ConclusionsCompared with the general population, the prevalence of elevated CVP and OSA is significant in this cohort of patients. Age, diabetes, and right lower extremity chronic venous insufficiency symptoms seem to be predictors of elevated CVP. Larger, population-based prevalence studies are needed to confirm these findings.

Authors: Ni W, Qi J, Liu L, Li S Abstract Pulse signals are widely used to evaluate the status of the human cardiovascular, respiratory, and circulatory systems. In the process of being collected, the signals are usually interfered by some factors, such as the spike noise and the poor-sensor-contact noise, which have severely affected the accuracy of the subsequent detection models. In recent years, some methods have been applied to processing the above noisy signals, such as dynamic time warping, empirical mode decomposition, autocorrelation, and cross-correlation. Effective as they are, those methods are complex ...

ConclusionsSeizure detection devices provide moderate or greater anxiety reduction among the majority of people with epilepsy and their caregivers, but current translatability into improvements in overall HR-QOL may be limited. Affordability and technological support are potential barriers to maximizing benefit equally among the epilepsy community. These considerations may be useful to help guide future device development and inform patient–clinician discussions on device usage and HR-QOL.

Benefit from nicotine consumption has been reported in adult patients with this disorder. For the first time, the...

This study investigated associations between screen-use (time and type) and cognition in children and tested the hypothesis that across all screen types, time spent on screens is negatively associated with cognition.MethodsThis study presents cross-sectional data from 11,875 US children aged 9–10 years. Exposures were self-reported daily recreational screen-use. The primary outcome was global cognition measured by the Youth NIH Toolbox®. Covariates included child education, pubertal development, parental education, household income, race/ethnicity, physical activity, and sleep duration.FindingsThe mean (SD) daily...

This study was a prospective, single cohort of consecutive adult patients undergoing MMA surgery for OSA at a single institution. The primary outcome measure was the development of nasal obstruction using the Nasal Obstruction Symptom Evaluation scale. Secondary outcomes included the rate of reintubation, submandibular duct function, development of neck infection, the need for subsequent surgical correction of nasal obstruction, and changes in the Apnea-Hypopnea Index.ResultsTwenty consecutive patients (85% male, mean age 47 years) were included in the study. Nasal Obstruction Symptom Evaluation scores improved in 88% of p...

This study examines the 12-month prevalence of mental disorders stratified by duration of sleep. Data were drawn from face-to-face interviews conducted in the National Epidemiologic Survey on Alcohol and Related Conditions III, a nationally representative survey of US adults (N = 36,309). There were 1893 (5.26%) participants who reported

Publication date: Available online 21 February 2020Source: Biocybernetics and Biomedical EngineeringAuthor(s): Ashima Khosla, Padmavati Khandnor, Trilok ChandAbstractElectroencephalogram (EEG) measures the neuronal activities in the form of electric currents that are generated due to the synchronized activity by a group of specialized pyramidal cells inside the brain. The study presents a brief comparison of various functional neuroimaging techniques, revealing the excellent neuroimaging capabilities of EEG signals such as high temporal resolution, inexpensiveness, portability and non-invasiveness as compared to the other ...
