Few Patients Receive Testing After Abnormal Urine Protein Results
Too few patients with abnormal urine protein dipstick test results receive the recommended follow-up with albumin to creatinine ratio (ACR) testing to assess albuminuria, a risk factor for chronic kidney disease, according to new research published in the Annals of Internal Medicine.
Protocol for a randomised, double-blinded, controlled trial of youth with childhood-onset obesity treated with semaglutide 2.4 mg/week: the RESETTLE trial
Introduction
Childhood-onset obesity poses significant health risks, including early-onset type 2 diabetes, cardiovascular disease, and reduced quality of life. Hospital-based non-pharmacological obesity care can reduce childhood obesity, but 25% of children do not respond. Therefore, this study investigates the effect of the glucagon-like peptide-1 receptor agonist, semaglutide, as an add-on to hospital-based obesity care in youth who still have obesity following hospital-based obesity care as children. Furthermore, biomedical and psychosocial factors linked to treatment response will be investigated, alongside an exercise-based strategy to prevent weight regain and maintain a healthy body composition after semaglutide treatment.
Methods and analysis
This is an investigator-initiated, randomised, placebo-controlled, double-blind trial. We will enrol expectedly 180–270 young adults aged 18–28 years based on their previous response to a paediatric obesity management programme and their current body mass index (BMI). Participants are categorised into four groups: low treatment response (BMI SD score (SDS) reduction 0.25; BMI ≥30 kg/m2); high treatment response (BMI SDS reduction >0.50; BMI
Abstract 4136905: EF-24, a curcumin analog, reverses interleukin-18-induced miR-30b or miR-342-dependent TRAF3IP2 expression, RECK suppression, and the proinflammatory phenotype of human aortic smooth muscle cells
Circulation, Volume 150, Issue Suppl_1, Page A4136905-A4136905, November 12, 2024. Curcumin, a polyphenolic compound derived from the widely used spiceCurcuma longa,has shown anti-atherosclerotic effects in cultured vascular cells and animal models. We previously reported that the induction of the proinflammatory molecule TRAF3IP2 (TRAF3 Interacting protein 2) or inhibition of the matrix metalloproteinase (MMP) regulator RECK (Reversion Inducing Cysteine Rich Protein with Kazal Motifs) contributes to agonist-induced proinflammatory, pro-oxidant, pro-mitogenic and pro-migratory effects in vascular smooth muscle cells. Here we hypothesized that, EF-24 ((3E,5E)-3,5-bis[2-fluorophenyl (methylene]-4piperidinone), a curcumin analog with better bioavailability and potency, reverses interleukin (IL)-18-induced TRAF3IP2 induction, RECK suppression and the proinflammatory phenotype of primary human aortic smooth muscle cells (ASMC). Exposure to recombinant human IL-18 (10 ng/ml) induced TRAF3IP2 mRNA and protein expression, but markedly suppressed RECK in a time-dependent manner. Further investigations revealed that IL-18 induced miR-30b, but suppressed miR-342, in a p38 MAPK and JNK-dependent manner. While miR-30b inhibitor blunted IL-18-induced TRAF3IP2 expression, miR-30b inhibitor and miR-342 mimic each restored RECK expression. Further, IL-18 induced ASMC migration (Boyden chamber assay) and proliferation (CyQUANT Cell Proliferation assay), and these effects were reversed by TRAF3IP2 knockdown or RECK overexpression. Our results also show that IL-18 induced MMP2 and MMP9 expression and activity, and targeting their expression inhibited IL-18-induced ASMC migration. TRAF3IP2 knockdown or RECK overexpression also reversed IL-18-induced ASMC proinflammatory phenotype switching as evidenced by the enhanced expression of the SMC markers ACTA2 and MYH11, and reduced expression of the proinflammatory markers Galectin 3, Olr1, VCAM, CCL2, IL-6, IL-8, and TNF-α. Importantly, preincubation with EF-24 markedly suppressed IL-18-induced SMC proliferation, MMP expression, migration and the proinflammatory phenotype switching. Together, these results suggest that the curcumin analog EF-24 has therapeutic potential in vascular inflammatory and proliferative diseases, including atherosclerosis, by differentially regulating TRAF3IP2 and RECK in vascular SMC.
Abstract 4139117: Epidemiology of Patients Undergoing a Rapid Response within the First 24 Hours of Admission at an Urban Academic Center
Circulation, Volume 150, Issue Suppl_1, Page A4139117-A4139117, November 12, 2024. Introduction:A Rapid Response Team (RRT) is an inpatient team that aims to resuscitate deteriorating patients in non-critical care settings and reduce inpatient morbidity and mortality. It is not well understood which patients are likely to deteriorate and need a rapid response (RR) within the first 24 hours of admission.Research Question:We sought to identify the most common characteristics for patients who had a RR within 24 hours of admission.Methods:We performed a descriptive analysis evaluating 176 patients who had a RR called within 24 hours of admission to North Shore University Hospital from February 2022 to August 2023. Demographic and clinical variables were assessed, including medical history, admitting diagnosis, and indication for RR.Results:The median age of the population was 73 years; 92 (52.3%) were male, and 91 (51.7%) were white. The most common comorbidities were hypertension (119, 67.6%), coronary artery disease (51, 28.9%), and heart failure (34, 19.3%). Amongst these patients, acute hypoxic respiratory failure (11.6%) was the most common admission diagnosis followed by sepsis (9.7%) (Table 1). The most common reason for the RR was acute mental status change (26.1%) followed by hypotension (25.0%). Average time spent in the ED prior to admission was 6 hours 41 mins. Intensive care unit (ICU) consultation prior to the RRT occurred in 36 patients (20.5%) and 52 patients (29.5%) were transferred to an ICU while 124 (70.5%) remained on the medicine floors. Regarding hospital utilization, 98 (55.7%) patients were admitted within the last year and 47 (26.7%) patients were hospitalized within the last month. 14 (7.9%) patients had an ICU admission in the past year. 38 (21.5%) patients died during the admission post RR.Conclusion:In our cohort of RRs within 24 hours of admission, we observed a high prevalence of cardiac comorbidities and recent hospitalizations, a low prevalence of ICU consults prior to RR, and discordance between admitting diagnoses and reasons for RR. Further studies involving a larger cohort are needed to develop a prediction model for determining patients most at risk of deteriorating after admission and requiring RRs.
Abstract 4136654: Urine Output Response to a Furosemide Infusion is Associated with Acute Kidney Injury in Infants Following Cardiac Surgery
Circulation, Volume 150, Issue Suppl_1, Page A4136654-A4136654, November 12, 2024. Background:Acute kidney injury (AKI) following cardiac surgery in infants is common and associated with longer mechanical ventilation times and length of stay. Prior studies have shown that a lack of responsiveness to bolus dose furosemide has been associated with increased incidence of AKI. However, these studies have excluded patients on continuous furosemide infusions who are often younger, more hemodynamically unstable, and at higher risk for AKI.Hypothesis:Decreased urine output after initiation of a furosemide infusion predicts development of AKI.Methods:A retrospective cohort study of infants (
Abstract 4141280: Machine Learning Predicts 24-Hour Change in Decongestion Biomarkers in Hospitalized Heart Failure Patients
Circulation, Volume 150, Issue Suppl_1, Page A4141280-A4141280, November 12, 2024. Background:Despite recent advances, patients with heart failure (HF) often experience repeat hospitalizations and worsening clinical trajectories from inadequate decongestion. Evidence-based approaches for optimizing interventions in the acute hospital setting for patients with decompensated HF are needed. We evaluated whether machine learning (ML) models can accurately predict next-day levels for decongestion surrogates in hospitalized HF patients.Hypothesis:ML can accurately predict body weight, hematocrit, creatinine, and potassium values in the next 24 hours in hospitalized HF patients.Methods:We utilized national Veterans Affairs (VA) databases to study all patients admitted with HF from January 2014 to July 2022. Records including at least one value for at least one biomarker of interest (body weight, hematocrit, creatinine, and potassium) were included. Patients were randomly split into training (80%), validation (10%), and test (10%) datasets. We trained a recurrent neural network to predict each biomarker’s value on admission day n+1 using data until day n, simulating a scenario where a clinician monitors response to treatment (e.g., diuresis) over a 24-hour cycle. The model that performed best on the validation set was evaluated on the test set. The R2, mean absolute error (MAE), and feature importance were determined.Results:We identified 589,114 admissions involving 124,163 unique patients. The mean (SD) age on admission was 72 (10) years; 98% were male, 69% were white, and 25% were Black. The performance (R2, MAE) for each biomarker model was as follows: body weight (0.94, 6.15 lb.), creatinine (0.92, 0.21 mg/dL), hematocrit (0.86, 1.7%), and potassium (0.53, 0.27 mmol/L). The top predictive features across all models were intravenous or oral diuretic use, patient age, and diastolic blood pressure. The predicted 24-hour change in each biomarker based on total daily diuretic dose for five representative patients is demonstrated in the Figure.Conclusions:ML can accurately predict the 24-hour body weight, hematocrit, creatinine, and potassium values in hospitalized HF patients, suggesting the potential for AI to guide acute in-hospital management.
Abstract 4143839: Irregular Sleep Duration is Associated with Altered 24-Hour Heart Rate Profile in Patients Enrolled in Cardiac Rehabilitation
Circulation, Volume 150, Issue Suppl_1, Page A4143839-A4143839, November 12, 2024. Introduction:Sleep duration is now recognized as an important determinant of cardiovascular (CV) health. Recently, the CV implications of day-to-day variability in sleep duration have become apparent, with irregular sleep duration associated with increased risk of CV disease, including hypertension. However, the relationship between sleep duration variability and ambulatory blood pressure (BP) patterns in the general population or in patients with CV disease is unknown.Research Questions:We sought to investigate whether irregular sleep duration is associated with aberrant ambulatory BP or heart rate (HR) profiles in patients undergoing cardiac rehabilitation (CR).Methods:We recruited a sample of 42 patients with coronary artery disease enrolled in CR at Mayo Clinic Rochester. Participants underwent 24-hour ambulatory BP monitoring and sleep assessment including one week of wrist actigraphy and sleep diary prior to entering CR. Twenty-four hour, awake, and asleep averages were calculated for systolic BP, diastolic BP, and HR. Nocturnal dipping and morning surge were also computed for BP and HR. Sleep regularity was quantified by SD of actigraphy-derived sleep duration and irregular sleep duration was defined as SD >1 hour. Chi-square tests and Mann-Whitney U tests were used to compare groups.Results:Thirty-six participants (22% females, median age [25th,75thIQR] 66.5 [61,75.8] years, body mass index 31.7 [26.9,35.1] kg/m2) had valid actigraphy and ambulatory BP recordings. We found sleep duration SD >1 hour in 36% of them. Demographics and average sleep duration were similar between those with irregular and regular sleep duration (all Ps >0.11). Twenty-four-hour, awake and asleep HR values were comparable between groups (all Ps >0.26). Participants with irregular sleep duration exhibited lower nocturnal HR dipping (9.2 [3.1,11.6] % vs 12.9 [8.9,18.2] %, P=0.019) than their counterparts with regular sleep. Morning HR surge was also attenuated in patients with irregular sleep duration (3 [-1,9] bpm vs 10 [7,14] bpm, P=0.006). Ambulatory SBP and DBP measures did not differ significantly between groups (all Ps >0.17).Conclusions:High day-to-day variability in sleep duration is linked to blunted nocturnal dipping and morning surge in HR in patients with coronary artery disease enrolled in CR. Because altered ambulatory HR profile predicts unfavorable CV outcomes, evaluation of sleep patterns in the CR setting may yield important prognostic information.
