The authors studied indices of the activity of the hypophyseogonadal system under the conditions of single sleep deprivation of 24-36 h duration and in the period of recovery. Eleven healthy men aged 21 to 26 were recruited in the study. Two series of investigations were performed: I--the examinees were studied before, after 24 h sleep deprivation and after the first recovery night; II--the scheme of investigation was identical but it included electroauriculopuncture 5-6 h after the start of sleep deprivation. The 24 h sleep deprivation was accompanied by an increase in ACTH and LH secretion, a decrease in the levels of STH, prolactin, total androgens and progesterone in the examinees' blood. On the whole, electroauriculopuncture optimized the activity of the hypophyseogonadal system expressed in lesser changes in the secretion of the above hormones in response to sleep deprivation.

This primigravid pregnant woman had a new diagnosis of primary biliary cholangitis (PBC) that was treated with a combination of ursodeoxycholic acid (UDCA) and bezafibrate. Pregnancy may unmask underlying chronic hepatic disorders in susceptible women and, in some cases, the associated abnormalities of liver function or increased serum bile acids (hypercholanaemia) can result in significant fetal and maternal risk. Maternal pruritus, with associated sleep deprivation, may cause considerable distress.

Background: Sleep deprivation leads to decreased performance, alertness and degradation in the health status of a person. Often the person remains unaware of the reduced alertness and may end up taking inaccurate decisions. There was a need to study the sleep duration of college goers and to study the effect of total night-time sleep duration on daytime Electroencephalogram (EEG) characteristics.

Background: Sleep deprivation can lead to increased body weight and blood pressure (BP), but the latent effects of partial sleep deprivation related to required night sentry duties within a short-term period on cardiometabolic characteristic changes in military personnel are unclear.
Aim: To investigate the association between night sentry duty frequency in the past 3 months and cardiometabolic characteristics in armed forces personnel.
Methods: A total of 867 armed forces personnel who were aged 18-39 years and did not take any antihypertensive medications in Taiwan in 2020 were included.
Adequate and sufficient sleep is essential for good health, effective functioning, and well-being, yet recent trends show increasing sleep deprivation, especially among adolescents and young adults. General procrastination and bedtime procrastination understood as the tendency to delay going to bed without external pressure, may contribute to sleep deprivation and fatigue. This study investigated how individual differences in time perspective are related to sleep sufficiency and daytime fatigue, two different sleep outcomes.
