Gantenerumab Reduces Amyloid-Β Plaques In Patients With Prodromal To Moderate Alzheimer's Disease: A Pet Substudy Interim Analysis, Gregory Klein, Paul Delmar, Nicola Voyle, Sunita Rehal, Carsten Hofmann, Danielle Abi-Saab, Mirjana Andjelkovic, Smiljana Ristic, Guoqiao Wang, Randall Bateman, Geoffrey A Kerchner, Monika Baudler, Paulo Fontoura, Rachelle Doody

Open Access Publications

BACKGROUND: We previously investigated low doses (105 or 225 mg) of gantenerumab, a fully human monoclonal antibody that binds and removes aggregated amyloid-β by Fc receptor-mediated phagocytosis, in the SCarlet RoAD (SR) and Marguerite RoAD (MR) phase 3 trials. Several lines of evidence suggested that higher doses may be necessary to achieve clinical efficacy. We therefore designed a positron emission tomography (PET) substudy to evaluate the effect of gantenerumab uptitrated to 1200 mg every 4 weeks on amyloid-β plaques as measured using florbetapir PET in patients with prodromal to moderate Alzheimer's disease (AD).

METHODS: A subset of patients enrolled in …

Optical interrogation of voltage in deep brain locations with cellular resolution would be immensely useful for understanding how neuronal circuits process information. Here, we report ASAP3, a genetically encoded voltage indicator with 51% fluorescence modulation by physiological voltages, submillisecond activation kinetics, and full responsivity under two-photon excitation. We also introduce an ultrafast local volume excitation (ULoVE) method for kilohertz-rate two-photon sampling in vivo with increased stability and sensitivity. Combining a soma-targeted ASAP3 variant and ULoVE, we show single-trial tracking of spikes and subthreshold events for minutes in deep locations, with subcellular resolution and with repeated sampling over days. In the …

Snord94 Expression Level Alters Methylation At C62 In Snrna U6., Allison Ogren, Nataliya Kibiryeva, Jennifer A. Marshall, James O'Brien, Douglas C. Bittel

Manuscripts, Articles, Book Chapters and Other Papers

Understanding the regulation of development can help elucidate the pathogenesis behind many developmental defects found in humans and other vertebrates. Evidence has shown that alternative splicing of messenger RNA (mRNA) plays a role in developmental regulation, but our knowledge of the underlying mechanisms that regulate alternative splicing are incomplete. Notably, a subset of small noncoding RNAs known as scaRNAs (small cajal body associated RNAs) contribute to spliceosome maturation and function through guiding covalent modification of spliceosomal RNAs with either methylation or pseudouridylation on specific nucleotides, but the developmental significance of these modifications is not well understood. Our focus is on …

Articles, Abstracts, and Reports

BACKGROUND: Enthesitis is one of the psoriatic arthritis (PsA) domains. Patients with enthesitis are associated with worse outcomes than those without enthesitis. The effect of secukinumab on the resolution of enthesitis in patients with PsA was explored using pooled data from the FUTURE 2 and 3 studies.

METHOD: Assessments of enthesitis through week 104 used the Leeds Enthesitis Index. These post hoc analyses included resolution of enthesitis count (EC = 0), median time to first resolution of enthesitis (Kaplan-Meϊer estimate), and shift analysis (as observed) of baseline EC (1, 2, or 3-6) to full resolution (FR), stable (similar or reduction …

Combination Of Pembrolizumab And Bcg Treatment After Endoscopic Ablation Of High-Risk Superficial Upper Urinary Tract Urothelial Carcinoma In Patients Not Candidates For Radical Nephroureterectomy: Protocol For Phase-Ii Study, Marcus L. Jamil, Mustafa Deebajah, Akshay Sood, Shaheen Alanee

Urology Articles

INTRODUCTION: The treatment standard for high-risk upper urinary tract urothelial carcinoma (UUTUC) is radical nephroureterectomy. However, some patients may be unfit or unwilling, and in such patients the available alternatives are suboptimal. Therapies targeting the programmed death (PD) pathway have shown promise in urothelial carcinom (UC). We designed the current study to determine the safety and efficacy of administering MK-3475 (a monoclonal antibody targeting interaction between PD-1 and its ligand) in combination with bacillus Calmette-Guerin (BCG) in high-risk non-muscle invasive UUTUC patients.

METHODS: This represents a single-centre phase-II efficacy study of MK-3475 therapy in combination with BCG for subjects, 18 …

Chronic critical illness is a global clinical issue affecting millions of sepsis survivors annually. Survivors report chronic skeletal muscle weakness and development of new functional limitations that persist for years. To delineate mechanisms of sepsis-induced chronic weakness, we first surpassed a critical barrier by establishing a murine model of sepsis with ICU-like interventions that allows for the study of survivors. We show that sepsis survivors have profound weakness for at least 1 month, even after recovery of muscle mass. Abnormal mitochondrial ultrastructure, impaired respiration and electron transport chain activities, and persistent protein oxidative damage were evident in the muscle of …

Perseverance, Faith And Stoicism: A Qualitative Study Of Medical Student Perspectives On Managing Fatigue, Taryn S Taylor, Alexandra L Raynard, Lorelei Lingard

Obstetrics & Gynaecology Publications

CONTEXT: Fatigue risk management (FRM) strategies offer a potential solution to the widespread problem of fatigued trainees in the clinical workplace. These strategies assume a shared perception that fatigue is hazardous. Despite the growing body of evidence suggesting that fatigue leads to burnout and medical errors, previous research suggests that residents perceive fatigue as a personal, surmountable burden rather than an occupational hazard. Before we can implement FRM, we need a better understanding of when and how such problematic notions of fatigue are adopted by medical trainees. Thus, we sought to explore how third-year medical students understand and manage the …

African American Female Law Enforcement Officers' Lived Experiences And Mentoring: A Thematic Narrative, Harold Wilson

Doctoral Dissertations

Black female officers are an underrepresented sub-group of the law-enforcement profession. The bulk of research on women’s policing has focused on the growth of women in law enforcement, barriers, sexual harassment, gender differences, why women are deterred from law enforcement, physical limitations, and instruments used during the recruitment process, and the stress endured after entry into the profession. When looking at Black female officers’ lived experience and perceptions around mentoring; research is lacking. Eight Black female officers from the San Francisco Bay Area participated in this study. Findings revealed that all of the women have faced a recurring sense of …

All Works

© 2019, The Author(s). The value people attribute to rewards is influenced both by the time and the effort required to obtain them. Impairments in these computations are described in patients with schizophrenia and appear associated with negative symptom severity. This study investigated whether deficits in temporal and effort cost computations can be observed in individuals with subclinical psychotic symptoms (PS) to determine if this dysfunction is already present in a potentially pre-psychotic period. Sixty participants, divided into three groups based on the severity of PS (high, medium and low), performed two temporal discounting tasks with food and money and …

A Consumer Neuroscience Study Of Conscious And Subconscious Destination Preference, Thomas Zoëga Ramsøy, Noela Michael, Ian Michael

All Works

© 2019, The Author(s). In studying consumer behaviors, the inclusion of neuroscience tools and methods is improving our understanding of preference formation and choice. But such responses are mostly related to the consumption of goods and services that meet an immediate need. Tourism represents a consumer behavior that is related to a more complex decision-making process, involving a stronger relationship with a future self, and choices typically being of a higher level of involvement and of a transformational type. The aim of this study was to test whether direct emotional and cognitive responses to travel destination would be indicative of …

© 2019, The Author(s). Incense burning is common worldwide and produces environmental toxicants that may influence health; however, biologic effects have been little studied. In 303 Emirati adults, we tested the hypothesis that incense use is linked to compositional changes in the oral microbiota that can be potentially significant for health. The oral microbiota was assessed by amplification of the bacterial 16S rRNA gene from mouthwash samples. Frequency of incense use was ascertained through a questionnaire and examined in relation to overall oral microbiota composition (PERMANOVA analysis), and to specific taxon abundances, by negative binomial generalized linear models. We found …

The Community Structure Of Functional Brain Networks Exhibits Scale-Specific Patterns Of Inter- And Intra-Subject Variability, Richard F Betzel, Maxwell A Bertolero, Evan M Gordon, Caterina Gratton, Nico U F Dosenbach, Danielle S Bassett

2010-2019 OA Pubs

The network organization of the human brain varies across individuals, changes with development and aging, and differs in disease. Discovering the major dimensions along which this variability is displayed remains a central goal of both neuroscience and clinical medicine. Such efforts can be usefully framed within the context of the brain's modular network organization, which can be assessed quantitatively using computational techniques and extended for the purposes of multi-scale analysis, dimensionality reduction, and biomarker generation. Although the concept of modularity and its utility in describing brain network organization is clear, principled methods for comparing multi-scale communities across individuals and time …

Cognitive Change In Cognitive-Behavioural Therapy, Leanne Quigley, David J A Dozois, R Michael Bagby, Daniela S S Lobo, Lakshmi Ravindran, Lena C Quilty

Psychology Publications

BACKGROUND: Although cognitive-behavioural therapy (CBT) is a well-established treatment for adult depression, its efficacy and efficiency may be enhanced by better understanding its mechanism(s) of action. According to the theoretical model of CBT, symptom improvement occurs via reductions in maladaptive cognition. However, previous research has not established clear evidence for this cognitive mediation model.

METHODS: The present study investigated the cognitive mediation model of CBT in the context of a randomized controlled trial of CBT v. antidepressant medication (ADM) for adult depression. Participants with major depressive disorder were randomized to receive 16 weeks of CBT (n = 54) or ADM …

A Rare Site Of Spread Of A Common Cancer, Sameen Khalid, Graziella Paniz, Aamer Abbass, Edgar Fischer, Gulshan Parasher, Denis Mccarthy

Pathology Research and Scholarship

Breast cancer is the most commonly diagnosed malignancy affecting women worldwide with estimated 252,710 new cases of invasive breast cancer in women in the USA in 2017. It is the second most prevalent cause of cancer-related death after lung cancer in females with an expected annual mortality rate of 16% [1]. Promotion of public awareness, screening programs, early diagnosis, intensive local treat- ment, and changes in chemotherapy regimens with endo- crine and targeted therapy account for a notable decrease in mortality. Nevertheless, these measures do not seem to have impacted the prognosis in patients with distant metastasis. Breast cancer has …

Post-Acquisition Processing Confounds In Brain Volumetric Quantification Of White Matter Hyperintensities, Ahmed A. Bahrani, Omar M. Al-Janabi, Erin L. Abner, Shoshana H. Bardach, Richard J. Kryscio, Donna M. Wilcock, Charles D. Smith, Gregory A. Jicha

Neurology Faculty Publications

BACKGROUND: Disparate research sites using identical or near-identical magnetic resonance imaging (MRI) acquisition techniques often produce results that demonstrate significant variability regarding volumetric quantification of white matter hyperintensities (WMH) in the aging population. The sources of such variability have not previously been fully explored.

NEW METHOD: 3D FLAIR sequences from a group of randomly selected aged subjects were analyzed to identify sources-of-variability in post-acquisition processing that can be problematic when comparing WMH volumetric data across disparate sites. The methods developed focused on standardizing post-acquisition protocol processing methods to develop a protocol with less than 0.5% inter-rater variance.

RESULTS: A series …
