Uganda: Malaria, Sui Hnem

Global Public Health

Malaria is an infectious disease caused by mosquito bite. It is a major health problem in Uganda and is a major cause of mortality and morbidity. Pregnant women and children are the most infected groups in the country. The Ugandan government did their best to keep children and women healthy by providing clinics near the villages and advocating home treatment for malaria. Although, the government is very supportive in preventing and promoting the malaria, people did not seek healthcare as much as they should. The reason for not seeking healthcare was because they feel healthy, or the clinic had long …

Togo: Hiv/Aids, Brooke Einsweiler

Global Public Health

This brief describes the political structure, internal, and external challenges of Togo, Africa. It primarily focuses on the internal challenge of the high AIDS prevalence in the country and goes into detail on the epidemiology, identification, challenges, and suggestions regarding the disease. AIDS is an immunodeficiency virus that makes it hard for the host to fight off infections and illnesses. The virus is transmitted through direct contact with bodily fluid and is most commonly spread through unprotected sex. Men having sex with men are at the highest risk of contracting HIV/AIDS in this region. Pregnant women with HIV/AIDS are also …

Hiv/Aids: Nigeria, Lauren Tropinski

Global Issues in Public Health

Nigeria has one of the largest prevalence rates of HIV infections in Africa. HIV is a communicable disease that is transmitted by bodily fluids through unprotected sex, using contaminated needles, or mother to child. The most affected populations include heterosexuals who have unprotected sex, followed by sex workers, and men who have sex with men. People will experience three stages of HIV before the last stage referred to as AIDS. Rapid diagnostic tests are used to diagnose the disease. There is no cure for HIV/AIDS. However, people with HIV are given antiretrovirals to keep HIV at a low level throughout …

The Effect Of Ostomate-To-Ostomate Support On Psychosocial Adaptation To Stoma, Marjorie C. Summers

Doctor of Nursing Practice Projects

Approximately one million people in North America are living with an ostomy, and an additional 100,000 will undergo ostomy surgery annually. Persons living with ostomies, often referred to as ostomates, require specialized care and management to sustain physical health and quality of life. Fecal diversion ostomates, when compared to the general population, are more likely to experience psychological disturbance and higher levels of depression. These ostomates have reported increased loneliness, lowered self-esteem, decreased or absent libido, irritability, suicidal ideation, poor self-image, and symptoms of generalized anxiety disorder and social phobia. Being an ostomate has been associated with a reduction in …

Factors Associated With Viral Non-Suppression Among Adolescents Living With Hiv In Cambodia: A Cross-Sectional Study, Kolab Chhim, Gitau Mburu, Sovannary Tuot, Ratana Sopha, Vohith Khol, Pheak Chhoun, Siyan Yi

Background

Adolescents living with HIV on antiretroviral therapy (ART) have worse treatment adherence, viral suppression, and mortality rates compared to adults. This study investigated factors associated with viral non-suppression among adolescents living with HIV in Cambodia.

Methods

A cross-sectional study was conducted in August 2016 among 328 adolescents living with HIV aged 15–17 years who were randomly selected from 11 ART clinics in the capital city of Phnom Penh and 10 other provinces. Clinical and immunological data, including CD4 count and viral load, were obtained from medical records at ART clinics. Adolescents were categorized as having achieved viral suppression if …

Non-Insidious Large Joint Manifestation Of Severe Cachectic Rheumatoid Arthritis., Simcha Weissman, Mira Alsheikh, Khalil Kamar, Joshua Breslin, Anthony Khabut, Mohammad G Maruf

Touro College of Osteopathic Medicine (New York) Publications and Research

Rheumatoid arthritis (RA) is an autoimmune disorder in which constitutional symptoms typically occur before joint swelling becomes a true clinical phenomenon. Weight loss, although common, is generally mild in nature and occurs after long standing inflammation. While large joints do become inflamed, RA has a much stronger predilection for the small joints. Our case is a rarity in the fact that there was initial large joint swelling without long standing inflammation. Additionally, the weight loss was cachectic in nature and extreme. Furthermore, while extra-articular manifestations do commonly occur, spontaneous pneumothorax is certainly atypical. The content of this manuscript serves to …

Rwanda: Hiv/Aids, Alissa Anderson

Global Public Health

Rwanda is a small country in Africa. Rwanda has had many conflicts within its borders with wars, genocide, and disease. One of Rwanda’s current threats is HIV/AIDS. This disease is spreading through its population, and making it easier for other diseases; such as hepatitis and tuberculosis, to spread as well. Rwanda is a country that is putting into effect many efforts to decrease its HIV/AIDS population by means of education, campaigns, and treatments regarding the disease. In this article, I use peer reviewed and reliable articles to show the past and current issues that Rwanda has to face with the …

Interleukin-6 And Exercise; Early Evidence Of A Novel Myokine, Brendan Hogg Mr.

Graduate Student Theses, Dissertations, & Professional Papers

Interleukin-6 (IL-6) was first identified as a pleiotropic cytokine, with a host of body-wide functions. Cytokine functions are characterized by chronically elevated levels within various inflammatory states. In this regard, IL-6 is largely associated with the acute phase response to many stimuli and performs specific actions when produced from certain cell types. Accrued evidence indicates IL-6 release from skeletal muscle often includes myokine functions. Novel myokine functions are adaptive in nature, and as compared to inflammatory/cytokine roles, exhibit a transient time course. Following exercise plasma IL-6 peaks and returns to resting levels within 1-2 hours. In contrast, IL-6 is observed …

Cellular And Molecular Basis Of Equine Arteritis Virus Persistent Infection In The Stallion Reproductive Tract: Characterization Of Local Host-Pathogen Interactions Mediating Long-Term Viral Persistence, Mariano Carossino

Theses and Dissertations--Veterinary Science

Equine arteritis virus (EAV) has a global impact on the equine industry being the causative agent of equine viral arteritis (EVA), a reproductive, respiratory, and systemic disease of equids. A distinctive feature of EAV infection is that it establishes long-term persistent infection in the reproductive tract of stallions and is continuously shed in the semen (carrier state). Recent studies showed that long-term persistence is associated with a specific allele of the CXCL16 gene (CXCL16S). However, the cellular and molecular mechanisms underlying the establishment and maintenance of persistent infection are yet to be determined. The studies were undertaken herein …

Mbabazi, H. Wesley Perkins, Alexander C. Tsai, Sv Subramanian, Nicholas A. Christakis, David Bangsberg

OHSU-PSU School of Public Health Faculty Publications and Presentations

HIV testing is an essential part of treatment and prevention. Using population-based data from 1664 adults across eight villages in rural Uganda, we assessed individuals’ perception of the norm for HIV testing uptake in their village and compared it to the actual uptake norm. In addition, we examined how perception of the norm was associated with personal testing while adjusting for other factors. Although the majority of people had been tested for HIV across all villages, slightly more than half of men and women erroneously thought that the majority in their village had never been tested. They underestimated the prevalence …

Identifying A Novel Role For Fractalkine (Cx3cl1) In Memory Cd8(+) T Cell Accumulation In The Omentum Of Obesity-Associated Cancer Patients, Melissa J. Conroy, Stephen G. Maher, Ashanty M. Ashanty, Suzanne Doyle, Emma K. Foley, John V. Reynolds, Aideen Long, Joanne Lysaght

Articles

The omentum is enriched with pro-inflammatory effector memory CD8+ T cells in patients with the obesity-associated malignancy, esophagogastric adenocarcinoma (EAC) and we have identified the chemokine macrophage inflammatory protein-1alpha as a key player in their active migration to this inflamed tissue. More recently, others have established that subsets of memory CD8+ T cells can be classified based on their surface expression of CX3CR1; the specific receptor for the inflammatory chemokine fractalkine. CD8+ T cells expressing intermediate levels (CX3CR1INT) are defined as peripheral memory, those expressing the highest levels (CX3CR1HI) are effector memory/terminally differentiated and those lacking CX3CR1 (CX3CR1NEG) are classified …

Counterregulatory Effects Of Ptx3 On Inflammation And Cellular Aging, Aaron L. Slusher

Theses and Dissertations

Pentraxin 3 (PTX3) is a vital regulator of innate immune function that has been shown to counterregulate pro-inflammatory signaling and protect against the development of cardiovascular disease (CVD). Less is known about how PTX3 may mitigate against CVD risk by regulating the pro-inflammatory response at the cellular level. Therefore, this dissertation details four manuscripts which aimed to examine the capacity of PTX3 to regulate the innate immune response of peripheral blood mononuclear cells (PBMCs) isolated from healthy adults. Manuscript 1 examined the capacity of PTX3 to alter the inflammatory milieu following in vitro stimulation of isolated PBMCs with the pro-inflammatory …

Nanomedicine For Immunosuppressive Therapy: Achievements In Pre-Clinical Research, Hanan Al-Lawati, Hamidreza Montazeri Aliabadi, Behzad Sharif Makhmalzadeh, Afsaneh Lavasanifar

Pharmacy Faculty Articles and Research

Introduction: Immunosuppression is the mainstay therapy in organ transplantation and autoimmune diseases. The effective clinical application of immunosuppressive agents has suffered from the emergence of systemic immunosuppression and/or individual drug side effects. Nanotechnology approaches may be used to modify the mentioned shortcomings by enhancing the delivery of immunosuppressants to target cells of the immune system, thus reducing the required dose for function, and/or reducing drug distribution to non-target tissues.

Areas covered: We provide an overview on the development of nanotechnology products for the most commonly used immunosuppressive agents. At first, the rationale for the use of nanoparticles as …

Armstrong, Alix Ashare, Thomas Broughton, Li Wang, Dov Pechenick, Christopher M. Burns, Randolph J. Noelle, Matthew P. Vincenti, Roy A. Fava

Dartmouth Scholarship

In addition to activated T cells, the immune checkpoint inhibitor “V domain-containing Ig suppressor of T-cell activation” (VISTA) is expressed by myeloid cell types, including macrophages and neutrophils. The importance of VISTA expression by myeloid cells to antibody-induced arthritis and its potential for relevance in human disease was evaluated. Methods: VISTA was immunolocalized in normal and arthritic human synovial tissue sections and synovial tissue lysates were subjected to western blot analysis. The collagen antibody-induced arthritis model (CAIA) was performed with DBA/1 J mice treated with antibodies against VISTA and with VISTA-deficient mice (V-KO). Total mRNA from arthritic joints, spleens, and …

Shanmugam, +Several Additional Authors

Medicine Faculty Publications

Racial differences exist in the severity of systemic sclerosis (SSc). To enhance our knowledge about SSc in African Americans, we established a comprehensive clinical database from the largest multicenter cohort of African American SSc patients assembled to date (the Genome Research in African American Scleroderma Patients (GRASP) cohort).

African American SSc patients were enrolled retrospectively and prospectively over a 30-year period (1987–2016), from 18 academic centers throughout the United States. The cross-sectional prevalence of sociodemographic, clinical, and serological features was evaluated. Factors associated with clinically significant manifestations of SSc were assessed using multivariate logistic regression analyses.

The study population included …

Activation Des Éosinophiles Humains Par Des Nanoparticules, Denis Girard, Maxime Marion-Murphy

Rapports de recherche scientifique

L’économie du Canada, comme celle de bien d’autres pays industrialisés, bénéficie du développement des nanotechnologies dont le fort potentiel peut être exploité dans plusieurs secteurs industriels. Un nombre croissant d’entreprises québécoises de production de nanoparticules (NP) est d’ailleurs déjà implanté et tout porte à croire que d’autres emboîteront le pas dans les années à venir. Ce faisant, non seulement le nombre de travailleurs œuvrant dans la fabrication et la synthèse des NP augmentera sensiblement, mais également le nombre de ceux qui seront appelés à en manipuler et à en transformer dans les domaines des nanotechnologies en général. Une des conséquences …
