The association between sleep and Alzheimer's disease: a systematic review.

It is estimated that 45% of individuals with cognitive impairment experience sleep disturbances prior to the onset of cognitive symptoms. Assessing sleeping problems and enhancing sleep quality are critical first steps to reduce the risk of cognitive impairment. Objective: To review existing literature based on predefined eligibility criteria to understand the connection between sleep disturbance and Alzheimer's disease. Methods: A thorough and systematic evaluation of numerous studies was carried out to assess one or more of the following epidemiological factors: (1) sleep disorders, (2) cognitive impairment, and (3) risk estimates for cognitive impairment due to sleep. Results: Studies suggest that individuals who experience memory loss may encounter sleep disturbances before noticing other symptoms. Numerous sleep disorders, such as excessive and inadequate sleep duration, poor sleep quality, circadian rhythm abnormalities, insomnia, and obstructive sleep apnea were found to increase the risk of cognitive dysfunction and dementia. Additionally, lower sleep quality and shorter sleep duration have been linked to higher cerebral-ß-amyloid levels. Objective evidence for the development of cognitive impairment is provided by the architecture of sleep stages. Patients experiencing sleep problems may benefit from specific types of sleep medicine as a preventative measure against cognitive decline. Conclusion: Sleep disorders can have adverse effects on cognitive health. The duration and quality of sleep are fundamental factors for maintaining a healthy brain as we age. Proper sleep can aid prevent cognitive impairment, particularly Alzheimer's disease and dementia.

Acredita-se que 45% dos indivíduos com comprometimento cognitivo experimentem distúrbios do sono antes do início dos sintomas cognitivos. Avaliar problemas de sono e melhorar a qualidade do sono são passos críticos iniciais para reduzir o risco de comprometimento cognitivo. Objetivo: Revisar a literatura existente com base em critérios de elegibilidade predefinidos para entender a conexão entre distúrbios do sono e a Doença de Alzheimer. Métodos: Uma avaliação completa e sistemática de vários estudos foi realizada para avaliar um ou mais dos seguintes fatores epidemiológicos: (1) distúrbios do sono, (2) comprometimento cognitivo e (3) estimativas de risco de comprometimento cognitivo decorrente do sono. Resultados: Os estudos sugerem que indivíduos que experimentam perda de memória podem enfrentar distúrbios do sono antes de notarem outros sintomas. Foi constatado que vários distúrbios do sono, como duração excessiva e inadequada do sono, má qualidade do sono, anormalidades no ritmo circadiano, insônia e apneia obstrutiva do sono, podem aumentar o risco de disfunção cognitiva e demência. Além disso, menor qualidade do sono e duração mais curta do sono têm sido associadas a níveis mais altos de ß-amiloide cerebral. Evidências objetivas para o desenvolvimento de comprometimento cognitivo são fornecidas pela arquitetura dos estágios do sono. Pacientes que experimentam problemas de sono podem se beneficiar de tipos específicos de medicamentos para o sono como medida preventiva contra o declínio cognitivo. Conclusão: Os distúrbios do sono podem ter efeitos adversos na saúde cognitiva. A duração e a qualidade do sono são fatores fundamentais para manter um cérebro saudável à medida que envelhecemos. Um sono adequado pode ajudar a prevenir o comprometimento cognitivo, especialmente a Doença de Alzheimer e a demência.

Resilience, sleep quality and sleepiness in Peruvian medical students: a multicenter study.

Background: Resilience can mitigate the negative impact produced by the COVID-19 pandemic. Medical students endure significant academic stress, so adjusting to sudden changes can present greater mental health challenges. The aim is to identify the level and prevalence of resilience and to know what are the educational variables and is sleep quality associated with resilience. Methods: A cross-sectional study was conducted using an online questionnaire. The survey was elaborated in Google Forms and shared through social networks. The outcome was resilience, measured with the Connor Davidson Resilience Scale. Its association was assessed with sleep quality (measured with the Pittsburgh Sleep Quality Index), daytime sleepiness (measured with the Epworth Sleepiness Scale), and selected academic/sociodemographic variables. Generalized linear models were used to identify the association between the variables. Results: Of 1277 participants, 35.7% experienced high resilience. Poor sleep quality and sleepiness were present in 88.4% and 36.0% of students, respectively. High resilience was associated with good sleep quality (PR:1.56; 95%CI: 1.34 - 1.83; p-value<0.001), absent sleepiness (PR:1.59; 95%CI: 1.32-1.91; p-value<0.001), male sex (PR: 1.21; 95%CI: 1.05-1.39; p-value 0.006), working (PR:1.14), having family responsibilities (PR: 1.36; 95%CI: 1.09-1.70; p-value 0.005) and spending more than 6 hours studying (PR: 1.35; 95%CI: 1.17-1.54; p-value<0.001). Conclusion: 4 out of 10 students presented high levels of resilience. The development of resilience depended on multiple individual and sociodemographic factors. These findings are important to support universities in developing resilience-building measures and strategies that can be implemented to mitigate the adverse pandemic event.

Relationship of quality and duration of sleep with arterial hypertension in a Colombian population / Relación de la calidad y la duración del sueño en población colombiana con hipertensión arterial

Introduction. Alterations in the quality and duration of sleep are risk factors for the development of arterial hypertension in Eastern countries. However, in Latin America there are few studies researching this association. Objective. To analyze the association between the quality and duration of sleep and the rate of arterial hypertension in a Colombian population. Materials and methods. An observational, longitudinal, prospective and analytical study nested in the INEFAC population-based cohort, was conducted with participants over 18 years of age from Bucaramanga (Colombia). Sleep quality was assessed using the Pittsburgh Sleep Quality Index. Sleep duration was assessed using standardized questions. Multivariate analysis was performed with logistic regression models adjusted for possible confounding variables. Results. A total of 1,306 non-hypertensive participants with a mean age of 40 ± 12 years were included. In this population, 92.8% had one or more sleep issues. 45.15% slept 6 hours or less and 28.6% slept 8 hours or more. Multivariate analysis showed a higher risk of hypertension in participants with diabetes (OR = 5.27; 95% CI: 2.27-12.26), obesity (OR = 2.81; 95% CI: 1.11-7.13), active smoking (OR = 2.02; 95% CI: 1.01-4.04) and higher socioeconomic level (OR = 4.94; 95% CI: 1.59-15.38 for level 4), but no higher risk was found in participants with poor sleep quality or short sleep duration. Conclusions. No association was found between the duration or quality of sleep and the rate of arterial hypertension in the Colombian population. More studies are required in this population to reach definitive conclusions.

Covid-19 e as condições de saúde de fisioterapeutas baianos atuantes na linha de frente: um estudo observacional / COVID-19 and the health conditions of frontline physical therapists in Bahia: an observational study / COVID-19 y las condiciones de salud de los fisioterapeutas de primera línea de Bahía: un estudio observacional

Durante a pandemia de covid-19, os profissionais de saúde que atuaram na linha de frente viveram um cenário desafiador, com constante risco de infecção pelo SARS-CoV-2, uma demanda de trabalho aumentada e muitas incertezas. O objetivo deste estudo foi analisar as repercussões da covid-19 na saúde de fisioterapeutas baianos atuantes na linha de frente no ambiente hospitalar. Fisioterapeutas baianos participaram deste estudo, respondendo questões referentes aos seus dados sociodemográficos, à qualidade do sono e aos sintomas de ansiedade e depressão, através de um formulário eletrônico (Google Forms). Responderam ao formulário 38 fisioterapeutas residentes em Salvador (BA). A metade deles atua em Unidades de Terapia Intensiva (UTI) e, destes, 65% são trabalhadores do setor privado. Além disso, 68% foram infectados pelo SARS-CoV-2 uma ou mais vezes. O constante medo de infectar seus familiares foi declarado por 77,3% deles e, após o expediente, 36% dos profissionais apresentavam exaustão emocional; 34,2%, estresse psicológico; e 26%, cansaço físico. Os fisioterapeutas baianos relataram que durante a pandemia de covid-19 houve grandes desafios no local de trabalho, como o medo de adoecer e de transmitir a doença e, sobretudo, o medo da morte. O cansaço e o estresse psicológico foram constantes na prática profissional, mas, apesar disso, a maioria dos fisioterapeutas sentiu satisfação por ter atuado de forma tão indispensável em um momento delicado e único.

During COVID-19, health services and professionals who worked on the front line experienced a challenging scenario with a constant risk of infection by SARS-CoV-2, an increased demand for work, and many uncertainties. This study analyzed the repercussions of COVID-19 on the health of Bahian physical therapists working on the hospital front line. Bahian physical therapists participated in this study, answering questions related to their sociodemographic data, sleep quality, and symptoms of anxiety and depression by an electronic form (Google Forms). Overall, 38 physiotherapists living in Salvador (Bahia) answered this form. In total, 50% worked in Intensive Care Units (ICUs); 65%, in the private sector, and 68% suffered infection from SARS-CoV-2 one or more times. This study found that 77.3% of participants reported the constant fear of infecting their family members and 36% showed emotional exhaustion after working hours; 34.2%, psychological stress; and 26%, physical fatigue. Bahian physical therapists reported that COVID-19 brought major confrontations in the workplace, such as the fear of getting sick and transmitting the disease and, above all, death. Fatigue and psychological stress remained constant in the professional practice, but, despite this, most physical therapists felt satisfied for having acted in such an indispensable way in a delicate and unique moment.

Exploring the molecular pathways linking sleep phenotypes and POGZ-associated neurodevelopmental disorder.

Pogo transposable element-derived protein with ZNF domain (POGZ) gene encodes a chromatin regulator and rare variants on this gene have been associated with a broad spectrum of neurodevelopmental disorders, such as White-Sutton syndrome. Patient clinical manifestations frequently include developmental delay, autism spectrum disorder and obesity. Sleep disturbances are also commonly observed in these patients, yet the biological pathways which link sleep traits to the POGZ-associated syndrome remain unclear. We screened for sleep implications among individuals with causative POGZ variants previously described. Sleep disturbances were observed in 52% of patients, and being obese was not observed as a risk factor for sleep problems. Next, we identified genes associated with sleep-associated traits among the POGZ regulatory targets, aiming to uncover the molecular pathways that, when disrupted by POGZ loss of function, contribute to the aetiology of sleep phenotypes in these patients. The intersect between POGZ targets and sleep-related genes was used in a pathway enrichment analysis. Relevant pathways among these overlapping genes are involved in the regulation of circadian rhythm, tau protein binding, ATPase activator activity. This study may represent the beginning for novel functional investigations on shared molecular mechanisms between sleep disturbances and rare developmental syndromes related to POGZ and its regulatory targets.

Risk stratification for frailty, impairment and assessment of sleep disorders in community-dwelling older adults.

BACKGROUND: Frailty is associated with an increased susceptibility to functional decline, impairment, hospitalization, and mortality among the older adults. However, the potential reversibility of frailty lies in identifying modifiable factors that could prevent, mitigate, or interrupt its progression. While there is a suggestion that sleep disorders may increase the risk of frailty and impairment, the risk stratification of this relationship remains inconclusive. OBJECTIVE: Stratify the risk of frailty and impairment and investigate potential connections with sleep quality, excessive daytime sleepiness, and the risk of obstructive sleep apnea in older adults dwelling in the community. METHODS: This was a quantitative cross-sectional investigation. Frailty risk and impairment were stratified using the Frail Non-disabled Questionnaire (for impairment) and the FRAIL Scale (for Frailty). The assessment of excessive daytime sleepiness, sleep quality, and the risk of obstructive sleep apnea involved the employment of the Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index, and the STOP-BANG questionnaire, respectively. RESULTS: A total of 109 older adults living in the urban area (86 %, p = 0.010), females (61 %; p = 0.030), median age 68 (64-75) years, with overweight (36 %, p < 0.010) and self-identified as belonging to other racial or ethnic categories (71 %, p < 0.010). According to the impairment assessment, 32 % of participants were classified as disable (p < 0.01). Conversely, as per the frailty evaluation, 33 % were pre-frail and 25 % were identified as frail. Additionally, a substantial proportion experienced poor sleep quality (80 %, p = 0.010), exhibited a moderate risk of obstructive sleep apnea (49 %, p < 0.010), and showed no signs of excessive daytime sleepiness (62 %, p < 0.010). There was a modest correlation between frailty and impairment with poor sleep quality (rho = 0.39; p < 0.001) and the risk of obstructive sleep apnea (rho = 0.26; p = 0.000). However, the was no significant relationship was observed between frailty and impairment and excessive daytime sleepiness (rho = 0.04; p = 0.660). Similarly, a modest correlation was observed between sleep quality (rho = 0.33; p < 0.001), the risk of obstructive sleep apnea (rho = 0.27; p = 0.001), and frailty. Conversely, no correlation was found with excessive daytime sleepiness (rho = 0.05; p = 0.590). Also, the poor sleep quality and the risk of obstructive sleep apnea explain 14 % of the risk of frailty in the population of community-dwelling older adults (r2 = 0.14; p = 0.04). CONCLUSION: This study reveals a modest risk of frailty and impairment with sleep quality and the risk of obstructive sleep apnea, but not with excessive daytime sleepiness in community-dwelling older adults.

The Sleep Patterns of Children and Adolescents with Chronic Conditions and Their Families: An Integrative Literature Review.

Sleep is of vital necessity for health, and it has a restorative and protective function for children and adolescents with chronic conditions and their families. The purpose of this study was to identify the scientific production on sleep patterns in children and adolescents with chronic conditions and their families. This integrative review was conducted between March and June 2022 using the databases of MEDLINE, Web of Science, CINAHL and PsycINFO. The articles included were original papers published between January 2007 and mid-2022. Excluded were review studies that did not evaluate sleep and whose participants did not have chronic conditions or were not children, adolescents and/or their families. The searches returned 814 abstracts. After exclusions, 47 studies were selected to be read in full; of these, 29 were selected and were grouped empirically into four categories: major alterations in the sleep patterns of children and adolescents with chronic conditions; the relationship between sleep disorders and symptoms in children and adolescents with chronic conditions; the impaired sleep patterns of families of children and adolescents with chronic conditions; and sleep alterations and their relationship with other problems in families of children and adolescents with chronic conditions. All studies showed sleep pattern impairment in children and adolescents with chronic conditions as well as their families.

Sleep disorders, anxiety and obesity associated with untreated dental caries in children eight to ten years of age.

OBJECTIVE: To evaluate the presence of sleep disorders, obesity and anxiety associated with cavitated carious lesions in children aged 8 to 10 years. MATERIALS AND METHODS: A cross-sectional study was carried out in the Northeast of Brazil. The sample was comprised of 793 schoolchildren randomly selected from public and private schools. Calibrated examiners (Kappa >0.80) performed the clinical examination of dental caries using the International Caries Detection and Assessment System and applied the Revised Children's Manifest Anxiety Scale and the Sleep Disturbance Scale for Children questionnaires. The anthropometric variables evaluated were weight and height. Negative binomial regressions (α ≤ 0.05) were performed. A Directed Acyclic Graph was prepared using DAGitty software (version 3.0), to select the co-variables for the statistical fits. RESULTS: The prevalence of tooth decay was 52.8%. The mean number of tooth surfaces with cavitated caries was 2.2(2.8), 58.9% of the schoolchildren had some type of sleep disorder, while 20.2% were anxious and 29.1% were obese. Sleep disturbance (RR = 1.38; 95% CI: 1.05-1.83), general anxiety (RR = 1.71; 95% CI: 1.32-2.21), obesity (RR = 1.48; 95% CI: 1.17-1.86) were associated with dental caries in the final model. CONCLUSION: The presence of carious lesions was higher in children with sleep disorders, anxiety, obesity, and those who experienced dry mouth.

The relationship between burden and caregiver's sleep disturbances in dementia: a systematic review.

Caregivers of people living with dementia (PLwD) have a high burden degree that leads to health issues, including sleep. Objective: This study aimed to analyze the impacts of the caregiving burden on caregiver's sleep disturbances. Methods: This systematic review involved a qualitative analysis of publications on Web of Science and Pubmed/Medline databases published between February 2018 and August 2022. Results: A total of 27 studies were identified and analyzed. Caregiver's sleep presents impairments in sleep latency, sleep fragmentation, sleep duration, subjective sleep quality, daytime dysfunction, and insomnia. Caregiver's distress and depressive symptoms have a dual relationship with sleep problems. Conclusion: Sleep disturbances presented by caregivers are correlated with higher burden levels and lead to more vulnerability to psychiatric symptoms and health issues.

Objetivo: Este estudo teve o objetivo de analisar o impacto da sobrecarga nas alterações do sono do cuidador. Métodos: Esta revisão sistemática envolveu a análise de resultados quantitativos e qualitativos de publicações das bases de dados Web of Science e PubMed/ Medical Literature Analysis and Retrieval System Online (Medline) publicadas entre fevereiro de 2018 e agosto de 2022. Resultados: O total de 27 estudos foi identificado e analisado. Cuidadores apresentam prejuízos na latência, fragmentação, duração e qualidade subjetiva do sono, disfunção diurna e insônia. O estresse e sintomas depressivos apresentados pelo cuidador possuem com o sono uma relação bidirecional. Conclusão: Os distúrbios do sono apresentados pelos cuidadores estão correlacionados com o alto nível de sobrecarga e geram maior vulnerabilidade para sintomas psiquiátricos e problemas de saúde.

REM sleep behavior disorder: update on diagnosis and management / Transtorno comportamental do sono REM: atualização no diagnóstico e manejo

Abstract REM sleep behavior disorder (RBD) is characterized by a loss of atonia of skeletal muscles during REM sleep, associated with acting out behaviors during dreams. Knowledge of this pathology is important to predict neurodegenerative diseases since there is a strong association of RBD with diseases caused by the deposition of alpha-synuclein in neurons (synucleinopathies), such as Parkinson's disease (PD), multiple system atrophy (MSA), and dementia with Lewy bodies (DLB). Proper diagnosis of this condition will enable the use of future neuroprotective strategies before motor and cognitive symptoms. Diagnostic assessment should begin with a detailed clinical history with the patient and bed partner or roommate and the examination of any recorded home videos. Polysomnography (PSG) is necessary to verify the loss of sleep atonia and, when documented, the behaviors during sleep. Technical recommendations for PSG acquisition and analysis are defined in the AASM Manual for the scoring of sleep and associated events, and the PSG report should describe the percentage of REM sleep epochs that meet the criteria for RWA (REM without atonia) to better distinguish patients with and without RBD. Additionally, PSG helps rule out conditions that may mimic RBD, such as obstructive sleep apnea, non-REM sleep parasomnias, nocturnal epileptic seizures, periodic limb movements, and psychiatric disorders. Treatment of RBD involves guidance on protecting the environment and avoiding injuries to the patient and bed partner/roommate. Use of medications are also reviewed in the article. The development of neuroprotective medications will be crucial for future RBD therapy.

Resumo O transtorno comportamental do sono REM (TCSREM) é caracterizado por uma perda de atonia dos músculos esqueléticos durante o sono REM, associada a comportamentos de atuação durante os sonhos. O conhecimento desse transtorno é importante como preditor de doenças neurodegenerativas, uma vez que existe uma forte associação de TCSREM com doenças causadas pela deposição de alfa-sinucleína nos neurônios, como a doença de Parkinson (DP), atrofia de múltiplos sistemas (MSA) e demência com corpos de Lewy (DLB). O diagnóstico adequado dessa condição permitirá o uso de futuras estratégias neuroprotetoras antes do aparecimento dos sintomas motores e cognitivos. A avaliação diagnóstica deve começar com uma história clínica detalhada com o paciente e acompanhante, além de exame de vídeos. A polissonografia (PSG) é necessária para verificar a perda da atonia do sono e, quando documentados, os comportamentos durante o sono. As recomendações técnicas para aquisição e análise de PSG são definidas no Manual da AASM (Scoring of sleep and associated events) e o relatório de PSG deve descrever a porcentagem de períodos de sono REM que atendem aos critérios para REM sem atonia. Além disso, a PSG ajuda a descartar condições que podem mimetizar o TCSREM, como apneia obstrutiva do sono, parassonias do sono não REM, crises epilépticas noturnas, movimentos periódicos dos membros e transtornos psiquiátricos. O tratamento do TCSREM envolve orientações sobre adaptações do ambiente para evitar lesões ao paciente e ao colega de quarto. Medicamentos utilizados são revistos no artigo, assim como o crucial desenvolvimento de medicamentos neuroprotetores.

Calidad del sueño y depresión perinatal en gestantes atendidas en un centro de atención primaria en Lima, Perú / Sleep Quality and Perinatal Depression in Pregnant Women Treated in a Primary Care Centre in Lima, Peru

RESUMEN Objetivo: Evaluar la asociación entre la calidad del sueño y la depresión perinatal en gestantes que cursan entre las semanas de gestación 12 y 36 en un centro materno-infantil de Lima. Métodos: Estudio transversal analítico en gestantes atendidas en un centro de atención primaria entre agosto y diciembre de 2019. Los datos se recogieron mediante una encuesta auto aplicada. Se empleó el Índice de calidad del sueño de Pittsburgh (PSQI) para la evaluación de la calidad de sueño. La depresión perinatal se evaluó con la Escala de Depresión Posnatal de Edimburgo (EPDS). Para el análisis multivariado, se utilizó la regresión de Poisson con varianzas robustas a fin de calcular las razones de prevalencia brutas y ajustadas y sus respectivos intervalos de confianza. Resultados: Se incluyó a 200 participantes. La mediana de edad [intervalo intercuartílico] fue 26 [22-32] arios y 111 gestaciones (55,5%) fueron no planificadas. El 52% tenía mala calidad del sueño, y el riesgo de depresión perinatal fue del 31,5%. La mala calidad del sueño se asoció con una frecuencia significativamente mayor de depresión perinatal (con mala calidad de sueño que merece atención médica, RPa = 4,8; con mala calidad de sueño que merece atención y tratamiento médico, RPa = 6,6). Conclusiones: Existe una posible asociación entre la mala calidad del sueño y la depresión perinatal en gestantes entre las semanas 12 y 36 de gestación. Se debe promover investigaciones operativas a fin de evaluar si intervenciones para mejorar la calidad del sueño podrían tener un impacto positivo en la reducción de la depresión perinatal.

ABSTRACT Objective: The aim is to evaluate the association between sleep quality and perinatal depression in pregnant women between the 12th week of gestation and the 36th week of gestation in a maternity and child centre in Lima. Methods: Analytical cross-sectional study in pregnant women cared for in a primary care centre between August and December 2019. The data were collected through a self- administered survey. The Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep quality. The evaluation of perinatal depression was performed with the Edinburgh Postnatal Depression Scale (EPDS). For the multivariate analysis, Poisson regression with robust variances was used to calculate the crude and adjusted prevalence ratios and their respective confidence intervals Results: The sample was composed of 200 participants. The median [IQR] age was 26 [22-32] years, and 111 (55.5%) pregnancies were unplanned. 52% presented a poor quality of sleep and the risk of perinatal depression was 31.5%. Poor quality of sleep was associated with a significantly higher frequency of perinatal depression (aPR = 4.8 for those with poor quality of sleep warranting medical attention, and aPR = 6.6 for those with poor quality of sleep warranting medical attention and treatment). Conclusions: There is a possible association between poor sleep quality and perinatal depression in pregnant women between weeks 12 and 36 of gestation. Operational research should be promoted to assess whether interventions to improve sleep quality could have a positive impact on reducing perinatal depression.

Sleep assessment in adults with Down syndrome: correlation between functionality and polysomnographic findings / Avaliação do sono de adultos com síndrome de Down: correlações entre funcionalidade e achados polissonográficos

Abstract Background Sleep disorders have a negative impact on health, being associated with neurocognitive problems, cardiovascular diseases and obesity, influencing children's development and learning. Objective To assess the sleep pattern of people with Down syndrome (DS) and correlate changes with functionality and behavior. Methods A cross-sectional study was conducted to evaluate the sleep pattern in adults with DS > 18 years old. Twenty-two participants were assessed using the Pittsburgh Sleep Quality Index, the Functional Independence Measure and the Strengths and Difficulties Questionnaire, and the 11 who presented indications of disorders by the screening questionnaires were referred to polysomnography. Statistical tests were performed using a significance level of 5%, including sample normality tests and correlation tests (sleep and functionality). Results Impairment in sleep architecture was found due to an increase in the rate of awakenings in 100% of the participants, a decrease in the number of slow waves, and a high prevalence of sleep disordered breathing (SDB), with higher averages in the Apnea and Hypopnea Index (AHI) in the group. There was a negative correlation between sleep quality and global functionality (p= 0.011) and the motor (p= 0.074), cognitive (p= 0.010), and personal care (p= 0.072) dimensions in the group. Global and hyperactivity behavior changes were related to worse sleep quality (p= 0.072; p= 0.015, respectively). Conclusion There is an impairment in the sleep quality of adults with DS, with an increase in the rate of awakenings, a decrease in the number of slow waves, and a high prevalence of SDB affecting this population in the functional and behavioral aspects.

Morningness/eveningness in gestational diabetes mellitus: clinical characteristics and maternal-neonatal outcomes

ABSTRACT Objective: This study aims to evaluate the impact of morning-evening preference in pregnancy outcomes in gestational diabetes mellitus (GDM). Materials and methods: This is a prospective cohort study of 2nd-3rd trimester GDM outpatient care in Fortaleza, Brazil (2018-2020). Eveningness was defined by the Horne-Östberg Morningness-Eveningness-Questionnaire (MEQ ≤ 41). Furthermore, we obtained a 7-day actigraphic register. Subjective sleep quality, daytime somnolence, insomnia, fatigue and depressive symptoms were also evaluated. Associations with pregnancy outcomes were investigated. Results: Among 305 patients with GDM, evening preference was found in 21 (6.9%). Patients with evening preference had worse sleep quality (p < 0.01), greater severity of insomnia (p < 0.005), fatigue (p < 0.005) and depressive symptoms (<0.009). Evening chronotype was associated with preeclampsia [p = 0.01; OR = 0.27; CI 0.09-0.79] and a greater need for admission to a neonatal intensive care unit (NICU) [p = 0.02; OR = 0.23; CI .0.06-0.80]. A lower MEQ score confirmed an association with preeclampsia [p = 0.002; OR = 0.94; CI 0.90-0.97] and this was maintained after controlling for age, arterial hypertension, sleep quality, fatigue and depressive symptoms [p < 005; OR = 0.91; CI 0.87-0.95]. Conclusion: In GDM, patients with evening preference had worse sleep quality, more insomnia, fatigue, and depressive symptoms. Furthermore, eveningness was independently associated with preeclampsia. These results indicate the important role of eveningness in adverse pregnancy outcomes.
