Abstract
The recent global resurgence of severe infections caused by the Group A streptococcus (GAS) pathogen, Streptococcus pyogenes, has focused attention on this microbial pathogen, which produces an array of virulence factors, such as the pore-forming toxin, streptolysin O (SOT). Importantly, the interactions of SOT with human neutrophils (PMN), are not well understood. The current study was designed to investigate the effects of pretreatment of isolated human PMN with purified SOT on several pro-inflammatory activities, including generation of reactive oxygen species (ROS), degranulation (elastase release), influx of extracellular calcium (Ca2+) and release of extracellular DNA (NETosis), using chemiluminescence, spectrophotometric and fluorimetric procedures, respectively. Exposure of PMN to SOT alone caused modest production of ROS and elastase release, while pretreatment with the toxin caused significant augmentation of chemoattractant (fMLP)-activated ROS generation and release of elastase by activated PMN. These effects of treatment of PMN with SOT were associated with both a marked and sustained elevation of cytosolic Ca2+concentrations and significant increases in the concentrations of extracellular DNA, indicative of NETosis. The current study has identified a potential role for SOT in augmenting the Ca2+-dependent pro-inflammatory interactions of PMN, which, if operative in a clinical setting, may contribute to hyper-activation of PMN and GAS-mediated tissue injury.

Abstract
BACKGROUND Early identification and control of hypertension is critical to reducing cardiovascular disease events and death. U.S. Preventive Services Task Force guidelines recommend health care professionals screen all adults for hypertension, yet 1 in 4 adults with hypertension are unaware of their condition. This gap between guidelines and clinical practices highlights an important opportunity to improve blood pressure (BP) screening and hypertension diagnosis, including measurement outside of clinic settings. To identify targets for future diagnostic interventions, we sought to understand primary care physicians' (PCPs) beliefs and practices regarding use of common forms of BP measurement. METHODS Study participants were PCPs (N = 27) who had patients enrolled in the BP-CHECK trial. The trial compared the accuracy of 24-h ambulatory BP monitoring (ABPM) to: 1) clinic-based monitoring, 2) home BP monitoring (HBPM), or 3) use of a BP kiosk in clinics or pharmacies. Physicians were interviewed by phone and compensated for their participation. Interviews were recorded, transcribed, and analyzed using a template analysis approach. RESULTS Overall, PCPs preferred and trusted clinic BP measurement for diagnosing hypertension, particularly when measured with a manual sphygmomanometer. Concerns with HBPM included the belief that patients did not follow protocols for rest and body positioning at home, that home machines were not accurate, that home BPs could not be entered into the medical record, and that HBPM would make some patients anxious. Issues regarding kiosk measurement included beliefs that the public setting created stress for patients, that patients did not follow resting protocols when using kiosks, and concerns about the maintenance of these machines. ABPM was recognized as highly accurate but was not perceived as accessible. Additionally, some PCPs found it challenging to interpret the multiple readings generated by ABPM and HBPM, especially when these readings differed from clinic BPs. CONCLUSIONS Our findings suggest that both additional physician education and training and investments in equipment and system-level processes are needed to increase the acceptance and utilization of out of office BP measurement for identification and treatment of hypertension. These changes are needed to improve ensure everyone in the U.S receive optimal care for hypertension. TRIAL REGISTRATION ClinicalTrials.gov NCT03130257 . Initial registration date: 4/21/2017.

Abstract
BACKGROUND The US Preventive Services Task Force recommends blood pressure (BP) measurements using 24-h ambulatory monitoring (ABPM) or home BP monitoring before making a new hypertension diagnosis. OBJECTIVE Compare clinic-, home-, and kiosk-based BP measurement to ABPM for diagnosing hypertension. DESIGN, SETTING, AND PARTICIPANTS Diagnostic study in 12 Washington State primary care centers, with participants aged 18-85 years without diagnosed hypertension or prescribed antihypertensive medications, with elevated BP in clinic. INTERVENTIONS Randomization into one of three diagnostic regimens: (1) clinic (usual care follow-up BPs); (2) home (duplicate BPs twice daily for 5 days); or (3) kiosk (triplicate BPs on 3 days). All participants completed ABPM at 3 weeks. MAIN MEASURES Primary outcome was difference between ABPM daytime and clinic, home, and kiosk mean systolic BP. Differences in diastolic BP, sensitivity, and specificity were secondary outcomes. KEY RESULTS Five hundred ten participants (mean age 58.7 years, 80.2% white) with 434 (85.1%) included in primary analyses. Compared to daytime ABPM, adjusted mean differences in systolic BP were clinic (-4.7mmHg [95% confidence interval -7.3, -2.2]; P<.001); home (-0.1mmHg [-1.6, 1.5];P=.92); and kiosk (9.5mmHg [7.5, 11.6];P<.001). Differences for diastolic BP were clinic (-7.2mmHg [-8.8, -5.5]; P<.001); home (-0.4mmHg [-1.4, 0.7];P=.52); and kiosk (5.0mmHg [3.8, 6.2]; P<.001). Sensitivities for clinic, home, and kiosk compared to ABPM were 31.1% (95% confidence interval, 22.9, 40.6), 82.2% (73.8, 88.4), and 96.0% (90.0, 98.5), and specificities 79.5% (64.0, 89.4), 53.3% (38.9, 67.2), and 28.2% (16.4, 44.1), respectively. LIMITATIONS Single health care organization and limited race/ethnicity representation. CONCLUSIONS Compared to ABPM, mean BP was significantly lower for clinic, significantly higher for kiosk, and without significant differences for home. Clinic BP measurements had low sensitivity for detecting hypertension. Findings support utility of home BP monitoring for making a new diagnosis of hypertension.

Abstract
Introduction:
Despite recommendations to use out of office blood pressure (BP) to confirm diagnosis of hypertension, there is little robust evidence on the acceptability of different methods for confirming hypertension. Most evaluations have involved small observational studies and have not compared measurement methods. The Blood Pressure Checks for Diagnosing Hypertension trial (BP-CHECK) trial compared the acceptability and adherence of clinic, home, kiosk and 24-hour ambulatory monitoring (ABPM) among adults with elevated BP who had not been diagnosed with hypertension.
Methods:
Adults presenting to Kaiser Permanente Washington primary care clinics with elevated BP but who did not have a hypertension diagnosis, were randomized to one of three arms: office, home and kiosk. ABPM was also conducted on all participants. Acceptability of each method to patients was measured using a validated questionnaire to calculate an overall score. Differences in mean acceptability by randomization arms and ABPM were calculated using linear regression models and Generalized Estimating Equations. Adherence was calculated as the proportion of participants completing their BP testing protocols and compared using chi-square tests.
Results:
A total of 510 individuals were randomized, with mean age 59 years, 80% white, 51% male, with mean BP of 150/88. The overall acceptability score was highest (i.e. most acceptable) for home (mean 6.2, SD 0.7) and lowest (i.e. least acceptable) for ABPM (mean 5.0, SD 1.0). Scores were intermediate for clinic (5.5, SD 1.1) and kiosk (5.4, SD 1.0) groups. Acceptability was significantly higher for all three intervention arms compared to ABPM. Adherence to the minimum number of BP readings pre-specified in the study protocol was higher for home (90.6%) and clinic (87.2%) groups than for the kiosk group (67.9%).
Conclusions:
Home BP measurement was the most acceptable method for diagnosing hypertension followed by measurement in the clinic or at kiosks, with ABPM the least acceptable, due to its discomfort, disturbance to sleep and to everyday activities. Although ABPM is considered the gold standard for confirming elevated BP, patients find home BP more acceptable.

Abstract
Context:
The US Preventive Services Task Force recommends out-of-office blood pressure (BP) measurement before making a new diagnosis of hypertension, using 24-hour ambulatory (ABPM) or home BP monitoring. However, this approach is not common in routine practice.
Objective:
To evaluate provider knowledge, beliefs, and practices about BP diagnostic tests
Methods:
The setting was 10 primary care medical centers in a single health care system. E-mails with a link to a survey were sent to 420 providers, with 282 (67%) responding, including 102 medical assistants (MA), 28 licensed practical nurses (LPN), 33 registered nurses (RN), 86 primary care physicians (physician), and 33 advanced practitioners (AP). Outcomes were a descriptive analysis of provider BP measurement and hypertension diagnosis knowledge, beliefs, and practices.
Results:
Most providers (78.8%) believed that BP measured manually with a stethoscope and ABPM as very or highly accurate way to measure BP when making a new diagnosis of hypertension. In contrast, most providers did not believe that automated clinic BPs, home BP, or kiosk BP measurements were very or highly accurate. Almost all providers reported that they always or almost always relied on clinic BP measurements in making a new diagnosis of hypertension (95.7%), but the majority of physician/APs would prefer using ABPM (60.5%) if it was readily available. Providers were mixed as to whether patients received home BP training and whether home BP monitors were checked for accuracy. Physician/APs reported varying home BP schedules with no schedule the most common response (37.3%), followed by 14 days (19.1%), and 7 days (10.9%). Almost all physicians/APs reported using a clinic BP threshold of 140/90 mmHg for making a new diagnosis of, but a few reported 130/80 mmHg. Very few physician/APs reported guideline concordant home or ABPM diagnostic thresholds, with 140/90 mmHg the most common response.
Conclusion:
In our study providers did not report following evidence-based guidelines for making a new diagnosis of hypertension, and appeared to have substantial gaps in knowledge, beliefs, and use of recommended practices. Interventions to increase use of evidence-based practices for diagnosing hypertension are needed.

Abstract
BACKGROUND The US Preventive Services Task Force recommends out-of-office blood pressure (BPs) before making a new diagnosis of hypertension, using 24-h ambulatory (ABPM) or home BP monitoring (HBPM), however this is not common in routine clinical practice. Blood Pressure Checks and Diagnosing Hypertension (BP-CHECK) is a randomized controlled diagnostic study assessing the comparability and acceptability of clinic, home, and kiosk-based BP monitoring to ABPM for diagnosing hypertension. Stakeholders including patients, providers, policy makers, and researchers informed the study design and protocols. METHODS Adults aged 18-85 without diagnosed hypertension and on no hypertension medication with elevated BPs in clinic and at the baseline research visit are randomized to one of 3 regimens for diagnosing hypertension: (1) clinic BPs, (2) home BPs, or (3) kiosk BPs; all participants subsequently complete ABPM. The primary outcomes are the comparability (with daytime ABPM mean systolic and diastolic BP as the reference standard) and acceptability (e.g., adherence to, patient-reported outcomes) of each method compared to ABPM. Longer-term outcomes are assessed at 6-months including: patient-reported outcomes, primary care providers' diagnosis of hypertension; and BP control. We report challenges experienced and our response to these. RESULTS Enrollment began in May of 2017 with a target of randomizing 510 participants. BP thresholds for diagnosing hypertension in the US changed after the trial started. We discuss the stakeholder process used to assess and respond to these changes. CONCLUSION AND PUBLIC HEALTH IMPACT BP-CHECK will inform which hypertension diagnostic methods are most accurate, acceptable, and feasible to implement in primary care.

Abstract
The aim of this study was to review and describe indications for intraaortic balloon counterpulsation (IABP) use and identify the impact these have on outcomes at an Australian cardiothoracic tertiary referral hospital. A secondary aim was comparison of the Australian practice with a large multinational IABP data registry. Patient demographics, IABP indication, IABP complication rate and mortality in 662 patients treated with IABP at The Prince Charles Hospital (TPCH), Brisbane, between January 1994 and December 2004 inclusive were compared with The Benchmark Counterpulsation Outcomes Registry. Data were collected between 1994 and 2000 by retrospective patient record review and prospectively using the Benchmark database from 2001 to 2004. Statistical analysis was undertaken usingSAS (v8.2) software. The mean age of patients managed with IABP at TPCH (71.6% male) was 63.4 years (SD 12.4). In-hospital mortality rate was 22% and the complication rate was 10.3%. TPCH indications for IABP were: weaning from cardiopulmonary bypass (34.2%); cardiogenic shock (24.4%); preoperative support (13%); catheter laboratory support (10.6%); refractory ventricular failure (7.3%); ischaemia related to intractable ventricular arrhythmias (4.5%); unstable refractory angina (4%); mechanical complications due to acute myocardial infarction (1.2%) and other (0.4%) (0.4% not reported). In comparison to Benchmark, IABP at TPCH demonstrated a prejudice toward intraoperative use (34.2% versus 16.6%; P= <0.0001) and an aversion to catheter laboratory support (10.6% versus 19%; P= <0.0001). TPCH and Benchmark IABP outcomes demonstrated comparable mortality (22% versus 20.8%; P=ns) but increased TPCH complications (10.3% vs. 6.2%; P= <0.0001) owing to a 2% difference in observed insertion site bleeding.

Abstract
BACKGROUND There is in vitro evidence that T cells from allergic patients react to benzylpenicillin-human serum albumin (BP-HSA) bioconjugates. Our group has recently shown the existence of naïve CD4+ T cells recognizing BP-HSA in healthy donors. However, BP-haptenated peptides from HSA participating in the immunization of allergic patients have never been identified. The purpose of the present study is to identify immunodominant BP-haptenated peptides from HSA involved in immunization of patients to BP and to refine the frequency calculation of naïve CD4+ T cells recognizing BP. METHODS Co-cultures were established with CD4+ T cells from non-allergic donors and mature autologous dendritic cells (DCs) loaded with BP-HSA or BP-haptenated peptides from HSA. The CD4+ T-cell response specific for BP-HSA or for individual BP-haptenated peptides was measured using an interferon-γ (IFN-γ) ELISpot assay. The frequency of BP-specific CD4+ T cells was then calculated using the Poisson distribution. BP-HSA and BP-haptenated peptides recognition by allergic patients was evaluated on peripheral blood mononuclear cells (PBMCs) using a lymphocyte transformation test (LTT). RESULTS Results showed that BP-HSA and BP-haptenated peptides were recognized by naïve T cells from 15/16 and 13/14 tested healthy donors, respectively. Most donors responded to 3 peptides with BP covalently bound on lysines 159, 212, and 525. Two of these benzylpenicilloylated peptides (lysines 159 and 525) were also found to induce PBMCs proliferation in patients with allergic reaction to penicillins. CONCLUSION This study identifies and characterizes for the first time the BP-haptenated peptides from HSA involved in the immunization of patients to penicillins.

Abstract
Background
Hyperglycemia leading to increased oxidative stress is implicated in the increased risk for the development of macrovascular and microvascular complications in patients with type 1 diabetes mellitus.
Methods and Results
A random subcohort of 349 participants was selected from the
DCCT
/
EDIC
(Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications) cohort. This included 320 controls and 29 cardiovascular disease cases that were augmented with 98 additional known cases to yield a case cohort of 447 participants (320 controls, 127 cases). Biosamples from
DCCT
baseline, year 1, and closeout of
DCCT
, and 1 to 2 years post‐
DCCT
(
EDIC
years 1 and 2) were measured for markers of oxidative stress, including plasma myeloperoxidase, paraoxonase activity, urinary F
2α
isoprostanes, and its metabolite, 2,3 dinor‐8
iso
prostaglandin F
2α
. Following adjustment for glycated hemoblobin and weighting the observations inversely proportional to the sampling selection probabilities, higher paraoxonase activity, reflective of antioxidant activity, and 2,3 dinor‐8
iso
prostaglandin F
2α
, an oxidative marker, were significantly associated with lower risk of cardiovascular disease (−4.5% risk for 10% higher paraoxonase,
P
<0.003; −5.3% risk for 10% higher 2,3 dinor‐8
iso
prostaglandin F
2α
,
P
=0.0092). In contrast, the oxidative markers myeloperoxidase and F
2α
isoprostanes were not significantly associated with cardiovascular disease after adjustment for glycated hemoblobin. There were no significant differences between
DCCT
intensive and conventional treatment groups in the change in all biomarkers across time segments.
Conclusions
Heightened antioxidant activity (rather than diminished oxidative stress markers) is associated with lower cardiovascular disease risk in type 1 diabetes mellitus, but these biomarkers did not change over time with intensification of glycemic control.

Abstract
Large-scale deforestation, intensive land use and unfavourable rainfall conditions are responsible for significant continuous degradation of the Haitian uplands. To develop soil conservation strategies, simple and cost-effective methods are needed to assess rates of soil loss from farmland in Haiti. The fallout radionuclide caesium-137 (137Cs) provides one such means of documenting medium-term soil redistribution rates. In this contribution, the authors report the first use in Haiti of 137Cs measurements to document soil redistribution rates and the associated pattern of erosion/sedimentation rates along typical hillslopes within a traditional upland Haitian farming area. The local 137Cs reference inventory, measured at an adjacent undisturbed flat area, was 670 Bq m-2 (SD = 100 Bq m-2, CV = 15%, n = 7). Within the study area, where cultivation commenced in 1992 after deforestation, three representative downslope transects were sampled. These were characterized by 137Cs inventories ranging from 190 to 2200 Bq m-2. Although, the study area was cultivated by the local farmers, the 137Cs depth distributions obtained from the area differed markedly from those expected from a cultivated area. They showed little evidence of tillage mixing within the upper part of the soil or, more particularly, of the near-uniform activities normally associated with the plough layer or cultivation horizon. They were very similar to that found at the reference site and were characterized by high 137Cs activities at the surface and much lower activities at greater depths. This situation is thought to reflect the traditional manual tillage practices which cause limited disturbance and mixing of the upper part of the soil. It precluded the use of the conversion models normally used to estimate soil redistribution rates from 137Cs measurements on cultivated soils and the Diffusion and Migration conversion model frequently used for uncultivated soils was modified for application to the cultivated soils of the study area, in order to take account of the unusual local conditions. The model was also modified to take account of the fact that cultivation in the study area commenced in 1992, rather than predating the period of weapons test fallout which extended from the mid 1950s to the 1970s. Erosion rates on the upper parts of the hillside involved in the study were found to be relatively high and ca. -23 t ha-1 y-1 with low spatial variability. In the lower, flatter areas at the bottom of the slope, deposition occurred. Deposition rates were characterized by high spatial variability, ranging from 6.0 to 71 t ha-1 y-1. Soil redistribution rates of this magnitude are a cause for concern and there is an urgent need to implement soil conservation measures to ensure the longer-term sustainability of the local agricultural practices.

Abstract
Importance:
The US Preventive Services Task Force recommends screening adults for high blood pressure (BP). If BP is high, out-of-office BPs are recommended before making a new diagnosis of hypertension, preferably using 24 hour ambulatory BP monitoring (ABPM), because over 30% have normal BPs outside of clinic or “White coat” hypertension with risk of cardiovascular events and death similar to those without hypertension. Currently few physicians use and few patients have heard of ABPM, which may be less convenient than clinic, home, or kiosk-based monitoring.
Objective:
The BP Check randomized controlled diagnostic study will compare the accuracy and acceptability of clinic, home, and kiosk-based BP monitoring compared to ABPM for diagnosing hypertension. The study aims, design, protocols, materials, and evaluation described below are informed by patient, health care, policy, and expert stakeholders.
Methods:
Adults ages 18-85 will be recruited and randomized to routine screening via clinic screening, home BP monitoring over 5 days, or kiosk-based monitoring on 3 separate days. After completion all participants will complete ABPM. Mean BP assessed via each screening method (clinic, home, and kiosk) will be compared with 24 hour APBM to assess the accuracy of each method. We will also assess the acceptability of each method from the patients’ perspective and the impact of the tests longer-term. Finally, a mixed method analysis is planned to explore physician knowledge and beliefs about BP measurement, diagnosing hypertension, and the perceived feasibility of using each of the tested BP strategies in routine clinical practice.
Results:
Enrollment began in May of 2017 with a target of randomizing 510 participants.
Conclusion and Public Health Impact:
BP-CHECK will inform which hypertension diagnostic methods are most accurate, acceptable to patients, and feasible to implement in primary care. This evidence-base is critical to compare alternate methods of diagnosing hypertension to ABPM

Abstract
Cancer patients with bone metastases have previously been excluded from participation in physical activity programmes due to concerns of skeletal fractures. Our aim was to provide initial information on the association between physical activity levels and physical and mental health outcomes in prostate cancer patients with bone metastases. Between 2012 and 2015, 55 prostate cancer patients (mean age 69.7 ± 8.3; BMI 28.6 ± 4.0) with bone metastases (58.2% >2 regions affected) undertook assessments for self-reported physical activity, physical and mental health outcomes (SF-36), objective physical performance measures and body composition by DXA. Sixteen men (29%) met the current aerobic exercise guidelines for cancer survivors, while 39 (71%) reported lower aerobic exercise levels. Men not meeting aerobic exercise guidelines had lower physical functioning (p = .004), role functioning (physical and emotional) (p < .05), general health scores (p = .014) as well all lower measures of physical performance (p < .05). Lower levels of aerobic exercise are associated with reduced physical and mental health outcomes in prostate cancer patients with bone metastases. While previous research has focused primarily in those with non-metastatic disease, our initial results suggest that higher levels of aerobic exercise may preserve physical and mental health outcomes in prostate cancer patients with bone metastases.

Abstract
In 2014 a consensus conference convened by the International Society of Urological Pathology (ISUP) adopted amendments to the criteria for Gleason grading and scoring (GS) for prostatic adenocarcinoma. The meeting defined a modified grading system based on 5 grading categories (grade 1, GS 3+3; grade 2, GS 3+4; grade 3, GS 4+3; grade 4, GS 8; grade 5, GS 9-10). In this study we have evaluated the prognostic significance of ISUP grading in 496 patients enrolled in the TROG 03.04 RADAR Trial. There were 19 grade 1, 118 grade 2, 193 grade 3, 88 grade 4 and 79 grade 5 tumours in the series, with follow-up for a minimum of 6.5 years. On follow-up 76 patients experienced distant progression of disease, 171 prostate specific antigen (PSA) progression and 39 prostate cancer deaths. In contrast to the 2005 modified Gleason system (MGS), the hazards of the distant and PSA progression endpoints, relative to grade 2, were significantly greater for grades 3, 4 and 5 of the 2014 ISUP grading scheme. Comparison of predictive ability utilising Harrell's concordance index, showed 2014 ISUP grading to significantly out-perform 2005 MGS grading for each of the three clinical endpoints.

Abstract
Recent studies have noted an increased risk of low energy subtrochanteric and femoral shaft fractures termed "atypical femur fractures" (AFFs) associated with long-term bisphosphonate use. As such, many clinicians have begun recommending a "drug holiday" to reduce the risks associated with long-term bisphosphonate use. We present two cases of AFFs occurring during a 4-year or greater drug holiday following long-term bisphosphonate use. These findings highlight the need to reevaluate optimal bisphosphonate therapy duration, dosage, as well as initiation and duration of a drug holiday with continued monitoring in the prevention of AFFs.

Abstract
AIMS The effects of radiotherapy on health-related quality of life (HRQOL) may influence decisions about adjuvant radiotherapy after breast-conserving surgery. We sought women's ratings of HRQOL during and after radiotherapy. MATERIALS AND METHODS Women completed HRQOL measures before, during and after adjuvant radiotherapy for node-negative, hormone receptor-positive breast cancers that were less than 2 cm in size. Acute and late toxicities were rated by clinicians. RESULTS There were 161 participants with a median age of 58 years (range 34-82). Mean scores for most aspects of HRQOL worsened only slightly during radiotherapy and improved to baseline levels or better within a few months. The symptoms rated as most distressing were: difficulty sleeping (29%), fatigue (23%), breast discolouration (21%), uncertainty about the future (18%), feeling sad or depressed (18%), feeling anxious or worried (19%). Most rated their experience as better (39%) or much better (28%) than expected. Grade 3 toxicities were rare (5% acute, 1% late) with no grade 4 toxicities. CONCLUSIONS Radiotherapy was associated with transient and generally mild impairments in a few aspects of HRQOL. Concerns about adverse effects on HRQOL should not weigh heavily on decisions about adjuvant breast radiotherapy.

Abstract
AIM Hyperglycaemia is an important risk factor for acute myocardial infarction. It can lead to increased induction of non-oxidative glucose pathways (NOGPs) - polyol and hexosamine biosynthetic pathways, advanced glycation end products and protein kinase C - that may contribute to cardiovascular diseases onset. However, the precise underlying mechanisms remain poorly understood. Here we hypothesized that acute hyperglycaemia increases myocardial oxidative stress and NOGP activation resulting in cardiac dysfunction during ischaemia-reperfusion and that inhibition of, and/or shunting flux away from NOGPs [by benfotiamine (BFT) treatment], leads to cardioprotection. METHODS We employed several experimental systems: (i) Isolated rat hearts were perfused ex vivo with Krebs-Henseleit buffer containing 33 mm glucose vs. controls (11 mm glucose) ± global ischaemia and reperfusion ± BFT (first 20 min of reperfusion); (ii) Infarct size determination as per the ischaemic protocol, but with regional ischaemia and reperfusion ± BFT treatment; in separate experiments, NOGP inhibitors were also employed for (i) and (ii); and (iii) In vivo coronary ligations performed on streptozotocin-treated rats ± BFT treatment (early reperfusion). RESULTS Acute hyperglycaemia generated myocardial oxidative stress, NOGP activation and apoptosis, but caused no impairment of cardiac function during pre-ischaemia, thereby priming hearts for later damage. Following ischaemia-reperfusion (under hyperglycaemic conditions), such effects were exacerbated together with cardiac contractile dysfunction. Moreover, inhibition of respective NOGPs and shunting away by BFT treatment (in part) improved cardiac function during ischaemia-reperfusion. CONCLUSION Coordinate NOGP activation in response to acute hyperglycaemia results in contractile dysfunction during ischaemia-reperfusion, allowing for the development of novel cardioprotective agents.

Abstract
The best technique for anastomosis of the donor ureter remains unresolved and an individual surgeon's preferred technique is likely to be based on training background. This retrospective analysis compares three ureteroneocystostomy techniques in 204 consecutive transplants with an overall ureteric complication rate of 7.3%. Ureteric complications after kidney transplantation present early, are more common when using deceased donor kidneys, and, require complex reconstructive surgery to resolve. Three significant and related findings have been demonstrated with a common theme related to the length of the transplanted ureter, and not, the debate over extravesical versus intravesical techniques.
