Shift in the timing of microvascular free tissue transfer failures in head and neck reconstruction.

Objective: Analyze the cause and significance of a shift in the timing of free flap failures in head and neck reconstruction.

Study Design: Retrospective multi-institutional review of prospectively collected databases at tertiary care centers.

Methods: Included consecutive patients undergoing free flap reconstructions of head and neck defects between 2007 and 2017.

Intraoperative Pancreatic Cancer Detection using Tumor-Specific Multimodality Molecular Imaging.

Background: Operative management of pancreatic ductal adenocarcinoma (PDAC) is complicated by several key decisions during the procedure. Identification of metastatic disease at the outset and, when none is found, complete (R0) resection of primary tumor are key to optimizing clinical outcomes. The use of tumor-targeted molecular imaging, based on photoacoustic and fluorescence optical imaging, can provide crucial information to the surgeon.

Body mass index impacts in vitro fertilization stimulation.

The objective of the study was to prospectively determine if body mass index (BMI) is predictive of live birth rates in patients undergoing IVF. The prospective study enrolled 117 infertility patients with the primary outcome measure being IVF success rates. Mean BMI did not differ between patients with successful outcomes and those without successful outcomes.

Surgical competence of obstetrics and gynecology residents performing microsurgical tubal anastamoses.

Objective: To assess tubal patency rates after microsurgical tubal anastamosis in a residency program.

Study Design: Retrospective cohort analysis. Primary outcome measurement was tubal patency rates.

SENSE or k-MAG to accelerate free breathing navigator-guided coronary MR angiography.

Objective: The purpose of this study was to assess the relative merits of reducing the scanning time of navigator-guided (NAV) coronary MR angiography by including, both independently and in combination, two time-saving strategies: k-space weighted motion-adapted gating (k-MAG) and sensitivity encoding (SENSE, factor = 2).

Subjects And Methods: Coronary arteries of 21 healthy subjects were imaged with four NAV MR angiography sequences: conventional NAV sequence, NAV with the addition of SENSE, NAV with the addition of k-MAG, and NAV with a combination of SENSE and k-MAG. All imaging parameters including the magnetization preparation schemes, prescribed spatial resolution, and acquisition duration per R-R interval were identical for all techniques.
