COVID-19 Stroke Apical Lung Examination Study 2: a national prospective CTA biomarker study of the lung apices, in patients presenting with suspected acute stroke (COVID SALES 2). Neuroimage Clin 2024; 42:103590. [PMID: 38513535 DOI: 10.1016/j.nicl.2024.103590] [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: 01/26/2024] [Revised: 03/10/2024] [Accepted: 03/13/2024] [Indexed: 03/23/2024]
Abstract
BACKGROUND Apical ground-glass opacification (GGO) identified on CT angiography (CTA) performed for suspected acute stroke was developed in 2020 as a coronavirus-disease-2019 (COVID-19) diagnostic and prognostic biomarker in a retrospective study during the first wave of COVID-19. OBJECTIVE To prospectively validate whether GGO on CTA performed for suspected acute stroke is a reliable COVID-19 diagnostic and prognostic biomarker and whether it is reliable for COVID-19 vaccinated patients. METHODS In this prospective, pragmatic, national, multi-center validation study performed at 13 sites, we captured study data consecutively in patients undergoing CTA for suspected acute stroke from January-March 2021. Demographic and clinical features associated with stroke and COVID-19 were incorporated. The primary outcome was the likelihood of reverse-transcriptase-polymerase-chain-reaction swab-test-confirmed COVID-19 using the GGO biomarker. Secondary outcomes investigated were functional status at discharge and survival analyses at 30 and 90 days. Univariate and multivariable statistical analyses were employed. RESULTS CTAs from 1,111 patients were analyzed, with apical GGO identified in 8.5 % during a period of high COVID-19 prevalence. GGO showed good inter-rater reliability (Fleiss κ = 0.77); and high COVID-19 specificity (93.7 %, 91.8-95.2) and negative predictive value (NPV; 97.8 %, 96.5-98.6). In subgroup analysis of vaccinated patients, GGO remained a good diagnostic biomarker (specificity 93.1 %, 89.8-95.5; NPV 99.7 %, 98.3-100.0). Patients with COVID-19 were more likely to have higher stroke score (NIHSS (mean +/- SD) 6.9 +/- 6.9, COVID-19 negative, 9.7 +/- 9.0, COVID-19 positive; p = 0.01), carotid occlusions (6.2 % negative, 14.9 % positive; p = 0.02), and larger infarcts on presentation CT (ASPECTS 9.4 +/- 1.5, COVID-19 negative, 8.6 +/- 2.4, COVID-19 positive; p = 0.00). After multivariable logistic regression, GGO (odds ratio 15.7, 6.2-40.1), myalgia (8.9, 2.1-38.2) and higher core body temperature (1.9, 1.1-3.2) were independent COVID-19 predictors. GGO was associated with worse functional outcome on discharge and worse survival after univariate analysis. However, after adjustment for factors including stroke severity, GGO was not independently predictive of functional outcome or mortality. CONCLUSION Apical GGO on CTA performed for patients with suspected acute stroke is a reliable diagnostic biomarker for COVID-19, which in combination with clinical features may be useful in COVID-19 triage.

Gracilis muscle interposition for pouch-vaginal fistulas: a single-centre cohort study and literature review. Tech Coloproctol 2023; 28:7. [PMID: 38079014 DOI: 10.1007/s10151-023-02880-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/04/2023] [Accepted: 11/16/2023] [Indexed: 12/18/2023]
Abstract
BACKGROUND First described by Parks and Nicholls in 1978, the ileal pouch-anal anastomosis (IPAA) has revolutionized the treatment of mucosal ulcerative colitis (MUC) and familial adenomatous polyposis (FAP). IPAA is fraught with complications, one of which is pouch-vaginal fistulas (PVF), a rare but challenging complication noted in 3.9-15% of female patients. Surgical treatment success approximates 50%. Gracilis muscle interposition (GMI) is a promising technique that has shown good results with other types of perineal fistulas. We present the results from our institution and a comprehensive literature review. METHODS A retrospective observational study including all patients with a PVF treated with GMI at our institution from December 2018-January 2000. Primary outcome was complete healing after ileostomy closure. RESULTS Nine patients were included. Eight of nine IPAAs (88.9%) were performed for MUC, and one for FAP. A subsequent diagnosis of Crohn's disease was made in five patients. Initial success occurred in two patients (22.2%), one patient was lost to follow-up and seven patients, after further procedures, ultimately achieved healing (77.8%). Four of five patients with Crohn's achieved complete healing (80%). CONCLUSION Surgical healing rates quoted in the literature for PVFs are approximately 50%. The initial healing rate was 22.2% and increased to 77.8% after subsequent surgeries, while it was 80% in patients with Crohn's disease. Given this, gracilis muscle interposition may have a role in the treatment of pouch-vaginal fistulas.

Abstract
INTRODUCTION Colorectal operations such as an extra-levator abdominoperineal (elAPE) excision for locally advanced or recurrent cancer create a significant perineal tissue deficit. Options for perineal reconstruction include bilateral pedicled gracilis muscle flaps (BPGMF). Fashioning the gracili into a 'weave' creates a muscular sling that supports pelvic contents and is a novel technique. Our series reports the outcomes of the BPGMF in 50 patients undergoing surgery for pelvic cancer. METHOD This is a retrospective, single-centre study of patients undergoing reconstruction of perineal defects using BPGMF. All surgeries took place between January 2008 and February 2021. The primary outcome measured was perineal wound healing. The secondary outcomes measured were complications of surgical sites and length of hospital stay (short term), flap integrity on follow-up imaging and functional outcomes (long term). RESULTS Fifty patients underwent perineal reconstruction using BPGMF (26 males). The median age was 62 years. The 30-day mortality was 2% (n = 1). The average follow-up period was 2 years. Complete perineal wound healing was 86% (42/49) at outpatient follow-up. Complication rates for the donor site and reconstructed site were 14% and 22%, respectively. Complications included infection (2% donor site, 12% perineum), haematoma (4% donor site), dehiscence (2% donor site, 4% perineum) and seroma (3% donor site, 2% perineum). CONCLUSION BPGMF offers a reliable and technically simple muscle flap to reconstruct large perineal defects. The muscle flap integrity appears maintained on follow-up imaging despite a lack of flap monitoring tools. This cohort had minimal functional impairment following BPGMF.

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.

Post-acute COVID syndrome (long COVID): What should radiographers know and the potential impact for imaging services. Radiography (Lond) 2022; 28 Suppl 1:S93-S99. [PMID: 36109264 PMCID: PMC9468096 DOI: 10.1016/j.radi.2022.08.009] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2022] [Revised: 07/30/2022] [Accepted: 08/22/2022] [Indexed: 11/30/2022]
Abstract
Objectives The COVID-19 pandemic caused an unprecedented health crisis resulting in over 6 million deaths worldwide, a figure, which continues to grow. In addition to the excess mortality, there are individuals who recovered from the acute stages, but suffered long-term changes in their health post COVID-19, commonly referred to as long COVID. It is estimated there are currently 1.8 million long COVID sufferers by May 2022 in the UK alone. The aim of this narrative literature review is to explore the signs, symptoms and diagnosis of long COVID and the potential impact on imaging services. Key findings Long COVID is estimated to occur in 9.5% of those with two doses of vaccination and 14.6% if those with a single dose or no vaccination. Long COVID is defined by ongoing symptoms lasting for 12 or more weeks post acute infection. Symptoms are associated with reductions in the quality of daily life and may involve multisystem manifestations or present as a single symptom. Conclusion The full impact of long COVID on imaging services is yet to be realised, but there is likely to be significant increased demand for imaging, particularly in CT for the assessment of lung disease. Educators will need to include aspects related to long COVID pathophysiology and imaging presentations in curricula, underpinned by the rapidly evolving evidence base. Implications for practice Symptoms relating to long COVID are likely to become a common reason for imaging, with a particular burden on Computed Tomography services. Planning, education and updating protocols in line with a rapidly emerging evidence base is going to be essential.

Abstract
BACKGROUND The REGAIN (Regional versus General Anesthesia for Promoting Independence after Hip Fracture) trial found similar ambulation and survival at 60 days with spinal versus general anesthesia for hip fracture surgery. Trial outcomes evaluating pain, prescription analgesic use, and patient satisfaction have not yet been reported. OBJECTIVE To compare pain, analgesic use, and satisfaction after hip fracture surgery with spinal versus general anesthesia. DESIGN Preplanned secondary analysis of a pragmatic randomized trial. (ClinicalTrials.gov: NCT02507505). SETTING 46 U.S. and Canadian hospitals. PARTICIPANTS Patients aged 50 years or older undergoing hip fracture surgery. INTERVENTION Spinal or general anesthesia. MEASUREMENTS Pain on postoperative days 1 through 3; 60-, 180-, and 365-day pain and prescription analgesic use; and satisfaction with care. RESULTS A total of 1600 patients were enrolled. The average age was 78 years, and 77% were women. A total of 73.5% (1050 of 1428) of patients reported severe pain during the first 24 hours after surgery. Worst pain over the first 24 hours after surgery was greater with spinal anesthesia (rated from 0 [no pain] to 10 [worst pain imaginable]; mean difference, 0.40 [95% CI, 0.12 to 0.68]). Pain did not differ across groups at other time points. Prescription analgesic use at 60 days occurred in 25% (141 of 563) and 18.8% (108 of 574) of patients assigned to spinal and general anesthesia, respectively (relative risk, 1.33 [CI, 1.06 to 1.65]). Satisfaction was similar across groups. LIMITATION Missing outcome data and multiple outcomes assessed. CONCLUSION Severe pain is common after hip fracture. Spinal anesthesia was associated with more pain in the first 24 hours after surgery and more prescription analgesic use at 60 days compared with general anesthesia.

P-368 Serum progesterone on the day of embryo transfer in stimulated cycles does not correlate with pregnancy outcomes. Hum Reprod 2022.

Abstract
Abstract
Study question
Is the chance of positive hCG, clinical pregnancy or live birth in a fresh embryo transfer (ET) IVF cycle, affected by day of transfer serum progesterone (P4) level?
Summary answer
There is no correlation between P4 level on the day of ET and pregnancy outcomes.
What is known already
Data from studies of frozen–thawed embryo transfer cycles suggest that low as well as high P4 levels during the mid-luteal phase may decrease the chance of pregnancy. The altered P4 pattern may disrupt the endometrial maturation leading to asynchrony between embryonic development and endometrial receptivity, thereby, compromising implantation and early development of pregnancy.
Study design, size, duration
A monocentric retrospective study of prospectively collected data, of women undergoing IVF or ICSI treatment July 2019-July 2020, and having a fresh day 5 single embryo transfer (SET). 825 first and second stimulation cycles were included. Patients underwent a GnRH-antagonist protocol and were triggered for final oocyte maturation with hCG (OvidrelR). All patients received vaginal luteal support. The study population was unselected, treated with the unit’s usual stimulation protocols, representing an everyday patient cohort.
Participants/materials, setting, methods
Serum P4 levels on the day of ET were correlated with positive hCG, clinical pregnancy (CP) and live birth (LB) rates. Based on previously defined P4 thresholds, patients were divided into four P4 groups based on serum levels (P4<150 nmol/l, P4 150–250 nmol/l, P4 251–400 nmol/l and P4>400 nmol/l). The data was further interrogated using additional P4 cut offs, to confirm that there were no discernible differences based on P4 levels.
Main results and the role of chance
There was no level of P4 below or above which the chance of pregnancy was consistently reduced. The chance of a positive hCG-test in the whole cohort was 51%, (95% CI: 47.1-54) following blastocyst transfer and was not different across the four groups (50, 48.2, 51.1, 52%, P = 0.88). Likewise, there was no difference in CP 41.8% (CI 38.4-45.3%) and LB 30.4% (27.3-33.7%), between the four groups. No negative association between P4 and chance of pregnancy when the other thresholds, described above, were applied. All estimates were adjusted for maternal age, maternal BMI, eggs retrieved and number of eggs fertilised, with the outcome remaining unchanged.
Limitations, reasons for caution
The finding of no difference in pregnancy outcomes across P4 ranges in this study, only applies to fresh blastocyst transfer IVF cycles, using hCG trigger and vaginal LPS, and should be corroborated in future clinical trials. Also, there is possible inaccuracy in P4 levels due to diurnal variability.
Wider implications of the findings
Future studies are necessary to explore the diurnal variability, and its possible contribution to these results.

A systematic review of pharmacist-led audit and feedback interventions to influence prescribing behaviour in general practice settings. INTERNATIONAL JOURNAL OF PHARMACY PRACTICE 2021.

Abstract
Abstract
Introduction
Audit and Feedback (A&F) involves measuring data about practice, comparing it with clinical guidelines, professional standards or peer performance, and then feeding back the data to individuals/groups of health professionals to encourage change in practice (if required). A 2012 Cochrane review (1) found A&F was effective in changing health professionals’ behaviour and suggested that the person who delivers the A&F intervention influences its effect. Increasingly, pharmacists work in general practice and often have responsibility for medication review and repeat prescriptions. The effectiveness of pharmacist-led A&F in influencing prescribing behaviour is uncertain.
Aim
This secondary analysis from an ongoing update of the original Cochrane review aims to identify and describe pharmacist-led A&F interventions and evaluate their impact on prescribing behaviour in general practice compared with no intervention.
Methods
This sub-review is registered with PROSPERO: CRD42020194355 and complies with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (2). For the updated Cochrane review, the Cochrane Effective Practice and Organization of Care Group searched MEDLINE (1946 to present), EMBASE, CINAHL and Cochrane Library (March 2019) to identify randomised trials featuring A&F interventions. For this sub-review, authors screened titles and abstracts (May 2020) to identify trials involving pharmacist-led A&F interventions in primary care, extracted data, and assessed risk of bias (RoB) in eligible studies. Review results are summarised descriptively. Heterogeneity will be assessed and a random-effects meta-analysis is planned. Publication bias for selected outcomes and the certainty of the body of evidence will be evaluated and presented. Sub-group analyses will be conducted.
Results
Titles and abstracts of 295 studies identified for inclusion in the Cochrane A&F review update were screened. Eleven studies (all cluster-randomised trials) conducted in 9 countries (Denmark, Italy, Netherlands, Norway, Republic of Ireland, UK, Australia, Malaysia, USA) were identified for inclusion (Figure 1). Six studies had low RoB, two had high risk due to dissimilarities between trial arms at baseline and/or insufficient detail about randomisation, and three studies had unclear RoB. Studies examined the effect of A&F on prescribing for specific conditions (e.g. hypertension), medications (e.g. antibiotics), populations (e.g. patients >70), and prescribing errors (e.g. inappropriate dose). The pharmacist delivering A&F was a colleague of intervention participants in five studies. Pharmacists’ levels of skill and experience varied; seven studies reported details of pharmacist training undertaken for trial purposes. A&F interventions in nine studies demonstrated changes in prescribing, including reductions in errors or inappropriate prescribing according to the study aims and smaller increases in unwanted prescribing compared with the control group. Data analyses are ongoing (results will be available for the conference).
Conclusion
The preliminary results demonstrate the effectiveness of pharmacist-led A&F interventions in different countries and health systems with influencing prescribing practice to align more closely with guidance. Studies measured different prescribing behaviours; meta-analysis is unlikely to include all 11 studies. Further detailed analysis including feedback format/content/frequency and pharmacist skill level/experience, work-base (external/internal to recipients), will examine the impact of specific features on intervention effectiveness.

Abstract
Abstract
Background
Diffusion Tensor Cardiovascular Magnetic Resonance (DT-CMR) can quantify metrics of tissue integrity (mean diffusivity [MD] and fractional anisotropy [FA]) and changes in laminar microstructures (sheetlets), which reorientate from more wall-parallel in diastole (DIA) towards wall-perpendicular in systole (SYS) as the myocardium thickens, quantified by E2 angle [E2A]. Microstructural changes after STEMI may provide new insights into adverse LV remodelling and risk stratification.
Methods
In vivo DT-CMR was performed 3–5 days after PPCI for first presentation STEMI (N=19, mean age 57±9, 79% male). DT-CMR was acquired in 2 short-axes (SYS & DIA) using a STEAM-EPI sequence. 12 segment analysis of MD, FA, E2A and E2A mobility (ΔE2A = E2ASYS − E2ADIA) was performed. Infarct (INF) segments were defined as >25% LGE, adjacent (ADJ, located contiguous to INF) and remote (REM, all other segments). Wilcoxon signed rank tests were used with threshold P<0.017 (Bonferroni corrected).
Results
See Table.
MD in both SYS and DIA was significantly higher in INF and ADJ regions compared to REM. FA in both SYS and DIA was lower in the INF and ADJ compared to REM. E2ADIA was higher in INF, indicating a more wall-perpendicular orientation of sheetlets, compared to ADJ and REM zones. E2ASYS in INF was significantly reduced, indicating a more wall-parallel orientation of sheetlets, compared to ADJ and REM regions, resulting in significantly reduced sheetlet mobility (ΔE2A).
Conclusions
Microstructural changes can be detected after acute STEMI by in vivo DT-CMR. Zonal changes in MD and FA may suggest loss of barriers to water diffusion and altered cardiomyocyte organisation, respectively. We provide the first report of reduced sheetlet mobility after acute STEMI in INF. Ongoing work is evaluating the mechanisms and prognostic importance of altered sheetlet mobility after STEMI.

Abstract
STUDY QUESTION What is the evidence to guide the management of women who wish to conceive following abdominopelvic radiotherapy (AP RT) or total body irradiation (TBI)? SUMMARY ANSWER Pregnancy is possible, even following higher doses of post-pubertal uterine radiation exposure; however, it is associated with adverse reproductive sequelae and pregnancies must be managed in a high-risk obstetric unit. WHAT IS KNOWN ALREADY In addition to primary ovarian insufficiency, female survivors who are treated with AP RT and TBI are at risk of damage to the uterus. This may impact on its function and manifest as adverse reproductive sequelae. STUDY DESIGN SIZE DURATION A review of the literature was carried out and a multidisciplinary working group provided expert opinion regarding assessment of the uterus and obstetric management. PARTICIPANTS/MATERIALS SETTING METHODS Reproductive outcomes for postpubertal women with uterine radiation exposure in the form of AP RT or TBI were reviewed. This included Pubmed listed peer-reviewed publications from 1990 to 2019, and limited to English language.. MAIN RESULTS AND THE ROLE OF CHANCE The prepubertal uterus is much more vulnerable to the effects of radiation than after puberty. Almost all available information about the impact of radiation on the uterus comes from studies of radiation exposure during childhood or adolescence.An uncomplicated pregnancy is possible, even with doses as high as 54 Gy. Therefore, tumour treatment doses alone cannot at present be used to accurately predict uterine damage. LIMITATIONS REASONS FOR CAUTION Much of the data cannot be readily extrapolated to adult women who have had uterine radiation and the publications concerning adult women treated with AP RT are largely limited to case reports. WIDER IMPLICATIONS OF THE FINDINGS This analysis offers clinical guidance and assists with patient counselling. It is important to include patients who have undergone AP RT or TBI in prospective studies to provide further evidence regarding uterine function, pregnancy outcomes and correlation of imaging with clinical outcomes. STUDY FUNDING/COMPETING INTERESTS This study received no funding and there are no conflicts of interest. TRIAL REGISTRATION NUMBER N/A.

Abstract
OBJECTIVE To estimate the prevalence and incidence of endometriosis among Australian women. DESIGN Population-based cohort study linked to administrative health records. SETTING Secondary analysis of seven surveys collected between 2000 and 2018 from a population-based cohort study. POPULATION A total of 13 508 Australian women, born 1973-78, from a prospective cohort study of 14 247 women conducted between 1996 and 2018. METHODS During 2000 and 2018, self-reported longitudinal survey data were linked to three administrative health databases to separately identify women with clinically confirmed or suspected endometriosis across the multiple data sources. MAIN OUTCOME MEASURES Prevalence and incidence of clinically confirmed endometriosis in the cohort were first estimated using national hospital data. Data were then combined with other administrative health databases and the survey data to capture all clinically confirmed and suspected diagnoses of endometriosis. RESULTS The cumulative prevalence of clinically confirmed endometriosis was 6.0% (95% CI 5.8-6.2%) by age 40-44 years. The cumulative prevalence increased to 11.4% (95% CI 11.1-11.7%) when adding diagnoses of clinically suspected endometriosis. Age-specific incidence estimates peaked to 6 per 1000 person-years at age 30-34 years. CONCLUSIONS Among 13 508 Australian women followed for 20 years, one in nine women had clinically confirmed or suspected endometriosis by the age of 44, with most diagnosed during their early thirties. Endometriosis is a significant public health issue requiring increased surveillance, clinical awareness and management. Efforts to expand knowledge on the aetiology of the disease and optimal methods for disease management are crucial to women's health. TWEETABLE ABSTRACT In a national study of 13 508 Australian women, one in nine women were diagnosed with endometriosis by age 44.

Abstract
Background:Arthritis often leads to presenteeism (decreased at-work productivity), missed days from work and permanent work disability, leading to reduced quality of life and high costs to individuals and society. Yet, health services addressing the employment needs of people with arthritis are lacking.Objectives:We evaluated the effectiveness of the Making-it-WorkTM(MiW) program, an online self-management program developed to help people with inflammatory arthritis (IA) deal with employment issues.Methods:A multi-center RCT evaluated the effectiveness of MiW at improving presenteeism and preventing work cessation (WC) over two years. Participants were recruited from rheumatologist practices, consumer organizations and arthritis programs, in three Canadian provinces. Eligibility criteria: diagnosis of IA, employed, age 18-59, and concerned about ability to work. Participants were randomized 1:1 to MiW or usual care plus printed material on workplace tips. MiW consists of five online self-learning modules and group meetings, and individual vocational counselling and ergonomic consultations. Questionnaires were administered every 6 months. Outcomes were presenteeism [Rheumatoid Arthritis Work Instability Scale (RA-WIS)], time to WC ≥ 6 months, and time to WC ≥ 2 months (secondary outcome). Baseline characteristics (age, gender, ethnicity, occupation, education, disease duration and self-employment) were collected. Intention-to-treat (ITT) longitudinal analysis of RA-WIS using linear mixed effect regression models with 2-year comparison as primary endpoint and survival analysis for time to WC using Kaplan-Meier and Cox Proportional Hazard models were performed. Robustness analyses were conducted by using various missing values imputation methods like last observation carried forward, imputation using worse possible outcomes and model-based multiple imputations; using square root transformation of RA-WIS outcome; and adjusting for baseline covariates. SAS version 9.4 was used.Results:A total of 564 participants were recruited, with 478 (84.75%) completing 2-year follow-up. Baseline characteristics were similar between groups. Mean RA-WIS scores were significantly lower in the intervention group from 6 months onwards, with the greatest difference observed at 2 years (-1.78, 95%CI: -2.7, -0.9, p < .0001), yielding a standardized effect size of 32%. Satisfactory robustness was observed. Work cessation occurred less often in intervention than control groups, but only reached statistical significance for WC ≥ 2 months (WC ≥ 6 months: 31 versus 44 events, aHR 0.70, 95%CI: 0.44, 1.11, p = 0.13; WC ≥ 2 months: 39 versus 61 events, aHR: 0.65, 95%CI: 0.43, 0.98, p = 0.04).Conclusion:Results of the RCT reveal the program was effective at improving presenteeism and preventing short-term WC. Effectiveness at preventing long-term work disability will be assessed at 5 years. This program fills one of the most important and costly unmet needs for people with inflammatory arthritis.References:[1]Carruthers EC, Rogers P, Backman CL, et al. “Employment and arthritis: making it work” a randomized controlled trial evaluating an online program to help people with inflammatory arthritis maintain employment (study protocol).BMC Med Inform Decis Mak. 2014;14:59.

Abstract
Abstract
A simple, 10-min immunoassay system has been developed that simultaneously screens for five different classes of drugs of abuse in a urine sample. This system tests for amphetamines, cannabinoids, cocaine metabolites, opiates, and phencyclidine, and each assay has a specific preset cutoff concentration. Accuracy is > 99% for reporting positive or negative results for samples with 200% or 50%, respectively, of the cutoff concentrations of the drugs. Tests of a panel of 96 compounds yielded only three cases of nonspecific reactivity (at a drug concentration of 100 mg/L). Another panel of 12 compounds that could normally be found in urine samples was also evaluated and no interferences were observed. Concordance was > 95% between this system and the comparable automated immunoassays for detecting drugs of abuse. Greater than 98% of GC/MS-confirmed positive samples gave positive results with this assay system.

Abstract
Abstract
Test portions from 3 environmental surface types, representative of typical surfaces found in a food production facility, were analyzed by the Visual Immunoprecipitate assay (VIP®) and the U.S. Department of Agriculture/Food Safety and Inspection Service (USDA/FSIS) culture method for Listeria monocytogenes and related Listeria species. In all cases, naturally contaminated environmental test samples were collected from an actual food production facility by sponge or swab. Test samples from concrete surfaces were collected by both swab and sponge; sponge test samples were collected from rubber surfaces, and swabs were used to sample steel surfaces. Test portions from each surface type were simultaneously analyzed by both methods. A total of 27 laboratories, representing government agencies as well as private industry in both the United States and Canada, participated in the study. During this study, a total of 615 test portions and controls was analyzed and confirmed, of which 227 were positive and 378 were negative by both methods. Nine test portions were positive by culture, but negative by the VIP. Five test portions were negative by culture, but positive by the VIP. Four test portions were negative by VIP and by culture, but confirmed positive when VIP enrichment broths were subcultured to selective agars. The data reported here indicate that the VIP method and the USDA/FSIS culture method are statistically equivalent for detection of L. monocytogenes and related Listeria species from environmental surfaces taken by sponges or swabs.

Abstract
OBJECTIVES Anthrax is a disease with an age old history in Africa caused by the Gram-positive endospore forming soil bacterium Bacillus anthracis. Epizootics of wild ungulates occur annually in the enzootic region of Pafuri, Kruger National Park (KNP) in the Limpopo Province of South Africa. Rigorous routine surveillance and diagnostics in KNP, has not revealed these rare isolates since the 1990s, despite unabated annual outbreaks. In 2011 a cheetah was diagnosed as anthrax positive from a private game reserve in Limpopo Province and reported to State Veterinary Services for further investigation. Isolation, molecular diagnostics, whole genome sequencing and comparative genomics were carried out for B. anthracis KC2011. RESULTS Bacteriological and molecular diagnostics confirmed the isolate as B. anthracis. Subsequent typing and whole genome single nucleotide polymorphisms analysis indicated it clustered alongside B. anthracis SA A0091 in the B.Br.010 SNP branch. Unlike B. anthracis KrugerB strain, KC2011 strain has unique SNPs and represents a new branch in the B-clade. The isolation and genotypic characterisation of KC2011 demonstrates a gap in the reporting of anthrax outbreaks in the greater Limpopo province area. The identification of vulnerable and susceptible cheetah mortalities due to this strain has implications for conservation measures and disease control.

Abstract
BACKGROUND Biosimilar infliximab became available in the UK in 2015. Paediatric experience to date on its use is limited. We prospectively evaluated the safety and efficacy of biosimilar infliximab (Remsima) in two paediatric gastroenterology networks in patients with inflammatory bowel disease. METHODS Prospective clinical data were collected from laboratory reports, electronic patient records and case notes of 40 patients starting Remsima for the first time. Disease activity scores together with blood and stool biomarkers were used to assess response. RESULTS Our data set highlights that Remsima was associated with a significant clinical and biochemical improvement (p<0.01 or less for all parameters assessed) in Crohn's disease post induction. There were no significant safety issues noted. The total cost saving was £47 800, representing a 38% reduction from originator. CONCLUSION We found that biosimilar infliximab is as effective as originator infliximab and its use is associated with significant cost savings.

Abstract
Purpose: To describe a technique for common iliac artery (CIA) access during endovascular aortic aneurysm repair when unfavorable angulation between the CIA and the delivery sheath precludes direct arterial access. Technique: After retroperitoneal exposure of the CIA, a puncture site is chosen inferolateral to the surgical incision, and an 18-G trocar/cannula is advanced in alignment with the CIA through the anterior abdominal wall or skin of the upper thigh into the retroperitoneal space. Serial dilatation is performed over a guidewire placed through the cannula to create the subcutaneous tract. The trocar/cannula is replaced over the wire, and the CIA is punctured under direct vision. The guidewire is then advanced into the proximal aorta. A CIA arteriotomy is performed and the delivery system introduced over the guidewire through the tunnel into the iliac artery. Conclusions: Retroperitoneal exposure of the CIA with tunneled transabdominal wall delivery of the stent-graft avoids both external iliac artery injury and creation of a temporary access conduit in patients with iliac tortuosity and/or occlusive disease.

Abstract
Adolescents and young adults (ayas) with cancer in active treatment face a number of barriers to optimal care. In the present article, we focus on the 3 critical domains of care for ayas-medical, psychosocial, and research-and how changes to the system could overcome barriers. We summarize the current literature, outline recommended principles of care, raise awareness of barriers to optimal care, and suggest specific changes to the system to overcome those barriers in the Canadian context. Many of the recommendations can nevertheless be applied universally. These recommendations are endorsed by the Canadian Task Force on Adolescents and Young Adults with Cancer and build on outcomes from two international workshops held by that group.

Abstract
OBJECTIVES To identify from a patient's perspective, difficulties and differences in the comprehension of five global presenteeism measures in patients with inflammatory arthritis and OA across seven countries. METHODS Seventy patients with a diagnosis of inflammatory arthritis or OA in paid employment were recruited from seven countries across Europe and Canada. Patients were randomly allocated to be cognitively debriefed on 3/5 global measures [Work Productivity Scale - Rheumatoid Arthritis, Work Productivity and Activity Impairment Questionnaire (WPAI), Work Ability Index, Quality and Quantity questionnaire, and WHO Health and Work Performance Questionnaire (HPQ)], with the WPAI debriefed in all patients as a standard measure of comparison between countries and patients. NVivo was used to code the data into four themes: construct and anchor, time recall, reference frame, and attribution. RESULTS Discrepancies were found in the interpretation of the word performance (HPQ) between countries, with Romania and Sweden relating performance to sports rather than work. Seventy percent of patients considered that a 7-day recall (WPAI) can accurately represent how their disease affects work productivity. The compared to normal reference (Quality and Quantity questionnaire) was reportedly too ambiguous, and the comparison with colleagues (HPQ), made many feel uncomfortable. Overall, 29% of patients said the WPAI was the most relevant to them, making it the most favoured measure. CONCLUSION Overall, patients across countries agree that the construct of work productivity in the last 7 days can accurately reflect the impact of disease while at work. Some current constructs to assess at-work productivity are not interchangeable between languages.

Abstract
AIM To investigate how commonly valuable diagnostic information regarding the frontotemporal dementias (FTDs) may be missed on routine radiological reporting. MATERIALS AND METHODS The magnetic resonance imaging (MRI) examination results of a series of 39 consecutive patients in whom the diagnosis was initially thought to be a form of FTD were audited. Twenty-two patients satisfied formal diagnostic criteria for subtypes of FTD. The initial non-specialist radiological reports of the MRI examinations were compared with those of a radiologist who specifically examined the images for the possibility of atypical dementia. RESULTS Six of the 22 original reports provided a full and accurate description of the radiological findings, while two provided a fully accurate interpretation. CONCLUSION Valuable diagnostic information may be missed unless clinicians and radiologists jointly review and discuss brain imaging in cases of dementia. The use of standardised scales may enhance the reporting of MRI examinations for dementia.

Test-retest Reliability and Correlations of 5 Global Measures Addressing At-work Productivity Loss in Patients with Rheumatic Diseases. J Rheumatol 2015; 43:433-9.

Abstract
OBJECTIVE Several global measures to assess at-work productivity loss or presenteeism in patients with rheumatic diseases have been proposed, but the comparative validity is hampered by the lack of data on test-retest reliability and comparative concurrent and construct validity. Our objective was to test-retest 5 global measures of presenteeism and to compare the association between these scales and health-related well-being. METHODS Sixty-five participants with inflammatory arthritis or osteoarthritis in paid employment were recruited from 7 countries (UK, Canada, Netherlands, France, Sweden, Romania, and Italy). At baseline and 2 weeks later, 5 global measures of presenteeism were evaluated: the Work Productivity Scale-Rheumatoid Arthritis (WPS-RA), Work Productivity and Activity Impairment Questionnaire (WPAI), Work Ability Index (WAI), Quality and Quantity questionnaire (QQ), and the WHO Health and Performance Questionnaire (HPQ). Agreement between the 2 timepoints was assessed using single-measure intraclass correlations (ICC) and correlated between each other and with visual analog scale general well-being scores at followup by Spearman correlation. RESULTS ICC between measures ranged from fair (HPQ 0.59) to excellent (WPS-RA 0.78). Spearman correlations between measures were moderate (Qquality vs WAI, r = 0.51) to strong (WPS-RA vs WPAI, r = 0.88). Correlations between measures and general well-being were low to moderate, ranging from -0.44 ≤ r ≤ 0.66. CONCLUSION Test-retest results of 4 out of 5 global measures were good, and the correlations between these were moderate. The latter probably reflect differences in the concepts, recall periods, and references used in the measures, which implies that some measures are probably not interchangeable.

Abstract
Stable isotopes were used to develop authentication criteria of eggs laid under cage, barn, free range, and organic farming regimens from The Netherlands and New Zealand. A training set of commercial poultry feeds and egg albumen from 49 poultry farms across The Netherlands was used to determine the isotopic variability of organic and conventional feeds and to assess trophic effects of these corresponding feeds and barn, free range, and organic farming regimens on corresponding egg albumen. A further 52 brands of New Zealand eggs were sampled from supermarket shelves in 2008 (18), 2010 (30), and 2014 (4) to characterize and monitor changes in caged, barn, free range, and organic egg farming regimens. Stable carbon (δ(13)C) and nitrogen (δ(15)N) isotopes of 49 commercial poultry feeds and their corresponding egg albumens reveals that Dutch poultry are fed exclusively on a plant-based feed and that it is possible to discriminate between conventional and organic egg farming regimens in The Netherlands. Similarly, it is possible to discriminate between New Zealand organic and conventional egg farming regimens, although in the initial screening in 2008, results showed that some organic eggs had isotope values similar to those of conventional eggs, suggesting hens were not exclusively receiving an organic diet. Dutch and New Zealand egg regimens were shown to have a low isotopic correlation between both countries, because of different poultry feed compositions. In New Zealand, both conventional and organic egg whites have higher δ(15)N values than corresponding Dutch egg whites, due to the use of fishmeal or meat and bone meal (MBM), which is banned in European countries. This study suggests that stable isotopes (specifically nitrogen) show particular promise as a screening and authentication tool for organically farmed eggs. Criteria to assess truthfulness in labeling of organic eggs were developed, and we propose that Dutch organic egg whites should have a minimum δ(15)N value of 4.8‰ to account for an organic plant derived diet. Monitoring of New Zealand egg isotopes over the past 7 years suggests that organic eggs should have a minimum δ(15)N value of 6.0‰, and eggs falling below this value should be investigated further by certification authorities.

Abstract
Carbon isotopes (δ(13)C honey and δ(13)C protein) and apparent C-4 sugar contents of 1023 New Zealand honeys from 15 different floral types were analyzed to investigate which New Zealand honey is prone to failing the AOAC 998.12 C-4 sugar test and evaluate the occurrence of false-positive results. Of the 333 honey samples that exceeded the 7% C-4 sugar threshold, 324 samples of these were New Zealand manuka honey (Leptospermum scoparium, 97.2% of all fails found in the study). Three monofloral honeys (ling, kamahi, and tawari) had nine samples (2.8% of all fails found in the study) with apparent C-4 sugars exceeding 7%. All other floral types analyzed did not display C-4 sugar fails. False-positive results were found to occur for higher activity New Zealand manuka honey with a methylglyoxal content >250 mg/kg or a nonperoxide activity >10+, and for some ling, kamahi and tawari honeys. Recommendations for future interpretation of the AOAC 998.12 C-4 sugar method are proposed.

Abstract
BACKGROUND Research on the possible association between shiftwork and breast cancer is complicated because there are many different shiftwork factors, which might be involved including: light at night, phase shift, sleep disruption and changes in lifestyle factors while on shiftwork (diet, physical activity, alcohol intake and low sun exposure). METHODS We conducted a population-based case-control study in Western Australia from 2009 to 2011 with 1205 incident breast cancer cases and 1789 frequency age-matched controls. A self-administered questionnaire was used to collect demographic, reproductive, and lifestyle factors and lifetime occupational history and a telephone interview was used to obtain further details about the shiftwork factors listed above. RESULTS A small increase in risk was suggested for those ever doing the graveyard shift (work between midnight and 0500 hours) and breast cancer (odds ratio (OR)=1.16, 95% confidence interval (CI)=0.97-1.39). For phase shift, we found a 22% increase in breast cancer risk (OR=1.22, 95% CI=1.01-1.47) with a statistically significant dose-response relationship (P=0.04). For the other shiftwork factors, risks were marginally elevated and not statistically significant. CONCLUSION We found some evidence that some of the factors involved in shiftwork may be associated with breast cancer but the ORs were low and there were inconsistencies in duration and dose-response relationships.

Abstract
AIMS To evaluate the outcome of Scottish children with extra hepatic biliary atresia (EHBA) since rationalisation of Kasai services to three English centres in 2002 (The 'Group A' centres). METHODS All Scottish children with EHBA diagnosed between 2002 and 2009 were identified via the Scottish Society of Paediatric Gastroenterology, Hepatology and Nutrition (SSPGHAN) clinicians. A case-note review was conducted with demographics, presentation and outcome data recorded. These data were compared with historical Scottish data and data published previously by the supraregional liver units. RESULTS 25 patients were identified, of whom 22 were referred for Kasai in the group A centres, and of whom 19 had a Kasai. 2 year transplant-free survival (TFS) was significantly lower in the SSPGHAN 2002-2009 group than the group A centres in (1) (6/18 (33%) vs 36/57 (63%), p=0.023). CONCLUSIONS These postrationalisation data are disappointing. The emphasis for care will now focus on improved communication between, primary care, general paediatricians and surgical centres through regional and national managed clinical networks, aiming to improve future outcomes for Scottish children with BA.

Rising incidence of pediatric inflammatory bowel disease in Scotland. Inflamm Bowel Dis 2012; 18:999-1005. [PMID: 21688352 DOI: 10.1002/ibd.21797] [Citation(s) in RCA: 136] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2011] [Accepted: 05/16/2011] [Indexed: 02/06/2023]
Abstract
BACKGROUND An accurate indication of the changing incidence of pediatric inflammatory bowel disease (PIBD) within a population is useful in understanding concurrent etiological factors. We aimed to compare the current incidence and other demographic attributes of PIBD in the Scottish population to previous data. METHODS A national cohort of prospectively and retrospectively acquired incident cases of PIBD diagnosed less than 16 years old in pediatric services in Scotland was captured for the period 2003-2008; historical Scottish data were used for comparison (1990-1995). Age/sex-adjusted incidences were calculated and statistical comparisons made using Poisson regression. RESULTS During the 2003-2008 study period 436 patients were diagnosed with PIBD in Scotland, giving an adjusted incidence of 7.82/100,000/year. The incidence of Crohn's disease (CD) was 4.75/100,000/year, ulcerative colitis (UC) 2.06/100,000/year, and inflammatory bowel disease-unclassified (IBDU) 1.01/100,000/year. Compared with data from 1990-1995 when 260 IBD patients were diagnosed, significant rises in the incidence of IBD (from 4.45/100,000/year, P < 0.0001), CD (from 2.86/100,000/year, P < 0.0001), and UC (from 1.59/100,000/year, P = 0.023) were seen. There was also a significant reduction in the median age at IBD diagnosis from 12.7 years to 11.9 years between the periods (P = 0.003), with a continued male preponderance. CONCLUSIONS The number of Scottish children diagnosed with IBD continues to rise, with a statistically significant 76% increase since the mid-1990 s. Furthermore, PIBD is now being diagnosed at a younger age. The reason for this continued rise is not yet clear; however, new hypotheses regarding disease pathogenesis and other population trends may provide further insights in future years.

Abstract
BACKGROUND Adalimumab is efficacious therapy for adults with Crohn's disease (CD). AIM To summarise the United Kingdom and Republic of Ireland paediatric adalimumab experience. METHODS British Society of Paediatric Gastroenterology, Hepatology and Nutrition (BSPGHAN) members with Inflammatory Bowel Disease (IBD) patients <18 years old commencing adalimumab with at least 4 weeks follow-up. Patient demographics and details of treatment were then collected. Response and remission was assessed using the Paediatric Crohn's Disease Activity Index (PCDAI)/Physicians Global Assessment (PGA). RESULTS Seventy-two patients [70 CD, 1 ulcerative colitis (UC), 1 IBD unclassified (IBDU)] from 19 paediatric-centres received adalimumab at a median age of 14.8 (IQR 3.1, range 6.1-17.8) years; 66/70 CD (94%) had previously received infliximab. A dose of 80 mg then 40 mg was used for induction in 41(59%) and 40 mg fortnightly for maintenance in 61 (90%). Remission rates were 24%, 58% and 41% at 1, 6 and 12 months, respectively. Overall 43 (61%) went into remission at some point, with 24 (35%) requiring escalation of therapy. Remission rates were higher in those on concomitant immunosuppression cf. those not on immunosuppression [34/46 (74%) vs. 9/24 (37%), respectively, (χ(2) 8.8, P=0.003)]. There were 15 adverse events (21%) including four (6%) serious adverse events with two sepsis related deaths in patients who were also on immunosuppression and home parenteral nutrition (3% mortality rate). CONCLUSIONS Adalimumab is useful in treatment of refractory paediatric patients with a remission rate of 61%. This treatment benefit should be balanced against side effects, including in this study a 3% mortality rate.
