Introducción: La empatía es uno de los componentes de la estructura de la humanización en la atención de los pacientes. Los médicos especialistas deben tener altos niveles de empatía. Objetivo. El objetivo del presente trabajo es describir los niveles de empatía en médicos que trabajan en un hospital de alta complejidad y explorar diferencias entre las especialidades estudiadas. Métodos: Muestra por conveniencia de 237 médicos que representa el 53,55 % del total poblacional (N=443). La empatía fue medida mediante la Escala de Empatía para Profesionales de la Salud. Se realizó análisis factorial confirmatorio y análisis multigrupo para examinar la invarianza del modelo entre los sexos y análisis de confiabilidad (α de Cronbach, coeficiente de correlación intraclase y ω de McDonald). Resultados: La especialidad de pediatría tuvo los niveles más altos en la empatía general y en las dimensiones Cuidado con compasión y “Caminando en los zapatos del paciente”, no así en la dimensión Toma de perspectiva donde presenta niveles semejantes a las especialidades de anestesiología, medicina crítica y terapia intensiva, y ginecología. Conclusión: Los valores de la empatía y los valores en las subescalas Cuidado con compasión y “Caminando en los zapatos del paciente” fueron (en valores absolutos, pero no estadísticos) mayores en la especialidad de Pediatría. En la subescala Toma de perspectiva, las especialidades de Pediatría, Anestesiología, Cirugía y Clínica se observaron puntuaciones prácticamente iguales. Se requieren otros estudios que permita arribar a una explicación que permita entender por qué algunas especialidades tienen valores de empatía mayores que otras.

AimsTo investigate the impact of consecutive perioperative care transitions on in-hospital recovery of patients who had primary total knee arthroplasty (TKA) over an 11-year period.MethodsThis observational cohort study used electronic health record data from all patients undergoing preoperative screening for primary TKA at a Northern Netherlands hospital between 2009 and 2020. In this timeframe, three perioperative care transitions were divided into four periods: Baseline care (Joint Care, n = 171; May 2009 to August 2010), Function-tailored (n = 404; September 2010 to October 2013), Fast-track (n = 721; November 2013 to May 2018), and Prehabilitation (n = 601; June 2018 to December 2020). In-hospital recovery was measured using inpatient recovery of activities (IROA), length of stay (LOS), and discharge to preoperative living situation (PLS). Multivariable regression models were used to analyze the impact of each perioperative care transition on in-hospital recovery.ResultsThe four periods analyzed involved 1,853 patients (65.9% female (1,221/1,853); mean age 70.1 years (SD 9.0)). IROA improved significantly with each transition: Function-tailored (0.9 days; p < 0.001 (95% confidence interval (CI) -0.32 to -0.15)), Fast-track (0.6 days; p < 0.001 (95% CI -0.25 to -0.16)), and Prehabilitation (0.4 days; p < 0.001 (95% CI -0.18 to -0.10)). LOS decreased significantly in Function-tailored (1.1 days; p = 0.001 (95% CI -0.30 to -0.06)), Fast-track (0.6 days; p < 0.001 (95% CI -0.21 to -0.05)), and Prehabilitation (0.6 days; p < 0.001 (95%CI -0.27 to -0.11)). Discharge to PLS increased in Function-tailored (77%), Fast-track (91.6%), and Prehabilitation (92.6%). Post-hoc analysis indicated a significant increase after the transition to the Fast-track period (p < 0.001 (95% CI 3.19 to 8.00)).ConclusionThis study highlights the positive impact of different perioperative care procedures on in-hospital recovery of patients undergoing primary TKA. Assessing functional recovery, LOS, and discharge towards PLS consistently, provides hospitals with valuable insights into postoperative recovery. This can potentially aid planning and identifying areas for targeted improvements to optimize patient outcomes.Cite this article: Bone Joint J 2024;106-B(6):573–581.

Published: June 2024

AimsThe aim of this study was to compare the pattern of initial fixation and changes in periprosthetic bone mineral density (BMD) between patients who underwent total hip arthroplasty (THA) using a traditional fully hydroxyapatite (HA)-coated stem (T-HA group) and those with a newly introduced fully HA-coated stem (N-HA group).MethodsThe study included 36 patients with T-HA stems and 30 with N-HA stems. Dual-energy X-ray absorptiometry was used to measure the change in periprosthetic BMD, one and two years postoperatively. The 3D contact between the stem and femoral cortical bone was evaluated using a density-mapping system, and clinical assessment, including patient-reported outcome measurements, was recorded.ResultsThere were significantly larger contact areas in Gruen zones 3, 5, and 6 in the N-HA group than in the T-HA group. At two years postoperatively, there was a significant decrease in BMD around the proximal-medial femur (zone 6) in the N-HA group and a significant increase in the T-HA group. BMD changes in both groups correlated with BMI or preoperative lumbar BMD rather than with the extent of contact with the femoral cortical bone.ConclusionThe N-HA-coated stem showed a significantly larger contact area, indicating a distal fixation pattern, compared with the traditional fully HA-coated stem. The T-HA-coated stem showed better preservation of periprosthetic BMD, two years postoperatively. Surgeons should consider these patterns of fixation and differences in BMD when selecting fully HA-coated stems for THA, to improve the long-term outcomes.Cite this article: Bone Joint J 2024;106-B(6):548–554.

Published: June 2024

AimsThis study compares the re-revision rate and mortality following septic and aseptic revision hip arthroplasty (rTHA) in registry data, and compares the outcomes to previously reported data.MethodsThis is an observational cohort study using data from the German Arthroplasty Registry (EPRD). A total of 17,842 rTHAs were included, and the rates and cumulative incidence of hip re-revision and mortality following septic and aseptic rTHA were analyzed with seven-year follow-up. The Kaplan-Meier estimates were used to determine the re-revision rate and cumulative probability of mortality following rTHA.ResultsThe re-revision rate within one year after septic rTHA was 30%, and after seven years was 34%. The cumulative mortality within the first year after septic rTHA was 14%, and within seven years was 40%. After multiple previous hip revisions, the re-revision rate rose to over 40% in septic rTHA. The first six months were identified as the most critical period for the re-revision for septic rTHA.ConclusionThe risk re-revision and reinfection after septic rTHA was almost four times higher, as recorded in the ERPD, when compared to previous meta-analysis. We conclude that it is currently not possible to assume the data from single studies and meta-analysis reflects the outcomes in the ‘real world’. Data presented in meta-analyses and from specialist single-centre studies do not reflect the generality of outcomes as recorded in the ERPD. The highest re-revision rates and mortality are seen in the first six months postoperatively. The optimization of perioperative care through the development of a network of high-volume specialist hospitals is likely to lead to improved outcomes for patients undergoing rTHA, especially if associated with infection.Cite this article: Bone Joint J 2024;106-B(6):565–572.

Twenty-first-century skills should be integrated into higher education to prepare students for complex working-life challenges. Artificial intelligence (AI)-powered tools have the potential to optimise skill development among higher education students. Therefore, it is important to conceptualise relevant affordances of AI systems for 21st-century skills development in higher education. This study aimed to present an overview of journal articles published in the Web of Science database that specifically addressed the affordances of AI-based tools for 21st-century skills development. Four distinct categories of AI-based tools (intelligent tutoring systems, chatbots, AI-powered dashboards and automated grading systems) were identified as capable of promoting six main 21st-century skills (collaboration, communication, creativity, critical thinking, information and communication technology and problem-solving). The review revealed that the utilisation of AI-based tools might contribute to the simultaneous development of multiple 21st-century skills (e.g., collaboration and critical thinking). The results showed that adaptive feedback from AI plays a significant role as a facilitator in the development of 21st-century skills. Furthermore, the utilisation of diverse functional AI affordances (e.g., prediction and profiling) might contribute to the development of various skills. AI-based technologies appeared to target the 21st-century skills of problem-solving and its subskills the most.

Implications for practice or policy:

More functional affordances of AI (e.g., prediction and profiling) should be employed in AI-based tools. This could support higher education students’ 21st-century skills.
AI-based tools (e.g., chatbots and intelligent tutors) interact with end users through their data. AI systems have the potential to promote 21st-century skills by using students’ multimodal data.
AI technologies should be more integrated into the social sciences and humanities in the higher education context to support students’ 21st-century skills.

Published: June 2024

Abstract
As a cultural carrier of historical inheritance, paper has high cultural, historical and scientific research value. But with the passage of time and the change of the environment, many paper are aging and damaged. In order to protect the paper, CMC-β-CD composite material for paper protection was synthesized by carboxymethyl cellulose as substrate, epichlorohydrin (ECH) as crosslinking agent, sodium hydroxide (NaOH) as catalyst and solvent, and water as medium, β-cyclodextrin as grafter. Through single factor experiment, the synthetic condition was obtained. The structure of the synthesized materials was characterized by infrared spectroscopy; CMC-β-CD was applied to paper reinforcement. The effects of solution concentration on the tensile strength, tearing degree, folding times, whiteness and gloss of paper were tested, and the suitable conditions for coating paper were found. The results show that the mass concentration of 2 % CMC-β-CD is coated on paper, its mechanical properties are greatly improved, the gloss is slightly increased, and the whiteness is basically unchanged, which is in line with the principle of “repairing the old as the old”.
Gold nanoparticles capped with α-cyclodextrin for dual colorimetric sensing of Fe3+ and Cr3+ in tap water

Published: June 2024

Abstract
A rapid colorimetric assay for the dual detection of Fe3+ and Cr3+ using gold nanoparticles (AuNPs) capped with α-cyclodextrin was developed. The synthesized AuNPs produced a red wine color with a particle size of 8.60 ± 1.55 nm and were stable for 9 months. Detection of Fe3+ and Cr3+ changed the color of the AuNPs solution to bluish purple with a detection time of <1 and 10 min, respectively. Reaction of the AuNPs with Fe3+ and Cr3+ also increased the particle size of the AuNPs to 16.18 ± 2.28 nm and 17.33 ± 1.71 nm, respectively. Characterization of the AuNPs using Fourier-transform infrared spectroscopy and X-ray diffraction showed that the presence of Fe3+ would damage the structure of the AuNPs, whereas Cr3+ would not. This colorimetric sensor is sensitive toward Fe3+ and Cr3+ with limits of detection of 265.92 and 430.80 μg/L, respectively. The dual ion sensing ability of the AuNPs was also assessed by individually detecting Fe3+ and Cr3+ in tap water samples in South Tangerang, Banten, Indonesia.

Abstract
Due to the uncertainty of trauma or infection, customized bone substitutes are often required in clinic. Meanwhile, excessive use of antibiotics may lead to drug resistance. Therefore, the design of anti-infection bone tissue engineering scaffold is of very important. In this study, porous titanium alloy bone tissue engineering scaffolds were designed and fabricated by 3D printing. TiO2 nanotubes were further constructed on the scaffolds through electrochemical anodic oxidation, achieving the drug loading and anti-infection functions. The micron-level bionic pores were fabricated by the 3D printing process, and the secondary nanoscale-level nanotubes were achieved through the anodic oxidation process. Thereafter, the micro–nano structured porous bone tissue engineering scaffolds are presented. This structure features that the drug release rate can be regulated by loading the anti-infection drug minocycline and coating them with poly(lactic-co-glycolic acid) (PLGA) in the nanotubes. According to the results, the micro–nano composite porous scaffold showed uniform and controllable micro–nano pores, it may load anti-infection drugs and shown anti-infection ability. In addition, the PLGA coating may delay the drug release and maintain a sustained anti-infection function for the scaffold in a week. This study provides new ideas for designing antibacterial bone tissue engineering scaffold.
Spot Prices and Forward Premia on the MISO Exchange
Authors: Jones Kevin 
Published: June 2024

This paper explores information contained in the basis for wholesale electricity on the Midcontinent Independent System Operator (MISO) electricity exchange. Utilizing Fama and French’s (1987) approach, the basis is found to have predictive power on changes in real-time (spot) prices but provides only limited evidence of a time-varying forward premium. This result contradicts Huisman and Kilic’s (2012) theory that the basis in an electricity market which relies primarily on storable forms of power for electricity production (such as MISO) should contain information on both changes in spot prices and provide evidence of a time-varying forward premium.
Geomorphic Imprints of Active Tectonics of the Bikaner-Nagaur Petroliferous Rift Basin and its Surroundings (Western Rajasthan, India)

Abstract
Geology of sedimentary rift-basins require strong geomorphic input for a proper interpretation of active tectonics. Rift-related sedimentation took place in western Rajasthan of the Indian shield, which includes the Bikaner-Nagaur basin (BNB) and a few other adjacent basins. The sedimentation history of the BNB includes Proterozoic, Cambrian, Permo-Carboniferous and from Paleocene to the Recent. This study analyses river profiles with the best-fit curve (R2) model for the BNB and the surrounding regions. The research shows that the watershed 3 within the study area is most active tectonically, through which multiple faults and lineaments pass. Hypsometric Curves (HCs) of watersheds 1, 2 and 3 indicate that these watersheds are tectonically active. This inference is based on the concave profiles of HCs at the head, and convex profiles of HCs at the body and toe sections. Clustering of sixty segments (S) of the considered rivers based on linear-scale morphometric parameters, e.g., sinuosity index (SI), stream length gradient index (SL) and concavity (θ) enabled segment-wise comparison of river profiles with similar values. These segments were compared pair-wise, and Euclidean-based dissimilarity (dR) values were calculated between each such pair. The findings too imply that tectonic activeness exists in parts of watersheds 1, 2 and 3. The channel flow lines are controlled by faults/lineaments as per the micro-scale examination of the drainage network and faults/ lineaments analysis. Under structural control, nine major geomorphic units emerged with distinct erosional surfaces, denudational hillocks, dissected hills and inselbergs. Detailed geomorphic map with micro-scale studies revealed a slope retreat process that resulted in landforms viz., pediment, pediment slope and active flood plains.
First Report of Tuff in Neoproterozoic Bhima Basin: Field Evidence, Petrography and Geochemical Studies
Authors: Chakraborty Swarnava , Mahajan Manjusha , Sambre Vaishnavi , Sen Bibhas 
Published: June 2024

Abstract
We report here the presence of tuffs from the Neoproterozoic Bhima basin unreported hitherto. These are exposed near Hotpet, Hulkal, Kanchankavi, and Ukinal area along two different stratigraphic horizons (1) within carbonates of Shahabad Formation and (2) above shale of Hulkal Formation. Tuffs are of two types: 1. Ash fall tuff and 2. Lapilli tuff, occurring as beds, matrix of a conglomeratic unit and patchy discontinuous layers. Physically ash fall tuff is thinly bedded (2-6 cm) and light-weight, lapilli tuff is hard, compact and individual beds are not discernible in the field. Presence of petrological features like bipyramidal quartz, fiamme structures, embayed quartz grains, blue CL colours of quartz grains, volcanic layering and banding, altered glass, and stretched and elongated volcanic glasses, are clear indications of its volcanic affinity. The tuff is anomalously high in silica content ranging from 71.4-91.2wt% and have low alumina value ranging from 0.75-4.11 wt % compared with that of the normal felsic tuffs, rhyolites and high silica rhyolites. REE in the tuffs can be grouped into two types, 1. Ash fall tuff with enriched LREE and fractionated HREE, 2. Lapilli tuff with flat LREE and HREE pattern. Tuff shows high Hf, overall enrichment of large ion lithophile elements (LILE Rb, Th, K and Pb) and depletion in HFSEs (Nb, Ta, Ti, P). The tuff is probably generated from continental crust source and the depositions are episodic and have more than one eruptive pulses of volcanic activity.

Abstract
Kaolin is commonly used in many industries. This study was carried out to characterise selected kaolin deposits in the Abeokuta area of southwestern Nigeria and evaluate possible industrial applications. The mineralogy and geochemical composition were determined and used to evaluate the industrial application. Mineralogically, the samples are composed of kaolinite, quartz, mica, anatase, and minor hematite, k-feldspar, calcite, plagioclase and clino-pyroxene. The clays are mostly composed of hexagonal euhedral to subhedral plates of disordered kaolin. Geochemical characterisation revealed high SiO2 values, high SiO2/Al2O3 and Al2O3/TiO2 values which denotes high quartz concentration and sourcing from felsic igneous source respectively. Discriminant plots also revealed the kaolin are of intermediate to felsic ancestry while Ni/Co values revealed they were formed in anoxic environment. Comparison of the elemental concentration of industrial standards revealed the kaolin will be best suited for ceramics and refractory purposes though some of the clays may need upgrading by removal of excess Fe2O3 and TiO2 as well as addition of fluxing materials to improve its suitability for certain applications.
High-resolution Oxygen and Carbon Isotopic Records of a Modern and a Fossil Coral from the Lakshadweep Archipelago

Published: June 2024

ABSTRACT
We report here δ18O and δ13C records of a modern Porites and a fossil Favia coral from the Lakshadweep Island to decipher seasonal changes in seawater characteristics. The modern coral was obtained by underwater drilling of a live Porites colony of Kavaratti Island, whereas fossil Favia coral was collected from a nearby location of the same island. Our interpretation is mainly based on high-precision isotopic measurements of 378 samples. The skeleton δ18O values of Porites coral, representing a period of 25 years (between 1984 and 2008 AD), vary between – 5.1‰ and – 4.37‰ vs VPDB, whereas δ18O values of a &gt;400 yrs old fossil Favia coral exhibit significantly greater δ18O values, ranging from – 4.75 to – 3.39‰ vs VPDB. A plot of δ18O time series of modern Porites coral with the available sea surface temperature (SST) record of the study area exhibits an inverse relationship between coral δ18O and regional SST changes, suggesting temperature as the dominant factor for controlling δ18O in seasonal bands of corals. Seasonal variations in δ13C values in both the scleractinian corals were probably influenced mainly by variations in δ13C of dissolved inorganic carbon (DIC). However, carbon isotopic records also indicate the effects of biological (metabolic) processes on their δ13C. The greater seasonal amplitude recorded in δ18O and δ13C values of Favia coral than in Porites coral implies a marked difference in their metabolic processes.
