BACKGROUND: Some solitary pulmonary nodules (SPNs) as early manifestations of lung cancer, it is difficult to determine its nature, which brings great trouble to clinical diagnosis and treatment. Radiomics can deeply explore the essence of images and provide clinical decision support for clinicians. The purpose of our study was to explore the effect of positron emission tomography (PET) with 2-deoxy-2-[fluorine-18] fluoro-d-glucose integrated with computed tomography (CT; 18 F-FDG-PET/CT) combined with radiomics for predicting probability of malignancy of SPNs...

Current advancements in neuromorphic computing systems are focused on decreasing power consumption and enriching computational functions. Correspondingly, state-of-the-art system-on-chip developers are encouraged to design nanoscale devices with minimum power dissipation and high-speed operation. This paper deals with designing a sense amplifier based on side-contacted field-effect diodes to reduce the power-delay product (PDP) and the noise susceptibility, as critical factors in neuron circuits. Our findings reveal that both static and dynamic power consumption of the S-FED-based sense amplifier, equal to 1...

Introduction Abdominal angiography procedures such as transarterial chemoembolization (TACE) are essential for hepatocellular carcinoma treatment. One method commonly used is transfemoral access (TFA). However, issues associated with this method, which include postoperative compression of the puncture site and long periods of bed rest, can affect patient satisfaction. Thus, transradial access (TRA), a minimally invasive treatment method that improves treatment quality, was developed for TACE. This retrospective, multicenter study aimed to investigate the efficacy and safety of abdominal angiography using the radial artery approach...

BACKGROUND: Implant-based breast reconstruction is the most prevalent form of breast reconstruction. Autologous fat grafting (AFG) was conceptualized as an alternative to implant-based breast reconstruction and was found to be a reliable reconstruction modality. However, usually, a few grafting rounds are required to create the desired shape and size of the breast. Current literature describes ample experience with AFG as an adjunct to implant-based breast reconstruction for improving appearance...

BACKGROUND: The historic morbidity and mortality rates of anti-reflux and hiatal hernia surgery are reported as 3-21% and 0.2-0.5%, respectively. These data come from either large national/population level or small institutional studies, with the former focusing on broad 30-day outcomes while lacking granular data on complications and their severity. Institutional studies tend to focus on long-term and quality of life outcomes. Our objective is to describe and evaluate the incidence of 30 and 90-day morbidity and mortality in a large, single institution dataset...

Infantile dystonia-parkinsonism type 2 (PKDYS2) is a rare inherited autosomal recessive movement disorder with onset in infancy. The disease is associated with a mutation in the solute carrier family 18 member A2 gene ( SLC18A2 ). There are reports of trials with dopaminergic drugs and the condition of patients given levodopa almost always worsens and dopamine agonists give varying degrees of benefit to some. Here, we report a PKDYS2 patient with a new variant in the SLC18A2 gene who underwent multiple trials of pharmacotherapy...

This work analyses the activities of Genoese merchant communities in the grain trade in western Mediterranean markets.
