Abstract
Recombinant erythropoietin (EPO) is used to correct for anaemia caused by chronic renal failure or cancer therapy. Improvement of the quality of life of anaemic patients treated with EPO was recently demonstrated and preliminary clinical results suggest an improvement of cognitive functions in patients receiving EPO. High expression of EPO and its receptor in the brain during embryonic development has led to the investigation of not only the neurotrophic role of EPO but also its neuroprotective properties. The neuroprotective effects of EPO have various complementary actions including antagonism of the effects of glutamate, increased expression of antioxidant enzymes, changes in production of neurotransmitters and induction of neuroglobin. Convincing experimental results suggest a blood-brain transport of EPO whereas clinical pharmacokinetic data do not as yet support this. The neuroprotective effects of EPO and its therapeutic promise need to be underlined.

Abstract
Glucocorticoids are among the most commonly used drugs. They are widely administered for acute and chronic musculoskeletal pain, as well as for several other pain syndromes, although their therapeutic use is sometimes diverted for doping purposes. Their time-course effects on hormonal and inflammatory responses nevertheless remain poorly understood, both at rest and during exercise. We therefore studied the alterations induced by 1 week of prednisone treatment (60 mg daily) in recreationally trained male athletes after 2 days (i. e., acute) and 7 days (i. e., short-term). Hormonal (i. e., DHEA, DHEA-S, aldosterone, and testosterone) and pro- and anti-inflammatory markers (i. e., IL-6, IL-10, and IL-1β) were investigated at rest and after resistance exercise. A significant decrease in DHEA and DHEA-S (p<0.01) without change in the DHEA/DHEA-S ratio, aldosterone, or testosterone was demonstrated after acute prednisone intake. A significant increment in IL-10 and a significant decrement in IL-6 (p<0.05) were also observed with prednisone both at rest and during exercise, without significant change in IL-1β. Continued prednisone treatment led to another significant decrease in both DHEA and DHEA-S (p<0.05), whereas no change in the inflammatory markers was observed between days 2 and 7. Our data demonstrate that the anti-inflammatory effects of prednisone were maximal and stable from the beginning of treatment, both in rest and exercise conditions. However, hormonal concentrations continued to decline during short-term intake. Further studies are needed to determine the effects of hormonal time-course alterations with longer glucocorticoid treatment and the clinical consequences.

Abstract
The dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEA-S) concentrations during acute and chronic exercise (training) have been investigated only fairly recently. DHEA is generally preferred to DHEA-S for exploring the acute exercise repercussions in laboratory or field tests because of its shorter elimination half-life. Conversely, DHEA-S is preferred to estimate chronic adaptations. Both can be measured noninvasively in saliva, and it is therefore possible to follow these hormone responses in elite athletes during competitive events and in healthy and pathological populations, without imposing additional stress. Indeed, the correlation between saliva and serum concentrations is high for steroid hormones, both at rest and during exercise. In this review, we will first summarize the current knowledge on the DHEA/DHEA-S responses to exercise and examine the potential modulating factors: exercise intensity, gender, age, and training. We will then discuss the ergogenic effects that athletes expect from the exogenous administration of DHEA and the antidoping methods of analysis currently used to detect this abuse.

Abstract
BACKGROUND The aim of this retrospective study was to assess the impact of a medical indoor environment counselor (MIEC) on the allergic child's indoor home environment, as well as the real-life experience of patients' families. METHODS We enrolled 50 children (age, 4-18 years) with allergic respiratory illness (96 % asthmatics) from March 2011 to January 2012. During the first visit, the CMEI gave advice according to the results of the assessment. Home environmental exposures were assessed 6 months later. A satisfaction questionnaire was completed by the parents. RESULTS We found a significant decrease in the presence of house dust mites (P = 0.0047), humidity, and molds (P = 0.0047) as well as volatile organic compounds (P = 0.0047). Smoking habits were not significantly changed (P = 0.083), nor was the presence of domestic pets (P = 0.3173). Over 74 % of the families were very satisfied with the CMEI's intervention. DISCUSSION According to de Blay's study, a home visit by the MEIC increased compliance with mite reduction. The intervention to advise parents of asthmatic children on the risks of passive smoking was ineffective in reducing their children's exposure to environmental tobacco smoke. The advice given by the MEIC was better understood by the patients than that expressed by the medical teams. CONCLUSION A targeted home-based environmental intervention increased the compliance to mite, humidity, and mold reduction. The role of the CMEI will undoubtedly develop: follow-up studies are necessary to justify their activity (cost-efficacy ratio of their intervention).

Abstract
Significant alteration in hypothalamic-pituitary-adrenal function has been demonstrated in patients after short-term glucocorticoid therapy, but its impact on the circadian rhythm of steroid hormones has never been investigated. This study examined the effects of short-term prednisone administration on the diurnal patterns of dehydroepiandrosterone (DHEA) and testosterone. Saliva samples were collected from 11 healthy, physically active, male volunteers for DHEA and testosterone analysis, as follows: every 4 h from 0800 to 2000 h on 2 control days without medication, and after 1 week of oral therapeutic prednisone treatment (60 mg daily) (days 0-3). Overall, a diurnal decline in the two steroid hormones was observed on the control days. After short-term glucocorticoid administration, DHEA concentrations were significantly decreased with a complete disappearance of the DHEA diurnal pattern, which lasted 2 days post-treatment. No glucocorticoid effect was observed for testosterone. The results indicate that short-term prednisone treatment affects the circadian pattern of saliva DHEA but not testosterone in healthy active volunteers. Further studies are necessary to determine whether this alteration in DHEA circadian pattern has clinical consequences in patients with chronic glucocorticoid therapy.

Abstract
Stress and adjustment to stress involve pathophysiological processes operating in the cardiovascular system, particularly concerning high blood pressure. Stress and high blood pressure are closely linked. Stress induces transient psychosomatic-related increases in blood pressure, but can also induce more permanent rise in blood pressure when associated with other environmental, psychological, or genetic risk factors. Symptomatic treatment of high blood pressure requires medicinal antihypertensive therapy; anti-stress therapy is an effective but not sufficient complement.

Abstract
To assess the eventual effects of acute oral salbutamol intake on performance and metabolism during submaximal exercise, nine healthy volunteers completed two cycling trials at a power corresponding to 80-85% VO2max, after either placebo (Pla) or salbutamol (Sal, 6 mg) treatment, according to a double-blind randomized protocol. Blood samples were collected both at rest and during exercise (5 min-, 10 min-, 15 min-exhaustion) for C-peptide, FFA, lactate and blood glucose measurements. Cycling performance was significantly improved in the Sal vs. Pla trials (p < 0.05). After Sal intake, resting C-peptide, lactate, FFA and blood glucose values were higher whereas exercise lactate and free fatty acid concentrations were greater during and at the conclusion of the exercise period (p < 0.05). These results suggest that acute salbutamol ingestion improved performance during submaximal exercise probably through an enhancement of the overall contribution to energy production from both aerobic and anaerobic metabolisms.
