Case Report: Cutaneous Leishmaniasis: A Case Series with Intralesional Treatment in Northeast Brazil.

In 2022, the Pan American Health Organization recommended the intralesional application (IL) of pentavalent antimonials in adult patients with localized cutaneous leishmaniasis (CL) caused by Leishmania (Viannia) braziliensis. Other guidelines differ from that recommendation, considering that infections caused by a Leishmania species that can be associated with increased risk for mucosal leishmaniasis, in particular L. (V.) braziliensis, should not be eligible for intralesional treatment. This was a prospective interventional study carried out with eight patients diagnosed with CL residing in northeast Brazil during the period from 2019 to 2022. To our knowledge, this is the first prospective study on the subject conducted in the northeast region, which has the second-highest number of cases in the country. In our sample, clinical cure was achieved with the use of intralesional treatment in all cases, and there were no serious adverse events or mucosal involvement during the 1-year follow-up period. We emphasize the importance of using the right criteria for choosing this therapeutic modality and highlight the advantages of intralesional treatment due to the lower risk of adverse events and cost reduction to health services.

Oxygenated versus non-oxygenated flush out during deceased donor liver procurement: The first proof-of-concept study in humans.

BACKGROUND: Liver transplantation is used for treating end-stage liver disease, fulminant hepatitis, and oncological malignancies and organ shortage is a major limiting factor worldwide. The use of grafts based on extended donor criteria have become internationally accepted. Oxygenated machine perfusion technologies are the most recent advances in organ transplantation; however, it is only applied after a period of cold ischemia. Due to its high cost, we aimed to use a novel device, OxyFlush®, based on oxygenation of the preservation solution, applied during liver procurement targeting the maintenance of ATP during static cold storage (SCS). METHODS: Twenty patients were randomly assigned to the OxyFlush or control group based on a 1:1 ratio. In the OxyFlush group, the perfusion solution was oxygenated with OxyFlush® device while the control group received a non-oxygenated solution. Liver and the common bile duct (CBD) biopsies were obtained at three different time points. The first was at the beginning of the procedure, the second during organ preparation, and the third after total liver reperfusion. Biopsies were analyzed, and adenosine triphosphate (ATP) levels and histological scores of the liver parenchyma and CBD were assessed. Postoperative laboratory tests were performed. RESULTS: OxyFlush® was able to maintain ATP levels during SCS and improved the damage caused by the lack of oxygen in the CBD. However, OxyFlush® did not affect laboratory test results and histological findings of the parenchyma. CONCLUSION: We present a novel low-cost device that is feasible and could represent a valuable tool in organ preservation during SCS.

The Role of Extracellular Vesicles in Metabolic Diseases.

Extracellular vesicles represent a group of structures with the capacity to communicate with different cells and organs. This complex network of interactions can regulate multiple physiological processes in the organism. Very importantly, these processes can be altered during the appearance of different diseases including cancer, metabolic diseases, etc. In addition, these extracellular vesicles can transport different cargoes, altering the initiation of the disease, driving the progression, or even accelerating the pathogenesis. Then, we have explored the implication of these structures in different alterations such as pancreatic cancer, and in different metabolic alterations such as diabetes and its complications and non-alcoholic fatty liver disease. Finally, we have explored in more detail the communication between the liver and the pancreas. In summary, extracellular vesicles represent a very efficient system for the communication among different tissues and permit an efficient system as biomarkers of the disease, as well as being involved in the extracellular-vesicle-mediated transport of molecules, serving as a potential therapy for different diseases.

Ultra-diluted complex additive in the diet reveals benefits in the intestinal tract of nursery-phase piglets.

This study aimed to assess an ultra-diluted (UD) complex, as a replacement for an antimicrobial growth promoter in diets, on growth performance, intestinal health, and inflammatory response of nursery piglets. The experiment lasted 37 days and involved 126 animals weaned at 21 ± 1.3 d, with an initial body weight of 5.62 ± 1.16 kg. Piglets were assigned to six dietary treatments in a randomized block design with seven replicates and three piglets per pen as experimental unit. The treatments were: positive control (PC)- basal diet + 120 mg/kg of chlorohydroxyquinoline; negative control (NC)- basal diet without additives; and NC containing 4.5; 6.0; 7.5 or 9.0 kg of UD additive/ton diet. Performance data were calculated, and daily diarrhea was observed. Blood samples were collected for hematological analysis. At the end of the experiment, one animal per pen was slaughtered for organ weighing, pH, and the collection of intestinal samples for histopathology. Feces and cecal contents were collected for microbiological and antibiogram analyses. There was no difference in the performance between the treatments. Throughout the study, UD levels were equal to those of PC for diarrhea occurrence. Higher levels of UD complex led to higher total leukocyte counts. The 4.5 treatment showed a reduction in total and thermotolerant Enterobacteriaceae populations in piglet feces and an increase in lactic acid bacteria compared to PC. All treatments resulted in fewer duodenal histopathological alterations than those in the NC group. The use of UD additives, especially at 4.5 kg/ton, is a good alternative to chlorohydroxyquinoline in piglet diets.

Effect of transcranial direct current stimulation combined with pelvic muscle training in women: Randomized, controlled, double-blind, and clinical trial.

BACKGROUND: Pelvic floor muscle training (PFMT) is widely used for pelvic floor muscle (PFM) weakness in women; however, it has no prolonged effects. OBJECTIVE: To evaluate the effect of Transcranial Direct Current Stimulation (tDCS) associated with PFMT on PFM contraction, sexual function and quality of life (QoL) in healthy women. STUDY DESIGN: 32 nulliparous women, aged 22.7 ± 0.42 years, were randomized into two groups: G1 (active tDCS combined with PFMT) and G2 (sham tDCS combined with PFMT). The treatment was performed three times a week for 4 weeks, totaling 12 sessions. PFM function was assessed using the PERFECT scheme (P = power, E = endurance, R = repetitions, F = rapid contractions, ECT = each timed contraction) and the perineometer (cmH2O). Sexual function was assessed by The Female Sexual Function Index, and QoL by the SF-36 questionnaire. These assessments were performed before and after the 12nd treatment session and after 30-day follow-up. RESULTS: There was a significant increase (p = 0.037) in the power of G2 compared to G1; repetitions and fast contraction increased in the G1 group, and the resistance increased in both groups, however, without statistical difference between the groups. ECT increased in the G1 group (p = 0.0). CONCLUSION: Active tDCS combined with PFMT did not potentiate the effect of the PFMT to increase the PFM function, QoL, and sexual function in healthy women. However, adjunctive tDCS to PFMT improved the time of contractions, maintaining it during follow-up.

O processo de trabalho dos profissionais de saúde de uma unidade de saúde da família no cenário de pandemia pela covid-19 / Family health unit work process during the covid-19 pandemic / El proceso de trabajo de los profesionales de la salud en una unidad de salud familiar en el escenario de la pandemia de la covid-19

Em janeiro de 2020, a Organização Mundial da Saúde declarou a covid-19 como uma emergência em Saúde Pública, sendo posteriormente, em março do mesmo ano, reconhecida como pandemia. O Brasil registrou o primeiro caso em fevereiro de 2020. Esse novo cenário epidemiológico exigiria da Atenção Primária à Saúde a reorganização do processo de trabalho e dos fluxos assistenciais para o enfrentamento do problema e garantia do acesso da população aos serviços. Assim, este trabalho relata a estratégia de reorganização do processo de trabalho dos profissionais de saúde de uma Unidade de Saúde da Família em município baiano diante do cenário de pandemia pela covid-19 entre março de 2020 a março de 2021. É um estudo observacional descritivo do tipo relato de experiência. O processo de trabalho foi reorganizado incorporando tecnologias de cuidado, como a teleconsulta, telemonitoramento, implantação do acolhimento com classificação de risco, readequação do ambiente físico e intensificação da utilização de Equipamentos de Proteção Individual. A Atenção Primária à Saúde exerce papel estratégico nas ações de combate à covid-19 no território, e as estratégias utilizadas pela Unidade de Saúde da Família possibilitaram o acesso da população ao serviço, mesmo diante da restrição de algumas atividades de rotina. Contudo, foram observados prejuízos no cuidado longitudinal dos usuários e no processo formativo de alunos da graduação e da pós-graduação, devido à interrupção dos estágios na Atenção Primária à Saúde como medida de segurança.

On January 2020, the World Health Organization (WHO) declared the COVID-19 as a public health emergency, and in March of the same year, the new disease was recognized as a pandemic. Brazil registered its first case in February 2020. This new epidemiological scenario required Primary Health Care (PHC) to reorganize its care process and workflows to address the issue and ensure the population's access to services. Thus, this descriptive observational report presents the work process of health professionals at a Family Health Unit in a municipality from Bahia, Brazil, during the pandemic. Reorganization of the work process included incorporating care technologies such as teleconsultation, telemonitoring, user embracement with risk classification, readjustment of the physical environment and intensification of Personal Protective Equipment (PPE) use. Primary Health Care plays a strategic role in actions to combat the COVID-19 in the territory and the FHU strategies adopted allowed the population to access services even in the face of restriction. However, user longitudinal care and the training process of undergraduate and graduate students suffered losses due to the interruption of internships in Primary Health Care as a safety measure.

En enero de 2020, la Organización Mundial de la Salud declaró como emergencia de salud pública a la covid-19 y, posteriormente, en marzo del mismo año, la reconoció como pandemia. Brasil registró el primer caso en febrero de 2020. Este nuevo escenario epidemiológico requirió de la atención primaria de salud (APS) una reorganización del proceso de trabajo y de los flujos de atención para enfrentar el problema y asegurar el acceso de la población a los servicios. Este trabajo busca informar la estrategia respecto a la reorganización del proceso de trabajo de los profesionales de la salud en una Unidad de Salud Familiar en un municipio de Bahía (Brasil) frente a la pandemia de la covid-19 en el período comprendido entre marzo de 2020 y marzo de 2021. Este es un estudio observacional descriptivo, de tipo reporte de experiencia. Se reorganizó el proceso de trabajo incorporando tecnologías de cuidado, como teleconsulta, telemonitoreo, implementación de clasificación de riesgo, readecuación del ambiente físico y mayor uso de equipos de protección personal (EPP). La atención primaria de salud juega un papel estratégico en las acciones de enfrentamiento al covid-19 en el territorio y las estrategias utilizadas por las Unidades de Salud Familiar permitieron a la población acceder al servicio, incluso frente a la restricción en algunas actividades rutinarias. Sin embargo, se observaron perjuicios en la atención longitudinal de los usuarios y en el proceso de formación de los estudiantes de grado y posgrado debido a la interrupción de las pasantías en la atención primaria como medida de seguridad.

Seasonal variations in botanical and nutritive composition, forage availability and ingestive behavior of grazing goats in the semiarid region.

The aim of this study was to assess how the different seasons of the year impact the botanical composition, availability, and quality of forage in the caatinga, as well as the frequency of ingestion and ingestive behavior of goats in a semi-arid region. The experiment used four crossbred castrated males, with an average weight of 30.2 ± 4.76 kg and an average age of 20 months. The experimental period lasted for 12 months, encompassing two rainy seasons and one dry season within this timeframe, with three replications (data collection) per season. All collected forage was categorized based on its stratum (herbaceous, woody, and litter), and a chemical composition analysis was conducted. The goats' behavior was assessed by observing variables such as feeding time, idleness, rumination, displacement, social interaction, and water intake. The findings revealed clear seasonality in both availability and quality of forage, consequently influencing the botanical composition of the goats' diet and their ingestive behavior. In addition, during the grazing period, the goats showed a shift grazing habit, in which idle and feeding peaks were alternated with increased displacement during the morning and rumination in the afternoon. The seasons of the year strongly impact the availability and nutritional quality of forage in the caatinga biome, consequently influencing the ingestive behavior and dietary composition of goats in this ecosystem.

The microarchitecture and chemical composition of the femur neck of senescent female rats after different physical training protocols.

A sedentary lifestyle, coupled with a decrease in estrogen, impairs bone homeostasis, favoring to the development of osteopenia and osteoporosis, both recognized as risk factors for fractures. Here, we investigated the quality of the femur, particularly the femur neck region, and the ambulation performance of senescent rats subjected to three different physical training protocols during the periestropause period. Forty-eight female rats, 18 months of age, were subjected to a 120-day training period, three times a week. The rats were distributed into four groups: aerobic training (AT), strength training (ST), concurrent training (CT), or no training (NT). After the experimental period, at 21 months of age, ambulation performance and femur were analyzed using microtomography, Raman stereology, densitometry, and mechanical strength tests. The results demonstrated greater remodeling activity and improvement in resistance and bone microarchitecture in the femur neck of senescent female rats after undergoing physical training. Our verified higher intensities of bands related to collagen, phosphate, amide III, and amide I. Furthermore, the analysis of the secondary collagen structures indicated alterations in the collagen network due to the exercise, resulting in increased bone strength. Both AT and strength-based training proved beneficial, with AT showing greater adaptations in bone density and stiffness in the femur, while strength-based training greater adaptations in trabecular and cortical structure. These insights contribute to the understanding of the potential interventions for preventing osteopenia and osteoporosis, which are critical risk factors for fractures.

A Fresh Cadaver Study on the Innervation of Brachioradialis and Extensor Carpi Radialis Longus Muscles.

PURPOSE: Distal nerve transfers have revolutionized peripheral nerve surgery by allowing the transfer of healthy motor nerves to paralyzed ones without causing additional morbidity. Radial nerve branches to the brachialis (Ba), brachioradialis (Br), and extensor carpi radialis longus (ECRL) muscles have not been investigated in fresh cadavers. METHODS: The radial nerve and its branches were dissected in 34 upper limbs from 17 fresh cadavers. Measurements were taken to determine the number, origin, length, and diameter of the branches. Myelinated fiber counts were obtained through histological analysis. RESULTS: The first branch of the radial nerve at the elbow was to the Ba muscle, followed by the branches to the Br and ECRL muscles. The Ba and Br muscles consistently received single innervation. The ECRL muscle showed varying innervation patterns, with one, two, or three branches. The branches to the Br muscles originated from the anterior side of the radial nerve, whereas the branches to the Ba and ECRL muscles originated from the posterior side. The average myelinated fiber counts favored the nerve to Br muscle over that to the ECRL muscle, with counts of 542 versus 350 and 568 versus 302 observed in hematoxylin and eosin and neurofilament staining, respectively. CONCLUSIONS: This study provides detailed anatomical insights into the motor branches of the radial nerve to the Ba, Br, and ECRL muscles. CLINICAL RELEVANCE: Understanding the anatomy of the radial nerve branches at the elbow is of utmost importance when devising a reconstructive strategy for upper limb paralysis. These findings can guide surgeons in selecting appropriate donor or recipient nerves for nerve transfer in cases of high tetraplegia and lower-type brachial plexus injuries.

Effects of Transcranial Direct Current Stimulation and Pelvic Floor Muscle Training in Women: protocol for a controlled, randomized, double-blind clinical trial / Efectos de la estimulación transcraneal por corriente directa y del entrenamiento muscular del suelo pélvico en mujeres: protocolo de un ensayo clínico controlado, aleatorizado y doble ciego / Efeitos da estimulação transcraniana por corrente contínua e treinamento muscular do assoalho pélvico em mulheres: protocolo para um ensaio clínico controlado, randomizado e duplo-cego

ABSTRACT Pelvic floor muscle weakness can lead to urinary incontinence, pelvic organ prolapse, and sexual dysfunction. Although it can be minimized by pelvic floor muscle training (PFMT), its effects are not lasting. Therefore, using combination therapy seems promising. This study aims to evaluate the effect of transcranial direct current stimulation (tDCS) combined with PFMT on intravaginal pressure, pelvic floor muscle strength (PFMS), sexual function (SF), and quality of life (QoL) in healthy women. A total of 32 women, aged from 18 to 45 years, will undergo PFMT (with perineal contractions and relaxation) with the aid of pressure biofeedback associated with active tDCS or sham tDCS. Sessions will last 20 minutes, three times per week, for four weeks, totaling 12 sessions. During the protocol, participants will be instructed to also perform the home-based PFMT daily. The tDCS anodal electrode will be positioned over the supplementary motor area of the dominant cortical hemisphere, whereas the cathodal will be over the contralateral supraorbital region, with a 2mA intensity for 20 minutes. Intravaginal pressure (pressure gauge), PFM strength (measured by digital palpation and the PERFECT scheme), FSFI (Female Sexual Function Index), and QoL (SF-36 questionnaire) will be evaluated before and after the 12 sessions and after a 30-day follow-up.

RESUMEN La debilidad de la musculatura del suelo pélvico puede provocar incontinencia urinaria, prolapso de órganos pélvicos y disfunción sexual, y puede minimizarse mediante el entrenamiento de la musculatura del suelo pélvico (EMSP). Sin embargo, este efecto no es duradero. En este contexto, una terapia combinada puede ser prometedora para mejorar la situación. Este estudio tiene por objetivo evaluar el efecto de la estimulación transcraneal por corriente directa (ETCC) combinada con EMSP sobre la presión intravaginal, la fuerza muscular del suelo pélvico (FMSP), la función sexual (FS) y la calidad de vida (CV) en mujeres sanas. Participarán 32 mujeres, de entre 18 y 45 años, que se someterán a EMSP (contracciones y relajación del perineo) y a Biofeedback asociado a ETCC activa o ETCC sham durante 20 minutos, tres veces por semana, durante 4 semanas, con un total de 12 sesiones. Durante el protocolo, las participantes también se someterán diariamente a EMSP en casa. El electrodo anodal de la ETCC se colocará sobre el área motora suplementaria del hemisferio cortical dominante, y el electrodo catodal sobre la región supraorbital contralateral, a una intensidad de 2 mA, durante 20 minutos. Se evaluarán la presión intravaginal (manómetro), la FMSP (palpación digital, esquema Perfect), la FS (Índice de Función Sexual Femenina) y la CV (cuestionario SF-36) antes y después de las 12 sesiones, así como tras un seguimiento de 30 días.

RESUMO A fraqueza muscular do assoalho pélvico pode gerar incontinência urinária, prolapso de órgãos pélvicos e disfunção sexual, e pode ser minimizada pelo treinamento muscular do assoalho pélvico (TMAP). No entanto, este efeito não é duradouro. Assim, terapia combinada parece ser promissora para a melhora deste quadro. Dessa forma, objetiva-se avaliar o efeito da estimulação transcraniana por corrente contínua (ETCC), combinada ao TMAP, sobre a pressão intravaginal, força muscular do assoalho pélvico (FMAP), função sexual (FS) e qualidade de vida (QV) em mulheres saudáveis. Serão 32 mulheres, entre 18 e 45 anos, que realizaram TMAP (contrações e relaxamento do períneo) e Biofeedback associados a ETCC ativa ou ETCC sham por 20 minutos, três vezes por semana, por 4 semanas, totalizando 12 sessões. Durante o protocolo, as participantes também realizarão diariamente, em domicílio, o TMAP. O eletrodo anodal da ETCC será posicionado sobre a área motora suplementar do hemisfério cortical dominante, e o catodal sobre a região supraorbital contralateral, com intensidade de 2mA, por 20 minutos. A pressão intravaginal (manômetro de pressão), FMAP (palpação digital, esquema Perfect), FS (Índice de Função Sexual Feminina) e QV (questionário SF-36) foram avaliadas antes e depois das 12 sessões, bem como após acompanhamento de 30 dias.

Stress level and quality of life following pediatric cataract surgery / Avaliação do nível de estresse e de qualidade de vida em crianças submetidas à cirurgia de catarata

ABSTRACT Purpose: To evaluate the quality of life and stress level related to visual function following pediatric cataract surgery in a Brazilian public hospital. Methods: This prospective study analyzed children aged 6-14 years old who underwent cataract surgery. The Childhood Stress Scale and Children's Visual Function Questionnaire (CVFQ) were used to assess stress levels and quality of life, respectively. Both instruments were applied by two psychologists before and after the surgery. Eye examination was performed by two ophthalmologists. Preoperative and postoperative data were compared. Results: In total, 23 children (32 eyes) were enrolled in the study, of which 9 had bilateral cataracts. The average age group at the time of surgery was 9.65 ± 2.26 (6-14) years old. One month after the surgery, the spherical equivalent was -0.90 ± 1.66D, and the corrected distance visual acuity was 0.13 ± 0.10 (0-0.3) LogMAR in bilateral cases and 0.50 ± 0.39 (0-1.3) LogMAR in unilateral cases (p<0.01). According to the Childhood Stress Scale, 77.7% of the bilateral cases and 57.1% of the unilateral cases had stable stress levels, and 34.7% of the children improved their stress level. The analysis of the CVFQ was based on scores for general health, general vision health, competence, personality, and treatment. After cataract surgery, 78.2% of the patients had improved or maintained CVFQ scores in the general health domain; 82.6%, general vision health; 95.6%, competence; 56.5%, personality; and 78.2%, treatment. Conclusion: Pediatric cataract surgery improves the visual function and the quality of life even in patients undergoing surgical procedures, without increasing the stress levels.

Métodos: Estudo prospectivo em crianças de seis a 14 anos submetidas à cirurgia de catarata. A Escala de Stresse Infantil e o Questionário de Função Visual em Crianças foram usados para avaliar o nível de estresse e a qualidade de vida, respectivamente. Ambos os instrumentos foram aplicados por duas psicólogas antes e após a cirurgia. O exame oftalmológico foi realizado por dois oftalmologistas. Os dados coletados no pré e pós-operatório foram comparados. Resultados: Vinte e três crianças (32 olhos) foram incluídas no estudo, nove delas apresentavam catarata bilateral. A média de idade na cirurgia foi de 9,65±2,26 (6 a 14) anos. Um mês após a cirurgia, o equivalente esférico foi de -0,90 ± 1,66D e a acuidade visual corrigida a distância foi de 0,13 ± 0,10 (0-0,3) LogMAR em casos bilaterais e 0,50 ± 0,39 (0-1,3) LogMAR em casos unilaterais (p<0.01). De acordo com a Escala de Stresse Infantil, 77,7% dos casos de catarata bilaterais, e 57,1% dos casos unilaterais mantiveram o nível de estresse e 34,7% das crianças melhoraram o nível de estresse. A análise do Questionário de Função Visual em Crianças foi baseada em pontuações para saúde geral, saúde geral da visão, competência, personalidade e tratamento. Após a cirurgia de catarata, 78,2% dos pacientes melhoraram ou mantiveram o escore do Questionário de Função Visual em Crianças na saúde geral, 82,6% na saúde geral da visão, 95,6% na competência, 56,5% na personalidade e 78,2% no tratamento. Conclusão: A cirurgia de catarata pediátrica melhora a função visual e a qualidade de vida em pacientes submetidos a procedimento cirúrgico, sem aumentar o nível de estresse.

Knowledge of Physical Education Students about Tooth Avulsion Before and After Receiving an Informative Leaflet

Abstract Objective: To evaluate the knowledge of Physical Education students about tooth avulsion (TA) in both dentitions before and after receiving an informative leaflet (IL). Material and Methods: The questionnaire contained information about TA in dentition and its management and was applied to the Physical Education students before and after reading an IL. Results: A total of 118 students, 96.61%, attended a first aid course, and 17.80% received information about TA. Most students (88.98%) never had an experience with TA, and 90.68% considered its management important. The other questions, before and after reading the IL, respectively, were: would not perform deciduous tooth replantation (42%; 88%); knew how to handle the avulsed permanent tooth (APT) (38%; 92%); knew how to clean the APT (50%; 99%); knew that permanent tooth replantation (PTR) must be immediate (15%; 95%); knew the ideal time to seek for the dentist right after TA without performing PTR (6%; 83%); knew how to store APT (31%; 97%). Conclusion: The knowledge of Physical Education students in this research revealed a limited understanding of dental tooth avulsion. After receiving an informative leaflet, the students showed a significant improvement in knowledge about traumatic avulsion management, including tooth replantation and proper actions.

Discurso do Analista e Democracia em Risco: Por Que o Psicanalista Não Pode Ser Bolsonarista? / The Analyst Discourse and Democracy at Risk: Why Can't the Psychoanalyst Be Bolsonarista? / El Discurso del Analista y la Democracia en Riesgo: ¿Por Qué el Psicoanalista No Puede Ser Bolsonarista?

O objetivo deste trabalho é responder por que um psicanalista não pode ser bolsonarista. Para isso, partimos da articulação entre a noção de pós-verdade e verdade sob uma perspectiva psicanalítica. Por meio de uma revisão teórica, discorremos sobre tais perspectivas tendo como cenário o contexto brasileiro das últimas eleições presidenciais e da gestão da pandemia de COVID-19. Articulamos pós-verdade e verdade a uma terceira noção, a autoverdade, a partir da discussão sobre a importância que assume o discurso do psicanalista quando este se posiciona diante dos outros discursos propostos por Lacan, sobretudo em um contexto de risco à democracia. Concluímos que a partir da dimensão clínica, eixo central de sua prática, o psicanalista não pode ser bolsonarista porque, ao ocupar o lugar de a, não estabelece com o outro uma relação de manutenção de um gozo destrutivo, gozo que não leva em conta a responsabilidade subjetiva cujas incidências mais prementes se dão sobre a vivência da alteridade.

The objective of this work is to answer why a psychoanalyst cannot be a bolsonarista. For this, we start from the articulation between the notion of post-truth and the truth in a psychoanalytical perspective. Through a predominantly psychoanalytical theoretical review, we discuss such perspectives against the brazilian's last presidential elections and the management of the COVID-19 pandemic background. We intend to articulate the discussion about the importance that the psychoanalyst's discourse assumes when it takes a position in relation to other discourses, proposed by Lacan, especially in a democracy risk's context. We conclude that from the clinical practice, the central axis of his job, the psychoanalyst cannot be a bolsonarista because, by occupying the place of a, he does not establish with the other a relationship of maintenance of a destructive jouissance, jouissance that does not take into account the subjective responsibility whose most pressing incidences are on the experience of alterity.

Public health policies for children and youth with special health care needs in OECD member countries and Brazil: A scoping review protocol.

BACKGROUND: Because public health policies lay down guidelines for health promotion in specific populations, a review of policies devised for children and youth with special health care needs (CYSHCN) can reveal the actual degree of priority assigned to this population segment, while also highlighting relevant policies in this field. OBJECTIVE: To map the available evidence of public health policies for CYSHCN in member countries of the Organization for Economic Cooperation and Development (OECD) and Brazil. METHOD: A scoping review protocol was developed as per the Joanna Briggs Institute (JBI) manual and the Preferred Reporting Items for Systematic Review and Meta-Analyses-Extension for Scoping Reviews (PRISMA-ScR) checklist, for application to the Web of Science (WoS), Scopus, PubMed, and Embase databases;to theLatin American and Caribbean Literature in Health Sciences (LILACS)multilingual thesaurus; and to gray literature.The review will map the principal documents (irrespective of time frame or language) addressing public health policies for CYSHCN up to 19 years old. The research protocol has been registered on the Open Science Framework platform (identifier 10.17605/OSF.IO/UW5BH:DOI). RESULTS AND CONCLUSION: Tables, maps, charts, and/or graphs accompanied by descriptive texts will be employed to present the results to the research question and provide answers to it. Use of both open-access software IRaMuTeQ for similitude analysis and word clouds is also planned. This protocol is expected to reveal policies that meet the specific needs of this vulnerable population segment and highlight examples of good practices or current gaps.

A new cyclodipeptide from Tetragonisca angustula honey active against Neospora caninum and in silico study.

A new cyclic natural compound formed by succinic acid and two alanine amino acid units was isolated from the Tetragonisca angustula honey extract. The chemical structure of 1 was established based on spectroscopic data analysis, including one- (1H and 13C NMR) and two-dimensional NMR techniques (1H-1H-COSY, HSQC and HMBC). A primary culture model previously infected with Neospora caninum was used to evaluate 1 for two time intervals (24 and 72 h), showing a reduction (40-56%) of the number of tachyzoites in the first 24 h and until 72 h, a dose-dependent reduction in parasite proliferation (25-50%). Glial cells treated with 1 did not demonstrate toxicity at concentrations up to 25 ug/mL. Treated and infected cultures showed an increase in NO when compared to control cells in 24 h and 72 h. In silico studies suggest that the new compound may affect DNA synthesis and impair -protein production.

Pregnancy incidence, outcomes and associated factors in a cohort of women living with HIV/AIDS in Rio de Janeiro, Brazil, 1996-2016.

The aim of this research was to analyze pregnancy incidence and associated factors in a cohort of 753 women living with HIV/AIDS (WLWHA) in Rio de Janeiro, Brazil, from 1996 to 2016. Women aged 18-49 years who were not on menopause (surgical or natural) and did not have a tubal ligation were eligible for the study. Data were collected by medical professionals during initial and follow-up visits. Person-time pregnancy incidence rates were calculated throughout the follow-up period. Pregnancy incidence-associated factors were investigated by univariate and multiple analyzes, using an extension of the Cox survival model. Follow-up visits recorded 194 pregnancies, with an incidence rate of 4.01/100 person-years (95% CI: 3.47; 4.60). A higher pregnancy incidence was associated with CD4 nadir ≥ 350 cells/mm³, use of an antiretroviral regimen not containing Efavirenz, and prior teenage pregnancy. In turn, women with a viral load ≥ 50 copies/mL, age ≥ 35 years old, with two or more children and using a highly effective contraceptive method showed a lower incidence. Results showed a significant reduction in pregnancy incidence after 2006, a significant reduction in female sterilization from 1996 to 2016, and a high rate of cesarean sections. The association found between pregnancy incidence and the use of contraceptive methods and virological control markers suggests a good integration between HIV/AIDS and reproductive health services. The high rate of cesarean section delivery indicates the need to improve childbirth care.

URGENT LIVER RETRANSPLANTATION DUE TO TRANSMISSION OF INTRAHEPATIC CHOLANGIOCARCINOMA BY DONOR: THE FIRST REPORT IN THE LITERATURE.

BACKGROUND: Liver transplantation represents the best therapeutic modality in end-stage chronic liver disease, severe acute hepatitis, and selected cases of liver tumors. AIMS: To describe a double retransplant in a male patient diagnosed with Crohn's disease and complicated with primary sclerosing cholangitis, severe portal hypertension, and cholangiocarcinoma diagnosed in the transplanted liver. METHODS: A 48-year-old male patient diagnosed with Crohn's disease 25 years ago, complicated with primary sclerosing cholangitis and severe portal hypertension. He underwent a liver transplantation in 2018 due to secondary biliary cirrhosis. In 2021, a primary sclerosing cholangitis recurrence was diagnosed and a liver retransplantation was indicated. Recipient's hepatectomy was very difficult by reason of complex portal vein thrombosis requiring extensive thromboendovenectomy. Intraoperative ultrasound with liver doppler evaluation was performed. Two suspicious nodules were incidentally diagnosed in the donor's liver and immediately removed for anatomopathological evaluation. RESULTS: After pathological confirmation of carcinoma, probable cholangiocarcinoma, at frozen section, the patient was re-listed as national priority and a new liver transplantation was performed within 24 hours. The patient was discharged after 2 weeks. CONCLUSIONS: The screening for neoplasms in donated organs should be part of our strict daily diagnostic arsenal. Moreover, we argue that, for the benefit of an adequate diagnosis and the feasibility of a safer procedure, the adoption of imaging tests routine for the liver donor is essential, allowing a reduction of the costs and some potential risks of liver transplant procedure.

Evaluation of the tissue repair process and immunomodulatory action of Platelet-Rich Plasma (PRP) in the treatment of abdominal stretch marks.

The aims of this study were to characterize and to compare the structural alterations of collagen and elastic fibers in the abdominal stretch marks of patients submitted to intralesional and per quadrant (region close to stretch marks) Platelet-Rich Plasma (PRP) treatment, as well as, to establish the possible mechanisms of action of this treatment involving toll-like receptors (TLRs) signaling pathways and growth factors. Incisional biopsies were collected from abdominal stretch marks with a 2 mm diameter punch in female patients, at the beginning of treatment, after 6 and 12 weeks of treatment, and submitted to morphological analyzes of elastic and collagen fibers, and immunohistochemistry for TLRs signaling pathways and growth factors. Our results demonstrated PRP per quadrant treatment was most effective in reducing the area of the abdominal stretch marks, with consequent stimulation of the synthesis and remodeling of collagen and elastic fibers. Also, PRP per quadrant treatment promoted an increase in TLR2 and TLR4 immunoreactivities, with consequent increase in TNF-α, VEGF and IGF-1. Based on the current findings, PRP constitutes a promising therapeutic approach in patients with stretch marks, since it promoted modulation of inflammatory cytokines and growth factors, with consequent remodeling of extracellular matrix, culminating with tissue improvement.

Using umbilical cord blood as a source of paediatric packed red blood cells: Processing and quality control.

BACKGROUND AND OBJECTIVES: Umbilical cord blood (UCB) has been used as a source of red blood cells (RBCs) for neonatal/paediatric transfusion purposes. This study adopted two different procedures to obtain umbilical RBC (U-RBC) to compare its quality control parameters to those of fractionated adult RBC (A-RBC), for paediatric purposes. MATERIALS AND METHODS: UCB units (24) were filtered and processed based on two different methods, namely, conventional/manual (P1;n12) and automatic (P2;n12). They were compared to five fractionated A-RBCs. U-RBC and A-RBC were stored for 14 days and had their haematological, biochemical, haemolytic and microbiological parameters analysed at D1, D7 and D14. Cytokines and growth factors (GFs) in residual U-RBC plasma were measured. RESULTS: Mean volume of processed U-RBC units was 45 mL for P1 and 39 mL for P2; the mean haematocrit level reached 57% for P1 and 59% for P2. A-RBC recorded a mean volume of 44 mL. Haematologic and biochemical parameters analysed in U-RBC and A-RBC presented similar behaviours during storage time, except for parameter values, which differed between them. Pro-inflammatory and immunomodulatory cytokines, as well as GFs, were higher in U-RBC residual plasma than in that A-RBC. CONCLUSION: UCB can be processed into RBC based on either manual or automated protocols. U-RBC units met the referenced quality parameters defined for A-RBC. Some features, mainly the biochemical ones, should be further investigated to help improve quality parameters, with emphasis on differences found in, and particularities of, this material and on recipients of this new transfusion practice.
