Abstract

Sleep disruption is common among older adults. Non-pharmacological interventions involving music has emerged as a promising approach to address sleep disruption. The purpose of this systematic review was to examine the effects of music interventions on sleep outcomes among older adults (age ≥ 50). We searched five databases through May 2020 and found 16 eligible studies focused on two types of music interventions: music listening (n = 11) and multi-component (n = 5). We found mixed evidence in the efficacy of music interventions to improve sleep outcomes in older adults, which included sleep quality, objective and subjective sleep characteristics. Music listening interventions contained relaxing music with research teams personalizing music choice based on participants’ preferences. Multi-component interventions included listening to music in addition to one other approach, such as massage, tai chi, and nature scenes. Future higher-quality studies should provide a detailed description of music interventions and tailor music selections to older adults’ preferences.

Abstract

Sleep disruption in persons with dementia is pervasive and contributes to negative health outcomes and decreased quality of life. Using Lawton’s framework for quality of life in persons with dementia, the aim of this state-of-the-art review was to synthesize current knowledge on the association between sleep disruption and quality of life in persons with dementia in four domains: physical, social/behavioral, emotional well-being, and cognitive. Based on the final sample of six studies, sleep disruption was negatively associated with all four quality of life domains in persons with dementia. Given the variations in research design, measurement and sample size, conclusions could not be generated on the magnitude of the effects by domain. We do, however, provide recommendations for future research and clinical practice.

Abstract

Melanomas can have multiple co-existing cell states, including proliferative (PRO) versus invasive (INV) subpopulations that represent a “go or grow” tradeoff; however, how these populations interact is poorly understood. Using a combination of zebrafish modeling and analysis of patient samples we show that INV and PRO cells form spatially structured heterotypic clusters and cooperate in the seeding of metastasis, maintaining cell state heterogeneity. INV cells adhere tightly to each other, and form clusters with a rim of PRO cells. Intravital imaging demonstrated cooperation in which INV cells facilitate dissemination of less metastatic PRO cells. We identified the TFAP2 neural crest transcription factor as a master regulator of clustering and PRO/INV states. Isolation of clusters from patients with metastatic melanoma revealed a subset with heterotypic PRO-INV clusters. Our data suggest a framework for the co-existence of these two divergent cell populations, in which heterotypic clusters promote metastasis via cell-cell cooperation.

Abstract

Permeable reactive barrier (PRB) technology, in which sulfate-reducing bacteria (SRB) facilitate precipitation of metal sulfides, is a promising approach for remediation of sulfate- and metal-laden mine drainage. While PRBs are easily established, they often decline for reasons not well understood. SRB depend on or compete with multiple dynamic microbial populations within a PRB; as a result, performance depends on the changing PRB chemical composition and on succession and competition within the microbial community. To investigate these interactions, we constructed and monitored eight bench-scale PRBs to define periods of establishment, performance, and decline. We then conducted short-term batch studies, using substrate-supplemented column materials, on Days 0 (pre-establishment), 27 (establishment), 41 (performance), and 99 (decline) to reveal potential activities of cellulolytic bacteria, fermenters + anaerobic respirers, SRB, and methanogens. PRBs showed active sulfate reduction, with sulfate removal rates (SRR) of ∼1–3 mol/m 3 /d, as well as effective removal of Zn 2+ . Potential activities of fermentative + anaerobic respiratory bacteria were initially high but diminished greatly during establishment and dropped further during performance and decline. In contrast, potential SRB activity rose during establishment, peaked during performance, and diminished as performance declined. Potential methanogen activity was low; in addition, SRB-methanogen substrate competition was shown not to limit SRB activity. Cellulolytic bacteria showed no substrate limitation at any time. However, fermenters experienced substrate limitation by Day 0, SRB by Day 27, and methanogens by Day 41, showing the dependence of each group on upstream populations to provide substrates. All potential activities, except methanogenesis, were ultimately limited by cellulose hydrolysis; in addition, all potential activities except methanogenesis declined substantially by Day 99, showing that long-term substrate deprivation strongly diminished the intrinsic capacity of the PRB community to perform.
