Abstract
PURPOSE Health service use is most intensive in the final year of a person's life, with 80% of this expenditure occurring in hospital. Close involvement of primary care services has been promoted to enhance quality end-of-life care that is appropriate to the needs of patients. However, the relationship between primary care involvement and patients' use of hospital care is not well described. This study aims to examine primary care use in the last year of life for cancer patients and its relationship to hospital usage. METHODS Retrospective cohort study in Victoria, Australia, using linked routine care data from primary care, hospital and death certificates. Patients were included who died related to cancer between 2008 and 2017. RESULTS A total of 758 patients were included, of whom 88% (n = 667) visited primary care during the last 6 months (median 9.1 consultations). In the last month of life, 45% of patients were prescribed opioids, and 3% had imaging requested. Patients who received home visits (13%) or anticipatory medications (15%) had less than half the median bed days in the last 3 months (4 vs 9 days, p < 0.001, 5 vs 10 days, p = 0.001) and 1 month of life (0 vs 2 days, p = 0.002, 0 vs 3 days, p < 0.001), and reduced emergency department presentations (32% vs 46%, p = 0.006, 31% vs 47% p < 0.001) in the final month. CONCLUSION This study identifies two important primary care processes-home visits and anticipatory medication-associated with reduced hospital usage and intervention at the end of life.

Abstract
The lower limb is a common site for melanoma in women, but the reason for this is not fully understood. To investigate this phenomenon in more detail, we assessed the specific subsites of primary melanoma occurring on the lower limbs of females compared with males across age groups. In a records-based study at an oncology hospital in north-west of England, among an unselected sample of patients with primary invasive melanoma treated between 2002-2015, information was collected on patient age at diagnosis, sex, and co-morbidities, and the tumor thickness and anatomical subsite (thigh, lower leg, foot for lower limb). Of a total sample of 1,522 patients, 316 (227, 72% female) had lower limb melanoma. The most common subsite was lower leg (142 cases with F:M ratio =3.74), followed by thigh (55 cases with F:M = 1.83) and feet (30 cases with F:M = 1.15). At ages <40 years the odds of thigh to foot melanoma was 20 times higher in females than in males (OR 20.0, 95% CI 2.6-152.6) and 7.5 times higher on the lower limb (OR 7.5, 95% CI 1.1-49.2). For ages 40+ years, the odds of females developing thigh melanoma compared to foot melanoma was similar in males versus females (OR 0.8), while the corresponding odds of lower leg melanoma in females versus males remained significantly increased at ages 40-59 and 60+ (OR 4.2 and 2.8 respectively). Our study demonstrates the female predilection for lower limb melanoma persists over most but not all subsites.However, there is heterogeneity in the female to male occurence of lower limb melanoma across subsites and at different ages, which may be linked to relative influence of genetic and environmental risk factors.

Abstract
BACKGROUND Few studies have attempted to define clusters of chronic disease predictors with additional focus on racial/ethnic differences. The purpose of this study was to highlight differences in predictors of chronic diseases among American high school students by identifying subgroups using latent class analysis (LCA). METHODS The chronic disease predictor variable used in the analysis was created from 5 modified items in the 2019 Youth Risk Behavior Surveillance that were identified to be critical to healthy lifestyles in Healthy People 2020. Descriptive, bivariate, multinomial logistic regression and LCA were performed using SAS 9.4 and Mplus in 9th to 12th grade students, using data from the Youth Risk Behavior Survey (N = 13,677). RESULTS Three distinct classes emerged for US high school students and were characterized as high, moderate, and low risk of chronic disease (38%, 33%, and 29%, respectively). Black and Asian students had a higher chance of being in the high-risk class of chronic diseases. IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY Emphasis should be placed on sociocultural and socio-environmentally structured prevention programs for at risk/students, ensuring that policy formation reflects the language, identity, and needs of the populations at risk. CONCLUSIONS The behavioral similarities of the classes identified highlight the need for continued research, novel interventions, and culturally sensitive strategies and policies in US high schools.

Abstract
Background Relapse remains the primary cause of death after hematopoietic cell transplantation (HCT) for acute leukemia. The ability to identify minimal/measurable residual disease (MRD) via the blood could identify patients earlier when immunologic interventions may be more successful. We evaluated a new test that could quantify blood tumor mRNA as leukemia MRD surveillance using droplet digital PCR (ddPCR). Methods The multiplex ddPCR assay was developed using tumor cell lines positive for the tumor associated antigens (TAA: WT1, PRAME, BIRC5), with homeostatic ABL1. On IRB-approved protocols, RNA was isolated from mononuclear cells from acute leukemia patients after HCT (n = 31 subjects; n = 91 specimens) and healthy donors (n = 20). ddPCR simultaneously quantitated mRNA expression of WT1, PRAME, BIRC5, and ABL1 and the TAA/ABL1 blood ratio was measured in patients with and without active leukemia after HCT. Results Tumor cell lines confirmed quantitation of TAAs. In patients with active acute leukemia after HCT (MRD+ or relapse; n=19), the blood levels of WT1/ABL1, PRAME/ABL1, and BIRC5/ABL1 exceeded healthy donors (p<0.0001, p=0.0286, and p=0.0064 respectively). Active disease status was associated with TAA positivity (1+ TAA vs 0 TAA) with an odds ratio=10.67, (p=0.0070, 95% confidence interval 1.91 - 59.62). The area under the curve is 0.7544. Changes in ddPCR correlated with disease response captured on standard of care tests, accurately denoting positive or negative disease burden in 15/16 (95%). Of patients with MRD+ or relapsed leukemia after HCT, 84% were positive for at least one TAA/ABL1 in the peripheral blood. In summary, we have developed a new method for blood MRD monitoring of leukemia after HCT and present preliminary data that the TAA/ABL1 ratio may may serve as a novel surrogate biomarker for relapse of acute leukemia after HCT.

Abstract
Background Community pharmacies use text message communications for information regarding approaching refills and fill status. Patients can also be notified regarding annual influenza vaccine availability and schedule an appointment for the vaccine. Objectives This study aimed to evaluate whether text message communications affected patient presentation and resulted in a percent increase of patients receiving an influenza vaccine compared with previous vaccine season and to determine whether additional vaccines are administered upon presentation. Methods Ambidirectional study retrospectively analyzed the impact, nationally, of a new text message communication on influenza vaccinations at a large community pharmacy chain and prospectively surveyed patients receiving an influenza vaccine at 2 geographically similar pharmacies of the chain in Southwest Virginia. Text message communications regarding vaccine and appointment availability were sent to patients at the age of 18 years and older who opted in to text message communications and received an influenza vaccine with the chain during the 2019-2020 influenza season. Vaccine data from consecutive seasons were compared. Eligible patients in Southwest Virginia were surveyed about how they were informed about availability, previous intent to receive an influenza vaccine, applicability to other vaccines, and effect of the coronavirus disease 2019 pandemic on vaccination. Results were analyzed using bivariate and multivariate analyses. Results Nationally, influenza vaccines administered increased by 17.45% in patients who permitted text message communication and overall by 13.22% after implementation. Decreases in co-administered pneumococcal vaccines and tetanus, diphtheria, and pertussis vaccines and an increase in co-administered zoster vaccines were observed. A total of 111 patients were surveyed; 4% presented owing to text message communication. A majority were intent on receiving the vaccine before being notified and reported that the pandemic did not affect presentation. Notably, 45.05% of patients were likely to receive routine vaccines if notified by text message. Conclusion Text message communications are another viable way to increase vaccinations, but further studies should be conducted outside of a pandemic setting.

Abstract
Abstract
Background
Social media (SoMe) enable the dissemination of content immediately and directly to interested end-users. Alternative metrics (altmetrics) are non-traditional bibliometrics which describe the exposure and impact of an article on freely available platforms such as Twitter and Facebook. Altmetrics within days of publication are associated with ultimate citation counts in various medical disciplines, except plastic surgery which represents the rationale for this study.
Method
Altmetric explorer was used to extract altmetrics and citation rates for articles published during 2018 in Plastic and Reconstructive Surgery (PRS), the Journal of Plastic, Reconstructive and Aesthetic Surgery, the Annals of Plastics Surgery and Plastic Surgery. Multivariable negative binomial regression was used to estimate the relationship between citations and predictors (presented as the incidence rate ratio, IRR with 95% confidence interval, CI).
Results
Overall, 1215 articles were captured. On average, articles published in PRS were cited nearly five times as often as articles published elsewhere (adjusted IRR 4.77 [95% CI 2.36, 9.62]). Overall, SoMe mentions were positively associated with citation rates (adjusted IRR 1.01 [95% CI 1.01, 1.1]); marginal analysis showed that 45 mentions translated to one extra citation.
Conclusions
Dissemination of plastic surgery research through SoMe channels are associated with significant improvements in short term citations rates.

Abstract
BACKGROUND The Centers for Disease Control and Prevention guidelines recommend naloxone for every high-dose opioid prescription; in 2018, only 1 naloxone prescription was dispensed for every 69 high-dose opioid prescriptions. In Virginia, strategies for creating awareness and availability include the REVIVE! training and the standing protocol for pharmacists to dispense naloxone. OBJECTIVES To evaluate if a proactive offer for counseling by pharmacists improves the percent change of patients who receive a prescription for naloxone nasal spray compared with the previous year's naloxone nasal spray fill history and to determine if the pharmacist's counseling affects a patient's confidence with opioid overdose and naloxone use. METHODS Prospective 4-month, interventional study in southwest Virginia conducted at 5 geographically similar large community chain pharmacies. A National Drug Code activity report within each store was used to identify patients, aged 18-64 years, filling opioid medication without naloxone. A pharmacist recommended naloxone to patients at the point of care. Patients accepting the recommendation for naloxone received pharmacist counseling from a standardized counseling script and by using a naloxone nasal spray demo kit. All eligible patients were provided a postintervention survey assessing their confidence with naloxone, if naloxone had been recommended before, and if they were picking up naloxone on the basis of the pharmacist's recommendation. Results were analyzed using univariate and bivariate analyses. RESULTS A total of 121 naloxone prescriptions were dispensed; an increase of 36% compared with the same period during the previous year. In total, 38 patients completed the postintervention survey. After receiving pharmacist counseling, patients indicated being very confident with administering naloxone correctly and for recognizing an opioid overdose, 73.9% and 65.2%, respectively. Of the patients who completed the survey, 60.5% received naloxone and accepted counseling from the pharmacist. CONCLUSION After pharmacist counseling, naloxone dispensing increased, and patients were confident with both administration and recognition.

Abstract
Background: Adherence, specifically to noninsulin diabetes medications, statins, and renin-angiotensin system antagonists (i.e. angiotensin-converting-enzyme inhibitors (ACEi), angiotensin II receptor blockers (ARBs), and aliskiren), is a measure tracked by the Centers for Medicare and Medicaid Services (CMS) to give Medicare Part D plans a star rating; pharmacies are impacted by these star ratings. The pharmacy is given a performance score based on the measure. Some pharmacies use a performance information management platform (PIMP) that allows pharmacies to better understand performance information to impact patient care. Objectives: (1) To evaluate if a monthly adherence monitoring and education service impacts the percentage of patientsadherent determined by pharmacy performance scores; (2) To determine patient satisfaction with the service in a large community pharmacy chain. Methods: A six-month prospective interventional pilot study including patients with a proportion of days covered (PDC) of less than 80% for oral diabetes or renin-angiotensin system antagonists (RASA) medications was conducted in two pharmacies of a large community pharmacy chain in Southwest Virginia. Using pharmacy internal data analytics and PIMP data, the percentage of patients who are adherent to oral diabetes or RASA medications was determined including the baseline PDC for each patient. At the start of the study, the standard of care in this large community chain pharmacy was to address adherence, follow-up in one month and every three months thereafter. In this study, pharmacists provided monthly telephonic adherence monitoring and education for a six-month period. Each session was scripted for medication adherence history, education and data collection. The pharmacist provided guidance and counseling based on how the patient answered the questions. Pharmacists gathered information about adherence patterns and behaviors using a 14 item Likert-scale and multiple choice-based questionnaire during the first session. After completion of the final adherence monitoring and education session, pharmacists gathered patient satisfaction information using an eight item Likert-scale questionnaire. At the end of the six-month period, using PIMP data, the percentage of patients adherent to oral diabetes or RASA medications was determined based on pharmacy performance scores. The data was analyzed using uni-variate and bi-variate statistics to determine if there was a difference in pharmacy performance scores from the pre-study analysis. The adherence patterns and behaviors, as well as patient satisfaction with the program was evaluated to determine factors influencing nonadherence. Results: A total of 55 patients were identified in two pharmacies, ten of which were excluded or declined involvement, leaving 45 enrolled in the adherence monitoring and education service. Of the 45 enrolled patients, ten completed the adherence patterns and behaviors questionnaire. About half of the patients were men (50.95%) with an average age of 71.17 years and taking an average of 6.55 prescription medications. All patients had Medicare Part D insurance and majority had a yearly income of less than $40,000. The average baseline PDC was 68.92. In pharmacy 1, the average performance score for oral diabetes medications trended down and the average performance score for hypertension medications trended up over the study period. In pharmacy 2, the average performance score for oral diabetes medications trended up and the average performance score in hypertension medications trended up over the study period. The adherence patterns and behaviors questionnaire revealed the majority of patients rarely forgot to take medications or run out of medications. Additionally, cost of medications did not seem to impact adherence and majority of patients knew the names and indications of their medications. Only one patient completed the patient satisfaction survey. Conclusions: An adherence monitoring and education service had mixed results in improving patient adherence and pharmacy performance scores. Only one patient completed the satisfaction survey, thus no conclusions can be made regarding patient satisfaction of the program. More research needs to be done regarding telephonic adherence programs.

Abstract
OBJECTIVE To compare community-based pharmacy medication errors before and after a one-hour live interactive training session for both pharmacists and technicians. METHODS A one group pre-post intervention design study was conducted in 20 community-based pharmacies in a district of a large national community pharmacy chain. A one-hour live, interactive session was developed based on incident reports and medication error trends including medication error definition, ways in which medication errors occur, strategies for mitigating errors, information about human error, and methods and habits to improve patient safety. At least 50% of full-time staff for each of the 20 pharmacies were required to attend a training session between December 1, 2017-January 15, 2018. Participants completed a demographics survey documenting gender, age, credentials, number of years of experience, and years of service with the company. Pharmacies were categorized as low, medium or high volume based on prescription count. Medication errors were compared six months pre- and post-live education session. Data were analyzed using SAS version 9.4. RESULTS One hundred and thirty- five errors and 111 errors were reported pre-and post-live training (mean 6.85 and 5.55, p < 0.301), respectively. Nine pharmacies were low, eight medium, and three high volume with the mean number of medication errors reported pre- and post-live training; low 4.33 vs 4.11 p<0.478, medium 9.37 vs 6.87 p<0.443, and high 7.66 vs 6.33 p<0.593, respectively. Sixty pharmacy staff (34 pharmacists, 26 technicians) attended one of the live training sessions; 73% female; most frequently reported age range 35-50 years; 23 Doctor of Pharmacy, 11 Bachelor of Science in Pharmacy, and 26 Certified Technician; and average number of years' experience was 13.6 and average service with the company was 8.6 years. CONCLUSIONS A live training session for both pharmacists and technicians did not significantly decrease medication errors, but could be incorporated as an element of a medication safety program. It should be considered for implementation in other districts of this large national pharmacy chain as a part of an improved patient safety effort.

Abstract
BACKGROUND This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery. METHODS This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery. RESULTS A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498). CONCLUSION There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

Abstract
PURPOSE Metastatic renal cell carcinoma (mRCC) represents a significant and rising burden of disease, with rapidly evolving treatment modalities. The role of cytoreductive nephrectomy (CN) is controversial in this setting. As such, London Cancer has pursued a multidisciplinary team (MDT) approach when assessing suitability for surgery. METHODS A retrospective analysis of treatment-naive synchronous mRCC patients, managed via a renal-specialist MDT, was conducted between January 2015 and December 2018. An MDT selection algorithm for CN-using the International Metastatic Renal Cell Carcinoma Database Consortium score (IMDC), performance status and metastatic disease burden-was developed. RESULTS 87 treatment-naive synchronous mRCC patients received either CN (n = 18), Systemic therapy (ST) alone (n = 43) or Best supportive care (BSC) (n = 26). Progression free survival (PFS) and overall survival (OS) were assessed. 51% and 39% were IMDC intermediate and poor risk. Median PFS was 28.6 months and 4.5 months in the CN group and ST alone group, respectively, Hazard Ratio for death was 3.63 [(95% CI 1.68-7.83) p < 0.05]. OS remains immature for the CN group, but a median OS of 12.8 months was observed in the ST group and 5.0 months for BSC. 1-year OS rate for CN, ST and BSC groups was 77.8%, 55.8% and 23.10%, respectively. CONCLUSION These findings describe outcomes of an unselected series of patients treated via an MDT-driven, protocolised treatment pathway. MDT pathway-based decision making may improve patient selection for CN. Further research is needed to evaluate the role of CN amongst a growing landscape of treatment strategies, including immune checkpoint inhibitors and combination therapies. Multi-disciplinary team, pathway-based treatment strategy may improve patient selection for cytoreductive nephrectomy in patients with metastatic renal cell carcinoma.

Abstract
Abstract
A multilaboratory collaborative study was conducted to compare the Assurance GDS™ for E. coli O157:H7 method and the reference culture methods for the detection of E. coli O157:H7 in orange juice, raw ground beef, and fresh lettuce. A separate companion assay, the Assurance GDS for Shigatoxin Genes method was also evaluated with the same test portions. Fifteen laboratories participated in the study. A Chi square analysis of each of the 3 food types at the high, low, and uninoculated control levels was performed. For all foods, the Assurance GDS for E. coli O157:H7 method and the Assurance GDS for Shigatoxin Genes method were equivalent to or better than the reference methods.

Abstract
Abstract
BACKGROUND: Women with TNBC who do not achieve a pathologic complete response (pCR) with preoperative (preop) chemotherapy have a high risk of recurrence and death from BC. Immunotherapy is an attractive strategy as human BCs can be immunogenic, and enhancing the immune effector function may augment the cytotoxic effects of standard therapies.
CLINICAL TRIAL: Following IRB-approved informed consent, 10 pts with locally advanced TNBC received preop dose-dense doxorubicin/cyclophosphamide (AC) followed by paclitaxel and carboplatin (TCb) chemotherapy, combined with antigen-loaded (TNBC antigens: Cyclin B1, WT1, and control viral antigens: CEF) autologous monocyte-derived DC vaccinations administered intratumorally and subcutaneously. DCs were generated with GM-CSF and type I interferon, loaded with antigen in the form of long peptides and activated with innate ligands (LPS and Clo75) and CD40 ligand. Vaccines were given at 4 time points prior to definitive surgery, and 3 times post-surgery, pre- and post-radiation therapy (RT). Safety was the primary study endpoint, and pCR rate in breast and axilla was a secondary endpoint. Correlative studies included assessment of immune response via ELISpot and transcriptional profiling of blood samples collected over time.
RESULTS: All pts received the 4 vaccines during preop chemotherapy, and 7/10 received all 7 vaccines. At the time of definitive surgery, 4 pts achieved a pCR, 3 pts had macroscopic residual disease in the breast and axillary lymph nodes, and 3 pts had residual cancer burden scores of 1. As of June 1, 2017, all pts have been in follow-up for at least 1 year s/p completion of all vaccines, and 7/10 patients have no evidence of disease.
To assess immune signatures with IFN-γ-ELISpot, PBMCs from baseline (BL) and several time points during vaccine treatment were cultured with control peptides or with peptide libraries covering vaccine antigens. Using a linear mixed model to account for repeated and missing observations we found statistically significant (α = 0.05) increases in Cyclin B1, WT1, and CEF ELISpots in at least 1 time point post-DC vaccination and in follow-up. Compared to BL, Cyclin B1 and WT1 increased at 3 day pre-RT in 8/10 and 7/10 pts, respectively. To assess transcriptional signatures, a linear mixed model was utilized to determine statistically significant differences in fold-change over time compared to the BL and healthy controls. Modular analysis of differentially expressed transcripts at BL revealed downregulation of transcripts related to the monocyte lineage in 7/10 pts. Longitudinal analysis revealed profound transcriptional changes during AC with downregulation of lymphocyte modules and upregulation of innate and inflammation modules. While the latter ones have normalized during TCb and follow-up, T cell module remained substantially downregulated throughout treatment and follow-up.
CONCLUSIONS: Combination of preop chemotherapy and intratumoral and subcutaneous autologous DC vaccination is safe in locally advanced TNBC pts and is linked with profound changes in immune transcription signatures and with expansion of antigen-specific immune responses that can be detected in IFN-γ ELISpot.

Abstract
The interaction between TiO2 nanoparticles (NPs) and inflammatory cytokines, including CXCL8, a clinically relevant pro-inflammatory chemokine was investigated. TiO2 is present in tissues adjacent to failing implanted Ti (titanium) devices. TiO2 NPs were shown to bind to CXCL8 in vitro, causing perturbation of quantification of CXCL8 by ELISA, in both simple and complex protein panels, in a dose-dependent manner. Binding between TiO2 NPs and CXCL8 was demonstrated by protein gel electrophoresis. TiO2 NPs were also shown to inactivate the chemoattractant property of CXCL8 in a dose-dependent manner, suggesting that the binding between TiO2 NPs and CXCL8 is likely to be clinically relevant. The results of this study disputed the applicability of detection of CXCL8 by ELISA in systems where TiO2 NPs were present. Clinically, the disruption of chemotaxis of neutrophils in response to CXCL8 in the presence of TiO2 might mean a hampered immune response to inflammation in tissues containing TiO2 NPs.

Abstract
In this work, trend estimates are used as indicators to compare the multi-annual variability of different satellite chlorophyll-a (Chla) data and to assess the fitness-for-purpose of multi-mission Chla products as climate data records (CDR). Under the assumption that single-mission products are free from spurious temporal artifacts and can be used as benchmark time series, multi-mission CDRs should reproduce the main trend patterns observed by single-mission series when computed over their respective periods. This study introduces and applies quantitative metrics to compare trend distributions from different data records. First, contingency matrices compare the trend diagnostics associated with two satellite products when expressed in binary categories such as existence, significance and signs of trends. Contingency matrices can be further summarized by metrics such as Cohen's κ index that rates the overall agreement between the two distributions of diagnostics. A more quantitative measure of the discrepancies between trends is provided by the distributions of differences between trend slopes. Thirdly, maps of the level of significance P of a t-test quantifying the degree to which two trend estimates differ provide a statistical, spatially-resolved, evaluation. The proposed methodology is applied to the multi-mission Ocean Colour-Climate Change Initiative (OC-CCI) Chla data. The agreement between trend distributions associated with OC-CCI data and single-mission products usually appears as good as when single-mission products are compared. As the period of analysis is extended beyond 2012 to 2015, the level of agreement tends to be degraded, which might be at least partly due to the aging of the MODIS sensor on-board Aqua. On the other hand, the trends displayed by the OC-CCI series over the short period 2012-2015 are very consistent with those observed with VIIRS. These results overall suggest that the OC-CCI Chla data can be used for multi-annual time series analysis (including trend detection), but with some caution required if recent years are included, particularly in the central tropical Pacific. The study also recalls the challenges associated with creating a multi-mission ocean color data record suitable for climate research.

Abstract
OBJECTIVES To describe the 'Resuscitation with Pre-HospItaL bLood products' trial (RePHILL) - a multi-centre randomised controlled trial of pre-hospital blood product (PHBP) administration vs standard care for traumatic haemorrhage. BACKGROUND PHBP are increasingly used for pre-hospital trauma resuscitation despite a lack of robust evidence demonstrating superiority over crystalloids. Provision of PHBP carries additional logistical and regulatory implications, and requires a sustainable supply of universal blood components. METHODS RePHILL is a multi-centre, two-arm, parallel group, open-label, phase III randomised controlled trial currently underway in the UK. Patients attended by a pre-hospital emergency medical team, with traumatic injury and hypotension (systolic blood pressure <90 mmHg or absent radial pulse) believed to be due to traumatic haemorrhage are eligible. Exclusion criteria include age <16 years, blood product receipt on scene prior to randomisation, Advanced Medical Directive forbidding blood product administration, pregnancy, isolated head injury and prisoners. A total of 490 patients will be recruited in a 1 : 1 ratio to receive either the intervention (up to two units of red blood cells and two units of lyophilised plasma) or the control (up to four boluses of 250 mL 0.9% saline). The primary outcome measure is a composite of failure to achieve lactate clearance of ≥20%/h over the first 2 hours after randomisation and all-cause mortality between recruitment and discharge from the primary receiving facility to non-acute care. Secondary outcomes include pre-hospital time, coagulation indices, in-hospital transfusion requirements and morbidity. RESULTS Pilot study recruitment began in December 2016. Approval to proceed to the main trial was received in June 2017. Recruitment is expected to continue until 2020. CONCLUSIONS RePHILL will provide high-quality evidence regarding the efficacy and safety of PHBP resuscitation for trauma.

Abstract
Technosphere insulin (TI), an inhaled insulin with a fast onset of action, provides a novel option for the control of prandial glucose. A euglycemic glucose clamp study was performed to compare the effects of TI and regular human insulin (RHI) on the induced glucose infusion rate (GIR) in healthy volunteers. Generation of a dose–response relationship between insulin dose and effect (expressed as AUC of GIR) was not possible from the clinical data directly. The GIR recording time was too short to capture the full effect and higher doses were not tested. Thus, a pharmacokinetic‐GIR model was developed to simulate GIR for a sufficient time window of 20 h and for higher doses. A dose–response model was then generated from the simulated GIR profiles. The resulting model provides an ED50 for TI that is 5‐fold higher than for RHI, a ratio that can be used as conversion factor for equivalent doses of RHI and TI.

Abstract
BACKGROUND Enhanced recovery programmes improve outcomes in surgery, but their implementation after upper gastrointestinal resection has been limited. The aim of this study was to compare short-term outcomes for patients undergoing oesophagogastric surgery in an enhanced recovery programme (EROS). METHODS EROS was developed after a multidisciplinary meeting by multiple rounds of revision. EROS was applied to all patients undergoing major upper GI resection at a university teaching hospital in the UK from 20/9/13, with data reviewed at 18/09/15. EROS was assessed to identify predictors for compliance. RESULTS One hundred six patients underwent major upper GI resection including 81 oesophagectomies, 24 gastrectomies and 1 colonic interposition graft. Major complications (Clavien Dindo ≥3) occurred in 12 patients with 1 in-hospital death. Thirty-five patients (44%) were discharged on target day 8 of the EROS programme. Age and complications were independently associated with missing this discharge target. CONCLUSION Enhanced recovery is feasible and safe after major upper gastrointestinal surgery.

Abstract
Philp (2003) outlined the fundamental role that occupational therapists could have in implementing the National Service Framework (NSF) for Older People and reforming services for older people (Department of Health 2001). A research project was undertaken, which aimed to investigate the views of occupational therapists about the implementation of the policy in order to identify the key areas and issues that have had an impact on practice. The research design was qualitative and took the form of focus groups. The focus group data were analysed using a long-table analysis method (Krueger and Casey 2000), which identified five key themes: a raised profile of older people's services, a changing delivery of services, a revisiting of occupational therapy core skills, assessment and resource allocation. The emerging themes suggested that the NSF for Older People has had an impact on the practice of the occupational therapists involved in the focus groups.

Abstract
AIMS To develop and evaluate a loop-mediated isothermal amplification (LAMP) assay for Xanthomonas campestris pathovar musacearum (Xcm), the causal agent of banana Xanthomonas wilt, a major disease of banana in Africa. METHODS AND RESULTS LAMP primers were designed to the general secretion pathway protein D gene and tested against 17 isolates of Xcm encompassing the known genetic and geographic diversity of the bacterium and all isolates were detected. Seventeen other Xanthomonas isolates, including closely related Xanthomonas vasicola, other bacterial pathogens/endophytes of Musa and two healthy Musa varieties gave negative results with the LAMP assay. The assay showed good sensitivity, detecting as little as 51 fg of Xcm DNA, a greater level of sensitivity than that of an Xcm PCR assay. Amplification with the LAMP assay was very rapid, typically within 9 min from bacterial cultures. Symptomatic field samples of Musa from Uganda were tested and all produced amplification in less than 13 min. CONCLUSIONS The LAMP assay provides rapid, sensitive detection of the pathogen that is ideally suited for deployment in laboratories with basic facilities and in-field situations. SIGNIFICANCE AND IMPACT OF THE STUDY This is the first LAMP assay for Xcm which provides a significant improvement compared to existing diagnostics.

Abstract
It is important for nurses to have positive attitudes towards patient care if good quality care is to be provided. This study explored nurses’ attitudes towards providing care to patients in one rural district hospital in KwaZulu-Natal from the perspective of the nurses themselves, and from the patients’ perspective. We conducted an explorative qualitative study. Thirteen focus group discussions were conducted with professional/enrolled nurses, enrolled nurse assistants and patients. Discussions were audio-recorded, transcribed and analysed using a thematic approach. While some nurses were passionate about nursing for altruistic reasons, many nurses said they actively disliked nursing. Reasons were staff shortages, high patient loads, absenteeism, and poor interpersonal communication. Both nurses and patients reported incidences of poor patient care and even willful neglect of patients’ basic care. Nurses blamed sub-standard nursing care on the attitudes of patients or patients’ relatives, as well as on lack of management support. Patients described both positive and negative experiences of nursing care received. Poor attitudes of nurses, resulting in poor patient care, could severely undermine the ability of the health system to provide quality care and improve outcomes for patients. It is recommended that all hospitals assess nurses’ attitudes regularly to ensure that patient care is not compromised.

Abstract
Abstract
COX2 has been implicated in breast tumorigenesis, tumour proliferation & invasion. The role of COX2 in carcinogenesis is thought to be related to its abilities to increase production of prostaglandins, convert pro-carcinogens to carcinogens, inhibit apoptosis, promote angiogenesis, modulate inflammation & immune function & increase tumour cell invasiveness. COX2 inhibition may synergise with aromatase inhibition in controlling endocrine responsive breast cancer. The COX2 product prostaglandin E2 (PGE2) & cytokines such as interleukin-6 (IL6) can up regulate aromatase expression suggesting that aromatase inhibition may be more effective in combination with a COX2 inhibitor. There may be additional COX2 mediated anticancer activity. The hypothesis addressed is that activity of aromatase inhibitors(AI) as neoadjuvant endocrine therapy for early breast cancer may be enhanced by the addition of a COX2 inhibitor.
TRIAL OBJECTIVES
To determine whether the activity of AIs as neo-adjuvant endocrine therapy for ER positive breast cancer in postmenopausal women may be enhanced by the addition of the selective COX2 inhibitor celecoxib.
TRIAL DESIGN
Prospective phase III multicentre randomised trial. Patients were randomised to receive 16 weeks of exemestane 25 mg daily or letrozole 2.5 mg daily (open label) and celecoxib 400 mg twice daily or matched placebo (double blinded). Translational research tumour samples were collected before, during & after therapy.
KEY ELIGIBILITY CRITERIA
Post menopausal, ER positive, invasive cancer, 2cms or greater with calipers & visible on USS.
PRIMARY OUTCOME MEASURE
Objective clinical response to neoadjuvant treatment by RECIST criteria.
RESULTS
Primary Outcome; Response to treatment has been calculated for 266 patients (Table 1). Response rate was 73% in the celecoxib arm & 55% in the placebo arm (p=0.0022). The response rates 4 arm comparison are shown in Table 2. After adjustment for AI effect the significant difference in response rates remained (p=0.0023); the difference in response rates was greater in the exemestane treated group (29%) compared to the letrozole group (7%) although heterogeneity between AI arms was statistically non-significant (p=0.06).

Abstract
In New Zealand there has been a long association of Phytophthora diseases in forests, nurseries, remnant plantings and horticultural crops. However, new Phytophthora diseases of trees have recently emerged. Genome sequencing has been performed for 12 Phytophthora isolates, from six species: Phytophthora pluvialis, Phytophthora kernoviae, Phytophthora cinnamomi, Phytophthora agathidicida, Phytophthora multivora and Phytophthora taxon Totara. These sequences will enable comparative analyses to identify potential virulence strategies and ultimately facilitate better control strategies. This Whole Genome Shotgun data have been deposited in DDBJ/ENA/GenBank under the accession numbers LGTT00000000, LGTU00000000, JPWV00000000, JPWU00000000, LGSK00000000, LGSJ00000000, LGTR00000000, LGTS00000000, LGSM00000000, LGSL00000000, LGSO00000000, and LGSN00000000.

Abstract
Xanthomonas campestris pv. musacearum (Xcm) is the causal agent of banana xanthomonas wilt, a major threat to banana production in eastern and central Africa. The pathogen is present in very high levels within infected plants and can be transmitted by a broad range of mechanisms; therefore early specific detection is vital for effective disease management. In this study, a polyclonal antibody (pAb) was developed and deployed in a lateral flow device (LFD) format to allow rapid in-field detection of Xcm. Published Xcm PCR assays were also independently assessed: only two assays gave specific amplification of Xcm, whilst others cross-reacted with non-target Xanthomonas species. Pure cultures of Xcm were used to immunize a rabbit, the IgG antibodies purified from the serum and the resulting polyclonal antibodies tested using ELISA and LFD. Testing against a wide range of bacterial species showed the pAb detected all strains of Xcm, representing isolates from seven countries and the known genetic diversity of Xcm. The pAb also detected the closely related Xanthomonas axonopodis pv. vasculorum (Xav), primarily a sugarcane pathogen. Detection was successful in both naturally and experimentally infected banana plants, and the LFD limit of detection was 105 cells mL-1. Whilst the pAb is not fully specific for Xcm, Xav has never been found in banana. Therefore the LFD can be used as a first-line screening tool to detect Xcm in the field. Testing by LFD requires no equipment, can be performed by non-scientists and is cost-effective. Therefore this LFD provides a vital tool to aid in the management and control of Xcm.

Abstract
Symptoms of attention deficit-hyperactivity disorder (ADHD), particularly inattention, and impairments in executive functioning have been reported in early and continuously treated children, adolescents, and adults with phenylketonuria (PKU). In addition, higher blood phenylalanine (Phe) levels have been correlated with the presence of ADHD symptoms and executive functioning impairment. The placebo-controlled PKU ASCEND study evaluated the effects of sapropterin therapy on PKU-associated symptoms of ADHD and executive and global functioning in individuals who had a therapeutic blood Phe response to sapropterin therapy. The presence of ADHD inattentive symptoms and executive functioning deficits was confirmed in this large cohort of 206 children and adults with PKU, of whom 118 responded to sapropterin therapy. In the 38 individuals with sapropterin-responsive PKU and ADHD symptoms at baseline, sapropterin therapy resulted in a significant improvement in ADHD inattentive symptoms in the first 4 weeks of treatment, and improvements were maintained throughout the 26 weeks of treatment. Sapropterin was well-tolerated with a favorable safety profile. The improvements in ADHD inattentive symptoms and aspects of executive functioning in response to sapropterin therapy noted in a large cohort of individuals with PKU indicate that these symptoms are potentially reversible when blood Phe levels are reduced.

Abstract
Background: Since there is no disease-specific instrument for measuring quality-of-life (QOL) in Ostomy patients in Persian language. Aim: This study was designed to translate and evaluate the validity and reliability of City of Hope-quality of life-Ostomy questionnaire (COH-QOL-Ostomy questionnaire). Subjects and Methods: This study was designed as cross-sectional study. Reliability of the subscales and the summary scores were demonstrated by intra-class correlation coefficients. Pearson's correlations of an item with its own scale and other scales were calculated to evaluated convergent and discriminant validity. Clinical validity was also evaluated by known-group comparisons. Results: Cronbach's alpha coefficient for all subscales was about 0.70 or higher. Results of interscale correlation were satisfactory and each subscale only measured a single and specified trait. All subscales met the standards of convergent and discriminant validity. Known group comparison analysis showed significant differences in social and spiritual well-being. Conclusion: The findings confirmed the reliability and validity of Persian version of COH-QOL-Ostomy questionnaire. The instrument was also well received by the Iranian patients. It can be considered as a valuable instrument to assess the different aspects of health related quality-of-life in Ostomy patients and used in clinical research in the future.

Abstract
Plant cell wall modification is a critical component in stress responses. Endo-1,4-β-glucanases (EGs) take part in cell wall editing processes, e.g. elongation, ripening and abscission. Here we studied the infection response of Solanum lycopersicum and Arabidopsis thaliana with impaired EGs. Transgenic TomCel1 and TomCel2 tomato antisense plants challenged with Pseudomonas syringae showed higher susceptibility, callose priming and increased jasmonic acid pathway marker gene expression. These two EGs could be resistance factors and may act as negative regulators of callose deposition, probably by interfering with the defence-signalling network. A study of a set of Arabidopsis EG T-DNA insertion mutants challenged with P. syringae and Botrytis cinerea revealed that the lack of other EGs interferes with infection phenotype, callose deposition, expression of signalling pathway marker genes and hormonal balance. We conclude that a lack of EGs could alter plant response to pathogens by modifying the properties of the cell wall and/or interfering with signalling pathways, contributing to generate the appropriate signalling outcomes. Analysis of microarray data demonstrates that EGs are differentially expressed upon many different plant-pathogen challenges, hormone treatments and many abiotic stresses. We found some Arabidopsis EG mutants with increased tolerance to osmotic and salt stress. Our results show that impairing EGs can alter plant-pathogen interactions and may contribute to appropriate signalling outcomes in many different biotic and abiotic plant stress responses.

Abstract
Ceriporiopsis subvermispora oxalate oxidase (CsOxOx) is the first bicupin enzyme identified that catalyzes manganese-dependent oxidation of oxalate. In previous work, we have shown that the dominant contribution to catalysis comes from the monoprotonated form of oxalate binding to a form of the enzyme in which an active site carboxylic acid residue must be unprotonated. CsOxOx shares greatest sequence homology with bicupin microbial oxalate decarboxylases (OxDC) and the 241-244DASN region of the N-terminal Mn binding domain of CsOxOx is analogous to the lid region of OxDC that has been shown to determine reaction specificity. We have prepared a series of CsOxOx mutants to probe this region and to identify the carboxylate residue implicated in catalysis. The pH profile of the D241A CsOxOx mutant suggests that the protonation state of aspartic acid 241 is mechanistically significant and that catalysis takes place at the N-terminal Mn binding site. The observation that the D241S CsOxOx mutation eliminates Mn binding to both the N- and C- terminal Mn binding sites suggests that both sites must be intact for Mn incorporation into either site. The introduction of a proton donor into the N-terminal Mn binding site (CsOxOx A242E mutant) does not affect reaction specificity. Mutation of conserved arginine residues further support that catalysis takes place at the N-terminal Mn binding site and that both sites must be intact for Mn incorporation into either site.

Abstract
BACKGROUND ROSE-010, a Glucagon-Like Peptide-1 (GLP-1) analog, reduces gastrointestinal motility and relieves acute pain in patients with irritable bowel syndrome (IBS). The rat small bowel migrating myoelectric complex (MMC) is a reliable model of pharmacological effects on gastrointestinal motility. Accordingly, we investigated whether ROSE-010 works through GLP-1 receptors in gut musculature and its effectiveness when administered by pulmonary inhalation. MATERIALS AND METHODS Rats were implanted with bipolar electrodes at 5, 15 and 25 cm distal to pylorus and myoelectric activity was recorded. First, intravenous or subcutaneous injections of ROSE-010 or GLP-1 (1, 10, 100 μg/kg) with or without the GLP-1 receptor blocker exendin(9-39)amide (300 μg/kg·h), were studied. Second, ROSE-010 (100, 200 μg/kg) Technosphere® powder was studied by inhalation. RESULTS The baseline MMC cycle length was 17.5±0.8 min. GLP-1 and ROSE-010, administered intravenously or subcutaneously, significantly inhibited myoelectric activity and prolonged MMC cycling; 100 μg/kg completely inhibited spiking activity for 49.1±4.2 and 73.3±7.7 min, while the MMC cycle length increased to 131.1±11.4 and 149.3±15.5 min, respectively. Effects of both drugs were inhibited by exendin(9-39)amide. Insufflation of ROSE-010 (100, 200 μg/kg) powder formulation totally inhibited myoelectric spiking for 52.6±5.8 and 70.1±5.4 min, and increased MMC cycle length to 102.6±18.3 and 105.9±9.5 min, respectively. CONCLUSIONS Pulmonary delivery of ROSE-010 inhibits gut motility through the GLP-1R similar to natural GLP-1. ROSE-010 causes receptor-mediated inhibition of MMC comparable to that of intravenous or subcutaneous administration. This suggests that ROSE-010 administered as a Technosphere® inhalation powder has potential in IBS pain management and treatment.
