Increased homocysteine concentration and oxidative stress and decreased antioxidant capacities are thought to affect carcinogenesis. However, the associations of homocysteine, cysteine, pyridoxal 5'-phosphate (PLP) and folate with oxidative stress and antioxidant capacities in patients with colorectal cancer are unclear. The purpose of this study was to determine the associations of homocysteine, cysteine, PLP and folate with oxidative stress indicators and antioxidant capacities, and to further analyze their relationships with respect to risk for colorectal cancer. ⋯ Increased homocysteine was strongly associated with the risk of colorectal cancer independently of oxidative stress indicators and antioxidant capacities. However, cysteine, PLP and folate were not found to be related to oxidative stress, antioxidant capacities and the risk of colorectal cancer.

Fish oil-based emulsion is increasingly used in pediatric patients receiving Parenteral Nutrition (PN). However, its unique use in children on long-term PN is nutritionally debatable as some patients are better off with a mixture of long-chain (LCT) or long-chain + medium-chain (LCT + MCT) triglycerides along with Fish Oil (FO). Lipid emulsions are safely infused when particle diameter ranges between 0.4 and 1.0 micron (like chylomicra), according to European guidelines. ⋯ In particular, admixtures compounded with olive oil LCT + FO emulsion or FO emulsion alone showed lower particle diameters compared to admixture with olive/soybean LCT alone, probably due to a different steric encumbrance of oleic acid and omega-3 fatty acid. In the PN admixtures tested, containing FO-emulsion alone or in combination with olive LCT or LCT + MCT, the fat emulsion appears to be stable and safe for infusion when calcium concentration is maintained below 4.5 mmol/L. If calcium level exceeds 4.5 mmol/L, as often required in premature patients, it is advisable to infuse FO emulsion alone through a second intravenous line.

Observational Study
Energy and protein intakes of hospitalised patients with acute respiratory failure receiving non-invasive ventilation.
Nutritional intake of patients in acute respiratory failure receiving non-invasive ventilation has not previously been described, and no protocols have been developed to guide practice to optimise nutritional status. We aimed to measure energy and protein intakes of patients in acute respiratory failure requiring non-invasive ventilation receiving standard hospital nutritional care. ⋯ Patients with acute respiratory failure requiring non-invasive ventilation often had inadequate oral intake, particularly with increasing time on non-invasive ventilation, and earlier during their hospital admission. Development of protocols to optimise nutritional intake for these patients may improve outcomes and reduce regular readmission rates.

Pragmatic Clinical Trial
Multidisciplinary, multi-modal nutritional care in acute hip fracture inpatients - results of a pragmatic intervention.
Malnutrition is highly prevalent and resistant to intervention following hip fracture. This study investigated the impact of individualised versus multidisciplinary nutritional care on nutrition intake and outcomes in patients admitted to a metropolitan hospital acute hip fracture unit. ⋯ Multidisciplinary nutritional care improves nutrition intake and outcomes in acute hip fracture inpatients. Similar pragmatic study designs should be considered in other elderly inpatient populations perceived resistant to nutritional intervention.
