Post-surgical spinal infection occurs in up to 20 % of patients, despite aggressive peri-operative antibiotic treatments. To improve prophylaxis, we have designed and evaluated an ultrasound-activated prophylactic antibiotic release system to combat post-surgical bacterial survival. Polylactic acid (PLA) clips (1 cm³) were 3D-printed with an interior reservoir (0.8 cm³) for carrying drug payload, specifically vancomycin (VAN). Under IACUC approval, clips were surgically implanted into the spines of sheep (n = 9) and swine (n = 2) by removing the spinous process at several levels of the lumbar spine. In the sheep, clips were insonated and the …

The prognostic impact of measurable residual disease (MRD) in acute myeloid leukemia (AML) is unequivocal; however, the optimal time point for achieving undetectable MRD is unclear. We retrospectively studied patients with newly diagnosed (ND) AML who achieved remission with frontline intensive chemotherapy and had MRD assessed by flow cytometry after induction (time point 1 [TP1]) and after cycles 2 or 3 (TP2). Cases were grouped into MRD negative (Neg)/Neg, positive (Pos)/Neg, or Pos/Pos at TP1 and TP2, respectively. Of 1980 patients with ND AML, 277 met the inclusion criteria and were included in this analysis. The median relapse-free survival (RFS) …

Impact Of Prior Car T-Cell Therapy On Mosunetuzumab Efficacy In Patients With Relapsed Or Refractory B-Cell Lymphomas, Elise A Chong, Nancy L Bartlett, Et Al.

2020-Current year OA Pubs

Mosunetuzumab and other CD20/CD3 bispecific antibodies (BsAbs) have efficacy in B-cell lymphomas relapsing after or refractory to CD19-directed chimeric antigen receptor (CAR)-modified T cells (CAR-T). The optimal timing of BsAbs and biomarkers of BsAb response after CAR-T are unknown. We addressed these questions using clinical data and blood samples from patients previously treated with CAR-T and subsequently treated on a phase 1/2 study of mosunetuzumab. Thirty patients had paired samples at baseline and after 1 cycle of mosunetuzumab. The median time from CAR-T to mosunetuzumab was significantly longer for responding than for nonresponding patients (P = .006, unadjusted for multiple …

Faculty, Staff and Student Publications

Non-invasive and high-temporal resolution methods for characterizing blood flow in mouse cranial arteries, such as the ophthalmic artery (OphA), are lacking. We present an application of pulsed Doppler ultrasound to provide real-time, non-invasive measurement of blood flow velocity in the OphA through an identified soft tissue window in the mouse head. We confirmed the identity of the artery and mapped its origin from the internal carotid artery by a combination of microcomputed tomography (microCT) vascular imaging and transient occlusion of the internal carotid artery. Application of our approach demonstrated sex differences in the OphA vasodilative response to agonists. We also …

Memorability Of Novel Words Correlates With Anterior Fusiform Activity During Reading, Oscar Woolnough, Nitin Tandon

Faculty, Staff and Student Publications

Our memory for the words we already know is best predicted by their associated meanings. However, the factors that influence whether we will remember a new word after we see it for the first time are unclear. We record memory performance for 2100 novel pseudowords across 1804 participants during a continuous recognition task. Participants show significant agreement across individuals for which novel words were memorable or forgettable, suggesting an intrinsic memorability for individual pseudowords. Pseudowords that are similar to low-frequency known words, with sparse orthographic neighbourhoods and rarely occurring letter pairs, are more memorable. Further, using intracranial recordings in 36 …

Black Community Member Perceptions And Ethics Recommendations On Epigenomic Research., Courtney D. Berrios, Tammy Basey, Andrea Bradley-Ewing, Stacey Daniels-Young, Daysha Lewis, Keith Feldman, Mary Moffatt, Tomi Pastinen, Elin Grundberg

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Social epigenomics research investigates links between social experiences and epigenetic modifications, which may ultimately impact health. Such research holds promise for precision medicine and addressing health disparities based on social conditions, but also brings unique ethical challenges. The linking of social experiences to biological changes risks pathologizing experiences, potentially leading individuals and communities to be seen as 'damaged.' This stigmatization or stereotyping based on experiences also risks placing disproportionate personal responsibility for health. These risks are likely to be amplified in historically marginalized communities already facing discrimination. It is therefore essential to engage members of historically marginalized communities to …

Routine Evaluation Of Supracondylar Humerus Fracture Percutaneous Pin Sites Does Not Decrease Complications: A Retrospective Comparative Cohort, Alexis Aboulafia, Brendan Grant, Rohini M Vanodia, Lindsay M Crawford, Shiraz A Younas, Alfred A Mansour

Faculty, Staff and Student Publications

Background: Supracondylar humerus (SCH) fractures are the most common type of pediatric elbow fractures that require surgical intervention. Studies suggest limiting the first postoperative visit to the time of pin removal or limiting radiographs at first postoperative follow-up may not increase complication rates, but few comparative studies exist. This study aims to determine if routinely examining surgical pins sites at the first postoperative visits affects the complication rates or outcomes compared to only evaluating pin sites if a clinical indication exists.

Methods: This cohort study retrospectively reviewed patients who were surgically treated for a supracondylar humerus fracture at a Pediatric …

The Effects Of Major Abdominal Surgery On Skeletal Muscle Mitochondrial Respiration In Relation To Systemic Redox Status And Cardiopulmonary Fitness, Jia L. Stevens, Daniel Martin, Helen Mckenna, Magdalena Minnion, Andrew Murray, Martin Feelisch

Peninsula Medical School

More complex surgeries are being performed in increasingly sicker patients, resulting in a greater burden of postoperative morbidity. Delineating the metabolic and bioenergetic changes that occur in response to surgical stress may further our understanding about how humans respond to injury and aid the identification of resilient and frail phenotypes. Skeletal muscle biopsies were taken from patients undergoing hepato-pancreatico-biliary surgery at the beginning and end of the procedure to measure mitochondrial respiration and thiol status. Blood samples were taken at the same timepoints to measure markers of inflammation and systemic redox state. A sub-group of patients underwent cardiopulmonary exercise testing …

Post-Traumatic Growth And Influencing Factors Of Parents With Children With Duchenne Muscular Dystrophy: A Cross-Sectional Survey Study, Li Xu, Meili Liu, Yuewei Chen, Liwen Wu, Siyi Gan, Jianhui Xie, Jos M. Latour

School of Nursing and Midwifery

Background: The aim of the study was to identify the post-traumatic growth status and influencing factors of parents with children with Duchenne muscular dystrophy (DMD). Methods: We adopted a cross-section survey study. Between February and December 2022, 181 parents responded to the survey including a participants’ characteristics section, post-traumatic growth assessment scale, caregiver burden scale, and social support assessment scale. Multiple linear regression analysis was used to investigate influencing factors of post-traumatic growth. Results: The mean score of post-traumatic growth of parents was 56.66 (SD ± 18.67). Post-traumatic growth was positively correlated with social support (r = 0.452, P < 0.01) and negatively correlated with care burden (r = -0.207, P < 0.01). Multiple linear regression showed that the child’s age, course of disease, self-care ability, parent’s working condition, residence, education, number of children, and health status were the main influencing factors for the post-traumatic growth of parents (P < 0.001). Conclusion: The post-traumatic growth of parents with children with DMD was at a moderate level. Healthcare professionals should pay attention to the psychological state of parents with children with this rare disease and promote post-traumatic growth through psychological mindfulness interventions, strengthening family and social support, and providing care knowledge and skills.

Antibiotic (ABX)–induced microbiome dysbiosis is widespread in oncology, adversely affecting outcomes and side effects of various cancer treatments, including immune checkpoint inhibitors and chimeric antigen receptor T-cell (CAR-T) therapies. In this study, we observed that prior exposure to broad-spectrum ABXs with extended anaerobic coverage such as piperacillin-tazobactam and meropenem was associated with worse anti-CD19 CAR-T therapy survival outcomes in patients with large B-cell lymphoma (N = 422) than other ABX classes. In a discovery subset of these patients (n = 67), we found that the use of these ABXs was in turn associated with substantial dysbiosis of gut microbiome function, …

Aif3 Splicing Variant Elicits Mitochondrial Malfunction Via The Concurrent Dysregulation Of Electron Transport Chain And Glutathione-Redox Homeostasis, Mi Zhou, Shuiqiao Liu, Yanan Wang, Bo Zhang, Ming Zhu, Jennifer E Wang, Veena Rajaram, Yisheng Fang, Weibo Luo, Yingfei Wang

Faculty, Staff and Student Publications

Genetic mutations in apoptosis-inducing factor (AIF) have a strong association with mitochondrial disorders; however, little is known about the aberrant splicing variants in affected patients and how these variants contribute to mitochondrial dysfunction and brain development defects. We identified pathologic AIF3/AIF3-like splicing variants in postmortem brain tissues of pediatric individuals with mitochondrial disorders. Mutations in AIFM1 exon-2/3 increase splicing risks. AIF3-splicing disrupts mitochondrial complexes, membrane potential, and respiration, causing brain development defects. Mechanistically, AIF is a mammalian NAD(P)H dehydrogenase and possesses glutathione reductase activity controlling respiratory chain functions and glutathione regeneration. Conversely, AIF3, lacking these activities, disassembles mitochondrial complexes, increases …

Zika Virus Ns1 Drives Tunneling Nanotube Formation For Mitochondrial Transfer And Stealth Transmission In Trophoblasts, Rafael T Michita, Long B Tran, Steven J Bark, Deepak Kumar, Shay A Toner, Joyce Jose, Indira U Mysorekar, Anoop Narayanan

Faculty, Staff and Students Publications

Zika virus (ZIKV) is unique among orthoflaviviruses in its vertical transmission capacity in humans, yet the underlying mechanisms remain incompletely understood. Here, we show that ZIKV induces tunneling nanotubes (TNTs) in placental trophoblasts which facilitate transfer of viral particles, proteins, mitochondria, and RNA to neighboring uninfected cells. TNT formation is driven exclusively via ZIKV non-structural protein 1 (NS1). Specifically, the N-terminal 1-50 amino acids of membrane-bound ZIKV NS1 are necessary for triggering TNT formation in host cells. Trophoblasts infected with TNT-deficient ZIKV

The oral microbiota, second in abundance to the gut, is implicated in chronic systemic diseases, but its specific role in graft-versus-host disease (GVHD) pathogenesis has been unclear. Our study finds that mucositis-induced oral dysbiosis in patients after hematopoietic cell transplantation (HCT) associated with increased chronic GVHD (cGVHD), even in patients receiving posttransplant cyclophosphamide. In murine HCT models, oral dysbiosis caused by bilateral molar ligatures exacerbated cGVHD and increased bacterial load in the oral cavity and gut, with Enterococcaceae significantly increasing in both organs. In this model, the migration of Enterococcaceae to cervical lymph nodes both before and after transplantation activated …

Chromosomal And Gonadal Sex Have Differing Effects On Social Motivation In Mice, Sneha M Chaturvedi, Simona Sarafinovska, Din Selmanovic, Katherine B Mccullough, Raylynn G Swift, Susan E Maloney, Joseph D Dougherty

2020-Current year OA Pubs

BACKGROUND: Sex differences in brain development are thought to lead to sex variation in social behavior. Sex differences are fundamentally driven by both gonadal hormones and sex chromosomes, yet little is known about the independent effects of each on social behavior. Further, mouse models of the genetic liability for the neurodevelopmental disorder MYT1L Syndrome have shown sex-specific deficits in social motivation. In this study, we aimed to determine if gonadal hormones or sex chromosomes primarily mediate the sex differences seen in mouse social behavior, both at baseline and in the context of Myt1l haploinsufficiency.

METHODS: Four-core genotypes (FCG) mice, which …
