Impact of radiotherapy on body weight in head and neck cancer patients: A prospective study.

Background: Patients with head and neck cancer (HNC) undergoing radiotherapy or chemoradiotherapy often experience symptoms that affect their ability to eat. This study aimed to explore the impact of radiotherapy on body weight in HNC patients and compare the characteristics of patients receiving enteral tube feeding with those maintaining an oral diet.

Methods: In this prospective study, 52 patients with HNC were examined at diagnosis, at the start and end of radiotherapy, and six weeks after end of treatment.

Barriers and facilitators of improved nutritional support for patients newly diagnosed with cancer: a pre-implementation study.

Background: Disease-related malnutrition affects a significant number of patients with cancer and poses a major social problem worldwide. Despite both global and national guidelines to prevent and treat malnutrition, the prevalence is high, ranging from 20 to 70% in all patients with cancer. This study aimed to explore the current practice of nutritional support for patients with cancer at a large university hospital in Norway and to explore potential barriers and facilitators of the intervention in the Green Approach to Improved Nutritional support for patients with cancer (GAIN), prior to implementation in a clinical setting.

Attenuation of DNA base oxidation in post-surgery colorectal stage III patients at subsequent follow-ups.

DNA damage caused by oxidative reactions plays a crucial role in the pathogenesis of colorectal cancer (CRC). In a previous cross-sectional study, CRC patients diagnosed with regional disease (stage III) exhibited a higher level of DNA base oxidation in peripheral blood mononuclear cells (PBMCs) 2-9 months post-surgery compared to those with localized disease (stage I-II). To further explore this observation over time, the present study aimed to investigate DNA base oxidation in CRC patients with localized versus regional disease 6 and 12 months after the initial measurements.

Effect of a personalized intensive dietary intervention on base excision repair (BER) in colorectal cancer patients: Results from a randomized controlled trial.

DNA repair is essential to maintain genomic integrity and may affect colorectal cancer (CRC) patients' risk of secondary cancers, treatment efficiency, and susceptibility to various comorbidities. Bioactive compounds identified in plant foods have the potential to modulate DNA repair mechanisms, but there is limited evidence of how dietary factors may affect DNA repair activity in CRC patients in remission after surgery. The aim of this study was to investigate the effect of a 6-month personalized intensive dietary intervention on DNA repair activity in post-surgery CRC patients (stage I-III).

The choice of diagnostic modality influences the proportion of low muscle strength, low muscle mass, and sarcopenia in colorectal cancer patients.

Background And Aims: Low muscle strength, low muscle mass, and sarcopenia have a negative impact on health outcomes in colorectal cancer (CRC) patients. Different diagnostic modalities are used to identify these conditions but it is unknown how well the modalities agree. The aim of this study was to compare different diagnostic modalities by means of calculating the proportion of low muscle strength, low muscle mass, and sarcopenia in CRC patients, and to investigate the agreement for sarcopenia between the various modalities.

Malnutrition prevalence according to GLIM and its feasibility in geriatric patients: a prospective cross-sectional study.

Purpose: In 2019, the Global Leadership Initiative on Malnutrition (GLIM) suggested a 2-step diagnostic format for malnutrition including screening and diagnosis. Prospective validation and feasibility studies, using the complete set of the five GLIM criteria, are needed. The aims of this study were to determine the prevalence of malnutrition, and investigate how the prevalence varied with mode of screening.

Prevalence of malnutrition among older adults in a population-based study - the HUNT Study.

Background: Malnutrition is common in older adults and is associated with increased morbidity and mortality rates.

Aim: The aim of the study is to describe the prevalence of malnutrition based on low BMI, involuntary weight loss, and reduced food intake, in a Norwegian population of community-dwelling older adults and older adults living in nursing homes.

Methods: This population-based study is part of the fourth wave of the Trøndelag Health Study (HUNT4) and includes participants ≥70 years from the HUNT4 70+ cohort.

Effect of a one-year personalized intensive dietary intervention on body composition in colorectal cancer patients: Results from a randomized controlled trial.

Background & Aims: Changes in body composition may affect colorectal cancer (CRC) patient's risk of cancer recurrence, secondary cancer, and other chronic diseases. The suggested interventions for changes in body composition such as low muscle mass or high fat mass, are diet and physical activity. Nevertheless, there is limited evidence of how dietary intervention alone can impact body composition.

Associations of the 2018 World Cancer Research Fund/American Institute of Cancer Research (WCRF/AICR) cancer prevention recommendations with stages of colorectal carcinogenesis.

Background: While adherence to cancer prevention recommendations is linked to lower risk of colorectal cancer (CRC), few have studied associations across the entire spectrum of colorectal carcinogenesis. Here, we studied the relationship of the standardized 2018 World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) Score for cancer prevention recommendations with detection of colorectal lesions in a screening setting. As a secondary objective, we examined to what extent the recommendations were being followed in an external cohort of CRC patients.

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 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.

Low inter-rater reliability between nurses and researchers for the NRS-2002 screening tool for malnutrition in a hematological hospital ward.

Background & Aims: NRS-2002 is one of the recommended tools to screen hospitalized patients for malnutrition. NRS-2002 is considered as valid and reliable, but little is known about the inter-rater reliability between different groups of healthcare professionals. The aim of this study was to test the inter-rater reliability of the NRS-2002 tool between department nurses and researchers.

Agreement between GLIM and PG-SGA for diagnosis of malnutrition depends on the screening tool used in GLIM.

Background & Aim: The Global Leadership Initiative on Malnutrition (GLIM) has suggested a process for the diagnosis of malnutrition. The process consists of applying an existing screening tool for malnutrition screening, followed by malnutrition diagnostics, and finally categorization of malnutrition severity (moderate or severe) according to specific GLIM criteria. However, it is not known how well the GLIM process agrees with other diagnostic tools used in the current clinical practice.

Agreement between the GLIM criteria and PG-SGA in a mixed patient population at a nutrition outpatient clinic.

Background & Aims: The Global Leadership Initiative on Malnutrition (GLIM) criteria is a step-wise process including a screening tool of choice for risk assessment of malnutrition before assessment of diagnosis and grading of malnutrition severity. The agreement between GLIM and the established malnutrition assessment method Patient Generated-Subjective Global Assessment (PG-SGA) is uncertain. Also, several aspects of GLIM remain to be clearly defined.

Quantification of adipose tissues by Dual-Energy X-Ray Absorptiometry and Computed Tomography in colorectal cancer patients.

Background & Aims: Excess adipose tissue may affect colorectal cancer (CRC) patients' disease progression and treatment. In contrast to the commonly used anthropometric measurements, Dual-Energy X-Ray Absorptiometry (DXA) and Computed Tomography (CT) can differentiate adipose tissues. However, these modalities are rarely used in the clinic despite providing high-quality estimates.

Dietary Adjustments to Altitude Training in Elite Endurance Athletes; Impact of a Randomized Clinical Trial With Antioxidant-Rich Foods.

Altitude training stresses several physiological and metabolic processes and alters the dietary needs of the athletes. International Olympic Committee (IOC)'s Nutrition Expert Group suggests that athletes should increase intake of energy, carbohydrate, iron, fluid, and antioxidant-rich foods while training at altitude. We investigated whether athletes adjust their dietary intake according to the IOC's altitude-specific dietary recommendations, and whether an in-between meal intervention with antioxidant-rich foods altered the athletes' dietary composition and nutrition-related blood parameters (mineral, vitamin, carotenoid, and hormone concentrations).

Use of bioelectrical impedance analysis to monitor changes in fat-free mass during recovery from colorectal cancer- a validation study.

Background & Aims: Although previous research show high correlation between fat-free mass (FFM) measured by bioelectrical impedance analysis (BIA) and dual-energy X-ray absorptiometry (DXA), the validity of BIA to track longitudinal changes in FFM is uncertain. Thus, the aim of this study was to validate the ability of BIA to assess changes in FFM during 6 months of recovery from non-metastatic colorectal cancer (CRC).

Methods: A total of 136 women and men (50-80 years) with stage I-III CRC and a wide range of baseline FFM (35.

Nutritional treatment is associated with longer survival in patients with pancreatic disease and concomitant risk of malnutrition.

Background: Pancreatic diseases involve complex nutritional challenges. Despite this, conflicting evidence exists regarding the clinical relevance of detecting the risk of malnutrition and implementing systematic nutrition support for these patients. Thus, our aims were to investigate whether screening for malnutrition risk and initiating nutrition support are predictive of mortality for hospitalized patients with pancreatic diseases.

Effects of using the MyFood decision support system on hospitalized patients' nutritional status and treatment: A randomized controlled trial.

Background & Aims: Compliance to guidelines for disease-related malnutrition is documented as poor. The practice of using paper-based dietary recording forms with manual calculation of the patient's nutritional intake is considered cumbersome, time-consuming and unfeasible among the nurses and does often not lead to appropriate nutritional treatment. We developed the digital decision support system MyFood to deliver a solution to these challenges.

Effects of antioxidant-rich foods on altitude-induced oxidative stress and inflammation in elite endurance athletes: A randomized controlled trial.

Background: Various altitude training regimes, systematically used to improve oxygen carrying capacity and sports performance, have been associated with increased oxidative stress and inflammation. We investigated whether increased intake of common antioxidant-rich foods attenuates these processes.

Methods: In a randomized controlled trial, 31 elite endurance athletes (23 ± 5 years), ingested antioxidant-rich foods (n = 16), (> doubling their usual intake), or eucaloric control foods (n = 15) during a 3-week altitude training camp (2320 m).

Barriers and Facilitators for Implementing a Decision Support System to Prevent and Treat Disease-Related Malnutrition in a Hospital Setting: Qualitative Study.

Background: Disease-related malnutrition is a challenge among hospitalized patients. Despite guidelines and recommendations for prevention and treatment, the condition continues to be prevalent. The MyFood system is a recently developed decision support system to prevent and treat disease-related malnutrition.

Agreement between PG-SGA category and fat-free mass in colorectal cancer patients.

Background And Aims: Low fat-free mass (FFM) is associated with adverse outcomes in colorectal cancer (CRC) patients. Patient-Generated Subjective Global Assessment (PG-SGA) is a widely used tool developed to detect patients with malnutrition or at risk of malnutrition. The aim of this study was to investigate the agreement between PG-SGA category and FFM in patients with non-metastatic CRC.

Validation of two short questionnaires assessing physical activity in colorectal cancer patients.

Background: In order to investigate the impact of adherence to recommendations of physical activity and sedentary time on health outcomes in clinical trials, there is a need for feasible tools such as questionnaires that can give representative estimates of these measures. The primary aim of the present study was to validate two such questionnaires and their ability to estimate adherence to the recommendations of physical activity defined as moderate-to- vigorous physical activity or moderate physical activity of at least 150 min/week in colorectal cancer patients. Secondarily, self-reported sedentary time from the HUNT-PAQ was also evaluated.
