RETROSPECTIVE COHORT STUDY ON EVAR OPEN SURGICAL CONVERSION: FOCUS ON ENDOLEAKS WRONG PRE OPERATIVE CATEGORISATION.

INTRODUCTION: Late open conversion (LOC) following endovascular aneurysm repair (EVAR) is a rare complication with a high morbidity and mortality and is often proposed as the last line of treatment after failure of endovascular reintervention of any type. This study aimed to highlights the limitations of EVAR follow-up imaging in characterizing endoleaks, which may contribute to the failure of endovascular reinterventions and lead to LOC. METHODS: This retrospective cohort study recruited all EVAR implanted in Amiens University Hospital (France) between January 2008 and December 2022. Elective LOC was defined as surgical conversion > 1 month after EVAR. The primary endpoint was the rate of wrong categorisation of endoleaks by follow-up exams before LOC. Secondary endpoints were the morbidity and the mortality associated with LOC. RESULTS: Seven hundred and eight EVAR were performed in our institution, 30 required elective LOC. Twenty-five of them were treated for sac enlargement due to an endoleak (83,3%) (all types). Wrong categorisation of the endoleak was noted in 13 of the patients (52.2%). Twelve of these re-categorisations involved the preoperative diagnosis of a type II endoleaks (92.3%). The change in categorisation in 7 out of 12 cases (58%) was in favor of a type I endoleak, other re-categorisation included 1 Type III (8%), 4 Types IV (33%). One patient died during 30 days post-operative period and 7 patients (28%) presented a major complication, the median length of stay was 13 days (IQR 9-21). CONCLUSION: Routine follow-up examinations such as angioscanner and contrast Doppler ultrasound appear to be limited in their ability to categorise the type of persistent endoleak, which may increase the number of patients requiring LOC. New precision diagnostic imaging techniques, such as dynamic examinations, need to be developed to limit the need for LOC.

Fears about COVID-19 and perceived risk among people with rheumatoid arthritis or ankylosing spondylitis following the initial lockdown in Aotearoa New Zealand.

BACKGROUND: The COVID-19 pandemic has disrupted all aspects of life and may raise particular fears for people with rheumatic disease. There is a need for research on fears and perceived risk of SARS-CoV-2 so as to understand the impact on wellbeing and inform service provision. OBJECTIVES: The aim of this study was to examine the correlates of COVID-19 fears and perceived risk of SARS-CoV-2 among people with rheumatoid arthritis or ankylosing spondylitis. DESIGN: A cross-sectional survey design was applied in Aotearoa New Zealand in the period after initial nationwide lockdowns. METHOD: An online survey was completed from July to September 2020 by 126 individuals with rheumatoid arthritis (n = 96) or ankylosing spondylitis (n = 30) who had previously been recruited to the Patient Opinion Real-Time Anonymous Liaison (PORTAL) study in 2015 or 2018. The survey included demographics and health information as well as measures of COVID-19 fears and experiences, functional disability and fatigue-related disability. RESULTS: Fears about COVID-19 were higher among younger participants, those who had been tested for SARS-CoV-2, and those who experienced more flares over the initial lockdown. Perceived risk of SARS-CoV-2 infection was also higher among individual who had been tested for SARS-CoV-2 and those taking biologic medications. CONCLUSION: Fears about COVID-19 and perceived risk of infection are related to age, health and medications among individuals with rheumatoid arthritis or ankylosing spondylitis. These findings inform how health professionals can help address the concerns of particular groups of people with rheumatic disease by providing relevant information about the ongoing effects of the pandemic.

Mental health and quality of life for people with rheumatoid arthritis or ankylosing spondylitis in Aotearoa New Zealand following the COVID-19 national lockdown.

The aim of this study was to investigate the effects of lockdown on the mental health (anxiety and depression) and quality of life (QOL) of people with rheumatoid arthritis (RA) and ankylosing spondylitis (AS) in the context of the COVID-19 pandemic and public health measures instituted at a national level by the New Zealand Government. The present cohort was 104 individuals with RA (73.1%) and AS (26.9%) who had previously completed surveys for the Patient Opinion Real-Time Anonymous Liaison (PORTAL) project in 2018. Participants completed an online survey between July and September 2020 assessing their experiences over the first national COVID-19 lockdown in New Zealand (March-May, 2020). Fear of SARS-CoV-2 infection, baseline anxiety, and being younger in age were all predictors of participants' current anxiety levels. Current QOL scores were significantly lower than prior to lockdown and were predicted by baseline QOL and current depression. No variables predicted current depression other than baseline levels. The COVID-19 pandemic appears to have had an impact on QOL and anxiety levels, but not depression for people with RA and AS in New Zealand. These novel findings imply that appropriate screening of mental health issues should be included in planning within the ongoing COVID-19 pandemic and for future pandemics to optimise the wellbeing of people with RA and AS.

Understanding Fatigue-Related Disability in Rheumatoid Arthritis and Ankylosing Spondylitis: The Importance of Daily Correlates.

OBJECTIVE: Fatigue is common among people with inflammatory arthritis but is hard to manage. The aim of this study was to investigate how daily fluctuations in psychological variables correspond with changes in fatigue-related disability in the daily lives of people with inflammatory arthritis and to identify factors to target in psychological interventions and routine clinical practice. METHODS: A cohort of 143 patients with rheumatoid arthritis (n = 97) or ankylosing spondylitis (n = 46) participated in a 10-day online diary study. Each evening participants completed a diary questionnaire assessing their fatigue, pain, fatigue-related disability, and 4 components of psychological flexibility (valued activity, mindfulness, cognitive fusion, and fatigue avoidance). RESULTS: On days when participants were more engaged in valued activities or more mindful, they reported less disability due to fatigue, even when controlling for levels of fatigue and pain that day. The daily psychological flexibility variables explained a total of 15.6% of the variance in daily fatigue-related disability. CONCLUSION: Psychological flexibility variables are directly associated with fatigue-related disability in the daily lives of inflammatory arthritis patients. Further research is needed to investigate whether interventions that target psychological flexibility are effective at reducing fatigue-related disability.

Exploring the role of online health information and social media in the illness experience of arthritis-related fatigue: A focus group study.

PURPOSE: Online health information (OHI) and social media have become prominent health resources for people with arthritis-related fatigue. More research is needed to understand how OHI and online social support may influence illness experiences and patient-practitioner relationships in people with arthritis-related fatigue. The present study aimed to explore how OHI and social media shape these experiences by using an inductive qualitative analysis. METHOD: Seven focus groups were conducted with 21 participants aged 28-77 diagnosed with a range of rheumatic diseases. Within the focus groups, participants were asked questions about OHI, online social support and the role of OHI in their health care. The focus groups were recorded, transcribed and analysed using a combination of interpretative phenomenological analysis (IPA) and thematic analysis. RESULTS: The analysis resulted in three themes: (a) how online social support changes illness experiences, (b) communicating fatigue to health professionals using OHI and (c) health care experiences online. These themes provide insight into the ways people with arthritis-related fatigue benefit from online social support, use OHI to support communication with health professionals and how they share health care for arthritis in online spaces. CONCLUSION: This research expanded on previous literature addressing the role of OHI and social media in the illness experience of arthritis-related fatigue. As technology use is increasing, particularly in the current extraordinary environment of social distancing, it is critical to address the role of OHI and social media in health care. In this study, OHI and social media played a prevalent role in the health care of many participants.

Acceptance and commitment therapy for people with rheumatic disease: Existing evidence and future directions.

INTRODUCTION: Despite advances in the management of rheumatic diseases, many patients experience persistent pain and fatigue. Psychological interventions are useful adjunctive treatments, but improvements tend to be small, and progress in this area is needed. The aim of this review was to evaluate the effectiveness of acceptance and commitment therapy (ACT) for the treatment of chronic pain and fatigue in patients with rheumatic disease. METHODS: A systematic literature search was conducted in MEDLINE, EMBASE, and PsycINFO for randomised controlled trials (RCTs) of ACT for the treatment of chronic pain and fatigue in patients with rheumatic disease. Ten RCTs that included people with rheumatic disease were identified, rated for risk of bias, and summarised in terms of effects on relevant outcomes (disability, emotional functioning, pain, and quality of life). RESULTS: Treatment with ACT was associated with improvements in physical and emotional functioning, pain, and quality of life in chronic pain patients. The favourable effects of ACT were evident when compared with those of treatment as usual or active control conditions (e.g., pain education and novel medication). There was consistent evidence to show that ACT is beneficial in improving physical and emotional functioning in patients with fibromyalgia but a lack of evidence pertaining to patients with other forms of rheumatic disease. CONCLUSION: ACT provides benefit for fibromyalgia patients. Further high-quality research is needed to develop ACT interventions for people with inflammatory rheumatic diseases and to evaluate their effectiveness for managing the pain and fatigue associated with these conditions.

Optimising daily diary questionnaires about fatigue, psychological flexibility and well-being: perspectives of people with rheumatic disease.

OBJECTIVES: The aim of this study was to understand the perspectives of people with rheumatic disease have about completing a pilot daily diary questionnaire on fatigue and well-being, with the objective of incorporating these perspectives into future daily studies. METHODS: Twenty-two participants with experience of rheumatic disease-related fatigue attended a focus group and/or an individual interview. Before the focus group or interview, participants completed a one-off quantitative diary about their fatigue and well-being that day. In the focus groups and interviews, participants were asked about their experience completing the questionnaire. Data were analysed using inductive thematic analysis. RESULTS: Three themes were identified. 'Concerns about Misinterpretation and Ambiguity' addressed the elements of the diary questionnaire that were confusing or unclear to participants. 'Desire to Provide Useful and Accurate Information' outlined participants' uncertainty about how to report complex daily experiences. 'Gaining Personal Insight through Diaries' revealed the personal benefits participants gained, particularly the development of insight into their fatigue. CONCLUSIONS: People with rheumatic disease are willing to complete a daily diary questionnaire, but emphasise it is important for diary questionnaires to have clear instructions, questionnaire items and response scales. Addressing these concerns will ensure the reliability and validity of quantitative diary data.

The experience among patients with multiple dental loss as a consequence of treatment for head and neck cancer: A qualitative study.

OBJECTIVES: To explore the experience among patients with multiple dental loss as a consequence of treatment for head and neck cancer. METHODS: Semi-structured qualitative interviews were conducted with a purposive sample of fifteen people with head and neck cancer, who had multiple teeth removed as part of their tumour resection or extracted pre-radiotherapy. The interviews were digitally recorded and transcribed for analysis by two researchers, independently. RESULTS: The interview data were categorised into four themes: 1. Pretreatment experience of being informed that teeth had to be removed, 2. Impact of dental loss post-treatment, 3. Coping with dental loss, and 4. Getting dentures and implants. Patients receiving primary radiotherapy felt the time between being informed of requirement for dental extractions and actual extractions was short. Dental loss was detrimental to all patients in terms of eating, speaking, socially and their intimate lives. CONCLUSIONS: Patients whose primary treatment was surgery, appeared more accepting of dental loss. Whereas, those having primary radiotherapy, there seemed to be a focus on prevention of radiotherapy-induced complications, with limited choices and recognition on post-treatment dental functionality. This study showed the negative impact of dental loss on patients' quality of life. CLINICAL SIGNIFICANCE: Dentists should be aware of the post-treatment implications of dental loss on patients' lives; presenting this, as well as the clinical advantages for extractions, to aid decision-making. Patients should be informed of the lack of conclusive research evidence regarding pre-radiotherapy dental extraction. There should also be clear pathways regarding post-treatment dental-related rehabilitation.

Is avoidance of illness uncertainty associated with distress during oncology treatment? A daily diary study.

OBJECTIVE: The aim of this study was to explore the daily relationship between illness uncertainty, avoidance of uncertainty, well-being and treatment-related distress among patients with cancer receiving treatment with curative intent. It was hypothesised that daily illness uncertainty, daily avoidance of uncertainty and daily treatment-related distress would be negatively associated with daily well-being. It was also hypothesised that daily illness uncertainty and daily avoidance of uncertainty would be positively associated with daily treatment-related distress. DESIGN: Thirty-one patients receiving oncology treatment with curative intent completed a daily diary for seven consecutive days. Data were analysed using multilevel modelling. MAIN OUTCOME MEASURES: Daily illness uncertainty, avoidance of illness uncertainty, treatment-related distress and well-being. RESULTS: As hypothesised, on days when patients with cancer reported heightened treatment-related distress they experienced diminished well-being. And on days when patients reported more experiential avoidance of illness uncertainty, they also experienced heightened levels of treatment-related distress. No other daily associations were significant. CONCLUSION: These findings indicate that patients with cancer experience day-to-day fluctuations in distress and well-being throughout oncology treatment. Avoidance of illness uncertainty-related thoughts and/or emotions are associated with daily distress, but not daily well-being.

"I actually just really need to stop work sometimes": Exploring fatigue-related barriers to employment among people with rheumatic diseases.

PURPOSE: Fatigue is a common symptom of many rheumatic diseases (RDs), but more research is needed to explore the experience of fatigue and its impact on employment among people with RDs. The aim of the present study was to investigate experiences of fatigue, its impact on employment and strategies that people with RD use to continue working. METHOD: Semi-structured in-depth interviews were conducted with five participants with a range of RDs living in New Zealand (three women, two men; aged 45-64 years). All participants were employed part time at the time of the interview. The transcripts were subjected to inductive thematic analysis, led by the first author, who had an RD. RESULTS: Four themes resulted from the analysis: (a) workplace management and coping strategies; (b) the function of positive workplace relationships; (c) barriers to understanding; and (d) collectively improving understanding. These themes act to explain how individuals with RDs in employment believe fatigue to have a bearing on their work, how they manage fatigue at work, how they believe coworkers and employers perceive and manage their fatigue, and what they believe could improve the understanding of fatigue in workplaces. CONCLUSIONS: Individuals with RDs in employment describe fatigue as playing a substantial role in their experiences at work. This research expands on previous literature addressing barriers to employment in those with RDs by specifically addressing the relevance of fatigue. It is imperative to provide information to employers, and guidelines for employees with an RD who are experiencing fatigue should outline appropriate strategies for success at work.

Genetic Diversity among Staphylococcus aureus Isolates Showing Oxacillin and/or Cefoxitin Resistance Not Linked to the Presence of mec Genes.

Methicillin-resistant Staphylococcus aureus isolates lacking mec genes (n = 32), collected from Belgian hospitals, were characterized for their ß-lactamase production and the presence of mutations in pbp genes, the pbp4 promoter, and genes involved in penicillin-binding protein 4 overproduction (gdpP and yjbH). Twelve isolates were ß-lactamase hyperproducers (BHPs), while 12 non-BHP isolates might produce an incomplete GdpP protein. Most isolates showed nucleotide missense mutations in pbp genes. A few isolates also showed mutations in the pbp4 promoter.

CC398 Staphylococcus aureus subpopulations in Belgian patients.

Studies based on genome-wide single nucleotide polymorphisms (SNPs) supported the existence of two subpopulations in clonal complex (CC) 398 Staphylococcus aureus: an ancestral human-adapted clade (HC) and an animal-associated clade (AC). In this study, we have investigated the occurrence of genetic markers that allow discrimination of these subpopulations among CC398 isolates collected during 2014 to 2016 from human patients in Belgium. A collection of isolates was investigated by means of spa-typing and 16S-mecA-nuc PCR. CC398 isolates were classified as belonging to the human or the animal clade by using a canonical SNPs PCR and further studied by antimicrobial susceptibility and the presence of toxins, immune evasion cluster (IEC), and resistance genes. A total of 124 (7.8%) human isolates belonged to CC398. They were grouped into HC (n = 58) or AC (n = 66). The genes erm(T), pvl, chp, and scn were predominantly found in HC-CC398, while AC-CC398 isolates carried more frequently than the mecA, erm(C), tet(K), tet(M), and tet(L) genes. Different combinations of gene profiles were observed according to the clade. CC398 isolates from Belgian patients belonged to different subpopulations including typical HC and AC-isolates. Few HC-strains with mecA and AC-isolates harboring IEC were found. CC398 isolates from Belgian patients belonged to different subpopulations including typical HC and AC-isolates, as well as new emerging subpopulations that underline the ability of this lineage to acquire resistance and virulence genes. Further research is needed to evaluate the emergence of these subpopulations in the clinical setting.

Prospective evaluation of a high multiplexing real-time polymerase chain reaction array for the rapid identification and characterization of bacteria causative of nosocomial pneumonia from clinical specimens: a proof-of-concept study.

The purpose of this study was evaluation of the VAPChip assay based on the "Rapid-Array-PCR-technology" which targets 13 respiratory pathogens and 24 ß-lactam resistance genes directly on respiratory clinical specimens. The first step included analysis of 45 respiratory specimens in order to calibrate and determine the threshold for target genes. The second prospective step involved 85 respiratory samples from patients suspected of nosocomial pneumonia collected in two academic hospitals over an 8-month period. Results of the VAPChip assay were compared to routine methods. The first step showed a large proportion of positive signals for H. influenzae and/or S. pneumoniae. For identification, discrepancies were observed in seven samples. Thresholds were adapted and two probes were re-designed to create a new version of the cartridge. In the second phase, sensitivity and specificity of the VAPchip for bacterial identification were 72.9% and 99.1%, respectively. Seventy (82%) pathogens were correctly identified by both methods. Nine pathogens detected by the VAPChip were culture negative and 26 pathogens identified by culture were VAPChip negative. For resistance mechanisms, 11 probes were positive without identification of pathogens with an antimicrobial-susceptibility testing compatible by culture. However, the patient's recent microbiological history was able to explain most of these positive signals. The VAPChip assay simultaneously detects different pathogens and resistance mechanisms directly from clinical samples. This system seems very promising but the extraction process needs to be automated for routine implementation. This kind of rapid point-of-care automated platform permitting a syndromic approach will be the future challenge in the management of infectious diseases.

A Framework for the Generation of Realistic Synthetic Cardiac Ultrasound and Magnetic Resonance Imaging Sequences From the Same Virtual Patients.

The use of synthetic sequences is one of the most promising tools for advanced in silico evaluation of the quantification of cardiac deformation and strain through 3-D ultrasound (US) and magnetic resonance (MR) imaging. In this paper, we propose the first simulation framework which allows the generation of realistic 3-D synthetic cardiac US and MR (both cine and tagging) image sequences from the same virtual patient. A state-of-the-art electromechanical (E/M) model was exploited for simulating groundtruth cardiac motion fields ranging from healthy to various pathological cases, including both ventricular dyssynchrony and myocardial ischemia. The E/M groundtruth along with template MR/US images and physical simulators were combined in a unified framework for generating synthetic data. We efficiently merged several warping strategies to keep the full control of myocardial deformations while preserving realistic image texture. In total, we generated 18 virtual patients, each with synthetic 3-D US, cine MR, and tagged MR sequences. The simulated images were evaluated both qualitatively by showing realistic textures and quantitatively by observing myocardial intensity distributions similar to real data. In particular, the US simulation showed a smoother myocardium/background interface than the state-of-the-art. We also assessed the mechanical properties. The pathological subjects were discriminated from the healthy ones by both global indexes (ejection fraction and the global circumferential strain) and regional strain curves. The synthetic database is comprehensive in terms of both pathology and modality, and has a level of realism sufficient for validation purposes. All the 90 sequences are made publicly available to the research community via an open-access database.

Mutations at the Ribosomal S10 Gene in Clinical Strains of Staphylococcus aureus with Reduced Susceptibility to Tigecycline.

Mutations on the tip of the extended loop of the ribosomal S10 protein have been associated to tigecycline (TGC) resistance in passaged mutants of different bacteria species. This study described the first two clinical TGC-resistant Staphylococcus aureus isolates with these mutations. One strain (TGC MIC = 2 mg/liter) had a 12-nucleotide deletion affecting residues 56 to 59 (HKYK) of the S10 protein. The second strain (TGC MIC = 1 mg/liter) had amino acid substitutions (K57M and Y58F) previously described in S. aureus passaged mutants.

The role of enjoyment in exercise for people with arthritis: Four different viewpoints from a Q-methodology study.

PURPOSE: There is limited research on the role of enjoyment of exercise among people with arthritis. The aim of the present study was to determine distinct viewpoints on exercise held by people with arthritis, and how enjoyment features in these viewpoints. METHODS: A Q-methodology study was conducted, which involved two interviews with people with rheumatoid arthritis, osteoarthritis or ankylosing spondylitis (aged 20-85 years). In the first interviews, 11 participants helped to create the Q-set, a set of statements reflecting a range of existing views on exercising. In the second interviews, 12 participants (nine of the 11 from the first interviews and three others) ranked the Q-set on a forced quasi-normal distribution of agreement. A Q-method factor analysis was carried out to determine groupings of participants with similar views on exercise. RESULTS: Four groupings were discovered, and defined in terms of rankings of statements and illustrative quotes from the ranking procedure. The first grouping had all changed their exercise habits after diagnosis with arthritis. The second grouping had a shared enjoyment for walking to stay healthy. The third grouping's viewpoints focused on knowledge about how much exercise they should carry out. The fourth grouping shared a sense of importance of being responsible for their health by exercising. CONCLUSION: These findings provide information about the role that enjoyment plays in motivating people with arthritis to exercise, although enjoyment of exercise was not expressed by all participants. People with arthritis who share these viewpoints on exercise enjoyment may require different forms of advice regarding feasible and enjoyable exercise.

In vitro activity of ceftaroline against clinical Staphylococcus aureus isolates collected during a national survey conducted in Belgian hospitals.

OBJECTIVES: The aim of this study was to estimate the in vitro activity of ceftaroline against clinical Staphylococcus aureus isolates collected during national surveillance in Belgian acute-care hospitals. Ceftaroline-resistant isolates were further investigated for their resistance mechanisms. METHODS: From October 2013 to March 2014, 155 laboratories of Belgian acute-care hospitals were invited to send to the National Reference Centre-Staphylococcus aureus (Belgium) up to five non-duplicate S. aureus including three MRSA and two MSSA from hospitalized patients. Isolates were analysed by spa typing, SCCmec typing (for MRSA) and PCR for detection of 16S-mecA-nuc and 16S-mecC. MICs of oxacillin, cefoxitin and ceftaroline were determined by the broth microdilution method. The nucleotide sequences of mecA, native pbp and gdpP genes of isolates with reduced susceptibility to ceftaroline were analysed for the presence of mutations responsible for amino acid substitutions. RESULTS: Ninety-nine percent of isolates, including MRSA (n = 284) and MSSA (n = 131), were susceptible to ceftaroline. Only four MRSA isolates showed resistance to ceftaroline (MIC = 2 mg/L). These four isolates belonged to lineages CC5 (n = 1), CC22 (n = 2) and CC8 (n = 1). Two isolates (CC22 and CC8) carried mutations in mecA, as well as in other pbp genes. The remaining isolates carried mutations in native pbp genes or in gdpP. CONCLUSIONS: This is the first Belgian in vitro survey on ceftaroline activity against S. aureus. This antibiotic showed excellent activity against MRSA and MSSA, and only a few MRSA isolates with resistance were found. Reduced susceptibility to ceftaroline seems a complex phenomenon due to the accumulation of mutations in genes involved in ß-lactam tolerance.
