Authors: Jorquera René , Melibosky Francisco , Villavicencio Aldo , Azócar Camila , Corvalán Gonzalo , Ramírez Paula , Paz Agustín 
Published: January 2024

AbstractComminuted fractures involving the metacarpophalangeal joint are a real challenge for the hand surgeon due to the complexity of their management and the high frequency of functional sequelae caused by the incongruence of the joint surfaces and the injury of soft tissues requiring repair. Metacarpophalangeal joint arthroscopy is an emerging and useful tool for the upper extremity surgeon allowing assisted reduction and percutaneous fixation of these fractures since it permits a complete evaluation of the joint fragments and enables precision in the reduction with the advantage of being a minimally invasive and safe technique. This technique was performed in two patients with complex fractures of the metacarpophalangeal joint with good functional results. In conclusion, this technique is reproducible, with good results and minimal soft-tissue morbidity. It allows a stable osteosynthesis, enabling early joint mobility and rehabilitation, which is essential for function recovery.

Authors: Chow Esther Ching San 
Published: January 2024

Abstract
Background The thumb carpometacarpal joint (CMCJ) osteoarthritis is one of the most common pathologies in the hand with controversial treatment options.
Description of Technique Describe the use of arthroscopic technique for thumb CMCJ arthrodesis and the clinical outcome.
Patients and Methods Cases with Eaton III thumb CMCJ osteoarthritis treated with arthroscopic arthrodesis were reviewed. Patient evaluations include: grip strength, pinch strength, range of motion, Kapandji score, Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, and the visual analog scores for pain. All cases were assessed before the surgery and at 3, 6, 12, and 24 months after surgery. Radiographs were reviewed.
Results There were total 16 patients with 18 arthrodesis performed. The average age was 62.2 years with M:F ratio of 2:7. The average follow-up time was 57.2 months. There was improvement of pain score as early as at postop 3 months (p < 0.001) and continued to improve at 6, 12, and 24 months. There was improvement of grip strength and pinch strength at 12 and 24 months (p < 0.001). The DASH score showed improvement as early as at 3 months (p = 0.012). There was a reduction of Kapandji score and interphalangeal joint motion at 3 months postop, but these returned to normal at 6 months. There was no major complication. There was one case of nonunion (5.6%).
Conclusion Arthroscopic arthrodesis is a feasible treatment option and provides excellent pain relief, restore thumb strength and stability, retain functional thumb mobility, and hence improvement in hand function.

Published: January 2024

Abstract
Background Four corner fusion (4CF) can be performed using various techniques, each with its own efficacy and complication profile. Kirschner wires (K-wires) are a reliable and cost-effective method when performing 4CF.
Purpose The purpose of this study was to determine the union rate and complication profile of utilizing K-wires when performing a 4CF.
Methods A retrospective chart review was performed studying patients who underwent 4CF from a multisurgeon, single-institution database. Demographic data were collected, and functional outcomes were recorded including wrist range of motion (ROM), fusion rates, time to fusion, and complication rates. Continuous variables were compared via two-tailed t-tests, numerical data via one-way analysis of variance tests, and categorical data via Fisher's Exact test.
Results In total, 141 patients underwent 4CF with K-wire fixation with an overall nonunion rate of 3.5% (5/141). Diabetics had a nonunion rate of 11% compared to 3% without diabetes (p = 0.28). Wrist ROM was significantly greater in patients who achieved bony union at 6 weeks after removal of hardware compared to the nonunion group (78.0 degrees ± 14.4 vs. 57.8 degrees ± 21.3, p < 0.05). There was no difference in wrist ROM between the two groups six months after hardware removal. There were no pin-related complications that required revision surgery.
Conclusion 4CF utilizing K-wire fixation is a reproducible and cost-effective technique that results in good patient outcomes including bony union and functional wrist ROM. Smoking and diabetes did not significantly increase the risk of nonunion, and K-wire fixation can successfully be used in these patient populations.

Published: January 2024

Abstract
Introduction Patient-reported outcome measures (PROMs) can be employed in both research and clinical care to enhance our understanding of outcomes that matter to patients. This narrative review aims to describe PROM use in recent pediatric surgical research, identify and describe psychometrically robust PROMs, providing an overview of those derived from pediatric patient input, and make recommendations for future research.
Materials and Methods A search was conducted to identify articles published from 2021 to August 2023 describing the availability and/or use of at least one valid or reliable PROM in children with conditions including anorectal malformations, biliary atresia, congenital diaphragmatic hernia, duodenal atresia, esophageal atresia, abdominal wall defects, Hirschsprung's disease, sacrococcygeal teratoma, and short bowel syndrome. Articles were categorized based on their objectives in applying PROMs. Psychometrically robust PROMs were identified and described.
Results Out of the 345 articles identified, 49 met the inclusion criteria. Seventeen focused on esophageal atresia and 14 on Hirschsprung's disease. Twenty-nine PROMs were identified, with 12 deemed psychometrically robust. Seven psychometrically robust PROMs were developed using patient input in the primary item generation. Most PROMs were applied to advance understanding of conditions and/or treatment and fewer were developed or psychometrically evaluated. No PROMs were assessed for their impact or incorporated into an implementation study.
Conclusions This review reveals gaps in the application of PROMs in recent pediatric surgical research. Emphasis should be placed on the development and utilization of psychometrically robust PROMs, broadening the scope of covered diseases, conducting impact assessments, and evaluating implementation strategies.

Published: January 2024

Objective We aimed to determine whether exposure to severe maternal preeclampsia (PE) in very low birth weight (VLBW) infants is associated with hypertrophic cardiac changes and altered hemodynamics.
Study Design Case–control study of VLBW infants born at Los Angeles General Medical Center from May 2015 to August 2023, who had an echocardiogram within the first 7 days of life. Cases were infants exposed to maternal PE and controls were infants not exposed to maternal PE matched by birth weight (BW) 1:1. Laboratory, placental pathology results, hemodynamic data and clinical outcomes were collected and compared between cases and control infants.
Results A total of 43 cases matched by BW with control infants were studied. There were no significant anatomical cardiac changes by echocardiography between cases and control infants. Cases had significantly higher blood pressure within the first 72 hours of life and lower ejection fraction (EF), fractional shortening, and peak systolic flow velocity through their patent ductus arteriosus (PDA) within the first week of life. Cases were more likely to be smaller despite being born at a later gestational age (GA), as well as small for GA with placental weight less than 10th percentile compared to control infants.
Conclusion Our findings indicate that infants born to mothers with PE have higher systemic vascular resistance as evidenced by elevated blood pressure, and lower EF and shortening fraction and higher pulmonary vascular resistance as evidenced by lower peak flow velocity through the PDA. We did not observe hypertrophic cardiac changes in exposed infants. These findings should be considered in clinical decision-making during management of these infants.

Published: January 2024

Polymer infiltrated nanoporous gold is prepared by infiltrating polymer melts into a bicontinuous, nanoporous gold (NPG) scaffold. Polystyrene (PS) films with molecular weights (Mw) from 424 to 1133 kDa are infiltrated into a NPG scaffold (∼120 nm), with a pore radius (Rp) and pore volume fraction of 37.5 nm and 50%, respectively. The confinement ratios (Γ=RgRp) range from 0.47 to 0.77, suggesting that the polymers inside the pores are moderately confined. The time for PS to achieve 80% infiltration (τ80%) is determined using in situ spectroscopic ellipsometry at 150 °C. The kinetics of infiltration scales weaker with Mw, τ80%∝Mw1.30±0.20, than expected from bulk viscosity Mw3.4. Furthermore, the effective viscosity of the PS melt inside NPG, inferred from the Lucas–Washburn model, is reduced by more than one order of magnitude compared to the bulk. Molecular dynamics simulation results are in good agreement with experiments predicting scaling as Mw1.4. The reduced dependence of Mw and the enhanced kinetics of infiltration are attributed to a reduction in chain entanglement density during infiltration and a reduction in polymer–wall friction with increasing polymer molecular weight. Compared to the traditional approach involving adding discrete particles into the polymer matrix, these studies show that nanocomposites with higher loading can be readily prepared, and that kinetics of infiltration are faster due to polymer confinement inside pores. These films have potential as actuators when filled with stimuli-responsive polymers as well as polymer electrolyte and fuel cell membranes.

Published: January 2024

Due to the limitation of inherent ultra-high electron concentration, the electrical properties of In2O3 resemble those of conductors rather than semiconductors prior to special treatment. In this study, the effect of various annealing treatments on the microstructure, optical properties, and oxygen vacancies of the films and transistors is systematically investigated. Our finding reveals a progressive crystallization trend in the films with increasing annealing temperature. In addition, a higher annealing temperature is also associated with the reduction in the concentration of oxygen vacancies, as well as an elevation in both optical transmittance and optical bandgap. Furthermore, with the implementation of annealing process, the devices gradually transform from no pronounced gate control to exhibit with excellent gate control and electrical performances. The atomic layer deposited Hf-doped In2O3 thin film transistor annealed at 250 °C exhibits optimal electrical properties, with a field-effect mobility of 18.65 cm2 V−1 s−1, a subthreshold swing of 0.18 V/dec, and an Ion/Ioff ratio of 2.76 × 106. The results indicate that the impact of varying annealing temperatures can be attributed to the modulation of oxygen vacancies within the films. This work serves as a complementary study for the existing post-treatment of oxide films and provides a reliable reference for utilization of the annealing process in practical applications.

Authors: Wang Lan 
Published: January 2024

Summary
In the dynamic matrix of urban development, the conservation of heritage sites and the imperative of modernisation often find itself at a challenging nexus. This case study delves into the intricate interplay between urban heritage conservation and contemporary socio-economic demands, using the transformative narrative of Lau Pa Sat, Singapore, as a focal case. Drawing upon the dual paradigms of “use value” and “exchange value”, the research underscores the potential of heritage sites to both conserve cultural memory and catalyse modern economic revitalisation. Lau Pa Sat’s adaptive repurposing from a historical edifice to a dynamic hawker hub exemplifies a successful synthesis of architectural preservation and entrepreneurial initiative. Such an approach ensures the site’s functional sustainability while amplifying its cultural resonance. The research further highlights the significance of multi-stakeholder participation in rejuvenating urban memory through visual representation, communal spaces, and cultural paradigms. The findings underscore that, with strategic planning and community engagement, heritage sites can transcend historical confines, emerging as vibrant spaces that harmonise cultural conservation with contemporary relevance. This study provides invaluable insights for urban planners, policy makers, and heritage management professionals, advocating for a holistic approach that balances cultural stewardship with economic imperatives in urban heritage contexts.

The decay curves of luminescence from Eu2+ in β-SiAlON are effectively analyzed using the general-order kinetics formula
Authors: Suda Yoriko , Okuno Tsuyoshi , Takeda Takashi , Takahashi Kohsei , Hirosaki Naoto 
Published: January 2024

Abstract
Defects in phosphors affect not only luminescence intensity but also emission peak width, decay time, and afterglow. The green phosphor β-SiAlON:Eu2+ exhibits the green emission of Eu2+ at 520 nm and the blue emission of nitrogen vacancies at 460 nm in time-resolved fluorescence measurements. The decay time of the intrinsic Eu2+ transition is 0.7 μs, but afterglow is detected from 50 μs to 0.01 s. This afterglow decay curve is the same for the green emission of Eu2+ and the blue emission of nitrogen vacancies, suggesting that the defect levels of the nitrogen vacancies affect the Eu2+ transition. The afterglow decay curves were analyzed using the formula of the general-order kinetics,

Influence of light neutron-rich exotic nuclei in deciding abundance patterns relevant for explosive nucleosynthesis
Authors: Barman J , Sarkar S , Chatterjee R 
Published: January 2024

Abstract
Exotic neutron-rich nuclei play an important role in r-process nucleosynthesis. We study the effect of including proper nuclear structure to calculate neutron capture and photodisintegration rates, especially for 19C and 20N, under the aegis of post-form distorted wave Born approximation (FRDWBA). Considering a network of neutron-rich C–N–O isotopes, we show the effect on abundance calculations in a neutrino-driven wind environment of a core-collapse supernova at two critical temperatures T
9 = 3.4 and 0.62. The results are compared for nuclear physics inputs sourced from the FRDWBA, statistical estimates, and standard databases. At temperatures T
9 = 3.4, where alpha capture, or at T
9 = 0.62, where the neutron capture dominates, one can distinguish the effect of accounting for the exotic nature of the nuclei involved. Furthermore, we assess the impact of varying neutron capture and photodisintegration rates involving halo or bubble structures on the abundances within the network.

Remaining useful life prediction of bearings using a trend memory attention-based GRU network
Authors: Li Jingwei , Li Sai , Fan Yajun , Ding Zhixia , Yang Le 
Published: January 2024

Abstract
Remaining useful life (RUL) prediction of bearings holds significant importance in enhancing the reliability and durability of rotating machinery. Bearings undergo a gradual degradation process that unfolds over multiple stages. In this paper, a novel framework for forecasting the RUL of bearings is put forward, which includes the construction of a health indicator with a stage division algorithm (SDA) and the estimation of the health indicator using a new trend memory attention-based gated recurrent unit (TMAGRU). The SDA, based on the K-Means++ algorithm and angle recognition algorithm, is introduced to distinguish the degradation stage based on the health indicator. Inspired by the double exponential smoothing technique and attention mechanism, the proposed TMAGRU network effectively incorporates both the historical health information in the slow degradation stage and its trend. Experimental results conducted on IEEE PHM Challenge 2012 dataset and XJTU-SY dataset demonstrate the superior predictive performance of the proposed approach compared to several state-of-the-art predictive networks.
