Efficacy of interventions to alter measures of fat-free mass in people with COPD: a systematic review and meta-analysis. ERJ Open Res 2023; 9:00102-2023. [PMID: 37529637 PMCID: PMC10388177 DOI: 10.1183/23120541.00102-2023] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2023] [Accepted: 04/08/2023] [Indexed: 08/03/2023] Open
Abstract
Introduction Low fat-free mass (FFM) is linked to poor health outcomes in COPD, including impaired exercise tolerance and premature death. The aim of this systematic review was to synthesise evidence on the effectiveness of interventions for increasing FFM in COPD. Methods Searches of electronic databases (MEDLINE, Cochrane Library, Embase, Web of Science, Scopus) and trial registers (ClinicalTrials.gov) were undertaken from inception to August 2022 for randomised studies of interventions assessing measures of FFM in COPD. The primary outcome was change in FFM (including derivatives). Secondary outcomes were adverse events, compliance and attrition. Results 99 studies (n=5138 people with COPD) of 11 intervention components, used alone or in combination, were included. Exercise training increased mid-thigh cross-sectional area (k=3, standardised mean difference (SMD) 1.04, 95% CI 0.02-2.06; p=0.04), but not FFM (k=4, SMD 0.03, 95% CI -0.18-0.24; p=0.75). Nutritional supplementation significantly increased FFM index (k=11, SMD 0.31, 95% CI 0.13-0.50; p<0.001), but not FFM (k=19, SMD 0.16, 95% CI -0.06-0.39; p=0.16). Combined exercise training and nutritional supplementation increased measures related to FFM in 67% of studies. Anabolic steroids increased FFM (k=4, SMD 0.98, 95% CI 0.24-1.72; p=0.009). Neuromuscular electrical stimulation increased measures related to FFM in 50% of studies. No interventions were more at risk of serious adverse events, low compliance or attrition. Discussion Exercise training and nutritional supplementation were not effective in isolation to increase FFM, but were for localised muscle and index measures, respectively. Combined, exercise and nutritional supplementation shows promise as a strategy to increase FFM in COPD. Anabolic steroids are efficacious for increasing FFM in COPD.

Abstract
Long-term respirator users admitted to intensive care units need to be transferred to a respiratory care center (RCC) for weaning. It may cause malnutrition in critical care patients, which may manifest as a reduction in respiratory muscle mass, lower ventilatory capacity, and decreased respiratory tolerance. This study aimed to assess that if the patients' nutritional status were improved, it could help RCC patients to wean from respirators. All participants were recruited from the RCC of a medical foundation in the city and Taipei Tzu Chi Hospital. The indicators include serum albumin level, respirator detachment index, maximum inspiratory pressure (PImax), rapid shallow breathing index, and body composition measurements. We recorded the length of hospital stay, mortality, and RCW (respiratory care ward) referral rate for these participants and analyzed the differences in relevant research indicators between those who were and weren't weaned off. 43 of 62 patients were weaned from respirators, while 19 failed. The resuscitation rate was 54.8%. Patients with respirator weaning had a lower number of RCC admission days (23.1 ± 11.1 days) than respirator-dependent patients (35.6 ± 7.8 days, P < 0.05). The PImax of successfully weaned patients had a greater reduction (- 27.09 ± 9.7 cmH2O) than unsuccessful ones (- 21.4 ± 10.2 cmH2O, P < 0.05). The Acute Physiology and Chronic Health Evaluation II (APACHE II) scores of successfully weaned patients (15.8 ± 5.0) were lower than those who were not (20.4 ± 8.4, P < 0.05). There was no significant difference in serum albumin levels between the two groups. In the successfully weaned patients, the serum albumin concentration was increased from 2.2 ± 0.3 to 2.5 ± 0.4 mg/dL, P < 0.05. Improved nutritional status can help RCC patients to wean from respirators.

Abstract
Introduction: Muscle mass may be a better predictor of mortality than BMI in chronic obstructive pulmonary disease (COPD). Serum creatinine depends on muscle mass and renal function; low values may predict higher mortality. Objective: To determine whether there is an association between low serum creatinine and mortality in severe COPD. Methods: This is a retrospective study of serum creatinine values at admission and within the last year before admission. Outcomes measured were mortality at 30 days and one year after admission in patients with acute type 2 respiratory failure secondary to COPD, who were admitted over a one-year period to a respiratory ward (N = 130). The statistics were calculated using the chi-squared test. Results: There appears to be a significant relationship between the one-year pre-admission creatinine values and mortality at one year (p = 0.0003). Conclusions: The relationship with mortality appears to be stronger with pre-admission creatinine values rather than the admission values and appears to predict the patients at the highest risk of mortality one year after admission.

Abstract
Compromised nutritional status is associated with a poor prognosis in chronic obstructive pulmonary disease (COPD) patients. However, the impact of nutritional support in this group of patients is controversial. The present study systematically reviewed the effect of energy and or protein supplements or food fortification on anthropometry and muscle strength of COPD patients. We searched MEDLINE (PubMed), EMBASE, Cochrane Library and Scopus for all published randomised clinical trials without language restriction up to May 2021. Three reviewers performed study selection and data extraction independently. We judged the risk of bias by RoB 2 and the certainty of evidence by the GRADE approach. We included thirty-two randomised controlled trials and compiled thirty-one of them (1414 participants) in the random-effects model meta-analyses. Interventions were energy and/or protein oral nutritional supplements or food fortification added to the diet for at least one week. Pooled analysis revealed that nutritional interventions increased body weight (muscle circumference (MD) = 1·44 kg, 95 % CI 0·81, 2·08, I2 = 73 %), lean body mass (standardised mean difference (SMD) = 0·37; 95 % CI 0·15, 0·59, I2 = 46 %), midarm muscle circumference (MD = 0·29 mm2, 95 % CI 0·02, 0·57, I2 = 0 %), triceps skinfold (MD = 1·09 mm, 95 % CI 0·01, 2·16, I2 = 0 %) and handgrip strength (SMD = 0·39, 95 % CI 0·07, 0·71, I2 = 62 %) compared with control diets. Certainty of evidence ranged from very low to low, and most studies were judged with some concerns or at high risk of bias. This meta-analysis revealed, with limited evidence, that increased protein and/or energy intake positively impacts anthropometric measures and handgrip strength of COPD patients.

Abstract
Background The novel coronavirus has embarked on a global pandemic and severe mortality with limited access for its treatments and medications. For the lack of time, research, and enough efficacy, most vaccines are underdeveloped or unreachable to society. However, many recent studies suggest various alternative, complementary remedies for COVID-19, which are functional foods. This review provides an overview of how functional foods can play a great role through modulating the host immune system, generating antiviral activities, and synthesizing biologically active agents effective against the coronavirus. Main body This review article summarizes the natural defense mechanisms in tackling SARS-CoV-2 alongside conventional therapeutic options and their corresponding harmful side effects. By analyzing bioactive components of functional foods, we have outlined its different contributions to human health and its potential immunomodulatory and antiviral properties that can enhance resistivity to viral infection. Moreover, we have provided a myriad of accessible and cost-effective functional foods that could be further investigated to target specific key symptoms of COVID-19 infections. Finally, we have found various functional foods with potent bioactive compounds that can inhibit or prevent COVID-19 infections and disease progression. Short conclusion Numerous functional foods can help the body fight COVID-19 through several mechanisms such as the reduced release of pro-inflammatory cytokines, reduced expression of ACE2 receptors in cells, and inhibiting essential enzymes in SARS-CoV-2.

Abstract
Due to the high smoking rate in developing countries and the rising aging population in high-income countries, the global prevalence of chronic obstructive pulmonary disease (COPD), estimated to be 11.7%, is increasing and is the third-leading cause of mortality. COPD is likely to be present in elderly individuals with impaired gastro-enteric functions. Gastrointestinal congestion, dyspnea, and anxiety are pathophysiological characteristics of COPD, contributing to poor appetite, reduced dietary intake, and high-energy expenditure. These factors are implicated in the progression of malnutrition in COPD patients. Malnutrition is detrimental to lung functions and is associated with an increased risk of infection, exacerbation and mortality, and a longer duration of hospitalization. Therefore, nutritional support to treat malnutrition in COPD patients is very vital. Oral nutritional supplements (ONS) may hold the key to COPD treatment. To clarify this statement, we review current evidence for ONS in COPD patients to benefit from clinical outcomes.

Abstract
BACKGROUND Disease-related malnutrition has been reported in 10% to 55% of people in hospital and the community and is associated with significant health and social-care costs. Dietary advice (DA) encouraging consumption of energy- and nutrient-rich foods rather than oral nutritional supplements (ONS) may be an initial treatment. OBJECTIVES To examine evidence that DA with/without ONS in adults with disease-related malnutrition improves survival, weight, anthropometry and quality of life (QoL). SEARCH METHODS We identified relevant publications from comprehensive electronic database searches and handsearching. Last search: 01 March 2021. SELECTION CRITERIA Randomised controlled trials (RCTs) of DA with/without ONS in adults with disease-related malnutrition in any healthcare setting compared with no advice, ONS or DA alone. DATA COLLECTION AND ANALYSIS Two authors independently assessed study eligibility, risk of bias, extracted data and graded evidence. MAIN RESULTS We included 94, mostly parallel, RCTs (102 comparisons; 10,284 adults) across many conditions possibly explaining the high heterogeneity. Participants were mostly older people in hospital, residential care and the community, with limited reporting on their sex. Studies lasted from one month to 6.5 years. DA versus no advice - 24 RCTs (3523 participants) Most outcomes had low-certainty evidence. There may be little or no effect on mortality after three months, RR 0.87 (95% confidence interval (CI) 0.26 to 2.96), or at later time points. We had no three-month data, but advice may make little or no difference to hospitalisations, or days in hospital after four to six months and up to 12 months. A similar effect was seen for complications at up to three months, MD 0.00 (95% CI -0.32 to 0.32) and between four and six months. Advice may improve weight after three months, MD 0.97 kg (95% CI 0.06 to 1.87) continuing at four to six months and up to 12 months; and may result in a greater gain in fat-free mass (FFM) after 12 months, but not earlier. It may also improve global QoL at up to three months, MD 3.30 (95% CI 1.47 to 5.13), but not later. DA versus ONS - 12 RCTs (852 participants) All outcomes had low-certainty evidence. There may be little or no effect on mortality after three months, RR 0.66 (95% CI 0.34 to 1.26), or at later time points. Either intervention may make little or no difference to hospitalisations at three months, RR 0.36 (95% CI 0.04 to 3.24), but ONS may reduce hospitalisations up to six months. There was little or no difference between groups in weight change at three months, MD -0.14 kg (95% CI -2.01 to 1.74), or between four to six months. Advice (one study) may lead to better global QoL scores but only after 12 months. No study reported days in hospital, complications or FFM. DA versus DA plus ONS - 22 RCTs (1286 participants) Most outcomes had low-certainty evidence. There may be little or no effect on mortality after three months, RR 0.92 (95% CI 0.47 to 1.80) or at later time points. At three months advice may lead to fewer hospitalisations, RR 1.70 (95% CI 1.04 to 2.77), but not at up to six months. There may be little or no effect on length of hospital stay at up to three months, MD -1.07 (95% CI -4.10 to 1.97). At three months DA plus ONS may lead to fewer complications, RR 0.75 (95% CI o.56 to 0.99); greater weight gain, MD 1.15 kg (95% CI 0.42 to 1.87); and better global QoL scores, MD 0.33 (95% CI 0.09 to 0.57), but this was not seen at other time points. There was no effect on FFM at three months. DA plus ONS if required versus no advice or ONS - 31 RCTs (3308 participants) Evidence was moderate- to low-certainty. There may be little or no effect on mortality at three months, RR 0.82 (95% CI 0.58 to 1.16) or at later time points. Similarly, little or no effect on hospitalisations at three months, RR 0.83 (95% CI 0.59 to 1.15), at four to six months and up to 12 months; on days in hospital at three months, MD -0.12 (95% CI -2.48 to 2.25) or for complications at any time point. At three months, advice plus ONS probably improve weight, MD 1.25 kg (95% CI 0.73 to 1.76) and may improve FFM, 0.82 (95% CI 0.35 to 1.29), but these effects were not seen later. There may be little or no effect of either intervention on global QoL scores at three months, but advice plus ONS may improve scores at up to 12 months. DA plus ONS versus no advice or ONS - 13 RCTs (1315 participants) Evidence was low- to very low-certainty. There may be little or no effect on mortality after three months, RR 0.91 (95% CI 0.55 to 1.52) or at later time points. No study reported hospitalisations and there may be little or no effect on days in hospital after three months, MD -1.81 (95% CI -3.65 to 0.04) or six months. Advice plus ONS may lead to fewer complications up to three months, MD 0.42 (95% CI 0.20 to 0.89) (one study). Interventions may make little or no difference to weight at three months, MD 1.08 kg (95% CI -0.17 to 2.33); however, advice plus ONS may improve weight at four to six months and up to 12 months. Interventions may make little or no difference in FFM or global QoL scores at any time point. AUTHORS' CONCLUSIONS We found no evidence of an effect of any intervention on mortality. There may be weight gain with DA and with DA plus ONS in the short term, but the benefits of DA when compared with ONS are uncertain. The size and direction of effect and the length of intervention and follow-up required for benefits to emerge were inconsistent for all other outcomes. There were too few data for many outcomes to allow meaningful conclusions. Studies focusing on both patient-centred and healthcare outcomes are needed to address the questions in this review.

Abstract
BACKGROUND Low body mass index (BMI) is an important prognostic factor in chronic obstructive pulmonary disease (COPD). However, the prognostic value of longitudinal BMI change in COPD has not been well studied. OBJECTIVE We aimed to evaluate the association between longitudinal change of BMI and prognosis of COPD in Korean COPD cohort. METHODS This study was conducted in a prospective Korean Obstructive Lung Disease (KOLD) cohort where COPD patients were recruited on an outpatient basis at 17 hospitals in South Korea. Annual BMI was measured over a period of 3 years or more. All patients were categorized into underweight (UW), normal weight (NW), and overweight (OW) groups by BMI. Clinical characteristics and outcomes including exacerbation and mortality were compared based on initial BMI grade and longitudinal change of BMI. RESULTS This analysis included 537 COPD patients (mean age = 67.4 ± 7.9 years, male = 97.0%, mean BMI = 23.0 ± 3.1) of KOLD cohort. The proportions of UW, NW, and OW groups were 6.9% (n = 37), 68.9% (n = 370), and 24.2% (n = 130) respectively. The UW group showed lower forced expiratory volume in 1 s (FEV1) (p < 0.001), shorter 6-minute walk distance (p < 0.001), higher modified Medical Research Council score (p = 0.002), higher St. George Respiratory Questionnaire score (p < 0.001), higher emphysema index (p < 0.001) and air-trapping index (p < 0.001), and more frequent (p < 0.001) and severe exacerbations (p = 0.003). Multivariable analyses demonstrated that decrease of BMI (hazard ratio [HR] = 0.786, p = 0.038) and the descent of BMI group (HR = 3.167, p = 0.016) at 3-year follow-up along with age, initial BMI, post-bronchodilator FEV1, and severe exacerbations were significantly associated with mortality. CONCLUSIONS This study demonstrated that BMI decrease during follow-up was independently associated with exacerbation and higher mortality of COPD, suggesting BMI reduction in COPD should be carefully managed.

Abstract
In the UK approximately 1.2 million people have COPD with around 25-40% being underweight and 35% have a severely low fat-free mass index. Measuring their body mass index is recommended and Health care professionals should endeavour to ensure that COPD patients are achieving their nutritional requirements. A narrative review summarizes evidence from 28 original articles identified through a systematic searches of databases, grey literature and hand searches covering 15 years, focusing on two themes, on the impact of malnutrition on COPD, and the management of malnutrition in COPD. Malnutrition causes negative effects on exercise and muscle function and lung function as well as increasing exacerbations, mortality and cost. Management options include nutritional supplementation which may increase weight and muscle function. Nutritional education has short-term improvements. Malnutrition affects multiple aspects of COPD, but treatment is of benefit. Clinical practice should include nutrition management.

Abstract
Chronic obstructive pulmonary disease (COPD) is a progressive lung disorder in which patients are at high risk for both pulmonary and systemic complications of their disease. Medical nutrition therapy by a registered dietitian nutritionist can be an integral component of lifestyle treatment targeted at maintaining and improving outcomes, such as lung function, mortality, and quality of life. The Academy of Nutrition and Dietetics (Academy) convened an expert workgroup to conduct a systematic review to update the COPD Evidence-Based Nutrition Practice Guideline. This publication outlines the Academy's Evidence Analysis Library methods used to complete the systematic review and guideline and examines the recommendations and supporting evidence. A total of 14 recommendations were developed based on evidence from eight conclusions. Using the Nutrition Care Process as a framework for practice, recommendations rated as strong included assessing and monitoring and evaluating body weight and medical nutrition therapy by a registered dietitian nutritionist. Weak recommendations included predicting resting and total energy expenditure. All other recommendations were rated as fair. These included individualizing the calorie prescription and macronutrient composition of the diet; assessing and monitoring and evaluating energy intake, serum 25-hydroxyvitamin D levels, and frequency of exacerbations; and determining need for vitamin D supplementation. Fewer than one-third of the systematic review's conclusions could be used to support the recommendations due to conflicting results or limited or no evidence available. The Evidence Analysis Library 2019 COPD Evidence-Based Nutrition Practice Guideline is a valuable resource for registered dietitian nutritionists and other health care professionals caring for those with COPD.

Abstract
Introduction Heart failure (HF), chronic obstructive pulmonary disease (COPD), and most chronic diseases are associated with mild to moderate chronic or recurrent inflammation. This inflammation contributes to malnutrition through different mechanisms: anorexia, decreased intake, alteration of metabolism with increased energy expenditure at rest and increased muscle catabolism. The decrease in lean mass has been included as a phenotypic criterion in the recently coined definition of malnutrition. In addition, a greater importance is given to the evaluation of the function, together with that of the morphological parameters. The grip strength, measured with a manual dynamometer and compared to reference populations, is a simple measure of muscle strength and correlates with the strength of the legs. On the other hand, the so-called "paradox of obesity" occurs in both patients with HF and COPD, since overweight and obese patients have lower overall mortality than patients with normal or low body mass index (BMI). The nutritional treatment, with an adequate contribution of macro and micronutrients and a contribution of proteins of fast absorption, with a higher content of leucine or its metabolite β-hydroxy-β-methylbutyrate, seems to offer a benefit in the preservation of muscle mass and its functionality in the patient with cardiorespiratory pathology. Nutritional treatment, associated with a pulmonary or cardiac rehabilitation regimen, is essential to obtain good morphological and functional results.

Abstract
Background Malnutrition is common in patients with COPD; however, little is known about its impacts on health-related quality of life (QoL) among patients with COPD. This study aimed to explore the nutritional status and dietary intake among outpatients with COPD in Vietnam and its possible associations with QoL. Methods A cross-sectional study was carried out in COPD outpatients visiting the COPD management unit at the National Lung Hospital, Hanoi, Vietnam between May 2017 and July 2017. Consecutive outpatients with a confirmed diagnosis of COPD were recruited with written inform consent. The nutritional status of participants was assessed using Subjective Global Assessment (SGA), and dietary intake via a 24-hour recall interview. The St George Respiratory Questionnaire (SGRQ) for COPD was used to investigate the participants’ QoL. Sociodemographic and clinical data were extracted from hospital records. Results Of 168 COPD outpatients involved in the study, three-quarters (74.4%) were diagnosed as malnourished (SGA B/C) and 81.5% reported unintentional weight loss. Most of the patients did not meet their estimated energy and protein requirements (85.7% and 89.9%, respectively). Malnutrition was significantly associated with disease severity (P=0.039) and ratio of protein intake to estimated requirement (P=0.005). QoL was low for all levels of malnutrition or disease severity, with well-nourished participants and those with less disease severity having better QoL (P=0.006 and P<0.001, respectively). With an extra meal per day, the odds of having malnutrition decreased 5.6 times (P<0.05) and the total SGRQ reduced 3.61 scores (P<0.05) indicating a better QoL. Conclusion Malnutrition and weight loss are prevalent among COPD outpatients. Most of the patients had inadequate dietary intake and low QoL. Nutrition counselling including increasing the number of meals per day with a focus on energy- and protein-rich foods may help improving nutritional status and QoL of patients with COPD in Vietnam.

Abstract
Malnutrition is one of the most important factors that lead to lower quality of
life in patients suffering from chronic obstructive pulmonary disease (COPD).
There are several methods for assessing malnutrition including anthropometric
indexes. The aim of this study was to determine the association of
anthropometric indexes with disease severity in male patients with COPD in
Qazvin, Iran. This cross-sectional study was conducted on 72 male patients with
COPD in Qazvin, Iran, from May to December 2014. Spirometry was performed for
all participants. Disease severity was determined using the Global Initiative
for Chronic Obstructive Lung Disease (GOLD) guideline. Body mass index (BMI),
mid-arm muscle circumference (MAMC), and triceps skinfold thickness (TSF) were
measured. MAMC and TSF were categorized into three subgroups as
<25th P, between 25th P and 75th P, and
>75th P (Where P is the abbreviation for percentile.). Data
were analyzed using ANOVA and logistic regression analysis. Mean age was 60.23 ±
11.39 years. Mean BMI was 23.23 ± 4.42 Kg/m2, mean MAMC was 28.34 ±
3.72 cm2, and mean TSF was 10.15 ± 6.03 mm. Mean BMI and MAMC in the
GOLD stage IV were significantly lower than other stages. Of 72, 18.1% were
underweight while 6.9% were obese. The GOLD stage IV was associated with 16
times increased risk of underweight and nine times increased risk of MAMC <
25th P. Disease severity was associated with BMI and MAMC as
indexes of malnutrition in patients with COPD in the present study. The GOLD
stage IV was associated with increased risk of underweight and low MAMC.

Abstract
INTRODUCTION A low body mass index (BMI) is associated with increased mortality and low health-related quality of life in patients with COPD. The Asia-Pacific classification of BMI has a lower cutoff for overweight and obese categories compared to the World Health Organization (WHO) classification. The present study assessed patients with COPD among different BMI categories according to two BMI classification systems: WHO and Asia-Pacific. PATIENTS AND METHODS Patients with COPD aged 40 years or older from the Korean COPD Subtype Study cohort were selected for evaluation. We enrolled 1,462 patients. Medical history including age, sex, St George's Respiratory Questionnaire (SGRQ-C), the modified Medical Research Council (mMRC) dyspnea scale, and post-bronchodilator forced expiratory volume in 1 second (FEV1) were evaluated. Patients were categorized into different BMI groups according to the two BMI classification systems. RESULT FEV1 and the diffusing capacity of the lung for carbon monoxide (DLCO) percentage revealed an inverse "U"-shaped pattern as the BMI groups changed from underweight to obese when WHO cutoffs were applied. When Asia-Pacific cutoffs were applied, FEV1 and DLCO (%) exhibited a linearly ascending relationship as the BMI increased, and the percentage of patients in the overweight and obese groups linearly decreased with increasing severity of the Global Initiative for Chronic Obstructive Lung Disease criteria. From the underweight to the overweight groups, SGRQ-C and mMRC had a decreasing relationship in both the WHO and Asia-Pacific classifications. The prevalence of comorbidities in the different BMI groups showed similar trends in both BMI classifications systems. CONCLUSION The present study demonstrated that patients with COPD who have a high BMI have better pulmonary function and health-related quality of life and reduced dyspnea symptoms. Furthermore, the Asia-Pacific BMI classification more appropriately reflects the correlation of obesity and disease manifestation in Asian COPD patients than the WHO classification.

Abstract
PURPOSE Chronic obstructive pulmonary disease (COPD) is often associated with malnutrition, which is in turn associated with poor outcomes. Accordingly, in COPD patients adequate nutrition might improve several clinical and functional outcomes. Nevertheless, information about nutrient intake of older populations with COPD is still scanty. MATERIALS AND METHODS We analysed data of 523 elderly attending a geriatric ambulatory. Of these, 165 had a diagnosis of COPD, while 358 were control participants, matched for demographic characteristics and free from respiratory diseases. COPD was diagnosed according to the global initiative for chronic obstructive lung disease (GOLD) criteria. The intake of micro and macronutrients was recorded using the European prospective investigation into cancer and nutrition (EPIC) questionnaire. Nutrient intake of COPD patients was compared with that of the control group and with recommended dietary allowances RDA. RESULTS COPD patients had a lower energy intake, as compared with control participants (29.4 vs 34.4 kcal/kg of ideal weight; P<.0001), due to reduced intake of carbohydrates and proteins. Accordingly, in the energy intake was lower than recommended in 52% of COPD patients, vs 30% of controls (P<.0001). The intake of calcium, potassium, folate, cholecalciferol, retinol, and thiamine was lower than RDA in over 75% of COPD patients. CONCLUSIONS The diet of elderly COPD outpatients does not provide the recommended energy intake, nor does it meet the RDA for many micronutrients. Such deficits are more severe than in age matched non- respiratory subjects.

Abstract
OBJECTIVES Diet modification may improve body composition and respiratory variables in children with respiratory insufficiency. Our objective was to examine the effect of an individualized diet intervention on changes in weight, lean body mass, minute ventilation, and volumetric CO2 production in children dependent on long-term mechanical ventilatory support. DESIGN Prospective, open-labeled interventional study. SETTING Study subjects' homes. PATIENTS Children, 1 month to 17 years old, dependent on at least 12 hr/d of transtracheal mechanical ventilatory support. INTERVENTIONS Twelve weeks of an individualized diet modified to deliver energy at 90-110% of measured energy expenditure and protein intake per age-based guidelines. MEASUREMENTS AND MAIN RESULTS During a multidisciplinary home visit, we obtained baseline values of height and weight, lean body mass percent by bioelectrical impedance analysis, actual energy and protein intake by food record, and measured energy expenditure by indirect calorimetry. An individualized diet was then prescribed to optimize energy and protein intake. After 12 weeks on this interventional diet, we evaluated changes in weight, height, lean body mass percent, minute ventilation, and volumetric CO2 production. Sixteen subjects, mean age 9.3 years (SD, 4.9), eight male, completed the study. For the diet intervention, a majority of subjects required a change in energy and protein prescription. The mean percentage of energy delivered as carbohydrate was significantly decreased, 51.7% at baseline versus 48.2% at follow-up, p = 0.009. Mean height and weight increased on the modified diet. Mean lean body mass percent increased from 58.3% to 61.8%. Minute ventilation was significantly lower (0.18 L/min/kg vs 0.15 L/min/kg; p = 0.04), and we observed a trend toward lower volumetric CO2 production (5.4 mL/min/kg vs 5.3 mL/min/kg; p = 0.06) after 12 weeks on the interventional diet. CONCLUSIONS Individualized diet modification is feasible and associated with a significant decrease in minute ventilation, a trend toward significant reduction in CO2 production, and improved body composition in children on long-term mechanical ventilation. Optimization of respiratory variables and lean body mass by diet modification may benefit children with respiratory insufficiency in the ICU.

Abstract
Diet and nutrition may be important modifiable risk factors for the development, progression and management of obstructive lung diseases such as asthma and chronic obstructive pulmonary disease (COPD). This review examines the relationship between dietary patterns, nutrient intake and weight status in obstructive lung diseases, at different life stages, from in-utero influences through childhood and into adulthood. In vitro and animal studies suggest important roles for various nutrients, some of which are supported by epidemiological studies. However, few well-designed human intervention trials are available to definitively assess the efficacy of different approaches to nutritional management of respiratory diseases. Evidence for the impact of higher intakes of fruit and vegetables is amongst the strongest, yet other dietary nutrients and dietary patterns require evidence from human clinical studies before conclusions can be made about their effectiveness.

Abstract
Introdução A redução da massa magra corpórea (MMC) é um fator independente de mortalidade em pacientes com Doença Pulmonar Obstrutiva Crônica (DPOC) e a literatura mostra que exercícios físicos aumentam a MMC. Objetivo Identificar fatores associados à melhora da composição corporal em indivíduos com DPOC após treinamento físico de alta intensidade. Métodos 37 pacientes com DPOC (19 H; 66 ± 7 anos; IMC = 27 ± 6 kg/m2; VEF1 = 38 ± 16 %pred) foram avaliados segundo sua composição corporal, função pulmonar, força muscular respiratória e periférica, capacidade funcional de exercício (teste de caminhada dos seis minutos, TC6M), nível de atividade física diária (DynaPort®), sensação subjetiva de dispneia (escala Medical Research Council) e qualidade de vida (Saint George Respiratory Questionnaire). O treinamento conteve exercícios de endurance e força muscular (3 vezes por semana por três meses). Após três meses, os pacientes foram reavaliados. Aqueles que apresentaram incremento de MMC incorporaram à estatística. Resultados No pré-treinamento, a MMC se correlacionou significativamente (p ≤ 0,05) com gasto energético total (r = 0,57), TC6M em %predito (r = 0,46), pressão expiratória máxima (PEmax) (r = 0,57), volume expiratório forçado no primeiro segundo em %predito (r = 0,47), força muscular de quadríceps femoral (r = 0,54), bíceps (r = 0,62) e tríceps braquial (r = 0,63). Contudo, o incremento da MMC após treinamento correlacionou-se significativamente somente com a melhora das escalas MRC (r = 0,4; p = 0,05) e PEmax (r = 0,35; p = 0,04). Conclusão Apesar de a MMC de pacientes com DPOC estar relacionada com a capacidade funcional de exercício, força muscular respiratória e periférica, obstrução pulmonar e gasto energético no pré-tratamento, a melhora da composição corporal está relacionada somente ao incremento da força muscular expiratória e sensação de dispneia após treinamento físico de alta intensidade.

Abstract
Chronic obstructive pulmonary disease (COPD) is a lung disease characterized by airway obstruction and inflammation but also accompanied by several extrapulmonary consequences, such as skeletal muscle weakness and osteoporosis. Skeletal muscle weakness is of major concern, since it leads to poor functional capacity, impaired health status, increased healthcare utilization, and even mortality, independently of lung function. Osteoporosis leads to fractures and is associated with increased mortality, functional decline, loss of quality of life, and need for institutionalization. Therefore, the presence of the combination of these comorbidities will have a negative impact on daily life in patients with COPD. In this review, we will focus on these two comorbidities, their prevalence in COPD, combined risk factors, and pathogenesis. We will try to prove the clustering of these comorbidities and discuss possible preventive or therapeutic strategies.

Abstract
Chronic obstructive pulmonary disease (COPD) is a chronic respiratory illness with a myriad of disabling symptoms and a decline in the functional parameters that affect the quality of life. The mortality and morbidity associated with severe COPD is high and the patients are mostly housebound and in need of continuous care and support. The uncertain nature of its prognosis makes the commencement of palliative care and discussion of end-of-life issues difficult even in the advanced stage of the disease. This is often compounded by inadequate communication and counseling with patients and their relatives. The areas that may improve the quality of care include the management of dyspnea, oxygen therapy, nutritional support, antianxiety, and antidepressant treatment, and advance care planning. Hence, it is necessary to pursue a holistic care approach for palliative care services along with disease-specific medical management in all such patients to improve the quality of life in end-stage COPD.

Abstract
Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory disorder of the lung and whole body caused mainly by tobacco smoking. Patients with advanced COPD are in a state of undernutrition, referred to as pulmonary cachexia; the exercise performance and quality of life (QOL) of these patients are deteriorated, the vital prognosis is unfavorable, and the medico-economic burden posed by poorly nourished COPD patients is high. The mainstays of COPD treatment are pharmacotherapy, mainly with bronchodilators, and non-pharmacotherapeutic approaches such as respiratory rehabilitation and nutrition counseling. Nutritional supplement therapy, consisting primarily of high calorie intake, has been demonstrated to be effective for maintaining and improving the muscle strength and exercise tolerance in poorly nourished COPD patients. The efficacy of intake of various nutrients, besides a high calorie intake, for amelioration of the disease state of COPD has also been reported. The roles of adipokines in the pathophysiology of COPD have begun to receive attention recently, and not only their regulatory effects on appetite and nutritional status, but also their influence on systemic inflammation have been increasingly clarified. We review the papers on COPD and nutrition and discuss the role of nutritional supplement therapy in the treatment of COPD.

Abstract
BACKGROUND Individuals with chronic obstructive pulmonary disease (COPD) and low body weight have impaired pulmonary status, reduced diaphragmatic mass, lower exercise capacity and higher mortality than those who are adequately nourished. Nutritional support may be useful for their comprehensive care. OBJECTIVES To assess the impact of nutritional support on anthropometric measures, pulmonary function, respiratory and peripheral muscles strength, endurance, functional exercise capacity and health-related quality of life (HRQoL) in COPD.If benefit is demonstrated, to perform subgroup analysis to identify treatment regimens and subpopulations that demonstrate the greatest benefits. SEARCH METHODS We identified randomised controlled trials (RCTs) from the Cochrane Airways Review Group Trials Register, a handsearch of abstracts presented at international meetings and consultation with experts. Searches are current to April 2012. SELECTION CRITERIA Two review authors independently selected trials for inclusion, assessed risk of bias and extracted the data. Decisions were made by consensus. DATA COLLECTION AND ANALYSIS We used post-treatment values when pooling the data for all outcomes, and change from baseline scores for primary outcomes. We used mean difference (MD) to pool data from studies that measured outcomes with the same measurement tool and standardised mean difference (SMD) when the outcomes were similar but the measurement tools different. We contacted authors of the primary studies for missing data.We established clinical homogeneity prior to pooling. We presented the results with 95% confidence intervals (CI) in the text and in a 'Summary of findings' table. MAIN RESULTS We included 17 studies (632 participants) of at least two weeks of nutritional support. There was moderate-quality evidence (14 RCTs, 512 participants, nourished and undernourished) of no significant difference in final weight between those who received supplementation and those who did not (MD 0.69 kg; 95% CI -0.86 to 2.24). Pooled data from 11 RCTs (325 undernourished patients) found a statistically significant weight gain (MD 1.65 kg; 95% CI 0.14 to 3.16) in favour of supplementation; three RCTs (116 mixed population) found no significant difference between groups (MD -1.28 kg; 95% CI -6.27 to 3.72). However, when analysed as change from baseline, there was significant improvement with supplementation: 14 RCTs (five of which had imputed SE), MD 1.62 kg (95% CI 1.27 to 1.96 ); 11 RCTs (malnourished), MD 1.73 kg (95% CI 1.29 to 2.17) and three RCTs (mixed), MD 1.44 kg (95% CI 0.68 to 2.19).There was low-quality evidence from five RCTs (six comparisons, 287 participants) supporting a significant improvement from baseline for fat-free mass/fat-free mass index (SMD 0.57; 95% CI 0.04 to 1.09), which was larger for undernourished patients (three RCTs, 125 participants; SMD 1.08; 95% CI 0.70 to 1.47). There was no significant change from baseline noted for adequately nourished patients (one RCT, 71 participants; SMD 0.27; 95% CI -0.20 to 0.73), or for a mixed population (two RCTs, 91 participants; SMD -0.05; 95% CI -0.76 to 0.65).There was moderate-quality evidence from two RCTs (91 mixed participants) that nutritional supplementation significantly improved fat mass/fat mass index from baseline (SMD 0.90; 95% CI 0.46 to 1.33).There was low-quality evidence (eight RCTs, 294 participants) of an increase in mid-arm muscle circumference change (MAMC; MD 0.29; 95% CI 0.02 to 0.57).There was low-quality evidence (six RCTs, 125 participants) of no significant difference in change from baseline scores for triceps measures (MD 0.54; 95% CI -0.16 to 1.24).There was low-quality evidence (five RCTs, 142 participants) of no significant difference between groups in the six-minute walk distance (MD 14.05 m; 95% CI -24.75 to 52.84), 12-minute walk distance or in shuttle walking. However, the pooled change from baseline for the six-minute walk distance was significant (MD 39.96 m; 95% CI 22.66 to 57.26).There was low-quality evidence (seven RCTs, 228 participants) that there was no significant difference between groups in the forced expiratory volume in one second (FEV(1); SMD -0.01; 95% CI -0.31 to 0.30) when measured in litres or percentage predicted.There was low-quality evidence (nine RCTs, 245 participants) of no significant between group difference in maximum inspiratory pressure (MIP; MD 3.54 cm H(2)O; 95% CI -0.90 to 7.99), but those who received supplementation had a higher maximum expiratory pressure (MEP; MD 9.55 cm H(2)O; 95% CI 2.43 to 16.68). For malnourished patients (seven RCTs, 189 participants), those with supplementation had significantly better MIP (MD 5.02; 95% CI 0.29 to 9.76) and MEP (MD 12.73; 95% CI 4.91 to 20.55).There was low-quality evidence (four RCTs, 130 participants) of no significant difference in HRQoL total score (SMD -0.36; 95% CI -0.77 to 0.06) when pooling results from both the St George's Respiratory Questionnaire (SGRQ) and the Chronic Respiratory Questionnaire (CRQ).Two trials (67 participants) used the SGRQ to measure individual domains of activity, impact and symptoms. At the end of treatment, the pooled total SGRQ score was both statistically and clinically significant (MD -6.55; 95% CI -11.7 to -1.41). The three RCTs (123 participants) that used the CRQ to measure the change in individual domains (dyspnoea, fatigue, emotion, mastery), found no significant difference between groups. AUTHORS' CONCLUSIONS We found moderate-quality evidence that nutritional supplementation promotes significant weight gain among patients with COPD, especially if malnourished. Nourished patients may not respond to the same degree to supplemental feeding. We also found a significant change from baseline in fat-free mass index/fat-free mass, fat mass/fat mass index, MAMC (as a measure of lean body mass), six-minute walk test and a significant improvement in skinfold thickness (as measure of fat mass, end score) for all patients. In addition, there were significant improvements in respiratory muscle strength (MIP and MEP) and overall HRQoL as measured by SGRQ in malnourished patients with COPD.These results differ from previous reviews and should be considered in the management of malnourished patients with COPD.

Abstract
Background The association between body mass index (BMI) and mortality in patients suffering from chronic obstructive pulmonary disease (COPD) has been a subject of interest for decades. However, the evidence is inadequate to draw robust conclusions because some studies were generally small or with a short follow-up. Methods We carried out a search in MEDLINE, Cochrane Central Register of Controlled Trials, and EMBASE database for relevant studies. Relative risks (RRs) with 95% confidence interval (CI) were calculated to assess the association between BMI and mortality in patients with COPD. In addition, a baseline risk-adjusted analysis was performed to investigate the strength of this association. Results 22 studies comprising 21,150 participants were included in this analysis. Compared with patients having a normal BMI, underweight individuals were associated with higher mortality (RR = 1.34, 95% CI = 1.01–1.78), whereas overweight (RR = 0.47, 95% CI = 0.33–0.68) and obese (RR = 0.59, 95% CI = 0.38–0.91) patients were associated with lower mortality. We further performed a baseline risk-adjusted analysis and obtained statistically similar results. Conclusion Our study showed that for patients with COPD being overweight or obese had a protective effect against mortality. However, the relationship between BMI and mortality in different classes of obesity needed further clarification in well-designed clinical studies.

Abstract
Severe acute respiratory failure requiring mechanical ventilation is one of the most frequent reasons for admission to the intensive care unit. Among the most frequent causes for admission are exacerbation of chronic obstructive pulmonary disease and acute respiratory failure with acute lung injury (ALI) or with criteria of acute respiratory distress syndrome (ARDS). These patients have a high risk of malnutrition due to the underlying disease, their altered catabolism and the use of mechanical ventilation. Consequently, nutritional evaluation and the use of specialized nutritional support are required. This support should alleviate the catabolic effects of the disease, avoid calorie overload and, in selected patients, to use omega-3 fatty acid- and antioxidant-enriched diets, which could improve outcome.

Abstract
BACKGROUND Elderly patients with chronic obstructive pulmonary disease (COPD) usually have a compromised nutritional status which is an independent predictor of morbidity and mortality. To know the Resting Energy Expenditure (REE) and the substrate oxidation measurement is essential to prevent these complications. This study aimed to compare the REE, respiratory quotient (RQ) and body composition between patients with and without COPD. METHODS This case-control study assessed 20 patients with chronic obstructive pulmonary disease attending a pulmonary rehabilitation program. The group of subjects without COPD (control group) consisted of 20 elderly patients attending a university gym, patients of a private service and a public healthy care. Consumption of oxygen (O₂) and carbon dioxide (CO₂) was determined by indirect calorimetry and used for calculating the resting energy expenditure and respiratory quotient. Body mass index (BMI) and waist circumference (WC) were also measured. Percentage of body fat (%BF), lean mass (kg) and muscle mass (kg) were determined by bioimpedance. The fat free mass index (FFMI) and muscle mass index (MMI) were then calculated. RESULTS The COPD group had lower BMI than control (p = 0.02). However, WC, % BF, FFMI and MM-I did not differ between the groups. The COPD group had greater RQ (p = 0.01), REE (p = 0.009) and carbohydrate oxidation (p = 0.002). CONCLUSIONS Elderly patients with COPD had higher REE, RQ and carbohydrate oxidation than controls.

Abstract
BACKGROUND The efficacy of nutritional support in the management of malnutrition in chronic obstructive pulmonary disease (COPD) is controversial. Previous meta-analyses, based on only cross-sectional analysis at the end of intervention trials, found no evidence of improved outcomes. OBJECTIVE The objective was to conduct a meta-analysis of randomized controlled trials (RCTs) to clarify the efficacy of nutritional support in improving intake, anthropometric measures, and grip strength in stable COPD. DESIGN Literature databases were searched to identify RCTs comparing nutritional support with controls in stable COPD. RESULTS Thirteen RCTs (n = 439) of nutritional support [dietary advice (1 RCT), oral nutritional supplements (ONS; 11 RCTs), and enteral tube feeding (1 RCT)] with a control comparison were identified. An analysis of the changes induced by nutritional support and those obtained only at the end of the intervention showed significantly greater increases in mean total protein and energy intakes with nutritional support of 14.8 g and 236 kcal daily. Meta-analyses also showed greater mean (±SE) improvements in favor of nutritional support for body weight (1.94 ± 0.26 kg, P < 0.001; 11 studies, n = 308) and grip strength (5.3%, P < 0.050; 4 studies, n = 156), which was not shown by ANOVA at the end of the intervention, largely because of bias associated with baseline imbalance between groups. CONCLUSION This systematic review and meta-analysis showed that nutritional support, mainly in the form of ONS, improves total intake, anthropometric measures, and grip strength in COPD. These results contrast with the results of previous analyses that were based on only cross-sectional measures at the end of intervention trials.

Abstract
Disease-related malnutrition is common, detrimentally affecting the patient and healthcare economy. Although use of high protein oral nutritional supplements (ONS) has been recommended to counteract the catabolic effects of disease and to facilitate recovery from illness, there is a lack of systematically obtained evidence to support these recommendations. This systematic review involving 36 randomised controlled trials (RCT) (n=3790) (mean age 74 years; 83% of trials in patients >65 years) and a series of meta-analyses of high protein ONS (>20% energy from protein) demonstrated a range of effects across settings and patient groups in favour of the high protein ONS group. These included reduced complications (odds ratio (OR) 0.68 (95%CI 0.55-0.83), p<0.001, 10 RCT, n=1830); reduced readmissions to hospital (OR 0.59 (95%CI 0.41-0.84), p=0.004, 2 RCT, n=546); improved grip strength (1.76 kg (95%CI 0.36-3.17), p<0.014, 4 RCT, n=219); increased intake of protein (p<0.001) and energy (p<0.001) with little reduction in normal food intake and improvements in weight (p<0.001). There was inadequate information to compare standard ONS (<20% energy from protein) with high protein ONS (>20% energy from protein). The systematic review and meta-analysis provides evidence that high protein supplements produce clinical benefits, with economic implications.

Abstract
BACKGROUND Disease-related malnutrition has been reported in 10% to 55% of people in hospital and the community. Dietary advice encouraging the use of energy- and nutrient-rich foods rather than oral nutritional supplements has been suggested as the initial approach for managing disease-related malnutrition. OBJECTIVES To examine evidence that dietary advice in adults with disease-related malnutrition improves survival, weight and anthropometry; to estimate the size of any additional effect of nutritional supplements combined with dietary advice and to compare the effects of dietary advice with oral nutritional supplements. SEARCH STRATEGY Relevant publications were identified from comprehensive electronic database searches and handsearching.Last search: 14 February 2010. SELECTION CRITERIA Randomised controlled trials of dietary advice with or without oral nutritional supplements in people with disease-related malnutrition in any health-care setting compared with no advice, oral nutritional supplements or dietary advice given alone. DATA COLLECTION AND ANALYSIS Two authors independently assessed trial eligibility, risk of bias and extracted data. MAIN RESULTS Forty-five studies (3186 participants) met the inclusion criteria; (dietary advice compared with: no advice (1053 participants); with oral nutritional supplements (332 participants); with dietary advice and oral nutritional supplements (731 participants); and dietary advice plus oral nutritional supplements compared with no additional intervention (1070 participants). Follow-up ranged from 18 days to 24 months. No comparison showed a significant difference between groups for mortality or morbidity. There was a significant change in weight found between groups when comparing dietary advice to no advice for interventions lasting greater than 12 months, mean difference 3.75 kg (95% confidence interval 0.97 to 6.53), and when all studies were combined, mean difference 1.47 kg (95% confidence interval 0.32 to 2.61) although there was significant heterogeneity in the combined analysis (I(2) = 90%). Similar improvements in weight were found for the comparison of dietary advice with nutritional supplements if required versus no advice, mean difference 2.20 kg (95% confidence interval 1.16 to 3.25). Dietary advice compared with no advice was also associated with significantly improved mid-arm muscle circumference when all studies were combined, but with moderate heterogeneity, mean difference 0.81 mm (95% confidence interval 0.31 to 1.31). Dietary advice given with nutritional supplements compared with dietary advice alone resulted in improvements in: mid-arm muscle circumference, mean difference -0.89 mm (95% confidence interval -1.35 to -0.43); triceps skinfold thickness, mean difference -1.22 mm (95% confidence interval -2.34 to -0.09); and grip strength, mean difference -1.67 kg (95% confidence interval -2.96 to -0.37), although the effects on triceps skinfold thickness and grip strength were heterogeneous. Dietary advice with supplements if required resulted in a significant increase in triceps skinfold thickness compared with no advice, mean difference 0.40 mm (95% confidence interval 0.10 to 0.70), although these results are from a single trial with only 29 participants. AUTHORS' CONCLUSIONS Evidence of variable quality suggests that dietary advice with or without oral nutritional supplements may improve weight, body composition and grip strength. We found no evidence of benefit of dietary advice or oral nutritional supplements given alone or in combination on survival. Studies addressing the impact of nutritional interventions on nutritional, functional and patient-centred outcomes are needed.

Abstract
Nutritional studies in patients with chronic obstructive pulmonary disease (COPD) are often based on oral nutritional supplementation and are of short duration. Our aim was to study the changes in body weight and physical performance in COPD patients after receiving the dietary advice for 1 year. Thirty-six patients with COPD as a primary diagnosis (mean age: 68.5±7.8 years), referred to a pulmonary rehabilitation program were studied. Each patient received dietary advice individually. Body weight had increased significantly by 1.3 kg (p=0.02) and walking distance by 83.2 m (p=0.007) after 1 year. There was an increase in mean handgrip strength after 1 year (1.6 kg, p=0.07). The mean intake of energy and protein expressed as percent of energy and protein requirement had increased after 1 year (15%, p<0.001, and 5.6%, p=0.09, respectively). Handgrip strength correlated significantly with energy (r=0.53, p=0.002), fat (r=0.50, p=0.02) and protein intake (r=0.41, p=0.002) after 1 year. In conclusion, positive effects on body weight, handgrip strength and walking distance in patients with COPD were seen after receiving dietary advice with a 1-year follow-up.

Abstract
Exacerbations contribute significantly to the morbidity of COPD, leading to an accelerated decline in lung function, reduced functional status, reduced health status and quality of life, poorer prognosis and increased mortality. Prevention of exacerbations is thus an important goal of COPD management. In patients with COPD, treatment with a combination of the inhaled corticosteroid fluticasone propionate (250 microg) and the long-acting beta(2)-agonist salmeterol (50 microg) in a single inhaler (250/50 microg) is an effective therapy option that has been shown to reduce the frequency of exacerbations, to improve lung function, dyspnea and health status, and to be relatively cost-effective as a COPD maintenance therapy. Importantly, results of various studies suggest that fluticasone propionate and salmeterol have synergistic effects when administered together that improve their efficacy in controlling symptoms and reducing exacerbations. The present non-systematic review summarizes the role of fluticasone propionate/salmeterol combination therapy in the prevention of exacerbations of COPD and its related effects on lung function, survival, health status, and healthcare costs.

Abstract
BACKGROUND Evidence for the effectiveness of nutritional supplements containing protein and energy, often prescribed for older people, is limited. Malnutrition is more common in this age group and deterioration of nutritional status can occur during illness. It is important to establish whether supplementing the diet is an effective way of improving outcomes for older people at risk from malnutrition. OBJECTIVES This review examined trials for improvement in nutritional status and clinical outcomes when extra protein and energy were provided, usually as commercial 'sip-feeds'. SEARCH STRATEGY We searched The Cochrane Library, MEDLINE, EMBASE, Healthstar, CINAHL, BIOSIS, CAB abstracts. We also hand searched nutrition journals and reference lists and contacted 'sip-feed' manufacturers. SELECTION CRITERIA Randomised and quasi-randomised controlled trials of oral protein and energy supplementation in older people, with the exception of groups recovering from cancer treatment or in critical care. DATA COLLECTION AND ANALYSIS Two reviewers independently assessed trials prior to inclusion and independently extracted data and assessed trial quality. Authors of trials were contacted for further information as necessary. MAIN RESULTS Sixty-two trials with 10,187 randomised participants have been included in the review. Maximum duration of intervention was 18 months. Most included trials had poor study quality. The pooled weighted mean difference (WMD) for percentage weight change showed a benefit of supplementation of 2.2% (95% confidence interval (CI) 1.8 to 2.5) from 42 trials. There was no significant reduction in mortality in the supplemented compared with control groups (relative risk (RR) 0.92, CI 0.81 to 1.04) from 42 trials. Mortality results were statistically significant when limited to trials in which participants (N = 2461) were defined as undernourished (RR 0.79, 95% CI 0.64 to 0.97).The risk of complications was reduced in 24 trials (RR 0.86, 95% CI 0.75 to 0.99). Few trials were able to suggest any functional benefit from supplementation. The WMD for length of stay from 12 trials also showed no statistically significant effect (-0.8 days, 95% CI -2.8 to 1.3). Adverse effects included nausea or diarrhoea. AUTHORS' CONCLUSIONS Supplementation produces a small but consistent weight gain in older people. Mortality may be reduced in older people who are undernourished. There may also be a beneficial effect on complications which needs to be confirmed. However, this updated review found no evidence of improvement in functional benefit or reduction in length of hospital stay with supplements. Additional data from large-scale multi-centre trials are still required.

Abstract
PURPOSE OF REVIEW Chronic obstructive pulmonary disease is the fifth leading cause of mortality in the world. This study reviews diet as a risk or protective factor for chronic obstructive pulmonary disease, mechanisms of malnutrition, undernutrition consequences on body functioning and how to modulate nutritional status of patients with chronic obstructive pulmonary disease. RECENT FINDINGS Different dietary factors (dietary pattern, foods, nutrients) have been associated with chronic obstructive pulmonary disease and the course of the disease. Mechanical disadvantage, energy imbalance, disuse muscle atrophy, hypoxemia, systemic inflammation and oxidative stress have been reported to cause systemic consequences such as cachexia and compromise whole body functioning. Nutritional intervention makes it possible to modify the natural course of the disease provided that it is included in respiratory rehabilitation combining bronchodilators optimization, infection control, exercise and, in some patients, correction of hypogonadism. SUMMARY Diet, as a modifiable risk factor, appears more as an option to prevent and modify the course of chronic obstructive pulmonary disease. Reduction of mechanical disadvantage, physical training and anabolic agents should be used conjointly with oral nutrition supplements to overcome undernutrition and might change the prognosis of the disease in some cases. Major research challenges address the role of systemic inflammation and the best interventions for controlling it besides smoking cessation.

Abstract
OBJECTIVE To investigate if handgrip strength (HGS) could be used as a single screening procedure in identifying patients who are classified as being undernourished or nutritionally-at-risk at hospital admission. DESIGN Cross-sectional study. In the second day of hospital admission, HGS was evaluated and results were compared with Nutritional Risk Screening (NRS-2002). SETTING Two public hospitals in Porto, Portugal, a university and a district one. SUBJECTS A probabilistic sample of 50% in-patients from each hospital of 314 patients (age range of 18-96) was studied. Patients were considered eligible if they were >or=18 years old and able to give informed consent. Hand pain, upper limb deformities, incapacity to perform muscle strength measurements and pregnancy were considered further exclusion criteria. RESULTS Patients identified as undernourished by NRS-2002 (37.9%) were older, shorter and lighter, with a lower functional capacity, a longer length of stay and a lower HGS (P<0.001). When comparing patients with lower HGS (first quartile) with those with the highest HGS (fourth quartile), this parameter revealed good sensitivity (86.7%) and specificity (70.2%) and a k=0.56. Multivariate analysis showed that patients with higher HGS had an independent decreased risk of being at nutritional risk (P for trend <0.001) odds ratio=0.19 (95% confidence interval=0.08-0.48). Our entire sample of hospitalized patients was -1.96 Z-score below the HGS cutoff of distribution data for healthy individuals. CONCLUSIONS HGS identifies a high proportion of nutritionally-at-risk patients and can be a reliable first screening tool for nutritional risk in hospitals.

Abstract
BACKGROUND Low body weight in patients with chronic obstructive pulmonary disease (COPD) is associated with an impaired pulmonary status, reduced diaphragmatic mass, lower exercise capacity and higher mortality rate when compared to adequately nourished individuals with this disease. Nutritional support may therefore be a useful part of their comprehensive care. OBJECTIVES To conduct a systematic review of randomised controlled trials (RCTs) to clarify whether nutritional supplementation (caloric supplementation for at least 2 weeks) improved anthropometric measures, pulmonary function, respiratory muscle strength and functional exercise capacity in patients with stable COPD. SEARCH STRATEGY Randomized controlled trials (RCTs) were identified from the Cochrane Airways Group register of RCTs, a hand-search of abstracts presented at international meetings and consultation with experts. Searches are current as of March 2004. SELECTION CRITERIA Two reviewers independently selected trials for inclusion, assessed quality and extracted the data. DATA COLLECTION AND ANALYSIS Within each trial and for each outcome, we calculated an effect size. The effect sizes were then pooled by a random-effects model. Homogeneity among the effect sizes was also tested. MAIN RESULTS Eleven studies recruiting 352 participants met the inclusion criteria. Eight papers were considered as high quality. Two studies were double-blinded. For each of the outcomes studied, the effect of nutritional support was small: the 95% confidence intervals around the pooled effect sizes all included zero. The effect of nutritional support was homogeneous across studies. AUTHORS' CONCLUSIONS Nutritional support had no significant effect on anthropometric measures, lung function or exercise capacity in patients with stable COPD.
