Inter and intra-annual links between climate, tree growth and NDVI: improving the resolution of drought proxies in conifer forests
Authors: Pompa-García Marín , Camarero J. Julio , Colangelo Michele , González-Cásares Marcos
Published: July 2021

The inter- and intra-annual variability in radial growth reflects responses to climatic variability and water shortage, especially in areas subjected to seasonal drought. However, it is unknown how this variability is related to forest productivity, which can be assessed by measuring changes in canopy greenness and cover through remote sensing products as the Normalized Difference Vegetation Index (NDVI). We combine xylogenesis with measurements of inter-annual changes in seasonal wood production (earlywood width, adjusted latewood width) and NDVI to improve the understanding of climate and drought impacts on growth and forest productivity in a Pinus teocote stand located in northern Mexico. Cambial dynamics accelerated in March and a high production of radially enlarging and thickening tracheids were observed from April to October and from June to October, respectively. Tracheid maturation was very active in October when latewood production peaked. Wet conditions in winter-spring and summer-autumn enhanced earlywood and latewood production, respectively. Earlywood and latewood were constrained by long (4–10 months) and short (2–3 months) droughts, respectively. The earlywood production depended on April soil moisture, which agrees with the peak of radially enlarging tracheid production found during that month. Aligning drought proxies at inter- and intra-annual scales by using growth and productivity measures improves our understanding of conifer forest responses to water shortage.
Universal access: user needs for immersive captioning
Authors: Hughes Chris. J.
Published: July 2021

This article focuses on building a prototyping for immersive captioning following a user-centric approach. This methodology is characterised by following a bottom-up approach, where usability and user needs are at the heart of the development. Recent research on user requirements for captioning in immersive environments has shown that there is both a need for improvement and a wealth of research opportunities. The final aim is to identify how to display captions for an optimal viewing experience. This work began four years ago with some partial findings. We build from the lessons learnt, focussing on the user-centric design requirements cornerstone: prototyping. Our prototype framework integrates methods used in existing solutions aiming at instant contrast-and-compare functionalities. The first part of the article presents the state of the art for user requirements identifying the reasons behind the development of the prototyping framework. The second part of the article describes the two-stage framework development. The initial framework concept answered to the challenges resulting from the previous research. As soon as the first framework was developed, it became obvious that a second improved solution was required, almost as a showcase on how ideas can quickly be implemented for user testing, and for users to elicit requirements and creative solutions. The article finishes with a list of functionalities, resulting in new caption modes, and the opportunity of becoming a comprehensive immersive captions testbed, where tools such as eye-tracking, or physiological testing devices could be testing captions across any device with a web browser.

Alkaloids are a structurally complex group of natural products that have a diverse range of biological activities and significant therapeutic applications. In this study, we examined the acute, anxiolytic-like effects of nicotinic acetylcholine receptor (nAChR)-activating alkaloids with reported neuropharmacological effects but whose effects on anxiety are less well understood. Because α4β2 nAChRs can regulate anxiety, we first demonstrated the functional activities of alkaloids on these receptors in vitro. Their effects on anxiety-like behavior in zebrafish were then examined using the zebrafish novel tank test (NTT). The NTT is a relatively high-throughput behavioral paradigm that takes advantage of the natural tendency of fish to dive down when stressed or anxious. We report for the first time that cotinine, anatabine, and methylanatabine may suppress this anxiety-driven zebrafish behavior after a single 20-min treatment. Effective concentrations of these alkaloids were well above the concentrations naturally found in plants and the concentrations needed to induce anxiolytic-like effect by nicotine. These alkaloids showed good receptor interactions at the α4β2 nAChR agonist site as demonstrated by in vitro binding and in silico docking model, although somewhat weaker than that for nicotine. Minimal or no significant effect of other compounds may have been due to low bioavailability of these compounds in the brain, which is supported by the in silico prediction of blood–brain barrier permeability. Taken together, our findings indicate that nicotine, although not risk-free, is the most potent anxiolytic-like alkaloid tested in this study, and other natural alkaloids may regulate anxiety as well.
Effect of Ausforming on the Macro- and Micro-texture of Bainitic Microstructures

Published: July 2021

The reason why variant selection phenomena occur in ausforming treatments is still not known. For that reason, in this work, the effect of compressive deformation on the macro and micro-texture of a bainitic microstructure was analyzed in a medium-carbon high-silicon steel subjected to ausforming treatments, where deformation was applied at 520 °C, 400 °C and 300 °C. The as-received material presented a very weak

fiber texture present in the prior austenite. The intensity of this transformation texture was more pronounced as the deformation temperature decreased. Also, variant selection was examined at different scales by combining Electron-Backscattered Diffraction and X-ray Diffraction. The quantification of the fraction of crystallographic variants under certain conventions for every condition revealed variant selection in samples subjected to ausforming treatments, where these phenomena were stronger as the deformation temperature was lower. Finally, some of the theories proposed so far to explain these variant selection phenomena were tested, showing that variants were not selected based on their Bain group and that their selection can be better described in terms of their belonging to packets, if these are defined according to a global reference frame. This suggests that the phenomena might have to do with the effect of deformation mechanisms on the prior austenite.
Improving Diagnostic Workup Following Traumatic Spinal Cord Injury: Advances in Biomarkers
Authors: Schading Simon , Emmenegger Tim M. , Freund Patrick
Published: July 2021

Purpose of Review

Traumatic spinal cord injury (SCI) is a life-changing event with drastic implications for patients due to sensorimotor impairment and autonomous dysfunction. Current clinical evaluations focus on the assessment of injury level and severity using standardized neurological examinations. However, they fail to predict individual trajectories of recovery, which highlights the need for the development of advanced diagnostics. This narrative review identifies recent advances in the search of clinically relevant biomarkers in the field of SCI.

Recent Findings

Advanced neuroimaging and molecular biomarkers sensitive to the disease processes initiated by the SCI have been identified. These biomarkers range from advanced neuroimaging techniques, neurophysiological readouts, and molecular biomarkers identifying the concentrations of several proteins in blood and CSF samples. Some of these biomarkers improve current prediction models based on clinical readouts. Validation with larger patient cohorts is warranted.

Several biomarkers have been identified—ranging from imaging to molecular markers—that could serve as advanced diagnostic and hence supplement current clinical assessments.
Candida gut colonization, yeast species distribution, and biofilm production in Clostridioides difficile infected patients: a comparison between three populations in two different time periods
Authors: Brunetti Grazia , Giuliani Alessandro , Navazio Anna Sara , Paradisi Camilla , Raponi Flavia , Conti Libenzio Adrian , Raponi Giammarco
Published: July 2021

Candida gut colonization and yeast biofilm production capacity were investigated, by means of XTT reduction assay, in Clostridioides difficile infected (CDI) patients, in non-CDI diarrheic patients, and in healthy donors in two different time periods (2013–2015 and 2018–2019 respectively). Candida gut colonization was significantly (p < 0.001) associated to C. difficile infection, and to patients infected with hypervirulent C. difficile strains bearing the tcdC deletion at nucleotide 117 (p = 0.0003). Although there was not a prevalent yeast species in CDI patients, C. albicans was the species significantly (p < 0.001) associated to both the infections sustained by the non-hypervirulent C. difficile strains and those caused by the hypervirulent strain (p = 0.001). The biofilm production by the yeasts isolated from the CDI patients and from non-CDI diarrheic patients did not differ significantly. However, a significantly (p = 0.007) higher biofilm production was observed in the Candida strains, particularly C. albicans, isolated from healthy donors compared to that of the yeasts cultured from CDI patients. Seasonal occurrence was observed in the isolation rate of CDI and non-CDI diarrheic cases (p = 0.0019), peaking in winter for CDI patients and in spring for non-CDI diarrheic patients. Furthermore, seasonality emerged in the gut colonization by Candida of CDI patients in the winter. It seems, therefore, that the reduced capacity of biofilm production by Candida strains isolated from CDI patients might have a role in the development of C. difficile infection, probably facilitating the spread of the bacteria into the gut thus amplifying their pathogenic action.

Authors: García-Gómez Borja , Aversa Antonio , Alonso-Isa Manuel , Parnham Arie , Serefoglu Ege Can , Corona Giovanni , Bettocchi Carlo , Reisman Yacov , Skrodzka Marta , Romero-Otero Javier
Published: July 2021

Introduction

Penile traction therapy (PTT) aims to non-surgically reduce curvature, enhance girth, and recover lost length. Available clinical practice guidelines however lack clear recommendations regarding their use.

Aim

To present a comprehensive review and recommendation regarding the available evidence to the use of PTT in Peyronie's disease (PD).

Methods

A systematic literature search was performed on Pubmed and Medline for relevant studies from all times until 2019. Studies of PTT (monotherapy and in combination) in patients with PD with any documented degree of curvature and in either the acute or chronic phase of the disease were included. Full texts not published in English language were excluded.

Main outcomes measures

Several scenarios, including preclinical data have been investigated. For each topic covered evidence was analyzed and expert opinion was stated.

Results

The paucity of high-level studies precluded any strong recommendations, however, specific statements on this topic, summarizing the ESSM position, were provided. The available data about the use of PTT in PD are still poor, and the impact of this therapy for the treatment of PD has not been clearly stablished. Available data in the clinical setting are still poor, and the impact of these devices on PD evolution has not been clearly established.

Conclusion

PTT seems to be a valid treatment option for PD, although there is not enough evidence to give any definitive recommendation in any clinical scenario. García-Gómez B, Aversa A, Alonso-Isa M et al.

Sexual History Taking: Perspectives on Doctor-Patient Interactions During Routine Consultations in Rural Primary Care in South Africa
Authors: Pretorius Deidré , Couper Ian , Mlambo Motlatso
Published: July 2021

Background

Sexual history taking for risk behavior contributes to improving health outcomes in primary care. Giving the high numbers of people living with AIDS, every patient in South Africa should be offered an HIV test, which implies that a comprehensive sexual history must be taken.

Aim

To describe the optimal consultation process, as well as associated factors and skills required to improve disclosure of sexual health issues during a clinical encounter with a doctor in primary health care settings in North West province, South Africa.

Methods

This qualitative study, based on grounded theory, involved the video-recording of 151 consultations of adult patients living primarily with hypertension and diabetes. This article reports on the 5 consultations where some form of sexual history taking was observed. Patient consultations were analyzed thematically, which entailed open coding, followed by focused and verbatim coding using MaxQDA 2018 software. Confirmability was ensured by 2 generalist doctors, a public health specialist and the study supervisors.

Main Outcome Measure

Sexual history was not taken and patients living with sexual dysfunction were missed. If patients understand how disease and medication contribute to their sexual wellbeing, this may change their perceptions of the illness and adherence patterns.

Results

Sexual history was taken in 5 (3%) out of 151 consultations. Three themes emerged from these 5 consultations. In the patient-doctor relationship theme, patients experienced paternalism and a lack of warmth and respect. The consultation context theme included the seating arrangements, ineffective use of time, and privacy challenges due to interruptions and translators. Theme 3, consultation content, dealt with poor coverage of the components of the sexual health history.

Conclusion

Overall, sexual dysfunction in patients was totally overlooked and risk for HIV was not explored, which had a negative effect on patients’ quality of life and long-term health outcomes. The study provided detailed information on the complexity of sexual history taking during a routine consultation and is relevant to primary health care in a rural setting.

Earth Detox
Authors: Cribb Julian
Published: July 2021

Every person on our home planet is affected by a worldwide deluge of man-made chemicals and pollutants - most of which have never been tested for safety. Our chemical emissions are six times larger than our total greenhouse gas emissions. They are in our food, our water, the air we breathe, our homes and workplaces, the things we use each day. This universal poisoning affects our minds, our bodies, our genes, our grandkids, and all life on Earth. Julian Cribb describes the full scale of the chemical catastrophe we have unleashed. He proposes a new Human Right - not to be poisoned. He maps an empowering and hopeful way forward: to rid our planet of these toxins and return Earth to the clean, healthy condition which our forebears enjoyed, and our grandchildren should too.
How Many Dates Do I Need?
Authors: Holland-Lulewicz Jacob , Ritchison Brandon T.
Published: July 2021

As the use of large-scale radiocarbon datasets becomes more common and applications of Bayesian chronological modeling become a standard aspect of archaeological practice, it is imperative that we grow a community of both effective users and consumers. Indeed, research proposals and publications now routinely employ Bayesian chronological modeling to estimate age ranges such as statistically informed starts, ends, and spans of archaeological phenomena. Although advances in interpretive techniques have been widely adopted, sampling strategies and determinations of appropriate sample sizes for radiocarbon data remain generally underdeveloped. As chronological models are only as robust as the information we feed into them, formal approaches to assessing the validity of model criteria and the appropriate number of radiocarbon dates deserve attention. In this article, through a series of commonly encountered scenarios, we present easy-to-follow instructions for running simulations that should be used to inform the design and construction of chronological models.
Population-based surveillance of medical tourism among US residents from 11 states and territories: Findings from the Behavioral Risk Factor Surveillance System
Authors: Stoney Rhett J. , Kozarsky Phyllis E. , Walker Allison T. , Gaines Joanna L.
Published: July 2021

Objective:

To describe medical tourism among a subset of US residents; identify possible indicators for medical tourism.

Methods:

The US Centers for Disease Control and Prevention collaborated with 11 states and territories to ask 6 questions about medical tourism, using the Behavioral Risk Factor Surveillance System. Data collected from January 1, 2016, through December 31, 2016, included whether respondents traveled internationally for preplanned care, travel reasons and destinations, procedures received, and occurrence and treatment of complications. A descriptive analysis of demographics, socioeconomic status and health access variables was performed, and a regression model with a log-link function and Poisson distribution was used to estimate prevalence ratios (PR) for medical tourism.

Results:

Of 93,492 respondents, 517 (0.55%) traveled internationally during the previous year for care. Mexico was the most common destination (41% of trips). Dentistry accounted for 55% of treatments. Complications from care received abroad were reported by 5% of medical tourists; 67% sought care upon returning to the United States. The prevalence of medical tourism was 1.32% (95% CI, 1.00–1.64). The prevalence of medical tourism was higher in Hispanics and non-whites (PR, 3.97; 95% CI, 2.48–6.32) and higher among those without current health insurance (PR, 2.70; 95% CI, 1.69–4.34).

Conclusions:

This is the largest collection of population-based surveillance data describing medical tourism among US residents from multiple states and territories. Understanding the demographic and socioeconomic factors associated with medical tourism can inform evidence-based recommendations for travelers and clinicians who may advise or care for these individuals before, during, or after travel.
A contingency perspective on employees' voice behavior in response to career plateau beliefs
Authors: De Clercq Dirk
Published: July 2021

With a conceptual basis in conservation of resources theory, this paper investigates the relationship between employees' career plateau beliefs and their voice behavior, using parallel arguments that reflect resource-conservation versus resource-acquisition logics. The career plateau beliefs–voice behavior link, whether negative or positive, might be invigorated when employees encounter adversity in the workplace, such as due to work pressures (work overload and work–family conflict) or because of how their organization makes decisions (organizational politics and organizational underperformance). Survey data from employees in the Canadian information technology sector provide empirical support for the resource-acquisition logic: career plateau beliefs enhance employees' propensity to offer ideas for organizational improvement, particularly if they suffer from excessive workloads or conflicting work–family demands, perceive organizational decision making as political, and are unhappy about their organization's performance. These novel insights point to the critical role of a stagnated career in triggering, instead of dampening, proactive voice behaviors.
De-Linking From Western Epistemologies: UsingGuanxi-Type Relationships to Attract and Retain Hotel Guests in the Middle East
Authors: Shaalan Ahmed , Eid Riyad , Tourky Marwa
Published: July 2021

Relationships are widely recognized as key to business success in the form of both informal interpersonal networks and formal organizational relationships. While Chinese personal networks (guanxi) have attracted scholars’ interest, the concept has not been fully investigated or understood in other contexts, especially the Middle East, where personal networks fulfill some of the same roles. The underlying socio-cultural formulae of the distinctive cultural dimensions that influence relationship formation in the Middle East also remain under-explored. This research therefore investigates the dimensions ofguanxi-type relationships in the Middle East and introduces a new model integrating these relationships into the existing relationship marketing framework, enabling firms to harness personal networks for organizational gain, in turn generating customer satisfaction and retention. Using empirical data from a survey of 637 hotel guests in 17 countries – drawn from a unique target population of guests introduced to Middle Eastern hotels via personal relationships – we show howguanxi-type relationships influence organizational relationships and improve satisfaction and retention. Our significant contributions to theory and practice include extending a holistic understanding ofguanxi, enhancing knowledge of its dimensions in the Middle East, and providing managers with clear evidence for a hybrid system ofguanxi-type and organizational relationships.
Bargaining outcomes and success in EU economic governance reforms
Authors: Franchino Fabio , Mariotto Camilla
Published: July 2021

We assess the accuracy of procedural and bargaining models in predicting the outcomes of the reforms of the economic governance of the European Union (EU) that took place between 1997 and 2013. These negotiations were characterized by high costs of failure. We confirm the accuracy and robustness of the compromise model, but a procedural model with a costly reference point performs well, indicating that misestimation of the no-agreement cost may be a reason for its commonly reported poorer accuracy. However, this model is more sensitive to measurement errors. We also show how both models contribute to understanding bargaining success and how the conditional influence of the European Parliament should not be ignored. We conclude by discussing the implications of these results for our understanding of the EU.
The Unbearable Lightness of Trust: Trade, conviviality, and the life-world of Indian export agents in Yiwu, China
Authors: Osella Filippo
Published: July 2021

Drawing on ethnographic data collected in China, the United Arab Emirates (UAE), and India, this article explores the life-world and practices of small-scale Indian export agents based in Yiwu, China, the world centre for the export of small commodities. It shows that in a market overdetermined by fast-moving goods, short-term gains, and low margins, export agents have to steer their way between acting with extreme caution or taking risks with their clients and suppliers. These apparently contradictory dispositions or orientations are negotiated by the judicious exercise of mistrust and suspicion. The article suggests not only that mistrust is valued and cultivated as an indispensable practical resource for success in Yiwu's export trade, but that contingent relations of trust between market players emerge at the interstices of a generalized mutual mistrust, via the mobilization of practices of hospitality, commensality, and masculine conviviality. Indeed, feelings of amity and mutuality elicited by the performance of modalities of social intimacy become the affective terrain upon which divergent economic interests might be reconciled and taken forward. That is, mistrust might not lead to generalized distrust, instead a situational or contingent trust might actually emerge through the judicious exercise of mistrust.
Labour market marginalisation in young adults diagnosed with attention-deficit hyperactivity disorder (ADHD): a population-based longitudinal cohort study in Sweden
Authors: Helgesson Magnus , Björkenstam Emma , Rahman Syed , Gustafsson Klas , Taipale Heidi , Tanskanen Antti , Ekselius Lisa , Mittendorfer-Rutz Ellenor
Published: July 2021

Background

The objective of this population-based register study was (1) to investigate the association between young adults diagnosed with attention-deficit/hyperactivity disorder (ADHD) and subsequent labour market marginalisation (LMM) in two comparison groups, i.e. matched young adults from the general population without ADHD and unaffected siblings to persons with ADHD and (2) to assess the role of comorbid disorders.

Methods

This study included all young adults in Sweden, aged 19–29 years, with an incident diagnosis of ADHD 2006–2011 (n = 9718). Crude and multivariate sex-stratified hazard ratios (HRs) with 95% confidence intervals (CIs) were measured 5 years after the diagnosis of ADHD for the risk of disability pension, long-term sickness absence (SA) (>90 days), long-term unemployment (>180 days) and a combined measure of all three in young adults with ADHD compared to their siblings without ADHD and a matched comparison group.

Results

In the adjusted analyses young adults with ADHD had a 10-fold higher risk of disability pension (HR = 10.2; CI 9.3–11.2), a nearly three-fold higher risk of long-term SA (HR = 2.7; CI 2.5–2.8) and a 70% higher risk of long-term unemployment (HR = 1.7; CI 1.6–1.8) compared to the matched comparison group. The risk estimates were lower compared to siblings for disability pension (HR = 9.0; CI 6.6–12.3) and long-term SA (HR = 2.5; CI 2.1–3.1) but higher in the long-term unemployed (HR = 1.9; CI 1.6–2.1). Comorbid disorders explained about one-third of the association between ADHD and disability pension, but less regarding SA and long-term unemployment.

Conclusions

Young adults with ADHD have a high risk for different measures of LMM and comorbidities explain only a small proportion of this relationship.
Psychiatric disorders in China: strengths and challenges of contemporary research and clinical services
Authors: Chang Xiao , Gong Qiyong , Li Chunbo , Yue Weihua , Yu Xin , Yao Shuqiao , Feng Jianfeng
Published: July 2021

China accounts for 17% of the global disease burden attributable to mental, neurological and substance use disorders. As a country undergoing profound societal change, China faces growing challenges to reduce the disease burden caused by psychiatric disorders. In this review, we aim to present an overview of progress in neuroscience research and clinical services for psychiatric disorders in China during the past three decades, analysing contributing factors and potential challenges to the field development. We first review studies in the epidemiological, genetic and neuroimaging fields as examples to illustrate a growing contribution of studies from China to the neuroscience research. Next, we introduce large-scale, open-access imaging genetic cohorts and recently initiated brain banks in China as platforms to study healthy brain functions and brain disorders. Then, we show progress in clinical services, including an integration of hospital and community-based healthcare systems and early intervention schemes. We finally discuss opportunities and existing challenges: achievements in research and clinical services are indispensable to the growing funding investment and continued engagement in international collaborations. The unique aspect of traditional Chinese medicine may provide insights to develop a novel treatment for psychiatric disorders. Yet obstacles still remain to promote research quality and to provide ubiquitous clinical services to vulnerable populations. Taken together, we expect to see a sustained advancement in psychiatric research and healthcare system in China. These achievements will contribute to the global efforts to realize good physical, mental and social well-being for all individuals.
Stochastic properties of generalized finite α-mixtures
Authors: Shojaee Omid , Asadi Majid , Finkelstein Maxim
Published: July 2021

Most of the real-life populations are heterogeneous and homogeneity is often just a simplifying assumption for the relevant statistical analysis. Mixtures of lifetime distributions that correspond to homogeneous subpopulations were intensively studied in the literature. Various distributional and stochastic properties of finite and continuous mixtures were discussed. In this paper, following recent publications, we develop further a mixture concept in the form of the generalized α-mixtures that include all mixture models that are widely explored in the literature. We study some main stochastic properties of the suggested mixture model, that is, aging and appropriate stochastic comparisons. Some relevant examples and counterexamples are given to illustrate our findings.
A trustful monad for axiomatic reasoning with probability and nondeterminism
Authors: AFFELDT REYNALD , GARRIGUE JACQUES , NOWAK DAVID , SAIKAWA TAKAFUMI
Published: July 2021

The algebraic properties of the combination of probabilistic choice and nondeterministic choice have long been a research topic in program semantics. This paper explains a formalization in the Coq proof assistant of a monad equipped with both choices: the geometrically convex monad. This formalization has an immediate application: it provides a model for a monad that implements a nontrivial interface, which allows for proofs by equational reasoning using probabilistic and nondeterministic effects. We explain the technical choices we made to go from the literature to a complete Coq formalization, from which we identify reusable theories about mathematical structures such as convex spaces and concrete categories, and that we integrate in a framework for monadic equational reasoning.
International banking and financial fragility: the role of regulation in Brazil and Mexico, 1967–1982
Authors: Alvarez Sebastian
Published: July 2021

The shortcomings and potential dangers of international financial flows for the health and stability of domestic banking systems in developing countries have been copiously discussed over the last decades. While the importance of capital controls and regulation as determining factors has been widely emphasised, the extent to which these policies work in episodes of financial crisis is still a matter of debate. This article examines the relationship between supervisory frameworks and banking fragility in Mexico and Brazil in the wake of the international debt crisis of 1982. It shows that the model of international banking intermediation that evolved out of the stringent capital mobility system in Brazil was considerably less vulnerable to crisis than in Mexico, which had a more lightly regulated regime. These findings provide insights into historical debates about the implications of prudential regulation and capital controls for the development and expansion of foreign finance, and whether the risks underlying international banking are necessarily inherent in the process of financial globalisation.
Cardiac implications of multisystem inflammatory syndrome associated with COVID-19 in children under the age of 5 years
Authors: Rakha Shaimaa , Sobh Ali , Hager Amira H. , Hafez Mona , Alsawah Gehan A. , Abuelkheir Mohamed Magdi , Zeid Mayada Sabry , Nahas Mohamed , Elmarsafawy Hala
Published: July 2021

Background:

Coronavirus disease 2019 (COVID-19) is responsible for significant lung disease in adults. Despite mild manifestations in most children, multisystem inflammatory syndrome (MIS-C) associated with COVID-19 is well described in older children with cardiac manifestations. However, MIS-C-related cardiac manifestations are not as well described in younger children.

Methods:

The study is a retrospective analysis of MIS-C patients under the age of 5 years admitted between May and November 2020 to a single centre. Included cases fulfilled the case definition of MIS-C according to Royal College of Pediatrics and Child Health criteria with laboratory, electrocardiogram, or echocardiographic evidence of cardiac disease. Collected data included patients’ demographics, laboratory results, echocardiographic findings, management, and outcomes.

Results:

Out of 16 MIS-C cases under 5 years of age, 10 (62.5%) had cardiac manifestations with a median age of 12 months, 9 (90%) were previously healthy. Cardiac manifestations included coronary arterial aneurysms or ectasia in five (50%) cases, two (20%) with isolated myopericarditis, coronary ectasia with myocarditis in two (20%), and supraventricular tachycardia in one (10%). Intravenous immunoglobulins were given in all cases with coronary involvement or myocarditis. The median duration of hospitalisation was 7 (6–14) days; two (20%) cases with cardiac disease were mechanically ventilated and mortality in MIS-C cases below 5 years was 12.5%. Normalisation of systolic function occurred in half of the affected cases within 1 week and reached 100% by 30 days of follow-up.

Conclusions:

MIS-C associated with SARS-CoV-2 has a high possibility of serious associated cardiac manifestations in children under the age of 5 years with mortality and/or long-term morbidities such as coronary aneurysms even in previously healthy children.
Female Sex as a Protective Factor in the Effects of Chronic Cannabis Use on Verbal Learning and Memory
Authors: Hirst Rayna , Vaughn Dylan , Arastu Sana , Deneen Aubrey , Pilavjian Haig
Published: July 2021

Objective:

The variability of findings in studies examining the effects of chronic cannabis use on neuropsychological functioning highlights the importance of examining contributing factors. Few studies examine the role of sex in the relationship between cannabis and neuropsychological functioning, despite known neurobiological structural differences between males and females. This study examined whether males and females experience differential cognitive effects of chronic cannabis use.

Method:

Chronic cannabis users (3+ days per week for >12 months, n = 110, 72% male) and non-users (n = 71, 39% male) completed a neuropsychological test battery. Two multivariate analyses of covariance (MANCOVAs) examined for sex differences in performance within users and non-users on neuropsychological tests, controlling for potential confounding variables. Bonferroni corrections were applied to adjust for multiple comparisons.

Results:

Male and female cannabis users did not differ in cannabis use variables. Female cannabis users performed better than males on multiple subtests of the California Verbal Learning Test-II (CVLT-II), a verbal learning and memory test. Male cannabis users performed better than female users on Trial 1 of the CVLT-II (p = .002), and Trail Making Test B (p = .001), which measure attention and cognitive flexibility, respectively. Non-user males and females performed comparably, with the exception of Trail Making Test B (p = .001).

Conclusions:

Results suggest that chronic cannabis use differentially impacts males and females, with females exhibiting better verbal learning and memory despite males demonstrating better attention and cognitive flexibility. Further research is needed to understand the potential protective mechanism of female sex on learning and memory effects of cannabis use.
Initiation of Moderately Frequent Cannabis use in Adolescence and Young Adulthood is Associated with Declines in Verbal Learning and Memory: A Longitudinal Comparison of Pre- versus Post-Initiation Cognitive Performance
Authors: Ajmera Nirvi , Collins Paul F. , Weiss Hannah , Luciana Monica
Published: July 2021

Objective:

Cannabis use is associated with relative cognitive weaknesses as observed by cross-sectional as well as longitudinal research. Longitudinal studies, controlling for relevant confounds, are necessary to differentiate premorbid from post-initiation contributions to these effects.

Methods:

We followed a sample of adolescents and young adults across ten years. Participants provided neurocognitive data and substance use information at two-year intervals. Participants who initiated cannabis and/or alcohol use were identified (n = 86) and split into alcohol-only initiators (n = 39) and infrequent (n = 29) and moderately frequent (n = 18) cannabis initiators. Participants completed the Rey Auditory Verbal Learning Task (RAVLT) and the Iowa Gambling Task (IGT). Group differences before and after substance use initiation and the extent to which alcohol, nicotine, and cannabis use frequencies contributed to cognitive functions over time were examined.

Results:

After controlling for parental education, RAVLT new learning was worse in moderately frequent cannabis users prior to use initiation. RAVLT total learning and delayed recall showed significant declines from pre- to post-initiation in moderately frequent cannabis users. Regression analyses confirmed that frequencies of cannabis, but not alcohol, use contributed to post-initiation variations. Nicotine use showed an independent negative association with delayed memory. Findings for the IGT were not significant.

Conclusions:

Verbal learning and memory may be disrupted following the initiation of moderately frequent cannabis use while decreased new learning may represent a premorbid liability. Our use of a control group of alcohol-only users adds interpretive clarity to the findings and suggests that future studies should carefully control for comorbid substance use.
Has international CPI inflation comovement strengthened since the global financial crisis?
Authors: Shin Inseok , Kang Kyu Ho
Published: July 2021

This study detects a structural break in international consumer price index (CPI) inflation comovement. We estimate the dynamic common factor models with unknown breakpoints of cross-country inflation rates and global price index of all commodities. We identify two global factors from the models: a commodity global factor and a noncommodity global factor. The former is a common factor between national inflation rates and commodity price index growth; the latter is a common factor among national inflation rates. The estimation of 29 countries’ quarterly CPI inflation data from 2001:Q1 to 2018:Q2 shows a one-time break in cross-country inflation dynamics in 2008:Q4. Thereafter, the importance of global factors in explaining the national inflation rates is remarkably increased. Furthermore, the increased global inflation synchronization is mainly driven by the larger role of the noncommodity global factor rather than that of the commodity global factor.
The Association Between Body Mass Index, Emotional Eating and Perceived Stress during COVID-19 Partial Quarantine in Healthy Adults
Authors: Barcın-Güzeldere Hatice Kübra , Devrim-Lanpir Aslı

Objective:

We investigated emotional eating behaviours and perceived stress during COVID-19 partial quarantine according to BMI levels in healthy adults.

Design:

Cross-sectional study.

Setting:

An online survey including demographic variables, eating attitude-related questions, Emotional Eater Questionnaire (EEQ) and Perceived Stress Scale-14 (PSS-14) was sent via online data collection platform. Self-reported weight, height and weight changes during the quarantine were also collected.

Participants:

A total of 506 people aged between 20–65 years who were partially quarantined due to COVID-19 participated in this study.

Results:

BMI was positively correlated with EEQ (r 0 ·205, P = 0·001). However, BMI was negatively linked with PSS-14 during COVID-19 (r -0·125, P = 0·001), indicating that participants with lower BMI had higher perceived stress during COVID-19. Participants gained weight during the lockdown situation (+1·20 ± 1·70 kg in men; +0·91 ± 1·40 kg in women). EEQ and PSS-14 scores of women found to be significantly higher than men (9·39 ± 5·37 in men v. 11·17 ± 5·85 in women for EEQ; 24·67 ± 8·32 in men v. 27·99 ± 7·34 in women for PSS-14). Obese participants consumed sweetened and carbonated drinks two-fold more in those compared with other participants.

Conclusion:

These findings suggest that partial quarantine may be closely related to emotional eating and weight gain, and participants with higher BMI showed more emotional eating behaviours. Therefore, certain precautions should be considered beforehand in order not to cause long-term eating disorder problems.
Kant’s Original Space and Time as Mere Grounds for Possibilities
Authors: Raysmith Thomas
Published: July 2021

In the Critique of Pure Reason Kant appears to make incompatible claims regarding the unitary natures of what he takes to be our a priori representations of space and time. I argue that these representations are unitary independently of all synthesis and explain how this avoids problems encountered by other positions regarding the Transcendental Deduction and its relation to the Transcendental Aesthetic in that work. Central is the claim that these representations (1) contain, when characterized as intuitions and considered as prior to any affections of sensibility, only an infinitude of merely possible finite spatial and temporal representations, and (2) are representations that are merely transcendental grounds for the possibilities for receiving or generating finite representations in sensibility that are determined (immediately, in the case of reception) by means of syntheses that accord with the categories.
Attitudes and applications of chairwork amongst CBT therapists: a preliminary survey
Authors: Pugh Matthew , Bell Tobyn , Waller Glenn , Petrova Emma
Published: July 2021

Chairwork refers to a collection of experiential interventions which utilise chairs, their positioning, movement, and dialogue to facilitate therapeutic change. Chair-based methods are used in several models of psychotherapy, including cognitive behavioural therapy (CBT). However, little is known about cognitive behavioural therapists’ use and attitudes towards chairwork. A mixed methods survey was conducted of 102 therapists who provided CBT. Overall, training in chairwork was weak amongst CBT therapists (35%). Quantitative results indicated that most therapists perceived chairwork to be clinically effective and consistent with the cognitive behavioural model, but did not feel competent using these methods. Perceived competence was highest amongst therapists who had been trained in chairwork and practised it frequently, but was unrelated to CBT accreditation or clinical experience. Qualitative feedback identified a number of factors that encouraged the use of chairwork (e.g. overcoming limitations associated with verbal restructuring methods), as well as inhibitors (e.g. therapist anxiety and limited access to training). These preliminary findings highlight a need for further research relating to cognitive behavioural chairwork and suggest that increased training in experiential interventions could go some way towards improving outcomes in CBT.

Key learning aims

As a result of reading this paper, readers should:

(1)

Understand cognitive behavioural therapists’ attitudes towards chairwork.

(2)

Appreciate therapists’ anxiety and avoidance in relation to chairwork.

(3)

Identify the key factors that facilitate or inhibit the use of cognitive behavioural chairwork.
Breaching Boundaries in Muslim and Christian Tourism from Indonesia to Israel and Palestine
Authors: Lücking Mirjam
Published: July 2021

Studies on tourism and pilgrimage show that spatial mobility, including transregional travel, mostly confirms and strengthens tourists’ and pilgrims’ social identities and symbolic boundaries between Self and Other. However, in guided religious package tours from Indonesia to Israel and Palestine, experiences with spatial boundaries do affect the Muslim and Christian pilgrims, adding more nuances to socio-cultural boundary-making. This complex making and breaching of boundaries relates to inner-Indonesian religious dynamics. Among both Muslim and Christian Indonesians, references to the Middle East express not only transregional solidarity but also multifarious orientations in inter and intra-religious relations within Indonesia. Among Indonesian Muslims, some orthodox Muslims’ orientations towards the Middle East as the birthplace of Islam are contested but also combined with indigenous Islamic traditions. Similar to these intra-Muslim frictions, members of Indonesia's Christian minority experience fissures in the expressions of local and global Christian identities. This article analyses how symbolic, social, and spatial boundaries are maintained and breached in transregional tourism from Indonesia to the Middle East.
A New Clustering Algorithm Toward Building Segmentation From Aerial Images by Utilizing RGB‐Component Differences

For the image segmentation task, deep features‐based deep learning methods have strict data requirements on the quality and quantity, which limits their application in irregular scenes, such as the villages subjected to geological hazards in the complex mountains. However, traditional algorithms with shallow and middle features are unable to utilize the complex information of unmanned aerial vehicle (UAV) remote sensing images effectively. To address this issue, we proposed a new image segmentation algorithm by using the RGB component difference clustering (RGBCDC). In this method, after dimensionality reduction of RGB color space from three dimensions to two dimensions, the distance between similar objects would be diminished and the distance between disturbance areas would be enlarged. Two different UAV data sets (3,000 in total) have been used to compare the proposed algorithm with the traditional segmentation algorithms and the deep learning‐based methods. Results show that the average pixel accuracy is 13.11%, 11.86%, 13.84%, 8.00%, and 9.86% higher than Octree Quantization clustering algorithm, Region Growing algorithm, Watershed algorithm, K‐Means algorithm, and SLIC superpixel segmentation algorithm, respectively. When facing insufficient samples, the new method performed better than deep learning algorithms, such as Deeplabv3, PSPnet, UNET, and UISBB. In general, the proposed algorithm for building segmentation shows a better potential for use in uncommon situations, especially for rapid emergency rescue after serious mountain hazards.
