Abstract
OBJECTIVE Despite the availability of a wide range of oral nutritional supplements (ONS) offerings, individuals with malnutrition are still struggling to meet their nutritional targets. A new concentrated and high-protein energy-dense ONS (≥2.1 kcal/mL;32 g protein/200 mL) with high-quality protein (60% whey protein) has emerged as a pivotal formula to reach the patient's energy-protein requirements, enhance compliance, and maximize stimulation of muscle protein synthesis, key factors driving better nutritional, functional, and clinical outcomes. The purpose of this article is to provide our clinical experience using this new nutritionally concentrated ONS as a therapeutic strategy for patients with DRM. METHODS Three clinical cases have been examined using new assessment procedures and a new form of nutritional therapy, and their impact on the nutritional and functional outcomes in patients with moderate-to-severe DRM. RESULTS A tailored individualized nutritional interventions improved anthropometric, biochemical, and functional outcomes (Case 1,2, and 3) assessed using hand grip strength, bioimpedance and muscle ultrasound, and as well as good gastrointestinal tolerance (Case 1) and compliance to the ONS in patients with DRM (Case 1,2,3). CONCLUSION The use of this novel high-protein energy-dense formula with high-quality protein source (≥2.1 kcal/mL; 32 g protein/200 mL; 60% whey protein) overcome common practical challenges in the medical nutrition therapy of patients with DRM, either because these patients require a highly concentrated formulation to meet nutritional requirements due to loss of appetite, lack of interest in food, and high caloric-protein needs due to disease, and a large quantity and quality of protein to optimize muscle recovery due to sarcopenia, common in patients with moderate-severe malnutrition.

Multidimensional individualized nutritional therapy for individuals with severe chronic obstructive pulmonary disease: study protocol for a registry-based randomized controlled trial. Trials 2023; 24:86. [PMID: 36747276 PMCID: PMC9900973 DOI: 10.1186/s13063-023-07099-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2021] [Accepted: 01/06/2023] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND Individuals with severe chronic obstructive pulmonary disease (COPD) are often at risk of undernutrition with low health-related quality of life (HRQoL). Undernutrition can worsen COPD and other comorbidities, be an independent predictor of morbidity and functional decline resulting in increased healthcare consumption and increased risk of death. Especially exacerbations and acute infections result in unintentional weight loss. The aim is to investigate the effect of an individualized nutritional intervention among individuals with severe COPD. METHODS An open-label randomized controlled trial with two parallel groups. Participants are recruited from the pulmonary outpatient clinic at the Department of Pulmonary and Infectious Diseases, Copenhagen University Hospital, North Zealand, Denmark, and randomly allocated to either the intervention (intervention + standard of care) or control group (standard of care). The intervention has a duration of 3 months and combines individual nutritional care with adherence support and practical tools. It contains 4 elements including an individual nutritional plan, regular contacts, adherence support, and weight diary. The primary outcome is a difference in HRQoL (EQ-5D-5L) between the intervention and control group 3 months after baseline. Difference in functional capacity (grip strength, 30-s stand chair test, and physical activity), disease-specific quality of life (COPD Assessment Test), anxiety and depression (Hospital Anxiety and Depression Scale), nutritional parameters (energy and protein intake), anthropometry (weight, body mass index, waist, hip, and upper arm circumference), body composition (total fat-free and fat mass and indices), and prognosis (exacerbations, oxygen therapy, hospital contacts, and mortality) 3 months after baseline will be included as secondary outcomes. Data will be collected through home visits at baseline and 1 and 3 months after baseline. DISCUSSION Currently, nutritional care is a neglected area of outpatient care among individuals with severe COPD. If this patient-centered approach can demonstrate a positive impact on HRQoL, mortality, and hospital contacts, it should be recommended as part of end-of-life care for individuals with severe COPD.

Abstract
BACKGROUND Undernutrition, a common but treatable complication of chronic obstructive pulmonary disease (COPD), contributes to poor outcomes but is under-detected. Improved detection could prompt dietary intervention which may improve outcomes. We investigated whether adding a measure of muscle mass (fat-free mass index, FFMI) or a malnutrition screening tool (Mini Nutritional Assessment, MNA®) to the commonly used measure of body mass index (BMI), helps detect undernutrition in COPD. METHODS We conducted a retrospective chart review of 86 outpatients with COPD. Demographic and disease severity data were collected, and nutritional status assessed using BMI, FFMI and MNA®. RESULTS Patients comprised 55% males with median age 71.5 years, severe COPD (median FEV1 = 0.74 (30.5% predicted)) and high symptom impact (median COPD Assessment Test (CAT) = 23). Twenty-eight percent of patients had low BMI, 27% had low FFMI, 22% were MNA®-classified malnourished and 43% were MNA®-classified at risk of malnutrition. MNA® correlated moderately with BMI and classified 55% of patients with healthy/high BMI as either malnourished or at risk of malnutrition. FFMI and BMI correlated strongly, and low FFMI was present in 5% of patients with healthy/high BMI. The undernutrition measures also showed weak to moderate correlations with disease severity (spirometry data) and MNA® weakly correlated with symptom impact (CAT). CONCLUSION The MNA® identified more undernourished patients than FFMI or BMI. It also correlated with disease severity and broader symptom burden. The MNA® appears to be a simple tool for earlier detection of patients who may benefit from dietary intervention, potentially enhancing their quality of life.

AND-ASPEN and ESPEN consensus, and GLIM criteria for malnutrition identification in AECOPD patients: a longitudinal study comparing concurrent and predictive validity. Eur J Clin Nutr 2021; 76:685-692.

Abstract
BACKGROUND/OBJECTIVES Malnutrition in chronic obstructive pulmonary disease (COPD) patients is prevalent and usually assessed by body mass index (BMI), which can lead to misdiagnosis. The subjective global assessment (SGA) is the reference method for this diagnose in hospitalized patients. In the last decade, new tools have emerged Academy of Nutrition and Dietetics-American Society for Parenteral and Enteral Nutrition [AND-ASPEN], European Society for Clinical Nutrition and Metabolism [ESPEN], and Global Leadership Initiative on Malnutrition [GLIM]). Therefore, this study aimed to assess the concurrent and predictive validity of these tools in acute exacerbated COPD (AECOPD) patients. SUBJECTS/METHODS Prospective cohort study with hospitalized AECOPD patients. Malnutrition was diagnosed by SGA (reference method), AND-ASPEN, ESPEN, and GLIM consensus. Hospital length of stay (LOS) and mortality were the outcomes evaluated. RESULTS In 241 patients (46.5% males; 68.3 ± 10.2 years), malnutrition was found in 50.0% by SGA, 54.4% by AND-ASPEN, 20.2% by ESPEN, and 47.8% by GLIM. AND-ASPEN had the best accuracy (AUC = 0.837; 95% CI 0.783-0.841) and concordance (kappa = 0.674) with SGA and it was an independent predictor of prolonged LOS (OR = 1.73; 95% CI 1.01-3.37). ESPEN consensus did not agree with SGA, but was associated with prolonged LOS (OR = 2.57 95% CI, 1.27-5.20). The GLIM had good concordance (kappa = 0.533) and accuracy with SGA (AUC = 0.768; 95% CI 0.701-0.835), but was not associated with outcomes. CONCLUSIONS The AND-ASPEN was the most accurate tool for diagnosing malnutrition in AECOPD patients and was an independent predictor of prolonged LOS.

Abstract
BACKGROUND Muscle wasting is associated with worse outcomes in chronic obstructive pulmonary disease (COPD) patients. We assessed the association of calf circumference (CC) measurements with clinical outcomes in COPD patients referred to an outpatient pulmonary rehabilitation program (PRP). METHODS In this single-center, retrospective study, we analyzed demographic and clinical data ( spirometry tests, comorbidities, COPD exacerbations, dyspnea scoring, exercise capacity, quality-of-life scores, BMI, CC measurements, and all-cause deaths [for 2 years]) from COPD patients PRP medical records. Patients were grouped according to CC into reduced CC (male, ≤34 cm; female, ≤33 cm) or adequate CC groups. RESULTS We evaluated 144 patients (aged 64.6 ± 8.5 years; mostly males; forced expiratory volume in 1 s, 40.3% ± 15.8%, predicted). Eighteen patients (12.5%) died during the 2 years of follow-up. Logistic regression showed that patients with reduced CC were more likely to present worse outcomes compared with COPD patients with adequate CC: more advanced disease severity (odds ratio [OR] = 5.09; 95% CI, 2.00-12.96), COPD frequent exacerbators (OR = 2.34; 95% CI, 1.11-4.91), worse total quality-of-life score (OR = 2.70, 95% CI, 1.22-6.00), and higher mortality (OR = 3.69; 95% CI, 1.06-12.87). CONCLUSION Reduced CC in COPD patients under initial assessment for PRP admission was associated with disease severity, frequent exacerbation, poor health status, and higher mortality in 2 years of follow-up. Considering its clinical applicability, CC measurement should be introduced in the nutrition assessment of COPD patients admitted to the PRP.

Prevalence, associated factors, and prognostic value of sarcopenia in patients with acute exacerbated chronic obstructive pulmonary disease: A cohort study. Clin Nutr ESPEN 2021; 42:188-194. [PMID: 33745576 DOI: 10.1016/j.clnesp.2021.01.042] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2020] [Revised: 01/28/2021] [Accepted: 01/29/2021] [Indexed: 12/13/2022]
Abstract
BACKGROUND AND AIMS Besides pulmonary dysfunctions, patients with chronic obstructive pulmonary disease (COPD) also frequently have systemic comorbidities. Among these, sarcopenia is associated with worse pulmonary function and clinical outcomes. Patients with acute exacerbated COPD (AECOPD) have increased systemic inflammation, which can intensify muscle dysfunction. Therefore, the present study aimed to evaluate the prevalence of sarcopenia in AECOPD patients and assess the associated factors and their prognostic value. As a secondary aim, we also assessed the performance of calf circumference (CC) to diagnose this condition. METHODS Prospective cohort study in a Brazilian public hospital with AECOPD patients. Sarcopenia was assessed according to the recommendations from the European Working Group of Sarcopenia in Older People Consensus 2 (EWGSOP2); namely, reduced handgrip strength (HGS) combined with low fat-free mass index (FFMI) or CC. Data on clinical, nutritional, and sociodemographic features were collected. The evaluated clinical outcomes were the length of hospital stay (LOS), admission in intensive care units (ICUs), and in-hospital death. RESULTS Among 208 patients (54.8% females, 67.6 ± 10.1 years) evaluated, 16.3% presented sarcopenia. Malnutrition (odds ratio [OR] = 16.50, 95% confidence interval [CI] 3.58-76.08), and disease stages III-IV (OR = 4.05 95%CI 1.20-13.76) were associated with the presence of sarcopenia. The CC showed satisfactory performance in diagnosing sarcopenia as compared to FFMI as a marker of reduced muscle mass (kappa = 0.703; area under the receiver operating characteristic [AUC ROC] curve = 0.886; 95%CI 0.811-0.961). Sarcopenia was not associated with clinical outcomes. CONCLUSION Almost 20% of patients in this study presented sarcopenia. Malnutrition and advanced Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage were associated with increased chances of this condition in AECOPD patients. Reduced HSG combined with low CC may be an alternative when FFMI not be obtained for sarcopenia diagnosis.

Abstract
SARS-CoV-2 or COVID-19 is a novel coronavirus, which is the cause of the current pandemic with 107,411,561 infections and 2,351,195 death worldwide so far. There are multiple symptoms that are linked with the infection of COVID-19 such as coughing, shortness of breath, congestion together with fatigue, fever, loss of taste or smell, headaches, diarrhea, vomiting, and loss of appetite. The lack of or early stage of development of a cure for COVID-19 illness, there is need for insuring the best possible position of health to be able to fight the virus naturally through a robust immune system to limit severe complication. In this article, we have discussed the role of fruits and vegetables consumption to boost the immune system and major emphasis has been given to high risk group. We have taken into consideration a number of underlying conditions such as people with cardiovascular diseases, obesity, diabetes, chronic obstructive pulmonary disease, chronic kidney disease, hemoglobin disorder such as sickle cell disease, weakened immune system due to organ transplant. Furthermore, factors to improve the immune system, risks associated with quarantine and lifestyle and food handling during COVID-19 has been discussed.

Low Muscle Mass Is a Predictor of Malnutrition and Prolonged Hospital Stay in Patients With Acute Exacerbation of Chronic Obstructive Pulmonary Disease: A Longitudinal Study. JPEN J Parenter Enteral Nutr 2020; 45:1221-1230. [PMID: 32794593 DOI: 10.1002/jpen.1998] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2020] [Revised: 07/31/2020] [Accepted: 08/07/2020] [Indexed: 12/22/2022]
Abstract
BACKGROUND Malnutrition in chronic obstructive pulmonary disease (COPD) patients is more prevalent during times of exacerbation. Fat-free mass index (FFMI), calf circumference (CC), and adductor muscle pollicis thickness (AMPT) can be used to identify reduced muscle mass and have been found to be good predictors of clinical outcomes in other conditions, but they have not been investigated in COPD. Therefore, this study evaluated low muscle mass as predictor of malnutrition, prolonged length of stay (LOS), and in-hospital death in COPD patients. METHODS This prospective cohort study was carried out in hospitalized patients with COPD exacerbation. Malnutrition diagnosis was performed by Subjective Global Assessment, and muscle mass was assessed by FFMI, calculated using fat-free mass from bioelectrical impedance, CC, and AMPT. Clinical outcomes (LOS and in-hospital death) were collected from records. RESULTS One hundred seventy-six patients were included (68.2 ± 10.4 years old, 56.2% women); 74.2% were classified as Global Initiative of Chronic Obstructive Lung Disease 2 or 3 and 58.2% as malnourished. The median LOS was 11 (7-19) days, and the incidence of death was 9.1%. Low FFMI and CC predicted malnutrition (low CC: odds ratio [OR], 4.6; 95% CI, 2.2-9.7 and low FFMI: OR, 8.8; 95% CI, 3.7-20.8) and were associated with prolonged LOS (low CC: OR, 2.3; 95% CI, 1.1-4.6 and low FFMI: OR, 2.5; 95% CI, 1.3-4.8). CONCLUSION Simple, inexpensive, and noninvasive parameters of muscle mass-FFMI and CC-are good predictors of malnutrition and prolonged LOS in COPD patients experiencing exacerbation.
