Published: October 2024

AimsThe aim of this study was to evaluate the suitability of the tapered cone stem in total hip arthroplasty (THA) in patients with excessive femoral anteversion and after femoral osteotomy.MethodsWe included patients who underwent THA using Wagner Cone due to proximal femur anatomical abnormalities between August 2014 and January 2019 at a single institution. We investigated implant survival time using the endpoint of dislocation and revision, and compared the prevalence of prosthetic impingements between the Wagner Cone, a tapered cone stem, and the Taperloc, a tapered wedge stem, through simulation. We also collected Oxford Hip Score (OHS), visual analogue scale (VAS) satisfaction, and VAS pain by postal survey in August 2023 and explored variables associated with those scores.ResultsOf the 58 patients (62 hips), two (two hips) presented with dislocation or reoperation, and Kaplan-Meier analysis indicated a five-year survival rate of 96.7% (95% CI 92.4 to 100). Mean stem anteversion was 35.2° (SD 18.2°) for the Taperloc stem and 29.8° (SD 7.9°) for the Wagner Cone stem; mean reduction from Taperloc to Wagner Cone was 5.4° (SD 18.8°). Overall, 55 hips (52 patients) were simulated, and the prevalence of prosthetic impingement was lower for the Wagner Cone (5.5%, 3/55) compared with the Taperloc (20.0%, 11/55) stem, with an odds ratio of 0.20 (p = 0.038). Among the 33 respondents to the postal survey (36 hips), the mean scores were VAS pain 10.9, VAS satisfaction 86.9, and OHS 44.7. A multivariable analysis revealed that reduction of stem anteversion from Taperloc to Wagner Cone was more favourable for VAS pain (p = 0.029) and VAS satisfaction (p = 0.002).ConclusionThe mid-term survival rate for THA using the Wagner Cone stem was high, which may be supported by a reduction in prosthetic impingement. The reduction in excessive stem anteversion by using a tapered cone stem was associated with reduced pain and increased patient satisfaction.Cite this article: Bone Jt Open 2024;5(10):858–867.

Estudio comparativo con medición inicial y medición posterior a la implementación del Programa de Educación Emocional Pisotón. Muestra de 6.808 niños y niñas entre 3 y 7 años en 18 departamentos afectados por el conflicto armado colombiano. El instrumento fue Fábulas de Düss, analizándose las respuestas a partir de la clasificación de Bell (1992). Se realizaron pruebas de comparación de proporciones mediante Chi cuadrado y prueba Z, estudiando diferencias significativas entre grupos. En las fábulas 1 a 7 y 9 siempre se cumple que la proporción en el grupo “significativo" y “resistencia” es menor que la proporción en el grupo “normal” después de la implementación del Programa, lo cual indica un aumento estadísticamente significativo en el número de participantes ubicados en la categoría Normal.
El papel del ocio en la intervención psicosocial con víctimas de la trata: una revisión sistemática
Authors: Chacón Alexandra , Codina Nuria 
Published: October 2024

Introducción: La trata de personas con finalidad de explotación sexual es una práctica esclavista que acarrea un excelso grado de violencia; requiriendo que la intervención psicosocial preste recursos centrados en la recuperación psicológica de las víctimas. En este sentido, el ocio es un recurso terapéutico que permite afrontar los estresores traumáticos y abordar el desarraigo y los estigmas que sufren las víctimas sexuales; alejándose así de las extendidas intervenciones asistencialistas y paliativas. Sin embargo, parecen poco generalizadas las intervenciones que incorporan el ocio terapéutico. Objetivo: Realizar una revisión sistemática de los trabajos publicados respecto a intervenciones con mujeres víctimas de explotación sexual que contemplan el ocio terapéutico. Metodología: Se revisan las bases de datos Psicodoc, PsycInfo y Sociological Abstracts, utilizando las palabras claves, en castellano, víctimas sexuales o prostitutas, intervención, ocio y en inglés, sexual victim o prostitute, intervention, leisure.Resultados: Se identificaron un total de 725 publicaciones mayoritariamente de orientación sociológica. Después de los cribados quedaron 19 trabajos, los cuales también fueron descartados tras un análisis del contenido de los mismos. Discusión: Los resultados reflejan como la intervención psicosocial orientada a recuperar en su integridad a las víctimas de la violencia sexual no está documentada ni registrada en bases de datos científicas. Conclusiones: Habiendo evidenciado el significativo grado de desatención a la recuperación integral de las víctimas de la trata, se reclama la necesidad de difundir y facilitar experiencias en la gestión del ocio terapéutico como herramienta para intervenir en este colectivo.

Published: October 2024

En este estudio, hemos querido analizar la relación entre la percepción de maltrato y la experimentación de las diferentes formas de abuso en las relaciones de noviazgo en parejas jóvenes. Igualmente, y según sea dicha percepción, evaluar la influencia que las actitudes ejercen en la experimentación de maltrato dentro de las relaciones de pareja. Para ello, han participado un total de 450 estudiantes de educación Secundaria y Universitarios, de ambos sexos y edades comprendas entre los 18 y 28 años, siendo el 30.2% varones, y el 69.8% mujeres. Los instrumentos de evaluación utilizados han sido el Cuestionario de Violencia de Novios Reducido, enfocado al estudio de la violencia dentro de las relaciones de noviazgo, y la Escala de Actitud de Rol de Género, que se encuentra destinada a la evaluación de la manifestación de actitudes sexistas o igualitarias. Los resultados muestran que la autopercepcion de maltrato se relaciona significativamente con la experiencia de victimización, al mismo tiempo que las actitudes de carácter sexista favorecerán la probabilidad de experimentar las diferentes formas de maltrato en las relaciones de pareja joven

Authors: Gonçalves Oliveira Lila , Sala Escarrabill Roser 
Published: October 2024

La resiliencia organizacional sanitaria es fundamental para enfrentar las crisis repentinas o crónicas, mediante la capacidad de planificación y adaptación. El presente estudio exploratorio tuvo como objetivo describir la resiliencia organizacional percibida por 325 trabajadores sanitarios de Barcelona antes de la pandemia por COVID-19. Los participantes percibieron a sus respectivos hospitales como organizaciones con una resiliencia media, con mayor capacidad de planificación ante las crisis que capacidad de adaptación una vez ocurridas. Las principales fortalezas de resiliencia fueron la creencia de que los planes de emergencia se deben practicar y la importancia del trabajo de equipo en respuesta a las crisis. Como debilidades se identificaron la falta de conciencia sobre las prioridades para la recuperación y el no alentar la innovación en la resolución de los problemas. Se encontraron diferencias significativas por grupos sociodemográficos, relevantes para el diseño de planes de intervención. Los hallazgos cobran mayor sentido tras la ocurrencia de la pandemia por COVID-19, puesto que representan una línea de base única para futuros estudios.

Published: October 2024

3D single-molecule imaging reveals nanoscale structures in cell volumes but is limited by the need for spectrally distinct fluorophores. We address this limitation with vortex light field microscopy (VLFM), a 3D spectral single-molecule localization technique with 25 nm spatial and 3 nm spectral precision over a 4 µm depth of field. By modifying our previous single-molecule light field microscope with an azimuthally oriented prism array, we generated spectral disparity orthogonal to axial disparity, enabling simultaneous spatial and spectral localization on a single detector. We demonstrate VLFM with four-color 3D single-particle tracking and two-color 3D dSTORM imaging in fixed cells, successfully identifying dyes with spectral peaks just 15 nm apart. This shows VLFM’s potential for enhancing spatial biology workflows requiring highly multiplexed imaging.

Authors: Müller Lars , Debus Eike Sebastian , Karsai Syrus , Alm Jens 
Published: October 2024

Background
Recurrences after varicose vein treatment occur frequently and represent a significant health and economic problem. In contrast to primary treatments of superficial truncal venous insufficiency, their management is often more difficult. Here we assessed the technical feasibility and early results of endovenous laser ablation (EVLA) for recurrences with stumps or subfascial meandering varices after small saphenous vein (SSV) surgery.

Methods
This single-center retrospective study included 45 consecutive EVLA procedures from July 2019 to December 2021 in 40 patients (19 male, 21 female, mean age 62.8 ± 12.7 years). Patients had clinically relevant recurrent varicose veins after SSV surgery, with clinical, etiologic, anatomic and pathophysiologic (CEAP) classification stage of C2S or higher. We categorized the recurrences morphologically according to duplex sonographic criteria. Ablations were done with a 1470 nanometers laser and dual ring radial fibers and aimed at thermal closure as proximal as possible to the upper inflow. Analyses were performed by descriptive statistics and the Kaplan-Meier method. The primary outcome analyzed was the technical success, defined by thermal occlusion not requiring re-intervention during the observation period. The secondary outcome was the occurrence of postoperative complications.

Results
A complex morphology with residual stumps or tortuous venous connections to the popliteal vein was present in 35 cases (77.8%). Immediate technical success at the first postoperative visit after a median of 11 days (interquartile range 8–13 days) was 97.8%. During the follow-up period (median 77 days, interquartile range 13–256 days), 6 limbs (13.3%) required redo EVLA due to symptomatic persistent or newly presenting reflux. The median freedom from re-recurrence was 791 days. Otherwise, no medical or surgical complications requiring specific treatment were observed, particularly no endothermal heat-induced thrombosis (EHIT) or other thrombotic complications, and no nerve damage.

Conclusion
According to our pilot data, EVLA is technically feasible for complex popliteal variceal recurrence, although the success rate appears substantially lower than for primary treatment of truncal venous insufficiency.
Does reducing smartphone use impact physical activity?
Authors: Le Steunf Annaëlle , Page Ewen , Guillodo Yannick , Saraux Alain 
Published: October 2024

Introduction
A sedentary lifestyle and low levels of physical activity among the population are major public health challenges due to numerous associated health risks. These behaviors are influenced by a number of environmental and cultural factors, such as screen addiction.

Objective
To study the impact of reducing smartphone use by one hour per day for one week on physical activity.

Method
We conducted a descriptive epidemiological study that included 490 individuals. Participants were recruited by means of a media campaign called “Let’s put down our smartphones challenge”, which was conducted in Brest, France. The questionnaires were widely publicized, and candidates from all over France were able to participate. Data reflecting physical activity were collected before and after the challenge, one week apart, through an online questionnaire.

Results
Among the 490 participants, 126 (25.7%) succeeded in the challenge and reduced the time spent on their smartphones by more than 60 minutes. Among those 126 participants, 112 individuals (89%) increased their physical activity. On average, participants who succeeded in the challenge reduced their smartphone use by 110.57 minutes (±53.66) (p< 0.001) and increased their number of steps by 841 (±14710) (p = 0.02). The proportion of patient reaching an increase of both 500 and 100 daily steps was statistically significant in the group reaching a reduction of smartphone use of 60 minutes versus the remainder (p = 0.016 and 0.018, respectively), but not for a cut off at 1000.

Conclusion
A reduction in the time spent using smartphones results in an increase in the average number of daily steps. Limiting the leisure time spent on screens is a potential strategy for addressing physical inactivity and a sedentary lifestyle.

Purpose
This study investigated the differential gene expression of BMPs in chick retinal pigment epithelium (RPE) during recovery from short term exposure to optical defocus and form-deprivation (FD) treatments.

Methods
14-day old White-Leghorn chicks wore either monocular +10 or -10 D lenses, or diffusers for 2 or 48 h, after which eyes were allowed unobstructed vision for up to 96 h. Over this recovery period, refractive errors and choroidal thickness (ChT) were tracked using retinoscopy and high-frequency A-scan ultrasonography. Real-time PCR was used to examine the expression of BMP2, 4, and 7 genes in RPE samples collected 0, 15 min, 2, 24, 48, and 96 h after the termination of treatments. Expression levels in treated eyes and their contralateral control eyes were compared.

Results
After the termination of the lens and diffuser treatments, eyes gradually recovered from induced shifts in refractive error. With all three treatments, ChT changes reached statistical significance after 48 h of treatment, be it thinning with the -10 D lens and diffuser treatments (-0.06 ± 0.03mm, p < 0.05; -0.11 ± 0.04 mm, p < 0.05, resp.), or thickening with the +10 D lens (0.31 ± 0.04 mm, p < 0.001). BMP2 gene expression was rapidly upregulated in eyes wearing the +10 D lens, being statistical significance after 2 h, as well as 48 h of treatment. With the 2 h treatment, the latter gene expression pattern persisted for 15 min into the recovery period, before decreasing to the same level as that of contralateral control eyes, with a short-lived rebound, i.e., upregulation, 24 h into the recovery period. With the longer, 48 h treatment, BMP2 gene expression decreased more gradually, from 739 ± 121% at the end of the treatment period, to 72 ± 14% after 48 h of recovery. Two and 48 h of both -10 D and FD treatments resulted in BMP2 gene expression downregulation, with the time taken for gene expression levels to fully recover varying with the duration of initial treatments. In both cases, BMP2 gene expression downregulation persisted for 15 min into the recovery period, but reversed to upregulation by 2 h. Similar gene expression patterns were also observed for BMP4, although the changes were smaller.

Conclusions
The observed changes in BMP gene expression in chick RPE imply dynamic, albeit complex regulation, with the duration of exposure and recovery being critical variables for all three types of visual manipulations. This study provides further evidence for a role of the RPE as an important signal relay linking the retina to the choroid and sclera in eye growth regulation.

Abstract

Significance
Studying the flow of ternary nanofluids [Ag, Cu, MoS2] holds significant importance in both science and engineering. Ternary nanofluids are vital in advancing thermal management systems, heat exchangers, aerospace, and materials processing applications.

Purpose
This study investigates the ternary hybrid Carreau nanofluid numerically for thermal proficiency in the inclined magnetized environment. In this study, three distinct nanoparticles of [Ag, Cu, MoS2] and base fluid water over the wedge are used. The velocity of nanofluids is judged under the influence of an inclined magnetic field, and the thermal performance is scrutinized by incorporating the thermal radiation effect.

Methodology
The physical problem generates partial differential equations, which are transformed into ordinary differential equations (ODEs) through similarity variables. These ODEs are linearized into a system of ODEs and then passed under the bvp4c Matlab program to get the solution. This solution is again trained by an artificial neural network, and further results are obtained with both schemes and compared.

Findings
The most rapid heat transport analysis is found for ternary hybrid nanofluids compared to bi-hybrid nanofluids. The thermal radiation parameters and the magnetic environment augment the rate of heat transport.
A closed-form solution of BER for a convolutional coded non-Hermitian OFDM FSO system with polarization diversity
Authors: Quaium Adnan , Barua Bobby , Islam M. Shariful , Morshed Monjur 
Published: October 2024

Abstract
In this article, we investigate the performance of convolutional coding against the fading associated due to atmospheric turbulence as well as the polarization-induced crosstalk in free-space optical (FSO) communication system. The performance of FSO system strongly depends on atmospheric turbulence. Orthogonal frequency division modulation (OFDM) is one kind of solution for frequency selective fading channel. The OFDM modulated output signal is complex, which is not possible to transmit through FSO channel. To overcome this constraint, we consider non-Hermitian approach by adding polarization diversity. However, polarization add crosstalk to the system, which deteriorates the system bit error rate (BER) performance. All the analytical simulation results are presents graphically by using MATLAB software. All the provided results are in terms of system’s BER by varying the number of OFDM subcarrier, local oscillator power, link distance, and mean misalignment angle. Our earlier published article where we used space frequency block code (SFBC) and reported that almost 7.5 dB coding gain possible. In this proposed system model, we considered convolutional code instead of SFBC and found a significant amount almost 10 dB coding gain at a BER of 10−12 when all the system’s parameter remains unchanged. Finally, we developed the closed-form expression of system’s average BER.
Development of a Comprehensive Regulatory Model for Medical Devices

Published: October 2024

Abstract

Background: The development of a comprehensive regulatory model for medical devices is essential to ensure the safety, efficacy, and quality of medical devices throughout their lifecycle, from design and development to post-market surveillance. This paper outlines a robust framework for such a regulatory model, detailing key components and processes necessary for effective regulation.

Methods: The data and literature were collected from various databases including Springer, Science Direct, Taylor and Francis, Wiley, Bentham Science, and websites of different regulatory agencies. The collected data were utilized in the research work to formulate the new regulatory model.

Results: Different guidelines represent acceptable regulatory practices for all medical items. There are four risk classification levels of the medical devices (class I–IV, based on the risk level). For every country, the regulatory requirements are different. Global regulations for medical device approval are essential to guaranteeing their quality, safety, efficacy, and performance before they can be put on the market to safeguard, prevent, enhance, and maintain public health. Different classes have different regulatory steps for approval of the devices, which varies from region to region. The World Health Organization’s Department of Essential Health Technologies’ Diagnostic Imaging and Medical Devices team has developed and implemented the Baseline Country Survey on Medical Devices. The proposed model includes the establishment of a clear legislative and regulatory framework, featuring a risk-based classification system aligned with international standards. It emphasizes rigorous pre-market requirements, including design controls, clinical evaluation, quality management systems, and technical documentation. Market authorization processes are described, highlighting pathways such as Premarket Notification (510(k)), Premarket Approval (PMA), and De Novo Classification, supported by thorough scientific review and expert advisory panels. The present study is all about the global requirements of the regulation of the medical devices and it was concluded that overall, a global comprehensive regulatory model for medical devices aims to strike a balance between ensuring patient safety, facilitating innovation, and enabling timely access to life-saving medical technologies around the world.

Conclusion: The model advocates for international harmonization and collaboration, promoting regulatory convergence and the adoption of global standards. It also supports innovation through accelerated approval pathways and regulatory sandboxes, alongside continuous improvement driven by regulatory science research and stakeholder engagement. By integrating these elements, the comprehensive regulatory model aims to protect public health while fostering medical device innovation and ensuring global regulatory compatibility.
Pensar lo socioterritorial - Editorial
Authors: Farres Delgado Yasser 
Published: October 2024

El término “socioterritorial” se ha convertido durante las últimas décadas en una categoría de análisis cada vez más recurrida tanto en el estudio de problemáticas sociales como de problemáticas territoriales. En el caso de América Latina y el Caribe, ello se evidencia el incremento del número de artículos publicados en revistas científicas regionales recogidas en Redalyc y Scielo, como muestra la tabla. Es cierto que durante la primera mitad de la presente década se ha visto una tendencia contraria; sin embargo, no parece casual que coincida con el período de pandemia y postpandemia de COVID 19 y el aumento exponencial de publicaciones sobre este otro tema. De hecho, mientras que los mayores registros acerca de lo socioterritorial en Redalyc y Scielo fueron 246 artículos en 2016 y 45 artículos en 2022, respectivamente, solo en Scielo el número de publicaciones sobre COVID pasó de 72 en el año 2019, a 4863 en el 2020, y 5768 en 2021, seguidos de una lógica disminución tras el fin del forzado encierro mundial (4877 artículos en 2022, 3166 en 2023 y 403 en lo transcurrido de 2024).
