Chronic Nutrition Impact Symptoms Are Associated with Decreased Functional Status, Quality of Life, and Diet Quality in a Pilot Study of Long-Term Post-Radiation Head and Neck Cancer Survivors

Anti-Radiofibrosis Effect of Dicliptera chinensis Polysaccharide on Rat Dermal Fibroblasts Via The TGF-β1/Smads/CTGF Signaling Pathway

OBJECTIVE

Radiotherapy is an effective treatment for head and neck cancer; however, irradiated normal tissues are inevitably damaged, resulting in skin radioactive fibrosis. Dicliptera chinensis polysaccharide (DCP), the primary active compound extracted from the natural medicinal Dicliptera chinensis, exhibits antioxidant, anti-inflammatory, and anti-radiation properties. In this study, we investigated the protective effects of DCP against radioactive fibrosis in rat dermal fibroblasts (RDF) and explored the underlying mechanisms involved.

DESIGN

RDFs were treated with DCP, and the CCK8 assay was used to determine cellular activity. The rates of apoptosis and cell cycle progression were detected using flow cytometry. mRNA expression levels were quantified using real-time polymerase chain reaction. Protein levels were analysed through Western blotting and immunofluorescence staining RESULTS: DCP reduced radiation-induced apoptosis, and the cell cycle G2/M arrest was alleviated. Furthermore, DCP decreased the expression of key fibrosis-related markers, including α-SMA, TGF-β1, Smad3, and CTGF.

CONCLUSION

DCP exhibits a protective effect against radiation-induced fibrosis.

Symptom Patterning Across the Cancer Care Trajectory for Patients Receiving Chemoradiation for Head and Neck Cancer: A Retrospective Longitudinal Study Using Latent Transition Analysis

BACKGROUND

Patients with head and neck cancer (HNC) experience a multitude of symptoms because of the tumor and its treatment.

OBJECTIVE

To identify the symptom patterns present in cancer treatment and survivorship periods for patients with HNC using latent class analysis.

METHODS

A retrospective longitudinal chart review was conducted to examine symptoms reported by patients who received concurrent chemoradiation for HNC in a regional Northeastern United States cancer institute. Latent class analysis was performed to identify the latent classes present across multiple timepoints during treatment and survivorship for the most commonly reported symptoms.

RESULTS

In 275 patients with HNC, the latent transition analysis revealed 3 latent classes for both treatment and survivorship periods: (1) mild, (2) moderate, and (3) severe symptoms. Patients were more likely to report a greater number of symptoms in a more severe latent class. During treatment, moderate and severe classes had representation of all most common symptoms: pain, mucositis, taste alterations, xerostomia, dysphagia, and fatigue. Different symptom patterns emerged for survivorship, with prominence of taste alterations and xerostomia across all classes, and all symptoms present in the severe class. The probability of symptom expression varied more in the survivorship period compared with the treatment period.

CONCLUSIONS

Patients reported numerous symptoms during active treatment persisting into survivorship. Patients tended to transition to more severe symptomatology as treatment progressed and to more moderate symptomatology as survivorship evolved.

IMPLICATIONS FOR PRACTICE

Examining the trend of persistent moderate symptomatology into survivorship is useful to optimize symptom management.

A qualitative analysis of nutritional needs and dietary changes during cancer treatment in Ireland

INTRODUCTION

Cancer and its associated side effects can cause changes in dietary intakes of people with cancer due to a variety of nutrition impact symptoms. These symptoms can lead to suboptimal dietary intakes which negatively affect muscle mass and therefore survivorship. The aim of this qualitative study was to assess the nutrition needs and dietary changes made by cancer patients in Ireland.

METHODS

Online focus groups were completed with cancer patients and caregivers, and demographic information was collected via an online questionnaire. An inductive thematic analysis approach was utilised to derive themes and subthemes from the data.

RESULTS

Four online focus groups were held with cancer patients and caregivers (n = 15) which reflected 18 total cancer experiences. Novel themes identified from this research included that symptoms were varied and transient-coming and going rapidly-and that patients were not satisfied with dietetic and broader nutrition services provided by hospitals. Themes that aligned with previous research were the severity and variety of nutrition impact symptoms and the variety of both evidence-based and non-evidence-based nutrition strategies used by patients to overcome nutrition impact symptoms, as general coping strategies, and potentially due to the belief that nutrition can be curative.

CONCLUSION

Treatment of nutrition impact symptoms must be rapid and responsive. The development of responsive self-management resources such as booklets and apps for patients is likely to be valuable to ensure that patients can access support for their nutrition impact symptoms as-and when-they occur. Nutrition support must be integrated across the multi-disciplinary team to optimise trust in nutrition strategies.

Adequate calorie and protein administration via enteral nutrition may contribute to improved 30-day survival in patients with solid tumors at nutritional risk

BACKGROUND

Patients with cancer receiving adequate enteral nutrition (EN) have improved clinical outcomes. Unfortunately, discrepancies may exist between the amounts prescribed and received. This study aimed to investigate: (1) the receiving exclusive EN, (2) the relationship between inadequacy and unfavorable outcomes, and (3) the impact of inadequate EN administration on the survival of patients with cancer.

METHODS

This study included hospitalized patients with solid tumors who exclusively received EN and were evaluated using data extracted from electronic medical records. Nutritional risk was evaluated using Nutritional Risk Screening (NRS - 2002). EN adequacy was assessed from days 3-7 of hospitalization. Calorie and protein delivery by EN was classified as adequate (≥80 % of EN administration) or inadequate (<80 % of EN administration). Data were analyzed using dispersion and Bland-Altman plots, Pearson's chi-square and Fisher's exact tests, and Kaplan-Meier survival curves.

RESULTS

A total of 114 patients were evaluated (63.9 ± 13.1 years of age, 67.5 % male, 32.5 % with head and neck cancer, and 86.8 % at nutritional risk). During the 5-day evaluation period, only 14 % of the patients received the mean volume, proteins, and calories according to the EN prescription. A relationship was observed between inadequate EN (<80 %) and 30-day in-hospital mortality. This result was confirmed by Kaplan-Meier survival analysis (p = 0.020), which showed a survival benefit in patients at nutritional risk who received adequate calories and protein.

CONCLUSION

This study demonstrated significant caloric and protein deficits related with EN. Furthermore, adequate calorie and protein administration could contribute to improved survival in patients with cancer who are at a risk of malnutrition, however, randomized controlled trials are required to confirm whether adequate calorie administration could contribute to improved survival.

Managing eating problems after cancer

Cancer treatment can cause food-limiting eating problems that persist or arise months or years after treatment, with negative consequences for the survivor's nutritional status, physical and social function, and quality of life. Hence, post-treatment follow-up and cancer rehabilitation services should aim to support the survivor in managing treatment-related eating problems. This narrative review summarizes the evidence on and provides an overview of interventions to manage eating problems after cancer. Interventions are grouped into four: 1) food-based interventions, including alternating food/fluids and experimenting through the trial-and-error strategy to find tolerated foods; 2) eating behavioral interventions, including instructions on swallowing techniques, posture, and utensils; 3) psychosocial support interventions, including group-based interventions and interventions including relatives; and 4) physical interventions, including exercises to improve dysphagia or trismus. While physical interventions are supported by evidence from several intervention studies, few studies evaluating the effect of other types of interventions in survivors were identified. Instead, qualitative and observational data providing insights on experiences of and coping strategies applied by survivors with eating problems underpin the need for the other types of interventions. Since existing research primarily focuses on survivors of head and neck cancer, future studies on the organization and effects of interventions aimed at managing eating problems among different groups of survivors are relevant.

Severity of Liver Fibrosis Is Associated with the Japanese Diet Pattern and Skeletal Muscle Mass in Patients with Nonalcoholic Fatty Liver Disease

It is not fully clear as to which dietary patterns are associated with the pathogenesis of nonalcoholic fatty liver disease (NAFLD) in Asia. We conducted a cross-sectional study of 136 consecutively recruited patients with NAFLD (49% female, median age 60 years). Severity of liver fibrosis was assessed using the Agile 3+ score, a recently proposed system based on vibration-controlled transient elastography. Dietary status was assessed using the 12-component modified Japanese diet pattern index (mJDI12). Skeletal muscle mass was assessed by bioelectrical impedance. Factors associated with intermediate-high-risk Agile 3+ scores and skeletal muscle mass (75th percentile or higher) were analyzed by multivariable logistic regression. After adjustment for confounders, such as age and sex, the mJDI12 (OR: 0.77; 95% CI: 0.61, 0.99) and skeletal muscle mass (75th percentile or higher) (OR: 0.23; 95% CI: 0.07, 0.77) were significantly associated with intermediate-high-risk Agile 3+ scores. Soybeans and soybean foods were significantly associated with skeletal muscle mass (75th percentile or higher) (OR: 1.02; 95% CI: 1.00, 1.04). In conclusion, the Japanese diet pattern was associated with the severity of liver fibrosis in Japanese patients with NAFLD. Skeletal muscle mass was also associated with the severity of liver fibrosis, and intake of soybeans and soybean foods.

Dietary Carotenoids in Head and Neck Cancer-Molecular and Clinical Implications

Head and neck cancer (HNC) is one of the most common cancers in the world according to GLOBCAN. In 2018, it was reported that HNC accounts for approximately 3% of all human cancers (51,540 new cases) and is the cause of nearly 1.5% of all cancer deaths (10,030 deaths). Despite great advances in treatment, HNC is indicated as a leading cause of death worldwide. In addition to having a positive impact on general health, a diet rich in carotenoids can regulate stages in the course of carcinogenesis; indeed, strong epidemiological associations exist between dietary carotenoids and HNS, and it is presumed that diets with carotenoids can even reduce cancer risk. They have also been proposed as potential chemotherapeutic agents and substances used in chemoprevention of HNC. The present review discusses the links between dietary carotenoids and HNC. It examines the prospective anticancer effect of dietary carotenoids against intracellular cell signalling and mechanisms, oxidative stress regulation, as well as their impact on apoptosis, cell cycle progression, cell proliferation, angiogenesis, metastasis, and chemoprevention; it also provides an overview of the limited preclinical and clinical research published in this arena. Recent epidemiological, key opinion-forming systematic reviews, cross-sectional, longitudinal, prospective, and interventional studies based on in vitro and animal models of HNC also indicate that high carotenoid content obtained from daily supplementation has positive effects on the initiation, promotion, and progression of HNC. This article presents these results according to their increasing clinical credibility.
