Measurement report: The ice-nucleating activity of lichen sampled in a northern European boreal forest
Authors: Proske Ulrike , Adams Michael P. , Porter Grace C. E. , Holden Mark A. , Bäck Jaana , Murray Benjamin J.
Published: January 2025

Abstract. Ice-nucleating particles (INPs) facilitate the heterogeneous freezing of cloud droplets and thus modify cloud properties. Hence, it is important to understand the sources of INPs. During the HyICE-2018 campaign, which took place in the boreal forest of Hyytiälä, substantial concentrations of airborne heat-sensitive biological INPs were observed, despite many potential biological sources of INPs being snow-covered. A potential source of INPs that were not covered in snow was lichens that grow on trees; hence, we investigated these lichens as a potential source of biological INPs in this boreal forest environment. INPs derived from lichen sampled during HyICE-2018 are shown to nucleate ice at temperatures as warm as −5 °C with 103 INPs per gram of lichen. Successive filtration to smaller sizes removes some of the most active INPs in suspension, but substantial activity remains, even when filtering to 0.1 µm. The small size of the INPs from lichen means they have the potential to either be emitted directly into the atmosphere or be associated with larger particles, such as lichenous reproductive aerosol types (spores or diaspores). We also show that the INPs from lichens from Hyytiälä are sensitive to heat, which is similar to the INPs sampled from the atmosphere of Hyytiälä and consistent with the presence of ice-active proteins. Adding to previous evidence of lichenous INPs, this study shows that lichens from a European boreal forest in Hyytiälä harbour INPs. This novel finding may be especially important in this snow-covered habitat where few, if any, other biological INP sources are available. The great terrestrial abundance of lichens in Hyytiälä, and around the world, calls for further research to combine their ice-nucleating ability with dispersal studies to evaluate the flux of lichenous INPs into the atmosphere, as well as to what extent these particles reach heights and locations where they might influence cloud properties.

Published: January 2025

Abstract. Underwater gliders equipped with current profilers and optical turbidity sensors offer a low-energy solution for high-resolution measurements of currents, suspended particle properties, and sediment transport in coastal waters. Because the spatial structure of hydrosedimentary processes often changes on short time scales (hours to weeks), especially in coastal areas, validating the distribution of glider observations is required to assess our capacity to represent hydrosedimentary processes. Here we propose to validate in a shelf tide-dominated environment, both i) glider-based currents, and ii) glider-based acoustic backscatters and optical turbidities in full resolution delayed mode, using in situ colocated and synchronous ancillary observations. The deployed glider system correctly measures the periodic pattern of the tidal current, with a satisfying RMSD of O(3 cm s -1). Glider optical turbidities highly correlate with the ancillary observations (R2 up to 0.83). They also correlate well with their glider acoustic counterpart for most of the campaign period (R2 = 0.76), allowing an estimation of suspended particulate matter concentrations from the acoustic. In this study, we showed the presence of bottom nepheloid layers of several mg·l-1 on the shelf probably due to advection of coastal turbid waters as evidenced by estimated glider sediment fluxes. These results highlight the potential of gliders for quantifying sediment fluxes and advancing our understanding of coastal hydrosedimentary processes.
Past, Present, and Future Variability of Atlantic Meridional Overturning Circulation in CMIP6 Ensembles
Authors: Coquereau Arthur , Sévellec Florian , Huck Thierry , Hirschi Joël J.-M. , Jamet Quentin
Published: January 2025

Abstract. The Atlantic Meridional Overturning Circulation (AMOC) is a key component of the climate system, exhibiting strong variability across daily to millennial timescales and significantly influencing global climate. Sensitive to external conditions such as freshwater input, greenhouse gas concentrations, and aerosol forcing, important variations of the AMOC can be triggered by anthropogenic emissions. This study presents a comprehensive analysis of sources of AMOC variance in state-of-the-art climate ensemble models. By decomposing the effects of scenario, model, ensemble, and time variability, along with their interactions, through an Analysis of Variance (ANOVA), we identify three distinct regimes of AMOC variability from 1850 to 2100. The first regime, spanning most of the historical period, is characterized by a relatively stable AMOC dominated by internal variability. The second regime, initiated by AMOC decline at the end of the 20th century and lasting until mid-21st century, is governed by a transient increase of time variability. Notably, the direct effect of forcing differences remains muted all along this regime, despite the start of emission-scenarios in 2015. The third regime, beginning around 2050, is marked by the emergence and rapid dominance of inter-scenario variability. Throughout the simulations, model variability remains the primary source of uncertainty, influenced by aerosol forcing response, AMOC decline magnitude, and the physical variability. A key finding of this work is the evidence that internal variability decreases simultaneously with AMOC intensity and seems proportional to emission-scenario intensity.
Imputation of missing land carbon sequestration data in the AR6 Scenarios Database
Authors: Prütz Ruben , Fuss Sabine , Rogelj Joeri
Published: January 2025

Abstract. The AR6 Scenarios Database is a vital repository of climate change mitigation pathways used in the latest Intergovernmental Panel on Climate Change (IPCC) assessment cycle. In its current version, many scenarios in the database lack information about the level of anthropogenic carbon dioxide (CO2) removal via land sinks, as net-negative CO2 emissions and gross removals on land are not always separated and are not consistently reported across models. This makes scenario analyses focusing on CO2 removal challenging. We test and compare the performance of different regression models to impute missing data on land carbon sequestration for the global level and for several sub-global macro-regions from available data on net CO2 emissions from agriculture, forestry, and other land uses. We find that a k-nearest neighbors regression performs best among the tested regression models and use it to impute and provide two publicly available imputation datasets (https://doi.org/10.5281/zenodo.13373539, Prütz et al., 2024) on CO2 removal via land sinks for incomplete global scenarios (n=404) and incomplete regional R10 scenario variants (n=2358) of the AR6 Scenarios Database. We discuss the limitations of our approach, the use of our datasets for secondary assessments of AR6 scenario ensembles, and how this approach compares to other recent AR6 data reanalyses.
Residential heating emissions for the Western Balkans
Authors: Asker Christian , van Dongen Eef , Tasse Olivier
Published: January 2025

Abstract. Air pollution adversely effects health, ecosystems and infrastructure. In the Western Balkans (Albania, Bosnia and Herzegovina, Kosovo1, Montenegro, Republic of North Macedonia and Serbia), the air pollution situation is more adverse than in the European Union in general. Understanding the air quality situation requires high quality emission data, with high resolution spatial distribution, especially for enabling remediation efforts. In this work we have calculated air pollution emissions from heating of individual housing units in the Western Balkan region. The basis for the dataset is a geographical dataset of buildings detected from satellite imagery by artifical intelligence (AI) methods. The building data has been combined with geospatial landuse datasets as well as statistical data for heating needs for residential buildings in the countries included, and finally with emission factors to calculate the heating emissions. The resulting datasets provides high-resolution heating emission data for common pollutants and are published as open data (Asker, 2024) . When comparing national totals for emissions, the datasets in this work are comparable to other, spatially coarser datasets, though the agreement strongly depends on the fuel usage data for each country/region. 1All references to Kosovo in this document shall be understood to be in the context of the United Nations Security Council resolution 1244 (1999)

Published: January 2025

Abstract. South America is a global hotspot for land use and land cover (LULC) change, marked by dramatic agricultural land expansion and deforestation. Developing high-resolution, long-term crop-specific data is essential for gaining a deeper understanding of natural-human interactions and addressing the impacts of human activities on regional biogeochemical, hydrological cycles, and climate. In this study, we integrated multi-source data, including high-resolution remote sensing data, model-based data, and historical agricultural census data, to reconstruct the historical dynamics of four major commodity crops (i.e., soybean, maize, wheat, and rice) in South America at annual time scale and 1 km×1 km spatial resolution from 1950 to 2020. The results showed that cropland in South America has expanded rapidly through encroachment into other vegetation over the past 70 years. Specifically, soybean is one of the most dramatically expanded crops, increasing from essentially zero in 1950 to 48.8 Mha in 2020, resulting in a total loss of 23.92 Mha of other vegetation (i.e., forest, pasture/rangeland, and unmanaged grass/shrubland). In addition, the area of maize increased by a factor of 2.1 from 12.7 Mha in 1950 to 26.9 Mha in 2020, while rice and wheat areas remained relatively stable. The newly developed crop type data provide important insights for assessing the impacts of agricultural land expansion on crop production, greenhouse gas emissions, and carbon and nitrogen cycles in South America. Moreover, these data are instrumental for developing national policies, sustainable trade, investment, and development strategies aimed at securing food supply and other human and environmental objectives in South America and other regions. The datasets are available at https://doi.org/10.5281/zenodo.14002960 (Xu et al., 2024).
The German Small Lake and Pond Inventory
Authors: Wachholz Alexander , Schmidt Susanne Isabel , Arle Jens , Völker Jeanette
Published: January 2025

Abstract. Small lakes and ponds are hotspots of biodiversity, biogeochemical reactions, and hydrological interactions in the landscape. While mostly providing the same functions as larger lakes, they often do so at higher rates per unit area. Exponentially more abundant than larger lakes, small lakes, and ponds contribute significantly to biodiversity, nutrient retention, and the water budget, even at large spatial scales. However, they are rarely considered in regional or larger-scale environmental studies, partly due to a lack of data. To alleviate this, we developed the German Small Lake and Pond Inventory (GSLPI), a comprehensive database of over 260.000 small lakes and ponds ranging in size from 10 to 500.000 m2 (50 ha or 0.5 km2). Using only openly available data from Germany’s federal states, we provide information on lake or pond location, shape, depth, volume, and connectivity. With this database, we aim to facilitate the integration of small lakes and ponds into environmental research and enhance understanding of their roles within changing landscapes.

Este artigo tem como objetivo testar um aspecto da pesquisa de mestrado com foco para as características formais que compõem a Rua 13 de Junho, área de transição entre Zonas de Interesse Histórico (ZIH) em Cuiabá. São pensadas em novas narrativas para o estudo da paisagem desse caminho entre o Centro Antigo – ZIH 1 e a Orla do Porto – ZIH 2, que contribuam para a percepção das transformações de funções ao longo do tempo, bem como para pensar sobre os impactos práticos que recaem sobre a materialidade reminiscente. Atualmente a via é percebida em fragmentos, fator que instiga um percurso investigativo que explore outras maneiras de compreender essa paisagem. O pontapé inicial do trabalho é dado a partir de algumas considerações sobre as permanências e modificações, focalizadas no contexto da forma para entender as sobreposições temporais. Em um segundo momento, o olhar será voltado para as fissuras do cotidiano, como meio de enxergar para além do que se vê: um processo reflexivo do que a forma nos comunica, seja pensando sobre essas “rugosidades” como resistência, seja como descompassos em relação à dinâmica da cidade. As áreas subutilizadas, no trecho em questão, são formas (antigas) manifestas por meio de ruínas e terrenos baldios. Esses fenômenos, ao revelar a lógica de conformação do núcleo urbano, são produto de possíveis processos abordados aqui como meio de provocação. Por fim, apresenta-se um exercício contracartográfico para pensar a espacialidade de modo mais questionador, indicando possibilidades de investigação histórica a partir de suas inflexões.

"(RE) PRESAS”: COLONIALIDADE RACISTA DE GÊNERO E VIOLÊNCIA CONTRA MULHERES PRESAS NO RIO DE JANEIRO
Authors: Damazio Pinto Ferreira Natália
Published: January 2025

EO artigo elabora sobre as permanências históricas da violência gestada pela prisão aos corpos de mulheres, inclusive suas formas específicas de produção do sofrimento, sendo grande parte dessas violências influenciadas pelas estruturas forjadas durante a colonização na propagação da barbárie capitalista, racista e masculinista. Em termos epistemológicos, será adotada uma perspectiva de análise fundada, principalmente, no pensamento decolonial, na teoria crítica racial e feminismos negros, com base na perspectiva de autoras e autores que experienciam o sistema-mundo a partir do Sul. Recorrendo a essa perspectiva, como ferramenta, será analisada parte das condições materiais da mulher presa no Estado do Rio de Janeiro por meio de relatórios de inspeção do Mecanismo Estadual de Prevenção e Combate à Tortura, assim como de incursões a campo no sistema prisional fluminense por consequência de atuação neste órgão, buscando propor um eixo outro de analise, distinto da perspectiva androcêntrico branca, que pauta parte das análises relacionadas ao encarceramento.

El departamento de Antioquia, ubicado en el noroccidente de Colombia, constituye junto a la región centro-oriental el motor de la economía colombiana al concentrar actividades productivas como minería, generación eléctrica, construcción de grandes obras de desarrollo, entre otras. Tales actividades han generado situaciones de conflicto social y ambiental que han sido analizados durante la última década. La firma de los acuerdos de paz con la guerrilla de las FARC-EP por parte del Estado Colombiano en el año 2016 significó una ventana de oportunidad para resolución de algunos de dichos conflictos ambientales. Esta propuesta describe la manera en que dichos conflictos evolucionaron hacia escenarios de resolución o agudización durante el periodo comprendido entre 2016-2021.
EDUCACIÓN INCLUSIVA Y PAZ: DIÁLOGOS ENTRE LA INCLUSIÓN Y LA NOVIOLENCIA
Authors: Carvajal Gonzalez Juan Daniel
Published: January 2025

La presente investigación se centra en el abordaje de los procesos de exclusión violentos que se dan en la educación, teniendo como objetivo general, analizar la relación existente entre las aulas de clase y los conceptos de la violencia y la noviolencia. Ya que al comprender los espacios de enseñanza como escenarios en donde la violencia se presenta de forma constante, permite indagar las formas en las que se ha venido enseñando desde hace décadas atrás. Esto posibilita el entendimiento de la importancia de que movimientos como la noviolencia surjan en auxilio de todos aquellos segregados que la educación tradicional ha venido creando. En este ejercicio indagatorio, se ha optado por utilizar una metodología de tipo documental, con la finalidad de indagar la incidencia del concepto de violencia en las aulas de clase, para de esta forma conocer la influencia de la noviolencia en los espacios de las aulas de clase y de esta manera, finalmente, comprender la relación entre los conceptos de la violencia y la noviolencia en los espacios de las aulas de clase. Siendo así, los resultados obtenidos después del proceso de análisis, permiten entender que la relación existente entre los espacios de las aulas de clase y los conceptos de la violencia y la noviolencia, es la educación tradicional, entre tanto que esta se presenta como el eje central de toda la problemática de la segregación escolar, entre tanto que esta mide a todos los estudiantes con la misma vara, con los mismos estándares y ello termina por generar una exclusión violenta de todo aquello que no sea normativo, y es ahí en donde surge el dialogo entre la inclusión y la noviolencia, como contraposición a lo establecido por entidades monolíticas como las instituciones educativas que en muchas ocasiones silencian la heteronomía de los estudiantes.
Resisting Static Inertia
Authors: Kubow Grayson
Published: January 2025

This Note analyzes the various approaches that United States courts have taken on the licensing authority of the Nuclear Regulatory Commission as it relates to the private temporary storage of spent nuclear fuel. It seeks to establish a sound statutory basis for the Nuclear Regulatory Commission’s (NRC’s) authority to issue such licenses under the Atomic Energy Act (AEA) by recharacterizing spent nuclear fuel as a “byproduct material” under the meaning of the Act. It then looks to the enumerated uses of byproduct material to establish that the NRC has the authority to issue licenses to the private sector to store spent nuclear fuel. Finally, it will argue that the Nuclear Waste Policy Act (NWPA) could not and should not be interpreted as restricting or superseding the NRC’s existing licensing authority under the AEA. This interpretation of the AEA and NWPA is more reflective of the statutory language and provides for a better nuclear waste policy.

A concepção ameríndia do corpo abre novas possibilidades de pensamento acerca da constituição do sujeito da educação. Com base nesse pressuposto, o presente trabalho almeja compreender a concepção de corpo presente no chamado perspectivismo ameríndio. Trata-se de uma pesquisa teórica voltada ao diálogo com outros sistemas de pensamentos distintos daqueles forjados pela racionalidade moderna. Situada no âmbito da Filosofia da educação, a investigação discute os relatos do líder yanomami Davi Kopenawa registrados no livro A queda do céu. Os resultados permitem apreender uma Bildung sui generis, um complexo processo de formação do humano apoiado na centralidade da figura do xamã tanto no processo de fabricação dos corpos, como na transmissão e difusão dos conhecimentos. Para as populações ameríndias, a educação do sujeito humano emerge, portanto, inseparável dos processos de transformação do corpo. Assim, é possível concluir que as filosofias ameríndias se contrapõem diretamente ao modo hegemônico de situar o corpo nas teorias educativas modernas, sinalizando novos caminhos de investigação.

O processo formativo deve ser eminentemente contínuo. Deste modo, temos por finalidade apresentar os desdobramentos das ações do grupo de estudos e pesquisas da educação em Paulo Freire (GEPEPF, doravante) no interregno do semestre letivo 2023.2 pela teia da interdisciplinaridade a favor da educação em direitos humanos. Mais especificamente, mapear o diretório acadêmico do GEPEPF, escavar as linhas de pesquisa e explicitar as ações decorridas das linhas de pesquisa. Deste modo, partimos da curiosidade epistemológica: Qual é a dinâmica da formação do ser professor na atualidade? A metodologia que melhor coopera para os achados desta curiosidade é a teoria da análise do discurso de Michel Foucault (2008), a qual nos permite mapear, escavar e explicitar o GEPEPF em ação. Assinalamos que o respectivo grupo de estudos e pesquisas tem promovido a inserção dos seus membros com intensidade nas ações de ensino, pesquisa e extensão, bem como indo além, alcançando processos formativos autônomos e criativos de seus membros através da interdisciplinaridade a favor da educação em direitos humanos, sobretudo, para os professores que dele participam.
Comparative outcomes of proximal fibular osteotomy versus high tibial osteotomy in patients with medial knee osteoarthritis: A retrospective analysis
Authors: BAYRAK Hünkar Cagdas , ADIGUZEL Ibrahim Faruk , DEMIR Mahircan , KARAGÖZ Bekir , ORDU Samed
Published: January 2025

High tibial osteotomy (HTO) is a widely used procedure for delaying knee arthroplasty, correcting alignment, and relieving symptoms in patients with knee osteoarthritis. Recently, proximal fibular osteotomy (PFO) has emerged as a less invasive and more cost-effective alternative. This study compares the outcomes of HTO and PFO to evaluate whether PFO can deliver results comparable to HTO in similar patient populations. A total of 96 patients treated between 2018 and 2022 were analyzed, with 54 patients undergoing HTO and 42 undergoing PFO. Subgroups were also created based on body mass index (BMI): non-obese HTO, obese HTO, non-obese PFO, and obese PFO. For each patient, we recorded demographic data, preoperative and 1-year postoperative Oxford Knee Scores (OKS), visual analog scale (VAS) scores, medial joint space (MJS) measurements, mechanical axis deviations (MAD), Kellgren- Lawrence grade (KL), medial proximal tibial angle (MPTA), and any complications. Both HTO and PFO led to significant improvements in OKS, VAS, MJS width, and MAD. Age, KL grade distribution, BMI, and MPTA values were comparable across the groups. Overall, HTO showed superior clinical (OKS, VAS) and radiological (MJS, MAD) outcomes, particularly in non-obese patients. Among obese patients, HTO and PFO achieved similar clinical improvements, although HTO maintained a radiological advantage. Importantly, a lower preoperative MPTA was associated with poorer clinical outcomes in the PFO group. In conclusion, while PFO can produce meaningful clinical and radiological improvements, HTO remains the more effective option in terms of both clinical and radiological outcomes in patients with a BMI below 30. For patients with a BMI over 30, HTO preserves its radiological superiority, although its clinical benefits are comparable to those of PFO. Additionally, a low preoperative MPTA is significantly linked to worse OKS scores in patients undergoing PFO.
Can we DAIR in FRI? Debridement techniques in osteomyelitis
Authors: NEYT J , VICTOR J , CORNU O
Published: January 2025

The concept of Debridement, Antibiotics and Implant Retention (DAIR) is well known in periprosthetic joint infections. Extrapolating this concept to fracture related infections is mired in controversies. Characteristics of the metal implant, duration of infection, state of fracture healing, microbiological profile etc. appear to play a role in the decision making process whether or not to keep, adjust , exchange or remove (infected) metalwork. More than likely it is the quality of source control by meticulous debridement having a major impact whether a DAIR approach to FRI could result in a successful outcome.

Deep venous thrombosis (DVT) has insidious clinical symptoms, and only a few patients suffer from lower limb swelling, tenderness and dorsal flexion pain. We aimed to explore the ultrasonographic features and risk factors of postoperative lower limb DVT in patients with lower limb fractures. Ninety patients with lower limb fractures admitted from January 1st, 2021 to June 30th, 2023 were selected. Color Doppler ultrasonography was performed one month after operation, and the ultrasonographic features were recorded. DVT was diagnosed according to the results of venography, based on which the patients were divided into a DVT group and a non-DVT group. Their basic and treatment-related data were compared. The risk factors for postoperative DVT were screened by multivariate logistic regression analysis. A total of 63 cases were diagnosed with DVT by venography, with a detection rate of 70.00%. A total of 69 cases were diagnosed with DVT by ultrasonography, with a detection rate of 76.67% (P>0.05). The concurrent internal medicine diseases, associated injuries, no preventive measures for thrombosis, operation time ≥2 h, no active or passive exercise after operation, pelvic and proximal femoral fractures, knee fractures and tibiofibular fractures were risk factors for postoperative DVT in patients with lower limb fractures (P<0.05). Ultrasonography is effective for diagnosing postoperative lower limb DVT in patients with lower limb fractures. Related preventive measures should be taken promptly to control the risk factors.

Published: January 2025

This prospective, observational cohort study compares the clinical and radiographic outcomes of the modified Weaver and Dunn (WD) technique with the newer, anatomical double-button plus tendon allograft technique (DB), and the suture anchor repair plus tendon allograft (SA).

The study cohort includes 53 patients, who underwent surgery for acromioclavicular joint (ACJ) dislocation Rockwood type 3, 4 and 5. Patient-reported outcome scores and clinical results, including Disabilities of the Arm, Shoulder and Hand (DASH), the Subjective Shoulder Value (SSV), the Visual Analogue Scale (VAS) and the Constant score (CS) results as well as loss of reduction rates on plain radiographs were compared.

Nineteen patients in the DB group, 19 patients in the SA group and 15 patients in the WD group were included. Average time of follow up was 5 years. The mean VAS scores (SD) were 0.3 (0.6), 0.5 (0.8) and 1.2 (1.4) in the WD, DB and SA groups (p=0.06). There were no significant differences in DASH, SSV and Constant scores between groups.

Loss of reduction on plain radiographs occurred in 4 patients in total (1 WD, 1 DB, 2 SA). The SSV score, the DASH score, the Constant score and the VAS-score revealed no statistically significant differences between the group with good alignment compared to groups with partial reduction or loss of reduction.

In conclusion we can state that the use of anatomical reconstruction techniques with tendon allograft and additional button or suture anchors fixation does not affect the clinical and radiographical outcomes compared to the classic Weaver and Dunn procedure. Loss of reduction was not correlated to worse clinical outcome scores.

The current study aimed to objectively evaluate the fit of a rectangular, tapered stem to the severely dysplastic hips on the basis of the proximal femoral anatomy and the dimensional properties of the stem. It was hypothesized that the stem size planned with accordance to the diaphyseal canal width alone can accommodate the distal femur successfully with no sizing mismatch.

Forty-six patients (53 hips) suffering from secondary osteoarthritis due to hip dysplasia scheduled for total hip arthroplasty (THA) with a subtrochanteric transverse shortening osteotomy were included. All hips were Crowe type 4. All patients underwent preoperative computed tomography imaging. Height of femoral head center (HCH) was determined. Medullary canal diameter measurements at different levels were made. These were made at a level (1) 35% of HCH above the lesser trochanter (DT +35), (2) 70% of HCH below the lesser trochanter (DT -70), and (3) at the level of isthmus (Di). Medullary canal flare indices were calculated from the individual parameter ratios. Similar measurements were carried out for the different sizes of the femoral stem.

The mean DT +35 was 41.9 ± 6.4 mm, the mean DT-70 was 17.3 ± 2.2 mm, and the mean Di was 12.8 ± 1.9 mm. In all femurs, the width of the isthmus was wider than that of the corresponding femoral stem isthmus. The femoral stem sizes established with respect to the diaphyseal width of the femur were all compatible with the isthmus width of the femur.

Tapered and rectangular stems can accommodate the proximal femur above and below the osteotomy level in Crowe type IV hip dyplasia patients, thereby constituting a viable option as the femoral stem in this patient group with technically demanding difficulties.

Percutaneous intra-meniscal platelet-rich plasma (PRP) is a promising tool for managing low-grade meniscal injuries in non-athletic patients. The study evaluates the clinical and radiological outcomes of PRP intra-meniscal injection in meniscal tears. Forty-eight patients were injected with 3 injections of PRP at an interval of one week with a standardised technique under sonographic guidance. All the patients had MRI evidence of meniscal injury with failed conservative management for at least 3 months. The IKDC score and VAS score were recorded initially and during follow-ups. MRI was performed on at least 12 months post-injection. Medial meniscus tear (n=33) was most commonly present. The mean follow-up of the patient was 14.4 months (Range: 12-16 months) except for 1 patient. Horizontal or oblique tears were the most common injury suffered by the patients (n=35). According to MRI classification, 6 patients had grade 1 lesions, 28 patients had grade 2 lesions, and 14 patients had grade 3 lesions. The mean IKDC and VAS scores improved significantly at the last follow-up. Pain at the site of the injection for 1-2 days was the most common adverse effect. Two patients were surgically intervened at 4 and 6 months respectively. Intra-meniscal PRP injection can be a promising modality to manage low-grade meniscal injuries. It is easy, and minimally invasive to manage meniscal tears. Although there was no radiological evidence of healing, clinical improvement was seen in all the patients. Further, long-term randomized studies are required to ascertain the benefits.

Published: January 2025

Chryseobacterium indologenes is a rare human pathogen which is nowadays considered an emerging fearsome organism because of its upcoming antibiotic resistance. We present a quite unique case of a multi drug resistant C. indologenes surgical wound infection in a patient submitted to cannulated screw fixation of a displaced medial malleolus fracture. The microorganism was identified only after three months of attempts to treat pharmacologically the unhealed wound, by removing the ostheosynthesis device and sonicating it, and the surgical wound progressively restored by second intention.

Published: January 2025

Delayed fracture healing (DFH), a common complication of post-fracture surgery, exhibits an incompletely understood pathogenesis. The present study endeavors to investigate the roles and underlying mechanisms of miR-656-3p and Bone Morphogenetic Protein-2 (BMP-2) in DFH. It was recruited 94 patients with normal fracture healing (NFH) and 88 patients with DFH of the femoral neck. Serum miR-656-3p and BMP-2 expressions were quantified using RT-qPCR and the diagnostic potential of them for DFH was evaluated using ROC analysis. Factors influencing fracture healing were identified through logistic regression analysis. Osteogenic differentiation of MC3T3-E1 cells was induced, followed by evaluations of cell proliferation, apoptosis, and differentiation capabilities utilizing CCK-8, flow cytometry, and mRNA expression analysis of osteogenic markers. The targeting relationship between miR-656-3p and BMP-2 was validated through luciferase reporter assays. The levels of miR-656-3p were significantly elevated in DFH patients compared to those with NFH, whereas BMP-2 levels exhibited a decrease, a negative correlation between their expression patterns. Logistic regression analysis revealed that miR-656-3p and BMP-2 serve as influential factors in fracture healing, with their combined assessment exhibiting enhanced predictive value for DFH. Downregulation of miR-656-3p promoted proliferation and differentiation of MC3T3-E1 cells while inhibiting apoptosis. BMP-2, identified as a target of miR-656-3p, negated the effects of miR-656-3p downregulation when BMP-2 expression was inhibited. miR-656-3p modulates osteoblast function by targeting BMP-2, offering novel therapeutic and diagnostic targets for the management of DFH.
