Does preoperative diabetes mellitus affect weight loss outcome after biliopancreatic diversion with duodenal switch?

BACKGROUND: Preoperative type 2 diabetes mellitus (T2 DM) has previously been reported as an independent predictor for suboptimal (≤40%) weight loss after Roux-en-Y gastric bypass in patients with T2 DM compared with patients who do not have T2 DM. This association has not been shown to apply to patients who undergo biliopancreatic diversion with duodenal switch (BPD/DS). BPD/DS is currently the m...

Novel structural descriptors for automated colon cancer detection and grading.

The histopathological examination of tissue specimens is necessary for the diagnosis and grading of colon cancer. However, the process is subjective and leads to significant inter/intra observer variation in diagnosis as it mainly relies on the visual assessment of histopathologists. Therefore, a reliable computer-aided technique, which can automatically classify normal and malignant colon samples...

Effect of uterine size on fertility of lactating dairy cows.

There are multiple reasons for reduced fertility in lactating dairy cows. We hypothesized that one cause of reduced fertility could be the overall siz...

The rate of mucosal healing by azathioprine therapy and prediction by artificial systems.

BACKGROUND/AIMS: We aimed to assess the effect of azathioprine on mucosal healing in patients with inflammatory bowel diseases (IBD). Artificial neura...

Oncologic Long-Term Results of Robot-Assisted Minimally Invasive Thoraco-Laparoscopic Esophagectomy with Two-Field Lymphadenectomy for Esophageal Cancer.

BACKGROUND: Open transthoracic esophagectomy is the worldwide gold standard in the treatment of resectable esophageal cancer. Robot-assisted minimally...

Design of wormlike automated robotic endoscope: dynamic interaction between endoscopic balloon and surrounding tissues.

BACKGROUND: The current design of capsule endoscope is limited by the inability to control the motion within gastrointestinal tract. The rising incide...

Demonstration of nasopharyngeal surgery with a single port operator-controlled flexible endoscope system.

BACKGROUND: Nasopharyngeal surgery is commonly performed with a rigid endoscope using a transnasal or transoral approach. Here, we demonstrate a flexi...

Inhibitory activity of extracts of Hebridean brown seaweeds on lipase activity.

The effect of three Hebridean brown seaweeds on lipase activity was assessed using a turbidimetric lipase activity assay and an in vitro simulation of...

The learning curve in robotic distal pancreatectomy.

No data are available on the learning curve in robotic distal pancreatectomy (RADP). The learning curve in RADP was assessed in 55 consecutive patient...

Short-term clinical outcomes of robot-assisted intersphincteric resection and low rectal resection with double-stapling technique for cancer: a case-matched study.

Seasonal variation in onset and relapse of IBD and a model to predict the frequency of onset, relapse, and severity of IBD based on artificial neural network.

BACKGROUND: Previous research has yielded conflicting data as to whether the natural history of inflammatory bowel disease follows a seasonal pattern....

Correlation of esophageal clearance and dysphagia symptom assessment after treatment for achalasia.

BACKGROUND: Early relapse after treatment of achalasia occurs in 10-32 % of patients. The best method to follow up these patients is not known. Sympto...

Natural language processing as an alternative to manual reporting of colonoscopy quality metrics.

BACKGROUND AND AIMS: The adenoma detection rate (ADR) is a quality metric tied to interval colon cancer occurrence. However, manual extraction of data...

Cigarette smoke condensate and individual constituents modulate DNA methyltransferase expression in human liver cells.

OBJECTIVES: Previous studies found higher expression levels of DNA methyltransferase 1 in liver samples from smokers compared to those from non-smoker...

Transaxillary thyroidectomies: a comparative learning experience of robotic vs endoscopic thyroidectomies.

OBJECTIVE: Robotic and endoscopic approaches have become more accepted in thyroid surgery, with current literature documenting the experience of high-...
