Fractal motor activity during wakefulness and sleep: a window into depression recency and symptom recurrence.

Background: Motor activity fluctuations in healthy adults exhibit fractal patterns characterized by consistent temporal correlations across wide-ranging time scales. However, these patterns are disrupted by aging and psychiatric conditions. This study aims to investigate how fractal patterns vary across the sleep-wake cycle, differ based on individuals' recency of depression diagnosis, and change before and after a depressive episode.

In vivo quasi-elastic light scattering detects molecular changes in the lenses of adolescents with Down syndrome.

Down syndrome (DS) is the most common chromosomal disorder in humans. DS is associated with increased prevalence of several ocular sequelae, including characteristic blue-dot cerulean cataract. DS is accompanied by age-dependent accumulation of Alzheimer's disease (AD) amyloid-β (Aβ) peptides and amyloid pathology in the brain and comorbid early-onset Aβ amyloidopathy and colocalizing cataracts in the lens.

Individual-specific change points in circadian rest-activity rhythm and sleep in individuals tapering their antidepressant medication: an actigraphy study.

Group-level studies showed associations between depressive symptoms and circadian rhythm elements, though whether these associations replicate at the within-person level remains unclear. We investigated whether changes in circadian rhythm elements (namely, rest-activity rhythm, physical activity, and sleep) occur close to depressive symptom transitions and whether there are differences in the amount and direction of circadian rhythm changes in individuals with and without transitions. We used 4 months of actigraphy data from 34 remitted individuals tapering antidepressants (20 with and 14 without depressive symptom transitions) to assess circadian rhythm variables.

[PROM a contemporary approach to assessing the quality of life of patients with cancer].

PRO (patient reported outcomes) is a patient's subjective assessment of health and quality of life, without interpretation by a specialist. PROM (patient reported outcomes measure) questionnaires are used to analyzing this data. Assessment of the quality of life is a perspective direction, which allows to improve the quality of medical care and treatment results.

Electronic cigarette vaping with aged coils causes acute lung injury in mice.

Electronic cigarettes (e-cigarettes) have been used widely as an alternative to conventional cigarettes and have become particularly popular among young adults. A growing body of evidence has shown that e-cigarettes are associated with acute lung injury and adverse effects in multiple other organs. Previous studies showed that high emissions of aldehydes (formaldehyde and acetaldehyde) in aerosols were associated with increased usage of the same e-cigarette coils.
