Giant left atrium is extremely rare in the paediatric population, especially in asymptomatic cases. We report a 5-year-old child with a giant left atrium due to “non-rheumatic” mitral valve regurgitation that presented as a stroke secondary to atrial tachycardia. This case is noteworthy for the unusual “silent” manifestation of a giant left atrium.
This review article points to a number of ways in which the study of political participation has followed separate tracks, hence preventing it from deploying its full potential. We argue that the field stands to benefit much from ‘bridging’ different approaches and insights, combining those from different disciplines or subdisciplines. We review works that try to build such bridges, with the aim of encouraging dialogue across the disciplinary boundaries between political science and political sociology, on the one hand, and sociology and social movement studies, on the other. We advocate that students of political participation take such ‘bridges’ seriously in their work and employ them as the basis for new dynamic theorization. We suggest five possible ways in which the study of political participation may combine different perspectives and research traditions. Three of them are theoretical: bridging rationalist, structuralist and culturalist theoretical approaches; bringing together cognitive (attitudes) and affective (emotions) explanations; and combining macro- and micro-level accounts. The fourth is methodological: bridging qualitative and quantitative methodological approaches. The fifth is substantive: bridging a focus on electoral (institutional) participation with one on non-electoral (non-institutional) participation.
The concept of total suffering is widely recognized in palliative care (PC), encompassing a range of interconnected and complex factors that collectively shape the evolving and individualized experience of a patient’s illness journey. Studies on will to live (WtL) in terminally ill patients have demonstrated its variability over time and various factors that influence these changes.
Methods
To objectively investigate the concept of total suffering and WtL; including their fluctuation over time and associations with sociodemographic, clinical, physical, and psychological symptoms in a sample of individuals with life-limiting conditions receiving PC. This multicenter Iberian study involved 3 centers in Portugal and 1 in Spain. A total of 107 individuals with life-limiting conditions consented to participate. To capture the dynamic and multifaceted components of total suffering, we had each participant completed the Edmonton Symptom Assessment Scale (ESAS) along an additional WtL visual analogue once daily over a 30-day period.
Results
WtL demonstrated various patterns over time. While some patterns reflected relative stability, other demonstrated substantive fluctuation during the course of illness. Significant correlations were observed between WtL and all other ESAS items. Moderate positive correlations were found between WtL and total ESAS score and its physical and psychological sub-scores. Spearman’s correlation coefficients between all physical and psychosocial items on the ESAS were statistically significant across all 45 correlations performed, with only 5 showing moderate strength; the remaining correlations were weaker.
Significance of results
Evidence-based understanding of WtL is critical to improving care for patients who experience suffering toward end-of-life and their families. Further research is needed to inform and refine interventions targeting total suffering.
The central questions addressed in this Element are: How has protest politics changed over time, especially but not exclusively in the most recent times. And what are the implications and consequences of these transformations? In this vein, the Element identifies a number of processes of change as outlined in the literature, going from the expansion of the repertoires of contention to the normalization of protest and of the protesters, and the shifting scale of contention to more individual-level processes such as the individualization and digitalization of protest. The Element's aim is to provide a critical discussion of scholarship on the transformation of protest politics and social movement activism.
To analyse the evolution of the vertigo index and its relationship with perceived disability in unilateral and bilateral Ménière’s disease, assessing differences based on disease progression and clinical subtypes.
Methods
A longitudinal descriptive study was conducted on unilateral and bilateral Ménière’s disease patients, with data collected between 1977 and 2023 from two referral centres. Clinical and functional data were retrospectively reviewed to ensure compliance with updated diagnostic criteria. The vertigo index, integrating episode duration and frequency, quantified vertigo burden. Functional impact was assessed using the six-item American Academy of Otolaryngology Head and Neck Surgery disability scale, categorising patients into mild or moderate/severe disability groups.
Results
Bilateral Ménière’s disease patients had a higher proportion of moderate/severe episodes (31.4 per cent) than unilateral Ménière’s disease patients (11 per cent). In unilateral Ménière’s disease patients, disability perception increased after 20 years of disease evolution. The vertigo index declined over time, except in later stages, where episodes were more disabling.
Conclusion
These findings underscore the need for long-term follow up, particularly in bilateral Ménière’s disease, where greater disability was observed. Disease management should adapt over time, addressing both vertigo burden and psycho-affective consequences.
In water distribution networks (WDNs), pressure limitation represents an effective strategy to reduce water losses. This goal can be achieved by means of pressure reducing valves (PRVs), which dissipate exceeding hydraulic energy. For more sustainable management of water systems within a circular economy framework, PRVs can be replaced with energy-producing devices, such as pumps as turbines (PATs). This study presents a general approach for the selection of the optimal PAT to install in a given WDN. The approach assesses the techno-economic feasibility of a fleet of turbomachines by evaluating the rate of energy recovery, the levelized cost of electricity and the payback period of each PAT. Two PAT regulation strategies are accounted for, namely hydraulic and electrical regulations. The approach is applied to a real-world case study consisting of a WDN in Northern Italy that supplies approximately 5,000 users. In addition, a fleet of 16 turbomachines is considered, of which the experimental characteristic curves are available in both pump and turbine modes. The analyses carried out in this article allow selecting the optimal PAT to install within the considered WDN, which recovers 44.1 % of the hydraulic energy of the network with a maximum investment cost of € 24,500.
The Indo-West Pacific region serves as the primary habitat for the majority of extant hexapodid crabs. The hexapodids boast a rich evolutionary history dating back to the Cretaceous, marked by a significant radiation throughout the Cenozoic, while the Paleocene–Miocene of tropical America emerges as a pivotal center of radiation, evidenced by reported hexapodid species in Barbados, Panama, Peru, Trinidad, and Venezuela. Through an examination of the paleocarcinological collection at the Museu Paraense Emílio Goeldi, a new genus and species within Hexapodidae is described and illustrated. Rodneyellus feldmanni, the newly described taxon, is named in honor to Dr. Rodney Feldmann for his unwavering commitment to fossil crustacean research. This report marks the inaugural documentation of Hexapodidae in Brazil, encompassing both fossilized and extant representatives. Furthermore, the Pirabas Formation emerges as a critical locus for comprehending the contemporary distribution of decapod crustaceans across tropical America.
Objectives/Goals: Unhealthy lifestyle habits may increase medical students’ risk for metabolic dysfunction-associated fatty liver disease (MAFLD) and non-alcoholic fatty pancreatic disease (NAFPD). This study aims to investigate how these lifestyle factors affect liver and pancreas health in preclinical medical students using diagnostic ultrasound imaging. Methods/Study Population: Using diagnostic ultrasound imaging, we propose a research study to evaluate the anatomical changes of the liver and pancreas associated with lifestyle among medical students in UCC. Forty-two (42) medical students from the Central University of the Caribbean who are in their preclinical years will be recruited to perform an abdominal ultrasound. To measure the diameter of the right liver lobe, we will employ the craniocaudal measurement method established by Riestra. et al. (2018). The parameter established by Rumack et al. (2011) will be utilized to assess liver texture and categories by Lee JS et al. (2009) to pancreas fat infiltration grades. Results/Anticipated Results: This study expects to reveal a significant correlation between the lifestyles of preclinical medical students and the health of their liver and pancreas, particularly in size and texture. We anticipate identifying specific lifestyle factors – such as dietary habits and physical activity levels – that contribute to the prevalence of hepatic and pancreatic steatosis. Additionally, we expect to highlight the need for targeted interventions to promote healthier lifestyles among medical students to mitigate risks associated with MAFLD and NAFPD. Discussion/Significance of Impact: This study is significant for monitoring changes in liver and pancreas health, preventing complications, and improving health quality while reducing future costs. It may guide the creation of tailored wellness programs for medical students, enhancing their well-being and contributing to better healthcare practices and educational strategies.
By constraining organic carbon (OC) turnover times and ages, radiocarbon (14C) analysis has become a crucial tool to study the global carbon cycle. However, commonly used “bulk” measurements yield average turnover times, masking age variability within complex OC mixtures. One method to unravel intra-sample age distributions is ramped oxidation, in which OC is oxidized with the aid of oxygen at increasing temperatures. The resulting CO2 is collected over prescribed temperature ranges (thermal fractions) and analyzed for 14C content by accelerator mass spectrometry (AMS). However, all ramped oxidation instruments developed to date are operated in an “offline” configuration and require several manual preparation steps, hindering sample throughput and reproducibility. Here we describe a compact, online ramped oxidation (ORO) setup, where CO2 fractions are directly collected and transferred for 14C content measurement using an AMS equipped with a gas ion source. Our setup comprises two modules: (i) an ORO unit containing two sequential furnaces, the first of which holds the sample and is ramped from room temperature to ∼900°C, the second of which is maintained at 900°C and holds catalysts (copper oxide and silver) to ensure complete oxidation of evolved products to CO2; and (ii) a dual-trap interface (DTI) collection unit containing two parallel molecular sieve traps, which alternately collect CO2 from a given fraction and handle its direct injection into the AMS. Initial results for well-characterized samples indicate that 14C content uncertainties and blank background values are like those obtained during routine gas measurements at ETH, demonstrating the utility of the ORO-DTI setup.
Amongst the various strategies studied to reduce polluting agents in water, both from anthropogenic and natural sources, adsorption processes are among the most widespread techniques. Layered double hydroxides (LDH, anionic adsorbers) play a fundamental role in the treatment of industrial wastewater, which often contains both anionic and cationic species. The objectives of the present study were to synthesize a (Mg, Zn)Al-NO3 LDH, and a composite between the LDH and montmorillonite (Mnt, cationic exchanger), and to test their adsorption capacity for both cationic and anionic pollutants in two different samples of industrial wastewater. The compounds were characterized by means of inductively coupled plasma-atomic emission spectroscopy (ICP-AES), X-ray powder diffraction (XRPD), Fourier-transform infrared (FT-IR) spectroscopy, differential thermal analysis/thermogravimetry (DTA-TG), and transmission electron microscopy (TEM). Results of product yields and extraction performance provided evidence that the synthesized compounds were active in the removal of various kinds of pollutants from real wastewaters. The adsorption capacity, in the case of the removal of cations varied from ~85 to 100% and from ~92 to 100% when the LDH and the LDH-Mnt, respectively, were used. The 56–100% removal of anions was instead obtained for both the adsorbents.
Increasing global digitalization is changing the everyday language skills required to participate in society, to carry out professional activities, and to take advantage of educational opportunities. As a result, new linguistic and digital competences are required for migrants. At the same time, digitalization offers new potential for learner-oriented language learning. In this article, we compare the results of two studies on teachers of adult multilingual migrant learners. These teachers instruct learners at different levels of literacy and with varied prior formal learning experiences. Both studies are situated in the German education system. The results illustrate how teachers and learners can work together using digital technologies to promote language learning. We explore the opportunities for effective, multilingual, and motivating language learning, as well as the challenges faced by learners and teachers, pointing to the need for further training in digital technology for both groups.
The revival of psilocybin in psychopharmacological research heralds a potential paradigm shift for treating mood and anxiety disorders, and other psychiatric conditions beyond the psychotic spectrum. This critical review evaluates current evidence on psilocybin’s efficacy, juxtaposing potential benefits with the practical aspects of psychedelic-assisted psychotherapy (PAP) and the methodological constraints of existing research.
An electronic literature search was conducted using PubMed/MEDLINE, selecting studies published up to December 2023 that explored the clinical use of psilocybin in mood and anxiety disorders, obsessive-compulsive disorder, post-traumatic stress disorder, and substance use disorder. Despite promising preliminary results suggesting psilocybin’s efficacy in alleviating depression and anxiety, as well as obsessions, compulsions, and addictive behaviors, significant evidence gaps persist. These include evaluating the efficacy of psilocybin compared to standard antidepressants or anxiolytic molecules and identifying patient subpopulations that might benefit most from PAP. Concerns about psilocybin’s safety, long-term efficacy, and optimal dosage remain unclear due to previous trials’ limitations. Real-world implementation faces challenges, including infrastructural requirements, personnel training, and unresolved legal and ethical issues. This paper argues for further research to substantiate the evidence base, emphasizing the need for larger studies that overcome current methodological limitations and explore psilocybin’s full therapeutic potential. While psilocybin holds promise for psychiatry, its successful translation from research to clinical practice demands more robust evidence on efficacy, safety, and methodological rigor. In addition, other factors, such as cultural stigma and legal/ethical issues, need to be successfully addressed to facilitate psilocybin’s implementation in healthcare systems.
West Nile virus (WNV) is a mosquito-borne pathogen that can infect humans, equids, and many bird species, posing a threat to their health. It consists of eight lineages, with Lineage 1 (L1) and Lineage 2 (L2) being the most prevalent and pathogenic. Italy is one of the hardest-hit European nations, with 330 neurological cases and 37 fatalities in humans in the 2021–2022 season, in which the L1 re-emerged after several years of low circulation. We assembled a database comprising all publicly available WNV genomes, along with 31 new Italian strains of WNV L1 sequenced in this study, to trace their evolutionary history using phylodynamics and phylogeography. Our analysis suggests that WNV L1 may have initially entered Italy from Northern Africa around 1985 and indicates a connection between European and Western Mediterranean countries, with two distinct strains circulating within Italy. Furthermore, we identified new genetic mutations that are typical of the Italian strains and that can be tested in future studies to assess their pathogenicity. Our research clarifies the dynamics of WNV L1 in Italy, provides a comprehensive dataset of genome sequences for future reference, and underscores the critical need for continuous and coordinated surveillance efforts between Europe and Africa.
Introduction: Recurrent major depressive disorder (MDD) has been associated with cognitive impairment and hippocampus atrophy. Additionally, in older adults it is related to increased dementia risk, as well as being dementia’s prodromal syndrome.
Case Report: A 68-year-old female patient, with a history of MDD beginning in 2014, has been under the care of the Psychogeriatrics service at HC-UFMG. In 2015, she was 60-year-old and underwent her first MRI scan. At that time, the Medial Temporal Atrophy Score (MTA) was 2 and she had a treatment resistant depression (TRD). She began multimodal treatments, including ECT, achieving only partial remission. Since then, the patient had recurrences of depression without the remission of cognitive impairment. In 2021, her MTA Score was still 2 with TDR symptoms. Currently, she is on Venlafaxine 150mg, Mirtazapine 30mg, Lithium 300mg, Olanzapine 5mg, Clonazepam 0.25mg and maintenance ECT every 45 days. The patient remains with cognitive impairment that leads to disabilities but had not significantly progressed. On the other hand, the main impact in functionality is related to depressive symptoms, especially to the loss of interest and apathy.
Discussion: This case stands out due to the combination of hippocampal atrophy at a relatively young age and severe depression with cognitive impairment that has not progressed to dementia in 9 years. Severe depression can lead to significant cognitive deficits, as well as, hippocampus atrophy. While depression is related to hippocampus atrophy, it has not been related to TRD in a review study with Voxel-Based Morphometry. Conversely, Alzheimer’s Disease is related to MTA ≥2 scores, as well as depressive symptoms. MTA 2 in a person of 60 years of age is not considered normal. When combined with cognitive impairment, these findings are generally related to neurodegeneration. Since both MTA and cognitive deficits were relatively stable, the hypothesis of a cognitive impairment and hippocampus atrophy due to depression were more likely.
Conclusions: MDD leads to cognitive impairment in older adults, as well as hippocampus atrophy. Nevertheless, depression and age are important risk factors for dementia and, therefore, a progression to dementia due to a neurodegenerative disease is still possible.
Background: The Cognitive Domains and Functional Assessment Questionnaire (CDFAQ) assess cognitive and functional decline based on the DSM-5 criteria for Neurocognitive Disorders. Its accuracy has been assessed and was translated and validated into English. The informant version (CDFAQ-IV) is a 30-item questionnaire that assesses six cognitive domains with 5 items each: Complex Attention (CA), Executive Functions (EF), Learning and
Memory (LM), Language (L), Perceptual-Motor (PM) and Social Cognition. The development of CDFAQ-IV was based on theDSM-5 cognitive domains, but its factor analysis has not been done yet.
Objectives: To perform a Confirmatory Factor Analysis of the CDFAQ-IV to assess the six-factor cognitive domain model.
Methods: Older adults and their informants were invited to participate in this study. The CDFAQ-IV was applied in 292 older adults’ informants. We used the JASP for a Confirmatory Factor Analysis based on Lavaan R Packages. The confirmatory factor analysis was chosen to manual six-factor model. This study was approved by the ethics committee of UFMG.
Results: Concerning model fitness in the confirmatory factor analysis the X2 was significant (p < .001), standardized root mean square residual (SRMR) was .059 (accepted < .08) and the goodness of fit index (GFI) .984 (accepted > .9). However, the root mean square error of approximation (RMSEA) was marginal to the accepted fitness .066 (accepted < .06) and the comparative fit index CFI was .839 under the accepted cutoff (accepted > .9).
Conclusions: The six-factor model of the showed a good fit for three parameters, marginal for one and negative for the CFI. These results point to a convergence of the questionnaire and factors the DSM-5 cognitive domains. These are still preliminary results and we aim to increase our sample to further assess the confirmatory factor analysis.
Introduction: Throughout the course of the dementia, patients generally need a guardian to protect their rights due to the severity of their mental disabilities. The laws and procedures for guardianship for people with disabilities have been updated in several countries based on the UN Convention on the Rights of Persons with Disabilities promulgated in 2006.
Objectives: To compare the law and procedures for guardianship for people with mental disabilities of twelve countries from six continents.
Methods: Narrative review searching for civil codes/guardianship procedures, date of promulgation, scope of the guardian authority, preferred guardian, duration of the guardianship.
Results: Most countries predominantly promulgated their laws after the year 2000, being half of them updated after 2006. Most countries have two types of guardianship scopes: one concerning financial affairs and the other concerning personal affairs (such as welfare and medical care). Generally, guardianship concerning financial matters is the first to be established. In addition, most countries maintain the ward’s right to vote. In five out of twelve countries, there is an order of preference for choosing the guardian, being the spouses and adult children the preferred guardians. All these countries have the possibility of temporary guardianship. Three countries have a maximum period for guardianship with the possibility of renewal, while all others have indefinite time for guardianship duration. Only France explicitly grants the right to the ward to make medical decisions within guardianship procedures. Brazil’s Civil Code restricts guardianship to financial matters, whereas the Civil Procedure Code requires judges to define the scope of guardianship’s authority for each of the activities of the civil life. Since both codes hold equal authority, judges typically determine the extent of guardianship on a case- by-case basis.
Conclusions: Half of the nations have updated their laws after the promulgation of the UN Convention on the Rights of Persons with Disabilities.
Dementia is expected to increase worldwide and further Discussion concerning the rights of people with dementia is still needed. Although there is no ideal legal framework, the comparison of procedures from different countries may lead to valuable insights for further Discussions andassessments.
Unveiling the pressure‒temperature path of low-grade metamorphic rocks is challenging because of the occurrence of detrital minerals and high-variance mineral assemblages (i.e. chlorite–white mica–quartz). This paper is an attempt to reconstruct the pressure–temperature history on metapelites from a low-grade metamorphic unit, i.e. the Cabanaira Unit, located in the Marguareis Massif (Western Ligurian Alps, Italy). In order to obtain the most robust result possible, multi-equilibrium thermobarometry, forward modelling and crystallochemical index measurements are used together to reconstruct a pressure–temperature path, with consideration of the strengths and weaknesses of these methods.
This multidisciplinary approach allowed us to reconstruct the metamorphic evolution of the unit of interest, characterised by a pressure peak reached under low-temperature conditions (0.85–0.68 GPa and 250–285°C) followed by decompressional warming (low pressure–high temperature, 0.4-0.6 GPa and 300–335°C).
This pressure‒temperature path is consistent with the tectonic evolution of the investigated area proposed by previous studies, where a geological scenario in which the Cabanaira Unit experienced subduction-related processes was postulated, even if the reasons for warming remain unclear.
Multi-equilibrium thermobarometry is considered to be the most suitable method to unravel the metamorphic history of low-grade rocks, whereas forward thermodynamic modelling and the calculation of crystallochemical indexes seem to resolve only some segments of the pressure‒temperature path.
Dioctophyme renale, the giant kidney worm, is a nematode related to Trichuris sp and is distributed worldwide. These parasites locate in the kidney of their definitive hosts (mainly belonging to the order Carnivora) and have an indirect life cycle with an annelid as the main intermediate host. Humans are rarely affected, but in those that are, 1 or both kidneys are destroyed. In South America, D. renale is widespread in riparian regions where changing climatic conditions, environmental degradation, and compromised sanitation are increasing the risk of distribution of this parasite, including humans. Here, we provide the descriptions of the genetic diversity of the parasite in the region by analysing 73 adult D. renale samples collected from domestic and wild carnivores. The most common hosts were (Canis lupus familiaris) and maned wolf (Chrysocyon brachyurus Fam. Canidae) among domestic and wild carnivores, respectively. This work shows the descriptions of the genetic diversity of this parasite complementing molecular methods and classical and probabilistic phylogeography. Our results strongly suggest that this parasite has been present on the continent long enough to develop local genetic variants. Also, the phylogenies show transmission between localities and bidirectional transmission between domestic and wild species. We now have new tools to understand the ecological dynamics of this parasite such as molecular markers to study its genetic diversity as well as for identification and reporting in cryptic cases.
The research reconstructs and analyses the role played by livestock associations in Italy during the 20th century. The article initially focuses on local associative experiences before World War II and subsequently on national associations, whose formation also depended on the goal of promoting the application of technical innovations. Their impact, specifically that of artificial insemination and semen freezing, has indeed influenced the production process in the livestock sector since the 1940s with genetic changes in animals for productivity purposes. Focusing on specific case studies (mainly Associazione Italiana Allevatori, but also ANAFI, ANARB, and ANABIC), the paper analyses the motivations behind the establishment of the associations, the relationships with members and public institutions, and finally, support strategies for breeders.
