Abstract. The Particle Size Magnifier is widely used for measuring nano-sized particles. Here we calibrated the newly developed Particle Size Magnifier version 2.0 (PSM 2.0). We used 1–10 nm particles with different compositions, including metal particles, organic particles generated in the laboratory, and atmospheric particles collected in Helsinki and Hyytiälä. A noticeable difference among the calibration curves was observed. Atmospheric particles from Hyytiälä required higher diethylene glycol (DEG) supersaturation to be activated compared to metal particles (standard calibration particles) and other types of particles. This suggests that chemical composition differences introduce measurement uncertainties and highlights the importance of in situ calibration. The size resolution of PSM 2.0 was characterized using metal particles. The maximum size resolution was observed at 2–3 nm. PSM 2.0 was then operated in Hyytiälä for ambient particle measurements in parallel with a Half Mini differential mobility particle sizer (DMPS). During new particle formation (NPF) events, comparable total particle concentrations were observed between the Half Mini DMPS and PSM 2.0 based on Hyytiälä atmospheric particle calibration. Meanwhile, applying the calibration with metal particles to atmospheric measurements caused an overestimation of 3–10 nm particles. In terms of the particle size distributions, similar patterns were observed between the DMPS and PSM when using the calibration of Hyytiälä atmospheric particles. In summary, PSM 2.0 is a powerful instrument for measuring sub-10 nm particles and can achieve more precise particle size distribution measurements with proper calibration.

Published: January 2025

Abstract. This study presents the development and performance evaluation of an ozone differential absorption lidar system. The system could effectively obtain vertical profiles of lower-tropospheric ozone in an altitude range of 0.3 to 4 km with high spatiotemporal resolutions. The system emits three laser beams at wavelengths of 276, 287 and 299 nm by using the stimulated Raman effect of carbon dioxide (CO2). A 250 mm telescope and a grating spectrometer are used to collect and separate the backscattering signals at the three wavelengths. Considering the influences of aerosol interference and statistical error, a wavelength pair of 276–287 nm is used for the altitude below 600 m and a wavelength pair of 287–299 nm is used for the altitude above 600 m to invert ozone concentration. We also evaluated the errors caused by the uncertainty of the wavelength index. The developed ozone lidar was deployed in a field campaign that was conducted to measure the vertical profiles of ozone using a tethered balloon platform. The lidar observations agree very well with those of the tethered balloon platform.
Separating and quantifying facility-level methane emissions with overlapping plumes for spaceborne methane monitoring

Published: January 2025

Abstract. Quantifying facility-level methane emission rates using satellites with fine spatial resolution has recently gained significant attention. However, the prevailing quantification algorithms usually require the methane column plume from a solitary point source as input. Such approaches are challenged with overlapping plumes from multiple point sources. To address these challenges, we propose a separation approach based on a heuristic optimization and the multi-source Gaussian plume model to separate the overlapping plumes. Subsequently, the integrated mass enhancement (IME) model is applied to accurately quantify emission rates. To validate the proposed method, observation system simulation experiments (OSSEs) of various scenarios are performed. The result shows that plume overlapping exacerbates the quantifying error of the IME method when applied without such a separation approach, where the quantification mean absolute percentage error (MAPE) increased from 0.15 to 0.83, and it is affected by factors such as source intervals, wind direction, and interference emission rates. By contrast, the application of the proposed separation method together with the IME quantification approach mitigates this interference, reducing the quantification MAPE from 0.83 to 0.38. Moreover, the proposed method also outperforms the direct use of multi-source Gaussian plume fitting for the quantification, with a MAPE of 0.45. Our separation method separates overlapping plumes from multiple sources into distinct, single-source observations, enabling the IME algorithm – a high-precision quantification approach for fine-spatial-resolution plume images – to handle multi-source scenarios effectively. This method can help future spaceborne carbon inventory activities for spatially clustering carbon-emitting facilities.

Published: January 2025

Abstract. The highly sensitive Ka-band cloud radar at the Barbados Cloud Observatory (BCO) frequently reveals radar reflectivity signals below −50 dBZ within the convective sub-cloud layer. These so-called haze echoes are signals from hygroscopically grown sea salt aerosols. Within the Cloudnet target classification scheme, haze echoes are generally misclassified as precipitation (target class: “drizzle or rain”). We present a technique to discriminate between “drizzle or rain” and sea salt aerosols in Cloudnet that is applicable to marine Cloudnet sites. The method is based on deriving heuristic probability functions utilizing a combination of cloud radar reflectivity factor, radar mean Doppler velocity, and the ceilometer attenuated backscatter coefficient. The method is crucial for investigating the occurrence of precipitation and significantly improves the Cloudnet target classification scheme for measurements at the BCO. The results are validated against the amount of precipitation detected by the Virga-Sniffer tool. We analyze data for measurements at BCO covering 2 years (July 2021–July 2023). A first-ever statistical analysis of the Cloudnet target classification product including the new “haze echo” target over 2 years at the BCO is presented. In the atmospheric column above the BCO, “drizzle or rain” is on average more frequent during the dry season compared to the wet season due to the higher occurrence of warm clouds contributing to the amount of precipitation. Haze echoes are identified about 4 times more often during the dry season compared to the wet season. The frequency of occurrence of “drizzle or rain” in Cloudnet caused by misclassified haze echoes is overestimated by up to 16 %. Supported by the Cloudnet statistics and the results obtained from the Virga-Sniffer tool, 48 % of detected warm clouds in the dry and wet season precipitate. The proportion of precipitation evaporating fully before reaching the ground (virga) is higher during the dry season.

Published: January 2025

Abstract. Upright folds in ice sheets are observed on the cm-scale in cloudy bands in drill cores and on the km-scale in radargrams. We address the question of the folding mechanism for these folds, by analysing the power spectra of fold trains to obtain the amplitude as a function of wavelength signal. Classical Biot-type buckle folds due to a rheological contrast between layers develop a characteristic wavelength, visible as a peak in the power spectrum. Power spectra of ice folds, however, follow a power law with a steady increase in amplitude with wavelength. Such a power spectrum is also observed in a folded, highly anisotropic biotite schist and in a numerical simulation of the deformation of ice Ih with a strong alignment of the basal planes parallel to the shortening direction. This suggests that the folds observed in ice are primarily due to the strong mechanical anisotropy of ice that tends to have a strong lattice preferred orientation due to ice-sheet flow.

Abstract. In this study, we present a fully automated aerosol mass spectrometer (AMS) that is operated during regular passenger aircraft flights in the CARIBIC (Civil Aircraft for the Regular Investigation of the Atmosphere Based on an Instrument Container) part of the European Research Infrastructure IAGOS (In-service Aircraft for a Global Observing System – www.iagos.org). The instrument, termed CARIBIC-AMS, is able to measure the mass concentration of non-refractory aerosol species, namely sulfate, nitrate, ammonium, and organics, in a particle diameter range of approximately 50 – 800 nm. The main challenge was the mechanical and electrical redesign of a commercial instrument in order to comply with the operating and safety requirements in the IAGOS-CARIBIC container-laboratory before and during flight. In the container-laboratory, the instrument has to operate fully autonomous, typically during four consecutive long-haul flights à 10 hours. The CARIBIC-AMS weighs 74 kg, has a volume of 0.16 m3 and consumes 360 W of electrical power during regular operation. Due to short time for evacuation of the vacuum chamber to sufficiently low pressures before measurement, detection limits are higher during regular flights than during ground operation and were determined to be 0.035 µg m-3 STP (sulfate), 0.055 µg m-3 STP (nitrate), 0.69 µg m-3 STP (organics), and 0.38 µg m-3 STP (ammonium) for a time resolution of 30 seconds. Since the IAGOS-CARIBIC project aims for climatological, regular, long-term data, longer data averaging times are possible, thereby lowering the detection limits accordingly. For 5-minute averaging, for instance, the above detection limits correspond to 0.011 µg m-3 STP (sulfate), 0.017 µg m-3 STP (nitrate), 0.22 µg m-3 STP (organics), and 0.12 µg m-3 STP (ammonium). Data validation, calibration and instrument characterization were conducted by means of laboratory-based comparisons with existing, established aerosol mass spectrometers. Here we report on the details of the automation, the instrument characterization as well as first in-flight data measured in the upper troposphere and lower stratosphere during two IAGOS-CARIBIC flights and during the TPEx (Tropopause composition gradients and small-scale mixing Experiment) field campaign, conducted in 2024 using a Learjet as research aircraft over Northern Europe.
Sub-shelf melt pattern and ice sheet mass loss governed by meltwater flow below ice shelves
Authors: Jesse Franka , Lambert Erwin , van de Wal Roderik S. W.
Published: January 2025

Abstract. Ocean-induced sub-shelf melt is one of the main drivers of Antarctic mass loss. Capturing it in ice sheet models is typically done by using parameterisations that compute sub-shelf melt rates based on local thermal forcing. However, these parameterisations do not resolve the 2D horizontal flow of the meltwater layer, either neglecting it entirely or simplifying its representation. In this study, we present a coupled setup between the ice sheet model IMAU-ICE and the sub-shelf melt model LADDIE. LADDIE resolves 2D horizontal meltwater flow beneath an ice shelf, incorporating both topographic steering and Coriolis deflection of meltwater plumes. We conduct simulations in a framework closely resembling the Marine Ice Sheet Model Intercomparison Project third phase (MISMIP+), which represents an idealised ice sheet-shelf system. Simulations using LADDIE to calculate melt rates reveal key differences compared to simulations using the widely adopted sub-shelf melt parameterisations. These differences primarily emerge as variations in timing, location, and persistence of strong melting, leading to distinct transient volume loss. In the LADDIE experiments, a stepwise increase in ocean temperatures induces an initial steepening of the ice draft near the grounding line. This strengthens the westward flow, which converges into a western boundary channel, leading to persistent strong melting along the western margin. Consequently, western margin thinning results in reduced buttressing and strong volume loss over the first period of the simulations. Over longer timescales, a weakened meltwater flow circulation due to reduced thermal forcing at the grounding line allows the western margin to thicken again, suppressing volume loss. In contrast, the parameterisation's limitations in representing the 2D horizontal meltwater flow prevent these experiments from capturing the influence of ice draft steepening on enhanced margin melt. This results in a different transient volume loss compared to LADDIE. The parameterisations either inherently overestimate the persistence of margin thinning, leading to a sustained strong volume loss, or they underestimate margin thinning, delaying the onset of strong volume loss. Our findings suggest that incorporating the more detailed melt patterns resulting from the 2D horizontal meltwater flow in ice sheet models could significantly alter projections of Antarctic ice sheet evolution compared to melt patterns computed by the currently more common parameterisations.

Published: January 2025

Abstract. This work presents a field study measuring aeolian sediment transport and wind profiles across a dune, and provides an approximation of the annual volume of aeolian transport into the dune systems of the East Frisian island of Spiekeroog, using commonly available meteorological data. Aeolian sediment traps were positioned along a transect aligned with the general wind direction during the measurement, starting on the open beach and ending on the back site of a selected dune. Wind profiles were temporarily measured next to four aeolian traps. Using a recent version of an aeolian sediment transport model, the total annual aeolian sediment transport into the dune systems is approximated. Input variables for this model are the time series of shear velocity and surface moisture. These are derived from the wind velocity measured at a height of 10 m and the amount of precipitation in combination with potential evaporation calculated using radiation intensity. The results are compared to volume changes of the beach and dune systems, which are derived from geospatial data. Data from the field study shows, that sediment transport occurs even behind twenty metres of vegetation on top of a dune. Further, the study indicates that the impact of precipitation on aeolian transport reduction can be lower within vegetated areas on a dune compared to the open beach. The approximation of the total annual aeolian transported sediment surpasses the actual volume changes of the dune systems as expected, however this difference varies depending on the compared beach section almost by a factor of five.

Published: January 2025

Abstract. Preventing and fighting forest fires has been a challenge worldwide in recent decades. Forest fires alter forest structure and composition; threaten people's livelihoods; and lead to economic losses, as well as soil erosion and desertification. Climate change and related drought events, paired with anthropogenic activities, have magnified the intensity and frequency of forest fires. Consequently, we analysed forest fire susceptibility (FFS), which can be understood as the likelihood of fire occurrence in a certain area. We applied a random forest (RF) machine learning (ML) algorithm to model current and future FFS in the federal state of Brandenburg (Germany) using topographic, climatic, anthropogenic, soil, and vegetation predictors. FFS was modelled at a spatial resolution of 50 m for current (2014–2022) and future scenarios (2081–2100). Model accuracy ranged between 69 % (RFtest) and 71 % (leave one year out, LOYO), showing a moderately high model reliability for predicting FFS. The model results underscore the importance of anthropogenic parameters and vegetation parameters in modelling FFS on a regional level. This study will allow forest managers and environmental planners to identify areas which are most susceptible to forest fires, enhancing warning systems and prevention measures.

Published: January 2025

This study examines the role of microfinance institutions in supporting the development of Micro, Small, and Medium Enterprises (MSMEs), with a case study on Budi Gadai, located on Jalan Pancing. The objective of this research is to analyze how microfinance, particularly Budi Gadai, contributes to the growth and sustainability of MSMEs through accessible financing and financial management guidance. The research employs a qualitative approach with in-depth interviews and analysis of business performance data from MSME clients of Budi Gadai. The findings indicate that Budi Gadai provides a significant impact on MSME growth by offering simplified loan access, which helps business owners overcome financing barriers. The majority of MSMEs reported increased revenue and business expansion after obtaining funding from Budi Gadai. However, challenges remain, such as high interest rates and limited loan amounts. Nevertheless, Budi Gadai plays a critical role in the economic resilience of MSMEs, especially during periods of financial crisis. This study concludes that microfinance institutions like Budi Gadai are essential for the sustainability and growth of MSMEs, particularly in urban areas.

Published: January 2025

Domestic violence is a pressing and emerging issue in Pakistan, deeply rooted in societal norms and power dynamics. This study aims to analyze the current state of domestic violence in the country and its profound impact on other family members. Conducted as a descriptive study, data was gathered from existing research reports, academic studies, and government and non-governmental organization publications. The findings reveal that men hold a dominant role in Pakistani society, wielding substantial power over domestic affairs, while women are often perceived as the weaker gender. This imbalance contributes to the alarming frequency of domestic violence cases reported daily. Common forms of domestic violence in Pakistan include physical abuse, murder, abduction, assault, acid attacks, and other violent acts. A significant driver behind this brutality is poverty, which exacerbates the patriarchal structure that dominates the culture. Domestic violence not only affects the victims but also has severe social and psychological repercussions on other family members, perpetuating cycles of trauma and instability within communities. The study concludes that domestic violence remains a persistent challenge in Pakistan, with detrimental effects on societal well-being.
The Smart City Policy and Urban Public Service Delivery: A Quantitative Study Under the Background of COVID-19 Pandemic
Authors: Xu Nini , Chen Dingxiang
Published: January 2025

The aim of this study is to empirically investigate the contributions of smart city policy (SCP) in promoting urban public service delivery during the COVID-19 pandemic. The effect of the pandemic on urban public service delivery is evaluated using a continuous difference-in-differences (DID) methodology based on a sample of 200 cities in China. On that basis, a triple-difference (DDD) model is built to evaluate the mitigation effect of SCP. The results indicate that the COVID-19 pandemic has significantly hindered urban public service delivery. SCP is capable of significantly mitigating the negative effect of the pandemic on urban public service delivery. Moreover, cities with a larger scale and better location advantage are subjected to a more significant mitigation effect of SCP, as revealed by the heterogeneity analysis results. The findings of this study provide useful empirical evidence for policy-makers and urban planners and significant practical implications for facilitating smart city construction and boosting urban public service delivery in the future.

Em razão do crescimento massivo populacional, houve grande aumento da produção do agronegócio no Brasil, uma vez que o país é um dos maiores produtores de lavoura e pecuária do mundo. Ocorre que esse crescimento acaba acarretando aumento da degradação ambiental, sendo necessárias medidas para mitigá-la. A Integração Lavoura-PecuáriaFloresta (ILPF) tem apresentado resultados que indicam a sua contribuição para uma agropecuária sustentável. Apesar de dispor de previsão legal, o sistema necessita de uma implementação efetiva. Portanto, este artigo tem como objetivo analisar a ILPF através do comportamentalismo econômico e das falhas de escolha dos produtores rurais. A regulação econômica da atividade econômica pode contribuir para a efetivação da ILPF? Se afirmativo, como? A princípio, o poder de polícia contemporâneo ajudará na implementação da ILPF e na diminuição dos erros de escolha das partes envolvidas. Utilizou-se a metodologia teórico-documental, com raciocínio dedutivo. Concluiu-se que os mecanismos de regulação econômica da atividade devem ser utilizados para a efetivação do sistema através do tratamento das falhas na escolha dos produtores rurais.

Published: January 2025

O Direito Humano à Alimentação Adequada (DHAA), estabelecido pelo Pacto Internacional dos Direitos Econômicos, Sociais e Culturais (PIDESC), garante o acesso a uma alimentação suficiente e segura. No Brasil, esse direito foi incorporado à Constituição pela Emenda Constitucional nº 64 de 2010, que exige ações do governo para sua implementação. A Política de Salário Mínimo, essencial para cobrir as necessidades básicas, está ligada ao DHAA, mas a atual Cesta Básica Nacional está desatualizada e precisa ser revista para refletir as necessidades nutricionais contemporâneas e garantir uma alimentação digna. Desse modo, este trabalho objetivou analisar, por meio de levantamento bibliográfico, os limites e possibilidades do salário mínimo brasileiro como meio de garantir o poder aquisitivo a um trabalhador adulto. Assim, este trabalho explora o papel da política de salário mínimo como um instrumento crucial para garantir o Direito Humano à Alimentação Adequada (DHAA) às camadas sociais mais vulneráveis. A pesquisa, baseada em documentos de várias instituições e publicações sobre a cesta básica, salário mínimo e alimentação adequada, analisa a eficácia do salário mínimo na promoção do DHAA. O estudo está dividido em três partes: a primeira aborda a importância do DHAA na garantia dos direitos humanos; a segunda examina a Política de Salário Mínimo, seus aspectos históricos e metodológicos; e a terceira avalia a composição nutricional da Cesta Básica Nacional, buscando entender como a política de salário mínimo pode ser aprimorada para melhor garantir o DHAA.

A transição da modernidade para a pós modernidade, os avanços das tecnologias, as novas mídias, as redes sociais, os jogos e todas as formas de interação virtuais revelam um cenário propício para construção de personalidades a partir de identidades fracionárias, ante a múltiplas possibilidades do exercício de si mesmo. Constitui-se um contexto de singularidades e instabilidades identitárias com impactos nos sujeitos de direitos, no exercício dos direitos humanos, sobretudo no direito de existir. A proteção jurídica dos sujeitos para além do mundo material, plano radical do direito moderno, impõe revisitar os conceitos de sujeito e de identidade vislumbrando a historicidade das construções jurídicas e  o  plano axiológico em que se desenvolvem as relações intersubjetivas. Na perspectiva crítica, os direitos humanos, notadamente a dignidade plena, devem alcançar os sujeitos em todas as suas dimensões. Esta é a reflexão trazida neste estudo. Trata-se de uma perspectiva pluridisciplinar, crítico-analítica, realizada a partir da pesquisa bibliográfica.
Toward a Future-Facing Climate Policy
Authors: Farber Daniel A.
Published: January 2025

This Article provides a systems analysis of climate change policy that links together subsystems relating to innovation, energy economics, interest group politics, and government regulation. It is easy but misleading to equate climate policy with emissions regulation. That is too narrow a frame. We urgently need a new energy system because of climate change, but regulating carbon emissions is only one part of a bigger project. We cannot assume that as carbon emissions decline a new energy system will build itself—nor will society be willing to eliminate fossil fuels without confidence in their replacements.
An effective climate policy requires much more than simply restricting fossil fuels and hoping the market will fill the gap. The energy transition requires incentives for energy research, development, and scaling up new energy technologies. For the energy transition to happen, we also need sufficiently large-scale deployment to trigger economies of scale and learning by doing. There is much to be gained, then, from shifting the paradigm from emissions reduction to the energy transition. To make a homely analogy: The reason for a kitchen renovation may be dry rot, and the first step is ripping out rotten wood. But the point of the remodeling is putting in a new kitchen, not just getting rid of the rot.
A influência da filosofia política de matriz norte – americana na Confederação do Equador

O trabalho tem como objetivo refletir a respeito do ideário político publicizado pelos cearenses envolvidos na Confederação do Equador durante o ano de 1824, atentando-se para contribuição e compreensão da filosofia política republicana, de matriz norte-americana, no movimento e sua influência na elaboração de uma experiência particular de república em consonância com os ideais autonomistas defendidos pelos liberais pernambucanos. Para isso, serão pontuados as aproximações e distanciamentos a respeito dos conceitos de confederação e federação e a interpretação destes nos discursos e ambições difundidos pelos confederados cearenses como alternativa política a ser implementada no Brasil como forma de protesto diante dos acontecimentos políticos sucedidos no país entre 1823/24, principalmente os que se referem a dissolução da Assembleia Geral Constituinte, a suposta investida militar portuguesa contra o Brasil e o modelo de governo visto como despótico e centralizador estabelecido por D. Pedro I via Carta Constitucional em março de 1824.

Published: January 2025

Introduction: This study represents a literature review on the participation of the brain reward system in harmful situations. Objective: The study aimed to analyze and examine the scientific literature regarding the involvement of the reward system in behaviors that generate suffering, highlighting the neurobiological influences in the process and identifying the brain structures in which dopamine plays a part. Method: This is a descriptive and qualitative literature narrative review conducted by cross-referencing the following descriptors: Neurochemistry AND Motivation; Neuroquímica AND Motivação; Neuroanatomy AND Motivation, applied in the Bvs and PubMed databases. Results: Based on the considered studies, significant neurological influences in the motivational process were observed. The brain regions with the highest involvement were identified as the nucleus accumbens followed by the shell regions of the nucleus accumbens, basolateral amygdala, prefrontal cortex, and hypothalamus, along with other areas such as the mesencephalon, anterior cingulate cortex, ventral striatum, amygdala, and ventral tegmental area. Furthermore, neurochemical substances involved in the motivation process were found, with emphasis on glutamate, dopamine, and mesolimbic dopamine. Conclusion: Through the articles included in the sample, it was observed that dopamine and the reward system play a role in behaviors of suffering or harm when associated with goal attainment. In other words, these behaviors are maintained, even if harmful, when there is an interpretation that there will be future gain to some degree and intensity. This finding supports the initial hypothesis of the article for possible confirmation.

Published: January 2025

Este artigo apresenta resultados de uma sondagem realizada sobre dificuldades de estudantes de graduação, matriculados na disciplina que a autora do artigo leciona, denominado de Trabalho de Conclusão de Curso, do curso de Pedagogia do Centro de Educação da UFPE. O objetivo foi compreender os principais motivos que, segundo as percepções desses participantes, dificultam a elaboração do projeto de pesquisa, assim como a escrita do artigo final. A metodologia da pesquisa foi qualitativa, configurada como uma pesquisa de campo, analisada e interpretada através da técnica de análise de conteúdo. O aporte teórico se apoiou nos construtos de autores do campo da metodologia da pesquisa e da teoria crítica de educação enquanto processos interrelacionados. Os resultados demonstram que as dificuldades mais profundas se localizam na escrita acadêmica e na escassa prática de pesquisa ao longo de todo o processo formativo, inclusive na universidade.
A simple 2D multibody model to better quantify the movement quality of anterior cruciate ligament patients during single leg hop

Published: January 2025

Patients with anterior cruciate ligament reconstruction frequently present asymmetries in the sagittal plane dynamics when performing single leg jumps but their assessment is inaccessible to health-care professionals as it requires a complex and expensive system. With the development of deep learning methods for human pose detection, kinematics can be quantified based on a video and this study aimed to investigate whether a relatively simple 2D multibody model could predict relevant dynamic biomarkers based on the kinematics using inverse dynamics.

Six participants performed ten vertical and forward single leg hops while the kinematics and the ground reaction force “GRF” were captured using an optoelectronic system coupled with a force platform. The participants are modelled by a seven rigid bodies system and the sagittal plane kinematics was used as model input. Model outputs were compared to values measured by the force platform using intraclass correlation coefficients for seven outcomes: the peak vertical and antero-posterior GRFs and the impulses during the propulsion and landing phases and the loading ratio.

The model reliability is either good or excellent for all outcomes (0,845 ≤ ICC ≤ 0.987).

The study results are promising for deploying the developed model following a kinematics analysis based on a video. This could enable clinicians to assess their patients’ jumps more effectively using video recordings made with widely available smartphones, even outside the laboratory.

The purpose of this study was to evaluate the radiographic outcomes of distal chevron metatarsal osteotomy associated with lateral joint capsule split as only lateral soft tissue release in patients with symptomatic moderate and severe hallux valgus (HV) deformity.

Ninety patients (103 feet) at our institution between January 2014 and December 2019 were included in the present retrospective study.

Each patient was evaluated preoperatively and at final follow-up by means of weight bearing radiographs lateral and dorsoplantar views. We analyzed hallux valgus angle (HVA), first-second intermetatarsal angle (IMA) and medial sesamoid position (MSP).

The mean follow-up time was 21.8 months (range 6-69.4).

The mean of the HVA improved, from 36.6 to 24.3º, the IMA from 13.05 to 9.93º and the MSP from 2 to 1.

Our study demonstrates that the deformity recurrence rate after surgery is 69.9%. Radiologic HV recurrence was defined by a final HVA equal or more than 20 degrees at final follow-up.

To date, no Dutch questionnaire exists to administer preoperative patient expectations in patients scheduled to undergo a total shoulder arthroplasty. The aim of this study is to develop a Dutch translation of the Hospital for Special Surgery Expectations Survey using a standardized translation procedure, to use both in clinical practice and in scientific research.

Translation is performed on the basis of a forward - backward translation. The clarity of the pre-final Dutch version is tested on 10-30 patients scheduled to undergo a total shoulder arthroplasty. The answers of the patients are studied prospectively at a single time point.

All the questions of the Hospital for Special Surgery Expectation Survey are clear to more than 80% of patients, which is the norm value where it can be assumed that the question is clearly understandable.

The Dutch version of the Hospital for Special Surgery Expectations Survey can be considered clear, as all questions did not give any ambiguities for 80% of the patients. This study provides a foundation needed for further research to assess the psychometric properties of the Dutch translation of the Hospital for Special Surgery Expectations Survey.

TKA is routinely done orthopaedic procedure done that aims at improving the quality of patients’ life by providing pain relief, functional improvement and deformity correction. This study aims to study the efficacy and safety of a Periarticular analgesic cocktail including ropivacaine injection and epidural ropivacaine for early rehabilitation after a total knee replacement. Methods: Total of 100 patients divided into two groups, one group received epidural ropivacaine and second group given periarticular cocktail containing ropivacaine. Then postoperatively their pain score comparison using VAS score and their functional status is documented knee society score. Results: The mean age for the epidural group is 60.28 years, while for the periarticular cocktail group it’s 60.88 years. For female patients, 34 (68%) received epidural analgesia, while 24 (48%) received periarticular cocktail. Among male patients, 16 (32%) had epidural analgesia, and 26 (52%) received periarticular cocktail. For pre-operative pain scores, patients receiving Epidural analgesia had a slightly higher mean score of 7.24 compared to those receiving Periarticular Cocktail, who had a mean score of 7.12. Patients in the Epidural group had a higher mean knee flexion of 83.84 degrees compared to the Periarticular Cocktail group, which had a mean flexion of 79.36 degrees. The Knee Society Scores (KSS) for the post-operative scores; The Epidural group had a mean score of 80.16. The Periarticular Cocktail group had a mean score of 88.40. Conclusion: In conclusion, this study supports the periarticular analgesic cocktail over epidural analgesia for pain management and early rehabilitation following TKR.

Published: January 2025

Despite advancements in surgical techniques for rotator cuff repair, retear rates remain a significant concern. This study systematically reviews the evidence on the effectiveness of the Regeneten Bioinductive Implant in improving healing outcomes. A systematic review of the literature was conducted by searching on PubMed, Embase, Web of Science Core Collection and Cochrane Library. Studies reporting on effectiveness, safety, radiological, clinical outcomes, or patient- reported outcomes after Regeneten use, with at least 12 months of follow-up, were considered. 17 articles were included in this review, encompassing data on 1062 rotator cuff tears, of which 966 were treated with Regeneten. The implant use resulted in retear rates of 0% up to 18% after 5 years in PT tears and 0% up to 35% after 2 years in FT tears. In 1 randomised trial, the retear rate was significantly lower in the implant group compared to the control group. Constant- Murley Score (CMS) and the American Shoulder and Elbow Surgeons (ASES) score showed a sustained improvement compared to pre-operative scores across all studies. MRI showed increased tendon thickness starting from 6 months, with MRI signals suggesting that the implant was integrating with the native tendon and becoming indistinguishable. While using Regeneten for rotator cuff tears of various sizes and chronicity is associated with reduced retear rates in some studies, the clinical outcomes remain within the same range as those seen with traditional rotator cuff repair. Additional randomized controlled trials are required to validate these results and clarify the appropriate indications for using this implant.

Many studies show that repeating a year primarily concerns students who repeat a year. Rarer are those that highlight the consequence of its absence, the automatic passage. However, it has an impact on the dynamics of the classroom and therefore potentially on the way in which students co-construct their learning. The short exploratory study presented below aims to begin an observation on this phenomenon.
