BackgroundThe interaction between sleep and the immune system has been increasingly studied over the last decades. The aim of this study was to investigate the association between sleep quality and mucosal healing in patients with inflammatory bowel disease (IBD) currently in clinical remission.MethodsNinety patients with IBD in clinical remission were studied: 54 (60%) with Crohn’s disease and 36 (40%) with ulcerative colitis. All completed the Pittsburgh Sleep Quality Index, and mucosal healing was estimated with ileocolonoscopy. A subgroup analysis was also performed in order to investigate these associations in Crohn’s disease and ulcerative colitis separately.ResultsOf the 90 patients, 45.56% had poor sleep quality. Patients without mucosal healing expressed higher absolute values of the Pittsburgh Sleep Quality Index (P<0.001), while absence of mucosal healing and poor sleep quality were statistically associated (P<0.05). Subgroup analysis showed that the same pattern was present in patients with Crohn’s disease: patients without mucosal healing expressed higher absolute values of the Pittsburgh Sleep Quality Index (P<0.001) and the absence of mucosal healing was statistically associated with poor sleep quality (P<0.05). However, these associations were not observed in the subgroup of patients with ulcerative colitis (P>0.05).ConclusionIn patients with IBD in clinical remission, absence of mucosal healing seems to be associated with poor sleep quality, especially in patients with Crohn’s disease.

B-thalassemic major patients with preserved left ventricular systolic function had impaired left atrial function at the longitudinal axis and left ventricular function at the radial axis. The new echo markers have better prognostic value than the traditional echo indexes in detecting latent diastolic dysfunction in β-thalassemia major, earlier than E/E' ratio.

Abstract. K-ras oncogene is a key factor in colorectal cancer.

Background Concomitant nonbismuth quadruple therapy is recommended as first-line treatment for Helicobacter pylori infection in high clarithromycin resistance areas, but the ideal duration of the regimen remains elusive. Aim of this study was to assess the efficacy and tolerability of 10- versus 14-day concomitant therapy for H. pylori eradication in an area of high clarithromycin and low dual clarithromycin/metronidazole resistance. Methods This was a prospective, open-label study including adult patients with H. pylori infection without previous treatment, from September 2014 to June 2017. Concomitant therapy consisting of pantoprazole 40 mg, amoxicillin 1g, clarithromycin 500 mg, and a nitroimidazole 500 mg was administered twice daily for 10 days in the first phase and for 14 days in the second phase of the study. Efficacy and side effects were compared between groups using chi-square and Fisher’s exact tests. Results In per protocol analysis, rates of eradication for the 10- and 14-day regimen were 91.9% (114/124) and 90.9% (110/121), respectively (P = 0.77). In intention to treat analysis, rates of eradication were lower than 90%. Specifically, rates were 86.3% (114/132) for the 10-day regimen and 85.2% (110/129) for the 14-day regimen (P = 0.8). Side effects, present in 31.3% of treated patients, were significantly more common in the 14-day group (P = 0.015). Four patients discontinued treatment, all in the 14-day group. Conclusions Ten day concomitant nonbismuth quadruple therapy for H. pylori is highly efficacious and better tolerated than the 14-day regimen. Thus, 10-day therapy may be preferred as first-line treatment in clinical practice.
