Development of Software for Generating Synthetic Fetal Electrocardiograms

Some of the most common and fatal birth defects are those related to the heart. In adults, abnormal heart conditions are often identified through the use of an electrocardiogram (ECG). However, due to the presence of other signals and noise in the recording, fetal electrocardiography has not yet proven effective in diagnosing these defects. This paper develops a mathematical model of three-dimensional heart vector trajectories, which we use to generate synthetic maternal and fetal ECG signals. This dipole vector model simulates the electrical activity of the heart as a single time-varying vector originating at the center of the body. We use a system of ordinary differential equations whose numerical solution approximates the cardiac dipole vector. This system of equations is modified to account for noise, heart rate variability, and other physical and physiological considerations. Using this model, we have built a database of realistic, synthetic fECG signals using a variety of parameter values and noise levels. Currently, algorithms to extract the fetal signal from the fECG are tested on databases of clinical recordings. Our synthetic database allows further algorithm effectiveness testing to be performed on a broader set of data with knowledge of what the algorithm should output. We have also built a publicly accessible, interactive user interface for our model

Mathematically Modeling Fetal Electrocardiograms

Abstract Some of the most common and fatal birth defects are those related to the heart. In adults, possible heart conditions are often identified through the use of an electrocardiogram (ECG). However, due to the presence of other signals and noise in the recording, fetal eletrocardiography has not yet proven effective in diagnosing these defects. This paper develops a mathematical model of three-dimensional heart vector trajectories, which was used to generate synthetic maternal and fetal ECG signals. The dipole model is a useful simplification in which the electrical activity of the heart is viewed as a single time-varying vector originating at the center of the body. A system of ordinary differential equations whose numerical solution approximates this cardiac dipole vector was used. To simulate the cardiac activity of both mother and fetus, two sets of these equations must be implemented. When implementing this model, various physiological factors must be accounted for. After realistic maternal and fetal dipole vectors have been simulated, they are projected onto random unit vectors representing the lead axes of the fECG. Noise is then added to the signal. Using this model a database of realistic, synthetic fECG signals with different parameter values and noise levels has been built. Currently algorithms to extract the fetal signal from the fECG are tested on a database of clinical recordings. Our synthetic database will allow for algorithms to be tested on a broader set of data

Prevalence of Mental Health Disorder Symptoms and Rates of Help-seeking Among University-Enrolled, Black Men

Background. Black men in college represent a subgroup of emerging adults who are at increased risk of developing mental health disorders (MHDs), such as anxiety and depression. Such risk has been attributed to disproportionate experiences with everyday racial discrimination and high levels of psychological distress. Despite being at higher risk, university-enrolled, Black men are not utilizing mental health or health resources at optimal rates. The current evidence base describing prevalence of MHDs and health services utilization among Black men in college is limited. The present study addresses this by examining mental health prevalence among university-enrolled, Black men and their rates of health services utilization. Methods. We analyzed data (N ~ 2500) from a student survey, Spit for Science, a longitudinal, ongoing, research study at a mid-Atlantic, public university. Participants are given surveys in their freshman year and follow-up surveys every spring thereafter. Measures included: mental health disorders (depression and anxiety, as measured by the Symptom Checklist 90) and campus health service utilization (counseling center, health services, wellness center, and recreational sports). We conducted descriptive analyses to determine MHD symptom prevalence and utilization rates; Mann Whitney U tests to compare prevalence rates to White men and Black women; and, Chi-squared tests to compare rates of utilization among groups. Results. During their Freshman year, greater than 60% of students from each ethnic group reported at least one anxiety symptom and greater than 80% reported at least one depressive symptom. By senior year, reporting rates decreased significantly for Black men (49.6%) but remained high for White men (69.1%) and Black women (63%); p \u3c0.000. For depression, results were similar; however, only significant differences between Black men (72.7%) and Black women (87.1%); p\u3c0.000. Black men (20.4%), though reporting high levels of symptoms, still utilized counseling services at lower rates compared to White men (37.76%); p = 0.024. Conclusion. Findings suggest that Black men underutilize available campus health resources despite reporting one or more symptoms associated with anxiety and depression. Further research and prevention efforts are needed to improve help-seeking among this vulnerable population.https://scholarscompass.vcu.edu/gradposters/1077/thumbnail.jp

Experience of providing cultural safety in mental health to Aboriginal patients: A grounded theory study

The need for mental health clinicians to practice cultural safety is vital in ensuring meaningful care and in moving towards improving the mental health outcomes for Aboriginal people. The concept of cultural safety is particularly relevant to mental health professionals as it seeks to promote cultural integrity and the promotion of social justice, equity and respect. A substantive theory that explained the experience of providing cultural safety in mental health care to Aboriginal patients was developed using grounded theory methodology. Mental health professionals engaged in a social psychological process, called seeking solutions by navigating the labyrinth to overcome the experience of being unprepared. During this process participants moved from a state of being unprepared to one where they began to navigate the pathway of cultural safety. The findings of this research suggest health professionals have a limited understanding of the concept of cultural safety. The experience of providing cultural safety has not been adequately addressed by organizations, health services, governments, educational providers and policy makers. Health services, organizations and government agencies must work with Aboriginal people to progress strategies that inform and empower staff to practice cultural safety

VCU Gives Back

We propose the establishment of an organization wide series of community service events beginning at homecoming and culminating in April during National Volunteer Week with a large scale event, in an effort to bring a sense of unity among the students, faculty and staff within the organization while helping the communities surrounded by VCU

The Social and Cultural Context of Coping with Sickle Cell Disease: I. A Review of Biomedical and Psychosocial Issues

Sickle cell disease (SCD) is widely conceived in the United States as a group of blood disorders that principally affect African Americans. Although pain is its principal feature, strokes, lung problems, sepsis, anxiety, depression, impaired social functioning, and maladjustment at work are frequent concomitants. This article selectively reviews biomedical and psychosocial aspects of SCD related to pain assessment, medical treatment, genetic counseling, education, and employment. The strongest support exists for claims of social deficits among adolescents and depression and work-related problems among adults. The social context of SCD, including issues related to socioeconomic status (SES), urbanicity, ethnicity, cultural values, and racial stigmatization, are important to include in empirical assessments and theoretical analyses of the effects of SCD on children and their families. The adverse psychosocial functioning often described as an effect of SCD might indeed be a consequence of these factors acting alone or in concert with the strains of SCD.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/67048/2/10.1177_0095798499025003002.pd
