Usefulness of the mini nutritional assessment short-form for evaluating nutritional status in patients with nontuberculous mycobacterial pulmonary disease: a prospective cross-sectional study. BMC Infect Dis 2024; 24:604. [PMID: 38898397 PMCID: PMC11186144 DOI: 10.1186/s12879-024-09499-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2024] [Accepted: 06/12/2024] [Indexed: 06/21/2024] Open
Abstract
BACKGROUND Although the Mini Nutritional Assessment (MNA) is recognized as a useful tool for evaluating nutritional status in patients with various diseases, its applicability in patients with nontuberculous mycobacterial pulmonary disease (NTM-PD) remains undetermined. METHODS We designed a prospective cross-sectional study to investigate whether the MNA Short-Form (MNA-SF) score can serve as a screening tool to assess the nutritional status of patients with NTM-PD. The MNA-SF was conducted upon patient enrollment, and correlation analyses were performed to compare MNA-SF scores with other nutritional measurements and disease severity. Multivariable logistic regression analyses were conducted to evaluate the association between MNA-SF scores and NTM-PD severity. RESULTS The 194 patients with NTM-PD included in the analysis had a median age of 65.0 (59.0-69.0) years; 59.3% (n = 115) had low MNA-SF scores (< 12). The low MNA-SF group exhibited a lower body mass index (19.7 vs. 22.4 kg/m2, p < 0.001) and fat-free mass index (14.7 vs. 15.6 kg/m2, p < 0.001) than the normal MNA-SF group, as well as higher incidences of sarcopenia (20.0% vs. 6.3%, p = 0.008) and adipopenia (35.7% vs. 5.1%, p < 0.001). However, no significant differences in calorie and protein intakes were observed between the two groups. Low MNA-SF scores were associated with radiographic severity (adjusted odds ratio 2.72, 95% confidence interval 1.38-5.36) but not with forced vital capacity. CONCLUSIONS The MNA-SF can effectively assess the nutritional status of patients with NTM-PD and can serve as an important clinical indicator in NTM-PD where treatment timing is determined by clinical judgment.

Abstract
The effectiveness of rehabilitation programs (RP) for chronic obstructive pulmonary disease (COPD) exacerbation remains controversial. However, few studies have investigated the combined effects of exercise and nutritional therapy. This study aimed to determine the effects of combined nutritional therapy on the physical function and nutritional status of patients with COPD exacerbation who underwent early RP. A randomized controlled trial was conducted in patients hospitalized for COPD exacerbations. Patients were assigned to receive a regular diet in addition to RP (control group) or RP and nutrition therapy (intervention group). Physical function, including quadricep strength and body composition, was assessed. The intervention group was administered protein-rich oral nutritional supplements. A total of 38 patients with negligible baseline differences were included in the analysis. The intervention group showed a notably greater change in quadriceps strength. Lean body mass and skeletal muscle indices markedly decreased in the control group but were maintained in the intervention group. Logistic regression analysis identified nutritional therapy as a significant factor associated with increased muscle strength. No serious adverse events were observed in either group. Therefore, nutritional therapy combined with RP is safe and effective for improving exercise function while maintaining body composition in patients with COPD exacerbation.

Abstract
OBJECT Malnutrition negatively affects patients with chronic obstructive pulmonary disease (COPD). This study aimed to explore the potential association between malnutrition, as defined by the Geriatric Nutritional Risk Index (GNRI), and all-cause mortality in patients with COPD using the National Health and Nutrition Examination Survey (NHANES). METHOD The data of 579 adults with COPD during NHANES 2013-2018 were analysed. Each patient was assigned to one of the two groups according to GNRI values: normal nutritional status (GNRI>98) and malnutrition status (GNRI≤98). Survival curves and Cox regressions were applied to evaluate the association between nutritional status and mortality. RESULTS Overall, the mean age was 63.4±0.5 years, and 53.9% of the patients were women. The prevalence of malnutrition was 6.6%, and the Kaplan-Meier curves for all-cause mortality according to nutritional status showed that malnutrition was associated with a higher incidence of all-cause mortality. The Cox regression analysis found that in the unadjusted model, the HR was 2.30 (95% CI 1.24 to 4.27, p=0.01). In the fully adjusted model, the adjusted HR was 2.47 (95% CI 1.36 to 4.5, p=0.003). Furthermore, subgroup analysis revealed that the risk of death due to malnutrition increased more than threefold in the low education and cancer subgroups. CONCLUSION A low GNRI was an independent risk factor for all-cause mortality in patients with COPD.

Prognostic Nutritional Index (PNI) as a Potential Prognostic Tool for Exacerbation of COPD in Elderly Patients. Int J Chron Obstruct Pulmon Dis 2023; 18:1077-1090.

Abstract
Purpose In COPD, exacerbation of the disorder causes a deterioration in the quality-of-life and worsens respiratory dysfunction, leading to a poor prognosis. In recent years, nutritional indices have been reported as significant prognostic factors in various chronic diseases. However, the relationship between nutritional indicators and prognosis in elderly subjects with COPD has not been investigated. Patients and methods We enrolled 91 subjects who received COPD assessment tests (CAT), spirometry, blood tests, and multidetector computed tomography (MDCT). We divided the subjects into two groups according to age (<75 years (n=57) and ≥ 75 years (n=34)). The prognostic nutritional index (PNI) was used to assess immune-nutritional status and was calculated as 10 x serum albumin + 0.005 x total lymphocyte count. We then examined the relationship between PNI and clinical parameters, including exacerbation events. Results There was no significant correlation between the PNI and CAT, the FEV1%pred, or low attenuation volume percentage (LAV%). In the elderly group, there were significant differences between the groups with or without exacerbation in the CAT and PNI (p=0.008, p=0.004, respectively). FEV1%pred, neutrophil-to-lymphocyte ratio (NLR) and LAV% did not differ between the two groups. The analytical model combining CAT and PNI improved the prediction of exacerbations in the elderly subjects (p=0.0068). Conclusion In elderly subjects with COPD, CAT were associated significantly with the risk of COPD exacerbation, with PNI also a potential predictor. The combined assessment of CAT and PNI may be a useful prognostic tool in subjects with COPD.

Abstract
BACKGROUND Physical activity is one of the most important prognostic factors for patients with chronic obstructive pulmonary disease (COPD). Physical activity correlates significantly with skeletal muscle mass and strength. Pulmonary rehabilitation has been conducted to improve physical activity, but its effectiveness has been inconsistent. Nutritional status is also related to physical activity in patients with COPD. The relationships between skeletal muscle mass, strength, and nutritional status evaluated using the Mini Nutritional Assessment Short Form (MNA-SF) were investigated. How nutritional status alters the relationships between physical activity, exercise capacity, skeletal muscle mass, and strength was also investigated. METHODS This retrospective, cross-sectional study enrolled 81 outpatients with COPD. In all patients, physical activity, exercise capacity, body composition assessment, and MNA-SF were assessed. The relationships between physical activity, exercise capacity, skeletal muscle mass, and strength were examined according to the MNA-SF. RESULTS The MNA-SF high group had significantly higher skeletal muscle mass than the MNA-SF low group when skeletal muscle strength was the covariate. In the MNA-SF low group, physical activity positively correlated with skeletal muscle mass. In the MNA-SF high group, physical activity positively correlated with skeletal muscle strength. CONCLUSIONS This study showed that the nutritional status of patients with COPD alters the relationship between physical activity and skeletal muscle mass or strength. Optimizing rehabilitation with nutrition interventions according to nutritional status might improve physical activity in patients with COPD.

Abstract
BACKGROUND Malnutrition is a significant comorbidity among chronic obstructive pulmonary disease (COPD), but it has been often ignored. To date, the prevalence of malnutrition and its association with clinical parameters in the patients with COPD have not been well described. We aimed to investigate the prevalence of malnutrition and the prevalence of at-risk for malnutrition among COPD and the clinical impact of malnutrition on patients with COPD in a systematic review and meta-analysis. METHODS PubMed, Embase, Cochrane Library, and Web of Science were searched for articles describing the prevalence of malnutrition and/or at-risk for malnutrition from January 2010 to December 2021. Eligibility screening, data extraction, and quality assessment of the retrieved articles were conducted independently by two reviewers. Meta-analyses were performed to determine the prevalence of malnutrition and at-risk for malnutrition and the clinical impact of malnutrition on patients with COPD. Meta-regression and subgroup analyses were performed to explore the sources of heterogeneity. Comparisons were made between individuals with and without malnutrition according to pulmonary function, degree of dyspnea, exercise capacity, and mortality risk. RESULTS Out of the 4156 references identified, 101 were read full-text, of which 36 studies were included. The total number of involved patients included in this meta-analysis was 5289. The prevalence of malnutrition was 30.0% (95% CI 20.3 to 40.6), compared with an at-risk prevalence of 50.0% (95% CI 40.8 to 59.2). Both prevalences were associated with regions and measurement tools. The prevalence of malnutrition was associated with COPD phase (acute exacerbations and stable). COPD with malnutrition showed lower forced expiratory volume 1 s % predicted (mean difference (MD) -7.19, 95% CI -11.86 to -2.52), higher modified Medical Research Council dyspnea scores (MD 0.38, 95% CI 0.12 to 0.64), poorer exercise tolerance (standardized mean difference -0.29, 95% CI -0.54 to -0.05), and higher mortality risk (hazard ratio 2.24, 95% CI 1.23 to 4.06) compared to COPD without malnutrition. CONCLUSION Malnutrition and at-risk for malnutrition are common among COPD. Malnutrition negatively impacts important clinical outcomes of COPD.

Abstract
Chronic Obstructive Pulmonary Disease (COPD) is a disease that is spreading worldwide and is responsible for a huge number of deaths annually. It is characterized by progressive and often irreversible airflow obstruction, with a heterogeneous clinical manifestation based on disease severity. Along with pulmonary impairment, COPD patients display different grades of malnutrition that can be linked to a worsening of respiratory function and to a negative prognosis. Nutritional impairment seems to be related to a reduced exercise tolerance and to dyspnoea becoming a major determinant in patient-perceived quality of life. Many strategies have been proposed to limit the effects of malnutrition on disease progression, but there are still limited data available to determine which of them is the best option to manage COPD patients. The purpose of this review is to highlight the main aspects of COPD-related malnutrition and to underline the importance of poor nutritional state on muscle energetics, exercise tolerance and dyspnoea.

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.

Abstract
The purpose of this study was to evaluate the association of serum lymphocyte level with several clinical parameters in COPD. The study population included 451 COPD patients from the Korean Obstructive Lung Disease cohort study. Serum lymphocyte level was measured every year along with various clinical parameters, such as lung function, 6-min walking (6 MW) distance, quality of life using COPD assessment test (CAT) and St. George's Respiratory Questionnaire (SGRQ) scores, exacerbations, and survival. Serum lymphocyte level less than 20% was considered as a low lymphocyte level. Normal lymphocyte and low lymphocyte groups comprised of 409 (90.7%) and 42 (9.3%) patients, respectively. Clustered analysis showed that patients in low lymphocyte group had a lower post-bronchodilator forced expiratory volume in 1 s % predicted (estimated mean = - 5.70%; P = 0.001), a lower forced vital capacity % predicted (estimated mean = - 5.63%; P = 0.005), a shorter 6 MW distance (estimated mean = - 41.31 m; P < 0.001), a higher CAT score (estimated mean = 2.62; P = 0.013), and a higher SGRQ score (estimated mean = 10.10; P < 0.001). Serum lymphocyte level was not associated with frequent acute exacerbations nor mortality. Low serum lymphocyte group showed poorer pulmonary function, lower 6 MW distance, and worse quality of life. Serum lymphocyte levels could be a simple and widely available predictive marker for variable clinical outcomes in COPD patients.

Health Lit Res Pract 2018; 2:e166-e174. [PMID: 31294292 PMCID: PMC6607835 DOI: 10.3928/24748307-20180803-01] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2018] [Accepted: 05/10/2018] [Indexed: 11/20/2022] Open
Abstract
Background: Nutrition literacy (NL) and food literacy (FL) have emerged as distinct forms of the multifaceted concept of health literacy (HL). Despite convincing evidence that changes in dietary behavior can improve health, the role of nutrition in supporting self-management in patients with chronic respiratory disease tends to be overlooked. Objective: This study examined patient and key informant (health care professionals, researchers, and policymakers) perspectives on nutrition in the context of self-management practices in asthma and chronic obstructive pulmonary disease with implications for NL and FL. Methods: Data were collected during 16 focus groups with 93 English- and French-speaking patients in the Canadian Provinces of British Columbia, Ontario, and Quebec, and in-depth interviews with 45 key informants mainly from Canada. Participants' comments, including dietary perception keywords, were extracted and classified using NVivo software. Thematic analysis was applied. Key Results: Patients' perspectives on nutrition reflected three broad themes: (1) importance of nutrition knowledge in self-management, (2) applying nutrition knowledge in self-management, and (3) challenges in applying nutrition knowledge in self-management. Embedded within the third theme were six sub-themes: Limitations in “accessing nutrition information,” “understanding nutrition information,” “basic literacy skills,” and “ability to act on nutrition information,” along with “lack of supports to act on nutrition information,” and “competing daily demands in mealtime and medication management.” Although less than 10% of key informants provided nutrition-relevant comments, their comments reinforced patients' concerns about barriers to accessing, understanding, and using nutrition information in self-management. Conclusions: Our findings suggest that more attention be directed to nutrition in the self-management of chronic respiratory disease and warrant further research on the roles of NL and FL in this health practice context. Such research could also contribute to the broader agenda of understanding NL and FL and applying them as subconcepts of HL in chronic disease self-management interventions. [HLRP: Health Literacy Research and Practice. 2018;2(3):e166–e174.] Plain Language Summary: Growing evidence supporting the role of diet in chronic disease calls for more attention to nutrition literacy. This study explored patient and key informant viewpoints on engaging with nutrition information in self-management of chronic lung disease. Findings suggest patients encounter many challenges in accessing, understanding, and acting on relevant nutrition information.

Redefining Cut-Points for High Symptom Burden of the Global Initiative for Chronic Obstructive Lung Disease Classification in 18,577 Patients With Chronic Obstructive Pulmonary Disease. J Am Med Dir Assoc 2018; 18:1097.e11-1097.e24. [PMID: 29169740 DOI: 10.1016/j.jamda.2017.09.003] [Citation(s) in RCA: 30] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2017] [Accepted: 09/07/2017] [Indexed: 11/19/2022]
Abstract
BACKGROUND Patients with chronic obstructive pulmonary disease (COPD) can be classified into groups A/C or B/D based on symptom intensity. Different threshold values for symptom questionnaires can result in misclassification and, in turn, different treatment recommendations. The primary aim was to find the best fitting cut-points for Global initiative for chronic Obstructive Lung Disease (GOLD) symptom measures, with an modified Medical Research Council dyspnea grade of 2 or higher as point of reference. METHODS After a computerized search, data from 41 cohorts and whose authors agreed to provide data were pooled. COPD studies were eligible for analyses if they included, at least age, sex, postbronchodilator spirometry, modified Medical Research Council, and COPD Assessment Test (CAT) total scores. MAIN OUTCOMES Receiver operating characteristic curves and the Youden index were used to determine the best calibration threshold for CAT, COPD Clinical Questionnaire, and St. Georges Respiratory Questionnaire total scores. Following, GOLD A/B/C/D frequencies were calculated based on current cut-points and the newly derived cut-points. FINDINGS A total of 18,577 patients with COPD [72.0% male; mean age: 66.3 years (standard deviation 9.6)] were analyzed. Most patients had a moderate or severe degree of airflow limitation (GOLD spirometric grade 1, 10.9%; grade 2, 46.6%; grade 3, 32.4%; and grade 4, 10.3%). The best calibration threshold for CAT total score was 18 points, for COPD Clinical Questionnaire total score 1.9 points, and for St. Georges Respiratory Questionnaire total score 46.0 points. CONCLUSIONS The application of these new cut-points would reclassify about one-third of the patients with COPD and, thus, would impact on individual disease management. Further validation in prospective studies of these new values are needed.
