“…This idea has support from the fact that the mean BMI values were slightly higher for cases (28.4) and for controls (28.4) in the prior US study relative to the study presented here, and this was despite the younger mean ages of the prior study. Although no associations were observed in the present study when stratified by BMI or waist circumference, waist-tohip ratio is the highest anthropometric correlate of visceral adipose tissue/subcutaneous adipose tissue ratio in men (Bazzocchi et al 2014) and both of these fat depots have been implicated in risk of Barrett's esophagus, with waist circumference positively associated (Kubo et al 2013) and hip circumference inversely associated (Kendall et al 2016). Similar effects have been noted for esophageal adenocarcinoma (Steffen et al 2015).…”

Sex steroid hormones in relation to Barrett's esophagus: an analysis of the FINBAR Study

et al. 2017

Previously we observed strong positive associations between circulating concentrations of free testosterone and free dihydrotestosterone (DHT) in relation to Barrett's esophagus in a US male military population. To replicate these findings, we conducted a second study of sex steroid hormones and Barrett's esophagus in the Factors Influencing the Barrett/Adenocarcinoma Relationship (FINBAR) Study based in Northern Ireland and Ireland. We used mass spectrometry to quantitate EDTA plasma concentrations of nine sex steroid hormones and ELISA to quantitate sex hormone binding globulin in 177 male Barrett's esophagus cases and 185 male general population controls within the FINBAR Study. Free testosterone, free DHT, and free estradiol were estimated using standard formulas. Multivariable logistic regression estimated odds ratios (OR) and 95% confidence intervals (95%CI) of associations between exposures and Barrett's esophagus. While plasma hormone and sex hormone binding globulin concentrations were not associated with all cases of Barrett's esophagus, we did observe positive associations with estrogens in younger men (e.g., estrone + estradiol ORcontinuous per ½ IQR=2.92, 95%CI:1.08, 7.89), and free androgens in men with higher waist-to-hip ratios (e.g., free testosterone ORcontinuous per ½ IQR=2.71, 95%CI:1.06, 6.92). Stratification by body mass index, antireflux medications, and geographic location did not materially affect the results. This study found evidence for associations between circulating sex steroid hormones and Barrett's esophagus in younger men and men with higher waist-to-hip ratios. Further studies are necessary to elucidate whether sex steroid hormones are consistently associated with esophageal adenocarcinogenesis.

“…This is particularly true for the Endocrine newer DXA devices, as the one we used. Such a machine provides enhanced resolution, improved image quality, and better algorithms for body composition assessment compared to the earlier densitometers, thus allowing a very accurate estimation of fat distribution, muscle (sarcopenia), and bone mass [6,[15][16][17]. However, as DXA devices are expensive and not available in all settings, their use in daily practice is limited.…”

Estimate of body composition by Hume’s equation: validation with DXA

et al. 2014

We investigated how the Hume's equation, using the antipyrine space, could perform in estimating fat mass (FM) and lean body mass (LBM). In 100 (40 male ad 60 female) subjects, we estimated FM and LBM by the equation and compared these values with those measured by a last generation DXA device. The correlation coefficients between measured and estimated FM were r = 0.940 (p \ 0.0001) and between measured and estimated LBM were r = 0.913 (p \ 0.0001). The BlandAltman plots demonstrated a fair agreement between estimated and measured FM and LBM, though the equation underestimated FM and overestimated LBM in respect to DXA. The mean difference for FM was 1.40 kg (limits of agreement of -6.54 and 8.37 kg). For LBM, the mean difference in respect to DXA was 1.36 kg (limits of agreement -8.26 and 6.52 kg). The root mean square error was 3.61 kg for FM and 3.56 kg for LBM. Our results show that in clinically stable subjects the Hume's equation could reliably assess body composition, and the estimated FM and LBM approached those measured by a modern DXA device.

“…The MT of the forearm flexors (i.e., biceps brachii and brachialis) was accepted as the distance (cm) from the adipose tissue-muscle interface to the muscle-bone interface (Radaelli et al 2013). The FT was accepted as the distance (cm) from the surface of the skin to the adipose tissue-muscle interface (Bazzocchi et al 2014). Both MT and FT were determined using the straight-line function in the ImageJ software (Fig.…”
