RESUMEN
COVID-19 disproportionately affects older people, with higher rates of infection and a higher risk of adverse outcomes. A brief review of literature was undertaken to inform development of a protocol describing the indications and process of prone positioning to aid the management of COVID-19 infection in non-mechanically ventilated, awake older adults. PubMed was searched up to 14th January 2021 to identify English language papers that described prone positioning procedures used in non-mechanically ventilated patients. Data were pooled to inform the development of a prone positioning protocol for use in hospital ward environments. The protocol was trialled and refined during routine clinical practice. Screening of 146 articles yielded five studies detailing a prone positioning protocol. Prone positioning is a potentially feasible and tolerated treatment adjunct for hypoxaemia in older adults with COVID-19. Future studies should further establish the efficacy, safety, and tolerability in respiratory illnesses in non-intensive care settings.

BACKGROUND/AIMS: Coronavirus Disease 2019 (COVID-19) has presented an unprecedented challenge for delivering clinical research. The use of technology-assisted data collection for clinical research is desirable for many practitioners, but the acceptability of use in the general population has not been assessed. The aim of the study was to assess attitudes towards using technology-assisted remote methods in the delivery of clinical research in the UK and to understand the barriers to taking part in research with respect to both remote assessments and traditional research methods across different age ranges. METHODS: The study was conducted as an online anonymous survey with a 4-part questionnaire, between August 2020 and December 2020. Participants living in the UK aged 18 years and above were eligible to take part. RESULTS: A total 351 completed the survey and are included in the data analysis. In all age groups, participants identified that use of online assignments, video calls and telephone calls would make them more likely to take part in clinical research. Overall, the largest barrier to taking part in research was time commitments and timing of the appointment. COVID-19 has had a small, positive influence on the confidence of using technology in the general population. CONCLUSIONS: The study found that there is a large interest in taking part in research using online, telephone and video call appointments, which could facilitate research delivery in light of ongoing COVID-19-related restrictions and also improve the accessibility and inclusivity of research.

BACKGROUND: Children with chronic kidney disease require specialist renal paediatric dietetic care, regardless of disease severity or geographical location; however, under-resourcing makes this challenging. Videoconsultation may offer a solution but research exploring its acceptability is limited. The present study explored parent/carer and child perspectives of videoconsultation as an alternative or supplement to existing regional dietetic care. METHODS: Children and families using a regional paediatric nephrology service were recruited through purposeful sampling techniques. Renal paediatric dietitians used existing hospital software to host videoconsultations with families. Perspectives were subsequently explored in telephone interviews with the children, their parents and separately with the renal dietitians. Data were transcribed verbatim and an inductive framework analysis conducted. RESULTS: Twelve families took part in the study, comprising 13 parents and five children (aged 9 months to 14 years). Two renal dietitians were also interviewed. Six themes emerged which were 'Logistics', 'Understanding Information', 'Family Engagement', 'Establishing Trust', 'Willingness to Change' and 'Preferences'. Satisfaction with the videoconsultations was high, with no data security fears and only minor privacy concerns. Parents reported that screen-sharing software enhanced their understanding, generating greater discussion and engagement compared to clinic and telephone contacts. Parents praised efficiencies and improved access to specialist advice, requesting that videoconsultations supplement care. Children preferred videoconsultations outright. CONCLUSIONS: Dietetic videoconsultations were acceptable to families and perceived to be a feasible, high-quality complement to regional specialist dietetic care. Enhanced understanding and engagement might improve self-care in adolescents. The acceptability and feasibility of videoconsultations could address inequitable regional service provision.

BACKGROUND: Familial hypercholesterolaemia (FH) is a genetic condition characterised by elevated levels of low-density lipoprotein cholesterol (LDL-C) and an increased risk of cardiovascular disease (CVD). Following dietary and physical activity guidelines could help minimise this risk but adherence is low. Interventions to target these behaviours are therefore required. A comprehensive understanding of the target behaviours and behaviour change theory should drive the process of intervention development to increase intervention effectiveness and scalability. This paper describes the application of a theoretical framework to the findings of a qualitative evidence synthesis (QES) to inform the content and delivery of an intervention to improve adherence to dietary and physical activity guidelines in individuals with FH. METHODS: The Behaviour Change Wheel (BCW) was used to guide intervention development. Factors influencing dietary and physical activity behaviours were identified from an earlier QES and mapped onto factors within the BCW. A comprehensive behavioural diagnosis of these factors was conducted through application of the theoretical domains framework (TDF). Using these data, the most appropriate intervention functions and behaviour change techniques (BCTs) for inclusion in the intervention were identified. Decision making was guided by evaluation criteria recommended by BCW guidance and feedback from individuals with FH. RESULTS: Factors influencing dietary and physical activity behaviours mapped onto twelve of the fourteen TDF domains, with seven intervention functions deemed suitable to target the domains' theoretical constructs. Twenty-six BCTs were identified as being appropriate for delivery within these functions and were included in the intervention. For instance, within the enablement intervention function, the BCT problem solving was incorporated by inclusion of a 'barriers and solutions' section. Guided by evaluation criteria and feedback from individuals with FH, the intervention will be delivered as an hour-long family-based appointment, followed up with four telephone calls. CONCLUSIONS: The novel application of the BCW and TDF to the results of a QES has enabled the development of a theory and evidence informed behaviour change intervention. This systematic approach facilitates evaluation of the intervention as part of an ongoing feasibility trial. The transparent approach taken can be used to guide intervention development by researchers in other fields.

OBJECTIVES: We aimed to examine associations between diet quality, falls risk, physical function, physical activity and body composition. DESIGN: Cross-sectional study. SETTING AND PARTICIPANTS: Data collected from 171 men and women, aged 60-88 years old, as part of the Falls Risk and Osteoporosis Longitudinal Study. MEASUREMENTS: Dietary Intake (Dietary Questionnaire for Epidemiological Studies Version 2 (DQES v2)), Falls Risk (FES-I, ABC, Berg Balance and Physiological Profile Assessment), Physical Function (SPPB), Physical Activity (PASE) and Body Composition (fat mass, lean mass, BMD, BMI, android/gynoid ratio) were ascertained. Diet quality was determined using two measures (Healthy Eating Index - HEI and Healthy Diet Indicator - HDI). One-way Analysis of Variance was used to compare mean scores between females and males and Pearson product-moment correlation coefficients were calculated to examine bivariate relationships. RESULTS: Although females and males were analysed separately, the HDI-total score showed more associations that the HEI in both genders. The HDI showed, in females weak negative associations with BMI (r =-.21, p=.04), gynoid fat (r = -.20, p=.01), total fat mass (r = -.20, p=.02), with a weak positive association between HDI and percentage lean mass (r =.20, p=.03). Males showed positive associations between HDI and age (r =.30 p=.02) physical function (SPPB)(r =.26, p=.04), and subjective falls-risk (ABC) (r =.26, p=.03). In addition, in males, a negative association was found between HDI and FES-I (r = -.25, p=.04). The only measure that was significantly associated with the HEI-total score was the android/gynoid ratio in males (r = -.29, p=.04). When controlling for age, females demonstrated weak positive associations between gynoid (r = .19 p = .02), android (r = .19, p = .02) and total fat mass (r = .20 p = .02) as well as weak negative correlation with lean mass (r = 1.19, p = .03). Age also impacts on the FES-I (r = .29 p <.01) and ABC (r = -.23 p <.01). CONCLUSIONS: The relationships between dietary quality and body composition, falls risk and physical function in older community dwelling, higher functioning adults appear to be gender specific. Better diet quality in females, is associated with lower BMI and fat mass, and higher lean mass, compared to males that are older and appear to have better physical function, are less likely to self-report falls risk, and have a better fat distribution i.e. a lower android/gynoid ratio have better diet quality. Furthermore, age is an important confounder and should be taken into consideration when assessing diet quality in older adults. In addition these gender and age differences may be clinically relevant and could aid in the delivery of targeted interventions.

PURPOSE: Physical activity is associated with a reduced risk of breast cancer development and recurrence. There are several hypothesised mechanisms for this including positive effects on metabolic and inflammatory biomarkers and favourable changes in anthropometric variables. This pilot study examined the effect of an 8-week aerobic exercise intervention on several of these outcomes, including body composition, the metabolic syndrome, C-reactive protein (CRP) and physical activity, in breast cancer survivors 2-6 months post-chemotherapy. METHODS: Assessments were completed at baseline, at 8-weeks and 3-months post-intervention. Measures taken following a 12-h fast included body composition (bioimpedance analysis), metabolic syndrome (waist circumference, blood pressure, high-density lipoprotein cholesterol, triglycerides and fasting glucose), insulin resistance (homeostatic model assessment), CRP and physical activity (accelerometry and questionnaire). Participants were randomized to either an 8-week moderate-intensity aerobic exercise group or a usual-care control group. Analysis was completed using repeated-measures analysis of variance (ANOVA) (p = 0.05). RESULTS: Twenty-six breast cancer survivors participated (mean (standard deviation) age 48.1 (8.8) years, exercise group; n = 16, control group; n = 10). At baseline, 13 participants were overweight, 6 were obese and 19 centrally obese. Intention-to-treat analysis revealed no significant differences between the exercise and control groups in any of the outcomes measures; however, analysis of those who adhered to >90 % of the supervised exercise class showed a significant decrease in waist circumference (p = 0.05) and a significant increase in subjectively reported "total weekly" (p = 0.005) activity. CONCLUSION: While this 8-week aerobic exercise pilot intervention did not elicit significant improvements in biomarkers of breast cancer risk, there was some suggestion of improvements in waist circumference and subjectively measured physical activity in participants with >90 % adherence to the programme. A trial of longer duration and greater subject numbers is warranted.

Poor nutritional status, which includesboth under- a nd over-nutrition, i s associated w it h poor health outcomes. T his cross-sectional study assessed the nutritional status of older patients admitted to an acute geriatric ward of a Dublin hospital. Anthropometric and clinical measurements were made. Thirty patients, mean (sd) age 79 (7) y and body mass index 26.6 (4.7) kg/m2, participated. More patients were overweight (n = 12) or obese (n = 9) than underweight (n= 1) or healthy weight (n = 8) which indicates that this age-group may be part of the Irish obesity epidemic.

BACKGROUND: Phosphatidylethanolamine (PE) is a phospholipid which is biosynthesized into long chain N-acylethanolamines (NAEs) including oleoylethanolamide (OEA), a known inhibitor of food intake. The aim of this study was to investigate whether PE-containing lipids can also inhibit intake. This was a 4 treatment intervention where 18 male participants were given a high-fat test breakfast (2.5 MJ, 53 en% fat) containing (i) high-phospholipid, high-PE lipid (ii) high-phospholipid, medium-PE lipid (iii) no-phospholipid, no-PE control lipid or (iv) water control, in a randomised cross-over. Visual analogue scales (VAS) were used to assess post-ingestive hunger and satiety, and energy intake (EI) was measured at an ad libitum lunch meal after 3.5 hours. RESULTS: When compared with the water control, the 3 lipid treatments resulted in lower levels of hunger and thoughts of food, greater fullness and satisfaction (all, treatment*time interaction, P<0.001), and a lower EI (P<0.05). However, there was no difference in any of the VAS measures when the 2 PE lipid treatments were compared with no-PE control lipid, nor when medium-PE was compared with high-PE. Unexpectedly participants ate significantly more energy at the lunch meal when the 2 PE lipid treatments (medium-PE:5406 kJ, 334 sem; high-PE:5288 kJ, 244 sem) were compared with the no-PE control lipid (5072 kJ, 262 sem, P<0.05), although there was no dose effect between the medium- and high-PE treatments. CONCLUSION: Despite the close relationship of PE with OEA, there was no evidence from this acute study that dietary phospholipids containing PE can favourably modify eating behaviour.
