Abstract
Hypoxic ischemic encephalopathy (HIE) is the most frequent cause of acquired infant brain injury. Early, clinically relevant biomarkers are required to allow timely application of therapeutic interventions. We previously reported early alterations in several microRNAs (miRNA) in umbilical cord blood at birth in infants with HIE. However, the exact timing of these alterations is unknown. Here, we report serial changes in six circulating, cross-species/bridging biomarkers in a clinically relevant porcine model of neonatal HIE with functional analysis. Six miRNAs—miR-374a, miR-181b, miR-181a, miR-151a, miR-148a and miR-128—were significantly and rapidly upregulated 1-h post-HI. Changes in miR-374a, miR-181b and miR-181a appeared specific to moderate-severe HI. Histopathological injury and five miRNAs displayed positive correlations and were predictive of MRS Lac/Cr ratios. Bioinformatic analysis identified that components of the bone morphogenic protein (BMP) family may be targets of miR-181a. Inhibition of miR-181a increased neurite length in both SH-SY5Y cells at 1 DIV (days in vitro) and in primary cultures of rat neuronal midbrain at 3 DIV. In agreement, inhibition of miR-181a increased expression of BMPR2 in differentiating SH-SY5Y cells. These miRNAs may therefore act as early biomarkers of HIE, thereby allowing for rapid diagnosis and timely therapeutic intervention and may regulate expression of signalling pathways vital to neuronal survival.

Abstract
OBJECTIVE To examine the impacts of a large-scale simulation-based extracorporeal cardiopulmonary resuscitation (ECPR) training program in an academic children's hospital. METHODS The study followed a quasi-experimental, mixed-method, time series design. Two-hour high-fidelity ECPR simulations were held monthly in the pediatric, cardiac, and neonatal intensive care units. Intensive care unit-specific cases were used in each unit. The learning objectives for all cases were the same. Each simulation included an average of 11 health care professionals, including nurses, physicians, respiratory therapist, and perfusionists. Impacts of training were examined using Kirkpatrick's 4-level model: reactions, learning, behaviors, and results. Participant surveys, semistructured interviews, facilitator observations, applied cognitive task analysis, and hospital code data were used to examine the impacts of training. RESULTS From February 2014 to October 2016, a total of 332 health care professionals participated in 29 ECPR simulations. Participants enjoyed the simulations and reported learning gains. Applied cognitive task analysis revealed 2 specific behaviors, coordination of compressions with surgical cannulation and performing sterile compressions, that were targeted for further training. The rate of adherence to the ECPR activation protocol improved from 83% (48/58) before simulations started to 95% (92/97) after simulations (P = .02). ECPR activation time decreased from 7 minutes (interquartile range, 4-9 minutes) before simulations started to 2 minutes (interquartile range, 1-4 minutes) after simulations (P < .01). CONCLUSIONS Large-scale simulation-based ECPR training was associated with positive reactions, learning gains, behavioral change, improved adherence to the ECPR activation protocols, and faster activation times. Other children's hospital that perform ECPR should consider simulation-based training.

Abstract
Anti-tubercular drug discovery continues to be dominated by whole-cell high-throughput screening campaigns, enabling the rapid discovery of new inhibitory chemical scaffolds. Target-based screening is a popular approach to direct inhibitor discovery with a specified mode of action, eliminating the discovery of anti-tubercular agents against unsuitable targets. Herein, a screening method has been developed using Mycobacterium bovis BCG to identify inhibitors of amino acid biosynthesis. The methodology was initially optimized using the known branched-chain amino acid biosynthetic inhibitors metsulfuron-methyl (MSM) and sulfometuron-methyl (SMM), and subsequently, whole genome sequencing of resistant mutants and the use of over-expressor strains confirming their mode of action. The GlaxoSmithKline compound library of small molecule inhibitors with known activity against Mycobacterium tuberculosis was then used to validate the screen. In this paper, we have shown that media supplementation with amino acids can rescue M bovis BCG from known amino acid synthesis inhibitors, MSM and SMM, in a pathway specific manner. The therapeutic potential of amino acid biosynthesis inhibitors emphasizes the importance of this innovative screen, enabling the discovery of compounds targeting a multitude of related essential biochemical pathways, without limiting drug discovery toward a single target.

Abstract
A 26-year-old man with history of schizophrenia was admitted for neutropaenia. He was started on clozapine 3 months prior to admission. As a result he had weekly monitoring of his blood counts and on day of admission was noted to have an absolute neutrophil count (ANC) of 450 cells/μL. He was admitted for clozapine-induced agranulocytosis. Clozapine was held and the patient was started on granulocyte colony-stimulating factor (G-CSF) filgrastim and received two doses without any signs of ANC recovery. On further review, it was noted that the absolute monocyte count (AMC) was also low and tracked with the trend of ANC. We then theorised that the impact of clozapine was on a haematopoietic precursor (colony-forming unit granulocyte-macrophage, CFU-GM) which gives rise to both monocytic and myeloid lineages. Therefore, sargramostim GM-CSF was started. After two doses, the ANC and AMC started trending up and by the third dose, both counts had fully recovered. He was discharged from the hospital and there are no plans to rechallenge with clozapine. Thus, we demonstrate a case of monocytopenia accompanying clozapine-induced agranulocytosis with successful use of GM-CSF. At least in this case, the target of the clozapine injury appears to be the CFU-GM, explaining the rapid and full response to GM-CSF after lack of response to G-CSF.

Abstract
Purpose: The purpose of this study was to determine the impact of pharmacist monitoring with a clinical decision support system (CDSS) on clinical outcomes related to intensive care unit (ICU) delirium. Methods: This was a single-center, before-and-after study. This study compares patient outcomes of the preintervention group, which is the standard of care of pharmacist rounding, and the intervention group of pharmacy rounding with the CDSS rules. Using a CDSS, specific delirium risk factor rules were created to alert pharmacists to patients who have an increased risk of developing ICU delirium. Patients were included in the study if they were ⩾18 years of age, admitted to the trauma intensive care unit (TICU), and had one of the CDSS rule alerts. The CDSS notified pharmacists in real time to patients in the intervention group that met these criteria to provide timely recommendations in an effort to prevent ICU delirium. Results: Compared with the preintervention group receiving the standard of care (n = 28), the intervention CDSS group (n = 33) had a nonsignificant trend in decreased incidence of delirium (33.3% vs 24.1%, P = .45), ICU length of stay (LOS) (10.11 vs 7.55 days, P = .26), and ventilator duration (7.11 vs 5.03 days, P = .26). The intervention group had a significantly shorter hospital LOS (14.74 vs 9.98 days, P = .04). There was a nonsignificant increase in mortality with the intervention group from nondelirium causes (24.2% vs 7%, P = .07). Conclusion: The utilization of a CDSS by clinical pharmacists to monitor for delirium-specific risk factors led to a significantly shorter hospital LOS. Further studies using this model are warranted to see the impact on the ICU population.

Abstract
We describe a case of a 36-year-old woman presenting with vaginal bleeding and suboptimally rising serum human chorionic gonadotropin levels, who was investigated for a pregnancy of unknown location. Ultrasonography, laparoscopy and dilatation and curettage failed to reveal signs of an intra-uterine or intra-abdominal pregnancy. Following computed tomography imaging, a mediastinal mass was histologically determined to be a gestational choriocarcinoma. Following surgical resection and chemotherapy, the patient recovered and proceeded to have a successful intra-uterine pregnancy. We describe this exceptionally rare case and emphasise the importance of follow-up of hCG levels in pregnancy of unknown location.

Abstract
Progressive and late-onset neurological disorders such as Parkinson's disease and Alzheimer's disease affect up to 50 million people globally-a number postulated to double every 20 years in a continually aging population. While predisposing allelic variants in several genes clearly confer risk, individual age and specific environmental influences are equally important discriminators of disease onset age and progression. However, none of these factors can independently predict disease with significant precision. Therefore, we must actively develop models that accommodate contributions from all factors, potentially resulting in an A × G × E (age-gene-environment) metric that reflects individual cumulative risk and reliably forecasts disease outcomes. This effort can only be enabled by a deep quantitative understanding of the contribution of these factors to neurodegenerative disease, both individually and in combination. This is also an important consideration because neuronal loss typically precedes clinical presentation and disease-modifying therapies are contingent on early diagnosis that is likely to be informed by an accurate estimation of individual risk. Although epidemiological studies continue to make strong advances in these areas with the advent of powerful "omics"-based approaches, systematic phenotypic modeling of AxGxE interactions is currently more feasible in model organisms such as Drosophila melanogaster where all three parameters can be manipulated with manageable experimental burden. Here, we outline the advantages of using fruit flies for investigating these complex interactions and highlight potential approaches that might help synthesize existing information from diverse fields into a cogent description of age-dependent, environmental, and genetic risk factors in the pathophysiology of neurological disorders.

Abstract
Ambulatory Gynaecology allows a 'see-and-treat' approach to managing gynaecological conditions, providing a more streamlined, integrated care pathway than the traditional gynaecology clinic and inpatient care model. This study was designed to assess patient satisfaction and acceptability of Ambulatory Gynaecology services in Mayo University Hospital, Castlebar, Ireland. It also provided for feedback from patients as to how the service might be improved. Eighty questionnaires were appropriately completed. Outcomes revealed positive responses in 84% with respect to their experience before attending the clinic, 93% relating to the Ambulatory Gynaecology clinic environment, 96% for communication within the service, 91% for their experience during the procedure and 88% for aftercare information. This study concludes that an ambulatory approach to managing a range of gynaecology referrals is a highly acceptable approach in an Irish gynaecological population. Valuable feedback was gained from the study, which will allow us to further enhance the service for our patients.
