A feasibility study demonstrating that independence, quality of life, and adaptive behavioral skills can improve in children with Down syndrome after using assistive technology.

Enhancing independence and quality of life are key modifiable outcomes that are short- and long-term goals for children with Down syndrome and for their parents. Here we report the outcome of a 4-week feasibility study in a cohort of 26 children with Down Syndrome, 7-17 years old, who used an assistive technology approach that incorporated smart device software and step-by-step pictures (the MapHabit System). Parents reported improvements in children's activities of daily living, quality of life, and independence. They recommended this technology to other families. This report and its findings underscore the feasibility of using assistive technology in children with Down syndrome within home and family settings. A limiting factor is whether participants who did not complete the study, and thus were not included in analyses, might have impacted the study outcomes. The current findings that assistive technology can be used successfully and effectively in family and home settings set the stage for more informative systematic studies using assistive technology for this population. Trial registration: The clinical trial is registered with ClinicalTrials.gov Registration number: NCT05343468.

A systematic review of acculturation and sleep health among adult immigrants in the United States.

The United States (US) has more immigrants than any other country in the world, with an estimated 44 million non-US-born individuals residing in the country as of 2018. Previous studies have linked US acculturation to both positive and negative health outcomes, including sleep. However, the relationship between US acculturation and sleep health is not well understood. This systematic review aims to identify and synthesize scientific studies on acculturation and sleep health among adult immigrants in the US. A systematic search of the literature was performed in PubMed, Ovid MEDLINE, and Web of Science in 2021 and 2022 with no date limiters. Quantitative studies published anytime in a peer-reviewed journal in English among an adult immigrant population with an explicit measure of acculturation and a sleep health dimension, sleep disorder, or daytime sleepiness measure were considered for inclusion. The initial literature search yielded 804 articles for review; after removing duplicates, applying inclusion and exclusion criteria, and searching reference lists, 38 total articles were included. We found consistent evidence that acculturative stress was associated with worse sleep quality/continuity, daytime sleepiness, and sleep disorders. However, we discovered limited consensus on the association of acculturation scales and acculturation proxy measures with sleep. Our review demonstrated that compared to US-born adult populations, there is a high prevalence of adverse sleep health among immigrant populations, and acculturation likely plays an important role in shaping this disparity, particularly through acculturative stress.

A Feasibility Study of Individuals Living at Home with Alzheimer's Disease and Related Dementias: Utilization of Visual Mapping Assistive Technology to Enhance Quality of Life and Reduce Caregiver Burden.

Efficacy of assistive technology continues to evolve as a means of helping individuals with cognitive and intellectual disabilities, asserting the importance of its research. We report outcomes of a six-week randomized control feasibility study in a small cohort of 16 family caregivers of individuals living with Alzheimer's disease and related dementias. An experimental group of seven family caregivers used visual mapping software on smart devices (step-by-step pictures, audio, and videos instructing how to complete a task) to support carrying out activities of daily living with their care recipients. In comparison, control group of nine family caregivers used smart devices to access and view educational videos focused on dementia care. After a six-week study, compared to caregivers using educational videos, caregivers using visual maps assistive technology reported higher satisfaction of use and stronger recommendation of use to others. Caregivers using visual maps technology also exhibited more improved quality of life scores and improved completion of activities of daily living for their dementia care recipients, as well as reduced caregiver burden scores compared to the caregivers in the control group. These promising findings show that the use of assistive technology is feasible in the home setting and suggest time is ripe for undertaking systematic studies of assistive technology's potential to advance effective behavioral interventions in dementia home and family settings.

Reduced care burden and improved quality of life in African American family caregivers: Positive impact of personalized assistive technology.

BACKGROUND: African Americans living with dementia are considered less likely to seek formal institutionalized elder care and more likely to be managed in the home by family-member caregivers. Assistive technologies (the use of smart visual devices like tablets and phones) can be used effectively to guide memory-impaired individuals with a sequence of pictures showing steps to complete activities of daily living, e.g., bathing, toileting, dressing. Assistive technology so far has not been generally embraced in African American communities. OBJECTIVES: Determine, if African American family caregivers, given the opportunity, would embrace the use of assistive technology and if they would perceive its use beneficial. METHODS: We assessed a group of eight family caregivers' overall care-burden scores, and their user-satisfaction scores after using assistive technology for three months. RESULTS: We found significant reduction in caregiver burden, positive changes in behavior and emotion scores, and high ratings on user satisfaction. CONCLUSIONS: The findings reported here comprise the first systematic study of the use of assistive technology by caregivers in an underserved population. They set the stage for exploring meaningful strategies and variables that will better engage underserved populations to take advantage of assistive technologies available in healthcare.

Burden of sleep disturbance in non-Hispanic Black pregnant women.

STUDY OBJECTIVES: Non-Hispanic Black pregnant women disproportionately experience poor perinatal outcomes compared to other racial/ethnic groups. Sleep disruption has emerged as a risk factor for adverse pregnancy outcomes, but there are limited data in minority pregnant women. We examined the prevalence of habitual snoring and its timing of onset with several key sleep-wake disturbances and their associations with perinatal outcomes in a cohort of non-Hispanic Black pregnant women. METHODS: Non-Hispanic Black pregnant women in their third trimester were recruited from a large academic medical center and screened for habitual snoring and its timing relative to pregnancy, along with sleep quality, symptoms of insomnia, excessive daytime sleepiness, and daytime function. Clinical diagnoses of hypertensive disorders of pregnancy were obtained along with delivery outcomes. RESULTS: In 235 women, the vast majority (80%) reported 3 or more sleep-wake disturbances, and almost half had at least 5 disturbances. Sixteen percent reported prepregnancy snoring and 20% reported pregnancy-onset snoring. Women with pregnancy-onset snoring had significantly increased odds of poor sleep quality (adjusted odds ratio [aOR] = 8.2), trouble staying asleep (aOR = 3.6), waking up too early (aOR = 2.7), excessive daytime sleepiness (aOR = 2.3), and poor daytime function (aOR = 8.7) but no relationship with perinatal outcomes. In contrast, prepregnancy snoring was related to chronic hypertension, preterm delivery, and fetal growth restriction (aOR = 2.6, aOR = 2.8, and aOR = 5.1, respectively). CONCLUSIONS: Sleep-wake disturbances confer a significant burden to pregnant non-Hispanic Black women, an infrequently studied yet disproportionately affected population. Contributions of maternal sleep to racial disparities in perinatal health should be a priority for public health research.

Innate Lymphoid Cells Mediate Pulmonary Eosinophilic Inflammation, Airway Mucous Cell Metaplasia, and Type 2 Immunity in Mice Exposed to Ozone.

Exposure to elevated levels of ambient ozone in photochemical smog is associated with eosinophilic airway inflammation and nonatopic asthma in children. In the present study, we determined the role of innate lymphoid cells (ILCs) in the pathogenesis of ozone-induced nonatopic asthma by using lymphoid cell-sufficient C57BL/6 mice, ILC-sufficient Rag2-/- mice (devoid of T and B cells), and ILC-deficient Rag2-/-Il2rg-/- mice (depleted of all lymphoid cells including ILCs). Mice were exposed to 0 or 0.8 parts per million ozone for 1 day or 9 consecutive weekdays (4 hr/day). A single exposure to ozone caused neutrophilic inflammation, airway epithelial injury, and reparative DNA synthesis in all strains of mice, irrespective of the presence or absence of ILCs. In contrast, 9-day exposures induced eosinophilic inflammation and mucous cell metaplasia only in the lungs of ILC-sufficient mice. Repeated ozone exposures also elicited increased messenger RNA expression of transcripts associated with type 2 immunity and airway mucus production in ILC-sufficient mice. ILC-deficient mice repeatedly exposed to ozone had no pulmonary pathology or increased gene expression related to type 2 immunity. These results suggest a new paradigm for the biologic mechanisms underlying the development of a phenotype of childhood nonatopic asthma that has been linked to ambient ozone exposures.
