Authors: Nijenhuis Sebastiaan B. , Koopmann Till , Mulder Jesper , Elferink-Gemser Marije T. , Faber Irene R. 
Published: January 2024

Abstract
Background
Better methods to support talent identification and development processes may contribute to more effective and efficient athlete development programs in racket sports. Both researchers and practitioners recommend multidimensional and longitudinal approaches to better understand the nature of talent (development). However, the added value of these ‘innovative’ approaches has not yet been clarified for racket sports. This systematic review intends to gain further insight into the outcomes of multidimensional and longitudinal approaches for talent identification and development in racket sports and to provide directions for future talent research.

Methods
Electronic searches were conducted in PubMed, Scopus, SPORTDiscus, and Web of Science (January 2000–August 2022). Search terms covered the areas of racket sports and talent in sports. Studies using multidimensional and/or longitudinal talent approaches were included and analyzed regarding the methodology, included performance characteristics (i.e., anthropometrical, physiological, technical, tactical, psychological), and study findings.

Results
A total of thirty-two studies were included using multidimensional (n = 15), unidimensional longitudinal (n = 3) or multidimensional longitudinal designs (n = 14). Most research covered physiological characteristics (n = 28), while fewer articles investigated anthropometrics (n = 21) and technical characteristics (n = 16). Only limited research investigated psychological (n = 4) and tactical characteristics (n = 1). Almost all studies measured physiological characteristics in combination with other characteristics. There was moderate to strong evidence that physiological and technical characteristics have value for athlete development programs in racket sports. Positive but limited evidence was found for psychological and tactical characteristics. Anthropometrical assessments were generally used as controlling variables for maturation. Study designs varied, and many studies used unidimensional statistical models and analyses within multidimensional study designs and datasets.

Conclusions
This review provides an overview of talent research using multidimensional and/or longitudinal approaches within racket sports and gives guidance on what characteristics to include in decision-making and monitoring processes. However, it remains difficult to draw conclusions about the added values of these approaches due to their variety in methodology. Future talent research should include more consistent study designs and conduct multidimensional and longitudinal studies using multivariate statistical approaches that benefit from the data’s multidimensionality.
Realized volatility spillovers between energy and metal markets: a time-varying connectedness approach
Authors: Cunado Juncal , Gabauer David , Gupta Rangan 
Published: January 2024

AbstractThis paper analyzes the degree of dynamic connectedness between energy and metal commodity prices in the pre and post-COVID-19 era, using the time-varying parameter vector autoregressive connectedness approach of Antonakakis et al. (J Risk Financ Manag 13(4):84, 2020). The results suggest that market interconnectedness increased slightly following the outbreak of COVID-19, although this increase was lower and less persistent than that observed after the Global Financial Crisis of 2008. Furthermore, we find that crude oil was the main net transmitter of shocks before COVID-19 while heating oil, gold, and silver were the main net transmitters of shocks during the COVID-19 pandemic. In contrast, natural gas and palladium were the main net receivers of shocks during the entire sample period, making these two commodities attractive hedging and safe haven options for investors during the pandemic. Overall, our results suggest that hedging and diversification opportunities decrease during crises. Furthermore, they indicate that accurate forecasts of the volatility of several commodities, such as natural gas and different metals, can be obtained by exploiting the information content of crude oil. However, they also reveal that crude oil lost its leading position as a net shock transmitter during the COVID-19 pandemic.
Case series of extradigital glomus tumors: imaging findings, differential diagnosis and radiologic–pathologic correlation
Authors: del Carpio Gabriela Serra , Burgos Eva Manuela Pena , Kreilinger José Juan Pozo , Taboada Daniel Bernabeu , Pensado Manuel Peletero , Viñé Mar Tapia 
Published: January 2024

Abstract
Background
Glomus tumors are benign mesenchymal tumors of the neuromyoarterial glomus bodies. They are generally localized at the subungual area of the fingers. Extradigital or non-subungual glomus tumors are less common. Their diagnosis can be challenging because of their lower incidence, nonspecific symptoms, and the fact that they can be missed during the physical examination. The aim of this case series is to provide an overview of non-subungual glomus tumors, including the patients’ epidemiology characteristics, tumor localization and size, their varied imaging manifestations in ultrasound and magnetic resonance imaging, differential diagnosis and histopathological features.

Main body of the abstract
Our report included 64 patients with the diagnosis of non-subungual glomus tumor in the Pathology Department at the La Paz University Hospital in Madrid from January 1966 to September 2022. There were 44 men and 20 women (mean age, 55.8 years; range, 8–85 years). The tumors had a mean size of 1 cm and were located in the lower limbs in most cases (59.3%). In 17 cases (27%) a diagnostic imaging test was performed (US, MRI or both). The radiological appearance of a glomus tumor on ultrasound was in most cases a circumscribed hypoechoic oval nodule located in the subcutaneous layer. Spectral Doppler can demonstrate both venous and arterial intralesional flow and in some cases a “Vascular stalk sign,'' seen in 4/9 cases. MRI assists in providing a more detailed characterization of these lesions, which present as T2-weighted hyperintense nodules with avid enhancement.

Short conclusion
Glomus tumors are considered rare neoplasms, accounting for a small percentage of all tumors. Our report brings together the most up-to-date information available regarding the imaging findings and differential diagnosis of this entity. Although ultrasound images are not specific, they are crucial for early diagnosis, provide precise location information, and serve as a guide for tumor excision. MRI study helps to better characterize these tumors. The diagnosis is mostly clinical, with confirmation in the histopathologic study.

Abstract
Background
One of the most frequent reasons for gynecologic imaging is adnexal masses. The aim of the study is to assess the diagnostic performance of ultrasonography in the identification of ambiguous adnexal masses using the O-RADS US scoring system.

Methods
This study included 108 cases and involved females with indeterminate adnexal masses, with any age group who were sent to the diagnostic ultrasonography department for evaluation of a worrisome adnexal mass lesion. We excluded patients who refused the examination despite informed discussion with the sonographer and patients with a previous history of operated adnexal lesion.

Results
Based on the O-RADS US score, more than half masses (52.8%) were diagnosed as O-RADS 3, which is low-risk malignant, and 47.2% were diagnosed as O-RADS 4, being intermediate-risk malignant. Regarding US O-RADS categorization in relation to the reference results by pathology, 57 lesions were categorized as O-RADS 3 by the US, and 18 of them was diagnosed as malignant according to pathology. Out of 51 lesions categorized as O-RADS 4 by the US, 30 were diagnosed as benign by pathology. At cutoff 4, the O-RADS US score for malignancy gave a sensitivity of 93.13% (95% CI 25.13–80.78), specificity of 66.72% (95% CI 34.49–76.81), PPV of 93.18% (95% CI 26.07–58.16), and NPV of 75.42% (95% CI 52.13–81.17) with an overall accuracy of 92.56% (95% CI 38.10–72.06).

Conclusions
In order to distinguish between benign and malignant neoplastic lesions, the US O-RADS classification system is a crucial non-invasive diagnostic tool for suspected ovarian tumors.

Authors: Abdelwahab Khaled Mohamed , Ibrahim Wesam Ahmed , Saleh Shereen Abou Bakr , Elbarky Anas Abdelfattah Abdelaziz , Mohamed Ghada Abdelrahman 
Published: January 2024

Abstract
Background
Hepatocellular carcinoma (HCC) is one of the most prevalent and fatal malignancies worldwide. Following an increase in reactive oxygen species (ROS), cancer cells enter an oxidative stress state. As a result, these cells experience an increase in antioxidant activity to counteract oxidative stress. The thioredoxin (TRX) system is a ubiquitous mammalian antioxidant system that neutralizes ROS and maintains intracellular reduction oxidation (redox) balance, which is essential for HCC growth. However, the role of TRX protein in HCC remains largely unknown. Hence, we aimed to assess the diagnostic utility of serum TRX in patients with HCC. A total of 50 patients were consecutively recruited in this observational study. They were classified into three groups: an HCC group (25 patients), a cirrhosis group (15 patients with liver cirrhosis on top of chronic HCV infection), and a control group (10 healthy individuals). Serum TRX levels were measured using ELISA.

Results
Higher serum TRX levels were detected in the HCC group than in the cirrhosis and control groups (140.96 ± 12.70 vs 88.33 ± 10.34 vs 73.10 ± 13.22 ng/mL, respectively; P < 0.001). TRX was independently associated with the presence of HCC (P < 0.001). Regarding the detection of HCC, TRX at a cut-off value of 114 ng/mL had superior diagnostic performance to AFP with an AUC of 1.000, sensitivity of 100%, and specificity of 100%, whereas AFP at a cut-off value of 20.5 ng/mL had an AUC of 1.000, sensitivity of 100%, and specificity of 47%.

Conclusion
Thioredoxin has the potential to be an HCC diagnostic marker. The clinical significance of thioredoxin in HCC requires further investigation.
Insulinoma: Metastatic Recurrence 38 Years Following Initial Diagnosis in Pregnancy
Authors: Preston Christopher A , Sachithanandan Nirupa , Sim Ie-Wen , van Heerden Jon , Farrell Stephen 
Published: January 2024

Abstract
A case of recurrent insulinoma spanning 4 decades is described. Following a delayed diagnosis, hyperinsulinemic hypoglycemia was confirmed in a 24-year-old woman during early pregnancy. Initial surgery, culminating in subtotal pancreatectomy, was noncurative. A 1-cm insulinoma was subsequently resected from the head of the pancreas postpartum, with postoperative resolution of hypoglycemia. However, 32 years later, the patient experienced a recurrence of hypoglycemic symptoms. Eventually, a subcentimeter extrapancreatic lesion was identified anterior to the pancreatic head on gallium-68 DOTA-Exendin-4 positron emission tomography/computed tomography. In 2022, a third operation was performed, with excision of a 4 × 3 mm tumor adjacent to the pancreatic head, and histology confirming insulinoma. She was again cured of symptoms.

Published: January 2024

BACKGROUND AND OBJECTIVES:
Subpial corticectomy involving complete lesion resection while preserving pial membranes and avoiding injury to adjacent normal tissues is an essential bimanual task necessary for neurosurgical trainees to master. We sought to develop an ex vivo calf brain corticectomy simulation model with continuous assessment of surgical instrument movement during the simulation. A case series study of skilled participants was performed to assess face and content validity to gain insights into the utility of this training platform, along with determining if skilled and less skilled participants had statistical differences in validity assessment.

METHODS:
An ex vivo calf brain simulation model was developed in which trainees performed a subpial corticectomy of three defined areas. A case series study assessed face and content validity of the model using 7-point Likert scale questionnaires.

RESULTS:
Twelve skilled and 11 less skilled participants were included in this investigation. Overall median scores of 6.0 (range 4.0-6.0) for face validity and 6.0 (range 3.5-7.0) for content validity were determined on the 7-point Likert scale, with no statistical differences between skilled and less skilled groups identified.

CONCLUSION:
A novel ex vivo calf brain simulator was developed to replicate the subpial resection procedure and demonstrated face and content validity.
Building Your Dream Team: How Indie Teams Can Form, and Thrive Together
Authors: Fahme Minhaz-Us-Salakeen , Adiba Afia 
Published: January 2024

The majority of indie game development teams are driven by the desire to produce a blockbuster game. But there are many obstacles on the way to realizing this desire, especially in the beginning. It is possible to create a game alone, but more often than not, something genuinely amazing involves a group of talented people working together toward a similar objective. Finding the correct stakeholders is one of the biggest problems with starting an independent game development team. People with the required technical talents, such as programmers and artists, as well as those with business acumen, like marketing and finance experts, are included in this. Success depends on being able to locate these people and manage them. But after the correct individuals have been identified, it is crucial to develop open lines of communication and a common comprehension of the project's objectives and expectations. Finding the perfect people to join their team is a problem that independent game development teams frequently encounter. Attracting talented individuals to a brand-new, unproven initiative might be difficult. The attention of skilled people interested in working on cutting-edge and intriguing initiatives might be attracted through networking. There are other things to consider as well since forming a team comes with the type of game one is making, finding skilled teammates, team chemistry, conflict resolution, communication, long-term relation maintenance and leadership aspects. In general, creating and leading an independent game team is a difficult process. There is no specific method for doing this, but with a little help from others' expertise, it is possible to assemble a team of creative people who can collaborate to produce a game that is genuinely enjoyable.
The impact of cyberbullying on loneliness and well-being among Malaysian adolescents: The mediation role of psychological distress
Authors: Samsudin Nadia , Chan Nee Nee , Salarzadeh Jenatabadi Hashem 
Published: January 2024

Background: Cyberbullying is a distinct phenomenon characterised by the rapid dissemination of information, the permanence of content, and the availability of victims. Yet, there is a scarcity of studies in this field, and few studies have looked at the elements that contribute to cyberbullying behaviour. The aim of this study is to examine the relationship of cyberbullying with loneliness and well-being through psychological distress among adolescents in Malaysia. Methods: 386 teenagers with ages ranging from 12 to 18 were chosen using multistage cluster random sampling. To analyse the data, structural equation modeling was applied. Results: According to the study, cyberbullying has a positive relationship with psychological discomfort but a negative relationship with loneliness and general well-being. Additionally, psychological distress (depression, anxiety, and stress) mediates the relationship between cyberbullying and feelings of wellbeing and loneliness. Conclusions: The results ought to spark discussion about potential treatments to enhance teenage wellbeing and prevent emotional and mental health issues caused by social isolation.

Published: January 2024

Background: Different approaches and frameworks are available for those evaluating arts-and-health projects. We share our experience in devising, implementing and reflecting on the evaluation strategy of a complex arts-and-health project rooted in a deep participatory phase and culminating in an immersive nationally touring exhibition. Methods: The evaluation focused on different stakeholders (i.e. workshop participants, clinicians involved in the participatory phase, public audiences, the project team itself) using different approaches (i.e. group reflections, email feedback, 1:1 interviews, feedback cards with creative invitations, online journals). Results: Rich and nuanced observations indicate that a mix of methodologies can produce knowledge about team dynamics, participants’ experiences and audiences’ responses. This strategy, designed at the onset of the project and carried out collaboratively by the interdisciplinary core project team, was responsive to the evolution of the project, resulting in a well-defined, transparent but also reactive evaluation plan to maximise the capture of stakeholder feedback. Conclusion: A clear, collaborative evaluation plan should be devised at the onset of arts-and-health participatory projects.

Published: January 2024

Background: Mortality associated with HIV-associated cryptococcal meningitis remains high even in the context of clinical trials (24–45% at 10 weeks); mortality at 12-months is up to 78% in resource limited settings. Co-prevalent tuberculosis (TB) is common and preventable, and likely contributes to poor patient outcomes. Innovative strategies to increase TB preventative therapy (TPT) provision and uptake within this high-risk group are needed. Protocol: The IMPROVE trial is a nested open label, two arm, randomised controlled strategy trial to evaluate the safety (adverse events) and feasibility (adherence and tolerability) of two ultra-short course TPT strategies, in the context of recent diagnosis and treatment for cryptococcal meningitis. We will enrol 205 adults with HIV-associated cryptococcal meningitis from three hospitals in Uganda. Participants will be randomised to either inpatient initiation (early, week 2) or outpatient initiation (standard, week 6) of 1HP (one month of isoniazid and rifapentine). Participant follow-up is to include TB screening, pill counts and tolerability reviews on alternate weeks until week-18. The trial primary endpoint is TB-disease free 1HP treatment completion at 18-weeks, secondary endpoints: 1HP treatment completion, 1HP discontinuation, grade ≥3 adverse events and serious adverse events, drug-induced liver injury, incident active TB, 18-week survival; rifapentine, fluconazole and dolutegravir concentrations will be measured in a drug-drug interaction sub-study of 15 eligible participants. Discussion: The IMPROVE trial will provide preliminary safety and feasibility data to inform 1HP TPT strategies for adults with advanced HIV disease and cryptococcal meningitis. The potential impact of demonstrating that inpatient initiation of 1HP TPT is safe and feasible amongst this high-risk subpopulation with advanced HIV disease, would be to expand the range of clinical encounters in which clinicians can feasibly provide 1HP, and therefore increase the reach of TPT as a preventative intervention.

Głos buntu. O politycznym potencjale opowieści o Jakubie Szeli na przykładzie spektaklu Historia Jakubowa. Opowieść chłopska i babska
Authors: Bednarek Magdalena 
Published: January 2024

Artykuł podejmuje refleksję na temat politycznego potencjału narracji o wiejskim doświadczeniu w kontekście współczesnych ruchów populistycznych na przykładzie widowiska Historia Jakubowa. Opowieść chłopska i babska Małgorzaty Litwinowicz, który miał premierę w 2020, równolegle z trwającymi Czarnymi Protestami. Analiza tego spektaklu pozwala postawić tezę, że dzięki afektywnemu oddziaływaniu opowieść o chłopskim oporze służy we współczesnej kulturze formowaniu nieliberalnej kategorii ludu jako podmiotu działań politycznych w tych projektach, które mają charakter przynajmniej w części audialny. Wybór głosu jako medium dla sztuki próbującej wyrazić ludowy gniew i jego siłę transformacyjną wobec porządku społecznego jest uzasadniony jego większą zdolnością do afektywnego oddziaływania – a przez to do budowania identyfikacji grupy, a następnie wspólnoty społecznej.
Highly sensitive ammonia sensor based on a PMMA/PANI microwire structure

Published: January 2024

In this paper, a highly sensitive ammonia (NH3) sensor based on a polymethyl methacrylate/polyaniline (PMMA/PANI) microwire structure is designed and implemented. First, a micron-sized PMMA microwire was fabricated and connected with two tapered single-mode fibers to form a coupling structure; thus, the Mach–Zehnder (MZ) interference was successfully excited due to the good light conductivity of the PMMA. It was demonstrated that the coupling structure behaved with a high refractive index detection sensitivity of 3044 nm/RIU. To make it sensitive to NH3, the PANI was selected to mix with PMMA and then formed a micron-level PMMA/PANI fiber. The experimental results showed that the PMMA/PANI fiber can selectively sense NH3 with a high sensitivity of 65.3 pm/ppm. This proposed NH3 sensor not only solves the problem of sensitive film shedding, but also possesses the advantages of good integration, high sensitivity, good selectivity, and short response time.
