Obstetrics and Gynaecology, East Africa

Background: Health service fees constitute substantial barriers for women seeking childbirth and postnatal care. In an effort to reduce health inequities, the government of Kenya in 2006 introduced the output-based approach (OBA), or voucher programme, to increase poor women’s access to quality Safe Motherhood services including postnatal care. To help improve service quality, OBA programmes purchase services on behalf of the poor and marginalised, with provider reimbursements for verified services. Kenya’s programme accredited health facilities in three districts as well as in two informal Nairobi settlements.

Methods: Postnatal care quality in voucher health facilities (n = 21) accredited in 2006 …

Obstetrics and Gynaecology, East Africa

Background: Galloping economic growth and reform in China in the past 30 years has led to dramatic social changes. Attitudes towards sex and sexual behaviour have changed, and premarital sex has become more acceptable. The methods of contraception have changed, and the use of highly effective or long-acting contraceptive methods tends to be decreasing, especially in urban areas. Abortion is commonly used to end unintended pregnancy. The aim of this study was to survey the current situation of induced abortions in selected hospitals in 30 provinces in China.

Methods: This cross-sectional study was conducted in 295 randomly selected hospitals in …


Quality At The Centre Of Universal Health Coverage, Howard L. Sobel, Dale Huntington, Marleen Temmerman Jan 2015

Quality At The Centre Of Universal Health Coverage, Howard L. Sobel, Dale Huntington, Marleen Temmerman

Obstetrics and Gynaecology, East Africa

The last decade of the MDG era witnessed substantial focus on reaching the bottom economic quintiles in low and middle income countries. However, the inordinate focus on reducing financial risk burden and increasing coverage without sufficient focus on expanding quality of services may account for slow progress of the MDGs in many countries. Human Resources for Health underlie quality and service delivery improvements, yet remains under-addressed in many national strategies to achieve Universal Health Coverage. Without adequate investments in improving and expanding health professional education, making and sustaining gains will be unlikely. The transition from the Millennium Development Goals (MDG) …


Determinants Of Method Switching Among Social Franchise Clients Who Discontinued The Use Of Intrauterine Contraceptive Device, Waqas Hameed, Syed Khurram Azmat, Moazzam Ali, Wajahat Hussain, Ghulam Mustafa, Muhammad Ishaque, Safdar Ali, Aftab Ahmed, Marleen Temmerman Jan 2015

Hypothyroidism And The Development Of Hypertension, Kaleb Short Jan 2015

Hypothyroidism And The Development Of Hypertension, Kaleb Short

All Graduate Theses, Dissertations, and Other Capstone Projects

Low thyroid hormone (TH) in adulthood is associated with increased risk of cardiovascular disease, including risk of hypertension. The Spontaneously Hypertensive Rat (SHR), exhibits alterations in thyroid function when compared to normotensive controls. Interestingly, inhibiting thyroid gland function before 4 weeks of age prevented hypertension in the SHR, indicating that TH is involved in the etiology of SHR hypertension. However, these studies utilized tail-cuff photoplethysmography (PPG), which is known to have stress-induced artifacts, and did not compare effects in the normotensive parent strain Wistar Kyoto (WKY) rat. Therefore, it is uncertain whether TH is responsible for an elevation in baseline …

The Fertility Problem Inventory And Infertility-Related Stress: A Case Study, Staci Leigh Born

All Graduate Theses, Dissertations, and Other Capstone Projects

More than seven million people of childbearing age in the United States experience infertility. For women, the experience of infertility is stressful. The Fertility Problem Inventory (FPI) has been used to quantitatively measure women's experience of infertility-related stress. However, the construct of infertility-related stress is poorly described in existing literature. The purpose of this case study was understand how women experience the FPI as a measure of infertility-related stress. To address this issue, women who are undergoing infertility treatment completed the FPI and participated in unstructured interviews. Archival documents were also retrieved to corroborate findings and satisfy saturation. Results indicate …


Acceptance And Uptake Of Influenza Vaccination By Health Care Workers, Leshonda Wallace Jan 2015

Acceptance And Uptake Of Influenza Vaccination By Health Care Workers, Leshonda Wallace

Walden Dissertations and Doctoral Studies

Influenza is a preventable infectious disease, against which vaccination is the primary means of protection. Health care workers (HCW) are among the most vulnerable to the illness and are likely to be sources of infection transmission while caring for patients. Circumstantial evidence suggests higher rates of vaccination coverage by HCW will coincide with a lower incidence of influenza transmission, yet a gap remains in the literature regarding governing health agencies' (i.e., licensing boards, medical and nursing associations) influence on the influenza vaccination practices of their constituents. Moreover, discrepancies exist between governing health agencies' and the National Vaccine Advisory Committee's recommendations …


Women's Perspectives On Adequacy Of Screening And Treatment For Postpartum Depression, Gloria Marcia Watson Jan 2015

Women's Perspectives On Adequacy Of Screening And Treatment For Postpartum Depression, Gloria Marcia Watson

Walden Dissertations and Doctoral Studies

Postpartum depression affects some 10% to 20% of mothers. Its impact on the health and well-being of mothers and their infants is well documented. If not identified and addressed early, it can result in emotional burden, costly hospitalization and treatment, and, at worst, suicide and or infanticide. Empowerment theory was the conceptual framework for this hermeneutic phenomenological study. The purpose was to understand the lived experiences of the screening and treatment processes of 10 women from New York City experiencing postpartum depression and their perceived adequacy of the treatment received. In-depth interviews were used to investigate participants' lived experiences of …

The Prospective Association Between Positive Psychological Well-Being And Diabetes, Julia K. Boehm, Claudia Trudel-Fitzgerald, Mika Kivimaki, Laura D. Kubzansky

Psychology Faculty Articles and Research

Objective: Positive psychological well-being has protective associations with cardiovascular outcomes, but no studies have considered its association with diabetes. This study investigated links between well-being and incident diabetes.

Methods: At study baseline (1991-1994), 7,800 middle-aged British men and women without diabetes indicated their life satisfaction, emotional vitality, and optimism. Diabetes status was determined by self-reported physician diagnosis and oral glucose tolerance test (screen detection) at baseline and through 2002-2004. Incident diabetes was defined by physician-diagnosed and screen-detected cases combined and separately. Logistic regression estimated the odds of developing diabetes controlling for relevant covariates (e.g., demographics, depressive symptoms). Models …

Targeted therapies and the consequent adoption of “personalized” oncology have achieved notable successes in some cancers; however, significant problems remain with this approach. Many targeted therapies are highly toxic, costs are extremely high, and most patients experience relapse after a few disease-free months. Relapses arise from genetic heterogeneity in tumors, which harbor therapy-resistant immortalized cells that have adopted alternate and compensatory pathways (i.e., pathways that are not reliant upon the same mechanisms as those which have been targeted). To address these limitations, an international task force of 180 scientists was assembled to explore the concept of a low-toxicity “broad-spectrum” therapeutic …


Bioactive Lipid Coating Of Bone Allografts Direct Engraftment And Fate Determination Of Bone Marrow-Derived Cells In Rat Gfp Chimeras, Anusuya Das, Claire E. Segar, Yihsuan Chu, Tiffany W. Wang, Yon Lin, Chunxi Yang, Roy C. Ogle Jan 2015

Bioactive Lipid Coating Of Bone Allografts Direct Engraftment And Fate Determination Of Bone Marrow-Derived Cells In Rat Gfp Chimeras, Anusuya Das, Claire E. Segar, Yihsuan Chu, Tiffany W. Wang, Yon Lin, Chunxi Yang, Roy C. Ogle

School of Medical Diagnostics & Translational Sciences Publications

Bone grafting procedures are performed to treat wounds incurred during wartime trauma, accidents, and tumor resections. Endogenous mechanisms of repair are often insufficient to ensure integration between host and donor bone and subsequent restoration of function. We investigated the role that bone marrow-derived cells play in bone regeneration and sought to increase their contributions by functionalizing bone allografts with bioactive lipid coatings. Polymer-coated allografts were used to locally deliver the immunomodulatory small molecule FTY720 in tibial defects created in rat bone marrow chimeras containing genetically-labeled bone marrow for monitoring cell origin and fate. Donor bone marrow contributed significantly to both …


Subdural Hematoma As A Consequence Of Epidural Anesthesia., Tracy M Bishop Do, Kareem S. Elsayed Ms, Kathleen E. Kane Md Jan 2015

Subdural Hematoma As A Consequence Of Epidural Anesthesia., Tracy M Bishop Do, Kareem S. Elsayed Ms, Kathleen E. Kane Md

Department of Emergency Medicine

Regional spinal and epidural anesthesia are used commonly in operative procedures. While the most frequent complication, postdural puncture headache (PDPH), is a clinically diagnosed positional headache that is usually self-limited, subdural hemorrhage (SDH) is a potentially fatal complication that cannot be missed. We report a case of an otherwise healthy female who presented with persistent positional headache and was ultimately found to have a large subdural hematoma with midline shift requiring surgical evacuation.

Human Metapneumovirus Is Capable Of Entering Cells By Fusion With Endosomal Membranes, Reagan G. Cox, Bernardon A. Mainou, Monika Johnson, Andrew K. Hastings, Jennifer E. Schuster, Terence S. Dermody, John V. Williams Jan 2015

Human Metapneumovirus Is Capable Of Entering Cells By Fusion With Endosomal Membranes, Reagan G. Cox, Bernardon A. Mainou, Monika Johnson, Andrew K. Hastings, Jennifer E. Schuster, Terence S. Dermody, John V. Williams

Manuscripts, Articles, Book Chapters and Other Papers

© 2015 Cox et al. Human metapneumovirus (HMPV), a member of the Paramyxoviridae family, is a leading cause of lower respiratory illness. Although receptor binding is thought to initiate fusion at the plasma membrane for paramyxoviruses, the entry mechanism for HMPV is largely uncharacterized. Here we sought to determine whether HMPV initiates fusion at the plasma membrane or following internalization. To study the HMPV entry process in human bronchial epithelial (BEAS-2B) cells, we used fluorescence microscopy, an R18-dequenching fusion assay, and developed a quantitative, fluorescence microscopy assay to follow virus binding, internalization, membrane fusion, and visualize the cellular site of …

Global Analysis Of Gene Expression And Projection Target Correlations In The Mouse Brain, Ahmed Fakhry, Tao Zeng, Hanchuan Peng, Shuiwang Ji Jan 2015

Global Analysis Of Gene Expression And Projection Target Correlations In The Mouse Brain, Ahmed Fakhry, Tao Zeng, Hanchuan Peng, Shuiwang Ji

Computer Science Faculty Publications

Recent studies have shown that projection targets in the mouse neocortex are correlated with their gene expression patterns. However, a brain-wide quantitative analysis of the relationship between voxel genetic composition and their projection targets is lacking to date. Here we extended those studies to perform a global, integrative analysis of gene expression and projection target correlations in the mouse brain. By using the Allen Brain Atlas data, we analyzed the relationship between gene expression and projection targets. We first visualized and clustered the two data sets separately and showed that they both exhibit strong spatial autocorrelation. Building upon this initial …

Electrical & Computer Engineering Faculty Publications

MR diffusion tensor imaging (DTI) technique together with traditional T1 or T2 weighted MRI scans supplies rich information sources for brain cancer diagnoses. These images form large-scale, high-dimensional data sets. Due to the fact that significant correlations exist among these images, we assume low-dimensional geometry data structures (manifolds) are embedded in the high-dimensional space. Those manifolds might be hidden from radiologists because it is challenging for human experts to interpret high-dimensional data. Identification of the manifold is a critical step for successfully analyzing multimodal MR images.

We have developed various manifold learning algorithms (Tran et al. 2011; Tran et al. …


Separating Autoimmune And Anti-Tumor Responses With Hsp70iq435a, James Mahon Jan 2015

Separating Autoimmune And Anti-Tumor Responses With Hsp70iq435a, James Mahon

Master's Theses

Vitiligo and melanoma are both melanocyte-derived diseases; vitiligo progresses through the autoimmune-targeted destruction of healthy melanocytes while melanoma results from uncontrolled proliferation of cancerous melanocytes. Treatment of vitiligo with HSP70iQ435A inhibits the DC-mediated auto-immune response against melanocytes in vitiligo mouse models; this raises the concern that treatment with this modified HSP may also inhibit natural anti-tumor responses against melanocyte-derived melanoma tumor cells.

We hypothesized that HSP70iQ435A prevents migration of melanocyte-antigen reactive T cells to the skin in a way that is mechanistically different from anti-tumor responses to melanoma and therefore would not have a negative effect on anti-tumor responses. We …

Electrical & Computer Engineering Faculty Publications

In this paper we report the set-up and results of the Multimodal Brain Tumor Image Segmentation Benchmark (BRATS) organized in conjunction with the MICCAI 2012 and 2013 conferences. Twenty state-of-the-art tumor segmentation algorithms were applied to a set of 65 multi-contrast MR scans of low-and high-grade glioma patients-manually annotated by up to four raters-and to 65 comparable scans generated using tumor image simulation software. Quantitative evaluations revealed considerable disagreement between the human raters in segmenting various tumor sub-regions (Dice scores in the range 74%-85%), illustrating the difficulty of this task. We found that different algorithms worked best for different sub-regions …

The Characterization Of A Putative Virulence Factor Expressed By Sneathia Amnii, Amy Sanford

Theses and Dissertations

Preterm birth, defined at birth before 37 weeks gestation, affects millions of newborns worldwide every year. Preterm birth is a leading cause of infant morbidity and mortality. One major cause of preterm birth is preterm premature rupture of membranes (PPROM), which can be triggered by bacterial infection and inflammation. A bacterial species that has been implicated in preterm birth and other obstetric complications is Sneathia amnii. The goals of this study were to observe cytopathogenic effects caused by S. amnii strain Sn35 and identify putative virulence factors causing those effects. Sn35 was able to adhere to, invade, and damage/kill …


Vitamin C: A Potential Regulator Of Inflammatory Response, Bassem M. Mohammed Jan 2015

Vitamin C: A Potential Regulator Of Inflammatory Response, Bassem M. Mohammed

Theses and Dissertations

Introduction: Neutrophils (PMNs) and Macrophages are the first responders recruited consecutively to the site of injury/inflammation. PMNs’ response/fate as well as macrophage reprogramming ultimately determine the course of resolution of inflammation. Physiologic wound healing has a significant inflammatory component. An exaggerated inflammation however is self-defeating leading to delayed healing. Parenteral vitamin C (VitC) attenuated inflammation in murine sepsis models and in patients with sepsis. However information about the mechanisms by which VitC regulates these events is limited.

Methods: Humanized mice lacking VitC synthesis capability (Gulo-/-) were used. VitC sufficient and deficient mice were challenged with sterile inflammation, or …
