Beyond pulmonary rehabilitation: can the PICk UP programme fill the gap? A randomised trial in COPD

INTRODUCTION AND OBJECTIVES

Pulmonary rehabilitation (PR) is a fundamental intervention to manage COPD, however, maintaining its benefits is challenging. Engaging in physical activity might help to prolong PR benefits. This study assessed the efficacy and effectiveness of a personalised community-based physical activity programme to sustain physical activity and other health-related PR benefits, in people with COPD.

MATERIALS AND METHODS

This was a multicentre, assessor blinded, randomised controlled trial. Following 12-weeks of PR, people with COPD were assigned to a six-months personalised community-based physical activity programme (experimental group), or to standard care (control group). Physical activity was assessed via: time spent in moderate to vigorous physical activities per day (primary outcome measure), steps/day and the brief physical activity assessment tool. Secondary outcomes included sedentary behaviour, functional status, peripheral muscle strength, balance, symptoms, emotional state, health-related quality of life, exacerbations and healthcare utilization. Assessments were performed immediately post-PR and after three- and six-months. Efficacy and effectiveness were evaluated using intention-to-treat and per-protocol analysis with linear mixed models.

RESULTS

Sixty-one participants (experimental group: n = 32; control group: n = 29), with balanced baseline characteristics between groups (69.6 ± 8.5 years old, 84 % male, FEV1 57.1 ± 16.7 %predicted) were included. Changes in all physical activity outcomes and in one-minute sit-to-stand were significantly different (P < 0.05) between groups at the six-month follow-up. In the remaining outcomes there were no differences between groups.

CONCLUSIONS

The community-based physical activity programme resulted in better physical activity levels and sit-to-stand performance, six-months after completing PR, in COPD. No additional benefits were observed for other secondary outcomes.

Unsupervised physical activity interventions for people with COPD: A systematic review and meta-analysis

INTRODUCTION AND OBJECTIVES

Unsupervised PA interventions might have a role in the management of chronic obstructive pulmonary disease (COPD) but their effectiveness is largely unknown. Thus, we aimed to identify and synthesise data on the effects of unsupervised PA interventions in people with COPD.

MATERIAL AND METHODS

Databases were systematically searched in April 2020, with weekly updates until September 2021. Randomised controlled trials and quasi-experimental studies comparing unsupervised PA with usual care, were included. Primary outcomes were dyspnoea, exercise capacity and physical activity. The effect direction plot was performed to synthesise results. Meta-analysis with forest plots were conducted for the Chronic Respiratory Disease questionnaire - dyspnoea domain (CRQ-D), 6-minute walk distance (6MWD) and incremental shuttle walk distance (ISWD).

RESULTS

Eleven studies with 900 participants with COPD (68±10 years; 58.8% male, FEV1 63.7±15.8% predicted) were included. All interventions were conducted at home, most with daily sessions, for 8-12 weeks. Walking was the most common component. The effect direction plot showed that unsupervised PA interventions improved emotional function, fatigue, health-related quality of life, muscle strength and symptoms of anxiety and depression. Meta-analysis showed statistical, but not clinical, significant improvements in dyspnoea (CRQ-D, MD=0.12, 95% CI 0.09-0.15) and exercise capacity, measured with 6MWD (MD=13.70, 95% CI 3.58-23.83). Statistical and clinical significant improvements were observed in exercise capacity, measured with ISWD (MD=58.59, 95% CI 5.79-111.39). None to minor adverse events and a high adherence rate were found.

CONCLUSIONS

Unsupervised PA interventions benefits dyspnoea and exercise capacity of people with COPD, are safe and present a high adherence rate. Unsupervised PA interventions should be considered for people with COPD who cannot or do not want to engage in supervised PA interventions or as a maintenance strategy of PA levels.

French validation of the Quality of life in Essential Tremor Questionnaire (QUEST) and the Essential Tremor Embarrassment Assessment (ETEA)

Two scales have been developed and validated in English to evaluate the impact of tremor on daily life, namely Quality of life in Essential Tremor Questionnaire (QUEST) and Essential Tremor Embarrassment Assessment (ETEA). The psychometric properties of the French version of these two scales were assessed for 117 patients with head tremor. Both scales showed excellent acceptability, very good internal consistency (Cronbach's alpha coefficient>0.8) and reproducibility (Lin concordance coefficient>0.8), satisfactory external validity and satisfactory sensitivity to change. In conclusion, the French versions of QUEST and ETEA are comprehensive, valid and reliable instruments for assessing patients with head tremor.

Pooling Saliva Sample as an Effective Strategy for the Systematic CMV Screening of Newborns-A Multicentric Prospective Study

BACKGROUND

Cytomegalovirus is the most common cause of congenital infections worldwide. Screening all newborns in the first 2 weeks of life is the only way to detect all cases of congenital infection, allowing the monitoring of children with asymptomatic infection at birth and early intervention.

AIM

In this multicenter study, we aimed to evaluate the feasibility of using a saliva pool strategy for mass screening in 7 Portuguese hospitals, and to estimate the current prevalence of this congenital infection in these hospitals.

METHODS

A total of 7033 newborns were screened between June 2020 and June 2022, and 704 pools of 10 saliva samples were analyzed by polymerase chain reaction (PCR).

RESULTS

Of the 704 pools analyzed, 685 were negative and 19 had positive PCR results for cytomegalovirus. After individual PCR testing, 26 newborns had positive saliva results, of which 15 were confirmed by urine testing. Thus, this study's prevalence of congenital infection was 0.21% (95% confidence interval: 0.12%-0.35%).

CONCLUSIONS

In this study, the pooling strategy proved to be effective for the systematic screening of newborns, although this low prevalence raises questions regarding the cost-effectiveness of implementing universal screening. However, this prevalence is probably the result of the control measures taken during the pandemic; therefore, the rates are expected to return to prepandemic values, but only a new study after the pandemic will be able to confirm this.

Impact of acute exacerbations of COPD on patients' health status beyond pulmonary function: A scoping review

This scoping review summarized the evidence regarding the impact of acute exacerbations of COPD (AECOPD) on patients' health status beyond pulmonary function. PubMed, Embase, and Web of Science were searched. Prospective cohort studies assessing the health status of patients with COPD in a stable phase of the disease and after a follow-up period (where at least one AECOPD occurred) were included. An integrated assessment framework of health status (i.e., physiological functioning, complaints, functional impairment, quality of life) was used. Twenty-two studies were included. AECOPD acutely affected exercise tolerance, quadriceps muscle strength, physical activity levels, symptoms of dyspnoea and fatigue, and impact of the disease. Long-term effects on quadriceps muscle strength, symptoms of dyspnoea and depression, and quality of life were found. Repeated exacerbations negatively impacted the fat-free mass, levels of dyspnoea, impact of the disease and quality of life. Conflicting evidence was found regarding the impact of repeated exacerbations on exercise tolerance and physical activity levels. AECOPD have well-established acute and long-term adverse effects on health status beyond pulmonary function; nevertheless, the recovery trajectory and the impact of repeated exacerbations are still poorly studied. Further prospective research is recommended to draw firm conclusions on these aspects.

Reliability and validity of the Chester step test in patients with interstitial lung disease

BACKGROUND

The Chester Step Test (CST) is a simple and inexpensive field test, which requires minimal physical space to assess exercise capacity. Such characteristics make the CST suitable to be used in different settings, however, its measurement properties in patients with interstitial lung diseases (ILD) are unknown.

METHODS

A cross-sectional study was conducted in patients with ILD. First, a CST-1 and a 6-minute walk test (6MWT) were performed. After 48-72 hours, a CST-2 was repeated. A 2nd rater was present in one of the sessions. Relative reliability was measured using intraclass correlation coefficient (ICC1,1 and ICC2,1). Absolute reliability was determined using standard error of measurement (SEM), minimal detectable change at 95% confidence interval (MDC95) and the Bland-Altman method. The values of SEM and MDC95 were also expressed as a percentage of the mean. Construct validity was explored using Spearman correlation coefficient (rs) between the number of steps taken in the best CST and the distance performed in the 6MWT.

RESULTS

Sixty-six patients with ILD (65.5±12.9 years; 48.5%men; FVC 79.4±18.8pp; DLCO 49.0±18.3pp) participated in the study. Relative (ICC 0.95-1.0) and absolute reliability were excellent without evidence of systematic bias. The SEM and MDC95 were 11.8 (14.7%) and 32.6 steps (40.7%), respectively. The correlation between CST and 6MWT was significant, positive, and high (rs=0.85, p=0.001).

CONCLUSION

The CST is a reliable and valid test and might be especially useful to assess exercise capacity in patients with ILD in limited space environments.

Percutaneous coronary intervention in elderly patients with chronic kidney disease and non-ST segment elevation acute coronary syndrome – is it worth it?

 

ESC guidelines recommend revascularization in patients (pts) with chronic kidney disease (CKD) irrespective of age. However, elderly pts are usually underrepresented in the available data on percutaneous coronary intervention (PCI). Thus, the decision on whether to perform PCI in these pts is usually at the discretion of the cardiology team.

Aim

To evaluate the impact of PCI vs conservative approach (CA) in elderly pts (&gt;80 years) with CKD and unstable angina (UA)/non-ST segment elevation myocardial infarction (NSTEMI) who were enrolled in the Portuguese National Registry of Acute Coronary Syndromes. To determine impact of CKD in in-hospital (IH) and long-term outcomes, including MACE (myocardial infarction, stroke and death) and death at 1 year.

Study population

Elderly pts admitted with UA and NSTEMI, from 2010 until 2021. There were three different groups: Group 1 – eGFR ≥60 ml/min/1.73 m2; Group 2 – eGFR between 30 and 59 ml/min/1.73 m2 and Group 3 – eGFR &lt;30 ml/min/1.73 m2. Pts with ST-segment elevation myocardial infarction and cardiogenic shock were excluded.

Results

A total of 2443 pts, of which 921 (37,7%) were submitted to PCI. 50,2% (n=1126,) were from the group 1, 38,5% (n=941) from group 2 and 11.3% (n=276) from group 3.

Regarding overall population, pts submitted to PCI were mainly male (60,4%) with a mean age of 84±3 years old. They had previous history of PCI (21,6% vs 15,1% p&lt;0.001), less history of heart failure (HF), stroke or dementia (8,5% vs 16,5%; 8,1 vs 13.3% and 2,1 vs 5,9%, p&lt;0.001). At presentation they had more angina (88,8% vs 81,2% p&lt;0.001), less NT-proBNP levels (387 vs 561 p&lt;0.001) and were more frequently in KK class I (75,6% vs 70,2% p=0.004). They developed less HF (21% vs 27%, p&lt;0.001) and MACE (5,7% vs 9,1% p=0.003). Pts in the group 3 were less submitted to PCI (27,5% vs 38,2% vs 39,6% p&lt;0.001) and had more MACE and cardiovascular death when comparing to group 2 and 1 (16,1% vs 8,7% vs 5,3% and 10,5% vs 5,5% vs 2,6% p&lt;0.001 respectively).

Comparing PCI vs CA in each group, there was no difference in IH outcomes between both strategies in group 3. The same was not true for groups 1 and 2, in which PCI seemed to favor overall outcomes (p=0.001 and p=0.015 respectively).

The predictors of IH death and MACE were: age (OR 1.068 p=0.010), dementia (OR 2,376 p=0.015), KK class &gt;1 (OR 2,243, p&lt;0.001), atrial fibrilhation (OR 1.605, p=0.046), not having PCI (OR 0.309, p&lt;0.001), eGFR &lt;30 (OR 3.51, p&lt;0.001) and PCI in pts with eGFR &lt;30 (OR 2.923, p=0.019).

Interestingly, survival analysis showed that pts submitted to PCI in all 3 groups (including group 3) had a longer 1-year survival (p&lt;0.001, p&lt;0.001 and p&lt;0.004).

Conclusions

PCI performance in elderly pts with CKD should be individualized. In our population, especially in group 3, the performance of PCI is associated with a higher IH mortality, however, after surviving hospitalization, these pts seem to have a benefit in 1 year survival.

Should we stay or should we go: assessment of the need for the implantation of a definite pacemaker in a population of acute coronary syndrome that evolved in advanced atrioventricular block

Introduction

The incidence of advanced atrioventricular block (AVB) secondary to acute coronary syndrome (ACS) has been decreasing in the era of percutaneous revascularization and in most cases is transitory and does not require pacemaker (PM) implantation.

Purpose

Our aim was to assess the characteristics of patients with AVB as a consequence of the ACS and compare those with and without PM implantation, in what regards in-hospital and at 1 year outcomes.

Methods

We performed a retrospective analysis of all patients admitted with AVB secondary to ACS in Portugal between October of 2010 and August of 2021 with data from the Real World Portuguese Registry on Acute Coronary Syndromes (ProACS). Medical records were analysed for demographic, procedural data and outcomes.

Results

Sex hundred and seventy one (671) patients with AVB secondary to ACS were admitted, which corresponded to 2.2% of the total cohort. The mean age was 70±13 with a male preponderance (66%). The ACS was categorized as ST elevation Myocardial Infarction (STEMI) in 76.4%, non-STEMI (NSTEMI) in 22.1%, and unstable angina (UA) in 1.5%. Of the patients admitted with AVB, 8.6% implanted a permanent PM. The was no clinically relevant differences in both groups in what regards to medical priors or medication. Regarding the location of the infarction, an Anterior STEMI was the diagnosis of admission in 36.8% (vs 14.5%; OR 3.45, CI 95% 1.31–9.06, p&lt;0.05) of patients that implanted a PM, and the left descending artery was more frequently the culprit artery, and an Inferior STEMI was the diagnosis of 63.2% (vs 83.7%; OR 0.31, CI 95% 0.12–0.82, p&lt;0.05) of patients and a right coronary artery was more frequently the culprit artery.

The presence of cardiovascular shock and in-hospital death was significantly more frequent in the group that did not implant a PM (OR 0.40; CI 95% 0.17–0.95, p&lt;0.05 and OR 0.33; CI 0.12–0.92, p&lt;0.05 respectively) and the implantation of PM was a negative predictor of in-hospital death (OR 0.28; CI 95% 0.08–0.93, p&lt;0.05).

The follow up at 1 year was performed in two hundred and sixty three (263) patients, 10.6% with an implanted PM. The survival analysis demonstrated increased mortality and a combined end-point of death and readmissions in the population of AVB that did not implant PM compared with a population who did not present with AVB (p&lt;0.05) with the Kaplan Meier curves widening significantly (Figure 1). This difference was not observed compared with an AVB population that implanted PM.

Conclusions

In patients with AVB secondary to ACS, the implantation of a PM might have been withheld in more severe patients, accounting for the increased mortality observed, and this population has worse outcomes at 1 year, leaving open to the hypothesis if either due to a more severe clinical status or the recurrence of AVB.

A First Record of Organochlorine Pesticides in Barn Owls (Tyto alba) from Portugal: Assessing Trends from Variation in Feather and Liver Concentrations

We evaluated feathers as a non-destructive biomonitoring tool documenting organochlorine pesticides (OCP) in liver and checked possible trends in pesticide use in two areas based on OCP concentrations in barn owls (Tyto alba). We measured the concentrations of 16 OCP in 15 primary feathers and 15 livers from barn owl carcasses collected on roadsides in Tagus Valley and Évora regions, south Portugal. Total OCP mean concentration was 8 120 ng g^-1 in feathers and 178 ng g^-1 in livers. All compounds were detected in feathers while in livers δ-HCH, endosulfan sulphate, p,p'-DDT and p,p'-DDD were not detected. The high β-HCH and heptachlor concentrations in feathers most likely derived from external endogenous contamination. P,p'-DDE was the OCP with the highest hepatic concentration. Both matrices indicated an exposure to recently released heptachlor. The differing OCP concentrations between Tagus Valley and Évora seem to reflect differences in land-use and pesticide use histories of the two locations, and/or faster degradation of OCP in the Tagus area.

Catatonia and dementia: a case report

Introduction

Catatonia is a neuropsychiatric disorder characterized by motor, behavioral and autonomic changes. It is associated with several psychiatric disorders, including dementia. Catatonia is an underdiagnosed syndrome, so it is important to draw attention to it. Here, we review a case of a patient admitted to our psychiatric department with a clinical presentation compatible with catatonia. After proper treatment, further assessment revealed dementia.

Objectives

This work aims to describe a case of catatonia in a patient with dementia.

Methods

Bibliographic research using Pubmed®. Clinical file consultation and patient interviews.

Results

Catatonia is a disorder that was already been described as part of several types of dementia. We present a 69-year-old female patient, admitted to our psychiatric department with clinical presentation compatible with catatonia. To admission, she presented some typical complications resulting from long immobility such as pressure ulcers and nutritional deficiencies. During the hospitalization, she developed a urinary infection and there was the need to tube feeding. She was treated with benzodiazepines and improved. Further assessment revealed dementia.

Conclusions

Catatonia in dementia is not uncommon, although it is an underdiagnosed syndrome, and when treated early and properly it has a good prognosis.

Role of migration in the development of a first episode of psychosis

Introduction

Currently, there is scientific evidence supporting the relationship between socio-environmental factors and the onset of a first episode of psychosis (FEP). In this context, the phenomenon of migration, seen as a negative life experience, may become an important risk factor in developing a psychotic disorder (PD). In Europe, the impact of this phenomenon is growing and, therefore, it’s necessary to provide a proper answer to these individual’s mental health problems.

Objectives

Identify which phases of this migration process are most important in the development of a FEP and what are the more significant socio-environmental factors in each phase.

Methods

Bibliographic research in Pubmed database using the terms “Migration” and “First Episode Psychosis”.

Results

Research confirms that migrants have a 2 to 3-fold increased risk of developing a PD. This risk will be even higher in the refugee population. Pre- and post-migration factors demonstrated to be more important than factors related with the migration process itself. In the pre-migration phase highlight factors like the lower parental social class and a previous trauma. In the post-migration phase highlight factors like discrimination, social disadvantage and a mismatch between expectations and reality.

Conclusions

Literature is unanimous in considering migrant status as an independent risk factor for the development of FEP, possibly due to the outsider’s role in society. Thus, despite the growing interest in Biological Psychiatry, this work demonstrates that socio-environmental factors are very preponderant in the development of these disorders and because of that further investigation is still necessary.

“Walking with myself by my side” - non-medical use of Ketamine

Introduction

Ketamine, synthesized in 1962 as phencyclidine derivate, is denominated a “dissociative anesthetic” because of its side-effects, such as dissociative episodes and psychotic-like symptoms, which have limited its applicability on clinical practice. Otherwise, in the last decades the non-medical use of ketamine has been growing and today is one of the most popular illicit substances consumed between adolescents and young adults.

Objectives

Increasing the knowledge and understanding of the factors related to crescent use of ketamine and the experiences and consequences associated to its consumption.

Methods

Clinical interview with patients diagnosed with ketamine use disorder and bibliographic research in Pubmed database using the terms “Ketamine use” and “Ketamine addiction”.

Results

Pat et al. (2002) describes a clinical case of a young male, diagnosed with substance use disorders, specifically alcohol and cocaine use disorders, that started a treatment with ketamine. After the treatment, pleasant depersonalization experiences contributed to the development of patient’s ketamine dependence. Other patient’s reports confirm the association of ketamine use with psychedelic effects and dissociative episodes and pointed these effects as main reason for its consumption.

Conclusions

The adverse effects that limited the medical use of ketamine are the same that promote its utilization with recreational purposes by adolescents and young adults in parties and nightclubs. About the ketamine dependence, the literature is scarce and doesn´t clearly identify a physical withdrawal syndrome, pointing only to a serious psychological dependence. Thus, with the crescent non-medical use of ketamine, it’s urgent to develop an intervention plan directed to this problem.

AB1565-HPR REHABILITATION NURSES KNOWLEDGE ABOUT OSTEOPOROSIS AND FRAGILITY FRACTURES IN PORTUGAL

Background

Scientific evidence reveals gaps in health professionals’ knowledge about osteoporosis and fragility fractures, which impairs and influences the quality of care, namely in preventive actions.

Objectives

To analyse knowledge of Rehabilitation Nurses about osteoporosis and fragility fractures to identify training needs of Rehabilitation Nurses.

Methods

A cross-sectional study, integrated in a larger project, using an adapted questionnaire, made available online and disseminated by mailing list of “Ordem dos Enfermeiros” (Royal Colleague of Nursings) to all Portuguese Rehabilitation Nurses.

Results

There were include 452 participants(10.3% of the 4 397 Rehabilitation Nurses), 17% perform functions in orthopaedics and traumatology service, 4.5% physical medicine and rehabilitation and 78.6% in other services, majority, 74.6% women. On average, 69.6% correct answers were identified regarding osteoporosis and fragility fractures. Results reveal that the main areas of knowledge deficit, in this study, are related to the concept and epidemiology of osteoporosis and fragility fractures and about the most appropriate diet. Nurses with higher academic degree (master’s degree) revealed more knowledge (p=0.01).

Conclusion

This study reveals that the knowledge about osteoporosis and fragility fractures is low (<70% correct answers), thus there is an opportunity to improve the knowledge related to osteoporosis and fragility fractures among Specialist Nurses in Rehabilitation Nursing.

Dissociation and emotional dysregulation in pathological personalities related to the fear of SARS-COV-2: a case report

Introduction

The COVID-19 pandemic represented a serious strain on the mental health resilience worldwide. Implementation of restrictive rules implied the disruption of social networks, eliciting emotional exhaustion and intense response to fear. This was amplified by media spread of panic and fake news, representing risk factors for post traumatic stress disorder (PTSD). Fear can be dangerous, especially accounting premorbid psychopathological vulnerability, such as pathological personality traits. Emotional dysregulation increases fear levels, mediated by the relationship between emotional dysregulation and lack of tolerance.

Objectives

Clinical case presentation of patient who developed dissociative and behavioral symptoms following COVID-19 infection. Bibliographic research.

Methods

Bibliographic research using Pubmed®. Clinical file consultation and patient interviews.

Results

Heightened psychophysiological reactivity can result from the persistent fear experienced during a traumatic event and repeated memories related to it, leading to a sensitization of the response to fear. We present 57 year-old female patient, admitted to the COVID ward after trying to escape from home isolation due to positivity to COVID-19. In the hospital setting she developed dissociative symptoms, trying to escape from the ward and infect other people.

Conclusions

Intense fear responses to COVID-19 are likely explained by poor emotion regulation capacities as well as dissociative mechanisms. Studies have shown that this pandemic was experienced as a real traumatic event and some studies have found that it may lead to the development of PTSD. Pathological personality is positively related to PTSD symptoms, attributable to higher levels of mood instability, cognitive/perceptual disorders, interpersonal dysfunctions and negative affection.

POS0380 EFFECTIVENESS OF REMOTE CARE INTERVENTIONS: A SYSTEMATIC REVIEW INFORMING THE 2022 EULAR POINTS TO CONSIDER FOR REMOTE CARE IN RHEUMATIC AND MUSCULOSKELETAL DISEASES

Background

While the number of patients with rheumatic musculoskeletal diseases (RMDs) is increasing worldwide, there is no adequate increment in the number of health care professionals, leading to the urgent need for new forms of care to take pressure from health care systems.1 2 Telehealth comprises a number of different types of interventions with the scope of performing certain steps of care, ranging from diagnostics to follow-up visits, in a remote manner. The use of remote care is heterogenous and guidance is needed to optimize the combination with conventional face-to-face (F2F) visits.

Objectives

To perform a systematic literature review (SLR) on different outcomes of remote care compared to F2F care, its implementation into clinical practice and to identify drivers and barriers in order to inform a task force formulating the European Alliance of Associations for Rheumatology (EULAR) Points to Consider for remote care in RMDs.

Methods

Prospective, retrospective, and qualitative studies testing different types of remote care in patients with RMDs were included. Medline, Embase and the Cochrane Library were searched through February 28th, 2021. Two reviewers independently performed standardized data extraction, synthesis, and risk of bias assessment.

Results

A total of 2,240 references were identified. Forty-seven studies, consisting of 26 randomized controlled trials, 8 prospective cohort studies, 8 cross sectional studies, and 5 qualitative studies were included.

Fifty-one percent of the studies involved patients with inflammatory RMDs, including rheumatoid arthritis, and spondyloarthritis, while 49% were on patients with non-inflammatory conditions, such as osteoarthritis and fibromyalgia. Remote monitoring (n=35) was most frequently studied, with telephone/video calls being the most common mode of delivery (n=30). Thirty-four studies investigated outcomes of remote care in comparison to F2F care. The most frequently assessed outcomes concerned efficacy and user perception of remote care, with 34% and 21% of studies, respectively, reporting superior results for the remote care intervention.

Time savings and flexibility were reported as major drivers, while inadequate technical knowledge and concerns in data security were the main barriers to implementing remote care. Implementation of remote care methods into clinical practice was not reported by the included studies. The main limitations were the heterogeneity of outcomes and interventions, and the substantial risk of bias (50% of studies with high risk of bias).

Conclusion

Studies on remote care reported similar to partially better results compared to F2F care concerning efficacy, and user perception outcomes, with the limitation of heterogeneity and considerable risk of bias.

OP0001 “I WILL NEVER FORGET THE SHAME I FELT”: A SURVEY TO PEOPLE WITH A RHEUMATIC DISEASE ABOUT INVALIDATION FROM HEALTH PROFESSIONALS AND OTHER PEOPLE

Background

The term invalidation refers to the patients’ perception that their medical condition is not recognised, either in denying, lecturing, not supporting or not acknowledging the condition. This may be the felt from health professionals themselves but also from family, friends, at work and in other social areas, imposing great suffering.[1] The European Alliance of Associations for Rheumatology (EULAR) has made efforts to raise awareness for the burden imposed by rheumatic and musculoskeletal conditions (RMDs) and promote the best quality of care, including recognition and psychosocial support. However, it is unclear how frequent and severe the problem remains nowadays.

Objectives

The aims of this national survey were: (i) to identify the levels of invalidation and lack of understanding felt by adults with RMDs from health professionals and other people, (ii) to investigate the relationship between invalidation, sociodemographic characteristics and disease; and (iii) to understand its impact on people’s life and health outcomes.

Methods

An online survey was developed by the national health professionals in rheumatology and patients’ organisations and opened between May and December of 2021. The questionnaire included demographic and disease information, the Illness Invalidation Inventory (3*I),[1] with additional questions in a Likert format and open questions for a detailed understanding of the phenomenon. The 3*I is composed of 8 items, measured from 1 (=never) to 5 (=very often), forming two factors: Discounting (mean of 5 items; lower scores indicating more discounting) and Lack of understanding (mean of 3 items; Higher scores representing higher lack of understanding).

Quantitative data were analysed using descriptive statistics. Associations were tested with a t-student and ANOVA one-way test (Bonferroni correction). Open responses were categorised using the content analysis technique, and themes were defined a posteriori.

Results

From the > 1500 responses obtained, 1410 responses were filled out completely (mean age of 46 years [SD=11], 95% females, 60% with FM, among which 59% were diagnosed in the last 5 years).

Invalidation was reported by 86% of the participants and 70% rated ≤5 on a scale from 0 (nothing) to 10 (totally) on feeling understood by other people. Invalidation was mostly felt from family (56%), health professionals (48%), friends (39%) and social environment (38%). The impact of this invalidation is mainly on the psychological well-being (58%), also reducing seeking health care (41%) and therapeutic adherence (17%), affecting work (41%), and to a less extent, (family) relations (31%).

Figure 1 shows the frequency of responses and means scores on the 3*I items and factors for participants with and without FM. The burden is greater for people with FM, which was statistically significant. People with higher education felt more discounting and more lack of understanding. No differences (p>0.05) were observed for gender or civil status.

Figure 1.

Percentages of responses per type of disease for the eight items of the Illness Invalidation Inventory.

Elucidative expressions of invalidation were shared, mostly by people with FM, encompassing their ability to work and need for social support, faking pain and treatment efficacy, and even intimacy aspects. These emotionally uncomfortable situations can be linked to lesser engagement with healthcare and disease management, and therefore, with worse health outcomes.

Conclusion

Invalidation remains a source of suffering, affecting well-being and health outcomes. Specific awareness and educational campaigns are needed to target this problem on different play-actors.

Semiquantitative analysis of interim 18F-FDG PET is superior in predicting outcome in Hodgkin lymphoma patients compared to visual analysis

PURPOSE

To investigate the prognostic value of interim PET (PETi) in adult HL patients, comparing visual with semiquantitative analysis.

MATERIAL AND METHODS

Retrospective analysis of Hodgkin's lymphoma (HL) patients diagnosed between 2012 and 2016 in the Onco-hematology Department of Instituto Português de Oncologia - Porto (median follow-up: 46.5 months [2.6-66.4]). Fifty-eight patients with available PET at diagnosis (PET0) and PETi data were included. PETi scans were analyzed according to Deauville 5-point scale (5-PS), and cut-off values for changes in maximum standardized uptake value [SUVmax], peak SUV [SUVpeak], metabolic tumour volume [MTV] and total lesion glycolysis index [TLG] between PETi and PET0 were computed using ROC analysis. Visual and semiquantitative data were compared with each other in the prediction of patient outcomes.

RESULTS

Semiquantitative analysis obtained a higher sensitivity for persistent/relapsed disease compared to the 5-PS (70% vs. 10%, respectively), but lower specificity. It also demonstrated better predictive performance for response to first-line therapy (negative predictive value >92%). The positive predictive value was similar for all five measurements. At 60 months of follow-up, there was a significant difference between the progression free survival (PFS) curves of patients with positive and negative PETi according to ΔSUVmax (56.9% vs. 88.0%, p<0.05), ΔSUVpeak (55.9% vs. 88.1%, p<0.05), ΔMTV (35.3% vs. 88.7%, p<0.05), and ΔTLG (42.4% vs. 88.1%, p<0.05). Statistical significance was not reached when considering 5-PS results.

DISCUSSION

PETi interpretation according to a semiquantitative approach appears to discriminate HL patients better than the visual 5-PS analysis. This could allow better detection of persistent or early relapsed disease, while a negative PETi result could support de-escalating therapy intensity.

Psycho-sensory modalities of visual hallucinations and illusions in Parkinson's disease

BACKGROUND

Visual illusions (VI) in Parkinson's disease (PD) are generally considered part of the prodrome towards fully formed visual hallucinations (VH), and classified as minor hallucinations. However, this sequential relationship has not been clearly demonstrated and very little is known about the specific phenomenology of VI in regards to VH. We aimed to describe and compare psycho-sensory modalities associated with VI and VH in PD patients.

METHODS

PD patients with VI (PD-I, n=26) and VH (PD-H, n=28) were included in this case-controlled study. We compared qualitative and quantitative psycho-sensory modalities of VI and VH using the PsychoSensory hAllucinations Scale (PSAS), and demographical and clinical features of each group.

RESULTS

PD-I perceptions were more often colored blots (P=0.05) or objects (P=0.005) compared to PD-H. Conversely, PD-H perceptions were more often described as animals (P<0.001), occurring at night (P=0.03) compared to PD-I. The experienced phenomena were more frequent in PD-H (P=0.02), and lasted longer (P=0.02) than for PD-I, but no between-group difference was observed for other repercussion factors including negative aspect, conviction, impact, controllable nature of the perception. Passage hallucinations and sense of presence were observed in both groups with similar frequencies (respectively P=0.60 and P=0.70). Multivariate analysis adjusting for disease severity or duration confirmed these results.

CONCLUSION

VI and VH in PD have different qualitative sensory modalities, with similar quantitative repercussion for patients, and similar association with modalities such as "sense of presence and passage hallucinations", in contrast to the generally accepted classification of VI as minor VH. REGISTRATION NUMBER: clinicaltrials.gov number NCT03454269.

OP0264-HPR “I LITERALLY CONVINCED MYSELF I WAS GOING TO CATCH IT AND DIE”: LIVED EXPERIENCES OF THE COVID-19 PANDEMIC BY PEOPLE WITH RHEUMATIC DISEASES FROM FOUR EUROPEAN COUNTRIES

Background:

The COVID-19 pandemic has resulted in unforeseen challenges for humanity, taking a significant toll, especially the immune-suppressed individuals. In this regard, the health and general well-being of people with rheumatic diseases, the great majority users of immunosuppressives, have been at stake.

Objectives:

To explore the impact of the COVID-19 pandemic on people with rheumatic diseases on immunosuppression during the first wave, concerning a) (self-)management of their disease; b) interaction with the health care team; c) emotional well-being and d) overall health.

Methods:

A qualitative study was conducted following a phenomenological approach. Adults (>18 years) with a rheumatic disease from four European countries (Cyprus, England, Greece, Portugal). Patients were recruited through patient’s associations and social media and were invited to participate in semi-structured, audio-recorded interview or focus groups, between July - August 2020. Following a pilot study the information provided was transcribed verbatim, anonymized and translated into English where necessary. An inductive approach was adopted to carry out a thematic framework analysis with the assistance of ATLAS.ti to identify key themes and subthemes. Data validation strategies were employed, and Ethical approval and informed consent were obtained.

Results:

Participants were 24 patients (21 women, age range 33 to 74 years) divided by 7 focus-groups and 1 individual interview. Most frequent diagnoses were rheumatoid arthritis (n=7), lupus (n=4), juvenile idiopathic arthritis (n=3).

Three key themes with 3-7 subthemes were identified within the analytical framework, centred around the impact of the Covid-19 on patients’ lives (Figure 1): i) individual person (e.g. fear for myself and family, social isolation and lack of personal freedom, more time with family) ii) health settings (e.g. (un)clear information about risks of contamination, fear or risk of shortages of medication, remote consultations), and iii) work and community (e.g. persistent stress due to mass media exposure, lack of awareness by others about patients’ rheumatic disease and its disclosure, hope and suspicion about new vaccine development: “I hear that they will ask vulnerable groups to have the vaccine first (...) Why is that? we will be again the innocent victims”). Findings were similar across countries, except for spirituality (i.e. the pandemic as “the hand of God”), a coping subtheme particular to Portugal. These main themes resonated well with the social ecological model and Walsh’s Family Resilience Process [1,2].

Conclusion:

When experiencing a significant life-event people require some time to process the different lived experiences. This study provides insights on how patients from four countries coped with the new challenges. Such insights are invaluable for health care providers and policy makers, in guiding more meaningful support tailored to individual needs, especially at times of crisis. The study highlights the impact of COVID-19 on the lives of people with rheumatic disease. A follow-up study is currently underway to examine the effect of subsequent waves of the pandemic.

Nutritional value and sensory properties of common carp (Cyprinus carpio L.) fillets enriched with sustainable and natural feed ingredients

Declines across global fishery stocks forced aquaculture feed manufacturers to search for new and sustainable components. Therefore, the aim of study was assessing nutritional value and sensory properties of meat of common carp (Cyprinus carpio L.) fed for 116 days with two blends. The control feed contained 5% of fishmeal and vegetable oils (rapeseed and soybean) as sole fat sources. While in the experimental diet half of the fishmeal was replaced with a blend of microalgae (Spirulina sp., Chlorella sp.), macroalgae (Laminaria digitata) and vegetable oil was replaced with salmon oil. Proximate composition, energy value, fatty acid profile of meat, nutritional characteristics of fat and protein as well as culinary properties of fillets were assessed. Fillets of carp fed experimental diet had a higher level of protein, lower level of fat and energy value. Intramuscular fat of fish fed with the experimental diet had a better parameters of quality. Protein in the meat of fish from both groups was characterized by a high quality comparing to the protein standard. Our study showed that meat of carp fed with experimental feed enriched with sustainable and natural feed ingredients can be a sensorily attractive source of nutritious ingredients in the human diet.

Impacts of social distancing during the covid19 pandemic on the development of children with autism in Brazil

Introduction

COVID-19 is a respiratory disease and its main symptoms are fever, dry cough and difficulty breathing. It spread to several countries, which led the World Health Organization to decree, on March 11, 2020, a pandemic state that deeply affected Brazil. Due to the impossibility of leaving the house, the routine of children with autism was changed. Children in Autism Spectrum Disorder (ASD) have a qualitative deficit in social interaction. Clinical and daily observations reinforce several scientific studies that defend the importance of maintaining a routine as stable as possible for people with ASD, without this stability they may become emotionally disorganized, feel discomfort or even irritability.

Objectives

Investigate the impact caused by social distancing on the development of children and adolescents with autism.

Methods

An online questionnaire based on the DIR/Floortime basic map of emotional functional capacity development was distributed in Brazil from April to May, 2020. The results were analyzed using SPSS software.

Results

Results obtained from 122 questionnaires showed that after 30 days of quarantine 20% of children no longer had the characteristic of being able to remain calm and organized for at least 2 minutes; 11% no longer initiates interactions with their parents; 27% demonstrated more protests and anger than before the social distancing; 18% demonstrated more emotions such as anger, fear and intimacy, 28% began to understand their limits and 12% of the children are using greater facial expression during the social distancing.

Conclusions

This study brings results that can help to understand the processes in a child with autism.

Predictors of the presence of septal late gadolinium enhancement in follow-up cardiac magnetic resonance imaging and its relation to acute myocarditis prognosis

Funding Acknowledgements

Type of funding sources: None.

Introduction

Acute myocarditis (AM) is generally a self-limited and benign disease. However, a minority of patients (pts) present or develop adverse outcomes. It has been proposed that the presence of late gadolinium enhancement (LGE) in the septum is associated with worse prognosis. Also, the presence of LGE without oedema in follow-up cardiac magnetic resonance imaging (CMR) seems to reflect more permanent lesions.

Purpose

The aim of this study was to determine if the presence of septal LGE in acute-phase CMR was associated with higher extent of disease in follow-up CMR and if initial laboratory tests help to predict the evolution to more permanent lesions.

Methods

Prospective single-centre study of pts admitted with AM diagnosed according to clinical findings, troponin T elevation and CMR criteria (Lake Louise), since 1/2013. Selection of those who underwent acute-phase (CMR-I) and follow-up CMR (CMR-II).

Results

Of 88 pts admitted with AM, 46 fulfilled our inclusion criteria: median age 31 ± 13 years, 85% males. CMR-I was performed at 6 ± 5days and LGE was present in 43 pts (93.5%). CMR-II was performed at 8 ± 4.3 months and 29 pts (63%) improved the number of LGE-positive segments, 10 pts (21.8%) had stable disease and 7 pts (15.2%) worsened CMR findings. Septal-LGE was detected in 10 pts (21.7%) in CMR-I and in 6 pts (13.0%) in CMR-II. Logistic regression analysis identified septal-LGE in CMR-I as a predictor of higher extent of LGE in CMR-II (OR 1.4, 95%CI 1.1-1.9, p = 0.020). Although median values of maximum high-sensitivity troponin and reactive-C protein (RCP) were not associated with septal LGE in CMR-I, increasing values of such tests were univariate predictors of a higher likelihood of septal involvement in CMR-II: maximum troponin (886 vs 1852ng/L; OR 1.00, 95%CI 1.00-1.00 p = 0.017) and RCP (4.2 vs 13.9mg/dL; OR 1.17, 95%CI 1.04-1.33, p = 0.012). After multivariate analysis, RCP was the independent predictor of septal LGE in CMR-II (AUC 80.8, 0.97-0.91, p = 0.012). RCP cut-off value &gt;10.2mg/dL identified patients with septal LGE in CMR-II with a sensitivity and specificity of 83.3% and 85.0%, respectively. The presence of cardiovascular risk factors, clinical presentation and B-type natriuretic peptide values were not predictors of septal LGE in either CMR. In a mean clinical follow-up of 757 ± 476days, no patient died, 3 pts (6.5%) developed new-onset heart failure (NYHA class II functional symptoms) and 2 pts (4.3%) developed ventricular arrhythmias. Due to a small number of adverse events, neither laboratory tests nor LGE septal pattern predicted adverse outcomes.

Conclusions

In this population, septal LGE pattern was able to predict higher extent of LGE in follow-up CMR. Increased cardiac biomarkers and inflammatory proteins in the acute setting were also associated with septal involvement in follow-up and can potentially help to establish the risk of adverse events for patients admitted with acute myocarditis.

Introduction

The CHA2DS2-VASc score is used in clinical practice to stratify the risk of stroke in patients (pts) with atrial fibrillation (AF). Its usefulness in the population of pts with acute myocardial infarction without AF is not well known.

Objectives

To investigate whether CHA2DS2-VASc predicts ischemic stroke and death during hospital stay in pts with acute myocardial infarction without known AF. To determine independent predictors of ischemic stroke in this population.

Methods

A multicentre, retrospective study was performed during 01/10/2010-04/09/2019 period, and included all pts admitted due to acute myocardial infarction. Pts with previous AF, AF rhythm in the electrocardiogram at admission or AF during hospital stay were excluded. Statistical analysis with Kaplan-Mayer and Cox regression was applied.

Results

Of 29851 pts admitted with acute myocardial infarction, were included in our study 19218 pts (74% male, mean age of 65 ± 14 years). 

During hospital stay, 78 (0.4%) pts had an ischemic stroke and 462 (2.4%) pts died. 

The event-free survival analysis showed significant differences according to the CHA2DS2-VASc score at admission (log rank test p = 0.015 for ischemic stroke; log rank test p &lt; 0.001 for in-hospital mortality). (Figure) 

The CHA2DS2-VASc score demonstrated a good predictive accuracy for in-hospital mortality (area under the ROC curve 0.69; 95% CI 0.67-0.72; p &lt; 0.001). The area under the ROC curve indicates that the CHA2DS2-VASc score performed modestly for ischemic stroke (0.62; 95% CI 0.56-0.68; p &lt; 0.001). 

In univariate analysis, the factors that were positively associated with ischemic stroke during hospital stay were CHA2DS2-VASc, absence of previous therapy with statin, time between cardiac symptoms and hospital admission, absence of chest pain, Killip-Kimball class, cardiorespiratory arrest, complete left ventricular block and left ventricle ejection fraction &lt;50% (p &lt; 0.05). 

After multivariate analysis, CHA2DS2-VASc≥3 (HR 2.25; 95% CI 1.37-3.71; p = 0.001), absence of chest pain (HR 3.17; CI 1.44-6.14, p &lt; 0.001) and previous therapy with statin (HR 0.39; 95% CI 0.22-0.67; p = 0.001) were independent predictors of ischemic stroke.

Conclusion

 Among patients with acute myocardial infarction without known atrial fibrillation, the CHA2DS2-VASc score was associated with risk of ischemic stroke and death during hospital stay. This score may be useful for estimating the risk of stroke and in-hospital mortality in these population without known atrial fibrillation.

Saliva pools for screening of human cytomegalovirus using real-time PCR

Human cytomegalovirus (HCMV) is the leading congenital infection agent in the world. The importance of screening this infection has been debated, as 10-15% of the asymptomatic newborns with HCMV at birth will present late sequelae. The aim of this study was to test the feasibility of using saliva pools from newborns in a screening program for congenital HCMV infection, in two Portuguese hospitals. The screening was based on the use of pools of 10 saliva samples for detection of viral DNA by real-time PCR. Whenever there was a positive pool, the samples were tested individually, and for each positive sample the result was confirmed with a urine sample collected in the first 2 weeks of life. The study involved 1492 newborns. One hundred and fifty pools were screened, with 14 positive results in saliva, but only 10 were confirmed in urine samples, giving a prevalence of congenital HCMV infection in both hospitals of 0.67% (CI95% 0.36 to 1.23%).Conclusion: The overall prevalence of congenital HCMV infection in both hospitals was 0.67%. The use of saliva pools proved to be effective for the screening of this congenital infection, allowing timely screening and confirmation in a large population, with associated cost reduction. What is Known: • Newborn screening for HCMV is desirable. • Saliva is a good and practical sample. What is New: • The feasibility of using saliva pools for a large-scale screening. • The cost reduction of this strategy.

The 90s are the new 70s: approach to nonagenarian patients with myocardial infarction: data from the Real World Portuguese Registry on Acute Coronary Syndromes (ProACS)

Introduction

The approach to Acute Coronary Syndromes is based on robust high quality evidence, currently systematized in European endorsed guidelines. However most trials that support such guidelines excluded or included a small percentage of the very elderly, namely nonagenarian patients, and the clinical decision in this age range is subjected to high interpersonal and inter-hospital variability.

Purpose

Our aim was to assess the approach to nonagenarian patients with Acute Coronary Syndromes (ACS), in what regards the choice of percutaneous coronary intervention or conservative management and determine in-hospital and at 1 year outcomes.

Methods

We performed a 9 year retrospective analysis of all patients with age equal or greater than ninety (90) admitted with ACS in Portugal. Medical records were analysed for demographic, procedural data and outcomes.

Results

Seven hundred and fourteen (714) nonagenarian patients were admitted with ACS, which corresponded to 2.4% of the total cohort. The mean age was 92±2 with a female preponderance (58.7%). There was a high rate of cardiovascular risk factor with hypertension in 81.3%; Dyslipidemia in 46.1% Diabetes Mellitus in 23.4%; and other comorbidities with 21% of prior ACS, 14.4% with Heart Failure, 11% with cerebrovascular events and 15.4% with chronic kidney failure.

The ACS was categorized as ST elevation Myocardial Infarction (STEMI) in 43.9%, non- STEMI (NSTEMI) in 45.8%, and unstable angina (UA) in 2%.

Two hundred and sixty-eight (268), 37.8% of the cohort, were submitted to percutaneous coronary intervention (PCI), mainly due to STEMI (68.3%). This cohort were composed of patients with less comorbidities (statistically significant less valvular heart disease, heart failure, peripherical artery disease and dementia although more oncological diseases). There was no difference in the severity of ACS, as categorized by the Kilip Kimbal (KK) classification, mechanical complication or depressed ejection fraction between the 2 groups. (p&gt;0.05 for all)

There was a statistically significant increase of advanced atrioventricular block (10.6 vs 4.4%; p 0.002; Logistic regression OR 3.12; IC95 [1.37–7.15], p 0.007) and major bleeding (1.8 vs 5.5%; p 0.008; Logistic regression OR 3.36; IC95 [1.36–8.32] p 0.009) in the PCI group. There was no difference in in-hospital re-infarction, cardiac arrest, stroke or death. (p&gt;0.05 for all)

The follow up at 1 year was performed in two hundred and fifty-six (256) patients, 30.9% submitted to PCI. Although the survival analysis demonstrated a trend towards improvement in 1-year survival and cardiovascular readmissions in the intervention group, it did not reach statistical significance. (p&gt;0.05 for all)

Conclusions

PCI was performed in about a third of nonagenarians presenting with ACS. Our cohort demonstrated a greater rate of in-hospital complications without a significant in-hospital or at 1 year clinical benefit.

Prevalence and prognostic value of right ventricular dysfunction in hypertrophic cardiomyopathy

Introduction

Hypertrophic cardiomyopathy (HCM) is the main cause of sudden cardiac death in the young and a cause of heart failure and death at any age. Nevertheless, adverse long-term outcomes are not easy to predict.

Objectives

To assess the prevalence, predictors and prognostic value of right ventricular (RV) dysfunction in patients (pts) with HCM.

Methods

Retrospective single-center study of consecutive pts with HCM evaluated in a specialized medical appointment. Selected those submitted to cardiac magnetic resonance imaging (MRI) as the gold-standard for RV function assessment. The primary endpoint was a composite of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, ventricular arrhythmias with hemodynamic instability and unplanned heart failure admission.

Results

Were included 112 pts (mean age at first appointment 57±15 years, 63% male). Septal asymmetric phenotype was the most frequent (75%), with a mean septal wall thickness of 18±4 mm. Late gadolinium enhancement was observed in 82%, mostly intramyocardial (67%) and in joint points (47%).

RV dysfunction was detected in 6 pts (5.4%) and RV free wall hypertrophy in 3 pts (2.7%); no patient presented RV dilation.

Factors associated with RV dysfunction were left atria area (HR 1.07/unit, 95% CI 1.01–1.12, p=0.02), left ventricular ejection fraction (HR 0.91/unit, 95% CI 0.86–0.97, p=0.02) and the presence of left ventricle wall motion abnormalities (HR 7, 95% CI 1.3–38, p=0.03) in cardiac MRI.

During a mean follow-up of 60±31 months, the combined primary endpoint occurred in 15 pts (13%), significantly more in pts with RV dysfunction (HR 5.1, 95% CI 1.1–24, p=0.038) (graphic 1). Patients with RV dysfunction also presented more atrial fibrillation / flutter episodes during follow-up (HR 6.4, 95% CI 2.1–20, p=0.001).

Conclusions

Although not common, right ventricular dysfunction was associated with a higher rate of cardiovascular events. These results support a potential role of right ventricular function in the risk stratification of patients with hypertrophic cardiomyopathy.

Substrate guided ablation of idiopathic right ventricular outflow tract premature ventricular contractions in patients with low arrhythmia burden during the procedure

Background

Ablation of premature ventricular contractions (PVCs) is currently based on activation mapping. This strategy is impaired by the absence or paucity of PVCs on the day of the procedure. Frequently, isolated diastolic potentials (DP) are present at the successful ablation site in sinus rhythm (SR), although their meaning is still a matter of debate.

Objective

Evaluate the feasibility and results of a substrate-based approach for ablation of idiopathic right ventricular outflow tract (RVOT) PVCs, in patients that present with a low PVC burden during the procedure.

Methods

We included 12 consecutive patients referred for ablation of frequent (&gt;10000/24 hours) idiopathic PVCs from the RVOT that present with less than 2 PVCs/min in the beginning of the procedure. The ablation was based on fast mapping of the RVOT in SR looking for DPs, defined as isolated small amplitude potentials occurring after the T wave of the surface ECG in SR (Figure). The area with DPs was marked and a reduced activation mapping of the PVCs was done in that area. We evaluated the procedure time, mapping, fluoroscopy and radiofrequency (RF) application times. The number of points used for the maps, the area of DPs, local activation time and success rate. Values are presented as median (Q1-Q3). Electroanatomical mapping of the RVOT in SR was also performed in a control group of 10 subjects that underwent ablation of supraventricular arrhythmias, to evaluate the prevalence of DPs in subjects without PVCs.

Results

The number of PVCs during the procedure was 1 (0.1–1.6)/min. Both groups did not differ in relation to age or gender. Median age 45 (34–65) years, 6 males in the PVC group and 40 (33–65) years, 6 males in the control group, p=0.821 and p=0.231 respectively. The number of points sampled per RVOT map in SR was 400 (193–500) in the PVC group and 330 (277–425) in the control group, p=0.539. All patients in the study group had DPs in the RVOT. None of the control group subjects had DPs in the RVOT. Ablation data is presented in the Table. The acute success rate was 100%. After a median follow-up time of 4 (3–6) months one patient had recurrence.

Conclusion

In these group of patients with very low PVC burden during the procedure, this approach partially based on substrate mapping, made ablation of the PVCs feasible, in a fast and efficient way.

Trends in tobacco use among children and adolescents in Israel, 1998–2015

Objectives

This study aims to measure trends in cigarette smoking among children and adolescents in Israel, focusing on school grade, sex, and ethnicity. We hypothesized that smoking would be higher among boys and Arab-Israelis, rates would grow with age, and there would be a decline over time.

Methods

Data were derived from the Health Behavior in School-aged Children study between 1998-2015 in Israel. The total sample included 56,513 students in grades 6, 8, and 10, with 29,411 girls and 27,102 boys. Descriptive analysis described trends of smoking behavior according to grade, sex, ethnicity, family affluence, and year of study. Multivariate logistic regression analysis examined predicting variables.

Results

Smoking was higher among boys in all grades, ethnic groups, and years of study, with the highest frequencies among Arab-Israelis. Trends over the years show a decline from 1998-2004, followed by an increase for both sexes. The increase was more prominent among girls. Logistic regression analysis revealed strong associations between smoking and grade, sex, ethnicity, and year of study.

Conclusions

The results of this study can significantly enhance the development and implementation of smoking prevention and control programs among students in Israel.

Key messages

Our calibrated results engender important policy implications for the development of cigarette smoking prevention programs for Israeli youth, specifically in the school environment. health inequities needs to be a key part of a comprehensive strategy when discussing health promotion and development.

Predictive equations of maximum respiratory mouth pressures: A systematic review

BACKGROUND

Maximum inspiratory (Pimax) and expiratory (Pemax) mouth pressures are commonly used to detect respiratory muscle weakness resorting to predictive equations established for healthy people. There are several predictive equations, but they are widespread in the literature. This study aimed to review the existent predictive equations of maximum inspiratory (Pimax) and expiratory (Pemax) mouth pressures for adults. Additionally, we aimed to identify which ones were generated based on international standards.

METHODS

A systematic review of predictive equations of Pimax and Pemax for healthy adults was conducted. A comprehensive search was performed of Cochrane Library, EBSCO, PubMed, Scopus and Web of Science to identify studies that presented at least one equation for Pimax or Pemax developed for healthy adults. The quality of studies was assessed by two reviewers with the Quality Assessment of Diagnostic Accuracy Studies (Quadas-2).

RESULTS

Risk of bias was high in 8 of the 20 studies included. Forty-two Pimax and 34 Pemax equations were found, mostly using the variables age (n=39), weight (n=20) and height (n=8). These equations explained 3 to 96% of the Pimax/Pemax variance. They were developed with individuals from 11 countries (Portugal not included). Twelve Pimax and eight Pemax equations complied with international standards.

CONCLUSIONS

This review gathered the predictive equations that have been developed for both Pimax and Pemax, however most were generated from unstandardized procedures. Future studies should explore the suitability of these equations for populations for which specific ones are not available, such as the Portuguese population, and develop new equations if necessary.

AB1304-HPR KNOWLEDGE OF HIGH SCHOOL STUDENTS ABOUT RHEUMATIC DISEASES: EFFECT OF AN EDUCATIONAL SESSION JOINTLY PROVIDED BY PORTUGUESE EULAR ASSOCIATIONS

Background:

International studies have shown that the awareness and knowledge of the general population about rheumatic and musculoskeletal diseases (RMDs) is poor. This is even lower in the young population, which are also affected by these disease but do not have as much awareness campaigns as adult community. Their professors and primary health care professionals may also play here also a key role, promoting early detection of signs and interpretations of symptoms, thus avoiding late health care referrals and diagnosis. (Vlieland, 2016).

Objectives:

To assess the knowledge of high school Portuguese students about the RMDs and raise awareness for RMDs in young people, their professors, vigilants, and primary care nurses, within the school environment.

Methods:

A 1-hour educational session about RMDs was planned (with the inputs from members of the Portuguese EULAR Associations) and performed during school activities. The educational session started with a knowledge questionnaire about RMDs in a paper sheet (9 questions; Graph 1), repeated in the end. An interactive session, using slides, interactive questions (Sli.do®), and practical demonstrations to simulate RMD symptoms (e.g. stiffness and functional limitations) was then lead by a rheumatology nurse, with the testimony from a young patient representative. A primary care nurse assisted in order to be engaged and promote future sessions (“autonomously”). Change in knowledge was assessed with Wilcoxon-test and awareness was documented with “word clouds” (using Sli.do®).

Results:

A total of 75 students participated in four sessions (mode=16 years). Half of students (52%) had never heard about RMDs. Knowledge increased significantly in all questions (p<0.001; Graph 1). Figures 1 and 2 document the most common words representing what defines a RMD and what are the main symptoms, respectively.

Conclusion:

Our results confirm that awareness and knowledge about RMDs are very low high school students. The single and educational session was very well received by all students, and the the knowledge increased. Post-educational feedback was that students especially liked the testimony of a peer. Other sessions are taking place in primary schools.

SAT0608-HPR EULAR POINTS TO CONSIDER FOR THE DETECTION, ASSESSMENT AND MANAGEMENT OF NON-ADHERENCE IN PEOPLE WITH RHEUMATIC AND MUSCULOSKELETAL DISEASES

Background:

Non-adherence to medication and non-pharmacological interventions precludes reaching an optimal outcome. 30 to 80% of patients with rheumatic and musculoskeletal diseases (RMDs) do not adhere to their recommended treatment regimens.

Objectives:

The objective of this EULAR task force was to establish recommendations/points to consider (PtC) for the detection, assessment and management of non-adherence in people with RMDs.

Methods:

A EULAR task force (TF) was established, and the EULAR standardised operating procedures for the development of PtCs were followed. The TF included rheumatologists, health professionals in rheumatology (HPRs), and patient-representatives from 12 countries. A systematic literature review of reviews was conducted in advance to support the TF in formulating the PtC. Agreement was obtained by Delphi technique in three rounds (0-10 rating scale).

Results:

A definition of adherence, 4 overarching principles and 9 PtC were formulated (table).

Conclusion:

The PtCs can help health-care providers to support people with RMDs to adhere to the agreed treatment plan.

Table.

Overarching principles and points to consider.

Definition of AdherenceAdherence is defined as the extent to which a person’s behaviour corresponds with the agreed prescription.Overarching principlesAgreement1Adherence impacts the outcomes of people with RMDs.992Shared decision making is key, since adherence is a behaviour following an agreed prescription.963Adherence is influenced by multiple factors.984Adherence is a dynamic process that requires continuous evaluation.96Points to considerAgreement1All HCPs involved in the management of people with RMDs should take responsibility for promoting adherence.992Effective patient-health professional communication should be applied to enhance adherence.993Barriers and facilitators of adherence of a specific patient to a specific prescription should be appropriately evaluated.954Patient education should be provided for people with RMDs as an integral part of standard care.965Care should be tailored to patient preferences and goals to enhance adherence.986Adherence should be discussed regularly based on open questions and particularly when disease is not well controlled.997The HCP should explore which factors might negatively influence adherence, including: opportunity (e.g., availability or cost), capability, (e.g., memory problems), motivation (e.g., concerns).948Together with the patient, the HCP should tailor the approach to overcome individual barriers to adherence, e.g.,98- simplifying the regimen,- using reminders,- providing education,- discussing the patient’s beliefs on treatments.9When specific expertise or interventions for adherence are needed, they should be made available to patients.98

Plasma biochemistry, gene expression and liver histomorphology in common carp (Cyprinus carpio) fed with different dietary fat sources

Demand for omega-3 long chain polyunsaturated fatty acids has become global challenge for aquaculture and different components have been used to increase nutritional value of fillets. The aim of this study was to evaluate influences of feeds on zootechnical parameters, biochemical plasma parameters, expression of lipid-dependent genes, hepatocyte histomorphologies, and fatty acid profiles in common carp fillets. We compared a control diet (CTRL), mimicking a commercial feed formulation for common carp, with three diets containing blends of vegetable oils and a DHA-rich alga (Schizochytrium sp.) included at 3.125% (CB1) or 1.563% (CB2), and 2.1% salmon oil (CB3). The study revealed no differences in final body weight of fish fed CB1-3 diets in comparison with significantly lower CTRL. Concentrations of all biochemical parameters in plasma increased gradually in fish fed CB1-3 diets when compared to CTRL diet, with exception of triacylglycerol levels. Expression of hepatic fas, elovl-5a and pparα genes increased significantly in fish fed CB1 and CB2. Additionally, eicosapentaenoic (EPA) and docosahexaenoic acid (DHA) accumulation in muscle tissue was directly proportional to the amounts supplied in the diets. Our study revealed that carp fillet profiles can be manipulated for DHA and EPA-contents using enriched diets, depending on the source of fat.

Enhancing the assessment of cardiorespiratory fitness using field tests

OBJECTIVE

To establish normative values and reference equations of the 6-minute walk test (6MWT), incremental shuttle walk test (ISWT) and unsupported upper limb exercise test (UULEX) for Portuguese adults.

DESIGN

Cross-sectional study. Descriptive statistics and differences between age decades and genders were explored using univariate general linear models to compute reference values. Reference equations were established with a forward stepwise multiple regression.

SETTING

General community.

PARTICIPANTS

In total, 645 adult volunteers without disabilities [43% male, mean age 55.1 (standard deviation 23.6) years] were recruited from the university campus and surrounding community.

INTERVENTION

Not applicable.

MAIN OUTCOME MEASURES

Data on age, gender, height, weight, body mass index and smoking status were collected using a structured questionnaire. Physical activity was evaluated using the Brief Physical Activity Assessment Tool. Participants performed two repetitions of the 6MWT, ISWT and UULEX, and the best repetition was used for analysis.

RESULTS

Overall, performance was better in males than in females, and decreased with age. Participants' performance was significantly reduced after the sixth decade of life compared with the other decades (P<0.001). Reference equations were: 6MWT=226.93-(5.00×age)+(360.41×height), R²=71%; ISWT=393.81-(17.98×age)+(185.64×gender)+(775.88×height), R²=83%; and UULEX=16.71-(0.14×age)+(2.66×gender), R²=57%.

CONCLUSION

Leg or arm exercise field tests are affected significantly by age and gender. These results will aid health professionals to interpret the results of field tests obtained from healthy or diseased adult populations.

475 A rare cause of right ventricular mass

Introduction

Intracardiac masses are always a challenging diagnosis, especially when it involves the right side of the heart. There are multiples etiologies that can be responsible for these masses, namely thrombosis, neoplasm or vegetations. Occasionally, these may be related to an autoimmune process not yet discovered.

Case Report

17-year-old male, with a previous history of genital ulcers, medicated with penicillin with complete resolution of symptoms.

In January 2019, he started an history of recurrent fever, associated with right anterior thoracalgia, weight loss and oral afthosis. He went to the emergency department several times, where he was medicated with antibiotic, with partial symptom relief.

Three months later, he returned to medical attention due to an episode of abundant hemoptysis, followed by hematemesis and cough. At hospital admission, he was hemodynamically stable, tachycardic (100/min) and with occasional episodes of cough. Cardiac and pulmonary auscultation were unremarkable. Thoracic CT revealed the presence of pulmonary thromboembolism (PTE) and a large mass in the right ventricle (RV). It was performed an echocardiogram (echo) that confirmed the presence of a large mass in the RV (50x53mm) from which a projecting hypermobile mass appeared to prolapse into the right atrium.

Taking into account the diagnosis of PTE and the presence of a right ventricular mass, the patient was hospitalized and started anticoagulation. The case was immediately discussed with cardiac surgery, that confirmed that there was no surgical indication. During hospitalization, there were no more episodes of hemoptysis or hematemesis.Consecutive echos were performed, that did not reveal a significant decrease in mass dimensions despite anticoagulation. Viral serologies and autoimmunity panel were all negative. Cardiac RMI was performed raising the suspicion of a possible mass covered with thrombus.

After discussion with rheumatology, and according to clinical signs, the hypothesis of vasculitis was placed, and the patient started treatment with steroids. This treatment had to be suspended after a few days due to an infectious intercurrence. After a course of antibiotic therapy, the patient started therapy with cyclophosphamide with good clinical and echocardiographic response (reduced mass dimensions).

It was admitted Behçet’s disease with cardiac complications, and the patient was referred to the rheumatology consultation.

Conclusion

Behçet’s disease is a multi-system, chronic disorder that behaves like vasculitis.There are some typical clinical manifestations associated with this disease, such as oral and genital afthosis, uveitis, arthritis, skin lesions and nervous system involvement.Presentations with cardiac symptoms are one of the extremely rare manifestations of this disease, posing a challenge for the treating physician.

P794 Treadmill exercise stress echocardiography in children; our experience

Background

Exercise stress echocardiography (ESE) is routinely used in adults but its role in children (C) is less established

Purpose

To assess the feasibility and clinical value of ESE in outpatient children

Methods

We enrolled 309 consecutive C (mean age = 14,1 ± 2,6 years, range 6-17 yrs) who underwent treadmill ESE between 2002 and 2019: One group (Group I) of 258 C including: 237 with exercise related symptoms (chest pain and/or dyspnea and/ or lypotimia-syncope), 15 with resting ECG alterations, 6 with positive ECG stress test and other group of C (Group II) including: 10 asymptomatic for screening requested by parents, 11 with symptoms unrelated to exercise, 12 with antecedents of sudden death in the family, and 17 with known pathology - 10 with hypertrophic cardiomyopathy, 2 with aortic coarctation, 1 each with Cortriatriatum sinister, pulmonary stenosis, subaortic stenosis, bicuspid aortic valve, left ventricular hypertrophy related to arterial hypertension, aortic switch operation. Regional wall motion abnormalities (RWMA) by 2-D and continuous wave Doppler (transvalvular or transaortic or intraventricular (IVG) gradients were assessed in all.

Results

The success rate was 309/309 (100%). Only one complication (allowing asthma diagnosis by serendipity) occurred: a severe asthmatic crisis in one girl studied because of chest pain with exercise (with ESE negativity), Stress-induced RWMA occurred in 2 pts (one with HCM, the other with normal coronary arteries). A significant orthostatic exercise induced IVG (&gt; 30 mmHg) was present in 101 of the 258 C (39%) studied due to symptoms, ECG alterations or positive stress ECG.

In group II the C with induced IVG attained

greater heart rate (HR) 184 ± 12 vs 174 ± 16 (p &lt; 0,001); greater blood pressure (BP) 150 ± 19 mmHg vs 136 ± 23 mmHg (p &lt; 0,001). The OR to the reproduced symptoms that motivated the exam during the SE comparing the 101 C with IVG with the 158 without IVG was 8,22 (4,83-13,99) p &lt; 0,001 (95% CI).

Conclusions

Treadmill ESE is feasible and safe in young people. RWMA are of limited usefulness in our outpatient C group. Doppler often documents significant exercise induced IVG, occult at rest that associate with symptoms.

P945 Should children, with exercise induced intra-ventricular gradients, be treated with beta blockers?

Background

In our experience, treadmill exercise echocardiography (SE) is feasible and safe in children (C). Regional wall motion abnormalities (RWMA) are of limited usefulness, but Doppler often - (in 39% from 258 previously studied C) - documents significant intraventricular gradients (IVG), occult at rest, and allowing to document a possible explanation for exercise related symptoms, or abnormal resting or stress-ECG findings.

Purpose - To assess the effect of ß blockers on the occurrence of IVG, in C, with symptoms or abnormal resting or stress-ECG findings.

Methods – We repeated SE in 66 of the 101 C – (with normal echocardiogram at rest) - that developed IVG on exertion, under treatment with ß blockers. These 66 C who repeated the SE under treatment with ß blockers are the study group. 15 (23%) of them were female and the mean age of the group was 14,6 ± 1,7 years old (11 to 17).

They all underwent SE with 2D and Doppler echocardiographic evaluation of, and during treatment with ß blockers.

Results

Mean IVG in those 66 C submitted to SE was 105 ± 38 mmHg in the first SE evaluation. In SE evaluation performed under ß blockers, 37 of them didn’t develop IVG and in 29 of them IVG was significantly reduced to a mean IVG of 58 ± 32 mmHg (p&lt; 0,0001). The mean heart rate attained at peak exercise was 178 ± 15 bpm in the first SE evaluation and 157 ± 9 bpm in the evaluation performed under treatment with ß blockers (p &lt; 0, 0001). 47 of these C reproduced clinical symptoms (that were indication to SE) of beta-blockers, and only 7 reproduced the symptoms under treatment with beta blockers (p&lt; 0,0001).

Conclusions

In C with symptoms, abnormal rest or exercise ECG on medical evaluation and IVG on exertion, treatment with oral ß blockers prevented the occurrence of IVG or significantly reduced its magnitude. These changes were associated to significant clinical improvement in 85 % of the symptomatic population.

107 Low-flow low-gradient aortic stenosis: aortic valve area estimated by continuity equation versus simplified method of projected aortic valve area

Introduction

The evaluation of real severity of "low-flow low-gradient" aortic stenosis (LFLG AS) is particularly challenging. TOPAS study demonstrated that projected aortic valve area at a normal transvalvular flow rate (AVAproj) derived from dobutamine stress echocardiography (DSE) is superior to the traditional Doppler indices to discriminate true severe-AS and pseudosevere-AS.

Purpose

To compare two echocardiographic methods to estimate severity of LFLG AS with DSE (aortic valve area (AVA) estimated by continuity equation (AVA-CE) and simplified method of AVAproj) in patients (pts) with low transvalvular flow rate (&lt;250mL/seg).

Methods

Unicentric, retrospective study, that included pts with LFLG AS undergoing DSE with low dose dobutamine protocol, during Nov 2013-Dec 2018 period. Evaluation at rest and peak DSE of vital signs, mean transaortic gradient, aortic VTI, LVOT VTI and VTI ratio, valvulo-arterial impedance (ZVA), AVA-CE, simplified method of AVAproj and global longitudinal strain (GLS).

Results

A total of 27 DSE were performed in 23 different pts, mean age of 76 ± 8 years, 82% male. At rest 55% in sinus rhythm, mean heart rate (HR) was 76 ± 12 bpm, mean systolic arterial pressure (SAP) was 122 ± 22 mmHg, mean ZVA 4.3 ± 2 mmHg/ml/m2; mean diameter of LVOT was 21,7 ± 2,6cm, mean of mean aortic gradients 21 ± 7 mmHg, 67% of pts had a VTI ratio at rest compatible with severe AS and remaining compatible with moderate AS. Estimated mean AVA-CE was 0.86 ± 0.29 cm2 with 67% of pts classified as severe AS. Mean left ventricular ejection fraction at rest was 31 ± 9%, systolic volume index 28,7 ± 8 mL/m2 and GLS -5,9%.

During low dose perfusion protocol of dobutamine

100% patients remained asymptomatic, mean HR was 110 ± 25 bpm, mean SAP was 123 ± 26 mmHg, mean ZVA 3.6 ± 1.7 mmHg/mL/m2, mean of mean aortic gradients 28 ± 9mmHg, 37% of pts presented VTI ratio compatible with severe AS and remaining compatible with moderate AS. Mean flow reserve was 16 ± 16% and mean GLS-7.2%. AVA-CE was 1,06 ± 0,35 cm2 with 56% of pts classified as severe AS and mean projected AVA was 1.01 ± 0.22cm2, without significant difference in AVA estimated by the two methods (p = 0.344). Projected AVA allowed re-classification of AS in 22% of pts (5 patients), with 31% of severe AS reclassified as moderate AS while AVA-CE allowed re-classification in 13% (3 patients), with 19% of severe AS reclassified as moderate AS.

Considering medium follow up of 24 months, 6 patients were submitted aortic valve replacement surgery and another 6 patients to transcatheter aortic valve replacement. The simplified projected valve area calculation show no significant therapeutic impact in the selection of this patients.

Conclusion

The simplified projected valve area calculation is technically feasible and accessible. This study shows a good correlation in pts with low cardiac flow. If AVAproj method had been used 2 extra patients would have been reclassified during DSE.

P1808 The impact of valve type in morbimortality of patients with infectious endocarditis

Introduction

Infectious endocarditis (IE) represents one of the main causes of morbimortality in patients (pts) with valvular heart disease. Prosthetic valves infection is usually associated with worse outcomes.

Aim

To compare the clinical features and adverse outcomes of patients with native vs prosthetic valve IE.

Methods

We analysed a population with suspected/confirmed IE, according to Duke criteria, in the last 12 years (2006-2017). The clinical and imaging data were collected as well as complication rates and mortality data.

Results

174 pts, 75% males with mean age of 61 ± 16 years. Native valve EI occurred in 74,1%. of pts. 25,3% had heart failure (HF), 16,1% chronic kidney disease(7,1% on haemodialysis), 12,8% HIV infection, 9,3% active neoplasm and 7,1% were on immunosuppression. 16 pts with native valve disease had previous valvular disease: 1 congenital valve disease, 2 with rheumatic heart disease, 3 with previous IE and 10 with degenerative disease. At admission: 73,1% had fever, 53,2% murmur and 47,9% anemia. The majority (78,4%) had single valve IE and 15,8% had double valve involvement. Aortic valve (AoV) was affected in 54% of the cases and mitral valve involvement was seen in 43,7%. 13,3% had right valve disease. S. Aureus was the most frequent microrganism. Echocardiographic findings: 87,7% had vegetation, 21,2% valve destruction , 5,6% valve obstruction, 14,3% abscess, 3,7% valve aneurysm, 5,6% pseudoaneurysm and 5,6% fistula. Regurgitation was observed in 62,1%. The intrahospitalar mortality was 29,9%.

Comparing both groups, pts with prosthetic IE had more previous history of HF (40,5% vs 20,5% p = 0,009) and diabetes (31,7% vs 15,3% p = 0,020). No differences were found in what concerns microrganisms involved.

Echocardiographically, pts with prosthetic valve had predominantly AoV involvement (81,1% vs 45,5% p &lt; 0,001), less vegetation (75% vs 91,8% p = 0,01) and less regurgitation (45% vs 67,8% p = 0,01). They had more local complications (61% vs 27,7% p&gt; 0,001) like valve obstruction (12,5% vs 3,3% p = 0,043), abscess (32,5% vs 8,3% p&gt; 0,001) or pseudoaneurysm (17,5% vs 1,7% p= 0,001).

In what concerns morbidity burden, developed more HF during hospitalization (56,1% vs 37,7% p= 0,037) as well as more isquemic and haemorragic stroke(85,7% vs 42,3%. P = 0,004 and 28,6% vs 2,4% p = 0,012, respectively). However there were no differences regarding the development of septic shock (p = 0,542) or overall embolization (p = 0,732). At last, no differences were found in intrahospitalar(IH) mortality (p = 0,085), relapse (p = 0,573) or overall survival between both groups (log rank: 1,5, p = 0,217).

Conclusion

Pts with prosthetic valve IE usually have worse outcomes. However,for this population,we conclude that besides having more HF and stroke, there were no differences in what concerns septic shock or overall embolization, as well as IH mortality and survival between both groups.

P829 Cardiac uptake level in 99mTc-DPD scintigraphy in ATTR amyloidosis: is there any association with the prognosis?

Introduction

The uptake of bone-seeking radiotracers in 99mTc-DPD scintigraphy has been shown to be highly sensitive for cardiac transthyretin (ATTR) amyloid. Progressive levels of cardiac involvement are associated with poor prognosis.

Purpose

Evaluation of the prognostic impact of the tracer uptake level in the heart through 99mTc-DPD scintigraphy.

Methods

Single center retrospective analysis of patients’ data referred to perform a 99mTc-DPD between September 2014- July 2018 due to an abnormal echocardiogram or family history of ATTR. Data was collected regarding clinical, echocardiographic and 99mTc-DPD parameters to evaluate prognostic impact of the uptake level on cardiovascular events, namely hospitalizations due to acute heart failure, myocardial infarction or stroke, and all-cause mortality.

Results

35 patients were reviewed of whom 12 (34.3%) had a positive 99mTc-DPD, performing the diagnosis of an ATTR amyloidosis: mean age 78.4 ± 7.3 years, 100% male. 33.3% had a cardiac uptake level 2 (group 1) and 66.6% level 3 (group 2). Group 1 patients were younger (mean age 72.3 ± 4.6 versus 81.5 ± 6.5 years, p 0.03). At the time of diagnosis, most patients in both groups were in NYHA class II. Mean value of NTproBNP in group 1 patients was 4322.4 ± 35.0 versus 6387.7 ± 60.0 pg/ml (p 0.03); troponin level was not statistically different between groups (88.3 ± 63.1 versus 54.5 ± 16.1 pg/ml, p 0.228). On transthoracic echocardiogram evaluation, there were no significant differences between groups regarding cardiac function: mean ejection fraction 48.8 ± 6.3 versus 43.9 ± 11.5% (p 0.453) and mean global longitudinal strain -10.4 ± 2.8 versus -9.0 ± 2.9% (p 0.531). Although almost patients presented a nearly normal ejection fraction, almost have diastolic dysfunction (75 versus 100%, p 0.140) and pericardial effusion (100% in both groups). Hypertrophy level was similar between groups: septum thickness was 19.5 ± 0.7 in group 1 and 19 ± 1.4mm in group 2 (p 0.386). During follow-up, 25% of group 1 patients were hospitalized due to acute heart failure and 25% died. In group 2 patients, there were 25% of hospitalizations due to heart failure and all-cause mortality rate of 50%.

Conclusions

In our population, there was no significant association between the cardiac uptake level in 99mTc-DPD scintigraphy and cardiac symptoms or cardiac function evaluated through transthoracic echocardiogram at the time of diagnosis. However, higher levels of cardiac uptake were associated with higher mortality in the follow-up period. This data suggests that 99mTc-DPD scintigraphy should be performed not only for diagnosis but also for prognosis assessment in these patients.

P1313 A curious case of endocarditis

INTRODUCTION

Nonbacterial thrombotic endocarditis (NBTE) is a rare form ofnoninfectious endocarditis in which a small sterile vegetations deposited on the heart valves (mostly aortic and mitral).It has been reported in every age group, most commonly affecting patients between the fourth and eighth decades of life with no sex predilection. Patients with advanced malignancy and those with systemic lupus erythematosus are the most common populations affected by NBTE, and they are typically asymptomatic until embolization occurs. Here, we report a case of a female patient with rheumatoid arthritis whose diagnosis was made prior to any thromboembolic event.

CASE REPORT DESCRIPTION

An 83-year-old female patient with a 10-year history of rheumatoid arthritis, was admitted for urinary tract infection with exacerbation of chronic renal disease and decompensated heart failure of unknown etiology. On physical examination, she was febrile (38,3ºC) with a blood pressure of 130/70 and pulse rate of 90 beats/min. Cardiac auscultation revealed a sistolic murmur of grade 1/4 in the fifth left intercostal space. A joint deformities in the hands were noted, such as interosseous atrophy and ulnar deviation. To evaluate this new sistolic murmur,the transthoracic echocardiogramwas performed and showed a vegetation in the mitral valve. Then, a transesophageal echocardiogram(TEE) was requested to better characterize this vegetation, showing a vegetation of 19x4mm involving the posterior cusp of the mitral valve leaflet, with moderate mitral regurgitation,being the hypothesis of infective endocarditis (IE) proposed. There were no other significant abnormalities in the remaining echocardiogram. Empirical antibiotic therapy to IE was initiated. The TEE was repeated after 4 weeks of antibiotic therapy with maintenance of the referred vegetation and mention of a smaller one (10x2mm). Clinical investigation didn’t show any infectious process. Hence, the hypothesis of NBTE was established. Anti-coagulation therapy was started immediately. The NBTE lesion disappeared in the follow-up echocardiography three months post anti-coagulation treatment.

CONCLUSION

Although NBTE is an uncommon and difficult diagnosis that requires a high degree of suspicion, its timely diagnosis is essential since it allows the prevention of thromboembolic events, resulting in a positive impact on patients" quality of life. In addition, the existence of this clinical condition may allow the diagnosis of another underlying disease, such as a hidden neoplasia. Thus, the authors believe that the sharing of this clinical case will allow a reflection on this entity emphasizing the importance in the hypotheses of vegetation diagnosis. From the authors" knowledge, from the available medical literature, the clinical case presented is one of the few NBTEs described in patients with rheumatoid arthritis, with mitral valve involvement and whose diagnosis was made before any thromboembolic event.
