A Delphi consensus to identify the key screening tests/questions for a digital neurological examination for epidemiological research

BACKGROUND

Most neurological diseases have no curative treatment; therefore, focusing on prevention is key. Continuous research to uncover the protective and risk factors associated with different neurological diseases is crucial to successfully inform prevention strategies. eHealth has been showing promising advantages in healthcare and public health and may therefore be relevant to facilitate epidemiological studies.

OBJECTIVE

In this study, we performed a Delphi consensus exercise to identify the key screening tests to inform the development of a digital neurological examination tool for epidemiological research.

METHODS

Twelve panellists (six experts in neurological examination, five experts in data collection-two were also experts in the neurological examination, and three experts in participant experience) of different nationalities joined the Delphi exercise. Experts in the neurological examination provided a selection of items that allow ruling out neurological impairment and can be performed by trained health workers. The items were then rated by them and other experts in terms of their feasibility and acceptability.

RESULTS

Ten tests and seven anamnestic questions were included in the final set of screening items for the digital neurological examination. Three tests and five anamnestic questions were excluded from the final selection due to their low ratings on feasibility.

CONCLUSION

This work identifies the key feasible and acceptable screening tests and anamnestic questions to build an electronic tool for performing the neurological examination, in the absence of a neurologist.

Poster No. 040 Traversing boundaries inside the heart

An 84-year-old man with previous pulmonary embolism (PE) was admitted to hospital for acute dyspnea. He was normotensive, but tachypneic and tachycardic. Non-relevant findings on auscultation. ECG showed sinus tachycardia and blood tests depicted elevated D-dimers and troponin I. Angio-CT diagnosed a PE. Echocardiogram (echo) showed an enlarged right ventricle with depressed function, a flattened septum with paradoxical movement, preserved left ventricular function, no intracavitary masses. Enoxaparin was started. Days later he developed new left sided hemiparesis. Acute ischemic cerebral lesion on CT scan. Echo disclosed a new hyperechogenic highly mobile mass attached to the interatrial septum moving from the right to the left atrium, suggestive of thrombus. Anticoagulation was maintained and on new echo evaluation days later there were no intracardiac masses. Agitated saline echo testing disclosed the presence of a patent foramen ovale, supporting the previous notion that a thrombus was moving between interatrial chambers. Oncological screening and prothrombotic evaluation were not completed due to unfavorable clinical evolution.

Paradoxical embolism (PaE) is usually a presumptive diagnosis. It is rarely found in clinical practice, though its prevalence may be underestimated due to the transient nature of the phenomenon and the difficulty in identifying a venous thrombus-in-transit through a cardiac defect and subsequent arterial embolism. The presence of a thrombus-in-transit modifies the treatment strategy, requiring urgent management due to the impeding risk of PaE, with treatment options comprising anticoagulation, thrombolysis and thrombectomy. Although no consensus exists regarding optimal strategy, surgical embolectomy is the favored approach in most published cases.

Screening Accuracy of the Portuguese version of the Postpartum Depression Screening Scale-7 according to DSM-5 criteria

Introduction

The Portuguese shortest version of the Perinatal Depression Screening Scale/PDSS-7 proved to be valid and reliable, in Portugal and Brazil, but it is essential to analyze its operational characteristics before using it for screening purposes.

Objectives

To determine PDSS-7 cut-off points and associated conditional probabilities to screen for major depression, according to the DSM-5.

Methods

he pregnancy sample was composed of 259 women in the second trimester (Mean gestation weeks=17.83±4.750). The postpartum sample consisted of 241 women assessed between the 2^nd-6^thmonths postpartum(M=17.99±4.689 weeks postpartum). All women completed the PDSS-7 and were interviewed with the Diagnostic Interview for Psychological Distress(Pereira et al., 2017), a semi-structured clinical interview to assess the most prevalent psychiatric disorders in the perinatal period according to the DSM-5 criteria. MedCalc was used to perform ROC analysis.

Results

During pregnancy, the major depression prevalence was of 4.6%(n=12). The cut-off point that maximizes the Youden Index(J=.98, 95%CI: .97-.99; AUC=.99; se=.004; p<.001) was of 18(95%CI:17-19), which resulted in a sensitivity of 100%(71.5%-100%), a specificity of 97.98%(95.3%-99.3%), a positive predictive value/+PP of 68.8%(48.0%-84.0%) and a negative predictive value/-PP of 100%. In the postpartum, the major depression prevalence was of 10.4%(n=25). The cut-off point(J=.79, 95%CI: .63-.82; AUC=.89; se=.036; p<.001) was of 14(95%CI: 12-16), with a sensitivity of 85.0%(69.3%-93.2%), a specificity of 85.0%(69.3%-93.2%), a +PP of 56.5%(46.1%-67.3%) and a -PP of 97.5%(94.6%-98.8%).

Conclusions

The Portuguese version of PDSS-7 presents good combinations of sensitivity and specificity, being accurate and usable to screen for depression during pregnancy and in the postpartum both in research and primary health care.

Further Validation of the Short Form of the Self-Compassion Scale in a sample of Portuguese Medicine Students

Introduction

The Short Form of the Self-Compassion Scale (SCS-SF; Raes et al. 2011) is composed of 12 items that evaluate the same six dimensions (Self-Kindness/SK, Self-Judgement/SJ, Common Humanity/CH, Isolation, Mindfulness/M, Over-Identification/OI) as the long scale (26 items). The Portuguese version of the SCS-SF (Castilho et al. 2015) was validated in a vast sample from clinical and general populations, the latter being composed of students, other than from medicine courses.

Objectives

To analyze the psychometric properties of the Portuguese version of the SCS-SF in a sample of Medicine/Dentistry students.

Methods

Participants were 666 Portuguese medicine (82.6%) and dentistry (17.4%) students (81.8% girls); they answered an online survey including the SCS and other validated questionnaires from the OECD Study on Social and Emotional Skills/SSES: Stress resistance, Emotional control, Optimism and Persistence.

Results

Confirmatory Factor Analysis showed that the model composed of six factors, two second order factors (positive and negative) and one third order factor (total) presented good fit indexes (χ2/df=3.013; RMSEA=.0066, p<.001; CFI=.970; TLI=.948, GFI=.947). The Cronbach’s alfas were .892, .869 and .877 respectively for the total, self-compassion and self-criticism dimension. Pearson correlations of the SCS-SF total score, self-compassion and self-criticism dimensional scores were moderate to high with the SSES measures, from .272/-.236/.247 with Persistence to .709/-.634/.615 with Optimism.

Conclusions

Although reduced to less than half than the original SCS, the SCS–SF is a valid and useful alternative to measure general self-compassion and their positive and negative components in an ongoing longitudinal research with medicine/dentistry students.

Grief during the COVID-19 pandemic: A cross-sectional online survey in university students

Introduction

Almost 5 million people worldwide have lost their lives due to SARS-CoV-2 (source: WHO coronavirus (COVID-19) dashboard, data of 1.10.2021; https://covid19.who.int/) and therefore, globally, there is an increase of people in grief due to the death of a significant other.

Objectives

To study psychological correlates of grief during the COVID-19 pandemic.

Methods

591 university students, with a mean age of 23.84±7.95 years (range 18-65 years; 76.8% women; 91.2% Portuguese) completed an online questionnaire during the second COVID-19 confinement (from 15.02 to 13.03.2021), with sociodemographic questions, the Pandemic Stress Index, the Mental Health Inventory, Insomnia Scale, questions on physical/ psychological health, and social isolation.

Results

Students bereaving the death of a significant other (n=93, 15.7%; n=25, 26.9% reported cause was SARS-CoV-2; time since death: < 3 months to 1-year), compared to those who did not (n= 498; 84.3%), described poorer psychological health, higher psychological distress (depression, anxiety, lack of control) and sleep difficulties, higher levels of stress (higher impact of COVID pandemic in daily life, and higher behavior changes in response to COVID-19) and more social isolation.

Conclusions

COVID-19 pandemic-related stress is a source of additional stress for bereaved students. Grief is also associated with social isolation, poor mental health (depression, anxiety, lack of control) and sleep difficulties. Screening efforts, guidance, and counseling from professionals of mental health care, primary health care, and universities health care services during and after the COVID-19 pandemic could be extremely beneficial for bereaved students, particularly for those at higher risk of developing prolonged grief disorder.

Further validation of the European and Brazilian Portuguese short version of the Postpartum Depression Screening Scale-7

Introduction

We have recently validated the Portuguese shortest version of the Perinatal Depression Screening Scale-PDSS-7 (items selected from the PDSS-21; each one representing a dimension evaluated by the PDSS-35), for the assessment of depression severity in pregnancy, both in Portugal and Brazil.

Objectives

To analyze the validity and reliability of the PDSS-7 Portuguese version to evaluate postpartum women both from Portugal and Brazil.

Methods

The Portuguese sample was composed of 304 women between the 2nd-6th postpartum months (Mean=20.09±7.21 weeks postpartum). These participants were not the same who participated in the psychometric study that led to the selection of the seven items. The Brazilian sample was composed of 121 women (Mean=10.51±4.53 weeks postpartum). All the participants completed the European/Brazilian Portuguese versions of PDSS-21, which was composed of the same items and included the seven items of PDSS-7. Participants also filled in the validated versions of Perinatal Anxiety Screening Scale and Profile of Mood States.

Results

Confirmatory Factor Analysis revealed that the unidimensional model of PDSS-7 presented acceptable/good fit indexes in both samples (Portuguese/Brazilian: χ²/d.f.=2.6598/1.7897; RMSEA=.0740/.0807, CFI=.8289/.7934, TLI=.7901/.8434, GFI=.9298/.9496; p<.001). The PDSS-7 Cronbach’s alphas were of .841/.856 and all the items contributed to the internal consistency. Pearson correlations with postpartum anxiety (.646/.763) and negative affect (.666/.676) were significantly (p<.01) high. PDSS-7 mean scores were higher in the Brazilian sample (16.06±7.39 versus 11.37±4.37, p<.01).

Conclusions

PDSS-7 presented validity (construct and convergent), reliability and utility in clinical and research settings, including in transcultural studies, in Portugal and Brazil, namely in the postpartum.

Triple-Valve Infective Endocarditis: A Case with Unusual Features

Infective endocarditis is a condition associated with high morbidity and mortality, usually with univalvular involvement. We describe the case of a 76-year-old woman with triple-valve endocarditis due to Streptococcus gallolyticus, complicated by perivalvular suppurative lesions, acute heart failure and acute kidney injury. Unfortunately, the patient died despite antibiotic therapy and emergent surgery. This case highlights uncommon triple-valve involvement in the absence of risk factors, posing a diagnostic and therapeutic challenge.

Monitoring Adherence to Asthma Inhalers Using the InspirerMundi App: Analysis of Real-World, Medium-Term Feasibility Studies

Background: Poor medication adherence is a major challenge in asthma and objective assessment of inhaler adherence is needed. InspirerMundi app aims to monitor inhaler adherence while turning it into a positive experience through gamification and social support.

Objective: We assessed the medium-term feasibility of the InspirerMundi app to monitor inhaler adherence in real-world patients with persistent asthma (treated with daily inhaled medication). In addition, we attempted to identify the characteristics of the patients related to higher app use.

Methods: Two real-world multicenter observational studies, with one initial face-to-face visit and a 4-month telephone interview, were conducted in 29 secondary care centers from Portugal. During an initial face-to-face visit, patients were invited to use the app daily to register their asthma medication intakes. A scheduled intake was considered taken when patients took a photo of the medication (inhaler, blister, or others) using the image-based medication detection tool. Medication adherence was calculated as the number of doses taken as a percentage of the number scheduled. Interacting with the app ≥30 days was used as the cut-off for higher app use.

Results: A total of 114 patients {median 20 [percentile 25 to percentile 75 (P25–P75) 16–36] years, 62% adults} were invited, 107 (94%) installed the app and 83 (73%) completed the 4-month interview. Patients interacted with the app for a median of 18 [3–45] days, translated on a median use rate of 15 [3–38]%. Median inhaler adherence assessed through the app was 34 [4–73]% when considering all scheduled inhalations for the study period. Inhaler adherence assessed was not significantly correlated with self-reported estimates. Median adherence for oral and other medication was 41 [6–83]% and 43 [3–73]%, respectively. Patients with higher app use were slightly older (p = 0.012), more frequently taking medication for other health conditions (p = 0.040), and more frequently prescribed long-acting muscarinic antagonists (LAMA, p = 0.024). After 4 months, Control of Allergic Rhinitis and Asthma Test (CARAT) scores improved (p < 0.001), but no differences between patients interacting with the app for 30 days or less were seen.

Conclusions: The InspirerMundi app was feasible to monitor inhaler adherence in patients with persistent asthma. The persistent use of this mHealth technology varies widely. A better understanding of characteristics related to higher app use is still needed before effectiveness studies are undertaken.

The portuguese version of the big three perfectionism scale – further validation with adults from the general population

Introduction

Both original Big Three Perfectionism Scale (BTPS; Smith et al. 2016), and the Portuguese version validated with a sample of university students (Lino et al. 2018) evaluates three second-order factors (rigid, self-oriented and narcissistic perfectionism) and ten facets.

Objectives

To confirm the BTPS three-factors-ten-dimensions’ structure in a sample of Portuguese adults from the general population.

Methods

A sample of 467 adults (70.7% females; Mean age=38.44±12.27; range: 25-82) answered the BTPS Portuguese version and other validated perfectionism measures (Multidimensional Perfectionism Scales from Frost and Hewitt & Flett; Self-Presentation Perfectionism Scale). To study the temporal stability a sub-sample of 132 participants completed the BTPS again after approximately five weeks. SPSS and AMOS software was used.

Results

The second order model presented an acceptable fit (X²/df=3.115; TLI=.811; CFI=.825; RMSEA=.067). There was also evidence of a general factor comprising all the 45 items (X²/df=3.127; TLI=.809; CFI=.823; [JA1] RMSEA=.068). The Cronbach alphas of the three factors ranged from a=.88 to a=.92; and facets had a>.70 showing a total of a=.94. Total and dimensional scores showed significant positive and moderate to high correlations with the other perfectionism measures and their test-retest correlation coefficients were r=.85 (p<0.001).

Conclusions

This study confirms the validity and reliability of the Portuguese BTPS underlying three-factors structure. Additionally, we found, for the first time, that BTPS can also be validly and reliably used to measure a global perfectionism construct. It is our intention to develop a shorter version the Portuguese BTPS in the near future.

Assessment of Qigong Effects on Anxiety of High-school Students: A Randomized Controlled Trial

CONTEXT

Students are vulnerable to developing anxiety, a psychiatric disorder closely related to emotional stress, when systematically stressed by classes, homework, and evaluations. Qigong integrates physical, respiratory, and mental exercises, inducing vegetative biofeedback with significant effects on physiological regulation.

OBJECTIVE

The current study aimed to assess the potential effects of specific Qigong exercises on students' anxiety levels and evaluate the feasibility of practical integration in a daily school context.

DESIGN

The research team developed a randomized controlled trial.

SETTING

This study was performed in Cedros and Horizonte private schools located in Vila Nova de Gaia in Portugal.

PARTICIPANTS

Participants were 104 high-school students at the schools.

INTERVENTION

Participants were randomly divided into three groups: (1) an intervention group, the Qigong (QG) group (n = 34), which performed Qigong exercises; (2) a control group, the TV documentary (TVD) group (n = 34), which watched a TV documentary; and (3) a second control group, the typical school duties (TSD) group (n = 36), which performed regular school duties.

OUTCOME MEASURES

Anxiety levels were assessed through a psychological test, the State-Trait Anxiety Inventory (STAI) and salivary cortisol tests.

RESULTS

Psychological and biochemical variables assessed at baseline and postintervention showed a greater decrease in anxiety levels in the QG group than in the other two groups.

CONCLUSIONS

Qigong seems to be an efficient tool to reduce anxiety and control the stress of high-school students.

Feasibility and Acceptability of an Asthma App to Monitor Medication Adherence: Mixed Methods Study

BACKGROUND

Poor medication adherence is a major challenge in asthma, and objective assessment of inhaler adherence is needed. The InspirerMundi app aims to monitor adherence while providing a positive experience through gamification and social support.

OBJECTIVE

This study aimed to evaluate the feasibility and acceptability of the InspirerMundi app to monitor medication adherence in adolescents and adults with persistent asthma (treated with daily inhaled medication).

METHODS

A 1-month mixed method multicenter observational study was conducted in 26 secondary care centers from Portugal and Spain. During an initial face-to-face visit, physicians reported patients' asthma therapeutic plan in a structured questionnaire. During the visits, patients were invited to use the app daily to register their asthma medication intakes. A scheduled intake was considered taken when patients registered the intake (inhaler, blister, or other drug formulation) by using the image-based medication detection tool. At 1 month, patients were interviewed by phone, and app satisfaction was assessed on a 1 (low) to 5 (high) scale. Patients were also asked to point out the most and least preferred app features and make suggestions for future app improvements.

RESULTS

A total of 107 patients (median 27 [P25-P75 14-40] years) were invited, 92.5% (99/107) installed the app, and 73.8% (79/107) completed the 1-month interview. Patients interacted with the app a median of 9 (P25-P75 1-24) days. At least one medication was registered in the app by 78% (77/99) of patients. A total of 53% (52/99) of participants registered all prescribed inhalers, and 34% (34/99) registered the complete asthma therapeutic plan. Median medication adherence was 75% (P25-P75 25%-90%) for inhalers and 82% (P25-P75 50%-94%) for other drug formulations. Patients were globally satisfied with the app, with 75% (59/79) scoring ≥4,; adherence monitoring, symptom monitoring, and gamification features being the most highly scored components; and the medication detection tool among the lowest scored. A total of 53% (42/79) of the patients stated that the app had motivated them to improve adherence to inhaled medication and 77% (61/79) would recommend the app to other patients. Patient feedback was reflected in 4 major themes: medication-related features (67/79, 85%), gamification and social network (33/79, 42%), symptom monitoring and physician communication (21/79, 27%), and other aspects (16/79, 20%).

CONCLUSIONS

The InspirerMundi app was feasible and acceptable to monitor medication adherence in patients with asthma. Based on patient feedback and to increase the registering of medications, the therapeutic plan registration and medication detection tool were redesigned. Our results highlight the importance of patient participation to produce a patient-centered and engaging mHealth asthma app.

Antepartum depressive and anxious symptoms: Association with physiological parameters of the newborn

Introduction

The Perinatal period is a time of vulnerability for developing psychiatric disorders of higher prevalence in the female gender - depression and anxiety1. Numerous authors have proposed that maternal psychological factors could influence pregnancy course and the well-being of mother and newborn2.

Objectives

To explore the relationship between perinatal psychological disorder and physiological parameters evaluated at birth, such as the Apgar Index (AI; 1, 5 and 10 minutes), head circumference, weight, length and age.

Methods

533 women answered, in the second trimester of pregnancy (16.98±4.83 weeks of gestation), several questions about psychosocial variables, the Perinatal Depression Screening Scale3 and the Perinatal Anxiety Screening Scale4. Of these, 208 (39.0%) women were interviewed with the Diagnostic Interview for Psychological Distress5. Newborn physiological parameters were obtained from electronic health records.

Results

AI was significantly (p<.01) and moderately (r≈.25) correlated with maternal anxious symptomatology, and with the experience of a stressful event in the last year (only AI 1 minute). Newborns of women with clinically relevant anxious symptomatology (>cutoff point, 14.6%) had significantly lower AI (p<.05), which was also observed in newborns of women who considered having had a stressful event (only AI 1 minute). Women’s newborns with maternal anxiety disorders during pregnancy (5.3%), had significantly lower values in AI, head circumference, weight and age of birth. Regression analyses showed that anxiety in pregnancy (symptoms and/or diagnoses) is a predictor of newborn physiological parameters, explaining significant percentages(r≈22%; p<.05) of its variability.

Conclusions

Early detection of psychological disorders in pregnancy, namely anxiety, is determinant to prevent adverse neonatal outcomes.

Mindfulness and self-compassion based intervention program to prevent burnout in medical and dentistry students

Introduction

Burnout occurs in every stage of a medical graduation and career. In the first years of graduation, is affects 35-45% of medical and dentistry students. This has severe consequences, such as: higher levels of suicidal ideation, substance abuse, medical errors and medical neglect; lower levels of empathy and self-compassion - essential to the quality of healthcare. Students with certain personality traits (e.g., neuroticism and, particularly, perfectionism) are more vulnerable to emotional dysregulation when facing stressors of daily life. Our recent studies proved that mindfulness and self-compassion can attenuate the effect of perfectionism on psychological distress.

Objectives

To present the rational, materials, methodology and preliminary results of our project COMBURNOUT, aimed to develop, implement and assess the efficacy of a mindfulness and self-compassion-based intervention to prevent burnout in medical and dentistry students.

Methods

Students with high levels of burnout, psychological distress and perfectionism will be randomly assigned to intervention (8 weekly sessions) or control groups. The sessions will be composed by psychoeducation about burnout, mindfulness and self-compassion practices, within and between sessions. The follow up will include three assessment moments until a year after the intervention.

Results

We expect that the experimental group will present significantly lower levels of burnout, psychological distress and perfectionism, and higher levels of emotional regulation skills.

Conclusions

The facilitators training and the manualization are guaranties of standardization and sustainability. If the positive impact of COMBURNOUT is verified, we intend to provide the program to medical/dentistry students from all over the country.

Pertinence and development of cibd – clinical interview for bipolar disorder

Introduction

Bipolar disorder (BD) is frequently underdiagnosed and due to poor screening, the average time between onset of symptoms and diagnosis is more than 7-years (Mantere et al., 2004). Improper diagnosis has serious consequences in intervention (Ghaemi et al., 2001), and previous assessment instruments are now considered insufficient to detect intervention changes, and to provide a more functional and integrated view of BD.

Objectives

Our study aims to develop a new DSM-5 based Clinical Interview for Bipolar Disorder (CIBD), providing criteria to diagnose BD, but also the individual’s perceptions dealing with BD symptoms. This interview follows the same structure of CIPD (Martins et al., 2015), which has shown acceptability by the participants and experts.

Methods

CIBD was developed by a multidisciplinary team considering the DSM-5 criteria for Bipolar Disorders. There was a thorough research regarding assessment and evaluation of BD, and several suggestions from an international task force of specialist working with BD patients were considered, when writing the questions for the interview. A detailed description of CIBD development is presented. The authors of the interview have extended experience in the management and assessment of BD patients, and CIBD is now being assessed by a wider non-related panel, regarding pertinence and clarity.

Results

Preliminary assessment and qualitative feedback from participants that were interviewed is shown, with an overall positive feedback.

Conclusions

CIBD assesses both the diagnosis/presence of mood episodes (hypo/mania, and depressive) and symptoms’ psychosocial correlates. CIBD detects subtle changes caused by intervention adding a much needed recovery focused perspective.

Postpartum depression screening scale-7: A valid and reliable short version both for portugal and brasil

Introduction

Screening programs for perinatal depression are systematicly implemented in developed countries. To circumvent the most commonly pointed limitation by the primary healthcare professionals (the questionnaires length), we have developed shorter forms of the Beck and Gable Postpartum Depression Screening Scale-35. The shortest version consists of seven items, each one representing a dimension evaluated by the PDSS. This PDSS-7 demonstrated equal levels of reliability and validity as the 35-item PDSS with the advantage of being completed in as little as 1-2 minutes(Pereira et al. 2013).

Objectives

To analyze the construct validity of the PDSS-7 using Confirmatory Factor Analysis, to use both in Portugal and in Brazil.

Methods

The Portuguese sample was composed of 616 women (Mean age: 32.29±4.466; Mean gestation weeks=17.13±4.929). These participants were not the same who participated in the psychometric study that led to the selection of the seven items. The Brazilian sample was composed of 350 women (Mean age: 30.01±5.452; Mean gestation weeks=25.17±6.55). They all had uncomplicated pregnancies and completed the European/Brazilian Portuguese versions of PDSS-24 (Pereira et al. 2013/ Barros et al. 2021), which was composed of the same items and included the seven items that compose the PDSS-7.

Results

The unidimensional model of PDSS-7 presented a good fit in both samples (Portuguese/Brazilian: χ²/d.f.=3.439/2.653; RMSEA=.066/.069, CFI=.974/.981, TLI=.947/.957, GFI=.939/.957; p<.001). The PDSS-7 Cronbach’s alphas were .82/.83 and all the items contribute to the internal consistency.

Conclusions

The PDSS-7 is a valid and precise, economic, fast and easy screening instrument for perinatal depression, a major public health problem, both in Portugal and in Brazil.

The role of dysfunctional attitudes towards motherhood in postpartum depressive symptoms and disorder

Introduction

Postpartum depression (PPD) is the commonest postpartum psychiatric condition, with prevalence rates around 20%¹. PPD is associated with a range of adverse outcomes for both the mother and infant². Therefore, identifying modifiable risk factors for perinatal depression is an important public health issue³.

Objectives

To explore the role of dysfunctional attitudes towards motherhood in postpartum depressive symptoms and disorder.

Methods

247 women were evaluated in the third (12.08±4.25 weeks) and sixth months (31.52± 7.16 weeks) postpartum with the Attitudes Towards Motherhood Scale⁴, the Postpartum Depression Screening Scale⁵ and the Diagnostic Interview for Psychological Distress-Postpartum⁶. Correlation analysis was performed followed by linear/logistic regression analysis when the coefficients proved significant (p<.05), using SPSS.

Results

Dysfunctional beliefs towards motherhood concerning judgement by others and maternal responsibility positively correlated with depressive symptoms at the third (.528; .406) and the sixth months (.506; .492) postpartum. Those dysfunctional beliefs were predictors of depressive symptoms at the third (ß=.440; ß=.151) and sixth months (ß=.322; ß.241) explaining 29.4% and 30.2% of its variance, respectively. Having dysfunctional beliefs at the third month significantly increase the likelihood of being diagnosed with Major Depression (DSM5) both in the third (Wald=9.992, OR=1.169; Wald=16.729, OR=1.231) and sixth months (Wald=5.638, OR=1.203; Wald=7.638, OR=1.301) (all p<.01).

Conclusions

Cognitive distortions should be included in the assessment of risk factors for PPD. Early identification of women presenting motherhood-specific cognitive biases may be crucial for implementing preventive interventions favoring a more positive and healthier motherhood experience.

Levels of depressive and anxious symptoms of pregnant women before vs. during the COVID-19 pandemic

Introduction

The effects on the population’s mental health due to the rapid global spread of COVID-19 are even greater for specific groups such as pregnant women.

Objectives

To compare levels of depressive and anxiety symptoms of pregnant women before vs. during the COVID-19 pandemic and to analyze the role of COVID-19 fear in perinatal psychological disorder.

Methods

200 Brazilian women evaluated during the pandemic in May-June 2020 (Sample-1) with the Brazilian Covid-19 Fear Scale for the Perinatal Period (Barros et al. 2020) and Screening for Perinatal Depression and the Perinatal Anxiety Crawl Scale, both with α> .90. Sample-1 was compared with a sample of 300 Portuguese women; these responded to the same questionnaires, before the pandemic, in 2017 and 2018 (Sample-2).

Results

Sample-1 had significantly higher mean scores of depression (52.73 ± 20.26 vs. 35.87 ± 16.98, t = 10.77, p <.001) and anxiety (36.58 ± 18.23 vs. 18.50 ± 13.71, t = 11.94, p <.001) and correlated significantly (p <.05) and moderate (r.30) with the fear of COVID-19. Hierarchical regression analyzes showed that, even after controlling for the effect of risk factors for PPP (Pereira et al. 2020), fear of COVID-19 is a significant predictor of depressive symptomatology levels (increments of 2-5%) and anxious (10-15%) during the pandemic.

Conclusions

The Sample-1 being from a different country may be a confusing factor, however, the magnitude of differences in PPP levels and the relevant role of fear in COVID-19, alert us to be aware of perinatal mental health.

Psychosocial risk factors for dysfunctional beliefs towards motherhood

Introduction

Motherhood-related beliefs are characterized by themes of failure and maternal role idealization. Recent studies found that postpartum depression/PPD is both predicted and a predictor by/for dysfunctional beliefs/DB. Additionally, it is possible that when contextual factors (eg. lack of social support) are present, women may anticipate the parenting experience as being of isolation, which in turn can lead to more dysfunctional attitudes.

Objectives

To explore psychosocial risk factors for motherhood-DB.

Methods

233 women were evaluated in the second trimester (17.05±4.82 weeks) of pregnancy and in the third month (12.08±4.25 weeks) postpartum sociodemographically and psychosocially (years of education, previous children and social support) and the Portuguese validated self-report questionnaires to assess: perinatal depression; perinatal anxiety; perfectionism; negative affect; self-compassion; and repetitive negative thinking (all in T0). The Attitudes Towards Motherhood Scale was administered in the postpartum. When Pearson/Spearmen correlation coefficients proved significant (p<.05), linear/logistic (hierarchic) regression analysis were performed.

Results

Motherhood-DB correlated significantly with all the variables, except for years of education, Other-oriented-Perfectionism and Common-Humanity. Motherhood-DB were significantly higher in women without previous children (p<.05). The final regression model was statistically significant (p<.001) explaining 15% of the Motherhood-DB variance, with Socially-Prescribed-Perfectionism and social support being the only statistically significant predictors. Hierarchic regression showed that even after controlling for social support, SSP significantly incremented the variance in 9%.

Conclusions

Our results highlight the need for preventive approaches to help women understand the origins of their dysfunctional beliefs (perfectionism, the myths of perfect motherhood) and for the promotion of positive cognitions.

What if HCM Risk-SCD was assessed with CMR maximum LV wall thickness measurements?

Funding Acknowledgements

Type of funding sources: None.

Introduction

The HCM Risk-SCD estimates the risk of sudden cardiac death at 5 years in patients (pts) with hypertrophic cardiomyopathy (HCM). According to ESC Guidelines, in pts with a 5-year risk of SCD &lt;4%, an implantable cardioverter defibrillator (ICD) is generally not indicated, in pts with a risk of 4 to less than 6%, an ICD may be considered and in pts with a 5-year risk ≥6%, an ICD should be considered. The association between the degree of LVH and sudden cardiac death (SCD) has been based on measurements of maximum LVWT by echocardiography which is part of HCM Risk-SCD score. However, cardiac magnetic resonance (CMR) has shown a superior resolution in characterization of cardiac structures, with additional role in SCD risk stratification. Whether measurements of LVWT by echocardiography and CMR are interchangeable has been brought to question.

Purpose

  We sought to evaluate the incidence of discrepant measurements of maximal LVWT between echocardiography and CMR and determine its implication in HCM Risk-SCD score and ICD indication.

Methods

Unicentric, retrospective analysis of pts submitted to CMR who had HCM as definitive diagnosis, between 1/2013 and 9/2019. CMR and echocardiographic measures were compared, as well as HCM Risk-SCD score calculated with these values (maximum LVWT was the only variable that differed between measures). Subsequently, pts were divided in three groups according to HCM Risk-SCD score: pts with a 5-year risk of SCD &lt;4% (G1), risk of 4 to less than 6% (G2) and risk ≥6% (G3).

Results

Out of the 781 CMR studies evaluated, 59 pts were found to have HCM (7.6%) with mean age of 62 ± 11 years and female predominance (50.8%). 12 pts had obstructive phenotype (20.3%). Mean LVWT was 20.0 ± 4.6mm when measured by CMR and 18.8 ± 4.6mm by echo; when comparing the measures by echo with CMR, there was a positive correlation between them (p &lt; 0.001; r 0.719). Mean HCM Risk-SCD was 2.80 ± 1.51% when measured by CMR and 2.69 ± 1.53% by echo; there was a positive correlation between these measures too (p &lt; 0.001; r 0.963). Maximum LV thickness evaluated by CMR showed a positive correlation (p = 0.006, r 0.384) with the HCM risk-score assessed by CMR. Only 1 pt changed risk group with CMR measurement of maximum LVWT (from G1 to G2). Conclusion: In this cohort, there was a positive, linear relationship between maximum LVWT and HCM Risk-SCD score measured by CMR and echocardiogram. Only 1 pt changed risk stratification group (5-year risk of SCD &lt;4% to 4 to less than 6%).  Although CMR measurements, when interpreted correctly, are more precise compared with echocardiography, in this cohort there was no impact on the patient"s future clinical orientation regarding ICD implantation.

Confirmatory Factor Analysis of the Postpartum Depression Screening Scale-21 in a Sample of Portuguese Women

Introduction

The postpartum depression screening scale (PDSS; Beck & Gable, 2002) is a widely used measure to assess women's depressive symptoms after their children's birth. Pereira et al. adapted, validated and developed a short-version of PDSS for Portuguese women (PDSS-21).

Objective

To examine the factor structure of the PDSS–21, using confirmatory factor analysis (CFA) in a sample of Portuguese women in the postpartum period.

Methods

The sample was composed of 208 women (mean age = 32.72; SD = 4.49) who completed the PDSS–21 approximately at the 6th week postpartum. CFA was used to test the model suggested by prior exploratory factor analyses of PDSS–21. AMOS software was used.

Results

After two items were deleted and some errors were correlated, CFA indicated a good fit for the second-order factor (χ2/df = 1.793; CFI = 0.957; GFI = 0.889, rmsea = 0.062; P [rmsea ≤ 0.05] < 0.056). The 19–item PDSS showed excellent internal consistency (α = 0.92) and the four dimensions presented Cronbach's alphas ranging between good (α = 0.83) and excellent (α = 0.93).

Conclusions

These findings suggest that the 19–item PDSS obtained through CFA is a reliable and valid measure to assess depressive symptoms among women in the postpartum period.

Validation of the self-compassion scale in a community sample of Portuguese pregnant women

Introduction

In recent years, researchers and clinicians have shown an increasing interest in self-compassion. Indeed, several studies have suggested that self-compassion is a positive factor for mental and physical health. The Self-Compassion Scale (SCS; Neff, 2003) has been widely used to assess six dimensions of self-compassion (self-kindness, self-judgment, common humanity, isolation, mindfulness and over-identification) among diverse populations. Recently, it has also been used in perinatal samples but its psychometric properties in pregnant women is still unexplored.

Objective

This study aims was to investigate the reliability and the validity of the SCS using Confirmatory Factor Analysis in a sample of Portuguese pregnant women.

Methods

Participants were 417 pregnant women with a mean age of 33 years old (SD = 4.74) in their second trimester of pregnancy (M = 17.26, SD = 4.78, weeks of gestation). Participants completed the Portuguese version of the SCS while waiting for the routine prenatal consultation in Maternity Hospital, Portugal.

Results

A was tested and results showed that the six-factor model had a good fit to the data (TLI = 0.93, CFI = 0.94, RMSEA = 0.06). The total SCS presented a good internal reliability (α = 0.91) and their subscales showed Cronbach's alphas ranging between adequate (α = 0.77) and good (α = 0.87).

Conclusions

Overall, these findings suggest that the Portuguese version of the SCS is a valid and reliable measure to assess self-compassion among pregnant women. Thus, SCS could be useful in diverse settings in the perinatal period.

Self-Concealment Scale: Validation of two Portuguese versions

Introduction

Self-Concealment Scale (SCS) is composed of ten items to measure self-concealment, defined as a tendency to conceal from others personal information that one perceives as distressing or negative (Larson and Chastain, 1990).

Objective

To investigate the psychometric properties of the SCS-10 Portuguese version and of an adapted version containing two additional items specifically focused on self-concealment related do health problems (physical and psychological)–SCS-12.

Methods

The Portuguese version of the SCS-12 and other validated questionnaires designed to evaluate self-reported health, perfectionism and optimism-pessimism were administered to a convenience sample of 555 adults from the community (60.5% females; mean age = 43.49 ± 10.565).

Results

The SCS-10 and SCS-12 Cronbach's alphas were α < 0.80. In both versions, all the items contribute to the internal consistency. The factor analysis, following the Kaiser and the Cattel's Scree Plot criteria, revealed that SCS-10 is unidimensional and that SCS-12 reliably and validly evaluates two dimensions: F1 Keeping secrets (Explained variance = 48.60%; α = 0.816), F2 Personal concealment including health problems (9.65%; α = 0.797). The pattern of correlations of the SCS dimensional and total scores was as follow: negative low correlations with physical health (@−0.20), negative moderate correlations with psychological health (@–.30), moderate correlations with self-oriented perfectionism, social-prescribed perfectionism, pessimism (@0.25) and optimism (@−0.20).

Conclusions

The Portuguese versions of SCS have good reliability and validity (construct and convergent-divergent). The factorial structure partially overlaps with the original. SCS could be useful for research proposes, namely in an ongoing project on the role of the mentioned personality traits on illness and health behavior.

Comparison of peribulbar block and general anaesthesia in mechanical vitrectomy: a prospective observational study

INTRODUCTION

Vitrectomy surgery is a common procedure for the treatment of several types of ophthalmologic conditions. It can be performed under regional anaesthesia with peribulbar block (PB) or general anaesthesia (GA). There are no evidence-based recommendations on the optimal anaesthesia strategy for this procedure. The aim of this study was to compare the advantages of PB and GA for vitrectomy surgery.

MATERIALS AND METHODS

A prospective observational study was conducted on adults submitted for mechanical vitrectomy between January 2017 and December 2017. Demographic and perioperative data were collected, namely ASA physical status, median arterial pressure, heart rate, postoperative opioid consumption, postoperative nausea and vomiting, times of induction, surgery, recovery, and hospital stay and costs considering medication and material needed. Statistical analysis was performed using SPSS v.25, with chi-square, Fisher and Mann-Whitney U tests, according to the type of variables analysed.

RESULTS AND DISCUSSION

We included 179 patients submitted for mechanical vitrectomy: 91 (51%) with PB and 88 (49%) under GA. Patients submitted to PB were older (69.0 vs. 64.5 years, p=.006) and presented with higher ASA physical status (p=.001). For haemodynamic outcomes, patients submitted to PB presented with less variation of median arterial pressure (-3.0 vs. -13.5mmHg, p=.000) and with no significant differences in heart rate (-2.0 vs. -3.0 bpm, p=.825). In the postoperative period, the PB group presented with decreased need of postoperative analgesia (0.0 vs. 5.0, p=.026) and a lower incidence of nausea and vomiting (1.0 vs. 12.0, p=.001). Times related to anaesthesia and surgery were better in PB group, with shorter induction time (10.0 vs. 11.0min, p=.000), surgery time (56.5 vs. 62.0min, p=.001), recovery time (10.0 vs. 75.5min, p=.000), and hospital stay (2.0 vs. 3.0 days, p=.000). When analysing costs, PB was less expensive than GA (4.65 vs. 12.09 euros, p=.021) CONCLUSION: PB is a reliable and safe alternative to GA for patients undergoing mechanical vitrectomy, permitting good anaesthesia and akinesia conditions during surgery, better haemodynamic stability, and less postoperative complications, especially in older patients and those with more comorbidities.

P767 Imagiologic features and Prevalence of Cardiac Lesions detected in Transesophageal Echocardiography

INTRODUCTION

Echocardiography plays a central role in the detection of intracardiac lesions, with transesophageal echocardiography (TEE) acquiring an outstanding role due to its increased sensitivity, improving diagnosis and evaluation of complications.

PURPOSE

To characterize clinically and echocardiographically the type of intracardiac masses mostly identified on TEE, in order to reflect about its prevalence, exam indication and echocardiographic criteria for correct diagnosis.

METHODS

Unicentric, retrospective observational analysis of TEE examinations performed between 01/2014 and 05/2019. Data collected from TEE registers and patient process assessment. Cardiac findings were classified according to its echocardiographic features as vegetations, thrombi or suspected tumoral masses.

RESULTS

144 TEE examinations revealed the presence of intracavitary lesions, with 62% of them (89 exams) having imagiologic features suggestive of vegetations, with polypoid highly mobile lesions attached to valve leaflets, often leading to valvular insufficiency. More than one valve was affected in 21% and about 30% were prosthetic valves. Potential serious complications such as perforation and abscess formation were present in 13% and 7%, respectively.

35 examinations disclosed the presence of thrombi, 66% located on the left atrial appendage and 17% on the left atrium (LA). In 4 cases they were attached to prosthetic valves and 10 of the patients had not been anticoagulated previously. Some doubtful diagnosis were lately confirmed after disappearance of the lesion with anticoagulation therapy.

Diagnosis of tumoral masses was made in 11%, some of them waiting for histologic confirmation. 50% had features resembling pappilary fibroelastomas (PF) (38% of the aortic valve, 25% of the mitral valve, 1 of the pulmonary valve and 1 the left ventricle pathologically confirmed), such as a filiform highly mobile pedunculated structure attached to a valve leaflet. Heterogeneous masses suggestive of myxomas were identified in 35%, 80% located on the LA.

The most frequent reason for performing a TEE examination was a previous embolic event, a doubtful image on transthoracic echocardiogram or before electrical cardioversion.

Except for PF which were increasingly detected by echocardiography, the prevalence of thrombi or vegetations remained similar across the years.

Most presumptive diagnosis made by TEE were confirmed based on clinical evolution or histology.

CONCLUSIONS

In this cohort, most TEE examinations revealed the presence of vegetations, a major criterion for establishing the diagnosis of infective endocarditis.

TEE enables more accurate evaluation of the lesions and although histologic confirmation is frequently necessary, some imagiologic features allow for a presumptive diagnosis which is often correct.

This analysis also reflects the prevalence of cardiac lesions and the increased awareness of some conditions, such as PF.

P228 Mitral valve aneurysm in the context of post-infective endocarditis in hypertrophic cardiomyopathy: an issue of inflammation or pressure gradients?

Mitral valve aneurysms (MVA) are uncommon and usually develop acutely in the setting of infective endocarditis (IE).

We present a case report of a patient with a ruptured aneurysm of the mitral valve (MV) leaflet and obstructive hypertrophic cardiomyopathy (HCM), previously treated for IE. Echocardiography is essential for diagnosis, highlighting the importance of imaging for early identification and timely intervention.

CASE REPORT

68-year-old male patient with type 2 diabetes mellitus and dyslipidemia was admitted to hospital with a 3-week history of malaise, fever and recent left-sided abdominal pain. No past relevant history.

Physical examination revealed a grade II/VI systolic heart murmur at the cardiac apex, fever, abdominal tenderness in the left upper quadrant and purpuric lesions in the inferior limbs.

Neutrophilia, CPR 211mg/L. Positive blood cultures for Staphylococcus aureus methicillin-sensitive. Spleen embolization, with no abcess on abdominal CT.

Transthoracic (TTE) and transesophageal echocardiography (TEE) disclosed a highly mobile polypoid mass in the atrial side of the anterior MV leaflet, septal left ventricular hypertrophy and systolic anterior motion (SAM) of the MV. Mild mitral regurgitation (MR). No evidence of abcess, aneurysm or valve perforation.

The diagnosis of IE was established and the patient completed 42 days of Flucloxaciline. Favorable clinical evolution, residual lesions on the MV.

TTE and TEE were repeated on follow-up. Besides HCM and SAM of the MV, an aneurysm of the anterior leaflet of the MV was identified and two regurgitant jets: one due to incomplete coaptation of the leaflets; other through the perforated aneurysm. Mild global MR.

A strategy of close follow-up was adopted. Beta blocker dose was increased. Maintenance of the characteristics of the aneurysm.

DISCUSSION

MVA are rare, with perforation and significant MR development as the most serious complications.

They mostly develop in the acute setting of IE of the aortic valve (AV), due to the "jet lesion" from the regurgitant jet or direct extension of the infection. In this case, MVA developed as a late complication of IE of the MV.

Previous infection and inflammation lead to increased susceptibility of the valve leaflet, with possible persistent chronic inflammation. In the setting of obstructive HCM, the lesioned endothelium is exposed to significant intraventricular pressure gradients, which have probably raised its propensity to bulge towards the atrium, resulting in aneurysm formation and perforation.

Optimal approach to MVA has not been defined. If the setting of perforation with severe MR, surgery must be performed in order to avoid a fatal outcome. In small aneurysms with mild MR, a conservative approach seems reasonable.

The purpose of this case is to highlight potential complications of IE, which should be actively investigated, with echocardiography playing a central role in the diagnosis and follow-up.

Patient-physician discordance in assessment of adherence to inhaled controller medication: a cross-sectional analysis of two cohorts

OBJECTIVE

We aimed to compare patient's and physician's ratings of inhaled medication adherence and to identify predictors of patient-physician discordance.

DESIGN

Baseline data from two prospective multicentre observational studies.

SETTING

29 allergy, pulmonology and paediatric secondary care outpatient clinics in Portugal.

PARTICIPANTS

395 patients (≥13 years old) with persistent asthma.

MEASURES

Data on demographics, patient-physician relationship, upper airway control, asthma control, asthma treatment, forced expiratory volume in one second (FEV₁) and healthcare use were collected. Patients and physicians independently assessed adherence to inhaled controller medication during the previous week using a 100 mm Visual Analogue Scale (VAS). Discordance was defined as classification in distinct VAS categories (low 0-50; medium 51-80; high 81-100) or as an absolute difference in VAS scores ≥10 mm. Correlation between patients' and physicians' VAS scores/categories was explored. A multinomial logistic regression identified the predictors of physician overestimation and underestimation.

RESULTS

High inhaler adherence was reported both by patients (median (percentile 25 to percentile 75) 85 (65-95) mm; 53% VAS>80) and by physicians (84 (68-95) mm; 53% VAS>80). Correlation between patient and physician VAS scores was moderate (r_s=0.580; p<0.001). Discordance occurred in 56% of cases: in 28% physicians overestimated adherence and in 27% underestimated. Low adherence as assessed by the physician (OR=27.35 (9.85 to 75.95)), FEV₁ ≥80% (OR=2.59 (1.08 to 6.20)) and a first appointment (OR=5.63 (1.24 to 25.56)) were predictors of underestimation. An uncontrolled asthma (OR=2.33 (1.25 to 4.34)), uncontrolled upper airway disease (OR=2.86 (1.35 to 6.04)) and prescription of short-acting beta-agonists alone (OR=3.05 (1.15 to 8.08)) were associated with overestimation. Medium adherence as assessed by the physician was significantly associated with higher risk of discordance, both for overestimation and underestimation of adherence (OR=14.50 (6.04 to 34.81); OR=2.21 (1.07 to 4.58)), while having a written action plan decreased the likelihood of discordance (OR=0.25 (0.12 to 0.52); OR=0.41 (0.22 to 0.78)) (R²=44%).

CONCLUSION

Although both patients and physicians report high inhaler adherence, discordance occurred in half of cases. Implementation of objective adherence measures and effective communication are needed to improve patient-physician agreement.

Pru p 3 sublingual immunotherapy ultra-rush protocol is safe and clinically effective

Summary

Introduction. Sublingual immunotherapy (SLIT) with Pru p 3 can prevent severe allergic reactions to LTP-containing foods, but the standard initiation protocol is time-consuming. Objectives. Establish the safety of a novel ultra-rush initiation protocol for SLIT with Pru p 3. Methods. Prospective study comparing the side effects of the standard vs novel ultra-rush initiation protocols of SLIT with Pru p 3 in patients with anaphylaxis to LTP. Results. Fifteen patients were included (standard initiation, 5; ultra-rush initiation, 10), 80% females. All patients had oropharyngeal pruritus during initiation, 80% with spontaneous recovery, but no other gastro-intestinal, respiratory, cutaneous or systemic side effects occurred in any patient of both groups. Conclusion. The novel ultra-rush protocol halved the build-up time without increasing side effects.

Successful oral desensitization in children with cow's milk anaphylaxis: Clinical and laboratory evaluation up to nine-years follow-up

INTRODUCTION

Cow's milk protein allergy (CMPA) is the most common food allergy in children worldwide. Some children have severe and persistent CMPA, with near-fatal reactions after exposure to trace amounts of cow's milk-proteins (CMP). Strict avoidance diet is difficult, negatively affects quality of life and represents a conservative approach. Therefore, different therapeutic strategies are necessary.

OBJECTIVE

We aimed to assess long-term efficacy and safety of oral immunotherapy (OIT) in children with severe and long-lasting IgE-mediated CMPA.

MATERIALS AND METHODS

The authors present four case reports of patients with CMPA who underwent CMP-OIT, that have been under long-term follow-up up to nine years. We provide information about the clinical and laboratory evaluation. Skin prick tests (SPT), specific IgE and IgG4 were performed before, during, and after OIT. Immune profile after OIT was assessed by flow cytometry (lymphocyte subsets, regulatory T and B cells).

RESULTS

The success rate was 100%, and all patients currently have a free diet with minimal diary ingestion of 200mL CMP or equivalent. Specific IgE levels and SPT to CMP have progressively decreased, and specific IgG4 levels have increased. CD4⁺CD25⁺CD127^-/dim regulatory T cells were increased after OIT.

CONCLUSIONS

OIT ensured a clinical tolerance state after up to nine years, confirmed by both clinical and immune profile, allowing a diet without restrictions, with high satisfaction from patients and caregivers. We emphasize that OIT should be performed only by allergy experts in the hospital setting, and that only motivated families should be enrolled, since it is essential to ensure CMP daily intake at home.

Anaphylaxis to beta-lactam antibiotics at pediatric age: Six-year survey

INTRODUCTION

Beta-lactams are the most frequently used antibiotics in pediatric age. Anaphylactic reactions may occur and need to be properly studied, but studies in children are scarce.

OBJECTIVE

Characterization of case reports of anaphylaxis in children referred to an allergy department with suspected beta-lactams hypersensitivity.

MATERIALS AND METHODS

Retrospective analysis of all children referred to our Drug Allergy Center with suspected beta-lactams hypersensitivity between January 2011 and December 2016. Description of the drug allergy work-up performed studied according to standardized diagnostic procedures of ENDA/EAACI, including specific-IgE assay, skin prick and intradermal tests and diagnostic/alternative drug challenge tests.

RESULTS

146 children with suspected beta-lactams hypersensitivity were studied, and in 21 (14.4%) the diagnosis was confirmed. In all of them, except for three children, an alternative beta-lactam was found. In seven children (33.3% of those with confirmed beta-lactams hypersensitivity) anaphylaxis was confirmed, and all of them described reactions with cutaneous and respiratory or gastrointestinal involvement. The culprit drug was amoxicillin in six and flucloxacillin in one. In this sample, we also performed oral challenge with cefuroxime, being negative in all cases. Almost all cases of confirmed anaphylaxis (six from seven cases) were IgE mediated, with positive skin tests despite negative serum specific-IgE.

CONCLUSIONS

Allergic reactions to beta-lactams, although rare in children, require a detailed clinical history and a specialized drug allergy work-up to allow a correct diagnosis as well as to avoid the possibility of a potential life-threatening reaction and provide alternative drugs.

Pectoral nerve block as a single anesthetic technique for breast surgery and sentinel lymph node investigation

Breast cancer surgery is usually performed under general anesthesia or, more recently, combined with conventional regional techniques. Pectoral nerves (PECs) block appears as an analgesic alternative in these procedures, but few studies refer to it as a single anesthetic technique^1-3. In this case report, we describe a 56-year-old female patient, BMI 31kg/m², ASA IV, admitted for elective tumorectomy of the left upper quadrant of the breast and sentinel node investigation. Given the multiple comorbidities and the high anesthetic and surgical risk, the anaesthetic plan consisted in ultrasound guided PECs II block as a single anesthetic technique. The authors report a successful anesthetic and pain management without complications in breast surgery. PECs block, as a single anesthetic technique, may be safe, advantageous and effective with haemodynamic stability and few side effects in high risk cardiac patients.

Quality of recovery after surgery for cancer treatment

INTRODUCTION

Assessment of quality of recovery is important as an end-point for outcome research. This study aims to determine the incidence and determinants of poor quality of recovery (PQR) after surgery in patients scheduled for curative neoplastic surgery.

MATERIALS AND METHODS

An observational prospective study was performed in consecutive patients undergoing surgery for cancer treatment. The Quality of Recovery 15 score (QoR-15) was applied on the day before surgery (T0) and 24h after (T1). PQR was defined for patients with a QoR-15 score lower than the mean QoR-15 score at T1 minus one standard deviation. Preoperative quality of life was assessed with EuroQol-5D. Frailty and disability were defined using Clinical Frailty Scale and World Health Organization Disability Assessment Schedule 2.0.

RESULTS

One hundred and thirty-eight patients were enrolled and 31 (15.9%) were identified as having PQR. At T0, patients with PQR presented lower scores on total QoR-15 (P=.03) and had more problems on EuroQol-5D in mobility (P=.014), self-care (P=.027) and usual activities domains (P=.019). The difference of QoR-15 score between T1 and T0 was higher in PQR patients (P<.001). PQR had more frequently Revised Cardiac Risk Index (RCRI)≥2 (P=.012) and were more frequently frail (P=.03). PQR patients stayed longer in the hospital (P=.034).

CONCLUSION

PQR patients had lower QoR-15 before surgery, poor quality of life, were more frequently frail and had high cardiac risk factors. PQR patients stayed longer in the hospital.

Abstract P4-02-09: Breast cancer and magnetic resonance imaging (MRI): Background parenchymal enhancement (BPE) predicting response to neoadjuvant chemotherapy (NAC)

Objective: To assess the association of MRI BPE and pathological response in women diagnosed with stage II/III breast cancer submitted to NAC. Methods: This observational and cross-sectional retrospective study was performed in consecutive women who underwent NAC and had MRI exams before and after chemotherapy. The MRI was done before and after 2 weeks of completing NAC. BPE was classified according to ACR-BIRADS 5th edition. The type of BPE before NAC, its changes and the relationship to total pathologic complete response (TpCR) were evaluated. Data were paired with patient age, size on MRI before and after NAC, features of clinical response according to the RECIST criteria, tumor grade and immunohistochemical (IHC) subtypes. MRI assessment included amount of fibroglandular tissue, symmetry of BPE and measurement of tumor at the longest diameter. All images were blinded reviewed by a radiologist. We used for the changes of the BPE the Bowker symmetry test or the McNemar test and to analyze the factors related to the clinical and pathologic responses, logistic regression analysis. The level of significance adopted was 5% (p&lt;0.05). Results: We studied 71 women between 2009 and 2016. The medium age was 37 years old. BPE was symmetrical in 68 women (95.8%). Moderate and marked BPE was present in 28 (39.4%) of the affected breasts and in 25 (34.2%) of the contralateral breasts. After NAC all BPE were symmetrical and just 3% of them were moderate or marked. Regarding the IHC subtype, 40 women (56.3%) were triple negative or HER2 positive, and these women had a higher frequency of TpCR (55% for each, compared to 12.9% in patients with luminal subtypes). We found to be independently associated with pCR: the reduction of BPE (in the affected or contralateral breast) and the molecular subtypes triple negative and HER2 positive

Modulation of hepatic glutathione transferases isoenzymes in three bivalve species exposed to purified microcystin-LR and Microcystis extracts

This study compares the role of hepatic cytosolic glutathione transferases (cGST) isoforms of three different bivalve species to a Microcystis aeruginosa extract and purified MC-LR exposure (both at 150 μg MC-LR L^-1) for 24 h. Characterization and alterations of the cytosolic GST activities in Mytilus galloprovincialis, Ruditapes philippinarum and Corbicula fluminea were measured using four class-specific substrates and changes in individual GST isoforms expression were achieved by a subsequent two-dimensional electrophoresis analysis. Evaluation of cGST activity basal levels using the four class-specific substrates denoted quantitative differences between the three bivalves. Purified MC-LR did not induce any significant response from bivalves. On the other hand, cell extracts caused significant alterations according to bivalves and substrates. Among the three bivalves, only R. philippinarum showed a significant induction of cGST activity using generic 1-chloro-2,4-dinitrobenzene (CDNB) substrate. However, no significant alterations were detected in these clams by cell extracts using the other specific substrates. In contrast, C. fluminea revealed significant induction of cGST activity when using 3,4-dichloronitrobenzene (DCNB) and ethacrynic acid (EA). In M. galloprovincialis, cell extracts promoted a significant decrease of cGST activity when using EA substrate. Altered protein expression was quantitatively detected upon exposure to cell extracts for one spot in R. philippinarum and another for C. fluminea, both upregulated (2.0 and 8.5-fold, respectively) and identified as a sigma1-class GST in the case of the first. The results showed that the three bivalves presented specific adaptive biotransformation responses to MCs and other cyanobacteria compounds supported by the modulation of distinct cGST classes.

Confirmatory factor analysis of the perinatal depression screening scale-24

Introduction

Pereira et al. (2013) adapted to the antenatal period and validated a shorter version of the original 35-items Postpartum Depression Screening Scale (PDSS [1]), composed of 24 items, selected from the exploratory factor analysis matrix. In their study, the researchers considered this version a useful alternative to evaluate depressive symptoms in pregnancy, taking into account its reliability, concurrent validity and satisfactory combinations of sensitivity and specificity to screen for antenatal depression.

Aim

To confirm the four dimensions’ structure of the PDSS-24 using confirmatory factor analysis.

Methods

616 women (mean age: 32.29 ± 4.466) in the second trimester of pregnancy (mean weeks of gestation = 17.13 ± 4.929), with uncomplicated pregnancies, completed the PDSS-24 while waiting for their routine prenatal consultation at local health medical centers.

Results

The 4-dimensional model of PDSS-24 presented good fit (χ2[242] = 893,275; RMSEA = 0.067, CFI = 0.934, TLI = 0.94, PGFI = 0.717; P<.001). The PDSS-24 Cronbach's alpha was α=0.90; all factors presented good/excellent reliability: Derealization and failure (a = 0.87); Concentration difficulties and anxiety (a = 0.81), Suicidal ideation (a = 0.94), and sleeping difficulties (a = 0.89).

Conclusion

This further validation study emphasizes that PDSS-24 in an adequate measure of antenatal depressive symptoms. To better distinguish it from the version to use in the postpartum (PDSS-21 [2]), from now on, we will denominate it perinatal depression screening scale-24.

Confirmatory Factor Analysis of NEO-FFI-20 in a Portuguese Sample

Introduction

The Five-Factor Model organizes human personality traits under a comprehensive framework of five dimensions–neuroticism, extraversion, openness to experience, agreeableness and conscientiousness. The dimensions are empirical generalizations of enduring differences in behavioural, emotional and cognitive patterns between individuals. The Portuguese version of the NEO-Five Factor Inventory (NEO-FFI-20) is increasingly used as it is the shortest version to evaluate the “Big 5”.

Objective

To investigate the reliability and the validity of the Portuguese version of NEO-FFI-20-item (Bertoquini & Pais Ribeiro) in a Portuguese sample, using exploratory and confirmatory factor analysis (EFA and CFA).

Methods

747 participants [417 (55.8%) women; mean age = 42.13 ± 12.349 years] answered an online survey which included the NEO-FFI-20 and socio-demographic questions. The total sample was randomly divided in two sub-samples (sample A, n = 373; sample B, n = 374). Sample A was used to EFA and sample B was used to CFA.

Results

The Portuguese version of NEO-FFI-20, excluding items 14 and 16, had an acceptable fit to the data (χ2/df = 2.28; TLI = .88; CFI = .90; RMSEA = .06; P = .059). The internal consistency analysis resulted in: Neuroticism, α = .68; Extraversion, α = .62; Openness to Experience, α = .74; Agreeableness, α = .70; and Conscientiousness, α = .74.

Conclusions

The NEO-FFI-20 can be used to reliably and validly evaluate the BIG FIVE in an ongoing research project on traffic psychology to better understand and respond to risky behaviours on the road.
