Sleep Quality in CrossFit: A Cross-Sectional Study.

Objective Based on the relationship between sleep and sports performance, the present study aimed to evaluate sleep quality and excessive daytime sleepiness among adult CrossFit (CrossFit, LLC, Santa Cruz, CA, USA) practitioners and to verify possible associations with intestinal health. Methods This cross-sectional study involved males and females aged ≥ 18 years who had been regularly practicing CrossFit for at least 3 months. This survey used an online questionnaire addressing demographic and socioeconomic data, disease history, dietary characteristics, and questions regarding CrossFit. To assess intestinal health, the ROME IV Consensus Criteria and Bristol Scale were used. The Pittsburgh International Sleep Quality Index (PSQI-BR) and Epworth Sleepiness Scale were used to assess sleep quality. Results A total of 1,090 people (73.3% females) with a mean age of 31.2 ± 7.5 years were included. Considering the diagnosis of constipation, 36.9% of the patients were classified as constipated, especially females when compared with males ( p < 0.001). On the sleepiness scale, 22.4% of the volunteers showed excessive daytime sleepiness, which was also observed more frequently among females ( p = 0.013). In the PSQI-BR, 47.4% of participants were classified as having poor sleep quality (poor sleepers). The overall PSQI-BR score was 5.81 ± 2.85, with no difference between males and females ( p = 0.360). There was a positive correlation between the PSQI-BR global score and a diagnosis of constipation and excessive daytime sleepiness. There was a negative correlation between the stool type on the Bristol scale and the PSQI-BR global score. Conclusion The present study demonstrated that sleep quality was poor among CrossFit users, especially females, which can compromise their training performance.

[Excessive daytime sleepiness in older adults of a municipal physical activity program] / Somnolencia diurna excesiva en adultos mayores de un programa municipal de actividad física.

Introduction: Physical exercise has been shown to have a favorable impact on the health of the individual. Its combination with other healthy lifestyles can positively impact various areas, including sleep quality. Objective: To determine the frequency of excessive daytime sleepiness in older adults of a municipal physical activity program in Santiago de Cali, Colombia. Methodology: Cross-sectional study that included 605 older adults from a community program of the Secretary of Recreation and Sports of the City of Cali, Colombia, during October 2018 and June 2019. To determine the presence of excessive daytime sleepiness, the Epworth Sleepiness Scale was used. Results: 81.5% of the population was female with a mean age of 73±8 years. The prevalence of excessive daytime sleepiness was 10.5%. Significant differences were only found in the frequency of excessive daytime sleepiness by socioeconomic stratum, being more common in the low socioeconomic stratum (13% vs 4% P=0.03). Conclusion: Excessive daytime sleepiness is a phenomenon that affects older adults; however, its frequency may be lower in those who are physically active.

Impacto econômico da implementação de políticas públicas para distúrbios de sono no Brasil: uma revisão integrativa / Economic impact of the implementation of public policies for sleep disorders in Brazil: an integrative review

Objetivo: Identificar estudos sobre políticas públicas, ações de saúde e análises econômicas relacionados aos distúrbios de sono no Brasil e discutir os seus resultados para o sistema de saúde, gestores de políticas públicas e a sociedade. Métodos: Revisão integrativa da literatura nas bases de dados Lilacs (via BVS), SciELO e PubMed (via Medline), incluindo estudos publicados nos idiomas português, inglês e espanhol, entre os anos de 1960-2023; foram excluídos estudos que não apresentaram a perspectiva brasileira ou aqueles cuja versão integral não estava disponível (seja gratuitamente ou na versão paga). Resultados: A busca retornou 536 resultados, dos quais apenas dois atendiam aos critérios de inclusão e mais cinco trabalhos foram incluídos manualmente, após consulta com especialistas de sono (todos abordaram apneia obstrutiva do sono, sendo: um relato sobre alteração na legislação de trânsito focada em prevenção de acidentes por sonolência excessiva; uma revisão de escopo sobre análises de custo-efetividade do tratamento da doença com uso de CPAP; dois relatos sobre linha de cuidado em um município e outros três em Secretarias Estaduais de Saúde). Conclusões: A revisão integrativa encontrou poucas evidências acerca do tema e aponta para a necessidade de futuros estudos que visem a suprir essa lacuna científica e de que seja necessário o desenvolvimento de futura linha de cuidado que amplie o acesso ao tratamento de doenças do sono no Sistema Único de Saúde.

Objective: To identify studies on public policies, health actions, and economic analyses related to sleep disorders in Brazil and discuss their results for public policy managers and society. Methods: Integrative literature review using Lilacs (via BVS), SciELO, and PubMed (via Medline) databases, including studies published in Portuguese, English, and Spanish languages, between years of 1960-2023; studies that did not present the Brazilian perspective or whose full version was not available were excluded (free or paid version). Results: The search returned 536 results, of which only two met the inclusion criteria, and five more studies were included manually after consulting sleep experts (all addressing obstructive sleep apnea, namely: a report on changes in traffic legislation focused on preventing accidents caused by excessive sleepiness; a scoping review on cost-effectiveness analysis of CPAP for sleep apnea treatment; two reports on care lines in one municipality and another three in State Secretariats). Conclusions: The integrative review found few evidences on the topic and points to the need for future studies aimed at filling this scientific gap and the development of a care line that expands access to sleep disorder treatment in Brazilian Public Health System.

Effect of Tinnitus on Sleep Quality and Insomnia

Abstract Introduction Tinnitus is a conscious perception of a sound resulting from abnormal activity within the nervous system. A relevant percentage of tinnitus patients report symptoms severe enough to significantly affect quality of life, including sleep disorders. Objectives To analyze the sleep quality, insomnia, daytime sleepiness, and risk of obstructive sleep apnea (OSA) in participants with tinnitus. Methods The sample comprised 18 adults and older adults aged between 18 and 85 years old (mean age = 58.7 ± 17.5 years old), females and males, with complaint of continuous tinnitus for > 1 month. The instruments used were the Tinnitus Handicap Inventory (THI) questionnaire, the Insomnia Severity Index, the Pittsburgh Sleep Quality Index, the Epworth Sleepiness Scale, and the STOP-Bang questionnaire. Results By means of the THI questionnaire, the tinnitus severity degree reported by most participants was mild (27.8%) and moderate (27.8%), having a positive (r = 0.582) and significant (0.011) correlation to sleep quality, measured by means of the Pittsburgh questionnaire. There was a positive correlation between the Insomnia Severity Index and tinnitus handicap (r = 0.499; p = 0.035). A total of 72.2% of the participants self-assessed their sleep quality as poor, in addition to moderate insomnia (27.8%), although there is low risk of OSA (66.7%), without complaints of excessive daytime sleepiness (72.2%). Conclusion Subjects with tinnitus complaint self-rated their sleep quality as poor. Moreover, the higher the reported tinnitus handicap, the greater the symptoms of insomnia. There was no influence of tinnitus in relation to daytime sleepiness and no relationship between the severity of tinnitus and the risk of OSA.

The Impact of Nonmotor Symptoms on Health-Related Quality of Life in Parkinson's Disease: A Network Analysis Approach.

Nonmotor symptoms negatively affect health-related quality of life (HRQoL) in patients with Parkinson's disease (PD). However, it is unknown which nonmotor symptoms are most commonly associated with HRQoL. Considering the complex interacting network of various nonmotor symptoms and HRQoL, this study aimed to reveal the network structure, explained HRQoL variance, and identify the nonmotor symptoms that primarily affect HRQoL. We included 689 patients with PD from the Cohort of Patients with Parkinson's Disease in Spain (COPPADIS) study who were rated on the Nonmotor Symptoms Scale in Parkinson's disease (NMSS) and the Parkinson´s Disease Questionnaire 39 (PDQ-39) at baseline. Network analyses were performed for the 30 items of the NMSS and both the PDQ-39 summary index and eight subscales. The nodewise predictability, edge weights, strength centrality, and bridge strength were determined. In PD, nonmotor symptoms are closely associated with the mobility, emotional well-being, cognition, and bodily discomfort subscales of the PDQ-39. The most influential nonmotor symptoms were found to be fatigue, feeling sad, hyperhidrosis, impaired concentration, and daytime sleepiness. Further research is needed to confirm whether influencing these non-motor symptoms can improve HRQoL.

Clinical applications of artificial intelligence in sleep medicine: a sleep clinician's perspective.

BACKGROUND: The past few years have seen a rapid emergence of artificial intelligence (AI)-enabled technology in the field of sleep medicine. AI refers to the capability of computer systems to perform tasks conventionally considered to require human intelligence, such as speech recognition, decision-making, and visual recognition of patterns and objects. The practice of sleep tracking and measuring physiological signals in sleep is widely practiced. Therefore, sleep monitoring in both the laboratory and ambulatory environments results in the accrual of massive amounts of data that uniquely positions the field of sleep medicine to gain from AI. METHOD: The purpose of this article is to provide a concise overview of relevant terminology, definitions, and use cases of AI in sleep medicine. This was supplemented by a thorough review of relevant published literature. RESULTS: Artificial intelligence has several applications in sleep medicine including sleep and respiratory event scoring in the sleep laboratory, diagnosing and managing sleep disorders, and population health. While still in its nascent stage, there are several challenges which preclude AI's generalizability and wide-reaching clinical applications. Overcoming these challenges will help integrate AI seamlessly within sleep medicine and augment clinical practice. CONCLUSION: Artificial intelligence is a powerful tool in healthcare that may improve patient care, enhance diagnostic abilities, and augment the management of sleep disorders. However, there is a need to regulate and standardize existing machine learning algorithms prior to its inclusion in the sleep clinic.

Retrospective cohort study of hypersomnias of central origin from two Australian tertiary sleep disorders services.

BACKGROUND: Hypersomnias of central origin (HOCO) are diverse in origin and symptomatology and remain poorly described in an Australian population. We hypothesised that the rate of human leukocyte antigen (HLA) DQB1*0602 positivity in the Australian cohort would be comparable to international registries. AIMS: The current study aims to evaluate epidemiological and clinical characteristics of Australian patients with HOCO, including prevalence of HLA DQB1*0602 positivity, the most specific HLA marker associated with narcolepsy. METHODS: This is a retrospective study. Patients ≥ 16 years of age presenting with symptoms of hypersomnolence who attended one of two Australian sleep centres (New South Wales and Queensland) in the preceding 24 months and had undergone both HLA serology and multiple sleep latency tests (MSLTs) were included. Main outcome measures included demographics, HLA DQB1*0602 positivity, MSLT, and clinical parameters (presence of auxiliary narcolepsy symptoms, laboratory tests, relevant prescribed medications). RESULTS: Eighty-eight patients were included. HLA DQB1*0602 positivity was highest in those with type 1 narcolepsy (NT1) (95.7%) and lowest in those without a classifiable disorder (9.1%). Mean sleep latency was lowest and number of sleep-onset rapid eye movement periods (SOREMPs) highest in the NT1 group. Comorbid disorders, particularly depression and overweight/obesity, were prevalent in all cohorts. Across all diagnostic groups, dexamphetamine was the most commonly prescribed agent for excessive daytime sleepiness. CONCLUSIONS: Patients with HOCO assessed in two specialised Australian clinics demonstrate comparable clinical characteristics to other published cohorts internationally; however, available pharmacological agents in Australia do not reflect international standards of care.

Sleepiness in adults: An umbrella review of a complex construct.

Sleepiness involves many dimensions that require investigation. Since sleepiness is often defined operationally, we exhaustively inventoried all the assessment tools designed to measure it in an umbrella review, without any preconceptions, i.e. a review of reviews. We included all reviews and systematic reviews related to sleepiness assessment tools published up to March 2021. Three investigators independently assessed the eligibility of studies for inclusion and identified 36 relevant reviews. In total, 99 tools were identified and classified into 8 categories. We classified them depending on their category, their publication year and the number of mentions in the 36 included reviews. The 6 most frequently cited were the Epworth sleepiness scale, the multiple sleep latency test, the maintenance of wakefulness test, the Stanford sleepiness scale, the Karolinska sleepiness scale, and the psychomotor vigilance task. Despite the limitation that we may have missed some recently developed tools, this historical perspective on sleepiness measurement is a first step toward a better delineation of the different dimensions underlying the constructs of sleepiness, and will serve as a basis for further discussion in the clinical and research sleep community.

Interaction between apolipoprotein E genotypes, excessive daytime sleepiness, and cognitive function in obstructive sleep apnea patients / Interação entre genótipos da apolipoproteína E, sonolência excessiva diurna e função cognitiva em pacientes com apneia obstrutiva do sono

Abstract Background Some studies show an association between the apolipoprotein E ε4 allele (ApoEε4) and obstructive sleep apnea syndrome (OSAS), and other studies, an association between ApoEε4 and excessive daytime sleepiness (EDS), but there are no data in the literature on the interaction between EDS, cognitive function, and ApoEε4 in patients with OSA. Objective To examine the cognitive function of adults with and without EDS and with and without ApoEε4. Methods A total of 21 male and female patients aged between 33 and 79 years, underwent a clinical interview, ApoE genotyping, neuropsychological evaluation, polysomnography, and the application of the Epworth Sleepiness Scale. Results Excessive daytime sleepiness was associated with lower intelligence quotient (IQ; total performance) and worse immediate visual memory, regardless of the ApoE genotype. Patients carrying the ApoEε3/ε4 genotype had a worse performance in divided attention, constructional praxis, perceptual organization, and cognitive flexibility. A combination of the ε4 allele and EDS potentiates the negative effect on cognition, except for immediate visual memory. In this case, patients had a worse performance in terms of processing speed, selective attention, and visuomotor coordination. Conclusions Excessive daytime sleepiness and the ApoEε3/ε4 genotype are associated with worse cognitive performance in OSA patients. The combination of EDS and ε4 allele potentiates cognitive impairment.

Resumo Antecedentes Alguns estudos mostram uma associação entre o alelo ε4 da apolipoproteina E (ApoEε4) e a síndrome da apneia obstrutiva do sono (SAOS), e outros, entre ApoEε4 e a sonolência excessiva diurna (SED), mas não há dados na literatura sobre a interação entre SED, função cognitiva e ApoEε4 em pacientes com SAOS. Objetivo Avaliar a função cognitiva em adultos com SAOS com e sem SED e com e sem ApoEε4. Métodos Ao todo, 21 pacientes, de 33 a 79 anos, homens e mulheres, foram avaliados clinicamente, e submetidos a genotipagem ApoE, avaliação neuropsicológica, polissonografia, e aplicação da Escala de Sonolência de Epworth. Resultados A SED esteve associada com menor quociente de inteligência (QI; desempenho geral) e pior memória visual imediata, independentemente do genótipo ApoE. Pacientes com genótipo ApoEε3/ε4 apresentaram pior desempenho na atenção dividida, praxe construcional, organização perceptiva e flexibilidade cognitiva. A combinação do alelo ε4 com a SED potencializa esse efeito deletério na cognição, exceto na memória visual imediata. Nesse caso, os pacientes tiveram uma menor velocidade de processamento cognitivo, e piores atenção seletiva e coordenação visiomotora. Conclusões A SED e o genótipo ApoEε3/ε4 estão associados a um pior desempenho cognitivo em pacientes com SAOS. A combinação de SED e do alelo ε4 potencializa esse efeito.

Objective: To determine the variation of the Quality of Life in patients with mild to moderate Obstructive Sleep Apnea Hypopnea Syndrome, after treatment with the Mandibular Advancement Device at an altitude of 3259 masl. Methods: Prospective, quasi-experimental study. Subjects with respiratory disturbance index (RDI) between 5 and 30 / hour (measured with respiratory polygraphy), without previous treatments, with conditions for the use of MAD were included. The quality of life was assessed with the FOSQ (questionnaire of functional sleep results) before and after 45 days of treatment with MAD. Results: 26 completed the study (20 males). The mean (SD) of the age was 43 (9.6) years, BMI was 29 (8.6) kg / m2, and the RDI was 19 (7.6) / hour. After 45 day, significant changes were observed, with respect to the baseline values, in the FOSQ score (total calculation, general productivity, social outcome, activity level, vigilance and intimate relationships/sexual activity, p <0.001). The mean RDI decreased from 19 (7.6) to 7 (3.8) (p <0.001), the minimum desaturation of O2 increased from 77 (5.2) to 83 (3.9) (p <0.001), the T90 decreased from 73 (15.4) to 31 (16.6) (p <0.001) y Epworth's score decreased from 11.2 (4.6) to 6.4 (3.5) (p <0.001). Conclusions : In patients with mild-moderate OSA, treatment with MAD produces significant improvement in their quality of life, reduces the level of disease expressed in decreased RDI, improves oxygenation level and reduces daytime sleepiness expressed in decreased Epworth score.

The Number of Monthly Night Shift Days and Depression Were Associated with an Increased Risk of Excessive Daytime Sleepiness in Emergency Physicians in South Korea.

This study aimed to report the prevalence and identify the factors associated with excessive daytime sleepiness (EDS) among emergency physicians in South Korea. We analyzed the Korean Emergency Physicians Survey data from 15 January to 26 February 2021. EDS was evaluated using the Epworth sleepiness scale, and a score of 11 or more indicated the presence of EDS. We conducted univariable and multivariable logistic regression analyses to verify the associated factors. A total of 1307 participants responded to the survey, and the response rate was 61.3%. Nine hundred fifty-four participants were included in the study. Two hundred ninety-three participants were classified as the EDS group, and six hundred sixty-one were classified as the non-EDS group. The prevalence of EDS was 30.7% (95% confidence interval (CI), 27.8-33.6%). Monthly night-shift days (odds ratio (OR) 1.106, 95% CI 1.028-1.191) and depression (OR 2.635, 95% CI 1.799-3.861) were significantly associated with an increased risk of EDS, and fair sleep quality (OR 0.560, 95% CI 0.318-0.985) was associated with a decreased risk of EDS. Almost one in three emergency physicians in South Korea suffer from daytime sleepiness. The number of monthly night-shift days and depression were associated with an increased risk of EDS.

Fatigue in Brazilian patients with Parkinson's disease.

Fatigue is a non-motor symptom of high prevalence in Parkinson's disease (PD); however, it is still unknown and neglected by health professionals. Objective: This study aimed to demonstrate the prevalence of fatigue in patients with PD after excluding confounding factors, as well as its correlation with clinical and demographic data, and to find its negative impact on the quality of life of these patients. Methods: A cross-sectional study was carried out with 237 randomly selected patients. According to inclusion and exclusion criteria, we selected 53 patients, who were then submitted to the Fatigue Severity Scale. Clinical and demographic data were also analyzed, comparing them between patients with and without fatigue. Results: We identified fatigue in 21 (39.62%) patients. Patients with and without fatigue had similar mean scores on the UPDRS-III (p=0.36), equivalent daily dose of levodopa (p=0.94), mean disease duration (p=0.43), and mean age (p<0.99). Fatigued patients had worse quality of life scores (PDQ-39) (p=0.00). We did not observe a correlation between fatigue, duration of illness (r=0.11; p=0.43), age (r=0.00; p=0.99), and UPDRS-III (r=0.20; p=0.16). Conclusions: Fatigue is a highly prevalent and independent symptom of PD. There is no correlation between age, mean duration of disease, motor impairment, and its presence. It has a negative impact on quality of life.

Analisaram-se também dados clínicos e demográficos, comparando-os entre os pacientes com e sem fadiga. Resultados: Identificamos fadiga em 21 pacientes (39,62%). Pacientes com e sem fadiga apresentaram pontuação média semelhante na Escala Unificada de Avaliação para Doença de Parkinson (UPDRS-III) (p=0,36), dose diária equivalente de levodopa (p=0,94), tempo médio de duração da doença (p=0,43) e idade média (p<0,99). Pacientes fatigados apresentaram piores índices de qualidade de vida (Parkinson's Disease Questionnaire - PDQ-39) (p=0,00). Não observamos correlação entre fadiga, tempo de doença (r=0,11; p=0,43), idade (r=0,00; p=0,99) e UPDRS-III (r=0,20; p=0,16). Conclusões: A fadiga é um sintoma de alta prevalência e independente na doença de Parkinson. Não há correlação entre idade, tempo médio de duração da doença, comprometimento motor e sua presença. Possui impacto negativo na qualidade de vida.

Validation of the Colombian version of the Karolinska sleepiness scale.

Introduction: Currently, daytime sleepiness is a prevalent condition worldwide. Locally validated instruments for measuring sleepiness are required. The objective of this study was to validate a version of the Karolinska sleepiness scale that was translated into the Spanish spoken in Colombia. Methods: Individuals who attended a sleep laboratory for a polysomnography study and people in the general population were included. The validation process was performed in 6 phases: translation and back translation of the original version of the scale (English), face validity (n=13), pilot test (n=20), criteria validity (n=139) by means of polysomnography and the Epworth sleepiness scale, reproducibility (n=34), and sensitivity to change (n=40). Results: Regarding its discriminant validity, the Colombian version of the Karolinska sleepiness scale is correlated with the Epworth sleepiness scale, provided that a Mann-Whitney z=2661 (p=0.0078) was obtained. The scale has an acceptable reproducibility, Spearman Rho=0.55 (p=0.0002), and sensitivity to change, as shown through a two-tailed t test (p=0.0000). Conclusions: The Karolinska Sleepiness Scale was successfully adapted to the Spanish variation spoken in Colombian and to the conditions of adult Colombians; thus, it constitutes a valid, reliable, and easy to use instrument for the assessment of patients with hypersomnia.

The association between diabetes and excessive daytime sleepiness among American adults aged 20-79 years: findings from the 2015-2018 National Health and Nutrition Examination Surveys.

PURPOSE: To examine the association between diabetes and excessive daytime sleepiness (EDS). METHODS: Using the 2015-2018 cycles of the National Health and Nutrition Examination Survey, we applied survey-featured modified Poisson regression to estimate the association between diabetes and EDS among American adults aged 20-79 years, adjusting for confounding demographic, clinical and lifestyle variables. Effect modification by age, sex, race, education, income, sleep apnea and inadequate sleep was assessed. We performed sensitivity analyses using propensity score matched (PS) data and applied ordinal logistic regression using multiple levels of daytime sleepiness. Among people with diabetes, we assessed the association between EDS and diabetes care variables. RESULTS: Of the 6289 participants, 895 (10%) had diabetes. The estimated prevalence of EDS was higher among adults with diabetes (30.6%) than counterparts without diabetes (26.3%). After adjusting for confounding variables, diabetes remained associated with EDS (aPR:1.20; 95%CI:1.06 1.36). There was no statistically significant effect modification. Sensitivity analyses confirmed our main results. Among people with diabetes, there was limited evidence that the diabetes care variables were related to EDS. CONCLUSIONS: Among American adults, diabetes is associated with EDS after controlling for confounding variables. Although the cross-sectional design is a limitation, our findings support further exploration of the role of diabetes in EDS.

Rendimiento y validación del puntaje NoSAS en la evaluación inicial del síndrome de apnea/hipopnea del sueño / Performance and validation of NoSAS score in sleep apnea-hypopnea syndrome initial assessment

Introducción: El método de referencia para diagnosticar el síndrome de apnea-hipopnea obstructiva del sueño (SAHOS) es la polisomnografía, esta no es diagnóstica en otros trastornos respiratorios del sueño, por lo que es necesario la implementación de puntajes predictivos para diferenciar aquellos pacientes que tienen más riesgos de padecer SAHOS y necesiten de una polisomnografía. El objetivo de este estudio fue validar el puntaje NoSAS y la escala de Berlín frente a la polisomnografía tipo 1 en pacientes con sospecha de SAHOS. Materiales y métodos: Estudio de pruebas diagnósticas. A 264 pacientes se les realizó una polisomnografía basal, la aplicación del puntaje NoSAS y la escala de Berlín; luego, se hizo el análisis de las pruebas diagnósticas y se calculó el rendimiento de cada una en relación con el índice de apnea hipopnea (IAH). Resultados: La sensibilidad del puntaje NoSAS para un IAH ≥ 20 fue 88,57% con intervalo de confianza (IC) 95% 80,4-96,74; especificidad 56,70 %; IC 95% 49,47-63,93 y valor predictivo negativo (VPN) de 93,22, IC 95% 91,70- 99,82. Para la escala de Berlín, la sensibilidad fue de 81,43%, IC 95% 71,60-91,25; especificidad de 58,76%, IC 95% 51,58-65,95 y VPN 89,76%, IC 95% 89,08-98,32. Conclusión: Se demostró que el puntaje NoSAS y la escala de Berlín tienen una buena sensibilidad para descartar a las personas con un menor riesgo de SAHOS. Un paciente clasificado de bajo riesgo probablemente está sano o tiene bajo riesgo para SAHOS moderado a severo y no requeriría de una polisomnografía inicial.

Introduction: The gold standard for diagnosing obstructive sleep apnea-hypopnea syndrome (OSAHS) is the polysomnography, and it is not a diagnostic tool for another sleep breathing disorders, so that it is necessary to implement predictive scores to differentiate those patients who have more risk of suffering OSAHS, therefore they need a polysomnography. The aim to this study was to validate the NoSAS score and Berlin scale in relation to the polysomnography type 1, in patients who have the clinical suspicion of OSAHS. Material and methods: Diagnostic tests study. 264 patients underwent polysomnography, and the NoSAS score and Berlin scale were applied to them. After that, the diagnostic tests analysis was done and the performance of each one of them was calculated in relation to the apnea- hypopnea index (AHI). Results: The sensitivity of the NoSAS score for an AHI ≥ 20 was 88.57%, confidence interval (CI) 95% (80.4-96.74), specificity 56.70 %, CI 95% (49.47-63.93), and the negative predictive value (NPV) was 93.22, CI 95% (91.70-99.82). For Berlin scale the sensitivity was 81.43%, CI 95% (71.60-91.25), specificity 58.76%, CI 95% (51.58-65.95) and NPV 89.76%, CI 95% (89.08-98.32). Conclusions: It was shown that NoSAS score and Berlin scale have a good sensitivity to rule out people who have less OSAHS risk. A patient classified as low risk, probably is healthy or at low risk for moderate to severe OSAHS and would not require an initial polysomnography.

Estudios de prevalencia del síndrome de apneas obstructivas del sueño en la población adulta / Studies of prevalence of obstructive sleep apnea syndrome in adult population

El síndrome de apnea-hipopnea obstructiva del sueño (SAHOS) es un trastorno respiratorio común asociado con múltiples consecuencias adversas para la salud y su prevalencia ha aumentado en paralelo con el aumento de la obesidad en la población. MÉTODOS: revisión sistemática que examina los estudios de prevalencia de SAHOS en la población general. Se incluyeron los estudios transversales y los componentes transversales de los estudios longitudinales que midieron objetivamente la prevalencia de SAHOS en adultos empleando instrumentos de laboratorio. Se evaluaron cuarenta estudios poblacionales de las 8.876 publicaciones encontradas en la búsqueda sistemática realizada en PubMed y otras bases de datos. RESULTADOS: Se ha observado importantes diferencias metodológicas en los estudios poblacionales, lo cual ha determinado una amplia variación en la prevalencia de SAHOS reportada, con un valor promedio de 36,9% (IC95% 28,3-45,4%) en hombres y 24,0% (IC 95% 16,3-31,6%) en mujeres. Se ha reportado un aumento en la prevalencia de SAHOS en el curso del tiempo desde 1987 hasta el 2020. Esta condición es más prevalente en varones, aumenta progresivamente con la edad y se asocia a la obesidad. La somnolencia diurna excesiva se ha asociado al diagnóstico de SAHOS, pero sólo una fracción de los sujetos con índice de apnea-hipopnea ≥ 5 eventos/hora presentan somnolencia diurna. CONCLUSIÓN: La prevalencia de SAHOS ha aumentado en los estudios poblacionales realizados en el curso del tiempo. La variabilidad reportada en la prevalencia de SAHOS probablemente esté relacionada con los diferentes equipos y definiciones operacionales empleados en el proceso diagnóstico, y las características de los sujetos examinados, incluyendo el importante aumento de la obesidad en la población.

Obstructive sleep apnea syndrome (OSAS) is a common disorder associated with multiple adverse health consequences and its prevalence is increasing in parallel with global rising in obesity. METHODS: We have developed a systematic review to examine obstructive sleep apnea syndrome prevalence studies in adults in the general population. We included the cross-sectional studies and the cross-sectional components of longitudinal studies that objectively measured OSAS in adults using laboratory instruments. Forty studies out of 8,876 articles found by systematically searching in PubMed and other databases were included in this review. RESULTS: Substantial methodological heterogeneity in population prevalence studies has been observed, determining a wide variation in OSAS prevalence defined at an apnea-hypopnea index (AHI) ≥ 5 events/hour, the average OSAS prevalence was 36.9% (CI95% 28.3-45.4%) in men and 24.0% (CI95% 16.3-31.6%) in women. The OSAS prevalence has increased over the time. OSAS is more prevalent in men than in women and increases with age and obesity. Excessive daytime sleepiness has been suggested as the most important symptom associated to OSAS, but only a fraction of subjects with AHI ≥ 5 events/hour report daytime sleepiness. CONCLUSION: The prevalence of OSAS has increased in epidemiological studies over time. The differences in reported prevalence of obstructive sleep apnea are probably due to different diagnostic equipment, operational definitions, study design and characteristics of included subjects, including effects of the obesity epidemic.
