Abstract Aims To describe the overall fat distribution patterns independent of body mass index (BMI) in participants with type 2 diabetes (T2D) SURPASS‐3 MRI substudy by comparison sex‐ and BMI‐matched virtual control groups (VCGs) derived from UK Biobank imaging study at baseline Week 52. Methods For each participant 52 ( N = 296), a VCG ≥150 same sex similar BMI was identified 40 172). Average visceral adipose tissue (VAT), abdominal subcutaneous (aSAT) liver (LF) levels observed standard...
Abstract Objective Fat distribution pattern could help determine cardiometabolic risk profile. This study aimed to evaluate the association of balance/imbalance between visceral adipose tissue (VAT), abdominal subcutaneous (aSAT), and liver fat (LF) with incident type 2 diabetes (T2D) cardiovascular disease (CVD) in UK Biobank prospective cohort study. Methods Magnetic resonance images 40 174 participants were analyzed for VAT, aSAT, LF using AMRA® Researcher. To assess patterns independent...
Abstract Background Symptomatic spinal stenosis is a prevalent complication in adults with achondroplasia. Increased muscle fat infiltration (MFI) and reduced thigh volumes have also been reported, but the pathophysiology poorly understood. We explored whether increased MFI were associated presence of symptomatic physical functioning. Methods assessed by MRI 40 achondroplasia, compared to 80 average-statured controls, matched for BMI, gender, age. In achondroplasia participants, six-minute...
There seems to be a correlation between early gut microbiota composition and postnatal immune development. Alteration in the microbial life has been associated with mediated diseases, such as autoimmunity allergy. We have previously observed associations presence of lactobacilli Staphylococcus (S.) aureus early-life microbiota, cytokine responses allergy development children. Consistent objective understand how bacteria modulate response intestinal epithelial cell (IEC) lines cells, we...
Non-linearly perturbed discrete time regenerative processes with stopping times are considered. We define the quasi-stationary distributions for such and present conditions their convergence. Under some additional assumptions, can be expanded in asymptotic power series respect to perturbation parameter. give an explicit recurrence algorithm calculating coefficients these expansions. Applications alternating absorption risk presented.
Sarcopenia is common in end-stage liver disease and negatively impacts patients awaiting or undergoing transplantation (LT). Magnetic resonance imaging (MRI) may be used to measure body composition sarcopenia. We aimed evaluate the feasibility of MRI-based LT profiling, describe waitlist composition, assess natural rate change while on post-LT.
We consider a discrete time semi-Markov process where the characteristics defining depend on small perturbation parameter. It is assumed that state space consists of one finite communicating class states and, in addition, absorbing state. Our main object interest asymptotic behavior joint probabilities position and event non-absorption as tends to infinity parameter zero. The result gives exponential expansions these together with recursive algorithm for computing coefficients expansions. An...
Background: The link between type 2 diabetes (T2D) and muscle health is not fully understood. Magnetic resonance imaging allows detection of Adverse composition (MC).Method: Thigh fat-free volume (FFMV, higher better) fat infiltration (MFI, worse) was measured in 38974 UK Biobank participants using AMRA Researcher. Persons with T2D (N=1881) were divided into four MC groups: (1) Normal MC, (2) Only low (FFMV z-score < the population wide 25th percentile (sex BMI invariant)), (3) high (MFI >...
Abstract Background Sarcopenia is a prevalent condition in patients on maintenance hemodialysis and associates with mortality. Research using magnetic resonance imaging (MRI) has demonstrated the importance of proper body size-adjustment assessment muscle mass, that composition including measurements both volume fat infiltration improves prediction comorbidity survival related to sarcopenia. Such combined not previously been performed patients. Methods Eleven were scanned whole-body water...
