Maternal distress during the COVID-19 outbreak: A socio-ecological perspective

INTRODUCTION

Mothers faced an increased risk of adverse mental health outcomes during the COVID-19 pandemic compared to other populations. However, there is little data on the factors that placed mothers at increased risk of distress.

AIMS

The present study explored a range of individual, familial, and environmental factors associated with psychological distress in mothers during the COVID-19 pandemic.

METHOD

This repeated cross-sectional study was composed of a convenience sample of mothers who completed an online survey that included a demographic questionnaire, an emotion regulation questionnaire, and the Depression, Anxiety, and Stress scale. The survey was administered during the second and third lockdowns in Israel in 2020-2021.

RESULTS

The study included 575 mothers (M age = 39). The findings of a hierarchical regression indicated that individual-level factors, composed of age and emotion regulation tendencies predicted psychological distress. The family-level factors of household income and number of children in the family also predicted distress. In terms of environmental-level factors, COVID-19-related media consumption and school status (open or closed) were also significant predictors of psychological distress. Importantly, the results showed that the most important predictors of psychological distress in mothers during the COVID-19 outbreak were school closures, household income, and the use of adaptive and maladaptive emotion regulation strategies.

CONCLUSIONS

The findings highlight the intersection of individual, familial, and environmental factors in mothers' mental health during crises.

Negative and positive interpretations of emotionally neutral situations modulate the desire to eat personally craved foods

Emotions play an important role in modulating food craving. Previous studies demonstrated that exposure to negative or positive stimuli can subsequently influence the desire to eat. However, in many daily situations, individuals self-generate their emotions, for example, by interpreting emotionally-neutral situations as positive or negative. So far, no studies have examined if and how positive and negative interpretations of emotionally-neutral situations modulate food craving. In this study, 65 healthy participants were asked to interpret emotionally-neutral images negatively or positively or observe the images naturally. Subsequently, participants rated their state negative/positive affect and their desire to eat their personally craved foods. The results demonstrate a lower desire to eat craved foods after negative interpretations and a higher desire to eat after positive interpretations, compared to an observe-naturally condition. Additionally, the impact of emotional interpretations on the desire to eat was mediated by participants' state negative/positive affect. These findings suggest that self-generated emotion as a result of negative/positive interpretations plays a significant role in modulating food craving. The results highlight the potential of modifying affective interpretations for the treatment of disorders that are characterized by both dysregulated food craving and emotion.

Boosting affective control with bifrontal transcranial direct current stimulation (tDCS): a proof-of-concept study in healthy individuals

Affective control refers to the ability to regulate emotions and is considered a marker of mental health. Transcranial direct current stimulation (tDCS), a non-invasive brain stimulation technique, holds promise to enhance affective control. In this between-subjects study in healthy individuals, we investigated the effects of bifrontal tDCS on core processes and higher-level markers of affective control. As such, we assessed direct tDCS effects on emotional interference during an affective control task and indirect effects on an instructed reappraisal task afterward. Results showed that the affective control task combined with active tDCS, compared to sham, resulted in enhanced cognitive emotion regulation. Specifically, participants in the active tDCS condition showed an increased propensity to use reappraisal and were more successful in doing so. Moreover, there was reduced vagally mediated heart rate variability indicative of attenuated emotion and self-regulation, in the sham, but not in the active condition. Surprisingly, there were no effects of tDCS on emotional interference during the affective control task, with Bayesian analyses showing extreme evidence against these effects. Nevertheless, there was a positive association between the emotional interference during the affective control task and participants' reappraisal success afterward for the active, but not the sham tDCS condition. The study offers valuable insights to guide future work on combined tDCS with affective control tasks or training on the ability to regulate emotions.

The role of the dentist and the orthodontist in early diagnosis of Gorlin-Goltz syndrome: a cephalometric and photometric study

AIM

The aim of this study was to analyse the facial characteristics and the craniofacial morphology in GGS patients in order to enable an early diagnosis.

BACKGROUND

Gorlin-Goltz syndrome (GGS) is a autosomic dominant disease, characterised by basal cell carcinoma, palmar/plantar pits, maxillary and mandibular keratocysts and dental abnormalities.

METHODS

Nine out of a sample of 24 GGS patients had complete cephalometric and photographic records at an average age of 8.7 years. Cephalometric and photometric analysis were carried out with standard analyses and compared with healthy patients matched for sex and age.

CONCLUSION

Early diagnosis of GGS based on clinical features could be useful to identify the presence of keratocysts through x-ray examination proceeding with surgical removal at an early stage, limiting space occupying damages.

The Psychological Science Accelerator's COVID-19 rapid-response dataset

In response to the COVID-19 pandemic, the Psychological Science Accelerator coordinated three large-scale psychological studies to examine the effects of loss-gain framing, cognitive reappraisals, and autonomy framing manipulations on behavioral intentions and affective measures. The data collected (April to October 2020) included specific measures for each experimental study, a general questionnaire examining health prevention behaviors and COVID-19 experience, geographical and cultural context characterization, and demographic information for each participant. Each participant started the study with the same general questions and then was randomized to complete either one longer experiment or two shorter experiments. Data were provided by 73,223 participants with varying completion rates. Participants completed the survey from 111 geopolitical regions in 44 unique languages/dialects. The anonymized dataset described here is provided in both raw and processed formats to facilitate re-use and further analyses. The dataset offers secondary analytic opportunities to explore coping, framing, and self-determination across a diverse, global sample obtained at the onset of the COVID-19 pandemic, which can be merged with other time-sampled or geographic data.

Working in corona-designated departments in a fortified underground hospital: Concerns about corona and predictors of job burnout

Background

In August 2020 during Israel's second COVID-19 wave Rambam Medical Center opened the Sammy Ofer Fortified Underground Emergency Hospital. This was declared a regional Corona center in the north of Israel, receiving the most severe Corona patients from the region. Alongside the advanced inpatient capacity and technology within the underground facility, there was a severe shortage of trained medical and paramedical staff, as well as harsh working conditions. The current study examined the implications and effects of working in an underground facility on healthcare workers, focusing on emotion regulation tendencies and profession as predictors of job burnout.

Methods

Seventy-six healthcare workers, who had worked in the underground hospital for a minimum continuous period of 2 weeks during the peak of the COVID-19 pandemic, and a control group of 40 healthcare workers from northern Israel were asked to fill out an online survey administered via Qualtrics (total sample 116). The survey comprised six questionnaires: a demographic survey questionnaire; a COVID-19 concerns questionnaire; a psychological distress questionnaire (DASS, Depression Anxiety Stress Scale); trait worry (PSWQ; Penn State Worry Questionnaire); emotion regulation (ERQ, Emotion Regulation Questionnaire), and burnout (SMBM, Shirom - Melamed Burnout Measure).

Results

Independent-samples t-tests revealed no significant differences in psychological distress or burnout between Rambam Underground hospital workers and the control group. Conversely, COVID-19 concern scores were significantly different in the two groups, the Rambam hospital workers showing less concern (M = 2.9, SD = 0.73) than the control group (M = 3.47, SD = 0.76) [t ₍₁₁₄₎ = -3.974, p < 0.001]. Hierarchical linear regression analysis identified the significant predictors of burnout among healthcare workers. Participants' profession (physician), psychological distress (total DASS score), and a personality trait of worry were statistically significant predictors for job burnout (p = 0.028, p < 0.001, p = 0.023, respectively). Concerns about COVID-19 marginally predicted job burnout (p = 0.09). Group (underground vs. control) and emotion regulation tendencies did not predict burnout.

Conclusion

The two groups showed no significant differences in psychological distress nor in burnout. Being a physician, having an intrinsic trait of being overly worried and experiencing psychological distress were significant predictors for job burnout among healthcare workers, regardless of work environment (underground vs. control).

Understanding the benefits of extrinsic emotion regulation in depression

Depression is a serious psychiatric illness that negatively affects people's feelings, thoughts, and actions. Providing emotion regulation support to others, also termed Extrinsic Emotion Regulation (EER), reduces depressive symptoms such as perseverative thinking and negative mood. In this conceptual review paper, we argue that EER may be especially beneficial for individuals with depression because it enhances the cognitive and affective processes known to be impaired in depression. Behavioral studies have shown that EER recruits processes related to cognitive empathy, intrinsic emotion regulation (IER), and reward, all impaired in depression. Neuroimaging data support these findings by showing that EER recruits brain regions related to these three processes, such as the ventrolateral prefrontal cortex which is associated with IER, the ventral striatum, which is associated with reward-related processes, and medial frontal regions related to cognitive empathy. This conceptual review paper sheds light on the mechanisms underlying the effectiveness of EER for individuals with depression and therefore offers novel avenues for treatment.

The link between emotion regulation and size estimation of spiders pictures among women with fear of spiders

Introduction

Fear is associated with perceptual biases. People who are afraid of spiders perceive spiders as larger than people without this fear. It is yet unclear, however, whether this effect can be influenced by using implicit (non-deliberate) emotion regulation (ER) processes and explicit (deliberate) ER strategies, such as reappraisal and suppression.

Method

This study examined the link between implicit and explicit ER and size estimation among women afraid of spiders. After performing an implicit ER (cognitive control) task, participants rated the size and valence of spiders, wasps and butterflies shown in pictures. Participants' tendency to use reappraisal and suppression was assessed using the Emotion Regulation Questionnaire.

Results

Results showed no effect of implicit ER on size and valence ratings. A greater tendency to use reappraisal was linked to reduced negative feelings on seeing the pictures of spiders. Greater use of suppression, however, was linked to increased size estimation of the spider stimuli.

Discussion

These results highlight the role of ER in perceptual biases and offer avenues for future ER-based treatments for specific phobias.

Cognitive Reappraisal Reduces the Influence of Threat on Food Craving

Cognitive reappraisal is perhaps the most researched emotion regulation strategy. It involves reinterpreting emotional content to reduce its impact. While many studies have demonstrated that cognitive reappraisal reduces negative affect, the utility of cognitive reappraisal in buffering against the consequences of negative affect on subsequent behaviors and attitudes is not clear. To address this issue, the present study assessed whether cognitive reappraisal mitigates the influence of immediate threat on food craving. In Experiment 1, 80 women performed a novel combination of a cognitive reappraisal task with a food-rating task. Participants were exposed to threat-provoking or neutral images and were instructed to either reappraise or observe the images. Subsequently, they rated their desire to eat different types of foods. As expected, the desire to eat decreased after exposure to threat-provoking content. However, after reappraising the threat-provoking images, the desire to eat increased relative to when participants merely observed these images. These results were replicated in Experiment 2 (N = 46) which also showed that the effect of reappraisal on the desire to eat was fully mediated by the subjective emotional reactions to the threat-provoking content. These findings show that cognitive reappraisal can modulate links between emotion and food craving by buffering against the consequences of negative affect on basic human processes.

Autonomous control for miniaturized mobile robots in unknown pipe networks

Despite recent advances in robotic technology, sewer pipe inspection is still limited to conventional approaches that use cable-tethered robots. Such commercially available tethered robots lack autonomy, and their operation must be manually controlled via their tethered cables. Consequently, they can only travel to a certain distance in pipe, cannot access small-diameter pipes, and their deployment incurs high costs for highly skilled operators. In this paper, we introduce a miniaturised mobile robot for pipe inspection. We present an autonomous control strategy for this robot that is effective, stable, and requires only low-computational resources. The robots used here can access pipes as small as 75 mm in diameter. Due to their small size, low carrying capacity, and limited battery supply, our robots can only carry simple sensors, a small processor, and miniature wheel-legs for locomotion. Yet, our control method is able to compensate for these limitations. We demonstrate fully autonomous robot mobility in a sewer pipe network, without any visual aid or power-hungry image processing. The control algorithm allows the robot to correctly recognise each local network configuration, and to make appropriate decisions accordingly. The control strategy was tested using the physical micro robot in a laboratory pipe network. In both simulation and experiment, the robot autonomously and exhaustively explored an unknown pipe network without missing any pipe section while avoiding obstacles. This is a significant advance towards fully autonomous inspection robot systems for sewer pipe networks.

Interstitial Duplication on Chromosome 3p14.3p13 in an Adolescent with Dysmorphic Features and Autism, Case Report

Introduction/Objective

The genetic etiology of autism spectrum disorders is only partially understood. Here we describe a 16-year-old male diagnosed with autism at two years of age. He has dysmorphic features, severe cognitive disability, and history of cryptorchidism. A review of systems was significant for slightly coarse features overall, with deep-set eyes, pinched nasal bridge with wide nasal tip, and widely spaced teeth. A large pectus excavatum deformity was also noted. Although the parent’s genetic testing concluded that this likely represents de novo mutation, it is worth mentioning that our patient has a 13-year-old female maternal first cousin with learning difficulties that were said to be less severe. There is no other family history of autism.

Methods/Case Report

Chromosome analysis showed an abnormal karyotype identifying a duplication of the short arm of chromosome 3 from p13 to p14.3, 46,XY,dup(3)(p13p14.3). Additional microarray testing confirmed this duplication and defined the size as 14.9 Mb. Regions of homozygosity of 29.8 Mb were also identified, representing about 1% of the autosomal genome. The duplicated area includes over 70 genes, thirteen of which are known Mendelian disease genes (IL17RD, HESX1, APPL1, FLNB, DNASEIL3, PDHB, ACOX2, ATXN7, SLC25A26, EOGT, LMOD3, MITF, and FOXP1). Duplications of 3p are extremely rare and can be de novo or inherited from a parent with a balanced translocation. Individuals with these better-described chromosome 3p duplications typically present with intellectual and developmental disabilities, such as autism, as 3p duplications typically present with intellectual and developmental disabilities, such as autism and distinctive dysmorphic features. This duplication has never been reported as a known syndrome and has minimal overlap with copy number variants (CNVs) among healthy individuals.

Results (if a Case Study enter NA)

NA

Conclusion

Autism spectrum disorders are largely characterized by speech, communication, and social impairment of varying degrees. Diagnosis is typically made on clinical grounds, but in 14-35% of cases, a genetic basis for the disorder, typically either due to a single gene disorder or a chromosomal deletion/duplication, may be found. This case report describes a rare finding of a 14.9 Mb interstitial duplication on chromosome 3p.

Reappraising negative emotions reduces distress during the COVID-19 outbreak

In two studies, we examined the utility of intrinsic (i.e., self) versus extrinsic (i.e., other) reappraisal training for distress reduction during two consecutive COVID-19 lockdowns in Israel. In both Study 1 (n = 104) and Study 2 (n = 181), participants practiced the use of reappraisal for eight sessions across three weeks. Participants were trained to reappraise either a personal event (self-reappraisal group) or an incident presumably written by another participant (other-reappraisal group). Study 2 also included an untrained control group. Outcome measures were daily negative mood and psychological distress immediately at post-training and at a two-month follow-up. The results demonstrate a benefit for training compared to no training in lowering immediate post-training distress and daily negative emotions. However, this advantage disappeared at the two-month follow-up. In both studies, intrinsic reappraisal was associated with lower post-training distress than extrinsic reappraisal. Findings suggest reappraising negative experiences may lower distress at times of major contextual stress.

Emotion control training enhances reappraisal success among individuals with reported ADHD symptoms

Previous research indicates that training individuals to recruit cognitive control before exposure to negative pictures can facilitate the propensity to use reappraisal and reappraisal success. Individuals with attention deficit hyperactivity disorder (ADHD) experience difficulties in cognitive control and emotion regulation, so they may especially benefit from such training. Individuals reporting high ADHD symptoms and controls were randomly assigned to one of two training conditions. In the high emotion control (H-EC) training condition, negative pictures were typically preceded by a stimulus that recruits cognitive control. In contrast, in the low emotion control (L-EC) training condition, negative pictures were typically preceded by a stimulus that does not recruit cognitive control. Participants were then asked to recall an adverse personal event and to reappraise the event. As predicted, instructed reappraisal was more effective in reducing negative mood in the H-EC training compared to the L-EC training. Furthermore, compared to controls, individuals with reported ADHD symptoms showed a greater propensity to use reappraisal after writing the event and a more considerable reduction in event significance and negativity following the instructed reappraisal assignment. We argue that employing cognitive control over emotional information has a causal role in reappraisal use and success among individuals with ADHD symptoms.

Job burnout among Israeli healthcare workers during the first months of COVID-19 pandemic: The role of emotion regulation strategies and psychological distress

The current worldwide COVID-19 pandemic has elicited widespread concerns and stress. Arguably, healthcare workers are especially vulnerable to experience burnout during these times due to the nature of their work. Indeed, high prevalence of burnout was found among healthcare workers during the outbreak. However, the individual differences predicting burnout among healthcare workers during the pandemic have been understudied. The aim of the current study was, therefore, to identify risk and protective factors contributing to the severity of burnout among healthcare workers, above and beyond levels of current psychological distress. The survey was distributed online during the period April 13–28, 2020, approximately two months after the first COVID-19 case was identified in Israel. Ninety-eight healthcare workers completed an online survey administered cross-sectionally via the Qualtrics platform that included questionnaires assessing habitual emotion regulation strategies (i.e., trait worry, reappraisal, and suppression), psychological distress, COVID-19 related concerns, and burnout. A hierarchical linear regression analysis revealed that only trait worry and psychological distress were significant predictors of job burnout among healthcare workers. These findings highlight the role of maladaptive emotion regulation tendencies, specifically trait worry, in job burnout among healthcare workers. These findings have implications for both the assessment and treatment of healthcare workers. We discuss potential mechanisms and implications for practice.

The influence of inhibitory control on reappraisal and the experience of negative emotions

Inhibitory control (IC) enables goal-directed behaviour by reducing the interference of irrelevant information. Studies have shown that IC can downregulate performance-based behavioural and physiological measures of emotional reactivity. This study examined whether transient recruitment of IC can modulate self-reported negative feelings after exposure to negative or neutral content. Furthermore, it was tested if triggering IC can improve the ability to reduce the negativity of unpleasant content by reinterpreting its meaning (cognitive reappraisal). For this purpose, a combined flanker and cognitive reappraisal task was performed by 49 participants. The flanker task was used to prime IC before participants reappraised or observed negative and neutral content. Priming IC before negative images reduced self-reported negative feelings compared to when IC was not primed. In contrast, priming IC before neutral images increased negative feelings. Priming IC had no influence on the ability to reappraise negative emotional content. Finally, trait rumination was associated with higher emotional reactivity only when IC was not primed. These results illustrate the importance of IC in decreasing emotional reactivity after being exposed to negative content. IC is revealed as a mechanism that can dynamically modulate subjective emotional reactivity as a function of emotional context.

Trends in intra-aortic balloon pump use in cardiogenic shock in the post-SHOCK II trial era

Background

Myocardial infarction complicated by cardiogenic shock (MI-CS) has a poor prognosis, even with early revascularisation. Previously, intra-aortic balloon pump (IABP) use was thought to improve outcomes, but the SHOCK-II trial in 2012 found no survival benefit.

Purpose

This study aimed to determine the trends in IABP use in patients with MI-CS undergoing percutaneous intervention (PCI) over time and characteristics associated with use.

Methods

Between 2005–2018, patients presenting with MI-CS that underwent percutaneous coronary intervention (PCI) at a hospital participating in the Melbourne Interventional Group Registry were included. The primary outcome was the trend in IABP use over time. Secondary outcomes included mortality, 30-day MACCE (major adverse cardiovascular and cerebrovascular events) and predictors of outcome, determined via logistic regression.

Results

Of the 1,110 patients identified, IABP was used in 478 (43%). IABP was used more in patients with left main and left anterior descending culprit lesions (62% vs. 46%), lower ejection fraction (&lt;35%; 18% vs. 11%), and pre-procedural inotrope use (81% vs. 73%), all p&lt;0.05. IABP use was associated with higher inpatient bleeding (18% vs. 13%) and 30-day MACCE (58% vs. 51%), both p&lt;0.05. The rate of MI-CS increased over time, but after 2012 there was a decline in IABP use (Figure 1). IABP use was a predictor of 30-day MACCE (OR 1.6, 95% CI 1.18–2.29, p=0.003). However, IABP was not associated with in-hospital, 30-day or long-term mortality (45% vs. 47%, p=0.44; 46% vs. 50%, p=0.25; 60% vs. 62%, p=0.39).

Conclusions

Consistent with the SHOCK II trial, IABP use is not associated with reduced short- or long-term mortality, but in this study was associated with increased short-term adverse events. IABP use is declining, but is still used in sicker patients with greater myocardium at risk, given limited alternatives.

A multi-country test of brief reappraisal interventions on emotions during the COVID-19 pandemic

The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation. Participants from 87 countries and regions (n = 21,644) were randomly assigned to one of two brief reappraisal interventions (reconstrual or repurposing) or one of two control conditions (active or passive). Results revealed that both reappraisal interventions (vesus both control conditions) consistently reduced negative emotions and increased positive emotions across different measures. Reconstrual and repurposing interventions had similar effects. Importantly, planned exploratory analyses indicated that reappraisal interventions did not reduce intentions to practice preventive health behaviours. The findings demonstrate the viability of creating scalable, low-cost interventions for use around the world. PROTOCOL REGISTRATION: The stage 1 protocol for this Registered Report was accepted in principle on 12 May 2020. The protocol, as accepted by the journal, can be found at https://doi.org/10.6084/m9.figshare.c.4878591.v1.

Prestimulus Activity in the Cingulo-Opercular Network Predicts Memory for Naturalistic Episodic Experience

Human memory is strongly influenced by brain states occurring before an event, yet we know little about the underlying mechanisms. We found that activity in the cingulo-opercular network (including bilateral anterior insula [aI] and anterior prefrontal cortex [aPFC]) seconds before an event begins can predict whether this event will subsequently be remembered. We then tested how activity in the cingulo-opercular network shapes memory performance. Our findings indicate that prestimulus cingulo-opercular activity affects memory performance by opposingly modulating subsequent activity in two sets of regions previously linked to encoding and retrieval of episodic information. Specifically, higher prestimulus cingulo-opercular activity was associated with a subsequent increase in activity in temporal regions previously linked to encoding and with a subsequent reduction in activity within a set of regions thought to play a role in retrieval and self-referential processing. Together, these findings suggest that prestimulus attentional states modulate memory for real-life events by enhancing encoding and possibly by dampening interference from competing memory substrates.

Personalized cognitive training: Protocol for individual-level meta-analysis implementing machine learning methods

Accumulating evidence suggests that cognitive training may enhance well-being. Yet, mixed findings imply that individual differences and training characteristics may interact to moderate training efficacy. To investigate this possibility, the current paper describes a protocol for a data-driven individual-level meta-analysis study aimed at developing personalized cognitive training. To facilitate comprehensive analysis, this protocol proposes criteria for data search, selection and pre-processing along with the rationale for each decision. Twenty-two cognitive training datasets comprising 1544 participants were collected. The datasets incorporated diverse training methods, all aimed at improving well-being. These training regimes differed in training characteristics such as targeted domain (e.g., working memory, attentional bias, interpretation bias, inhibitory control) and training duration, while participants differed in diagnostic status, age and sex. The planned analyses incorporate machine learning algorithms designed to identify which individuals will be most responsive to cognitive training in general and to discern which methods may be a better fit for certain individuals.

Non-surgical treatment of vertical excess of the premaxilla in growing bilateral cleft lip and palate patients

Patients with bilateral complete cleft lip and palate (BCLP) may present a vertical excess of the premaxilla in childhood. This is a severe functional and aesthetic problem, where bone grafting is more challenging. The aim of this study was to describe a simple and reproducible non-surgical orthopaedic treatment for vertical excess of the premaxilla in the deciduous/early mixed dentition phase in BCLP patients. Six growing patients with complete BCLP with a severe vertical excess of the premaxilla were included. An intrusion device associated with a bonded rapid palatal expander was applied to intrude the premaxilla. Radiographic and photographic records obtained before and at the end of the orthodontic intrusion, at short- and long-term follow-up, were available. A flattening of the occlusal plane was achieved in all patients. Normalization of the position of the maxillary incisors and gingival display in relation to the upper lip was obtained, and an improvement in anterior nasal spine position was also observed in all cases. The novel technique described might be of assistance in treating BCLP children with vertical excess of the premaxilla during the deciduous/early mixed dentition phase. This simplified, easily reproducible method may allow the burden of care of this rare but complex problem affecting BCLP patients to be reduced significantly.

THU0386 PREDICTORS OF MAINTENANCE OF SECUKINUMAB TREATMENT IN A MULTICENTER COHORT OF 561 SPONDYLARTHRITIS

Objectives:

Secukinumab (SEC) is an interleukin-17 inhibitor used to treat patients with axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA). Drug maintenance is often used as a proxy for treatment effectiveness and safety in real life settings. We aim to assess SEC maintenance in routine clinical practice and to identify survival predictors associated.

Methods:

We conducted a retrospective, longitudinal, observational, multicenter study including all patients (pts) with axSpA or PsA who received at least 1 injection of SEC between July 2016 and October 2019. We collected patient’s demographics and clinic characteristics, SEC date of initiation and dosage and dosage modification of SEC, previous biologic Disease-modifying antirheumatic drugs (bDMARDs) and concomitant treatments. Date and reasons of discontinuation – i.e., lack of efficacy, safety issue, sustained remission or others – were collected. Several potential maintenance predictors were tested: age, gender, disease (axSpA or PsA), smoking status, bDMARDs history and concomitant treatment. Among patients with non-radiographic axSpA (nr-axSpA), evidence of MRI sacroiliitis or elevated CRP were also assessed as potential maintenance predictors. Drug maintenance was analyzed by the Kaplan-Meier method and adjusted for baseline factors were estimated by log rank analysis.

Results:

The main characteristics of the 561 pts included were the following: 363 (64.7%) axSpA, 198 (35.3%) PsA, 329 (58.6%) female, mean age 45,6 +/- 12 years, 221 (39.4%) smokers, 175 (31.2%) radiographic sacroiliitis, 259 (46.2%) MRI sacroiliitis, 198 (35.3%) elevated CRP, 247 (44.0%) HLA B27 positive, mean BASDAI 48,3 +/- 26.8%. SEC was associated to methotrexate (MTX) in 139 pts (24.8%) and was the first line bDMARD in 55 pts (9.8%). The median drug maintenance (MDM) of SEC was 79 weeks (wk) [73-84]. At 52 wk, 245 pts (60%) SpA were still treated with SEC. During the 3-year follow-up, 264 pts discontinued SEC: 180 (68.2%) pts for lack of effectiveness, 47 (17.8%) for adverse events, 14 (5.3%) for others and 23 (8.7%). SEC prescription as first line bDMARD was associated with longer survival versus second line or more: 111 wk [83-138] vs. 69 wk [57-80] (p=0. 017) (figure 1). MDM was not significantly different depending on gender, MTX combo, elevated CRP, axSpA vs PsA and smoking status. Among the nr-axSpA pts, MRI sacroiliitis or elevated CRP did not modify SEC maintenance (p=0.68) (figure 2).

Figure 2.

Secukinumab maintenance in nr-axSpA population

Conclusion:

In routine clinical practice, SEC median maintenance was 79 weeks. Fist line administration was the only independent factor associated with improved SEC retention. Lack of effectiveness was the most common reason of discontinuation.

FRI0348 PERSISTENCE OF SECUKINUMAB AND USTEKINUMAB IN PSORIATIC ARTHRITIS: A REAL-WORLD MULTICENTRIC COHORT OF 409 PATIENTS

Background:

Real-world data are missing for Ustekinumab (UST) and secukinumab (SEK) in psoriatic arthritis (PsA).

Objectives:

To evaluate the characteristics of the patients (pts) with PsA treated by UST or SEK and to assess real world persistence of UST and SEK in PsA.

Methods:

This is a retrospective, multicenter study of pts with PsA (CASPAR criteria or diagnosis confirmed by a rheumatologist) initiating UST or SEK with a follow-up ≥ 6 months from January 2011 to April 2019. The comparison of persistence between UST and SEK was analysed using a Cox model with an inverse probability of treatment weighting propensity score including 11 confounding factors. Subgroup analyses (age>65 years, gender, Body Mass Index (BMI), Charlson score>2, psoriasis, CRP>5mg/L, number (nb) of prior biotherapies, proportion of pts on maximum dose of UST or SEK, combination with methotrexate (MTX), enthesitic and axial forms of PsA) were also performed to test the heterogeneity of UST and SEK persistence. Finally, 2 sensitivity analyses were performed, first excluding the pts treated before the marketing authorization of SEK, and then excluding the pts that underwent a molecule switch. Causes of discontinuation were also collected.

Results:

406 pts were included: 245 with UST and 161 with SEK. At baseline before propensity score-matching, the UST group has a higher BMI (28.9 ± 6.4 kg/m2vs. 27.4 ± 6.0 kg/m2), more peripheral forms (98% vs. 90.8%), a higher nb of active smokers (27.1% vs. 19.9%), a higher frequency of psoriasis (96.3% vs. 83.2%), less MTX users (38.9% vs. 44.2%), a higher nb of pts with CRP >5mg/L (54.3% vs. 47%), a higher nb of pts naïve to biotherapies (22% vs. 13%) and a higher nb of pts with recommended dosing (97.3% vs 50.9%). The median persistence was 9.4 months and 14.7 months for UST and SEK, respectively. The persistence rate was lower in the UST group compared to the SEK group (40.9% vs. 59.1% % at 1 year; 26.4% vs. 38.0% at 2 years; weighted HR=1.42; 95% CI 1.07 to 1.92; p=0.015) (Fig 1). In subgroup analysis, combination with MTX was associated with a higher persistence rate in the patients with SEK compared to those receiving UST: 43.6% vs. 23.2% (HR=2.20; 95% CI 1.30 to 3.51; p=0.001), whereas no difference was observed in SEK and UST monotherapy: 33.8% vs 28.4%, respectively (HR=1.06; 95% CI 0.74 to 1.53; p=0.75) (Fig 2). A similar difference was found in the sensitivity analyses, with however a difference at the limit of significance for the analysis excluding pts with a molecule switch (adjusted HR=1.35; IC95% 0.96 to 1.92; p=0.085). The causes of discontinuation were due to inefficacy in 85% of cases and an adverse event in 12% of cases (19% in the SEK group and 9% in the UST group).

Conclusion:

In this first real-world study comparing UST and SEK persistence in PsA, the persistence of SEK was longer than that of UST. Subgroup analysis revealed this difference of persistence was restricted to patients treated in combination with MTX.

The quality of informed consent obtained for orthopedic surgeries-elective versus trauma: A prospective interview-based study

BACKGROUND

Orthopedic surgeons routinely obtain informed consent prior to surgery. Legally adequate informed consent necessitates a thorough discussion of treatment options and risks and proper documentation. However, the quality of informed consent in orthopedic trauma patients is an under-researched area.

PURPOSE

To assess the quality of the informed consent process in trauma compared with elective orthopedic patients and to assess patients' emotional state at the time of signing consent form.

METHODS

Sixty-two consecutive patients undergoing either elective total joint arthroplasty ( N = 32) or orthopedic trauma surgery ( N = 30) were included. The data were collected through personal interviews using a proposed informed consent score. The interviews were held after obtaining the informed consent and before the index procedure. Patients were asked to describe their diagnosis, the surgical procedure, its' benefits, and risks as well as alternative treatments.

RESULTS

Mean age differed significantly between elective and trauma group patients (66.1 vs. 51.6, respectively, p < 0.01), while gender and education level were comparable ( p = 0.075, p = 0.55, respectively). The quality of consent was significantly better for patients with post-high-school education compared to elementary education level (consent score: 16.9 ± 4.1 vs. 12.2 ± 5.5, p = 0.021). Patients in the elective group showed an overall higher quality of consent, as reflected by a mean score of 17.03 ± 4.2 versus a mean score of only 13.73 ± 4.7 in the trauma group ( p = 0.005, 95% CI: 1.02-5.57). Specifically, trauma patients demonstrated a lower comprehension of the diagnosis, the benefits of surgical treatment, the possible complications, and the expected postoperative course.

CONCLUSION

Patients undergoing trauma surgery are significantly more likely to have an inadequate understanding of the proposed treatment. These findings raise questions concerning the validity of consent from trauma patients.

European Position Paper on Rhinosinusitis and Nasal Polyps 2020

The European Position Paper on Rhinosinusitis and Nasal Polyps 2020 is the update of similar evidence based position papers published in 2005 and 2007 and 2012. The core objective of the EPOS2020 guideline is to provide revised, up-to-date and clear evidence-based recommendations and integrated care pathways in ARS and CRS. EPOS2020 provides an update on the literature published and studies undertaken in the eight years since the EPOS2012 position paper was published and addresses areas not extensively covered in EPOS2012 such as paediatric CRS and sinus surgery. EPOS2020 also involves new stakeholders, including pharmacists and patients, and addresses new target users who have become more involved in the management and treatment of rhinosinusitis since the publication of the last EPOS document, including pharmacists, nurses, specialised care givers and indeed patients themselves, who employ increasing self-management of their condition using over the counter treatments. The document provides suggestions for future research in this area and offers updated guidance for definitions and outcome measurements in research in different settings. EPOS2020 contains chapters on definitions and classification where we have defined a large number of terms and indicated preferred terms. A new classification of CRS into primary and secondary CRS and further division into localized and diffuse disease, based on anatomic distribution is proposed. There are extensive chapters on epidemiology and predisposing factors, inflammatory mechanisms, (differential) diagnosis of facial pain, allergic rhinitis, genetics, cystic fibrosis, aspirin exacerbated respiratory disease, immunodeficiencies, allergic fungal rhinosinusitis and the relationship between upper and lower airways. The chapters on paediatric acute and chronic rhinosinusitis are totally rewritten. All available evidence for the management of acute rhinosinusitis and chronic rhinosinusitis with or without nasal polyps in adults and children is systematically reviewed and integrated care pathways based on the evidence are proposed. Despite considerable increases in the amount of quality publications in recent years, a large number of practical clinical questions remain. It was agreed that the best way to address these was to conduct a Delphi exercise . The results have been integrated into the respective sections. Last but not least, advice for patients and pharmacists and a new list of research needs are included.

From Surviving to Thriving in the Face of Threats: The Emerging Science of Emotion Regulation Training

A key survival skill is the ability to regulate your emotions so as to respond adaptively to life's challenges. As such, it is essential to understand how we can improve this ability through training. While this is still a new area of research, to date, behavioral and brain studies have taken one of two approaches: either training individuals to implement strategies that directly impact current emotional responses, or training a cognitive control ability (like working memory, selective attention, response inhibition) to strengthen or tune control processes that can support regulation to subsequently encountered events. Behavioral data highlight the importance of tailoring training to an individual and their emotional situation. Brain data suggest that training impacts domain general cognitive control systems and their interaction with subcortical regions (mainly the amygdala). Future progress will depend on systematic examination of the mechanisms involved in training effectiveness and the populations that may benefit from training.

EACR-MRS conference on Seed and Soil: In Vivo Models of Metastasis

New experimental tools are urgently required to better understand the metastatic process. The importance of such tools is underscored by the fact that many anti-cancer therapies are generally ineffective against established metastases. This makes a major contribution to the fact that metastatic spread is responsible for over 90% of cancer patient deaths. It was therefore timely that the recent "Seed and Soil: In Vivo Models of Metastasis" conference held in Berlin, Germany (27-29 of November 2017) aimed to give an in-depth overview of the latest research models and tools for studying metastasis, and to showcase recent findings from world-leading metastasis researchers. This Meeting Report summarises the major themes of this ground-breaking conference.

Impact of QuickFISH in addition to antimicrobial stewardship on vancomycin use and resource utilization in cancer patients with coagulase-negative staphylococcal blood cultures

OBJECTIVE

To evaluate the impact of rapidly identifying coagulase-negative staphylococci (CoNS) from positive blood cultures combined with an established antimicrobial stewardship (AS) programme at a tertiary cancer centre.

METHODS

We compared cancer patients ≥18 years old who between 01/1/13 and 12/31/13 had one or more positive CoNS blood culture(s) identified by Staphylococcus QuickFISH® (a peptide nucleic acid fluorescence in situ hybridization assay) with cancer patients ≥18 years old who had CoNS identified by standard microbiological techniques between 01/01/11 and 12/31/11 (baseline). Positive blood culture results were reported to the clinician by microbiology staff; restricted antibiotics (e.g., vancomycin) required approval by the AS team.

RESULTS

There were 196 baseline and 103 QuickFISH patients. Faster median time to organism identification (33 (IQR 27-46) versus 49 (IQR 39-63) hours, p < 0.001), more vancomycin avoidance (51/103 (50%) versus 60/196 (31%), p 0.002), shorter median antibiotic duration (1 (IQR 0-3) versus 2 (IQR 0-6) days, p 0.019), fewer central venous catheter (CVC) removals (14/78 (18%) versus 57/160 (36%), p 0.004), and reduced vancomycin level monitoring (16/52 (31%) versus 71/136 (52%), p 0.009) were observed in the QuickFISH group. QuickFISH implementation was predictive of a lower likelihood of antibiotic therapy prescription (OR 0.35, 95%CI 0.20-0.62, p < 0.001). Prior transplant (RR 1.47, 95%CI 1.13-1.92, p 0.004), neutropenia (RR 1.47, 95%CI 1.09-1.99, p 0.012), multiple positive blood cultures (RR 4.23, 95%CI 3.23-5.54, p < 0.001), and CVC (RR 1.60, 95%CI 1.02-2.53, p 0.043) were independent factors for antibiotic duration.

CONCLUSIONS

QuickFISH implementation plus AS support leads to greater avoidance of vancomycin therapy and improved resource utilization in cancer patients with CoNS blood cultures.

Fibroblasts drive an immunosuppressive and growth-promoting microenvironment in breast cancer via secretion of Chitinase 3-like 1

Cancer-Associated Fibroblasts (CAFs) are the most prominent stromal cell type in breast tumors. CAFs promote tumor growth and metastasis by multiple mechanisms, including by mediating tumor-promoting inflammation. Immune modulation in the tumor microenvironment plays a central role in determining disease outcome. However, the functional interactions of CAFs with immune cells are largely unknown. Here we report a novel signaling axis between fibroblasts, cancer cells and immune cells in breast tumors that drives an immunosuppressive microenvironment, mediated by CAF-derived Chi3L1. We demonstrate that Chi3L1 is highly upregulated in CAFs isolated from mammary tumors and pulmonary metastases of transgenic mice, and in the stroma of human breast carcinomas. Genetic ablation of Chi3L1 in fibroblasts in vivo attenuated tumor growth, macrophage recruitment and reprogramming to an M2-like phenotype, enhanced tumor infiltration by CD8⁺ and CD4⁺ T cells and promoted a Th1 phenotype. These results indicate that CAF-derived Chi3L1 promotes tumor growth and shifts the balance of the immune milieu towards type 2 immunity. Taken together, our findings implicate fibroblast-derived Chi3L1 as a novel key player in the complex reciprocal interactions of stromal cells that facilitate tumor progression and metastasis, and suggest that targeting Chi3L1 may be clinically beneficial in breast cancer.

Erdheim-Chester disease: 25-year history with early CNS involvement

We report a case of Erdheim-Chester disease (ECD) with a 25-year history following initial presentation with diabetes insipidus and brainstem involvement. The exceptionally long history is particularly notable, given that ECD is a life-threatening disorder and there is a recognised association between central nervous system involvement and poor outcome. The case is a timely reminder of the presenting features of the condition, given the emergence of potential new treatment options.

Thermomechanical Mechanisms of Reducing Ice Adhesion on Superhydrophobic Surfaces

Superhydrophobic (SH) coatings have been shown to reduce freezing and ice nucleation rates, by means of low surface energy chemistry tailored with nano/micro roughness. Durability enhancement of SH surfaces is a crucial issue. Consequently, the present research on reducing ice adhesion is based on radiation-induced radical reaction for covalently bonding SiO2 nanoparticles to polymer coatings to obtain durable roughness. Results indicated that the proposed approach resulted in SH surfaces having high contact angles (>155°) and low sliding angles (<5°) with improved durability and transparency. In a subsequent stage, the synthesized SH coating was investigated for its icephobic characteristics using a variety of substrates. Results indicated that supercooled water drops bounced back when impinging on SH polycarbonate substrate and froze on SH copper substrate held at -10 to -30 °C and were easily peeled off when coated by ice formed during exposure to air/supercooled water drops at -20 °C. The ice shear adhesion investigation (at -20 °C) demonstrated reduction of shear adhesion to a variety of SH treated substrates having low thermal expansion coefficient (copper and aluminum) and high thermal expansion coefficient (polycarbonate and poly(methyl methacrylate)). It was concluded that the thermal mismatch between the adhering ice and the various substrates and its resultant interfacial thermal stresses affect the adhesion strength of the ice to the respective substrate.

Dynamic analysis of immune and cancer cell interactions at single cell level in microfluidic droplets

Cell-cell communication mediates immune responses to physiological stimuli at local and systemic levels. Intercellular communication occurs via a direct contact between cells as well as by secretory contact-independent mechanisms. However, there are few existing methods that allow quantitative resolution of contact-dependent and independent cellular processes in a rapid, precisely controlled, and dynamic format. This study utilizes a high-throughput microfluidic droplet array platform to analyze cell-cell interaction and effector functions at single cell level. Controlled encapsulation of distinct heterotypic cell pairs was achieved in a single-step cell loading process. Dynamic analysis of dendritic cell (DC)-T cell interactions demonstrated marked heterogeneity in the type of contact and duration. Non-stimulated DCs and T cells interacted less frequently and more transiently while antigen and chemokine-loaded DCs and T cells depicted highly stable interactions in addition to transient and sequential contact. The effector function of CD8⁺ T cells was assessed via cytolysis of multiple myeloma cell line. Variable cell conjugation periods and killing time were detected irrespective of the activation of T cells, although activated T cells delivered significantly higher cytotoxicity. T cell alloreactivity against the target cells was partially mediated by secretion of interferon gamma, which was abrogated by the addition of a neutralizing antibody. These results suggest that the droplet array-based microfluidic platform is a powerful technique for dynamic phenotypic screening and potentially applicable for evaluation of novel cell-based immunotherapeutic agents.

The interaction between emotion and executive control: Comparison between visual, auditory, and tactile modalities

The reciprocal connections between emotion and attention are vital for adaptive behaviour. Previous results demonstrated that the behavioural effects of emotional stimuli on performance are attenuated when executive control is recruited. The current research studied whether this attenuation is modality dependent. In two experiments, negative and neutral pictures were presented shortly before a visual, tactile, or auditory target in a Simon task. All three modalities demonstrated a Simon effect, a conflict adaptation effect, and an emotional interference effect. However, the interaction between picture valence and Simon congruency was found only in the visual task. Specifically, when the Simon target was visual, emotional interference was reduced during incongruent compared to congruent trials. These findings suggest that although the control-related effects observed in the Simon tasks are not modality dependent, the link between emotion and executive control is modality dependent. Presumably, this link occurs only when the emotional stimulus and the target are presented in the same modality.
