SMARTPHONE BASED SICKLE CELL DISEASE DETECTION AND ITS TREATMENT MONITORING FOR POINT-OF-CARE SETTINGSUnknown Date (has links)
The majority of Sickle Cell Disease (SCD) prevalence is found in Sub-Saharan Africa, where 80% of the world’s population who suffer from this disease are born. Due to a lack of diagnosis and early treatments, 50-90% of these children will die before they reach the age of five. Current methods used for diagnosing SCD are based on hemoglobin analysis such as capillary electrophoresis, ion-exchange high-performance liquid chromatography, and isoelectric focusing. They require expensive laboratory equipment and are not feasible in these low-resource countries. It is, therefore, imperative to develop an alternative and cost-effective method for diagnosing and monitoring of SCD. This thesis aims to address the development and evaluation of a smartphone-based optical setup for the detection of SCD. This innovative technique can potentially be applied for low cost and accurate diagnosis of SCD and improve disease management in resource-limited settings where the disease exhibits a high prevalence. This Point-of-Care (POC) based device offers the potential to improve SCD diagnosis and patient care by providing a portable and cost effective device that requires minimal training to operate and analyze. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2020. / FAU Electronic Theses and Dissertations Collection

Sickle Cell Disease Pain Burden and Quality of Life Among Black Children in MississippiCooper, LaQuita Nichelle 01 January 2018 (has links)
Acute and chronic pain is a common hallmark of sickle cell disease (SCD) in children and adolescents, which can have a profound effect on their quality of life (QOL). However, this relationship is not well quantified. The purpose of this quantitative study was to examine the relationship between SCD pain burden and QOL among Black children ages 8-17 in Mississippi with SCD. The secondary aim was to compare children and caregiver reports of SCD pain burden and QOL with SCD. The social ecological model was used to identify personal factors that influence SCD pain burden and QOL of children with SCD. Eighty-five children and caregiver pairs completed paper surveys on demographics, pain burden, and QOL. Hierarchical linear regression results indicated that increased child SCD pain burden was statistically associated with decreased child's QOL (P

Understanding Parents' Disease-Managing Strategies for Children With Sickle Cell DiseaseMackey, Michelle Noble 01 January 2019 (has links)
Sickle cell disease (SCD) is one of the most difficult and stressful chronic diseases for parents of afflicted children to manage. Managing SCD can be traumatic for parents particularly if they have no specific coping strategies for managing the disease or ensuring the child visits the doctor as scheduled. The use of certain coping strategies may affect the parents' and patients' perceptions of the illness and influence their decisions regarding treatment, which can have a lasting impact on their lives. Effective parental strategies such as positive thinking can aid in disease management, but there is limited research on the coping strategies used by parents of children with SCD specifically. The purpose of this phenomenological study, which was guided by Thompson and Gustafson's transactional stress and coping model, was to describe parents' coping strategies in managing their young child's SCD as it relates to use of health services. Data collection included one-to-one, open-ended interviews with 10 parents of children with SCD. Colaizzi's method of phenomenological data analysis was used to identify themes. Five themes emerged from data analysis and they are: parental methods of coping with SCD, participants' understanding of SCD, SCD family and support, managing SCD with hydration and medication, and experience accessing healthcare. These results indicated the participants' coping strategies varied according to their individual situations. Insight from this study could lead to positive social change by helping to identify specific coping strategies parents can use to better manage their child's disease and effectively access available health services.

Awareness and Attitudes of Young Nigerian Immigrants in the United States to Sickle Cell Screening and Premarital Genetic TestingAtolagbe, Timothy 01 January 2018 (has links)
The carrier frequency for sickle cell anemia among Nigerians, who account for a high percentage of African immigrants in the United States, is high, according to the World Health Organization. Even though sickle cell disease contributes $2.4 billion annually to U.S. health care expenditures, ascertaining the number of affected individuals in the U.S. is difficult because sickle cell is not a reportable genetic disease. However, according to the Census Bureau, the number of African immigrants continues to grow at a steady pace among the foreign-born immigrant population in the U.S. There is a lack of research on the contribution of the immigrant population to the sickle cell incidence and mortality rates in the U.S. The purpose of this study was to examine the level of awareness and attitude of young Nigerian immigrants in the United States to sickle cell screening and premarital genetic testing. The health belief model constituted the study's theoretical foundation. It was assumed that the level of awareness of sickle cell disease and the romantic choices among young Nigerian college and graduate students in the United States would have a direct relationship. A sample of undergraduate and graduate students of Nigerian origin completed an online survey developed for the study. The results from SPSS analyses indicated that even though this population sample has a high knowledge and awareness of sickle cell disease, they are non-committal about adapting and implementing such knowledge when making romantic choices. In order to continue to reduce the burden of sickle cell disease on healthcare delivery in the United States, public health education programs that address the adaptation and implementation of knowledge about sickle cell disease are needed.

The Effects of a Sickle Cell Disease Education Intervention Among College StudentsGuobadia, Edwin Ahunwan 01 January 2015 (has links)
Sickle cell disease (SCD) is a genetic disorder that affects millions of people worldwide. According to the Centers for Disease Control and Prevention, over 100,000 Americans have SCD, and more than 2 million Americans have a sickle cell trait (SCT). People with SCD are more likely than others to suffer premature mortality. Genetic screening is an important step in improving quality of life and increasing longevity for those with SCD. Early detection may lead to effective management of the disease and reduction of complicating factors. The purpose of this quasi-experimental study was to determine whether health education about SCD would impact college students' knowledge, attitudes, perceived risk, and intention to seek genetic screening and counseling in relation to the disease. The theoretical foundation for this study was the health belief model (HBM). This study involved 80 college students selected from a North Texas college. These students completed pre and post versions of an SCD questionnaire. Independent samples t tests were used to determine if there were significant differences in pre- and posttest scores of participants in both groups, and a MANOVA was used to determine differences among the scores of participants in the experimental group when grouped by age, gender, race, religiosity, and socioeconomic status. The results of this study showed that SCD health education improved the knowledge of and attitudes towards participants. Future research could explore barriers to seeking SCD screening and genetic counseling. Results of this study may further social change by encouraging the development of college-based health education efforts to increase awareness about SCD.

Sickle Cell Trait and Genetic CounselingSalmon Anderson, Tricia 01 January 2017 (has links)
Sickle cell trait (SCT) is a very prevalent disorder in the United States, especially among African Americans or people of African descent. However, even with the prevalence of the disorder, there are no standardized guidelines for providing patients with information about SCT and the implications of the disorder at physicals and well-check visits. The purpose of this evidence-based project was to increase awareness for African American patients 18-44 years old in the practice setting about SCT and to provide options for testing and genetic counseling. Kotter's contemporary change theory was used as a guide to implement the new practice approach. A quasi-experimental, single-group, pretest-posttest-only design was used to explore the relationship between providing consistent SCT education and the impact on the rate of SCT screening and genetic counseling. A total of 71 patients participated in the program. The analysis showed a significant (p < 0.001) mean difference of 18.16 points from the preintervention SCT and genetics test mean, which indicated that the intervention was successful in raising SCT and genetics knowledge scores among the target population. The results demonstrated that the implementation of SCT education in the practice setting can enhance social implications related to SCT awareness and opportunities for SCT testing and genetic counseling. The implementation of SCT clinical guidelines can help to increase awareness about SCT and improve the overall population health and reduce the financial burden affiliated with care of those with sickle cell disease and SCT complications.

Sphingolipid dysregulation in erythrocytes during sickle cell disease contributes to pro-inflammatory microparticle generation and subsequent inflammatory cell activationAwojoodu, Anthony O. 07 January 2016 (has links)
Sickle cell disease is a hereditary blood disorder caused by a point mutation in the gene encoding hemoglobin. This mutation causes hemoglobin molecules to polymerize during de-oxygenation of erythrocytes producing rod-shaped polymers that bend and distort the red blood cell membrane, making it more rigid and “sickled”. This sickling causes red blood cells to lose their flexibility and ability to navigate small capillaries and also enhances the production of pro-inflammatory membrane-derived microparticles, leading to chronic inflammation and many complications such as peripheral artery disease, stroke, myocardial infarction, vasculitis and even death. Sphingolipids are a class of lipids containing a backbone of sphingoid bases and are integral components of erythrocyte and microparticle membranes. Many of these lipids are known to mediate biological processes, but their expression, distribution and orientation in erythrocytes during sickle cell disease has never been explored. Sphingomyelin, the most abundant sphingolipid in the red blood cell membrane is hydrolyzed by sphingomyelinase to produce ceramide, which has been shown to alter membrane dynamics and enhance microvessel formation. Additionally, ceramide can be further metabolized to form sphingosine and sphingosine 1-phosphate, which is a bioactive ligand for 5 known G-protein coupled receptors present on most blood and vascular cells that modulates cell motility, proliferation, migration and phenotype. Prior to this work, it was not understood how sphingolipid metabolism contributes to vascular inflammation in sickle cell disease. Together, this body of work has elucidated key enzymatic and lipidomic alterations in sphingolipid metabolism (i.e. the activation of acid sphingomyelinase on red blood cells) that result in the production of sphingolipid-rich erythrocyte-derived microparticles, which enhance inflammatory cell activation. Our work has elucidated novel pharmacological targets to reduce microparticle generation and subsequent vascular inflammation in sickle cell disease.
