RESUMO

INTRODUCTION: Medicinal cannabis might have a role in supporting the mental health of people with cancer. This systematic review and meta-analysis examined the efficacy and safety of medicinal cannabis, compared with any control, as an intervention for depression, anxiety, and stress symptoms in people living with cancer. A secondary aim was to examine the effect of low versus high Δ9-tetrahydrocannabinol (THC) dose on these outcomes. METHODS: Five databases were systematically searched, and complemented with a snowball search from inception to May 2023, for any type of interventional study that included humans of any age with any cancer type. Primary outcomes were incidence and severity of depression, anxiety, and stress symptoms. Secondary outcomes were mood, cognition, quality of life, appetite, nutrition status, gastrointestinal symptoms, and adverse events. Data were pooled using Review Manager. Evidence was appraised using Cochrane risk of bias tools. Confidence in the estimated effect of pooled outcomes was assessed using Grading of Recommendations, Assessment, Development and Evaluation (GRADE). RESULTS: Fifteen studies (n = 11 randomized trials, n = 4 non-randomized trials) of 18 interventions (N = 1898 total participants; 100 % ≥18 years of age) were included. Ten studies examined THC (70 % synthetic), two synthetic cannabidiol with or without THC, and six whole-plant extracts. No clinically significant effects of medicinal cannabis were found on primary outcomes. The likelihood of anxiety events increased with higher-dose synthetic THC compared with a lower dose (OR: 2.0; 95 % CI: 1.4, 2.9; p < 0.001; Confidence: very low). Medicinal cannabis (THC, cannabidiol, and whole-plant extract) increased the likelihood of improved appetite (OR: 12.3; 95 % CI: 3.5, 45.5; p < 0.001; n = 3 interventions; Confidence: moderate) and reduced severity of appetite loss (SMD: -0.4; 95 % CI: -0.8, -0.1; p = 0.009; Confidence: very low). There was very low confidence that higher doses of synthetic THC increased the likelihood of any adverse event (OR: 0.5; 95 % CI: 0.3, 0.7; p < 0.001). Medicinal cannabis had no effect on emotional functioning, mood changes, confusion, disorientation, quality of life, and gastrointestinal symptoms. Confidence in findings was limited by some studies having high or unclear risk of bias and imprecise pooled estimates. CONCLUSIONS: There was insufficient evidence to determine the efficacy and safety of medicinal cannabis as a therapeutic intervention for depression, anxiety, or stress in people with active cancer. Further research should explore whether medicinal cannabis might improve and maintain appetite and if high-dose synthetic THC might increase the incidence of side-effects, including anxiety. To inform clinical practice, well-powered and rigorously designed trials are warranted that evaluate the effects of medicinal cannabis prescribed to target anxiety, depression, and stress.

RESUMO

BACKGROUND: There is substantial interest in the role of ginger as an adjuvant therapy for chemotherapy-induced nausea and vomiting (CINV). However, available evidence lacks robust methodology. OBJECTIVE: To assess the effect of adjuvant ginger compared with placebo on chemotherapy-induced nausea-related quality of life (QoL) and CINV-related outcomes. DESIGN: A parallel, double-blind, placebo-controlled randomized trial with 1:1 allocation was conducted. PARTICIPANTS/SETTING: One hundred three chemotherapy-naïve adults scheduled to receive moderately to highly emetogenic chemotherapy at two hospitals in Australia were enrolled and analyzed. INTERVENTION: Four standardized ginger capsules (totaling 84 mg/day active gingerols/shogaols), or placebo, were administered commencing the day of chemotherapy and continuing for 5 days for chemotherapy cycles 1 through 3. MAIN OUTCOME MEASURES: The primary outcome was chemotherapy-induced nausea-related QoL. Secondary outcomes were vomiting- and CINV-related QoL; anticipatory, acute, and delayed nausea and vomiting; fatigue; nutritional status; depression and anxiety; health-related QoL; and adverse events. STATISTICAL ANALYSES PERFORMED: Intention-to-treat analysis was performed. Mixed analysis of variance with repeated measures determined differences between groups. The null hypothesis was no difference between groups. After applying a Bonferroni multiple testing correction, evidence against the null hypothesis was considered at P= 0.003. RESULTS: One hundred three participants (ginger: n = 52; placebo: n = 51) were enrolled and analyzed. There was clinically relevant evidence against the null hypothesis, favoring ginger, in change scores for nausea-related QoL (F[df] = 9.34[1,101]; P = 0.003; partial η2 = 0.09), overall CINV-related QoL (F[df] = 12.26[1,101]; P < 0.001; partial η2 = 0.11), delayed nausea severity (F[df] = 9.46[1,101]; P = 0.003; partial η2 = 0.09), and fatigue (F[df] = 10.11[1,101]; P = 0.002; partial η2 = 0.09). There was a clinically meaningful lower incidence of delayed nausea and vomiting in the ginger group at Cycle 2 (53% vs 75%; P = 0.020 and 4% vs 27%; P = 0.001, respectively) and Cycle 3 (49% vs 79%; P = 0.002 and 2% vs 23%; P = 0.001, respectively). There was a clinically meaningful lower incidence of malnutrition in the ginger group at Cycle 3 (18% vs. 41%; P = 0.032) and in change scores for Patient-Generated Subjective Global Assessment (F[df)] = 4.32[1,100]; P = 0.040; partial η2 = 0.04). Change scores between groups favored ginger for vomiting-related QoL and number of vomiting episodes; however, findings were not clinically meaningful. There was no effect of ginger on anticipatory or acute CINV, health-related QoL, anxiety, or depression. No serious adverse events were reported. CONCLUSIONS: Ginger supplementation was a safe adjuvant to antiemetic medications for CINV that enhanced QoL during chemotherapy treatment. Future trials are needed to examine dose-dependent responses to verify optimal dosing regimens.

RESUMO

BACKGROUND: Despite compositional alterations in gastrointestinal microbiota being purported to underpin some of the therapeutic effects of ginger, the effect of a standardized ginger supplement on gut microbiota has not been tested in humans. OBJECTIVES: To determine the effect of a standardized ginger (Zingiber officinale) root powder, compared to placebo, on gastrointestinal bacteria and associated outcomes in healthy adults. METHODS: A randomized double-blind placebo-controlled trial allocated participants aged 18 to 30 y to ginger or microcrystalline cellulose (MCC) placebo. The intervention comprised 1.2 g/d of ginger (4 capsules per day totaling 84 mg/d of active gingerols/shogaols) for 14 d following a 1-wk run-in period. Primary outcomes were gastrointestinal community composition, alpha and beta diversity, and differential abundance, measured using 16S rRNA gene sequencing of fecal samples. Secondary outcomes were gastrointestinal symptoms, bowel function, depression, anxiety, stress, fatigue, quality of life, and adverse events. RESULTS: Fifty-one participants were enrolled and analyzed (71% female; mean age 25 ± 3 y; ginger: n = 29, placebo: n = 22). There was a greater increase in relative abundance of phylum, Actinobacteria, observed following ginger supplementation compared to placebo (U: 145.0; z: -2.1; P = 0.033). Ginger was associated with a greater abundance of the genera Parabacteroides, Bacillus, Ruminococcaceae incertae sedis, unclassified Bacilli, families Defluviitaleaceae, Morganellaceae, and Bacillaceae as well as lower abundance of the genus Blautia and family Sphingomonadaceae (P < 0.05). An improvement in indigestion symptoms was observed with ginger supplementation (U: 196.0; z: -2.4; P = 0.015). No differences between ginger and placebo groups were found for alpha and beta diversity or other secondary outcomes. No moderate or severe adverse events were reported. CONCLUSIONS: Supplementation with ginger root powder was safe and altered aspects of gastrointestinal bacteria composition; however, it did not change alpha- or beta diversity, bowel function, gastrointestinal symptoms, mood, or quality of life in healthy adults. These results provide further understanding regarding the mechanisms of action of ginger supplementation. This trial was registered in the Australia New Zealand Clinical Trials Registry as ACTRN12620000302954p and the Therapeutic Goods Administration as CT-2020-CTN-00380-1.

RESUMO

Ginger (Zingiber officinale) has been investigated for its potentially therapeutic effect on a range of chronic conditions and symptoms in humans. However, a simplified and easily understandable examination of the mechanisms behind these effects is lacking and, in turn, hinders interpretation and translation to practice, and contributes to overall clinical heterogeneity confounding the results. Therefore, drawing on data from nonhuman trials, the objective for this narrative review was to comprehensively describe the current knowledge on the proposed mechanisms of action of ginger on conferring therapeutic health effects in humans. Mechanistic studies support the findings from human clinical trials that ginger may assist in improving symptoms and biomarkers of pain, metabolic chronic disease, and gastrointestinal conditions. Bioactive ginger compounds reduce inflammation, which contributes to pain; promote vasodilation, which lowers blood pressure; obstruct cholesterol production, which regulates blood lipid profile; translocate glucose transporter type 4 molecules to plasma membranes to assist in glycemic control; stimulate fatty acid breakdown to aid weight management; and inhibit serotonin, muscarinic, and histaminergic receptor activation to reduce nausea and vomiting. Additional human trials are required to confirm the antimicrobial, neuroprotective, antineoplastic, and liver- and kidney-protecting effects of ginger. Interpretation of the mechanisms of action will help clinicians and researchers better understand how and for whom ginger may render therapeutic effects and highlight priority areas for future research.

RESUMO

BACKGROUND: The present study aimed to investigate health service nutrition practices of sites providing care to patients undergoing surgery for upper gastrointestinal cancer within Australia, including the provision of perioperative nutrition support services and outpatient clinics, as well as the use of evidence-based nutrition care pathways/protocols. Secondary aims were to investigate associations between the use of a nutrition care pathway/protocol and patient outcomes. METHODS: Principal investigator dietitians for the sites (n = 27) participating in the NOURISH point prevalence study participated in a purpose-built site-specific survey regarding perioperative nutrition practices and protocols. Data from the 200 patients who participated in the study (including malnutrition prevalence, preoperative weight loss and receipt of dietetics intervention, intraoperative feeding tube insertions, provision of nutrition support day 1 post surgery, length of stay, and complications) were investigated using multivariate analysis to determine associations with the sites' use of a nutrition care pathway/protocol. RESULTS: The majority of sites (>92%) reported having dietetics services available in chemotherapy/radiotherapy. Eighty-five percent of sites reported having some form of outpatient clinic service; however, a routine service was only available at 26% of sites preoperatively and 37% postoperatively. Most preoperative services were embedded into surgical/oncology clinics (70%); however, this was reported for only 44% of postoperative clinics. Only 44% had a nutrition care pathway/protocol in place. The use of a nutrition care pathway/protocol was associated with lower rates of malnutrition, as well as higher rates of preoperative dietetics intervention, intraoperative feeding tube insertions, and European Society of Clinical Nutrition and Metabolism (ESPEN) guideline compliant care day 1 post surgery. CONCLUSIONS: The results of the present study demonstrate varied perioperative outpatient nutrition services in this high-risk patient group. The use of nutrition care pathways and protocols was associated with improved patient outcomes.

RESUMO

BACKGROUND: Bariatric weight-loss surgery rates are increasing internationally. Endoscopic sleeve gastroplasty (ESG) is a novel, minimally invasive endoscopic procedure thought to mimic some of the effects of a more common surgery, laparoscopic sleeve gastrectomy (LSG). Patient factors affecting procedural choice are unexplored. OBJECTIVE: This formative study aimed to determine the preoperative and early postoperative characteristics of adults matched for age, sex, and BMI who chose ESG versus LSG. METHODS: This prospective cohort study recruited ESG and matched LSG adults in Australia. Preoperative outcomes were medical history, glycemic biomarkers, blood lipids, liver function enzymes, albumin, blood pressure, hepatic steatosis index, the Gastrointestinal Symptom Rating Scale, the Impact of Weight on Quality of Life-Lite questionnaire, and body composition via dual-energy x-ray absorptiometry. Adverse events were recorded preoperatively and up to 2 weeks postoperatively. SPSS was used to test if there were differences between cohorts by comparing means or mean ranks, and binary regression was used to understand how characteristics might predict procedure choice. RESULTS: A total of 50 (including 25 ESG and 25 LSG) patients were recruited, who were primarily White (45/50, 90%) and female (41/50, 82%) with a mean age of 41.7 (SD 9.4) years. Participants had a mean of 4.0 (SD 2.2) active comorbid conditions, with the most common being nonalcoholic fatty liver disease (38/50, 76%), back pain (32/50, 64%), anxiety or depression (24/50, 48%), and joint pain (23/50, 46%). The LSG cohort had higher hemoglobin A1c (5.3%, SD 0.2%) than the ESG cohort (5%, SD 0.2%; P=.008). There was a 2.4 kg/m2 difference in median BMI (P=.03) between the groups, but fat and fat-free mass had no meaningful differences. Comparing the LSG and ESG groups showed that the LSG group had lower total quality of life (49.5%, SD 10.6% vs 56.6%, SD 12.7%; P=.045), lower weight-related self-esteem (10.7%, IQR 3.6%-25% vs 25%, IQR 17.9%-39.3%; P=.02), and worse abdominal pain (38.9%, IQR 33.3%-50% vs 53.9%, SD 14.2%, P=.01). For every percent improvement in weight-related self-esteem, the odds for selecting ESG increased by 4.4% (95% CI 1.004-1.085; P=.03). For every percent worsening in hunger pain, the odds for selecting ESG decreased by 3.3% (95% CI 0.944-0.990; P=.004). CONCLUSIONS: There was very little evidence that Australian adults who chose an endoscopic versus surgical sleeve had different rates of comorbidities, body fat percentage, or weight-related quality of life. There was evidence against the test hypothesis, that is, there was evidence suggesting that lower self-esteem predicted choosing a more invasive sleeve (ie, LSG rather than ESG).

RESUMO

BACKGROUND: Emerging evidence supports the health benefits of ginger for a range of conditions and symptoms; however, there is a lack of synthesis of literature to determine which health indications are supported by quality evidence. OBJECTIVES: In this umbrella review of systematic reviews we aimed to determine the therapeutic effects and safety of any type of ginger from the Zingiber family administered in oral form compared with any comparator or baseline measures on any health and well-being outcome in humans. METHODS: Five databases were searched from inception to April 2021. Review selection and quality were assessed in duplicate using the Assessment of Multiple Systematic Reviews-2 (AMSTAR-2) checklist and the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) method, with results presented in narrative form. RESULTS: Twenty-four systematic reviews were included with 3% overlap of primary studies. The strongest evidence was found for the antiemetic effects of ginger in pregnant women (effect size: large; GRADE: high), analgesic effects for osteoarthritis (effect size: small; GRADE: high), and glycemic control (effect size: none to very large; GRADE: very low to moderate). Ginger also had a statistically significant positive effect on blood pressure, weight management, dysmenorrhea, postoperative nausea, and chemotherapy-induced vomiting (effect size: moderate to large; GRADE: low to moderate) as well as blood lipid profile (effect size: small; GRADE: very low) and anti-inflammatory and antioxidant biomarkers (effect size: unclear; GRADE: very low to moderate). There was substantial heterogeneity and poor reporting of interventions; however, dosage of 0.5-3 g/d in capsule form administered for up to 3 mo was consistently reported as effective. CONCLUSIONS: Dietary consumption of ginger appears safe and may exert beneficial effects on human health and well-being, with greatest confidence in antiemetic effects in pregnant women, analgesic effects in osteoarthritis, and glycemic control. Future randomized controlled and dose-dependent trials with adequate sample sizes and standardized ginger products are warranted to better inform and standardize routine clinical prescription.

RESUMO

BACKGROUND: The laparoscopic sleeve gastrectomy (LSG) and the incisionless endoscopic sleeve gastroplasty (ESG) weight loss procedures require further investigation of their efficacy, safety and patient-centered outcomes in the Australian setting. METHODS: The aim was to examine the 6- and 12-month weight loss efficacy, safety, and weight-related quality of life (QoL) of adults with obesity who received the ESG or LSG bariatric procedure with 12+ months of adjuvant multidisciplinary pre- and postprocedural support. Data were from a two-arm prospective cohort study that followed patients from baseline to 12-months postprocedure from a medical center in Queensland. Percent excess weight loss (%EWL) was the primary outcome. Secondary outcomes were body composition (fat mass, fat-free mass, android:gynoid ratio, bone mineral content) via dual energy X-ray absorptiometry, weight-related QoL, lipid, glycemic, and hepatic biochemistry, and adverse events. RESULTS: 16 ESG (19% attrition; 81.2% female; aged:41.4 (SD: 10.4) years; BMI: 35.5 (SD: 5.2) kg/m2) and 45 LSG (9% attrition; 84.4% female; aged:40.4 (SD: 9.0) years; BMI: 40.7 (SD: 5.6) kg/m2) participants were recruited. At 12-months postprocedure, ESG %EWL was 57% (SD: 32%; p < 0.01) and LSG %EWL was 79% (SD: 24%; p < 0.001). ESG and LSG cohorts improved QoL (19.8% in ESG [p > 0.05]; 48.1% in LSG [p < 0.05]), liver function (AST: - 4.4 U/L in ESG [p < 0.05]; - 2.7 U/L in LSG [p < 0.05]), HbA1c (- 0.5% in ESG [p < 0.05]; - 0.1% in LSG [p < 0.05]) and triglycerides (- 0.6 mmol/L in ESG [p > 0.05]; - 0.4 mmol/L in LSG [P < 0.05]) at 12-months. Both cohorts reduced fat mass (p < 0.05). The ESG maintained but LSG decreased fat-free mass at 6-months (p < 0.05); and both cohorts lost fat-free mass at 12-months (p < 0.05). There were no adverse events directly related to the procedure. The ESG reported 25% mild-moderate adverse events possibly related to the procedure, and the LSG reported 27% mild-severe adverse events possibly related to the procedure. CONCLUSIONS: In this setting, the ESG and LSG were safe and effective weight loss treatments for obese adults alongside multidisciplinary support. Patients who elected the ESG maintained fat-free mass at 6-months but both cohorts lost fat-free mass at 12-months postprocedure. Patients who elected the LSG had large and significant improvements to weight-related quality of life. Further well-powered studies are required to confirm these findings. TRIAL REGISTRATION: This study was registered prospectively at the Australia New Zealand Clinical Trials Registry on 06/03/2018, Registration Number ACTRN12618000337279 .

RESUMO

BACKGROUND: Postoperative nutrition support is an essential component of management in upper gastrointestinal (UGI) cancer resection, however there is limited knowledge of current clinical practice. This study aimed to describe the postoperative nutrition support received by patients undergoing UGI cancer resections, assess adherence with ESPEN surgical guideline recommendations, and to investigate differences between oesophageal, gastric and pancreatic surgeries. The secondary aim was to explore the association of adherence with ESPEN guidelines and provision of nutrition support, with surgical complications and length of stay (LOS). METHODS: The NOURISH point prevalence study was conducted between September 2019-June 2020 across 27 Australian tertiary centres. Malnutrition was diagnosed using subjective global assessment. Data on postoperative diet codes, prescription of nutrition support (oral (ONS), enteral (EN), parenteral (PN)) and nutritional adequacy were collected by dietitians for the first 10 days of admission. Fisher's exact test was used to determine differences in nutritional management and adherence to ESPEN guidelines between surgery types. Multivariate regression analysed associations with surgical outcomes. RESULTS: Two-hundred participants were included (42% pancreatic, 33% oesophageal, 25% gastric surgery). Overall, only 34.9% (n = 53) met the guideline recommendations that were applicable to them. Early oral intake of fluids or solids (within 24 h post surgery) was initiated for 23.5% (n = 47), whilst ONS/EN/PN was initiated for 49.5% (n = 99). Only 25% of pancreatic surgeries had nutrition support initiated on the first postoperative day compared to 86.4% of oesophageal and 42.0% of gastric surgeries (p < 0.001). In those who were 'nil by mouth', EN/PN were commenced within 24 h for 51.0% (n = 78), with 18.5% and 45.2% for pancreatic and gastric surgeries compared to 86.0% in oesophageal surgeries (p < 0.001). In malnourished patients, 35.7% (n = 30) commenced EN within 24 h, with 11.1% and 31.8% for pancreatic and gastric compared to 73.1% in oesophageal surgeries (p < 0.001). For patients meeting <60% energy/protein requirements for ≥7 days, only 14.8% (n = 9) received EN/PN, with 2.5% and 16.7% of pancreatic and gastric compared to 75.0% of oesophageal surgeries (p < 0.001). The number of days spent 'nil by mouth' or 'clear fluids' without EN/PN, as well as number of days with <60% estimated requirements met were independently associated with increased LOS and complications. CONCLUSIONS: Overall, there was poor adherence to the majority of assessed ESPEN guidelines, and care for patients undergoing pancreatic and gastric surgeries was less compliant than oesophagectomy. Poor nutritional adequacy was associated with increased LOS and complications. There is a clear need for knowledge translation and implementation studies to increase adherence to evidence-based recommendations in the Australian setting supported by an understanding of barriers and enablers to optimal postoperative nutrition management.

RESUMO

BACKGROUND: Identification and treatment of malnutrition are essential in upper gastrointestinal (UGI) cancer. However, there is limited understanding of the nutritional status of UGI cancer patients at the time of curative surgery. This prospective point prevalence study involving 27 Australian tertiary hospitals investigated nutritional status at the time of curative UGI cancer resection, as well as presence of preoperative nutrition impact symptoms, and associations with length of stay (LOS) and surgical complications. METHODS: Subjective global assessment, hand grip strength (HGS) and weight were performed within 7 days of admission. Data on preoperative weight changes, nutrition impact symptoms, and dietary intake were collected using a purpose-built data collection tool. Surgical LOS and complications were also recorded. Multivariate regression models were developed for nutritional status, unintentional weight loss, LOS and complications. RESULTS: This study included 200 patients undergoing oesophageal, gastric and pancreatic surgery. Malnutrition prevalence was 42% (95% confidence interval (CI) 35%, 49%), 49% lost ≥5% weight in 6 months, and 47% of those who completed HGS assessment had low muscle strength with no differences between surgical procedures (p = 0.864, p = 0.943, p = 0.075, respectively). The overall prevalence of reporting at least one preoperative nutrition impact symptom was 55%, with poor appetite (37%) and early satiety (23%) the most frequently reported. Age (odds ratio (OR) 4.1, 95% CI 1.5, 11.5, p = 0.008), unintentional weight loss of ≥5% in 6 months (OR 28.7, 95% CI 10.5, 78.6, p < 0.001), vomiting (OR 17.1, 95% CI 1.4, 207.8, 0.025), reduced food intake lasting 2-4 weeks (OR 7.4, 95% CI 1.3, 43.5, p = 0.026) and ≥1 month (OR 7.7, 95% CI 2.7, 22.0, p < 0.001) were independently associated with preoperative malnutrition. Factors independently associated with unintentional weight loss were poor appetite (OR 3.7, 95% CI 1.6, 8.4, p = 0.002) and degree of solid food reduction of <75% (OR 3.3, 95% CI 1.2, 9.2, p = 0.02) and <50% (OR 4.9, 95% CI 1.5, 15.6, p = 0.008) of usual intake. Malnutrition (regression coefficient 3.6, 95% CI 0.1, 7.2, p = 0.048) and unintentional weight loss (regression coefficient 4.1, 95% CI 0.5, 7.6, p = 0.026) were independently associated with LOS, but no associations were found for complications. CONCLUSIONS: Despite increasing recognition of the importance of preoperative nutritional intervention, a high proportion of patients present with malnutrition or clinically significant weight loss, which are associated with increased LOS. Factors associated with malnutrition and weight loss should be incorporated into routine preoperative screening. Further investigation is required of current practice for dietetics interventions received prior to UGI surgery and if this mitigates the impact on clinical outcomes.

RESUMO

AIM: This study assessed the responsiveness and convergent validity of two preference-based measures; the newly developed cancer-specific EORTC Quality of Life Utility Measure-Core 10 dimensions (QLU-C10D) relative to the generic three-level version of the EuroQol 5 dimensions (EQ-5D-3L) in evaluating short-term health related quality of life (HRQoL) outcomes after esophagectomy. METHODS: Participants were enrolled in a multicentre randomised controlled trial to determine the impact of preoperative and postoperative immunonutrition versus standard nutrition in patients with esophageal cancer. HRQoL was assessed seven days before and 42 days after esophagectomy. Standardized Response Mean and Effect Size were calculated to assess responsiveness. Ceiling effects for each dimension were calculated as the proportion of the best level responses for that dimension at follow-up/post-operatively. Convergent validity was assessed using Spearman's correlation and the level of agreement was explored using Bland-Altman plots. RESULTS: Data from 164 respondents (mean age: 63 years, 81% male) were analysed. HRQoL significantly reduced on both measures with large effect sizes (> 0.80), and a greater mean difference (0.29 compared to 0.16) on QLU-C10D. Both measures had ceiling effects (> 15%) on all dimensions at baseline. Following esophagectomy, ceiling effects were observed with self-care (86%), mobility (67%), anxiety/depression (55%) and pain/discomfort (19%) dimensions on EQ-5D-3L. For QLU-C10D ceiling effects were observed with emotional function (53%), physical function (16%), nausea (35%), sleep (31%), bowel problems (21%) and pain (20%). A strong correlation (r = 0.71) was observed between EQ-5D-3L anxiety and QLU-C10D emotional function dimensions. Good agreement (3.7% observations outside the limits of agreement) was observed between the utility scores. CONCLUSION: The QLU-C10D is comparable to the more widely applied generic EQ-5D-3L, however, QLU-C10D was more sensitive to short-term utility changes following esophagectomy. Cognisant of requirements by policy makers to apply generic utility measures in cost effectiveness studies, the disease-specific QLU-C10D should be used alongside the generic measures like EQ-5D-3L. TRIAL REGISTRATION: The trial was registered with the Australian New Zealand Clinical Trial Registry (ACTRN12611000178943) on the 15th of February 2011.

RESUMO

BACKGROUND: Preoperative nutrition intervention is recommended prior to upper gastrointestinal (UGI) cancer resection; however, there is limited understanding of interventions received in current clinical practice. This study investigated type and frequency of preoperative dietetics intervention and nutrition support received and clinical and demographic factors associated with receipt of intervention. Associations between intervention and preoperative weight loss, surgical length of stay (LOS), and complications were also investigated. METHODS: The NOURISH Point Prevalence Study was conducted between September 2019 and May 2020 across 27 Australian tertiary centres. Subjective global assessment and weight were performed within 7 days of admission. Patients reported on preoperative dietetics and nutrition intervention, and surgical LOS and complications were recorded. RESULTS: Two-hundred patients participated (59% male, mean (standard deviation) age 67 (10)). Sixty percent had seen a dietitian preoperatively, whilst 50% were receiving nutrition support (92% oral nutrition support (ONS)). Patients undergoing pancreatic surgery were less likely to receive dietetics intervention and nutrition support than oesophageal or gastric surgeries (p < 0.001 and p = 0.029, respectively). Neoadjuvant therapy (p = 0.003) and malnutrition (p = 0.046) remained independently associated with receiving dietetics intervention; however, 31.3% of malnourished patients had not seen a dietitian. Patients who received ≥3 dietetics appointments had lower mean (SD) percentage weight loss at the 1-month preoperative timeframe compared with patients who received 0-2 appointments (1.2 (2.0) vs. 3.1 (3.3), p = 0.001). Patients who received ONS for >2 weeks had lower mean (SD) percentage weight loss than those who did not (1.2 (1.8) vs. 2.9 (3.4), p = 0.001). In malnourished patients, total dietetics appointments ≥3 was independently associated with reduced surgical complications (odds ratio 0.2, 95% confidence interval (CI) 0.1, 0.9, p = 0.04), and ONS >2 weeks was associated with reduced LOS (regression coefficient -7.3, 95% CI -14.3, -0.3, p = 0.04). CONCLUSIONS: Despite recommendations, there are low rates of preoperative dietetics consultation and nutrition support in this population, which are associated with increased preoperative weight loss and risk of increased LOS and complications in malnourished patients. The results of this study provide insights into evidence-practice gaps for improvement and data to support further research regarding optimal methods of preoperative nutrition support.

RESUMO

BACKGROUND & AIMS: Omega-3 polyunsaturated fatty acid (PUFA) supplementation has been proposed as a potential therapy for cancer-related malnutrition, which affects up to 70% of patients with cancer. The aim of this systematic review and meta-analysis was to examine the effects of oral omega-3 PUFA supplementation on muscle maintenance, quality of life, body weight and treatment-related toxicities in patients with cancer. METHODS: Randomised controlled trials in patients with cancer aged ≥18 years were retrieved from 5 electronic databases: MEDLINE (via PubMed), EMBASE, CENTRAL, CINAHL (via EBSCOhost), and Web of Science, from database inception until 31st of December 2019. The quality of included studies was assessed using the Cochrane risk of bias tool. Trials supplementing ≥600 mg/d omega-3 PUFA (oral capsules, pure fish oil or oral nutritional supplements) compared with a control intervention for ≥3 weeks were included. Meta-analyses were performed in RevMan to determine the mean differences (MD) in muscle mass, quality of life and body weight, and odds ratio (OR) for the incidence of treatment-related toxicities between omega-3 PUFA and control groups with 95% confidence intervals (CI) and I2 for heterogeneity. RESULTS: We included 31 publications in patients with various types of cancers and degrees of malnutrition. The Cochrane risk of bias tool graded most trials as 'unclear' or 'high' risk of bias. Meta-analyses showed no significant difference between omega-3 PUFA supplements and control intervention on muscle mass, quality of life and body weight. Oral omega-3 PUFA supplements reduced the likelihood of developing chemotherapy-induced peripheral neuropathy (OR: 0.20; 95% CI: 0.10-0.40; p < 0.001; I2 = 0%). CONCLUSION: This systematic review and meta-analysis indicates that oral omega-3 PUFA supplementation does not improve muscle maintenance, quality of life or body weight in patients with cancer, but may reduce the incidence of chemotherapy-induced peripheral neuropathy. Well-designed large-scale randomised controlled trials in homogenous patient cohorts are required to confirm these findings.

RESUMO

BACKGROUND: This practical guideline is based on the current scientific ESPEN guidelines on nutrition in cancer patients. METHODS: ESPEN guidelines have been shortened and transformed into flow charts for easier use in clinical practice. The practical guideline is dedicated to all professionals including physicians, dieticians, nutritionists and nurses working with patients with cancer. RESULTS: A total of 43 recommendations are presented with short commentaries for the nutritional and metabolic management of patients with neoplastic diseases. The disease-related recommendations are preceded by general recommendations on the diagnostics of nutritional status in cancer patients. CONCLUSION: This practical guideline gives guidance to health care providers involved in the management of cancer patients to offer optimal nutritional care.

RESUMO

BACKGROUND AND PURPOSE: Minimal evidence regarding the safety and efficacy of complementary and alternative medicine (CAM) use during chemotherapy is accompanied with a high prevalence of use and nondisclosure to health professionals. This study aimed to explore patients' perspectives, experiences, support needs, and sources of information regarding CAM use during chemotherapy. MATERIALS AND METHODS: Semi-structured interviews with ten adult participants who recently completed chemotherapy treatment at a large hospital in Australia were transcribed verbatim. Three investigators thematically analysed the interviews. RESULTS: These participants receiving chemotherapy valued CAMs as a natural complement to chemotherapy to improve wellbeing, with their use most strongly influenced by past experiences rather than expert advice. CONCLUSION: Health professionals would benefit from education on how to best inform patients of the potential risks, harms and lack of efficacy for CAM use during chemotherapy in a way that does not lead to patient non-disclosure of CAM use.

RESUMO

BACKGROUND: Patients undergoing (chemo) radiotherapy for oropharyngeal squamous cell carcinoma (OPSCC) are at high risk of malnutrition during and after treatment. Malnutrition can lead to poor tolerance to treatment, treatment interruptions, poor quality of life (QOL) and potentially reduced survival rate. Human papillomavirus (HPV) is now known as the major cause of OPSCC. However, research regarding its effect on nutritional outcomes is limited. The aim of this study was to examine the relationship between HPV status and nutritional outcomes, including malnutrition and weight loss during and after patients' (chemo) radiotherapy treatment for OPSCC. Methods: This was a longitudinal cohort study comparing the nutritional outcomes of HPV-positive and negative OPSCC patients undergoing (chemo) radiotherapy. The primary outcome was nutritional status as measured using the Patient Generated-Subjective Global Assessment (PG-SGA). Secondary outcomes included loss of weight, depression, QOL and adverse events. Results: Although HPV-positive were less likely to be malnourished according to PG-SGA at the beginning of treatment, we found that the difference between malnutrition rates in response to treatment was not significantly different over the course of radiotherapy and 3 months post treatment. HPV-positive participants had significantly higher odds of experiencing >10% weight loss at three months post-treatment than HPV-negative participants (OR = 49.68, 95% CI (2.7, 912.86) p ≤ 0.01). Conclusions: The nutritional status of HPV positive and negative patients were both negatively affected by treatment and require similarly intense nutritional intervention. In acute recovery, HPV positive patients may require more intense intervention. At 3- months post treatment, both groups still showed nutritional symptoms that require nutritional intervention so ongoing nutritional support is essential.

RESUMO

BACKGROUND: Poor adherence to intensive care unit (ICU) guidelines is common, leading to suboptimal nutritional care. This study determined current ward-based nutrition care practices in the Indian ICU setting, comparing them to international best-practice guidelines and provided patient demographic, clinical and nutritional information to serve as baseline data for future benchmarking. METHODS: This multi-site cross-sectional retrospective study analysed data collected from nutritionDay worldwide audits (2012-2016) across ICUs from a chain of urban private hospitals in India. Additional guideline-specific data were collected through questionnaires and phone interviews with the Head of Dietetics Departments in the participating hospitals. RESULTS: Overall, 10 ICUs and 457 participants were included. It was common practice to use modified versions of the Mini Nutritional Assessment-Short Form (MNA-SF) and Subjective Global Assessment (SGA) for nutrition screening and assessment. Nearly half the participants (n = 222, 49%) received nutrition orally. A majority of the remaining participants received enteral nutrition (n = 163, 36%) or no nutrition (n = 60, 13%) at the time of data collection. The calories prescribed for most participants were between 1500 and 1999 kilocalories per day (n = 207, 45%), with no nutrition planned for 115 (25%) participants. Three-quarters (n = 129, 74%) of participants on EN received the planned calories, while 24% (n = 42) were given less than planned. CONCLUSION: Overall, most participants received the calories planned for enteral nutrition. The use of modified screening and assessment tools and suboptimal delivery of EN remains a global problem for critical care, possibly requiring a more pragmatic approach to nutritional therapy.

RESUMO

This position statement describes the recommendations of the Clinical Oncology Society of Australia (COSA) regarding management of cancer-related malnutrition and sarcopenia. A multidisciplinary working group completed a review of the literature, focused on evidence-based guidelines, systematic reviews and meta-analyses, to develop recommendations for the position statement. National consultation of the position statement content was undertaken through COSA members. All people with cancer should be screened for malnutrition and sarcopenia in all health settings at diagnosis and as the clinical situation changes throughout treatment and recovery. People identified as "at risk" of malnutrition or with a high-risk cancer diagnosis or treatment plan should have a comprehensive nutrition assessment; people identified as "at risk" of sarcopenia should have a comprehensive evaluation of muscle status using a combination of assessments for muscle mass, muscle strength and function. All people with cancer-related malnutrition and sarcopenia should have access to the core components of treatment, including medical nutrition therapy, targeted exercise prescription and physical and psychological symptom management. Treatment for cancer-related malnutrition and sarcopenia should be individualised, in collaboration with the multidisciplinary team (MDT), and tailored to meet needs at each stage of cancer treatment. Health services should ensure a broad range of health care professionals across the MDT have the skills and confidence to recognise malnutrition and sarcopenia to facilitate timely referrals and treatment. The position statement is expected to provide guidance at a national level to improve the multidisciplinary management of cancer-related malnutrition and sarcopenia.

RESUMO

INTRODUCTION: Nutritional intervention and prevention of malnutrition is significantly important for patients with upper gastrointestinal oesophageal, pancreatic and gastric cancer. However, there is limited information regarding nutritional status, and perioperative nutritional interventions that patients receive when undergoing curative surgery. METHODS AND ANALYSIS: Patients diagnosed with upper gastrointestinal cancer, planned for curative intent resection across 27 Australian hospitals will be eligible to participate in this point prevalence study. The primary aim is to determine the prevalence of malnutrition in patients with upper gastrointestinal cancer at the time of surgery using subjective global assessment. Secondary aims are to determine the type and frequency of perioperative nutritional intervention received, the prevalence of clinically important weight loss and low muscle strength, and to investigate associations between the use of an evidence-based nutrition care pathway or protocol for the nutritional management of upper gastrointestinal surgical oncology patients and malnutrition prevalence. Data collection will be completed using a purpose-built data collection tool. ETHICS AND DISSEMINATION: Ethical approval was granted in May 2019 (LNR/51107/PMCC-2019). The design and reporting of this study comply with the Strengthening the Reporting of Observational Studies in Epidemiology checklist for reporting of observational cohort studies. Findings will be published in peer-reviewed scholarly journals and presented at relevant conferences. Results will assist in defining priority areas for research to improve patient outcomes.

RESUMO

BACKGROUND: Malnutrition is highly prevalent in patients with Upper Gastrointestinal (UGI) cancer and is associated with poor outcomes. However, there are no evidence-based guidelines for nutrition support specific to UGI cancer surgery. METHODS: Databases including MEDLINE, PUBMED, CINAHL, Web of Science, Cochrane Central and Clinicaltrials.gov were systematically searched. Abstracts of studies investigating the effect of preoperative nutrition support on nutritional status, functional status, body composition, quality of life and treatment outcomes in adult patients undergoing oesophageal, gastric or pancreatic cancer resection were identified. Screening of studies, quality assessment using the Downs and Black checklist, data extraction, and appraisal of evidence using GRADE were performed by two reviewers. Due to heterogeneity of the studies, results were synthesised narratively. The protocol was registered in PROSPERO (CRD42018111930). RESULTS: Nine studies with a total of 442 oesophageal and 418 gastric patients were included. Individualised dietary counselling, and enteral feeding in neoadjuvant therapy for oesophageal cancer demonstrated positive effects for weight maintenance and surgical complications, however the GRADE evidence quality was very low. Preoperative nutrition support in gastric cancer decreased the incidence of surgical site infections, length of stay and hospital costs, but GRADE assessment was unable to be completed due to only one study reporting on each outcome measure. CONCLUSIONS: This review demonstrates the lack of strong evidence to determine the most optimal methods of nutrition support prior to UGI cancer resection. Current surgical oncology guidelines should be utilised until further research from high quality trials enable the development of specific clinical practice guidelines.
