Sleep quality analysis in individuals with acute coronary syndrome / Análisis de la calidad del sueño en individuos con síndrome coronario agudo / Análise da qualidade do sono em indivíduos com síndrome coronariana aguda

ABSTRACT Objective: to assess the prevalence of sleep disturbances and factors associated with sleep quality in patients with Acute Coronary Syndrome. Method: this is a cross-sectional study, carried out in the Cardiology Unit of a public university hospital, from October 2021 to December 2022, with patients hospitalized for Acute Coronary Syndrome over 18 years old. Sociodemographic and clinical data were collected, and sleep quality was measured by the Pittsburgh Sleep Quality Index. Statistical association tests were performed, considering a value of p<0.05 as significant. Results: a total of 96 patients were included, the majority being male, married and with a mean age of 63 years. The most prevalent comorbidities were hypertension, dyslipidemia and diabetes. It was identified that 92% had alteration in sleep quality and that the number of hours slept (p.<0.01), time to start sleep (p.0.03), sleep latency (p.<0.01), sleep duration (p.<0.01), habitual sleep efficiency (p.<0.02) and daytime sleepiness and daytime dysfunction (p.0.01) were significantly associated with sleep quality. There was a weak but significant correlation between age (r-0.22, p.0.02) and the presence of obstructive coronary lesions (r-0.23; p.0.02) with the Pittsburgh Sleep Quality Index score. Conclusion: most patients with acute coronary syndrome were classified as poor sleepers, therefore educational interventions to promote sleep should be performed in this population to reduce cardiovascular risk.

RESUMEN Objetivo: evaluar la prevalencia de trastornos del sueño y factores asociados a la calidad del sueño en pacientes con Síndrome Coronario Agudo. Método: estudio transversal, realizado en la Unidad de Cardiología de un hospital universitario público, de octubre de 2021 a diciembre de 2022, con pacientes hospitalizados por Síndrome Coronario Agudo mayores de 18 años. Se recogieron datos sociodemográficos y clínicos, y la calidad del sueño se midió mediante el Índice de Calidad del Sueño de Pittsburgh. Se realizaron pruebas de asociación estadística, considerando significativo un valor de p<0,05. Resultados: se incluyeron 96 pacientes, la mayoría hombres, casados ​​y con una edad media de 63 años. Las comorbilidades más prevalentes fueron hipertensión arterial sistémica, dislipidemia y diabetes. Se identificó que el 92% presentaba cambios en la calidad del sueño y que la cantidad de horas dormía (p.<0,01), tiempo de inicio del sueño (p.0,03), latencia del sueño (p.<0,01), duración del sueño (p.<0,01), eficiencia del sueño (p.<0,02) y somnolencia diurna y disfunción diurna (p.0,01) se asociaron significativamente con la calidad del sueño. Hubo una correlación débil pero significativa entre la edad (r-0,22, p.0,02) y la presencia de lesiones coronarias obstructivas (r-0,23; p.0,02) con el puntaje del Pittsburgh Sleep Quality Index. Conclusión: la mayoría de los pacientes con Síndrome Coronario Agudo fueron clasificados como insomnes, por lo que se deben realizar intervenciones educativas para promover el sueño en esta población para reducir el riesgo cardiovascular.

RESUMO Objetivo: avaliar a prevalência de distúrbios do sono e os fatores associados à qualidade do sono em pacientes com Síndrome Coronariana Aguda. Método: estudo transversal, realizado na Unidade de Cardiologia de um hospital público universitário, no período de outubro de 2021 a dezembro de 2022, com pacientes hospitalizados por Síndrome Coronariana Aguda maiores de 18 anos. Foram coletados dados sociodemográficos e clínicos, e a qualidade do sono foi mensurado pelo Índice de Qualidade do Sono de Pittsburgh. Testes estatísticos de associação foram realizados, sendo considerado um valor de p<0,05 como significativo. Resultados: foram incluídos 96 pacientes, sendo a maioria do sexo masculino, casados e com idade média de 63 anos. As comorbidades mais prevalentes foram hipertensão arterial sistêmica, dislipidemia e diabetes. Foi identificado que 92% tinham alteração na qualidade do sono e que a quantidade de horas dormidas (p.<0,01), o tempo para iniciar o sono (p.0,03), a latência do sono (p.<0,01), duração do sono (p.<0,01), eficiência do sono (p.<0,02) e sonolência diurna e disfunção diurna (p.0,01) apresentaram associação significativa com a qualidade do sono. Houve correlação fraca, porém, significativa entre a idade (r-0,22, p.0,02) e a presença de lesões obstrutivas coronarianas (r-0,23; p.0,02) com o escore do Pittsburgh Sleep Quality Index. Conclusão: a maioria dos pacientes com Síndrome Coronariana Aguda foram classificados como maus dormidores, portanto intervenções educativas para promoção do sono devem ser realizadas nesta população para a redução no risco cardiovascular.

Calidad del sueño en pacientes con enfermedad renal crónica / Sleep quality in patients with chronic kidney disease

Introducción: los pacientes con enfermedad renal crónica (ERC), y en específico los que tienen tratamiento renal sustitutivo (TRS), se ven afectados en su ciclo circadiano y en su calidad del sueño. Objetivo: evaluar la calidad del sueño de los pacientes con enfermedad renal crónica que acuden al servicio de Nefrología de una unidad médica de segundo nivel de atención. Metodología: estudio comparativo en pacientes con ERC del servicio de Nefrología, clasificados en tres grupos, dos de ellos en terapia de reemplazo renal (diálisis peritoneal y hemodiálisis) y uno sin terapia de reemplazo renal (prediálisis). Para la calidad del sueño se utilizó la escala de Pittsburgh, se incluyeron datos sociodemográficos y parámetros bioquímicos. Los datos se analizaron median- te comparación de frecuencias con Chi cuadrada, medias con t de Student y ANOVA de un factor. Resultados: se formaron tres grupos: hemodiálisis (n = 75), diálisis peritoneal (n = 58) y prediálisis (n = 71). La edad media fue de 53.5 años; la calidad subjetiva del sueño fue buena en el 48% del total y en el 54.9% de los pacientes en prediálisis (p < 0.05). Al aplicar la escala de Pittsburgh, el 80.4% del total y el 84.5% de los pacientes en diálisis reportaron una calidad de sueño mala. De las siete dimensiones evaluadas, dos fueron diferentes en los tres grupos (p < 0.05). Conclusiones: la percepción del paciente sobre la calidad del sueño habitualmente se sobreestima, lo que indica una adaptación a un sueño ineficiente. Debido a las características de estos pacientes es importante mantener un control de sus parámetros bioquímicos, que también tienen un impacto en la calidad del sueño.

Introduction: In patients with chronic kidney disease (CKD) and specifically with renal replacement therapy (RRT), their circadian cycle and consequently their sleep quality are affected. Objective: To evaluate the quality of sleep in patients with chronic kidney disease attends at the nephrology service. Methods: Comparative study in patients with chronic kidney disease from the nephrology service classified into three groups, two of them had renal replacement therapy (peritoneal dialysis and hemodialysis) and one without renal replacement therapy (predialysis). For the quality of sleep we used the Pittsburgh Scale, sociodemographic data and biochemical parameters were included. Comparison of frequencies with chi-square, means with Student's t and Anova of one factor. Results: Three groups were formed: hemodialysis (n = 75), peritoneal dialysis (n = 58) and predialysis (n = 71). The mean age was 53.5 years; the subjective quality of sleep was "good" in 48.0% of the total and in 54.9% of predialysis patients (p <0.05). When applying the Pittsburgh scale, 80.4% of the total and 84.5 of the dialysis patients reported a "poor" quality of sleep. Of the seven dimensions evaluated, two were different in the three groups (p < 0.05) Conclusions: The patient's perception of the quality of sleep is regularly overestimated, which indicates an adaptation to this dream habit. Due to the characteristics of these patients, it is important to keep a check on their biochemical parameters, which also have an impact on the quality of sleep.

The Effects of Total Knee Arthroplasty on Sleep Quality

@#Introduction:Symptomatic osteoarthritis is one of the most common indications for total knee arthroplasty (TKA) operations. Pain in every stage of the disease causes sleep disturbances in patients. The primary objective of this study was to evaluate the effect of TKA on the quality of sleep in patients with symptomatic osteoarthritis. Materials and Methods: This retrospective, descriptive study was performed on 80 patients diagnosed with symptomatic osteoarthritis who underwent TKA. The patients responded to the Pittsburgh Sleep Quality Index (PSQI), which is widely used to evaluate sleep quality. Additionally, the effects of demographic and clinical variables such as age, gender, body mass index, smoking and alcohol consumption were also evaluated before and after surgery. Results: There was no correlation between demographic variables and PSQI scores pre- and postoperatively. There was a decrease in sleep quality on the sixth postoperative week compared to the preoperative period however this difference was not statistically significant. On the other hand, there was a statistically significant difference between preoperative and postoperative sixth month PSQI scores. Mean values of overall sleep quality and daily function were significantly higher in the postoperative sixth compared to the preoperative period (p<0.001) Conclusion: Treatment of symptomatic OA with TKA will improve sleep quality in the long term.
