- Breath tests cover the fraction of nitric oxide in expired gas (FeNO), volatile organic compounds (VOCs), variables in exhaled breath condensate (EBC) and other measurements. For EBC and for FeNO, official recommendations for standardised procedures are more than 10 years old and there is none for exhaled VOCs and particles. The aim of this document is to provide technical standards and recommendations for sample collection and analytic approaches and to highlight future research priorities in the field. For EBC and FeNO, new developments and advances in technology have been evaluated in the current document. This report is not intended to provide clinical guidance on disease diagnosis and management. Clinicians and researchers with expertise in exhaled biomarkers were invited to participate. Published studies regarding methodology of breath tests were selected, discussed and evaluated in a consensus-based manner by the Task Force members. Recommendations for standardisation of sampling, analysing and reporting of data and suggestions for research to cover gaps in the evidence have been created and summarised. Application of breath biomarker measurement in a standardised manner will provide comparable results, thereby facilitating the potential use of these biomarkers in clinical practice.

- Background. Asymptomatic atherosclerosis is a common entity even at young age. Studies have suggested a strong relationship between increased arterial stiffness and asymptomatic carotid atherosclerosis (ACA) in general population, particularly in those with high cardiovascular risk, but no data exist from a younger population free from recognized cardiovascular disease. Hypothesis. We hypothesized there is an association between ACA and aortic pulse wave velocity (PWVao) in middle-aged, apparently healthy, normotensive population to reveal increased cardiovascular risk. Methods. We examined the relationship between ACA and PWVao in 236 apparently healthy, asymptomatic, normotensive, middle-aged subjects (age 47 ± 8 years; 52% women). PWVao was measured with the oscillometric method (Arteriograph). ACA was assessed by carotid artery ultrasonography. Results. ACA was present in 51 subjects. Subjects with ACA were older (p<0.009), more likely to be smokers (p<0.001), and had higher systolic blood pressure (SBP, 128 ± 9 vs. 125 ± 10 mmHg, p=0.048) and PWVao (9.3 ± 1.6 vs. 7.9 ± 1.3 m/s, p<0.001) than subjects without ACA. In a stepwise logistic regression analysis, only PWVao (odds ratio: 1.88, p<0.001), smoking habit (odds ratio 3.79, p=0.003), systolic blood pressure (odds ratio 1.05, p=0.046), and diastolic blood pressure (odds ratio: 0.94, p=0.038) were independently associated with ACA. PWVao >8.3 m/s identified ACA with a 71% sensitivity, 65% specificity, 36% positive and 89% negative predictive value, 2.04 relative risk, and 4.54 odds ratio, respectively. Conclusions. PWVao measured by the Arteriograph proved to be an independent marker of ACA. Our study may reveal high CV risk, detected as increased PWVao, which according to our study is related in a very high probability to asymptomatic carotid atherosclerosis in apparently healthy, young, and middle-aged subjects.

- Periodic limb movements during sleep and obstructive sleep apnea are both associated with increased sympathetic tone, and have been proposed as risk factors for heart diseases and, in particular, cardiovascular disease. As sympathetic system activation may lead to dyslipidaemia, periodic limb movements during sleep could be an additional risk factor for cardiovascular disease in patients with obstructive sleep apnea. The aim of the study was to determine whether the presence of periodic limb movements during sleep affects serum lipid levels in obstructive sleep apnea. Total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, non- high-density lipoprotein cholesterol and triglyceride levels were investigated in 4138 patients with obstructive sleep apnea in the European Sleep Apnea Database (ESADA) cohort, divided into those with periodic limb movements during sleep index & GE; 15 per hr (n = 628) and controls (n = 3510). ANCOVA adjusted for age, sex, body mass index, apnea-hypopnea index, alcohol intake, smoking status, diabetes, insomnia and study site was used to assess differences in lipids between periodic limb movements during sleep and controls. Patients with periodic limb movements during sleep (24% female, 54.4 & PLUSMN; 12.1 years, body mass index 31.9 & PLUSMN; 5.8 kg m(-2), apnea-hypopnea index 36.7 & PLUSMN; 25.4 per hr) had higher triglyceride (1.81 & PLUSMN; 1.04 versus 1.69 & PLUSMN; 0.90 mmol L-1, p = 0.002) and lower high-density lipoprotein cholesterol (1.19 & PLUSMN; 0.34 versus 1.24 & PLUSMN; 0.37 mmol L-1, p = 0.002) levels, whilst there was no difference in either total cholesterol (4.98 & PLUSMN; 1.10 versus 4.94 & PLUSMN; 1.07 mmol L-1), low-density lipoprotein cholesterol (3.04 & PLUSMN; 0.96 versus 2.98 & PLUSMN; 0.98 mmol L-1) or non- high-density lipoprotein cholesterol (3.78 & PLUSMN; 1.10 versus 3.70 & PLUSMN; 1.05 mmol L-1) concentrations (all p > 0.05). The results remained unchanged after most sensitivity analyses. Patients with obstructive sleep apnea with periodic limb movements during sleep had more prevalent cardiovascular disease (11% versus 6%, p < 0.01). Periodic limb movements during sleep in obstructive sleep apnea is associated with dyslipidaemia independently of important confounders. Our results highlight periodic limb movements during sleep as an additional risk factor for cardiovascular disease in obstructive sleep apnea.
