Investigating the Link Between Objective Sleep Metrics and Cerebral Small Vessel Disease in a Population‐Based Cohort

Journal of Sleep Research, EarlyView.
ABSTRACT Cerebral small vessel disease (CSVD), a disorder that affects the cerebral microvasculature, is commonly associated with aging and may contribute to dementia and stroke. Increasing evidence suggests a link between CSVD and sleep disturbances, but the association remains poorly understood.

Comparison of Actigraphy and Polysomnography in a Sleep Centre Cohort

Journal of Sleep Research, EarlyView.
MotionWatch 8 actigraphy correlated most strongly with PSG for total sleep time and showed modest group‐level bias, but wide individual limits of agreement precluded interchangeability. PLMS modified actigraphy‐PSG differences, while recording setting influenced actigraphy‐derived sleep continuity across home and inpatient recordings.

Trial Protocol: A Randomised, Controlled Cross‐Over Trial Evaluating the Digital Sleep Revolution Diagnostic‐Therapeutic Pathway for Obstructive Sleep Apnoea

Journal of Sleep Research, EarlyView.
ABSTRACT Obstructive sleep apnoea (OSA) is common, but current diagnostic pathways rely on single‐night assessment and the apnoea–hypopnoea index. Both are limited for assessment of variability and linking only weakly to symptoms, comorbidity and treatment response.

Desaturation of exhaled air in camels

Proceedings of the Royal Society of London. Series B. Biological Sciences, 1981
Abstract We have found that camels can reduce the water loss due to evaporation from the respiratory tract in two ways: (1) by decreasing the temperature of the exhaled air and (2) by removal of water vapour from this air, resulting in the exhalation of air at less than 100% relative humidity (r. h.).

A rare cause of desaturation in a ‘healthy child’

Journal of Cardiovascular Medicine, 2019
The isolated right superior caval vein draining into the left atrium is an extremely rare systemic venous malformation. Pediatricians must be aware of it especially in apparently healthy children with mild cyanosis in absence of respiratory symptoms and signs of cardiac malformation.

The desaturated panel D-15

Documenta Ophthalmologica, 1978
The Desaturated Panel D-15 is analogous in design to the standard Panel D-15 but of lower purity (chroma 2 Munsell); the test is more sensitive to mild and moderate losses in chromatic discrimination ability. Combination of the results of both tests allows recognition of several degrees of chromatic discrimination loss.

Comparative effect of a protein diet on the desaturation, elongation and simultaneous desaturation and elongation of linoleic acid

Lipids, 1972
AbstractThe effect of a protein diet on the biosynthesis of polyunsaturated fatty acids of the linoleic acid family was studied by incubation of rat liver microsomes with labeled linoleic acid. The incubation was performed in desaturating, elongating and desaturating‐elongating conditions.

Postoperative Oxygen Desaturation

2018
This case focuses on the benefits of using regional anesthesia vs. continuous administration of opioids by asking the question: What are the effects of regional anesthesia vs. continuous administration of opioids on respiratory function following general anesthesia for major surgery? This study demonstrated that narcotic analgesia is an important cause

Desaturation: diagnosis and treatment

Baillière's Clinical Anaesthesiology, 1993
The diagnosis and treatment of a sudden fall in oxygen transport by the haemoglobin of arterial blood (desaturation) requires a rapid, effective response during anaesthesia. This response has three important phases. The first phase consists of a rapid review of 'Airway, Breathing and Circulation' and provision of an increase in inspired oxygen.

Regulation of the Δ9 Desaturation

1977
Rat liver microsomes have the capacity to convert stearoyl CoA to oleyl CoA by an enzymatic reaction requiring both oxygen and the integrity of the NADH-linked microsomal electron transport chain of which Δ9 desaturase is the terminal component (Wilson et al., 1967).
