A Framework for Automatic Morphological Feature Extraction and Analysis of Abdominal Organs in MRI Volumes

AbstractThe accurate 3D reconstruction of organs from radiological scans is an essential tool in computer-aided diagnosis (CADx) and plays a critical role in clinical, biomedical and forensic science research. The structure and shape of the organ, combined with morphological measurements such as volume and curvature, can provide significant guidance towards establishing progression or severity of a condition, and thus support improved diagnosis and therapy planning. Furthermore, the classification and stratification of organ abnormalities aim to explore and investigate organ deformations following injury, trauma and illness. This paper presents a framework for automatic morphological feature extraction in computer-aided 3D organ reconstructions following organ segmentation in 3D radiological scans. Two different magnetic resonance imaging (MRI) datasets are evaluated. Using the MRI scans of 85 adult volunteers, the overall mean volume for the pancreas organ is 69.30 ± 32.50cm3, and the 3D global curvature is (35.23 ± 6.83) × 10−3. Another experiment evaluates the MRI scans of 30 volunteers, and achieves mean liver volume of 1547.48 ± 204.19cm3 and 3D global curvature (19.87 ± 3.62) × 10− 3. Both experiments highlight a negative correlation between 3D curvature and volume with a statistical difference (p

This study was designed to investigate the association of rs7903146 (C/T) polymorphism of TCF7L-2 gene with non-alcoholic fatty liver disease (NAFLD) in Asian Indians.MethodsIn this case-control study 162 non-diabetic subjects with NAFLD and 173 body mass index (BMI)-matched controls without NAFLD were recruited. Abdominal ultrasound, clinical and biochemical investigations, fasting insulin levels and value of homeostasis model assessment of insulin resistance (HOMA-IR) was measured. Single nucleotide polymorphism rs7903146 (C/T) was genotyped by polymerase chain reaction–restriction fragment length polymorphisms.Res...

CONCLUSION: MS is beneficial where the main aim is to attain a significant and long-lasting weight loss results. The RCTs have depicted the superiority which surgical mechanisms hold over medically based therapy, for enhancing glycaemic control, and achieving remission of diabetes. This type of surgery improves life quality, reduces incidences of other obesity and diabetes relating diseases like microvascular illness, sleep apnea, fatal disorder, and fatty liver disease.

Authors: Grgurevic I, Podrug K, Mikolasevic I, Kukla M, Madir A, Tsochatzis EA Abstract Nonalcoholic fatty liver disease (NAFLD) is becoming the most prevalent liver disease worldwide, associated with epidemics of overweight and resulting metabolic syndrome (MetS). Around 20-30% of patients with NAFLD develop progressive liver fibrosis, which is the most important predictor of liver-related and overall morbidity and mortality. In contrast to classical understanding, no significant association has been demonstrated between the inflammatory component of NAFLD, i.e., nonalcoholic steatohepatitis (NASH), and the advers...

Nonalcoholic fatty liver disease (NAFLD) is an increasingly recognized public health problem, affecting up to a quarter of the world's adult population. The burden of NAFLD is influenced by the epidemics of obesity and type 2 diabetes mellitus (T2DM) and the prevalence of these conditions is not expected to decrease in the forthcoming decades. Consequently, the burden of NAFLD-related liver complications (non-alcoholic steatohepatitis [NASH], cirrhosis and hepatocellular carcinoma) and the need for life-saving liver transplantation are also expected to increase further in the near future.

ConclusionThe health economic models identified in this review are associated with limitations primarily driven by a lack of NASH-specific data. Identified models also largely overlooked the intricate association between NASH and other conditions, including obesity and T2DM, and did not capture the increased risk of cardiovascular events associated with NASH. High-quality, transparent, validated health economic models of NASH will be required to evaluate the cost effectiveness of treatments currently in development, particularly compounds that may target other non-hepatic outcomes.

In the 1970s and 1980s, the monosaccharide fructose, because of its low glycemic effect, attracted much interest as a potential sweetener for patients with diabetes mellitus (1). Many decades later, its widespread use in the food supply, both as a component of sucrose as well as in high-fructose corn syrup, has become a major suspect in the current epidemic of obesity, type 2 diabetes mellitus, nonalcoholic fatty liver disease, and cardiovascular diseases (2).

Purpose of review In this review, authors have selected from literature the most recent and suggestive studies on therapy of nonalcoholic fatty liver disease (NAFLD). The selected interventions regulate the action of gastrointestinal peptides, such as gastric inhibitory polypeptide (GIP), nesfatin, peptide YY, cholecystokinin, and glucagon-like peptide 1 (GLP-1). These hormones have been found frequently modified in obesity and/or type 2 diabetes mellitus, morbidities mostly associated with NAFLD. This disease has a very high prevalence worldwide and could evolve in a more severe form, that is, nonalcoholic steatohepatit...

Metabolic syndrome (MetS) is a public health problem of great impact and significance. MetS is generally defined as a grouping of abdominal obesity, impaired glucose metabolism, dyslipidemia and hypertension and has an estimated national prevalence of approximately 34% [1,2]. The presence of MetS has been previously found to confer numerous adverse long-term health consequences, including an increased risk for cardiovascular disease, the development of type 2 diabetes mellitus, fatty liver disease and cancer [3 –6].

PfeifferAbstractGIP was proposed to play a key role in the development of non- alcoholic fatty liver disease (NAFLD) in response to sugar intake. Isomaltulose, is a 1,6-linked glucose-fructose dimer which improves glucose homeostasis and prevents NAFLD compared to 1,2-linked sucrose by reducing glucose-dependent insulinotropic peptide (GIP) in mice. We compared effects of sucrose vs. isomaltulose on GIP and gluca...
