Association between polyunsaturated fatty acids in adipose tissue and mortality of colorectal cancer patients.

Introduction: Nutritional intake and dysregulation of fatty acid metabolism play a role in the progression of various tumors, but the consumption of fatty acids is difficult to assess accurately with dietary questionnaires. Biomarkers can objectively assess intake, storage and bioavailability.

Objective: We studied the association between the polyunsaturated fatty acid (PUFA) composition of abdominal subcutaneous adipose tissue (good indicator of dietary intake over 2-3 years) and all-cause mortality.

Long-term outcomes of robotic ventral mesh rectopexy for external rectal prolapse.

Introduction: Nowadays in Europe, laparoscopic ventral mesh rectopexy is the gold standard treatment of external rectal prolapse (ERP). The benefits of robot ventral mesh rectopexy (RVMR) are not clearly defined. The primary objective of the study was to evaluate the long-term results of RVMR.

Fatty acid composition of adipose tissue and colorectal cancer: a case-control study.

Background: Unlike experimental results, epidemiologic studies that used dietary questionnaires were not convincing as regards the relations between dietary fatty acids (FAs) and risk of colorectal cancer (CRC). The FA composition of adipose tissue, which is considered to be an indicator of dietary intake over 2-3 y because of the slow turnover rate, appears promising but has so far been rarely used to explore the relation between CRC and exogenous or endogenously produced FAs.

Objective: In this case-control study, we aimed to investigate associations between risk of CRC and the FA composition of subcutaneous adipose tissue and product-to-precursor ratios as indexes of enzymatic activities.

A case-control study of pre-operative levels of serum neutrophil gelatinase-associated lipocalin and other potential inflammatory markers in colorectal cancer.

Background: Chronic inflammation is a key feature of colorectal cancer (CRC), meaning that inflammatory biomarkers may be useful for its diagnosis. In particular, high neutrophil gelatinase-associated lipocalin (NGAL) expression has been reported in CRC. Thus, we investigated whether serum NGAL and NGAL/MMP-9 could be potential biomarkers for the early detection of CRC.

Preoperative adipocytokines as a predictor of surgical infection after colorectal surgery: a prospective survey.

Background: Infections are the leading cause of morbidity and mortality after colorectal surgery. Obesity is a well-known risk factor for wound infection, but it does not seem to increase the risk of other infectious complications. The aim of this study was to look for a relationship between the fatty tissue metabolism measured by adipocytokine levels and the risk of postoperative infection.

Long-term outcomes of robot-assisted laparoscopic rectopexy for rectal prolapse.

Background: Robot-assisted laparoscopic rectopexy for total rectal prolapse is safe and feasible. Small series proved clinical and functional short-term results comparable with conventional laparoscopy. No long-term results have been reported yet.
