Objectives:
To examine citrate anticoagulation in continuous renal replacement therapy (CRRT) in the PICU.

Design:
Post hoc analysis of a curated, multicenter dataset collected from January 1, 2022, to June 1, 2023.

Setting:
Seven PICUs in Turkey.

Patients:
PICU admissions in need of CRRT, 28 days to 18 years old.

Interventions:
None.

Measurements and Main Results:
In 128 filters used in 73 patients, the effective filter life (EFL) restricted to 72 hours was a median (interquartile range [IQR]) of 40.5 hours (IQR, 21–58 hr); total EFL was a median of 59 hours (IQR, 28–89 hr). Analysis of the receiver operating characteristic curve for initial citrate infusion dose (CID) and whether EFL reached 72 hours identified a cutoff level for initial CID of greater than 2.64 mmol citrate per liter of patient blood flow (mmol/L-bf). As expected, the two filter groups categorized by initial CID (≥ 2.7 vs. < 2.7 mmol/L-bf) showed filters in children receiving higher initial dosing had longer total EFL (72 hr [IQR, 48–104 hr] vs. 38.5 hr [IQR, 18–84 hr]; p = 0.03). We failed to identify an association between CRRT for over 24 or 48 hours and greater odds (odds ratio [OR], 95% CI) of citrate accumulation (OR, 2.23; 95% CI, 0.82–6.13; p = 0.118 or OR, 1.78; 95% CI, 0.84–3.8; p = 0.134, respectively). However, we cannot exclude up to 6.1- or 3.8-fold odds of citrate accumulation; of note, CRRT over 72 hours was associated with greater odds of citrate accumulation (OR, 2.17; 95% CI, 1.01–4.68; p = 0.04). Citrate lock syndrome occurred in eight of 128 (6.3%; 95% CI, 3–11.4%) filters, and resolved without termination of CRRT. On multivariable analysis, a higher patient initial lactate concentration was associated with an 18% (95% CI, 7–30%) greater hazard of developing citrate accumulation.

Conclusions:
Citrate anticoagulation for CRRT is an option for children. Choosing an initial CID greater than or equal to 2.7 mmol/L-bf provides longer EFL but with the associated potential of citrate accumulation. Further studies are needed on initial CID and duration of EFL.
Gender and Age Differences in Corpus Callosum Morphology: High-Altitude Adaptations in Native Tibetan Populations
Authors: Zeng Ke , Wang Zhan-fei , Su Ming-ran , Wang Yu , Zhang Zhi-ying , Zhong Hua 
Published: December 2024

Background and Aims:
The corpus callosum is recognized as the largest interhemispheric white matter structure, coordinating distinct functions of the brain. High-altitude environments may influence the structure of the corpus callosum. This study aims to evaluate the morphologic characteristics of the corpus callosum in Tibetans residing on the Qinghai-Tibet Plateau while investigating the effects of sex, age, and high-altitude exposure on its morphology.

Materials and Methods:
The study comprised 262 healthy native Tibetan adults, including 113 men and 149 women. The length, height, area, and thickness of each subregion of the corpus callosum were measured, with the data normalized according to brain length and mid-sagittal cortical brain area. Statistical analyses were conducted utilizing nonparametric tests and partial correlation analysis.

Results:
Most normalized morphologic measurements indicated significant sex differences, particularly in the thickness of the rostrum (z=−3.199, P=0.001), genu (z=−3.133, P=0.002), body (z=−3.612, P<0.001), splenium (z=−2.279, P=0.02), and callosal length (z=−2.722, P=0.006), and area (z=−2.179, P=0.03). The callosal area (R
2=0.084, P<0.001) demonstrated an inverted U-shaped trajectory throughout the lifespan, peaking at ∼40 years of age.

Conclusions:
This study identified pronounced sex differences in the corpus callosum morphology among Tibetans. Despite living at high altitudes, the age-related trajectory of the callosal area resembled patterns observed in other populations, although peak ages differed by sex.
Are Bone Expansion Techniques Effective for Implant Placement in Narrow Alveolar Ridges?
Authors: Rizk Omar , Ashraf Sherif , Zaki Ahmed Hany , AbdelMohsen Karim Mohamed 
Published: December 2024

Because of the fact that sufficient alveolar ridge bone is essential for the success of implant placement, the authors often face a challenge with augmenting residual maxillary alveolar ridges. The aim of the study was to compare the amount of ridge gain by the Osseodensification method with the manual bone expanders method for healed edentulous sites in the maxilla at different time intervals (immdiate postoperative and 6 mo postoperative). Two groups were equally and randomly divided with a total of 14 implants (Biohorizons) placed in the maxillary arch for 8 patients, osseodensification was used for 1 group (group 1), whereas manual threaded expanders (bone spreaders) was used for the other group (group 2). Results suggest that the expanders group (group 2) yielded greater immediate postoperative expansion at some points along the length of placed implants; however, most of the expansion gain at the immediate Post-operative stage underwent continuous remodeling 6 months postoperative. The authors recommend using expansion techniques only when other more predictable techniques for horizontal bone augmentation are not feasible.
Interactive relationships among factors influencing skilled labor shortages in the construction industry
Authors: Kuo Yao-Chen 
Published: December 2024

PurposeThe factors contributing to skilled labor shortages in the construction industry are investigated based on relevant global literature. The potential factors are collected, organized and subjected to expert evaluation to determine their inter-relationships. The identified factors are integrated to determine both direct and indirect impacts, clarifying their relative importance.Design/methodology/approachApart from literature reviews, the decision-making trial and evaluation laboratory (DEMATEL) method was employed to elucidate influential relationships among the factors. Intuitive assessments and DEMATEL with and without the shortage factors were used to compare the impact of various factors on skilled labor shortages.FindingsSignificant differences were observed between considering only direct effects and both direct and indirect effects. Factors identified through comprehensive evaluation were prioritized; poor overall wages, poor overall welfare and lack of retirement income security and unclear career path owing to lack of prospects and talent plans were the three important factors identified.Research limitations/implicationsThe disparity between construction companies and key stakeholders, such as government agencies, public sector clients, pre-project planners, designers and consulting engineers, stems from differing priorities concerning skilled labor in the construction industry. In this study, evaluations of most experts from construction companies and the gap ratio for data reliability were implemented for the analysis. In the future, more experts from government agencies, and other groups should be included while focusing on the shortage in individual trades of skilled workers. In addition, the proposed measures require further evaluation for interactive influence and effectiveness.Originality/valueThe interactive relationship among the factors influencing skilled labor shortages is explored to determine measures to alleviate their influence. This can aid policymakers in identifying effective solutions.
Decoupling from Chinese technology? Navigating current trends in Sino-European service relations
Authors: Cieślik Ewa 
Published: December 2024

PurposeThe article focuses on cross-sectoral analysis concerning services, especially ICT services, flowing from China to European manufacturing. The aim of the study is to analyse Sino-European relations in terms of ICT servicification. The article attempts to answer the following questions: does China’s relationship with Europe in terms of the servicification of manufacturing align with global servicification trends? Have global economic shocks, such as decoupling policies, diminished the flows of Chinese ICT services in European advanced manufacturing sectors?Design/methodology/approachThis study employed input–output models to analyse the increasing role of China as a supplier of ICT services to European manufacturing. It also identified the industries that are most dependent on Chinese ICT services.FindingsThe analysis highlights the increasing reliance of European manufacturing on Chinese ICT services, with a notable rise across both Western Europe and CEE. This dependency is particularly strong in advanced sectors such as automotive and electronics, and there is no evidence of decoupling from China, even amidst global shocks or geopolitical tensions like the Trump presidency. Additionally, the BRI had limited direct impact, as the servicification trends appear driven more by broader globalization processes.Originality/valueThe study investigates all European countries and their manufacturing sectors’ reliance on Chinese services. It concentrates on services related to high technology, specifically ICT. Moreover, the previous research has focused on servicification of manufacturing, in general, neglecting industry-specific analysis. It contributes to the literature by providing insights into the relationships between developing and developed economies in terms of GVCs in the context of digital servicification and decoupling conditions.

Authors: Wang Liecheng , Zhang Min , Guo Hangfei 
Published: December 2024

Purpose
Small and medium-sized enterprises (SMEs) are critical for achieving a green economy. This study aims to empirically explore business associations’ impacts on SMEs’ green transformation in China.

Design/methodology/approach
This study uses a multiple-case study approach. The authors collect data from four Chinese business associations and their members.

Findings
This study finds that business associations promote SMEs’ green transformation by providing individual and collective services. SMEs conduct green transformation by developing a green mindset and adopting green operations. The results show that individual services directly enhance members’ green mindset and green operations. Collective services promote members’ green mindset and green operations both directly and indirectly by building relational capital.

Originality/value
This study contributes to the literature by revealing that business associations play critical roles in assisting SMEs’ green transformation. In addition, this study suggests that SMEs may adopt different practices compared with large companies. The findings enhance the current understanding of how SMEs conduct green transformation and how business associations assist SMEs.
Improving a frontier approach to selecting suppliers for a make-to-order supply chain
Authors: Tarpey Richard , Yang Chenchen , Yang Feng , Yuan Qianqian , Yue Jinfeng 
Published: December 2024

Purpose
Make-to-order (MTO) manufacturers often receive lead time-sensitive orders requiring multiple custom parts not commonly in stock. These irregular orders can be challenging to manage across numerous suppliers, resulting in high costs and associated risks in completing orders on time. Many MTO manufacturers develop relationships with multiple sourcing suppliers, spreading risk and ensuring delivery performance at a reasonable cost. These relationships, however, result in an order allocation problem. The purpose of this study is to consider previously proposed frontier portfolio solution methodologies used in sourcing selection and improve upon an identified weakness to improve the evaluation and selection of order quantities across multiple suppliers.

Design/methodology/approach
This paper analyzes an existing frontier portfolio selection model where potentially inefficient portfolios are selected and considered. The authors propose introducing a data envelopment analysis (DEA) technique paired with the frontier portfolio selection model to eliminate inefficient portfolios from being considered to help MTO manufacturers determine allocations by calculating and evaluating two factors: on-time probability and associated cost.

Findings
While previously proposed frontier models provide mechanisms to allocate orders across different suppliers to meet variable service levels and costs, this study finds model improvements to eliminate inefficient portfolios to facilitate better decisions for order allocation. This study finds a more efficient potential solution using a frontier method paired with DEA to help the MTO manufacturer select sourcing partners and determine the associated quantity allocation for each chosen supplier. The technique provides flexibility, resulting in a range of options to solve the dilemma with differing emphasis on due dates and costs.

Practical implications
The proposed method provides a pool of more efficient frontier portfolios ranging from higher on-time probability and higher cost to less on-time likelihood and lower cost, resulting in less chance of an inefficient portfolio choice. Such a design ensures that regardless of the preference and specific need criteria (cost versus on-time delivery), MTO manufacturers have flexibility in choosing an optimal solution.

Originality/value
This paper extends an existing model of supplier selection to improve selection quality based on a DEA technique to remove inefficient portfolios.
Plant–soil feedback drives the ‘nursing effect’ on Sitka spruce
Authors: Zhou Yichen , Tao Tingting , Cox Filipa , Johnson David 
Published: December 2024

Abstract

The productivity of economically valuable focal trees in mixtures is often improved by inclusion of lower‐value nursing species, but the mechanisms underpinning such effects are poorly resolved. This gap in understanding limits the capacity to develop efficient planting strategies for forests and woodlands to contribute to net‐zero and other critical ecosystem functions.

Here, we undertook a plant–soil feedback experiment to test the hypothesis that feedback effects improve the biomass of Sitka spruce [Picea sitchensis (Bong.) Carr] in soil conditioned by monocultures of heterospecific nurse species, and a mixture comprising Sitka spruce and heterospecifics, compared to soil conditioned by only Sitka spruce.

Sitka spruce saplings had greater biomass in soil conditioned by Scots pine monocultures (Pinus sylvestris L.) and the mixture compared to their own soil or soil conditioned by silver birch (Betula pendula Roth). Statistical models showed that colonization of ectomycorrhizal fungi on tree roots in the feedback phase was positively related to seedling biomass, and significantly influenced plant growth strategy.

Soil inorganic nitrogen concentrations were strongly affected by monocultures and mixtures in the conditioning phase, but these effects were not related to biomass of seedlings in the feedback phase. However, the positive associations among microbial biomass nitrogen, extractable ammonium in soil, and the activity of the nitrogen‐degrading enzyme N‐acetylglucosaminidase may influence seedling biomass in the longer‐term by stimulating nitrogen cycling.

Synthesis and applications. Our findings show that in the crucial early phases of tree growth, plant–soil feedback plays an important role in shaping productivity of Sitka spruce and the nitrogen cycle in forest soils, the latter which may have important consequences for tree biomass in the longer‐term. Our findings demonstrate the importance of the nursing effect in the early stages of plant growth and provide a mechanistic explanation both for long‐held observations of nursing effects in forestry systems and for biodiversity effects in natural woodlands. The nursing effect was largely driven by the activity of symbiotic ectomycorrhizal fungi, and therefore it is important for practitioners to ensure nursing species monocultures or mixtures support ectomycorrhizal fungi that are compatible with high‐value target species.
Detrital Zircon U‐Pb Dating for Clastic Rocks from Boreholes in the Eastern Junggar Basin: Constraints on Permian Tectonics in the Southern Central Asian Orogenic Belt

Published: December 2024

AbstractPermian sedimentary successions, widely distributed in the eastern Junggar Basin, may record key details on the closure of the Paleo‐Asian Ocean in this region. Results of boreholes show that Permian strata is mainly composed of mudstone, sandy mudstone, siltstone, sandstone, sandy conglomerate, dolomite, and limestone. Detrital zircon U‐Pb dating results of three sandstone samples yielded the calculated maximum ages of 296 Ma, 278 Ma and 293 Ma, indicating they possibly deposited during the Early Permian. Permian strata in the eastern Junggar Basin show similar rock associations and detrital zircon age data distribution patterns. Our new and compiled age data for sandstone samples in the eastern Junggar Basin and Bogda region yield predominant Paleozoic ages, close to their sedimentary ages. Such detrital zircon age data distribution patterns support the hypothesis that these Early Permian meta‐clastic rocks in the eastern Junggar Basin and Bogda region were deposited in a subduction‐related basin, and indicate an Early Permian Ocean prevented Precambrian detritus from the Central Tianshan block from depositing in the eastern Junggar Basin and Bogda region.
Numerical Study on the Mechanical Behavior of Hydraulic Fractures under Stress Disturbance, based on a Multi Pb‐GBM Method
Authors: LI Guang , LIU Shuaiqi , MA Fengshan , GUO Jie , HUI Xin 
Published: December 2024

AbstractWater inrush is a common disaster in submarine mining. The key to preventing this disaster is to restrict the water‐conducting fissure propagation induced by mining from forming a flow channel to communicate with the overlying aquifer. The mechanical behavior of hydraulic fractures under stress disturbance lies at the heart of the problem. Hence, the multiple parallel bond—grain‐based model (multi Pb‐GBM) is introduced to explore the hydraulic fracture evolution law of crystalline granite under the influence of stress disturbance. The results show that: hydraulic fracturing under stress disturbance is clearly affected by the stress wave frequency; the higher the frequency is, the more difficult it is to crack, but the crack propagation speed is faster after crack initiation; the propagation direction of a crack is deflected towards the propagation direction of the stress wave and the crack dip angle is controlled by the maximum principal stress; the internal crystal boundary of the same mineral is the most stable one among the three contacts, the contact boundary between different minerals being the most fragile one. This research not only has a practical application value to seabed mining engineering, but also has important theoretical significance in enriching deep rock mechanics theory.

Published: December 2024

AbstractFracture effectiveness plays a key role in gas productivity of ultra‐deep tight sandstone reservoirs, Kuqa depression, Tarim Basin. Based on cores, thin sections, well logging, well testing and production data, the study evaluated fracture effectiveness and illustrated its impacts on gas productivity. High‐angle and vertical shear fractures are the most important types. Distribution of effective fractures shows great heterogeneous. Fracture effectiveness is influenced by tectonism, diagenesis and in‐situ stress. Earlier fractures or fractures in close to gypsum rock are easier to be filled. Completely filled fractures can be reopened under late tectonism. Dissolution improves local fracture effectiveness. Minerals spanning fracture surfaces protect fracture effectiveness from late compression. Fractures filled with calcite can be activated by acidification. Effective fractures parallel to maximum horizontal principal compressive stress direction show larger aperture. Overpressure can decrease the effective normal stress to maintain fracture effectiveness. With exploitation, decline in pore pressure reduces fracture effectiveness. Linear density, aperture, and strike of effective fractures influence gas productivity. Effective fractures greatly enhance matrix permeability. Therefore, more abundant and larger aperture fractures are always corresponded to higher productivity. However, effective fractures also facilitate late water invasion, especially, both mutually parallel. Intense water invasion leads to rapidly declines in productivity.
Comparison of balloon catheter and oral misoprostol for cervical ripening in women with pre‐labor rupture of membranes: A Finnish randomized controlled trial
Authors: Kruit Heidi , Rahkonen Leena 
Published: December 2024

AbstractIntroductionPre‐labor rupture of membranes (PROM) occurs in about 8% of term pregnancies with over 70% delivering spontaneously within 24 h. However, prolonged PROM increases the risk of chorioamnionitis and neonatal sepsis. While misoprostol and oxytocin are considered safe and effective methods of labor induction, most guidelines do not encourage balloon catheter (BC) use following PROM given concerns about increased risk of chorioamnionitis. However, lack of robust evidence exists. This study aimed to compare BC and low‐dose oral misoprostol (OM) regarding infectious morbidity and assess the impact of routine antibiotic prophylaxis during BC use on infection prevention.Material and MethodsA randomized controlled trial comparing BC and low‐dose 25 μg OM for pre‐induction cervical ripening in an inpatient setting and assessing the preventive effect of prophylactic antibiotics during BC use in 175 women with PROM was carried out between 1.2.2021 and 31.12.2023 in Helsinki University Hospital. The study protocol was registered in the ISCTN registry (ISRCTN10972090). The primary outcome measures of the study were the mode of delivery, and maternal and neonatal infections.ResultsEighty‐nine women (50.9%) were allocated in the BC arm and 86 women (49.1%) in the OM arm. The cesarean delivery rates were comparable (BC 19.1% [n = 17] vs. OM 11.6% [n = 10]; p = 0.17). The rate of chorioamnionitis (BC 9.1% [n = 8] vs. OM 3.5% [n = 3]; p = 0.21) or neonatal infection (BC 4.5% [n = 4] vs. OM 2.3% [n = 2]; p = 0.68) were not statistically significantly different between the groups, although there was a trend towards higher frequency of infections in the BC arm. There were no differences in the incidence of chorioamnionitis or neonatal infections when routine antibiotic prophylaxis was administered during the BC use compared to those who did not receive antibiotics (chorioamnionitis 10.9% with antibiotics vs. 8.0% without antibiotics; p = 0.68, and neonatal infection 5.3% vs. 3.9%; p = 1.00). Maternal childbirth satisfaction was similar in the BC and OM groups.ConclusionsOur results showed almost threefold frequency of chorioamnionitis and twofold frequency of neonatal infections following the use of BC compared to OM, although the study was underpowered for reaching statistical significance. The use of prophylactic antibiotics during BC retention did not reduce the incidence of infections.
