Mental health in distance learning: a taxonomy of barriers and enablers to student mental wellbeing

Student mental health is a critical issue in higher education. It is understood that higher education can act to trigger or exacerbate mental health difficulties, but research in this area has focused primarily on campus environments, identifying stressors such as halls of residence. Since distance learning students disclose mental health issues at a higher rate than campus students, and completion and progression gaps are on a par with the sector, it is critical that the barriers and enablers to mental wellbeing in distance learning are understood. This paper reports on a qualitative study that investigated barriers and enablers to mental wellbeing and study success that students experienced in distance learning. 15 distance learning students and 5 tutors were interviewed using narrative enquiry; students told their own stories and tutors told stories of students they had supported. Barriers and enablers were identified across different aspects of study, skills-development and the distance learning environment, and are presented in a taxonomy of barriers and enablers that suggest a range of implications for distance learning educators and policy developers

Dissolving the Dichotomies Between Online and Campus-Based Teaching: a Collective Response to The Manifesto for Teaching Online (Bayne et al. 2020)

This article is a collective response to the 2020 iteration of The Manifesto for Teaching Online. Originally published in 2011 as 20 simple but provocative statements, the aim was, and continues to be, to critically challenge the normalization of education as techno-corporate enterprise and the failure to properly account for digital methods in teaching in Higher Education. The 2020 Manifesto continues in the same critically provocative fashion, and, as the response collected here demonstrates, its publication could not be timelier. Though the Manifesto was written before the Covid-19 pandemic, many of the responses gathered here inevitably reflect on the experiences of moving to digital, distant, online teaching under unprecedented conditions. As these contributions reveal, the challenges were many and varied, ranging from the positive, breakthrough opportunities that digital learning offered to many students, including the disabled, to the problematic, such as poor digital networks and access, and simple digital poverty. Regardless of the nature of each response, taken together, what they show is that The Manifesto for Teaching Online offers welcome insights into and practical advice on how to teach online, and creatively confront the supremacy of face-to-face teaching

A novel variant in SMG9 causes intellectual disability, confirming a role for nonsense-mediated decay components in neurocognitive development

Biallelic loss-of-function variants in the SMG9 gene, encoding a regulatory subunit of the mRNA nonsense-mediated decay (NMD) machinery, are reported to cause heart and brain malformation syndrome. Here we report five patients from three unrelated families with intellectual disability (ID) and a novel pathogenic SMG9 c.551 T > C p.(Val184Ala) homozygous missense variant, identified using exome sequencing. Sanger sequencing confirmed recessive segregation in each family. SMG9 c.551T > C p.(Val184Ala) is most likely an autozygous variant identical by descent. Characteristic clinical findings in patients were mild to moderate ID, intention tremor, pyramidal signs, dyspraxia, and ocular manifestations. We used RNA sequencing of patients and age- and sex-matched healthy controls to assess the effect of the variant. RNA sequencing revealed that the SMG9 c.551T > C variant did not affect the splicing or expression level of SMG9 gene products, and allele-specific expression analysis did not provide evidence that the nonsense mRNA-induced NMD was affected. Differential gene expression analysis identified prevalent upregulation of genes in patients, including the genes SMOX, OSBP2, GPX3, and ZNF155. These findings suggest that normal SMG9 function may be involved in transcriptional regulation without affecting nonsense mRNA-induced NMD. In conclusion, we demonstrate that the SMG9 c.551T > C missense variant causes a neurodevelopmental disorder and impacts gene expression. NMD components have roles beyond aberrant mRNA degradation that are crucial for neurocognitive development

Several specific high-resolution computed tomography patterns correlate with survival in patients with idiopathic pulmonary fibrosis

Abstract Background: Evidence of honeycombing in high-resolution computed tomography (HRCT) is a recognized risk factor for shortened survival in patients with idiopathic pulmonary fibrosis (IPF), but few studies have evaluated the feasibility of exploiting other specific patterns for predicting survival. The aim of this study was to examine the extent of specific HRCT patterns in IPF and determine whether they correlate with clinical features, pulmonary function tests (PFT), and survival. Methods: Both the presence and extent of specific HRCT patterns, such as traction bronchiectasis, honeycombing, architectural distortion, reticulation, emphysema, and ground glass opacity, in 129 HRCT examinations were scored semi-quantitatively in three zones of each lung. HRCT examinations were also re-classified according to the 2011 and 2018 international statements. Correlations were calculated between the scores of specific HRCT patterns, clinical features, PFT, and patient survival. Results: The extent of traction bronchiectasis was found to be an independent risk factor of shortened survival (HR 1.227, P=0.001). Patients with a possible usual interstitial pneumonia (UIP) pattern had a better median survival than the patients with a definite UIP pattern (61 vs. 37 months, P=0.026). The extents of traction bronchiectasis, honeycombing, and architectural distortion displayed an inverse correlation with all PFT values at the time of diagnosis. There were few differences between the radiological classifications of the 2011 and 2018 international statements

Inflammatory myositis-associated interstitial lung disease can be distinguished from that associated with other connective tissue diseases

Abstract Background: Acute onset of interstitial lung disease (ILD) has been described in patients with idiopathic inflammatory myositis (IIM), but controlled studies about this issue are sparse. The aim of this study was to compare disease onset, demographics, and high-resolution computed tomography (HRCT) patterns in IIM-ILD and other connective tissue disease (CTD)-ILDs. Methods: Clinical and radiological data of 22 IIM-ILD and 132 other CTD-ILD patients was retrospectively gathered from hospital registries between January 2000 and November 2019. Data was re-assessed and compared using a multivariate analysis. Results: Compared to other CTD-ILDs, the patients with IIM-ILD were younger (59.7 vs. 68.0 years, P=0.023), more often non-smokers (71.4% vs. 45.7%, P=0.029) and displayed radiological nonspecific interstitial pneumonia/organizing pneumonia (NSIP/OP) overlap pattern more frequently (27.3% vs. 1.5%, P<0.001). The onset of ILD was acute with patients needing intensive care significantly more often in IIM-ILD than in other CTD-ILDs (22.7% vs. 2.3%, P<0.001). In most patients ILD was diagnosed before or simultaneously with IIM presentation unlike in other CTD-ILDs (90.9% vs. 47.7%, P<0.001). In multivariate analysis, NSIP/OP overlap pattern, acute onset disease treated in intensive care unit and ILD preceding or being diagnosed simultaneously with CTD were significantly associated with IIM-ILD. The multivariate model, supplemented with age, had excellent diagnostic performance identifying IIM-ILD [area under curve (AUC) 0.845]. Conclusions: Unlike other CTD-ILDs, IIM-ILD often develops acutely, simultaneously with the systemic disease. Therefore, clinicians should consider IIM-ILD as an option of differential diagnosis in patients with acute ILD and promptly test muscle enzymes as well as comprehensive autoantibody tests
