BACKGROUND: Metabolic risk factors associated with non-alcoholic fatty liver disease (NAFLD) include Type 2 diabetes mellitus (T2DM), obesity and dyslipidaemia. Prevention or management of these risk factors with glycaemic control, weight reduction and low serum lipid levels respectively have been reported to reduce the risk of NAFLD or slow its progression. Since ultrasound (USS) is a safe and reliable method of identifying fatty changes in the liver, this study was done to determine the relationship between glycaemic control and ultrasound diagnosed NAFLD in T2DM...

The problem of endocrine disrupting compounds (EDCs) in the environment has become a worldwide concern in recent decades. Besides their toxicological effects at low concentrations and their widespread use in industrial and household applications, these pollutants pose a risk for non-target organisms and also for public safety. Analytical methods to determine these compounds at trace levels in different matrices are urgently needed. This review critically discusses trends in analytical methods for well-known EDCs like alkylphenols and bisphenol A in solid environmental matrices, including sediment and aquatic biological samples (from 2006 to 2018)...

In juvenile idiopathic arthritis (JIA), imaging is increasingly used in clinical practice. In this paper we discuss imaging of the knee, the clinically most commonly affected joint in JIA. In the last decade, a number of important steps have been made in the development of imaging outcome measures in children with JIA knee involvement. Ultrasound is undergoing a fast validation process, which should be accomplished within the next few years. The validation processes of MRI as an imaging biomarker for clinical trials in the JIA knee are at an advanced stage, with important data available on the feasibility, reliability and validity of the Juvenile Arthritis MRI Scoring system...

OBJECTIVES: Studies have shown that common carotid intima media thickness (CIMT) measured by B-mode sonography increases with body mass index (BMI) among subjects with cardiovascular diseases in different populations. However, association of body fat and subclinical atherosclerosis in the absence of these cardiovascular diseases is understudied. We aimed to evaluate the correlation between BMI and CIMT in a healthy adult population of black African ancestry. METHODS: This is a cross-sectional prospective study in 300 consecutive apparently healthy subjects aged 18 to 70 years without history of hypertension, dyslipidemia, diabetes mellitus, and renal disease...

Chest ultrasonography (CU) is a noninvasive imaging technique able to provide an immediate diagnosis of the underlying aetiology of acute respiratory failure and traumatic chest injuries. Given the great technologies, it is now possible to perform accurate CU in remote and adverse environments including the combat field, extreme sport settings, and environmental disasters, as well as during space missions. Today, the usage of CU in the extreme emergency setting is more likely to occur, as this technique proved to be a fast diagnostic tool to assist resuscitation manoeuvres and interventional procedures in many cases...

We propose a column-row-parallel imaging front-end architecture for integrated and low-power 3-D medical ultrasound imaging. The column-row-parallel architecture offers linear-scaling interconnection, acquisition, and programming time with row-by-row or column-by-column operations, while supporting volumetric imaging functionality and fault-tolerance against possible transducer element defects with per-element controls. The combination of column-parallel selection logic, row-parallel selection logic, and per-element selection logic reaches a balance between flexible imaging aperture definition and manageable imaging data/control interface to a 2-D array...

RATIONALE: Complete loss of splenic function increases infection and cardiovascular disease risks, so there is growing emphasis on spleen-preserving treatments, such as laproscopic partial splenectomy (LPS). However, LPS carries higher risk for hemorrhage. Sequential splenic embolization can obliterate the perilesional vascular bed while preserving flow through healthy tissue, substantially reducing risk of uncontrolled hemorrhage during LPS. Preoperative partial splenic embolization (PSE) may soften the spleen and reduce its size, which enhances space exposure for laparoscopic operation...

Bioinert gold nanoparticles of various shapes and functionalities are widely accepted as contrast agents (CAs) for several modalities of imaging, viz., electron microscopy, computerized tomography (CT), X-ray and photoacoustic (PA) imaging. However, testing of novel compact-imaging probes for ocular diagnostic imaging is always challenging. Here, ultra-fast microwave oven synthesized gold nanocages (AuNcgs) were successfully demonstrated for high-contrast PA ocular imaging for the first time. Methods are described for the synthesis, characterization and application of quickly synthesized AuNcgs in diagnostic ocular imaging...
