Summary: Sleep disorders and circadian dysrhythmias are common in critically ill patients, impacting prognosis. Despite scientific findings, sleep optimization is not a top priority in the ICU. Measuring and evaluating sleep in the ICU is challenging, and treatment focuses on non-pharmacologic and pharmacologic strategies, with pharmacological interventions alone being insufficient.

Summary: The study found that asthma patients experience worsened lung function and exacerbation of symptoms at night, often masked by sleep. Asthma patients exhibit significant circadian rhythms throughout the day and are more likely to use bronchodilators during the night.

Summary: The study revealed the effects of blue light on sleep and emotions in mice, showing that blue light can induce delays in sleep and arousal-promoting responses, as well as depressive-like emotions. Molecular changes indicated the involvement of specific brain regions in the blue light-induced response processes.

Summary: Sleep and circadian rhythms disturbances (SCRD) in young people at high risk or with early onset of bipolar disorders (BD) are poorly understood. Studies have shown that individuals with presentations meeting recognised BD-at-risk criteria (BAR) have a greater preference for eveningness and more dysregulation of social rhythms. Pre-existing SCRD were found to be associated with a 40% increased risk of onset of BD.

Summary: Deficiency of SIK3 in GABAergic neurons or NMS-producing neurons delays the arousal peak phase, while a gain-of-function mutant allele of Sik3 in GABAergic neurons advances the activity onset. Furthermore, HDAC4 deficiency shortens the circadian cycle.

Summary: The study found that cognitive and physical activities are dominated by diurnal and infra-radian rhythms, but cognitive performance has a weaker rhythm than physical activity. Before bedtime, people continue to interact with their smartphones while at physical rest, leading to a decline in cognitive performance.

Summary: The bidirectional relationship between sleep disturbances and affective disorders is not well understood. This study aims to investigate the sleep disturbances in recurrent depressive disorder (RDD) and bipolar affective disorder (BPAD) using polysomnographic and clinical records. Although no significant differences in sleep macrostructure parameters were found between BPAD and RDD patients, BPAD patients had higher comorbid sleep and physical disorders. Obstructive sleep apnea and insomnia were significantly linked to BPAD.

Summary: The study demonstrates that hugin(+) neurons play a critical role in regulating sleep homeostasis by integrating circadian and sleep signals to modulate circadian circuitry and regulate the timing of sleep. Sleep deprivation reduces the activity of hugin(+) neurons, while ablation of these neurons increases sleep promoted by activation of the homeostatic sleep locus, the dorsal fan-shaped body (dFB). This suggests a complex interaction between sleep and circadian rhythms mediated by hugin(+) neurons.

Summary: A systematic review and meta-analysis revealed a negative relationship between sleep disorders and male semen parameters (total sperm count, sperm concentration, progressive motility, and normal morphology), but no significant association with semen volume or reproductive hormone levels. Further bioinformatics mining suggested that clock genes may play a role in this association.

Summary: This study aimed to analyze the influence of mothers' nighttime responses on the sleep-wake rhythm of their 1-month-old infants. Findings showed that immediately picking up 1-month-old infants may result in longer daytime sleep compared to nighttime sleep, possibly due to the stimulating effects of picking up the infant on sleep-wake rhythm formation.

Summary: Sleep disorders appear to be more common in women, while sex-related differences exist for dreams and nightmares. Differences related to dreams include dream content, self-reported perspective, dream sharing, lucid dreaming, and daydreaming. Nightmares are more frequent in women and are often associated with sleep disorders and psychiatric disorders like depression and anxiety.

Summary: By studying a large group of MDD patients and controls using fMRI data, differences in functional connectivity in patients were identified. Baseline connectivity of the anterior/posterior cingulate and insula seeds could differentiate patients with different treatment outcomes, highlighting features that might predict remission prior to pharmacotherapy.

Summary: The study examines the experiences and satisfaction levels of Canadian mental health care users and providers with remote care during the COVID-19 pandemic. The majority of participants expressed satisfaction with remote care, highlighting the convenience and speed of provision. However, all groups were least satisfied with therapeutic rapport. The use of video-based platforms and attention to visual cues were associated with higher user satisfaction. Most participants reported a likelihood of continuing to use remote care after the pandemic.

Summary: The neurobiological correlates of response inhibition can predict the response of patients with major depressive disorder (MDD) to pharmacological and cognitive behavioral therapy treatment. The integrity of response inhibition may be crucial for the success of treatment for MDD. Electrophysiological correlates of response inhibition may serve as a general prognostic marker for treatment response in MDD.

Summary: Major depressive disorder (MDD) is the leading cause of disability worldwide, and comorbid chronic pain exacerbates disability and healthcare burden. Managing patients with both MDD and chronic pain can be challenging due to shared underlying mechanisms. Current treatment guidelines address comorbid conditions such as anxiety and cardiovascular disease, but not chronic pain. Rapidly and aggressively treating depression according to guideline recommendations, using antidepressants with analgesic properties, while also addressing pain, is recommended based on clinical experience.

Summary: Cytochrome P450 drug-metabolizing enzymes, specifically CYP2C19 and CYP2D6 gene variants, have an impact on antidepressant outcomes. Poor metabolizers of CYP2C19 and CYP2D6 show less symptom improvement during treatment with escitalopram alone and are more likely to experience central nervous system side effects when taking escitalopram alone or in combination with aripiprazole.

Summary: In this study, the association between six ABCB1 single-nucleotide polymorphisms (SNPs) and antidepressant treatment outcomes was investigated through a systematic review and meta-analysis. No significant association was found between ABCB1 SNPs and antidepressant treatment outcomes in the CAN-BIND-1 sample. However, a significant association between rs1128503 and treatment response was observed in the meta-analysis. These findings provide limited evidence for the implementation of ABCB1 genotyping to inform antidepressant treatment.

Summary: This study aimed to develop the first prototype VR cognitive remediation program for MDD and gathered qualitative data from end users to enhance its efficacy and feasibility. The results showed optimism towards VR as a treatment modality and a need for engaging and customizable VR treatment. Some skepticism regarding its effectiveness and concerns regarding equipment accessibility were also reported.

Summary: This study aims to investigate the differential associations of different types of childhood maltreatment with the response to antidepressant medication, and the role of anhedonia in driving poor response in patients with specific maltreatment histories. The results suggest that the severity of emotional maltreatment perpetrated by the mother is a significant predictor of lower odds of remission at week 16. In contrast, the relationships between paternal-perpetrated emotional maltreatment and physical maltreatment with week 16 remission were mediated through the severity of anhedonia at week 8.

Summary: The study used Rasch Measurement Theory to evaluate the measurement properties of the Quick Inventory of Depressive Symptomatology Self-Report (QIDS-SR) in neurodegenerative disorders (ND) and major depressive disorder (MDD). The results showed that the QIDS-SR is suitable for assessing and screening depressive symptoms in persons with ND, but there are limitations in differentiating participants at certain severity levels.
