The criteria for the diagnosis of the polycystic ovary syndrome (PCOS) have still not been agreed universally. A population of 1741 women with PCOS were studied, all of whom had polycystic ovaries seen by ultrasound scan. The frequency distributions of the serum concentrations of follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone and prolactin and the body mass index, ovarian volume, uterine cross-sectional area and endometrial thickness were determined and compared with the symptoms and signs of PCOS. Obesity was associated with hirsutism and an elevated serum testosterone concentration and was also correlated with increased rates of infertility and cycle disturbance. The rates of infertility and cycle disturbance also increased with serum LH concentrations > 10 IU/l. A rising serum concentration of testosterone [mean and 95th percentiles 2.6 (1.1-4.8) nmol/l] was associated with an increased risk of hirsutism, infertility and cycle disturbance. The ovarian volume was correlated with serum concentrations of testosterone, LH and the body mass index, which was also correlated with the uterine area. This descriptive data from the largest reported series of women with PCOS enables the development of a management-orientated approach to the syndrome. Women who are overweight can expect an improvement in their symptoms if they lose weight. An elevated concentration of LH (> 10 IU/l) is associated with infertility and treatment should be chosen accordingly. If the serum testosterone concentration is > 4.8 nmol/l, other causes of hyperandrogenism should be excluded.

This study demonstrates that pretreatment with a potent and selective LTD4 antagonist markedly attenuates exercise-induced bronchoconstriction, and it suggests that LTD4 is a major mediator of this type of bronchoconstriction.

The objective of Integrated Care Pathways for Airway Diseases (AIRWAYS-ICPs) is to launch a collaboration to develop multi-sectoral care pathways for chronic respiratory diseases in European countries and regions. AIRWAYS-ICPs has strategic relevance to the European Union Health Strategy and will add value to existing public health knowledge by: 1) proposing a common framework of care pathways for chronic respiratory diseases, which will facilitate comparability and trans-national initiatives; 2) informing cost-effective policy development, strengthening in particular those on smoking and environmental exposure; 3) aiding risk stratification in chronic disease patients, using a common strategy; 4) having a significant impact on the health of citizens in the short term (reduction of morbidity, improvement of education in children and of work in adults) and in the long-term (healthy ageing); 5) proposing a common simulation tool to assist physicians; and 6) ultimately reducing the healthcare burden (emergency visits, avoidable hospitalisations, disability and costs) while improving quality of life. In the longer term, the incidence of disease may be reduced by innovative prevention strategies. AIRWAYSICPs was initiated by Area 5 of the Action Plan B3 of the European Innovation Partnership on Active and Healthy Ageing. All stakeholders are involved (health and social care, patients, and policy makers). @ERSpublications AIRWAYS-ICPs: launch of a collaboration to develop multi-sectoral integrated care pathways for respiratory disease http://ow.ly/v35Gh PERSPECTIVE INTEGRATED CARE PATHWAYS FOR AIRWAY DISEASES

Dosing exercise as brief, intense 'exercise snacks' before main meals is a time-efficient and effective approach to improve glycaemic control in individuals with insulin resistance.
