Individuals with prior cancer diagnosis are more likely to have low muscle mass (LMM) than their cancer-free counterparts. Understanding the effects of LMM on the prognosis of cancer survivors can be clinically important. The aim of this study was to investigate whether risks for all-cause and cardiovascular disease (CVD)-specific mortality differ by status of LMM in cancer survivors and a matched cohort without cancer history. ⋯ Cancer survivors with LMM have an increased risk for all-cause and CVD-specific mortality. This increase appears to be larger than that in counterparts without cancer history.

Home parenteral nutrition (HPN) is the standard treatment for patients with chronic intestinal failure (CIF). Mortality and weaning rates of these patients differ widely among cohorts; however, these outcomes were often considered independent-rather than competing-events, leading to an upward bias of the retrieved estimates. ⋯ Surgical procedures strongly affected mortality and weaning risk in CIF patients.

Adipose tissue distribution and radiodensity are associated with prognosis in many types of cancer. However, the roles of adipose tissue distribution and radiodensity in patients with metastatic colorectal cancer (mCRC) remain unclear. The aim of this study was to assess the prognostic effect of adiposity and adipose tissue radiodensities in patients with mCRC. ⋯ A higher SAT index in patients with mCRC was associated with a favorable overall survival outcome, whereas higher SAT and VAT radiodensities were associated with an increased risk for death, supporting that early nutritional intervention may improve mCRC prognosis.

Systemic sclerosis (SSc) is a rare autoimmune disease characterized by microvascular damage and fibrosis of the skin and internal organs. Among SSc complications, changes in nutritional status have a negative effect on quality of life and predispose patients to malnutrition. The aim of this exploratory pilot study was to examine whether bioelectrical impedance analysis-derived phase angle (PhA) is a parameter of nutritional status and a marker of mortality in patients with SSc. ⋯ The data obtained suggest that lower PhA values in patients with SSc are associated with an increased malnutrition risk with MUST, malnutrition with GLIM, and increased mortality. Additional studies are necessary to confirm these preliminary results.

Zinc and copper are trace elements, but their reference values during the neonatal and infant periods are not clear. We aimed to determine the trend of serum zinc levels in infants admitted to the neonatal intensive care unit and compare serum zinc and serum copper levels at admission between small-for-gestational-age (SGA) and non-SGA infants. ⋯ All of the infants admitted to the neonatal intensive care unit at ≤34 wk of gestation were zinc deficient by 2 mo of age, suggesting the need for enteral zinc administration. Serum copper was higher in SGA infants than in non-SGA infants on admission, but further studies are needed to determine whether excess copper affects development.
