Autoinflammatory diseases: a Latin American multicenter study according to age and sex / Doenças autoinflamatórias: um estudo multicêntrico latino-americano de acordo com o sexo e a idade

ABSTRACT Objective: To evaluate autoinflammatory diseases (AID) according to age at diagnosis and sex, and response to therapy in a large population. Methods: This is a cross-sectional observational study of a Latin American registry using a designed web system for data storage, collected between 2015 and 2018. Any altered findings during follow-up were recorded. The forms were translated into Portuguese and Spanish, including demographic, clinical, laboratory, genetic and treatment characteristics. Results: We included 152 patients, 51.3% male and 75% Caucasian. The median age at disease onset was 2.1 years (0-15.6 years) and median age at diagnosis 6.9 years (0-21.9 years); 111 (73%) were children (0-9 years old), and 41 (27%) were adolescents and young adults (AYA) (10-21 years old). Periodic fever, aphthous stomatitis, pharyngitis, and adenitis syndrome (PFAPA) occurred in 46/152 (30%), chronic non-bacterial osteomyelitis (CNO) in 32/152 (21%), and familial Mediterranean fever (FMF) in 24/152 (15.7%). PFAPA was significantly higher in young children than in AYA (38.7% vs. 7.3%, p<0.001), while CNO were lower (13.5% vs. 41.5%, p<0.001). The frequency of females was significantly higher in CNO (28.4% vs. 14.1%, p=0.031) and lower in FMF (8.1% vs. 23.1%, p=0.011). The most used drugs were glucocorticoids, non-steroidal anti-inflammatory drugs (NSAID), and colchicine. Glucocorticoids and colchicine treatment were used in all AID with good to moderate response. However, cryopyrin-associated periodic syndromes (CAPS) seemed unresponsive to glucocorticoids. NSAIDs and methotrexate were the main medications used to treat CNO. Conclusions: Differences among AID patients were observed in the LA population regarding sex and age at disease diagnosis.

RESUMO Objetivo: Avaliar as doenças autoinflamatórias (DAI) de acordo com sexo e idade no momento do diagnóstico e a resposta terapêutica em uma grande população. Métodos: Este é um estudo observacional transversal de um registro latino-americano que usou um sistema de dados coletados entre 2015 e 2018. Quaisquer achados alterados ao longo do acompanhamento foram registrados. Os formulários foram traduzidos para os idiomas português e espanhol, incluindo características demográficas, clínicas, laboratoriais, genéticas e de tratamento. Resultados: Incluímos 152 pacientes, sendo 51,3% do sexo masculino e 75% da raça branca. A média de idade de início da doença foi de 2,1 anos (0-15,6 anos) e a média de idade de diagnóstico 6,9 anos (0-21,9 anos); 111 (73%) eram crianças (0-9 anos) e 41 (27%) adolescentes/adultos jovens (10-21 anos). A síndrome de febre periódica, estomatite aftosa, faringite e adenite (PFAPA) ocorreu em 46/152 (30%), osteomielite não bacteriana crônica (CNO) em 32/152 (21%) e febre familiar do Mediterrâneo (FMF) em 24/152 (15,7%). A PFAPA foi significativamente maior em crianças pequenas (38,7 vs. 7,3%, p<0,001), e a CNO, em adolescentes/adultos jovens (13,5 vs. 41,5%, p<0,001). A frequência do sexo feminino foi significativamente maior na CNO (28,4 vs. 14,1%, p=0,031) e menor na FMF (8,1 vs. 23,1%, p=0,011). Os medicamentos mais utilizados foram glicocorticoides, anti-inflamatórios não esteroidais (AINE) e colchicina. O tratamento com glicocorticoides e colchicina foi usado em todas as DAI com resposta boa a moderada. No entanto, as síndromes periódicas associadas à criopirina (CAPS) pareciam não responder aos glicocorticoides. AINE e metotrexato foram os principais medicamentos utilizados no tratamento da CNO. Conclusões: Diferenças de pacientes com DAI foram observadas na população latino-americana em pacientes agrupados por sexo e idade ao diagnóstico da doença.

Comparative study of physical-chemical properties of bioactive glass ionomer cement

Abstract This study analyzed the physical-chemical properties of bioactive ionomer materials. Cention N bioactive materials were evaluated chemically activated (CN) and light-cured (CN-LC), Equia Forte Fill (EQUI); conventional resin composite Filtek Z350 XT (Z350); resin glass ionomer cement Riva light Cure (RIVA) and flowable resin composite Filtek Bulk Fill Flow (BULK-F) were evaluated. Sixty specimens (n=10) were prepared for sorption (SR), solubility (SL), flexural strength (FS), shrinkage stress (SS), conversion degree (CD), microhardness (MI), and surface roughness (SR) tests. Non-cured and light-cured materials were assessed on FTIR. 30 human molar teeth were used in the bond strength test (BS). Data were subjected to ANOVA and post-hoc Tukey's test (5% of significance). EQUI showed more sorption in SR and no statistical difference from RIVA and CN-LC. CN group showed more solubility and EQUI presented less (p<0.05). BULK-F showed higher FS (MPa), without differences from CN and Z350, whereas EQUI presented the lowest FS not differing from RIVA. BULK-F and CN-LC showed more shrinkage stress differing from EQUI. CN-LC and CN showed higher CD differing from the other which showed no differences (p>0.05) between them. EQUI showed the highest hardness (p<0.05) in MI. There were no differences (p>0.05) in SR (µm). Z350 and BULK-F presented higher BS, whereas CN-LC showed the lowest, although not differing from EQUI and RIVA. Equia Forte's solubility and microhardness make it a good alternative as a restorative material. Cention N degree of conversion and flexural strength making it an esthetic option to amalgam.

Effect of tobacco smoking on outcomes of trabeculectomy / Efeito do tabagismo nos desfechos da trabeculectomia

ABSTRACT Purpose: To evaluate the effect of tobacco smoking on trabeculectomy outcomes. Methods: Charts of patients with glaucoma who underwent trabeculectomy performed by a single surgeon between 2007 and 2016 were retrospectively reviewed. Charts were screened for a documented history of smoking status before surgery. Demographic and clinical preoperative variables were recorded. Based on smoking history, subjects were divided into two groups: smokers and nonsmokers. Any bleb-related interventions (e.g., 5-flourouracil injections ± laser suture lysis) or bleb revision performed during the postoperative period were noted. Success was defined as an intraocular pressure >5 mmHg and <21 mm Hg without (complete success) or with (qualified success) the use of ocular hypotensive medications. Failure was identified as a violation of the criteria mentioned above. Results: A total of 98 eyes from 83 subjects were included. The mean age of the subjects was 70.7 ± 11.09 years, and 53% (44/83) were female. The most common diagnosis was primary open-angle glaucoma in 47 cases (47.9%). The smokers Group included 30 eyes from 30 subjects. When compared with nonsmokers, smokers had a significantly worse preoperative best-corrected visual acuity (p=0.038), greater central corneal thickness (p=0.047), and higher preoperative intraocular pressure (p=0.011). The success rate of trabeculectomy surgery at 1 year was 56.7% in the smokers Group compared with 79.4% in the Group nonsmokers (p=0.020). Smoking presented an odds ratio for failure of 2.95 (95% confidence interval, 1.6-7.84). Conclusion: Smokers demonstrated a significantly lower success rate 1 year after trabeculectomy compared with nonsmokers and a higher requirement for bleb-related interventions.

RESUMO Objetivo: Avaliar o efeito do tabagismo nos desfechos da trabeculectomia. Métodos: Uma revisão retrospectiva do gráfico de pacientes com glaucoma submetidos à trabeculectomia foi realizada por um único cirurgião entre 2007 e 2016. Os gráficos foram examinados para uma história documentada de condição de fumante antes da cirurgia. Variáveis pré-operatórias clínicas e demográficas e clínicas foram registradas. Os pacientes foram divididos em dois grupos de acordo com sua história de tabagismo em fumantes e não fumantes. Quaisquer Intervenções relacionadas à bolha, por exemplo, injeções de 5-fluorouracil + lise de sutura com laser, ou revisão da bolha realizada durante o período pós-operatório foram observadas. O sucesso foi definido como pressão intraocular > 5 mmHg e < 21 mm Hg sem (sucesso completo) ou com (sucesso qualificado) medicamentos hipotensores oculares. A falha foi identificada como violação dos critérios mencionados acima. Resultados: O estudo incluiu 98 olhos de 83 pacientes com idade média de 70,7 ± 11,09 anos, sendo 53% (44/83) dos pacientes do sexo feminino. O diagnóstico mais comum foi o glaucoma de ângulo aberto primário com 47 casos (47,9%). O Grupo de fumantes incluiu 30 olhos de 30 pacientes. Os fumantes, quando comparados aos não fumantes, apresentaram uma melhor acuidade visual pré-operatória significativamente pior (p=0,038), maior espessura central da córnea (p=0,047) e maior pressão intraocular pré-operatória (p=0,011). A taxa de sucesso de um ano para a cirurgia de trabeculectomia foi de 56,7% no Grupo de fumantes contra 79,4% no Grupo de não fumantes (p=0,020). O tabagismo apresentou razão de chances para falha de 2,95 95% de IC (1,6-7,84). Conclusão: Os fumantes demonstraram uma taxa de sucesso significativamente menor em um ano após a trabeculectomia em comparação com os não fumantes e uma maior necessidade de intervenções relacionadas à bolha.

Evaluation of the participation of ABCA1 transporter in epicardial and mediastinal adipose tissue from patients with coronary artery disease

ABSTRACT Objective: Recent studies have shown a relationship between adipose tissue and coronary artery disease (CAD). The ABCA1 transporter regulates cellular cholesterol content and reverses cholesterol transport. The aim of this study was to determine the relationship between single nucleotide polymorphisms (SNPs) R230C, C-17G, and C-69T and their expression in epicardial and mediastinal adipose tissue in Mexican patients with CAD. Subjects and methods: The study included 71 patients with CAD and a control group consisting of 64 patients who underwent heart valve replacement. SNPs were determined using TaqMan probes. mRNA was extracted using TriPure Isolation from epicardial and mediastinal adipose tissue. Quantification and expression analyses were done using RT-qPCR. Results: R230C showed a higher frequency of the GG genotype in the CAD group (70.4%) than the control group (57.8%) [OR 0.34, 95% CI (0.14-0.82) p = 0.014]. Similarly, C-17G (rs2740483) showed a statistically significant difference in the CC genotype in the CAD group (63.3%) in comparison to the controls (28.1%) [OR 4.42, 95% CI (2.13-9.16), p = 0.001]. mRNA expression in SNP R230C showed statistically significant overexpression in the AA genotype compared to the GG genotype in CAD patients [11.01 (4.31-15.24) vs. 3.86 (2.47-12.50), p = 0.015]. Conclusion: The results suggest that the GG genotype of R230C and CC genotype of C-17G are strongly associated with the development of CAD in Mexican patients. In addition, under-expression of mRNA in the GG genotype in R230C is associated with patients undergoing revascularization.

Aim: This present study aims to compare the data from the Brazilian Unified Health System on the number of clinical consultations of Oral Medicine from the first 6 months (March-August 2020) of the COVID-19 pandemic in Brazil with the last 6 months (September-February 2020/2021) to update the data, verify the measures' effectiveness to return clinical activities in the following months. Methods: perform a literature review of recent articles that report the impact of the COVID-19 pandemic on Oral Medicine. Results: There was an increase in the number of Oral Medicine clinical consultations in the second half of the pandemic throughout Brazil (+64.2%), representing over 9,235 appointments in this period. Conclusion: measures for the return of health assistance and the practice of Telemedicine proved to be effective after the second period of the pandemic. Even so, strengthening security measures against the coronavirus is essential to ward off a new wave since the Omicron variant emerged in the country and, consequently, possible new lockdowns that might affect healthcare in Brazil

Obesidad y monocitos macrófagos en el tejido adiposo / Adipose tissue monocytes and macrophages in obesity

Introducción: el tejido adiposo ha sido objeto de estudio en las últimas décadas y existen nuevos conceptos de su compleja biología. Se conoce que la obesidad está asociada con un estado inflamatorio crónico de bajo grado tanto local como sistémico y parece desempeñar un papel clave en las consecuencias del aumento en diferentes comorbilidades metabólicas y vasculares. Discusión: de los diversos tipos de células inmunes que contribuyen a la inflamación inducida por la obesidad, los monocitos/macrófagos en el tejido adiposo juegan un papel central. Las modificaciones estructurales y fenotípicas de ambas células pueden contribuir no solo a alteraciones inflamatorias y metabólicas, sino también ayudar a mantener la homeostasis del tejido adiposo en respuesta al aumento de la grasa corporal. Los macrófagos son células efectoras esenciales en la organización de la inflamación, ya que se cree que promueven la progresión de la obesidad y los trastornos relacionados. No está completamente establecido si dichas células ejercen un papel beneficioso o nocivo en el tejido adiposo. En cualquier caso, su presencia modifica la biología de las células adiposas especializadas. Conclusiones: en esta revisión se analiza el conocimiento sobre la contribución de los monocitos/macrófagos dentro del tejido adiposo en el desarrollo y mantenimiento de la obesidad y las complicaciones potenciales relacionadas.

Objetivo: Avaliar a percepção e segurança dos cirurgiões-dentistas servidores municipais de Porto Alegre - RS que realizam radiografias intrabucais em relação à conteúdos da radiologia odontológica. Materiais e métodos: Todos os 26 dentistas que atuam no Centro de Especialidades Odontológicas e Serviço de Apoio Terapêutico da Secretaria Municipal de Saúde foram convidados a participar de 15 horas do Projeto de Extensão em Radiologia Odontológica da Faculdade de Odontologia da Universidade Federal do Rio Grande do Sul, onde alunos de graduação atendem pacientes encaminhados pelas unidades básicas de saúde. Foi aplicado um questionário online de 19 questões relacionado a sua segurança e rotina na Radiologia. Os dados coletados foram submetidos à análise descritiva. Dez profissionais participaram do projeto, e oito responderam ao questionário (n=8). Resultados: Realização de técnicas e processamentos radiográficos, a maioria dos participantes mostrou-se segura, assim como os aspectos de radioproteção. Relataram maior dificuldade em realizar exames radiográficos em criança, molares e caninos superiores, além de preferirem, o método manual visual de processamento radiográfico. Foi identificada menor compreensão sobre biossegurança e efeitos biológicos determinísticos. Discussão: Conhecer esses servidores, suas rotinas e vivências com a radiologia, permitiu aprimorar o atendimento aos pacientes e a integração da Faculdade ao programa de educação permanente. Observa-se que princípios teóricos, não estão sedimentados o que pode interferir tanto na sua saúde como na do paciente. Conclusão: Os profissionais estudados sentem-se seguros em relação à prática e compreendem suas lacunas de conhecimento sobre efeitos biológicos e biossegurança na área da Radiologia.

Aim: To evaluate the perception and confidence of dental surgeons working in Porto Alegre - RS who perform intraoral radiographs in relation to the contents of dental radiology. Materials and methods: All 26 dentists who work at the Center for Dental Specialties and Therapeutic Support Service of the Municipal Health Department were invited to participate in 15 hours of the Extension Project in Dental Radiology at the School of Dentistry at the Federal University of Rio Grande do Sul, where students Undergraduate courses assist patients referred by basic health units. An online questionnaire of 19 questions related to your safety and routine in Radiology was applied. The collected data were submitted to descriptive analysis. Ten professionals participated in the project, and eight answered the questionnaire (n=8). Results: Performing radiographic techniques and processing, most participants proved to be safe, as well as radioprotection aspects. They reported greater difficulty in performing radiographic examinations in children, molars and upper canines, in addition to preferring the visual manual method of radiographic processing. Less understanding of biosafety and deterministic biological effects was identified. Discussion: Getting to know these public servants, their routines and experiences with radiology, made it possible to improve patient care and integrate the Faculty into the permanent education program. It is observed that theoretical principles are not settled, which can interfere with both your health and that of the patient. Conclusion: The professionals studied feel safe and understand their knowledge gaps such as biological effects and biosafety in the field of Radiology.

Introducción: La oftalmopatía tiroidea (OT) es un trastorno debilitante en pacientes con enfermedad tiroidea autoinmune, principalmente enfermedad de Graves, que se desarrolla entre el 30 a 50% de los casos. Objetivos: Describir las características clínico-oftalmológicas y la evolución de los pacientes con oftalmopatía tiroidea activa moderada severa tratados con bolos de metilprednisolona que acuden al Hospital Central del Instituto de Previsión Social en el tiempo comprendido entre enero de 2018 y setiembre de 2021. Materiales y métodos: Investigación de diseño observacional, con estudio descriptivo, retrospectivo. Resultados: Se revisaron fichas de 34 pacientes con OT activa moderada severa que recibieron bolos de metilprednisolona basado en las guías EUGOGO 2016, de los cuáles se excluyeron 3 pacientes por tener fichas incompletas y otros 3 pacientes ya que requirieron tratamiento de segunda línea previo al término del esquema de 12 sesiones. De los 28 pacientes estudiados, la edad promedio fue de 43,6 ±13,1 años, el 89% de sexo femenino y el 28,5%, fumadores. En cuanto a la función tiroidea de la población previo al tratamiento, se constató hipertiroidismo en el 82%, hipotiroidismo en el 11% y eutiroidismo en el 7%; y posterior al tratamiento, se constató hipertiroidismo en el 78,6% (subclínico), eutiroidismo en el 17,9% e hipotiroidismo en el 3,5%. La mayoría (92.6%) contaba con anticuerpos contra el receptor de TSH positivo, con un promedio de 18 ± 9,9 mIU/Ml. Respecto a la actividad de la oftalmopatía según la escala CAS, se constató un promedio de 4,1 ±1,0 previo al tratamiento y posterior 1,2 ±1,4; de ellos el 46,4% presentó un estado leve según escala de gravedad, 39% sin criterios de gravedad y 14 % persistió en moderada -severa. Se constató mejoría de la agudeza visual tras el tratamiento (57,1%), el promedio de exoftalmía previo al tratamiento fue 22,2 mm y posterior 21,1 mm; se presentó diplopía en el 7,1% previo al tratamiento y en el 3,6% posterior al tratamiento. Conclusión: El tratamiento con glucocorticoides endovenosos en la oftalmopatía de Graves moderada-severa (esquema EUGOGO 2016) fue muy efectivo, revirtiendo la actividad y consecuentemente ayudando a disminuir la gravedad, en la gran mayoría de nuestros pacientes. Esto podría explicarse porque la oftalmopatía era incipiente y por el alto grado de adherencia de los pacientes en el contexto de un manejo multidisciplinar bien protocolizado.

The majority (92.6%) had positive thyrotropin receptor antibodies, with an average of 18 ± 9.9 mIU/Ml. Regarding the activity of orbitopathy according to the CAS scale, an average of 4.1 ±1.0 was found before treatment and 1.2 ±1.4 after; Of them, 46.4% presented a mild condition according to the severity scale, 39% without severity criteria and 14% persisted in moderate-severe. Improvement in visual acuity was noted after treatment (57.1%), the average exophthalmia before treatment was 22.2 mm and after 21.1 mm; Diplopia occurred in 7.1% before treatment and in 3.6% after treatment. Conclusion: Treatment with intravenous glucocorticoids in moderate-severe Graves' orbitopathy (EUGOGO 2016 scheme) was very effective, reversing the activity and consequently helping to reduce the severity, in the vast majority of our patients. This could be explained because the orbitopathy was incipient and by the high degree of patient adherence in the context of well-protocolized multidisciplinary management.

Los derechos sexuales y (no) reproductivos en suspenso en territorios rurales y urbanos de Santiago del Estero, Argentina / Sexual and (non) reproductive rights put on holdin rural and urban territories of Santiago del Estero, Argentina / Direitos sexuais e (não) reprodutivos suspensos nos territórios rurais e urbanos de Santiago del Estero, Argentina

Objetivo: analizar el acceso a derechos sexuales y (no) reproductivos de mujeres y niñas en el contexto de la pandemia por COVID-19; y las políticas implementadas (o no) por los gobiernos de la provincia de Santiago del Estero y nacional. Metodología: desde métodos cualitativos se ha indagado a través de entrevistas no estructuradas y en profundidad por medio de videollamadas por las plataformas disponibles: a funcionarias/os, agentes de salud y referentes de organizaciones sociales. Resultados: el acceso a los derechos sexuales y (no) reproductivos enfrentó graves dificultades entre las que podemos destacar las restricciones a la circulación, sobre todo durante el 2020, y la priorización en los servicios públicos a la atención de los casos de COVID-19. Las respuestas institucionales a las demandas de interrupciones legales de las niñas y mujeres embarazadas han seguido circuitos largos y laberínticos. Conclusión:los diversos obstáculos que enfrentan las mujeres y las niñas para que el Estado garantice sus derechos, deben situarse en la perduración de un contexto histórico y estructural, donde la sexualidad y la reproducción están sometidas a estricto control y el ejercicio de los derechos se enfrenta con morales restrictivas. Las respuestas ofrecidas por el Estado no fueron suficientes y las organizaciones sociales cumplieron un rol sustitutivo. Y allí en donde no hay una red de contención o una organización social, la vida de mujeres y niñas presenta mayor vulnerabilidad.

Objective: this study aims to assess the access to sexual and (non) reproductive rights of women and girls within the context of the COVID-19 pandemic, examining the policies implemented (or not) by the governments of Santiago del Estero province and nationally. Methods: utilizing qualitative approaches, the research conducted unstructured and in-depth interviews via video calls with officials, health agents, and representatives of social organizations.Results: Access to sexual and (non) reproductive rights encountered substantial challenges, notably movement restrictions, particularly in 2020, and the prioritization of public services for COVID-19 cases. Institutional responses to legal interruptions for pregnant girls and women involved complex and protracted procedures.Conclusion: the barriers faced by women and girls in obtaining state-guaranteed rights must be contextualized within a historical and structural framework, characterized by strict control over sexuality and reproduction. State responses proved insufficient, leading social organizations to assume a substitute role. In the absence of a support network or social organization, the vulnerability of women and girls is heightened.

Objetivo: analisar o acesso aos direitos sexuais e (não) reprodutivos de mulheres e meninas no contexto da pandemia da COVID-19 e as políticas implementadas (ou não) pelos governos da província de Santiago del Estero e a nível nacional. Metodologia: utilizando métodos qualitativos, a investigação foi realizada por meio de entrevistas não estruturadas e em profundidade por meio de videochamadas: a autoridades, agentes de saúde e representantes de organizações sociais. Resultados: o acesso aos direitos sexuais e (não) reprodutivos enfrentou sérias dificuldades, entre as quais podemos destacar as restrições à circulação, especialmente durante 2020, e a priorização dos serviços públicos para atendimento aos casos de COVID-19. As respostas institucionais às exigências de interrupções legais por parte de meninas e mulheres grávidas seguiram circuitos longos e labirínticos. Conclusão: os diversos obstáculos que as mulheres e as meninas enfrentam para que o Estado garanta os seus direitos devem ser colocados na continuidade de um contexto histórico e estrutural, onde a sexualidade e a reprodução estão sujeitas a um controle rigoroso e o exercício dos direitos enfrenta morais restritivas. As respostas oferecidas pelo Estado não foram suficientes e as organizações sociais desempenharam um papel substituto. E onde não existe rede de apoio ou organização social, as vidas das mulheres e das meninas são mais vulneráveis.

Neguentropia Algorítmica e a Gestão Digital do Gozo / Algorithmic Negentropy and the Digital Management of Jouissance / La Negentropia Algorítmica y la Gestión Digital del Goce

O algoritmo digital permitiu o manejo de dados dos usuários da web pelos conglomerados informacionais. De forma discreta e personalizada, a nova forma de governamentalidade coleta, organiza, permuta e devolve os dados ao próprio indivíduo na forma de mais informações. Cada vez mais, esbarra na dimensão singular, tocando o campo do gozo via proliferação de objetos a que, na teoria lacaniana dos discursos, assume a dupla função de perda e de incessante tentativa de suplementação de gozo. Com o incremento informacional, o objeto chega ao ápice social e o digital alcança patamar discursivo. Inserindo-se no mesmo nicho do saber, a informação digital se aproveita da divisão subjetiva, deixando pouco espaço para que o sujeito possa lidar com a entropia de seu gozo via desejo. Se a neguentropia é o atributo do saber que limita a dispersão de gozo, na informação tratada e retornada algoritmicamente tal processo sofre uma aceleração, agindo diretamente sobre a economia dos afetos. Com prejuízo para o sujeito, resta uma experiência de gozo cada vez mais direta, crua, menos mediatizada pelo saber e pelo Outro.

The digital algorithm has allowed the management of data from web users by informational conglomerates. In a discreet and personalized way, the new form of governmentality collects, organizes, exchanges and returns data to the individual in the form of more information. More and more, it comes up against the singular dimension, touching the field of jouissance via the proliferation of objects a which, in the Lacanian theory of discourses, assumes the double function of loss and an incessant attempt to supplement jouissance. With the increase in information, the object reaches the social apex and the digital reaches a discursive level. Inserting itself in the same niche of know [savoir], digital information takes advantage of the subjective division, leaving little space for the subject to deal with the entropy of his jouissance via desire. If negentropy is the attribute of savoir that limits the dispersion of jouissance, in the information processed and returned algorithmically this process is accelerated, acting directly on the economy of affections. To the detriment of the subject, what remains is an experience of jouissance that is increasingly direct, raw, less mediated by savoir and the Other.

Antitumor and immunomodulatory activity of fucoidan from the brown alga Lessonia trabeculata (Lessoniaceae) on breast cancer spheroids / Actividad antitumoral e inmunomoduladora de fucoidan del alga parda Lessonia trabeculata (Lessoniaceae) en esferoides de cáncer de mama

Abstract Introduction: The therapeutic benefits of the brown algae fucoidan in the treatment of breast cancer have attracted considerable interest in recent years. However, research using spheroids which provide relevant results in trials for antitumor and immunomodulatory products because they adequately simulate the tumor microenvironment, is limited. Objective: To evaluate the antitumor and immunomodulatory activity of Lessonia trabeculata fucoidan (LtF), native to the Peruvian Sea, on two types of multicellular tumor spheroids. Methods: The study was conducted from January to December 2021. Two types of spheroides were elaborated: from 4T1 tumor cells (MTS), and from 4T1 tumor cells+mouse splenocytes (MTSs). The antitumor activity of LtF was evaluated in MTS by quantifying cell viability with MTT. Immunomodulatory activity was determined in MTSs using the IC50 for two types of treatment: simple, fucoidan alone (LtF) and combined, fucoidan+doxorubicin (LtF+Dox). Pro-inflammatory (TNF-α, IL-6) and anti-inflammatory (IL-10, TGF-β) cytokine production was quantified by sandwich ELISA 72 h after treatment. Dox was used as positive control in all assays. Results: LtF exerted antitumor activity as evidenced by increased necrotic zone and cell debris formation compared to the untreated control. Antitumor activity was concentration dependent between 100 and 6 000 μg/ml. In MTSs, simple treatment increased IL-6 and decreased IL-10 and TGF-β production. The combined treatment significantly reduced TGF-β production. In both treatments and Dox, there was an increase in IL-6 compared to the untreated control. The highest production of IL-10 and TGF-β was observed in the untreated control, compatible with a highly immunosuppressive tumor microenvironment. Conclusions: LtF is a good candidate for the treatment of breast cancer and can immunomodulate the tumor microenvironment alone or in combination with Dox.

Resumen Introduccción: Los beneficios terapéuticos del fucoidan de algas pardas en el tratamiento del cáncer de mama han despertado gran interés en los últimos años. Sin embargo, las investigaciones con esferoides son limitadas, éstos proporcionan resultados relevantes en ensayos de productos antitumorales e inmunomoduladores porque simulan adecuadamente el microambiente tumoral. Objetivo: Evaluar la actividad antitumoral e inmunomoduladora del fucoidan de Lessonia trabeculata (LtF), nativa del Mar Peruano, en dos tipos de esferoides tumorales multicelulares. Métodos: El estudio se realizó de enero a diciembre de 2021. Se elaboraron dos tipos de esferoides: con células tumorales 4T1 (MTS) y con células tumorales 4T1+esplenocitos de ratón (MTSs). La actividad antitumoral de LtF se evaluó en MTS cuantificando la viabilidad celular con MTT. La inmunomodulación se determinó en MTSs utilizando la IC50 para dos tipos de tratamiento: simple, fucoidan solo (LtF) y combinado, fucoidan+doxorubicina (LtF+Dox). La producción de citoquinas proinflamatorias (TNF-α, IL-6) y antiinflamatorias (IL-10, TGF-β) se cuantificó mediante ELISA sándwich 72 h post-tratamiento. En todos los ensayos se utilizó Dox como control positivo. Resultados: En los MTS, el LtF ejerció actividad antitumoral evidenciada por aumento de la zona necrótica y formación de restos celulares respecto al control no tratado. La actividad antitumoral fue concentración-dependiente entre 100 y 6 000 μg/ml. En los MTSs, con el tratamiento simple se incrementó IL-6 y disminuyeron IL-10 y TGF-β. El tratamiento combinado redujo significativamente la producción de TGF-β. Los dos tratamientos y Dox incrementaron IL-6 respecto al control no tratado. La mayor producción de IL-10 y TGF-β se observó en los no tratados, compatible con un microambiente tumoral altamente inmunosupresor. Conclusiones: El LtF es un buen candidato para tratar el cáncer de mama y puede inmunomodular el microambiente tumoral solo o en combinación con Dox.

Análisis espacio-temporal de la tuberculosis pulmonar para el periodo 2016-2020 en la Región Metropolitana, Chile

Introducción: El año 2020, la tuberculosis (TB) fue responsable por 9,9 millones de nuevos casos y 1,5 millones de muertes en el mundo. En Chile, se ha reportado aumento en las tasas de incidencia en los últimos años, con gran concentración de casos en la Región Metropolitana (RM). Objetivo: Evaluar la relación espacio-temporal de la TB pulmonar con variables socioeconómicas en la RM de Chile. Material y Método: Estudio ecológico desarrollado entre los años 2016 y 2020. Los casos se obtuvieron desde el Ministerio de Salud (n = 4.370), describiéndose según: sexo, edad, año de confirmación diagnóstica, servicio de salud y comuna de residencia. Se utilizó análisis de componentes principales para la construcción de factores socioeconómicos comunales. La asociación entre factores y TB pulmonar se evaluó con un modelo binominal negativo multinivel. Resultados: Se observó aumento en la tasa de incidencia (9,97 a 10,74 casos por 100 mil), disminución de la incidencia en personas ≥ 65 años (17,56 a 13,38) y en el promedio de edad (46,03 a 41,77 años). El factor caracterizado por mayor inmigración, hacinamiento y población urbana se asoció con mayores tasas de incidencia (RTI: 1,29; IC95: 1,23-134) y el factor con mayor escolaridad, menor pobreza y menor hacinamiento con menores tasas (RTI: 0,94; IC95: 0,89-0,98) en el periodo. Conclusiones: La disminución en la edad de los casos junto a la concentración de casos en comunas urbanas y céntricas, asociadas con variables socioeconómicas desfavorables, confirman que la TB pulmonar continúa siendo un problema de relevancia a considerar.

Background: In 2020, tuberculosis (TB) was responsible for 9.9 million new cases and 1.5 million deaths worldwide. In Chile, an increase in incidence rates has been reported in recent years, with a concentration of cases in the Metropolitan Region (MR). Aim: To evaluate the spatio-temporal relationship of pulmonary TB with socioeconomic variables in the MR of Chile. Methods: Ecological study developed between 2016 and 2020. Cases were obtained from the Ministry of Health (n = 4,370) and described by: sex, age, year of confirmation, health service, and commune of residence. Principal component analysis was used to construct community socioeconomic factors, and the association between factors and pulmonary TB was evaluated with a multilevel negative binomial model. Results: There was an increase in the incidence rate (9.97 to 10.74 cases per 100,000), a decrease in the incidence in people ≥ 65 years (17.56 to 13.38), and the average age (46.03 to 41.77 years). The factor characterized by greater immigration, overcrowding, and the urban population was associated with more elevated incidence rates (RTI: 1.29; IC95: 1.23-134), and the factor with higher education, less poverty, and less overcrowding with lower rates (RTI: 0.94; CI 95: 0.89-0.98) in the period. Conclusions: The decrease in the age of the cases together and the concentration of cases in urban and central communes, associated with unfavorable socioeconomic variables, confirm that pulmonary TB continues to be a relevant problem to consider.

Leishmaniose Visceral Humana: monitoramento epidemiológico e indicadores de vida nos municípios da Bahia, Brasil / Human Visceral Leishmaniasis: epidemiological monitoring and life indicators in the municipalities of Bahia, Brazil

O comportamento dos indicadores de vida dos casos notificados de Leishmaniose Visceral (LV) na Bahia e fatores sociodemográficos foram analisados. Trata-se de um estudo analítico e retrospectivo (2010 a 2020) que utilizou dados secundários do SINAN/DATASUS. Foram analisados dados de notificações, incidência, transmissão, estratificação de risco e indicadores de vida. No período foram registrados 3.573 casos de LV, maior incidência de 3,52 casos/100 mil habitantes e transmissão esporádica na maioria dos municípios. A Taxa de Incremento Anual (TIA) no Núcleo Regional de Saúde Sul e Leste apresentou valores significativos para a incidência e, para a letalidade, na Oeste, Leste e Centro-Norte. O Disability Adjusted Life Years (DALY) demonstrou que a população baiana infectada perdeu 10 anos de vida. A análise de aspectos individuais dos municípios permitiu identificar a necessidade de implementação de políticas públicas efetivas nessa esfera administrativa.

The behavior of life indicators of notified cases of Visceral Leishmaniasis (VL) in Bahia and sociodemographic factors were analyzed. The study analyzes the behavior of life indicators of notified cases of Visceral Leishmaniasis (VL) in Bahia and its correlation with sociodemographic factors. This is an analytical and retrospective study (2010 - 2020) that used the SINAN/DATASUS secondary database between. Were analyzed data on notifications, incidence, transmission, risk stratification and life indicators. During the period there were 3,573 cases of VL, highest incidence of 3.52 cases/100,000 inhabitants and sporadic transmission in most municipalities. The Annual Increment Rate (AIR) in the South and East health macro-regions showed significant values for incidence and lethality in the West, East and Center-North regions. Disability Adjusted Life Years (DALY) showed that the infected Bahian population lost 10 years of life. The analysis of individual aspects of the municipalities made it possible to identify the need to implement effective public policies at this administrative level.

Patrones de actividad de mamíferos alrededor de la línea transportadora de gas natural de Camisea en la Reserva Comunal Machiguenga, Cusco, Perú

En el presente trabajo se estudia la actividad horaria de los mamíferos que habitan el área circundante a la línea transportadora de gas de Camisea que atraviesa la Reserva Comunal Machiguenga. Desde febrero del 2020 hasta enero del 2021, se realizó un registro fotográfico mediante cámaras trampa dispuestas a lo largo de la tubería de gas. Los patrones de actividad se estimaron mediante la función de densidad de Kernel. Durante el periodo de estudio, se registraron 25 especies de mamíferos. Se encontró que Dasyprocta kalinowskii y Eira barbara presentan un patrón de actividad diurno; mientras que Cuniculus paca, Tapirus terrestris, Dasypus spp. y Mazama spp. presentan un patrón predominantemente nocturno. Se sugiere que los patrones de actividad observados estarían influenciados por varios factores como la exclusión competitiva entre D. kalinowskii y C. paca, disponibilidad estacional del alimento para T. terrestris, variación de temperatura y precipitación para Dasypus spp., restricciones filogenéticas en Mazama spp., y segregación temporal con otros carnívoros para E. barbara. Se destaca la importancia de la colaboración entre las empresas del rubro energético, las comunidades nativas y las organizaciones gubernamentales.

The present study investigates the hourly activity patterns of mammals inhabiting the area surrounding the Camisea gas pipeline that crosses the Machiguenga Communal Reserve. From February 2020 to January 2021, a photographic record was conducted using camera traps placed along the gas pipeline. Activity patterns were estimated using Kernel density functions. During the study period, 25 mammal species were recorded. It was found that Dasyprocta kalinowskii and Eira barbara exhibit a diurnal activity pattern, whereas Cuniculus paca, Tapirus terrestris, Dasypus spp., and Mazama spp. display predominantly nocturnal behavior. It is suggested that observed activity patterns could be influenced by various factors such as competitive exclusion between D. kalinowskii and C. paca, seasonal food availability for T. terrestris, temperature and precipitation variations for Dasypus spp., phylogenetic constraints in Mazama spp., and temporal segregation with other carnivores for E. barbara. The significance of collaboration between energy industry companies, native communities, and governmental organizations is emphasized.

Frecuencia de eventos cardiovasculares en pacientes con lupus eritematoso sistémico / Frequency of cardiovascular events in patients with systemic lupus erythematosus

Resumen Introducción: el progreso en los tratamientos para el lupus eritematoso sistémico (LES) resultó en una disminución de la mortalidad; sin embargo, la enfermedad cardiovascular y las complicaciones infecciosas aún son las principales causas de muerte. La evidencia apoya la participación del sistema inmunológico en la generación de la placa aterosclerótica, así como su conexión con las enfermedades autoinmunes. Objetivos: describir la frecuencia de eventos cardiovasculares (ECV) en el Registro de Lupus Eritematoso Sistémico de la Sociedad Argentina de Reumatología (RELESSAR) transversal, así como sus principales factores de riesgo asociados. Materiales y métodos: estudio descriptivo y transversal para el cual se tomaron los pacientes ingresados en el registro RELESSAR transversal. Se describieron las variables sociodemográficas y clínicas, las comorbilidades, score de actividad y daño. ECV se definió como la presencia de al menos una de las siguientes patologías: enfermedad arterial periférica, cardiopatía isquémica o accidente cerebrovascular. El evento clasificado para el análisis fue aquel posterior al diagnóstico del LES. Se conformaron dos grupos macheados por edad y sexo 1:2. Resultados: 1515 pacientes mayores de 18 años participaron del registro. Se describieron 80 pacientes con ECV (5,3%). En este análisis se incluyeron 240 pacientes conformando dos grupos. La edad media fue de 47,8 (14,4) y 47,6 (14,2) en el grupo con y sin ECV respectivamente. Los pacientes con ECV tuvieron mayor duración del LES en meses, mayor índice de Charlson, mayor SLICC (Systemic Lupus International Collaborating Clinics/American College of Rheumatology), mayor frecuencia de manifestaciones neurológicas, síndrome antifosfolípido, hospitalizaciones y uso de ciclofosfamida. Las únicas variables asociadas en el análisis multivariado fueron el índice de Charlson (p=0,004) y el SLICC (p<0,001). Conclusiones: los ECV influyen significativamente en nuestros pacientes, y se asocian a mayor posibilidad de daño irreversible y comorbilidades.

Abstract Introduction: progress in treatments for systemic lupus erythematosus (SLE) has resulted in a decrease in mortality; however, cardiovascular and infectious diseases remain the leading causes of death. Evidence supports the involvement of the immune system in the generation of atherosclerotic plaque, as well as its connection to autoimmune diseases. Objectives: to describe the frequency of cardiovascular disease (CVD) in the cross-sectional RELESSAR registry, as well as its associated variables. Materials and methods: a descriptive and cross-sectional study was performed using patients admitted to the cross-sectional RELESSAR registry. Sociodemographic variables, clinical variables, comorbidities, activity and damage scores were described. CVD was defined as at least one of the following: peripheral arterial disease, ischemic heart disease, or cerebrovascular accident. All patients with at least one CVD were included in our analysis (heart attack, central nervous system vascular disease, and peripheral arteries atherosclerotic disease). The event classified for the analysis was that after the diagnosis of SLE. SLE diagnosis was previous to CVD. Two groups matched by age and sex, 1:2 were formed. Results: a total of 1515 patients older than 18 years participated in the registry. Eighty patients with CVD (5.3%) were described in the registry. Two-hundred and forty patients were included, according to two groups. The mean age was 47.8 (SD 14.4) and 47.6 (SD 14.2) in patients with and without CVD, respectively. Patients with CVD had a longer duration of SLE in months, a higher Charlson index, a higher SLICC, increased frequency of neurological manifestations, antiphospholipid syndrome, hospitalizations, and use of cyclophosphamide. The associated variables in the multivariate were the Charlson Index (p=0.004) and the SLICC (p<0.001). Conclusions: CVDs have a significant influence on our patients, being associated with a greater possibility of damage and comorbidities.

Desfechos clínicos e gravidade da infecção pelo Clostridioides (Clostridium) difficile em um hospital terciário de referência no Brasil / Clinical outcome and severity of clostridioides (clostridium) difficile infection at a tertiary referral hospital in brazil

ABSTRACT Background: Clostridioides difficile infection (CDI) is a potentially severe disease that can present with refractoriness, recurrence, and evolution to death. In Brazil, the epidemiology of CDI seems to differ from that of the United States and most European countries, with only one ribotype (RT) 027-related case and a high prevalence of RT106. Objective: The aim of this study was to evaluate the outcomes of CDI and its possible association with ribotypes at a university hospital in Brazil. Methods: A total of 65 patients with CDI were included and stool samples were submitted to A/B toxin detection and toxigenic culture, and toxigenic isolates (n=44) were also PCR ribotyped. Results: Patients' median age was 59 (20-87) years and there were 16 (24.6%) deaths. The median Charlson comorbidity index (CCI) was 4 (0-15) and 16.9% of the patients had CCI ≥8. The ATLAS score and non-improvement of diarrhea were related to higher mortality. A longer length of hospitalization was related to the enteral nutrition and use of multiple antibiotics. The period between CDI diagnosis and hospital discharge was longer in those who received new antibiotics after diagnosis, multiple antibiotics, and required intensive care treatment. Recurrence was associated with CCI >7. Twenty ribotypes were identified and RT106 was the most frequently detected strain (43.2%). No relationship was observed between the ribotypes and outcomes. CDI was present in patients with more comorbidities. Conclusion: Risk factors for higher mortality, longer hospital stay and recurrence were identified. A diversity of ribotypes was observed and C. difficile strains were not related to the outcomes.

RESUMO Contexto: A infecção pelo Clostridioides difficile (ICD) é uma doença potencialmente grave que pode se apresentar com refratariedade, recidiva e evoluir para óbito. No Brasil, a epidemiologia da ICD parece diferir da dos Estados Unidos e da maioria dos países europeus, com apenas um caso relacionado ao ribotipo (RT) 027 e alta prevalência do RT106. Objetivo: Avaliar os desfechos da ICD e sua possível associação com ribotipos em um hospital universitário do Brasil. Métodos: Um total de 65 pacientes com ICD foram incluídos e amostras de fezes foram submetidas à detecção de toxina A/B e cultura toxigênica e as cepas toxigênicas isoladas (n=44) também foram ribotipadas por PCR. Resultados: A idade mediana dos pacientes foi de 59 (20-87) anos e houve 16 (24,6%) óbitos. A mediana do índice de comorbidade de Charlson (ICC) foi de 4 (0-15) e 16,9% dos pacientes apresentaram ICC ≥8. O escore ATLAS e a não melhora da diarreia foram relacionados a maior mortalidade. Maior tempo de internação esteve relacionado à nutrição enteral e ao uso de múltiplos antibióticos. O período entre o diagnóstico de ICD e a alta hospitalar foi maior naqueles que receberam novos antibióticos após o diagnóstico, múltiplos antibióticos e necessitaram de tratamento intensivo. A recorrência foi associada com ICC >7. Vinte ribotipos foram identificados e o RT106 foi a cepa mais frequentemente detectada (43,2%). Não foi observada relação entre os ribotipos e os desfechos. ICD esteve presente em pacientes com mais comorbidades. Conclusão: Foram identificados fatores de risco para maior mortalidade, maior tempo de internação e recorrência. Uma diversidade de ribotipos foi observada e cepas de C. difficile não foram relacionadas aos desfechos.

Multidisciplinary Cognitive Function Assessment of Good versus Poor Performance in Children with Cochlear Implants: An Observational Cross-Sectional Study

Abstract Introduction Despite the developing technology of cochlear implants (CIs), implanted prelingual hearing-impaired children exhibit variable speech processing outcomes. When these children match in personal and implant-related criteria, the CI outcome variability could be related to higher-order cognitive impairment. Objectives To evaluate different domains of cognitive function in good versus poor CI performers using a multidisciplinary approach and to find the relationship between these functions and different levels of speech processing. Methods This observational, cross-sectional study used the word recognition score (WRS) test to categorize 40 children with CIs into 20 good (WRS/65%) and 20 poor performers (WRS < 65%). All participants were examined for speech processing at different levels (auditory processing and spoken language) and cognitive functioning using (1) verbal tests (verbal component of Stanford-Binet intelligence [SBIS], auditory memory, auditory vigilance, and P300); and (2) performance tasks (performance components of SBIS, and trail making test). Results The outcomes of speech processing at different functional levels and both domains of cognitive function were analyzed and correlated. Speech processing was impaired significantly in poor CI performers. This group also showed a significant cognitive function deficit, in which the verbal abilities were more affected (in 93.5%) than in the good performers (in 69.5%). Moreover, cognitive function revealed a significant correlation and predictive effect on the CI speech outcomes. Conclusion Cognitive function impairment represented an important factor that underlies the variable speech proficiency in cochlear-implanted children. A multidisciplinary evaluation of cognitive function would provide a comprehensive overview to improve training strategies.
