Complete encasement of the radial nerve by a giant lipoma: illustrative case
Authors: Bah Eugene S , Barone Damiano G , Spinner Robert J 
Published: July 2024

BACKGROUND
Among the spectrum of adipose lesions associated with peripheral nerves, complete circumferential encasement of the nerve by the lesion is a very rare entity. The authors report the first case of a giant lipoma that completely and circumferentially encased the radial nerve.

OBSERVATIONS
A 57-year-old woman presented with a large left-arm mass that she had noticed over a year following significant weight loss. She had hypersensitivity and dysesthesias in the left posterior arm but no weakness or other symptoms. Magnetic resonance imaging of the left upper limb demonstrated a large lipoma completely encasing the radial nerve, originating at the level of the spiral grove proximally and extending distally to the lateral epicondyle. The lesion was completely resected at surgery with total preservation of radial nerve function.

LESSONS
Lipomas encasing peripheral nerves can be difficult to manage while preserving function. This case adds to the intriguing spectrum of adipose lesions associated with peripheral nerves.

Authors: Takahashi Toshihide , Yanaka Kiyoyuki , Aiyama Hitoshi , Saura Minami , Kajita Michihide , Takahashi Nobuyuki , Onuma Kuniyuki , Ishikawa Eiichi 
Published: July 2024

BACKGROUND
Neurenteric cysts are relatively rare benign congenital intracranial cystic lesions that enlarge rarely and very slowly. The authors present a case of an enlarging neurenteric cyst at the craniocervical junction with a fluid-fluid level on magnetic resonance imaging (MRI).

OBSERVATIONS
A 34-year-old man with no significant medical history underwent head MRI to investigate mild headaches. An incidental cystic lesion, approximately 8 mm in diameter, was revealed at the craniocervical junction. Serial follow-up MRI showed cyst enlargement with a fluid-fluid level. Four years later, the cyst reached a size of 15 mm and was surgically removed. The cyst contained cloudy fluid with a high protein concentration, without any bleeding or tissue fragments. Pathological examination confirmed the diagnosis of a neurenteric cyst. The patient recovered well, was discharged home, and has remained recurrence free for 2 years.

LESSONS
The growth dynamics of the relatively rapidly expanding neurenteric cyst at the craniocervical junction were monitored over time using MRI. This cyst exhibited the distinctive feature of a fluid-fluid level as it enlarged. Investigating the mechanisms underlying fluid-fluid level formation may offer novel insights into the pathogenesis of cyst enlargement.

Pituitary germinoma after resection of a mature third ventricular teratoma: illustrative case
Authors: Hallenberger Tim J , von Seth Emma , Roethlisberger Michel , Guzman Raphael , Soleman Jehuda 
Published: July 2024

BACKGROUND
Metachronous intracranial germ cell tumors (iGCTs)—unrelated, histologically different iGCTs occurring at different time points—occurring within the same patient remain a rarity. Herein, the authors report such a case and discuss the literature and potential pathophysiological mechanisms leading to this phenomenon.

OBSERVATIONS
A 9-year-old boy presented with new-onset impaired balance, headaches, nausea, visual disturbances, and left facial paresis. Magnetic resonance imaging (MRI) scans revealed a suspected pineal region teratoma originating from the pineal gland with consecutive obstructive hydrocephalus. A mature teratoma was diagnosed and resected. Postoperative recovery was good, and the patient could return to his normal daily activities. However, a new, slowly progressive lesion in the sellar region with an enlarged infundibular stalk was detected on follow-up MRI 3.5 years after initial pineal region teratoma resection. Biopsy revealed a newly developed pure germinoma. The patient was treated with radiotherapy plus chemotherapy and remained relapse free at the last follow-up. Sixteen other cases have reported a surgically resected primary mature teratoma, wherein patients developed metachronous germinomas during follow-up. Different theories try to elaborate this phenomenon, yet none can completely account for it.

LESSONS
Although rare, metachronous iGCT is a phenomenon neurosurgeons should be aware of. In patients treated for iGCT, close long-term clinical, imaging, and laboratory follow-up is recommended.

A Stylistic Analysis of ‘Two Friends’ Short Story by Guy de Maupassant In terms of Halliday’s Systemic Functional Grammar Author: Asst. Lecturer: Shouq Ali Afrawi
Authors: Afrawi Asst. Lecturer: Shouq Ali 
Published: July 2024

In this study, a stylistic analysis is conducted to ‘Two Friends’ short story by Guy de Maupassant in terms of M. A. K. Halliday’s systemic functional grammar theory. Halliday believes that grammar is functional because it is designed to account for how the language is used. He assumed that there are two very general purposes underlying all uses of language; to understand the environment (ideational) and to act on the others in it (interpersonal). Combined with these purposes, Halliday added a third component (textual), which is relevant to the other two.
This stylistic analysis is conducted on three main levels; grammatical, phonological and lexical. At the end, one may have a clear picture of the literary work and it would be an objective way through which we can have a new interpretation of the short story.
Key words: Stylistics, Systemic Functional Grammar, Guy de Maupassant, Two Friends.
A Stylistic Analysis of Joe Biden's Inaugural Political Speech
Authors: Saza Ahmed Fakhry Abdulla  
Published: July 2024

In this paper, a stylistic approach has been used to investigate the linguistic features of President Joe Biden's inauguration political speech. Special importance is given to its linguistic characteristics that affect the structure of the selected political speech. This paper is an attempt to highlight the political language of Biden’s political speech. The aim is to seek out how political speeches are packaged to persuade citizens and readers and how stylistic analytical tools assist readers in interpreting the language of Biden in the selected speech. The data has been collected from Time Magazine. The data selection is restricted to Biden's inauguration political speech and has been chosen based on certain foregrounding features that indicate a powerful stylistic effect on readers. The qualitative method has been used to analyze the selected data. In the analysis, some linguistic features, such as graphological, syntactic, grammatical deviations, transitivity, and modality have been used to investigate the style of the selected speech to reveal persuasion. The findings show that Biden's inauguration political speech achieves power, and persuasion through the use of certain stylistic features including lexical and grammatical categories such as abstract nouns, personal pronouns, mental processes, and certain modal auxiliaries. It is concluded that the lexical items that Biden uses are crucial in passing his message to his nation. However, the tendency to use distinctive foregrounding features in the consistent repetition of lexical items and sentence structures are stylistic technique used by Biden for the sake of persuasion.

Published: July 2024

Introducción: La violencia sexual es uno de los problemas más graves de salud pública, de justicia social, derechos humanos, sexuales y reproductivos en América Latina; se la define como la realización de todo acto sexual sin consentimiento ni deseo por parte de la víctima, implica el uso de la fuerza y produce graves consecuencias físicas, psicológicas y sociales. Por aquello se vio la necesidad de poder realizar a través de estudios en laboratorio en el año de 1971. En 1971, Hará y otros describieron una enzima proteínica en el fluido seminal llamada gammaseminoproteina. En 1978, Sensabaugh y otros, caracterizaron la proteína en detalle, fundamentando que su peso molecular corresponde a 30,000 Dalton, y fue llamada p30. En 1980, el primer ensayo inmunométrico fue desarrollado y, Graves y Sensabaugh, demostraron que el p30 es un marcador forense confiable para la identificación de semen, con lo que se podrá demostrar la identidad de la persona que cometió la violación. Objetivo: Determinar si la proteína P30 mediante una adecuada conservación en soportes sólidos mantiene los resultados de las pruebas obtenidas en delitos sexuales. Metodología: El estudio en la presente investigación se realizó en el laboratorio, para las determinaciones tanto de campo como bibliográfico. Resultados: Los ensayos realizados en el laboratorio de diferentes muestras en hisopos de secreción vaginal, que fueron recolectadas hace 1 año 2 meses, 2 años y de 5 años atrás se conservaron con los mismos resultados, con el que se tomó la muestra cuando dio positivo; la muestra en un guante de látex con un corte de 0.5 x 1 cm de la parte media con un tiempo se conservación de 4 años 5 meses, coincidía con el mismo resultado de positivo. Es decir que si se mantiene una adecuada conservación de la proteína P30 en soportes sólidos los resultados de las pruebas obtenidas en delitos sexuales serán los mismos sin alteración alguna. Conclusión: concluida la investigación se pudo comprobar que, si existe una buena conservación de la proteína P30 sin dejar que se contamine, al realizar otro análisis con el mismo procedimiento en el laboratorio, con el transcurso de los años obtendremos los mismos resultados con alta confiabilidad; los cuales servirán cuando sea necesario y se solicite por autoridad competente realizar un nuevo estudio en el laboratorio de las evidencias que sirvieron como apoyo en su momento, para resolver un cierto delito de violación.

Published: July 2024

Introducción. La escuela debería ser un espacio seguro para niños y adolescentes. En Ecuador la realidad es distinta, pues, cada vez se vuelven públicas las situaciones de delitos sexuales. Objetivo. Analizar los patrones y la frecuencia de los delitos sexuales en el ámbito educativo de la provincia de Chimborazo, durante el periodo de enero de 2014 a noviembre de 2023. Metodología. Enfoque cualitativo, empleando métodos hermenéuticos, interpretativos, históricos, dogmáticos y lógicos. Se llevó a cabo una revisión bibliográfica como técnica principal. Resultados. Muchos delitos sexuales no son enjuiciados debido a que no se ajustan al tipo penal, lo que resulta en una alta tasa de impunidad. Entre los delitos recurrentes se encuentran el abuso sexual, el acoso, la violación, el estupro y la pornografía infantil y adolescente. No existe relación entre los delitos sexuales denunciados y las pruebas presentadas. Conclusiones. La alta tasa de impunidad observada sugiere un subregistro judicial significativo de delitos sexuales. Los hallazgos resaltan la urgente necesidad de implementar medidas preventivas y de intervención temprana para abordar la recurrencia de los delitos sexuales en el sistema educativo ecuatoriano. Es importante fortalecer los métodos de recolección y análisis de evidencia forense en estos casos. Área de estudio general: (Derecho). Área de estudio específica: Criminalística y Ciencias Forenses.

Effect of forefoot transverse arch stiffness on foot biomechanical response--based on finite element method
Authors: Zhang Linjie , Zhang Qiaolin , Zhong Yilin , Hortobagyi Tibor , Gu Yaodong 
Published: July 2024

BackgroundThe plantar vault, comprising the transverse and longitudinal arches of the human foot, is essential for impact absorption, elastic energy storage, and propulsion. Recent research underscores the importance of the transverse arch, contributing over 40% to midfoot stiffness. This study aimed to quantify biomechanical responses in the ankle-foot complex by varying the stiffness of the deep metatarsal transverse ligament (DTML).MethodsUsing CT image reconstruction, we constructed a complex three-dimensional finite element model of the foot and ankle joint complex, accounting for geometric complexity and nonlinear characteristics. The focus of our study was to evaluate the effect of different forefoot transverse arch stiffness, that is, different Young’s modulus values of DTML (from 135 MPa to 405 MPa), on different biomechanical aspects of the foot and ankle complex. Notably, we analyzed their effects on plantar pressure distribution, metatarsal stress patterns, navicular subsidence, and plantar fascial strain.ResultsIncreasing the stiffness of the DTML has significant effects on foot biomechanics. Specifically, higher DTML stiffness leads to elevate von Mises stress in the 1st, 2nd, and 3rd metatarsals, while concurrently reducing plantar pressure by 14.2% when the Young’s modulus is doubled. This stiffening also impedes navicular bone subsidence and foot lengthening. Notably, a 100% increase in the Young’s modulus of DTML results in a 54.1% decrease in scaphoid subsidence and a 2.5% decrease in foot lengthening, which collectively contribute to a 33.1% enhancement in foot longitudinal stiffness. Additionally, doubling the Young’s modulus of DTML can reduce the strain stretch of the plantar fascia by 38.5%.ConclusionPreserving DTML integrity sustains the transverse arch, enhancing foot longitudinal stiffness and elastic responsiveness. These findings have implications for treating arch dysfunction and provide insights for shoe developers seeking to enhance propulsion.
The search for optimal nocturnal diurnal heart rate Index targets in ICU patients: a retrospective observational study from large ICU database

BackgroundCircadian rhythms play a crucial role in cardiovascular health, with the nocturnal diurnal heart rate index (NDHRI) reflecting significant circadian variations. However, the optimal NDHRI target in Intensive Care Unit (ICU) patients remains undefined. This study aims to establish an evidence-based NDHRI target range and assess its association with mortality.MethodsData from the eICU Collaborative Research Database (n = 32,412) were analyzed. NDHRI was calculated by dividing cumulative nighttime heart rate area by daytime area. Generalized additive models (GAMs) explored the non-linear relationship between mean NDHRI and mortality, adjusting for confounders. Subgroup analyses were conducted based on ethnicity, ICU type, and comorbidities.ResultsA U-shaped association was observed between hospital mortality and mean NDHRI (P &lt; 0.001). The optimal NDHRI range (40.0%–45.0%) demonstrated the lowest mortality rates. The duration spent within this range correlated inversely with mortality (P &lt; 0.001). Subgroup analyses consistently supported these findings across diverse patient profiles.ConclusionsOur findings suggest an association between maintaining NDHRI within the 40.0%–45.0% range and lower mortality rates in critically ill patients, highlighting the potential utility of monitoring circadian heart rate variations in the ICU. Further research and future randomized controlled trials are essential to confirm causality and should consider this NDHRI range as a pivotal reference target.
