HIIT produces increases in muscle power and free testosterone in male masters athletes

P Herbert, LD Hayes, NF Sculthorpe, and FM Grace

Introduction Peak muscle power is an important determinant of athletic performance across the lifespan that declines with age ( 1 ) and is accompanied by a precipitous decline in serum testosterone ( 2 ). Both present a noteworthy impediment

Kim Magaly Pabst, Robert Seifert, Nader Hirmas, Martina Broecker-Preuss, Manuel Weber, Wolfgang Peter Fendler, Timo Bartel, Sarah Theurer, Ken Herrmann, and Rainer Görges

Key points At a follow-up of >10 years, a single stimulated Tg measurement (maximum 24 months after last radioiodine therapy) seems to have a high predictive power for RFS. At a follow-up >10 years, a single highly sensitive measured

Cognitive performance during senescence in untreated congenital isolated GH deficiency

Individuals with untreated isolated GH deficiency (IGHD) due to a mutation in the GHRH receptor gene from Itabaianinha Brazil have increased insulin sensitivity, normal life expectancy, and an extended healthspan, i.e., the period of life free from disabilities. We hypothesize that their prolonged healthspan is accompanied by a delayed cognitive decline in senescence. To test this hypothesis, we have administered the Literacy Independent Cognitive Assessment (LICA) to 15 IGHD individuals aged over 50 years and 15 controls matched by age, sex, years of education, and percentage of illiteracy. All individuals were negative for HIV and syphilis serology, and there were no differences in serum levels of folate, vitamin B12 and TSH between the 2 groups, while free T4 was higher in the IGHD group. IGHD subjects had a higher total LICA score than controls, 215 (22.7) vs. 204.2 (18.1), without reaching statistical significance. Scores of memory, visuoconstruction, language and calculation were similar between the two groups, with better attention [9.5 (1.4) vs. 8.3 (1.1), p= 0.01], and executive function [38.3 (4.8) vs. 35.1 (2.5), p= 0.03] scores in IGHD. MANCOVA revealed that group (but no age) had a significant effect on the LICA variables (partial eta squared of 0.455, power of 0.812, p= 0.02). This effect is verified on attention (partial eta squared 0.216, power of 0.749, p= 0.01) and executive function (partial eta squared 0.154, power of 0.570, p= 0.03. In conclusion, IGHD in senescence is associated with similar total cognitive performance, but better attention and executive function than controls.

GATA transcription factors in testicular adrenal rest tumours

Manon Engels, Paul N Span, Rod T Mitchell, Joop J T M Heuvel, Monica A Marijnissen-van Zanten, Antonius E van Herwaarden, Christina A Hulsbergen-van de Kaa, Egbert Oosterwijk, Nike M Stikkelbroeck, Lee B Smith, Fred C G J Sweep, and Hedi L Claahsen-van der Grinten

Testicular adrenal rest tumours (TARTs) are benign adrenal-like testicular tumours that frequently occur in male patients with congenital adrenal hyperplasia. Recently, GATA transcription factors have been linked to the development of TARTs in mice. The aim of our study was to determine GATA expression in human TARTs and other steroidogenic tissues. We determined GATA expression in TARTs (n = 16), Leydig cell tumours (LCTs; n = 7), adrenal (foetal (n = 6) + adult (n = 10)) and testis (foetal (n = 13) + adult (n = 8)). We found testis-like GATA4, and adrenal-like GATA3 and GATA6 gene expressions by qPCR in human TARTs, indicating mixed testicular and adrenal characteristics of TARTs. Currently, no marker is available to discriminate TARTs from LCTs, leading to misdiagnosis and incorrect treatment. GATA3 and GATA6 mRNAs exhibited excellent discriminative power (area under the curve of 0.908 and 0.816, respectively), while immunohistochemistry did not. GATA genes contain several CREB-binding sites and incubation with 0.1 mM dibutyryl cAMP for 4 h stimulated GATA3, GATA4 and GATA6 expressions in a human foetal testis cell line (hs181.tes). Incubation of adrenocortical cells (H295RA) with ACTH, however, did not induce GATA expression in vitro. Although ACTH did not dysregulate GATA expression in the only human ACTH-sensitive in vitro model available, our results do suggest that aberrant expression of GATA transcription factors in human TARTs might be involved in TART formation.

Differential impact of osteoporosis, sarcopenia and obesity on physical performance in aging men

Franca Genest, Michael Schneider, Andreas Zehnder, Dominik Lieberoth-Leden, and Lothar Seefried


Aging and concurrent constitutional changes as sarcopenia, osteoporosis and obesity are associated with progressive functional decline. Coincidence and mutual interference of this risk factors require further evaluation.


Cross-sectional evaluation of musculoskeletal health in a community-dwelling cohort of men aged 65–90 years. Objectives included descriptive analysis of age-related decline in physical performance, prevalence of osteoporosis (FRAX-Score), sarcopenia (EWGSOP criteria) and obesity (BMI > 30 kg/m2) and their coincidence/interference.


Based on 507 participants assessed, aging was associated with progressive functional deterioration, regarding power (chair rise test −1.54% per year), performance (usual gait speed −1.38% per year) and muscle force (grip strength −1.52% per year) while muscle mass declined only marginally (skeletal muscle index −0.29% per year). Prevalence of osteoporosis was 41.8% (n = 212) while only 22.9% (n = 116) of the participants met the criteria for sarcopenia and 23.7% (n = 120) were obese. Osteosarcopenia was found in n = 79 (15.6%), sarcopenic obesity was present in 14 men (2.8%). A combination of all three conditions could be confirmed in n = 8 (1.6%). There was an inverse correlation of BMI with physical performance whereas osteoporosis and sarcopenia did not interfere with functional outcomes.


Based on current definitions, there is considerable overlap in the prevalence of osteoporosis and sarcopenia, while obesity appears to be a distinct problem. Functional decline appears to be associated with obesity rather than osteoporosis or sarcopenia. It remains to be determined to what extend obesity itself causes performance deficits or if obesity is merely an indicator of insufficient activity eventually predisposing to functional decline.
