Background: Sleep disturbance may cause psychotic-like experiences (PLEs). The present study aimed to exam their rate of co-occurrence and investigate whether resilience buffers the association.
Methods: A total of 50,625 junior high school students were assessed using the self-compiled socio-demographics and sleep questionnaires, 8-item Positive Subscale of the Community Assessment of Psychic Experiences, 10-item Connor-Davidson Resilience Scale, Patient Health Questionnaire and Generalized Anxiety Disorder Questionnaire.
Results: In this sample, 15.8% participants had frequent PLEs in the past month, where 40.1% exhibited comorbid sleep disturbance. Sleep disturbance positively associated with the onset of frequent PLEs, after adjusting for socio-demographics, depression and anxiety. Moderation analysis showed resilience buffers the association between sleep disturbance and PLEs, with a higher level of resilience, the positive effect of sleep disturbance on PLEs would be diminished to a greater extent.
Conclusions: These findings suggested that early attention should be drawn to adolescents with sleep disturbance. Intervention strategies should be enhancing resilience, increasing sleep duration and improving sleep quality.

Background: Poor sleep quality due to nocturnal pain is increasingly reported as a major symptom in several shoulder pathologies. Sleep disturbance has been reported in up to 89% after rotator cuff tears and is frequently reported as the primary reason for referring patients to surgery. As a result, it is important to understand the impact of shoulder surgery on a patient's sleep quality.

Background: Pregnancy-related anatomic, physiologic, and hormonal factors can occur at different stages of pregnancy and affect sleep disturbances. The relationship between sleep problems during pregnancy and postpartum depressive symptoms as well as neonatal condition at delivery have not been well described. This study hypothesized that sleep problems are associated with postpartum depressive symptoms and adverse neonatal outcomes at delivery.

Background: Obstructive sleep apnea (OSA) is linked to brain alterations, but the specific regions affected and the causal associations between these changes remain unclear.
Methods: We studied 20 pairs of age-, sex-, BMI-, and education- matched OSA patients and healthy controls using multimodal magnetic resonance imaging (MRI) from August 2019 to February 2020. Additionally, large-scale Mendelian randomization analyses were performed using genome-wide association study (GWAS) data on OSA and 3935 brain imaging-derived phenotypes (IDPs), assessed in up to 33,224 individuals between December 2023 and March 2024, to explore potential genetic causality between OSA and alterations in whole brain structure and function.

It is well established that sleep promotes health and welfare. Literature data suggests that sleep is a recurrent resting state that performs multiple biological functions, such as memory consolidation and regulation of glucose, lipid metabolism, energy metabolism, eating behavior, and blood pressure, besides, regulating the immune system. These immunological functions depend on regular sleep and circadian rhythms, as both impact the magnitude of immune responses.
