Background: Age-related decline in vision may contribute to the development of fear of falling (FOF) behavior and reduced mobility, which are related to increased fall risk in older adults.
Purpose: To investigate the inter-relationship between vision impairment, physical mobility performance, and FOF behavior in community-dwelling older adults.
Methods: A total of 400 participants from community centers (267 females; age = 74.8 (6.4), range = 65-97 years) participated in this cross-sectional study. Presence of age-related eye diseases (e.g. macular degeneration, cataracts, glaucoma, and retinopathy) and visual acuity (VA) was assessed. Physical mobility and FOF avoidance behavior were assessed using the Timed Up-and-Go (TUG) test and the Fear of Falling Avoidance Behavior Questionnaire (FFABQ). The inter-relationships between parameters were analyzed using mediation model analysis.
Results: Significant decreases in mobility performance were observed in those with eye disease (eye disease = 9.56 [5.2] sec, no eye disease = 8.54 [2.75] sec; = .037) and FOF avoidance behavior (avoiders = 12.87 [6.04] sec, non-avoiders = 8.51 [3.56] sec; < .001). Furthermore, FOF behavior was found to significantly influence the inter-relationship between presence of eye disease and TUG performance ( = .004). VA alone had no significant effect on mobility ( = .69).
Conclusion: The presence of eye disease and the associated FOF behavior was related to decreased mobility and potentially increased fall risk. We recommend clinicians to inquire about the presence of eye disease and FOF behavior to identify risk factors related to falls in older adults.

Recent research has identified sex-dependent links between risk taking behaviors, approach-avoidance bias and alcohol intake. However, preclinical studies have typically assessed alcohol drinking using a singular dimension of intake (i.e.

Background: Skin-picking disorder (SPD) is currently conceptualized as a condition related to obsessive-compulsive disorder (OCD). The present study investigated whether the emotional, cognitive, and somatic components of skin-picking episodes align with this conceptual framework.
Method: A total of 134 patients diagnosed with SPD (mean age = 32 years; 84 % female; average symptom duration: 16 years) underwent in-person clinical assessment.

Background: Post-traumatic stress disorder (PTSD) is a serious psychiatric disorder that occurs after an individual has witnessed or experienced a major traumatic event. Emotional contagion seems to play an important role in witnessing trauma, highlighting the importance of understanding the neurobiological consequences of psychological or emotional stress and its impact on the individual's mental health. Therefore, understanding the relationship between emotional contagion and PTSD susceptibility and the abnormal neurobiological and behavioral changes behind it could help find effective molecular treatment targets.

Healthcare avoidance or delays for wounds and related skin- and soft-tissue infections are often attributed to negative interactions with medical providers. An infrastructural violence framework posits that healthcare infrastructure serves as a material channel for structural violence, maintaining inequities in healthcare experiences and outcomes. Infrastructural violence ensues when infrastructure is designed for some members or groups within a society while perpetuating violence among others.
