Lung ultrasound in the diagnosis of serious lesions caused by the SARS-CoV-2 virus

Introduction: Lung ultrasound is a technique that provides very useful information in the diagnostic approach of patients with SARS-CoV-2 virus infection. The infiltrations detected in the pulmonary ultrasound may suggest pulmonary edema, infarction or lobar pneumonia, which offers high availability and the possibility of evaluating the patient in situ. A search was carried out in the engines: Google Scholar, National Library of Medicine PudMed, SciELO regional since 2019. The search strategy used the terms: pulmonary ultrasound / technique, diagnostic methods, pathological findings. In the bibliographic search carried out, 24 articles were found related to pathological findings in lung ultrasound and the diagnostic value of lung lesions. Objective: To describe the fundamental findings of lung ultrasound in the diagnosis of serious lesions caused by the SARS-CoV-2 virus. Development: Studies reported similar precision of lung ultrasound compared to chest tomography in detecting lung abnormalities, their relationship to severity status, and risk stratification in critically ill patients with SARS-CoV-2. Conclusions: Ultrasound allows a constant and non-invasive evaluation of lung lesions caused by the SARS-CoV-2 virus, allows a correct identification of the severity and its evolution. It is a diagnostic method that reduces the risk of exposure to ionizing radiation, increasing safety for critically ill patients. © 2023, Editorial Ciencias Medicas. All rights reserved.

Pathogen sensing device based on 2D MoS2/graphene heterostructure

In this work we propose a new methodology for selective and sensitive pathogen detection based on a 2D layered heterostructured biosensing platform. As a proof of concept, we have chosen SARS-CoV-2 virus because the availability of new methods to detect this virus is still a great deal of interest. The prepared platform is based on the covalent immobilization of molybdenum disulphide functionalized with a diazonium salt (f-MoS2) onto graphene screen-printed electrodes (GPH SPE) by electrografting of the diazonium salt. This chemistry-based method generates an improved heterostructured biosensing platform for aptamer immobilization and aptasensor development. Electrochemical impedance spectroscopy (EIS) is used to obtain the signal response of the device, proving the ability of the sensor platform to detect the virus. SARS-CoV-2 spike RBD recombinant protein (SARS-CoV-2 S1 protein) has been detected and quantified with a low detection limit of 2.10 fg/mL. The selectivity of the developed biosensor has been confirmed after detecting the S1 protein even in presence of other interfering proteins. Moreover, the ability of the device to detect SARS-CoV-2 S1 protein has been also tested in human serum samples.

Mobile Health Requirements for the Occupational Health Assessment of Health Care Professionals: Delphi Study.

BACKGROUND: In recent years, owing to the COVID-19 pandemic, awareness of the high level of stress among health care professionals has increased, and research in this area has intensified. Hospital staff members have historically been known to work in an environment involving high emotional demands, time pressure, and workload. Furthermore, the pandemic has increased the strain experienced by health care professionals owing to the high number of people they need to manage and, on many occasions, the limited available resources with which they must carry out their functions. These psychosocial risks are not always well dealt with by the organization or the professionals themselves. Therefore, it is necessary to have tools to assess these psychosocial risks and to optimize the management of this demand from health care professionals. Digital health, and more specifically, mobile health (mHealth), is presented as a health care modality that can contribute greatly to respond to these unmet needs. OBJECTIVE: We aimed to analyze whether mHealth tools can provide value for the study and management of psychosocial risks in health care professionals, and assess the requirements of these tools. METHODS: A Delphi study was carried out to determine the opinions of experts on the relevance of using mHealth tools to evaluate physiological indicators and psychosocial factors in order to assess occupational health, and specifically, stress and burnout, in health care professionals. The study included 58 experts with knowledge and experience in occupational risk prevention, psychosocial work, and health-related technology, as well as health professionals from private and public sectors. RESULTS: Our data suggested that there is still controversy about the roles that organizations play in occupational risk prevention in general and psychosocial risks in particular. An adequate assessment of the stress levels and psychosocial factors can help improve employees' well-being. Moreover, making occupational health evaluations available to the team would positively affect employees by increasing their feelings of being taken into account by the organization. This assessment can be improved with mHealth tools that identify and quickly highlight the difficulties or problems that occur among staff and work teams. However, to achieve good adherence and participation in occupational health and safety evaluations, experts consider that it is essential to ensure the privacy of professionals and to develop feelings of being supported by their supervisors. CONCLUSIONS: For years, mHealth has been used mainly to propose intervention programs to improve occupational health. Our research highlights the usefulness of these tools for evaluating psychosocial risks in a preliminary and essential phase of approaches to improve the health and well-being of professionals in health care settings. The most urgent requirements these tools must meet are those aimed at protecting the confidentiality and privacy of measurements.

Short telomeres in alveolar type II cells associate with lung fibrosis in post COVID-19 patients with cancer.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the coronavirus disease 2019 (COVID-19) pandemic. The severity of COVID-19 increases with each decade of life, a phenomenon that suggest that organismal aging contributes to the fatality of the disease. In this regard, we and others have previously shown that COVID-19 severity correlates with shorter telomeres, a molecular determinant of aging, in patient's leukocytes. Lung injury is a predominant feature of acute SARS-CoV-2 infection that can further progress to lung fibrosis in post-COVID-19 patients. Short or dysfunctional telomeres in Alveolar type II (ATII) cells are sufficient to induce pulmonary fibrosis in mouse and humans. Here, we analyze telomere length and the histopathology of lung biopsies from a cohort of alive post-COVID-19 patients and a cohort of age-matched controls with lung cancer. We found loss of ATII cellularity and shorter telomeres in ATII cells concomitant with a marked increase in fibrotic lung parenchyma remodeling in post- COVID-19 patients compared to controls. These findings reveal a link between presence of short telomeres in ATII cells and long-term lung fibrosis sequel in Post-COVID-19 patients.

Frequency and Referral Patterns of Neural Antibody Studies During the COVID-19 Pandemic: Experience From an Autoimmune Neurology Center.

OBJECTIVE: To determine whether the frequency of paraneoplastic or autoimmune encephalitis antibodies examined in a referral center changed during the COVID-19 pandemic. METHODS: The number of patients who tested positive for neuronal or glial (neural) antibodies during pre-COVID-19 (2017-2019) and COVID-19 (2020-2021) periods was compared. The techniques used for antibody testing did not change during these periods and included a comprehensive evaluation of cell-surface and intracellular neural antibodies. The chi-square test, Spearman correlation, and Python programming language v3 were used for statistical analysis. RESULTS: Serum or CSF from 15,390 patients with suspected autoimmune or paraneoplastic encephalitis was examined. The overall positivity rate for antibodies against neural-surface antigens was similar in the prepandemic and pandemic periods (neuronal 3.2% vs 3.5%; glial 6.1 vs 5.2) with a mild single-disease increase in the pandemic period (anti-NMDAR encephalitis). By contrast, the positivity rate for antibodies against intracellular antigens was significantly increased during the pandemic period (2.8% vs 3.9%, p = 0.01), particularly Hu and GFAP. DISCUSSION: Our findings do not support that the COVID-19 pandemic led to a substantial increase of known or novel encephalitis mediated by antibodies against neural-surface antigens. The increase in Hu and GFAP antibodies likely reflects the progressive increased recognition of the corresponding disorders.

Navigating a Context of Severe Uncertainty: The Effect of Industry Unsafety Signals on Employee Well-being During the COVID-19 Crisis

Complex disaster situations like the 2019 novel coronavirus (COVID-19) create macro-level contexts of severe uncertainty that disrupt industries across the globe in unprecedented ways. While occupational health research has made important advances in understanding the effects of occupational stressors on employee well-being, there is a need to better understand the employee well-being implications of severe uncertainty stemming from macro-level disruption. We draw from the Generalized Unsafety Theory of Stress (GUTS) to explain how a context of severe uncertainty can create signals of economic and health unsafety at the industry level, leading to emotional exhaustion through paths of economic and health anxiety. We integrate recent disaster scholarship that classifies COVID-19 as a transboundary disaster and use this interdisciplinary perspective to explain how COVID-19 created a context of severe uncertainty from which these effects unfold. To test our proposed model, we pair objective industry data with time-lagged quantitative and qualitative survey responses from 212 employees across industries collected during the height of the initial COVID-19 response in the United States. Structural equation modeling results indicate a significant indirect effect of industry COVID-19 unsafety signals on emotional exhaustion through the health, but not economic, unsafety path. Qualitative analyses provide further insights into these dynamics. Theoretical and practical implications for employee well-being in a context of severe uncertainty are discussed.

Use of high-flow cannula in pediatric patients with respiratory failure: A prospective cohort study in three high-altitude hospitals.

Background and Aims: Acute respiratory failure (ARF) is a common cause of morbimortality, and a frequent reason for admission to the pediatric intensive care unit (PICU). It requires a high-flow oxygen device as treatment. Our aim is to determine the frequency and main indications for the use of high-flow nasal cannula (HFNC), and the prevalence of HFNC failure and its main causes, in three hospitals. Methods: It is a multicenter prospective cohort study, developed in three hospitals in Bogota. Eligible patients were children older than 1 month and younger than 18 years who presented ARF and required management with an HFNC. The study was carried out between April 2020 and December 2021. The follow-up was carried out at 1, 6, and 48 h after starting the management. Results: Of 685 patients included in the study, 296 developed ARF. The prevalence of patients with ARF who required management with HFNC was 48%. The frequency of the pathologies that cause the ARF was: Bronchiolitis was the most frequent pathology (34.5%), followed by asthmatic crisis (15.5%) and pneumonia (12.7%). The average time of use of HFNC was 81.6 h. Regarding treatment failure with HFNC, 15 patients presented torpid evolution and required invasive mechanical ventilation, with a prevalence of therapeutic failure of the HFNC of 10.6%. Conclusion: The use of HFNC is more frequent in patients with bronchiolitis, in children under 2 years of age and in males, which is in line with what has been reported in the literature. In addition, the failure rate of HFNC is low (10.6%), and it may be useful in other pathologies besides bronchiolitis, such as asthma, pneumonia, among others. It opens the possibility to continue evaluating the role of HFNC in pediatric pathology in new studies.

The deadly impact of COVID-19 among children from Latin America: The case of Ecuador.

Background: The SARS-CoV-2 pandemic remains a critical global health concern, with older adults being the most vulnerable group. Nonetheless, it is crucial to recognize that COVID-19 has caused numerous deaths in children worldwide. Emerging evidence indicates that infants and breastfeeding children, particularly those aged below one year, face a greater risk of hospitalization and mortality than older children with COVID-19. Objective: This study aimed to describe the epidemiology of COVID-19 among children during the early phase of the pandemic in Ecuador. Methods: We conducted a country-wide population-based analysis of the epidemiology of COVID-19, using incidence and mortality data reported from Ecuador between February 15, 2020 and May 14 2021. Measurements of frequency, central tendency, dispersion, and absolute differences were calculated for all categorical and continuous variables. Results: At least 34,001 cases (23,587 confirmed cases, 5,315 probable and 5,099 suspected) and 258 COVID-19 related deaths have been reported among children in Ecuador during the first 16 months of the pandemic. The overall incidence rate was 612 cases per 100,000 children, the mortality rate was 3 per 100,000, while the case fatality rate was 0.76%. The highest risk group for infection was children and adolescents between 15 and 19 years of age; however, the highest mortality rate occurred in children under one year of age. The largest provinces, such as Pichincha, Guavas and Manabí, were the ones that reported the highest number of cases, 27%, 12.1% and 10.8%, respectively. Conclusions: This study is the first to report on COVID-19 epidemics among children in Ecuador. Our findings reveal that younger children have a lower risk of SARS-CoV-2 infection, but a higher risk of mortality compared to older children and adolescents. Additionally, we observed significant disparities in infection rates and outcomes among children living in rural areas, those with comorbidities, and those from indigenous ethnic groups.

COVID-19, Didactic Practices, and Representations Assumed by Preservice Teachers at Universidad Tecnica del Norte-Ecuador

As an alternative for university students to continue their professional training during the COVID-19 pandemic, higher education institutions implemented virtual learning modalities. In this context, it was proposed to determine the social representations assumed by university students who are pursuing their studies as future educators. It is presumed that representations related to didactic practices are composed of content (knowledge, skills, and attitudes) and organization (central core and representational system). This is an ethnographic study, with an available nonprobabilistic sample of 227 students from the primary education major at Universidad Tecnica del Norte. Verbal association techniques and documentary research were used for information collection. To analyze the data, the IRaMuTeQ software (R interface for texts and questionnaire multidimensional analysis) was used. Two types of analyses were conducted: hierarchical classification and factorial correspondence. In conclusion, a virtuality with difficulties and a careful and responsible face-to-face modality are expressed as meanings associated to the representations, both of which require qualitative changes. Regarding the organization, didactic practice complementarity is assumed to be integrated in a hybrid learning modality.

COVID-19 and Psychosocial Well-Being: Did COVID-19 Worsen U.S. Frontline Healthcare Workers' Burnout, Anxiety, and Depression?

Healthcare workers are highly regarded for their compassion, dedication, and composure. However, COVID-19 created unprecedented demands that rendered healthcare workers vulnerable to increased burnout, anxiety, and depression. This cross-sectional study assessed the psychosocial impact of COVID-19 on U.S. healthcare frontliners using a 38-item online survey administered by Reaction Data between September and December 2020. The survey included five validated scales to assess self-reported burnout (Maslach Summative Burnout Scale), anxiety (GAD-7), depression (PHQ-2), resilience (Brief Resilience Coping Scale), and self-efficacy (New Self-Efficacy Scale-8). We used regression to assess the relationships between demographic variables and the psychosocial scales index scores and found that COVID-19 amplified preexisting burnout (54.8%), anxiety (138.5%), and depression (166.7%), and reduced resilience (5.70%) and self-efficacy (6.5%) among 557 respondents (52.6% male, 47.5% female). High patient volume, extended work hours, staff shortages, and lack of personal protective equipment (PPE) and resources fueled burnout, anxiety, and depression. Respondents were anxious about the indefinite duration of the pandemic/uncertain return to normal (54.8%), were anxious of infecting family (48.3%), and felt conflicted about protecting themselves versus fulfilling their duty to patients (44.3%). Respondents derived strength from their capacity to perform well in tough times (74.15%), emotional support from family/friends (67.2%), and time off work (62.8%). Strategies to promote emotional well-being and job satisfaction can focus on multilevel resilience, safety, and social connectedness.

Strategic Planning and Economic Recovery in the Post-Pandemic of the Automotive Sector

This research analyzes from three indicators the impact suffered by the automotive sector in Ecuador after the pandemic and proposes a generic model for the design and creation of strategic planning that helps companies in the sector to adapt to the new context and reactivate their activities in the face of new consumption habits,o maintain its validity in the market. The methodology used was quantitative, the method was deductive of explanatory scope with a non-experimental cross-sectional design, since historical documentary sources published by the Association of Automotive Companies of Ecuador (AEADE) were used. According to the results obtained with this study, it was determined that in 2022, after the pandemic, there was an increase in the number of imported vehicles, a decrease in the number of vehicles sold that were assembled in the country, and there is no significant difference in the number of imported vehicles marketed in the country. In any of these cases, the implementation or updating of appropriate strategic planning in organizations that develop activities in the automotive field will allow the best performance of these and their greater validity in the market. Given these effects, the Government needs to support policies for the preservation of capacities and resources, as well as their subsequent strengthening to promote post-pandemic recovery. The model proposed as a product of the study is composed of 9 phases that allow to develop and apply strategic planning in companies in the automotive sector, this model arises from the review and adoption of the best practices found in four of the most used modelsto the global novel.Copyright © 2023, Anka Publishers.

Lyrics Training: An E-learning Approach to Improve Listening Skills

Due to the COVID-19 pandemic, educational agents have been forced to apply strategies and methodologies and use new technological tools that allow them to continue with the teaching–learning processes. Because of this, the present research implements an innovative methodology to analyze the contribution of the Lyrics Training method in the development of listening skills for English language improvement. The experiment was carried out with high school seniors from an academic unit in the city of Ambato. A sample of 62 students was divided into two groups, an experimental group and a control group, each of 31 learners. When comparing both groups through a t-student test for independent samples, the results showed a p-value lower than 0.05 and a Cohen's d coefficient higher than 0.8, establishing that the teaching process through the Lyrics Training methodology is efficient. Finally, to verify if the Lyrics Training method is suitable for the selected experimental group, the usability scale (SUS) was applied, in which an average acceptance of more than 70 points was obtained, indicating that, in general terms, the Lyrics Training method through a web page is efficient for teaching the English language. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

MoCA-T as a remote assessment tool to determine cognitive impairment in patients with moderate to severe OSA

The COVID-19 pandemic has led to the emergence of technological tools that allow remote assessment on patients. The Montreal Cognitive Assessment Test Telephone Version (MoCA-T) is one of them. Considered as a telemedicine resource that allows remote cognitive screening in pandemic era and in the population with difficulties in accessing health centers. Mild cognitive impairment (MCI) is a common finding in patients with Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS). However, the application of telephone tests for cognitive screening has not been studied. To determine the frequency of cognitive deterioration through the application of MoCA-T as a remote screening test in patients with moderate and severe OSAHS is the main objective of this work. To do this, the MoCA-T test was applied to 104 patients with polysomnographic diagnostic capabilities for moderate and severe OSAHS between ages 18 and 65, excluding patients with comorbidities that affect cognitive ones. Abnormal MoCA-T results were obtained in 43% of patients, with the cognitive domains of memory and attention being the most affected. Finally, abnormal MoCA-T results correlated with self-perception of memory difficulties, being more frequently altered in those who manifest cognitive complaints. The MoCA-T test could be a brief, validated and feasible technological tool for cognitive screening of patients with OSAHS in times of pandemic and in patients with care barriers.Copyright © 2023 Sociedad Neurologica Argentina

MoCA-T como herramienta de evaluación remota para precisar deterioro cognitivo en pacientes con SAHOS moderado a severo MoCA-T as a remote assessment tool to determine cognitive impairment in patients with moderate to severe OSA

La pandemia de COVID-19 ha dado lugar al surgimiento de herramientas tecnológicas que permiten la valoración de pacientes de forma remota. La prueba de evaluación cognitiva de Montreal, versión telefónica (MoCA-T), es una de ellas. Se considera como un recurso de la telemedicina que permite la tamización cognitiva a distancia en épocas de pandemia y en la población con dificultades en el acceso a los centros de salud. El deterioro cognitivo leve (DCL) es un hallazgo usual en pacientes con síndrome de apnea-hipopnea obstructiva del sueño (SAHOS);sin embargo, no se ha estudiado la aplicación de pruebas telefónicas para su tamización cognitiva. El objetivo principal de este trabajo es determinar la frecuencia de deterioro cognoscitivo mediante la aplicación de MoCA-T como prueba de tamización remota en pacientes con SAHOS moderado y severo. Para ello, se aplicó la prueba de MoCA-T en 104 pacientes entre 18 y 65 años con diagnóstico polisomnográfico de SAHOS moderado y severo, excluyéndose a pacientes con comorbilidades que afectasen las capacidades cognoscitivas. Se obtuvieron resultados anormales de MoCA-T en el 43% de los pacientes, siendo los dominios cognitivos de la memoria y la atención los más comúnmente afectados. Finalmente, los resultados anormales de MoCA-T se correlacionaron con la autopercepción de las dificultades en la memoria, estando más frecuentemente alterada en quienes manifestaron quejas cognitivas. La prueba MoCA-T podría ser una herramienta tecnológica breve, validada y factible para realizar el tamizaje cognitivo de pacientes con SAHOS en épocas de pandemia y en pacientes con barreras asistenciales.

Minimal purification method enables developability assessment of recombinant proteins.

Analytical characterization of proteins is a critical task for developing therapeutics and subunit vaccine candidates. Assessing candidates with a battery of biophysical assays can inform the selection of one that exhibits properties consistent with a given target product profile (TPP). Such assessments, however, require several milligrams of purified protein, and ideal assessments of the physicochemical attributes of the proteins should not include unnatural modifications like peptide tags for purification. Here, we describe a fast two-stage minimal purification process for recombinant proteins secreted by the yeast host Komagataella phaffii from a 20 mL culture supernatant. This method comprises a buffer exchange and filtration with a Q-membrane filter and we demonstrate sufficient removal of key supernatant impurities including host-cell proteins (HCPs) and DNA with yields of 1-2 mg and >60% purity. This degree of purity enables characterizing the resulting proteins using affinity binding, mass spectrometry, and differential scanning calorimetry. We first evaluated this method to purify an engineered SARS-CoV-2 subunit protein antigen and compared the purified protein to a conventional two-step chromatographic process. We then applied this method to compare several SARS-CoV-2 RBD sequences. Finally, we show this simple process can be applied to a range of other proteins, including a single-domain antibody, a rotavirus protein subunit, and a human growth hormone. This simple and fast developability methodology obviates the need for genetic tagging or full chromatographic development when assessing and comparing early-stage protein therapeutics and vaccine candidates produced in K. phaffii.

Systemic lupus erythematosus flare during SARS-CoV-2 infection: Report of 3 cases presented during the fourth wave of the pandemic in Colombia.

BACKGROUND: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus has become a worldwide pandemic since first discovered in 2019. Systemic lupus erythematosus (SLE) flare has been reported in the post-infectious period. In Colombia, the fourth pandemic wave started at the beginning of 2022 when we observed flare of 3 SLE patients during active infection. CASE PRESENTATION: We describe 3 patients with inactive SLE, who presented coronavirus disease 2019 and severe flare in early 2022, 2 patients with nephritis and 1 with severe thrombocytopenia. All patients had increase of antinuclear and anti-DNA antibody titers and complement consumption. CONCLUSIONS: Three cases with SLE flare concomitant with active SARS-CoV-2 infection were different from others reported earlier in the pandemic with post-infectious flare.

COVID-19 in children and the influence on the employment activity of their female caregivers: A cross sectional gender perspective study.

Introduction: During the COVID-19 pandemic, women disproportionately assume more unpaid activities, affecting their employment. Objective: Describe the influence of COVID-19 on the employment of caregivers of children and adolescents from a gender perspective. Methods: Cross-sectional study in three high-complexity hospitals in Bogotá, Colombia from April 2020 to June 2021. A subsample of the FARA cohort was taken, including those patients with a positive test for SARS-COV2. We took as our analysis category children older than 8 years and younger than 18 years who had a positive SARS-COV2 test, as well as, caregivers of all children with a positive SARS-COV2 test. This subsample was drawn from the FARA cohort. A survey was applied to them. We carried out a descriptive and stratified analysis by age group, educational, and socioeconomic level. Results: We included 60 surveys of caregivers and 10 surveys of children. The main caregiver in 94.8% of the cases was a female. At the beginning of the pandemic, 63.3% of the caregivers were employed, and 78.9% of those lost their employment. The vast majority of these caregiver were women (96.6%, n = 29). A predominance of loss of work activity was documented in caregivers of children in early childhood 66.6% (n = 20), with lower education 66.6% (n = 20), and from lower strata 56.6% (n = 17). Conclusion: Caregivers of children with COVID-19 with low educational levels and lower socioeconomic conditions, as well as those with children under 5 years showed greater likelihood of employment loss between the interviewed subsample.

Nurses' Perceptions of Ethical Conflicts When Caring for Patients with COVID-19.

The COVID-19 pandemic has caused ethical challenges and dilemmas in care decisions colliding with nurses' ethical values. This study sought to understand the perceptions and ethical conflicts faced by nurses working on the frontline during the first and second waves of the COVID-19 pandemic and the main coping strategies. A qualitative phenomenological study was carried out following Giorgi's descriptive phenomenological approach. Data were collected through semi-structured interviews until data saturation. The theoretical sample included 14 nurses from inpatient and intensive care units during the first and second waves of the pandemic. An interview script was used to guide the interviews. Data were analyzed following Giorgi's phenomenological method using Atlas-Ti software. Two themes were identified: (1) ethical conflicts on a personal and professional level; and (2) coping strategies (active and autonomous learning, peer support and teamwork, catharsis, focusing on care, accepting the pandemic as just another work situation, forgetting the bad situations, valuing the positive reinforcement, and humanizing the situation). The strong professional commitment, teamwork, humanization of care, and continuous education have helped nurses to deal with ethical conflicts. It is necessary to address ethical conflicts and provide psychological and emotional support for nurses who have experienced personal and professional ethical conflicts during COVID-19.
