Developing a clinical prediction model to modify empirical antibiotics for non-typhoidal Salmonella bloodstream infection in children under-five in the Democratic Republic of Congo.

Background: Non-typhoidal Salmonella (NTS) frequently cause bloodstream infection in children under-five in sub-Saharan Africa, particularly in malaria-endemic areas. Due to increasing drug resistance, NTS are often not covered by standard-of-care empirical antibiotics for severe febrile illness. We developed a clinical prediction model to orient the choice of empirical antibiotics (standard-of-care versus alternative antibiotics) for children admitted to hospital in settings with high proportions of drug-resistant NTS.

Inflammatory disease microbiomes share a functional pathogenicity predicted by C-reactive protein.

We examine disease-specific and cross-disease functions of the human gut microbiome by colonizing germ-free mice, at risk for inflammatory arthritis, colitis, or neuroinflammation, with over 100 human fecal microbiomes from subjects with rheumatoid arthritis, ankylosing spondylitis, multiple sclerosis, ulcerative colitis, Crohn's disease, or colorectal cancer. We find common inflammatory phenotypes driven by microbiomes from individuals with intestinal inflammation or inflammatory arthritis, as well as distinct functions specific to microbiomes from multiple sclerosis patients. Inflammatory disease in mice colonized with human microbiomes correlated with systemic inflammation, measured by C-reactive protein, in the human donors.

Lobectomy verses Sublobar Resection in The Society of Thoracic Surgeons Database: Importance of Patient Factors and Lymph Node Evaluation.

Background: Prospective randomized trials have demonstrated noninferior survival between sublobar resection and lobectomy in healthy non-small cell lung cancer (NSCLC) patients with tumors ≤2cm. However, some patient attributes are not well represented in randomized trials and uncertainty remains in the widespread applicability of randomized trial nodal dissection protocols.

Methods: Patients with ≤2cm, node-negative NSCLC (cT1N0) in the Society of Thoracic Surgeons prospective database were linked to Medicare survival data using a probabilistic matching algorithm.

The Society of Thoracic Surgeons National Intermacs Database Risk Model for Durable Left Ventricular Assist Device Implantation.

Background: Statistical risk models for durable left ventricular assist device (LVAD) implantation inform candidate selection, quality improvement, and evaluation of provider performance. We developed a 90-day mortality risk model utilizing The Society of Thoracic Surgeons National Intermacs Database (STS Intermacs).

Methods: STS Intermacs was queried for primary durable LVAD implants from 1/ 2019 - 9/2023.
