Commercial AI Model Diagnostic Accuracy for Intracranial Large- and Medium-Vessel Occlusion in Emergency CT Angiography

The diagnostic accuracy of AIDOC-VO, the first commercial artificial intelligence tool for intracranial large-and medium-vessel occlusion (LVO/MeVO) detection on head-and-neck CT angiography (CTA), was evaluated in a multicenter emergency setting. A prospective diagnostic-accuracy study of 3,031 adult CT angiograms (mean age, 67.3 years ± 16.4 [SD]; 1,549 females) acquired March-July 2024 across a

Gold in Ghana : The effects of changes in large-scale mining on artisanal and small-scale mining (ASM)

Two scales of gold mining operations, artisanal and small-scale mining (ASM) and large-scale mining, have operated side by side in Ghana for decades. In the past, the two co-existed on the same mineralised land without much contact or conflict, as large-scale mining occurred underground and ASM operated mainly on the surface. With the former's transition from an underground labour-intensive mining

Migration, housing and attachment in urban gold mining settlements

Mining settlements are typically portrayed as either consisting of purpose-built housing constructed by mining companies to house their workers, or as temporary makeshift shelters built by miners working informally and inhabited by male migrants who live dangerously and develop little attachment to these places. This paper contributes to these debates on the social and material dynamics occurring

Transitions to adulthood among young entrepreneurs in the informal mobile telephony sector in Accra, Ghana

The rapid expansion of the mobile telephony sector in African countries has been accompanied by the establishment of a wide range of informal support businesses, mostly run by young people. Little is known, however, about the lived experiences of young entrepreneurs working in this rapidly changing, technologically-driven sector. Drawing on qualitative research conducted in Accra, this paper explo

Spatial and social transformations in a secondary city : the role of mobility in Sekondi-Takoradi, Ghana

Existing research on urban Ghana mainly focuses on processes occurring within the country’s major cities, thereby reproducing a trend within the social sciences to overlook the role of intermediate and secondary cities. This paper aims to address this shortcoming by exploring spatial and social transformations in Sekondi–Takoradi, one of Ghana’s secondary cities and the metropolitan area serving t

Expanding the scales and domains of (in)security : Youth employment in urban Zambia

Most research on issues of (in)security has tended to have a military/safety angle and focus on global/national scales linked to spectacular events. This paper addresses the overlooked insecurity realities of urban dwellers in the global South through a focus on more persistent and enduring forms of employment insecurities among young people. Building on both quantitative and qualitative data coll

Association between habitual dietary taurine intake and the risk of metabolic dysfunction-associated steatotic liver disease : a prospective cohort study

Taurine, an amino sulfonic acid abundant in seafood and meat, has been proposed to have a potential role in the prevention of metabolic dysfunction-associated steatotic liver disease (MASLD) due to its antioxidant and anti-inflammatory properties. However, the association between dietary taurine intake and MASLD remains unclear in human populations. Also, data on dietary taurine intake among adult

Molecular and morphological data clarify the phylogenetic position of genera formerly classified in Oenochrominae sensu lato (Lepidoptera: Geometridae)

Oenochrominae sensu stricto (s. s.) are a group of robust-bodied geometrid moths found in the Australasian region. However, over the years, there has been a tendency to relegate genera that are difficult to classify under other subfamilies of Geometridae into a taxonomic “trash bin,” referred to as Oenochrominae sensu lato (s. l.). Here, we examine this assemblage of moths, focusing on Australasia

Monitoring and moderating extreme indoor temperatures in low-income urban communities

Climate change presents significant threats to human health, especially for low-income urban communities in the Global South. Despite numerous studies of heat stress, surprisingly little is known about the temperatures actually encountered by people in their homes, or the benefits of affordable adaptations. This paper examines indoor air temperature measurements gathered from 47 living rooms withi

Glutathione responsive iNOS inhibiting polymeric prodrug for targeted Inhibition of angiogenesis

Background: Inducible nitric oxide synthase (iNOS) is a key driver of aberrant angiogenesis in inflammatory conditions and cancer, making it an attractive therapeutic target. Nevertheless, its function can be affected by the complex immune responses and tumor microenvironment (TME). Hence, combinatorial treatment approaches that simultaneously target iNOS and immune-modulatory signaling are strong

‘We are at the mercy of the floods!’ : Extreme weather events, disrupted mobilities, and everyday navigation in urban Ghana

This paper examines how extreme weather events affect the mobility of low-income urban residents in Ghana. Bringing together scholarship on extreme weather and mobilities, it explores the differential impact of flooding on their everyday lives as they navigate the cities of Accra and Tamale. A range of qualitative methods were drawn on, including semi-structured interviews, focus group discussions

Shaping Geographies of Informal Education : A Global South Perspective

This article aims to shape understandings of the geographies of informal education by exploring an aspect of education that has been broadly overlooked by geographers to date—apprenticeships—within a Global South context. Drawing on qualitative research conducted in Accra, Ghana, where young male and female apprentices learn a trade alongside master craftspeople, the nature of the apprenticeship s

‘We built this city’ : Mobilities, urban livelihoods and social infrastructure in the lives of elderly Ghanaians

This article examines the experiences of an often-neglected population group in geographical scholarship, namely, elderly people living in African cities. Using qualitative research conducted in the Ghanaian cities of Accra and Sekondi-Takoradi, we demonstrate how investigating older people's mobilities, and examining how they influence social and economic processes, has important implications for

Disrupted becomings : The role of smartphones in Syrian refugees’ physical and existential journeys

This paper explores the role of smartphones in facilitating the journeys of predominantly young, male Syrians following the onset of the civil war. Drawing on in-depth interviews conducted with Syrian refugees who have reached Denmark but are at different stages of the asylum process, it traces the multiple disruptions they have experienced and delves into the ways in which they navigate in their

Early Prophylactic Hydrocortisone and Bronchopulmonary Dysplasia–Free Survival in Extremely Preterm Infants

Importance In randomized trials, early prophylactic hydrocortisone improved survival without bronchopulmonary dysplasia (BPD) with few adverse effects in extremely preterm infants. Large scale implementation data are needed to evaluate clinical effects and safety. Objective To examine the association between early prophylactic hydrocortisone and survival without BPD at 36 weeks’ postmenstrual age

Sand-swimming behaviour reduces ectoparasitism in an iguanian lizard

Sand swimming behaviour occurs in several lizard clades. Known ecological advantages of sand swimming include reduced predation risk and enhanced thermoregulation. We addressed whether, by way of sand abrasion, sand-swimming reduces ectoparasitism in the lizard Microlophus occipitalis, whose natural habitat includes sandy substrates (beach) and firm soil (dry forest). We hypothesised that, aside f

Six years after signing the Peace Agreement between the FARC-EP and the Colombian government, the main rural transformations were delayed, while the violence figures show that peace had not materialized. Using an activist methodology, working in the Department of Cauca with rural communities, this article analyses three phases of the ‘territorial peace’ model: the local turn, characterized by the

‘This place becomes a place’ : Artists and placemaking on the margins

Culture and creativity are active but often overlooked processes in contemporary urbanisation. This paper contributes to scholarship on the cultural and creative industries, as well as urban placemaking on the margins, by adopting a placemaking approach in which artists are positioned at the centre of the analysis. The focus is on why artists choose to be located away from national cultural hubs,

Necropolitics, peacebuilding and racialized violence : The elimination of indigenous leaders in Colombia

This paper proposes the concept ‘necropolitics of peacebuilding’ to analyse how contemporary geographies of peace and post-war violence are shaped by the articulation of race, space, politics and the coloniality of power. We explore how post-conflict programmes, plans and policies shape the uneven distribution of life and death, focussing in particular on the elimination of indigenous leaders. Dra
