Preguntas hacia la comunalización de lo público a nivel local como desafío para las alternativas a lo manicomial

Este artículo se centra en algunos resultados de una investigación que tuvo por objetivo estudiar los sentidos que algunos colectivos construyen en relación a su accionar en una zona particular de la periferia urbana de Montevideo, Uruguay. Se hizo énfasis en aquellos sentidos sobre sus vínculos con agentes estatales y sus estrategias para construir autonomía. Uno de los resultados es la búsqueda de hacer común lo público, incorporar a las lógicas de la producción de lo común para la sostenibilidad de la vida recursos que son administrados por el Estado. Estos procesos de comunalización aportan a la implementación de alternativas al encierro en tanto los sentidos construidos en torno a ellos justamente se vinculan a prácticas y creación de políticas públicas ligadas a estas alternativas. Asimismo, se apuesta a procesos de autonomía, participación y emancipación social. En la discusión profundizo en algunas dimensiones de la comunalización de lo público en el caso de un espacio de trabajo permanente interinstitucional, promovido por una de las organizaciones que formó parte de dicho estudio, que trabaja en la zona en clave de desmanicomialización y podría pensarse que también en relación con la economía social y solidaria. Estas dimensiones son: el carácter del entramado, las transformaciones normativas e institucionales y las articulaciones entre el paradigma de lo común y el de la desmanicomialización y la economía social y solidaria. Quedan planteadas tanto estas dimensiones como múltiples preguntas para seguir profundizando en esta línea.

Este artigo enfoca alguns resultados de uma pesquisa que teve como objetivo estudar os significados que alguns grupos de uma determinada área da periferia urbana de Montevidéu, Uruguai, constroem em relação às suas ações, com ênfase naqueles sobre seus vínculos com agentes estatais .e suas estratégias de construção de autonomia. Um dos resultados é a busca de tornar o público comum, incorporar na lógica da produção do comum para a sustentabilidade da vida recursos que são administrados pelo Estado. Isso contribui para a implementação de alternativas ao encarceramento na medida em que os próprios protagonistas lhe dão o sentido de trabalhar em práticas e para a criação de políticas públicas que os favoreçam e para processos de autonomia, participação e emancipação social. Na discussão aprofundo algumas dimensões da comunalização do público no caso de um espaço de trabalho interinstitucional permanente promovido por uma das organizações que estudei que atua na área em termos de desinstitucionalização e em relação ao social e economia solidária. Essas dimensões são: a natureza do enquadramento, as transformações normativas e institucionais e as articulações entre o paradigma do comum e o da desinstitucionalização e da economia social e solidária. Ambas as dimensões e múltiplas questões são levantadas para continuar aprofundando nesta linha.

This article focuses on some results of a research that aimed to study the meanings that some groups in a particular area of the urban periphery of Montevideo, Uruguay, construct in relation to their actions, with emphasis on those about their links with state agents and their strategies to build autonomy. One of the results is the search to make the public common, to incorporate into the logic of the production of the common for the sustainability of life resources that are administered by the State. This contributes to the implementation of alternatives to confinement insofar as the protagonists themselves give it the sense of working in practices and for the creation of public policies that favor them and for processes of autonomy, participation and social emancipation. In the discussion, I delve into some dimensions of the communalization of the public in the case of a permanent inter-institutional work space promoted by one of the organizations that I studied that works in the area in terms of deinstitutionalization and in relation to the social and solidarity economy. These dimensions are: the nature of the framework, the normative and institutional transformations and the articulations between the paradigm of the common and that of deinstitutionalization and the social and solidarity economy. Both these dimensions and multiple questions are raised to continue deepening in this line.

Effect of Inoculum Size and Age, and Sucrose Concentration on Cell Growth to Promote Metabolites Production in Cultured Taraxacum officinale (Weber) Cells.

Pentacyclic triterpenes, including lupeol, α- amyrin, and ß-amyrin, present a large range of biological activities including anti-inflammatory, anti-cancer, and gastroprotective properties. The phytochemistry of dandelion (Taraxacum officinale) tissues has been widely described. Plant biotechnology offers an alternative for secondary metabolite production and several active plant ingredients are already synthesized through in vitro cultures. This study aimed to establish a suitable protocol for cell growth and to determine the accumulation of α-amyrin and lupeol in cell suspension cultures of T. officinale under different culture conditions. To this end, inoculum density (0.2% to 8% (w/v)), inoculum age (2- to 10-week-old), and carbon source concentration (1%, 2.3%, 3.2%, and 5.5% (w/v)) were investigated. Hypocotyl explants of T. officinale were used for callus induction. Age, size, and sucrose concentrations were statistically significant in cell growth (fresh and dry weight), cell quality (aggregation, differentiation, viability), and triterpenes yield. The best conditions for establishing a suspension culture were achieved by using a 6-week-old callus at 4% (w/v) and 1% (w/v) of sucrose concentration. Results indicate that 0.04 (±0.02) α-amyrin and 0.03 (±0.01) mg/g lupeol can be obtained in suspension culture under these starting conditions at the 8th week of culture. The results of the present study provide a backdrop for future studies in which an elicitor could be incorporated to increase the large-scale production of α-amyrin and lupeol from T. officinale.

Horn-shaped" deformity of the Occlutech®-PDA device: case report / [Deformidad en "forma de claxon" del dispositivo Occlutech-PDA.]

Background: The phenomenon of deformation of devices for closure of intracardiac defects in catheterization has been reported, but not of devices for closure of patent ductus arteriosus. Objective: to report a case of deformation of a relatively new type of device for closure of patent ductus arteriosus. Methods: report an adult with hypertensive patent ductus arteriosus and a positive balloon occlusion test will be presented, in whom the occlusion was attempted with an Occlutech®-PDA device. Results: Upon delivery, the device took the shape of a "horn" instead of a "champagne cork" (usual appearance), so it was extracted prior to it is release and the procedure was carried out with another device. Conclusion: To our knowledge, no deformation during the delivery transcatheter of the Occlutech®-PDA device has been published. Adverse events related to new technologies, as in our case, should be reported as soon as possible, since it can help manufacturers to improve their quality and provide greater safety to patients.

Introducción: Existen comunicados sobre el fenómeno de la deformación de dispositivos oclusores de defectos intracardíacos durante el cateterismo, pero no acerca de los dispositivos oclusores para el conducto arterioso persistente. Objetivo: comunicar un caso de deformación de un relativamente nuevo tipo de dispositivo oclusor de conducto arterioso persistente. Método: se presenta un paciente adulto con conducto arterioso persistente hipertensivo y prueba de oclusión con balón positiva, en quien se intentó ocluirle con un dispositivo Occlutech®-PDA. Resultado: al momento de la entrega, el dispositivo adoptó la "forma de claxon" en lugar de "corcho de champagne" (apariencia habitual), motivo por el que fue retirado previo a su liberación y el procedimiento fue llevado a cabo con otro dispositivo. Conclusión: hasta donde conocemos, no hay comunicados acerca de deformación del dispositivo Occlutech®-PDA durante su implante mediante cateterismo. Los eventos adversos relacionados a nuevas tecnologías, como el presentado en este caso, deben ser comunicados tan pronto como sea posible, ya que esto puede ayudar a los fabricantes a mejorar su calidad y proveer mayor seguridad a los pacientes.

Amelogenin in calcified matrices of odontogenic cysts and odontogenic tumors: An immunohistochemical study.

BACKGROUND/PURPOSE: There are few studies comparing the expression of enamel proteins, such as amelogenin, and cytokeratins in cyst and odontogenic tumors like in ameloblastoma and odontogenic keratocyst, indicating that amelogenin could be a potential biomarker for the aggressiveness in the odontogenic tumors. The aim of this study was to evaluate if the expression of amelogenin, cytokeratin AE1/AE3 (CKAE1/AE3) and cytokeratin 14 (CK14) in cysts and odontogenic tumors with calcified matrices such as calcifying odontogenic cyst (COC), compound (CdO) and complex (CxO) odontomas, adenomatoid odontogenic tumor (AOT) and calcifying epithelial odontogenic tumor (CEOT) as an aggressiveness indicator. MATERIALS AND METHODS: Three COC, eight CxO, three CdO, twelve AOT, two CEOT and three dental germs were submitted to an immunohistochemistry panel of antibodies composed of amelogenin, CKAE1/AE3 and CK14. RESULTS: CKAE1/AE3 and CK14 was present in all odontogenic epithelia. The amelogenin protein was detected in prismatic and amorphous calcified matrices of epithelial origin belonging to CxO, CdO, AOT, COC and the tooth germs used as controls. On the other hand, the CEOT was the only tumor or cyst studied that did not present immunostaining for amelogenin in calcified matrices. CONCLUSION: Amelogenin was detected in pathologies with a low or absent recurrence rate and excellent prognosis. CEOT was the lesion of greater clinical aggressiveness which did not express amelogenin. The presence of amelogenin in calcified matrices of odontogenic arise could be an indicator of low aggressiveness.

Negative Transmission of SARS-CoV-2 to Hand-Expressed Colostrum from SARS-CoV-2-Positive Mothers.

Aim: The objective of our study was to determine whether the SARS-CoV-2-positive mothers transmit the virus to their hand-expressed colostrum. Methods: This is an observational prospective study that included pregnant women who tested positive for SARS-CoV-2 by PCR test on a nasopharyngeal swab at the moment of childbirth and who wanted to breastfeed their newborns. A colostrum sample was obtained from the mothers by manual self-extraction. To collect the samples, the mothers wore surgical masks, washed their hands with an 85% alcohol-based gel, and washed their breast with gauze that was saturated with soap and water. Results: We obtained seven colostrum samples from different mothers in the first hours postdelivery. SARS-CoV-2 was not detected in any of the colostrum samples obtained in our study. Conclusion: In our study, breast milk was not a source of SARS-CoV-2 transmission. Hand expression (assuring that a mask is used and that appropriate hygienic measures are used for the hands and the breast), when direct breastfeeding is not possible, appears to be a safe way of feeding newborns of mothers with COVID-19.

The Prevalence of Rheumatoid Arthritis in Chile: A Nationwide Study Performed as Part of the National Health Survey.

OBJECTIVE: Genetic and environmental backgrounds influence the development of rheumatoid arthritis (RA). In Latin America, epidemiologic data are scarce. We aimed to determine the prevalence of RA in Chile in a population-based study. METHODS: The National Health Survey was a cross-sectional household survey with a stratified multistage probability sample of 6233 participants performed between August 2016 and March 2017. A screening instrument for RA was applied to a random sample of 3847 subjects > 30 years old. Positive screening was defined by at least 1 of the following: 2 swollen joints for at least 4 consecutive weeks (past/present), and/or a diagnosis of arthritis in the past. Individuals with positive screening had rheumatoid factor, anticitrullinated protein antibodies, and C-reactive protein measured, as well as clinical examination performed by a rheumatologist. Self-report of doctor-diagnosed RA was also performed. RESULTS: The screening questionnaire was applied to 2998 subjects. A positive screening was found for 783 (22.1%). Among subjects with positive screening, 493 (66%) had a clinical evaluation performed by a rheumatologist. Using the American College of Rheumatology/European League Against Rheumatism 2010 classification criteria, prevalence was 0.6% (95% CI 0.3-1.2). Prevalence was higher in women, and 3.3% of subjects self-reported having RA. CONCLUSION: According to this national population-based study, RA prevalence in Chile is 0.6% (0.3-1.2), a value similar to what has been found in developed countries and slightly lower than some Latin American countries. Self-reporting leads to overestimating RA.

Kinetics and modeling of cell growth for potential anthocyanin induction in cultures of Taraxacum officinale G.H. Weber ex Wiggers (Dandelion) in vitro

Background: Taraxacum officinale G.H. Weber ex Wiggers is a wild plant used in folk medicine to treat several diseases owing to bioactive secondary metabolites present in its tissue. The accumulation of such molecules in plant cells can occur as a response against abiotic stress, but these metabolites are often deposited in low concentrations. For this reason, the use of a biotechnological approach to improve the yields of technologically interesting bioactive compounds such as anthocyanins is a compelling option. This work focuses on investigating the potential of in vitro T. officinale cultures as an anthocyanin source. Results: To demonstrate the suitability of anthocyanin induction and accumulation in calluses under specific conditions, anthocyanin was induced in the T. officinale callus. A specific medium of 5.5% sucrose supplemented with 6-benzylaminopurine /1-naphthaleneacetic acid in a 10:1 ratio was used to produce an anthocyanin yield of 1.23 mg g-1 fw. An in vitro dandelion callus line was established from this experiment. Five mathematical models were then used to objectively and predictably explain the growth of anthocyanin-induced calluses from T. officinale. Of these models, the Richards model offered the most suitable representation of anthocyanin callus growth in a solid medium and permitted the calculation of the corresponding kinetic parameters. Conclusions: The findings demonstrate the potential of an in vitro anthocyanin-induced callus line from T. officinale as an industrial anthocyanin source.

Educational website incorporating rheumatoid arthritis patient needs for Latin American and Caribbean countries.

Health education is fundamental in the management of RA patients. This study explored patient needs for educational material appropriate for RA patients in our region through a website. This study includes seven focus groups and semi-structured interviews across 4 countries (Argentina, Chile, Colombia, and Mexico) with 71 RA patients. Transcripts were analyzed by anthropologists using qualitative analysis (QA), resulting in themes and subthemes to be developed. Five themes and over 50 subthemes of interest were identified by patients. Grouped into categories as follows: (1) knowing the disease, (2) living with arthritis, (3) treatment and therapies for RA, (4) psychosocial support, and (5) information for families. A response was written by the team in plain Spanish on patient subthemes of interest including additional areas that the team considered relevant. Three videos for YouTube were produced: on patient-doctor relationships, patients at work, and home and at the clinic. Illustrations in a comic book format on RA diagnosis were created. The educational site on RA of PANLAR can be found at htpp://artritisreumatoide.cl. This project accomplished a comprehensive list of RA patient interests, revealing the complex relationship between the information on the disease, the experience of a chronic disease, and the way in which patients approach, conceive, and manage their disease. We expect to gather information on how the website will be used in the future for patients and their families and maintain and improve the website as well as adapt its content to different socioeconomic realities.

[The perception of values in food commercials on the part of young people with and without eating disorders]. / Valores percibidos en la publicidad de alimentos por jóvenes con y sin trastornos de la conducta alimentaria.

Advertising uses stereotyped body images to promote physical ideals and unhealthy eating habits related to food products which are targeted especially at young people. The purpose of this study, carried out in Barcelona (Spain) in May 2013, was to test the perception of 139 young people of university age - with and without eating disorders - regarding 25 values in seven food commercials that did and did not use body image strategies. Results show that only the group of young people with eating disorders considered commercials using body image strategies to have a very negative influence on values such as health, well-being, family and effort. In contrast, the assessment of the two groups regarding the rest of the commercials greatly coincided. These results show that today’s university youth have accepted as normal a beauty canon based on the prevailing social and economic order, while young people in treatment for eating disorders have learned to denaturalize such messages.

Valores percibidos en la publicidad de alimentos por jóvenes con y sin trastornos de la conducta alimentaria / The perception of values in food commercials on the part of young people with and without eating disorders

La publicidad utiliza imágenes corporales fuertemente estereotipadas para promocionar cánones físicos y conductas alimentarias no saludables asociadas a productos de alimentación dirigidos sobre todo a jóvenes. El objetivo de este estudio, realizado en Barcelona (España) durante el mes de mayo de 2013, es testear la percepción de 25 valores en siete spots televisivos de alimentación (con y sin estrategias de imagen corporal) en 139 jóvenes con y sin trastornos de la conducta alimentaria (TCA). Los resultados muestran que solo el grupo de jóvenes con TCA considera que los spots con una estrategia comercial basada en la imagen corporal influyen muy negativamente en valores como salud, bienestar, familia y esfuerzo. En cambio, se ha observado una gran coincidencia entre los dos grupos cuando se evalúa el resto de los spots. Estos resultados señalan que los jóvenes universitarios españoles de hoy han aceptado como normal un canon de belleza basado en el orden social y económico, mientras que los jóvenes en tratamiento por desórdenes alimenticios sí han aprendido a decodificar este tipo de mensajes.

Hábito lesivo poco frecuente: presentación de un caso / An infrequent damaging habit: a case presentation

FUNDAMENTO: existen hábitos lesivos llamados neurosis, que se consideran factores importantes en el comienzo y evolución de la enfermedad periodontal. Ellos son capaces de influir tanto en su aparición y curso como en el resultado de su tratamiento. OBJETIVO: relatar un caso hábito poco frecuente en Estomatología. CASO CLÍNICO: se presenta el caso de una paciente de 27 años, con encías en el sector anteroinferior fuera de su posición debido a su hábito, desde la niñez, de morderse la uñas y empaquetarla en las encías de sus dientes anteroinferiores. Al examen físico se observó escasa placa dentobacteriana y presencia de sarro dentario, no caries dental, recesiones gingivales marcadas en sector anteroinferior con denudación de la superficie radicular. Se mostró un poco tímida, ansiosa, frustada. Se discutió el diagnóstico y manejo de esta enfermedad poco habitual. Se utilizó terapia sicológica y odontológica y se mantuvo una óptima higiene bucal por parte del paciente y vigilancia estricta del periodoncista. CONCLUSIONES: la paciente está en tratamiento con una evolución satisfactoria.

BACKGROUND: there are damaging habits called neurosis which are considered important factors in the beginning and evolution of the periodontal disease. These habits can influence its appearance and course, as well as the result of its treatment. OBJECTIVE: to present a case of an infrequent habit in Stomatology. CLINICAL CASE: the case of a twenty-seven-year-old patient is presented. The patient's gums, in the anteroinferior region, were out of position because of her habit since childhood of biting her nails and packing them on the gums of her anteroinferior teeth. A scarce dentobacterial plaque and the presence of tartar, as well as dental caries, gingival resections in the anteroposterior area with denudation of the radicular surface were observed in the physical examination. The patient was a little shy, impatient, frustrated. The diagnosis and handling of this infrequent disease was discussed. Psychological and odontological therapy was applied and an optimum oral hygiene was carried out by the patient and the periodontist made a strict vigilance. CONCLUSIONS: the patient is under treatment with a satisfactory evolution.

The enhancement of antioxidant compounds extracted from Thymus vulgaris using enzymes and the effect of extracting solvent.

We evaluate the total phenolic compounds (TPC) content and the antioxidant activity (AA) of extracts obtained from ground fresh thyme (FT) and depleted thyme (DT), a by-product of the process of essential oil extraction. In addition, enzymatic treatments were evaluated to improve the extraction yields of polyphenolic compounds from thyme. Extractions were performed using several solvents as methanol, ethanol, and water. Enzymes were applied prior to extraction or during the extraction process. The best results were obtained using a mixture of methanol and water, resulting in 2790 and 220 mg Gallic acid equivalent (GAE)/L of TPC for FT and DT, respectively. A similar result was observed for AA. With regard to enzymatic treatment, application of Grindamyl CA 150 enzyme as a pre-treatment resulted in the production of an extract from DT with 614 mg TE (trolox equivalent)/L of AA, 70% more than the control, and an AA of 621 mg TE/L (74% more than the control sample) was obtained using Grindamyl CA 150 during the extraction process. These results suggest that enzymatic treatment is an interesting alternative for producing antioxidant extracts from DT.
