Authors: Vera-Alanis Yuliana , Cano-Verdugo Guillermo 
Published: October 2023

Introducción: El cáncer de mama en hombres es una enfermedad poco frecuente que trae consecuencias directas relacionadas con la calidad de vida, la apariencia física y la función sexual. El objetivo fue sintetizar la información sobre la función sexual en hombres con cáncer de mama.
Materiales y métodos: Se realizó una revisión de alcance mediante la búsqueda de información disponible en las bases de datos PubMed, DOAJ, Scientific Research Publishing y National Library of Medicine. Se utilizaron conceptos relacionados con el cáncer de mama en hombres y la función sexual. Se identificaron 73 artículos y se seleccionaron 25.
Resultados: El análisis identificó cuatro tipos de repercusiones del cáncer de mama con respecto a la sexualidad: a nivel de actividad sexual, a nivel corporal, a nivel hormonal y a nivel socioemocional. Se encontró que tanto el diagnóstico como su tratamiento, especialmente el tamoxifeno, provocan disminución o ausencia de deseo sexual, disfunción eréctil, inflamación y dolor de la mama afectada, retracción y supuración del pezón, alteraciones del estado de ánimo, depresión y masculinidad afectada.
Conclusiones: Los hombres con cáncer de mama presentan condiciones adversas relacionadas con su patología y tratamiento que pueden reducir su función sexual y su calidad de vida.

Introducción: México es un país con grandes depósitos naturales de plomo y se estima que el mundo genera alrededor de 12 a 130,000 toneladas/año y su principal vía de introducción al ambiente es por la atmósfera. El propósito del presente trabajo es identificar si existen lesiones en corazón, pulmones y cerebro después de una exposición cutánea al plomo en ratones.

Material y Métodos: Se seleccionaron 40 ratones sanos: 24 machos y 16 hembras; se les aplicó óxido de plomo (GRETA) por vía cutánea y las dosis fueron de 2,4, 6,8 y 10 mg de óxido de plomo. Se aplicó diario de lunes a sábado, estableciendo 5 lotes de 8 ratones en cada grupo; más un grupo control también de 8 ratones. Cada semana se sacrificó un ratón al azar de cada grupo y 5 ratones fallecieron antes de concluir el experimento. De cada órgano se consignó su coloración, tamaño, aspecto externo, fragilidad del tejido en general, tiempo de exposición al plomo y cambios histopatológicos en los tejidos.

Resultados: En los 40 ratones expuestos se presentó congestión pulmonar en grado moderado, en 33 de ellos (82%) se encontró edema pulmonar de tipo no cardiogénico y en 1 existió coágulo de fibrina. En corazón se presentó congestión vascular moderada en el 97% de los ratones (39 de ellos) y en el 5% (2 ratones) se encontró necrosis leve. En el cerebro las alteraciones fueron edema en todos los ratones expuestos, con necrosis neuronal en el 88% (35 ratones) y gliosis neuronal reactiva en el 10% (4 ratones), con estas alteraciones los ratones perdieron coordinación en sus movimientos.

Discusión:
El presente trabajo mostró que el plomo aplicado por vía cutánea es capaz de absorberse. La mayoría de los mecanismos de toxicidad del plomo han sido estudiados en procesos bioquímicos y afectan sobre todo enzimas en procesos celulares. La frecuencia y la severidad de los síntomas médicos se relaciona con la concentración de plomo en la sangre.

Conclusiones: Por la piel la entrada del plomo inorgánico es mínima, pero el plomo orgánico pasa a través de los folículos pilosos, glándulas sebáceas y sudoríparas directo al torrente sanguíneo. El plomo constituye una parte importante de la contaminación ambiental, el empleo de este metal en la industria, hacen necesario que se controle el impacto negativo de sus acciones tanto en la salud de los seres humanos como en el ambiente.

ABSTRACT

Regarding the Brazilian textile industry, part of the northeast region stands out as the second-largest textile manufacturing hub in the country. Despite its importance, this industrial activity has been bringing relevant environmental concerns regarding the disposal of textile effluents, especially from industrial laundries. This waste contains many chemicals and among them are various types of heavy metals. To assess environmental risks associated with heavy metals, pollutant transfer needs to be investigated. This study evaluated the retention and mobility of heavy metals Cd and Cu in alluvial soil, through soil column tests. The up-flow column percolation tests were performed using a nonreactive tracer (KBr) at a concentration of 0.3 mol L
-1
and injecting a metallic solution containing Cu and Cd at 100 and 60 mg L
-1
, respectively. The injection flow rate was 0.75 mL min
-1
. The hydro-dispersive parameters were obtained by modeling the observed breakthrough curves with the convection-dispersion equation (CDE) and the two-region model, also referred to as the MIM (Mobile-IMmobile waters) model. The transport parameters were obtained from the two-site model (TSS). All elution curves were fitted to the models with the CXTFIT 2.0 program. The Two-Site Sorption Model was the best for the case studied, with R
2
of 0.985 and 0.995 for Cu and Cd, respectively. The values of R were considerably higher than the unit, presenting an average of 2.138 for Cu and 1.907 for Cd. This indicates a delay of these contaminants when leaving the column, which is caused by the interaction of these chemical compounds with the soil. The values obtained for parameter D were 3.469 for Cu and 5.205 for Cd. Thus, the metals in this study present a risk of groundwater contamination for the local alluvial aquifers. The main reason for that is the physicochemical features of the soil, such as high sand content (85 %) and low OM content (2.1 %). The results also indicated greater retention and less mobility for Cu than for Cd, pointing to a greater risk for Cd.

Introduction & Aim: Physical changes in the elderly include the musculoskeletal system, where there is a decrease in the production of synovial fluid as a joint lubricant causing impaired joint movement. Joint disorders are characterized by symptoms of joint stiffness or pain when moving. So far, activities at the elderly integrated service post (posyandu) include promotive and preventive activities. Still, the material presented has not shown any screening or early detection of joint stiffness due to osteoarthritis, even though many elderly people complain of joint stiffness and pain. Therefore, the purpose of this community service activity is to make the elderly remain active independently (LAMAR) to detect early symptoms of osteoarthritis using a goniometer. Method of Activity: This community service activity was carried out in February 2023 in the RW 7 area, Kapasan Village, Simokerto District, Surabaya City. The activity begins with an initial assessment of the elderly who are members of the elderly posyandu in the area. The activities carried out included the initial socialization of the LAMAR program, implementation of counseling, conducting early detection demonstrations, and program evaluation. The results of the screening were then processed using computer software. Results: The knowledge of the elderly after being given counseling on the Independent Active Elderly program through the media of booklets, power points, and goniometer teaching aids has been shown to increase where the statistical test results were p = 0.002 (α≤0.05) from 48% of respondents with sufficient and insufficient knowledge to 100% with a good level of knowledge. Discussion: The LAMAR (Independent Active Elderly) program will make the elderly productive, namely the elderly who are physically, mentally, and socially healthy. This can increase awareness/attention to the elderly in early detection of joint stiffness. The goniometer is used to measure and record the amount of joint movement actively or passively.

Published: October 2023

Background: Langerhans cell histiocytosis (LCH) is a rare hematological malignancy. The incidence of this disease is only 1% of soft tissue and lymph node cancer. Clinical manifestations and organ involvement vary widely. Lesions in the oral cavity are rare. LCH occurs more often in children, 10 times more often than in young adults.
Case presentation: A 20-year-old male came with the main complaint of a lump on the roof of the mouth and the right inner cheek. Physical examination of the face and oral cavity found a mass attached to the palate 1x1x1 cm with the same color as the surrounding tissue, flat surface, soft consistency, could be moved, and a mass was found in the left buccal 2x2x2 cm, with the same color as the surrounding tissue, flat surface, cystic consistency, not fixed and can be moved. Hematology laboratory examination was within normal limits, so no examination was carried out for bone marrow puncture (BMP). From the results of a CT scan of the head and neck, a solid mass was found with a hypodense part in it in the right buccal area attached to m. right masseter, and in the left hard palate area, which was suggestive of Langerhans cell histiocytosis. The results of histopathological examination of the lesion which underwent an incisional biopsy showed positive S100 and CD1a, this patient was diagnosed with Langerhans cell histiocytosis LCH. Next, this patient was treated with excision of the mass in the palate and buccal area. The patient was treated in the surgical inpatient department for 2 days, and the postoperative wound was in good condition.
Conclusion: Cases of Langerhans cell histiocytosis (LCH) are very rare cases that have different clinical symptoms depending on the organs involved, so it is important to understand this disease better. In this case, it was unilocal LCH without the involvement of other organs, so only local therapy was carried out in the form of surgical excision and observation was carried out after 3 months after surgery with the results of the wound improving without any new lumps appearing.

Prägnanz in visual perception
Authors: Van Geert Eline , Wagemans Johan 
Published: October 2023

AbstractHow do we perceptually and cognitively organize incoming stimulation? A century ago, Gestalt psychologists posited the law of Prägnanz: psychological organization will always be as ‘good’ as possible given the prevailing conditions. To make the Prägnanz law a useful statement, it needs to be specified further (a) what a ‘good’ psychological organization entails, (b) how the Prägnanz tendency can be realized, and (c) which conditions need to be taken into account. Although the Gestalt school did provide answers to these questions, modern-day mentions of Prägnanz or good Gestalt often lack these clarifications. The concept of Prägnanz has been (mis)understood in many different ways, and by looking back on the rich history of the concept, we will attempt to present a more fine-grained view and promote a renewed understanding of the central role of Prägnanz in visual perception and beyond. We review Gestalt psychology’s answers to the questions listed above, and also discuss the four main uses of the Prägnanz concept in more detail: (a) a Prägnanz tendency in each organizational process, (b) Prägnanz as a property of a Gestalt, (c) Prägnanz steps as internal reference points, and (d) Prägnanz in relation to aesthetic appreciation. As a key takeaway, Prägnanz is a multifaceted Gestalt psychological concept indicating the “goodness” of an experienced organization. Both the removal of unnecessary details and the emphasis on characteristic features of the overall organization compared to a reference organization can contribute to the emergence of a ‘better’ Gestalt. The stimulus constellation is not the only factor in determining the goodness of an organization, also the stimulus’ interaction with an individual in a specific spatial and temporal context plays a role. Taking the ideas on Prägnanz as a generative framework and keeping the original Gestalt psychological context in mind, future research on perceptual organization can improve our understanding of the principles underlying psychological organization by further specifying how different organizational principles interact in concrete situations. Public significance statement: This paper reviews what a ‘good’ psychological organization entails, and how the incoming stimulation is clarified in human perception to achieve the best possible psychological organization. The review debunks common misconceptions on the meaning of “goodness” and synthesizes the most important perspectives and developments on “goodness” from its conception until now.

El objetivo de este trabajo es determinar la presencia de Síndrome de Burnout en docentes universitarios de enfermería de la ciudad de Quito Ecuador y si existe una correlación con la edad o los años de servicio. Para este fin se utilizó como instrumento el Maslach Burnout Inventory con la participación de 26 docentes de la carrera de enfermería de diferentes universidades. Se logró identificar que el 17% de la población analizada presenta Síndrome de Burnout y el 30 % presenta un alto riesgo de desarrollar este síndrome, además, no se encontró estadísticamente una correlación significativa entre edad o años de servicio y las tres dimensiones del síndrome de agotamiento profesional (SAP). Es necesario hacer frente a esta afección que va en ascenso, implementar políticas de prevención tangible, además de un abordaje precoz.
Le corps sauvé : la conversion au végétarisme autour de 1900 et aujourd’hui
Authors: Atkinson Louise 
Published: October 2023

Cet article a pour point de départ des récits autobiographiques racontant des conversions au végétarisme, publiés entre 1896 et 1929 dans des revues d’associations affiliées à la Lebensreform allemande. Après avoir apporté des éléments de définition du récit de conversion dans le milieu alternatif allemand autour de 1900, nous examinons les similitudes et les disparités entre ces écrits et des récits autobiographiques de conversion publiés sur les réseaux sociaux numériques aujourd’hui. La question de fond est celle d’éventuelles continuités entre le végétarisme dans la scène alternative allemande des années 1900 et celui promu (dans le contexte du « bio-boom ») par des influenceuses allemandes contemporaines. Il apparaît que certains éléments fondamentaux – la structure narrative, la vision de la médecine conventionnelle, le paradigme de la bonté de la nature – traversent le siècle, bien qu’ils se manifestent de manière différente selon le contexte historique.
Les impasses de la sociogénomique
Authors: Robette Nicolas 
Published: October 2023

À partir des années 2000, les technologies de séquençage et de génotypage à haut débit se développent très rapidement. On peut dès lors étudier simultanément un grand nombre de marqueurs génétiques chez un grand nombre de sujets, ce qui permet l’apparition des « études d’associations pangénomiques » et des « scores de risques polygénique ». C’est dans ce contexte de progrès technologiques et statistiques que la « sociogénomique » – entendue comme la combinaison de la sociologie et de la génétique – apparaît et se diffuse dans le champ des sciences sociales. Or les méthodes utilisées par les sociogénomistes reposent sur un certain nombre de présupposés conceptuels et statistiques, dont la validité pose problème. Indépendamment des limites des outils utilisés, il apparaît que, à l’heure actuelle, les travaux de sociogénomique n’apportent qu’une faible contribution à la connaissance sociologique et démographique. On est le plus souvent en présence d’un acte de foi dans le progrès de la sociogénomique par l’intermédiaire des progrès techniques, sans remise en cause du modèle biologique sur lequel tout repose. De ce point de vue, l’écho des divers appels à la prudence des sociétés savantes en génétique humaine ne semble pas (encore) avoir porté jusqu’à ces « entrepreneurs de génétique » en sciences sociales.
Change in the community structure and organic carbon content of meio- and macrobenthos between tidal flat and salt marsh areas colonized by Spartina alterniflora in the Bahía Blanca estuary (SW Atlantic)
Authors: Reyna Gandini Leandro J. , Funk Flavia A. , Pratolongo Paula D. 
Published: October 2023

Salt marshes are regarded as among the most productive coastal ecosystems, important “blue carbon” sinks and a support for benthic communities with large abundances, whose structure may be strongly influenced by salt marsh vegetation. During the last few decades, Spartina alterniflora has been colonizing bare mudflats in the Bahía Blanca estuary, and a large increase in the area covered by salt marshes has been reported. This colonization can strongly influence the structure of benthic fauna and its role in the carbon cycle. The hypothesis of this study was that the community structure and the organic carbon contained in the meio- and macrobenthos change between tidal flats and salt marshes recently colonized by S. alterniflora. Response variables studied to compare the tidal flat and salt marsh were density, biomass and production to biomass (P/B) ratio of macro- and meiobenthos. Density and biomass of Gastropoda and P/B ratio of Nematoda were higher on the salt marsh than on the tidal flat. By contrast, density and biomass of Polychaeta were higher on the tidal flat. These results suggest that the expansion of S. alterniflora marshes on tidal flats produces changes in the structure of the macro- and meiobenthos community (taxonomic composition and biomass) that have an influence on carbon cycling.
Paradoxical reaction in peripheral lymph node tuberculosis: a review for its prevalence, clinical characteristics, and possible treatment
Authors: Rai Deependra Kumar , Kant Surya , Gupta Vatsal Bhushan 
Published: October 2023

The paradoxical reaction (PR) is a transient worsening following tuberculosis treatment and it is not uncommon in lymph node tuberculosis (LNTB). PR in LNTB maybe wrongly considered as treatment failure or relapse. This review was undertaken to address various aspects of PR associated with lymph node tuberculosis prevalence, underlying mechanism, clinical pattern, predictors, and possible treatment in an immunocompetent individual. A literature review was performed using various databases (PubMed, Scopus, Science Direct, and Google Scholar) to identify relevant articles for review. The prevalence of paradoxical reactions associated with LNTB varies from as low as 13.3% to as high as 35.3% PR may occur during antitubercular treatment or be reported even after completion of treatment called post-therapy PR. An onset of PR may occur within a month of therapy to even 12 months from the initiation of an anti-tubercular drug. Delayed hypersensitivity reaction and reduction in immune suppression is believed to be possible mechanism leading to a paradoxical reaction. PR in LNTB is characterized by either progression of pre-existing nodal enlargement or formation of abscess, sinus formation, or appearance of new nodal enlargement or rarely extra-nodal involvement. PR is a diagnosis of exclusion and may show granuloma, positive AFB smear, or positive GeneXpert but AFB culture is always negative. Younger age, lymph node size of equal to or more than 3 cm, female gender, unilateral lymphadenopathy, and those with positive AFB on initial examination are predictors for PR in peripheral LNTB. The majority of PR in LNTB have a mild course and are generally self-limited.
