Examining The Most Important Risk Factors For Predicting Youth Persistent And Distressing Psychotic-Like Experiences, Nicole R Karcher, Aristeidis Sotiras, Tara A Niendam, Elaine F Walker, Joshua J Jackson, Deanna M Barch

2020-Current year OA Pubs

BACKGROUND: Persistence and distress distinguish more clinically significant psychotic-like experiences (PLEs) from those that are less likely to be associated with impairment and/or need for care. Identifying risk factors that identify clinically relevant PLEs early in development is important for improving our understanding of the etiopathogenesis of these experiences. Machine learning analyses were used to examine the most important baseline factors distinguishing persistent distressing PLEs.

METHODS: Using Adolescent Brain Cognitive Development (ABCD) Study data on PLEs from 3 time points (ages 9-13 years), we created the following groups: individuals with persistent distressing PLEs (n = 305), individuals with transient distressing …

Tissue-Specific Features Of Innate Lymphoid Cells In Antiviral Defense, Sytse J Piersma

2020-Current year OA Pubs

Innate lymphocytes (ILCs) rapidly respond to and protect against invading pathogens and cancer. ILCs include natural killer (NK) cells, ILC1s, ILC2s, ILC3s, and lymphoid tissue inducer (LTi) cells and include type I, type II, and type III immune cells. While NK cells have been well recognized for their role in antiviral immunity, other ILC subtypes are emerging as players in antiviral defense. Each ILC subset has specialized functions that uniquely impact the antiviral immunity and health of the host depending on the tissue microenvironment. This review focuses on the specialized functions of each ILC subtype and their roles in antiviral …

Trauma-informed medical education (TIME) applies trauma-informed care (TIC) principles to help students manage trauma. We aimed to qualitatively describe the extent to which students perceived the six TIME domains as they navigated critical incidents during their EM clerkship.

METHODS: We employed a constructivist, modified grounded theory approach to explore medical students' experiences. We used the critical incident technique to elicit narratives to better understand the six TIME domains as they naturally appear in the clerkship. Participants were asked to …

Emergency Department Slit Lamp Interdisciplinary Training Via Longitudinal Assessment In Medical Practice, Samara Hamou, Shayan Ghiaee, Christine Chung, Maureen Lloyd, Kelly Khem, Xiao Zhang

Department of Emergency Medicine Faculty Papers

INTRODUCTION: Eye emergencies make up nearly 3% of US emergency department (ED) visits. While emergency physicians (EP) should diagnose and treat these ophthalmologic emergencies, many trainees report limited ocular exposure and insufficient training throughout their residency to confidently conduct a thorough slit-lamp exam.

METHODS: We created an interdisciplinary, simulation-based mastery learning (SBML) curriculum to teach emergency attending physicians how to operate the slit lamp with multimodal learning methodology at a tertiary academic center. The EPs first demonstrate their initial slit-lamp competency with a 20-item checklist, and they then review the necessary curricular content to pass their independent readiness test before …

Faculty, Staff and Students Publications

Drug development for tuberculosis is hindered by the methodological limitations in the definitions of patient outcomes, particularly the slow organism growth and difficulty in obtaining suitable and representative samples throughout the treatment. We developed target product profiles for biomarker assays suitable for early-phase and late-phase clinical drug trials by consulting subject-matter experts on the desirable performance and operational characteristics of such assays for monitoring of tuberculosis treatment in drug trials. Minimal and optimal criteria were defined for scope, intended use, pricing, performance, and operational characteristics of the biomarkers. Early-stage trial assays should accurately quantify the number of viable bacilli, whereas …

A Novel Deep Learning Model Based On Transformer And Cross Modality Attention For Classification Of Sleep Stages, Sahar Hassanzadeh Mostafaei, Jafar Tanha, Amir Sharafkhaneh

Faculty, Staff and Students Publications

The classification of sleep stages is crucial for gaining insights into an individual's sleep patterns and identifying potential health issues. Employing several important physiological channels in different views, each providing a distinct perspective on sleep patterns, can have a great impact on the efficiency of the classification models. In the context of neural networks and deep learning models, transformers are very effective, especially when dealing with time series data, and have shown remarkable compatibility with sequential data analysis as physiological channels. On the other hand, cross-modality attention by integrating information from multiple views of the data enables to capture relationships …

Women’S Health And Kidney Protective Medications, Mythri Shankar, Sehrish Ali, Silvi Shah

Faculty, Staff and Students Publications

Purpose of review: We discuss the sex-based differences in the pharmacokinetics and pharmacodynamics of kidney protective medications and their implications on women's health.

Recent findings: A critical examination of adverse drug reactions highlights the underrepresentation of women in clinical trials for kidney and cardiovascular protective drugs, such as SGLT2 inhibitors, ACE inhibitors, and endothelin receptor antagonists. This underscores the need for sex-specific analyses in clinical studies to accurately assess medication efficacy and safety.

Summary: The research demonstrates that women are more likely to experience adverse events and less likely to benefit from certain treatments, emphasizing the urgent need for healthcare …

Faculty, Staff and Students Publications

Secretogranin III (Scg3) is a diabetic retinopathy (DR)-restricted angiogenic factor identified in preclinical studies as a target for DR therapy. Previously, our group generated and characterized ML49.3, an anti-Scg3 monoclonal antibody (mAb) which we then converted into an EBP2 humanized antibody Fab fragment (hFab) with potential for clinical application. We also generated anti-Scg3 mT4 mAb and related EBP3 hFab. In this study, to identify the preferred hFab for DR therapy, we compared all four antibodies for binding, neutralizing and therapeutic activities in vitro and in vivo. Octet binding kinetics analyses revealed that ML49.3 mAb, EBP2 hFab, mT4 mAb and EBP3 …

Background aims: The success of chimeric antigen receptor (CAR) T-cell therapy in treating B-cell malignancies has led to the evaluation of CAR T-cells targeting a variety of other malignancies. Although the efficacy of CAR T-cells is enhanced when administered post-lymphodepleting chemotherapy, this can trigger bone marrow suppression and sustained cytopenia after CD19.CAR T-cell therapy. Additionally, systemic inflammation associated with CAR T-cell activity may contribute to myelosuppression. Cytopenias, such as neutropenia and thrombocytopenia, elevate the risk of severe infections and bleeding, respectively. However, data on the incidence of prolonged cytopenias after immune effector therapy in the solid tumor context remain limited. …

Manifested U-Waves Prior To Seizure Attacks In A Patient Who Had Remote Subarachnoid Hemorrhage: A Case Report, Nao Kaneko, Masao Watanabe, Shusuke Mori, Isik Turker, Ken Okamoto, Takao Urabe, Tomohiko Ai

2020-Current year OA Pubs

Sudden unexpected death in epilepsy (SUDEP) refers to unpredictable demise of a person following a seizure. Electroencephalograms can directly measure electrical activity in the brain; however, it cannot predict when seizures will occur. The use of electrocardiograms (ECGs) to monitor changes in brain electrical activity has gained attention, recently. In this case report, we retrospectively reviewed ECGs taken before and after seizure activity in a 75-year-old male who had a remote subarachnoid hemorrhage. Interestingly, U-waves appeared prior to his seizures and disappeared afterward, which suggests ECGs can be used to predict epilepsy in a certain population.

Targeting Nuclear Receptor Coactivator Src-1 Prevents Colorectal Cancer Immune Escape By Reducing Transcription And Protein Stability Of Pd-L1, Yilin Hong, Qiang Chen, Zinan Wang, Yong Zhang, Bei Li, Hanshi Guo, Chuanzhong Huang, Xu Kong, Pingli Mo, Nengming Xiao, Jianming Xu, Yunbin Ye, Chundong Yu

Programmed death-ligand 1 (PD-L1) is overexpressed in multiple cancers and critical for their immune escape. It has previously shown that the nuclear coactivator SRC-1 promoted colorectal cancer (CRC) progression by enhancing CRC cell viability, yet its role in CRC immune escape is unclear. Here, we demonstrate that SRC-1 is positively correlated with PD-L1 in human CRC specimens. SRC-1 deficiency significantly inhibits PD-L1 expression in CRC cells and retards murine CRC growth in subcutaneous grafts by enhancing CRC immune escape via increasing tumor infiltration of CD8

Tuberculosis Prevention: Current Strategies And Future Directions, Anca Vasiliu, Leonardo Martinez, Rishi K Gupta, Yohhei Hamada, Tara Ness, Alexander Kay, Maryline Bonnet, Martina Sester, Stefan H E Kaufmann, Christoph Lange, Anna M Mandalakas

Faculty, Staff and Students Publications

BACKGROUND: An estimated one fourth of the world's population is infected with Mycobacterium tuberculosis, and 5-10% of those infected develop tuberculosis in their lifetime. Preventing tuberculosis is one of the most underutilized but essential components of curtailing the tuberculosis epidemic. Moreover, current evidence illustrates that tuberculosis manifestations occur along a dynamic spectrum from infection to disease rather than a binary state as historically conceptualized. Elucidating determinants of transition between these states is crucial to decreasing the tuberculosis burden and reaching the END-TB Strategy goals as defined by the WHO. Vaccination, detection of infection, and provision of preventive treatment are key …
