Chronic obstructive pulmonary disease (COPD) may be complicated by pulmonary hypertension (PH). We aimed to understand the impact of PH on in-hospital mortality and quantify the 30-day readmission rate among patients with COPD. For this cross-sectional study, we used the Nationwide Readmissions Database from 2017-2020 to identify adults ≥18 years with COPD. Patients were stratified according to PH diagnosis. Baseline characteristics between groups were compared using the Pearson chi-square test and two-sample t-test. Predictors of in-hospital mortality were determined using multivariate logistic regression analysis adjusted for demographics and confounders. The 30-day readmission rate and prevalence of PH subgroups by baseline …

BACKGROUND: There are few prospective studies of mycophenolate mofetil (MMF) versus cyclophosphamide (CYC) for pediatric lupus nephritis (pLN) and none evaluating rituximab (RTX).

METHODS: The Prospective Pediatric Lupus Nephritis Registry (ProPeL-R) enrolled patients <  21 years within 4 weeks of an initial kidney biopsy diagnostic of pLN. Demographic, clinical, and laboratory data were collected prospectively at enrollment, 3 months, 6 months, and then every 6 months thereafter for up to 5 years of follow-up. For this study, we compared patients receiving initial therapy with corticosteroids (CS) and either MMF (n = 33) vs. CYC (n = 18), and those treated with CS, either MMF or CYC, with RTX (n = 20) vs. without RTX (n = 51).

RESULTS: Histology consisted of 18% class III; 35% class IV; 25% mixed class; and 22% pure class V. Eighty-two percent were female. No significant differences in response or infection rates were identified between those receiving MMF or CYC. There was a significant increase in combined complete (CR) and partial response (PR) at 24 months with RTX use. Overall CR rates at 6 and 24 months were 35% …

Ceftaroline Pharmacokinetics On Ecmo, A Pediatric Case Report., Kathryn Pavia, Ashton Bellamy, Alaina Burns, Allison Scott, Ethan A. Poweleit

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: In-vitro studies suggest that patients on extracorporeal membrane oxygenation (ECMO) may struggle to achieve therapeutic ceftaroline exposure to treat infections due to antibiotic sequestration within the ECMO oxygenator; however, there are no published data regarding ceftaroline concentrations from patients supported by ECMO.

PATIENT PRESENTATION: Here we present an analysis of ceftaroline pharmacokinetics in a 5-y-old patient supported on ECMO due to influenza-associated necrotizing pneumonia.

RESULTS: A total of nine concentrations were analyzed, including three concentrations prior to cannulation and six on ECMO. ECMO cannulation was associated with a relatively small change in the volume of distribution (0.17 L/kg to …

BACKGROUND: Slower chronic kidney disease (CKD) progression allows more time for transplant preparation. Whether differences in CKD progression by race/ethnicity associate with preemptive or living donor transplantation in youth has not been well studied.

METHODS: We examined the association between time spent with low eGFR (between 10-30 mL/min/1.73 m²) and odds of preemptive or living donor transplantation among youth with CKD. eGFR was estimated using the bedside Schwartz (if < 18 years) and CKD-EPI 2021 equations (if ≥ 18 years) and the CKiD U25 equation in sensitivity analysis. Time spent with low eGFR was compared by race/ethnicity.

RESULTS: Among 333 youth with CKD (median age 11 years [IQR 7,14]), median time spent with low eGFR was 28.8 months. 77% were preemptively waitlisted, and 45% received preemptive …

A Case Report Of Myocardial Infarction Complicated With Blood Pressure Fluctuations Caused By Pheochromocytoma, Huiping Li, Wei Yang, Yu Feng, You Zhang, Gan-Xin Yan, Chuanyu Gao

Department of Medicine Faculty Papers

Pheochromocytoma typically presents with sustained or paroxysmal hypertension, but initial manifestation as acute non-ST-segment elevation myocardial infarction (NSTEMI) is rare. Peri-procedural hemodynamic fluctuations are often dramatic, making diagnosis and management challenging. We report a 51-year-old male admitted with chest tightness for 17 days. Elevated troponin and coronary angiography showing multivessel disease with total occlusion of the mid-left anterior descending artery (LAD) led to a preliminary diagnosis of NSTEMI. During percutaneous coronary intervention, blood pressure surged to 240/130 mmHg; intravenous nitroprusside caused an instantaneous drop to 95/55 mmHg, with rapid rebound to >200 mmHg upon withdrawal, showing no clear temporal relationship …

Duncan NRI Faculty and Staff Publications

The human brain has the remarkable ability to comprehend and express similar concepts in multiple languages. To understand how it does so, we examined responses of hippocampal neurons during passive listening, directed speaking, and spontaneous conversation in both English and Spanish in a small group of balanced bilinguals. We found a small number of putative "cross-language neurons," whose responses to equivalent words (e.g., "tierra" and "earth") are correlated. However, neurons' semantic tunings differed substantially by language, suggesting language-specific neural implementations. Instead, the crucial driver of translation was a preserved geometric organization of neural responses between the two languages, one that …

The enzymatic role of ABHD6 in insulin secretion and resistance is well documented. However, its non-enzymatic function, especially its effects on metabolic health, including selective hepatic insulin resistance and metabolic dysfunction-associated steatotic liver disease (MASLD), is poorly understood. To define the role of ABHD6 in liver physiology, we generated liver-specific ABHD6 knockout mice, as well as liver-specific native and enzymatically inactive mutant ABHD6 overexpression mouse models. We demonstrate that non-enzymatic ABHD6 contributes to the regulation of selective hepatic insulin resistance and MASLD progression. Mechanistically, we show that ABHD6 localizes to the nucleus and interacts with Akt/FoxO1 axis to regulate insulin …
