Article Synopsis
- - Obesity may lead to shorter telomeres due to increased oxidative stress and inflammation, impacting individuals throughout their lives.
- - A meta-analysis of 87 studies involving over 146,000 people revealed that each unit increase in BMI correlates with a significant decrease in telomere length, particularly among young adults.
- - The findings highlighted a stronger association of BMI with telomere length in the white population, with no notable differences observed between sexes.
No controlled studies exist regarding the pharmaceutical reduction of ataxia symptoms in ataxia telangiectasia (A-T). In a multicenter, double-blind, randomized, placebo-controlled crossover trial, oral betamethasone (BETA) and placebo were compared in terms of their reduction of ataxia symptoms as assessed with the International Cooperative Ataxia Rating Scale (ICARS). In this study of 13 A-T children, betamethasone reduced the ICARS total score by a median of 13 points in the intent-to-treat population and 16 points in the per-protocol population (ie, median percent decreases of ataxia symptoms of 28% and 31%, respectively).

Corpus callosum abnormalities are common brain malformations with a wide clinical spectrum ranging from severe intellectual disability to normal cognitive function. The etiology is expected to be genetic in as much as 30-50% of the cases, but the underlying genetic cause remains unknown in the majority of cases.

Urinary EMA concentrations detected by (1)H-NMR spectroscopy were studied in 130 subjects with CNS impairment of unknown origin (with no definite diagnosis, no specific symptoms or signs, and normal common biochemical and metabolic screening results) and 130 age- and sex-matched healthy subjects. EMA levels exceeding two standard deviations (SD) above normal (i.
