- While left ventricular (LV) structure and function differ between hypertensive women and men, it remains unclear whether sex affects regression of LV hypertrophy with antihypertensive treatment. We analysed paired echocardiograms in 500 men and 347 women enrolled in the Losartan Intervention For Endpoint reduction in hypertension (LIFE) study at baseline and after 12 months of antihypertensive treatment with either losartan or atenolol. At enrollment, 177 women and 242 men were randomized to losartan-based treatment and 161 women and 247 men were randomized to atenolol-based treatment (sex difference=NS). After 12 months of antihypertensive treatment, blood pressure was lowered similarly in women (152/83 from 174/97 mmHg) and men (149/85 from 173/99 mmHg; both P<0.001, sex difference=NS), without significant change in body weight in either sex. Cardiac output and pulse pressure/stroke volume were equivalently reduced in both sexes (-0.2 vs -0.1 l/min and both -0.20 mmHg/ml/m(2), respectively; both P=NS). Absolute LV mass change after 12 months of antihypertensive treatment was greater in men than in women (-30 vs -24 g, P=0.01). However, after adjusting for baseline LV mass and randomized study treatment, LV mass reduction was greater in women than in men (-33 vs -23 g, P=0.001). LV mass regression was greater in women, by 8.0+/-2.8 g, after adjusting for baseline LV mass and randomized study treatment. After consideration of baseline LV mass and randomized study treatment, antihypertensive treatment regressed LV hypertrophy more in women. Further studies are needed to identify the mechanisms and prognostic implications of this sex-related difference.

- Abstract The co-authors of this paper hereby state their intention to work together to launch the Genomic Observatories Network (GOs Network) for which this document will serve as its Founding Charter. We define a Genomic Observatory as an ecosystem and/or site subject to long-term scientific research, including (but not limited to) the sustained study of genomic biodiversity from single-celled microbes to multicellular organisms.An international group of 64 scientists first published the call for a global network of Genomic Observatories in January 2012. The vision for such a network was expanded in a subsequent paper and developed over a series of meetings in Bremen (Germany), Shenzhen (China), Moorea (French Polynesia), Oxford (UK), Pacific Grove (California, USA), Washington (DC, USA), and London (UK). While this community-building process continues, here we express our mutual intent to establish the GOs Network formally, and to describe our shared vision for its future. The views expressed here are ours alone as individual scientists, and do not necessarily represent those of the institutions with which we are affiliated.
