RESUMO

O presente artigo explora alguns impactos políticos e sociais reconhecidos nos dez anos que sucederam as manifestações de junho de 2013, dando ênfase a um fator específico: o papel das mídias sociais no cenário político e na mobilização de grupos. Partindo desse foco, trata da possibilidade de que tais ferramentas digitais possam ser melhor exploradas por certos grupos políticos em detrimento de outros, e os motivos para tanto. Tal questão será discutida a partir de autores de estudos da tecnologia, da teoria social e da psicanálise. Não necessariamente inferindo uma diferenciação de conteúdo de ideologias políticas, propomos essa distinção considerando que os impactos subjetivos e de mobilização produzidos por tais mídias podem ser assimilados e empregados de acordo com objetivos específicos. Trata-se, assim, de um exame sobre os impactos que as mídias sociais produzem em processos de subjetivação e de agrupamento, e seus efeitos políticos.


Resumos This paper explores political and social impacts present in the ten years since June 2013 demonstrations, emphasizing an specific factor: the role of social media in the political landscape and in mobilizing groups. We take as a central question the possibility that those digital tools are better explored by some political groups to the detriment of others, and the reasons that explain this difference. This question is developed with authors from the studies of technology, social theory, and psychoanalysis. Without necessarily assuming a content differentiation among political views, we propose their distinction considering that the subjective and the mobilizing impacts produced by these media can be assimilated and employed according to specific objectives. Therefore, this study is an examination of the impacts that social media produce on subjectivation and grouping processes, and their political effects.


Cet article explore certains des impacts politiques et sociaux constatés au cours des dix années qui ont suivi les manifestations de juin 2013, en mettant l'accent sur un facteur spécifique: le rôle des médias sociaux dans le paysage politique et dans la mobilisation des groupes. À partir de là, il aborde la possibilité que ces outils numériques puissent être mieux exploités par certains groupes politiques au détriment d'autres, et les raisons de cette différence supposée. Cette question sera discutée à l'aide d'auteurs issus des études technologique, de la théorie sociale et de la psychanalyse. Sans nécessairement en déduire une différenciation dans le contenu des opinions politiques, nous proposons cette distinction en considérant que les impacts subjectifs et mobilisateurs produits par ces médias peuvent être assimilés et utilisés en fonction d'objectifs spécifiques. Il s'agit donc d'examiner les impacts que les médias sociaux produisent sur les processus de subjectivation et de regroupement, et leurs effets politiques.

RESUMO

BACKGROUND: Autosomal dominant polycystic kidney disease (ADPKD) is the most common genetic cause of chronic kidney disease (CKD) that requires dialysis. Knowing geographical clusters can be critical for early diagnosis, progression control, and genetic counseling. The objective was to establish the prevalence, geographic location, and ethnic groups of patients with ADPKD who underwent dialysis or kidney transplant in Colombia between 2015 and 2019. METHODS: We did a cross-sectional study with data from the National Registry of Chronic Kidney Disease (NRCKD) managed by the High-Cost Diseases Fund (Cuenta de Alto Costo [CAC] in Spanish) between July 1, 2015, and June 30, 2019. We included Colombian population with CKD with or without renal replacement therapy (RRT) due to ADPKD. Crude and adjusted prevalence rates were estimated by state and city. RESULTS: 3,339 patients with ADPKD were included, period prevalence was 9.81 per 100,000 population; there were 4.35 cases of RRT per 100,000 population, mean age of 52.58 years (± 13.21), and 52.78% women. Seventy-six patients were Afro-Colombians, six were indigenous, and one Roma people. A total of 46.07% began scheduled dialysis. The highest adjusted prevalence rate was in Valle del Cauca (6.55 cases per 100,000 population), followed by Risaralda, and La Guajira. Regarding cities, Cali had the highest prevalence rate (9.38 cases per 100,000 population), followed by Pasto, Medellin, and Bucaramanga. CONCLUSIONS: ADPKD prevalence is lower compared to Europe and US; some states with higher prevalence could be objective to genetic prevalence study.

RESUMO

Electrochemical sensors consisting of screen-printed electrodes (SPEs) are recurrent devices in the recent literature for applications in different fields of interest and contribute to the expanding electroanalytical chemistry field. This is due to inherent characteristics that can be better (or only) achieved with the use of SPEs, including miniaturization, cost reduction, lower sample consumption, compatibility with portable equipment, and disposability. SPEs are also quite versatile; they can be manufactured using different formulations of conductive inks and substrates, and are of varied designs. Naturally, the analytical performance of SPEs is directly affected by the quality of the material used for printing and modifying the electrodes. In this sense, the most varied carbon nanomaterials have been explored for the preparation and modification of SPEs, providing devices with an enhanced electrochemical response and greater sensitivity, in addition to functionalized surfaces that can immobilize biological agents for the manufacture of biosensors. Considering the relevance and timeliness of the topic, this review aimed to provide an overview of the current scenario of the use of carbonaceous nanomaterials in the context of making electrochemical SPE sensors, from which different approaches will be presented, exploring materials traditionally investigated in electrochemistry, such as graphene, carbon nanotubes, carbon black, and those more recently investigated for this (carbon quantum dots, graphitic carbon nitride, and biochar). Perspectives on the use and expansion of these devices are also considered.

RESUMO

To help meet the global demand for reliable and inexpensive COVID-19 testing and environmental analysis of SARS-CoV-2, the present work reports the development and application of a highly efficient disposable electrochemical immunosensor for the detection of SARS-CoV-2 in clinical and environmental matrices. The sensor developed is composed of a screen-printed electrode (SPE) array which was constructed using conductive carbon ink printed on polyethylene terephthalate (PET) substrate made from disposable soft drink bottles. The recognition site (Spike S1 Antibody (anti-SP Ab)) was covalently immobilized on the working electrode surface, which was effectively modified with carbon black (CB) and gold nanoparticles (AuNPs). The immunosensing material was subjected to a multi-technique characterization analysis using X-ray diffraction (XRD), transmission electron microscopy (TEM), and scanning electron microscopy (SEM) with elemental analysis via energy dispersive spectroscopy (EDS). The electrochemical characterization of the electrode surface and analytical measurements were performed using cyclic voltammetry (CV) and square-wave voltammetry (SWV). The immunosensor was easily applied for the conduct of rapid diagnoses or accurate quantitative environmental analyses by setting the incubation period to 10 min or 120 min. Under optimized conditions, the biosensor presented limits of detection (LODs) of 101 fg mL-1 and 46.2 fg mL-1 for 10 min and 120 min incubation periods, respectively; in addition, the sensor was successfully applied for SARS-CoV-2 detection and quantification in clinical and environmental samples. Considering the costs of all the raw materials required for manufacturing 200 units of the AuNP-CB/PET-SPE immunosensor, the production cost per unit is 0.29 USD.

RESUMO

Silver materials are known to present excellent properties, such as high electrical and thermal conductivity as well as chemical stability. Silver-based inks have drawn a lot of attention for being compatible with various substrates, which can be used in the production uniform and stable pseudo-reference electrodes with low curing temperatures. Furthermore, the interest in the use of disposable electrodes has been increasing due to the low cost and the possibility of their use in point-of-care and point-of-need situations. Thus, in this work, two new inks were developed using Ag as conductive material and colorless polymers (nail polish (NP) and shellac (SL)), and applied to different substrates (screen-printed electrodes, acetate sheets, and 3D-printed electrodes) to verify the performance of the proposed inks. Measurements attained with open circuit potential (OCP) attested to the stability of the potential of the pseudo-reference proposed for 1 h. Analytical curves for ß-estradiol were also obtained using the devices prepared with the proposed inks as pseudo-references electrodes, which presented satisfactory results concerning the potential stability (RSD < 2.6%). These inks are simple to prepare and present great alternatives for the development of pseudo-reference electrodes useful in the construction of disposable electrochemical systems.

RESUMO

OBJECTIVES: This study aimed to compare the analgesic effect between carprofen and grapiprant every 12 or 24 h on postoperative pain in cats undergoing ovariohysterectomy, in addition to the effects on the hematological, biochemical and urinalysis variables. METHODS: A total of 32 female cats were randomly divided into three groups, according to the treatment administered with the first dose given orally 90 mins before surgery, as follows: CAR (cats received 4 mg/kg carprofen, n = 11); GRA1 (cats received 2 mg/kg grapiprant, n = 10); and GRA2 (cats received 2 mg/kg grapiprant q12h, n = 11). Pain was assessed by UNESP-Botucatu Multidimensional Composite Pain Scale (UNESP) and Glasgow Feline Composite Measure Pain Scale (GLASGOW) for cats preoperatively (baseline) and at 1, 3, 6, 8, 12 and 24 h after extubation. Venous blood was collected at baseline, and 12 and 24 h after the administration of carprofen or grapiprant to perform a complete blood count (CBC), the percentage of Heinz bodies and serum biochemistry (alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, gamma-glutamyltransferase, creatinine and urea). Urinalysis was performed at baseline and 24 h after extubation. Glucose levels were evaluated at baseline and 1 h postoperatively. RESULTS: Pain scores were not significantly different among groups in both scales, although pain was higher at 3 h in comparison with 24 h in all groups. In the GRA1 and GRA2 groups, 67% (14/21) of cats needed rescue analgesia compared with 18% (2/11) in the CAR group. Glucose increased from baseline to 1 h in the GRA1 and GRA2 groups. None of the CBC, serum biochemistry and urinalysis variables differed among groups. CONCLUSIONS AND RELEVANCE: Grapiprant did not promote adequate analgesia during the first 3 h postoperatively in cats undergoing ovariohysterectomy compared with carprofen, and no benefits were observed by administering grapiprant every 12 h.

RESUMO

A Depressão Pós-Parto Materna (DPP) é uma condição clínica que acarreta efeitos negativos na saúde da mãe, do bebê, e na relação entre ambos. Intervenções neste contexto devem ser adaptadas à realidade, a fim de diminuir os impactos no desenvolvimento infantil e na saúde materna. O objetivo deste estudo foi a construção de um protocolo de psicoeducação e a elaboração de um treinamento de reconhecimento de emoções. O método se constituiu de quatro etapas: revisão da literatura, proposta preliminar, análise de especialistas e estudo piloto. A psicoeducação foi guiada por sete cartilhas com temáticas típicas do desenvolvimento, e o treinamento de reconhecimento de emoções foi composto por um protocolo de atendimento para mães com DPP e seus bebês, com o objetivo de trabalhar questões relativas ao processamento de faces materno e viés atencional. Os resultados demonstraram que as duas propostas de protocolo de intervenção se mostraram de fácil compreensão para os sujeitos avaliados.


Postpartum Maternal Depression (PPD) is a clinical condition that has negative effects on the health of the mother, the baby and the relationship between both. Interventions in this context must be adapted to reality in order to reduce the impacts on child development and maternal health. The aim of this study was to build a psychoeducational protocol and to develop an emotion recognition training. The method consisted of four stages: literature review, preliminary proposal, expert analysis and pilot study. Psychoeducation was guided by seven booklets with themes typical of development, and the emotion recognition training consisted of a care protocol for mothers with PPD and their babies, with the objective of working on issues related to the processing of maternal faces and attentional bias. The results showed that the two intervention protocol proposals proved to be easy to understand for the evaluated subjects.

RESUMO

AIM: This study relates the average number of nucleolar organizing regions (NORs) obtained in a series of cases of oral leukoplakia, with three methods of histopathological classification of such lesion. MATERIALS AND METHODS: This is a histopathological-histochemical laboratory cross-sectional study. The 18 cases of leukoplakia analyzed were filed at Pathology Service of the Biological Sciences Institute of the University of Passo Fundo, Rio Grande do Sul, Brazil (SDH/ICB/UPF) (2017 and 2018), from which epidemiological data were extracted. New histological sections were performed for impregnation by the argyrophilic nucleolar organizer regions (AgNOR) technique. The histopathological slides were analyzed by photon microscopy (1,000×), and the nuclei of 100 epithelial cells were photographed to count the number of NORs. Three methods were used for the lesions' histopathological classification [World Health Organization (WHO), Brothwell, and binary system]. The means of NORs were compared with the three histopathological classifications by means of the t or analysis of variance (ANOVA) statistical tests, at a significance level of 5%. RESULTS: According to the WHO classification method, most cases (11-61.1%) had a moderate classification. Evaluations by the Brothwell method showed moderate and mild classification in 50 and 38.9% of cases, respectively. According to the binary system, most cases (10-55.6%) had low risk. The average NORs found in 100 nuclei of each of the 18 lesions ranged from 2 to 4. When crossing the average NORs with the histopathological classification methods of the lesions by means of the t test or ANOVA, no significant relationship was noted. CONCLUSION: The average of NORs is not associated with the histological classifications of leukoplakias. Thus, the AgNOR method should be used with caution when differentiating different histological grades of leukoplakias. CLINICAL SIGNIFICANCE: The AgNOR method should be used with caution to determine the clinical treatment of oral leukoplakias, since no agreement was observed between this method and the histopathological classifications available for such lesion.

RESUMO

Disposable electrochemical sensors using sustainable and cheap materials are an exciting alternative to produce new kinds of sensing platforms. Waterproof paper (WP) is a biodegradable and biocompatible material that allows dropped of the sample on its surface without absorption by fibers. Also, WP can be used for miniaturized sensors construction. In this work, a conductive ink was produced with nail polish and graphite powder, using the WP as the sensor substrate for paracetamol (PAR) and melatonin (MEL) voltammetric determination. PAR is a pharmaceutical commonly used in high doses for the relief of pain and fever, and MEL is a hormone related to several diseases besides a direct relation to sleep quality. Using differential pulse voltammetry for PAR determination, the WP sensor showed a linear response in the concentration ranging from 0.50 µmol L-1 to 100 µmol L-1 with a limit of detection (LOD) of 53.6 nmol L-1. Square wave voltammetry was applied for MEL determination, and the proposed electrode presented linear response ranging from 0.80 µmol L-1 to 100 µmol L-1 and LOD of 32.5 nmol L-1. The sensor showed excellent repeatability and reproducibility for consecutive measurements. Then, the disposable WP sensor was successfully applied in the determination of PAR and MEL in pharmaceutical and biological samples, with recovery values, above 91.1%. The described architecture allowed the manufacture of a disposable, simple, and low-cost electroanalytical device that can be used for electrochemical sensing.

RESUMO

Yellow fever (YF) surveillance in Brazil is focused mainly on the detection of epizootic events regarding New World non-human primates (NWNHP). We present a challenging case of a Callitrichidae (Callithrix spp) kept as a domiciliated pet that lived in the urban area of São Paulo municipality and was positive to YF virus by RT-qPCR and immunohistochemistry. After investigation, it was the first occurrence of non-autochthonous YF case of NWNHP described, with probable place of infection in the North shore of São Paulo state. This case illustrates the importance of coordinated laboratorial and field actions, and risks posed by transit of wildlife.

RESUMO

Background: Primary splenic torsion occurs when there is a splenic vascular pedicle rotation without association of otherdiseases, as the Gastric Dilatation Volvulus (GDV). Accessory spleen consists in a splenic tissue fraction independentfrom main organ, caused by a spleen defect in the embryonic development, most remaining asymptomatic and discoveredincidentally. They have their own blood supply, which is usually from a branch of the splenic artery. Present report represents a primary splenic torsion with the accessory spleen finding in a dog.Case: A 7-year-old female mongrel was referred to Veterinary Hospital of Universidade Federal do Rio Grande do Sul,showing pain and firm consistency in the left abdominal region, prostration and inappetence four days before the medicalappointment. At the clinical examination, the patient was alert, 7% dehydration, hypocorous mucous membranes, withoutalteration in lymph nodes, left abdominal pain. Laboratory tests, chest radiographic and abdominal ultrasound was requested.Two images compatible with splenic image were visualized, one with a regular structure without vascularization suggestingsplenic torsion and another with homogeneous parenchyma and echogenicity of the normal spleen, with vascularizationsignal. The animal was referred to the surgical procedure and the anesthetic induction protocol with propofol (6 mg/kg-1)and ketamine hydrochloride (2 mg/kg-1) and maintenance with total intravenous anesthesia with propofol (0.2-0.4 mg/kg-1/min) and lidocaine (2 mg/kg-1), in a semi-closed loop and spontaneous ventilation. The pre-retro-umbilical incision in theventral midline was performed, and the exploratory celiotomy was done. During the cavity exploring, a small amount of freefluid and a structure compatible with the spleen were observed. It was noted that the splenic vascular pedicle was twistedaround its axis and the gastroesplenic and splenocolic ligaments were also involved...(AU)

RESUMO

Enfermidade crônica, transmissível e negligenciada, a hanseníase possui indicadores alarmantes e, quando não diagnosticada e tratada precocemente, leva a ocorrência de incapacidades físicas permanentes. Somadas às tantas complicações possíveis da hanseníase, as incapacidades podem interferir de maneira significativa na vida do indivíduo, prejudicando o desenvolvimento de suas atividades do dia a dia, como as laborativas. A redução da capacidade para o trabalho, causada pela doença, compromete a produtividade, podendo levar a interrupção do trabalho, afastando ou, até mesmo, excluindo definitivamente indivíduos da cadeia produtiva. O afastamento do trabalho por motivo de doença possui repercussões financeiras e psicossociais ao trabalhador. Esse estudo objetivou analisar a correlação da hanseníase com o afastamento do trabalhador que realiza tratamento na Unidade Básica de Saúde. Trata-se de um estudo transversal, analítico com abordagem quantitativa, realizado em 10 unidades de saúde notificadoras de hanseníase do município de Belém-Pará. Foram selecionados 72 pacientes com diagnóstico de hanseníase, com idade igual ou superior a 18 anos e que possuíam alguma atividade trabalhista, independente do vínculo empregatício. A amostra foi composta por trabalhadores com média de idade de 42,9 anos, 69,4% do sexo masculino, 45,8% com nível de escolaridade fundamental, renda mensal de 1 a 3 salários mínimo (59,7%), ocupando cargos de trabalhadores dos serviços, vendedores do comércio em lojas e mercados (31,9%). Foi evidenciada predominância da forma clínica Dimorfa (72,2%), sem nervos afetados (52,8%) e, com 5 a 10 lesões cutâneas (51,3%). Foi identificada presença de incapacidades físicas em 34,7% dos trabalhadores, sendo esta, a principal causa indicada para os afastamentos do trabalho, problema referido por 59,7% dos trabalhadores. Outros problemas relacionados aos afastamentos do trabalho, indicados pelos trabalhadores foram: restrição ao trabalho (56,9%), redução da capacidade laborativa (55,5%), omissão do diagnóstico da doença (43%), falta de readaptação/mudança de função (90,2%) e preconceito (26,3%). O tempo de afastamento do trabalho em decorrência da hanseníase foi superior a 6 meses em 48,8% dos casos. Na análise bivariada identificou-se relação estatística com o afastamento do trabalho entre: redução da capacidade laborativa (p< 0.000), restrição ao trabalho (p=0.0001), maior número de nervos afetados (p=0.0015), presença de episódios reacionais (p=0.0086). Percebeu-se que, os afastamentos do trabalho estiveram relacionados, com maior grau de significância, às formas multibacilares da doença, aos trabalhadores com baixo índice de escolaridade, ocupando funções que exigem baixo ou nenhum conhecimento técnico, no setor informal de trabalho. Conclui-se que existe relação significativa entre a hanseníase e o afastamento do trabalho do paciente em acompanhamento na Unidade Básica de Saúde e que, a presença de incapacidades físicas, é considerada a principal causa de afastamento do trabalhador. É necessária maior articulação entre as estratégias de atenção à hanseníase e a saúde do trabalhador para a proposição de medidas que visem a minimização de afastamentos do trabalho em decorrência da doença


Chronic, transmissible and neglected disease, leprosy has alarming indicators and, when not diagnosed and treated early, leads to the occurrence of permanent physical disabilities. In addition to the many possible complications of leprosy, disabilities can significantly interfere with the individual's life, hampering the development of their day-to-day activities, such as work activities. The reduction of work capacity, caused by the disease, compromises productivity, which can lead to interruption of work, distancing or even definitively excluding individuals from the productive chain. The work leave due to illness has financial and psychosocial repercussions on the worker. This study aimed to analyze the correlation of leprosy with the removal of the worker who is being treated at the Basic Health Unit. This is a transversal, analytical study with a quantitative approach carried out in ten health units reporting leprosy in the city of Belém - Pará. Were selected 72 patients with a diagnosis of leprosy, aged 18 years or more and who had some labor activity, regardless of the employment relationship. The sample consisted of workers with a mean age of 42.9 years, 69.4% male, 45.8% with a primary schooling level, monthly income of 1 to 3 minimum wages (59.7%), occupying positions of service workers, store sellers and markets (31.9%). It was evidenced predominance of the clinical form Dimorfa (72.2%), without affected nerves (52.8%) and with 5 to 10 cutaneous lesions (51.3%). The presence of physical disabilities was identified in 34.7% of the workers, being this the main cause indicated for work leave, a problem referred by 59.7% of the workers. Other problems related to work leave, indicated by workers were: work restriction (56.9%), reduction of work capacity (55.5%), omission of the diagnosis of the disease (43%), lack of readaptation change of function (90.2%) and prejudice (26.3%). The time to leave work due to leprosy was greater than 6 months in 48.8% of the cases. In the bivariate analysis we identified a statistical relationship with the work away from: reduction of labor capacity (p <0.000), work restriction (p = 0.0001), higher number of nerves affected (p = 0.0015), presence of reactive? episodes (p = 0.0086). It was observed that the work leave was related, with greater degree of significance, to multibacillary forms of the disease, to workers with low educational level, occupying functions that require little or no technical knowledge in the informal work sector. It is concluded that there is a significant relationship between leprosy and the patient's absence from work in the Basic Health Unit and that the presence of physical disabilities is considered the main cause of the worker's absence. Greater articulation between the strategies of attention to leprosy and the health of the worker is necessary for the proposition of measures that aim at the minimization of absences from work due to the disease

RESUMO

The envisaged ubiquitous sensing and biosensing for varied applications has motivated materials development toward low cost, biocompatible platforms. In this paper, we demonstrate that carbon nanodiamonds (NDs) can be combined with potato starch (PS) and be deposited on a glassy carbon electrode (GCE) in the form of a homogeneous, rough film, with electroanalytical performance tuned by varying the relative ND-PS concentration. As a proof of concept, the ND/PS film served as matrix to immobilize tyrosinase (Tyr) and the resulting Tyr-ND-PS/GCE biosensor was suitable to detect catechol using differential pulse voltammetry with detection limit of 3.9 × 10-7 mol L-1 in the range between 5.0 × 10-6 and 7.4 × 10-4 mol L-1. Catechol could also be detected in river and tap water samples. This high sensitivity, competitive with biosensors made with more sophisticated procedures and materials in the literature, is attributed to the large surface area and conductivity imparted by the small NDs (<5 nm). In addition, the ND-PS matrix may have its use extended to immobilize other enzymes and biomolecules, thus representing a potential biocompatible platform for ubiquitous biosensing.
