We perform unsupervised analysis of image-derived shape and motion features extracted from 3,822 cardiac Magnetic resonance imaging (MRIs) of the UK Biobank. First, with a feature extraction method previously published based on deep learning models, we extract from each case 9 feature values characterizing both the cardiac shape and motion. Second, a feature selection is performed to remove highly correlated feature pairs. Third, clustering is carried out using a Gaussian mixture model on the selected features. After analysis, we identify 2 small clusters that probably correspond to 2 pathological categories. Further confirmation using a trained classification model and dimensionality reduction tools is carried out to support this finding. Moreover, we examine the differences between the other large clusters and compare our measures with the ground truth.
Although collecting faeces and blood samples are considered non-invasive methods of monitoring Crohn's disease (CD), these methods are less preferred by some patients. This study utilized urine as an alternative to evaluate four disease biomarkers in young adults with active CD before and after exclusive enteral nutrition (EEN) therapy.
Urine samples collected at baseline (W0) and after 8 weeks (W8) of EEN therapy were assayed by ELISA for levels of intestinal fatty acid-binding protein (I-FABP), liver fatty acid-binding protein (L-FABP), claudin-3, and calprotectin. Levels of each biomarker were also compared with standard clinical parameters, including disease indexes, nutrient, and inflammatory markers.
Of the paired urine samples from 14 patients, 10 were female and 12 were newly diagnosed with CD. Urinary I-FABP Cr (standardized to urine Cr) levels were significantly reduced, while urinary L-FABP Cr levels increased following EEN therapy. Urinary L-FABP Cr correlated positively with serum insulin-like growth factor 1 (IGF-1) (
= 0.60,
= 0.02). Urinary CLND3 Cr and calprotectin Cr levels were not significantly different after treatment.
I-FABP is a potential urinary biomarker of disease activity in adults with CD, while urinary L-FABP may be an indirect marker of nutritional status in adults with CD. CLND3 and calprotectin do not appear to have roles as urinary biomarkers in CD. These findings warrant further investigations using a larger sample size.

There is a high degree of perceived stigma among adults with inflammatory bowel disease (IBD), with up to 84% considering a social stereotype against them due to their condition. This may negatively impact their treatment adherence and quality of life, as well as practical issues such as gaining urgent access to public bathroom facilities. It has been demonstrated that higher public knowledge levels can reduce public stigma, yet little is known about the general level of understanding of IBD in the community. selleck products A study was performed to ascertain the public knowledge levels of IBD in Christchurch, New Zealand, using a validated assessment tool.
The aims of this study were to implement a validated knowledge survey (IBD-KID2) among members of the general public in Christchurch, New Zealand, and to assess the level of understanding about IBD.
Recruitment took place at a Health Research and Education showcase event at the University of Otago (Christchurch), which is a free event open to members of the public. knowledge deficiencies among members of the general public in Christchurch, New Zealand. These topics may be addressed with awareness campaigns in order to maximise community support for adults and children with IBD.
Ulcerative colitis (UC) is a subtype of inflammatory bowel disease that can develop extraintestinal manifestations (EIMs) in a subgroup of patients. The aim of this work was to study the frequency and clinical factors associated with the development of EIMs.
We evaluated a total of 260 Mexican patients with confirmed UC who were followed retrospectively in order to identify the factors associated with the presence of EIMs.
The frequency of EIM was 55.8%. The factors associated with the development of EIM were pancolitis (
= 0.003, OR = 2.44, 95% CI = 1.34-4.56) and previous colectomy (
= 0.024, OR = 7.54, 95% CI = 1.20-60.44). A clinical course of initial activity and then long remission for >5 years was found to be a protective factor (
= 0.002, OR = 0.31, 95% CI = 0.14-0.67).
The frequency of EIM was 55.8% in our population, and the factors associated with their development were pancolitis and colectomy; meanwhile, a clinical course of initial activity and then long remission was a protector feature.

Primary care faecal calprotectin (FC) was introduced in Leeds in 2014 to distinguish inflammatory bowel disease (IBD) from irritable bowel syndrome and with the hope that it may reduce time to IBD diagnosis and treatment. This study examines the association of FC with referral routes, time to diagnosis, and time to treatment.
All patients newly referred to IBD clinics in 2013 and 2016 were studied. Data on referral routes and dates, FC, date of first treatment, and proxy outcomes for disease severity were collected.
In 248 patients, there were no differences between 2013 and 2016 cohorts regarding baseline data and disease severity. The number of direct referrals to gastroenterology rose from 3% (2013) to 17% (2016), whilst 10% were diagnosed during emergency admissions. Referrals via suspected cancer pathways remained high (38% in 2013, 28% in 2016), whilst many had initial investigations at independent centres (16% in 2013, 24% in 2016). Time from referral to diagnosis was similar between 2013 (0.77 month) and 2016 (1.
