BACKGROUND It has previously been reported that short term submental stimulation can reduce the frequency of apnoea and improve sleep architecture in patients with obstructive sleep apnoea. The effects of submental stimulation during consecutive nights on apnoea or on daytime sleepiness have not, however, been studied. METHODS Patients with obstructive sleep apnoea were studied by polysomnogr...

This study examined the effects of two nights of total sleep deprivation (TSD) and two nights of recovery sleep on response inhibition. Thirty-eight young, healthy adults performed a Go-NoGo task at 14 : 00 after: (1) a normal night of sleep; (2) each of two consecutive nights of TSD; and (3) each of two consecutive nights of recovery sleep; they also performed the task at 05 : 00 during the fi...

When subjected to alternating quiet nights (32 dB) and noise nights (equivalent levels of 47 dB) a group of 14 subjects showed an average increase in the fraction of deep sleep of about 2.5% resulting from the traffic noise. Another group of 12 subjects whose noise nights were at 60 dB had an average of 4.6% increase in deep sleep during these nights. The number of wakings also increased for bo...

Abstract Background/Introduction Targets set by Public Health England (PHE) state that 90% of patients with atrial fibrillation (AF) are expected to receive anticoagulation 2029. In 2019/2020, across three London boroughs serving a population 770,000, the percentage AF at high risk stroke (CHA2DS2VASc>2) anticoagulated was below target PHE. addition, optimisation factors can significantl...

OBJECTIVE The objective of this study was to determine the safety, feasibility, and efficacy of a predictive hyperglycemia and hypoglycemia minimization (PHHM) system compared with predictive low-glucose insulin suspension (PLGS) alone in overnight glucose control. RESEARCH DESIGN AND METHODS A 42-night trial was conducted in 30 individuals with type 1 diabetes in the age range 15-45 years. P...

The use of metal-organic frameworks (MOFs) so far has largely relied on nonspecific binding interactions to host small molecular guests. We used long organic struts (approximately 2 nanometers) incorporating 34- and 36-membered macrocyclic polyethers as recognition modules in the construction of several crystalline primitive cubic frameworks that engage in specific binding in a way not observed...

Ca(2+)-selective microelectrodes with Simon's neutral carrier ETH 1001 are commercially available and have been widely used for the measurement of both extra- and intracellular calcium. The electrodes demonstrate high selectivity against other cations such as magnesium, sodium, and potassium. We report, however, that the ETH 1001-based microelectrode is a superior tetraphenylphosphonium (TPP+)-...
