“…Одним из первых и наиболее изученных параметров, используемых при ультразвуковой оценке ожирения, является интраабдоминальная толщина жировой ткани (Intra-abdominal fat thickness, IAFT), оцениваемая с помощью конвексного датчика (3,5-5 МГц). Однако нет единого мнения о том, какие анатомические параметры следует рассматривать в качестве эталона для УЗИ [10,13,14]. Большинство исследователей измеряют IAFT от задней стенки прямой мышцы живота (т.е.…”

Obesity as a risk factor for cardiovascular disease: focus on ultrasound

For many decades, obesity has been one of the main risk factors for cardiovascular disease. Despite medical advances, the obesity increases contribution to morbidity and mortality from cardiovascular diseases. Numerous anthropometric criteria for obesity are well-studied, simple and inexpensive tools for diagnosing overweight in the population. However, their accuracy is comparatively low. In particular, it is impossible to determine body composition based on these criteria, which is a key point in cardiovascular risk stratification. Despite the relatively short period of ultrasound practice for obesity diagnosis, convincing evidence has already been obtained of their high accuracy and effectiveness in predicting the risk of cardiovascular disease. Given the continuous improvement of ultrasound equipment, the studied criteria should be implemented in routine clinical and research practice. This literature review describes the central parameters used in the ultrasound diagnosis of obesity, their contribution to both conventional risk factors and cardiovascular diseases itself.

“…Although several methods can be used to accurately assess muscle quantity and quality such as computed tomography (CT), magnetic resonance imaging (MRI), and dual x-ray absorptiometry, these techniques require expensive equipment and are not portable, limiting their utility. Ultrasonography is a portable and relatively low-cost method of assessing muscle size [ 2 ], making it a potentially useful tool for evaluating sarcopenia for clinical or research purposes [ 3 , 4 ]. Beyond this, ultrasonography records a measure of muscle quality in the form of echogenicity or echo intensity [ 5 , 6 , 7 ], making ultrasound a potentially more powerful tool than bioelectrical impedance for assessing sarcopenia or signs of pre-sarcopenia in middle age.…”

Ultrasonography advantageously measures skeletal muscle size and quality, but some muscles may be too large to capture with standardized brightness mode (B-mode) imaging. Panoramic ultrasonography can capture more complete images and may more accurately measure muscle size. We investigated measurements made using panoramic compared to B-mode ultrasonography images of the rectus femoris with muscular performance. Concurrently, protein intake plays an important role in preventing sarcopenia; therefore, we also sought to investigate the association between animal-based protein intake (ABPI) and muscular performance. Ninety-one middle-aged adults were recruited. Muscle cross-sectional area (CSA) and thickness were obtained using B-mode and panoramic ultrasound and analyzed with Image J software. Muscular performance was assessed using isokinetic dynamometry, a 30-s chair test, and handgrip strength. Three-day food diaries estimated dietary intakes. Linear regression models determined relationships between measures from ultrasonography and muscular performance. Mixed linear models were used to evaluate the association between ABPI and muscular performance. Muscle CSA from panoramic ultrasonography and ABPI were positively associated with lower-body strength (β ± S.E.; CSA, 42.622 ± 20.024, p = 0.005; ABPI, 65.874 ± 19.855, p = 0.001), lower-body endurance (β ± S.E.; CSA, 595 ± 200.221, p = 0.001; ABPI, 549.944 ± 232.478, p = 0.020), and handgrip strength (β ± S.E.; CSA, 6.966 ± 3.328, p = 0.004; ABPI, 0.349 ± 0.171, p = 0.045). Panoramic ultrasound shows promise as a method for assessing sarcopenia. ABPI is related to better muscular performance.

Introduction:Excess body fat is linked to higher risks for metabolic syndrome, type 2 diabetes mellitus (T2DM), and cardiovascular disease (CV), among other health conditions. However, it is not only the level but also the distribution of body fat that contributes to increased disease risks. For example, an increased level of abdominal fat, or visceral adipose tissue (VAT), is associated with a higher risk of nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH).Methods: A review of the most relevant primary and secondary sources on body composition from the last 25 years was conducted. Relevant articles were identified using PUBMED and Google Scholar. Narrative synthesis was performed as statistical pooling was not possible due to the heterogeneous nature of the studies. Results:The body mass index (BMI) is commonly used as a proxy measure of body fatness. However, BMI does not reflect the level and distribution of body fat. Other anthropometric methods such as waist circumference measurement and waist-hip ratio, as well as methodologies like hydro densitometry, bioelectrical impedance, and isotope dilution are also limited in their ability to determine body fat distribution.Imaging techniques to define body composition have greatly improved performance over traditional approaches. Ultrasound (US), computed tomography (CT), dualenergy X-ray absorptiometry (DXA), magnetic resonance imaging (MRI), are now commonly used in clinical research. Of these, MRI can provide the most accurate and high-resolution measure of body composition. In addition, MRI techniques are considered the best for the determination of fat at the organ level. On the other hand, imaging modalities require specialized, often expensive equipment and expert operation.Conclusions: Anthropometric methods are suitable for rapid, high-volume screening of subjects but do not provide information on body fat distribution. Imaging techniques are more accurate but are expensive and do not lend themselves for high throughput. Therefore, successful trial strategies require a tiered approach in which subjects are first screened using anthropometric methods followed by more sophisticated modalities during the execution of the trial.
