This publication/exposition is the extended version of Falk Hübner's inaugural lecture as professor of Artistic Connective Practices at Fontys Academy of the Arts. The text offers an introduction to the work of the professorship, to the ideas and concepts underpinning it and to its projects and research lines. Rather than presenting finished research, the text seeks to open ideas, insights and imagination and offer a sense of where the journey is heading. With an explicit emphasis on collectively working and thinking together, the core of the publication introduces and elaborates on the concept of artistic connective practices through the notion of three "conceptual clouds": practices, the artistic, and connectivity.
Tidal Zones – Filming Between Life and Images
Authors: Kajsa Dahlberg
Published: May 2024

Informed by queer life practices, theories, and affinities, this documented artistic research project (doctoral thesis) draws from new materialist and post-humanist discourse in order to reconsider what role visual media play in the historical need to separate the human and the environmental. It asks, how do we challenge prevailing perceptions of film and photography as inexorably linked to ideas of progress and modernisation, to linear temporality, spatial separation, and to land-based thought? Based on the acknowledgement that we need to rethink our position as humans within the multiple habitats that make up the world, I investigate the ways in which the apparatus of film, rather than being an extension of human perception, attests to the material interdependences and co-productions that hold a potential for converging human and nonhuman perspectives. "Tidal Zones – Filming Between Life and Images" considers the cinematic space of the ocean alongside Jean Epstein’s film "Le Tempestaire" (1947); it follows early photographic chemical methods involving seaweed to both develop film and to examine the technical intra-activity of human and nonhuman regimes as part of photography itself. Within the scope of this research, I argue and demonstrate how film engages in a sensory and reciprocal involvement with the material world, one that addresses the ability to sense, not just with one’s eyes, but with the entire body.

"Tidal Zones" are real locations, the habitat of a multitude of organisms, and the home of seaweeds. It is a place that is neither land nor sea but constitutes a zone with its own specific relationships and living conditions. In its refusal to be either or, it forms a (non-binary) temporal figuration between presence and absence, solid and liquid, life and death, dictated by the motions of spiral and circular time. This space, "Between Life and Images", is the chemical rockpool (the darkroom) out of which photography and film grew.

The PhD submission consists of four film-works, "The Etna Epigraph" (2022), "Seaweed Film" (2023), "Coenaesthesis – It Is Not Even True That There Is Air Between Us" (2023) and "The Spiral Dramaturgy" (2019) along with the exhibition "The Tidal Zone" shown at Index - The Swedish Con-temporary Art Foundation, Stockholm, from 25 November 2022 to 12 February 2023 and at Havremagasinet, Länskonsthall Boden from 14 October 2023 to 11 February 2024. The films and documentation from the exhibitions are included in the submission, which also includes an “Opening Letter” and two texts called “Filming with the Ocean” and “Methodology of the Spiral”.

This dissertation has been carried out and supervised within the graduate programme in Visual Arts at the Royal Institute of Art. The dissertation is presented at Lund University in the framework of the cooperation agreement between the Malmö Faculty of Fine and Performing Arts, Lund University, and the Royal Institute of Art regarding doctoral education in the subject Visual Arts.

Using a common protocol across seven countries in the European
Union/European Economic Area, we estimated XBB.1.5 monovalent vaccine
effectiveness (VE) against COVID-19 hospitalisation and death in
≥65-year-olds, during October-November 2023. We linked electronic
records to construct retrospective cohorts and used Cox models to
estimate adjusted Hazard Ratios and derive VE. VE for COVID-10
hospitalisation and death was, respectively, 67% (95%CI: 60-72) and
68% (95%CI: 44-82) in 65–79-year-olds, and 64% (95%CI: 49-75) and
74% (95%CI: 56-85) in ≥80-year-olds. Results indicate that periodic
vaccination of individuals ≥65 years has an ongoing benefit, and support
the current vaccination strategies in the EU/EEA.
Shorter telomere length increases the risk of lymphocyte immunodeficiency: A Mendelian randomization study
Authors: Wang Bo , Xiong Yongqiang , Li Ren , Zhang Jiewen , Zhang Shu
Published: May 2024

Background: For a long time, the prevailing viewpoint suggests that
shorter telomere contribute to chromosomal instability, which is a
shared characteristic of both aging and cancer. The newest research
presented that T cell immune deficiency rather than chromosome
instability predisposes patients with short telomere syndromes to some
cancers. However, the relationship between genetically determined
telomere length and immune cells remains unclear. Methods: The
two-sample Mendelian randomization (MR) analysis was conducted to
elucidate the potential causal relationship. The genetic data of
telomere length and the quantity of lymphocytes were obtained from the
Genome-Wide Association Study. The inverse variance-weighted method was
used to estimate the effects primarily and another four methods were as
a supplement. Relevant sensitivity analysis was used to test the
results. Results: The IVW method showed a significant correlation
between telomere length and the percentage of T lymphocytes (OR: 1.222,
95% CI: 1.014-1.472, P = 0.035), indicating that short telomere length
significantly increases the risk of low T cell percentage. Further
analysis of T cell subsets indicated that shorter telomere length may
primarily lead to a lower proportion of Natural Killer T cells (OR:
1.574, 95% CI: 1.281-1.935, P < 0.001). Analysis of B cell
subsets revealed that shorter telomere length may be associated with a
higher proportion of Naive-mature B cells, and a lower proportion of
Memory B cells. And the sensitivity analysis indicated the validity and
robustness of our findings. Conclusion: In summary, a causal
relationship existed between telomere length and the quantity and
differentiation of immune cells. Specifically, genetically predicted
shorter telomere length was found to increase the risk of occurrence of
immunosuppression and immunodeficiency.
Calculation of Drag Coefficient and Friction Factor of Non-Submerged Rigid Vegetation in Symmetric Compound Channel, Using Direct Measurement Method
Authors: Askar Mehdi Behdarvandi
Published: May 2024

Given that the most basic issue in the study of drag coefficient is the
correct and accurate measurement of force, so the use of a method that
can directly measure the force of flow is very important because it can
provide a more realistic analysis of drag coefficient. Also, the results
obtained from this method are compared with the results obtained from
other methods .This research has calculated the drag coefficient and
friction factor using the direct measurement method and physical
modeling in a hydraulic knife-edge flume, which is a particular type of
flume capable of directly measuring the flow force. In this study, five
vegetation diameters, 20, 25, 30, 40, and 50 mm, as well as two types of
ordered and non-ordered arrangement, and three vegetation positions in
floodplains, main channel and simultaneously vegetation in main channel
and floodplain, considering five inline spacing, and three Cross line
spacing between vegetation, which included a total of 451 different
experiments, were examined. In this paper, the φ value is between
0.0017-0.31, and the vegetation’s Reynolds number is in the range
3512-29213. The results revealed that the method and calculations
implemented in the field of drag coefficient are suitably similar to the
drag coefficient obtained from the force balance equation; moreover to
calculate drag coefficient and friction factor in the examined scope, C
D = α 1 ( λ * ) α 2 and f T = β 1 ( Ln λ * + β 2 were achieved based on
the vegetation parameter ( λ * ) . The coefficients of α 1 . α 2 . β 1
 and  β 2 considering the experiments and different position and
arrangement of vegetation were presented.
STRIDE-CH: Sub-Transition Region Identification of Ensemble Coronal Holes
Authors: Landeros Jaime , Kirk Michael S , Arge Charles Nickolos , Boucheron Laura , Zhang Jie , Uritsky Vadim M , Dupertuis Matthew , Grajeda Jeremy
Published: May 2024

Coronal Holes (CH) are large-scale, low-density regions in the solar
atmosphere which may expel high-speed solar wind streams that incite
hazardous, geomagnetic storms. Segmentation of CH boundaries may aid in
validating predictive coronal and solar wind models but has proved
difficult due to similar appearances as filaments and the tendency for
dense coronal plasmas to block underlying CHs in Extreme Ultraviolet
(EUV) imagery. We propose an automated detection algorithm of CHs which
revisits ground-observed, chromospheric He I 10830 Å line imagery and
underlying photospheric magnetograms as drivers to circumvent these
issues and provide a complementary method to the space-observed, coronal
EUV emission-driven methods that have been widely adopted in the
community. Classical computer vision techniques are applied to imbue the
routine with design variables based in radiative and magnetic properties
of CHs, as well as produce an ensemble of boundaries with quantified
intra-algorithm uncertainty. This method is science-enabling towards
future studies of coronal hole formation and variability from a
mid-atmospheric perspective.
Monitoring Salt Domes Used for Energy Storage with Microseismicity: Insights for a Carbon-Neutral Future
Authors: Omojola Joses , Persaud Patricia
Published: May 2024

Underground storage in geologic formations will play a key role in the
energy transition by providing low-cost storage of renewable fuels like
hydrogen. The sealing qualities of caverns leached in salt and
availability of domal salt bodies make them ideal for energy storage.
However, unstable boundary shear zones of anomalous friable salt can
enhance internal shearing and pose a structural hazard to storage
operations. Considering the indistinct nature of internal salt
heterogeneities when imaged with conventional techniques like reflection
seismic surveys, we develop a method to map shear zones using seismicity
patterns in the US Gulf Coast, the region with the world’s largest
underground crude oil emergency supply. We developed and finetuned a
machine learning algorithm using tectonic and local microearthquakes.
The finetuned model was applied to detect microearthquakes in a 12-month
nodal seismic dataset from the Sorrento salt dome. Clustered
microearthquake locations reveal the three-dimensional geometry of two
anomalous salt shear zones and their orientations were determined using
probabilistic hypocenter imaging. The seismicity pattern, combined with
borehole pressure measurements, and sonar surveys show
the spatio-temporal evolution of cavern shapes within the salt dome. We
describe how shear zone seismicity contributed to a cavern well failure
and gas release incident that occurred during monitoring. Our findings
show that caverns placed close to shear zones are more susceptible to
structural damage. We propose a non-invasive technique for mapping
hazards related to internal salt dome deformation that can be employed
in high-noise industrial settings to characterize salt domes used for
storage.

Modeling and Predicting PM2.5 Concentration at a Construction Site Using the Artificial Intelligence
Authors: Manzhilevskaya S. E.
Published: May 2024

Introduction. High concentration of PM2.5 has the adverse effect on people's health. According to the evaluations made by the researchers, the impact of the particulate matter from the construction dust emissions resulted in 18% of deaths from respiratory diseases. Due to the growth of construction production volume and consequent increase of dust emission volumes, there arises the need to expand the scope of using the end-to-end technologies, namely the artificial intelligence technologies, for predicting the fine-dispersed dust particles PM2.5 concentration in dust emissions at the construction site.

Materials and methods. To achieve this goal, the measurements of PM2.5 concentration at the construction site were carried out using the Handheld 3016 IAQ particle counter in the period from July 1 to July 6, 2023 taking into account the meteorological characteristics of the territory, which then became the input data for modelling the forecast of dust pollution concentration using such algorithms as ARIMA, EMA, XGBoost, etc., and the ensemble models that included the above machine learning algorithms. The efficiency of using these technologies for predicting was determined by comparing the results of the forecast and the field measurements data.

Results. A correlation analysis was performed using the Modeltime program, which determined the relationship between PM2.5 concentration and meteorological variables. Autocorrelation was performed using Pearson correlation. At the first stage, four one-dimensional models based on the artificial intelligence were evaluated to determine the accuracy of mean concentration forecast. The next step was to evaluate the capacity of predicting the mean PM2.5 concentration using the multidimensional models that took into account the relationships between the independent and dependent variables. At the final stage of the research, three most efficient predictive models were included to test the ensemble model.

Discussion and conclusion. The reliable predictive models can be the useful tools for understanding the concentration impact factors. In the present research, seven machine learning algorithms were used to predict the concentration of PM2.5. The research, as a whole, presents the evidences of the integrated modeling method efficiency for predicting the air pollution.
Optimisation of Supports’ Position for a Reinforced Concrete Slab of Arbitrary Geometry
Authors: Efimenko E. A.
Published: May 2024

Introduction. A number of research held in recent years on rational design of buildings and structures built for different purposes study the rational position of the vertical members — columns or supports. However, the majority of up-to-date research and publications focus on elucidating the rational position of the supports in the context of improving the efficiency of the beams. Whereas the behaviour of the reinforced concrete slabs affected by changing the position of the supports is not covered well enough in the modern research. The present study is targeted exactly at revealing the behaviour of the reinforced concrete slab structures of a building in case of varying position of the main supports.

Materials and methods. During the present numerical experiment, a reinforced concrete slab of arbitrary geometry with the given thickness h, the concrete grade with the respective properties and the reinforcement possessing the properties according to its class, has been investigated. Additionally, it was decided to set the distance magnitudes from the centers of gravity of the upper and lower row of reinforcement to the bottom and top surface of the slab 𝑎𝑥, 𝑎′𝑥, 𝑎𝑦, 𝑎′𝑦. The number of columns n was set for the slab. It was considered that the number of columns was known, but their position could change. Moreover, among the total number of columns, there were distinguished the certain ones having the definite (constant) position, whereas the remaining supports could change their position within the slab area. Bearing in mind the above, the researchers were to solve the problem of rational position of the moveable columns.

Results. This paper presents the results of the numerical experiment on identifying the most optimal (rational) position of the reinforced concrete columns supporting a slab of the arbitrary geometry. Based on the several parameters at once, such as deflection, potential strain energy and consumption of the reinforcement products, the analysis of the rational position of the supports under the slab was made and functional dependences on changing the above mentioned parameters have been presented in the work.

Discussion and conclusion. Based on the results obtained in the numerical experiment, the analysis of the behaviour of the reinforced concrete slabs of a set thickness upon changing the position of the supports under the slab was made and the changes of the slab operational parameters were analysed and compiled into the functional dependences.
Determining the Most Efficient Method of Strengthening the Reinforced Concrete Columns under Different Loading Levels
Authors: Georgiev S. V. , Mailyan D. R. , Solovyeva A. I.
Published: May 2024

Introduction. The method of strengthening the reinforced concrete structures is chosen depending mainly on the cost and timeframe of the performed work. In each specific case, the decision is made depending on the load, type of defects, operational features, etc. Apart from the direct costs of inspection, strengthening project design, materials, lifting and transport services and the cost of strengthening works proper, there is a number of additional costs related to the technological features of the work performed. Among the new methods of strengthening, the method of external strengthening with the composite carbon materials can be particularly emphasised. Compared to the previously developed methods of strengthening with the reinforced concrete and metal, the composite systems are easily transportable and do not incur additional costs. The aim of this study is to determine the method of strengthening most rational for the compressed structures.

Materials and methods. The authors have examined three methods of strengthening the compressed reinforced concrete structures. In the frame of the research a numerical experiment has been carried out, in which a reinforced concrete column was strengthened at different strengthening coefficients from 1.1 to 2.0, i.e., from 10 to 100% of strength increase. The estimations of the cost of strengthening the column by three methods of strengthening have been carried out: jacketing using the reinforced concrete, metal and composite materials. After carrying out thirty variants of calculation, a table presenting all specifications and quantities of the materials has been drawn up. At the final stage of the research, the total cost of each method under investigation has been estimated based on the prices of the selling companies.

Results. The analysis of strengthening with the reinforced concrete revealed that at most of the strengthening coefficients the achieved structural reinforcement is minimal. Under the high loading levels strengthening with the metal is not economically expedient, as it implies the use of the large-section angles.  The composite material systems of external strengthening are very material-consuming at all load increasing coefficients. Taking into account the high cost of materials, this method is basically the least economically expedient.

Discussion and conclusion. Based on the results obtained, the efficiency of three most common methods of strengthening the reinforced concrete compressed columns was analysed. Proposals on the rational design of the strengthening systems for the eccentrically compressed reinforced concrete poles under the different eccentricities of load applied have been developed.

The mathematical abilities of second-grade elementary school students in the multiplication operation material are still relatively low. Seeing this condition, teachers must pay attention to teaching students variations in the use of learning media that invite students to play while learning so that teachers can instil the mindset that multiplication is very easy. One learning media that can be used is the multiplication wheel learning media. This research aims to describe the design of multiplication wheel learning media on number multiplication material. This research is library research. Using the multiplication wheel learning media in Mathematics subjects in class II SD/MI can improve student learning outcomes because learning activities are carried out by playing while thinking. With learning media like this, students will not get bored and bored when participating in learning activities. The multiplication wheel learning media is also very easy for lower-grade students to use. This multiplication wheel learning media is three-dimensional. Because the media does not move and does not make sound, in learning mathematics, especially in improving material, the teacher must be able to instil the mindset that addiction is very easy. Using the learning media of the accretion wheel in Mathematics in class II SD/MI can improve student learning outcomes because learning activities are carried out by playing while thinking. The existence of learning media like this will make students not bored and not bored in participating in learning activities. Improved learning media is now also very easy for low-grade students to use. This accretion wheel learning media includes three-dimensional learning media because the media does not move on its own and does not make sound.

Tratamiento de la moneda extranjera en economías de tipo de cambio múltiple
Authors: Gilabert Manuel
Published: May 2024

La contabilidad ha sido una herramienta clave en la toma de decisiones empresariales y en la evaluación de la salud financiera de las organizaciones. En el contexto económico argentino, la brecha cambiaria, es decir, la diferencia entre los tipos de cambio oficial y los del mercado paralelo, ha tenido un impacto significativo en la economía del país y plantea desafíos importantes para la contabilidad.
Este estudio se enfoca en analizar si la contabilidad puede reflejar adecuadamente la realidad económica de las empresas en Argentina, considerando las regulaciones cambiantes y las diversas tasas de cambio, como el Tipo de Cambio Oficial, Dólar Solidario, Dólar Bolsa, Dólar CCL, entre otros. La brecha cambiaria ha generado una discrepancia entre estas cotizaciones, lo que complica la valuación de activos, pasivos y operaciones en moneda extranjera. El trabajo también explora el acceso al dólar por parte de las empresas argentinas, detallando las restricciones y regulaciones vigentes en el mercado cambiario.
La investigación utiliza una metodología cualitativa que incluye la recopilación documental de normativas y publicaciones, así como la observación de situaciones empresariales reales. A través de un análisis de los estándares contables y la doctrina se identifican ajustes necesarios en la práctica contable, como, por ejemplo, la utilización de tipos de cambio distintos al oficial en determinadas situaciones.

La revisión de la literatura es limitada al respecto y por ello es necesario indagar sobre este tema. El objetivo del estudio es establecer la eficacia de la docencia compartida en los procesos de enseñanza-aprendizaje, específicamente, en este artículo, se identifican las características del profesorado codocente. La investigación analiza, a través de una metodología cualitativa de tipo exploratorio, la experiencia de maestros y equipos directivos de dos centros de primaria de la provincia de Barcelona, contrastándola con la opinión de dos expertas en docencia compartida. Los resultados presentan un compendio de diez características docentes que se deben considerar en el momento de utilizar la codocencia. Las conclusiones señalan que es conveniente contar con un perfil de profesorado adecuado e intentar establecer parejas compatibles, puesto que de esto depende, ampliamente, el éxito de la experiencia. El estudio pretende ser una orientación para el profesorado que quiera iniciarse en esta metodología y para los equipos directivos que deban gestionar su organización en los centros educativos

La enseñanza de la lengua española tiene gran desarrollo en China. Sin embargo, los estudiantes universitarios tienen problemas de aprendizaje en lectura. Este estudio analiza los comportamientos estratégicos en el aprendizaje de la lectura de estudiantes de la carrera de Español de la Universidad de Linyi. La muestra se conformó con grupos de alto y bajo rendimiento académico en lectura. Se aplicó una prueba pedagógica y un cuestionario de autorreporte estratégico. Se utilizó el SPSS versión 26.0, la prueba T y la correlación Pearson para analizar los datos. Se encontró que, a mayor frecuencia de uso de estrategias de aprendizaje en los dominios cognitivo, motivacional y afectivo, mejor rendimiento académico en la lectura. También se determinaron las estrategias de aprendizaje estadísticamente significativas empleadas por los estudiantes del grupo de alto rendimiento. Estos resultados pueden considerarse en estudios sobre la enseñanza estratégica de la lectura en español como lengua extranjera.

The diagnostic approach for patients with tremor is challenging due to the complex and overlapping phenotypes among tremor syndromes. The first step in the evaluation of tremor is to identify the tremulous movement and exclude the tremor mimics. The second step is to classify the tremor syndrome based on the characteristics of tremor from historical clues and focused examination (Axis 1). Comprehensive tremor examinations involve the assessment of tremor in different conditions (rest, action or mixed, position or task-specific), distribution of tremor (upper limb, lower limb, head, jaw), positive signs for functional tremor (FT) if suspected (distractibility, entrainment, co-contraction), and associated neurological signs including parkinsonism, dystonic posture, cerebellar/brainstem signs, neuropathy, and cognitive impairment. A pivotal feature in this step is to determine any distinct feature of a specific isolated or combined tremor syndrome. In this review, we propose an algorithm to assess upper limb tremors. Ancillary testing should be performed if clinical evaluation is unclear. The choice of investigation depends on the types of tremors considered to narrow down the spectrum of etiology (Axis 2). Laboratory blood tests are considered for acute onset and acute worsening of tremors, while structural neuroimaging is indicated in unilateral tremors with acute onset, nonclassical presentations, and a combination of neurological symptoms. Neurophysiological study is an important tool that aids in distinguishing between tremor and myoclonus, etiology of tremor and document specific signs of FT. Treatment is mainly symptomatic based depending on the etiology of the tremor and the patient’s disabilities.
Elevated level of neuroserpin is an indication for the resistance to gambogic acid-induced apoptosis and oxidative stress in triple-negative breast cancer cells

Published: May 2024

Background

The triple-negative breast cancer (TNBC) subtype, characterized by loss of HER2, estrogen, and progesterone receptors, displays aggressive phenotype and poor prognosis compared to other BC subtypes. Since the TNBC cells are devoid of receptors, endocrine therapy is an ineffective option for TNBC patients, necessitating canonical chemotherapy strategies to treat TNBC. It is crucial to use alternative and natural agents to support chemotherapy in TNBC.

Objectives

To clarify the molecular mechanism of the tumorigenic effects of gambogic acid (GA) on TNBC cells with different epithelial character since GA has a wide spectrum of anticancer activity for most cancer types.

Methods

We determined the cytotoxic dose of GA incubation of TNBC cells (MDA-MB-231 and BT-20 cells) for 24 h. We performed the MTT test and toluidine blue (TB) staining protocol for TNBC cells. We analyzed E-cadherin, N-cadherin, Bax, and neuroserpin mRNAs in both cells by qPCR. We evaluated apoptosis using DAPI staining and assessed the ROS using the 2ʹ,7ʹ-dichlorofluorescin diacetate (DCFH-DA) method.

Results

We determined the IC50 concentrations of GA in MDA-MB-231 and BT-20 cells to be 315.8 nM and 441.8 nM, respectively. TB staining showed that BT-20 cells survive at excessive cytotoxic doses of GA, while most of the MDA-MB-231 cells were killed. Also, we found that BT-20 cells are more resistant to GA-induced apoptosis and oxidative stress than the MDA-MB-231 cells. qPCR results showed that GA upregulated neuroserpin, an oxidative stress-relieving factor in the BT-20 cells, but not in the MDA-MB-231 cells.

Conclusions

The elevated level of neuroserpin could be a predictive marker to determine the development of resistance to chemotherapeutic agents.
Optimal final adult height achieved by low-dose recombinant human growth hormone therapy

Published: May 2024

Background

Thailand has been administering the recombinant human growth hormone (rhGH) treatment for >20 years. Due to limited resources being available, efforts have been directed toward utilizing rhGH at the lowest feasible dose. However, there is currently a lack of evidence in terms of the efficacy and outcomes.

Objective

To evaluate the auxological outcomes of growth hormone (GH) treatment and the GH secretion ability after reaching final adult height (FAH) and discontinuing rhGH.

Methods

Data of 40 patients were retrospectively reviewed. The clinical characteristics, auxological data, and results of biochemical and endocrine investigations before and during rhGH treatment were evaluated. In addition, GH retesting was performed in 24 patients using the insulin tolerance test.

Results

Twenty patients (50%) had complete growth hormone deficiency (GHD), defined as peak stimulated GH level <5 ng/mL, and the remaining patients had partial GHD. Most patients were male (n = 25, 62.5%). The mean age at which rhGH was initiated was 8.9 years. Patients with partial GHD received a higher dose of rhGH than those with complete GHD (30.9 µg/kg/d vs. 26.2 µg/kg/d, P = 0.02). Patients with complete and partial GHD reached FAH at height standard deviation scores (SDSs) of −0.65 and −1.47, respectively. The factors associated with obtaining a good clinical response in terms of height gain included peak-stimulated GH level, age of puberty, and age of discontinuing rhGH. After completing the rhGH treatment, 13 of the 24 patients showed normal GH secretion. Patients with multiple pituitary hormone deficiency (MPHD) were likely to have persistent GHD through adulthood (n = 8, 88.9%).

Conclusion

This study has demonstrated that the use of low-dose rhGH could result in healthy populations achieving optimal FAHs. Patients with MPHD might not require retesting as they were likely to have persistent GHD. The results obtained in this research highlight the benefits of the treatment. This treatment can be applied in resource-limited countries.

Published: May 2024

Background

Wolffian tumors in females are rare gynecological neoplasms, with fewer than 100 cases reported. Existing literature primarily focuses on the pathology, and reports involving imaging are limited.

Objective

This study presents a case of Wolffian tumor, emphasizing its magnetic resonance imaging (MRI) characteristics to enhance preoperative diagnostic accuracy.

Case report

A 56-year-old woman presented with a year-long history of irregular vaginal bleeding. MRI revealed a solid mass in the right adnexal region. On T2-weighted images, the mass exhibited slightly elevated signal intensity with a distinctive low-signal intensity rim. Diffusion-weighted imaging displayed markedly increased signal intensity, and the contrast enhancement was moderate. The patient underwent laparoscopic right adnexectomy and received a Wolffian tumor diagnosis. No recurrence was observed during a 6-month follow-up.

Conclusions

Wolffian tumors exhibit distinctive MRI presentations. Notably, the prominent low-signal intensity rim on MRI may aid in accurate preoperative tumor diagnosis.
