Abstract
Cannabis use is present and persistent in young adults with early psychosis receiving Coordinated Specialty Care (CSC) in the United States. While CSC programs are effective in improving quality of life, helping individuals reach goals, and promoting recovery, cannabis use may limit the extent of these improvements. This study extended upon previous findings to examine trajectories of cannabis use among individuals with early psychosis. The sample consisted of 1325 CSC participants enrolled for more than one year at OnTrackNY and followed up to two years, categorized into three groups: no use, reduced use, and persistent use. Baseline demographic and clinical differences were compared across groups and associations between clinical and psychosocial outcomes at 12 months and 24 months were examined across groups. Of the sample, 40 % remained persistent users over two years while 12.8 % reduced their use. At baseline, persistent users were younger (p = 0.011), more likely to be male (p < 0.001), had lower education levels (p = 0.019), and were more likely to have had past legal issues prior to admission (p < 0.001) than non-users. At 2 years, persistent users had significantly worse symptom scores than non-users (p = 0.0003) and reduced users (p = 0.0004). These findings highlight the presence of persistent cannabis use being common in this population and the need to improve substance use treatment offered to allow more CSC participants to achieve improved outcomes.

Abstract
OBJECTIVES The novel coronavirus 2019 (COVID-19) has spread worldwide threatening human health. To reduce transmission, a 'lockdown' was introduced in Ireland between March and May 2020. The aim of this study is to capture the experiences of consultant psychiatrists during lockdown and their perception of it's impact on mental health services. METHODS A questionnaire designed by the Royal College of Psychiatrists was adapted and circulated to consultant members of the College of Psychiatrists of Ireland following the easing of restrictions. The questionnaire assessed the perceived impact on referral rates, mental health act provision, availability of information technology (IT), consultant well-being and availability of personal protective equipment (PPE). Thematic analysis was employed to analyse free-text sections. RESULTS Response rate was 32% (n = 197/623). Consultants reported an initial decrease/significant decrease in referrals in the first month of lockdown (68%, n = 95/140) followed by an increase/significant increase in the second month for both new (83%, n = 100/137) and previously attending patients (65%, n = 88/136). Social isolation and reduced face-to-face mental health supports were among the main reasons identified. The needs of children and older adults were highlighted. Most consultants (76%, n = 98/129) felt their working day was affected and their well-being reduced (52%, n = 61/119). The majority felt IT equipment availability was inadequate (67%, n = 88/132). Main themes identified from free-text sections were service management, relationship between patients and healthcare service and effects on consultants' lives. CONCLUSIONS The COVID-19 pandemic has placed increased pressure on service provision and consultant wellness. This further supports the longstanding need to increase mental health service investment.

Abstract
Abstract
Aim
To determine usual practice and extent of training received by United Kingdom (UK) vascular surgery trainees in microbiological sampling for toe amputations in diabetic patients.
Method
A prospective online survey was distributed via social media networks and trainee organisations. All vascular surgery trainees in the UK were invited to participate. A total of 29 responses were included in the analysis.
Results
86% of respondents have been trained in toe amputations during registrar training. 66% have not been taught which samples to send for microbiological analysis. 10% receive regular training reviews in toe amputations. There is significant variability in the types of samples sent by trainees for microbiological analysis and the majority of trainees did not know how their samples are processed in the laboratory.
Conclusions
Toe amputations appear to be a neglected aspect of training for UK vascular surgery registrars. Lack of consistency in microbiological sampling techniques may prevent optimum antimicrobial stewardship and therefore increase the risk of further complications including major amputation. Inclusion of diabetic foot sepsis as a critical condition in the new vascular surgery curriculum may help to address this issue. A national consensus needs to be reached on how microbiological samples should be taken and processed in order for trainees to be taught in a consistent manner.

Abstract
Recently, the Chinese hamster ovary (CHO) cell-based clustering assay replaced the in vivo Histamine Sensitisation Test (HIST) in mice in European Pharmacopoeia (Ph. Eur.) general chapter 2.6.33. ‘Residual pertussis toxin’ as the recommended method to test for residual pertussis toxin in acellular pertussis vaccine intermediates. To support the standardised CHO clustering assay, availability of a reference standard is critical. Ph. Eur. pertussis toxin Biological Reference Preparation (BRP) batch 1 was first calibrated in International Units in 2008 for the HIST and subsequently also calibrated for the CHO clustering assay in 2017. However, its stocks were dwindling and needed to be replaced. In an effort to maintain adequate supply, a project (BSP141) was initiated by the European Directorate for the Quality of Medicines & HealthCare (EDQM), under the aegis of the Biological Standardisation Programme, to establish a second pertussis toxin BRP (BRP2). Candidate material was manufactured ad hoc by an acellular pertussis vaccine manufacturer and an optimal formulation for long-term stability was defined. Exhaustive in-process and post-production controls demonstrated that the material was fit for its intended purpose and therefore a collaborative study for calibration and stability assessment of the candidate material was organised, which included 10 laboratories worldwide. As a result of the study, the candidate material was established as Ph. Eur. Pertussis toxin BRP batch 2 with a potency of 130 IU/vial for the CHO clustering assay. Unopened vials must be stored at −20°C. The BRP may be used for up to two weeks after reconstitution if appropriately handled and stored at 2–8°C.

Abstract
UNLABELLED Among older adults who have recently sustained a fracture, there is substantial adoption of mobile technology. Furthermore, health and eHealth literacy level reported by participants supports the development of interactive eHealth interventions toward fostering better patient engagement in skeletal health management. INTRODUCTION Electronic health resources are increasingly used in the self-management of medical conditions. We aimed to identify the current level of technology adoption, health, and eHealth literacy among older adults with a recent fracture, to determine if the use of electronic interventions would be feasible and acceptable in this population. METHODS Adults ≥ 50 years with recent fractures were invited to complete a self-administered survey composed of 21 questions, including an 8-item perceived eHealth literacy scale. RESULTS A total of 401 participants completed the survey (women, 64%; ≥ 65 years, 59%; university education, 32%). Most participants reported no difficulty in reading printed health material (67%) and felt confident in filling out medical forms (65%). Younger age and higher levels of education were associated with higher health literacy. Most respondents (81%) owned at least one mobile device (smartphone, 49%; tablet, 45%). eHEALS scores were similar among men (29, IQR 24-32) and women (29, IQR 25-33), and between younger age group categories (50-64 years, 30; IQR 26-33; and 65-74 years, 29; IQR 25-32), but lower in the oldest age group (≥ 75 years, 24; IQR 21-29; p < 0.05). Compared with the youngest group, those ≥ 75 years had higher odds of an eHEALS < 26 (odds ratio, 4.2; 95% confidence interval 2.0-8.9) after adjusting for sex and education level. CONCLUSION There is significant adoption of mobile technology among older adults. Health and eHealth literacy reported by this study population supports the development of interactive eHealth interventions toward fostering better patient engagement in skeletal health management.

Abstract
Objectives Early bedside post-operative monitoring of infrainguinal bypass surgery is currently based on subjective clinical findings and handheld Doppler signals. Infrared thermal imaging is an objective and reproducible technique that has been proven to be a reliable and accurate method to measure skin temperature. The aim of this prospective study was to assess infrared thermal imaging as a predicting tool of bypass graft outcome in the immediate post-operative period and assess the angiosome concept. Methods This was a prospective cohort study of 25 patients undergoing infrainguinal bypass. Demographic and clinical data were prospectively collected and included gender, age, co-morbidities, pre- and post-operative ankle brachial pressure indices, surgery undertaken and patency of run-off vessels. Infrared thermal imaging was undertaken pre- and post-operatively to assess thermal changes to the feet following revascularisation. Results We found that an increase in temperature from pre- to post-operative was significantly associated with bypass patency. An increase in temperature was found to have a positive predictive value of 75%, a negative predictive value of 100%, a sensitivity of 100% and specificity of 89% for predicting graft patency. Conclusions Infrared thermal imaging can be used to measure temperature related changes of the microcirculation post-operatively and predict bypass outcomes in the immediate post-operative period.

Abstract
Cytotoxic chemotherapy has inherent mutagenic potential and alters the bone marrow microenvironment after therapy. In some cases, this potentiates expansion of an aberrant clone and may lead to a therapy-related myeloid neoplasm if the clone overcomes selective pressure. We present the case of a 43-year-old woman diagnosed with an indolent, therapy-related myeloid neoplasm with an isolated chromosome 6p abnormality following treatment for de novo Acute Myeloid Leukaemia (AML), who manifest a sustained spontaneous cytogenetic remission two years later, possibly due to an ineffectual or non-dominant founding clone. This case reminds us to be mindful of the possibility that clonal haematopoiesis may not always equate to clinically relevant disease, even in the setting of an abnormal clonal karyotype.

Abstract
UNLABELLED The results of a self-administered online survey demonstrate that orthopedic surgeons' management practices for AFF are variable. These data will inform the development of clinical practice guidelines. INTRODUCTION We aimed to determine current AFF treatment practices of orthopedic surgeons to inform clinical practice guideline development. METHODS A self-administered online survey was developed and sequentially posted on the Orthopaedic Trauma Association (OTA) website from July to August 2015 and the Canadian Orthopaedic Association (COA) website from December 2015 to January 2016. Level of confidence in diagnosis and treatment as well as treatment preferences between respondents who self-identified as trauma surgeons vs. non-trauma surgeons were compared. RESULTS A total of 172 completed surveys were obtained (OTA, N = 100, 58%; COA, N = 72, 8%). Seventy-eight percent of respondents had treated ≥1 AFF in the previous 6 months. Seventy-six percent reported feeling extremely or very confident in diagnosing AFF (trauma 84% vs. non-trauma surgeons 70%, p = 0.04), and 63% reported feeling extremely or very confident in treating AFF (trauma 82%, non-trauma surgeons 50%, p < 0.01). Preferred management for complete and symptomatic incomplete AFFs was surgical fixation with a cephalomedullary nail (CMN) by 88 and 79%, respectively, while close follow-up was preferred for asymptomatic incomplete AFFs in 72% of respondents. Trauma surgeons used the CMN more frequently than non-trauma surgeons (90 vs. 76% p = 0.03). In patients with bilateral AFFs, with one side surgically treated, 56% were extremely likely to surgically treat the contralateral side, if symptomatic. Most felt guidelines (81%) and educational resources (73%) would be valuable. CONCLUSIONS Current orthopedic treatment practices for AFFs are variable. The results of this survey will inform the development of practice guidelines and educational resources.

Abstract
OBJECTIVE General practitioners (GPs) are crucial in medical healthcare, but there is currently a shortage of GPs in Sweden and elsewhere. Recruitment of GPs from abroad is essential, but foreign-born physicians face difficulties at work that may be related to turnover intention, i.e. wanting to quit one's job. The study aims to explore the reasons to why foreign-born GPs may intend to quit their job. DESIGN Survey data were used to compare four work-related factors that can be associated with turnover intentions; patient-related stress, threats or violence from patients, control of work pace, and empowering leadership, among native-born and foreign-born GPs. These work-related factors were subsequently examined in relation to turnover intention among the foreign-born GPs by means of linear hierarchical regression analyses. The questionnaire consisted of items from the QPS Nordic and items constructed by the authors. SETTING A primary care setting in a central area of Sweden. SUBJECTS Native-born (n = 208) and foreign-born GPs (n = 73). RESULTS Turnover intention was more common among foreign-born GPs (19.2% compared with 14.9%), as was the experience of threats or violence from patients (22% compared with 3% of the native-born GPs). Threats or violence was also associated with increased turnover intention. Control of work pace and an empowering leadership was associated with reduced turnover intention. PRACTICE IMPLICATIONS The organisations need to recognise that foreign-born GPs may face increased rates of threats and/or violence from patients, which may ultimately cause job turnover and be harmful to the exposed individual.

Abstract
INTRODUCTION Vitamin A and its metabolites (called retinoids) have been thought to play a role in the development of idiopathic intracranial hypertension (IIH). The IIH Treatment Trial (IIHTT) showed the efficacy of acetazolamide (ACZ) in improving visual field function, papilledema grade, quality of life and cerebrospinal fluid (CSF) pressure. We postulated that IIH patients would demonstrate elevated measures of vitamin A metabolites in the serum and CSF. METHODS Comprehensive measures of serum vitamin A and its metabolites were obtained from 96 IIHTT subjects, randomly assigned to treatment with ACZ or placebo, and 25 controls with similar gender, age and body mass index (BMI). These included retinol, retinol binding protein, all-trans retinoic acid (ATRA), alpha- and beta-carotenes, and beta-cryptoxanthin. The IIHTT subjects also had CSF and serum vitamin A and metabolite measurements obtained at study entry and at six months. RESULTS At study entry, of the vitamin A metabolites only serum ATRA was significantly different in IIHTT subjects (median 4.33nM) and controls (median 5.04nM, p=0.02). The BMI of IIHTT subjects showed mild significant negative correlations with serum ATRA, alpha- and beta-carotene, and beta-cryptoxanthin. In contrast, the control subject BMI correlated only with serum ATRA. At six months, the serum retinol, alpha-carotene, beta-carotene, and CSF retinol were increased from baseline in the ACZ treated group, but only increases in alpha-carotene (p=0.02) and CSF ATRA (p=0.04) were significantly greater in the ACZ group compared with the placebo group. No other vitamin A measures were significantly altered over the six months in either treatment group. Weight loss correlated with only with the change in serum beta-carotene (r=-0.44, p=0.006) and the change in CSF retinol (r=-0.61, p=0.02). CONCLUSION Vitamin A toxicity is unlikely a contributory factor in the causation of IIH. Our findings differ from those of prior reports in part because of our use of more accurate quantitative methods and measuring vitamin A metabolites in both serum and CSF. ACZ may alter retinoid metabolism in IIH patients.

Abstract
OBJECTIVE To map the current testing being undertaken following pregnancy loss across the UK and to examine the clinical utility in terms of identifying a cause for the loss and in identifying couples at risk of an unbalanced liveborn child. DESIGN Retrospective audit. SETTING UK, for the year 2014. POPULATION An audit of 6465 referrals for genetic testing of tissue samples following pregnancy loss. METHODS Data were obtained by questionnaire from 15 UK regional genetics laboratories. MAIN OUTCOME MEASURES Data were analysed with respect to gestational age, the presence of identified fetal anomalies, methodologies used, abnormality rates and the presence of a parental balanced rearrangement. RESULTS Of 6465 referrals a genetic cause was identified in 22% of cases (before 12 weeks' gestation, in 47%; at 12-24 weeks, in 14%; after 24 weeks, in 6%). In 0.4% of cases a balanced parental rearrangement was identified where there was a risk of an affected liveborn child in a future pregnancy. Eighty percent of genetic imbalances identified were aneuploidy or triploidy and could be identified by quantitative fluorescence polymerase chain reaction alone. There was significant variation across the UK in acceptance criteria, testing strategies and thus level of resolution of testing. CONCLUSIONS Genetic testing of tissues following pregnancy loss identifies a probable cause of fetal demise in 22% of cases, but it is of low clinical utility in identifying couples at risk of a future unbalanced liveborn child. A comprehensive multidisciplinary review is needed to develop proposals for an affordable and equitable service. TWEETABLE ABSTRACT UK audit of genetic testing of fetal loss shows variation in access to and resolution of analysis.

Abstract
Tropical scleractinian corals are particularly vulnerable to global warming as elevated sea surface temperatures (SSTs) disrupt the delicate balance between the coral host and their algal endosymbionts, leading to symbiont expulsion, mass bleaching and mortality. While satellite sensing of SST has proved a reliable predictor of coral bleaching at the regional scale, there are large deviations in bleaching severity and mortality on the local scale that are poorly understood. Here, we show that internal waves play a major role in explaining local coral bleaching and mortality patterns in the Andaman Sea. Despite a severe region-wide SST anomaly in May 2010, frequent upslope intrusions of cold sub-pycnocline waters due to breaking large-amplitude internal waves (LAIW) mitigated coral bleaching and mortality in shallow waters. In LAIW-sheltered waters, by contrast, bleaching-susceptible species suffered severe bleaching and total mortality. These findings suggest that LAIW benefit coral reefs during thermal stress and provide local refugia for bleaching-susceptible corals. LAIW are ubiquitous in tropical stratified waters and their swash zones may thus be important conservation areas for the maintenance of coral diversity in a warming climate. Taking LAIW into account can significantly improve coral bleaching predictions and provide a valuable tool for coral reef conservation and management.

Abstract
Background Suicidal ideation is more prevalent among physicians, compared to the population in general, but little is known about the factors behind surgeons’ suicidal ideation. A surgeon’s work environment can be competitive and characterised by degrading experiences, which could contribute to burnout, depression and even thoughts of suicide. Being a surgeon has been reported to be predictor for not seeking help when psychological distressed. The aim of the present study was to investigate to what extent surgeons in Italy and Sweden are affected by suicidal ideation, and how suicidal ideation can be associated with psychosocial work conditions. Methods A cross-sectional study of surgeons was performed in Italy (N = 149) and Sweden (N = 272), where having suicidal ideation was the outcome variable. Work-related factors, such as harassment, depression and social support, were also measured. Results Suicidal ideation within the previous twelve months was affirmatively reported by 18% of the Italian surgeons, and by 12% of the Swedish surgeons in the present study. The strongest association with having recent suicidal ideation for both countries was being subjected to degrading experiences/harassment at work by a senior physician. Sickness presenteeism, exhaustion and disengagement were related to recent suicidal ideation among Italian surgeons, while role conflicts and sickness presenteeism were associated with recent suicidal ideation in the Swedish group. For both countries, regular meetings to discuss situations at work were found to be protective. Conclusions A high percentage of surgeons at two university hospitals in Italy and Sweden reported suicidal ideation during the year before the investigation. This reflects a tough workload, including sickness presenteeism, harassment at work, exhaustion/disengagement and role conflicts. Regular meetings to discuss work situations might be protective.

Abstract
AIM To audit clinical practice during transport of very preterm infants (<32 weeks) with acute respiratory distress syndrome (RDS) receiving nasal continuous positive airway pressure (NCPAP). METHODS Retrospective cohort study. RESULTS Twenty-seven infants were receiving NCPAP before transport team's arrival, and 23 were commenced on NCPAP after team's arrival. Six infants (12%) failed NCPAP before transfer, 2 infants (4.5%) failed NCPAP less than 24 hours, and 5 infants (11.3%) failed more than 24 hours - 7 days following admission. None died or developed pneumothorax during, or 7 days after admission. We did not observe NCPAP failure during transfer. There was a statistically significant difference between the NCPAP success and NCPAP failure groups for FiO2 at admission (p < 0.05), and the duration of NCPAP (p < 0.05). CONCLUSION NCPAP is a potentially safe and effective mode of respiratory support for very preterm infants during ground, and air transports.

Abstract
Objective The study evaluated patient informed consent (IC) for the Quad screen and examined differences in IC between test acceptors and test refusers. A multidimensional model of IC was used. Methods Women seeking prenatal care at nine obstetrics clinics in a large Midwestern city completed surveys between February and December 2006. Surveys contained measures for three dimensions of IC: intention, understanding and controlling influence. Results 56.2% of women did not meet criteria for all three of our dimensions of IC and therefore failed to give it. The failure rate was higher among women who choose to screen (72.6%) than women who choose not screen (50%) (p < 0.001). Women who met all criteria for IC were over three times less likley to choose to screen (or = 0.32, CI 0.17–0.62 ( p < 0.01)) than women who did not meet criteria for IC. Conclusion The decision to screen for fetal anomalies is less of a deliberated action than the decision not to screen. Women who lack a fundamental understanding of the purpose and nature of the screen may be operating on the belief that the screen is part of standard care and presents no need to deliberate.

Abstract
The purpose of this paper is to introduce a geographic information system (GIS)-based decision support tool that assists the user to select not only areas where (retrofit) sustainable drainage systems (SuDS) could be implemented within a large catchment (>100 ha), but also to allow discrimination between suitable SuDS techniques based on their likely feasibility and effectiveness. The tool is applied to a case study catchment within London, UK, with the aim of increasing receiving water quality by reducing combined sewer overflow (CSO) spill frequency and volume. The key benefit of the tool presented is to allow rapid assessment of the retrofit SuDS potential of large catchments. It is not intended to replace detailed site investigations, but may help to direct attention to sites that have the greatest potential for retrofit SuDS implementation. Preliminary InfoWorks CS modelling of 'global disconnections' within the case study catchment, e.g. the removal of 50% of the total impervious area, showed that CSO spill volume could be reduced by 55 to 78% during a typical year. Using the disconnection hierarchy developed by the authors, the feasibility of retrofit SuDS deployment within the case study catchment is assessed, and the implications discussed.

Abstract
INTRODUCTION The global increase of chronic renal failure has resulted in a growing number of patients on haemodialysis using arteriovenous fistulas (AVFs). By virtue of their very function, AVFs at times shunt blood away from regions distally, resulting in an ischaemic steal syndrome. Distal revascularisation with interval ligation (DRIL) has been described as a procedure to treat symptomatic ischaemic steal. We present our experience in the management of this complication. PATIENTS AND METHODS Six patients with severe ischaemic steal were treated using a DRIL procedure between May 2004 and June 2007. There were three males and three females, all with elbow brachiocephalic AVFs. Symptoms ranged from severe rest pain to digital gangrene. Published results from international studies of 135 DRIL procedures were also reviewed. RESULTS Vascular access was maintained along with the elimination of ischaemic symptoms in the six patients using an ipsilateral reversed basilic vein graft. Interval ligation of the distal brachial artery was performed at the same time. All patients showed immediate and sustained clinical improvement of symptoms with a demonstrable increase in digital pulse oximetry. CONCLUSIONS DRIL is a beneficial treatment option that has proven successful at alleviating ischemic steal symptoms and preserving vascular access. This avoids placement of central lines, its associated risks, and the need to create an alternative sited fistula.

Abstract
OBJECTIVE To evaluate recurrent or delayed worsening of papilledema and visual function in patients with idiopathic intracranial hypertension (IIH) followed for more than 10 years. METHODS This is an Institutional Review Board approved retrospective chart review of 410 patients with the diagnosis of IIH evaluated at the University of Iowa Hospitals and Clinics from January 1984 to January 1996. Of the 410 patients, 20 patients with IIH who were followed over 10 years at the neuro-ophthalmology clinic met the inclusion criteria. Three neuro-ophthalmologists independently evaluated and graded the visual field examinations and optic disc stereo-photographs for each follow-up visit (median = 15). RESULTS Of the 20 patients, 11 demonstrated a stable course of disease without worsening in papilledema or visual field, and 9 patients worsened after a stable course. Of these 9 patients, 6 patients experienced delayed worsening (range: 28 to 135 months from presentation) and 3 patients had recurrence after resolution of papilledema 12 to 78 months from initial resolution of the IIH. CONCLUSION Idiopathic intracranial hypertension is a chronic condition that may worsen after a period of stability, warranting long-term follow-up.

Abstract
OBJECTIVE To determine the long-term outcome of surgical repair of popliteal artery aneurysms (PAA). METHODS A retrospective review of consecutive patients who underwent surgical PAA repair in two vascular surgery units between 1988 and 2006 was performed. Primary and secondary graft patency, limb salvage and patient survival rates were determined using Kaplan-Meier methods. RESULTS 48 patients underwent repair of 63 PAAs (ligation and bypass=45, interposition grafting=18). The 5-year primary graft patency, secondary graft patency, limb salvage and patient survival rates were 75%, 95%, 98% and 81%, respectively. The 10-year primary graft patency rates were significantly lower for emergency cases (59%) compared with elective cases (66%) (p=0.0023). Thirteen patients (16 PAAs) required a total of 20 late re-interventions. Duplex ultrasound was available in 33 of 45 PAAs treated by ligation and bypass. Five (15%) PAAs demonstrated perfusion of the aneurysm sac at median (range) follow up of 75 (1-246) months after primary repair and two of these required emergency re-operation. CONCLUSIONS These data demonstrate that surgical PAA repair is associated with excellent long-term durability and provide an important benchmark with which to compare results of endovascular PAA repair. Patients treated using the ligation and bypass technique should be enrolled in an aneurysm sac surveillance program.

Abstract
The reference sequence for each human chromosome provides the framework for understanding genome function, variation and evolution. Here we report the finished sequence and biological annotation of human chromosome 1. Chromosome 1 is gene-dense, with 3,141 genes and 991 pseudogenes, and many coding sequences overlap. Rearrangements and mutations of chromosome 1 are prevalent in cancer and many other diseases. Patterns of sequence variation reveal signals of recent selection in specific genes that may contribute to human fitness, and also in regions where no function is evident. Fine-scale recombination occurs in hotspots of varying intensity along the sequence, and is enriched near genes. These and other studies of human biology and disease encoded within chromosome 1 are made possible with the highly accurate annotated sequence, as part of the completed set of chromosome sequences that comprise the reference human genome.

Abstract
Although garter snakes at communal overwintering dens on the Canadian prairies have attracted considerable behavioural ecology research, previous studies have relied upon sampling of active animals to describe broad patterns of distribution and abundance of snakes within the den population. We conducted a mark–recapture study to directly quantify temporal and spatial variation in the phenotypic traits (sex, size, body condition) of snakes at the den itself, and those dispersing through woodland 50 m away. Captures of 909 snakes on the days they emerged, and 6653 snakes as they dispersed, revealed massive spatiotemporal heterogeneity in phenotypic traits among samples. Day-to-day variation in weather conditions affected numbers and sex ratios of emerging and dispersing snakes; for example, small females dispersed in greater numbers after unusually cold nights, when harassment by courting males was reduced. Most snakes stayed at the den only briefly (<5 days) prior to dispersal, so that sampling at the den itself (the only evidence available from most previous studies) underestimates the number of animals in the population, as well as the proportions of females, of small adult males and of juvenile animals. Overall, the heterogeneous and temporally dynamic distributions of phenotypic traits (such as sex and size) among our samples are predictable on the basis of the central roles of male–male competition and sexual conflict in the mating system of these snakes. Surprisingly, however, many of the snakes that overwinter at this den play no part in den-based breeding aggregations

Abstract
OBJECTIVE Identify the exposure effects of job family, patient contact, and supervisor support on physical and non-physical work related violence. DESIGN Cross sectional study of employees in a Midwest health care organization, utilizing a specially designed mailed questionnaire and employer secondary data. SUBJECTS Respondents included 1751 current and former employees (42% response rate). RESULTS Physical and non-physical violence was experienced by 127 (7.2%) and 536 (30.6%) of the respondents, respectively. Multivariate analyses of physical violence identified increased odds for patient care assistants (odds ratio (OR) 2.5, 95% confidence interval (CI) 1. 1 to 6.1) and decreased odds for clerical workers (OR 0.1, 95% CI 0.03 to 0.5). Adjusted for job family, increased odds of physical violence were identified for moderate (OR 5.9, 95% CI 2.1 to 16.0) and high (OR 7.8, 95% CI 2.9 to 20.8) patient contact. Similar trends were identified for non-physical violence (OR 1.4, 95% CI 1.1 to 2.0 and OR 1.7, 95% CI 1.3 to 2.3). Increased supervisor support decreased the odds of both physical (OR 0.7, 95% CI 0.6 to 0.95) and non-physical violence (OR 0.5, 95% CI 0.4 to 0.6), adjusting for job family and demographic characteristics. CONCLUSIONS Increased odds of physical violence were identified for the job family of nurses, even when adjusted for patient contact. Increased patient contact resulted in increased physical and non-physical violence, independent of job family, while supervisor support resulted in decreased odds of physical and non-physical violence.

Abstract
Chromosome 9 is highly structurally polymorphic. It contains the largest autosomal block of heterochromatin, which is heteromorphic in 6-8% of humans, whereas pericentric inversions occur in more than 1% of the population. The finished euchromatic sequence of chromosome 9 comprises 109,044,351 base pairs and represents >99.6% of the region. Analysis of the sequence reveals many intra- and interchromosomal duplications, including segmental duplications adjacent to both the centromere and the large heterochromatic block. We have annotated 1,149 genes, including genes implicated in male-to-female sex reversal, cancer and neurodegenerative disease, and 426 pseudogenes. The chromosome contains the largest interferon gene cluster in the human genome. There is also a region of exceptionally high gene and G + C content including genes paralogous to those in the major histocompatibility complex. We have also detected recently duplicated genes that exhibit different rates of sequence divergence, presumably reflecting natural selection.

Abstract
The finished sequence of human chromosome 10 comprises a total of 131,666,441 base pairs. It represents 99.4% of the euchromatic DNA and includes one megabase of heterochromatic sequence within the pericentromeric region of the short and long arm of the chromosome. Sequence annotation revealed 1,357 genes, of which 816 are protein coding, and 430 are pseudogenes. We observed widespread occurrence of overlapping coding genes (either strand) and identified 67 antisense transcripts. Our analysis suggests that both inter- and intrachromosomal segmental duplications have impacted on the gene count on chromosome 10. Multispecies comparative analysis indicated that we can readily annotate the protein-coding genes with current resources. We estimate that over 95% of all coding exons were identified in this study. Assessment of single base changes between the human chromosome 10 and chimpanzee sequence revealed nonsense mutations in only 21 coding genes with respect to the human sequence.

Abstract
Chromosome 13 is the largest acrocentric human chromosome. It carries genes involved in cancer including the breast cancer type 2 (BRCA2) and retinoblastoma (RB1) genes, is frequently rearranged in B-cell chronic lymphocytic leukaemia, and contains the DAOA locus associated with bipolar disorder and schizophrenia. We describe completion and analysis of 95.5 megabases (Mb) of sequence from chromosome 13, which contains 633 genes and 296 pseudogenes. We estimate that more than 95.4% of the protein-coding genes of this chromosome have been identified, on the basis of comparison with other vertebrate genome sequences. Additionally, 105 putative non-coding RNA genes were found. Chromosome 13 has one of the lowest gene densities (6.5 genes per Mb) among human chromosomes, and contains a central region of 38 Mb where the gene density drops to only 3.1 genes per Mb.

Abstract
Chromosome 6 is a metacentric chromosome that constitutes about 6% of the human genome. The finished sequence comprises 166,880,988 base pairs, representing the largest chromosome sequenced so far. The entire sequence has been subjected to high-quality manual annotation, resulting in the evidence-supported identification of 1,557 genes and 633 pseudogenes. Here we report that at least 96% of the protein-coding genes have been identified, as assessed by multi-species comparative sequence analysis, and provide evidence for the presence of further, otherwise unsupported exons/genes. Among these are genes directly implicated in cancer, schizophrenia, autoimmunity and many other diseases. Chromosome 6 harbours the largest transfer RNA gene cluster in the genome; we show that this cluster co-localizes with a region of high transcriptional activity. Within the essential immune loci of the major histocompatibility complex, we find HLA-B to be the most polymorphic gene on chromosome 6 and in the human genome.

Abstract
The finished sequence of human chromosome 20 comprises 59,187,298 base pairs (bp) and represents 99.4% of the euchromatic DNA. A single contig of 26 megabases (Mb) spans the entire short arm, and five contigs separated by gaps totalling 320 kb span the long arm of this metacentric chromosome. An additional 234,339 bp of sequence has been determined within the pericentromeric region of the long arm. We annotated 727 genes and 168 pseudogenes in the sequence. About 64% of these genes have a 5' and a 3' untranslated region and a complete open reading frame. Comparative analysis of the sequence of chromosome 20 to whole-genome shotgun-sequence data of two other vertebrates, the mouse Mus musculus and the puffer fish Tetraodon nigroviridis, provides an independent measure of the efficiency of gene annotation, and indicates that this analysis may account for more than 95% of all coding exons and almost all genes.

Abstract
OBJECTIVE To determine whether heart rate variability (HRV) is reduced in Doberman Pinschers with dilated cardiomyopathy. DESIGN Case series. ANIMALS 62 overtly healthy Doberman pinschers. PROCEDURE Heart rate variability was analyzed in time and frequency domains from data obtained during 24-hour ambulatory electrocardiographic Holter recordings in 41 overtly healthy Doberman pinschers with normal echocardiograms and 21 overtly healthy Doberman pinschers with abnormal echocardiograms. RESULTS Heart rate variability usually was greater during night versus day, and 2 dogs with the most severe myocardial failure had reduced HRV. CONCLUSIONS AND CLINICAL RELEVANCE Reduced HRV was detected only in Doberman Pinschers with the most severe myocardial failure. Thus, HRV in less severely affected dogs is not reduced, or the normal sinus arrhythmia of dogs renders HRV relatively insensitive. Analysis of HRV did not provide additional information relative to the severity of left ventricular dysfunction or risk of sudden death from that which could be derived from echocardiography, analysis of Holter recordings, and signal-averaged electrocardiography.

Abstract
OBJECTIVE To determine results of ambulatory electrocardiography in and outcome of overtly healthy Doberman Pinschers with equivocal echocardiographic evidence of dilated cardiomyopathy. DESIGN Case series. ANIMALS 44 overtly healthy (25 male, 19 female) Doberman Pinschers. PROCEDURE 24-hour ambulatory electrocardiographic (Holter) recordings with > 90% scan quality obtained the same day that echocardiography was performed were reviewed. RESULTS Holter recordings from 42 of 44 (95%) dogs contained ventricular premature complexes (VPC). Fifteen of 44 (34%) dogs had > 100 VPC, 9 (20%) had > 500 VPC, and 5 (11%) had > 1,000 VPC. Nonsustained (< 30 seconds) ventricular tachycardia was detected in 4 dogs. Eighteen of 27 (67%) dogs with > 100 VPC, any couplets or triplets of VPC, or ventricular tachycardia developed dilated cardiomyopathy within 1 year, compared with 8 of 17 (47%) dogs with < 100 VPC, no couplets or triplets of VPC, and no ventricular tachycardia. Of the 18 dogs that did not develop dilated cardiomyopathy within 1 year, 11 (61%) did so within 3 years. CONCLUSIONS AND CLINICAL RELEVANCE Results suggest that a high percentage of Doberman Pinschers with equivocal echocardiographic evidence of dilated cardiomyopathy will be found to have VPC during 24-hour ambulatory electrocardiography and that most will develop echocardiographic abnormalities indicative of cardiomyopathy.
