ABSTRACT

Sense of belonging, perceived stress and wellbeing are reported factors that influence students' university experience and learning. The COVID-19 pandemic and shift to online emergency remote teaching were likely to exacerbate these affective dimensions of student experience. This article employed a quantitative survey research design to determine how students' sense of belonging, perceived stress and wellbeing were influenced during the pandemic. An online questionnaire was administered to 537 South African students at one residential university. Data analysis was performed using multiple regression analysis. The results indicated that platform pedagogy was a significant predictor of belonging, perceived stress, and wellbeing, while lecturers' pedagogical competence was not. Lived learning experience of online learning was a significant predictor of perceived stress, and communication was a significant predictor of belonging. The importance of the learning environment in student belonging and wellbeing is key to student success and this study provides insights for developing targeted interventions.

ABSTRACT

Objective The peripheral lymphocyte compartment of patients with primary Sjogren's syndrome (pSS) differs strongly from healthy individuals. Whether this altered lymphocyte composition also changes abnormally during immune reactions, especially by novel CoV- 2-vaccines, is unknown. Methods Peripheral blood mononuclear cells (PBMC) from 26 pSS patients and 6 healthy controls were compared before Coronavirus-2 (CoV-2) vaccination (Pfizer/BNT162b2, Moderna/mRNA-1273, AstraZeneca/AZD122 ChAdOx1 nCoV-19) and 7 days after secondary vaccination. Spike 1 (S1)-receptor binding domain (RBD)-specific IgG antibodies were measured in serum samples. Among PBMCs, B and T cell subpopulations were phenotypically analysed and RBD-specific B and plasma cells were evaluated. Results Immunisation induced CoV-2 specific serum antibodies in all pSS patients and healthy participants. When analysing pSS patients and controls together, frequencies of circulating IgG+ RBD-specific antibody-secreting cells (ASC) and anti-RBD serum titres correlated (r=0.42, p=0.022). Previously described alterations of peripheral B cells in pSS patients (e.g. reduced memory B cells, increased naive and transitional B cells and higher maturity of ASCs) remained stable during vaccination. The subset distribution of CD4+ and CD8+ T cells also stayed largely unchanged. However, frequencies of CD4+CXCR5-PD-1+ circulating peripheral helper T (cT(PH))-like cells increased in pSS patients comparing pre- and post-vaccination (p=0.020), while circulating CD4+CXCR5+PD-1+ follicular helper T (cT(FH))-like cells declined (p=0.024). Conclusion An immune reaction induced by vaccination with the novel CoV-2 vaccines yields adequate antibody production and vaccine specific lymphocytes in pSS patients and controls. Aberrant lymphocyte subset distribution in pSS patients persisted after vaccination and no major changes were induced despite small changes in cT(PH) and cT(FH) cells.

ABSTRACT

The sudden mass migration of teaching, learning and assessment to the digital terrain because of the COVID-19 pandemic resulted in the global proliferation of scholarship. This scholarship ranges from romantic notions of the opportunity to revivify curriculum and pedagogy in what was deemed an underutilised educational technology (online) resource space to scholarship contemptuous of this newfound romance. This has exposed the potential affordances of online teaching and its adjunctive exclusionary effects. Whilst the authors recognise the short-term benefits of adapting advanced technology for educational purposes, they provoke the question as to the obliterative potential of technology for the human (university academics in this instance) and the non-human/more-than-human. It is, however, without contention that the neoliberal university, driven by the economic viability and sustainability imperative, gives precedence to curriculum delivery and student support to secure degree completion targets even within academic timeframe (year) constraints. As such, it is likely to neglect the cogent matter of the affective as it relates to both academics, students and the non-human. In this conceptual article, Rosi Braidotti’s critical posthumanist perspective is drawn upon, offering both critical and affirmative propositions for moving forward in engagement with technologies in emerging educational online spaces. Firstly, critical perspectives are offered on some challenges of the neoliberal contouring and new regimes of accountability and surveillance that appear to have become more efficacious in the digital space. Secondly, it is acknowledged that humans live in a technologically mediated world and need to navigate this world in productive ways. Braidotti’s philosophy of affirmative ethics helps us to invigorate affordances of educational technology that are hopeful. This article’s contribution lies in alternative imaginings of educational technology, so that technology can be used in ways that advance pedagogical lives and social relations. © 2022. The Authors.

ABSTRACT

Objectives. The peripheral lymphocyte compartment of patients with primary Sjogren's syndrome (pSS) differs strongly from healthy individuals. Whether this altered lymphocyte composition also abnormally changes during immune reactions, especially in the context of novel mRNA-vaccines, is unknown. Methods. Peripheral blood samples from 26 pSS patients were compared to 6 healthy controls before Coronavirus-2 (CoV-2) vaccination (BNT162b2, ChAdOx1, mRNA-1273) and 7 days after secondary vaccination. Spike. 1 (S1)-receptor binding domain (RBD)-neutralizing IgG antibodies were measured in serum samples. Within peripheral blood mononuclear cells (PBMC), lymphocytes were characterized using spectral flow cytometry and B and T cell subpopulations were phenotypically analyzed. Results. Immunization induced CoV-2 specific serum antibodies in all pSS and healthy participants. When analyzing pSS and healthy individuals together, frequencies of circulating IgG+ RBD-binding antibody-secreting cells (ASC) and anti-CoV-2 serum titers correlated (r=0.42, p=0.022). Previously described alterations of peripheral B cells in pSS patients (like reduced memory B cells, increased naive and transitional B cells and higher maturity of ASCs) remained stable during vaccination. Also the subset distribution of CD4+ and CD8+ T cells mainly stayed unchanged. However, CD4+CXCR5-PD-1+ T cells phenotypically mimicking peripheral helper TPH cells increased in pSS patients comparing pre- and post-vaccination (p=0.020), while circulating CD4+CXCR5+PD-1+ follicular helper TFH cells declined (p=0.024). Conclusions. An immune reaction induced by vaccination with the novel mRNA technology yields adequate antibody production and vaccine specific lymphocytes in pSS patients and controls. However, no major changes within the typical composition of lymphocyte subpopulations of pSS patients were observed despite small changes in TPH and TFH subsets.

ABSTRACT

BACKGROUND: In patients with severe polycystic liver disease (PLD), there is a need for new treatments. Estrogens and possibly other female sex hormones stimulate growth in PLD. In some patients, liver volume decreases after menopause. Female sex hormones could therefore be a target for therapy. The AGAINST-PLD study will examine the efficacy of the GnRH agonist leuprorelin, which blocks the production of estrogen and other sex hormones, to reduce liver growth in PLD. METHODS: The AGAINST-PLD study is an investigator-driven, multicenter, randomized controlled trial. Institutional review board (IRB) approval was received at the University Medical Center of Groningen and will be collected in other sites before opening these sites. Thirty-six female, pre-menopausal patients, with a very large liver volume for age (upper 10% of the PLD population) and ongoing liver growth despite current treatment options will be randomized to direct start of leuprorelin or to 18 months standard of care and delayed start of leuprorelin. Leuprorelin is given as 3.75 mg subcutaneously (s.c.) monthly for the first 3 months followed by 3-monthly depots of 11.25 mg s.c. The trial duration is 36 months. MRI scans to measure liver volume will be performed at screening, 6 months, 18 months, 24 months and 36 months. In addition, blood will be drawn, DEXA-scans will be performed and questionnaires will be collected. This design enables comparison between patients on study treatment and standard of care (first 18 months) and within patients before and during treatment (whole trial). Main outcome is annualized liver growth rate compared between standard of care and study treatment. Secondary outcomes are PLD disease severity, change in liver growth within individuals and (serious) adverse events. The study is designed as a prospective open-label study with blinded endpoint assessment (PROBE). DISCUSSION: In this trial, we combined the expertise of hepatologist, nephrologists and gynecologists to study the effect of leuprorelin on liver growth in PLD. In this way, we hope to stop liver growth, reduce symptoms and reduce the need for liver transplantation in severe PLD.
