Published: June 2021

Abstract
Purpose
To quantify the influence of the femoral tunnel exit (FTE) on the graft bending angle (GBA) and GBA-excursion throughout a full range of motion (ROM) in single-bundle anterior cruciate ligament (ACL) reconstruction.

Methods
Three-dimensional (3D) surface models of five healthy knees were generated from a weight-bearing CT obtained throughout a full ROM (0, 30, 60, 90, 120°) and femoral and tibial ACL insertions were computed. The FTE was simulated for 16 predefined positions, referenced to the Blumensaat's line, for each patient throughout a full ROM (0, 30, 60, 90, 120°) resulting in a total of 400 simulations. 3D GBA was calculated between the 3D directional vector of the ACL and the femoral tunnel, while the intra-articular ACL insertions remained unchanged. For each simulation the 3D GBA, GBA-excursion, tunnel length and posterior tunnel blow-out were analysed.

Results
Overall, mean GBA decreased with increasing knee flexion for each FTE (p < 0.001). A more distal location of the FTE along the Blumensaat's line resulted in an increase of GBA and GBA-excursion of 8.5 ± 0.6° and 17.6 ± 1.1° /cm respectively (p < 0.001), while a more anterior location resulted in a change of GBA and GBA-excursion of -2.3 ± 0.6° /cm (+ 0.6 ± 0.4°/ cm from 0–60° flexion) and 9.8 ± 1.1 /cm respectively (p < 0.001).
Mean tunnel length was 38.5 ± 5.2 mm (range 29.6–50.5). Posterior tunnel blow-out did not occur for any FTE.

Conclusion
Aiming for a more proximal and posterior FTE, with respect to Blumensaat’s line, reliably reduces GBA and GBA-excursion, while preserving adequate tunnel length. This might aid to reduce excessive graft stress at the femoral tunnel aperture, decrease femoral tunnel widening and promote graft-healing.

AbstractPaediatric and adolescent ACL injuries are an emerging health burden, increasing at a higher rate than in adults. They compromise quality of life, affect knee structure and function, lead to the early development of osteoarthritis and are a serious economic burden due to shortened professional careers and subsequent surgeries. Up to 35% of children and adolescents will experience a second ACL injury and this population particularly at high risk of secondary intraarticular soft tissue degeneration and growth abnormalities. However, there is still a lack of high-quality outcome studies on this specific population and many knowledge gaps persist in the current treatment guidelines. It is currently unknown whether ACL reconstruction in this young population decreases the risk of irreversible secondary intraarticular soft tissue degeneration. Furthermore, it is not known whether return to high or elite level sports after paediatric ACL injury or reconstruction should be recommended. The relatively low number of paediatric ACL injuries seen in each hospital makes it necessary to conduct international multi-centre studies to collect robust data to provide evidence-based guidelines for the treatment of these injuries. The Paediatric Anterior Cruciate Ligament Initiative (PAMI) was thus started by the European Society of Sports Traumatology, Knee Surgery & Arthroscopy and opened for patient inclusion in 2018. This comprehensive overview of the first 2 years of the PAMI registry shows that the project is now well consolidated and accepted by the European orthopaedic community. Future challenges include ensuring additional external funding to ascertain long term sustainability and continuous dissemination of the knowledge acquired in scientific journals.

AbstractIn the context of the current teacher education program in Thailand, Technology Pedagogical and Content Knowledge (TPACK) framework is formally recognized as essential qualities of knowledge for a highly qualified preservice teacher in today’s education. TPACK has been attracted to educational researchers for preparing preservice science teachers nationwide. In this study, TPACK was employed for restructuring a preservice science teacher education course with mobile game technology, which was offered in two consecutive semesters with a total enrollment of 115 student teachers in the first cohort and 94 student teachers in the second cohort. A pedagogic module of Mobile Game-based Inquiry Learning in Science (MGILS) has been designed and created in two settings, a usual separated and integrated case-based TPACK support module, and then implemented with the first and second cohort respectively in general science teacher education program at a Rajabhat University of Thailand. They were measured TPACK in terms of four constructs, namely, (a) technological knowledge (TK), (b) technological content knowledge (TCK), (c) technological pedagogical knowledge (TPK), and (d) technological pedagogical content knowledge (TPCK). Considering both qualitative and quantitative data analysis from two cohorts, the results showed preservice science teachers’ incremental TPACK improvement from the implementation of the usual separated and integrated case-based TPACK support module of MGILS. Based on the results of MGILS intervention, it seems to indicate the alleged superiority of the integrated case-based TPACK support over the usual separated TPACK support. The deficits in the use of MGILS module are identified, and possible improvements to enhance TPACK in the mobile game are proposed.
Analysis of determinants of work performance for seafarers based on fuzzy Electre model

Published: June 2021

AbstractNowadays, most shipping companies are aware of the importance of analysing seafarers’ work performance. Thus, improving seafarers’ work performance or finding out the ways by which seafarers’ work performance can be enhanced is becoming one of the decisive factors for the success of any shipping company. Any organization aims to have employees who can accomplish corporate goals and objectives using available resources efficiently and effectively. Manpower performance can be enhanced by putting more emphasis on factors that can stimulate employees’ motivational level, creativity and job satisfaction. In this study, we use literature review and experts’ opinions to identify determinants of workplace performance for seafarers working with Marine Services Company Limited (MSCL), a shipping company owned by the government of Tanzania. The data is collected from a random sample of 30 seafarers working for the MSCL and a Fuzzy Electre Model (FEM) is developed and applied to determine the significance of the factors and sub-factors for the work performance of seafarers. The fuzzy terms are adopted in order to integrate the uncertainty of subjective judgment when evaluating alternatives. The computational results validate the effectiveness of the developed evaluation model. This study is resourceful for the top management of MSCL, as it points out those factors that can directly affect the performance of her seafarers. Seafarers are important assets of any shipping company and thus, this study helps shipping enterprises devise efficient human resource strategies to get maximum benefit from this kind of assets. More importantly, enhanced seafarers’ work performance leads to improved company’s productivity and higher service quality and therefore make the shipping company competitive in the trading markets.

This short review briefly describes the current MRI and PET/CT techniques developed for non-invasive neuroimaging and the future direction of optical imaging techniques to achieve higher resolution and specificity using the second near-infrared (NIR-II) region of wavelength with organic molecules.
Late presentation of unilateral lung agenesis in adulthood
Authors: Parry Arshed Hussain , Raheem Mujahed Abdulsattar Ibrahim , Ismail Hussam Hassan , Sharaf Osama 
Published: June 2021

Abstract
Background
Pulmonary agenesis is a rare congenital anomaly with a reported prevalence of about 1 in 100,000 births. It may be bilateral or unilateral. Among the unilateral form, left lung agenesis is more common (70%); however, it is the right lung agenesis which carries a dismal prognosis due to the frequent association with a gamut of other congenital anomalies and greater degree of mediastinal shift leading to tracheo-bronchial and vascular distortion. The patients of unilateral pulmonary agenesis usually present in infancy or early childhood. Presentation in late adulthood as seen in our patient is rare. We present a case of left pulmonary agenesis that was diagnosed in 4th decade of life.

Case presentation
A 36-year-old male presented with gradually progressive exertional dyspnea of 1 month duration. Clinical examination revealed tachycardia and tachypnea. Chest radiograph showed opaque left hemithorax with ipsilateral mediastinal shift. Computed tomography clinched the diagnosis by demonstrating absence of left main bronchus, lung and left pulmonary artery with shift of heart, and great mediastinal vessels into left hemithorax. The patient was managed conservatively and discharged with attachment to out-patient department for regular follow-up.

Conclusion
Presentation of unilateral lung agenesis in late adulthood, as seen in the present case is extremely rare. This case report highlights that, a rare condition like unilateral pulmonary agenesis, should be considered in the list of differentials in an adult presenting with opaque hemithorax with ipsilateral mediastinal shift on radiography.
A new model of regular black hole in (2+1) dimensions
Authors: Estrada Milko , Tello-Ortiz Francisco 
Published: June 2021

Abstract
We provide a new regular black hole solution in

dimensions with the presence of matter fields in the energy momentum tensor. The inclusion of our proposed energy density plus a negative cosmological constant allows that the solution can have both flat as de Sitter or Anti-de Sitter core. This latter is a proper characteristic of our solution, because other models of regular black holes have only a single type of core. Since the first law of thermodynamics for regular black holes is modified by the presence of the matter fields, we provide a new version of the first law, where a local definition of the variation of energy is defined, and where the entropy and temperature are consistent with the ones previously known in the literature. At the hypothetical limit when the horizon radius

the usual first law

is recovered. The effectiveness of the formalism used to compute the mass of our regular black holes in

dimensions suggests the potential applicability of this method to calculate the mass of other models of regular black holes in

dimensions.
Letter-Poems to Shauki Masi

Published: June 2021

AbstractAn extension of an ongoing haunted queer diasporic kinship practice, this piece consists of letter-poems written to the author’s ancestor, Shauki Masi, who passed away several years ago. In this way, the author offers queer Muslim meditations on the five pillars of Islam: salat (ritual of daily prayer), zakat (alms), sawm (ramzaan), hajj (pilgrimage), and shahadah (declaration of faith). The five pillars of Islam offer a praxis through which Muslims can (re)balance their relationships, communities, and therefore the world.
Development of Functional Materials via Polymer Encapsulation into Metal–Organic Frameworks
Authors: Hosono Nobuhiko , Uemura Takashi 
Published: June 2021

Abstract
Metal–organic frameworks (MOFs) composed of metal ions and organic ligands have been extensively studied over the last few decades owing to their versatile porous structures with controllable sizes and designable surface functionalities. The encapsulation of polymer chains into MOF pores is a powerful strategy for the preparation of functional materials. The nanochannels of MOFs disrupt the natural coiling of polymer chains and constrain them in extended conformations, facilitating the study of the properties of single polymer chains. The formation of nanocomposites between MOFs and polymers can provide unprecedented material platforms to accomplish several nanoscale functions. Furthermore, the use of regulated nanochannels in MOFs for polymer encapsulation allows the discrimination of the marginal structural differences in individual polymer chains, providing the separation of polymers from complex mixtures.

Authors: Manrique-Hernández Edgar F. , Rojas Díaz Marcela Pilar , Rodriguez-Villamizar Laura Andrea 
Published: June 2021

Background: Childhood cancer is considered one the most important causes of death in children and adolescents, despite having a low incidence in this population. Spatial analysis has been previously used for the study of childhood cancer to study the geographical distribution of leukemias. This study aimed to identify the presence of space-time clusters of childhood of cancer excluding leukemia in Colombia between 2014 and 2017. Methods: All incident cancer cases (excluding leukemia) in children under the age of 15 years that had been confirmed by the National Surveillance System of Childhood Cancer between 2014 and 2017 were included. Kulldorf’s circular scan test was used to identify clusters using the municipality of residence as the spatial unit of analysis and the year of diagnosis as the temporal unit of analysis. A sensitivity analysis was conducted with different upper limit parameters for the at-risk population in the clusters. Results: A total of 2006 cases of non-leukemia childhood cancer were analyzed, distributed in 432 out of 1,122 municipalities with a mean annual incidence rate of 44 cases per million children under the age of 15. Central nervous system (CNS) tumors were the most frequent type. Two space-time clusters were identified in the central and southwest regions of the country. In the analysis for CNS tumors, a spatial cluster was identified in the central region of the country. Conclusions: The distribution of non-leukemia childhood cancer seems to have a clustered distribution in some Colombian regions that may suggest infectious or environmental factors associated with its incidence although heterogeneity in access to diagnosis cannot be discarded.

Published: June 2021

Background: Patients with chronic diseases often experience difficulty adhering to recommended treatments as instructed by their healthcare professionals. Recently, diabetes has been associated with the severity of the novel coronavirus disease (Covid-19), which raises the importance of improving medication adherence for diabetic patients to enhance the right use of antidiabetics amid the Covid-19 pandemic. Methods: This work assesses medication adherence among type 2 diabetes mellitus patients in the United Arab Emirates (UAE) and identifies the set of key demographic and health factors significantly associated with medication adherence. A descriptive cross-sectional study was conducted on an appropriate sample of type 2 diabetic patients in the UAE, with 180 patients of both genders and various social levels. A validated version of the eight-item Morisky Medication Adherence Scale (MMAS) was used for data collection. Results: The average MMAS score was 4.88, with 95% confidence intervals (CI) 4.6 and 5.2. 61.67% (n=111), 28.89% (n=52), and 9.44% (n=17) of patients were categorized into low, medium, and high adherent groups, respectively. These findings indicate that a high level of non-compliance to antidiabetic regimens among the population in the UAE. Conclusions: Patients demonstrated low level of compliance to antidiabetic regimens. Therefore, they must receive up-to-date knowledge about the disease and the treatment and enable easy access to their health care providers to enhance medication adherence.

Published: June 2021

Background: Falls in older people are a major cause of morbidity and mortality. There is some evidence to suggest that home hazard assessment and environmental modification delivered by an occupational therapist may reduce falls. The objective of this study was to evaluate the effectiveness of this intervention, relative to usual care. Methods: A pragmatic, two-arm modified cohort randomised controlled trial in eight NHS trusts in primary and secondary care in England. In total, 1331 community-dwelling adults aged 65 years and over with a history of falls or fear of falling were randomised in a 2:1 allocation to either usual care plus a falls prevention leaflet (n=901) or to receive the home hazard assessment and environmental modification intervention, plus usual care and a falls prevention leaflet (n=430). The primary outcome was the number of falls per participant over the 12 months from randomisation. Secondary outcomes included: proportion of fallers and multiple fallers, time to fall, and fear of falling. Results: All 1331 randomised participants (mean age 80 years, 872 [65.5%] female) were included in the primary analysis. There was a small increase in the rate of falls in the intervention group relative to usual care (adjusted incidence rate ratio 1.17, 95% CI 0.99 to 1.38; p=0.07). A similar proportion of participants in the intervention (57.0%) and usual care group (56.2%) reported at least one fall over 12 months. There were no differences in any of the other secondary outcomes and no serious, related adverse events were reported. Conclusions: Home hazard assessment and environmental modification delivered by an occupational therapist did not reduce falls in community-dwelling older people deemed at higher risk of falling recruited to this trial.
Prevalence and patterns of tobacco and/or nicotine product use in Japan (2017) after the launch of a heated tobacco product (IQOS®): a cross-sectional study
Authors: Afolalu Esther F. , Langer Peter , Fischer Karina , Roulet Steve , Magnani Pierpaolo 
Published: June 2021

Background: Several smoke-free tobacco and/or nicotine-containing products (TNP) have emerged in recent years to support tobacco harm reduction strategies and reduce individual health risks and population harm relative to continued cigarette smoking. This paper describes the nationwide prevalence and patterns of TNP use in Japan following the commercialization of one such smoke-free TNP, the heated tobacco product IQOS® (Philip Morris International). Methods: We analyzed the first annual data (2016–2017) of two repeated cross-sectional surveys conducted in a representative sample of the Japanese general adult population (N = 4,878) and a sample of adult IQOS users (N = 2,000). We assessed the prevalence of current TNP use according to type of product (cigarettes, IQOS, e-cigarettes, and other TNPs) in the general population and patterns of TNP use in the IQOS user sample. Results: The prevalence of current use across all TNP in the general adult population was 18.5% (95% confidence interval 17.2–19.5%), with 17.5% (16.4–18.6%) for cigarette smoking and 1.8% (1.4–2.2%) for IQOS use. With regard to the distribution of patterns of use in the IQOS user survey, the majority (63.4% [61.2–65.6%]) were exclusive users of IQOS, followed by 20.6% (18.7–22.5%) of individuals who reported dual use of IQOS and cigarettes. Conclusions: In Japan, cigarette smoking remains the most prevalent way of consuming TNP; however, IQOS is being adopted by a growing number of adult Japanese smokers. These findings serve as baseline data for monitoring trends over time in the use and adoption of potential smoke-free TNP in Japan.
Cohort study on educational well-being of children of Chinese origin adopted into transracial and international families in the Spanish education system
Authors: Doncel-Abad David , Cabrera-Álvarez Pablo 
Published: June 2021

The following dataset focuses on the educational well-being of adopted girls of Chinese origin in Spanish schools. Due to its characteristics, the presence of this group may generate complex interaction dynamics in school; particularly regarding bullying in school linked to factors such as the acceptance of others. These are dynamics, which may indeed condition the educational experience of this social group. Therefore, the aim of creating this dataset is to measure the educational well-being of children of Chinese origin adopted into transracial families in Spain. Although this research was justified by the lack of studies on this social group, we aimed to go one-step further, we also studied the correlation between this social group’s educational experience, and to what extent they show an interest in Chinese culture. As we have written before, we incorporated the concept of Well-Being and we worked with the following indicators: Satisfaction with Life, Social Life, and Bullying in School, Racial Bullying, Personal Identity and Interest in Chinese Culture. To achieve the objective set forth, we conducted a questionnaire. The final sample consisted of 268 individuals. The creation of this dataset provided us with information that can shed light on the relationship between adoption, race/ethnicity and the educational experience of adopted children of Chinese origin.
