Abstract
OBJECTIVES To assess how biomarkers indicating central nervous system insult (neurobiomarkers) vary in peripheral blood with exertional-heat stress from prolonged endurance exercise. DESIGN Observational study of changes in neuron specific enolase (NSE), S100 calcium-binding protein B (S100β), Glial Fibrillary Acid Protein (GFAP) and Ubiquitin carboxyl-terminal hydrolase isozyme L1 (UCHL1) at Brighton Marathon 2022. METHODS In 38 marathoners with in-race core temperature (Tc) monitoring, exposure (High, Intermediate or Low) was classified by cumulative hyperthermia - calculated as area under curve of Time × Tc > 38 °C - and also by running duration (finishing time). Blood was sampled for neurobiomarkers, cortisol and fluid-regulatory stress surrogates, including copeptin and creatinine (at rested baseline; within 30 min of finishing; and at 24 h). RESULTS Finishing in 236 ± 40 min, runners showed stable GFAP and UCH-L1 across the marathon and next-day. Significant (P < 0.05) increases from baseline were shown post-marathon and at 24 h for S100β (8.52 [3.65, 22.95] vs 39.0 [26.48, 52.33] vs 80.3 [49.1, 99.7] ng·L-1) and post-marathon only for NSE (3.73 [3.30, 4.32] vs 4.85 [4.45, 5.80] μg·L-1, P < 0.0001). Whilst differential response to hyperthermia was observed for cortisol, copeptin and creatinine, neurobiomarker responses did not vary. Post-marathon, only NSE differed by exercise duration (High vs Low, 5.81 ± 1.77 vs. 4.69 ± 0.73 μg·L-1, adjusted P = 0.0358). CONCLUSIONS Successful marathon performance did not associate with evidence for substantial neuronal insult. To account for variation in neurobiomarkers with prolonged endurance exercise, factors additional to hyperthermia, such as exercise duration and intensity, should be further investigated.

Abstract
Emergency airway management events are common, unpredictable and associated with high complication rates. This multicentre prospective observational study across eight acute NHS hospitals in southeast England reports the incidence and nature of non-theatre emergency airway management events. Data were collected from non-theatre emergency airway management, including adverse events, over a continuous 28-day window, and recorded on an electronic case report form. Events were classified according to type (advanced airway; simple airway; and cardiac arrest). A total of 166 events were recorded, with 111 advanced airway events involving tracheal intubation or tracheostomy management. Senior personnel with three or more years of airway management experience were present for 105/111 (95%) advanced airway management episodes. There was a significant reduction in consultant or equivalent presence out-of-hours (21/64, 33%) vs. in-hours (34/47, 72%) (p < 0.001). We found high utilisation of videolaryngoscopy (95/106, 90%) and universal use of capnography for all advanced airway management events. This was lower during cardiac arrest when videolaryngoscopy was used in 11/16 (69%) of tracheal intubations and capnography in 21/32 (66%) of all cardiac arrest episodes. Adverse outcomes during advanced airway management (excluding during cardiac arrest) occurred in 53/111 (48%) episodes, including hypoxia (desaturation to Sp O2 < 80% in 14/111, 13%) and hypotension (systolic blood pressure < 80 mmHg in 27/111, 25%). Adverse outcomes were not associated with time of day or experience level of airway practitioners. We conclude that there is a disparity between consultant presence for advanced airway interventions in- and out-of-hours; high utilisation of videolaryngoscopy and capnography, especially for advanced airway interventions; and a high incidence of hypotension and hypoxaemia, including critical values, during non-theatre airway management.

Abstract
Good foot health throughout childhood is important but remains poorly understood with few studies exploring this topic. The aim of this study was to define parents' knowledge, practices and health-related perceptions of children's feet. A qualitative design was adopted. Semi-structured, one-to-one interviews were carried out with parents of children aged five years and under, recruited from South East and North West of England. Interviews explored parents' views, beliefs and understanding of foot health in infancy and early childhood. Transcripts of the interviews were analysed using thematic analysis. Eighteen interviews were conducted. Seven themes were identified relating to (1) parents belief and knowledge about children's foot health; (2) how parents use and share foot health information; (3) activities for supporting foot health and development; (4) footwear choices, beliefs and influences; (5) the way they access health professionals; (6) the way they search for foot health information and (7) developing practice(s) to support parents. The study provides the first insight into how parents view foot health in early infancy and childhood. The findings highlight the key foot health beliefs important to parents, how they learn about and what influences their decision-making about caring for children's feet, the way parents receive and seek information, and how they access support for foot health concerns. The findings highlight the need for accurate, clear and consistent foot health messages, and the important role health professionals have in signposting parents towards reliable and informative sources on foot health.

Abstract
The aim of the present study was to investigate whether ingestion of polyphenol-rich dark chocolate improved salivary cortisol levels and subjective mood states in adults recruited from a health and social care setting. Twenty-six participants ingested 25 g/day of a high polyphenol dark chocolate (containing 500 mg of total flavonoids) or a similar amount of a control dark chocolate containing negligible flavonoids for four weeks. Twenty-four-hour salivary glucocorticoid levels (cortisol and cortisone) were measured by an enzyme-linked immunosorbent assay, and subjective mood was assessed using a validated Positive Affect and Negative Affect Schedule. Total daily cortisol, morning cortisol, and the cortisol/cortisone ratio were significantly reduced (p < 0.001) after ingestion of only the high polyphenol dark chocolate. There were no significant differences between groups for overall scores for positive affect and negative affect. No changes were observed after the control dark chocolate, or any other parameter measured. In conclusion, the findings from this small-scale study indicate lowering of salivary cortisol levels following polyphenol-rich dark chocolate in adults recruited from a health and social care setting. Such changes may be attributable to their ability to inhibit 11β-hydroxysteroid dehydrogenase type 1 activity and warrant further investigation.

Abstract
<p>The current literature does not offer convincing evidence for
the positive effect of antivenom on time to recovery in dogs envenomated by
the European adder. It appears that the use of antivenom in addition to
supportive treatment may positively affect local swelling if given within 24
hours of the bite, but the evidence is low quality and further studies are
required before a more definitive answer can be
reached.</p><p><br /> <img

Abstract
PURPOSE To establish a comprehensive set of recommendations for the service structure and skill set of nurses and allied healthcare professionals in prostate cancer care. METHODS Using components of formal consensus methodology, a 30-member multidisciplinary panel produced 53 items for discussion relating to the provision of care for prostate cancer patients by specialist nurses and allied healthcare professionals. Items were developed by two rounds of email correspondence in which, first, items were generated and, second, items refined to form the basis of a consensus meeting which constituted the third round of review. The fourth and final round was an email review of the consensus output. RESULTS The panel agreed on 33 items that were appropriate for recommendations to be made. These items were grouped under categories of "Environment" and "Patient Pathway" and included comments on training, leadership, communication and quality assessment as well as specific items related to prostate diagnosis clinics, radical treatment clinics and follow-up survivor groups. CONCLUSIONS Specialist nurses and allied healthcare professionals play a vital role alongside urologists and oncologists to provide care to men with prostate cancer and their families. We present a set of standards and consensus recommendations for the roles and skill-set required for these practitioners to provide gold-standard prostate cancer care. These recommendations could form the basis for development of comprehensive integrated prostate cancer pathways in prostate cancer centres as well as providing guidance for any units treating men with prostate cancer.

Abstract
Most cancer patients die as a result of metastasis, thus it is important to understand the molecular mechanisms of dissemination, including intra- and extravasation. Although the mechanisms of extravasation have been vastly studied in vitro and in vivo, the process of intravasation is still unclear. Furthermore, how cells in the tumor microenvironment facilitate tumor cell intravasation is still unknown. Using high-resolution imaging, we found that macrophages enhance tumor cell intravasation upon physical contact. Macrophage and tumor cell contact induce RhoA activity in tumor cells, triggering the formation of actin-rich degradative protrusions called invadopodia, enabling tumor cells to degrade and break through matrix barriers during tumor cell transendothelial migration. Interestingly, we show that macrophage-induced invadopodium formation and tumor cell intravasation also occur in patient-derived tumor cells and in vivo models, revealing a conserved mechanism of tumor cell intravasation. Our results illustrate a novel heterotypic cell contact mediated signaling role for RhoA, as well as yield mechanistic insight into the ability of cells within the tumor microenvironment to facilitate steps of the metastatic cascade.

Abstract
Early hominids searched for dispersed food sources in a patchy, uncertain environment, and modern humans encounter equivalent spatial-temporal coordination problems on a daily basis. A fundamental, but untested assumption is that our evolved capacity for communication is integral to our success in such tasks, allowing information exchange and consensus decisions based on mutual consideration of pooled information. Here we examine whether communication enhances group performance in humans, and test the prediction that consensus decision-making underlies group success. We used bespoke radio-tagging methodology to monitor the incremental performance of communicating and non-communicating human groups (small group sizes of two to seven individuals), during a social foraging experiment. We found that communicating groups (n = 22) foraged more effectively than non-communicating groups (n = 21) and were able to reach consensus decisions (an 'agreement' on the most profitable foraging resource) significantly more often than non-communicating groups. Our data additionally suggest that gesticulations among group members played a vital role in the achievement of consensus decisions, and therefore highlight the importance of non-verbal signalling of intentions and desires for successful human cooperative behaviour.

Abstract
AIMS/HYPOTHESIS The purpose of the study was to evaluate the association between retinal vascular calibre and micro- and macrovascular complications in a population-based cohort of Danish type 1 diabetic patients. METHODS This was a cross-sectional study of 208 long-surviving type 1 diabetic patients from a population-based Danish cohort. Retinal photographs were obtained at a clinical examination attended by each participant in 2007-2008, and retinal vascular calibre was measured and summarised as the central retinal artery or vein equivalent (CRAE or CRVE) using a computer-based program and a standardised protocol. Associations between retinal vascular calibre and micro- and macrovascular complications were examined after adjusting for confounding clinical characteristics. RESULTS Retinal photographs were gradable for 188 of 208 patients (90.3%). The median age and duration of diabetes for patients with gradable photos were 57.9 and 42 years, respectively. After multivariate adjustments, individuals with narrower retinal arterioles were more likely to have nephropathy (OR 2.17, 95% CI 1.29-3.68, per SD decrease in CRAE) and macrovascular disease (OR 3.17, 95% CI 1.59-6.34, per SD decrease in CRAE), but not neuropathy (OR 1.10, 95% CI 0.70-1.71, per SD decrease in CRAE). Retinal venular calibre was not associated with any micro- or macrovascular complications. CONCLUSIONS/INTERPRETATION In type 1 diabetic patients, retinal arteriolar narrowing is associated with nephropathy and macrovascular disease independently of other clinical characteristics. If supported by further prospective studies, measurement of retinal vessel diameter may allow a non-invasive evaluation of the risk of diabetes-related complications.

Abstract
11020 Background: Cytokeratin 19 and its soluble fragment CYFRA have been studied as markers that may correlate with response to therapy and survival in NSCLC. As part of CALGB 30203, a randomized trial of carboplatin/gemcitabine with eicosanoid modulators (celecoxib, zileuton or both) in advanced NSCLC (Edelman JCO 2008), serum CYFRA levels were obtained prior to and during treatment. The objective of this study was to evaluate the possible correlation of CYFRA as a predictive and prognostic marker and to confirm a previous finding that a 27% reduction in CYFRA after one cycle (21 days) of treatment correlated with a longer survival (Vollmer Clin Ca Res, 2003). Methods: Paired specimens were available from 88 patients. CYFRA was measured at baseline and after cycles 1 and 2 using an electrochemoluminescent assay (Roche Diagnostics) on the ElecSys 2010 system as previously described. Using logarithm of the initial concentration and logarithm of the difference in concentrations, we analyzed these in relation to overall survival (OS) and failure free survival (FFS). Results: 1. Lower baseline CYFRA levels were associated with both longer overall survival and failure free survival (p = <0.0001 and p=0.0045). 2. Larger reductions in CYFRA levels correlated to longer overall survival and failure-free survival (p=0.0254 and p=0.0298). 3.We failed to replicate that a drop of >27% in CYFRA levels had statistical significance in overall or failure free survival (p=0.6489 and p=0.9636). Conclusions: CYFRA and change in CYFRA appear to be reliable markers in predicting the response to chemotherapy for nonsmall cell lung cancer; however, a precise threshold to mark response has yet to be determined. No significant financial relationships to disclose.

Abstract
7535 Background: CALGB 39801 was designed to test whether treatment with induction chemotherapy and concurrent chemoradiotherapy (arm B) would improve OS in comparison to identical chemoradiotherapy alone (arm A), and demonstrated no significant benefit in OS for induction therapy. The objective of this analysis was to identify factors predictive of OS, and to use relevant factors to dichotomize pts into prognostic groups. Methods: Between July 1998 and May 2002, 331 pts were studied and included in a Cox proportional hazard regression analysis investigating previously identified prognostic factors: age (< 70 vs. ≥ 70 years), gender, race/ethnicity, hemoglobin (hgb) (< 13 vs. ≥13), performance status (PS) (0 vs.1), pretreatment weight loss (wt loss) (<5% vs. ≥ 5%), and treatment arm. Results: Cox regression analysis identified weight loss ≥ 5%, age ≥ 70, PS of 1, and hgb < 13 as predictive of worse survival (p<0.05), but not treatment arm (p=0.55). The median survival for pts with 0 (n=66), 1 (n=100), 2 (n=100), or ≥ 3 (n=65) risk factors were 24, 18, 10, and 8 months, respectively (p=0.0001). The pts were dichotomized into “poor prognosis” (PP) defined as ≥2 factors (n=165) and “good prognosis” (GP) defined as ≤ 1 factors (n=166). The hazard ratio (HR) for overall survival for the PP in comparison GP was 1.88 (95% CI, 1.49 to 2.37; p-value < 0.0001); the median survival times (MST) observed were 9 and 18 months, respectively (p<0.0001). The reasons for discontinuing treatment, and the rates of hematologic and non-hematologic adverse events were similar between the two groups. In the PP group the OS was similar between arms A (n=82) and B (n=83) (HR=0.97, 95% CI, 0.70 to 1.4; p=0.34); MST of 8.7 and 9.5 months, respectively. In the GP the OS was similar between arms A (n=79) and B (n=87) (HR=0.86, 95% CI, 0.63 to 1.1; p=0.87); MST of 19.3 and 17.6 months, respectively. Conclusions: Factors predictive of OS can be used to dichotomize pts into prognostic groups. Induction chemotherapy was not beneficial in either prognostic group. No significant financial relationships to disclose.

Abstract
7505 Background: Cisplatin, etoposide and concurrent thoracic radiation has remained the standard treatment for locally advanced unresectable non small cell lung cancer (NSCLC) over the past two decades. The Cancer and Leukemia Group B (CALGB) conducted a phase II study using a novel chemotherapy regimen administered in systemically active doses with thoracic radiation (CALGB 30407). We previously reported the preliminary safety results (ASCO 2008, abstract 7518). Methods: Eligible patients with previously untreated stage III NSCLC received thoracic radiation (70 Gy) along with carboplatin (AUC 5) and pemetrexed 500 mg/m2 on day 1 administered intravenously every 21 days for 4 cycles (arm A) or the same chemotherapy regimen with weekly cetuximab for 6 weeks concurrent with radiation (arm B). All patients received four additional cycles of pemetrexed (500 mg/m2 every 21 days) as consolidation therapy. The primary endpoint was the percentage of patients who lived longer than 18 months after starting initial treatment. We planned to study the regimen (s) further if the 18 month survival rates equaled or exceeded 55%. Results: Characteristics of the 99 eligible pts (48 in arm A and 51 arm B) enrolled from 09/05 to 1/08: male 62%, 22% were 70 yrs or older. The most common histological type was adenocarcinoma (46% in Arm A and 41% in Arm B). Updated toxicity data (grade 3 or greater, %) by arms (arm A/arm B) for 106 pts: neutropenia 40/47; febrile neutropenia 8/6, thrombocytopenia 36/34, nausea/vomiting 8/10, esophagitis 32/24, skin rash 2/21 and fatigue 22/17. The median follow up time is 17 months. Preliminary efficacy data by arms (arm A/arm B) for 99 pts: complete or partial response 73% (95% CI 59–83)/71% (95% CI 57–81%), median failure free survival (months) 12.9 (95% CI 8.6–18.0)/10.3 (95% CI 8.7–18.9); 18 month survival 57% (95% CI 41–79)/47% (95% CI 33–67) and median survival (months) 22.3/18.7. Conclusions: The combination of pemetrexed, carboplatin and thoracic radiation has met the protocol-specified criteria for further study. Although it does not appear that the addition of cetuximab confers additional benefit in this setting, further follow-up is necessary. [Table: see text]

Abstract
7707 Background: Systemic chemotherapy with cisplatin/pemetrexed is the approved first line treatment regimen for patients with MM. There is no approved second line therapy. In addition, many patients, especially those >70, cannot tolerate combination chemotherapy. Angiogenesis inhibitors have emerged as attractive potential therapies for MM and SU5416 and PTK787 have previously demonstrated single agent activity. We examined the efficacy of sorafenib, an inhibitor of VEGFR2 and PDGFR-b, in chemotherapy naïve and previously treated patients with MM. Methods: This was an open label single arm phase II study of sorafenib in chemotherapy naïve and previously pemetrexed treated patients with MM. Primary end point was response rate (RR). Secondary objectives were 3-month failure free and overall survival (FFS and OS). Forty-four (44) eligible patients were expected to enroll to differentiate a RR of <5% versus >20%, with a Type I error of 0.0675 and a power of 0.955 Results: Between 10/04 and 8/05, 51 patients were enrolled and treated with sorafenib 400 mg bid. One cycle was defined as 28 days; restaging occurred every 2 cycles. Baseline demographics: M/F (36/15); Median age (69; range 36–88; 45% >70); Histology (epithelial/sarcomatoid/mixed/unknown: 37/4/8/2); pleural/peritoneal MM (46/5); ECOG PS 0/1 (11/40); chemo-naive/prior chemo (20/31). Grade 3/4 toxicities occurring in >10% of patients: Fatigue (12 (25%); 11/1) and hand-foot reaction (6 (13%); 6/0). No study related deaths occurred. Estimates of RR and FFS are based on 47 patients with available follow-up data. Response: CR: 0; PR 2: 4% (95% CI; 1- 14%); SD 28 (60%); PD 11 (23%); unevaluable 6 (14%). Three month FFS was 78%; median FFS was 3.7 months and median OS was 10.7 months. The median FFS were 3.6 and 3.6 months and the median OS were 4.9 and 14.6 months in chemo naïve and previously treated patients, respectively. Conclusions: Sorafenib demonstrated modest activity in this phase II trial but did not meet its primary endpoint. The improved outcome in previously treated patients likely reflects patient selection. Ongoing correlative science studies including expression of p-ERK 1/2, baseline VEGF and PDGF levels, are being performed to help identify patient subsets who may benefit (PR or SD) from sorafenib.

Abstract
We have investigated cellular Ca2+ regulation during A2058 human melanoma cell chemotaxis to type IV collagen (CIV). We have identified alpha2beta1-integrin as the primary mediator of A2058 cell response to CIV in vitro. Integrin ligation initiated a characteristic intracellular Ca2+ concentration ([Ca2+]i) response consisting of an internal release and a receptor-mediated Ca2+ entry. Thapsigargin (TG) pretreatment drained overlapping and CIV-inducible internal Ca2+ stores while initiating a store-operated Ca2+ release (SOCR). CIV-mediated Ca2+ entry was additive to TG-SOCR, suggesting an independent signaling mechanism. Similarly, ionophore application in a basal medium containing Ca2+ initiated a sustained influx. Elevated [Ca2+]i from TG-SOCR or ionophore significantly attenuated cell migration to CIV by recruiting the Ca2+/calcineurin-mediated signaling pathway. Furthermore, low [Ca2+]i induced by EGTA application in the presence of ionophore fully restored cell motility to CIV. Together, these results suggest that [Ca2+]i signaling accompanying A2058 cell response to alpha2beta1-integrin ligation is neither necessary nor sufficient and that elevated [Ca2+]i downregulates cell motility via a calcineurin-mediated mechanism in A2058 cell chemotaxis to CIV.

Abstract
OBJECTIVE To compare the pain relief, sedation, and common side effect profiles of ketorolac tromethamine and meperidine for the management of acute pain in the emergency department (ED). METHODS A prospective, double-blind, randomized clinical trial was conducted over a 12-month period using consecutive adult patients presenting to a university teaching hospital ED (annual census: 32,000), who required IM analgesia for acute pain. Adult patients with acute pain of various etiologies were randomly assigned to receive a single fixed IM dose of ketorolac (60 mg) or meperidine (100 mg). RESULTS Ninety-three patients were enrolled in the study; 46 were randomized to meperidine and 47 to ketorolac. Using a visual analog scale, there was no difference in pain relief between the ketorolac and meperidine groups even after adjusting for baseline pain level. Ketorolac caused significantly (p < 0.005) less sedation than did meperidine at one hour. Rescue analgesia was required for seven of the 46 (15.2%) patients receiving meperidine and five of the 47 (10.6%) patients receiving ketorolac (p = NS). Seventeen of 45 (38%) patients receiving meperidine experienced side effects compared with eight of the 47 (17%) patients receiving ketorolac (p = 0.0452). CONCLUSIONS When used to treat patients who had acute pain states, 60 mg of IM ketorolac produced analgesia similar to that produced by 100 mg of IM meperidine; however, the ketorolac produced fewer subjective side effects and less sedation than did the meperidine.

Abstract
The 365 nm pulsed laser photolysis of nitrosyl chloride adsorbed on a rough MgO(100) surface at 90 K has been studied. Mass spectrometric detection was used to record time-of-flight (TOF) spectra by monitoring Cl+ and NO+. These ions can derive from parent ClNO, which fragments completely in the mass spectrometer, as well as from Cl and NO photofragments. The TOF distributions are considerably slower than for the corresponding gas phase photodissociation process. NO was also detected state selectively by using resonance enhanced multiphoton ionization (REMPI), and a channel corresponding to direct adsorbate photolysis was identified. The state selective detection of NO molecules that emerge from the surface following photolysis shows unambiguously that their rotational degrees of freedom reflect the surface temperature (Trot = 100−140 K), even at low coverages. At similar photolysis wavelengths, gas phase ClNO photodissociation is known to produce highly rotationally excited NO with a distinctive non-statistical distribution peaked at J″ = 46.5. Our studies suggest that, contrary to the gas-phase photolysis results, Cl and NO are not ejected rapidly following photolysis of surface-bound species on a repulsive potential energy surface. We postulate that ClNO grows in islands, with MgO defect sites serving as nucleation centers. Photofragment rotational and translational excitations are quenched efficiently due to strong attractive interactions that equilibrate NO to the surface temperature. Desorption of intact ClNO may also take place, but following (i.e., not during) the photolysis pulse. Such desorbed species can contribute to the TOF spectra, but not the REMPI spectra.
