Poor nutrition status associated with low patient satisfaction six months into treatment for head and neck/esophageal cancer treatment: A prospective multicenter cohort study.

BACKGROUND: Patient-reported outcome measures have been associated with survival in oncology patients. Altered intake and malnutrition are common symptoms for patients treated for head and neck cancer and esophageal cancer (HNC/EC). The purpose of this study was to examine the relationship between patient-reported satisfaction with medical care and nutrition status. METHODS: This prospective cohort study collected data from 11 international cancer care sites. RESULTS: One hundred and sixtythree adult patients (n = 115 HNC; n = 48 EC) completed a patient satisfaction questionnaire (the Canadian Health Care Evaluation Project Lite) and were included. HNC/EC patient global satisfaction with medical care was 88.3/100 ± 15.3 at baseline and remained high at 86.6/100 ± 16.8 by 6 months (100 max satisfaction score). Poor nutrition status, as defined by the Patient-Generated Subjective Global Assessment Short Form, was associated with lower patient satisfaction with overall medical care, relationship with doctors, illness management, communication, and decision-making 6 months into treatment (P < 0.01). There was no difference in global satisfaction between patients who did and did not report swallowing difficulty (P = 0.99) and patients with and without feeding tube placement (P = 0.36). Patients who were seen by a dietitian for at least one nutrition assessment had global satisfaction with care that was 16.7 percentage points higher than those with no nutrition assessment (89.3 ± 13.8 vs 72.6 ± 23.6; P = 0.005) CONCLUSION: In HNC/EC patient-centered oncology care, decreasing malnutrition risk and providing access to dietitian-led nutrition assessments should be prioritized and supported to improve patient satisfaction and standard of care. Feeding tube placement did not decrease patient satisfaction with medical care.

Sarcopenic obesity in patients with head and neck cancer is predictive of critical weight loss during radiotherapy.

The impact of computed tomography-defined sarcopenia on outcomes in head and neck cancer has been well described. Sarcopenic obesity (SO) (depleted muscle mass combined with obesity) may pose a more serious risk than either condition alone. We investigated SO and its impact on survival and critical weight loss (≥ 5 %) in patients with head and neck cancer who received curative radiotherapy (± other modalities). Retrospective analysis of computed tomography cross-sectional muscle at cervical (C3), thoracic (T2) and lumbar (L3) regions was conducted. Patients were grouped by BMI and sarcopenia status based on established thresholds. A total of 413 patients were included for analysis, the majority having oropharyngeal carcinoma (52 %), and 56 % received primary concurrent chemoradiotherapy. The majority of the cohort (65 %) was overweight or obese (BMI ≥ 25 kg/m2). Sarcopenia was found in 43 %, with 65 % having SO (n 116), equating to 28 % of the whole cohort. Critical weight loss was experienced by 58 % (n 238). A significantly higher proportion of patients with SO experienced critical weight loss (n 70 v. 19, P < 0·001) and were four times more likely to do so during treatment (OR 4·1; 95 % CI 1·5, 7·1; P = 0·002). SO was not found to impact on overall or cancer-specific survival; however, in patients with sarcopenia, those with SO had better overall survival (median 9·1 v. 7·0 years; 95 % CI 5·2, 16·8; P = 0·021). SO at the time of presentation in patients with head and neck cancer is predictive of critical weight loss during treatment, and muscle evaluation can be useful in identifying patients at nutritional risk regardless of BMI and obvious signs of wasting.

Quantifying the severity of sarcopenia in patients with cancer of the head and neck.

BACKGROUND & AIMS: Existing skeletal muscle index (SMI) thresholds for sarcopenia are inconsistent, and do not reflect severity of depletion. In this study we aimed to define criterion values for moderate and severe skeletal muscle depletion based on the risk of mortality in a population of patients with head and neck cancer (HNC). Additionally, we aimed to identify clinical and demographic predictors of skeletal muscle depletion, evaluate the survival impact of skeletal muscle depletion in patients with minimal nutritional risk or good performance status, and finally, benchmarking SMI values of patients with HNC against healthy young adults. METHODS: Population cohort of 1231 consecutive patients and external validation cohorts with HNC had lumbar SMI measured by cross-sectional imaging. Optimal stratification determined sex-specific thresholds for 2-levels of SMI depletion (Class I and II) based on overall survival (OS). Adjusted multivariable regression analyses (tumor site, stage, performance status, age, sex, dietary intake, weight loss) determined relationships between 2-levels of SMI depletion and OS. RESULTS: Mean SMI (cm2/m2) was 51.7 ± 9.9 (males) and 39.8 ± 7.1 (females). The overall and sex-specific population demonstrated an increased risk of mortality associated with decreasing SMI. Sex-specific SMI (cm2/m2) depletion thresholds for 2-levels of muscle depletion determined by optimal stratification for males and females, respectively (male: 45.2-37.5, and <37.5; female: 40.9-34.2, and <34.2). In the overall population, Normal SMI, Class I and II SMI depletion occurred in 65.0%, 24.0%, and 11.0%, respectively. Median OS was: Normal SMI (114 months, 95% CI, 97.1-130.8); Class I SMI Depletion (42 months, 95% CI, 28.5-55.4), and Class II SMI Depletion (15 months, 95% CI, 9.8-20.1). Adjusted multivariable analysis compared with Normal SMI (reference), Class I SMI Depletion (HR, 1.49; 95% CI, 1.18-1.88; P < .001), Class II SMI Depletion (HR, 1.91; 95% CI, 1.42-2.58; P < .001). CONCLUSIONS: Moderate and severe SMI depletion demonstrate discrimination in OS in patients with HNC. Moderate and severe SMI depletion is prevalent in patients with minimal nutrition risk and good performance status. Benchmarking SMI values against healthy young adults exemplifies the magnitude of SMI depletion in patients with HNC and may be a useful method in standardizing SMI assessment.

Genome-guided purification of high amounts of the siderophore ornibactin and detection of potentially novel burkholdine derivatives produced by Burkholderia catarinensis 89T.

AIM: The increased availability of genome sequences has enabled the development of valuable tools for the prediction and identification of bacterial natural products. Burkholderia catarinensis 89T produces siderophores and an unknown potent antifungal metabolite. The aim of this work was to identify and purify natural products of B. catarinensis 89T through a genome-guided approach. MATERIALS AND METHODS: The analysis of B. catarinensis 89T genome revealed 16 clusters putatively related to secondary metabolism and antibiotics production. Of particular note was the identification of a nonribosomal peptide synthetase (NRPS) cluster related to the production of the siderophore ornibactin, a hybrid NRPS-polyketide synthase Type 1 cluster for the production of the antifungal glycolipopeptide burkholdine, and a gene cluster encoding homoserine lactones (HSL), probably involved in the regulation of both metabolites. We were able to purify high amounts of the ornibactin derivatives D/C6 and F/C8, while also detecting the derivative B/C4 in mass spectrometry investigations. A group of metabolites with molecular masses ranging from 1188 to 1272 Da could be detected in MS experiments, which we postulate to be new burkholdine analogs produced by B. catarinensis. The comparison of B. catarinensis BGCs with other Bcc members corroborates the hypothesis that this bacterium could produce new derivatives of these metabolites. Moreover, the quorum sensing metabolites C6-HSL, C8-HSL, and 3OH-C8-HSL were observed in LC-MS/MS analysis. CONCLUSION: The new species B. catarinensis is a potential source of new bioactive secondary metabolites. Our results highlight the importance of genome-guided purification and identification of metabolites of biotechnological importance.

Prevalence, risk factors, and clinical outcomes of vitamin C deficiency in adult hospitalized patients in high-income countries: a scoping review.

BACKGROUND: Assessment for vitamin C deficiency (VCD) is rarely undertaken in an acute hospital setting in high-income countries. However, with growing interest in VCD in community settings, there is emerging evidence investigating the prevalence and impact of VCD during hospitalization. OBJECTIVES: In this scoping review, the prevalence of VCD in adult hospitalized patients is explored, patient characteristics are described, and risk factors and clinical outcomes associated with VCD are identified. METHODS: A systematic scoping review was conducted in accordance with the PRISMA-ScR framework. The Ovid MEDLINE, Ovid Embase, Scopus, CINAHL Plus, Allied and Complementary Medicine Database, and the Cochrane Library databases were searched for interventional, comparative, and case-series studies that met eligibility criteria, including adult hospital inpatients in high-income countries, as defined by the Organization for Economic Co-operation and Development, that reported VCD prevalence using World Health Organization reference standards. These standards define VCD deficiency as plasma or serum vitamin C level <11.4 µmol/L, wholeblood level <17 µmol/L, or leukocytes <57 nmol/108 cells. RESULTS: Twenty-three articles were included, representing 22 studies. The cumulative prevalence of VCD was 27.7% (n = 2494; 95% confidence interval [CI], 21.3-34.0). High prevalence of VCD was observed in patients with severe acute illness and poor nutritional status. Scurvy was present in 48% to 62% of patients with VCD assessed in 2 studies (n = 71). Being retired (P = 0.015) and using excessive amounts of alcohol and tobacco (P = 0.0003) were independent risk factors for VCD (n = 184). Age was not conclusively associated with VCD (n = 631). Two studies examined nutrition associations (n = 309); results were inconsistent. Clinical outcomes for VCD included increased risk of frailty (adjusted odds ratio, 4.3; 95%CI, 1.33-13.86; P = 0.015) and cognitive impairment (adjusted odds ratio, 2.93; 95%CI, 1.05-8.19, P = 0.031) (n = 160). CONCLUSIONS: VCD is a nutritional challenge facing the healthcare systems of high-income countries. Research focused on early identification and treatment of patients with VCD is warranted.

Nutrition outcomes and treatment toxicities in patients with head and neck cancer receiving helical intensity-modulated radiotherapy.

BACKGROUND: Helical intensity-modulated radiotherapy (H-IMRT) provides excellent limitation of dose to tissues not requiring treatment, although acute toxicity still occurs. The present study aimed to determine how treatment-related acute toxicities affect nutrition outcomes in patients with head and neck cancer. METHODS: A prospective observational study was conducted in 194 patients undergoing curative intent H-IMRT with or without other treatment modalities. Weight outcomes (kg) and acute toxicity and dysphagia data were collected during treatment using Common Toxicity Criteria for Adverse Effects (CTCAE), version 4.0. RESULTS: Significant weight loss (> 10%) was observed in 30% of high nutritional risk patients and 7% of low nutritional risk patients. Nausea, adjusted for baseline dysphagia, in high nutritional risk patients and nausea, dysphagia and pharyngeal mucositis in low nutritional risk patients were significant factors in explaining the percentage loss in baseline weight to treatment completion. CONCLUSIONS: Significant weight loss remains an issue during treatment, despite improvements in radiotherapy technology and high-level multidisciplinary care.

Thoracic skeletal muscle index is effective for CT-defined sarcopenia evaluation in patients with head and neck cancer.

PURPOSE: Computed tomography (CT)-defined sarcopenia, as a measurement of low skeletal muscle (SM), is a poor prognostic indicator in patients with head and neck cancer (HNC), independent of weight or nutritional status. We used SM measures at the second thoracic vertebra (T2) to determine T2-SM index (SMI) thresholds for sarcopenia, and investigate the impact of low T2-SMI on overall survival (OS), and weight loss during radiotherapy (RT). METHODS: Adult patients with newly diagnosed HNC with a diagnostic PET-CT or RT planning CT scan were included. SM was analysed at T2 and a model applied to predict SM at L3. T2-SMI thresholds for sarcopenia were established with predicted measures, stratified by BMI and sex. Impact of sarcopenia and low T2-SMI on OS and weight loss during RT was investigated. RESULTS: A total of 361 scans were analysed (84% males, 54% oropharynx tumours). Sarcopenia was found in 49%, demonstrating worse OS (p = 0.037). T2-SMI cutoff values were: females-74 cm2/m2 [area under the curve (AUC): 0.89 (95%CI 0.80-0.98)], males (BMI < 25)-63 cm2/m2 [AUC 0.93 (95%CI 0.89-0.96)], males (BMI ≥ 25)-88cm2/m2 [AUC 0.86 (95%CI 0.78-0.93)]. No difference in OS with T2-SMI categories. Lowest T2-SMI quartile of < 63 cm2/m2 demonstrated worse OS (p = 0.017). Weight loss during RT was higher in patients; who were not sarcopenic (6.2% vs 4.9%, p = 0.023); with higher T2-SMI (6.3% vs 4.9%, p = 0.014) and; in the highest quartiles (3.6% vs 5.7% vs 7.2%, p < 0.001). CONCLUSIONS: These T2-SMI thresholds are effective in assessing CT-defined sarcopenia in HNC. Further assessment of clinical application is warranted.

Nutritional status and post-operative complications in patients undergoing surgery for advanced pharyngeal or laryngeal cancer.

PURPOSE: Malnutrition is an important prognostic indicator of post-operative outcomes in patients undergoing surgery for head and neck cancer, however, limited studies utilize validated nutrition assessment tools to accurately assess risk. The aim of this study was to determine the relationship between nutritional status on post-operative complications and length of stay for patients undergoing either a laryngectomy, pharyngectomy or pharyngolaryngectomy for head and neck cancer. METHODS: Patients with head and neck cancer undergoing a laryngectomy, pharyngectomy or pharyngolaryngectomy at a tertiary hospital in Australia were eligible for this retrospective cohort study (n = 40). Nutritional status was assessed by the dietitian on admission using the validated Subjective Global Assessment tool. Clinical outcomes were collected via retrospective chart review and included length of stay and post-operative complications. RESULTS: Pre-operative malnutrition incidence was 40%. Malnourished patients had higher incidences of any type of complication (57% vs 44%, p = 0.013) and pressure injury (86% vs 14%, p = 0.011) compared to well-nourished patients. Well-nourished patients had a clinically important shorter median length of stay compared to malnourished patients (17.5 vs 20 days). CONCLUSION: Early identification and management of malnutrition is essential to minimize risk of post-operative complications and reduce length of stay and should be considered a key component of prehabilitation programs.

An Umbrella Review and Meta-analysis of Interventions, Excluding Enteral and Parenteral Nutrition, Initiated in the Hospital for Adults with or at Risk of Malnutrition.

BACKGROUND: Multiple systematic reviews and meta-analyses (SRMAs) on various nutritional interventions in hospitalized patients with or at risk of malnutrition are available, but disagreements among findings raise questions about their validity in guiding practice. OBJECTIVES: We conducted an umbrella review (a systematic review of systematic reviews in which all appropriate studies included in SRMAs are combined) to assess the quality of reviews, identify the types of interventions available (excluding enteral and parenteral nutrition), and re-analyze the effectiveness of interventions. METHODS: The databases MEDLINE/PubMed, CINAHL, Embase, The Cochrane Library, and Google Scholar were searched. AMSTAR-2 was used for quality assessment and GRADE for certainty of evidence. Updated meta-analyses with risk of bias (ROB) by Cochrane ROB 2.0 were performed. Pooled effects were reported as relative risk (RR), with zero-events and publication bias adjustments, and trial sequential analysis (TSA) performed for mortality, readmissions, complications, length of stay, and quality of life. RESULTS: A total of 66 randomized controlled trials were cited by the 19 SRMAs included in this umbrella review, and their data extracted and analyzed. Most clinical outcomes were discordant with variable effect sizes in both directions. In trials with low ROB, interventions targeting nutritional intake reduce mortality at 30 d (15 studies, n: 4156, RR: 0.72, 95% CI: 0.55, 0.94, P: 0.02, I2: 6%, Certainty: High), 6 mo (27 studies, n: 6387, RR: 0.81, 95% CI: 0.71, 0.92, P = 0.001, I2: 4%, Certainty: Moderate), and 12 mo (27 studies, n: 6387, RR: 0.80, 95% CI: 0.67, 0.95, P: 0.01, I2: 33%, Certainty: Moderate), with TSA verifying an adequate sample size and robustness of the meta-analysis. CONCLUSION: Existing evidence is sufficient to show that nutritional intervention is effective for mortality outcomes at 30 d, 6 mo, and 12 mo. Future clinical trials should focus on the effect of nutritional interventions on other clinical outcomes. TRIAL REGISTRATION NUMBER: The protocol is registered on PROSPERO (CRD42022341031).

The use of the second thoracic vertebral landmark for skeletal muscle assessment and computed tomography-defined sarcopenia evaluation in patients with head and neck cancer.

BACKGROUND: The cross-sectional area (CSA) of skeletal muscle (SM) at the third lumbar vertebra (L3) is used to determine computed tomography (CT)-defined sarcopenia. We investigated the feasibility of SM assessment at the second thoracic vertebra (T2) in patients with head and neck cancer (HNC). METHODS: Diagnostic PET-CT scans were used to develop a prediction model for L3-CSA using T2-CSA. Effectiveness of the model and cancer-specific survival (CSS) were investigated. RESULTS: Scans of 111 patients (85% male) were evaluated. The predictive formula: L3-CSA (cm2 ) = 174.15 + [0.212 × T2-CSA (cm2 )] - [40.032 × sex] - [0.928 × age (years)] + [0.285 × weight (kg)] had good correlation r = 0.796, ICC = 0.882 (p < 0.001). SM index (SMI) mean difference (bias) was -3.6% (SD 10.2, 95% CI -8.7% to 1.3%). Sensitivity (82.8%), specificity (78.2%), with moderate agreement (ƙ = 0.540, p < 0.001). Worse 5-year CSS with lower quartile T2-SMI (51%, p = 0.003). CONCLUSIONS: SM at T2 can be effectively used for CT-defined sarcopenia evaluation in HNC.

Impact of sarcopenia and myosteatosis on survival outcomes for patients with head and neck cancer undergoing curative-intent treatment.

Malnutrition and sarcopenia are prevalent in patients with head and neck squamous cell carcinoma (HNSCC). Pre-treatment sarcopenia and adverse oncological outcomes in this population are well described. The impact of myosteatosis and post-treatment sarcopenia is less well known. Patients with HNSCC (n = 125) undergoing chemoradiotherapy, radiotherapy alone and/or surgery were assessed for sarcopenia and myosteatosis, using cross-sectional computed tomography (CT) imaging at the third lumbar (L3) vertebra, at baseline and 3 months post-treatment. Outcomes were overall survival (OS) at 12 months and 5 years post-treatment. One hundred and one participants had a CT scan evaluable at one or two time points, of which sixty-seven (66 %) participants were sarcopenic on at least one time point. Reduced muscle attenuation affected 93 % (n = 92) pre-treatment compared with 97 % (n = 90) post-treatment. Five-year OS favoured those without post-treatment sarcopenia (hazard ratio, HR 0·37, 95 % CI 0·16, 0·88, P = 0·06) and those without both post-treatment myosteatosis and sarcopenia (HR 0·33, 95 % CI 0·13, 0·83, P = 0·06). Overall, rates of myosteatosis were high at both pre- and post-treatment time points. Post-treatment sarcopenia was associated with worse 5-year OS, as was post-treatment sarcopenia in those who had myosteatosis. Post-treatment sarcopenia should be evaluated as an independent risk factor for decreased long-term survival post-treatment containing radiotherapy (RT) for HNSCC.

Comparison of Skeletal Muscle Changes at Three Vertebral Levels Following Radiotherapy in Patients With Oropharyngeal Carcinoma.

Evaluation of skeletal muscle (SM) depletion, or sarcopenia, utilizes the cross-sectional area (CSA) of computed tomography (CT) scans at the lumbar level L3. However, alternate vertebral landmarks are used in patients with head and neck cancer due to scan unavailability. Muscle changes following radiotherapy at cervical (C3) and thoracic (T2) levels were compared to L3 in patients with oropharyngeal carcinoma. Muscle density data were derived retrospectively from diagnostic PET-CT scans at C3, T2 and L3 pretreatment, and up to six months post. CSA changes were compared to L3 in scans of 33 patients (88% male, mean age 61 (SD 8.5) years). On matched pair analysis; mean L3-CSA change -12.1 cm2 (SD 9.7, 95%CI -15.5 to -8.6, and p < 0.001), T2-CSA -30.5 cm2 (SD 34.8, 95%CI -42.8 to -18.1, and p < 0.001) and C3-CSA +2.1 cm2 (SD 4.1, 95%CI 0.63 to 3.5, and p < 0.00). No difference was found in the percentage change of T2-CSA with L3-CSA (mean -2.2%, SD 10.6, 95%CI -6.0 to 1.6, and p = 0.240), however, was significantly different to C3-CSA (mean 13.2%, SD 11.6, 95%CI 9.1 to 17.3, and p < 0.001). Results suggest SM at C3 does not change proportionately and may not be a reliable representation of whole-body SM change over time.

Improving patient and carer access to information and support through head and neck cancer treatment and survivorship using experience-based co-design.

BACKGROUND: Previous studies have highlighted the unmet nutritional and supportive care needs of patients with head and neck cancer (HNC) and their carers from diagnosis and throughout the treatment and survivorship period. The aim of this study was to bring patients, carers and healthcare professionals together to co-design a framework to improve access to nutrition information and support for patients and carers with HNC from diagnosis and throughout the treatment and survivorship period. METHODS: Using experience-based co-design (EBCD), semistructured individual interviews were conducted with patients, carers and healthcare professionals to understand their experiences in accessing information and support outside of the hospital environment. Feedback events and co-design workshops were held to prioritise areas for service improvement. RESULTS: Participants (10 patients, 7 carers and 15 healthcare professionals) highlighted the importance of having consistent information and support recommendations from the multidisciplinary team. The two key areas for improvement identified through group and workshop events were linking reputable HNC resources to a HNC portal on the hospital website and the development of a series of short podcasts and video blogs with fact sheets attached presented by members of the multidisciplinary team, patients and carers at four time points spanning pretreatment and throughout the survivorship period. CONCLUSIONS: Using EBCD has enabled the co-design of a framework for resource development with patients, carers and healthcare professionals to improve access to information and resources to support nutrition intake and supportive care needs for patients with HNC with their carers. Development and implementation of resources and evaluation of outcomes is ongoing.

A prediction model for skeletal muscle evaluation and computed tomography-defined sarcopenia diagnosis in a predominantly overweight cohort of patients with head and neck cancer.

PURPOSE: This study investigates the feasibility of computed tomography (CT)-defined sarcopenia assessment using a prediction model for estimating the cross-sectional area (CSA) of skeletal muscle (SM) in CT scans at the third lumbar vertebra (L3), using measures at the third cervical level (C3) in a predominantly overweight population with head and neck cancer (HNC). METHODS: Analysis was conducted on adult patients with newly diagnosed HNC who had a diagnostic positron emission tomography-CT scan. CSA of SM in CT images was measured at L3 and C3 in each patient, and a predictive formula developed using fivefold cross-validation and linear regression modelling. Correlation and agreement between measured CSA at L3 and predicted values were evaluated using intraclass correlation coefficients (ICC) and Bland-Altman plot. The model's ability to identify sarcopenia was investigated using Cohen's Kappa (k). RESULTS: A total of 109 patient scans were analysed, with 64% of the cohort being overweight or obese. The prediction model demonstrated high level of correlation between measured and predicted CSA measures (ICC 0.954, r = 0.916, p < 0.001), and skeletal muscle index (SMI) (ICC 0.939, r = 0.883, p < 0.001). Bland-Altman plot showed good agreement in SMI, with mean difference (bias) = 0.22% (SD 8.65, 95% CI - 3.35 to 3.79%), limits of agreement (- 16.74 to 17.17%). The model had a sensitivity of 80.0% and specificity of 85.0%, with moderate agreement on sarcopenia diagnosis (k = 0.565, p = 0.004). CONCLUSION: This model is effective in predicting lumbar SM CSA using measures at C3, and in identifying low SM in a predominately overweight group of patients with HNC.

A Multi-Site, International Audit of Malnutrition Risk and Energy and Protein Intakes in Patients Undergoing Treatment for Head Neck and Esophageal Cancer: Results from INFORM.

Patients with foregut tumors are at high risk of malnutrition. Nutrition care focuses on identifying individuals at risk of malnutrition and optimizing nutrient intake to promote the maintenance of body weight and lean body mass. This multi-center prospective, longitudinal study audited nutrition care practices related to screening for risk of malnutrition (Patient-Generated Subjective Global Assessment Short Form; PG-SGA SF), and nutrition interventions prescribed (route; adequacy of energy and protein intakes). Audits occurred at four time periods: baseline (before treatment) and at 2, 4, and 6 months after starting cancer treatment; 170 patients (esophageal (ESO; n = 51); head and neck (HN; n = 119)) were enrolled. Nutrition risk (PG-SGA SF score ≥ 4) was prevalent at every time period: HN (baseline: 60%; 6 months 66%) and ESO (77%; 72%). Both groups had significant (p < 0.001) weight losses over the 6 month audit period (HN = 13.2% ESO = 11.4%). Enteral nutrition (EN) was most likely to be prescribed at 2 months for HN and at 4 and 6 months for ESO. Target prescribed energy and protein intakes were not met with any nutrition intervention; although adequacy was highest for those receiving EN. Nutrition care practices differed for HN and ESO cancers and there may be time points when additional nutrition support is needed.

A qualitative comparison of the nutrition care experiences of carers supporting patients with head and neck cancer throughout surgery and radiation treatment and survivorship.

PURPOSE: To understand and compare the nutrition care experiences of carers supporting patients throughout surgery and radiation treatment for head and neck cancer (HNC) to inform changes to service delivery in the inpatient and outpatient setting to ensure carers needs in their supportive role throughout the treatment and survivorship period are met. METHODS: As part of a larger study, narrative interviews were completed with fourteen carers of patients diagnosed with HNC at 2 weeks, 3 months and 12 months post-treatment completion. Reflexive thematic analysis was used to interpret and understand differences in carer experiences of nutrition care between surgery and radiation treatment. RESULTS: Two main themes across each treatment modality were identified: (1) access to information and support from healthcare professionals and (2) adjustment to the physical and psychological impact of treatment. CONCLUSION: This study highlights the increasing need to ensure carers are included in the provision of nutrition information and support to patients throughout and beyond their treatment trajectory. Having structured support available to patients and carers throughout radiation treatment meant that carer needs were reduced. However, without the opportunity for structured support in the inpatient setting, many carers expressed high care needs in supporting patients in the post-surgical phase. IMPLICATIONS FOR CANCER SURVIVORS: Providing carers with access to structured support for nutrition care in the inpatient and outpatient setting can reduce their supportive care needs throughout the treatment and survivorship period.

Prevalence and Impact of Computed Tomography-Defined Sarcopenia on Survival in Patients with Human Papillomavirus-Positive Oropharyngeal Cancer: A Systematic Review.

Sarcopenia is a known independent prognostic factor for decreased survival in patients with head and neck cancer; yet, its importance for the growing number of younger patients diagnosed with human papillomavirus (HPV)-positive oropharyngeal carcinoma (OPC+) has not been established. This systematic literature review aimed to determine the prevalence and impact of computed tomography (CT)-defined sarcopenia on survival outcomes for adult OPC+ patients (>18 y) undergoing any treatment modality. Prospective studies were searched using PubMed, Embase, CENTRAL, CINAHL, and Web of Science up until and including February 2022. Bias was assessed using the Quality In Prognosis Studies (QUIPS) tool, and certainty of evidence using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. In total, 9 studies (total pooled OPC+ patients, n  = 744) were identified and included in this review; 2 at low, 6 at moderate, and 1 at high risk of bias. All studies varied in sarcopenia assessment methods and skeletal muscle index threshold cutoff values. These studies demonstrated the cumulative prevalence of sarcopenia for OPC+ patients to be 42.9% (95% CI: 37.8%, 47.9%). While overall survival (3 studies, n = 253) and progression-free survival (1 study, n = 117) was lower in sarcopenic OPC+ patients, this was not statistically significant. GRADE certainty of evidence for impact of pretreatment sarcopenia on overall survival was low and progression-free survival was very low. Although these studies showed there to be a high prevalence of pretreatment sarcopenia in patients with OPC+, which may decrease survival, the impact on progression-free survival is very uncertain. Further, high-quality research utilizing consistent sarcopenia definitions and assessment methods that are conducted specifically in OPC+ is required to strengthen evidence certainty and determine if sarcopenia is an independent prognostic factor for this population.

Smoking and other health factors in patients with head and neck cancer.

BACKGROUND: Information on smoking and other health factors in head and neck cancer (HNC) patients throughout treatment, follow-up and survivorship is limited. This study explores patterns of multiple health factors during radiotherapy (RT) and naturalistic long-term follow-up in a convenience sample of patients with HNC. METHODS: Smoking, alcohol use and depression were measured at baseline, 4 and 12 weeks post RT for a sub-group of 99 patients who participated in a randomised controlled trial and completed long-term follow-up. These factors plus healthy eating, physical activity and fatigue are also reported from the long-term follow-up component. Smoking was measured by self-report and biochemically, whilst all other variables were by self-report. Where variables were assessed at multiple time points logistic mixed effects regression models determined within-person changes over time. RESULTS: There were important discrepancies between self-reported (4-7%) and biochemically verified (13-29%) rates of smoking. Rates of smoking and hazardous alcohol intake were significantly increased at follow-up compared to baseline. Depression rates were observed to be higher at end of RT compared to baseline. At long-term follow-up, fatigue was common and co-occurred with suboptimal healthy eating and hazardous alcohol use. CONCLUSION: Clinically important levels of smoking and alcohol consumption post RT in this sample suggest possible targets for intervention beyond treatment into long-term follow-up of patients.

Effectiveness of dietary counseling with or without nutrition supplementation in hospitalized patients who are malnourished or at risk of malnutrition: A systematic review and meta-analysis.

BACKGROUND: Nutrition support is associated with improved survival and nonelective hospital readmission rates among malnourished medical inpatients; however, limited evidence supporting dietary counseling is available. We intend to determine the effect of dietary counseling with or without oral nutrition supplementation (ONS), compared with standard care, on hospitalized adults who are malnourished or at risk of malnutrition. METHODS: We searched MEDLINE/PubMed, CINAHL, Embase, Scopus, The Cochrane Library, and Google Scholar for studies listed from January 1, 2011, to August 31, 2021. Meta-analysis was performed to obtain pooled risk ratios (RRs) and 95% CIs to estimate the effect. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system was used to assess the certainty of the evidence. RESULTS: Sixteen studies were identified. Compared with standard care, dietary counseling with or without ONS probably does not reduce inpatient rates of 30-day mortality (RR = 1.24; 0.60-2.55; I2 = 45%; P = 0.56; moderate certainty), slightly reduces 6-month mortality (RR = 0.83; 0.69-1.00; I2 = 16%; P = 0.06; high certainty), reduces complications (RR = 0.85; 0.73-0.98; I2 = 0%; P = 0.03; high certainty), and may slightly reduce readmission (RR = 0.83; 0.66-1.03; I2 = 55%; P = 0.10; low certainty) but may not reduce length of stay (mean difference: -0.75 days; -1.66-0.17; I2 = 70%; P = 0.11; low certainty). Intervention may result in slight improvements in nutrition status/intake and weight/body mass index (low certainty). CONCLUSIONS: There is an increase in the certainty of evidence regarding the positive impact of dietary counseling on outcomes. Future studies should standardize and provide details/frequencies of counseling methods and ONS adherence to determine dietary counseling effectiveness.
