Abstract
BACKGROUND Lung transplant (LTx) recipients who gain weight after transplantation may experience an upward shift in body mass index (BMI) that places them in the obese category. The incidence, risk factors, and impact on metabolic health and mortality of new-onset obesity have not been documented in the LTx setting. METHODS This single-center retrospective study included 564 LTx recipients. Individuals were stratified according to their BMI trajectories from pretransplant evaluation up to 10 y posttransplant. New-onset obesity was defined as a pretransplant BMI <30 kg/m2 and posttransplant BMI >30 kg/m2. The incidence, risk factors, and posttransplant diabetes mellitus, metabolic syndrome, and mortality of recipients with new-onset obesity were compared with those of nonobese (BMI <30 kg/m2, pre/post-LTx), consistently obese (BMI >30 kg/m2, pre/post-LTx), and obese recipients with weight loss (BMI >30 kg/m2 pre-LTx, BMI <30 kg/m2 post-LTx). RESULTS We found that 14% of recipients developed obesity after transplantation. Overweight individuals (odds ratio [OR]: 9.01; 95% confidence interval [CI] [4.86-16.69]; P < 0.001) and candidates with chronic obstructive pulmonary disease (OR: 6.93; 95% CI [2.30-20.85]; P = 0.001) and other diagnoses (OR: 4.28; 95% CI [1.22-14.98]; P = 0.023) were at greater risk. Multivariable regression analysis showed that new-onset obesity was associated with a greater risk of metabolic syndrome (hazard ratio: 1.70; 95% CI [1.17-2.46]; P = 0.005), but not of posttransplant diabetes mellitus, than nonobesity. Recipients with new-onset obesity had a survival comparable to that of consistently obese individuals. CONCLUSIONS A greater understanding of the multifaceted nature of post-LTx obesity may lead to interventions that are better tailored to the characteristics of these individuals.

Relationships of accelerometer-determined physical activity with obesity, hypertension, diabetes, dyslipidemia, and health-related quality of life in patients after liver transplantation. Clin Transplant 2020; 34:e14117.

Abstract
The contribution of physical activity (PA) to the prevention of metabolic abnormalities following liver transplantation (LT) has not been well documented. We aimed to assess PA in post-LT patients and to quantify its relationships with the development of postoperative metabolic abnormalities and health-related quality of life (HRQOL). We recruited 111 patients who had undergone LT ≥ 6 months previously. PA was measured by accelerometry, and HRQOL was evaluated using SF-8. PA was quantified as the number of steps per day, and the time spent performing moderate-to-vigorous PA and light PA per week. The prevalence of hypertension, diabetes, and dyslipidemia increased more than twofold following LT. The proportion of the participants with a sedentary lifestyle (<5000 steps/day) was 36%. Logistic regression analysis showed that postoperative hypertension and obesity were associated with preoperative body mass index and the number of steps taken (in 2000 steps/day increments). Preoperative diabetes was associated with obesity, and PA was associated with physical function-related HRQOL scores. Thus, increasing the number of steps taken per day has the potential to reduce hypertension and obesity, and PA could improve physical function-related HRQOL in patients following LT.

Abstract
Physical activity is reduced in patients with chronic pulmonary diseases. Activity monitors can measure physical activity objectively and accurately over prolonged periods of time. Research grade and commercially available devices, using accelerometer technology, are being increasingly used in clinical studies. Physical activity levels have been found to have a moderate to strong correlation with important measures such as pulmonary function, exercise capacity, quality of life, and mortality and hospitalizations in patients with COPD, interstitial lung disease, pulmonary arterial hypertension and cystic fibrosis. Their use as a clinical trial end-point and as a tool to augment rehabilitation efforts has also been explored in patients with COPD with variable results. Due to the ease of use, economic viability, widespread availability and good patient compliance, their use in adult and pediatric medicine is expanding. This narrative review summarizes the current evidence of use of activity monitors in COPD, interstitial lung disease, asthma, pulmonary arterial hypertension, cystic fibrosis and lung transplant patients for the purposes of prognostication, monitoring, outcome measures and intervention.

Abstract
BACKGROUND Although exercise capacity improves postheart transplantation (HTx), it remains unclear if the level of physical activity (PA) shows similar improvement. The purpose of this study was to (1) describe PA levels and (2) identify factors which may be associated with levels of PA post-HTx. METHODS A prospective observational cross-sectional study was conducted at a single center HTx outpatient clinic. Medically stable adult recipients 6 months or longer post-HTx were recruited. Physical activity level (PAL) and average daily time spent at least moderately active (≥3 metabolic equivalents) were estimated using a multisensor device. Factors investigated were demographic (age, sex, body mass index [BMI], time post-HTx, and reason for HTx), corticosteroid use, exercise capacity (6-min walk distance), and quadriceps muscle strength corrected for body weight (QS%). RESULTS The mean post-HTx time of the 75 participants was 9.2 ± 7.0 years (0.5-26 y). Twenty-seven (36%) participants were classified as extremely inactive (PAL, <1.40), 26 (34.6%) sedentary (1.40 ≤ PAL ≤ 1.69), and 22 (29.3%) active (PAL, ≥1.70). Multivariable analysis showed greater QS% (β = 0.004 (0.002-0.006) P = 0.001) to be independently associated with increased PAL. For increased time, 3 or more metabolic equivalents both greater QS% (β = 0.0164 [0.003-0.029]; P = 0.014) and lower BMI (β = -0.0626 [-0.115 to -0.0099]; P = 0.021) were independently associated. CONCLUSIONS The degree of observed sedentary behavior post-HTx is surprising, with the majority of participants not reaching levels of PA recommended for health benefits. QS% and BMI were the only factors found to be independently associated with estimates of PA. Further quality trials are required to demonstrate the long-term benefits of regular PA and investigate ways of increasing adherence to PA post-HTx.

Abstract
INTRODUCTION Six-minute walk distance (6MWD) is a widely used surrogate for exercise capacity in patients both pre- and post-lung transplant. Multiple factors have been suggested to influence exercise capacity. RESEARCH QUESTIONS This study sought to determine the change in exercise capacity over time and factors that influence long-term exercise capacity. DESIGN Data were collected prospectively on lung transplant recipients from 1 center. The 6MWD was measured preoperatively and at the 6- and 12-month clinic visits postoperatively. The Enright equation was used to calculate patients' percentage predicted 6MWD. The change in 6MWD over time was calculated, and multiple factors affecting 6MWD were analyzed, including predictors of 6MWD at 6 and 12 months posttransplant. RESULTS Sixty lung transplant recipients were enrolled. Significant improvement in 6MWD was found between pretransplant and hospital discharge and between hospital discharge and 6 months posttransplant. The percentage predicted 6MWD improved significantly from pretransplant to 6 months and to 12 months posttransplant. Factors associated with 6MWD were sex, diagnosis, graft type, and age. Factors predicting long-term exercise capacity included 6MWD at referral, pretransplant, and hospital discharge; pulmonary diagnosis; and type of transplant. CONCLUSION The 6MWD provided useful information about patients' exercise capacity during phases of lung transplantation. The percentage predicted for each patient was found to be a more valuable measure than absolute 6MWD. Intensive, individualized training posttransplant is essential to optimize exercise capacity for this population.

Abstract
Physical rehabilitation of lung transplant candidates and recipients plays an important in optimizing physical function prior to transplant and facilitating recovery of function post-transplant. As medical and surgical interventions in lung transplantation have evolved over time, there has been a demographic shift of individuals undergoing lung transplantation including older individuals, those with multiple co-morbidites, and candidates with respiratory failure requiring bridging to transplantation. These changes have an impact on the rehabilitation needs of lung transplant candidates and recipients. This review provides a practical approach to rehabilitation based on research and clinical practice at our transplant centre. It focuses on functional assessment and exercise prescription during an uncomplicated and complicated clinical course in the pre-transplant, early and late post-transplant periods. The target audience includes clinicians involved in pre- and post-transplant patient care and rehabilitation researchers.

Abstract
BACKGROUND In lung transplantation (LTx), patients with thoracic muscle sarcopenia may have to require longer to recovery. We measured thoracic muscle volume by using the cross sectional area (CSA) and assessed its effect on early outcomes after LTx. METHODS A retrospective analysis was conducted to evaluate the effect of thoracic sarcopenia in patients undergoing LTx between January 2010 and July 2015. The lowest CSA quartile (Q1) was defined as sarcopenia. RESULTS In total, 109 patients were enrolled. The mean CSA was 58.24±15.82 cm(2). Patients in the highest CSA quartile were more likely to be male (92.6% vs. 17.9%, P<0.001), older (55.2±10.1 vs. 43.2±14.9 years, P=0.001), to have a higher body mass index (BMI) (22.3±4.0 vs. 19.4±3.7 kg/m(2), P=0.007), and to have pulmonary fibrosis (85.2% vs. 35.7%, P=0.003) compared with the lowest CSA quartile. Early outcomes including ventilator support duration [32.9±49.2 vs. 24.5±39.9 days, P= not significant (ns)], intensive care unit (ICU) stay duration (28.4±43.7 vs. 24.4±35.9 days, P= ns) and hospital stay duration (61.4±48.2 vs. 50.8±37.2 days, P= ns) tended to be longer in Q1 than Q4, but the difference was not significant. However, the 1-year survival rate was better in Q1 compared with Q4 (66.6% vs. 46.0%, P=0.04). CONCLUSIONS Although patients with thoracic sarcopenia seem to require a longer post-operative recovery time after LTx, this does not compromise their early outcomes. By contrast, patients with larger thoracic muscle volume (Q4) showed poorer survival times.

Abstract
BACKGROUND Little is known of the early changes in physical activity after lung transplantation. OBJECTIVES The purposes of this study were: (1) to describe physical activity levels in patients up to 6 months following lung transplantation and (2) to explore predictors of the change in physical activity in that population. DESIGN This was a prospective cohort study. METHODS Physical activity (daily steps and time spent in moderate-intensity activity) was measured using an accelerometer before and after transplantation (at hospital discharge, 3 months, and 6 months). Additional functional measurements included submaximal exercise capacity (measured with the 6-Minute Walk Test), quadriceps muscle torque, and health-related quality of life (measured with the Medical Outcomes Study 36-Item Short-Form Health Survey 36 [SF-36] and the St George's Respiratory Questionnaire). RESULTS Thirty-six lung transplant recipients (18 men, 18 women; mean age=49 years, SD=14) completed posttransplant measurements. Before transplant, daily steps were less than a third of the general population. By 3 months posttransplant, the largest improvement in physical activity had occurred, and level of daily steps reached 55% of the general population. The change in daily steps (pretransplant to 3 months posttransplant) was inversely correlated with pretransplant 6-minute walk distance (r=-.48, P=.007), daily steps (r=-.36, P=.05), and SF-36 physical functioning (SF-36 PF) score (r=-.59, P=.0005). The SF-36 PF was a significant predictor of the change in physical activity, accounting for 35% of the variation in change in daily steps. LIMITATIONS Only individuals who were ambulatory prior to transplant and discharged from the hospital in less than 3 months were included in the study. CONCLUSIONS Physical activity levels improve following lung transplantation, particularly in individuals with low self-reported physical functioning. However, the majority of lung transplant recipients remain sedentary between 3 to 6 months following transplant. The role of exercise training, education, and counseling in further improving physical activity levels in lung transplant recipients should be further explored.

Abstract
Lung transplant candidates and recipients have significant impairments in skeletal muscle mass, strength and function--individual measures of sarcopenia. Skeletal muscle dysfunction has been observed in the pre-transplant and post-transplant period and could have an important effect on transplant outcomes. A systematic review was performed to characterize the techniques used to study sarcopenia and assess the level of impairment throughout the transplant process. Electronic databases were searched (inception to July 2013) for prospective studies measuring at least 1 element of sarcopenia (muscle mass, strength, or function) in lung transplant patients. Eighteen studies were included, and study quality was assessed using the Downs and Black scale. A variety of measurements were used to evaluate sarcopenia in 694 lung transplant patients. Muscle mass in 7 studies was assessed using bioelectrical impedance (n = 4), computed tomography or magnetic resonance imaging (n = 2), or skin folds (n = 1), and was significantly reduced. Quadriceps strength was examined in 14 studies with computerized dynamometer (n = 10) and hand-held dynamometer (n = 4). Quadriceps strength was reduced in the pre-transplant period (mean range, 49%-86% predicted; n = 455 patients), further reduced immediately after transplant (51%-72%, n = 126), and improved beyond 3 months after transplant (58%-101%, n = 164). Only 2 studies measured lower extremity function (sit-to-stand test). A multitude of measurement techniques have been used to assess individual measures of sarcopenia, with reduced muscle mass and quadriceps strength observed in the pre-transplant and post-transplant period. Further standardization of measurement techniques is needed to assess the clinical effect of sarcopenia in lung transplantation.

Abstract
The increasing rate of societal obesity is also affecting the transplant world through obesity in candidates and donors as well as its posttransplant repercussions. Being overweight and obese has been shown to have significant effects on both short- and long-term complications as well as patient and graft survival. However, much of the comorbidity can be controlled or prevented with careful patient selection and aggressive management. A team approach to managing obesity and its comorbidities both pre- and posttransplant is essential for successful transplant outcomes. Complicating understanding the results of obesity research is the inclusion different weight categories, use of listing vs transplant weights, patient populations large enough for statistical power, and changes in transplant management, especially immunosuppression protocols, anti-infection protocols, and operative techniques. Much more research is needed regarding many elements, including safe weight loss before transplantation, prevention of weight gain after transplant, genomic influences, and the role of bariatric surgery in the transplant process.

Abstract
Background Although current national data show improved graft and patient survival following lung transplant, the effects of several modifiable preexisting comorbid conditions on health-related quality of life after transplant have not been evaluated. This study examines the effects of 3 comorbid conditions present before lung transplant (reduced bone density, diabetes mellitus, and elevated body mass index) on health-related quality of life after lung transplant. Methods The Short Form 36 Health Survey was completed by 92 adult recipients at various times after lung transplant (mean, 41 months; range, 1–127 months). Multiple linear regression models that controlled for underlying disease, chronic rejection, and time after transplant tested the independent effects of the 3 pretransplant conditions on posttransplant health-related quality of life. Results The effects of pretransplant reduced bone density and diabetes mellitus were not statistically significant in these models. However, pretransplant body mass index had a significant negative effect (β = −.29, P = .007) on posttransplant physical health–related quality of life. Additionally, overweight status and obesity exerted comparable independent negative effects ( P = .01 and P = .03, respectively) on the physical function scale of the Short-Form 36 Health Survey compared with persons who were underweight or normal weight before transplant. Conclusions Reevaluation of elevated body mass index before transplant as a risk for reduced physical quality of life after lung transplant should be considered.
