Association of a device-based remote management heart failure pathway with outcomes: TriageHF Plus real-world evaluation. ESC Heart Fail 2024. [PMID: 38712903 DOI: 10.1002/ehf2.14821] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2023] [Revised: 03/08/2024] [Accepted: 04/02/2024] [Indexed: 05/08/2024] Open
Abstract
AIMS Clinical pathways have been shown to improve outcomes in patients with heart failure (HF). Although patients with HF often have a cardiac implantable electronic device, few studies have reported the utility of device-derived risk scores to augment and organize care. TriageHF Plus is a device-based HF clinical pathway (DHFP) that uses remote monitoring alerts to trigger structured telephone assessment for HF stability and optimization. We aimed to evaluate the impact of TriageHF Plus on hospitalizations and describe the associated workforce burden. METHODS AND RESULTS TriageHF Plus was a multi-site, prospective study that compared outcomes for patients recruited between April 2019 and February 2021. All alert-triggered assessments were analysed to determine the appropriateness of the alert and the workload burden. A negative-binomial regression with inverse probability treatment weighting using a time-matched usual care cohort was applied to estimate the effect of TriageHF Plus on non-elective hospitalizations. A post hoc pre-COVID-19 sensitivity analysis was also performed. The TriageHF Plus cohort (n = 443) had a mean age of 68.8 ± 11.2 years, 77% male (usual care cohort: n = 315, mean age of 66.2 ± 14.5 years, 65% male). In the TriageHF Plus cohort, an acute medical issue was identified following an alert in 79/182 (43%) cases. Fifty assessments indicated acute HF, requiring clinical action in 44 cases. At 30 day follow-up, 39/66 (59%) of initially symptomatic patients reported improvement, and 20 (19%) initially asymptomatic patients had developed new symptoms. On average, each assessment took 10 min. The TriageHF Plus group had a 58% lower rate of hospitalizations across full follow-up [incidence relative ratio: 0.42, 95% confidence interval (CI): 0.23-0.76, P = 0.004]. Across the pre-COVID-19 window, hospitalizations were 31% lower (0.69, 95% CI: 0.46-1.04, P = 0.077). CONCLUSIONS These data represent the largest real-world evaluation of a DHFP based on multi-parametric risk stratification. The TriageHF Plus clinical pathway was associated with an improvement in HF symptoms and reduced all-cause hospitalizations.

Donor KIR2DL1 Allelic Polymorphism Influences Posthematopoietic Progenitor Cell Transplantation Outcomes in the T Cell Depleted and Reduced Intensity Conditioning Setting. Transplant Cell Ther 2024; 30:488.e1-488.e15. [PMID: 38369017 PMCID: PMC11056303 DOI: 10.1016/j.jtct.2024.02.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Revised: 01/30/2024] [Accepted: 02/13/2024] [Indexed: 02/20/2024]
Abstract
The majority of established KIR clinical assessment algorithms used for donor selection for hematopoietic progenitor cell transplantation (HPCT) evaluate gene content (presence/absence) of the KIR gene complex. In comparison, relatively little is known about the impact of KIR allelic polymorphism. By analyzing donors of T cell depleted (TcD) reduced intensity conditioning (RIC) HPCT, this study investigated the influence on post-transplant outcome of 2 polymorphic residues of the inhibitory KIR2DL1. The aim of this study was to expand upon existing research into the influence of KIR2DL1 allelic polymorphism upon post-transplant outcome. The effects of allele groups upon transplant outcomes were investigated within a patient cohort using a defined treatment protocol of RIC with TcD. Using phylogenetic data, KIR2DL1 allelic polymorphism was categorized into groups on the basis of variation within codons 114 and 245 (positive or negative for the following groups: KIR2DL1*002/001g, KIR2DL1*003, KIR2DL1*004g) and the identification of null alleles. The influence of these KIR2DL1 allele groups in hematopoietic progenitor cell transplantation (HPCT) donors was assessed in the post-transplant data of 86 acute myelogenous leukemia patients receiving RIC TcD HPCT at a single center. KIR2DL1 allele groups in the donor significantly impacted upon 5-year post-transplant outcomes in RIC TcD HPCT. Donor KIR2DL1*003 presented the greatest influence upon post-transplant outcomes, with KIR2DL1*003 positive donors severely reducing 5-year post-transplant overall survival (OS) compared to those receiving a transplant from a KIR2DL1*003 negative donor (KIR2DL1*003 pos versus neg: 27.0% versus 60.0%, P = .008, pc = 0.024) and disease-free survival (DFS) (KIR2DL1*003 pos versus neg: 23.5% versus 60.0%, P = .004, pc = 0.012), and increasing 5-year relapse incidence (KIR2DL1*003 pos versus neg: 63.9% versus 27.2%, P = .009, pc = 0.027). KIR2DL1*003 homozygous and KIR2DL1*003 heterozygous grafts did not present significantly different post-transplant outcomes. Donors possessing the KIR2DL1*002/001 allele group were found to significantly improve post-transplant outcomes, with donors positive for the KIR2DL1*004 allele group presenting a trend towards improvement. KIR2DL1*002/001 allele group (KIR2DL1*002/001g) positive donors improved 5-year OS (KIR2DL1*002/001g pos versus neg: 56.4% versus 27.2%, P = .009, pc = 0.024) and DFS (KIR2DL1*002/001g pos versus neg: 53.8% versus 25.5%, P = .018, pc = 0.036). KIR2DL1*004 allele group (KIR2DL1*004g) positive donors trended towards improving 5-year OS (KIR2DL1*004g pos versus neg: 53.3% versus 35.5%, P = .097, pc = 0.097) and DFS (KIR2DL1*004g pos versus neg: 50.0% versus 33.9%, P = .121, pc = 0.121), and reducing relapse incidence (KIR2DL1*004g pos versus neg: 33.1% versus 54.0%, P = .079, pc = 0.152). The presented findings suggest donor selection algorithms for TcD RIC HPCT should consider avoiding KIR2DL1*003 positive donors, where possible, and contributes to the mounting evidence that KIR assessment in donor selection algorithms should reflect the conditioning regime protocol used.

BEEC psychosocial screening at Royal Manchester Children's Hospital. J Pediatr Urol 2024:S1477-5131(24)00243-2. [PMID: 38762401 DOI: 10.1016/j.jpurol.2024.04.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Revised: 04/19/2024] [Accepted: 04/24/2024] [Indexed: 05/20/2024]
Abstract
INTRODUCTION Bladder Exstrophy and Epispadias Complex (BEEC) is associated with psychosocial difficulties. Screening questionnaires, alongside consultation with a clinical psychologist, can help identify children/young people for further assessment and track trends over time to improve service delivery. OBJECTIVE To screen paediatric BEEC patients for a range of general psychosocial difficulties in a multi-disciplinary out-patient clinic setting and compare these results with our previous study and against published norms. STUDY DESIGN The current service evaluation collected data at outpatient BEEC clinic appointments between 2016 and 2022 (2016-2022 sample). Children aged 4-5, 10-11 and 14-15 years and their parents/proxy were asked to complete two standardised psychosocial questionnaires: Paediatric Quality of Life Inventory (PedsQL 4.0 Generic Core and Family Impact Module) and the Strengths and Difficulties Questionnaires (SDQ). 79 children (CYP) and 93 parent/proxy (P/P) responses were recorded. The sample included paired CYP and P/P responses for the PedsQL (n = 67) and SDQ (n = 35). The mean age for CYP was 9.9 years (SD 3.99, range 2-17), 69.8% (n = 120) of responses for male children. RESULTS The percentage of total CYP scores falling within the 'At Risk' category on the PedsQL increased in the 2016-2022 sample compared to our 2015 sample, indicating the prevalence of greater difficulties. Differences between P/P and CYP responses on both the PedsQL and SDQ favoured CYP. Age, gender, and diagnosis appeared to influence certain questionnaire responses, depending on respondent (CYP or P/P). A significant difference between P/P and CYP in the emotional domain of the PedsQL for those aged 13-18 was observed (p = 0.020), with P/P reporting greater difficulties, but this was not seen in the younger age ranges. Physical Health on the PedsQL were significantly lower for children with a cloacal exstrophy diagnosis, in comparison to bladder exstrophy and epispadias. P/P SDQ scores for boys were significantly higher in several domains. CONCLUSIONS The results demonstrate the need for psychosocial screening, providing benchmarking for psychosocial difficulties within this patient group. Results indicate that patients accessing our clinic are reporting a higher level of challenge across psychosocial domains in recent years reflected by the percentage within the 'At Risk' category for psychosocial difficulty. Linked questionnaire data with condition specific information and surgical history would improve service evaluations. CYP reaching clinical thresholds are offered further psychological assessment within the service.

First Accuracy and User-Experience Evaluation of New Continuous Glucose Monitoring System for Hypoglycemia Due to Hyperinsulinism. J Diabetes Sci Technol 2024:19322968241245923.

Abstract
INTRODUCTION Patients with congenital hyperinsulinism (HI) require constant glucose monitoring to detect and treat recurrent and severe hypoglycemia. Historically, this has been achieved with intermittent self-monitoring blood glucose (SMBG), but patients are increasingly using continuous glucose monitoring (CGM). Given the rapidity of CGM device development, and increasing calls for CGM use from HI families, it is vital that new devices are evaluated early. METHODS We provided two months of supplies for the new Dexcom G7 CGM device to 10 patients with HI who had recently finished using the Dexcom G6. Self-monitoring blood glucose was performed concurrently with paired readings providing accuracy calculations. Patients and families completed questionnaires about device use at the end of the two-month study period. RESULTS Compared to the G6, the G7 showed a significant reduction in mean absolute relative difference (25%-18%, P < .001) and in the over-read error (Bland Altman +1.96 SD; 3.54 mmol/L to 2.95 mmol/L). This resulted in an improvement in hypoglycemia detection from 42% to 62% (P < .001). Families reported an overall preference for the G7 but highlighted concerns about high sensor failure rates. DISCUSSION The reduction in mean absolute relative difference and over-read error and the improvement in hypoglycemia detection implies that the G7 is a safer and more useful device in the management of hypoglycemia for patients with HI. Accuracy, while improved from previous devices, remains suboptimal with 40% of hypoglycemia episodes not detected.

Renal hyperparathyroidism- a risk factor in the development of encapsulating peritoneal sclerosis. Front Endocrinol (Lausanne) 2024; 15:1282925. [PMID: 38567303 PMCID: PMC10985182 DOI: 10.3389/fendo.2024.1282925] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Accepted: 03/04/2024] [Indexed: 04/04/2024] Open
Abstract
Background Encapsulating peritoneal sclerosis (EPS) is a rare complication of prolonged peritoneal dialysis (PD) exposure, characterised by peritoneal thickening, calcification, and fibrosis ultimately presenting with life-threatening bowel obstruction. The presence or role of peritoneal calcification in the pathogenesis of EPS is poorly characterised. We hypothesise that significantly aberrant bone mineral metabolism in patients on PD can cause peritoneal calcification which may trigger the development of EPS. We compared the temporal evolution of bone mineral markers during PD in EPS patients with non-EPS long-term PD controls. Methods Linear mixed model and logistic regression analysis were used to compare four-monthly serum levels of calcium, phosphate, parathyroid hormone, and alkaline phosphatase (ALP) over the duration of PD exposure in 46 EPS and 46 controls (PD, non-EPS) patients. Results EPS patients had higher mean calcium (2.51 vs. 2.41 mmol/L) and ALP (248.00 vs. 111.13 IU/L) levels compared with controls (p=0.01 and p<0.001 respectively, maximum likelihood estimation). Logistic regression analysis demonstrated that high serum calcium and phosphate levels during PD were associated with a 4.5 and 2.9 fold increase in the risk of developing EPS respectively. Conclusion High levels of calcium and phosphate in patients on PD were identified to be risk factors for EPS development. Possible reasons for this may be an imbalance of pro-calcifying factors and calcification inhibitors promoting peritoneal calcification which increases peritoneal stiffness. Mechanical alterations may trigger, unregulated fibrosis and subsequent development of EPS. Improved management of secondary hyperparathyroidism during PD may ultimately diminish the EPS risk.

Abstract
INTRODUCTION Outcomes following pancreas transplantation are suboptimal and better donor selection is required to improve this. Vasoactive drugs (VaD) are commonly used to correct the abnormal haemodynamics of organ donors in intensive care units. VaDs can differentially affect insulin secretion positively (dobutamine) or negatively (noradrenaline). The hypothesis was that some VaDs might induce beta-cell stress or rest and therefore impact pancreas transplant outcomes. The aim of the study was to assess relationships between VaD use and pancreas transplant graft survival. METHODS Data from the UK Transplant Registry on all pancreas transplants performed between 2004 and 2016 with complete follow-up data were included. Univariable- and multivariable-adjusted Cox regression analyses determined risks of graft failure associated with VaD use. RESULTS In 2,183 pancreas transplants, VaDs were used in the following numbers of donors: dobutamine 76 (3.5%), dopamine 84 (3.8%), adrenaline 161 (7.4%), noradrenaline 1,589 (72.8%) and vasopressin 1,219 (55.8%). In multivariable models, adjusted for covariates and the co-administration of other VaDs, noradrenaline use (vs non-use) was a strong predictor of better graft survival (hazard ratio [95% confidence interval] 0.77 [0.64-0.94], p = 0.01). CONCLUSIONS Noradrenaline use was associated with better graft survival in models adjusted for donor and recipient variables - this may be related to inhibition of pancreatic insulin secretion initiating pancreatic beta-cell 'rest'. Further research is required to replicate these findings and establish whether relationships are causal. Identification of alternative methods of inducing beta-cell rest could be valuable in improving graft outcomes.

Beta-cell death and dysfunction drives hyperglycaemia in organ donors. Diabetes Obes Metab 2023; 25:3529-3537.

Abstract
BACKGROUND Donor hyperglycaemia following brain death has been attributed to reversible insulin resistance. However, our islet and pancreas transplant data suggest that other mechanisms may be predominant. We aimed to determine the relationships between donor insulin use and markers of beta-cell death and beta-cell function in pancreas donors after brain death. METHODS In pancreas donors after brain death, we compared clinical and biochemical data in 'insulin-treated' and 'not insulin-treated donors' (IT vs. not-IT). We measured plasma glucose, C-peptide and levels of circulating unmethylated insulin gene promoter cell-free DNA (INS-cfDNA) and microRNA-375 (miR-375), as measures of beta-cell death. Relationships between markers of beta-cell death and islet isolation outcomes and post-transplant function were also evaluated. RESULTS Of 92 pancreas donors, 40 (43%) required insulin. Glycaemic control and beta-cell function were significantly poorer in IT donors versus not-IT donors [median (IQR) peak glucose: 8 (7-11) vs. 6 (6-8) mmol/L, p = .016; C-peptide: 3280 (3159-3386) vs. 3195 (2868-3386) pmol/L, p = .046]. IT donors had significantly higher levels of INS-cfDNA [35 (18-52) vs. 30 (8-51) copies/ml, p = .035] and miR-375 [1.050 (0.19-1.95) vs. 0.73 (0.32-1.10) copies/nl, p = .05]. Circulating donor miR-375 was highly predictive of recipient islet graft failure at 3 months [adjusted receiver operator curve (SE) = 0.813 (0.149)]. CONCLUSIONS In pancreas donors, hyperglycaemia requiring IT is strongly associated with beta-cell death. This provides an explanation for the relationship of donor IT with post-transplant beta-cell dysfunction in transplant recipients.

Abstract
Introduction Easypod-connect™ for childhood growth disorders is a unique connected system that enables transmission of injection adherence information for recombinant human growth hormone (r-hGH). Although this system has the potential to facilitate greater adherence, observational studies have shown declining adherence over prolonged periods when used without additional support. Supplemental nurse practitioner support has been envisaged but not investigated; in this study, we have undertaken feasibility analysis of nurse-led virtual reviews (NVR) in combination with easypod-connect™ in a single centre using quantitative and qualitative analyses. Aims We aimed to test feasibility by assessing compliance with NVR, height standard deviation score (SDS) gain, adherence improvement and patient opinions. Methods Patients using easypod™ r-hGH were recruited prospectively to a 12-month study with two telephone NVR appointments in addition to standard of care in-person hospital outpatient visits. A subset was recruited for a semi-structured interview for qualitative thematic analysis. Results Forty-three patients of median (range) age 10.7 (6.7, 15.2) were recruited for a period of 1.1 (0.7, 1.8) years. Thirty-three (76.7%) patients were fully compliant with NVR integration with easypod-connect™, establishing feasibility. Median (inter-quartile range, IQR) height SDS improved from -1.85 (-2.44, -1.37) to -1.48 (-2.14, -1.07) (p<0.001) while adherence remained similar in the majority from study start [96.5 (88.8, 100.0)] to end [99.0 (94.0, 100.0)]. Qualitative analysis identified themes supporting patient benefit: practicalities of appointments, perceived purpose and significance of virtual reviews, and the importance of optimising growth. Four patients complained of injection pain, of whom two switched to an alternative r-hGH device. Conclusion Our study has demonstrated the feasibility of nurse-led virtual review integration with easypod-connect™ in a mixed methods study, laying the foundation for research in larger groups over longer periods. Nurse practitioner supported application of easypod-connect™ offers the potential for improved growth outcomes in all r-hGH devices providing adherence information.

Abstract
Abstract
Background
The aim of this study was to investigate for links between reported pain and inflammation within a sub-cohort of patients undergoing the IPOM plus repair through the measurement of serum/plasma levels of established inflammatory biomarkers in trial participants across 1-year follow up.
Methods
22 patients (12 Protack™ and 10 Reliatack™) within the TACKoMesh randomised controlled trial underwent serial blood sampling as part of their follow up. A panel of pro- and anti-inflammatory biomarkers were assayed using Luminex multiplex assays and ELISAs. Circulating biomarker concentrations were described and compared in the context of clinical and patient reported outcome data that was obtained within the trial.
Results
An increase in the serum concentration of pro- (IL-6 and CRP) and anti- (IL-10) inflammatory biomarkers was seen following IPOM plus repair. Serum IL-6 and CRP were significantly raised compared to baseline at post-operative Days 1, 6 and 30 (p < 0.05). Markers of onward signalling (Cortisol and TNF-alpha) and tissue repair (PDGF-AA and VEGF) showed a trend towards an elevation at similar timepoints (notably at post-op Day 6) but were not significantly different from baseline levels. There were no observed correlations between inflammatory signal and reported pain, treatment allocation within the trial, burden of implanted prosthetic material, or hernia recurrence.
Discussion
This study demonstrates the novel finding of a pro-inflammatory signal at post-operative Day 30 following the IPOM plus repair.

Abstract
Abstract
Background
The aim of this study was to determine the temporal evolution of extracellular matrix (ECM) remodelling and collagen biomarkers and their influence on incisional hernia recurrence after the IPOM plus repair.
Methods
A sub-cohort of patients (n=25) undergoing laparoscopic incisional hernia repair within the TACKoMesh randomised controlled trial were bled at serial timepoints up to 1-year following surgery. Serum/plasma concentration of biomarkers (Procollagen I, Procollagen III, Fibronectin, TGF-beta, MMP-2, MMP-9, TIMP-1, and TIMP-2) were quantified using ELISA and Luminex multiplex techniques. Data were described and compared between groups that developed and remained free from recurrence using R statistical software.
Results
Procollagen I was reduced relative to baseline on post-op Day 1 but increased at Days 6 and 30 (p<0.05). Procollagen III showed an elevation at Day 30. Lower levels of Procollagen I were detected at Day 0, Day 1 and Day 6 (p<0.05) and higher levels of Procollagen III at Day 0, Day 1, Day 6 and Day 30 (p<0.05) in patients with a recurrence.
Fibronectin was reduced at Day 1 and 6 (p<0.05) whilst TGF-β was increased at Day 30 (p<0.05). MMP-2 and its inhibitor TIMP-2 were reduced at post-operative Day 1 (p<0.05). MMP-9 was persistently higher than baseline (p<0.05) at all timepoints. TIMP-1 was elevated at post-op Days 6 and 30. No differences were found in the circulating concentrations of these biomarkers to predict a recurrence.
Conclusion
In patients that developed incisional hernia recurrence, low levels of Procollagen I and high levels of Procollagen III were detected.

Abstract
Abstract
Background
The use of patient reported outcome measures (PROMs) for incisional hernia has been established. This study aims to explore relationships between persistent pain at Day365 post laparoscopic-IPOM repair and other clinical and patient-reported data for patients within the TACKoMESH randomised trial.
Methods
Clinical, operative and PROMs data were collected pre-operatively and at four post-operative time points up to one year. Pain scores were measured using a visual analogue scale (VAS). Quality of life (QoL) data were measured using the short-form 36 (SF-36) and Carolina Comfort Score (CCS). Patients reporting pain ‘at rest’ at Day365 were compared with those reporting no pain. Statistical analysis was undertaken in R studio.
Results
54/63 trial participants attended followed up at Day365; 36 were male, and mean age was 59.1.
10 patients reported persistent pain at Day365 ranging from 1–9 on VAS. Patients were found to have reported higher pre-operative pain scores ‘at rest’ (5 [2–7] vs 0 [0–3] p=0.0181) and ‘on activity’ (8.5 [5–10] vs 4 [2–8] p=0.0181). They reported lower QoL scores in every domain on the SF-36, with significantly lower score for social function (50 [31–50] vs 75 [63–100] p=0.006).
Those reporting persistent pain at Day365 were more likely to have developed hernia recurrence (4 vs 3 p=0.0171). There were no significant differences in baseline characteristics, operative variables, and other complication rates between the groups.
Conclusion
Patients that report persistent pain at Day365 following laparoscopic-IPOM repair are more likely to have reported higher pain and lower QoL scores at pre-operative assessment.

Abstract
Background
A study examining post-op pain, comparing permanent versus absorbable tack fixation devices, Protack™ versus Reliatack™, in IPOM plus repair.
Methods
TACKoMesh is a single-centre double-blind RCT conducted from 2017–2020 with 1-year follow up. Patients were randomised to either Protack™ (titanium tacks) or Reliatack™ (an articulating-arm with dissolvable tacks). Primary outcome was reported pain on activity at Day30. Secondary outcomes include recurrence and quality of life measures (SF-36 & Carolina Comfort Score).
Results
67 patients randomised: 36 with Protack™, 27 with Reliatack™, with 4 conversions. No significant difference in reported pain ‘on activity’ (post-operative Day 1, 6, 30 and 365). There was significantly reduced pain ‘at rest’ on Day1 with Reliatack™ (Protack™ 6 [4 to 9] vs Reliatack™ 4 [3 to 5], p = 0.020) and reduced pain at all other points with Reliatack™.
Operation (p = 0.001) & mesh-fixation (p = 0.001) times were longer, with more knots (p = 0.001) & tacks (p = 0.001) used with Reliatack™.
Entire cohort hernia recurrence, seroma formation, SSI & Clavien-Dindo Grade III-V complication were 8/63 (12.7%), 33/63 (52.4%), 7/63 (11.1%), and 12/63 (19.1%) respectively. There were no significant differences in these outcomes between the treatment groups. CCS showed improvement from post-op Day30 to 365. SF36 showed a reduction in baseline scores at post-op Day30.
Conclusion
There is no difference in reported pain ‘on activity’ following elective IPOM plus hernia repair when choosing either Protack™ or Reliatack™. There is a trend towards improved post-op pain ‘at rest’ with Reliatack™.

Abstract
Aims Provide a report on all patients who underwent laparoscopic incisional hernia repair as part of the TACKoMesh RCT prior to unblinding of treatment arms. Methods Trial recruitment was for primary incisional hernia with a defect diameter of 3–10cm. 63 patients (target 74–136) were operated on prior to the outbreak of COVID-19. Post-operative pain is the primary trial outcome. Surgery was performed with spiral-tack mesh-fixation devices (Protack™ (permanent) or Reliatack™ (absorbable)), Symbotex™ IPOM mesh, and sutured fascial closure using extracorporeal knot ties. Data was collected on trial forms and lifestyle questionnaires (SF-36 and CCS). All data were explored and described in RStudio v1.4.1106. Results Patients were aged 36–80 and 57.1% male. Mean preoperative BMI was 30.91. Mean operating time was 81minutes. In 20.6% patients multiple hernia defects were identified. A good degree of fascial closure was achieved in all patients using a median 3 knots. Median mesh-fixation time was 286seconds and a mean of 25 tacks/patient were used. Median length of hospital stay was 3.5days. Patients were asked “Please indicate on this scale [VAS 0–10] the pain that you currently experience from your incisional hernia during activity?”. Median responses for Day0/pre-op, Day1, Day6, Day30 and Day365 were 4.5, 8.0, 6.0, 3.0 and 1.5 respectively. At one year, 11% patients had experienced hernia recurrence and 52% a post-operative seroma. Conclusions Target recruitment was not possible owing to COVID-19. This technique has comparable recurrence rates. Reported pain increases post-operatively but is reduced at post-operative day30 and day365.

Deep Vein Thrombosis is Common After Cardiac Ablation and Pre-Procedural D-Dimer Could Predict Risk. Heart Lung Circ 2022; 31:1015-1022. [PMID: 35301985 DOI: 10.1016/j.hlc.2022.01.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2021] [Revised: 11/22/2021] [Accepted: 01/13/2022] [Indexed: 10/18/2022]
Abstract
PURPOSE Cardiac catheter ablations are an established treatment for supraventricular tachycardia (SVT) involving prolonged cannulation of the common femoral vein with multiple catheters. This study aimed to identify the risk of deep vein thrombosis (DVT) by studying the frequency of this complication after catheter ablation. METHODS This was a prospective multi-centre cohort study of patients undergoing cardiac ablation for atrioventricular nodal re-entry tachycardia or right-sided accessory atrioventricular connection. Those taking anticoagulation or antiplatelet therapy prior to the procedure were excluded. Following the procedure, bilateral venous duplex ultrasonography from the popliteal vein to the inferior vena cava for DVT was undertaken at 24 hours and between 10 to 14 days. RESULTS Eighty (80) patients (mean age 47.6 yrs [SD 13.4] with 67% female) underwent cardiac ablation (median duration 70 mins). Seven (7) patients developed acute DVT in either the femoral or external iliac vein of the intervention leg, giving a frequency of 8.8% (95% CI 3.6-17.2%). No thrombus was seen in the contralateral leg (p=0.023). An elevated D-dimer prior to the procedure was significantly more frequent in patients developing DVT (42.9% vs 4.1%, p=0.0081; OR 17.0). No other patient or procedural characteristics significantly influenced the risk of DVT. CONCLUSION In patients without peri-procedural anticoagulation catheter ablation precipitated DVT in the catheterised femoral or iliac veins in 8.8% of patients. Peri-procedure prophylactic anticoagulation may be considered for all patients undergoing catheter ablation for SVT. CLINICAL TRIAL REGISTRATION https://clinicaltrials.gov/ct2/show/NCT03877770.

Cortisol Levels During Acute Illnesses in Children and Adolescents: A Systematic Review. JAMA Netw Open 2022; 5:e2217812. [PMID: 35731516 PMCID: PMC9218852 DOI: 10.1001/jamanetworkopen.2022.17812] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/27/2022] [Accepted: 05/02/2022] [Indexed: 12/02/2022] Open
Abstract
Importance Endogenous cortisol levels in children and adolescents during acute illnesses can contribute to the evidence base required to optimize glucocorticoid (GC) stress doses for children and adolescents known to have GC deficiency. Objective To identify endogenous cortisol levels during a range of acute illnesses in children and adolescents without GC deficiency from published evidence. Evidence Review CINAHL, Cochrane Library, Cochrane Database of Systematic Reviews, Embase, and MEDLINE were searched for studies published between January 1, 2000, and June 30, 2020. Two reviewers independently identified relevant studies. Differences were resolved by joint discussion. Inclusion criteria were common acute illnesses, age from 1 month to 18 years, and basal blood cortisol levels obtained within 48 hours of presentation. Studies with fewer than 5 participants and those that included participants known to have GC deficiency or a history of treatment that could affect cortisol levels were excluded from the review. Data for predefined fields were extracted and independently checked by separate pairs of reviewers. Overall weighted means and pooled SDs for cortisol levels were calculated. Findings All 15 studies included were hospital based and included 864 unique participants: 14 studies were prospective observational studies, 1 was part of a trial, and 5 included control individuals. Mean cortisol levels were higher in all participants with an acute illness (n = 689) than in controls (n = 175) (difference in weighted means, 18.95 μg/dL; 95% CI, 16.68-21.22 μg/dL). Cortisol levels were highest in patients with bacterial meningitis (weighted mean [pooled SD], 46.42 [22.24] μg/dL) and were more than 3-fold higher in the group with severe gastroenteritis (weighted mean [pooled SD], 39.64 [21.34] μg/dL) than in the control group. Among the subgroups with sepsis, those with shock had lower cortisol levels than those without shock (weighted mean [pooled SD], 27.83 [36.39] μg/dL vs 37.00 [23.30] μg/dL), but levels in nonsurvivors did not differ from levels in survivors (weighted mean [pooled SD], 24.89 [51.65] μg/dL vs 30.53 [30.60] μg/dL). Conclusions and Relevance This systematic review found that, in children and adolescents without GC deficiency, circulating cortisol levels were higher during acute illnesses than those in controls and also varied across a range of acute illnesses. Whether these levels need to be achieved with exogenous GC stress doses tailored according to the nature and severity of the illness in children and adolescents with GC deficiency warrants investigation.

Abstract
Abstract
Aim
Laparoscopic adrenalectomy is considered the optimal approach for most lesions. Various subsets of minimally invasive adrenalectomy are practiced in the UK, including trans-abdominal (TLA), hand-assisted (HLA) and retroperitoneal (RLA) laparoscopic procedures. We aimed to examine the relative operative outcomes between the 3 techniques.
Methods
We performed a retrospective observational review of contemporaneously maintained databases from two nearby institutions to establish differences in outcomes between minimally invasive adrenalectomy for any size lesion. Statistical analysis was undertaken using R v3.6.0.
Results
Two hundred and ninety-seven patients underwent laparoscopic adrenalectomy and were included in the analysis (45 RLA, 77 HLA and 175 TLA).
There were no significant differences between groups for institution location, wound infection, intra-operative bleeding, blood product requirements, visceral injury, open conversion, re-operation, incisional hernia, laterality of lesion, oncological outcomes and medical complications. Boxplots revealed a wider spread and increased mean operating time for TLA, with less difference in operation time between HLA and RLA groups. This was confirmed by an overall significant finding from Kruskal-Wallis rank sum test (p=<0.001) and pairwise comparisons using Wilcoxon rank sum test with a bonferroni correction for multiple testing which demonstrated significant differences between HLA and TLA, and RLA and TLA (p<0.001), but not between RLA and HLA (p=1.000).
Conclusion
Minimally invasive adrenalectomy can safely be performed by any of 3 techniques. TLA showed a longer mean operating time. The analysis of outcomes revealed otherwise no significant differences in operative or medical outcomes.

Longitudinal assessment of lung clearance index to monitor disease progression in children and adults with cystic fibrosis. Thorax 2021; 77:357-363.

Abstract
Background Lung clearance index (LCI) is a valuable research tool in cystic fibrosis (CF) but clinical application has been limited by technical challenges and uncertainty about how to interpret longitudinal change. In order to help inform clinical practice, this study aimed to assess feasibility, repeatability and longitudinal LCI change in children and adults with CF with predominantly mild baseline disease. Methods Prospective, 3-year, multicentre, observational study of repeated LCI measurement at time of clinical review in patients with CF >5 years, delivered using a rapid wash-in system. Results 112 patients completed at least one LCI assessment and 98 (90%) were still under follow-up at study end. The median (IQR) age was 14.7 (8.6–22.2) years and the mean (SD) FEV1 z-score was −1.2 (1.3). Of 81 subjects with normal FEV1 (>−2 z-scores), 63% had raised LCI (indicating worse lung function). For repeat stable measurements within 6 months, the mean (limits of agreement) change in LCI was 0.9% (−18.8% to 20.7%). A latent class growth model analysis identified four discrete clusters with high accuracy, differentiated by baseline LCI and FEV1. Baseline LCI was the strongest factor associated with longitudinal change. The median total test time was under 19 min. Conclusions Most patients with CF with well-preserved lung function show stable LCI over time. Cluster behaviours can be identified and baseline LCI is a risk factor for future progression. These results support the use of LCI in clinical practice in identifying patients at risk of lung function decline.

Abstract
AIMS/HYPOTHESIS Approximately 50% of organ donors develop hyperglycaemia in intensive care, which is managed with insulin therapy. We aimed to determine the relationships between donor insulin use (DIU) and graft failure in pancreas transplantation. METHODS UK Transplant Registry organ donor data were linked with national data from the UK solid pancreas transplant programme. All pancreas transplants performed between 2004 and 2016 with complete follow-up data were included. Logistic regression models determined associations between DIU and causes of graft failure within 3 months. Area under the receiver operating characteristic curve (aROC) and net reclassification improvement (NRI) assessed the added value of DIU as a predictor of graft failure. RESULTS In 2168 pancreas transplant recipients, 1112 (51%) donors were insulin-treated. DIU was associated with a higher risk of graft loss from isolated islet failure: OR (95% CI), 1.79 (1.05, 3.07), p = 0.03, and this relationship was duration/dose dependent. DIU was also associated with a higher risk of graft loss from anastomotic leak (2.72 [1.07, 6.92], p = 0.04) and a lower risk of graft loss from thrombosis (0.62 [0.39, 0.96], p = 0.03), although duration/dose-dependent relationships were only identified in pancreas transplant alone/pancreas after kidney transplant recipients with grafts failing due to thrombosis (0.86 [0.74, 0.99], p = 0.03). The relationships between donor insulin characteristics and isolated islet failure remained significant after adjusting for potential confounders: DIU 1.75 (1.02, 2.99), p = 0.04; duration 1.08 (1.01, 1.16), p = 0.03. In multivariable analyses, donor insulin characteristics remained significant predictors of lower risk of graft thrombosis in pancreas transplant alone/pancreas after kidney transplant recipients: DIU, 0.34 (0.13, 0.90), p = 0.03; insulin duration/dose, 0.02 (0.001, 0.85), p = 0.04. When data on insulin were added to models predicting isolated islet failure, a significant improvement in discrimination and risk reclassification was observed in all models: no DIU aROC 0.56; DIU aROC 0.57, p = 0.86; NRI 0.28, p < 0.00001; insulin duration aROC 0.60, p = 0.47; NRI 0.35, p < 0.00001. CONCLUSIONS/INTERPRETATION DIU predicts graft survival in pancreas transplant recipients. This assessment could help improve donor selection and thereby improve patient and graft outcomes.

The assessment of a manikin-based low-dose, high-frequency cardiac resuscitation quality improvement program in early UK adopter hospitals. Adv Simul (Lond) 2021; 6:14. [PMID: 33883025 PMCID: PMC8058602 DOI: 10.1186/s41077-021-00168-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2020] [Accepted: 04/04/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Adult and paediatric basic life support (BLS) training are often conducted via group training with an accredited instructor every 24 months. Multiple studies have demonstrated a decline in the quality of cardio-pulmonary resuscitation (CPR) performed as soon as 3-month post-training. The 'Resuscitation Quality Improvement' (RQI) programme is a quarterly low-dose, high-frequency training, based around the use of manikins connected to a cart providing real-time and summative feedback. We aimed to evaluate the effects of the RQI Programme on CPR psychomotor skills in UK hospitals that had adopted this as a method of BLS training, and establish whether this program leads to increased compliance in CPR training. METHODS The study took place across three adopter sites and one control site. Participants completed a baseline assessment without live feedback. Following this, participants at the adopter sites followed the RQI curriculum for adult CPR, or adult and infant CPR. The curriculum was split into quarterly training blocks, and live feedback was given on technique during the training session via the RQI cart. After following the curriculum for 12/24 months, participants completed a second assessment without live feedback. RESULTS At the adopter sites, there was a significant improvement in the overall score between baseline and assessment for infant ventilations (N = 167, p < 0.001), adult ventilations (n = 129, p < 0.001), infant compressions (n = 163, p < 0.001) adult compressions (n = 205, p < 0.001), and adult CPR (n = 249, p < 0.001). There was no significant improvement in the overall score for infant CPR (n = 206, p = 0.08). Data from the control site demonstrated a statistically significant improvement in mean score for adult CPR (n = 22, p = 0.02), but not for adult compressions (N = 18, p = 0.39) or ventilations (n = 17, p = 0.08). No statistically significant difference in improvement of mean scores was found between the grouped adopter sites and the control site. The effect of the duration of the RQI curriculum on CPR performance appeared to be minimal in this data set. Compliance with the RQI curriculum varied by site, one site maintained hospital compliance at 90% over a 1 year period, however compliance reduced over time at all sites. CONCLUSIONS This data demonstrated an increased adherence with guidelines for high-quality CPR post-training with the RQI cart, for all adult and most infant measures, but not infant CPR. However, the relationship between a formalised quarterly RQI curriculum and improvements in resuscitation skills is not clear. It is also unclear whether the RQI approach is superior to the current classroom-based BLS training for CPR skill acquisition in the UK. Further research is required to establish how to optimally implement the RQI system in the UK and how to optimally improve hospital wide compliance with CPR training to improve the outcomes of in-hospital cardiac arrests.

Abstract
OBJECTIVE To assess the diagnostic utility of corneal confocal microscopy (CCM) for diabetic peripheral neuropathy (DPN) and the risk factors for corneal nerve loss. RESEARCH DESIGN AND METHODS A total of 490 participants, including 72 healthy control subjects, 149 with type 1 diabetes, and 269 with type 2 diabetes, underwent detailed assessment of peripheral neuropathy and CCM in relation to risk factors. RESULTS Corneal nerve fiber density (CNFD) (P < 0.0001 and P < 0.0001), corneal nerve fiber branch density (CNBD) (P < 0.0001 and P < 0.0001), and corneal nerve fiber length (CNFL) (P < 0.0001 and P = 0.02) were significantly lower in patients with type 1 and type 2 diabetes compared with control subjects. CNFD (P < 0.0001), CNBD (P < 0.0001), and CNFL (P < 0.0001) were lower in type 1 diabetes compared with type 2 diabetes. Receiver operating characteristic curve analysis for the diagnosis of DPN demonstrated a good area under the curve for CNFD of 0.81, CNBD of 0.74, and CNFL of 0.73. Multivariable regression analysis showed a significant association among reduced CNFL with age (β = -0.27, P = 0.007), HbA1c (β = -1.1; P = 0.01), and weight (β = -0.14; P = 0.03) in patients with type 2 diabetes and with duration of diabetes (β = -0.13; P = 0.02), LDL cholesterol (β = 1.8, P = 0.04), and triglycerides (β = -2.87; P = 0.009) in patients with type 1 diabetes. CONCLUSIONS CCM identifies more severe corneal nerve loss in patients with type 1 diabetes compared with type 2 diabetes and shows good diagnostic accuracy for DPN. Furthermore, the risk factors for a reduction in corneal nerve fiber length differ between type 1 and type 2 diabetes.

Abstract
AIMS The relationship between peri-transplant glycaemic control and outcomes following pancreas transplantation is unknown. We aimed to relate peri-transplant glycaemic control to pancreas graft survival and to develop a framework for defining early graft dysfunction. METHODS Peri-transplant glycaemic control profiles over the first 5 days postoperatively were determined by an area under the curve [AUC; average daily glucose level (mmol/L) × time (days)] and the coefficient of variation of mean daily glucose levels. Peri-transplant hyperglycaemia was defined as an AUC ≥35 mmol/day/L (daily mean blood glucose ≥7 mmol/L). Risks of graft failure associated with glycaemic control and variability and peri-transplant hyperglycaemia were determined using covariate-adjusted Cox regression. RESULTS We collected 7606 glucose readings over 5 days postoperatively from 123 pancreas transplant recipients. Glucose AUC was a significant predictor of graft failure during 3.6 years of follow-up (unadjusted HR [95% confidence interval] 1.17 [1.06-1.30], P = .002). Death censored non-technical graft failure occurred in eight (10%) recipients with peri-transplant normoglycaemia, and eight (25%) recipients with peri-transplant hyperglycaemia such that hyperglycaemia predicted a 3-fold higher risk of graft failure [HR (95% confidence interval): 3.0 (1.1-8.0); P = .028]. CONCLUSION Peri-transplant hyperglycaemia is strongly associated with graft loss and could be a valuable tool guiding individualized graft monitoring and treatment. The 5-day peri-transplant glucose AUC provides a robust and responsive framework for comparing graft function.

Use of Factory-Calibrated Real-time Continuous Glucose Monitoring Improves Time in Target and HbA 1c in a Multiethnic Cohort of Adolescents and Young Adults With Type 1 Diabetes: The MILLENNIALS Study. Diabetes Care 2020; 43:2537-2543. [PMID: 32723843 DOI: 10.2337/dc20-0736] [Citation(s) in RCA: 35] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2020] [Accepted: 06/29/2020] [Indexed: 02/03/2023]
Abstract
OBJECTIVE International type 1 diabetes registries have shown that HbA1c levels are highest in young people with type 1 diabetes; however, improving their glycemic control remains a challenge. We propose that use of the factory-calibrated Dexcom G6 CGM system would improve glycemic control in this cohort. RESEARCH DESIGN AND METHODS We conducted a randomized crossover trial in young people with type 1 diabetes (16-24 years old) comparing the Dexcom G6 CGM system and self-monitoring of blood glucose (SMBG). Participants were assigned to the interventions in random order during two 8-week study periods. During SMBG, blinded continuous glucose monitoring (CGM) was worn by each participant for 10 days at the start, week 4, and week 7 of the control period. HbA1c measurements were drawn after enrollment and before and after each treatment period. The primary outcome was time in range 70-180 mg/dL. RESULTS Time in range was significantly higher during CGM compared with control (35.7 ± 13.5% vs. 24.6 ± 9.3%; mean difference 11.1% [95% CI 7.0-15.2]; P < 0.001). CGM use reduced mean sensor glucose (219.7 ± 37.6 mg/dL vs. 251.9 ± 36.3 mg/dL; mean difference -32.2 mg/dL [95% CI -44.5 to -20.0]; P < 0.001) and time above range (61.7 ± 15.1% vs. 73.6 ± 10.4%; mean difference 11.9% [95% CI -16.4 to -7.4]; P < 0.001). HbA1c level was reduced by 0.76% (95% CI -1.1 to -0.4) (-8.5 mmol/mol [95% CI -12.4 to -4.6]; P < 0.001). Times spent below range (<70 mg/dL and <54 mg/dL) were low and comparable during both study periods. Sensor wear was 84% during the CGM period. CONCLUSIONS CGM use in young people with type 1 diabetes improves time in target and HbA1c levels compared with SMBG.

Donor insulin use predicts beta-cell function after islet transplantation. Diabetes Obes Metab 2020; 22:1874-1879. [PMID: 32452110 DOI: 10.1111/dom.14088] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/23/2020] [Revised: 04/29/2020] [Accepted: 05/10/2020] [Indexed: 01/23/2023]
Abstract
Insulin is routinely used to manage hyperglycaemia in organ donors and during the peri-transplant period in islet transplant recipients. However, it is unknown whether donor insulin use (DIU) predicts beta-cell dysfunction after islet transplantation. We reviewed data from the UK Transplant Registry and the UK Islet Transplant Consortium; all first-time transplants during 2008-2016 were included. Linear regression models determined associations between DIU, median and coefficient of variation (CV) peri-transplant glucose levels and 3-month islet graft function. In 91 islet cell transplant recipients, DIU was associated with lower islet function assessed by BETA-2 scores (β [SE] -3.5 [1.5], P = .02), higher 3-month post-transplant HbA1c levels (5.4 [2.6] mmol/mol, P = .04) and lower fasting C-peptide levels (-107.9 [46.1] pmol/l, P = .02). Glucose at 10 512 time points was recorded during the first 5 days peri-transplant: the median (IQR) daily glucose level was 7.9 (7.0-8.9) mmol/L and glucose CV was 28% (21%-35%). Neither median glucose levels nor glucose CV predicted outcomes post-transplantation. Data on DIU predicts beta-cell dysfunction 3 months after islet transplantation and could help improve donor selection and transplant outcomes.

Totally extraperitoneal repair for the 'sportsman's groin' via 'the Manchester Groin Repair': a comparison of elite versus amateur athletes. Surg Endosc 2020; 35:4371-4379. [PMID: 32909207 DOI: 10.1007/s00464-020-07930-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2020] [Accepted: 08/19/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND Surgery has a recognised role in the treatment of 'sportsman's groin'. This study hypothesises that elite athletes have a superior advantage in both pre- and post-op rehabilitation and therefore will present and resume sporting activities quicker. METHODS A retrospective analysis on a secure database of athletes presenting with groin pain that underwent surgery for 'inguinal disruption'. All data were explored via appropriate descriptive statistics and comparisons made between elite and amateur athletes. RESULTS All patients were male (n = 144). The median age 33 years (range 14-72). The median return to sporting activity was 4.5 weeks (range 2.0-16.0) with one amateur athlete being unable to return to sporting activity. Using the mean of both sides, a comparison of VAS pain scores at pre-operative and 1 month post-operative time points showed a significant reduction (p < 0.001). Comparing 'elite' versus 'amateur' athletes, significant differences were seen in patient age (median 26 vs 40 years; p < 0.001), lead time to clinic presentation (median 62.0 vs 111.5 days; p = 0.004), and time to return to sporting activity (4 vs 5 weeks; p = 0.019). Additional MRI findings within the groin girdle were found in 89 patients (66.4%) and 34 patients (23.6%) had an MRI finding within the adductor tendon. CONCLUSION The Manchester Groin Rrepair is an effective surgical management for 'inguinal disruption'. Elite athletes present quicker and return to sport sooner. Given the prevalence of other findings, a multidisciplinary approach to the 'sportsman's groin' is required.

Abstract
Introduction: Standardized outcome measures are importantfor accurately monitoring the language development of pre-lingually deaf children receiving auditory implants. Current commonly used outcome measures are time-consuming,limiting the practicality of regular testing. To address these limitations, the Manchester Spoken Language Development Scale (MSLDS) was developed as a quick and easily applicable interim measurement. This is an 11-point scale designed to provide a streamlined overview of a child's expressive language development. This study describes the MSLDS, evaluates its ease of use and inter-rater reliability, and outlines its application in the paediatric auditory implant population. Methods: Sixteen speech therapists and teachers for the deaf reviewed videos of paediatric cochlear implant assessmentsand rehabilitation sessions at a UK auditory implant centre. Twenty-five videos from fourteen children were used in this validation study. Reviewers were asked to evaluate a child's language development using the MSLDS by assigning a score for each video and to evaluate the ease of use of the scale. Each video wasrated by three different reviewers. Results: MSLDS scores showed a high degree of consistency between raters for each child. 8/25 (32%) videos demonstrated perfect agreement on the MSLDS. In 15/25 (60%) videos, there was a one-point difference between MSLDS scores. The remaining 2/25 (8%) videos varied by 2 points. Statistical analysis demonstrated an intra-class correlation coefficient (ICC) of 0.987, indicating a high level of agreement between users of the scale. Qualitative feedback from the raters suggested further modifications which have been incorporated into the scale. Conclusion: The high inter-rater agreement reflects the potential for the MSLDS to be a reliable tool for monitoring language development in the paediatric auditory implant population.

Lung clearance index in healthy volunteers, measured using a novel portable system with a closed circuit wash-in. PLoS One 2020; 15:e0229300. [PMID: 32097445 PMCID: PMC7041809 DOI: 10.1371/journal.pone.0229300] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2019] [Accepted: 02/03/2020] [Indexed: 11/18/2022] Open
Abstract
Introduction Lung clearance index (LCI) is a sensitive measure of early lung disease, but adoption into clinical practice has been slow. Challenges include the time taken to perform each test. We recently described a closed-circuit inert gas wash-in method that reduces overall testing time by decreasing the time to equilibration. The aim of this study was to define a normative range of LCI in healthy adults and children derived using this method. We were also interested in the feasibility of using this system to measure LCI in a community setting. Methods LCI was assessed in healthy volunteers at three hospital sites and in two local primary schools. Volunteers completed three washout repeats at a single visit using the closed circuit wash-in method (0.2% SF6 wash-in tracer gas to equilibrium, room air washout). Results 160 adult and paediatric subjects successfully completed LCI assessment (95%) (100 in hospital, 60 in primary schools). Median coefficient of variation was 3.4% for LCI repeats and 4.3% for FRC. Mean (SD) LCI for the analysis cohort (n = 53, age 5–39 years) was 6.10 (0.42), making the upper limit of normal LCI 6.8. There was no relationship between LCI and multiple demographic variables. Median (interquartile range) total test time was 18.7 (16.0–22.5) minutes. Conclusion The closed circuit method of LCI measurement can be successfully and reproducibly measured in healthy volunteers, including in out-of-hospital settings. Normal range appears stable up to 39 years. With few subjects older than 40 years, further work is required to define the normal limits above this age.

Abstract
Aims Remote monitoring of patients with physiological data derived from cardiac implanted electronic devices (CIEDs) offers potential to reconfigure clinical services. The ‘Heart Failure Risk Score' (HFRS) uses input from integrated device physiological monitoring to risk‐stratify patients as low‐risk, medium‐risk, or high‐risk of a heart failure event in the next 30 days. This study aimed to evaluate a novel clinical pathway utilizing a combination of CIED risk‐stratification and telephone triage to identify patients with worsening heart failure (WHF). Methods and results A prospective, single‐centre, real‐world evaluation of the ‘Triage‐HF Plus' clinical pathway (HFRS in combination with telephone triage) over a 27 month period. One hundred and fifty‐seven high‐risk HFRS transmissions were referred for telephone triage assessment. Interventions were at the discretion of the clinical assessor acting in accordance with clinical guidelines. An additional 3month consecutive sample of low and medium HFRS transmissions (control group) were also contacted for telephone triage assessment (n = 98). Successful telephone contact was made in 127 (81%) of referred high‐risk HFRS cases: 71 (55.9%) were confirmed to have WHF requiring intervention; 19 (14.9%) had an alternative acute medical problem; one patient had been recently discharged from hospital with WHF; and 36 (28.0%) had no apparent cause for the high score. In the control group, only one patient had symptoms of WHF. The sensitivity and specificity of CIED‐based remote monitoring to identify WHF 98.6% (92.5–100.0%) and 63.4% (55.2–71.0%), respectively. Conclusions The Triage‐HF Plus clinical pathway is a potentially useful remote monitoring tool for patients with heart failure and in situ CIEDs.

Abstract
Introduction Mucopolysaccharidosis (MPS) type IVA is a rare, autosomal recessive lysosomal storage disease causing substrate accumulation in various organs and tissues. MPS IVA is associated with both obstructive and restrictive airway disease, with the former often resulting in sleep disordered breathing (SDB). Respiratory failure is a primary cause of death in this condition. The aim of this study was to characterise and catalogue the long-term respiratory changes in patients with MPS IVA treated with, or without, enzyme replacement therapy (ERT). Methods In this retrospective, longitudinal, repeated-measures cohort study, descriptive statistics and non-parametric correlation were performed for demographic, respiratory function and oximetry variables over a study period from January 2009 to December 2018. Composite clinical endpoints used in this study for evaluating pulmonary function included spirometry variables (FEV1, FEV1 [%Pred] FVC, FVC [%Pred] and FEV1/FVC), oximetry variables (median %Spo2, ODI 3%, mean nadir 3%, ODI 4%, mean nadir 4% and min dip SpO2 [%]) and 6MWT to assess functional exercise capacity and thus integrated cardiopulmonary function. Results Sequential spirometry and oximetry values were collected from 16 patients, of which 13/16 were ERT treated. In general, during the study period there was a global reduction in static spirometry values in all subjects, as well as cardiorespiratory function as assessed by the 6MWT, with the decline being delayed in the ERT group. Oximetry changed to a minor degree over time in the ERT group, whereas it declined in the non-ERT group. FEV1, FVC [%predicted] and ODI 3% exhibited a strong, combined positive correlation (r 0.74–95% CI 0.61 to 0.83; p < .0001). Non-invasive ventilation (NIV) and adenotonsillectomy appeared more effective in the ERT group, either improving pulmonary function or attenuating deterioration. Conclusions Whilst spirometry values showed a gradual decline across all groups, oximetry showed modest improvement in respiratory function. The amalgamation of FEV1, FVC [%predicted] and ODI 3% appeared predictive of changes in respiratory function in this study, suggestive as being composite endpoints for monitoring disease progression as well as guiding response to ERT in MPS IVA patients.

Abstract
OBJECTIVE People with type 1 diabetes and kidney failure have an increased risk for major adverse cardiovascular events (MACE). Simultaneous pancreas and kidney transplantation (SPKT) improves survival, but the long-term risk for MACE is uncertain. RESEARCH DESIGN AND METHODS We assessed the frequency and risk factors for MACE (defined as fatal cardiovascular disease and nonfatal myocardial infarction or stroke) and related nonfatal MACE to allograft failure in SPKT recipients with type 1 diabetes who underwent transplantation between 2001 and 2015 in the U.K. In a subgroup, we related a pretransplant cardiovascular risk score to MACE. RESULTS During 5 years of follow-up, 133 of 1,699 SPKT recipients (7.8%) experienced a MACE. In covariate-adjusted models, age (hazard ratio 1.04 per year [95% CI 1.01-1.07]), prior myocardial infarction (2.6 [1.3-5.0]), stroke (2.3 [1.2-4.7]), amputation (2.0 [1.02-3.7]), donor history of hypertension (1.8 [1.05-3.2]), and waiting time (1.02 per month [1.0-1.04]) were significant predictors. Nonfatal MACE predicted subsequent allograft failure (renal 1.6 [1.06-2.6]; pancreas 1.7 [1.09-2.6]). In the subgroup, the pretransplant cardiovascular risk score predicted MACE (1.04 per 1% increment [1.02-1.06]). CONCLUSIONS We report a high rate of MACE in SPKT recipients. There are a number of variables that predict MACE, while nonfatal MACE increase the risk of subsequent allograft failure. It may be beneficial that organs from hypertensive donors are matched to recipients with lower cardiovascular risk. Pretransplant cardiovascular risk scoring may help to identify patients who would benefit from risk factor optimization or alternative transplant therapies and warrants validation nationally.

Abstract
AIMS To assess the impact of social deprivation, demographics and centre on HbA1c outcomes with continuous subcutaneous insulin infusion (CSII) in adults with Type 1 diabetes. METHODS Demographic data, postcode-derived English Index of Multiple Deprivation data and 12-month average HbA1c (mmol/mol) pre- and post-CSII were collated from three diabetes centres in the north west of England, University Hospital of South Manchester (UHSM), Salford Royal Foundation Hospital (SRFT) and Manchester Royal Infirmary (MRI). Univariable and multivariable regression models explored relationships between demographics, Index of Multiple Deprivation, centre and HbA1c outcomes. RESULTS Data were available for 693 (78%) individuals (UHSM, n = 90; SRFT, n = 112; and MRI, n = 491) of whom 59% were women. Median age at CSII start was 39 (IQR 29.5-49.0) years and median diabetes duration was 20 (11-29) years. Median Index of Multiple Deprivation was 15 193 (6313-25 727). Overall median HbA1c improved from 69 to 64 mmol/mol (8.5% to 8.0%) within the first year of CSII. In multivariable analysis, higher pre-CSII HbA1c was significantly associated with higher deprivation (P = 0.036), being female (P < 0.001), and centre (MRI; P = 0.005). Following pre-CSII HbA1c adjustment, post-CSII HbA1c or HbA1c change were not related to demographic factors and deprivation, but remained significantly related to the centre; UHSM and SRFT had larger reductions in HbA1c with CSII compared with MRI [median -7.0 (-0.6%) vs. -6.0 (-0.55%) vs. -4.5 (-0.45%) mmol/mol; P = 0.005]. CONCLUSIONS Higher pre-CSII HbA1c levels were associated with higher deprivation and being female. CSII improves HbA1c irrespective of social deprivation and demographics. Significant differences in HbA1c improvements were observed between centres. Further work is warranted to explain these differences and minimize variation in clinical outcomes with CSII.

Abstract
BACKGROUND The local anesthetic, levobupivacaine, is the safer enantiomer of racemic bupivacaine. Present protocols for levobupivacaine are based on studies and pharmacokinetic modeling with racemic bupivacaine. AIMS The aim is to investigate total serum levobupivacaine concentrations after a caudalepidural loading dose followed by a maintenance infusion over 48 hours in infants aged 3-6 months. METHODS The clinical trial was conducted in eight infants aged 3-6 months, undergoing bladder exstrophy repair. Pharmacokinetic modeling allowed optimization of clinical sampling to measure total levobupivacaine and α1 -acid glycoprotein and prediction of the effect of α1 -acid glycoprotein on levobupivacaine plasma protein binding. RESULTS The observed median total levobupivacaine serum concentration was 0.30 mg/L (range: 0.20-0.70 mg/L) at 1 hour after the loading dose of 2 mg/kg. The median total levobupivacaine concentration after 47 hours of infusion, at 0.2 mg/kg/h, was 1.21 mg/L (0.07-1.85 mg/L). Concentrations of α1 -acid glycoprotein were found to rise throughout the study period. Pharmacokinetic modeling suggested that unbound levobupivacaine quickly reached steady state at a concentration of approximately 0.03 mg/L. CONCLUSION The study allows the development of a pharmacokinetic model, combining levobupivacaine and α1 -acid glycoprotein data. Modeling indicates that unbound levobupivacaine quickly reaches steady state once the infusion is started. Simulations suggest that it may be possible to continue the infusion beyond 48 hours.

Abstract
Background There are limited reports outlining the financial cost of treating cardiac implantable electronic device (CIED) infection outside the United States. This study aimed to determine the average treatment cost of CIED infection in a large UK tertiary referral centre and compared costs of different treatment pathways that are recognised in the management of CIED infection (early versus delayed re-implantation). Methods We retrospectively analysed cost and length of stay (LOS) data for consecutive patients undergoing infected CIED extraction with cardiac resynchronization therapy (CRT-D [with defibrillator], CRT-P [with pacemaker]), implantable cardioverter-defibrillators (ICDs) and permanent pacemakers (PPMs). Results Between January 2013 and March 2015, complete data was available for 84 patients (18 [21.4%] CRT-D, 24 [28.6%] ICDs and 42 [50.0%] PPMs). When all cases were considered the cost of infection ranged from £5,139 (PPM) to £24,318 (CRT-D). Considering different treatment strategies; 41 (48.8%) underwent CIED extraction and re-implantation during the same admission (early re-implant strategy (ER). 43 (51.2%) underwent extraction, but were then discharged home to be re-admitted for day-case re-implantation (delayed re-implant strategy (DR)). Median LOS was significantly shorter in DR compared to ER (5.0 vs. 18.0 days, p<0.001). The total cost of CIED infection episode was similar for both treatment strategies (median £14,241.48 vs. £14,741.70 including wearable defibrillator (Lifevest) and outpatient antibiotics costs, ER vs. DR; p = 0.491). Conclusion CIED infections are expensive and associated with significant health-economic burden. When all device types were considered, a DR strategy is associated with reduced LOS without an increased cost penalty.

A Randomized Study Comparing the Incidence of Postoperative Pain After Phrenic Nerve Infiltration Vs Nonphrenic Nerve Infiltration During Thoracotomy. Semin Thorac Cardiovasc Surg 2018; 31:583-592. [PMID: 30529157 DOI: 10.1053/j.semtcvs.2018.11.014] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2018] [Accepted: 11/30/2018] [Indexed: 11/11/2022]
Abstract
Thoracotomy is a common surgical procedure performed worldwide for lung disease. Despite major advances in analgesia, patients still experience severe shoulder, central back and surgical incision site pain in the postoperative period. This study aimed to assess whether intraoperative phrenic nerve infiltration reduces the incidence of postoperative pain and improves peak flow volume measurements during incentive spirometry. 90 patients undergoing open lobectomy were randomly assigned to have phrenic nerve infiltration (n = 46) or not (n = 44). The phrenic nerve infiltration group received 10 mL of 0.25% bupivacaine into the periphrenic fat pad. Preoperative assessments of spirometry and pain scores were recorded (at rest and with movement). Postoperative assessments included peak flow and pain measurements at intervals up to 72 hours. Less shoulder pain was experienced with phrenic nerve infiltration up to 6 hours postsurgery at rest (P = 0.005) and up to 12 hours with movement (P < 0.001). Reduced back pain was reported in the phrenic nerve infiltration group up to 6 hours after surgery both at rest (P = 0.001) and with movement (P = 0.00). Phrenic nerve infiltration reduced pain at the incision site for up to 3 hours both at rest (P < 0.001) and with movement (P = 0.001). Spirometry readings dropped in both groups with consistently lower readings at baseline and follow-up in the PNI group (P = 0.007). Lower analgesic usage of patient controlled analgesia morphine (P < 0.0001), epipleural bupivacaine (P = 0.001), and oramorph/zomorph (P = 0.0002) were recorded. Our findings indicate that the use of phrenic nerve infiltration significantly reduced patient pain scores during the early postoperative period, particularly during movement. We believe that each technique has advantages and disadvantages; however, further studies with large sample size are warranted.

One-Month Global Longitudinal Strain Identifies Patients Who Will Develop Pacing-Induced Left Ventricular Dysfunction over Time: The Pacing and Ventricular Dysfunction (PAVD) Study. PLoS One 2017; 12:e0162072. [PMID: 28095413 PMCID: PMC5240943 DOI: 10.1371/journal.pone.0162072] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2016] [Accepted: 08/17/2016] [Indexed: 11/25/2022] Open
Abstract
Background Predicting which individuals will have a decline in left ventricular (LV) function after pacemaker implantation remains an important challenge. We investigated whether LV global longitudinal strain (GLS), measured by 2D speckle tracking strain echocardiography, can identify patients at risk of pacing-induced left ventricular dysfunction (PIVD) or pacing-induced cardiomyopathy (PICMP). Methods Fifty-five patients with atrioventricular block and preserved LV function underwent dual-chamber pacemaker implantation and were followed with serial transthoracic echocardiography for 12 months for the development of PIVD (defined as a reduction in LV ejection fraction (LVEF) ≥5 percentage points at 12 months) or PICMP (reduction in LVEF to <45%). Results At 12 months, 15 (27%) patients developed PIVD; of these, 4 patients developed PICMP. At one month, GLS was significantly lower in the 15 patients who subsequently developed PIVD, compared to those who did not (n = 40) (GLS -12.6 vs. -16.4 respectively; p = 0.022). When patients with PICMP were excluded, one month GLS was significantly reduced compared to baseline whereas LVEF was not. One-month GLS had high predictive accuracy for determining subsequent development of PIVD or PICMP (AUC = 0.80, optimal GLS threshold: <−14.5, sensitivity 82%, specificity 75%); and particularly PICMP (AUC = 0.86, optimal GLS threshold: <−13.5, sensitivity 100%, specificity 71%). Conclusions GLS is a novel predictor of decline in LV systolic function following pacemaker implantation, with the potential to identify patients at risk of PIVD before measurable changes in LVEF are apparent. GLS measured one month after implantation has high predictive accuracy for identifying patients who later develop PIVD or PICMP.

Abstract
AIMS To ascertain any predictors of potential food poisoning pathogens and development of post-infective irritable bowel syndrome (IBS) in UK travellers. An analysis was undertaken on prospectively collected data on 527 patients reporting symptoms of suspected food poisoning between June 2012 and June 2015. MAIN OUTCOME MEASURES Positive stool sample indicative of food poisoning pathogens and diagnosis of post-infective IBS. RESULTS Data on 527 patients were examined. The large majority of patients did not provide a stool sample on return from holiday (n = 430, 81.6%) as few visited a Doctor locally or in the UK. Only 18 patients (18.6%, 95% confidence interval [CI] 11.4-27.7) who provided a stool sample were positive for microbiological food poisoning pathogens. Univariate analysis indicated a significant relationship between a positive stool sample and whether the individual sought any medical assistance at the resort (odds ratio [OR] 0.24, 95% CI 0.08-0.70) and whether they took any treatment (including self-medicated), (OR 0.21, 95% CI 0.06-0.67). Of the 527 patients only 30 (5.7%, 95% CI 3.9-8.1) experienced post-infective IBS. Univariate regression indicated a significant relationship between experiencing Per Rectal (PR) bleeding and a diagnosis of post-infective IBS (OR 3.64, 95% CI 1.00-10.49). Univariate regression also indicated an increase in the risk of developing post-infective IBS with increasing duration of symptoms (OR 1.04, 95% CI 1.02-1.05). No significant relationship was found between a positive stool sample and developing post-infective IBS (P = 0.307). CONCLUSIONS Very few patients provide a stool sample after experiencing holiday sickness abroad. Of those that do, only a small proportion have a positive stool sample indicative of a food poisoning microorganism. Around 6% of individuals were diagnosed with post-infective IBS. Those individuals with PR bleeding and symptoms persisting for longer durations were significantly more at risk of developing post-infective IBS, whilst medical aid and treatment abroad was found to reduce the odds of a positive stool sample.

Abstract
BackgroundEffective paediatric basic life support improves survival and outcomes. Current cardiopulmonary resuscitation (CPR) training involves 4-yearly courses plus annual updates. Skills degrade by 3–6 months. No method has been described to motivate frequent and persistent CPR practice. To achieve this, we explored the use of competition and a leaderboard, as a gamification technique, on a CPR training feedback device, to increase CPR usage and performance.ObjectiveTo assess whether self-motivated CPR training with integrated CPR feedback improves quality of infant CPR over time, in comparison to no refresher CPR training.DesignRandomised controlled trial (RCT) to assess the effect of self-motivated manikin-based learning on infant CPR skills over time.SettingA UK tertiary children's hospital.Participants171 healthcare professionals randomly assigned to self-motivated CPR training (n=90) or no refresher CPR training (n=81) and followed for 26 weeks.InterventionThe intervention comprised 24 h a day access to a CPR training feedback device and anonymous leaderboard. The CPR training feedback device calculated a compression score based on rate, depth, hand position and release and a ventilation score derived from rate and volume.Main outcome measureThe outcome measure was Infant CPR technical skill performance score as defined by the mean of the cardiac compressions and ventilations scores, provided by the CPR training feedback device software. The primary analysis considered change in score from baseline to 6 months.ResultsOverall, the control group showed little change in their scores (median 0, IQR −7.00–5.00) from baseline to 6 months, while the intervention group had a slight median increase of 0.50, IQR 0.00–33.50. The two groups were highly significantly different in their changes (p<0.001).ConclusionsA significant effect on CPR performance was demonstrated by access to self-motivated refresher CPR training, a competitive leaderboard and a CPR training feedback device.

Abstract
INTRODUCTION Bladder Exstrophy and Epispadias Complex (BEEC) is associated with an increased risk of impaired mental health, quality of life, and psychosocial functioning. Therefore, screening patients to help identify and evaluate potential psychosocial difficulty is arguably an important consideration for BEEC Services. OBJECTIVE To screen paediatric BEEC patients for a range of general psychosocial difficulties in a multi-disciplinary out-patient clinic setting. STUDY DESIGN This cross-sectional evaluation was conducted between April 2012 and July 2013. Families attending BEEC multi-disciplinary out-patient clinics were asked to complete a range of standardised psychosocial questionnaires, including the Paediatric Quality of Life Inventory (PedsQL 4.0 Generic Core and Family Impact Module), the Strengths and Difficulties Questionnaire (SDQ), the Paediatric Index of Emotional Distress (PI-ED), and the Hospital Anxiety and Depression Scale (HADS). 108 children attended clinic of which 80 (74.1%) patients and their parents/carers completed some or all of the questionnaires. The mean patient age was 8.41 years (SD = 4.46, range = 1-18 years). There were more boys (N = 50, 62.5%) and the majority had a diagnosis of classic bladder exstrophy (N = 51, 63.8%), followed by primary epispadias (N = 22, 27.5%) and cloacal exstrophy (N = 7, 8.7%). RESULTS Mean total scores fell within the average/normal range on all questionnaires used (See table below). However, variation around these means was high. Age, gender and diagnosis were found to significantly influence certain questionnaire responses with older-age groups, males, and those with classic bladder exstrophy particularly at risk across some domains. The children/adolescents self-reported better health related quality of life (HRQoL) scores than published results for a range of paediatric chronic health conditions. Differences between parent and child responses on both the PedsQL and SDQ favoured a more positive response on the child self-report questionnaire but were not statistically significant. DISCUSSION Mean scores on the measures used suggest a relatively optimistic picture of general psychosocial well-being, especially for HRQoL, in the BEEC population studied. Positive HRQoL outcomes have recently been reported for BEEC paediatric populations. Our results reflect this trend with better mean HRQoL scores than paediatric patients with a range of other chronic health conditions. However, this optimism is cautious given the limitations of this evaluation study and the high variation around the means. Limitations included the small sample size (especially for patients with cloacal exstrophy), the lack of a control group, the limited sensitivity of generic questionnaires in respect of BEEC-specific issues, and the low mean age of patients in the study. Future screening programmes may wish to consider measuring BEEC-specific variables (e.g. satisfaction with genital appearance/function); collecting information on medical aspects, such as continence, pubertal stage and frequency/timing of medical intervention; and asking both parents/carers (where possible) to complete the questionnaires. CONCLUSIONS Screening questionnaire responses were used in conjunction with clinical psychology consultations to evaluate a range of psychosocial aspects in BEEC paediatric patients. Whilst mean scores on the measures used suggest a relatively optimistic picture, certain individual scores did fall within the clinical ranges, highlighting the potential need for further assessment. Developmentally tailored consultations with a clinical psychologist can provide detailed information around questionnaire responses and further assess BEEC specific aspects.

Abstract
AIMS To examine the utility of (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) in the early diagnosis of cardiac implantable electronic device (CIED) generator pocket infection. METHODS AND RESULTS A total of 86 patients with CIEDs were evaluated with (18)F-FDG PET/CT imaging: 46 with suspected generator pocket infection and 40 without any history of infection. (18)F-FDG activity in the region of the generator pocket was expressed as a semi-quantitative ratio (SQR)-defined as the maximum count rate around the CIED divided by the mean count rate between normal right and left lung parenchyma. All patients underwent standard clinical management, independent of the PET/CT result. Patients with suspected generator pocket infection that required CIED extraction (n = 32) had significantly higher (18)F-FDG activity compared with those that did not (n = 14), and compared with controls (n = 40) [SQR: 4.80 (3.18-7.05) vs. 1.40 (0.88-1.73) vs. 1.10 (0.98-1.40), respectively; P < 0.001]. On receiver operator characteristic analysis, SQR had a high diagnostic accuracy (area under curve = 0.98) for the early identification of patients with confirmed infection (i.e. those ultimately needing extraction)-with an optimal SQR cut-off value of >2.0 (sensitivity = 97%; specificity = 98%). CONCLUSION This study highlights the potential benefits of evaluating patients with suspected CIED generator pocket infection using (18)F-FDG PET/CT. In this study, (18)F-FDG PET/CT had a high diagnostic accuracy in the early diagnosis of CIED generator pocket infection, even where initial clinical signs were underwhelming.

Abstract
BACKGROUND AKI is common among hospital in-patients and places a huge financial burden on the UK National Health Service, causing increased length of hospital stay and use of critical care services, with increased requirement for complex interventions including dialysis. This may account for up to 0.6% of the total Health Service budget. To investigate the incidence and consequences of AKI, all unselected emergency admissions to a large acute UK single centre University Teaching Hospital over two separate 7 day periods were reviewed. METHODS A retrospective audit of 745 case records was undertaken (54.6% male) including laboratory data post-discharge or death, with classification of AKI by RIFLE, AKIN and AKIB criteria. Participants were included whether admitted via their general practitioners, the emergency department, or as tertiary specialty transfers. Outcome measures were presence or absence of AKI recorded using each of the three AKI criteria, length of hospital stay (LOS), admission to, and LOS in critical care, and mortality. The most severe grade of AKI only, at any time during the admission, was recorded to prevent double counting. Renal outcome was determined by requirement for renal replacement therapy (RRT), and whether those receiving RRT remained dialysis dependent or not. RESULTS AKI incidence was 25.4% overall. With approximately one third present on admission and two thirds developing post admission. The AKI group had LOS almost three times higher than the non AKI group (10 vs 4 days). Requirement for critical care beds was 8.1% in the AKI group compared to 1.7% in non AKI group. Overall mortality was 5.5%, with the AKI group at 11.4% versus 3.3% in the non AKI group. CONCLUSIONS AKI in acute unselected hospital admissions is more common than existing literature suggests, affecting 25% of unselected admissions. In many this is relatively mild and may resolve spontaneously, but is associated with increased LOS, likelihood of admission to critical care, and risk of death. If targeted effective interventions can be developed it seems likely that substantial clinical benefits for the patient, as well as financial and structural benefits for the healthcare organisation may accrue.
