A case of intestinal anisakiasis caused by Anisakis sp. larva type I in a woman from Italy who consumed raw marinated anchovies, is reported. The diagnosis was based on the morphological features characteristic of anisakid larval stages, which were readily recognized in a large granuloma removed after emergency surgical treatment.
The aneutronic 11B(p, α)2α fusion reaction driven by the interaction of high-energy lasers with matter has become a popular topic of research, since it represents a potential long-term goal alternative to the most studied deuterium-tritium reaction. However, the detection of the typical ionic products, especially alpha particles, of this low-rate fusion reaction is a challenging issue, due to their low flux. One of the diagnostic devices that can be implemented in laser-driven proton-boron fusion experiments is a Thomson spectrometer (TS), which is capable of detecting and discriminating ions according to their mass-to-charge ratio (A/Z, where A is the mass number and Z is the atomic number of the ions). In this work, we report on the ultimate test of a TS, which was designed and developed at the ENEA Research Centre in Frascati, Italy, in the context of a p + 11B fusion experiment. Our device—designed to have high sensitivity and a robust shielding against electromagnetic pulses (EMPs)—was implemented at the PALS laser facility (∼700 J in ∼350 ps pulses) at a distance of 367 mm from the laser-plasma interaction point. We analyse here the measured signals obtained with our device, focusing on the assessment of their signal-to-background ratio. Despite the presence of strong EMPs and background radiation at such a short distance from the laser-irradiated target, the TS proved to be suitable for effectively detecting protons and heavier ions stemming from the plasma source.
The time-of-flight technique coupled with semiconductor detectors is a powerful instrument to provide real-time characterization of ions accelerated because of laser–matter interactions. Nevertheless, the presence of strong electromagnetic pulses (EMPs) generated during the interactions can severely hinder its employment. For this reason, the diagnostic system must be designed to have high EMP shielding. Here we present a new advanced prototype of detector, developed at ENEA-Centro Ricerche Frascati (Italy), with a large-area (15 mm × 15 mm) polycrystalline diamond sensor having 150 μm thickness. The tailored detector design and testing ensure high sensitivity and, thanks to the fast temporal response, high-energy resolution of the reconstructed ion spectrum. The detector was offline calibrated and then successfully tested during an experimental campaign carried out at the PHELIX laser facility (

100 J,
${\tau}_L = 750$
fs,
${I}_L\sim \left(1{-}2.5\right)\times {10}^{19}$
W/cm2) at GSI (Germany). The high rejection to EMP fields was demonstrated and suitable calibrated spectra of the accelerated protons were obtained.
Porous materials have many applications for laser–matter interaction experiments related to inertial confinement fusion. Obtaining new knowledge about the properties of the laser-produced plasma of porous media is a challenging task. In this work, we report, for the first time to the best of our knowledge, the time-dependent measurement of the reflected light of a terawatt laser pulse from the laser-produced plasma of low-Z foam material of overcritical density. The experiments have been performed with the ABC laser, with targets constituted by foam of overcritical density and by solid media of the same chemical composition. We implemented in the MULTI-FM code a model for the light reflection to reproduce and interpret the experimental results. Using the simulations together with the experimental results, we indicate a criterion for estimating the homogenization time of the laser-produced plasma, whose measurement is challenging with direct diagnostic techniques and still not achieved.
The aim of this pilot study is to assess, in a sample of patients with chemical (alcohol) and behavioural (gambling) dependence, the specifical association between core symptoms and Separation Anxiety Disorder, both in Childhood and in Adulthood.
Materials and methods
After a stabilization period of three months, outpatients with alcohol dependence (n = 30), patological gambling (n = 30) and a control group of anxiety disorders (n = 30) will be assessed with the following psychometric battery:
• SCI-SAS (Structured Clinical Interview for Separation Anxiety) Child and Adult
• SASI (Separation Anxiety Symptom Inventory)
• ASA-27 (Adult Separation Anxiety Questionnaire)
• TCI-R (Temperament anc Character Inventory Revised)
• GAF (Global Assess of Functioning)
• SCL-90-R (Symptom Checklist Revised)
• SOGS (South Oaks Gambling Scale)
• ADS (Alcohol Dependence Scale)
• HAM-A (Hamilton Anxiety Rating Scale)
Results
A preliminary analisys of collected datas (n = 33) shows a strong inter-reliability of the Separation Anxiety Scales (SCI-SAS, SASI and ASA-27) with a p = 0.001 and an association between levels of functioning (GAF) and ASA-27 and SASI scores (p = 0.010 and p = 0,001).
It shows a statistical correlation between ASA-27 and TCI-R: inverse proportion with Self Directness (SD) (p = 0.004) and direct relation with Self Trascendency (ST) (p = 0.003).
Conclusions
Even if the sample is still limited we found an interesting trend between Separation Anxiety symptoms, TCI-R dimensions and core symptoms of dependance. We should focus better, when the study will be over, on narrow and specific sub-analisys that should lead us to a better understanding of the disorders.
Adult Separation Anxiety Disorder (ASAD) is related to greater personal dysfunction and to a reduced sensitivity to conventional treatment, such as cognitive-behavioural therapy or anti-panic drugs, even considering severity of anxiety symptoms, number of co-morbid disorders, socioeconomical status, disease duration, and severity of agoraphobia.
Objectives:
To evaluate separation anxiety, psychiatric co-morbidity, levels of anxiety, character and temperament personality traits, and global functioning, in subjects with anxiety disorders attending a tertiary-level outpatient clinic.
Aims:
To predict the outcome and customize treatment for anxiety disorders.
Methods:
After symptom stabilization of one month (T0) 40 patients with anxiety disorders were assessed by means of SCI- SAS, SASI, ASA -27, MINI, HAM- A, TCI-R, GAF. Prospective evaluation is planned at T60 and T180.
Results:
According to preliminary cross-sectional data, higher scores of separation anxiety show statistically significant correlations with some domains of the TCI-R; in addition, patients with ASAD show greater psychiatric co-morbidity. No correlations were found between the presence of separation anxiety and levels of anxiety at HAM-A or GAF scores at baseline.
Conclusions:
The prospective study of long-term response to treatment is ongoing and the sample will be expanded. The comprehension of anxiety symptoms appraisal in the framework of psychobiological personality characteristics is expected to influence the choice of both pharmacological and psychological therapeutic tools, particularly in patients showing higher levels of dysfunction.
Pathological Gambling (PG) includes extremely different types of game and many gamblers suffer from anxiety disorders. According to the self-medication hypothesis, Gambling Behaviour may be a strategy to tolerate suffering and compensate uneasiness; otherwise social problems related to gambling may lead to anxiety disorders, possibly unmasking an adult form of Separation Anxiety Disorder (SAD).
Aims:
To investigate possible relationships between PG and SAD, considering the different games, the age of onset, the symptom severity, and the distinction between Adult and Child SAD.
Methods:
32 gamblers attending an outpatient psychiatric clinic completed the following tests: SOGS and ASI to investigate the kind of gambling, the age of onset and the social conditions of gamblers; SCI-SAS, SASI, ASA-27 to evaluate the Separation Anxiety in childhood and adulthood; HAM-A; GAF.
Results:
There are statistically significant correlations between later age of onset of PG and development of SAD in adults. Higher scores in GAF are related to lower scores in Separation Anxiety scales and HAM-A. There is a strong inter-correlation among the Separation Anxiety scales. Higher scores in HAM-A correlate with higher scores in SASI and ASA-27. Male gamblers have an earlier onset and increasing with the age of onset increases the addiction to “dissociative” games instead of “active” ones.
Conclusions:
Our preliminary data do not support self-medication hypothesis; possibly, a later-onset gambling is related to a more neurotic and less impulsive psychopathological pattern.
Stigma towards mental illness and psychiatry have a major impact on psychiatric patients’ quality of life; in particular, prejudicial beliefs make it more difficult for future doctors to send patients to mental health services, leading to a delay of necessary care.
Aims
Our aim is to evaluate the stigma towards mental illness and psychiatry, in a sample of Italian medical students. We studied the differences between the first-year students who have not attended the academic course in psychiatry, compared to the senior students who have attended the psychiatric lectures.
Methods
We tested 113 medical students, using the following questionnaires:
– Attitudes Towards Psychiatry (ATP 30);
– Community Attitudes Towards Mental Ill (CAMI);
– Perceived Discrimination Devaluation Scale (PDD), to assess the discrimination towards mental illness perceived in society;
– Baron-Cohen's Empathy Quotient (EQ), to measure empathy.
Results
Among the 113 students, 46 have already attended the academic course of psychiatry and CAMI scores were less stigmatizing as total score (P = 0.014) and in authoritarianism subscale (P = 0.049), social restriction (P = 0.022) and ideology of mental health in the community (P = 0.017). However, there were no statistically significant differences in empathy, perceived discrimination in the society and stigmatization of psychiatry.
Conclusions
The 67 students who have not attended the academic course of psychiatry are more stigmatizing, considering psychiatric patients as inferior people that require coercive attitudes, socially dangerous and that should be treated faraway from the community. Studying psychiatry is therefore useful to reduce, in the future doctors, these prejudices toward mentally ill patients.

Illicit drug use is well known as an important contributor to the global burden of diseases, but the physical and psychopathological risks of recreational drugs misuse are often underestimated and drug-related fatalities in specific settings are under-investigated.
Objectives and methods
In the framework of the EU-funded project “EU-Madness”, we collected and analysed all the reports of drug-related fatalities in Ibiza from January 2010 to September 2016, with the aim of characterising the sample, and identifying the involved substances and the nature of deaths associated with their consumption.
Results
Overall, 58 drug-related fatalities were registered from 2010 to September 2016 (87.9% males, 12.1% females, mean age 33.16; females were significantly younger than males). Most of the deceased were Britons (36.2%), followed by Spanish (22.4%), Italians (6.9%) and Germans (5.2%). In half the cases, the substance identified in post-mortem analyses was a stimulant; in 24.1% of the sample it was a depressor a prescription drug or more than two substances in 22.4%. Most of the fatalities were due to cardiovascular accidents (62%); 22.4% were deaths by drowning, 12% by fall from heights and 3.4% were due to mechanical asphyxia.
Conclusions
According to the results from our sample, stimulants (mainly MDMA and cocaine) are the substances of abuse involved in most drug-caused fatalities. The number of fatalities per year has been steadily increasing, but the growing diffusion of novel psychoactive substances (NPS) does not seem to be a direct cause (although better methods of their analysis in post-mortem samples should be designed).

Stigma towards mental illness has a major impact on the quality of life and the health care of psychiatric patients. Several studies have reported that health professionals have more negative attitudes than general population.
Aims
To explore empathy and attitudes towards mental illness in nursing students (NS) and non-health university students. Our purpose is to see how NS have more empathic and less stigmatizing attitudes towards psychiatric patients, compared to other university students.
Methods
We tested 96 university students (50 NS and 46 non-health university students), with the following questionnaires anonymously filled out:
– Community attitudes towards mental ill (CAMI), to evaluate the different students’ attitudes towards mental illness;
– Empathy quotient (EQ), to assess empathy.
Results
NS differs from the other group in 5 items of CAMI (P < 0.05 in 3 items and P < 0.01 in 2 items), and Authoritarianism subscale (P = 0.023). This shows that NS have a greater general awareness and less stigmatizing attitudes about the need to hospitalize the mentally ill, the difference between psychiatric patients and general population, the wrong need of segregation and the real causes of mental illness. There is also a significant difference in EQ (items 6, 21, 25, 44, 59): future nurses seem to have a slightly higher empathy, even though the EQ total score does not differ in the two groups.
Conclusions
These results suggest that there is a difference with respect to the attitudes towards psychiatric patients in NS and students who do not follow health-care courses: NS have more empathetic and less stigmatizing attitudes.

Stigma towards psychiatry and mental illness significantly worsens the quality of life of psychiatric patients. Negative prejudices in medical students make it difficult for future doctors to send patients to mental health services and promote an increased risk of premature death.
Aims
Our aim is to assess stigma towards mental illness and psychiatry in medical students, and to study the influence of real-world experiences, such as having visited a psychiatric ward, having personally met a psychiatric patient or having friends and/or family members who suffer from a mental illness.
Methods
One hundred and thirteen Italian medical students completed the following tests:
Having visited a psychiatric ward correlates with a better attitude towards psychiatry (P = 0.008), rather than towards the mentally ill. Having personally known someone with mental disorders correlates with less stigmatizing scores in CAMI: total score (P = 0.002), authoritarianism (P < 0.001), benevolence (P = 0.047) and social restriction (P = 0.001). Similar results emerged in those who have close relationships with a psychiatric patient. There is no statistical significance as to empathy.
Conclusions
The students who have visited a psychiatric ward have a less stigmatizing vision of psychiatry, while having personally known psychiatric patients favors a less stigmatizing attitude towards them. Those who have not had this experience, have a more hostile and intolerant vision of mental illness, and consider psychiatric patients as inferior subjects that require coercive attitudes and that would be better to avoid because socially dangerous.

Psychiatric patients often do not receive the same health treatment reserved for patients with no mental disorders. Stigma in mental-health nurses can worsen the patients’ healing time and quality of care.
Objective
To explore the different attitudes towards mental illness and psychiatry in nursing students (NS) of the first and the final year of university, and the importance of having visited a psychiatric ward and having known a psychiatric patient.
Methods
Fifty NS completed the following tests:
– Community attitudes towards mental ill (CAMI);
– Attitudes towards psychiatry (ATP-30);
– Empathy quotient (EQ).
Results
NS of the final year differ significantly from those of the first year in 4 CAMI items, in Authoritarianism subscale (P = 0.041), Social Restrictiveness (P = 0.029) and Community Mental Health Ideology (P = 0.045), indicating a more mature and responsible approach to psychiatric patients, without considering them a threat to be secluded. EQ does not show a significant difference in empathy, not even considering the individual items. Final year NS also have more positive attitudes toward Psychiatry in 3 ATP-30 items and total score (P = 0.01). Those who visited a psychiatric ward have more positive attitudes towards mental illness and Psychiatry, in 6 CAMI items and 3 ATP-30 items. Having personally known a psychiatric patient leads to positive attitudes in only a few CAMI items.
Conclusions
Last-year NS, who have had more direct relationships with patients through practical training, have more empathetic and less stigmatizing attitudes. It is also very useful to attend a psychiatric ward during the nursing training.

Gaia DR2 was released in April 2018 and contains a photometric catalogue of more than 1 billion sources. This release contains colour information in the form of integrated BP and RP photometry in addition to the latest G-band photometry. The level of uncertainty can be as good as 2 mmag with some residual systematics at the 10 mmag level. The addition of colour information greatly enhances the value of the photometric data for the scientific community. A high level overview of the photometric processing, with a focus on the improvements with respect to Gaia DR1, was given. The definition of the Gaia photometric system, a crucial part of the calibration of the photometry, was also explained. Finally, some of the photometric improvements expected for the next data release were described.
We report the utility of whole-genome sequencing (WGS) conducted in a clinically relevant time frame (ie, sufficient for guiding management decision), in managing a Streptococcus pyogenes outbreak, and present a comparison of its performance with emm typing.
SETTING
A 2,000-bed tertiary-care psychiatric hospital.
METHODS
Active surveillance was conducted to identify new cases of S. pyogenes. WGS guided targeted epidemiological investigations, and infection control measures were implemented. Single-nucleotide polymorphism (SNP)–based genome phylogeny, emm typing, and multilocus sequence typing (MLST) were performed. We compared the ability of WGS and emm typing to correctly identify person-to-person transmission and to guide the management of the outbreak.
RESULTS
The study included 204 patients and 152 staff. We identified 35 patients and 2 staff members with S. pyogenes. WGS revealed polyclonal S. pyogenes infections with 3 genetically distinct phylogenetic clusters (C1–C3). Cluster C1 isolates were all emm type 4, sequence type 915 and had pairwise SNP differences of 0–5, which suggested recent person-to-person transmissions. Epidemiological investigation revealed that cluster C1 was mediated by dermal colonization and transmission of S. pyogenes in a male residential ward. Clusters C2 and C3 were genomically diverse, with pairwise SNP differences of 21–45 and 26–58, and emm 11 and mostly emm120, respectively. Clusters C2 and C3, which may have been considered person-to-person transmissions by emm typing, were shown by WGS to be unlikely by integrating pairwise SNP differences with epidemiology.
CONCLUSIONS
WGS had higher resolution than emm typing in identifying clusters with recent and ongoing person-to-person transmissions, which allowed implementation of targeted intervention to control the outbreak.
The generalized theory of terawatt laser pulse interaction with a low-dense porous substance of light chemical elements including laser light absorption and energy transfer in a wide region of parameter variation is developed on the base of the model of laser-supported hydrothermal wave in a partially homogenized plasma. Laser light absorption, hydrodynamic motion, and electron thermal conductivity are implemented in the hydrodynamic code, according to the degree of laser-driven homogenization of the laser-produced plasma. The results of numerical simulations obtained by using the hydrodynamic code are presented. The features of laser-supported hydrothermal wave in both possible cases of a porous substance with a density smaller and larger than critical plasma density are discussed along with the comparison with the experiments. The results are addressed to the development of design of laser thermonuclear target as well as and powerful neutron and X-ray sources.
Synchrotron-based micro-X-ray fluorescence (μXRF) equipment has been used to analyze impurities in polar ice. A customized sample holder has been developed and the μXRF equipment has been adapted with a thermal control system to keep samples unaltered during analyses. Artificial ice samples prepared from ultra-pure water were analyzed to investigate possible contamination and/or experimental artefacts. Analyses of polar ice from Antarctica (Dome C and Vostok) confirm this μXRF technique is non-destructive and sensitive. Experiments can be reproduced to confirm or refine results by focusing on interesting spots such as crystal grain boundaries or specific inclusions. Integration times and resolution can be adjusted to optimize sensitivity. Investigation of unstable particles is possible due to the short analysis time. In addition to identification of elements in impurities, μXRF is able to determine their speciations. The accuracy and reliability of the results confirm the potential of this technique for research in glaciology.
The aim of this study was to investigate the effect of dietary whole dried citrus pulp (DCP) on the antioxidant status of lamb tissues. In total, 17 lambs were divided into two groups and fed for 56 days: a barley-based concentrate diet (CON – eight animals), or a concentrate-based diet including 35% DCP to partially replace barley (CIT – nine animals). The CIT diet contained a double concentration of phenolic compounds than the CON diet (7.9 v. 4.0 g/kg dry matter (DM), respectively), but had no effect (P>0.05) on the overall antioxidant capacity of the hydrophilic fraction of blood plasma, liver and muscle. The CIT diet contained clearly more α-tocopherol than the CON diet (45.7 v. 10.3 mg/kg DM), which could explain the higher concentration of α-tocopherol in liver, plasma and muscle (P<0.05). The dietary treatment had no effect on the extent of lipid peroxidation, measured as thiobarbituric acid and reactive substances assay (TBARS values) in the faeces, small intestine, liver, plasma and muscle. Nevertheless, when muscle homogenates were incubated in the presence of Fe3+/ascorbate to induce lipid peroxidation, the muscle from lambs fed DCP displayed lower TBARS values (P<0.01), which negatively correlated with the concentration of α-tocopherol in muscle. These results showed that feeding whole DCP to ruminants increases the antioxidant status of muscle through an increase in the deposition of α-tocopherol.
Pellets made of pure sodalite blended with commercial glass frit and pellets made
of sodalite, glass frit and a mixture of chloride salts, synthesized through dry
pressing and subsequent thermal treatment, were evaluated as a potential matrix
for confinement of spent chloride salts coming from pyroprocesses. The sodalite
pellets were leached at 23°C and 90°C for 28 days, according
to the ASTM C1220-10 procedure. Normalized release rates were estimated for the
following elements: Li, Na, Al, Si, K, Rb, Cs, Sr, Ba, La, Nd and compared with
literature results. SEM investigations, carried out before and after the
leaching tests, show dissolution and re-precipitation phenomena at
90°C.
Direct numerical simulations of turbulent channel flows at friction Reynolds numbers (Re) of 550, 1000 and 1500 are used to analyse the turbulent production, transfer and dissipation mechanisms in the compound space of scales and wall distances by means of the Kolmogorov equation generalized to inhomogeneous anisotropic flows. Two distinct peaks of scale-energy source are identified. The first, stronger one, belongs to the near-wall cycle. Its location in the space of scales and physical space is found to scale in viscous units, while its intensity grows slowly with $\mathit{Re}$, indicating a near-wall modulation. The second source peak is found further away from the wall in the putative overlap layer, and it is separated from the near-wall source by a layer of significant scale-energy sink. The dynamics of the second outer source appears to be strongly dependent on the Reynolds number. The detailed scale-by-scale analysis of this source highlights well-defined features that are used to make the properties of the outer turbulent source independent of Reynolds number and wall distance by rescaling the problem. Overall, the present results suggest a strong connection of the observed outer scale-energy source with the presence of an outer region of turbulence production whose mechanisms are well separated from the near-wall region and whose statistical features agree with the hypothesis of an overlap layer dominated by attached eddies. Inner–outer interactions between the near-wall and outer source region in terms of scale-energy fluxes are also analysed. It is conjectured that the near-wall modulation of the statistics at increasing Reynolds number can be related to a confinement of the near-wall turbulence production due to the presence of increasingly large production scales in the outer scale-energy source region.
The development of high-intensity lasers has opened the field of nuclear reactions initiated by laser-accelerated particles. One possible application is the production of aneutronic fusion reactions for clean fusion energy production. We propose an innovative scheme based on the use of two targets and present the first results obtained with the ELFIE facility (at the LULI Laboratory) for the proton–boron-11 (p–11B) fusion reaction. A proton beam, accelerated by the Target Normal Sheat Acceleration mechanism using a short laser pulse (12 J, 350 fs, 1.056 µm, 1019 W cm−2), is sent onto a boron target to initiate fusion reactions. The number of reactions is measured with particle diagnostics such as CR39 track-detectors, active nuclear diagnostic, Thomson Parabola, magnetic spectrometer, and time-of-flight detectors that collect the fusion products: the α-particles. Our experiment shows promising results for this scheme. In the present paper, we discuss its principle and advantages compared with another scheme that uses a single target and heating mechanisms directly with photons to initiate the same p–11B fusion reaction.
