Identification of nutritional risk in the acute care setting: progress towards a practice and evidence informed systems level approach.

BACKGROUND: To improve nutritional assessment and care pathways in the acute care setting, it is important to understand the indicators that may predict nutritional risk. Informed by a review of systematic reviews, this project engaged stakeholders to prioritise and reach consensus on a list of evidence based and clinically contextualised indicators for identifying malnutrition risk in the acute care setting. METHODS: A modified Delphi approach was employed which consisted of four rounds of consultation with 54 stakeholders and 10 experts to reach consensus and refine a list of 57 risk indicators identified from a review of systematic reviews. Weighted mean and variance scores for each indicator were evaluated. Consistency was tested with intra class correlation coefficient. Cronbach's alpha was used to determine the reliability of the indicators. The final list of indicators was subject to Cronbach's alpha and exploratory principal component analysis. RESULTS: Fifteen indicators were considered to be the most important in identifying nutritional risk. These included difficulty self-feeding, polypharmacy, surgery and impaired gastro-intestinal function. There was 82% agreement for the final 15 indicators that they collectively would predict malnutrition risk in hospital inpatients. CONCLUSION: The 15 indicators identified are supported by evidence and are clinically informed. This represents an opportunity for translation into a novel and automated systems level approach for identifying malnutrition risk in the acute care setting.

Does a neutropenic diet reduce adverse outcomes in patients undergoing chemotherapy?

OBJECTIVE: This study aimed to compare clinical outcomes of chemotherapy patients who received either a neutropenic diet (ND) or liberalised diet (LD) and to investigate associations between ND and infectious outcomes. METHODS: A retrospective case note audit of patients admitted to Flinders Medical Centre from 2013 to 2017 was conducted. Patients were eligible if they were aged 18 years and above, received chemotherapy and were neutropenic during admission. Demographic and clinical data were collected from medical records. Primary outcomes were occurrence of infections and fever. Secondary outcomes include hospital length of stay and infection-related mortality. RESULTS: Seventy-nine patients received ND while 75 patients received LD. The ND group had more patients with acute myeloid leukaemia (p < .001) and receiving high-toxicity chemotherapy (p = .005). Incidence of febrile neutropenia (p = .016), bacteraemia (p = .044) and number of febrile days (p = .033) was higher in the ND group. ND was not independently associated with occurrence of febrile neutropenia or infections. Subsample analysis of 20 pairs of patients matched on age, sex and cancer diagnosis found no significant differences in clinical outcomes between groups. CONCLUSION: ND was not associated with the prevention of adverse outcomes in chemotherapy patients.

Nutrition-related outcomes and dietary intake in non-mechanically ventilated critically ill adult patients: A pilot observational descriptive study.

BACKGROUND: Critically ill patients who do not receive invasive mechanical ventilation (IMV) are a growing population, experiencing complex interventions that may impair dietary intake and nutrition-related outcomes. OBJECTIVES: The objectives of this study were to quantify intake and nutrition-related outcomes of non-IMV critically ill patients and to establish feasibility of methods to measure nutrition-related outcomes in this population. METHODS: Non-IMV adult patients expected to remain in the intensive care unit (ICU) for ≥24 h were eligible. Nutrition-related outcomes were assessed at baseline by subjective global assessment (SGA); on alternate study days by mid-upper arm circumference (MUAC), calf circumference (CC), and ultrasound of quadriceps muscle layer thickness (QMLT); and daily by body weight and bioelectrical impedance analysis (BIA). Data were censored at day 5 or ICU discharge. Dietary intake from all sources, including oral intake via investigator-led weighed food records, was quantified on days 1-3. Feasibility was defined as data completion rate ≥70%. Data are expressed as mean (standard deviation) or median [interquartile range (IQR)]. RESULTS: Twenty-three patients consented (50% male; 53 [42-64] y; ICU stay: 2.8 [1.9-4.0] d). Nutrition-related outcomes at baseline and ICU discharge were as follows: MUAC: 33.2 (8.6) cm (n = 18) and 29.3 (5.4) cm (n = 6); CC: 39.5 (7.4) cm (n = 16) and 37.5 (6.2) cm (n = 6); body weight: 95.3 (34.8) kg (n = 19) and 95.6 (41.0) kg (n = 10); and QMLT: 2.6 (0.8) cm (n = 15) and 2.5 (0.3) cm (n = 5), respectively. Oral intake provided 3155 [1942-5580] kJ and 32 [20-53] g protein, with poor appetite identified as a major barrier. MUAC, CC, QMLT, and SGA were feasible, while BIA and body weight were not. CONCLUSIONS: Oral intake in critically ill patients not requiring IMV is below estimated requirements, largely because of poor appetite. The small sample and short study duration were not sufficient to quantify changes in nutrition-related outcomes. MUAC, CC, QMLT, and SGA are feasible methods to assess nutrition-related outcomes at a single time point in this population.

Eating occasions and the contribution of foods to sodium and potassium intakes in adults.

OBJECTIVE: To examine dietary Na and K intake at eating occasions in Australian adults and identify the contribution of major food sources to Na and K at different eating occasions. DESIGN: Secondary analysis of 24 h recall diet data from the Australian Health Survey (2011-2013). SETTING: Nationally representative survey in Australia. SUBJECTS: Male and female Australians aged 18-84 years (n 7818). RESULTS: Dinner contributed the greatest proportion to total daily Na intake (33 %) and K intake (35 %). Na density was highest at lunch (380 mg/MJ) and K density highest at between-meal time eating occasions (401 mg/MJ). Between-meal time eating occasions provided 20 % of daily Na intake and 26 % of daily K intake. The major food group sources of Na were different at meal times (breads and mixed dishes) compared with between-meal times (cakes, muffins, scones, cake-type desserts). The top food group sources of K at meal times were potatoes and unprocessed meat products and dishes. CONCLUSIONS: Foods which contributed to Na and K intake differed according to eating occasion. Major food sources of Na were bread and processed foods. Major food sources of K were potatoes and meat products and dishes. Public health messages that emphasise meal-based advice and diet patterns high in vegetables, fruits and unprocessed foods may also aid reduction in dietary Na intake and increase in dietary K intake.

The association between body fat and musculoskeletal pain: a systematic review and meta-analysis.

BACKGROUND: Obesity and musculoskeletal pain are strongly related, but there is emerging evidence that body fat, not body weight, may be a better indicator of risk. There is, therefore, a need to determine if body fat is associated with musculoskeletal pain as it may improve management strategies. The aim of this systematic review was to investigate the association between body fat and musculoskeletal pain. METHODS: Seven electronic databases were searched from inception to 8th January 2018. Cross-sectional and longitudinal studies investigating the association between measures of body fat and musculoskeletal pain were included. All included articles were assessed for methodological rigour using the Epidemiology Appraisal Instrument. Standardised mean differences (SMDs) and effect estimates were pooled for meta-analysis. RESULTS: A total of 10,221 citations were identified through the database searching, which after abstract and full-text review, yielded 28 unique articles. Fourteen studies were included in the meta-analyses, which found significant cross-sectional associations between total body fat mass and widespread pain (SMD 0.49, 95% CI 0.37-0.61, p < 0.001). Individuals with low-back pain and knee pain had a higher body fat percentage than asymptomatic controls (SMD 0.34, 95% CI 0.17-0.52, p < 0.001 and SMD 0.18, 95% CI 0.05-0.32, p = 0.009, respectively). Fat mass index was significantly, albeit weakly, associated with foot pain (SMD 0.05, 95% CI 0.03-0.06, p < 0.001). Longitudinal studies (n = 8) were unsuitable for meta-analysis, but were largely indicative of elevated body fat increasing the risk of incident and worsening joint pain. There was conflicting evidence for an association between body fat percentage and incident low-back pain (3 studies, follow-up 4-20 years). Increasing knee pain (1 study) and incident foot pain (2 studies) were positively associated with body fat percentage and fat mass index. The percentage of items in the EAI graded as 'yes' for each study ranged from 23 to 85%, indicating variable methodological quality of the included studies. CONCLUSIONS: This systematic review and meta-analysis identified positive cross-sectional associations between increased body fat and widespread and single-site joint pain in the low-back, knee and foot. Longitudinal studies suggest elevated body fat may infer increased risk of incident and worsening joint pain, although further high-quality studies are required.

Does the presence of cardiovascular disease risk factors or established disease influence the dietary intake of affected adults and their children residing in the same household? A secondary analysis of the Australian Health Survey (2011-2013).

BACKGROUND: Diet is an important contributor to risk of cardiovascular disease (CVD) and integral in management and delaying progression. Little is known however about whether increased CVD risk or established CVD has any influence on dietary intakes of Australian adults or children residing in the same household. This study aimed to determine whether the presence of CVD or CVD risk factors influences dietary intake of Australian adults and if the presence of an adult with increased CVD risk influences the dietary intake of a child living in the same household. METHODS: Data were sourced from the 2011-2013 Australian Health Survey for: (1) adults ≥18 years with risk factors or established CVD and (2) children 2-17 years residing in the same household as adults with CVD risk factors or established CVD. Selected nutrient intakes (total fat, saturated fat plus trans fat, alpha-linolenic acid, total long chain omega 3 fatty acids, fibre and sodium) collected by repeated 24 h recalls were compared to national dietary recommendations and to the intakes of all other adults and children surveyed. Standard errors of the estimates were calculated using the replicate weights method, and an alpha value of <0.05 considered statistically significant. RESULTS: Six thousand two hundred sixty five of 9435 adults surveyed were identified as having CVD risk factors or established disease and of these 1609 had a child in the same household that also contributed data in this survey. No differences were observed in adjusted mean dietary intakes between those without risk factors or established CVD and those with, except for total energy and sodium which were significantly lower in the adults with CVD risk factors and/or established disease. However sodium intakes across both groups were higher than recommended targets. There were no differences for selected nutrients between children residing with affected adults and other children surveyed. CONCLUSIONS: While intakes of Australian adults with CVD risk factors or established disease were favourable for sodium, compared to unaffected adults, there is still scope for improvement as many Australian adults, despite CVD risk, are unable to achieve targets for selected nutrients. Effective dietary behaviour change strategies and resources are urgently needed.

Foot pain severity is associated with the ratio of visceral to subcutaneous fat mass, fat-mass index and depression in women.

Body composition and poor mental health are risk factors for developing foot pain, but the role of different fat deposits and psychological features related to chronic pain are not well understood. The aim of this study was to investigate the association between body composition, psychological health and foot pain. Eighty-eight women participated in this study: 44 with chronic, disabling foot pain (mean age 55.3 SD 7.0 years, BMI 29.5 SD 6.7 kg/m2), and 44 age and BMI matched controls. Disabling foot pain was determined from the functional limitation domain of the Manchester Foot Pain and Disability Index. Body composition was measured using dual X-ray absorptiometry and psychological health (catastrophisation, central sensitisation and depression) was measured using three validated questionnaires. Between-group analyses found that foot pain was not significantly associated with body composition variables, but was significantly associated with all psychological health measures (P < 0.001-0.047). Within-group analyses found that the severity of foot pain was significantly correlated with body composition measures: fat mass (total, android, gynoid, and visceral), fat-mass ratios [visceral/subcutaneous (VAT/SAT), visceral/android], fat-mass index (FMI), and depression. In multivariable analysis, VAT/SAT (ß 1.27, 95% CI 0.28-2.27), FMI (ß 0.14, 95% CI 0.02-0.25) and depression (ß 0.06, 95% CI 0.00-0.12) were independently associated with foot pain severity. Psychological health, not body composition, was associated with prevalent foot pain. For women with foot pain, VAT/SAT, FMI and depression were associated with severity. Further work is needed to determine if a reduction in fat mass reduces the severity of foot pain.

Dietary intake of working women with children does not appear to be influenced by hours of employment: A secondary analysis of the Australian Health Survey (2011-2013).

UNLABELLED: Women with children often fulfil multiple roles of running a household, raising a family and working outside the home. Good nutrition during this time is important to optimise their performance and prevent lifestyle diseases. Women also act as nutritional gatekeepers for their family. The dual burden of paid employment and unpaid family work may be associated with time scarcity in mothers which can impact food preparation and therefore nutritional adequacy. The aim of this study was to examine the diet of women who lived with children by comparison of hours worked. METHODS: This was a secondary analysis of the Australian National Nutrition and Physical Activity Survey 2011-12. Subjects were women aged 18-65 years who resided with ≥1 child (<18 years). Women were grouped according to hours of employment: not working; working <25 h a week; and working ≥25 hours a week. Data from two 24-h dietary recalls were used to compare differences between groups in nutrient intake and proportion of energy from discretionary foods. Covariates included were age, education, smoker status, Socio-Economic Indexes for Areas (SEIFA), number of persons in household, week or weekend day of the survey and the sequence of recalls. RESULTS: Analyses included 1869 women. Dietary intakes varied minimally between groups with intakes of fibre, vitamin C, and calcium lowest in the group not working. Overall diet quality was poor with >30% of energy coming from discretionary foods in all groups. CONCLUSIONS: Usual hours of employment per week have a minimal effect on diet quality in women with children. It is likely that different factors specific to each group contribute to the poor dietary intakes and should be further investigated.

Evaluation of tools used to measure calcium and/or dairy consumption in adults.

OBJECTIVE: To identify and critique tools for the assessment of Ca and/or dairy intake in adults, in order to ascertain the most accurate and reliable tools available. DESIGN: A systematic review of the literature was conducted using defined inclusion and exclusion criteria. Articles reporting on originally developed tools or testing the reliability or validity of existing tools that measure Ca and/or dairy intake in adults were included. Author-defined criteria for reporting reliability and validity properties were applied. SETTING: Studies conducted in Western countries. SUBJECTS: Adults. RESULTS: Thirty papers, utilising thirty-six tools assessing intake of dairy, Ca or both, were identified. Reliability testing was conducted on only two dairy and five Ca tools, with results indicating that only one dairy and two Ca tools were reliable. Validity testing was conducted for all but four Ca-only tools. There was high reliance in validity testing on lower-order tests such as correlation and failure to differentiate between statistical and clinically meaningful differences. Results of the validity testing suggest one dairy and five Ca tools are valid. Thus one tool was considered both reliable and valid for the assessment of dairy intake and only two tools proved reliable and valid for the assessment of Ca intake. CONCLUSIONS: While several tools are reliable and valid, their application across adult populations is limited by the populations in which they were tested. These results indicate a need for tools that assess Ca and/or dairy intake in adults to be rigorously tested for reliability and validity.

Evaluation of tools used to measure calcium and/or dairy consumption in children and adolescents.

OBJECTIVE: To identify and critique tools that assess Ca and/or dairy intake in children to ascertain the most accurate and reliable tools available. DESIGN: A systematic review of the literature was conducted using defined inclusion and exclusion criteria. Articles were included on the basis that they reported on a tool measuring Ca and/or dairy intake in children in Western countries and reported on originally developed tools or tested the validity or reliability of existing tools. Defined criteria for reporting reliability and validity properties were applied. SETTING: Studies in Western countries. SUBJECTS: Children. RESULTS: Eighteen papers reporting on two tools that assessed dairy intake, ten that assessed Ca intake and five that assessed both dairy and Ca were identified. An examination of tool testing revealed high reliance on lower-order tests such as correlation and failure to differentiate between statistical and clinically meaningful significance. Only half of the tools were tested for reliability and results indicated that only one Ca tool and one dairy tool were reliable. Validation studies showed acceptable levels of agreement (<100 mg difference) and/or sensitivity (62-83 %) and specificity (55-77 %) in three Ca tools. With reference to the testing methodology and results, no tools were considered both valid and reliable for the assessment of dairy intake and only one tool proved valid and reliable for the assessment of Ca intake. CONCLUSIONS: These results clearly indicate the need for development and rigorous testing of tools to assess Ca and/or dairy intake in children and adolescents.

A world-first food service satisfaction questionnaire for use with family members of nursing home residents: expanding the toolkit of valid and reliable aged care food service satisfaction questionnaires.

OBJECTIVES: This study aimed to develop a valid and reliable food service satisfaction questionnaire for use by family members of residents in nursing homes. DESIGN: Questionnaire development and validation study conducted using COSMIN® benchmarks for excellence. SETTING: Nursing homes. PARTICIPANTS: Family members of residents in nursing homes. MEASUREMENTS: Content validity was established based on a review of the literature, qualitative interviews with family members (n = 9) and expert review (n = 10). Face validity was established in pilot testing with family members (n = 5). A 40-item questionnaire was developed for psychometric testing. Data from 414 family members was used to establish construct validity (Principal Components Analysis), with data from 101 of those family members used to evaluate reliability (internal consistency (Cronbach's alpha [α]) and temporal stability [weighted Kappa]). RESULTS: A two factor 24-item scale resulted, with excellent internal consistency (factor one: 11 items related to food and meals (α = 0.960); factor two: 13 items related to the mealtime experience (α = 0.907)). Temporal stability was moderate to near perfect (weighted Kappa: 0.461-0.875; p < 0.001). CONCLUSION: This world-first, valid and reliable, food service satisfaction questionnaire for use with family members of nursing home residents meets COSMIN® standards for excellence and complements the Flinders University resident and workforce food service satisfaction questionnaires also available for use in nursing homes.

Barriers and Enablers to a Hospital-to-Home, Combined Exercise and Nutrition, Self-Managed Program for Pre-Frail and Frail Hospitalised Older Adults.

INTRODUCTION: Self-managed exercise and nutrition interventions can alleviate pre-frailty and frailty but understanding of adherence to them is lacking. This study aimed to explore the experiences of, and barriers and enablers to, a hospital-to-home self-managed combined exercise and nutrition program for hospitalised older adults living with pre-frailty and frailty. METHODS: A hybrid approach to data- and theory-driven descriptive thematic analysis identified experiences, barriers, and enablers to participation in a 3-month, self-managed, exercise-nutrition, hospital-to-home frailty-support program. Pre-frail and frail older adult patients ≥ 65 years admitted to the acute medical unit at a South Australian tertiary hospital were recruited. Individual semi-structured interviews were audio-recorded, transcribed verbatim, and analysed descriptively, using the Theoretical Domains Framework. RESULTS: The nutrition component of the program found 11 common barriers and 18 common enablers. The exercise component included 14 barriers and 24 enablers. Intentions, Social influences, Environmental context/resource and Emotions served as primary barriers towards adherence to both components. Common enablers for both components included Knowledge, Social identity, Environmental context/resource, Social influences, and Emotions. CONCLUSIONS: This research revealed important factors affecting adherence to a self-managed exercise-nutrition program in pre-frail and frail older adults within the environment, resources, and emotion domains that should be considered when designing other intervention programs in this population group.

Pre-Frailty and Frailty in Hospitalized Older Adults: A Comparison Study in People with and without a History of Cancer in an Acute Medical Unit.

A prospective observational study was conducted in a cohort of older adults ≥65 years (n = 329), admitted to the acute medical unit (AMU) of a tertiary hospital, to describe and compare characteristics including frailty status and clinical outcomes. Multivariable models compared older adults with and without a history of cancer to determine characteristics associated with frailty and pre-frailty. An adjusted Poisson regression model was used to compare the length of hospital stay (LOS) between the two groups. About one-fifth (22%) of the cohort had a history of cancer. The most common cancer types were prostate (n = 20), breast (n = 13), lung (n = 8) and gastrointestinal (n = 8). There was no difference in the prevalence of pre-frailty/frailty among patients with or without a history of cancer (58% vs. 57%, p > 0.05). Pre-frailty/frailty was associated with polypharmacy (OR 8.26, 95% CI: 1.74 to 39.2) and malnutrition (OR 8.91, 95% CI: 2.15 to 36.9) in patients with a history of cancer. Adjusted analysis revealed that the risk of having a longer LOS was 24% higher in older adults with a history of cancer than those without (IRR 1.24, 95% CI 1.10 to 1.41, p < 0.001). Clinicians in the AMU should be aware that older adults with a history of cancer have a higher risk of a longer LOS compared to those without.

Measuring Food Service Satisfaction amongst Residents Living in Nursing Homes-A New and Valid Person-Centered Approach.

Resident satisfaction with food services contributes to health and wellbeing. Measuring resident satisfaction is important; however, the small number of existing food service satisfaction questionnaires (FSSQs) are outdated, lack rigorous psychometric testing and do not reflect the shift to person-centered care. This study aimed to develop a valid and reliable FSSQ. Content validity was established by conducting interviews with residents, a systematic literature review and consultation with an expert panel. Data from 387 residents were used to establish construct validity (Principal Components Analysis), internal consistency (Cronbach's alpha) and temporal stability (Gwet's AC). The result was a three factor, 25-item scale with good/excellent internal consistency: Factor One (13 items-good food/service, α = 0.896), Factor Two (seven items-resident choice/food availability α = 0.648) and Factor Three (five items-resident participation/staff assistance, α = 0.729). Temporal stability was good/very good (Gwet's AC 0.6242-0.9799 (p < 0.001). This is the first FSSQ available to nursing homes that meets the COSMIN® standards for excellence and incorporates person-centered care. The questionnaire is simple to use and interpret, providing food service managers with an accurate and reliable measure of resident satisfaction and assisting them in providing a meal and dining experience that supports the health and wellbeing of residents.

Individualized Hospital to Home, Exercise-Nutrition Self-Managed Intervention for Pre-Frail and Frail Hospitalized Older Adults: The INDEPENDENCE Randomized Controlled Pilot Trial.

Purpose: Pre-frailty and frailty in older adults are associated with poor health outcomes and increase health-care costs, and further worsening during hospitalization. This study aimed to examine the effect of an individualized hospital to home, exercise-nutrition self-managed intervention for pre-frail and frail hospitalized older adults. Patients and Methods: Older adults admitted to an acute medical unit of a tertiary hospital in South Australia who were pre-frail or frail were recruited from September 2020 to June 2021, randomized to either control or intervention group and followed up at 3 and 6 months. The outcome variables were program adherence, frailty status by the Edmonton Frail Scale (EFS) score, lower extremity physical function, handgrip strength, nutritional status, cognition, mood, health-related quality of life, risk of functional decline, unplanned readmissions. Results: Participants were 79.2 ±6.6 years old, 63% female, mostly frail (67%), with EFS of 8.6±1.9. Adherence to the inpatient and home visits/telehealth intervention were high (91±13% and 92±21%, respectively). Intention-to-treat analysis using linear regression models showed that participants in the intervention group had significantly greater reduction in EFS at 3 (-3.0; 95% CI: -4.8 to -3.0) and 6 months (-2.5; 95% CI: -3.8 to -1.0, P<0.001 for both) compared to the control group; particularly the functional performance component. There were also improvements in overall Short Physical Performance Battery score at 3 (4.0; 95% CI: 1.3 to 6.6) and 6 months (3.9; 95% CI: 1.0 to 6.9, P<0.05 for both), mini-mental state examination (2.6; 95% 0.3-4.8, P=0.029) at 3 months and handgrip strength (3.7; 95% CI: 0.2-7.1, P=0.039) and Geriatric Depression Scale, at 6 months (-2.2; 95% CI: -4.1 to -0.30, P=0.026) in the intervention group as compared to control. Conclusion: This study provided evidence of acceptability to a patient self-managed exercise-nutrition program that may benefit and alleviate pre-frailty and frailty in hospitalised older adults.

Nutrition and diabetes self-management in aged care: Exploring community-dwelling older adults' expectations.

OBJECTIVES: To explore the diabetes self-management expectations of older adults with diabetes, not yet accessing residential aged care services. Admission to residential aged care (RAC) can create many interruptions to usual food choices and diabetes self-management, and we know little about the concerns of the emerging ageing population. METHODS: This is a qualitative study employing focus groups and inductive thematic analysis involving 18 older adults with diabetes between the ages of 60 and 88, living in their own homes within an Australian city. Focus groups were recruited on a sequential basis and progressively analysed using an inductive process until data saturation was reached. Focus groups were digitally recorded and transcribed verbatim for thematic analysis. RESULTS: Three key themes were generated: autonomy, individualised dietary management and the food service system. Older adults speculated that they would want a collaborative approach to maintain their health in ageing and to self-manage their diabetes while feasible. Participants wanted autonomy over food choices, flexible meal timings and quality meals. There was a significant anxiety that aged care staff and existing food service systems in RAC could not support these preferences. CONCLUSIONS: Community-dwelling older adults with diabetes would highly value aged care services that facilitated autonomy, individualised nutrition support and flexibility, but feared this will not be feasible. The introduction of new diabetes and RAC guidelines may require an implementation plan to include the full food service system, from staff education to meal preparation, ordering and service.

Association Between Mobile Health App Engagement and Weight Loss and Glycemic Control in Adults With Type 2 Diabetes and Prediabetes (D'LITE Study): Prospective Cohort Study.

BACKGROUND: Mobile health apps are increasingly used as early intervention to support behavior change for diabetes prevention and control, with the overarching goal of lowering the overall disease burden. OBJECTIVE: This prospective cohort study conducted in Singapore aimed to investigate app engagement features and their association with weight loss and improved glycemic control among adults with diabetes and prediabetes from the intervention arm of the Diabetes Lifestyle Intervention using Technology Empowerment randomized controlled trial. METHODS: Diabetes and prediabetes participants (N=171) with a median age of 52 years, BMI of 29.3 kg/m2, and glycated hemoglobin (HbA1c) level of 6.5% and who were being assigned the Nutritionist Buddy Diabetes app were included. Body weight and HbA1c were measured at baseline, 3 months, and 6 months. A total of 476,300 data points on daily app engagement were tracked via the backend dashboard and developer's report. The app engagement data were analyzed by quartiles and weekly means expressed in days per week. Linear mixed model analysis was used to determine the associations between the app engagements with percentage weight and HbA1c change. RESULTS: The median overall app engagement rate was maintained above 90% at 6 months. Participants who were actively engaged in ≥5 app features were associated with the greatest overall weight reduction of 10.6% from baseline (mean difference -6, 95% CI -8.9 to -3.2; P<.001) at 6 months. Adhering to the carbohydrate limit of >5.9 days per week and choosing healthier food options for >4.3 days per week had the most impact, eliciting weight loss of 9.1% (mean difference -5.2, 95% CI -8.2 to -2.2; P=.001) and 8.8% (mean difference -4.2, 95% CI -7.1 to -1.3; P=.005), respectively. Among the participants with diabetes, those who had a complete meal log for >5.1 days per week or kept within their carbohydrate limit for >5.9 days per week each achieved greater HbA1c reductions of 1.2% (SD 1.3%; SD 1.5%), as compared with 0.2% (SD 1%; SD 0.6%). in the reference groups who used the features <1.1 or ≤2.5 days per week, respectively. CONCLUSIONS: Higher app engagement led to greater weight loss and HbA1c reduction among adults with overweight or obesity with type 2 diabetes or prediabetes.

Identification and Critical Appraisal of Food Service Satisfaction Questionnaires for Use in Nursing Homes: A Systematic Review.

BACKGROUND: Food service provision in nursing homes is a complex, adaptive system through which multiple stakeholders interface. Organizational stakeholders include staff involved in preparing and delivering meals. Consumer stakeholders are the end users including residents and family. Questionnaires can be an economical and efficient method of measuring food service satisfaction in nursing homes and a powerful quality improvement tool. OBJECTIVE: (1) To identify questionnaires that measure food service satisfaction of various stakeholders in a nursing homes and (2) to critically appraise the psychometric properties of identified questionnaires. METHODS: Five electronic databases were searched (Cumulative Index to Nursing and Allied Health Literature, Medline, ProQuest, Scopus, and Cochrane) in April 2020. Data from the eligible studies were extracted, and the psychometric properties were critically appraised using the Consensus-Based Standards for the Selection of Health Measurement Instruments. RESULTS: This review identified 129 studies that used a questionnaire to measure food service satisfaction in nursing homes. Of those, 107 studies representing 75 unique general nursing home satisfaction questionnaires were excluded for failing to adequately explore aspects related to food service. From the remaining 22 studies, 7 food service satisfaction questionnaires were identified; 5 intended for consumers (residents) and 2 intended for organizational stakeholders (staff). Using the Consensus-Based Standards for the Selection of Health Measurement Instruments quality criteria, most questionnaires had flaws in content validity and construct validity, primarily due to small sample sizes. No questionnaires explored food service satisfaction from the family perspective. CONCLUSIONS: Nursing homes collect satisfaction information for accreditation, marketing, benchmarking, and quality improvement. Although questionnaires are easy to administer, the quality of the data they collect is impacted by the validity and reliability of the questionnaires used. Using unreliable satisfaction data may mean that nursing homes are not accurately able to understand the impact of changes in the system on stakeholder satisfaction.

A trial assessing N-3 as treatment for injury-induced cachexia (ATLANTIC trial): does a moderate dose fish oil intervention improve outcomes in older adults recovering from hip fracture?

BACKGROUND: Proximal femoral fractures are associated with increased morbidity and mortality. Pre-existing malnutrition and weight loss amongst this patient group is of primary concern, with conventional nutrition support being largely ineffective. The inflammatory response post proximal femoral fracture surgery and the subsequent risk of cachexia may explain the inability of conventional high energy high protein management to produce an anabolic response amongst these patients. Omega-3 fatty acids derived from fish oils have been extensively studied for their anti-inflammatory benefits. Due to their anti-inflammatory properties, the benefit of fish oil combined with individualized nutrition support amongst proximal femoral fracture patients post surgery is an attractive potential therapeutic strategy. The aim of the ATLANTIC trial is to assess the potential benefits of an anti-inflammatory dose of fish oil within the context of a 12 week individualised nutrition program, commencing seven days post proximal femoral fracture surgery. METHODS/DESIGN: This randomized controlled, double blinded trial, will recruit 150 community dwelling elderly patients aged ≥65 years, within seven days of surgery for proximal femoral fracture. Participants will be randomly allocated to receive either a 12 week individualized nutrition support program complemented with 20 ml/day anti-inflammatory dose fish oil (~3.6 g eicosapentaenoic acid, ~2.4 g docosahexanoic acid; intervention), or, a 12 week individualized nutrition support program complemented with 20 ml/day low dose fish oil (~0.36 g eicosapentaenoic acid, ~0.24 g docosahexanoic acid; control). DISCUSSION: The ATLANTIC trial is the first of its kind to provide fish oil combined with individualized nutrition therapy as an intervention to address the inflammatory response experienced post proximal femoral fracture surgery amongst elderly patients. The final outcomes of this trial will assist clinicians in the development of effective and alternative treatment methods post proximal femoral fracture surgery which may ultimately result in a reduction in systemic inflammation, loss of weight and lean muscle and improvements in nutritional status, mobility, independence and quality of life among elderly patients.
