Abstract
Usual referral pathways to psychiatric services can miss opportunities for timely intervention in maternal perinatal psychiatric ill health. Psychiatric illness leading to suicide is a significant factor in at least 10% of maternal deaths. Despite Royal College of Psychiatry and National Institute for Health and Clinical Excellence recommendations for specialist provision of perinatal mental health services, this remains sporadic and insufficient. We set out to develop a new integrated antenatal-psychiatric direct referral pathway and present a year of experience using this service model. The psychiatric service was delivered from within the antenatal clinic setting with a direct health-care professional (HCP) led referral pathway between 2003 and 2004. The service comprised one session per week of a senior psychiatric specialist registrar and provided three new patients and two follow-up appointments per week. During this period, a total of 75 referrals to the service were made with 57 individuals attending for an appointment. There was a range of diagnoses among the women who attended, with only 24% meeting eligibility criteria for referral to secondary psychiatric services. The majority diagnosis was depression. More severely ill women were not referred to this clinic by obstetric HCPs. In conclusion, this model for developing and delivering a specialist perinatal psychiatric service using direct links to antenatal medical care was not successful despite requiring minimal funding. Nevertheless, it has been used to inform development of a new perinatal service in keeping with the Royal College of Psychiatrists' recommendations and incorporating enhanced training of HCPs responsible for the referral pathway.

Abstract
The risk factors for and clinical features of bloodstream infection with uncommon Candida spp. (species other than C. albicans, C. glabrata, C. parapsilosis, C. tropicals and C. krusei) are incompletely defined. To identify clinical variables associated with these species that might guide management, 57 cases of candidaemia resulting from uncommon Candida spp. were analysed in comparison with 517 episodes of Candida albicans candidaemia (2001-2004). Infection with uncommon Candida spp. (5.3% of candidaemia cases), as compared with C. albicans candidaemia, was significantly more likely to be outpatient-acquired than inpatient-acquired (15 of 57 vs. 65 of 517 episodes, p 0.01). Prior exposure to fluconazole was uncommon (n=1). Candida dubliniensis was the commonest species (n=22, 39%), followed by Candida guilliermondii (n=11, 19%) and Candida lusitaniae (n=7, 12%).C. dubliniensis candidaemia was independently associated with recent intravenous drug use (p 0.01) and chronic liver disease (p 0.03), and infection with species other than C. dubliniensis was independently associated with age<65 years (p 0.02), male sex (p 0.03) and human immunodeficiency virus infection (p 0.05). Presence of sepsis at diagnosis and crude 30-day mortality rates were similar for C. dubliniensis-related, non-C. dubliniensis-related and C. albicans-related candidaemia. Haematological malignancy was the commonest predisposing factor in C. guilliermondii (n=3, 27%) and C. lusitaniae (n=3, 43%) candidaemia. The 30-day mortality rate of C. lusitaniae candidaemia was higher than the overall death rate for all uncommon Candida spp. (42.9% vs. 25%, p not significant). All isolates were susceptible to amphotericin B, voriconazole, posaconazole, and caspofungin; five strains (9%) had fluconazole MIC values of 16-32 mg/L. Candidaemia due to uncommon Candida spp. is emerging among hospital outpatients; certain clinical variables may assist in recognition of this entity.

Abstract
Owing to the inherent difficulties of studying bluefin tuna, nothing is known of the cardiovascular function of free-swimming fish. Here, we surgically implanted newly designed data loggers into the visceral cavity of juvenile southern bluefin tuna (Thunnus maccoyii) to measure changes in the heart rate (fH) and visceral temperature (TV) during a two-week feeding regime in sea pens at Port Lincoln, Australia. Fish ranged in body mass from 10 to 21 kg, and water temperature remained at 18-19 degrees C. Pre-feeding fH typically ranged from 20 to 50 beats min(-1). Each feeding bout (meal sizes 2-7% of tuna body mass) was characterized by increased levels of activity and fH (up to 130 beats min(-1)), and a decrease in TV from approximately 20 to 18 degrees C as cold sardines were consumed. The feeding bout was promptly followed by a rapid increase in TV, which signified the beginning of the heat increment of feeding (HIF). The time interval between meal consumption and the completion of HIF ranged from 10 to 24 hours and was strongly correlated with ration size. Although fH generally decreased after its peak during the feeding bout, it remained elevated during the digestive period and returned to routine levels on a similar, but slightly earlier, temporal scale to TV. These data imply a large contribution of fH to the increase in circulatory oxygen transport that is required for digestion. Furthermore, these data oppose the contention that maximum fH is exceptional in bluefin tuna compared with other fishes, and so it is likely that enhanced cardiac stroke volume and blood oxygen carrying capacity are the principal factors allowing superior rates of circulatory oxygen transport in tuna.

Abstract
Two empirical models are presented to elucidate the mechanisms driving reductions in the mercury concentration of southern bluefin tuna (SBT) during culture. Model 1 predicts temporal fluctuations in mercury concentration in response to growth dilution. Model 2 predicts the combined effects of growth dilution and linear mercury accumulation. Model 2 was found to be the more accurate model. Over a typical farming period of 136 days, growth dilution resulted in a reduction in mean mercury concentration of SBT edible tissues from 0.51 mg/kg down to 0.33 mg/kg. Extended culture beyond 136 days resulted in an increase in mercury concentration due to the combined effects of mercury accumulation and seasonal lipid depletion. Results indicate that under current industry practice, cultured SBT can be consumed twice as frequently as that of wild caught SBT while maintaining total dietary mercury intake below national recommendations.

Abstract
Talc pleurodesis is the definitive therapy of recurrent pneumothorax and has not been associated with metabolic complications. We report an anephric male infant who developed severe hypercalcemia 6 months following talc pleurodesis for recurrent peritoneal dialysis-related hydrothorax. The etiology of hypercalcemia was related to persistently elevated 1,25-dihydroxyvitamin D(3) (1,25[OH]2D) levels. The source appeared to be the extrarenal production of 1,25(OH)2D from macrophages in a large thoracic talc granuloma. Hypercalcemia was controlled with a combination of a low calcium diet, low calcium dialysis, ketoconazole and hydroxychloroquine, but elevated 1,25(OH)2D levels persisted. At 32 months of age the child underwent renal transplantation with alemtuzumab pre-conditioning. The hypercalcemia resolved immediately, with normalization of serum 1,25(OH)2D levels and without hypercalciuria. This case demonstrates that hypercalcemia is a potential complication of talc pleurodesis from the extrarenal production of 1,25(OH)2D and that alemtuzumab, a monoclonal antibody directed against the CD52 antigen (which is expressed on almost all macrophages), may have a role in the treatment of hypercalcemia associated with granulomatous conditions.

Abstract
Three hundred and sixty two Malus accessions from the Canadian Clonal Genebank of Plant Gene Resources of Canada were cryopreserved as dormant buds at the USDA-ARS National Center for Genetic Resources Preservation in 1996. According to grafting data collected on 165 of these accessions in 1999, 80 percent of the accessions had at least 40 percent viability. A subsample of these accessions was processed for cryopreservation by either adjusting the moisture content of the budwood sections containing dormant buds to 32 or 37 percent moisture (fresh weight basis) or by not drying the budwood sections (46 percent moisture fresh weight basis) prior to cooling. Budwood sections were then slow-cooled at 1 degree C per hour to -3 degree C, held for 24 h at -30 degree C and then rapidly transferred to the vapour phase of liquid nitrogen. Cryopreserved buds from 13 accessions that were dried using the various techniques were warmed and grafted in both 1999 and 2006 to determine viability. Overall, bud viability was high at both storage times. At the 10 year time point, some accessions had higher bud growth when they were desiccated prior to slow-cooling when compared to those that were not.

Abstract
We employed antibody pre-conditioning with alemtuzumab and posttransplant immunosuppression with low-dose tacrolimus monotherapy in 26 consecutive pediatric kidney transplant recipients between January 2004 and December 2005. Mean recipient age was 10.7 +/- 5.8 years, 7.7% were undergoing retransplantation, and 3.8% were sensitized, with a PRA >20%. Mean donor age was 32.8 +/- 9.2 years. Living donors were utilized in 65% of the transplants. Mean cold ischemia time was 27.6 +/- 6.4 h. The mean number of HLA mismatches was 3.3 +/- 1.3. Mean follow-up was 25 +/- 8 months. One and 2 year patient survival was 100% and 96%. One and 2 year graft survival was 96% and 88%. Mean serum creatinine was 1.1 +/- 0.6 mg/dL, and calculated creatinine clearance was 82.3 +/- 29.4 mL/min/1.73 m(2). The incidence of pre-weaning acute rejection was 11.5%; the incidence of delayed graft function was 7.7%. Eighteen (69%) of the children were tapered to spaced tacrolimus monotherapy, 10.5 +/- 2.2 months after transplantation. The incidence of CMV, PTLD and BK virus was 0%; the incidence of posttransplant diabetes was 7.7%. Although more follow-up is clearly needed, antibody pre-conditioning with alemtuzumab and tacrolimus monotherapy may be a safe and effective regimen in pediatric renal transplantation.

Abstract
OBJECTIVES To explore the effect of obstetric emergency training on knowledge. Furthermore, to assess if acquisition of knowledge is influenced by the training setting or teamwork training. DESIGN A prospective randomised controlled trial. SETTING Training was completed in six hospitals in the South West of England, UK and at the Bristol Medical Simulation Centre, UK. POPULATION Midwives and obstetric doctors working for the participating hospitals were eligible for inclusion in the study. A total of 140 participants (22 junior and 23 senior doctors, 47 junior and 48 senior midwives) were studied. METHODS Participants were randomised to one of four obstetric emergency training interventions: (1) 1-day course at local hospital, (2) 1-day course at simulation centre, (3) 2-day course with teamwork training at local hospital and (4) 2-day course with teamwork training at simulation centre. MAIN OUTCOME MEASURES Change in knowledge was assessed by a 185 question Multiple-Choice Questionnaire (MCQ) completed up to 3 weeks before and 3 weeks after the training intervention. RESULTS There was a significant increase in knowledge following training; mean MCQ score increased by 20.6 points (95% CI 18.1-23.1, P < 0.001). Overall, 123/133 (92.5%) participants increased their MCQ score. There was no significant effect on the MCQ score of either the location of training (two-way analysis of variants P = 0.785) or the inclusion of teamwork training (P = 0.965). CONCLUSIONS Practical, multiprofessional, obstetric emergency training increased midwives' and doctors' knowledge of obstetric emergency management. Furthermore, neither the location of training, in a simulation centre or in local hospitals, nor the inclusion of teamwork training made any significant difference to the acquisition of knowledge in obstetric emergencies.
