Clinical Work With Adult Male Incest Survivors: Therapeutic Themes And Perspectives, Kathryn B. Rosenberg Aug 2020

Clinical Work With Adult Male Incest Survivors: Therapeutic Themes And Perspectives, Kathryn B. Rosenberg

Doctoral Dissertations

For psychotherapists, encountering clients who have experienced sexual trauma or abuse is inevitable, whether or not the abuse is disclosed to the therapist; however, mental health professionals receive extremely limited (if any) training on how to identify or effectively support adult clients who are survivors of childhood sexual abuse (CSA). Many people who experienced CSA, especially those who identify as male, remain isolated and invisible in their suffering as adults even within therapeutic spaces, facing what feel like insurmountable barriers – both internal and external – to getting help. When sexual abuse is intrafamilial, these barriers are both amplified and …

Baybutt, Joshua Barton, Ellen M. Caparosa, Amanda M. Pattison, Jeff A. Rappaport, Jamin Roh, Tingting Zhan, Babar Bashir, Scott A Waldman, Adam E. Snook

Department of Pharmacology and Experimental Therapeutics Faculty Papers

BACKGROUND: Adenovirus serotype 5 (Ad5) is a commonly used viral vector for transient delivery of transgenes, primarily for vaccination against pathogen and tumor antigens. However, endemic infections with Ad5 produce virus-specific neutralizing antibodies (NAbs) that limit transgene delivery and constrain target-directed immunity following exposure to Ad5-based vaccines. Indeed, clinical trials have revealed the limitations that virus-specific NAbs impose on the efficacy of Ad5-based vaccines. In that context, the emerging focus on immunological approaches targeting cancer self-antigens or neoepitopes underscores the unmet therapeutic need for more efficacious vaccine vectors.

METHODS: Here, we evaluated the ability of a chimeric adenoviral vector (Ad5.F35) …

Plasmodium Impairs Antibacterial Innate Immunity To Systemic Infections In Part Through Hemozoin-Bound Bioactive Molecules., Christopher Lynn Harding Aug 2020

Plasmodium Impairs Antibacterial Innate Immunity To Systemic Infections In Part Through Hemozoin-Bound Bioactive Molecules., Christopher Lynn Harding

Electronic Theses and Dissertations

Despite efforts to decrease the global health burden of malaria, infections with Plasmodium species continue to cause over 200 million episodes of malaria each year which resulted in 405,000 deaths in 2018 [1]. One complication of malaria is increased susceptibility to invasive bacterial infections. Plasmodium infections impair host immunity to non-Typhoid Salmonella (NTS) through activities of heme oxygenase I (HO-I) )-induced release of immature granulocytes and myeloid cell-derived IL-10. Yet, it is not known if these mechanisms are specific to NTS. We show here, that Plasmodium yoelii 17XNL (Py) infected mice had impaired clearance of systemic Listeria monocytogenes (Lm) during …

Development, Expansion And Role Of Myeloid-Derived Suppressor Cells In Post-Sepsis Immune Suppression, Tuqa Alkhateeb Aug 2020

Development, Expansion And Role Of Myeloid-Derived Suppressor Cells In Post-Sepsis Immune Suppression, Tuqa Alkhateeb

Electronic Theses and Dissertations

Myeloid-derived suppressor cells (MDSCs) numbers increase significantly in sepsis and are associated with high mortality rates. These myeloid cell precursors promote immunosuppression, especially in the late (post sepsis) stage. However, the mechanisms that underlie MDSC expansion and programming are not completely understood. To investigate these mechanisms, we used a cecal-ligation and puncture (CLP) mouse model of polymicrobial sepsis that progresses from an early/acute proinflammatory phase to a late/chronic immunosuppressive phase. Previous studies in our laboratory showed that microRNA (miR)-21 and miR-181b elevate levels of the transcription factor nuclear factor 1 (NFI-A) that promotes MDSC expansion. We report here that miR-21 …

Department of Pathology and Laboratory Medicine

Schistosomiasis is rarely seen in Pakistan and is generally not very high on the list of differential diagnoses. However, it is an important cause of haematuria in certain endemic areas. It can affect multiple organs including the bladder, liver and lungs. We present a case of a young Pakistani male, travelling to and from Africa, who presented with complains of haematuria and suprapubic discomfort. Final pathologic diagnosis was urinary schistosomiasis (hematobium species). This case is particularly notable for the characteristic sago nodules identified on cystoscopy. It is important to consider schistosomiasis in the differential of haematuria in such scenarios as …

Dermatology Journals And The Impact Factor, Lawrence Charles Parish, W Clark Lambert

Department of Dermatology and Cutaneous Biology Faculty Papers

The noted informatics authority, Eugene Garfield (1925-2017), while working at the Johns Hopkins Medical Library, decided to assist medical librarians in selecting the publications to which they should subscribe. Not only at issue was the expense of subscribing and binding the periodicals, but there was also the physical space for shelving them. This was the birth of the Science Citation Index (SCI), the Impact Factor (IF), and the Institute for Scientific Information (ISI)in Philidelphia.

The role of the SCI has expanded over the years. Libraries may still continue to select journals on the basis of their IF, with many institutions …

Hyperammonaemia in children can lead to grave consequences in the form of cerebral oedema, severe neurological impairment and even death. In infants and children, common causes of hyperammonaemia include urea cycle disorders or organic acidaemias. Few studies have assessed the role of extracorporeal therapies in the management of hyperammonaemia in neonates and children. Moreover, consensus guidelines are lacking for the use of non-kidney replacement therapy (NKRT) and kidney replacement therapies (KRTs, including peritoneal dialysis, continuous KRT, haemodialysis and hybrid therapy) to manage hyperammonaemia in neonates and children. Prompt treatment with KRT and/or NKRT, the choice of which depends on the …

The current obesity epidemic faces a lack of mechanistic insights. It is known that the acute activity changes of a growing number of brain neurons rapidly alter feeding behaviour; however, how these changes translate to obesity development and the fundamental mechanism underlying brain neurons in controlling body weight remain elusive. Here, we show that chronic activation of hypothalamic arcuate GABAergic (GABA
