Published: February 2023

Aims Fixation techniques used in the treatment of slipped capital femoral epiphysis (SCFE) that allow continued growth of the femoral neck, rather than inducing epiphyseal fusion in situ, have the advantage of allowing remodelling of the deformity. The aims of this study were threefold: to assess whether the Free-Gliding (FG) SCFE screw prevents further slip; to establish whether, in practice, it enables lengthening and gliding; and to determine whether the age of the patient influences the extent of glide. Methods All patients with SCFE who underwent fixation using FG SCFE screws after its introduction at our institution, with minimum three years’ follow-up, were reviewed retrospectively as part of ongoing governance. All pre- and postoperative radiographs were evaluated. The demographics of the patients, the grade of slip, the extent of lengthening of the barrel of the screw and the restoration of Klein’s line were recorded. Subanalysis was performed according to sex and age. Results A total of 19 hips in 13 patients were included. The mean age of the patients at the time of surgery was 11.5 years (9 to 13) and the mean follow-up was 63 months (45 to 83). A total of 13 FG SCFE screws were used for the fixation of mild or moderate SCFE, with six contralateral prophylactic fixations. No hip with SCFE showed a further slip after fixation and there were no complications. Lengthening occurred in 15 hips (79%), with a mean lengthening of the barrel of 6.8 mm (2.5 to 13.6) at final follow-up. Remodelling occurred in all hips with lengthening of the barrel. There was statistically more lengthening in patients who were aged < 12 years, regardless of sex (p = 0.002). Conclusion The FG SCFE screw is effective in preventing further slip in patients with SCFE. Lengthening of the barrel occurred in most hips, and thus allowed remodelling. This was most marked in younger children, regardless of sex. Based on this study, this device should be considered for use in patients with SCFE aged < 12 years instead of standard pinning in situ.

Olecranon fractures
Authors: Duckworth Andrew D. , Carter Thomas H. , Chen Michael J. , Gardner Michael J. , Watts Adam C. 
Published: February 2023

Despite being one of the most common injuries around the elbow, the optimal treatment of olecranon fractures is far from established and stimulates debate among both general orthopaedic trauma surgeons and upper limb specialists. It is almost universally accepted that stable non-displaced fractures can be safely treated nonoperatively with minimal specialist input. Internal fixation is recommended for the vast majority of displaced fractures, with a range of techniques and implants to choose from. However, there is concern regarding the complication rates, largely related to symptomatic metalwork resulting in high rates of implant removal. As the number of elderly patients sustaining these injuries increases, we are becoming more aware of the issues associated with fixation in osteoporotic bone and the often fragile soft-tissue envelope in this group. Given this, there is evidence to support an increasing role for nonoperative management in this high-risk demographic group, even in those presenting with displaced and/or multifragmentary fracture patterns. This review summarizes the available literature to date, focusing predominantly on the management techniques and available implants for stable fractures of the olecranon. It also offers some insights into the potential avenues for future research, in the hope of addressing some of the pertinent questions that remain unanswered.

Is it time to reconsider the indications for surgery in patients with tennis elbow?
Authors: Karjalainen Teemu , Buchbinder Rachelle 
Published: February 2023

Tennis elbow (lateral epicondylitis or lateral elbow tendinopathy) is a self-limiting condition in most patients. Surgery is often offered to patients who fail to improve with conservative treatment. However, there is no evidence to support the superiority of surgery over continued nonoperative care or no treatment. New evidence also suggests that the prognosis of tennis elbow is not influenced by the duration of symptoms, and that there is a 50% probability of recovery every three to four months. This finding challenges the belief that failed nonoperative care is an indication for surgery. In this annotation, we discuss the clinical and research implications of the benign clinical course of tennis elbow. Cite this article: Bone Joint J 2023;105-B(2):109–111.
Thin flexible multi-octave metamaterial absorber for millimeter wavelengths

Published: February 2023

The development of radiation-absorbent materials and devices for millimeter and submillimeter astronomy instruments is a research area of significant interest that has substantial engineering challenges. Alongside a low-profile structure and ultra-wideband performance in a wide range of angles of incidence, advanced absorbers in cosmic microwave background (CMB) instruments are aimed at reducing optical systematics, notably instrument polarization, far beyond previously achievable specifications. This paper presents a metamaterial-inspired flat conformable absorber design operating in a wide frequency range of 80–400 GHz. The structure comprises a combination of subwavelength metal-mesh capacitive and inductive grids and dielectric layers, using the magnetic mirror concept for a large bandwidth. The overall stack thickness is a quarter of the longest operating wavelength and is close to the theoretical limit stipulated by Rozanov’s criterion. The test device is designed to operate at a 22.5° incidence. The iterative numerical-experimental design procedure of the new metamaterial absorber is discussed in detail, as well as the practical challenges of its manufacture. A well-established mesh-filter fabrication process has been successfully employed for prototype fabrication, which ensures cryogenic operation of the hot-pressed quasi-optical devices. The final prototype, extensively tested in quasi-optical testbeds using a Fourier transform spectrometer and a vector network analyzer, demonstrated performance closely matching the finite-element analysis simulations; that is, greater than 99% absorbance for both polarizations, with only a 0.2% difference, across the frequency band of 80-400 GHz. The angular stability for up to ±10∘ has been confirmed by simulations. To the best of our knowledge, this is the first successful implementation of a low-profile, ultra-wideband metamaterial absorber for this frequency range and operating conditions.
Activity impairment, health-related quality of life, productivity, and self-reported resource use and associated costs of uncomplicated urinary tract infection among women in the United States

Published: February 2023

Background
Uncomplicated urinary tract infections (uUTIs) are among the most common infections in the US. Only a few studies, however, describe the impact of uUTIs from the patient perspective.

Methods
A cross-sectional online survey of US women aged ≥18 years was performed assessing uUTI burden regarding activity impairment, health-related quality of life (HRQoL), workplace productivity, healthcare resource use (HRU), and costs. Participants who self-reported a uUTI in the prior 60 days treated with ≥1 oral antibiotic were included. Activity impairment was assessed with the Activity Impairment Assessment scale. HRQoL was assessed using a modified Short Form 36 (SF-36). Direct costs were sum of out-of-pocket expenditures and monetized HRU; indirect costs were calculated using Work Productivity and Activity Impairment (WPAI). Participants were stratified by uUTI recurrence, number of prescribed antibiotics for recent uUTI and therapy appropriateness (1 first-line/1 second-line/multiple antibiotics). Multivariable regression analysis assessed the relationship between stratifications and outcomes while controlling for demographic/clinical characteristics. Propensity score matching was used to compare participants to a matched population from the 2020 National Health and Wellness Survey (NHWS), to control for any impact of COVID-19 on responses.

Results
Among 375 participants, impaired activities included sexual intercourse (66.9%), sleep (60.8%) and exercise (52.3%). HRQoL was worse (p<0.0001) than the NHWS population (46.4 vs. 51.3 [physical component score]; 40.0 vs. 46.9 [mental component score]; 0.63 vs. 0.72 [health utility index]). All included WPAI assessments were worse for uUTI cohort vs. NHWS (p<0.0001). Adjusted direct costs were higher for participants receiving 2 vs. 1 antibiotic ($2090 vs. $776; p<0.0001) and receiving multiple antibiotics vs. 1 first-line ($1642 vs. $875; p = 0.002). Recurrent uUTI was associated with increased activity impairment, worse HRQoL, and costs vs. non-recurrent.

Conclusions
uUTIs were associated with increased activity impairment, worse productivity, and reduced HRQoL. Higher costs were found vs. a matched population.

BackgroundHmong men in Minnesota exhibit a high prevalence of gout and hyperuricemia. Although evidence of vitamin C’s effectiveness as a treatment for gout is mixed, analysis of therapeutic benefit based on an individual’s multiomic signature may identify predictive markers of treatment success.ObjectivesThe primary objective of theHmongMicrobiomeANdGout,Obesity, VitaminC(HMANGO-C) study was to assess the effectiveness of vitamin C on serum urate in Hmong adults with and without gout/hyperuricemia. The secondary objectives were to assess if 1) vitamin C impacts the taxonomic and functional patterns of microbiota; 2) taxonomic and functional patterns of microbiota impact vitamin C’s urate-lowering effects; 3) genetic variations impact vitamin C’s urate-lowering effects; 4) differential microbial biomarkers exist for patients with or without gout; and 5) there is an association between obesity, gut microbiota and gout/hyperuricemia.MethodsThis prospective open-labelled clinical trial was guided by community-based participatory research principles and conducted under research safety restrictions for SARS-CoV-2. We aimed to enroll a convenient sample of 180 Hmong adults (120 with gout/hyperuricemia and 60 without gout/hyperuricemia) who provided medical, demographic, dietary and anthropometric information. Participants took vitamin C 500mg twice daily for 8 weeks and provided pre-and post- samples of blood and urine for urate measurements as well as stool samples for gut microbiome. Salivary DNA was also collected for genetic markers relevant to uric acid disposition.Expected resultsWe expected to quantify the impact of vitamin C on serum urate in Hmong adults with and without gout/hyperuricemia. The outcome will enhance our understanding of how gut microbiome and genomic variants impact the urate-lowering of vitamin C and associations between obesity, gut microbiota and gout/hyperuricemia. Ultimately, findings may improve our understanding of the causes and potential interventions that could be used to address health disparities in the prevalence and management of gout in this underserved population.Trial registrationClinicalTrials.govNCT04938024(first posted: 06/24/2021).
Possibilities of Autologous Fecal Microbiota Transplantation in patients with obesity and diabetes mellitus
Authors: Guseinova R. M. , Shestakova E. A. 
Published: February 2023

Obesity and type 2 diabetes mellitus (T2DM) are major problems for public health all over the world. According to retrospective research, the prevalence of obesity has doubled in more than 70 countries since 1980, as well as the prevalence of obesity complications (atherosclerotic cardiovascular diseases, nonalcoholic fatty liver disease and their complications. There are many drug therapies for T2DM, but it is difficult to achieve a stable, clinically relevant effect on a long-term basis. The fact that a patient has both conditions makes it difficult to optimize carbohydrate metabolism and to achieve normal body weight. Many antidiabetic drugs cause weight again, which, in turn, contributes to the growth of insulin resistance (IR) and requires further intensification of therapy.In the last few years, there is a growing evidence of the relationship between the gut microbiota (GM), obesity and T2DM. There has been a steady growth of interest in such medical technology as fecal microbiota transplantation (FMT) in the world. Since there is data on the association of the gut microbiota (GM) with the development of IR and T2DM, the possibility of FMT can potentially be one of the new methods of treatment. This review presents the current state of the problem and discusses the possibility of modifying GM as a therapeutic strategy in obesity and T2DM with an accent on autologous fecal microbiota transplantation.
Plato’s Use of Mogis (Scarcely, with Toil) and the Accessibility of the Divine
Authors: Brown Ryan M. 
Published: February 2023

Abstract
At key moments in the Phaedrus and the Republic, Socrates qualifies our capacity to “see” the highest realities (the “place of being,” the “Good beyond being”) with the adverb “mogis” (mogis kathorosa, Phdr. 248a; mogis horisthai, Rep. 517b). Mogis can be used to indicate either the toilsome difficulty of some undertaking or the subject’s proximity to failing to accomplish the undertaking. Socrates uses mogis to qualify the nature of the human soul’s capacity to make the intellectual ascent and see the divine, but it is not prima facie clear whether the qualification is meant to express (1) the difficulty we have in undertaking the intellectual ascent (a comment on the effort required) or (2) the fact that the human soul’s capacity to make the intellectual ascent will, on account of its limitations, only “just barely” be achieved, if at all. After discussing the uses of mogis in classical literature and surveying Plato’s uses of mogis across the corpus, I interpret Plato’s use of mogis at Phaedrus 248a, arguing that mogis kathorosa should be translated as “only gets a good look at the things that are with much toil” rather than the more common “scarcely able to gaze upon the things that are.” I then turn to the parallel passage at Republic 517b and argue against a prominent account, put forward by John Sallis, among others, of Plato’s understanding of divine inaccessibility. Whereas Sallis et al. argue that Plato’s use of mogis indicates that which is to be seen at the acme of the ascent is only “barely glimpsed” on account of the fact that it “withdraws” from our view, I argue instead that Plato’s use of mogis indicates that though we can “get a good look” at the highest realities, that good look is qualified by their inexhaustible excess. The human capacity to see the highest realities is qualified because there is “always more to see,” not because that which is there to be seen “withdraws” from view, and still less because there is some intrinsic limitation to human intellectual vision that prevents us from apprehending the highest realities. Accordingly, the divine is accessible but never exhaustible.
Inter-league Competition and the Optimal Broadcasting Revenue-Sharing Rule
Authors: Rocaboy Yvon 
Published: February 2023

Abstract
We propose a model where two sports leagues compete for sporting talent, and at the same time consider the competitive balance in their domestic championships. The allocation of broadcasting revenues by the league-governing body acts as an incentive for teams to invest in talent. We derive a strategic league authority’s optimal sharing rule of broadcasting revenues across teams in the league. While a weighted form of performance-based sharing is the best way of attracting talent, cross-subsidization from high- to low-payroll teams is required to improve competitive balance. The optimal sharing rule is then a combination of these two “sub-rules”. We show that the distribution of broadcasting revenues in two first divisions in European men’s football, the English Premier League (EPL) and the French Ligue 1 (L1), corresponds to the optimal sharing rule we discuss. We propose a new method to assess empirically the cross-subsidization impact of the sharing formula. As the impact of cross-subsidization is greater in the EPL than L1, we conclude that ensuring domestic competitive balance seems to be a more important target for the EPL than for L1.
Vaccine-related conspiracy and counter-conspiracy narratives. Silencing effects
Authors: Corbu Nicoleta , Buturoiu Raluca , Frunzaru Valeriu , Guiu Gabriela 
Published: February 2023

Abstract
Recent research explores the high proliferation of conspiracy theories about COVID-19 vaccination, and their potential effects within digital media environments. By means of a 2 × 2 experimental design (N = 945) conducted in Romania, we explore whether exposure to media messages promoting conspiracy theories about vaccination versus media messages debunking such conspiracy narratives could influence people’s intention to either support or argue against vaccination in front of their friends and family (interpersonal influence). We also analyze the moderation effects of education and critical thinking. Main results show that both conspiracy and counter-conspiracy media content about vaccination negatively affect people’s willingness to discuss the topic with others, which offers support for a silencing effect. Education and critical thinking moderate the main effects, but only to some extent and in certain experimental conditions.
Approaching motion in a second language: how bilinguals restructure motion event expressions inside and outside the classroom
Authors: Treffers-Daller Jeanine , Aveledo Fraibet 
Published: February 2023

AbstractIn this introduction, we focus on three approaches to motion event construal, and explain how the papers in this special issue contribute to ongoing discussions in different fields of research. First of all, in second language (L2) acquisition, researchers ask to what extent L2 learners can separate the different conceptual systems that underpin motion in both languages, and whether there is crosslinguistic influence from the first language (L1) on the L2 or vice versa in the expression of motion. In particular research on gestures in SLA can throw new light on this issue. Second, linguists and psychologists are interested in finding out whether crosslinguistic differences might have an influence on non-linguistic cognition in the motion domain. This might be revealed in experimental tasks where speakers are asked to judge the similarity of film clips in contexts where no overt language is used. The third relevant question is to what extent this conceptually complex domain can be taught. This pespective on motion event construal has received very little attention from researchers interested in Instructed Second Language Acquisition. In the current SI, insights from cognitive grammar are used to explore the teaching of motion event construals to L2 learners, but we hope that the current SI will inspire researchers working in different frameworks to explore the teachability of motion in the classroom.

Authors: Yang Dongfang , Lv Heng 
Published: February 2023

AbstractA finite group 𝐺 is normally monomial if all its irreducible characters are induced from linear characters of normal subgroups of 𝐺. In this paper, we study the largest irreducible character degree and the maximal abelian normal subgroup of normally monomial 𝑝-groups of maximal class in terms of 𝑝. In particular, we determine all possible irreducible character degree sets of normally monomial 5-groups of maximal class.

The impact of gestural representation of metaphor schema on metaphor comprehension
Authors: Khatin-Zadeh Omid , Hu Jiehui , Marmolejo-Ramos Fernando , Farsani Danyal 
Published: February 2023

Abstract
This study aimed to investigate how priming a metaphor by the gestural representation of its schema affects the understanding of that metaphor. In each of the two tests, different groups of participants were invited to judge the sensibility of the same 20 metaphors preceded by congruent versus incongruent gesture primes as compared to no prime. In the congruent gesture-prime conditions, each metaphor was preceded by a gesture that represented the schema of the subsequent metaphor whereas this gesture was not compatible with the schema of the subsequent metaphor in the incongruent gesture-prime conditions. Results showed that a higher proportion of sentences were judged to be sensible in the congruent gesture-prime conditions compared to no-prime and incongruent gesture-prime conditions. Also, response times of sensibility judgements were shorter in congruent gesture-prime conditions compared to no-prime and incongruent gesture-prime conditions. These results suggest that metaphor schema affects metaphor comprehension through the activation of metaphorically-relevant information and suppressing irrelevant information.
On-site contactless visualization of the laminar-turbulent flow transition dynamics on wind turbines
Authors: Gleichauf Daniel , Oehme Felix , Parrey Ann-Marie , Sorg Michael , Balaresque Nicholas , Fischer Andreas 
Published: February 2023

Abstract
Thermographic flow visualization is already an established imaging method to localize the laminar-turbulent flow transition on the rotor blades of operating wind turbines, while a steady flow state is assumed. To understand the potential of thermographic flow visualization for the investigation of unsteady flow phenomena, its capability to detect the change of the flow transition position due to a wind gust is studied. Previously laminar flow regions become turbulent with the gust, which means a sudden increase of heat transfer between surface and fluid and, thus, a decrease of surface temperature. The latter is detected by evaluating the difference of thermographic images before and during the wind gust. The achievable sensitivity and the temporal resolution are limited by the thermodynamic properties of the rotor blade and the fluid flow, as well as by the natural rotor blade heating with the sun’s radiation. As a result of theory and experiments on real wind turbines, the feasibility to detect flow state changes in the order of seconds is proven. This opens upthe analysis of unsteady flow phenomena on wind turbines by means of thermographic flow visualization.
