Not shortly after Roger Maris record was broken, another baseball player, Jason Giambi and various other athletes were either suspected of, or proven to have, taken anabolic steroids. Again, Congress convened a hearing, and just as they did the first time in 1990, they did not determine that steroids were a danger, but rather that the danger was more in protecting professional sports organizations. The updated statute has been updated to proscribe pro-hormones also The definition of an anabolic steroid as defined currently in the United States under (41)(A) is that "anabolic steroid" means any drug or hormonal substance, chemically and pharmacologically related to testosterone (other than estrogens , progestins, corticosteroids, and dehydroepiandrosterone (7).

Malnutrition associated with advanced lung disease has been termed the "pulmonary cachexia syndrome" and is characterized by loss of fat-free body mass [ 3 ]. The pulmonary cachexia syndrome is associated with an accelerated decline in functional status and can affect patients with any type of advanced lung disease, although it is best studied and described in association with chronic obstructive pulmonary disease (COPD) [ 3,4 ]. The incidence of undernutrition in patients with COPD depends on disease severity and the methods used to define nutritional status [ 5 ]. When cachexia is defined as less than 90 percent of ideal body weight, 20 to 50 percent of patients with COPD are underweight [ 6 ]. In the Intermittent Positive-Pressure Breathing (IPPB) Trial, 24 percent of the patients were underweight [ 7 ]. In the same study, among patients with an FEV 1 of less than 35 percent predicted, 50 percent were undernourished. Thus, the severity of airway obstruction correlates with the risk of undernutrition. Skeletal muscle wasting and dysfunction in advanced lung disease may be under recognized clinically, especially in overweight or obese patients, but may still signal a higher risk for morbidity and mortality.

The effect of the anabolic steroid oxandrolone on the healing rate of a standardized full thickness linear wound on the back of the rat was studied. Oxandrolone was given orally by gavage in peanut oil at a dose of mg/kg/day. A placebo powder in peanut oil was given at the same dose to a control group. Parameters monitored were time to complete wound closure, wound hydroxyproline content and tensile strength, as well as histology. We found that wounds closed completely in 12 ± 3 days with oxandrolone, compared to 18 ± 3 days for a placebo, a statistically significant difference. The rate of body weight gain was identical in both groups. Hydroxyproline content of the healed incision site was 23 ± 4 mg/g tissue vs. 17 ± 3 mg/g tissue, while the tensile strength increased to 185 ± 13 g/mm 2 vs. 102 ± 18 g/mm 2 in the oxandrolone and placebo groups, respectively. Both parameters were significantly increased with the anabolic steroid. Histologic examination showed a wound that contained more mature and densely packed collagen and was also hypercellular with oxandrolone treatment. We conclude that the anabolic steroid oxandrolone significantly enhanced wound healing unrelated to any generalized increase in protein mass as would be reflected in body weight.

Shelton and Rajfer (2012) noted that androgen deficiency in aging men is common, and the potential sequelae are numerous.  In addition to low libido, erectile dysfunction, decreased bone density, depressed mood, and decline in cognition, studies suggest strong correlations between low testosterone, obesity, and the metabolic syndrome.  Because causation and its directionality remain uncertain, the functional and cardiovascular risks associated with androgen deficiency have led to intense investigation of testosterone replacement therapy in older men.  Although promising, evidence for definitive benefit or detriment is not conclusive, and treatment of LOH is complicated.
