Physiological Measurement Focus Issue

The Journal of Physiological Measurement is now accepting submissions in the focus issue: Automated Analysis of Arousals, Sleep and Sleep-Related Disorders Using Physiological Time Series. Please included updated results from the test dataset if you develop a new algorithm. Note that the scope does not confine you to the data and topic of this year's Challenge. The deadline is set for the end of February 2019.

New Toolkit Added: dSQI

The advent of telehealth applications and remote patient monitoring has led to an increasing need for continuous signal quality monitoring to ensure high diagnostic accuracy of the recordings. Cardiovascular diseases often manifest electrophysiological anomalies, therefore the electrocardiogram (ECG) is one of the most used signals for diagnostic applications. Various types of noise and artifacts are not uncommon in ECG recordings and assessing the quality of the signal is essential prior to any clinical interpretation. In this study, a dynamic signal quality index (dSQI) is introduced using a new time-frequency template-based approach.

New Database Added: RVMH1

Functional metrics of autonomic control of heart rate, including baroreflex sensitivity, have been shown to be strongly associated with cardiovascular risk. A decrease in baroreflex sensitivity with aging is hypothesized to represent a contributing causal factor in the etiology of primary hypertension. To assess baroreflex function in human subjects, two complementary methods to simulate the response in heart rate elicited by the Valsalva maneuver were developed and applied to data obtained from a cohort of healthy normal volunteers.

New Database Added: CVES

This database contains multimodal data from a large study investigating the effects of ischemic stroke on cerebral vasoregulation. The cross sectional study compared 60 subjects who suffered strokes, to 60 control subjects, collecting the following data for each patient across multiple days: transcranial doppler of cerebral arteries, 24-h blood pressure numerics, high resolution waveforms (ECG, blood pressure, CO2 and respiration) during various movement tasks, 24-h ECG, EMG, and accelerometer recordings, and gait pressure recordings during a walking test.

New Database Added: CULM

The Complex Upper-Limb Movements database contains hand trajectory data from ten subjects undergoing writing tasks, used to model motor primitives.

New Database Added: TPEHGT

The Term-Preterm ElectroHysteroGram DataSet with Tocogram (TPEHGT DS) contains 26 four-signal 30-min uterine EHG records, i.e., three EHG signals accompanied by a simultaneously recorded external tocogram measuring mechanical uterine activity (TOCO signal) of pregnant women, and another five 30-min uterine records (EHG signals and TOCO signal) of non-pregnant women.

Database Expanded: sleep-edfx

The sleep-edf database has been expanded to contain 197 whole-night PolySomnoGraphic sleep recordings, containing EEG, EOG, chin EMG, and event markers. Some records also contain respiration and body temperature.

New Database Added: BIDMC

This dataset contains signals and numerics extracted from the much larger MIMIC II matched waveform Database, along with manual breath annotations made from two annotators, using the impedance respiratory signal.

New Software: PCST

The PhysioNet Cardiovascular Signal Toolbox is an open-source modular program for calculating heart rate variability (HRV) implemented in Matlab with evidence-based algorithms and output formats. The Toolbox is compatible with 64-bit MATLAB on GNU/Linux, Mac OS X, and MS-Windows.

PhysioNet/CinC Challenge 2018

The 2018 PhysioNet/Computing in Cardiology Challenge is now open. This year's Challenge, "You Snooze, You Win", is focused on the problem of automatically detecting disturbances in a patient's sleep. Given a collection of physiological signals recorded during sleep, including EEG, ECG, and EMG, participants are invited to develop an algorithm to automatically identify arousal events, and will be scored based on how well their algorithm's results agree with those of expert human annotators.

New Database Added: SLEEPBRL

The database contains 32 records of non-contact sleep monitoring by a bioradar. The records are accompanied by results of sleep scoring, based on polysomnography according to the rules of the American Academy of Sleep Medicine.

Challenge Papers Available

All the papers from the Challenge along with their corresponding PDFs are now available. The links to the final source code representing their score will be posted soon.

New Database Added: CUILESS16

The Concept Unique Identifier (CUI)-less database contains a corpus of "CUI-less" concepts taken from the SemEval2015 Task 14 that have been assigned CUIs. The annotation process allows assignment of CUIS from any Unified Medical Language System (UMLS) semantic group and compositional normalization using more than one CUI per disease entity. Concepts are mapped to SNOMED CT as represented in the September 2016 version found in Unified Medical Language System (UMLS) 2016AB.
