Abstract
INTRODUCTION ChatGPT, a sophisticated large language model (LLM), has garnered widespread attention for its ability to mimic human-like communication. As recent studies indicate a potential supportive role of ChatGPT in academic writing, we assessed the LLM's capacity to generate accurate and comprehensive scientific abstracts from published Randomised Controlled Trial (RCT) data, focusing on the adherence to the Consolidated Standards of Reporting Trials for Abstracts (CONSORT-A) statement, in comparison to the original authors' abstracts. METHODOLOGY RCTs, identified in a PubMed/MEDLINE search post-September 2021 across various medical disciplines, were subjected to abstract generation via ChatGPT versions 3.5 and 4, following the guidelines of the respective journals. The overall quality score (OQS) of each abstract was determined by the total number of adequately reported components from the 18-item CONSORT-A checklist. Additional outcome measures included percent adherence to each CONOSORT-A item, readability, hallucination rate, and regression analysis of reporting quality determinants. RESULTS Original abstracts achieved a mean OQS of 11.89 (95% CI: 11.23-12.54), outperforming GPT 3.5 (7.89; 95% CI: 7.32-8.46) and GPT 4 (5.18; 95% CI: 4.64-5.71). Compared to GPT 3.5 and 4 outputs, original abstracts were more adherent with 10 and 14 CONSORT-A items, respectively. In blind assessments, GPT 3.5-generated abstracts were deemed most readable in 62.22% of cases which was significantly greater than the original (31.11%; P = 0.003) and GPT 4-generated (6.67%; P<0.001) abstracts. Moreover, ChatGPT 3.5 exhibited a hallucination rate of 0.03 items per abstract compared to 1.13 by GPT 4. No determinants for improved reporting quality were identified for GPT-generated abstracts. CONCLUSIONS While ChatGPT could generate more readable abstracts, their overall quality was inferior to the original abstracts. Yet, its proficiency to concisely relay key information with minimal error holds promise for medical research and warrants further investigations to fully ascertain the LLM's applicability in this domain.

Abstract
OBJECTIVES To describe the clinical signs and outcome of a large cohort of dogs presenting with neurological signs secondary to Neospora caninum infection. MATERIALS AND METHODS Retrospective review of cases presenting to two UK referral centres with neurological signs secondary to N. caninum infection between 2014 and 2023. Presenting signs, diagnostic test results, treatment, short- and long-term outcome analysed. RESULTS A total of 1690 cases were assessed for eligibility. Forty-four cases with a diagnosis of neosporosis were obtained. Three cases were then excluded due to non-neurological presentations (two hepatitis and one myocarditis). A total of 41 cases were included in the study. Cerebello-vestibular signs predominated; however, presenting clinical signs were varied and the neurolocalisation was often multifocal in nature (46.3%), making neosporosis an important differential diagnosis for meningoencephalitis of unknown origin. Complete clinical improvement was rare (5.6%), and relapses were common (27.8% cases with follow-up). CLINICAL SIGNIFICANCE Neosporosis remains an important differential diagnosis for dogs at any age presenting with multifocal neurological signs. The outcome is considered poor and relapse rate is high.

Abstract
BACKGROUND Visceral obesity, a strong indicator of chronic inflammation and impaired metabolic health, has been shown to be associated with poor postoperative outcomes and complications. This study aimed to evaluate the relationship between visceral fat area (VFA) and periprosthetic joint infection (PJI) in total joint arthroplasty (TJA) patients. METHODS A retrospective study of 484 patients who had undergone a total hip or knee arthroplasty was performed. All patients had a computed tomography scan of the abdomen/pelvis within two years of their TJA. Body composition data (ie, VFA, subcutaneous fat area, and skeletal muscle area) were calculated at the Lumbar-3 vertebral level via two fully automated and externally validated machine learning algorithms. A multivariable logistic model was created to determine the relationship between VFA and PJI, while accounting for other PJI risk factors. Of the 484 patients, 31 (6.4%) had a PJI complication. RESULTS The rate of PJI among patients with VFA in the top quartile (> 264.1 cm2) versus bottom quartile (< 82.6 cm2) was 5.6% versus 10.6% and 18.8% versus 2.7% in the total hip arthroplasty and total knee arthroplasty cohorts, respectively. In the multivariate model, total knee arthroplasty patients with a VFA in the top quartile had a 30.5 times greater risk of PJI than those in the bottom quartile of VFA (P = .0154). CONCLUSION VFA may have a strong association with PJI in TJA patients. Using a standardized imaging modality like computed tomography scans to calculate VFA can be a valuable tool for surgeons when assessing risk of PJI.

Abstract
Omicron variants of SARS-CoV-2 are globally dominant and infection rates are very high in children. We measure immune responses following Omicron BA.1/2 infection in children aged 6-14 years and relate this to prior and subsequent SARS-CoV-2 infection or vaccination. Primary Omicron infection elicits a weak antibody response with poor functional neutralizing antibodies. Subsequent Omicron reinfection or COVID-19 vaccination elicits increased antibody titres with broad neutralisation of Omicron subvariants. Prior pre-Omicron SARS-CoV-2 virus infection or vaccination primes for robust antibody responses following Omicron infection but these remain primarily focussed against ancestral variants. Primary Omicron infection thus elicits a weak antibody response in children which is boosted after reinfection or vaccination. Cellular responses are robust and broadly equivalent in all groups, providing protection against severe disease irrespective of SARS-CoV-2 variant. Immunological imprinting is likely to act as an important determinant of long-term humoral immunity, the future clinical importance of which is unknown.

Abstract
Changes in old age that contribute to the complex issue of an increased metabolic cost of walking (mass-specific energy cost per unit distance traveled) in older adults appear to center at least in part on changes in gait biomechanics. However, age-related changes in energy metabolism, neuromuscular function and connective tissue properties also likely contribute to this problem, of which the consequences are poor mobility and increased risk of inactivity-related disease and disability. The U.S. National Institute on Aging convened a workshop in September 2021 with an interdisciplinary group of scientists to address the gaps in research related to the mechanisms and consequences of changes in mobility in old age. The goal of the workshop was to identify promising ways to move the field forward toward improving gait performance, decreasing energy cost, and enhancing mobility for older adults. This report summarizes the workshop and brings multidisciplinary insight into the known and potential causes and consequences of age-related changes in gait biomechanics. We highlight how gait mechanics and energy cost change with aging, the potential neuromuscular mechanisms and role of connective tissue in these changes, and cutting-edge interventions and technologies that may be used to measure and improve gait and mobility in older adults. Key gaps in the literature that warrant targeted research in the future are identified and discussed.

Abstract
BACKGROUND Postpartum hemorrhage (PPH) may be exacerbated by hemostatic impairment. Information about PPH-associated coagulopathy is limited, often resulting in treatment strategies based on data derived from trauma studies. OBJECTIVES To investigate hemostatic changes associated with PPH. PATIENTS/METHODS From a population of 11 279 maternities, 518 (4.6%) women were recruited with PPH ≥ 1000 mL or placental abruption, amniotic fluid embolism, or concealed bleeding. Routine coagulation and viscoelastometric results were collated. Stored plasma samples were used to investigate women with bleeds > 2000 mL or those at increased risk of coagulopathy defined as placenta abruption, amniotic fluid embolism, or need for blood components. Procoagulant factors were assayed and global hemostasis was assessed using thrombin generation. Fibrinolysis was investigated with D-dimer and plasmin/antiplasmin complexes. Dysfibrinogenemia was assessed using the Clauss/antigen ratio. RESULTS At 1000 mL blood loss, Clauss fibrinogen was ≤2 g/L in 2.4% of women and 6/27 (22.2%) cases of abruption. Women with very large bleeds (>3000 mL) had evidence of a dilutional coagulopathy, although hemostatic impairment was uncommon. A subgroup of 12 women (1.06/1000 maternities) had a distinct coagulopathy characterized by massive fibrinolysis (plasmin/antiplasmin > 40 000 ng/mL), increased D-dimer, hypofibrinogenemia, dysfibrinogenemia, reduced factor V and factor VIII, and increased activated protein C, termed acute obstetric coagulopathy. It was associated with fetal or neonatal death in 50% of cases and increased maternal morbidity. CONCLUSIONS Clinically significant hemostatic impairment is uncommon during PPH, but a subgroup of women have a distinct and severe coagulopathy characterized by hyperfibrinolysis, low fibrinogen, and dysfibrinogenemia associated with poor fetal outcomes.

Abstract
There are unique, enduring challenges related to mathematics instruction in urban schools, and the most common concerns are related to issues of equitable access to mathematics learning opportunities. In this editorial, we argue that the complexity of teaching mathematics in urban schools requires the attention of mathematics scholars with unique training, expertise, and experiences. Developing mathematics instruction for urban spaces often involves refined research techniques, multi-disciplinary perspectives, and collaboration between diverse stakeholders. Specificity is the key to addressing these challenges. However, to date, the Journal of Urban Mathematics Education (JUME)—out of 69 mathematics education-focused journals (Nivens & Otten, 2017)—is the only journal venue devoted to mathematics teaching and learning in urban environments. Although other mathematics education journals and conferences accept scholarship related to urban schools, due to the vast nature of mathematics education research and limitations in journal space, the nuances of specific issues in urban mathematics education (e.g., preparing mathematics teachers well for high-needs urban schools) are underexamined and poorly understood.

Abstract
Importance More than 70% of Medicare beneficiaries in Puerto Rico are enrolled in a Medicare Advantage (MA) plan. Evidence of MA plan payments and quality in Puerto Rico compared with the 50 US states and Washington, DC (hereafter referred to as US mainland), is lacking, notably after implementation of the Patient Protection and Affordable Care Act (ACA). Objective To compare MA plan payments and quality in Puerto Rico with those in the US mainland and to evaluate how differences between MA plans in Puerto Rico and the US mainland changed after ACA implementation. Design, Setting, and Participants This cohort study used publicly available data on MA plans from January 1, 2006, to December 31, 2019, from the Centers for Medicare & Medicaid Services. Data analysis was performed from October 2019 to February 2022. Exposures Medicare Advantage plans in Puerto Rico and implementation of the ACA. Main Outcomes and Measures Primary outcomes were risk-standardized federal benchmark payments (the amount offered by the federal government for insuring a beneficiary of average risk), risk-standardized plan bids (a plan's asking price for a beneficiary of average risk), and rebates received by plans. Additional outcomes included risk-adjusted benchmarks, risk-adjusted bids, actual plan payment, and aggregate plan quality ratings (star ratings). A difference-in-differences analysis examined differential changes in plan payments in Puerto Rico vs the US mainland after ACA implementation. Results Before ACA implementation, 211 MA plans in Puerto Rico and 13 899 plans in the US mainland were included. After ACA implementation, 433 MA plans in Puerto Rico and 29 515 plans in the US mainland were included. Before ACA implementation, risk-standardized benchmarks were 33% lower for MA plans in Puerto Rico than plans in the US mainland ($556.73 [95% CI, $551.82-$561.64] vs $831.15 [95% CI, $828.55-$833.75] per beneficiary per month [PBPM]). This gap increased to 38% after ACA implementation ($540.58 [95% CI, $536.86-$544.32] vs $869.31 [95% CI, $868.21-$870.42] PBPM). Risk-standardized plan bids in Puerto Rico were 46% lower before ACA implementation and 43% lower after ACA implementation compared with those in the US mainland. Rebates in Puerto Rico decreased from $168.50 (95% CI, $163.57-$173.42) PBPM before ACA implementation to $93.39 (95% CI, $89.51-$97.27) PBPM after ACA implementation, a decrease of $75.11 PMPM compared with a decrease of $2.05 PMPM in the US mainland. Plans in Puerto Rico received increased quality bonus payments, and the mean (SD) risk score for plans in Puerto Rico increased to 1.55 (0.31) after ACA implementation, which increased risk-adjusted benchmarks and actual plan payments, offsetting the widening payment disparity. Conclusions and Relevance This cohort study found that after implementation of the ACA, federal benchmark payment amounts decreased in Puerto Rico compared with the US mainland. Responses by MA plans in Puerto Rico, including increased quality bonus payments and risk scores, offset this payment reduction, although actual plan payments in Puerto Rico were lower than those in the US mainland.

Abstract
6551 Background: Targeted therapies are important first-line treatments for many patients with non-small cell lung cancer (NSCLC) and colorectal cancer (CRC). All patients with newly-diagnosed metastatic NSCLC and CRC should undergo molecular diagnostic testing to guide treatment selection. Methods: We used 100% Medicare fee-for-service data from 2015 through 2019 to identify beneficiaries with incident metastatic NSCLC or CRC receiving systemic therapy and to assign beneficiaries to oncology practices. We then assessed for use of molecular diagnostic testing and targeted therapies in these cohorts. We used linear mixed effects models to assess patient and practice characteristics associated with molecular diagnostic testing and targeted therapy use. Results: Rates of molecular diagnostic testing increased between 2015 and 2019 for NSCLC and CRC. In 2019, rates of molecular diagnostic testing were 85% and 65% for NSCLC and CRC, respectively. Rates of targeted therapy use did not increase over time for NSCLC or CRC, and were 8% and 5%, respectively, in 2019. Compared to National Cancer Institute (NCI)-designated cancer centers, rates of molecular diagnostic testing for CRC were 3.7 percentage points lower at practices associated with non-academic hospitals and 10.6 percentage points lower at small independent practices. Rates of targeted therapy use for NSCLC were 4.8, 5.9 and 5.5 percentage points lower at academic medical centers, large independent practices and small independent practices, respectively, compared to NCI centers. Conclusions: Rates of molecular diagnostic testing for NSCLC and CRC increased in recent years, but testing rates remain below recommended levels, and targeted therapy use remains low. Substantial variation in testing and targeted therapy use by practice type suggest that the practice where a patient is treated may impact access to recommended testing and efficacious treatments.

Abstract
Aims/Objectives/BackgroundE-scooters have risen in popularity worldwide. However, e-scooter associated injuries have become a growing area of concern. In the UK, rental e-scooters became legalised in 2020, and have been rolled out in several UK cities. There is no published UK literature reporting e-scooter related injuries. This service evaluation aims to evaluate the impact of e-scooters on Emergency Departments (ED) within one UK city.Methods/DesignBetween May to June 2021, we conducted an approved (CE:74681) prospective observational service evaluation for a 4-week period across three EDs; one Adult Major Trauma centre (MTC), one city-centre Trauma Unit and one Paediatric MTC. All patients presenting to ED with an injury associated with an e-scooter (driver, passenger or bystander) were identified prospectively. Data collected included information on context of injury event and key clinical variables. Data was entered onto the online platform REDCap, and exported into Excel for analysis. Descriptive statistics are presented.Results/ConclusionsNinety patients with an e-scooter related injury presented to ED during the evaluation. Median age was 25 years (IQR, 20-33). Findings demonstrate head, upper limbs and lower limbs were commonly injured. Of the 19% who experienced a head injury, two patients sustained an intracranial haemorrhage and one a basal skull fracture. Fractures were diagnosed in 41% of patients. Only 7% of riders were helmeted and 28% were intoxicated with alcohol. In total 62 x-rays and 13 CTs were undertaken. Although the majority were discharged following minor injuries, 11% of patients required admission, including one major trauma.Whilst e-scooters are a convenient mode of transport, riders are vulnerable to traumatic injuries of varying severity. Notably, low rates of helmet use and high prevalence of alcohol intoxication, suggest a need for targeted public health interventions. Future large-scale research is required to better evidence injury patterns and severity, identify modifiable risk factors and inform policy.

Abstract
Aims: Social prescribing continues to grow and change across healthcare services in
Wales; however, research of the day-to-day performance of social prescribers
is limited. This study aimed to explore which roles are perceived to be the
most important and frequently used by social prescribers in Wales and
compare these results to reports in studies of services in other countries
in order to support future role development and potential
standardisation. Methods: This study used the Group Concept Mapping via the Concept Systems Global Max™
software to collect and analyse all data from both participants and
literature. Results: There was a total of 101 statements generated (119 participants, 84
literature) ranging from generic interpersonal skills to specialised
training (cognitive behavioural therapy). These statements were then sorted
by conceptual similarity into seven clusters (Providing a Specialist
Service, Working in a person-centred way, Skills, Connecting Clients with
Community, Collaborative Working, Evaluating and postprogramme duties, and
Networking/Community). Statements were rated based on their perceived
importance and frequency, with the ‘Skills’ cluster having the highest
overall average and ‘Providing a Specialist Service’ having the lowest. Conclusions: Reports indicate that in general there is variation in the roles performed by
individual participants in Wales; however, greater variation was observed
between participants and literature suggesting geographical divergence in
practice. In the top 12 highest rated statements for both frequency and
importance, individualistic traits such as empathy and ‘being a listener’
are favoured over specialised methods such as cognitive behavioural therapy
and behaviour change taxonomy. Results suggest that local need plays a part
in the choices and performance of social prescribers and as such should be
considered in future standardisation.

Abstract
Loss of the tumor suppressor gene Pten in murine prostate recapitulates human carcinogenesis and causes stromal proliferation surrounding murine prostate intraepithelial neoplasia (mPIN), which is reactive to microinvasion. In turn, invasion has been shown to be regulated in part by de novo fatty acid synthesis in prostate cancer. We therefore investigated the effects of genetic ablation of Fasn on invasive potential in prostate‐specific Pten knockout mice. Combined genetic ablation of Fasn and Pten reduced the weight and volume of all the prostate lobes when compared to single knockouts. The stromal reaction to microinvasion and the cell proliferation that typically occurs in Pten knockout were largely abolished by Fasn knockout. To verify that Fasn knockout indeed results in decreased invasive potential, we show that genetic ablation and pharmacologic inhibition of FASN in prostate cancer cells significantly inhibit cellular motility and invasion. Finally, combined loss of PTEN with FASN overexpression was associated with lethality as assessed in 660 prostate cancer patients with 14.2 years of median follow‐up. Taken together, these findings show that de novo lipogenesis contributes to the aggressive phenotype induced by Pten loss in murine prostate and targeting Fasn may reduce the invasive potential of prostate cancer driven by Pten loss. © 2020 The Authors.

Abstract
Treatment with T-cells redirected to tumour specificity with a chimeric antigen receptor (CAR) may be well suited to treat intracranial tumours due to the ability of T-cells to access the central nervous system and migrate to infiltrative sites of disease. In adult glioblastoma, a case report of local and distant eradication of intracranial and spinal tumour deposits following intraventricular infusion of IL13Ra2-CAR T-cells indicates the potential of this approach. However, in contrast to the sustained complete remissions observed in haematological malignancies, in the majority of patients with glioblastoma CAR T-cell therapy has not resulted in clinical benefit. Tumour heterogeneity and the highly immune inhibitory tumour microenvironment (TME) are likely key barriers to achieving durable anti-tumour immunity. Here use intra-tumoural administration of IL-12 to enable CAR T-cell immunity. We employed CAR-T cells targeting the tumour-specific epidermal growth factor variant III (EGFRvIII). In an immunocompetent orthotopic mouse model of high-grade glioma, we show that CAR-T cells alone failed to control fully established tumour, but when combined with a single, locally delivered dose of IL-12, durable antitumor responses were achieved. IL-12 not only boosted cytotoxicity of CAR T-cells, but also reshaped the TME driving increased infiltration of proinflammatory CD4+ T-cells, decreased numbers of regulatory T-cells (Tregs) and activation of the myeloid compartment. Critically, immunotherapy enabling benefits of IL-12 were achieved with minimal systemic effects. Our findings show that local delivery of IL-12 is an effective adjuvant for CAR-T cell therapy for high-grade glioma. Assessment of application in high-risk childhood brain tumours is ongoing.

Abstract
Abstract
The Class IA PI3 kinase isoforms (p110α, β, and δ) transduce many growth factor signals that are important for the proliferation, differentiation, and self-renewal of hematopoietic stem cells (HSCs). Mutations in growth factor receptors or RAS proteins are commonly observed in patients with acute myeloid leukemia (AML), leading to activation of the PI3K/AKT pathway. Therefore, PI3K inhibition is an attractive therapeutic strategy for a large subset of AML patients. We previously reported that p110α is dispensable for HSC function, suggesting that redundancy exists between the Class IA isoforms in HSCs (Gritsman et al., J Clin Invest 2014). However, we have identified a specific role for p110α in RAS-mutated myeloid leukemia. Furthermore, we found that the p110α-selective inhibitor BYL-719 can sensitize RAS-mutated leukemic cells to the MEK inhibitor MEK-162. While PI3K inhibitors have multiple clinical indications, including in hematologic malignancies, it is still unclear whether PI3K plays an important role in normal HSC function. Upon environmental stresses like chemotherapy or infection, quiescent HSCs must enter the cell cycle to re-establish homeostasis and promote emergency myelopoiesis. To test for redundancy between p110α and p110δ in HSCs, we generated p110α and p110δ double knockout (DKO) mice, with germline deletion of p110δ and conditional deletion of p110α. DKO mice have leukopenia, anemia, and decreased numbers of lymphoid-primed multipotent progenitors (LMPPs) in the bone marrow, though HSC numbers are unchanged. In competitive repopulation assays, B-cell maintenance was severely impaired, while the myeloid and T-cell lineages were relatively preserved. This suggests that HSC function is not impaired at steady state. We performed transcriptome analysis of DKO, p110δ, and p110α KO HSCs and LMPPs after bone marrow transplantation. Gene set enrichment analysis revealed downregulation of gene sets associated with cell cycle progression. Interestingly, we also observed negative enrichment of inflammatory response gene sets in both p110δ KO and DKO HSCs and LMPPs. To examine the roles of p110δ and α in the hematopoietic stress response, we injected p110δ, DKO, and WT mice with 5-fluorouracil. We observed significantly decreased survival of 5-FU-treated DKO mice due to impaired hematopoietic recovery, associated with the failure of HSCs to enter the cell cycle. Consistent with this finding, we also observed a decrease in myeloid reconstitution by DKO HSCs in secondary competitive transplantation, suggesting that p110α and p110δ play redundant roles in emergency myelopoiesis. We also observed defects in downstream signaling in DKO HSCs and progenitors in response to IL1β or TNFα stimulation. Our results suggest that p110α and δ act in a redundant fashion to transduce specific inflammatory signals in HSPCs in response to hematopoietic stress. Our results have important implications for the use of PI3K inhibitors in combination with chemotherapy and in other hematopoietic stress conditions.

Abstract
INTRODUCTION To combine numerical simulations, in vitro and in vivo experiments to evaluate the feasibility of measuring diffusion exchange across the cell membrane with diffusion exchange spectroscopy (DEXSY). METHODS DEXSY acquisitions were simulated over a range of permeabilities in nerve tissue and yeast substrates. In vitro measurements were performed in a yeast substrate and in vivo measurements in mouse tumor xenograft models, all at 9.4 T. RESULTS Diffusion exchange was observed in simulations over a physiologically relevant range of cell permeability values. In vitro and in vivo measures also provided evidence of diffusion exchange, which was quantified with the Diffusion Exchange Index (DEI). CONCLUSIONS Our findings provide preliminary evidence that DEXSY can be used to make in vivo measurements of diffusion exchange and cell membrane permeability.

Abstract
Identification of clonal IGH, IGK and IGL gene rearrangements offers diagnostic adjunct in suspected B-cell neoplasms. However, many centres omit IGL analysis as its value is uncertain. A review of 567 cases with IGH, IGK and IGL rearrangement assessed using BIOMED-2 assays showed clonal immunoglobulin gene rearrangement in 54% of cases, of which 24% had a clonal IGL rearrangement. In two cases, the clonal rearrangement was detected exclusively by IGL analysis. This finding demonstrates the added value of IGL analysis for clonality assessment, especially in suspected B-cell neoplasms in which a clonal IGH and/or IGK rearrangement is not detected or is equivocal.

Abstract
In the first hours or days after an unplanned release of radioactive material to the environment, the radiation detection instruments most widely available to local first responders may be those currently fielded for interdiction missions. This study investigated how such preventative radiological/nuclear detection instruments could perform if repurposed for consequence management missions. A representative sample of three archetypes (body-worn, human-carried, and other/large-detection-volume equipment) encompassed six categories: personal radiation detector, extended-range personal radiation detector, personal emergency radiation detector, radioisotope identification device, human-portable detector/backpack, and vehicle-mounted large-detection-volume detector. Overall 19 models of equipment were included in the study. Laboratory evaluations were designed to assess the capabilities of the instruments in four consequence management missions: exposure rate, integrated exposure, radiation survey, and contamination screening. As applicable, the evaluations included measurement of exposure rate, integrated exposure, overrange response, and angular response. The results were compared to benchmarks from the American National Standards Institute N42.49A. The performance of the instruments for initial screening for contamination was assessed by an automated radioactive source moving past the detectors at various speeds and distances. The results demonstrate that if the equipment is used in accordance with the mission analysis and categories and within the original equipment manufacturer specifications, it is possible to achieve sufficient accuracy to estimate and document doses to responders, plan entries into contaminated areas, detect contamination, and protect the public until such time as outside resources arrive with sufficient numbers of standard health physics instruments and personnel dosimetry to replace the preventative radiological/nuclear detection instruments. This evaluation campaign was conducted to complement the National Council on Radiation Protection and Measurements Report 179, Guidance for Emergency Response Dosimetry.

Abstract
PURPOSE Mutations in the mitochondrial enzyme succinate dehydrogenase (SDH) subunit genes are associated with a wide spectrum of tumours including phaeochromocytoma and paraganglioma (PPGL) 1, 2, gastrointestinal stromal tumours (GIST) 3, renal cell carcinoma (RCC) 4 and pituitary adenomas5. SDH-related tumorigenesis is believed to be secondary to accumulation of the oncometabolite succinate. Our aim was to investigate the potential clinical applications of MRI spectroscopy (1H-MRS) in a range of suspected SDH-related tumours. PATIENTS AND METHODS Fifteen patients were recruited to this study. Respiratory-gated single-voxel 1H-MRS was performed at 3T to quantify the content of succinate at 2.4 ppm and choline at 3.22 ppm. RESULTS A succinate peak was seen in six patients, all of whom had a germline SDHx mutation or loss of SDHB by immunohistochemistry. A succinate peak was also detected in two patients with a metastatic wild-type GIST (wtGIST) and no detectable germline SDHx mutation but a somatic epimutation in SDHC. Three patients without a tumour succinate peak retained SDHB expression, consistent with SDH functionality. In six cases with a borderline or absent peak, technical difficulties such as motion artefact rendered 1H-MRS difficult to interpret. Sequential imaging in a patient with a metastatic abdominal paraganglioma demonstrated loss of the succinate peak after four cycles of [177Lu]-DOTATATE, with a corresponding biochemical response in normetanephrine. CONCLUSIONS This study has demonstrated the translation into clinical practice of in vivo metabolomic analysis using 1H-MRS in patients with SDH-deficient tumours. Potential applications include non-invasive diagnosis and disease stratification, as well as monitoring of tumour response to targeted treatments.

Abstract
BACKGROUND Increasing evidence is becoming available on the aetiology and management of fevers in Asia; the importance of these fevers has increased with the decline in the incidence of malaria. AIMS To conduct a narrative review of the epidemiology and management of fevers in South and South-East Asia and to highlight gaps in our knowledge that impair evidence-based health policy decisions. SOURCES A narrative review of papers published since 2012 on developments in fever epidemiology, diagnosis and treatment in South and South-East Asia. The papers that the authors felt were pivotal, from their personal perspectives, are discussed. CONTENT We identified 100 studies. Among the 30 studies (30%)-including both children and adults-that investigated three or more pathogens, the most frequently reported fever aetiology was dengue (reported by 15, 50%), followed by leptospirosis (eight, 27%), scrub typhus (seven, 23%) and Salmonella serovar Typhi (six, 20%). Among four studies investigating three or more pathogens in children, dengue and Staphylococcus aureus were the most frequent, followed by non-typhoidal Salmonella spp, Streptococcus pneumoniae, Salmonella serovar Typhi, and Orientia tsutsugamushi. Increased awareness is needed that rickettsial pathogens are common but do not respond to cephalosporins, and that alternative therapies, such as tetracyclines, are required. IMPLICATIONS Many key gaps remain, and consensus guidelines for study design are needed to aid comparative understanding of the epidemiology of fevers. More investment in developing accurate and affordable diagnostic tests for rural Asia and independent evaluation of those already on the market are needed. Treatment algorithms, including simple biomarker assays, appropriate for empirical therapy of fevers in different areas of rural Asia should be a major aim of fever research. Enhanced antimicrobial resistance (AMR) surveillance and openly accessible databases of geography-specific AMR data would inform policy on empirical and specific therapy. More investment in innovative strategies facilitating infectious disease surveillance in remote rural communities would be an important component of poverty reduction and improving public health.

Abstract
Hereditary dentine dysplasias (HDD) such as dentinogenesis imperfecta (DI) and dentine dysplasia (DD) are a group of genetic conditions characterised by an abnormal dentine structure due to disturbances in the formation, composition, or organisation of the dentine matrix. Either the primary or both primary and secondary dentition are affected to varying degrees. These disorders result from mutations in the genes encoding the major protein constituents of dentine, notably collagens and phosphoproteins. The clinical and radiological features of the hereditary dentine dysplasias (HDD) are relevant to clinical dentistry, in particular osteogenesis imperfecta (OI) which is a well-known heterogeneous genetic disorder. OI is currently the focus of considerable academic attention and involvement of the teeth is a frequent and variable manifestation. In this analysis, the literature related to the classification, clinical features, and molecular pathogenesis of heritable structural tooth diseases affecting dentine formation is reviewed. The definition, history of the terminology and the development of the current classification is outlined and discussed in detail with the aim to address semantic confusion that has arisen in the literature on HDD and to provide clarity on the use of appropriate terminology in the context of OI.

Abstract
Aberrant activation of phosphatidylinosito-4,5-bisphosphate 3-kinase/protein kinase B (PI3K/AKT) signaling in cancer has led to pursuit of inhibitors for targeting this pathway. However, inhibitors of PI3K and AKT have failed to yield efficacious results without adverse effects. Here, we screened a library containing 441 authenticated traditional chinese medicine (TCM) plant extracts by examining their effect on cell viability of a human mammary epithelial cell line HMEC-PIK3CAH1047R, which expresses mutant PIK3CAH1047R and has constitutively active AKT signaling. We found that Oridonin, an extract from Rabdosia rubescens, reduced cell viability to the greatest extent. Oridonin binds to AKT1 and potentially functions as an ATP-competitive AKT inhibitor. Importantly, Oridonin selectively impaired tumor growth of human breast cancer cells with hyperactivation of PI3K/AKT signaling. Moreover, Oridonin prevented the initiation of mouse mammary tumors driven by PIK3CAH1047R. Our results suggest that Oridonin may serve as a potent and durable therapeutic agent for the treatment of breast cancers with hyperactivation of PI3K/AKT signaling.

Students' perceptions of STEM learning after participating in a summer informal learning experience. Int J STEM Educ 2018; 5:35. [PMID: 30631725 PMCID: PMC6310427 DOI: 10.1186/s40594-018-0133-4] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [What about the content of this article?

Abstract
BACKGROUND Informal learning environments increase students' interest in STEM (e.g., Mohr-Schroeder et al. School Sci Math 114: 291-301, 2014) and increase the chances a student will pursue a STEM career (Kitchen et al. Sci Educ 102: 529-547, 2018). The purpose of this study was to examine the impact of an informal STEM summer learning experience on student participants, to gain in-depth perspectives about how they felt this experience prepared them for their in-school mathematics and science classes as well as how it influenced their perception of STEM learning. Students' attitudes and perceptions toward STEM are affected by their motivation, experience, and self-efficacy (Brown et al. J STEM Educ Innov Res 17: 27, 2016). The academic and social experiences students' have are also important. Traditionally, formal learning is taught in a solitary form (Martin Science Education 88: S71-S82, 2004), while, informal learning is brimming with chances to connect and intermingle with peers (Denson et al. J STEM Educ: Innovations and Research 16: 11, 2015). RESULTS We used a naturalistic inquiry, phenomenological approach to examine students' perceptions of STEM while participating in a summer informal learning experience. Data came from students at the summer informal STEM learning experiences at three diverse institutions across the USA. Data were collected from reflection forms and interviews which were designed to explore students' "lived experiences" (Van Manen 1990, p. 9) and how those experiences influenced their STEM learning. As we used a situative lens to examine the research question of how participation in an informal learning environment influences students' perceptions of STEM learning, three prominent themes emerged from the data. The informal learning environment (a) provided context and purpose to formal learning, (b) provided students opportunity and access, and (c) extended STEM content learning and student engagement. CONCLUSIONS By using authentic STEM workplaces, the STEM summer learning experience fostered a learning environment that extended and deepened STEM content learning while providing opportunity and access to content, settings, and materials that most middle level students otherwise would not have access to. Students also acknowledged the access they received to hands-on activities in authentic STEM settings and the opportunities they received to interact with STEM professionals were important components of the summer informal learning experience.

Abstract
INTRODUCTION Dental professionalism is an essential requirement to practice dentistry that covers both abilities and personal qualities. Therefore, a programme of assessment that promotes personal and professional development throughout the undergraduate dental education course is needed. This study aimed to develop and validate a system to assess dental students' professionalism based on a previously developed conceptual framework. METHODS Using the framework, an assessment programme was designed to encourage students to reflect on and explain their observed behaviours with appropriate feedback. The programme was panel-tested and then administered to a cohort of senior dental students. Internal reliability criterion validity and construct validity were evaluated quantitatively, whilst the usefulness of the programme was evaluated qualitatively. RESULTS Mean of student, staff and agreed grades was similar, and there were no floor or ceiling effects. All item-total correlations were >0.6 and Cronbach's alpha = 0.95 indicating acceptable internal reliability. All items correlated significantly with global ratings indicating good criterion validity. All hypothesized correlations were significant, and grades were not related to age or gender. Qualitative data produced three themes: assessment process, educational value and suggestions for improvement. CONCLUSION The assessment programme has good internal reliability and validity and suggests that basing an assessment system around the explicit theoretical model is a valuable educational tool.

Abstract
CONTEXT The co-occurrence of pheochromocytoma (PC) and renal tumors was linked to the inherited familial cancer syndrome von Hippel-Lindau (VHL) disease more than six decades ago. Subsequently, other shared genetic causes of predisposition to renal tumors and to PC, paraganglioma (PGL), or head and neck paraganglioma (HNPGL) have been described, but case series of non-VHL-related cases of renal tumor and pheochromocytoma/paraganglioma tumor association syndrome (RAPTAS) are rare. OBJECTIVE To determine the clinical and molecular features of non-VHL RAPTAS by literature review and characterization of a case series. DESIGN A review of the literature was performed and a retrospective study of referrals for investigation of genetic causes of RAPTAS. RESULTS Literature review revealed evidence of an association, in addition to VHL disease, between germline mutations in SDHB, SDHC, SDHD, TMEM127, and MAX genes and RAPTAS [defined here as the co-occurrence of tumors from both classes (PC/PGL/HNPGL and renal tumors) in the same individual or in first-degree relatives]. In both the literature review and our case series of 22 probands with non-VHL RAPTAS, SDHB mutations were the most frequent cause of non-VHL RAPTAS. A genetic cause was identified in 36.3% (8/22) of kindreds. CONCLUSION Renal tumors and PC/PGL/HNPGL tumors share common molecular features and their co-occurrence in an individual or family should prompt genetic investigations. We report a case of MAX-associated renal cell carcinoma and confirm the role of TMEM127 mutations with renal cell carcinoma predisposition.

Abstract
The early detection and endoscopic treatment of patients with the dysplastic stage of Barrett's oesophagus is a key to preventing progression to oesophageal adenocarcinoma. However, endoscopic surveillance protocols are hampered by the invasiveness of repeat endoscopy, sampling bias, and a subjective histopathological diagnosis of dysplasia. In this case-control study, we investigated the use of a non-invasive, pan-oesophageal cell-sampling device, the Cytosponge™, coupled with a cancer hot-spot panel to identify patients with dysplastic Barrett's oesophagus. Formalin-fixed, paraffin-embedded (FFPE) Cytosponge™ samples from 31 patients with non-dysplastic and 28 with dysplastic Barrett's oesophagus with good available clinical annotation were selected for inclusion. Samples were microdissected and amplicon sequencing performed using a panel covering >2800 COSMIC hot-spot mutations in 50 oncogenes and tumour suppressor genes. Strict mutation criteria were determined and duplicates were run to confirm any mutations with an allele frequency <12%. When compared with endoscopy and biopsy as the gold standard the panel achieved a 71.4% sensitivity (95% CI 51.3-86.8) and 90.3% (95% CI 74.3-98.0) specificity for diagnosing dysplasia. TP53 had the highest rate of mutation in 14/28 dysplastic samples (50%). CDKN2A was mutated in 6/28 (21.4%), ERBB2 in 3/28 (10.7%), and 5 other genes at lower frequency. The only gene from this panel found to be mutated in the non-dysplastic cases was CDKN2A in 3/31 cases (9.7%) in keeping with its known loss early in the natural history of the disease. Hence, it is possible to apply a multi-gene cancer hot-spot panel and next-generation sequencing to microdissected, FFPE samples collected by the Cytosponge™, in order to distinguish non-dysplastic from dysplastic Barrett's oesophagus. Further work is required to maximize the panel sensitivity.

Abstract
This study focused on a clinically relevant healthcare problem in the military: acute soft tissue wounds, or blisters. The trial was a prospective, controlled, randomized two-arm study evaluating the efficacy of a bioelectric dressing, Procellera®, applied topically two to three times per week for 2 weeks to blisters developed in Ranger trainees during training at Fort Benning, Georgia. A total of 80 US Army Ranger recruits with blister wounds below the knee were randomly assigned to one of two treatment groups (n = 40/group). The primary goal was to assess the clinical efficacy (rate of healing) of administered Procellera in conjunction with the standard-of-care (SOC) treatment, moleskin and Tegaderm ®, on the healing rate of blisters compared with the SOC treatment alone. The secondary end points for efficacy were the quantities of wound fluid biomarkers and bacterial bioburden. The tertiary end point was assessment of pain in the treatment group compared with that of the control group during the 2-week study. The results showed no statistical difference between the SOC and SOC+Procellera groups in wound healing and pain. Wound fluid was reported for 24 participants (64.9%) in the SOC group and 21 participants (56.8%) in SOC+Procellera group at the baseline measurement (ρ = .475); however, the wounds were devoid of fluid on follow-up visits. The mild nature of the wounds in this study was apparent by the low pain scores at the beginning of the study, which disappeared by the follow-up visits. The average wound sizes were 2.2cm2 and 1.5cm2 for the SOC and SOC+Procellera groups, respectively. This trial protocol should be conducted on open softtissue wounds in severe heat. To our knowledge, this is the first clinical study conducted within the US Army Rangers training doctrine.

Abstract
BACKGROUND Sarcoidosis is a chronic, multisystem disease characterised by non-necrotising granulomatous inflammation of unknown aetiology. Most commonly, the lungs, lymph nodes, skin and eyes are affected in sarcoidosis; however, nervous system involvement occurs in approximately 5%-15% of cases. Any part of the nervous system can be affected by sarcoidosis. CASES Herein we describe three unusual patient presentations of neurosarcoidosis, one with optic neuritis, a second with hydrocephalus and a third with cervical myelopathy. CONCLUSIONS We include pertinent details about their presentations, imaging findings, pathology, management and clinical course.
