First narrow-band search for continuous gravitational waves from known pulsars in advanced detector data
Spinning neutron stars asymmetric with respect to their rotation axis are potential sources of
continuous gravitational waves for ground-based interferometric detectors. In the case of known pulsars a
fully coherent search, based on matched filtering, which uses the position and rotational parameters
obtained from electromagnetic observations, can be carried out. Matched filtering maximizes the signalto-
noise (SNR) ratio, but a large sensitivity loss is expected in case of even a very small mismatch
between the assumed and the true signal parameters. For this reason, narrow-band analysis methods have
been developed, allowing a fully coherent search for gravitational waves from known pulsars over a
fraction of a hertz and several spin-down values. In this paper we describe a narrow-band search of
11 pulsars using data from Advanced LIGO’s first observing run. Although we have found several initial
outliers, further studies show no significant evidence for the presence of a gravitational wave signal.
Finally, we have placed upper limits on the signal strain amplitude lower than the spin-down limit for 5 of
the 11 targets over the bands searched; in the case of J1813-1749 the spin-down limit has been beaten for
the first time. For an additional 3 targets, the median upper limit across the search bands is below the
spin-down limit. This is the most sensitive narrow-band search for continuous gravitational waves carried
out so far

Primary prevention efforts are poorly developed in people at high cardiovascular risk: A report from the European Society of Cardiology EURObservational Research Programme EUROASPIRE V survey in 16 European countries
Background: European Action on Secondary and Primary Prevention by Intervention to Reduce Events (EUROASPIRE)
V in primary care was carried out by the European Society of Cardiology EURObservational Research Programme in
2016–2018. The main objective was to determine whether the 2016 Joint European Societies’ guidelines on cardiovascular disease prevention in people at high cardiovascular risk have been implemented in clinical practice.
Methods: The method used was a cross-sectional survey in 78 centres from 16 European countries. Patients without a
history of atherosclerotic cardiovascular disease either started on blood pressure and/or lipid and/or glucose lowering
treatments were identified and interviewed 6 months after the start of medication.
Results: A total of 3562 medical records were reviewed and 2759 patients (57.6% women; mean age 59.0 11.6 years)
interviewed (interview rate 70.0%). The risk factor control was poor with 18.1% of patients being smokers, 43.5%
obese (body mass index 30 kg/m2
) and 63.8% centrally obese (waist circumference 88 cm for women, 102 cm for
men). Of patients on blood pressure lowering medication 47.0% reached the target of <140/90 mm Hg (<140/85 mm Hg
in people with diabetes). Among treated dyslipidaemic patients only 46.9% attained low density lipoprotein-cholesterol
target of <2.6 mmol/l. Among people treated for type 2 diabetes mellitus, 65.2% achieved the HbA1c target of <7.0%.
Conclusion: The primary care arm of the EUROASPIRE V survey revealed that large proportions of people at high
cardiovascular disease risk have unhealthy lifestyles and inadequate control of blood pressure, lipids and diabetes. Thus,
the potential to reduce the risk of future cardiovascular disease throughout Europe by improved preventive cardiology
programmes is substantial
