Objectives: Guidelines recommend hydrocortisone as an adjunctive treatment in septic shock, but the optimal dosing regimen is unknown. A national shortage of hydrocortisone in 2023 prompted a change in institutional practice for hydrocortisone administration from 50 mg every 6 hours to 100 mg every 12 hours in an effort to reduce waste and conserve vials, creating an opportunity to evaluate the comparative effectiveness of these two regimens. The primary efficacy outcome was time to shock resolution, and secondary outcomes evaluated in this study were mortality, renal replacement therapy (RRT), medication costs, and maximum vasopressor dose attained.

Design: Single-center, retrospective cohort …

Chagas disease, caused by the protozoan Trypanosoma cruzi, is a significant challenge for canine health, with limited diagnostic tools. This study assessed the performance of a novel Tc-24 recombinant antigen ELISA compared to three commercial diagnostic tests on 70 serum samples from kennel dogs in Texas. The Tc-24 ELISA demonstrated high sensitivity (87.5%) and specificity (91.2%) compared to Indirect Fluorescent Antibody (IFA) testing, with significant differences in Tc-24 optical density (OD) between positives and negatives (0.607 vs. 0.089, p < 0.001). When compared to Chagas Stat-Pak (SP), Tc-24 ELISA showed sensitivity and specificity values of 82.1% and 86.7%, respectively (p < 0.001). For Chagas Detect Plus (IB), the assay achieved a sensitivity of 80.0% and specificity of 93.1% (p < 0.001). Spearman correlation analysis revealed significant associations between Tc-24 OD and SP (r = 1.0, p = 0.0167), IB (r = 0.9, p = 0.0833) and IFA (r = 0.6273, p = 0.044). Elevated immunochromatographic values in commercial kits (SP or IB) correlated with Tc-24 OD (1.17 vs. 0.039, p < 0.001), achieving 100% sensitivity and 95.8% specificity based on positive results from commercial kits. These findings suggest that Tc-24 ELISA is a reliable and accurate serological tool for diagnosing T. cruzi infection in dogs, with the potential to enhance diagnostic capabilities in veterinary medicine.

The Role Of Serum Phosphate Control In Supporting Transplant Readiness In Patients On Dialysis, Laura A Williams, Stephen Z Fadem

Faculty, Staff and Students Publications

Chronic kidney disease affects over 36 million Americans, with more than 800,000 progressing to end-stage kidney disease (ESKD). Treatment with kidney transplantation offers superior survival, quality of life, and cost-effectiveness compared with dialysis, yet access remains limited. Hyperphosphatemia is a highly prevalent and modifiable complication of ESKD that contributes to cardiovascular disease, mineral bone disorder, and potential pulmonary dysfunction. Additionally, elevated serum phosphate has been linked to transplant graft failure and adverse post-transplant outcomes. Although normal phosphate levels are not formally required for transplant eligibility, they are frequently considered as part of transplant readiness assessments. Persistent gaps between clinical guideline …

Botulinum neurotoxins (BoNT) are the most potent protein toxins for humans, yet how BoNT-Light Chain/A1 (LC/A1) journeys to cleave intracellular SNAP-25 is understudied. Here we use a cell-based assay to measure cytosolic EGFP-LC/A1 intracellular trafficking and SNAP-25 cleavage in Neuro-2A cells. Intracellular LC/A1 associated on microtubules and co-localized with Rab GTPases involved in fast synaptic vesicles and endosome recycling. Multiple Dominant Negative (DN) Rabs GTPases involved in fast synaptic vesicles or endosome recycling inhibited LC/A1 trafficking to the intracellular plasma membrane and SNAP-25 cleavage. A cytosolic LC/A1 variant that bound the plasma membrane from the cytosol was insensitive to DNRab …

Over 95% of ependymomas that arise in the cortex are driven by a gene fusion involving the zinc finger translocation-associated (ZFTA) protein. Here, using super-resolution and lattice light-sheet microscopy, we demonstrate that the most frequent fusion variant, ZFTA-RELA (ZR), forms dynamic nuclear condensates that are required for oncogene expression and tumorigenesis. Mutagenesis studies of ZR reveal a key intrinsically disordered region (IDR) in RELA that governs condensate formation. Condensate-modulating IDR mutations introduced into ZR impaired its genomic occupancy at oncogenic loci and inhibited the recruitment of transcriptional effector proteins, such as MED1, BRD4 and RNA polymerase II. Using nuclear magnetic …
