ABSTRACT The big jumps are steps that require muscular power and motor coordination. Since there is a lack in the literature on the learning and training of these steps, the aim of this study was to verify the effect of 12 weeks of classical ballet classes with the grand allegro exercise on lower limb power in amateur ballerinas. Seven dancers, aged 11.33±1.02 years, who were studying Grade 3 of Royal Academy of Dance, participated Height Growth Speed Peak calculations, vertical jump tests, and technical evaluation of the grand allegro exercise were performed at four moments over the 12-week study period. Lesson plans, the Rating of Perceived Exertion, and the Total Recovery Quality for each class were collected to analyze load and recovery. The main results indicate that the dancers were prepubertal and lower limb muscular power and the technique of the grand allegro exercise improved (p<0.05). Weekly load and the quantity of jumps and exercises performed varied during the period, while Total Recovery Quality remained stable. The obtained data point to variations in the workload during ballet classes, combined with the sensitive phase of development and motor coordination, as responsible for the improvement in muscular power and technical quality. coordination 1 ballerinas 1133102 11 33 02 11.33±1.0 years Dance calculations tests 12week week period plans Exertion recovery p<0.05. p005 p p<0.05 . 0 05 (p<0.05) stable quality 113310 11.33±1. p00 p<0.0 (p<0.05 11331 11.33±1 p0 p<0.

RESUMO Os grandes saltos são passos que exigem potência muscular e coordenação motora. Visto que há uma escassez na literatura sobre o aprendizado e treinamento destes passos, o objetivo deste estudo foi verificar o efeito de doze semanas de aulas de ballet clássico com o exercício de grand allegro sobre a potência de membros inferiores em bailarinas amadoras. Participaram sete bailarinas, com 11,33±1,02 anos de idade, que cursavam o Grade 3 da Royal Academy of Dance. Foram realizados cálculos de Pico de Velocidade de Crescimento, testes de salto vertical e avaliação técnica do grand allegro em quatro momentos durante doze semanas. Os planos de aula, Percepção Subjetiva de Esforço e Qualidade Total de Recuperação de cada aula foram analisadas. Os principais resultados apontam bailarinas pré-púberes, cuja potência muscular e técnica do exercício de grand allegro apresentaram melhora (p<0,05). A carga semanal e quantidade de saltos e de exercícios executados variaram durante o período, enquanto que a Qualidade Total de Recuperação se mostrou estável. Os dados obtidos apontam para as variações da carga de trabalho nas aulas de ballet somadas à fase sensível do desenvolvimento e coordenação motora como os responsáveis pela evolução na potência muscular e na qualidade técnica. amadoras 1133102 11 33 1 02 11,33±1,0 idade Dance Crescimento analisadas prépúberes, prépúberes pré púberes, púberes pré-púberes p<0,05. p005 p p<0,05 . 0 05 (p<0,05) período estável 113310 11,33±1, p00 p<0,0 (p<0,05 11331 11,33±1 p0 p<0, (p<0,0 1133 11,33± p<0 (p<0, 113 11,33 p< (p<0 11,3 (p< 11, (p

ABSTRACT Purpose: To evaluate visual outcomes, satisfaction, and quality of life of patients assisted in a Medical School hospital by the Brazilian Public Health System, who underwent bilateral diffractive multifocal intraocular lens implantation. Methods: Case series study with intervention, including 20 patients who underwent bilateral implantation of multifocal IOL EyeDiff® (Eyeol UK, Dunstable, UK). Exclusion criteria were corneal astigmatism >1.5 cylindrical diopters, previous ocular surgery or ocular disease, and intra- or postoperative complications. Patients were evaluated one, three, and six months after surgery. Monocular and binocular visual acuity for distance, intermediate and near, under photopic and mesopic conditions, monocular contrast sensitivity under photopic conditions, defocus curve, and quality of life were assessed. Results: Monocular distance-corrected visual acuity was 0.3 logMAR or better and monocular distance-corrected near visual acuity was J3 or better in all eyes under photopic conditions. Binocular distance-corrected near visual acuity was J1 in all cases. Contrast sensitivity was at the minimum level of normality for low and high spatial frequencies and within normal limits for intermediate spatial frequency. The quality of life questionnaire showed a high level of patient satisfaction. Conclusion: Bilateral implantation of the multifocal intraocular lens EyeDiff® provides patients with good visual acuity and quality of life, besides spectacle independence. The visual acuity and contrast sensitivity progressively improved between one and six postoperative months.

Abstract Background: Children and adolescents should be encouraged to participate in sports; however, physicians should screen for cardiac abnormalities that can lead to sudden death. The European Society of Cardiology, the Brazilian Society of Cardiology and the Brazilian Society of Sports Medicine indicate performing an electrocardiogram (ECG) in evaluating athletes, while the American Heart Association indicates complementary exams only when there is a personal or family history of cardiovascular diseases or changes in clinical examination. Objectives: To evaluate the need for an ECG in evaluating children and adolescents before starting physical activities. Methods: We recruited 983 children and adolescents who practiced physical activities for anthropometric assessment, clinical examination and conventional ECG at rest. Variables were analysed using the Goodman test with a significance level of 5%. Results: Participants had a higher incidence of overweight, obesity and severe obesity compared to standard World Health Organization (WHO) values. The most common finding in clinical examination was heart murmur (18.5% of participants). Electrocardiographic changes were found in 3.3% of participants, including paroxysmal supraventricular tachycardia and pre-excitation syndrome, which may be responsible for sudden death, even in asymptomatic individuals with no personal or family history of heart disease and no abnormality on clinical examination. Conclusions: ECG revealed arrhythmias that were not detected by clinical examination and may precede sudden death in individuals subjected to physical exertion, indicating its role in the assessment of children and adolescents before starting regular physical exercise.

ABSTRACT Petri disease is a problem for vineyard caused mainly by the fungus Phaeomoniella chlamydospora. Contaminated seedlings are source of inoculum for the disease. Treatment to disinfect vine rootstock cuttings for seedling production is hot water treatment (HWT) by 50 °C for 30 min, but the efficiency is contested. To improve its efficacy, the study aimed to assess the combination of the following methods and the reason for the control: i) exposition of the fungus to five different temperatures in HWT bath for 30 min; ii and iii) exposition of the fungus and also plants infected with P. chlamydospora to different disinfection treatments (biofumigation = soil + cabbage at 40 °C; temperatures of 40 and 23 °C, all in microcosm), in different periods (7, 14 and 21 days), with and without additional HWT (51 °C for 30 min). The results showed that HWT with high temperatures (55–70 °C) for 30 min inactivated the fungus. Biofumigation technique at 40 °C and the temperature solely of 40 °C applied for up to 21 days and combined with HWT (51 °C for 30 min) inhibited mycelial growth and inactivated the fungus in vine plant tissues without compromising the rooting.

RESUMO Objetivo: Avaliar as razões para não comparecimento à clínica oftalmológica da universidade após triagem oftalmológica realizada usando uma unidade móvel oftalmológica que fornece exame oftalmológico para comunidades não assistidas em uma região do Brasil. Métodos: Foi realizado um estudo observacional prospectivo no ano de 2017/2018 para avaliar as razões que fizeram com que os indivíduos triados usando uma unidade móvel oftalmológica e referenciados para a clínica oftalmológica da universidade não comparecessem à consulta agendada. A triagem foi feita em 10 municípios da região centro-oeste do estado de São Paulo, Brasil. Todos os 1.928 participantes fizeram o exame oftalmológico sem custo e 37,1% deles necessitaram de encaminhamento para a clínica oftalmológica da universidade para exames especializados ou cirurgias. O estudo usou duas ferramentas: (1) análise comparativa entre os dados dos indivíduos encaminhados que compareceram ao agendamento com os que não compareceram; (2) busca ativa dos indivíduos que não compareceram à consulta agendada, aplicando-se um questionário para avaliar os motivos para o não comparecimento. Resultados: Fatores como idade, sexo, distância entre a cidade de origem e o hospital universitário, número de oftalmologistas na cidade de procedência, renda familiar média e acuidade visual não influenciaram no comparecimento ao encaminhamento. Catarata foi a maior causa para o encaminhamento (350 casos). O não comparecimento foi maior nos portadores de glaucoma/glaucoma suspeitos (54,1%), estrabismo (45%) e afecções do segmento anterior (33,6%). Muitos indivíduos que não compareceram ao serviço de referência procuraram por outro local para o atendimento oftalmológico. Conclusão: O não comparecimento para tratamento oftalmológico sem custo depende de fatores relacionados ao paciente ou à falta de conhecimento das próprias condições oftalmológicas. Campanhas educativas nas comunidades assistidas devem ser feitas para alcançar maior comparecimento às consultas e melhor prevenir a cegueira evitável.

ABSTRACT Purpose: This study aimed to identify patient’s reason for no-show at a university eye clinic after ophthalmic examination via a mobile ophthalmic unit, which provides comprehensive ophthalmic care to underserved communities in a region of Brazil. Methods: In 2017/2018, this prospective observational study searched for no-shows at referrals to a university eye clinic after an outreach program screening via a mobile ophthalmic unit in 10 municipalities in the central-western region of São Paulo, Brazil. A total of 1,928 patients underwent a comprehensive eye examination at no cost, and 37.1% of them needed referral to a university eye clinic for specialized examinations or surgeries. We used the following two main tools: (1) comparative analysis between patients who attended the referral and those who did not; (2) active search using a questionnaire to assess reasons for no-show. Results: Attendance to referrals was not influenced by age, gender, distance from the university hospital, number of ophthalmologists in the municipality, average family income, and visual acuity. The main cause for referrals was cataract (350 cases). No-show was most common among glaucoma/suspected glaucoma (54.1%) cases, followed by strabismus (45%) and anterior segment disease (33.6%) cases. Many patients who did not attend the referral sought another service. Conclusion: Patient’s issues and lack of knowledge regarding their ophthalmic condition are the main reasons for no-show at referrals for free ophthalmic care. Thus, educational campaigns are needed to achieve consistently high attendance to prevent avoidable blindness.

Abstract Background: As some individuals present resistance to obesity development, experiments have been trying to understand their susceptibility to cardiometabolic diseases. Objetive: To evaluate if the cardiac remodeling was related to collagen protein expression change. Methods: Male Wistar rats were randomized into two experimental groups: control diet (CD, n=15) or high-fat diet (HFD, n=15) for 30 weeks. Rats fed with HFD were ranked based on their adiposity indexes and classified as obese (Ob, n = 8) or obesity-resistant (ROb, n = 6). Rats that failed to present the normal characteristic of the control group while fed with CD were excluded (Control, n = 8). Nutritional profile, comorbidities (dyslipidemia, hypertension, glucose metabolism, hyperleptinemia), cardiac remodeling, and collagen protein expression were evaluated. The groups were compared by One-Way ANOVA, together the Tukey post hoc test, with p<0.05 considered significant. Results: The Ob rats presented an increased adiposity index when compared to C and ROb. Both groups Ob and ROb presented increased low-density lipoprotein (LDL), insulin, homeostatic model assessment of insulin resistance (HOMA- IR) and systolic blood pressure (SBP), and low high-density lipoprotein (HDL) levels when compared to the control group. The levels of triglycerides, non-esterified fatty acid (NEFA), and leptin were lower in ROb as compared to Ob, but higher than the control group. The Ob and ROb groups presented cardiac remodeling, evidenced by echocardiographic and post-mortem analysis. The collagen protein expression did not differ among the groups. Conclusion: The ROb animals present cardiac remodeling that is not related to collagen type I and III protein expression change.

SUMMARY OBJECTIVE: First care providers working in the Brazilian Unified Health System are often physicians from the Family Health Program. Their knowledge on ophthalmology could indicate whether there is a need for training to decrease ophthalmological demands to secondary or tertiary health levels. METHODS: A cross-sectional observational study based on an electronic questionnaire was conducted to evaluate the ophthalmological knowledge of Family Health Program physicians working at the VI Regional Health Department, Sao Paulo, Brazil. All Family Health Program physicians from this regional health department were invited, and the study included those who responded to the full questionnaire (115 physicians). The data were evaluated using descriptive analysis. RESULTS: There was no difference in the ophthalmological knowledge between sexes or in relation to undergraduate schools. Only 20% of the interviewees were specialized in Family and Community Medicine, which did not influence the number of correct answers. Only 22 (19.1%) physicians reported having enough knowledge about the main eye disorders, and 82 (71.3%) physicians considered themselves capable of treating ophthalmological emergencies. However, acute glaucoma was recognized by only 51 (44.3%) physicians, and eye perforations could only be handled by 65 (56.5%) of them. In addition, only 47 (40.9%) participants correctly answered that congenital cataracts should be operated right after diagnosis. CONCLUSIONS: Family Health Program physicians working as first care providers in the Health System in Brazil presented poor ophthalmological knowledge. Providing training on ophthalmology may improve the ophthalmological care at the primary level within SUS and reduce the case demands at other healthcare levels.

ABSTRACT Introduction Infrared thermography has been used in several areas, mainly in sports training, and specifically in soccer. Objectives The objectives of the study were to verify the acute effect of a displacement speed test on the skin temperature of elite female soccer players, to observe pre- and post-test thermal asymmetries, and to compare responses in the anterior and posterior regions of lower limbs. Methods Cross-sectional study that evaluated 17 soccer players of the 2018 Brazilian Championship. They were submitted to thermography before and 10 minutes after performing the displacement speed test. Thermographic images were collected using a FLIR® model 8 thermal imager and changes in skin temperature in the anterior and posterior regions of the lower limbs were analyzed, according to the areas of interest. Descriptive statistics were performed and mean and standard deviation of the temperatures of the areas of interest were analyzed. The normality of the data was verified, and then the Student’s t test for normal paired and independent samples and the Mann-Whitney test for non-normal samples were conducted, with p <0.05 being adopted for significance level. Results It was possible to observe that after the test there was an increase in skin temperature in all the regions analyzed, both on the dominant and non-dominant sides (p <0.05). Regarding the analysis of the anterior region, it was possible to observe a higher temperature (p <0.05) in the region of the tibial muscles than in the region of the quadriceps muscles. Conclusion It is concluded that thermography helps to understand the thermal responses of lower limbs after applying the displacement speed test. The study shows that thermographic evaluation can guide the organization of the training session when motor tests have previously been applied, and in the detection of abnormal overloads, helping to prevent injuries.

RESUMO Objetivo: Determinar o impacto do uso de unidade móvel no acesso à saúde ocular e avaliar o perfil da população que necessita de cuidados oftalmológicos, as doenças oculares mais frequentes e o tratamento. Métodos: Estudo transversal realizado em 14 municípios da região sudoeste do Estado de São Paulo utilizando uma unidade móvel oftalmológica. Os participantes eram usuários do Sistema Único de Saúde que procuraram atendimento oftalmológico, sem restrição quanto a idade, gênero ou condição socioeconômica. Os dados foram transferidos para a tabela Excel para análise estatística. Resultados: Participaram do estudo 6.878 pessoas, com média de idade de 44 anos (variação de 4 meses a 96 anos) e 65,5% eram mulheres. Erros refrativos estavam presentes em 78,6% dos participantes, catarata em 9,6% e pterígio em 8,3%. Para 60% foram prescritos óculos, para 10% foi mantida a correção óptica em uso e para 28% foram necessárias apenas orientações. Exames especializados ou procedimentos cirúrgicos foram indicados para 18,1% dos casos que foram encaminhados para tratamento em serviço terciário. Dentre os pacientes referenciados, 36,4% necessitavam de cirurgia oculoplástica ou para tratar afecções externas do olho e 31,8%, de cirurgia de catarata. Conclusão: A grande maioria dos pacientes que procurou atendimento na unidade móvel necessitava de prescrição de óculos. A unidade móvel oftalmológica possui alto grau de resolutividade para os problemas oculares, com oportunidade de tratar os erros refrativos e referenciar os pacientes que necessitam de atendimento especializado, geralmente relacionado a condições cirúrgicas. Unidades móveis podem ser uma alternativa aos cuidados oftalmológicos básicos, melhorando o acesso, atuando na promoção da saúde ocular e prevenindo a cegueira.

ABSTRACT Purpose: The goal of this study was to determine the impact of a mobile eye health unit on access to eye care and to generate a profile of the population requiring ophthalmic care by age, nature of their ophthalmic diseases, and optimal management. Methods: The study was conducted in 14 cities in the southwest region of São Paulo, Brazil. Subjects included individuals who participate in the Brazilian Unified Health System who were in need of eye care. There were no restrictions on age, gender or socioeconomic status. Data was transferred to an Excel table for statistical analyses. Results: We evaluated 6,878 participants in this survey with mean age of 44 years (range 4 months to 96 years); 65.5% were female. Among the diagnoses, 78.6% presented with refractive errors, 9.6% presented with cataracts and 8.3% presented with pterygium. New corrective lenses were prescribed for 60.9% of the participants; 10% retained their existing lenses, ~28% required counseling only and18.1% of the participants were referred to a tertiary facility for specialized exams and/or surgical procedures. Of the participants who required outside referrals, 36.4% required oculoplastic/external eye surgery and 31.8% required cataract surgery. Conclusion: The vast majority of patients presenting to a mobile eye health unit required prescriptions for corrective lenses. The rate of detection of ocular disorders was relatively high and the mobile unit provided effective treatment of refractive errors and referrals for specialized ophthalmic examinations and procedures. A mobile eye health unit can be an effective alternative method for improving access to basic eye care, for promoting eye health education and preventing blindness.

ABSTRACT Trachoma is a keratoconjunctivitis caused by Chlamydia trachomatis, considered an important leading cause of preventable blindness in the world. This study aimed at verifying if flies can be the vectors for trachoma in our municipality. Flies were assessed in the households of children diagnosed with inflammatory trachoma at the municipality of Botucatu, Sao Paulo State, Brazil. Fly traps were placed in the backyard of the houses during 24 h, in each of the four weather seasons, over a period of one year. The collected dipterans were taxonomically classified and the presence of Chlamydia trachomatis in the flies was evidenced by using the Polymerase Chain Reaction (PCR). During the studied period, 2,188 flies were collected, mainly during the summer and the spring. The most common identified fly was Musca domestica. All fly samples were negative for Chlamydia trachomatis but several other different bacteria were identified in these flies. The authors concluded that flies are probably not the vectors for trachoma in the studied area. Further studies should be conducted to evaluate other possible factors responsible for the maintenance of the disease in our environment.

ABSTRACT Objective: To evaluate whether there is a relationship between diet quality and bone health in a group of elderly Brazilian women. Subjects and methods: A cross-sectional study was performed with 105 elderly women. Participants were evaluated regarding diet quality (good, needing improvement, and poor) and its relationship with bone mineral density (BMD), bone-specific alkaline phosphatase (BSAP), and C-telopeptide (CTX). Results: Fifty eight participants (55.2%) presented a poor-quality diet and 47 (44.8%) required dietary improvements, while no subjects presented a good quality diet. The group requiring dietary improvements had lower CTX [0.35 (0.05;1.09) vs. 0.52 (0.10;1.45); p = 0.03)] and BSAP (38.7 ± 12.9 U/L vs. 46.10 ± 15.2 U/L; p < 0.01) levels than the poor-quality diet group. Groups did not differ in terms of BMD. Conclusion: In this group of elderly Brazilian women, there was a relationship between diet quality and bone health, where worse diet quality was associated with higher levels of bone remodelling markers.

Resumo Fundamento A obesidade é um fator de risco para complicações médicas, incluindo o sistema cardiovascular. Há informações limitadas sobre o colágeno no coração obeso. Nosso estudo anterior demonstrou uma redução dos níveis proteicos de colágeno miocárdico tipo I em ratos obesos alimentados com uma dieta com alto teor de gordura durante 34 semanas. No entanto, os mecanismos responsáveis pelos níveis baixos não estão completamente elucidados. Objetivo O objetivo deste estudo foi testar a hipótese de que a redução do colágeno tipo I está associada ao aumento da atividade da metaloproteinase-2 (MMP-2), a qual está ligada à elevação de leptina no miocárdio de ratos obesos. Métodos Ratos Wistar machos com 30 dias de idade foram randomizados em dois grupos: controle (dieta padrão) e obeso (dieta com alto teor de gordura), e alimentados durante 34 semanas. Foram avaliados as características gerais dos animais e os perfis metabólicos e endócrinos. Foram avaliados as expressões proteicas miocárdicas de colágeno tipo I, leptina e inibidores teciduais de metaloproteinases (TIMP), bem como a atividade da MMP-2. O teste de correlação de Pearson foi aplicado para determinar as associações entre variáveis. O nível de significância foi de 5%. Resultados Os animais obesos apresentaram índice de adiposidade mais elevado em comparação ao controle. Foram observadas comorbidades como intolerância à glicose, hiperinsulinemia, resistência à insulina, hiperleptinemia e hipertensão nos ratos obesos. A obesidade reduziu o colágeno tipo I, TIMP-1 e TIMP-2, e aumentou a leptina e a MMP-2 no miocárdio. Houve uma correlação negativa entre o colágeno tipo I e a MMP-2 e uma correlação positiva entre a leptina e a MMP-2. Conclusão Foi confirmada a hipótese de que a redução do colágeno tipo I está associada ao aumento da atividade da MMP-2 e da expressão de leptina no miocárdio de ratos obesos.

Abstract Background Obesity is a risk factor for medical complications, including the cardiovascular system. There is limited information on collagen in the heart in obesity. Our previous study showed decreased protein levels of myocardial collagen type I in obese rats fed a high-fat diet for 34 weeks. However, the mechanisms responsible for low levels are not fully elucidated. Objective The purpose of this study was to test the hypothesis that the reduction in collagen type I is associated with increased metalloproteinase-2 (MMP-2) activity, which is linked to elevated leptin in the myocardium of obese rats. Methods Thirty-day-old male Wistar rats were randomized into two groups, control (standard diet) and obese (high-fat diet), and fed for 34 weeks. The general animal characteristics and metabolic and endocrine profiles were evaluated. Myocardial protein expressions of collagen I, leptin, tissue inhibitors of metalloproteinases (TIMP), and MMP-2 activity were assessed. Pearson correlation was employed to determine the associations between variables. The level of significance was 5%. Results The obese animals had increased adiposity index compared to control. Comorbidities such as glucose intolerance, hyperinsulinemia, insulin resistance, hyperleptinemia, and hypertension were observed in obese rats. Obesity reduced collagen I, TIMP-1, and TIMP-2, and it increased leptin and MMP-2 in the myocardium. There was a negative correlation between collagen I and MMP-2 and a positive correlation between leptin and MMP-2. Conclusion The hypothesis was confirmed; the reduction in collagen type I is associated with increased MMP-2 activity and leptin expression in the myocardium of obese rats.
