Testosterone Effects on Short-Term Physical, Hormonal, and Neurodevelopmental Outcomes in Infants with 47,XXY/Klinefelter Syndrome: The TESTO Randomized Controlled Trial.

Context: 47,XXY/Klinefelter syndrome (XXY) is associated with impaired testicular function and differences in physical growth, metabolism, and neurodevelopment. Clinical features of XXY may be attributable to inadequate testosterone during the mini-puberty period of infancy.

Objective: We tested the hypothesis that exogenous testosterone treatment positively effects short-term physical, hormonal, and neurodevelopmental outcomes in infants with XXY.

Characteristics of Young Women Presenting With Acute Myocardial Infarction: The Prospective, Multicenter, Observational Young Women Presenting Acute Myocardial Infarction in France Study.

Background: The percentage of women <50 years of age hospitalized with myocardial infarction is increasing. We describe the clinical, morphological, and biological characteristics, as well as the clinical outcomes of this population.

Methods And Results: This prospective, observational study included consecutive women <50 years of age admitted for myocardial infarction at 30 centers in France (May 2017-June 2019).

[Tuberculosis aneurysm of descending thoracic aorta treated by covered stent graft : A case report].

Tuberculous aneurysm is a rare but lethal disease. It preferentially affects the aorta. The contamination occurs either secondarily to a tuberculosis site in contact with the aorta or by blood contamination.

Effect of phosphogypsum adding on setting kinetics and mechanical strength of geopolymers based on metakaolin or fly ash matrices.

Our study aims to highlight the effects of the addition of phosphogypsum on certain fresh and hardened characteristics of geopolymer matrices based on metakaolin or fly ash. In the fresh state, workability and setting were studied by rheology and by the electrical conductivity measurement. The hardened state was characterized by XRD, DTA, SEM, and compressive strength measurement.

[Intracardiac migration of the ureteral single-J : A case report and removal techniques].

The techniques of derivation of the high urinary tract are indispensable in common practice for the management of ureteral obstructions. Like any surgical gesture, its techniques are not without complications; Among those common are hematuria, urinary incontinence, migration in the bladder and rupture of the probe. However, intracardiac probe migration has rarely been described.
