Fotoohinasab, Atiyeh; Hocking, Toby; Afghah, Fatemeh A greedy graph search algorithm based on changepoint analysis for automatic QRS complex detection Journal Article Computers in Biology and Medicine, 130 , 2021, ISBN: 104208. @article{Fotoohinasab2021, title = {A greedy graph search algorithm based on changepoint analysis for automatic QRS complex detection}, author = {Atiyeh Fotoohinasab and Toby Hocking and Fatemeh Afghah}, url = {https://doi.org/10.1016/j.compbiomed.2021.104208}, doi = {10.1016/j.compbiomed.2021.104208}, isbn = {104208}, year = {2021}, date = {2021-03-01}, journal = {Computers in Biology and Medicine}, volume = {130}, abstract = {The electrocardiogram (ECG) signal is the most widely used non-invasive tool for the investigation of cardiovascular diseases. Automatic delineation of ECG fiducial points, in particular the R-peak, serves as the basis for ECG processing and analysis. This study proposes a new method of ECG signal analysis by introducing a new class of graphical models based on optimal changepoint detection models, named the graph-constrained changepoint detection (GCCD) model. The GCCD model treats fiducial points delineation in the non-stationary ECG signal as a changepoint detection problem. The proposed model exploits the sparsity of changepoints to detect abrupt changes within the ECG signal; thereby, the R-peak detection task can be relaxed from any preprocessing step. In this novel approach, prior biological knowledge about the expected sequence of changes is incorporated into the model using the constraint graph, which can be defined manually or automatically. First, we define the constraint graph manually; then, we present a graph learning algorithm that can search for an optimal graph in a greedy scheme. Finally, we compare the manually defined graphs and learned graphs in terms of graph structure and detection accuracy. We evaluate the performance of the algorithm using the MIT-BIH Arrhythmia Database. The proposed model achieves an overall sensitivity of 99.64%, positive predictivity of 99.71%, and detection error rate of 0.19 for the manually defined constraint graph and overall sensitivity of 99.76%, positive predictivity of 99.68%, and detection error rate of 0.55 for the automatic learning constraint graph.}, keywords = {}, pubstate = {published}, tppubtype = {article} } The electrocardiogram (ECG) signal is the most widely used non-invasive tool for the investigation of cardiovascular diseases.

Changes include allowing patients to take home more doses of methadone and buprenorphine rather than coming to the clinic every day (for methadone) or weekly (for buprenorphine) and relaxed restrictions on telehealth delivery.

Design/methodology/approach: A questionnaire was administered to 199 individuals incarcerated in a Southwest county jail as part of a social-epidemiological exploration of converging comorbidities in incarcerated populations. Among 96 participants with complete ACEs data, the authors determined associations between individual ACEs items and a summative score with methamphetamine (meth), heroin, other opiates and cocaine use and binge drinking in the 30 days prior to incarceration using logistic regression. Findings: People who self-reported use of methamphetamine, heroin, other opiates or cocaine in the 30 days prior to incarceration had higher average ACEs scores. Methamphetamine use was significantly associated with living with anyone who served time in a correctional facility and with someone trying to make them touch sexually. Opiate use was significantly associated with living with anyone who was depressed, mentally ill or suicidal; living with anyone who used illegal street drugs or misused prescription medications; and if an adult touched them sexually. Binge drinking was significantly associated with having lived with someone who was a problem drinker or alcoholic. Social implications: The findings point to a need for research to understand differences between methamphetamine use and opiate use in relation to particular adverse experiences during childhood and a need for tailored intervention for people incarcerated in jail.
