The most common complication after implantation of foreign material is infection, leading to implant failure and severe patient discomfort. Smoldering-infections proceed inapparently and might not get verified by radiological diagnostics. Early identification of this type of infection might significantly reduce the rate of complications. Therefore, we manufactured a microsensor strip in a hybrid of thin-film and laminate technology in a wafer-level process. It comprises electrochemical, amperometric microsensors for glucose, oxygen and lactate as well as an integrated reference electrode...

Inflammatory bowel disease (IBD) is the consequence of an aberrant hemostasis of the immune cells at the gut mucosal border. Based on clinical manifestation, laboratory tests, radiological studies, endoscopic and histological features, this disease is divided into three main types including Crohn's disease (CD), Ulcerative colitis (UC), and IBDunclassified (IBD-U). IBD is frequently presented in adults, but about 20% of IBD cases are diagnosed during childhood called pediatric IBD (PIBD). Some patients in the latter group emerge the first symptoms during infancy or under 5 years of age named infantile and very early onset IBD (VEO-IBD), respectively...

OBJECTIVES: Lung cancer typically starts as a near-spherical lesion, but as it grows it may acquire an irregular radiologic formation. RECIST is based on the assumption that tumors are spherical, and consequently, proportional changes of tumor volume and parallel changes in tumor diameter, and vice versa. Hence, a 30% decrease in diameter (2r) implies a 65% decrease of volume, and a 20% increase in diameter implies a 73% increase of volume. MATERIALS AND METHODS: We compared volumetric measurement based on multi-detector CT technology with calculated volume (CV) according to RECIST in a cohort of 43 patients with advanced, non-squamous cell type, lung cancer treated with a combination of platinum and pemetrexed...

OBJECTIVE: Simulation-based education has been shown to be an effective tool to teach foundational technical skills in various surgical specialties. However, most of the current simulations are limited to generic scenarios and do not allow continuation of the learning curve beyond basic technical skills to prepare for more advanced expertise, such as patient-specific surgical planning. The objective of this study was to evaluate the current medical literature with respect to the utilization and educational value of patient-specific simulations for surgical training...

Cardiac computed tomography angiography (CCTA) is a commonly used diagnostic tool for cardiovascular disease. Despite constant improvements to imaging technologies, the radiation dose to patients from CCTA remains a concern when using this procedure. There remains a need for optimisation of CCTA procedures and accurate dose monitoring to reduce the potential risk of cancer. Establishing diagnostic reference levels (DRLs) allows for the assessment of radiation dose variations, enabling strategies aimed at standardising doses across radiological centres...

Formerly defined "critical values", the importance of critical results (CRs) management in patient care has grown in recent years. According to the George Lundberg definition the result becomes "critical" when, exceeding actionable thresholds, it suggests imminent danger for the patient, unless appropriate therapy is initiated promptly. As required in most important accreditation standards, such as the ISO:15,189 or the Joint Commission standards, a quality reporting system should deliver the correct result to the appropriate clinician in a time-frame that ensures patient safety...

The survival rate of patients with congenital heart disease (CHD) has dramatically improved over the last 2 decades because of technological and surgical advances in diagnosis and treatment, respectively. The vast majority of CHD patients are, in fact, amenable to treatment by either device closure or surgery. Considering the wide spectrum of surgical procedures and complex native and derived anatomy, continuous and detailed follow-up is of paramount importance. Cardiac magnetic resonance and cardiac computed tomography angiography are the cornerstones of diagnosis and follow-up of CHD, allowing for comprehensive noninvasive assessment of the heart, coronary tree, and intrathoracic great vessels, along with both morphological and functional evaluation...
