In this powerful history of the University of Cambridge, Nicolas Bell-Romero considers the nature and extent of Britain's connections to enslavement. His research moves beyond traditional approaches which focus on direct and indirect economic ties to enslavement or on the slave trading hubs of Liverpool and Bristol. From the beginnings of North American colonisation to the end of the American Civil War, the story of Cambridge reveals the vast spectrum of interconnections that university students, alumni, fellows, professors, and benefactors had to Britain's Atlantic slave empire - in dining halls, debating chambers, scientific societies or lobby groups. Following the stories of these middling and elite men as they became influential agents around the empire, Bell-Romero uncovers the extent to which the problem of slavery was an inextricable feature of social, economic, cultural, and intellectual life. This title is also available as open access on Cambridge Core.
Recent research highlights the dynamics of suicide risk, resulting in a shift toward real-time methodologies, such as ecological momentary assessment (EMA), to improve suicide risk identification. However, EMA’s reliance on active self-reporting introduces challenges, including participant burden and reduced response rates during crises. This study explores the potential of Screenomics—a passive digital phenotyping method that captures intensive, real-time smartphone screenshots—to detect suicide risk through text-based analysis.
Method
Seventy-nine participants with past-month suicidal ideation or behavior completed daily EMA prompts and provided smartphone data over 28 days, resulting in approximately 7.5 million screenshots. Text from screenshots was analyzed using a validated dictionary encompassing suicide-related and general risk language.
Results
Results indicated significant associations between passive and active suicidal ideation and suicide planning with specific language patterns. Detection of words related to suicidal thoughts and general risk-related words strongly correlated with self-reported suicide risk, with distinct between- and within-person effects highlighting the dynamic nature of suicide risk factors.
Conclusions
This study demonstrates the feasibility of leveraging smartphone text data for real-time suicide risk detection, offering a scalable, low-burden alternative to traditional methods. Findings suggest that dynamic, individualized monitoring via passive data collection could enhance suicide prevention efforts by enabling timely, tailored interventions. Future research should refine language models and explore diverse populations to extend the generalizability of this innovative approach.
Using National Healthcare Safety Network data, an interrupted time series of intravenous antimicrobial starts (IVAS) among hemodialysis patients was performed. Annual adjusted rates decreased by 6.64% (January 2012–March 2020) and then further decreased by 8.91% until December 2021. IVAS incidence trends have decreased since 2012, including during the early COVID-19 pandemic.
Insights into the paleoneurology and endocranial anatomy of ornithopod dinosaurs come largely from Northern Hemisphere taxa. The recently described non-hadrosaurid iguanodontian Fostoria dhimbangunmal from the Cenomanian of eastern Australia includes a partial skull that offers novel insights into its endocranial anatomy (i.e., the cavity housing the brain). Here, we describe the paleoneurology of F. dhimbangunmal based on a digital cranial endocast obtained from computed tomography. The endocast is mostly complete; however, it is diagenetically dorsoventrally compressed and its ventral limits are not preserved. The endocranial anatomy of F. dhimbangunmal is generally consistent with that of other non-hadrosaurid iguanodontians, including a well-developed olfactory apparatus, suggesting a good sense of smell. In contrast to hadrosaurids and some non-hadrosaurid iguanodontians, F. dhimbangunmal possesses the ancestral flexure condition, in which cranial and pontine flexure angles are subequal. The cerebrum makes up a significant portion of the endocast volume; however, the cerebral hemispheres are not as enlarged or bulbous as seen in hadrosaurids. The forebrain of F. dhimbangunmal did not fill the braincase to the same extent as in hadrosaurids. A distinct vacuity in the supraoccipital of F. dhimbangunmal may represent a new autapomorphy. This study provides the first insights into the neuroanatomy of an Australian iguanodontian dinosaur.
Health technology assessment (HTA) is a critical part of healthcare decision making in many countries. Changes in Methods and Processes (M&P) of HTA agencies can affect the time and degree of patient access to treatments. Published literature focuses on the different M&P adopted by HTA agencies, rather than on how these have come about over time. Our study investigates key HTA reforms and explores their drivers and interdependencies in a set of HTA agencies in Europe, Asia-Pacific, and North America.
Methods
We conducted a targeted literature review on M&P guidelines and subsequent changes to those, for 14 HTA agencies. We supplemented and validated initial findings with 29 semi-structured interviews with country-specific experts. We used analytical tools to create process maps, proactivity and influence networks, and clusters of HTA agencies.
Results
We found that processes leading to M&P reforms follow similar steps across HTA agencies. The three most important drivers to reforms were HTA practice and guidelines in other countries; the healthcare policy, legal, and political context within the agency’s country; and experience of challenges in the assessment by the HTA body itself. International collaborations have the potential to accelerate the evolution of HTA systems and the implementation of reforms.
Conclusion
We identified PBAC (Australia), CDA-AMC (Canada), NICE (England), IQWiG (Germany), and ZIN (the Netherlands) as HTA agencies that are catalysts of HTA reforms as well as internationally influential. International collaborations may represent a useful route to accelerate changes as long as they ensure wide stakeholder engagement at an early stage.
We examined the association between influenza vaccination policies at acute care hospitals and influenza vaccination coverage among healthcare personnel for the 2021–22 influenza season. Mandatory vaccination and masking for unvaccinated personnel were associated with increased odds of vaccination. Hospital employees had higher vaccination coverage than licensed independent practitioners.
To report on the design and results of an innovative nurse practitioner (NP)-led specialist primary care service for children facing housing instability.
Background:
During 2017–2018, children aged 0–14 years represented 23% of the total population receiving support from specialist homeless services in Australia. The impact of housing instability on Australian children is considerable, resulting in disengagement from social institutions including health and education, and poorer physical and mental health outcomes across the lifespan. Current services fail to adequately address health and educational needs of children facing housing insecurity. Research identifies similar circumstances for children in other high-income countries. This paper outlines the design, and reports on results of, an innovative NP-led primary care service for children facing housing instability introduced into three not-for-profit faith-based services in one Australian state.
Methods:
Between 2019 and 2021, 66 children of parents experiencing housing instability received standardized health assessment and referral where appropriate by a NP. Data from the standardized tool, such as condition and severity, were recorded to determine common conditions. In addition, comprehensive case notes recorded by the NP were used to understand potential causes of conditions, and referral needs, including potential barriers.
Findings:
The 66 children assessed were aged between 7 weeks to 16 years. Developmental delay, low immunization rates, and dental caries were the most common conditions identified. Access to appropriate services was inhibited by cost, disengagement, and COVID-19.
Conclusion:
Given their advanced skills and knowledge, embedding NPs in specialist homeless services is advantageous to help vulnerable children.
Birds possess the most diverse assemblage of haemosporidian parasites, although the true diversity is unknown due to high genetic diversity and insufficient sampling across all avian clades. Waterfowl (Order Anseriformes) are an ideal group to discover hidden parasite diversity and examine the role of host ecology in parasite transmission. Waterfowl contain 2 distinct feeding guilds, dabbling and diving, which differ in niche utilization that likely alters vector encounter rates and haemosporidian parasite risk. To determine the role of feeding guild in haemosporidian parasitism we analysed 223 blood samples collected by hunters from the upper Midwest of the United States from 2017 to 2019. Fifty-four individuals were infected by haemosporidian parasites (24·2% prevalence). Infection prevalence differed significantly between dabbling (34·9%, n = 109) and diving (14·0%, n = 114) ducks. Feeding guild was the only host trait that could predict haemosporidian infection risk, with a significantly higher risk in dabbling ducks. Twenty-four haemosporidian lineages were identified, with 9 identified for the first time. Thirteen lineages were found only in dabbling ducks, 5 only in diving ducks and 6 in both feeding guilds. Community analysis showed that each feeding guild harboured a unique parasite community. There was no phylogenetic signal of feeding guild within a phylogenetic reconstruction of North American waterfowl haemosporidian lineages. Our results demonstrate that waterfowl contain a diverse and distinct community of haemosporidian parasites. The unique composition of each feeding guild determines not only haemosporidian infection risk but also community structure. This is the first report of such an impact for waterfowl feeding guilds.
Given the rising trend of politicizing formerly mundane topics, philosophers should guard against the concepts we develop being misunderstood or misconstrued to support arguments we never intended. To demonstrate my assertion, I develop the case study of Alex Kacelnik's notion of “biological rationality” (B-rationality) and show ways in which I believe it is vulnerable to misuse and ways I would suggest re-engineering it to be more resistant. I conclude by urging scholars — especially those working on normatively laden topics — to design our concepts such that they are less likely to become associated with harmful discourse or even oppressive policies.
Identifying feeding interactions in the fossil record remains a key challenge for paleoecologists. We report the rare occurrence of a conical, perforative bite mark in a cervical vertebra of an azhdarchid pterosaur, which we identified as a juvenile individual of Cryodrakon boreas Hone, Habib, and Therrien, 2019 from the Campanian Dinosaur Park Formation in Alberta, Canada. Based on comparative analysis of the dentition and ecomorphology of potential trace makers in the Dinosaur Park Formation, as well as the morphology of the trace, the most likely candidate is a crocodilian, although whether it was made as a result of scavenging or predatory behavior is unknown. Feeding interactions involving pterosaurs are rare globally, whereas crocodilian bite marks are not uncommon in Cretaceous terrestrial ecosystems. Given the opportunistic feeding style and known range of food items for both extant and extinct crocodilians, pterosaurs can be counted as a rare, but not surprising, component of at least some Cretaceous crocodilian diets.
Klebsiella pneumoniae are opportunistic pathogens which can cause mastitis in dairy cattle. K. pneumoniae mastitis often has a poor cure rate and can lead to the development of chronic infection, which has an impact on both health and production. However, there are few studies which aim to fully characterize K. pneumoniae by whole-genome sequencing from bovine mastitis cases. Here, K. pneumoniae isolates associated with mastitis in dairy cattle were identified using matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry (MALDI-TOF MS) and whole-genome sequencing. Furthermore, whole-genome sequence data were used for phylogenetic analyses and both virulence and antimicrobial resistance (AMR) prediction, in parallel with phenotypic AMR testing. Forty-two isolates identified as K. pneumoniae were subject to whole-genome sequencing, with 31 multi-locus sequence types being observed, suggesting the source of these isolates was likely environmental. Isolates were examined for key virulence determinants encoding acquired siderophores, colibactin, and hypermucoidy. The majority of these were absent, except for ybST (encoding yersiniabactin) which was present in six isolates. Across the dataset, there were notable levels of phenotypic AMR against streptomycin (26.2%) and tetracycline (19%), and intermediate susceptibility to cephalexin (26.2%) and neomycin (21.4%). Of importance was the detection of two ESBL-producing isolates, which demonstrated multi-drug resistance to amoxicillin-clavulanic acid, streptomycin, tetracycline, cefotaxime, cephalexin, and cefquinome.
In the last decades, research from cognitive science, clinical psychology, psychiatry, and social neuroscience has provided mounting evidence that several social cognitive abilities are impaired in people with schizophrenia and contribute to functional difficulties and poor clinical outcomes. Social dysfunction is a hallmark of the illness, and yet, social cognition is seldom assessed in clinical practice or targeted for treatment. In this article, 17 international experts, from three different continents and six countries with expertise in social cognition and social neuroscience in schizophrenia, convened several meetings to provide clinicians with a summary of the most recent international research on social cognition evaluation and treatment in schizophrenia, and to lay out primary recommendations and procedures that can be integrated into their practice. Given that many extant measures used to assess social cognition have been developed in North America or Western Europe, this article is also a call for researchers and clinicians to validate instruments internationally and we provide preliminary guidance for the adaptation and use of social cognitive measures in clinical and research evaluations internationally. This effort will assist promoting scientific rigor, enhanced clinical practice, and will help propel international scientific research and collaboration and patient care.
Advance care planning (ACP) supports communication and medical decision-making and is best conceptualized as part of the care planning continuum. Black older adults have lower ACP engagement and poorer quality of care in serious illness. Surrogates are essential to effective ACP but are rarely integrated in care planning. Our objective was to describe readiness, barriers, and facilitators of ACP among seriously ill Black older adults and their surrogates.
Methods
We used an explanatory sequential mixed methods study design. The setting was 2 ambulatory specialty clinics of an academic medical center and 1 community church in Northern California, USA. Participants included older adults and surrogates. Older adults were aged 60+, self-identified as Black, and had received care at 1 of the 2 clinics or were a member of the church congregation. Surrogates were aged 18+ and could potentially make medical decisions for the older adult. The validated ACP engagement survey was used to assess confidence and readiness for ACP. What “matters most” and barriers and facilitators to ACP employed questions from established ACP materials and trials. Semi-structured interviews were conducted after surveys to further explain survey results.
Results
Older adults (N = 30) and surrogates (N = 12) were confident that they could engage in ACP (4.1 and 4.7 out of 5), but many were not ready for these conversations (3.1 and 3.9 out of 5). A framework with 4 themes – illness experience, social connections, interaction with health providers, burden – supports identification of barriers and facilitators to ACP engagement.
Significance of results
We identified barriers and facilitators and present a framework to support ACP engagement. Future research can assess the impact of this framework on communication and decision-making.
The efficacy and safety of aripiprazole once-monthly 400 mg (AOM 400) as maintenance monotherapy treatment for bipolar I disorder (BP-I) were demonstrated in a double-blind, placebo-controlled, 52-week randomized withdrawal trial (NCT01567527). This post hoc analysis of data from NCT01567527 evaluated the efficacy of AOM 400 in the earlier BP-I population.
Methods
Patients within the first quartile of the dataset according to age (18–32 years: AOM 400, n=36; placebo, n=34) or disease duration (≤4.6 years: AOM 400, n=33; placebo, n=34) were considered to be in the earlier stages of BP-I, and were included. The primary outcome was time from randomization to recurrence of any mood episode, defined as meeting any one of several predetermined criteria, including Young Mania Rating Scale (YMRS) total score ≥15 or clinical worsening.
Results
Time to recurrence of any mood episode was significantly delayed with AOM 400 versus placebo in patients aged 18–32 years (hazard ratio [HR]: 2.462 [95% confidence interval (CI): 1.092, 5.547]; p<0.05) and in patients with a disease duration ≤4.6 years (HR: 3.207 [95% CI: 1.346, 7.645]; p<0.01). Further analysis suggested that the benefit of AOM 400 versus placebo was driven by a significantly lower proportion of patients experiencing a YMRS total score ≥15 (18–32 years: 5.60% versus 44.10%, p<0.001; disease duration ≤4.6 years: 6.10% versus 41.20%, p<0.01) or clinical worsening (18–32 years: 8.30% versus 38.20%, p<0.01; disease duration ≤4.6 years: 6.10% versus 38.20%, p<0.01).
Conclusion
The efficacy of AOM 400 was demonstrated in the earlier BP-I population.

Pemetrexed and immunotherapies (e.g., pembrolizumab) are approved for first-line maintenance (1LM) treatment of nonsquamous advanced/metastatic non-small-cell lung cancer (NSCLC), but real-world data on their use are limited. The objective of this study was to assess 1LM clinical outcomes, safety, and treatment patterns of immunotherapy versus immunotherapy+pemetrexed among patients with advanced/metastatic NSCLC from the EU4 (France, Germany, Italy, Spain)+UK.
Methods
Data from patients in the US, Canada, and EU4+UK with nonsquamous advanced/metastatic NSCLC without targetable mutations were collected via electronic case report form. Physician-identified patients (≥18 y) in the EU4+UK were eligible for this subgroup analysis if they achieved stable disease or complete or partial response with first-line platinum-based chemotherapy+immunotherapy (January 2019 to March 2021) and received 1LM immunotherapy or immunotherapy+pemetrexed. Patients were followed from index (1LM initiation) until last physician contact or death. Outcomes were overall survival (OS), progression-free survival (PFS), treatment patterns and duration, and adverse events.
Results
Among the selected 367 patients (male, 71.9%; mean±StDev age, 63.4±7.2 y; current/former smokers, 85.8%), 203 (55.3%) received immunotherapies, most commonly pembrolizumab (n=173; 85.2%), and 164 (44.7%) received immunotherapy+pemetrexed. Patients receiving immunotherapy had longer median adjusted OS and PFS compared to those receiving immunotherapy+pemetrexed (OS hazard ratio [HR]: 0.63; 95% confidence interval [CI]: 0.36, 0.90; PFS HR: 0.58; 95% CI: 0.38, 0.79). Patients receiving immunotherapy versus patients receiving immunotherapy+pemetrexed had longer median treatment duration (14.0 vs 10.3 mo; p<0.001) and were less likely to experience anemia (19.7% vs 33.5%; p<0.01). Results were similar in the overall study population.
Conclusions
In this real-world study, among the selected patients with nonsquamous advanced/metastatic NSCLC who achieved stable disease or complete or partial response with first-line therapy, the addition of pemetrexed to immunotherapy in 1LM did not appear to confer a clinical benefit. Identifying treatments that can improve clinical outcomes for these patients remains an area of unmet need.
