Validation of a Device for the Ambulatory Monitoring of Sleep Patterns: A Pilot Study on Parkinson's Disease

This study aims to validate an ambulatory circadian monitoring (ACM) device for the detection of sleep and wake states and apply it to the evaluation of sleep quality in patients with Parkinson disease (PD). A polysomnographic validation study was conducted on a group of patients with different sleep disorders in a preliminary phase, followed by a pilot study to apply this methodology to PD patients. The ACM device makes it possible to estimate the main sleep parameters very accurately, as demonstrated by: (a) the lack of significant differences between the mean values detected by PSG and ACM in time in bed (TIB), total sleep time (TST), sleep efficiency (SE), and time awake after sleep onset (WASO); (b) the slope of the correlation lines between the parameters estimated by the two procedures, very close to 1, which demonstrates the linearity of the predictions; (c) the low bias value in the estimates obtained through ACM. Sleep in PD is associated with lower distal skin temperature, efficiency and overall sleep time; greater WASO, activity during sleep and duration of naps and a worse circadian function index. In summary, the ACM device has proven to be clinically useful to evaluate sleep in an objective manner, thanks to the integrated management of different complementary variables, having advantages over conventional actigraphy. Introduction Sleep disorders constitute one of the most common non-motor symptoms of Parkinson's Disease (PD), with a prevalence ...

Authors: Voitey M, Bouiller K, Chirouze C, Fournier D, Bozon F, Klopfenstein T Abstract INTRODUCTION: Little is known about the functional symptoms associated with Lyme borreliosis (LB) in Europe. We aimed to assess functional symptoms associated with presumed LB and to compare patients with and without confirmed LB. MATERIALS AND METHODS: We performed a retrospective monocenter study. Patients consulting for presumed LB were included. RESULTS: Between November 2015 and June 2018, 355patients were included (mean age: 51years, 52% of women) of which 48had LB: erythema migrans (42%), early disseminated LB (50...

ConclusionsThese data challenge the current dogma linking FDG uptake to the glycolytic rate. They instead introduce a new model considering a strict link between the uptake of this glucose analog, H6PD reticular activity and oxidative damage in diabetes, at least under fasting condition.

We studied whether calcium-sensing receptor (CaSR)-mediated NLRP3 inflammasome activation in THP-1 macrophages elevates inflammation in LS14 preadipocytes, modeling deleterious AT cell crosstalk. THP-1 macrophages exposed to Cinacalcet (CaSR activator, 2 μM, 4 h) showed elevated proinflammatory marker and NLRP3 inflammaso...
