Abstract
Objectives
Radical prostatectomy (RP) is a common intervention in patients with localized prostate cancer (PCa), with nerve-sparing RP recommended to reduce adverse effects on patient quality of life. Accurate pre-operative detection of extraprostatic extension (EPE) remains challenging, often leading to the application of suboptimal treatment. The aim of this study was to enhance pre-operative EPE detection through multimodal data integration using explainable machine learning (ML).

Methods
Patients with newly diagnosed PCa who underwent [68Ga]Ga-PSMA-11 PET/MRI and subsequent RP were recruited retrospectively from two time ranges for training, cross-validation, and independent validation. The presence of EPE was measured from post-surgical histopathology and predicted using ML and pre-operative parameters, including PET/MRI-derived features, blood-based markers, histology-derived parameters, and demographic parameters. ML models were subsequently compared with conventional PET/MRI-based image readings.

Results
The study involved 107 patients, 59 (55%) of whom were affected by EPE according to postoperative findings for the initial training and cross-validation. The ML models demonstrated superior diagnostic performance over conventional PET/MRI image readings, with the explainable boosting machine model achieving an AUC of 0.88 (95% CI 0.87–0.89) during cross-validation and an AUC of 0.88 (95% CI 0.75–0.97) during independent validation. The ML approach integrating invasive features demonstrated better predictive capabilities for EPE compared to visual clinical read-outs (Cross-validation AUC 0.88 versus 0.71, p = 0.02).

Conclusion
ML based on routinely acquired clinical data can significantly improve the pre-operative detection of EPE in PCa patients, potentially enabling more accurate clinical staging and decision-making, thereby improving patient outcomes.

Critical relevance statement
This study demonstrates that integrating multimodal data with machine learning significantly improves the pre-operative detection of extraprostatic extension in prostate cancer patients, outperforming conventional imaging methods and potentially leading to more accurate clinical staging and better treatment decisions.

Key Points

Extraprostatic extension is an important indicator guiding treatment approaches.

Current assessment of extraprostatic extension is difficult and lacks accuracy.

Machine learning improves detection of extraprostatic extension using PSMA-PET/MRI and histopathology.

Abstract
Background
Radiologic evaluation is crucial in minimizing transplant complications and guaranteeing the donor’s safety, as a variety of anatomical variations characterizes hepatic vascularity. Computed tomographic angiography (CTA) is the gold standard in hepatic vascularity evaluation in donors before liver transplantation. Still, the procedure necessitates intravenous contrast medium injection, which entails nephrotoxicity risk and hypersensitivity reactions. These concerns about contrast medium safety encouraged new developments in non-contrast-enhanced magnetic resonance angiography (NC-MRA) techniques for imaging the vascular anatomy of the liver.

Results
This study was conducted on 40 patients of potential liver donors. Thirty-six cases (90%) showed excellent image quality by CTA versus 14 cases (35%) by NC-MRA; on the other hand, 21 cases (52.5%) showed good image quality by NC-MRA while versus 2 cases (5%) by CTA and NC-MRA documented 5 cases (12.5%) with fair image quality versus two cases documented by CTA. Both modalities provided diagnostic image quality in all cases. Michel’s classification was employed to identify four distinct kinds of hepatic artery anatomy using CTA. Thirty-nine cases out of 40 were successfully identified using NC-MRA. Segment IV hepatic artery origin could not be identified in 6 cases using NC-MRA versus one case using CTA. Artifacts were noted in 20 cases (50%) using NC-MRA versus 2 cases (5%) using CTA.

Conclusion
CTA is the gold standard for pre-liver transplant donor evaluation. The emerging technology of non-contrast MRA has an added value with fewer patient complications. It may function as an additional donor examination when CTA is unable to provide adequate diagnostic information. Non-contrast MRA yields reliable results and eliminates the necessity for contrast medium and additional radiation exposure.
Politicizing Ethics
Authors: Ali Zahra 
Published: December 2024

Abstract
Drawing on critical feminist and decolonial perspectives, this article takes research on Iraq as a framework to raise essential questions about politics and geopolitics of knowledge production and about what constitutes the global academy today. It analyzes the structural, infrastructural, and political dimensions that led to Iraq being researched and theorized outside of its borders, and it highlights the systemic inequalities existing between scholars based in the United States and scholars based in Iraq. The article also questions the production of knowledge and the development of research agendas stemming from institutions based in and tied to an imperial power that has destroyed the very possibility of the existence of a robust academic life in Iraq. It also proposes an alternative research imaginary that politicizes research ethics by putting justice and equality over an obsession for research.
Lyric Lifeforms
Authors: Hartman Meghan 
Published: December 2024

Abstract
This article works toward a theory of lyric in the literary corpus of Mīrājī (1912–1949), an Urdu poet, translator, and critic. The article argues that the lyric is an especially salient place to evaluate the phenomenality of such a relationship between self and world, and it is borne through a particular relationship to temporality. It draws this claim from three sources across Mīrājī’s literary corpus: his essay titled “About my Poems” (“Apnī Naẓmon Ke Bāre Men”); his literary critical essay on Sanskrit philosophers of aesthetics titled “Theories on Rasa” (“Ras Ke Naz̤ariye”); and the poem “The Caves of Ajanta (Ajanta ke Ghār).” The article develops a theory of “lyric lifeforms” to encapsulate two features of lyric: 1) how reading and writing lyric can be an experiential and experimental method to (trans)form oneself by redirecting attention and building habits and new appetites of perceiving, specifically through the recognition of shifts in different experiential contexts (such as the sense of return to an ordinary realm after deep absorption in a literary work); and 2) how making oneself requires making a world. Along the way, the article argues that Mīrājī’s approach to lyric becomes legible through his engagement with Hindu and Buddhist cosmological concepts.
Ethics of Knowledge Extraction and Production
Authors: Ababneh Sara 
Published: December 2024

Abstract
This reflection on the politics and ethics of social research in Jordan starts with the dynamics between individual researchers and then turns to the politics and policies of data ownership in funded projects. The power relations between individual researchers as well as those between foreign donors and local researchers indicate who is considered the producer of knowledge and who the owner of it. The essay draws on personal experiences from the author's work in Jordan to think through what this means in terms of power/knowledge structures on the ground and what can be done to resist and transform these dynamics.
Confronting Silence and Cover-Up of the Colonial Genocide in Libya
Authors: Ahmida Ali Abdullatif 
Published: December 2024

Abstract
This short article reflects the author's thinking on the ethics of silence and the recovery of the history of the concentration camps, based on fifteen years of research among the survivors’ oral and folk histories. It challenges the ethics of the dominant colonial historiographical paradigm in Middle East and North Africa scholarship, which is based on the myth that Italian Fascism did not encompass acts of genocide and mass murder and was, therefore, less evil than the fascism practiced under the German Nazi regime. It focuses on the problems of cover-up and the persistence of silence in the social sciences today. Finally, it proposes an alternative view on decolonizing the social sciences and historiography and on decentering future ethical research. This article presents a history of fascist genocide in Libya and Italy based on the agency and a narrative of the Libyans who survived the concentration camps between 1929 and 1934, and it offers suggestions for a new decolonized research agenda based on a critical model of Italian Fascism.
Monumentality and Its Discontents
Authors: Arnold David 
Published: December 2024

Abstract
Connoting immensity of scale, the aura of power, and the ambition to create a highly visible presence and lasting legacy, monumentality was a cardinal attribute of British India's scopic regime and the self-legitimization of imperial rule. From the 1850s onward, monumentality was central to colonial photography, whether through the archiving of precolonial edifices or, increasingly, through the visual representation and reproduction of colonial public works and engineering projects. In focusing on hydraulic engineering, especially canal building and bridge construction, and by citing the work of Samuel Bourne and other colonial photographers including engineers, this article argues for the constitutive role of photography in the making of colonial monumentality, in the creation and circulation of monumental imagery, in pacification and memorialization, and in the exercise of hegemonic power and scalar authority. It assesses the practical as well as the polemical uses of monumental image-making, the transmissibility of images, and the scope photography allowed for, or denied to, monumentality's multiple “discontents” (its obstacles, antitheses, and subversions) and for alternative readings of monumental power.
Precarious Songs

Abstract
This article investigates multiple sources for the theory and criticism of the taṉippāṭal, a premodern genre of short poetic utterance in Tamil. It argues that although scholars have focused on Tamil scholastic discourse as a source for literary knowledge, certain genres like the taṉippāṭal are better understood through applied literary criticism. The first part of the article discusses the evidence for a theory of the taṉippāṭal within the scholastic works of Tamil grammars (ilakkaṇam) and rhetoric texts (pāṭṭiyal), uncovering a formal concept of genre. The second part reconstructs Tamil taṉippāṭal criticism through close readings of lives of poets (carittiram), which narrativize the poetic utterance within a rhetorical event. It discusses how this critical style reveals a unique theory of the lyric. Finally, the article considers the possibilities and limits of using South Asian styles of literary criticism for both reading individual poems and theorizing genre. It proposes that continued research on comparative literary criticisms is productive for mediating the current methodological demands of area studies and comparative literary studies.
Edging on Formlessness
Authors: Silhol-Macher Lou 
Published: December 2024

Abstract
In 2013, the artist now known as American Artist changed their legal name to a generic singular, making themselves impermeable to authorial identification. Manifesting both their official entry in the art world and a withdrawal from it, this name change literally hacked Artist into the white American art canon, as their work now appears alongside Jackson Pollock's or Edward Hopper's in an internet search. This performative act was only the first in a series investigating issues of recognizable form and practices of identification. In 2021 Mother of All Demos II, a computer encased in dirt, the main piece in Artist's installation Black Gooey Universe, fringed on material formlessness as black goo oozed out of the keyboard, spilled over the desk and into the white box of the gallery space, its viscous drops suspended midair, rewriting the racial history of computer technology. This article traces these refusals of form in American Artist's Black Gooey Universe. Drawing on Zakiyyah Jackson's analysis of Western ontology, the article theorizes the edges in Artist's sculptures as sites of undoing, suspension, and speculation. Undoing the form of the GUI to find the “gooey,” Artist's installation ties an archaeological reframing of technology to a reimagining of anticolonial cosmology.
Play It Again (On Catastrophic Storytelling)
Authors: Cramer Lauren Mcleod 
Published: December 2024

Abstract
This introduction describes catastrophizing as a kind of storytelling, a way of gathering events into a narrative of continuity and discontinuity that, when skillfully deployed, is an expression of shifts in thought. Beginning with two short stories about the rise and fall of catastrophe theory, which enjoyed brief mainstream popularity in the 1970s, and the liquid blackness journal's own history of exploring catastrophe, this introduction suggests catastrophizing is a self-reflexive scholarly and creative practice. Disciplines tell catastrophic tales to indicate when and where modes of inquiry and their forms of expression start and stop. Black studies, for example, assumes it plays a considerable role at the beginning of the end of the world; as such, the scholarly contributions to ecocriticism, performance studies, computing, queer theory, and abolition studies that appear in this issue are all methodological experiments that begin at “the end.”
Ca$h App Connectivities
Authors: Hernandez Jillian 
Published: December 2024

Abstract
This article studies how contemporary Black southern cultural production undermines racial and gendered structures of exploitation and foments radical sites of relation by claiming worth under alternative schemes of value that center Black life and demand payment — “cash app me.” The analysis reads with scholar-artist Chaz Barracks's ($Chaz-Antoine) 2020 film Everyday Black Matter and rap duo City Girls’ 2020 antiwork anthem and video “Jobs.” This writing performs an audacious gathering as it is submitted in tandem with Barracks's article for this issue, which offers “con-artistry” as a theory of queer Black joy. This text joins Barracks's con-artistry with my conception of high-maintenance feminism, which describes a contemporary cultural movement in which Black femmes assert their value beyond the confines of respectability and demand what is due to them financially and otherwise within the exploitative context of racial capitalism. The article draws from the standard definition of high-maintenance as “needing a lot of work to keep in good condition” and extends this meaning to describe the depleting physical, mental, emotional, economic, and metaphysical strains placed upon Black femmes under anti-Black conditions, and the considerable care work and remuneration required to survive these strains and access enjoyment.
Renee Royale's Landscapes of Matter
Authors: Young Allison K. 
Published: December 2024

Abstract
In 2021, New Orleans–based artist Renee Royale sojourned to Venice, Louisiana—the terminus of walkable land (referred to locally as “the End of the World”) where the Mississippi River meets the Gulf of Mexico. Surrounded by marshes, human-made canals, and sprawling petrochemical campuses, Royale documented defunct buildings, polluted coasts, and barren trees with a Polaroid camera while collecting water, soil, and flora from each photographed site. The Polaroids were later submerged in jars containing this ecological debris, causing the images to peel, bubble, discolor, and decay. For the artist, the transformed exposures both witness and communicate the stories told by this landscape—indeed, she sees the environment as their cocreator. This article analyzes Renee Royale's work through the lens of ecocriticism and diaspora aesthetics and argues for its symbolic potential to express intersectional histories of violence and climate emergency in the Gulf of Mexico and circum-Caribbean. Reading her photographs as reflective of the Plantationocene condition, the article also considers questions of Black futurity and aftermath, affiliating Royale's practice with Afrofuturist propositions that seek alternate modes of survival beyond racial capitalism.
Some Kind of Liberties
Authors: Alexander Chanaa  
Published: December 2024

For over a decade, between 1906 and 1917, Russia was technically governed under the first-ever Russian Constitution: the Fundamental Laws of 1906. In reality, however, Tsar Nicholas II and his ministers consistently violated the Constitution and conducted affairs as if it didn’t exist— resulting in Early Russian Constitutionalism devolving into “Sham Constitutionalism”. Societal indifference to these violations, especially to the dissolving of the First Duma, played a pivotal role in allowing “Sham Constitutionalism” to develop. As a result of certain social pressures— such as autocratic traditions, a lack of legal consciousness, and a divided, nascent public sphere—Russian society was too indifferent to play a pivotal role in upholding the First Constitution.
CLINICAL OUTCOMES OF STEMLESS ANATOMIC TOTAL SHOULDER ARTHROPLASTY (TSA) IN THE RETROVERTED GLENOID AND COMPARISON WITH TSA IN THE NON-RETROVERTED GLENOID

Published: December 2024

ObjectiveWe aimed to analyse the clinical outcomes and survivorship of anatomic total shoulder arthroplasty using a stemless humeral component with cemented pegged polyethylene glenoid performed with the technique of eccentric reaming to partially correct retroversion. These results were then compared with TSA using the same implant for end-stage shoulder arthritis with a normal version of the native glenoid.Design and methodsA retrospective case series was performed using a prospectively collected database of anatomic TSA patients operated at Woodend General Hospital, Aberdeen, UK. Between 2010 and 2019, 107 total shoulder arthroplasties (TSA) were done using standard anatomic stemless TSA implants (Affinis Short, Mathys Ltd, Bettlach, Switzerland) in 98 patients. Standardized preoperative and postoperative shoulder radiological imaging for glenoid retroversion was collected. Depending on the angle of native glenoid version, patients were divided into retroverted and non-retroverted glenoid as per the Walch Classification. To assess the radiological outcome at the final follow-up, radiolucency was assessed on the glenoid and humeral side using the Lazarus grading. The final clinical and radiologic outcome from the retroverted group was compared with the population with a non-retroverted glenoid. Five TSAs were excluded from the analysis as they did not have satisfactory postoperative radiographs. Hence, a total of 102 shoulders were available for analysis.ResultsThe mean follow-up was 3.48 years (2-10.2 years) in the retroverted group (n=44) and 3.9 years (2-8.9 years) in the non-retroverted group (n=58). The mean pre-operative retroversion of the glenoid in the retroverted group was 20.18, and the post-operative retroversion was 15.87, with a mean correction of 4.31. There was no significant difference between the two groups in the percentage of radiological loosening. The mean Oxford shoulder score was 41.4 (16-48) in the retroverted group, while it was 42.1 (20-48) in the non-retroverted group. Three patients in the retroverted group required revision surgery for rotator cuff failure. There were no revisions for aseptic loosening or instability.ConclusionThe degree of severity of retroversion of the glenoid was not associated with poor clinical outcomes, revisions, or failure in stemless TSA. At medium-term follow-up, partial correction of retroversion seems to provide comparable outcomes compared to a non-retroverted glenoid.

Published: December 2024

ObjectivesOur aim to study the incidence, demographics, inpatient stay, use of imaging and outcomes of patients who have non-operatively managed NOF fractures.Study Design & MethodsThe data was collected retrospectively for the last 14 years (Jan 2009- Jan 2023) of all non-operatively managed NOF fractures at a level 2 trauma centre. The data was collected from the trauma board, electronic patient records, radiographs, and National Hip Fracture Database (NHFD). The data collected as demographic details, fracture classification, any reasons for non-operative management, mortality and further surgical management was done. Patients who died or transferred to other sites for specialist surgery were excluded.ResultsOur results showed that 1.7% (62/4132) of NOF fractures were managed non-operatively at our institution. The reasons for non-operative management were as follows, medically unwell 45% (n = 28) in whom operative risk was thought to outweigh benefit and risk of death was high within the 48 - 72 hrs of admission. The second group patients, minimal or no pain and old fractures with comfortable mobilisation 55% (n = 34). Out of 34 /62 patients who were mobilised, 14% (5/34) of this patient subgroup subsequently required surgical intervention for failed non-operative management. In the medically unwell group (28/62) the 30-day mortality was 32% (12/28) with a 1-year mortality rate of 42% (17/28). The patients who were mobilised (34/62) the 30-day mortality was 6% (4/34) with a 1-year mortality rate of 20% (5/34). The combined average 1 year mortality for this cohort was 35% (22/62).ConclusionsOur study showed higher mortality rate for medically unwell group 42%. The patients whose fractures are stable enough to allow them to mobilise comfortably showed 20% 1-year mortality rate and 14% surgical intervention needed in 14 % (5/34) patients. We note that an analysis is necessary to assess the functional outcomes of this subgroup, as well as the potential cost implications. The combined average 1 year mortality for this cohort was 35% (22/62) which was due to the high-risk factors in medically unwell group.
