Effect of perioperative blood transfusion on recurrence and survival in 232 primary high-grade extremity sarcoma patients.

Background: Allogeneic blood transfusion (BT) has been implicated as an unfavorable factor influencing cancer recurrence and overall survival.

Methods: To investigate this, 232 consecutive localized, high-grade extremity soft tissue sarcoma (STS) patients admitted between January 1, 1983, and December 31, 1989, were analyzed from our prospective database by univariable and Cox multivariable statistical methods.

Results: Twenty-eight patients developed a local recurrence (LR).

The effect of systemic hyperinsulinemia with concomitant amino acid infusion on skeletal muscle protein turnover in the human forearm.

In vitro, insulin has been shown to increase skeletal muscle (SM) protein synthesis and decrease SM protein breakdown. Whether these same effects are found in vivo in man is less clear. The study of the effect of hyperinsulinemia (INS) on SM protein turnover (SMPT) is complicated by hypoaminoacidemia, which can obviate the true effect of insulin on SMPT.

Abdominal aortic pseudoaneurysm after blunt trauma.

A 4-year-old male child was admitted with a large 12 x 15 cm suprarenal abdominal aortic pseudoaneurysm 7 months after an episode of blunt abdominal trauma. Aneurysmorrhaphy was performed through a left thoracoabdominal approach with Dacron patch aortoplasty. This report summarizes this case and reviews the literature on abdominal aortic pseudoaneurysms after blunt abdominal trauma.

Growth hormone and insulin reverse net whole body and skeletal muscle protein catabolism in cancer patients.

The authors examined the effect of recombinant-human growth hormone (r-hGH) and insulin (INS) administration on protein kinetics in cancer patients. Twenty-eight cancer patients either received r-hGH for 3 days (GH group, n = 12, weight loss = 6 +/- 2%) or were not treated (control [CTL] group, n = 16, weight loss = 11 +/- 2%) before metabolic study. Recombinant-human growth hormone dose was 0.

Growth hormone and insulin combine to improve whole-body and skeletal muscle protein kinetics.

Background: A cooperative effect of exogenous insulin and recombinant human growth hormone (r-hGH) with respect to whole-body and skeletal muscle protein metabolism has not been demonstrated previously. This study examined the effect of r-hGH and insulin administration during euglycemic clamping and concurrent amino acid supplementation.

Methods: Twenty-three normal volunteers in the postabsorptive state were either treated with r-hGH for 3 consecutive days before a metabolic study (GH group; n = 10) or not treated (CTRL group; n = 13).

The effect of insulin on glucose and protein metabolism in the forearm of cancer patients.

This study was designed to study the effect of systemic hyperinsulinaemia (INS) on glucose and protein metabolism in cancer patients. Sixteen cancer patients (8 > 10% weight loss (WL); 8 < 10% weight loss (NWL)) were compared with 12 healthy controls. Glucose uptake (GU) and phenylalanine (PHE) exchange kinetics were measured across the forearm in the postabsorptive state (PA) and in response to INS (71 +/- 5 microU ml-1).

Effect of systemic hyperinsulinemia in cancer patients.

Data defining the isolated effect of insulin on whole body protein and glucose metabolism in cancer patients are limited. Ten normal volunteers (controls), age 55 +/- 3 years (mean +/- SEM); 8 cancer patients, age 61 +/- 3 years, weight loss 2 +/- 1% (CANWL); and 8 cancer patients, age 55 +/- 2 years, weight loss 18 +/- 2% (CAWL), were studied in the post-absorptive state. Whole body leucine kinetics were determined during a baseline and then a study period during which insulin was infused at 1.

Effect of hyperinsulinemia on whole body and skeletal muscle leucine carbon kinetics in humans.

Data documenting the isolated effect of systemic hyperinsulinemia on whole body and skeletal muscle leucine carbon kinetics in humans are limited. Using steady-state [14C]leucine kinetics, 10 normal volunteers were studied in the baseline postabsorptive state and then under euglycemic, hyperinsulinemic (71 +/- 5 microU/ml), and euleucinemic conditions. Systemic hyperinsulinemia resulted in a significant decrease in whole body and forearm leucine rate of appearance (Ra) by 17 and 37%, respectively, (P less than 0.

A consumer perspective.

The consumer's perspective of over-the-counter medication should be one of the most important determinants of strategy for individuals and companies manufacturing and distributing such products. The consumers, buyers, and users have been telling industry for a long time that they are concerned with safety, cost, effectiveness, and availability of choice. The wise producers have begun to heed the signs and the public is responding.
