Advanced practice in radiotherapy across Europe: stakeholders' perceptions of implementation and evolution

INTRODUCTION

Adapting radiotherapy services with workforce innovation using skills-mix or task-shifting optimises resources, supporting current and future demands. Advanced practitioners (APs) work at a different level of practice (beyond initial registration) across four pillars: clinical practice, leadership and management, education, and research. There is limited cross-country research on the advanced therapeutic radiographers/radiation therapists (TR/RTTs), particularly in Europe. This study aimed to investigate European radiotherapy stakeholders' perceptions regarding current and future advanced practice (AP).

METHODS

From June to September 2022, one-to-one online semi-structured interviews were conducted in English, and audio and video were recorded. Full verbatim audio files were independently transcribed and checked by interviewer and interviewees. Braun and Clarke's seven steps guided the thematic analysis (using NVivo).

RESULTS

Thirty-three interviewees working or studying in 16 European countries represented practitioners (n=14), managers (n=6), educators (n=4), professional bodies (n=4), students (n=3), and regulators (n=2). Four overarching themes emerged: "AP drivers and outcomes", "AP challenges vs enablers", "Current vs future AP", "Becoming and being advanced practitioner". Participants identified research as the neglected AP pillar due to a lack of protected time, limited staff skills, no research culture, no funding, workload, and clinical priorities. Interviewees highlighted the importance of consistency in job titles, harmonisation of education models and curricula, definition of AP requirements, and support for all AP pillars through job plans and workforce planning.

CONCLUSION

Neither the profession nor education of TR/RTTs are harmonised across Europe, which is highly reflected in advanced-level practice. Advanced TR/RTTs should work across all pillars, including research, and these should be embedded in master's programmes, including leadership.

IMPLICATIONS FOR PRACTICE

This study highlights a policy gap in the education and practice of APs in radiotherapy.

Demonstrating Agreement between Radio and Fluorescence Measurements of the Depth of Maximum of Extensive Air Showers at the Pierre Auger Observatory

We show, for the first time, radio measurements of the depth of shower maximum (X_{max}) of air showers induced by cosmic rays that are compared to measurements of the established fluorescence method at the same location. Using measurements at the Pierre Auger Observatory we show full compatibility between our radio and the previously published fluorescence dataset, and between a subset of air showers observed simultaneously with both radio and fluorescence techniques, a measurement setup unique to the Pierre Auger Observatory. Furthermore, we show radio X_{max} resolution as a function of energy and demonstrate the ability to make competitive high-resolution X_{max} measurements with even a sparse radio array. With this, we show that the radio technique is capable of cosmic-ray mass composition studies, both at Auger and at other experiments.

Dysphagia and pulmonary complications in acute cerebrovascular disease: A retrospective observational study

INTRODUCTION

Dysphagia is a common post-stroke complication, which may result in serious pulmonary sequelae. Early detection of dysphagia and aspiration risk can reduce morbidity, mortality and length of hospitalization.

OBJECTIVES

This study aims to identify association between dysphagia and acute cerebrovascular disease, and evaluate the prevalence and impact of pulmonary complications on readmissions and mortality.

MATERIAL AND METHODS

Retrospective observational study based on 250 clinical records of patients with acute cerebrovascular disease: clinical history, neurological examination, imaging and Gugging Swallowing Screen in the first 48h. Patients were followed for 3 months via medical records to estimate 3-month mortality and readmissions.

RESULTS

Out of 250 clinical records analyzed, 102 (40.8%) were evaluated for dysphagia. The prevalence of dysphagia was 32.4%. The risk was higher in older patients (p<0.001), in severe stroke (p<0.001) and in the hemorrhagic subtype (p=0.008). An association was found with dysarthria and aphasia (p=0.003; p=0.017). Respiratory tract infections occurred in 14.4% of all patients (GUSS group 11.8% versus no GUSS group 16.2%), and in 75% of those with severe dysphagia (p<0.001). Mortality at 3 months was 24.2% in dysphagic patients, especially high in the severe dysphagia group (75%, p<0.001).

CONCLUSIONS

The type of cerebrovascular disease, NIHSS and GCS scores, age, dysarthria, and aphasia were significant associated factors to dysphagia. The prevalence of respiratory tract infections was higher in patients with no GUSS record, and no statistical significance was observed in related readmissions. Mortality at 3 months was superior in the severe dysphagia group.

Dose-Effect of Proton and Photon Craniospinal Irradiation on Vertebral Growth in Pediatric Patients with Medulloblastoma

PURPOSE/OBJECTIVE(S)

Craniospinal irradiation (CSI) directly damages vertebral growth plates causing skeletal dysplasia leading to reduced height in pediatric long-term survivors. The objective of this study is to quantify the adjusted effect of CSI on standing and sitting height by radiation dose and modality in children.

MATERIALS/METHODS

Two hundred sixty-five patients (M/F 169/96) were treated at a single institution on a clinical and molecular risk-directed trial for medulloblastoma (NCT01878617) using proton or photon therapy. Three CSI dose regimens were evaluated: 15 Gy (n = 31), 23.4 Gy (n = 103), ≥36 Gy (n = 131). Vertebral body dose was limited to 18-20 CGE for 23.4 Gy or 36 Gy proton therapy. All patients received post-CSI protocol-specified chemotherapy. Non-parametric tests were applied for baseline patient comparison. Changes in growth over time were calculated using random coefficients models using patient-specific intercepts and slopes. Dose-effects were modeled for ages 5, 10, and 18 years.

RESULTS

Age at CSI and race were similar between the three dose levels. Females most often received 23.4 Gy and males ≥36 Gy (p = 0.001). Higher CSI doses were associated with photon therapy (p<0.001). Median follow-up was 3 years (range 0.1-7.1). Annual growth rate was significantly different between 15 Gy (3.66 cm/year) and the higher dose levels of 23.4 Gy (2.81 cm/year, p = 0.0389) and ≥36 Gy (2.46 cm/year, p = 0.0032). Lower annual growth rate in females (vs. males, p = 0.0331) was observed in models for those aged 5 (-0.17 cm/year), 10 (-0.35 cm/year), and 18 years (-0.62 cm/year). In multivariate analysis, modelled annual growth rate was dose-dependent at ages 5 and 10 years. The differences were, respectively, 1.68 cm/year between 15 and 23.4 Gy (p = 0.0005) and 0.98 cm/year between 23.4 and ≥36 Gy (p = 0.0002), and 1.13 cm/year between 15 and 23.4 Gy (p = 0.0002) and 0.68 cm/year between 23.4 and ≥36 Gy (p = 0.0003). Radiation modality did not impact standing height over time significantly. Annual sitting height growth was 2.34, 1.67 and 1.1 cm/year for the three dose levels (p<0.0001-0.001). In the multivariate model, a 5-year-old receiving 15 or 23.4 Gy had similar annual sitting height growth, but not when 23.4 Gy was compared to ≥36 Gy (0.83 cm/year, p<0.0001). In a separate model for a patient aged 10 years, there was a difference comparing all CSI regimens (0.81 cm/year, p<0.0001, 15 vs 23.4 Gy; 0.54 cm/year, p = 0.0002, 23.4 vs ≥36 Gy). Sitting height growth was affected by CSI dose at age 18 years, with a difference of 2.2 cm/year between 15 vs 23.4 Gy (p = 0.0013), and no difference between 23.4 and ≥36 Gy.

CONCLUSION

Annual growth rates show a dose-response relationship, independent of treatment modality. A dose-response in sitting height growth rate is seen at any age, while the annual standing height growth rate was only affected by CSI dose in 5- and 10-year-olds. While all CSI doses had a significant impact on the annual standing height, sitting height growth rates approximated normal values for those treated with a low CSI dose.

A Survey of Submission and Review Standards across Clinical Radiation Oncology and Medical Physics Journals: Devising the Optimal Criteria for Reproducibility and Sustained Impact

PURPOSE/OBJECTIVE(S)

Publishing and editorial policies differ substantially across the Radiation Oncology (RO) and Medical Physics (MedPhys) compendium of journals. Adoptance of modern standards in scientific publishing and data sharing have the potential to improve the impact and reliability of the RO literature.

MATERIALS/METHODS

We characterized the editorial, authorship and peer reviewer policies of various prominent clinical RO (N = 16) and medical physics (N = 9) peer-reviewed journals affiliated with professional societies for characteristics that are associated with improved reproducibility and rigorous review. A combination of tools including Enhancing the QUAlity and Transparency Of health Research (EQUATOR), Findability, Accessibility, Interoperability, and Reuse (FAIR), and Quality Output Checklist and Content Assessment (QuOCCA) principles were used to quantify the value and reproducibility of journal policies. Cohen's kappa coefficient was utilized to assess agreement between reviewers. Components of the above tools were regressed against various scientometric indices (H-index, IF, etc.) to identify factors that are associated with perceived relative importance within the field.

RESULTS

Reviewer agreement (κ) for scientometric indices was highest (1.0) for criteria for statistical review and data submission standards and lowest (-0.246) for various submission checklists. Data availability statements were endorsed (44%) or required (31%) in a higher proportion of RO journals relative to MedPhys journals (44%, 0% respectively). Data repository submission was required in <10% of journals. FAIR adoptance was poor (31%, 22%) in RO and MedPhys journals. ≥1 EQUATOR guideline checklist was endorsed or required in 76% of journals. While there were no glaring differences in editorial policies between RO and MedPhys journals, there was substantial heterogeneity of scientometrics evaluating the rigor of data submission, reproducibility standards, and statistical review criteria. Linear regression of journal impact factors indicated a predictive relationship between FAIR adoption standards, use of EQUATOR checklists, and more rigorous statistical method submission criteria.

CONCLUSION

The present review documented and confirmed significant variation in submission, review, and publication policies across RO and MedPhys journals. Established scientometric standards, FAIR principle adoptance, and more rigorous statistical methodology were predictive of increasing journal impact factor.

Patient-reported perspectives of therapeutic radiographers when undergoing radiotherapy: A European multi-centre study

INTRODUCTION

Radiotherapy is delivered almost exclusively by therapeutic radiographers/radiation therapist (RTTs). Patient's perspectives of RTTs affect levels of trust and confidence in the profession and can have a significant impact on overall radiotherapy experience. The study reports patients' perspectives of RTTs from their experience of undergoing radiotherapy. Four partner sites collaborated in this research and included Malta, Poland, Portugal, and the UK (lead site).

METHODS

A survey was developed to gather information from patients receiving radiotherapy or who had had radiotherapy within the previous 24 months. Participants ranked their responses to 23 statements relating to person-centred care on a 5-point scale of 1 (strongly disagree) to 5 (strongly agree). Mann-Whitney or Kruskal Wallis tests were applied to test differences in responses to 5 key statements for patient characteristics including gender, age group, diagnosis, country, time spent with RTTs and number of fractions remaining at survey completion.

RESULTS

Three hundred and forty-seven surveys are included. Patients report a positive perception of RTTs (95.4% agree with 'I feel cared for'). Statistically significant differences in responses were found between gender, diagnosis, country, time spent with RTTs and fractions of radiotherapy remaining. Patients who had more time with RTTs and completed their surveys during radiotherapy had a more positive perception of RTTs.

CONCLUSION

This study suggests that sufficient time with RTTs is key to ensuring a positive radiotherapy patient experience. RTTs being attentive, understanding, and informative are most predictive of a positive overall patient experience. Timing of survey completion can influence responses.

IMPLICATIONS FOR PRACTICE

RTT education programmes should incorporate training on person-centred care at all levels. Further research into patient experience of RTTs is warranted.

Modulating Influence of State Anxiety on the Effect of Midazolam on Postsurgical Pain

Anxiety contributes to postsurgical pain, and midazolam is frequently prescribed preoperatively. Conflicting results have been described concerning the impact of midazolam on pain. This study aims to evaluate the effect of systemic midazolam on pain after open inguinal hernia repair, clarifying its relationship with preoperative anxiety. A prospective observational cohort study was conducted in three Portuguese ambulatory units between September 2018 and March 2020. Variable doses of midazolam were administered. Postsurgical pain was evaluated up to three months after surgery. We enrolled 306 patients and analyzed 281 patients. The mean preoperative anxiety Numeric Rating Scale score was 4 (3) and the mean Surgical Fear Questionnaire score was 22 (16); the mean midazolam dose was 1.7 (1.1) mg with no correlation to preoperative anxiety scores. Pain ≥4 was present in 67% of patients 24 h after surgery and in 54% at seven days; at three months, 27% were classified as having chronic postsurgical pain. Preoperative anxiety correlated to pain severity at all time points. In multivariable regression, higher midazolam doses were associated with less pain during the first week, with no apparent effect on chronic pain. However, subgroup analyses uncovered an effect modification according to preoperative anxiety: the decrease in acute pain occurred in the low-anxiety patients with no effect on the high-anxiety group. Inversely, there was an increase in chronic postsurgical pain in the very anxious patients, without any effect on the low-anxiety group. Midazolam, generally used as an anxiolytic, might impact distinctively on pain depending on anxiety.

A111 CLINICAL AND PATHOLOGICAL OUTCOMES BETWEEN WATER EXCHANGE AND AIR INSUFFLATION USING NON-SEDATED EXTENDED FLEXIBLE SIGMOIDOSCOPY FOR AVERAGE RISK COLORECTAL CANCER SCREENING: PRELIMINARY FINDINGS FROM A RANDOMIZED CONTROL TRIAL

Background

Colorectal cancer (CRC) is Canada's third most common cancer type and represents approximately 11% of all cancer deaths. While sedated colonoscopy or flexible sigmoidoscopy (FS) continues to be considered for CRC screening, these modalities have limitations and risks. Another unevaluated screening modality, known as an extended FS (EFS), attempts to capitalize on the benefits of a FS while minimizing the risks involved with a sedated colonoscopy. EFS provides a scope-based examination up to the splenic flexure and then attempts to examine beyond, often to the point of the caecum. Providing the option for EFS may produce improvements in the patient experience and performance, which may improve the feasibility of using scope-based screening more broadly in screening programs.

Purpose

To determine the extent non-sedated EFS using the water exchange method (WE) is associated with a complete colon examination compared to the traditional air insufflation (AI) method using CO2 in an average-risk screening population.

Method

This randomized control trial included 90 non-sedated participants, screened by trained general surgery and gastroenterology clinicians at Kelowna General Hospital, British Columbia, Canada, using two different scope insufflation techniques, WE and AI. The primary outcome of interest was the cecal intubation rates (CIR), while secondary outcomes included the adenoma detection rate (ADR) and reported pain scores. Other metrics, such as patient satisfaction rates, sessile serrated adenoma detection rates (SSADR), and serrated lesion detection rates (SLDR) were also recorded.

Result(s)

The demographic characteristics between the WE and AI groups were statistically similar, with the mean age of participants being 58 and 57, respectively. During the study period, four endoscopists performed the EFS. There were higher initial satisfaction rates in the WE group vs the AI (95% vs 77%, satisfaction of ≥ 9/10 p = 0.028). CIR and ADR were similar between the WE and AI group (CIR = 93% vs 91%, p = 0.710), (ADR = 40% vs 34%, p = 0.660). The SSADR and SLDR were also similar between the WE and AI group (SSADR = 21% vs 14%, p = 0.408), (SLDR = 42% vs 36%, p = 0.528).

Conclusion(s)

EFS without sedation using either technique exceeds quality benchmarks recommended for sedated screening colonoscopy while maintaining adequate patient safety and comfort. The WE method optimizes a patient's overall experience making a strategy of average risk colorectal cancer screening with non-sedated WE EFS feasible.

Advanced practice roles amongst therapeutic radiographers/radiation therapists: A European survey

INTRODUCTION

Advanced Practice (AP) roles in Radiotherapy (RT) over time are variable, often locally developed and not underpinned by professional standards which leads to conceptual and practical gaps. This study aimed to assess AP roles amongst Therapeutic Radiographers/Radiation Therapists (TR/RTTs) and identify educational gaps for this level across Europe.

METHODS

An anonymous online survey was designed, validated, and distributed across Europe. Convenience sampling was used to recruit advanced TR/RTTs practitioners or TR/RTTs working in AP roles. Descriptive analysis from closed questions and thematic analyses from open questions are reported.

RESULTS

A total of 272 responses were obtained, of which 189 eligible participations were from 21 European countries. 42% of respondents acknowledged additional education required to perform AP, and 25% reported a minimum of five years of RT practice to perform AP roles/tasks. There is a trend to work more on the clinical practice domain with a low percentage of working time allocated to research. Inconsistency was found in job titles, scopes of practice, and educational backgrounds across and even within countries. Education needs regarding knowledge about image-guided and adaptive RT, multimodal imaging and technologies, and advanced treatment planning were found. Training needs on leadership and management skills and clinical site-specific expertise were identified.

CONCLUSION

This study clearly shows a gap in education support, a need for standardisation in job titles and scopes of practice across Europe.

IMPLICATIONS FOR PRACTICE

As the first large-scale assessment of current AP roles and educational support amongst TR/RTTs across Europe, this study recommends the establishment of governance structure and role regulation. It also informs the curricula for master programmes to align the education with current and future practice.

The relationship between loneliness and healthy aging indicators in Brazil (ELSI-Brazil) and England (ELSA): sex differences

OBJECTIVES

This study aimed to estimate five harmonized healthy aging indicators covering functional ability and intrinsic capacity among older women and men from Brazil and England and evaluate their association with loneliness.

STUDY DESIGN

This was a cross-sectional study.

METHODS

We used two nationally representative samples of men and women aged ≥60 years from the Brazilian Longitudinal Study of Aging (ELSI-Brazil) wave 2 (2019-2021; n = 6929) and the English Longitudinal Study of Aging wave 9 (2018-2019; n = 5902). Healthy aging included five separate indicators (getting dressed, taking medication, managing money, cognitive function, and handgrip strength). Loneliness was measured by the 3-item University of California Loneliness Scale. Logistic regression models stratified by sex and country were performed.

RESULTS

Overall, age-adjusted healthy aging indicators were worse in Brazil compared with England for both men and women. Considering functional ability, loneliness was negatively associated with all indicators (ranging from odds ratio [OR] = 0.26, [95% confidence interval (CI) 0.13-0.52] in English men regarding the ability to take medication to OR = 0.49 [95% CI 0.27-0.89] in Brazilian women regarding the ability to manage money). Considering intrinsic capacity, loneliness was negatively associated with a higher cognitive function (OR = 0.72; 95% CI 0.55-0.95 in English women) and a higher handgrip strength (OR = 0.61; 95% CI 0.45-0.83 in Brazilian women). Lonely women demonstrated lower odds of a higher number of healthy aging indicators than men in both countries.

CONCLUSIONS

Country-specific social environments should be targeted by public policies to decrease loneliness and promote healthy aging later in life.

Limits to Gauge Coupling in the Dark Sector Set by the Nonobservation of Instanton-Induced Decay of Super-Heavy Dark Matter in the Pierre Auger Observatory Data

Instantons, which are nonperturbative solutions to Yang-Mills equations, provide a signal for the occurrence of quantum tunneling between distinct classes of vacua. They can give rise to decays of particles otherwise forbidden. Using data collected at the Pierre Auger Observatory, we search for signatures of such instanton-induced processes that would be suggestive of super-heavy particles decaying in the Galactic halo. These particles could have been produced during the post-inflationary epoch and match the relic abundance of dark matter inferred today. The nonobservation of the signatures searched for allows us to derive a bound on the reduced coupling constant of gauge interactions in the dark sector: α_{X}≲0.09, for 10^{9}≲M_{X}/GeV<10^{19}. Conversely, we obtain that, for instance, a reduced coupling constant α_{X}=0.09 excludes masses M_{X}≳3×10^{13}  GeV. In the context of dark matter production from gravitational interactions alone, we illustrate how these bounds are complementary to those obtained on the Hubble rate at the end of inflation from the nonobservation of tensor modes in the cosmological microwave background.

Pitfalls of cubital electrical nerve stimulation for neuromuscular transmission monitoring: A case report of familial amyloid polyneuropathy

Transthyretin familial amyloid polyneuropathy (FAP) is a rare autosomal dominant disease that provokes systemic deposition of amyloid. It affects the nervous system and it is characterized by progressive sensory, motor, and autonomic neuropathy. Patients with FAP often require surgery and anesthetic care for hepatic transplantation and cardioverter-defibrillator/pacemaker implantation. Peripheric neuropathy is a common finding, but there are no reported cases of its interference with anesthetic neuromuscular transmission monitoring. We report a case of a FAP patient where lack of awareness and distracting factors led to misinterpretation of neuromuscular monitoring and unnecessary sedation and ventilation in the post anesthetic care unit. FAP may interfere with the usual cubital nerve neuromuscular monitoring. Anesthesiologists should be aware of potential neuromuscular compromise to find the best monitoring location for each patient. Sugammadex was safe and reliable in the antagonism of rocuronium neuromuscular blockade in this case, despite the lack of adequate quantitative monitoring.

Aortic valve calcium score: does it correlate with mean transaortic gradient?

Introduction

Aortic valvular calcium score (AVCS) is useful in patients with aortic stenosis for whom echocardiography was not conclusive in grading its severity. Transcatheter aortic valve implantation (TAVI) is an established procedure of treatment in symptomatic severe AS. The burden of aortic valve calcification has been associated with some TAVI related complications (as perivalvular leaks), but at the same time it is well accepted that some degree of calcification is needed to ensure stable anchoring of the prosthesis to the aortic annulus.

Purpose

To assess if there is a correlation between aortic valve calcium score and mean transvalvular gradient 6 months after TAVI – is a higher AVCS correlated with lower mean transaortic gradient after TAVI?

Methods

We performed a single-center, retrospective cohort study including patients who underwent TAVI with a preoperative standardized contrast enhanced MSCT with AVCS available. Clinical and echocardiographic data were collected previously to TAVI (pre-TAVI) and at 6 months follow up (6M-FUP).

Results

A total of 187 patients were included, with 54% female and a mean age of 79.4±9.0 years old. Most patients had tricuspid aortic valve (95.7%); 5 patients had aortic bicuspidy and 3 had aortic valve bioprothesis. Concerning the valve type, 73.3% had new generation prosthesis and the main valve used was the CoreValve Evolut Pro (33.7%). Also, 38,5% needed balloon pre-dilation before TAVI. The mean pre-TAVI aortic transvalvular maximum and mean gradients were 76.5±23.2 mmHg and 48.3±15.5 mmHg, respectively; mean aortic valve area was 0.75±0.16 cm2. The mean AVCS was 2851±1524 AU (Agaston Units); 81.2% of women had AVCS&gt;1300 AU and 74.4% men had AVCS &gt;2000 AU. Comparing transvalvular aortic gradients previously and 6M-FUP after TAVI, there was an average differential of maximum gradient of 61±22 mmHg and of mean gradient of 40±15 mmHg. A negative and weak correlation was found between the AVCS and the maximum gradient (pearson coefficient of −0.181, p=0.02) and between mean gradient at 6M-FUP (pearson coefficient of −0.191, p=0.014).

Discussion and conclusion

AVCS is a significant predictor for death, stroke and perivalvular leaks after TAVI. On the other hand, high AVCS is associated with better seating in the native annulus during deployment. Nevertheless, high AVCS did not strongly correlated with mean transaortic gradient 6 months after TAVI.

Transthyretin amyloid cardiomyopathy: a 2-year single-centre experience

Background

Transthyretin Amyloid Cardiomyopathy (ATTR-CM) is an under-diagnosed condition often presenting with Heart Failure (HF). We aimed to assess a cohort of patients with ATTR-CM and HF, focusing on the centre strategies to identify new cases, prognosticate and tailor treatment.

Methods

We conducted an all-comers single-centre prospective registry of consecutive patients with HF due to ATTR-CM followed in our centre from November 2019 to 2021. As per site protocol, diagnosis is established according to the algorithm by Gilmore et al. and all patients are assessed in our HF outpatient clinic at least twice yearly with systematic electronic chart data collection. We evaluated disease-modifying treatment and compliance with the current European Guidelines and CHAD-STOP management. A summary of this program is presented in the central figure.

Results

Overall, 60 patients were included (mean age 83±7 years; 80% male). ATTR-CM was confirmed by the non-invasive algorithm in all but 8 patients, in whom endomyocardial biopsy was positive. Of those undergoing genetic testing (n=30), 7 (23%) presented with the hereditary form of ATTR-CM (4 Val50Met and 3 Val142Ile mutations). The initial presentation was most often HF (n=43), atrial fibrillation (n=9), or “incidental” myocardial uptake on 99mTc-HMDP bone scintigraphy (grade 2) performed for cancer staging (n=5). Beta-blockers were reduced or stopped in 40 (67%) patients, all of whom improved in NYHA class and/or NT-proBNP (&gt;30% reduction) at 1–3 months. Tafamidis 61mg was started in 22 patients and 15 more currently await approval. Those initiated on or referred to tafamidis 61mg (n=37) had less severe HF, as per NYHA (class I-II – 94 vs. 50%, p=0.033) and performance status (e.g. Karnofsky score 80–100 – 79 vs. 21%, p=0.010). Of those already on tafamidis (n=22), NYHA class remained stable or improved in all but 1 patient. In the year following vs. preceding treatment there was 2 vs. 3 total HF hospitalizations. No drug-related severe adverse events were reported. Over a 2-year follow-up, 14 (23.3%) patients died, of whom 1 was on tafamidis (compassionate use for 19 months).

Conclusions

ATTR-CM recognition is improving in our dedicated rare disease program, possibly due to the implementation of several alert pathways. The identification of the disease at an earlier stage allows targeted treatment, compliant with the recommendations. Nonetheless, the rarity of this disease and the required expertise for its optimal management argues in favour of a national strategic plan based on referral centres for ATTR-CM.

Percutaneous valve commissurotomy in mitral stenosis patients: a 20 years follow-up

Background

Percutaneous valve commissurotomy (PMC) is a viable alternative to mitral valve surgery in the treatment of patients with clinically significant mitral stenosis (MS). Although rheumatic MS incidence has decreased in developed countries, it remains a prevalent healthcare problem in Cardiology clinics

Purpose

To evaluate the early and long-term results of PMC in patients with rheumatic MS and to compare long-term events between patients with and without pulmonary hypertension (PH).

Methods

We retrospectively analysed all consecutive patients between 1991 and 2008 with clinically significant rheumatic MS undergoing PMC. Clinical and echocardiographic data were collected at baseline and during long-term follow-up. MACE was a composite of adverse events defined as all-cause mortality, mitral valve re-intervention or hospitalization for a cardiovascular cause.

Results

A total of 124 patients were enrolled: 87% were female, with a mean age at the time of repair of 46±11 year-old and a mean follow-up of 20±6 years. Before the procedure, 34% were in NYHA class ≥ III and 81% had a Wilkins score ≤8; all patients had preserved biventricular systolic function, 83% presented PH, mean transvalvular gradient (TVG) and mitral valve area (MVA) were 12.8 mmHg and 1.0 cm2, respectively. Most of the procedures were successful (91%) and without complications (94%), with a mean MVA improvement of 0.9 cm2 and reduction of 8.5 mmHg in TVG and 9.7 mmHg in pulmonary artery systolic pressure (PASP) after PMC.

During long-term follow-up, 42% of patients were submitted to re-intervention (most of them surgically) and 24% died. In patients non-submitted to re-intervention, TVG and PASP remained similar with early post-procedure evaluation (p=0.109 and p=0.777, respectively), while MVA reduced over time, yet still statistically superior to baseline MVA (1.6 cm2 vs 1.0 cm2, p&lt;0.001). Concerning time-to-event analysis, approximately 80% of patients kept uneventful after 10 years; after 30 years, more than 20% continued MACE-free and approximately 50% were alive. Regarding PH presence at time of PMC, there was no significant difference in MACE events and all-cause mortality between the two groups (Log Rank, p=0,846 and p=0.661, respectively).

Conclusion

PMC was safe and effective in clinically significant rheumatic MS. After a long-term follow-up patients maintained the reduction in TVG and PASP and a smaller but significative improvement in MVA. Most of the patients were free from adverse events after 10 years and half were alive after 30 years. There was no difference in all-cause mortality and in a composite of all-cause death, mitral valve re-intervention or cardiovascular hospitalization concerning PH presence.

Reduced 3D-left atrium ejection fraction predicts development of atrial fibrillation in patients with hypertrophic cardiomyopathy

Introduction

Atrial fibrillation (AF) is the most common sustained arrhythmia in hypertrophic cardiomyopathy (HCM), occurring in approximately 25% of patients, related to left atrial (LA) dilatation and remodeling. HCM patients who develop AF have increased risk of HCM-related death, functional impairment, and stroke. Accurate risk stratification for AF in this population is crucial as contemporary treatments are highly successful.

Purpose

To assess if new echocardiographic parameters can predict the development of AF in HCM patients.

Methods

HCM patients who underwent comprehensive echocardiographic examination during 2011 were followed and checked for “de novo” AF until November 2021. We searched for associations between AF development and novel echocardiographic parameters such as LA Volume index, Left Atrioventricular Coupling Index (LACI, as LAVI/a'), 3D LA volumes and 3D LA ejection fraction (3D-LAEF).

Results

A total of 43 patients were included, with 62.8% male and mean age 56,1±6,2 years old. 55.8% had the septal asymmetric HCM type and mean LV mass was 326±127g. Mean LA diameter and biplane 2D volume was 46±7 mm and 78±37 mL, respectively. 11.6% of patients already had AF. During a median follow-up of 9.4 years, the incidence of “de novo” AF was 31,6%. Within the total 17 patients with AF, 35,2% took warfarin and the remaining direct oral anti-coagulation. No stroke was documented. There were 3 deaths (mortality rate of 7,0%), none from cardiac causes.

No association was found between AF development and LAVI, LACI or 3D LA volumes. We only found a statistically significant difference regarding 3D-LAEF, which was lower in patients who developed AF compared with those without AF (26±12% VS 39±19%, p=0.04).

Binary logistic regression analysis found that reduced 3D-LAEF predicts the development of AF (p=0.019, odds ratio [OR] 2.6, 95% confidence interval [CI] 1.0 to 1.1). The area under a receiver operating characteristic curve using 3D-LAEF as a predictive marker for AF development in HCM patients was 0.743 (p=0.004). When the cut-off value of 3D-LAEF was set at 34,5%, the sensitivity and specificity for AF diagnosis were 66% and 86%, respectively.

Conclusion

In our study, 3D LAEF predicted the development of AF in HCM patients – this may be a useful tool to identify patients at high risk of future AF who may benefit from more intensive rhythm monitoring and a lower threshold for oral anticoagulation.

Long-term success in percutaneous valve commissurotomy – is Wilkins score over 9 a definitive limit?

Background

Percutaneous valve commissurotomy (PMC) is an established treatment in patients with significative mitral stenosis (MS). Although rheumatic MS incidence has decreased in the last century, it remains a prevalent pathology worldwide. The Wilkins score (WS) is a reference in echocardiographic assessment of MS; a score ≤8 is considered a predictor of treatment success and score between 9 and 11 is a “grey zone” (WGZ) in which doubts persists regarding PMC success.

Purpose

To evaluate the early and long-term results of PMC in patients with rheumatic MS and to compare long-term events between patients with WS ≤8 and patients in WGZ.

Methods

We retrospectively analysed all patients between 1991 and 2008 with significative rheumatic MS undergoing PMC. Data were collected at baseline and during long-term follow-up. M ACE was defined as a composite of all-cause mortality, mitral valve re-intervention or cardiovascular hospitalization.

Results

In our cohort, 124 patients were included. Most were female (87%), mean age at the time of repair was 46±11 year-old and mean follow-up was 20±6 years. Before the procedure, 81% had WS ≤8 and 19% were in WGZ. Both groups had similar baseline characteristics, namely age at first intervention, NYHA class and follow-up time. All patients had preserved biventricular systolic function, 83% presented PH, mean transvalvular gradient (TVG) and mitral valve area (MVA) were 12.8 mmHg and 1.0 cm2, respectively. Most of the procedures were successful (91%) and without complications (94%). Mean MVA improvement was similar in both groups [0.9 cm2 in WS ≤8 and 0.8 cm2 in WGZ, t(102)=0.173, p=0.863]; there was also no significative difference in TVG and PASP reduction after PMC. During long-term follow-up, re-intervention and mortality occurred in 40% and 23% in WS ≤8 and in 50% and 29% in WGZ, respectively, and none of these differences was statistically significant (p=0.389 and p=0.544, respectively). Concerning time-to-event analysis, approximately 80% of patients kept uneventful and &gt;90% alive after 10 years in both groups and no significant difference in M ACE events and all-cause mortality between WS ≤8 and WGZ was observed (Log Rank, p=0,419 and p=0.950, respectively).

Conclusion

PMC was safe and effective in clinically significant rheumatic MS in both WS ≤8 and WS 9–11, with similar MVA improvement. After 10 years, approximately 80% of patients were MACE-free and &gt;90% alive in both groups. There was no difference in all-cause mortality and in a composite of all-cause death, mitral valve re-intervention or cardiovascular hospitalization concerning WS groups.

Patient delay in acute myocardial infarction: a long journey still ahead

Background

It is overly known that time delays in acute myocardial infarction (AMI) strongly influence its outcomes. Patient delay (PD) is repeatedly pointed out as the longer one in this context, as well as it is the less modifiable one by organizational measures. Therefore, it is crucial to understand the reasons for longer PD in our population, to define proper strategies to improve PD and, ultimately, AMI-outcomes.

Methods

In this six-month prospective study of patients (pts) admitted in a tertiary hospital due to type-1 AMI, 194 pts were consecutively enrolled between May and October 2021. Data was based on a pts well-structured interview within 48h after admission and review of medical records.

Results

Our work spotted several aspects significantly influencing PD in AMI context (Figure 1). Concerning pts cardiovascular background, a trend towards a shorter PD was found in pts with at least one cardiovascular risk factor (CVRF) (p=0,08) and with a previous history of AMI (p=0,08). Regarding clinical presentation, a significantly shorter PD was found in pts presenting with associated symptoms (p=0,02), higher chest pain intensity (chest pain intensity ≥7 vs &lt;7 in a 0–10 scale; p=0,03) and symptoms onset on weekdays rather than weekends (p=0,003). Regarding pts knowledge, significant differences were found when pts recognized their symptoms as AMI, presenting a shorter PD in this context (p=0,006). Curiously, pts ability to correctly identify AMI symptoms, when asked, or to acknowledge their CVRF (when present), did not influence PD. Considering sociodemographic factors, higher incomes (p=0,03) and non-rural residence (p=0,03) significantly translated into shorter PD. No differences were found in PD according to pts age, gender or educational level. After this initial univariate analysis, multiple linear regression was performed to identify possible predictors of PD. Four variables were identified: pts ability to recognize their symptoms as AMI (β −0.199; 95% CI: −277 to −34,87; p=0.012), living in a non-rural residence (β 0.154; 95% CI: 0.12–161.44; p=0.05), presenting associated symptoms (β −0.194; 95% CI: −257.43 to −28.84; p=0.014) and occurrence of symptoms on weekdays (β 0.170; 95% CI: 12.73–259.49; p=0.031) predicted shorter patient delays.

Conclusion

Our study clearly points to the need for increasing public awareness and educational measures, mainly in pts living in rural areas, in order to: 1) Improve pts knowledge about AMI symptoms, clarifying that atypical symptoms can happen; 2) Reinforce the importance of shortening AMI time delays, clearly explaining the concept “time is muscle”.

20 year-follow up of mitral stenosis patients after percutaneous valve commissurotomy: moderate disease of other valves as predictor for re-intervention

Background

Percutaneous valve commissurotomy (PMC) is a viable alternative to mitral valve (MV) surgery in the treatment of patients with clinically significant mitral stenosis (MS). About 40% of patients treated with PMC will require at least one reintervention (either PMC or MVS) along time.

Purpose

To evaluate the long-term results of PMC in patients with rheumatic MS.

Methods

We retrospectively analysed all consecutive patients between 1991 and 2008 with clinically significant rheumatic MS undergoing PMC. Clinical and echocardiographic data were collected at baseline and during early and long-term follow-up. MACE was a composite of adverse events defined as all-cause mortality, MV re-intervention or cardiovascular hospitalization.

Results

A total of 124 patients were enrolled: 108 (87%) were female, with a mean age at the time of PMC of 46±11 years.

At baseline, 34% patients were in NYHA class ≥ III and 81% had a Wilkins score ≤8; all patients had preserved biventricular systolic function and 83% presented pulmonary hypertension. Regarding associated valve disease, 46 patients had mild tricuspid regurgitation (TR), 19 mild aortic regurgitation (AR), 14 moderate IT and 5 moderated AR.

Most of the procedures were successful (91%) and without complications (94%), with median improvement in MV area of 0.9 cm2 (IQR 0.5) and median reductions in mean transmitral gradient (MTG) of 6 mmHg (IQR 6) and in pulmonary artery systolic pressure (PASP) of 8 mmHg (IQR 10) early after PMC.

During the mean follow-up of 20±6 years, 52 (42%) of patients had MV re-intervention (86% surgery and 14% re-PMC), 37 (30%) were hospitalized and 30 (24%) died. Concerning time-to-event analysis, approximately 80% of patients kept MACE-free after 10 years; after 30 years, more than 20% continued MACE-uneventful, approximately 50% were alive and about 45% were free from re-intervention.

Considering patients submitted to surgical re-intervention, 9 underwent MV valvuloplasty and the others MV replacement with mechanical (32) or biological prothesis (11). At the same procedure, 23 patients were submitted to tricuspid annuloplasty, 9 to other valve replacement and one to coronary artery bypass graft.

Using Cox regression, we found that the presence of moderate disease of other valves at PMC time was associated with a 2.3-fold greater rate of re-intervention compared to patients with none or mid disease of other valves (HRcrude 2.3; 95% IC 1.221–4.331, p=0.017). After adjusting for the success of the PMC and for mitral regurgitation after PMC, the observed effect remained significant (HRadjusted = 2.7; 95% CI 1.417–5.233, p=0.003).

Conclusion

PMC was safe and effective in clinically significant rheumatic MS. Most of the patients were free from adverse events after 10 years and half were alive after 30 years. Still, about 40% required re-intervention, with moderate disease of other valves as its independent predictor.

Digital skills of therapeutic radiographers/radiation therapists - Document analysis for a European educational curriculum

INTRODUCTION

It is estimated that around 50% of cancer patients require Radiotherapy (RT) at some point during their treatment, hence Therapeutic Radiographers/Radiation Therapists (TR/RTTs) have a key role to play in patient management. It is essential for TR/RTTs to keep abreast with new technologies and continuously develop the digital skills necessary for safe RT practice. The RT profession and education is not regulated at European Union level, which leads to heterogeneity in the skills developed and practised among countries. This study aimed to explore the white and grey literature to collate data on the relevant digital skills required for TR/RTTs practice.

METHODS

An exhaustive systematic search was conducted to identify literature discussing digital skills of TR/RTTs; relevant grey literature was also identified. A thematic analysis was performed to identify and organise these skills into themes and sub-themes.

RESULTS

195 digital skills were identified, organised in 35 sub-themes and grouped into six main themes: (i) Transversal Digital Skills, (ii) RT Planning Image, (iii) RT Treatment Planning, (iv) RT Treatment Administration, (v) Quality, Safety and Risk Management, and (vi) Management, Education and Research.

CONCLUSION

This list can be used as a reference to close current gaps in knowledge or skills of TR/RTTs while anticipating future needs regarding the rapid development of new technologies (such as Artificial Intelligence or Big Data).

IMPLICATIONS FOR PRACTICE

It is imperative to align education with current and future RT practice to ensure that all RT patients receive the best care. Filling the gaps in TR/RTTs skill sets will improve current practice and provide TR/RTTs with the support needed to develop more advanced skills.

P-064 Clinical outcomes of 127 patients with recurrent implantation failure treated with testicular sperm aspiration (TESA)

Study question

Are the embryological, clinical and newborn outcomes using aspirated testicular sperm improved in cases with recurrent implantation failure previously treated with ejaculated sperm?

Summary answer

Aspirated testicular sperm enabled to obtain significant higher embryological, clinical and newborn outcomes in cases with recurrent implantation failure previously treated with ejaculated sperm.

What is known already

High levels of sperm DNA fragmentation (SDF) were associated to poor clinical outcomes (1-Simon et al., 2017). Testicular sperm display lower SDF than ejaculated sperm (2-Sakas and Alvarez, 2010), improving clinical outcomes in cases with abnormal semen parameters (3-Awaga et al., 2018; 4-Kang et al., 2018), recurrent implantation failure (RIF) and pregnancy loss (RPL) (5-Esteves et al., 2017), and elevated SDF (6-Ambar et al., 2021). As only a few studies are specifically dedicated to RIF, we expanded the number of cases and first provided full demographic, stimulation, embryological, clinical and newborn outcomes.

Study design, size, duration

We retrospectively evaluated during consecutive years (2010-2020) 63 patients with recurrent implantation failure, which accepted to perform testicular sperm aspiration (TESA) as an alternative treatment. These patients presented a long history of failed treatments (153 cycles) using ejaculated sperm. From these cycles, no pregnancy ensued. The present study compares 127 treatment cycles, 80 with testicular sperm (17 cases repeated TESA) and 47 with ejaculated sperm from the same patients performed at the present IVF clinic.

Participants/materials, setting, methods

Patients were screened for karyotype abnormalities, for Y-chromosome microdeletions (7-Gonçalves et al., 2016), and for SDF with the TUNEL assay (8-Sá et al., 2015). Conventional semen analysis was performed according to World Health Organization guidelines (9-WHO, 2010). Male evaluation and TESA was performed by the same experienced urologist (LF) according to established protocols (10-Madureira et al 2014). The procedure was performed entirely on an outpatient basis, with no complications reported.

Main results and the role of chance

The mean ages were 35.5±3.4 (26-42)-female and 38.1±5.7 (29-59)-male. There were 4 abnormal karyotypes (3-female, 1-male), all without known relevance. Most cases had asthenozoospermia and teratozoospermia (65.1%), or oligoasthenoteratozoospermia (41.8%). Of the 19 cases with &lt;5M/ml, none presented Y-chromosome microdeletions. Although we do not routinely perform SDF testing, 15 patients had previous SDF values (12, &gt;20%; 8, &gt;36%). Female basal characteristics and testicular evaluation were under normal values. The TESA procedure took about 15-20 min, and the time of laboratorial search around 30-60 min. Cases using testicular sperm showed significant higher rates of fertilization (64% vs 73%-p=0.005), blastocyst development (47% vs 62%-p=0.010), implantation (6% vs 27%-p=0.000), clinical pregnancy (10% vs 39%-p=0.001), live birth delivery (5% vs 28%-p=0.005) and newborn (5% vs 32%-p=0.000) than ejaculated sperm. No significant differences were observed regarding the rates of embryo cleavage (95% vs 94.8%) and high quality embryos (89.4% vs 94%), in the mean number of transferred embryos (1.8±0.4 vs 1.9±0.4), or in the abortion rate (2 cases-50% vs 7 cases-25.9%). Cases using testicular sperm had 22 frozen-thawed embryo transfer cycles, enabling per initiated cycle a cumulative pregnancy rate of 45%, live birth delivery rate of 31.3% and newborn rate of 37.5% (32 newborn).

Limitations, reasons for caution

Although presenting the higher number of cycles using TESA in the treatment of RIF, this number needs to be increased for drawing more definitive conclusions, as these women present a diversity of conditions, rendering subgrouping difficult. In the future, it would also be important to evaluate SDF in all cases.

Wider implications of the findings

In conclusion, the present results gave further evidence for the superiority of using testicular sperm instead of ejaculated sperm in cases with recurrent implantation failure. Data also evidences the security of using testicular sperm aspiration, as there were no pregnancy or delivery complications, or congenital anomalies among the 32 newborn.

Non-ischemic cardiomyopathy: what predicts survival and ICD shocks after ventricular tachycardia ablation?

Funding Acknowledgements

Type of funding sources: None.

Introduction

Patients (pts) with non-ischemic cardiomyopathy (NICM) present an increased morbidity and mortality from sustained monomorphic ventricular tachycardia (VT). Implantable cardiac defibrillators effectively terminate VT, but ablation is usually required to prevent recurrences and appropriate shocks. Although several risk factors have been pointed out, clear prognostic predictors need to be established and addressed.

Purpose

To evaluate risk factors associated with all-cause mortality and ICD shocks in NICM pts submitted to VT ablation.

Methods

Prospective, observational, single-centre study of pts with NICM submitted to VT ablation using high density mapping tools.The primary outcome was all-cause death or VT recurrence terminated with appropriate ICD shock during long-term follow up. Kaplan-Meier analysis was used to estimate the long-term event-free survival. Uni and multivariate Cox regression analyses were used to determine relevant prognostic predictors.

Results

A total of 27 consecutive pts with NICM were referred for a first-ever VT ablation procedure between June 2015 and June 2021 (males: 93%; mean age: 61±12 years). The mean left ventricular ejection fraction (LVEF) was 35±12% and 70% of pts had NYHA class I or II.

During a mean follow-up of 29 ± 19 months, VT recurrences requiring ICD shocks occurred in 25.9% of pts. VT ablation success and the risk of ICD shocks were not associated with any of the clinical characteristics. Long-term all-cause mortality was 37%. In univariate analysis, LVEF &lt;30%, NT-proBNP, NYHA classification III-IV, chronic kidney disease (CKD), ICD for secondary prevention and prior VT ablation (p=0.08) were associated with reduced survival. On multivariate analysis, CKD was identified as the strongest independent survival predictor (HR 6.9; CI95%: 1.5-23-2, p=0.010)

Conclusions

In pts with NIDM, VT ablation may be successful even in pts with advanced heart disease. However, long-term survival will depend mostly on the stage of disease progression and is strongly associated with the clinical markers of end-stage heart failure. Therefore, a timely referral is crucial to derive the best clinical benefit from VT ablation in this population.

Upgrade pacemaker to CRT: predictors and the importance of LVEF

Funding Acknowledgements

Type of funding sources: None.

Introduction

Nowadays 10-15% of CRT implantaon is upgrading from paents (pts) with pacemaker (PMK) who develop reduced LVEF and worsening symptoms from HF. There are few retrospecve studies showing some predictors of pts with single or dual chamber PMK that may need upgrade to CRT, but it is not completely established which pts may benefit the most.

Purpose

To identify predictors at follow-up of upgrading pacemaker to CRT in a population with pacemaker implantation.

Methods

Single center case-control study of pts that performed upgrading to CRT-pacemaker (CRT-P) in our hospital. We excluded pts that performed upgrade to CRT-D. We compare to a PMK populaon matched to age at implantaon and cause of PMK implantaon. Demographic, clinic and electrocardiographic (ECG) data were considered at baseline. Echocardiographic evaluation was performed before pacemaker/CRT upgrading implantaon and at follow-up. Predictors of upgrading were evaluated by the Cox regression. Prognosc impact of LVEF was evaluated as upgrading to CRT-P by Kaplan-Meier curves.

Results

We included 71 pts that performed CRT-P upgrade (mean age 77±10; 49,6% male, mean LVEF before PMK 54.9±9.2%) and 71 pts with pacemaker implantaon (mean age 78 ± 11; 50,4% male; mean LVEF 60.9±7.2%). The clinical characteriscs, ECG and echocardiographic were similar between pacemaker and CRT-P-upgrade, except atrial fibrillaon being more prevalent in PMK group (57.5% vs 42.5% p=0.039). Mortality was not different duringfollow-up between the two groups. In univariate analysis, QRS duraon (PMK: 115ms vs upgrade CRT-P: 132 ms, p=0.038), LVEF (PMK: 60.9% vs upgrade CRT-P: 54.9%, p=0.002) and LV end-diastolic diameter (LVEDD) (PMK: 48.9.4 ± 6.6mm vs upgrade CRT-P: 56.4 ± 6.6mm, p=0.001), LV end-sistolic diameter (LVESD) (PMK: 29.5 ± 6.5mm vs upgrade CRT-P: 37.9 ± 9 mm, p=0.006) were associate to upgrading to CRT. In our population, the unique independent predictor was lower LVEF(Long Rank 6.108, p=0.013) – Figure 1. The best LVEF cut- off to predict upgradingto CRT was 55% (AUC 0.954, sensitivity 64%, specificity 84%) – Figure 2.

Conclusion

In our populaon of CRT upgrading pts, a broad QRS duraon, lower LVEF and a higher LVEDD and LVESD were associated to upgrade to CTR-P. We try to establish a new value for LVEF that could lead to upgradingto CRT-P, and maybe the classical cut-off of 50% should be reviewed.

Advanced practice roles of therapeutic radiographers/radiation therapists: A systematic literature review

INTRODUCTION

Advances in Radiotherapy (RT) technology and increase of complexity in cancer care have enabled the implementation of new treatment techniques. Subsequently, a greater level of autonomy, responsibility, and accountability in the practice of Therapeutic Radiographers/Radiation Therapists (TR/RTTs) has led to Advanced Practice (AP) roles. The published evidence of this role is scattered with confusing terminology and divergence regarding the perception of whether a specific role represents AP internationally. This study aims to establish an international baseline of evidence on AP roles in RT to identify roles and activities performed by TR/RTTs at advanced level practice and to summarise the impact.

METHODS

A systematic PRISMA review of the literature was undertaken. Thematic analysis was used to synthesise the roles and associated activities. Six RT external experts validated the list. The impact was scrutinised in terms of clinical, organisational, and professional outcomes.

RESULTS

Studies (n = 87) were included and categorised into four groups. AP roles were listed by clinical area, site-specific, and scope of practice, and advanced activities were organised into seven dimensions and 27 sub-dimensions. Three most-reported outcomes were: enhanced service capacity, higher patient satisfaction, and safety maintenance.

CONCLUSION

Evidence-based AP amongst TR/RTTs show how AP roles were conceptualised, implemented, and evaluated. Congruence studies have shown that TR/RTTs are at par with the gold-standard across the various AP roles.

IMPLICATIONS FOR PRACTICE

This is the first systematic literature review synthetisising AP roles and activities of TR/RTTs. This study also identified the main areas of AP that can be used to develop professional frameworks and education guiding policy by professional bodies, educators and other stakeholders.

Anesthetic management of a patient with acquired angioedema submitted to broncofibroscopy: a case report

Acquired angioedema with C1 inhibitor deficiency (AAE-C1INH) is a very rare condition of bradykinin-mediated angioedema. One of its major complications is potentially life-threatening, laryngeal edema. We report a 53-year-old woman with AAE-C1INH proposed for an elective broncofibroscopy. The direct stimulation caused by broncofibroscopy poses a high risk of angioedema, thus presenting an anesthetic challenge. Due to the risk of death, it is essential to adopt preventive measures. Short-term prophylaxis was performed, and the acute treatment was readily available. A well-structured multidisciplinary periprocedural plan makes it possible to safely approach the airway, in a remote area of the hospital.

On- vs off-hours primary percutaneous coronary intervention: a single-centre experience

Introduction

In ST-segment elevation myocardial infarction (STEMI) patients, emergency medical system delays importantly affect outcomes. The effect of admission time in STEMI patients is dubious when percutaneous coronary intervention (PCI) is the preferred reperfusion strategy.

Aims

The authors aimed to retrospectively describe the association between admission time and STEMI patient's care standards and outcomes.

Methods

Characteristics and outcomes of 1222 consecutive STEMI patients treated in a PCI-centre were collected. On-hours were defined as admission on non-national-holidays from Monday to Friday from 8 AM to 6 PM. Time delays, in-hospital and one-year all-cause mortality were assessed.

Results

A total of 439 patients (36%) were admitted on-hours and 783 patients (64%) were admitted off-hours. Baseline characteristics were well-balanced between groups, including the percentage of patients admitted in cardiogenic shock (on-hours: 4.6% vs off-hours 4%; p=0.62).

Median emergency system dependent time to reperfusion (i.e. first-medical contact to reperfusion) did not differ between the two groups (on-hours: 120 min vs. off-hours 123 min, p=0.54). The authors observed no association between admission time and in-hospital mortality (on-hours: 5% vs. off-hours 4.9%, p=0.90) or 1-year mortality (on-hours: 10% vs. off-hours 10%, p=0.97).

In patients admitted directly in the PCI-centre, median time from first-medical contact to reperfusion (on-hours: 87 min vs off-hours: 88 min, p=0.54), in-hospital mortality (on-hours: 4% vs off-hours: 7%, p=0.30) and 1 year mortality (on-hours: 9% vs off-hours: 13%, p=0.27) did not differ between the two groups.

Survival analysis showed no survival benefit of on-hours PCI over off-hours PCI (HR 1.01; 95% CI [0.77–1.46], p=0.95).

Conclusion

In a contemporary well-organized emergency network, STEMI patients admission time in the PCI-centre was not associated with reperfusion delays or increased mortality.

Aortic atherosclerotic plaques: the role of anticoagulation

Introduction

Aortic atherosclerotic plaques (AAPs) are one of the major causes of spontaneous and iatrogenic stroke and peripheral emboli, carrying an high morbidity and mortality. Transoesophageal echocardiography (TOE) plays a key rule on detecting AAP. The therapeutic approach of this patients (pts) is not well stablished.

Purpose

To evaluate the impact of anticoagulation (ACO) therapy on major events in asymptomatic pts with AAP detected in TOE.

Methods

Single-center retrospective study of consecutive patients submitted to TOE between 2010 and 2019 with documentation of AAP. Plaques were described as complex (1) &gt;4mm, (2) ulcerated and (3) mobile thrombi. The plaque location was also documented. We consulted pts data charts for clinical characterization and events recording during the follow up. Major events were defined as stroke, bleeding, hospital admissions (either cardiovascular (CV) and non-CV) and death. Statistical analysis was performed using Cox regression and Chi-square tests.

Results

We enrolled 177 pts with a mean age of 70±10.5 years, 63.8% males, 31.1% diabetic, 73.4% hypertensive, 54.2% with dyslipidaemia, 62.7% obese, 25.4% with peripheral arterial disease, 25.9% with previous stroke and 55.4% with supraventricular arrhythmia. Most of pts had plaques &gt;4mm (80.8%), mobile thrombi in 11.9% and ulcerated plaques in 7.3%; most of the plaques were located in proximal descending aorta (50.3%) and aortic cross (38.4%). Regarding baseline therapy, 52% were under ACO and 50.3% under statin. The main indication of ACO was atrial fibrillation (45.8%).

During follow up (mean time: 1613±1255 days), 61.5% pts died (10.7% from CV causes, 13% with unknown cause), 17.5% had a stroke, 5.7% had other embolic event (lower limbs emboli, unilateral amaurosis and ischemic colitis). Bleeding occurred in 18.3% pts; 47% pts were hospitalized (28.3% from CV cause).

Adjusting for age and comorbidities, there were no significant differences between the group with and without ACO. ACO therapy prevented death from any cause, being also an independent predictor (p=0.08, OR 0.489, IC 95% 0.288–0.831) when adjusted for comorbidities and age. ACO was associated with bleeding events (p=0.003), but not with stroke or hospitalization from any cause (p=NS).

Conclusion

In this subset of pts, ACO therapy prevented death from any cause in pts with AAP. This may have therapeutic implications when approaching this pts, although larger studies to confirm these results are needed.

Managing bifurcations: are two stents better than one?

Introduction

Bifurcation percutaneous coronary intervention (PCI) is associated with a higher degree of complexity when compared with non-bifurcation procedures. Although 1-stent PCI remains the standard approach for most bifurcation lesions, data is constantly being published on 2-stent PCI.

Aim

To evaluate and compare the characteristics and outcomes of patients that underwent bifurcation PCI with one or two stents.

Methods

Single center, retrospective observational study including all patients who underwent bifurcation PCI between January 2015-December 2018. We defined two groups: 1-stent PCI group (1s-PCI) and 2-stent PCI group (2s-PCI). The 2s-PCI group included PCI patients with all the different techniques used in our center: provisional stenting with 2 stents, Cullote, crushing stent and DK Crush.

Results

1s-PCI group included 376 individuals and 2s-PCI group included 26. Overall baseline clinical characteristics were balanced between groups. There was no statistically significant difference in age (mean 64 vs 66; p=0.388), gender (79% vs 85% males; p=0.622) and comorbidities (hypertension, diabetes mellitus, hypercholesterolemia, chronic kidney disease, smoking and previous history of coronary artery disease). Also, there was no difference in clinical status (NSTEMI 36% vs 38%; stable disease 32% vs 42%; STEMI 28% vs 19%; unstable angina 5% vs 0%; p=0.419). Coronary angiography and lesion distribution were similar in both groups (p=0.367). However, radiation dose (median 90.5 [IQR=79] vs 156 [IQR=84] mGy cm2; p&lt;0,001) and contrast volume (median 150 [IQR=100] vs 156 [IQR=83] ml; p&lt;0,001) were significantly higher in 2s-PCI group. At 12-month follow-up, mortality rate was higher in 1s-PCI group, but without statistical significance (8% vs 4%; p=0.71); the same is true for acute myocardial infarction at 12 months (3% vs 0%; p=0.368). Target-lesion failure was only reported in 4 patients in the 1s-PCI group. Survival tests showed no significant difference between groups (χ2(1,n=402)=0.634; p=0.426).

Conclusion

Individuals that underwent 1s-PCI were overall similar to those who underwent 2s-PCI. Predictably, deploying more than 1 stent required more contrast volume and implied a higher radiation dose. We should note that our studied is greatly limited by the 2s-PCI group size, which may justify the lack of difference in the evaluated outcomes.

Pitfalls of cubital electrical nerve stimulation for neuromuscular transmission monitoring: a case report of familial amyloid polyneuropathy

Transthyretin familial amyloid polyneuropathy (FAP) is a rare autosomal dominant disease that provokes systemic deposition of amyloid. It affects the nervous system and it is characterized by progressive sensory, motor, and autonomic neuropathy. Patients with FAP often require surgery and anesthetic care for hepatic transplantation and cardioverter-defibrillator/pacemaker implantation. Peripheric neuropathy is a common finding, but there are no reported cases of its interference with anesthetic neuromuscular transmission monitoring. We report a case of a FAP patient where lack of awareness and distracting factors led to misinterpretation of neuromuscular monitoring and unnecessary sedation and ventilation in the post anesthetic care unit. FAP may interfere with the usual cubital nerve neuromuscular monitoring. Anesthesiologists should be aware of potential neuromuscular compromise to find the best monitoring location for each patient. Sugammadex was safe and reliable in the antagonism of rocuronium neuromuscular blockade in this case, despite the lack of adequate quantitative monitoring.

Temporal characterization of ventricular function and deformation after Takotsubo syndrome using cardiovascular magnetic resonance imaging

Funding Acknowledgements

Type of funding sources: None.

INTRODUCTION

The time course of ventricular recovery in Takotsubo Syndrome (TS) patients(pts) is still not well characterized. Quantification of myocardial deformation using Cardiovascular Magnetic Resonance Feature-Tracking (CMR-FT) may be a useful method to better characterize ventricular recovery during TS.

AIM

To assess the time course of ventricular function using CMR-FT myocardial strain in patients (pts) with an episode of TS.

METHODS

We performed a single-center, retrospective cohort study including 130 pts admitted with TS over a 10-year period. From this cohort, 39 (30%) pts were selected and age and sex-matched with 16 healthy controls for a comparative analysis of myocardial strain using CMR-FT. TS pts were divided in 3 homogeneous subgroups according to the time from index-event and the CMR acquisition: Group 1(G1): &lt;8 days; Group 2(G2): 8 to 30 days; Group 3 (G3): &gt;30 days.

One operator blinded for the study group performed the analysis. Left ventricle (LV) radial strain (RS), longitudinal strain (LS) and right ventricle (RV) LS were quantified.

RESULTS

The mean age of TS group was 66 years and 90% were female. The median ejection fraction (EF) at admission was 38%; 82% displayed an apical ballooning (AB) pattern. Around 19% had at least 1 in-hospital complication and 1.5% died during hospitalization. A significant increase use of CMR was observed over the years (p = 0.001).

Myocardial deformation analysis showed a significant group interaction for LV LS and RS. Specifically, the global values of G1 LV LS and RS were significantly decreased when compared with G3 (LS:-15vs-20%;p = 0.002; RS:40vs61%; p &lt; 0.001) and controls (LS:-15vs-22%;p &lt; 0.001; RS: 40vs70; p &lt; 0.001). There were no significant differences in the RV LS across groups.

The CMR-quantified EF was significantly decreased in G1 when compared with G3 (52vs64%; p &lt; 0.003) and controls (52vs64%; p &lt; 0.001). Differences between G1 and G2 were found in LV RS (LS:40vs57%; p &lt; 0.001) and EF (52vs62%; p &lt; 0.001). No differences were observed for any parameters between G3 and controls.

This study showed that global LV LS (r=-0.6, p &lt; 0.001) and RS (r = 0.7, p &lt; 0.001) had a significant correlation with the CMR-quantified EF.

A comparison between the different patterns of TS was also performed (Figure 1). Pts with AB pattern in G1 displayed lower global RS (P = 0.014), although there were no differences regarding global LS. As expected, in the AB group the reduction in myocardial strain was limited to the apical segments.

Despite not being significantly different across groups RV LS was the only CMR-derived predictor of complications during follow-up (OR = 1.17; p = 0.026).

CONCLUSION

This study revealed that after an episode of TS myocardial function quantified either by EF or CMR-FT strain fully recovers between the 8th and 30th day of the event. RV strain was a predictor of complications during follow-up.

Type of funding sources: None.

INTRODUCTION

Atrial fibrillation (AF) is an adverse prognostic factor during acute coronary syndrome (ACS). Current evidence recommends dual antithrombotic therapy (DAT), 1 antiplatelet drug and 1 anticoagulant drug, as the default strategy after nonST elevation ACS.

AIM

To identify the clinical differences and prognosis of AF type-new onset (nAF) or pre-existing (pFA)- during ACS, to evaluate antithrombotic strategy at hospital discharge (HD) and its impact on haemorrhagic and ischemic events.

METHODS

We performed a retrospective observational cohort study including 3241 patients (pts) with ACS (mean age 64 years, 77.5% male) admitted to a single center over a 6-year period, with 12-months follow-up.

RESULTS

AF rhythm was identified in 11.2% pts, of whom 63.2% presented nAF and 36.8% pAF.

When AF types where compared, pts with pAF had a higher prevalence of cardiovascular (Cv) comorbidities, including hypertension (p &lt; 0.001), previous ACS (p = 0.03), valvular disease (p = 0.01) or stroke (p = 0.05), had greater left atrial diameter (p &lt; 0.001) and were less likely to have significant coronary lesions (p = 0.05). Pts with nAF more frequently presented with STelevation ACS (p &lt; 0.001) and had a lower Hemoglobin nadir (p &lt; 0.001). The independent predictors of nAF in ACS were age (OR 1.1, p&lt; =0.001), LVEF ≤ 40% (OR 2.2, p = 0.001), STelevation ACS (OR 2.6, p&lt; =0.001) and previous valvular disease (OR 3.5, p&lt; =0.01). Compared with the population without AF, nAF was a predictor of in-hospital death (OR 2.9, p = 0.027) and in-hospital composite endpoint (death, stroke, reinfarction and cardiogenic shock) (OR 2.5, p = 0.001) in multivariate analysis, but pAF wasn’t. During 12-months follow-up of pts with ACS and AF, there was no difference regarding death or follow-up composite endpoint (death, stroke and ACS) between the AF types.Regarding antithrombotic therapy, nAF pts were less often anticoagulated (p &lt; 0.001) and pAF pts where more often treated with triple antithrombotic therapy (TAT) at HD (&lt;0.001). Most of the pts with TAT stopped the second antiplatelet at agent 6-months (43.8%) or 12 months (25.5%) after HD. During 12-months follow-up, pts discharged with TAT had trend towards more haemorrhagic events (TAT 6.2% vs DAT2.7%,p = 0.69) and both groups had similar ischaemic events (death, ACS, stroke) (TAT 20.9% vs DAT23.7%,p = 0.714). In multivariate analysis the choice of TAT or DAT wasn’t a predictor of ischaemic events.

CONCLUSIONS

In ACS, pts with nAF had worst in-hospital outcomes than pts with pAF. Regarding antithrombotic strategy at HD pts with nFA were less often anticoagulated and less often treated with TAT. In our study the choice between DAT or TAT had no statistical impact on follow-up outcomes.

Syncope: call for the missed diagnosis

Funding Acknowledgements

Type of funding sources: None.

Background

Syncope is a common reason for emergency department attendance. This entity may be associated with significant morbidity and mortality and its differential diagnosis is not straightforward. Arrhythmic causes include tachycardia and bradycardia; the later may require pacemaker implantation. Many hospitals lack a dedicated syncope unit to approach these patients. So, patients’ triage may fall into medical or surgical (trauma) areas.

Purpose

To describe the population of patients that required permanent pacemaker implantation in the year of 2019, particularly those who had a previous visit to the emergency department with syncope or presyncope.

Methods

Single-center descriptive analysis of patients that implanted a permanent pacemaker in 2019 (inclusion criteria). Additional information was collected in patients with emergency department visits in the 365 days that preceded the device implantation.

Results

In 2019, a total of 398 patients were admitted for pacemaker implantation in 2019, 55% male (n = 218), 45% female (n = 180), with mean age of 79 years. Regarding indications for pacing, 41% (n= 156) had complete atrioventricular (AV) block, 26% (n = 105) had a second degree AV block, 16% (n = 64) had sinus node dysfunction, 13.5% (n = 53) had atrial fibrillation with slow ventricular conduction, and 3.5% (n = 14) had other indications.

Twenty-two percent (n = 88) of patients had a previous visit to the emergency department (other than the ones that triggered the pacemaker implantation) with complaints of syncope (60%) or presyncope (40%). Of these, 73% (n = 64) were referred to a medical area and 27% (n = 24) were referred to a surgical area; 40 patients presented with traumatic lesions (68% cranioencephalic trauma and 32% other traumas). Of the 88 patients, only 67% (n = 59) performed an ECG and only 23% (n = 20) were referred for observation by a cardiologist in the emergency department.

Comparing medical and surgical triage, we observe that patients referred to the surgical area were less likely to perform an ECG and to be observed by a cardiologist (with statistical significance).

Conclusions

Our work describes a common problem in hospitals without dedicated syncope evaluation units. As all the patients ended up implanting a pacemaker, it is interesting to observe that 22%of these had a "warning" visit to the emergency and 33% of the last did not get and ECG. Also, trauma-oriented approaches result in a lower likelihood of performing a complete evaluation of the cause of the syncopal event. This analysis highlights the need for a comprehensive and multidisciplinary approach of patients presenting with syncope and presyncope to promote early identification and treatment of arrhythmic causes, reducing patient morbidity and healthcare costs.

Dermatitis artefacta and psychiatric illness: Brief review and case report

Introduction

Psychodermatologic disorders are conditions involving an interaction between the mind and the skin. Dermatitis artefacta (DA), also known as factitial dermatitis, is a frequently unrecognized psychocutaneous illness, in which the patient creates skin lesions to satisfy the unconscious need to presume a sick role. It is more common in women and in patients with a diagnosis of psychiatric illness. This is an exclusion diagnosis and organic causes should be ruled out. Treatment of DA can be challenging and it needs to involve a multidisciplinary approach consisting of dermatologists and mental health professionals.

Objectives

From a case report the authors intend to present a literature review of dermatitis artefacta.

Methods

Observation the patient and review the clinical file. Consultation published and referenced scientific articles on PubMed.

Results

60 year old man, diagnosed with Bipolar Disorder, was admitted for manic decompensation of his pathology. During physical examination he had sparse erythematous lesions, more exuberant in the neck, scalp, belly and upper limbs. The diagnosis of artifact dermatitis was made after excluding other possible causes.

Conclusions

Treatment of DA can be challenging and it needs to involve a multidisciplinary approach. Dermatitis artefacta is a long-term disorder, and patients need regular follow up with a dermatologist and a psychiatrist because relapses are common. These doctors must be aware of this possible pathology in order to make a correct diagnosis and treatment of psychiatric disorders that sometimes coexist with skin lesions. The prognosis for most patients is poor leading to self-injury, scarring and poor cosmesis.

Inaugural seizure in a patient submitted to electroconvulsive therapy and anti-psychotic treatment: Who’s the culprit?

Introduction

Electroconvulsive Therapy (ECT) is one of the most effective treatments for Depressive Disorder. Although its safety and tolerability have been throughout the years, it still holds common mild and rarely persistent side effects.

Objectives

The aim is to review some of the most recent data on the connection between inaugural seizures in psychiatric patients being submitted to ECT for treatment of Major Depressive Disorder, while also discussing the possible contribution of the concomitant use of clozapine and clomipramine.

Methods

The authors present a case report of an episode of an inaugural seizure in a patient submitted to ECT, with concomitant use of clozapine and clomipramine. A search on Pubmed and Clinicalkey was performed, from which the relevant publications were selected and reviewed.

Results

The authors present a 62 year old woman who developed an inaugural generalized tonic-clonic seizure after being submitted to ECT for treatment of Recurrent Major Depressive Disorder (RMDD), while also carrying out clozapine and clomipramine dosage reduction, with the purpose of discontinuation. The patient had no history of previous seizures, nor were there relevant findings in the patient’s neurological examination, blood work, brain CT or EEG.

Conclusions

There is a plethora of possible factors involved in the development of an inaugural seizure. Although, the risk of spontaneous seizure during ECT is low, it may be increased by the concomitant use of drugs which can lower the seizure threshold. In most cases, when ECT was resumed after removal of such triggers, there were no further complications.

The coronavirus pandemic impact on involuntary hospitalization

Introduction

Compulsory admission is the last line of intervention in individuals who suffer from severe mental disorders, based on the principles of therapeutic need and social protection. In Portugal, the law configures this measure as a hospitalization by court order. The SARS-CoV-2 coronavirus is a global public health emergency, with multifaceted consequences for people’s lives and health. Several studies are showing a great impact of the pandemic on the overall mental health.

Objectives

The aim is to assess the impact of the pandemic on the number of involuntary hospitalizations, their socio-demographic and clinical characteristics, and study the differences between 2019 and 2020.

Methods

Consultation of all patient’s clinical files that were involuntarily admitted in Hospital Magalhães Lemos during 2019 and 2020. Statistical analysis of data.

Results

The authors claim to investigate the impact of the pandemic on involuntary hospitalizations, the factors of admission and decompensation and other clinical characteristics, by comparing the involuntary hospitalizations during 2019 and 2020. The authors believe that the number of compulsory admissions increased significantly with the pandemic. They also believe that factors such as increased or relapsed consumption of alcohol and drugs, suicide attempts, missed appointments and long-term injectable medication are at the root of this increase in 2020.

Conclusions

This study helps to analyze the impact of the new coronavirus on compulsory hospitalizations and allows to understand the main factors that aggravate the underlying pathologies. Thus, understanding the targets of greater attention from psychiatrists to avoid the decompensation of patients in times of pandemic in which we currently live.

Use of methylphenidate in alzheimer’s dementia: Effect on apathy

Introduction

Alzheimer’s Disease (AD) is associated with neuropsychiatric symptoms such as agitation depression and apathy. It has been proposed that the pathophysiology of apathy, that is defined as quantitative reduction in goal-directed activity compared with previous functioning, in AD is associated with degeneration of prefrontal cortex and dysfunction of dopamine and norepinephrine neurons in the brain. Methylphenidate (MPH) is a dopamine and norepinephrine reuptake inhibitor and its action increase the availability of these neurotransmitters in the extracellular space of striatum and prefrontal cortex. Over the past decade there has been an effort to study the benefit of the use of MPH for treatment of apathy in patients with Alzheimer’s dementia.

Objectives

Study the benefit of methylphenidate in the treatment of apathy in AD.

Methods

Basic literature review collecting data from PubMed (2010-2020) using the words “Methylphenidate”, “Apathy”, “Alzheimer”, “Dementia”.

Results

Clinical trials using 10 to 20mg of MPH per day, for 6 weeks, demonstrated a mitigation in apathy symptoms in one third of patients, with good tolerability. Another clinical trial using the same dosage, for 12 weeks, led to improvement in cognition, functional status, depression and caregiver burden.

Conclusions

New clinical trials with larger groups of patients over a longer period are needed to consolidate the existing results. Although there are still many questions concerning the usefulness of methylphenidate in this population that need to be answered, methylphenidate might be an option to deal with one of the most prevalent neuropsychiatric symptoms, apathy, in some AD patients.

Filiation delusion: A rare presentation

Introduction

The filliation delusion was first described in 1950 by Ey as a false belief about belonging to a family group other than one’s own. Since then, 70 years have passed and litterature is still scarce on this type of presentation.

Objectives

Using a case report as a starting point, the aim of this article is to review data on the various frameworks of delusional development, while discussing in what capacity social cognition impairment, theory of mind and overall lack of insight, typical in schizophrenic patients, could be related to this type of delusion.

Methods

The authors present a case report of an episode of a filliation delusion in a patient with chronic schizophrenia. A search on PubMed and ClinicalKey was performed, from which the relevant publications were selected and reviewed.

Results

The case referes to a 64 year old woman previously diagnosed with schizophrenia who developed, over the period of two years, a filliation delusion. The patient believed having been born in Russia and being subsequently adopted by different families. There was history of irregular attendance to consultations and non-compliance to treatment.

Conclusions

There is still lack of proper investigation regarding the development of delusions in schizophrenic patients. Social cognition and insight are important predictors of functioning, and might behave as a marker of liability to psychosis. This should have strong implications in these patients’ treatment approaches. The lack of consensual measurement instruments make it difficult to draw solid conclusions, and this should be the main focus moving forward.

Psychiatric disorders during acute hospital treatment of COVID-19 - a case series

Introduction

Coronavirus disease (COVID-19) has been associated with the development mental and behavioural symptoms and psychiatric disorders. This association is stronger in severe cases of the disease and in those needing inpatient treatment, particularly in intensive care units (ICU).

Objectives

To determine the incidence of psychiatric disorders in a Portuguese hospital-based sample of patients with COVID-19. To describe relevant demographic and clinical data.

Methods

We reviewed all COVID-19 inpatients assessed by liaison psychiatry at our hospital between April and September 2020. Patients admitted due to a psychiatric disorder were excluded from the analysis. We reviewed medical records and retrieved relevant clinical data. ICD-10 was used to classify diagnoses.

Results

We identified 36 cases with a mean age of 62.64 years-old (SD 19.23). The most common disorder was delirium, which occurred in 41.7% of our sample (15 patients), followed by adjustment disorder (22.2%, n=8), and depressive episode (16.7%, n=8). Most patients had no personal (61.1%, n=22) nor family (75%, n=27) history of a psychiatric disorder. Mean length of admission was 36.89 days (SD 28.91). Seventeen cases (47.22%) had at least one risk factor for severe COVID-19 disease and 14 (38.89%) were admitted at some point to the ICU.

Conclusions

In our sample, delirium was the main cause for mental or behavioural symptoms in COVID-19 patients. However, we observed a wide array of presentations in our center. A larger sample would allow to better characterize this often-overlooked symptoms and identify risk factors to psychiatric syndromes.
