Summary: Evaluation of body composition is crucial for assessing nutritional status. Various methods for body composition measurement have been developed, but they may produce different results due to different principles and biases. The use of statistical methods to compare the data obtained by different techniques has led to further biases. This review summarizes the most commonly used methods for body composition measurement in clinical practice and provides suggestions for interpreting data using statistical methods, as well as highlighting pitfalls and limitations.

Summary: Insight into body composition using bioelectric impedance analysis (BIA) is valuable in the ICU setting, but its validity and interpretation in critically ill patients remain uncertain. Correlations have been found between BIA parameters and adverse outcomes in critical illness, but cut-off values and reference standards are still unclear, necessitating further research and validation.

Summary: Electrical bioimpedance is a spectroscopic technique used for measuring the electrical properties of tissues based on frequency. This tutorial covers the basics of sensor design, including electrode/electrolyte interface, equivalent circuit modeling, and sensitivity theorem. It also discusses analytical and numerical modeling approaches for electric field simulations and current trends in bioimpedance sensors.

Summary: This study aims to evaluate the accuracy of a new method that combines CT imaging data with automatic software and artificial intelligence to estimate body composition in patients with obesity. The results show that this new method has high accuracy in estimating body composition in obese patients.

Summary: The usage of bio-impedance non-invasive measurement techniques is rapidly increasing in the agriculture industry. This paper proposes two new fractional-order bio-impedance plant stem models and compares them with three commonly used models. Experimental results show that the proposed models have the best fit with the measured data.

Summary: This study aims to evaluate body composition and its relationship with hormonal control in acromegaly, comparing the effectiveness of Bioelectrical impedance analysis (BIA) with dual X-ray absorptiometry (DXA), which is commonly used in current studies. The results show that there were no significant differences in body composition between patients with controlled and active disease. In patients with adequate hormonal control, there was preservation of muscle mass and a lower prevalence of metabolic comorbidities, such as type 2 diabetes (T2D) and high blood pressure (HBP).

Summary: The study aimed to evaluate the correlation between simple 2D measurements in axial slices of head and neck CT scans and established measurements of body composition in abdominal CT scans. The results showed that body composition information can be obtained with comparable reliability from head and neck CT using simple biplanar measurements as from abdominal CT.

Summary: Protein intake as a percentage of total energy intake is associated with bone mineral density and fracture risk in older adults. Higher protein intake is linked to higher BMD at the hip and lumbar spine, as well as a lower risk of vertebral fractures over 5 years.

Summary: This study aimed to assess whether delayed gastric emptying and impaired glucose absorption persist post-ICU discharge. The findings suggest that these factors recover rapidly after ICU discharge, but further research in a larger population is needed.

Summary: The study found that ARDS patients with imaging findings suggestive of non-focal morphology show the best re-aeration after receiving RMs, but the results are inconclusive in patients without ARDS.

Summary: This study found that preoperative diaphragm dysfunction is associated with prolonged mechanical ventilation after lung transplantation. In addition, the preoperative diaphragm dysfunction group showed more inhomogeneous ventilation, lower total lung volume, and lower FVC at 1 month and 3 months after transplantation.

Summary: The study compared different methods for estimating body volume and relative adiposity, finding that the 2D image analysis program provided an accurate and non-invasive estimate of body volume, and performed well in measuring relative adiposity within a 3-compartment model.

Summary: This study proposes a novel approach based on impedance myography to analyze muscle contractions, using the PhaseX Effect as a reliable and low signal processing marker. The method shows promising results in detecting muscle activity, which could be beneficial for applications such as prostheses control. The combination of a reliable marker and simple signal analysis has the potential to become a new method for prostheses control.

Summary: This article discusses an innovative and specific strategy for body composition assessment in athletes by applying BIVA, which is currently used in clinical practice, to sports. BIA is a simple, fast, inexpensive, noninvasive, accurate, and reproducible method for estimating BC, while BIVA provides a qualitative assessment of BCM and hydration status without the need for biological assumptions.
