Our objectives were to analyze chronotypes, sleep and mood variables and to describe their association with some metabolic variables in this population. Methods An observational, cross-sectional study was performed. Adults with a diagnosis of T1DM were included. We evaluated chronotypes by the Morningness-Eveningness Questionnaires, sleep quality by Pittsburgh Sleep Quality Index (PSQI), excessive daytime sleepiness by Epworth Sleepiness Scale (ESS), symptoms of depression by Patient Health Questionnaire - 9 (PHQ-9) and emotional well-being by Emotional Well Being Index (IWHO-5). A few metabolic variables were included. Results Ninety-five patients participated. The mean age was 38 years old (range 18–70). The average body mass index (BMI) was 24.4 Kg/m2 (standard deviation [SD]: 4.6). Out of the total sample, 52.6% were males. The Intermediate chronotype was p...

Objetivos: Evaluar y comparar calidad de sueño y aspectos de la salud mental durante dos períodos diferentes de la pandemia por COVID-19, como así también analizar algunos cambios en hábitos/conductas. Materiales y métodos: Se realizó un estudio de corte transversal, a través de una encuesta anónima de la que participaron 998 personas. La misma se realizó en dos períodos de tiempo. El primer período comprendió de marzo a julio de 2020, el segundo período abarcó de marzo a julio 2021. El análisis consideró: información demográfica, calidad del sueño, síntomas depresivos y de ansiedad. Resultados: Al comparar la calidad de sueño durante los períodos 2020 versus el 2021, el porcentaje de malos dormidores pasó del el 51% al 59% en el segundo período. En cuanto a los síntomas depresivos pasó del 21,1 al 16,3% y el porcentaje de síntomas de ansiedad pasó del 59,5 al 47,6%. La mala calidad del sueño afectó a un número mayor de personas en el 2021 que en el 2020 mientras que el porcentaje de participantes con síntomas de ansiedad y de depresión disminuyó en el año 2021. En la segunda fase de la encuesta las personas modificaron algunos hábitos/conductas como ser: cambiaron horarios de rutina, adquirieron mascotas, compartieron más sus sueños y recordaban con mayor frecuencia los mismos. Este artículo contribuye a conocer diversos aspectos del sueño, los cambios de humor y modificaciones de hábitos/conductas que ocurrieron durante la pandemia en Argentina. Palabras clave: COVID-19-Parasomnias REM y NREM-Ansiedad-Depresión-Calidad del sueño.

Our aims were to report cases of the Kleine-Levin syndrome diagnosed in Buenos Aires, Argentina and to characterize the clinical presentation of these patients. We evaluated patients with Kleine-Levin syndrome according to the International Classification of Sleep Disorders. Psychiatric, physical and neurological symptoms were present. Some patients were investigated with brain Magnetic Resonance Imaging, Single Photon Emission Computed Tomography, electroencephalogram and some with polysomnography. Seven patients (2 female, 5 male), ages from 8 to 47 years (median 20.7 years) were included in the study. The duration of symptoms was 1.5-20 days with a mean of 8. The range of interval between episodes: 2.5-24 months, median=13. All seven patients had a history of hypersomnia (one of them post head injury); 5 reported hyperphagia a...

Conclusion: Intracranial masses can mimic ischemic events. Usually, these masses do not fit in vascular territories, but sometimes they coincide with vascular areas. Therefore, physicians should consider mass lesions in the differential diagnosis of ischemic stroke. Additionally physicians should keep in mind that these lesions may lead to primary tumors undiagnosed previously.

Positive correlation revealed between the blood LOO-and the cognitive decline in selected AD patients(r = +0.47; p b 0.05). Conclusion: Membrane lipid degradation product lipoperoxyradical (LOO-) seem to be involved in cognitive decline in Alzheimer's type of dementia.

To test the hypothesis that the prevalence and severity of sleep apnea is greater among patients with severe compared with moderate asthma and controls without asthma. Complete overnight home polysomnography was performed in 26 patients with severe asthma consecutively recruited to a difficult asthma program, 26 patients with moderate asthma, and 26 controls without asthma of similar age and body mass index. Flow rates and Juniper asthma control and quality of life questionnaires were also obtained.

El objetivo fue evaluar causas o motivos que fragmentan el sueño y los trastornos del sueño en diversas mujeres y trimestres de embarazo, comparándolos con los de las mujeres no embarazadas (MNE). Métodos: Estudio de corte transversal. Se utilizó encuestas anónimas, para evaluar motivos que fragmentan el sueño y cuestionarios específicos para evaluar trastornos del sueño. Resultados: Mujeres Embarazadas (ME)= 320. 1er Trimestre de embarazo (T): n = 106, 2do. T: n = 104, 3er T: n = 110. MNE: n = 304. Motivos más frecuentes que fragmentan el sueño, se presentó en ME y fueron: necesidad de orinar, posición incómoda, no poder rotar en la cama. Como trastornos del sueño encontramos: pesadillas 44 vs 4.9%; ronquidos con pausas: 31 vs 3%. Conclusión: En las mujeres embarazadas estudiadas, la mayoría de las causas o motivos analizados fragmentaron el sueño; tuvieron más desórdenes del sueño como pesadillas, trastornos r...
