Abstract
Endovascular repair has revolutionised the emergency treatment of thoracic aortic disease. We report our 10 year experience using this treatment in emergency cases. A prospectively maintained vascular database was analysed. Patients' medical records and CT images stored on the hospital PACS system were also reviewed. Statistical analysis was done using IBM SPSS V21. There were a total of 59 thoracic aortic stenting procedures of which 33 (60% males with a mean age of 58 yrs) were performed for emergency thoracic pathologies: traumatic transection (n = 10), ruptured aneurysm (n = 6), non-traumatic dissection (n = 8) and penetrating aortic ulcer (n = 9). All patients had self-expanding endografts implanted. Two patients required debranching procedures before the endovascular treatment. Thirty-day mortality was 12.1% (4/33). 70% of patients received a single device. There were 7 procedure related complications, 6 requiring re-intervention: thoracotomy and drainage in 2 patients, proximal graft extension in 2, open drainage of groin haematoma in 1 and open repair of a common femoral artery pseudo-aneurysm in one patient. In total 23 patients were transferred from 11 centres nationwide. There were no mortalities or other complications related to patient transfer from peripheral centres. Although acute thoracic aortic pathology is life threatening, appropriate blood pressure management and treatment of associated injuries can result in favourable outcomes. Endovascular repair is a safe and effective treatment option which enables patients to be treated with reduced morbidity and mortality. Transfer of patients with acute pathology to a tertiary centre can safely be performed.

Abstract
Background Bifidobacterial genome analysis has provided insights as to how these gut commensals adapt to and persist in the human GIT, while also revealing genetic diversity among members of a given bifidobacterial (sub)species. Bifidobacteria are notoriously recalcitrant to genetic modification, which prevents exploration of their genomic functions, including those that convey (human) health benefits. Methods PacBio SMRT sequencing was used to determine the whole genome seqeunces of two B. longum subsp. longum strains. The B. longum pan-genome was computed using PGAP v1.2 and the core B. longum phylogenetic tree was constructed using a maximum-likelihood based approach in PhyML v3.0. M.blmNCII was cloned in E. coli and an internal fragment if arfBarfB was cloned into pORI19 for insertion mutagenesis. Results In this study we present the complete genome sequences of two Bifidobacterium longum subsp. longum strains. Comparative analysis with thirty one publicly available B. longum genomes allowed the definition of the B. longum core and dispensable genomes. This analysis also highlighted differences in particular metabolic abilities between members of the B. longum subspecies infantis, longum and suis. Furthermore, phylogenetic analysis of the B. longum core genome indicated the existence of a novel subspecies. Methylome data, coupled to the analysis of restriction-modification systems, allowed us to substantially increase the genetic accessibility of B. longum subsp. longum NCIMB 8809 to a level that was shown to permit site-directed mutagenesis. Conclusions Comparative genomic analysis of thirty three B. longum representatives revealed a closed pan-genome for this bifidobacterial species. Phylogenetic analysis of the B. longum core genome also provides evidence for a novel fifth B. longum subspecies. Finally, we improved genetic accessibility for the strain B. longum subsp. longum NCIMB 8809, which allowed the generation of a mutant of this strain.

Abstract
This commentary aims to extend the debate of the lead article authors (Wylie, McAllister, Davidson, and Marshall, 2013) by translating the nine recommendations of the World Report on Disability into a plan of action for the aphasia community. Solutions for the advancement of aphasia science and services are presented at international (macro), national (meso), and local (micro) levels. Implications for speech-language pathologists and aphasia service delivery are discussed. An overarching call to action is the need for speech-language pathologists to support a strong and vibrant aphasia community at all levels, so that the voices of people with aphasia can be heard.

Abstract
INTRODUCTION Adults sustain significant, often irreversible impairments following brain injury. The process they go through coming to terms with these impairments can seriously interfere with their readiness to engage in rehabilitation. AIM This study aimed to look beyond the development of self-awareness and insight in order to explore the concept of readiness as it relates to clients' experiences of engaging with therapy. METHOD Sixteen in-depth interviews were conducted with 14 adults with a moderate-severe traumatic brain injury (TBI) and nine of their significant others. These participants were asked to speak about the continuum of care they experienced and the factors that effected their engagement with care. RESULTS The results of this study indicated that participants believed their ability to engage in therapy was related to the degree to which they were aware of and accepted their impairments and motivated to engage in rehabilitation. Participants reported that the rate and degree to which they developed awareness varied according to the type of impairments they experienced (i.e. physical vs cognitive). Participants also stated that one way to augment their awareness was to compare their new vs old selves and to compare their recovery to those of others with a similar impairment. Finally, participants reported that it was important to be able to access services when they had accepted their impairment and were ready to engage in therapy. CONCLUSION The clinical implications for considering the degree of awareness of impairments and readiness for engagement in care of an adult with a moderate-severe TBI are discussed in relation to future services planning.

Abstract
Resource allocation and planning of future services is dependent on current volumes, making it imperative that procedural data is accurately recorded. We sought to evaluate the effectiveness of the information gathered by the Hospital Inpatient Enquiry (HIPE) system in recording such activity. Five index vascular procedures (open/endovascular abdominal aneurysm repair, carotid endarterectomy, lower limb angioplasty/bypass) were chosen to reflect activity. The Economic and Social Research Institute (ESRI), and HIPE databases were interrogated to obtain the regional and hospital specific figures for the years 2005, 2006 and 2009, and then compared with the prospective vascular database in St James's hospital. Data for 2006 (the most recent year available) shows significant discrepancies between the HIPE and vascular database figures for St James's hospital. The HIPE and database figures respectively for; open aneurysm 13/30 (-50%), endovascular aneurysm 39/31 (+25%), carotid 62/48 (+29%), angioplasty 242/111 (+100%) and bypass 24/10 (+100%) These inaccuracies are likely to be magnified on a regional and national level when pooling data.

Abstract
The objective of this study was to determine if increased overjet (greater than 6 mm) influences the magnitude and reproducibility of natural smile and maximal smile in Caucasian adult females. Twenty adult females with an increased overjet (6-10 mm) and 20 control adult females (overjet 2-4 mm) with no history of orthodontic treatment volunteered to participate. The mean age in the control group was 30.1 ± 6.4 years and the mean age in the test group was 31.9 ± 10.8 years. Three-dimensional stereophotogrammetric images were captured of each subject for three expressions: at rest, natural smile, and maximal smile. The images were recorded twice on two separate occasions, 6 weeks apart. Images were landmarked and a partial ordinary Procrustes superimposition was used to adjust for the differences in head posture between the same expressions. The magnitude of movement relative to the rest position, averaged over all the landmarks, was calculated and compared between the groups using analysis of variance (linear mixed-effects model); the intra- and inter-session reproducibility of both expressions was assessed. There was greater mean movement, averaged over all the landmarks, in the control group than in the increased overjet group for both natural smile and maximal smile (P = 0.0068). For these expressions, there were no statistically significant differences in reproducibility within sessions (P = 0.5403) or between sessions (P = 0.3665). Increased overjet had a statistically significant effect on the magnitude of smiling but did not influence the reproducibility of natural or maximal smile relative to controls.

Abstract
While antibiotics address the root cause of sepsis--that of pathogen infection--they fail to provide an adequate cure for the condition. Currently, 30% to 50% of septic patients die, and this figure is likely to increase in line with the proliferation of multi-drug resistant bacteria. With an increased understanding of the immune response, it has been proposed that modulation of this defence mechanism offers the best hope of cure. Many entry-points in the immune system have been identified and targeted therapies have been developed,but why are these not in routine clinical practice? This review examines the latest evidence for the use of immuno-modulating drugs, obtained from human clinical trials. We discuss cytokine-based therapies, steroids and anti-coagulants. Finally, consideration is given as to why successful therapies in the laboratory, and in vivo models, do not automatically translate into clinical benefit

Abstract
AIMS To study the effect of gluten-free diet on growth and diabetic control of children with type 1 diabetes mellitus and coeliac disease. METHODS Twenty one children (mean age 7.5 years, range 1.6-12.9) with type 1 diabetes, primarily initially identified on the basis of symptoms and consecutively diagnosed with coeliac disease by biopsy over a 10 year period, were matched by sex, age at onset, and duration of diabetes with two diabetic controls without coeliac disease. Weight, height, haemoglobin A1c, and insulin requirements were measured before and for 12 months after the diagnosis and treatment of coeliac disease. Dietary awareness and adherence were assessed by structured questionnaire. RESULTS A gluten-free diet resulted in a significant increase in weight-for-age z scores at 12 months after diagnosis (mean increase in z score 0.33) and in BMI (mean increase in z score 0.32). Increases in height did not achieve statistical significance. Controls showed no significant changes in weight, height, or BMI over the same period. Insulin dosage at diagnosis was less in coeliacs than in controls (mean difference 0.16 units/kg/day), but was similar to controls once a gluten-free diet had been established. Questionnaires were obtained in 20 patients. There appeared to be a relation between dietary awareness/adherence and growth parameters, but the small number of patients with "poor/fair" dietary adherence prevented meaningful analysis of this group. CONCLUSION Identification and dietary treatment of coeliac disease in children with diabetes improved growth and influenced diabetic control. Evaluation of the outcome of treatment of coeliac disease in diabetics should include assessments of gluten intake.

Abstract
Advanced or metastatic disease is common in both oesophagogastric and colorectal cancers, with poor 5-year survival despite palliative chemotherapy. We have investigated the sensitivity of gastrointestinal tumours to gemcitabine in combination with mitomycin C (GeM), using a modified ex vivo ATP-based tumour chemosensitivity assay (ATP-TCA). Tumour material from 41 colorectal and 22 oesophagogastric cancers were assessed. The GeM combination showed variable but definite activity in most of the samples tested. The results show that GeM achieves >95% inhibition at concentrations within the range achievable clinically in 60% of colorectal tumours (21 out of 35) and 38% of oesophagogastric tumours (five out of 13) tested. We did not identify any significant difference in sensitivity using concurrent or sequential exposure of tumour-derived cells to these two drugs. The results from this study suggest that GeM may be a useful combination in the treatment of advanced gastrointestinal malignancy.

Abstract
Testicular cancer is the commonest malignancy in young males and its incidence has more than doubled in the last 25 years. For clinical purposes, two tumour types are identified, seminoma and non-seminoma germ cell tumours (loosely known as teratomas). Stage I disease is confined to the testes and is managed surgically, with adjuvant chemotherapy or radiotherapy as appropriate. Cisplatin-based chemotherapy is the cornerstone of treatment for metastatic disease, with cure rates exceeding 80%. Early diagnosis and cure should be the aim in all patients. To this end, those with testicular symptoms should be evaluated promptly by ultrasound, and in young male patients presenting with the clinical picture of metastatic disease, germ cell tumour should top the list of differential diagnoses.

Abstract
BACKGROUND This study was designed to evaluate the efficacy and toxicity of a 12-week alternating weekly chemotherapy regimen for advanced Hodgkin's disease. Consolidative irradiation of residual masses was used in selected cases. PATIENTS AND METHODS Eighty-three patients with newly diagnosed advanced Hodgkin's disease (bulky stage IIA, stage IIB-IVB) or with progressive disease after extended field radiotherapy for early stage disease were included in this study. The patients were treated for 12 weeks with PACE BOM comprising oral prednisolone together with intravenous doxorubicin, cyclophosphamide and etoposide alternating weekly with intravenous bleomycin, vincristine and methotrexate. Limited field adjuvant radiotherapy was also given to 21 patients with localised persistent radiological abnormalities visible on chest X-ray after chemotherapy. The study end points were overall survival, failure free survival (FFS) and toxicity, particularly with respect to reproductive function. RESULTS With a median post treatment follow up of 52 months the actuarial 5-year overall survival is 90% (confidence interval 81%-95%) and FFS is 64% (52%-74%). This treatment was well tolerated and fertility was maintained in a high proportion of young adults. CONCLUSIONS The brief duration PACE BOM regimen with or without radiotherapy appears to be comparable in efficacy to other doxorubicin containing regimens, with a favourable toxicity profile. Randomised clinical trials are now needed to evaluate the role of this and comparable initial treatment approaches to advanced Hodgkin's disease.

Abstract
A 15 year old boy with sickle cell disease developed intrahepatic cholestasis. A course of exchange transfusion successfully corrected the extreme hyperbilirubinaemia over one year. Upon stopping the exchange transfusion programme the hyperbilirubinaemia relapsed but transfusion was effective when reinstituted.

Abstract
Mechanically skinned, single muscle fibers, isometrically activated in pH and Ca2+ (Sr2+) buffered solutions were used to examine the function of the contractile apparatus in slow- and fast-twitch fibers from soleus (SOL, predominantly slow-twitch) and extensor digitorum longus (EDL, predominantly fast-twitch) muscles of streptozotocin (STZ)-induced diabetic rats and age-matched controls. Three and 14 days after STZ administration, the contractile properties of muscle fibers from diabetic rats did not differ significantly from those of controls with respect to several mechanical parameters, such as maximum Ca-activated tension, activation threshold, and sensitivity to Ca2+ and Sr2+. In contrast, 28 days after STZ administration, 37.5% of the fast-twitch EDL fibers developed maximum activated tensions (77.1 +/- 10.4 kN/m2), which were significantly lower than those developed by controls (244.0 +/- 14.3 kN/m2), and the slow-twitch SOL fibers displayed a significantly higher sensitivity to Ca2+ (and Sr2+) than the controls. All fibers from diabetic rats, including the low-tension EDL fibers and higher Ca sensitivity SOL fibers displayed control-like electrophoretic profiles of the major myofibrillar proteins. Taken together with data from earlier studies on the effects of long-term diabetes on whole skeletal muscle contractility, these results strongly suggest that 1) the decrease in tetanic tension output of EDL muscles induced by diabetes is caused mainly by direct effects of the diabetic condition on the contractile/regulatory system of a subpopulation of fast-twitch fibers, which develop little force, and 2) the diabetes-induced slowing of twitch times of SOL muscles is caused in part by the increased sensitivity to Ca2+ of the contractile apparatus in the slow-twitch fibers.
