Abstract
BACKGROUND AND OBJECTIVE Predicting the duration of surgical procedures is an important step in scheduling operating rooms. Many factors have been shown to influence the duration of a procedure, in this research we aim to use medical ontological information to improve the predictions. METHODS This paper presents two methods for incorporating the medical information about a surgical procedure into the prediction of the duration of the procedure. The first method uses the Systematised Nomenclature of Medicine Clinical Terms to relate different procedures to each other. The second uses simple text fragments. The relationships between types of procedures are included in a regression model for the procedure duration. These methods are applied to data from New Zealand healthcare facilities and the accuracy of the estimations of the durations is compared. In addition a simulation of scheduling the procedures in an operating room is performed. RESULTS It is shown that both of the methods provide an improvement in the prediction of procedure durations. When compared to a traditional categorical encoding, the ontological information provides an improvement in the continuous ranked probability scores of the prediction of procedure durations from 18.4 min to 17.1 min, and from 25.3 to 21.3 min for types of procedures that are not performed very often. CONCLUSIONS Different methods for encoding medical ontological information in surgery procedure duration predictions are presented, and show an improvement over traditional models. The improvement in duration prediction is shown to improve the efficiency of scheduling in a simple simulation.

Abstract
Abstract
Background
Sarcopenia, frailty, and malnutrition are known determinants of adverse health outcomes. Adults of advanced age, with functional dependency, socioeconomic disadvantage, or a need for home care, are expected to be at high risk of these conditions yet are likely to be underrepresented in research. We aimed to examine the feasibility and preliminary outcomes of conducting home-based assessments in this group.
Methods
Home-based health assessments were conducted among older adults (n= 31), in receipt of state-funded home care. Assessments included probable sarcopenia [hand-grip strength (HGS), chair rise-test and SARC-F case-finding tool] in line with the European Working Group on Sarcopenia in Older People 2 (EWGSOP2) guidelines, the Mini Nutritional Assessment (MNA), and the Clinical Frailty Scale (CFS).
Results
The study group was of mean age 83.2 ± 8.2 years, 74% female, 23% lived in socioeconomically disadvantaged areas, had comorbidities (n=30, 97%) and low physical activity (71%). We found that almost all met the criteria for probable sarcopenia (94%, 29/31), most were frail or vulnerable by CFA (97%, 30/31), and over a quarter were at risk of malnutrition (26%, n=8). In all participants, it was feasible to assess sarcopenia (by HGS and SARC-F, but not chair rise test), malnutrition (MNA), and frailty (CFS). Notably, in-home assessments required additional time, the adaptation of assessment tools, responsibility to address issues arising, including signposting to health services (36%, n=11), and navigating complex psychosocial environments; the latter was commonly observed in areas of socioeconomic disadvantage.
Conclusion
Assessing sarcopenia, frailty, and malnutrition in community-dwelling dependant older adults in-home was feasible, once potential challenges were considered. Moreover, our findings suggest that most participants were at risk of both sarcopenia and frailty, and over a quarter were at risk of malnutrition. This highlights a need for further research and proactive evidence-based multi-modal community interventions to support ageing in place.

Abstract
Aim We set out to identify the current practice in the anaesthesiology departments of Ireland's public hospitals that deliver paediatric anaesthesia with regard to pre-operative screening for sickle cell disease (SCD) and Sickle cell trait (SCT). Methods The Departments of Anaesthesiology at 14 public HSE-funded hospitals that deliver paediatric anaesthesia were contacted over a three month period in 2020. Any existing policies regarding pre-operative screening of paediatric patients for Sickle cell disease or trait were sought. Comparisons were made between any screening policies in place. Results A response was received from 11 of the 14 hospitals. Three out of 11 of the Anaesthesiology Departments have formal policies in place. The ethnicities identified for pre-operative screening varied across these three hospitals. Conclusion Despite a significant increase in the number of people of African, middle Eastern & Indian descent living in Ireland in recent years, no neonatal screening programme for Sickle cell exists here, and no national policy exists with criteria to guide the practice of pre-operative screening of patients for SCD/SCT (trait). Our survey highlights a lack of standardisation in the approach to pre-operative sickle cell screening of children across Ireland's public hospital system. In view of the increasing multiculturalism in Ireland we recommend a national review of the merits of the introduction of developing a targeted national guideline for pre-operative screening for sickle cell in at-risk children.

Abstract
BACKGROUND STI rates have been reported as reduced during the height of the COVID-19 pandemic. Our study evaluates the number of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections recorded relative to the number of tests performed in 2017-2021, thus accurately depicting trends over time and evaluate the effect of COVID-19 restrictions since these were implemented in March 2020. METHODS Data was extracted from an electronic database of pathology and clinical records used at Gold Coast Sexual Health Service (GCSHS) in Queensland, Australia from January 2017 to October 2021. Poisson regression-based interrupted time series analyses were performed for number of tests performed and test positivity over the study period. The COVID-19 period was defined as starting from March 2020 when public health directives were implemented. RESULTS CT and NG testing dropped significantly in the month after COVID-19 restrictions were brought in, by 30% and 23% respectively. Over the 5year study period, the proportion of positive CT tests has consistently decreased by approximately 0.33% points per year (P≤0.001). The instigation of COVID-19 restrictions had no effect on this trend. The proportion of NG positive tests remained steady prior to COVID-19 (P=0.96) at approximately 3.5%, decreased immediately at the onset of COVID-19 restrictions to approximately 2.5% (P<0.001) and has remained at this level post-COVID restrictions (P=0.54). Testing at GCSHS continued to target gay and bisexual men, accounting for ≥50% of all tests performed. CONCLUSION Our study suggests that there has been a sustained reduction in test positivity of NG infections in the 18months since COVID-19 restrictions were implemented, and that this is not an artifact of reduced testing. It highlights the importance of maintaining health messaging including screening for sexually transmissible infections and maintaining access to services, which may include alternative models of care such as Telehealth, self-testing and collaboration between all sexual health service providers.

Abstract
Abstract
Background
Physical activity programmes have been shown to improve older adults’ functional capacity, independence and quality of life. Research around structured exercise programmes has been completed in different groups of community-dwelling older people, however few studies have focused on the older population receiving formal home care. In a feasibility study, we embedded physical activity within older adults existing home care services through the ‘Care to Move’ (CTM) programme. The aim of this qualitative study is to explore older adults’ experiences of the CTM programme.
Methods
We conducted semi-structured telephone interviews with 13 older adults and one carer. Topics covered included participants overall experiences of the CTM programme, changes to their overall activity and participation, aspects of the programme that they liked or found valuable and issues that they found challenging. Interview transcripts were coded and analysed thematically to capture barriers and facilitators to programme delivery.
Results
Four themes emerged: i) ‘I’m feeling good about it’, ii) ‘safety and security is the name of the game’, iii) ‘we’re a team as it stands’, iv) ‘it’s [COVID] depressing for everybody at the moment’. Older adults identified benefits of CTM participation including improvements in physical and psychological wellbeing. However, frailty and multimorbidity influenced overall engagement. Participants expressed concerns around the logistics of programme delivery and competing healthcare assistant (HCA) interests. The broader role of HCA’s in supporting the CTM programme was highlighted as well as the emotional support that HCAs provided to older adults. HCA continuity was identified as a barrier to ongoing programme engagement. The impact of COVID on older adults physical and mental health negatively impacted programme delivery.
Conclusion
Our findings suggest that embedding the CTM programme within home support services is feasible. Restructuring of services, addressing HCA continuity, and adopting individual approaches to programme delivery may enhance the implementation of services.

Abstract
Abstract
Background
In Ireland, over 53,000 older adults are supported in their community by formal home support, amounting to an estimated 19 million care hours annually. There is a growing need to move beyond care, to more proactive approaches to maintain physical function. In a feasibility study, we delivered the ‘Care to Move’ (CTM) programme through existing home support services. The aim of the present qualitative study was to explore the experience and perceptions of Health Care Assistants (HCAs), who were trained in, and delivered the CTM programme.
Methods
We conducted semi-structured telephone interviews with 22 HCAs involved in the delivery of the programme among older adults [n = 35, mean age 82.8 (7.8) years]. Interview transcripts were coded and analysed thematically to capture barriers and facilitators to programme delivery.
Results
Barriers and facilitators were identified under three main themes i) the programme ii) the care setting, iii) the clients. Overall, there was a positive perception of the programme’s focus on ‘movement prompts and motivators’, the ‘fit’ within home support services, and the training provided. Practical challenges of limited time and the task-orientation nature of home support were reported as recurring barriers for CTM. Many HCAs commented on the value and perceived positive benefits of the programme for their clients. Though negative perceptions of older adult’s motivation or ability to engage with physical activity also emerged. Risk, such as injury or pain, was identified but was not a dominant theme.
Conclusion
Our preliminary findings suggest that embedding physical activity initiatives within home support services could be feasible. Restructuring of services, engaging HCAs, and moving beyond traditional ‘task-oriented' care models to more personalised proactive approaches may facilitate this initiative and support ageing in place.

Abstract
Abstract
Endoleak is a recognised complication after Endovascular Abdominal Aortic Aneurysm Repair (EVAR). In the setting of a rapidly expanding aneurysm – time is of the essence. Perfusion of the renal arteries, superior mesenteric artery (SMA) and coeliac artery must be maintained. To facilitate this a customised fenestrated endograft may be used or a chimney endovascular aortic repair (CHEVAR).
A 78-year-old female initially underwent EVAR in 2016 for a ruptured 6.9cm AAA. She made a good recovery at that time. She was enlisted in a surveillance programme. Her most recent duplex showed an aneurysmal sac of 10cm with associated type 1A endoleak. Given these findings waiting for a fenestrated graft posed an unacceptable delay. She underwent a CHEVAR with bilateral axillary and right femoral access. She had chimney stents deployed in the renal arteries and SMA with aortic cuff extension proximally. Her completion angiogram showed good proximal seal with patent stents. She was unexpectedly unstable post-operatively and had a CT scan which revealed a re-ruptured aneurysm. She was treated in ICU and recovered well. Repeat imaging showed good flow in all 4 grafts with no endoleak.
This case demonstrates the challenges of managing endoleak post EVAR and the importance of robust surveillance and appropriate, timely treatment.

Abstract
The objective of this study was to investigate the economic performance of 2 genetic groups (GG) of Holstein-Friesian dairy cows of divergent Economic Breeding Index (EBI), evaluated within 3 contrasting spring-calving pasture-based feeding treatments (FT). The study was a simulated economic appraisal, using the Moorepark Dairy Systems Model, a stochastic budgetary simulation model integrating biological data obtained from a 4-yr experiment conducted from 2013 to 2016. The 2 divergent GG were (1) high EBI representative of the top 5% nationally (elite) and (2) EBI representative of the national average (NA). The 3 FT were reflective of slight restriction to generous feeding. The elite GG had the lowest replacement rate, and therefore had lower replacement costs and an older and more productive parity structure. The elite GG consistently had higher sales of milk (on average +3% or +18,370 kg of milk) and milk solids (milk fat plus protein yield; +8.7% or +4,520 kg) compared with the NA GG across the 3 FT scenarios. Milk income was consequently greater for elite versus NA (on average +9.5% or +€21,489) cows. Livestock sales were greater (on average +13.2% or +€4,715) for NA compared with elite cows. Baseline net farm profit and net profit/ha at a base milk price of 29.5 cents per liter (3.3% protein and 3.6% fat) were on average €31,156, and €772 greater for elite compared with NA cows across the 3 FT. Greater profitability achieved with elite cows in each of the FT investigated demonstrated the adaptability of high-EBI cows across different levels of feeding intensities in seasonal pasture-based feeding systems. Sensitivity analysis of varying milk price and concentrate cost did not result in a reranking of GG for farm profit. This study clearly demonstrates the power of a suitably constructed genetic-selection index together with a well-considered breeding program to deliver genetics capable of favorable change to farm physical performance and profit over a relatively short duration.

Abstract
Epidermolysis bullosa (EB) is a complex rare condition that affects the skin and many parts of the body. Those born with EB have skin so fragile they are called 'butterfly children', their skin is quite simply as fragile as the wing of a butterfly. In the UK it is estimated that there are more than 5,000 people living with EB and 500,000 worldwide. Little clinical guidance for care existed until DEBRA International started a programme to develop clinical practice guidelines (CPGs). There were no previous guidelines and few published studies on foot care in EB so treatment decisions were largely based on individual opinion and experience. The panel - made up of clinical experts and people living with EB representing Australia, the UK, and the USA - aimed to describe foot problems in people of all ages with EB, and summarise current evidence and management. The authors used a logical podiatric (foot) care literature review focussed on patients with EB. The authors found that the evidence in this area was limited but several interventions (treatments) currently practised by podiatrists show positive outcomes. The study allowed the group to make recommendations on how to treat foot and nail disorders in patients with EB. Furthermore, the authors concluded that further research is needed. This is a summary of the study: Foot care in epidermolysis bullosa: evidence-based guideline.

Abstract
The degree of accuracy in surgery duration estimation directly impacts on the quality of planned surgical lists. Model selection for the prediction of surgery duration requires technical expertise and significant time and effort. The result is often a collection of viable models, the performance of which varies across different strata of the surgical population. This paper proposes a prediction framework to be used after a comprehensive model selection process has been completed for surgery duration prediction. The framework produces a partition of the surgical cases and a "hybrid model" that allocates different predictors from the collection of viable models to different parts of the surgical population. The intention is a flexible prediction process that can reassign models and adapt as surgical processes change. The framework is tested via a simulation study, and its utility is demonstrated by predicting surgery durations for Ear, Nose and Throat surgeries in a New Zealand hospital. The results indicate that the hybrid model is effective, performing better than standard model selection in two of the three simulation studies, and marginally worse when the selected model was the true underlying process.

Abstract
The objective of the current study was to examine phenotypic fertility performance and survival, and to gain insight into underlying factors that may contribute to greater fertility performance in 2 divergent genetic groups (GG) of Holstein-Friesian, selected using the Irish Economic Breeding Index (EBI). The GG were evaluated across 3 spring calving pasture-based feeding treatments (FT) over 4 yr. The 2 divergent GG were (1) high EBI; representative of the top 5% nationally (elite), and (2) EBI representative of the national average (NA). In each year, 90 elite and 45 NA cows were randomly allocated to 1 of 3 FT: control, lower grass allowance, and high concentrate. No interaction between GG and FT was observed for any of the measures of fertility investigated. The elite cows achieved significantly greater pregnancy rate to first service (+14.9 percentage points), and significantly greater pregnancy rates after 21, 42, and 84 d of breeding (+17.3, +15.2, and +9.6 percentage points, respectively) compared with NA. The number of services per cow was fewer for elite (1.57) compared with NA (1.80). The interval from mating start date to pregnancy was significantly shorter for elite cows compared with NA. The elite cows maintained greater mean body condition score than NA throughout the study (2.91 vs. 2.72), and had greater body condition score at calving, artificial insemination, and drying off compared with NA. The elite cows had greater mean circulating concentrations of insulin-like growth factor-1 compared with NA. No significant effect was observed of GG on commencement of luteal activity, or progesterone profile variables. Greater survival to the start of fifth lactation was observed for elite cows. The elite cows were 43% less likely to be culled than NA by the beginning of the fifth lactation. The results highlight the success of the Economic Breeding Index to deliver reproductive performance and longevity consistent with industry targets across a range of seasonal pasture-based FT. The results also clearly demonstrate the potential of appropriate genetic selection to reverse negative fertility trends incurred during previous decades of selection for milk production alone.

Abstract
This guideline was designed to provide service providers and users with an evidence-based set of current best practice guidelines for people and their families and carers, living with epidermolysis bullosa (EB). A systematic literature review relating to the podiatric care of patients with EB was undertaken. Search terms were used, for which the most recent articles relating to podiatric treatment were identified from as early as 1979 to the present day, across seven electronic search engines: MEDLINE, Wiley Online Library, Google Scholar, Athens, ResearchGate, Net and PubFacts.com. The Scottish Intercollegiate Guidelines Network (SIGN) methodology was used. The first guideline draft was analysed and discussed by clinical experts, methodologists and patients and their representatives at four panel meetings. The resulting document went through an external review process by a panel of experts, other healthcare professionals, patient representatives and lay reviewers. The final document will be piloted in three different centres in the U.K. and Australia. Following an EB community international survey the outcomes indicated six main areas that the community indicated as a priority to foot management. These include blistering and wound management, exploring the most suitable footwear and hosiery for EB, management of dystrophic nails, hyperkeratosis (callus), maintaining mobility and fusion of toes (pseudosyndactyly). The evidence here is limited but several interventions currently practised by podiatrists show positive outcomes.

Abstract
BACKGROUND Active warming during surgery prevents perioperative hypothermia but the effectiveness and postoperative infection rates may differ between warming technologies. AIM To establish the recruitment and data management strategies needed for a full trial comparing postoperative infection rates associated with forced air warming (FAW) versus resistive fabric warming (RFW) in patients aged >65 years undergoing hemiarthroplasty following fractured neck of femur. METHODS Participants were randomized 1:1 in permuted blocks to FAW or RFW. Hypothermia was defined as a temperature of <36°C at the end of surgery. Primary outcomes were the number of participants recruited and the number with definitive deep surgical site infections. FINDINGS A total of 515 participants were randomized at six sites over a period of 18 months. Follow-up was completed for 70.1%. Thirty-seven participants were hypothermic (7.5% in the FAW group; 9.7% in the RFW group). The mean temperatures before anaesthesia and at the end of surgery were similar. For the primary clinical outcome, there were four deep surgical site infections in the FAW group and three in the RFW group. All participants who developed a postoperative infection had antibiotic prophylaxis, a cemented prosthesis, and were operated under laminar airflow; none was hypothermic. There were no serious adverse events related to warming. CONCLUSION Surgical site infections were identified in both groups. Progression from the pilot to the full trial is possible but will need to take account of the high attrition rate.

Abstract
The objective of the current study was to explore differences in dry matter intake, intake capacity, production efficiency, energy balance, and grazing behavior, of 2 divergent genetic groups (GG) of lactating Holstein-Friesian, selected using the Irish Economic Breeding Index (EBI). The GG were evaluated across 3 spring calving pasture-based feeding treatments (FT) over 3 yr. The 2 divergent GG were (1) high EBI, representative of the top 5% nationally (elite), and (2) EBI representative of the national average (NA). In each year 90 elite and 45 NA cows were randomly allocated to 1 of 3 FT: control, lower grass allowance, and high concentrate. Although FT did affect animal performance, there were few notable incidences of GG × FT interaction. The elite cows expressed lower daily milk yield (-1 kg) compared with NA. Elite cows did, however, express higher daily concentrations of milk fat (+3.7 g/kg) and protein (+2.1 g/kg) compared with NA. Daily yield of milk solids and net energy of lactation (NEL) was similar for both GG. Body weight (BW) was greater for NA (+13 kg) compared with elite, whereas mean body condition score was greater (+0.14) for elite compared with NA. Intake did not differ significantly between GG. Intake capacity, expressed as total dry matter intake/100 kg of BW, was greater with elite compared with NA. Production efficiency expressed as yield of milk solids per 100 kg of BW was greater with elite compared with NA, although milk solids/total dry matter intake did not differ between GG. Expressed as NEL as a proportion of net energy intake minus net energy of maintenance (NEL/NEI - NEM) and NEI/milk solids kg, indicated a slight reduction in the utilization of ingested energy for milk production with elite compared with NA. This is, however, suggested as favorable as it manifested as a more positive energy balance with elite compared with NA and so is likely to enhance robustness, increase longevity, and increase overall lifetime efficiency. Noteworthy was a consistent numerical trend toward more intense grazing activity with elite compared with NA cows, exhibited in the numerically greater grazing time (+19 min) and total number of bites per day (+2,591).

The objective of this study was to validate the effect of genetic improvement using the Irish genetic merit index, the Economic Breeding Index (EBI), on total lactation performance and lactation profiles for milk yield, milk solids yield (fat plus protein; kg), and milk fat, protein, and lactose content within 3 pasture-based feeding treatments (FT) and to investigate whether an interaction exists between genetic group (GG) of Holstein-Friesian and pasture-based FT. The 2 GG were (1) extremely high EBI representative of the top 5% nationally (referred to as the elite group) and (2) representative of the national average EBI (referred to as the NA group). Cows from each GG were randomly allocated each year to 1 of 3 pasture-based FT: control, lower grass allowance, and high concentrate. The effects of GG, FT, year, parity, and the interaction between GG and FT adjusted for calving day of year on milk and milk solids (fat plus protein; kg) production across lactation were studied using mixed models. Cow was nested within GG to account for repeated cow records across years. The overall and stage of lactation-specific responses to concentrate supplementation (high concentrate vs. control) and reduced pasture allowance (lower grass allowance vs. control) were tested. Profiles of daily milk yield, milk solids yield, and milk fat, protein, and lactose content for each week of lactation for the elite and NA groups within each FT and for each parity group within the elite and NA groups were generated. Phenotypic performance was regressed against individual cow genetic potential based on predicted transmitting ability. The NA cows produced the highest milk yield. Milk fat and protein content was higher for the elite group and consequently yield of solids-corrected milk was similar, whereas yield of milk solids tended to be higher for the elite group compared with the NA group. Milk lactose content did not differ between GG. Responses to concentrate supplementation or reduced pasture allowance did not differ between GG. Milk production profiles illustrated that elite cows maintained higher production but with lower persistency than NA cows. Regression of phenotypic performance against predicted transmitting ability illustrated that performance was broadly in line with expectation. The results illustrate that the superiority of high-EBI cattle is consistent across diverse pasture-based FT. The results also highlight the success of the EBI to deliver production performance in line with the national breeding objective: lower milk volume with higher fat and protein content.

Abstract
Prolonged or severe stress can adversely affect older adults' cognitive function, but population-based studies investigating this relationship over time are rare. Previous studies have largely focused on stress either evaluated at a single time point or linked to specific life events. This study aimed to investigate whether a change in perceived stress over 2 years predicts a change in cognitive performance over the same time period in a population-based sample of older adults. Data from the first 2 waves of The Irish Longitudinal Study on Ageing were analyzed. Five thousand and seventy adults aged 50 and older completed the 4-item Perceived Stress Scale and measures of verbal fluency, immediate and delayed word recall 2 years apart. A first differences regression model revealed that the change in stress over 2 years was inversely associated with a change in immediate word recall performance, even after adjustment for change in possible confounders (B = -0.030, 95% CI [-.056, -.004], p < .05). No association was observed for delayed recall or verbal fluency performance. Change in perceived stress is inversely correlated with change in immediate recall, even over a short period. Stress modifying interventions could potentially reduce the risk of cognitive decline associated with ageing.

Abstract
We have developed an InAs/InP quantum dot (QD) C-band coherent comb laser (CCL) module with actively stabilized absolute wavelength and power, and channel spacing of 34.462 GHz with ± 100 ppm accuracy. The total output power is up to 46 mW. The integrated average relative intensity noise (RIN) values of the lasing spectrum and a filtered single channel at 1540.19 nm were -165.6 dB/Hz and -130.3 dB/Hz respectively in the frequency range from 10 MHz to 10 GHz. The optical linewidth of the 45 filtered individual channels between 1531.77 nm to 1543.77 nm ranged from 850 kHz to 2.16 MHz. We have also analyzed the noise behaviors of each individual channel.

Abstract
Carcinoid tumours in the abdomen are uncommon, but typically occur in the gastrointestinal tract. Primary renal carcinoid is an extremely rare tumour, poorly described in the literature. We describe an unusual case where an atypical renal mass on imaging led to a preoperative diagnosis of renal carcinoid on imaging guiding biopsy.

Abstract
Root tip fracture can occur during the extraction of teeth. The clinician must then decide to either leave the root fragment in situ, or to attempt its removal. A similar decision is made when retained root fragments are found incidentally on oral radiographs. The prevalence of retained root fragments is reported as 11-37%. This article aims to highlight the risk benefit matrix of the removal or retention of retained root fragments, in light of the present evidence base.

Abstract
Background: Hirschsprung's disease (HD) is characterized by a lack of ganglion cells in the myenteric and submucosal plexus, associated with increased numbers of acetyl cholinesterase (AChE) positive nerve fibres. In approximately 10% of patients with HD the entire colon will be affected; a condition known as Total Colonic Aganglionosis (TCA). Aganglionosis of the appendix has long been considered to be an important finding in a patient in whom TCA is suspected, but its reliability for diagnosis has seldom been discussed. The aim of our study was to assess the reliability of the appendix as a histological specimen for the diagnosis of TCA, and to evaluate the long-term outcome of TCA.
Methods: A retrospective cohort study was performed of all pathological specimens of patients with confirmed HD in our institution between March 2006 and April 2016.
Results: Out of a total of 91 patients identified, 15 patients also had histopathological analysis of the appendix. Nine of these cases were confirmed as having TCA. The remaining 6 patients had HD involving the rest of the bowel up to the ascending colon, with normal ganglion present in the caecum. The appendix was removed in all the 15 cases. All 9 patients with confirmed TCA had aganglionosis of the appendix as well. The remaining 6 cases of short and long segment HD not involving the caecum, demonstrated normal ganglion cells within the appendix.
Conclusion: Aganglionosis of the appendix is a reliable tool in the diagnosis of TCA. The authors recommend that at the time of levelling biopsies, if aganglionosis extends to the mid-transverse colon, an ileostomy be performed and appendix sent for definitive confirmation of TCA. However, at the time of definitive surgery, a frozen section of pull-through segment of bowel is recommended to confirm the presence of ganglion cells.

Abstract
Since its foundation by remarkably talented and insightful individuals, prominently including Pepper Dehner, pediatric soft tissue tumor pathology has developed at an immense rate. The morphologic classification of tumoral entities has extensively been corroborated, but has also evolved with refinement or realignment of these classifications, through accruing molecular data, with many derivative ancillary diagnostic assays now already well-established. Tumors of unclear histogenesis, classically morphologically undifferentiated, are prominent amongst pediatric sarcomas, however, the classes of undifferentiated round- or spindle-cell-tumors-not-otherwise-specified are being dismantled gradually with the identification of their molecular underpinnings. Within recent years, for example, numerous subcategories of 'Ewing-like' round cell sarcoma have emerged. Such advances have provided the basis for novel diagnostic and prognostic sub-classifications. Efforts at defining cell- or lineage-of-origin for several tumor types have produced interesting insights especially for rhabdomyosarcoma. The remarkably early onset of pediatric sarcomas defies the theory necessitating stochastic accumulation of several somatic mutations for cancer development and indeed, these tumors may be remarkably genomically stable, often belying their aggressive nature. Much is coming to light recently regarding the role of epigenetic modifications in the evolution of these sarcomas. Indeed the morphologic features of embryonal tumors generally (not just sarcomas) may be highly reminiscent of arrested differentiation, and given the tight epigenetic regulation of cell fate determination and cell identity maintenance, a theory of epigenetically-driven oncogenesis sits easily with these tumors. The age-delimited distinct biologies of 'pediatric' and adult GIST are intriguing, particularly, the SDH-deficient 'pediatric' form, driven by a metabolic defect, but resulting in epigenetic dysregulation with genome-wide DNA methylation changes. There is little doubt that many of the gaps in our understanding of pediatric sarcoma biology will be filled by a deeper appreciation of the role of dysregulated epigenetics including chromatin biology, perhaps best exemplified in malignant rhabdoid tumor. The field of pediatric soft tissue tumor pathology grows ever more interesting. Importantly though, it must be emphasized, that none of this progress could have occurred, or indeed continue, without the initial step of accurate diagnosis, founded solidly on morphology - thank you Pepper for your unparalleled contributions to this field! The opportunity to be your apprentice for five years has been a bigger and more positive influence than words can express.

Abstract
The global terrestrial carbon sink has increased since the start of this century at a time of growing carbon emissions from fossil fuel burning. Here we test the hypothesis that increases in atmospheric aerosols from fossil fuel burning enhanced the diffuse light fraction and the efficiency of plant carbon uptake. Using a combination of models, we estimate that at global scale changes in light regimes from fossil fuel aerosol emissions had only a small negative effect on the increase in terrestrial net primary production over the period 1998-2010. Hereby, the substantial increases in fossil fuel aerosol emissions and plant carbon uptake over East Asia were effectively canceled by opposing trends across Europe and North America. This suggests that if the recent increase in the land carbon sink would be causally linked to fossil fuel emissions, it is unlikely via the effect of aerosols but due to other factors such as nitrogen deposition or nitrogen-carbon interactions.

Abstract
Behaviour change interventions offer clinical pharmacists many opportunities to optimise the use of medicines. 'MINDSPACE' is a framework used by a Government-affiliated organisation in the United Kingdom to communicate an approach to changing behaviour through policy. The Theoretical Domains Framework (TDF) organises constructs of psychological theories that are most relevant to behaviour change into 14 domains. Both frameworks offer a way of identifying what drives a change in behaviour, providing a target for an intervention. This article aims to compare and contrast MINDSPACE and the TDF, and serves to inform pharmacy practitioners about the potential strengths and weaknesses of using either framework in a clinical pharmacy context. It appears that neither framework can deliver evidence-based interventions that can be developed and implemented with the pace demanded by policy and practice-based settings. A collaborative approach would ensure timely development of acceptable behaviour change interventions that are grounded in evidence.

Abstract
Most people are unable to detect accurately when others are lying. Many explanations for this inability have been suggested but the cognitive heuristics involved in lie detection have received little attention. The present study offers evidence from two experiments, based on two different groups of observers, judging two different kinds of lies, presented in two different testing situations, that the fundamental attribution error significantly undermines the ability to detect honesty and deception accurately. Trait judgments of trustworthiness were highly correlated with state judgments of truthfulness, leading, as predicted, to positive correlations with honest detection accuracy and negative correlations with deception detection accuracy. More accurate lie detectors were significantly more likely than less accurate lie detectors to separate state and trait judgments of honesty. The effect of other biases, such as the halo effect and the truthfulness bias, also are examined. Implications for future research and practice are discussed.

Abstract
Research suggests that most people cannot tell from demeanor when others are lying. Such poor performance is typical not only of laypeople but also of most professionals concerned with lying. In this study, three professional groups with special interest or skill in deception, two law-enforcement groups and a select group of clinical psychologists, obtained high accuracy in judging videotapes of people who were lying or telling the truth about their opinions. These findings strengthen earlier evidence that some professional lie catchers are highly accurate, and that behavioral clues to lying are detectable in real time. This study also provides the first evidence that some psychologists can achieve high accuracy in catching lies.

Abstract
Non-Hodgkin's lymphoma (NHL) is a relatively common childhood cancer that can present in a myriad of ways. It is essential that NHL is included in the differential diagnosis of children presenting with an abdominal complaint, especially those with unexplained or prolonged symptoms. We describe three acute pediatric presentations of abdominal NHL, two of which presented as acute abdomen (the first mimicking intussusception and the second appendicitis), and the third involving lower limb edema. This case series illustrates the array of presentations of abdominal NHL and the diagnostic challenges that they can provide.
