Risco de Desenvolvimento de Lesão em Decorrência de Posicionamento Cirúrgico: Estudo Observacional / Risk of Injury Development Due to Surgical Positioning: an Observational Study / Riesgo de Desarrollo de Lesiones Debido al Posicionamiento Quirúrgico: Estudio Observacional

Objetivo:Classificar o risco de desenvolvimento de lesão por posicionamento cirúrgico. Método: Estudo observacional, longitudinal, prospectivo, de abordagem quantitativa realizado em hospital público, com 135 pacientes submetidos à cirurgia eletiva. Utilizaram-se instrumentos contendo caracterização sociodemográfica, clínica e cirúrgica e escala de avaliação de risco para desenvolvimento de lesões decorrentes do posicionamento cirúrgico. Empregaram-se análise descritiva, teste exato de Fisher ou teste χ2 e a medida de associação odds ratio, conforme apropriado. Resultados: A maioria dos participantes era do sexo masculino (51,11%), adulta (52,59%) e foi classificada como maior risco para o desenvolvimento de lesões por posicionamento cirúrgico (51,85%). Ser idoso, hipertensão, diabetes mellitus e cirurgias urológicas foram estatisticamente significativos (p < 0,05) para maior risco de desenvolvimento de lesões. A incidência de lesão por pressão foi de 0,74%, com observação apenas na região sacra. Conclusão: Verificou-se maior risco para desenvolvimento de lesão em decorrência do posicionamento cirúrgico e baixa incidência de lesão por pressão. A enfermagem perioperatória deve incorporar à prática assistencial ferramentas validadas de mensuração de risco para um cuidado seguro, individualizado e de qualidade aos pacientes cirúrgicos.

Objective:To classify the risk of developing injury due to surgical positioning. Method: Observational, longitudinal, prospective study with a quantitative approach carried out in a public hospital, with 135 patients undergoing elective surgery. Instruments containing sociodemographic, clinical, and surgical characteristics and a risk assessment scale for the development of injuries due to surgical positioning were used. Descriptive analysis, Fisher's exact test or χ2 test and odds ratio association measure were used as appropriate. Results: Most participants were male (51.11%), adults (52.59%) and were classified as having a higher risk for developing injuries due to surgical positioning (51.85%). Elderly, hypertension, diabetes mellitus and urological surgeries were statistically significant (p < 0.05) for a higher risk of developing lesions. The incidence of pressure injuries was 0.74%, with observation only in the sacral region. Conclusion: There was a greater risk of developing lesions due to surgical positioning and low incidence of pressure injury. Perioperative nursing should incorporate validated risk measurement tools into care practice for safe, individualized and quality care for surgical patients,

Safety and Immunogenicity of an In Vivo Muscle Electroporation Delivery System for DNA-hsp65 Tuberculosis Vaccine in Cynomolgus Monkeys.

A Bacille Calmette-Guérin (BCG) is still the only licensed vaccine for the prevention of tuberculosis, providing limited protection against Mycobacterium tuberculosis infection in adulthood. New advances in the delivery of DNA vaccines by electroporation have been made in the past decade. We evaluated the safety and immunogenicity of the DNA-hsp65 vaccine administered by intramuscular electroporation (EP) in cynomolgus macaques. Animals received three doses of DNA-hsp65 at 30-day intervals. We demonstrated that intramuscular electroporated DNA-hsp65 vaccine immunization of cynomolgus macaques was safe, and there were no vaccine-related effects on hematological, renal, or hepatic profiles, compared to the pre-vaccination parameters. No tuberculin skin test conversion nor lung X-ray alteration was identified. Further, low and transient peripheral cellular immune response and cytokine expression were observed, primarily after the third dose of the DNA-hsp65 vaccine. Electroporated DNA-hsp65 vaccination is safe but provides limited enhancement of peripheral cellular immune responses. Preclinical vaccine trials with DNA-hsp65 delivered via EP may include a combination of plasmid cytokine adjuvant and/or protein prime-boost regimen, to help the induction of a stronger cellular immune response.

First Report of Colleters in Araceae: A Case Study in Anthurium andraeanum Reveals Diverse Mucilage Glands Associated with the Developing Shoot.

Araceae comprises a diverse group of plants that grow in various habitats, ranging from submerged aquatics to lithophytes. Thus, aroids are likely to show diverse glands acting in several plant-environment interactions, including colleters that protect young shoots. Based on this premise and the lack of studies regarding secretory structures in Araceae, we employed standard light and electron microscopy methods to test the hypothesis that colleters are present in Anthurium. Our main goals were to identify mucilage glands in A. andraeanum by conducting a detailed anatomical study of their structure, ultrastructure, and secretory activity. We found finger-like colleters in the apex of young leaves, spathes, and unexpanded cataphylls as well as secreting zones at the apex of expanded cataphylls, at the margins of non-fused cataphylls, and throughout the keels in two-keeled cataphylls. The colleters develop precociously and senesce shortly afterwards. Ultrastructural data and histochemistry confirmed the production of a polysaccharide-rich secretion that fills the spaces within the developing shoot. As far we know, this is the first time that colleters have been reported for Araceae. The functional roles of the secretion and the position of finger-like colleters concerning the 'precursor tip' of monocotyledons are discussed. Future research correlating secretory activity in colleters of species from different habitats might reveal a great diversity of mucilage glands with ecological and evolutionary significance to the family.

Complaints against Physicians in Minas Gerais, Brazil / Quejas contra médicos en Minas Gerais, Brasil / Reclamações contra médicos em Minas Gerais, Brasil

The Regional Councils of Medicine are responsible for the first instance evaluation of ethical-professional complaints against physicians in each federation state. The relevance of the study is based on the importance of evaluating the professional profile of the reported physician, the characteristics of the complaints, and the judging body performance. This study assessed 966 complaints against physicians made to the Regional Council of Medicine of Minas Gerais (CRM/MG) from 2012 to 2017. There was no difference in the average age of the professionals or the period of professional practice. Gynecology, Internal Medicine, General Surgery, and Plastic Surgery comprised most of the complaints regarding medical specialties. The non-specialty reports reached 323 (34%) cases and predominated over the years studied. The number of acquittals was relatively high, in a total of 535 cases, in which the Regional Council of Medicine of Minas Gerais (CRM/MG) considered the complaints unfounded. The hypothesis of a certain corporativism of the CRM did not seem viable since thirty cases received harsher punishments, and among them, eight were removed from professional practice. Some professionals were reported more than once. It is worth noting that the number of recidivists and cases progressively decreased from 2012 to 2017.

Los Consejos Regionales de Medicina son responsables de la evaluación en primera instancia de las denuncias ético-profesionales contra médicos en cada estado de la federación. La relevancia del estudio se basa en la importancia de evaluar el perfil profesional del médico denunciado, las características de las denuncias y la actuación del órgano juzgador. Este estudio evaluó 966 denuncias contra médicos presentadas al Consejo Regional de Medicina de Minas Gerais (CRM/MG) de 2012 a 2017. No hubo diferencias en la edad media de los profesionales ni en el período de ejercicio profesional. Ginecología, Medicina Interna, Cirugía General y Cirugía Plástica englobaron la mayoría de las denuncias relativas a especialidades médicas. Las denuncias de no especialidad alcanzaron 323 (34%) casos y predominaron a lo largo de los años estudiados. El número de absoluciones fue relativamente elevado, en un total de 535 casos, en los que el Consejo Regional de Medicina de Minas Gerais (CRM/MG) consideró infundadas las denuncias. La hipótesis de un cierto corporativismo del CRM no pareció viable, ya que treinta casos recibieron castigos más severos y, entre ellos, ocho fueron apartados del ejercicio profesional. Algunos profesionales fueron denunciados más de una vez. Cabe destacar que el número de reincidentes y de casos disminuyó progresivamente de 2012 a 2017.

Os Conselhos Regionais de Medicina são responsáveis pelas avaliações, em primeira instância, de denúncias ético-profissionais contra médicos, em cada estado da federação. A relevância do presente estudo se fundamenta na importância de se avaliar o perfil profissional do denunciado, as características das denúncias e o desempenho do órgão julgador. O presente estudo avaliou 966 denúncias contra médicos, feitas ao Conselho Regional de Medicina de Minas Gerais (CRM/MG), de 2012 a 2017. Não houve diferença com relação à média de idade do profissional, nem com relação ao tempo de exercício profissional. No que diz respeito às especialidades médicas (tabela 5), as áreas de Ginecologia, Clínica Médica, Cirurgia Geral e Cirurgia Plástica compreenderam grande parte das denúncias. Os denunciados sem especialidade alcançaram o no número de 323 (34%) e predominaram. O número de absolvições foi relativamente alto, num total de 535 denunciados, nos quais o Conselho Regional de Medicina de Minas Gerais (CRM/MG) considerou as acusações infundadas. A hipótese de certo corporativismo do CRM, não pareceu viável, visto que trinta casos receberam punição mais severa, dentre os quais, oito cassações do exercício profissional. Alguns profissionais foram denunciados mais de uma vez. Vale observar que o número de profissionais reincidentes, bem como o número de processos decaiu progressivamente, de 2012 a 2017.

Graphene as an inhomogeneously broadened two-level saturable absorber.

We show that the inter-band optical conductivity of graphene follows a dependence on intensity that is characteristic of inhomogeneously broadened saturable absorbers, and we obtain a simple formula for the saturation intensity. We compare our results with those from more exact numerical calculations and selected sets of experimental data, and obtain good agreement for photon energies much larger than twice the chemical potential.

Abstract: The study aimed to analyze the actions of the Professional Councils in relation to 966 professional-ethical complaints addressed to the Regional Council of Medicine of Minas Gerais between 2012 and 2017. The number of cases, gender, articles violated of the Code of Medical Ethics and decisions made in the lawsuits were considered. An expressive result was observed in terms of acquittal (535 cases) by the Regional Council of Medicine of Minas Gerais. There was a divergence when the same cases were evaluated by the Federal Council of Medicine, which upheld the acquittal in only 29% of the cases. Due to the methodology applied, it was not possible to go beyond speculation on the subject, being necessary a better analysis of the scientific community on this issue.

Are there still endogenous and reactive depressions? Clinical notes from a refractory Cotard Syndrome with a de novo post-ECT dissociative episode

Cotard syndrome is a mysterious and severe disorder. Many therapeutic interventions are reported as potentially efficacious mostly when an underlying psychotic depression or melancholia is diagnosed. However, the classification of depression has long been a contentious issue. Even though the major guide for therapeutic choice is severity, the binary model between endogenous and reactive depression is still widely employed in clinical practice. These considerations impact most clearly in in-between presentations. The authors present the case of R., a 64 year old woman, who was admitted with a major depressive episode with psychotic features, captured as a Cotard-like syndrome. After a two-months inpatient period and apparent clinical remission with high dose antidepressants and antipsychotic combination, she displayed an acute worsening leading to a re-admission just a day after discharge. The management in this second admission was tortuous, due to SARS-CoV2 related contingencies, the refractoriness of the presentation and iatrogenic intercurrences. The authors expose the course and treatment options employed, while reflecting on the question endogenous v. reactive, concluding that even seemingly clear clinical presentations may resist our different conceptualizations. (AU)

El síndrome de Cotard es un trastorno misterioso y grave. Muchas intervenciones terapéuticas son reportadas como potencialmente eficaces, perincipalmente cuando se diagnostica depresión psicótica o melancolía subyacentes. Sin embargo, la clasificación de la depresión ha sido una cuestión contenciosa durante mucho tiempo. Aun cuando la mayor guía para la elección terapéutica es la gravedad, el modelo binario entre depresión endógena y reactiva sigue siendo ampliamente utilizado en la práctica clínica. Estas consideraciones repercuten claramente en las presentaciones intermedias. Los autores presentan el caso de R., una mujer de 64 años, que fue ingresada con episodio depresivo mayor con características psicóticas, plasmado como síndrome de tipo Cotard. Tras dos meses de periodo hospitalario, y remisión clínica aparente con altas dosis de antidepresivos y combinación antipsicótica, mostró empeoramiento agudo conducente a reingreso transcurrido un solo día desde el alta. El manejo en este segundo ingreso fue tortuoso, debido a las contingencias relacionadas con el SARS-CoV2, la refractariedad de la presentación y las intercurrencias iatrogénicas. Los autores exponen el curso y las opciones de tratamiento utilizadas, a la vez que reflexionan sobre la cuestión endógena frente a reactiva, concluyendo que incluso las presentaciones clínicas aparentemente claras pueden resistirse a nuestras diferentes conceptualizaciones.

Objetivo:Verificar a adesão da equipe de enfermagem a um protocolo assistencial de fixação de cateter nasoenteral, após ação de educação em saúde. Método: Estudo quantitativo, transversal, de campo, observacional e descritivo, em um hospital no município do Rio de Janeiro. Constituiu-se de duas etapas: ação de educação em saúde sobre um protocolo de fixação de cateter nasoenteral e coleta de dados após ação de educação em saúde, sob a forma de observação não participante, com a utilização de instrumento contendo informações referentes à presença de fixação, tipo de fixação, registro da data do procedimento e condições da fixação do cateter nasoenteral. Resultados: As ações de educação em saúde abrangeram a participação de 133 profissionais de enfermagem. Dos 123 pacientes observados, 100% possuíam fixação, sendo a mais prevalente a fixação nasal (60,16% / n = 74). Em 68,29% (n = 84) não havia registro de data, 95,93% (n = 118) e 87,80% (n = 108) apresentavam boas condições de limpeza e aderência, respectivamente. Conclusão: Não se atingiu um resultado satisfatório quanto à adesão ao tipo de fixação e registro da data do procedimento. Apesar da adesão insatisfatória, houve alta correlação positiva entre a adesão dos profissionais nas ações de educação e razão de acerto do tipo de fixação

Objective:To verify the adherence of the nursing team to a care protocol for the fixation of a nasoenteral catheter, after a health education action. Methods: Quantitative, cross-sectional, field, observational and descriptive study in a hospital in the city of Rio de Janeiro. It consisted of two stages: health education action on a nasoenteral catheter fixation protocol and data collection after health education action, in the form of non-participant observation, using an instrument containing information regarding the presence of fixation, type of fixation, record of the date of the procedure and conditions of fixation of the nasoenteral catheter. Results: Health education actions encompassed the participation of 133 nursing professionals. Of the 123 patients observed, 100% had fixation, the most prevalent being nasal fixation (60.16% / n = 74). In 68.29% (n = 84) there was no date record, 95.93% (n = 118) and 87.80% (n = 108) had good cleaning and adherence conditions, respectively. Conclusion: A satisfactory result was not achieved regarding adherence to the type of fixation and registration of the date of the procedure. Despite the unsatisfactory adherence, there was a high positive correlation between the professionals' adherence to the education actions and the correctness ratio of the type of fixation.

Adult-onset non-5q proximal spinal muscular atrophy: a comprehensive review.

BACKGROUND: Adult-onset spinal muscular atrophy (SMA) represents an expanding group of inherited neurodegenerative disorders in clinical practice. OBJECTIVE: This review aims to synthesize the main clinical, genetic, radiological, biochemical, and neurophysiological aspects related to the classical and recently described forms of proximal SMA. METHODS: The authors performed a non-systematic critical review summarizing adult-onset proximal SMA presentations. RESULTS: Previously limited to cases of SMN1-related SMA type 4 (adult form), this group has now more than 15 different clinical conditions that have in common the symmetrical and progressive compromise of lower motor neurons starting in adulthood or elderly stage. New clinical and genetic subtypes of adult-onset proximal SMA have been recognized and are currently target of wide neuroradiological, pathological, and genetic studies. CONCLUSIONS: This new complex group of rare disorders typically present with lower motor neuron disease in association with other neurological or systemic signs of impairment, which are relatively specific and typical for each genetic subtype.

Resultados: Previamente restrito às apresentações de AME tipo 4 associada ao gene SMN1, este grupo atualmente envolve mais de 15 diferentes condições clínicas que compartilham entre si a presença de comprometimento progressivo e simétrico do neurônio motor inferior se iniciando no adulto ou no idoso. Novos subtipos clínicos e genéticos de AME proximal de início no adulto foram reconhecidas e são alvos atuais de estudos direcionados a aspectos neurorradiológicos, patológicos e genéticos. Conclusões: Este novo grupo complexo de doenças raras tipicamente se apresenta com doença do neurônio motor inferior em associação com outros sinais de comprometimento neurológico ou sistêmico, os quais apresentam padrões relativamente específicos para cada subtipo genético.

Acute hepatic porphyrias for the neurologist: current concepts and perspectives.

BACKGROUND: Acute hepatic porphyrias represent an expanding group of complex inherited metabolic disorders due to inborn errors of metabolism involving heme biosynthesis. OBJECTIVE: We aimed to review the main clinical and therapeutic aspects associated with acute hepatic porphyrias. METHODS: The authors provided a wide non-systematic review of current concepts and recently acquired knowledge about acute hepatic porphyrias. RESULTS: Acute neurovisceral attacks are the most common and life-threatening presentation of this group and are often considered the main clinical manifestation by clinicians during differential diagnosis and the start of proper diagnostic work-up for acute porphyrias. However, atypical presentations with central nervous system involvement, neuropsychiatric disturbances, and some subtypes with photosensitivity usually make the definite diagnosis difficult and late. Early therapeutic interventions are essential during emergency treatment and intercritical periods to avoid recurrent severe presentations. The availability of new disease-modifying therapeutic proposals based on small interfering RNA (siRNA)-based therapies, complementary to the classic intravenous glucose infusion and hemin-based treatments, emphasizes the importance of early diagnosis and genetic counseling of patients. CONCLUSIONS: This review article highlights the main biochemical, pathophysiological, clinical, and therapeutic aspects of acute hepatic porphyrias in clinical practice.

Intragenic variants in the SMN1 gene determine the clinical phenotype in 5q spinal muscular atrophy.

OBJECTIVE: The aim of the study was to report the proportion of homozygous and compound heterozygous variants in the survival motor neuron 1 (SMN1) gene in a large population of patients with spinal muscular atrophy (SMA) and to correlate the severity of the disease with the presence of specific intragenic variants in SMN1 and with the SMN2 copy number. METHODS: Four hundred fifty Brazilian patients with SMA were included in a retrospective study, and clinical data were analyzed compared with genetic data; the SMN2 copy number was obtained by multiplex ligation-dependent probe amplification and pathogenic variants in SMN1 by next-generation sequencing. RESULTS: Four hundred two patients (89.3%) presented homozygous exon 7-SMN1 deletion, and 48 (10.7%) were compound heterozygous for the common deletion in one allele and a point mutation in the other allele. Recurrent variants in exons 3 and 6 (c.460C>T, c.770_780dup and c.734_735insC) accounted for almost 80% of compound heterozygous patients. Another recurrent pathogenic variant was c.5C>G at exon 1. Patients with c.770_780dup and c.734_735insC had a clinical phenotype correlated with SMN2 copy number, whereas the variants c.460C>T and c.5C>G determined a milder phenotype independently of the SMN2 copies. CONCLUSIONS: Patients with specific pathogenic variants (c.460C>T and c.5C>G) presented a milder phenotype, and the SMN2 copy number did not correlate with disease severity in this group.

Curcuma Longa Abolishes Phenylephrine-Induced Contractions in Isolated Aortic Artery of Rats

Curcuma longa has biological effects. Its cardiovascular activities are yet to be scientifically studied. Objectives: To investigate the vasorelaxant effects of the aqueous extract of Curcuma longa (AECL). Methods: Aortic annuli of normotensive rats, with or without endothelium, were set up in a data storage system with nutrient solution in recipients, with scientifically recommended temperature, aeration and tension. Over contraction by Phenylephrine, the AECL (1, 3, 10, 30, 100, 300 and 1000 µg/mL) was incubated before and after incubation with atropine or L-name or indomethacin. An AECL concentration-response curve was also built over contractions caused by elevation of extracellular K+. Data were significant when p < 0.05, with GraphPad Prism 6.0 software resolutions. Results: The AECL induced 100% vasorelaxation also in the endothelium-free annuli. The part of the endothelium-dependent effect had EC50 = 4.32 ± 0.05 µg/mL. With inhibition of NO production, the EC50 increased to 126.50 ± 2.35 µg/mL; after inhibition of prostacyclin production, to 124.6 ± 0.05 µg/mL; and after muscarinic blockade, to 437.10 ± 0.2 µg/mL. Opening of K+ channels (relaxation of 56.98%) and VOCC blockade (relaxation of 31.56%) were evident. Conclusion: AECL induced significant vasorelaxation, being more significant in the presence of endothelium. The muscarinic pathway seems to be the main one involved in this effect, followed by the NO production and prostacyclin pathways. The activity in K+ channels by AECL was more significant than its VOCC blockade. The use of other models and tools to study action mechanisms will be important and elucidating

Novel Floral Scent Compounds from Night-Blooming Araceae Pollinated by Cyclocephaline Scarabs (Melolonthidae, Cyclocephalini).

Nocturnal flowering plants often release strong scents to attract their pollinators. Among night active flower visitors are cyclocephaline scarab beetles, which have been demonstrated to respond to uncommon volatile organic compounds released in high amounts by their host plants. In Araceae, the molecular structure of several such compounds is yet to be unveiled. We investigated headspace floral scent samples of Philodendron squamiferum, Thaumatophyllum mello-baretoanum, and Xanthosoma hylaeae by a variety of approaches, leading to the identification of novel compounds. Dehydrojasmone, (Z)-4-methylene-5-(pent-2-en-1-yl)cyclopent-2-en-1-one (1), (Z)-3-methylene-2-(pent-2-en-1-yl)cyclopentyl acetate (isojasmyl acetate, 3), and (E)-4,8-dimethylnona-1,3,7-trien-5-yl acetate (4) had not been previously reported, while full analytical data of the recently described (Z)-3-methylene-2-(pent-2-en-1-yl)cyclopentan-1-ol (isojasmol, 2) are presented here. All these compounds are derived from more common precursors, (Z)-jasmone and (E)-4,8-dimethyl-1,3,7-nonatriene, likely through biosynthetic "post-processing".

Correction to: Novel floral scent compounds from night-blooming Araceae pollinated by cyclocephaline scarabs (Melolonthidae, Cyclocephalini).

Condylar positioning in orthognathic surgery: a cone beam computed tomography-based in vitro analysis of a positioning method

Aim: Orthognathic surgery aims to correct facial skeletal deformities and the correct condylar positioning is very important for stable results. The aim of the present study was to verify the occurrence of changes in the postoperative condylar positioning in artificial skulls with a skeletal Class II maxillomandibular relationship submitted to bilateral sagittal split osteotomy when the method of cephalometric data transfer was used. Methods: Ten skeletal Angle class II polyurethane skulls were used with metallic markers in the articular surfaces of the temporomandibular joint and mandibular condyles. The skulls were submitted to preoperative and postoperative cone beam computed tomography before and after the bilateral sagittal split osteotomy. To verify the condylar positioning, measurements between the distances of the markers at the temporal bones and mandibular condyles were taken in the coronal and sagittal views by the DISTANCE tool of the iCat Vision software. All measurements were obtained by one examiner in the preoperative and postoperative CBCTs, tabulated and submitted to statistical analysis by the Wilcoxon test with a level of significance of 5% (p<0,05). After 15 days of the completion of the first data collection, all measurements were redone to determine the random and systematic error by the Intraclass Correlation Coefficient. Results: With the exception of the average of the lateral-medial distance (from the measurements between the medium left markers only), the averages of the anterior-posterior distances (only in the left posterior and lateral right markers) and the vertical average (only in the central markers) showed no statistically significant differences between the preoperative and postoperative distances of the metallic markers. Conclusion: Even when using the method of cephalometric data transfer, variation of the condylar positioning occurred between the preoperative and postoperative periods. This variation occurred only in a few points of the mandibular condyles

[Determinants of patents in the life sciences and health sciences at federal universities in Minas Gerais State, Brazil: an analysis of panel data for 1995-2016]. / Determinantes das patentes em ciências da vida e da saúde nas universidades federais de Minas Gerais, Brasil: uma análise de dados em painel para o período 1995-2016.

In the 1990s, the development of microelectronics and communication technologies spawned the information technology paradigm, characterized by an intensity of information which, transformed into knowledge and innovation, plays a crucial role for development. In order for this to occur, countries need to build appropriate institutional arrangements. This led to the Triple Helix model for systems innovation, which views innovation and technical progress in a Knowledge Economy as the result of a complex set of relations between universities, companies, and government. In this context, the current study aims to identify the impact of knowledge production and public policies for the production of patent applications by life sciences and health sciences researchers affiliated with federal universities in the State of Minas Gerais, Brazil. The analysis covered the years 1995 to 2016 and used econometric techniques in panel data. According to the findings, educational factors (thesis supervision), economic factors (technological products and the provision of technological services), and political factors (legal framework, financial resources, and incentive policies) impact the production of patent applications by the selected researchers. The results reveal efforts by government, although incipient, in the attempt to promote a technological leap.

Na década de 1990, com o desenvolvimento da microeletrônica e das tecnologias de comunicações, emergiu o paradigma da tecnologia da informação, caracterizado pela intensidade de informação que, transformada em conhecimento e inovação, desempenha um papel crucial para o desenvolvimento. Entretanto, para que isso ocorra, é necessário que os países construam arranjos institucionais apropriados. Com isso, surge o modelo de sistemas de inovação da Tríplice Hélice, que compreende a inovação e o progresso técnico, em uma Economia do Conhecimento, como o resultado de um conjunto complexo de relações entre universidade, empresa e governo. Nesse contexto, o presente estudo tem o objetivo de identificar o impacto da produção de conhecimento e das políticas públicas para a produção de depósitos de patentes dos pesquisadores pertencentes ao domínio científico Ciências da Vida e da Saúde, no âmbito das universidades federais de Minas Gerais, Brasil. A análise considerou o período de 1995 a 2016, e utilizou técnicas de econometria em painel de dados. Os resultados mostram que fatores educacionais (orientações em pós-graduação), econômicos (produtos tecnológicos e prestação de serviços tecnológicos) e políticos (arcabouço legal, recursos financeiros e políticas de estímulo) impactam a produção de depósitos de patentes dos pesquisadores selecionados. Por meio da análise dos resultados, podem-se perceber os esforços do governo, mesmo que ainda incipientes, na tentativa de promover o salto tecnológico.
