Background: Patients with stage I-III non-small cell lung cancer (NSCLC) are often nutritionally depleted and therefore at high-risk for treatment complications. Identifying these patients before the start of treatment is important to initiate preventive interventions for better treatment outcomes. This study aimed to evaluate which outcome variables of pretreatment nutritional assessments are associated with posttreatment complications in patients with stage I-III NSCLC, as well as to identify cut-off values for clinical risk stratification.
Methods: In this systematic review, PubMed, Embase, and Cinahl databases were searched for eligible studies published up to March 2021. Studies describing the association between pretreatment nutritional assessment and treatment complications in patients with NSCLC were included. Methodological quality of the included studies was assessed using the Newcastle-Ottawa Scale for cohort studies.
Results: A total of 23 studies were included, which merely focused on surgical treatment for NSCLC. Methodological quality was poor in thirteen studies (57%). Poor outcomes of body mass index, sarcopenia, serum albumin, controlling nutritional status, prognostic nutrition index, nutrition risk score, and (geriatric) nutrition risk index were associated with a higher risk for treatment complications. Cut-off values for pretreatment nutritional assessment were reported in a limited number of studies and were inconsistent.
Conclusion: Poor outcomes of pretreatment nutritional assessments are associated with a higher risk for posttreatment complications. Further research is needed on the ability of easy-to-use pretreatment nutritional assessments to accurately identify patients who are at high risk for treatment complications, as high-risk patients may benefit from pretreatment interventions to improve their nutritional status.

Patient-reported quality of life and adherence outcomes after integrating exclusive liquid meal replacement in patients with head and neck cancer undergoing chemoradiation: results from a phase II study.

Objectives: Preventing malnutrition during chemoradiation (CRT) for head and neck cancer is critical maximizing quality of life (QOL). We sought to assess patient-reported QOL outcomes after integrating exclusive liquid meal replacement with Soylent, a novel meal replacement agent, in patients with head and neck cancer undergoing CRT.
Methods: Patients undergoing definitive or adjuvant concurrent CRT for locally advanced head and neck cancer enrolled on our single-institution, prospective phase II protocol evaluating nutritional replacement with Soylent.

We previously used high pressure liquid chromatography (HPLC) coupled with Se-specific inductively coupled plasma mass spectrometry (ICP-MS) and molecule specific (ESI Orbitrap MS/MS) detection to study the increase in liver Se in turkeys and rats supplemented as selenite in high-Se (5 µg Se/g diet) and adequate-Se diets. We found that far more Se is present as selenosugar (seleno-N-acetyl galactosamine) than is present as selenocysteine (Sec) in true selenoproteins. In high-Se liver, the increase in liver Se was due to low molecular weight (LMW) selenometabolites as glutathione-, cysteine- and methyl-conjugates of the selenosugar, but also as high molecular weight (HMW) species as selenosugars decorating general proteins via mixed-disulfide bonds.

Oxidative stress is considered to be a major cause of numerous intestinal diseases, and taxifolin (TA) possesses a variety of pharmacological properties that promote health and prevent disease. This study intends to determine the ability of TA to alleviate oxidative stress induced by diquat (DIQ) in porcine intestinal epithelial cells (IPEC-J2 cells). After being pretreated with 150 μM TA for 24 h, IPEC-J2 cells were treated with 0.

Introduction: Inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS) are chronic disorders of the gastrointestinal tract associated with gut microbiota dysbiosis and inflammation. Serum-derived bovine immunoglobulin (SBI) is used to manage IBS and IBD and has shown prebiotic-like effects in ex vivo models. Re-establishing a healthy gut microbiome with novel treatments like SBI could help treat the underlying causes of these diseases leading to higher and sustained patient response.
