The pineal hormone Melatonin plays an important role in the regulation of the circadian sleep/wake cycle, mood, and perhaps immune functions, carcinogensis and reproduction. The human circadian rhythm of melatonin release from the pineal gland is tightly synchronized with the habitual hours of sleep. Peri- and postmenopausal women often complain of difficulties initiating and/or maintaining sleep, with frequent nocturnal and early morning awakenings. In this review we discuss the pathophysiology of melatonin function as it relates to sleep disorders in menopausal women, highlighting the potential use of exogenous melatonin during the menopausal transition and beyond.

Although sleep apps are among the most popular commercially available health apps, little is known about how well these apps are grounded in behavioral theory. Three-hundred and sixty-nine apps were initially identified using the term “sleep” from the Google play store and Apple iTunes in September 2015. The final sample consisted of 35 apps that met the following inclusion criteria: 1) Stand-alone functionality; 2) Sleep tracker or monitor apps ranked by 100 + users; 3) Sleep Alarm apps ranked by 1000 + users; and 4) English language. A coding instrument was developed to assess the presence of 19 theoretical constructs. All 35 apps were downloaded and coded. The inter-rater reliability between coders was 0.996. A “1” was assigned if a construct was present in the app and “0” if it was not. Mean scores were calculated across all apps, and comparisons were made between total scores and app ratings using R. The mean behavior construct scores (BCS) across all apps was 34% (5% - 84%). Behavioral constructs for realistic goal setting (86%), time management (77%), and self-monitoring (66%) were most common. Although a positive association was observed between BCS and user ratings, this was not found to be statistically significant (p > 0.05). The mean persuasive technology score was 42% (20% to 80%), with higher scores for paid compared to free apps (p < 0.05). While the overall behavior construct scores were low, an opportunity exists to develop or modify existing apps to support sustainable sleep hygiene practices.

Obstructive sleep apnea (OSA) is a global disease with a rising incidence along with its comorbidities, especially with metabolic syndrome. One of the main components contributing to sleep apnea is obesity; as well as diabetes mellitus type 2 (T2DM), hypercholesterolemia, and hypertension. OSA is a condition that requires management and the disease can be treated by using CPAP therapy. The awareness of this global issue is rising, and health care systems are providing preventive measures, diagnosis and the treatment options. The major preventable risk factors to decrease obesity are the awareness of lifestyle modification (eating behaviors, smoking, drinking alcohol, etc.) and understanding the importance of exercise. If these lifestyle modifications are widely applied, then not only will the consequences of obesity and sleep apnea be reduced, but also the incidence of cardiovascular disease will decrease greatly. Public awareness of the importance of weight loss by lifestyle modification or bariatric surgery to improve the quality of life is needed. These preventive actions, screening measures, and treatment strategies for obesity and OSA can significantly reduce the incidence of obesity, as well as OSA and the related comorbidities such as cardiovascular disease, atherosclerosis, and depression. Finally, health care costs will also be reduced.

Microaggressions are a common way that individuals experience racism in the United States. The current study examined the extent to which microaggressions contribute to mental health difficulties, namely trauma reactions and depression, after controlling for other traumatic event exposures. We sought to address gaps in the literature by quantitatively assessing the associations among microaggressions, posttraumatic stress symptoms, and depression symptoms. Participants were 140 young adults of color (68.8% female) who were recruited online. Linear regression analyses evidenced that microaggressions were uniquely associated with depression symptoms, B = 0.27, after controlling for lifetime traumatic event exposures, with this association partially mediated by trauma reactions, B = 0.49. These results suggest that microaggressions are a clinically relevant factor in understanding mental health problems reported by Black, Indigenous, and People of Color in the United States and warrant analysis, assessment, and intervention through a trauma lens.
