes. However, comparing the beginning of 2019 with the end of 2021, it was possible to identify the change in population behavior by observing an increase (52%) in the number of invoices issued with CPF. Under the prism of Institutional Theory, this result indicates that the process of institutionalization of the program was legitimized by the population in the State of Mato Grosso.

ABSTRACT

Introduction: Vaccines prevent severe disease, but to prevent viral transmission and lessen the risk of new variants emerging they need to also enhance mucosal protection. Intramuscular (IM) vaccines induce systemic antibody and appear to transiently reduce transmission, but their effect on nasal antibody in previously infected subjects has not been studied. Aim(s): To study durability of local and systemic antibody responses after COVID-19 in those subsequently vaccinated. Method(s): Nasal fluid and plasma were collected from 448 hospitalised COVID-19 cases during admission and convalescence via the ISARIC4C/PHOSP-COVID studies. IgA/G to wildtype SARS-CoV-2 S, NP and to receptor binding domain (RBD) of Delta and Omicron variants were measured by ELISA. Result(s): Nasal IgA/G anti-S/RBD responses appeared within 28 days and remained high for 1 year(figure 1). Plasma IgA/G responses to S also remained elevated at 1 year(P<0.001). 87% of those with complete data were vaccinated between 6-12 months after infection;when nasal and plasma anti-NP IgA/G waned, whilst anti-S/RBD responses to Delta and Omicron were maintained or increased. Conclusion(s): This is the first study to demonstrate that IM vaccination may boost nasal antibody 1 year after COVID19. This may explain why IM vaccination reduces transmission, adding to the evidence for booster vaccines in COVID-19 recoverees. (Figure Presented).

ABSTRACT

This article addresses the use of public spaces by organized movements that led thousands of people to the streets between March 2015 and March 2016 and culminated in the President Dilma Rousseff impeachment. It starts from the premise that although the organization of these manifestations occurred through social networks, it was in the appropriation of public space by respective groups that they took place. In a timider way, due to the COVID 19 pandemic, the protesters returned to the streets in 2020. For the research, we used the theoretical contribution of urban space structuration and its symbolic dimension, followed by the compilation of information regarding protests published at major newspapers in circulation. The balance shows that the location of social manifestations followed the symbolic logic of urban space structuration, where the group opposed to the impeachment had its space of demonstration associated with the main center of cities and the groups that demanded the withdrawal of President Roussef occupied the spaces identified with the reproduction of financial capital and/or elite housing. This logic was maintained during the demonstrations that took place in 2020. © 2022 Universidad Nacional de Colombia. All rights reserved.

ABSTRACT

Introduction: The SARS-CoV 2 pandemic has brought a high burden of disease. Its long-term repercussions are still under investigation. The objective of this report was to evaluate the occupational, clinical, and functional respiratory recovery at 3 months of patients hospitalized for COVID-19, related to the ventilatory therapy received. Material(s) and Method(s): Prospective cohort of 116 patients from the Hospital Naval Almirante Nef de Vina del Mar, Chile, with clinical and functional respiratory follow-up at 3 months. Result(s): Median follow-up 100 days. 75 men, Median age 60 years, 50% obese, 34.5% smokers and 13.8% with respiratory comorbidity. 16% had undergo rehabilitation. Dyspnea in 73.7% and fatigue in 50%. Only 54.8% returned to work. 65% who used oxygen therapy (O2) returned to work compared to 44% who used HFNC and 33.3% IMV. Return to normal life achieved was greater in the O2 group compared with HFNC group and IMV group (71.4% versus 17.5% and 11.1%). Pulmonary function tests were normal in 39 patients (33.6%). Normal DLCO and normal distance walked in 6 minutes were higher in the group that return to work. The HNFC group had an OR of 5.9 of DLCO alterations, while VMI group had an OR of 3.6 in relation to the group that received O2. Discussion(s): This cohort repeats risk factors and persistence of symptoms described in literature. DLCO alteration was the most frequently founding and to a greater extent than other reports. Conclusion(s): At 3 months of follow-up, work absenteeism, persistence of symptoms and respiratory functional alteration were frequently evidenced, especially in those who received ventilatory support.

ABSTRACT

The COVID-19 pandemic created the need for universal vaccination. This study aimed to compare university students' (pre-service teachers) conceptions who had already learned the immune system and vaccination topics in the "Human Biology and Health (HBH)” curricular unit with those who had not yet taken part in it. It also intended to verify the influence of secondary school background, perception of one's own health, feeling at risk for COVID-19 and their own experience with it and scientific knowledge related to SARS-CoV-2 vaccination. It was a cross-sectional study with a mixed methodology for data analysis. A questionnaire was applied online to a sample of 102 university students. Results show that students who had already taken the subject on the immune system and vaccination had more acceptable conceptions about the vaccine and wanted to be vaccinated but not in the initial moment of the national vaccination process. The fear of adverse reactions seemed to be the major hesitancy factor. Furthermore, students' argumentation showed that their conceptions progressed towards more socio-scientific reasoning. © 2022 by the authors.

ABSTRACT

BACKGROUND: Barriers to rapid return of sequencing results can affect the utility of sequence data for infection prevention and control decisions. AIM: To undertake a mixed-methods analysis to identify challenges that sites faced in achieving a rapid turnaround time (TAT) in the COVID-19 Genomics UK Hospital-Onset COVID-19 Infection (COG-UK HOCI) study. METHODS: For the quantitative analysis, timepoints relating to different stages of the sequencing process were extracted from both the COG-UK HOCI study dataset and surveys of study sites. Qualitative data relating to the barriers and facilitators to achieving rapid TATs were included from thematic analysis. FINDINGS: The overall TAT, from sample collection to receipt of sequence report by infection control teams, varied between sites (median 5.1 days, range 3.0-29.0 days). Most variation was seen between reporting of a positive COVID-19 polymerase chain reaction (PCR) result to sequence report generation (median 4.0 days, range 2.3-27.0 days). On deeper analysis, most of this variability was accounted for by differences in the delay between the COVID-19 PCR result and arrival of the sample at the sequencing laboratory (median 20.8 h, range 16.0-88.7 h). Qualitative analyses suggest that closer proximity of sequencing laboratories to diagnostic laboratories, increased staff flexibility and regular transport times facilitated a shorter TAT. CONCLUSION: Integration of pathogen sequencing into diagnostic laboratories may help to improve sequencing TAT to allow sequence data to be of tangible value to infection control practice. Adding a quality control step upstream to increase capacity further down the workflow may also optimize TAT if lower quality samples are removed at an earlier stage.

ABSTRACT

This study aimed to understand the meaningful attitudes of alcoholic men and their expressions of feelings in the face of family and community interactions in times of the COVID-19 pandemic. This is a qualitative, descriptive, exploratory study, based on the Oral History of Life method. The participants of this study were five men who experience alcoholism, living in a municipality in the state of Bahia, accompanied by the Psychosocial Care Center for alcohol and other drugs. A semi-structured interview was used to collect information, from March to April 2021, through videoconferences through the Google Meet Digital Platform. The content of the oral reports was analyzed using a content analysis technique. It was observed that the significant attitudes of the alcoholic man were impacted by the unfolding of the pandemic, mainly due to the adoption of sanitary measures, such as social distancing. Some expressions of feelings were also identified of these men facing family and community interactions during the pandemic, such as fear, distrust, and affective insecurity, and social exclusion, in addition to expressions such as faith, gratitude, and hope. The participants' discourses expressed attitudes of changes in social life and habits during this pandemic period, including the use of masks and gel alcohol in addition to the decrease in alcohol consumption for most of them. Therefore, the symbolic interactions arising from the pandemic scenario promoted protective attitudes that encompass self-care and collective care, in addition to interactions marked by family conflicts. © 2022 Centro Universitario Sao Camilo.

ABSTRACT

Introduction: Orosomucoid also named Alpha-1 Acid Glycoprotein(AGP) is a major acute-phase protein and is increased in response to systemic injury and inflammation. AGP has been described as an inhibitor of neutrophil migration on sepsis, particularly its immunomodulation effects. The AGP biological functions are not understood in Coronavirus disease 2019 (COVID-19). Hypothesis: We hypothesize that plasmatic AGP is upregulated in severe Covid-19 patients and is involved in the regulation of netosis. Therefore, we sought to investigate the role of AGP in plasmatic from COVID-19 severe infection patients and neutrophils infected with Severe Acute Respiratory Syndrome Coronavirus-2 (SarsCov-2). Method(s): Epidemiological data and AGP, interleukin-6 (IL-6), C-reactive protein (PCR), lactate, and other laboratorial parameters were measured in blood samples from 52 subjects hospitalized in the ICU with clinically SarsCov-2 infection confirmed by RT-PCR. To evaluate the role of AGP in netosis in neutrophils, blood samples from health patients (n=13) were collected, and neutrophils were separated and infected with Sars-Cov-2 (Moi=1). Those neutrophils were treated with AGP (10mug/ml) or vehicle for 18 hours and netosis was analyzed by flow cytometry (n=10) and immunofluorescence (IF;n=10). Early and late netosis, respectively, were characterized by negative or positive FVS and positive Sytox. The neutrophil extracellular traps (NETs) were investigated by myeloperoxidase (MPO), neutrophil elastase (NE), and DAPI by IF and quantified Netquant/Matlab software. This study was approved by Ethics Committee -CAAE: 30816620.0.0000.5440. Result(s): AGP increased in severe Covid-19 patients (p<0.05). A positive correlation between AGP with IL-6 and C-reactive protein (respectively, p=0.005, p=0.002) and a negative correlation between AGP and lactate (p=0.004) were found it. Together, AGP treatment downregulated early (35,7%) and late (43,5%) netosis in neutrophils infected with SarsCov-2. Confocal analysis by MPO, NE e DAPI showed NETs released by neutrophils infected with Sar-Cov-2 decreased when neutrophils were treated with AGP (p<0.05). Conclusion(s): Our data showed increased AGP in COVID-19 infection and contributed to netosis regulation.

ABSTRACT

The structural changes involving the long arm of chromosome 3 at bands 3q21 and 3q26.2 in the form of inversion are named paracentric inversion inv(3)(q21q26.2) and in myeloid neoplasms have long been recognized, but are rare. The 3q21q26 syndrome usually occurs in a high-risk myelodysplastic syndrome (MDS) or the setting of acute myeloid leukemia (AML) and is most commonly reported as inv(3)(q21q26.2). Myeloid neoplasms with inv(3) are rare disorders with an incidence of 1% in MDS and AML. Thus, this report aims to show a patient with MDS and high platelets count who presented inv(3)(q21q26.2). A 72-year-old woman looked for medical attention due to fatigue and weakness. The patient reported a history of smoking for 41 years and denied any exposure to toxic agents. At physical examination, only pale was detected. A complete blood count revealed hemoglobin 7g/dL, MCV = 94 fL, leukocytes 5,600/mm3, neutrophils 2,242/mm3 and thrombocytosis with a platelet count of 514,000/mm3. Bone marrow aspirate showed dyserythropoiesis in 30% of cells and 6,5% blasts. The bone marrow cytogenetic analysis showed 46,XX,inv(3)(q21q26.2)[16]/46,XX[4]. The diagnosis of MDS with excess blasts - 1 was established according to the 2016 World Health Organization classification and International Prognostic Scoring System was very high. While waiting for beginning treatment, the patient died of respiratory failure due to COVID-19. Myelodysplastic syndrome with inv(3)(q21q26.2) is a rare aggressive disorder that occurs in less than 1% of all MDS cases and has been associated with a poor outcome: chemoresistance, high risk of leukemic transformation and short survival. Our case showed thrombocytosis with a platelet count of 514,000/mm3. The incidence of thrombocytosis in MDS has been reported in 8% of cases with platelets > 400 x109/L. The major report which evaluated thrombocytosis in MDS studied 2,042 cases, detecting high platelets count in 5% of cases (102/2,042). It appears that thrombocytosis does not adequately capture the aggressive nature of inv(3)(q21q26.2) in MDS but still plays an important role in the pathogenesis of this heterogeneous and dynamic disease. Our patient reported herein showed dyserythropoiesis in 30% of cells and 6,5% blasts, but nothing was detected regarding megakaryocytic lineage. Our patient died very soon after diagnosis due to viral infection. Thrombocytosis is an unusual clinical feature in MDS associated with inv(3)(q21q26.2) and the unfavorable prognosis of inv(3) is independent of thrombocytosis. Copyright © 2022

ABSTRACT

Television is among the preferred technological devices of the elderly due to their familiarity with its simple interface and because it acts as a sort of companion, being this especially relevant for those living alone. This phenomenon was particularly observed during the social isolation resulting from the Covid-19 pandemic. In the most critical period of the health crisis, the consumption of television content among older people and the adoption of other digital solutions aimed at entertainment or social interaction increased significantly. At the same time, technological advances in the television ecosystem have made it possible to include resources capable of making the gadget increasingly interactive and friendly. An example is the use of notifications, a mechanism that consists in displaying messages on the device's screen, engaging users to a specific topic. TV notifications can act as an information-focused tool with the potential to promote the connection of seniors with their family or friends. In the aforementioned context, the objective of this paper is to identify how TV notifications can contribute to reduce the rates of social isolation among the elderly, offering new forms of interaction with society. For, initially, a literature review was carried out to allow contextualizing the problem. Studies conducted in this field were evaluated to identify whether the television ecosystem would be able to enhance human relationship. These studies supported the construction of a questionnaire focused on identifying the habits of the elderly in relation to the adoption of technological devices, the consumption of television content and the acceptance of notifications in this context. Therefore, this study provides evidence that notifications can connect generations, being an important mechanism to reduce the rates of loneliness among older individuals. © 2022, Springer Nature Switzerland AG.
