Expected accuracy of proximal and distal temperature estimated by wireless sensors, in relation to their number and position on the skin

Longato E, Garrido M, Saccardo D, Montesinos Guevara C, Mani A, Bolognesi M, Amodio P, Facchinetti A, Sparacino G, Montagnese S. PlosOne A popular method to estimate proximal/distal temperature (TPROX and TDIST) consists in calculating a weighted average of nine wireless sensors placed on pre-defined skin locations. Specifically, TPROX is derived from five sensors placed […]

Identifying pathways modulating sleep duration: from genomics to transcriptomics

Allebrandt K, Teder-Laving M, Cusumano P, Frishman G, Levandovski R, Ruepp A, Hidalgo M, Costa R, Metspalu A, Roenneberg T, de Pittà C. Scientific Reports Recognizing that insights into the modulation of sleep duration can emerge by exploring the functional relationships among genes, we used this strategy to explore the genome-wide association results for […]

Sleep-Wake Profile in Dementia with Lewy Bodies, Alzheimer’s Disease, and Normal Aging

Cagnin A, Fragiacomo F, Camporese G, Turco M, Bussè C, Ermani M, Montagnese S. Journal of Alzheimers Disease BACKGROUND: Alterations of the sleep-wake cycle are common features of neurodegenerative dementia. OBJECTIVES: To study differences in sleep-wake profiles in dementia with Lewy bodies (DLB), Alzheimer’s disease (AD), and healthy controls. METHODS: 30 DLB and 32 AD patients, […]

Vigilance and wake EEG architecture in simulated hyperammonaemia: a pilot study on the effects of L-Ornithine-L-Aspartate (LOLA) and caffeine

Garrido M, Skorucak J, Raduazzo D, Turco M, Spinelli G, Angeli P, Amodio P, Achermann P, Montagnese S. Metabolic Brain Disease Hyperammonaemia/mild hepatic encephalopathy (HE) can be simulated by the oral administration of a so-called amino acid challenge (AAC). This study sought to assess the effects of the AAC alone and in combination with either […]

Assessment of 6-sulfatoxymelatonin rhythms and melatonin response to light in disease states: lessons from cirrhosis.

Montagnese S, Middleton B, Corrias M, Mani AR, Skene DJ, Morgan MY. Chronobiology International Abstract Circadian rhythmicity and non-visual sensitivity to light can be assessed, in healthy subjects, by measuring the rhythm of the urinary melatonin metabolite 6-sulphatoxymelatonin (aMT6s) and by determining the response of plasma melatonin to nocturnal retinal light exposure, respectively. However, the […]

Acute hyperammonaemia induces a sustained decrease in vigilance, which is modulated by caffeine.

Casula EP, Bisiacchi PS, Corrias M, Schiff S, Merkel C, Amodio P, Montagnese S. Metabolic Brain Disease Abstract Hyperammonaemia is observed after prolonged, intense exercise, or in patients with hepatic failure. In the latter, it is associated with a set of neurological and psychiatric abnormalities termed hepatic encephalopathy. THE AIMS OF OUR STUDY WERE: 1. […]

Sleep and circadian rhythms in hospitalized patients with decompensated cirrhosis: effect of light therapy.

De Rui M, Middleton B, Sticca A, Gatta A, Amodio P, Skene DJ, Montagnese S. Neurochemistry Research Abstract Patients with liver cirrhosis often exhibit sleep-wake abnormalities, which are, at least to some extent, circadian in origin. A relatively novel non-pharmacological approach to circadian disruption is appropriately timed bright light therapy. The aims of this pilot […]

The influence of environmental factors on sleep quality in hospitalized medical patients.

Turco M, Corrias M, Chiaromanni F, Bano M, Salamanca M, Caccin L, Merkel C, Amodio P, Romualdi C, De Pittà C, Costa R, Montagnese S. Chronobiology International The assessment of diurnal preference, or the preferred timing of sleep and activity, is generally based on comprehensive questionnaires such as the Horne-Östberg (HÖ). The aim of the […]

The influence of environmental factors on sleep quality in hospitalized medical patients

Bano M, Chiaromanni F, Corrias M, Turco M, De Rui , Amodio P, Merkel C, Gatta A, Mazzotta G, Costa R, Montagnese S. Frontiers in Neurology INTRODUCTION: Sleep-wake disturbances are common in hospitalized patients but few studies have assessed them systematically. The aim of the present study was to assess sleep quality in a group […]

Induced hyperammonemia may compromise the ability to generate restful sleep in patients with cirrhosis.

Bersagliere A, Raduazzo ID, Nardi M, Schiff S, Gatta A, Amodio P, Achermann P, Montagnese S. Hepatology Abstract In patients with cirrhosis, hyperammonemia and hepatic encephalopathy are common after gastrointestinal bleeding and can be simulated by an amino acid challenge (AAC), or the administration of a mixture of amino acids mimicking the composition of hemoglobin.
