One essential activity that organisations must review as they capitalise on digital technologies' potential is their existing business processes. Put simply, they must examine 'how things are done around here' and, in doing so, identify if there is any way of improving these activities. In this chapter, I seek to offer an account of delivering a module on 'Innovation, Creativity and Critical Thinking' to final year students of a BA Honours Degree in Insurance Practice. This programme, which commenced in 2016,is Ireland's first apprenticeship towards awarding a level 8 honours degree. The three-year, work-based training programme combines digital academic learning with on-the-job learning, allowing students to acquire various skills. This chapter will demonstrate how students can practically apply techniques learnt in their online class to industry, bridging the theory-practice gap by adopting a learning-by-doing approach to business process re-engineering (BPR).
Background: Pediatric posterior fossa ependymoma contributes to morbidity and mortality in children. Following gross total resection and adjuvant radiotherapy, there is a known risk of local recurrence that portends a dismal prognosis. We sought to characterize survival in a molecularly defined cohort with an emphasis on recurrence patterns that influence outcome. Methods: This study was approved by the Ethics Board of the Hospital for Sick Children. We performed a twenty-year single-center retrospective study to identify clinical, demographic and treatment characteristics of patients with pathologically diagnosed posterior fossa ependymoma. Results: There were 60 patients identified that underwent primary resection. Recurrence rate in the cohort was 48% with 29 cases of recurrent ependymoma occurring at a mean time of 24 months after index surgery. No mortalities were observed among patients undergoing primary resection without recurrent disease. Median cohort survival was 12.3 years in the primary cohort and and 6.32 years among patients recurrent ependymoma. Recurrent disease was significantly associated with worse overall survival after multivariate analysis (HR = 0.024). Conclusions: We highlight overall survival and factors influencing mortality in pediatric posterior fossa ependymoma. Recurrent disease confers a worse prognosis. We describe for the first time survival trends following local and distant recurrences managed through multiple resections.
To systematically review evidence from systematic reviews of interventions to improve dietary behaviours and reduce food wastage in secondary school pupils.
Design:
CINAHL, Cochrane Reviews, EMBASE, MEDLINE, PsychINFO and Web of Science were searched for systematic reviews of school-based dietary interventions from 2000 to 2020 published in a peer-reviewed journal in English. Articles were reviewed independently by two authors. AMSTAR-2 was used for quality assessment.
Setting:
Secondary school dietary interventions.
Participants:
Adolescents (aged 11–18).
Results:
In total, thirteen systematic reviews of dietary interventions in secondary schools met the inclusion criteria. A number of key characteristics of interventions that contributed to improvements in food choices in secondary school pupils were identified. These included the combination of education and environmental restructuring, incorporation of computer-based feedback, media or messaging, peer and/or parent involvement, an increase in the availability of healthy foods and the use of behavioural theory as a basis to the intervention. Intervention components that contributed specifically to a reduction in sugar-sweetened beverage intake or an increase in fruit and vegetable consumption, which are particularly relevant to adolescents, could not be determined. Similarly, evidence for interventions that improve nutritional knowledge and attitudes was limited.
Conclusions:
This systematic review of systematic reviews has identified a number of components of dietary interventions that can be explored to improve dietary behaviours in secondary school environments and, if demonstrated to be effective, be considered for inclusion in policies and strategies to improve the school food environment and promote dietary change.
Schools are a potential stressor for adolescents and may contribute to emergency hospital admissions.
Aims
We describe rates of stress-related presentations (SRPs) among school-aged adolescents (11–17 years) during school terms and holidays, and explore differences by age and gender.
Method
Using national administrative hospital data, we defined an SRP as an emergency hospital admission with a primary diagnosis related to pain, psychosomatic symptoms (e.g. fatigue) or mental health problems, or with self-harm indicated in any diagnostic position. We estimated incidence rate ratios for weekly SRPs in term time versus holidays from 2014–2015 to 2017–2018, using negative binomial regression models, stratified by age and gender. We estimated the cumulative incidence of any SRP between 11 and 17 years by analysing prior hospital admission histories of adolescents with an SRP in 2017–2018.
Results
Over the 4-year study period, 305 491 SRPs in 171 013 school-aged adolescents accounted for 31% of emergency admissions for this group. SRPs were predominantly for mental health problems or self-harm (38%), or pain (35%). Weekly admission rates for SRPs were higher in term time than holidays for all ages (age-specific incidence rate ratios were 1.15–1.49 for girls and 1.08–1.60 for boys). Rates were highest for girls aged 14 and 15 years. The estimated cumulative incidence of any SRP between 11 and 17 years was 7.9% for girls and 4.1% for boys.
Conclusions
Hospital admissions for SRPs are common among adolescents, affecting around two girls and one boy in every classroom. Higher rates in term time than holidays suggest that school factors may contribute.
Background: Treatment of refractory status epilepticus (RSE) is often titrated to achieve EEG burst suppression. However, optimal burst suppression characteristics are largely unknown. We used an unsupervised machine learning algorithm to predict RSE outcome based on the quantitative burst suppression ratio (QBSR). Methods: We conducted principal component analysis (PCA) as a linear combination of 22 QBSR features from non-anoxic adult RSE patients at the Winnipeg Health Sciences Centre. We also determined the most predictive components that significantly differed between survivors and non-survivors. Results: Using 135,765 QBSRs from 7 survivors and 10 non-survivors, PCA identified a predominantly non-survivor cluster of 8 patients (75% non-survivors). The first 2 PCA components comprised 75% data variance. The most important first component feature was skewness of QBSR distribution in the right or left hemisphere (0.52 each). The most important second component feature was third QBSR quantile of the left hemisphere (0.49). Only right hemispheric QBSR features significantly differed between groups: QBSR skewness for the first component (Benjamini-Hochberg adjusted p=0.038) and average QBSR for the second component (0.32, Benjamini-Hochberg adjusted p=0.046). Conclusions: Our pilot study shows that RSE patient survival may be impacted by QBSR, with differential hemispheric EEG burst suppression characteristics predicting poor RSE outcome.
Globally, there is a trend towards conserving biodiversity by promoting co-management with multiple stakeholders at landscape scales. Environmental policies emphasize stakeholder engagement in decision-making, yet landscape conservation is typically a bureaucratic–scientific endeavour. Building trusting relationships with stakeholders is key to negotiations that minimize trade-offs and maximize synergies. Incorporating shared stakeholder objectives improves co-management, as they act as incentives for participation and trust development. We explored the degree of alignment between the bottom-up stakeholder objectives and top-down management objectives of a landscape-scale conservation initiative on the West Coast of South Africa. We categorized stakeholders into six affiliations representing governmental, private and community organizations, and using a social-ecological inventory we identified ten shared objectives. Of these objectives, three were shared between all affiliations, namely biodiversity conservation, socioeconomic development and coordination of the landscape approach. The first two aligned with the top-down landscape management objectives and the latter did not. The importance of coordinating landscape approaches in multi-stakeholder landscape-scale initiatives is crucial to long-term success, and we recommend that it be formally included as a landscape management objective. Exploring the alignment between bottom-up and top-down objectives can highlight overlooked functions of co-management and can reduce the transaction costs of sustaining conservation efforts in the long term.
Ius Constitutionale Commune in Latin America (ICCAL) is an academic endeavour that attempts to provide an account of the original Latin American path of transformative constitutionalism, comprising elements from national, transnational and international legal orders, and where the law is placed at the service of the normative trinity of constitutionalism, namely the rule of law, democracy and human rights. In this regard, ICCAL speaks of an Inter-American law that represents a new legal phenomenon, in a region where constitutionalist ideas have allegedly claimed new traction. In this article, I develop two main critiques that can be deemed challenges for an academic project that is still ‘under construction’, and provide an intellectual map of Latin American constitutionalism that could address these critiques and serve as a roadmap for studying potential Latin American contributions to debates around global constitutionalism.
To compare Lithium prescribing practices in a Psychiatry of Old Age (POA) Service in the North-West ofIreland among adults aged 65 years and over with best practice guidelines.
Methods:
Review of the literature informed development of audit standards for Lithium prescribing. These included National Institute for Clinical Excellent (NICE) 2014 guidelines, The British National Formulary(2019) and Maudsley Prescribing Guidelines (2018). Data was collected retrospectively, using an audit-specific data collection tool, from clinical files of POA team caseload, aged 65 years or more and prescribed Lithium over the past year.
Results:
At the time of audit in February 2020, 18 patients were prescribed lithium, 67% female, average age 74.6 years. Of those prescribed Lithium; 50% (n=9) had depression, 44% (n=8) had bipolar affective disorder (BPAD) and 6% (n=1) schizoaffective disorder.
78% (n= 14) of patients met the NICE standard of 3-monthly lithium level. Lithium levels were checkedon average 4.5 times in past year, average lithium level was 0.61mmol/L across the group and 39% (n=7) had lithium level within recommended therapeutic range (0.6-0.8mmol/L).
83% of patients (n=15) met the NICE standards of 3 monthly renal tests. Taking into consideration mostrecent blood test results, 100% (n=18) had abnormal renal function.
Half (n=9) were initiated on lithium by POA service and of these, 56% (n=5) had documented renal impairment prior to initiation. Of patients on long term lithium at time of referral (n=9), almost half (n=4) had a documented history of lithium toxicity.
Conclusions:
The results of this audit highlight room for improvement in lithium monitoring of older adults attending POA service. Furthermore, all patients prescribed lithium had impaired renal function. This is an important finding given the associations between those admitted to hospital with COVID-19 and co- morbid kidney disease and increased risk of inpatient death.
Our findings highlight the need for three monthly renal function monitoring in elderly prescribed lithiumgiven the additive adverse effects of increasing age and lithium on the kidney. Close working with specialised renal services to provide timely advice on renal management for those with renal impairment prescribed lithium is important to minimise adverse patient outcomes.
Maternal thyroid hormones facilitate optimal foetal neurodevelopment; however, the exact role of the thyroid hormones on specific cognitive outcomes is unknown. The present study aimed to investigate associations between maternal thyroid function and neurodevelopmental outcomes in the Seychelles Child Development Study (SCDS) Nutrition 2 cohort (n 1328). Maternal free thyroid hormones (fT3, fT4 and fTSH) were assessed at 28 weeks’ gestation with a range of child cognitive outcomes analysed at 20 months. Dietary iodine intake was analysed for a subset of women through a Food Frequency Questionnaire. Linear regression analysis was used to test associations between serum concentrations of maternal thyroid hormones and child neurodevelopment outcomes. Thyroid hormones were analysed as continuous data and categorised as quintiles. 95% of mothers had optimal thyroid function based on fTSH concentrations. Overall, the present study shows that maternal thyroid function is not associated with neurodevelopmental outcomes in this high fish-eating population. However, a positive association, using quintiles for fT3, was reported for the Mental Developmental Index, between Q3 v. Q4 (β 0⋅073; P 0⋅043) and for Q3 v. Q5 (β value 0⋅086; P 0⋅018). To conclude, mothers in our cohort, who largely have optimal thyroid function and iodine intakes, appear able to regulate thyroid function throughout pregnancy to meet neurodevelopmental needs. However, it is possible that minor imbalances of fT3, as indicated from our secondary analysis, may impact offspring neurodevelopment. Further investigation of the relationship between maternal thyroid function and infant neurodevelopment is warranted, particularly in populations with different dietary patterns and thereby iodine intakes.
In 2018, the National Centre for Pharmacoeconomics (NCPE) was commissioned to conduct a health technology assessment (HTA) of one of the first commercially available chimeric antigen receptor (CAR) T-cell therapies, tisagenlecleucel. CAR T-cells are a major advance in personalized cancer treatment, demonstrating promising outcomes in relapsed/refractory pediatric acute lymphoblastic leukemia (pALL). However, the results are based on short-term follow up, limiting their value in predicting long-term survival and leading to uncertainty about the most appropriate survival modeling method to employ. This study aimed to address these limitations by means of expert elicitation.
Methods
An expert elicitation method, the histogram technique, was employed. A predefined discrete numerical scale was presented in Microsoft Excel® and the expert was asked to place twenty crosses on a frequency chart. These crosses represented the expert's beliefs about the distribution of particular quantities. Each cross represented five percent of the probabilistic distribution. Individual distributions were then aggregated across experts using linear pooling.
Results
A total of seventeen experts were invited to take part; eight agreed to participate and five completed the exercise. Three experts did not consider tisagenlecleucel to be a “curative” therapy because patients had a higher risk of death, compared with the age- and sex-matched general population. The aggregated distributions indicated the five-year overall survival rate to be thirty-three percent (95% CI 8.65–56.88) in patients who do not receive a subsequent stem cell transplant and twenty percent (95% CI 2.38 -52.04) in those who do.
Conclusions
The results of this study will be used to calibrate CD19 CAR T-cell therapy survival estimates presented in HTA submissions to the NCPE to ensure more robust assessments. They will also be used to inform the construction of a de novo cost-utility model for examining the cost effectiveness of CD19 CAR T-cell therapies for relapsed/refractory pALL in the Irish healthcare setting.
We have recently been funded by the UK Prevention Research Partnership (UKPRP) to develop a UK school food network. The overarching aim is to build a community working towards a more health-promoting food and nutrition system in UK schools (primary and secondary). Here we describe the current status of school food research, including a review of the literature supporting the health-promoting schools approach and outline the opportunities for intervention and innovation establishment of the network present. Key potential school food research themes are described, and their prioritisation within the network, as well as network activities that have been planned, with the ultimate ambition of reducing socio-economic diet-related inequalities, and, consequently, non-communicable disease risk.
In response to the COVID-19 pandemic, there has been a shift globally from face-to-face consultations to remote consultations. In our department, remote consultations have taken in the form of telephone consultations. In this paper, we set out to study a group of Irish psychiatrists’ experience of these consultations.
Methods
We identified recurrent themes in the existing literature on doctors’ experience of telephone consultations with a view to determining the applicability of these themes to a group of Irish psychiatrists. A questionnaire was developed based on themes in the literature. This was sent to all psychiatrists working in a busy psychiatric service in Dublin.
Results
The questionnaire response rate was 72% (n = 26/35). Diagnostic challenges, the effect of phone consultation on the therapeutic alliance, challenges associated with the use of technology and ethical concerns were identified as issues. Flexibility in the working day and convenience were identified as possible benefits to telephone consultations.
Conclusions
The group that participated in this research study identified a number of challenges to carrying out successful phone consultations. This study highlights the need at our clinical site for interventions to address the issues identified by staff. The findings also highlight the requirement for larger studies with stronger methodologies to determine the generalisability of our results.
To identify alterations in neural networks for visual motion perception and pursuit tracking and their interrelationship in schizophrenia, and secondarily to evaluate their comparability to findings in psychotic bipolar disorder.
Methods
Untreated first-episode patients with schizophrenia (N=24) and psychotic bipolar disorder (N=13), and 20 matched healthy participants performed a passive visual motion processing task and a pursuit eye tracking task, which patients have been shown to perform as well as healthy subjects, during functional neuroimaging. Available subjects were retested after four weeks, during which both patient groups received second generation antipsychotics.
Results
During the motion processing task, neither patient group showed reduced activation in V5, but activations in its projection fields in posterior parietal cortex were reduced in both groups. Pursuit related neural activation in both patients groups was not reduced in sensorimotor systems, but was enhanced in anterior intraparietal sulcus and insula. In schizophrenia, activation was also enhanced in dorsolateral prefrontal cortex and dorsomedial thalamus. Greater V5 activation during passive motion processing predicted greater activation in posterior parietal cortex during pursuit in healthy individuals but not in patients. The only significant change at follow-up was decreased anterior cingulate activation during pursuit in schizophrenia.
Conclusions
Reduced transfer of visual motion information to parietal association cortex may compromise information about target speed and tracking error needed for sensorimotor transformations during pursuit tracking in psychotic disorders. Enhanced activation of a prefrontal-thalamo-parietal network during pursuit tracking in schizophrenia may represent compensation for this deficit.
The aim of the study was to assess the experiences of discrimination as reported by people with mental health problems and to explore the impact of hospitalisation.
Methods
306 people with mental health problems provided sociodemographic data and data on discrimination using the discrimination and stigma scale version 12 (DISC-12) with the domains negative experienced discrimination, anticipated discrimination, overcoming stigma and discrimination, and positive experienced discrimination. Logistic regression analysis was used to test the impact of hospitalisation on discrimination, controlled for age, gender, education, employment, diagnosis and having been prescribed medication.
Results
Hospitalisation had a major impact on negative discrimination: People were more likely to be treated unfairly in making or keeping friends, in marriage or divorce, by people in their neighbourhood, in social life, by mental health staff and in terms of privacy, if they had been hospitalised. They were also more likely to be avoided or shunned by people who knew about the mental health problem. People with a history of hospitalisation also reported more anticipated discrimination: They had stopped themselves more often from having a close personal relationship and concealed their mental health problem from others more often than those without a history of hospitalisation. However, people who had been hospitalised also experienced more positive discrimination in terms of being treated more positively in getting welfare benefits or disability pensions and in housing.
Conclusion
Findings suggest that treatment in hospital contributed to a higher extent to experienced discrimination than treatment in the community.
