Background: This study aimed to examine the correlation between subcutaneous fat thickness and chemoport-related infection and to determine the risk factors that lead to complications associated with chemoport.
Methods: This study retrospectively reviewed 363 patients with chemoport insertion between May 2018 and May 2022. The patients were classified into three groups, with 121 patients in each group, based on the tertiles of subcutaneous fat thickness measured in the computed tomography (CT) scan. The incidence of short-term and long-term complications, including dislocation, infection, and malfunction, were obtained and compared between the three groups. The risk factors of chemoport-related complications were analysed in multivariate analysis.
Results: The incidence of infection in the low, middle, and high subcutaneous fat thickness groups were 1.7%, 3.3%, and 0%, respectively ( = 0.131). No short-term complications occurred in this study group. After one year of follow-up, 11 patients (3.0%) had long-term complications; 6 patients (1.7%) developed chemoport infection, while five patients (1.4%) had chemoport dislocation. In multivariate analysis, the risk of dislocation was significantly higher when insertion was performed via the left internal jugular vein (OR = 9.87, =0.033).
Conclusions: The thickness of subcutaneous fat does not significantly correlate with the incidence of chemoport infection, and placement of the port on the left side of the chest wall via the left internal jugular vein is the risk factor for chemoport dislocation.

Steatotic liver disease (SLD) represents a multisystem disease and is a common complication of childhood obesity. We studied fat content at the abdominal level (liver, subcutaneous, and visceral) and the response to childhood obesity management. In this retrospective longitudinal study, 8-18-year-olds with a body mass index (BMI) z-score above 1.

Fatty acid can potentially serve as biomarker for evaluating metabolic disorder and inflammation condition, and quantifying the double bonds is the key for revealing fatty acid information. This study presents an assessment of a deep learning approach utilizing deep image prior (DIP) for the quantification of double bonds and methylene-interrupted double bonds of triglyceride derived from chemical-shift encoded multi-echo gradient echo images, all achieved without the necessity for network training. The methodology implemented a cost function grounded in signal constraints to continually refine the neural network's parameters on a single slice of images through iterative processes.

Background: Deep learning (DL)-based adipose tissue segmentation methods have shown great performance and efficacy for adipose tissue distribution analysis using magnetic resonance (MR) images, an important indicator of metabolic health and disease. The aim of this study was to evaluate the reproducibility of whole-body adipose tissue distribution analysis using proton density fat fraction (PDFF) images at different MR strengths.
Methods: A total of 24 volunteers were imaged using both 1.

Background: With rising demand for non-invasive body contouring, this study aimed to evaluate the efficacy and safety of non-focused, low-intensity ultrasound for lower abdominal lipolysis.
Methods: The enrolled subjects prospectively received 6 weekly sessions of well-setting ultrasound treatment with frequency of 1 MHz and an intensity of 2.2 W/cm2, to target the subcutaneous fat of lower abdomen with three regions (left, middle, and right).

Objectives: To investigate baseline patient characteristics associated with the risk of computed tomography (CT)-based sarcopenia and assess whether sarcopenia and other morphometric parameters influence survival outcomes in patients with liver metastases and cholangiocarcinoma after Yttrium-90 radioembolization.
Materials And Methods: We retrospectively analyzed 120 cancer patients (mean age, 62 ± 13.3 years, 61 men) who underwent preprocedural CT.
