REM-related obstructive sleep apnea (REM-OSA), as defined using revised apnea-hypopnea index (AHI) criteria, might represent a specific OSA phenotype. However, there is a lack of data on outcomes of treatment in this population. This study evaluated the effects of CPAP treatment over 12months on clinical outcomes for patients with the polysomnography phenotype of REM-OSA. We conducted a prospective observational study with the following inclusion criteria subjective sleepiness and diagnostic polysomnography demonstrating AHI ≥15 events/h, AHI <5 events/h, and ≥30min of REM sleep. Clinical outcomes assessed included Epworth Sleepiness Scale (ESS), psychomotor vigilanc test reaction time (PVT-RT), and CPAP adherence at baseline, 1, 3, 6, and 12 months; Functional Outcomes of Sleep Questionnaire (FOSQ) and Depression Anxiety Stress Scales (DASS-21) at baseline, 1, 3 and 12 months. The reason is the first 3 outcomes (ESS, PVT, adherence) were assessed at baseline, 1, 3, 6, and 12 months, while the next 2tients with moderate to severe REM-OSA is associated with reduced sleepiness and improved quality of life. The trial was registered in the Australian New Zealand Clinical Trials Registry ACTRN12620000576921, 18/05/2020 (retrospectively registered).

Positional therapy has been described as add-on therapy to a mandibular advancement device, but the efficacy of combination of positional therapy and positive airway pressure (PPAP) has not been documented. We have found PPAP therapy as an effective method of titration in patients with difficult to treat OSA (obstructive sleep apnea). This retrospective analysis was done in patients who had difficult to treat OSA, i.e., in whom titration in thesupine position was unacceptable with any PAP device (CPAP or bilevel PAP) and could only be successfully titrated with a PAP device in the lateral position. This study describes our experience of PPAP therapy. Baseline characteristics and polysomnography data of patients who were successfully titrated in supine v/s lateral positions were compared. Of 272 consecutive patients with OSA selected for analysis, 218 patients (191 and 27 with CPAP and bilevel PAP, respectively) could be successfully titrated in supine position. Further 54 (20%) patients in whom titration in supine position was unacceptable were titrated in lateral position. Patients titrated with PAP in the lateral position therapy group had higher BMI, higher neck and waist circumference, and lower awake sPO and nadir sPO during sleep, and spent more time in sleep with sPO < 90%. Combination of positional therapy and PAP device is an effective way of titration for difficult to treat OSA patients. It can be tried in patients who fail titration in supine position.

This effect allowed increasing the hatching of turkey poults by 6.73% and the hatchability of eggs, by 4.43%. At the same time, a statistically significant decrease in the key lipid peroxidation products in one-day-old turkey poults was observed. In particular, the content of isolated double bonds decreased 1.47-fold (p less then 0.01); diene conjugates, 1.67-fold (p less then 0.01); triene conjugates, 1.46-fold (p less then 0.05); oxidiene conjugates, 1.48-fold (p less then 0.01); and Schiff bases, 1.3-fold compared to the control. All the above-mentioned positively affected survivability in the experimental group, which appeared to be increased by 1% compared to the control.The dental remains of the porcupine from the Pleistocene deposits of the Lang Trang cave in northern Vietnam are described. Previously, this porcupine was identified as Hystrix brachyura Linnaeus, 1758 or H. indica Kerr, 1792. Based on the analysis of morphometric data, the systematic position of the form from Lang Trang and other large Pleistocene porcupines of Vietnam is determined as Hystrix kiangsenensis Wang, 1931.The dental remains of a large badger collected in 2020 from the Pleistocene deposits of the Lang Trang karstic cave in northern Vietnam are described. The molars М1 and М1 exhibit the features that are characteristic of Arctonyx collaris Cuvier, 1825. https://www.selleckchem.com/products/oxidopamine-hydrobromide.html At the same time, the length of M1 of the Lang Trang form exceeds that of modern greater hog badgers. Based on the size and structure of the teeth, it can be assigned to the subspecies A. c. rostratus Matthew et Granger, 1923 known from the Pleistocene of China and Southeast Asia.A dentary fragment of a great evening bat Ia io Thomas, 1902 found in 2020 in the Pleistocene deposits of the Lang Trang karstic cave in northern Vietnam is described. This rare species of large tropical bats now inhabits Nepal, eastern India, southern China, Thailand, Laos, and Vietnam and as a fossil is known from the Pleistocene of China. In Vietnam the fossil remains of this species have been discovered for the first time. By the total size and lower molar structure, the specimen from the Lang Trang cave is most similar to the subspecies Ia io peninsulata Soisook et al., 2017 that now occurs in southern Thailand.This paper describes the maxillaries of adult specimens of saber-toothed cats Homotherium crenatidens (Fabrini, 1890) and Megantereon sp. from the Taurida Cave (Crimea, Late Villafranchian; age, 1.8-1.5 Ma). We discuss the morphometric variability in the morphology of the upper carnassials and the length of the С1-Р3 diastema.Phagocytic and cytochemical parameters of peripheral blood leukocytes in adult and 1.5-month-old harp seal pups were studied. Phagocytic number, proportion of phagocytic leukocytes, and phagocytic activity, average number of absorbed latex particles per leukocyte, were determined. Differences between groups of seals by average values of these indicators have not been revealed. A correlation analysis revealed a significant relationship between the phagocytic activity of leukocytes and their glycogen content in adult seals (r = 0.89). Content of cationic bactericidal protein (CP) in leukocytes of adult animals was 10-12 times higher than in pups. Correlation of CP and eosinophil count in adults was high (r = 0.88). Adult had significantly more eosinophils than pups. The noted features can provide higher efficiency of phagocytosis and destruction of absorbed bacteria in adult seals as compared to pups, despite the high level of indicators of the first, absorbing, phase of phagocytosis in the latter.
