The Norwegian Directorate of Health recommends malnutrition screening tool (MST) for all adults.

BACKGROUND & AIMS: Malnutrition is underdiagnosed and undertreated in Norway. In a revision of a national guideline on malnutrition, the Norwegian Directorate of Health aimed for a harmonization and standardization of the malnutrition screening practice, including a recommendation of one malnutrition screening tool to be used among all adults in Norwegian health and care services. METHODS: A working group was appointed by the Norwegian Directorate of Health. Evidence-based practice, a pragmatic decision-making process based on a literature review, the Grading of Recommendations Assessment, Development and Evaluation (GRADE), and the DECIDE decision-making model was used as a guidance in order to convert evidence into recommendations. RESULTS: The criteria and properties of the four most frequently validated malnutrition screening tools were identified and ranked by the working group. The tools were prioritized in the following order: 1: Malnutrition Screening Tool (MST), 2: Malnutrition Universal Screening Tool (MUST), 3: Nutritional Risk Screening 2002 (NRS-2002), and 4: Mini-Nutritional Assessment short form (MNA). CONCLUSIONS: The Norwegian Directorate of Health recommends use of MST for screening for malnutrition among all adults (≥18 years), across all health care settings, and diagnoses or conditions in Norway.

Harmonization and standardization of malnutrition screening for all adults - A systematic review initiated by the Norwegian Directorate of Health.

BACKGROUND & AIMS: The Norwegian Directorate of Health has identified a need to harmonize and standardize the malnutrition screening practice in Norwegian hospitals and primary health care settings, in order to provide a seamless communication of malnutrition screening along the patient pathway. Our aim was to perform a systematic review of the validity and reliability of screening tools used to identify risk of malnutrition across health care settings, diagnoses or conditions and adult age groups, as a first step towards a national recommendation of one screening tool. METHODS: A systematic literature search for articles evaluating validity, agreement, and reliability of malnutrition screening tools, published up to August 2020, was conducted in: MEDLINE, Embase, APA PsycInfo, Cinahl, Cochrane Databases, Web of Science, Epistemonikos, SveMed+, and Norart. The systematic review was registered in PROSPERO (CRD42022300558). For critical appraisal of each included article, the Quality Criteria Checklist by The Academy of Nutrition and Dietetics was used. RESULTS: The review identified 105 articles that fulfilled the inclusion and exclusion criteria. The most frequently validated tools were Mini Nutritional Assessment short form (MNA), Malnutrition Universal Screening Tool (MUST), Malnutrition Screening Tool (MST), and Nutritional Risk Screening 2002 (NRS-2002). MNA, MST and NRS-2002 displayed overall moderate validity, and MUST low validity. All four tools displayed low agreement. MST and MUST were validated across health care settings and age groups. In general, data on reliability was limited. CONCLUSIONS: The screening tools MST and NRS-2002 displayed moderate validity for the identification of malnutrition in adults, of which MST is validated across health care settings. In addition, MNA has moderate validity for the identification of malnutrition in adults 65 years or older.

Postradiotherapy plasma lutein, alpha-carotene, and beta-carotene are positively associated with survival in patients with head and neck squamous cell carcinoma.

The aim of our study was to compare plasma carotenoids (i.e., biomarkers of fruits and vegetables intake) and tocopherols in 29 head and neck squamous cell carcinoma (HNSCC) patients with 51 healthy controls and to explore the possibility whether these plasma antioxidants could be related to outcome among patients. The patients' blood samples were taken at the end of radiotherapy. We observed that plasma lutein, zeaxanthin, alpha-carotene, beta-carotene, lycopene, and total carotenoids were significantly lower in HNSCC patients than controls. Among the patients, 18 died and 11 were still alive during median follow-up of 55 mo for survivors. We found a significant positive association between postradiotherapy plasma carotenoids (lutein, alpha-carotene, and beta-carotene) and progression-free survival in these patients. This study indicates that increasing postradiotherapy plasma carotenoid concentration may reduce risk of premature death or recurrence of tumor in HNSCC patients. Increasing plasma carotenoid concentration should be done by increasing intake of carotenoid-rich fruits and vegetables, as other studies have shown either no or negative effects due to use of carotenoid supplements.
