Objectives: Sleep disturbances negatively impact the quality of life of patients with Parkinson's disease (PD). While persons living in regional areas are at higher risk of PD, PD is poorly managed in regional communities. This study examined factors associated with sleep problems in PD in a regional context.
Design: A mixed-methods cross-sectional design was used.
Participants: Patients with PD were recruited from the Queensland Parkinson's Project database.
Measurements: Those who agreed to participate were sent a questionnaire assessing aspects of sleep, depression, anxiety, quality of life, and PD severity. Qualitative information was also gathered. Correlations between variables were examined; thematic analyses were performed for qualitative data.
Results: All participants (n = 49) reported sleep disturbances, with 73% (n = 36) reporting sleep disturbance to be problematic. Global sleep dysfunction positively correlated with daytime napping (r = .34, p = .01), watching the clock when unable to sleep (r = .38, p = <.01), staying in bed when unable to sleep (r = .43, p = <.01), and going to bed hungry (r = .31, p = .03) and negatively correlated with daytime exercise (r = -.32, p = .02). Positive correlations were observed between global sleep dysfunction and depression (r = .55, p = <.01), anxiety (r = .31, p = .04), and dysfunctional sleep beliefs (r = .39, p = <.01).
Conclusion: There is a clear need for identifying factors related to sleep disturbances in PD for effective management.

Background: Many cancer survivors experience a wide range of symptoms closely linked to psychological problems, highlighting the need for psychological treatment, one of the most popular being mindfulness. The use of the internet has greatly increased in the last decade, and has encouraged the use of remote-based interventions to help people living with cancer access treatment remotely via devices.
Objective: The primary aim of this study was to explore the efficacy of internet-based mindfulness interventions on the physical symptoms of people living with cancer, where physical symptoms are defined as distressing somatic experiences (eg fatigue, insomnia, and pain) regardless of the underlying cause.
Itching tends to worsen at night in patients with itchy skin diseases, such as atopic dermatitis. Unconscious scratching during sleep can exacerbate symptoms, cause sleep disturbances, or reduce quality of life. Therefore, evaluating nocturnal scratching behaviour is important for better patient care.

Background: Menopause is a significant phase in women's health, in which the incidence of obstructive sleep apnea (OSA) is significantly increased. Body fat distribution changes with age and hormone levels in postmenopausal women, but the extent to which changes in body fat distribution affect the occurrence of OSA is unclear.
Methods: This research performed a cross-sectional analysis utilizing data from the 2015-2016 National Health and Nutrition Examination Survey (NHANES).
