Objective: To estimate the prevalence of adverse childhood experiences and identify associated factors., Methods: A population-based cross-sectional study comprised data from a sample of 3,200 households with 3,566 children under 6 years of age, representative of the state of Ceará, Brazil. A multistage sampling approach was used, with stratification among the state capital, Fortaleza, and the 28 countryside municipalities, in which 160 census tracts were randomly selected, each one with a cluster of 20 households. The outcome variable was structured based on adverse childhood experiences as suggested by the Center for Disease Control and Prevention, according to the number of situations to which the child was exposed: 0-2, 3-5, and 6-9. Ordinal logistic regression multivariate model was applied to assess associations., Results: Among the 3,566 children studied, 89.7% (95%CI 88.7-90.7) were exposed to at least one adverse experience, of which the most prevalent were neglect, and emotional/physical abuse. The main factors associated were maternal advanced age and smoking, paternal absence, low education level of the head of the family, food insecurity and lack of a social support network., Conclusion: The study found a high occurrence of adverse early childhood experiences, particularly among preschool children born to mothers of older age, solo, who smoke and in a situation of social and economic vulnerability, including food insecurity, who should be target of control and prevention measures.

To compare the influence of laser and LED on tissue repair and neuropathic symptoms during treatment of diabetic foot. An intervention survey conducted in a health center located in Brazil, contemplating ten sessions, twice a week, with randomization in two groups. In one group, the wounds were treated with GaAlAs laser, with a wavelength of 830 nm, 30 mW, and power density 0.84 W/cm 2 , the other group by LED 850 nm, 48 mW, and power density 1.05 W/cm 2 . For the analysis of wound size, photographic records analyzed by the ImageJ® software were used, and the neuropathy evaluation card examined. With regard to the laser group, a reduction in wound extension of 79.43% was observed at the end of the 10th session; the patients in the LED group had a 55.84% decrease in the healing process; comparing the two therapies was observed a better healing in the participants of the laser group, with 81.17%, in relation to the LED after the end of the sessions; regarding the evaluation of the neuropathic condition, there was a significant improvement in both therapies. There was improvement of the neuropathic signs and symptoms, also improvement of the tissue repair in the two therapeutic modalities; however, the laser presented a higher rate of speed in relation to the LED.
