“…The device settings were standardized, and the measurements were taken with the patient lying in a supine position with legs relaxed and extended. QMLT was completed on bilateral lower limbs; measurements were obtained at 2 different landmarks, the midpoint and two‐thirds between the anterior superior iliac spine and the upper pole of the patella . A still image was taken with the transducer held perpendicular to the skin; the muscle thickness was quantified by using the onscreen calipers to measure the distance between the upper margin of the femoral bone and the lower boundary of the deep fascia of the rectus femoris muscle .…”

Duplicate measurements were taken at each landmark, and the mean of the 4 linear thicknesses was calculated for each leg separately . The first measurement was taken before randomization and then at discharge from ICU or day 15 (whichever came first).…”

“…Our group recently conducted the first study to validate the US measure of the thickness of the quadriceps and demonstrated that the measurement, in the hands of non‐ultrasonographers, has good reliability but only modestly correlates with the reference standard of the CT scan of third lumbar vertebrae estimates of lean muscle mass 69 . Chapple and colleagues 70 have furthered the utility of US of quadriceps thickness, showing that it strongly correlates with DEXA and subsequent 3‐month health‐related quality‐of‐life measures, the latter observation demonstrating an important relationship between measures of muscle mass and subsequent functional recovery in ICU survivors. Instead of a reference standard, repeated bedside US measurements using a protocol with high intrareliability and interreliability could potentially be used to demonstrate an individual patient's rate of loss/gain of muscle mass.…”

Protein Delivery in the Intensive Care Unit: Optimal or Suboptimal?

et al. 2017

Emerging evidence suggests that exogenous protein/amino acid supplementation has the potential to improve the recovery of critically ill patients. After a careful review of the published evidence, experts have concluded that critically ill patients should receive up to 2.0-2.5 g/kg/d of protein. Despite this, however, recent review of current International Nutrition Survey data suggests that protein in critically ill patients is underprescribed and grossly underdelivered. Furthermore, the survey suggests that most of protein administration comes from enteral nutrition (EN) despite the availability of products and protocols that enhance the delivery of protein/amino acids in the intensive care unit (ICU) setting. While future research clarifies the dose, timing, and composition for exogenous protein administration, as well as identification of patients who will benefit the most, ongoing process improvement initiatives should target a concerted effort to increase protein intake in the critically ill. This assertion follows from the notion that current patients are possibly being harmed while we wait for confirmatory evidence. Further research should also develop better tools to enable bedside practitioners to monitor optimal or adequate protein intake for individual patients. Finally, exploring the effect of combining adequate protein delivery with early mobility and/or resistance exercise in the ICU setting has the greatest potential for improving the functional outcomes of survivors of critical illness and warrants further study.

On behalf of the American Society for Parenteral and Enteral Nutrition (ASPEN), a systematic review was conducted to evaluate the best available evidence regarding the validity of relevant body composition methods (eg, dual energy X-ray absorptiometry [DXA], ultrasound [US], and bioelectrical impedance analysis [BIA]) in clinical populations. The guidelines targeted adults >18 years of age with a potentially inflammatory condition or pathological end point associated with a specific disease or clinical condition. In total, 7375 studies were retrieved, and 15 DXA, 7 US, and 23 BIA studies provided applicable data. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses was used to assess the diagnostic accuracy of the test method against a "gold standard" reference. The Grading of Recommendations, Assessment, Development and Evaluation criteria were used to separate the evaluation of the body of evidence from the recommendations. Based on a limited number of studies and expert opinion, DXA is recommended for the assessment of fat mass in patients with a variety of disease states; however, the validity of DXA for lean mass assessment in any clinical population remains unknown. No recommendations can be made at this time to support the use of US or BIA in the clinical setting, as data to support its validity in any specific patient population are limited in scope or by the proprietary nature of manufacture-specific BIA regression models to procure body composition data, respectively. Directions for future research are provided. These clinical guidelines were approved by the ASPEN Board of Directors. (JPEN J Parenter Enteral Nutr. 2020;44:12-43)
