The Remains Of The Establishment Clause, Ira C. Lupu, Robert W. Tuttle

UC Law Journal

The very first words of the Bill of Rights mark religion as constitutionally distinctive. Congress may not enact laws respecting an establishment of religion—in particular, acts of worship, religious instruction, or proselytizing. A pluralist, liberal democracy requires separation of civil government from these distinctively religious activities. From the middle of the twentieth century until Justice O’Connor’s retirement in 2005, the Supreme Court energetically animated that principle of distinctiveness. In a series of decisions in the last decade, however, the Court has upended its longstanding approach to what is distinctive about religion in constitutional law. Notably, this process of change has …

School of Dentistry Faculty Research and Publications

Objective:

Black communities have disproportionately experienced adverse health effects from the COVID-19 pandemic while simultaneously having less vaccination access and decreased vaccine utilization. As such, predictors of vaccination uptake within Black communities are a public health imperative. Black Americans from socio-geographic regions associated with health inequities (e.g., Appalachia), including vaccination disparities, represent an intersection of racial, economic, and ethnic social identities. To better understand the preventive health needs of Black communities in Appalachia and elsewhere, this study examined psychosocial predictors of vaccination intention or behavior.

Method:

Adults (n = 336) identifying as Black or African American from West …

Prospective Role Of Cefiderocol In The Management Of Carbapenem-Resistant Acinetobacter Baumannii Infections: Review Of The Evidence, Marin Kollef, Herve Dupont, David E Greenberg, Pierluigi Viale, Roger Echols, Yoshinori Yamano, David P Nicolau

2020-Current year OA Pubs

Carbapenem-resistant Acinetobacter baumannii (CRAB) has been classified by the World Health Organization as being in the critical category of pathogens requiring urgent new antibiotic treatment options. Cefiderocol, the first approved siderophore cephalosporin, was designed for the treatment of carbapenem-resistant Gram-negative pathogens, particularly the non-fermenting species A. baumannii and Pseudomonas aeruginosa. Cefiderocol is mostly stable against hydrolysis by serine β-lactamases and metallo-β-lactamases, which are leading causes of carbapenem resistance. This review collates the available evidence on the in vitro activity, pharmacokinetics/pharmacodynamics, and efficacy and safety of cefiderocol, and outlines its current role in the management of CRAB infections. In vitro surveillance …

T-Cell Receptor Beta Variable Gene Polymorphism Predicts Immune-Related Adverse Events During Checkpoint Blockade Immunotherapy, Bettzy Stephen, Joud Hajjar, Shrutii Sarda, Dzifa Yawa Duose, Jeffrey M Conroy, Carl Morrison, Anas Alshawa, Mingxuan Xu, Abdulrazzak Zarifa, Sapna P Patel, Ying Yuan, Evan Kwiatkowski, Linghua Wang, Jordi Rodon Ahnert, Siqing Fu, Funda Meric-Bernstam, Geoffrey M Lowman, Timothy Looney, Aung Naing

Faculty, Staff and Students Publications

BACKGROUND: Immune checkpoint inhibitors have revolutionized cancer treatment. However, they are associated with a unique spectrum of side effects, called immune-related adverse events (irAEs), which can cause significant morbidity and quickly progress to severe or life-threatening events if not treated promptly. Identifying predictive biomarkers for irAEs before immunotherapy initiation is therefore a critical area of research. Polymorphisms within the T-cell receptor beta (TCRB) variable (TRBV) gene have been implicated in autoimmune disease and may be mechanistically linked to irAEs. However, the repetitive nature of the TCRB locus and incomplete genome assembly has hampered the evaluation of TRBV polymorphisms in the …

The Usability Of Neopterin In Determining Disease Course In Covid-19, Duru Mıstanoglu Ozatag, Pınar Korkmaz, Havva Keskin, Havva Koçak

Saudi Medical Journal

Objectives: To investigate the usability of neopterin in demonstrating the progression of COVID-19. As a result of uncontrolled activation of COVID-19 monocytes and macrophages, IFN gamma increases and the resulting inflammatory response causes organ damage. IFN released from T cells causes an increase in gamma neopterin levels. Therefore, measurement of neopterin levels can be used to indicate immune system activation and disease progression. Methods: The study was carried out prospectively in two different centers. The patients were divided into two groups (mild-moderate and severe) and clinical, laboratory, imaging findings and neopterin levels at hospitalization were compared. Results: 100 patients were …
