Intraluminal washout in rectal and sigmoid colon cancer surgeries with double-stapling technique anastomosis: A single-institution prospective study.

Aim: This study aimed to determine the necessity of intraluminal washout through cytological assessment to prevent implantation of exfoliated cancer cells (ECCs) in patients with rectal and sigmoid cancers.

Methods: We studied 140 patients with either sigmoid or rectal cancer who underwent anastomosis surgery using a double-stapling technique. An intraluminal washout sample was collected before and after irrigation with 1000, 1500, or 2000 mL of physiological saline or distilled water.

Identifying the appropriate measurement environment for laser speckle flowmetry of cerebral blood flow in rats.

Laser speckle flowmetry (LSF) is a noninvasive tool for cerebral blood flow (CBF) measurement via a cranial bone window. LSF is influenced by various factors including the extent of removal of bone and dura mater and tissue wetness in the bone window. In this study, we aimed to characterize the effect of these conditions on LSF signals and identify optimal measurement conditions for CBF LSF measurements in rats.

Long-Term Impact of Gender Differences After Transcatheter Aortic Valve Implantation.

Background: The short-term and midterm impact of gender differences on transcatheter aortic valve implantation (TAVI) has been studied. However, the impact on long-term clinical outcomes remains unclear. The objective of the study was to investigate the impact of gender differences after TAVI on long-term clinical outcomes and structural valve deterioration (SVD).
