Published: December 2023

BACKGROUND:

A high permanent pacemaker implantation (PPI) risk remains a concern of self-expandable transcatheter aortic valve implantation, despite the continued improvements in implantation methodology. We aimed to assess the impact of real-time direct visualization of the membranous septum using transjugular intracardiac echocardiography (ICE) during transcatheter aortic valve implantation on reducing the rates of conduction disturbances including the need for PPI.

METHODS:

Consecutive patients treated with Evolut R and Evolut PRO/PRO+ from February 2017 to September 2022 were included in this study. We compared outcomes between the conventional implantation method using the 3-cusps view (3 cusps without ICE group), the recent method using cusp-overlap view (cusp overlap without ICE group), and our novel method using ICE (cusp overlap with ICE group).

RESULTS:

Of the 446 patients eligible for analysis, 211 (47.3%) were categorized as the 3 cusps without ICE group, 129 (28.9%) were in the cusp overlap without ICE group, and 106 (23.8%) comprised the cusp overlap with ICE group. Compared with the 3 cusps without ICE group, the cusp overlap without ICE group had a smaller implantation depth (2.2 [interquartile range, 1.0–3.5] mm versus 4.3 [interquartile range, 3.3–5.4] mm;
P
<0.001) and lower 30-day PPI rates (7.0% versus 14.2%;
P
=0.035). Compared with the cusp overlap without ICE group, the cusp overlap with ICE group had lower 30-day PPI rates (0.9%;
P
=0.014), albeit with comparable implantation depths (1.9 [interquartile range, 0.9–2.9] mm;
P
=0.150). Multivariable analysis showed that our novel method using ICE with the cusp-overlap view was independently associated with a 30-day PPI rate reduction. There were no group differences in 30-day all-cause mortality (1.4% versus 1.6% versus 0%;
P
=0.608).

CONCLUSIONS:

Our novel implantation method using transjugular ICE, which enable real-time direct visualization of the membranous septum, achieved a predictably high position of prostheses, resulting in a substantial reduction of conduction disturbances requiring PPI after transcatheter aortic valve implantation.
Sex-Specific Risk Factors of Nonstenotic Carotid Plaque in Embolic Stroke of Unknown Source: A Case-Control Study
Authors: Jochmann Svenja L. , Sievering Esther M.W. , Ernst Johanna , Ringlstetter Rieke , Grosshennig Anika , Weissenborn Karin , Grosse Gerrit M.
Published: December 2023

BACKGROUND:

Many ischemic strokes are diagnosed as embolic strokes of undetermined source (ESUS). Recent evidence suggests that nonstenotic carotid plaque (nsCP) may be a substantial contributor to the risk for ESUS. We aimed to investigate the risk factor profile associated with nsCP in ESUS and defined stroke etiologies.

METHODS:

In this retrospective case-control study, we investigated consecutive patients with acute ischemic stroke due to ESUS, small-vessel disease, or cardioembolism proven by magnetic resonance imaging. The association of vascular risk factors age, arterial hypertension, diabetes, dyslipoproteinemia, body mass index, alcohol consumption, tobacco use, kidney failure, and history of stroke with the presence of nsCP was investigated using binary logistic regression analysis and further stratified by stroke etiology and sex.

RESULTS:

In total, 609 patients (median age, 76 years; 46% women) who were treated from 2018 to 2020 were considered. In patients with ESUS, sex played a more important role for the prevalence of nsCP than in defined etiologies. Female patients with ESUS had lower odds of exhibiting nsCP compared with male patients with ESUS (adjusted odds ratio, 0.36 [95% CI, 0.15–0.86]). In male patients with ESUS, we observed that age (adjusted odds ratio per 10-year increase, 2.55 [95% CI, 1.26–5.17]) and hypertension (adjusted odds ratio, 2.49 [95% CI, 0.56–11.1]) were the main risk factors for nsCP, whereas in female patients with ESUS also tobacco use was particularly relevant (adjusted odds ratio, 3.71 [95% CI, 0.61–22.5]). These results were in line with a sensitivity analysis in nsCP located ipsilateral to the infarct.

CONCLUSIONS:

Sex differences play an important role in nsCP prevalence in patients with ESUS. These findings may have important implications for the management in targeted secondary prevention following ESUS.

Published: December 2023

BACKGROUND:

Reteplase is a more affordable new-generation thrombolytic with a prolonged half-life. We aimed to determine the safety dose range of reteplase for patients with acute ischemic stroke within 4.5 hours of onset.

METHODS:

This is a multicenter, prospective, randomized controlled, open-label, blinded-end point phase 2 clinical trial. Patients with acute ischemic stroke aged between 18 and 80 years who were eligible for standard intravenous thrombolysis were enrolled from 17 centers in China and randomly assigned (1:1:1) to receive intravenous reteplase 12+12 mg, intravenous reteplase 18+18 mg, or intravenous alteplase 0.9 mg/kg. The primary safety outcome was symptomatic intracranial hemorrhage (SITS definition) within 36 hours. The primary efficacy outcome was the proportion of patients with the National Institutes of Health Stroke Scale score of no more than 1 or a decrease of at least 4 points from the baseline at 14 days after thrombolysis.

RESULTS:

Between August 2019 and May 2021, 180 patients were randomly assigned to reteplase 12+12 mg (n=61), reteplase 18+18 mg (n=67), or alteplase (n=52). Four patients did not receive the study agent. Symptomatic intracranial hemorrhage occurred in 3 of 60 (5.0%) in the reteplase 12+12 mg group, 1 of 66 (1.5%) in the reteplase 18+18 mg group, and 1 of 50 (2.0%) in the alteplase group (
P
=0.53). The primary efficacy outcome in the modified intention-to-treat population occurred in 45 of 60 (75.0%) in the reteplase 12+12 mg group (odds ratio, 0.85 [95% CI, 0.35–2.06]), 48 of 66 (72.7%) in the reteplase 18+18 mg group (odds ratio, 0.75 [95% CI, 0.32–1.78]), and 39 of 50 (78.0%) in alteplase group.

CONCLUSIONS:

Reteplase was well tolerated in patients with acute ischemic stroke within 4.5 hours of onset in China with a similar efficacy profile to alteplase. The efficacy and appropriate dosage of reteplase for patients with acute ischemic stroke need prospective validation.

The taxonominal status of the nomina Lesueuria Milne Edwards, 1841 and Lesueuriidae Chun, 1880, and introduction of a new genus and a new family for Lesueuria pinnata Ralph & Kaberry, 1950, as well as an additional new species of the new genus (Ctenophora, Lobata)
Authors: MILLS CLAUDIA E. , DUBOIS ALAIN
Published: December 2023

The nomenclatural problems posed by the nomen of the ctenophore species Lesueuria vitrea Milne Edwards, 1841, type species of the genus Lesueuria Milne Edwards, 1841 which is type genus of the family Lesueuriidae Chun, 1880, and by a few other species long referred to this genus and family, are addressed, and new solutions are proposed for some of them. For the species Lesueuria pinnata Ralph & Kaberry, 1950, an unusual ‘finned’ lobate ctenophore from the southern Pacific Ocean, a new genus and a new family are introduced. It is shown that the nomenclatural problems discussed in this paper raise difficulties for four distinct reasons, related to four different basic concepts of zoological nomenclature: those of ‘name-bearing type’ or onomatophores, of ‘type species’ of genera or nucleospecies, of availability, validity and nomen dubium, and of ‘nomenclatural stability’. The fact that specimens of this group are ‘fragile’ and difficult or impossible to fix and keep in collections requires recourse to indirect methods (detailed description, good iconography and molecular sequencing) applied to ‘ephemeral’ type specimens (holotypes or neotypes) to objectify and stabilize the nomenclature in this group.

Treating Psychosis Today: A Lacanian Take
Authors: Vanheule Stijn
Published: December 2023

This paper examines the principal ideas from Jacques Lacan’s psychoanalytic theory of psychosis. According to Lacan’s theory in the 1950s, the central organizing element of symbolically organized mental life, the Name-of-the-Father, is missing in psychosis. That theory changes with later conceptual developments in Lacan’s work that focus on the incompleteness of symbolic functioning. This connects with how, in his works from the late 1960s and the 1970s, Lacan embraces the idea of a fundamental non-rapport and symbolic non-existence at the basis of mental life. In a second step, the paper explores what the Lacanian model of psychosis implies with regard to ethical positioning, addressing the unconscious, handling transference, and crisis and stability in psychosis. A clinical case discussion focuses on a yearlong therapeutic trajectory with a young man with Down’s syndrome who suffered from psychotic experiences.
The Reception of Lacanian Theory and Practice by American Psychoanalytic Training Programs
Authors: Kirshner Lewis
Published: December 2023

This paper explores the principal reasons for the exclusion of Lacanian ideas from psychoanalytic training institutes in the United States. The history of Lacan’s role in the International Psychoanalytical Association, from which essentially he was expelled, occupies a central place in this story. Significant issues arose also from his practice style and technical innovations, whose rationale remains controversial today. Another major obstacle for the reception of his work is the theoretical framework of Lacanian analysis, so different from that of other schools. Inclusion of its unfamiliar vocabulary and concepts poses practical problems for training programs. At a more fundamental level, the strong antihumanist evolution of Lacan’s thought runs contrary to the increasingly relational and intersubjective orientation of American psychoanalysis. The incompatibility between the disparate languages of a scientific theory aiming at objectivity and a phenomenology of personal intentionality and meaning greatly limits the possibilities for dialogue. The tension between these perspectives cannot be resolved, but a productive exchange between them is possible if they are accepted as valid and complementary ways of speaking about human behavior.
America’s Lacan AprÈs Coup
Authors: Morris Humphrey
Published: December 2023

Lacan’s effect in America was dramatic but limited following his 1975 visit. His polemic with ego psychology in Écrits radically changed the way literary critics, notably feminist critics, thought about psychoanalysis, while in those same years—the 1970s and 1980s—American psychoanalysts, taken up with their own reactions to ego psychology, paid him little attention. Yet après coup, looking back at that period, Lacan can be counted among those who contributed importantly to a major shift in our conception of psychoanalytic process: our contemporary sense of acts of reading—including clinical listening—as acts in themselves, rather than as steps toward the interpretive determination of hidden meaning. In acts of reading inspired by Lacan, feminist critics helped free Freud’s theory of disavowal from its origins in the male anxieties of the castration complex. Speaking as the disavowed “others” of psychoanalysis, Lacan’s feminist readers also went beyond him in moving psychoanalysis toward acknowledgment of questions of social and historical reality, including its own. Regarding this evolution, it can be speculated that hidden behind the bitterness of the split in the 1950s and 1960s between Lacan and the once European, now American ego psychologists can be found an unconscious agreement. On both sides of the Atlantic, psychoanalysis had had its reasons, if different reasons, to disavow for years the ways it was implicated in the unspeakable trauma of recent European history.
A Content Analysis of Transgender Health and Wellness Themes Shared Through Social Media
Authors: Stoody Vishvanie B. , Glick Hannah R. , Murphey Annie C. , Sturza Julie M. , Selkie Ellen M.
Published: December 2023

Transgender and gender-diverse (TGD) adolescents experience limited access to gender-affirming care (GAC) and information and use social media platforms for informational and social support. We conducted conventional content analysis of posts on the platform, Tumblr and applied univariate statistics to characterize health and wellness themes represented by this content. Content was predominantly transmasculine-relevant. Posts addressing the trans health care paradigm often co-occurred with content referencing affirmation logs, the physical and emotional impact of affirmation, surgery, and unspecified medical interventions. Gender-affirming hormone therapy was the most prevalent intervention referenced in posts related to non-professional/non-licensed medical care and advice requests. Transgender and gender-diverse youth-serving individuals can use this information to mitigate harm, enhance patient education, and improve the overall well-being of TGD youth. Further research is needed to characterize the effect of content encountered on social media on pediatric patient experiences and on outcomes of GAC.
Trading Behaviour Exhibited by Institutional Investors During Calm and Volatile Periods in the Indian Scenario
Authors: Singh Amit Kumar , Shrivastav Rohit Kumar , Jain Srishti
Published: December 2023

The stock market is the reflection of the trading pattern of various investors. The present study attempts to examine the trading behaviour followed by foreign institutional investors, domestic institutional investors and mutual funds during 2010–2020 in the Indian stock market. The whole time period is divided into two subperiods using the chow breakpoint test. Two vector autoregression framework models accompanied with impulse response function and variance decomposition analysis are employed in both the subperiods, namely calm period and volatile period. It is found that the institutional investors do not pay heed to the market returns in the calm period, while the interdependency among the institutional investors increases in the volatile period. The structural break enhances the forecasting accuracy of the model significantly. This study will help the government to understand the impact of calm period and volatile period on the trading behaviours of the institutional investors and thereby their sentiments in the Indian stock market.

Global forensic social work education: A cross-national comparison of education models in 10 countries
Authors: Lattas Dimitra , Davis Cindy , Creamer Catherine
Published: December 2023

Unlike qualifying education, forensic social work education is heterogeneous. This review provides a cross-national comparison of 10 countries: the United States, Brazil, England, the Netherlands, Hungary, Kenya, South Africa, Thailand, India and Australia. It aims to understand education models across diverse contexts and encourage further reflection on forensic social work pedagogy. Findings revealed that there is little mandating of educational standards or curriculum requirements in forensic social work. Moreover, current modelling is drawn from Eurocentric epistemologies and has a duty to incorporate and celebrate First Nations, non-Western and culturally inclusive paradigms. Opportunities exist to develop international standards for forensic social work education.
Pericopes in the Present: Gender, Water, and Flows of Blood in and Beyond Mark 5
Authors: Zenner Christiana
Published: December 2023

This essay considers polyvalent meanings of fresh water and the gendered dynamics of menstrual blood and porous, gendered bodies in the history of interpretation of Mark 5:24–35. Drawing upon a hydrosocial, anti-colonial, intersectional feminist hermeneutic, this essay articulates intersections among the uneven contemporary menstrual burdens associated with insufficient fresh water supply, indicates how gendered and racialized medicine and public health figure into these dynamics, and offers a robust alternative to the dominant history of biblical interpretation usually applied to the Mark 5 pericope of the hemorrhaging woman.
Between Colonial and Revolutionary Heritage: Contemporary Political Urban Landscape of São Tomé
Authors: Górny Krzysztof
Published: December 2023

This article tackles the subject of political urban landscape of São Tomé, the capital city of São Tomé and Príncipe. Its aim is to characterise the urban landscape of this city, which has not been previously extensively explored in international literature, in terms of political and historical aspects. As demonstrated by the results of the conducted field research, the contemporary landscape of São Tomé is a system of intertwined components, related to various eras in the islands’ history. On one hand, there are still many traces of Portuguese colonial heritage; on the other hand, there are also plenty of symbolic elements associated with the period of Marxist dictatorship of 1975–1991.
The Compromised Strongman: Interrelationship of Strongman Politics, Radical Rights, and Nationalism in Contemporary Bangladesh
Authors: Ahmed Md. Samzir
Published: December 2023

The strongman is the single key approach to studying the democratic status, the rise of radical rights, and the questions on nationalism in present-day Bangladesh. Occupying the office since 2008, Prime Minister Sheikh Hasina took a sharp turn in 2014 to become a strongman leader of the country, and a successful strongman regime has been created in the process. Since then, the strongman government has made quite a few populist compromises with the radical right groups, which then, in turn, gave birth to a distinct kind of strongmanship: the compromised strongman. This historical research through secondary data analyses finds that a nationalist identity split between a linguistic and a religious, national consciousness has played the role of the major catalyst in the political outcome of the country, and an apparent compromise between the two groups representing the secular and the religious blocks, contrary to common sense, paved the way for the strongman politics in Bangladesh.
Symbolic Annihilation: Analyzing Associated Press’s Erasure of Vanessa Nakate and Marginalization of Black Women Activists
Authors: Hasan Mahedi
Published: December 2023

This study examines the exclusion of Vanessa Nakate, a Ugandan climate activist, from a group photo published by the Associated Press (AP) during the 2020 World Economic Forum. Using the muted group theory, it explores the implications of Nakate’s omission as the sole Black individual in the image, shedding light on the broader issue of symbolic annihilation faced by Black women activists in Western media. Through visual and textual analysis, the study reveals the power dynamics and biases behind AP’s decision to crop Nakate, fueling subsequent controversy. Furthermore, the paper examines AP’s response to the backlash, analyzing their strategies to rebuild their reputation, including issuing an apology and releasing the original photograph.
Documenting Cold War Truth: Human Rights Abuses and Spiritual Death in the USSR and the US
Authors: Roman Meredith L.
Published: December 2023

In the late 1960s and early 1970s, Soviet activists in the USSR and members of the Black Panther Party in the United States emphasized the need to document the truth of domestic human rights abuses not in the land of the Cold War adversary but in their own. In the process, they contested the dominant misrepresentations of Soviet citizens and African Americans that obscured those routine human rights abuses. Members of both groups conceived of documenting this truth as essential to ultimately eliminating these domestic forms of state-sanctioned violence. They also spoke of the act of speaking the truth in word and deed as facilitating their own liberation from what they similarly identified as a devastating Soviet and American spiritual death in countries that were officially represented in the Cold War universe as the moral antithesis. The ‘woke’ or liberated individual was no longer a subservient, mask-wearing ‘Homo Sovieticus’ or ‘Negro’ who mouthed the lies of unbounded Soviet democracy and American freedom, but a genuine citizen and full human being who demanded respect for their human rights.

Authors: Schles Rachel Anne , Fricke Emma , Probst Kristi M.
Published: December 2023

There is wide variability in the special education eligibility criteria for deafblindness across the United States. This study was a novel examination of variations in state factors, including eligibility criteria for deafblindness, to identify potential relationships between state factors and the number of students who are deafblind during the 2018–2019 school year. No state factors correlated to the OSEP Child Count population data. Multiple linear regression analysis revealed factors primarily relating to sensory disability professionals, which correlated to the National Center on Deaf-Blindness population data. Implications for students, personnel, and professional development offerings are discussed.
Moderating Effect of Dyspnea in the Relationship Between Death Anxiety and Self-Management in COPD: A Structural Equation Modeling Analysis
Authors: Aydin Cihan , Ceyhan Yasemin
Published: December 2023

The study was conducted to examine the moderating effect of dyspnea (according to Modified Medical Research Council-mMRC scale) on the relationship between death anxiety (DA) and self-management (SM) levels in patients suffering from chronic obstructive pulmonary disease (COPD) ( n = 313). Model fit indices are within appropriate limits (χ2/DF = 2.284, GFI = .855, CFI = .796, RMSEA = .064). In mMRC 2, females had 33 times more DA than males. In mMRC 3, DA increased 36 times with increasing age and 14 times with comorbidity. It decreased 15-fold in those with past exacerbation experience. The second model explained DA by 18% while the moderating effect of severe dyspnea contributed 28% to this association. In this group of patients, a one unit increase in DA led to a 53-fold increase in SM. Age, gender, comorbidity and previous exacerbation history affect DA in patients with COPD. Increased DA decreases self-management. Severe dyspnea has a moderating effect between DA and SM.

Published: December 2023

In this study, we explore the feasibility and performance of detecting scalp-recorded frequency-following responses (FFRs) with a specialized machine learning (ML) model. By leveraging the strengths of feature extraction of the source separation non-negative matrix factorization (SSNMF) algorithm and its adeptness in handling limited training data, we adapted the SSNMF algorithm into a specialized ML model with a hybrid architecture to enhance FFR detection amidst background noise. We recruited 40 adults with normal hearing and evoked their scalp recorded FFRs using the English vowel/i/with a rising pitch contour. The model was trained on FFR-present and FFR-absent conditions, and its performance was evaluated using sensitivity, specificity, efficiency, false-positive rate, and false-negative rate metrics. This study revealed that the specialized SSNMF model achieved heightened sensitivity, specificity, and efficiency in detecting FFRs as the number of recording sweeps increased. Sensitivity exceeded 80% at 500 sweeps and maintained over 89% from 1000 sweeps onwards. Similarly, specificity and efficiency also improved rapidly with increasing sweeps. The progressively enhanced sensitivity, specificity, and efficiency of this specialized ML model underscore its practicality and potential for broader applications. These findings have immediate implications for FFR research and clinical use, while paving the way for further advancements in the assessment of auditory processing.
Hygiene Behavior and COVID-19 Pandemic: Opportunities of COVID-19-Imposed Changes in Hygiene Behavior
Authors: Ali Adnan Sirage , Yohannes Meseret W. , Tesfahun Tsedey
Published: December 2023

In Ethiopia, the WHO strategies to stop coronavirus transmission were implemented rapidly. As a result, there was a rapid change in hygiene behavior, which are basic for preventing COVID-19 and other contagious diseases. This research was designed to examine the sustainability of the COVID-19 imposed hygiene behaviors for future challenges. The study was conducted in 2 major nexus areas in Addis Ababa. The data were collected using a questionnaire and spot-check from 622 respondents selected by systematic random sampling. The questionnaire was given at every 15th interval in several spots of the site. Observational hygiene-check was done through observing key personal hygiene conditions. Proportion, χ2 test, and Poisson’s regression were applied for the analysis. The χ2-test analyses showed that the hand washing frequency before, during, and post-COVID-19 was statistically significant ( P < .005). Findings from the spot-check also show that the hands of 76.8%, the nails of 68.7%, and the hairs of 70.7% of the respondents were clean. The major driving factors for the rapid changes in hygiene behavior were the awareness developed (95%), the fear and panic (90%), and increased access to water and soap (63%). Nevertheless, the major reasons for failing to continue the COVID-19-imposed good hygiene practice in the post-COVID-19 times include the decline in infection and death rates (26%) and the decline in facility access (20%). Hand washing frequency significantly changed during the COVID-19 pandemic indicating that the practice as part of the preventive strategy was successful. However, as this was mainly due to the fear and panic in the community, the COVID-19 imposed hand washing practice did not bring real and sustainable behavioral changes. This indicates that for long-lasting changes in hygiene behavior, continuous and better approach need to be introduced.

Published: December 2023

Based on the complex aging background, more and more older people have to live in an institution in later life in China. The prevalence of cognitive frailty (CF) is more higher in institutions than in communities. Rarely studies were conducted on the relationship between institutional residence and CF. Hence, this study were performed to determine the relationship between institutional residence (living in a nursing home) and CF in older adults. A total of 1004 older community residents and 111 older nursing home residents over 50 years of age from Hefei, Anhui Province, China were recruited. CF included physical frailty (PF) and mild cognitive impairment (MCI). PF was assessed using the Chinese version of the Fried frailty scale, MCI was assessed using the Montreal Cognitive Assessment, and the common associated factors including sedentary behavior, exercise, intellectual activity, comorbidity, medication, chronic pain, sleep disorders, nutritional status and loneliness were analyzed using regression logistic models. Multivariate regression logistic analysis showed that exercise ( P = .019, odds ratio [OR] = 0.494, 95% confidence interval [CI]: 0.274-0.891), intellectual activity ( P = .019, OR = 0.595, 95% CI: 0.380-0.932), medication use ( P = .003, OR = 2.388, 95% CI: 1.339-4.258), chronic pain ( P = .003, OR = 1.580, 95% CI: 1.013-2.465) and loneliness ( P = .000, OR = 2.991, 95% CI: 1.728-5.175) were significantly associated with CF in community residents; however, only sedentary behavior ( P = .013, OR = 3.851, 95% CI: 1.328-11.170) was significantly associated with CF in nursing home residents. Our findings suggest that nursing homes can effectively address many common risk factors for CF, including lack of exercise and intellectual activity, medication use, chronic pain, and loneliness, better than the community setting. Thus, residing in a nursing home is conducive to the intervention of CF.
Do Envy and Consumer-Generated Content Boost Travel Motivations?
Authors: Dedeoglu Bekir Bora , Colmekcioglu Nazan , Okumus Fevzi
Published: December 2023

This article examines the relationships between consumer-generated content, travel motivation, desire to visit a destination, destination visit intention, and willingness to pay more. This article also analyzes the moderating effect of envy types on these relationships. We collected data from 414 participants in the US. According to the research findings, importance attached to participant sharing (IPS) is a predictor of escape and novelty motivation, while importance attached to non-participant sharing (INPS) is a predictor of exciting experience, novelty, prestige, and self-development motivations. Desire to visit the destination also positively affects destination visit intention and willingness to pay more. Benign envy has a moderating effect on relationships between INPS/IPS and prestige motivation. On the other hand, malicious envy has only a moderating effect on the relationship between INPS and escape motivation. This study reveals that consumer-generated content (CGC) strongly influences intrinsic travel motives. This study also explains how CGC influences attitudes and behaviors in the context of self-determination theory.
Going with the Flow: Moving Cells and Changing Values in Biomedical Practice
Authors: Delvenne Pierre , Macq Hadrien , Parotte Céline
Published: December 2023

Science and technology studies have devoted considerable attention to the economic implications of biomedical technoscience. This article enriches these studies by offering a new reading of several strands of literature to explore how the valuation processes of gifts, commodities, and assets are intertwined in practice. We derive this approach from an empirical analysis of autologous blood donation in the case of a cell therapy called “extracorporeal photopheresis.” Combining ethnographic fieldwork with semi-structured interviews, focus groups, and document analysis in a cell therapy laboratory at a Belgian university hospital, we followed cells in motion from their original donation to their reinjection into the body, observing the practices that constitute and shape their value. We find that the various qualifications as “gift,” “commodity,” or “asset” that cells acquire, accumulate, or relinquish, as well as the consequences of these qualifications, are accessible only by observing the valuation practices that configure living processes. Our analysis highlights the interrelations between the economic forms that living entities can take and rejects the idea of a watertight boundary between them. By emphasizing the entanglement of logics specific to donation, commodification, or assetization, we contribute to linking the value shifts observed at the level of the laboratory to broader capitalist transformations.
Neo-anachronism? The coiled temporalities of South-South media flows
Authors: Kraidy Marwan M
Published: December 2023

This article mobilizes Jesus Martín Barbero’s magnum opus, Communication, Culture, and Hegemony, towards a better understanding of the contemporary global success of Turkish television drama, known as dizi, in Latin America, the land of the once-mighty telenovela. Hilighting Martín-Barbero’s centrality to my own intellectual project on the transnational connection and transcultural resonances between the Middle East and Latin America, I draw on preliminary fieldwork in Argentina and Mexico, where Turkish dizi have been hits, to revisit Martín-Barbero’s pivotal conceptualization of mediaciones and accounts for forces of global media competition, aesthetic mimicry, and the fundamental problematic of South-to-South relations that got a new lease on life with the success of dizi in Latin America. Ultimately, I probe Martín-Barbero’s “precious anachronism” to elaborate a notion of “coiled temporality” that emerges between different geocultural zones through the consumption of narrative television fiction.
CrossFit and “Cancel Culture”: Probing Practitioners’ Responses to the “Canceling” of Greg Glassman
Authors: Spencer Dale , Silva Derek , DiTecco Delphine , West Carmen
Published: December 2023

In this article, we explore the responses of crossfit practitioners to the ‘canceling’ of Greg Glassman in the aftermath of racist tweets and comments made in response to the killing of George Floyd. We draw on 50 interviews with crossfit practitioners to understand how they interpret and respond to the ‘canceling’ of Greg Glassman and the disavowal of CrossFit by prominent CrossFit athletes and organizations. We probe how athletes, regardless of levels of involvement, in the wake of Glassman's comments respond to the refiguring of the sporting community of CrossFit. A cancel culture continuum from affirmation to rejection emerged from the interview data that typified their views of cancel culture, Greg Glassman's removal from CrossFit HQ, and the current state of the sport. We conclude with a discussion of the phenomena of canceling or cancel culture and reflects on crossfit as a sport in light of the Glassman affair.

Environmental justice (EJ) scholarship has long done work in and on Black communities. Yet, the field’s engagement with critical race studies has been rather recent and limited. This paper questions what we learn about Black living from EJ scholarship. I argue that there are two main registers of Black living in EJ scholarship: dying and activism. I draw on Black feminist geographies to think and imagine EJ work that incorporates nuance to the modalities of Black life and futurity in the face of state-sanctioned environmental injustice. The goal of this is not to deter EJ scholars from exposing instantiations of environmental injustice in the world, nor to undermine the deadly realities of EJ communities. Rather, this paper pushes EJ scholars to be wary of essentializing Black communities to death and decay and urges these scholars to behold Black life and futurity experienced in close proximity to death in these spaces. I provide examples of Black living and making way for Black futurity that occurs beyond the registers of dying and activism in EJ communities, such as care, Black intellectual life, and refusal, registers made apparent through a Black geographies lens.
Imagining Contagion: Epidemic, Prisons, and Franco Spain's Politics of Space, 1936–1945
Authors: Richards Michael
Published: December 2023

Recent accounting for disease in the aftermath of the Spanish Civil War has been contained within study of hunger in the early 1940s. Historians have cited the typhus epidemic which hit Spain between 1939 and 1945 as demonstrating a causal link between widespread semi-starvation and disease. Though important, the focus on hunger risks losing sight of other vital elements in the onset and transmission of typhus, however, as well as the way the epidemic's progress sheds light on population movement as central to the broader social history of the war and its aftermath.

By paying close attention to epidemiological records, this article argues that the direct causes of typhus and its vertiginous spread were primarily ideological and spatial. It shows first how the war's victors used the language of political and bacterial contagion to claim spuriously that the wartime Republic was responsible for the epidemic. It then demonstrates how the intense confinement on a huge scale of those linked to the Republic was at the root of the disease. Transmission depended on this mass imprisonment and on the increased circulation of families to support those in captivity. Finally, typhus influenced the social imagination of the Franco regime and its anxiety about hygiene, prisons, and control of the movement of the urban poor.

Digital platforms provide organizations with new ways to conduct sourcing activities. Crowdsourcing has emerged as one potential method of sourcing various kinds of information technology (IT) services. Notwithstanding the benefits of IT crowdsourcing services (ITCSs), there is a lack of clarity about why some firms procure services through ITCS, whereas others do not. Drawing on the organizational capabilities perspective, we hypothesize that in-house IT administration capability and IT flexibility jointly enhance a firm’s ITCS Platform Suitability Assessment, which, in turn, leads to higher ITCS Service Procurement. We also posit that ITCS Platform Suitability Assessment mediates the relationship between IT Administration Capability and ITCS Service Procurement. Our empirical analysis of survey data from 308 firms in the United States supports our hypotheses. Our results suggest that firms that develop IT administrative capabilities and IT flexibility assess ITCS platform characteristics as more suitable for ITCS-related activities. ITCS Platform Suitability Assessment, in turn, drives firms to procure operational services (e.g., setting up automatic payments) and strategic services (e.g., project management) from the loose configuration of workers in the gig economy. Our results contribute to theory by positing and testing a theoretical model that expands the theoretical base used to explain ITCS sourcing. We discuss the implications for the business value of IT platforms, organizational structure, and capabilities in regard to future sourcing strategies.

Published: December 2023

Since the dawn of digital art, discourse regarding its potential persists. This research investigates how a virtual reality (VR) art gallery impacts positive and negative affect, examining the influences of aesthetic experiences and individual characteristics. It explores the connection between measures of aesthetic experiences (self-assessed, heart rate, and heart rate variability) and how gender influences this relationship. Digital art's beneficial effect is indicated by decreased negative affect after visiting the VR gallery, potentially influencing mental wellbeing. Individual characteristics influence this impact on affect after the VR experience, especially openness to experience and affect before the visit, mediated by aesthetic experience, and expertise mediated by heart rate. The findings highlight the potential impact of gender on subjective interpretations of physiological responses in the VR environment. Specifically, women tend to attribute heightened heart rate, a sign of arousal, while men associate increased heart rate variability, a sign of relaxation, to positive experiences in the VR.

Traumatic portal vein injury is rare, but the associated mortality rate ranges from 50% to 70%. The management of this injury is difficult and remains controversial. In this case report, we describe the successful endovascular treatment of an obstruction that developed following the surgical repair of a traumatic portal vein injury. A man in his mid-40s who had been injured in a car accident presented to our trauma center with abdominal pain, abdominal distension, and open wounds over both knees. Emergency laparotomy revealed a longitudinal rupture from the upper border of the pancreas to the mid-portion of the portal vein; his hemorrhage was successfully controlled surgically. However, postoperative abdominal computed tomography imaging revealed portal vein obstruction. One week after admission to the intensive care unit, an endovascular stent was successfully inserted into the patient’s portal vein via a percutaneous transhepatic approach. The associated injuries, including the distal common bile duct obstruction, were successfully managed by choledochojejunostomy. The patient’s postoperative recovery was uneventful. Thus, endovascular stent placement is an effective and safe means of treating an obstruction following the surgical repair of a traumatic portal vein injury.

While the immunodeficient status of NOD.Cg- Prkdc scid Il2rg tm1Wjl/SzJ (NSG) and NSG-related mice provides utility for numerous research models, it also results in increased susceptibility to opportunistic pathogens. Over a 9-week period, a high rate of mortality was reported in a housing room of NSG and NSG-related mice. Diagnostics were performed to determine the underlying etiopathogenesis. Mice submitted for evaluation included those found deceased ( n = 2), cage mates of deceased mice with or without diarrhea ( n = 17), and moribund mice ( n = 8). Grossly, mice exhibited small intestinal and cecal dilation with abundant gas and/or digesta ( n = 18), serosal hemorrhage and congestion ( n = 6), or were grossly normal ( n = 3). Histologically, there was erosive to ulcerative enterocolitis ( n = 7) of the distal small and large intestine or widespread individual epithelial cell death with luminal sloughing ( n = 13) and varying degrees of submucosal edema and mucosal hyperplasia. Cecal dysbiosis, a reduction in typical filamentous bacteria coupled with overgrowth of bacterial rods, was identified in 18 of 24 (75%) mice. Clostridium spp. and Paeniclostridium sordellii were identified in 13 of 23 (57%) and 7 of 23 (30%) mice, respectively. Clostridium perfringens (7 of 23, 30%) was isolated most frequently. Toxinotyping of C. perfringens positive mice ( n = 2) identified C. perfringens type A. Luminal immunoreactivity to several clostridial species was identified within lesioned small intestine by immunohistochemistry. Clinicopathologic findings were thus associated with overgrowth of various clostridial species, though direct causality could not be ascribed. A diet shift preceding the mortality event may have contributed to loss of intestinal homeostasis.

Safe railway operation is vital for public safety, the environment, and property. Concurrent with climbing amounts of rail traffic on the Canadian rail network are increases in the last decade in the annual crash counts for derailment, collision, and highway railroad grade crossings (HRGCs). HRGCs are important spatial areas of the rail network, and the development of community areas near railway tracks increases the risk of HRGC crashes between highway vehicles and moving trains, resulting in consequences varying from property damage to injuries and fatalities. This research aims to identify major factors that cause HRGC crashes and affect the severity of associated casualties. Using these causal factors and ensemble algorithms, machine learning models were developed to analyze HRGC crashes and the severity of associated casualties between 2001 and 2022 in Canada. Furthermore, spatial autocorrelation and optimized hotspot analysis tools from ArcGIS software were used to identify hotspot locations of HRGC crashes. The optimized hotspot analysis shows the clustering of HRGC crashes around major Canadian cities. The analysis of cluster characteristics supports the results obtained for causal factors of HRGC crashes. These research outcomes help one to better understand the major causal factors and hotspot locations of HRGC crashes and assist authorities in implementing countermeasures to improve the safety of HRGCs across the rail network.

The objective of the present study was to test the effects of an inpatient management system (CircadianCare) aimed at limiting the negative impact of hospitalization on sleep by enhancing circadian rhythmicity. Fifty inpatients were randomized to either CircadianCare ( n = 25; 18 males, 62.4 ± 1.9 years) or standard of care ( n = 25; 14 males, 64.5 ± 2.3 years). On admission, all underwent a full sleep-wake evaluation; they then completed daily sleep diaries and wore an actigraph for the whole length of hospitalization. On days 1 (T0), 7 (T1), and 14 (T2, if still hospitalized), salivary melatonin for dim light melatonin onset (DLMO) and 24-h skin temperature were recorded. In addition, environmental noise, temperature, and illuminance were monitored. Patients in the CircadianCare arm followed 1 of 3 schedules for light/dark, meal, and physical activity timings, based on their diurnal preference/habits. They wore short-wavelength-enriched light-emitting glasses for 45 min after awakening and short-wavelength light filter shades from 18:00 h until sleep onset. While the first, primary registered outcome (reduced sleep-onset latency on actigraphy or diary) was not met, based on sleep diaries, there was a trend (0.05 <  p < 0.1) toward an advance in bedtime for CircadianCare compared to standard of care patients between T0 and T1. Similarly, DLMO time significantly advanced in the small group of patients for whom it could be computed on both occasions, with untreated ones starting from earlier baseline values. Patients sleeping near the window had significantly higher sleep efficiency, regardless of treatment arm. As noise fluctuation increased, so did the number of night awakenings, regardless of treatment arm. In conclusion, the CircadianCare management system showed positive results in terms of advancing sleep timing and the circadian rhythm of melatonin. Furthermore, our study identified a combination of environmental noise and lighting indices, which could be easily modulated to prevent hospitalization-related insomnia.
