Conhecimento das puérperas em relação ao parto humanizado e às vias de parto / Knowledge of puerperal women towards humanized delivery and modes of delivery

Objetivo: Avaliar o conhecimento das puérperas em relação ao parto humanizado e às vias de parto. Métodos: Estudo observacional transversal com 369 puérperas que realizaram seu parto em um hospital público de Curitiba, Paraná, Brasil. Aplicação de dois questionários que avaliaram características demográficas e socioeconômicas, informações sobre a gestação e o pré-natal, conhecimento de humanização e vias de parto, e atitude em relação às vias de parto. Resultados: Entre as puérperas, 72% afirmaram já terem ouvido falar no termo "parto humanizado", porém, dessas, 52,6% deram uma definição inadequada. E 48,2% obtiveram baixo conhecimento acerca das vias de parto, e 58,2% expressaram atitude positiva em relação à cesárea. Houve associação entre conhecimento prévio sobre parto humanizado e renda (p = 0,001), escolaridade (p < 0,0001), número de consultas de pré-natal (p = 0,023), busca de informações sobre as vias de parto (p < 0,0001) e preferência de parto (p = 0,011). Houve correlação do conhecimento acerca das vias de parto com renda (p = 0,044), escolaridade (p = 0,003), busca de informações sobre as vias de parto (p = 0,007) e atitude em relação à cesárea (p < 0,0001). Conclusão: Observou-se baixo conhecimento acerca das vias de parto e parto humanizado, e características como renda, escolaridade, busca por informações de forma independente e número de consultas de pré-natal possuem associação com esses conhecimentos. Um pré-natal com adequada transmissão de conhecimento relaciona-se à preferência pelo parto normal, sendo essa uma estratégia para a redução das taxas de cesárea e, consequentemente, da morbimortalidade materno-fetal.

Objective: To evaluate the knowledge of postpartum women in relation to humanized del ivery and delivery methods. Methods: Cross-sectional observational study with 369 postpartum women who delivered in a public hospital in Curitiba, Paraná, Brazil. Application of two questionnaires, which evaluated demographic and socioeconomic characteristics, information about pregnancy and prenatal care, knowledge of humanization and delivery methods, attitude towards delivery methods. Results: 72% of postpartum women said they had already heard the term "humanized childbirth", however, of these 52.6% gave an inadequate definition. 48.2% had low knowledge about delivery methods. 58.2% expressed a positive attitude towards cesarean section. There was an association between prior knowledge about humanized childbirth and income (p = 0.001), schooling (p < 0.0001), number of prenatal consultations (p = 0.023), search for information about delivery methods (p < 0 .0001), birth preference (p = 0.011). There was a correlation between knowledge about the modes of delivery with income (p = 0.044), education (p = 0.003), search for information about the modes of delivery (p = 0.007), attitude towards cesarean section (p < 0.0001). Conclusion: There was a low knowledge about the ways of delivery and humanized delivery, and characteristics such as income, education, search for information independently and the number of prenatal consultations have an association with this knowledge. A prenatal care with adequate transmission of knowledge is related to the preference for normal delivery, which is a strategy for reducing cesarean rates and, consequently, maternal-fetal morbidity and mortality.

No association between dopamine D2 receptor (DRD2) alleles and crack/cocaine dependence in Brazilians

INTRODUCTION: The causal mechanisms behind crack/cocaine use are still unknown, but genetic influences are suggested. OBJECTIVE: To investigate the relationship between the genetic polymorphism TaqI (rs1800497) in the dopamine D2 receptor (DRD2) gene and susceptibility to crack/cocaine dependence in a group of addicts to crack/cocaine and a non-addicted group. METHODS: The case group (n=515) was composed of crack/cocaine-dependent men and the control group (n=106) comprised men who were considered not dependent on crack/cocaine. The oral hygiene habits, decayed, missing, and filled teeth index, gingival index, and plaque index were evaluated. The reference single nucleotide polymorphism (rs1800497 C/T) of the DRD2 gene was genotyped by a real-time polymerase chain reaction technique. Student's t-tests for independent samples or the non-parametric Mann-Whitney test were used to compare groups regarding quantitative variables. RESULTS: The case group showed a mean time of 9.91±7.03 years of crack use, and 61.06±92.96 stones/week. The socio-demographic profile of the sample was White, single men, with basic education, blue-collar worker, smoker, and reporting alcohol use. There was a high frequency of gingival inflammation, plaque accumulation, and caries experience. For all genetic models tested, there was no significant difference in the genotypic frequency in rs1800497 of the DRD2 gene, between case and control groups (p>0.05). CONCLUSION: The genetic variant in the DRD2 did not increase the vulnerability to develop crack/cocaine dependence. The complex genetic nature of crack/cocaine dependence and a large variation of DRD2 allele frequencies, depending on the population group sampled, could be one explanation for the no association.
