Introduction
Negative symptoms has been classically associated with cognition, psychosocial functioning and quality of life in patients with schizophrenia. But negative symptoms are not a unitary construct, encompassing two different factors: diminished expression, and motivation and pleasure. Few works have studied the relationship between these two different negative symptoms factors and cognition (neuro and social cognition), psychosocial functioning and quality of life, jointly, in patients with a first psychotic episode of schizophrenia.
ObjectivesThe objective of the present work was to study, in a sample of patients with a first psychotic episode of schizophrenia, the relationship between the negative symptoms (diminished expression and motivation and pleasure) and neurocognition, social cognition, functioning and quality of life.
MethodsThe study was carried out with 82 outpatients with a first psychotic episode of schizophrenia from two Spanish hospitals (“12 de Octubre” University Hospital, Madrid and “Virgen de la Luz” Hospital, Cuenca). The patients were assessed with the Clinical Assessment Interview for Negative Symptoms (CAINS) for evaluating diminished expression (EXP) and motivation and pleasure (MAP) symptoms, the MATRICS Consensus Cognitive Battery (MCCB) for evaluating neurocognition and social cognition, the Social and Occupational Functioning Assessment Scale (SOFAS), and the Quality of Life Scale (QLS).
ResultsA negative correlation was found between neurocognition and the two negative symptoms subscales: CAINS-EXP (r=-0.458, p<0.001) and CAINS-MAP (r=-0.374, p<0.001); but with social cognition only CAINS-EXP was correlated (r=-0.236, p=0.033). Also, it was found a high negative correlation between SOFAS scores and CAINS-MAP (r=-0.717, p<0.001); and a medium negative correlation with CAINS-EXP (r=-0.394, p<0.001). Finally, QLS score was high correlated with both CAINS subscales: CAINS-EXP (r=-0.681, p<0.001) and CAINS-MAP (r=-0.770, p<0.001).
ConclusionsThis study found a relationship between negative symptoms and neurocognition, social cognition, functioning and quality of life in a sample of patients with a first psychotic episode of schizophrenia. But the two different negative symptom factors, diminished expression, and motivation and pleasure, are associated differently with psychosocial functioning, but especially with social cognition where the relationship was only found with diminished expression symptoms.

Introduction
The compassionate use of intranasal esketamine is approved in Spain for treatment-resistant depression (TRD).
ObjectivesThe objective of the study is to assess the clinical stability in the medium-term follow-up of patients with TRD after esketamine use.
MethodsDescriptive, retrospective and multicenter study carried out in Spain. Patients with TRD who had received esketamine treatment, and for whom there were clinical data of subsequent evolution, were included. The scores on the MADRS and Hamilton scales were changed into scores on the CGI scale according to the studies by Leucht et al. The Student’s t test was performed to assess differences in the CGI.
ResultsEleven patients were included: 72.7% were women and the mean age was 56 (SD: 12.9). The maximum dose of esketamine used was 84mg in 63.7%. The onset of antidepressant action was observed from the 1st dose in 72.6% of the patients. The mean time in treatment was 6.6 months (SD: 2.3) and 90.9% reached remission criteria. After 7.4 months (SD: 3.0) from the end of the treatment, 90.9% remained in remission and without visits to the emergency room or hospitalization for psychiatric reasons. The mean baseline score on the CGI-SI was 5.7 points, at the end of the treatment was 1.2 points and after longitudinal follow-up it was 1. Statistically significant differences were observed (p<0.001) both at the end of the treatment and in the post-esketamine follow-up compared with baseline score.
ConclusionsIn our sample, the use of esketamine in TRD shows clinical stability in the medium-term follow-up.

Introduction
Case of a 17yo patient with high functioning ASD and OCD with obsessions about being a pedophile, with suicidal ideation and self-harming behaviors. He was followed in outpatient care for one year since his first contact with Mental Health, following an inpatient admission for suicidal ideation.
ObjectivesDifferential diagnosis between OCD, ASD and possible pedophilia. Learn about different levels of care involved, and other possibilities. Therapy resources used.
MethodsDescription of the case report: description of initial and final Mental Status Exam Differential Diagnosis: ASD vs OCD vs Pedophilia vs Depressive Disorder Children’s Yale-Brown Obsessive Compulsive Scale Therapy: family based therapy, and Exposure response prevention therapy.
ResultsIntrusive images, and reassurance seeking, helped with OCD diagnosis. ASD made symptoms harder to manage with SSRIs alone, which drove to add Aripiprazol at low doses in outpatient care. CY-BOCS showed obsessions other than doubts about being a pedophile. He participated in Exposure response prevention therapy with response, especially when antipsychotic medication was added. Family based therapy worked with his parents in not providing excessive reassurance, and with the patient in gaining insight about his OCD. Decreased anxiety, decreased self-deprecation and no new suicidal thoughts Functionality of the patient in the community improved, with possibility of going college next year.
ConclusionsRecommendation of good assessment of sexuality in ASD population Importance of individual and family therapy for OCD and specially when there is poor judgement and insight in the patient. Importance of combined treatment: pharmacology + therapy

Introduction
Suicide causes 1.4% of deaths worldwide. Twenty times more frequent, suicide attempts entail an important source of disability and of psychosocial and medical resources use.
ObjectiveTo describe main socio-demographical and psychiatric risk factors of suicide attempters treated in a general hospital's emergency room basis.
AimsTo identify individual features potentially useful to improve both emergency treatments and resource investment.
MethodsA descriptive study including data from 2894 patients treated in a general hospital's emergency room after a suicidal attempt between years 2006 and 2014.
ResultsSixty-nine percent of the population treated after an attempted suicide were women. Mean age was 38 years old. Sixty-six percent had familiar support; 48.5% had previously attempted a suicide (13% did not answer this point); 72.6% showed a personal history of psychiatric illness. Drug use was present in 38.3% of the patients (20.3% did not answer this question); 23.5% were admitted to an inpatient psychiatric unit. Medium cost of a psychiatric hospitalization was found to be 4900 euros.
ConclusionThis study results agree with previously reported data. Further observational studies are needed in order to bear out these findings, rule out potential confounders and thus infer and quantify causality related to each risk factor.

Introduction: The quality of life of children with sickle cell disease (SCD) depends on the severity, timing and number of painful episodes (vaso-occlusive crises, VOC) and their need for medical treatment and hospitalizations. The objective of this study was to explore the experiences of pediatric patients and their families during VOC. Methods: This qualitative study used semi-structured one-on-one and focus group interviews, designed in partnership with two patients and one parent, in a single center, tertiary care pediatric university-affiliated hospital. Two groups of participants were interviewed independently: (1) adolescent patients aged 12 to 18 years old hospitalised within the last 2 years for VOC, (2) parents of pediatric patients with SCD hospitalised within the last 2 years for VOC. Data was transcribed in full and analysed using NVivo12. Descriptive thematic content analysis was performed by coding themes emerging from data. After validating codes through interjudge assessment by consensus, themes from teenagers’ and parent's discourses were systematically compared for the final analysis. Results: Between June and August 2018, 8 interviews were conducted. 10 parents and 5 adolescents participated. Teenagers’ and parents’ answers mirrored each other's. Prompt pain relief was crucial, although the side effects of pain relief medications used were an added source of suffering. Recent quality improvement initiatives such as standardised order sheets were noteworthy improvements, though personalizing care to each patient's with pharmacological and non-pharmacological methods was also important to participants. Given the unpredictability and severity of VOC, their impact on both patients’ and families’ lives were substantial, as was the long term emotional burden. Parents felt guilty given the hereditary nature of the disease, they encouraged neonatal and prenatal testing, and they sought definitive treatments for both VOC and SCD. Tensions within parent-teenager relationships were described centered on developing autonomy and protecting the child to improve adherence to treatments. Conclusion: Participants emphasized the need to provide timely adequate analgesia, through both standardised quality improvement initiatives and a personalised approach to analgesia. Understanding the impact of VOC on patients’ lives and their socio-familial context is important to tailor clinical interventions.

Recent studies suggest that the use of vegetable oils at expense of fish oil in aquaculture feeds might have potential negative effects on fish redox homeostasis and adiposity. Resveratrol (RESV) is a lipid-soluble phytoalexin present in fruits and vegetables with proven in vivo antioxidant function in animals. The present study aims to assess the potential use of RESV in Atlantic salmon feeds. To this end, post-smolt salmons with an initial BW of 148±3 g were fed four experimental diets for 15 weeks. A diet low in fish oil served as a control and was supplemented with 0, 0.5, 1.5 and 2.5 g/kg of RESV, respectively. The effect of the experimental diets on animal performance, tissue fatty acid composition, and the expression of genes encoding proteins involved in antioxidant signalling, lipid peroxidation, and metabolism were studied. Resveratrol significantly reduced feed intake and final BW of the salmon. Feeding RESV did not affect the sum of saturated and monounsaturated fatty acids or total lipids in the fillet. While the content of total polyunsaturated fatty acids was not affected, the percentages of some fatty acids in the liver and fillet were changed by RESV. Furthermore, in liver, the relative expression of glutathione peroxidase 4b, nuclear factor-like 2, and arachidonate 5-lipoxygenase remained unchanged across treatment groups. In conclusion, the negative impact of dietary RESV on FI and hence reduction of the BW discourages its inclusion in low fish oil diets for Atlantic salmon.

A new generation of solar instruments provides improved spectral, spatial, and temporal resolution, thus facilitating a better understanding of dynamic processes on the Sun. High-resolution observations often reveal multiple-component spectral line profiles, e.g., in the near-infrared He i 10830 Å triplet, which provides information about the chromospheric velocity and magnetic fine structure. We observed an emerging flux region, including two small pores and an arch filament system, on 2015 April 17 with the ‘very fast spectroscopic mode’ of the GREGOR Infrared Spectrograph (GRIS) situated at the 1.5-meter GREGOR solar telescope at Observatorio del Teide, Tenerife, Spain. We discuss this method of obtaining fast (one per minute) spectral scans of the solar surface and its potential to follow dynamic processes on the Sun. We demonstrate the performance of the ‘very fast spectroscopic mode’ by tracking chromospheric high-velocity features in the arch filament system.

Background
It is well known that web-based interventions can be effective treatments for depression. However, dropout rates in web-based interventions are typically high, especially in self-guided web-based interventions. Rigorous empirical evidence regarding factors influencing dropout in self-guided web-based interventions is lacking due to small study sample sizes. In this paper we examined predictors of dropout in an individual patient data meta-analysis to gain a better understanding of who may benefit from these interventions.
MethodA comprehensive literature search for all randomized controlled trials (RCTs) of psychotherapy for adults with depression from 2006 to January 2013 was conducted. Next, we approached authors to collect the primary data of the selected studies. Predictors of dropout, such as socio-demographic, clinical, and intervention characteristics were examined.
ResultsData from 2705 participants across ten RCTs of self-guided web-based interventions for depression were analysed. The multivariate analysis indicated that male gender [relative risk (RR) 1.08], lower educational level (primary education, RR 1.26) and co-morbid anxiety symptoms (RR 1.18) significantly increased the risk of dropping out, while for every additional 4 years of age, the risk of dropping out significantly decreased (RR 0.94).
ConclusionsDropout can be predicted by several variables and is not randomly distributed. This knowledge may inform tailoring of online self-help interventions to prevent dropout in identified groups at risk.

In this study we analyze the electrical behavior of a junction formed by an ultraheavily Ti implanted Si layer processed by a Pulsed Laser Melting (PLM) and the non implanted Si substrate. This electrical behavior exhibits an electrical decoupling effect in this bilayer that we have associated to an Intermediate Band (IB) formation in the Ti supersaturated Si layer. Time-of-flight secondary ion mass spectrometry (ToF-SIMS) measurements show a Ti depth profile with concentrations well above the theoretical limit required to the IB formation. Sheet resistance and Hall mobility measurements in the van der Pauw configuration of these bilayers exhibit a clear dependence with the different measurement currents introduced (1µA-1mA). We find that the electrical transport properties measured present an electrical decoupling effect in the bilayer as function of the temperature. The dependence of this effect with the injected current could be explained in terms of an additional current flow in the junction from the substrate to the IB layer and in terms of the voltage dependence in the junction with the measurement current.

Summary
Abstract
A celebrated theorem of Kegel and Wielandt asserts the solubility of a finite group which is the product of two nilpotent subgroups. In this survey we report on some extensions of this result by considering π-decomposable subgroups, for a set of primes π, instead of nilpotent groups.
Introduction
The study of groups which can be factorised as the product of two subgroups has developed extensively in recent decades. The general aim is to obtain information about the structure of the whole group from the structure of the subgroups in the factorization, and vice versa. An example is the well known theorem of Kegel and Wielandt which establishes the solubility of a finite group factorised as the product of two nilpotent subgroups. This result has been the motivation for a wide variety of results in the literature. In particular some of them consider the situation when either one or both of the factors are π-decomposable, for a set of primes π. This paper is a survey article containing a detailed account of recent achievements which extend the Kegel–Wielandt theorem in this direction.
Only finite groups are considered in this paper.
Let us start with an explicit statement of the starting point of our development:
Theorem 1.1 (Kegel [14] and Wielandt [19])If the group G = AB is the product of two nilpotent subgroups A and B, then G is soluble.

Hull cleaning before repainting is a key operation in the maintenance of ships. For more than a decade, a means to improve this operation has been sought through robotization and the use of different techniques such as grit blasting and ultra high pressure water jetting. Despite this, it continues to be standard practice in shipyards that this process is carried out manually. This paper presents a family of robots that aims to offer important improvements to the process as well as satisfying, to a great extent, all the operative requirements of efficiency, security, and respect for the environment that shipyards nowadays demand. It is described the family of devices with emphasis on the mechanical design. This set consists of two vertical robotic towers and a robot climber. In addition, it is shown the control architecture of the global system. Finally, operative results are presented together with a comparison between the performance achieved in shipyards through the use of these robots and those obtained with a manual process.

The aim of this study was to identify a fluorescence parameter whose estimate could be used reliably for a drought tolerance test in durum wheat (Triticum durum). Twenty-five cultivars were grown in a glasshouse over two seasons (1987/88 and 1988/89) at Foggia, Southern Italy. Photochemical and non-photochemical quenching (qQ and qE), the half time of fluorescence decay (tP½) and the initial slope of fluorescence decay (ISPS) were measured on control and dehydrated pre-darkened excised leaves; qQ and qE were measured twice: first at 14 s after actinic illumination and second at the steady state.
No great difference in qQ and qE was apparent between control and dehydrated leaves at the steady state; however, at 14 s after illumination there was a decrease in qQ and in ISPS and an increase in tP½ in dehydrated leaves. The predictive capability of fluorescence parameters was assessed by comparison with a yield-based drought susceptibility index (DSI). The percentage decrease in qQ at 14 s showed the highest correlation with DSI (r = 0·75, significant at P < 0·001), so it may be considered a good indicator of drought tolerance in durum wheat. Results obtained at different developmental stages with different fluorescence levels (Fo, P and Fm) and parameters (qQ, qE and tP½) indicated that for maximum reliability the test must be applied at the vegetative phase.

The chlorophyll fluorescence parameters ΔF/Fm′ and Fv′/Fm′, related respectively to the quantum yield of photosynthetic electron transport and to the efficiency of excitation capture by the open centres of photosystem II, have been evaluated as possible indicators of drought tolerance in durum wheat. ΔF/Fm′ and Fv′/Fm′ measurements were carried out on excised leaves, both control and dehydrated, of 25 cultivars. ΔF/Fm′ and Fv′/Fm′ values were obtained at two times after the start of fluorescence measurement: at 14 s, i.e. during the induction curve (ΔF/Fm′14s and Fv′/Fm′14s) and at 200s, i.e. at steady state fluorescence (ΔF/Fm′200s and Fv′/Fm′200s).
In dehydrated leaves a mean significant decrease of 20% (P < 0·001) was observed in ΔF/Fm′14s values. In contrast, no great differences were observed between control and dehydrated leaves with regard to ΔF/Fm′200s, Fv′/Fm′14s and Fv′/Fm′200s.
The percentage decrease of ΔF/Fm′14s after dehydration was correlated with the drought susceptibility index (DSI) of the cultivars, evaluated on a yield basis and a significant correlation (r = 0·72, P < 0·001) was found.

A large outbreak of hepatitis A virus (HAV) infection occurred in 2004 in Campania, a region of southern Italy, with 882 cases reported between 1 January and 1 August. The local public health authorities and the Italian National Institute of Health carried out investigations in order to characterize the agent, identify the source of infection and the route of transmission, and implement appropriate control measures. A web-based reporting system enhanced the flow of information between public health authorities, providing real-time epidemic curves and frequency distributions. The same 1B HAV genotype was found in 90% of sera from a subset of patients with acute disease, suggesting a local common source. A case-control study in the municipality with the highest attack rate showed that raw seafood consumption, in particular if illegally sold in water, was strongly associated with HAV illness. Samples of seafood systematically collected from retailers were found contaminated by HAV.

Background: The aim of this study was to determine the prevalence of dementia in a socioeconomically disadvantaged population of older adults living in the city of São Paulo, Brazil.
Methods: A cross-sectional one-phase population-based study was carried out among all residents aged ≥ 65 in defined census sectors of an economically disadvantaged area of São Paulo. Identification of cases of dementia followed the protocol developed by the 10/66 Dementia Research Group.
Results: Of 2072 individuals in the study, 105 met the criteria for a diagnosis of dementia, yielding a prevalence of 5.1%. Prevalence increased with age for both men and women after age 75 years, but was stable from 65 to 74 years. Low education and income were associated with increased risk of dementia.
Conclusions: The prevalence of dementia among older adults from low socioeconomic backgrounds is high. This may be partly due to adverse socioeconomic conditions and consequent failure to compress morbidity into the latter stages of life. The increasing survival of poorer older adults with dementia living in developing countries may lead to a rapid increase in the prevalence of dementia worldwide.

Summary
Introduction
This paper is a survey article containing an up-to-date account of recent achievements regarding embedding properties in direct products of groups. In the last years, several authors are carrying out a systematic study with the aim of understanding how subgroups with various embedding properties can be detected and characterized in the subgroup lattice of a direct product of two groups in terms of the subgroup lattices of the two groups.
Unless otherwise stated all groups considered in this paper are finite.
Direct products are maybe the easiest way to construct new groups from given ones and in spite of the simplicity of this construction, their structures are sometimes surprising.
The subgroup structure of direct products is well-known by a classical result due to Goursat. In this paper G1 × G2 = {(g1, g2) | gi ∈ Gi, i = 1, 2} will always denote the direct product of the groups G1 and G2 and πi will denote the canonical projection πi : G1 × G2 → Gi, for i = 1, 2. For a subgroup U of G1 × G2:
πi (U) = UGj ∩ Gi, {i, j} = {1, 2},
U ∩ Gi ⊴ πi (U), for i = 1, 2.
Goursat's theorem states that, apart from the direct product of subgroups of the direct factors, only ‘diagonal’ subgroups appear in a direct product.

The magnetism of CoRh nanoparticles (NPs) is investigated experimentally and theoretically. NPs of about 2 nm diameter have been synthesized by decomposition of organometallic precursors in mild conditions of pressure and temperature, under hydrogen atmosphere and in the presence of a polymer matrix. The magnetic properties are determined by SQUID and X-ray magnetic circular dichroism. All the studied CoRh clusters are magnetic with an average spin moment per atom that is significantly larger than the one of macroscopic crystals or alloys with similar concentrations. The experimental results and the comparison with theory suggest that the most likely chemical arrangement is a Rh core with a Co-rich outer shell and some degree of intermixing at the CoRh interface. A detailed analysis of the theoretical results from a local perspective shows that the spin and orbital moments of the Co and Rh atoms at the interface are largely responsible for the enhancement of the magnetization.
