Establishing reference curves for vital tissue perfusion using quantitative near-infrared fluorescence imaging with indocyanine green.

Purpose: Assessment of tissue perfusion using near-infrared fluorescence (NIR) with indocyanine green (ICG) is gaining popularity, however reliable and objective interpretation remains a challenge. Therefore, this study aimed to establish reference curves for vital tissue perfusion across target tissues using this imaging modality.

Methods: Data from five prospective study cohorts conducted in three Dutch academic medical centres between December 2018 and June 2023 was included.

Cardiac inotropy and cardiac calcium sensitization of PanLN800(-Forte), a cationic heptamethine indocyanine fluorescent contrast agent for intraoperative pan lymph node imaging.

Introduction: Accurate staging of malignancies often requires comprehensive evaluation of lymph nodes. However, finding these lymph nodes during oncological surgery is a daunting and time-consuming task, which increases the risk of missed lymph nodes and complications. Near-infrared (NIR) fluorescence imaging with the experimental fluorescent contrast agent PanLN800(-Forte) could provide real-time identification of lymph nodes and may solve this longstanding problem.

Indocyanine green near-infrared fluorescence bowel perfusion assessment to prevent anastomotic leakage in minimally invasive colorectal surgery (AVOID): a multicentre, randomised, controlled, phase 3 trial.

Background: Anastomotic leakage is a severe postoperative complication in colorectal surgery and compromised bowel perfusion is considered a major contributing factor. Conventional methods to assess bowel perfusion have a low predictive value for anastomotic leakage. We therefore aimed to evaluate the efficacy of real-time assessment with near-infrared (NIR) fluorescence imaging with indocyanine green (ICG) in the prevention of anastomotic leakage.

Evaluation of treatment with human chorionic gonadotropin at transfer of in vitro-produced beef embryos on reproductive outcomes in lactating multiparous Jersey cows after a synchronized ovulation.

Our objective was to evaluate the effect of treatment with human chorionic gonadotropin (hCG) at the time of transfer of in vitro-produced (IVP) beef embryos on pregnancy outcomes in lactating multiparous Jersey cows. Grade 1, stage 7 (expanded blastocyst), IVP beef embryos were produced from black Angus-based dams using 3 proven high-fertility Angus sires and were frozen for direct transfer. In a preliminary experiment, lactating multiparous Jersey cows were randomized to a 2 × 2 factorial arrangement of treatments to test the main effect of recipient synchronization protocol (Double-Ovsynch; DO; n = 169 vs.

Prevalence of asymptomatic TFCC tears on MRI: A systematic review.

Background: Recent studies show a high prevalence of triangular fibrocartilage complex (TFCC) tears in asymptomatic wrists. While a TFCC tear may be identified when evaluating ulnar sided wrist pain, this could be incidental and not the true cause of pain. The purpose of this review was to (1) examine the frequency of which TFCC tears are diagnosed on MRI in asymptomatic versus symptomatic wrists and (2) determine whether rates of asymptomatic TFCC tears are higher in two important subgroups commonly at risk for this pathology: elderly patients and high-impact athletes.
