Infant embodiment and interembodiment

This article brings together a range of research and scholarship from various disciplines which have investigated and theorised social and cultural aspects of infants’ bodies within the context of contemporary western societies. It begins with a theoretical overview of dominant concepts of infants’ bodies, including discussion of the concepts of the unfinished body, civility and the Self/Other binary opposition as well as that of interembodiment, drawn from the work of Merleau-Ponty. Then follows discussion of the pleasures and challenging aspects of interembodiment in relation to caregivers’ interactions with infants’ bodies, purity, danger and infant embodiment and lastly practices of surveilling the vulnerable, ‘at risk’ infant body

Disease activity in inflammatory bowel disease patients is associated with increased liver fat content and liver fibrosis during follow-up

Purpose Liver steatosis is a frequently reported condition in patients with inflammatory bowel disease (IBD). Different factors, both metabolic and IBD-associated, are believed to contribute to the pathogenesis. The aim of our study was to calculate the prevalence of liver steatosis and fibrosis in IBD patients and to evaluate which factors influence changes in steatosis and fibrosis during follow-up. Methods From June 2017 to February 2018, demographic and biochemical data was collected at baseline and after 6-12 months. Measured by transient elastography (FibroScan), liver steatosis was defined as Controlled Attenuation Parameter (CAP) >= 248 and fibrosis as liver stiffness value (Emed) >= 7.3 kPa. IBD disease activity was defined as C-reactive protein (CRP) >= 10 mg/l and/or fecal calprotectin (FCP) >= 150 mu g/g. Univariate and multivariate regression analysis was performed; a p-value of <= 0.05 was considered significant. Results Eighty-two out of 112 patients were seen for follow-up; 56% were male. The mean age was 43 +/- 16.0 years, and mean BMI was 25.1 +/- 4.7 kg/m(2). The prevalence of liver steatosis was 40% and of fibrosis was 20%. At baseline, 26 patients (32%) had an active episode of IBD. Using a multivariate analysis, disease activity at baseline was associated with an increase in liver steatosis (B = 37, 95% CI 4.31-69.35, p = 0.027) and liver fibrosis (B = 1.2, 95% CI 0.27-2.14, p = 0.016) during follow-up. Conclusions This study confirms the relatively high prevalence of liver steatosis and fibrosis in IBD patients. We demonstrate that active IBD at baseline is associated with both an increase in liver steatosis and fibrosis during follow-up.Cellular mechanisms in basic and clinical gastroenterology and hepatolog

Cytokine Mixtures Mimicking the Local Milieu in Patients with Inflammatory Bowel Disease Impact Phenotype and Function of Mesenchymal Stromal Cells

Locally applied mesenchymal stromal cells (MSCs) have the capacity to promote the healing of perianal fistulas in Crohn's disease (CD) and are under clinical development for the treatment of proctitis in ulcerative colitis (UC). Despite these clinical advances, the mechanism of action of local MSC therapy in inflammatory bowel disease (IBD) is largely unknown. We hypothesized that the local cytokine environment in IBD patients affects the immunomodulatory properties of MSCs. To evaluate this, 11 cytokines were analyzed in inflamed tissues obtained from CD and UC patients. Based on the identified cytokine profiles 4 distinct cytokine mixtures that mimic various inflammatory IBD environments were established. Next, MSCs were cultured in the presence of either of these 4 cytokine mixtures after which the expression of immunomodulatory and tissue regenerative molecules and the capacity of MSCs to modulate T-cell proliferation and dendritic cell (DC) differentiation were assessed. Our data show that MSCs respond, in a cytokine-specific manner, by upregulation of immunomodulatory and tissue regenerative molecules, including cyclooxygenase-2, indoleamine 2,3-dioxygenase, and transforming growth factor-beta 1. Functional studies indicate that MSCs exposed to a cytokine profile mimicking one of the 2 UC cytokine milieus were less effective in inhibition of DC differentiation. In conclusion, our data indicate that cytokine mixes mimicking the local cytokine milieus of inflamed UC colonic or CD fistulas tissues can differentially affect the immunomodulatory and tissue regenerative characteristics of MSCs. These data support the hypothesis that the local intestinal cytokine milieu serves as a critical factor in the efficacy of local MSC treatment.Cellular mechanisms in basic and clinical gastroenterology and hepatolog
