Changes in Medication Complexity and Post-Hospitalization Outcomes in Older Adults Hospitalized for Heart Failure.
Drugs Aging
December 2024
Department of Medicine, Weill Cornell Medicine, New York, NY, USA.
Introduction: Medication regimen complexity may be an important risk factor for adverse outcomes in older adults with heart failure. However, increasing complexity is often necessary when prescribing guideline-directed medical therapy at the time of a heart failure hospitalization. We sought to determine whether increased medication regimen complexity following a heart failure hospitalization was associated with worse post-hospitalization outcomes.

: The STOP-IT randomized clinical trial (RCT) pioneered limiting antibiotic agents in intra-abdominal infection (IAI) with adequate surgical source control, but NIH funding ended before an adequate power sample size was enrolled to determine equivalence between STOP-IT study regimens: four days of antibiotic agents (4-days) after source control versus antibiotic agents until resolution of signs and symptoms of IAI plus two days (standard of care [SOC]). The objective of this investigation was to identify possible significant treatment effects 4-days versus SOC, and independent variables defining and predicting outcomes. : De-identified data from 518 STOP-IT subjects were analyzed retrospectively in two groups: 4-days (n = 258) and SOC (n = 260), and separately as one group (n = 518).

Hospital of Chengdu University of Traditional Chinese Medicine, Chengdu 610072, Sichuan Province, China.
Background: Determining the benign or malignant status of indeterminate pulmonary nodules (IPN) with intermediate malignancy risk is a significant clinical challenge. Oral microbiota-lung cancer interactions have qualified oral microbiota as a promising non-invasive predictive biomarker in IPN.
Materials And Methods: Prospectively collected saliva, throat swabs, and tongue coating samples from 1040 IPN patients and 70 healthy controls across three hospitals.
Neural Networks for Conversion of Simulated NMR Spectra from Low-Field to High-Field for Quantitative Metabolomics.
Metabolites
December 2024
Department of Biomedical Engineering, The University of Memphis, Memphis, TN 38152, USA.
The introduction of benchtop NMR instruments has made NMR spectroscopy a more accessible, affordable option for research and industry, but the lower spectral resolution and SNR of a signal acquired on low magnetic field spectrometers may complicate the quantitative analysis of spectra. In this work, we compare the performance of multiple neural network architectures in the task of converting simulated 100 MHz NMR spectra to 400 MHz with the goal of improving the quality of the low-field spectra for analyte quantification. Multi-layered perceptron networks are also used to directly quantify metabolites in simulated 100 and 400 MHz spectra for comparison.

Background/objectives: Both aging and chronic obstructive pulmonary disease (COPD) are strongly associated with changes in the metabolome; however, it is unknown whether there are common aging/COPD metabolomic signatures and if accelerated aging is associated with COPD.
Methods: Plasma from 5704 subjects from the Genetic Epidemiology of COPD study (COPDGene) and 2449 subjects from Subpopulations and intermediate outcome measures in COPD study (SPIROMICS) were profiled using the Metabolon global metabolomics platform (1013 annotated metabolites). Post-bronchodilator spirometry measures of airflow obstruction (forced expiratory volume at one second (FEV)/forced vital capacity (FVC) < 0.
