Was the British empire given away in a fit of collective indifference as many have claimed? Englishness and Empire looks at connections between stories of nation and empire told in the media - the Second World War, the Coronation and Everest, colonial wars of the 1950s, immigration, Winston Churchill's funeral - and makes an important and origi.

Burkholderia pseudomallei, the etiologic agent of melioidosis, is a Gram negative bacterium designated as a Tier 1 threat. This bacterium is known to be endemic in Southeast Asia and Northern Australia and can infect humans and animals by several routes. Inhalational melioidosis has been associated with monsoonal rains in endemic areas and is also a significant concern in the biodefense community. There are currently no effective vaccines for B. pseudomallei and antibiotic treatment can be hampered by non-specific symptomology and also the high rate of naturally occurring antibiotic resistant strains. Well-characterized animal models will be essential when selecting novel medical countermeasures for evaluation prior to human clinical trials. Here, we further characterize differences between the responses of BALB/c and C57BL/6 mice when challenged with low doses of a low-passage and well-defined stock of B. pseudomallei K96243 via either intraperitoneal or aerosol routes of exposure. Before challenge, mice were implanted with a transponder to collect body temperature readings, and daily body weights were also recorded. Mice were euthanized on select days for pathological analyses and determination of the bacterial burden in selected tissues (blood, lungs, liver, and spleen). Additionally, spleen homogenate and sera samples were analyzed to better characterize the host immune response after infection with aerosolized bacteria. These clinical, pathological, and immunological data highlighted and confirmed important similarities and differences between these murine models and exposure routes.

Several different human vaccines are available to protect against anthrax. We compared the human adaptive immune responses generated by three different anthrax vaccines or by previous exposure to cutaneous anthrax. Adaptive immunity was measured by ELISPOT to count cells that produce interferon (IFN)-γ in response to restimulation ex vivo with the anthrax toxin components PA, LF and EF and by measuring circulating IgG specific to these antigens. Neutralising activity of antisera against anthrax toxin was also assayed. We found that the different exposures to anthrax antigens promoted varying immune responses. Cutaneous anthrax promoted strong IFN-γ responses to all three antigens and antibody responses to PA and LF. The American AVA and Russian LAAV vaccines induced antibody responses to PA only. The British AVP vaccine produced IFN-γ responses to EF and antibody responses to all three antigens. Anti-PA (in AVA and LAAV vaccinees) or anti-LF (in AVP vaccinees) antibody titres correlated with toxin neutralisation activities. Our study is the first to compare all three vaccines in humans and show the diversity of responses against anthrax antigens.

This piece follows Stuart Ward's Untied Kingdom as it traverses a collapsing British Empire and an increasingly disunited United Kingdom to tell the complex history of Britishness in retreat across the world, mainly between 1945 and the early twenty-first century. It reviews some of the shifting meanings of Britishness that Ward charts in different contexts, different territories and at different moments in this history and the dwindling resonance of Britishness almost everywhere. It reviews other main themes that thread through the book: language, migration, race, belonging and unbelonging, nationalism, violence, and the impact of imperialism and colonialism on cultures, societies and mindsets.

Hospitals ceased most elective procedures during the height of coronavirus disease 2019 (COVID-19) infections. As hospitals begin to recommence elective procedures, it is necessary to have a means to assess how resource intensive a given case may be. To evaluate the development and performance of a clinical decision support tool to inform resource utilization for elective procedures. In this prognostic study, predictive modeling was used on retrospective electronic health records data from a large academic health system comprising 1 tertiary care hospital and 2 community hospitals of patients undergoing scheduled elective procedures from January 1, 2017, to March 1, 2020. Electronic health records data on case type, patient demographic characteristics, service utilization history, comorbidities, and medications were and abstracted and analyzed. Data were analyzed from April to June 2020. Predicitons of hospital length of stay, intensive care unit length of stay, need for mechanical ventilation, and need to be discharged to a skilled nursing facility. These predictions were generated using the random forests algorithm. Predicted probabilities were turned into risk classifications designed to give assessments of resource utilization risk. Data from the electronic health records of 42 199 patients from 3 hospitals were abstracted for analysis. The median length of stay was 2.3 days (range, 1.3-4.2 days), 6416 patients (15.2%) were admitted to the intensive care unit, 1624 (3.8%) received mechanical ventilation, and 2843 (6.7%) were discharged to a skilled nursing facility. Predictive performance was strong with an area under the receiver operator characteristic ranging from 0.76 to 0.93. Sensitivity of the high-risk and medium-risk groupings was set at 95%. The negative predictive value of the low-risk grouping was 99%. We integrated the models into a daily refreshing Tableau dashboard to guide decision-making. The clinical decision support tool is currently being used by surgical leadership to inform case scheduling. This work shows the importance of a learning health care environment in surgical care, using quantitative modeling to guide decision-making.

Background. Postexposure prophylaxis of inhalational anthrax requires prolonged antibiotic therapy or antibiotics and vaccination. The duration of treatment for established anthrax is controversial, because retained spores may germinate and cause disease after antibiotics are discontinued. Using rhesus macaques, we determined whether a short course of antibiotic treatment, as opposed to prophylaxis, could effectively treat inhalational anthrax and prevent disease caused by the germination of spores after discontinuation of antibiotics. Methods. Two groups of 10 rhesus macaques were exposed to an aerosol dose of Bacillus anthracis spores. Animals in group 1 received ciprofloxacin prophylaxis beginning 1–2 h after exposure. Those in group 2 began receiving ciprofloxacin after becoming bacteremic, and treatment was continued for 10 days. When each group 2 animal completed 10 days of therapy, the prophylactic antibiotic was discontinued in the paired group 1 animal. Results. In group 1 (prophylaxis), no deaths occurred during antibiotic treatment, but only 2 (20%) of 10 animals survived after antibiotics were discontinued. In contrast, in group 2 (treatment), 3 deaths occurred during antibiotic treatment, but all 7 animals (100%) alive after 10 days of therapy survived when antibiotics were discontinued. Conclusions. In the treatment of inhalational anthrax, the prolonged course of antibiotics required to achieve prophylaxis may not be necessary to prevent anthrax that results from the germination of retained spores after the discontinuation of antibiotics.

This essay considers the potential of histories of transnational movements of people, and the erosion of boundaries between British domestic and imperial history, to expand and revise the history of nineteenth- and twentieth-century British domestic life and work. Literatures on migration demonstrate how far the history of home involves transnational themes, including the recruitment of migrants and refugees who crossed national borders to do domestic work--in Britain and empire--and their development of what has been called the 'transnational family'. Domestic life, including motherhood, cannot be fully understood outside the history of the control and orchestration of national borders: which people were allowed inside for settlement, which people were refused entry, which people were positively encouraged to enter. The essay considers refugee movements as part of transnational movements--a neglected area in historical work, including work on Britain--developing a case study that compares the recruitment of people from displaced persons camps to the Australian and British labour markets in the late 1940s, situating both recruitment schemes in the context of post-war British migration to Australia.

BackgroundTransparency around surgeon level data may align healthcare delivery with quality care for patients. Biliary surgery includes numerous procedures performed by both general surgeons and subspecialists alike. Cholecystectomy is a common surgical procedure and an optimal cohort to measure quality outcomes within a healthcare system.MethodsData were collected for 5084 biliary operations performed by 68 surgeons in 11 surgical divisions in a health system including a tertiary academic hospital, two regional community hospitals, and two ambulatory surgery centers. A privacy protected dashboard was developed to compare surgeon performance and cost between July 2018 and June 2022. A sample cohort of patients ≥ 18 years who underwent cholecystectomy were compared by operative time, cost, and 30-day outcomes.ResultsOver 4 years, 4568 cholecystectomy procedures were performed by 57 surgeons. Operations were done by 57 surgeons in four divisions and included 3846 (84.2%) laparoscopic cholecystectomies, 601 (13.2%) laparoscopic cholecystectomies with cholangiogram, and 121 (2.6%) open cholecystectomies. Patients were admitted from the emergency room in 2179 (47.7%) cases while 2389 (52.3%) cases were performed in the ambulatory setting. Individual surgeons were compared to peers for volume, intraoperative data, cost, and outcomes. Cost was lowest at ambulatory surgery centers, yet only 4.2% of elective procedures were performed at these facilities. Prepackaged kits with indocyanine green were more expensive than cholangiograms that used iodinated contrast. The rate of emergency department visits was lowest when cases were performed at ambulatory surgery centers.ConclusionData generated from clinical dashboards can inform surgeons as to how they compare to peers regarding quality metrics such as cost, time, and complications. In turn, this may guide strategies to standardize care, optimize efficiency, provide cost savings, and improve outcomes for cholecystectomy procedures. Future application of clinical dashboards can assist surgeons and administrators to define value-based care.
