RESUMEN
Fatigue is prevalent amongst people with long COVID, but is poorly understood. The sensory attenuation framework proposes that impairments in sensory processing lead to heightened perception of effort, driving fatigue. This study aims to investigate the role of somatosensory processing impairments in long COVID fatigue and quantify how sensory processing relates to other prominent symptoms of long COVID including autonomic dysfunction, mood and illness beliefs in driving the experience of fatigue. We will recruit 44 individuals with long COVID fatigue and 44 individuals with neither long COVID nor fatigue (controls). Our primary objective is to compare baseline somatosensory processing between individuals with long COVID fatigue and controls. Additionally, we will explore the associations between somatosensory processing, fatigability and the level of fatigue induced by cognitive and physical exertion. Due to the complex nature of fatigue, we will also investigate how long COVID, state fatigue, perceived effort, mood, illness beliefs, autonomic symptoms and autonomic nervous system function interact to predict trait fatigue. This comprehensive investigation aims to elucidate how sensory processing and other prominent symptoms interact to impact the experience of fatigue.
RESUMEN
OBJECTIVE: To understand whether self-sampling can reduce carbon emissions (CO2 e) from the NHS cervical screening programme (NHSCSP) by comparing the carbon footprint of three sampling strategies: routine cervical sampling, vaginal self-sampling and first-void (FV) urine collection. DESIGN: Descriptive study. SETTING: National Health Service (NHS), United Kingdom (UK). POPULATION OR SAMPLE: Patients aged 25-64 years eligible for cervical screening in the UK. METHODS: A carbon footprint analysis was undertaken for three cervical screening sampling approaches, from point of invitation to screening through to preparation for transport to the laboratory for HPV testing. A combination of primary and secondary data were used, with a bottom-up approach applied to collection of primary data. MAIN OUTCOME MEASURES: We report CO2 e per sampling approach, which is the unit used to express carbon footprint and harmonise the contributions of greenhouse gases with different global warming potentials. RESULTS: The total carbon footprint of routine cervical sampling is 3670 g CO2 e. By comparison, vaginal self-sampling had a total carbon footprint of 423 g CO2 e, and FV urine sampling 570 g CO2 e. The largest share of emissions for routine sampling was attributable to the carbon footprint associated with an appointment in a primary care setting, which totalled 2768 g CO2 e. CONCLUSIONS: Routine cervical sampling is up to 8.7-fold more carbon-intensive than self-sampling approaches with equivalent effectiveness. We found negligible differences in the carbon footprint of alternative self-sampling methods, supporting the need for an informed choice of screening options for participants, which includes sharing information on their environmental impacts.

OBJECTIVE: To evaluate the sensitivity of human papillomavirus (HPV) tested urine to detect high-grade cervical precancer (cervical intraepithelial neoplasia grade 2+ [CIN2+]) using two urine collection devices. DESIGN: Randomised controlled trial. SETTING: St Mary's Hospital, Manchester, UK. POPULATION: Colposcopy attendees with abnormal cervical screening; a total of 480 participants were randomised. Matched urine and cervical samples were available for 235 and 230 participants using a first-void urine (FVU)-collection device and standard pot, respectively. METHODS: Urine was self-collected and mixed with preservative - randomised 1:1 to FVU-collection device (Novosanis Colli-pee® 10 mL with urine conservation medium [UCM]) or standard pot. Matched clinician-collected cervical samples were taken before colposcopy. HPV testing used Roche cobas® 8800. A questionnaire evaluated urine self-sampling acceptability. MAIN OUTCOME MEASURES: The primary outcome measured sensitivity of HPV-tested urine (FVU-collection device and standard pot) for CIN2+ detection. Secondary outcomes compared HPV-tested cervical and urine samples for CIN2+ and evaluated the acceptability of urine self-sampling. RESULTS: Urine HPV test sensitivity for CIN2+ was higher with the FVU-collection device (90.3%, 95% CI 83.7%-94.9%, 112/124) than the standard pot (73.4%, 95% CI 64.7%-80.9%, 91/124, p = 0.0005). The relative sensitivity of FVU-device-collected urine was 0.92 (95% CI 0.87-0.97, pMcN = 0.004) compared with cervical, considering that all women were referred after a positive cervical HPV test. Urine-based sampling was acceptable to colposcopy attendees. CONCLUSIONS: Testing of FVU-device-collected urine for HPV was superior to standard-pot-collected urine in colposcopy attendees and has promising sensitivity for CIN2+ detection. General population HPV testing of FVU-device-collected urine will establish its clinical performance and acceptability as an alternative to routine cervical screening.
RESUMEN
BACKGROUND: Cervical cancer remains an important global public health concern. Understanding the factors contributing to a decline in screening uptake in high-income countries is fundamental to improving screening rates. We aimed to identify general practice and patient characteristics related to cervical screening coverage in England between 2013 and 2022. METHODS: We analyzed a panel of 59 271 General Practice (GP)-years from 7881 GP practices. We applied correlated random effects regression to examine the association between cervical screening uptake and a rich set of GP practice workforce, size, quality and patient characteristics. RESULTS: Our results show a decline in overall screening rates from 2013/14 to 2021/22 from 77% to 72%. We find GP workforce and list size characteristics are strongly related to screening rates. An increase in 1 FTE Nurse per 1000 patients is related to a 1.94 percentage point increase in cervical screening rates. GP practices located in more deprived areas have lower screening rates. CONCLUSIONS: GP workforce and patient characteristics need to be considered by decision-makers to increase screening rates. The implementation of self-sampling screening methods could help address some of the current barriers to screening, including lack of healthcare staff and facilities.

Inertial measurement units (IMUs) offer a portable and quantitative solution for clinical movement analysis. However, their application in non-specific low back pain (NSLBP) remains underexplored. This study compared the spine and pelvis kinematics obtained from IMUs between individuals with and without NSLBP and across clinical subgroups of NSLBP. A total of 81 participants with NSLBP with flexion (FP; n = 38) and extension (EP; n = 43) motor control impairment and 26 controls (No-NSLBP) completed 10 repetitions of spine movements (flexion, extension, lateral flexion). IMUs were placed on the sacrum, fourth and second lumbar vertebrae, and seventh cervical vertebra to measure inclination at the pelvis, lower (LLx) and upper (ULx) lumbar spine, and lower cervical spine (LCx), respectively. At each location, the range of movement (ROM) was quantified as the range of IMU orientation in the primary plane of movement. The ROM was compared between NSLBP and No-NSLBP using unpaired t-tests and across FP-NSLBP, EP-NSLBP, and No-NSLBP subgroups using one-way ANOVA. Individuals with NSLBP exhibited a smaller ROM at the ULx (p = 0.005), LLx (p = 0.003) and LCx (p = 0.01) during forward flexion, smaller ROM at the LLx during extension (p = 0.03), and a smaller ROM at the pelvis during lateral flexion (p = 0.003). Those in the EP-NSLBP group had smaller ROM than those in the No-NSLBP group at LLx during forward flexion (Bonferroni-corrected p = 0.005), extension (p = 0.013), and lateral flexion (p = 0.038), and a smaller ROM at the pelvis during lateral flexion (p = 0.005). Those in the FP-NSLBP subgroup had smaller ROM than those in the No-NSLBP group at the ULx during forward flexion (p = 0.024). IMUs detected variations in kinematics at the trunk, lumbar spine, and pelvis among individuals with and without NSLBP and across clinical NSLBP subgroups during flexion, extension, and lateral flexion. These findings consistently point to reduced ROM in NSLBP. The identified subgroup differences highlight the potential of IMU for assessing spinal and pelvic kinematics in these clinically verified subgroups of NSLBP.

Background: Strongylus vulgaris is one of the most pathogenic nematodes affecting equids. Larval migration through the cranial mesenteric artery (CMA) with attendant arteritis and thromboembolism can result in fatal non-strangulating intestinal infarction. Once considered a historical disease, recent studies have described the reemergence of this pathogen in several European countries; however, little is known of the current prevalence of S. vulgaris in the Canadian horse population. Objective: To determine the prevalence of active S. vulgaris cranial mesenteric arteritis in horses submitted for postmortem examination to the Diagnostic Services Unit (DSU) at the University of Calgary Faculty of Veterinary Medicine. Animals and procedure: We conducted a retrospective review of all equine postmortem cases submitted to the DSU between July 1, 2010 and June 30, 2022. Over 12 y, 510 horses > 2 mo of age from Alberta were submitted to the DSU for necropsy. Active cases were defined as those with endarteritis and thrombosis in the CMA or its branches. Those cases with only intimal scarring of the CMA were classified as historical. Results: The prevalence of all CMA lesions (both historical and active) over the study period was 17.3% (88/510). Active S. vulgaris cranial mesenteric arteritis was documented in 6.1% (31/510) of equine postmortems and the sequelae of verminous arteritis were the cause of euthanasia or death in 1.5% (8/510) of the cases submitted. Conclusion and clinical relevance: Even after historically intense efforts to eradicate this parasite, the continued effects of S. vulgaris are demonstrated by the results of this study. Strongylus vulgaris should not be regarded as a parasite of the past and verminous arteritis remains an important differential diagnosis for horses in western Canada presenting with mild colic or dull demeanor and anorexia of duration > 24 h. Furthermore, S. vulgaris should be taken into careful consideration when implementing antiparasitic control strategies. Practitioners should remain current on prevention, diagnosis, and treatment of this potentially reemerging and fatal equine disease.
Étude rétrospective de la prévalence lors d'autopsies équines de l'artérite mésentérique crâniale causée par Strongylus vulgaris en Alberta (2010 à 2022). Contexte: Strongylus vulgaris est l'un des nématodes les plus pathogènes affectant les équidés. La migration des larves à travers l'artère mésentérique crâniale (CMA), accompagnée d'artérite et de thromboembolie, peut entraîner un infarctus intestinal non étranglant mortel. Autrefois considérée comme une maladie historique, des études récentes ont décrit la réémergence de cet agent pathogène dans plusieurs pays européens; cependant, on sait peu de choses sur la prévalence actuelle de S. vulgaris dans la population équine canadienne. Objectif: Déterminer la prévalence de l'artérite mésentérique crâniale active à S. vulgaris chez les chevaux soumis pour examen post mortem au Diagnostic Service Unit (DSU), College of Veterinary Medicine, University of Calgary. Animaux et procédure: Nous avons effectué un examen rétrospectif de tous les cas post-mortem d'équidés soumis au DSU entre le 1er juillet 2010 et le 30 juin 2022. Sur 12 ans, 510 chevaux âgés de plus de 2 mois de l'Alberta ont été soumis au DSU pour autopsie. Les cas actifs ont été définis comme ceux présentant une endartérite et une thrombose dans la CMA ou ses branches. Les cas présentant uniquement des cicatrices à l'intima de la CMA ont été classés comme anciens. Résultats: La prévalence de toutes les lésions de CMA (anciennes et actives) au cours de la période d'étude était de 17,3 % (88/510). Une artérite mésentérique crâniale active à S. vulgaris a été documentée dans 6,1 % (31/510) des autopsies équines et les séquelles de l'artérite vermineuse ont été la cause de l'euthanasie ou du décès dans 1,5 % (8/510) des cas soumis. Conclusion et pertinence clinique: Malgré des efforts historiquement intenses pour éradiquer ce parasite, les effets continus de S. vulgaris sont démontrés par les résultats de cette étude. Strongylus vulgaris ne doit pas être considéré comme un parasite du passé et l'artérite vermineuse demeure un diagnostic différentiel important pour les chevaux de l'ouest du Canada présentant des coliques légères ou un comportement abattu et une anorexie de durée > 24 h. De plus, S. vulgaris doit être attentivement pris en compte lors de la mise en Åuvre de stratégies de contrôle antiparasitaire. Les praticiens doivent rester informés de la prévention, du diagnostic et du traitement de cette maladie équine potentiellement ré-émergente et mortelle.(Traduit par Dr Serge Messier).

OBJECTIVES: To understand the use, functionality and interoperability of laboratory information management systems (LIMS) in UK transfusion laboratories. BACKGROUND: LIMS are widely used to support safe transfusion practice. LIMS have the potential to reduce the risk of laboratory error using algorithms, flags and alerts that support compliance with best practice guidelines and regulatory standards. Reporting to Serious Hazards of Transfusion (SHOT), the United Kingdom (UK) haemovigilance scheme, has identified cases where the LIMS could have prevented errors but did not. Shared care of patients across different organisations and the development of pathology networks has raised challenges relating to interoperability of IT systems both within, and between, organisations. METHODS AND MATERIALS: A survey was distributed to all SHOT-reporting organisations to understand the current state of LIMS in the UK, prevalence of expertise in transfusion IT, and barriers to progress. Survey questions covered LIMS interoperability with other IT systems used in the healthcare setting. RESULTS: A variety of LIMS and version numbers are in use in transfusion laboratories, LIMS are not always updated due to resource constraints. Respondents identified interoperability and improved functionality as the main requirements for transfusion safety. CONCLUSION: A nationally agreed set of minimum standards for transfusion LIMS is required for safe practice. Adequate resources, training and expertise should be provided to support the effective use and timely updates of LIMS. A single LIMS solution should be in place for transfusion laboratories working within a network and interoperability with other systems should be explored to further improve practice.

Adenoviral hemorrhagic disease (AHD), caused by deer atadenovirus A (OdAdV-1), affects captive and free-ranging cervids across North America. Here we present a case of AHD in a 6-month-old female elk calf from a farm in Alberta. Histopathology revealed multisystemic vasculitis with endothelial intranuclear inclusion bodies, pulmonary hemorrhage, and small intestinal hemorrhage characteristic of the acute systemic form of AHD. Immunohistochemistry was positive for OdAdV-1, confirming the diagnosis. Whole-genome sequencing of the virus was conducted for phylogenetic comparison. This is the 1st reported case of AHD in a farmed elk in Canada and the 1st reported case in an elk in Alberta. Key clinical message: Adenoviral hemorrhagic disease (AHD) is an emerging disease that should be investigated as a top differential when diagnosticians and veterinarians encounter young cervids found dead with pulmonary edema or hemorrhage and/or hemorrhagic enteropathy.
Maladie hémorragique adénovirale chez un wapiti d'élevage (Cervus canadensis) en Alberta, Canada. La maladie hémorragique adénovirale (AHD), causée par l'atadénovirus A du cerf (OdAdV-1), affecte les cervidés en captivité et en liberté partout en Amérique du Nord. Nous présentons ici un cas d'AHD chez un wapiti femelle de 6 mois d'une ferme en Alberta. L'histopathologie a révélé une vascularite multi-systémique avec des corps d'inclusion intranucléaires endothéliaux, une hémorragie pulmonaire et une hémorragie de l'intestin grêle caractéristiques de la forme systémique aiguë de l'AHD. L'immunohistochimie était positive pour OdAdV-1, confirmant le diagnostic. Le séquençage du génome entier du virus a été réalisé à des fins de comparaison phylogénétique. Il s'agit du premier cas signalé d'AHD chez un wapiti d'élevage au Canada et du premier cas signalé chez un wapiti en Alberta.Message clinique clé :La maladie hémorragique adénovirale (AHD) est une maladie émergente qui devrait être investiguée comme un diagnostic différentiel important lorsque les diagnosticiens et les vétérinaires rencontrent de jeunes cervidés trouvés morts avec un Ådème pulmonaire ou une hémorragie et/ou une entéropathie hémorragique.(Traduit par Dr Serge Messier).

Approximately 30% of adult-onset systemic lupus erythematosus (SLE) patients develop lupus nephritis (LN). The gold standard for LN detection involves renal biopsies, invasive procedures not suitable for routine disease monitoring. A urinary biomarker panel comprised of lipocalin-like prostaglandin D synthase (LPGDS), transferrin, alpha-1-acid glycoprotein (AGP-1), ceruloplasmin, monocyte chemoattractant protein 1 (MCP-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) has shown promise to predict LN and response to rituximab at baseline. Whether these proteins predict LN during longitudinal sampling, however, remained unknown. Here, we quantified aforementioned urinary proteins at baseline (N = 25), six and twelve months (N = 17 each) after rituximab treatment. Urine MCP-1 (at six and twelve months) and AGP-1 (at twelve months) levels varied between patients with active vs mildly active/inactive LN. Findings support the use of urinary proteins to detect active LN in ongoing disease monitoring in adult-onset SLE patients, but need to be validated in larger cohorts.

OBJECTIVE: To review the effect of the COVID-19 pandemic on the diagnosis of cervical cancer and model the impact on workload over the next 3 years. DESIGN: A retrospective, control, cohort study. SETTING: Six cancer centres in the North of England representing a combined population of 11.5 million. METHODS: Data were collected retrospectively for all diagnoses of cervical cancer during May-October 2019 (Pre-COVID cohort) and May-October 2020 (COVID cohort). Data were used to generate tools to forecast case numbers for the next 3 years. MAIN OUTCOME MEASURES: Histology, stage, presentation, onset of symptoms, investigation and type of treatment. Patients with recurrent disease were excluded. RESULTS: 406 patients were registered across the study periods; 233 in 2019 and 173 in 2020, representing a 25.7% (n = 60) reduction in absolute numbers of diagnoses. This was accounted for by a reduction in the number of low stage cases (104 in 2019 to 77 in 2020). Adding these data to the additional cases associated with a temporary cessation in screening during the pandemic allowed development of forecasts, suggesting that over the next 3 years there would be 586, 228 and 105 extra cases of local, regional and distant disease, respectively, throughout England. Projection tools suggest that increasing surgical capacity by two or three cases per month per centre would eradicate this excess by 12 months and 7 months, respectively. CONCLUSIONS: There is likely to be a significant increase in cervical cancer cases presenting over the next 3 years. Increased surgical capacity could mitigate this with little increase in morbidity or mortality. TWEETABLE ABSTRACT: Covid will result in 919 extra cases of cervical cancer in England alone. Effects can be mitigated by increasing surgical capacity.

BACKGROUND: Effective transfer of information relating to patient care is vital in healthcare. In the UK formal handover is an established and well reported process in the clinical setting but less so in transfusion laboratories. Blood transfusions occur within many hospital specialities and across clinical and laboratory staff shifts, making robust handover critical for safe practice. Failure to adequately transfer information relating to pending or ongoing provision of blood components during shift handover in the laboratory can have an adverse impact on patient care. AIMS: To identify transfusion errors where laboratory handover was considered a contributory factor. MATERIALS AND METHODS: Serious adverse events and reactions reported to the UK haemovigilance scheme, Serious Hazards of Transfusion (SHOT), involving handover in the transfusion laboratory were reviewed for a 6-year period. RESULTS: Laboratory incidents involving handover were mainly associated with incorrect blood component transfused-specific requirements not met (IBCT-SRNM) and delays in provision of blood components transfusion, with 16.6% of these cases involving major haemorrhage situations. Handover was found to be insufficient in most cases, no handover was completed in 29.5% of cases, inadequate written handover accounted for 14.8% cases, and inadequate verbal for 5.7% of cases. DISCUSSION: Poor handover can lead to laboratory errors, particularly delays in provision of blood components. Embedding effective handover processes in the laboratory and including handover time within the shift working pattern, may help reduce errors and ensure continuity of care. CONCLUSION: Handover should be considered a task that is built into laboratory routine practices, ensuring effective transfer of information and appropriate follow up actions are taken. SHOT have created a handover template which can be adopted in laboratories to formalise this process.

A well-differentiated neuroendocrine carcinoma of the stomach (gastric carcinoid) with transcoelomic and lymph node metastasis was confirmed on post-mortem examination of a 3-year-old, spayed female, domestic ferret (Mustela putorius furo). The animal was initially presented with a history of persistent vomiting which progressed to weight loss, a palpable abdominal mass, and melena. The ferret received palliative treatment and was euthanized 9 mo after initial presentation. The clinical, ultrasonographical, cytological, gross pathological, histopathological, and immunohistochemical findings are described. Gastric neuroendocrine carcinomas are rarely reported in animals; this is the first description in a ferret. Key clinical message: Veterinary practitioners and diagnosticians should include neuroendocrine carcinoma as a differential diagnosis when encountering gastric neoplasms in ferrets and be aware of the potential for aggressive behavior and widely spread metastasis.

L'animal a été initialement présenté avec des antécédents de vomissements persistants qui ont évolué vers une perte de poids, une masse abdominale palpable et un méléna. Le furet a reçu un traitement palliatif et a été euthanasié 9 mois après la présentation initiale. Les résultats cliniques, échographiques, cytologiques, de pathologie macroscopique, histopathologiques et immunohistochimiques sont décrits. Les carcinomes neuroendocriniens gastriques sont rarement rapportés chez les animaux; c'est la première description chez un furet.Message clinique clé:Les praticiens vétérinaires et les diagnosticiens doivent inclure le carcinome neuroendocrinien comme diagnostic différentiel lorsqu'ils rencontrent des néoplasmes gastriques chez les furets et être conscients du potentiel de comportement agressif et de métastases largement disséminées.(Traduit par Dr Serge Messier).

Prader-Willi syndrome (PWS) is a neurodevelopmental disorder caused by deletion or inactivation of paternally expressed imprinted genes on human chromosome 15q11-q13. In addition to endocrine and developmental issues, PWS presents with behavioural problems including stereotyped behaviour, impulsiveness and cognitive deficits. The PWS genetic interval contains several brain-expressed small nucleolar (sno) RNA species that are subject to genomic imprinting, including snord115 that negatively regulates post-transcriptional modification of the serotonin 2C receptor (5-HT2CR) pre-mRNA potentially leading to a reduction in 5-HT2CR function. Using the imprinting centre deletion mouse model for PWS (PWSICdel) we have previously shown impairments in a number of behaviours, some of which are abnormally sensitive to 5-HT2CR-selective drugs. In the stop-signal reaction time task test of impulsivity, PWSICdel mice showed increased impulsivity relative to wild-type (WT) littermates. Challenge with the selective 5-HT2CR agonist WAY163909 reduced impulsivity in PWSICdel mice but had no effect on WT behaviour. This behavioural dissociation in was also reflected in differential patterns of immunoreactivity of the immediate early gene c-Fos, with a blunted response to the drug in the orbitofrontal cortex of PWSICdel mice, but no difference in c-Fos activation in the nucleus accumbens. These findings suggest specific facets of response inhibition are impaired in PWSICdel mice and that abnormal 5-HT2CR function may mediate this dissociation. These data have implications for our understanding of the aetiology of PWS-related behavioural traits and translational relevance for individuals with PWS who may seek to control appetite with the new obesity treatment 5-HT2CR agonist lorcaserin.

OBJECTIVES: â¼30% of patients with SLE develop LN. Presence and/or severity of LN are currently assessed by renal biopsy, but biomarkers in serum or urine samples may provide an avenue for non-invasive routine testing. We aimed to validate a urinary protein panel for its ability to predict active renal involvement in SLE. METHODS: A total of 197 SLE patients and 48 healthy controls were recruited, and urine samples collected. Seventy-five of the SLE patients had active LN and 104 had no or inactive renal disease. Concentrations of lipocalin-like prostaglandin D synthase (LPGDS), transferrin, alpha-1-acid glycoprotein (AGP-1), ceruloplasmin, monocyte chemoattractant protein 1 (MCP-1) and soluble vascular cell adhesion molecule-1 (sVCAM-1) were quantified by MILLIPLEX® Assays using the MAGPIX Luminex platform. Binary logistic regression was conducted to examine whether proteins levels associate with active renal involvement and/or response to rituximab treatment. RESULTS: Urine levels of transferrin (P <0.005), AGP-1 (P <0.0001), MCP-1 (P <0.001) and sVCAM-1 (P <0.005) were significantly higher in SLE patients when compared with healthy controls. Furthermore, levels of transferrin, AGP-1, ceruloplasmin, MCP-1 and sVCAM-1 (all P <0.0001) were higher in SLE patients with active LN when compared with patients without active LN. A combination of five urine proteins, namely LPGDS, transferrin, ceruloplasmin, MCP-1 and sVCAM-1 was a good predictor of active LN (AUC 0.898). A combined model of LPGDS, transferrin, AGP-1, ceruloplasmin, MCP-1 and sVCAM-1 predicted response to rituximab treatment at 12 months (AUC 0.818). CONCLUSIONS: Findings support the use of a urinary protein panel to identify active LN and potentially predict response to treatment with rituximab in adult SLE patients. Prospective studies are required to confirm findings.

INTRODUCTION: Inguino-femoral lymph node dissection plays a crucial role in the management of vulvar cancer. The procedure is associated with high complication rates, including infection, lymphocysts/lymphoedema and wound dehiscence. Several skin incision techniques exist and practice among gynecology oncologists is variable. Little evidence exists to guide surgeons regarding the optimal surgical approach. This study aimed to determine the difference in 30-day complication rates, number of lymph nodes and length of stay between patients undergoing the modified oblique and classical 'lazy S' skin incision. METHODS: A retrospective review between January 2014 and September 2018 was performed in the University Hospital of Wales, Cardiff. All cases of inguino-femoral lymph node dissection performed for vulvar cancer were included in the study without exclusion. Data collected included age, body mass index (BMI), incision type, suture material, length of hospital stay, complication rates, cancer stage, lymph node count, lymph node positivity rate and recurrence rates. Data were analyzed using SPSS software and clinical significance was set as p<0.05. RESULTS: Thirty-five cases of classical 'lazy S' and 14 cases of modified oblique were included in the analysis. The mean patient age was 65 years (range 41-86) in the classical 'lazy S' group and 58 years (range 19-81) in the modified oblique group. The mean BMI was 28 kg/m2 (range 18-45) in the classical 'lazy S' group and 29 kg/m2 (range 20-36) in the modified oblique group. In the classical 'lazy S' group, the stage classification was as follows: stage IB (18), II (2), IIIA (3), IIIB (4), IIIC (8). In the modified oblique group, the stage classification was: stage IB (8), II (4), IIIA (2). Grade 3-4 complications were statistically significantly more common after the classical 'lazy S' versus the modified oblique operation (20/35, 57.1% vs 2/14, 14.3%, p<0.02). Mean number of nodes harvested was statistically significantly higher in the classical 'lazy S' group compared with the modified oblique group (11.1 nodes, range 6-17 vs 7 nodes, range 4-11, p<0.001). Node positivity rate was higher in the classical 'lazy S' group compared with the modified oblique group (28.6% vs 10%, p=0.08). Mean hospital stay was statistically significantly longer in patients undergoing classical 'lazy S' versus modified oblique (10.7 vs 4.5 days, p=0.02). One case of groin node recurrence occurred and this patient was in the classical 'lazy S' arm. CONCLUSION: The rate of overall and serious complications was lower after modified oblique skin incision compared with classical 'lazy S'. However, the absolute lymph node count and lymph node positivity rate were higher in the 'lazy S' group.

Septicemic pasteurellosis is an acute and fatal bacterial disease of cattle and wild ungulates caused by certain serotypes of Pasteurella multocida. Here we report a single case of septicemic pasteurellosis in a 6-month-old, Red Angus heifer from a cow-calf operation in Alberta, Canada. Postmortem examination revealed necrotizing and hemorrhagic myositis, fibrinous pericarditis and multisystemic bacterial emboli. Pasteurella multocida was isolated from muscle in pure culture, and the capsular antigen group was identified as serogroup B using polymerase chain reaction. To the best of our knowledge, this is the first reported case of septicemic pasteurellosis in beef cattle in Canada. Key clinical message: Veterinary practitioners and diagnosticians should include septicemic pasteurellosis on their list of differential diagnoses when they encounter similar presentations of peracute death and severe necrotizing myositis in cattle in Canada.
Pasteurellose septicémique causant la mort suraiguë et une myosite nécrosante d'une génisse d'embouche ( Bos taurus ) en Alberta, Canada. La pasteurellose septicémique est une maladie bactérienne aiguë et fatale des bovins et des ongulés sauvages causée par certains sérotypes de Pasteurella multocida. Nous rapportons ici un cas unique de pasteurellose septicémique chez une génisse Red Angus âgée de 6 mois provenant d'un élevage vache-veau en Alberta, Canada. L'examen post-mortem a révélé une myosite nécrosante et hémorragique, une péricardite fibrineuse et des embolies bactériennes multi-systémiques. Pasteurella multocida fut isolé du muscle en culture pure, et l'antigène de groupe capsulaire fut identifié comme étant le sérogroupe B à l'aide de la réaction d'amplification en chaîne utilisant la polymérase. À notre connaissance ceci représente le premier cas rapporté de pasteurelle septicémique chez des bovins d'embouche au Canada.Message clinique clé:Les vétérinaires praticiens et les diagnosticiens devraient inclure la pasteurellose septicémique sur leur liste de diagnostic différentiel lorsqu'ils rencontrent des présentations similaires de mortalité suraiguë et de myosite nécrosante sévère chez des bovins au Canada.(Traduit par Dr Serge Messier).

BACKGROUND: This multicenter international study evaluated electronic remote blood issue (ERBI) for blood unit collection in hospitals. STUDY DESIGN AND METHODS: Retrospective data were collected from the ERBI software databases and blood bank information systems. Prospective "time-and-motion" data collection methods simulated the delivery of red blood cell units to determine the staff time for each step. RESULTS: The main benefit of ERBI was found in two hospitals where the blood unit was issued and collected at refrigerators remote from the blood bank (closer to the clinical area) compared with the standard process of blood bank issue (BBI) and blood unit collection in the blood bank. There was a reduction in the time for blood to reach patients (2.02 min compared to 8.43 min at one site [p ≤ 0.0001], 1.57 min compared to 6.54 min at the other [p ≤ 0.0001]). However, there was no reduction in time where ERBI was conducted in the blood bank or where a blood unit issued by the standard BBI was collected at remote refrigerators. In the three hospitals where ERBI was conducted at remote refrigerators, there was an improved issue:transfusion ratio (range of 1.02-1.09 for ERBI compared to 1.48-1.58 for BBI) and a reduction in staff time and costs of between $5,000 and $10,000/year. CONCLUSION: This multicenter international study builds on findings from studies in single hospitals that ERBI at remote refrigerators improves the efficiency of transfusion by reducing the time taken for blood units to reach patients, staff time, and costs.

Literature can offer a wealth of information about epilepsy: from complex narratives to children's picture books, it can help broaden people's understanding, show what it is like to live with epilepsy and provide a medium to which people with epilepsy (PWE) can relate. The latter being particularly important in such cases where seizure experiences are highly subjective, such as those associated with 'focal seizures', a common seizure type, which are known for their variable and hard-to-describe symptoms, causing complications with diagnosis as many of the symptoms overlap with those of other psychological health conditions.Literature, however, has more to offer than acting as a source for demystifying epilepsy. On a disciplinary level, literature is surrounded by different frameworks for linguistic analysis which, importantly, are also applicable to real-life discourse. In particular, the well-established discipline, cognitive stylistics, provides ample theory for analysing the different facets of literature, from narratological and storyworld level, to the intricacies of characterisation revealing the structure behind the presentation of fictional characters' experiences, attitudes and personalities. Such methods have the potential to transform and decode complex, subjective experiences into manageable pieces of information. This, then, holds great potential for shedding light on the experiences of real-life seizure narratives to the extent that the identified seizure's linguistic 'profiles' can be used to aid real-life situations. Therefore, the present study calls to attention the potential evoked through the convergence between literature, linguistic analysis, fictional characters, PWE and seizure narratives. Extrapolating the qualities of these converging strands can enrich our understanding of the seizure experience, as well as bring to awareness the areas of risk that surround aspects of the diagnosis process.
