Objectives: to describe the assembly of a low-cost paracentesis simulator and evaluate its effectiveness, acceptance and impact on the learning of medical students. Methodology: a paracentesis simulator was built using a mannequin and materials such as plastic bottles, Velcro, polyvinyl chloride sheets and silicone were used. A cross-sectional and experimental study was carried out with undergraduate medical students without previous practical experience with paracentesis, which sought to validate the model, evaluating its benefits in learning and obtaining technical skills. Results: after using the simulator there was an increase of 82.4% in the level of confidence in performing paracentesis in a patient, with 98% of respondents considering that the model fulfilled the simulator function with satisfaction, and 100% considering it useful as a teaching tool. Conclusion: the built simulator was effective as an educational resource, serving as an alternative to high-cost commercial models, allowing for greater accessibility in the use of this tool in medical education.

Parenting practices have been identified as a key determinant of children’s developmental outcomes. The aim of this study was to evaluate the association of parenting practices with child development in a cross-sectional population-based study in a low-income state in northeastern Brazil. The study included data on 3566 caregiver–child pairs, and the children were aged 0–66 months. Positive parenting behaviors (PPBs) were conceptualized in areas of interactive play, social development, and speech and language interactions. Child development was evaluated using the Brazilian Ages and Stages Questionnaire. Linear regression analysis was used to assess the relationships. We found that a greater number of PPBs was associated with better child development domain scores. Among infants < 1 year, each additional PPB was associated with a 0.32 standardized mean difference (SMD) greater communication (95% CI: 0.24–0.41) and 0.38 SMD greater problem-solving scores (95% CI: 0.24–0.52). Among children aged 4–6 years old, each additional PPB was associated with improved communication (SMD: 0.22; 95% CI: 0.13–0.32), problem solving (SMD: 0.21; 95% CI: 0.10–0.32) and personal–social domain scores (SMD: 0.26; 95% CI: 0.17–0.36). Our findings indicate that PPB were robustly associated with better outcomes across developmental domains among Brazilian children. Programs and interventions that support PPB can contribute to improvements in development outcomes.

Estudo qualitativo, exploratório e descritivo, realizado de janeiro a março de 2022, objetivando compreender, à luz da Teoria Bioecológica do Desenvolvimento Humano, os cuidados parentais e as percepções maternas sobre o desenvolvimento dos filhos nascidos durante a pandemia de covid-19. Foram entrevistadas 30 mães. As informações foram submetidas à Análise de Conteúdo. Emergiram três categorias temáticas: cuidados maternos à criança durante a pandemia; aspectos socioafetivos das relações interpessoais das crianças; percepções das mães sobre o desenvolvimento dos filhos. Revelou-se que as mães foram as principais cuidadoras das crianças e as mudanças provocadas pela pandemia impactaram nos cuidados maternos. Apesar das adversidades, as mães procuraram realizar cuidados parentais que desenvolvessem os filhos saudavelmente. Posto que a crise sanitária imposta pela covid-19 continua, recomenda-se, no acompanhamento da saúde materno-infantil, maior atenção à díade mãe-filho, fortalecendo serviços que operem como fontes de apoio às mulheres nos cuidados aos filhos.
