Perspectives on relative energy deficiency in sport (RED-S): A qualitative case study of athletes, coaches and medical professionals from a super league netball club
Authors: O’Donnell Justine , White Chris , Dobbin Nick 
Published: May 2023

BackgroundResearch into relative energy deficiency in sport (RED-S) has increased substantially over recent years given the impact on athletes’ health and performance. Most studies have considered sports that place emphasis on the aesthetics, endurance, or weight-restriction. Fewer studies exist in team sports. Netball is a team sport yet to be explored despite players potentially being at risk of RED-S given the high training volumes, sporting culture, internal and external pressures, and small network of coaches and medical professionals. A qualitative case study was used to explore the perspective of athletes, coaches, and medical professionals on RED-S.MethodsSemi-structured interviews were conducted with 13 players, 4 coaches and 4 medical professionals affiliated to a Super League club. Interviews were recorded and transcribedverbatim. The data was analysed using thematic analysis.ResultsFive main themes were identified in this study. Awareness of RED-S amongst athletes and coaches was generally inadequate whereas medical professionals had some awareness of RED-S. Some athletes used contraception to reduce discomfort/pain during menstruation whilst others expressed concerns around long-term contraceptive use and previous menstrual cycle disturbance. Sporting demands, individual and contextual factors, and a preoccupation with body image were associated with nutritional restriction, whilst appearance was a source of internal and external pressure. External pressures also extended to coaches, assessments/feedback, social media, and commentary. Strategies suggested to reduce the risk of RED-S included “hard hitting cases”, multidisciplinary team involvement, and support from the governing body.ConclusionThe findings of this study provide insight into factors potentially associated with the risk of RED-S from an athletes, coaches, and medical professional perspective. This insight can be used to increase overall awareness of RED-S in key stakeholders as well as improve the recognition for the pressures netball athletes face that might alter the level of risk.

Objectives
Recording and reproducing mandibular movements have been of key importance in the practice of dentistry for over a century. Recently, it has become possible to use digital technologies for these tasks. This study presents a preliminary method to try to identify the mandibular instantaneous centres of rotation based solely on intraoral scanners.

Methods
The dentitions of four participants were scanned, multiple inter-occlusal registrations and buccal scans were performed in closed and opened positions. Blender software was used to align the meshes during the post-scan digital workflow. Bite alignment accuracy was assessed and then improved with a strict exclusion protocol. An automated algorithm was used to find rotations between closed stage and open stage meshes.

Results
Our exclusion protocol reduced the bite alignment error significantly (p = 0.001) and the root-mean-square error value of the meshes decreased from 0.09 mm (SD = 0.15) to 0.03 mm (SD = 0.017). However, the remaining translational error caused an unexpectedly large shift in the axis of rotation (mean = 1.35 mm, SD = 0.77) with a 41.83: 1 ratio. As found in other studies, our results showed even a small amount of error during registration can shift the axis of rotation a large amount. This phenomenon will compromise the results of common pantographic methods which assume a rotation axis of the condyle. It also adds valuable information to the concept of instantaneous centers of rotation by revealing their true characteristics.

Published: May 2023

Background
Gut-brain cross-talk may play an important role in modulating neurodevelopment. Few studies have examined the association between antimicrobials that influence infant gut microbiota assemblage and attention deficit hyperactivity disorder (ADHD).

Objective
To examine the association between maternal prenatal antimicrobial use and ADHD in offspring at 10 years of age.

Methods
Data are from the Wayne County Health, Environment, Allergy and Asthma Longitudinal Study, a racially and socioeconomically diverse birth cohort in metropolitan Detroit, Michigan. Maternal antimicrobial use was extracted from the medical record. ADHD diagnoses were based on parental report at the 10-year study visit. Poisson regression models with robust error variance were used to calculate risk ratios (RR). Cumulative frequency of exposure to antibiotics, and effect modification were also evaluated.

Results
Among the 555 children included in the analysis, 108 were diagnosed with ADHD. During pregnancy, 54.1% of mothers used antibiotics while 18.7% used antifungals. Overall, there was no evidence of an association between prenatal antibiotic exposure and ADHD (RR [95% CI] = 0.98 [0.75, 1.29]), but there was an increased risk of ADHD among those with mothers using 3+ courses of antibiotics (RR [95%CI] = 1.58 [1.10, 2.29]). Prenatal exposure to antifungals was associated with a 1.6 times higher risk of ADHD (RR [95% CI] = 1.60 [1.19, 2.15]). In examining effect modification by child sex for antifungal use, there was no evidence of an association among females (RR [95% CI] = 0.97 [0.42, 2.23]), but among males, prenatal antifungal use was associated with 1.82 times higher risk of ADHD (RR [95% CI] = 1.82 [1.29, 2.56]).

Conclusions
Maternal prenatal antifungal use and frequent prenatal antibiotic use are associated with an increased risk of ADHD in offspring at age 10. These findings highlight the importance of the prenatal environment and the need for careful use of antimicrobials.
Transcatheter aortic valve implantation vs. surgical aortic valve replacement for aortic stenosis in Taiwan: A population-based cohort study
Authors: Chung Ching-Hu , Wang Yu-Jen , Jiao Xiayu , Lee Chia-Ying 
Published: May 2023

Objective
Aortic stenosis (AS) is a heart valve disease characterized by left ventricular outflow fixed obstruction. It can be managed by surgical aortic valve replacement (SAVR) or transcatheter aortic valve implantation (TAVI). However, real-world evidence for TAVI or SAVR outcomes is lacking in Taiwan. This study aimed to compare the clinical outcomes of TAVI and SAVR for treating of AS in Taiwan.

Materials and methods
The National Health Insurance Research Database is a nationally representative cohort that contains detailed registry and claims data from all 23 million residents of Taiwan. This retrospective cohort study used this database to compare patients who underwent SAVR (bioprosthetic valves) or TAVI from 2017 to 2019. Survival outcomes and length of hospital stay (LOS) and intensive care unit (ICU) stay between TAVI and SAVR in the matched cohort. A Cox proportional hazards model was performed to identify the effect of treatment type on survival rates while controlling variables including age, gender, and comorbidities.

Results
We identified 475 and 1605 patients who underwent TAVI and SAVR with a bioprosthetic valve, respectively. Patients who underwent TAVI were older (82.19 vs. 68.75 y/o) and more likely to be female (55.79% vs. 42.31%) compared with patients who underwent SAVR. Propensity score matching (PSM) on age, gender, and Elixhauser Comorbidity Index (ECI) score revealed that 375 patients who underwent TAVI were matched with patients who underwent SAVR. A significant difference was found in survival rates between TAVI and SAVR. The 1-year mortality rate was 11.44% with TAVI and 17.55% with SAVR. Both the mean total LOS (19.86 vs. 28.24 days) and mean ICU stay (6.47 vs. 11.12 days) for patients who underwent TAVI were shorter than those who underwent SAVR.

Conclusion
Patients who had undergone TAVI had better survival outcomes and shorter LOS compared with patients who had undergone SAVR in Taiwan.

Authors: Gaia Deivid Valério 
Published: May 2023

A imagem da mulher romana que chegou até nós e que se impôs quase como a única possibilidade de analisá-la no mundo antigo é a da domiseda: a dona de casa (boa esposa, mãe e fiandeira). Além do estudo dessa forma tradicional, que marcou as pesquisas em História Econômica sobre a mulher romana, as questões da atualidade e o avanço das pesquisas científicas nos trazem constantemente a renovação das perspectivas, abordagens e dos problemas em torno desse objeto de estudo. Isso nos leva, inevitavelmente, a questionar sobre o papel da mulher no mundo dos negócios e finanças na Roma Antiga. É possível escrever uma História econômica e financeira das mulheres romanas? Quais são os limites dessa empreitada? Partindo dessa preocupação, o objetivo desse artigo é o de apresentar a inserção da mulher no mundo dos negócios e das finanças e apresentar, também, algumas das múltiplas possibilidades de se escrever a história das mulheres a partir do ponto de vista da História Econômica e Social. O recorte temporal se restringe ao final da República e à época imperial. Este artigo se divide, portanto, em três partes: uma introdução sobre a discussão do discurso da elite que inseria a mulher no quadro da domus; alguns pressupostos metodológicos iniciais para estudar inserção das mulheres na vida econômica e financeira; e, por último os estudos de caso, tomando como exemplo três grupos sociais diferentes de mulheres, que aparecem na documentação implicadas em relações creditícias.

Background The ability to predict the progression to severe dengue is crucial in managing patients with dengue fever. Severe dengue is defined by one or more of the following signs: severe plasma leakage, severe bleeding, or severe organ involvement as it can be a life-threatening condition if left untreated.
Objective To identify clinical manifestations and laboratory parameters associated with dengue hemorrhagic fever disease progression in children by systematic review and meta-analysis.
Methods We searched six medical databases for studies published from Jan 1, 2000, to Dec 31, 2020. The meta-analysis used random-effects or fixed-effects models to estimate pooled effect sizes. We assessed heterogeneity using Cochrane Q and I2 statistics, publication bias by Egger’s test and LFK index (Doi plot), and categorized subgroup analysis by country. This study was registered with PROSPERO, CRD42021224439.
Results We included 49 papers in the systematic review, and we encased the final selected 39 papers comprising 23 potential predictors in the meta-analyses. The other 10 papers were not included because the raw data could not be calculated for the effect measure in the meta-analysis. Among 23 factors studied, seven clinical manifestations demonstrated association with disease progression in children, including neurological signs, gastrointestinal bleeding, clinical fluid accumulation, hepatomegaly, vomiting, abdominal pain, and petechiae. Six laboratory parameters were associated during the early days of illness, including elevated hematocrit, aspartate aminotransferase [AST], and alanine aminotransferase [ALT], low platelet count, low albumin levels, and elevated activated partial thromboplastin time. Dengue virus serotype 2 (DENV-2) and secondary infections were also associated with severe disease progression.
Conclusion This review supports the use of the warning signs described in the 2009 WHO guidelines. In addition, monitoring serum albumin, AST/ALT levels, identifying infecting dengue serotypes, and immunological status can improve the prediction of further risk of disease progression.

Published: May 2023

A 22-year-old woman of Malay ethnicity presented with severe blurred vision in the right eye and experienced periocular pain with eye movement. She had a visual field defect over the affected eye, while an examination showed clinically normal optic discs. Relative afferent pupillary defect was also present in the right eye, with reduced optic nerve function. Optic nerve imaging revealed the ‘doughnut sign’ and ‘tram track’ signs, which are characteristics of optic perineuritis. The patient was initiated on a steroid regime that was tapered off over four months. Her visual function recovered gradually during the treatment until reaching a satisfactory final visual outcome. This is a unique case where optic perineuritis occurred in a normal fundus and magnetic resonance imaging (MRI) served as an important diagnostic tool for the condition.
Optic perineuritis (OPN) is an orbital inflammatory disease that involves the meningeal sheath surrounding the optic nerve.[1] It can be idiopathic or secondary to an underlying systemic autoimmune disorder.[1,2] Visual loss in OPN results from inflammation of the tissue surrounding the optic nerve, resulting in mechanical compression of the nerve and subsequent ischaemia.[1]
OPN can be diagnosed using an optic nerve sheath biopsy, while magnetic resonance imaging (MRI) diagnoses OPN through perineural enhancement, making it a useful diagnostic tool.[2] Upon diagnosis, OPN should be treated with corticosteroids for a prolonged period to ensure visual recovery.[3]
We report a unique case of unilateral OPN with severe visual loss in a young Malay woman with a normal fundoscopy who was successfully treated with prolonged corticosteroids.
(e)Health literacy brokering: bridging sociolinguistic gaps at the welfare office?
Authors: Valen-Sendstad Ingvild B. 
Published: May 2023

Abstract
This comparative case study illuminates communicative strategies arising in contact between two migrant clients, ‘Maria’ and ‘Suda’, and their caseworker at the Norwegian welfare office. Suda and Maria mobilize bureaucratic, digital, and linguistic abilities as part of their health literacies to manage in-person contact, institutional websites, letters, and digital bureaucracy. Additionally, they collaborate with their Norwegian spouses to navigate the complex communicative situation at the welfare office and actively bring up this brokering strategy to increase their social and linguistic authority vis-à-vis their caseworkers. Combining Bourdieusian symbolic power with epistemic stance, and drawing on observations and interviews, I investigate how power and responsibility are negotiated between the women and their caseworkers. In their interactions, brokering strategies function as social capital in several ways, enabling the women to access institutional services, and reassuring their caseworkers that the women have sufficient literacy resources to gain access. I discuss the dual nature of brokering strategies as capital, but also as a factor that may reproduce structural vulnerability, and argue for better understanding of brokering as a health literacy strategy.

Abstract
This paper aims to provide a comparison between properties of CuSn10 bronze alloy produced by two methods: FDM (fused deposition modelling) and casting. Wear behavior, mechanical performance and microstructure of CuSn10 alloy produced by FDM and casting methods were determined and compared. 3D printed parts were sintered at 875 °C for 5 h and casting was done at 1200 °C. The amount of porosity was determined by the metallographic cross-sectional examination. Vicker’s hardness, wear and tensile properties of samples were determined. As a result, the porosity value of the CuSn10 alloy produced by the FDM technique was determined as 5.07 ± 0.53%. Tensile strength values were 233.75 ± 18.48 MPa and 349.04 ± 5.10 MPa for CuSn10 alloys produced by FDM and casting methods respectively. While adhesive wear occurs in both production methods, it was observed that the FDM method reduced the wear resistance.
Research and implementation of non-linear management and monitoring system for classified information network
Authors: He Jun 
Published: May 2023

Abstract
In order to better realize the secret-related information monitoring system, an algorithm based on a nonlinear network is proposed and is combined with the traditional algorithm. This article mainly analyzes the theory of nonlinear networks, designs and trains new network parameters according to their own needs, and combines the nonlinear network as a feature extractor with the existing intrusion detection and wandering detection algorithms, which greatly improves the recognition ability of traditional algorithms. The main feature of a nonlinear network is that it can extract the positional features of objects from the network while also extracting object features, that is, positioning and classification are realized in the same network. As a feature extractor, this network can not only have a higher recognition rate than background difference, hog, and other algorithms but also have a greater ability to extract position information than other convolutional neural networks. The successful application of nonlinear production network systems in TV stations at all levels has greatly improved the editing and production capability and efficiency of TV programs. How to ensure the safe, reliable, stable, orderly, and efficient operation of nonlinear production network systems requires vendors and TVS Taiwan technical staff to jointly conduct in-depth research and summarize their findings. In this article, from the perspective of TV users, information components in nonlinear production network systems are analyzed, including class, title management mode, storage space management, material management, security management, and workflow management in nonlinear systems. Make some analysis, discussion, and summaries of network system and operation management problems. The experimental results show that the nonlinear algorithm in this article has a significant advantage over the original tracking algorithm; that is, most tracking algorithms do not have the ability of category recognition during the initial tracking process, which means that these tracking algorithms cannot accurately know what they are tracking. Because the nonlinear network has the ability to output categories, whether it is initial tracking or tracking loss recovery, nonlinearity has fundamentally better advantages than other tracking algorithms. Therefore, it can be predicted that there is a strong recognition ability in the later monitoring and wandering detection. It has been proved that the nonlinear algorithm can be effectively applied to the secret information monitoring system.

Published: May 2023

Abstract
The effect of titanium dioxide (TiO2) on the thermal properties, morphology, intermolecular interactions, and dielectric response of poly(ethylene oxide)/poly(methyl acrylate) (PEO/PMA) polymer electrolytes was studied. These properties were elucidated based on the empirical point of view through systematic sample characterization using differential scanning calorimetry (DSC), polarized optical microscopy (POM), Fourier-transform infrared (FTIR) spectroscopy and impedance spectroscopy (IS). Without TiO2, lithium perchlorate preferably dissolves in the PEO phase rather than in the PMA phase. When TiO2 is added into PEO/PMA/salt systems, TiO2 shows weak interactions either with PEO or PMA phase. The addition of TiO2 changes the morphology of PEO/PMA systems with or without salt from a homogeneous mixture to a heterogeneous mixture displayed by the presence of two T
gs and through the morphological study. The conductivity of both PEO/PMA with and without salt systems remains constant upon the addition of TiO2. Hence, the presented data here have shown that TiO2 provides only a minor effect on the properties of PEO/PMA with and without salt systems. Indirectly, it shows by adding TiO2 under this experimental study may not bring a significant contribution to the improvement of polymer electrolytes.

Published: May 2023

Abstract
Improved Reliability and Low Latency Communication (IRLC) with Augmented Reality (AR) has become an emerging technology in today’s world. To minimize an accessory adaptation for Customer Equipment (CE) in AR, it may be feasible to offload the AR workload onto the onboard devices. Mobile-Edge Computation (MEC) will improve the throughput of a CE. MEC has caused enormous overhead or communication omissions on wireless media, making it difficult to choose the optimal payload proposition. The proposed system explores on-board devices that work together to achieve an AR goal. Code splitting is a Bayesian network used to examine the overall interdependence of efforts. From a longevity and endurance perspective, it is used to reduce the Probability of Supplier Failure (PSF) of an MEC-enabled AR environment. Weighed Particle Swarm Optimization (WPSO) was proposed despite the reality based on the emphasis on balancing the issue. As a result, a heuristic-based WPSO facilitates to improve the performance measures. A hybrid method could significantly increase the assertion of a predicted PSF in various network scenarios compared to the existing communication technologies. A preliminary iterative approach is suitable for AR operations and IRLC scenarios to generalize the attributes.

Published: May 2023

Abstract
Calcium silicate slag (CSS) is a secondary solid waste produced during the extraction of aluminum oxide (Al2O3) from fly ash. Pulverized CSS can replace part of portland cement as a supplementary cementitious material. This study investigates the content of chemically bound water and the hydration degree of a CSS-cement system while varying the CSS content, water–binder ratio, and hydration age. Results show that adding CSS can appropriately reduce the content of chemically bound water and the hydration degree. A cube hydration model suitable for the CSS-cement system was established, which considered the spatial distribution and the evolution of cement and CSS particles in the hydration unit. Based on the cubic hydration model, the growth process of hydration products of CSS and cement particles was analyzed, the expression for the volume of CSS and cement particles at different hydration stages was deduced, and the hydration degree of the CSS-cement system was calculated. The calculated value of the hydration degree was compared with the test value to verify the correctness of the former. Overall, the results provide a practical experimental and theoretical framework to understand the application of the CSS-cement system.
