From center stage to backdrop: thematization and generic news frames of the extended pandemic in Argentine digital newspapers

If there is one thing we can be sure about the COVID-19 pandemic, it is that it caused an irruption of such magnitude throughout the world that the resonances of the multiple and varied changes it generated have yet to be seen. In relation to communication processes, the demand for information in real time increased and the media took center stage, especially in an initial period when the possibilities of intersubjective contrasts between people were diminished by the confinements. But this was not a constant: as the pandemic spread over time, it lost its novelty character and went from center stage to backdrop in media coverage. This research describes the thematic shifts and the predominant frames that La Nación, Clarín (in its digital versions) and Infobae deployed in their coverage of the pandemic between 2020 and 2022. Framed in the contributions of the agenda setting and framing theories, this paper starts with a quantitative content analysis and compares four specific time frames (April 2020, October 2020, May 2021 and January 2022), chosen for having represented significant peaks in the development of the pandemic in national health terms. The analysis shows that the concentration of the health issue, as well as the prominence of the variables that make up the morality and human interest frames were diluted over time, making the frames in the coverage of the issue less compact and more dispersed. © 2023 University of Piura.

SARS-CoV-2 INFECTION AMONG PERSONS WHO INJECT DRUGS AND THEIR PARTNERS IN KENYA

Background: Despite increased social vulnerability and barriers to care, there has been a paucity of data on SARS-CoV-2 incidence among key populations in sub-Saharan Africa. We seek to characterize active infections and define transmission dynamics of SARS-CoV-2 among people who inject drugs (PWID) and their sexual and injecting partners from Nairobi and the coastal region in Kenya. Method(s): This was a nested cross-sectional study of SARS-CoV-2 infection from April to July 2021 within a cohort study of assisted partner services for PWID in Kenya. A total of 1000 PWID and their partners (500 living with and 500 living without HIV) were recruited for SARS-CoV-2 antibody testing, of whom 440 were randomly selected to provide self-collected nasal swabs for real-time PCR testing. Whole genome sequencing (WGS) was completed on a limited subset of samples (N=23) with cycle threshold values 32.0. Phylogenetic tree construction and analysis was performed using the Nextstrain pipeline and compared with publicly available SARS-CoV-2 sequences from GenBank. Result(s): A total of 438 (99.5%) participants provided samples for SARS-CoV-2 PCR testing. Median age was 37 (IQR 32-42);128 (29.2%) were female;and 222 (50.7%) were living with HIV. The overall prevalence of SARS-CoV-2 infection identified by RT-PCR was 86 (19.6%). In univariate analyses, there was no increased relative risk of SARSCoV- 2 infection related to positive HIV status, frequenting an injection den, methadone treatment, unstable housing, report of any high-risk exposure, or having a sexual or injecting partner diagnosed with COVID-19 or who died from COVID-19 or flu-like illness. Eight samples were successfully sequenced via WGS and classified as WHO variants of concern: 3 Delta, 3 Alpha, and 2 Beta. Seven were classified into clades predominantly circulating in Kenya during 2021. Notably, two sequences were identical and matched identically to another Kenyan sequence, which is consistent with, though not indictive of, a transmission linkage. Conclusion(s): Overall, the risk of SARS-CoV-2 infection in this population of PWID and their partners was not significantly associated with risk factors related to injection drug use. At a genomic level, the SARS-CoV-2 strains in this study were consistent with contemporary Kenyan lineages circulating during the time and not unique to PWID. Prevention efforts, therefore, must also focus on marginalized groups for control given the substantial amount of mixing that likely occurs between populations.

Numerical and experimental study of aerosol dispersion in the Do728 aircraft cabin.

The dispersion of aerosols originating from one source, the 'index' passenger, within the cabin of the aircraft Do728 is studied experimentally using an aerosol-exhaling thermal manikin and in Reynolds-averaged Navier-Stokes simulations (RANS). The overall aim of the present study is the experimental determination of the aerosol spreading for the state-of-the-art mixing ventilation (MV) and to evaluate the potential of alternative ventilation concepts for controlling the aerosol spreading in RANS. For MV, the experiments showed that the ratio of inhaled to exhaled aerosol particles drops below 0.06% (volume ratio) for distances larger than two seat rows from the source. However, within a single row, the observed ratio is higher. Further, the dispersion is much weaker for a standing than for a seated index passenger. High air exchange rates and a well-guided flow prevent a dispersion of the aerosols in high concentrations over larger distances. Additionally, the positive effect of a mask and an increased air flow rate, and especially their combination are shown. In the complementary conducted RANS, the advantages of floor-based cabin displacement ventilation (CDV) which is alternative ventilation concept to MV, regarding spreading lengths and the dwell time of the aerosols in the cabin were determined. The obtained results also underline the importance of the flow field for the aerosol dispersion. Further, additional unsteady RANS (URANS) simulations of the short-term process of the initial aerosol cloud formation highlighted that the momentum decay of the breathing and the evaporation processes take place within a few seconds only.

Changes and Disparities in Nature Access During the COVID-19 Pandemic

Time in nature is associated with a range of physical and psychological benefits. These benefits tend to be unevenly distributed, with non-white and low-income communities often having lower access to nature than richer, more white neighborhoods. When the COVID-19 pandemic hit the United States in Spring 2020, changes in daily routines, restrictions on public nature access, and risk perceptions may have affected whether and how much people spent time in nature. We explore how nature access changed during the COVID-19 pandemic and how those changes were experienced by different demographic groups. We surveyed representative samples of California and New York residents (n = 2,036) in May and June of 2020 and examined differences in nature access and nature-related COVID restrictions and risks by gender, income and race. We find that, on average, the pandemic was associated with reductions in frequency of nature access and less time in nature for all respondents. However, these trends were greatest for women, people of color and people who are low-income. Moreover, the pandemic seems to have widened prior inequalities: low-income and non-white people accessed nature even less frequently and had fewer nature access options than they did prior to the pandemic. Given the disparities in broader pandemic impacts by gender, income, and race, these results further demonstrate the inequalities laid bare by COVID-19.

EVALUATION OF THE AT-HOME CAPSULE ENDOSCOPY (ACE) SERVICE AT UCLH: PRELIMINARY FINDINGS

Introduction UCLH has developed a modified 'At Home' Capsule endoscopy (ACE) service for patients undergoing capsule endoscopy where the entire procedure is completed at home through remote (telemedicine) assistance. This aimed to improve access to endoscopy services during the covid-19 pandemic. This a preliminary review of the ACE focusing on procedure safety, success rates and patient satisfaction. Methods Data on all ACE procedures at UCLH was looked at prospectively. Demographics, completion rates, and complication rates were recorded. All patients were asked to complete patient satisfaction questionnaires relating to the at home process (experience of the process, support from staff, expectations, tolerance of procedure, satisfaction, and preference for future investigations). Results 34 ACE procedures were looked at for this study. 13 were colon capsule endoscopies (CCE) and 21 small bowel capsule endoscopies (SBCE). Mean age of participants was 38 years and 17 (50%) were males. Indications were FIT positive (2.9%), iron-deficiency anaemia (14.7%), inflammatory bowel disease (61.7%) or investigation of other symptoms (20.6%). 31 (91.1%) procedures were successful- defined as a complete procedure with adequate bowel preparation. There were 3 failed ACEs (2= poor prep, 1= capsule not excreted). There were no complications and no need to convert the remote test to 'in-hospital'. 16 (47%) patient satisfaction questionnaires were returned. No patients found the procedure painful or embarrassing and 12 (75%) patients were not anxious prior to their procedure. On a satisfaction scale of 1-10, 12 patients (75%) scored ACE as ≥8. 13 (81.3%) patients would choose to have ACE vs inhospital CE. 12 (75%) patients would choose ACE as their preferred colonic investigation over CE in-hospital, colonoscopy, and CT colonography. Importantly, 87.5% of those patients had previously undergone a colonoscopy. Conclusions This is preliminary data on ACE, which shows a similar safety and success rate to standard practice in-hospital capsule endoscopy. 75% of patients preferred ACE over any other colonic investigation, suggesting potential increased acceptance by the public as a colorectal cancer screening test.

Global pandemic compels sport to move to esports: understanding from brand extension perspective. (Special Issue: Managing sport and leisure in the era of Covid-19.)

The COVID-19 outbreak leads to the sudden lockdown of sports businesses across the world. Due to the difficulty of generating sports content as usual amid the global pandemic, some sports organizations around the world, resort to esports. Concretely, sports organizations let their professional athletes compete virtually in video games to produce competitive entertainment for the audience. Such "mixed" competitive entertainment attracts a high spectatorship and significant social media attention. This commentary seeks to provide a research-based explanation of the phenomenon and predict future developments.

Changes in the nocturnal activity of birds during the covid–19 pandemic lockdown in a neotropical city

Changes in the nocturnal activity of birds during the COVID–19 pandemic lockdown in a neotropical city. The COVID–19 lockdown provided the opportunity to measure species biodiversity in urban environments under conditions divergent from regular urban rhythms. For 90 days, including weeks of strict lockdown and the subsequent relaxation of restrictions, we measured the presence and abundance of birds that were active at night at two sites in the city of Cali, Colombia. Our results show that species richness of nocturnal birds decreased 40 % to 58 % during the weeks with more human activity, adding further evidence to the biodiversity responses of the 'anthropause' on urban environments. © 2021 belongs to the authors.

PK-5 teacher perspectives on the design of remote teaching: pedagogies and support structures to sustain student learning online

The shift to emergency remote teaching during the COVID-19 pandemic has highlighted a need to develop technologies, resources, and strategies for teaching elementary grade learners online. This study uses online teacher inquiry as a form of practice-based knowledge production to identify and develop instructional practices and support structures for online teaching in grades PK-5. Six teachers of PK-5 classrooms in the United States participated in a teacher inquiry program as they transitioned from in-person to online teaching. Findings provide guidance to assist teachers and administrators in designing teaching and structures that support online learning in the elementary grades. © 2021 ISTE.

International collaboration during the COVID-19 crisis: autumn 2020 developments.

After the initial shock of the early months of the global COVID-19 pandemic, international collaboration in COVID-19 research continues to show aberrant patterns compared to coronavirus research in pre-COVID times. The most affected nations tend to produce the greatest number of coronavirus articles, with output closely coupled to the rate of infection. COVID-19 research has fewer nations and smaller teams than pre-COVID research, a trend which intensifies throughout the pandemic. The United States remains the single largest contributor to the global publication output, but contrary to China's dominance in the initial months of the pandemic, China's contribution falls as the national COVID-19 caseload drops. China-USA collaborations drop as the pandemic continues, perhaps due to China's reduced rate of publication on the topic, and perhaps due to political obstacles, or a combination of these factors.

Implementation of long-term non-participant reminders for flexible sigmoidoscopy screening.

The clinical effectiveness of screening is highly dependent on uptake. Previous randomised controlled trials suggest that non-participant reminders, which highlight the opportunity to re-book an appointment, can improve participation. The present analysis examines the impact of implementing these reminders within the English Flexible Sigmoidoscopy (FS) Screening Programme, which offers once-only FS screening to adults aged 55-59 years. We assessed the screening status of 26,339 individuals invited for once-only FS screening in England. A total of 10,952 (41.6%) had attended screening, and were subsequently ineligible. The remaining 15,387 had not attended screening, and were selected to receive a reminder, 1-2 years after their invitation. Descriptive statistics were used to assess the increase in uptake and the adenoma detection rate (ADR) of those who self-referred, six months after the delivery of the final reminder. Pearson's Chi-Square was used to compare the ADR between those who attended when invited and those who self-referred. Of the 15,387 adults eligible to receive a reminder, 13,626 (88.6%) were sent a reminder as intended (1,761 were not sent a reminder, due to endoscopy capacity). Of these, 8.0% (n = 1,086) booked and attended an appointment, which equated to a 4.1% increase in uptake from 41.6% at baseline, to 45.7% at follow-up. The ADR was significantly higher for those who self-referred, compared with those who attended when invited (13.3% and 9.5%, respectively; X 2 = 16.138, p = 0.000059). The implementation of non-participant reminders led to a moderate increase in uptake. Implementing non-participant reminders could help mitigate the negative effects of COVID-19 on uptake.
