Clinical, psychological and environmental factors that affect sleep quality of in surgical patients / Fatores clínicos, psicológicos e ambientais que afetam a qualidade de sono do doente cirúrgico

Objective: To assess the quality of sleep among surgical inpatients and to determine the associated clinical, environmental, and psychological factors. Method: A cross-sectional observational study using descriptive correlation analysis was conducted on 150 surgical inpatients at a Portuguese hospital center. A sociodemographic and clinical questionnaire and the Pittsburgh Sleep Quality Index - Portuguese version (PSQI-PT) were administered. Result: Most participants seemed to experience poor sleep quality (PSQI > 5 = 89.3%) during hospitalization.Factors associated with poor sleep quality include several clinical variables whose scores were significantly worse among cancer patients, patients undergoing colorectal surgery or esophagogastroduodenoscopies, those with longer hospital stays, and those experiencing pain and health-related complications. Variables related to sleep disturbances included noise, persistent changes in sleeping position, feelings of anxiety, and health concerns. Conclusion: Findings revel a high prevalence of poor sleep quality during hospitalization caused by an increased sleep latency period, a decline in total sleep time, and lower sleep efficiency

Objetivo: Avaliar a qualidade de sono do doente cirúrgico internado e determinar os fatores clínicos, ambientais e psicológicos associados. Método: Estudo observacional com matriz transversal e análise descritivo-correlacional, realizado com 150 doentes internados para procedimento cirúrgico, num centro hospitalar português. Foi aplicado um questionário para caracterização sociodemográfica e clínica, bem como o Índice de Qualidade do Sono de Pittsburgh ­ versão portuguesa (PSQI-PT). Resultado: A maioria dos participantes apresentou uma má qualidade de sono (PSQI > 5 = 89,3%) durante o internamento. Os fatores associados à má qualidade de sono incluem variáveis clínicas com piores escores nos doentes oncológicos, submetidos a cirurgia colorretal e esofagogastroduodenal, maior tempo de internamento, presença de dor e complicações. Como variáveis perturbadoras do sono destacam-se o ruído, a alteração da posição para dormir, sentir-se ansioso e a preocupação com a própria saúde. Conclusão: Observou-se uma elevada prevalência da má qualidade de sono, resultante do aumento do período de latência, diminuição do tempo total de sono e da sua eficiência durante o internamento

The Sleep Parameters of Olympic Athletes: Characteristics and Assessment Instruments.

This systematic review aims to identify the sleep parameters of Olympic athletes and the instruments used to assess and monitor the sleep of these athletes. The search was conducted until February 2023 and was performed in PubMed, Web of Science, and Scopus databases. This systematic review has included studies that investigated at least one of the following sleep parameters: total sleep time (TST), sleep onset latency (SOL), sleep efficiency (SE), awakenings after sleep onset (WASO), quality of sleep, daytime sleepiness, and chronotype; the participants were Olympic athletes. The search returned a total of 280 studies. After screening based on exclusion and inclusion criteria, 11 studies were included. The main results demonstrate that Olympic athletes have TST of 06:10 h, SE of 84%, SOL of 28 min, and WASO of 49 min. The most predominant chronotype is indifferent; over half of the athletes have poor sleep quality and complaints. Furthermore, actigraphy was the most used method to assess sleep. It is concluded that Olympic athletes have TST, SE, and WASO poor than the recommended values. In addition, sleep complaints and poor sleep quality were also observed. Among the objective sleep assessment methods, actigraphy was the method most frequently used in this population.

¿Qué es el test de latencia múltiple de sueño y cuál es su uso en pediatría? / What is the multiple sleep latency test and what is its use in pediatrics?

La prueba de latencia múltiple del sueño nos permite evaluar objetivamente las variaciones normales y patológicas en la somnolencia y el estado de alerta. Es una prueba que evalúa qué tan rápido una persona se duerme en condiciones estandarizadas que facilitan el sueño, y se repite a intervalos de 2 horas durante todo el día. Es el estándar para documentar el inicio del sueño REM (SOREMP), que es un síntoma de narcolepsia y en la somnolencia idiopática podría ser útil. Su uso está ampliamente descrito en adultos, pero la prueba no es tan común en niños. En esta revisión, se analizan los valores en adultos y niños, y su utilidad, a partir de la historia de la prueba.

The multiple sleep latency test allows us to objectively assess normal and pathological variations in sleepiness and alertness. It is a test that assesses how quickly a person falls asleep under standardized conditions that facilitate sleep and is repeated at 2-h intervals throughout the day. is the standard for documenting sleep onset REM (SOREMP), which is a symptom of Narcolepsy and idiopathic sleepiness could be useful. Its use is widely described in adults, but the test is not so common in children. In this review, we analyze the values in adults and children, and their usefulness, based on from the history of the test.

The Influence of Different Training Load Magnitudes on Sleep Pattern, Perceived Recovery, and Stress Tolerance in Young Soccer Players.

ABSTRACT: Ferreira, ABdM, Ribeiro, BLL, Batista, EdS, Dantas, MP, and Mortatti, AL. The influence of different training load magnitudes on sleep pattern, perceived recovery, and stress tolerance in young soccer players. J Strength Cond Res 37(2): 351-357, 2023-The aim of this study was to analyze the influence of 3 weeks on sleep parameters, perceived recovery, and stress tolerance in young soccer players using different training load magnitudes. A total of 13 young male soccer athletes (15.9 ± 0.5 years; 68.7 ± 6.1 kg; 170 ± 7 cm) who performed 3 typical training weeks with different workloads were analyzed. The external training load (ETL) was verified by the PlayerLoad method, and the internal training load (ITL) was determined using the session rating of perceived exertion method. Sleep was monitored using a wrist-actigraphy monitor. Sleep variables, including total time in bed (TTB), total sleep time (TST), sleep latency (SL), wake after sleep onset (WASO), and sleep efficiency (SE), were evaluated across all nights of sleep. The recovery status was assessed with the perceived recovery status (PRS) scale, and the stress tolerance was monitored using the "daily analysis of life demands of athletes" questionnaire. There was an increase in sleep time during the week with the highest training load (week 2) (TTB: +35 minutes, TST: +46 minutes, SL: -5 minutes, SE: +3%). There was no difference in the PRS or in the stress tolerance during the evaluation weeks. A very large within-individual correlation was observed between ITL and ETL ( r = 0.78) and moderate within-individual correlation between ETL and TST ( r = 0.34), between ITL and TST ( r = 0.45), and between ITL and SE ( r = 0.359). These results showed that there was an increase in TST during a microcycle with intensified loads, without impairing bedtime and resulting in maintenance of the perceived recovery or stress tolerance values.

Narcolepsia na infância: a atuação multidisciplinar com a psicologia do sono do diagnóstico ao tratamento em um relato de caso / Child narcolepsy: the multidisciplinary approach with sleep psychology from diagnostics to treatment in a case report / Narcolepsia en la infancia: actuación multidisciplinar con la psicología del sueño desde el diagnóstico hasta el tratamiento en un caso clínico

A narcolepsia, distúrbio neurológico crônico caracterizado pela sonolência diurna excessiva, pode ser associada à cataplexia, fragmentação do sono, alucinações relacionadas ao sono e paralisia do sono. Frequentemente, é confundida com outros transtornos, como Transtorno do Déficit de Atenção com Hiperatividade (TDAH), epilepsia e até esquizofrenia, assim, por vezes, é diagnosticada inadequadamente. Objetiva-se relatar o diagnóstico diferencial bem-sucedido da narcolepsia na infância e suas dificuldades, realizado por uma equipe multidisciplinar, enfocando a atuação da psicologia do sono em avaliação e intervenção. Um menino de 10 anos foi recebido no Ambulatório de Narcolepsia e Apneia do Sono Infantil (AMBNAP), alocado no Hospital Universitário Onofre Lopes da Universidade Federal do Rio Grande do Norte (UFRN) com queixas de sonolência diurna excessiva, sono fragmentado e episódios de perda de tônus muscular. Foi submetido a entrevistas psiquiátrica e psicológica pormenorizadas, a exames, aplicação de escalas específicas para rastreio e diagnóstico de transtornos de sono e diário de sono, solicitação de recursos de mídia e de relatório escolar e avaliação neurológica. A partir da investigação multidisciplinar, o diagnóstico foi de Narcolepsia e Síndrome da Apneia Obstrutiva do Sono (SAOS). O paciente foi submetido a técnicas da Terapia Cognitivo-Comportamental (TCC) e segue em acompanhamento, apresentando resultados satisfatórios. Este estudo evidencia que uma equipe multidisciplinar especializada na área de sono atuando em conjunto com a Psicologia do Sono oportuniza o diagnóstico e intervenções precoces eficazes para o tratamento do distúrbio do sono na infância.(AU)

Narcolepsy is a chronic neurologic disorder characterized by excessive daytime sleepiness which can be associated with cataplexy, sleep fragmentation, sleep-related hallucinations, and sleep paralysis. This sleep disorder is often confused with other disorders such as Attention Deficit Hyperactivity Disorder (ADHD), epilepsy, and even schizophrenia, and is, thus, misdiagnosed. This study aims to report the successful differential diagnosis for childhood narcolepsy carried out by a multidisciplinary team and its challenges, with a focus on the role of sleep psychology in assessment and intervention. A 10-year-old child was received at the Child Narcolepsy and Sleep Apnea Clinic (AMBNAP), located at the Onofre Lopes University Hospital of the Federal University of Rio Grande do Norte (UFRN), with complaints of hypersomnolence, fragmented sleep, and episodes of loss of muscle tone. He underwent detailed psychiatric and psychological interviews, analysis of exams, application of specific scales for screening and diagnosis of sleep disorders and sleep diary, request of media resources and school report, and neurological assessment. From the multidisciplinary investigation, excluding of other neurological diagnoses, the diagnosis was Narcolepsy and Obstructive Sleep Apnea Syndrome (OSAS). The patient was submitted to Cognitive Behavioral Therapy (CBT) techniques, such as psychoeducation, scheduled naps, cognitive therapy for dysfunctional beliefs, and sleep hygiene strategies, and continues to be followed up, with satisfactory results since the first two months of intervention. The findings presented in this study show that a multidisciplinary team specialized in the sleep area, acting alongside Sleep Psychology provides early diagnosis and interventions for the sleep disorder treatment in childhood.(AU)

El paciente fue sometido a técnicas de terapia cognitivo-conductual (TCC), como psicoeducación, siestas programadas, terapia cognitiva por creencias disfuncionales y estrategias de higiene del sueño, y se le dio seguimiento con resultados satisfactorios. Los resultados demostraron que un equipo multidisciplinario especializado en el campo del sueño, actuando en conjunto con la psicología del sueño, proporciona el diagnóstico y las intervenciones tempranas para el trastorno del sueño de la narcolepsia en la infância.(AU)

A single nucleotide polymorphism in the HOMER1 gene is associated with sleep latency and theta power in sleep electroencephalogram.

Glutamate is the most excitatory neurotransmitter in the central nervous system and it is involved in the initiation and maintaining of waking and rapid-eye-movement (REM) sleep. Homer proteins act in the trafficking and/or clustering of metabotropic glutamate receptors, and polymorphisms in the HOMER1 gene have been associated with phenotypes related to glutamate signaling dysregulation. In this study, we report the association of a single nucleotide polymorphism (SNP) in the HOMER1 gene (rs3822568) with specific aspects of sleep in a sample of the Brazilian population. To accomplish this, 1,042 individuals were subjected to a full-night polysomnography, and a subset of 983 subjects had rs3822568 genotyping data available. When compared with the A allele carriers, GG genotyped individuals showed higher sleep latency, lower sleep efficiency, reduced number of arousals per hour, lower apnea-hypopnea index (AHI) and lower theta spectral power. In summary, the present findings suggest that the rs3822568 polymorphism in the HOMER1 gene is associated with sleep EEG profiles and might have an impact on sleep quality and sleep structure, with potential to explain inter-individual variation in sleep homeostasis.

Differences in electroencephalographic spectra during pre-sleep wakefulness, N1, and R sleep between comorbid insomnia and obstructive sleep apnea.

PURPOSE: The neuropsychobiological effects of the comorbidity of insomnia and obstructive sleep apnea are not well studied. Our objective was to compare electroencephalographic spectra of patients with comorbid insomnia and sleep apnea syndrome to those of patients with sleep apnea syndrome alone during pre-sleep wakefulness and the N1 and R sleep periods. METHOD: We performed electroencephalography and polysomnography on 10 patients with comorbid insomnia and sleep apnea and 10 with only sleep apnea. Electroencephalography spectra analysis was performed for absolute power in clinical bands in six derivations. RESULTS: Compared to sleep apnea patients, comorbid patients had lower sleep efficiency and total sleep time, higher beta-1 power in the left frontal and central derivations during pre-sleep wakefulness, higher delta power in the left frontal and central derivations during the N1 stage, and higher beta-2 power in the left frontal and central, and right central derivations during the R stage. CONCLUSIONS: Data suggest that patients with insomnia and sleep apnea, compared to patients with only sleep apnea, presented higher left high-frequency rhythms during pre-sleep wakefulness and R sleep stage, and may be for increased emotional and cognitive-related activity, while in stage N1, presented higher left delta power, which suggest some slowing after sleep deprivation.

Sleep quality and fatigue in women with premature ovarian insufficiency receiving hormone therapy: a comparative study.

OBJECTIVE: To compare sleep quality and fatigue between women with premature ovarian insufficiency (POI) receiving hormone therapy (HT) and women of the same age with preserved ovarian function. METHODS: This was a cross-sectional study of 61 women with POI receiving HT (POI group) and 61 women with preserved ovarian function (control group) who were matched by age (±2 years). The Pittsburgh Sleep Quality Index (PSQI) and Chalder Fatigue Scale were used to assess sleep quality and fatigue. Apart from correlation analysis, the Mann-Whitney, chi-square, or Fisher test was used to compare the groups. RESULTS: Women from the POI and control groups were 35.03 ±â€Š7.68 and 34.49 ±â€Š7.55 years of age, respectively (P = 0.63). In the PSQI evaluation, the scores were 7.69 ±â€Š4.18 and 8.03 ±â€Š4.53, respectively (P = 0.79), showing no difference between the POI and control groups. However, the POI group had higher and therefore worse scores for the sleep latency component (1.74 ±â€Š0.66 and 1.18 ±â€Š0.87, respectively; P < 0.001) and use of medication to sleep (1.28 ±â€Š0.88 and 0. 85 ±â€Š0.8; P = 0.008). The POI group had a higher fatigue index than that of the control group (5.25 ±â€Š2.78 and 3.49 ±â€Š1.78, respectively; P < 0.001), with sleep quality being classified as poor in 69% and fatigue present in 59% of patients. CONCLUSIONS: Women with POI receiving HT have poor sleep quality. They take longer to fall asleep and have a higher fatigue index.

Sleep disorders in NiemannPick disease type C, beyond cataplexy.

PURPOSE: The aim of this study was to clinically characterize sleep disorders in a cohort of Niemann-Pick type C (NPC) patients, correlating these findings with disease features and polysomnographic (PSG) results. METHODS: We evaluated eight consecutive patients with molecular confirmation of NPC followed at the Hospital Geral de Fortaleza. Patients underwent a comprehensive neurological and sleep evaluation. Four participants underwent polysomnography and then performed the multiple sleep latency test. RESULTS: All eight patients evaluated had sleep disorders. Four participants performed polysomnography followed by multiple sleep latency test. Chronic insomnia and Obstructive Sleep Apnea (OSA) were the most frequent sleep disorders (62,5%). Two patients were diagnosed with Restless Legs Syndrome (RLS) (25%) and two with probable REM sleep behavior disorder (RBD) (25%). All the patients who did polysomnography had reduced and/or disorganized sleep, with reduction on sleep efficiency, total sleep time and REM sleep time. CONCLUSION: Our results suggest that sleep abnormalities in Niemann-Pick type C patients may be more prevalent than previously thought.

Eating Late Negatively Affects Sleep Pattern and Apnea Severity in Individuals With Sleep Apnea.

STUDY OBJECTIVES: This study aimed to analyze the association between habitual meal timing and sleep parameters, as well as habitual meal timing and apnea severity in individuals with obstructive sleep apnea (OSA). METHODS: Patients in whom mild to severe OSA was diagnosed were included in the study (n = 296). Sleep parameters were analyzed by polysomnography. Dietary pattern was obtained by a food frequency questionnaire and meal timing of the participants. Individuals with OSA were categorized by meal timing (early, late, and skippers). RESULTS: Dinner timing was associated with sleep latency (ß = 0.130, P = .022), apnea-hypopnea index (AHI) (ß = 1.284, P = .033) and poor sleep quality (ß = 1.140, P = .015). Breakfast timing was associated with wake after sleep onset (WASO) (ß = 3.567, P = .003), stage N1 sleep (ß = 0.130, P < .001), and stage R sleep (ß = -1.189, P = .001). Lunch timing also was associated with stage N1 sleep (ß = 0.095, P = .025), sleep latency (ß = 0.293, P = .001), and daytime sleepiness (ß = 1.267, P = .009). Compared to early eaters, late eaters presented lower duration of stage R sleep and greater values of sleep latency, WASO, stage N1 sleep, and AHI, in addition to increased risk of poor sleep quality and daytime sleepiness (P < .005). CONCLUSIONS: Late meal timing was associated with worse sleep pattern and quality and apnea severity than early meal timing. Despite some of these results having limited clinical significance, they can lead to a better understanding about how meal timing affects OSA and sleep parameters.

Temporal Analysis of Chronic Musculoskeletal Pain and Sleep in Postmenopausal Women.

STUDY OBJECTIVES: To investigate the temporal association between chronic musculoskeletal pain (CMP) and sleep in women who are postmenopausal in a 10-day actigraphic study. This is a microlongitudinal study in which 52 participants were allocated to 4 groups women who are postmenopausal: control (CTRL, n = 10), chronic musculoskeletal pain (CMP, n = 12), insomnia (INS, n = 15) and chronic musculoskeletal pain+insomnia (CMP+INS, n = 15). METHODS: All volunteers underwent a clinical interview and completed questionnaires, used an actigraph, and kept sleep diaries for 10 consecutive days. RESULTS: Women in the CMP+INS group presented more sleep episodes (mean of 1.02 episodes) and longer sleep latency (8.97 minutes), as well as higher pain intensity during the day compared to the other groups. Sleep duration recorded by actigraphy directly predicted pain intensity the following morning on waking, with a 1-unit increase in pain intensity, for every 6.9 minutes more of sleep. Higher pain intensity at bedtime was a significant predictor of both increased time in bed and sleep duration, meaning that for each 1-unit increase in pain intensity at bedtime, sleep duration increased by an average of 6.7 minutes. CONCLUSIONS: Data showed that the coexistence of insomnia and CMP results in greater pain intensity and alterations in sleep homeostasis. Collectively, the data indicate that there is a bidirectional and directly proportional relationship between sleep duration and pain intensity in women who are postmenopausal with insomnia. This result strongly suggests that both sleep and pain conditions should be targeted in the treatment of women who are postmenopausal.

The bidirectional association between physical activity and sleep in middle-aged and older adults: a prospective study based on polysomnography.

Study Objectives: To examine the bidirectional association between physical activity (PA) and polysomnographically (PSG)-assessed sleep parameters characterized by total sleep time (TST), sleep onset latency (SOL), wake time after sleep onset (WASO), sleep efficiency and percentage of TST in N1, N2, and N3 stages and rapid eye movement (REM) sleep in middle-aged and older adults. Methods: Longitudinal study based on a subsample of the Wisconsin Sleep Cohort. Self-reported PA information was used to estimate the metabolic equivalents of task (MET-minutes/week) activity and in-laboratory PSG exams provided information on sleep parameters at baseline and after 3-11 years of follow-up between 2004 and 2015. Poisson and linear regression models controlling for confounders estimated associations of sleep outcomes with changes in PA. Results: A total of 424 participants (45.8% female; mean ± SD age 60.1 ± 7.5 years) were followed over an average of 5.0 ± 1.6 years. Compared to baseline PA of <500 MET-minutes/week (reference category), 500 to 1500 MET-minutes/week of PA was associated with lower incidences of TST <6 hours (relative risk, RR: 0.49; 95% confidence interval, CI: 0.27; 0.88), WASO >60 minutes (RR: 0.58; 95% CI: 0.41; 0.82) and sleep efficiency <80% (RR: 0.61; 95% CI: 0.39; 0.94), adjusting for sociodemographic, health behaviors and medical conditions. No significant associations were observed between baseline sleep characteristics and changes in PA through the follow-up. Conclusion: In this prospective study, an intermediate level of PA at baseline predicted lower risk of incident short sleep time, higher WASO and lower sleep efficiency measured with PSG.

She repeatedly receives a diagnosis of epilepsy, with normal EEG studies and brain MRI. She received a 12 month course of valproic acid treatment. A polysomnogram and multiple sleep latency test were subsequently performed, confirming a diagnosis of narcolepsy and a mood disorder. She begins treatment with antidepressants and psychostimulants. At follow up, she shows an improvement of her cataplexy, hypersomnia and mood disorder.We analyze this case to consider this pathology in the differential diagnosis of children with daytime hypersomnolence and episodes of muscle tone loss, with conserved awareness, as well as to discuss management and associated comorbidities.

Características polisomnográficas nocturnas y otras variables relacionadas, en pacientes adultos mayores / Nocturnal polysomnbnographic characteristics and other related variables in elderly patients

Se cree que los ancianos necesitan dormir menos. Sin embargo, no es la necesidad de sueño sino la capacidad de dormir lo que disminuye con la edad, en paralelo a la mayor prevalencia de enfermedades cardiovasculares o metabólicas, o de depresión. Poco se ha descripto sobre los hallazgos polisomnográficos de esta población. En el presente estudio analizamos los hallazgos polisomnográficos en pacientes mayores de 65 años. Se realizó un estudio descriptivo a partir del análisis de una base de datos de 551 pacientes mayores de 65 años evaluados entre junio de 2013 y diciembre de 2014. Todos los sujetos se realizaron una polisomnografía (PSG) nocturna de 6 horas de duración. Las variables analizadas fueron: latencia de sueño (LS), eficacia de sueño (ES), latencia de fase REM (Lat R), % de R, índice de apneas hipopneas (IHA) y movimientos periódicos de piernas durante el sueño (PLMS). Se dividió la población en 3 grupos: G1: de 65 a 70 años; G2: 71 a 75; G3: mayor de 75 años. Se analizaron los datos de la serie general y las diferencias intergrupos. El IHA se incrementó con la edad y resultó más severo en los pacientes mayores de 75 años en relación con el grupo de menor edad. El incremento del IAH no se asoció a un incremento del índice de masa corporal ni a mayor somnolencia diurna. (AU)

It is believed that the elderly need less sleep. However, it is not the need for sleep but the ability to sleep that decreases with age, in parallel to the increasing prevalence of cardiovascular or metabolic disease, or depression. Little has been described about the polysomnographic findings of this population, hypothesizing that there are several alterations that prematurely corrected could improve the quality of life as the years go by. We analyzed the polysomnographic findings in patients over 65 years of age. A descriptive study was carried out based on the analyses of a database of 551 patients over 65 years of age evaluated between June 2013 to December 2014. All subjects underwent nocturnal PSG of 6 hours duration. The polysomnographic variables analyzed were: sleep latency (LS), sleep efficiency (ES), latency R phase (Lat R), % R, Apneas Hypoapneas Index (AHI) and Periodic Limb Movements of Sleep (PLMS). The population was divided into 3 groups: G1: from 65 to 70 years G2: 71 to 75, G3 greater than 75. AHI increased with age, being more severe in patients over 75 years of age in relation to the younger age group. The increase in AHI was not associated with an increase in Body Mass Index (BMI) or greater daytime sleepiness. (AU)

Qualidade do sono em pacientes colostomizados / Quality of sleep in colostomized patients

Objetivo: este estudo tem como objetivo quantificar e qualificar o sono de pacientes colostomizados através do emprego do questionário de Pittsburgh (PSQI). Método: trata-se de um estudo transversal, envolvendo a coleta de dados através da aplicação do Índice de Qualidade do Sono de Pittsburgh (PSQI), associado à análise da colostomia quanto à sua duração e ao seu aspecto (plana ou protusa). Foram incluídos no estudo os pacientes portadores de colostomia há mais de um ano, com a idade variando entre 40 e 85 anos e sem distúrbios prévios do sono. Resultados: foram colhidos 50 questionários (n=50) e a análise qualitativa mostrou que 33 (66%) pacientes apresentam uma boa qualidade do sono com score ≤5 e que 17 (34%) pacientes tinham uma moderada ou ruim qualidade do sono com score >5. Com relação ao aspecto da colostomia, foi observado a plana em 6 (12%) casos, sendo que em somente 1 caso apresentou score ≤5, ou seja, de qualidade boa do sono. No aspecto protuso, que ocorreu em 44 casos (88%), observou-se que 32 (72,7%) pacientes apresentaram score ≤5, portanto uma boa qualidade de sono. Outro parâmetro analisado foi o impacto dos Componentes Individuais da Qualidade de Sono (CIQS: duração do sono, distúrbio do sono, etc.) com relação à qualidade de sono geral (r). Foi constatado que o Distúrbio do Sono tem menor impacto (r=0,409) se comparado com o uso de medicamentos para dormir (r=0,860). Ficou claro também quanto à diferença entre o impacto relativo dos CIQS quando comparados entre os grupos da colostomia plana e protusa, sendo que, no grupo de pacientes com a colostomia plana em todos os quesitos, obteve-se maior impacto na qualidade de sono geral (r>0,877). Já o impacto dos CIQS na qualidade de sono geral em colostomias protusas teve seu maior índice no Uso de Medicamentos (r=0,762) enquanto que o Distúrbio do Sono (r=0,187) recebeu o menor índice. Conclusão: o aspecto final da colostomia é importante para a qualidade do sono do colostomizado, sendo a protusa a que teve menor influência negativa nesta situação.

Objective: this study aims to quantify and qualify sleep of colostomized patients using the Pittsburgh Questionnaire (PSQI). Methods: this is a cross-sectional study involving the collection of data through the application of the Sleep Quality Index Of Pittsburgh (PSQI); Associated with colostomy analysis, its duration and its appearance (flat or protusa). Patients with colostomy for more than one year, ranging in age from 40 to 85 years, were included in the study. Results: fifty questionnaires were collected (n=50) and the qualitative analysis showed that 33 (66%) patients had a good quality of sleep with a score ≤5 and that 17 (34%) patients had moderate or poor quality of sleep with Score >5. Regarding the aspect of the colostomy, the flat was observed in 6 (12%) cases, and in only 1 case presented a score ≤5, that is, of good sleep quality. In the protruding aspect, which occurred in 44 cases (88%), it was observed that 32 (72.7%) patients presented scores ≤5, therefore a good quality of sleep. Another parameter analyzed was the impact of the Individual Components of Sleep Quality (CIQS: sleep duration, sleep disturbance, etc.) in relation to general sleep quality (r). It was found that Sleep Disorder had a lower impact (r=0.409) when compared to sleeping medication (r=0.860). It was also clear how the difference between the relative impact of CIQS when compared between the flat and protuberant colostomy groups. As in the group of patients with flat colostomy, in all the questions, it was obtained a greater impact in the quality of general sleep (r>0.877). On the other hand, the impact of CIQS on general sleep quality in protusial colostomies had its highest index in the Use of Medications (r=0.762), while sleep disturbance (r=0.187) received the lowest index. Conclusion: the final appearance of the colostomy is important for the quality of sleep of the colostomy, being the protusa the one that less influence negatively in this situation.

Lung Disease Associated With Marijuana Use. / Patología pulmonar asociada al consumo de marihuana.

Marijuana is the most widely usedillegal drug in the world, with a prevalence of 2.5%-5%, and the second most commonly smoked substance after tobacco. The components of smoke from combustion of marijuana are similar to those produced by the combustion of tobacco, but they differ in terms of psychoactive components and use. Inhalation of cannabis smoke affects the respiratory tract, so the available evidence must be updated in order to provide pulmonologists with the latest scientific information. In this article, we review the impact of cannabis consumption on the lungs, taking into account that the respiratory route is the most popular route of cannabis consumption.

Brazilian air traffic controllers exhibit excessive sleepiness / Controladores de tráfego aéreo brasileiros apresentam sonolência excessiva

Abstract ­ Excessive sleepiness (ES) is an increased tendency to initiate involuntary sleep for naps at inappropriate times. Objective: The objective of this study was to assess ES in air traffic controllers (ATCo). Methods: 45 flight protection professionals were evaluated, comprising 30 ATCo, subdivided into ATCo with ten or more years in the profession (ATCo≥10, n=15) and ATCo with less than ten years in the profession (ATCo<10, n=15) and 15 aeronautical information services operators (AIS), subdivided into AIS with ten years or more in the profession (AIS≥10, n=8) and AIS with less than ten years in the profession (AIS<10, n=7), who were included as the control group. The Epworth Sleepiness Scale and Maintenance of Wakefulness Test were used for evaluating subjective and objective excessive sleepiness. Kruskal-Wallis was used for ES and Mann-Whitney for sleep latency (SL), collection time in minutes (mins), and expressed as Median (Minimum-Maximum), p<0.05. Results: ATCo≥10 12 (6-14) mins and ATCo<10 10 (1-15) mins showed greater sleepiness compared to CONTROL1 7 (3-8) mins and CONTROL2 6 (4-6) mins, p=0.001*. A total of 77.27% of the ATCo and 16.67% of the AIS had an SL of less than 20 minutes. The ATCo presented an SL of 16.59 (3.25-40), lower than that of the AIS of 31.71 (10.63-40) mins, p<0.05*. Conclusion: Brazilian air traffic controllers exhibit excessive sleepiness.

Resumo ­ A sonolência excessiva (SE) é a uma tendência aumentada de se iniciar o sono por cochilos involuntários em momentos inapropriados. Objetivo: O objetivo deste trabalho foi avaliar SE em controladores de trafego aéreo (CTA). Métodos: Foram avaliados 45 profissionais de proteção ao voo, sendo 30 CTA, subdivididos em CTA com dez ou mais anos na profissão (CTA≥10, n=15) e CTA com menos de dez anos na profissão (CTA<10, n=15) e 15 operadores de serviços de informações aeronáuticas (AIS), subdivididos em AIS com dez anos ou mais na profissão (AIS≥10, n=8) e AIS com menos de dez anos na profissão (AIS<10, n=7). A Escala de Sonolência de Epworth e o Teste de Manutenção da Vigília foram empregados para avaliação subjetiva e objetiva de sonolência excessiva. Utilizou-se: Kruskal-Wallis para os dados de SE e Mann-Whitney para a latência de sono. Tempo coletado em minutos (mins). Todos os dados foram expressos em mediana (mínimo-máximo), p<0,05). Resultados: CTA≥10 12 (6-14) mins e CTA<10 10 (1-15) mins apresentaram um aumento de sonolência, quando comparados ao CONTROLE1 7 (3-8) mins e ao CONTROLE2 6 (4-6) mins, p=0,001*. 77,27% dos CTA e 16,67% dos AIS apresentaram latência de sono abaixo de 20 minutos. Os CTA apresentaram uma latência de sono de 16,59 (3,25-40) mins abaixo dos AIS 31,71(10,63-40), p<0,05*. Conclusão: Controladores de tráfego aéreo apresentam sonolência excessiva
