BACKGROUND: Several observational studies have supported the use of conscious sedation (CS) for endovascular thrombectomy in patients with acute ischemic stroke and associated general anesthesia (GA) with poor functional outcomes. Recently, few randomized controlled trials have shown no difference in the functional outcomes between GA and CS. The aim of this paper is to compare the outcomes of GA versus CS in patients with acute ischemic stroke undergoing mechanical thrombectomy in the MOST (Multi-arm Optimization of Stroke Thrombolysis) trial.

METHODS: Patients who underwent mechanical thrombectomy for acute ischemic stroke under GA or CS in the MOST trial were included. The …

Optimization of prophylactic vaccine regimens to elicit strong, long-lasting immunity is an urgent need highlighted by the COVID-19 pandemic. Stronger vaccine immunogenicity is frequently reported in individuals living in high-income countries compared to individuals living in low- and middle-income countries. While numerous host genetic and immune factors may influence vaccine responses, geographic restrictions to vaccine effectiveness may also be influenced by the intestinal microbiota, which modulates host immune systems. However, the potential role of the gut microbiota on responses to HIV-1 vaccines has not yet been explored. We analyzed the bacteriome by targeted 16S sequencing and the virome by virus-like …

Animals must balance behavioral goals with the energetic costs of movement. How such trade-offs are implemented algorithmically during natural behavior, and how they adapt to changing energetic constraints, remains poorly understood. Here we show that larval zebrafish adjust their motor strategies during prey hunting to minimize energy expenditure. Using high-speed video tracking and 3D computational fluid dynamics simulations, we quantified the energy costs (in Joules) of different movement types across three developmental stages. While the structure of discrete movement types ("bouts") remained stable with age, their selection probabilities changed depending on their energetic cost, such that more expensive bouts were …

Despite advances in immunotherapy, the prognosis for patients with glioblastoma (GBM) remains poor. The efficacy of GBM-targeted immunotherapies is limited by the paucity of functional T cells in the tumor microenvironment, a consequence of the local and systemic immunosuppression prevalent in patients with GBM. To overcome these challenges, here we develop a treatment strategy we term "expand and pull," which uses systemic administration of rhIL-7-hyFc, a long-acting recombinant human interleukin-7, to increase peripheral T cell abundance ("expand"), followed by intratumoral oncolytic virus treatment to recruit these cells to the tumor microenvironment ("pull"). We show that rhIL-7-hyFc improves the efficacy of …

Remnant Cholesterol And Atherosclerotic Cardiovascular Disease Risk In Populations With Different Low-Density Lipoprotein Cholesterol Elevations: A Prospective Cohort Study, Hong Zheng, Guanlin Chen, Zhenyu Huo, Yulong Lan, Yuxian Wang, Peng Fu, Weiqiang Wu, Haixiang Zheng, Kuangyi Wu, Zegui Huang, Dan Wu, Shouling Wu, Youren Chen

Research outputs 2022 to 2026

Background: Low-density lipoprotein cholesterol (LDL-C) and remnant cholesterol (RC) are risk factors for atherosclerotic cardiovascular disease (ASCVD). However, the extent to which differences in RC levels affect ASCVD risk in populations with varying degrees of LDL-C elevation remains unclear. This study aimed to investigate whether RC can provide additional risk stratification value across different sexes, ages, and elevated LDL-C statuses. Methods: This study included 12 743 elevated LDL-C participants (LDL-C ≥3.4 mmol/L) and 50 073 age- and sex-matched non-elevated LDL-C controls from the Kailuan Study. Elevated LDL-C participants were categorized by RC levels into <0.5, 0.5 to <1.0, and ≥1.0 mmol/L subgroups. Kaplan-Meier curves and Cox proportional hazards models were used to assess the relationship between RC levels and ASCVD risk across different sexes, ages, and high LDL-C statuses. Results: During a median follow-up of 12.8 years, 1686 elevated LDL-C participants (13.2%) and 5252 non-elevated LDL-C participants (10.5%) developed ASCVD. In the borderline-high LDL-C group (3.4 ≤ LDL-C < 4.1 mmol/L), those with the lowest RC levels showed no significant risk difference compared with controls (hazard ratio [HR], 1.03 [95% CI, 0.93-1.13]), and this pattern remained consistent across different sexes and ages. In contrast, in the high LDL-C group (LDL-C ≥4.1 mmol/L), even when RC was at the lowest level, ASCVD risk remained significantly higher than that of controls (HR, 1.20 [95% CI, 1.02-1.41]). CONCLUSIONS: In the borderline-high LDL-C population, those with the lowest RC levels showed no significant risk difference compared with controls, and this pattern remained consistent across different sexes and age subgroups. In the high LDL-C population, even when RC was at the lowest level, ASCVD risk remained significantly higher than that of controls.

Lymphatic Pumping Failure In The Arm Precedes Dermal Backflow And Breast Cancer-Related Lymphedema, Melissa B Aldrich, Meghan E Mcwain, Simona F Shaitelman, Rian E Kuhns, John C Rasmussen, Wendy A Woodward, Sarah M Desnyder, Wenyaw Chan, Eva M Sevick-Muraca

The Brown Foundation: Institute of Molecular Medicine

Background

Breast cancer patients who undergo regional nodal irradiation therapy (RNI) following neoadjuvant chemotherapy and mastectomy or lumpectomy with axillary lymph node dissection (ALND) frequently encounter breast cancer-related lymphedema (BCRL). Early detection and treatment can significantly improve outcomes. Previously, near-infrared fluorescence lymphatic imaging (NIRF-LI) detection of dermal backflow, or retrograde lymphatic flow into initial lymphatics, was shown to precede clinical BCRL diagnosis by 8–23 months. Herein, we hypothesize that lymphatic pump failure is responsible for dermal backflow and may be a target to prevent onset of BCRL symptoms.

S6k1 Modulates Stat3 Activation To Promote Resistance To Radiotherapy In Lung Cancer, Ali Calderon-Aparicio, Noelle Francois, Tyler Grenda, Shan Xu, Olugbenga Okusanya, Jun He, Nicole L Simone

Department of Radiation Oncology Faculty Papers

Radiotherapy is a mainstay in the management of locally advanced lung cancer; however, intrinsic and acquired radioresistance contribute to poor prognosis. S6K1, a serine/threonine kinase, regulates cell growth, protein synthesis, and survival, and is increased in tumors, which is linked to enhanced survival under therapeutic stress, including radiation. The mechanisms, however, are not fully understood. This study investigates the role of S6K1 in lung cancer radioresistance and the mechanisms involved. Intrinsic radioresistance in lung cancer cells was associated with increased S6K1 activation. Pharmacologic inhibition or genetic deletion of S6K1 enhanced radiosensitivity both in vitro and in vivo, highlighting the therapeutic …

Triple-negative breast cancer (TNBC) exhibits heterogeneous treatment responses, yet molecular subtypes based on predefined biological pathways show limited prognostic value. We introduce tumor-specific total mRNA expression (TmS), a pathway-agnostic deconvolution metric derived from matched RNA/DNA sequencing, as a robust stratification tool. Analyzing 575 TNBC patients across Western and East Asian populations, TmS outperforms established subtypes in predicting chemotherapy outcomes, stratifying patients into high TmS with favorable prognosis and low TmS with poor prognosis. Stromal enrichment with immune exclusion emerges as a universal feature of chemotherapy-resistant low-TmS tumors across all cohorts. Population-specific features distinguish Asian cohorts: high-TmS tumors exhibit cell cycle-driven …

Pancreatic ductal adenocarcinoma (PDAC) remains one of the deadliest malignancies, with a 5-year survival rate of just 13%. While the development and early clinical use of small molecules targeting oncogenic KRAS mutations, key drivers of PDAC, have shown promise, resistance to these targeted therapies remains a significant challenge. We recently identified Syndecan-1 (SDC1), a highly expressed heparan sulfate proteoglycan, as a critical KRAS effector protein that promotes nutrient salvage and tumor growth. Here, we report the development of a human-specific monoclonal antibody (anti-SDC1 mAb) that inhibits PDAC cell proliferation in vitro and suppresses PDAC tumor growth in vivo. Mechanistically, …

Bergmann glia (BG) are a specialized glial population essential for cerebellar development, yet their developmental timeline and molecular identity in the human cerebellum remain poorly understood. Here, we combined detailed histopathological analysis with spatial transcriptomics and single-nucleus RNA sequencing to generate a developmental atlas of human cerebellar BG. Histology revealed that BG emerge around 11 post-conception weeks (PCW), initially serving as a scaffold for Purkinje cells (PCs) migrating into the PC layer of the cerebellar cortex. Following the establishment of a multilayered PC arrangement, BG form a distinct parallel layer separated from the PCs by the lamina dissecans (LD), with …

Metastatic Castrate-Resistant Prostate Cancer To The Penis Resulting In Malignant Priapism And Urethral Obstruction, Courtney Stewart, Joon Yau Leong, William Kevin Kelly, Mihir Shah

Department of Urology Faculty Papers

A 76-year-old male with metastatic castrate-resistant prostate cancer was found to have metastatic disease to the urethra and penis on PSMA PET scan. This resulted in constant pain due to obstruction of blood flow through the corpora cavernosum resulting in priapism and urethral obstruction. The patient underwent a radical penectomy, partial urethrectomy and perineal urethrostomy creation. Final pathology confirmed metastatic prostatic adenocarcinoma. Although rare, prostate cancer can metastasize to the corpora spongiosum or cavernosa. Treatment options are limited, and surgical excision with urinary diversion is likely to provide the most durable outcomes for one's quality of life.

Non-Canonical Role Of Dna Mismatch Repair On Sensory Processing In Mice, Sadia N Rahman, Demetrios Neophytou, Siboney Oviedo-Gray, Bao Q Vuong, Hysell V Oviedo

2020-Current year OA Pubs

DNA repair mechanisms are essential for cellular development and function. In post-mitotic neurons, deficiencies in DNA damage response proteins can lead to severe neurodegenerative and neurodevelopmental disorders. One highly conserved factor involved in DNA repair is MutS Homolog 2 (Msh2), which is responsible for correcting base-base mismatches and insertion/deletion loops during cell proliferation. However, its role in mature neurons remains poorly understood. This study investigates the impact of Msh2 loss on sensory processing in mice. Using electrophysiological and molecular assays, we identifiedsignificant deficits in cortical and thalamic sound processing in Msh2

Department of Medicine Faculty Papers

Background: Navigational bronchoscopy (NB) enables precise sampling of peripheral and central pulmonary nodules using shape-sensing or electromagnetic guidance. A major challenge is anesthesia-induced atelectasis, which alters lung anatomy, reduces registration accuracy, and is known to lower diagnostic accuracy. To counteract this, ventilatory protocols such as the Ventilatory Strategy to Prevent Atelectasis (VESPA) and the Lung Navigation Ventilation Protocol (LNVP) have been recommended. Their adoption and clinical impact, however, remain uncertain. Methods: We conducted a retrospective review of 224 consecutive NB procedures performed under general anesthesia at a single academic medical center (January 2020–August 2024). Demographic, anesthetic, and ventilatory data were …

Radiation therapy (RT) is the standard of care for glioblastoma but is not curative. Triggering the cGAS/stimulator of interferon genes (STING) pathway with potent agonists, such as 8803, exerts activity across high-grade glioma preclinical models. To determine if the combination of 8803 with RT warrants consideration in the up-front treatment setting and to clarify the underlying mechanisms of therapeutic activity, C57BL/6J mice harboring intracerebral CT-2A or QPP8v gliomas were treated with RT, intratumoral 8803, or both. The treatment with the combination resulted in 80% long-term survival in the CT-2A model but not in the radiation-resistant QPP8v model. This therapeutic effect …
