Abstract
Much is said about precision medicine, but its real significance and the possibility of making it a real possibility is far from certain. Several studies in each of the autoimmune diseases have provided important insight into molecular pathways but the use of molecular studies, particularly those looking into transcriptome pathways, have seldom approached the possibility of using the data for disease stratification and then for prediction, or diagnosis. Only the type I interferon signature has been considered in the use of this signature for therapeutic purposes, particularly in the case of systemic lupus erythematosus. Here, the authors provide an update on precision medicine, what can be translated into clinical practice, and what do single-cell molecular studies provide to our knowledge in autoimmune diseases, focusing on a few examples. The main message being that we should try to move from precision medicine of established disease to preventive medicine in order to predict the development of disease.

Abstract
Ultrasound has an excellent diagnostic performance when Crohn's disease is suspected, when performing an activity assessment, or determining the extension and location of Crohn's disease, very similar to other examinations such as MRI or CT. It has a good correlation with endoscopic lesions and allows the detection of complications such as strictures, fistulas or abscesses. It complements colonoscopy in the diagnosis and, given its tolerance, cost and immediacy, it can be considered as a good tool for disease monitoring. In ulcerative colitis, its role is less relevant, being limited to assessing the extent and activity when it is not possible with other diagnostic techniques or if there are doubts with these. Despite its advantages, its use in inflammatory bowel disease (IBD) is not widespread in Spain. For this reason, this document reviews the advantages and disadvantages of the technique to promote knowledge about it and implementation of it in IBD Units.

Abstract
BACKGROUND In inflammatory bowel disease (IBD) a high percentage of women are diagnosed during their reproductive age. IBD in remission is the ideal scenario when planning a pregnancy. AIMS To describe the clinical characteristics of pregnancy/newborn and assess disease activity at the time of conception and throughout the pregnancy in patients with IBD treated at a tertiary centre in Chile. METHODS We retrospectively reviewed women diagnosed with IBD who were pregnant or delivered between 2017 and 2020. Demographic, clinical, obstetric and delivery data were obtained from the IBD registry, approved by the local IRB. Descriptive statistics and association tests were performed (χ2, p ≤ 0.05). RESULTS Sixty women with IBD were included. At the beginning of pregnancy, 21 (35%) had active disease and 39 (65%) were in remission. Of those with active disease, 16 (66%) remained active and 6 had spontaneous abortions. In those who were in remission, 26 (69%) remained in this condition. Nine patients (15%) discontinued treatment, and 6 of these had inflammatory activity during pregnancy. Preconception counselling was performed in 23 of the 60 patients, being higher in the group that remained in remission during pregnancy (65% vs. 35%, p = 0.02). Patients who had a flare during pregnancy had more probability of preterm birth (<37 weeks) and newborn with lower weight compared with the group that always remained in remission (89% vs. 74%, p = 0.161) and (2.885 vs 3.370 g; p = 0.0014). CONCLUSION Remission presents better outcomes in pregnancy and preconception counselling would allow a better IBD control during pregnancy.

Abstract
INTRODUCTION AND AIMS During the clinical course of inflammatory bowel disease, different causes can compromise kidney, liver, and bone marrow function and increase the risk for osteoporosis, infections, and neoplasias. The aim of the present study was to describe the follow-up of Mexican patients with inflammatory bowel disease in relation to their vaccination regimen, treatment-associated risks, and cancer screening. MATERIALS AND METHODS A retrospective cross-sectional study was conducted within the time frame of February and June 2017. One hundred patients that had a histopathologic diagnosis of inflammatory bowel disease were surveyed about their follow-up vaccination regimen, treatment-associated risks, and cancer screening. SPSS v24 software was employed for the statistical analysis. RESULTS One hundred patients with inflammatory bowel disease were studied (90% with ulcerative colitis and 10% with Crohn's disease; 60% women, 40% men): 75% stated that they had no vaccination regimen. A total of 71.4% of the women had at least one Pap smear in their lives and 28.6% did not have them done annually. Twenty-four percent of the patients wore sun block daily. A total of 18.2% of the patients with more than a 10-year progression of ulcerative colitis had an annual colonoscopy. Yearly kidney function was registered in 57.1% of the patients, 92.9% had a yearly complete blood count, and 78.6% had yearly liver function tests. A total of 34.8% of patients had no bone densitometry in their case records. CONCLUSIONS These results are a red flag suggesting the need to reinforce the role of the primary healthcare providers in relation to vaccination follow-up and the need to improve the education of the patient in relation to inflammatory bowel disease.

Abstract
OBJECTIVE Familial GUCY2C diarrhoea syndrome (FGDS) is caused by an activating mutation in the GUCY2C gene encoding the receptor guanylate cyclase C in enterocytes. Activation leads to increased secretion of fluid into the intestinal lumen. Twenty percent of the patients have increased risk of Crohn's disease and intestinal obstruction (CD, 20%) and the condition resembles irritable bowel syndrome with diarrhoea. We aimed to describe fluid content, contractility, peristaltic activity and bowel wall thickness in the intestine in fasting FGDS patients, using ultrasound, with healthy volunteers serving as controls. METHODS Twenty-three patients with FGDS and 22 healthy controls (HC) were examined with a Logiq E9 scanner in a fasting state. Bowel wall thickness was measured and fluid-filled small bowel loops were counted using three-dimensional (3D) magnetic positioning navigation. The HC ingested 500 ml PEG solution, an electrolyte balanced, non-absorbable solution, in order to investigate the contractions of the small bowel. RESULTS The fasting 23 FGDS patients had significantly higher number of fluid-filled small bowel segments compared to 22 fasting HC, p < 0.001. A high number of non-occlusive contractions in the ileum was observed, which was significant when compared to HC after ingesting PEG solution, p < 0.016. An increase in intestinal wall thickness or other signs of CD were not observed. CONCLUSIONS FGDS is characterised by multiple, fluid-filled small bowel loops with incomplete contractions and fluid stagnation in fasting state. These findings may play a role in the increased risk of bowel obstruction as well as IBS-like symptoms observed in these patients.
