Despite many available treatment options for depression, response rates remain suboptimal. To improve outcome, circadian markers may be suitable as markers of treatment response. This systematic review provides an overview of circadian markers that have been studied as predictors of response in treatment of depression. A search was performed (EMBASE, PUBMED, PSYCHINFO) for research studies or articles, randomized controlled trials and case report/series with no time boundaries on March 2, 2024 (PROSPERO: CRD42021252333). Other criteria were; an antidepressant treatment as intervention, treatment response measured by depression symptom severity and/or occurrence of a clinical diagnosis of depression and assessment of a circadian marker at baseline. 44 articles, encompassing 8,772 participants were included in the analysis. Although additional research is needed with less variation in types of markers and treatments to provide definitive recommendations, circadian markers, especially diurnal mood variation and chronotype, show potential to implement as response markers in the clinic.

Beyond sleep: Rest and activity rhythm as a marker of preclinical and mild dementia in older adults with less education.
Neurobiol Sleep Circadian Rhythms

Division of Geriatrics, University of São Paulo Medical School, São Paulo, Brazil.
Background: Although sleep duration and sleep-related breathing disorders were associated with dementia previously, few studies examined the association between circadian rhythm association and cognitive status.
Objective: We aimed to investigate the association of rest and activity rhythm with cognitive performance in older people with cognitive complaints and less education.
Methods: Activity rhythm was evaluated with wrist actigraphy in 109 community-dwelling older people with cognitive complaints without diagnosed dementia.

Circadian rhythms of metabolic, hormonal, and behavioral fluctuations and their alterations can impact health. An important gap in knowledge in the field is whether the time of the day of exercise and the age of onset of exercise exert distinct effects at the level of whole-body adipose tissue and body composition. The goal of the present study was to determine how exercise at different times of the day during adolescence impacts the adipose tissue transcriptome and content in a rodent model.

Lithium has long been used as a cornerstone mood stabilizer in the treatment of bipolar disorder (BD). However, reliable biomarkers that can predict which patients will respond better to lithium are still lacking. This study aims to evaluate the potential of NR1D1 gene SNP; rs2071427 and actigraphic measurements in predicting lithium response.

Introduction: Obesity is a multifactorial disease caused by an interaction between genetic, environmental and behavioral factors. Polymorphisms of the two genes Circadian Locomotor Output Cycles Kaput (CLOCK) rs1801260 and Melanocortin-4-receptor (MC4R) rs17782313, are associated with obesity. Knowledge is limited on the interaction between CLOCK, MC4R and obesity.
