ABSTRACT
With a selected focus on Europe and the Middle East and North Africa (MENA), Knowledge production in higher education presents a reflexive understanding of how Europe is taught and studied at MENA universities and how knowledge about the MENA is produced in Europe. This focus is based on the observation that higher education is rarely an apolitical space and an acknowledgement of how ‘every view is a view from somewhere'. It therefore explores the politics of institutes of higher education in view of often competing scholarly practices. Furthermore, it examines the historical evolution of French, German and Italian scholarship on the MENA;analyses the cases of Malta, Palestine and Turkey with their respective liminal characteristics in between the MENA and Europe, and how these impact on higher educational approaches to the study of the Other;considers critique as the driving force not only of the higher educational establishment but of liberal and illiberal contexts, with a specific focus on Denmark, the Netherlands and Egypt;and examines influences upon knowledge production including gender, the COVID-19 pandemic (with a focus on the UK and Syria) and think tanks. © Manchester University Press 2023.
ABSTRACT
Background: People living with HIV (PWH) may represent a high-risk group for adverse clinical outcomes from SARS-CoV-2. The duration of protection from SARS-CoV-2 and emerging variants of concern (VOC) infection in PWH following vaccination is unclear. Furthermore, the role of preexisting SARS-CoV-2 immune responses, likely acquired from prior exposure to circulating human coronaviruses (HCoVs), on vaccine-mediated immunity remains to be determined. Understanding the kinetics of immune responses to SARS-CoV-2 and VOCs, and the impact of preexisting SARS-CoV-2 immunity on vaccine-mediated immune responses will be critical in informing COVID-19 vaccination policies in PWH. Methods: In this sub-study of the Phase II/III COV002 trial (open-label, non-randomised clinical trial ID: NCT04400838), 54 HIV+ male participants on antiretroviral therapy (undetectable viral loads, CD4+ T cells >350 cells/ul) and 50 HIV-sex and age-matched controls received two doses of ChAdOx1 nCoV-19 (AZD1222) 4-6 weeks apart and were followed for 6 months. Immune responses to vaccination were determined by ELISA (standard and MSD assay), neutralisation, ACE-2 inhibition, IFNγ ELISpot, activation-induced marker (AIM) assay and T cell proliferation assays. Results: 6 months after vaccination, antibody IgG levels to SARS-CoV-2 S and RBD proteins, ACE-2 inhibition and T cell responses to S protein were significantly higher than baseline (Table 1). Both humoral and cell-mediated immunity waned over time, but with no significant difference compared with HIV-individuals vaccinated with the same regimen. T and B cell-mediated immune responses to VOCs α, β, γ, and δ were detectable, although at lower magnitudes than wild type. Prior exposure to circulating β coronavirus HKU1 and OC43 was associated with measurable proliferative SARS-CoV-2 T cell response at baseline and a higher magnitude of post-vaccine T cell responses. Conclusion: Our data demonstrate no significant difference in ChAdOx1 nCoV-19 vaccine-mediated immune responses by HIV status. For all groups, we show waning but detectable immune responses against SARS-CoV-2 and VOCs 6 months after vaccination supporting the on-going policy to vaccinate against SARS-CoV-2 and reinforces the argument for long-term monitoring of responses.
ABSTRACT
Introduction: The global pandemic of novel coronavirus disease 2019 (COVID-19) began in Wuhan, China in December 2019 and spread worldwide. This retrospective study summarizes clinical experience and analgo-sedation treatment used for this novel epidemic in an Italian ICU between February to May 2020. Methods: This is a retrospective trial of 72 patients with laboratory-confirmed SARS-CoV-2 infection (COVID-19) admitted to ICU between February15, 2020 and May 15, 2020. Main Outcomes are demographic, clinical data (age, sex, medical comorbidities, respiratory supports, positive end-expiratory pressure values (PEEP), fraction of inspired oxygen (FiO2), arterial partial pressure of oxygen (PaO2), sedatives and analgesic drugs, their dosage and way of administration, medical treatments and patients mortality), ventilation strategies, sedation management in ICUs and patient mortality. Results: The mean age of the 72 patients included in the study was 69 years (SD ±12), 77% were male. All patients required respiratory support and sedation management according to different techniques of ventilation: 100% received deep sedation (RASS-4) before intubation and invasive mechanical ventilation and 19% received light sedation (RASS-1) and noninvasive ventilation). Conclusions: Of the 72 patients admitted in ICUs, 92% died. A total of 608 patients admitted to the AORN dei Colli “Naples” with confirmed COVID-19. In this restrospective study we have analyzed 72 (out of 608) patients that were admitted to intensive care due to worsening clinical conditions. All patients required tracheal intubation and mechanical ventilation with deep sedation (RASS-4), while only 19% (patients required light sedation so RASS-1) were subsequentely swiched to light sedation because of the need of compliance with non-invasive ventilation. Sedation was obtained with propofol, remifentanil, midazolam and dexmedetomidine, according to hospital guidelines. ©2021 The Author(s). Published by MRE Press.
ABSTRACT
Studies concerning Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection in paediatrics are limited to children mainly selected from hospitals, where patients with complications and co-morbidities are managed. We aimed to describe the course of the Coronavirus Disease 2019 (COVID-19) in a population of children enrolled by place of residence, from diagnosis to recovery, with a long-term clinical and serological follow-up. We identified patients aged <14 years old living in the Turin Health District 3 who had SARS-CoV-2 detected in at least one nasopharyngeal swab from 1st March to 1st June 2020. Epidemiological and clinical features of SARS-CoV-2 infection were collected by way of a telephone inquiry. Enrolled patients were tested for SARS-CoV-2 serology in order to provide evidence of seroconversion and persistence of specific antibodies some time after the infection. A total of 46 patients with SARS-CoV-2 infection/COVID-19 were identified. The main pattern of viral transmission was intra-family. Eleven children were totally asymptomatic. If symptoms appeared, the disease had a mild course. A single case of COVID-19-related respiratory insufficiency was registered. Among children who underwent serological evaluation, 84% had seroconversion. No significant differences in antibody development were found according to the age and the burden of the disease. Children tested farther from the primary infection had lower antibody index titre values than the others. In conclusion, COVID-19 has a good prognosis in paediatric age. Children are able to develop a valid immune response, although their index titres seem to decrease a long time after the disease.
