Background. Mindfulness-based interventions (MBIs) have emerged as an alternative intervention for symptoms of psychological and psychiatric conditions, such depression, anxiety, emotional discomfort. Over the last ten years, MBIs established a growing body evidence that shows cognitive neurophysiological benefits. Depression anxiety are conditions with high prevalence in world population. In developing countries, it is reported that, given being at social disadvantage, depression higher, resulting compromised well-being mental health. Objectives. This systematic review aims to quantitatively qualitatively assess changes neuropsychological, particularly executive functioning cognition domains, electroencephalographical (EEG) effects MBIs. Methods. A was conducted using Preferred Reporting Items Systematic Reviews Meta-Analyses (PRISMA) three databases, Web Science, Scopus, EBSCO MedLine complete; 14,464 articles were found, 141 evaluated MBI on functioning, 16 included both qualitative quantitative variables.

The goal comprehensively evaluate infection these different demographics. analyzed EEG changes by potential biomarkers groups using both spatial temporal approaches.

Abstract Background Long‐term nutritional and functional status after hospitalization due to COVID‐19 has been poorly described. We show the physical stata symptoms compatible with Long‐COVID in patients who survived an episode of associated factors. Methods Single‐center prospective observational study. Clinical, nutritional, function data were assessed 345 subjects over 18 years age hospitalized university hospital for a diagnosis 2020 at three different times follow‐up: 6 ( n = 118), 9 115), 15 months 112) discharge. All survivors discharged during each those periods called consecutively follow‐up order collect about their stata, long‐COVID symptoms.

The Use of a Voice-Based Digital Mindfulness App to Facilitate Self-perceived Bodily and Emotional Well-Being among Older Adults: A Mixed Method Study (Preprint)

Опубликована: Окт. 14, 2024

Mindfulness-based interventions have been demonstrated to be an effective method improve bodily and emotional well-being, but few studies explored individual differences heterogeneity in the self-perceived benefits of digital mindfulness among older adults aged 65 above. Although voice-based technologies can increase accessibility training, expected effects may not similar all user groups. Digital health are often used by individuals with a high literacy. The study investigates what extent app well-being (aged above), how incorporate their daily routines, different interaction modalities impacts experience. A mixed combining quantitative survey questionnaires qualitative semi-structured interviews was conducted over who for 3-week period homes Sweden (N=15). on were measured Five Facets Mindfulness Questionnaire, WHO5 Well-being Index, which analysed through descriptive statistics. Qualitative content analysis explore mindfulness, engagement app. Results WHO-5 index showed overall improvement mean values results from Questionnaire 11 15 questions, particularly non-reactivity. Younger participants (under 76) those evaluated as reported higher improvements scale after use. Due small sample size, these statistically significant. identified four main themes benefits: (1) Relaxation breathing, (2) Improved awareness, (3) awareness (4) Pain management. Participants described that continuity temporality use significant noticing mindfulness.
