Background: The neuropathologic mechanism of primary insomnia (PI) of females remains unclear. This study aims to investigate the features of amplitude of low-frequency fluctuations (ALFF) and regional homogeneity (ReHo) in females with PI using functional magnetic resonance imaging (fMRI), and then explore the abnormalities of functional connectivity (FC).
Materials And Methods: A total of 39 female PI patients and 31 female healthy controls (HC) were enrolled in the study. The sleep condition was assessed using the Pittsburgh Sleep Quality Index (PSQI), and Insomnia Severity Index (ISI), and their depressive symptom was evaluated using the Hamilton Depression Scale (HAMD-24). The rs-fMRI was once conducted for every subject. ReHo, ALFF, and ROI-based FC were used to analyze the changes of brain function.
Results: ALFF values were increased in the Cerebelum_4_5_L, as well as decreased ALFF in the bilateral Frontal_Sup_Medial (SFGmed), Angular_L (ANG.L), Parietal_Inf_R (IPL.R), SupraMarginal_R (SMG.R), and Postcentral_R (PoCG.R). ReHo values were increased in the Temporal_Pole_Mid_R (TPOsup.R), as well as decreased ReHo in the Insula_R (INS.R), Frontal_Inf_Oper_R (ORBinf.R), Putamen_R (PUT.R), Rolandic_Oper_R (ROL.R), bilateral Cingulum_Post (PCG), bilateral Frontal_Sup_Medial (SFGmed), bilateral anterior cingulate and paracingulate gyri (ACG), and the bilateral precuneus (PCUN). Across the entire brain, there was a decline in the FC between Angular_R and Frontal_Sup_Medial_L.
Conclusion: Alterations in brain regions of female patients with PI involved multiple functional networks, including the default mode network, the salience network, the central executive network, and the limbic network. Reduced coordination between functional networks may be an important mechanism for insomnia and may lead to reduced cognitive function and decision-making ability.

Department of Psychiatry, Chungnam National University Hospital, 282 Munhwa-ro, Jung-gu, Daejeon, 35015, South Korea.
Purpose: Comorbid insomnia and obstructive sleep apnea (COMISA) present significant clinical challenges, given their overlapping symptoms and detrimental effects on health. Only a few studies have explored sex differences in patients with obstructive sleep apnea (OSA) and COMISA. This retrospective study investigated sex differences in psychiatric symptoms and polysomnographic findings between patients with COMISA and those with OSA alone.

Background: Evidence supports the common incidence of sleep disturbance in opioid use disorder (OUD) as a potential marker of disrupted orexin system functioning. This study evaluated the initial safety and tolerability of a challenge dose of lemborexant, a dual orexin antagonist, as an adjunct to buprenorphine/naloxone.
Methods: Patients (18-65 years old) with OUD receiving sublingual buprenorphine/naloxone, with a Pittsburgh Sleep Quality Index total score of 6 or higher, were recruited from outpatient clinics.

Department of Chinese Medicine, China Medical University Hospital, Taichung City, 40447, Taiwan.
Background: Recent research has established an association between insomnia and an elevated risk of stroke. Given the severe global impact of stroke on public health, exploring nonpharmacological interventions, such as acupuncture, that can mitigate stroke risk among individuals with insomnia is crucial.
Methods: In this retrospective cohort study, we used data from the Taiwan National Health Insurance Database (NHIRD) to examine the relationship between acupuncture and the risk of stroke among individuals who received a diagnosis of insomnia between 2000 and 2017.

Background: To assess the Knowledge, Attitude, and Practice (KAP) of medical students at Hunan Medicine College towards insomnia and TCM treatment.
Methods: The study included 676 medical students. More than half were female (64.
Study Objectives: 1) To determine the efficacy of Cognitive Behavioral Therapy for Insomnia (CBT-I) for improving insomnia, alcohol-related outcomes, and daytime functioning at post-treatment and at 3- and 6-month follow-up, in a largely African American Veteran sample; 2) Evaluate whether improvement in insomnia is associated with a reduction in alcohol-related outcomes post-treatment.
Methods: An RCT of CBT-I (n = 31) compared to Quasi-Desensitization therapy (QDT, n = 32), eight weekly in-person sessions, with assessments at baseline, end of treatment (8 weeks), and 3- and 6-months post-treatment. Primary outcomes were the Insomnia Severity Index (ISI) total score, and Percent Days Abstinent (PDA).
