Psychotic disorders, particularly schizophrenia, are severe mental illnesses associated with high rates of disability and functional impairment, causing significant individual burden and incurring high societal costs. Typical onset of schizophrenia is in late adolescence or early adulthood and the complex management requires often life-long pharmacological and non-pharmacological treatment. Early symptom recognition and timely intervention can improve the course of illness and result in better outcome and prognosis, effective management leads to a functional recovery. However, recent reports have identified significant gaps in access to timely assessment and shared decision-making interventions, with inadequate care pathways. In the face of an unprecedented demand for mental healthcare for young people, it can be challenging for health services to deliver high-quality mental healthcare which, according to the World Health Organization, should be timely, effective and evidence-based, safe and person-centered. The project covers nine countries in Europe.
Objectives
Building on the European Brain Council Rethinking Schizophrenia Beyond The Voices Policy Report (2024), the survey and literature review aim to: (1) evaluate the effectiveness of integrated models of youth mental healthcare on a broader range of outcomes, including both mental health outcomes, such as clinical symptoms, functioning and quality of life and health service outcomes, including access and satisfaction with care in young people; and (2) identify the common components of integrated care pathways for young people with first episode psychosis.
Methods
Using the care pathway as a tool at the first step of the research, a cross-country survey was co-designed with the Board of experts and anonymously launched earlier this year. By complementing the survey, the literature review on the care pathway will address quality and continuity of care from the first onset of psychosis and schizophrenia to long-term care in the selected countries including existing guidelines and overview country health situation assessments.
Results
Patients and mental health professionals’ insights will be collected. Obtained data will also be analysed by the stakeholders and used to formulate recommendations for policy makers, care payers, mental health professionals, patients and their families (both country specific and at the EU level).
Conclusions
A policy report, based on the consensus, will be released at the Brain Awareness Week 2025 with results and recommendations which will provide valuable insight into understanding the needs of patients with first-episode psychosis and defining the optimal care pathways to engage with them. In order to show that there is a progress in the field of care for schizophrenia patients, the utilization of new technologies is included.
Bipolar disorder is a chronic mental health condition characterized by alternating periods of mania, depression, and mixed states. The timing and recurrence of these mood episodes may be influenced by external factors, including seasonal variations. Previous research has highlighted potential seasonal patterns in the onset of manic episodes, with environmental factors such as changes in light exposure, temperature, and circadian rhythms playing a role. Comprehending these temporal patterns is paramount, as they provide critical insights into the underlying mechanisms of mood dysregulation and can inform the development of more targeted and effective clinical interventions for individuals with bipolar disorder.
Objectives
The primary objective of this study is to determine whether manic and mixed episodes in bipolar disorder show a seasonal pattern. Specifically, this study aims to investigate whether specific times of the year are associated with a heightened incidence of hospitalizations for manic or mixed episodes.
Methods
A retrospective analysis was conducted on patient records from an inpatient psychiatric unit over four years. Inclusion criteria were a primary diagnosis of bipolar disorder and admission due to a manic or mixed episode. Data were categorized by month and season of hospitalization, and statistical analyses were performed to assess for significant seasonal variations.
Results
Our study revealed a significant increase in hospitalizations for manic episodes during the spring and summer months, with 58% of manic episodes occurring during this period, and a secondary peak in autumn. Mixed episodes demonstrated less pronounced but still observable seasonal variation. Statistical analysis confirmed the presence of seasonality, with manic episodes more likely to occur during periods of increased daylight, while mixed episodes appeared more distributed across the year.
Conclusions
The findings indicate that manic episodes in bipolar disorder follow a distinct seasonal pattern, peaking in spring and summer. Although mixed episodes are less strongly correlated with seasonality, some seasonal trends were observed. These results highlight the significance of considering environmental and seasonal factors in the management of bipolar disorder. Further investigation into the underlying mechanisms of these patterns could improve preventative care and inform the development of personalized treatment strategies.
When an evaporating water droplet is deposited on a thermally conductive substrate, the minimum temperature will be at the apex due to evaporative cooling. Consequently, density and surface tension gradients emerge within the droplet and at the droplet–gas interface, giving rise to competing flows from, respectively, the apex towards the contact line (thermal-buoyancy-driven flow) and the other way around (thermal Marangoni flow). In small droplets with diameter below the capillary length, the thermal Marangoni effects are expected to dominate over thermal buoyancy (‘thermal Rayleigh’) effects. However, contrary to these theoretical predictions, our experiments show mostly a dominant circulation from the apex towards the contact line, indicating a prevailing of thermal Rayleigh convection. Furthermore, our experiments often show an unexpected asymmetric flow that persisted for several minutes. We hypothesise that a tiny amount of contaminants, commonly encountered in experiments with water/air interfaces, act as surfactants and counteract the thermal surface tension gradients at the interface and thereby promote the dominance of Rayleigh convection. Our finite element numerical simulations demonstrate that under our specified experimental conditions, a mere 0.5 % reduction in the static surface tension caused by surfactants leads to a reversal in the flow direction, compared to the theoretical prediction without contaminants. Additionally, we investigate the linear stability of the axisymmetric solutions, revealing that the presence of surfactants also affects the axial symmetry of the flow.
Evidence consistently shows that the benefits Nature-based Solutions generate are determined by several individual characteristics such as gender, age, sexuality, ethnicity and disability. As a result, Nature-based Solutions can perpetuate existing inequalities and even create new inequalities partly because diverse minority and marginalized people are underrepresented in the process of designing and implementing Nature-based Solutions. Therefore, some Nature-based Solutions scholars have highlighted the necessity to actively involve diverse minority and marginalized groups into the co-creation processes of Nature-based Solutions and to investigate who benefits from the Nature-based Solution and why. Within the GoGreenRoutes H2020 project a transdisciplinary gender, inclusion and diversity panel was established in order to map existing challenges within the consortium. Concordantly, relevant scientific resources and policy documents were identified. Both were blended during consensus meetings in order to develop a common understanding leading to a theoretical gender, inclusion and diversity framework. This framework consists of five domains: (1) gender equality; (2) LGBTQI + rights; (3) social, cultural and ethnic background; (4) people with disabilities; (5) integration of refugees and immigrants; and (6) intergenerational perspectives. Further, the framework was operationalized through the development of a checklist for researchers and practitioners.
This study examined the incorporation of benzalkonium chloride into palygorskite and montmorillonite, assessing their potential as drug carriers. The aim was to evaluate the use of both clay minerals as viable options for antibacterial drug delivery. Various amounts (0.5, 1.0 and 2.0 times the cation-exchange capacity) of benzalkonium chloride were incorporated into both clay minerals, and the resulting materials were characterized using Fourier-transform infrared spectroscopy, thermogravimetric analysis, X-ray diffraction and elemental analysis using both CHNS-O elemental analysis and energy-dispersive X-ray spectroscopy. The Fourier-transform infrared spectroscopy and elemental analysis results indicate that benzalkonium chloride was incorporated successfully into the clay minerals. The X-ray diffraction traces of organo-montmorillonite indicate that the d-value increased as benzalkonium chloride content increased, confirming the intercalation of benzalkonium chloride within the montmorillonite interlayer space. By contrast, this behaviour was not observed for palygorskite. For the benzalkonium chloride-release studies, an initial burst release was found within the first 5 h, followed by a sustained release of benzalkonium chloride during the remaining testing time (24 h). Drug-release profiles were similar for modified palygorskite or montmorillonite during the testing time (24 h). Both clay minerals modified with benzalkonium chloride are promising materials for use as antibacterial fillers for several applications, including in the dental care industry.
Besides the traditionally studied group of young females, disordered eating occurs in all age groups (Eedena, Hoekena, and Hoek 2021). In recent years, there has been an increase in the prevalence of eating disorders and symptoms in middle-aged and older women (40 years old and over) (Mangweth-Matzek and Hoek 2017).
Experts in eating psychopathology in special groups such as Samuels, Maine and Taltillo (2019) suggest the use of the Screen for Disordered Eating (SDE; Magen et al. 2018) in the psychometric assessment of women in middle age and older. The SDE was developed to allow the Eating Disorders (ED) screening in Primary Health Care in people of all ages and without excluding Binge Eating Disorder (BED).
The SDE is composed of five items (yes or no answers), extracted from other validated self-reported questionnaires for the assessment of eating psychopathology.
Objectives
To analyze the psychometric properties of the Portuguese Version of the Screen for Disordered Eating in a sample of women from the general population aged 40 and over.
Methods
Participants were 516 women with a mean age of 50.28 of years old (± 8.063; range: 40-80). They answered an online survey including the preliminary Portuguese version of the SDE and the Portuguese version of the Eating Disorder Examination – Questionnaire (EDE-Q-7; Pereira et al. 2021).
Results
Confirmatory Factor Analysis showed that the unidimensional model presented good fit indexes (χ2/df=1.502; RMSEA=.0311, p<.001; CFI=.987 TLI=.995, GFI=.965). The Cronbach’s alfa was .762. All the items contributed to the internal consistency, as they presented item-total correlations above .40 and the exclusion of each one would decrease the alpha. Pearson correlations between SDE and the EDE-Q-7 were significant (p<.01), positive and moderate/high, as follows: .516 with the total score and .318, .503 and .536 respectively with the dimensional scores of Dietary restraint, Shape/weight overvaluation and Body dissatisfaction.
Conclusions
As observed with the original English-language scale, the Portuguese version of the SDE has shown good validity (construct and concurrent) and internal consistency. As such, the SDE might be a useful tool to investigate disordered eating psychopathology in older women. In the near future we will determine the SDE cut-offs with the best combination of sensitivity and specificity to screen for eating disorders in this populational group.
Contact heat is commonly used in experimental research to evoke brain activity, most frequently acquired with electroencephalography (EEG). Although magnetoencephalography (MEG) improves spatial resolution, using some contact heat stimulators with MEG can present methodological challenges. This systematic review assesses studies that utilise contact heat in MEG, their findings and possible directions for further research.
Methods:
Eight electronic databases were searched for relevant studies, in addition to the selected papers' reference lists, citations and ConnectedPapers maps. Best practice recommendations for systematic reviews were followed. Papers met inclusion criteria if they used MEG to record brain activity in conjunction with contact heat, regardless of stimulator equipment or paradigm.
Results:
Of 646 search results, seven studies met the inclusion criteria. Studies demonstrated effective electromagnetic artefact removal from MEG data, the ability to elicit affective anticipation and differences in deep brain stimulation responders. We identify contact heat stimulus parameters that should be reported in publications to ensure comparisons between data outcomes are consistent.
Conclusions:
Contact heat is a viable alternative to laser or electrical stimulation in experimental research, and methods exist to successfully mitigate any electromagnetic noise generated by PATHWAY CHEPS equipment – though there is a dearth of literature exploring the post-stimulus time window.
Animal hoarding is considered to be an under-reported problem, which affects the welfare of both people and animals. Few published studies on animal hoarding are available in the scientific literature, particularly outside North America. The present study was designed to obtain data on animal hoarding in Spain, with a particular focus on animal welfare issues. Data were obtained retrospectively from 24 case reports of animal hoarding involving a total of 1,218 dogs and cats and 27 hoarders. All cases were the result of legal intervention by a Spanish humane society during the period from 2002 to 2011. Hoarders could be characterised as elderly, socially isolated men and women who tended to hoard only one species (dog or cat). Most cases presented a chronic course of more than five years of animal hoarding. The average number of animals per case was 50, with most animals being dogs. In 75% of cases the animals showed indications of poor welfare, including poor body condition, and the presence of wounds, parasitic and infectious illnesses. Amongst the hoarded animals aggression and social fear were the most commonly reported behaviours. To the authors’ knowledge, this is the first report on animal hoarding in Spain and one of the first in Europe. Further studies are needed to fully elucidate the epidemiology, cross-cultural differences and aetiology of this under-recognised public health and welfare problem. More research might help to find efficient protocols to assist in the resolution and prevention of this kind of problem.
Observational studies suggest that 25-hydroxy vitamin D (25(OH)D) concentration is inversely associated with pain. However, findings from intervention trials are inconsistent. We assessed the effect of vitamin D supplementation on pain using data from a large, double-blind, population-based, placebo-controlled trial (the D-Health Trial). 21 315 participants (aged 60–84 years) were randomly assigned to a monthly dose of 60 000 IU vitamin D3 or matching placebo. Pain was measured using the six-item Pain Impact Questionnaire (PIQ-6), administered 1, 2 and 5 years after enrolment. We used regression models (linear for continuous PIQ-6 score and log-binomial for binary categorisations of the score, namely ‘some or more pain impact’ and ‘presence of any bodily pain’) to estimate the effect of vitamin D on pain. We included 20 423 participants who completed ≥1 PIQ-6. In blood samples collected from 3943 randomly selected participants (∼800 per year), the mean (sd) 25(OH)D concentrations were 77 (sd 25) and 115 (sd 30) nmol/l in the placebo and vitamin D groups, respectively. Most (76 %) participants were predicted to have 25(OH)D concentration >50 nmol/l at baseline. The mean PIQ-6 was similar in all surveys (∼50·4). The adjusted mean difference in PIQ-6 score (vitamin D cf placebo) was 0·02 (95 % CI (−0·20, 0·25)). The proportion of participants with some or more pain impact and with the presence of bodily pain was also similar between groups (both prevalence ratios 1·01, 95 % CI (0·99, 1·03)). In conclusion, supplementation with 60 000 IU of vitamin D3/month had negligible effect on bodily pain.
Pregnancy and the postpartum are generally characterized by positive feelings and expectations but they may also disguise maternal stress and difficulties. These are typical periods for the onset or relapse of psychiatric symptoms and disorders. Even though suicide during pregnancy and postpartum is rare, it is among the leading causes of maternal perinatal mortality.
Objectives
To provide an overview on the risk of suicide during pregnancy and postpartum.
Methods
PubMed database was searched using combinations of the terms “suicide”, combined with “pregnancy” and “depression”.
Results
The major risk factors for suicidal ideation are previous suicide attempts, self-harm, current or past history of psychiatric disorder, young maternal age, being unmarried, an unplanned pregnancy, substance use disorders, lack effective psychosocial support and discontinuation of psychotropic drugs. Pregnant women with suicidality behavior have also an increased risk for various adverse obstetric outcomes, including miscarriage, preterm delivery, maternal hemorrhage, and stillbirth. Furthermore, the postpartum period is often associated with the onset of mood and psychotic disorders with an increased risk of both suicide and infanticide. Women who have suffered from serious psychiatric conditions either after childbirth or in other phases of life should be informed about the possibility of relapse after subsequent pregnancies, thus presenting a higher risk of suicide.
Conclusions
During pregnancy and postpartum, it is fundamental to investigate suicide risk, including suicidal ideation, thoughts, and intent, especially (but not only) in women affected by mental pathology. Moreover, maternal suicide behaviour affects the child’s neuropsychological development and can also increase the infant´s suicide risk.
Despite the multitude of clinical manifestations of post-acute sequelae of SARS-CoV-2 infection (PASC), studies applying statistical methods to directly investigate patterns of symptom co-occurrence and their biological correlates are scarce.
Methods
We assessed 30 symptoms pertaining to different organ systems in 749 adults (age = 55 ± 14 years; 47% female) during in-person visits conducted at 6–11 months after hospitalization due to coronavirus disease 2019 (COVID-19), including six psychiatric and cognitive manifestations. Symptom co-occurrence was initially investigated using exploratory factor analysis (EFA), and latent variable modeling was then conducted using Item Response Theory (IRT). We investigated associations of latent variable severity with objective indices of persistent physical disability, pulmonary and kidney dysfunction, and C-reactive protein and D-dimer blood levels, measured at the same follow-up assessment.
Results
The EFA extracted one factor, explaining 64.8% of variance; loadings were positive for all symptoms, and above 0.35 for 16 of them. The latent trait generated using IRT placed fatigue, psychiatric, and cognitive manifestations as the most discriminative symptoms (coefficients > 1.5, p < 0.001). Latent trait severity was associated with decreased body weight and poorer physical performance (coefficients > 0.240; p ⩽ 0.003), and elevated blood levels of C-reactive protein (coefficient = 0.378; 95% CI 0.215–0.541; p < 0.001) and D-dimer (coefficient = 0.412; 95% CI 0.123–0.702; p = 0.005). Results were similar after excluding subjects with pro-inflammatory comorbidities.
Conclusions
Different symptoms that persist for several months after moderate or severe COVID-19 may unite within one latent trait of PASC. This trait is dominated by fatigue and psychiatric symptoms, and is associated with objective signs of physical disability and persistent systemic inflammation.
Nebular Heii emission implies the presence of energetic photons (E≽54 eV). Despite the great deal of effort dedicated to understanding Heii ionization, its origin has remained mysterious, particularly in metal-deficient star-forming galaxies. Unfolding Heii-emitting, metal-poor starbursts at z∼0 can yield insight into the powerful ionization processes occurring in the primordial universe. Here we present a study on the origin of the extended nebular Heii emission in SBS 0335-052E, one of the most metal-poor (Z ∼ 3% Z⊙ Heii-emitter starbursts known locally. Based on optical VLT/MUSE spectroscopic and Chandra X-ray observations, and current stellar models we found that the Heii-ionization budget of SBS 0335-052E can only be produced by peculiar, nearly metal-free ionizing stars (called here “PopIII-like” stars) with a top-heavy initial mass function. This result is in line with recent simulations for PopIII star formation down to z=0.
The Dimensional Anhedonia Rating Scale (DARS) is a novel questionnaire to assess anhedonia of recent validation. In this work, we aim to study the equivalence between the traditional paper-and-pencil and the digital format of DARS. Sixty-nine patients filled the DARS in a paper-based and digital versions. We assessed differences between formats (Wilcoxon test), validity of the scales [Kappa and intraclass correlation coefficients (ICCs)], and reliability (Cronbach’s alpha and Guttman’s coefficient). We calculated the comparative fit index and the root mean squared error (RMSE) associated with the proposed one-factor structure. Total scores were higher for paper-based format. Significant differences between both formats were found for three items. The weighted Kappa coefficient was approximately 0.40 for most of the items. Internal consistency was greater than 0.94, and the ICC for the digital version was 0.95 and 0.94 for the paper-and-pencil version (F = 16.7, p < 0.001). Comparative Adjustment Index was 0.97 for the digital DARS and 0.97 for the paper-and-pencil DARS, and RMSE was 0.11 for the digital DARS and 0.10 for the paper-and-pencil DARS. We concluded that the digital DARS is consistent in many respects with the paper-and-pencil questionnaire, but equivalence with this format cannot be assumed without caution.
Conceptualising Schneider’s first-rank symptoms (FRS) as a diagnostic test whose performance can be measured in terms of sensitivity and specificity involves some issues that require reflection. The first formal proposal was contained in a 1939 monograph Schneider wrote, but little is known of their prehistory. In recent years there has been renewed interest in their clinical value.
Objectives
This work aims to review the the diagnostic the evolution and diagnostic accuracy of FRS.
Methods
A non-systematic review was performed, searching Pubmed/MEDLINE for articles using the keywords “schizophrenia” and “first rank symptoms”.
Results
From the beginning of Western descriptive psychopathology in the early 19th century, symptoms have been observed later described as first-rank by Schneider. When FRS are conceived as simple clinical indicators at a low level of inference, the results of the meta-analytic estimate of their diagnostic accuracy can be considered as a valid appraisal of their performance and usefulness. However, when FRS are conceptualised from a psychopathological perspective as strange and incomprehensible experiences that cannot be reduced merely to their propositional content and require substantial expertise and skill to be properly evaluated, the meta-analytic estimates can hardly be seen as a valid evaluation of their diagnostic significance, considering that some FRS are extremely difficult to assess properly.
Conclusions
The descriptions of these symptoms present substantial temporal and geographical continuity, over two centuries and in many countries. There is contradictory information concerning the validity of FRS as a clinical indicator. Phenomenologically informed studies are needed to address this research gap.
Pork is one of the most consumed meats worldwide, yet, pork quality remains an issue for the industry, mainly because of flavour, colour and water holding capacity instabilities. Castration techniques combined with dietary supplementation with ractopamine hydrochloride (RAC) seem to be a tangible solution to deal with these issues. There is a lack of knowledge of how these techniques will impact the proteomic profile and, consequently, the meat quality. The main goal of this work was to study the proteomic profile of non-aged pork meat under different sexual conditions and RAC dietary supplementation, and how the combination of these two factors impacts meat quality attributes. Forty-eight animals were distributed in six treatments, three sexual conditions (females; surgically castrated males; immune castrated males) and two diets (with RAC inclusion or without). For proteomic analysis, a sample of the Longissimus dorsi muscle was collected 24 h after slaughter and analysed using one-dimensional SDS/PAGE. The ultimate pH and colour (L*, a*, b*) were measured in the carcasses after 24 h, then meat samples were collected to measure drip, cooking and thawing losses, as well as the shear force. The interaction between gender and diet affected the ultimate pH and the L* parameter. Meat tenderness was only influenced by diet. Twenty-seven protein bands were revealed by SDS/PAGE, six of them with the protein abundance affected by diet. In conclusion, the inclusion of dietary RAC caused differences in the pork meat proteome, and more studies are necessary to fully explore the proteins involved in these changes.
The COVID-19 pandemic is a global challenge for humanity, in which a large number of resources are invested to develop effective vaccines and treatments. At the same time, governments try to manage the spread of the disease while alleviating the strong impact derived from the slowdown in economic activity. Governments were forced to impose strict lockdown measures to tackle the pandemic. This significantly changed people’s mobility and habits, subsequently impacting the economy. In this context, the availability of tools to effectively monitor and quantify mobility was key for public institutions to decide which policies to implement and for how long. Telefonica has promoted different initiatives to offer governments mobility insights throughout many of the countries where it operates in Europe and Latin America. Mobility indicators with high spatial granularity and frequency of updates were successfully deployed in different formats. However, Telefonica faced many challenges (not only technical) to put these tools into service in a short timing: from reducing latency in insights to ensuring the security and privacy of information. In this article, we provide details on how Telefonica engaged with governments and other stakeholders in different countries as a response to the pandemic. We also cover the challenges faced and the shared learnings from Telefonica’s experience in those countries.
