Published: October 2024

Background and aims
The effects of metabolic obesity (MO) phenotypes status and their dynamic changes on urologic cancer (UC) is ignored. We aimed to investigate the association between metabolic syndrome (MetS) and MO status at baseline, their dynamic changes and UC risk.

Methods
This paper studied 97,897 subjects who were free of cancers at baseline (2006−2007). Individuals were classified into four MO phenotypes by MetS and obesity at baseline. Transitions in MetS and MO status from 2006–2007 to 2008–2009 were considered. The hazard ratios (HRs) and 95% confidence intervals (CIs) for UC were assessed by multifactorial Cox proportional risk regression models. The main limitations of this study are as follows: the ratio of men to women in the cohort is unbalanced; the impacts of MetS and MO on each cancer type (kidney cancer, prostate cancer, bladder cancer) have not been analyzed separately; the transition intervals of MetS and MO phenotypes are relatively short.

Results
From baseline (2006–2007) survey to December 31, 2020, during a median follow-up of 14.02 years, 554 cases of UC were diagnosed. Participants with MetS [HRs (95% CI) = 1.26 (1.06–1.49)] and metabolically unhealthy obesity (MUO) [HRs (95% CI) = 1.49 (1.17–1.89)] had significantly higher risk of UC than those with non-MetS and metabolically healthy normal weight (MHN). Transitions in MetS and MO phenotypes over time were studied. Compared with non-MetS to non-MetS, the risks for UC in MetS to MetS [HRs (95% CI) = 1.45 (1.11–1.88)] was increased. Compared with MHN to MHN, both MUO to metabolically healthy obesity (MHO) [HRs (95% CI) = 2.65 (1.43–4.92)] and MUO to MUO [HRs (95% CI) = 1.60 (1.06–2.42)] had significantly higher UC risk.

Conclusions
MetS and MUO increased the UC risk at baseline. Transitions of MetS to MetS, MUO to MUO and even MUO to MHO over time significantly increased the risk of UC development.

Objective: to conduct a comparative analysis of factors associated with the development of medication overuse headache (MOH), considering demographic characteristics of patients and comorbid pathology.Material and methods. A prospective study was conducted at "Europe–Asia" International Medical Center. The main group comprised patients with primary headache (HA) aged 18 years and older with MOH, and the control group comprised patients with primary HA without MOH of comparable gender and age. A semi-structured interview was conducted with the patients and additional examinations were performed, including MRI of the brain if indicated. The study included 171 patients with MOH (mean age 43.3 years, 82% women) and 173 patients without MOH (mean age 41.4 years, 75% women).Results. Chronic migraine occurred more frequently in the MOH group (53 and 16%, respectively; p<0.001; OR 5.9; 95% CI 3.6–9.8). One third of patients in both groups suffered from chronic tension-type headache (CTH). Episodic migraine and episodic CTH occurred more frequently in patients without MOH (p<0.001). Patients in the MOH group were more frequently divorced (11.7 and 2.9%, respectively; p=0.002; OR 4.5; 95% CI 1.6–12.2). The majority of patients (76%) in both groups were employed, had a higher education (65% with MOH and 74% without MOH) and were married (63% with MOH and 72% without MOH).The analysis of more than 20 comorbid diseases revealed that three factors were most frequently associated with the development of MOH: chronic insomnia (60.2 and 47.4% respectively; p=0.02; OR 1.7; 95% CI 1.1–2.6), restless legs syndrome (37.4 and 22% respectively; p=0.002; OR 2.1; 95% CI 1.3–3.4) and subjective cognitive impairment (76 and 53.2% respectively; p<0.001; OR 2.8; 95% CI 1.8–4.8).Conclusion. Sleep disturbance, subjective cognitive impairment and marital status of patients are most frequently associated with MOH, indicating the great importance of these factors in the development of MOH and opening new opportunities for its prevention.

Published: October 2024

Migraine in children can manifest itself in non-pain clinical phenotypes, among which several episodic syndromes associated with migraine (ESAM) are identified. A significant association with the later development of migraine was found for infantile colic syndrome, benign torticollis, abdominal migraine (AM), cyclic vomiting syndrome (CVS) and benign paroxysmal vertigo (BPV).Objective: to identify the clinical and epidemiological characteristics of childhood ESAM and its association with migraine.Material and methods. The study was conducted in Tambov Children's Clinical Hospital. A total of 250 children were included in the study: 120 (48%) girls and 130 (52%) boys aged 5 to 18 years (mean age 13±2.9 years, median age 13 [11; 15] years) with headache complaints. The diagnosis of ESAM was made according to the ICHD-3 criteria.Results. ESAM was observed in 95 (38%) patients aged 5–18 years. An analysis of the prevalence of ESAM in the different age groups showed that in children aged 5–10 years CVS (n=12; 4.8%) was more common than AM (n=6; 2.4%) and BPV (n=5; 2%). In the group of 11–14 year-old children, the frequency of AM clearly predominated (n=11; 4.4%), while in the group of 15–18 year-old adolescents, BPV (n=15; 6%) was observed more frequently compared to CVS (n=9; 3.5%) and AM (n=5; 2%).Conclusion. The results of the study indicate a high incidence of ESAM in child and adolescent patients of somatic and neurological hospitals. The data obtained show the importance of timely diagnosis and correct treatment of ESAM.

The state's awareness of increased growth and economic opportunities in the industrial sector encourages the state to take on roles and responsibilities so that the state intervenes in the form of regulations on the imports of non-B3 waste as raw material for the recycling industry. However, as the waste import activities were carried out, many B3 wastes were found to be entering. Researchers see that the problem of importing B3 waste needs to be seen from the point of view of implementing policies that have been formed based on the interests of the state and then finding out to what extent the state plays a role and what the results of this policy is when implemented by the state. Researchers seek to see the implementation of this policy through the role of the state concept and the perspective of Edwards III. Based on the final results, several obstacles were found in the implementation of the non-B3 waste import regulatory policy, therefore policy did not work as expected.Keywords: the role of the state, policy implementation, imported waste.
Bringing team science to the ambulatory diagnostic process: how do patients and clinicians develop shared mental models?

Published: October 2024

Abstract
The ambulatory diagnostic process is potentially complex, resulting in faulty communication, lost information, and a lack of team coordination. Patients and families have a unique position in the ambulatory diagnostic team, holding privileged information about their clinical conditions and serving as the connecting thread across multiple healthcare encounters. While experts advocate for engaging patients as diagnostic team members, operationalizing patient engagement has been challenging. The team science literature links improved team performance with shared mental models, a concept reflecting the team’s commonly held knowledge about the tasks to be done and the expertise of each team member. Despite their proven potential to improve team performance and outcomes in other settings, shared mental models remain underexplored in healthcare. In this manuscript, we review the literature on shared mental models, applying that knowledge to the ambulatory diagnostic process. We consider the role of patients in the diagnostic team and adapt the five-factor model of shared mental models to develop a framework for patient-clinician diagnostic shared mental models. We conclude with research priorities. Development, maintenance, and use of shared mental models of the diagnostic process amongst patients, families, and clinicians may increase patient/family engagement, improve diagnostic team performance, and promote diagnostic safety.
When do Entrepreneur Sellers Have to Earn Their Exit?
Authors: Garofolo Andrew , Cox Kevin , Sproul Curtis 
Published: October 2024

Abstract
Entrepreneurial exits can come with various conditions attached. This study investigates the use of earnouts in small business acquisitions, particularly with entrepreneurial firms where uncertainty and valuation challenges are prevalent. Through a comprehensive analysis of 6,184 firms between 2013 and 2019, we explore the factors influencing the likelihood of earnout inclusion, such as sell price, firm leverage, firm age, employment agreements, and noncompete clauses. Employing a Logit model and a treatment effects model, our research reveals which entrepreneurial firms have to earn their exit versus those that do not have to earn their acquisition price. The findings not only enhance our theoretical understanding of earnouts but also provide practical insights for structuring small business acquisition transactions that align buyer and seller interests, mitigate risks, and facilitate smoother post-acquisition integration.

Abstract

Objective
The objective of the current study was to compare the level of sensitivity of body mass index (BMI) or waist-height ratio (WHtR) in identifying physically determinable adiposity levels that are considered to be landmarks for commencing intervention to prevent more sinister cardio-metabolic risks among schizophrenia patients receiving olanzapine.

Methods
The study was a descriptive crossectional one among patients with schizophrenia recieving olanzapine and healthy volunteers as controls. Key measurement of anthropological parameters were compared between the population.

Results
Our findings revealed significantly higher rates of abnormal body mass index (BMI) (X2=17.06, p=0.000036; OR=4.58, CI=2.16–9.74) and abnormal waist-height ratio (WHtR) (X2=35.57, p=2.46E-9; OR=6.37, CI=3.39–12.00) among the schizophrenia patients compared to the healthy volunteers. Notably, BMI identified 43.3 % of the schizophrenia patients as having concerning weight changes, whereas WHtR identified 64.7 %, indicating that WHtR is a more sensitive measure. This discrepancy means that an additional 21.4 % of schizophrenia patients would benefit from weight management guidance based on WHtR rather than BMI.

Conclusion
Our results underscore the critical importance of WHtR in assessing adiposity among schizophrenia patients treated with olanzapine, highlighting its value as a tool for monitoring and managing cardiometabolic risks in this population.

Abstract

Objectives
Healthcare-associated infections (HAIs) are common complications in healthcare services, often caused by unsystematic antibiotic use. Despite advancements in medical care and technologies, the burden of HAIs continues to increase globally. Thus, this study purposed to evaluate the levels of knowledge, attitudes, and practices toward infection control precautions among nurses in Palestinian hospitals and identify the predictors of practices of infection control precautions.

Methods
A cross‑sectional study was conducted on 285 nurses who work at Palestinian hospitals in the West Bank. A self-reported questionnaire was used to collect data during the period from November 2022 to January 2023.

Results
The results revealed that 95.8 % of the participants endorsed good knowledge levels, 83.5 % reported positive attitude levels, and 91.2 % endorsed good practice levels toward infection control precautions. Also, gender as being female, attending a training program on infection control, and having good knowledge of infection control precautions were the main factors influencing practices of infection control precautions.

Conclusions
It is necessary to maintain nurses’ knowledge, attitudes, and practices toward infection control precautions by continuously conducting training workshops about infection control updating knowledge, and enhancing the work environment by implementing infection control policies and guidelines and providing sufficient resources and equipment to ensure safe practices.

Imaging of microcrack propagation in 3D nanostructures applying laboratory nano-XCT
Authors: Zschech E. , Kutukova K. 
Published: October 2024

Abstract
Laboratory X-ray microscopy and nano X-ray computed tomography (nano-XCT) have the unique capability to combine sub-100nm resolution and high object penetration. Therefore, these are appropriate non-destructive inspection techniques for the detection of flaws with a size of 100 nm and below in opaque objects and bulk materials. Another advantage of X-ray microscopy – as opposed to destructive failure analysis methods – is that kinetic processes such as microcrack evolution can be imaged. The unique combination of micromechanics and high-resolution 3D imaging allows to study degradation and failure mechanisms in opaque 3D nanopatterned structures, and it allows to provide essential information for fracture mechanics in small dimensions. The high-resolution in-situ/operando imaging of microcrack propagation in microelectronic products and in battery electrodes is demonstrated.
Specimen preparation for atom probe tomography
Authors: Felfer P. , Ott B. , Vorlaufer N. 
Published: October 2024

Abstract
In the past 20 years or so, atom probe tomography has gone from a niche technique in physical metallurgy to a well-established method in many parts of materials science and beyond. This is owing to the improvement in both instrumentation and specimen preparation. Given the availability of instruments, successful specimen preparation is often the bottleneck in atom probe projects. In this article, the authors want to give an overview of the types of preparation techniques that are available and which challenges they pose. This includes basic electropolishing, which was dominant until the introduction of focused ion beam-based preparation some 25 years ago. Nowadays, focused ion beam-based preparation methods possibly represent the largest share, as they allow for site-specific specimen preparation, non-conductive specimens and often a higher throughput. They are continuously improved, i. e., through higher current plasma ion columns, cryo preparation for sensitive materials and room temperature liquids and ‘additive’ techniques for nanomaterials. This steadily increases the types of materials that can be analyzed using atom probe tomography.

На решении тестовой задачи для односкоростного процесса переноса частиц с изотропным рассеянием и размножением в стохастической среде проводится сравнительный анализ двух алгоритмов оценки взвешенного среднего потока частиц: по частицам и по столкновениям. Показано, что первый из них предпочтительнее для простой оценки среднего потока, а второй - для оценки параметров возможного суперэкспоненциального роста потока. Рассматриваются две модели случайной среды: хаотическая «мозаика Вороного» и сферически «слоистая мозаика». При одинаковом среднем корреляционном радиусе для слоистой мозаики суперэкспоненциальный рост оказался более сильным.
A comparative analysis of two algorithms for estimation of weighted mean particle flux - «by particles» and «by collisions» - is made on the basis of test problem solving for a single-speed particle propagation process with scattering and multiplication in a random medium. It is shown that the first algorithm is preferable for a simple estimation of the mean flux and the second one, for estimation of the parameters of a possible superexponential flux growth. Two models of the random medium are considered: a chaotic «Voronoi mosaic» and «a spherically layered mosaic». For a fixed mean correlation radius, the superexponential growth has been stronger for the layered mosaic.

Используя теорему о геометрических рядах, мы преобразуем линейное интегральное уравнение Фредгольма второго рода, определенное на большом интервале, в эквивалентную линейную систему интегральных уравнений Фредгольма второго рода. Затем мы уточняем, как исследуемая обобщенная итерационная схема аппроксимирует искомое решение. Не обращая ограниченный линейный оператор, а вместо этого вычисляя усеченную геометрическую сумму связанной с ним последовательности ограниченных линейных операторов, мы замечаем, что наш подход обеспечивает лучшую эффективность с точки зрения времени вычислений и наличия ошибок.
Based on the use of the geometric series theorem, we transform a linear Fredholm integral equation of the second kind defined on a large interval into an equivalent linear system of Fredholm integral equations of the second kind; then, we inflict a refinement in the way the investigated generalised iterative scheme approximates the sought-after solution. By avoiding to inverse a bounded linear operator, and computing a truncated geometric sum of the former's associated sequence of bounded linear operators instead, we notice that our approach furnishes a better performance in terms of computational time and error efficiency.

В статье решается задача об определении температуры на внутренней стенке полого цилиндра. При помощи преобразования Фурье по времени задача сведена к обыкновенному дифференциальному уравнению, с помощью которого был найден Фурье-образ точного решения искомой обратной граничной задачи. Для применения преобразования Фурье по времени искомое решение было умножено на e-t и сведено к двум некорректным задачам. В работе рассмотрен метод проекционной регуляризации, позволяющий получить устойчивое решение задачи, а также получена точная по порядку оценка погрешности приближенного решения.
The article solves the problem of determining the temperature on the inner wall of a hollow cylinder. Using a time Fourier transform, the problem is reduced to an ordinary differential equation, with the help of which the Fourier transform of an exact solution of the inverse boundary value problem is found. A projection regularization method is considered, which makes it possible to obtain a stable solution to the problem and an accurate in order of magnitude estimate of the error of the approximate solution. Since high accuracy requirements are imposed on solutions of such problems in numerical calculations, an algorithm is developed to improve the accuracy and reliability of processing the results of thermal test data. To check the performance of the algorithm, test calculations are carried out.
ИСПОЛЬЗОВАНИЕ СХЕМЫ ЛАКСА-ФРИДРИХСА С МАЛОЙ ДИССИПАЦИЕЙ ДЛЯ МОДЕЛИРОВАНИЯ РЕЛЯТИВИСТСКИХ ТЕЧЕНИЙ ГАЗА

Схема Лакса-Фридрихса традиционно является альтернативой схеме Годунова, так как не требует решения задачи Римана. Использование в случае уравнений специальной релятивистской гидродинамики в схемах Рое, Русанова и в семействе схем Хартена-Лакса-Ван Леера естественного ограничения скорости распространения волн скоростью света приводит нас к конструкции, эквивалентной схеме Лакса-Фридрихса. Важнейшим свойством схемы является ее абсолютная робастность, компенсируемая повышенной диссипативностью. В работе мы предлагаем использовать кусочно-параболическую реконструкцию физических переменных, что позволяет получить простую абсолютно робастную схему высокого порядка точности на гладких решениях и с малой диссипацией на разрывах. Верификации на специальном наборе тестов и на задаче об эволюции релятивистской струи подтверждают такие свойства построенной схемы.
The Lax-Friedrichs scheme is traditionally considered an alternative to the Godunov scheme, since it does not require solving the Riemann problem. In the equations of special relativistic hydrodynamics, the speed of light is a natural limitation of the wave propagation speed. The use of such an upper estimate of the slopes of characteristics in the schemes of Roe, the Rusanov type, or the Harten-Lax-Van Leer family leads to a construction equivalent to the Lax-Friedrichs scheme. Due to the absolute robustness of the scheme, a number of software implementations have been developed on its basis for modeling relativistic gas flows. In this paper, we propose a piecewise parabolic reconstruction of the physical variables to reduce dissipation of the numerical method. The use of such a reconstruction in the Lax-Friedrichs scheme allows us to obtain an absolutely robust simple scheme of high-order accuracy on smooth solutions and with small dissipation at the discontinuities. The computational experiments carried out in the article confirm these properties of the scheme.
