COVID-19 exposure setting, social and gender determinants in a Mediterranean region

BACKGROUND: Knowledge of social and gender determinants, which influence the places where people are exposed to COVID-19, may be relevant in the development of preventive and control strategies. The aim of this paper was to determine the context in which COVID-19 cases were infected (household, work/labor, health, social-health, and social-leisure settings) according to country of origin, occupational social class and gender, which is essential in order to designing public health strategies. METHODS: A cross-sectional study of an epidemiological registry of 56,628 COVID-19 incident cases was made, whose exposure/ contagion setting was studied according to the previous variables from June 15 to December 23, 2020, in the Region of Murcia (Spain). An exact Fisher test was used to study the distribution of COVID-19 cases based on the above variables. RESULTS: The cumulative incidence was higher in people from Africa (5,133.5 cases/100,000 inhabitants) and Latin America (11,351.1) than in non-immigrants (3,145.7). It was also higher in women (3,885.6) than in men (3,572.6). It is noteworthy, that 53.3% of the cases with employment were workers in industry or construction, artisans, agricultural workers, or elementary occupations. In contrast, during the second semester of 2020, 41.3% of the employed population in the Region of Murcia performed such jobs. The household was the main exposure setting (56.5% of cases with a known setting), followed by social-leisure (20.7%) and work/labor (18.2%). The labor settings were more important in immigrants from Africa (28.4%) and Latin America (35.7%) than in non-immigrants (12%), inversely to social-leisure settings. Labor context was more important in women (19.6%) than in men (16.5%) and in manual workers (44.1%) than in non-manual workers (26.6%). CONCLUSIONS: The context in which COVID-19 cases were infected is different according to social inequalities related to country of origin, gender and occupational social class.

Targeting Spike Glycans to Inhibit SARS-CoV-2 Viral Entry

SARS-CoV-2 Spike harbors glycans which function as ligands for lectins. Therefore, it should be possible to exploit lectins to target SARS-CoV-2 and inhibit cellular entry by binding glycans on the Spike protein. Burkholderia oklahomensis agglutinin (BOA) is an antiviral lectin that interacts with viral glycoproteins via N-linked high mannose glycans. Here, we show that BOA binds to the Spike protein and is a potent inhibitor of SARS-CoV-2 viral entry at nanomolar concentrations. Using a variety of biophysical tools such as SEC chromatography, dynamics light scattering, fluorescence binding assays, and electron microscopy, we demonstrate that the interaction is avidity driven and that BOA crosslinks the Spike protein into soluble aggregates. Furthermore, using virus neutralization assays, we demonstrate that BOA effectively inhibits all tested variants of concern as well as SARS-CoV-1, establishing that glycan-targeting molecules have the potential to be pan-coronavirus inhibitors.Copyright © 2023 The American Society for Biochemistry and Molecular Biology, Inc.

Propofol and COVID-19 infusion syndrome. Case report

The severe form of SARS-CoV-2 pneumonia (COVID-19) occurs in most cases with acute respiratory distress syndrome (ARDS), requiring the use of sedation during mechanical ventilation, with propofol being the most widely used for its pharmacokinetics and pharmacodynamics. Propofol is a widely used anesthetic in intensive care units (ICU). Its use can cause an infrequent but extremely serious adverse effect, known as propofol infusion syndrome (PRIS), which is closely associated with the speed of infusion coupled with risk factors specific to the patient, the clinical features of PRIS are hemodynamic instability, lactic acidosis and with progression to multi-organ dysfunction. We present a case of SIP in a patient with acute respiratory distress syndrome (ARDS) secondary to SARS-CoV-2 who develops this complication associated with sedation, discusses clinical pathophysiology and considerations that should be taken into account when using it in continuous infusion. © 2023, Colegio Mexicano de Anestesiologia A.C..

Teachers in pandemic: professional identity from the written media

This study sought to describe and interpret the subjective theories about the teacher's professional identity that are constructed and disseminated in the news during emergency education due to the COVID 19 pandemic. A documentary analysis study, qualitative methodology and a case study design were used. The purposive and convenience sampling corresponds to 40 news items from the press written in Spanish, about the teacher in a pandemic and published in different media that were collected through Google News from March 11 2020 and March 1 2020 until November 01 2020. Based on a thematic coding, the results evidenced subjective theories associated with the demanding characteristics, roles, functions, and values with which teachers identify during the pandemic. The analysis showed the different meanings of professional practice and the skills associated with their performance in the press. In the discussion, studies relating to teaching practice were used to interpret these results. © 2022 Logos: Revista de Linguistica, Filosofia y Literatura. All rights reserved.

SARS-CoV-2 seroprevalence among patients with cancer and healthcare workers from an oncology referral center during the first year of COVID-19 vaccination in Mexico

Background. Cancer patients (CPs) with COVID-19 have an increased risk of adverse outcomes. In addition, CPs seem to have a lower immune response to SARS-CoV-2 vaccination. This study aimed to evaluate SARS-CoV-2 spike antibodies (anti-S Abs) following COVID-19 vaccination in CPs and healthcare workers (HCWs). Methods. We conducted a point-seroprevalence study in CPs and HCWs who received a two-dose scheme with either BNT162b2, AZD1222, or Sputnik-V vaccine. We measured anti-S Abs by quantitative immunoassay to assess humoral immune response. Besides, we quantified anti-nucleocapsid antibodies in a subgroup of individuals to determine prior infection. We compared anti-S Abs titers in both groups and stratified by vaccine type, prior infection, and clinical characteristics. We conducted a multivariate logistic regression to determine variables associated with a poor humoral response. Results. Six hundred forty-one individuals were included: 174 (27%) CPs and 467 (73%) HCWs. The median anti-S Abs titter was higher among HCWs compared to CPs (2568 U/mL vs. 1807 U/mL, p=0.002). Both CPs and HCWs with prior infection had higher anti-S Abs titter (p< 0.001). Regardless of the time since vaccination, a higher proportion of subjects with titers < 250 U/mL was observed in CPs (p< 0.001) (Fig 2). In the multivariate analysis, older age (p=0.036), AZD1222 (p=0.003), and Sputnik-V (p=0.020) were associated with lower humoral response among the entire cohort. SARS-CoV-2 spike antibody titers among cancer patients and healthcare workers. Global differences in anti-S Abs titers between CPs and HCWs groups (a) and antibody titers in CPs and HCWs groups stratified by type of received vaccine (b). Abbreviations: CP: Cancer patients, HCW: Healthcare workers. SARS-CoV-2 spike antibody titers according to time since vaccination among cancer patients and healthcare workers. Abbreviations: CP: Cancer patients, HCW: Healthcare workers. Conclusion. In this study, both CPs and HCWs showed an adequate response to vaccination;however, CPs had lower anti-S Abs titers and a faster decline over time. Based on our results, new strategies should be assessed to sustain the humoral response to vaccination and thus decrease the COVID-19 burden among the oncologic population.

Secondary bacterial infection in hospitalized COVID-19 patients. Experience in Colombia, South America

Background. Secondary infections are common among severe COVID-19 patients, increasing complications and mortality risk. These infections are not well characterized in Latin America and the Caribbean. Methods. A cross-sectional observational study of adult patients with COVID-19 admitted to the hospital Fundacion Valle del Lili in Cali-Colombia from March 2020 to March 2021. Demographic data, clinical characteristics, laboratory parameters, and clinical outcomes were collected. We describe secondary infection, antibiotic therapy, and antibiotic resistance profiles. Secondary infection was defined if the diagnosis occurred >=48 hours after hospital admission for COVID-19. Results. A total of 2138 patients with COVID-19 were analyzed;350 (16.3%) presented secondary infection. 60% were male;the median age was 65 years [IQR: 55-72]. Glucocorticoid therapy was indicated in 335 patients (96.3%). 281 received high doses and 54 low doses. Bacterial infections were the most common, affecting 81.3 % of patients, followed by fungal (14.4%) and viral (4.3%) infections. Most bacterial isolates were orotracheal secretion, blood, urine, and bronchoalveolar lavage fluid culture. The three most frequently identified bacteria were Klebsiella pneumoniae, Staphylococcus aureus, and Pseudomonas aeruginosa. Most of the initial isolates were not antibiotic-resistant (75-89.7%). Empiric antibiotic therapy was indicated in 346 patients (98.9%), 268 received carbapenems (76.6%), 267 Vancomycin (76.3%), and 233 cefepime (66.6%). Of the 350 patients, 327 (93.4%) required management in the intensive care unit, and overall mortality was 35.4% (124/350). Conclusion. Our results showed a lower frequency of secondary infection than previous reports;However, a high frequency of broad-spectrum antibiotics usage was found despite a high prevalence of non-resistant bacteria. Further studies are needed to establish the best approach for antibiotics therapy.

Dengue - SARS-CoV-2 co-infection: Experience in hospitalized patients during COVID-19 pandemic

Background. Dengue fever and COVID-19 co-infection constitute a significant public health concern in Latin America, becoming a clinical challenge to distinguish these two entities in early stages of the disease. Clinical outcomes of coinfected hospitalized patients have not been well established. Methods. A cross-sectional study was conducted. We included suspected patients diagnosed with COVID-19/dengue co-infection admitted at Hospital Fundacion Valle del Lili, Cali - Colombia, from March 2020 to March 2021. All dengue patients had positive NS1 and/or IgM dengue antibodies. SARS-CoV-2 infection was confirmed by RT-PCR or antigen rapid test from nasopharyngeal swab. Laboratory and clinical data were recollected from the clinical laboratory database, clinical charts, and institutional COVID-19 registry. Results. A total of 90 COVID-19 patients were included. 72 patients were confirmed only with COVID-19, and 18 with dengue co-infection. Most patients were male: 46 (63.9%) vs. 13 (72.2%). None of these study patients were vaccinated against COVID-19 or dengue. The median time from symptoms onset and the diagnosis was five days, and fever was the most common symptom for both groups. There were significant differences between COVID-19 patients and coinfected patients regarding presence of dyspnea (22.2% vs. 61.1%;p=0.003), desaturation (13.4% vs. 53.3%;p=0.002) and a higher neutrophil/lymphocyte ratio (NLR) (3.84 vs. 5.59;p = 0.038). The co-infection was associated with a worse presentation of the COVID-19 infection (p=0.002), an increased requirement of initial supplemental oxygen therapy (p=0.007), mechanical ventilation (p=0.0004), ICU management at the admission (p=0.002), and ICU final management (p=0.002). Overall mortality in patients with co-infection was 44.4% vs. 6.9% in only COVID-19 infected patients (p< 0.001). Conclusion. Despite the pandemic era, the possibility of co-infection of these two entities must be considered. Admitted coinfected patients were associated with worse clinical outcomes and higher mortality. According to our results, patients with co-infection present with severe respiratory symptoms and an elevated NLR. The impact of the Covid 19 vaccination on this coinfection is unknown.

Discussion-Oriented Teaching in the Digital Classroom: Teachers' Collaborative Adaptation in the Face of Disruption

We examine how a researcher-practitioner research group collaborated to adapt noticing practices in the face of disruptions brought on by the COVID-19 pandemic. We used a progress monitoring tool and cognitive field notes to support teacher partners' systematic reflection and to gauge teacher learning. Initial findings suggest these tools helped identify tensions around implementing online class discussions. We highlight the process the teacher partners engaged in as they re-conceptualized engagement, participation, and interaction. © ISLS.

Child psychiatric emergency visits during the COVID-19 pandemic

Introduction: Paediatric and adult psychiatric emergency department (ED) visits decreased during the initial COVID-19 pandemic outbreak. Long-term consequences of the pandemic will include increases in mental healthcare needs especially among especially vulnerable groups such as children and adolescents. Objective(s): This study examined changes in the number of overall and diagnosis-specific mental healthEDvisitsamongpatients aged<18 years following onset of the COVID-19 pandemic inMadrid, Spain. Method(s): We used electronic health records to extract the monthly numbers of total and diagnosis-specific mental health ED visits among patients aged <18 years, between October 2018 and April 2021, to La Paz University Hospital. We conducted interrupted time-series analyses and compared trends before and after the day of the first ED COVID-19 case (1st March 2020). Result(s): In March 2020, there was a marked initial decrease of -12.8 (95%CI -21.9, -7.9) less monthly mental health ED visits. After April 2020, there was a subsequent increasing trend of 3.4 (95%CI 2.6, 4.2) additional monthly mental health ED visits. Conclusion(s): After onset of the COVID-19 pandemic, there was an increase in paediatric psychiatric ED visits, especially due to suicide-related reasons. These data reinforce the crucial role of the ED in the management of acute mental health problems among youth and highlight the need for renovated efforts to enhance access to care outside of and during acute crises during the pandemic and its aftermath.

Online teaching in COVID-19 times. Student satisfaction and analysis of their academic performance

Online teaching has grown exponentially as a result of COVID-19. Universities and teaching institutions the world over have had to adapt their curricula to this new teaching and learning model. The main goal of this study is to analyse various teaching methodologies used on a sample of university students to analyse their effectiveness in terms of satisfaction, competencies and academic performance. The results suggest that methodologies that include greater student-teacher interaction or the use of videoconferencing for classes and problem-solving help to raise student satisfaction. Students also positively assess online teaching as it allows them to acquire new competencies and even to identify business opportunities. The online evaluation method used also seems to have been appropriate, as it led students to obtain better grades than in face-to-face teaching contexts. The study offers several implications for university teachers of Social Sciences who wish to adopt this type of teaching method.

Redefining American Dance in the Classroom: Responsibility to Racial Justice

After what was eighteen months of isolation and remote learning for some due to the COVID-19 global pandemic, it is imperative that dance classroom spaces become community spaces united in solidarity for all. Calling attention toward the racism systemically ingrained in the American dance legacy serves as an impetus to eliminate that racism while transforming American dance education into a sincerely American (multicultural) dance experience that is better informed, empathetic, and equitable. This essay based on literature in the fields of dance, education, and social justice discusses the racism embedded in America and American dance, the conglomeration of cultures and identities that inherently forge American dance, the need to see and understand thyself and others in the classroom, and methods for curricula diversification. © 2022, Pennsylvania State University Libraries.

Seroprevalence of SARS-CoV-2 in Health-care Personnel from the State of Guanajuato, Mexico: A Cross-Sectional Study

Guanajuato state in Mexico has high frequency of confirmed cases of COVID-19. Health-care workers are the most exposed to contagion due to contact with patients infected by SARS-CoV-2. The objective was to know the seroprevalence of antibodies (IgG) anti-SARS-CoV-2 in health-care workers from Secretary of Health from Guanajuato State. It was a cross-sectional, retrolective study, using database from the ENSERO-COVID program. It was recollected data about exposure in work and in community by contact with confirmed cases of COVID-19. The anti-SARS-CoV IgG antibody titer was determined, considering 1.4 or higher as positive. It used Chi squared test to show relationship between variables, Z for two proportions to test hypotheses and logistic regression for show the effect of exposure and test positive for antibodies. 4,047 registries were reviewed, 376 (9.29%) were positive for the presence of SARSCoV-2 antibodies. There is an association between the type of work unit (type determined by hospitalizing COVID-19 patients or not) with seropositivity (P <0.05). There was no effect of performance areas to be seropositive. Community exposure had an effect on being seropositive OR = 1.44 (1.17 - 1.79). Training in the proper use of personal protective equipment had a protective effect on being seropositive with OR = 0.79 (0.64 -0.99). Exposure in the community to a confirmed case to SARS-CoV-2 is found to have a significant association with the presence of anti-SARS-CoV-2 antibodies. Training in the proper use of personal protection equipment is a protector against SARS-CoV-2 infection. There is a significant association between the type of unit and the presence of anti-SARS-CoV-2 antibodies. Given the increase in the number of confirmed cases of SARS-CoV-2, it is vitally important that health workers adequately protect themselves both at the community and workplace level.

Children Suffer Too: Emotional Suffering in Children during the Covid-19 Pandemic

This research aimed to investigate how students in the Initial Years of Ensino Fundamental feel in the pandemic context. The objectives were to identify the frequency of situations in which there are signs of emotional distress in children and to verify whether there is a significant relationship between emotional distress and sociodemographic aspects (race, gender, own cell phone). A total of 1041 children from the 4th and 5th grades of Ensino Fundamental participated in the research. The instrument used for this verification was a questionnaire, containing sociodemographic aspects (ethnic-racial origin, gender, economic profile and access to communication resources) and situations related to emotional distress. The data found show that children have shown both feelings and behaviors that indicate emotional distress (fear, anxiety, loneliness, self-mutilation) and also that there are significant differences in emotional distress scores related to gender and ethnic-racial origin.

Emotional Suffering in Teenagers during the Covid-19 Pandemic

The coronavirus (Covid-19) pandemic represented a challenge to physical and emotional health for adolescents subjected to almost two years of social isolation, restricted to family life and prevented from being in school. This article presents data from the pandemic associated with emotional distress among adolescents and the impact of restricted school life in this period. This is an exploratory, descriptive research, whose objective was to identify the frequency of situations in which there are signs of emotional distress in adolescents and to compare the scores found between demographic profile issues (race, gender and smartphone use). A total of 1,991 adolescents participated in the sample, students from two directorates of the Sao Paulo state public education network. The investigation instrument was built from a broad literature review in the form of a questionnaire with closed questions, divided into two parts: the first, containing 13 questions about the student's profile and, the second, with 21 questions, about signs of emotional suffering. From the quantitative analysis, the results found highlight a higher score of emotional distress among adolescent girls and black students and point to the urgency of actions that provide welfare and the learning of assertive forms of conflict resolution, as well as the urgency of spaces for expression of feelings by students.
