[Approaches to the pre-operative functional assessment of patients with lung cancer and preoperative rehabilitation].
Charloux, A, Enache, I, Pistea, C, Olland, A
Revue des maladies respiratoires. 2020;(10):800-810
Abstract
Surgery is the best treatment for early lung cancer but requires a preoperative functional evaluation to identify patients who may be at a high risk of complications or death. Guideline algorithms include a cardiological evaluation, a cardiopulmonary assessment to calculate the predicted residual lung function, and identify patients needing exercise testing to complete the evaluation. According to most expert opinion, exercise tests have a very high predictive value of complications. However, since the publication of these guidelines, minimally-invasive surgery, sublobar resections, prehabilitation and enhanced recovery after surgery (ERAS) programmes have been developed. Implementation of these techniques and programs is associated with a decrease in postoperative mortality and complications. In addition, the current guidelines and the cut-off values they identified are based on early series of patients, and are designed to select patients before major lung resection (lobectomy-pneumonectomy) performed by thoracotomy. Therefore, after a review of the current guidelines and a brief update on prehabilitation (smoking cessation, exercise training and nutritional aspects), we will discuss the need to redefine functional criteria to select patients who will benefit from lung surgery.

Abstract
Brazier, J, Antrobus, M, Stebbings, GK, Day, SH, Callus, P, Erskine, RM, Bennett, MA, Kilduff, LP, and Williams, AG. Anthropometric and physiological characteristics of elite male rugby athletes. J Strength Cond Res 34(6): 1790-1801, 2020-This is the first article to review the anthropometric and physiological characteristics required for elite rugby performance within both rugby union (RU) and rugby league (RL). Anthropometric characteristics such as height and body mass, and physiological characteristics such as speed and muscular strength, have previously been advocated as key discriminators of playing level within rugby. This review aimed to identify the key anthropometric and physiological properties required for elite performance in rugby, distinguishing between RU and RL, forwards and backs and competitive levels. There are differences between competitive standards such that, at the elite level, athletes are heaviest (RU forwards ∼111 kg, backs ∼93 kg; RL forwards ∼103 kg, backs ∼90 kg) with lowest % body fat (RU forwards ∼15%, backs ∼12%; RL forwards ∼14%, backs ∼11%), they have most fat-free mass and are strongest (back squat: RU forwards ∼176 kg, backs ∼157 kg; RL forwards ∼188 kg, backs ∼168 kg; bench press: RU forwards ∼131 kg, backs ∼118 kg; RL forwards ∼122 kg, backs ∼113 kg) and fastest (10 m: RU forwards ∼1.87 seconds, backs ∼1.77 seconds; 10 m: RL forwards ∼1.9 seconds, backs ∼1.83 seconds). We also have unpublished data that indicate contemporary RU athletes have less body fat and are stronger and faster than the published data suggest. Regardless, well-developed speed, agility, lower-body power, and strength characteristics are vital for elite performance, probably reflect both environmental (training, diet, etc.) and genetic factors, distinguish between competitive levels, and are therefore important determinants of elite status in rugby.

Osteoporosis international : a journal established as result of cooperation between the European Foundation for Osteoporosis and the National Osteoporosis Foundation of the USA. 2019;(10):1911-1922
Abstract
Maintaining mobility is an important aspect of health and well-being in older men. This literature review describes several modifiable and nonmodifiable risk factors impacting bone, muscle, and joint health. Exercise and nutritional interventions may help to prevent the progressive deterioration in bones, muscles, and joints impacting mobility in later life. Limitations in mobility are increasingly recognized as a major public health problem due to an aging population and growing number of older individuals affected by disabling comorbidities. Despite increasing numbers and debilitating consequences, there are no guidelines providing recommendations on strategies to maintain mobility for healthy aging among older men. This narrative review aims to fill this literature gap. PubMed, Scopus, and Google Scholar databases were searched using predefined search terms. Primary studies, exploratory analyses, cross-sectional surveys, meta-analyses, evidence-based clinical reviews, and guidelines from nationally recognized societies focusing on mobility in older men and key elements including bone, muscle and joint health, and balance were selected. Several modifiable and nonmodifiable risk factors have been reported in the literature that impact bone, muscle, and joint health and predispose older men to falls and fractures. The most common conditions impacting bones, muscles, and joints are osteoporosis, sarcopenia, and osteoarthritis, respectively. In addition to being key contributors to disability in the elderly, these conditions are all associated with a higher mortality risk. Although more studies are required, current evidence supports the use of various nonpharmacological (mainly exercise and nutrition) and/or pharmacological treatment modalities to help prevent and/or reverse these conditions. Incorporating lifestyle interventions involving exercise and nutrition at a younger age can help prevent the age-related, progressive deterioration in bones, muscles, and joints that can reduce mobility in later life. Established barriers to physical activities (e.g., poor health, social isolation) in men are important to consider for optimizing outcomes.

Exercise Counteracts the Cardiotoxicity of Psychosocial Stress.
O'Keefe, EL, O'Keefe, JH, Lavie, CJ
Mayo Clinic proceedings. 2019;(9):1852-1864
Abstract
Physical inactivity and psychosocial stress are prevalent in residents of the United States. The purpose of this article is to review the interaction between these 2 conditions and examine the effects of exercise on stress and cardiovascular (CV) health. A query of scientific references between 1974 to 2018 was performed using the PubMed search engine accessing the MEDLINE database using the search terms psychosocial stress, CV disease (CVD), physical activity, exercise, cardiac rehabilitation, and team sports. Psychosocial stress is a strong independent risk factor for adverse CV events. Conversely, people who experience CV events subsequently have drastically elevated rates of new-onset mental health disorders, including depression and anxiety. Psychosocial stress and CVD often trigger self-reinforcing feedback loops that can worsen mental health and cardiac prognosis. Exercise predictably improves CV health and prognosis and also is effective at lowering levels of psychosocial stress. Group exercise in particular seems to provide social support while at the same time boosting fitness levels and, thus, may be the single most important intervention for patients with concomitant CVD and emotional stress. Collaborative physical activity, such as group exercise, team sports, interactive physical play, and cardiac rehabilitation programs, have the potential to improve mental health and CV prognosis.

Abstract
PURPOSE The number of pediatric cancer survivors has increased dramatically over recent decades. Prior studies involving pediatric cancer survivors have reported reduced physical activity and fitness levels. Thus, the aim of this meta-analysis was to synthesize previous findings on physical activity and fitness levels of pediatric cancer survivors, who had completed cancer treatment and are in complete remission compared with age-matched, non-athletic healthy controls with no history of cancer diagnosis. METHODS Three electronic databases (PubMed, Web of Science, and EBSCO) were searched using a combination of 24 terms. Observational studies examining the post-treatment physical activity and/or fitness levels of pediatric cancer survivors compared with that of non-cancer controls and published in peer-reviewed, English-language journals before August 22, 2018 were eligible. Random-effect models were used in Comprehensive Meta-Analysis software for effect-size estimations of eight studies for physical activity and eight for fitness. RESULTS The studies included a total sample of 2628; 1413 pediatric cancer survivors and 1215 non-cancer controls. Both physical activity and fitness were significantly lower in childhood cancer survivors than in non-cancer controls (g = - 0.889; 95% confidence interval [CI] = - 1.648 - 0.130; p = 0.022) and (g = - 1.435; 95% CI = - 2.615 - 0.225; p = 0.017), respectively, with high heterogeneity. CONCLUSIONS Pediatric cancer sequelae and its treatment may limit participation in physical activity and fitness activities by survivors of pediatric cancer. Accentuating the need to incorporate physical activity and fitness into treatment protocols and post-treatment recommendations may improve pediatric cancer survivors' health and well-being.
