Hamiltonian Berge cycles in random hypergraphs
Authors: Bal Deepak , Berkowitz Ross , Devlin Pat , Schacht Mathias 
Published: September 2020

AbstractIn this note we study the emergence of Hamiltonian Berge cycles in random r-uniform hypergraphs. For
$r\geq 3$
we prove an optimal stopping time result that if edges are sequentially added to an initially empty r-graph, then as soon as the minimum degree is at least 2, the hypergraph with high probability has such a cycle. In particular, this determines the threshold probability for Berge Hamiltonicity of the Erdős–Rényi random r-graph, and we also show that the 2-out random r-graph with high probability has such a cycle. We obtain similar results for weak Berge cycles as well, thus resolving a conjecture of Poole.
Transdiagnostic perspective on psychological inflexibility and emotional dysregulation
Authors: Faustino Bruno 
Published: September 2020

AbstractBackground:Psychological inflexibility and emotional dysregulation are a hallmark of psychopathology, being intrinsically embedded in emotional and personality disorders. However, the transdiagnostic mechanisms of psychological inflexibility and emotional dysregulation domains are still a matter of discussion.Aims:The present study aims to explore the relationships between cognitive fusion (as a measure of psychological inflexibility), emotion regulation strategies, such as cognitive reappraisal and emotional suppression and emotional dysregulation domains in two different samples.Method:In a cross-sectional design, 297 individuals were assessed with self-report measures and divided into non-clinical (n= 231) and clinical samples (n= 66), according to diagnosis.Results:Results showed that the degree of cognitive fusion was higher in the clinical sample. However, significant correlations between cognitive fusion, emotional regulation strategies and emotional dysregulation domains were found in the two samples. Cognitive reappraisal and emotional dysregulation domains predicted cognitive fusion and mediated the relationship between cognitive fusion and symptomatology in the two samples.Conclusions:Relationships between cognitive fusion and emotional dysregulation domains were found independent of diagnosis. The implementation of emotion regulation strategies may be related to individual differences. However, cognitive fusion, reappraisal and lack of strategies may be core transdiagnostic features in psychological inflexibility and emotion dysregulation.

AbstractObjectives:To validate an Arabic version of the Eating Attitude Test (EAT-26) and identify factors (such as depression, stress, anxiety and body dissatisfaction) that might be associated with disordered eating among a sample of the Lebanese population.Design:Cross-sectional study.Setting:All Lebanese governorates.Participants:A total of 811 participants randomly selected participated in this 5-month study (January–May 2018).Results:The EAT-26 scale items converged over a solution of six factors that had an eigenvalue over 1, explaining a total of 60·07 % of the variance (Cronbach’sα= 0·895). The prevalence of disordered eating attitudes was 23·8 %. Higher EAT-26 scores (disordered eating attitudes) were significantly associated with higher depression (β= 0·325), higher emotional eating (β= 0·083), daily weighing (β= 3·430), higher physical activity (β= 0·05), starving to reduce weight (β= 4·94) and feeling pressure from TV/magazine to lose weight (β= 3·95).Conclusions:The Arabic version of EAT-26 can be a useful instrument for screening and assessing disordered eating attitudes in clinical practice and research. Some factors seem to be associated with more disordered eating attitudes among participants for whom psychological counseling may be needed. Yet, our findings are considered preliminary, and further studies are warranted to confirm them.
Pension communication, knowledge, and behaviour
Authors: Debets Steven , Prast Henriette , Rossi Mariacristina , van Soest Arthur 
Published: September 2020

AbstractMany recent pension reforms require individuals to make more decisions on supplementary savings, investment choices, etc. Governments and the pension industry try to assist individuals through pension communication but little is known about the effectiveness of such policies. This paper uses Dutch longitudinal data to analyse the causal links between communication, pension knowledge, and conscious pension decision-making. A robust finding is that pension knowledge has a positive causal effect on active pension decision-making. Providing an annual pension statement might have a small positive effect on pension knowledge, but this result is sensitive to the identifying assumptions.

AbstractObjectiveFew studies have examined burnout in psychosocial oncology clinicians. The aim of this systematic review was to summarize what is known about the prevalence and severity of burnout in psychosocial clinicians who work in oncology settings and the factors that are believed to contribute or protect against it.MethodArticles on burnout (including compassion fatigue and secondary trauma) in psychosocial oncology clinicians were identified by searching PubMed/MEDLINE, EMBASE, PsycINFO, the Cumulative Index to Nursing and Allied Health Literature, and the Web of Science Core Collection.ResultsThirty-eight articles were reviewed at the full-text level, and of those, nine met study inclusion criteria. All were published between 2004 and 2018 and included data from 678 psychosocial clinicians. Quality assessment revealed relatively low risk of bias and high methodological quality. Study composition and sample size varied greatly, and the majority of clinicians were aged between 40 and 59 years. Across studies, 10 different measures were used to assess burnout, secondary traumatic stress, and compassion fatigue, in addition to factors that might impact burnout, including work engagement, meaning, and moral distress. When compared with other medical professionals, psychosocial oncology clinicians endorsed lower levels of burnout.Significance of resultsThis systematic review suggests that psychosocial clinicians are not at increased risk of burnout compared with other health care professionals working in oncology or in mental health. Although the data are quite limited, several factors appear to be associated with less burnout in psychosocial clinicians, including exposure to patient recovery, discussing traumas, less moral distress, and finding meaning in their work. More research using standardized measures of burnout with larger samples of clinicians is needed to examine both prevalence rates and how the experience of burnout changes over time. By virtue of their training, psychosocial clinicians are well placed to support each other and their nursing and medical colleagues.
Anthropocene Politics
Authors: Battistoni Alyssa 
Published: September 2020

AbstractThose for whom the term “Anthropocene” tends to evoke academic faddishness may be surprised to realize that the discourse about it is now two decades old. The term was first proposed in a 2000 paper by the atmospheric chemist Paul Crutzen and biologist Eugene Stoermer to describe the geological epoch in which human activity has come to shape the Earth itself. Since then, the concept has generated a vast amount of scholarly conversation and a wide range of interpretations, often concerning the start date of this new era: Did the “age of man” begin with the use of fire? The development of settled agriculture? The rise of capitalism? European settlement of the Americas? And so on. Although these debates have raged across the humanities and sciences for years, political theorists have largely kept their distance. As the climate crisis worsens, however, many may now be looking to play catch-up. If so, each of the three books under review here holds out the promise of helping us understand the theoretical implications of this epochal transformation.
Validation of a Portuguese Version of the Aspiration Index for Adolescents (AI)
Authors: Costa Mónica , Matos Paula Mena , Mota Catarina Pinheiro 
Published: September 2020

AbstractIntrinsic and extrinsic types of motivation have been widely studied, and their importance on both developmental and educational practices has led to the development of assessment tools. The Aspiration Index scale (AI; Grouzet et al., 2005), which was developed to measure people`s life aspirations, was translated and validated into Portuguese. A sample of 1,359 adolescents, age ranged from 12 to 18 years-old, participated in the present study. Results showed that a factor structure with the eleven subscales of the AI does not fit the data. However we gathered support for a three-factor structure that organized the items in terms of whether aspirations are intrinsically, extrinsically or self-transcendent oriented. Internal consistency and temporal stability yielded good results. The predictive and criterion validities were demonstrated by significant associations with theoretically supported measures of satisfaction with life and father and mother attachment. The multi-group confirmatory factor analysis showed that this structure was invariant across gender. These results suggest that the AI is a reliable measure to assess different types of life aspirations and can be used in future research with adolescents in Portugal.

Published: September 2020

Abstract. Rumination is central to understanding the onset and maintenance of non-suicidal self-injury. Yet, no study has evaluated whether reported differences in rumination between people with and without a history of self-injury represent genuine group differences. The present study reports an investigation into the measurement invariance of three common measures of rumination in university students with and without a history of self-injury (total N = 1,519). Results revealed configural invariance for the Ruminative Responses Scale (RRS), the Ruminative Thought Style Questionnaire (RTSQ), and the Repetitive Thinking Questionnaire (RTQ). Additionally, the RTSQ and RTQ supported metric invariance, while the RRS supported partial metric invariance. Further, the RTQ demonstrated partial scalar invariance while the RTSQ demonstrated full scalar invariance. The current findings suggest that observed differences using the RTSQ and RTQ reflect genuine differences in rumination between people with and without a history of self-injury, while researchers using the RRS are advised to account for differential item functioning.

Published: September 2020

AbstractSperm, which have a vital role in sexual reproduction in the animal kingdom, can display heteromorphism in some species. The regulation of sperm dichotomy remains a longstanding puzzle even though the phenomenon has been widely documented for over a century. Here we use Bombyx mori as a model to study a form of sperm dimorphism (eupyrene and apyrene sperm), which is nearly universal among Lepidoptera. We demonstrate that B. mori Sex-lethal (BmSxl) is crucial for apyrene sperm development, and that B. mori poly(A)-specific ribonuclease-like domain-containing 1 (BmPnldc1) is required for eupyrene sperm development. BmSXL is distributed in the nuclei and cytoplasm of somatic cyst cells in a mesh-like pattern and in the cytoplasm of germ cells enclosed in spermatocysts and sperm bundles. Cytological analyses of dimorphic sperm in BmSxl mutants (∆BmSxl) showed deficient apyrene sperm with abnormal nuclei, as well as loss of motility associated with malformed mitochondrial derivatives. We define the crucial function of apyrene sperm in the process of fertilization as assisting the migration of eupyrene spermatozoa from bursa copulatrix to spermatheca. By contrast, BmPnldc1 deficiency (∆BmPnldc1) caused eupyrene sperm abnormalities and impaired the release of eupyrene sperm bundles during spermiation. Although apyrene or eupyrene sperm defects impaired fertility of the mutated males, double copulation of a wild-type female with ∆BmSxl and ∆BmPnldc1 males could rescue the sterility phenotypes induced by single copulation with either gene-deficient male. Our findings demonstrate the crucial functions of BmSxl and BmPnldc1 in the development of sperm dimorphism and the indispensable roles of nonfertile apyrene sperm in fertilization.
A Bayesian-Inspired Item Response Theory–Based Framework to Produce Very Short Versions of MacArthur–Bates Communicative Development Inventories
Authors: Chai Jun Ho , Lo Chang Huan , Mayor Julien 
Published: September 2020

PurposeThis study introduces a framework to produce very short versions of the MacArthur–Bates Communicative Development Inventories (CDIs) by combining the Bayesian-inspired approach introduced by Mayor and Mani (2019) with an item response theory–based computerized adaptive testing that adapts to the ability of each child, in line with Makransky et al. (2016).MethodWe evaluated the performance of our approach—dynamically selecting maximally informative words from the CDI and combining parental response with prior vocabulary data—by conducting real-data simulations using four CDI versions having varying sample sizes on Wordbank—the online repository of digitalized CDIs: American English (a very large data set), Danish (a large data set), Beijing Mandarin (a medium-sized data set), and Italian (a small data set).ResultsReal-data simulations revealed that correlations exceeding .95 with full CDI administrations were reached with as few as 15 test items, with high levels of reliability, even when languages (e.g., Italian) possessed few digitalized administrations on Wordbank.ConclusionsThe current approach establishes a generic framework that produces very short (less than 20 items) adaptive early vocabulary assessments—hence considerably reducing their administration time. This approach appears to be robust even when CDIs have smaller samples in online repositories, for example, with around 50 samples per month-age.
Alkoholintoxikation bei Kindern und Jugendlichen –
Untersuchung 287 stationärer Fälle Schwere und Besonderheiten
bei Kindern unter 14 Jahren
Authors: Lozada Cesar Armando Quinones , Bartels Marco Baz , Kieslich Matthias 
Published: September 2020

Zusammenfassung
Hintergrund Trotz eines erfreulichen Rückgangs der aufgrund
einer akuten Alkoholintoxikation stationär behandelten
Minderjährigen, stellt der Alkoholkonsum bei Kindern und
Jugendlichen weiterhin eine problematische und besorgniserregende
Angelegenheit dar. Verstärkt wird diese Problematik aufgrund einer
vermutlich ausgeprägteren Symptomatik bei Kindern und Jugendlichen
in Rahmen einer Alkoholintoxikation als Erwachsenen.
Methoden Es wurden insgesamt 287 Fällen von Kindern und
Jugendlichen unter 18 Jahren, die aufgrund einer akuten Alkoholintoxikation
zwischen Januar 2002 und Dezember 2015 stationär in der Kinderklinik
des Universitätsklinikums Frankfurt behandelt wurden, analysiert. Es
erfolgte eine Alterseinteilung in Anlehnung an das Jugendschutzgesetz.
Ergebnisse Die Mehrheit (82/126) der Patienten mit einer
mittleren und schweren Bewusstseinsstörung waren Kinder und
Jugendliche unter 16 Jahre, trotz vergleichbarer, durchschnittlicher
Blutalkoholkonzentration (BAK). Eine präklinische
notärztliche Untersuchung fand bei jüngeren Patienten
deutlich häufiger als bei den älteren (>16 Jahre:
5,8%;<16 Jahre: 13,5% und<14 Jahre:
27,3%) statt. 7,3% der Minderjährigen mussten auf
der Intensivstation behandelt werden, zwei Drittel davon waren
jünger als 16 Jahre. Der Anteil der auf der Intensivstation
behandelten Kinder unter 14 Jahre lag sogar bei 13,6%. Bei 5
Patienten war eine maschinelle Beatmung notwendig, 4 davon waren
jünger als 16 Jahre und 2 davon sogar unter 14 Jahre.
Schlussfolgerungen Minderjährige und speziell Kinder unter 14
Jahre stellen eine besondere Risikogruppe aufgrund einer bedrohlichen
Symptomatik und der Notwendigkeit einer intensiveren medizinischen
Versorgung bei einer Alkoholintoxikation dar. Die konsequente Umsetzung des
Jugendschutzgesetzes, sowie die Entwicklung weitere und Fortführung
der bereits bestehenden Präventionsprogramme, wie das HaLT-Programm,
stellen die wichtigsten Handlungsmaßnahmen für die Zukunft
dar.
COVID-19 in Children and Adolescents with Endocrine Conditions
Authors: Kostopoulou Eirini , Güemes Maria , Shah Pratik 
Published: September 2020

AbstractThe rapid spread of coronavirus disease (COVID-19) worldwide justifies global effort to combat the disease but also the need to review effective preventive strategies and medical management for potentially high-risk populations during the pandemic. Data regarding the COVID-19 manifestations in adults with underlying endocrine conditions, especially diabetes mellitus, are increasingly emerging. Albeit children and adolescents are considered to be affected in a milder manner, paucity of information regarding COVID-19 in children who suffer from endocrinopathies is available. The present review comprehensively collects recommendations issued by various health organizations and endocrine associations for the management of pediatric endocrine conditions during the pandemic. Adhering to the specific “sick day management rules” and undelayed seeking for medical advice are only needed in most of the cases, as the vast majority of children with endocrine disorders do not represent a high-risk population for contamination or severe presentation of COVID-19. Psychological implications in these children and adolescents are also considered.
Ultrasound-guided Dry Needling in Jumper’s Knee: A Case Report
Authors: Cuñado-González Álvaro , Ríos-León Marta 
Published: September 2020

AbstractBackground Jumper’s knee is a highly prevalent tendon condition in volleyball players population. Research on clinical effects of tendon dry needling in jumper’s knee is scarce. Therefore, the aim of this study was to present clinical effects of ultrasound-guided dry needling of quadricipital tendon in a patient with jumper’s knee.Methods A 23-years-old volleyball player, who experienced pain in quadricipital tendon for 5 months, was presented and treated by ultrasound-guided dry needling of quadricipital tendon with one session. Slightly limited knee flexion range of motion, high scores in Visual Analogue Scale (VAS) at rest and during Single-Leg decline Squat test (SLDS) related to high pain intensity, low scores in Victorian Institute of Sport Assessment (VISA-P) scale and Lower Extremity Functional Scale (LEFS) were found. Further examination revealed sensitization of the quadricipital tendon (low pressure pain threshold).Results We found important improvements in VISA-P, LEFS and VAS. Besides, pressure pain threshold and knee flexion during SLDS also showed improvements. Results which were obtained were better in all the variables studied and these recoveries were stable for 6 months.Conclusions Our findings showed improvements in pain and function in medium term and could provide preliminary evidence of beneficial effects of quadricipital tendon dry needling in patients with jumper’s knee. Future studies are needed to clarify our results and compare dry needling with conservative treatments.

Abstract
Background Endoscopic retrograde cholangiopancreatography (ERCP) is often unsuccessful in patients with duodenal stenosis or malignant ampullary infiltration. While endoscopic ultrasound-guided biliary drainage (EUS-BD) has been proposed as an alternative, EUS-guided gallbladder drainage (EUS-GBD) is an attractive option when both approaches fail. We aimed to assess the effectiveness and safety of EUS-GBD as rescue therapy for malignant distal bile duct obstruction.
Methods A multicenter retrospective study was performed on patients with unresectable malignant distal bile duct obstruction who underwent EUS-GBD between 2014 and 2019 after unsuccessful ERCP and EUS-BD. Clinical success was defined as a decrease in serum bilirubin of > 50 % within 2 weeks.
Results 28 patients were included, with a lumen-apposing metal stent used in 26 (93 %) and a self-expandable metal stent in two (7 %). The technical success rate was 100 %. The clinical success rate was 93 %, with an improvement in bilirubin (7.3 [SD 5.4] pre-procedure vs. 2.8 [SD 1.1] post-procedure; P = 0.001). Delayed adverse events included food impaction of the stent (n = 3), with a further two patients developing cholecystitis and bleeding.
Conclusion This study demonstrates the feasibility of gallbladder drainage to relieve malignant distal bile duct obstruction in patients with failed ERCP and EUS-BD.
A Practical Approach for the Transamidation of N,N-Dimethyl Amides with Primary Amines Promoted by Sodium tert-Butoxide under Solvent-Free Conditions

Published: September 2020

AbstractA practical sodium tert-butoxide (NaOtBu)-mediated protocol is disclosed for the transamidation of various N,N-dimethyl amides with primary amines to afford the corresponding amides in moderate to good yields at room temperature under solvent-free conditions. This protocol features a facile work-up procedure and good functional group compatibility, especially for N,N-dimethyl amides with long-chain alkyl groups and heteroatom-containing amines. Notably, a few representative gram-scale reactions proceed smoothly to furnish the desired amides in high yields, which demonstrates the potential of this process for further practical applications. Several control experiments are carried out and a plausible mechanism is provided.

Published: September 2020

AbstractSulfur-containing functional π-conjugated cores play key roles in materials science, mostly due to their unique electrochemical and photophysical properties. Among these, the excellent electron donor tetrathiafulvalene (TTF) has occupied a central position since the emergence of organic electronics. Peripheral C–H modification of this highly useful sulfur-containing motif has resulted in the efficient creation of new molecules that expand the applications of TTFs. This Short Review begins with the development of the palladium-catalyzed direct C–H arylation of TTF. Subsequently, it summarizes the applications of this efficient C–H transformation for the straightforward synthesis of useful TTF derivatives that are employed in a variety of research fields, demonstrating that the development of a new reaction can have a significant impact on chemical science.1	Introduction2	Development of the Palladium-Catalyzed Direct C–H Arylation of TTF3	Synthesis of TTF-Based Tetrabenzoic Acid and Tetrapyridine for MOFs4	Synthesis of TTF-Based Tetrabenzaldehyde and Tetraaniline for COFs5	Tetraarylation of TTFAQ6	Synthesis of Multistage-Redox TTF Derivatives7	Miscellaneous Examples8	Conclusions
