Epoxy is often used as important material for cryogenic engineering, and can be designed to meet these high standards for cryogenic applications. CNT plays a vital role in reinforcement in polymers. In this experimental study explores the wear and hardness characteristics of epoxy reinforced with nanocomposite Multiwall Carbon nanotubes (MWCNT) and Aluminium Oxide (Al2O3)after the cryogenic treatment process. The specimens are prepared by varying the weight percentage of 1, 1.5 and 2% with the help sonication process. The wear properties were examined by pin on disc apparatus in dry sliding condition under different loads of 10, 20 and 30N respectively. The field emission scanning electron microscopy (FESEM) is used to understand the surface morphology of cryogenically treated and untreated samples. Hardness properties were examined by Barcol testing machine as per ASTM Standard. The results revealed that 1.5 % addition of MWCNTs and Al2O3 gives better wear properties. Cryogenically treated sample of 1.5 % were shows better improvement of wear resistance and hardness up to 62 % and 45 % comparing untreated samples.

Bi2WO6 thin nanoplates were modified by 5% by weight of bimetallic Ag0.9Pd0.1 nanoparticles to form Schottky barrier by photoreduction method. The as‐synthesized heterostructure 5% Ag0.9Pd0.1/Bi2WO6 nanocomposites were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Fourier Transform Infrared Spectrophotometry (FTIR) and Raman spectroscopy. XRD pattern of heterostructure 5% Ag0.9Pd0.1/Bi2WO6 nanocomposites showed only orthorhombic Bi2WO6 structure due to the low loading content and small particle size of bimetallic AgPd nanoparticles. TEM image of heterostructure 5% Ag0.9Pd0.1/Bi2WO6 nanocomposites shows a number of sphere-like bimetallic AgPd nanoparticles embedded on top of Bi2WO6 thin nanoplates. The photocatalytic activities of pure Bi2WO6 sample and heterostructure 5% Ag0.9Pd0.1/Bi2WO6 nanocomposites were studied through the photodegradation of rhodamine B (RhB) under visible light irradiation. The heterostructure 5% Ag0.9Pd0.1/Bi2WO6 nanocomposites show photodegradation of RhB under visible light irradiation higher than pure Bi2WO6 nanoplates. The enhanced photocatalytic properties of the heterostructure 5% Ag0.9Pd0.1/Bi2WO6 nanocomposites are attributed to the efficient separation of photoinduced carriers at the interface of bimetallic Ag0.9Pd0.1 nanoparticles and Bi2WO6 nanoplates. A possible photocatalytic mechanism is also proposed according the experimental results.

The transmittance spectra are measured and the optical constants were determined. The measurements showed that the optical constants reveal nonsystematic growing with loading ratio whereas they increase, decrease and return to increase after there. The electrical measurement showed that the A.C conductivity obeys the empirical formula σa.c(ω)=Aωs , where(s) lies between (0.78- 0.0013), σa.c(ω) declared frequency-dependent of the neat PMMA and PMMA doped with 0.06 G while it was frequency independent for all composites samples in hole frequency range. The Real and Imaginary Dielectric Constants showed progressive growth with the rise of the loading ratio.

This study involves the synthesis of gold nanoparticles (AuNPs) formed from the Prosopis farcta leaf extract. The transmission electron microscope, scanning electron microscope, atomic force microscope, X-ray diffraction, and UV-Visible spectroscopy results all confirmed the characterisation of AuNPs. The in vitro anticancer activity of AuNPs against breast cancer -13 (AMJ-13) and human breast epithelial (HBL) cell lines was investigated, along with its antibacterial activity against gram's positive bacteria, the Staphylococcus aureus. AuNPs were found to produce a significant cytotoxic effect on the AMJ-13 cell line, contrary to the HBL cell line, which showed no significant cytotoxicity upon it. The antibacterial activity demonstrated that gram-positive S. aureus was affected by AuNPs. These results prove that AuNPs have great potential as anticancer and antibacterial agents and can be used in developing strategies for successful anticancer and antibacterial.

Cubic silicon carbide (3C-SiC) is successfully synthesized through a simple solid-state reaction technique at a comparatively low temperature without using any catalyst. The XRD data is also used to study other structural parameters of synthesized sample by using different method. Raman peak at 796 cm-1 supports the XRD results. Si–C vibrational mode observed at 788 cm-1 in the FTIR spectrum further confirms the growth of 3C-SiC. UV-Vis spectroscopy is used to measure optical bandgap energy (Eg = 2.36 eV). Other optical parameters such as dielectric constant and refractive index of grown sample are also studied. Electrical performance is analyzed by using graphene contact with further evaluation of dark and light IV-measurements. The use of graphene contact establishes the enhancement of electrical conductivity of as-grown samples particularly when they are exposed to light. These findings indicate that the grown sample has comparatively better transport properties than conventional metal contacts under the illuminated conditions.

Graphical Abstract

Background

This study aims to study the histomorphological response of d-ribose-l-cysteine (DRLC) to ketamine-induced testicular damage in adult male Wistar rats.

Methods

A total of 20 adult male Wistar rats were used for this experiment. The animals were randomly divided into four groups (A–D) (n = 5). Group A served as the control, receiving distilled water as placebo; animals in group B were administered with 50 mg/kg body weight (bw) of ketamine only; animals in group C were administered with 50 mg/kg bw of ketamine and 30 mg/kg bw of DRLC; animals in group D were administered with 30 mg/kg bw of DRLC only. At the end of the experiment, blood was taken from the heart via cardiac puncture and stored, semen was collected from the caudal epididymis for immediate sperm analysis, while the testes were excised and preserved for histological examination and biochemical analysis.

Results

The results showed abnormalities marked by a significant decrease in the weights, sperm parameters, as well as antioxidants, serum hormonal levels and abnormal testicular microarchitecture in the rats as a result of ketamine treatment. However, DRLC exhibits significant quenching effects and attenuating activities on the ketamine-induced abnormalities by increasing the rats' weights, restoring the sperm parameters, as well as increasing the antioxidants and serum hormonal levels with restored testicular histoarchitecture.

Conclusion

DRLC in the current study attenuated the toxic effects of ketamine on the testes; therefore, it could be used as adjuvant therapy for reproductive toxicant-induced testicular toxicity due to its potent antioxidant property.

Significance statement

The testis is a vital secreting organ that produces and stores spermatozoa and is crucial for producing male sexual hormones and is thus the main target of infertility when overdoses of chemicals and toxins are introduced to it. In view of the facts above, studies of the potential of chemicals like ketamine to induce testicular toxicity are important as well as the methods aimed at mitigating this effect. Various studies have been conducted on the effectiveness of DRLC in subsiding different chronic health conditions, but there is no published literature on the effects of DRLC in ketamine-induced testicular toxicity in adult male Wistar rats. Hence we present this study.
Pendimethalin exposure disrupts mitochondrial function and impairs processes related to implantation

Published: February 2023

In brief

Pendimethalin as a dinitroaniline herbicide is used to eliminate weeds during the cultivation of various crops such as grains, fruits, and vegetables. This study reveals that pendimethalin exposure at various concentrations led to disruption in Ca2+ homeostasis and mitochondrial membrane potential, as well as dysregulation of the mitogen-activated protein kinase signaling pathway and implantation-related genes in porcine trophectoderm and uterine luminal epithelial cells.

The use of herbicides is a major control method in agriculture. Pendimethalin (PDM) has been increasingly used as a herbicide for approximately 30 years. PDM has been reported to cause various reproductive problems, but its toxicity mechanism in the pre-implantation stage has not been investigated in detail. Herein, we studied the effects of PDM on porcine trophectoderm (pTr) and uterine luminal epithelial (pLE) cells and identified a PDM-mediated anti-proliferative effect in both cell types. PDM exposure generated intracellular reactive oxygen species, induced excessive Ca2+ influx into mitochondria, and activated mitogen-activated protein kinase signaling pathway. Ca2+ burden resulted in the dysfunction of mitochondria and eventual disruption of Ca2+ homeostasis. Further, PDM-exposed pTr and pLE cells showed cell cycle arrest and programmed cell death. In addition, a decrease in migration ability and dysregulated expression of genes related to the functioning of pTr and pLE cells was evaluated. This study provides insight into time-dependent transitions within the cell environment after PDM exposure and elucidates a detailed mechanism of induced adverse effects. These results imply that PDM exposure can potentially cause toxic effects on the implantation-related process in pigs. Moreover, to the best of our knowledge, this is the first study to describe the mechanism by which PDM induces these effects, enhancing our understanding of the toxicity of this herbicide.

Pancreatic Intraductal Papillary Mucinous Neoplasms: A Narrative Review
Authors: Paramythiotis Daniel , Karlafti Eleni , Fotiadou Georgia , Charalampidou Maria , Karakatsanis Anestis , Ioannidis Aristeidis , Michalopoulos Antonios
Published: February 2023

Introduction: Intraductal papillary mucinous neoplasms (IPMNs) are the most frequent cystic pancreatic neoplasm. They derive from the main pancreatic duct or branch ducts.

Aim: This narrative review aims to present and compare the current guidelines on the management of IPMNs.

Materials and methods: We reviewed the most important scientific literature on the management of IPMNs.

Discussion: The clinical presentation of IPMNs is usually non-specific; common symptoms are abdominal pain, weight loss, and jaundice. There are no sex differences, and the incidence increases with age. It is considered a premalignant lesion associated with synchronous or metachronous carcinomas. Multifocal sites within the pancreas and the presence of solid components, like mural nodules, are predictive factors for developing malignancy. Magnetic resonance imaging (MRI) is the imaging technique of choice. However, computed tomography (CT) and endoscopic ultrasound (EUS) with fine-needle aspiration (FNA) can also contribute to the diagnosis. Resection is the optimal treatment for IPMNs that arise from the main duct, while several indications are suggested for the surgery on IPMNs of branch ducts.

Conclusion: The decision on surgery is not always a simple task and should be based on high-risk features of the neoplasm. In any case, re-examination and follow-up are highly recommended.
Safety and efficacy of Fibroquel® (polymerized type I collagen) in adult outpatients with moderate COVID-19: an open-label study
Authors: Castro-Rocha MD Hilda Adriana
Published: February 2023

Background: SARS-CoV-2 infection induces a hyperinflammatory syndrome, causing acute respiratory distress syndrome, and clinical deterioration. The current therapeutic investigation has been focusing on the development of novel immunosuppressant therapies to control cytokine production. Objective: To evaluate the safety and clinical effect of intramuscular administration of polymerized type I collagen in adult outpatients with moderate COVID-19. Design, setting, and participants: This was an open-label study that recruited 20 adult patients with confirmed COVID-19 diagnosis, from June 16, 2020 to September 20, 2020. The final date of follow-up was November 4, 2020. Interventions: Patients received intramuscularly 1.5 ml of polymerized type I collagen (12.5 mg of collagen) every 12 h for 3 days and then every 24 h for 4 days. Main outcomes and measures: The primary outcome was oxygen saturation >92% on room air without supplemental oxygen. The secondary outcome was the duration of symptoms. Results: Of 20 patients who were recruited, 9 (45%) were male, with mean age of 49.5±11.2 years. Oxygen saturation >92% on room air without supplemental oxygen was achieved by 18 (90%) and 19 (95%) of patients at day 1 and 8 post-treatment with polymerized type I collagen (P=0.001). Most of the symptoms improved from day 3 of treatment concerning baseline. The neutrophil-to-lymphocyte ratio (NLR) and lactate dehydrogenase (LDH) (predictive biomarkers for moderate-severe COVID-19) decreased to statistically significant levels at day 8 post-treatment (P=0.023 and P=0.011, respectively). No serious adverse events were detected. Conclusion and relevance: In the study more than 90% of the patients had mean oxygen saturation >92%. A shorter duration of the symptoms was determined. A significant decrease in NLR and LDH was also found. The study is limited by small sample size and short follow-up duration, and determination of clinical efficacy would require larger randomized trials with more definitive outcome measures.

One of the reasons of losses of the electric power caused by imperfection of means of its account is revealed. The analysis of errors of means of the account of active and reactive energy in the conditions of work of a network in low-sine and low-sine modes is executed. The dependences of the angular errors of the means of measuring active and reactive energy are found. The graph of the change of the angular error of the active energy meter in the range of phase shift angles between voltage and current from -2 to 2 and the graph of the angular error of the reactive energy meter in the range of phase shift angles be-tween voltage and current from -0 degrees to are presented. The loss of active energy due to imperfection of active energy meters reaches infinity under the conditions of approaching the phase shift angle between current and voltage vectors to 2, and the loss of reactive energy reaches infinity under the conditions of approaching the phase shift between current and volt-age vectors to  are shown. The errors of active energy measurement are calculated, which indicate the unsuitability of elec-tricity meters manufactured in accordance with existing standards for metering of electricity in low-cosine modes of network operation.

Published: February 2023

Objectives

Routine human papillomavirus (HPV) vaccination has been recommended in the United States since 2006 but rates remain suboptimal. State-based studies suggest that initiation in late childhood at ages 9 to 10 years compared with the recommended early adolescent ages of 11 to 12 years improves series completion. No study with national scope has explored the early initiation-HPV series completion relationship. This study addresses this knowledge gap and explores whether early initiation might improve series completion by increasing time to target completion age (time pathway) or by moving initiation to an earlier developmental stage (development pathway).

Methods

Using data from the National Immunization Survey-Teen 2017-2020, a retrospective cohort of 19 575 15 to 17 year olds who initiated HPV vaccination between ages 9 and 12 years was assembled. Time pathway endpoints were series completion by ages 13 and 15 years. The development pathway endpoint was completion within 3 years of initiation.

Results

Early initiators were more likely to complete by ages 13 (74.0% vs 31.1%, P < .001) and 15 (91.7% vs 82.7%, P < .001) years but less likely to complete within 3 years (82.3% vs 84.9%, P = .007). The association of early initiation to completion was maintained in multivariable analyses for time pathway endpoints (age 13 years adjusted odds ratios [AOR] = 6.16; 95% confidence interval [CI], 5.45–6.96, age 15 years = AOR 2.56; 95% CI, 2.14–3.14) but not the development pathway endpoint (AOR = 0.93; 95% CI, 0.80–1.07).

Conclusions

Moving routine HPV vaccination to ages 9 to 10 may improve vaccination coverage rates in early and mid-adolescence. Providers should be vigilant to patient interactions after HPV series initiation to optimize public health benefits of vaccination.

The outbreak of the Covid 19 pandemic had a major impact on Indonesia's economic growth. One of the sectors affected is tourism. To boost the tourism industry, we must not forget the Small and Medium Enterprises (SME) which are one of its supporters. During this pandemic, as many as 75% of SMEs had experienced a significant decline in sales. Most of these business actors apparently do not have a planning strategy for dealing with a disaster (disaster preparedness plan). In fact, this capability can help them prepare for business sustainability both during and after the pandemic. Therefore, the aim of this community service is to increase the empowerment of SME’s HR in order to improve the welfare of community-based tourism in Yogyakarta and Lombok. In general, the stages of activity are divided into two, namely 1) mapping SME’s entrepreneurs; 2) implementation of the online and offline training and mentoring program on entrepreneurial competence. The output expected from this activity is to select young entrepreneurs from each region who will later be given the opportunity to follow pitching and match making events with angel capital (entrepreneurs, CSR, local government, or banking). Meanwhile, the results of this activity are independent entrepreneurs who can become the driving force in their community

The diffusivity values of C in pure Zr and in Zr containing dissolved O (Zr(O)) were determined in a temperature range of 623–1023 K for Zr and 923–1123 K for Zr(O) from depth profiles of C obtained by glow-discharge emission spectroscopy. The C diffusivity in Zr(O) decreased as the O concentration in Zr increased and that for Zr containing 15 at % O was two orders of magnitude smaller than that for pure Zr. One-dimensional numerical calculations of Fick’s diffusion equation with a Soret effect indicated various non-uniform distributions of C in a 5-mm-thick Zr matrix under a temperature gradient of 573 to 773 K for 3 years, assuming a heat of transport of − 1.5 to + 1.5 eV. Isothermal annealing at 773 K for 10 years could result in a uniform distribution, whereas dissolution of O in the interstitials of the Zr matrix would hinder C transport through the interstitials.

Graphical Abstract

As concentration of O increased in HIP Zr by 15 at%, the diffusivity of C decreased more than two orders of magnitude.

Due to the high levels of pollution load produced in the leather industry, many studies are being conducted to replace most of the hazardous chemicals used. One of the options is to use enzymes which are biodegradable and considered environmentally friendly. Hides and skins contain many non-collagenous substances that require specific enzymes to remove. The aim of the study was to evaluate the effectiveness of different enzyme formulations in the unhairing process of goatskins. To achieve this, four types of enzymes were purchased from Jian Grace Industries which include amylase (100,000 U/g), protease (200,000 U/g), keratinase (200,000 U/g), and lipase (100,000 U/g). All possible combinations of one, two, three and four enzymes per formulation were prepared by mixing equal amounts per formulation. Parameters such as total solids, dissolved solids and protein content were determined on the affluent by standard procedures. In addition, the percentage weight gain, residual fat content and organoleptic test of the pelt were evaluated. Data were analysed using SPSS statistical packages version 21. ANOVA and t-test was used to test the level of significance (p≤ 0.05). Although several formulations gave complete unhairing, a formulation of keratinase, protease, and lipase (KPL) was selected as the best formulation. This formulation gave a completely unhaired pelt with a residual fat content of 6.4%. The organoleptic tests of all the unhaired pelts had a rating of 7-9. In conclusion, application of more than one enzyme can be a better option in removing non-collagenous components and in the replacement of the use of sodium sulphide in unhairing process.

In South Africa, as is globally, many people struggle with the challenges which emanate from developmental dyslexia (DD). It is thus important for educators to have adequate knowledge and a positive mindset regarding DD and the management thereof in the school context. One such important method of management is the accommodation of these learners in mainstream class. The quantitative survey study reported on here was aimed at determining the perspectives of educators in 2 private schools in the Tshwane South District, Gauteng, South Africa, regarding the knowledge of, attitude towards, and management of accommodations for learners with DD. We implemented a quantitative descriptive cross-sectional survey research approach where a self-administered questionnaire was administered after purposive sampling. Results indicate that the respondents, regardless of their qualifications, gender, or years of teaching experience, had limited knowledge of DD, but with a generally positive attitude towards inclusion and management of these learners. Furthermore, it was found that educators had an awareness of the terminology related to the accommodations that the education department granted these learners with DD. However, they were uncertain about the perceived path and nature of accommodations provided to learners. Specific details and related recommendations were explored.

Published: February 2023

RESUMO O artigo apresenta uma análise comparada de dez países selecionados sobre as relações entre governança participativa, perfis socioeconômicos e sistemas de saúde com resultados sanitários e de Indicadores de Governança Global. As fontes principais foram bases de dados produzidas e/ou compiladas pelo Banco Mundial. O modelo analítico se apoia em enfoque institucionalista para tratar de proteção social e governança participativa – esta, como utilizada, recobre as noções de participação social, porosidade governamental e regulação responsiva. Os resultados mostram uma sólida convergência entre perfis socioeconômicos mais distributivos, sistemas sanitários com maior financiamento público e universalismo e melhores indicadores de governança. Esta análise reforça os argumentos sobre trajetórias institucionais socialmente virtuosas e sujeitas a reforços positivos capazes de produzir melhores resultados sociais e políticos ao longo do tempo.
Participation, representation, and deliberation in the decision-making process of the Municipal Health Council of Marabá-PA (2018-2020)
Authors: Rocha Norberto Ferreira , Moreira Marcelo Rasga
Published: February 2023

ABSTRACT The objective of this article is to analyze the decision-making process of the Municipal Health Council of Marabá (CMS-M), in the state of Pará, in the period of 2018 to 2020, focusing on the themes that were discussed in the regular meetings that took place during such period. The case study was used as a research method with a qualitative approach that combines primary and secondary sources. The primary sources were obtained through participant observation in the meetings held at the CMS-M and the secondary sources through the analysis of public documents, especially ‘guidelines’ and ‘minutes’ produced. This method is linked to its analysis model, conceived within the scope of this article. As results, the following was found: effective participation of councilors in the deliberative process; institutional rules restricting society’s participation in filing claims and complaints; strong influence of municipal management in the decision-making process of the council; and low response from the municipal government in complying with the deliberations produced in the CMS-M.

RESUMO O objetivo do estudo foi analisar o perfil e as principais demandas apresentadas por jovens de 15 a 29 anos à Ouvidoria-Geral do Sistema Único de Saúde (SUS) do Ministério da Saúde. Foram extraídas as bases de dados ‘manifestações’ e ‘perfil cidadão’ do Sistema Informatizado OuvidorSUS, de 2014 a 2018. Os dados foram analisados segundo os canais de atendimento, classificação e tipificação. O perfil foi desagregado em idade, raça/cor, sexo, orientação sexual, escolaridade, ocupação e faixa de renda. Foram registradas 114.618 manifestações com perfil do cidadão, sendo que 15,17% possuíam entre 15 e 29 anos. Prevaleceram negros (pretos e pardos), mulheres, heterossexuais, com nível superior concluído ou em curso, renda de até 2 salários mínimos e empregados no setor privado. A maior parte das manifestações foram solicitações, seguidas de reclamações e denúncias. As solicitações majoritariamente eram de consultas e cirurgias, nas áreas de ginecologia e obstetrícia e ortopedia e traumatologia. As reclamações e denúncias referiam-se, em grande parte, à gestão, sobretudo a profissionais e estabelecimentos de saúde. As sugestões foram as menos frequentes. As demandas refletem, em geral, os serviços utilizados pelos jovens e devem ser consideradas pela gestão para o direcionamento de políticas de saúde adequadas a essa população.
Health demands of young Brazilians: profile and manifestations of the population aged 15 to 29 years to the SUS General Ombudsman (2014-2018)

ABSTRACT This study aimed to analyze the profile and the main demands presented by young people (15 to 29 years old) to the Unified Health System (SUS) General Ombudsman of the Ministry of Health of Brazil. The databases ‘manifestations’ and ‘citizen profile’ of the System were extracted from the OuvidorSUS computerized system, referring to the years 2014 to 2018. The data were analyzed according to the service channels, classification, and typification. The profile was disaggregated by age, race/color, gender, sexual orientation, education, occupation, and income. 114,618 manifestations were registered with the citizen’s profile, with 15.17% being by people from 15 to 29 years old. Blacks (including pardos), women, heterosexuals, with completed or ongoing higher education, income of up to 2 minimum wages, and employed in the private sector prevailed. Most of the manifestations were ‘requests’, followed by ‘complaints’ and ‘denunciations’. Most requests were for consultations and surgeries, in the areas of gynecology and obstetrics, and orthopedics and traumatology. Complaints and denunciations were largely related to management, especially to health professionals and establishments. The suggestions were the least frequent. The demands largely reflect the services used by young people and should be considered by managers to guide health policies appropriate to this population.
Sociedade, fobias e diferenças

Published: February 2023

RESUMO Este ensaio teve como objeto de análise as ‘identidades de gênero/sexualidade’, a partir de questões da chamada ‘pauta de costumes’, no século XXI. A discussão aqui proposta está articulada às necessidades sociais de saúde no amplo território brasileiro. Recorre-se ao pensamento de Foucault, Butler, Derrida e outros autores do espectro ‘pós-estruturalistas’, para refletir sobre a relação entre identidade e diferença e sua repercussão no controle sobre os corpos, em um contínuo processo discriminatório, com a conservação dos ciclos de violência e exclusão.

ABSTRACT This essay had as object of analysis the ‘gender identities/sexuality’, from issues of the so-called ‘customs agenda’, in the 21st century. The discussion proposed here is articulated to the social needs of health in the vast Brazilian territory. The thought of Foucault, Butler, Derrida, and other authors of the ‘post-structuralist’ spectrum, are used to reflect on the relationship between identity and difference, and its impact on the control over bodies, in a continuous discriminatory process with the perpetuation of the cycles of violence and exclusion.
Mecanismos de governança, instituições societárias e burocracia estatal: reflexões sobre instituições societárias e porosidade governamental
Authors: Ribeiro José Mendes
Published: February 2023

RESUMO Este ensaio discute os mecanismos de governança participativa no setor público a partir de teorias sobre liberdades civis, democracias dialógicas, formações burocráticas estatais e reformas de governança pública. O objetivo foi analisar a repercussão desses temas em agendas e alternativas de políticas de governança pública e participativa no Brasil com ênfase nos conflitos entre governantes, políticos, funcionários, grupos de interesses e coalizões civis em disputa nos processos decisórios. O artigo assinala o caráter híbrido da democracia brasileira, em que o universalismo weberiano e a orientação às instituições de Estado de Bem-Estar que foram entrelaçados na matriz constitucional de 1988 operam em competição com duas outras lógicas – por um lado, a herança estamental da burocracia pública e, por outro, as iniciativas de governanças horizontais e participativas. As contradições dinâmicas entre esses quatro eixos definirão a competição pelo aparelho de Estado no contexto atual.

Published: February 2023

RESUMEN El desarrollo político-económico que ha tenido Chile durante las últimas décadas ha permitido la evolución de su institucionalidad sanitaria, donde se ha mejorado la cobertura, gestión e infraestructura hospitalaria. La organización de la política sanitaria es altamente centralizada y estructurada desde el Estado, ello ha permitido implementar con rapidez diversos programas. La participación, por otro lado, se mantiene dentro de los espacios que la institucionalidad permite, sin embargo, existe una permanente presión de grupos no gubernamentales que piden una gobernanza diferente. Se desea, por lo tanto, pasar de una reactividad participativa en materias sanitarias a una proactividad permanente, aunque ello requiere de una permanente conversación entre el Estado y la ciudadanía. En el artículo se analiza el sistema sanitario chileno y cómo se relaciona con la participación ciudadana subsecuente, evidenciando los elementos, que bajo la realidad social actual, necesitan de un cambio para satisfacer adecuadamente a la población.

RESUMO Com base no Curso de Qualificação de Avaliadores Externos para o processo de Acreditação no Sistema Único de Saúde (SUS), realizado em 2018, o objetivo deste artigo foi discutir os desafios postos ao processo de formação desses avaliadores, fundamentado em uma perspectiva da avaliação participativa, como forma de contribuir para aperfeiçoamento de processos dos dispositivos de avaliação externa e autoavaliação. Para isso, analisaram-se 33 documentos produzidos com a prática desses dispositivos no âmbito do projeto. Na avaliação externa, o principal desafio consiste em ‘olhar para o outro’; esse tipo específico de olhar exige que a Equipe de Avaliação Externa detenha o domínio sobre os conhecimentos prévios, competências e atitudes necessárias ao trabalho, para captar saberes, intencionalidades e relações, expressos nos atos de fala dos sujeitos. Na autoavaliação, o principal desafio consiste em ‘olhar para si’; tomar a si próprio como objeto de conhecimento e campo de transformação requer formas específicas de fazer, visando ao ganho de qualidade nos processos de trabalho. Construir uma cultura de avaliação, em que as informações produzidas subsidiem a tomada de decisão é um desafio para as ouvidorias, que pode ser superado com o Referencial de Qualidade das Ouvidorias do SUS.
