[PMID: 38484557 DOI: 10.1016/j.amjoto.2024.104228] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Revised: 02/14/2024] [Accepted: 02/19/2024] [Indexed: 05/07/2024]
Abstract
OBJECTIVE Dysphagia is multifactorial in unilateral vocal fold immobility (UVFI). Severe dysphagia could indicate greater functional deficits in UVFI. The purpose of this study is to evaluate the association of dysphagia with the need for surgical voice restoration in patients with UVFI. STUDY DESIGN Retrospective chart review. SETTING Single-institution, tertiary referral center. METHODS Records of UVFI patients from 2008 to 2018 were examined. Dysphagia severity was extracted from patient history. Etiology of UVFI and other relevant variables were analyzed to determine their association with dysphagia. Dysphagia severity and other clinical variables were then analyzed for their association with surgical voice restoration. RESULTS Eighty patients met selection criteria out of 478 patients with UVFI. There was significant concordance between dysphagia severity extracted from patient history and patient-reported EAT-10 scores (R = 0.59, p = 0.000035). Patients' EAT-10 scores were correlated with VHI-10 scores (R = 0.45, p = 0.011). Severe dysphagia (p = 0.037), high VHI-10 score on presentation (p = 0.0009), and longer duration of hoarseness before presentation (p = 0.008) were associated with surgical voice restoration in UVFI patients. CONCLUSION In this pilot study, severe dysphagia and increased voice handicap on presentation were associated with the need for surgical voice restoration in UVFI patients. Presenting dysphagia may be an additional variable for clinicians to consider for management of UVFI.

Abstract
BACKGROUND A 48-year-old patient presented 4 months after insertion of a right sided Haemodialysis with Reliable Outflow (HeRO®, Merit Medical) graft with a discharging abscess at the site of the brachial artery anastomosis. There was localised involvement of the arterial Gore® Acuseal inflow graft that necessitated its removal. The venous outflow component was thought salvageable as infection was well localised to the region of the antecubital fossa. OBJECTIVES Alternative access options were limited so we sought to preserve the venous outflow portion of the patient's original graft - minimising tissue damage and avoiding the need for a dialysis line. METHODS The infected arterial graft was excised, leaving behind the original SuperHero® connector and venous graft. A left sided tunnelled axillary necklace technique was utilised to restore arterial inflow. RESULTS After a four-day recovery, the patient went on to successfully resume their usual haemodialysis regimen without any complications. Convalescent imaging, repeat blood cultures, and monitoring of inflammatory markers showed no signs of residual infection at 6 weeks. CONCLUSIONS The originality of this case was the way in which an axillary necklace inflow graft was connected to the pre-existing venous outflow portion of the HeRO® haemodialysis graft system, allowing the excision of the infected inflow graft at the brachial anastomosis. This technique could be viewed as an effective salvage procedure as it allowed the venous outflow portion of the original graft to remain in situ, minimised tissue damage and enabled the patient to swiftly resume haemodialysis without the need for a line.

Abstract
Data collection, analysis, and reporting are fundamental for a successful hospital-based patient blood management program; however, very little has been published on the topic. Our aim was to synthesize evidence from a literature review to provide a detailed, practical list of outcome metrics, and the required data collection(s) to inform implementation. Ovid MEDLINE and PubMed were searched for any full-text original research articles published from inception to the year 2020. We included any studies reporting the implementation of interventions or programs study authors defined as "patient blood management" and extracted information on data collected and metrics reported. We included 45 studies describing the implementation of a patient blood management program and/or strategies. The outcomes reported by these studies were grouped into 1 of 36 metrics. We compiled a list of 65 relevant data elements to collect, and their potential source hospital information systems: patient administration, laboratory, transfusion/blood bank, operating room, pharmacy, emergency department, and intensive care unit. We further categorized patient blood management data systems into basic, intermediate, and advanced based on the combination of different information systems sourced. The results of this review can be used to inform patient blood management programs in planning what data collection(s) are needed, where these data can be sourced from, and how they can be analyzed.

Model-informed approach to support pediatric dosing for the pan-PI3K inhibitor copanlisib in children and adolescents with relapsed/refractory solid tumors. Clin Transl Sci 2023; 16:1197-1209. [PMID: 37042099 PMCID: PMC10339701 DOI: 10.1111/cts.13523] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2023] [Revised: 02/21/2023] [Accepted: 03/17/2023] [Indexed: 04/13/2023] Open
Abstract
Copanlisib is an intravenously administered phosphatidylinositol 3-kinase (PI3K) inhibitor which was investigated in pediatric patients with relapsed/refractory solid tumors. A model-informed approach was undertaken to support and confirm an empirically selected starting dose of 28 mg/m2 for pediatric patients ≥1 year old, corresponding to 80% of the adult recommended dose adjusted for body surface area. An adult physiologically based pharmacokinetic (PBPK) model was initially established using copanlisib physicochemical and disposition properties and clinical pharmacokinetics (PK) data and was shown to adequately capture clinical PK across a range of copanlisib doses in adult cancer patients. The adult PBPK model was then extended to the pediatric population through incorporation of age-dependent anatomical and physiological changes and used to simulate copanlisib exposures in pediatric cancer patient age groups. The pediatric PBPK model predicted that the copanlisib 28 mg/m2 dose would achieve similar copanlisib exposures across pediatric ages when compared with historical adult exposures following the approved copanlisib 60 mg dose administered on Days 1, 8, and 15 of a 28-day cycle. Clinical PK were collected from a phase I study in pediatric patients with relapsed/refractory solid tumors (aged ≥4 years). An established adult population PK model was extended to incorporate an allometrically-scaled effect of body surface area and confirmed that the copanlisib maximum tolerated dose of 28 mg/m2 was appropriate to achieve uniform copanlisib exposures across the investigated pediatric age range and consistent exposures to historical data in adult cancer patients. The model-informed approach successfully supported and confirmed the copanlisib pediatric dose recommendation.

Medial patellofemoral ligament reconstruction and tibial tuberosity transfer can be used to successfully manage patellofemoral instability in the setting of trochlea dysplasia. Knee Surg Relat Res 2023; 35:11. [PMID: 37106401 PMCID: PMC10141911 DOI: 10.1186/s43019-023-00181-7] [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: 06/05/2022] [Accepted: 02/28/2023] [Indexed: 04/29/2023] Open
Abstract
BACKGROUND Management of patella instability remains a challenge particularly in the presence of trochlea dysplasia. The aim of this study is to assess the recurrence rates of those with patellar instability who have undergone a combined tibial tuberosity transfer (TTT) and medial patellofemoral ligament reconstruction (MPFLR) in the setting of trochlea dysplasia. METHODS All skeletally mature patients who underwent combined TTT and MPFLR for recurrent patella instability were identified between January 2009 and December 2019. A retrospective review was conducted, with information regarding re-dislocation/subluxation and complications collected. RESULTS Seventy patients with a mean age 25.3 years were identified and evaluated. Thirteen patients were found to have low-grade dysplasia (Dejour A), with 57 patients having high-grade dysplasia (Dejour B/C/D). No patients in the low,grade dysplasia group suffered a recurrence of their symptoms, with four in the high-grade group suffering episodes of re-dislocation/subluxation. Three patients subsequently underwent a trochleoplasty, with the other patient managed successfully non-operatively. There were a total of 13 complications in 11 patients. CONCLUSIONS A combined procedure of MPFLR and TTT can be used to manage patellofemoral instability even in the setting of trochlea dysplasia with a low rate of recurrence. Trochlea dysplasia, however, remains an anatomical risk factor for recurrence and patients should be counselled accordingly. The anatomical risk factors should be assessed in all patients to allow for the development of the most appropriate management plan, of which this combined procedure represents a potentially successful option. LEVEL OF EVIDENCE IV (Case Series).

Abstract
Abstract
We describe a rare congenital portosystemic shunt. A 37-year-old woman was found to have a previously unreported congenital shunt following investigations into secondary causes of hypertension. The abnormal venous shunt connected the splenic vein to the left ovarian vein. The patient underwent a laparoscopic procedure to successfully divide the shunt. She made a full recovery without complications. To our knowledge, this is the first presentation of a congenital portosystemic shunt involving the splenic and ovarian veins to be reported. This case demonstrates that such a shunt can be amenable for laparoscopic management. The case report shows preoperative scans and intraoperative images.

Clinical characteristics with inflammation profiling of long COVID and association with 1-year recovery following hospitalisation in the UK: a prospective observational study. THE LANCET. RESPIRATORY MEDICINE 2022; 10:761-775. [PMID: 35472304 PMCID: PMC9034855 DOI: 10.1016/s2213-2600(22)00127-8] [Citation(s) in RCA: 144] [Impact Index Per Article: 72.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/04/2022] [Revised: 03/23/2022] [Accepted: 03/31/2022] [Indexed: 11/25/2022]
Abstract
BACKGROUND No effective pharmacological or non-pharmacological interventions exist for patients with long COVID. We aimed to describe recovery 1 year after hospital discharge for COVID-19, identify factors associated with patient-perceived recovery, and identify potential therapeutic targets by describing the underlying inflammatory profiles of the previously described recovery clusters at 5 months after hospital discharge. METHODS The Post-hospitalisation COVID-19 study (PHOSP-COVID) is a prospective, longitudinal cohort study recruiting adults (aged ≥18 years) discharged from hospital with COVID-19 across the UK. Recovery was assessed using patient-reported outcome measures, physical performance, and organ function at 5 months and 1 year after hospital discharge, and stratified by both patient-perceived recovery and recovery cluster. Hierarchical logistic regression modelling was performed for patient-perceived recovery at 1 year. Cluster analysis was done using the clustering large applications k-medoids approach using clinical outcomes at 5 months. Inflammatory protein profiling was analysed from plasma at the 5-month visit. This study is registered on the ISRCTN Registry, ISRCTN10980107, and recruitment is ongoing. FINDINGS 2320 participants discharged from hospital between March 7, 2020, and April 18, 2021, were assessed at 5 months after discharge and 807 (32·7%) participants completed both the 5-month and 1-year visits. 279 (35·6%) of these 807 patients were women and 505 (64·4%) were men, with a mean age of 58·7 (SD 12·5) years, and 224 (27·8%) had received invasive mechanical ventilation (WHO class 7-9). The proportion of patients reporting full recovery was unchanged between 5 months (501 [25·5%] of 1965) and 1 year (232 [28·9%] of 804). Factors associated with being less likely to report full recovery at 1 year were female sex (odds ratio 0·68 [95% CI 0·46-0·99]), obesity (0·50 [0·34-0·74]) and invasive mechanical ventilation (0·42 [0·23-0·76]). Cluster analysis (n=1636) corroborated the previously reported four clusters: very severe, severe, moderate with cognitive impairment, and mild, relating to the severity of physical health, mental health, and cognitive impairment at 5 months. We found increased inflammatory mediators of tissue damage and repair in both the very severe and the moderate with cognitive impairment clusters compared with the mild cluster, including IL-6 concentration, which was increased in both comparisons (n=626 participants). We found a substantial deficit in median EQ-5D-5L utility index from before COVID-19 (retrospective assessment; 0·88 [IQR 0·74-1·00]), at 5 months (0·74 [0·64-0·88]) to 1 year (0·75 [0·62-0·88]), with minimal improvements across all outcome measures at 1 year after discharge in the whole cohort and within each of the four clusters. INTERPRETATION The sequelae of a hospital admission with COVID-19 were substantial 1 year after discharge across a range of health domains, with the minority in our cohort feeling fully recovered. Patient-perceived health-related quality of life was reduced at 1 year compared with before hospital admission. Systematic inflammation and obesity are potential treatable traits that warrant further investigation in clinical trials.

Abstract
OBJECTIVES The ability to predict in-hospital mortality from data available at hospital admission would identify patients at risk and thereby assist hospital-wide patient safety initiatives. Our aim was to use modern machine learning tools to predict in-hospital mortality from standardized data sets available at hospital admission. METHODS This was a retrospective, observational study in 3 adult tertiary care hospitals in Western Australia between January 2008 and June 2017. Primary outcome measures were the area under the curve for the receiver operating characteristics curve, the F1 score, and the average precision of the 4 machine learning algorithms used: logistic regression, neural networks, random forests, and gradient boosting trees. RESULTS Using our 4 predictive models, in-hospital mortality could be predicted satisfactorily (areas under the curve for neural networks, logistic regression, random forests, and gradient boosting trees: 0.932, 0.936, 0.935, and 0.935, respectively), with moderate F1 scores: 0.378, 0.367, 0.380, and 0.380, respectively. Average precision values were 0.312, 0.321, 0.334, and 0.323, respectively. It remains unknown whether additional features might improve our models; however, this would result in additional efforts for data acquisition in daily clinical practice. CONCLUSIONS This study demonstrates that using only a limited, standardized data set in-hospital mortality can be predicted satisfactorily at the time point of hospital admission. More parameters describing patient's health are likely needed to improve our model.

Abstract
INTRODUCTION Virtual reality (VR) fully immersive interactive video teaching (VR FIIT) allows learners to develop through observing and interacting with complex realistic environments, developing technical and nontechnical skills. One such complex clinical environment is managing a trauma patient. Despite the significant developments in managing these patients, foundation doctors are frequently highly anxious due to their limited knowledge and experience. The aim of this project was twofold; to improve foundation doctor performance of managing trauma patients and to reduce their associated anxiety, through the use of VR teaching. METHODS A total of 14 foundation doctors were divided into two groups. One group underwent departmental teaching. The second group underwent departmental teaching and VR FIIT. We assessed the doctors via two methods. First, time taken to complete tasks correctly in trauma simulations was compared. Second, the doctors completed a self-reported level-based assessment questionnaire regarding anxiety and stress around trauma calls. RESULTS The VR FIIT intervention group were able to complete each task on average 118s faster than the standard group. The standard group missed essential tasks such as C-spine immobilisation. The VR FIIT group self-reported significantly lower levels of anxiety related to trauma calls. CONCLUSION VR teaching improves foundation doctor performance at managing simulated major trauma patients and decreases foundation doctor anxiety towards management and exposure of these clinical situations.

Abstract
BackgroundClinical communication plays a key role in conveying compassion between individuals. Positive non-verbal communication (NVC) has been shown to encourage connectedness and improve patient outcomes – i.e. reducing pain and anxiety – in a range of conditions, including major trauma. Whilst little is understood about how staff utilise NVC in the resuscitation room, quality of interpersonal interactions has been shown to be the largest overall predictor of patient satisfaction within the Emergency Department (ED). Existing studies within the ED highlight patient experiences of feeling ‘isolated’, with their distress being ‘insensitively disregarded’ by staff, hence further research is required to improve patient experience.MethodsThis study utilised the video auditing system within the ED of Edinburgh’s Royal Infirmary to observe how emergency staff employed NVC with conscious patients across (n=15) resuscitation cases. Results were fed back to clinical staff, with suggestions for developing compassion awareness. Mixed method qualitative and quantitative analyses were employed to assess positive and negative staff NVC behaviours and evaluate how these appeared to influence patient experience. Several existing matrices for measuring staff non-technical performance informed design of a novel system for scoring five key aspects of clinical NVC: touch, eye contact, body language, proximity and patient exposure.ResultsThis study highlights significant variation in how emergency staff convey compassion to patients during resuscitation. Staff members exhibited a range of positive and negative NVC behaviours, which were occasionally at odds with verbal cues given. Patterns of communication appeared related to members’ roles within the emergency team, with medical and nursing staff exhibiting different strengths.ConclusionsOur findings are consistent with the idea that acts of compassion are ‘emotional labour’, underlining the need for staff education surrounding positive NVC, as well as increased workplace support. We suggest environmental level strategies including incorporation of a specifically designed ‘compassionate care’ toolkit into handover/pre-arrival checklists.

Abstract
Abstract
Objective
Management of poor response and of long-term complications after bariatric surgery (BS) is complex and under-investigated. Indications and types of reoperations vary widely and postoperative complication rates are higher compared to primary BS. Benchmarking uses best performance in a given field as reference point for improvement. Our aim was to define ‘‘best possible’’ outcomes for elective secondary BS.
Methods
The establishment of benchmarks in secondary BS followed a standardized methodology, based on recommendations of a Delphi consensus panel of experts. This multicenter study analyzed patients undergoing elective secondary BS in 18 high-volume centers on 4 continents from 06/2013 to 05/2019. Twenty-one outcome benchmarks were established in low-risk patients, defined as the 75th percentile of the median outcome values of the centers. Benchmark cases had no: previous laparotomy, diabetes, sleep apnea, cardiopathy, renal insufficiency, inflammatory bowel disease, immunosuppression, history of thromboembolic events, BMI>50kg/m2 or age>65 years. Descriptive statistics, multivariate logistic regression and data visualization were performed using the R software.
Results
Out of 44’884 elective bariatric procedures performed in the participating centers, 5’328 secondary BS cases were identified. The benchmark cohort included 3143 cases, mainly females (85%), aged 43.8±10 years, 8.4±5.3 years after primary BS, with a body mass index 35.2±7kg/m2. Main indications were insufficient weight loss (43%) and gastro-esophageal reflux disease/dysphagia (25%). 90-days postoperatively, 14.57% of benchmark patients presented ≥1 complication, mortality was 0.06% (n = 2). Significantly higher morbidity was observed in non-benchmark cases (OR 1.36) and after conversional or revisional procedures with gastrointestinal suture/stapling (OR 1.7). Benchmark cutoffs at 90-days postoperatively were ≤5.8% re-intervention and ≤8.8% re-operation rate. At 2-years (IQR 1-3) 15.6% of benchmark patients required a reoperation.
Conclusion
Secondary BS is safe, although postoperative morbidity exceeds the established benchmarks for primary BS. The excess morbidity is due to an increased risk of gastrointestinal leakage and higher need for intensive care. The considerable rate of tertiary BS warrants expertise and future research to optimize the management of non-success after BS.

Abstract
Abstract
Background
Tumour budding (TB) is an adverse histological feature in many cancers. It is thought to represent epithelial-to-mesenchymal transition, a key step in the metastatic process. The role of TB in breast carcinoma (BC) remains unclear.
Aim
To investigate the relationship between TB and other histological and molecular features of BC.
Method
A systematic search was performed to identify studies that compared features of BC based on the presence or absence of high-grade TB. Dichotomous variables were pooled as odds ratios (OR) using the Cochran–Mantel–Haenszel method. Quality assessment of the included studies was performed using the Newcastle-Ottawa scale (NOS).
Result
Seven studies with a total of 1040 patients (high grade TB n=519, 49.9%; low grade TB n=521, 50.1%) were included. A moderate- to high-risk of bias was noted. The median NOS was 7 (range 6-8). High-grade TB was significantly associated with lymph node involvement (OR 2.28, 95% c.i. 1.74 to 2.98, P<0.001) and lymphovascular invasion (OR 3.08, 95% c.i. 2.13 to 4.47, P<0.001). Regarding molecular subtypes, there was an increased likelihood of high-grade TB in oestrogen- (OR 1.66, 95% c.i. 1.21 to 2.29, P=0.002) and progesterone-receptor positive (OR 1.68, 95% c.i. 1.10 to 2.59, P=0.02) tumours. In contrast triple negative breast cancer had a reduced incidence of high-grade TB (OR 0.46, 95% c.i. 0.30 to 0.72, P=0.0006).
Conclusion
High-grade TB is enriched in hormone-positive BC and is associated with known adverse prognostic variables. TB may offer new insights into the metastatic processes of luminal BC.
Take-home message
High-grade TB is enriched in hormone-positive BC and is associated with known adverse prognostic variables. TB may offer new insights into the metastatic processes of luminal BC.

Introduction
Population ageing is a triumph of public health and medical advancement but it can equally lead to burdensome and futile interventions at the end of natural life. This is especially relevant when offering treatments such as cardiopulmonary resuscitation (CPR) that can carry a significant burden of harm. The aim of this study was to investigate the association between increasing frailty and greater co-morbidity and surviving CPR.
Method
A retrospective analysis of prospectively collected data from contemporaneous patient notes and electronic patient records of all patients that suffered an in-hospital cardiac arrest between 1st April 2017 and March 31st 2018 in a tertiary hospital (that includes tertiary cardiology) in South Wales was undertaken.
Results
A total of 113 patient records were assessed. Average patient age was 74. Patient frailty was assessed based on calculation of Rockwood score (RS) and co-morbidity assessment based on Charlson index (CI). We identified a strong linear correlation between increasing CI and poor survival and rates of ROSC. No patient with a Charlson index of above 6 survived one year. Similarly, patients with a RS between 1–3 had a survival to discharge, 30 day and 1 year survival rate of 45.7%. Only 10.3% of those with a RS between 5–9 survived 1 year post cardiac arrest. No patient with a RS above 6 survived one year. No association between duration of CPR and patient frailty was identified. Increasing age was also found to be linearly associated with reduced likelihood of survival. This association was much less significant than the association with increasing RS or CI.
Conclusion
It is clear from our findings that both increasing patient frailty and level of co-morbidity significantly adversely affect survival from CPR. Accurate individualised assessment of both of these factors is therefore imperative when assessing the appropriateness of undertaking CPR.

Machine learning-based prediction of transfusion. Transfusion 2020; 60:1977-1986. [PMID: 32596877 PMCID: PMC7540018 DOI: 10.1111/trf.15935] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2019] [Revised: 05/10/2020] [Accepted: 05/15/2020] [Indexed: 12/15/2022]
Abstract
Background The ability to predict transfusions arising during hospital admission might enable economized blood supply management and might furthermore increase patient safety by ensuring a sufficient stock of red blood cells (RBCs) for a specific patient. We therefore investigated the precision of four different machine learning–based prediction algorithms to predict transfusion, massive transfusion, and the number of transfusions in patients admitted to a hospital. Study Design and Methods This was a retrospective, observational study in three adult tertiary care hospitals in Western Australia between January 2008 and June 2017. Primary outcome measures for the classification tasks were the area under the curve for the receiver operating characteristics curve, the F1 score, and the average precision of the four machine learning algorithms used: neural networks (NNs), logistic regression (LR), random forests (RFs), and gradient boosting (GB) trees. Results Using our four predictive models, transfusion of at least 1 unit of RBCs could be predicted rather accurately (sensitivity for NN, LR, RF, and GB: 0.898, 0.894, 0.584, and 0.872, respectively; specificity: 0.958, 0.966, 0.964, 0.965). Using the four methods for prediction of massive transfusion was less successful (sensitivity for NN, LR, RF, and GB: 0.780, 0.721, 0.002, and 0.797, respectively; specificity: 0.994, 0.995, 0.993, 0.995). As a consequence, prediction of the total number of packed RBCs transfused was also rather inaccurate. Conclusion This study demonstrates that the necessity for intrahospital transfusion can be forecasted reliably, however the amount of RBC units transfused during a hospital stay is more difficult to predict.

Effective diabetes complication management is a step toward a carbon-efficient planet: an economic modeling study. BMJ Open Diabetes Res Care 2020; 8:8/1/e001017. [PMID: 32299897 PMCID: PMC7199151 DOI: 10.1136/bmjdrc-2019-001017] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2019] [Revised: 02/19/2020] [Accepted: 03/24/2020] [Indexed: 01/21/2023] Open
Abstract
BACKGROUND The management of diabetes-related complications accounts for a large share of total carbon dioxide equivalent (CO2e) emissions. We assessed whether improving diabetes control in people with type 2 diabetes reduces CO2e emissions, compared with those with unchanging glycemic control. METHODS Using the IQVIA Core Diabetes Model, we estimated the impact of maintaining glycated hemoglobin (HbA1c) at 7% (53 mmol/mol) or reducing it by 1% (11 mmol/mol) on total CO2e/patient and CO2e/life-year (LY). Two different cohorts were investigated: those on first-line medical therapy (cohort 1) and those on third-line therapy (cohort 2). CO2e was estimated using cost inputs converted to carbon inputs using the UK National Health Service's carbon intensity factor. The model was run over a 50-year time horizon, discounting total costs and quality adjusted life years (QALYs) up to 5% and CO2e at 0%. RESULTS Maintaining HbA1c at 7% (53 mmol/mol) reduced total CO2e/patient by 18% (1546 kgCO2e/patient) vs 13% (937 kgCO2e/patient) in cohorts 1 and 2, respectively, and led to a reduction in CO2e/LY gain of 15%-20%. Reducing HbA1c by 1% (11 mmol/mol) caused a 12% (cohort 1) and 9% (cohort 2) reduction in CO2e/patient with a CO2e/LY gain reduction of 11%-14%. CONCLUSIONS When comparing people with untreated diabetes, maintaining glycemic control at 7% (53 mmol/mol) on a single agent or improving HbA1c by 1% (11 mmol/mol) by the addition of more glucose-lowering treatment was associated with a reduction in carbon emissions.

Identifying patients at risk of futile resuscitation: palliative care indicators in out-of-hospital cardiac arrest. BMJ Support Palliat Care 2019; 12:282-286. [PMID: 31530553 DOI: 10.1136/bmjspcare-2019-001828] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2019] [Revised: 08/22/2019] [Accepted: 09/04/2019] [Indexed: 11/04/2022]
Abstract
OBJECTIVES Patients with indicators for palliative care, such as those with advanced life-limiting conditions, are at risk of futile cardiopulmonary resuscitation (CPR) if they suffer out-of-hospital cardiac arrest (OHCA). Patients at risk of futile CPR could benefit from anticipatory care planning (ACP); however, the proportion of OHCA patients with indicators for palliative care is unknown. This study quantifies the extent of palliative care indicators and risk of CPR futility in OHCA patients. METHODS A retrospective medical record review was performed on all OHCA patients presenting to an emergency department (ED) in Edinburgh, Scotland in 2015. The risk of CPR futility was stratified using the Supportive and Palliative Care Indicators Tool. Patients with 0-2 indicators had a 'low risk' of futile CPR; 3-4 indicators had an 'intermediate risk'; 5+ indicators had a 'high risk'. RESULTS Of the 283 OHCA patients, 12.4% (35) had a high risk of futile CPR, while 16.3% (46) had an intermediate risk and 71.4% (202) had a low risk. 84.0% (68) of intermediate-to-high risk patients were pronounced dead in the ED or ED step-down ward; only 2.5% (2) of these patients survived to discharge. CONCLUSIONS Up to 30% of OHCA patients are being subjected to advanced resuscitation despite having at least three indicators for palliative care. More than 80% of patients with an intermediate-to-high risk of CPR futility are dying soon after conveyance to hospital, suggesting that ACP can benefit some OHCA patients. This study recommends optimising emergency treatment planning to help reduce inappropriate CPR attempts.

A cost-effectiveness evaluation of the originator follitropin alpha compared to the biosimilars for assisted reproduction in Germany. Int J Womens Health 2019; 11:319-331. [PMID: 31191040 PMCID: PMC6524790 DOI: 10.2147/ijwh.s193048] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2018] [Accepted: 03/16/2019] [Indexed: 11/23/2022] Open
Abstract
Background and objectives: Demand for assisted reproduction technology (ART) in Germany is high, with 100,844 treatment cycles during 2016. Many ART procedures involve ovarian stimulation with follicle stimulating hormone (FSH). Recently, biosimilar FSH products have become available. The objective of this study was to evaluate the cost-effectiveness of the recombinant FSH Gonal-f® (Originator) in comparison to biosimilar follitropin alfa, Bemfola® (Biosimilar 1) and Ovaleap® (Biosimilar 2), from a German payer perspective in terms of cost per live birth. Methods: A decision tree model was developed, based on one cycle of assisted reproduction, to compare the original product to biosimilars. Clinical inputs, including live birth rates and adverse event rates were obtained from published randomized trials. Cost inputs were obtained from publicly available German sources. Clinical inputs, model structure and methodology were based on previous publications and validated by a clinical expert. Results: Results indicated that the live birth rate is higher for the Originator compared to Biosimilar 1 (40.7% vs 32.1% respectively), and Biosimilar 2 (32.2% vs 26.8%). The average cost per live birth for women treated with the Originator was estimated to be lower than those who were treated with biosimilars: Originator vs Biosimilar 1 (€10,510 vs €12,192), Originator vs Biosimilar 2 (€12,590 vs €13,606). The analysis also found that the Originator is associated with an incremental cost-effectiveness of €4,168 and €7,540 per additional live birth versus Biosimilar 1 and Biosimilar 2 respectively. Sensitivity analysis indicated probabilities of pregnancy, embryo transfer and live birth, were key drivers of model costs. Scenario analysis confirmed the robustness of the model outcomes. Conclusion: This study suggests that treatment with the Originator could result in a lower cost per live birth in comparison to biosimilars. Further analysis using real-world data, when available, is recommended to validate the results of the present study.

Abstract
BACKGROUND Voice teachers are seeking increasing amounts of pedagogical instructions in the form of observerships, coursework, and clinical experiences. Yet to date there has been no formalized attempt to categorize or set guidelines for these educational experiences. OBJECTIVES The aim of this study was to investigate (a) the number of hours of observations required or electively completed during pedagogical training (voice lessons, masterclasses) and clinical observations; (b) the number of hours of mentorship (critical observation of a student by a mentor) during pedagogical training; and (c) differences in the training backgrounds of voice teachers based on the level of training, position, and genre. METHODS We distributed a survey to 700 voice teachers (102 respondents) of various levels from private to university and across age range of students. The surveys contained questions about the role of observation in the teacher's training. We ran descriptive analysis and examined whether the proportion of participants with ≥10 observation and mentorship hours was different for classical versus the other musical genres. RESULTS The number of respondents actively observing and being observed during their training was low. Most observations occurred within the classical and musical theater singing styles. Mentored critical observations of students were lower across genres than student observations, with the majority of respondents (67-92%) reporting no hours in genres other than classical. For all genres except classical, there was a larger percentage of respondents who reported teaching the genre than who reported receiving pedagogical training in the genre. Reported clinical voice observation hours were low (28.4% with ≥10 hours), and few respondents had >0 hours of operating room observation experience (11.8%). CONCLUSIONS There is wide disparity across genres in the number of hours of observation and critical mentoring, and voice teachers' genre of instruction does not frequently match with the genre of pedagogical instruction they have received. More research is needed to determine the significance of this mismatch and whether increased hours of observation and mentoring would benefit voice instruction.

Abstract
AIMS This open-label prospective phase I/II dose-escalation study determined the maximum tolerated dose (MTD) and then evaluated response, safety and feasibility of a novel combination of docetaxel, cisplatinum and capecitabine (DCC) in chemotherapy-naive patients with advanced oesophago-gastric carcinoma. MATERIALS AND METHODS Patients with adenocarcinoma or squamous cell carcinoma of the oesophagus or stomach, of good performance status, deemed too advanced for curative treatment, were given systematically increasing doses of 3 weekly DCC to ascertain the MTD. Phase II administered up to six cycles of DCC at the MTD, assessing response and toxicity. RESULTS Between November 2007 and November 2012, 15 patients were recruited into phase I and 41 into phase II. The MDT was a 21 day cycle of docetaxel 60 mg/m2 IV day 1, cisplatinum 60 mg/m2 IV day 1 and oral capecitabine 1000 mg/m2 daily in two divided doses for days 1-21. The most common phase II grade 3-4 toxicities were neutropenia 88% (10% febrile neutropenia), fatigue 15%, sensory neuropathy 10% and non-neutropenic infection 10%. The overall response rate was 51%, median progression-free survival was 7.4 months (confidence interval 6.7-9.4) and median overall survival was 10.9 months (confidence interval 7.7-13.7). CONCLUSION DCC was tolerable and feasible with promising efficacy, and may be suitable for future investigation in both first-line metastatic and neoadjuvant settings.

Abstract
Purpose The purpose of this study was to explore the relationship between visual acuity and utility (health-related quality of life) in diabetic macular edema (DME) using intravitreal aflibercept data. Methods The relationship between visual acuity in the best-seeing eye (BSE) and worse-seeing eye (WSE) and utility was explored using ordinary least squares (OLS) and random-effects models adjusted for different covariates (age, age2, sex, body mass index, smoking status, glycated hemoglobin, diabetes severity, comorbidities, and geographic region). Utility was measured using the EuroQoL-five dimensions questionnaire (EQ-5D) and Visual Functioning Questionnaire-Utility Index (VFQ-UI). For each model, coefficients (R2) were reported, and WSE/BSE was expressed as the ratio of coefficients (OLS models). Models were independent of treatment effects, and outcomes from all time points (up to week 100) were included where available. Results Data from 1320 patients with DME were analyzed. In all models, the association between visual acuity (BSE > WSE) was stronger with VFQ-UI- than EQ-5D-derived utilities. The estimated relationship between VFQ-UI and visual acuity in the BSE and WSE was robust, even with an increasing number of covariates. WSE/BSE coefficient ratios were similar across VFQ-UI OLS models (32%) compared with EQ-5D models (41%-48%). Actual (unadjusted) versus predicted data plots also showed a better fit with VFQ-UI- than EQ-5D-derived utilities. Conclusions These analyses show that VFQ-UI was more sensitive than EQ-5D-derived utilities for measuring the impact of visual acuity in the BSE and WSE. Visual acuity in the BSE was a major contributor to utility, but WSE is also important though to a lesser degree as shown by the coefficient ratios. These new data will be useful for health technology assessments in DME, where utilities data are lacking.

Abstract
BACKGROUND The use of video in healthcare is becoming more common, particularly in simulation and educational settings. However, video recording live episodes of clinical care is far less routine. AIM To provide a practical guide for clinical services to embed live video recording. MATERIALS AND METHODS Using Kotter's 8-step process for leading change, we provide a 'how to' guide to navigate the challenges required to implement a continuous video-audit system based on our experience of video recording in our emergency department resuscitation rooms. RESULTS The most significant hurdles in installing continuous video audit in a busy clinical area involve change management rather than equipment. Clinicians are faced with considerable ethical, legal and data protection challenges which are the primary barriers for services that pursue video recording of patient care. DISCUSSION Existing accounts of video use rarely acknowledge the organisational and cultural dimensions that are key to the success of establishing a video system. This article outlines core implementation issues that need to be addressed if video is to become part of routine care delivery. CONCLUSION By focussing on issues such as staff acceptability, departmental culture and organisational readiness, we provide a roadmap that can be pragmatically adapted by all clinical environments, locally and internationally, that seek to utilise video recording as an approach to improving clinical care.

Abstract
PURPOSE Fatigue is a prevalent and debilitating side effect of docetaxel chemotherapy in metastatic prostate cancer. A better understanding of the kinetics and nature of docetaxel-related fatigue may provide a framework for intervention. METHODS This secondary analysis was performed using the MOTIF database, from a phase III, randomised, double-blind, placebo-controlled study of modafinil (200 mg/day for 15 days) for docetaxel-related fatigue in men with metastatic prostate cancer [1]. The pattern of fatigue was analysed using the MDASI (MD Anderson Symptom Inventory) score. The impact of modafinil, cumulative docetaxel exposure, age and smoking status on fatigue kinetics were explored. Fatigue-related symptoms were assessed using the SOMA6 (fatigue and related symptoms) subset of the SPHERE (Somatic and Psychological Health Report). Mood was tracked using the short form 36 health survey questionnaire (SF-36). RESULTS Across four docetaxel cycles, fatigue scores were higher in the first week and decreased over weeks two and three. Whilst men randomised to modafinil had reduced fatigue scores, cumulative docetaxel had little impact. Younger men (55-68 years) had significantly reduced fatigue scores, whereas current and ex-smokers had higher scores. There was no significant change in mood status or haemoglobin across treatment cycles. Men described both 'somnolence' and 'muscle fatigue' contributing significantly to their symptom complex. CONCLUSIONS Assessment and management of docetaxel-related fatigue remains an important challenge. Given the complex, multifactorial nature of fatigue, identification through structured interview and interventions targeted to specific 'at risk' groups may be the most beneficial. Understanding the temporal pattern (kinetics) and nature of fatigue is critical to guide this process.

Abstract
Objective This study compared the effectiveness of Er:YAG laser-activated irrigation (PIPS), passive ultrasonic irrigation (PUI) with EndoUltra and standard needle irrigation (SNI) in the removal of calcium hydroxide [Ca(OH)2] from the mesial roots of Weine Type II mandibular molars. Material and Methods Thirty mandibular molars were screened by µCT for the presence of mesial roots with complex intra-canal anatomy and a common apical foramen. The teeth were enlarged to a standardized 25/.06 preparation and filled with Ca(OH)2 paste. Specimens were divided into three groups (n=10) according to the technique used for Ca(OH)2 removal: PIPS, at 15 Hz and 20 mJ using a 9 mm long, 600 µm diameter tip; PUI using a 15/.02 tip; and SNI (30 Ga. side-vented needle). Equal volumes of 8.25% NaOCl and 17% EDTA were used in all groups. µCT was used to measure the initial amount of Ca(OH)2 present and to assess the residual volume of Ca(OH)2 following each irrigation protocol. Data were analyzed using Tukey HSD and Kruskal-Wallis tests (α=5%). Results The mean volume of Ca(OH)2 before removal was significantly higher in the coronal third than in the middle and apical third (p<0.001). Ca(OH)2 was similarly removed from the coronal and middle thirds with the three methods used (p>0.05). PIPS (median 0%; IQR: 0-0) showed significant higher Ca(OH)2 removal in the apical third than PUI (median 100%, IQR: 85-100) and SNI (median 47%; IQR: 16-72) (p<0.001). Conclusions PIPS laser-activation was more effective for the removal of Ca(OH)2 from mesial roots of mandibular molars with Weine Type II canal configurations than PUI with EndoUltra and SNI.

Abstract
Video evaluation of resuscitation is becoming increasingly integrated into practice in a number of clinical settings. The purpose of this review article is to examine how video may enhance clinical care during resuscitation. As healthcare and available therapeutic interventions evolve, re-evaluation of accepted paradigms requires data to describe current practice and support change. Analysis of video recordings affords creation of a framework to evaluate individual and team performance and develop unique and tailored strategies to optimise care delivery. While video has been used in a number of non-clinical settings, there has been a recent increase of video systems in the prehospital and other clinical areas. This paper reviews the key opportunities in the emergency department-based resuscitation setting to enhance ergonomics, technical and non-technical skills-at both team and individual level-through video-assisted care performance analysis and feedback.

Abstract
BackgroundThe feasibility study aims to evaluate the use of EEG in measuring workload during a simulated intravenous cannulation task. Cognitive workload is strongly linked to performance, but current methods to assess workload are unreliable. The paper presents the use of EEG to compare the cognitive workload between an expert and novice group completing a simple clinical task.Methods2 groups of volunteers (10 final year medical students and 10 emergency medicine consultants) were invited to take part in the study. Each participant was asked to perform 3 components of the simulation protocol: intravenous cannulation, a simple arithmetic test and finally these tasks combined. Error rate, speed of task completion and an EEG-based measure of cognitive workload were recorded for each element.ResultsEEG cognitive workload during the combined cannulation and arithmetic task is significantly greater in novice participants when compared with expert operators performing the same task combination. EEG workload mean measured for novice and experts was 0.62 and 0.54, respectively (p=0.001, 95% CI 0.09 to 0.30). There was no significant difference between novice and expert EEG workload when the tasks were performed individually.ConclusionsEEG provides the opportunity to monitor and analyse the impact of cognitive load on clinical performance. Despite the significant challenges in set up and protocol design, there is a potential to develop educational interventions to optimise clinician's awareness of cognitive load. In addition, it may enable the use of metrics to monitor the impact of different interventions and select those that optimise clinical performance.

A longitudinal study of hepatitis C virus testing and infection status notification on behaviour change in people who inject drugs. J Epidemiol Community Health 2015; 69:745-52.

Abstract
BACKGROUND Hepatitis C virus (HCV) testing and counselling have the potential to impact individual behaviour and transmission dynamics at the population level. Evidence of the impact of an HCV-positive status notification on injection risk reduction is limited. The objective of our study was to (1) assess drug and alcohol use and injection risk behaviours following notification; (2) to compare behaviour change in people who inject drugs (PWID) who received a positive test result and those who remained negative; and (3) to assess the effect of age on risk behaviour. METHODS Data from the International Collaboration of Incident HIV and HCV Infection in Injecting Cohorts (InC3 Study) were analysed. Participants who were initially HCV seronegative were followed prospectively with periodic HCV blood testing and post-test disclosure and interview-administered questionnaires assessing drug use and injection behaviours. Multivariable generalised estimating equations were used to assess behavioural changes over time. RESULTS Notification of an HCV-positive test was independently associated with a small increase in alcohol use relative to notification of a negative test. No significant differences in postnotification injection drug use, receptive sharing of ancillary injecting equipment and syringe borrowing postnotification were observed between diagnosis groups. Younger PWID receiving a positive HCV test notification demonstrated a significant increase in subsequent alcohol use compared with younger HCV negative. CONCLUSIONS The proportion of PWID reporting alcohol use increased among those receiving an HCV-positive notification, increased the frequency of alcohol use postnotification, while no reduction in injection drug use behaviours was observed between notification groups. These findings underscore the need to develop novel communication strategies during post-test notification to improve their impact on subsequent alcohol use and risk behaviours.

Abstract
Traditionally, healthcare professionals have been expected to acquire technical skills while minimal attention has been paid to the non-technical skills (NTS) they require to work in complex health environments, such as resuscitation rooms. This article explains the importance of NTS in improving patient outcomes and why a model of dynamic nurse leadership is useful in resuscitative care.
