Abstract
PURPOSE/OBJECTIVE(S) To evaluate the long-term outcomes and toxicity of a nonsurgical prostatic urethral lift system in patients with prior prostate cancer radiation therapy (RT). MATERIALS/METHODS From 2018 to 2020, nineteen patients with a history of prior prostate RT underwent a nonsurgical prostatic urethral lift (PUL) procedure for lower urinary track symptoms (LUTS) refractory to alpha blocker medications. Prostate cancer RT was completed a median of 17.8 months (IQR 13.4-27.4) prior to PUL procedure. All patients were assessed with IPSS/quality of life (QOL) scores and urinary post void residual (PVR) ultrasound before and after PUL. Patients were also assessed for ability to discontinue alpha blockade medications for their LUTS and any post PUL toxicity based on CTCAE v5.0 criteria. RESULTS All patients underwent successful placement of the PUL implants. Median pre-PUL IPSS score was 20 (IOR 17.5-22.5) and the median prostate volume was 41cc (IQR 33-49). Median follow up was 22 months (IQR 5-30). The average improvement in IPSS score was 8.5 points (IRQ 5.5-11) at 3 months and 7.5 points (IQR 6-10) at last follow-up. Two patients (10%) initially had improvement in IPSS score at 3 months with subsequent significant increase in IPSS (>5 points) at last follow-up. Overall, there was minimal change in reported QOL scores (median 0, IQR 0-1.75). The average reduction in PVR was 90cc. The percentage of patients able to discontinue alpha blockade at last follow-up was 68%. There was no grade 3 or higher GU toxicity in either group. CONCLUSION Use of a nonsurgical prostatic urethral lift system in patients with prior prostate RT refractory to alpha blocker medications results in significant long-term improvement of LUTS after radiation therapy for the majority of patients with minimal toxicity.

Childhood-Onset Lupus Nephritis in the Childhood Arthritis and Rheumatology Research Alliance Registry: Short-Term Kidney Status and Variation in Care. Arthritis Care Res (Hoboken) 2023; 75:1553-1562. [PMID: 36775844 PMCID: PMC10500561 DOI: 10.1002/acr.25002] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Revised: 07/14/2022] [Accepted: 08/16/2022] [Indexed: 11/10/2022]
Abstract
OBJECTIVE The goal was to characterize short-term kidney status and describe variation in early care utilization in a multicenter cohort of patients with childhood-onset systemic lupus erythematosus (cSLE) and nephritis. METHODS We analyzed previously collected prospective data from North American patients with cSLE with kidney biopsy-proven nephritis enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry from March 2017 through December 2019. We determined the proportion of patients with abnormal kidney status at the most recent registry visit and applied generalized linear mixed models to identify associated factors. We also calculated frequency of medication use, both during induction and ever recorded. RESULTS We identified 222 patients with kidney biopsy-proven nephritis, with 64% class III/IV nephritis on initial biopsy. At the most recent registry visit at median (interquartile range) of 17 (8-29) months from initial kidney biopsy, 58 of 106 patients (55%) with available data had abnormal kidney status. This finding was associated with male sex (odds ratio [OR] 3.88, 95% confidence interval [95% CI] 1.21-12.46) and age at cSLE diagnosis (OR 1.23, 95% CI 1.01-1.49). Patients with class IV nephritis were more likely than class III to receive cyclophosphamide and rituximab during induction. There was substantial variation in mycophenolate, cyclophosphamide, and rituximab ever use patterns across rheumatology centers. CONCLUSION In this cohort with predominately class III/IV nephritis, male sex and older age at cSLE diagnosis were associated with abnormal short-term kidney status. We also observed substantial variation in contemporary medication use for pediatric lupus nephritis between pediatric rheumatology centers. Additional studies are needed to better understand the impact of this variation on long-term kidney outcomes.

Abstract
On 26 September 2022, the Double Asteroid Redirection Test (DART) spacecraft struck Dimorphos, a satellite of the asteroid 65803 Didymos1. Because it is a binary system, it is possible to determine how much the orbit of the satellite changed, as part of a test of what is necessary to deflect an asteroid that might threaten Earth with an impact. In nominal cases, pre-impact predictions of the orbital period reduction ranged from roughly 8.8 to 17 min (refs. 2,3). Here we report optical observations of Dimorphos before, during and after the impact, from a network of citizen scientists' telescopes across the world. We find a maximum brightening of 2.29 ± 0.14 mag on impact. Didymos fades back to its pre-impact brightness over the course of 23.7 ± 0.7 days. We estimate lower limits on the mass contained in the ejecta, which was 0.3-0.5% Dimorphos's mass depending on the dust size. We also observe a reddening of the ejecta on impact.

An investigation into the clinical scope of practice of MRI reporting radiographers within the United Kingdom. Radiography (Lond) 2023; 29:489-495. [PMID: 36878158 DOI: 10.1016/j.radi.2023.02.015] [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: 12/31/2022] [Revised: 02/01/2023] [Accepted: 02/15/2023] [Indexed: 03/07/2023]
Abstract
INTRODUCTION Radiographers have been reporting Magnetic Resonance Imaging (MRI) examinations for over ten years, and there is an increasing body of evidence confirming the efficacy of this role expansion. However, little is known about the clinical scope of practice of radiographers undertaking this enhanced level of practice. The aim of this study was to investigate the clinical scope of practice of MRI reporting radiographers within the United Kingdom (UK). METHODS MRI reporting radiographers who are actively reporting within the UK were invited to participate in a short online survey investigating the anatomical areas reported, clinical referral pathways and onward referral practices they routinely undertake. The survey was distributed via social media channels with snowball sampling encouraged. RESULTS There were n = 14 responses received, with an estimated response rate of 21.5%. The majority (93% n = 13/14) practised in England, with one response from Scotland. All participants (n = 14/14) undertook reporting of general practitioner (GP) and community healthcare practitioner's referrals, with 93% reporting for outpatient referrers. There was statistically significant variation in the anatomical areas reported when compared against those qualified less than two years and those qualified over ten years (p = 0.003). No other statistically significant variation was seen. CONCLUSION There was no statistical difference in the implementation of MRI reporting by radiographers identified. All participants indicated reporting for GP and community healthcare practitioner referrers which align well with the implementation of community diagnostic centre rollout across the UK. IMPLICATION FOR PRACTICE This is believed to be the first study of its kind in the realm of MRI reporting. The study has suggested that MRI reporting radiographers are well placed to contribute to the rollout of community diagnostic centres within the UK.

Cohort profile: the ESC EURObservational Research Programme Non-ST-segment elevation myocardial infraction (NSTEMI) Registry. EUROPEAN HEART JOURNAL. QUALITY OF CARE & CLINICAL OUTCOMES 2022; 9:8-15. [PMID: 36259751 DOI: 10.1093/ehjqcco/qcac067] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/07/2022] [Accepted: 10/11/2022] [Indexed: 11/12/2022]
Abstract
AIMS The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation. METHODS AND RESULTS Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (in-hospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, pre-hospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin. CONCLUSION The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality.

Intraarticular steroids as DMARD-sparing agents for juvenile idiopathic arthritis flares: Analysis of the Childhood Arthritis and Rheumatology Research Alliance Registry. Pediatr Rheumatol Online J 2022; 20:107. [PMID: 36434731 PMCID: PMC9701017 DOI: 10.1186/s12969-022-00770-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2022] [Accepted: 11/08/2022] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND Children with juvenile idiopathic arthritis (JIA) who achieve a drug free remission often experience a flare of their disease requiring either intraarticular steroids (IAS) or systemic treatment with disease modifying anti-rheumatic drugs (DMARDs). IAS offer an opportunity to recapture disease control and avoid exposure to side effects from systemic immunosuppression. We examined a cohort of patients treated with IAS after drug free remission and report the probability of restarting systemic treatment within 12 months. METHODS We analyzed a cohort of patients from the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry who received IAS for a flare after a period of drug free remission. Historical factors and clinical characteristics and of the patients including data obtained at the time of treatment were analyzed. RESULTS We identified 46 patients who met the inclusion criteria. Of those with follow up data available 49% had restarted systemic treatment 6 months after IAS injection and 70% had restarted systemic treatment at 12 months. The proportion of patients with prior use of a biologic DMARD was the only factor that differed between patients who restarted systemic treatment those who did not, both at 6 months (79% vs 35%, p < 0.01) and 12 months (81% vs 33%, p < 0.05). CONCLUSION While IAS are an option for all patients who flare after drug free remission, it may not prevent the need to restart systemic treatment. Prior use of a biologic DMARD may predict lack of success for IAS. Those who previously received methotrexate only, on the other hand, are excellent candidates for IAS.

Abstract
Abstract
Background
The Department of Health published new guidance in November 2020 “Vitamin D advice for people aged 65 and older” which recommended that all adults ≥65 years should be supplemented with 15micrograms of Vitamin D daily. 55.5% of adults ≥65 years have insufficient/deficient vitamin D levels in winter (TILDA 2020). The Frailty Intervention Team (FIT) assess frail adults ≥65 years in the Emergency Department using medication review and Comprehensive Geriatric Assessment to identify vitamin D supplementation. The audit aim was to determine if compliance with the new guideline improved since the initial audit in January 2021.
Methods
All patients who had a medicine reconciliation completed by the FIT Pharmacist in January 2022 were included in a retrospective audit. Patients were identified from the pharmacist’s worklist. Data was collected from a Hospital Clinical System using a Microsoft Excel®. The data recorded included: Age, Sex, Rockwood Clinical Frailty Score (CFS) and vitamin D supplementation.
Results
The FIT Pharmacist completed 66 medicine reconciliations in January 2022. The mean age (+/-SD) was 82.4 (+/-7.6) years.The male to female ratio was 1:1.75The median CFS was 5 (mildly/moderately frail) with an IQR of 1.
68% (n=45) were prescribed vitamin D. Of those 89% (n=40) were prescribed a supplement containing at least 15micrograms of vitamin D. 32% (n=21) were not prescribed any vitamin D supplementation. 8% (n=5) were prescribed doses lower than 15micrograms of vitamin D.
Conclusion
Compliance with the new guideline was 61% (n=40) in comparison to 65% (n=39) in the initial audit. The results are reflective of adherence to the new guideline in the community. The policy update and education provided post the initial audit has possibly influenced the prescribing of vitamin D in the acute setting which unless patients are re-presenting will not have been captured in the outcome of this re-audit.

Abstract
Abstract
Background
Many older people are brought to the Emergency Department (ED) who do not require acute hospital admission but there are risks to these patients if this occurs. The Frailty Intervention Team (FIT) are an interdisciplinary team based in the ED including physiotherapy, occupational therapy, speech and language therapy, dietetics, pharmacy, advanced nurse practitioners, and a geriatric registrar and consultant. They assess frail older patients and suggest alternative care pathways to admission. We aimed to investigate the impact of FIT on admission avoidance, bed days saved and to obtain patient feedback on their experience.
Methods
Routinely collected data from May 2021 to April 2022 was reviewed retrospectively. An anonymous patient feedback questionnaire was posted to 40 patients randomised from the FIT worklist between January to May 2022.
Results
2,025 Comprehensive Geriatric Assessments (CGA) were completed between May 2021 and April 2022. 38% percent of patients were discharged home, 45% of this number had follow-up arranged. 104 patients were transferred directly to an offsite bed, mostly rehabilitation. We estimate we avoided 51 admissions to the acute hospital per month, almost half of these were patients admitted to the hospital and, who we discharged to alternative care pathways or home. The average length of stay in April 2022 was 22 days – by avoiding 615 admissions between May 2021 and April 2022 we have saved 13,530 bed days at an estimated cost saving of almost €11 million. 15 completed questionnaires were returned. 73% were very satisfied with their experience. 87% felt the FIT team helped facilitate their discharge from ED. The main themes identified from open ended questions included thorough assessment, patient centred care and satisfaction with early intervention and discharge.
Conclusion
A Frailty Intervention Team is a cost effective and patient centred way of avoiding unnecessary admissions for older people presenting to the ED.

Abstract
Abstract
Background
Inappropriate polypharmacy and ‘Potentially Inappropriate Prescriptions’ (PIP) are associated with increased morbidity and hospitalisation, in particular among frail older persons. A structured medication review, in conjunction with a Comprehensive Geriatric Assessment (CGA), can address PIP. The aim of the study was to review Frail Intervention Team (FIT) pharmacist interventions for frail, older adults presenting to the Emergency Department (ED) and experiencing medication compliance difficulties, polypharmacy and PIP.
Methods
Patients identified for medication review included those experiencing polypharmacy or medication compliance issues, presenting with a fall, delirium and/or frailty syndromes or complex comorbidities. The medication review process involved completion of medicines reconciliation and medication appropriateness review in accordance with the 7-Steps Medication Review Model (Scottish Government Polypharmacy Model of Care Group, 2018). Pharmacist optimisation recommendations were reviewed by a Consultant Geriatrician or Registrar and discussed with the patient prior to implementation.
Results
The FIT Pharmacist completed medication reviews for 765 patients between May 2021 and April 2022. The mean age (+/-SD) was 83.1 (+/-7.0) years with a median Clinical Frailty Score (CFS) of 5 (mildly/moderately frail). Medication Optimisation recommendations were actioned in 63% (n=483) of patients reviewed. The most commonly encountered PIP’s included: excessive anti-hypertensive/diuretic therapy, long-term acid-suppression therapy, anticholinergics and long-term prophylactic antimicrobials. Prescribing opportunities identified included: bone protection, laxatives and pain management.
Conclusion
FIT pharmacist review, in conjunction with the CGA, led to medication optimisation interventions in the frail older adult cohort presenting to the ED. Future studies should examine the impact of medication review on patient outcomes post-discharge.

Abstract
Abstract
Aim
To determine the orthopaedic trauma theatre efficiency in two large major trauma centres (MTCs) in Scotland before and after the outbreak of Coronavirus disease (COVID-19) pandemic.
Method
All trauma patients presented to the North and East of Scotland's MTCs prior to the outbreak of COVID-19 (7th May to 7th June 2019), during the first peak of COVID-19 (7th May to 7th June 2020), after Aerosol Generating Procedures updates (7th November to 7th December 2020) and the ‘new normal’ (7th May to 7th June 2021) were retrospectively reviewed. Training opportunities and theatre time were compared. The Kruskall-Wallis test was used.
Results
There were no significant differences in the length of hospital stay (p=0.117, 0.065) and time from injuries and surgery within groups in both MTCs (p=0.508, 0.384). The pandemic has negatively affected the anaesthetic and surgical preparation time, time between end of procedure and send for next case, and turnover time, with more profound effect on the North of Scotland's MTC. The trainee's involvement as main surgeon had decreased with the outbreak of the pandemic, with the junior trainees being affected most severely in North of Scotland. The time taken for patient to arrive to theatre after sending and total downtime were twice as long in the North of Scotland.
Conclusion
The COVID-19 pandemic has negatively impacted the orthopaedic trauma theatre efficiency and training opportunities. Actions should be taken to improve the turnover time to maximise theatre efficiency while prioritizing training opportunities.

Abstract
DUNE is a dual-site experiment for long-baseline neutrino oscillation studies, neutrino astrophysics and nucleon decay searches. ProtoDUNE Dual Phase (DP) is a 6 × 6 × 6 m 3 liquid argon time-projection-chamber (LArTPC) that recorded cosmic-muon data at the CERN Neutrino Platform in 2019-2020 as a prototype of the DUNE Far Detector. Charged particles propagating through the LArTPC produce ionization and scintillation light. The scintillation light signal in these detectors can provide the trigger for non-beam events. In addition, it adds precise timing capabilities and improves the calorimetry measurements. In ProtoDUNE-DP, scintillation and electroluminescence light produced by cosmic muons in the LArTPC is collected by photomultiplier tubes placed up to 7 m away from the ionizing track. In this paper, the ProtoDUNE-DP photon detection system performance is evaluated with a particular focus on the different wavelength shifters, such as PEN and TPB, and the use of Xe-doped LAr, considering its future use in giant LArTPCs. The scintillation light production and propagation processes are analyzed and a comparison of simulation to data is performed, improving understanding of the liquid argon properties.

Abstract
BACKGROUND Social determinants of health (SDH) greatly influence outcomes during the first year of treatment in rheumatoid arthritis, a disease similar to polyarticular juvenile idiopathic arthritis (pJIA). We investigated the correlation of community poverty level and other SDH with the persistence of moderate to severe disease activity and functional disability over the first year of treatment in pJIA patients enrolled in the Childhood Arthritis and Rheumatology Research Alliance Registry. METHODS In this cohort study, unadjusted and adjusted generalized linear mixed effects models analyzed the effect of community poverty and other SDH on disease activity, using the clinical Juvenile Arthritis Disease Activity Score-10, and disability, using the Child Health Assessment Questionnaire, measured at baseline, 6, and 12 months. RESULTS One thousand six hundred eighty-four patients were identified. High community poverty (≥20% living below the federal poverty level) was associated with increased odds of functional disability (OR 1.82, 95% CI 1.28-2.60) but was not statistically significant after adjustment (aOR 1.23, 95% CI 0.81-1.86) and was not associated with increased disease activity. Non-white race/ethnicity was associated with higher disease activity (aOR 2.48, 95% CI: 1.41-4.36). Lower self-reported household income was associated with higher disease activity and persistent functional disability. Public insurance (aOR 1.56, 95% CI 1.06-2.29) and low family education (aOR 1.89, 95% CI 1.14-3.12) was associated with persistent functional disability. CONCLUSION High community poverty level was associated with persistent functional disability in unadjusted analysis but not with persistent moderate to high disease activity. Race/ethnicity and other SDH were associated with persistent disease activity and functional disability.

The Successful Implementation of Day Case Tonsillectomy. IRISH MEDICAL JOURNAL 2022; 115:518. [PMID: 35279052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/14/2023]
Abstract
Objective Day case tonsillectomy is standard practice in many international centres, and is widespread across the UK. In Ireland, implementation has been slow for multiple reasons. Our unit aimed to introduce day case tonsillectomy, following a pilot programme. Following a year of implementation we have reaudited our practice. We hypothesised that day case tonsillectomy is a practical and favourable solution to facilitate access to surgery in the context of long waiting times for ENT surgery. Methods This was a prospective audit collecting data on day case tonsillectomy. All patients for day case tonsillectomy were selected in OPD according to our inclusion criteria. We recorded demographical data, surgical technique, length of stay, failed discharges, bleeding rate and readmission rate. Results There was one primary haemorrhage within 24 hours of surgery (0.08%). There were 16 secondary bleeds, giving a rate of 13.9%. Of these, four patients required a return to theatre for the cessation of bleeding (3.5%). There was no statistical significance in bleed rate between surgical technique. Failed discharge rate was 6%. The average time from extubation to discharge was 6 hours and 53 minutes. Conclusions Our experience of day case tonsillectomy is that it is safe, feasible and efficient in a selected group of patients. This can expedite long waiting times for tonsillectomy, and improve access to overnight beds for other cases. Our numbers represent the first unit in Ireland to have 2 year of experience with data showing successful implementation.

Abstract
Poroid hidradenomas are a rare subtype of hidradenoma. A Veteran’s Administration patient presented with a mobile, cystic scalp lesion. Intraoperatively the mass spontaneously ruptured. We hope clinicians will consider this entity on their differential when treating patients presenting with similar scalp lesions and intraoperative findings.

Concordance between a neuroradiologist, a consultant radiologist and trained reporting radiographers interpreting MRI head examinations: An empirical study. Radiography (Lond) 2020; 27:475-482. [PMID: 33218744 DOI: 10.1016/j.radi.2020.10.016] [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: 09/21/2020] [Revised: 10/23/2020] [Accepted: 10/27/2020] [Indexed: 11/16/2022]
Abstract
INTRODUCTION This study assessed agreement between MRI reporting radiographers and a consultant radiologist compared with an index neuroradiologist when reporting MRI head (brain/internal auditory meati [IAMs]) examinations. The effect on patient management of any discordant reports was also examined. METHODS Two trained MRI reporting radiographers (RRs), a consultant radiologist (CR) and an index neuroradiologist (INR) reported on a random sample of 210 MRI examinations. The radiographers reported during clinical practice and the radiologists in clinical practice conditions. Two independent consultant physicians (neuro-rehabilitation and neuropsychiatry) compared these reports with the index neuroradiologist report for agreement and the clinical importance of discrepant reports. RESULTS Overall observer agreement between the RRs and CR was comparable in relation to agreement with the INR: RR; 93/210 (44.3%); and the CR; 83/210 (39.4%) for all head MRI examinations (p = 0.32). For brain examinations the difference was similar: RR; 64/180 (35.6%); and CR; 54/190 (30.0%), p = 0.26. Agreement rates for the IAMs examinations were identical, 29/30 (97.7%). For all head MRI examinations (n = 210) there was a very small observed difference of <0.5% in mean agreement between the reporting radiographers and the consultant radiologist (p = 0.92) for examinations where a major disagreement would have been likely to have led to a change in patient management. CONCLUSION MRI reporting radiographers reported during clinical practice on MRI head examinations to a level of agreement comparable with a consultant radiologist. IMPLICATIONS FOR PRACTICE This is an area in which radiographers could provide additional reporting roles to the reporting service to increase capacity. Wider potential benefits include cost-effectiveness and role development/retention of radiographers.

Abstract
Abstract
Background
In the United States (US) when opioid use disorder (OUD) is treated with medication assisted treatment (MAT), many patients in MAT will relapse into active opioid use during the recovery process. About 23% drop out of treatment within 3 months, and 40-50% drop out within 6 months of MAT start. Using the Anderson and Newman (2005) Framework for Health Services Utilization, 27 variables reflecting predisposing, enabling, and need factors were used to examine the impact on the number of days patients were retained in treatment.
Methods
One MAT clinic in rural Michigan used random sample of archival records (n = 390) OUD patients (DSM-V-TR code 304.00, ICD-10 code F11.20) between Jan. 1, 2014 and Nov. 21, 2018 with prescribed buprenorphine as part of MAT program. The first set of linear regressions (backward elimination) defined significant variables for each factor, and the final model included significant variables to predict length of retention in MAT.
Results
The first step identified legal issues (predisposing), MSHN insurance, distance to clinic, ability to drive, mental health diagnosis, and homelessness (enabling factors); Zung self-reporting depression score, starting dose, past suicide attempt, Hep-C status, and method of use (needs factor) as statistically significant to be used in the final model, controlling for age and gender. Starting dose (unstandardized b = 136.8, 95%CI 98.0, 175.6), driving license (b = 68.3, CI 13.2, 123.4), distance to clinic (b=-1.1, CI -2.2, -0.5) had statistical impact on the length of stay in MAT.
Discussion
This case study identified enabling factors (starting dose and access to clinic) affecting length of participation in MAT. Other factors warranting provider attention were identified for rural OUD patients.
Conclusions
Evidence based guidelines for starting doses are needed to increase MAT effectiveness. MAT services should consider distance to clinic as a factor of successful treatment.
Key messages
Evidence based guidelines for starting doses are needed to increase MAT effectiveness. Opiood treatment services should consider distance to clinic as a factor of successful treatment.

Abstract
Introduction
A quarter of women Veterans (WVs) receiving VA healthcare meet diagnostic criteria for both insomnia disorder and posttraumatic stress disorder (PTSD). Cognitive Behavioral Therapy for Insomnia (CBT-I) is effective at improving sleep among individuals with comorbid psychiatric conditions; however, no studies have examined the impact of CBT-I in women with insomnia plus PTSD. The current analyses examined changes in sleep symptoms, quality of life (QoL), and mental health symptoms from pre- to post-CBT-I in WVs with and without PTSD.
Methods
This was a secondary analysis of 75 WVs with insomnia (32 with probable PTSD), who received CBT-I within a behavioral sleep intervention study (NCT02076165). Measures completed at baseline, posttreatment, and 3-month follow-up included: insomnia severity (Insomnia Severity Index, ISI), sleep quality (Pittsburgh Sleep Quality Index, PSQI), PTSD symptoms (PTSD Checklist-5, PCL-5; probable PTSD=total score ≥33), depressive symptoms (Patient Health Qestionnaire-9, PHQ-9), and mental and physical quality of life (Short Form Health Survey, SF-12). One sample T-tests examined changes in ISI, PSQI, PHQ-9, PCL-5, and SF-12 from baseline to posttreatment and baseline to follow-up. Two samples T-tests compared change scores in ISI, PSQI, PHQ-9, and SF-12 between participants with and without PTSD.
Results
There were significant improvements in ISI (p≤.001), PSQI (p≤.001), PHQ-9 (p≤.001), PCL-5 (p=.001), and SF-12 mental (p≤.001) and physical (p=.03) from baseline to posttreatment and 3-month follow-up (p≤.001-.01). There were no significant change score differences between WVs with and without PTSD from baseline to posttreatment (p=.06-.98) or 3-month follow-up (p=.09-.93).
Conclusion
CBT-I appears to be an effective treatment to improve insomnia symptoms among WVs with and without PTSD, and may reduce psychiatric symptoms as well. These findings suggest WVs with comorbid insomnia and PTSD benefit from CBT-I. The appropriate sequencing of CBT-I and PTSD treatments remains potentially important, but unstudied.

Abstract
One common adverse effect following breast-conservation surgery and adjuvant radiation is lymphedema. While lymphedema of the arm has been well-characterized, there has been less investigation into lymphedema of the breast. We sought to characterize rates of breast lymphedema (BLE) in women with early-stage breast cancer and identify potential predictors in its development. Two hundred and thirty consecutive patients treated with lumpectomy and adjuvant whole breast radiation therapy (WBRT) from January 2016 - June 2017 were included. All patients were seen in our lymphedema monitoring clinic for baseline and at least one follow-up lymphedema measurement. BLE grades were assigned by trained nurses in the lymphedema clinic. Data regarding patient demographic and treatment factors were extracted from the electronic medical record. Comparisons between groups were made using Chi-Square analysis performed in SAS. The median age of the sample was 62 (range 31-90). Median follow-up from surgery was 15.3 months. Forty-three patients were diagnosed with lymphedema of the breast (18.7%). Rates of grade 1 and 2 BLE were 93% and 7%, respectively; there were no cases of severe lymphedema. Sixty-three percent of cases resolved by last follow-up with treatment recommendations. There was no association between development of BLE and patient factors investigated, including age, T stage, radiation dose and fractionation, lymph node biopsy, number of lymph nodes removed, development of arm lymphedema, and use of chemotherapy. Tumor subtype was found to be significant (P = 0.04) and there was a trend towards significance for receipt of trastuzumab (P = 0.09). BLE is a distinct entity from arm lymphedema and is a common finding in women treated with breast-conserving surgery and adjuvant WBRT. It is a generally mild and self-limiting process. There were no treatment or patient-related factors that correlated with increased risk of lymphedema development in our sample except for HER-2 positive disease and receipt of trastuzamab.

197 The use of photostimulation to enhance oocyte cytoplasmic maturation. Reprod Fertil Dev 2020.

Abstract
Phototherapy uses monochromatic light from low-power lasers and light-emitting diodes (LEDs) to modulate biological processes. It has been proposed that the red-to-near infrared optical region (~600-1000nm) enhances cellular metabolic activity by activation of the mitochondrial respiratory chain. However, photostimulation induces the generation of oxide free radicals and could create oxidative stress in exposed cells. The main objective was to use photostimulation to affect the cumulus-oocyte complex metabolic state, aiming to enhance cytoplasmic maturation rates and subsequent embryonic development. A secondary objective was to determine the toxicity of the proposed photostimulation protocol. Abattoir-derived ovaries were used. All media was from IVF Biosciences (Falmouth, Cornwall, UK). Follicles 2 to 6mm in diameter were aspirated. Oocytes with compact cumulus and homogeneous cytoplasm were selected, and 50 oocytes/well were placed in invitro maturation medium (0h) and incubated at 38.5°C in 5% CO2 in air with high humidity in the presence (treatment=exposure for 2min to super-bright LED 1 and 2h after the beginning of maturation; LED wavelength of 660-665 nm; NTE30041; NTE Electronics Inc.) or absence (Control) of light. After maturation (22h), oocytes were split into two wells (25 oocytes/well) and subjected to IVF with semen from two different bulls for 18 to 20h. Cumulus cells were separated by vortexing, zygotes were placed in invitro culture medium, and incubated at 38.5°C in 5% CO2 in air with high humidity. Culture medium was renewed every 48h. Cleavage, morula, and blastocyst rates were recorded as a percentage of the number of oocytes subjected to IVF per treatment. The experiment was replicated 4 times. Statistical analysis was conducted using the Mixed procedure (SAS 9.4, SAS Institute Inc.) with repeated-measures and autoregressive covariance. The model's random effect was well within treatment. Fixed effects were bull, stage of development, and treatment. There was no difference (P=0.8) between treatments for any stage of development measured (cleavage: 76.4±2.7 vs. 74.8±4.1; morula: 36.1±4.8 vs. 35.9±5.8; blastocyst: 20.8±3.2 vs. 20.6±4.4 for control and treatment respectively; mean±s.e.). Sire affected development: bull 1 had a greater percentage (P<0.05) cleavage (82.9±0.02 vs. 68.3±0.02), morula (42.6±0.05 vs. 29.4±0.04), and blastocyst (27.8±0.04 vs. 13.6±0.01) development than bull 2. There was no treatment×bull interaction (P=0.9). In conclusion, there were no stimulatory or toxic effects of this preliminary photostimulation protocol. Further research is needed to develop an optimal protocol that shows a metabolic effect and, potentially, an enhancement of invitro cytoplasmic maturation rates and subsequent embryonic development.

Abstract
AIM The study explored the views and attitudes of nurses and physicians on family presence during resuscitation in emergency departments in Brazil. BACKGROUND International emergency associations endorse family presence during resuscitation; however, the extent to which it is practiced remains unclear, particularly in the Brazilian context. Research of emergency staff views and attitudes towards this practice is desirable so that actions can be identified to support families at the bedside. METHODS A qualitative research was conducted. Thirty-two health professionals (11 physicians and 21 nurses) working in two emergency departments in southern Brazil were purposefully recruited in January 2015. In-depth interviews were conducted, and data were analysed using content analysis. FINDINGS Nurses and physicians found family presence during resuscitation controversial and the general attitude towards this practice was negative. They reported that 'changes are needed' to adapt hospital infrastructures for family presence, and to train staff to respond to the information and emotional needs of families. DISCUSSION Translating a family nursing framework into clinical practice involves the need for reassessing educational and management policies in clinical contexts. CONCLUSION This research brings new understanding about the attitudes of some Brazilian nurses and physicians on the implementation of family presence during resuscitation and identifies the need to develop policies and strategies to improve family presence in emergency departments. IMPLICATIONS FOR NURSING AND HEALTH POLICY Hospital-based policies are required to improve family-centred care in emergency departments while providing a criterion of legality and safety to professionals to invite families to be present during invasive procedures. Also, family-focused education in health science degrees, continuing education and in the community is required.

Abstract
BACKGROUND Objective structured clinical examinations (OSCEs) are designed to assess clinical skill performance and competency of students in preparation for 'real world' clinical responsibilities. OSCEs are commonly used in health professional education and are typically associated with high levels of student anxiety, which may present a significant barrier to performance. Students, including nursing students, have identified that flexible access to exemplar OSCEs might reduce their anxiety and enable them to better prepare for such examinations. AIM To implement and evaluate an innovative approach to preparing students for OSCEs in an undergraduate (registration) acute care nursing course. METHOD A set of digitized OSCE exemplars were prepared and embedded in the University-based course website as part of usual course learning activities. Use of the exemplars was monitored, pre and post OSCE surveys were conducted, and qualitative data were collected to evaluate the approach. OSCE grades were also examined. FINDINGS The online OSCE exemplars increased self-rated student confidence, knowledge, and capacity to prepare and provided clarity around assessment expectations. OSCE exemplars were accessed frequently and positively received; but did not impact on performance. CONCLUSION Video exemplars aid student preparation for OSCEs, providing a flexible, innovative and clear example of the assessment process. Video exemplars improved self-rated student confidence and understanding of performance expectations, leading to increased engagement and reduced anxiety when preparing for the OSCE, but not overall OSCE performance. Such OSCE exemplars could be used to increase staff capacity and improve the quality of the student learning experience.

Abstract
OBJECTIVES Adrenergic receptor (ADR) genotypes have been associated with adverse outcomes in heart failure. Our objective was to evaluate the association of ADR genotypes with post-Norwood outcomes in infants with hypoplastic left heart syndrome (HLHS). METHODS Infants with HLHS participating in the Pediatric Heart Network Single-Ventricle Reconstruction Trial underwent genotyping for 4 single-nucleotide polymorphisms in 3 ADR genes: ADRB1_231A/G, ADRB1_1165G/C, ADRB2_5318C/G, and ADRA2A_2790C/T. The association of genotype with freedom from serious adverse events (SAEs) (death, transplant, extracorporeal membrane oxygenation, cardiopulmonary resuscitation, acute shunt failure, unplanned reoperations, or necrotizing enterocolitis) during 14 months' follow-up was assessed with Cox regression and the association with post-Norwood complications was assessed with Poisson regression. Models were adjusted for clinical and surgical factors. RESULTS The study included 351 eligible patients (62% male; 83% white). The mean age at Norwood procedure was 5.6 ± 3.6 days. A total of 152 patients had SAEs during 14-month follow-up including 84 deaths and 10 transplants. ADRA2A_2790CC genotype had lower SAE-free survival compared with CT/TT genotypes during follow-up (Log rank test, P = .02), and this association was independent of clinical and surgical risk factors (adjusted Cox regression, hazard ratio 1.54 [95% confidence interval 1.04, 2.30] P = .033). Post-Norwood complication rate did not differ by genotype. CONCLUSIONS Infants with HLHS harboring ADR genotypes that are associated with greater catecholamine release or sensitivity had lower event-free survival after staged palliation. Excess catecholamine activation may adversely affect cardiovascular adaptation after the Norwood procedure. Future studies should explore whether targeting adrenergic activation in those harboring risk genotypes can improve outcomes. (ClinicalTrials.gov number NCT00115934).

Abstract
The effect of moderate restriction of pre- and peri-pubertal liveweight gain on puberty attainment and potential litter size was investigated. At 69 days of age, 48 Large White/Landrace crossbred gilts (28.3 ± 0.3 kg), were fed to attain a liveweight of 70 kg (LIGHT) or 100 kg (HEAVY) at 161 days of age (n = 24 gilts/treatment). At 161 days of age, half the gilts in each group were fed to gain liveweight at 0.5 (LOW) or 1.0 (HIGH) kg/day until puberty (n = 12 gilts/treatment). From 175 days of age, gilts received 20 min/day of full, physical boar contact. Gilts were artificially inseminated at the pubertal oestrus, with reproductive tracts collected 22 ± 0.1 days later, and the number of corpora lutea and viable embryos recorded. LIGHT-LOW gilts were older (P < 0.05) at puberty compared with LIGHT-HIGH, HEAVY-LOW and HEAVY-HIGH gilts; 207.7 ± 3.50 versus 191.7 ± 3.65, 193.1 ± 3.50 and 192.5 ± 3.65, respectively. Treatment (HIGH vs LOW) increased (P < 0.05) pubertal ovulation rate (15.2 ± 0.43 vs 13.1 ± 0.47), oestradiol at oestrus (13.4 ± 1.87 vs 9.1 ± 1.22 pg/mL) and progesterone 72 h post-oestrus (7.1 ± 0.48 vs 4.6 ± 0.50 ng/mL). Embryo number (10.8 ± 0.46) and survival (77.0 ± 3.21) were unaffected (P > 0.05) by treatment. To conclude, puberty was delayed by chronic, but not acute, dietary restriction. Although short-term, moderate increases in feed intake increased pubertal ovulation rates, embryo numbers and survival were unaffected.

Abstract
244 undergraduates read a transcript of a murder case, then made recommendations for treatment of the offender. In Exp. 1, length of sentence for a convicted murderer was unrelated to his mode of attire. In Exp. 2, sentences were unrelated to intention but were longer with than without a motive. In Exp. 3, punishment was not consistently related to the victim's gender. Suggestions for research are given.

Abstract
The study was conducted to evaluate the thermophysiological, haematological, biochemical and behavioural stress responses of sheep transported on road. A total of 44 Chamarita breed adult ewes were randomly allotted to one of two groups, one control group (untransported) and transported group (journey of 4 h), and blood stress indicators were measured 1 day before transport and at four time points post-transport (0, 4 and 24 h). Thermophysiological profiles of ewes were measured by temperature buttons (iButton Thermochron® ) and placed in intravaginal sponges. Direct observations, with a combination of scan and behaviour sampling, were carried out to collect information on individual behaviour and the time it took the ewes to drink water, eat and rest after returning to their pen respectively. Transported ewes lost approximately 1 kg live weight compared to controls and had higher body temperatures until 12 h post-transport. Cortisol, glucose, non-esterified fatty acid (NEFA) concentrations as well as the neutrophil-lymphocyte ratio (N/L) and other physiological indicators were higher immediately after unloading in transported ewes but mostly returned to normal after 4 h, with complete recovery after 24 h. Behavioural analysis post-transport demonstrated that transported ewes chose to eat before drinking and spent less time resting than controls in the first 3 h after unloading. The study demonstrates that transportation even under short-journey conditions induced behavioural, physiological and thermophysiological responses indicative of the induction of significant stress, leading to live weight shrinkage that may jeopardize farmer's incomes. Finally, results of this study validated the use of iButton Thermochron® data loggers for monitoring the stress response during transport.

Genome wide transcriptomic analysis identifies pathways affected by the infusion of Clostridium perfringens culture supernatant in the duodenum of broilers in situ. J Anim Sci 2016; 93:3152-63.

Abstract
Clostridium perfringens type A is the main etiological factor for necrotic enteritis, a multifactorial enteric disease that penalizes performance, health, and welfare of poultry. Lack of knowledge of host responses and disease pathogenesis is slowing down progress on developing therapies for disease control. A combined genomewide and targeted gene approach was used to investigate pathways and biological functions affected by the infusion of C. perfringens culture supernatant in the duodenum of broilers in 2 experiments. An in situ isolated loop of duodenum was prepared in anesthetized broilers of 3 wk of age (Exp. 1) and was infused either with crude C. perfringens culture supernatant (n = 7; treated), positive for necrotic enteritis B-like toxin (NetB) as determined by a cytotoxicity assay, or with a control preparation (n = 6; control). Birds were maintained alive for 1 h and then euthanized for tissue recovery. The use of the Affymetrix chicken genome array on RNA samples from loop tissue showed top biological functions affected by culture supernatant infusion included cell morphology, immune cell trafficking, and cell death; pathways affected included death receptor signaling, inflammatory response, and nuclear factor (NF)-κB signaling. In a second in situ study (Exp. 2), broilers were maintained alive for 4 h to monitor temporal expression patterns of targeted genes. Duodenal tissue was removed at 0.5, 1, 2, and 4 h post-infusion with culture supernatant (n = 9) or a control preparation (n = 5) for histology and gene expression analysis. Genes encoding proinflammatory cytokines, such as interferon γ (IFNγ), cell trafficking, such as neuroblastoma 1 (NBL1) and B cell CLL/Lymphoma 6 (BCL6), and cell death, such as Fas cell surface death receptor (FAS) and GTPase IMAP family member 8 (GIMAP8), were differentially expressed in the duodenum of treated and control broilers (P < 0.05). We have demonstrated that C. perfringens culture supernatant (NetB positive) infusion resulted in histological and gene expression changes consistent with necrotic enteritis in the duodenum of broilers. In the absence of live bacteria, crude culture supernatant resulted in early immunomodulation, inflammation, and cell death in the duodenum. The pathways identified here can be targeted for the development of new drugs, vaccines, and novel therapies for necrotic enteritis in broilers.

Cytokine, catabolic enzyme and structural matrix gene expression in synovial fluid following intra-articular administration of triamcinolone acetonide in exercised horses. Equine Vet J 2016; 49:107-115. [PMID: 26518341 DOI: 10.1111/evj.12531] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2014] [Accepted: 10/17/2015] [Indexed: 01/07/2023]
Abstract
REASON FOR PERFORMING STUDY The frequent use of intra-articular triamcinolone acetonide (TA) in performance horses warrants further study of the duration of as well as the beneficial and detrimental effects on gene expression associated with administration. OBJECTIVES To assess the effects of intra-articular administration of TA on the expression of selected anti- and proinflammatory and structural matrix genes following its administration into joints of exercised Thoroughbred horses and to correlate these effects with plasma and synovial fluid drug concentrations. STUDY DESIGN Block design experiment. METHODS Eight exercised horses received a single intra-articular administration of 9 mg of TA. Synovial fluid samples were collected from the treated and contralateral joints prior to and up to 49 days following drug administration. Microarray and quantitative reverse transcription polymerase chain reaction analysis were used to assess changes in expression levels of various inflammatory and structural genes post drug administration. RESULTS Drug concentrations in plasma and synovial fluid, were no longer quantifiable by 6 and 28 days following drug administration respectively. In total, the expression level of 5490 genes were significantly altered on micro array analysis, following intra-articular TA administration. Of the genes selected for further study by quantitative reverse transcription polymerase chain reaction analysis, significant changes in inflammatory genes (annexin type 1, cyclooxygenase-1 and tumour necrosis factor stimulated gene 6) and structural genes (collagen and aggrecan) were noted. CONCLUSIONS This study supports the use of synovial fluid as a biological matrix for studying the effects of corticosteroids on gene expression. For the majority of genes studied the effects on expression relative to baseline for both inflammatory and matrix genes were prolonged relative to plasma and synovial fluid TA concentrations. Downregulation of collagen gene expression warrants the careful use of TA in horses.
