Global availability of parenteral nutrition: Pre- and post-COVID-19 pandemic surveys.

OBJECTIVE: Parenteral nutrition represents a therapeutic option for patients with type 3 intestinal failure. If used exclusively, parenteral nutrition has to be complete to provide all essential nutrients. The aim was to assess the availability of parenteral nutrition in all parts of the world, to better comprehend the global situation, and to prepare an action plan to increase access to parenteral nutrition. METHODS: An international survey using an electronic questionnaire was conducted in August 2019 and repeated in May 2022. An electronic questionnaire was sent to 52 members or affiliates of the International Clinical Nutrition Section of the American Society for Parenteral and Enteral Nutrition. Questions addressed the availability of parenteral nutrition admixtures and their components, reimbursement, and prescribing pre- and post-COVID-19 pandemic. All participating countries were categorized by their economic status. RESULTS: Thirty-six country representatives responded, answering all questions. Parenteral nutrition was available in all countries (100%), but in four countries (11.1%) three-chamber bags were the only option, and in six countries a multibottle system was still used. Liver-sparing amino acids were available in 18 (50%), kidney-sparing in eight (22.2%), and electrolyte-free in 11 (30.5%) countries (30.5%). In most countries (n = 28; 79.4%), fat-soluble and water-soluble vitamins were available. Trace elements solutions were unavailable in four (11.1%) countries. Parenteral nutrition was reimbursed in most countries (n = 33; 91.6%). No significant problems due to the coronavirus pandemic were reported. CONCLUSIONS: Despite the apparent high availability of parenteral nutrition worldwide, there are some factors that may have a substantial effect on the quality of parenteral nutrition admixtures. These shortages create an environment of inequality.

Association between the Static and Dynamic Lung Function and CT-Derived Thoracic Skeletal Muscle Measurements-A Retrospective Analysis of a 12-Month Observational Follow-Up Pilot Study.

BACKGROUND: Patients with chronic obstructive pulmonary disease (COPD) with low skeletal muscle mass and severe airway obstruction have higher mortality risks. However, the relationship between dynamic/static lung function (LF) and thoracic skeletal muscle measurements (SMM) remains unclear. This study explored patient characteristics (weight, BMI, exacerbations, dynamic/static LF, sex differences in LF and SMM, and the link between LF and SMM changes. METHODS: A retrospective analysis of a 12-month prospective follow-up study patients with stable COPD undergoing standardized treatment, covering mild to severe stages, was conducted. The baseline and follow-up assessments included computed tomography and body plethysmography. RESULTS: This study included 35 patients (17 females and 18 males). This study revealed that females had more stable LF but tended to have greater declines in SMM areas and indices than males (-5.4% vs. -1.9%, respectively), despite the fact that females were younger and had higher LF and less exacerbation than males. A multivariate linear regression showed a negative association between the inspiratory capacity/total lung capacity ratio (IC/TLC) and muscle fat area. CONCLUSIONS: The findings suggest distinct LF and BC progression patterns between male and female patients with COPD. A low IC/TLC ratio may predict increased muscle fat. Further studies are necessary to understand these relationships better.

Ethnic differences in CT derived abdominal body composition measures: a comparative retrospect pilot study between European and Inuit study population.

Understanding ethnic variations in body composition is crucial for assessing health risks. Universal models may not suit all ethnicities, and there is limited data on the Inuit population. This study aimed to compare body composition between Inuit and European adults using computed tomography (CT) scans and to investigate the influence of demographics on these measurements. A retrospective analysis was conducted on 50 adults (29 Inuit and 21 European) who underwent standard trauma CT scans. Measurements focused on skeletal muscle index (SMI), various fat indices, and densities at the third lumbar vertebra level, analyzed using the Wilcoxon-Mann-Whitney test and multiple linear regression. Inuit women showed larger fat tissue indices and lower muscle and fat densities than European women. Differences in men were less pronouncehd, with only Intramuscular fat density being lower among Inuit men. Regression indicated that SMI was higher among men, and skeletal muscle density decreased with Inuit ethnicity and age, while visceral fat index was positively associated with age. This study suggests ethnic differences in body composition measures particularly among women, and indicates the need for Inuit-specific body composition models. It higlights the importance of further research into Inuit-specific body composition measurements for better health risk assessment.

ESPEN practical guideline on clinical nutrition in acute and chronic pancreatitis.

Both acute and chronic pancreatitis are frequent diseases of the pancreas, which, despite being of benign nature, are related to a significant risk of malnutrition and may require nutritional support. Acute necrotizing pancreatitis is encountered in 20 % of patients with acute pancreatitis, is associated with increased morbidity and mortality, and may require artificial nutrition by enteral or parenteral route, as well as additional endoscopic, radiological or surgical interventions. Chronic pancreatitis represents a chronic inflammation of the pancreatic gland with development of fibrosis. Abdominal pain leading to decreased oral intake, as well as exocrine and endocrine failure are frequent complications of the disease. All of the above represent risk factors related to malnutrition. Therefore, patients with chronic pancreatitis should be considered at risk, screened and supplemented accordingly. Moreover, osteoporosis and increased facture risk should be acknowledged in patients with chronic pancreatitis, and preventive measures should be considered.

"More2Eat" in patients at nutritional risk during hospital stay lowers the risk of three-month mortality.

BACKGROUND & AIMS: Malnutrition is a common problem among hospitalized patients due to increased nutrient requirements and reduced food intake or uptake of nutrients. The aim of this prospective cohort study was to investigate the association of nutritional risk status (at or not at risk by NRS-2002) as well as energy and protein intake, use of oral nutritional supplements (ONS) and snack meals in at risk patients during hospitalization and adverse outcomes (length of stay (LOS), readmissions and mortality) at three-months follow-up. METHODS: Data were collected at baseline and at three-months follow-up in patients hospitalized at 31 units at a Danish University Hospital. Diet records were performed at baseline by using the nurses' quartile nutrition recording methods. Data about disease and clinical outcomes were collected from electronic medical records at baseline and three-months follow-up. RESULTS: A total of 318 patients were included. Patients at nutritional risk (n = 149, 47%) had higher risk of longer LOS (≥20 days (OR = 4.24 [1.81;9.95] and ≥30 days OR = 2.50 [1.22;5.14])), having one readmission (OR = 1.86 [1.15;3.01]) and death (OR = 2.56 [1.27;5.20]) compared to patients not at nutritional risk (n = 169, 53%). A longer LOS was associated with patients who achieved ≥75% of energy and protein requirements, consumed snack meals incl. and excl. oral nutritional supplements. Readmissions in patients at nutritional risk during the three-months were not associated with food intake during the index hospitalization. Mortality was observed in 43 of the 318 (13.5%) hospitalized patients. A lower mortality was associated with increased energy and protein intake in patients at nutritional risk. CONCLUSIONS: The results of this study indicate a longer LOS, higher readmission rate and increased mortality in patients at nutritional risk compared to patients not at risk. Patients at nutritional risk had lower risk of three-month mortality and longer LOS during index hospitalization with increased energy and protein intake. Readmissions in patients at nutritional risk were not affected by food intake. The association of nutritional risk with poorer outcomes indicates that good nutritional care including constant attention to food-intake during hospitalization can be beneficial regarding mortality.

The effect of nutritional interventions in acute radiation-induced diarrhoea in patients with primary pelvic cancer: A systematic review.

Acute radiation-induced diarrhoea (RID) is a well-known side effect of external radiation therapy for pelvic cancer. Acute RID is an unresolved clinical problem in approximately 80% of patients. We investigated the effect of nutritional interventions on acute RID in patients with pelvic cancer treated with curative radiotherapy. A search was conducted using PubMed, Embase.com, CINAHL, and Cochrane Library, from 1 January 2005 until 10 October 2022. We included randomised controlled trials or prospective observational studies. Eleven of the 21 identified studies had low quality of evidence, mainly because of low patient numbers distributed among several cancer diagnoses, and non-systematic assessment of acute RID. Interventions included probiotics (n = 6), prebiotics (n = 6), glutamine (n = 4), and others (n = 5). Five studies, of which two provided high quality evidence, showed that probiotics improved acute RID. Future well-designed studies investigating the effects of probiotics on acute RID are warranted.

Association between thoracic and third lumbar CT-derived muscle mass and density in Caucasian patients without chronic disease: a proof-of-concept study.

BACKGROUND: Computed tomography (CT) is increasingly used in the clinical workup, and existing scan contains unused body composition data, potentially useful in a clinical setting. However, there is no healthy reference for contrast-enhanced thoracic CT-derived muscle measures. Therefore, we aimed at investigating whether there is a correlation between each of the thoracic and third lumbar vertebra level (L3) skeletal muscle area (SMA), skeletal muscle index (SMI), and skeletal muscle density (SMD) at contrast-enhanced CT in patients without chronic disease. METHODS: A proof-of-concept retrospective observational study was based on Caucasian patients without chronic disease, who received CT for trauma between 2012 and 2014. Muscle measures were assessed using a semiautomated threshold-based software by two raters independently. Pearson's correlation between each thoracic level and third lumbar and intraclass correlation between two raters and test-retest with SMA as proxy parameters were used. RESULTS: Twenty-one patients (11 males, 10 females; median age 29 years) were included. The second thoracic vertebra (T2) had the highest median of cumulated SMA (males 314.7 cm2, females 118.5 cm2) and SMI (97.8 cm2/m2 and 70.4 cm2/m2, respectively). The strongest SMA correlation was observed between T5 and L3 (r = 0.970), the SMI between T11 and L3 (r = 0.938), and the SMD between the T10 and L3 (r = 0.890). CONCLUSIONS: This study suggests that any of the thoracic levels can be valid to assess skeletal muscle mass. However, the T5 may be most favourable for measuring SMA, the T11 for SMI, and T10 for SMD when using contrast-enhanced thoracic CT. RELEVANCE STATEMENT: In COPD patients, a CT-derived thoracic muscle mass assessment may help identify who would benefit from focused pulmonary rehabilitation: thoracic contrast-enhanced CT conducted as part of the standard clinical workup can be used for this evaluation. KEY POINTS: • Any thoracic level can be used to assess thoracic muscle mass. • Thoracic level 5 is strongly associated with the 3rd lumbar muscle area. • A strong correlation between the thoracic level 11 and the 3rd lumbar muscle index. • Thoracic level 10 is strongly associated with the 3rd lumbar muscle density.

Management of acute mesenteric ischaemia: Results of a worldwide survey.

BACKGROUND: Acute mesenteric ischaemia (AMI) is a condition with high mortality. This survey assesses current attitudes and practices to manage AMI worldwide. METHODS: A questionnaire survey about the practices of diagnosing and managing AMI, endorsed by several specialist societies, was sent to different medical specialists and hospitals worldwide. Data from individual health care professionals and from medical teams were collected. RESULTS: We collected 493 individual forms from 71 countries and 94 team forms from 34 countries. Almost half of respondents were surgeons, and most of the responding teams (70%) were led by surgeons. Most of the respondents indicated that diagnosis of AMI is often delayed but rarely missed. Emergency revascularisation is often considered for patients with AMI but rarely in cases of transmural ischaemia (intestinal infarction). Responses from team hospitals with a dedicated special unit (14 team forms) indicated more aggressive revascularisation. Abdominopelvic CT-scan with intravenous contrast was suggested as the most useful diagnostic test, indicated by approximately 90% of respondents. Medical history and risk factors were thought to be more important in diagnosis of AMI without transmural ischaemia, whereas for intestinal infarction, plasma lactate concentrations and surgical exploration were considered more useful. In elderly patients, a palliative approach is often chosen over extensive bowel resection. There was a large variability in anticoagulant treatment, as well as in timing of surgery to restore bowel continuity. CONCLUSIONS: Delayed diagnosis of AMI is common despite wide availability of an adequate imaging modality, i.e. CT-scan. Large variability in treatment approaches exists, indicating the need for updated guidelines. Increased awareness and knowledge of AMI may improve current practice until more robust evidence becomes available. Adherence to the existing guidelines may help in improving differences in treatment and outcomes.

Are nutritional sufficiency of ≥75% energy and protein requirements relevant targets in patients at nutritional risk? - A one month follow-up study.

BACKGROUND & AIM: Nutrient intake in patients at nutritional risk was recorded with the aim of reaching at least 75% of estimated requirements for energy and protein. However, the cutoff at 75% has only been sparsely investigated. The aim of this study was to re-evaluate the 75% cutoff of estimated energy and protein requirements among patients at or not at nutritional risk in relation to 30-day mortality and readmissions. METHODS: A 30-day follow-up study was performed among hospitalized patients in 31 units at a Danish University Hospital. Data was collected using the nurses' quartile nutrition registration method and electronic patient journals. All patients were screened using the NRS-2002 and classified as either at nutritional risk (NRS-2002, score ≥3) or not at nutritional risk (NRS-2002, score <3). Energy and protein requirements were estimated using weighted Harris-Benedict equation and 1.3 g/kg/day, respectively. RESULTS: In total, 318 patients were included in this study. Patients at nutritional risk were older, lower BMI, male, more comorbidities and a longer primary length of stay compared to patients not at nutritional risk (p < 0.05). After 30-day follow-up, mortality was higher among patients at risk (9.5% vs. 2.0%, p < 0.05). Patients at nutritional risk showed increased risk of mortality if they did not achieve 75% of estimated requirements (energy: OR = 8.08 [1.78; 36.79]; protein: OR = 3.40 [0.74; 15:53]). Furthermore, predicted probability of mortality decreased with increased energy and protein intakes. No significant associations were found for readmissions achieving 75% of estimated energy or protein requirements. A cutoff of 76-81% for energy and 58-62% for protein was equivalent with accepting a 6-8% mortality rate. CONCLUSION: The results of this study indicate that an energy intake ≥75% of estimated requirement among patients at nutritional risk has a preventative effect regarding mortality within one month, but not for readmissions.

Malnutrition in Patients With Moderate to Severe Acquired Brain Injury: Prevalence During 4 Weeks of Subacute Rehabilitation.

ABSTRACT: BACKGROUND: Malnutrition is associated with high rates of complication, longer hospital stays, and increased morbidity and mortality. Malnutrition defined as undernutrition is common in patients with acquired brain injury (ABI); however, estimates vary remarkably. This study aimed to describe malnutrition at admission and after 4 weeks of subacute inpatient neurorehabilitation in patients with ABI using the new global consensus definition of malnutrition. METHODS: One hundred thirty-three patients with moderate to severe ABI consecutively admitted to a specialized neurorehabilitation hospital within a period of 4 months were screened for inclusion, of which 92 were included. Malnutrition was defined as at least 1 phenotypic criterion (weight loss, low body mass index, low muscle mass) and at least 1 etiologic criterion (reduced food intake, inflammation). Malnutrition on admission and after 4 weeks was compared using the McNemar test. RESULTS: The proportion of patients with malnutrition at admission was 42%, with more men (46%) than women (36%) fulfilling the criteria for malnutrition. The most frequent phenotypic and etiologic criteria were weight loss (56%) and inflammation (74%), respectively. During the 4 weeks of rehabilitation, the proportion of male patients fulfilling the individual criteria "weight loss" (difference, -21.4%) and "inflammation" (difference, -18.9%) decreased significantly; "low muscle mass" decreased borderline significant (difference, -8.9%), whereas "low body mass index" did not change. The proportion of female patients fulfilling individual criteria for malnutrition was stable or increased nonsignificantly. CONCLUSION: Malnutrition was common at admission to neurorehabilitation in patients with moderate to severe ABI, with more men than women fulfilling the criteria for malnutrition. The nutritional status improved after 4 weeks of rehabilitation in male patients, whereas it was largely unchanged in female patients. The results provide the basis for monitoring high-quality nutritional nursing care.

GLIM diagnosed malnutrition predicts clinical outcomes and quality of life in patients with non-small cell lung cancer.

BACKGROUND & AIMS: The high prevalence of malnutrition in non-small cell lung cancer (NSCLC) patients has numerous negative consequences on patients' outcome when undergoing anti-neoplastic treatment. The Global Leadership Initiative on Malnutrition (GLIM) criteria for diagnosis of malnutrition are currently being verified; however, studies validating GLIM criteria in NSCLC patients are lacking. This study aimed to evaluate clinical outcomes and Quality of Life (QoL) in malnourished compared to well-nourished NSCLC patients to determine the predictive validity of GLIM criteria. METHODS: We collected data on adverse events, survival, and QoL from NSCLC patients undergoing first line anti-neoplastic treatment collected from two prospective trials. Patients were categorized by GLIM criteria as malnourished or well-nourished, based on non-volitional weight loss, low Body Mass Index, reduced muscle mass (Computed Tomography-scans), reduced food intake (24-h recall), and inflammatory condition (modified Glasgow Prognostic Score). Differences in descriptive data, adverse events, survival, and QoL between the malnourished and well-nourished patients were analyzed. RESULTS: Overall, 120 patients were included in the study. Malnourished patients compared to well-nourished patients had significantly worse outcome in terms of treatment cessation (n = 21 vs 13, p = 0.049), disease progression (n = 20 vs 12, p = 0.034) and shorter overall survival (HR 2.0, 95% CI: 1.2, 3.4, p = 0.009). Stratifying by severity, moderately malnourished patients had a shorter overall survival compared to well-nourished patients (HR 2.1, 95% CI: 1.2, 3.6, p = 0.007). Malnutrition at baseline was associated with poor QoL by lower physical (p < 0.001) and role functioning (p = 0.011), more symptoms of fatigue (p = 0.001), nausea and vomiting (p = 0.009), pain (p < 0.001), dyspnea (p = 0.032), appetite loss (p < 0.001), and constipation (p = 0.029). No significant differences were found in hospitalization, dose reductions, or treatment postponement. CONCLUSIONS: Malnutrition defined by GLIM criteria in NSCLC patients was associated with more frequent early cessation of anti-neoplastic treatment, shorter overall survival, and poorer QoL compared to well-nourished patients.

Evaluation of Multi-Frequency Bioelectrical Impedance Analysis against Dual-Energy X-ray Absorptiometry for Estimation of Low Muscle Mass in Older Hospitalized Patients.

The accuracy of multi-frequency (MF) bioelectrical impedance analysis (BIA) to estimate low muscle mass in older hospitalized patients remains unclear. This study aimed to describe the ability of MF-BIA to identify low muscle mass as proposed by The Global Leadership Initiative on Malnutrition (GLIM) and The European Working Group on Sarcopenia in Older People (EWGSOP-2) and examine the association between muscle mass, dehydration, malnutrition, and poor appetite in older hospitalized patients. In this prospective exploratory cohort study, low muscle mass was estimated with MF-BIA against dual-energy X-ray absorptiometry (DXA) in 42 older hospitalized adults (≥65 years). The primary variable for muscle mass was appendicular skeletal muscle mass (ASM), and secondary variables were appendicular skeletal muscle mass index (ASMI) and fat-free mass index (FFMI). Cut-off values for low muscle mass were based on recommendations by GLIM and EWGSOP-2. MF-BIA was evaluated against DXA on the ability to estimate absolute values of muscle mass by mean bias, limits of agreement (LOA), and accuracy (5% and 10% levels). Agreement between MF-BIA and DXA to identify low muscle mass was evaluated with sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV). The association between muscle mass, dehydration, malnutrition, and poor appetite was visually examined with boxplots. MF-BIA overestimated absolute values of ASM with a mean bias of 0.63 kg (CI: -0.20:1.46, LOA: -4.61:5.87). Agreement between MF-BIA and DXA measures of ASM showed a sensitivity of 86%, specificity of 94%, PPV of 75% and NPV of 97%. Boxplots indicate that ASM is lower in patients with malnutrition. This was not observed in patients with poor appetite. We observed a tendency toward higher ASM in patients with dehydration. Estimation of absolute ASM values with MF-BIA should be interpreted with caution, but MF-BIA might identify low muscle mass in older hospitalized patients.

Body composition measures may help target fundamental nutritional nursing efforts in rehabilitating patients with acquired brain injury.

AIM: To illuminate using body composition measurements for malnutrition measured by Bio Impedance Analysis (BIA), as opposed to body mass index (BMI), and discuss benefits and burdens for fundamental nursing care. DESIGN: A second analysis of a prospective, descriptive cohort study, targeting fundamental nursing care elements. METHODS: This postevaluation study explored data from a prospective, descriptive cohort study, which consecutively included 92 patients admitted for neurorehabilitation care. Measures of nutritional status were BMI and FFMI. Chi-Square test and Multivariable logistic regression were used. RESULTS: Body composition measures rather than BMI contributed to target individual nutritional nursing care as this measure detected more patients at potential risk of malnutrition and indicated minor changes in the nutritional state. Transitions from being malnourished to a normal nutritional status occurred in 29% using the BMI definition while it was the case in 40% of individuals with malnutrition defined by the body composition.

A multimodal nutritional intervention after discharge improves quality of life and physical function in older patients - a randomized controlled trial.

BACKGROUND: Many older hospitalized patients are at nutritional risk or malnourished and the nutritional condition is often further impaired during hospitalization. When discharged to own home, a "Nutrition Gap" often occurs, causing inadequate dietary intake, and potentially impeded recovery. Previously, cross-sectorial studies of single component nutritional intervention have shown a limited effect on clinically relevant outcomes. We hypothesized that a multimodal nutritional intervention is necessary to elicit a beneficial effect on clinically relevant outcomes. METHODS: A randomized controlled trial was performed for a period of 16 weeks. At discharge, the intervention group (IG) received dietetic counselling including a recommendation of daily training, an individual nutrition plan and a package containing foods and drinks covering dietary requirements for the next 24 h. Further, a goodie-bag containing samples of protein-rich milk-based drinks were provided. Information regarding recommendations of nutritional therapy after discharge was systematically and electronically communicated to the municipality. The dietician performed telephone follow-ups on day 4 and 30 and a home visit at 16 weeks. The control group (CG) received standard treatment. The primary outcome was readmissions within 6 month, secondary outcomes were Length of Stay (LOS), Health Related Quality of Life (EQ-5D-3L), nutritional status, physical function (30s-CST) and mortality. This trial was registered under ClinicalTrials.gov Identifier no. NCT03488329. RESULTS: We included 191 patients (IG: n = 93). No significant difference was seen in readmissions within 6 month (IG: 45% vs. CG: 45%, Risk Ratio (RR): 0.96 0.71-1.31, p = 0.885). At the 16-weeks follow-up more patients in the IG reached at least 75% of energy and protein requirements (82% vs. CG: 61%, p = 0,007). The energy (kcal) and protein intake (g) per kg was significantly higher in the IG (26.4 kcal/kg (±7.4) vs. 22.6 (±7.4), p = 0.0248) (1.1 g/kg (±0.3) vs. 0.9 g/kg (±0.3). Furthermore, significant lower weight loss was seen in IG (0.7 (±4.3) vs. -1.4 (±3.6), p = 0.002). A significant and clinically relevant difference was found in the EQ-5D-3L VAS-score (IG: mean 61.6 ± 16.2 vs. CG: 53.3 ± 19.3, p = 0.011) (Δ14.3 (±15.5) vs. Δ5.6 (±17.2), p = 0.002). A significant difference in mean 30s-CST in IG was also found (7.2 (±4.3) vs. 5.3 (±4.1), p = 0.010). The improvements in physical function were of clinical relevance in both groups, but significantly higher in the IG (Δ4.2 (±4.4) vs. Δ2.2 (±2.5), p = 0.008). In fact, 86% in IG experienced improvements in the 30s-CST compared with 68% in the CG (p = 0.022). LOS was found to be lower at all time points, however not significant (30 days: -3 (-8.5 to 2.5), p = 0.276, 16 weeks: -4 (-10.2 to 2.2, p = 0.204), 6 months: -3 (-9.3 to 3.3, p = 0346)). All-cause mortality was not different between groups, however RR showed a non-significantly 47% reduction at day 30 (0.53 (0.14-2.05, p = 0.499)) and a 17% reduction at 16 weeks (0.83 (0.40-1.73, p = 1.000)) in IG. Per protocol (PP) analysis revealed a non-significant decrease of 32% in readmission at 6 months (RR: 0.68 (0.42-1.08), p = 0.105). CONCLUSION: The present study, using a multimodal nutritional approach, revealed no significant effect on readmissions however a significant positive effect on nutritional status, quality of life and physical function was found. The improvements in quality of life and physical function were of clinical relevance. No significant effect was found on LOS and mortality.

Personalized exercise intervention in HPN patients - A feasibility study.

BACKGROUND: Physical health status may be predictive of readmissions, psychological health and mortality in patients with short bowel syndrome. AIMS: This study aimed to investigate the feasibility and effect of an individualized exercise intervention and secondary, oral nutrition intake counseling on Timed-Up-and-Go (TUG) and 30 s Chair Stand Test (CST) as well as body-composition and EuroQol (EQ)-5D-5L, in patients with chronic intestinal failure (IF) type III receiving HPN and/or fluid therapy. METHODS: A 12-week individualized exercise intervention consisting on three weekly home based sessions, and nutrition counselling focusing on protein intake and reducing high stoma output, was performed. Weekly follow-up by phone was done on motivation to exercise. RESULTS: The study invited 71 patients, 44 accepted the invitation (62%), 37(52%) were included, and 31 (84%) completed the intervention. The exercise intervention was well tolerated. TUG improved from 8.9(SD 5.5) to 7.7(SD 3.8) (p = 0.033). CST improved by four repetitions (<0.001∗). A statistical, however not clinically relevant improvement was seen in muscle mass. No improvement was seen in (EQ)-5D-5L total, but insignificantly (p = 0.055) for physical function only. Protein intake improved by 10.6 g/day (p = 0.008). CONCLUSIONS: A 12 weeks individualized exercise intervention showed very feasible and beneficial in HPN patients. Physical function improved statistically and clinically, and oral protein intake improved. QoL overall did not improve, however COVID-19 was an uninvited partner throughout the study period, which may have influenced general QoL. As only 62% accepted the invitation to participate, home based exercise intervention may not apply to all patients.

Signs of dysphagia and associated outcomes regarding mortality, length of hospital stay and readmissions in acute geriatric patients: Observational prospective study.

BACKGROUND AND AIMS: Dysphagia is a prevalent disorder in acute geriatric patients. This observational prospective study aimed at investigating adverse clinical outcomes linked to signs of dysphagia, including mortality, length of hospital stay (LOS), readmissions, among patients aged ≥ 65 years at a Danish acute medical unit (AMU). METHODS: Signs of dysphagia were assessed using bedside screening tools including the Eating Assessment Tool (EAT-10), a 30 mL Water Swallowing Test (WST) and the Gugging Swallowing Screen tool (GUSS), as described in the preceding cross-sectional study. Data for the follow-up was twice retrieved from electronic medical charts 30 days and 90 days after the patients' primary admission to the hospital. Statistical analysis included non-parametric tests of independence and proportional hazards modelling. RESULTS: 444 patients were recruited, 334 of whom completed the dysphagia screening with 144 (43.1 %) showing signs of dysphagia. Patients with signs of dysphagia, compared to those without, experienced higher mortality after 30 days (12.5 % vs. 1.6 %, p < 0.001) and 90 days (21.5 % vs. 5.8 %, p < 0.001), longer LOS (median [Q1; Q3]: 4 [2; 8] vs. 3 [1; 6] days, p = 0.004), more total hospital days (THD) during both the 30-day and 90-day follow-up (for 90d: median [Q1; Q3]: 6 [2.25; 12] vs. 4 [2; 9] days, p = 0.007), but no significant difference in frequency of readmissions. Multivariate proportional hazards modelling revealed signs of dysphagia, low performance status and high comorbidity to be independent risk factors for mortality. High comorbidity and low hemoglobin, but not signs of dysphagia, were revealed as independent risk factors for readmission. CONCLUSION: Dysphagia is a notable risk factor linked to increased mortality and length of hospital stay (LOS) for acute geriatric patients in general, not just those suffering from stroke, head and neck cancer or neurodegenerative diseases. Further research is needed to investigate the effectiveness and feasibility of systematic dysphagia screening within this population.

Oral absorption of oxycodone in patients with short bowel syndrome.

BACKGROUND: Short bowel syndrome is a disorder with several complications such as malnutrition and failure of drug therapy. Treatment with opioids is needed in many patients, and oral medication is preferred. However, optimal dosing is a difficult task as current guidelines are based on an intact gastrointestinal tract. Hence, the aim of this explorative case study was to assess the pharmacokinetics of orally administered oxycodone in patients with short bowel syndrome. METHODS: Six patients with short bowel syndrome were administered 10 mg oral solution oxycodone after an overnight fast. Oxycodone plasma concentrations were determined over a 6-hour period. Pharmacokinetic profiles were visually inspected. Pharmacokinetic parameters: maximum plasma concentration, time of maximum concentration and area under the curve were calculated. Data were also compared to mean values obtained in healthy participants. RESULTS: A clinically relevant concentration of oxycodone was found in all patients, although with large inter-individual variation. The absorption fraction tended to correlate positively with total intestinal length. Additionally, preservation of some or the entire colon seemed further to increase the absorption fraction. Time of maximum concentration varied from 30 min to approximately 90 min. CONCLUSIONS: Oxycodone is absorbed in a clinically relevant extent in patients with short bowel syndrome, but bioavailability varies greatly between patients, which shall be taken into consideration. Absorption is related to functional small intestinal length, but preservation of colon is also beneficial. Still, optimal therapeutic dosing must be individualized, and other factors such as those related to malnutrition and motility shall also be taken into consideration.

Measurement of body composition: Agreement between methods of measurement by bioimpedance and computed tomography in patients with non-small cell lung cancer.

BACKGROUND AND AIMS: Cancer cachexia is a muscle wasting syndrome which is promoted by the presence of inflammation and metabolic changes. Cancer cachexia has shown predictable for survival, progression of physical impairment as well as patient-reported outcomes. Being able to identify these patients with a clinically applicable method for measuring body composition could lead to early nutritional intervention, possibly preventing progression of cancer cachexia. This study aimed to investigate the agreement between body composition recorded with bioelectrical impedance analysis (BIA) and software analysis of CT scans of patients suffering from cancer with a special emphasis on muscle mass. METHODS: This is a cross-sectional study of newly diagnosed patients with non-small cell lung cancer. All patients had muscle mass (MM) and fat mass (FM) measured by BIA with Tanita Segmental Body Composition Analyzer (BC-418) and by software analysis of CT scans at L3-level with VikingSlice. Secondary parameters (systemic inflammation, physical performance and electrolyte balance) were investigated for possible pitfalls of BIA. Patients who fulfilled best standard practice for BIA measurements, including 4 h of fasting, absence of oedema and no metallic implants, participated in a subgroup analysis. Agreement between method of measurements is investigated with the Bland and Altman method and pitfalls with paired t-test. A satisfactory agreement of BIA and CT measurements is established as ±10%. RESULTS: A total of 60 patients participated in the study amongst which 37 participated in the subgroup analysis. The bias between methods of measurement for MM was 4.74 ± 11.55% (P = 0.002) with limits of agreement (LoA) of -17.91 to 27.38%. In the subgroup analysis, the bias of MM was 3.06 ± 10.71% (P = 0.091) and LoA were -17.94 to 24.06%. In the analysis of secondary parameters, significant differences between methods were found in patients with normal hand grip strength (1.83 kg, P = 0.023) and those performing under gender and age-specific cut-offs in the 30-s sit to stand test (5.15 kg, P = 0.009). CONCLUSIONS: BIA and CT image analysis were not comparable for body composition measurements. BIA overestimated MM and underestimated FM with LoA outside that of the clinically assessed acceptable difference. Bias was reduced and LoA narrowed in the subgroup analysis however not to acceptable levels. This study finds it possible that patients with low physical performance are liable to larger overestimations of MM with BIA than those with normal physical performance.

Different GLIM criteria combinations change prevalence of malnutrition in patients with intestinal insufficiency or intestinal failure.

BACKGROUND & AIM: Due to lack of global consensus in diagnosing malnutrition, Global Leadership Initiative on Malnutrition (GLIM) has suggested the GLIM criteria based on etiological and phenotypical criteria. The aim of this study was to investigate the prevalence of malnutrition in patients with intestinal insufficiency (INS) or intestinal failure (IF) based on the different GLIM criteria combinations to diagnose malnutrition. Furthermore, the aim was to investigate the severity of malnutrition in the two patient groups. METHODS: A cross-sectional study with INS patients on enteral nutrition and IF patients on home parenteral nutrition. We recorded age, gender, weight, height, fat free mass index (FFMI) by bioelectrical impedance analysis, handgrip strength (HGS), arm muscle circumference (AMC) and biochemical parameters: plasma albumin (p-alb) and plasma C-reactive protein (p-CRP). Further, we calculated Glasgow prognostic score (GPS) and body mass index (BMI). STATISTICS: T-test, Chi-square test and simple logistic regression analysis. Significance level: p < 0.05. RESULTS: In total 277 INS and IF patients were included (age 59.5 ± 15.2 years, male 43,7%, BMI 22.1 ± 4.3 kg/m2). Groups were comparable according to number, age and gender but more IF patients had decreased BMI, p-alb, HGS and FFMI and increased CRP and GPS 1 or 2. Prevalence of malnutrition using GPS 1 or 2 combined with BMI, FFMI or HGS was 22.6%, 23.4%, 26.3% for INS, respectively (p = 0.756) and 40.7%, 40.0%, 59.3% for IF, respectively (p = 0.001). Agreement between the criteria combinations were: 8.0% for INS and 25.7% for IF. Significantly more with IF was diagnosed with severe malnutrition as compared to no malnutrition (43 vs. 26, p = 0.012, OR 2.1 [CI95% 1.2-3.8]), but only a tendency in the group with moderate malnutrition as compared to no malnutrition (27 vs. 22, p = 0.180, OR 1.6 [CI95% 0.8-3.0]) CONCLUSION: We found both prevalence and severity of malnutrition to be higher in IF than INS patients. GLIM-criteria were able to identify approximately same prevalence of malnutrition in INS but not in IF, when combining GPS 1 or 2 with BMI, FFMI and HGS. However, the agreement was poor in both groups. Consequently, further validation of GLIM is needed - including association to clinical outcome in lack of a gold standard.

Urinary creatinine based equations for estimation of fat free mass in patients with intestinal insufficiency or intestinal failure.

BACKGROUND & AIMS: Assessment of body composition is an important aspect of disease management in patients with intestinal insufficiency (INS) or intestinal failure (IF). However, in daily clinical settings most body composition methods are too expensive or impractical, leaving body composition to be assessed by less reliable methods such as skin fold thickness. The aim of this study was to investigate and validate the use of an equation for the estimation of fat-free mass (FFM) with bioelectrical impedance analysis (BIA) as reference method. METHODS: A literature search for identification of urinary creatinine-based FFM-prediction equations was carried out a long side the creation of an equation by multiple linear regression. The correlation of each equation with FFM (measured by BIA in 277 patients with either INS or IF) was done by Pearson's correlation. Further investigation and validation of performance was done for the equations with the strongest correlation by Bland-Altman analysis, determination of root mean square error (RMSE), and intraclass correlation (ICC). The validation was carried out in a new group of 37 patients with either INS or IF. RESULTS: A total of 11 prediction equations were correlated with FFM measured by BIA. The equation called FFMmultiple and FFM-5 had the strongest correlation (r = 0.969, p < 0.01 and r = 0.950, p < 0.01, respectively). FFMmultiple was superior to FFM-5 regarding Bland-Altman analysis, RMSE, and ICC in the study group (Mean bias ± Standard Deviation = 0.042 ± 2.352 versus 0.309 ± 3.196; 95% limits of agreement = [-4.568; 4.651] versus [-5.955; 6.578]; RMSE = 0.158 versus 0.236; ICC = 0.969 versus 0.948). Cross-validation resulted in a Bland-Altman analysis with a statistically significant difference between FFMmultiple and FFM by BIA. FFM-5 showed wide 95% limits of agreement ([-6.977; 6.421]). CONCLUSIONS: Two urinary creatinine-based equations (FFMmultiple and FFM-5) showed promising results as possible substitutes to BIA, however further investigation and cross validation revealed inauspicious results. Thus, the present study cannot recommend the use of a prediction equation instead of BIA for the assessment of FFM in patients with INS and IF.
