“…22 Excess hydration can mislead body composition results of air displacement plethysmography 23 by temporarily increasing LBM. 24 For these reasons, body composition was compared with pre-admission (median − 9.5 days, range − 21 to 9 days of transplantation) when nutritional status and hydration were stable.…”

Adverse changes in nutrition-related outcomes including quality of life (QoL) occur after PBSC transplantation. This randomised controlled trial aims to evaluate the impact of nutrition and exercise counselling provided at hospital discharge on nutritional status, body composition and QoL post transplantation. Usual care (UC) (n = 19) received no intervention after discharge; extended care (EC) (n = 18) received fortnightly telephone counselling from a dietitian and exercise physiologist up to 100 days post transplantation. Nutritional status (patient-generated subjective global assessment, and diet history), QoL (EORTC QLQ-C30 version 3) and body composition (air displacement plethysmography) were assessed at pre-admission, discharge and 100 days post transplantation. Intervention groups were compared using two-sample t-tests of changes in the outcomes; results were adjusted using analysis of covariance. EC exhibited clinically important but not statistically significant increases in protein intake (14.7 g; confidence interval (CI) 95% − 6.5, 35.9, P = 0.165), cognitive functioning (7.2; CI 95% − 7.9, 22.2, P = 0.337) and social functioning (16.5; CI 95% − 7.3, 40.3, P = 0.165) compared with UC. Relative to pre-admission, EC experienced less weight loss than UC (−3.3 kg; CI 95% − 6.7, 0.2, P = 0.062). Physical activity was not significantly different between the groups. Ongoing nutrition and exercise counselling may prevent further weight loss and improve dietary intake and certain QoL components in autologous PBSC transplantation patients following hospitalisation.

“…Previous studies on the influence of insulin therapy on BC of patients with diabetes mellitus have been limited because the methods for analyzing BC (tritiated water, underwater weighing or four-compartment model) are difficult to use in clinical practice. Air displacement plethysmography is a new, safe, quick, and valid technique, providing accurate measurements of body density [6] and discriminating moderate changes in FM and FFM [7]. Although some uncertainties due to the hydration of FFM may influence any two-compartment model-based analysis [8], the simultaneous measurement of muscle strength (MS) by dynamometry can be used to confirm the results of FFM: a correlation between FFM and MS has been previously demonstrated [9–11] …”

Aims. To determine the progression of body weight (BW) and body composition (BC) in patients with type 2 diabetes mellitus (T2D) on insulin therapy and the consequences on muscle strength (MS) as a reflect of free fat mass increases. Research design and methods. We analysed BC using air displacement plethysmography and MS by hand grip dynamometry in 40 T2D before and after three (M3) and six months (M6) of insulin therapy. Results. at baseline HbA1c was 9.76 ±1.6% and BW was stable with fat mass (FM) 28 ± 10.7 kg; and fat free mass (FFM) 52.4 ± 11 kg; at M6, HbA1c improved to 7.56 ± 0.8%; insulin doses tended to increase. BW gain at M6 was + 3.2 ± 4.2 kg and with an increase of only 25% by M3; it was composed of FM, whereas FFM was unchanged. MS did not increase on insulin therapy. Conclusions. In T2D, BW gain was composed exclusively of FM with no improvement in MS.

“…Pouzdanost metode je velika [31] i pokazano je da ona detektuje promene u masnoj masi i u bezmasnoj masi [32]. Pletizmografska metoda je podložna istim greškama kao i hidrodenzitometrijska ako se koristi Sirijeva ili neka druga jednačina za preračunavanje procenta telesnih masti iz procenjene gustine tela.…”

Procena telesne kompozicije zauzima važno mesto u proceni zdravstvenih rizika u brojnim medicinskim granama, kao i u oblasti fiziologije sporta kao važna komponenta fiziološkog profila sportiste. Postoje brojni pristupi proceni telesne kompozicije, koji se mogu grubo podeliti na direktne i indirektne. Danas se u kliničkoj praksi koriste indirektni modeli, koji na relativno jednostavan i brz način mogu dati podatke o udelu pojedinih komponenti telesnog sastava. Najjednostavnija, i za širu populaciju najdostupnija metoda je antropometrijska, dok se kao metodom rastuće pouzdanosti označava metoda bioelektrične impedance. Hidrodenzitometrija, iako pouzdana, nije metod izbora u većim studijama zbog nekomformnosti samog postupka i zahtevnijih uslova po pitanju opreme. DXA metoda zbog svoje velike pouzdanosti ima potencijal primene kao zlatnog standarda za procenu komponenata telesnog sastava, a uključuje relativno malu dozu zračenja. CT i NMR su najsofisticiranije metode kojima se egzaktno može proceniti masna masa različitih regiona tela, visceralna masna masa kao i mišićna masa tela. Međutim zbog male dostupnosti i visoke cene nemaju primenu u široj populaciji, ali su veoma važne u raličitim kliničkih studijama. Možda najbolji pristup procene telesne kompozicije je kombinacijom više jednostavnih i dostupnih metoda čime se može povećati pouzdanost dobijenih podataka i adekvatnije proceniti zdravstveni rizici vezani za specifični telesni sastav.Ključne reči: telesna kompozicija, sportisti, antropometrija, indeks telesne mase. UVODTelesna struktura čoveka kao jedinstvo konstitutivnih elemenata ljudskog tela ima veliki značaj u različitim medicinskim disciplinama, kada se prate faktori rizika za nastanak i razvoj bolesti, ali i za razumevanje procesa rasta i razvoja ljudskog organizma [1]. Posebno mesto zauzima analiza telesne kompozicije u sportskim naukama jer je ona jedan od elemenata koji čine fiziološki profil spotiste, i ima značajnu ulogu u postizanju vrhunskih rezultata. Istorijski gledano, interes za telesnu kompoziciju narastao je sa potrebom da se proceni masna masa tela. U tom kontekstu, najviše pažnje u ovoj oblasti usmereno je na kvantitativnu procenu masne i mišićne mase tela.Martin i Drinkwater [2] su 1991 godine predložili tri pristupa proceni telesne kompozicije. Metodom prvog nivoa mere se direktno komponente telesne strukture, a baziran je na podacima dobijenim disekcijom kadavera gde se ukupna masna masa tela određuje ekstrakcijom svih lipida iz tela. Prvi podaci o telesnom sastavu dobijenom na ovaj način potiču iz rada nemačkih anatoma koji su objavili prve podatke o direktnoj analizi telesne kompozicije [3]. Do osamdesetih godina prošlog veka izvedeno je samo nekoliko studija sa relativno malim brojem kompletnih disekcija kadavera [4,5].Sve druge metode procene telesne kompozicije su zapravo indirektne metode, i mogu biti indirektne metode drugog ili trećeg nivoa (dvostruko indirektne). Procene stukture na drugom ili trećem nivou bazirane su na pretpostavkama i izvedenim jednačinama. Drugi nivo po...
