Faculty, Staff and Student Publications

Background and objectives: We report the recording of sudden unexpected death in epilepsy (SUDEP) in a 68-year-old man with recent onset cryptogenic epilepsy, captured by video-EEG monitoring, at home in the company of his wife while sitting in a chair. This was only the third seizure of his life, the first 2 occurring 19 days previously. This rare event is a novel case of SUDEP recorded with ambulatory video EEG at home. The video is included by permission.

Methods: Electroclinical seizure and cardiorespiratory analysis was ascertained using a combination of video, EEG (Natus, standard 10-20 electrode), ECG, and sound. Respiratory …

Prenatal Cocaine Exposure And Its Influence On Pediatric Epigenetic Clocks And Epigenetic Scores In Humans, Thiago Wendt Viola, Christina Danzer, Victor Mardini, Claudia Szobot, João Henrique Chrusciel, Laura Stertz, Joy M Schmitz, Consuelo Walss-Bass, Gabriel R Fries, Rodrigo Grassi-Oliveira

Faculty, Staff and Student Publications

The investigation of the effects of prenatal cocaine exposure (PCE) on offspring has been inconsistent, with few studies investigating biological outcomes in humans. We profiled genome-wide DNA methylation (DNAm) of umbilical cord blood (UCB) from newborns with (n = 35) and without (n = 47) PCE. We used DNAm data to (1) assess pediatric epigenetic clocks at birth and (2) to estimate epigenetic scores (ES) for lifetime disorders. We generated gestational epigenetic age estimates (DNAmGA) based on Knight and Bohlin epigenetic clocks. We also investigated the association between DNAmGA and UCB serum brain-derived neurotrophic factor (BDNF) levels. Considering the large-scale …

Nutritional Requirements And Effect Of Culture Conditions On The Performance Of The African Catfish (Clarias Gariepinus): A Review, Sandra Langi, Sahya Maulu, Oliver J. Hasimuna, Veronica Kaleinasho Kapula, Martin Tjipute

School of Biological and Marine Sciences

Aquaculture is crucial for global food and nutrition security due to the inability of wild harvests to meet increasing demand. Africa’s contribution to aquaculture is generally low, despite its potential for economic development, food security, and reduced unemployment. The study focuses on the African catfish (Clarias gariepinus) a freshwater fish species that is widely farmed for food in Africa and other parts of the world. Proper nutrition is essential for the growth and development of the fish, and understanding their nutritional requirements is critical for producing healthy and high-quality fish. This review article provides an overview of the knowledge on …

Rehabilitation For Enduring Change: Toward Evidence-Based Corrections, Michael Rocque

All Faculty Scholarship

Since Robert Martinson’s famous declaration that there was little evidence on the effectiveness of rehabilitation, correctional research on what works to reduce recidivism has proliferated. There is a vast body of literature indicating that programs and interventions, when applied appropriately in prison or in the community, can be effective. Intervention approaches with relatively strong evidence include (1) educational/vocational, (2) cognitive-behavioral therapy, (3) substance use/abuse, and some evidence for (4) sex offender programs. However, there is a large amount of variability in the results of evaluations, and the sources of that variability need to be interrogated. While there is increasingly good …

Acculturation And Intimate Partner Violence Among Kenyans In The United States, Max J. Stein, Peter Ndiang’Ui, Eunice Menja

Journal of Social, Behavioral, and Health Sciences

Intimate partner violence (IPV) is abuse by a partner or spouse. This study focused on IPV among Kenyan immigrants to the United States. Several studies reported connections between IPV and cultural tensions experienced during the acculturation process. Scholars disagree whether acculturation buffers against IPV by exposing immigrants to adaptive social norms or heightens risk factors among those facing challenges acclimating to new settings. Whereas this association has been researched among Latinx and Asian communities in the United States, it is understudied among African and especially Kenyan diasporas. This descriptive study explored how acculturation and IPV among U.S. Kenyans were experienced …

Adverse Outcomes And An Immunosuppressed Endotype In Septic Patients With Reduced Ifn-Γ Elispot, Evan L. Barrios, Drew E. Del Toro, Alexandra Dram, Sandra Meszaros, Sydney Miles, Andrew H. Walton, Anne M. Drewry, Isaiah R. Turnbull, Richard S Hotchkiss, Et Al.

2020-Current year OA Pubs

BACKGROUNDSepsis remains a major clinical challenge for which successful treatment requires greater precision in identifying patients at increased risk of adverse outcomes requiring different therapeutic approaches. Predicting clinical outcomes and immunological endotyping of septic patients generally relies on using blood protein or mRNA biomarkers, or static cell phenotyping. Here, we sought to determine whether functional immune responsiveness would yield improved precision.METHODSAn ex vivo whole-blood enzyme-linked immunosorbent spot (ELISpot) assay for cellular production of interferon γ (IFN-γ) was evaluated in 107 septic and 68 nonseptic patients from 5 academic health centers using blood samples collected on days 1, 4, and 7 …

An Orally Available Compound Suppresses Glucagon Hypersecretion And Normalizes Hyperglycemia In Type 1 Diabetes, Farzad Asadi, Subhadra C. Gunawardana, Roland E. Dolle, David W. Piston

2020-Current year OA Pubs

Suppression of glucagon hypersecretion can normalize hyperglycemia during type 1 diabetes (T1D). Activating erythropoietin-producing human hepatocellular receptor type-A4 (EphA4) on α cells reduced glucagon hypersecretion from dispersed α cells and T1D islets from both human donor and mouse models. We synthesized a high-affinity small molecule agonist for the EphA4 receptor, WCDD301, which showed robust plasma and liver microsome metabolic stability in both mouse and human preparations. In islets and dispersed islet cells from nondiabetic and T1D human donors, WCDD301 reduced glucagon secretion comparable to the natural EphA4 ligand, Ephrin-A5. In diabetic NOD and streptozotocin-treated mice, once-daily oral administration of WCDD301 …

Neuronal Deletion Of The Circadian Clock Gene Bmal1 Induces Cell-Autonomous Dopaminergic Neurodegeneration, Michael K. Kanan, Patrick W. Sheehan, Jessica N. Haines, Pedro G. Gomez, Adya Dhuler, Collin J. Nadarajah, Zachary M. Wargel, Brittany M. Freeberg, Hemanth R. Nelvagal, Mariko Izumo, Joseph S. Takahashi, Jonathan D. Cooper, Albert A. Davis, Erik S. Musiek

2020-Current year OA Pubs

Circadian rhythm dysfunction is a hallmark of Parkinson disease (PD), and diminished expression of the core clock gene Bmal1 has been described in patients with PD. BMAL1 is required for core circadian clock function but also serves nonrhythmic functions. Germline Bmal1 deletion can cause brain oxidative stress and synapse loss in mice, and it can exacerbate dopaminergic neurodegeneration in response to the toxin MPTP. Here we examined the effect of cell type-specific Bmal1 deletion on dopaminergic neuron viability in vivo. We observed that global, postnatal deletion of Bmal1 caused spontaneous loss of tyrosine hydroxylase+ (TH+) dopaminergic neurons in the substantia …

Neural Mechanisms Of Face Familiarity And Learning In The Human Amygdala And Hippocampus, Runnan Cao, Jinge Wang, Peter Brunner, Jon T Willie, Xin Li, Ueli Rutishauser, Nicholas J Brandmeir, Shuo Wang

2020-Current year OA Pubs

Recognizing familiar faces and learning new faces play an important role in social cognition. However, the underlying neural computational mechanisms remain unclear. Here, we record from single neurons in the human amygdala and hippocampus and find a greater neuronal representational distance between pairs of familiar faces than unfamiliar faces, suggesting that neural representations for familiar faces are more distinct. Representational distance increases with exposures to the same identity, suggesting that neural face representations are sharpened with learning and familiarization. Furthermore, representational distance is positively correlated with visual dissimilarity between faces, and exposure to visually similar faces increases representational distance, thus …

Targeting Efferocytosis In Inflammaging, Ivan K H Poon, Kodi S Ravichandran

2020-Current year OA Pubs

Rapid removal of apoptotic cells by phagocytes, a process known as efferocytosis, is key for the maintenance of tissue homeostasis, the resolution of inflammation, and tissue repair. However, impaired efferocytosis can result in the accumulation of apoptotic cells, subsequently triggering sterile inflammation through the release of endogenous factors such as DNA and nuclear proteins from membrane permeabilized dying cells. Here, we review the molecular basis of the three key phases of efferocytosis, that is, the detection, uptake, and degradation of apoptotic materials by phagocytes. We also discuss how defects in efferocytosis due to the alteration of phagocytes and dying cells …

Faculty, Staff and Student Publications

BACKGROUND: Frailty is associated with worse outcomes and higher healthcare costs. The long waiting time for surgery is a potential 'teachable' moment. We examined the feasibility and safety of a pilot prehabilitation programme on high-risk frail patients undergoing major elective surgery.

METHODS: A single-centre, retrospective pilot study (Dec 2020-Nov 2021) on a one-stop prehabilitation programme (structured exercise training, nutritional counselling/therapy, and psychological support) in collaboration with geriatricians and allied health professionals. At least 4 weeks before surgery, patients at high risk of frailty or malnutrition, or undergoing major hepatectomy, esophagectomy, pancreaticoduodenectomy, or radical cystectomy, were referred for prehabilitation (2-3 sessions/week). …

BACKGROUND AND OBJECTIVES: Evidence of the so-called "obesity paradox," which refers to the protective effect and survival benefit of obesity in patients with spontaneous intracerebral hemorrhage (ICH), remains controversial. This study aims to determine the association between body mass index (BMI) and functional outcomes in patients with ICH and whether it is modified by race/ethnicity.

METHODS: Included individuals were derived from the Ethnic/Racial Variations of Intracerebral Hemorrhage study, which prospectively recruited 1,000 non-Hispanic White, 1,000 non-Hispanic Black, and 1,000 Hispanic patients with spontaneous ICH. Only patients with available BMI were included. The primary outcome was 90-day mortality. Secondary outcomes were …

Addressing Comorbidities In People With Parkinson's Disease: Considerations From An Expert Panel, Camille Carroll, Carl E. Clarke, Donald Grosset, Arshad Rather, Biju Mohamed, Miriam Parry, Prashanth Reddy, Robin Fackrell, Kallol Ray Chaudhuri

Peninsula Medical School

In the UK, guidance exists to aid clinicians and patients deciding when treatment for Parkinson's disease (PD) should be initiated and which therapies to consider. National Institute for Health and Care Excellence (NICE) guidance recommends that before starting PD treatment clinicians should discuss the following: the patient's individual clinical circumstances; lifestyle; preferences; needs and goals; as well as the potential benefits and harms of the different drug classes. Individualization of medicines and management in PD significantly improves patients' outcomes and quality of life. This article aims to provide simple and practical guidance to help clinicians address common, but often overlooked, …

Teacher Professionalism, Expertise And The Jurisdictional Struggle, Jim Hordern

School of Law, Humanities and Social Sciences

In this paper, the relationship between teacher professionalism, expertise and educational knowledge is examined via the sociology of the professions, studies of professional knowledge, and the philosophy of expertise. Drawing on the work of Abbott the jurisdictional context of teaching is foregrounded, with a focus on (i) how educational problems are defined; (ii) professional knowledge-in-use (or diagnosis, inference and “treatment” in teaching); and (iii) the potential of systematically organised abstract knowledge base for teaching. It is suggested that teaching is a profession particularly vulnerable to external jurisdictional challenge, with little opportunity for protection against forms of what Abbott terms “advisory” …

71st St. Props. Llc V. New York State Div. Of Hous. & Community Renewal

All Decisions

Landlord sought to compel DHCR to issue a decision on their eviction application for demolition under Rent Stabilization Code §2524.5(a)(2). The court denied the petition, finding DHCR's decision on eviction for demolition discretionary and entitled to deference in its resource allocation and decision-making process (CPLR §7803(1); Matter of 81 Warren St. Realty Corp. v New York State Div. of Hous. & Community Renewal, 2008 NY Slip Op 31030[U]).

Department of Medicine Faculty Papers

INTRODUCTION: In recent years, there has been a national push to incorporate high-fidelity quality improvement and patient safety (QIPS) education into physician training programs. In fact, integration of robust patient safety education became an Accreditation Council for Graduate Medical Education (ACGME) Common Program Requirement for residency programs in 2017. We developed a curriculum to not only fulfill the ACGME's requirement but also provide PGY 1 internal medicine residents with the skills needed to become active participants in ongoing patient safety work throughout their training and careers.

METHODS: Our patient safety curriculum was woven into residents' existing protected educational time and …

Human Whole-Exome Genotype Data For Alzheimer's Disease, Yuk Yee Leung, Carlos Cruchaga, Et Al.

2020-Current year OA Pubs

The heterogeneity of the whole-exome sequencing (WES) data generation methods present a challenge to a joint analysis. Here we present a bioinformatics strategy for joint-calling 20,504 WES samples collected across nine studies and sequenced using ten capture kits in fourteen sequencing centers in the Alzheimer's Disease Sequencing Project. The joint-genotype called variant-called format (VCF) file contains only positions within the union of capture kits. The VCF was then processed specifically to account for the batch effects arising from the use of different capture kits from different studies. We identified 8.2 million autosomal variants. 96.82% of the variants are high-quality, and …

Ischemia/reperfusion injury-mediated (IRI-mediated) primary graft dysfunction (PGD) adversely affects both short- and long-term outcomes after lung transplantation, a procedure that remains the only treatment option for patients suffering from end-stage respiratory failure. While B cells are known to regulate adaptive immune responses, their role in lung IRI is not well understood. Here, we demonstrated by intravital imaging that B cells are rapidly recruited to injured lungs, where they extravasate into the parenchyma. Using hilar clamping and transplant models, we observed that lung-infiltrating B cells produce the monocyte chemokine CCL7 in a TLR4-TRIF-dependent fashion, a critical step contributing to classical monocyte …

Synergistic Protection Of Retinal Ganglion Cells (Rgcs) By Sarm1 Inactivation With Cntf In A Rodent Model Of Nonarteritic Anterior Ischemic Optic Neuropathy, Yan Guo, Zara Mehrabian, Jeffrey Milbrandt, Aaron Diantonio, Steven L Bernstein

2020-Current year OA Pubs

We evaluated whether inhibiting sterile alpha and (Toll/interleukin receptor (TIR)) motif-containing 1 (SARM1) activity protects retinal ganglion cells (RGCs) following ischemic axonopathy (rodent nonarteritic anterior ischemic optic neuropathy: rNAION) by itself and combined with ciliary neurotrophic factor (CNTF). Genetically modified SARM1(-) rats were rNAION-induced in one eye and compared against equivalently induced wild-type animals of the same background. Optic nerve (ON) diameters were quantified using optical coherence tomography (SD-OCT). RGCs were quantified 30 d post-induction using retinal stereology for Brn3a(+) nuclei. ON sections were analyzed by TEM and immunohistochemistry. SARM1(-)(-) and WT animals were then bilaterally sequentially rNAION-induced. One eye …

Cpsa Mediates Infection Of Recruited Lung Myeloid Cells By Mycobacterium Tuberculosis, Steven J Grigsby, G V R Krishna Prasad, Joshua B Wallach, Ekansh Mittal, Fong-Fu Hsu, Dirk Schnappinger, Jennifer A Philips

2020-Current year OA Pubs

Mycobacterium tuberculosis (Mtb) possesses an arsenal of virulence factors to evade host immunity. Previously, we showed that the Mtb protein CpsA, which protects Mtb against the host NADPH oxidase, is required in mice during the first 3 weeks of infection but is thereafter dispensable for full virulence. Using flow cytometry, we find that ΔcpsA Mtb is retained in alveolar macrophages, impaired in recruiting and disseminating into monocyte-derived cells, and more likely to be localized in airway cells than wild-type Mtb. The lungs of ΔcpsA-infected mice also have markedly fewer antigen-specific T cells, indicating a delay in adaptive immunity. Thus, we …

Integrative Genomic Analyses Reveal Putative Cell Type-Specific Targets Of The Drosophila Ets Transcription Factor Pointed, Komal Kumar Bollepogu Raja, Kelvin Yeung, Yoon-Kyung Shim, Graeme Mardon

Faculty, Staff and Students Publications

The Ets domain transcription factors direct diverse biological processes throughout all metazoans and are implicated in development as well as in tumor initiation, progression and metastasis. The Drosophila Ets transcription factor Pointed (Pnt) is the downstream effector of the Epidermal growth factor receptor (Egfr) pathway and is required for cell cycle progression, specification, and differentiation of most cell types in the larval eye disc. Despite its critical role in development, very few targets of Pnt have been reported previously. Here, we employed an integrated approach by combining genome-wide single cell and bulk data to identify putative cell type-specific Pnt targets. …

BACKGROUND: It is unknown whether dietary intake of polyunsaturated fatty acids (PUFA) modifies the cardiovascular disease (CVD) risk associated with a family history of CVD. We assessed interactions between biomarkers of low PUFA intake and a family history in relation to long-term CVD risk in a large consortium.

METHODS: Blood and tissue PUFA data from 40 885 CVD-free adults were assessed. PUFA levels ≤25th percentile were considered to reflect low intake of linoleic, alpha-linolenic, and eicosapentaenoic/docosahexaenoic acids (EPA/DHA). Family history was defined as having ≥1 first-degree relative who experienced a CVD event. Relative risks with 95% CI of CVD were …

Climate change is increasing the frequency and severity of short-term (~1 y) drought events-the most common duration of drought-globally. Yet the impact of this intensification of drought on ecosystem functioning remains poorly resolved. This is due in part to the widely disparate approaches ecologists have employed to study drought, variation in the severity and duration of drought studied, and differences among ecosystems in vegetation, edaphic and climatic attributes that can mediate drought impacts. To overcome these problems and better identify the factors that modulate drought responses, we used a coordinated distributed experiment to quantify the impact of short-term drought on …

Impact Of Type Of K Fertilizer On Dcad Of Fen Grassland In Northeast Germany, A. Behrendt, J. Pickert, F. Eulenstein, B. Kroschewski

IGC Proceedings (1977-2023)

A lower DCAD is required in the diet fed during the prepartum period, but increasing the DCAD of diets fed during lactation increased milk yield and dry matter intake (Overton 2020). We conducted 3 cutting date/type of fertilizer trials, harvested with 5, 4 and 3 cuts per year over 3 years. Compared to the chloride based K fertilizer, the application of a sulphate based K fertilizer did not change dry matter yield and fodder quality (NEL-, XP-content) but led to significant higher DCAD in the grass in cut 1 - 3 of all trials over 3 years. The increase of …

Breeding Small Grains As A Forage, Silage And Cover Crop For The Southern Coastal Plain (Usa) In A Changing Climatic Environment, A. Blount, Marcelo O. Wallau, S. A. Harrison, Cheryl L. Mackowiak, A. Babar, José C. B. Dubeux Jr.

IGC Proceedings (1977-2023)

Forage breeding of small grains in the southern Coastal Plains region of the U.S. mimic many other countries experiencing climate changes and breeding strategies should be similar for improving small grains grown for forage, silage or as cover crops. Significant focus on improvements in stress-adaptation has encouraged members of the SunGrains cooperative to cross, evaluate and develop experimental lines with inherent adaptation to climatic conditions including heat stress, drought tolerance, short-day and long-day forage production periods, and flooded conditions for events with storm-related, short-term durations. Many new cultivars, grown throughout the southeastern U.S. have resulted from breeding selection under abiotic …
