Exercise and Cardiovascular Disease Risk Factors in Children and Adolescents With Obesity: A Systematic Review With Meta-Analysis of Randomized Controlled Trials
Authors: Kelley George A. , Kelley Kristi S. , Pate Russell R.
Published: February 2021

The purpose of this study was to examine the effects of exercise on cardiovascular disease (CVD) risk factors in children and adolescents with obesity. Randomized controlled trials (RCTs) of exercise ≥4 weeks in children and adolescents with obesity were included if one or more CVD risk factors were included as an outcome. Studies were retrieved by searching 7 electronic databases, cross-referencing, and expert review. Data were pooled using the inverse-variance heterogeneity (IVhet) model and strength of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) instrument. Thirty-nine studies representing 1548 participants (847 exercise, 701 control) met the inclusion criteria. Aerobic exercise improved 10 of 12 (83.3%) outcomes ( P < .05 for all) while combined aerobic and strength training improved 5 of 8 (62.5%) outcomes ( P < .05 for all). The strength of evidence ranged from “very low” to “moderate.” It was concluded that aerobic exercise, as well as combined aerobic and strength training, is associated with improvements in multiple CVD risk factors among children and adolescents with obesity. However, the generally low strength of evidence suggests a need for future well-designed and conducted RCTs on the effects of exercise, especially strength training, in children and adolescents with obesity.
Complex basilar artery fenestration aneurysm successfully treated with single flow diverter using novel “crossing flow diverter technique” – A rare case report and review of literature
Authors: Gaikwad Shailesh B , Puneeth KT , Nadarajah Jeyaseelan , Gupta Madan M
Published: February 2021

Basilar artery fenestration aneurysms are very rare and endovascular management of large and complex aneurysms is extremely challenging. Most of these type of cases are managed with stent assisted coiling, dual flow diverters (FD) and single FD with additional coiling of aneurysm and occlusion of one of the vertebral artery. Here, we report a case of large complex basilar artery fenestration aneurysm successfully treated with single FD using novel technique called “crossing flow diverter technique” without any additional coiling of aneurysm or occlusion of vertebral artery. Using this technique cost of procedure and procedural complexity inherent with other above mentioned techniques can be significantly reduced.
Safety and efficacy of Angio-Seal device for transfemoral neuroendovascular procedures: A systematic review and meta-analysis
Authors: Essibayi Muhammed Amir , Cloft Harry , Savastano Luis E , Brinjikji Waleed
Published: February 2021

Introduction

Angio-Seal is a commonly used device for femoral hemostasis in neuroendovascular procedures. This meta-analysis investigates of the safety and efficacy of Angio-Seal in patients undergoing endovascular neurointerventional procedures.

Methods

A systematic review and meta-analysis on all studies evaluating the Angio-Seal device in neurointerventional procedures from inception through 2020 were performed. We studied rates of groin hematoma, retroperitoneal hematoma, pseudoaneurysm, ipsilateral DVT, and ischemic complications. Meta-analysis was performed using the random-effects model.

Results

13 studies were included in our analysis. 2250 patients with 104 complications were found {4.5% (95% CI, 2.7%–6.3%)}. Of these complications, groin hematoma was the most common with a rate of 2.4% (95% CI, 1.1%–3.6%). Retroperitoneal hematoma {0.3% (95% CI, 0%–0.5%)}, pseudo-aneurysm {0.5% (95% CI, 0.2%–0.8%), and ipsilateral DVT {0.3% (95% CI, 0.1%–0.7%) were also not in negligible rate. The rate of other complications were as follows: vessel occlusion/stenosis; 0.2% (95% CI, 0%–0.4%), vascular surgery; 0.2% (95% CI, 0%–0.5%), and infection; 0.2% (95% CI, 0%–0.5%). One patient died as result of hemorrhagic complications {0.1% (95% CI, 0%–0.3%)}. Use of anticoagulant/antiplatelet therapy was found to be positively correlated with high risk of any groin complication and groin hematoma (p ≤ .05). Female gender was associated with high risk of ipsilateral DVT (p ≤ .05). Interestingly, large sheath size was associated with low risk of groin hematoma (p ≤ .05).

Conclusion

The safety and efficacy rate of Angio-Seal was approximately 95%. The most common complication was groin hematoma. Serious complications including retroperitoneal hematoma and femoral artery occlusion were rare.
On Conversation and Authorship: Legal Frameworks for Collaborative Methodologies
Authors: Rojas Lucero Ibarra
Published: February 2021

Collaborative methodologies are at the forefront of an academic movement seeking to recognize the way social research emerges out of interaction with social actors involved in the processes studied. However, the question of how this recognition can be expressed through authorship is rarely explored. Even though co-authorship is common in different academic fields, including social sciences, the inclusion of actors involved in the social processes studied as co-authors of academic reports is still quite rare. Thus, I here analyze the methodological and epistemological assumptions underlying traditional expressions of authorship embedded in intellectual property models, and how these can be challenged through collaborative methodologies and co-authorship dynamics. I then present a methodological approach that focuses on the co-authored construction of academic texts through conversations, which was developed through four different experiences with scholars and persons involved in different social and political initiatives.

Published: February 2021

Objectives

The significant effects on the treatment of severe carotid stenosis by carotid endarterectomy have been widely recognized. However, it is controversial whether patients with severe contralateral carotid stenosis or occlusion (SCSO) can benefit from carotid endarterectomy surgery. This study aimed to estimate the SCSO effects on early outcomes after carotid endarterectomy with selective shunting.

Methods

Between August 2011 and October 2019, a total of 617 patients who underwent carotid endarterectomy with selective shunting were analyzed. SCSO was defined as >70% luminal narrowing of the contralateral extracranial carotid stenosis or occlusion. Of these patients, 116 were categorized into an SCSO group while the rest were assigned to the non-SCSO group. Primary study outcomes were the occurrence of major adverse events, defined as stroke, all-cause mortality, and myocardial infarction during the perioperative period after carotid endarterectomy. Traditional multivariable logistic regression model and logistic regression model adjusted for propensity scores were used to estimate the SCSO effects on primary outcomes. Interaction and stratified analyses were conducted according to age, sex, comorbidities (hypertension, diabetes), preoperative neurological deficit, preoperative symptoms, and shunt use.

Results

Mean age was 68.5 ± 9.2 years (86.1% men). Overall major adverse events rate within 30 days was 2.5%. Major adverse events rates in SCSO and non-SCSO groups were 9.5% and 1.6%, respectively. This difference was statistically significant ( p < 0.001). In multivariable regression analysis, patients with SCSO had a higher risk of major adverse events (non-SCSO vs. SCSO: aOR 5.05 [95% CI, 1.78–14.55]). In 342 propensity score matched patients, results were consistent (propensity score: aOR, 3.78 [95% CI, 1.13–12.64]).

Conclusions

SCSO is an independent predictor of 30-day major adverse events. Whether these patients with SCSO are suitable for carotid endarterectomy should be carefully considered.

Published: February 2021

Background/Objective

Hydatid disease of the aorta is very rare. Hydatid disease can result in saccular aneurysm of the thoracic and abdominal aorta.

Case report

We report a rare case of saccular aneurysm of the distal descending thoracic aorta. The diameter of the aneurysm was 60 mm. It was managed by Thoracic Endovascular Aneurysm Repair. After 41 months, computed tomography angiography revealed a multi-loculated cystic lesion with 86 × 83×80 mm dimensions in the prevertebral area at the T10-T11 level with bony destruction and erosion of the anterior margin of the vertebral bodies. A computed tomography-guided fine-needle aspiration of the paravertebral cystic lesion was performed. Microscopic study of the fine-needle aspiration specimen demonstrated Echinococcosis granulosus diagnostic of hydatid disease.

Conclusion

It is concluded that the case was a mycotic aneurysm of the thoracic aorta secondary to vertebral hydatid disease.
Barriers and facilitators of implementing an antimicrobial stewardship intervention for urinary tract infection in a long-term care facility
Authors: Chan April J. , O’Donnell Denis , Kaasa Benjamin , Mathers Annalise , Papaioannou Alexandra , Brazil Kevin , Paraschiv Nicoleta , Goldstein Mark , Sadowski Cheryl A. , Dolovich Lisa
Published: February 2021

Background:

Fifty percent of antibiotic courses in long-term care facilities (LTCFs) are unnecessary, leading to increased risk of harm. Most studies to improve antibiotic prescribing in LTCFs showed modest and unsustained results. We aimed to identify facilitators, barriers and strategies in implementing a urinary tract infection (UTI)–focused antimicrobial stewardship (AS) intervention at a LTCF, with the secondary objective of exploring the pharmacist’s potential roles.

Methods:

The study used a qualitative descriptive design. Participants attended either a focus group or one-on-one interview. Data were analyzed inductively using a codebook modified in an iterative analytic process. Barrier and facilitator themes were mapped using the capability, opportunity, motivation and behaviour (COM-B) model. Similarly, themes were identified from the transcripts regarding the pharmacist’s roles.

Results:

Sixteen participants were interviewed. Most barriers and facilitators mapped to the opportunities domain of the COM-B model. The main barrier themes were lack of access, lack of knowledge, ineffective communication, lack of resources and external factors, while the main facilitator themes were education, effective collaboration, good communication, sufficient resources and access. For the pharmacist’s role, the barrier themes were ineffective collaboration and communication.

Conclusion:

This study supports the importance of tailoring interventions to target factors underlying barriers to behaviour change. At this LTCF, an effective antimicrobial stewardship intervention should incorporate strategies to improve access, knowledge, communication and collaboration in its design, having sufficient resources and addressing external factors to optimize its success and long-term sustainability.

Architecture as affective law enforcement: Theorising the Japanese Koban
Authors: Young Alison
Published: February 2021

Criminology has long understood architecture to be both a problem, in that design might increase the pains of an individual’s experience within the criminal justice system, and its solution. Study of the Japanese koban, or police box, reveals the ways in which the architecture and design of a built form communicate the values and objectives of criminal justice. The article draws upon recent criminological thinking about space and about the senses, in which the materiality of public space is understood to have a powerfully affective dimension, and in which meaning arises through the signifying practices of places, events and experiences. In Japan, police boxes have a lengthy history as an architectural manifestation of a mode of policing designed to surveill, reassure, and monitor. Extensive and immersive research conducted in Japan during a 2-year period investigated the ways in which koban both ‘take place’, as built forms within public spaces, and also ‘make sense’, as signifying practice designed to communicate the values and intentions of Japanese community policing and an ‘affective atmosphere’ of law enforcement.
Exploring caring leadership through a feminist ethic of care: The case of a sporty CEO
Authors: Johansson Janet , Edwards Michaela
Published: February 2021

This work critiques the normative construction of ethical leadership and contributes to understanding the ethics of care in leadership from a lifestyle and embodied perspective. Drawing on feminist notions of ethics of care, we question the ethicality of the practices of a sporty and health-oriented leader who claims to transform his attempts at self-care into care for others through role-modelling lifestyle behaviours. We explore inherent moral dilemmas in connecting a seemingly creative self-care project with well-intentioned practices of caring for others. We highlight the need to question persistent masculine rationalisations in ethical leadership, and to engage in and encourage, organisational and relational interactions that take account of specific employee needs. We argue that the leaders’ claiming to care for others by insisting on particular lifestyle behaviours and role-modelling aesthetic bodily ideals introduce new managerial norms in the organisation. The Instrumental intentions come to hamper an ethical care for the well-being of employees, whilst demonstrating the power of the leader to influence employees both inside and outside the organisation.
Can you be a follower even when you do not follow the leader? Yes, you can
Authors: Almeida Teresa , Ramalho Nelson C , Esteves Francisco
Published: February 2021

In the ongoing debate in the area of critical leadership studies, the nature of leader–follower relationships is a thorny issue. The nature of followership has been questioned, especially whether followers can display resistance behaviours while maintaining their follower position. Addressing this issue requires a dialectical approach in which followers and leaders alike are primary elements in leadership co-production. Followers who face destructive leaders are of special interest when leadership is studied as a co-creational process. This context favours the emergence of a full range of behavioural profiles in which passives and colluders will illustrate the destructive leadership co-production process, and those who resist demonstrate that followers may not follow the leader and still keep a followership purpose. A two-step data analysis procedure was conducted based on the behaviour descriptions of 123 followers having a destructive leader. A qualitative analysis (i.e. content analysis) showed a set of behaviours and their antecedents that suggest three main groups of followers: resisters, obedient and mixed behaviour. Treating these data quantitatively (i.e. latent class analysis), six followers’ profiles emerged: active resistance, passive resistance, passive obedience, conflict avoidance, support and mixed. Our findings provide evidence that followers who resist may do it for the sake of the organisation. We discuss our findings in light of followership theory, whereby joining role-based and constructionist approaches allows us to argue that followers may still be followers even when they do not invariably follow their leader.
Individual and collective leadership for deliberate transformations: Insights from Indigenous leadership
Authors: Gram-Hanssen Irmelin
Published: February 2021

Deliberately transforming society toward equitable and sustainable futures requires leadership. But what kind of leadership? While the dominant understanding of leadership often centers on the individual, the concept of collective leadership is receiving increased attention. Yet, the relationship between individual and collective leadership remains elusive and has been given limited attention in the transformation literature. In this study, I explore how leadership is understood and enacted in an Alaska Native community engaged in transforming community systems toward enhanced sustainability. I draw on Indigenous leadership research, organized through four interrelated analytical lenses: the individual leader, leadership through culture, leadership through process, and leadership through integration. I find that leadership in the community can be seen as something simultaneously individual and collective and argue that an Indigenous relational ontology makes it possible to imagine leadership as an “individual-collective simultaneity.” In the discussion, I highlight the connections to emerging theories and approaches within “mainstream” leadership research, pointing to the potential for bridging disciplines and paradigms. For leadership and transformation researchers to engage in this bridging work, we must reflect on and reconsider our assumptions as to what agency for transformation is, with important implications for how we work to support transformations. While “ontological bridge building” creates tensions, it is through holding and working through these creative tensions that we can start to see pathways toward equitable and sustainable futures.
Pra-C exerts analgesic effect through inhibiting microglial activation in anterior cingulate cortex in complete Freund’s adjuvant-induced mouse model

Published: February 2021

Chronic pain is highly prevalent worldwide and severely affects daily lives of patients and family members. Praeruptorin C (Pra-C) is a main active ingredient derived from Peucedanum praeruptorum Dunn, traditionally used as antibechic, anti-bronchitis and anti-hypertension drug. Here, we evaluated the effects of Pra-C in a chronic inflammatory pain mouse model induced by complete Freund’s adjuvant (CFA) injection. Pra-C (3 mg/kg) treatment for just 3 days after CFA challenge relieved CFA-induced mechanical allodynia and hindpaw edema in mice. In the anterior cingulate cortex (ACC), Pra-C treatment inhibited microglia activation and reduced levels of proinflammatory cytokines, TNF-α and IL-1β, and suppressed upregulation of glutamate receptors caused by CFA injection. In addition, Pra-C attenuated neuronal hyperexcitability in ACC of CFA-injected mice. In vitro studies confirmed the analgesic effect of Pra-C was due to its inhibitory ability on microglial activation. In conclusion, Pra-C administration had a certain effect on relieving chronic pain by inhibiting microglial activation, attenuating proinflammatory cytokine releasing and regulating excitatory synaptic proteins in the ACC of the CFA-injected mice.
Enhancement of morphine-induced antinociception after electroconvulsive shock in mice
Authors: Iwata Ken , Takamatsu Yukio , Doi Nagafumi , Ikeda Kazutaka
Published: February 2021

Electroconvulsive therapy (ECT) has been applied for chronic pain for decades. The amounts of opioids to treat pain are sometimes reduced after a series of ECT. The effect of ECT on morphine-induced analgesia and its mechanism underlying the reduction of morphine requirement has yet to be clarified. Therefore, we administered electroconvulsive shocks (ECS) to mice and investigated the antinociceptive effect of morphine in a hot plate test. We examined the expression level of µ-opioid receptor in the thalami of mice 25 h after administration of ECS compared to the thalami of mice without ECS administration using western blotting. ECS disturbed the development of a decrease in the percentage of maximal possible effect (%MPE), which was observed 24 h after a morphine injection, when ECS was applied 25, 23, 21, and 12 h before the second administration of morphine. We also examined the effect of ECS on the dose-response curve of %MPE to morphine-antinociception. Twenty-five hours after ECS, the dose-response curve was shifted to the left, and the EC50 of morphine given to ECS-pretreated mice decreased by 30.1% compared to the mice that were not pretreated with ECS. We also found that the expression level of µ-opioid receptors was significantly increased after ECS administration. These results confirm previous clinical reports showing that ECT decreased the required dose of opioids in neuropathic pain patients and suggest the hypothesis that this effect of ECT works through the thalamus.
The creation of a confidence scale: the confidence in managing challenging situations scale
Authors: Walsh Pauline , Owen Patricia , Mustafa Nageen
Published: February 2021

Background

Self-confidence and self-efficacy are vital psychological constructs that can affect a student’s performance.

Aims

To measure the level of confidence in nursing students in managing challenging situations in clinical practice settings.

Methods

In order to develop the scale three focus groups were conducted: with registered nurses, third year student nurses and service users. Focus group frameworks included: challenging behaviours, managing challenging situations and preparing students to manage challenging situations. Themes in relation to challenging situations that emerged from the focus groups, in conjunction with Nursing and Midwifery Council standards and expert discussions were used to create the confidence scale. The Confidence in Managing Challenging Situations Scale consists of two parts with 21 items in total. Both parts were measured by way of a five-point Likert scale. The scale was utilised to determine the level of confidence of students both pre and post a teaching intervention.

Results

The confidence in managing challenging situations scale had good internal consistency, with a Cronbach’s alpha coefficient reported of 0.86. Exploratory factor analysis was used to support the scale validation process.

Conclusions

The Confidence in Managing Challenging Situations Scale is a successful measure of confidence for nursing students in healthcare settings. It can be applied in alternative healthcare settings for the identification of confidence levels in those student nurses learning in care settings.
Nurses’ caring behaviour and its correlation with moral sensitivity
Authors: Afrasiabifar Ardashir , Mosavi Asadolah , Dehbanizadeh Abolfazl , Khaki Sahar
Published: February 2021

Background

Different and contradictory results have been reported for nurses’ caring behaviour and moral sensitivity.

Aims

The present study aimed to examine the correlation between nurses’ caring behaviour and moral sensitivity.

Methods

The research was a descriptive, correlational study. Data were collected using moral sensitivity (range: 0–100) and caring behaviour (range: 24–144) questionnaires. A total of 250 nurses who worked in the clinical wards of Yasuj teaching hospitals in 2018, were selected by systematic random sampling. The collected data were analysed using SPSS version 19 for descriptive statistics and Pearson correlation tests.

Results

Seventy-four percent of nurses had moderate moral sensitivity (50–74). Nurses’ moral sensitivity and caring behaviour mean scores were reported to be 59.5 ± 11.1 (range: 31–87) (Potential range 0--100) and 110.99 ± 17.99 (range: 69–94) (Potential range 22–144), respectively. The Pearson test showed a positive correlation between nurses’ caring behaviour and moral sensitivity at a 99% level ( p = 0.001).

Conclusions

Nurses’ moral sensitivity and caring behaviour were found to be moderate and good, respectively. Furthermore, there was a positive correlation between moral sensitivity and caring behaviour in nurses, that is, nurses provided better caring behaviour as levels of moral sensitivity increased.
Psychology in an Indeterminate World
Authors: van Dijk Ludger
Published: February 2021

By sharing their world, humans and other animals sustain each other. Their world gets determined over time as generations of animals act in it. Current approaches to psychological science, by contrast, start from the assumption that the world is already determined before an animal’s activity. These approaches seem more concerned with uncertainty about the world than with the practical indeterminacies of the world humans and nonhuman animals experience. As human activity is making life increasingly hard for other animals, this preoccupation becomes difficult to accept. This article introduces an ecological approach to psychology to develop a view that centralizes the indeterminacies of a shared world. Specifically, it develops an open-ended notion of “affordances,” the possibilities for action offered by the environment. Affordances are processes in which (a) the material world invites individual animals to participate, while (b) participation concurrently continues the material world in a particular way. From this point of view, species codetermine the world together. Several empirical and methodological implications of this view on affordances are explored. The article ends with an explanation of how an ecological perspective brings responsibility for the shared world to the heart of psychological science.
The Empirical Status of Mindfulness-Based Interventions: A Systematic Review of 44 Meta-Analyses of Randomized Controlled Trials
Authors: Goldberg Simon B. , Riordan Kevin M. , Sun Shufang , Davidson Richard J.
Published: February 2021

In response to questions regarding the scientific basis for mindfulness-based interventions (MBIs), we evaluated their empirical status by systematically reviewing meta-analyses of randomized controlled trials (RCTs). We searched six databases for effect sizes based on four or more trials that did not combine passive and active controls. Heterogeneity, moderators, tests of publication bias, risk of bias, and adverse effects were also extracted. Representative effect sizes based on the largest number of studies were identified across a wide range of populations, problems, interventions, comparisons, and outcomes (PICOS). A total of 160 effect sizes were reported in 44 meta-analyses ( k = 336 RCTs, N = 30,483 participants). MBIs showed superiority to passive controls across most PICOS ( ds = 0.10–0.89). Effects were typically smaller and less often statistically significant compared with active controls. MBIs were similar or superior to specific active controls and evidence-based treatments. Heterogeneity was typically moderate. Few consistent moderators were found. Results were generally robust to publication bias, although other important sources of bias were identified. Reporting of adverse effects was inconsistent. Statistical power may be lacking in meta-analyses, particularly for comparisons with active controls. Because MBIs show promise across some PICOS, future RCTs and meta-analyses should build on identified strengths and limitations of this literature.
Invisible Hands and Fine Calipers: A Call to Use Formal Theory as a Toolkit for Theory Construction
Authors: Robinaugh Donald J. , Haslbeck Jonas M. B. , Ryan Oisín , Fried Eiko I. , Waldorp Lourens J.
Published: February 2021

In recent years, a growing chorus of researchers has argued that psychological theory is in a state of crisis: Theories are rarely developed in a way that indicates an accumulation of knowledge. Paul Meehl raised this very concern more than 40 years ago. Yet in the ensuing decades, little has improved. We aim to chart a better path forward for psychological theory by revisiting Meehl’s criticisms, his proposed solution, and the reasons his solution failed to meaningfully change the status of psychological theory. We argue that Meehl identified serious shortcomings in our evaluation of psychological theories and that his proposed solution would substantially strengthen theory testing. However, we also argue that Meehl failed to provide researchers with the tools necessary to construct the kinds of rigorous theories his approach required. To advance psychological theory, we must equip researchers with tools that allow them to better generate, evaluate, and develop their theories. We argue that formal theories provide this much-needed set of tools, equipping researchers with tools for thinking, evaluating explanation, enhancing measurement, informing theory development, and promoting the collaborative construction of psychological theories.
Higher education, post-conflict democratization and the legacies of authoritarian rule: The Tripoli University Programme for Rebuilding Libya
Authors: Milton Sansom
Published: February 2021

In this paper, the role of higher education in post-uprising Libya is analysed in terms of its relationship with transitional processes of democratization and civic development. It begins by contextualising the Libyan uprising within the optimism of the ‘Arab Spring’ transitions in the Middle East. Following this, the relationship between higher education and politics under the Qadhafi regime and in the immediate aftermath of its overthrow is discussed. A case-study of a programme designed to support Tripoli University in contributing towards democratisation will then be presented. The findings of the case-study will be reflected upon to offer a set of recommendations for international actors engaging in political and civic education in conflict-affected settings, in particular in the Middle East.
Effect of FIFA 11+ intervention on change of direction performance in soccer and futsal players: A systematic review and meta-analysis
Authors: Liu Ruidong , Liu Jianxiu , Ma Xindong , Li Qing , An Ruopeng
Published: February 2021

This study systematically reviewed scientific literature regarding the effects of the FIFA 11+ intervention on the change of direction (COD) performance in soccer and futsal players. We conducted a keyword search on June 30, 2020, in SPORTDiscus, PubMed, Web of Science, Academic Search Complete, Scopus, CINAHL, and Google Scholar. We performed a meta-analysis to estimate the pooled effect size of FIFA 11+ interventions on COD performance. Sixteen RCTs studies met the eligibility criteria and were included in this review. Compared to the control group, the FIFA 11+ intervention yielded a 0.87 standard deviation (95% CI = 0.52, 1.21; I2 = 96.2%) decrease in the time of COD task completion in soccer and futsal players. In addition, there were no differential effects of the FIFA 11+ intervention compared to the control group in COD performance enhancement among age, gender, athletic level, sport, intervention frequency, intervention duration, and measure covariates. In conclusion, the FIFA 11+ intervention is effective in improving the COD performance of soccer and futsal players. Future studies should recruit large representative samples from professional soccer or futsal teams and examine the effectiveness of the FIFA 11+ intervention on the COD performance among population subgroups (e.g., by age and gender). Studies focusing on different COD tests are warranted to deepen the understanding of the FIFA 11+ intervention effects on the COD performance.
From echo chambers to ‘idea chambers’: Concurrent online interactions with similar and dissimilar others
Authors: Martin Justin D , Hassan Fouad , Anghelcev George , Abunabaa Noor , Shaath Sarah
Published: February 2021

Countering conventional theory, this study found that online homophily and heterophily—connectivity with both similar and dissimilar others—are not necessarily countervailing phenomena, among representative surveys of internet users from five Arab countries: Saudi Arabia, Tunisia, Lebanon, Qatar, and UAE ( N = 4,198). Respondents who said the Internet has increased their contact with politically and religiously similar people also tended to say it increased their contact with politically and religiously dissimilar people. A four-item scale measuring online political and religious homophily and heterophily was reliable (a = .754 overall; .79 among Arab nationals), and is referred to in this article as an ‘idea chamber’ index. Confirmatory Factor Analysis and inter-item correlations of scale items are two additional tests that affirm the internal consistency of the measure. Implications for research on digital communication are discussed.
Reconstruction of a fluttering flag from a single image
Authors: Hu Tao , Li Jun , Guo Guihuan
Published: February 2021

Reconstructing a 3 D object from a single image is a challenging task because determining useful geometric structure information from a single image is difficult. In this paper, we propose a novel method to extract the 3 D mesh of a flag from a single image and drive the flag model to flutter with virtual wind. A deep convolutional neural fields model is first used to generate a depth map of a single image. Based on the Alpha Shape, a coarse 2 D mesh of flag is reconstructed by sampling at different depth regions. Then, we optimize the mesh to generate a mesh with depth based on Restricted Frontal-Delaunay. We transform the Delaunay mesh with depth into a simple spring model and use a velocity-based solver to calculate the moving position of the virtual flag model. The experiments demonstrate that the proposed method can construct a realistic fluttering flag video from a single image.
Reshuffle minimisation to improve storage yard operations efficiency
Authors: Bisira Hammed , Salhi Abdellah
Published: February 2021

There are many ways to measure the efficiency of the storage area management in container terminals. These include minimising the need for container reshuffle especially at the yard level. In this paper, we consider the container reshuffle problem for stacking and retrieving containers. The problem was represented as a binary integer programming model and solved exactly. However, the exact method was not able to return results for large instances. We therefore considered a heuristic approach. A number of heuristics were implemented and compared on static and dynamic reshuffle problems including four new heuristics introduced here. Since heuristics are known to be instance dependent, we proposed a compatibility test to evaluate how well they work when combined to solve a reshuffle problem. Computational results of our methods on realistic instances are reported to be competitive and satisfactory.
Postcatastrophic entanglement? Contemporary Czech writers remember the holocaust and post-war ethnic cleansing
Authors: Tippner Anja
Published: February 2021

The last two decades have seen a rising interest in the Holocaust and the expulsion of ethnic Germans after World War II in Czech literature. Novels by Hana Androníková, Radka Denemarková, Magdalena Platzová, Kateřina Tučková, and Jáchym Topol share a quest for a new poetics of remembrance. Informed by contemporary discussions about Czech memory politics, these novels are characterised by spectral visions of Germans and Jews alike, a dichotomy of trauma and nostalgia, and an understanding of Czech history as postcatastrophically entangled and thus calling for multidirectional forms of remembrance. In this respect, literary memorial forms compensate for the absence of other memorial forms addressing these topics through a transnational lens. The interaction of different historical points of view is achieved by a time frame extending from the war to the present day and stressing the intercultural dynamics of Czechs, Jews, and Germans retroactively. In order to illustrate this entanglement, authors make use of popular genres, such as romance, and create texts shaped by genre fluidity, memory theory, documentary practices, and concepts of transnationality.
Moving hearts: How mnemonic labour (trans)forms mnemonic capital
Authors: Reading Anna
Published: February 2021

This study explores how memory forms may be understood through an economic lens tracing how the labour of remembering adds value to and (trans)forms memories. The study focuses on embodied memories and imaginaries of migration and belonging and the ways in which these are (trans)formed through mobile and social media witnessing into a collective living archive and into objectified memory forms that include art works and digital artefacts situated within global mnemonic commodity chains. Empirically, the article draws on an arts-based collaborative research project, ‘Moving Hearts’ carried out with the UK Migration Museum in 2016–2018 that examined embodied, artistic, and institutional memories and imaginaries of migration. Theoretically, the article builds on the growing body of research in memory studies on the economies of memory, bringing together a political economy approach to memory and work within participatory arts to provide insights into how memory forms may be understood through mnemonic labour and mnemonic capital. Specifically, it shows how the mnemonic labour of participants making, carrying and walking with clay hearts transforms memories of migration and belonging into new kinds of mnemonic capital.
Functional deficits as a result of brachial plexus injury in anterior shoulder dislocation

Published: February 2021

The incidence of brachial plexus injuries in anterior shoulder dislocation remains relatively uncommon. A retrospective study was conducted to observe the natural neurological recovery of patients following these injuries over a 2-year period. Muscle power according to the Medical Research Council scale and sensation were measured from presentation to discharge. In 28 patients, the power grade of proximal muscles supplied by nine injured nerves failed to improve over a median follow-up of 5 months. There was no statistically significant improvement in sensation over a median follow-up of 6 months. Poorer recovery in muscle power score was related to advancing age, whereby every decade increased the risk by approximately 30%. Anterior shoulder dislocation with a plexus injury carries a risk of permanent nerve injury. Patients should be referred for specialist nerve assessment leading to rehabilitation and timely early nerve reconstruction, if indicated.

The aim of this study was to explore the effects of ethanol extracts from Portulaca oleracea L. (ePO) on joint inflammation and to explain the underlying mechanisms. A joint inflammation mouse model was constructed by injecting zymosan, and the Von Frey method was employed and the joint thickness measured. The numbers of leukocytes, neutrophils, and monocytes were counted in the joint cavity and the infiltration of inflammatory cells was assessed by joint histopathological analysis. The mRNA levels of inflammatory cytokines were determined by quantitative RT-PCR and their secretion levels were determined by specific ELISAs. Pre-treatment with ePO inhibited articular mechanical hyperalgesia and edema and ameliorated the recruitment of mononuclear neutrophils and leukocytes. In addition, pre-treatment with ePO improved pathological alternations in the joint tissues by reducing the number of inflammatory cells. Pre-treatment with ePO regulated the nuclear factor erythroid 2-related factor 2 (Nrf2)-related proteins and thereby inhibited oxidative stress. In addition, ePO inhibited NLR family pyrin domain containing 3 (NLRP3) inflammasome-related genes (NLRP3, ASC, pro-caspase-1 and pro-IL-1ß), modulated inflammatory cytokines and the activation of NF-κB. ePO attenuated zymosan-induced joint inflammation by regulating oxidative stress, NLRP3 inflammasome, and NF-κB.
Orbital cellulitis
Authors: Iftakhar Rohael
Published: February 2021

Orbital cellulitis is a significant infection that affects the ocular adnexal and associated orbital tissues. It is often a clinical diagnosis and can present as an ophthalmological emergency. The soft tissues posterior to the orbital septum are involved. Thus, the infection is deep and requires aggressive intervention compared with the more superficial infection of pre-septal cellulitis. Failure of prompt diagnosis and early treatment can lead to loss of vision and can be potentially life-threatening. The article discusses the clinical features, risk factors and management of orbital cellulitis. It provides an overview of the important differentials to consider and resultant complications that can occur.

Background:

Parkinson’s disease (PD) patients experience disabling motor dysfunctions as well as non-motor symptoms (NMSs) that can highly impact their perceived quality of life. Besides pharmacological treatment options, active intervention programs have set some attention in managing these symptoms. However, previous studies mainly assessed the effectiveness of active intervention programs on functional mobility and motor symptoms.

Objective:

This study aimed to investigate the effect of Lee Silverman Voice Treatment (LSVT) BIG, an intensified and personalized physiotherapy (INTENSIVE), and a conventional physiotherapy (NORMAL) on NMSs in PD.

Method:

Forty-four patients with mild to moderate PD were randomly assigned to one of the three treatment groups. LSVT BIG and INTENSIVE were delivered one-on-one in 16 1-hour sessions within 4 weeks (4×/week). Patients assigned to NORMAL received 16 individual 1-hour sessions within 8 weeks (2×/week). The primary outcome measure was the difference in change from baseline in the non-motor symptom assessment scale for Parkinson’s disease (NMSS) between treatment groups to follow up at week 8. Patients were blinded for the NMSS being the primary outcome, but not the different treatment groups.

Results:

ANCOVA (Analysis of Covariance) showed reduced NMSS scores for all groups, with INTENSIVE being superior to NORMAL ( p = 0.033). For secondary outcome measures (stride length, gait velocity and chair rising test) LSVT BIG and INTENSIVE were both superior to NORMAL.

Conclusions:

The study provides evidence that all three exercise programs are effective techniques to improve NMSs as well as motor function in PD.

La télésanté connait un essor fulgurant en ce contexte de pandémie. Or, en cette période d’insécurité mondiale, la santé préventive reprend ses droits. En période de déconfinement, la discipline et la cohésion sociale peuvent se relâcher. Cette enquête sociale vise à décrire un programme d'intervention à distance, réalisé en partenariat avec des locataires de logement communautaire, des infirmières et des étudiantes pour soutenir la littératie en santé au temps de la COVID-19. Le Programme de déconfinement en toute sécurité vise à renforcer les mesures préventives et de soutien avec des groupes en contexte de vulnérabilités économiques et sociales à l’aide de la télésanté. Les infirmières ont développé des pratiques cliniques et psychosociales et renforcé la littératie en santé, soutenant les mesures de santé publique post-COVID-19, surveillant l’éclosion de nouveaux foyers et apaisant les souffrances issues du confinement. À l’aide de cibles de performance des systèmes de santé et d’une perspective de justice sociale, nous avons documenté les défis, les leviers et les menaces à l’usage des pratiques à distance en prévention. Vecteur d’une approche intégrée, la télésanté préventive peut cibler simultanément, la lutte contre les maladies non transmissibles et transmissibles et les inégalités. La pandémie de COVID-19 renvoie à un nouvel équilibre des enjeux qui exige un accompagnement et des pratiques de santé communautaire engagées et critiques.

Financial well-being describes when people feel able to meet their financial obligations, feel financially secure and are able to make choices that benefit their quality of life. Financial strain occurs when people are unable to pay their bills, feel stressed about money and experience negative impacts on their quality of life and health. In the face of the global economic repercussions of the COVID-19 pandemic, community-led approaches are required to address the setting-specific needs of residents and reduce the adverse impacts of widespread financial strain. To encourage evidence-informed best practices, a provincial health authority and community-engaged research centre collaborated to conduct a rapid review. We augmented the rapid review with an environmental scan and interviews. Our data focused on Western Canada and was collected prior to the pandemic (May–September 2019). We identified eight categories of community-led strategies to promote financial well-being: systems navigation and access; financial literacy and skills; emergency financial assistance; asset building; events and attractions; employment and educational support; transportation; and housing. We noted significant gaps in the evidence, including methodological limitations of the included studies (e.g. generalisability, small sample size), a lack of reporting on the mechanisms leading to the outcomes and evaluation of long-term impacts, sparse practice-based data on evaluation methods and outcomes, and limited intervention details in the published literature. Critically, few of the included interventions specifically targeted financial strain and/or well-being. We discuss the implications of these gaps in addition to possibilities and priorities for future research and practice. We also consider the results in relation to the COVID-19 pandemic and its economic consequences.
