Prevalence of psychoactive substance use by adolescents in public schools in a municipality in the São Paulo Metropolitan Area, Brazil.

This study aimed to estimate the prevalence of psychoactive substance use by adolescents from public schools. This is a cross-sectional study that used a random sample of adolescents from five public schools located in a municipality in the central-west region of the São Paulo Metropolitan Area, Brazil. Information on demographic, socioeconomic, and drug use was collected using self-report questionnaires.

Spontaneous Orofacial Movements at Writhing and Fidgety General Movements Age in Preterm and Full-Term Infants.

Background: As general spontaneous movements at the writhing and fidgety ages have been important for the early identification of neurodevelopmental impairment of both full-term and preterm infants, the knowledge of the spontaneous orofacial movements at these ages also seems to be important for the diagnosis of oral function, particularly in preterm infants. Therefore, we decided to first classify preterm and full-term infants according to general movements ages, and then to record, describe, compare, and discuss their spontaneous orofacial movements.

Methods: This cross-sectional study included 51 preterm infants (born between 28 and 36 weeks) and 43 full-term infants who were classified at the writhing and fidgety ages of Prechtl's method of general movements assessment.

Nutritional practices and postnatal growth restriction in preterm newborns.

Objective: to assess the nutritional practices in neonatal intensive care units (NICU) associated with growth retardation in premature (preterm) infants.

Methods: retrospective study of preterm infants weighing between 500 and 1,499 g admitted to NICU. Evolution of growth and parenteral (PN) and enteral (EN) nutrition practices were analyzed.

The training of neonatologists and the paradigms implied in their relationship with the parents of babies in the Neonatal Intensive Care Unit.

Objective: To analyze and to interpret the psychological repercussions generated by the presence of parents in the Neonatal Intensive Care Unit for residents in Neonatology.

Methods: Study based on the psychoanalytic theory, involving a methodological interface with qualitative surveys in Health Sciences. Twenty resident physicians in Neonatology, from five public institutions of São Paulo state, responded to a single semi-structured interview.

Premature infants with birth weights of 1500-1999 g exhibit considerable delays in several developmental areas.

Aim: To establish the prevalence and factors associated with developmental scores and delays in premature infants.

Methods: A cross-sectional study was conducted on 100 premature infants with corrected ages of 18-24 months (actual ages 19.9 ± 2.
