Background: Fatigue is a prominent symptom in many diseases and is strongly associated with impaired daily function. The measurement of daily function is currently almost always done with questionnaires, which are subjective and imprecise. With the recent advances of digital wearable technologies, novel approaches to evaluate daily function quantitatively and objectively in real-life conditions are increasingly possible. This also creates new possibilities to measure fatigue-related changes of daily function using such technologies.
Summary: This review examines which digitally assessable parameters in immune-mediated inflammatory and neurodegenerative diseases may have the greatest potential to reflect fatigue-related changes of daily function.
Key Messages: Results of a standardized analysis of the literature reporting about perception-, capacity-, and performance-evaluating assessment tools indicate that changes of the following parameters: physical activity, independence of daily living, social participation, working life, mental status, cognitive and aerobic capacity, and supervised and unsupervised mobility performance have the highest potential to reflect fatigue-related changes of daily function. These parameters thus hold the greatest potential for quantitatively measuring fatigue in representative diseases in real-life conditions, e.g., with digital wearable technologies. Furthermore, to the best of our knowledge, this is a new approach to analysing evidence for the design of performance-based digital assessment protocols in human research, which may stimulate further systematic research in this area.

The ability to navigate through one's environment is crucial for maintaining independence in daily life and depends on complex cognitive and motor functions that are vulnerable to decline in persons with Multiple Sclerosis (MS). While previous research suggests a role for mobility in the physical act of navigation, it remains unclear to what extent mobility impairment and perceptions of mobility constraints may modify wayfinding and the recall of environment details in support of successful navigation. Therefore, this study examined the relations among clinical mobility function, concern about falling, and recall of environment details in a clinical sample of MS.

» Kim's lesion of the shoulder is characterized by incomplete tearing of the junction between the posteroinferior labrum and the glenoid, with the superficial labral tissue remaining intact, and generally requires arthroscopic evaluation for accurate confirmation.» Kim's lesion represents an under-reported subtype of posterior labral injury and a source of activity-related posterior shoulder discomfort and instability.» Kim's lesions are frequently observed in young, active individuals involved in overhead and contact sports, often resulting from traumatic mechanisms with the shoulder in flexion and adduction, as well as from repetitive microtrauma and overuse.

Background: Children with conduct problems vary considerably in how they respond to behavioral interventions. Although group-based, child-focused programs are increasingly implemented, research still relies on retrospective parent or teacher reports and group-level outcomes. These traditional approaches often obscure individual differences in treatment response and reduce the potential for individualized behavioral support tailored to each child's unique profile.

Current therapeutics for hypoxic/ischemic brain damage can benefit from insights resulting from the study of hypoxia/anoxia resistant organisms. Hypoxia resistance, however, is not a common feature in mammalian models. Being naturally exposed to hypoxic/anoxic conditions, the sea hare could become a very useful model for the study of hypoxia resistance.

Ultraviolet B (UVB) radiation (280-320 nm) has been recognized as a carcinogen since 1928, leading to sun exposure minimization. However, epidemiological studies suggest that sun exposure correlates with increased life expectancy and reduced incidence of cardiovascular diseases and certain cancers such as colon and endometrial cancer. UVB exposure also influences liver metabolism, protects against hepatocellular lipotoxicity, and affects metabolic health.
