Feeling Seen, Being Heard: Perspectives of Patients Suffering from Mental Illness on the Possibility of Physician-Assisted Death in the Netherlands
Authors: Pronk Rosalie , Willems Dick L. , van de Vathorst Suzanne 
Published: June 2021

AbstractPhysician-assisted death (PAD) for patients suffering from a mental illness is allowed in the Netherlands under certain conditions but is a very controversial topic, mainly discussed by ethicists and physicians. The voice of the patient is rarely included in the debate, so we know little about what their views on the topic are. We aim to understand the views of patients with mental illness and wish to die with regard to the possibility of PAD in the Netherlands. The data for this qualitative study were collected through 21 in-depth interviews with Dutch patients who have a wish for PAD as a result of suffering from a mental illness. We identified four themes in relation to the meaning of PAD for the patients suffering from mental illness and wish to die. These themes are (1) Autonomy and self-determination, (2) ending the suffering, (3) recognition, and (4) a dignified end-of-life. The option of PAD for patients suffering from mental illnesses was considered of great importance to the patients who have a wish to die. We highlight the importance of ‘recognition’ for the situation of the patient, as this could lead to new perspective. We argue that psychiatrists need to reflect on providing this recognition in earlier phases of treatment, taking seriously and discussing a wish for PAD in treatment is beneficial to patients. It provides space for the patient to discuss their wishes and could cause them not wanting to die anymore.

Video- und protokollbasierte Reflexionen eigener praktischer Unterrichtserfahrungen im Lehramtsstudium
Authors: Kücholl Denise , Lazarides Rebecca 
Published: June 2021

ZusammenfassungDie Reflexion praktischer Unterrichtserfahrungen ermöglicht es Lehramtsstudierenden theoretische Wissensaspekte und praxisrelevante Erkenntnisse miteinander zu verknüpfen. Die vorliegende Studie untersucht die Bedeutung des Mediums der Reflexion (eigenes Video vs. fremdes Video vs. Protokoll) sowie der Art der reflektierten Unterrichtssituation (positiv vs. herausfordernd) für die Reflexionsprozesse Lehramtsstudierender. Darüber hinaus wird untersucht, auf welchen Ebenen (Basal‑, Sicht- und Tiefenstrukturen) das Unterrichtsgeschehen reflektiert wird. Datengrundlage der quasi-experimentellen Studie sind Unterrichtsreflexionen von 55 Lehramtsstudierenden, die inhaltsanalytisch ausgewertet wurden. Die Ergebnisse zeigen, dass Lehramtsstudierende die Tiefenstrukturen des Unterrichts reflektieren, wenn die Reflexion von Situationen, die als positiv erlebt wurden, anhand fremder Unterrichtsvideos geschieht. Bei der Reflexion von herausfordernden Unterrichtssituationen werden Tiefenstrukturen sowohl anhand von fremden Videos als auch anhand von Protokollen reflektiert. Die Implikationen der Ergebnisse für die Lehrkräftebildung werden im Hinblick auf die Reflexion von Unterrichtspraxis diskutiert.
Post-operative Anemia After Major Surgery: a Brief Review
Authors: Kalra Smita K. , Thilagar Bright , Khambaty Maleka , Manjarrez Efren 
Published: June 2021

Abstract
Purpose of Review
Anemia is a very common complication in the post-operative period. Post-operative anemia is associated with poor outcomes including but not limited to infections, increased length of stay, circulatory overload, and mortality. The strategy of patient blood management focuses on three pillars that include the detection and treatment of pre-operative anemia; reduction of peri-operative blood loss; and harnessing and optimizing the patient-specific physiological reserve of anemia.

Recent Findings
Multiple studies in surgical patients have been conducted to study various methods of management of post-operative anemia. Recent advances in surgical techniques have also been studied to minimize blood loss. There is a widespread consensus on the use of intravenous iron in hospitalized post-operative patients after major surgery.

Summary
We discuss the most common causes of post-operative anemia and management focusing on measures to reduce blood loss and measures to increase red blood cell (RBC) mass. In this brief review, we present updates from the most relevant articles in the past 5 years and include updates from the 2018 international consensus statement on the management of post-operative anemia after major surgical procedures.

Abstract
Purpose
We aimed at investigating the lifetime prevalence of mood, eating and panic disorders in a large sample of obese patients referred to bariatric surgery. We also explored the patterns of psychiatric comorbidity and their relationship with Body Mass Index (BMI).

Methods
The sample was composed of patients consecutively referred for pre-surgical evaluation to the Obesity Center of Pisa University Hospital between January 2004 and November 2016. Clinical charts were retrieved and examined to obtain sociodemographic information, anthropometric variables and lifetime psychiatric diagnoses according to DSM-IV criteria.

Results
A total of 871 patients were included in the study; 72% were females, and most patients had BMI ≥ 40 kg/m2 (81%). Overall, 55% of the patients were diagnosed with at least one lifetime psychiatric disorder. Binge eating disorder (27.6%), major depressive disorder (16%), bipolar disorder type 2 (15.5%), and panic disorder (16%) were the most common psychiatric diagnoses. Mood disorders showed associations with panic disorder (OR = 2.75, 95% CI = 1.90–3.99, χ2 = 41.85, p = 0.000) and eating disorders (OR = 2.17, 95% CI 1.64–2.88, χ2 = 55.54, p = 0.000). BMI was lower in patients with major depressive disorder (44.9 ± 7.89) than in subjects without mood disorders (46.75 ± 7.99, padj = 0.017).

Conclusion
Bariatric patients show high rates of psychiatric disorders, especially binge eating and mood disorders. Longitudinal studies are needed to explore the possible influence of such comorbidities on the long-term outcome after bariatric surgery.

AbstractWe aim to develop a deep-learning-based method for automatic proximal femur segmentation in quantitative computed tomography (QCT) images. We proposed a spatial transformation V-Net (ST-V-Net), which contains a V-Net and a spatial transform network (STN) to extract the proximal femur from QCT images. The STN incorporates a shape prior into the segmentation network as a constraint and guidance for model training, which improves model performance and accelerates model convergence. Meanwhile, a multi-stage training strategy is adopted to fine-tune the weights of the ST-V-Net. We performed experiments using a QCT dataset which included 397 QCT subjects. During the experiments for the entire cohort and then for male and female subjects separately, 90% of the subjects were used in ten-fold stratified cross-validation for training and the rest of the subjects were used to evaluate the performance of models. In the entire cohort, the proposed model achieved a Dice similarity coefficient (DSC) of 0.9888, a sensitivity of 0.9966 and a specificity of 0.9988. Compared with V-Net, the Hausdorff distance was reduced from 9.144 to 5.917 mm, and the average surface distance was reduced from 0.012 to 0.009 mm using the proposed ST-V-Net. Quantitative evaluation demonstrated excellent performance of the proposed ST-V-Net for automatic proximal femur segmentation in QCT images. In addition, the proposed ST-V-Net sheds light on incorporating shape prior to segmentation to further improve the model performance.
Quantitative analysis of trade networks: data and robustness

Published: June 2021

AbstractA common issue in trade network analysis is missing data, as some countries do not report trade flows. This paper explores what constitutes suitable data, how to deal with missing data, and demonstrates the results using key network measures. All-to-all potential connectivity of trade between countries is considered as a starting point, in contrast to the common approach of analyzing trade networks using only the countries that actually report trade flows. In order to fill the gap between the two approaches, a more complete dataset than just the dataset of trade between reporting countries is reconstructed and the robustness of studying this bigger dataset is examined. The difference between imputed and actual network adjacency matrices is evaluated based on several centrality measures. The results are illustrated using ten commodity groups from the United Nations Database, which demonstrate that under the proposed reconstruction procedure the ranks of the countries do not change significantly as the size of the imputed network becomes bigger or smaller. Further, the degree distributions of networks based on reporting countries and trading partners are the same to within their uncertainties. So, it is robust to study the imputed bigger network that provides richer insights into trade relations, particularly for nonreporting countries.

Published: June 2021

Abstract

Introduction
The COVID-19 pandemic can cause emotional distress, which can in turn lead to the development of mental and physical symptoms.

Aim
We examined the association of the COVID-19 outbreak and the mental, physical and sexual health of the female Polish population.

Methods
Data were collected in an online survey distributed on social media from April 22, 2020 through to May 7, 2020. The data collection began one month after the start of lockdown in Poland.

Main Outcome Measure
Women were asked to complete the Beck Depression Inventory (BDI) and the Female Sexual Function Index (FSFI) questionnaires.

Results
Overall, 1644 women (median age 23 years) took part in the survey. They reported a lower frequency of sexual activity (P &lt; .001) and a lower libido level (P &lt; .001) during the pandemic then before it. 57.5% of the study group (n = 944) strongly agreed or agreed that fear of the health condition of loved ones was a source of stress and depressed mood. The average BDI-II total score was 11 (range 0-51; IQR 5-18), which corresponds to minimal depression. The average FSFI total score was 27.01 ± 7.61 (range 2-36). The FSFI and BDI scores were significantly correlated (P &lt; .001). The FSFI score was significantly correlated with the presence of any comorbid chronic disease, the intensity of the fear of infection and fear of health conditions, perceived loneliness, and the being up to date with media news. The BDI score was significantly correlated with age, the intensity of the fear of infection and fear of health conditions, perceived loneliness, being up to date with media news, and the more frequent use of stimulants.

Conclusions
The COVID-19 lockdown setting was associated with a high occurrence of depressive symptoms and increased risk of sexual dysfunction with decreased libido and lower sexual frequency the most commonly reported issues.
Epistemic Obligations of the Laity
Authors: Millar Boyd 
Published: June 2021

AbstractVery often when the vast majority of experts agree on some scientific issue, laypeople nonetheless regularly consume articles, videos, lectures, etc., the principal claims of which are inconsistent with the expert consensus. Moreover, it is standardly assumed that it is entirely appropriate, and perhaps even obligatory, for laypeople to consume such anti-consensus material. I maintain that this standard assumption gets things backwards. Each of us is particularly vulnerable to false claims when we are not experts on some topic – such falsehoods have systematic negative impacts on our doxastic attitudes that we can neither prevent nor correct. So, when there is clear expert consensus on a given scientific issue, while it is permissible for experts to consume anti-consensus material, laypeople have an epistemic obligation to avoid such material. This argument has important consequences for philosophical discussions of our epistemic obligations to perform or omit belief-influencing actions. Such discussions typically abstract away from the important differences between experts and laypeople. Accordingly, we should reject this typical practice as problematic, and insist instead that laypeople and experts have fundamentally different epistemic obligations.
Toponyms on the ice: The symbolic and iconographical role of Antarctic research base names
Authors: Lindsay Neil , Yoon Hong-Key 
Published: June 2021

Abstract
Place names serve a symbolic function in enforcing colonial power over landscapes. Within colonial locales, place names reproduce and reflect the ideological goals of settlers to reinforce or claim space for an individual, group or nation. One toponymically understudied colonial region where place names play a prominent role is the Antarctic, where the names of research bases promote the cultural power of settler nations to symbolically claim the continental landscape. As Antarctica is a geopolitically contested space, Antarctic research base names serve as an ideological purpose in reinforcing claims to the Antarctic, contrasting the ostensibly scientific purpose of research bases. This paper examines Antarctic research base names by categorising and interpreting their naming sources through a critical toponymic lens. This paper discusses general Antarctic naming trends and establishes possible reasons and outcomes of their employment, using three primary arguments: (1) Antarctic research base names are often nationalistic and reflect the implicit geopolitical goals of settler nations, (2) Antarctic research base names reflect and reproduce ongoing polar colonialism and (3) contestation over the naming of Antarctic research bases exemplifies the iconographical and cultural conflict between Antarctic nations. This paper seeks to provoke a future toponymic investigation into Antarctica and study Antarctic cultural landscapes more generally.
Dynamic modeling and power optimization of a 4R

P

SP+PS parallel flight simulator machine
Authors: Zarkandi Soheil 
Published: June 2021

AbstractReducing consumed power of a robotic machine has an essential role in enhancing its energy efficiency and must be considered during its design process. This paper deals with dynamic modeling and power optimization of a four-degrees-of-freedom flight simulator machine. Simulator cabin of the machine has yaw, pitch, roll and heave motions produced by a 4RPSP+PS parallel manipulator (PM). Using the Euler–Lagrange method, a closed-form dynamic equation is derived for the 4RPSP+PS PM, and its power consumption is computed on the entire workspace. Then, a newly introduced optimization algorithm called multiobjective golden eagle optimizer is utilized to establish a Pareto front of optimal designs of the manipulator having a relatively larger workspace and lower power consumption. The results are verified through numerical examples.
LEXICAL COMPETENCE UNDERLYING SECOND LANGUAGE WORD ASSOCIATION TASKS
Authors: Eguchi Masaki , Suzuki Shungo , Suzuki Yuichi 
Published: June 2021

AbstractThis study investigated the constructs underlying second language (L2) word association (WA) with regard to three dimensions of lexical competence—size, organization, and accessibility—and the lexical performance of speech. One-hundred and thirteen Japanese learners of English completed a computer-delivered oral WA task along with three vocabulary tasks: a form-recall gap-filling task (size), a primed lexical decision task (organization and accessibility), and an oral cartoon narrative (lexical richness). Regression analyses explored how well these lexical competence and performance scores predicted two WA outcome variables: response profiles and response times. Form-recall vocabulary knowledge, (collocational) priming, and lexical richness explained a large amount of variance in WA response type profiles (Nagelkerke’s pseudo R2 = .901). Form-recall vocabulary knowledge and lexical decision time explained 28.5% of the variance of WA response times. A three-stage model of L2 WA task performance is proposed to account for the constructs underlying WA performance.

Published: June 2021

Abstract
Characteristics and research collaboration of registered systematic reviews (SRs) on treatment modalities for coronavirus disease-2019 (COVID-19) remain unclear. This study analysed research collaboration, interventions and outcome measures in registered SRs on COVID-19 treatments and pointed out the relevant problems. PROSPERO (international prospective register of systematic reviews) was searched for SRs on COVID-19 treatments as of 2 June 2020. Excel 2016 was used for descriptive analyses of the extracted data. VOSviewer 1.6.14 software was used to generate network maps for collaborations between countries and institutions. A total of 189 SRs were included, which were registered by 301 institutions from 39 countries. China (69, 36.50%) exhibited the highest output. Cooperation between countries was not close enough. As an institution, the Chengdu University of Traditional Chinese Medicine (7, 3.70%) had the highest output. There was close cooperation between institutions. Interventions included antiviral therapy (81, 42.86%), respiratory support (16, 8.47%), circulatory support (11, 5.82%), plasma therapy for convalescent patients (11, 5.82%), immunotherapy (9, 4.76%), TCM (traditional Chinese medicine) treatment (9, 4.76%), rehabilitation treatment (5, 2.65%), anti-inflammatory treatment (16, 8.47%) and other treatments (31, 16.40%). Concerning antiviral therapy (81, 42.86%), the most commonly used antiviral agents were chloroquine/hydroxychloroquine (26, 13.76%), followed by remdesivir (12, 6.35%), lobinavir/ritonavir (11, 5.82%), favipiravir (5, 2.65%), ribavirin (5, 2.65%), interferon (5, 2.65%), abiron (4, 2.12%) and abidor (4, 2.12%). The most frequently used primary and secondary outcomes were the mortality rate (92, 48.68%) and hospital stay length (48, 25.40%), respectively. The expression of the outcomes was not standardised. Many COVID-19 SRs on treatment modalities have been registered, with a low completion rate. Although there was some collaboration between countries and institutions in the currently registered SRs on treatment modalities for COVID-19 on PROSPERO, cooperation between countries should be further enhanced. More attention should be directed towards identifying deficiencies of outcome measures, and the standardisation of results should be maximised.
Performance Validity and Outcome of Cognitive Behavior Therapy in Patients with Chronic Fatigue Syndrome

Published: June 2021

AbstractObjective:There is limited research examining the impact of the validity of cognitive test performance on treatment outcome. All known studies to date have operationalized performance validity dichotomously, leading to the loss of predictive information. Using the range of scores on a performance validity test (PVT), we hypothesized that lower performance at baseline was related to a worse treatment outcome following cognitive behavioral therapy (CBT) in patients with Chronic Fatigue Syndrome (CFS) and to lower adherence to treatment.Method:Archival data of 1081 outpatients treated with CBT for CFS were used in this study. At baseline, all patients were assessed with a PVT, the Amsterdam Short-Term Memory test (ASTM). Questionnaires assessing fatigue, physical disabilities, psychological distress, and level of functional impairment were administered before and after CBT.Results:Our main hypothesis was not confirmed: the total ASTM score was not significantly associated with outcomes at follow-up. However, patients with a missing follow-up assessment had a lower ASTM performance at baseline, reported higher levels of physical limitations, and completed fewer therapy sessions.Conclusions:CFS patients who scored low on the ASTM during baseline assessment are more likely to complete fewer therapy sessions and not to complete follow-up assessment, indicative of limited adherence to treatment. However, if these patients were retained in the intervention, their response to CBT for CFS was comparable with subjects who score high on the ASTM. This finding calls for more research to better understand the impact of performance validity on engagement with treatment and outcomes.

AbstractObjective:Cognitive dysfunction is common in multiple sclerosis (MS). The Brief International Cognitive Assessment for MS (BICAMS) battery of tests has been suggested as a measure for the evaluation of the cognitive status of MS patients. This study aims to validate the BICAMS battery in the Russian population of MS patients.Methods:Age- and sex-matched MS patients (n = 98) and healthy individuals (n = 86) were included in the study. Symbol Digit Modalities Test (SDMT), California Verbal Learning Test, 2nd edition (CVLT-II) and the Brief Visuospatial Memory Test – Revised (BVMT-R) were administered to all participants. The battery was readministered 1 month later to 44 MS patients to investigate the test–retest reliability.Results:MS patients exhibited a significantly lower performance in testing with BICAMS than the control group in all three neuropsychological tests. Test–retest reliability was good for SDMT and CVLT-II (r = .82 and r = .85, respectively) and adequate for BVMT-R (r = .70). Based on the proposed criterion for impairment as z score below 1.5 SD the mean of the control group, we found that 34/98 (35%) of MS patients were found impaired at least in one cognitive domain. Patients with Expanded Disability Status Scale score ≥3.5 performed significantly worse than controls (SDMT, p < .0001; CVLT–II, p = .03; BVMT-R, p = .0004), while those with ≤3.0 scores did not.Conclusion:This study demonstrates that the BICAMS battery is a valid instrument to identify cognitive impairment in MS patients and it can be recommended for routine use in the Russian Federation.
