Objective To examine the sleep characteristics in three cross-sectional populations: young, premenopausal and postmenopausal women, associations between sleep, menopause, mood cognitive performance. Study design Twenty-one (45–51 years), 29 (59–71 years) 11 young (20–26 years, using oral contraceptives) women were recruited. Polysomnography was used to measure objective quality. Subjective quality, sleepiness assessed questionnaires. Cognitive performance investigated by means of attentional...

Aims The aim was to validate the performance of a monitoring system consisting wrist-worn device and data management cloud service intended be used by medical professionals in detecting atrial fibrillation (AF). Methods Thirty adult patients diagnosed with AF alone or concomitant flutter were recruited. Continuous photoplethysmogram (PPG) intermittent 30 s Lead I electrocardiogram (ECG) recordings collected over 48 h. ECG measured four times day at prescheduled times, when notified due...

Abstract Wearable long-term monitoring applications are becoming more and popular in both the consumer medical market. In wearable ECG monitoring, data quality depends on properties of electrodes how they interface with skin. Dry do not require any action from user. They usually irritate skin, provide sufficiently high-quality for purposes during low-intensity user activity. We investigated prospective motion artifact–resistant dry electrode materials monitoring. The tested were (1) porous:...

This paper demonstrates the measurement of respiration waveform during sleep with a noncontact radar sensor. Instead measuring only rate, methods that allow monitoring absolute displacement were studied. Absolute can in theory be measured quadrature microwave Doppler sensor and using nonlinear demodulation as channel combining method. However, this paper, relative measures used reference. is first time longer data sets have been analyzed successfully consists whole-night recordings three...

Interplay between posterior parietal cortex (PPC) and ipsilateral primary motor (M1) is crucial during execution of movements. The purpose the study was to determine whether functional PPC–M1 connectivity in humans can be modulated by sensorimotor training. Seventeen participants performed a training task that involved tapping index finger synchrony rhythmic sequence. To explore differences modality, one group ( n = 8) learned visual other 9) auditory stimuli. Transcranial magnetic...

Lenses are always exposed to radiation in brain computed tomography (CT) scans. However, the lens dose can be reduced by excluding from scanning area optimising gantry tilt and scan length. The object of this study is retrospectively analyse if optimisation length have been adequate CT brain, prospectively effect radiographer training quality examinations. This was conducted two parts. In all, 329 CTs performed Tampere University Hospital 2017 2019 were revised retrospectively. prospective...

Objective In this prospective randomized, placebo-controlled and double-blind study, the objective was to investigate effects of estrogen–progestin treatment (EPT) on sleep in pre- postmenopausal women.

Purpose The purpose of this paper was to offer more reliable dry electrode materials for long-term measuring and determine how repeated machine washing affects the measured impedance surface resistance sample electrodes. aim manufacture electrodes that could be used measurement ECG. Skin friendly, metal sheet type, a solution. Design/methodology/approach In addition two conventional already in heart rate belts, authors prepared tested three different Three 20-mm-diameter were manufactured...

Aim: Computed tomography angiography (CTA) is currently the most reliable imaging technique for evaluating and planning treatment of atherosclerosis. The drawbacks are its low spatial resolution challenging manual measurements. purpose this study was to develop a semi-automatic method segment vessel walls, surrounding tissue, carotid artery lumen measure severity stenosis. Methods: In vivo contrast CTA images from eight patients undergoing endarterectomy were analyzed using tailored...

Current chronic limb threatening ischemia (CLTI) diagnostics require expensive equipment, using ionizing radiation or contrast agents, summative surrogate methods lacking in spatial information. Our aim is to develop and improve contactless, non-ionizing cost-effective diagnostic for CLTI assessment with high accuracy by utilizing dynamic thermal imaging the angiosome concept.Dynamic test protocol was suggested implemented a number of computational parameters. Pilot data measured from 3...

Slow wave sequences with individually defined amplitude criterion were selected manually from frontopolar sleep EEG of eight healthy control subjects and patients apnea syndrome. Healthy had clearly more time occupied by slow in all night sleep. Closer examination revealed that the difference amount sequence between groups was statistically significant only first NREM episode. In other words, episode, where pressure is supposed to be highest. The lower might reflect fragmented patients,...

This paper studies the effect of bipolar subdermal EEG lead placement on measurement sensitivity distributions. The electrodes were subdermally located skull a realistic human head and arranged in 5×5 matrix at apex cranial vault. effects studied by means half-sensitivity volume (HSV). results indicate that measurements focus accuracy specificity measurement; however, size half varies due to electrode location across one or more gyri, gray matter cerebrospinal fluid (CSF) thickness. study...

Collaboration through the internet has proven that it can lower cost of film productions and gain a significant amount visibility to them. In this paper we present an overview design technology first experiences Wreck A Movie (WAM), which is collaborative tool for online production.

Stability of bone splitting sternotomy is essential for normal healing after open cardiac surgery. Mechanical vibration transmittance may offer a means early detection separation (diastasis) in the and prevent further complications. This article describes technical implementation validation analysis-based prototype device built measuring sternal connectivity sternotomy.An in-house measurement system, device, consisting actuator, sensor, main controller signal acquisition unit was designed...
