¿Como descansa el paciente oncohematológico en el hospital?
(Murcia : Servicio de Publicaciones de la Universidad de Murcia, 2009) Penas Casals, E.; Ruiz Navas, S.; Tormo Gasa, S.
El descanso nocturno es imprescindible para el bienestar físico y psíquico de toda persona y una inadecuada cobertura de esta necesidad influye negativamente en el paciente y altera su calidad de vida. El insomnio definido como ”una deficiencia persistente en la cantidad del sueño que afecta a la normal actividad y bienestar del individuo” es una queja frecuente entre los pacientes hospitalizados; motivo que justifica la necesidad de una atención especial a este problema. Nos planteamos como objetivos identificar qué factores afectan en el descanso nocturno y saber si el personal de enfermería conoce estos factores. Se trata de un estudio descriptivo transversal realizado en las unidades de hematología y oncología durante el mes de marzo de 2008. Para recoger los datos elaboramos una encuesta para los pacientes y otra para el personal de enfermería. El 91% de la muestra respondió que se despertaba durante la noche en el hospital y el 40% lo hace más de tres veces. Los factores que más alteran el descanso del paciente son los factores psicológicos (preocupación por la enfermedad, por la familia y el aburrimiento durante la hospitalización). Como conclusiones destacamos que tanto enfermería como pacientes coinciden en que no se duerme en el hospital. El personal de enfermería demostró tener una buena percepción de las causas principales de insomnio de los pacientes. Ambos han coincidido en cómo los factores psicológicos influyen en el patrón de reposo/sueño. Por ello sería importante que el personal de enfermería dedicara especial atención al manejo de los factores psicológicos a través de distintas técnicas.

Los conocimientos sobre el sueño y los cuidados enfermeros para un buen descanso.
(Murcia : Servicio de Publicaciones de la Universidad de Murcia, 2009) Medina Cordero, A.; Feria Lorenzo, DJ.; Oscoz Muñoa, G.
Los pacientes ingresados en el hospital no duermen bien, unas veces por su patología, y otras por causas ambientales. Identificar los conocimientos de enfermería sobre el sueño, así como la puesta en marcha de actividades que lo mejoren, son aspectos abordados en esta investigación efectuada en el Hospital Infanta Elena de Huelva. Se realizó un estudio observacional descriptivo transversal, utilizándose una encuesta elaborada por el equipo investigador, que se pasó a estos profesionales. Los datos fueron tratados con el programa SPSS para su análisis. Como resultados destacamos que el 75% de las enfermeras/os identifican ambas fases del sueño, pero los pasos por la NREM y REM no lo tienen claro un 55,4%. El 57,4% considera que una persona que se despierta en alguna fase, cuando vuelve a dormir ha de comenzar por la fase I de sueño NREM como si iniciara el reposo, sin embargo el 56,9% afirma que esto no implica que la persona no pueda descansar. Asegurar un número de horas de sueño suficiente es considerado importante para el descanso, sin embargo, por todo lo anterior y además de que no parece tenerse claro que si nos despertamos muchas veces ello hace que la reposición de la energía no pueda completarse, nos lleva a pensar en una falta de conocimientos que sobre el sueño tiene el grupo de enfermeras del estudio.

Correction: Circadian system functional status and sleep in blind subjects with and without conscious light perception
(Frontiers Media, 2026-04-13) Martínez Martínez, David; González Romero, Pedro; Rodríguez Morilla, Beatriz; Bonmatí Carrión, María de los Ángeles; Rol de Lama, María de los Ángeles; Almaida Pagán, Pedro Francisco; Fisiología; Facultades de la UMU::Facultad de Biología
To understand circadian rhythms and sleep in an understudied population, which is particularly prone to suffer chronodisruption (CD), eighteen blind volunteers of 51.5 ± 3.6 years (Mean ± SEM) and 26 volunteers (51.8 ± 1.2) with no visual impairments wore the ambulatory circadian monitoring (ACM) device Kronowise® for seven consecutive days in real-life conditions. Nine of the blind participants declared to have some sort of light perception while the other nine declared to lack conscious light perception. ACM combines measurements of distal skin temperature; motor activity, light exposure and feeding schedules, providing information about lifestyle and the bidirectional crosstalk between internal time and external synchronisers, which is paramount to determine a subject’s CD degree. We found a extraordinarily diverse population in terms of blindness aetiology and thus, in the degree of affectation of the participants visual and circadian systems. Our results pointed to poorer circadian health and sleep in the blind participants, which could be directly related to the impact of disease over circadian photoreception but also to disruption of daily habits. Compared to controls, blind participants showed significantly lower light exposure and physical activity values during the day and higher time of movement during the night. Besides, we analysed feeding schedules in the blind participants for the first time and found that their last meal of the day happened later than in controls, thus blind participants’ night fasting was shorter. Altogether, our results indicated substantial behavioural circadian alterations associated with the disease.

Effects of mindfulness-based cognitive therapy for chronic pain: a multicenter study
(MDPI, 2021-06-29) Pardos Gascón, Estela María; Narambuena, Lucas; Leal Costa, César; Ramos Morcillo, Antonio Jesús; Ruzafa Martínez, María; Hofstadt Román, Carlos Javier van der; Enfermería
The prevalence of chronic pain in Spain is 15%. The objective of this study was to evaluate the efficacy of mindfulness-based cognitive therapy on patients with chronic pain. A quasiexperimental design of repeated measures pre- and post-test (N = 57) was carried out at three hospitals from the province of Alicante. Self-reported assessment measurements of pain intensity, anxiety-depression symptoms, perception of health status, interference of pain on sleep, self-efficacy in pain, acceptance, and mindfulness attitude were included. The T-test indicates significant differences in intensity of present pain, mental quality of life, and depression (medium effect sizes), as well as in self-efficacy: total score, symptom management and pain control (medium effect sizes), sleep disturbances and quantity of sleep (large effect sizes). MBCT is effective in reducing many symptoms in patients with chronic pain, although its maintenance needs to be further investigated.

El estudio del sueño en recién nacidos mediante técnicas de actimetría.
(Murcia : Servicio de Publicaciones de la Universidad de Murcia, 2006) Cubero, J.; Valero, V.; Narciso, D.; Moratinos, A.; Barriga Carrasco, Manuel
El análisis del sueño mediante actimetría es una técnica que supone una alternativa totalmente contrastada a la monitorización del EEG, debido a su fácil manejo, se usa en el caso particular de recién nacidos y en niños de mayor edad. Este sistema de detección del sueño lo forman tres componentes: un piezoacelerómetro de pulsera (Actiwatch®), un lector que nos comunica el Actiwatch con el ordenador personal y el software para el análisis correspondiente, se procesa la actividad recogida, obteniendo determinados parámetros de sueño nocturno a partir del software Sleep Analysis como son: Sueño Asumido, Sueño Real, Eficiencia de Sueño y Latencia de sueño entre otros. Asimismo, utilizando la opción de Nap Analysis conseguimos analizar los posibles episodios de sueño diurno. Por todo ello junto con el fácil mantenimiento y uso, tanto del activimetro como de su software y sin perder por ello fiabilidad, se recomienda su utilización en el estudio del sueño en diferentes estados y estadios de la vida de un individuo.

From improved sleep regularity to reduced sleep complaints and mental health conditions: a population-based interventional study using a smartphone-based virtual agent
(Oxford University Press, 2023-09) Coelho, Julien; Pecune, Florian; Levavasseur, Yannick; Sevin, Etienne de; D'incau, Emmanuel; Patricia Sagaspe, Patricia; Sánchez Ortuño, María Montserrat; Micoulaud Franchi, Jean Arthur; Philip, Pierre; Enfermería
Study Objectives To explore the effect of sleep regularity on sleep complaints and mental health conditions (i.e. insomnia, fatigue, anxiety, and depressive symptoms) in a population-based interventional study using a smartphone-based virtual agent. Methods A populational cohort based on the Kanopée application, which provided interactions with a virtual companion to collect data on sleep and make personalized recommendations to improve sleep over 17 days. A pre-intervention sleep diary and interview were used for cross-sectional analysis (n = 2142), and a post-intervention sleep diary and interview were used for longitudinal analysis (n = 732). The intra-individual mean (IIM) and standard deviation (ISD) of total sleep time (TST) were calculated to measure sleep quantity and sleep regularity. Results The mean age at baseline was 49 years, 65% were female, 72% reported insomnia, 58% fatigue, 36% anxiety, and 17% depressive symptoms. Before the intervention, irregular and short sleep was associated with a higher likelihood of insomnia (Relative risk [RR] = 1.26 [1.21–1.30] for irregular TST and RR = 1.19 [1.15–1.23] for short TST), fatigue, anxiety, and depressive symptoms. After the intervention, the IIM of the TST increased while the ISD of the TST and sleep complaints and mental health conditions decreased. More regular TST was associated with reduced insomnia and depressive symptoms (RR = 1.33 [1.10–1.52] and RR = 1.55 [1.13–1.98], respectively). Conclusions Our results reveal a longitudinal association between sleep regularity and sleep complaints and mental health conditions. Policymakers, health professionals, and the general population should be aware that, beyond its positive effect on sleep health, regular sleep could promote mental health.

Impacto del ambiente hospitalario en el ciclo sueño vigilia y la calidad del sueño de los pacientes
(Universidad de Murcia, 2024-12-10) Padilla Martínez, Julia María; Abad Corpa, Eva; Sánchez Ortuño, María Montserrat; Escuela Internacional de Doctorado
Introducción: El sueño constituye una fase de reposo que está intrínsecamente vinculada con la vigilia, integrando el ciclo circadiano de sueño-vigilia que se repite en un intervalo de 24 horas. La literatura científica señala que el sueño nocturno se encuentra alterado, con frecuencia, en pacientes en situación de hospitalización, debido principalmente a los ruidos constantes del entorno, las actividades llevadas a cabo durante la noche por los profesionales sanitarios, tales como la administración de medicamentos, la toma de constantes vitales, la recogida de muestras etc., el dolor y la incomodidad derivada de ciertas características hosteleras, entre otras. No dormir adecuadamente produce alteraciones durante el periodo de vigilia y tiene repercusiones en otros ritmos y funciones del organismo. Objetivos: Analizar las características del ciclo sueño-vigilia de los pacientes ingresados en hospitales del Servicio Nacional de Salud de manera objetiva y subjetiva; así como la relación existente entre ellas. Explorar la relación entre las características sociodemográficas y de salud de los pacientes, así como las variables derivadas de la propia hospitalización y las actividades de enfermería realizadas durante la noche con la calidad del sueño percibida por los pacientes. Metodología: Estudio observacional, descriptivo y multicéntrico llevado a cabo en 12 hospitales públicos del Servicio Nacional de Salud con un mínimo de 350 camas y que contasen con profesionales que participen en el proyecto SueñOn. Los criterios de inclusión fueron: sujetos mayores de 18 años, duración mínima del proceso de hospitalización de 96h, conscientes y orientados. Criterios de exclusión: personas con discapacidad visual y/o auditiva, puntuación en la escala Glasgow menor a 9, pacientes con cualquier tipo de aislamiento y aquellos incluidos en el plan de cuidados paliativos. Las variables evaluadas fueron obtenidas a través de dos métodos distintos. Por una parte, se usó un cuadernillo de recogida de datos del cual se obtuvieron variables sociodemográficas, de salud y hábitos de vida, referentes a la hospitalización y a la calidad del sueño de los pacientes; así como las distintas actividades llevadas a cabo por el personal de enfermería durante la noche. Por otra parte, se usaron dispositivos de muñeca para la obtención de variables circadianas, diferenciadas entre el periodo de sueño y de vigilia, y la estabilidad de estas. El análisis de los datos se realizó con SPSS 24.0, agrupando los datos descriptivos en categorías. Las variables cualitativas se describieron con frecuencias y porcentajes, y las cuantitativas con medias y desviaciones típicas. Para el análisis inferencial, se utilizó el test chi-cuadrado para asociaciones entre variables cualitativas, el coeficiente de correlación de Spearman para variables cuantitativas y el test t de Student o ANOVA para relaciones entre variables cuantitativas y cualitativas. Se consideró significativo un valor de p<0.05. Conclusiones: • Durante el periodo de hospitalización se observan cambios en los horarios de las variables circadianas relacionadas con el sueño y la vigilia de los pacientes, en comparación con los valores normativos para una población adulta sana. • Durante el periodo de hospitalización, la estabilidad/homogeneidad de las variables circadianas es mayor. • La edad de los pacientes se asoció con un atraso en la variable circadiana TAP_Sueño, que hace referencia a que, a mayor edad, más tarde se localiza la hora central de sueño. • Una mala calidad del sueño durante el periodo de hospitalización se relacionó con tener dolor a lo largo del tiempo de ingreso, compartir habitación la mayor parte del tiempo, la incomodidad de algunas características hosteleras como fueron la cama y la lencería, y la organización de las actividades de enfermería llevadas a cabo en periodo nocturno.

Influencia del uso de redes sociales en el sueño, el rendimiento académico y la actividad física en estudiantes de Secundaria
(Universidad de Murcia, Servicio de Publicaciones, 2024-12-01) Rojí Morcillo, Guillermo
Este estudio analiza el impacto del uso de redes sociales sobre la calidad del sueño, el rendimiento académico y la actividad física en estudiantes de 3º de Educación Secundaria Obligatoria (ESO) en un centro educativo de Caravaca de la Cruz, Murcia. Se evaluaron las relaciones entre el uso de diversas plataformas sociales y los aspectos mencionados. Los resultados revelaron correlaciones negativas moderadas y significativas entre el uso intensivo de Instagram, TikTok y BeReal, y, tanto la calidad del sueño como el rendimiento académico. Los estudiantes que utilizaban estas redes sociales de manera más frecuente mostraron una mayor probabilidad de sufrir problemas de sueño y un rendimiento académico más bajo en comparación con aquellos que limitaban su uso. Las conclusiones subrayan la importancia de tomar medidas para gestionar el uso excesivo de redes sociales en la adolescencia. Esto implica no solo la concienciación sobre sus efectos adversos, sino también el desarrollo de programas educativos y estrategias familiares que fomenten un uso más consciente y equilibrado. Promover hábitos digitales saludables reduciría el impacto negativo en el sueño y el rendimiento académico.

(MDPI, 2023-01-03) Martín Moraleda, Evelyn; Pinilla Quintana, Iván; Romero Blanco, Cristina; Hernández Martínez, Antonio; Jiménez Zazo, Fabio; Dorado Suárez, Alberto; Garcia Coll, Virginia; Cabanillas Cruz, Esther; Herrador Colmenero, Manuel; Queralt, Ana; Castro Lemus, Nuria; Aznar, Susana; Martínez Romero, María Teresa; Actividad Física y Deporte
The aim of this study was to study different ‘healthy profiles’ through the impact of multiple lifestyle behaviours (sleep patterns, screen time and quality diet) on active commuting to school (ACS) in adolescents. Sixteen secondary schools from four Spanish cities were randomly selected. All participants filled in an “Ad-Hoc” questionnaire to measure their mode of commuting and distance from home to school and their lifestyle behaviours. A multivariate logistic regression model was performed to analyse the main predictor variables of ACS. The final sample was 301 adolescents (50.2% girls; mean age ± SD: 14.9 ± 0.48 years). The percentage of ACS was 64.5%. Multiple logistic regressions showed: boys were more active commuters than girls [OR = 2.28 (CI 95%: 1.12–4.64); p = 0.02]; adolescents who lived farther had lower probability to ACS [OR = 0.74 (CI 95%: 0.69–0.80); p < 0.001]; adolescents who met sleep duration recommendations were more likely to ACS [OR = 3.05 (CI 95%: 1.07–8.69); p = 0.04], while with each hour of sleep, the odds of ACS was reduced [OR = 0.51 (CI 95%: 0.30–0.89); p = 0.02]; higher odds were shown to ACS in adolescents who have more adherence to MD [OR = 1.16(CI 95%: 1.00–1.33); p = 0.05]; and habitual breakfast consumption was inversely associated with ACS [OR = 0.41 (CI: 95%: 0.18–0.96); p = 0.04]. ACS was associated with being a boy, living at a shorter distance to school, a daily sleep time ≥ 8 h and presented a higher adherence to MD

Living at the wrong time: effects of unmatching official time in Portugal and western Spain
(MDPI, 2022-07-28) Casado Ramírez, Elvira; Moreno Casbas, María Teresa; Campos Martínez, Manuel; ModulEN Consortium; Madrid, Juan Antonio; Rol de Lama, María de los Ángeles; Bonmatí Carrión, María de los Ángeles; Fisiología
Human circadian rhythmicity is subjected to the internal circadian clock, the sun and social clocks (official time, social/work schedules). The discrepancy among these clocks, as occurs when official time does not match its geographical time zone, may produce circadian disruption. Western Spain (GMT+1/+2) and Portugal (GMT0/+1) share similar longitudes (sun time) but have different official times. This provides a unique opportunity to evaluate the effects of official time on circadian rhythmicity and sleep in elderly and retired populations (with no remunerated duties presumed, although other social commitments may be present) at both locations. Although both populations slept enough for their age (7–8 h), circadian robustness (e.g., interdaily stability, relative amplitude) was greater in Portugal, especially during weekdays, while greater desynchronization (both body temperature vs. motor activity and body temperature vs. light exposure) tended to occur in the Spaniards. Once corrected by GMT0, meals took place later in Spain than in Portugal, especially as the day progresses, and a possible interplay between bed/meal timings and internal desynchronization was found. Our results point to the possible deleterious effect on circadian system robustness when official time is misaligned with its geographical time zone.

Melatonin as a mediator of the gut microbiota–host interaction: implications for health and disease
(MDPI, 2023-12-23) Rol de Lama, María de los Ángeles; Bonmatí Carrión, María de los Ángeles; Fisiología
In recent years, the role played by melatonin on the gut microbiota has gained increasingly greater attention. Additionally, the gut microbiota has been proposed as an alternative source of melatonin, suggesting that this antioxidant indoleamine could act as a sort of messenger between the gut microbiota and the host. This review analyses the available scientific literature about possible mechanisms involved in this mediating role, highlighting its antioxidant effects and influence on this interaction. In addition, we also review the available knowledge on the effects of melatonin on gut microbiota composition, as well as its ability to alleviate dysbiosis related to sleep deprivation or chronodisruptive conditions. The melatonin–gut microbiota relationship has also been discussed in terms of its role in the development of different disorders, from inflammatory or metabolic disorders to psychiatric and neurological conditions, also considering oxidative stress and the reactive oxygen species-scavenging properties of melatonin as the main factors mediating this relationship.

Perceptions and effectiveness of a fully-automated brief behavioral insomnia therapy, delivered by a virtual companion, in older and young adults
(Oxford University Press, 2024-09-24) Sagaspe, Patricia; Sánchez Ortuño, María Montserrat; Dupuy, Lucile; Pecune, Florian; Coelho, Julien; Micoulaud Franch, Jean Arthur; Levavasseur, Yannick; Sevin, Etienne de; Chanteclair, Alex; Philip, Pierre; Salles, Nathalie; Enfermería
Background and Objectives: One of the most common sleep disturbances in older people is insomnia. Cognitive-behavioral therapy is the first-line treatment for this condition in older adults, but in-person treatment is costly and often unavailable. In this study, in a group of older and young subjects, we aimed to compare: (1) their initial perceptions of a fully-automated mobile health intervention to manage insomnia, (2) how these perceptions related to treatment completion, and (3) the effects of the intervention on insomnia severity and related outcomes. Research Design and Methods: A case series study was conducted with a self-selected sample of older (>65 years) and young (18-35 years) adults (n=5,660) who downloaded a free app, available in France, that delivers a brief behavioral intervention for insomniaaided by a virtual companion. The 17-day intervention included sleep hygiene and stimulus control recommendations. Primary outcome was treatment completion (yes/no). At the beginning of the intervention, treatment acceptability and trust in the virtual companion were assessed with two short questionnaires (completion rate: 1,597 users). Insomnia was evaluated with the Insomnia Severity Index. Results: Logistic regression analyses showed that higher credibility and trust in the app’s virtual companion were associated with higher odds of treatment completion, but only in older adults (Trust scores x Age group: OR=1.12, [95%CI=1.01-1.25], p < .05, and Credibility scores x Age group: OR=1.25, [95%CI=1.06-1.47], p < .01). Within the subset of users who completed the intervention (n=289), insomnia remission (χ2=2.72, NS) and insomnia response rates (χ2=2.34, NS) were comparable across both groups. Discussion and Implications: This brief behavioral intervention appears to be efficacious for the self-managementof insomnia symptoms in older adults. The integration of persuasive interaction elements, such as avatars and virtual coaches, in fully-automated interventions could be particularly useful to stimulate older adults’ engagement.

Phase response curve to Light under ambulatory conditions: a pilot study for potential application to caylight saving time transitions
(MDPI, 2022-10-28) Arguelles Prieto, Raquel; Madrid, Juan Antonio; Rol de Lama, María de los Ángeles; Bonmatí Carrión, María de los Ángeles; Fisiología
Several studies have investigated the relationship between daylight saving time (DST) and sleep alterations, psychiatric disorders, cardiovascular events and traffic accidents. However, very few have monitored participants while maintaining their usual lifestyle before and after DST. Considering that DST transitions modify human behavior and, therefore, people’s light exposure patterns, the aim of this study was to investigate the potential effects of DST on circadian variables, considering sleep and, for the first time, the human phase response curve to light. To accomplish this, eight healthy adults (33 ± 11 years old, mean ± SD) were recruited to monitor multivariable circadian markers and light exposure by means of a wearable ambulatory monitoring device: Kronowise®. The following night phase markers were calculated: midpoints of the five consecutive hours of maximum wrist temperature (TM5) and the five consecutive hours of minimum time in movement (TL5), sleep onset and offset, as well as sleep duration and light intensity. TM5 for wrist temperature was set as circadian time 0 h, and the balance between advances and delays considering the phase response curve to light was calculated individually before and after both DST transitions. To assess internal desynchronization, the possible shift in TM5 for wrist temperature and TL5 for time in movement were compared. Our results indicate that the transition to DST seems to force the circadian system to produce a phase advance to adapt to the new time. However, the synchronizing signals provided by natural and personal light exposure are not in line with such an advance, which results in internal desynchronization and the need for longer synchronization times. On the contrary, the transition back to ST, which implies a phase delay, is characterized by a faster adaptation and maintenance of internal synchronization, despite the fact that exposure to natural light would favor a phase advance. Considering the pilot nature of this study, further research is needed with higher sample sizes.

Objectives: The present study examined parental sleep-supporting practices during toddlerhood in relation to temperament across 14 cultures. We hypothesized that passive sleep-supporting techniques (e.g., talking, cuddling), but not active techniques (e.g., walking, doing an activity together), would be associated with less challenging temperament profiles: higher Surgency (SUR) and Effortful Control (EC) and lower Negative Emotionality (NE), with fine-grained dimensions exhibiting relationships consistent with their overarching factors (e.g., parallel passive sleep-supporting approach effects for dimensions of NE). Methods: Caregivers (N = 841) across 14 cultures (M= 61 families per site) reported toddler (between 17 and 40months of age; 52% male) temperament and sleepsupporting activities. Utilizing linear multilevel regression models and groupmean centering procedures, we assessed the role of between- and withincultural variance in sleep-supporting practices in relation to temperament. Results: Both within-and between-culture differences in passive sleepsupporting techniques were associated with temperament attributes, (e.g., lower NE at the between-culture level; higher within-culture EC). For active techniques only within-culture effects were significant (e.g., demonstrating a positive association with NE). Adding sleep-supporting behaviors to the regression models accounted for significantly more between-culture temperament ariance than child age and gender alone. Conclusion: Hypotheses were largely supported. Findings suggest parental sleep practices could be potential targets for interventions to mitigate risk posed by challenging temperament profiles (e.g., reducing active techniques that are associated with greater distress proneness and NE).

Relationship between human pupillary light reflex and circadian system status
(Public Library of Science, 2016-09-16) Hild, Konstanze; Isherwood, Cheryl; Sweeney, Stephen J.; Revell, Victoria L.; Skene, Debra J.; Rol, Maria Ángeles; Madrid, Juan Antonio; Bonmatí Carrión, María de los Ángeles; Anatomía Humana y Psicobiología
Intrinsically photosensitive retinal ganglion cells (ipRGCs), whose photopigment melanopsin has a peak of sensitivity in the short wavelength range of the spectrum, constitute a common light input pathway to the olivary pretectal nucleus (OPN), the pupillary light reflex (PLR) regulatory centre, and to the suprachiasmatic nuclei (SCN), the major pacemaker of the circadian system. Thus, evaluating PLR under short wavelength light (λmax 500 nm) and creating an integrated PLR parameter, as a possible tool to indirectly assess the status of the circadian system, becomes of interest. Nine monochromatic, photon-matched light stimuli (300 s), in 10 nm increments from λmax 420 to 500 nm were administered to 15 healthy young participants (8 females), analyzing: i) the PLR; ii) wrist temperature (WT) and motor activity rhythms (WA), iii) light exposure (L) pattern and iv) diurnal preference (HorneÖstberg), sleep quality (Pittsburgh) and daytime sleepiness (Epworth). Linear correlations between the different PLR parameters and circadian status index obtained from WT, WA and L recordings and scores from questionnaires were calculated. In summary, we found markers of robust circadian rhythms, namely high stability, reduced fragmentation, high amplitude, phase advance and low internal desynchronization, were correlated with a reduced PLR to 460–490 nm wavelengths. Integrated circadian (CSI) and PLR (cp-PLR) parameters are proposed, that also showed an inverse correlation. These results demonstrate, for the first time, the existence of a close relationship between the circadian system robustness and the pupillary reflex response, two non-visual functions primarily under melanopsin-ipRGC input.

Rest-activity circadian rhythms in aged Nothobranchius korthausae. The effects of melatonin
(Elsevier, 2013-03-04) Lucas-Sánchez, Alejandro; Almaida Pagán, Pedro Francisco; Martínez-Nicolás, Antonio; Madrid, Juan Antonio; Mendiola, Pilar; Costa, Jorge de; Fisiología
Adult (48-week-old) and senescent (72-week-old) individually-kept Nothobranchius korthausae were used as experimental subjects to characterise circadian system (CS) function and age-related changes in enescent fish. This species was specifically chosen because it has already shown potential for use as a model system in gerontological studies. The rest-activity rhythm (RAR) in fish can be easily monitored and used to characterise the state of the CS, and it has also been proposed as a reliable model to study sleep-like periods in fish. As they aged, N. korthausae experienced a significant decrease in total daily activity and a progressive impairment of the RAR, accompanied by changes in the regularity, fragmentation and amplitude of the rhythm. The ability of the CS to oscillate autonomouslywhen the twomain synchronizers, photoperiod and feeding time,were absent (continuous darkness and randomfeeding), was also impaired with age, as the capacity to re-synchronise to the light–dark (LD) cycle declined. Melatonin treatment improved the regularity, fragmentation and amplitude of the RAR in senescent fish, and it also improved sleep efficiency. In conclusion,N. korthausae represents a viablemodel for studying the aging of the circadian system and the restorative effect of chronobiotic substances, such as melatonin.

The interplay among sleep patterns, social habits, and environmental cues: insights from the Spanish population and implications for aligning daily rhythms
(Frontiers Media, 2024-10-25) Vicente Martínez, Jesús; Madrid, Juan Antonio; Rol de Lama, María de los Ángeles; Bonmatí Carrión, María de los Ángeles; Fisiología
Introduction: The interplay among sleep patterns, social habits and environmental cues is becoming increasingly more important for public health and wellbeing due to its connection to circadian desynchronization. This paper explores said connections in Spain (which has an official and solar time mismatch), introducing the “Three Times Score” ‒which is based on questions widely used in the field‒ as a complementary tool for exploring the interplay of daily rhythms. Methods: The questionnaire covers sleep-related habits, social time, and environmental time. The study includes 9,947 participants (34.89 ± 12.15 y/o, mean ± SD; 5,561 women) from different Spanish regions. Sleep parameters were obtained for work and free days, as well as a modified version of the sleep-corrected midsleep on free days (MBFbc) and a parameter similar to social jet lag, both derived from bed time rather than sleep time. A number of indexes were computed to compare bed and work-related habits, together with natural light/dark cycle, along with the Three Times Score. Mixed-effect regression analysis was used to test whether the biological, social and environmental factors included in the study significantly predicted the sleep-related parameters: bedtime, wake-up time, time in bed and mid-bedtime. Results and discussion: Temporal differences were found between work and free days, with waking-up occurring 2 h earlier on work days (7:10 ± 0:01) than on free days (9:15 ± 0:01). Bed times were 1 h earlier on work days (23:46 ± 0:01) than on free days (00:45 ± 0:01), whereas time in bed was over 1 h shorter on work (7 h 23 min) versus free (8 h 29 min) days. Strong correlations were found between work starting time and waking-up and bedtimes on workdays. Women went to bed earlier and woke up later, spending more time in bed. Differences in sleep habits were observed between work and free days across all age groups. The group of younger adults (18–30) reported going to bed later than older and younger groups, especially on free days. Adolescents and young adults also woke-up later than other age groups, especially on free days. Social jet lag (relative to bed time) and desynchronization indexes also varied with age, with younger adult participants exhibiting higher levels. Seasonal differences were limited, with minor variations between winter and summer. According to the multiple regression analysis, social (day type, work start time, alarm clock usage), biological (age, gender, in most cases related to sex) and environmental (sunset time) factors significantly contribute to predicting sleep/bed related schedules. This study provides insights into sleep habits in the Spanish population, introducing the Three Times Score as a complementary tool for exploring the interactions between sleep/bed-related habits, natural darkness and work-related schedules. Understanding this interplay is crucial for developing tailored interventions to improve sleep and wellbeing.
