Aim. To assess the relationship of the anthropometric parameters of girls with the development of vulvovaginitis and the duration of breastfeeding. Materials and methods. To achieve this goal, 175 prepubertal girls at the age of 3-6 years, 73 girls with vulvovaginitis (main group) and 102 girls examined at a routine preventive examination in a children’s polyclinic without symptoms or signs of vulvovaginitis were examined, constituted a comparison group. When analyzing the anthropometric data of girls, we used the centile tables of M. Dementyev and B. I. Ilyina. Patients with a history of suspected sexual abuse or suspected vaginal foreign body were excluded from the study. Legal representatives of the subjects were informed about the purpose of the study and gave written informed voluntary consent. As part of a survey of the child’s legal representatives and copying data from outpatient cards, information was obtained about the mother’s obstetric and gynecological history, the child’s height and weight at birth, and the child’s height and weight at the time of the examination was assessed. Evaluation of the nature of feeding was carried out in 174 girls (1 girl was adopted). The processing of statistical data and the establishment of statistical significance was carried out using the chi-square test. Differences with a significance level of P < 0.05 were considered statistically significant. The method of multiple logistic regression was used to establish the influence of the child’s anthropometric data on the likelihood of vulvovaginitis and the relationship with the presence and duration of lactation. Results. There is a relationship between the anthropometric data of girls at birth and at the age of 3 to 6 years and the development of vulvovaginitis. In the group with vulvovaginitis, girls with a weight-growth coefficient at birth less than 3 centile (p = 0.044) were less common, and vulvovaginitis developed 2.79 times more often (95% CI: 1.2-6.53) in girls with overweight and obesity between the ages of 3 and 6. There is no relationship between the anthropometric data of the child, the presence and duration of breastfeeding. Conclusion. It was established that there is a relationship between the anthropometric data of girls at birth and at the age of 3-6 years and the development of vulvovaginitis. In the group with vulvovaginitis, girls with a weight-growth coefficient at birth less than 3 centile (p = 0.044) were less common, and vulvovaginitis developed 2.79 times more often in girls with overweight and obesity at the age of 3-6 years (95% CI: 1.2-6.53). There is no relationship between the anthropometric data of the child, the presence and duration of breastfeeding.

This paper, as a tool for analysis, considered the capacity of the interaction that open systems have against the occurrence of disturbances so that they can continue to function with minimal losses of energy, called resilience, an emerging characteristic of agroecosystems. To establish a method to measure this characteristic, ten variables were evaluated, including seven cultural variables: level of schooling, land tenure type, saving capacity, social organizational identity, farm infrastructure, weed control and production system; and three ecosystem variables: water resource availability, phytosanitary management and Main Agroecological Structure (MAS) in typical citrus fruit agroecosystems. These were methodologically grouped into six recommended domains: groups of farms and citrus growers with similar ecosystem and cultural conditions that have been characterized and typified in a previous study. In each of these groups, three farm types were selected for a total of 18 production units (department of Meta, Colombia). To determine the difference between the variables, Chi-square tests were applied (using the Pearson and Fisher statistics). Network analysis was applied to determine the relationship between the variables. The resilience was not significantly correlated with level of schooling, farm infrastructure or MAS. The relationship between the resilience and cultural variables presented a high significance, whereas the ecosystem variables showed a low statistical significance.

Introduction: Many doctors are leaving Nepal to work abroad. To understand this problem better, we decided to study the attitude and plans of young doctors and medical students. Materials and methods: This cross-sectional study was conducted at Kathmandu Medical College involving 65 firstyear medical students, 100 interns and 100 house officers. The data collected was entered in Microsoft excel and analysed by SPSS (Statistical Package for Social Sciences) programme. Chi-square test was used to compare two proportions. Significance level was set at 5%. Results: Only 2% house officers said that their job prospects were excellent as compared to 22.4% of students, whereas 20% house officers as compared to 9% students thought job prospects in Nepal were poor (p= 0.003). Eighty two percent of students thought that a doctor's service to his country was very important as compared to 51% of interns (p=‹ 0.001) and 58% of house officers. Forty percent of students, 58% of interns and 48% of house officers (no statistical significance between the three groups) planned to migrate to a developed country after graduation. Eighty eight percent of students, 89% interns and 74% of house officers (no statistical significant differences between the three groups) were of the opinion that improving career opportunities or working environment of the doctor could make the profession more attractive. Conclusion: Although majority of students, interns and house officers were of the opinion that a doctor's service to his community/country was very important, almost half of them still planned to migrate to a developed country after graduation. Improving the chances of professional advancement and professional working environment can make the profession more attractive, and therefore, may decrease this tendency for brain drain from our country.

ABSTRACT OBJECTIVE The objective of this study is to estimate the seroprevalence of human brucellosis in livestock professionals and analyze the factors associated with brucellosis focusing on sociodemographic variables and the variables of knowledge and practices related to the characteristics of the activities carried out in livestock. METHODS This is a cross-sectional seroepidemiological study with a population of 131 workers of butchers, slaughter rooms, and slaughterhouse and 192 breeders sampled randomly in Namibe province, Angola. The data were obtained from the collection of blood and use of questionnaires. The laboratory tests used were rose bengal and slow agglutination. The questionnaire allowed us to collect sociodemographic information and, specifically on brucellosis, it incorporated questions about knowledge, attitudes, and behaviors of livestock professionals. In addition to the descriptive statistical approach, we used the Chi-square test of independence, Fisher’s test, and logistic regression models, using a significance level of 10%. RESULTS The general weighted prevalence of brucellosis was 15.6% (95%CI 13.61–17.50), being it 5.3% in workers and 16.7% (95%CI 11.39–21.93) in breeders. The statistical significance was observed between human seroprevalence and category (worker and breeder) (p < 0.001) and education level (p = 0.032), start of activity (p = 0079), and service location (p = 0.055). In a multivariate context, the positive factor associated with brucellosis in professionals was the professional category (OR = 3.54; 95%CI 1.57–8.30, related to breeders in relation to workers). CONCLUSIONS Human brucellosis in livestock professionals is prevalent in Namibe province (15.6%), where the professional category was the most important factor. The seroprevalence levels detected are high when compared with those found in similar studies.

Summary Objective: To determine overweight and obesity prevalence in preschool children from public education, and to determine their relation to food consumption. Method: Cross-sectional study with children aged between 2 and 5 years, of both sexes, enrolled at municipal day care centers. Socioeconomic, demographic and anthropometric data were collected, in order to calculate the body mass index (BMI) for age. Data on food consumption were assessed using a Food Frequency Questionnaire. χ2 test, Kruskal-Wallis test, Student's t-test and Pearson's correlation were used at a significance level of 5%. Results: Of 548 children, 52% were male, with mean age of 4.2 years old. Most families had incomes between 1 and 2 minimum wages (59.7%), in addition to 10 years (mothers) of education. Anthropometric parameters did not differ significantly between sexes. According to the BMI-for-age, it was found that most of children were well-nourished (85.2%), 8.2% had the risk of becoming overweight, and 4.2% were overweight. The most consumed foods were: rice (100%), beans (99.4%), bread (98.5%), fruit (98.5%), red meat (97.1%), butter and margarine (95.4%), biscuits, cakes and sweet pies (94.1%), dairy products (94.1%), chocolate milk (91.7%), and soft drinks (90.2%). Consumed foods that were strongly correlated (r > 0.7) to the risk of/excess weight were, as follows: bread; biscuits, cakes, sweet pies; dairy products; chocolate milk; sausages. Conclusion: There was low prevalence of overweight and absence of obesity among the population assessed. The risk of overweight was greater among girls. Data from the study showed deviations in food consumption.
