AimsPrecise implant positioning, tailored to individual spinopelvic biomechanics and phenotype, is paramount for stability in total hip arthroplasty (THA). Despite a few studies on instability prediction, there is a notable gap in research utilizing artificial intelligence (AI). The objective of our pilot study was to evaluate the feasibility of developing an AI algorithm tailored to individual spinopelvic mechanics and patient phenotype for predicting impingement.MethodsThis international, multicentre prospective cohort study across two centres encompassed 157 adults undergoing primary robotic arm-assisted THA. Impingement during specific flexion and extension stances was identified using the virtual range of motion (ROM) tool of the robotic software. The primary AI model, the Light Gradient-Boosting Machine (LGBM), used tabular data to predict impingement presence, direction (flexion or extension), and type. A secondary model integrating tabular data with plain anteroposterior pelvis radiographs was evaluated to assess for any potential enhancement in prediction accuracy.ResultsWe identified nine predictors from an analysis of baseline spinopelvic characteristics and surgical planning parameters. Using fivefold cross-validation, the LGBM achieved 70.2% impingement prediction accuracy. With impingement data, the LGBM estimated direction with 85% accuracy, while the support vector machine (SVM) determined impingement type with 72.9% accuracy. After integrating imaging data with a multilayer perceptron (tabular) and a convolutional neural network (radiograph), the LGBM’s prediction was 68.1%. Both combined and LGBM-only had similar impingement direction prediction rates (around 84.5%).ConclusionThis study is a pioneering effort in leveraging AI for impingement prediction in THA, utilizing a comprehensive, real-world clinical dataset. Our machine-learning algorithm demonstrated promising accuracy in predicting impingement, its type, and direction. While the addition of imaging data to our deep-learning algorithm did not boost accuracy, the potential for refined annotations, such as landmark markings, offers avenues for future enhancement. Prior to clinical integration, external validation and larger-scale testing of this algorithm are essential.Cite this article: Bone Jt Open 2024;5(8):671–680.

Published: August 2024

BackgroundStrengthening workforce management to address retention challenges is worldwide concern. Ethiopia did different human resource reforms to improve retention and performance of available health workforce to step up towards universal health coverage. However, there is limited and fragmented research on intention to leave their current facility and related factors on health workers. This review was done to assess pooled national prevalence of intention to leave their current health facility and related factors among Ethiopian health workers.MethodsThis systematic review and meta-analysis followed PRISMA guidelines. Authors prepared a review protocol per Joanna Briggs Institute (JBI) manual for evidence synthesis and got registered from PROSPERO for transparency. The authors conducted a comprehensive search of PubMed, Web of Science, Cochrane, Google Scholar and African Index Medicus databases and grey literature like WHO library from 8 June 2022 to 30 May 2023. Pooled prevalence of intention to leave current health facility and related factors was computed using MedCalk, Meta Essentials and R software. Publication bias was assessed using Egger’s test and a funnel plot.ResultsPooled prevalence of intention to leave among health workers in Ethiopian healthcare setting was found to be 63.52% (95% CI (58.606–67.904)) for random effects model at Q = 141.5689 (I2(inconsistency) = 90.82%, P < 0.0001). Only organizational justice OR = 0.29 (0.14–0.61) was found to be a significantly associated factor for health workers’ intention to leave their current healthcare setting in Ethiopia.ConclusionMore than 6 in 10 of the health workers in Ethiopia were ready to leave their current healthcare facility. This result was higher than studies done in other parts of the world, even in African countries. The associated factor for health workers’ intention to leave their current health facility was only organizational justice. So, health authorities should improve their organizational justice to retain their employees.

Background
Urogenital schistosomiasis caused by Schistosoma haematobium is highly endemic in the municipality of Cubal in Angola. Currently, diagnosis is based on the observation of S. haematobium eggs in urine samples by microscopy but this method has low sensitivity. Few studies have been performed using molecular techniques in high-prevalence areas for the detection of S. haematobium. The objective of this study is to evaluate the usefulness of real-time PCR as a diagnostic technique for urogenital schistosomiasis among preschool-age children and its correlation with morbidity data.

Methods
A cross-sectional study was conducted in Cubal, Angola, involving 97 urine samples from preschool-age children analyzed by the dipstick test, microscopic examination of filtered urine, and real-time PCR. The diagnosis of urogenital schistosomiasis was based on microscopy and/or real-time PCR results. Clinical and ultrasonography evaluation was performed to rule out complications of schistosomiasis.

Results
We detected a total of 64.95% of samples positive by real-time PCR and 37.11% by microscopy. The sensitivity of parasitological diagnosis of urogenital schistosomiasis by real-time PCR and microscopy was 95.45% and 54.55%, respectively, and the sensitivity of real-time PCR compared with microscopy was 91.67%. A positive real-time PCR result was significantly related to older age (mean = 3.22 years), detection of eggs by microscopy, and abnormal urine dipstick results (18.56% with proteinuria, 31.96% with leukocyturia, and 31.96% with microhematuria) (p-value<0.05). Ultrasound analysis showed that 23.94% of children had urinary tract abnormalities, and it was significantly related to the real-time PCR diagnosis (p-value<0.05).

Conclusions
Real-time PCR is a more sensitive technique than microscopy for urinary schistosomiasis diagnosis in preschool-age children in Cubal. This increase in sensitivity would allow earlier diagnosis and treatment, thus reducing the morbidity associated with schistosomiasis in its early stages.

Published: August 2024

Background
In the United States, there has been a concerning rise in the prevalence of opioid use disorders (OUD) among transition-age (TA) adults, 18 to 25-years old, with a disproportionate impact on individuals and families covered by Medicaid. Of equal concern, the treatment system continues to underperform for many young people, emphasizing the need to address the treatment challenges faced by this vulnerable population at a pivotal juncture in their life course. Pharmacotherapy is the most effective treatment for OUD, yet notably, observational studies reveal gaps in the receipt of and retention in medications for opioid use disorder (MOUD), resulting in poor outcomes for many TA adults in treatment. Few current studies on OUD treatment quality explicitly consider the influence of individual, organizational, and contextual factors, especially for young people whose social roles and institutional ties remain in flux.

Methods
We introduce a retrospective, longitudinal cohort design to study treatment quality practices and outcomes among approximately 65,000 TA adults entering treatment for OUD between 2012 and 2025 in New York. We propose to combine data from multiple sources, including Medicaid claims and encounter data and a state registry of substance use disorder (SUD) treatment episodes, to examine three aspects of OUD treatment quality: 1) MOUD use, including MOUD option (e.g., buprenorphine, methadone, or extended-release [XR] naltrexone); 2) adherence to pharmacotherapy and retention in treatment; and 3) adverse events (e.g., overdoses). Using rigorous analytical methods, we will provide insights into how variation in treatment practices and outcomes are structured more broadly by multilevel processes related to communities, treatment programs, and characteristics of the patient, as well as their complex interplay.

Discussion
Our findings will inform clinical decision making by patients and providers as well as public health responses to the rising number of young adults seeking treatment for OUD amidst the opioid and polysubstance overdose crisis in the U.S.

Introduction
Breast cancer poses a significant health challenge in Sub-Saharan Africa, particularly in Ghana, where late-stage diagnoses and limited healthcare access contribute to elevated mortality rates. This study focuses on the crucial role of pathology and laboratory medical (PALM) services in the timely diagnosis of breast cancer within Ghana.

Methods
A cross-sectional survey of hospitals was completed from November 2020 to October 2021, with 94.8% of identified in-country hospitals participating. Pathology service-related parameters assessed included whether pathology was available for the diagnosis of breast cancer on-site or via external referral, the number of pathology personnel, additional breast cancer diagnostic capabilities including estrogen and progesterone and/or HER2 testing, and the time from biopsy to patients receiving their results. Geospatial mapping was used to identify areas of limited access.

Results
Of the 328 participating hospitals, 136 (41%) reported breast cancer pathology services, with only 6 having on-site capabilities. Pathology personnel, comprising 15 consultants and 15 specialists, were concentrated in major referral centers, particularly in Greater Accra and Kumasi. An assessment of referral patterns suggested that 75% of the population reside within an hour of breast cancer pathology services. Among the 136 hospitals with access to breast cancer pathology, only a limited number reported that results included ER/PR (38%) and HER2 testing (33%).

Conclusion
Ghana has been able to ensure significant pathology service availability through robust referral pathways with centralized labs. Despite this, difficulties persist with the majority of pathology results not including hormone receptor testing which is important in providing tumor specific treatment.

Published: August 2024

Abstract
The Reeves’ muntjac Muntiacus reevesi is an ungulate native to China and Taiwan that has been released into the wild in several continental European countries and the United Kingdom. We present recent records of the species in mainland France. We also investigated the dispersal rate and density of the established population in the Centre-Val de Loire region. The number of observations of M. reevesi was low in the period 2008–2016, increased sharply until 2019 and then decreased until 2023. From a comparison between the distribution in 2008–2012 and 2013–2017, the dispersal rate was estimated at an average of 3.2 km/year, and 7.6 km/year between 2013–2017 and 2018–2023. Based on a camera trap protocol, the population density was assumed to be very low in forested areas but estimated with a lack of robustness due to a single observation. Further efforts must be made to better assess the risk of an increase in the wild population of Reeves’ muntjac in the Centre-Val de Loire region. To prevent potential impacts, rapid control measures can be put in place in the large area (10,800 km2) where muntjacs are now rapidly spreading.
Intervals of posets of a zero-divisor graph
Authors: LaGrange John D. 
Published: August 2024

Abstract
This article is concerned with bounded partially ordered sets P such that for every p ∈ P ∖ {1} there exists q ∈ P ∖ {0} such that 0 is the only lower bound of {p, q}. The posets P such that P ≅ Q if and only if P and Q have isomorphic zero-divisor graphs are completely characterized. In the case of finite posets, this result is generalized by proving that posets with isomorphic zero-divisor graphs form an interval under the partial order given by P ≲ Q if and only if there exists a bijective poset-homomorphism P → Q. In particular, the singleton intervals correspond to the posets that are completely determined by their zero-divisor graphs. These results are obtained by exploring universal and couniversal orderings with respect to posets that have isomorphic zero-divisor graphs.

Published: August 2024

Abstract
For normalized starlike functions f : 𝔻 → ℂ, we consider the analytic functions g : 𝔻 → ℂ defined by g(z) = (1 + z(f″(z))/f′(z))/(zf′(z)/f(z)) and g(z) = (1 − α)(zf′(z))/f(z) + α(1 + (zf″(z))/f′(z)), 0 ≤ α ≤ 1. We determine the largest radius ρ with 0 < ρ ≤ 1 such that g(ρ z) is subordinate to various functions with positive real part.
A new family of copulas based on probability generating functions
Authors: Zachariah Swaroop Georgy , Arshad Mohd. , Pathak Ashok Kumar 
Published: August 2024

Abstract
We propose a method to obtain a new class of copulas using a probability generating function (PGF) of positive-integer valued random variable. Some existing copulas in the literature are sub-families of the proposed copulas. Various dependence measures and invariant property of the tail dependence coefficient under PGF transformation are also discussed. We propose an algorithm for generating random numbers from the PGF copula. The bivariate concavity properties, such as Schur concavity and quasi-concavity, associated with the PGF copula are studied. Two new generalized FGM copulas are introduced using PGFs of geometric and discrete Mittag-Leffler distributions. The proposed two copulas improved the Spearman’s rho of FGM copula by (−0.3333, 0.4751) and (−0.3333, 0.9573). Finally, we analyse a real dataset to illustrate the practical application of the proposed copulas.

Este artigo tem por objetivo explorar os conceitos de memória de trabalho e atitudes comportamentais de crianças com deficiências ou baixos índices nessa memória. Foram selecionados estudos que pesquisam essas características em crianças em idade escolar. As habilidades cognitivas que nos interessam aqui são as seguintes: desempenho acadêmico em leitura e vocabulário. Em relação ao comportamento,interessa-nos o comportamento em sala de aula. As pesquisas, especialmente de Alloway(2009) e colaboradores, defendem que crianças com baixos índices de memória de trabalho travam verdadeiras batalhas para conseguir alcançar um desempenho acadêmico aceitável. Mesmo assim, seu desempenho é abaixo da média das criançascom índices normais de memória de trabalho e, infelizmente, a maioria dos professores não identificam essas dificuldades como relacionadas à capacidade de memória de trabalho. Normalmente, tais dificuldades são atribuídas a outros fatores, como falta de concentração e hiperatividade.

В статье рассмотрены целесообразность и предпосылки формирования новой модели развития Сибири, даны понятия национальной и региональной моделей развития. Показаны особенности и сформулированы направления реализации модели развития Сибири в условиях адаптации к вызовам и угрозам последнего времени, в том числе выделены пять типов маневрирования и приспособления к новым условиям развития: структурный маневр, транспортно-логистический маневр, управленческий маневр, научно-технологический маневр, пространственный маневр. Рассмотрены контуры новой модели развития Сибири, которая может быть реализована в период перехода на траекторию возобновляющегося экономического роста России с его высоким качеством. Предложены шесть векторов - основополагающих принципов и направлений реализации такой модели, главными из которых являются переход на модель возобновляющегося роста социальной ценности, усиление связности пространства Азиатской России и формирование новой системы трансграничных взаимодействий. Исходя из анализа Основных положений XIV пятилетнего плана народно-хозяйственного и социального развития КНР и перспектив до 2035 года показано, что Китай в своих стратегических планах фактически ориентирован на такую модель развития. В заключение дана оценка реалистичности предлагаемой модели развития Сибири.
The article delves into the necessity and underlying factors contributing to the formulation of a novel development model for Siberia. It provides definitions and concepts on both national and regional development models. The features and strategies for implementing Siberia's development model under the current challenges and recent threats are outlined, which include five distinct types of maneuvers and adaptations to new development conditions: structural, transport and logistics, managerial, scientific and technological, and spatial maneuvers. We consider the contours of this prospective model for Siberia's development, specifically examining its viability during a transition towards a trajectory of Russia's renewable economic growth characterized by high quality. Six key vectors, representing fundamental principles and directions for such a model, are proposed. Among these, the most dominant are the shift towards a social value model of renewable growth, bolstering the connectivity of Asian Russia's space, and the establishment of a novel system for cross-border interactions. Drawing insights from the analysis of “The Outline of the 14th Five-Year Plan for Economic and Social Development and Long-Range Objectives through the Year 2023 of the People's Republic of China," the study illustrates that China's strategic plans practically align with such a development model. The conclusion offers an assessment of the feasibility of the proposed model for Siberia's development.

Published: August 2024

AbstractThere are increasing number of clinical cases with physician-modified endograft (PMEG) endograft for urgent reconstruction of large pararenal aneurysms to reduce the perioperative complication risks of fragile patients, but the risk of spinal cord ischemia due to the coverage of longer segment of thoracic aorta is relatively high.We demonstrate an expedited endovascular treatment of an 88 mm pararenal aneurysm by performing a 4-vessel fenestrated endovascular aortic repair. A prominent Adamkiewicz artery, ectatic supraceliac aortic segment, median arcuate ligament compression of the celiac artery and severe tortuosity of the common iliac arteries made the endovascular repair more challenging. A PMEG was implanted with simultaneous deployment technique to achieve a short proximal landing zone to preserve the Adamkiewicz artery.The proper risk assessment and preparation of the patient based on the clinical evaluation and procedure planning is essential for the clinical success of PMEG in urgent indication.
