Published: February 2025

ABSTRACTThe rapid electrification across transportation sectors has promoted extensive adoption of electrical power systems. Power electronic converters play a crucial role as components within these systems, enabling efficient and stable system operation through sophisticated control strategies. However, traditional approaches to power converter control often cannot deliver the rapid response and robust control capability in handling nonlinear systems needed in these applications. With the rapid advancement of computational capabilities and various simulation technologies, advanced information technologies such as Artificial Intelligence (AI) and Digital Twin (DT) can significantly enhance control performance by leveraging powerful algorithms and high‐fidelity models. AI and DT have been proven to be efficient and reliable tools in addressing these challenges. This review critically examines the application of AI and DT technologies in power converter control for electrical power systems on transportation platforms, analyzing DT models from the perspective of AI algorithms and offering insights for their deeper integration. Finally, the review identifies ongoing challenges and future trends in this field, providing valuable resources for researchers and practitioners involved in developing power converter control of onboard electrical power systems.
Dual‐mode control and switching control strategy of microgrid for power battery formation and grading testing system

Published: February 2025

AbstractTo address the stability issues of the microgrid system for power battery formation and grading testing systems in scenarios involving multiple parallel converters, this paper proposes a hybrid dual‐mode control strategy combining grid‐following and grid‐forming modes to ensure stable operation of the microgrid system. However, the conventional switching between the two control strategies during the operation of the converter can lead to transient power and current surges, which may even affect the stable operation of the converter. Therefore, this paper studies the characteristics of grid‐following and grid‐forming control strategies. Based on the fact that both have the same type of output variables, a seamless switching control strategy based on the method of controller output state following is proposed, the switching time can be shortened by more than 1 s to the greatest extent possible. Furthermore, a seamless switching control strategy for grid‐connected and islanded operation modes of the microgrid system is introduced. Finally, the effectiveness of the proposed method is verified using the Simulink simulation platform and a hardware‐in‐the‐loop experimental simulation platform. The experimental results demonstrate the validity of the proposed approach.
Les consommateurs : frein ou levier pour le développement d’une filière ovine en zone contaminée par le chlordécone en Guadeloupe ?
Authors: Nabajoth Cyndi , Lakhia Steewy 
Published: February 2025

En Guadeloupe, un tiers des sols a été durablement contaminé par un pesticide organochloré, le chlordécone, suite à son utilisation contre le charançon noir du bananier (Cosmopolite sordidus) jusqu’au début des années 1990. Cette contamination des sols a en retour impacté différents maillons de la chaîne alimentaire et notamment les animaux d’élevage qui se contaminent en ingérant des particules de sol ou du fourrage contaminé lors du pâturage, mais aussi en ingérant de l’eau contaminée ; ils ne sont alors plus commercialisables si la limite maximale de résidu en chlordécone est atteinte. Les possibilités de diversification des systèmes de production via l’élevage ou plus récemment de contrôle de l’enherbement par les ovins, notamment dans les bananeraies, sont alors fortement contraintes. Des travaux ont démontré qu’il était possible de décontaminer les animaux via une production hors sol. Mais la perception du consommateur vis-à-vis de cette viande issue de la décontamination reste inconnue et soulève la question de l’acceptation dans le cas où ce type de filière viendrait à se développer. Pour répondre à cette problématique, un questionnaire auprès de 309 consommateurs a été réalisé. Les résultats montrent que les consommateurs seraient prêts à consommer une viande ovine décontaminée, mais qu’il existe une défiance vis à vis des structures en charge du contrôle à l’abattoir.
Wilhelm Conrad Röntgen’s Strasbourg Years (1872–1879): W.C. Röntgen – Two Decades before the Discovery of X-rays (with GPX Track “Röntgen in Strasbourg”)
Authors: Rabe Jan , Busch Uwe , Michels Marcel , Schlemmer Heinz-Peter 
Published: February 2025

AbstractTwo decades before his groundbreaking discovery of X-rays in 1895, Wilhelm Conrad Röntgen worked from 1872–1879 as an assistant, private lecturer, and finally associate professor at the University of Strasbourg, which was then part of the German Empire. This period was briefly interrupted in 1875/76 by Röntgen’s first professorship at the Agricultural Academy in Hohenheim.Based on publications about W. C. Röntgen and research in a total of seven archives (Strasbourg, Hohenheim, Remscheid-Lennep, Würzburg), this work describes his professional career and private life during this period.In addition to his workplaces, a total of seven places of residence were identified for this period, four of which are described for the first time. A GPX track leading past the Strasbourg addresses is available for download. Archival material documenting his career during this period has been compiled. All of Röntgen’s publications from this period are also listed. A detailed exchange of letters between Bertha Röntgen and a friend provides an insight into the Röntgen couple’s private life.This early period in W. C. Röntgen’s career forms the basis for his successful career with three subsequent full professorships, including his discovery of X-rays in 1895.

Published: February 2025

AbstractVisceral artery aneurysms (VAA) are rare, and data on their occurrence and treatment are often outdated or heterogeneous. The objective of this study is to provide a comprehensive overview of features and interventional treatment options for VAA.We analyzed demographic, procedural, and clinical data on VAA from 2018 to 2022 based on data derived from the German Society for Interventional Radiology and Minimally Invasive Therapy (DeGIR) registry regarding demographic details, aneurysm characteristics, treatment processes, and outcomes such as technical success, complication rates, and radiation exposure. Group comparisons between aneurysm locations and types were calculated as dependent variables as well as occurrence of incomplete embolization, complication rates, technical success, duration of intervention, and dose-area-product (DAP).In total 647 patients were enrolled. The mean age was 66 years, with 68.5% male. The most affected arteries were splenic (27.5%) and renal (21.3%). True aneurysms were most common (56.7%). Technical success was 91.2%, while primary incomplete embolization occurred in 47.3%. Complications were observed in 4.8%, with a 0.2% mortality. Mean intervention duration was 67 min, mean fluoroscopic time was 36 min and mean DAP was 9560 cGycm2. There were no significant differences in primary incomplete embolization, complication rate, correct placement of embolization material, duration, and DAP based on aneurysm location. Aneurysm types showed a significant difference in incomplete embolization, with dissections having the highest rates and longest durations of intervention and highest DAP.The analysis of DeGIR quality management data reveals consistently high technical success and low complication rates in endovascular treatment of VAA. Dissecting aneurysms exhibit the highest rates in incomplete embolization, requiring the longest interventions and increased radiation. Enhancing the DeGIR registry with follow-up features would benefit assessing VAA occlusion rates. The data provide a comprehensive nationwide overview of how interventional radiology can impact treatment strategy.

Published: February 2025

ZusammenfassungDie Multiple Sklerose ist eine Erkrankung des zentralen Nervensystems, die sich in der gestörten Reizweiterleitung durch Schädigung der Myelinschicht widerspiegelt. Neben den visuell evozierten Potenzialen sind es immer mehr auch die vestibulär evozierten myogenen Potenziale (VEMPs), die zur Befundung mitbetrachtet werden. Aufgrund eines geringen Signal-Rausch-Abstandes werden üblicherweise einige 100 Reizantworten gemittelt, um aus diesen Kurven Amplitudenhöhe und Latenzen zu bestimmen. Dieses Verfahren filtert jedoch Informationen aus der Messung heraus, welche weitere Erkenntnisse über den Krankheitszustand liefern könnten.16 junge Patienten mit MS und einem EDSS-Score von 1,4±0,6 wurden mit 92 gesunden Probanden gleichen Alters verglichen. Als Parameter wurden aus den taktil ausgelösten oVEMPs die n10-Amplitude, die n10-Latenz, das AR sowie 5 neue Parameter aus der neuen Analysemethode herangezogen.Die n10-Amplitude gesamt sowie die n10-Amplitude links waren grenzwertig signifikant unterschiedlich. Demgegenüber waren die n10-Amplitude rechts und der LSD-Parameter nicht signifikant unterschiedlich. Alle n10-Latenzen und das AR sowie alle Parameter aus der neuen Analyse waren signifikant unterschiedlich zwischen den Gruppen.Die vorliegende Studie bestätigt die zum einen schon bekannten Veränderungen in der Registrierung von oVEMPs bei Patienten mit MS gegenüber gesunden Probanden, und zum anderen haben die neuen Parameter das Potenzial, den aktuellen Krankheitszustand besser zu beschreiben und detaillierte Informationen über den aktuellen Zustand der Myelinisierung bzw. die Lokalisierung der pathophysiologischen Prozesse im ZNS zu geben.
Knee angle reproduction tests: influences of body orientation,
movement direction and limb dominance

Published: February 2025

AbstractApplying joint position sense tests under different test conditions may introduce
reproduction error bias, which can result in different therapeutic consequences.
This study investigated the effects of body orientation, movement direction, and
limb dominance on the active knee angle reproduction error. Subjects underwent
active contralateral knee angle reproduction tests in a seated versus prone
position, from a starting point of knee flexion versus knee extension, and with
the dominant versus nondominant limb setting the target angle. The test order
was randomly determined for each subject. The primary outcome was the absolute
active knee angle reproduction error (°). The data of 54 healthy subjects
(mean±standard deviation, age: 26±5 years, height: 174±11 cm, body mass:
69.9±14.4 kg, and Tegner activity score: 5.8±1.9) showed that the reproduction
error was greater in the seated position than in the prone position. The use of
the dominant limb as the reference limb was associated with significantly
greater errors in the seated position, but not in the prone position. In
conclusion, directly comparing the results obtained in the prone and seated
positions is not recommended. However, the dominance of the reference limb might
be relevant when testing patients and comparing healthy and injured knees.
Homeopathic Management of Residual Paralysis as a Sequel to Bell's Palsy: Experience from Two Case Reports
Authors: Archana Archana , Gupta Ekta , Varanasi Roja 
Published: February 2025

AbstractBell's palsy is a peripheral facial nerve palsy of unknown etiology and is the most common cause of one-sided facial nerve palsy (70%). Although this condition is self-limiting, long-term effects are also reported. Reversibility of nerve function depends on the health of both the facial nerve (if intact) and the facial muscles. We present here two cases of Bell's palsy graded III and II on the House–Brackmann facial nerve grading system treated with individualized homeopathic medicine with substantial improvement. Homeopathic medicines Sepia and Lachesis were used to treat these cases in a personalized and tailored manner as per the homeopathic principles. Possible causal attribution of changes was assessed by the modified Naranjo criteria. The case report is valuable to the profession for providing evidence of the successful treatment of neurological disorders such as facial nerve palsy.
Percutaneous Transesophageal Gastrostomy
Authors: Hufnagle John , Fish Adam , Masi Athena , Lee Jessica 
Published: February 2025

AbstractGastrostomy tube placement is a well-established technique for providing long-term feeding or decompression to patients with dysphagia or the need for gastric venting. However, direct transabdominal access to the stomach is not feasible in some patients, such as those without a safe percutaneous route to the stomach, with conditions that may inhibit tract healing, and/or at high risk of peritonitis. For these patients, percutaneous transesophageal gastrostomy (PTEG) is a safe and effective technique for providing gastric access for enteral feeding or decompression. PTEG placement involves ultrasound-guided percutaneous access to the cervical esophagus using a fluid-filled balloon as a target. Since the peritoneum is not breached during PTEG placement, the risks of peritoneal spillage of enteric contents and intra-abdominal hemorrhage are avoided. However, placement requires a safe esophagostomy window and has contraindications and complications distinct from direct transabdominal access. Here, we describe the approach to patient workup and PTEG placement, present a few special situations that can be encountered, and discuss existing data regarding patient outcomes.

Published: February 2025

AbstractLeiomyosarcoma (LMS) is an uncommon malignant spindle cell neoplasm of smooth muscles, accounting approximately 7% of soft tissue sarcoma. Primary LMS involving bone is an exceptional entity with very few cases described in the literature. The clinical, imaging, and pathological findings were analyzed retrospectively in three confirmed cases of primary LMS of bone. Pain and swelling were the patients' clinical symptoms. On imaging, LMS was often described as a solitary ill-defined lytic lesion with cortical breach depicted on radiograph or computed tomography (CT) scan. Magnetic resonance imaging (MRI) reveals a heterogeneous intermediate-hyperintense signal lesion on T2-weighted imaging (T2WI) with postcontrast enhancement. Histopathology reveals spindle cells arranged in fascicles with nuclear atypia and smooth muscle actin (SMA) positivity on immunohistochemistry (IHC)—consistent with diagnosis of LMS. The patients underwent surgical gross total resection with curative intent, followed by adjuvant chemotherapy or radiotherapy depending upon the stage and histological grade of LMS. On follow-up, the patients were disease free with no evidence of recurrence.

Abstract
Introduction Pathogenic germline mutations in BRCA (gBRCAm) genes can heighten the risk of breast cancer (BC) among carriers. Economic constraints and patient testing hesitancy challenge adherence to hereditary germline testing guidelines. As a result, clinicians prioritize hereditary BC screening based on patient willingness, affordability, and therapeutic benefit.
Objectives The objectives of the study were (1) to identify the pattern of hereditary cancer germline testing among women diagnosed with BC and (2) to determine the prevalence of gBRCAm among the women with BC who underwent hereditary cancer germline testing.
Materials and Methods A retrospective study was conducted at a cancer hospital between October 2023 and January 2024. We aimed to assess the germline testing patterns of physicians in our hospital by examining the clinical profile of patients with BC who underwent hereditary cancer multigene (30 gene panel) mutation testing using next-generation sequencing between January 2021 and December 2023. A simultaneous analysis was performed with a multiplex ligation-dependent probe amplification to detect deletions and duplications in the BRCA1 and BRCA2 genes. The classification of the variants as pathogenic and variants of uncertain significance (VUS) was determined by the American College of Medical Genetics and Genomics guideline.
Results Of the 3,600 patients with BC during this study period, only 325 (9%) underwent germline testing. The testing patterns indicated that the median age of those tested was 48.4 years (standard deviation [SD]: 10.1; range: 20–77), 189 patients (58.2%) were younger than 50 years, and 103 patients (31.7%) had a family history of cancer. Family history of BC was reported in 95 (29.2%) patients. Bilateral BC was noted in 19 patients (5.8%), while ovarian cancer was reported in 9 (2.8%) patients. Triple-negative BC (TNBC), hormone receptor–positive BC, and HER2-positive BC were reported in 52, 42.8, and 17.2% patients, respectively. Pathogenic/likely pathogenic (P/LP) germline BRCA mutations were detected in 48 (14.7%) patients (BRCA1 in 29/325 [8.9%] patients and BRCA2 in 19/325 [5.8%] patients). The highest prevalence was seen among TNBC (36/169, 21.3%) patients. P/LP gBRCAm prevalence among those with and without notable family history was 27/103 (26.2%) and 21/222 (9.5%), respectively; age less than 50 years and greater than 51 years was noted in 32/189 patients (16.9%) and 16/136 (11.8%) patients, respectively. VUS was noted in 29 patients (BRCA1 in 4 patients [8.9%] and BRCA2 in 25 patients).
Conclusions Measures to ensure equitable access to genetic testing can improve testing rates and enhance patient outcomes through personalized care.

Authors: Sreenath Nihanthy D. , Kushwaha Naveen Kumar , R. Kaushik M. , Govind Rajath 
Published: February 2025

Abstract
Background In India, around 55,000 patients are on dialysis, with a 10–20% annual increase. With the growing dialysis population in India, cancer risk among end-stage renal disease (ESRD) patients is increasing. Managing chemotherapy in these patients is challenging due to limited data and guidelines, leading to treatment uncertainty.
Objectives This study provides real-world data from India on the clinical management and outcomes of cancer patients with ESRD undergoing dialysis while receiving chemotherapy.
Material and Methods This prospective study analyzed data from five cancer patients with end-stage renal disease (ESRD) on hemodialysis prior to diagnosis of cancer treated at a tertiary oncology center in India. We analyzed the demographic details, cancer staging, treatment regimens, and dosage adjustments. Treatment modifications due to renal dysfunction, toxicities, and patient outcomes were also reviewed over a 12-month follow-up.
Results The cohort consisted of 80% (4/5 pts) females, with a median age of 57.8 years. Hypertensive and diabetic nephropathy were the leading causes of ESRD. Cancers included breast (3/5 pts), lung (1/5 pts), and ovarian (1/5 pts), with varying stages of diagnosis. 80% (4/5) of patients required tailored drug management. The Ovarian cancer patient experienced severe hypersensitivity to carboplatin, which was managed conservatively. No grade 3/4 immune-related adverse events occurred, and all patients were alive and disease-free at the one-year follow-up.
Conclusion Carefully tailored treatment strategies and a coordinated multidisciplinary approach allowed positive outcomes for cancer patients on dialysis, emphasizing the need for personalized approaches. These findings highlight the importance of refining treatment protocols for this complex group.
Diuretic Renography in a Sitting Position with F + 10(sp) Method for Diagnostic Management of Primary Megaureter in Adults

Published: February 2025

Abstract
Objective Primary megaureter is a disease defined as the dilatation of the ureter caused by a congenital abnormality of the lower ureteral tract. Adult patients with primary megaureters typically present with no symptoms, making conservative management the preferred treatment. However, if an obstruction is present, we recommend ureteral reimplantation. The major diagnostic challenge is to distinguish which patients need surgical intervention. Ultrasound, computed tomography, and magnetic resonance imaging urogram findings of obstruction may be misleading because they are based on morphological aspects, and persistence of contrast in the upper urinary tract is not specific for obstruction. Renal scintigraphy is the key test for choosing surgical or conservative treatment; historically, the criterion for surgical treatment is the decrease of split renal function (SRF) less than 40%. Unfortunately, SRF might be only an indirect finding of obstruction; otherwise, the 20-minute/peak ratio may offer urologists an earlier, direct, and reliable index of urine outflow in monitoring ureteral flow. This study suggests that the F + 10(sitting position) test, which measures diuretic renography (DR) in a sitting position, is a new and useful way to find out how well primary megaureters are working for diagnosing and treating them. It focuses on the 20-minute/peak ratio that can be found when gravity is favorable.
Methods Twenty-eight adult patients (15 males, 13 females) affected by primary megaureter were retrospectively enrolled. Twenty-six patients had unilateral megaureter, and 2 patients had bilateral megaureter, for a total of 30 megaureters radiologically confirmed (16 left, 14 right). In total, we performed twenty-eight 99mTc-mercaptoacetyltriglycine DR in a sitting position using the F + 10 (sitting position) method. In our series, 17 patients received conservative treatment, and 11 patients underwent ureteral reimplantation.
Results Based on the 20-minute/peak ratio values, 17 out of 30 megaureters were diagnosed as obstructed. A discordance between SRF and 20-minute/peak ratio findings has been seen. No side effects were seen.
Conclusion A decrease in SRF is an indirect and late index of obstruction. Twenty-minute/peak ratio measured by DR in sitting position may improve the sensitivity and accuracy of the test for diagnosis of obstructive megaureters.
