Pterostilbene-induced tumor cytotoxicity: a lysosomal membrane permeabilization-dependent mechanism.

2012

The phenolic phytoalexin resveratrol is well known for its health-promoting and anticancer properties. Its potential benefits are, however, limited due to its low bioavailability. Pterostilbene, a natural dimethoxylated analog of resveratrol, presents higher anticancer activity than resveratrol. The mechanisms by which this polyphenol acts against cancer cells are, however, unclear. Here, we show that pterostilbene effectively inhibits cancer cell growth and stimulates apoptosis and autophagosome accumulation in cancer cells of various origins. However, these mechanisms are not determinant in cell demise. Pterostilbene promotes cancer cell death via a mechanism involving lysosomal membrane …

Effects of acute CPAP application on baroreflex control of heart rate during sleep in severe obstructive sleep apnea.

2006

Baroreflex control of heart rate during sleep (baroreflex sensitivity; BRS) has been shown to be depressed in obstructive sleep apnoea (OSA), and improved after treatment with continuous positive airway pressure (CPAP). Whether CPAP also acutely affects BRS during sleep in uncomplicated severe OSA is still debatable. Blood pressure was monitored during nocturnal polysomnography in 18 patients at baseline and during first-time CPAP application. Spontaneous BRS was analysed by the sequence method, and estimated as the mean sequence slope. CPAP did not acutely affect mean blood pressure or heart rate but decreased cardiovascular variability during sleep. Mean BRS increased slightly during CPAP…

Technical details of the hand-sewn and circular-stapled anastomosis in robot-assisted minimally invasive esophagectomy.

2020

SUMMARY The circular mechanical and hand-sewn intrathoracic anastomosis are most often used in robot-assisted minimally invasive esophagectomy (RAMIE). The aim of this study was to describe the technical details of both techniques that were pioneered in two high volume centers for RAMIE. A prospectively maintained database was used to identify patients with esophageal cancer who underwent RAMIE with intrathoracic anastomosis. The primary outcome was anastomotic leakage, which was analyzed using a moving average curve. For the hand-sewn anastomosis, video recordings were reviewed to evaluate number of sutures and distances between the anastomosis and the longitudinal staple line or gastric c…

Surgical robotics for esophageal cancer

2018

We present an update on robotic techniques and their advantages and use in esophageal cancer surgery. Recent work has shown tremendous progress in robotic-assisted minimally invasive esophagectomy (RAMIE) and lymphadenectomy for esophageal cancer, as well as benefits of robotic surgery in high upper esophageal tumors and T4b disease. We discuss the different RAMIE techniques, especially for intrathoracic anastomosis. The ongoing ROBOT trial had demonstrated superiority of robotic esophageal cancer surgery over open esophagectomy. There are various putative technical advantages of RAMIE over minimally invasive esophagectomy, which need to be proven in future trials.

P123 ROBOT ASSISTED MINIMALLY INVASIVE ESOPHAGECTOMY (RAMIE4) WITH INTRATHORACIC ANASTOMOSIS: PROMISING RESULTS AND LESSONS LEARNED IN 100 PATIENTS

2019

Abstract Aim The aim of this study was to describe postoperative complications and short-term oncologic outcomes for RAMIE4 with intrathoracic anastomosis for esophageal cancer within our case series of 100 consecutive patients. Background & Methods Robot assisted minimally-invasive esophagectomy (RAMIE) with intrathoracic anastomosis is gaining popularity as a treatment for esophageal cancer. In this study, we present the results of 100 RAMIE procedures using the da Vinci Xi robotic system (RAMIE4). The aim of this study was to describe postoperative complications and short-term oncologic outcomes for RAMIE4 within our case series of 100 consecutive patients. Between January 2017 and F…

Intrathoracic goitre: A literatura review

2010

Intrathoracic goitre is defined as that goitre which is partially or totally found in the anterior or posterior mediastinum, and its incidence is associated with multinodular goitre. The diagnosis is relatively easy, mainly with imaging tests, and treatment varies, but of choice, surgical treatment is recommended. This article attempts to present a review of the literature on the diagnosis and management of this disease.
