Purpose This paper presents the first standardized physical environmental assessment tool titled Dining Environment Audit Protocol (DEAP) specifically designed for dining spaces in care homes and reports the results of its psychometric properties. Items rated include: adequacy of lighting, glare, personal control, clutter, staff supervision support, restraint use, and seating arrangement option for social interaction. Two scales summarize the prior items and rate the overall homelikeness and functionality of the space. Methods Ten dining rooms in three long-term care homes were selected for assessment. Data were collected over 11 days across 5 weeks. Two trained assessors completed DEAP independently on the same day. Interrater-reliability was completed for lighting, glare, space, homelike aspects, seating arrangements and the two summary scales, homelikeness and functionality of the space. For categorical measures, measure responses were dichotomized at logical points and Cohen's Kappa and concordance on ratings were determined. Results The two overall rating scales on homelikeness and functionality of space were found to be reliable intraclass correlation coefficient (ICC) (~0.7). The mean rating for homelikeness for Assessor 1 was 3.5 (SD 1.35) and for functionality of the room was 5.3. (SD 0.82; median 5.5). Implications The findings indicate that the tool's interrater-reliability scores are promising. The high concordance on the overall scores for homelikeness and functionality is indicative of the strength of the individual items in generating a reliable global assessment score on these two important aspects of the dining space.

Purpose Malnutrition is common in residential care environments, primarily due to poor intake. Micronutrient deficiency, although poorly investigated to date, is also reported to be high. Improving the nutrient density of consumed foods is a potential mechanism to promote increased nutrient intake. A scoping review was conducted to: (1) explore the evidence on micronutrient food fortification strategies, (2) identify candidate nutrients and food vehicles for successful food fortification, and (3) identify gaps for future research. Methods The scoping review framework of Arksey and O'Malley was used. A comprehensive search strategy of 4 electronic databases (MEDLINE, EMBASE, CINAHL, and Web of Science) was completed. Two reviewers were involved in screening and data extraction for all selected articles. Results A total of 4394 relevant articles were identified for screening, and application of inclusion/exclusion criteria resulted in 6 food fortification studies (8 citations; 1 study had 3 citations). Overall, vitamin D (n = 5 studies) and calcium (n = 4 studies) were the most common micronutrients fortified; milk products, margarine, bread, and pureed foods were fortification vehicles. Most studies fortified below the RDA recommendation and did not include clinical outcomes. Samples were small and intervention periods were short (3–6 months). Conclusions Fortification is a viable strategy for improving the nutrient density of foods consumed in residential care. Although disparate, this literature suggests the potential for further undertaking of fortification to prevent micronutrient deficiencies among residents and future research should consider multinutrient preparations and clinical outcomes.

Vitamin B12 (B12) deficiency, although treatable, impacts up to 43% of community-living older adults; long-term care (LTC) residents may be at greater risk. Recommendations for screening require further evidence on prevalence and incidence in LTC. Small, ungeneralizable samples provide a limited perspective on these issues. The purposes of this study were to report prevalence of B12 deficiency at admission to LTC, incidence 1 year post-admission, and identify subgroups with differential risk. This multi-site (8), retrospective prevalence study used random proportionate sampling of resident charts (n = 412). Data at admission extracted included demographics, B12 status, B12 supplementation, medications, diagnoses, functional independence, cognitive performance, and nutrition. Prevalence at admission of B12 deficiency (300 pmol/L). One year post-admission incidence was 4%. Better B12 status was significantly associated with supplementation use prior to LTC admission. Other characteristics were not associated with status. This work provides a better estimate of B12 deficiency prevalence than previously available for LTC, upon which to base protocols and policy. Prospective studies are needed to establish treatment efficacy and effect on health related outcomes.

BACKGROUND AND OBJECTIVES: Poor food intake is common in long-term care (LTC). The mealtime experience has been identified as influential, yet, research has been limited by lack of quality, standardized measures. The purpose of this study was to develop and test for inter-rater reliability the Mealtime Scan (MTS), an observational measure. RESEARCH DESIGN AND METHODS: MTS was derived from the literature on ambiance, mealtime experience, social interactions at mealtimes, and social models of care. Three scales on person-centered care and physical and social environments are used to summarize key aspects observed with MTS. Two raters assessed MTS for reliability at 30 different meals conducted in 10 dining rooms, within three LTC residences. Intraclass correlation coefficient (ICC) was used to assess reliability. RESULTS: MTS demonstrated good to excellent reliability on the three summative scales (physical ICC = 0.73, social ICC = 0.81, person-centered care ICC = 0.83) and other scalable items had good to excellent reliability (e.g., background noise ICC = 0.65, Mealtime Relational Care checklist: negative interactions ICC = 0.85). DISCUSSION AND IMPLICATIONS: MTS is reliable and face valid for assessing mealtime experience. Future work will explore construct validity of this measure. MTS can be used to support improving the mealtime experience for residents living in LTC.

Objectives: Reminiscence is a popular intervention for seniors, but, with mixed evidence supporting its efficacy, questions have been raised about the mechanisms underlying improvement. The present paper addresses this question by investigating the degree to which health effects depend on the development of a shared sense of group identification. This is examined in the context of traditional story-based reminiscence as well as novel forms of song-based reminiscence.Method: As the focus of a manualized intervention, 40 participants were randomly assigned to secular song (n = 13), religious song (n = 13), or standard story reminiscence (n = 14) groups. These were run over six weeks with cognitive performance, anxiety, and life satisfaction measured before and after the intervention. Measures of group fit were included to examine whether social identification contributed to outcomes.Results: No evidence of change emerged over time as a function of intervention form alone, but analysis of identification data revealed significant interactions with the type of reminiscence group. Specifically, initial fit with the story reminiscence group was associated with enhanced cognitive outcomes and greater life satisfaction, while fit with the religious song reminiscence group was associated with greater life satisfaction and less anxiety.Conclusion: These findings show that group identification is a key moderator through which reminiscence promotes health outcomes. Implications for theory and practice highlight an inherent limitation in randomized controlled trials insofar as they may compromise participants group identification.

Cardiovascular monitoring is important to prevent diseases from progressing. The jugular venous pulse (JVP) waveform offers important clinical information about cardiac health, but is not routinely examined due to its invasive catheterisation procedure. Here, we demonstrate for the first time that the JVP can be consistently observed in a non-contact manner using a novel light-based photoplethysmographic imaging system, coded hemodynamic imaging (CHI). While traditional monitoring methods measure the JVP at a single location, CHI's wide-field imaging capabilities were able to observe the jugular venous pulse's spatial flow profile for the first time. The important inflection points in the JVP were observed, meaning that cardiac abnormalities can be assessed through JVP distortions. CHI provides a new way to assess cardiac health through non-contact light-based JVP monitoring, and can be used in non-surgical environments for cardiac assessment., Comment: 10 pages, 8 figures

Photoplethysmography (PPG) devices are widely used for monitoring cardiovascular function. However, these devices require skin contact, which restricts their use to at-rest short-term monitoring. Photoplethysmographic imaging (PPGI) has been recently proposed as a non-contact monitoring alternative by measuring blood pulse signals across a spatial region of interest. Existing systems operate in reflectance mode, many of which are limited to short-distance monitoring and are prone to temporal changes in ambient illumination. This paper is the first study to investigate the feasibility of long-distance non-contact cardiovascular monitoring at the supermeter level using transmittance PPGI. For this purpose, a novel PPGI system was designed at the hardware and software level. Temporally coded illumination (TCI) is proposed for ambient correction and a signal processing pipeline is proposed for PPGI signal extraction. Experimental results show that the processing steps yielded a substantially more pulsatile PPGI signal than the raw acquired signal, resulting in statistically significant increases in correlation to ground-truth PPG in both short- "Equation missing" and long-distance "Equation missing" monitoring. The results support the hypothesis that long-distance heart rate monitoring is feasible using transmittance PPGI, allowing for new possibilities of monitoring cardiovascular function in a non-contact manner.

Mealtime satisfaction is an important component of quality of life (QOL) in residential care, yet there currently is no self-administered tool described in the literature. The purpose of this study is to investigate internal and test–retest reliability, and construct validity of a mealtime satisfaction questionnaire (MSQ) designed for residential care, more specifically retirement homes. A 15-item MSQ was developed and eligible participants from four retirement homes (n = 749) were invited to participate. The participation rate was 24% and the median age was 88 years for respondents. The internal consistency of the MSQ was high (Cronbach Alpha = 0.83) and the test–retest reliability was also high (Intraclass coefficient = 0.91, P
