187 Background: Cancer anorexia-cachexia syndrome (CACS) in patients is associated with decreases in lean body mass and body weight. Self-reported lack of appetite may be an important indicator for early identification of CACS. The current analyses examined the relationship of perceived lack of appetite to patient characteristics and overall symptom burden in a large mixed cancer sample referred to a palliative care clinic. Methods: We conducted a retrospective review of patients newly referred to an outpatient palliative care clinic over a two-year period. Data on demographic and clinical characteristics and patient-reported symptom scores on the Edmonton Symptom Assessment Scale (ESAS) were abstracted. Pearson’s correlations and ANOVAs were used to assess relationships between variables. Multiple regression analysis was used to evaluate the relative contribution of variables that were significantly correlated with lack of appetite at the univariate level. Results: Data on 544 patients ( M=53.7 years) showed that older age (r=12, p<.01), not being married or in a marriage-like relationship (r=.09, p=.04), having insurance other than managed care insurance (r=.10, p=.02), lower body mass index (BMI; r=.11, p<.01), marijuana use (r=.18, p<.0001), and overall symptom burden (ESAS total score r=.52, p < .0001) were associated with worse lack of appetite ( M=3.5, SD=3.1). Patients who were underweight (BMI <18.5, 46.7%) reported significantly worse lack of appetite than patients who were normal weight, overweight, or obese ( M=3.9, SD=3.2, p<.01). The final hierarchical regression model accounted for 34% of the variance in lack of appetite, with age, marital status, BMI, marijuana use, and total symptom burden remaining significant independent correlates (p’ s <.01). Conclusions: Contrary to expectations, relatively few clinical correlates were associated with self-reported lack of appetite. Future research should explore inter-individual genetic factors to explain alterations in lean body mass and body weight that may contribute to poor appetite in patients. Such factors may be important indicators for early identification of CACS.

Abstract Context Older adults have the greatest burden of diabetes; however, the contribution of age-related muscle loss to its development remains unclear. Objective We assessed the relationship of lean body mass with aging to incident diabetes in community-dwelling adults. Design and Setting We studied participants in the Baltimore Longitudinal Study of Aging with median follow-up of 7 years (range 1-16). Cox proportional hazard models with age as the time scale were used. Time-dependent lean body mass measures were updated at each follow-up visit available. Participants Participants included 871 men and 984 women without diabetes who had  ≥ 1 assessment of body composition using dual x-ray absorptiometry. Main Outcomes Incident diabetes, defined as self-reported history and use of glucose-lowering medications; or fasting plasma glucose ≥ 126 mg/dL and 2-hour oral glucose tolerance test glucose ≥ 200 mg/dL either at the same visit or 2 consecutive visits. Results The baseline mean [standard deviation] age was 58.9  [17.3] years. Men and women with a higher percentage of total lean body mass had lower fasting and 2-hour glucose levels, and less prediabetes (all P &lt; 0.01). Among men, comparing highest versus lowest quartiles, percentage of total lean body mass (hazard ratio [HR],  0.46; 95% confidence interval, 0.22-0.97), percentage leg lean mass (HR, 0.38; 0.15-0.96), and lean-to-fat mass ratio (HR, 0.39; 0.17-0.89) were inversely associated with incident diabetes after accounting for race and attenuated after adjustment for height and weight. Conversely, absolute total lean body mass was positively associated with incident diabetes among women, with similar trends in men. No associations were observed with muscle strength or quality. Conclusions Relatively lower lean body mass with aging is associated with incident diabetes in men and partially related to anthropometrics, but not so in women.

In vivo neutron activation has provided investigators with a powerful tool for research on body composition. Total-body nitrogen (TBN), total-body potassium (TBK), and total-body water (TBW) were measured in 133 normal subjects. TBN, measured by neutron activation, is a measure of total-body protein, an index of body cell mass. TBK, also measured by a nuclear reaction, is an index of body cell mass as well as lean body mass. The mass and protein content of two compartments, muscle and nonmuscle lean tissue, were determined from the combined TBN-TBK data by compartmental analysis. In this study, nitrogen was separated into the actively metabolizing body cell mass component and the slowly metabolizing structural component. The TBK, which is 95% intracellular, was found to be more closely related to the actively metabolizing nitrogen than to TBN. The relationship of body cell mass, a concept originally proposed by Moore, to lean body mass, is shown through the relationship of TBN and TBK. The clinical significance of this study, is that TBK is the more sensitive and reliable indicator of changes in body cell mass. Maximum information on body composition, however, is obtained by the measurement of both TBK and TBN.
