Effect of Macronutrients or Micronutrients Supplementation on Nutritional Status, Physical Functional Capacity and Quality of Life in Patients with COPD: A Systematic Review and Meta-Analysis. JOURNAL OF THE AMERICAN NUTRITION ASSOCIATION 2024:1-15. [PMID: 38329722 DOI: 10.1080/27697061.2024.2312852] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/17/2023] [Accepted: 01/25/2024] [Indexed: 02/09/2024]
Abstract
Given the importance that a correct and balanced nutrition has on patients with chronic obstructive pulmonary disease (COPD), supplementation of macro and micronutrients has been proposed, but the results of previous meta-analyses are contrasting. We performed an update of the latest evidence through a systematic review and meta-analysis of studies to assess the role of nutritional supplements in improving nutritional status, pulmonary function, physical performance, and quality of life of these patients.We included randomized controlled trials (RCTs) published between 01-01-2010 and 11-01-2023 evaluating the effectiveness of nutritional support in patients affected by stable COPD with an intervention of at least 2 weeks. Primary outcomes were changes in body mass index (BMI) and fat free mass index (FFMI). Secondary outcomes were exercise tolerance (6-min walking test, 6MWT), quality of life (St George's Respiratory Questionnaire, SGRQ) and respiratory function (FEV1). According with supplements type (macronutrients or micronutrients), we calculated the pooled adjusted mean difference (MD) and 95% confidence intervals (95%CIs) of the selected outcomes, using random-effects models in presence of high heterogeneity (I2>50%) or fixed-effects models otherwise. The risk of publication bias was evaluated with the trim and fill method.From 967 articles, 20 RCTs were included. Macronutrients supplementation improved BMI (MD 1.0 kg/m2, 95%CI 0.21-1.79), FFMI (MD 0.77 Kg/m2, 95%CI 0.48-1.06), 6MQT (MD 68.39 m, 95%CI 40.07-96.71), and SGRQ (MD -5.14, 95% CI -7.31-2.97), while it does not ameliorate respiratory function (MD 0.26% 95%CI -1.87-2.40). Micronutrients supplementation alone did not improve any of the considered outcomes.

Abstract
INTRODUCTION Chronic obstructive pulmonary disease (COPD) is a major cause of chronic morbidity and mortality worldwide. The coexistence of COPD and temporomandibular disorder (TMD) has been noted, and dysfunctional mastication resulting from TMD can worsen individuals' nutritional status. This association between COPD and TMD has been rarely discussed in previous studies. Therefore, this study aimed to determine whether osteoporosis increases the risk of TMD in COPD and whether anti-osteoporosis medications can prevent TMD. MATERIALS AND METHODS This retrospective nationwide population-based study utilized the Taiwan National Health Insurance Research Database. We enrolled 52,652 COPD patients between 2000 and 2015: 13,163 with osteoporosis and 39,489 without osteoporosis. Groups of COPD patients with and without osteoporosis were age- and sex-matched. A multivariable Cox proportional hazards regression model was used to evaluate the risk of TMD development in COPD patients with and without osteoporosis over 15 years. RESULTS There was a higher risk of TMD occurrence in COPD patients with osteoporosis than in those without osteoporosis (adjusted hazard ratio 2.564, P < 0.001) after adjusting for demographic variables and associative comorbidities. Osteoporosis, hypertension, vertebral compression fracture, and nonpsychotic mental disorders were risk factors contributing to TMD development in patients with COPD. Anti-osteoporosis medications were associated with the prevention of TMD development concomitant with osteoporosis and COPD (adjusted hazard ratio 0.617, P = 0.004). CONCLUSIONS Patients with COPD and osteoporosis are at a higher risk of developing TMD, and anti-osteoporosis medications can prevent the development of TMD in this context.

Abstract
Vertebral compression fracture (VCF) is a common comorbidity of chronic obstructive pulmonary disease (COPD), and the coexistence of COPD and temporomandibular disorder (TMD) has been clinically noted. The present study aimed to investigate whether VCF increases the risk of TMD in patients with COPD.With a follow-up period of 15 years, this retrospective, population-based longitudinal cohort study enrolled sex- and age-matched COPD patients with and without VCF (1:3) who were identified from Taiwan's National Health Insurance Research Database from 2000 to 2015. Multivariate Cox regression analysis was performed to determine the risk of TMD in COPD patients with and without VCF. The cumulative risk of TMD between groups was estimated using Kaplan-Meier analysis.The risk factors for TMD in patients with COPD were VCF, osteoporosis, and winter season. The COPD with VCF group was more likely to develop TMD (adjusted hazard ratio = 3.011, P < .001) than the COPD without VCF group after adjustment for sex, age, variables, and comorbidities. In the subgroup analysis, the COPD with VCF group had a higher risk of TMD than the COPD without VCF group in almost all stratifications.COPD patients with VCF are at a higher risk of developing TMD. Clinicians taking care of patients with COPD should be aware of the occurrence of TMD as a comorbidity.

Abstract
The relationship between pulmonary disease and nutrition is significant. Malnutrition and its associated adverse pulmonary effects can directly affect outcomes in the individual with pulmonary disease. The use of nutrition support is common for these patients as a supportive or therapeutic measure. Historical reports of adverse respiratory function associated with high parenteral carbohydrate intakes have led to the controversial use of high-fat enteral products in patients with chronic pulmonary dysfunction. The rationale for using this type of formula is that by providing less carbohydrates, carbon dioxide production will be reduced, respiratory quotient will therefore decrease, and a favorable respiratory outcome will result. In the patient with acute respiratory distress syndrome, an inflammatory state exists in which proinflammatory mediators are produced and affect the course of the disease. An enteral formula with modified lipids designed to modulate eicosanoid production and therefore influence the inflammatory cascade is available. This article reviews the rationale for use of modified enteral formulas in both chronic and acute pulmonary disease, reviews the available studies evaluating the efficacy of these formulas, and provides overall recommendations for the use of specialized enteral formulas in individuals with pulmonary disease.

Abstract
Androgens are mainly prescribed to treat several diseases caused by testosterone deficiency. However, athletes try to promote muscle growth by manipulating testosterone levels or assuming androgen anabolic steroids (AAS). These substances were originally synthesized to obtain anabolic effects greater than testosterone. Although AAS are rarely prescribed compared to testosterone, their off-label utilization is very wide. Furthermore, combinations of different steroids and doses generally higher than those used in therapy are common. Symptoms of the chronic use of supra-therapeutic doses of AAS include anxiety, depression, aggression, paranoia, distractibility, confusion, amnesia. Interestingly, some studies have shown that AAS elicited electroencephalographic changes similar to those observed with amphetamine abuse. The frequency of side effects is higher among AAS abusers, with psychiatric complications such as labile mood, lack of impulse control and high violence. On the other hand, AAS addiction studies are complex because data collection is very difficult due to the subjects' reticence and can be biased by many variables, including physical exercise, that alter the reward system. Moreover, it has been reported that AAS may imbalance neurotransmitter systems involved in the reward process, leading to increased sensitivity toward opioid narcotics and central stimulants. The goal of this article is to review the literature on steroid abuse and changes to the reward system in preclinical and clinical studies.

Abstract
BACKGROUND It is well documented that malnutrition is a common complication of paediatric malignancy and its treatment. Malnutrition can often be a consequence of cancer itself or a result of chemotherapy. Nutritional support aims to reverse malnutrition seen at diagnosis, prevent malnutrition associated with treatment and promote weight gain and growth. The most effective and safe forms of nutritional support in children and young people with cancer are not known. OBJECTIVES To determine the effects of any form of parenteral (PN) or enteral (EN) nutritional support, excluding vitamin supplementation and micronutrient supplementation, in children and young people with cancer undergoing chemotherapy and to determine the effect of the nutritional content of PN and EN. This is an update of a previous Cochrane review. SEARCH METHODS We searched the following databases for the initial review: CENTRAL (The Cochrane Library, Issue 2, 2009), MEDLINE (1950 to 2006), EMBASE (1974 to 2006), CINAHL (1982 to 2006), the National Research Register (2007) and Dissertations & Theses (2007). Experts in the field were also contacted for information on relevant trials. For this update, we searched the same electronic databases from 2006 to September 2013. We also scrutinised the reference lists of included articles to identify additional trials. SELECTION CRITERIA Randomised or quasi-randomised controlled trials comparing any form of nutritional support with another, or control, in children or young people with cancer undergoing chemotherapy. DATA COLLECTION AND ANALYSIS Two authors independently selected trials. At least two authors independently assessed quality and extracted data. We contacted trialists for missing information. MAIN RESULTS The current review included the eight trials from the initial review and six new trials which randomised 595 participants (< 21 years of age) with leukaemias or solid tumours undergoing chemotherapy. The trials were all of low quality with the exception of two of the trials looking at glutamine supplementation. One small trial found that compared to EN, PN significantly increased weight (mean difference (MD) 4.12, 95% CI 1.91 to 6.33), serum albumin levels (MD 0.70, 95% CI 0.14 to 1.26), calorie intake (MD 22.00, 95% CI 5.12 to 38.88) and protein intake (MD 0.80, 95% CI 0.45 to 1.15). One trial comparing peripheral PN and EN with central PN found that mean daily weight gain (MD -27.00, 95% CI -43.32 to -10.68) and energy intake (MD -15.00, 95% CI -26.81 to -3.19) were significantly less for the peripheral PN and EN group, whereas mean change in serum albumin was significantly greater for that group (MD 0.47, 95% CI 0.13 to 0.81, P = 0.008). Another trial with few participants found an increase in mean energy intake (% recommended daily amount) in children fed an energy dense feed compared to a standard calorie feed (MD +28%, 95% CI 17% to 39%). Three studies looked at glutamine supplementation. The evidence suggesting that glutamine reduces severity of mucositis was not statistically significant in two studies (RR 0.64, 95% CI 0.19 to 2.2 and RR 0.85, 95% CI 0.66 to 1.1) and differences in reduction of infection rates were also not significant in two studies (RR 1.0, 95% CI 0.72 to 1.4 and RR 0.98, 95% CI 0.63 to 1.51). Only one study compared olive oil based PN to standard lipid containing PN. Despite similar calorie contents in both feeds, the standard lipid formula lead to greater weight gain (MD -0.34 z-scores, 95% CI -0.68 to 0.00). A single study compared standard EN with fructooligosaccharide containing EN. There was no difference in weight gain between groups (mean difference -0.12, 95% CI -0.57 to 0.33), with adverse effects (nausea) occurring equally between the groups (RR 0.92, 95% CI 0.48 to 1.74). AUTHORS' CONCLUSIONS There is limited evidence from individual trials to suggest that PN is more effective than EN in well-nourished children and young people with cancer undergoing chemotherapy. The evidence for other methods of nutritional support remains unclear. Limited evidence suggests an energy dense feed increases mean daily energy intake and has a positive effect on weight gain. Evidence suggesting glutamine supplementation reduces incidence and severity of mucositis, infection rates and length of hospital stay is not statistically significant. Further research, incorporating larger sample sizes and rigorous methodology utilising valid and reliable outcome measures, is essential.

Abstract
BACKGROUND COPD is a leading cause of death and disability in the United States. Patients with COPD are at a high risk of nutritional deficiency, which is associated with declines in respiratory function, lean body mass and strength, and immune function. Although oral nutritional supplementation (ONS) has been associated with improvements in some of these domains, the impact of hospital ONS on readmission risk, length of stay (LOS), and cost among hospitalized patients is unknown. METHODS Using the Premier Research Database, we first identified Medicare patients aged ≥ 65 years hospitalized with a primary diagnosis of COPD. We then identified hospitalizations in which ONS was provided, and used propensity-score matching to compare LOS, hospitalization cost, and 30-day readmission rates in a one-to-one matched sample of ONS and non-ONS hospitalizations. To further address selection bias among patients prescribed ONS, we also used instrumental variables analysis to study the association of ONS with study outcomes. Model covariates included patient and provider characteristics and a time trend. RESULTS Out of 10,322 ONS hospitalizations and 368,097 non-ONS hospitalizations, a one-to-one matched sample was created (N = 14,326). In unadjusted comparisons in the matched sample, ONS use was associated with longer LOS (8.7 days vs 6.9 days, P < .0001), higher hospitalization cost ($14,223 vs $9,340, P < .0001), and lower readmission rates (24.8% vs 26.6%, P = .0116). However, in instrumental variables analysis, ONS use was associated with a 1.9-day (21.5%) decrease in LOS, from 8.8 to 6.9 days (P < .01); a hospitalization cost reduction of $1,570 (12.5%), from $12,523 to $10,953 (P < .01); and a 13.1% decrease in probability of 30-day readmission, from 0.34 to 0.29 (P < .01). CONCLUSIONS ONS may be associated with reduced LOS, hospitalization cost, and readmission risk in hospitalized Medicare patients with COPD.

Abstract
Chronic obstructive pulmonary disease (COPD) is an obstructive and progressive airway disease associated with an important reduction in daily physical activity and psychological problems that contribute to the patient's disability and poor health-related quality of life (HRQoL). Nowadays, pulmonary rehabilitation (PR) plays an essential role in the management of symptomatic patients with COPD, by breaking the vicious circle of dyspnea-decreased activity-deconditioning-isolation. Indeed the main benefits of comprehensive PR programs for patients with COPD include a decrease in symptoms (dyspnea and fatigue), improvements in exercise tolerance and HRQoL, reduction of health care utilization (particularly bed-days), as well as an increase in physical activity. Several randomized studies and meta-analyses greatly established the benefits of PR, which additionally, is recommended in a number of influential guidelines. This review aimed to highlight the impact of PR on COPD patients, focusing on the clinical usefulness of PR, which provides patients a good support for change.

Abstract
OBJECTIVE This manuscript summarizes the best available scholarly evidence related to anabolic-androgenic steroids (AAS) as a reference for health care professionals, including athletic trainers, educators, and interested others. BACKGROUND Health care professionals associated with sports or exercise should understand and be prepared to educate others about AAS. These synthetic, testosterone-based derivatives are widely abused by athletes and nonathletes to gain athletic performance advantages, develop their physiques, and improve their body image. Although AAS can be ergogenic, their abuse may lead to numerous negative health effects. RECOMMENDATIONS Abusers of AAS often rely on questionable information sources. Sports medicine professionals can therefore serve an important role by providing accurate, reliable information. The recommendations provide health care professionals with a current and accurate synopsis of the AAS-related research.

Abstract
INTRODUCTION: The individual with chronic obstructive pulmonary disease (COPD) can experience a significant reduction of body composition, peripheral muscle dysfunction, resulting in a negative influence on functional capacity. OBJECTIVES: To analyze the influence of body composition assessed by dual-energy x-ray absorptiometry on functional capacity of patients with chronic obstructive pulmonary disease (COPD). MATERIALS AND METHODS: Eleven male patients with COPD (COPDG), seven presenting moderate obstruction and four severe, and 11 sedentary male subjects (CG) were evaluated by dual-energy x-ray absorptiometry to assess their body composition. All subjects also performed the 6-minute walk test (6MWT) and Step Test (6MST) to assess their functional capacity. RESULTS: No significant differences were found between groups for anthropometric data such as age, weight, height and body mass index (BMI). However, the COPDG presented Forced Vital Capacity (FVC), Forced Expiratory Volume in one second (FEV1), FEV1/FVC ratio, Maximal Voluntary Ventilation (MVV), Walked Distance (WD) and Number of Steps (NS) significantly lower than the CG (p < 0.05, Student's t-test). The Body Bone Mass (BBM), BBM%, Lean Mass (LM), LM%, and Right Lower Limb (RLL) and Left Lower Limb (LLL) were significantly lower in the COPDG when compared with the CG, presenting statistically significant positive correlations with 6MWT's WD and 6MST's NS (p < 0.05, Pearson's test). CONCLUSION: We conclude that body composition is an important prognostic factor for patients with COPD, which reinforces the importance of assessing body composition by dual-energy absorptiometry since it has demonstrated with satisfactory accuracy in clinical practice. Moreover, it is a useful parameter for evaluation and reassessment in pulmonary rehabilitation programs.

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
Chronic obstructive pulmonary disease (COPD) is a progressive, chronic disease, in which malnutrition can have an undesirable effect. Therefore, the patient’s nutritional status is critical for optimizing outcomes in COPD. The initial nutrition assessment is focused on identifying calorically compromised COPD patients in order to provide them with appropriate nutrition. Nutritional intervention consists of oral supplementation and enteral nutrition to prevent weight loss and muscle mass depletion. Evaluation of nutritional status should include past medical history (medications, lung function, and exercise tolerance) and dietary history (patient’s dietary habits, food choices, meal patterns, food allergy information, and malabsorption issues), in addition to physiological stress, visceral proteins, weight, fat-free mass, and body mass index. The current medical literature conflicts regarding the appropriate type of formulation to select for nutritional intervention, especially regarding the amount of calories from fat to provide COPD patients. This review article focuses on the enteral product formulations currently available, and how they are most appropriately utilized in patients with COPD.

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 Malnutrition can often be a consequence of cancer itself or a result of chemotherapy. Nutritional support aims to reverse malnutrition seen at diagnosis, prevent malnutrition associated with treatment and promote weight gain and growth. The most effective and safe forms of nutritional support in children and young people with cancer are unclear. OBJECTIVES To determine the effects of any form of parenteral (PN) or enteral (EN) nutritional support in children and young people with cancer undergoing chemotherapy. SEARCH STRATEGY We searched the following databases: CENTRAL (The Cochrane Library 2009, Issue 2), MEDLINE (1950 to 2006), EMBASE (1974 to 2006), CINAHL (1982 to 2006), the National Research Register (2007) and Dissertations & Theses (2007). We scrutinised reference lists of articles to identify additional trials. We also contacted experts in the field for information on relevant trials. SELECTION CRITERIA Randomised or quasi-randomised controlled trials comparing any form of nutritional support with another, or control, in children or young people with cancer undergoing chemotherapy. DATA COLLECTION AND ANALYSIS Two authors independently selected trials. Three authors independently assessed quality and extracted data. We contacted trialists for missing information. MAIN RESULTS We included eight trials which randomised 159 participants (< 21 years) with leukaemias or solid tumours undergoing chemotherapy. The trials were all of low quality. One small trial found that compared to EN, PN significantly increased weight (mean difference (MD) 4.12; 95% CI 1.91 to 6.33), serum albumin levels (MD 0.70; 95% CI 0.14 to 1.26), calorie intake (MD 22.00; 95% CI 5.12 to 38.88) and protein intake (MD 0.80; 95% CI 0.45 to 1.15). One trial comparing peripheral PN and EN with central PN found that mean daily weight gain (MD -27.00; 95% CI -43.32 to -10.68) and energy intakes (MD -15.00; 95% CI -26.81 to -3.19) were significantly less for the peripheral PN and EN group, whereas mean change in serum albumin was significantly greater for that group(MD 0.47; 95% CI 0.13 to 0.81, P = 0.008). AUTHORS' CONCLUSIONS There is limited evidence from individual trials to suggest that parenteral nutrition is more effective than enteral nutrition in well-nourished children and young people with cancer undergoing chemotherapy. The evidence for other methods of nutritional support remains unclear. No studies were identified comparing the nutritional content in the PN or EN groups of studies. Further research, incorporating larger sample sizes and rigorous methodology utilising valid and reliable outcome measures, is essential.

Abstract
PURPOSE The purpose of this article is to provide a comprehensive review of the current modalities employed in diagnosing and treating chronic obstructive pulmonary disease (COPD). Special emphasis is placed on current guidelines, as defined by the Global Initiative for Chronic Obstructive Lung Disease. DATA SOURCE A comprehensive literature review for COPD serves as the basis for this article. CONCLUSIONS According to the National COPD Coalition (2004), there are nearly 24 million Americans who suffer from COPD. The incidence of COPD is rising globally and is associated with increased morbidity and mortality. COPD is characterized by progressive decline in function, resulting in concomitant diseases, which increase healthcare dollar expenditures, thus making COPD a concern for healthcare providers in the United States and abroad. IMPLICATIONS FOR PRACTICE Once a diagnosis of COPD is made, healthcare providers should explore multiple treatment options in an effort to find the most beneficial regimen. It is only when the treatments are individualized, including physiological therapies and cognitive approaches to lessen risks as well as to reduce exacerbations, that the patient with COPD is able to potentially experience a reasonable quality of life.

Abstract
Systemic inflammation is a recognized hallmark of chronic obstructive pulmonary disease pathogenesis. Although the origin and mechanisms responsible for the persistent chronic inflammatory process remain to be elucidated, it is recognized that it plays an important role in skeletal muscle pathology as observed in chronic obstructive pulmonary disease and several other chronic inflammatory disorders. This article describes state-of-the-art knowledge and novel insights in the role of inflammatory processes on several aspects of inflammation-related skeletal muscle pathology and offers new insights in therapeutic perspectives.

Abstract
BACKGROUND Pulmonary rehabilitation has become a standard of care for patients with chronic lung diseases. This document provides a systematic, evidence-based review of the pulmonary rehabilitation literature that updates the 1997 guidelines published by the American College of Chest Physicians (ACCP) and the American Association of Cardiovascular and Pulmonary Rehabilitation. METHODS The guideline panel reviewed evidence tables, which were prepared by the ACCP Clinical Research Analyst, that were based on a systematic review of published literature from 1996 to 2004. This guideline updates the previous recommendations and also examines new areas of research relevant to pulmonary rehabilitation. Recommendations were developed by consensus and rated according to the ACCP guideline grading system. RESULTS The new evidence strengthens the previous recommendations supporting the benefits of lower and upper extremity exercise training and improvements in dyspnea and health-related quality-of-life outcomes of pulmonary rehabilitation. Additional evidence supports improvements in health-care utilization and psychosocial outcomes. There are few additional data about survival. Some new evidence indicates that longer term rehabilitation, maintenance strategies following rehabilitation, and the incorporation of education and strength training in pulmonary rehabilitation are beneficial. Current evidence does not support the routine use of inspiratory muscle training, anabolic drugs, or nutritional supplementation in pulmonary rehabilitation. Evidence does support the use of supplemental oxygen therapy for patients with severe hypoxemia at rest or with exercise. Noninvasive ventilation may be helpful for selected patients with advanced COPD. Finally, pulmonary rehabilitation appears to benefit patients with chronic lung diseases other than COPD. CONCLUSIONS There is substantial new evidence that pulmonary rehabilitation is beneficial for patients with COPD and other chronic lung diseases. Several areas of research provide opportunities for future research that can advance the field and make rehabilitative treatment available to many more eligible patients in need.

Abstract
Emphysema is caused by exposure to cigarette smoking as well as alpha(1)-antitrypsin deficiency. It has been estimated to cost the National Health Service (NHS) in excess of 800 million pounds per year in related health care costs. The challenges for Critical Care nurses are those associated with dynamic hyperinflation, Auto-PEEP, malnutrition and the weaning from invasive and non-invasive mechanical ventilation. In this paper we consider the impact of the pathophysiology of emphysema, its effects on other body systems as well as the impact acute exacerbations have when patients are admitted to the Intensive Care Unit.

Abstract
BACKGROUND Quality of life has been found to be a significant predictor of survival in lung transplantation candidates. The aim of this study was to investigate associations between underweight, dietary support and well-being. METHODS A self-administered questionnaire for perceived well-being was administered to underweight (n=42) and normal-weight (n=29) candidates for lung transplantation before and after dietary intervention in which the underweight patients received dietary support for weight gain. RESULTS Underweight compared with normal-weight, independent of lung function, was associated with low well-being in several of the measured dimensions. Improvements were observed after dietary intervention compared with baseline in the underweight patients, for scores in the dimension of tiredness 29.2 (4.2) vs. 26.2 (6.0), P<0.01; general satisfaction 4.7 (1.5) vs. 4.0 (1.4), P=0.01; social life 16.7 (3.9) vs. 15.0 (4.4), P=0.02) (mean (sd) before and after dietary intervention respectively), but not in the normal-weight patients. The underweight patients achieved the goal for energy intake and protein intake and experienced a significant weight gain. Regression analyses showed that none of the well-being improvements was associated with weight gain or change in body composition. However, an association between less tiredness and an increase in protein intake was indicated (b=-0.305, P=0.055). CONCLUSION Underweight compared with normal-weight was associated with more impaired quality of life in candidates for lung transplantation and some benefit from dietary support in terms of well-being was indicated.

Abstract
A doença pulmonar obstrutiva crônica é progressiva e está relacionada a uma resposta inflamatória anormal dos pulmões à inalação de partículas e/ou gases tóxicos, sobretudo a fumaça de cigarro. Embora acometa primariamente os pulmões, diversas manifestações extrapulmonares relacionadas a esta enfermidade têm sido descritas. O aumento do número de células inflamatórias, que resulta em produção anormal de citocinas pró-inflamatórias, e o desequilíbrio entre a formação de radicais livres e a capacidade antioxidante, resultando em sobrecarga oxidativa, provavelmente são mecanismos envolvidos na inflamação local e sistêmica. Além disso, a diminuição do condicionamento físico secundária às limitações ventilatórias pode estar envolvida no desenvolvimento de alterações musculares. A doença pulmonar obstrutiva crônica apresenta diversas manifestações sistêmicas que incluem a depleção nutricional, a disfunção dos músculos esqueléticos, que contribui para a intolerância ao exercício, e as manifestações relacionadas a co-morbidades comumente observadas nestes pacientes. Essas manifestações têm sido relacionadas à sobrevida e ao estado geral de saúde dos pacientes. Nesse sentido, esta revisão tem como objetivo discutir os achados da literatura relacionados às manifestações sistêmicas da doença pulmonar obstrutiva crônica, ressaltando o papel da inflação sistêmica, e algumas perspectivas de tratamento.

Loss of body weight, as a result of imbalance between increased energy demand and/or reduced dietary intake, is a common problem in patients with COPD. The aim of this investigation was to examine the relationship between nutritional intake, change in body weight and the risk of exacerbation in patients with COPD. The study comprised 41 patients who were hospitalised because of an exacerbation of COPD. The follow-up period was 12 months. Weight, height and lung function were measured at baseline. At the 12-month follow-up, weight change and current weight were assessed by an interview and nutritional intake was recorded in a food diary for 7 days. An acute exacerbation was defined as having been admitted to hospital and/or making an emergency visit to hospital, due to COPD during the follow-up period. At baseline, 24% of the patients were underweight (body mass index (BMI)<20 kg/m2), 46% were of normal weight (BMI 20-25 kg/m2) and 29% were overweight (BMI>25 kg/m2). Energy intake was lower than the calculated energy demand for all groups. During the follow-up period, 24 of the 41 patients had an exacerbation. A low BMI at inclusion and weight loss during the follow-up period were independent risk factors for having an exacerbation (P=0.003 and 0.006, respectively). We conclude that, in patients who are hospitalised because of COPD, underweight and weight loss during the follow-up period are related to a higher risk of having new exacerbations.

Abstract
Pulmonary rehabilitation gradually has become the gold standard treatment for patients with severe lung disease, especially COPD. By definition, rehabilitation services are provided to patients with symptoms, most of whom have moderate-to-advanced lung disease. Because new therapeutic strategies, such as lung volume-reduction surgery and lung transplantation, require well-conditioned patients, pulmonary rehabilitation is becoming a crucial component of the overall treating strategy of many patients who heretofore were deemed untreatable. The positive results in several randomized trials have documented the effectiveness of pulmonary rehabilitation. Currently, pulmonary rehabilitation should be made available to all patients with symptomatic respiratory disease and be an integral part of any program considering high-risk surgery.

Abstract
STATE OF THE ART The IRAD2 trial is evaluating a 3-month home intervention which includes education, oral supplements, exercise and androgenic steroids in undernourished patients with chronic respiratory failure. The main objective is to increase the six-minute walking distance by more than 50 m with an improvement in health-related quality-of-life. Secondary end-points include a reduction in exacerbation rates by 25%, a reduction in health-related costs and an increase in survival during the year following intervention. MATERIAL AND METHODS This interventional, multi-centre, prospective, two-armed parallel, controlled trial is being conducted in 200 patients. In both groups, "Control" and "Rehabilitation", 7 home visits are scheduled during the 3-month intervention for education purpose. In the "Rehabilitation" group, patients will receive 160 mg/d of oral testosterone undecanoate in men, 80 mg/d in women, oral dietary supplements (563 kcal/d) and exercises on an ergometric bicycle 3 to 5 times a week. EXPECTED RESULTS In the event of significant responses to intervention, this trial would validate a comprehensive and global home-care for undernourished patients with chronic respiratory failure combining therapeutic education, oral supplements, androgenic substitution and physical activity.

Abstract
Chronic obstructive pulmonary disease (COPD) is a prevalent and serious condition. Nutrition might play a role in COPD prevention and is definitely important in COPD management. There are some indications from epidemiological studies that dietary factors such as ample consumption of fruit and fish may decrease COPD risk. The available evidence is, however, not substantial enough to warrant dietary recommendations for primary prevention of COPD. Substantial evidence does point to the conclusion that, regardless of disease severity, weight loss is related to decreased exercise capacity, health status and mortality as well as to increased morbidity among patients with moderate to severe COPD. Current nutritional support strategies have primarily focussed on treatment of severely underweight and disabled patients. In an in-patient setting or when incorporated in a pulmonary rehabilitation programme, nutritional support has proved effective in inducing weight gain and related functional improvements. However, such interventions are only feasible for a selected group of patients and are very laborious. Therefore, opportunities for dietary and nutrition interventions in COPD management should be explored, aiming at early detection, prevention and early treatment of involuntary weight loss. This means expanding the target group to include COPD out-patients and primary care patients before they have become underweight, and putting more emphasis on dietary change than on medically prescribed supplementation. Successful intervention assumes (voluntary) adjustment of dietary behaviour, and health professionals may play an essential role in encouraging patients to make and maintain these changes. Achieving dietary change among COPD patients may require a combination of diet counselling and self-management. A model for such a combination is presented.

Abstract
Chronic obstructive pulmonary disease (COPD) is a systemic disease with major impact worldwide. In the treatment of COPD a holistic approach should be taken. In order to reach this, an individual treatment plan should be made which includes at least elements of smoking cessation, optimisation of pulmonary status by pharmacotherapy and exercise embedded in a new lifestyle. Furthermore, more research on nutritional and metabolic intervention strategies for COPD patients is needed. With the availability of all these treatment options, a nihilistic attitude toward the patient with COPD is no longer justified.

Abstract
OBJECTIVES: To review the mechanisms involved in the origin of malnutrition in patients with chronic obstructive pulmonary disease (COPD), and to make a systematic review of randomized controlled studies, to clarify the contribution of nutritional supplementation in patients with stable COPD. METHOD: A systematic review of articles published in the field of nutrition, in any language and from several sources, including Medline, Embase, Cinahl, and the Cochrane Registry on COPD, as well as studies presented at congresses in the US and Europe. RESULTS: Studies on nutritional supplementation for more than two weeks showed a very small effect, not reaching statistical significance. A linear regression study found that old age, relative anorexia, and high inflammatory response are associated with non-response to nutritional therapy. CONCLUSION: Currently, there is no evidence that nutritional supplementation is truly effective in patients with COPD. Factors associated with non-response suggest a relationship with the degree of inflammation, including high TNF-alpha levels. Measuring inflammation markers may be useful to determine prognosis and adequate therapy. Treatment with anti-inflammatory cytokines or cytokine inhibitors seems promising for the future.

Abstract
Anabolic-androgenic steroids (AAS) are mainly used to treat androgen deficiency syndromes and, more recently, catabolic states such as AIDS-associated wasting. There is no evidence in the reviewed literature that AAS abuse or dependence develops from the therapeutic use of AAS. Conversely, 165 instances of AAS dependence have been reported among weightlifters and bodybuilders who, as part of their weight training regimens, chronically administered supraphysiologic doses, often including combinations of injected and oral AAS as well as other drugs of abuse. A new model is proposed in which both the "myoactive" and psychoactive effects of AAS contribute to the development of AAS dependence. The adverse consequences of AAS are reviewed, as well as their assessment by means of a history and physical, mental status examination, and laboratory testing. When patients with AAS use disorders are compared with patients with other substance use disorders, both similarities and differences become apparent and have implications for treatment.
