Menstrual cycle phases and dosage of synthetic hormonal contraceptives influence diurnal rhythm characteristics of distal skin temperature
In conclusion, monophasic OC cause changes in diurnal DST rhythm, similar to those observed in the luteal phase of females with menstrual cycles, suggesting that synthetic progestins act in a similar manner on skin thermoregulation as progesterone does.PMID:38634452 | DOI:10.1080/07420528.2024.2342945 (Source: Chronobiology International)

Psychometric properties of the Turkish reduced morningness and eveningness questionnaire
Chronobiol Int. 2024 Apr 17:1-15. doi: 10.1080/07420528.2024.2339964. Online ahead of print.ABSTRACTThe aim of this study was to examine the psychometric properties of the 5-item Turkish Reduced Morningness-Eveningness Questionnaire (rMEQ) for the first time. The study involved 875 university students in an adaptation and validation study. Participants completed the rMEQ, MEQ, Depression Anxiety Stress Scale-21 (DASS-21), Insomnia Severity Index (ISI), Barratt Impulsiveness Scale Short Form (BIS-SF), and Oxford Happiness Questionnaire Short Form (OHQ-SF). The factor structure, convergent validity, internal consistency, sen...

Promoting adolescent sleep and circadian function: A narrative review on the importance of daylight access in schools
Chronobiol Int. 2024 Apr 14:1-13. doi: 10.1080/07420528.2024.2341156. Online ahead of print.ABSTRACTAdolescent sleep disturbances and circadian delays pose significant challenges to mood and daytime functioning. In this narrative review, we explore the impact of light on sleep and highlight the importance of monitoring and managing light exposure in adolescents throughout the day and night. The benefits of daylight exposure in mitigating sleep and circadian disruptions are well-established; however, interventions targeting access to daylight in adolescents remain understudied and underutilized. The primary aim of this narr...

Chronotype changes after sex hormone use: A prospective cohort study in transgender users of gender-affirming hormones
This study provides the first prospective assessment of sex hormone use and chronotype in transgender persons, showing that GAHT can change chronotype in line with cisgender sex differences. These findings provide a basis for future studies on biological mechanisms and clinical consequences of chronotype changes.PMID:38616311 | DOI:10.1080/07420528.2024.2339989 (Source: Chronobiology International)

Associations between chronotype, diet quality and timing of energy intake in Portuguese children and adolescents: The potential role of summer holidays
Chronobiol Int. 2024 Apr 12:1-11. doi: 10.1080/07420528.2024.2339970. Online ahead of print.ABSTRACTLater chronotypes may be associated with lower diet quality and later timing of energy intake in paediatric age. Period of data collection of these variables may affect these parameters and inter-relationship. We aimed to assess the cross-sectional association of chronotype with a diet quality score (HEI) and caloric midpoint (time of achieving 50% of total daily energy intake), considering summer holidays, using data from the National Food, Nutrition and Physical Activity Survey 2015-2016 for 578 participants (6-14 years of...

Impact of chrono-radiotherapy on the prognosis and treatment-related toxicity in patients with locally advanced nasopharyngeal carcinoma: A multicenter propensity-matched study
Chronobiol Int. 2024 Apr 12:1-11. doi: 10.1080/07420528.2024.2337887. Online ahead of print.ABSTRACTThe timing of radiotherapy (RT) delivery has been reported to affect both cancer survival and treatment toxicity. However, the association among the timing of RT delivery, survival, and toxicity in locally advanced nasopharyngeal carcinoma (LA-NPC) has not been investigated. We retrospectively reviewed patients diagnosed with LA-NPC who received definitive RT at multiple institutions. The median RT delivery daytime was categorized as morning (DAY) and night (NIGHT). Seasonal variations were classified into the darker half of...

Online ahead of print.ABSTRACTSleep and light education (SLE) combined with relaxation is a potential method of addressing sleep and affective problems in older people. 47 participants took part in a four-week sleep education program. SLE was conducted once a week for 60-90 minutes. Participants were instructed on sleep and light hygiene, sleep processes, and practiced relaxation techniques. Participants were wearing actigraphs for 6 weeks, completed daily sleep diaries, and wore blue light-blocking glasses 120 minutes before bedtime. Measures included s...
