[The effect of nutrition support and recombinant growth hormone on body composition and muscle function in postoperative patients].

What Was Tested

The paper reports a study of Exogenous HGH, sermorelin & older GHRPs (why they're passed over), published as a randomized controlled trial.

To determine the effects of nutritional support and recombinant human growth hormone (GH) on body composition and muscle function, the researchers performed a randomized double-blind trial in 18 patients after elective gastrectomy or colectomy.

Why It Was Studied

Same amount of calories and amino acids were administered.

Who Took Part

The abstract describes 18 patients taking part.

By PubMed's age tags, the people studied were adults, middle-aged adults and older adults, men only.

How the Study Was Run

In design terms this was a randomized, double-blind and placebo-controlled study.

Because people in this Exogenous HGH, sermorelin & older GHRPs (why they're passed over) study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Blinding on both sides kept the patients and researchers unaware of who received Exogenous HGH, sermorelin & older GHRPs (why they're passed over).

The comparison arm used a placebo, so changes seen with Exogenous HGH, sermorelin & older GHRPs (why they're passed over) could be set against what happens without it.

What Was Measured

Topics PubMed links to this paper include Body Composition, Colectomy, Gastrectomy, Growth Hormone, Hand Strength, Muscles and Parenteral Nutrition.

What This Means in Plain Language

The paper is a randomized, double-blind and placebo-controlled study of Exogenous HGH, sermorelin & older GHRPs (why they're passed over) in 18 patients.

With fewer than 40 people, it is a small study, so it is better read as an early signal for further research than as a settled answer.

The publication is from 1994 (Zhongguo yi xue ke xue yuan xue bao. Acta Academiae Medicinae Sinicae), a journal based in China.
