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.

Role of bacteria and microbial metabolites in immune modulation during early life.

Host-microbiome interplay from birth is essential for immune imprinting and tuning. Live gut microbes and microbial-derived metabolites regulate the development and modulation of the immune system, but whether microbial metabolites solely are sufficient to induce immune maturation remains unclear. Sterile faecal filtrates (FFT) were generated from murine gut contents. Newborn germ-free (GF) mice were treated twice daily with FFT (GF-FFT) or saline (GF-NaCl) from post-natal day 5 until 4 weeks of age. A third group of GF neonates were conventionalized by the transfer of caecal microbiota with live gut microbes. Host immune compartments were comprehensively immunophenotyped and systemically analysed in all available immune-related organs using flow cytometry. Oral FFT was associated with reduced survival among neonates (n = 7/19; 36.8% mortality), while saline treatment was well tolerated (n = 1/17, 5.9% mortality). Four-week-old FFT-treated pups were comparable in body weight to GF-NaCl, and the major B-cell, conventional T-cell and unconventional T-cell subsets were unchanged from saline-treated mice. Live bacteria administered during early life induced clear changes in proportions of B cells, T cells and T-cell subsets in all mucosal tissues and secondary lymphoid organs compared to GF-FFT, including restoration of intestinal natural killer T (NKT) cells with characteristics similar to conventional pups. Our findings show that oral administration of a FFT made of microbial metabolites, antigens and bacteriophages alone is insufficient to induce normal immune development elicited by the presence of live bacteria. Reduced survival during neonatal FFT treatment suggests a potential bioactive attribute of sterile faecal filtrates.

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.

Clinical efficacy of buprenorphine after oral dosing in rats undergoing major surgery.

Serum corticosterone, serum buprenorphine, body weight change, consumption of food and water and behaviour-based pain assessment were measured in catheterised and non-catheterised male Wistar rats undergoing myocardial infarct (MI) surgery under general anaesthesia following buprenorphine dosing by subcutaneous (Bup-SC, 0.05 mg/kg) and oral (Bup-O, 0.4 mg/kg) routes. Buprenorphine was dosed subcutaneously at half an hour before and 8, 16 and 24 hours after surgery (Bup-SC), orally at one hour before surgery (Bup-O1) or at one hour before and 12 hours after surgery (Bup-O2) in catheterised rats and at one hour before and 24 hours after surgery (Bup-O24) in non-catheterised rats. Serum corticosterone, body weight changes and food and water consumption were not significantly different between treatments in catheterised rats. Bup-SC resulted in rapidly decreasing serum concentrations below the clinically effective concentrations (1 ng/mL) already at two hours after the first dose. Bup-O provided significantly higher and slowly decreasing serum concentrations, at or above clinically effective concentrations, for 24 hours (Bup-O1) and 42 hours (Bup-O2) after surgery. In non-catheterised rats, body weight development and food consumption were significantly higher in Bup-O24 rats compared to Bup-SC rats. The results indicate that a SC buprenorphine dose of 0.05 mg/kg every eight hours provides long periods of serum concentrations below clinically effective levels, and that a higher dose and/or more frequent dosage are required to provide stable serum concentrations at or above clinically effective levels. A single oral buprenorphine dose of 0.4 mg/kg provides clinically effective and stable serum concentrations for 24 hours in rats after MI surgery.

Microbial exposure during early life regulates development of bile duct inflammation.

OBJECTIVES: The early life microbiome has been linked to inflammatory diseases in adulthood and a role for the microbiome in bile duct inflammation is supported by both human and murine studies. We utilized the NOD.c3c4 mouse model that develops a spontaneous immune-driven biliary disease with a known contribution of the microbiome to evaluate the temporal effects of the early life microbiome. MATERIALS AND METHODS: Germ-free (GF) NOD.c3c4 mice were conventionalized into a specific pathogen free environment at birth (conventionally raised, CONV-R) or at weaning (germ-free raised, GF-R) and compared with age and gender-matched GF and conventional (CONV) NOD.c3c4 mice. At 9 weeks of age, liver pathology was assessed by conventional histology and flow cytometry immunophenotyping. RESULTS: Neonatal exposure to microbes (CONV-R) increased biliary inflammation to similar levels as regular conventional NOD.c3c4 mice, while delayed exposure to microbes (GF-R) restrained the biliary inflammation. Neutrophil infiltration was increased in all conventionalized mice compared to GF. An immunophenotype in the liver similar to CONV was restored in both CONV-R and GF-R compared to GF mice displaying a proportional increase of B cells and reduction of T cells in the liver. CONCLUSIONS: Microbial exposure during early life has a temporal impact on biliary tract inflammation in the NOD.c3c4 mouse model suggesting that age-sensitive interaction with commensal microbes have long-lasting effects on biliary immunity that can be of importance for human cholangiopathies.

Molnupiravir Revisited-Critical Assessment of Studies in Animal Models of COVID-19.

Molnupiravir, a prodrug known for its broad antiviral activity, has demonstrated efficacy in animal models of COVID-19, prompting clinical trials, in which initial results indicated a significant effect against the disease. However, subsequent clinical studies did not confirm these findings, leading to the refusal of molnupiravir for permanent market authorization in many countries. This report critically assessed 22 studies published in 18 reports that investigated the efficacy of molnupiravir in animal models of COVID-19, with the purpose of determining how well the design of these models informed human studies. We found that the administered doses of molnupiravir in most studies involving animal COVID-19 models were disproportionately higher than the dose recommended for human use. Specifically, when adjusted for body surface area, over half of the doses of molnupiravir used in the animal studies exceeded twice the human dose. Direct comparison of reported drug exposure across species after oral administration of molnupiravir indicated that the antiviral efficacy of the dose recommended for human use was underestimated in some animal models and overestimated in others. Frequently, molnupiravir was given prophylactically or shortly after SARS-CoV-2 inoculation in these models, in contrast to clinical trials where such timing is not consistently achieved. Furthermore, the recommended five-day treatment duration for humans was exceeded in several animal studies. Collectively, we suggest that design elements in the animal studies under examination contributed to a preference favoring molnupiravir, and thus inflated expectations for its efficacy against COVID-19. Addressing these elements may offer strategies to enhance the clinical efficacy of molnupiravir for the treatment of COVID-19. Such strategies include dose increment, early treatment initiation, administration by inhalation, and use of the drug in antiviral combination therapy.

"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.

Disruptive mutations in the serotonin transporter associate serotonin dysfunction with treatment-resistant affective disorder.

Affective or mood disorders are a leading cause of disability worldwide. The serotonergic system has been heavily implicated in the complex etiology and serves as a therapeutic target. The serotonin transporter (SERT) is a major regulator of serotonin neurotransmission, yet the disease-relevance of impaired SERT function remains unknown. Here, we present the first identification and functional characterization of disruptive coding SERT variants found in patients with psychiatric diseases. In a unique cohort of 144 patients characterized by treatment-resistant chronic affective disorders with a lifetime history of electroconvulsive therapy, we identified two previously uncharacterized coding SERT variants: SERT-N217S and SERT-A500T. Both variants were significantly enriched in the patient cohort compared to GnomAD (SERT-N217S: OR = 151, P = 0.0001 and SERT-A500T: OR = 1348, P = 0.0022) and ethnicity-matched healthy controls (SERT-N217S: OR ≥ 17.7, P ≤ 0.013 and SERT-A500T: OR = ∞, P = 0.029). Functional investigations revealed that the mutations exert distinct perturbations to SERT function, but their overall effects converge on a partial loss-of-function molecular phenotype. Thus, the SERT-A500T variant compromises the catalytic activity, while SERT-N217S disrupts proper glycosylation of SERT with a resulting dominant-negative trafficking deficiency. Moreover, we demonstrate that the trafficking deficiency of SERT-N217S is amenable to pharmacochaperoning by noribogaine. Collectively, our findings describe the first disease-associated loss-of-function SERT variants and implicate serotonergic disturbances arising from SERT dysfunction as a risk factor for chronic affective disorders.

Safety and efficacy of lirentelimab in patients with refractory indolent systemic mastocytosis: a first-in-human clinical trial.

BACKGROUND: Indolent systemic mastocytosis (ISM) is characterized by excessive mast cell (MC) accumulation and MC-driven signs and symptoms. Currently used therapies are not approved and have limited efficacy. Lirentelimab (AK002) is a monoclonal antibody against sialic acid-binding immunoglobulin-like lectin (Siglec)-8 that inhibits MC activation. OBJECTIVES: To determine the safety, tolerability and efficacy of lirentelimab in reducing the symptoms of ISM. METHODS: At a specialty centre for mastocytosis in Germany, we conducted a phase I first-in-human single-ascending and multidose clinical trial of lirentelimab in patients with ISM. Eligible adults had World Health Organization-confirmed ISM and an unsatisfactory response to available treatment. In part A, patients received a single dose of lirentelimab 0.0003, 0.001, 0.003, 0.01 or 0.03 mg kg-1; in part B, patients received one lirentelimab dose of 0.3 mg kg-1 or 1.0 mg kg-1; and in part C, patients received either 1.0 mg kg-1 lirentelimab every 4 weeks for 6 months or ascending doses of lirentelimab (one dose of 1 mg kg-1 followed by five doses of 3-10 mg kg-1 every 4 weeks). The primary endpoint was safety/tolerability. Secondary endpoints included changes from baseline in Mastocytosis Symptom Questionnaire (MSQ), Mastocytosis Activity Score (MAS) and Mastocytosis Quality of Life Questionnaire (MC-QoL) scores at 2 weeks after the final dose. RESULTS: In 25 patients with ISM (13 in parts A + B and 12 in part C; median age 51 years, 76% female, median 4.6 years from diagnosis), the most common treatment-related adverse events (AEs) were feeling hot (76%) and experiencing a headache (48%). No serious AEs occurred. Median MSQ and MAS symptom severity scores in part C improved (vs. baseline) across all symptoms [MSQ: skin (38-56%), gastrointestinal (49-60%), neurological (47-59%), musculoskeletal (26-27%); MAS: skin (53-59%), gastrointestinal (72-85%), neurological (20-57%), musculoskeletal (25%)]. Median MC-QoL scores improved across all domains: symptoms (39%), social life/functioning (42%), emotions (57%) and skin (44%). CONCLUSIONS: Lirentelimab was generally well tolerated and improved symptoms and quality of life in patients with ISM. The therapeutic potential of lirentelimab should be considered for ISM.

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.

COVID-19 infection in patients on long-term home parenteral nutrition for chronic intestinal failure.

BACKGROUND AND AIMS: To investigate the incidence and the severity of COVID-19 infection in patients enrolled in the database for home parenteral nutrition (HPN) for chronic intestinal failure (CIF) of the European Society for Clinical Nutrition and Metabolism (ESPEN). METHODS: Period of observation: March 1st, 2020 March 1st, 2021. INCLUSION CRITERIA: patients included in the database since 2015 and still receiving HPN on March 1st, 2020 as well as new patients included in the database during the period of observation. Data related to the previous 12 months and recorded on March 1st 2021: 1) occurrence of COVID-19 infection since the beginning of the pandemic (yes, no, unknown); 2) infection severity (asymptomatic; mild, no-hospitalization; moderate, hospitalization no-ICU; severe, hospitalization in ICU); 3) vaccinated against COVID-19 (yes, no, unknown); 4) patient outcome on March 1st 2021: still on HPN, weaned off HPN, deceased, lost to follow up. RESULTS: Sixty-eight centres from 23 countries included 4680 patients. Data on COVID-19 were available for 55.1% of patients. The cumulative incidence of infection was 9.6% in the total group and ranged from 0% to 21.9% in the cohorts of individual countries. Infection severity was reported as: asymptomatic 26.7%, mild 32.0%, moderate 36.0%, severe 5.3%. Vaccination status was unknown in 62.0% of patients, non-vaccinated 25.2%, vaccinated 12.8%. Patient outcome was reported as: still on HPN 78.6%, weaned off HPN 10.6%, deceased 9.7%, lost to follow up 1.1%. A higher incidence of infection (p = 0.04), greater severity of infection (p < 0.001) and a lower vaccination percentage (p = 0.01) were observed in deceased patients. In COVID-19 infected patients, deaths due to infection accounted for 42.8% of total deaths. CONCLUSIONS: In patients on HPN for CIF, the incidence of COVID-19 infection differed greatly among countries. Although the majority of cases were reported to be asymptomatic or have mild symptoms only, COVID-19 was reported to be fatal in a significant proportion of infected patients. Lack of vaccination was associated with a higher risk of death.

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.

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.

Prevalence of sarcopenia in patients with chronic intestinal failure-how are SARC-F and the EWGSOP algorithm associated before and after a physical exercise intervention.

INTRODUCTION: Patients with chronic intestinal failure (IF) have a low degree of physical activity, decreased muscle mass, and decreased muscle strength, leading to a high risk of sarcopenia. We aimed to test the prevalence of sarcopenia by the use of SARC-F and EWGSOP and to investigate the association between the two at baseline and after 12 weeks of an exercise intervention. METHODS: Thirty-one patients with chronic IF completed 12 weeks of three weekly home-based individualized exercise sessions. Body composition was measured by bioimpedance analysis and physical function by handgrip strength (HGS) and timed up-and-go (TUG). Sarcopenia was assessed by SARC-F and EWGSOP. Multiple regression analysis was used to test for the association between the two tools. RESULTS: The prevalence of sarcopenia measured by EWGSOP was 59%. This prevalence did not change after the intervention. At baseline, 38.8% of patients were screened as at risk for sarcopenia by SARC-F. This decreased to 29.0% after the intervention (P < 0.001). A statistically significant increase was achieved in muscle mass (P = 0.017) and muscle mass index (P = 0.016). Furthermore, both TUG (P = 0.033) and HGS (P = 0.019) improved. CONCLUSIONS: Sarcopenia is prevalent in patients with chronic IF. EWGSOP finds more patients to be at risk of sarcopenia than SARC-F but was not sufficiently sensitive to measure changes induced by the physical intervention. The significant change in SARC-F may illustrate that patients, themselves, find an improvement in self-perceived health.
