Intersubjectivity in media consumption as a result of the relation between text and context: the case of Game of Thrones
Television has been changing for a number of years due to the growing proliferation of platforms and interconnection of multiple media forms. These changes have reshaped the relation between the idea of text(s) (i.e., TV series) and context(s) (i.e., fan practices) in the process of media consumption. This paper aims to clarify how, in the case of the TV series Game of Thrones and with reference to an empirical research carried out by the authors, the interlacement of textual and contextual elements can determine different forms of experience and different levels of intersubjectivity in fansâ practices.Depuis un certain nombre d'annĂ©es, la tĂ©lĂ©vision a Ă©tĂ© modifiĂ©e par la prolifĂ©ration croissante des plates-formes et de l'interconnection de multiples formes de mĂ©dias. Par rapport au processus de consommation des medias, ces changements ont remodelĂ© la relation entre les concepts de texte/s (i.e., series tĂ©lĂ©visĂ©es) et de contexte/s (i.e., les pratiques des fans). Cet article vise Ă clarifier comment, dans le cas de la sĂ©rie tĂ©lĂ©visĂ©Â Game of Thrones et en rĂ©fĂ©rence Ă une recherche empirique menĂ©e par les auteurs, l'entrelacement des Ă©lĂ©ments textuels et contextuels peut determiner diffĂ©rentes formes d'expĂ©rience et diffĂ©rents niveaux d'intersubjectivitĂ© dans les pratiques des fans
Italian Wikipedia and epilepsy: an infodemiological study of online information-seeking behavior
Wikipedia is the most commonly accessed source of health information by both healthcare professionals and the lay public worldwide. We aimed to evaluate information-seeking behavior of Internet users searching the Italian Wikipedia for articles related to epilepsy and its treatment. Using Pageviews Analysis, we assessed the total and mean monthly views of articles from the Italian Wikipedia devoted to epilepsy, epileptic syndromes, seizure type, and antiepileptic drugs (AEDs) from January 1, 2015 to October 31, 2017. We compared the views of the article on epilepsy with those of articles focusing on Alzheimer's disease, migraine, multiple sclerosis, syncope, and stroke and adjusted all results for crude disease prevalence. With the only exception of the article on multiple sclerosis, the adjusted views for the Italian Wikipedia article on epilepsy were higher than those for the other neurological disorders. The most viewed articles on seizure type were devoted to tonic-clonic seizure, typical absence seizure, tonic convulsive seizures, and clonic convulsive seizures. The most frequently accessed articles on epilepsy syndromes were about temporal lobe epilepsy and Lennox-Gastaut syndrome. The most frequently viewed articles on AEDs were devoted to valproic acid, carbamazepine, and levetiracetam. Wikipedia searches seem to mirror patients' fears and worries about epilepsy more than its actual epidemiology. The ultimate reasons for searching online remain unknown. Epileptologists and epilepsy scientific societies should make greater efforts to work jointly with Wikipedia to convey more accurate and up-to-date information about epilepsy
Report of 4 Cases and Review of the Literature
We reviewed the clinical, microbiologic, and outcome characteristics of 72 patients with human immunodeficiency virus (HIV)-associated histoplasmosis (4 newly described) reported in Europe over 20 years (1984-2004). Seven cases (9.7%) were acquired in Europe (autochthonous), whereas the majority involved a history of travel or arrival from endemic areas. The diagnosis of progressive disseminated histoplasmosis (PDH) was made during life in 63 patients (87.5%) and was the acquired immunodeficiency syndrome (AIDS)-presenting illness in 44 (61.1%). Disease was widespread in 66 patients (91.7%) and localized in 6 (8.3%), with the skin being the most frequent site of localized infection. Overall skin involvement was reported in 47.2% of the patients regardless of whether histoplasmosis was acquired in Africa or South America. Reticulonodular or diffuse interstial infiltrates occurred in 52.8%. The diagnosis was made during life by histopathology plus culture in 44 patients (69.8%), histopathology alone in 18 (28.5%), and culture alone in 1 (1.5%). During the induction phase amphotericin B and itraconazole (74.6%) were the single most frequently used drugs. Both drugs were also used either in combination (10.2%) or in sequential therapy (11.8%). Cumulative mortality rate during the induction phase of treatment was 15.2%. Overall, 37 patients died (57.8%); death occurred early in the course in 18 (28.1%). Seven of 40 patients (17.5%) who responded to therapy subsequently relapsed. Autopsy data in 13 patients confirmed the widespread disseminated nature of histoplasmosis (85%) among AIDS patients with a median of 4.5 organs involved. The results of the present report highlight the need to consider the diagnosis of PDH among patients with AIDS in Europe presenting with a febrile illness who have traveled to or who originated from an endemic area
+874(TâA) single nucleotide gene polymorphism does not represent a risk factor for Alzheimer's disease
In the recent years, several cytokines have been associated with Alzheimer's disease (AD) development and progression and many studies have correlated this risk with polymorphisms in the genes encoding these molecules. Also the type 1 cytokine interferon (IFN)-Îł belongs to a cytokine class that affects the immune function; in fact it plays a major role in defence against viruses and intracellular pathogens but also in the induction of the immune-mediated inflammatory response. The aim of this study was to evaluate the role of IFN-Îł in AD by studying the association of +874TâA IFN-Îł gene polymorphism with AD. We included in this study 115 AD patients (70 women, 45 men, mean age 80) and 90 sex and age-matched healthy controls (HC, 51 women, 39 men, mean age 82) from northern Italy. Genomic DNA was extracted with the salting-out method from whole blood of all subjects; the genotyping at IFN-Îł loci was assessed with ARMS-PCR. The data obtained from the +874TâA IFN-Îł gene polymorphism analysis of AD patients and HC lack of any statistically significant differences also when stratified according to gender. In conclusion these results confirm the previous shown lack of association between +874TâA IFN-Îł gene polymorphism and the risk of AD. However, other polymorphisms have been demonstrated to influence IFN-Îł transcription and since natural killer cells of AD patients show higher production of the cytokine, further analysis will be necessary to clarify the role of this gene in the pathogenesis of the disease
Editorial: Discourse, conversation and argumentation: Theoretical perspectives and innovative empirical studies, volume II
Research on discourse, conversation, and argumentation is conducted in several separate research communities that are spread across disciplines and have only limited intertwinement. This second volume of the Research Topic âDiscourse, Conversation and Argumentation: Theoretical Perspectives and Innovative Empirical Studiesâ intends to offer a comprehensive dialogical platform to explore further novel and promising theoretical perspectives to study discursive, conversational, and argumentative interactions from a psychological perspective. In addition, it provides an extensive stand of the latest innovative research investigating discursive, conversational, and argumentative interactions between individuals, groups, and institutions to shed light on the most recent methodological developments in examining these types of interactions
Editorial: Discourse, Conversation and Argumentation: Theoretical Perspectives and Innovative Empirical StudiesâVolume I
Thinking about how we participate in an interaction through verbal and non-verbal exchanges is a way to focus on explicit and implicit norms, personal and collective preferences, subjective and interpersonal theories, and social processes of construction of meaning that characterize our everyday communicative interactions. Although discursive, conversational, and argumentative interactions play an essential role in our lives, there is no integrated area of psychological research on these types of communicative interactions. A wide variety of works is available concerning the focus on the different roles played by social actors within the interactions (symmetric-asymmetric, protagonist-antagonist, and teacher-learner), as well as the interest for the constitutive (emotional, motivational, and cognitive) aspects of the interactions or developmental factors (skills, competences, and knowledge). However, research on these topics is conducted in a number of separate research communities that are spread across disciplines and have only limited intertwinements. This Research Topic intends to offer a dialogical platform for sharing studies on discourse, conversation, and argumentation from a psychological perspective. Different strands were bridged together to reach two main goals:
(1) to explore novel and promising theoretical perspectives to study discursive, conversational, and argumentative interactions from a psychological perspective;
(2) and provide an extensive platform of the latest innovative research investigating interactions between individuals, groups, and institutions.
The Research Topic provided an opportunity for researchers working in different international and psychological contexts to draw together their work within a common forum. Through their contributions, authors provided state-of-the-art of collective evidences in psychological research on discourse, conversation, and argumentation. They were able to place emphasis on opportunities for mutual awareness and integration by proposing a series of high-quality original research papers, reviews, and conceptual analyses on topics dealing with the above-mentioned issues. The contributions are focused on psychological perspectives on interactions and empirically supported approaches to analyze them. This panel of respectful researchers contributed to render the Research Topic particularly timely and open to colleagues who are continually exposed to nearly limitless sectorial approaches. In this vein, we hope that the contributions can be challenging for a large scientific audience to support integrated psychological research on discursive, conversational, and argumentative interactions
SQSTM1 mutations in frontotemporal lobar degeneration and amyotrophic lateral sclerosis
Objective: There is increasing evidence that common genetic risk factors underlie frontotemporal lobar degeneration (FTLD) and amyotrophic lateral sclerosis (ALS). Recently, mutations in the sequestosome 1 (SQSTM1) gene, which encodes p62 protein, have been reported in patients with ALS. P62 is a multifunctional adapter protein mainly involved in selective autophagy, oxidative stress response, and cell signaling pathways. The purpose of our study was to evaluate the frequency of SQSTM1 mutations in a dataset of unrelated patients with FTLD or ALS, in comparison with healthy controls and patients with Paget disease of bone (PDB). Methods: Promoter region and all exons of SQSTM1 were sequenced in a large group of subjects, including patients with FTLD or ALS, healthy controls, and patients with PDB. The clinical characteristics of patients with FTLD or ALS with gene mutations were examined. Results: We identified 6 missense mutations in the coding region of SQSTM1 in patients with either FTLD or ALS, none of which were found in healthy controls or patients with PDB. In silico analysis suggested a pathogenetic role for these mutations. Furthermore, 7 novel noncoding SQSTM1 variants were found in patients with FTLD and patients with ALS, including 4 variations in the promoter region. Conclusions: SQSTM1 mutations are present in patients with FTLD and patients with ALS. Additional studies are warranted in order to better investigate the role of p62 in the pathogenesis of both FTLD and ALS
Bridging Minds: A Mixed Methodology to Assess Networked Flow
The main goal of this contribution is to present a methodological framework to study Networked Flow, a bio-psycho-social theory of collective
creativity applying it on creative processes occurring via a computer network.
First, we draw on the definition of Networked Flow to identify the key methodological requirements of this model. Next, we present the rationale of a mixed methodology, which aims at combining qualitative, quantitative and structural analysis of group dynamics to obtain a rich longitudinal dataset. We argue that this integrated strategy holds potential for describing the complex dynamics of creative collaboration, by linking the experiential features of collaborative experience (flow, social presence), with the structural features of collaboration dynamics (network indexes) and the collaboration outcome (the creative product). Finally, we report on our experience with using this methodology in blended collaboration settings (including both face-to-face and
virtual meetings), to identify open issues and provide future research directions
Risk of progression in chronic phase-chronic myeloid leukemia patients eligible for tyrosine kinase inhibitor discontinuation: Final analysis of the TFR-PRO study
Disease progression to accelerated/blast phase (AP/BP) in patients with chronic phase chronic myeloid leukemia (CP-CML) after treatment discontinuation (TD) has never been systematically reported in clinical trials. However, recent reports of several such cases has raised concern. To estimate the risk of AP/BP among TD-eligible patients, we conducted TFR-PRO, a cohort retro-prospective study: 870 CP-CML patients eligible for TD formed a discontinuation cohort (505 patients) and a reference one (365 patients). The primary objective was the time adjusted rate (TAR) of progression in relation to TD. Secondary endpoints included the TAR of molecular relapse, that is, loss of major molecular response (MMR). With a median follow up of 5.5âyears and 5188.2 person-years available, no events occurred in the TD cohort. One event of progression was registered 55âmonths after the end of TD, when the patient was contributing to the reference cohort. The TAR of progression was 0.019/100 person-years (95% CI [0.003-0.138]) in the overall group; 0.0 (95% CI [0-0.163]) in the discontinuation cohort; and 0.030 (95% CI [0.004-0.215]) in the reference cohort. These differences are not statistically significant. Molecular relapses occurred in 172/505 (34.1%) patients after TD, and in 64/365 (17.5%) patients in the reference cohort, pâ<â.0001. Similar rates were observed in TD patients in first, second or third line of treatment. CML progression in patients eligible for TD is rare and not related to TD. Fears about the risk of disease progression among patients attempting TD should be dissipated
Stratifying the Presymptomatic Phase of Genetic Frontotemporal Dementia by Serum NfL and pNfH: A Longitudinal Multicentre Study
Objective: Although the presymptomatic stages of frontotemporal dementia (FTD) provide a unique chance to delay or even prevent neurodegeneration by early intervention, they remain poorly defined. Leveraging a large multicenter cohort of genetic FTD mutation carriers, we provide a biomarker-based stratification and biomarker cascade of the likely most treatment-relevant stage within the presymptomatic phase: the conversion stage. Methods: We longitudinally assessed serum levels of neurofilament light (NfL) and phosphorylated neurofilament heavy (pNfH) in the Genetic FTD Initiative (GENFI) cohort (n = 444), using single-molecule array technique. Subjects comprised 91 symptomatic and 179 presymptomatic subjects with mutations in the FTD genes C9orf72, GRN, or MAPT, and 174 mutation-negative within-family controls. Results: In a biomarker cascade, NfL increase preceded the hypothetical clinical onset by 15 years and concurred with brain atrophy onset, whereas pNfH increase started close to clinical onset. The conversion stage was marked by increased NfL, but still normal pNfH levels, while both were increased at the symptomatic stage. Intra-individual change rates were increased for NfL at the conversion stage and for pNfH at the symptomatic stage, highlighting their respective potential as stage-dependent dynamic biomarkers within the biomarker cascade. Increased NfL levels and NfL change rates allowed identification of presymptomatic subjects converting to symptomatic disease and capture of proximity-to-onset. We estimate stage-dependent sample sizes for trials aiming to decrease neurofilament levels or change rates. Interpretation: Blood NfL and pNfH provide dynamic stage-dependent stratification and, potentially, treatment response biomarkers in presymptomatic FTD, allowing demarcation of the conversion stage. The proposed biomarker cascade might pave the way towards a biomarker-based precision medicine approach to genetic FTD. ANN NEUROL 2022;91:33â47
