SUMMARY: Severe muscle injuries are common in accidents and have a delayed recovery of muscle integrity. In these cases, muscle suture surgery is the standard treatment. However, Platelet Rich Plasma (PRP), has been widely used in orthopedic injuries due to its growth factors. Thus, the objective of the study will be to analyze the association of suture and PRP techniques in the collagen and tenacity of the injured muscle. Were used seventy rats, divided into five groups: control (C), injury control (CI), injury and suture (IS), injury and PRP (IP), injury, suture, and PRP (ISP). Were sectioned approximately 50 % of the width and 100 % of the thickness of the gastrocnemius muscle. The homologous PRP was applied 24h after the injury. On the 7th day after the injury, the animals were euthanized and their muscles subjected to mechanical testing to measure tenacity or collagen analysis to calculate the ratio between type I and III collagen. The results show a significant decrease (p <0.05) in the values of the relationship between collagens in all injured groups (CI, IS, IP, ISP) compared to group C. In injured groups, the tenacity was significantly (p <0.05) reduced compared to the control group, with no observed difference between treatments and injured groups. The amount of collagen in the injured area has increased, but it did not affect the tenacity of the muscles, which was reduced.

RESUMEN: Las lesiones musculares graves son comunes durante los accidentes y la integridad del músculo está sujeta a una larga recuperación. En esos casos la cirugía, para la sutura del músculo, es el tratamiento común, no obstante el plasma rico en plaquetas (PRP) ha sido utilizado recientemente en lesiones ortopédicas, debido a sus factores del crecimiento. El objetivo del estudio fue analizar la asociación de las técnicas de sutura y PRP en la histología y tenacidad de músculo lesionado. Fueron utilizadas 70 ratas distribuidas en cinco grupos: control (C), control lesión (CL), lesión y sutura (LS), lesión y PRP (LPRP), lesión, sutura y PRP (LSPRP). Aproximadamente en la lesión, el 50 % de la longitud y el 100 % del espesor del músculo gastrocnemio fueron seccionados. El PRP homólogo fue aplicado 24 horas después de la lesión. En el 7º día después de la lesión los animales fueron eutanasiados y las muestras fueran sometidas al ensayo mecánico para la medición de la tenacidad y análisis del colágeno, para realizar el cálculo de la relación entre los colágenos I y III. Los resultados demostraron una reducción significativa (p<0,05) en los valores de la relación entre los colágenos en todos los grupos lesionados en relación al grupo C. La tenacidad fue (p<0,05) reducida significativamente en los grupos lesionados en relación al grupo control, sin diferencia entre los tratados. En la lesión muscular hubo disminución de los valores de colágeno, aunque en los tratamientos se observó elevación de la cantidad de colágeno en la área lesionada, esta no tuvo efecto en la tenacidad de los músculos que fue disminuida en la lesión.

Abstract While Primary Health Care (PHC) and Family and Community Medicine (FCM) have expanded their space and relevance in health care and undergraduate medical courses, Brazil has no stricto sensu FCM postgraduate programs. In this paper, we analyze some aspects of the Brazilian public health field and the national stricto sensu postgraduate system that can help to explain this scenario. As a contribution to the debate on this topic, we also gathered information from international postgraduate and research experiences in FCM and devised a curriculum proposal for future national FCM master’s courses. In the end, we discussed some key strategies for the emergence of stricto sensu postgraduate courses in this discipline in Brazil, highlighting the potential of these programs for evaluation and qualification of primary care services, especially the Family Health Strategy, and the training of PHC specialists required for the consolidation of the Unified Health System (SUS) as an accessible, comprehensive and equitable health system for the Brazilian population.

SUMMARY: The objective of this study was to evaluate the effects of growth hormone (GH) and muscle strength training (ST) on the composition of bone tissue of Wistar rats through Raman spectroscopy. In total, 40 male rats were randomly distributed into four groups: (N = 10) control (C), control with the application of GH (GHC), strength training (T), and strength training with the application of GH (GHT). The training consisted of four series of 10 water jumps, performed three times a week, with an overload corresponding to 50 % of body weight and duration of four weeks. GH was applied at a dose of 0.2 IU / kg in each animal three times a week and every other day. After four weeks, the animals were euthanized and the right femurs collected for analysis of the bone structure. Raman spectroscopy (ER) was used to observe the following compounds from their respective bands: Calcium Carbonate-Triglycerides (fatty acids) 1073 cm-1, Collagen type I 509 cm-1, Bone-DNA Phosphate (Protein) 589 cm-1, Phosphate Phospholipids 1078 cm-1. For the statistical analysis, the Shapiro-Wilk and ANOVA One-Way variance analysis normality tests were performed, followed by the Tukey post-test. The results showed an increase in the concentrations of calcium carbonate-triglycerides (fatty acids), type I collagen, bone phosphate-DNA (protein), and phosphate phospholipids in all experimental groups, with or without ST and/or GH , But only the isolated training group differed significantly from the control group (P <0.05). It was concluded that all treatments could promote bone tissue gain, however, only the T group demonstrated a significant difference in the mineral compounds analyzed.

RESUMEN: El objetivo del estudio fue avaluar el efecto de la aplicación de la hormona del crecimiento (GH) y entrenamiento de la fuerza muscular (EF) en la composición del tejido óseo de ratas Wistar a partir de la espectroscopía Raman. Fueron utilizadas 40 ratas machos distribuidas de forma aleatoria en cuatro grupos (n=10): control (C), control y aplicación de GH (GHC), entrenamiento de la fuerza muscular (EF) y entrenamiento de la fuerza muscular y aplicación del GH (GHE). El entrenamiento fue consistió en cuatro series de 10 saltos acuáticos, realizados tres veces en la semana, con sobrecarga correspondiente a 50 % de la masa corporal y durante cuatro semanas. El GH fue aplicado en la dosificación de 0,2 UI/kg en cada animal, tres veces en la semana y en días alternados. Después de cuatro semanas, los animales fueran eutanasiados y retirados los fémures derechos para un análisis de la estructura ósea. La espectroscopía Raman fue utilizada para observar los siguientes compuestos a partir de las respectivas bandas: Carbonato de Calcio-Triglicéridos (ácidos grasos) 1073 cm-1, Colágeno Tipo I 509 cm-1, Fosfato Óseo-DNA (Proteína) 589 cm1, Fosfato Fosfolípidos 1078 cm-1. Para el análisis estadístico, fueron realizadas las pruebas Shapiro-Wilk y el análisis de variancia ANOVA One-Way, seguida de test post hoc de Tukey. Los resultados revelaran aumento de la concentración de Carbonato de Calcio-Triglicéridos (ácidos grasos), Colágeno Tipo I, Fosfato Óseo- DNA (Proteína), Fosfato Fosfolípidos en todos los grupos experimentales, asociados o no a la realización del EF y/o aplicación del GH. Además, solamente el grupo EF mostró diferencia significativa del grupo C (p<0,05). Es posible concluir que todos los tratamientos mostraran aumentos en el tejido óseo, sin embargo, solamente el grupo T demostró una diferencia significativa en los compuestos minerales analizados.

RESUMO: Bemisia tabaci é conhecida no Brasil desde 1923, relatada em cultivos de algodão, soja, tomate e feijoeiro, promovendo prejuízos econômicos por ser transmissora de viroses. São praticamente inexistentes os trabalhos que analisam sua ocorrência em ambiente florestal. Nesse sentido, o objetivo deste trabalho foi estudar a ocorrência de B. tabaci em quatro fragmentos florestais de Mata Atlântica no estado do Rio de Janeiro, bem como registrar seus hospedeiros nesses ambientes. Em cada fragmento de Mata Atlântica foi demarcada uma área com cerca de um hectare, delimitada com o uso de imagens obtidas do Instituto Brasileiro de Geografia e Estatística (IBGE). Ao longo das inspeções mensais nos fragmentos florestais, os vegetais que apresentavam moscas-brancas foram marcados e inspecionados a toda nova visita. Adotaram-se critérios de coleta para garantir padronização do esforço amostral em todos os fragmentos. A análise do número médio de moscas-brancas foi feita pelo teste não paramétrico de Kruskal-Wallis, com posterior aplicação do pós-teste de Dunn, ambos a 5% de significância. Foram realizadas 216 coletas e capturadas 1.126 ninfas de quarto instar de B. tabaci nos quatro fragmentos de Mata Atlântica ao longo dos 24 meses. Registraram-se, pela primeira vez, os hospedeiros: Caesalpinia pluviosa Benth, Tradescantia zebrina Linn., Impatiens walleriana Linn., Cupania sp. e Talisia esculenta Klotzsch & O. Berg. O período seco (inverno) promove estímulos para o aumento da população de B. tabaci em fragmentos florestais.

ABSTRACT: Bemisia tabaci has been known in Brazil since 1923, in cotton, soybean, tomato and bean crops, and it leads to economic losses due to the transmission of different viruses. Studies focused on analyzing the incidence of this pest in forest environments remain scarce in the literature. Thus, the aims of the current study were to investigate the incidence of B. tabaci in four Atlantic forest fragments in Rio de Janeiro state, Brazil, as well as to record its hosts in these environments. An area of approximately one hectare was delimited for each Atlantic forest fragment based on images provided by the Brazilian Institute of Geography and Statistics (IBGE). Plants presenting whiteflies were tagged throughout monthly inspections conducted in each forest fragment in order to be checked during the following visits. Collection criteria were adopted to assure sampling standardization in each fragment. The mean number of whiteflies was analyzed through the Kruskal-Wallis non-parametric test, which was followed by Dunn’s post-hoc test, both at 5% significance level. The total of 216 collections were conducted and 1,126 B. tabaci fourth-instar nymphs were collected in four Atlantic forest fragments over 24 months. The following hosts were recorded for the first time: Caesalpinia pluviosa Benth, Tradescantia zebrina Linn., Impatiens walleriana Linn., Cupania sp. and Talisia esculenta Klotzsch & O. Berg. The dry period (winter) enabled the increase of B. tabaci populations in the herein investigated forest fragments.

RESUMO: São praticamente inexistentes os trabalhos que analisam a ocorrência de moscas-brancas em ambientes florestais, o que não é justificável, em vista da importância ecológica e agronômica desse grupo de insetos. Objetivou-se avaliar a ocorrência de Aleyrodidae em três fragmentos de Mata Atlântica no estado do Rio de Janeiro, no período entre maio/2013 e maio/2014. Propõe-se chave taxonômica para cinco gêneros. Coletaram-se 1.212 pupários e identificaram-se cinco gêneros e sete espécies de moscas-brancas ocorrendo em nove hospedeiros. Aleuropleurocelus cecropiae foi o único aleirodídeo registrado simultaneamente, ocorrendo em Cecropia hololeuca, nos três ambientes avaliados, com registros inferiores nos dois fragmentos considerados menos antropizados. Ainda, registrou-se pela primeira vez Aleurothrixus floccosus em Handroanthus ochraceus e em Mangifera indica. Também se procedeu ao primeiro registro de Bemisia tabaci em Commelina benghalensis e Caesalpinia pluviosa. Minutaleyrodes minuta sobre Syzygium cumini é, igualmente, o registro de uma nova ocorrência.

ABSTRACT: Studies that analyze the occurrence of whiteflies in forest environments are virtually non-existent, which is not justifiable given the ecological and agronomic importance of this insect group. The study aimed to evaluate the occurrence of Aleyrodidae collected from May/2013 to May/2014 in three Atlantic forest fragments in state of Rio de Janeiro, Brazil. Of all, 1,212 puparia were collected, and five genera and seven species of whiteflies occurring in nine hosts were identified. Aleuropleurocelus cecropiae was the only aleyrodid registered simultaneously occurring in Cecropia hololeuca in the three environments, with lower records in the two fragments considered as less anthropized. For the first time, Aleurothrixus floccosus was registered on Handroanthus ochraceus and Mangifera indica. In addition, it was observed the first register of Bemisia tabaci on Commelina benghalensis and Caesalpinia pluviosa. Minutaleyrodes minuta on Syzygium cumini was also the register of a new occurrence.

SUMMARY: The objective of this study was to investigate the alterations in morphology and aerobic resistance of rats subjected to different physical training protocols. The study consisted of 55 rats of the “Wistar” breed, 100 days of age, over a period of 8 weeks. The animals were randomly distributed between four groups: control (CTLE); neuromuscular anaerobic (TAN); aerobic (TAE) and concurrent training (TCc). After four weeks, some of the animals were euthanized. The body mass index (BMI), Lee index (Lee), epididymal adipose tissue (TecAdp), body weight, and feed efficiency ratio (CoefAlim) were measured. The Anaerobic Threshold was determined by critical workload (7 %, 9 % and 11 % of body weight). TAE and TCc training caused alterations in Lee and BMI, at four and eight weeks respectively (LeeTAE=X:2.86±0.08; X:2.89±0.07 and LeeTCc=X:2.85±0.05; X:3.00±0.09). For the TecAdp, all groups presented a decrease, with the TCc value down after eight weeks (X:1.77±0.32). Finally, TAN training improved the CoefAlim (X:31.57±3.70) after the eight week period and the TCc presented the highest value for Lan (X:7.10±0.80).

RESUMEN: El objetivo de este estudio fue investigar las alteraciones en la morfología y la resistencia aeróbica de animales sometidos a diferentes protocolos de entrenamiento. Se analizaron 55 ratas macho “Wistar” de 100 días de edad, durante un período de ocho semanas. Los animales fueron separados aleatoriamente en cuatro grupos: grupo control (CTLE); entrenamiento anaerobio neuromuscular (TAN); entrenamiento aerobio (TAE) y entrenamiento concurrente (TCc). Al término de cuatro semanas, algunos de los animales fueron sacrificados. Se midieron: índice de masa corporal (IMC), índice de Lee (Lee) y tejido adiposo del epidídimo (TecAdp), masa corporal y coeficiente de la eficacia alimentaria (CoefAlim). El umbral anaerobio (Lan) fue determinado por la carga crítica de trabajo (11, 9 y 7 % de la masa corporal). El entrenamiento TAE e TCc provocó alteraciones de Lee e IMC, en los períodos de cuatro y ocho semanas, respectivamente (LeeTAE=X:2,86±0,08; X:2,89±0,07 y LeeTCc=X:2,85±0,05; X:3,00±0,09). En relación a TecAdp, se observó una disminución en todos los grupos. Por último, el entrenamiento TAN mejoró en el período de ocho semanas para la variable CoefAlim (X:31,57±3,70) y el TCc con un valor mayor de Lan (X:7,10±0,80).

SUMMARY The objective of the present study was to analyze the effects of four different training models, two aerobic and two anaerobic models, in relation to muscular hypertrophy, by means of morphometric analysis of the muscle cells of the soleus muscle and the extensor digitorum longus muscle (EDL). The animals were divided into five groups, control (C), aerobic training in swimming (ATS), resistance training in water (RTW), aerobic training on a treadmill (ATT), and resistance training in climbing (RTC). The aerobic training was performed at 70 % of the anaerobic threshold for 30 minutes, while the RTW was composed of 3 series of 10 jumps, and the RTC 4 series of climbs, both at 80 % of the maximum load. All training protocols were performed for a total period of 4 weeks, 3 times per week. The diameters of the muscle cells were measured by means of histological slides of the EDL and soleus muscles. For the EDL muscle, there was no difference between the ATS and ATT aerobic training models (p = 0.20). However, the RTW presented greater hypertrophy when compared to the RTC (p <0.01). Regarding the soleus muscle, the ATS was responsible for generating greater hypertrophy than the ATT (p <0.01). In addition, the RTC was more efficient at producing hypertrophy than the RTW (p <0.01). In this way, it was concluded that exercise adaptation was according to exercise type, aerobic or anaerobic, and not to the modality used.

RESUMEN El objetivo del estudio fue analizar los efectos de cuatro diferentes modelos de entrenamiento, dos aeróbicos y dos anaeróbicos en la hipertrofia muscular en ratas, a través del análisis morfométrico de las células musculares de los músculos sóleo y extensor largo de los dedos (ELD). Los animales fueran divididos en cinco grupos: control (C), entrenamiento aeróbico en natación (TAN), entrenamiento resistido en medio acuático (TRA), entrenamiento resistido en escalada (TRE) y entrenamiento aeróbico en estera rodante (TRE). Los entrenamientos aeróbicos fueron realizados a 70 % del umbral anaeróbico, durante 30 minutos, en cuanto los TRA fueron realizados por 3 series de 10 saltos y el TRE, 4 series de escaladas, ambos a la intensidad de 80 % de la carga máxima. Todos los protocolos de entrenamientos fueron realizados tres veces a la semana por un período de 4 semanas. Fueron demarcados los diámetros de las células musculares de los músculos ELD y sóleo por medio de láminas histológicas. En el músculo ELD no se pudo observar diferencia entre los modelos de entrenamiento aeróbico TAN y TAE (p=0,20). Además, el TRA demostró mayor hipertrofia comparado al TRE (p<0,01). Con relación al músculo sóleo, el TAN fue responsable de generar mayor hipertrofia respecto al TRA (p<0,01). De este modo es posible concluir que la adaptación depende del tipo de ejercicio, aeróbico o anaeróbico, y no en función de la modalidad utilizada.

The aim of the present study was to observe the changes in the muscle tissue of rats after application of growth hormone (GH) and performing a strength training protocol (ST). In total, 40 male Wistar rats, 60 days old, were used, divided into four groups: control (C), control and application of GH (GHC), strength training (T), and strength training with the application of GH (GHT). The physical training protocol (PT) was composed of four series of 10 jumps in water, 3x/week, with an overload of 50 % of body weight for four weeks. GH was administered intraperitoneally at a dose of 0.2 IU/Kg to the GHC and GHT groups and saline (0.9 % sodium chloride) to the C and T groups. After four weeks of PT, the animals were euthanized and samples taken from the Soleus muscle. Histological sections were produced with a thickness of 5 mm and stained with hematoxylin-eosin (HE) and nicotinamide adenine dinucleotide tetrazolium reductase (NADH-TR). The markings for determining the measurement of the smallest diameter of muscle fibers (MF) were carried out using the software (AuxioVisionRel 4.8-Carl Zeiss® and NIS-Elements D3.0-SP7-Nikon®). After obtaining the data, the Shapiro-Wilk test for normality was performed and then the nonparametric Kruskal-Wallis with Dunn post-test were used for analysis of MF and the Student t test for the analysis of intragroup body weights. All procedures adopted a 5 % significance value (p <0.05) and were performed using the software SPSS 22.0 for Windows®. It was observed that both the GH and PT were able to generate increased diameter of MF (C:31.81±6.35; GHC:36.88±6.38; T:38.38± 6.94; GHT:36.89±7.16). Moreover, when analyzing the type, a significant increase was found only in the fast twitch MF (C:33.78±7.78; GHC:37.80±6.03; T:38.53±6.94; GHT:37.98±7.65) when compared to the slow twitch (C:25.93±6.66; GHC:26.95±8.03; T:26.24±6.90; GHT:27.20±5.77).

El objetivo de la investigación fue observar las modificaciones en tejido muscular esquelético de ratas después de la aplicación de la hormona del crecimiento (GH) y posterior entrenamiento de fuerza muscular (EFM). Fueran utilizadas 40 ratas Wistar, con 60 días de edad, distribuidas en: control (C), control y aplicación de la hormona del crecimiento (GHC), entrenamiento de fuerza muscular (T), y entrenamiento de fuerza muscular y hormona del crecimiento (GHT). El protocolo de entrenamiento (PT) fue compuesto por cuatro series de diez saltos acuáticos, 3x/semana, con sobrecarga de 50 % del peso corporal, por cuatro semanas. El GH fue aplicado de forma intraperitoneal con una dosis de 0,2UI/kg en grupos GHC y GHT y solución salina (0,9% clorhidrato de sodio) en grupos C y T. Después de cuatro semanas del PT, los animales fueron sacrificados y retirados los músculos sóleos. Se realizaron cortes de 5 µm los que fueron coloreados con Hematoxilina y Eosina (HE), posteriormente fueron sometidos a reacción con nicotinamida adenina dinucleotide tetrazolium reductasa (NADH-TR). Después de la obtención de los datos, fue utilizado la prueba del Shapiro-Wilk para la verificación de la normalidad de los datos y se usó el ensayo de Kruskal-Wallis con pos verificación del Dunn para análisis de las fibras musculares (FM) y prueba t del Student para la análisis del peso corporal entre los grupos. Todos los procedimientos fueron establecidos con valor de la significancia de 5 % (p<0,05) y realizados con el software SPSS 22.0 for Windows®. Fue verificado que tanto lo GH cuanto lo PT fueran capaces de proporcionar el aumento en el diámetro de las FM (C:31.81±6.35; GHC:36.88±6.38; T:38.38±6.94; GHT:36.89±7.16). En relación al tipo de fibras se observó aumento significativo solamente en las FM de contracción rápida (C:33.78±7.78; GHC:37.80±6.03; T:38.53±6.94; GHT:37.98±7.65) cuando se comparó con las FM de contracción lenta (C:25.93±6.66; GHC:26.95±8.03; T:26.24±6.90; GHT:27.20±5.77).

Abstract A sample of 39 rats were divided into the following groups: baseline (BL); aerobic training (ET4 and ET8); anaerobic training (ST4 and ST8); and concurrent training (CT4 and CT8). The aerobic training was performed by swimming with a load corresponding to 70% of the anaerobic threshold; the anaerobic training was performed by jumping in water with a load corresponding to 50% of body weight; and the concurrent training combined the two protocols. The analysis of BMDwas performed on the tibia of the animals and showed an increase in the density of the ST4, CT4, ET8, ST8, and CT8 groups when compared with both the BL and ET4. Thus, it is concluded that anaerobic exercise was shown to be effective in increasing the BMD of animals afterfour weeks of training; however, aerobic training was only able to raise BMD following eight weeks of training.

The aim of this study was to analyze changes in the skeletal muscle tissue of rats after muscle stretch injury using fractal analysis. Nineteen rats were divided into three groups, Control (n= 5) (C), Lesion two days (n= 7) (L2), and Lesion seven days (n= 7) (L7). Histological slides of the gastrocnemius muscle of the animals were prepared and stained with Hematoxylin and eosin for analysis of the inflammatory process, and picrosirius for the demonstration of collagen. The stained slides were subsequently analyzed using Fractal Dimension (FD). The results showed high FD values of the inflammatory process in the experimental groups L2 and L7 in relation to C (p= 0.000). The analysis of collagen in the picrosirius stained slides showed high FD in the L2 group compared to the L7 (p= 0.0001), with no statistically significant difference among other groups. In summary, the present study demonstrated that fractal analysis was able to identify changes in the inflammatory process in injured skeletal muscle tissue.

El objetivo de la investigación fue observar las modificaciones en tejido muscular esquelético en ratas después de la lesión por estiramiento muscular con análisis fractal. En el estudio se incluyeron 19 ratas, divididas en tres grupos, Control (n= 5) (C), lesión dos días (n= 7) (L2) y lesión siete días (L7). Los cortes histológicos del músculo gastrocnemio fueron coloreados con hematoxilina-eosina para el análisis de la inflamación y picrosirius para la determinación del colágeno. Los cortes histológicos fueron posteriormente analizados por medio de dimensión fractal (FD). Los resultados mostraron valores elevados de FD en proceso inflamatorio en los grupos experimentales L2 y L7, en comparación con grupo C (p= 0,000). El análisis de colágeno mostró mayor FD en grupo L2 comparado con L7 (p= 0,0001), se observó diferencia estadísticamente significativa con los demás. En resumen, esta investigación ha demostrado que el análisis fractal fue capaz de identificar las alteraciones del proceso inflamatorio en tejido muscular esquelético después de la lesión.

O presente documento traz diretrizes construídas conjuntamente pela Associação Brasileira de Educação Médica (ABEM) e a Sociedade Brasileira de Medicina de Família e Comunidade (SBMFC) com a intenção de apoiar as escolas médicas de forma objetiva e prática, na elaboração de projetos político-pedagógicos no contexto da Atenção Primária à Saúde. Um marco reconhecido na política educacional brasileira é a publicação das Diretrizes Curriculares Nacionais, as quais flexibilizam as organizações curriculares, possibilitando a construção de projetos político-pedagógicos contemporâneos e consonantes com o Sistema Único de Saúde brasileiro. A Atenção Primária à Saúde é o ponto de convergência entre estas duas políticas, descentralizando o ensino da Medicina dos hospitais para toda a rede de saúde no Brasil. Destaca-se a imperiosidade de que o ensino na Atenção Primária à Saúde esteja presente longitudinalmente, ao longo de todo o curso, de preferência com inserções significativas (de aprendizado real e a partir do trabalho), mas que, sobretudo, deva fazer parte do núcleo de ensino da prática clínica do futuro médico.

These are a set of guidelines built by the Brazilian Association of Medical Education (ABEM) and the Brazilian Society of Family and Community Medicine (SBMFC) with the aim of supporting medical schools in a practical and objective manner, when elaborating pedagogical-political projects on Primary Health Care (PHC). The advent of the Brazilian National Curricular Guidelines for Medical Education, which are approved by the Ministry of Education in 2001 have since improved the teaching of undergraduate medical students on PHC, but there are still wide variations in implementation and quality of it in medical curricula. These guidelines by ABEM/SBMFC partnership can exert considerable influence on medical curricula by establishing minimum requirements and core competencies for PHC in Brazil.
