Quasi-Experimental study of effects of lighting on rest, activity and melatonin in postpartum women.

Objectives: to compare the parameters of the activity/rest cycle of early postpartum breastfeeding women under a controlled and uncontrolled long wavelength ray light regimen.

Methods: quasi-experimental study with breastfeeding women and their babies during postnatal rooming-in, São Paulo, Brazil. Participants were allocated to either an experimental (intervention) or a comparison group.

Risk and protective factors for sudden infant death syndrome.

Objectives: To verify the occurrence of the risk and protective factors for sudden infant death syndrome during nursing consultation.

Methods: Retrospective cohort study conducted based on medical records from a primary care unit in the municipality of São Paulo. The sample consisted of 63 infants assisted from January to December 2016.

Influence of Ear Protectors on the Sleep of Preterm Newborns: A Randomized Controlled Clinical Study.

The purpose of this study was to compare the effect of ear protectors on the sleep of preterm newborns during the "quiet" times in intermediate care nursery. This was a clinical, randomized, controlled crossover study conducted in two neonatal units in São Paulo, Brazil. The sample consisted of preterm infants who met the inclusion and exclusion criteria for the study.

Correlation of Premature Infant Sleep/Wakefulness and Noise Levels in the Presence or Absence of "Quiet Time".

Background: Peak sound levels during sleep can compromise the development of hospitalized infants. Quiet time is a strategy implemented in neonatal units to promote the sleeping of neonates by reducing noise levels, luminosity, and handling during particular periods of the day.

Purpose: To determine the impact of quiet time on reducing sound levels and increasing total sleep time.

Sleep and salivary cortisol in preterm neonates: a clinical, randomized, controlled, crossover study.

Objective: Analyze the influence of ear protectors on the baseline levels of salivary cortisol and response and total sleep time of preterm neonates during two periods of environmental management of a neonatal intermediate care unit.

Method: A clinical, randomized, controlled and crossover study conducted with 12 preterm neonates. The use of ear protectors was randomized in two periods.

Effects of Handling and Environment on Preterm Newborns Sleeping in Incubators.

Objective: To describe the total sleep time, stages of sleep, and wakefulness of preterm newborns and correlate them to levels of sound pressure, light, temperature, relative air humidity, and handling inside incubators.

Design: Observational, correlational study.

Setting: A neonatal intermediate care unit.

Effect of sleeping position on arousals from sleep in preterm infants.

Purpose: To evaluate the frequency of preterm infant positions during sleep, and to investigate the association among positions, arousals, sleep patterns, and time of day.

Design And Methods: This observational study was conducted in a neonatal unit with 10 preterm infants. Polysomnographic and video recordings during 24 hr identified sleep positions, arousals, sleep patterns, and time of day.

Polysomnography assessment of sleep and wakefulness in premature newborns.

Objective: to describe the total sleep time and its stages, total wake time, heart rate values and oxygen saturation shown by premature infants, and the influence of the periods of the day on sleep and physiological parameters.

Method: a descriptive study was conducted of 13 hospitalized premature infants. Data collection was performed using polysomnography and unstructured observation for 24 uninterrupted hours.

[Effect of reducing sensory and environmental stimuli during hospitalized premature infant sleep].

Objective: To compare the total sleep time of premature infant in the presence or absence of reducing sensory and environmental stimuli in the neonatal unit.

Method: Longitudinal study in a Neonatal Intermediate Care Unit of a public hospital in Sao Paulo. The sample consisted of 13 premature infants.

[Workers' knowledge and perception regarding noise in the neonatal unit].

The objective of the study was to assess the knowledge and perception of professionals working in a Neonatal Intensive Care Unit (NICU) regarding the repercussions of noise on the neonates, families and workers, prior to the implementation of an educational program. This qualitative descriptive study was conducted in a NICU of a São Paulo hospital with 101 professionals. A questionnaire was used for data collection, and chi-square and Student's t test were used to determine the association between variables.

[Sound pressure levels in the neonatal intensive care unit].

The objectives of the study were to assess sound pressure level (SPL) in two rooms of a Neonatal Intensive Care Unit (NICU) and to identify their sources. This quantitative-descriptive study was conducted in two rooms of a NICU of a University Hospital in São Paulo, Brazil. Three dosimeters were used to register SPL (total of 261 hours).

Noise at the neonatal intensive care unit and inside the incubator.

The goal was to identify sound pressure level (SPL) at the neonatal intensive care unit (NICU) and inside the incubator of a teaching hospital of a public university from São Paulo - SP, Brazil. SPL inside the NICU and the incubator were measured using four dosimeters in January/2010. SPL at the NICU varied from 52.

[Perceptions of newborns' families about the communication of bad news].

The present study aims to describe how families perceive the communication of bad news about hospitalized newborns given by professionals. A qualitative and descriptive study was carried out with families of hospitalized newborns in the neonatal unit. Five mothers and one father were interviewed The thematic analysis of data revealed four categories: Message content in relation to clarity, detailing and not disclosed information.

The meaning of interaction between nursing professionals and newborns/families in a hospital setting.

This study aimed to understand the meaning of the nursing team's communication with newborns and families during care delivered in a neonatal unit and also to develop a theoretical model. Symbolic Interactionism and Hargie's model were used as theoretical and Grounded theory as the methodological reference framework. The study was carried out at the nursery of a hospital in São Paulo, SP, Brazil.

[The use of videotaping in qualitative research].

Considering advancements in data collection methods, we explore the use of videotaping in qualitative research. This bibliographical study aims at developing reflections on the possibilities of using videotapes in research and at providing material to researchers. The video is used as an instrument of data collection and generation.

[Analysis of the care delivered to hospitalized newborns according to the Winnicottian perspective].

This work aimed to analyze the holding provided by nurse aides, nurses, mothers, and fathers to infants newborn hospitalized at the middle risk neonatal unit of a university hospital in the city of São Paulo. This is a qualitative descriptive study based on Winnicott's theoretical framework. Data were collected by means of videotaping.
