Abstract
Aims Rheumatic disease (RMD) patients treated with long-term glucocorticoids (GC) are at risk of developing tertiary adrenal insufficiency. With this survey we aimed to assess the knowledge of RMD patients taking long-term glucocorticoid therapy regarding risk of adrenal insufficiency and understanding of the "steroid sick day rules". Methods RMD patients taking ≥2.5 mg prednisolone daily for ≥3 months were recruited from the Rheumatology outpatient department in Beaumont Hospital, Dublin. Patient knowledge and previous counselling of steroid sick day rules was determined using an 8-point questionnaire carried out face-to-face or via phone call. Results 51 RMD patients on GC therapy were recruited. 3/51 (5.9%) of patients reported that they had been counselled on the Sick Day Rules. 2/51 (3.9%) carried a steroid emergency card or MedicAlert bracelet. Few patients would increase their steroid dose appropriately in response to infection, vomiting or peri-procedure [14/51 (27.5%); 9/51 (17.7%) and 5/51 (7.2%), respectively]. Conclusion We demonstrate a significant deficit of patient knowledge around the precautions for long-term GC use in rheumatic diseases. We suspect that our results may be generalisable to many other RMD units. We are currently reviewing our procedures around healthcare professional and patient education, issuing of information leaflets, emergency cards or MedicAlert bracelets etc. to at risk patients.

Abstract
BACKGROUND Service models for gastrointestinal endoscopy sedation must be safe, as endoscopy is the most common procedure performed under sedation in many countries. The aim of this prospective cohort study was to determine the patient risk profile, and incidence of and risk factors for significant unplanned events, in adult patients presenting for gastrointestinal endoscopy in a group of university-affiliated hospitals where most sedation is managed by anaesthetists. METHODS Patients aged ≥18 yr presenting for elective and emergency gastrointestinal endoscopy under anaesthetist-managed sedation at nine hospitals affiliated with the University of Melbourne, Australia, were included. Outcomes included significant airway obstruction, hypoxia, hypotension and bradycardia; unplanned tracheal intubation; abandoned procedure; advanced life support; prolonged post-procedure stay; unplanned over-night admission and 30-day mortality. RESULTS 2,132 patients were included. Fifty percent of patients were aged >60 yr, 50% had a BMI >27 kg m -2, 42% were ASA physical status III-V and 17% were emergency patients. The incidence of significant unplanned events was 23.0% (including significant hypotension 11.8%). Significant unplanned intraoperative events were associated with increasing age, BMI <18.5 kg m -2, ASA physical status III-V, colonoscopy and planned tracheal intubation. Thirty-day mortality was 1.2% (0.2% in electives and 6.0% in emergencies) and was associated with ASA physical status IV-V and emergency status. CONCLUSIONS Patients presenting for gastrointestinal endoscopy at a group of public university-affiliated hospitals where most sedation is managed by anaesthetists, had a high risk profile and a substantial incidence of significant unplanned intraoperative events and 30-day mortality.

Abstract
The human embryonic stem cell line RCe013-A (RC-9) was derived under quality assured compliance with UK regulation, European Union Directives and International guidance for tissue procurement, processing and storage according to Good Manufacturing Practice (GMP) standards. The cell line was derived from a failed to fertilise oocyte voluntarily donated as unsuitable and surplus to fertility requirements following informed consent. RCe013-A (RC-9) shows normal pluripotency marker expression and differentiation to the three germ layers in vitro and in vivo. It has a normal 46XY male karyotype and microsatellite PCR identity, HLA and blood group typing data are available.

Abstract
Revascularisation of ischaemic tissue remains an area of substantial unmet clinical need in cardiovascular disease. Strategies to induce therapeutic angiogenesis are therefore attractive. Our recent focus has been on human embryonic stem cell (hESC) strategies since hESC can be maintained in a pluripotent state or differentiated into any desired cell type, including endothelial cells (EC), under defined differentiation culture conditions. We recently published a protocol for non-good manufacturing practice (GMP) feeder- and serum-free hESC-EC-directed monolayer differentiation to vascular EC demonstrating the potential to generate hESC-derived EC in a GMP-compliant manner suitable for use in clinical trials. In this study we modified that laboratory protocol to GMP compliance. EC production was confirmed by flow cytometry, qRT-PCR and production of vascular structures in Matrigel®, yielding approximately 30 % mature VE-cadherin(+)/PECAM-1(+) cells using the GMP-compliant hESC line RC13. In conclusion, we have successfully demonstrated the production of vascular EC under GMP-compliant conditions suitable for clinical evaluation.

Abstract
The development of pulmonary granulomatous lesions during mycobacterial infection is a complex phenomenon, in part caused by responses elicited towards the surface glycolipid trehalose 6,6'-dimycolate (TDM; cord factor). The molecular mechanisms underlying granuloma formation following challenge with TDM are not yet completely understood. The present study defines pathologic differences in acute response to Mycobacterium tuberculosis TDM in C57BL/6 mice and mice lacking the C5a receptor (C5aR-/-). Mice were intravenously injected with TDM prepared in water-in-oil-in-water emulsion and examined for histologic response and changes in proinflammatory cytokines and chemokines in lung tissue. Control C5a receptor-sufficient mice demonstrated a granulomatous response that peaked between days 4 and 7. Increased production of macrophage inflammatory protein-1 alpha (MIP-1alpha), interleukin-1beta (IL-1beta) and CXC chemokine KC (CXCL1) correlated with development of granulomas, along with modest change in tumor necrosis factor-alpha (TNF-alpha). In contrast, the C5aR-/- mice revealed markedly exacerbated inflammatory response. The receptor-deficient mice also demonstrated a lack of coherent granulomatous response, with severe oedema present and instances of lymphocytic cuffing around pulmonary vessels. Lung weight index was increased in the C5aR-/- mice, correlating with increased MIP-1alpha, KC, IL-1beta and TNF-alpha over that identified in the congenic C5aR-sufficient controls. Correlate experiments performed in C5-deficient (B10.D2-H2d H2-T18c Hco/oSnJ) mice revealed similar results, leading to the conclusion that C5 plays a significant role in mediation of chemotactic and activation events that are the basis for maturation of granulomatous responses to TDM.

Abstract
We determined the prognostic role of K-ras mutation in tumor tissue of patients with refractory colon cancer who received Marimastat (BB2516). DNA was extracted from paraffin-stored tumor tissue of 27 patients who previously failed 5-fluorouracil and were treated with BB2516. The presence of K-ras mutation was characterized by Polymerase Chain Reaction using ras- and p53-specific primers. ras and p53 oncoprotein expression was analyzed by an automated biotin-avidin immunoproxidase technique. Seventeen patients had a normal K-ras sequence and 10 patients had a K-ras mutation. Median survival of patients with a normal ras sequence was 330 days from the time of BB2516 treatment compared with 160 days for patients with a K-ras mutation (p = 0.0442, Wilcoxon; 0.0130 Log-Rank). No differences in age, sex, cancer stage, surgical treatment, or chemotherapy treatment were observed. Abnormalities involving ras expression did not affect survival. By comparison, median survival for patients with p53 mutation or p53 overexpression was both 158 days after BB2516 treatment. Patients having both K-ras and p53 mutations had the poorest median survival of 113 days (p = 0.035). There is a suggestion by univariate analysis that the presence of a K-ras mutation may predict survival in patients with progressive colon cancer. Further assessment with larger patient numbers and multivariate analysis is indicated.

Abstract
Functional effects of recombinant human granulocyte colony-stimulating factor (rhG-CSF) and recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) were prospectively measured by harvesting blood samples from 51 oncology patients (21 who were receiving no cytokines, 14 receiving rhGM-CSF, and 16 who were receiving rhG-CSF) just before cytotoxic chemotherapy (baseline) immediately before the last cytokine dose (pre), 2 hours after the last cytokine dose (post), and 48 hours after the pre period (follow-up). Neutrophils and monocytes were separated and functional effects were measured by comparing cell-kill percentages, as determined by a microbial cell-kill assay against Staphylococcus aureus and Candida albicans. Optimal cell concentrations (2 x 10(6) monocytes/ml; 4 x 10(6) neutrophils/ml) and effector-to-cell ratios (1:50) were initially determined with blood samples harvested from 23 healthy volunteers. Results in oncology patients indicated that rhGM-CSF improved monocyte-killing activity against S. aureus at follow-up, compared with controls (p = 0.0094) and compared with monocytes from rhG-CSF-treated patients at the post period (p = 0.014). Cell-killing percentage of the rhGM-CSF-treated patients was also enhanced against C. albicans during the post period, compared with controls (p = 0.011) and rhG-CSF-treated patients (p = 0.067). Neutrophil activity was not altered by either cytokine. In conclusion, monocyte-induced microbial killing was enhanced in oncology patients receiving rhGM-CSF after cytotoxic chemotherapy, compared with patients receiving rhG-CSF or no cytokines. No differences in neutrophil activity were observed between patients receiving either cytokine.

Abstract
This trial was undertaken to determine the prognostic role of K-ras (p21), c-erb B-2 (p185) protein expression, and the presence or nonpresence of a K-ras gene mutation in patients with adenocarcinoma of the lung. This was a retrospective study of 103 patients with adeno- or large-cell carcinoma of the lung who had available paraffin-stored tumor material. The relation of several clinical variables to survival was analyzed. Immunohistochemical techniques were used to determine expression of p21 and p185. Polymerase chain reaction (PCR) and sequencing were used to determine K-ras mutation status. Tumor stage was the only nonmolecular clinical variable predictive of survival (p=0.0001). A combination of K-ras mutation and p 185 expression (p=0.0144), ras mutation and strong p21 expression (p=0.0137), and K-ras mutation and the combined expression of p21 and p185 were predictive of poor survival (p=0.0415) in univariate analysis of all patients. The sole presence of K-ras mutation was predictive of survival. Additionally, when combined with elevated p21 or p185 expression in a subset of patients with 4 or more years of follow-up, negative correlation with survival was observed.

Abstract
OBJECTIVE To determine the prognostic role of a K-ras mutation in tumor tissue of patients with refractory colon cancer who received irinotecan hydrochloride (CPT-11). METHODS DNA was extracted from paraffin-stored tumor tissue of 35 patients with progressive colon cancer failing treatment with 5-fluorouracil who subsequently received CPT-11 (100 mg/m2 i.v. per week x 4 weeks with 2 weeks off per course). The first exon of the K-ras gene was amplified by polymerase chain reaction by using K-ras-specific primers followed by mutant enrichment sequencing. Survival differences of patients with a K-ras mutation were compared with those of patients with a normal K-ras status. RESULTS A total of 21 patients had a normal K-ras sequence and 14 patients had a K-ras mutation [GAT, n = 7; TGT, n = 3; and GCT, AGT, GTT, GAC (codon 13), n = 1 each]. Median survival of patients with a normal ras sequence from time of treatment with CPT-11 was 332 days compared with 169 days for patients with a K-ras mutation (p = 0.0036). No differences in age, sex, cancer stage, surgical treatment, or chemotherapy treatment were observed. CONCLUSION Determination of the presence of a K-ras mutation may predict survival in patients with progressive colon cancer after treatment with 5-fluorouracil who receive CPT-11.

Abstract
BACKGROUND Low vision rehabilitation services should be multidisciplinary and should provide patients with as many options as are necessary to help partially sighted individuals maintain independence and quality of life. METHODS A case report is presented of a 30-year-old insulin-dependent diabetic patient with carpal tunnel syndrome. Team management resulted in referral for occupational therapy evaluation and resulted in long cane modification. RESULTS Modification of a long cane was accomplished using a piece of PVC plastic glued at a right angle to the long cane, thus acting as a handle. Fabric straps with Velcro fasteners made the cane movable with forearm rather than wrist motion and allowed the patient to maintain independent travel. CONCLUSIONS This case presents an example of appropriate referral for an occupational therapy evaluation. Low vision rehabilitation demands an interdisciplinary approach.

Abstract
In this study the ambient temperature in which thirty-three Irish infants, within six weeks of birth, were nursed was documented. The study was conducted from October to March and a total of 1,250 individual room temperatures were recorded with a mean of 19.3 degrees C and a range of 8 degrees C, to 28 degrees C. The highest ambient temperature occurred from 1800 to 2100 hours and the lowest from midnight to 0300 hours. There was no central heating in 60% of the homes in this study. Comparing the various methods of home heating we found that houses with a coal fire and back boiler had the greatest range of temperatures recorded (from 10 degrees C to 23.5 degrees C) and also the lowest mean temperature recorded (17.14 degrees C). There was little relationship found between the ambient temperature and the amount of clothing and bedding used and some infants were heavily clothed despite a high ambient temperature. The purpose of this paper is to provide background data on which to base future studies examining the effects of varying ambient temperatures and amounts of clothing on an infant's physiological homeostasis.

Abstract
A state diabetes commission and university diabetes program in Kentucky jointly studied the social and economic impact of diabetes mellitus and its complications on the Commonwealth. This investigation revealed that diabetes was a more serious public health problem than previously supposed. Active, diagnosed diabetes afflicts 4.4% Kentucky's population. Less severe clinical and "borderline" forms of diabetes affect an additional 2.4%. Diabetes is especially prevalent in Appalachian regions and in rural, Western Kentucky. In contrast, its prevalence in Lexington, the second-largest city, is 2.7%, similar to the current, estimated national prevalence. Diabetes is the leading cause of hospitalization by disease, and costs approximately $98,800,000 to $135,000,000. Previous estimates of these social and economic losses were lower, partly because they failed to account for the impact of diabetic complications. An average of 5.23% of all hospitalized Kentuckians have diabetes. Specific services for diabetes care, including organized patient education programs, social or psychological counseling, and preventive foot care, were offered by less than 8% of accredited Kentucky hospitals. This study demonstrates the disparity between need and available services, particularly preventive services, for diabetes care in the health care system.
