      Foran, AT; Nason, GJ; Rohan, P; Keane, GM; Connolly, S; Hegarty, N; Galvin, D; O’Malley, KJ (Irish Medical Journal, 2018-04)
      Suprapubic catheter insertion and exchange is a common urological procedure, but it is not without risks and complications. While bowel perforation is a recognised complication at suprapubic catheter insertion, it is not commonly reported at suprapubic catheter exchange. We report our experience of recognition, diagnosis and subsequent successful management of the most important complication related to suprapubic catheters.

      While a great deal of research has been conducted on prodromal risk syndromes in relation to help-seeking individuals who present to the clinic, there is a lack of research on prodromal risk syndromes in the general population. The current study aimed first to establish whether prodromal risk syndromes could be detected in non-help-seeking community-based adolescents and secondly to characterize this group in terms of Axis-1 psychopathology and general functioning. We conducted in-depth clinical interviews with a population sample of 212 school-going adolescents in order to assess for prodromal risk syndromes, Axis-1 psychopathology, and global (social/occupational) functioning. Between 0.9% and 8% of the community sample met criteria for a risk syndrome, depending on varying disability criteria. The risk syndrome group had a higher prevalence of co-occurring nonpsychotic Axis-1 psychiatric disorders (OR = 4.77, 95% CI = 1.81-12.52; P < .01) and poorer global functioning (F = 24.5, df = 1, P < .0001) compared with controls. Individuals in the community who fulfill criteria for prodromal risk syndromes demonstrate strong similarities with clinically presenting risk syndrome patients not just in terms of psychotic symptom criteria but also in terms of co-occurring psychopathology and global functioning.

      The staphylococcal cfr gene mediates resistance to phenicols, lincosamides, oxazolidinones, pleuromutilins, and streptogramin A, a phenotype that has been termed PhLOPS(A). The cfr gene has mainly been associated with coagulase-negative staphylococcal isolates from animals, and only a few cfr-positive methicillin-resistant Staphylococcus aureus (MRSA) isolates have been described so far. This study reports the first description of a cfr-positive MRSA isolate (M05/0060) belonging to the pandemic Panton-Valentine leukocidin (PVL)-positive sequence type 8 MRSA IVa/USA300 (ST8-MRSA-IVa/USA300) clone. The cfr gene was detected in M05/0060 using a DNA microarray which was used to screen PVL-positive MRSA isolates for the presence of virulence genes, typing markers, and antimicrobial resistance genes. Antimicrobial susceptibility testing revealed that M05/0060 exhibited the cfr-associated resistance phenotype. Molecular analysis identified the presence of cfr and a second phenicol resistance gene, fexA, on a novel 45-kb conjugative plasmid, which was designated pSCFS7. Within pSCFS7, a DNA segment consisting of cfr, a truncated copy of insertion sequence IS21-558, and a region with homology to the DNA invertase gene bin3 of transposon Tn552 from Bacillus mycoides was integrated into the transposase gene tnpB of the fexA-carrying transposon Tn558. The emergence of a multidrug-resistant cfr-positive variant of ST8-MRSA-IVa/USA300 is alarming and requires ongoing surveillance. Moreover, the identification of a novel conjugative plasmid carrying the cfr gene indicates the ability of cfr to spread to other MRSA strains.

      A significant number of pancreatic ductal adenocarcinoma present as locally advanced disease. Optimal treatment remains controversial. We sought to analyze the clinical course of locally advanced pancreatic adenocarcinoma (LAPC) in order to identify potential distinct clinical phenotypes.
    • Identification of NR4A2 as a transcriptional activator of IL-8 expression in human inflammatory arthritis.

      Aherne, Carol M; McMorrow, Jason; Kane, David; FitzGerald, Oliver; Mix, Kimberlee S; Murphy, Evelyn P; College of Life Sciences, UCD Veterinary Sciences Centre, University College Dublin, Belfield, Dublin 4, Ireland. (2009-10)
      Expression of the orphan nuclear receptor NR4A2 is controlled by pro-inflammatory mediators, suggesting that NR4A2 may contribute to pathological processes in the inflammatory lesion. This study identifies the chemoattractant protein, interleukin 8 (IL-8/CXCL8), as a molecular target of NR4A2 in human inflammatory arthritis and examines the mechanism through which NR4A2 modulates IL-8 expression. In TNF-alpha-activated human synoviocyte cells, enhanced expression of IL-8 mRNA and protein correspond to temporal changes in NR4A2 transcription and nuclear distribution. Ectopic expression of NR4A2 leads to robust changes in endogenous IL-8 mRNA levels and co-treatment with TNF-alpha results in significant (p<0.001) secretion of IL-8 protein. Transcriptional effects of NR4A2 on the human IL-8 promoter are enhanced in the presence of TNF-alpha, suggesting molecular crosstalk between TNF-alpha signalling and NR4A2. A dominant negative IkappaB kinase antagonizes the combined effects of NR4A2 and TNF-alpha on IL-8 promoter activity. Co-expression of NR4A2 and the p65 subunit of NF-kappaB enhances IL-8 transcription and functional studies indicate that transactivation occurs independently of NR4A2 binding to DNA or heterodimerization with additional nuclear receptors. The IL-8 minimal promoter region is sufficient to support NR4A2 and NF-kappaB/p65 co-operative activity and NR4A2 can interact with NF-kappaB/p65 on a 39bp sequence within this region. In patients treated with methotrexate for active inflammatory arthritis, a reduction in NR4A2 synovial tissue levels correlate significantly (n=10, r=0.73, p=0.002) with changes in IL-8 expression. Collectively, these data delineate an important role for NR4A2 in modulating IL-8 expression and reveal novel transcriptional responses to TNF-alpha in human inflammatory joint disease.
    • Identification of risks associated with the prescribing and dispensing of oral anticancer medicines in Ireland.

      Hammond, Lisa; Marsden, Elaine; O'Hanlon, Niamh; King, Fionnuala; Henman, Martin Charles; Keane, Claire; Pharmacy Department, St. Vincent's University Hospital, Elm Park, Dublin 4, Ireland, l.hammond@st-vincents.ie. (2012-09-09)
      Background Oral anticancer medicines (OAM) facilitate transfer of cancer care into the community, where safeguards developed in hospitals that control their prescribing, dispensing and administration may not exist. Objective To determine if the systems of prescribing and dispensing OAM in Ireland facilitate clinical verification of the prescription, thereby ensuring treatment is tailored and appropriate for the patient. Setting Randomly selected community pharmacies in Ireland and all Irish hospitals with cancer services. Method A questionnaire was sent to a random selection of Irish community pharmacists. A different questionnaire was sent to all Irish hospitals treating cancer patients. One hundred OAM prescriptions were retrospectively reviewed, to assess the information presented and the potential barriers to a community pharmacist performing a clinical verification of the prescription. Main outcome measure Community pharmacist survey: problems experienced when dispensing OAM and risk factors identified with the current system. Hospital pharmacist survey: proportion of hospitals that clinically verify prescriptions for parenteral versus oral anticancer medicines and associated policies. OAM prescription review: proportion of OAM prescriptions that contained sufficient information for a community pharmacist to clinically verify the prescription and safely dispense the medication. Results Sixty-four percent of community pharmacist respondents felt they did not have enough information available to them to safely dispense these prescriptions, and 74 % felt that patients are at risk with the current Irish system of prescribing and dispensing OAM. Irish hospitals do not have systems to ensure that all OAM prescriptions are clinically verified by a pharmacist. Seventeen different agents were prescribed on the prescriptions reviewed. The information provided to the community pharmacist would have allowed them to clinically verify 7 % of the OAM prescriptions. Conclusion Prescriptions for OAM reach the community pharmacist with little chance that they have been clinically verified in the hospital and the medicine reaches the patient with little chance that the community pharmacist has been able to clinically verify it. Healthcare risks are increased when inadequate information about patients and their medicines are available. Appropriate specialist practitioners should be provided nationally to clinically oversee each stage of the OAM use process.
    • Identification of the optimal donor quality scoring system and measure of early renal function in kidney transplantation.

      Moore, Jason; Ramakrishna, Satish; Tan, Kay; Cockwell, Paul; Eardley, Kevin; Little, Mark A; Rylance, Paul; Shivakumar, Kunigal; Suresh, Vijayan; Tomlinson, Kerry; et al. (Transplantation, 2009-02-27)
      The early identification of kidney allografts at risk of later dysfunction has implications for clinical practice. Donor quality scoring systems (preoperative) and measures of early allograft function (first week postoperative) have previously shown practical utility. This study aimed to determine the optimal parameter(s) (preoperative and postoperative) with greatest predictive power for the development of subsequent allograft dysfunction.
    • Identification of those most likely to benefit from a low-glycaemic index dietary intervention in pregnancy.

      Walsh, Jennifer M; Mahony, Rhona M; Canty, Gillian; Foley, Michael E; McAuliffe, Fionnuala M; UCD Obstetrics and Gynaecology, School of Medicine and Medical Science, University College Dublin, National Maternity Hospital,Dublin,Republic of Ireland. (2014-08-28)
      The present study is a secondary analysis of the ROLO study, a randomised control trial of a low-glycaemic index (GI) diet in pregnancy to prevent the recurrence of fetal macrosomia. The objectives of the present study were to identify which women are most likely to respond to a low-GI dietary intervention in pregnancy with respect to three outcome measures: birth weight; maternal glucose intolerance; gestational weight gain (GWG). In early pregnancy, 372 women had their mid-upper arm circumference recorded and BMI calculated. Concentrations of glucose, insulin and leptin were measured in early pregnancy and at 28 weeks. At delivery, infant birth weight was recorded and fetal glucose, C-peptide and leptin concentrations were measured in the cord blood. Women who benefited in terms of infant birth weight were shorter, with a lower education level. Those who maintained weight gain within the GWG guidelines were less overweight in both their first and second pregnancies, with no difference being observed in maternal height. Women who at 28 weeks of gestation developed glucose intolerance, despite the low-GI diet, had a higher BMI and higher glucose concentrations in early pregnancy with more insulin resistance. They also had significantly higher-interval pregnancy weight gain. For each analysis, women who responded to the intervention had lower leptin concentrations in early pregnancy than those who did not. These findings suggest that the maternal metabolic environment in early pregnancy is important in determining later risks of excessive weight gain and metabolic disturbance, whereas birth weight is mediated more by genetic factors. It highlights key areas, which warrant further interrogation before future pregnancy intervention studies, in particular, maternal education level and inter-pregnancy weight gain.
    • Identification of β2-microglobulin as a urinary biomarker for chronic allograft nephropathy using proteomic methods.

      Johnston, Olwyn; Cassidy, Hilary; O'Connell, Séin; O'Riordan, Aisling; Gallagher, William; Maguire, Patricia B; Wynne, Kieran; Cagney, Gerard; Ryan, Michael P; Conlon, Peter J; et al. (2011-08)
      Chronic allograft nephropathy (CAN) remains the leading cause of renal graft loss after the first year following renal transplantation. This study aimed to identify novel urinary proteomic profiles, which could distinguish and predict CAN in susceptible individuals.
    • Identifying coronary artery disease in men with type 2 diabetes: osteoprotegerin, pulse wave velocity, and other biomarkers of cardiovascular risk.

      Davenport, Colin; Ashley, David T; O'Sullivan, Eoin P; Corley, Brian T; Fitzgerald, Patricia; Agha, Amar; Thompson, Christopher J; O'Gorman, Donal J; Smith, Diarmuid; Department of Diabetes and Endocrinology, Royal College of Surgeons in Ireland, Medical School, Beaumont Hospital, Dublin, Ireland. drcdavenport@gmail.com (2012-02-01)
      OBJECTIVES: In patients with type 2 diabetes, high serum levels of osteoprotegerin (OPG) have been associated with a greater risk of cardiovascular events. However, it remains unclear how well OPG performs when compared with traditional biomarkers of cardiovascular risk such as high-sensitivity C-reactive protein (hsCRP). Furthermore, OPG levels are also high in the presence of diabetes-related microvascular disease, and it is unclear whether OPG can distinguish microvascular disease from large-vessel atherosclerosis. The first aim of this study was to compare OPG levels against other biomarkers of cardiovascular risk in the identification of patients with documented multivessel coronary artery disease (CAD). The second aim was to compare OPG levels in patients with microvascular complications (microalbuminuria) against those with established CAD. METHODS: Three groups of male patients with type 2 diabetes were recruited: patients without microvascular complications or large-vessel atherosclerosis (n = 24), patients with microalbuminuria only (n = 23), and patients with microalbuminuria and documented multivessel CAD (n = 25). OPG, hsCRP, interleukin 6, urate, and pulse wave velocity were measured. RESULTS: Serum OPG levels were significantly higher in patients with a combination of microalbuminuria and CAD than in those with microalbuminuria alone. There were no significant differences in any of the other biomarkers between the groups. CONCLUSION: OPG was found to be superior to the other biomarkers studied in identifying patients with documented CAD. The presence of CAD was a greater determinant of serum OPG levels than microalbuminuria in our population. These findings support the use of OPG as a biomarker of cardiovascular risk.

    • Identifying Incomplete Atypical Femoral Fractures With Single-Energy Absorptiometry: Declining Prevalence

      McKenna, Malachi; McKiernan, Fergus; McGowan, Bernie; Silke, Carmel; Bennett, Kathleen; Van Der Kamp, Susan; Ward, Paul; Hurson, Conor; Heffernan, Eric (Journal of Endocrine Society, 2017-03)
      Atypical femur fractures (AFFs) are associated with long-term bisphosphonate (BP) therapy. Early identification of AFF prior to their completion provides an opportunity to intervene, potentially reducing morbidity associated with these fractures. Single-energy X-ray absorptiometry (SE) is an imaging method recently shown to detect incomplete AFF (iAFF) prior to fracture completion.
    • Identifying novel hypoxia-associated markers of chemoresistance in ovarian cancer.

      McEvoy, Lynda M; O'Toole, Sharon A; Spillane, Cathy D; Martin, Cara M; Gallagher, Michael F; Stordal, Britta; Blackshields, Gordon; Sheils, Orla; O'Leary, John J (Springer, 2015)
      Ovarian cancer is associated with poor long-term survival due to late diagnosis and development of chemoresistance. Tumour hypoxia is associated with many features of tumour aggressiveness including increased cellular proliferation, inhibition of apoptosis, increased invasion and metastasis, and chemoresistance, mostly mediated through hypoxia-inducible factor (HIF)-1α. While HIF-1α has been associated with platinum resistance in a variety of cancers, including ovarian, relatively little is known about the importance of the duration of hypoxia. Similarly, the gene pathways activated in ovarian cancer which cause chemoresistance as a result of hypoxia are poorly understood. This study aimed to firstly investigate the effect of hypoxia duration on resistance to cisplatin in an ovarian cancer chemoresistance cell line model and to identify genes whose expression was associated with hypoxia-induced chemoresistance.

    • Idiopathic intracranial hypertension: lumboperitoneal shunts versus ventriculoperitoneal shunts--case series and literature review.

      Abubaker, Khalid; Ali, Zulfiqar; Raza, Kazim; Bolger, Ciaran; Rawluk, Daniel; O'Brien, Donncha; Department of Neurosurgery, Beaumont Hospital, Beaumont, Dublin, Ireland., Khalidnm500@hotmail.com (2012-02-01)
      OBJECTIVES: Idiopathic intracranial hypertension (IIH) is an uncommon but important cause of headache that can lead to visual loss. This study was undertaken to review our experience in the treatment of IIH by neuronavigation-assisted ventriculoperitoneal (VP) shunts with programmable valves as compared to lumboperitoneal (LP) shunts. METHODS: A retrospective chart review was conducted on 25 patients treated for IIH between 2001 and 2009. Age, sex, clinical presentation, methods of treatment and failure rates were recorded. RESULTS: Seventy-two per cent were treated initially with LP shunts. Failure rate was 11% in this group. Neuronavigation-assisted VP shunts were used to treat 28%. In this group, the failure rate was 14%. CONCLUSION: Our experience indicates that both LP shunts and VP shuts are effective in controlling all the clinical manifestations of IIH in the immediate postoperative period. Failure rates are slightly higher for VP shunts (14%) than LP shunts (11%). However, revision rates are higher with LP shunts (60%) than with VP shunts (30%).

    • Idiopathic lymphocytic pleuritis: radiographic and high-resolution CT appearances and changes in response to therapy in two adults.

      O' Donnell, David H; Phelan, Sine; McNicholas, Walter; Gallagher, Charles G; Crotty, Thomas; Dodd, Jonathan D; Department of Radiology, St. Vincent's University Hospital, Elm Park, Dublin 4,, Ireland. (2012-02-01)
      Inflammatory conditions of the pleura characterized by a predominantly lymphocytic infiltrate are described in several disorders. The commonest underlying aetiologies include tuberculous infection, autoimmune disorders (particularly Sjogren's syndrome), and post coronary artery bypass graft surgery. Idiopathic lymphocytic pleuritis (ILP) is a rare form of diffuse pleural inflammation characterized by extensive lymphocytic infiltration for which no cause is found. Radiological descriptions of ILP are limited. We describe the radiographic and high-resolution computed tomography (HRCT) imaging features and response to corticosteroid therapy of ILP in two adults. Both patients presented with bilateral diffuse pleural thickening of >10 mm thickness extending >10 cm craniocaudally with small focal areas of atelectasis. Both cases demonstrated marked improvement in the degree and extent of pleural thickening and rounded atelectasis following corticosteroid therapy. HRCT provided a useful noninvasive method of assessing disease response to therapy.
