Background: Gastrointestinal endoscopic procedures (GIEP's) are an essential part of patient care both diagnostically and therapeutically. Post-GIEP infections may be higher than previously reported and may not have been accurately captured in the past. The aim of this study was to determine the incidence and associated factors of bacteremia associated with GIEP's.
Methods: This is retrospective study of GIEPs performed over a five-year period (2018-2022) at an academic medical center. Electronic health records (EHR) identified GIEPs and positive blood cultures within 30 days of procedure. Statistical analysis was performed using non-parametric testing to compare variables due to the small number of positive blood cultures.
Results: EHR identified 18,986 GIEP's and 52 true and unique bacteremia out of 17,093 blood cultures during the five-year study period. The highest rate of positive blood culture of 2.84% (18/ 634) was associated with ERCP and the lowest 0.08% (7/ 9029) was associated with colonoscopy.
Discussion: Our study showed a reflection of the endemic rate of bacteremia post GIEP's. Our study cannot differentiate endogenous infection versus contaminated (exogenous) endoscopes. ERCP procedures are disproportionately associated with higher incidence of bacteremia.
Conclusions: Clinical surveillance in non-outbreak settings is essential for estimating GIEP related infections. It should be combined with endoscopic reprocessing audits for appropriate prevention of GIEP associated infections.

Nitroglycerin is a potent vasodilator in clinical use since the late 1800s. It functions as a prodrug that is bioactivated by formation of an enzyme-based thionitrate, E-Cys-NO. This intermediate reportedly decomposes to release NO and NO but their relative yields remain controversial.

B-type natriuretic peptide (BNP) levels accurately reflect the degree of cardiac overload in heart failure. Considering cardiac morphology and intracardiac pressure, including the left ventricular end-systolic volume index (LVESVI) and left ventricular end-diastolic volume index (LVEDVI), is essential for cardiac overload assessment. These indexes influence plasma BNP levels, and high heart rate is likely associated with cardiac morphology.

The triglyceride to high density lipoprotein cholesterol (TG/HDL-C) ratio has been consistently linked with the risk of coronary heart disease (CHD). Nevertheless, there is a paucity of studies focusing on acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI) or experiencing bleeding events. The study encompassed 17,643 ACS participants who underwent PCI.

Aging is associated with increased tumor metastasis and poor prognosis. However, how an aging immune system contributes to the process is unclear. Here, single-cell RNA sequencing reveals that in male mice, aging shifts the lung immune microenvironment towards a premetastatic niche, characterized by an increased proportion of IL-17-expressing γδT (γδ17) and neutrophils.

Hodgkin Reed-Sternberg (HRS) cells of classic Hodgkin lymphoma (cHL), like many solid tumors, elicit ineffective immune responses. However, patients with cHL are highly responsive to PD-1 blockade, which largely depends on HRS cell-specific retention of MHC class II and implicates CD4 T cells and additional MHC class I-independent immune effectors. Here, we utilize single-cell RNA sequencing and spatial analysis to define shared circulating and microenvironmental features of the immune response to PD-1 blockade in cHL.
