Background & Aims: Many trace elements are nutrients essential to humans, acting in the metabolism as constituents or as enzymatic co-factors. The iron, zinc, copper, manganese and selenium contents of hospital diets (regular, blend and soft) and of oral food complement (OFC) were determined, evaluating the adequacy of each element in relation to the nutritional recommendations (DRIs) and the percent contribution alone and with OFC.
Methods: Duplicate samples were taken of six daily meals and of the OFC on two non-consecutive days from a hospital in Belo Horizonte (MG, Brazil) in May and September of 2010 and January of 2011. The elements were determined by ICP OES.
Results: Of the diets, the soft diet showed the highest elements content. Offering the OFC was insufficient to provide adequate levels of the trace elements.
Conclusion: The oral hospital diets were inadequate in relation to the RDAs for the trace elements studied and the use of the OFCs was insufficient to compensate the values.

Background: Older adults with cognitive impairments will benefit from multicomponent interventions include cognitive training, exercise, and lifestyle modifications. Many digital therapeutic products predominantly focus on computerized cognitive training, lacking effective approaches to other crucial interventions. This study aimed to investigate the long term effects of multidimensional comprehensive cognitive intervention training program - Brain and Body Rehab Training (BBRT), which integrates multidomain cognitive training with physical-cognitive training and multidimensional lifestyle interventions on cognitive performance in participants with cognitive impairment after a 8-month follow-up.

Background: In Zambia, dementia prevalence is unknown due to limited community awareness and a lack of providers skilled in recognizing and diagnosing this disease. Community healthcare workers (CHWs) are widely utilized across sub-Saharan Africa to improve health care access, particularly HIV services. CHWs may be an untapped resource to raise awareness, screen for dementia, and support dementia care in the community.

Background: Caregiver burden, or the impact of caregiving, commonly occurs in caregivers of persons with dementia (PWD); however, prior research focused on caregiver burden in this population has not considered the impact of dysphagia. Therefore, the purpose of this study was to measure dysphagia-specific burden in caregivers of PWD and examine its relationship to general caregiver burden, as well as the PWD's current diet level and dementia severity.
Method: Data were collected from PWD-caregiver dyads participating in a prospective, dysphagia-focused clinical trial at the initial study visit.
