How to prevent postoperative ileus in colorectal surgery? a systematic review.

Postoperative ileus (PI) after colorectal surgery is a common surgical problem. This systematic review aimed to investigate the available data in the literature to reduce the PI in the area of colorectal surgery out of the enhanced recovery after surgery principles, referring to published randomized controlled trials (RCTs) and meta-analyses, and to provide recommendations according to the Oxford Centre for Evidence-Based Medicine. The authors conducted bibliographic research on 1 December 2022.

Association between dopamine receptor D3 gene BalI polymorphism and cognitive impulsiveness in alcohol-dependent men.

The gene coding for the dopamine receptor D3 (DRD3) is considered as a major candidate gene in various addictive disorders. Association studies in alcohol-dependence for this gene are nevertheless controversial. We made the hypothesis that phenotypical heterogeneity of alcohol-dependence (i.

Family-based association study of the 5-HT transporter gene and schizophrenia.

The gene coding for the 5-HT transporter (5-HTT) is considered as a candidate gene for schizophrenia, because this transporter plays a key role in serotonin neurotransmission. Previous genetic studies focusing on this gene yielded conflicting results, presumably because of stratification biases linked to the case-control association study approach, and the potential genetic and phenotypic heterogeneity of schizophrenia. We investigated the 5-HTTLPR and 17-bp VNTR (variable number of tandem repeats) polymorphisms of this gene in 103 trios using the transmission disequilibrium test.

The 3' region of the DRD2 gene is involved in genetic susceptibility to schizophrenia.

The gene coding for the D2 dopamine receptor (DRD2) is considered as one of the most relevant candidate genes in schizophrenia. Previous genetic studies focusing on this gene yielded conflicting results, for example because of differences in methodology (linkage versus association studies) and variability in the loci analyzed (the DRD2 gene having many polymorphic sites). We used a progressive strategy with two different approaches (case-control and transmission disequilibrium test) and investigated six genetic polymorphisms spanning the DRD2 gene in 103 patients with DSM-IV criteria of schizophrenia, their 206 parents and 83 matched healthy control subjects.
