Abstract
BACKGROUND Patients with cancer can expect to receive numerous invasive vascular access procedures for intravenous therapy and clinical diagnostics. Due to the increased incidence and prevalence of cancer globally there will be significantly more people who require first-line intravenous chemotherapy over the next ten years. METHODS Our objective was to determine the types of evidence that exist for the vascular access device (VAD) type for the delivery of systemic anti-cancer therapy (SACT) in cancer patients. We used JBI scoping review methodology to identify the types of VADs used for SACT and with a specific search strategy included articles from 2012-2022 published in the English language. We identify (i) type of VADs used for SACT delivery (ii) the type of insertion and post-insertion complications (iii) the geographical location and clinical environment (iv) and whether VAD choice impacts on quality of life (QOL). Findings were presented using the PAGER framework. MAIN FINDINGS Our search strategy identified 10,390 titles, of these, 5318 duplicates were removed. The remaining 5072 sources were screened for eligibility, 240 articles met the inclusion criteria. The most common design include retrospective study designs (n = 91) followed by prospective study designs (n = 31). We found 28 interventional studies with 21 registered in a clinical trial registry and identified no core outcome sets papers specific to VAD for SACT. The most prevalent publications were those that featured two or more VAD types (n = 70), followed by tunnelled intravenous VADs (n = 67). Of 38 unique complications identified, the most frequent catheter related complication was catheter related thrombosis (n = 178, 74%), followed by infection (n = 170, 71%). The county where the most publications originated from was China (n = 62) with one randomized controlled multicenter study from a comprehensive cancer centre. Of the thirty three studies that included QOL we found 4 which reported on body image. No QOL measurement tools specific to the process of SACT administration via VAD are available INTERPRETATION: Our findings suggest a systematic review and meta-analysis of VAD use for intravenous SACT can be considered. However, the development of a core outcome set for SACT should be prioritised. Funding for high quality programs of research for VAD in cancer are needed. Comprehensive cancer centres should lead this research agenda.

Abstract
Alzheimer's disease (AD) is a complex genetic disease, and variants identified through genome-wide association studies (GWAS) explain only part of its heritability. Epistasis has been proposed as a major contributor to this 'missing heritability', however, many current methods are limited to only modelling additive effects. We use VariantSpark, a machine learning approach to GWAS, and BitEpi, a tool for epistasis detection, to identify AD associated variants and interactions across two independent cohorts, ADNI and UK Biobank. By incorporating significant epistatic interactions, we captured 10.41% more phenotypic variance than logistic regression (LR). We validate the well-established AD loci, APOE, and identify two novel genome-wide significant AD associated loci in both cohorts, SH3BP4 and SASH1, which are also in significant epistatic interactions with APOE. We show that the SH3BP4 SNP has a modulating effect on the known pathogenic APOE SNP, demonstrating a possible protective mechanism against AD. SASH1 is involved in a triplet interaction with pathogenic APOE SNP and ACOT11, where the SASH1 SNP lowered the pathogenic interaction effect between ACOT11 and APOE. Finally, we demonstrate that VariantSpark detects disease associations with 80% fewer controls than LR, unlocking discoveries in well annotated but smaller cohorts.

Abstract
AIM To assess the utility of magnetic resonance imaging (MRI) in addition to the additive benefit of the conventional imaging techniques, computed tomography (CT) and nuclear medicine (NM) bone scintigraphy, for investigation of biochemical recurrence (BCR) post-prostatectomy where access to prostate specific membrane antigen (PSMA) positron-emission tomography (PET)-CT is challenging. MATERIALS AND METHODS Relevant imaging over a 5-year period was reviewed. Ethical approval was granted by the internal review board. All patients with suspected BCR, defined as a PSA ≥0.2 ng/ml on two separate occasions, underwent a retrospective imaging review. This was performed on PACS archive search database in a single centre using search terms "PSA" and "prostatectomy" in the three imaging methods; MRI, CT, and NM bone scintigraphy. All PSMA PET CT performed were recorded. RESULTS One hundred and eighty-five patients were identified. Patients with an MRI pelvis that demonstrated distant metastases (i.e., pelvic bone metastases or lymph node involvement more cranial to the bifurcation of the common iliac arteries) were more likely to have a positive CT and/or NM bone scintigraphy. The Pearson correlation coefficient between the findings of M1 disease at MRI pelvis and the presence of distant metastases at CT thorax, abdomen, pelvis and NM bone scintigraphy was calculated at 0.81 (p<0.01) and 0.91 (p<0.01) respectively. CONCLUSION An imaging strategy based on risk stratification and technique-specific selection criteria leads to more appropriate use of resources, and in turn, increases the yield of conventional imaging methods. MRI prostate findings can be used to predict the additive value of CT/NM bone scintigraphy allowing a more streamlined approach to their use.

Abstract
Electroconvulsive therapy (ECT) is the most effective treatment for severe depression, yet its mechanism of action is not fully understood. Peripheral blood proteomic analyses may offer insights into the molecular mechanisms of ECT. Patients with a major depressive episode were recruited as part of the EFFECT-Dep trial (enhancing the effectiveness of electroconvulsive therapy in severe depression; ISRCTN23577151) along with healthy controls. As a discovery-phase study, patient plasma pre-/post-ECT (n=30) was analyzed using 2-dimensional difference in gel electrophoresis and mass spectrometry. Identified proteins were selected for confirmation studies using immunodetection methods. Samples from a separate group of patients (pre-/post-ECT; n=57) and matched healthy controls (n=43) were then used to validate confirmed changes. Target protein mRNA levels were also assessed in rat brain and blood following electroconvulsive stimulation (ECS), the animal model of ECT. We found that ECT significantly altered 121 protein spots with 36 proteins identified by mass spectrometry. Confirmation studies identified a post-ECT increase (P<0.01) in the antiangiogenic and neuroprotective mediator pigment epithelium-derived factor (PEDF). Validation work showed an increase (P<0.001) in plasma PEDF in depressed patients compared with the controls that was further increased post-ECT (P=0.03). PEDF levels were not associated with mood scores. Chronic, but not acute, ECS increased PEDF mRNA in rat hippocampus (P=0.02) and dentate gyrus (P=0.03). This study identified alterations in blood levels of PEDF in depressed patients and further alterations following ECT, as well as in an animal model of ECT. These findings implicate PEDF in the biological response to ECT for depression.

Abstract
BACKGROUND The development of colorectal cancer (CRC) is accompanied by extensive epigenetic changes, including frequent regional hypermethylation particularly of gene promoter regions. Specific genes, including SEPT9, VIM1 and TMEFF2 become methylated in a high fraction of cancers and diagnostic assays for detection of cancer-derived methylated DNA sequences in blood and/or fecal samples are being developed. There is considerable potential for the development of new DNA methylation biomarkers or panels to improve the sensitivity and specificity of current cancer detection tests. METHODS Combined epigenomic methods - activation of gene expression in CRC cell lines following DNA demethylating treatment, and two novel methods of genome-wide methylation assessment - were used to identify candidate genes methylated in a high fraction of CRCs. Multiplexed amplicon sequencing of PCR products from bisulfite-treated DNA of matched CRC and non-neoplastic tissue as well as healthy donor peripheral blood was performed using Roche 454 sequencing. Levels of DNA methylation in colorectal tissues and blood were determined by quantitative methylation specific PCR (qMSP). RESULTS Combined analyses identified 42 candidate genes for evaluation as DNA methylation biomarkers. DNA methylation profiles of 24 of these genes were characterised by multiplexed bisulfite-sequencing in ten matched tumor/normal tissue samples; differential methylation in CRC was confirmed for 23 of these genes. qMSP assays were developed for 32 genes, including 15 of the sequenced genes, and used to quantify methylation in tumor, adenoma and non-neoplastic colorectal tissue and from healthy donor peripheral blood. 24 of the 32 genes were methylated in >50% of neoplastic samples, including 11 genes that were methylated in 80% or more CRCs and a similar fraction of adenomas. CONCLUSIONS This study has characterised a panel of 23 genes that show elevated DNA methylation in >50% of CRC tissue relative to non-neoplastic tissue. Six of these genes (SOX21, SLC6A15, NPY, GRASP, ST8SIA1 and ZSCAN18) show very low methylation in non-neoplastic colorectal tissue and are candidate biomarkers for stool-based assays, while 11 genes (BCAT1, COL4A2, DLX5, FGF5, FOXF1, FOXI2, GRASP, IKZF1, IRF4, SDC2 and SOX21) have very low methylation in peripheral blood DNA and are suitable for further evaluation as blood-based diagnostic markers.

Abstract
Although electroconvulsive therapy (ECT) is the most powerful treatment for depression, substantial variability in use has been described in Ireland. The Mental Health Commission collects usage data from approved centres but does not include home addresses or independent sector patients. Therefore, estimates of regional variation cannot be accurate, e.g. 145 (35% of total) independent sector patients were omitted from their 2008 analysis. When public and independent sector patients are combined inter-regional variation for 2008 is more than halved (chi-squared decreased from 83 to 30), with Western region contributing most to variation (chi-squared = 43). Ratio of ECT programmes to depressed admissions correlated negatively with rate for depressed admissions (r = -0.53, p = 0.01), while depressed admission numbers correlated with acute beds per area (r = 0.68, p = 0.001). Regional variation in ECT is less than previously reported; service factors probably account for much of this with smaller centres admitting severely ill patients more likely to require ECT.

174 Background: Diabetes mellitus (DM) is identified as a negative prognostic indicator in hepatocellular carcinoma (HCC), though the basis for this is unknown. Methods: We conducted a retrospective review of 279 advanced and 191 transplanted HCC patients diagnosed between 1998 and 2008. Logistic regression analyses were conducted to assess the effect of clinical DM on clinical outcomes including distant metastasis and vascular invasion. Results: Eighty- four of 191 (44%) transplanted patients had DM at time of transplantation and 97 of 279 (34%) nontransplanted patients had DM at the time of diagnosis. The presence of DM was associated with an older age at time of diagnosis and a higher prevalence of hepatitis C virus (HCV) and nonalcoholic steatohepatitis (NASH). Also 30% (30/97) of diabetics compared to only 9.3% (17/182) of nondiabetics (p<0.0001) among the cohort with advanced disease had distant metastasis at the time of initial diagnosis, and this difference remained significant when adjusting for CLIP stage, age, and etiologic risk factors in a multivariate logistic regression analysis (OR=8.3, p<0.0001). The association of DM with invasive disease was echoed among early stage transplanted HCC patients in whom histologically confirmed macrovascular invasion was higher among patients with DM compared to those without (20.5% vs. 9.5%, p=0.032). The association of DM with increased risk of macrovascular invasion remained significant in a multivariate logistic regression analysis when adjusting for tumor size, number of nodules, age, obesity and etiologic risk factors (OR=3.2, p=0.025). Conclusions: DM was associated with significantly higher incidence of histological macrovascular invasion in a large cohort of HCC patients receiving liver transplantation and a significantly higher rate of distant metastatic disease at diagnosis in a large cohort of HCC patients with advanced disease. No significant financial relationships to disclose.

Abstract
BACKGROUND AND PURPOSE The HydroCoil is an expansile hydrogel coil designed to produce a greater degree of volumetric packing within cerebral aneurysms when compared with bare platinum coils. This increased packing is, in turn, believed to decrease the risk of recurrence within aneurysms and hence the risk of their rupture in the long term. The aim of this work was to assess whether the use of HydroCoils and the proportion of HydroCoil used have any influence on the subsequent occlusion and recurrence rates of treated aneurysms. MATERIALS AND METHODS A retrospective study was performed of 328 patients during 5 years at a single institution. The initial angiographic and follow-up angiographic occlusion rates were recorded as were any procedural complications. The proportion of HydroCoil used was described as the relative amount of HydroCoil length to the total coil length used during an aneurysm treatment, thus forming 4 groups: 0%-19%, 20%-49%, 50%-69%, 70%-100%, and the subgroups with 100%. RESULTS Two hundred seventy patients had angiographic follow-up during an average of 13 months. The overall risk of permanent neurologic deficit and death was 3%. The rate of complete occlusion was 31% immediately postcoiling and 64.8% on follow-up. At the latest follow-up, 25.6% had residual necks and 9.6% had residual aneurysms. There was a statistically significant trend for HydroCoils to produce greater occlusion rates on follow-up when >70% HydroCoil was used (P = .025). The overall rate of recurrence for all aneurysms as a group was 15.5%. The retreatment rate was 6.6%. There has been 1 rebleed in the 328 patients. CONCLUSIONS The overall results following the use of HydroCoils to occlude aneurysms compare well with those in other reported series. HydroCoils do produce a statistically significantly greater rate of occlusion when >70% of total aneurysm coil length is HydroCoil compared with coiling with <20% HydroCoil. There was no significant difference, however, in the recurrence or retreatment rate when comparing these groups.

Abstract
Robust estimation of allele frequencies in pools of DNA has the potential to reduce genotyping costs and/or increase the number of individuals contributing to a study where hundreds of thousands of genetic markers need to be genotyped in very large populations sample sets, such as genome wide association studies. In order to make accurate allele frequency estimations from pooled samples a correction for unequal allele representation must be applied. We have developed the polynomial based probe specific correction (PPC) which is a novel correction algorithm for accurate estimation of allele frequencies in data from high-density microarrays. This algorithm was validated through comparison of allele frequencies from a set of 10 individually genotyped DNA's and frequencies estimated from pools of these 10 DNAs using GeneChip 10K Mapping Xba 131 arrays. Our results demonstrate that when using the PPC to correct for allelic biases the accuracy of the allele frequency estimates increases dramatically.

Abstract
Those beautiful blue eucalyptus leaves in your Valentine's bouquet may be the product of the new cut-foliage industry in County Kerry, Ireland. Initially, commercial plantations were the victims of an insect accidentally imported from Australia, but two years ago a natural enemy was released and has proven to be an effective control agent for the pest.

Abstract
OBJECTIVES To determine the effects of training in swimming and water safety on young preschool-children's ability to recover safely from a simulated episode of falling into a swimming pool. DESIGN Randomized trial of 12 or eight weeks' duration water safety and swimming lessons for children 24 to 42 months old. OUTCOME MEASURES Swimming ability, deck behavior, water recovery, and swimming to side after jumping into pool were measured before, during, and after the training program. RESULTS 109 children completed the study (61 in the 12 week group, 48 in the eight week group). The average age was 34.2 months, 54% were male. Swimming ability, deck behavior, water recovery, and jump and swim skills improved over baseline levels in both groups. By the end of training, the 12 week group improved more than the eight week group only in swimming ability. Improvements in water recovery and jump and swim skills were associated positively with changes in swimming ability. CONCLUSIONS Swimming ability and safety skills of young preschool children can be improved through training. Such programs may offer some protection for children at risk of drowning and there was no indication that this program increased the risk of drowning. However, pool fencing, other barriers around water, and parental supervision still remain the most important prevention strategies to reduce drowning in young children.

Abstract
CD2 (T11; sheep erythrocyte receptor) is the surface component of an alternative, antigen-independent pathway of human T cell activation. The response to certain anti-CD2 antibodies is relatively independent of accessory cell signals and therefore provides a direct measurement of T cell function. The CD2 pathway may be important in the differentiation of thymocytes, on which the expression of CD2 precedes the appearance of the CD3-T cell receptor complex. In view of the impaired T cell regulation of immune responses in patients with systemic lupus erythematosus (SLE), we examined the activation of peripheral blood lymphocytes by anti-CD2 antibodies in 57 SLE patients and 32 normal control subjects. The CD2 pathway response was lower in the SLE patients (P less than 0.0001); 18 of the 57 SLE patients had a lower response than any of the control subjects. The SLE low-responder patients did not differ from the normal-responder patients in terms of disease activity or use of antiinflammatory and immunosuppressive medications. Low responses to anti-CD2 were corrected to normal by the coaddition of a submitogenic amount of phorbol myristate acetate (1 ng/ml). In some low-responder patients, the responses were normalized by the removal of non-T cells. The data indicate that some SLE patients have impaired responses to CD2 pathway activation and that this may reflect intrinsic T cell defects and/or regulatory influences of non-T cells.

Abstract
Severe systemic lupus erythematosus affecting the kidney or central nervous system may lead to organ failure or death despite treatment with high doses of corticosteroids. To evaluate the clinical and immunologic effects of intravenous cyclophosphamide in this setting, we treated nine patients with monthly intravenous infusions of cyclophosphamide for six months. A comparison of characteristics at entry and follow-up revealed improvements (by paired t-test) in creatinine clearance (66 vs. 96 ml per minute, P less than 0.001); 24-hour urinary protein level (4.11 vs. 0.90 g, P less than 0.05), Farr anti-DNA titer (43 vs. 8.5 percent, P less than 0.01); complement components C3 (894 vs. 1150 mg per liter, P less than 0.05), C4 (154 vs. 222 mg per liter, P less than 0.05), and total complement activity (CH50) (88.7 vs. 113.4 IU, P less than 0.05); and Westergren erythrocyte sedimentation rate (60.2 vs. 34.4 mm per hour, P less than 0.0005). Other manifestations of lupus improved markedly in most cases, despite a reduction in the mean daily dose of prednisone, from 45 mg at entry to 17 mg at follow-up (P less than 0.01). The numbers of lymphocytes positive for T3, T4, T8, and B1 declined progressively during treatment. At follow-up, persistent decreases were observed in the T-lymphocyte subsets, whereas the absolute number of B lymphocytes had returned to levels near base line. T-cell proliferative responses at follow-up were not significantly different from entry values, except that the response to mitogenic anti-T11 (CD2) antibodies was decreased (P less than 0.01). Our data indicate that monthly intravenous administration of cyclophosphamide was associated with a substantial amelioration of severe systemic lupus, in conjunction with discrete changes in T-lymphocyte markers and T-cell function. This was a preliminary, uncontrolled study, but the results warrant further investigation of this form of treatment.
