How political conflicts threaten energy security and economic growth in Asia: A study on the sanctions imposed on Iran
Authors: Wei Wei , Cui Qi , Cui Heng
Published: October 2021

Given their high dependence on energy imports, Asian countries’ energy security is challenged by international political conflicts that interfere with the global energy supply. This study examines the impacts of the sanctions imposed on Iran on the energy security and economic growth of oil-importing Asian countries. A global computable equilibrium model is applied, and three illustrative scenarios are developed to simulate a full embargo on Iran's oil exports, the utilization of spare oil production capacity of other Persian Gulf countries, and a reduction of their oil exports. The impacts of a full embargo are not disastrous if oil exports from other Persian Gulf petrostates are secured. The utilization of spare oil production capacity could largely buffer the impacts on Asian countries’ oil prices than oil supply. Under a pessimistic scenario, the oil supply of Asian countries would be disastrously disturbed. Moreover, political conflicts would force Asian countries to struggle for oil import sources, straining their relations and causing intense international competition.
Reddit use in the LIS community
Authors: Ming Yue , Matteson Miriam L. , Sun Jingchen
Published: October 2021

This study examined online communications within library and information science (LIS)-related subreddits through the perspectives of social identity theory and social media engagement. A total of 17,049 Reddit posts from three major LIS-related subreddits were harvested through Pushshift by Python. Manual and computational coding methods were used to identify linguistic characteristics of the posts as well as the topicality of the content. Multiple logistic regressions were used to analyze the relationship between psychological and emotional characteristics of the posts and user engagement. Results showed that the majority of posts did not mention a specific type of LIS organization; of the subset that did, public libraries and academic libraries were most frequently referenced. “Library services and usage” was the topic most mentioned within LIS-related subreddits, followed by “librarians and jobs.” Various psychological features of posts including emotional tone score, authentic score, clout score, analytic score, and usage of words related to affective processes, anxiety, social processes, causation, and time were significantly related to user engagement. This study contributes to further understanding of social identity theory and social media engagement within the online communication context of LIS community. Key topics and issues in the LIS field and practical suggestions for strategies to improve social media engagement across LIS community were discussed.

Authors: Sarathchandran Pournamy , Farooq Saba , Dar Javeed , Khan Maria , AlRukn Suhail
Published: October 2021

Background and Purpose

Cerebral venous thrombosis (CVT), also known as cerebral dural venous thrombosis, is not a very common cause of stroke. It has a diverse clinical presentation, with multiple predisposing factors and imaging findings. The incidence of CVT varies in different studies. We hypothesized that the incidence of CVT in Dubai is more than that reported in the West owing to dehydration caused by the high atmospheric temperature.

Methods

We retrospectively reviewed the medical records of all patients aged more than 13 years with appropriate International Classification of Diseases, 9th Revision, codes for the diagnosis of CVT from January 1, 2010 to December 31, 2018 from three major hospitals with an acute stroke service in Dubai, United Arab Emirates.

Results

We identified 138 patients who presented with CVT. The average frequency of CVT was 6.6 per 100,000 population. Fifty percent of the patients presented between May and September, which are considered the hottest months in the UAE. Headache was the most common presentation, followed by seizures. The most important risk factors were the use of oral contraceptive pills, anemia, and polycythemia. Our study showed a higher incidence of anemia, polycythemia, thrombophilia, and abnormal CT brain findings.

Conclusion

In our study, CVT was more common during the months of summer. Anemia and polycythemia were strongly associated with CVT. Public awareness about CVT, its higher incidence during summer months and strategies to avoid dehydration might be considered to reduce the incidence of CVT in summer months. However, larger studies are needed to confirm definite associations.

Published: October 2021

Migration experiences are common for athletes, especially in team sports. Moving from home to a recruiting sport club has become an indispensable career investment. This is also the case in Brazilian futsal, where many developing players move to more promising clubs within the country. This process is often challenging, but little researched. The purpose of this article is to investigate 13 Brazilian men elite futsal players’ intra-national migration experiences during their youth. We aim to: provide insight into what factors allowed players to invest in a futsal career through migration; demonstrate the challenges young players faced during their migration; and describe how they adapted to the futsal context they had moved to. We use a Bourdieusian framework to examine young futsal players’ disposition to intra-national migration and the influence of capitals on their integration in the receiving places. A thematic analysis allowed us to identify that: Players’ disposition to migration was shaped by their families’ habitus and illusio related to futsal; some of the reported issues could have been avoided if clubs had provided more efficient support to young migrant athletes; and families and networks (social capital) were key for players being able to adapt to the new futsal context.
Communicating a History of Sexual Trauma: Partner Responses to Women's Disclosure
Authors: Lukacena Kaylee M. , Mark Kristen P.
Published: October 2021

The study aimed to understand how women who experienced sexual trauma but are now in a healthy relationship perceive their partners’ responses to their disclosure of sexual trauma. Forty-one women completed an in-depth semi-structured phone interview. Responses were analyzed using reflexive thematic analysis, identifying two overarching themes and six subthemes. The results provide a voice to the needs and preferences of women who experienced sexual trauma, but are navigating communication in a healthy relationship. Given that most women disclosed their experiences with partners, this sample provides valuable insight for clinicians, interventionists, and partners of survivors to navigate supportive interactions.
Assessing febrile neutropenia outcomes in patients receiving primary versus secondary prophylactic G-CSF treatment therapy with intermediate neutropenic risk chemotherapy regimens
Authors: Goodin Claire , Ratliff Patrick , Cottingham Lauren , Shely Ryan
Published: October 2021

Background

Prophylaxis with granulocyte colony-stimulating factors (G-CSFs) reduce the severity and duration of chemotherapy-induced neutropenia. Currently, the use of G-CSF prophylactic treatment to prevent neutropenia and its complications varies widely in clinical practice with no standardization for intermediate-risk chemotherapy regimens.

Objective

The purpose of this study was to assess neutropenic outcomes in patients receiving intermediate-risk chemotherapy regimens who receive primary versus secondary prophylactic G-CSFs.

Methods

This is a retrospective, multicenter cohort study of patients who received intermediate risk chemotherapy regimens and at least one dose of G-CSF therapy. 121 patients were included and were divided into primary (n = 76) or secondary prophylaxis (n = 45) groups. The primary outcome for this study was the incidence of neutropenic episodes per course of treatment. The secondary outcomes included the percentage of patients who experienced delays in chemotherapy doses, the number of chemotherapy dose reductions, and the number of subsequent treatment delays.

Results

The incidence of neutropenic episodes over the course of therapy was 0.42 episodes in the primary group compared to 1.52 episodes in the secondary group (p < 0.05). 10.5% of patients in the primary group versus 54.3% of patients in the secondary group experienced chemotherapy dose delays (p < 0.05). There were no statistically significant differences in chemotherapy dose reductions or in the average number of FN risk factors between groups.

Conclusion

This retrospective, cohort study determined that patients receiving intermediate risk chemotherapy regimens should receive primary prophylaxis, regardless of risk factors in order to decrease episodes of neutropenia and chemotherapy dose delays.
Self-Reported Smoking Status 10-Months After a Single Session Intervention Including an Education Conference About Smoking Harms and Announcement of Spirometric Lung-Age
Authors: Derbel Khansa , Maatoug Chiraz , Mchita Amira , Mabrouk Khaoula Hadj , Saad Helmi Ben
Published: October 2021

Background

Studies investigating the effects of announcing spirometric lung-age (SLA) on the smokers’ self-reported smoking status reported conflicting results.

Main objective

To evaluate the effects of a single session intervention including an education conference about smoking harms and announcement of SLA on the participants’ self-reported smoking status.

Methodology

An interventional study was conducted in a cable factory. The intervention included four steps: PowerPoint presentation about raising smoking hazards awareness; general questionnaire; measurement of the anthropometric and spirometric data, and announcement of SLA; and evaluation of the smokers’ self-reported smoking status 10 months later (quitted smoking, decreased consumption; stable consumption, increased consumption).

Results

Thirty-six smokers completed the four steps. Ten months after the intervention, 11.1% of smokers quitted smoking, 52.7% decreased their consumption by 7  ±  4 cigarettes/day, 30.5% kept a stable consumption, and 5.5% increased their consumption by 9  ±  6 cigarettes/day.

Conclusion

Providing an education conference combined with announcing SLA motivated 64% of smokers to quit smoking or to reduce their cigarette consumption.
Media access to court proceedings and documents in Mainland China: The changed and unchanged
Authors: Xu Yanzhu
Published: October 2021

This study examined the status of media access to court proceedings and documents in mainland China. In-depth and qualitative interviews with Chinese journalists revealed that they continue to face significant difficulties in attending court hearings and accessing court documents and information; especially, those involving government officials. Owing to the lack of adequate media access to courts, Chinese journalists are not able to fulfil their role of informing the public about what happens in the judicial system; it also undermines the balance and quality of court reporting. The study also found that China's courts mostly used their own online platforms to release information and broadcast trial proceedings. Consequently, the role of news media and journalists in providing court case information and promoting judicial openness has declined in the age of new media.
A method for predicting subsurface fatigue life of rolling bearings based on macro–micro coupling model
Authors: Li Chang , Chen Zhengwei , Liu Zhaotai , Han Xing , Chen Xinxue
Published: October 2021

The fatigue life of the bearing can be predicted effectively by combining the multifield coupling condition of the working process with the internal microstructure. In this paper, a bearing fluid lubrication model is established based on the computational fluid dynamics method, and the calculation result is coupled to the thermal-solid model by the grid mapping method. Through this method, a bearing thermal-fluid-solid multifield coupling dynamics model is established to obtain the evolution information of bearings. Simultaneously, the micro-characterization experiments of SKF6406 bearing (M50 bearing steel) were carried out by electron backscatter diffraction, scanning electron microscope and nano-indentation. The microstructure model of bearing containing micro-inclusions was established by the Voronoi method. On this basis, the microscopic stress distribution characteristics and the motion law of bearing microstructure under the multifield coupling action are solved. In the end, the fatigue life prediction method of rolling bearing was established.
The de-institutionalisation of power beyond the state
Authors: White Jonathan
Published: October 2021

The making of modern authority centred on efforts to formalise and de-personalise power, and transnational orders such as the European Union have often been viewed as an extension of that project. As this article argues, recent developments tell a different story. More than a decade of crisis politics has seen institutions subordinated to and reshaped by individuals and the networks they form. Locating these tendencies in a wider historical context, the article argues that greater attention to informality in transnational governance needs to be paired with greater recognition of the normative questions it raises. Just as a separation between rulers and the offices of rule was central to the making of modern legal and political structures, the weakening of that separation creates legitimacy problems for contemporary authorities both national and supranational. Rather than acclaimed as flexible problem-solving, the step back from institutions should be viewed as a challenge to accountable rule.
The role of discrimination, assimilation, and gender in the mental health of resettled Somali young adults: A longitudinal, moderated mediation analysis
Authors: Gillespie Sarah , Winer Jeffrey P. , Issa Osob , Ellis B. Heidi
Published: October 2021

Acculturation styles have important associations with future adjustment among immigrants and refugees, yet less is known about the individual and interpersonal factors that influence the strategy an individual adopts. High rates of discrimination may signal the receiving community’s rejection of one’s ethnic group, increasing pressure to assimilate and suppress one’s heritage identity. Within a sample of Somali young adults (18–30, N = 185) resettled in North America, this study tested whether two acculturation styles (assimilation and integration) longitudinally mediate the relation between discrimination and three mental health outcomes (i.e., anxiety, depression, and posttraumatic stress disorder), and whether gender moderated these relations. Discrimination had a direct, positive relation with future mental health symptoms for females, which was not mediated by acculturation strategy. By contrast, the association between discrimination and mental health outcomes for males was fully mediated by increased endorsement of assimilation, but not integration. Experiences of marginalization may erode connections to both the Somali community and to the nation of resettlement, which have been identified as particularly strong protective forces within this community. Interventions targeted at the receiving community to reduce the rates of discrimination toward immigrants and refugees and interventions to strengthen youth’s sense of belonging in both the predominant culture and their culture of origin may improve transdiagnostic mental health outcomes.
Everyday data cultures and USB portable flash drives
Authors: Wilken Rowan , Kennedy Jenny
Published: October 2021

In this article, we present a deeper understanding of everyday data cultures in regards to personal information management practices. We draw on a study involving 14 in-depth interviews with users of portable hard drives and USB portable flash drives in Melbourne, Australia, to examine participants’ reflections on their management of personal information on USB portable devices. In examining participant use of these devices, we consider how they kept (stored) and organized (arranged) information on these devices. We also examined device and data sharing. We conclude by thinking about their increased use within cross-tool information management, including the nexus of portable hard drive/USB use and cloud storage. The argument of this article is that portable hard drives and USBs, due to their miniaturization, ease of portability, affordability and storage capacity, add considerable complexity to established understandings of personal information management practices.
Latinx children’s race- and ethnicity-related identities, beliefs, and preferences
Authors: Williams Amber D. , Bigler Rebecca S. , Ramirez M. Chantal
Published: October 2021

The study of Latinx children’s race- and ethnicity-related identity, beliefs, and preferences has the potential to contribute to theoretical models and policy recommendations concerning intergroup attitudes and relations. We examined a host of such constructs among Latinx children ( N = 61; 72% girls) living in the Southwest US, ranging from 6 to 11 years ( M = 8.45, SD = 1.39). With the goal of assessing individual, group, and age-related variation within—and relations across—measures, we assessed racial/ethnic: (a) identity (i.e., self-categorization, centrality), (b) beliefs (stereotypes, perceived parental social distance), and (c) preferences (friendship choices, social distance). Results indicated that children held more positive attitudes toward Latinx and White children than toward Black children. Children who felt more comfortable around Latinx individuals had more Latinx best friends, and those children who felt that race/ethnicity was an important part of their identity were more likely to report having no Black best friends, suggesting that parents and teachers should discuss race/ethnicity in ways that dispel potential anti-Black prejudice and encourage cross-race/ethnicity friendship.

How do global citizens respond to a global health emergency? The present research examined the association between global citizen identification and prosociality using two cross-national datasets—the World Values Survey (Study 1, N = 93,338 from 60 countries and regions) and data collected in 11 countries at the start of the COVID-19 pandemic (Study 2, N = 5,427). Results showed that individuals who identified more strongly as global citizens reported greater prosociality both generally (Study 1) and more specifically in the COVID-19 global health emergency (Study 2). Notably, global citizen identification was a stronger predictor of prosociality in response to COVID-19 than national identification (Study 2). Moreover, analyses revealed that shared ingroup identity accounted for the positive association between global citizen identification and prosociality (Study 2). Overall, these findings highlight global citizenship as a unique and promising direction in promoting prosociality and solidarity, especially in the fight against COVID-19.
Mechanical behavior of electronic waste concrete columns reinforced with structural fibers and glass fiber reinforced polymer bars: Experimental and analytical investigation
Authors: Zaman Khan Qaiser uz , El Ouni Mohamed Hechmi , Raza Ali , Alomayri Thamer
Published: October 2021

Nowadays, the improper disposal of electronic waste (E-waste) is creating environmental pollution and health problems in developing countries. Moreover, the corrosion of steel bars reduces the serviceability of reinforced concrete columns. Although many researchers studied the behavior of glass fiber reinforced polymer (GFRP) bars in concrete columns, none of the studies investigated the structural performance of structural fiber-reinforced E-waste concrete (SFEC) columns having GFRP reinforcement. The present study aims to examine the structural performance of GFRP reinforced concrete circular columns consisting of polypropylene structural fibers (GSFEC columns) under concentric and eccentric loading. Identical steel bars reinforced concrete columns (SSFEC columns) were also manufactured and tested to failure under the same loading conditions. The experimental program consisted of 18 circular columns (1200 mm × 300 mm) to measure the axial capacity (AC), axial deflections, failure modes, and cracking patterns under different eccentric loadings. The AC of SSFEC columns was larger while the ductility was lower than GSFEC columns. Both GSFEC and SSFEC columns illustrated similar damaging behavior. The eccentric loading led to similar decreases in AC for both GSFEC and SSFEC columns.
A contemporary archaeology of pandemic
Authors: Magnani Matthew , Magnani Natalia , Venovcevs Anatolijs , Farstadvoll Stein
Published: October 2021

Global crises drastically alter human behavior, rapidly impacting patterns of movement and consumption. A rapid-response analysis of material culture brings new perspective to disasters as they unfold. We present a case study of the coronavirus pandemic in Tromsø, Norway, based on fieldwork from March 2020 to April 2021. Using a methodology rooted in social distancing and through systematic, diachronic, and spatial analysis of trash (e.g., discarded gloves, sanitization products), signage, and barriers, we show how material perspectives improve understanding of relationships between public action and government policy (in this case examined in relation to the Norwegian concept of collective labor, dugnad). We demonstrate that the materiality of individual, small-scale innovations and behaviors that typified the pandemic will have the lowest long-term visibility, as they are increasingly replaced or outnumbered by more durable representations generated by centralized state and corporate bodies that suggest close affinity between state directive and local action. We reflect on how the differential durability of material responses to COVID-19 will shape future memories of the crisis.
Perspectives on leadership development in post-Soviet Eurasia
Authors: Gill Roger , Negrov Alexander
Published: October 2021

Young people throughout Eurasia are looking for leadership that is different from what preceding generations experienced in the Soviet era and many people are still accustomed to, namely a less top-down authoritarian style by a solo leader reflecting the outdated ‘Great Man’ model of ‘strong’ leadership and for a more collaborative, participative style with more dispersed leadership. This implies the need for a significant cultural change. Leadership development programmes now need to refocus their philosophy, objectives and methods on ways of developing a culture of participation, trust, a sense of belonging, teamwork and accountability and the required know-how and skills in today’s and future leaders. We present two research projects and a case study that reveal these needs and how a new approach to ethical and effective leadership development that appropriately integrates Western and Eastern values can help to liberate and develop the culture and economies of the Eurasia region and thereby make Eurasia a new global powerhouse.
Critical Narrative Intervention for Health Equity Research and Practice: Editorial Commentary Introducing the Health Promotion Practice Critical Narrative Intervention Special Collection
Authors: Fiddian-Green Alice , Gubrium Aline
Published: October 2021

This special collection of Health Promotion Practice introduces critical narrative intervention (CNI) as a key theoretical framing for an asset-based, narrative, and participatory approach to promoting health and addressing social inequality. Innovative digital and visual methodologies highlighted in this special collection—comics and graphic novels, cellphilms and other participatory film, story booths, digital storytelling, and photovoice—are changing the way critical public health researchers and practitioners forge new knowledge, creating new possibilities for interdisciplinary and activist-based inquiry. Public health research and engagement efforts that critically contend with historically repressive structures and intervene through narrative and participatory processes to enact change with and for disenfranchised communities are long overdue. This special collection showcases six CNI projects that promote equity and justice in the context of LGBTQ, nonbinary, and other gender-diverse young people; people who inject drugs living with hepatitis C virus; young women who trade sex; undocumented and formerly undocumented immigrants; and people living with HIV/AIDS. It is our intent that this collection of exemplars can serve as a guidepost for practitioners and researchers interested in expanding the scope of critical public health praxis. Individually and collectively, the special collection illustrates how CNI can create space for the increased representation of historically silenced populations, redress stigma, and provoke important questions to guide a new era of health equity research.
Legal Issues: Advocacy by and Disabilities of School Nurses
Authors: Zirkel Perry A.
Published: October 2021

This article summarizes the facts and rulings of a recent representative federal appeals court decision concerning the legal claims of two school nurses who lost their positions after advocating on behalf of students with diabetes. Their primary claim was the anti-retaliation protection under the pair of federal laws prohibiting disability discrimination—Section 504 of the Rehabilitation Act and the Americans with Disabilities Act. The second of the two nurses additionally asserted protection under this pair of laws based on her own asserted disabilities. The discussion reveals the sometimes significant difference between legal requirements, as determined by appellate courts, and professional norms, as perceived by practitioners and professors in school nursing.

Post-traumatic stress disorder (PTSD) and substance use disorder (SUD) occur frequently as comorbid diagnoses among adolescents. Historically, these conditions have been treated using a sequential model; however, emerging evidence suggests that an integrated treatment model may be most effective. This article presents two de-identified clinical case studies from an ongoing randomised controlled trial examining the efficacy of an integrated, exposure-based, cognitive-behavioral psychotherapy (CBT) for PTSD and SUD among adolescents (COPE-A), relative to a supportive counselling control condition (person-centred therapy). In both case studies, participants were randomised to receive the COPE-A integrated treatment, which incorporates prolonged exposure (PE) including imaginal and in vivo exposure as a core treatment component alongside CBT for PTSD and SUD. The clinical profile and treatment response of each participant is discussed. Promising results were found in both cases, with substantially reduced traumatic stress symptoms and decreased or stable levels of substance use by the end of treatment. Clinical implications of these early findings are discussed.
Dialectical Behavior Therapy and Cognitive Processing Therapy Delivered Sequentially to a Woman Veteran: A Promising Alternative to Concurrent Dialectical Behavior Therapy–Prolonged Exposure
Authors: Cooper Graham , Zink Alycia , Jordan Shiloh E.
Published: October 2021

Post-traumatic stress disorder (PTSD) and borderline personality disorder (BPD) are complex and chronic conditions that result in impairment across a number of clinically significant domains. Although the two diagnoses reflect distinct clinical syndromes, they often present comorbidly. Furthermore, the comorbidity of the two diagnoses predicts increased symptomatology and may also result in treatment difficulties that would not arise when treating PTSD without a concurrent BPD diagnosis. The challenging nature of comorbid PTSD and BPD diagnoses has led to an increased interest in integrative approaches to treating both diagnoses together. Recent research has suggested that the integration of prolonged exposure (PE; an evidence-based therapy for PTSD) and dialectical behavior therapy (DBT; an evidence-based therapy for BPD) into one treatment approach (CBT–PE) can offer superior outcomes when compared to treating each diagnosis separately. However, at this time, the literature does not document any such examinations with regards to cognitive processing therapy (CPT), another evidence-based therapy for PTSD. This paper reflects a first step towards exploring the integration of CPT and DBT. In this case, a female-identified military Veteran seeking care at a Veterans Affairs healthcare system was treated utilizing integrated, though sequential, CPT and DBT. The clinical results of this case are discussed, as are the implications for other clinicians considering integrating CPT and DBT.

Published: October 2021

To systematically evaluate the clinical effects of platelet-rich plasma in the treatment of lower limb venous ulcers by applying a meta-analysis method. The Pubmed, Cochrance Library, Embase, and OVID EBM Reviews databases were searched for the search terms’platelet-rich plasma” or “Plasma, Platelet-Rich” or “Platelet Rich Plasma” and “lower extremity venous ulcers’ or “Leg Ulcers’ or “Ulcer, Leg”, and a meta-analysis was performed on the published research literature on platelet-rich plasma for lower extremity venous ulcers from January 1900 to April 2021. The outcome indicators were: post-treatment trauma area and healing rate. Revman 5.3 statistical software was applied for meta-analysis. A total of 294 patients with lower extremity venous ulcers were included in six publications, including 148 patients in the experimental group treated with PRP versus 146 patients in the control group treated with conventional therapy. There was a statistically significant difference in the Formula of an ellipse at the end of treatment (CM²) between the experimental group and the control group, with a mean difference of −1.19 (95% CI −1.80 to −0.58, P = .0001; 6 studies, 294 participants moderate quality of evidence). The difference between the healing rate of the experimental group and the control group was statistically significant, with a risk ratio (RR) of 5.73 (95% CI 3.29 – 9.99, P < .00001; 5 studies, 248 participants moderate quality of evidence).There may be publication bias for both Formula of an ellipse at the end of treatment and healing rate. This comprehensive meta-analysis of available evidence suggests that the application of PRP for lower extremity venous ulcers accelerates the wound healing process and improves wound healing rates.

Authors: Ontiveros Narda , Becerril-Gaitan Andrea , Llausas-Villarreal Alejandro , Gonzalez-Urquijo Mauricio , Paredes-Vazquez José Gildardo , Martínez-Resendez Michel Fernando , Fabiani Mario Alejandro
Published: October 2021

Background

The increasing prevalence of venous thromboembolism (VTE) among patients with coronavirus disease 2019 (COVID-19) is a matter of concern as it contributes significantly to patients' morbidity and mortality. Data regarding the optimal anticoagulation regimen for VTE prevention and treatment remain scarce. This study describes the characteristics, treatment, and outcomes of COVID-19 patients with VTE treated in a single academic center in Mexico.

Methods

We conducted a retrospective study of all patients with a positive PCR test for SARS-CoV-2 hospitalized in a single academic center in Monterrey, Mexico, between March 2020 and February 2021, with a radiologically confirmed VTE, including deep venous thrombosis (DVT) and pulmonary embolism (PE). Informed consent was obtained from each patient before reviewing their medical records.

Results

Of the 2000 COVID-19 hospitalized patients, 36 (1.8%) developed VTE and were included in the analysis. The median age was 60 years (range 32-88 years), and up to 78% (n = 28) were males. Most patients (n = 34, 94%) had an underlying comorbidity and 47% (n = 17) had a BMI ≥ 30 kg/m2. In most cases (n=28, 78%), VTE presented as a PE, whereas the remaining 22% (n = 8) had a DVT. The median time between hospital admission and VTE was 8 days (range 0-33 days). Regarding the thromboprophylaxis regimen, 35/36 patients received low molecular weight heparin enoxaparin on admission, most commonly at a dose of 60 mg daily (n = 19, 53%). Other complications presented were superinfection (n = 19, 53%), acute kidney injury (n = 11, 31%), and septic shock (n = 5, 14%). A total of 69% of patients (n = 25) required intensive care unit admission, and patients' overall mortality was 55.6%.

Conclusion

VTE remains a significant cause of increased morbidity and mortality among patients with COVID-19. The strikingly high mortality among patients with VTE highlights the need for further investigation regarding the best preventive, diagnostic, and treatment approaches.
Moral Injury and Light Triad Traits: Anxiety and Depression in Health-Care Personnel During the Coronavirus-2019 Pandemic in Honduras

Published: October 2021

The purpose of the current study was to determine the influence of moral injury and Light Triad (LT) personality traits on anxiety and depression symptoms of health-care personnel during the coronavirus-2019 pandemic. A quantitative, cross-sectional research design was used, the study included a sample of 169 health-care workers from Honduras. Data was gathered through the Moral Injury Symptom Scale for Health Professionals (MISS-HP), Light Triad Scale (LTS), the Generalized Anxiety Disorder-7, and the Patient-Health Questionnaire-9. Results suggest that almost 9 out of 10 respondents experienced at least one potentially morally injurious event, 45.6% were at significant risk of impairment related to moral injury. Working with limited staff and resources, and the implications of it, was the most common potentially morally injurious situation reported by the respondents. Results suggest that MISS-HP Mistrust has significant negative correlations with LT traits. A hierarchical regression model determined that Moral Injury, but not LT traits, significantly affected depression symptoms. On the other hand, anxiety symptoms were significantly predicted by Moral Injury, as did LTS-Humanism. The results were discussed according to their implications for public health policy in Latin America.
Between Subjectivity and Flourishing: Creativity and Game Design as Existential Meaning
Authors: Newsome-Ward Tim , Ng Jenna
Published: October 2021

This article explores how the process of designing videogames may be meaningful–that is, accomplish a larger existential fulfilment or purpose. We use a reflective methodology which triangulates the creative practice of making a videogame with reflections both during and post-practice against philosophical ideas of meaningfulness. Two ideas of meaningfulness emerged. The first is the generative capacity of subjectivity, where meaningfulness is anchored to our investment as creators, as well as in the intertwining of personal histories, experiences and memories between reflection and action. The second is the flourishing of the self in terms of inner growth and self-discovery out of journeying inherent in the game design process. The significance of our enquiry is three-fold: to more holistically understand videogames as being meaningful, to present a reflective methodology to facilitate such understanding, and to more broadly consider videogames as an instantiation of how media is itself existential.

Published: October 2021

Aims

This prospective cohort study reports the 10-year survivorship, patient-reported outcome measures and radiographic outcomes of the first series of the Epoca resurfacing head total shoulder arthroplasty.

Methods

From July 2008 to July 2014, 59 Epoca resurfacing head total shoulder arthroplasties were implanted in 50 patients by a single surgeon. Minimum 4.8 year and maximum 11.3 year follow-up (mean: 7.9 years) was analysed using the latest available Oxford Shoulder Score. Kaplan–Meier survivorship analysis was performed with revision as the end point. Most recent radiographs were reviewed for component radiolucency, osteolysis and proximal humeral migration.

Results

Two shoulders underwent revision (3.4%); one for pain with posterior subluxation following a fall, the other for pain with failure of the glenoid. Kaplan–Meier analysis revealed 10-year survivorship of 98.2% (95% confidence intervals: 88.0%–99.8%). Mean Oxford Shoulder Score improved significantly compared to pre-operative values from 18.2 (5–45) to 46.6 (36–48) ( p < 0.001). Fifty-three shoulders underwent radiographic analysis (89.8%). This revealed humeral radiolucency in two cases (3.8%), glenoid radiolucency in three cases (5.7%) and radiographic rotator cuff failure in eight cases (15.1%).

Conclusion

This prospective cohort study shows excellent 10-year survivorship, medium to long-term clinical and radiological results and for the Synthes Epoca resurfacing head total shoulder arthroplasty.

Irreducible isolated anteromedial radial head dislocation due to ruptured anterior capsule and annular ligament interposition: A case report
Authors: Ikumi Akira , Hara Yuki , Yoshii Yuichi
Published: October 2021

Traumatic radial head dislocation without a bone-associated lesion is uncommon, and irreducible cases are rare. We herein present a case of isolated irreducible anteromedial radial head dislocation due to anterior capsule and annular ligament interposition in a 16-year-old female patient. The patient was injured when she was thrown by an opponent during a judo match, and her right elbow was outstretched, combined with forearm pronation. Open reduction was required because of soft tissue interposition into the radiocapitellar joint. The ruptured anterior capsule and annular ligament were repaired using the overlapping suture technique; hence, the radial head was stabilized. At 3.5 years follow-up, the patient had satisfactory elbow function, and redislocation did not occur; however, mild degenerative changes were observed on radiographs. We discussed the injury mechanism using anatomical features in this case and previous literature.

Biochemical recurrence is an evolving space in prostate cancer, with increasing multidisciplinary involvement. Androgen deprivation therapy has shown proof of its value in complementing salvage radiotherapy in high-risk biochemical relapsing patients; ongoing trials aim to further refine this treatment combination. As systemic treatments, and notably next-generation androgen receptor targeted agents, have moved towards early hormone-sensitive and non-metastatic stages, the prostate specific antigen (PSA)-relapse disease stage will be undoubtedly challenged by future evidence from such ongoing clinical trials. With the use of modern imaging and newer molecular technologies, including integration of tumoral genomic profiling and liquid biopsies in risk stratification, a path towards a precision oncology-focused approach will become a reality to guide in the future decisions for patients with a diagnosis of biochemical recurrence.

Two new xanthone derivatives, spinosusones A (1) and B (2), and a new tryptoquivaline analogue, asperdiazapinone G (3), together with nine known compounds (4-12) were isolated from the EtOAc extract of the marine-derived fungus Aspergillus sp . WHUF03110. The structures of 1-3 were determined by spectroscopic analysis, and comparison with literature data. Most of these isolated compounds were evaluated for their antimicrobial activities against ten Gram-negative and seven Gram-positive bacteria, Mycobacterium smegmatis ATCC 607, Candida albicans ATCC SC5314, and C. albicans YY-1-4. Compound 10 displayed strong antibacterial activity against five Gram-positive bacteria ( Bacillus subtilis 168, Staphylococcus aureus ATCC25923, S. aureus NEWMAN, S. aureus USA300, S. aureus NRS 271) with MIC values ranging from 1.0 to 2.0 μg/mL, and displayed moderate antibacterial activity against four Gram-negative bacteria ( Helicobacter pylori 26695, H. pylori G27, H. pylori 159, H. pylori 129) and M. smegmatis ATCC 607 with a MIC value of 8.0 μg/mL.
The appropriateness of ceftriaxone utilization in government hospitals of Eastern Ethiopia: A retrospective evaluation of clinical practice

Published: October 2021

Introduction:

Drug use evaluation is a method of obtaining information to identify problems related to drug use and if properly developed, a means of correcting the problems. Ceftriaxone is among the most commonly utilized cephalosporins. Owing to a broad spectrum of activity and being used empirically, ceftriaxone has been used inappropriately posing a risk for development of antimicrobial resistance. This study is, therefore, designed to evaluate the appropriateness of ceftriaxone utilization in government hospitals in Harar town.

Methods:

A retrospective cross-sectional study was conducted in four government hospitals of Harar town by reviewing the medical records of 271 patients who received ceftriaxone from 1 January to 31 December 2016. Systematic random sampling was utilized to capture the medical records. Data were entered and analyzed using SPSS version 22.

Results:

From the 271 medical records reviewed majority of patients were from surgical ward ( n = 85, 31.4%) followed by gynecology and obstetrics ward ( n = 67, 24.7%). Demographically, the majority of the patients were female ( n = 142, 52.4%). Patients in the age group of 20–29 years were dominant ( n = 98, 36.2%). A total of 71 drugs were co-administered with ceftriaxone, the most common being metronidazole followed by tramadol. Among the co-administered drugs, unfractionated heparin ( n = 6), warfarin ( n = 5), and enoxaparin ( n = 1) were found to have a moderate drug interaction with ceftriaxone. Ceftriaxone was commonly used for post-operative prophylaxis ( n = 80, 27.5%) followed by for the management of pneumonia ( n = 62, 21.3%). The result of ceftriaxone use evaluation showed that majority ( n = 190, 70.1%) were found to be inappropriate. The inappropriate utilization was primarily due to wrong indication (indications for which ceftriaxone was not the primary option) ( n = 114, 60.0%) followed by wrong duration ( n = 54, 28.4%).

Conclusion:

Ceftriaxone was used inappropriately in more than two-thirds of the patients, with wrong indication and wrong duration contributing the majority. Inappropriate use of antibiotics may potentially lead to the emergence and spread of drug-resistant microorganisms and also ultimately exposes the patient to treatment failure, prolonged hospital stay, and higher cost of therapy.

Background:

Coronavirus disease 19 is a pandemic affecting millions worldwide. Since February 2020, new cases are reported in Saudi Arabia, and regulations have been imposed to control the spread of the disease and raise awareness. This study aimed to assess the knowledge and attitudes of the Kingdom’s residents toward coronavirus disease 19 during the early stages of the pandemic.

Method:

A cross-sectional study of 2071 participants who were recruited from various cities in Saudi Arabia. An online questionnaire was shared through social media, which contained questions about demographic data, general knowledge of coronavirus disease 19, and participants’ attitudes.

Results:

The mean age of the study population was 34 ± 12.4 years. Most of the participants agreed that coronavirus disease 19 is a pandemic and is more serious than seasonal influenza. More than 90% believed that handwashing and social distancing are effective in preventing disease transmission. No significant results were observed when comparing the knowledge of high-risk participants and the normal population. More than half of the cohort were strictly compliant with curfew regulations, handwashing, and face mask. Around 80% of the population is following coronavirus disease 19 news and information through official authorities’ press releases.

Conclusion:

The Kingdom of Saudi Arabia residents showed decent knowledge of coronavirus disease 19. Nevertheless, some information needs emphasizing and proper education. Frequent communication between healthcare authorities and the public is highly recommended.
