Gut Feelings: A Literature Review On The Gut-Brain Axis And Its Potential Influence On Mood, Grace Johnson

University Honors Theses

In recent decades, research on the gut-brain axis has evolved due to an increasing interest in the connection between gut health and mental health. The gut-brain axis presents a new frontier of health for both medical professionals and psychologists as there is expanding evidence illustrating the comorbidity of gut disorders and mood disorders. Due to the complex nature of studying the gut-brain axis and the myriad of influences on mood disorders such as depression, research has yet to find significant results definitively tying the two together. Nonetheless, the current body of literature on the topic provides a promising outlook on …

Examining Health Care Utilization Among Adult Heart Disease Patients With Self-Reported Depressive Symptoms, Courtney R. Lockett

Walden Dissertations and Doctoral Studies

Health care costs are most commonly concentrated among small groups of high-cost patients, or high utilizers. Many of these patients receive unnecessary and ineffective care and often critical health care needs can go unmet, even when substantial care from multiple sources is received. Thus, there is a need to look into high utilizing patients for not only quality improvement but also effective resource allocation. The operational problem for health care administrators is managing resources and improving quality of care by targeting specific medical conditions that may be high utilizers of medical resources. The purpose of this study was to identify …

Doctor of Nursing Practice Final Manuscripts

Abstract

TITLE: Mental Health Screening For Low-Income Adolescents

BACKGROUND: Nearly 80% of adolescents in the United States will suffer from a mental illness and not receive evaluation or services. Children from low socio-economic backgrounds have an increased risk of mental health disorders which permeate into adulthood, leading to additional negative sequel and lower quality of life. Among adolescent mental health conditions, depression and anxiety are the most common. Literature has suggested provider intuition alone has low sensitivity and specificity for detecting mental illness and that screening tools are indicated.

Epidemiology Of Marijuana Use And Mental Health In The Context Of Changing Policies, David G. Harvey Ii

Walden Dissertations and Doctoral Studies

There is a growing body of evidence supporting the association between cannabis use and the development of mental health disorders, but few studies have addressed this association following the recent increase in marijuana legalization laws. Therefore, using the social ecological model and the self-medication theory of addiction as theoretical frameworks, the purpose of this retrospective database study was to assess the relationship between marijuana use and major depression and suicidal ideation in both adults and adolescents in 2008 and 2017. Data from the National Survey on Drug Use and Health were analyzed using logistic regression at the p < .05 threshold for statistical significance. Results demonstrated positive, statistically significant relationships between marijuana use and both major depression and suicidal ideation for both adults and adolescents in both 2008 and 2017. Further, the strengths of these relationships generally increased between 2008 and 2017, coincident with the increase in marijuana legalization laws. These findings provide empirical support to the association between cannabis use and the development of mental health disorders, and that the strength of these associations is increasing following the increase in marijuana legalization laws. This study has important implication for positive social change by identifying significant relationships between cannabis use and the development of mental health disorders and revealing that these relationships are strengthening over time, coincident with the increase in marijuana legalization laws.

The Role Of Self-Mutilation Behaviors Among Adolescents Who Are Depressed, Patricia Wilkins

Walden Dissertations and Doctoral Studies

Adolescents who are depressed may self-injure themselves. Common methods for non-suicidal self-injury are cutting and burning the skin of one’s own body. Multiple confounding factors of age, gender, race and socio-economic status could lead one to engage in intentional or unintentional self-mutilation acts. The current body of literature on adolescent mental health demonstrates limited understanding of how racial and ethnic identity factors contributes to depression, self-injurious behavior, and suicide. This quantitative study determined if there was a relationship between depression and prevalence of adolescent self-mutilation. The social ecological theory was used to study the intersection of social determinants of depression …

Flowers Or Flora?: Understanding The Effects Of Probiotics On Depression, Nicole Collopy

Senior Theses

The human gut is populated with hundreds of types of bacteria and fungi. In North America, both intestinal and mood disorders are prevalent, presenting health problems that challenge health care professionals and patients alike. A scholarly literature review was conducted to explore this important relationship.

The investigation of the literature revealed that there is an association between gut health disorders and mood disorders, mainly anxiety and depression. This is due to bi-directionality between the brain-gut pathways, meaning that gastrointestinal health may have an effect on mental health and vice versa.

This connection between gut and mood can have substantial implications …

Determining The Knowledge, Attitudes And Beliefs Of Healthcare Providers In Treating Non-Specific Acute And Chronic Back Pain, Stacey L. Kale

Doctor of Nursing Practice Scholarly Project

An Abstract of the Scholarly Project by

Stacey Kale

Managing back pain has become a public health and clinical challenge (Krein et al., 2016). Incidence of back pain related complaints requiring treatment in the US is estimated at 11.2% of the adult population (Dowell, Haegerich, & Chou, 2016). New research suggests that it is the most common pain problem (Pauline, 2016). It is the third most expensive health disorder and is exceeded only by cancer and heart disease. Many health care providers lack formal pain management education and training thus leaving them at risk for failing to properly manage patients …
