RESUMO
Soft tissue sarcomas are rare malignant tumors. Traditionally, treatment is guided by patient and tumor characteristics. Data on the influence of patient characteristics, particularly nutritional status, on clinical outcomes are scarce. Body composition and its changes during treatment play an essential role in predicting toxicity, clinical outcomes, and mortality. This analysis aimed to investigate the relationship between treatment toxicity and body composition. Patients diagnosed with sarcoma who underwent first-line palliative chemotherapy between October 2017 and January 2020 were included. Baseline and follow-up computed tomographic scans at the third lumbar vertebra, available from diagnostic purposes, were analyzed using SliceOmatic software. Treatment toxicity was defined as a composite score of the Common Terminology Criteria for Adverse Events. Nutritional Risk Screening (NRS) 2002 score, psoas muscle thickness to height ratio, and comorbidity showed a significant association with overall toxicity, while skeletal muscle index and age showed a strong trend. In summary, the NRS 2002 tool must be routinely implemented in inpatient and outpatient settings for cancer patients, and nutritional therapy needs to become a fixed component of multimodal cancer treatment. Furthermore, validated standardized procedures for the quantification of muscle mass are needed to individualize and optimize cancer treatment.

PURPOSE OF REVIEW: Malnutrition before and during hematopoietic stem cell transplantation (HSCT) is an independent risk factor for mortality in patients undergoing hematopoietic stem cell transplantation. Yet, optimal use of nutritional support to improve outcomes remains controversial. Our aim was to do an up-to-date literature review regarding nutritional therapy in allogeneic HSCT, the neutropenic diet and the use of immunonutrients. RECENT FINDINGS: Several observational studies find malnutrition to be associated with poor outcome, increased complications and lower overall survival. There are, however, few interventional trials proving the benefits of nutritional therapy in this population compared with no nutritional treatment. Regarding routes of treatment, studies suggested that parenteral nutrition is associated with higher risk for complications compared with enteral nutrition. Whether the use of specific formulas, such as immunonutrition, has a beneficial effect on clinical outcome is not established yet. Strict use of neutropenic diets did not show a reduction in infection risk and clinical outcome, and can no longer be recommended. SUMMARY: Our updated search confirms that malnutrition is a strong negative predictor for outcome, yet optimal use of nutritional interventions to prevent or treat malnutrition remains ill-defined. There is need for larger randomized trials to better address these issues in the future.

INTRODUCTION: In acute myeloid leukemia (AML) patients undergoing allogeneic haematopoietic stem cell transplantation (HSCT), there is uncertainty about the extent of influence nutritional parameters have on clinical outcomes. In this study, we investigated the association between initial body mass index (BMI) and weight loss during HSCT on clinical outcomes in a well-characterised cohort of AML patients. METHODS: We analysed data of the Basel stem-cell transplantation registry ('KMT Kohorte') including all patients with AML undergoing first allogeneic HSCT from January 2003 to January 2014. We used multivariable regression models adjusted for prognostic indicators (European Group for Blood and Marrow Transplantation risk score and cytogenetics). RESULTS: Mortality in the 156 AML patients (46% female, mean age 46 years) over the 10 years of follow-up was 57%. Compared to patients with a baseline BMI (kg/m2) of 20-25, a low BMI <20 was associated with higher long-term mortality (70 vs. 49%, adjusted hazard ratio 1.97, 95% CI 1.04-3.71, p = 0.036). A more pronounced weight loss during HSCT (>7 vs. <2%) was associated with higher risk for bacterial infections (52 vs. 28%, OR 2.8, 95% CI 0.96-8.18, p = 0.059) and fungal infections (48 vs. 23%, OR 3.37, 95% CI 1.11-10.19, p = 0.032), and longer hospital stays (64 vs. 38 days, adjusted mean difference 25.6 days (15.7-35.5), p < 0.001). CONCLUSION: In patients with AML, low initial BMI and more pronounced weight loss during HSCT are strong prognostic indicators associated with lower survival and worse disease outcomes. Intervention research is needed to investigate whether nutritional therapy can reverse these associations.

Recently, a plenitude of novel laboratory tests has become available for physicians to improve the diagnostic and prognostic work up of patients. Yet, as with all tests, laboratory test can be falsely positive or falsely negative and potentially misguide clinicians and caregivers. Shortcomings of pre-analytical factors, test performance as well as an inappropriate ordering of laboratory tests contributes to diagnostic errors and potentially generate unnecessary costs. Laboratory tests should only be ordered, if results have clinical consequences and improve the assessment of the patient. Within this review focusing on the example of the inflammatory biomarker "Procalcitonin" for antibiotic stewardship and the hormonal marker testosterone, we aim to exemplify important draw backs and shortcomings in laboratory tests and the importance of interpretation of these results in the context of the clinical situation.

BACKGROUND: Measurement of skeletal muscle index (SMI) in computed tomography has been suggested to improve the objective assessment of muscle mass. While most studies have focused on lumbar vertebrae, we examine the association of SMI at the thoracic level with nutritional and clinical outcomes and response to nutritional intervention. METHODS: We conducted a secondary analysis of EFFORT, a Swiss-wide, multicenter, randomized trial. We investigated the association of low SMI at the 12th thoracic vertebra (T12) with adverse outcome within 30 days after hospital admission (primary endpoint). RESULTS: 663 of 2028 patients from the EFFORT trial had available CT scans for T12, and 519 among them also had available L3 scans. Mean SMI at T12 was 22.4 ± 5.8 cm2/m2 and 19.6 ± 5.5 cm2/m2 in male and female patients, respectively, and correlated well with nutritional parameters, including nutritional risk based on NRS 2002 (adjusted coefficient -0.63, 95%CI -1.25 to -0.01, p = 0.047), BMI (adjusted coefficient 0.74, 95%CI 0.66 to 0.82, p < 0.001) and handgrip strength (adjusted coefficient 0.15, 95%CI 0.11 to 0.2, p < 0.001). In multivariate regression analyses, low SMI was not a significant predictor for either clinical outcome or for treatment response. Results for SMI measured at L3 were similar, with only little prognostic value. CONCLUSIONS: Within medical patients at risk for malnutrition, SMI at thoracic vertebra provided low prognostic information regarding clinical outcomes and nutritional treatment response.

BACKGROUND & AIM: CT-derived measures of muscle mass may help to identify patients with sarcopenia. We investigated the prognostic significance of CT-derived sarcopenia and muscle attenuation with nutritional markers, clinical outcomes and response to nutritional support in medical in-patients at nutritional risk. METHOD: Within this secondary analysis of the randomized-controlled Effect of early nutritional support on Frailty, Functional Outcomes, and Recovery of malnourished medical inpatients Trial (EFFORT) comparing individualized nutritional support with usual care nutrition in medical inpatients, we investigated associations of CT-based sarcopenia and muscle attenuation at the level L3 with different nutritional and clinical outcomes, and the response to the nutritional intervention. The primary composite endpoint was adverse clinical outcome within 30 days of hospital admission. RESULTS: We included 573 of 2028 EFFORT patients with available CT scans, of which 68.4% met the CT-based definition of sarcopenia and 72.9% had low muscle attenuation. In multivariate analysis, low skeletal muscle index was associated with higher nutritional risk (coefficient per NRS class -0.94 (95%CI -1.87 to -0.01) p = 0.049) and higher risk for adverse clinical outcomes (adjusted odds ratio 1.59 (95% CI 1.06 to 2.38), p = 0.024). Low muscle attenuation was also associated with adverse clinical outcome (adjusted odds ratio 1.67 (95%CI 1.08 to 2.58), p = 0.02). Nutritional support tended to be more effective in reducing mortality in non-sarcopenic patients compared to patients with CT-based sarcopenia (p for interaction 0.058). CONCLUSIONS: Within a population of medical patients at nutritional risk, CT-based sarcopenia and muscle attenuation were associated with several nutritional parameters and predicted adverse clinical outcomes. Information from CT scans, thus may help to better characterize these patients, and may be helpful in guiding therapeutic interventions.

BACKGROUND: Cancer-related malnutrition is a prevalent condition associated with a loss of muscle mass and impaired functional status, leading to immunodeficiency, impaired quality of life and adverse clinical outcomes. Handgrip strength (HGS) is a practical measure to assess muscle strength in individual patients during clinical practice. However, HGS reference values refer to populations of healthy people, and population-specific values, such as those in the population of cancer patients, still need to be defined. METHODS: Within a secondary analysis of a previous randomized controlled nutritional trial focusing on hospitalized cancer patients at risk for malnutrition, we investigated sex-specific HGS values stratified by age and tumor entity. Additionally, we examined the association between HGS and 180-day all-cause mortality. RESULTS: We included data from 628 cancer patients, which were collected from eight hospitals in Switzerland. Depending on the age of patients, HGS varied among female patients from 7 kg to 26 kg and among male patients from 20.5 kg to 44 kg. An incremental decrease in handgrip strength by 10 kg resulted in a 50% increase in 180-day all-cause mortality (odds ratio 1.52 (95%CI 1.19 to 1.94), p = 0.001). CONCLUSION: Our data provide evidence of the prognostic implications of HGS measurement in cancer patients and validate the prognostic value of handgrip strength in regard to long-term mortality. In addition, our results provide expected HGS values in the population of hospitalized malnourished cancer patients, which may allow better interpretation of values in individual patients.

Almost half of inpatients on parenteral nutrition experience hyperglycemia, which increases the risk of complications and mortality. The blood glucose target for hospitalized patients on parenteral nutrition is 7.8 to 10.0 mmol/L (140 to 180 mg/dL). For patients with diabetes, the same parenteral nutrition formulae as for patients without diabetes can be used, as long as blood glucose levels can be adequately controlled using insulin. Insulin can be delivered via the subcutaneous or intravenous route or, alternatively, added to parenteral nutrition admixtures. Combining parenteral with enteral and oral nutrition can improve glycemic control in patients with sufficient endogenous insulin stores. Intravenous insulin infusion is the preferred route of insulin delivery in critical care as doses can be rapidly adjusted to altered requirements. For stable patients, insulin can be added directly to the parenteral nutrition bag. If parenteral nutrition is infused continuously over 24 hours, the subcutaneous injection of a long-acting insulin combined with correctional bolus insulin may be adequate. The aim of this review is to give an overview of the management of parenteral nutrition-associated hyperglycemia in inpatients with diabetes.
RESUMO
BACKGROUND: Disease-related malnutrition is associated with loss of muscle mass and impaired functional status. Handgrip strength (HGS) has been proposed as an easy-to-use tool to assess muscle strength in clinical practice. OBJECTIVES: We investigated the prognostic implications of HGS in patients at nutritional risk with regard to clinical outcomes and response to nutritional support. METHODS: This was a secondary analysis of the randomized controlled, multicenter, Effect of Early Nutritional Support on Frailty, Functional Outcome, and Recovery of Malnourished Medical Inpatients Trial, which compared the effects of individualized nutritional support with usual hospital food in medical inpatients at nutritional risk. Our primary endpoint was 30-d all-cause mortality. The association between sex-specific HGS and clinical outcomes was investigated using multivariable regression analyses, adjusted for randomization, age, weight, height, nutritional risk, admission diagnosis, comorbidities, interaction terms, and study center. We used interaction terms to investigate possible effect modification regarding the nutritional support intervention. RESULTS: Mean ± SD HGS in the 1809 patients with available handgrip measurement was 17.0 ± 7.1 kg for females and 28.9 ± 11.3 kg for males. Each decrease of 10 kg in HGS was associated with increased risk of 30-d mortality (female: adjusted OR: 2.11; 95% CI: 1.23, 3.62, P = 0.007; male: adjusted OR: 1.44; 95% CI: 1.07, 1.93, P = 0.015) and 180-d mortality (female: adjusted OR: 1.45; 95% CI: 1.0, 2.10, P = 0.048; male: adjusted OR: 1.55; 95% CI: 1.28, 1.89, P < 0.001). Individualized nutritional support was most effective in reducing mortality in patients with low HGS (adjusted OR: 0.29; 95% CI: 0.10, 0.82 in patients in the ≤10th percentile compared with OR: 0.98; 95% CI: 0.66, 1.48 in patients in the >10th percentile; P for interaction = 0.026). CONCLUSIONS: In medical inpatients at nutritional risk, HGS provided significant prognostic information about expected mortality and complication risks and helps to identify which patients benefit most from nutritional support. HGS may thus improve individualization of nutritional therapy.This trial was registered at clinicaltrials.gov as NCT02517476.

OBJECTIVES: Malnutrition is highly prevalent in patients with aging-related vulnerability defined by very old age (≥80 y), physical frailty or cognitive impairment, and increases the risks for morbidity and mortality. The effects of individualized nutritional support for patients with aging-related vulnerability in the acute hospital setting on mortality and other clinical outcomes remains understudied. METHODS: For this secondary analysis of the randomized-controlled Effect of Early Nutritional Support on Frailty, Functional Outcomes, and Recovery of Malnourished Medical Inpatients Trial (EFFORT), we analyzed data of patients at a nutritional risk (Nutritional Risk Screening 2002 score ≥3 points) with aging-related vulnerability, randomized to receive protocol-guided individualized nutritional support to reach specific protein and energy goals (intervention group) or routine hospital food (control group). The primary endpoint was all-cause 30-d mortality. RESULTS: Of the 881 patients with aging-related vulnerability, 23.4% presented with a frailty syndrome, 81.8% were age ≥80 y and 15.3% showed cognitive impairment. Patients with aging-related vulnerability receiving individualized nutritional support compared with routine hospital food showed a >50% reduction in the risk of 30-day mortality (60 of 442 [13.6%] versus 31 of 439 [7.1%]; odds ratio: 0.48; 95% confidence interval, 0.31-0.76; P = 0.002). Significant improvements were also found for long-term mortality at 180 days, as well as functional outcomes and quality of life measures. CONCLUSIONS: Malnourished patients with aging-related vulnerability show a significant and clinically relevant reduction in the risk of mortality and other adverse clinical outcomes after individualized in-hospital nutritional support compared to routine hospital nutrition. These data support the early screening of patients with aging-related vulnerability for nutritional risk, followed by a nutritional assessment and implementation of individualized nutritional interventions.

BACKGROUND: In polymorbid patients with bronchopulmonary infection, malnutrition is an independent risk factor for mortality. There is a lack of interventional data investigating whether providing nutritional support during the hospital stay in patients at risk for malnutrition presenting with lower respiratory tract infection lowers mortality. METHODS: For this secondary analysis of a randomized clinical trial (EFFORT), we analyzed data of a subgroup of patients with confirmed lower respiratory tract infection from an initial cohort of 2028 patients. Patients at nutritional risk (Nutritional Risk Screening [NRS] score ≥3 points) were randomized to receive protocol-guided individualized nutritional support to reach protein and energy goals (intervention group) or standard hospital food (control group). The primary endpoint of this analysis was all-cause 30-day mortality. RESULTS: We included 378 of 2028 EFFORT patients (mean age 74.4 years, 24% with COPD) into this analysis. Compared to usual care hospital nutrition, individualized nutritional support to reach caloric and protein goals showed a similar beneficial effect of on the risk of mortality in the subgroup of respiratory tract infection patients as compared to the main EFFORT trial (odds ratio 0.47 [95%CI 0.17 to 1.27, p = 0.136] vs 0.65 [95%CI 0.47 to 0.91, p = 0.011]) with no evidence of a subgroup effect (p for interaction 0.859). Effects were also similar among different subgroups based on etiology and type of respiratory tract infection and for other secondary endpoints. CONCLUSION: This subgroup analysis from a large nutrition support trial suggests that patients at nutritional risk as assessed by NRS 2002 presenting with bronchopulmonary infection to the hospital likely have a mortality benefit from individualized inhospital nutritional support. The small sample size and limited statistical power calls for larger nutritional studies focusing on this highly vulnerable patient population. CLINICAL TRIAL REGISTRATION: Registered under ClinicalTrials.gov Identifier no. NCT02517476.

Malnutrition has been defined as a “state resulting from lack of uptake or intake of nutrition, leading to altered body composition and body cell mass, as well as to diminished physical and mental function and impaired clinical outcome from disease.” Particularly for the multimorbid medical inpatient, there are multiple research studies linking malnutrition to adverse clinical outcomes independent of type of acute and chronic illnesses. Importantly, recent trials have shown that malnutrition is indeed a modifiable risk factor with specific individualised nutritional support interventions started at hospital admission having positive effects on the risk of complications, mortality, functional outcomes, rehospitalisation and quality of life. Understanding the optimal use of nutritional support in patients with acute illness is complex – as timing, route of delivery, and the amount and type of nutrients can all affect patient outcome. The aim of this narrative review is to provide a practical guideline for pragmatic and evidence-based assessment and treatment of medical inpatients at nutritional risk. We thereby focus on screening, patient assessment, definition of individual nutritional goals and nutritional support interventions that help patients to reach these goals.

Evidence-based medicine is the art of combining "best external evidence", "clinical judgement" and "patient values" for improved daily clinical decision making and is the ultimate goal in modern medicine. Historically, in the field of medical nutrition, there had been a lack of strong evidence from large and high-quality trials resulting in often weak guideline recommendations and therefore insufficient implementation in clinical practice. Particularly in the field of malnutrition, the medical community has long struggled to find evidence-based approaches for effective management by means of screening, assessment and treatment of patients. With recent trials showing that individual medical nutrition therapy has strong effects on clinical outcomes, we should now aim to practice "evidence-based medical nutrition" (EBMN) by combining clinical judgement (e.g., thorough clinical assessment of the malnourished patient), patient preferences (e.g., integration of perspectives of patients and relatives, consideration of comorbidities to define specific energy/protein goals and appropriate route of medical nutrition therapy) and the most current scientific evidence (e.g., trial-supported use of nutritional interventions for individual patients). Such an approach may certainly be helpful to improve clinical outcomes of the vulnerable population of malnourished medical inpatients.

BACKGROUND: Low serum albumin levels resulting from inflammation-induced capillary leakage or disease-related anorexia during acute illness are associated with poor outcomes. We investigated the relationship of nutritional status and inflammation with low serum albumin levels and 30-day mortality in a large cohort. METHODS: We prospectively enrolled adult patients in the medical emergency department of a Swiss tertiary care center and investigated associations of C-reactive protein (CRP) and Nutritional Risk Screening 2002 as markers of inflammation and poor nutritional status, respectively, with low serum albumin levels and mortality using multivariate regression analyses. RESULTS: Among the 2465 patients, 1019 (41%) had low serum albumin levels (<34 g/L), 619 (25.1%) had increased nutritional risk (Nutritional Risk Screening 2002 ≥3), and 1086 (44.1%) had CRP values >20 mg/L. Multivariate analyses adjusted for age, gender, diagnosis, and comorbidities revealed elevated CRP values (adjusted odds ratio [OR] 10.51, 95% confidence interval, 7.51-14.72, P <.001) and increased malnutrition risk (adjusted OR 2.87, 95% confidence interval, 1.98-4.15, P <.001) to be associated with low serum albumin levels, even adjusting for both parameters. Low serum albumin levels, elevated CRP values, and increased nutritional risk independently predicted 30-day mortality, with areas under the curve of 0.77, 0.70, and 0.75, respectively. Combination of these 3 parameters showed an area under the curve of 0.82 to predict mortality. CONCLUSIONS: Elevated parameters of inflammation and high nutritional risk were independently associated with hypoalbuminemia. All 3 parameters independently predicted mortality. Combining them during initial evaluation of patients in emergency departments facilitates mortality risk stratification.

Survival after allogeneic stem cell transplantation (allo-HSCT) has improved, but so have long-term sequelae. We studied risk factors for fractures and impaired bone health in allo-HSCT patients in the Basel HSCT registry from 01/2003 to 12/2014 using cox proportional models adjusted for age, gender and Karnofsky Index. Our primary endpoint was the incidence of fractures. Out of 652 patients, 32 (5.0%) had a new fracture after transplantation (yearly incidence rate of 1.6%, 95% Confidence Interval [95%CI] 1.1-2.3%) and 325 (49.8%) had low bone mineral density (yearly incidence rate of 13.1%, 95%CI 11.6-14.8%), including 36.0% with osteopenia and 13.8% with osteoporosis. We found vitamin D deficiency during follow-up (Hazard Ratio [HR] 1.25, 95%CI 1.11-1.41, p < 0.001), hyperthyroidism before transplantation (HR 4.85, 95%CI 1.05-22.54, p = 0.044), cumulative years of immunosuppressant exposure (HR 1.23, 95%CI 1.07-1.41, p = 0.004 for steroidal and HR 1.09, 95%CI 1.01-1.18, p = 0.025 for non-steroidal drugs) and graft-versus-host disease (acute HR 1.24, 95%CI 1.11-1.40, p < 0.001; chronic HR 2.82, 95%CI 1.12-7.13, p = 0.028) to be significantly associated with fractures. Patients undergoing HSCT are at increased risk of fractures, which is associated with various disease and treatment-specific factors. Early identification of patients at risk may help to improve preventive measures.

Importance: Malnutrition affects a considerable proportion of the medical inpatient population. There is uncertainty regarding whether use of nutritional support during hospitalization in these patients positively alters their clinical outcomes. Objective: To assess the association of nutritional support with clinical outcomes in medical inpatients who are malnourished or at nutritional risk. Data Sources: For this updated systematic review and meta-analysis, a search of the Cochrane Library, MEDLINE, and Embase was conducted from January 1, 2015, to April 30, 2019; the included studies were published between 1982 and 2019. Study Selection: A prespecified Cochrane protocol was followed to identify trials comparing oral and enteral nutritional support interventions with usual care and the association of these treatments with clinical outcomes in non-critically ill medical inpatients who were malnourished. Data Extraction and Synthesis: Two reviewers independently extracted data and assessed risk of bias; data were pooled using a random-effects model. Main Outcomes and Measures: The primary outcome was mortality. The secondary outcomes included nonelective hospital readmissions, length of hospital stay, infections, functional outcome, daily caloric and protein intake, and weight change. Results: A total of 27 trials (n = 6803 patients) were included, of which 5 (n = 3067 patients) were published between 2015 and 2019. Patients receiving nutritional support compared with patients in the control group had significantly lower rates of mortality (230 of 2758 [8.3%] vs 307 of 2787 [11.0%]; odds ratio [OR], 0.73; 95% CI, 0.56-0.97). A sensitivity analysis suggested a more pronounced reduction in the risk of mortality in recent trials (2015 or later) (OR, 0.47; 95% CI, 0.28-0.79) compared with that in older studies (OR, 0.94; 95% CI, 0.72-1.22), in patients with established malnutrition (OR, 0.52; 95% CI, 0.34-0.80) compared with that in patients at nutritional risk (OR, 0.85; 95% CI, 0.62-1.18), and in trials with high protocol adherence (OR, 0.67; 95% CI, 0.54-0.84) compared with that in trials with low protocol adherence (OR, 0.88; 95% CI, 0.44-1.76). Nutritional support was also associated with a reduction in nonelective hospital readmissions (14.7% vs 18.0%; risk ratio, 0.76; 95% CI, 0.60-0.96), higher energy intake (mean difference, 365 kcal; 95% CI, 272-458 kcal) and protein intake (mean difference, 17.7 g; 95% CI, 12.1-23.3 g), and weight increase (0.73 kg; 95% CI, 0.32-1.13 kg). No significant differences were observed in rates of infections (OR, 0.86; 95% CI, 0.64-1.16), functional outcome (mean difference, 0.32; 95% CI, -0.51 to 1.15), and length of hospital stay (mean difference, -0.24; 95% CI, -0.58 to 0.09). Conclusions and Relevance: This study's findings suggest that despite heterogeneity and varying methodological quality among trials, nutritional support was associated with improved survival and nonelective hospital readmission rates among medical inpatients who were malnourished and should therefore be considered when treating this population.

OBJECTIVE: In 2009, international nutritional societies published practice guidelines on screening and nutritional support for patients undergoing stem cell transplantation. Little is known about how these guidelines are implemented in clinical practice. We performed a nationwide survey with the aim of understanding current practice patterns, differences between clinical practice, and international recommendations as well as barriers to the use of nutritional therapy. METHODS: We performed a qualitative survey including all centers across Switzerland offering allogeneic (n = 3) or autologous (n = 7) stem cell transplantation. We focused on in-house protocols pertaining to malnutrition screening, indications for nutritional support, types of nutritional therapy available and provided, and recommendations regarding neutropenic diets. RESULTS: All centers offering allogeneic, and most of the centers offering autologous transplantation, had a malnutrition screening tool, mainly the nutritional risk score (NRS 2002) method. Only one center does not provide nutritional support. There is wide variation regarding start and stop of nutritional therapy as well as route of delivery, with five centers recommending parenteral nutrition and five centers recommending enteral nutrition as a first step. Although all centers offering allogeneic transplantation, and approximately every other autologous transplant center, used a neutropenic diet, specific recommendations regarding the type of food and food handling showed significant variation. CONCLUSION: This Swiss survey found wide variation in the use of nutritional therapy in patients undergoing stem cell transplantation, with low adherence overall to current practice guidelines. Understanding and reducing barriers to guideline implementation in clinical practice may improve clinical outcomes. Close collaboration of centers will facilitate future research needed to improve current practice and ensure high quality of treatment.
