eLearning for health in Brazil - UNA-SUS in numbers.
Use of technology enabled learning for distance education in the health field is growing, and new challenges are emerging related to reaching health professionals working in remote areas. The Open University of the Unified Health System (UNA-SUS) promotes Continuing Professional Development and uses Technology Enhanced Learning (TEL) for distance education to theBrazilian health workforce, mainly in primary care. Methods: As part of ongoing quality assurance assessments, we performed a descriptive analysis of courses, learners, and completion rates from all enrolments in UNA-SUS for Qualification and Specialisation Courses. Data were collected directly from the UNA-SUS information system. Results: From March 2008 to October 2015 (91 months), UNA-SUS had 206,834 enrolments in 40 Specialisation Courses and 60 Qualification Courses, reaching 119,109 professionals (mean - 1.7 courses per person). These were distributed amongst 5,199 Brazilian municipalities, 59% of which had a population of 10,000 to 50,000 inhabitants. Learners were mainly women (80.6%), nurses (26.4%), and working in primary care (39.8%). Completion rates were 67.3% for Specialisation Courses and 37.9% for Qualification Courses, which were self-instructional. Reaching 93% of all Brazilian cities and 119,109 learners, UNA-SUS was able to deliver health education to health professionals (physicians, nurses, and others) in rural and other areas of shortage such as indigenous districts and metropolitan outskirts. UNA-SUS has succeeded in expanding ten-fold the seats for Specialisation Courses for family health, and has good results in TEL Qualification Courses. UNA-SUS has innovated Continuing Professional Development for health professionals in Brazil. These courses responded to the previously unattended educational needs of the workforce,
focusing on reaching primary care professionals in
smaller towns and remote areas. UNA-SUS is consolidating itself as a nationwide provider of continuing education

OBJETIVO: o presente estudo avaliou, por meio de uma an?lise retrospectiva, a estabilidade p?s-tratamento do alinhamento dos incisivos anterossuperiores de pacientes submetidos ao tratamento ortod?ntico sem extra??es. M?TODOS: a amostra foi constitu?da de 23 pacientes (13 do sexo feminino e 10 do sexo masculino), com idade inicial de 13,36 ? 1,81 anos. Mediu-se nos modelos de estudo das fases inicial (T1), final (T2) e p?s-tratamento (T3) de aproximadamente de 5 anos, a irregularidade dos incisivos superiores, as dist?ncias intercaninos e entre os primeiros e segundos pr?-molares, a dist?ncia intermolares, o comprimento e o per?metro da arcada superior. Ap?s a obten??o dos dados, realizou-se a an?lise estat?stica. Para a an?lise das altera??es ao longo dos tr?s tempos estudados, utilizou-se a an?lise de vari?ncia (ANOVA) a um crit?rio de sele??o e, em caso de resultado significativo, o teste de Tukey. Para verificar a presen?a de correla??o entre a recidiva do apinhamento anterossuperior e a recidiva das vari?veis dist?ncias intercaninos, interpr?-molares, intermolares, comprimento e per?metro da arcada, utilizou-se o teste de correla??o de Pearson. RESULTADOS: os resultados n?o evidenciaram altera??es dimensionais significativas ao final do tratamento; entretanto, durante o per?odo de p?s-tratamento, foram observadas altera??es significativas em rela??o ? quantidade de irregularidade dos incisivos superiores. CONCLUS?O: concluiu-se que houve recidiva estatisticamente significativa (+1,52mm) na irregularidade anterossuperior durante o per?odo de p?s-tratamento. Entretanto, nenhuma das vari?veis aferidas nos modelos p?de ser clinicamente associada ? recidiva anterossuperior.Funda??o de Amparo ?

METHODS: The sample comprised 23 patients (13 female; 10 male) at a mean initial age of 13.36 years (SD = 1.81 years), treated with fixed appliances. Dental cast measurements were obtained at three different time points (T1 - pretreatment, T2 - posttreatment and T3 - long-term posttreatment). Variables assessed in maxillary arch were Little Irregularity Index, intercanine, interpremolar and intermolar widths, arch length and perimeter. The statistical analysis was performed by one-way ANOVA and Tukey tests when necessary. Pearson' correlation coefficients were used to investigate possible associations between the evaluated variables. RESULTS: There was no significant change in most arch dimension measurements during and after treatment, however, during the long-term posttreatment period, it was observed a significant maxillary incisors crowding relapse. CONCLUSION: The maxillary incisors irregularity increased significantly (1.52 mm) during long-term posttreatment. None of the studied clinical factors demonstrated to be predictive of the maxillary crowding relapse

Objetivo: descrever a constru??o de estrat?gias educacionais e o perfil dos egressos dos dois primeiros cursos autoinstrucionais do Programa de Qualifica??o em Sa?de da Pessoa Idosa (PQSPI). M?todo: an?lise descritiva do perfil de egressos do PQSPI, a partir de banco de dados consolidado da Universidade Aberta do SUS (UNA-SUS), em cursos desenhados sob constru??o reversa. Cursos conceberam-se sob dois formatos diferentes, desenvolvidos por tr?s equipes distintas, com a parceria e homologa??o da Coordena??o de Sa?de da Pessoa Idosa do Minist?rio da Sa?de. Resultados: foram desenvolvidos dois cursos, distribu?dos em sete ofertas, entre 2016 e 2018, voltados para: profissionais de n?vel superior, especialmente m?dicos/enfermeiros, curso 1; e t?cnicos/auxiliares de enfermagem (TAE) e agentes comunit?rios de sa?de (ACS), curso 2. O p?blico mais comum em todos os cursos foi de estudantes (37,9%). Dentre os profissionais, os TAE superaram m?dicos e os ACS foram o 4? p?blico mais frequente no curso 1; no curso 2, os TAE e os ACS foram os mais frequentes, com taxas de conclus?o em torno de 50%. Conclus?o: demonstrou-se maior interesse de estudantes, TAE e ACS nos cursos autoinstrucionais, sendo necess?rio estudar melhor sua participa??o. Os TAE e ACS t?m menos oportunidade de capacita??o, sendo um p?blico estrat?gico para a??es futuras.Aims: to describe the construction strategy and the learners? profile of the two initial selfinstructional courses on the Health of the Elderly Qualification Program (PQSPI). Method: descriptive analysis of the PQSPI learner?s profile from the Open University of SUS (UNASUS) consolidated database. The courses were designed based on reverse construction, when the learning objectives are the first to be drawn, followed by the activities, and then, the theoretical content is developed from it. The reverse construction involved 5 different formats, 3 production teams, and was approved by the Coordination of the Elderly from the Ministry of Health. Results: two courses with 7 educational offers were developed, directed to: graduated professionals, mainly physicians and nurses, course 1; Nursing technicians/assistants (NTA) and community health agents (CHA), course 2. The most common public for all courses was mainly composed by graduation students, demonstrating undergraduate?s interest in permanent education courses. NTA outperformed physicians and CHA were the fourth most common professional audience in course 1. In course 2, NTA and CHA were the most common audience and had completion rates around 50%. Conclusion: greater interest from students, NTA, and CHA in self-instructional courses was demonstrated, so it?s necessary to study in depth their participation. NTA and CHA have less opportunity for competencies building, being a strategic audience for future actions
Proposal of Home Care Residency as actuation field.
A Aten??o Domiciliar (AD) configura-se numa ?rea de atua??o de diversos especialistas, como
M?dicos de Fam?lia e Comunidade, Geriatras, Pediatras e Internistas. Por suas especificidades
e dentro do seu campo de pr?ticas, demanda compet?ncias que n?o est?o contempladas
isoladamente em nenhuma especialidade m?dica, sendo que o tempo e a estrutura necess?rios
para a aquisi??o destas ultrapassa a capacidade de inser??o ao longo dos programas atuais.
A expans?o desta modalidade de cuidados representa uma demanda crescente de forma??o,
exigindo a inclus?o da AD como potencial campo de trabalho destes especialistas, concebendo
a necessidade de um ano adicional para forma??o nas especificidades dessa ?rea de atua??o.
Discutem-se as estrat?gias de forma??o, campos da pr?tica e estrutura program?tica necess?rios
para a consolida??o desta proposta. Espera-se que este artigo possa subsidiar a natural constru??o
desta especialidade no ?mbito da atua??o m?dica em sa?de.Home Care (HC) is an expertise area for several specialists, such as Family Physicians, Geriatricians,
Pediatricians and Internal Medicine. Due to its specificities and within its practice field, it demands
competences that are not contemplated apart in any medical specialty, and the time and structure
required to acquire them surpasses the insertion capacity in the current programs. This care type
expansion represents a growing demand for training, requiring HC inclusion as a potential field of work
for these specialists, conceiving the need for an additional year for the formation of specific features
as an activity area. We discuss training strategies, practice fields and programmatic structure required
to consolidate this proposal. We expect that this article can subsidize the natural construction of this
specialty within the scope of health medical practice
Electro-optical interfacial effects on a graphene/?-conjugated organic semiconductor hybrid system.
The influence of graphene and retinoic acid (RA) ? a ?-conjugated organic semiconductor ? interface on their hybrid system is investigated.
The physical properties of the interface are assessed via scanning probe microscopy, optical spectroscopy (photoluminescence
and Raman) and ab initio calculations. The graphene/RA interaction induces the formation of a well-organized ?-conjugated
self-assembled monolayer (SAM) at the interface. Such structural organization leads to the high optical emission efficiency of
the RA SAM, even at room temperature. Additionally, photo-assisted electrical force microscopy, photo-assisted scanning Kelvin
probe microscopy and Raman spectroscopy indicate a RA-induced graphene doping and photo-charge generation. Finally, the
optical excitation of the RA monolayer generates surface potential changes on the hybrid system. In summary, interface-induced
organized structures atop 2D materials may have an important impact on both design and operation of ?-conjugated nanomaterialbased
hybrid systems
Raman evidence for pressure-induced formation of diamondene.
Despite the advanced stage of diamond thin-film technology, with applications ranging
from superconductivity to biosensing, the realization of a stable and atomically thick
two-dimensional diamond material, named here as diamondene, is still forthcoming. Adding
to the outstanding properties of its bulk and thin-film counterparts, diamondene is predicted
to be a ferromagnetic semiconductor with spin polarized bands. Here, we provide spectroscopic
evidence for the formation of diamondene by performing Raman spectroscopy of
double-layer graphene under high pressure. The results are explained in terms of a breakdown
in the Kohn anomaly associated with the finite size of the remaining graphene sites
surrounded by the diamondene matrix. Ab initio calculations and molecular dynamics
simulations are employed to clarify the mechanism of diamondene formation, which requires
two or more layers of graphene subjected to high pressures in the presence of specific
chemical groups such as hydroxyl groups or hydrogens
