OBJECTIVE: To measure resting energy expenditure (REE) in a group of people with postacute paraplegia, quantify the impact of asymptomatic bacteriuria and pressure sore(s) on patients' metabolic rate, and estimate the adequacy of patients' nutritional intakes to preserve patients' protein levels. MATERIAL AND METHODS: Ten males with post-acute paraplegia aged 42.1+/-18.7 years. We evaluated: height, body mass index (BMI), resting energy expenditure (REE), total daily calorie requirement (E), 24-h urine creatinine excretion (Cru), creatinine index (CI), and nitrogen balance (NB). RESULTS: Subjects with paraplegia showed high erythrocyte sedimentation rates. As a group, they had normal resting calorie consumption when REE was normalized for unit of urine creatinine (REE/Cru), it was higher in patients than in controls. Six of the 10 patients had a low calorie intake: of these only three had a negative nitrogen balance. CONCLUSION: In conclusion, the resting energy expenditure of the subjects with significant bacteriuria and pressure sore(s) of 23.7 kcal/kg/day suggests that a large portion of patients may have an inadequate calorie protein intake to preserve their nutritional status. The clinical significance of this study is that 28.5 kcal/kg/day may be the lower calorie threshold to meet the metabolic demands of people with apyretic paraplegia with bacteriuria and pressure sore(s).

Background: This retrospective study had two main aims: (1) to document possible correlations between plasma Amino Acids (AAs) and circulating Albumin (Alb) and Haemoglobin (Hb); and (2) to identify which AAs were predictors of Alb and Hb., Methods: The study considered 125 stroke subjects (ST) (61.6% males; 65.6 +/- 14.9 years) who met the eligibility criteria (absence of co morbidities associated with altered plasma AAs and presence of plasma AAs determined after overnight fasting). Fifteen matched healthy subjects with measured plasma AAs served as controls., Results: The best correlations of Alb were with tryptophan (Trp) and histidine (His) (r = + 0.53; p < 0.0001), and those of Hb were with histidine (r = +0.47) and Essential AAs (r = +0.47) (both p<0.0001). In multivariate analysis, Trp (p< 0.0001) and His (p = 0.01) were shown to be the best positive predictors of Alb, whereas glutamine (p = 0.006) was the best positive predictor of Hb., Conclusions: The study shows that the majority of plasma AAs were positively correlated with Alb and Hb. The best predictors of circulating Alb and Hb were the levels of tryptophan and glutamine, respectively., Competing Interests: The author Roberto Aquilani is a scientific consultant at Professional Dietetics (Milano, Italy).

Diagnostic accuracy and reliable estimation of clinical evolution are challenging issues in the management of patients with disorders of consciousness (DoC). Longitudinal systematic investigations conducted in large cohorts of patients with DoC could make it possible to identify reliable diagnostic and prognostic markers. On the basis of this consideration, we devised a multicentre prospective registry for patients with DoC admitted to ten intensive rehabilitation units. The registry collects homogeneous and detailed data on patients' demographic and clinical features, neurophysiological and neuroimaging findings, and medical and surgical complications. Here we present the rationale and the design of the registry and the preliminary results obtained in 53 patients with DoC (vegetative state or minimally conscious state) enrolled during the first seven months of the study. Data at 6-month post-injury follow-up were available for 46 of them. This registry could be an important tool for collecting high-quality data through the application of rigorous methods, and it could be used in the routine management of patients with DoC admitted to rehabilitation settings.
