Abstract
BACKGROUND Healthcare workers (HCWs) had a greater occupational risk of exposure to coronavirus disease 2019 (COVID-19) and reported higher rates of long COVID (LC). This has implications for the provision of health care in already stretched health services. AIMS This study explored the impact of LC on a range of UK National Health Service (NHS) HCWs, their health and well-being, the effect on work patterns, and occupational support received. METHODS Mixed-methods study, online survey and qualitative interviews. Participants self-reporting LC symptoms were recruited through social media and NHS channels. Interviews used maximum variation sampling of 50 HCWs including healthcare professionals, ancillary and administration staff. Thematic analysis was conducted using NVivo software. RESULTS A total of 471 HCWs completed the online survey. Multiple LC symptoms were reported, revealing activity limitations for 90%. Two-thirds had taken sick leave, 18% were off-work and 33% reported changes in work duties. There were few differences in work practices by occupational group. Most participants were working but managing complex and dynamic symptoms, with periods of improvement and exacerbation. They engaged in a range of strategies: rest, pacing, planning and prioritizing, with work prioritized over other aspects of life. Symptom improvements were often linked to occupational medicine, managerial, colleague support and flexible workplace adjustments. CONCLUSIONS LC has a significant impact on the lives of HCWs suffering prolonged symptoms. Due to the variability and dynamic nature of symptoms, workplace support and flexible policies are needed to help retain staff.

Abstract
PURPOSE/OBJECTIVE(S) A recently developed advanced kVCBCT system, designed for simulation and planning, includes improvements to the imaging panel and reconstruction technique, enabling more accurate electron density mapping than a typical CBCT. This study investigates the accuracy, limitations, and dosimetric impact of this new system. MATERIALS/METHODS CBCT images were taken of both large (pelvis) and small (head) electron density phantoms with inserts ranging from lung (0.29) to cortical bone (1.69). Images were taken with several pre-set protocols with energies of 125 kVp and 140 kVp. The effects of longitudinal buildup (for scatter due to the cone-beam geometry) and blade position were also investigated. The HU values of each insert were measured over a small region of interest. Several electron density curves were generated - pelvis protocol on the large phantom, head protocol on the small phantom, and average - and imported into a treatment planning system. Dose calculation was performed using each curve and differences were observed. RESULTS HU to electron density mapping was sensitive to the use of longitudinal buildup and blade position, with differences in the curves observed at both low and high electron densities, due to imager saturation effects not found in typical clinical scenarios. Subsequent studies used both longitudinal buildup and fully opened blades. Under these conditions, mapping was not sensitive to technique or phantom size at low electron densities. At higher values, the curves diverged, with the head protocol showing higher HU values and the pelvis protocol showing lower. The average curve matched very closely with the curve from our standard CT simulator. Dose calculation showed little dependence on the curve chosen, with max point dose differences of 1.2% between the pelvis and average scans, though most of the plan was <0.5% different. Results for the head protocol were similar. CONCLUSION The system provides reliable HU values comparable to a CT simulator, though it is important to consider the effects of imager saturation by choosing appropriate scatter and collimation. The calibration is slightly sensitive to the choice of phantom size and beam energy, though these differences led to negligible (<0.5%) differences in dose calculation accuracy.

Abstract
PURPOSE/OBJECTIVE(S) An advanced kV-CBCT imaging system mounted on a high-speed ring-gantry Linac has recently been introduced, offering improved imaging hardware and reconstruction software to produce high quality CBCT images usable for treatment planning. Imaging performance of the system was assessed using the American College of Radiology (ACR) accreditation designed for diagnostic CT systems, additionally comparing its results to pre-existing diagnostic CT and Linac-based CBCT systems. MATERIALS/METHODS All imaging protocols on the novel imaging system were scanned with the ACR head phantom and evaluated using ACR recommended testing and passing criteria. ACR image quality parameters include contrast-to-noise ratio (CNR), spatial resolution, HU accuracy, image scaling, and HU uniformity. CNR ≥1.0 for adult head and body, ≥0.7 for pediatric head, and ≥0.4 for pediatric body imaging protocols pass ACR criteria. Spatial resolution ≥6 line-pairs/cm for head and ≥5 line-pairs/cm for body protocols pass ACR criteria. HU accuracy passing criteria includes acrylic (110 to 135 HU), air (-1005 to -970 HU), bone (850 to 970 HU), polyethylene (-107 to -84 HU), and water (-7 to 7 HU). Image scaling measurements with errors ≤5% and HU uniformity maximum differences ≤5 HU pass ACR criteria. For machine cross-comparisons, adult Head and Pelvis imaging protocols were acquired on an existing diagnostic CT and 2 Linac-based CBCT systems (1 traditional C-arm and 1 ring-gantry) and analyzed with the same ACR methodology and passing criteria, with passing rates compared. RESULTS On the novel imaging system, all standard patient size imaging protocols using 125 kVp (Head, H&N, Thorax, Thorax Slow, Breast, Abdomen, Pelvis, Pediatric Head, and Pediatric Abdomen) passed all ACR criteria; while 2 larger patient focused imaging protocols using 140 kVp (Abdomen Large and Pelvis Large) produced minor deviations on HU uniformity (maximum differences of 5 - 7 HU) but passed all other ACR criteria. The novel system matched passing rates of a diagnostic CT simulator, and outperformed pre-existing Linac based CBCT imaging systems. CONCLUSION This newly developed advanced imaging system produces high quality images, meeting diagnostic CT ACR recommendations and far surpassing the CBCT image quality currently available on pre-existing Linacs.

Abstract
Abstract
Introduction
The insertion of a foreign body in the urethra is an uncommon urological emergency. A wide variety of inserted objects have been described, presenting either asymptomatically or with lower abdominal discomfort and lower urinary tract symptoms. Sexual experimentation and gratification as well as mental disorders are considered the main underlying causes. The aim of this report is to present the case of a USB wire self-insertion and its challenging urological management.
Case Presentation
A 15-year-old male patient presented to his local Accident and Emergency department with gross haematuria following self-insertion of the knotted cable of a USB wire into his urethra in the context of sexual experimentation. Endoscopic approach via rigid cystoscopy and optical urethrotomy was not effective. A suprapubic catheter was inserted, and the patient was urgently transferred to our hospital for tertiary management.
Following radiological assessment to confirm the position of the wire, a longitudinal peno-scrotal incision over the palpable foreign body was made. Urethrotomy revealed the knotted cable in the proximal aspect of the penile urethra, which was cut and removed. Urethra was subsequently closed over a urethral catheter. Postoperative recovery was uneventful, and patient was discharged home with oral antibiotics. Urethral catheter was removed following normal fluoroscopic assessment of the urethra two weeks later.
Conclusions
The management of a foreign urethral body can be challenging and usually requires tertiary expertise to achieve optimal outcomes. Poor initial management could potentially lead to devastating long-term complications such as urethral strictures and fistulas.

Abstract
BACKGROUND Prolonged field care is required when casualty evacuation to a surgical facility is delayed by distance, weather or tactical constraints. This situation can occur in both civilian and military environments. In these circumstances, there are no established treatment options for extremity compartment syndrome. Telementoring by a surgeon may enable the local clinician to perform a fasciotomy to decompress the affected compartments. METHODS Six military clinicians were asked to perform a two-incision leg fasciotomy in synthetic models under the guidance of an orthopaedic surgeon located 380 km away. Communication occurred through commercially available software and smartglasses, which also allowed the surgeon to send augmented-reality graphics to the operators. Two blinded surgeons evaluated the specimens according to objective criteria. Control specimens were added to ensure the integrity of the evaluation process. RESULTS The six study participants were military physician assistants who had extensive clinical experience but had never performed a fasciotomy. The average duration of the procedure was 53 min. All six procedures were completed without major errors: release of all four compartments was achieved through full-length incisions in the skin and fascia. The only surgical complication was a laceration of the saphenous vein. All three control specimens were correctly assessed by the evaluators. None of the participants experienced adverse effects from wearing the smartglasses. Four dropped calls occurred, but the connection was re-established in all cases. CONCLUSION All six surgical procedures were completed successfully. We attribute the dropped calls to a mismatch between the size of the graphic files and the available bandwidth. A better technical understanding of the software by the mentoring surgeon would have avoided this problem. Important considerations for future research and practice include protocols for dropped communications, surgical skills training for the operators and communication training for the surgeons.

Abstract
Abstract
Background
Mortality for Intracerebral haemorrhage (ICH) is 31% (Irish National Audit Stroke, 2019). An ICH care bundle focusing on acute anticoagulation reversal, blood pressure lowering, and a neurosurgical care pathway was associated with improved survival. Translating evidence-based medicine into clinical practice is challenging. The aim of this study was to determine feasibility and outcomes of implementation of a care bundle.
Methods
An ICH care bundle was developed using an iterative process involving expert stakeholder review of the evidence-based literature. A pre-and-post quasi-experimental research design was employed to evaluate this intervention. Baseline data were collected before implementation (January 2016-June 2018). Implementation took place in a staged manner in a single university teaching hospital with multiple ‘Plan Do Study Act cycles’ (June 2018 to January 2021). Data on compliance, process measures and outcomes were collected.
Results
Systolic blood pressure (first 24-hours) and anticoagulant reversal were significantly better controlled post-implementation (χ2 (1, N = 91) = 5.34, P = 0.02), (χ2 (1, N = 25) = 5.85, P = 0.016), respectively. DNAR orders were significantly lower in the post-implementation group (χ2 (1, N = 25) = 5.85, P = 0.029). However, ‘Do Not Actively Resuscitate’ status did not significantly differ when accounting for low GCS as a surrogate measure for poor prognosis (χ2 (1, N = 34) = 0.00, P = 0.966). Modified Rankin Scale on discharge did not differ significantly pre-and-post-implementation (z = −0.075, P = 0.94). A greater proportion of patients survived in the post-implementation group; however, this was not statistically significant (χ2 (1, N = 133) = 0.77, P = 0.38). Length of stay significantly increased post implementation.
Conclusion
An ICH care bundle was developed based on expert stakeholder feedback. The feasibility of implementing this bundle of care was demonstrated in a real-world clinical practice setting. A cluster-randomized trial or a large registry study is the next step to evaluate the overall impact of this care bundle on patient outcomes.

Abstract
Abstract
Background
Stroke is a leading cause of death and disability. Thrombolysis with intravenous (IV) alteplase is the mainstay management of ischaemic stroke. It has a narrow therapeutic window with a high potential for adverse outcomes such as intracranial haemorrhage. The efficacy of alteplase is time and dose dependent with weight-based dosing. National clinical guidelines recommend a dose of 0.9 mg/kg, up to a maximum of 90 mg. (Irish Heart Foundation Council for Stroke 2015). In most hospitals in Ireland however, patients are not weighed prior to thrombolysis. Time pressure and lack of available suitable equipment are factors.
Methods
This retrospective clinical audit evaluated the dosing of alteplase, estimated and actual weight for a convenience sample of stroke thrombolysis patients treated between 2016–2020 at an Irish University Teaching Hospital.
Results
107 patients were audited (62 males, 45 females). Actual and estimated weights were available in 92/107. Weight was not documented (n = 15) due to severe stroke/palliative management (n = 6) or omission (n = 9). 21% (19/92) received the correct dose of 0.9 mg/kg. A further 54% (50/92) received a dose within the range of 0.81–0.99 mg/kg (±10%). 25% received a dose outside this range (> ± 10%). 11% (10/92) were under-thrombolysed and 14% (13/92) over-thrombolysed. 17/92 patients had an intracranial haemorrhage. 35% (n = 6/17) of patients who had an intracranial haemorrhage received a higher dose of thrombolysis (>10%).
Conclusion
A quarter of patients received inappropriate dosing of alteplase that was outside the range of ±10% of 0.9 mg/kg. While stroke thrombolysis must be completed urgently, an accurate weight should be determined to avoid errors in dosing. A process evaluation of stroke thrombolysis would provide information on how best to incorporate an objective means of weight measurement without delaying treatment.

Abstract
Abstract
Aim
To develop a model of clinical factors that may predict: (1) technically and clinically successful embolization of a bleeding vessel at Digital Subtraction Angiography (DSA) for lower gastrointestinal bleed (LGIB); (2) a negative DSA in the presence of positive CT-mesenteric angiography (CTMA) for LGIB.
Method
A retrospective cohort study of all DSAs conducted with intent for embolization for acute LGIB over a 10-year period was undertaken. Pre-procedural and intra-procedural clinical variables were evaluated using uni- and multi-variate analysis.
Results
123 DSAs were evaluated. Technical success was 81% (64/78) with clinical success 78%. Technical success was associated with super-selective approach, contrast extravasation on CT, haemoglobin drop, anatomical source and time from CT to DSA on univariate analysis. On multivariate analysis time from CT to DSA was significant with a higher success probability within 120 minutes with different factors being salient depending on degree of delay. Clinical success was only associated with APTT (<27.5s). Technical failure from a negative DSA following a positive CTMA was associated with anatomical source, haemodynamic stability, platelet count and time from CT to DSA on univariate analysis. The latter three remained so on multivariate analysis.
Conclusions
A triaging approach to utilising emergency DSA may be helpful. If prolonged delay between a positive CT and DSA is anticipated, with haemodynamic stability and a near normal platelet count, the DSA may not be fruitful. Technical success may be more likely if DSA occurs within 120mins. Clinical success may be more likely if APTT is within normal range.

Abstract
Introduction Voluntary medical male circumcision (VMMC) is a scientifically proven HIV prevention intervention. Uganda, like many countries has been implementing VMMC for over 10 years but uptake is still low especially in northern Uganda. To attain 80% needed for public health impact, scale-up was recommended with many innovations implemented with sub-optimal results. This study therefore wanted to find out some of the correlates of VMMC uptake in Gulu district, northern Uganda. Methods Two studies were conducted separately but data was analyzed for this study. For the quantitative study, proportions and frequencies were used to measure perception of increased risk of HIV infection using age, gender, occupation, marital and circumcision status. Qualitative study provided data from FGDs, IDIs and KIIs were first transcribed in Acholi and then translated in English. Transcripts were uploaded in MAXDQA software for data management. A code book for emerging themes was developed. Results A total of 548 respondents were interviewed for the quantitative study, where two thirds (66%) of the participants perceived themselves to be at increased risk of HIV infection. For the qualitative study, 149 participants from 19 FGDs, 11 KIIs and 9 IDIs were interviewed. Data were analyzed thematically using both inductive and deductive approaches. Devices were preferred to conventional surgery while mobile services were preferred to static services. However, there were divergent views regarding circumcision service providers' socio-demographics and these were influenced mainly by age, level of education and location. Conclusion People in Northern Uganda perceived themselves to be at an increased risk of HIV infection. They preferred devices to conventional surgery, mobile services to static services but had varying views about the socio-demographics of the service providers.

Abstract
INTRODUCTION Anal squamous cell carcinoma (ASCC) is a rare malignancy with rising incidence rates. Risk factors include human immunodeficiency virus (HIV) infection, high-risk sexual activity and HPV-related genitourinary dysplasia/neoplasia. There is an overlap between high-risk patients and those attending HIV Medicine/Sexual Health (HMSH) services. We hypothesised that HMSH involvement may facilitate earlier referral to colorectal surgeons, with better outcomes. METHODS Retrospective review of all ASCC and anal intraepithelial neoplasia (AIN) treated at a tertiary-referral hospital with a dedicated HMSH clinic between 2000 and 2018. Comparative analysis was performed of demographics, management and outcomes between HMSH and non-HMSH patients. RESULTS One hundred and nine patients had anal pathology, eighty-five with ASCC (78%) and twenty-four with AIN (22%). Seventy (64%) were male. Median (range) age at ASCC diagnosis was 51 years (26-88). Thirty-six percent of all patients attended HMSH services, 28% were HIV positive, and 41% of males were men-who-have-sex-with-men (MSM). Eighty-one ASCC patients (97.5%) were treated with curative intent. Sixty-seven (80%) had primary chemoradiation therapy. Fifteen (17.5%) had primary surgical excision. Twelve (14%) developed recurrent disease. Ultimately, seven required salvage APR. Overall 3-year survival (3YS) was 76%. HMSH patients were significantly younger at ASCC diagnosis (p < 0.001), with a higher prevalence of HIV, HPV and MSM. HMSH attenders also tended to be diagnosed at earlier stages, were less likely to develop recurrence and achieved better overall outcomes, with a superior overall 3YS than non-HMSH patients (92% vs 72%, p = 0.037). CONCLUSION ASCC incidence is increasing worldwide. The HMSH cohort has emerged as a distinct subpopulation of younger, high-risk, male patients. Collaboration between HMSH and colorectal surgeons offers an opportunity for risk reduction strategies and earlier intervention.

Abstract
Abstract
Background
Period poverty refers to a lack of access to safe means of managing menstruation. It affects the education, health and dignity of millions of women and girls globally. This study aims to identify the barriers facing menstruating girls in rural Uganda, investigate the effects of period poverty in this demographic and assess the need to implement a programme to tackle challenges identified.
Methods
A qualitative study was undertaken in a community setting. 42 Participants were selected in Bududa, Uganda using convenience sampling. School-age girls supported by The Shelo Foundation (charity no.1155142) who had begun menstruating and adults in positions of responsibility in the community were interviewed to gain a cross sectional understanding of the questions posed. Data was collected prospectively in semi-structured interviews over a four-week period in July 2013. Questions focused on access to essential hygiene materials, challenges faced when menstruating (with a focus on accessing education) and possible solutions to the barriers reported. Interview transcripts were analysed; the common concepts were identified, and conclusions drawn from the results.
Results
Inability to access sanitation products, due to financial poverty and local availability, was the main challenge highlighted throughout the analysis of the interview transcripts. The other common themes included lack of suitable hygiene facilities, absence of education on menstruation and the vulnerability of menstruating girls to abuse and stigma. Analysis found that on average girls were missing three days of school a month due to their periods, equalling 18% of the academic year.
Conclusions
Period poverty disadvantages school-aged females in Bududa, Uganda. Financial poverty, lack of education and stigma contribute to period poverty. An intervention programme including accessible sanitation products and education is recommended to tackle this gender inequality for girls in this population.
Key messages
A lack of sanitation products, subpar education and stigma contribute to period poverty in Uganda and negatively impact female education with menstruating students missing up to 18% of a school year. An intervention programme incorporating access to sanitation products alongside education is recommended to tackle period poverty in this population and improve women’s health and female education.

Abstract
INTRODUCTION This study investigates instances of elevated radiation dose on a radiation tracking system to determine their aetiologies. It aimed to investigate the impact of radiographer feedback on these alerts. METHODS Over two six-month periods 11,298 CT examinations were assessed using DoseWatch. Red alerts (dose length products twice the median) were identified and two independent reviewers established whether alerts were true (unjustifiable) or false (justifiable). During the second time period radiographers used a feedback tool to state the cause of the alert. A Chi-Square test was used to assess whether red alert incidence decreased following the implementation of radiographer feedback. RESULTS There were 206 and 357 alerts during the first and second time periods, respectively. These occurred commonly with CT pulmonary angiography, brain, and body examinations. Procedural documentation errors and patient size accounted for 57% and 43% of false alerts, respectively. Radiographer feedback was provided for 17% of studies; this was not associated with a significant change in the number of alerts, but the number of true alerts declined (from 7 to 3) (χ2 = 4.14; p = 0.04). CONCLUSION Procedural documentation errors as well as patient-related factors are associated with false alerts in DoseWatch. Implementation of a radiographer feedback tool reduced true alerts. IMPLICATIONS FOR PRACTICE The implementation of a radiographer feedback tool reduced the rate of true dose alerts. Low uptake with dose alert systems is an issue; the workflow needs to be considered to address this.

Abstract
Introduction: Autosomal dominant tubulointerstitial kidney disease (ADTKD) is a rare genetic cause of renal impairment resulting from mutations in the MUC1, UMOD, HNF1B, REN, and SEC61A1 genes. Neither the national or global prevalence of these diseases has been determined. We aimed to establish a database of patients with ADTKD in Ireland and report the clinical and genetic characteristics of these families. Methods: We identified patients via the Irish Kidney Gene Project and referral to the national renal genetics clinic in Beaumont Hospital who met the clinical criteria for ADTKD (chronic kidney disease, bland urinary sediment, and autosomal dominant inheritance). Eligible patients were then invited to undergo genetic testing by a variety of methods including panel-based testing, whole exome sequencing and, in five families who met the criteria for diagnosis of ADTKD but were negative for causal genetic mutations, we analyzed urinary cell smears for the presence of MUC1fs protein. Results: We studied 54 individuals from 16 families. We identified mutations in the MUC1 gene in three families, UMOD in five families, HNF1beta in two families, and the presence of abnormal MUC1 protein in urine smears in three families (one of which was previously known to carry the genetic mutation). We were unable to identify a mutation in 4 families (3 of whom also tested negative for urinary MUC1fs). Conclusions: There are 4443 people with ESRD in Ireland, 24 of whom are members of the cohort described herein. We observe that ADTKD represents at least 0.54% of Irish ESRD patients.

Abstract
CLINICAL SCENARIO A 65-year-old man presented with a 12-h history of deteriorating rash. Two weeks previously he had completed a course of neoadjuvant chemotherapy for ductal carcinoma of the breast. On examination there were bullae, widespread atypical targetoid lesions and 15% epidermal detachment. There was no mucosal involvement on presentation, but subsequently it did evolve. Skin biopsy showed subepidermal blistering with epidermal necrosis. This confirmed our clinical diagnosis of overlap Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN). On transfer to intensive care he was anxious and fearful. MANAGEMENT QUESTION What are the psychological impacts of SJS/TEN on this man's life? BACKGROUND SJS and TEN have devastating outcomes for those affected. OBJECTIVES To conduct a Critically Appraised Topic to (i) analyse existing research related to the psychological impact of SJS and TEN and (ii) apply the results to the clinical scenario. METHODS Seven electronic databases were searched for publications focusing on the psychological impact of SJS/TEN on adults over 18 years of age. RESULTS Six studies met the inclusion criteria. Healthcare practitioners' (HCPs') lack of information around the disorder was highlighted. Patients experienced undue stress and fear. Some patients had symptoms aligned to post-traumatic stress disorder (PTSD), anxiety and depression. DISCUSSION AND RECOMMENDATION The evidence suggests that SJS and TEN impact psychologically on patients' lives. Education of HCPs, to address their lack of awareness and information on SJS/TEN, should facilitate their capacity to provide information and support to patients, thereby reducing patient anxiety. On discharge, a follow-up appointment with relevant HCPs to reduce the possibility of PTSD occurring should be considered.

Abstract
Early onset cerebellar Ataxia (EOAc) comprises a large group of rare heterogeneous disorders. Determination of the underlying etiology can be difficult given the broad differential diagnosis and the complexity of the genotype-phenotype relationships. This may change the diagnostic work-up into a time-consuming, costly and not always rewarding task. In this overview, the Childhood Ataxia and Cerebellar Group of the European Pediatric Neurology Society (CACG-EPNS) presents a diagnostic algorithm for EOAc patients. In seven consecutive steps, the algorithm leads the clinician through the diagnostic process, including EOA identification, application of the Inventory of Non-Ataxic Signs (INAS), consideration of the family history, neuro-imaging, laboratory investigations, genetic testing by array CGH and Next Generation Sequencing (NGS). In children with EOAc, this algorithm is intended to contribute to the diagnostic process and to allow uniform data entry in EOAc databases.

Abstract
Abstract
Objective
The relation between personality and postural stability has received little attention. This study addressed whether neuroticism and extraversion are related to changes in postural stability and cognitive functioning during a standing balance task.
Method
Thirty-two healthy young adults completed a personality measure and two cognitive tasks, a 2-back task and a weather prediction task (WPT), both while seated and in tandem stance on a foam mat. Sway was quantified via normalized path lengths, and correlation coefficients were calculated between neuroticism, extraversion and dual task changes in postural stability and cognitive functioning.
Results
Consistent with predictions, higher neuroticism was related to increased dual task sway during the 2-back task, r = 0.40, p = 0.023, and lower extraversion was related to increased dual task sway during the WPT, r = -0.43, p = 0.013.
Conclusions
The results suggest that personality is related to postural stability in healthy young adults and that personality should be considered in the prediction of individuals at risk for falling or in the treatment of individuals with balance difficulties. The task-specific nature of the relation is discussed and may be due to differences in anxiety or underlying brain mechanisms between high neuroticism and low extraversion.

Abstract
The former Eagle and Telbel mine site (hereafter referred to as Joutel mine), located near the town of Joutel in the Nord-du-Québec (Canada) houses a tailings storage facility (TSF) that has been inactive since 1996. Fresh, unweathered tailings (beneath 10-30 cm of oxidized horizon) are characterized by an average sulfide content of 6-7 wt% and an average Fe-Mn-carbonate content of 20-40 wt%. The oxidation of Joutel's tailings under atmospheric conditions resulted in the precipitation of secondary phases such as ferric oxyhydroxides and gypsum. Accumulation of these secondary phases throughout the TSF caused cementation and agglomeration of grains, which decreased the porosity of the material in a horizon below the surface. This horizon, which is referred to as hardpan, is frequently encountered within fine, reactive tailings. Characterizations showed that hardpans have a highly compact texture. The formation of hardpans limits vertical water infiltration and oxygen diffusion and these layers greatly affect the global geochemical behavior of underlying tailings in the Joutel TSF by protecting the unweathered material from oxidation. As a result, the water quality of the TSF is largely controlled by the reactivity of the upper oxidized tailings horizon. Joutel's oxidized tailings showed an acidic behavior early during laboratory kinetic leaching tests despite the near absence of sulfides and neutralizing minerals. However, when unweathered tailings were added under oxidized tailings, the water became neutral and metal leaching rates were reduced. After over a year of laboratory leaching tests, hardpans formed within the columns and the natural phenomenon was reproduced under laboratory conditions.

Abstract
BACKGROUND Home haemodialysis (HHD) has the potential to impact positively on patient outcomes and health resource management. There has been rejuvenated international interest in HHD in recent years. AIM We aimed to review the activity and outcomes of the Irish HHD Programme since inception (2009-16). DESIGN Retrospective review. METHODS Patient data were collected using the national electronic Renal Patient database (eMEDRenal version 3.2.1) and individual centre records. All data were recorded in a coded fashion on a Microsoft Excel Spread-sheet and analysed with Stata SE software. RESULTS One hundred and one patients completed training and commenced HHD; a further fourty-five patients were assessed for HHD suitability but did not ultimately dialyse at home. Twenty patients switched to nocturnal HHD when this resource became available. The switch from conventional in-centre dialysis to HHD led to an increase in the mean weekly hours on haemodialysis (HD) and a reduction in medication burden for the majority of patients. The overall rate of arteriovenous fistula (AVF) as primary vascular access was 62%. Most HHD complications were related to access function or access-related infection. Over the 7-years, 29 HHD patients were transplanted and 9 patients died. No deaths resulted directly from a HHD complication or technical issue. CONCLUSIONS Patient and technique survival rates compared favourably to published international reports. However, we identified several aspects that require attention. A small number of patients were receiving inadequate dialysis and require targeted education. Ongoing efforts to increase AVF and self-needling rates in HD units must continue. Psychosocial support is critical during the transition between dialysis modalities.

Abstract
The origin, distribution and leaching of nitrate (NO3-) from coal waste rock dumps in the Elk Valley, British Columbia, Canada were defined using chemical and NO3- isotope analyses (δ15N- and δ18O-NO3-) of solids samples of pre- and post-blast waste rock and from thick (up to 180m) unsaturated waste rock dump profiles constructed between 1982 and 2012 as well as water samples collected from a rock drain located at the base of one dump and effluent from humidity cell (HC) and leach pad (LP) tests on waste rock. δ15N- and δ18O-NO3- values and NO3- concentrations of waste rock and rock drain waters confirmed the source of NO3- in the waste rock to be explosives and that limited to no denitrification occurs in the dump. The average mass of N released during blasting was estimated to be about 3-6% of the N in the explosives. NO3- concentrations in the fresh-blast waste rock and recently placed waste rock used for the HC and LP experiments were highly variable, ranging from below detection to 241mg/kg. The mean and median concentrations of these samples ranged from 10-30mg/kg. In this range of concentrations, the initial aqueous concentration of fresh-blasted waste rock could range from approximately 200-600mg NO3--N/L. Flushing of NO3- from the HCs, LPs and a deep field profile was simulated using a scale dependent leaching efficiency (f) where f ranged from 5-15% for HCs, to 35-80% for the LPs, to 80-90% for the field profile. Our findings show aqueous phase NO3- from blasting residuals is present at highly variable initial concentrations in waste rock and the majority of this NO3- (>75%) should be flushed by recharging water during displacement of the first stored water volume.

Abstract
Vitiligo is a common depigmenting disorder with profound psychosocial impacts. Previous observational studies have suggested a link between vitiligo and psychiatric morbidity, such as depression. However, variability in study design makes it difficult to quantify accurately the relationship between vitiligo and depression. We aimed to investigate the underlying prevalence and risk of depression among patients with vitiligo. A comprehensive search of MEDLINE, Embase and the Cochrane Library was conducted. Cross-sectional, case-control or cohort studies that assessed the prevalence of depression among patients with vitiligo or the relationship between vitiligo and depression were included. DerSimonian and Laird random-effects models were utilized to calculate the pooled prevalence and relative risks. Publication bias was evaluated by funnel plots and Egger's tests. Twenty-five studies with 2708 cases of vitiligo were included. Based on diagnostic codes, the pooled prevalence of depression among patients with vitiligo was 0·253 [95% confidence interval (CI) 0·16-0·34; P < 0·001)]. Using self-reported questionnaires, the pooled prevalence of depressive symptoms was 0·336 (95% CI 0·25-0·42; P < 0·001). The pooled odds ratio of depression among patients with vitiligo was 5·05 vs. controls (95% CI 2·21-11·51; P < 0·001). Moderate-to-high heterogeneity was observed between the studies. Patients with vitiligo were significantly more likely to suffer from depression. Clinical depression or depressive symptoms can be prevalent, with the actual prevalence differing depending on screening instruments or, possibly, geographical regions. Clinicians should actively evaluate patients with vitiligo for signs/symptoms of depression and provide appropriate referrals to manage their psychiatric symptoms accordingly.

Abstract
Bone metastases in patients with solid tumours (ST) and bone lesions in patients with haematological malignancies (HM) are common. Associated skeletal-related events (SREs) cause severe pain, reduced quality of life and place a burden on health care resources. Bone-targeted agents can reduce the risk of SREs. We evaluated the management of bone metastasis/lesions in five European countries (France, Germany, Italy, Spain and the UK) by an observational chart audit. In total, 881 physicians completed brief questionnaires on 17 193 patients during the observation period, and detailed questionnaires for a further 9303 individuals. Patient cases were weighted according to the probability of inclusion. Although a large proportion of patients with bone metastases/lesions were receiving bisphosphonates, many had their treatment stopped (ST, 19%; HM, 36%) or will never be treated (ST, 18%; HM, 13%). The results were generally similar across the countries, although German patients were more likely to have asymptomatic bone lesions detected during routine imaging. In conclusion, many patients who could benefit from bone-targeted agents do not receive bisphosphonates and many have their treatment stopped when they could benefit from continued treatment. Developing treatment guidelines, educating physicians and increasing the availability of new agents could benefit patients and reduce costs.
