Objective:To assess the prevalence of vitamin D deficiency and its associated factors in women and their newborns in the postpartum period.Methods:This cross-sectional study evaluated vitamin D deficiency/insufficiency in 226 women and their newborns in Viçosa (Minas Gerais, BR) between December 2011 and November 2012. Cord blood and venous maternal blood were collected to evaluate the following biochemical parameters: vitamin D, alkaline phosphatase, calcium, phosphorus and parathyroid hormone. Poisson regression analysis, with a confidence interval of 95%, was applied to assess vitamin D deficiency and its associated factors. Multiple linear regression analysis was performed to identify factors associated with 25(OH)D deficiency in the newborns and women from the study. The criteria for variable inclusion in the multiple linear regression model was the association with the dependent variable in the simple linear regression analysis, considering p<0.20. Significance level was α <5%.Results:From 226 women included, 200 (88.5%) were 20-44 years old; the median age was 28 years. Deficient/insufficient levels of vitamin D were found in 192 (85%) women and in 182 (80.5%) neonates. The maternal 25(OH)D and alkaline phosphatase levels were independently associated with vitamin D deficiency in infants.Conclusions:This study identified a high prevalence of vitamin D deficiency and insufficiency in women and newborns and the association between maternal nutritional status of vitamin D and their infants' vitamin D status.

Objective: To evaluate the “satisfaction” and “self-confidence” constructs in nursing students who underwent simulated clinical experiences in semiology and semiotechnique disciplines. Method: A descriptive study developed with Nursing students from a federal public university in the interior of Minas Gerais through weekly simulated workshops. The “satisfaction” and “self-confidence” constructs were evaluated by the “Student Satisfaction and Self-Confidence with Learning Scale” and “Simulated Clinical Experiences Satisfaction Scale”. Results: The final sample was 45 students. Most were more satisfied (overall average = 4.18) than self-confident (overall average = 4.12). The Spearman correlation test identified a significant and positive association between the “satisfaction” and “self-confidence” constructs. Conclusion: Students feel self-confident and satisfied with the use of simulation as an active teaching-learning methodology, highlighting that the higher the satisfaction level, the greater the student’s self-confidence.

Objetivo: Avaliar o perfil e condições de parto de mulheres atendidas em uma maternidade da Zona da Mata Mineira. Métodos: Estudo transversal, quantitativo, realizado em um hospital filantrópico, localizado na Zona da Mata Mineira. A coleta de dados foi realizada entre março e junho de 2022 por meio de um questionário semiestruturado. Foram realizadas análises descritiva, bivariadas e modelos de regressão logística para estimar a magnitude da associação. Os dados foram analisados no SPSS versão 23. Para a significância estatística foi considerado p<0,05. Resultados: Participaram 272 mulheres, sendo predominante a idade de 20 a 34 anos, não brancas, com ensino médio, baixa renda, casadas ou em união estável e parto entre 38 e 42 semanas. O parto cesáreo teve maior chance de ser realizado entre as mulheres mais velhas, com maiores rendas, maior escolaridade e autodeclaradas brancas, sem companheiros. Verificou-se que o alojamento coletivo, o contato com o bebê no pós-parto imediato, segurar o bebê e amamentar na sala de parto foram mais presentes no parto normal. Conclusão: A maioria das boas práticas de assistência ao parto estão associadas ao parto normal, porém ainda há a necessidade melhorias na assistência da atenção ao parto e humanização do parto cesáreo.

Objective:To evaluate the correlation between the number of leukocytes and cardiovascular risks associated with birth characteristics, nutritional status and biochemical tests.Methods:Cross-sectional study developed with 475 adolescents, born between 1992 and 2001, in the municipality of Viçosa (MG). Maternal medical records were analyzed in the hospital units, and the following was recorded: birth weight and length, head circumference, chest circumference, Apgar score, gestational age. In adolescents, body mass index, skinfold thickness, body composition, blood count, biochemical tests and clinical variables were also assessed. The statistical analyses was carried out using Statistical Package for Social Sciences (SPSS) version 20.0 and Data Analysis and Statistical Software (STATA) with Kruskal–Wallis, Mann–Whitney, chi-square or Fisher's exact tests and Linear Regression. Significance level was set at α<0.05. The study was approved by the Research Ethics Committee of UFV for studies with human subjects.Results:Weight and birth length, head and chest circumference were higher among boys. In adolescents, the number of leukocytes was higher in individuals with excess weight and body fat and high adiposity index, waist-to-height ratio and waist circumference. Only altered triglycerides showed differences between leukocyte medians. Regardless of the anthropometric variable of the final regression model, the stage of adolescence, number of platelets, eosinophils, monocytes and lymphocytes were associated with the increase in leukocytes.Conclusions:The birth variables were not associated with changes in leukocyte numbers, whereas the anthropometric variables were good indicators for a higher leukocyte count, regardless of the stage of adolescence and gender.
