Metabolomic profiling of upper GI malignancies in blood and tissue: a systematic review and meta-analysis.

Objective: To conduct a systematic review and meta-analysis of case-control and cohort human studies evaluating metabolite markers identified using high-throughput metabolomics techniques on esophageal cancer (EC), cancer of the gastroesophageal junction (GEJ), and gastric cancer (GC) in blood and tissue.

Background: Upper gastrointestinal cancers (UGC), predominantly EC, GEJ, and GC, are malignant tumour types with high morbidity and mortality rates. Numerous studies have focused on metabolomic profiling of UGC in recent years.

TGFβ signalling pathway impacts brain metastases profiles in locally advanced colorectal cancer.

Rationale: Colorectal Cancer (CRC) represents the third most common type of cancer in Germany and the second most common cancer-related cause of death worldwide. Distant metastases are still the main limit for patient survival. While liver metastases as well as peritoneal carcinomatosis can often either be resected or treated with systemic therapy, little options remain for brain metastases.

Changes in Plasma Metabolomic Profile Following Bariatric Surgery, Lifestyle Intervention or Diet Restriction-Insights from Human and Rat Studies.

Although bariatric surgery is known to change the metabolome, it is unclear if this is specific for the intervention or a consequence of the induced bodyweight loss. As the weight loss after Roux-en-Y Gastric Bypass (RYGB) can hardly be mimicked with an evenly effective diet in , translational research efforts might be helpful. A group of 188 plasma metabolites of 46 patients from the randomized controlled Würzburg Adipositas Study (WAS) and from RYGB-treated ( = 6) as well as body-weight-matched controls ( = 7) were measured using liquid chromatography tandem mass spectrometry.

Endoscopic Management of Clinically Severe Obesity: Primary and Secondary Therapeutic Procedures.

Purpose Of Review: In the treatment of epidemic obesity and metabolic disorders, conservative approaches often fail to achieve the treatment goal in patients with very high BMI. To date, bariatric surgery accomplishes the most sustainable results in patients with morbid obesity. This leads to a treatment gap for lower and middle classes of obesity defined by BMI.
