Analysis of invasive diagnostic techniques for pathological confirmation of pleural mesothelioma.

BACKGROUND AND OBJECTIVES: Mesothelioma is an infrequent neoplasm with a poor prognosis that is related to exposure to asbestos and whose peak incidence in Europe is estimated from 2020. Its diagnosis is complex; imaging techniques and the performance of invasive pleural techniques being essential for pathological confirmation. The different diagnostic yields of these invasive techniques are collected in the medical literature. The present work consisted of reviewing how the definitive diagnosis of mesothelioma cases in our centre was reached to check if there was concordance with the data in the bibliography. MATERIALS AND METHODS: Retrospective review of patients with a diagnosis of pleural mesothelioma in the period 2019-2021, analysing demographic data and exposure to asbestos, the semiology of the radiological findings and the invasive techniques performed to reach the diagnosis. RESULTS: Twenty-six mesothelioma cases were reviewed. 22 men and 4 women. Median age 74 years. 9 patients had a history of asbestos exposure. Moderate-severe pleural effusion was the most frequent radiological finding (23/26). The sensitivity of the invasive techniques was as follows: Cytology 13%, biopsy without image guidance 11%, image-guided biopsy 93%, surgical biopsy 67%. CONCLUSIONS: In our review, pleural biopsy performed with image guidance was the test that had the highest diagnostic yield, so it should be considered as the initial invasive test for the study of mesothelioma.

Intravascular imaging-guided percutaneous coronary intervention in patients with acute myocardial infarction and cardiogenic shock.

INTRODUCTION AND OBJECTIVES: There are no clinical data on the efficacy of intravascular imaging-guided percutaneous coronary intervention (PCI) compared with angiography-guided PCI in patients with acute myocardial infarction (AMI) and cardiogenic shock. The current study sought to evaluate the impact of intravascular imaging-guided PCI in patients with AMI and cardiogenic shock. METHODS: Among a total of 28 732 patients from the nationwide pooled registry of KAMIR-NIH (November, 2011 to December, 2015) and KAMIR-Ⅴ (January, 2016 to June, 2020), we selected a total of 1833 patients (6.4%) with AMI and cardiogenic shock who underwent PCI of the culprit vessel. The primary endpoint was major adverse cardiovascular events (MACE) at 1 year, a composite of cardiac death, myocardial infarction, repeat revascularization, and definite or probable stent thrombosis. RESULTS: Among the study population, 375 patients (20.5%) underwent intravascular imaging-guided PCI and 1458 patients (79.5%) underwent angiography-guided PCI. Intravascular imaging-guided PCI was associated with a significantly lower risk of 1-year MACE than angiography-guided PCI (19.5% vs 28.2%; HR, 0.59; 95%CI, 0.45-0.77; P < .001), mainly driven by a lower risk of cardiac death (13.7% vs 24.0%; adjusted HR, 0.53; 95%CI, 0.39-0.72; P < .001). These results were consistent in propensity score matching (HR, 0.68; 95%CI, 0.46-0.99), inverse probability weighting (HR, 0.61; 95%CI, 0.45-0.83), and Bayesian analysis (Odds ratio, 0.66, 95% credible interval, 0.49-0.88). CONCLUSIONS: In AMI patients with cardiogenic shock, intravascular imaging-guided PCI was associated with a lower risk of MACE at 1-year than angiography-guided PCI, mainly driven by the lower risk of cardiac death.

Update on cardiac imaging: A critical analysis.

Imaging is instrumental in diagnosing and directing the management of atherosclerosis. In 1958 the first diagnostic coronary angiography (CA) was performed, and since then further development has led to new methods such as coronary CT angiography (CTA), optical coherence tomography (OCT), positron tomography (PET), and intravascular ultrasound (IVUS). Currently, CA remains powerful for visualizing coronary arteries; however, recent studies show the benefits of using other non-invasive techniques. This review identifies optimum imaging techniques for diagnosing and monitoring plaque stability. This becomes even direr now, given the rapidly rising incidence of atherosclerosis in society today. Many acute coronary events, including acute myocardial infarctions and sudden deaths, are attributable to plaque rupture. Although fatal, these events can be preventable. We discuss the factors affecting plaque integrity, such as increased inflammation, medications like statins, and increased lipid content. Some of these precipitating factors are identifiable through imaging. However, we also highlight significant complications arising in some modalities; in CA this can include ventricular arrhythmia and even death. Extending this, we elucidated from the literature that risk can also vary based on the location of arteries and their plaques. Promisingly, there are less invasive methods being trialled for assessing plaque stability, such as Cardiac Magnetic Resonance Imaging (CMR), which is already in use for other cardiac diseases like cardiomyopathies. Therefore, future research focusing on using imaging modalities in conjunction may be sensible, to bridge between the effectiveness of modalities, at the expense of increased complications, and vice versa.

Cavitación coroidea asociada a coloboma macular. Estudio multimodal. Imagen en face / Choroid cavitation associated with macular coloboma. Multimodal study. Image en face

La cavitación intracoroidea es un hallazgo identificado con OCT descrito inicialmente en pacientes miopes, pero también aparece en pacientes no miopes. Puede presentarse tanto en el área peripapilar como en el polo posterior. El coloboma macular es un defecto del desarrollo embrionario del polo posterior, y en la OCT estructural es imprescindible la ausencia del epitelio pigmentario de la retina y de los vasos coroideos para su diagnóstico. Este caso presenta la cavitación intracoroidea circunscribiendo el coloboma macular, en ausencia de membrana intercalar. La imagen en face permite valorar la relación entre ambas estructuras, así como la magnitud de las mismas. (AU)

Intrachoroidal cavitation is a finding identified with OCT initially described in myopic patients, it also appears in non-myopic patients. It can occur in both the peripapillary area and the posterior pole. Macular coloboma is a defect of embryonic development of the posterior pole, in structural OCT the absence of the retinal pigment epithelium and choroidal vessels is essential. In this case, intrachoroidal cavitation circumscribes the macular coloboma, in the absence of an intercalary membrane. The face image allows us to assess the relationship between the two structures as well as their magnitude. (AU)

Sexual quality of life and body image of breast cancer patients: uncovering the meaning behind the symptoms / Calidad de vida sexual e imagen corporal de pacientes con cáncer de mama: descubriendo el significado detrás de los síntomas

Abstract: Introduction: Breast cancer symptoms and the side effects of treatment can significantly affect different domains of women’s functioning. Objective: The aim of this study was to examine the quality of life in women with breast cancer. Method: Our sample consisted of 240 women aged 30-68 (M=52, SD=8.68). Approximately 50% had undergone a mastectomy, while 40% had breast reconstruction. A structured questionnaire consisted of social-demographical data, SQOL-F, EORTC QLQ-C30 & EORTC QLQ-BR23. Results: Results suggest that our BC patients had lower quality of life and more financial difficulties than in most other studies, implying some cultural or health system differences. Not having a mastectomy was associated with better sexual quality of life, global health, and physical functioning. In contrast, women who underwent mastectomy reported impaired body image and sexual functioning, with more prominent breast symptoms. Reconstruction was related to the lower quality of life and no improvement in body image. Conclusions: Sexual quality of life was mainly related to global health status, emotional functioning, treatment side effects and body image. Emotional functioning and side effects were significant predictors of sexual quality of life, while impaired sexual functioning was associated with distorted body image. These findings can serve as guidance for forming interventions aimed at enhancing the quality of life. (AU)

Resumen:Introducción: Los síntomas del cáncer de mama y los efectos secundarios del tratamiento pueden afectar significativamente a diferentes áreas funcionales de las mujeres. Objetivo: examinar la calidad de vida de mujeres con cáncer de mama. Método: la muestra estuvo compuesta por 240 mujeres de entre 30 y 68 años (M=52; DT=8,68). Aproximadamente el 50% se había sometido a una mastectomía, mientras que al 40% se le había realizado una reconstrucción mamaria. Un cuestionario estructurado constaba de datos sociodemográficos, SQOL-F, EORTC QLQ-C30 y EORTC QLQ-BR23. Resultados: Los resultados sugieren que nuestros pacientes con BC tenían una menor calidad de vida y más dificultades financieras que en la mayoría de los otros estudios, lo que implica algunas diferencias culturales o del sistema de salud. No someterse a una mastectomía se asoció con una mejor calidad de vida sexual, salud global y funcionamiento físico. Por el contrario, las mujeres que se sometieron a mastectomía informaron problemas de imagen corporal y funcionamiento sexual, con síntomas mamarios más prominentes. La reconstrucción se relacionó con una menor calidad de vida y ninguna mejora en la imagen corporal. Conclusiones: La calidad de vida sexual se relacionó principalmente con el estado de salud global, el funcionamiento emocional, los efectos secundarios del tratamiento y la imagen corporal. El funcionamiento emocional y los efectos secundarios fueron predictores importantes de la calidad de vida sexual, mientras que el funcionamiento sexual deteriorado se asoció con una imagen corporal distorsionada. Estos hallazgos pueden servir como guía para formular intervenciones destinadas a mejorar la calidad de vida. (AU)

Percepção e satisfação corporal de estudantes universitários vegetarianos / Perception and body satisfaction of vegetarian students / Percepción y satisfacción corporal de los estudiantes vegetarianos

INTRODUÇÃO: A percepção e satisfação corporal têm sido amplamente estudadas em diversos públicos, principalmente em estudantes universitários; porém, existem poucas investigações com vegetarianos, sendo assim, torna-se necessário avaliar se o padrão alimentar vegetariano está relacionado com os fenômenos inerentes à imagem corporal. OBJETIVO: Avaliar a percepção e a satisfação corporal entre estudantes universitários vegetarianos. MÉTODO: Trata-se de um estudo transversal com 123 participantes, no qual foram aplicados o Questionário de Imagem Corporal - BSQ (Body Shape Questionnaire) e a Escala de Silhuetas de Stunkard. RESULTADOS: Os dados mostraram que 86,2% dos participantes eram eutróficos (IMC=22,4±3,3), sendo o score obtido no BSQ foi de 84,6 pontos (±36,0) correspondente à leve insatisfação com a imagem corporal. Cerca de 82,1% dos estudantes se mostravam insatisfeitos com a silhueta, dentre estes, 61,4% desejavam diminuí-la. CONCLUSÃO: O padrão alimentar (ovolactovegetariano, lactovegetariano, vegetariano estrito e vegano) não se relacionou com a insatisfação corporal, mas sim o desejo de ter silhuetas magras que são valorizadas pelo padrão de beleza vigente.

INTRODUCTION: For Body perception and satisfaction have been widely studied among different publics, especially among college students; however, there are few investigations with vegetarians. Therefore, it is necessary to evaluate whether the vegetarian eating pattern is related to the phenomena inherent to body image. OBJECTIVE: To evaluate body perception and body satisfaction among vegetarian college students. METHOD: This is a cross-sectional study with 123 participants, in which the Body Image Questionnaire (BSQ) and the Stunkard Silhouette Scale were applied. RESULTS: The data showed that 86.2% of the participants were eutrophic (BMI=22.4±3.3), and the score obtained in the BSQ was 84.6 points (±36.0) corresponding to a mild dissatisfaction with body image. About 82.1% of the students were dissatisfied with their silhouette, and 61.4% of them wanted to reduce it. CONCLUSION: Dietary patterns (ovolactovegetarian, lactovegetarian, strict vegetarian, and vegan) were not related to body dissatisfaction, but rather the desire to have thin silhouettes that are valued by the prevailing beauty standard.

SmartAnalysis: A sustainable digital-image colorimetry method for ethanol determination in alcohol-based hand sanitizer / SmartAnalysis: Un método sostenible de colorimetría de imagen digital para la determinación de etanol en desinfectante de manos a base de alcohol

Introducción: El consumo de desinfectantes de manos a base de alcohol ha aumentado significativamente después de la pandemia causada por el SARS-CoV-2. A pesar de la conclusión de la emergencia sanitaria declarada por la OMS en 2023, la costumbre de desinfectar las manos con geles sanitizantes a base de etanol ha sido adoptada a nivel mundial por la población. Dado que los métodos generales descritos en los compendios oficiales para la de-terminación del etanol, como la cromatografía de gases o la destilación, son laboriosos y no específicos para geles que contienen carbómero, este trabajo propone un método alternativo basado em la colorimetría de imágenes digitales. Método: La imagen digital (proporcionada por la reacción etanol-fenolftaleína) fue capturada y transformada en una señal analítica basada en el sistema de colores Rojo-Verde-Azul. Las adquisiciones de imágenes se realizaron utilizando un smartphone Samsung Galaxy J6, y las señales se generaron mediante el programa gratuito Photometrix Pro®. El método fue validado de acuerdo con las directrices de la ICH y se aplicó en muestras comerciales. Además, el método propuesto fue evaluado por su impacto ambiental utilizando la herramienta Índice del Proceso Analítico Verde (GAPI). Se generaron pictogramas utilizando el programa gratuito ComplexGAPI®.Resultados: El canal verde mostró una respuesta lineal en las curvas de calibración para concentraciones de etanol que van desde el 5 hasta el 40 % (p/p) en medio ácido. El método demostró linearidad, precisión, exactitud y robustez. Conclusiones: El método propuesto presentó como principales ventajas el uso de dispositivos de bajo costo y fáciles de manejar, así como un consumo reducido de reactivos, de acuerdo con los principios de la química analítica verde. (AU)

Introduction: The consumption of alcohol-based hand sanitizers has increased significantly after the pandemic caused by SARS-CoV-2. Despite the conclusion of the health emergency declared by the WHO in 2023, the habit of sanitizing hands with ethanol-based gel sanitizers has been globally adopted by the population. Since general methods described in official compendia for ethanol determination such as gas chromatography or distillation are laborious and not-specific to carbomer-containing gels, this work proposes an alternative method based on digital image colorimetry. Method: The digital image (provided by ethanol-phenolphthalein reaction) was captured and transformed into an analytical signal based on the Red-Green-Blue system. The image acquisitions were performed using a Samsung Galaxy J6 smartphone, and the signals were generated using the Photometrix Pro® free program. The method was validated in accordance with ICH and applied in commercial samples. Additionally, the proposed method was eval-uated for its environmental impact using the Green Analytical Process Index (GAPI) tool. Pictograms were generated using the ComplexGAPI® free program. Results: Green channel exhibited a linear response in the calibration curves for ethanol concentrations ranging from 5 to 40 % (w/w) in acidic medium. The method showed linearity, precision, accuracy, and robustness. Conclusions: The proposed method presented as main advantages the use of low-cost and easy-to-handle devices and reduced reagent consumption, in accordance with green analytical chemistry principles.

The R.E.N.A.L. and PADUA renal nephrometry scores have moderate predictive power for complications associated with percutaneous cryoablation of renal tumors. (AU)

Digital imaging, virtual and augmented reality.

The sensorial perception of what is captured is what we know as "image" and consists of a static component and a dynamic process. This continuous process of images capture is essential in surgery. The image is crucial for the surgeon, who requires it for the diagnosis, for the therapeutic process and for postoperative follow-up. In minimally invasive surgery the sequence of images is essential and promotes the appearance of digital video. Digital video is the representation of moving images in the form of encoded digital data, unlike classic analog video, with continuous analog signals. Beyond what we can consider the "real image" (what we see as part of the existing reality) other realities appear in these decades; the Virtual Reality and Augmented Reality. With these realities we refer in the medical ambitus to the creation or superposition, respectively, of a three-dimensional virtual environment to support healthcare and teaching or research processes. Today, these technologies have already begun to be integrated into various surgical specialties, with predictive surgical planning and intraoperative navigation us their main applications. When using these digital environments, it is difficult to completely separate virtual reality from augmented reality, often being Mixed Reality. The current developments offer an environment that mixes the best aspects of both, unifying the simulation and requiring a single helmet or glasses to enjoy the sensorial experience. In this fusion of realities it will be possible to simultaneously create a virtual world from scratch to which we can add virtual elements from our real environment.

Choroid cavitation associated with macular coloboma. Multimodal study. Image en face.

Intrachoroidal cavitation is a finding identified with OCT initially described in myopic patients, it also appears in non-myopic patients. It can occur in both the peripapillary area and the posterior pole. Macular coloboma is a defect of embryonic development of the posterior pole, in structural OCT the absence of the retinal pigment epithelium and choroidal vessels is essential. In this case, intrachoroidal cavitation circumscribes the macular coloboma, in the absence of an intercalary membrane. The en face image allows us to assess the relationship between the two structures as well as their magnitude.

Papel de la imagen de movimiento incoherente intravóxel (IVIM) en la evaluación de la respuesta del carcinoma hepatocelular después de la quimioembolización transarterial (TACE): un estudio prospectivo / Role of intravoxel incoherent motion (IVIM) imaging in response assessment of hepatocellular carcinoma after transarterial chemoembolization (TACE): a prospective study

Introducción: La evaluación de la respuesta del carcinoma hepatocelular (CHC) se basa actualmente en el realce en la fase arterial, que no tiene en cuenta los cambios microestructurales en el tumor después de la quimioembolización transarterial (TACE). Objetivo: Este estudio prospectivo se llevó a cabo para evaluar la viabilidad y la eficacia de la imagen de movimiento incoherente intravóxel (IVIM) en la evaluación de la respuesta de CHC después de TACE. A 39 pacientes cirróticos con 48 CHC se les realizó una resonancia magnética (RM) 1 semana antes y 6 semanas después de la TACE. Se midieron parámetros IVIM como Dlenta (difusión verdadera), Drápida (seudodifusión), la fracción de perfusión y el ADC antes y después de la TACE. Los valores antes y después de la TACE en las lesiones LR-TR no viables y viables según la clasificación LI-RADS de categorías de respuesta al tratamiento se compararon mediante pruebas t emparejadas. Se realizó un análisis de la curva ROC para calcular la sensibilidad y la especificidad y proponer valores de corte.Resultado: Las lesiones no viables mostraron un aumento significativo de la Dlenta (1,208±0,581 frente a 1,560±0,494, valor de p=–0,0207) y de ADC (1,37±0,53 frente a 1,65±0,4287, valor de p=–0,016) después de la TACE. También se observó una disminución significativa de los valores de Drápida (33,7±10,4 frente a 23,75±12,13, valor de p=0,0005) y f (19,92±10,54 frente a 12,9±10,41, valor de p=0,012) después de la TACE en las lesiones no viables en comparación con las viables. El cambio en la difusión verdadera tuvo el mayor AUC (0,741) entre los parámetros IVIM, con un aumento superior a 0,075 entre los valores previos y posteriores a la TACE, con una sensibilidad y especificidad del 81,8 y el 60%, respectivamente, para la respuesta completa. Conclusión: La IVIM es factible para evaluar la respuesta en el CHC después de la TACE. La difusión verdadera es más sensible y específica que la difusión aparente para...(AU)

Introduction: Response evaluation of hepatocellular carcinoma (HCC) currently is based on arterial phase enhancement which doesn’t take into microstructural changes in the tumor after trans-arterial chemoembolization (TACE). Aim: This prospective study was conducted to assess the feasibility and efficacy of intravoxel incoherent motion imaging (IVIM) in response evaluation of HCC after TACE. 39 cirrhotic patients with 48 HCC underwent MR imaging 1 week within and 6weeks after TACE. IVIM parameters like Dslow (true diffusion), Dfast (pseudodiffusion), perfusion fraction and ADC were measured prior to and postTACE. The pre and postTACE values in LR-TR (LIRADS-treatment response) nonviable and viable lesions were compared using paired t-tests. ROC curve analysis was done to calculate sensitivity and specificity and propose cut-off values. Result: Non-viable lesions showed a significant increase in Dslow (1.208±0.581 vs. 1.560±0.494, p-value –0.0207) and ADC (1.37±0.53 vs. 1.65±0.4287, p-value 0.016) after TACE. There was also significant decrease in Dfast (33.7±10.4 vs. 23.75±12.13, p-value 0.0005) and f (19.92±10.54 vs. 12.9±10.41, p-value 0.012) values after TACE in non-viable lesions compared to viable lesions. The change in true diffusion had the highest AUC (0.741) among IVIM parameters with greater than 0.075 increase between preTACE and postTACE values having a sensitivity and specificity of 81.8% and 60% respectively for complete response. Conclusion: IVIM imaging is feasible to assess the response in HCC after TACE. True diffusion is more sensitive and specific than apparent diffusion in evaluating the response.(AU)

Se encontró una diferencia significativa entre hombres y mujeres en términos de estado de ánimo, condición física y factores de control del peso corporal en la selección de alimentos (p<0,05). El factor de control del estado emocional y del peso corporal afecta positivamente a la ortorexia nerviosa, mientras que el factor de atracción sensorial afecta negativamente a la ortorexia nerviosa (p<0,05 ß=0,260, ß=0,291, ß= -0,426). No hubo diferencia significativa en cuanto a los factores considerados en la selección de alimentos según el estado de actividad física de los trabajadores de la salud (p<0,05).Conclusión: Se observó que la insatisfacción con la imagen corporal de las mujeres fue mayor que la de los hombres. El promedio de los factores de control del estado de ánimo, el estado físico y el peso corporal a los que las mujeres prestan atención en la selección de alimentos tienen un efecto mayor que los hombres. Se consideró que las actividades físicas de los trabajadores de la salud eran insuficientes.(AU)

Objective: This study was conducted to change the nutri-tional choices of healthcare professionals according to bodyimage, healthy orthorexia and physical activity.Methods: This study was conducted in a private hospitalbetween December 2022 and February 2023 with 95 femaleand 42 male healthcare professionals who agreed to partici-pate in the research. A face-to-face survey form was used forhealthcare workers and general information, information onhealth and nutritional status, anthropometric measurements(height (cm), body weight ((kg)), Body Shape Questionnaire(BSQ-34), Teruel Orthorexia Scale (TOS) were collected, FoodChoice Questionnaire (FCQ), International Physical ActivityQuestionnaire (IPAQ). Results: The average BMI of healthcare workers is withinthe normal range (24.8±4.43kg/m2). There was a significantdifference between genders in terms of body shape dissatis-faction, and it was found that women were more likely thanmen (p<0.05). While the average BSQ-34 score of obese pe-ople is highest, the average decreases as the BMI level dec-reases. There is a significant relationship between gender andBMI in those who do not have body shape dissatisfaction andthose who have mild dissatisfaction (p<0.05). There is a sig-nificant difference between genders in terms of mood, fitnessand body weight control factors in food selection, and theaverage for women is higher than for men (p<0.05). As bodyshape dissatisfaction increases, the average mood factor infood selection increases. Age positively affects healthy ortho-rexia (p<0.05, ß=0.269). The level of body shape dissatisfaction positively affects orthorexia nervosa (ß=0.409, p<0.05).In the case of healthy orthorexia, there is a significant posi-tive relationship between food choice and health (ß=0.326,p<0.05), and a negative relationship between the sensoryattractiveness factor (ß=-0.248, p<0.05)...(AU)

Innovación continuada en cirugía radioguiada de precisión / Continuous innovation in precision radio-guided surgery

Desde sus inicios, la medicina nuclear se ha enfrentado a cambios tecnológicos que la han obligado a modificar sus modos operativos y a adecuar sus protocolos. En el campo de la cirugía radioguiada (CRG), la incorporación de la imagen gammagráfica preoperatoria y la detección intraoperatoria con la sonda gamma proporcionó un impulso definitivo a la biopsia del ganglio centinela (GC) para convertirse en el procedimiento estándar de aplicación en el melanoma y el cáncer de mama. Las diversas innovaciones tecnológicas y la adaptación consiguiente de protocolos confluyen en lo disruptivo y lo gradual. Como ejemplos evidentes tenemos la introducción de la tomografía por emisión de fotón único/tomografía computarizada (SPECT/TC) en el campo preoperatorio y las sondas Drop-in (Lightpoint Medical Ltd; Crystal photonics, Eurorad) en el intraoperatorio. Otros aspectos innovadores con posible aplicación en la CRG se basan en la utilización de la inteligencia artificial (IA), navegación y teleasistencia (AU)

Since its origins, nuclear medicine has faced technological changes that led to modifying operating modes and adapting protocols. In the field of radioguided surgery, the incorporation of preoperative scintigraphic imaging and intraoperative detection with the gamma probe provided a definitive boost to sentinel lymph node biopsy to become a standard procedure for melanoma and breast cancer. The various technological innovations and consequent adaptation of protocols come together in the coexistence of the disruptive and the gradual. As obvious examples we have the introduction of SPECT/CT in the preoperative field and Drop-in probes in the intraoperative field. Other innovative aspects with possible application in radio-guided surgery are based on the application of artificial intelligence, navigation and telecare (AU)

Retro-mode imaging for the diagnosis of optic disc drusen: a case series.

OBJECTIVE: We aimed to compare the detectability of optic disc drusen (ODD), using various non-invasive imaging techniques, including the novel retro-mode imaging (RMI), as well as to analyze the morphological characteristics of ODD on RMI. METHODS: This study involved seven patients with bilateral ODD, totaling 14 eyes. Multimodal imaging techniques, including multicolor fundus photography (MC), near-infrared reflectance (NIR), green and blue light fundus autofluorescence (G-FAF and B-FAF, respectively), and RMI were used to examine the eyes. FAF was used as the primary method of identifying ODD, and each method's detection rate was compared by two observers. Quantitative measurements of ODD included the number of ODD visualized by the RMI technique, the perimeter (P) and area (A) of ODD were identified. RESULTS: The average age of the patients included was 49.28 ±â€¯23.16 years, with five of the seven being men. RMI was able to detect ODD in all cases, with a sensitivity of 100%, compared to MC (sensitivity 60.71%), NIR (sensitivity 60.71%), B-FAF (sensitivity 100%), G-FAF (sensitivity 100%). RMI was the only imaging technique capable of assessing ODD morphology and quantifying ODD. CONCLUSIONS: RMI is a promising imaging modality for diagnosing superficial ODD, providing valuable information on the distribution, location, and size of ODD. We suggest the incorporation of RMI as a complementary tool for diagnosing and monitoring ODD in combination with other multimodal imaging methods.

Jung's Erotic Phenomenology: I. A New Translation.

In the introduction to The Psychology of the Transference (1946), Carl Jung sketched out a theory of "erotic phenomenology" which condenses his teaching about sexuality and romantic love into a very concise summary. But the meaning of this passage is obscured in the English translation given in the Collected Works of C. G. Jung. I propose here a new translation which makes Jung's meaning clearer, along with a commentary which explains it in the context of Freudian drive theory and German 19th century philosophy. Invoking the concepts of instinct, mind, and Eros (both the passion and the divine figure), Jung's theory says that male sexual desire can be cultivated or repressed in four distinct ways, each associated with a female symbolic figure or anima image: Eve, Helen, Mary and Sophia.

Dans son introduction à La Psychologie du Transfert (1946), Carl Jung esquisse une « phénoménologie érotique ¼ qui condense ses enseignements sur la sexualité et le désir en un résumé très concis. Mais le sens de ce passage est brouillé dans la traduction anglaise des Collected Works of C.G. Jung. Je propose ici une nouvelle traduction qui rend l'argument de Jung plus clair, suivie d'un commentaire qui l'explique dans le contexte de la théorie freudienne des pulsions et de la philosophie allemande du XIXe siècle. Invoquant les concepts d'instinct, d'esprit et d'Eros (en tant que passion ainsi que figure divine), la théorie de Jung dit que le désir sexuel masculin peut être cultivé ou réprimé de quatre manières distinctes, chacune associée à une figure symbolique féminine ou image de l'anima: Eve, Hélène, Marie et Sophia.

En la introducción a La Psicología de la Transferencia (1946), Carl Jung esbozó una "fenomenología erótica" que condensa sus enseñanzas sobre la sexualidad y el amor romántico en un resumen muy conciso. Pero el significado de este pasaje queda opacado en la traducción inglesa de las Obras Completas de C.G. Jung. Propongo aquí una nueva traducción que aclara el significado de Jung, junto con un comentario que lo explica en el contexto de la teoría freudiana de la pulsión y la filosofía alemana del siglo XIX. Invocando los conceptos de instinto, mente y Eros (tanto la pasión como la figura divina), la teoría de Jung expresa que el deseo sexual masculino puede cultivarse o reprimirse de cuatro maneras distintas, cada una asociada a una figura simbólica femenina o imagen del ánima: Eva, Helena, María y Sofía.

Role of intravoxel incoherent motion (IVIM) imaging in response assessment of hepatocellular carcinoma after transarterial chemoembolization (TACE) - A prospective study.

INTRODUCTION: Response evaluation of hepatocellular carcinoma (HCC) currently is based on arterial phase enhancement which doesn't take into microstructural changes in the tumor after trans-arterial chemoembolization (TACE). AIM: This prospective study was conducted to assess the feasibility and efficacy of intravascular incoherent motion imaging (IVIM) in response evaluation of HCC after TACE. 39 cirrhotic patients with 48 HCC underwent MR imaging 1 week within and 6weeks after TACE. IVIM parameters like Dslow (true diffusion), Dfast (pseudodiffusion), perfusion fraction and ADC were measured prior to and postTACE. The pre and post TACE values in LR-TR (LIRADS - treatment response) nonviable and viable lesions were compared using paired t-tests. ROC curve analysis was done to calculate sensitivity and specificity and propose cut-off values. RESULT: Non-viable lesions showed a significant increase in Dslow (1.208 ± 0.581 vs 1.560 ± 0.494, P-value -.0207) and ADC (1.37 ± 0.53 vs 1.65 ± 0.4287, P value .016) after TACE. There was also significant decrease in Dfast (33.7 ± 10.4 vs 23.75 ± 12.13, P value .0005) and f (19.92 ± 10.54 vs 12.9 ± 10.41, P value .012) values after TACE in non-viable lesions compared to viable lesions. The change in true diffusion had the highest AUC (0.741) among IVIM parameters with greater than 0.075 increase between preTACE and postTACE values having a sensitivity and specificity of 81.8% and 60% respectively for complete response. CONCLUSION: IVIM imaging is feasible to assess the response in HCC after TACE. True diffusion is more sensitive and specific than apparent diffusion in evaluating the response.

Role of the clinical radiopharmacist in patient safety during myocardial perfusion imaging with vasodilator stress agents.

AIM: To assess the radiopharmacist's role in a multidisciplinary team focused on the contraindications of regadenoson in order to ensure the safe use of pharmacologic vasodilator stress agents in patients undergoing SPECT-MPI. METHODS: We ambispectively studied its safe use in 1905 patients (54.1% female, mean age: 66.6±11.7 years, range: 20-95 years). Sex, age, medical history, medications, drug allergies, and contraindications for stress testing were registered together with recommendations for the nuclear physician in charge. RESULTS: Detected contraindications and corresponding recommendations were as follows: risk factors for QTc interval prolongation 7.5% - measurement of QTc interval previously to test and monitor ECG; prior stroke or TIA 4.2% - consider carotid stenosis assessment; salicylates/sulfonamides allergy 3.1% - use 99mTc-sestamibi; epilepsy or risk factors for seizures 2.4% - use of adenosine or reconsider test indication; systemic corticosteroid therapy for severe COPD 1.3% - reassessment of patient's condition; acute exacerbation of COPD 0.8% - defer test until acute episode is over; severe asthma 0.4% - do not perform test; methylxanthine ingestion 0.3% - avoid consumption previously; other 6.1% - evaluation of other contraindications. No contraindications were detected in 73.6% of patients. The test was canceled due to absolute contraindications in 2.9% of the requests. CONCLUSIONS: Working in a systematic way, the radiopharmacist was able to detect a high number of issues related to regadenoson, with one out of four patients presenting some clinical contraindication. The recommendations given by the radiopharmacist were well accepted by the nuclear physicians who changed their approach contributing to increase the safety of patients referred for MPI.

Determination of body image and self-efficacy levels in patients after cornea transplantation.

PURPOSE: The study aimed to determine body image and levels after surgery in cornea transplant patients. MATERIALS AND METHODS: The population of this cross-sectional study was composed of 383 patients presented to the Eye Bank unit of a University Hospital after corneal transplantation. Sample size of 193 patients was calculated with 0.5 power, a margin of error of 5%, representing 95% of the universe. The data were collected through face-to-face interviews with the patients by the researcher and the study was completed with 178 patients in September-November 2022. The data were collected using a Patient Information Form, the Body Image Scale, and the General Self-Efficacy Scale. Parametric tests, Pearson Correlation, Student's t-test, and One-Way Analysis of Variance tests were performed were used in the data analysis. RESULTS: It was determined that the mean Body Image Scale score of the transplant patients participating in the study was 159.41 ±â€¯36.99 and the mean Self-Efficacy Scale score was 30.37 ±â€¯8.31. When the comparison of the mean scores was examined, the difference between the mean scores of gender, marital status, occupation, and body image scale was statistically significant (p < .05), while the difference between the self-efficacy mean scores was not statistically significant (p > .05). There was a positive, moderately strong significant relationship between body image and the self-efficacy of the patients (p < .01) (r = .57). CONCLUSION: It was found that the patient's body image and self-efficacy levels were high, and self-efficacy increased as the body image increased.

Enfermedad de Lhermitte-Duclos y síndrome de Cowden. Reporte de un caso / Lhermitte-Duclos Disease and Cowden Syndrome. A Case Report

Presentación del caso. Se trata de una paciente femenina de 45 años con antecedentes de hipertensión arterial y múltiples cirugías por cáncer, entre ellas, cáncer de tiroides, carcinoma de parótida, cáncer de mama y cáncer endometrial. De manera incidental se identificó una lesión en el hemisferio cerebeloso derecho en una tomografía de senos paranasales, que fue confirmada a través de una resonancia magnética cerebral. La lesión presentaba una apariencia estriada, característica de gangliocitoma displásico del cerebelo o enfermedad de Lhermitte-Duclos. Considerando los antecedentes de diversos tipos de cáncer y los criterios de diagnóstico propuestos por el Consorcio Internacional Cowden y la Red Nacional Integral del Cáncer, se estableció el diagnóstico de síndrome de Cowden que había pasado desapercibido hasta el momento. Intervención terapéutica. Posteriormente, la paciente fue hospitalizada debido al crecimiento de una masa metastásica en el hemicuello derecho con afectación del plexo braquial, adenopatías cervicales, infraclaviculares y axilares derechas. Evolución clínica. En la actualidad, se encuentra recibiendo tratamiento paliativo con el objetivo de controlar los síntomas y mejorar su calidad de vida, ya que expresó su negativa a someterse a una intervención quirúrgica de resección tumoral

Case presentation. The report is of a 45-year-old female patient with a history of high blood pressure and multiple surgeries for cancer, including thyroid cancer, parotid carcinoma, breast cancer, and endometrial cancer. Incidentally, a lesion in the right cerebellar hemisphere was identified in a tomography of the paranasal sinuses, which was later confirmed in a brain magnetic resonance. The lesion had a striated appearance, characteristic of dysplastic gangliocytoma of the cerebellum or Lhermitte-Duclos disease. Considering the history of various types of cancer and the diagnostic criteria proposed by the International Cowden Consortium and the National Comprehensive Cancer Network, the diagnosis of Cowden syndrome, which had gone unnoticed until now, was established. Treatment. Subsequently, the patient was hospitalized due to the growth of a metastatic mass in the right hemicollar with involvement of the brachial plexus, cervical, infraclavicular, and right axillary lymph nodes. Outcome. She is receiving palliative treatment to control the symptoms and improve her quality of life, since she expressed her refusal to undergo tumor resection surgery
