Middle East Respiratory Syndrome: A Global Health Challenge, Lawrence O. Gostin, Daniel Lucey

Georgetown Law Faculty Publications and Other Works

Beginning in May 2015, Middle-East respiratory syndrome (MERS) experienced its first publicly reported “super-spreading” event in South Korea. By mid-June, more than 120 cases and 11 deaths in South Korea had been linked to a businessman returning from travel to Bahrain, United Arab Emirates, the Kingdom of Saudi Arabia and Qatar. Globally more than 1200 had been infected of whom more than 450 died—a high fatality rate of 37%.

What are the most effective legal, social, and public health responses to MERS and other emerging diseases? First, the World Health Organization’s International Health Regulations (IHR) did not effectively guide the …

Environmental and Occupational Health Faculty Publications

Background: Recently, the International Agency for Research on Cancer (IARC) Programme for the Evaluation of Carcinogenic Risks to Humans has been criticized for several of its evaluations, and also for the approach used to perform these evaluations. Some critics have claimed that failures of IARC Working Groups to recognize study weaknesses and biases of Working Group members have led to inappropriate classification of a number of agents as carcinogenic to humans.

Objectives: The authors of this Commentary are scientists from various disciplines relevant to the identification and hazard evaluation of human carcinogens. We examined criticisms of the IARC classification process …

Adipokine Levels During The First Or Early Second Trimester Of Pregnancy And Subsequent Risk Of Gestational Diabetes Mellitus: A Systematic Review, Wei Bao, Aileen Baecker, Yiqing Song, Michele Kiely, Simin Liu, Cuilin Zhang

Publications and Research

Objective—We aimed to systematically review available literature linking adipokines to gestational diabetes mellitus (GDM) for a comprehensive understanding of the roles of adipokines in the development of GDM.

Methods—We searched PubMed/MEDLINE and EMBASE databases for published studies on adipokines and GDM through October 21, 2014. We included articles if they had a prospective study design (i.e., blood samples for adipokines measurement were collected before GDM diagnosis). Random-effects models were used to pool the weighted mean differences comparing levels of adipokines between GDM cases and non-GDM controls.

Results—Of 1,523 potentially relevant articles, we included 25 prospective studies relating …

Penile Microbiota And Female Partner Bacterial Vaginosis In Rakai, Uganda, Cindy M. Liu, Bruce A. Hungate, Aaron A.R. Tobian, Jacques Ravel, Lance B. Price, +8 Additional Authors

Environmental and Occupational Health Faculty Publications

Bacterial vaginosis (BV) is a common vaginal bacterial imbalance associated with risk for HIV and poor gynecologic and obstetric outcomes. Male circumcision reduces BV-associated bacteria on the penis and decreases BV in female partners, but the link between penile microbiota and female partner BV is not well understood. We tested the hypothesis that having a female partner with BV increases BV-associated bacteria in uncircumcised men. We characterized penile microbiota composition and density (i.e., the quantity of bacteria per swab) by broad-coverage 16S rRNA gene-based sequencing and quantitative PCR (qPCR) in 165 uncircumcised men from Rakai, Uganda. Associations between penile community …

Kaolin was then given to mice as food supplements and …

Examining The Toxicity, Exposure, And Regulatory Approach To Potential Human Health Risks Of The Algal Toxin Domoic Acid, Thomas H. Angus

Graduate Doctoral Dissertations

Domoic acid is a neurotoxin produced by the marine diatom genus Pseudo-nitzschia and causes cell death primarily in the area of the brain responsible for long-term memory. The resulting severe illness has been termed amnesic shellfish poisoning. Domoic acid accumulates in shellfish and planktivorous fish that consume Pseudo-nitzschia, resulting in exposure to humans through consumption of planktivorous seafood. A regulatory standard in seafood was developed shortly after its discovery in 1987 to protect against acute effects. This regulatory standard has not been revised despite significant recent data in the scientific literature.

This dissertation is divided into four sections: (1) …

Syncing Umbanda And Science (Sus): Using Umbanda’S Holistic Healing Methods To Increase Access To Healthcare, Alex E. Rosenthal

Undergraduate Theses—Unrestricted

In 1988, after the 1985 termination of the military dictatorship in Brazil, the constitution was rewritten to guarantee individual rights to all citizens of Brazil. Among the various other rights that the new constitution protected, anyone in Brazil was granted the right to government-funded healthcare under the regulation of the Unified Healthcare System, SUS. Because of structural inequalities in Brazil as well as the rise of privatized healthcare, equal access to healthcare is not a reality in modern-day Brazil. Many citizens who live in the periphery are limited to understaffed and underfunded primary health centers.

This monograph explores the healing …

disClosure: A Journal of Social Theory

I combine fieldwork photography and ethnographic documentation of gold mining in Madre de Dios, Peru, to examine the localized material, social, environmental, and health outcomes of the global gold boom. This 'theoretical photo essay’ examines how local and global forces coalesce around gold mining and influence peoples and environments in Western Amazonia. I use embodiment theory in anthropology, ecological economics, and theories of underdevelopment to understand local consequences of the global gold trade and to elucidate how opulence and the machinations of capital accumulation in economic centers of the world occur at the expense of human lives and environments in …

Tonb Not Directly Related To Efflux Of Antibiotics In E. Coli, Amber Gombash

Honors Projects

Studies in Pseudomonas aeruginosa have suggested that the TonB energy transduction system directly contributes to efflux-mediated antibiotic resistance, ostensibly by energizing one or more efflux systems. We have found ∆tonB strains of Escherichia coli to similarly be more sensitive to certain antibiotics relative to wild-type strains. To test the hypothesis that this enhanced sensitivity involved the energization of efflux systems, sensitivity patterns for a variety of antibiotics were evaluated using a set of strains differentially lacking genes encoding the Acr efflux system, the universal outer membrane efflux portal TolC, and TonB. No correlation was evident between the resistance phenotypes of …
