Tinkering, Tailoring, and Transforming: Retention of Scientific Excellence of Women Researchers through WiSER mentoring
Women are under-represented in academic grades in Higher Education, but more so in science, engineering and technology (SET) disciplines. This under-representation of women undermines the potential gains the community of science can attain by utilising the skills, talents and knowledge of all those who are trained to work in SET. The European Union statistics show that women are equally represented at undergraduate stage but become progressively more under-represented in the more senior academic positions. This article presents a case study of a mentoring programme in the Centre for Women in Science and Engineering Research (WiSER) at Trinity College Dublin. Its aim is the recruiting, retaining, returning and advancing women in academic science, engineering and technology. WiSER seeks to develop sustainable practices to ensure that women can compete in research in an equitable manner with male colleagues using their scientific expertise, knowledge and potential. The outcomes of the programme are reported for mentors, mentees and Trinity College and retention data are given for the women a year after the programme ended
Structural and Functional Alterations in The Zona Fasciculata of The Rat Adrenal Cortex in Obstructive Jaundice
This study investigated the effect of experimentally-induced cholestasis in the rat on the structure and
function of the zona fasciculata, the glucocorticoid secretory region of the adrenal cortex. Wistar-Furth
rats (200-250g) were assigned to three groups: bile duct ligated (BDL), Sham operated (Sham) and
unmodified normal control (NC). On day 14, serum bilirubin and liver histology were performed to
confirm cholestasis in BDL animals together with basal 24 hour 17-hydroxycorti-costeroid excretion,
adrenal histology and zona fasciculata ultrastructure in all experimental groups. Following this
laparotomy, structural and functional studies were repeated on day 15 to evaluate the response of the gland
to surgically induced stress. Basal 24 hr. 17-hydroxycorticoid steroid excretion was elevated in BDL animals
(26.9 ±3.2 μ g/24 hr) with respect to Sham (10.4 ± 2.3) and NC groups (13.5 ± 3.2) (p <0.05). Adrenal
histology and ultrastructural studies demonstrated excessive accumulation of vesicles laden with
glucocorticoid biogenic precursors. Following surgical stress 24 hr 17 OH corticosteroid excretion increased
in all groups: BDL (31.0 ± 3.0 μg/24 hr) vs Sham (15.6 ± 1.8) and NC (14.5 ± 2.4) Moderate alterations
in zona fasciculata architecture were seen following surgery in all groups. Cholestasis induces overactivity
of the zona fasciculata of the adrenal cortex, and may modify the normal metabolic responses to surgical
and other stresses

Total parenteral nutrition associated cholestasis: A predisposing factor for sepsis in surgical neonates?
Of 496 neonates and infants less than 1 year of age admitted to the paediatric surgical intensive care unit (PSICU) over a 5 year period (1983-1987), 94 required total parenteral nutrition (TPN) for more than 14 consecutive days, generally due to congenital anomalies of the digestive tract. Cholestasis occurred in 15 of them and 12 of these patients developed sepsis. In contrast, of the 79 patients on TPN that remained free from cholestasis, only 23 developed sepsis. The mortality rate for the TPNAC-group was substantially higher than for the group without TPNAC. It is suggested that development of TPNAC might lead to impairment of non-specific cellular immunity in neonates
Virtual reality in specialist palliative care:a feasibility study to enable clinical practice adoption
Background The use of Virtual Reality (VR) is increasing in palliative care. However, despite increasing interest in VR there is little evidence of how this technology can be implemented into practice. Aims This paper aims to: (1) explore the feasibility of implementing VR therapy, for patients and caregivers, in a hospital specialist inpatient palliative care unit and a hospice, and (2) to identify questions for organisations, to support VR adoption in palliative care. Methods The Samsung Gear VR system was used in a hospital specialist palliative inpatient unit and a hospice. Patients and caregivers received VR distraction therapy and provided feedback of their experience. Staff completed a feedback questionnaire to explore their opinion of the usefulness of VR in palliative care. A public engagement event was conducted, to identify questions to support implementation of VR in palliative care settings. Results Fifteen individuals (12 (80%) patients and 3 (20%) caregivers) participated. All had a positive experience. No adverse effects were reported. Ten items were identified for organisations to consider ahead of adoption of VR in palliative care. These were questions about: the purpose of VR; intended population; supporting evidence; session duration; equipment choice; infection control issues; content choice; setting of VR; person(s) responsible for delivery and the maintenance plan. Conclusions It is feasible to use VR therapy in palliative care; however further evidence about its efficacy and effectiveness is needed. Palliative care practitioners considering VR use should carefully consider several factors, to ensure it can be used safely and effectively
Does administration of non-steroidal anti-inflammatory drug determine morphological changes in adrenal cortex: ultrastructural studies
Rofecoxib (Vioxx© made by Merck Sharp & Dohme, the USA) is a non-steroidal anti-inflammatory drug which belongs to the group of selective inhibitors of cyclooxygenasis-2, i.e., coxibs. Rofecoxib was first registered in the USA, in May 1999. Since then the drug was received by millions of patients. Drugs of this group were expected to exhibit increased therapeutic action. Additionally, there were expectations concerning possibilities of their application, at least as auxiliary drugs, in neoplastic therpy due to intensifying of apoptosis. In connection with the withdrawal of Vioxx© (rofecoxib) from pharmaceutical market, attempts were made to conduct electron-microscopic evaluation of cortical part of the adrenal gland in preparations obtained from animals under influence of the drug. Every morning animals from the experimental group (15 rats) received rofecoxib (suspension in physiological saline)—non-steroidal anti-inflammatory drug (Vioxx©, Merck Sharp and Dohme, the USA), through an intragastric tube in the dose of 1.25 mg during 8 weeks. In the evaluated material, there was found a greater number of secretory vacuoles and large, containing cholesterol and other lipids as well as generated glucocorticoids, lipid drops in cytoplasm containing prominent endoplasmic reticulum. There were also found cells with cytoplasm of smaller density—especially in apical and basal parts of cells. Mitochondria occasionally demonstrated features of delicate swelling. The observed changes, which occurred on cellular level with application of large doses of the drug, result from mobilization of adaptation mechanisms of the organism
Preoperative biliary drainage for periampullary tumors causing obstructive jaundice; DRainage vs. (direct) OPeration (DROP-trial)
BACKGROUND: Surgery in patients with obstructive jaundice caused by a periampullary (pancreas, papilla, distal bile duct) tumor is associated with a higher risk of postoperative complications than in non-jaundiced patients. Preoperative biliary drainage was introduced in an attempt to improve the general condition and thus reduce postoperative morbidity and mortality. Early studies showed a reduction in morbidity. However, more recently the focus has shifted towards the negative effects of drainage, such as an increase of infectious complications. Whether biliary drainage should always be performed in jaundiced patients remains controversial. The randomized controlled multicenter DROP-trial (DRainage vs. Operation) was conceived to compare the outcome of a 'preoperative biliary drainage strategy' (standard strategy) with that of an 'early-surgery' strategy, with respect to the incidence of severe complications (primary-outcome measure), hospital stay, number of invasive diagnostic tests, costs, and quality of life. METHODS/DESIGN: Patients with obstructive jaundice due to a periampullary tumor, eligible for exploration after staging with CT scan, and scheduled to undergo a "curative" resection, will be randomized to either "early surgical treatment" (within one week) or "preoperative biliary drainage" (for 4 weeks) and subsequent surgical treatment (standard treatment). Primary outcome measure is the percentage of severe complications up to 90 days after surgery. The sample size calculation is based on the equivalence design for the primary outcome measure. If equivalence is found, the comparison of the secondary outcomes will be essential in selecting the preferred strategy. Based on a 40% complication rate for early surgical treatment and 48% for preoperative drainage, equivalence is taken to be demonstrated if the percentage of severe complications with early surgical treatment is not more than 10% higher compared to standard treatment: preoperative biliary drainage. Accounting for a 10% dropout, 105 patients are needed in each arm resulting in a study population of 210 (alpha = 0.95, beta = 0.8). DISCUSSION: The DROP-trial is a randomized controlled multicenter trial that will provide evidence whether or not preoperative biliary drainage is to be performed in patients with obstructive jaundice due to a periampullary tumor
