Abstract
Anaesthetic practice contributes to climate change. Volatile capture technology, typically based on adsorption to a carbon- or silica-based substrate, has the potential to mitigate some of the harmful effects of using halogenated hydrocarbons. Anaesthetists have a professional responsibility to use anaesthetic agents which offer the greatest safety and clinical benefit with the lowest financial cost and environmental impacts. Inhalational anaesthetics should be used at an appropriate concentration with a minimal fresh gas flow via a circle system to minimise unnecessary waste. Once practice efficiencies have been maximised, only then should technical solutions such as volatile capture be employed. In this narrative review, we focus on the available literature relating to volatile capture technology, obtained via a targeted literature search and through contacting manufacturers and researchers. We found six studies focusing on the Blue-Zone Technologies Deltasorb®, SageTech Medical SID and Baxter/ZeoSys CONTRAfluran™ volatile capture systems. Though laboratory analyses of available systems suggest that > 95% in vitro mass transfer is possible for all three systems, the in vivo results for capture efficiency vary from 25% to 73%. Currently, there is no financial incentive for healthcare organisations to capture waste anaesthetic gases, and so the value of volatile capture technology requires quantification. System-level organisations, such as Greener NHS, are best positioned to commission such evaluations and make policy decisions to guide investment. Further research using volatile capture technology in real-world settings is necessary and we highlight some priority research questions to improve our understanding of the utility of this group of technologies.

Abstract
Median sternotomy is widely recognised as the primary incision technique in cardiac surgery. This surgical procedure involves dividing the sternum to gain access to the heart and lungs, making it invaluable in correcting congenital heart defects. Furthermore, it is frequently employed in adult patients, particularly during coronary artery bypass graft (CABG) procedures. In this imaging review, we present a comprehensive overview of the pre-procedural assessment and various post-sternotomy complications encountered within our clinical experience at a tertiary cardiothoracic centre. The focus of this review is to outline the imaging features associated with mediastinal adhesions and establish the minimal safe distance between the sternum and common mediastinal structures when considering re-sternotomy. By providing visual examples, we aim to facilitate a better understanding of these key concepts. Moreover, we delve into a detailed discussion of a spectrum of postoperative complications that may arise following median sternotomy including those related to metalwork (sternal wire fracture), bone (sternal dehiscence, non-union and osteomyelitis), and soft tissue (abscess, haematoma).

Abstract
OBJECTIVE To provide updated estimates of childhood cancer incidence and survival in Aotearoa, New Zealand. METHOD Registrations for children under the age of 15 years diagnosed with cancer between 2010 and 2019 were extracted from the New Zealand Children's Cancer Registry. Cases were stratified by age, sex, prioritised ethnicity (Māori, Pacific peoples, and non-Māori) and cancer type. Age-standardised incidence rates (ASRs) per million person years and observed survival rates were calculated. RESULTS During the study period, 1522 children were diagnosed with cancer providing an ASR of 169.1 per million per year (95 % Confidence Interval, CI: 157.0-181.2). For all childhood cancers combined, survival at 5-years was 85.6 % (95 % CI 83.7-87.3). There was a gap in 5-year survival between Māori (80.9 %, 95 % CI 76.5-84.6), Pacific peoples (82.6 %, 95 % CI 75.6-87,7) and Non-Māori (87.8 %, 95 % CI 85.6-89.7) In both adjusted and unadjusted models, this difference in survival was most marked (p < 0.05) among children who were 10-14 years of age at diagnosis. CONCLUSION Childhood cancer incidence and survival rates in Aotearoa, New Zealand remain comparable to other high-income countries. Further research is required to understand the survival difference between ethnic groups.

Abstract
We measure different contributions to entropy production in a living functional epithelial tissue. We do this by extracting the functional dynamics of development while at the same time quantifying fluctuations. Using the translucent Drosophila melanogaster pupal epithelium as an ideal tissue for high-resolution live imaging, we measure the entropy associated with the stochastic geometry of cells in the epithelium. This is done using a detailed analysis of the dynamics of the shape and orientation of individual cells which enables separation of local and global aspects of the tissue behavior. Intriguingly, we find that we can observe irreversible dynamics in the cell geometries but without a change in the entropy associated with those degrees of freedom, showing that there is a flow of energy into those degrees of freedom. Hence, the living system is controlling how the entropy is being produced and partitioned into its different parts.

Abstract
Acute abdominal pain in pregnancy poses a significant diagnostic challenge. The differential diagnosis is wide, clinical assessment is difficult, and the use of conventional imaging methods is restricted due to risks to the fetus. This can lead to delay in diagnosis, which increases the risk of maternal and fetal harm. Imaging techniques not involving ionising radiation are preferred. Sonography remains first line, but anatomical visualisation can be limited due to displacement of adjacent structures by the gravid uterus. MRI provides excellent cross-sectional soft-tissue assessment of the abdomen and pelvis, and no study to date has demonstrated significant deleterious effects to the fetus at any gestation; however, there remains a theoretical risk of tissue heating by radiofrequency pulses, and there must be consideration of benefit versus potential risk for any use of magnetic resonance imaging (MRI) in pregnancy. With a limited protocol of sequences, a broad spectrum of pathologies can be evaluated. Computed tomography carries the highest exposure of ionising radiation to the fetus, but may be necessary, particularly in cases of trauma. The patient must be kept informed and any potential risks to the patient and fetus should be clearly explained. We present a radiological decision-making tool to guide choice of imaging and best establish the underlying diagnosis in the acute pregnant abdomen. In addition, using illustrative examples from our practice at a large tertiary centre, we review the advantages and disadvantages of each imaging method, with particular focus on the utility of MRI.

Abstract
Background The effectiveness of laparoscopic ventral mesh rectopexy (LVMR) in patients with defecatory disorders secondary to internal rectal prolapse is poorly evidenced. A UK-based multicenter randomized controlled trial was designed to determine the clinical efficacy of LVMR compared to controls at medium-term follow-up. Methods The randomized controlled trial was conducted from March 1, 2015 TO January 31, 2019. A stepped-wedge RCT design permitted observer-masked data comparisons between patients awaiting LVMR (controls) with those who had undergone surgery. Adult participants with radiologically confirmed IRP refractory to conservative treatment were randomized to three arms with different delays before surgery. Efficacy outcome data were collected at equally stepped time points (12, 24, 36, 48, 60, and 72 weeks). Clinical efficacy of LVMR compared to controls was defined as ≥ 1.0-point reduction in Patient Assessment of Constipation-Quality of Life and/or Symptoms (PAC-QOL and/or PAC-SYM) scores at 24 weeks. Secondary outcome measures included 14-day diary data, the Generalized Anxiety Disorder scale (GAD-7), the Patient Health Questionnaire-9 (PHQ-9), St Marks incontinence score, the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12), the chronic constipation Behavioral Response to Illness Questionnaire (CC-BRQ), and the Brief Illness Perception Questionnaire (BIPQ). Results Of a calculated sample size of 114, only 28 patients (100% female) were randomized from 6 institutions (due mainly to national pause on mesh-related surgery). Nine were assigned to the T0 arm, 10 to T12, and 9 to T24. There were no substantial differences in baseline characteristics between the three arms. Compared to baseline, significant reduction (improvement) in PAC-QOL and PAC-SYM scores were observed at 24 weeks post-surgery (– 1.09 [95% CI – 1.76, – 0.41], p = 0.0019, and – 0.92 [– 1.52, – 0.32], p = 0.0029, respectively) in the 19 patients available for analysis (9 were excluded for dropout [n = 2] or missing primary outcome [n = 7]). There was a clinically significant long-term reduction in PAC-QOL scores (− 1.38 [− 2.94, 0.19], p = 0.0840 at 72 weeks). Statistically significant improvements in PAC-SYM scores persisted to 72 weeks (− 1.51 [− 2.87, − 0.16], p = 0.0289). Compared to baseline, no differences were found in secondary outcomes, except for significant improvements at 24 and 48 weeks on CC-BRQ avoidance behavior (− 14.3 [95% CI − 23.3, − 5.4], and − 0.92 [− 1.52, − 0.32], respectively), CC-BRQ safety behavior (− 13.7 [95% CI − 20.5, − 7.0], and − 13.0 [− 19.8, − 6.1], respectively), and BIPQ negative perceptions (− 16.3 [95% CI − 23.5, − 9.0], and − 10.5 [− 17.9, − 3.2], respectively). Conclusions With the caveat of under-powering due to poor recruitment, the study presents the first randomized trial evidence of short-term benefit of LVMR for internal rectal prolapse. Trial registration ISRCTN Registry (ISRCTN11747152). Supplementary Information The online version contains supplementary material available at 10.1007/s10151-022-02633-w.

Abstract
AIM To establish common patterns of injury in vascular bowel and mesenteric injury (VBMI) and to identify any factors that may lead to delayed treatment. METHODS AND MATERIALS Forty-one patients with blunt VBMI presented to the level 1 trauma centre of the The Royal London Hospital over 5 years. Computed tomography (CT) images were reviewed to identify the specific location of injury and additional features such as seatbelt bruising and lumbar hernias. Surgical reports were reviewed to record any pertinent surgical findings at laparotomy. RESULTS The commonest mechanism of injury was a restrained car occupant involved in a road traffic collision (49%, n=20). The ileocaecal mesenteric vasculature was most frequently injured (41.5%, n=17), followed by the mid ileum (17.1%, n=7). Seatbelt bruising was identified in 80% of restrained car occupants and lumbar hernias in 22% of all patients with VBMI. CONCLUSION Restrained car occupants involved in road traffic collisions are at increased risk of VBMI with particular susceptibility of the ileocaecal mesentery. This has implications for the reporting radiologist and trauma surgeon in deciding which patients require careful monitoring for the development of delayed bowel ischaemia.

Abstract
Abstract
To meet federal and state regulatory needs, a liquid chromatographic (LC) method with ultraviolet (UV) detection was developed for determination of 7 tetracyclines at 30 ng/mL in milk. Raw milk samples are defatted, acidified, and centrifuged to remove proteins, and tetracyclines are specifically absorbed from the milk by chelation with metal ions bound to small Chelating Sepharose Fast Flow columns. Tetracyclines are removed from these columns with EDTA-containing buffer, and extracts are further cleaned by ultrafiltration. Finally, extracts are concentrated and analyzed simultane ously by using on-line concentration. This method was validated in a collaborative study that involved 11 laboratories, including the authors’ laboratory. Each laboratory was asked to prepare and analyze known control and fortified milk samples, as well as 18 coded blind samples. Eight laboratories completed all analyses. Average interlaboratory recoveries for the known fortified samples ranged from 59% (methacycline at 15 ng/mL) to 78% (oxytetracy cline at 60 ng/mL). Average recovery for each of 7 residues at 30 ng/mL were between 60 and 110%, meeting single-residue guidelines for accuracy set by the U.S. Food and Drug Administration. Reproducibility relative standard deviation (RSDR) for the known fortified samples varied from 11 to 39%, with 6 of 7 residues at the 30 ng/mL level having RSDR values at or below 20%. Seven of 8 laboratories correctly identified blind control milk samples and all 28 residues present in blind samples. The metal chelate affinity—LC method for determination of multiple tetracycline residues in milk has been adopted first action by AOAC INTERNATIONAL.

Abstract
Background: There are huge international disparities in childhood cancer survival. The International Agency for Research on Cancer's Global Initiative for Cancer Registry Development has improved cancer registry coverage of the world's population, particularly in low- and middle-income countries (LMICs). However, for virtually all registries around the world, the challenge remains of collecting comparable and population-wide information on stage at diagnosis. This information is essential to understand and address disparities in outcomes. In response to this, a UICC-endorsed set of consensus guidelines for assigning stage for 16 of the most common types of childhood cancer was recently developed (the Toronto Guidelines), for use by population registries in both high and LMICs. Aim: To trial the Toronto Guidelines on a population-basis, and develop a structured protocol, suitable for global implementation, for collecting the required data elements and assigning cancer stage at diagnosis for childhood cancer. Methods: Using an innovative approach, data items as defined in the Toronto Guidelines were gathered from the medical record and entered electronically. Stage at diagnosis was assigned automatically using computer algorithms, thus reducing errors and maximizing consistency. Data collection and assignment of stage were incorporated into an online platform that was then trialed in the national childhood cancer registries of Australia and New Zealand for cases diagnosed between 2006 and 2014. Results: Stage at diagnosis was successfully assigned for 94% of all eligible patients (n=1662) across both countries. In contrast, stage as recorded by the treating clinician was located in the medical record for only 39% of cases in Australia. Conclusion: Practical implementation of the Toronto Guidelines has been highly successful to date and further testing is planned in LMICs. This approach has the potential to improve global epidemiologic monitoring of childhood cancer and lead to better understanding of the reasons underlying disparities in outcome.

Abstract
IntroductionAddressing the interaction between mental and physical health to provide more integrated healthcare has been highlighted as an international priority for health and education systems. Educational interventions focusing on multi-disciplinary, interprofessional approaches to integrated mental and physical healthcare are an essential part of transforming health systems. Simulation training is one tool by which such training can be delivered, in contrast to traditional teaching methods. However, simulation training can be high-cost and clarity over the impact is required.AimTo compare simulation training for integrating mental and physical health to role-play and didactic teaching, on their effect on confidence, knowledge, and attitudes of participants.MethodsParticipants in simulation training (n = 24) and role play plus didactic teaching (n = 87) both completed self-report measures of confidence and knowledge in working with mental and physical health needs, as well as the Readiness for interprofessional learning scale (RIPLS) collecting attitudes towards interprofessional collaboration. All participants also completed post-course qualitative feedback form with open questions.ResultsT-tests found statistically significant increases in confidence and knowledge following both educational interventions. T-tests showed statistically significant increases in attitudes to interprofessional collaboration (RIPLS) following simulation training, while there were no statistically significant changes after role-play and didactic teaching. Thematic analyses of post-course open questions demonstrated differing learning outcomes.ConclusionsSimulation training appears to have a different and beneficial impact to role play and didactic teaching alone, when training participants on integrating mental and physical health.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionSimulation training has the potential to develop communication and teamwork skills, as well as technical knowledge and competency. Mental health simulation training aims to promote awareness of mental health conditions and to enhance human factors (or non-technical) skills that will enable professionals that work in mental and physical healthcare settings to improve their collaborative and patient-centered clinical practice. This study explored the differences in learning outcomes after a mental health simulation course between different professionals–nursing staff, medical staff, and allied health professionals.Aims and objectives This project examined the different learning outcomes of human factors, confidence and knowledge, for nursing, medical and allied health professionals following mental health simulation training.MethodsCourse-specific measures of confidence and knowledge were administered pre- and post-training to all participants, in addition to The Human Factors Skills for Healthcare Instrument (HFSHI). A post-course evaluation for with free-text responses to open questions regarding the impact of the training was utilised to collect qualitative data.ResultsWith data collection ongoing, preliminary results indicate differences in learning outcome depending on professional background, both in terms of quantitative measures and qualitative findings.ConclusionsLearning outcomes may differ for different professionals despite receiving the same simulation training focusing on mental and physical health, evidencing the importance of sharing individual learning experiences in simulation using a debrief model.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
INTRODUCTION This study reports long-term patient reported urinary function and urinary-related quality of life (uQoL) after external beam radiotherapy (EBRT) for localized prostate cancer. METHODS 574 men underwent definitive prostate EBRT to 70-78 Gy±androgen deprivation therapy between 2000 and 2009. The median follow-up from EBRT was 44 months. Patients were evaluated at baseline (pre-EBRT) and at intervals post-treatment using the International Prostate Symptom Score (IPSS) instrument. RESULTS Patients with mild IPSS at baseline (total 0-7) reported median total scores of 3, 4 and 3 at baseline, 6 and 48 months respectively post-EBRT. For patients with moderate IPSS at baseline (total 8-19), median total IPSS was 12 at baseline and 9 at both 6 and 48 months. For the severe IPSS group at baseline (total 20-35), the median total IPSS was 24, 12 and 14 at baseline, 6 and 48 months post-EBRT. The cumulative risk of persistent IPSS increase (greater than 5 points above baseline) at 48 months was 16%, 10% and 6% for patients with mild, moderate and severe baseline IPSS respectively. 94%, 54% and 11% of patients with mild, moderate and severe baseline IPSS reported good uQoL at baseline respectively, with these proportions increasing to 95%, 83% and 69% at 48 months. CONCLUSION Urinary symptoms and uQoL as measured by the IPSS instrument remained stable or improved for the majority of men after definitive EBRT with or without ADT for prostate cancer. This was especially notable for the group of men with worse baseline symptoms or uQoL, with risk of persistent worsening of urinary symptoms decreasing with higher baseline IPSS category. Understanding the expected pattern of urinary symptoms and related uQoL in the months and years following EBRT taking into account baseline urinary function is highly valuable for counselling men as part of the therapeutic decision-making process.

Abstract
AIM To determine the potential effect of changes to the National Institute for Health and Care Excellence (NICE) guidelines to the use of computed tomography (CT) in the assessment of suspected paediatric cervical spine (c-spine) injury. MATERIAL AND METHODS A 5 year retrospective study was conducted of c-spine imaging in paediatric (<10 years) patients presenting following blunt trauma at a Level 1 trauma centre in London. All patients under the age of 10 years who underwent any imaging of the c-spine following blunt trauma were included. Clinical data relating to the presenting signs and symptoms were obtained from the retrospective review of electronic records and paper notes. This was then applied to the previous NICE guideline (CG56) and to the new NICE guideline (CG176). Patients with incomplete data were excluded. RESULTS Two hundred and seventy-eight patients <10 years underwent imaging of the c-spine following blunt trauma. Two hundred and seventy (97.12%) examinations had complete data and were included in further analysis. One hundred and forty-nine (55.19%) met the criteria for a CT of the c-spine under NICE CG56, whereas 252 (93.33%) met the updated NICE CG176 criteria for c-spine CT. Five (1.85%) patients had a c-spine injury and met the criteria under both CG56 and CG176 NICE guidelines. CONCLUSION Recent changes to NICE Head Injury Guidelines relating to radiological assessment of paediatric c-spine following blunt trauma are likely to result in an increased usage of CT as the initial radiological investigation over plain radiographs, without an apparent increase in specificity in the present series.

Abstract
A pilot randomized controlled trial that evaluated the effect of remote ischemic preconditioning (RIPC) on clinical outcomes following major vascular surgery was performed. Eligible patients were those scheduled to undergo open abdominal aortic aneurysm repair, endovascular aortic aneurysm repair, carotid endarterectomy, and lower limb revascularization procedures. Patients were randomized to RIPC or to control groups. The primary outcome was a composite clinical end point comprising any of cardiovascular death, myocardial infarction, new-onset arrhythmia, cardiac arrest, congestive cardiac failure, cerebrovascular accident, renal failure requiring renal replacement therapy, mesenteric ischemia, and urgent cardiac revascularization. Secondary outcomes were components of the primary outcome and myocardial injury as assessed by serum troponin values. The primary outcome occurred in 19 (19.2%) of 99 controls and 14 (14.1%) of 99 RIPC group patients ( P = .446). There were no significant differences in secondary outcomes. Our trial generated data that will guide future trials. Further trials are urgently needed.

Abstract
There is limited research around how mental health (MH) student nurses interpret and differentiate between people's religious and cultural beliefs and the existence of psychopathological symptomatology and experiences. Here we focus on one cultural issue that arose from research exploring how MH student nurses approach and interpret religion and culture in their practice - that is, the difficulties in determining the clinical significance of the religious beliefs and experiences expressed by the people they care for. While problems with establishing the cultural boundaries of normality in clinical assessments are an important area of debate in cultural psychiatry, it remains a peripheral issue in MH nurse education. An anthropologically informed qualitative research design underpinned 'critical incident' (CI)-focused ethnographic interviews with 36 second and third-year MH nursing field students and seven undergraduate MH branch lecturers. Follow up focus groups were also carried out. Interview transcripts were subject to thematic analysis. Four subthemes were identified under the broad theme of the clinical significance of religious-type expression and experience: (1) identifying the difference between delusions and religious belief; (2) identifying whether an experience was hallucination or religious experience; (3) the clinical implications of such challenges; and (4) applying religion-specific knowledge. There are clinical implications that may result from the difficulties with assessing the clinical significance of religious beliefs and experiences, identified in both our research and within international cultural psychiatry literature and research. Misinterpretation and therefore wrongly assessing someone's experience as pathological is a significant concern. It is suggested that CI analysis could be adapted to help nurses, nursing students and nurse educators recognize the religious dimensions of mental distress, particularly those that then potentially impact upon the accuracy and person centeredness of clinical assessment. Further research is proposed to investigate the clinical assessment and training needs of nurses in the area of religion and mental distress.

Abstract
Background Self-harm is a significant public health concern in the UK. This is reflected in the recent addition to the English Public Health Outcomes Framework of rates of attendance at Emergency Departments (EDs) following self-harm. However there is currently no source of data to measure this outcome. Routinely available data for inpatient admissions following self-harm miss the majority of cases presenting to services. We aimed to investigate (i) if a dataset of ED presentations could be produced using a combination of routinely collected clinical and administrative data and (ii) to validate this dataset against another one produced using methods similar to those used in previous studies. Methods Using the Clinical Record Interactive Search system, the electronic health records (EHRs) used in four EDs were linked to Hospital Episode Statistics to create a dataset of attendances following self-harm. This dataset was compared with an audit dataset of ED attendances created by manual searching of ED records. The proportion of total cases detected by each dataset was compared. Results There were 1932 attendances detected by the EHR dataset and 1906 by the audit. The EHR and audit datasets detected 77 % and 76 % of all attendances respectively and both detected 82 % of individual patients. There were no differences in terms of age, sex, ethnicity or marital status between those detected and those missed using the EHR method. Both datasets revealed more than double the number of self-harm incidents than could be identified from inpatient admission records. Conclusions It was possible to use routinely collected EHR data to create a dataset of attendances at EDs following self-harm. The dataset detected the same proportion of attendances and individuals as the audit dataset, proved more comprehensive than the use of inpatient admission records, and did not show a systematic bias in those cases it missed.

Abstract
Children with acute lymphoblastic leukemia (ALL) and high minimal residual disease (MRD) levels after initial chemotherapy have a poor clinical outcome. In this prospective, single arm, Phase 2 trial, 111 Dutch and Australian children aged 1-18 years with newly diagnosed, t(9;22)-negative ALL, were identified among 1041 consecutively enrolled patients as high risk (HR) based on clinical features or high MRD. The HR cohort received the AIEOP-BFM (Associazione Italiana di Ematologia ed Oncologia Pediatrica (Italy)-Berlin-Frankfurt-Münster ALL Study Group) 2000 ALL Protocol I, then three novel HR chemotherapy blocks, followed by allogeneic transplant or chemotherapy. Of the 111 HR patients, 91 began HR treatment blocks, while 79 completed the protocol. There were 3 remission failures, 12 relapses, 7 toxic deaths in remission and 10 patients who changed protocol due to toxicity or clinician/parent preference. For the 111 HR patients, 5-year event-free survival (EFS) was 66.8% (±5.5) and overall survival (OS) was 75.6% (±4.3). The 30 patients treated as HR solely on the basis of high MRD levels had a 5-year EFS of 63% (±9.4%). All patients experienced grade 3 or 4 toxicities during HR block therapy. Although cure rates were improved compared with previous studies, high treatment toxicity suggested that novel agents are needed to achieve further improvement.

Abstract
X-linked chronic granulomatous disease (X-CGD) is an inherited immunodeficiency with absent phagocyte NADPH oxidase activity caused by defects in the gene encoding gp91phox. Here we evaluated strategies for less intensive conditioning for gene therapy of genetic blood disorders without selective advantage for gene correction, such as might be used in a human X-CGD protocol. We compared submyeloablative with ablative irradiation as conditioning in murine X-CGD, examining engraftment, oxidase activity and vector integration in mice transplanted with marrow transduced with a gamma-retroviral vector for gp91phox expression. The frequency of oxidase-positive neutrophils in the donor population was unexpectedly higher in many 300 cGy-conditioned mice compared to lethally irradiated recipients, as was the fraction of vector-marked donor secondary CFU-S12. Vector integration sites in marrow, spleen, and secondary CFU-S12 DNA from primary recipients were enriched for cancer-associated genes, including Evi1, and integrations in or near cancer-associated genes were more frequent in marrow and secondary CFU-S12 from 300 cGy-conditioned mice compared to fully ablated mice. These findings support the concept that vector integration can confer a selection bias, and suggest that intensity of the conditioning regimen may further influence the effects of vector integration on clonal selection in post-transplant engraftment and hematopoiesis.

Abstract
INTRODUCTION The tumour microenvironment is hypoglycaemic, hypoxic and acidotic. This activates a stress signalling pathway: the unfolded protein response (UPR). The UPR is cytoprotective if the stressor is mild, but may initiate apoptosis if severe.Activation of the UPR in breast carcinoma is induced by microenvironmental stress such as glucose and oxygen deprivation, but may also be linked to oestrogen stimulation. It may be clinically significant as it may alter chemosensitivity to doxorubicin. METHODS 395 human breast adenocarcinomas were immunohistochemically stained for UPR activation markers (glucose-regulated protein (GRP-78 and XBP-1). A model of UPR activation in vitro by glucose deprivation of T47D breast cancer cells was developed to determine how the UPR affects cellular sensitivity to doxorubicin and 5-fluorouracil. Cytotoxicity was assessed using a colorimetric cytotoxicity assay (MTT). The effect of oestrogen stimulation and tamoxifen exposure on UPR activation by T47D cells was determined by western blotting measurement of the key UPR protein, GRP-78. RESULTS Expression of GRP78 and XBP-1 was demonstrated in 76% and 90% of the breast cancers, respectively, and correlated with oestrogen receptor positivity (P=0.045 and 0.017, respectively). In vitro UPR activation induced resistance to both doxorubicin and 5-flurouracil, (P<0.05). Oestrogen stimulation induced GRP78 and XBP1 over-expression on western blotting. Tamoxifen did not block this response and may induce UPR activation in its own right. CONCLUSIONS The UPR is activated in the majority of breast cancers and confers resistance to chemotherapy. In vitro oestrogen stimulates UPR induction. UPR activation may contribute to breast cancer chemoresistance and interact with oestrogen response elements.

Abstract
Research in gene therapy involving genome-integrating vectors now often includes analysis of vector integration sites across the genome using methods such as ligation-mediated PCR (LM-PCR) or linear amplification-mediated PCR (LAM-PCR). To help researchers analyze these sites and the functions of nearby genes, we have developed SeqMap (http://seqmap.compbio.iupui.edu/) a secure, web-based comprehensive vector integration site management tool that automatically analyzes and annotates large numbers of vector integration sites derived from LM-PCR experiments in human and model organisms upon a common genome database. We believe the use of this resource will enable better reproducibility and understanding of this important data.

Abstract
BACKGROUND Urinary incontinence can affect 40-60% of people admitted to hospital after a stroke, with 25% still having problems on hospital discharge and 15% remaining incontinent at one year. OBJECTIVES To determine the optimal methods for treatment of urinary incontinence after stroke in adults. SEARCH STRATEGY We searched the Cochrane Incontinence and Stroke Groups specialised registers (searched 15 March 2007 and 5 March 2007 respectively), CINAHL (January 1982 to January 2007), national and international trial databases for unpublished data, and the reference lists of relevant articles. SELECTION CRITERIA Randomised or quasi-randomised controlled trials evaluating the effects of interventions designed to promote continence in people after stroke. DATA COLLECTION AND ANALYSIS Data extraction and quality assessment were undertaken by two reviewers working independently. Disagreements were resolved by a third reviewer. MAIN RESULTS Twelve trials with a total of 724 participants were included in the review. Participants were from a mixture of settings, age groups and phases of stroke recovery. BEHAVIOURAL INTERVENTIONS: Three trials assessed behavioural interventions, such as timed voiding and pelvic floor muscle training. All had small sample sizes and confidence intervals were wide. SPECIALISED PROFESSIONAL INPUT INTERVENTIONS: Two trials assessed variants of professional input interventions. Results tended to favour the intervention groups: in a small trial in early rehabilitation, fewer people had incontinence at discharge from hospital after structured assessment and management than in a control group (1/21 vs. 10/13; RR 0.06, 95% CI 0.01 to 0.43); in the second trial, assessment and management by Continence Nurse Advisors was associated with fewer participants having urinary symptoms (48/89 vs. 38/54; RR 0.77, 95% CI 0.59 to 0.99) and statistically significantly more being satisfied with care. COMPLEMENTARY THERAPY INTERVENTIONS: Three small trials all reported fewer participants with incontinence after acupuncture therapy (overall RR 0.44; 95% 0.23 to 0.86), but there were particular concerns about study quality. PHARMACOTHERAPY AND HORMONAL INTERVENTIONS: There were three small trials that included groups allocated meclofenoxate, oxybutinin or oestrogen. There were no apparent differences other than in the trial of meclofenoxate where fewer participants had urinary symptoms in the active group than in the control group (9/40 vs. 27/40; RR 0.33, 95% CI 0.18 to 0.62). AUTHORS' CONCLUSIONS Data from the available trials are insufficient to guide continence care of adults after stroke. However, there was suggestive evidence that professional input through structured assessment and management of care and specialist continence nursing may reduce urinary incontinence and related symptoms after stroke. Better quality evidence is required of the range of interventions that have been suggested for continence care after stroke.

Abstract
BACKGROUND The prognosis of well-differentiated thyroid cancer has been stratified into low- and high-risk groups. These risk groups can be used to predict prognosis and to guide treatment. METHODS Retrospective study of 962 patients with well-differentiated thyroid cancer treated from 1940 to 1998. Stratification into low- and high-risk groups based on age, metastases, extent, and size (AMES). Effects on survival of surgery, lymph node dissection, and radiation therapy were examined. RESULTS Seven hundred twenty-eight cases were papillary and 234 were follicular carcinoma. Seven hundred-fifty cases were low risk and 207 high risk. Twenty-year survival was 97.4% in the low-risk patients and 54.0% in high-risk patients (P < 0.001); it was 63.2% in the younger high-risk group and 41.0% in the older high-risk group (P < 0.001). Older high-risk patients had a survival advantage with bilateral thyroidectomy. Extent of surgery did not change survival in either the younger high-risk group or the low-risk group. Lymph node dissection and radioactive iodine ablation did not have an impact on survival. DISCUSSION Well-differentiated thyroid cancer in low-risk patients has a favorable outcome regardless of treatment. Low-risk patients can be safely treated with unilateral thyroidectomy alone. Risk stratification with a modification of the AMES criteria can be used to guide treatment.

Abstract
BACKGROUND Urinary incontinence can affect 40-60% of people admitted to hospital after a stroke, with 25% still having problems on hospital discharge and around 15% remaining incontinent at one year. OBJECTIVES To determine the optimal methods for prevention and treatment of urinary incontinence after stroke in adults. SEARCH STRATEGY We searched the Cochrane Incontinence and Stroke Groups specialised registers (searched 15 December 2004 and 26 October 2004, respectively), CINAHL (January 1982 to November 2004), national and international trial databases for unpublished data, and the reference lists of relevant articles. SELECTION CRITERIA Randomised or quasi-randomised controlled trials evaluating the effects of interventions designed to promote continence in people after stroke. DATA COLLECTION AND ANALYSIS Data extraction and quality assessment were undertaken by two reviewers working independently. Disagreements were resolved by a third reviewer. MAIN RESULTS Seven trials with a total of 399 participants were included in the review. Participants were from a mixture of settings, age groups and phases of stroke recovery. No two trials addressed the same comparison. Four trials tested an intervention against usual care, including acupuncture, timed voiding, and two types of specialist professional intervention. One cross-over trial tested an intervention (oestrogen) against placebo. One trial tested a specific intervention (oxybutynin) against another intervention (timed voiding), and one trial tested a combined intervention (sensory-motor biofeedback plus timed voiding) against a single component intervention (timed voiding alone). Reported data were insufficient to evaluate acupuncture or timed voiding versus usual care, oxybutynin versus timed voiding, or sensory motor biofeedback plus timed voiding versus usual care. Evidence from a single small trial suggested that structured assessment and management of care in early rehabilitation may reduce the number of people with incontinence at hospital discharge (1/21 versus 10/13; RR 0.06, 95% CI 0.01 to 0.43), and have other benefits. Evidence from another trial suggested that assessment and management of care by Continence Nurse Practitioners in a community setting may reduce the number of urinary symptoms (48/89 versus 38/54; RR 0.77, 95% CI 0.59 to 0.99), and increase satisfaction with care. AUTHORS' CONCLUSIONS There was suggestive evidence that specialist professional input through structured assessment and management of care and specialist continence nursing may reduce urinary incontinence after stroke. Data from trials of other physical, behavioural, complementary and anticholinergic drug interventions are insufficient to guide continence care of adults after stroke.

Abstract
In vitro measurements of skin absorption are an increasingly important aspect of regulatory studies, product support claims, and formulation screening. However, such measurements are significantly affected by skin variability. The purpose of this study was to determine inter- and intralaboratory variation in diffusion cell measurements caused by factors other than skin. This was attained through the use of an artificial (silicone rubber) rate-limiting membrane and the provision of materials including a standard penetrant, methyl paraben (MP), and a minimally prescriptive protocol to each of the 18 participating laboratories. "Standardized" calculations of MP flux were determined from the data submitted by each laboratory by applying a predefined mathematical model. This was deemed necessary to eliminate any interlaboratory variation caused by different methods of flux calculations. Average fluxes of MP calculated and reported by each laboratory (60 +/- 27 microg cm(-2) h(-1), n = 25, range 27-101) were in agreement with the standardized calculations of MP flux (60 +/- 21 microg cm(-2) h(-1), range 19-120). The coefficient of variation between laboratories was approximately 35% and was manifest as a fourfold difference between the lowest and highest average flux values and a sixfold difference between the lowest and highest individual flux values. Intralaboratory variation was lower, averaging 10% for five individuals using the same equipment within a single laboratory. Further studies should be performed to clarify the exact components responsible for nonskin-related variability in diffusion cell measurements. It is clear that further developments of in vitro methodologies for measuring skin absorption are required.

Abstract
It is well known that pulselike solutions of the cubic complex Ginzburg-Landau equation are unstable but can be stabilized by the addition of quintic terms. In this paper we explore an alternative mechanism where the role of the stabilizing agent is played by the parametric driver. Our analysis is based on the numerical continuation of solutions in one of the parameters of the Ginzburg-Landau equation (the diffusion coefficient c), starting from the nonlinear Schrödinger limit (for which c=0). The continuation generates, recursively, a sequence of coexisting stable solutions with increasing number of humps. The sequence "converges" to a long pulse which can be interpreted as a bound state of two fronts with opposite polarities.

Abstract
BACKGROUND Although gastrointestinal symptoms occur frequently, there is no validated measure of gastrointestinal symptoms in patients with diabetes mellitus. AIM To develop the Diabetes Bowel Symptom Questionnaire. METHODS A questionnaire derived from previously validated symptom measures was compiled to assess all relevant gastrointestinal and diabetes items. Face and content validity were ascertained by expert review. One hundred and sixty-eight patients with diabetes mellitus completed the instrument, and reliability was evaluated by a test-re-test procedure 1 week later. Concurrent validity was evaluated by an independent physician interview (n = 33). Measures of glycaemic control (glycated haemoglobin and plasma glucose) were compared with self-reported glycaemic control on a five-point Likert scale in diabetic out-patients (n = 166). RESULTS The questionnaire had adequate face and content validity. There was good to excellent test-re-test reliability for the gastrointestinal and diabetes items (median kappa: 0.63 and 0.79, respectively); concurrent validity was good to excellent (median kappa: 0.47 and 0.65, respectively), except for the items assessing the severity of gastrointestinal symptoms. Both glycated haemoglobin (P < 0.0001) and plasma glucose (P = 0.005) correlated significantly with self-reported glycaemic control. CONCLUSION The Diabetes Bowel Symptom Questionnaire appears to be a useful measure of gastrointestinal symptoms and glycaemic control in diabetes mellitus, and should have applicability in epidemiological and clinical studies.
