Intestinal Oxygen Utilisation And Cellular Adaptation During Intestinal Ischaemia-Reperfusion Injury, Eleni Laou, Athanasios Chalkias Jan 2025

Intestinal Oxygen Utilisation And Cellular Adaptation During Intestinal Ischaemia-Reperfusion Injury, Eleni Laou, Athanasios Chalkias

Faculty, Staff and Student Publications

The gastrointestinal tract can be deranged by ailments including sepsis, trauma and haemorrhage. Ischaemic injury provokes a common constellation of microscopic and macroscopic changes that, together with the paradoxical exacerbation of cellular dysfunction and death following restoration of blood flow, are collectively known as ischaemia-reperfusion injury (IRI). Although much of the gastrointestinal tract is normally hypoxemic, intestinal IRI results when there is inadequate oxygen availability due to poor supply (pathological hypoxia) or abnormal tissue oxygen use and metabolism (dysoxia). Intestinal oxygen uptake usually remains constant over a wide range of blood flows and pressures, with cellular function being substantively compromised …

Integrating multi-omics data may help researchers understand the genetic underpinnings of complex traits and diseases. However, the best ways to integrate multi-omics data and use them to address pressing scientific questions remain a challenge. One important and topical problem is how to assess the aggregate effect of multiple genomic data types (e.g. genotypes and gene expression levels) on a phenotype, particularly while accommodating routine issues, such as having related subjects' data in analyses. In this paper, we extend an existing composite kernel machine regression model to integrate two multi-omics data types, while accommodating for general correlation structures amongst outcomes.

The Infected Diabetic Foot: Risk Factors For Re-Infection After Treatment For Diabetic Foot Osteomyelitis, Lawrence A Lavery, Mario C Reyes, Bijan Najafi, Tyler L Coye, Matthew Sideman, Michael C Siah, Arthur N Tarricone

Center on Aging Staff Publications

Our objective was to evaluate risk factors for re-infection in patients after treatment for diabetic foot osteomyelitis (OM). We used pooled patient level data from two RTCs that evaluated patients with diabetic foot infections. We evaluated 171 patients with OM. OM was confirmed with bone culture or histopathology. Data from the 12-month follow-up were used to determine clinical outcomes. Re-infection occurred in 47 (27.5%) patients. Risk factors for re-infection were Toe Brachial Index < 0.40 (25.7% vs. 9.8%, p = 0.02), skin perfusion pressure < 40 mmHg (6.3% vs. 5.9%, p = 0.04), wound healing (55.3% vs. 75.0%, p = 0.01), time to heal (156.0, 69.5-365 vs. 91.5, 38.8-365, p = 0.001), and history of MI (14.9% vs. 3.2%, p = 0.005). During 12-month follow-up, patients with re-infections were 198.8 times more likely to require a foot related hospitalisation (81.8% vs. 0.0%, p = 0.001), 10.4 times more likely have an all-cause hospitalisation (70.2% vs. 18.5%, p = 0.001) and 9.4 times more likely to need an amputation (36.2% vs. 5.6%, p = 0.001). Patients with re-infection had a significantly longer median length of hospitalisation (20.0, 13.5-34.5 vs. 14.0, 10.0-22.0, p = 0.003) and median length of antibiotic duration (55.0, 35.0-87.0 vs. 46.0, 22.8-68.0, p = 0.03). Patients with re-infection are less likely to heal and have more foot-related hospitalizations and amputations.

Center on Aging Staff Publications

Cell-cell communication (CCC) plays a critical role in the physiological regulation of organisms and has been implicated in numerous diseases. Previously, we introduced FlyPhoneDB, a tool designed to explore CCC in Drosophila single-cell RNA-sequencing datasets. The core algorithm of FlyPhoneDB infers tissue-specific signaling events between cell types by calculating cell-cell interaction scores based on curated ligand-receptor (L-R) expression across major signaling pathways. However, the utility of FlyPhoneDB was limited by the relatively small number of available L-R pairs.

Here, we present FlyPhoneDB2, a major upgrade featuring a significantly expanded knowledgebase that includes a greater number of L-R pairs, incorporating annotations …
