An Educational international partnership responding to local needs: Process evaluation of the Brazil FAIMER Regional Institute

The Brazilian public health system requires competent professionals sensitive to the needs of the population. The Foundation for Advancement of International Medical Education and Research (FAIMER) provides a two-year faculty development programme for health professions educators, aiming to build leadership in education to improve health. A partnership with governmental initiatives and FAIMER was established for meeting these needs. This paper describes the initial process evaluation results of the Brazilian FAIMER Institute Fellowship (FAIMER BR). Methods: Data were analysed for the classes 2007-2010 regarding: application processes; innovation project themes; retrospective post-pre self-ratings of knowledge acquisition; and professional development portfolios. Results: Seventeen of 26 Brazilian states were represented among 98 Fellows, predominantly from public medical schools (75.5%) and schools awarded Ministry of Health grants to align education with public health services (89.8%). One-third (n = 32) of Fellows' innovation projects were related to these grants. Significant increases occurred in all topic subscales on self-report of knowledge acquisition (eff ect sizes, 1.21-2.77). In the follow up questionnaire, 63% of Fellows reported that their projects were incorporated into the curriculum or institutional policies. The majority reported that the programme deepened their knowledge (98%), provided new ideas about medical education (90%) and provided skills for conflict management (63%). One-half of the Fellows reported sustained benefits from the programme listserv and other communications, including breadth of expertise, establishment of research collaboration and receiving emotional support. Conclusion: Contributors to initial programme success included alignment of curriculum with governmental initiatives, curriculum design merging educational technology, leadership and management skills and central role of an innovation educational project responding to local needs.

On the Chaotic Suppression of Both Ideal and Non-ideal Duffing Based Vibrating Systems, Using a Magnetorheological Damper

In this paper the dynamics of the ideal and non-ideal Duffing oscillator with chaotic behavior is considered. In order to suppress the chaotic behavior and to control the system, a control signal is introduced in the system dynamics. The control strategy involves the application of two control signals, a nonlinear feedforward control to maintain the controlled system in a periodic orbit, obtained by the harmonic balance method, and a state feedback control, obtained by the state dependent Riccati equation, to bring the system trajectory into the desired periodic orbit. Additionally, the control strategy includes an active magnetorheological damper to actuate on the system. The control force of the damper is a function of the electric current applied in the coil of the damper, that is based on the force given by the controller and on the velocity of the damper piston displacement. Numerical simulations demonstrate the effectiveness of the control strategy in leading the system from any initial condition to a desired orbit, and considering the mathematical model of the damper (MR), it was possible to control the force of the shock absorber (MR), by controlling the applied electric current in the coils of the damper. © 2012 Foundation for Scientific Research and Technological Innovation.

High dosage folic acid supplementation, oral cleft recurrence and fetal growth

Objectives: To evaluate the effects of folic acid supplementation on isolated oral cleft recurrence and fetal growth. Patients and Methods: The study included 2,508 women who were at-risk for oral cleft recurrence and randomized into two folic acid supplementation groups: 0.4 and 4 mg per day before pregnancy and throughout the first trimester. The infant outcome data were based on 234 live births. In addition to oral cleft recurrence, several secondary outcomes were compared between the two folic acid groups. Cleft recurrence rates were also compared to historic recurrence rates. Results: The oral cleft recurrence rates were 2.9% and 2.5% in the 0.4 and 4 mg groups, respectively. The recurrence rates in the two folic acid groups both separately and combined were significantly different from the 6.3% historic recurrence rate post the folic acid fortification program for this population (p = 0.0009 when combining the two folic acid groups). The rate of cleft lip with palate recurrence was 2.9% in the 0.4 mg group and 0.8% in the 4 mg group. There were no elevated fetal growth complications in the 4 mg group compared to the 0.4 mg group. Conclusions: The study is the first double-blinded randomized clinical trial (RCT) to study the effect of high dosage folic acid supplementation on isolated oral cleft recurrence. The recurrence rates were similar between the two folic acid groups. However, the results are suggestive of a decrease in oral cleft recurrence compared to the historic recurrence rate. A RCT is still needed to identify the effect of folic acid on oral cleft recurrence given these suggestive results and the supportive results from previous interventional and observational studies, and the study offers suggestions for such future studies. The results also suggest that high dosage folic acid does not compromise fetal growth. © 2013 by the authors; licensee MDPI, Basel, Switzerland.

High incidence of 'Dag-like' sperm defect in the domestic cat

The occurrence of a high incidence of sperm tail defects in a male domestic cat resembling the known 'Dag-like' defect is reported. Sperm analyses were performed in ejaculated samples collected by an artificial vagina and in testicular and epididymal sperm cells after castration. The following alterations were observed using transmission electron microscope: heavily coiled sperm tails containing several axonemal units enclosed in the same common cell membrane; aberrations in the axonemal main structure; and swollen and unevenly distributed mitochondria in the midpiece. Abnormal modifications in the mitochondrial sheath were also found in sperm cells retrieved from testes and epididymides. Considering these findings, we can conclude that this is the Dag-like defect, described previously in other domestic species and a testicular origin may be involved. © ISFM and AAFP 2012.

Deproteinized bovine bone mineral particles and osseointegration of implants without primary bone contact: An experimental study in dogs

Objectives: To evaluate the influence on osseointegration of Deproteinized bovine bone mineral (DBBM) particles used to fill defects of at least 1 mm around implants having no primary contact with bone. Material and methods: Premolars and first molars were extracted bilaterally from the mandible of six Labrador dogs. After 3 months of healing, mucoperiosteal full-thickness flaps were elevated, and one recipient site was prepared in the molar region of each hemi-mandible to place implants. These were installed with a deliberate circumferential and periapical space to the bone walls of 1.2 mm. All implants were stabilized with passive fixation plates to maintain the implants in situ and without any contact with the implant bed. The control sites were left to be filled with coagulum, while at the test sites, the residual gap was filled with DBBM. After 3 months of submerged healing, the animals were sacrificed. Ground sections were prepared and analyzed histomorphometrically. Results: Mineralized bone-to-implant contact was 4.0% and 3.9% for control and test sites, respectively. The width of the residual defects was 0.48 mm and 0.88 mm at the control and test sites, respectively. The percentage of implant surface covered by a layer of dense connective tissue of 0.12 mm of width on average was 84.9% and 88.5% at the control and test sites, respectively. Conclusion: A minor and not predictable degree of contact or distance osteogenesis was obtained on the implant surface when primary contact of the implant surface with the implant bed had deliberately been avoided. DBBM grafting of the artificial gap did not favor osseointegration. Neither did it enhance the ability to bridge the gap with newly formed bone in an artificial defect wider than 1 mm. © 2013 John Wiley & Sons A/S.

Avaliação de polimorfismos de genes metabolizadores de xenobióticos em pacientes com fissura labiopalatina atendidos no Estado do Pará

Fissura lábio palatina ou orofaciais é um dos mais frequentes defeitos congênitos existentes e vários estudos relacionam essa malformação a causas multifatoriais. Entre as diversas causas ambientais estão os hábitos etílicos e tabagistas maternos, assim como o uso de agrotóxico. A resposta do embrião humano a agentes teratogênicos é bem conhecida. Porém, sabe-se que organismos diferentes metabolizam de maneira distinta um mesmo componente químico, isto se deve a características genéticas intrínsecas relacionadas a diferentes funcionamentos enzimáticos. Tais diferenças podem ser investigadas a partir da análise de polimorfismos em genes relacionados ao metabolismo destes xenobióticos, que podem assim estar relacionados à etiogênese de fissuras lábio palatinas. O Objetivo do nosso estudo foi analisar polimorfismos em sete genes, PON1 (rs662), PON1 (rs854560), MTHFD1, CYP2E1, EPHX1, ABCB1, AHR, onde uma análise correlativa com fatores ambientais, como exposição a agrotóxicos foi realizada, a fim de avaliar se existe ou não influência das diferentes variantes polimórficas e tais interações ambientais na etiogênese das fissuras lábio palatinas. O número total de amostras analisadas foi de 166 indivíduos, sendo 83 pacientes acometidos por fissura, com idade média de 7 anos (DP 5 anos) e 83 mães dos mesmos. Em nossas amostras, o gênero masculino foi 64% do total de acometidos.; uma ficha para a coleta de dados epidemiológicos foi desenvolvida para o estudo; o material biológico coletado para análise foi sangue. A análise estatística foi realizada com os softwares bioEstat 5.3, SPSS 12.0 e PLINK 1.07. Nosso resultado consiste de quatro análises diferentes, para cada polimorfismo. Inicialmente, observamos as diferenças entre as frequências genotípicas encontradas nos acometidos e nas mães destes e aquelas das populações de indivíduos hígidos. Isto visando encontrar diferenças entre estes genótipos que possam justificar a gênese das FLP, frente à exposição das mães, e intrauterinamente, dos filhos ao agrotóxico. Num segundo momento, verificamos se houveram diferenças entre os genótipos maternos e dos acometidos, que pudessem representar diferenças significativas entre estes dois grupos de indivíduos (pois as mães, independentemente da exposição ao agrotóxico, poderiam ter FLP, caso o genótipo fosse de elevada importância) e que possam ter relação com a FLP. Em uma terceira análise, observamos se os genótipos encontrados nos indivíduos que apresentam FLP, estão relacionados à exposição relatada aos agrotóxicos, como fator etiológico destas más formações. Em ultima análise, visamos, por análise de regressão, verificar se a característica genotípica desses alvos de estudo, possa ter influenciado no fenótipo do tipo de fissura, seja somente labial, seja palatal ou labiopalatal. A distribuição dos tipos de fissuras entre os acometidos foi de 12% para fissuras somente labiais, 19% para fissuras somente palatais e 69% das fissuras em nosso grupo amostral atingiam o lábio e o palato.

Genotype effect on carcass and meat quality of lambs finished in irrigated pastures in the semiarid Northeastern Brazil

The aim of this study was to compare four genetic groups of sheep on the carcass and meat quality traits. Thirty-three contemporary and unrelated male lambs, all of single birth were used in the experiment, being thirteen from the Santa Inês (SI) breed, seven from the Brazilian Somali breed (BS), six from the Morada Nova (MN) breed and seven from the ½ Dorper - ½ Morada Nova (F1) crossbreed. The genotypes SI, BS and F1 presented similar performances in relation to hot and cold carcass weights, which values were 10.76±0.53kg and 10.46±0.52kg for SI, 9.20±0.73kg and 8.99±0.71kg for BS, and 9.35±0.73kg and 9.13±0.71kg for F1, respectively. The BS had a better hot carcass yield (47.10±0.88%) and cold carcass yield (46.00±0.87%). Better carcass conformation was observed in SI and F1 (2.73±0.12 and 2.50±0.17, respectively) while the BS presented a better finishing (3.29±0.20). The average for the rib eye area (REA) was 9.94±0.49cm², 8.66±0.67cm², 7.18±0.72cm² and 9.8±0.67cm², and for the carcass compactness index (CCI) it was 0.17±0.01kg/cm, 0.17±0.01kg/cm, 0.11±0.01kg/cm and 0.16±0,01kg/cm, for SI, SB, MN and F1, respectively. There were no significant differences between SI, BS and F1 regarding REA and CCI. Although, in general, the MN presented a relatively lower performance than the other genotypes, this breed had similar carcass yields and fat thickness when compared to SI and F1 and similar conformation and REA in comparison to the BS. Regarding meat quality, no differences were observed between genotypes, except for redness and cooking losses. It is concluded that no one group had a higher or lower performance in all traits analyzed. Moreover, for the management conditions employed in this study, there was evidence of greater specialization in meat production for genotypes SI, BS and F1 when compared to MN, although there are no substantial differences between the four groups regarding meat quality.

The Primary Closure Approach of Dog Bite Injuries of the Nose

The nose holds an outstanding position on the face, acquiring great importance within the context of facial aesthetics. Because of the functional, psychological, and social aspects of trauma in a society increasingly demanding about aesthetics, treatment institution must reduce, as accurate as possible, the sequelae that hinder social integration. This clinical report relates an immediate nasal reconstruction of a complex animal bite wound. A 7-year-old patient was victim of a dog bite with avulsion of the left nasal ala and part of the ipsilateral nasal tip. The treatment was immediate nasal reconstruction with auricular composite graft. After 1 year of follow-up, the shape of nasal ala was stable, and the color was consistent with the surrounding tissue. The 2 nasal sides exhibited satisfactory symmetry when evaluated. It can be concluded that the composite graft derived from the auricular helix is a safe option for reconstruction of nasal ala defects with compromised margins in pediatric patients when conditions of reimplantation do not exist.
