Sexual Violence And Sub-Saharan Migrants In Morocco: A Community-Based Participatory Assessment Using Respondent Driven Sampling, Ines Keygnaert, Abdessamad Dialmy, Altay Manço, Jeroen Keygnaert, Nicole Vettenburg, Kristien Roelens, Marleen Temmerman

Obstetrics and Gynaecology, East Africa

Background: The European Union contracted Morocco to regulate migration from so-called “transit migrants” from Morocco to Europe via the European Neighbourhood Policy. Yet, international organisations signal that human, asylum and refugee rights are not upheld in Morocco and that many sub-Saharan migrants suffer from ill-health and violence. Hence, our study aimed at 1) investigating the nature of violence that sub-Saharan migrants experience around and in Morocco, 2) assessing which determinants they perceive as decisive and 3) formulating prevention recommendations.

Methods: Applying Community-Based Participatory Research, we trained twelve sub-Saharan migrants as Community Researchers to conduct in-depth interviews with peers, using Respondent …

Currie, Therese Dowswell, Marleen Temmerman

Obstetrics and Gynaecology, East Africa

Background: Maternal mortality has declined by nearly half since 1990, but over a quarter million women still die every year of causes related to pregnancy and childbirth. Maternal-health related targets are falling short of the2015 Millennium Development Goals and a post-2015 Development Agenda is emerging. In connection with this, setting global research priorities for the next decade is now required.

Methods: We adapted the methods of the Child Health and Nutrition Research Initiative (CHNRI) to identify and set global research priorities for maternal and perinatal health for the period 2015 to 2025. Priority research questions were received from various international …

Newborn Care In Indonesia, Lao People’S Democratic Republic And The Philippines: A Comprehensive Needs Assessment, Els Duysburgh, Birgit Kerstens, Melissa Diaz, Vini Fardhdiani, Katherine Ann Reyes, Khamphong Phommachanh, Marleen Temmerman, Basil Rodriques, Nabila Zaka

Obstetrics and Gynaecology, East Africa

Background: Between 1990 and 2011, global neonatal mortality decline was slower than that of under-five mortality. As a result, the proportion of under-five deaths due to neonatal mortality increased. This increase is primarily a consequence of decreasing post-neonatal and child under-five mortality as a result of the typical focus of child survival programmes of the past two decades on diseases affecting children over four weeks of age. Newborns are lagging behind in improved child health outcomes. The aim of this study was to conduct a comprehensive, equity-focussed newborn care assessment and to explore options to improve newborn survival in Indonesia, …

Aortic Valve Reconstruction With Use Of Pericardial Leaflets In Adults With Bicuspid Aortic Valve Disease: Early And Midterm Outcomes, Meong Gun Song, Hyun Suk Yang, Jong Bum Choi, Je Kyoun Shin, Hyun Keun Chee, Jun Seok Kim

The Texas Heart Institute Journal

In this study, we retrospectively analyzed the outcomes of adults with bicuspid aortic valve (BAV) disease who underwent aortic valve reconstructive surgery (AVRS), consisting of replacement of the diseased BAV with 2 or 3 pericardial leaflets plus fixation of the sinotubular junction for accurate and constant leaflet coaptation. From December 2007 through April 2013, 135 consecutive patients (mean age, 49.2 ± 13.1 yr; 73.3% men) with symptomatic BAV disease underwent AVRS. Raphe was observed in 84 patients (62.2%), and the remaining 51 patients had pure BAV without raphe. A total of 122 patients (90.4%) underwent 3-leaflet reconstruction, and 13 (9.6%) …

Repeated Transradial Catheterization: Feasibility, Efficacy, And Safety, Marinos A Charalambous, Savvas S Constantinides, Michael A Talias, Elpidoforos S Soteriades, Christos P Christou

The Texas Heart Institute Journal

Transradial access is an alternative to the transfemoral approach in coronary interventions. It results in less access-site bleeding, shorter hospital stays, lower costs, and less pain for the patient. However, some authors have suggested that the transradial approach might lead to radial artery occlusion, which precludes repeated same-artery catheterizations. Using data from our center, we evaluated the feasibility, safety, and efficacy of repeated transradial catheterization.

We reviewed the 3,006 transradial catheterizations performed at our center from 2006 through 2009. Patients who had undergone at least one repeated transradial catheterization were identified, their cases monitored through 2012, and their baseline characteristics …

Formulating Effective And Accessible Population-Based Colorectal Cancer Screening Programs, Danielle Luffman

Independent Study Project (ISP) Collection

Colorectal cancer, a type of carcinoma originating in cells of the colon or rectum, continues to rank as the third most prevalent cancer worldwide with 1.36 million cases and the fourth most fatal with 693,881 deaths during 2012. In an attempt to alleviate the burden of colorectal cancer throughout society, governments and non-governmental organizations continue to implement population-based cancer screening programs. These programs, typically designed by a federal authority, offer free screening tests to a given population for a certain type of cancer on a routine basis. National systematic screening programs have effectively reduced the incidence of and mortality from …

Hyperthermia, Radiation And Chemotherapy: The Role Of Heat In Multidisciplinary Cancer Care., Mark Hurwitz, Md, Paul R. Stauffer

Department of Radiation Oncology Faculty Papers

The compelling biologic basis for combining hyperthermia with modern cancer therapies including radiation and chemotherapy was first appreciated nearly half a century ago. Hyperthermia complements radiation as conditions contributing to radio-resistance generally enhance sensitivity to heat and sensitizing effects occur through increased perfusion/tumor oxygenation and alteration of cellular death pathways. Chemosensitization with hyperthermia is dependent on the particular mechanism of effect for each agent with synergistic effects noted for several commonly used agents. Clinically, randomized trials have demonstrated benefit including survival with the addition of hyperthermia to radiation or chemotherapy in treatment of a wide range of malignancies. Improvements in …

Development And Characterization Of An Autologous Whole Cell Breast Cancer Vaccine, Samantha Leigh Kurtz

Graduate Theses and Dissertations

Approximately 40,000 women will die from breast cancer in the United States in 2014. About 90% of these deaths will be due to metastases, rather than the primary tumor and majority of metastases are due to the recurrence and progression of non-metastatic disease. Current adjuvant treatments, such as chemotherapy and radiation, have severe side effects and may result in overtreatment and drug resistance.

Since greater than 90% of patients are diagnosed between stages I-III and have minimal residual disease after treatment, there is an opportunity to treat patients with an autologous breast cancer vaccine. Autologous vaccines under development have a …

Treatment Updates Regarding Anaplastic Oligodendroglioma And Anaplastic Oligoastrocytoma, Khurshid Ahmed Khan, Ahmed Nadeem Abbasi, Nasir Ali

Department of Radiation Oncology

Anaplastic Oligodendroglioma / Anaplastic Oligoastrocytoma (AO/AOA) is a WHO Grade-III primary brain tumor. These tumors comprise about 5 - 10% of all gliomas, which make them the third most common primary brain tumors after glioblastoma multiforme and astrocytomas. For many years standard of treatment remained Maximum Safe Resection (MSR) followed by Radiotherapy (RT). These tumors have also been known to be sensitive to alkylator-based chemotherapy particularly the subset having 1p/19q co-deletion signature. There is robust data showing that these tumors are responsive to chemotherapy in recurrent or progressive setting. Recently, up front chemotherapy has been added to standard post-surgery RT. …

Government Efforts And Personal Opinion Explain The Medicalization Of Pregnancy And Childbirth Through Time In Lower Mustang, Nepal, Ruth Baker

Independent Study Project (ISP) Collection

The way that women approach pregnancy and childbirth in rural Nepal has seen an amazing change in the past twenty to thirty years. The medicalization of this entire process, from pre-­‐ to post-­‐natal care, comes with government efforts for the increased education of women about family planning, nutrition, hygiene, and the proposed benefits of institutional versus in-­‐home delivery. In 9 villages of Lower Mustang, interviews conducted with Government Health Post workers, Female Health Volunteers, and women of different ages sought to discern personal experience and opinion about pregnancy and childbirth from the perspective of both local women and those with …

The End Of An Era: The Cancer Stem Cell Hypothesis And Its Therapeutic Implications, Emily Paton

Independent Study Project (ISP) Collection

Cancer, a leading cause of death in many developed countries, has become a global health burden. Much of the drain on healthcare systems has resulted from the high cost and ineffectiveness of conventional cancer treatments, which often lead to cancer relapse or metastasis. The failures of chemotherapy, radiation, and surgery have been elucidated by the cancer stem cell (CSC) hypothesis, which postulates that a small percentage of tumor cells drive tumorigenesis. These cells can sustain cancer through their capacity to self-renew and differentiate into specialized tumor cell types, similar to how healthy stem cells maintain healthy tissues. Conventional cancer treatments …

Quantitative Neuropathological Assessment To Investigate Cerebral Multi-Morbidity, Johannes Attems, Janna H. Neltner, Peter T. Nelson

Pathology and Laboratory Medicine Faculty Publications

The aging brain is characterized by the simultaneous presence of multiple pathologies, and the prevalence of cerebral multi-morbidity increases with age. To understand the impact of each subtype of pathology and the combined effects of cerebral multi-morbidity on clinical signs and symptoms, large clinico-pathological correlative studies have been performed. However, such studies are often based on semi-quantitative assessment of neuropathological hallmark lesions. Here, we discuss some of the new methods for high-throughput quantitative neuropathological assessment. These methods combine increased quantitative rigor with the added technical capacity of computers and networked analyses. There are abundant new opportunities - with specific techniques …

Simplified Post Processing Of Cine Dense Cardiovascular Magnetic Resonance For Quantification Of Cardiac Mechanics, Jonathan D. Suever, Gregory J. Wehner, Christopher M. Haggerty, Linyuan Jing, Sean M. Hamlet, Cassi M. Binkley, Sage P. Kramer, Andrea C. Mattingly, David K. Powell, Kenneth C. Bilchick, Frederick H. Epstein, Brandon K. Fornwalt

Saha Cardiovascular Research Center Faculty Publications

BACKGROUND: Cardiovascular magnetic resonance using displacement encoding with stimulated echoes (DENSE) is capable of assessing advanced measures of cardiac mechanics such as strain and torsion. A potential hurdle to widespread clinical adoption of DENSE is the time required to manually segment the myocardium during post-processing of the images. To overcome this hurdle, we proposed a radical approach in which only three contours per image slice are required for post-processing (instead of the typical 30-40 contours per image slice). We hypothesized that peak left ventricular circumferential, longitudinal and radial strains and torsion could be accurately quantified using this simplified analysis.

Emerging Antiretroviral Drug Resistance In Sub-Saharan Africa: Novel Affordable Technologies Are Needed To Provide Resistance Testing For Individual And Public Health Benefits, Gert U. Van Zyl, Lisa M. Frenkel, Michael Chung, Wolfgang Preiser, John W. Mellors, Jean B. Nachega

Internal Medicine, East Africa

In industrialized countries, viral load monitoring and genotypic antiretroviral drug resistance testing (GART) play an important role in the selection of initial and subsequent combination antiretroviral therapy (cART) regimens. In contrast, resource constraints in Africa limit access to assays that could detect virologic failure, transmitted drug resistance (TDR) and acquired drug resistance to cART. This has adverse consequences for both individual and public health. Although the further roll-out of antiretrovirals for prevention, including preexposure prophylaxis (PrEP) and universal test and treat (UTT) strategies, could reduce HIV-1 incidence, these strategies may increase TDR [1,2]. Here, we present arguments that the scale …

The Omega-3 Fatty Acid Docosahexaenoic Acid Attenuates Organic Dust-Induced Airway Inflammation., Tara M. Nordgren, Taylor D. Friemel, Art J. Heires, Jill A. Poole, Todd A. Wyatt, Debra J. Romberger

Journal Articles: Pulmonary & Critical Care Med

Workers exposed to organic dusts from concentrated animal feeding operations (CAFOs) are at risk for developing airway inflammatory diseases. Available preventative and therapeutic measures for alleviating dust-induced lung disease are inadequate. Because omega-3 fatty acids can mitigate inflammatory processes, we aimed to determine whether nutritional supplementation with the omega-3 fatty acid docosahexaenoic acid (DHA) could reduce the airway inflammatory consequences of exposures to organic dust. Aqueous extracts of organic dusts from swine CAFOs (ODE) were utilized. In DHA-pretreated human bronchial epithelial cells, lung fibroblasts, monocyte cell cultures, and precision-cut murine lung slices, we found that DHA pretreatment dose-dependently decreased ODE-induced …

Surface Attachment Induces Pseudomonas Aeruginosa Virulence, Albert Siryaporn, Sherry L. Kuchma, George A. Ou2019toole, Zemer Gitai

Dartmouth Scholarship

Pseudomonas aeruginosa infects every type of host that has been examined by deploying multiple virulence factors. Previous studies of virulence regulation have largely focused on chemical cues, but P. aeruginosa may also respond to mechanical cues. Using a rapid imaging-based virulence assay, we demonstrate that P. aeruginosa activates virulence in response to attachment to a range of chemically distinct surfaces, suggesting that this bacterial species responds to mechanical properties of its substrates. Surface-activated virulence requires quorum sensing, but activating quorum sensing does not induce virulence without surface attachment. The activation of virulence by surfaces also requires the surface-exposed protein PilY1, …

The Emerging Roles Of Gprc5a In Diseases., Honglei Zhou, Isidore Rigoutsos

Computational Medicine Center Faculty Papers

The 'Retinoic Acid-Inducible G-protein-coupled receptors' or RAIG are a group comprising the four orphan receptors GPRC5A, GPRC5B, GPRC5C and GPRC5D. As the name implies, their expression is induced by retinoic acid but beyond that very little is known about their function. In recent years, one member, GPRC5A, has been receiving increasing attention as it was shown to play important roles in human cancers. As a matter of fact, dysregulation of GPRC5A has been associated with several cancers including lung cancer, breast cancer, colorectal cancer, and pancreatic cancer. Here we review the current state of knowledge about the heterogeneity and evolution …

Longer Gestation Among Children Born Full Term Influences Cognitive And Motor Development, Emma V. Espel, Laura M. Glynn, Curt A. Sandman, Elyssia Poggi Davis

Psychology Faculty Articles and Research

Children born preterm show persisting impairments in cognitive functioning, school achievement, and brain development. Most research has focused on implications of birth prior to 37 gestational weeks; however, the fetal central nervous system continues to make fundamental changes throughout gestation. Longer gestation is associated with reduced morbidity and mortality even among infants born during the period clinically defined as full term (37–41 gestational weeks). The implications of shortened gestation among term infants for neurodevelopment are poorly understood. The present study prospectively evaluates 232 mothers and their full term infants (50.4% male infants) at three time points across the first postnatal …
