Success attitudes of young ophthalmologists in the first decade of their career

PURPOSE: To describe the main success attitudes of young ophthalmologists in the first decade of their career. METHODS: This descriptive study comprised subjects selected from a sample of ophthalmologists who were participating in a congress, using a semi-structured questionnaire. The inclusion criteria were as follows: ophthalmologists under the age of 40 years, within 5-10 years from ophthalmology residency conclusion. The subjects were asked about the three main success attitudes in their personal experience during the first years of ophthalmology practice. After the initial results, the 10 most frequently mentioned attitudes were listed and volunteers were again interviewed to choose, within the latter list, the three main attitudes. RESULTS: Forty-eight ophthalmologists were interviewed, 24 (50%) were male; the mean age was 37 years (SD: 2 years, range: 33-40 years) and the mean time from ophthalmology residency conclusion was 8 years (SD: 1 year, range: 5-10 years). The frequency of such mentioned success attitudes were as follows: to invest in professional updating (22.9%), to have a good relationship with patients and professional partners (18.8%), to prioritize individual and family happiness (12.5%), initially to work in an established group (11.1%), to work in public service (9.7%), to have their own business with a homogeneous group (7.6%), to save money (7.6%), to be ready to resume work (4.2%), to get business administration skills (4.2%), and to have professional insurance (0.7%). CONCLUSIONS: The three main success attitudes consisted in investing in professional updating (22.9%), maintaining a good relationship with patients and professional partners (18.8%), and prioritizing individual and family happiness (12.5%). Although these results should not be generalized, they are helpful not only for those ophthalmologists at the beginning of a career but also those who want to reflect on what to prioritize in their professional practice.

Effects of detachment and repositioning of the medial pterygoid muscle on the growth of the maxilla and mandible of young rats

PURPOSE: To analyze the effects of detachment and repositioning of the medial pterygoid muscle on the growth of the maxilla and mandible of young rats through cephalometry. METHODS: Thirty one-month-old Wistar rats were used, distributed into three groups: experimental, sham-operated and control. In the experimental group, unilateral detachment and repositioning of the medial pterygoid muscle was performed. The sham-operated group only underwent surgical access, and the control group did not undergo any procedure. The animals were sacrificed at the age of three months. Their soft tissues were removed and the mandible was disarticulated. Radiographs of the skull in axial projection and the hemimandibles in lateral projection were obtained, and cephalometry was performed. The values obtained were subjected to statistical analyses among the groups and between the sides in each group. RESULTS: There were significant differences in the length of the mandible relative to the angular process in the experimental group and in the height of the mandibular body in the sham-operated group. CONCLUSION: The experimental detachment and repositioning of the medial pterygoid muscle during the growth period in rats affected the growth of the angle region, resulting in asymmetry of the mandible.

Effects of the unilateral removal and dissection of the masseter muscle on the facial growth of young rats

This study analyzed the effects of the unilateral removal and dissection of the masseter muscle on the facial growth of young rats. A total of 30 one-month-old Wistar rats were used. Unilateral complete removal of the masseter muscle was performed in the removal group, and detachment followed by repositioning of the masseter muscle was performed in the dissection group, while only surgical access was performed in the sham-operated group. The animals were sacrificed at three months of age. Axial radiographic projections of the skulls and lateral projections of the hemimandibles were taken. Cephalometric evaluations were made and the values obtained were submitted to statistical analyses. In the removal group, there were contour alterations of the angular process, and a significant homolateral difference in the length of the maxilla and a significant bilateral difference in the height of the mandibular body and the length of the mandible were observed. Comparison among groups revealed significance only in the removal group. It was concluded that the experimental removal of the masseter muscle during the growing period in rats induced atrophic changes in the angular process, as well as asymmetry of the maxilla and shortening of the whole mandible.

Risk indicators for aggressive periodontitis in an untreated isolated young population from Brazil

This study aimed to assess the prevalence of aggressive periodontitis (AgP), and to investigate the association between demographic, socioeconomic and behavioral risk indicators with AgP in an untreated and isolated young population in Southeastern Brazil. For this cross-sectional survey, 134 subjects aged 12-29 years were selected by a census. Of those eligible, 101 subjects received a full-mouth clinical examination, and were interviewed using a structured written questionnaire. Cases were defined as individuals with 4 or more teeth with attachment loss > 4 mm or > 5 mm in the age groups 12-19 and 20-29, respectively. Overall, 9.9% of the subjects presented AgP (10.3% of the 12-19-year-olds and 9.7% of the 20-29-year-olds). The only risk indicator significantly associated with AgP in this isolated population was a high proportion of sites (> 30%) presenting supragingival calculus [OR = 23.2]. Having experienced an urgency dental treatment was a protective factor for AgP [OR = 0.1]. The authors concluded that this isolated and untreated population from Brazil presented a high prevalence of AgP. Local plaque-retaining factors played a major role in the prevalence of AgP in this isolated population, and should be included in further studies evaluating this destructive periodontal disease form.

Fatores associados ao consumo de frutas e hortaliças no Brasil, 2006

OBJETIVO: Estimar a freqüência do consumo de frutas e hortaliças e fatores associados. MÉTODOS: Foram estudados 54.369 indivíduos com idade >18 anos, entrevistados pelo sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (VIGITEL) nas capitais brasileiras e Distrito Federal, em 2006. Os indicadores do consumo alimentar foram: consumo regular (>5 dias/semana) de frutas e hortaliças e consumo adequado (>5 vezes/dia). Calculou-se a prevalência dos indicadores e intervalos de confiança, estratificada por sexo. Para analisar a associação das variáveis sociodemográficas foram calculados odds ratio bruta e ajustada por sexo, idade, escolaridade e estado civil. RESULTADOS: Menos da metade dos indivíduos referiu consumo regular de fruta (44,1%) ou hortaliças (43,8%), enquanto 23,9% referiram consumo regular de frutas e hortaliças em conjunto; o consumo adequado foi referido por 7,3% dos entrevistados. O consumo de frutas e hortaliças variou entre as cidades estudadas, foi maior entre as mulheres e aumentou com a idade e escolaridade. CONCLUSÕES: Iniciativas de promoção do consumo de frutas e hortaliças devem atender a população como um todo, especialmente às cidades das regiões Norte e Nordeste, aos jovens, aos homens e aos estratos populacionais com baixa escolaridade.

Comportamento de risco para transtorno alimentar em universitárias brasileiras

CONTEXTO: Comportamentos de risco para transtornos alimentares envolvem atitudes e práticas inadequadas para com o alimento e o peso e podem ser avaliados com base em instrumentos validados. OBJETIVOS: Avaliar comportamento de risco para transtornos alimentares em universitárias brasileiras das cinco regiões do país. MÉTODOS: 2.483 universitárias responderam ao Teste de Atitudes Alimentares (EAT-26) nas cinco regiões. A pontuação no teste foi comparada entre as regiões por meio do teste qui-quadrado. Possíveis associações ou correlações com curso de graduação, idade, estado nutricional, renda individual e escolaridade do chefe da família foram avaliadas pelos coeficientes de Pearson e Spearman. Uma análise de covariância comparou o escore do EAT entre as regiões. RESULTADOS: A frequência de comportamento de risco para transtornos alimentares variou de 23,7% a 30,1% nas cinco regiões e não houve diferença na pontuação média do EAT e na proporção de escores positivos para comportamento de risco entre as regiões. Não houve forte correlação do escore do EAT com nenhuma das variáveis. CONCLUSÃO: Universitárias brasileiras apresentam alta frequência de comportamentos de risco para TA em todas as regiões do país. Medidas de prevenção devem ser planejadas para a população jovem feminina do Brasil.

O risco de incidência e persistência da obesidade entre adultos Brasileiros segundo seu estado nutricional ao final da adolescência

INTRODUÇÃO: A prevalência da obesidade vem aumentando entre adultos nos países desenvolvidos e em desenvolvimento. No Brasil, a obesidade entre adultos atingiu entre 2008 a 2009 pelo menos 10% da população. OBJETIVOS: Com base nos dados do VIGITEL, neste trabalho, serão estimadas a incidência e a persistência da obesidade entre brasileiros adultos no período de 2006 a 2009. MÉTODOS: Nas amostras de 2006 a 2009, foram utilizados casos com registros demográficos, socioeconômicos e antropométricos completos. As estimativas foram expandidas para a população brasileira em 2007. A estimativa do risco relativo (RR) para incidência e persistência da obesidade ou excesso de peso entre homens e mulheres foi feita com regressão múltipla de Poisson, e ajustada para hábito de fumar, idade e atividade física. RESULTADOS: A incidência do excesso de peso entre indivíduos com peso baixo ou normal, aos 20 anos, é estimada em 40%, no sexo masculino, e em 30%, no feminino. A persistência da obesidade, por sua vez, é estimada em 65%, no sexo masculino, e em 47%, no feminino. O gradiente da obesidade como função da escolarização é virtualmente nulo no sexo masculino. Entre mulheres, o gradiente é negativo, com associações lineares e estatisticamente significantes. CONCLUSÃO: Essas características, associadas à forte expansão da obesidade entre adultos jovens detectada em outros estudos, apontam a urgência da utilização de políticas públicas mais incisivas e efetivas, que reduzam a exposição da população à alimentação com má qualidade nutricional e desenvolvam ações voltadas à promoção da atividade física.

Elevated Risk for HIV-1 Infection in Adolescents and Young Adults in São Paulo, Brazil

Background. Recent studies have sought to describe HIV infection and transmission characteristics around the world. Identification of early HIV-1 infection is essential to proper surveillance and description of regional transmission trends. In this study we compare people recently infected (RI) with HIV-1, as defined by Serologic Testing Algorithm for Recent HIV Seroconversion (STARHS), to those with chronic infection. Methodology/Principal Findings Subjects were identified from 2002-2004 at four testing sites in São Paulo. Of 485 HIV-1-positive subjects, 57 (12%) were defined as RI. Of the participants, 165 (34.0%) were aware of their serostatus at the time of HIV-1 testing. This proportion was statistically larger (p<0.001) among the individuals without recent infection (n = 158, 95.8%) compared to 7 individuals (4.2%) with recently acquired HIV-1 infection. In the univariate analysis, RI was more frequent in <25 and >59 years-old age strata (p<0.001). The majority of study participants were male (78.4%), 25 to 45 years-old (65.8%), white (63.2%), single (61.7%), with family income of four or more times the minimum wage (41.0%), but with an equally distributed educational level. Of those individuals infected with HIV-1, the predominant route of infection was sexual contact (89.4%), with both hetero (47.5%) and homosexual (34.5%) exposure. Regarding sexual activity in these individuals, 43.9% reported possible HIV-1 exposure through a seropositive partner, and 49.4% reported multiple partners, with 47% having 2 to 10 partners and 37.4% 11 or more; 53.4% of infected individuals reported condom use sometimes; 34.2% reported non-injecting, recreational drug use and 23.6% were reactive for syphilis by VDRL. Subjects younger than 25 years of age were most vulnerable according to the multivariate analysis. ) Conclusions/Significance In this study, we evaluated RI individuals and discovered that HIV-1 has been spreading among younger individuals in São Paulo and preventive approaches should, therefore, target this age stratum

Effects of different levels of protein intake and physical training on growth and nutritional status of young rats

This study aimed to investigate the effects of physical training, and different levels of protein intake in the diet, on the growth and nutritional status of growing rats. Newly-weaned Wistar rats (n=48) were distributed into six experimental groups: three of them were subjected to physical swim training (1 h per day. 5 d per week, for 4 wk, after 2 wk of familiarization) and the other three were considered as controls (non-trained). Each pair of groups, trained and non-trained, received diets with a different level of protein in their composition: 14%. 21% or 28%. The animals were euthanized at the end of the training period and the following analyses were performed: proteoglycan synthesis as a biomarker of bone and cartilage growth, IGF-I (insulin-like growth factor-I) assay as a biomarker of growth and nutritional status. total RNA and protein concentration and protein synthesis measured in vivo using a large-dose phenylalanine method. As a main finding, increased dietary protein, combined with physical training, was able to improve neither tissue protein synthesis nor muscle growth. In addition, cartilage and bone growth seem to be deteriorated by the lower and the higher levels of protein intake. Our data allow us to conclude that protein enhancement in the diet, combined with physical exercise, does not stimulate tissue protein synthesis or muscle mass growth. Furthermore, physical training, combined with low protein intake, was not favorable to bone development in growing animals

The relationship between birth weight and insulin resistance in childhood

Chronic diseases that are typical of adulthood may originate in intra-uterine life through inadequate fetal development. The present epidemiological cohort study of 506 healthy children aged 5\20138 years evaluated the relationship between birth weight and insulin resistance in an age group that has been assessed in few similar studies. Insulin concentration was determined by chemiluminescence and insulin resistance by the homeostasis model assessment (HOMA). Blood glucose, total cholesterol and fractions (LDL cholesterol and HDL cholesterol) and TAG concentrations were determined by automated enzymatic methods. Linear regression analysis investigated the relationship between birth weight (assessed as a continuous variable and in three categories: small for gestational age, SGA; adequate for gestational age and large for gestational age) and the HOMA index, using backward stepwise selection and biological models to explain the causal pathway of the relationship. There were negativeassociations between birth weight (P < 0·001), SGA (P = 0·027) and the HOMA index, and a positive association between waist circumference (P < 0·001) and the HOMA index. Considering the significant associations between birth weight and waist circumference (P < 0·001) and waist circumference and insulin resistance (P < 0·001), we can probably suspect that lower birth weight is a common cause of higher waist circumference and insulin resistance. In summary, the results of the present study showed increased insulin resistance in apparently healthy, young children, who had lower weight at birth and higher measurements of waist circumference. There is a need to develop public health policies that adopt preventive measures to promote adequate maternal-fetal and child development and enable early diagnosis of metabolic abnormalities
