Published: April 2021

Purpose: Dedicator of cytokinesis 8 (DOCK8) was reported to have a vital link to immunoregulation. However, the mechanisms by which it drives immune infiltration in cancer remain uncertain. We tried to assess the role of DOCK8 in patients with cancer, especially human papillomavirus (HPV)-positive head and neck squamous cell carcinoma (HNSCC). Methods: Data on the expression and survival of DOCK8 in patients with various cancers were analyzed using the Oncomine and TIMER databases. The TIMER database assessed the relationship of DOCK8 with immune infiltration levels and various markers of multiple immune cells. Gene set enrichment analysis revealed tumor-associated biological processes related to DOCK8. ENCODE database was used to explore relevant transcription factors of DOCK8, and a PPI network was constructed using GENEMINIA. The expression and survival role of DOCK8 was confirmed in patients from independent GEO datasets. Results: We determined that DOCK8 expression was upregulated or downregulated in various cancers unlike in healthy tissues. A high expression of DOCK8 was significantly correlated with a favorable prognosis in HPV-positive HNSCC and lung adenocarcinoma (LUAD). Furthermore, multivariate Cox regression analysis revealed that DOCK8 was an independent prognostic factor of HPV-positive HNSCC. Additionally, elevated DOCK8 expression was positively correlated with multiple immune cell infiltration levels and immune marker expression associated with particular immune cell subsets. Also, 14 pathways involved in immune activities and carcinogenesis, 22 potential TFs, and co-expression proteins of DOCK8 indicated DOCK8 to be related to tumor-associated biological processes. Ultimately, we verified that DOCK8 is upregulated and confers a favorable overall survival and progression-free survival status in patients with HPV-positive HNSCC. Conclusion: These results elucidate that high expression of DOCK8 indicates a favorable prognosis in patients with HPV-positive HNSCC as well as increased microenvironmental immune infiltration levels. It would provide new insights into the prognosis predicting and clinical regimen decision making in patients with HPV-positive HNSCC.

Authors: Campbell Quinn , Bodkin-Allen Sally , Swain Nicola 
Published: April 2021

The aim of this narrative review was to establish a link between psychological and physical wellbeing in people with and without chronic health conditions who participated in group singing. Four databases were searched (PubMed, WoS, MEDLINE, and Scopus) using a systematic search method. Articles were screened, yielding 19 suitable articles. In most studies that were included group singing led to an increase in both psychological and physiological wellbeing. The major impacts were on affect and depression and anxiety. Group singing positively affects both physical and psychological wellbeing in people with and without chronic health conditions. No direction of causality could be established.

Autism spectrum condition is associated with co-occurring physical health conditions and premature mortality. Autistic people experience multiple barriers to accessing healthcare. This study investigated autistic people’s experiences of healthcare and professionals’ experiences of providing healthcare to autistic people. Focus groups with 11 autistic people and one supporter, and 15 one-to-one interviews with healthcare professionals were completed. Nine themes emerged from the autistic participants’ data and eight themes emerged from the health professionals’ data. Three themes were identified by both groups: healthcare contacts (for improving the patient–provider relationship), making reasonable adjustments to healthcare (e.g. providing alternative places to wait for an appointment) and autism diagnosis. Autistic participants discussed the role of cognitive factors in the success of healthcare visits (such as rehearsing an anticipated conversation with the clinician the night before an appointment) and clinicians described system-level constraints that may affect healthcare delivery (such as time limits on appointments). This study identified inexpensive changes that health professionals and managers can make to improve healthcare access for autistic people. Lay abstract Research has shown that on average, autistic people are more likely to die earlier than non-autistic people, and barriers can stop autistic people accessing healthcare. We carried out a study where we interviewed healthcare professionals (including doctors and nurses), and held discussion groups of autistic people. Our results highlighted several key points: seeing the same professional is important for autistic people and clinicians; both clinicians and autistic people think making adjustments to healthcare is important (and often possible); autistic people process information in a different way and so may need extra support in appointments; and that clinicians are often constrained by time pressures or targets.

Published: April 2021

This pilot study aimed to explore the suitability of a preventative intervention for internalising problems in young children with chronic physical health conditions. The pilot study focused on a subsample of 27 children with chronic physical health conditions within a population-level randomised controlled trial of the Cool Little Kids parenting programme. The Cool Little Kids parenting programme aims to prevent the development of internalising problems in inhibited (shy/anxious) preschool children by educating parents to reduce young children’s avoidant coping styles and manage their anxiety/distress. The wider trial recruited 545 temperamentally inhibited preschool children. Measures included child health/development concerns and internalising symptoms at baseline, feedback on Cool Little Kids post-intervention and child internalising problems at one- and two-year longitudinal follow-up. At baseline, inhibited children with and without chronic physical health conditions had levels of internalising symptoms above the normative mean. At post-intervention, parents of children with chronic physical health conditions gave feedback that Cool Little Kids was helpful for managing their child’s emotional distress. At follow-up, significantly fewer intervention than control children with chronic physical health conditions had specific phobia after 1 year (25% vs 70%) and specific fear symptoms after 2 years (mean 9.57 vs 16.89). As the pilot findings are promising, a further trial of Cool Little Kids in a physical health treatment service with a larger sample of children with chronic physical illness diagnoses would be worthwhile.

Published: April 2021

Asthma symptoms impact children’s sleep quality. However, it is unclear how families’ daily management of their child’s asthma is associated with sleep quality. We examine associations between family asthma management components and sleep duration and quality for urban children (ages 7–9 years). Additionally, we examine these associations by racial/ethnic group. Data were collected as part of a longitudinal study that examined the co-occurrence of asthma, allergic rhinitis, sleep quality, and academic functioning for urban children diagnosed with persistent asthma ( N = 196). A semi-structured interview assessed family asthma management practices. Sleep quality data were collected via actigraphy. Our visual depiction of sleep outcomes show that those with higher family asthma management ratings present with longer sleep duration and better sleep quality. Among specific family asthma management components, we found a significant association between children’s adherence to asthma medications and number of nighttime awakenings. For non-Latino Black (NLB) children, we found a significant association between environmental control and sleep duration. For urban children with asthma, clinical strategies to enhance overall family asthma management have the potential to support improved sleep quality. Additionally, for NLB children, asthma management interventions that provide environmental control practices may increase sleep duration.

Carers may not always express child mental health concerns to health professionals. Therefore, identifying factors delaying help-seeking is important. The aim of this study was to examine the relationship between carer affect and help-seeking. In a secondary analysis of data collected from school-aged children ( N = 1,857, mean age = 9.85 years, 51% female), we used logistic regression to examine the associations between carer worry, help-seeking and child mental health. Regarding worry, higher levels of emotional problems (OR = 1.42, 95% CI = 1.33–1.52), conduct problems (OR = 1.24, 95% CI = 1.12, 1.36), peer problems (OR = 1.17, 95% CI = 1.05–1.27) or functional impairment (OR = 1.37, 95% CI = 1.2–.56) were associated with higher levels of carer worry. Regarding help-seeking, higher levels of functional impairment were associated with higher levels of help-seeking (OR = 1.51, 95% CI = 1.09–2.11). After controlling for mental health problems, carers who reported being worried about their child’s mental health were less likely than other carers to seek help (OR = 0.13, 95% CI = 0.05–0.35). Knowledge of these factors may inform early interventions. Alongside implications for future research and practice, limitations of the study are discussed.
Tensions in support for family caregivers of people with dementia in Singapore: A qualitative study
Authors: Basnyat Iccha , Chang Leanne 
Published: April 2021

Background Family members as informal caregivers are considered the first line of support for people with dementia across the world. In Singapore, caregiving expectations revolve around the cultural expectations of providing care in the home environment. However, studies in Singapore have identified a lack of family support for primary caregivers. Family support has been discussed in the literature as the provision of care for people with dementia, and rarely as a resource for family caregivers. Method To understand family support among primary caregivers in Singapore, 24 semi-structured interviews were conducted. Thematic analysis found four themes: excuses for lack of physical support for the caregiver, tensions between cultural expectations of caregiving and the provision of support, unmet emotional support, and lack of awareness of dementia and caregiving needs. Findings Caregivers rationalized and forgave the absence of physical support but were frustrated when the lack of support impacted people with dementia. This was seen as a lack of fulfilling cultural obligations of caring for elderly parents. The caregivers also felt frustrated with the lack of emotional support provided to them, but these were unspoken between the caregiver and the family members. Insufficient and unhelpful support giving was exacerbated with the perception of family members’ limited understanding of the demands of caregiving. Conclusion The findings offer four practical suggestions to address unmet support needs. First, public education is needed to enhance general knowledge about the symptoms and progression of dementia. Second, help is needed to address miscommunication about support within the family. Third, the development of guidebooks is needed to help family caregivers communicate with family members about their various support needs. Fourth, the relationship between cultural expectation and caregiving must be understood within the context of modernity and urbanism.

Published: April 2021

Background: Maternal hyperglycemia influences childhood metabolic syndrome, including obesity and hyperglycemia. We tested the hypothesis that the maternal hyperglycemia influences growth factors in the fetal and pre-adolescent offspring. Methods: Hyperglycemia was induced in pregnant rats on embryonic day (E)16 using streptozocin followed by implantation with insulin or placebo pellets at embryonic day 18 (E18). Fetuses at E20 and pre-adolescent pups at postnatal day 14 (P14) were studied: (1) normal untreated controls (CTL) at E20; (2) hyperglycemic placebo-treated (HPT) at E20; (3) hyperglycemic insulin-treated (HIT) at E20; (4) CTL at P14; and (5) HIT at P14. Fetal and pre-adolescent growth factors were determined. Results: Biomarkers of hypoxia were elevated in the HPT group at E20. This group did not survive to term. Maternal insulin improved fetal survival despite lower fetal body weight at E20, however, at normal birth (postnatal day 0 (P0)) and at P14, body weights and blood glucose were higher than CTL. These high levels correlated with aberrant growth factors. Maternal hyperglycemia influenced glucose-6-phosphate dehydrogenase, glucagon, insulin, interleukin-10, and leptin genes. Conclusions: The impact of maternal hyperglycemia on pre-adolescent glucose and body weight was not a consequence of maternal overnutrition. This suggests an independent link which may affect offspring metabolic health in later life.

Published: April 2021

Background: Dysregulation of RNA binding proteins (RBPs) has been identified in multiple malignant tumors correlated with tumor progression and occurrence. However, the function of RBPs is not well understood in hepatocellular carcinoma (HCC). Methods: The RNA sequence data of HCC was extracted out of the Cancer Genome Atlas (TCGA) database and different RBPs were calculated between regular and cancerous tissue. The study explored the expression and predictive value of the RBPs systemically with a series of bioinformatic analyzes. Results: A total of 330 RBPs, including 208 up-regulated and 122 down-regulated RBPs, were classified differently. Four RBPs (MRPL54, EZH2, PPARGC1A, EIF2AK4) were defined as the forecast related hub gene and used to construct a model for prediction. Further study showed that the high-risk subgroup is poor survived (OS) compared to the model-based low-risk subgroup. The area of the prognostic model under the time-dependent receiver operator characteristic (ROC) curve is 0.814 in TCGA training group and 0.729 in validation group, indicating a strong prognostic model. We also created a predictive nomogram and a web-based calculator ( https://dxyjiang.shinyapps.io/RBPpredict/ ) based on the 4 RBPs and internal validation in the TCGA cohort, which displayed a beneficial predictive ability for HCC. Conclusions: Our results provide new insights into HCC pathogenesis. The 4-RBP gene signature showed a reliable HCC prediction ability with possible applications in therapeutic decision making and personalized therapy.

Published: April 2021

Purpose: To evaluate the dosimetric accuracy of the default couch model of the QFix kVueTM Calypso couch top in the treatment planning system. Methods: With the gantry 180°, field size 20 × 20 cm, 6 MV, we measured the depth dose, off-axis dose, and dose plane of different depths in the phantom with the couch rails in and out, respectively. Isocenter doses at different angles were also obtained. The results were compared to the doses calculated using the default couch top model and the real scanned couch top model. Then we revised the default model according to the measured results. Results: With “Rails In,” the depth dose, off-axis dose, and dose plane of the default couch top model had a big difference with the dose of the real scanned couch top model and the measured result. The dose of the real scanned couch top model was much closer to the measured result, but in the region of the rail edge, the difference was still significant. With “Rails Out,” there was a minor difference between the measured result, the dose of the default couch top model and the real scanned couch top model. The difference between the measurement and the default couch top model became very small after being revised. Conclusions: It is better to avoid the beam angle passing through the couch rails in treatment plans, or you should revise the parameter of the QFix kVueTM Calypso couch top model based on the measured results, and verify the treatment plan before clinical practice.

Authors: Healy David , Flynn Aisling , Conlan Owen , McSharry Jenny , Walsh Jane 
Published: April 2021

Background: In the current digital age, new opportunities arise to support healthy ageing in older adults as frailty and immobility become more prominent. Immersive virtual reality, which can be defined as a fully computer-generated environment that is displayed through a headmounted display, is one of these technologies. Recently, there has been an increase in the number of qualitative studies exploring the potential for immersive virtual reality in assisting older adults—providing opportunities in health promotion and tackling social isolation and loneliness. With this in mind, the current review aims to explore the following research questions: (1) What are older adults’ experiences and perceptions of immersive virtual reality? (2) What are the specific barriers and facilitators to older adults’ use of immersive virtual reality? (3) Do older adults find immersive virtual reality acceptable? The objective of the current study is to systematically review and synthesize qualitative data exploring older adults’ experiences and perceptions of immersive virtual reality. Methods: A systematic review and thematic synthesis will be conducted. Two reviewers will complete title and abstract screening, full-text screening and, data extraction and quality appraisal. A thematic synthesis will be conducted by the lead author, after which the research team and other key stakeholders will discuss the findings and make any necessary changes. Thematic synthesis is derived from the qualitative method, thematic analysis. It involves three key steps: initial coding and grouping of these codes, the formation of descriptive themes from these codes and finally, going beyond the data to form novel insights and theories known as analytical themes. The following protocol has been written following the Preferred Reporting Items for Systematic review and Meta-Analysis Protocols (PRISMA-P) guidelines.

Published: April 2021

Background Currently, no consensus exists on the appropriate control specimen site to utilize in studies evaluating for biomarkers in chronic rhinosinusitis (CRS). Studies thus far have utilized tissue from various anatomic sites despite regional heterogeneity. Objective We set out to quantify the differences in biomarker levels present in inferior turbinate versus sphenoid sinus mucosa in paired healthy control patients. We hypothesize that statistically significant differences in cytokine/chemokine expression exist between these two distinct sites. Methods A 38-plex commercially available cytokine/chemokine Luminex Assay was performed on 54 specimens encompassing paired inferior turbinate and sphenoid sinus mucosa samples from 27 patients undergoing endoscopic anterior skull base surgery. Patients with a history of CRS were excluded. Paired sample t-tests and Fisher’s exact tests were performed. Results Twenty-seven patients were included in the study, including 10 male and 17 female patients with an average age of 48 years. The following 8 biomarkers had statistically significant concentration differences between inferior turbinate mucosa and sphenoid mucosa sites: Flt-3L, Fractalkine, IL-12p40, IL-1Ra, IP-10, MCP-1, MIP-1β, and VEGF, with all P-values <0.01. Conclusion No consensus exists regarding the optimal choice of control specimen for CRS research. We present statistically significant quantitative differences in biomarker levels between paired inferior turbinate and sphenoid mucosa samples. This confirms the presence of heterogeneity between different subsites of sinonasal mucosa and highlights the need for standardization in future CRS research.

Published: April 2021

Background In FEVAR, visceral stents provide continuity and maintain perfusion between the main body of the stent and the respective visceral artery. The aim of this study was to characterise the incidence and mode of visceral stent failure (type Ic endoleak, type IIIa endoleak, stenosis/kink, fracture, crush and occlusion) after FEVAR in a large cohort of patients at a high-volume centre. Methods A retrospective review of visceral stents placed during FEVAR over 15 years (February 2003-December 2018) was performed. Kaplan-Meier analyses of freedom from visceral stent-related complications were performed. The outcomes between graft configurations of varying complexity were compared, as were the outcomes of different stent types and different visceral vessels. Results Visceral stent complications occurred in 47/236 patients (19.9%) and 54/653 stents (8.3%). Median follow up was 3.7 years (IQR 1.7–5.3 years). There was no difference in visceral stent complication rate between renal, SMA and coeliac arteries. Visceral stent complications were more frequent in more complex grafts compared to less complex grafts. Visceral stent complications were more frequent in uncovered stents compared to covered stents. Visceral stent-related endoleaks (type Ic and type IIIa) occurred exclusively around renal artery stents. The most common modes of failure with SMA stents were kinking and fracture, whereas with coeliac artery stents it was external crush. Conclusion Visceral stent complications after FEVAR are common and merit continued and close long-term surveillance. The mode of visceral stent failure varies across the vessels in which the stents are located.
