Abstract

Abstract Wild bees are declining, mainly due to the expansion of urban habitats that have led to land-use changes. Effects of urbanization on wild bee communities are still unclear, as shown by contrasting reports on their species and functional diversities in urban habitats. To address this current controversy, we built a large dataset, merging 16 surveys carried out in 3 countries of Western Europe during the past decades, and tested whether urbanization influences local wild bee taxonomic and functional community composition. These surveys encompassed a range of urbanization levels, that were quantified using two complementary metrics: the proportion of impervious surfaces and the human population density. Urban expansion, when measured as a proportion of impervious surfaces, but not as human population density, was significantly and negatively correlated with wild bee community species richness. Taxonomic dissimilarity of the bee community was independent of both urbanization metrics. However, occurrence rates of functional traits revealed significant differences between lightly and highly urbanized communities, for both urbanization metrics. With higher human population density, probabilities of occurrence of above-ground nesters, generalist and small species increased. With higher soil sealing, probabilities of occurrence of above-ground nesters, generalists and social bees increased as well. Overall, these results, based on a large European dataset, suggest that urbanization can have negative impacts on wild bee diversity. They further identify some traits favored in urban environments, showing that several wild bee species can thrive in cities.

Abstract

Abstract Climate change has a diverse range of impacts on wild bees, including their phenology or timing of life history events. Climate‐driven phenological shifts can not only impact individuals at species level but also threaten the vital pollination service that wild bees provide to both wild plants and cultivated crops. Despite their involvement in pollination, for most bee species, especially in Great Britain, little is known about phenological shifts. This study makes use of 40 years of presence‐only data for 88 species of wild bees to analyse shifts in emergence dates, both over time and in relation to temperature. The analyses reveal widespread advances in emergence dates of British wild bees, at an average rate of 0.40 ± 0.02 days per year since 1980 across all species in the study data set. Temperature is a key driver of this shift, with an average advance of 6.5 ± 0.2 days per 1°C warming. For change in emergence dates both over time and in relation to temperature, there was significant species‐specific variation, with 14 species showing significant advances over time and 67 showing significant advances in relation to temperature. Traits did not appear to explain variation in individual species' responses, with overwintering stage, lecty, emergence period and voltinism considered as possible explanatory traits. Pairwise comparisons showed no differences in sensitivity of emergence dates to increasing temperature between trait groups (groups of species which share all four traits) that differed by only one trait. These results highlight not only a direct impact of temperature on the phenology of wild bees themselves but also the species‐specific shifts highlight a possible impact on the temporal structure of bee communities and the pollination networks for which the wild bees are so crucial.

Abstract

Climate, landscape composition, management practice, and wild bee pollination are all variables thought to play significant roles in commercial apple production. However, how these variables affect production efficiency under field-realistic conditions has not been investigated at large geographical scales. We combined intensive standardized field surveys (using netting and pan traps) with structural equation models to explore the relative impact of biotic and abiotic variables on bee diversity, apple yield and fruit quality, and their ability to represent reliable proxies of apple production. Here we show that apple yields are mainly driven by management practice, without evidence for a significantly superior contribution by managed honey bees. Total wild bee diversity, while negatively correlated with honey bee dominance, promoted apple quality by enhancing seed set number. Our study demonstrates that even across a broad geographical range there is potential to harness wild bee diversity as nature-based solution and as a substitute to an exclusive reliance on honey bees in the context of commercial apple production.

Abstract

Abstract Widespread concern over declines in pollinating insects has led to numerous recommendations of which “pollinator-friendly” plants to grow and help turn urban environments into valuable habitat for such important wildlife. Whilst communicated widely by organisations and readily taken up by gardeners, the provenance, accuracy, specificity and timeliness of such recommendations remain unclear. Here we use data (6429 records) gathered through a UK-wide citizen science programme (BeeWatch) to determine food plant use by the nations’ bumblebee species, and show that much of the plant use recorded does not reflect practitioner recommendations: correlation between the practitioners’ bumblebee-friendly plant list (376 plants compiled from 14 different sources) and BeeWatch records (334 plants) was low (r = 0.57), and only marginally higher than the correlation between BeeWatch records and the practitioners’ pollinator-friendly plant list (465 plants from 9 different sources; r = 0.52). We found pollinator-friendly plant lists to lack independence (correlation between practitioners’ bumblebee-friendly and pollinator-friendly lists: r = 0.75), appropriateness and precision, thus failing to recognise the non-binary nature of food-plant preference (bumblebees used many plants, but only in small quantities, e.g. lavender—the most popular plant in the BeeWatch database—constituted, at most, only 11% of records for any one bumblebee species) and stark differences therein among species and pollinator groups. We call for the provision and use of up-to-date dynamic planting recommendations driven by live (citizen science) data, with the possibility to specify pollinator species or group, to powerfully support transformative personal learning journeys and pollinator-friendly management of garden spaces.

Abstract

Insect pollinators are a key component of biodiversity; they also play a major role in the reproduction of many species of wild plants and crops. It is widely acknowledged that insect pollinators are threatened by many environmental pressures, mostly of anthropogenic nature. Their decline is a global phenomenon. A better understanding of their distribution can help their monitoring and ultimately facilitate conservation actions. Since we only have partial knowledge of where pollinator species occur, the possibility to predict suitable environmental conditions from scattered species records can facilitate not only species monitoring, but also the identification of areas potentially vulnerable to pollinators decline. This data paper contains the predicted distribution of 47 species of bumblebees across the 28 Member States of the European Union (EU-28). Amongst the wild pollinators, bumblebees are one of the major groups contributing to the production of many crop species, hence their decline in Europe, North America and Asia can potentially threaten food security. Predictions were derived from distribution models, using species records with a spatial resolution of 10 km accessed from a central repository. Predictions were based on records from 1991 to 2012 and on a series of spatial environmental predictors from three main thematic areas: land use and land cover, climate and topography. These distributions were used to estimate the value of pollination as an ecosystem service. In light of the recent European Pollinators Initiative, this paper provides valuable information for a better understanding of where wild pollinators occur and it should be extended to other pollinator species.

Abstract

Abstract Background High quality, contemporary data regarding patterns of chronic disease is essential for planning by health services, policy makers and local governments, but surprisingly scarce, including in rural Australia. This dearth of data occurs despite the recognition that rural Australians live with high rates of ill health, poor health behaviours and restricted access to health services. Crossroads-II is set in the Goulburn Valley, a rural region of Victoria, Australia 100–300 km north of metropolitan Melbourne. It is primarily an irrigated agricultural area. The aim of the study is to identify changes in the prevalence of key chronic health conditions including the extent of undiagnosed and undermanaged disease, and association with access to care, over a 15 year period. Methods/design This study is a 15 year follow up from the 2000–2003 Crossroads-I study (2376 households participated). Crossroads-II includes a similar face to face household survey of 3600 randomly selected households across four towns of sizes 6300 to 49,800 (50% sampled in the larger town with the remainder sampled equally from the three smaller towns). Self-reported health, health behaviour and health service usage information is verified and supplemented in a nested sub-study of 900 randomly selected adult participants in ‘clinics’ involving a range of additional questionnaires and biophysical measurements. The study is expected to run from October 2016 to December 2018. Discussion Besides providing epidemiological and health service utilisation information relating to different diseases and their risk factors in towns of different sizes, the results will be used to develop a composite measure of health service access. The importance of access to health services will be investigated by assessing the correlation of this measure with rates of undiagnosed and undermanaged disease at the mesh block level. Results will be shared with partner organisations to inform service planning and interventions to improve health outcomes for local people.

Abstract

Summary Factors associated with agricultural intensification, for example, loss of seminatural vegetation and pesticide use has been shown to adversely affect the bee community. These factors may impact the bee community differently at different landscape scales. The scale dependency is expected to be more pronounced in heterogeneous landscapes. However, the scale‐dependent response of the bee community to drivers of its decline is relatively understudied, especially in the tropics where the agricultural landscape is often heterogeneous. This study looked at effects of agricultural intensification on bee diversity at patch and landscape scales in a tropical agricultural landscape. Wild bees were sampled using 12 permanent pan trap stations. Patch and landscape characteristics were measured within a 100 m (patch scale) and a 500 m (landscape scale) radius of pan trap stations. Information on pesticide input was obtained from farmer surveys. Data on vegetation cover, productivity, and percentage of agricultural and fallow land (FL) were collected using satellite imagery. Intensive areas in a bee‐site network were less specialized in terms of resources to attract rare bee species while the less intensive areas, which supported more rare species, were more vulnerable to disturbance. A combination of patch quality and diversity as well as pesticide use regulates species diversity at the landscape scale (500 m), whereas pesticide quantity drove diversity at the patch scale (100 m). At the landscape scale, specialization of each site in terms of resources for bees increased with increasing patch diversity and FL while at the patch scale specialization declined with increased pesticide use. Bee functional groups responded differentially to landscape characteristics as well as pesticide use. Wood nesting bees were negatively affected by the number of pesticides used but other bee functional groups were not sensitive to pesticides. Synthesis and Applications: Different factors affect wild bee diversity at the scale of landscape and patch in heterogeneous tropical agricultural systems. The differential response of bee functional groups to agricultural intensification underpins the need for guild‐specific management strategies for wild bee conservation. Less intensively farmed areas support more rare species and are vulnerable to disturbance; consequently, these areas should be prioritized for conservation to maintain heterogeneity in the landscape. It is important to conserve and restore seminatural habitats to maintain complexity in the landscapes through participatory processes and to regulate synthetic chemical pesticides in farm operations to conserve the species and functional diversity of wild bees.

Abstract

Background and study aims The evidence for efficacy and safety of cold snare polypectomy is limited. The aim of this study was to assess the completeness of resection and safety of cold snare polypectomy, using either traditional or dedicated cold snares. Patients and methods This was a prospective, non-randomized study performed at a single tertiary hospital. Adult patients with at least one colorectal polyp (size ≤ 10 mm) removed by cold snare were included. In the first phase, all patients had polyps removed by traditional snare without diathermy. In the second phase, all patients had polyps removed by dedicated cold snare. Complete endoscopic resection was determined from histological examination of quadrantic polypectomy margin biopsies. Immediate or delayed bleeding within 2 weeks was recorded. Results In total, 181 patients with 299 eligible polyps (n = 93 (173 polyps) traditional snare group, n = 88 (126 polyps) dedicated cold snare group) were included. Patient demographics and procedure indications were similar between groups. Mean polyp size was 6 mm in both groups (P = 0.25). Complete polyp resection was 165 /173 (95.4 %; 95 %CI 90.5 – 97.6 %) in the traditional snare group and 124/126 (98.4 %; 95 %CI 93.7 – 99.6 %) in the dedicated cold snare group (P = 0.16). Serrated polyps, compared with adenomatous polyps, had a higher rate of incomplete resection (7 % vs. 2 %, P = 0.03). There was no statistically significant difference in the rate of immediate bleeding (3 % vs. 1 %, P = 0.41) and there were no delayed hemorrhages or perforations. Conclusions Cold snare polypectomy is effective and safe for the complete endoscopic resection of small (≤ 10 mm) colorectal polyps with either traditional or dedicated cold snares.

Abstract

We have previously reported a world-first phase I clinical trial to treat HCV patients using monocyte-derived dendritic cells (Mo-DC) loaded with HCV-specific lipopeptides. While the brief treatment proved to be safe, it failed to reduce the viral load and induced only transient cell-mediated immune responses, measured by IFNγ ELIspot. Here we reanalysed the PBMC samples from this trial to further elucidate the immunological events associated with the Mo-DC therapy. We found that HCV-specific single- and multi-cytokine secreting T cells were induced by the Mo-DC immunotherapy in some patients, although at irregular intervals and not consistently directed to the same HCV antigen. Despite the vaccination, the responses were generally poor in quality and comprised of primarily single-cytokine secreting cells. The frequency of FOXP3(+) regulatory T cells (Treg) fluctuated following DC infusion and eventually dropped to below baseline by week 12, an interesting trend suggesting that the vaccination may have resulted in a more subtle outcome than was initially apparent. Our data suggested that Mo-DC therapy induced complex immune responses in vivo that may or may not lead to clinical benefit.

Abstract

We reported previously that a proportion of natural CD25(+) cells isolated from the PBMC of HCV patients can further upregulate CD25 expression in response to HCV peptide stimulation in vitro, and proposed that virus-specific regulatory T cells (Treg) were primed and expanded during the disease. Here we describe epigenetic analysis of the FOXP3 locus in HCV-responsive natural CD25(+) cells and show that these cells are not activated conventional T cells expressing FOXP3, but hard-wired Treg with a stable FOXP3 phenotype and function. Of approximately 46,000 genes analyzed in genome wide transcription profiling, about 1% were differentially expressed between HCV-responsive Treg, HCV-non-responsive natural CD25(+) cells and conventional T cells. Expression profiles, including cell death, activation, proliferation and transcriptional regulation, suggest a survival advantage of HCV-responsive Treg over the other cell populations. Since no Treg-specific activation marker is known, we tested 97 NS3-derived peptides for their ability to elicit CD25 response (assuming it is a surrogate marker), accompanied by high resolution HLA typing of the patients. Some reactive peptides overlapped with previously described effector T cell epitopes. Our data offers new insights into HCV immune evasion and tolerance, and highlights the non-self specific nature of Treg during infection.

Abstract

Progressive liver fibrosis related to non-alcoholic fatty liver disease (NAFLD) is associated with all-cause and liver-related mortality. We assessed vibration-controlled transient elastography (VCTE) as a predictor of mortality.Data from patients who underwent VCTE for NAFLD at four large health services in Victoria, Australia between the years 2008 and 2019 were linked to state-wide data registries. Cause of death (COD) and predictors of all-cause mortality were subsequently analysed using descriptive statistics and Cox-proportional regression analysis.Of 7079 VCTE records submitted for data linkage, 6341 were matched via data registry linkage. There were 217 deaths over a 22 653 person-year follow-up. COD included malignancies other than hepatocellular carcinoma (HCC) (18.0%, n = 39), sepsis (16.1%, n = 35), decompensated liver disease (15.2%, n = 33), cardiac disease (15.2%, n = 33) and HCC 6.0% (n = 13). Controlled attenuation parameter (CAP) was not associated with mortality in univariable analysis (HR = 1.00, CI 1.0-1.0, p = .488). Increased liver stiffness measurement (LSM) (HR 1.02 per kiloPascal, CI 1.01-1.03, p .001), Charlson comorbidity index (CCI) (HR 1.32 for each point, CI 1.27-1.38, p .001) and age (HR 1.05 per annum, CI 1.03-1.07, p .001) were each associated with higher rates of all-cause mortality in multivariable analysis. LSM ≥10 kPa suggestive of compensated advanced chronic liver disease (cACLD) was associated with mortality in multivariable analysis (HR 2.31, CI 1.73-3.09, p .001).VCTE LSM, in addition to age and CCI, is independently associated with increased all-cause mortality in a large cohort with NAFLD.

Abstract

Introduction: Hepatocellular carcinoma (HCC) is a serious complication of chronic liver disease. Lenvatinib is an oral multikinase inhibitor registered to treat advanced HCC. This study evaluates the real-world experience with lenvatinib in Australia.Methods:We conducted a retrospective cohort study of patients treated with lenvatinib for advanced HCC between July 2018 and November 2020 at eleven Australian tertiary centres. Baseline demographic data, tumour characteristics, lenvatinib dosing, adverse events (AEs) and clinical outcomes were collected. Overall survival (OS) was the primary outcome. Progression free survival (PFS) and AEs were secondary outcomes.Results: A total of 155 patients were included and were predominantly male (90.7%) with a median age of 65 years (interquartile range [IQR]: 59-75). The main causes of chronic liver disease were hepatitis C infection (40.0%) and alcohol-related liver disease (34.2). Median OS and PFS were 7.7 (95% confidence interval [CI]: 5.8-14.0) and 5.3 months (95% CI: 2.8- 9.2) respectively. Multivariate predictors of mortality were the need for dose reduction due to AEs (Hazard ratio [HR] 0.41, pConclusions:Lenvatinib remains safe and effective in real-world use. Treatment emergent diarrhoea and hypertension, and the need for dose reduction appear to predict better OS.

Abstract

Background The prevalence of primary biliary cholangitis (PBC) reported in different countries varies significantly and in some parts of the world appears to be increasing. The aim of this study was to determine the 2013 prevalence of PBC in Victoria, Australia, and to determine the time trend by comparing it with previous studies undertaken in 1991 and 2002. Methods Four case-finding methods were used to identify cases of PBC in Victoria: (1) physicians’ survey; (2) tertiary hospital search; (3) liver transplant database search; and (4) private pathology antimitochondrial antibody search. Results The prevalence of PBC in Victoria, Australia, is 189.0 per million using all four methods. The average annual increase in prevalence from 1991 to 2013 was 7.7 per million per year. Using the same case-finding methods as the 1991 Victorian prevalence study (methods 1 and 2), the prevalence of PBC increased from 19.1 per million in 1991 to 49.4 per million in 2002 (P Conclusions The current prevalence of PBC in Victoria is significantly higher than previously reported. The use of private pathology-based case-finding methods is important in identifying the maximum number of PBC cases. Key messages PBC prevalence in Victoria increased significantly since previous surveys, to 189 per million persons. Including pathology-based case ascertainment yields improved identification of cases.

Abstract

The present work systematically investigates the effects of BN nanopowder functionalization on the processability, microstructure and tensile response of the custom Powder Bed Fusion Laser Beam (PBF-LB) Al alloy ‘AMALLOY3D’. The results show that a minor addition of BN (0.3 % by weight) not only produces near fully dense parts (99.91 %), but is also paired with improved flowability, enhancing the overall processability. Electron backscatter diffraction (EBSD) analysis revealed the transformation to a fully equiaxed grain structure in the BN-functionalized material, resulting in a 40 % increase in yield strength. Energy dispersive spectroscopy using a scanning transmission electron microscope (STEM-EDS) was employed to reveal the intricate secondary phases’ arrangements. These observations coupled with the help of the CALPHAD approach led to the reconstruction of the solidification history of AMALLOY3D and the BN-functionalized material. The present study unravels the complex dynamics leading to the columnar-to-equiaxed transition in BN-reinforced AMCs, proving that such unique microstructures and exceptional tensile properties can be achieved without compromising PBF-LB processability.

Abstract

Identifying private gardens in the U.K. as key sites of environmental engagement, we look at how a longer-term online citizen science programme facilitated the development of new and personal attachments of nature. These were visible through new or renewed interest in wildlife-friendly gardening practices and attitudinal shifts in a large proportion of its participants. Qualitative and quantitative data, collected via interviews, focus groups, surveys and logging of user behaviours, revealed that cultivating a fascination with species identification was key to both ‘helping nature’ and wider learning, with the programme creating a space where scientific and non-scientific knowledge could co-exist and reinforce one another.

Abstract

© 2019 Elsevier Ltd. All rights reserved., Background: Non-alcoholic steatohepatitis (NASH) is a common type of chronic liver disease that can lead to cirrhosis. Obeticholic acid, a farnesoid X receptor agonist, has been shown to improve the histological features of NASH. Here we report results from a planned interim analysis of an ongoing, phase 3 study of obeticholic acid for NASH. Methods: In this multicentre, randomised, double-blind, placebo-controlled study, adult patients with definite NASH, non-alcoholic fatty liver disease (NAFLD) activity score of at least 4, and fibrosis stages F2-F3, or F1 with at least one accompanying comorbidity, were randomly assigned using an interactive web response system in a 1:1:1 ratio to receive oral placebo, obeticholic acid 10 mg, or obeticholic acid 25 mg daily. Patients were excluded if cirrhosis, other chronic liver disease, elevated alcohol consumption, or confounding conditions were present. The primary endpoints for the month-18 interim analysis were fibrosis improvement (≥1 stage) with no worsening of NASH, or NASH resolution with no worsening of fibrosis, with the study considered successful if either primary endpoint was met. Primary analyses were done by intention to treat, in patients with fibrosis stage F2-F3 who received at least one dose of treatment and reached, or would have reached, the month 18 visit by the prespecified interim analysis cutoff date. The study also evaluated other histological and biochemical markers of NASH and fibrosis, and safety. This study is ongoing, and registered with ClinicalTrials.gov, NCT02548351, and EudraCT, 20150-025601-6. Findings: Between Dec 9, 2015, and Oct 26, 2018, 1968 patients with stage F1-F3 fibrosis were enrolled and received at least one dose of study treatment; 931 patients with stage F2-F3 fibrosis were included in the primary analysis (311 in the placebo group, 312 in the obeticholic acid 10 mg group, and 308 in the obeticholic acid 25 mg group). The fibrosis improvement endpoint was achieved by 37 (12%) patients in the placebo group, 55 (18%) in the obeticholic acid 10 mg group (p=0·045), and 71 (23%) in the obeticholic acid 25 mg group (p=0·0002). The NASH resolution endpoint was not met (25 [8%] patients in the placebo group, 35 [11%] in the obeticholic acid 10 mg group [p=0·18], and 36 [12%] in the obeticholic acid 25 mg group [p=0·13]). In the safety population (1968 patients with fibrosis stages F1-F3), the most common adverse event was pruritus (123 [19%] in the placebo group, 183 [28%] in the obeticholic acid 10 mg group, and 336 [51%] in the obeticholic acid 25 mg group); incidence was generally mild to moderate in severity. The overall safety profile was similar to that in previous studies, and incidence of serious adverse events was similar across treatment groups (75 [11%] patients in the placebo group, 72 [11%] in the obeticholic acid 10 mg group, and 93 [14%] in the obeticholic acid 25 mg group). Interpretation: Obeticholic acid 25 mg significantly improved fibrosis and key components of NASH disease activity among patients with NASH. The results from this planned interim analysis show clinically significant histological improvement that is reasonably likely to predict clinical benefit. This study is ongoing to assess clinical outcomes.

31. Siegfried Sassoon

Author

John Stuart Roberts and John Stuart Roberts

Abstract

'A FINE ENGROSSING, SYMPATHETIC STUDY OF SASSOON'- THE TIMESWith two collections of his verse written during the First World War, Siegfried Sassoon established himself as among the greatest of the war poets. Beyond that, the accounts he left of his service with the Royal Welch Fusiliers on the Western Front, beginning with Memoirs of a Fox-Hunting Man in 1928, rank perhaps as highly as his poetry, and have done much to shape our modern perception of that war. His is, and remains, one of the most significant voices of his generation - and arguably the most eloquent.As an infantry officer, Sassoon's courage won him the Military Cross (and a recommendation for the VC) for rescuing men under fire, while his boldness in action earned him the nickname'Mad Jack'; he was also wounded several times, once seriously. As the war dragged on, however, he came to see it as a cynical exercise, leading him to write an anti-war letter to The Times, and to tear the ribbon of his MC from his tunic and throw it into the River Mersey. Alarmed, the authorities sent him to a hospital for shell-shocked officers in Scotland, where he came under the care of the leading psychoanalyst Dr W. H. R. Rivers, and met and befriended a young officer of the Manchester Regiment named Wilfred Owen. Although Sassoon returned to active service, his hatred for the war remained, and by the time of the Armistice in 1918 he had declared himself a pacifist.John Stuart Roberts's widely praised biography is a gripping account of a complex man who was at once a product of the establishment and one of its most passionate critics; a war hero and a pacifist who, although a towering literary figure, refused to align himself with any particular movement.Written with a clarity and directness that would have pleased the poet himself, this is a biography that looks beyond the common perception of Sassoon as only a war poet to reveal the man in full. It is a book that any admirer of Siegfried Sassoon, or anyone who wishes to know more about this enigmatic yet brilliant figure, will cherish.'A MAGNIFICENT BOOK… IT'S FIRST RATE IN EVERY DIRECTION AND I CAN'T IMAGINE A BETTER BIOGRAPHY'- RUPERT HART-DAVIS'FULLY RESEARCHED, INTELLIGENT, DETAILED AND READABLE...LOOKS SEARCHINGLY AT ALL ASPECTS OF THIS HIGHLY COMPLEX, MULTI-TALENTED AND DEEPLY MIXED-UP MAN'- LITERARY REVIEW'AN IMMENSELY READABLE BIOGRAPHY WHICH IS MADE EVEN MORE MOVING BY HAVING A TRULY TRAGIC SUBJECT'- TIMES LITERARY SUPPLEMENT'ONE OF OUR GREATEST WAR POETS… STUART ROBERTS GIVES A THOUGHTFUL, CONVINCING ACCOUNT'- SUNDAY TIMES'A BENCHMARK BIOGRAPHY - SPLENDID AND SENSITIVE'- COUNTRY LIFE'A MASTERLY ACCOUNT OF SIEGFRIED SASSOON'S LIFE'- THE TABLET

Abstract

Siegfried Sassoon is mostly remembered for the devastating poetry he wrote during World War One as a result of leading his troops'over the top'to certain death. This episode in his life--when he was sent to military hospital suffering from shell-shock and his heroic return to the Front--is covered extensively in his own writing, and has overshadowed his later literary output. But his more mature poetry is resuscitated in this sensitive, exhaustively researched biography. As well as recounting the friendships'Siggy'famously had with fellow poets Robert Graves and Wilfred Owen, Roberts delves into the more private arena of Sassoon's covert homosexuality and his ill-fated marriage. We learn about Sassoon the passionate golfer and bloodthirsty fox-hunter, all of which adds greater depth to this complex man. Roberts also digs deep into his subject's psyche to reveal a fixation with father figures which started during the War when he was under analysis (and arose from the early death of his father); and uncovers new sources of information concerning Sassoon's conversion to Catholicism. This fresh material means that the earlier life is somewhat neglected, but, then, as Sassoon himself said'My real biography is my poetry.'

Abstract

Background and Purpose : Developing improved methods for analysis of the modified Rankin Scale (mRS) remains a critical issue for the stroke research community. A recently proposed permutation-based approach is assumption-free and easily interpretable but computationally intensive and does not provide confidence intervals to quantify the precision of the effect size estimate. We aimed to develop a method to overcome these limitations. Methods : We propose a procedure using generalized odds ratios to estimate the odds that a patient who received the investigational treatment will have a better outcome than a patient receiving standard treatment. This approach was validated against the permutation method using hypothetical clinical trial scenarios of neuroprotective effect, early recanalization effect, late recanalization effect, and random benefit. Results : The generalized odds ratio approach had strong agreement with the permutation approach provided sample size was >15 patients per treatment arm. Simulation established that the confidence intervals generated were accurate. Ignoring patient pairs with tied mRS scores overestimates the treatment effect compared with splitting tied mRS scores. Conclusions : In addition to all the advantages of the recently proposed permutation-based approach, our method generates confidence intervals without the need for intensive computational power. The resulting generalized odds ratios are particularly suitable for inclusion in meta-analyses and have a simple and intuitive connection with the number-needed-to-treat measure.

Abstract

The use of non-invasive tests to stage the severity of liver disease (ie. scarring) is now well established in the management of patients with chronic liver disease. This is because assessment of liver scarring provides prognostic information and assists in establishing treatment priorities. One such technique, transient elastography (TE), is a simple, safe and efficient way to estimate liver scarring. FibroScan® (EchoSens, Paris) is the most popular non-invasive device used to assess liver 'hardness' (or stiffness) via TE in Australia. When performed in the appropriate clinical setting, TE provides a reliable method of detecting cirrhosis and excluding significant fibrosis, particularly when the results are supported by clinical and laboratory data.

Abstract

Treatment of gastric variceal rupture remains difficult with current options including transjugular intrahepatic portosystemic shunt and endoscopic therapies having significant side effects or reduced efficacy. We report five cases of gastric varices that were successfully treated with balloon-occluded retrograde transvenous obliteration of varices (BRTO) using Polidocanol foam as an alternative sclerosant to ethanolamine oleate.Patients were recruited with cirrhotic liver disease, a history of upper gastrointestinal bleeding, and large gastric fundal varices confirmed on gastroscopy and CT venogram. BRTO was performed as a same-day procedure using a balloon catheter inserted via a gastro-renal shunt with Polidocanol foam injected and a balloon inflated for 2 h. Follow-up was with repeat CT portovenogram, gastroscopy at 6 weeks post-procedure, and in a gastroenterology liver clinic at 1- to 3-month intervals.Between January and December 2009, five patients safely underwent BRTO therapy of gastric varices without complication. At 6 weeks following the procedure, upper gastrointestinal endoscopy showed complete resolution of varices in 5 out of 5 patients, while CT portovenography showed resolution of varices in 4 out of 5 patients, with results in the last patient inconclusive. Clinical follow-up at 1, 3 and 6 months indicated no further episodes of bleeding.Our study further supports the use of foam sclerosants including Polidocanol in BRTO, showing it is a safe and effective minimally-invasive procedure to treat gastric fundal varices in the short term.

Abstract

Self-lubricating aluminium-based composites reinforced with solid lubricants promise to meet the demand for lightweight materials in green tribological applications. The design advantages granted by additive manufacturing (AM) processes coupled with their capacity for in-situ production of composite materials are yet to be exploited in the realm of Al-transition metal dichalcogenides composites. In this work, laser powder bed fusion (LPBF) was deployed for the in-situ fabrication of Al-WS2 composites for the first time, elucidating the process-structure–property relationships in comparison to reference spark plasma sintering (SPS) samples. The WS2 response to the respective fabrication technique was also firstly investigated through a holistic characterisation. The formation of new phases (W for LPBF, Al5W and Al12W for SPS) provided the potential for microstructural tailoring for optimal tribological performance. For tribological properties, LPBF Al-WS2 exhibited a coefficient of friction (COF) 0.55 ± 0.01 and specific wear rate 3.4 ± 0.3 × 10−3 mm3/N∙m, slightly better than the SPS counterpart (COF 0.57 ± 0.02, specific wear rate 3.6 ± 0.3 × 10−3 mm3/N∙m). Furthermore, a novel methodology for studying the evolution of worn surfaces is proposed and validated, by which a tribo-layer formed at lower friction cycles was observed for the LPBF samples, meaning that AM will also be advantageous for the performance aspect of self-lubricating materials.

Abstract

As the merits of screening at-risk populations for hepatocellular carcinoma (HCC) remain unclear, we compared the clinico-pathologic features and survival of patients with cirrhosis and HCC detected by screening (Group A) to that in non-screened cases (Group B).We studied cirrhotics who developed HCC between 1994 and 2002. During this period, cirrhotics managed by the Gastroenterology Unit were regularly screened at 6-12 monthly intervals while those managed by other hospital units were not. Demographic data, tumor details, treatment received and survival were recorded and compared according to screening status.There were 96 cases identified; 41 by screening (group A) and 55 by non-screening methods (Group B). HCC in Group A were smaller (P0.01), more likely unilobar (P0.01), at an early stage (P0.0005) and before vascular invasion (P0.005) than Group B cases. The frequency of hepatic surgery and/or local ablation was higher in Group A than Group B (P = 0.001). Overall median survival of Group A was 882 days versus 99 days in Group B (P0.0001). One- and 3-year probabilities of survival in Group A were 89% and 38%, versus 33% and 19% in Group B (P0.001). Independent predictors of survival included screening, Child-Pugh score, creatinine, tumor stage and absence of alcohol as the etiology.Screening for HCC in cirrhosis identifies tumors at an earlier stage, results in a higher chance of receiving curative treatment and possibly improves patient survival. The absence of alcoholic liver disease impacts favorably on survival.

Abstract

We have used fragments of the TSH receptor (TSHR) expressed in E. coli as glutathione S-transferase fusion proteins to produce rabbit polyclonal antibodies and a panel (n=5) of monoclonal antibodies to the extracellular fragment of the TSHR. The binding characteristics of the antibodies to linear, conformational, glycosylated and unglycosylated forms of the receptor in different assay systems have been investigated. The reactivity of these antibodies with the TSHR was assessed by Western blotting with both native and recombinant human TSHR expressed in CHO cells, immunoprecipitation of 35S-labelled full-length TSHR produced in an in vitro transcription/ translation system, immunoprecipitation of 125I-TSH/TSHR complexes, inhibition of 125I-TSH binding to the TSHR and fluorescence activated cell sorter (FACS) analysis of binding to CHO-K1 cells expressing the TSHR on their cell surface. Fab fragments of monoclonal antibodies were isolated, labelled with 125I and used to determine the affinity constants of these antibodies with receptor, bound and free Fab being separated by polyethylene glycol (PEG) precipitation. Rabbit polyclonal and mouse monoclonal antibodies reacted with the TSHR in Western blotting and one monoclonal antibody (3C7) was able to inhibit 125I-TSH binding to native human TSHR (74% inhibition), recombinant human TSHR (84% inhibition) and porcine TSHR (65% inhibition). Affinity constant values for TSHR monoclonal antibody Fab fragments calculated using Scatchard analysis were about 10(7) M(-1). Four out of five monoclonal antibodies reacted in FACS analysis with TSHR expressed on the surface of CHO-K1 cells. The FACS unreactive monoclonal (3C7) bound well to detergent solubilised TSH receptors and this emphasised the importance of using a combination of FACS analysis and radioactively-labelled probes in analysis of the TSH receptor. The monoclonal antibodies produced in this study were found to be of relatively low affinity but proved useful for detection of the receptor by Western blotting and by FACS analysis.

Poets, English--20th century--Biography
Abstract

Although it is said that he owed his poetic vision to his Sephardic Jewish roots, Siegfried Sassoon was, in many ways, a conventionally Edwardian squire. And although near-suicidal bravery won him the Military Cross (Sassoon was famously fictionalized in Pat Barker's Regeneration trilogy), his poetry shattered the ideals of wartime heroism. A gifted poet who refused to become part of any literary movement, his friendships ranged from Thomas Hardy and Robert Graves to the Sitwells, Rupert Brooke, and T.E. Lawrence. In this acclaimed biography, John Stuart Roberts skillfully chronicles Sassoon's life and work, including his homosexuality, his marriage, and his quest for a personal religious faith. His inner journey to Catholicism in his final years is charted with a sensitivity and authority that are the hallmarks of this masterly portrait.

Abstract

Seven per cent of 767 patients with cancer studied more than five and as many as ten years ago in our laboratory had positive blood samples. A similar frequency of positive blood samples was obtained when only those patients considered “curable” were tabulated, or those patients studied before, during, and after operation. The survival rate in the entire group of 767 patients was not different with regard to positive or negative blood samples, being 13 and 12 per cent, respectively. The survival rate for “curable” patients with positive blood samples was no different from the survival rate for those with negative blood samples; it was 32 per cent for each category. Although there is no apparent difference in the five to ten year survival rates of all 767 cancer patients, regardless of whether the blood samples are positive or negative, a definite trend is apparent in the decreased survival of patients with a shower of circulating cancer cells during or after operation. Only two of twenty-three patients (8 per cent) with showers of cancer cells demonstrated during operation were alive and well five to ten years postoperatively as compared with a 16 per cent survival (26 of 182) of patients with negative blood samples at all times before, during, and after operation. Also, vascular metastases developed in 39 per cent of those patients with showers of circulating cancer cells during operation as compared with only 18 per cent of those patients with all negative blood samples.
