Materials with strongly correlated electrons often exhibit interesting physical properties. An example of these materials is the layered oxide perovskite Sr 2 RuO 4 , which has been intensively investigated due to its unusual properties. Whilst the debate on the symmetry of the superconducting state in Sr 2 RuO 4 is still ongoing, a deeper understanding of the Sr 2 RuO 4 normal state appears crucial as this is the background in which electron pairing occurs. Here, by using low-energy muon spin spectroscopy we discover the existence of surface magnetism in Sr 2 RuO 4 in its normal state. We detect static weak dipolar fields yet manifesting at an onset temperature higher than 50 K. We ascribe this unconventional magnetism to orbital loop currents forming at the reconstructed Sr 2 RuO 4 surface. Our observations set a reference for the discovery of the same magnetic phase in other materials and unveil an electronic ordering mechanism that can influence electron pairing with broken time reversal symmetry. Strontium Ruthenate, Sr 2 RuO 4 , displays a remarkable number of intriguing physical phenomena, from superconductivity, to strain-induced ferromagnetism. Here, using low-energy muon spectroscopy, Fittipaldi et al. demonstrate the existence of unconventional magnetism at the surface of Sr 2 RuO 4 in its normal state and without any applied strain.

Purpose To assess the safety and efficacy of ultrasound coagulation of the ciliary body in refractory glaucoma. Methods This prospective multicenter interventional study was conducted in two Italian university-affiliated glaucoma centers: St. Orsola-Malpighi Teaching Hospital (Bologna, Italy) and University Eye Clinic of Genoa (Genoa, Italy). The main inclusion criterion was the diagnosis of glaucoma with a baseline intraocular pressure (IOP) ≥ 21 mmHg while on maximum topical and systemic medical hypotensive treatment. The EyeOP1 device (Eye Tech Care, Rillieux-la-Pape, France), which was employed in the study, uses miniaturized transducers to produce high-intensity focused ultrasound (HIFU). Treatment consisted of the sequential activation of each transducer lasting 4 s (group 1), 6 s (group 2) or 8 s (group 3). Hypotensive medications were interrupted after surgery and then prescribed only if postoperative IOP was ≥ 21 mmHg during follow-up visits. Patients were assessed before and 1, 7, 14, 30, 90 and 180 days after the procedure. Primary outcomes were the mean IOP reduction in the overall population and in groups 1, 2 and 3, and the rates of complete success, qualified success and failure. Results Thirty eyes (16 open-angle, 10 angle-closure and 4 neovascular glaucoma) of 30 patients were included. The mean preoperative IOP was 30.1 ± 10.5 mmHg. Twenty-nine patients completed the entire study follow-up; one patient exited from the study 3 months after HIFU and underwent trabeculectomy. At days 1 and 180, the mean IOP was significantly reduced (18.4 ± 7.2 and 20.2 ± 6.2 mmHg, respectively; all p  < 0.0001). Group 3 patients (8-s ultrasound exposure time) showed a greater IOP reduction than the other two groups (−16.2 ± 8.3 for group 3 vs. −8.8 ± 6.6 for group 2 and −3.7 ± 6.5 for group 1; p  = 0.02 and p  < 0.001, respectively). Qualified and complete success was achieved in 23.3 and 46.7% of patients, respectively; treatment failure was recorded in 6.6%. Conclusions Ultrasonic coagulation of the ciliary body is a safe and effective procedure for reducing IOP in refractory glaucoma. The increase in ultrasound exposure time appears to improve the response rate and the global efficacy of the procedure, with no detrimental effect on safety.

IntroductionFunctional Movement Disorders (FMD) are characterized by the presence of neurological symptoms that cannot be explained by typical neurological diseases or other medical conditions. First evidence showed that, compared to healthy controls (CTR), FMD patients presented increased levels of glutamate+glutamine in the anterior cingulate cortex/medial prefrontal cortex, and decreased levels of glutamate in the cerebrospinal fluid, suggesting that a glutamatergic dysfunction might play a role in FMD pathophysiology.ObjectivesAccording to the evidence of these abnormalities in many neuropsychiatric disorders at level of brain network activity, connectivity, and specific anatomic areas of altered metabolic, and given the evidence of a potential role of glutamate and BDNF in the pathophysiology of FND, in this study we aimed to assess circulating levels of glutamate, BDNF, dopamine, oxidative stress biomarkers, creatinine, neopterin and uric acid in patients with FMD and in a control group of healthy subjects.Methods12 FMD patients (4 males, 8 females) and 20 CTR (4 males, 16 females) were recruited and underwent venous blood sampling and urine collection: levels of glutamate, BDNF, dopamine, oxidative stress, creatine, neopterin, and uric acid were analysed. Participants also underwent a psychometric assessment investigating depression, anxiety, and alexithymia.ResultsLevels of glutamate, BDNF and dopamine were significantly lower in the blood of FMD patients than CTR. Glutamate and dopamine levels were positively associated with levels of alexithymia.ConclusionsOur findings give further evidence that glutamatergic dysfunction might be involved in the pathophysiology of FMD, possibly representing a biomarker of disease; moreover, since glutamatergic and dopaminergic system are closely interconnected, our results might have a relevance in terms of treatment options for FMD patients.Disclosure of InterestNone Declared

Objectives. This study sought to verify the independent role of heart rate in the prediction of all-cause, cardiovascular, and noncardiovascular mortality in a low-risk male population. Methods. In an Italian population-based observational study, heart rate was measured in 2533 men, aged 40 to 69 years, between 1984 and 1993. Data on cardiovascular risk factors were collected according to standardized procedures. Vital status was updated to December 1997. Results. Of 2533 men followed up (representing 24 457 person-years), 393 men died. Age-adjusted death rates for 5 heart rate levels showed increasing trends. The adjusted hazard rate ratios for each heart rate increment were 1.52 (95% confidence interval [CI] = 1.29, 1.78) for all-cause mortality, 1.63 (95% CI = 1.26, 2.10) for cardiovascular mortality, and 1.47 (95% CI = 1.19, 1.80) for noncardiovascular mortality. Relative risks between extreme levels were more than 2-fold for all endpoints considered. Conclusions. Heart rate is an independent predictor of cardiovascular, noncardiovascular, and total mortality in this Italian middle-aged male population.

Background In monitoring population health and the effectiveness of public health strategies, the body mass index (BMI) is often assessed within national surveys from self-reported height and weight rather than measured values. Using data collected within a recent health examination survey (HES), the discrepancies between self-reported and measured values were assessed, and correction models were estimated and implemented on national interview survey data. Methods Within the CUORE Project, the Italian National Institute of Health conducted the HES 2018-2019 measuring height and weight as well as collecting data on self-reported values in random samples of general population aged 35-74 years residing in ten (of 20) Italian regions distributed in the North, Centre and South: 1033 men and 1061 women. Results Self-reported and measured data comparison showed greater differences in mean values of height than weight and in women than in men (height +2 cm in men and +3.2 in women; weight -0.7 kg and -1.4 kg, respectively) and a corresponding underestimation of BMI (-0.7 kg/m2 and -1.4 kg/m2, respectively). Differences were stable across age groups and educational levels, except for height discrepancy, which was greatest in women aged 65-74 years. Self-reported vs measured prevalence were: normal weight 39.7%-33.3% in men and 54.8%-44.7% in women, overweight 45.8%-46.1% and 26.0%-29.2%, obesity 13.8%-20.1% and 15.7%-23.9%. Linear regression models adjusted by sex and age classes were assessed for height and weight (R2 > =0.92) and implemented to estimate adjusted BMI and normal weight/overweight/obesity prevalence on the national multi-purpose interview survey data collected by the Italian National Institute of Statistics. Conclusions To provide more accurate prevalence of normal weight, overweight and obesity, self-reported values could be adjusted using correction models developed on the basis of the relationship between self-reported and measured height and weight values. Key messages • Discrepancies between self-reported and measured values of height and weoght were found. • Self-reported values could be adjusted using correction models developed on the basis of the relationship between self-reported and measured height and weight values.

Background Italian National Prevention Plan 2005-08 included 10-year cardiovascular risk assessment (10-CR) for the general population aged 35-69 years using the CUORE Project risk score. GPs were encouraged to perform 10-CR and send data to the Cardiovascular Risk Observatory (CRO). Aim To show updated data of the ongoing surveillance system of the 10-CR in the Italian adult population. Methods Data were collected using the cuore.exe software, freely downloadable by GPs from the CUORE Project website (www.cuore.iss.it). The CRO provides a web-platform to compare data on 10-CR and risk factors at regional/national level. For persons examined at least twice, variations in risk factors from baseline to follow-up and 95% confidence intervals (C.I.) were calculated using methods for matched pair samples. Results Up to February 2019, about 3,500 GPs downloaded cuore.exe; about 300,000 CR assessments on about 140,000 persons were sent to CRO. Mean CR was 3.1% in women (W), 8.5% in men (M); 28% of M, 64% of W were at low risk (CR < 3%); 9.9% of M, 0.4% of W were at high risk (CR ≥ 20%); 26% of M, 16% of W were current smokers; 13% of M, 10% of W were diabetic; 33% of hypertensive M, 35% of hypertensive W were under specific treatment. Among those with at least two risk assessments (31% of the sample), 11% shifted to a lower risk class after one year (14% of M, 7% of W). Systolic blood pressure mean levels decreased by 0.6 mmHg (95%-C.I. 0.3-0.8 mmHg), diastolic blood pressure by 0.5 mmHg (0.2-0.7 mmHg), total cholesterol by 4.1 mg/dl (3.0-5.2 mg/dl), smokers prevalence by 3.1% (2.3%-4.0%); HDL-cholesterol increased in W by 0.3 mg/dl (0.1-0.5 mg/dl). Conclusions Data demonstrate that 10-CR assessment can be an effective first step to implement preventive actions in primary care. Individual risk score is a useful tool for GPs to assess CR and promote primary prevention focusing on the adoption of healthy lifestyles. Data can be used to support health policy decision process. Key messages The cuore.exe software, freely downloadable from the CUORE Project website-www.cuore.iss.it, allows GPs to assess the CUORE Project risk score, to collect and to send data to the CVD Risk Observatory. 10 year Cardiovascular Risk assessment in the general adult population can be an effective first step to implement preventive actions in primary care.

Background The WHO Global Action Plan for the Prevention of NCDs recommends a 30% relative reduction in mean population intake of salt/sodium. To this end, the Italian Ministry of Health (MoH) has strengthened prevention and health promotion through the “Gaining health: making healthy choices easy” Programme and the National Preventive Plan 2014-2019, in collaboration with the Interdisciplinary Working group for Salt Reduction in Italy. To estimate the habitual salt intake and its trend in the general adult population, national surveys, funded by the MoH-CCM, are conducted within the CUORE Project. Methods Baseline salt intake by the use of 24h urine collections was assessed in 2008-2012 from representative random samples of residents in all Italian Regions. A new survey was conducted in 2018-2019 involving random samples of residents in 10 Regions. Urinary sodium excretion is assayed by a central lab at Federico II University of Naples, subjected to strict quality controls. Comparisons are made considering, for both periods, the first seven regions examined in the 2018-2019 survey and the age range of 35-74 years. Results Within the 2008-2012 survey, mean level of sodium chloride per day in 642 men and 627 women were 10.6 g (10.3-11.0 g) and 8.0 g (7.7-8.3 g) respectively, whereas in the 2018-2019 survey the corresponding mean levels in 673 men and 709 women were 9.3 g (95% C.I.: 9.1-9.6 g) and 7.1 g (6.9-7.3 g), respectively. A sodium chloride intake level lower than the WHO recommended target of 5g/day (or 85 mmol/day) was detected in 5% (3-6%) of men and 16% (13-19%) of women examined in 2008-2012 vs 9% (6-11%) of men and 24% (20-27%) of women examined in 2018-2019. Conclusions These preliminary data show that the average habitual sodium intake in Italy is still higher than recommended but a significant reduction seems to occur. These results fully justify and encourage the ongoing preventive initiatives of MoH, facilitating the meeting of the WHO-NCD target. Key messages Habitual salt intake in the Italian general adult population is still higher than the recommended by the WHO. If confirmed, in the last ten years a reduction of habitual salt intake in Italian general adult population seems to be occurred.

Background The WHO Global Action Plan for the Prevention of Non-Communicable Disease (WHO-NCD) recommends a 25% relative reduction in the prevalence of raised blood pressure (RBP) by 2025. Prevalence of RBP and mean blood pressure in the Italian general adult population measured in the 2018 CUORE Project-Health Examination Survey are presented to investigate if Italy can reach this target. Methods Within the health examination survey conducted in 2018-2019, representative random samples of resident population, aged 35-74 years, stratified by age and sex (822 men and 869 women) were examined in 8 Italian Regions from the Northern, Central and Southern Italy. Blood pressure was measured by automated oscillometric device using standardized procedures and methods; mean level of two measurements are here considered. RBP is defined as systolic and/or diastolic blood pressure equal or greater than 140/90 mmHg or being under specific drug treatment. The survey is funded by the Italian Ministry of Health-CCM. Results Preliminary analysis shows that prevalence of RBP is 43% (95% C.I. 40-47) in men and 32% (29-36) in women. Prevalence of persons with raised blood pressure and not receiving pharmacological treatment is 19% (15-22) in men and 9% (5-12) in women. In men and women prevalence of raised blood pressure is significantly higher in the Southern Regions. Mean value of systolic blood pressure is 131 mmHg (130-132) in men and 122 mmHg (121-123) in women. Mean value of diastolic blood pressure is 77 mmHg (76-78) in men and 73 mmHg (72-74) in women. Conclusions Preliminary data underline that RBP is commonly observed in the Italian adult population. However, in comparison to data measured within the CUORE Project 10 years earlier, prevalence of RBP and mean blood pressure are declining, facilitating the meeting of WHO-NCDs target. Key messages Raised blood pressure is commonly observed in the Italian general adult population. If confirmed, in the last ten years prevalence of raised blood pressure and mean blood pressure are declining in the Italian general adult population.

Background The WHO Global Action Plan for the Prevention of Non-Communicable Disease (WHO-NCD) recommends to halt the rise of obesity by 2025. Obesity is largely preventable. This preliminary analysis aims to assess mean level of BMI and prevalence of obesity in the Italian general adult population using the data collected within the CUORE Project to investigate if Italy can meet the WHO-NCD target. Methods Within the health examination survey conducted in 2018-2019, mean level of BMI and prevalence of obesity (BMI > =30 kg/m2) and overweight (25 < =BMI<30 kg/m2) were assessed in representative random samples of resident population, aged 35-74 years, stratified by age and sex (822 men and 869 women), from 8 Italian Regions in Northern, Central and Southern Italy. Weight and height were measured using standardized methods. A standardized questionnaire was used to collect data on educational level that was used as a proxy of socio-economic status. The survey is funded by the Italian Ministry of Health-CCM. Results In this preliminary analysis, mean level of BMI was 26.8 kg/m2 (95% C.I. 26.5-27.1) in men and 25.9 kg/m2 (25.6-26.3) in women. Prevalence of obesity was 19% (16-22) in men and 22% (19-25) in women; prevalence of overweight was 45% (41-48) in men and 28% (25-31) in women. Obesity resulted significantly higher in persons with lower educational level (primary or middle school) vs those with higher education: 26% (20-31) vs 16% (13-19) in men and 33% (27-38) vs 17% (14-20) in women. Both in men and women prevalence of obesity was significantly higher in the Southern regions. Conclusions Preliminary data show that more than half of Italian adults are overweight/obese. However, in comparison to BMI measured in the CUORE Project 10 years earlier, the prevalence of people at normal weight is increasing, moving in the direction of the WHO-NCDs obesity target. Preventive actions at community level should be more incisive in the population at low socio-economic level. Key messages Mean BMI and prevalence of obesity in the Italian general adult population are still high. If confirmed, in the last ten years an increase of normal weight prevalence in the Italian general adult population seems to be occurred.

Background: Hepatitis C virus (HCV) infection is common worldwide but there are different prevalence rates in different countries. Data on the incidence of HCV in the general population are scarce. Spontaneous viral clearance occurs in 10–25% of infected individuals after acute infection yet controversy exists regarding the frequency of spontaneous clearance during the natural course of HCV infection in the general population. Aims: Anti-HCV prevalence, HCV infection rate, and the kinetics of anti-HCV were studied in a cross section of the general population of central Italy. Study population and methods: Anti-HCV prevalence (EIA-3 Ortho, RIBA-3 Ortho Chiron) was estimated in 3884 randomly selected individuals. Infection rate and antibody kinetics were estimated in 2032 participants for whom a second blood sample was taken after a median follow up of seven years. HCV-RNA determination by polymerase chain reaction was performed on follow up sera. Results: The overall confirmed anti-HCV prevalence was 2.4%. Two participants seroconverted for anti-HCV, giving an overall infection rate of 1.4 cases per 10 000 person years (95% confidence interval 0.2–5.2 per 10 000 person years). Of the 36 individuals confirmed as anti-HCV positive at enrolment, seven (19.4%) showed complete seroreversion. Seven (87%) of the eight individuals with indeterminate results at enrolment were serologically non-reactive at the end of follow up. Of the 25 participants confirmed to be anti-HCV positive at both enrolment and follow up, 23 (92.0%) with stable serological profiles tested positive for HCV-RNA at the end of follow up. Conclusions: There is still a permanent risk, although low, of HCV spread in the general population in an area of low level endemicity. In this setting, a wide spectrum of modifications of viral and antibody patterns can be observed in HCV infected patients.
